    Clinical studies regarding complete cure rate of onychomycosis using oral Terbinafine have a very broad range (14-90%) based solely on response to treatment on the big toenail. To evaluate the efficacy of Terbinafine in all affected onychomycotic toenails and, furthermore, to evaluate differences in mycological, clinical and complete cure rate between affected onychomycotic toenails. Inclusion criteria are as follows: distolateralsubungual onychomycotic involvement of the hallux and additional involvement of at least two more toenails of the same foot. Exclusion criteria are as follows: patients with nail traumata and hypersensitivity to Terbinafine. Patients were treated with oral Terbinafine 250 mg/day for 16 weeks. Mycological analysis was performed using direct microscopy and culture. Clinical improvement was assessed using digital photography. Statistically significant difference was found in clinical improvement between the great toenail and all other involved toenails. The rate of complete cure (100% clinical cure and mycological cure) of the big toenail was lower (23%) as compared to the second (65%), third (51%) and the fourth toenail (67%). This is a case series study that was based on a single-centre cohort. Our results support findings that efficacy of Terbinafine should be based on all involved onychomycotic toenails; the big toenail is not superior in response compared to other affected toenails. © 2014 European Academy of Dermatology and Venereology.

    Full Text Available Introduction  Self-efficacy in clinical performance had an important role in applying competencies; also competencies and self-efficacy in clinical performance influenced to quality care of nursing and midwifery students. So the present study aimed to define the relationship between clinical competencies and clinical self-efficacy among nursing and midwifery students. Materials and Methods  This is a cross-sectional study conducted on 150 of nursing and midwifery students in Isfahan University of Medical Science, selected through two stage sampling in 2014. The participant completed questionnaires about personal/ educational characteristics and nursing competencies questionnaire (18 items and clinical self-efficacy scale (37 items. The data were analyzed by, Pearson statistical test, t-test, variance analysis through SPSS version16. Results The results showed that 50% (n=75 and 37.4% (n=56 of nursing and midwifery students had good clinical competence and clinical Self-Efficacy, respectively. Also the mean competencies and self-efficacy in clinical performance scores were 35.05± 1.2 and 76.03± 0.4 respectively. Pearson correlation coefficient showed that there was a positive linear correlation between the score of clinical competence and clinical self-efficacy (P

    During clinical rotations, students move from one clinical situation to another. Questions exist about students' strategies for coping with these transitions. These strategies may include a process of social comparison because in this context it offers the student an opportunity to estimate his or her abilities to master a novel rotation. These estimates are relevant for learning and performance because they are related to self-efficacy. We investigated whether student estimates of their own future performance are influenced by the performance level and gender of the peer with whom the student compares him- or herself. We designed an experimental study in which participating students (n = 321) were divided into groups assigned to 12 different conditions. Each condition entailed a written comparison situation in which a peer student had completed the rotation the participant was required to undertake next. Differences between conditions were determined by the performance level (worse, similar or better) and gender of the comparison peer. The overall grade achieved by the comparison peer remained the same in all conditions. We asked participants to estimate their own future performance in that novel rotation. Differences between their estimates were analysed using analysis of variance (ANOVA). Students' estimates of their future performance were highest when the comparison peer was presented as performing less well and lowest when the comparison peer was presented as performing better (p influences students' estimates of their future performance in a novel rotation. The effect depends on the performance level and gender of the comparison peer. This indicates that comparisons against particular peers may strengthen or diminish a student's self-efficacy, which, in turn, may ease or hamper the student's learning during clinical rotations. The study is limited by its experimental design. Future research should focus on students' comparison behaviour in real transitions

    Treatment with long-acting injectable (LAI) antipsychotic medication is an important element of relapse prevention in schizophrenia. Recently, the intramuscular once-monthly formulation of aripiprazole received marketing approval in Europe and the United States for schizophrenia. This study aimed to compare aripiprazole once-monthly with other LAI antipsychotics in terms of efficacy, tolerability, and safety. A systematic literature review was conducted to identify relevant double-blind randomized clinical trials of LAIs conducted in the maintenance treatment of schizophrenia. MEDLINE, MEDLINE In-Process, Embase, the Cochrane Library, PsycINFO, conference proceedings, clinical trial registries, and the reference lists of key review articles were searched. The literature search covered studies dating from January 2002 to May 2013. Studies were required to have ≥24 weeks of follow-up. Patients had to be stable at randomization. Studies were not eligible for inclusion if efficacy of acute and maintenance phase treatment was not reported separately. Six trials were identified (0.5% of initially identified studies), allowing comparisons of aripiprazole once-monthly, risperidone LAI, paliperidone palmitate, olanzapine pamoate, haloperidol depot, and placebo. Data extracted included study details, study duration, the total number of patients in each treatment arm, efficacy, tolerability, and safety outcomes. The efficacy outcome contained the number of patients that experienced a relapse, tolerability outcomes included the number of patients that discontinued treatment due to treatment-related adverse events (AEs), and that discontinued treatment due to reasons other than AEs (e.g., loss to follow-up). Safety outcomes included the incidence of clinically relevant weight gain and extrapyramidal symptoms. Data were analyzed by applying a mixed treatment comparison competing risks model (efficacy) and using binary models (safety). There was no statistically significant

    Full Text Available Background: The most common technique to anesthetize mandibular primary teeth is inferior alveolar (I.A nerve block injection which induces a relatively sustained anesthesia and in turn may potentially traumatize soft-tissues. Therefore, the need of having an alternative technique of anesthesia with a shorter term but the same efficacy is reasonable. The aim of this study was a comparison of the efficacy of two anesthetic techniques of mandibular primary first molar. Materials and Methods: In this randomized crossover clinical trial, 40 children with ages ranged from 5 years to 8 years whose mandibular primary first molars were eligible for pulpotomy, were selected and divided randomly into two groups. The right and left mandibular first molars of group A were anesthetized with infiltration and I. A nerve block techniques in the first and second sessions respectively. The left and right mandibular first molars of group B were anesthetized with I.A nerve block and infiltration techniques in the first and second sessions respectively. The severity of pain were measured and recorded according to sound-eye-motor scale by a certain person. Data was analyzed using Wilcoxon Signed Rank and Mann-Whitney U tests (P < 0.05. Results: The severity of pain was lower in infiltration technique versus I.A nerve block. There were no significant differences between the severities of pain on pulpal exposure of two techniques. Conclusion: It seems that infiltration technique is more favorable to anesthetize the mandibular primary first molar compared to I.A nerve block.

    Bifrontal (BF) placement of electrodes in electroconvulsive therapy (ECT) has become a popular alternative to bitemporal (BT) placement. This study compares the clinical efficacy, side effects, and rehospitalization rates of BT and BF electrode placement in a community hospital setting. Charts from 76 patients receiving ECT treatments at Harborview Medical Center from 1994 to 2000 were reviewed to extract data on the characteristics of the course of ECT, clinical response, total headaches, narcotic and nonsteroidal anti-inflammatory drug doses, as well as documentation of confusion, disorientation, memory loss, and treatment emergent need for assistance with activities of daily living. The BT patients experienced more clinical improvement during their stay (a 7-point greater change in Psychiatric Symptom Assessment Scale score, P < 0.05) and were significantly less likely to be rehospitalized within a 1-year time frame (odds ratio = 4.9, P = <0.05), even after controlling for relevant covariates. Although the two patient groups had equal rates of headache and analgesic administration, the BT placement caused significantly more cognitive impairment. This study suggests that BT electrode placement offers better efficacy but modestly greater cognitive impairment than BF electrode placement.

    Clinical nurses play a vital role in clinical practice education; thus, it is necessary to help clinical nurses have teaching efficacy through the development and application of systematic education programs. To identify nurses' teaching efficacy for clinical education and analyze the influencing factors of teaching efficacy. The study used a cross-sectional design. We used a convenience sample of 263 nurses from two hospitals. Teaching efficacy, general characteristics, and perception of clinical practice education were collected via self-reported questionnaires. Teaching efficacy was measured using Hwang's (2006) questionnaire, while perception of clinical practice education was measured using the Clinical Nurse Teacher Survey developed by Nishioka et al. (2014). Participants completed the questionnaire directly. The collected data were then analyzed using descriptive statistics, t-tests, ANOVAs, and multiple regression analysis with PASW Statistics 18.0. The mean total score of teaching efficacy was 72.5 (range 21-105). The leadership for students subscale had the highest score (3.56±0.59). The factors influencing teaching efficacy were length of clinical career (β=0.26, pteaching efficacy in nurses. Based on these results, nursing educators might need to develop greater confidence in their knowledge and enhance control of their teaching strategies. Nursing schools and hospitals might need to provide greater support and educational opportunities to nurse clinical practice instructors. Furthermore, constructing a system of cooperation between these colleges and educational hospitals, developing programs to enhance teaching efficacy, and identifying the clinical instructor's role are all necessary to promote clinical practice education.

    This paper explored the present status of self-efficacy and job involvement of clinical nursing teachers and investigated the predictive power of teachers' personal background variables on such, as well as the relationship between self-efficacy and job involvement. A total of 419 participants in the survey sample were chosen among clinical nursing teachers at 19 public and private institutes of technology and junior colleges in Taiwan in 2004. The self-developed structural questionnaire was categorized into three sections, including personal background data, job self-efficacy related to the clinical teaching inventory and job involvement related to clinical teaching inventory. Of the total 419 questionnaires distributed for this cross-sectional survey, 266 valid copies were registered, at a recovery rate of 63%. Findings indicated that both the job self-efficacy and job involvement of clinical nursing teachers are at a medium to high level and that significant differences exist in job self-efficacy and job involvement based on differences in age, marital status, teaching seniority, teacher qualifications, and job satisfaction. Second, samples have significantly different performance in self-efficacy due to differences in education level attained and the medical institution to which nursing teachers had been assigned. Self-efficacy and job involvement are significantly positively correlated. These results can serve as a reference for the cultivation of nursing teachers and reform of clinical nursing education in the future.

    The aim of this study is analysing the impact of the systematic versus occasional videoconferencing discussion of patients with two respiratory referral units along 6 years of time over the efficiency of the in-person outpatient clinics of a thoracic surgery service. Retrospective and comparative study of the evaluated patients through videoconferencing and in-person first visits during two equivalents periods of time: Group A (occasional discussion of cases) between 2008-2010 and Group B (weekly regular discussion) 2011-2013. Data were obtained from two prospective and electronic data bases. The number of cases discussed using e-consultation, in-person outpatient clinics evaluation and finally operated on under general anaesthesia in each period of time are presented. For efficiency criteria, the index: number of operated on cases/number of first visit outpatient clinic patients is created. Non-parametric Wilcoxon test is used for comparison. The mean number of patients evaluated at the outpatient clinics/year on group A was 563 versus 464 on group B. The median number of cases discussed using videoconferencing/year was 42 for group A versus 136 for group B. The mean number of operated cases/first visit at the outpatient clinics was 0.7 versus 0.87 in group B (P=.04). The systematic regular discussion of cases using videoconferencing has a positive impact on the efficacy of the outpatient clinics of a Thoracic Surgery Service measured in terms of operated cases/first outpatient clinics visit.

    Frequency and torment caused by migraines direct patients toward a variety of remedies. Few studies to date have proposed ginger derivates for migraine relief. This study aims to evaluate the efficacy of ginger in the ablation of common migraine attack in comparison to sumatriptan therapy. In this double-blinded randomized clinical trial, 100 patients who had acute migraine without aura were randomly allocated to receive either ginger powder or sumatriptan. Time of headache onset, its severity, time interval from headache beginning to taking drug and patient self-estimation about response for five subsequent migraine attacks were recorded by patients. Patients(,) satisfaction from treatment efficacy and their willingness to continue it was also evaluated after 1 month following intervention. Two hours after using either drug, mean headaches severity decreased significantly. Efficacy of ginger powder and sumatriptan was similar. Clinical adverse effects of ginger powder were less than sumatriptan. Patients' satisfaction and willingness to continue did not differ. The effectiveness of ginger powder in the treatment of common migraine attacks is statistically comparable to sumatriptan. Ginger also poses a better side effect profile than sumatriptan.

    Full Text Available Sucralfate enema has been proposed and investigated in treatment of ulcerative proctitis, but its efficacy is still a matter of debate. Hydrocortisone enema is still an established drug in treatment of ulcerative proctitis. This study was designed to compare the effect of sucralfate enema with hydrocortisone enema. Patients with active sigmoidoscopic and histologic features of ulcerative proctitis were included. All patients had clinical manifestations of proctitis for at least four weeks prior to the study and had negative parasitic stool culture. The total of 25 patients entered the study. They were randomly divided in two groups; group I (n =14 and group II (n = 11 who received sucralfate and hydrocortisone enemas respectively for 4 weeks. Both groups had a significant improvement in clinical features, histologic activity and sigmoidoscopic evaluation in comparison with the baseline. Furthermore there was no significant differences between the two groups concerning mean changes of clinical, sigmoidoscopic, and histologic grading, after treatment. Considering the low cost and minimal adverse effects of sucralfate, and almost equal efficacy in comparison with hydrocortisone enema, its usage can be recommended.

    The effect of thermotherapy in the treatment of skin warts in comparison to cryotherapy, as the standard conventional method, has remained uncertain. This study aimed to assess the clinical efficacy and safety of thermotherapy and cryotherapy in removing skin warts. This randomized controlled trial was conducted on 52 patients aged 18 years and over with ≤ 10 skin warts. The participants were randomly assigned into two groups to receive cryotherapy (every 2 to 3 weeks up to six sessions if required) or thermotherapy (one session). The patients in both groups were followed every 2 to 3 weeks for the first three months, and then three months after the last treatment session. The clearance rate was 79.2% in the thermotherapy group and 58.3% in the cryotherapy group with no significant difference (p = 0.212). The rate of scarring in the thermotherapy group was 20% (p = .018). A higher clearance rate was achieved in the thermotherapy group. However, this result was not statistically significant. There were some minimal post-treatment complications. Patients needed only one session of thermotherapy. Due to the risk of scarring, we suggest thermotherapy only as a suitable treatment method for palmoplantar warts. © 2017 Wiley Periodicals, Inc.

    Drug attrition in oncology clinical development is higher than in other therapeutic areas. In this context, pharmacometric modeling represents a useful tool to explore drug efficacy in earlier phases of clinical development, anticipating overall survival using quantitative model-based metrics. Furthermore, modeling approaches can be used to characterize earlier the safety and tolerability profile of drug candidates, and, thus, the risk-benefit ratio and the therapeutic index, supporting the design of optimal treatment regimens and accelerating the whole process of clinical drug development. Areas covered: Herein, the most relevant mathematical models used in clinical anticancer drug development during the last decade are described. Less recent models were considered in the review if they represent a standard for the analysis of certain types of efficacy or safety measures. Expert opinion: Several mathematical models have been proposed to predict overall survival from earlier endpoints and validate their surrogacy in demonstrating drug efficacy in place of overall survival. An increasing number of mathematical models have also been developed to describe the safety findings. Modeling has been extensively used in anticancer drug development to individualize dosing strategies based on patient characteristics, and design optimal dosing regimens balancing efficacy and safety.

    Cryotherapy is a local treatment for cutaneous leishmaniasis with variable efficacy and greater safety than conventional treatment. The objective of this study is to evaluate the efficacy and safety of cryotherapy for the treatment of cutaneous leishmaniasis and to compare it with pentavalent antimonials. A meta-analysis based on a search of nine databases with eight strategies was conducted. Inclusion and exclusion criteria were applied, the methodological quality of each article was evaluated, and the reproducibility of the study selection and information extraction from each clinical trial was assured. The per lesion and per patient efficacy was calculated, and a meta-analysis of relative risks with the random effects model and the Dersimonian and Laird's, Begg, and Egger tests, along with a sensitivity analysis, were performed. A meta-regression based on the methodological quality of the trials included was also performed. Eight studies were included in which respective per lesion efficacies of 67.3 % and 67.7 % were reported for cryotherapy and pentavalent antimonials. In 271 patients treated with cryotherapy and in 199 with pentavalent antimonials, respective per protocol and intent to treat efficacies of 63.6 % and 54.2 % were found in the first group, and per protocol and intent to treat efficacies of 74.7 % and 68.3 % were found in the second group. The relative risk for the comparison of efficacy in the two groups was 0.73 (0.42-1.29). The results of the sensitivity analysis and the meta-regression analysis of relative risks were statistically equal to the overall results. This investigation provides evidence in favor of the use of cryotherapy given that its efficacy is similar to that of pentavalent antimonials.

    Functional constipation is prevalent in children. Recently polyethylene glycol has been introduced as an effective and safe drug to treat chronic constipation. There are only a few clinical trials on comparison of PEG and liquid paraffin in childhood constipation. The purpose of this study was to evaluate clinical efficacy and safety of PEG 3350 solution and liquid paraffin in the treatment of children with functional constipation in Sari Toba clinic during the period of 2008-2009. Children with a history of functional constipation were subjects of this study. One hundred and sixty children of 2-12 years old with functional constipation were randomized in two PEG and paraffin treatment groups. Patients received either 1.0-1.5 g/kg/day PEG 3350 or 1.0-1.5 ml/kg/day liquid paraffin for 4 months. Clinical efficacy was evaluated by stool and encopresis frequency/week and overall treatment success rate was compared in two groups. Compared with the baseline, defecation frequency/ week increased significantly and encopresis frequency meaningfully decreased in two groups during the period of the study. Patients using PEG 3350 had more success rate (mean: 95.3%±3.7) compared with the patients in paraffin group (mean: 87.2%±7.1) (p=0.087). Administration of PEG 3350 were associated with less adverse events than liquid paraffin. In conclusion in treatment of pediatric functional constipation, regarding clinical efficacy and safety, PEG 3350 were at least as effective as liquid paraffin and but less adverse drug events.

    Clinical education is vital to both the development of clinical self-efficacy and the integration of future nurses into health care teams. The dedicated education unit clinical teaching model is an innovative clinical partnership, which promotes skill development, professional growth, clinical self-efficacy, and integration as a team member. Blended clinical teaching models are combining features of the dedicated education unit and traditional clinical model. The aims of this study are to explore how each of three clinical teaching models (dedicated education unit, blended, traditional) affects clinical self-efficacy and attitude toward team process, and to compare the dedicated education unit model and blended model to traditional clinical. A nonequivalent control-group quasi-experimental design was utilized. The convenience sample of 272 entry-level baccalaureate nursing students included 84 students participating in a dedicated education unit model treatment group, 66 students participating in a blended model treatment group, and 122 students participating in a traditional model control group. Perceived clinical self-efficacy was evaluated by the pretest/posttest scores obtained on the General Self-Efficacy scale. Attitude toward team process was evaluated by the pretest/posttest scores obtained on the TeamSTEPPS® Teamwork Attitude Questionnaire. All three clinical teaching models resulted in significant increases in both clinical self-efficacy (p=0.04) and attitude toward team process (p=0.003).

    Pulmonary rehabilitation (PR) improves functional exercise capacity and health status in people with chronic obstructive pulmonary disease (COPD), although these outcomes are often not maintained following PR. Self-efficacy is a precursor to outcomes achievement, yet few studies have examined the importance of self-efficacy to outcome improvement during PR, or how it develops over time. Further, the contribution of exercise-specific self-efficacy to outcomes in PR is unknown. The aims of this study were to determine (a) whether baseline exercise self-efficacy predicts PR attendance and change in functional exercise capacity and health status over PR, and (b) if exercise self-efficacy changes with PR. Fifty-eight out of 64 patients with COPD completed PR and assessments of exercise self-efficacy (task, coping, scheduling), the 6-minute walk test (6MWT), and St. George's Respiratory Questionnaire (SGRQ) at the beginning and end of PR. Analyses were conducted to predict attendance, and change in 6MWT and SGRQ, while controlling for baseline demographic and clinical indicators. Change in 6MWT, SGRQ, and self-efficacy with PR was also examined. Clinically significant increases in the 6MWT and SGRQ were achieved with PR. Stronger task self-efficacy predicted better attendance, while stronger coping self-efficacy predicted greater 6MWT improvement. No variables predicted SGRQ change. Scheduling self-efficacy significantly improved with PR, whereas task and coping self-efficacy did not. Baseline exercise self-efficacy appears to be a determinant of rehabilitation attendance and functional exercise improvement with PR. Clinicians should evaluate and target exercise self-efficacy to maximize adherence and health outcome improvement with PR. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    A new oxacephem antibiotic, flomoxef sodium (FMOX, 6315-S), was studied for its clinical efficacy in the field of pediatrics. The treated patients were infants and children ranging from 6 months to 14 years old suffering from bacterial pneumonia in 3 cases, acute tonsillitis in 2 cases, acute enterocolitis in 2 cases, and cellulitis and urinary tract infection in 1 case each, a total of 9 cases. FMOX was administered at (levels of) 57-150 mg/kg in daily dose with durations of treatment ranging from 5 to 18 days. Clinical efficacies of good or excellent results were obtained in all cases (excellent in 4, good in 5). As an adverse reaction, eosinophilia was observed in 1 patient. This elevation is, however, normalized with the cessation of the treatment.

    A meta-analysis was carried out of clinical trials published between 1987 and 2001 in respect of the clinical pharmacology and safety as well as the diagnostic efficacy of gadolinium-DTPA (Gd-DTPA) for direct intra-articular injection before MRI examination.Design. Scientific papers (clinical, postmortem and experimental studies) and information from the manufacturer regarding intra-articular injection of Gd-DTPA that addressed questions of mode of action, optimal concentration and dose, elimination and safety were reviewed. Clinical studies were classified according to their study design. The sensitivity, specificity and accuracy of MR arthrography (MRA) were compared with a ''gold standard'' (arthroscopy, arthrotomy) and other radiological evidence for different joints.Results. Fifty-two clinical studies of the overall 112 studies addressed aspects of diagnostic efficacy of MRA in patients or in healthy volunteers. The shoulder was the most assessed joint (29 of 52 studies). Good (>80%) or even excellent (90-100%) sensitivity, specificity and accuracy were found for MRA in most indications, especially for the shoulder and knee joints and induced extension of rotator cuff lesions, labrum abnormalities and postoperative meniscal tears. Two millimoles per liter has proven to be the best concentration for intra-articular administration of Gd-DTPA. After passive complete diffusion from the joint within 6-24 h, complete and rapid renal elimination takes place after intra-articular injection. Local safety proved to be excellent after intra-articular administration of Gd-DTPA. Regarding systemic tolerance almost no side effects have been reported, but the same safety considerations apply for intra-articular administration of Gd-DTPA as for intravenous injection.Conclusions. The diagnostic efficacy of intra-articular MRA in most clinical conditions affecting major joints is greater than that of plain MRI. In some diagnostic problems MRA achieves almost the same

    One hundred and seventy one neonates were treated with flomoxef (FMOX) and the clinical efficacy and safety were evaluated. The ages of the patients ranged from 0 to 28 days, and their body weights from 450 to 4300 g. Dose levels were 12.4 to 24.9 mg/kg every 8 or 12 hours for 1 to 10 days. Fifty two patients who responded to the FMOX treatment included 5 neonates with sepsis, 17 with suspected sepsis, 9 with urinary tract infections, 12 with pneumonia, 8 with intrauterine infections, and 1 with omphalitis. The other neonates could not be retrospectively diagnosed as bacterial infections. Of 52 patients, clinical results were excellent in 15, good in 34, fair in 1, and poor in 2. And the FMOX treatment was effective in 13 out of 14 patients in which causative bacteria were identified. The drug was well tolerated, but 6 neonates out of 33 over 5 days old had diarrhea. From these results, empiric treatment with FMOX against neonatal bacterial infection was as clinically useful as that of combination with ampicillin and gentamicin or cefotaxime and ampicillin in our neonatal intensive care unit. But, as this study did not include neonate with meningitis, efficacy to meningitis was not evaluated.

    The accuracy of self-assessment has been questioned in studies comparing physicians' self-assessments to observed assessments; however, none of these studies used self-efficacy as a method for self-assessment. The aim of the study was to investigate how medical students' perceived self-efficacy of specific communication skills corresponds to the evaluation of simulated patients and observers. All of the medical students who signed up for an Objective Structured Clinical Examination (OSCE) were included. As a part of the OSCE, the student performance in the "parent-physician interaction" was evaluated by a simulated patient and an observer at one of the stations. After the examination the students were asked to assess their self-efficacy according to the same specific communication skills. The Calgary Cambridge Observation Guide formed the basis for the outcome measures used in the questionnaires. A total of 12 items was rated on a Likert scale from 1-5 (strongly disagree to strongly agree). We used extended Rasch models for comparisons between the groups of responses of the questionnaires. Comparisons of groups were conducted on dichotomized responses. Eighty-four students participated in the examination, 87% (73/84) of whom responded to the questionnaire. The response rate for the simulated patients and the observers was 100%. Significantly more items were scored in the highest categories (4 and 5) by the observers and simulated patients compared to the students (observers versus students: -0.23; SE:0.112; p=0.002 and patients versus students:0.177; SE:0.109; p=0.037). When analysing the items individually, a statistically significant difference only existed for two items. This study showed that students scored their communication skills lower compared to observers or simulated patients. The differences were driven by only 2 of 12 items. The results in this study indicate that self-efficacy based on the Calgary Cambridge Observation guide seems to be a reliable

    Spinal cord stimulation (SCS) is a minimally invasive therapy used for the treatment of chronic neuropathic pain. SCS is a safe and effective alternative to medications such as opioids, and multiple randomized controlled studies have demonstrated efficacy for difficult-to-treat neuropathic conditions such as failed back surgery syndrome. Conventional SCS is believed mediate pain relief via activation of dorsal column Aβ fibers, resulting in variable effects on sensory and pain thresholds, and measurable alterations in higher order cortical processing. Although potentiation of inhibition, as suggested by Wall and Melzack's gate control theory, continues to be the leading explanatory model, other segmental and supraspinal mechanisms have been described. Novel, non-standard, stimulation waveforms such as high-frequency and burst have been shown in some studies to be clinically superior to conventional SCS, however their mechanisms of action remain to be determined. Additional studies are needed, both mechanistic and clinical, to better understand optimal stimulation strategies for different neuropathic conditions, improve patient selection and optimize efficacy. © 2018 World Institute of Pain.

    To evaluate in a comparative manner the safety and efficacy of 1.0% sodium-Hyaluronate used during capsulorhexis and intraocular lens (IOL) implantation in phacoemulsification surgery. 1.0% sodium-Hyaluronate, which is commonly used as one of the ophthalmic viscoelastic devices, was compared to intraocular irrigating solution, which can bring up these effects. In addition, the effect of both methods on occurring corneal endothelial cell (CEC) loss was investigated. Each group comprised 19 eyes. The mean preoperative CEC density was 2525.68 ± 181.85 in Group H and 2514.16 ± 174.59 in Group V; no statistically significant difference was found between the groups (p > 0.05). Preoperative and postoperative first and twelfth week CEC densities were 2438.21 ± 198.12 (p  0.05). Although it was found that there was no statistically difference in terms of preventing CEC loss between 1.0% sodium-Hyaluronate and the irrigation method during phacoemulsification, it was observed clinically that 1.0% sodium-hyaluronate can make the procedure easy, safer, very helpful, especially for understanding phacoemulsification.

    2018-06-01

    Joint modelling of longitudinal biomarker and event-time processes has gained its popularity in recent years as they yield more accurate and precise estimates. Considering this modelling framework, a new methodology for evaluating the time-dependent efficacy of a longitudinal biomarker for clinical endpoint is proposed in this article. In particular, the proposed model assesses how well longitudinally repeated measurements of a biomarker over various time periods (0,t) distinguish between individuals who developed the disease by time t and individuals who remain disease-free beyond time t. The receiver operating characteristic curve is used to provide the corresponding efficacy summaries at various t based on the association between longitudinal biomarker trajectory and risk of clinical endpoint prior to each time point. The model also allows detecting the time period over which a biomarker should be monitored for its best discriminatory value. The proposed approach is evaluated through simulation and illustrated on the motivating dataset from a prospective observational study of biomarkers to diagnose the onset of sepsis.

    To comparatively evaluate the antimicrobial efficacy of freshly prepared electrolyzed oxidizing water (EOW) with that of 2.4% glutaraldehyde (GA) and 1% sodium hypochlorite (SH) on clinically derived poly vinyl siloxane (PVS) impressions. Four clinically derived PVS impressions each were obtained from 10 subjects. One impression from each subject was randomly kept as control (group I), without disinfection. The remaining three impressions were randomly disinfected by immersion in either 2.4% GA (group II), 1% SH (group III), or freshly prepared EOW (group IV). The samples were subjected to microbial culture individually on brain heart infusion (BHI) agar medium. The organisms isolated were confirmed by visual examination and gram staining. Mean colony forming units (CFU) were counted, log 10 reduction obtained and compared. Data were statistically analyzed using one-way ANOVA, followed by multiple comparisons using Tukey-HSD post hoc tests (p < 0.05). Streptococci, Staphylococci, Pseudomonas, Candida, Proteus, Klebsiella, and E. coli were isolated from all impressions including the controls, except those disinfected by EOW. All three disinfectants showed significant reduction in CFU and log 10 reduction values as compared to the controls. EOW showed significantly higher reduction in log 10 values compared to GA and SH, whereas GA and SH showed similar reductions. EOW, GA, and SH showed kill rates of 100%, 99.60%, and 99.82%, respectively. EOW showed significant antimicrobial efficacy as evidenced by reduction in log 10 values when used as an immersion disinfectant for PVS impressions when compared with the results obtained using GA and SH. These results need further investigation. EOW shows high antimicrobial efficacy when used as an immersion disinfectant as compared to GA and SH for clinically derived PVS impressions. © 2016 by the American College of Prosthodontists.

    A good control of bacterial plaque is an essential factor for the success of periodontal therapy, therefore it is the main objective that the clinician together with the patient must get to have a healthy periodontium. The plaque control with mouthwashes is the most important home therapy as it helps to reduce the formation of plaque between the mechanical removal with a toothbrush. Authors analyzed the clinical data from a trial carried out with 3 different mouthwashes containing 0.2% Chlorhexidine (CHX). In addition, the ADS (Anti Discoloration System - Curaden Healthcare) was tested in comparison with the other mouthwashes without this system. We tested antiplaque activity showed by 3 of the most commercialized mouthwashes, moreover, we tested the ability in reducing the dental staining related to the oral assumption of Chlorhexidine. Our results demonstrated the clinical efficacy of the 3 mouthwashes with CHX. Particularly performing was the anti discoloration system (Curaden Healthcare), with a clinical detection of dental stainings significantly less than the others tested. This study demonstrated the clinical efficacy of ADS system in the reduction of tooth staining, without a loss of antiplaque activity with respect to the competing mouthwashes containing CHX.

This review aimed to evaluate and compare the efficacy of different pharmacist based interventions on clinical outcomes of type 2 diabetes patients.Methods: A systematic search was conducted across five databases from date of database inception to September 2017. All randomized clinical trials evaluating the efficacy of pharmacist based interventions on type 2 diabetes patients were included for network meta-analysis (NMA. The protocol is available with PROSPERO (CRD42017078854.Results: A total of 43 studies, involving 6259 type 2 diabetes patients, were included. NMA demonstrated that all interventions significantly lowered glycosylated hemoglobin (HbA1c levels compared to usual care, but there was no statistical evidence from this study that one intervention was significantly better than the other for reducing HbA1c levels. Pharmacist based diabetes education plus pharmaceutical care showed maximum efficacy for reducing HbA1c levels [−0.86, 95% CI −0.983, −0.727; p < 0.001]. Pharmacist based diabetes education plus pharmaceutical care was observed to be statistically significant in lowering levels of systolic blood pressure [−4.94; 95%CI −8.65, −1.23] and triglycerides levels [−0.26, 95%CI −0.51, −0.01], as compared to the interventions which involved diabetes education by pharmacist, and for body mass index (BMI [−0.57; 95%CI −1.25, −0.12] in comparison to diabetes education by health care team involving pharmacist as member.Conclusion: The findings of this review demonstrate that all interventions had a significantly positive effect on HbA1c, but there was no statistical evidence from this study that one intervention was significantly better than the other for achieving glycemic control.Pharmacist based diabetes education plus pharmaceutical care showed maximum efficacy on HbA1c and

    Rufinamide is a triazole derivative structurally unrelated to other antiepileptic drugs that is indicated for the adjunctive treatment of seizures associated with Lennox-Gastaut syndrome (LGS) in patients aged ≥4 years. Originally granted orphan drug status, marketing authorisation was obtained on the basis of a randomised, double-blind, placebo-controlled trial conducted in 138 LGS patients. An open-label extension study subsequently demonstrated that rufinamide's efficacy and tolerability were maintained over the longer term (median duration of treatment, 432 days). Recently published reports from Europe and the United States have described the use of adjunctive rufinamide to treat LGS in clinical practice. These data complement the clinical trial results, by providing information on the efficacy and tolerability of rufinamide when used on an individualised basis in real-world practice, under less tightly restricted conditions in terms of patient population and dosing strategies. A comparison of the data reveals that a "lower and slower" dosing strategy tends to be adopted in clinical practice, in comparison with the clinical trial, which does not appear to compromise efficacy, but may provide improvements in tolerability. Individual case reports provide additional valuable information on how rufinamide is being used to treat different seizure types associated with LGS. Since clinical experience with rufinamide is currently at an early stage, there are still unanswered questions relating to its use, and it is likely that its place in the adjunctive treatment of LGS will evolve as further data emerge.

    Background Laparoscopic ovarian drilling (LOD) is an alternative method to induce ovulation in polycystic ovary syndrome (PCOS) patients with clomiphene citrate (CC) resistant instead of gonadotropins. This study aimed to compare the efficacy of unilateral LOD (ULOD) versus bilateral LOD (BLOD) in CC resistance PCOS patients in terms of ovulation and pregnancy rates. Materials and Methods In a prospective randomized clinical trial study, we included 100 PCOS patients with CC resistance attending to Al-Zahra Hospital in Rasht, Guilan Province, Iran, from June 2011 to July 2012. Patients were randomly divided into two ULOD and BLOD groups with equal numbers. The clinical and biochemical responses on ovulation and pregnancy rates were assessed over a 6-month follow-up period. Results Differences in baseline characteristics of patients between two groups prior to laparoscopy were not significant (p>0.05). There were no significant differences between the two groups in terms of clinical and biochemical responses, spontaneous menstruation (66.1 vs. 71.1%), spontaneous ovulation rate (60 vs. 64.4%), and pregnancy rate (33.1 vs. 40%) (p>0.05). Following drilling, there was a significant decrease in mean serum concentrations of luteinizing hormone (LH) (p=0.001) and testosterone (p=0.001) in both the groups. Mean decrease in serum LH (p=0.322) and testosterone concentrations (p=0.079) were not statistically significant between two groups. Mean serum level of follicle stimulating hormone (FSH) did not change significantly in two groups after LOD (p>0.05). Conclusion Based on results of this study, ULOD seems to be equally efficacious as BLOD in terms of ovulation and pregnancy rates (Registration Number: IRCT138903291306N2). PMID:25918587

    To compare the clinical efficacy between salvage antimicrobial regimen consisting of tigecycline plus extended-infusion imipenem/cilastatin (TIC) and regimen of sulbactam plus imipenem/cilastatin (SIC) for patients with ventilator-associated pneumonia and pneumonic bacteremia due to extensively drug-resistant (XDR) Acinetobacter baumannii (Ab) isolates, and determine the correlation of results of in vitro tigecycline-imipenem synergy test with clinical efficacy. The comparative survey was conducted at a medical center in Taiwan in 2013. Patients comprising the TIC group (n = 28) received tigecycline plus extended-infusion imipenem/cilastatin following unresponsiveness to 3-day sulbactam-imipenem/cilastatin therapy, and those in the SIC group (n = 56) received sulbactam-imipenem/cilastatin throughout the course. Univariate and multivariate analyses were applied to explore 30-day case-fatality independent predictors. Additionally, the checkerboard test and time-kill analysis were performed for the bloodstream XDR-Ab isolates from patients in the TIC group, and molecular characterization was done for the bloodstream XDR-Ab strains of all patients. We found that the TIC scheme has a significant benefit on improving patients' survival status (the mortality rate of TIC and SIC group patients was 14.3% and 64.3%, respectively), corresponding well with in vitro synergy or additivity results by the checkerboard test. Twenty TIC group cases had monomicrobial XDR-Ab cultured from tracheal aspirates after 10 days of tigecycline-imipenem/cilastatin therapy, but none developed subsequent pneumonia. However, breakthrough primary Burkholderia cepacia (n = 3) and Pseudomonas aeruginosa (n = 1) bacteremias were attributed to four TIC case fatalities. Shock, SIC regimen usage, and development of breakthrough bacteremia were independent predictors of 30-day in-hospital mortality. Although the TIC regimen showed good efficacy, its value regarding managing XDR-Ab ventilator

  20. Multiple comparisons in drug efficacy studies: scientific or marketing principles?

    When researchers design an experiment to compare a given medication to another medication, a behavioral therapy, or a placebo, the experiment often involves numerous comparisons. For instance, there may be several different evaluation methods, raters, and time points. Although scientifically justified, such comparisons can be abused in the interests of drug marketing. This article provides two recent examples of such questionable practices. The first involves the case of the arthritis drug celecoxib (Celebrex), where the study lasted 12 months but the authors only presented 6 months of data. The second case involves the NIMH Multimodal Treatment Study (MTA) study evaluating the efficacy of stimulant medication for attention-deficit hyperactivity disorder where ratings made by several groups are reported in contradictory fashion. The MTA authors have not clarified the confusion, at least in print, suggesting that the actual findings of the study may have played little role in the authors' reported conclusions.

    Large tooth substance losses are frequent in posterior teeth because of primary caries or aging restorations. Inlays and onlays are often the minimal invasive solution in such cases, but the efficacy of the composite and ceramic materials used is unknown. We performed a systematic review of randomized controlled trials comparing the efficacy of composite and ceramic inlays or onlays. MEDLINE, Embase and the Cochrane Central Register of Controlled Trials were searched without any restriction on date or language, as were references of eligible studies and ClinicalTrials.gov. Eligible studies were randomized trials comparing the clinical efficacy of composite to ceramic inlays or onlays in adults with any clinical outcome for at least 6 months. From 172 records identified, we examined reports of 2 randomized controlled trials involving 138 inlays (no onlays evaluated) in 80 patients and exhibiting a high-risk of bias. Outcomes were clinical scores and major failures. The 3-year overall failure risk ratio was 2 [0.38-10.55] in favor of ceramic inlays although not statistically significant. The reported clinical scores (United States Public Health Services and Californian Dental Association) showed considerable heterogeneity between trials and could not be combined. We have very limited evidence that ceramics perform better than composite material for inlays in the short term. However, this result may not be valid in the long term, and other trials are needed. Trials should follow Fédération dentaire internationale recommendations and enhance their methodology. Trials comparing composite and ceramic onlays are needed.

    Autologous hematopoietic stem cell transplantation (HSCT) of gene-modified cells is an alternative to enzyme replacement therapy (ERT) and allogeneic HSCT that has shown clinical benefit for adenosine deaminase-deficient (ADA-deficient) SCID when combined with reduced intensity conditioning (RIC) and ERT cessation. Clinical safety and therapeutic efficacy were evaluated in a phase II study. Ten subjects with confirmed ADA-deficient SCID and no available matched sibling or family donor were enrolled between 2009 and 2012 and received transplantation with autologous hematopoietic CD34+ cells that were modified with the human ADA cDNA (MND-ADA) γ-retroviral vector after conditioning with busulfan (90 mg/m2) and ERT cessation. Subjects were followed from 33 to 84 months at the time of data analysis. Safety of the procedure was assessed by recording the number of adverse events. Efficacy was assessed by measuring engraftment of gene-modified hematopoietic stem/progenitor cells, ADA gene expression, and immune reconstitution. With the exception of the oldest subject (15 years old at enrollment), all subjects remained off ERT with normalized peripheral blood mononuclear cell (PBMC) ADA activity, improved lymphocyte numbers, and normal proliferative responses to mitogens. Three of nine subjects were able to discontinue intravenous immunoglobulin replacement therapy. The MND-ADA vector was persistently detected in PBMCs (vector copy number [VCN] = 0.1-2.6) and granulocytes (VCN = 0.01-0.3) through the most recent visits at the time of this writing. No patient has developed a leukoproliferative disorder or other vector-related clinical complication since transplant. These results demonstrate clinical therapeutic efficacy from gene therapy for ADA-deficient SCID, with an excellent clinical safety profile. ClinicalTrials.gov NCT00794508.

    The purpose of this study was to investigate the efficacy and safety of the administration of retinol palmitate (VApal) ophthalmic solution (500 IU/mL) for the treatment of patients with dry eye. This study included 66 patients with dry eye. After a 2-week washout period, patients were randomized (1:1) into either a VApal ophthalmic solution or a placebo group, and a single drop of either solution was administered six times daily for 4 weeks. Efficacy measures were 12 subjective symptoms, rose bengal (RB) and fluorescein staining scores, tear film breakup time, and tear secretion. Safety measures included clinical blood and urine analyses and adverse event recordings. In comparisons of the two groups, the mean change in RB staining score from baseline was significantly lower in the VApal group at 2 and 4 weeks ( P ophthalmic solution (500 IU/mL) is safe and effective for the treatment of patients with dry eye.

    2013-01-01

    Full Text Available Objective. To explore the existing scientific information regarding safe needling depth of acupuncture points and the needling depth of clinical efficacy. Methods. We searched the PubMed, EMBASE, Cochrane, Allied and Complementary Medicine (AMED, The National Center for Complementary and Alternative Medicine (NCCAM, and China National Knowledge Infrastructure (CNKI databases to identify relevant monographs and related references from 1991 to 2013. Chinese journals and theses/dissertations were hand searched. Results. 47 studies were recruited and divided into 6 groups by measuring tools, that is, MRI, in vivo evaluation, CT, ultrasound, dissected specimen of cadavers, and another group with clinical efficacy. Each research was analyzed for study design, definition of safe depth, and factors that would affect the measured depths. Depths of clinical efficacy were discussed from the perspective of de-qi and other clinical observations. Conclusions. Great inconsistency in depth of each point measured from different subject groups and tools exists. The definition of safe depth should be established through standardization. There is also lack of researches to compare the clinical efficacy. A well-designed clinical trial selecting proper measuring tools to decide the actual and advisable needling depth for each point, to avoid adverse effects or complications and promote optimal clinical efficacy, is a top priority.

  6. Efficacy Coefficients Determined Using Nail Permeability and Antifungal Activity in Keratin-Containing Media Are Useful for Predicting Clinical Efficacies of Topical Drugs for Onychomycosis.

    Full Text Available Onychomycosis is difficult to treat topically due to the deep location of the infection under the densely keratinized nail plate. In order to obtain an in vitro index that is relevant to the clinical efficacy of topical anti-onychomycosis drugs, we profiled five topical drugs: amorolfine, ciclopirox, efinaconazole, luliconazole, and terbinafine, for their nail permeabilities, keratin affinities, and anti-dermatophytic activities in the presence of keratin. Efinaconazole and ciclopirox permeated full-thickness human nails more deeply than luliconazole. Amorolfine and terbinafine did not show any detectable permeation. The free-drug concentration of efinaconazole in a 5% human nail keratin suspension was 24.9%, which was significantly higher than those of the other drugs (1.1-3.9%. Additionally, efinaconazole was released from human nail keratin at a greater proportion than the other drugs. The MICs of the five drugs for Trichophyton rubrum were determined at various concentrations of keratin (0-20% in RPMI 1640 medium. The MICs of ciclopirox were not affected by keratin, whereas those of efinaconazole were slightly increased and those of luliconazole and terbinafine were markedly increased in the presence of 20% keratin. Efficacy coefficients were calculated using the nail permeation flux and MIC in media without or with keratin. Efinaconazole showed the highest efficacy coefficient, which was determined using MIC in media with keratin. The order of efficacy coefficients determined using MIC in keratin-containing media rather than keratin-free media was consistent with that of complete cure rates in previously reported clinical trials. The present study revealed that efficacy coefficients determined using MIC in keratin-containing media are useful for predicting the clinical efficacies of topical drugs. In order to be more effective, topical drugs have to possess higher efficacy coefficients.

    Social comparison theory is relevant for learning in general. In a clinical context, we examined four hypotheses concerning: preferred other to compare with, preferred direction of comparison, response to social comparison and influence of personal social comparison orientation (SCO). To investigate the relevance of social comparison for clinical workplace learning. Students (n = 437) from nine different hospitals completed two questionnaires measuring their SCO and the direction of and response to their comparisons. t-tests were used to analyse the data. Students substantially did compare. They preferred to compare with peer students more than with residents or staff, and with peers doing better more than with peers doing worse. Their response to social comparison was more often stimulating for learning than discouraging. Students high in SCO reported a stronger stimulating and discouraging response to their comparisons than students low in SCO. Social comparison does play a role in clinical workplace learning. The mainly stimulating response to social comparison indicates a positive learning influence. The preferred comparison with peers emphasizes the role of peers in the learning process. Further research should focus on student comparison behaviour and on situations that strengthen the positive effects of social comparison and reduce the negative or obstructing ones.

    Full Text Available Katie Witkiewitz, Kimber Saville, Kacie HamreusDepartment of Psychology, Washington State University Vancouver, Vancouver, WA, USAAbstract: Acamprosate, or N-acetyl homotaurine, is an N-methyl-D-aspartate receptor modulator approved by the Food and Drug Administration (FDA as a pharmacological treatment for alcohol dependence. The exact mechanism of action of acamprosate is still under investigation, but the drug appears to work by promoting a balance between the excitatory and inhibitory neurotransmitters, glutamate and gamma-aminobutyric acid, respectively, and it may help individuals with alcohol dependence by reducing withdrawal-associated distress. Acamprosate has low bioavailability, but also has an excellent tolerability and safety profile. In comparison with naltrexone and disulfiram, which are the other FDA-approved treatments for alcohol dependence, acamprosate is unique in that it is not metabolized by the liver and is also not impacted by alcohol use, so can be administered to patients with hepatitis or liver disease (a common comorbid condition among individuals with alcohol dependence and to patients who continue drinking alcohol. Acamprosate has demonstrated its efficacy in more than 25 placebo-controlled, double-blind trials for individuals with alcohol dependence, and has generally been found to be more efficacious than placebo in significantly reducing the risk of returning to any drinking and increasing the cumulative duration of abstinence. However, acamprosate appears to be no more efficacious than placebo in reducing heavy drinking days. Numerous trials have found that acamprosate is not significantly more efficacious than naltrexone or disulfiram, and the efficacy of acamprosate does not appear to be improved by combining acamprosate with other active medications (eg, naltrexone or with psychosocial treatment (eg, cognitive-behavioral therapy. In this review, we present the data on acamprosate, including its pharmacology

    Supervision is a primary instructional vehicle for genetic counseling student clinical training. Approximately two-thirds of genetic counselors report teaching and education roles, which include supervisory roles. Recently, Eubanks Higgins and colleagues published the first comprehensive list of empirically-derived genetic counseling supervisor competencies. Studies have yet to evaluate whether supervisors possess these competencies and whether their competencies differ as a function of experience. This study investigated three research questions: (1) What are genetic counselor supervisors' perceptions of their capabilities (self-efficacy) for a select group of supervisor competencies?, (2) Are there differences in self-efficacy as a function of their supervision experience or their genetic counseling experience, and 3) What training methods do they use and prefer to develop supervision skills? One-hundred thirty-one genetic counselor supervisors completed an anonymous online survey assessing demographics, self-efficacy (self-perceived capability) for 12 goal setting and 16 feedback competencies (Scale: 0-100), competencies that are personally challenging, and supervision training experiences and preferences (open-ended). A MANOVA revealed significant positive effects of supervision experience but not genetic counseling experience on participants' self-efficacy. Although mean self-efficacy ratings were high (>83.7), participant comments revealed several challenging competencies (e.g., incorporating student's report of feedback from previous supervisors into goal setting, and providing feedback about student behavior rather than personal traits). Commonly preferred supervision training methods included consultation with colleagues, peer discussion, and workshops/seminars.

    Full Text Available The paper analyzes two matching-adjusted indirect comparison-based investigations of the efficacy of adalimumab (ADA and secukinumab (SCM in active ankylosing spondylitis, which have been recently reported at the EULAR Congress (London, 2016. One study sponsored by AbbVie was conducted to determine the short-term (16-week comparative clinical and economic efficacy of the test drugs and the other was supported by Novartis to reveal long-term (52-week, only clinical efficacy. Both studies have shown that the short-term efficacy ofADAand SCM is practically similar; however, the latter has a better long-term clinical efficacy. A pharmacoeconomic analysis of both drugs used during the first 12 weeks has demonstrated some advantage ofADA.

    Cystic echinococcosis is a chronic, complex, and still neglected disease. Although albendazole has demonstrated efficacy, only about one-third of patients experience complete remission or cure and 30-50% of treated patients develop some evidence of a therapeutic response. Different strategies have been developed in order to improve the albendazole water solubility and dissolution rate. The aim of the current work was to investigate the chemoprophylactic and clinical efficacy of an albendazole:poloxamer 188 solid dispersion formulation on mice infected with Echinococcus granulosus metacestodes. Albendazole formulated as solid dispersion had greater chemoprophylactic and clinical efficacy than albendazole alone. The improved in therapeutic efficacy could be a consequence of the increase in the systemic availability of albendazole sulfoxide. The work reported here demonstrates that in vivo treatment with albendazole:poloxamer 188 impairs the development of the hydatid cysts. This new pharmacotechnically based strategy could be a suitable alternative for treating cystic echinococcosis in humans. Copyright © 2014 Elsevier B.V. All rights reserved.

    Intercessory prayers for health or healing are requests to an object of worship for the preservation or restoration of health. There has been a recent proliferation of clinical trials that compare the health outcome of a group of prayed-for patients with that of controls, to test the efficacy of intercessory prayer. In this essay, the author defines the concept of intercessory prayer, contrasts it with other forms of prayer, and reviews the literature concerning clinical trials of its efficacy. The arguments put forward in favor of conducting such trials and those against are described and the reader is invited to consider their relative merits. The author concludes by discussing the potential power of faith in healing, reviewing the philosophical basis and pitfalls of clinical trials of intercessory prayer, and urging readers to weigh the arguments for and against such trials in academic medicine.

    The clinical dehydration scale (CDS) is a quick, easy-to-use tool with 4 clinical items and a score of 1-8 that serves to classify dehydration in children with gastroenteritis as no, some or moderate/severe dehydration. Studies validating the CDS (Friedman JN) with a comparison group remain elusive. We hypothesized that the CDS correlates with a wide spectrum of established markers of dehydration, making it an appropriate and easy-to-use clinical tool. This study was designed as a prospective double-cohort trial in a single tertiary care center. Children with diarrhea and vomiting, who clinically required intravenous fluids for rehydration, were compared with minor trauma patients who required intravenous needling for conscious sedation. We compared the CDS with clinical and urinary markers (urinary electrolytes, proteins, ratios and fractional excretions) for dehydration in both groups using receiver operating characteristic (ROC) curves to determine the area under the curve (AUC). We enrolled 73 children (male = 36) in the dehydration group and 143 (male = 105) in the comparison group. Median age was 32 months (range 3-214) in the dehydration and 96 months (range 2.6-214 months, p dehydration group and 0 in the comparison group (p dehydrated group: difference in heart rate, diastolic blood pressure, urine sodium/potassium ratio, urine sodium, fractional sodium excretion, serum bicarbonate, and creatinine measurements. The best markers for dehydration were urine Na and serum bicarbonate (ROC AUC = 0.798 and 0.821, respectively). CDS was most closely correlated with serum bicarbonate (Pearson r = -0.3696, p = 0.002). Although serum bicarbonate is not the gold standard for dehydration, this study provides further evidence for the usefulness of the CDS as a dehydration marker in children.

    This meta-analysis aimed to evaluate the efficacy of trimetazidine in combination with other anti-anginal drugs versus other anti-anginal drugs in the treatment of stable angina pectoris (SAP). Randomized controlled trials (RCTs) published in English and Chinese were retrieved from computerized databases: Embase, PubMed, and CNKI. Primary outcomes consist of clinical parameters (numbers of weekly angina attacks and nitroglycerin use) and ergometric parameters (time to 1mm ST-segment depression, and total work (in Mets) and exercise duration (in seconds) at peak exercise) in stable angina pectoris treated by trimetazidine or not. The quality of studies was evaluated using Jadad score. Data analysis of 13 studies was performed using Stata 12.0 software. Results showed that treatment of trimetazidine and other anti-anginal drugs was associated with a smaller weekly mean number of angina attacks (WMD=-0.95, 95%CI: -1.30 to -0.61, Z=5.39, Pangina pectoris. Sensitivity analysis was performed. Sub-group analysis showed that treatment duration was not a significant moderator and patients treated within 8 weeks and above 12 weeks had no difference in the outcomes addressed in this meta-analysis. No publish bias was detected. This meta-analysis confirms the efficacy of trimetazidine in the treatment of stable angina pectoris, in comparison with conventional antianginal agents, regardless of treatment duration.

    We developed the novel silk fibroin-based bilayered wound dressing for the treatment of partial thickness wounds. And it showed relevant characteristics and accelerated the healing of full-thickness wounds in a rat model. This study is the clinical evaluation of the bilayered wound dressing to confirm its safety and efficacy for the treatment of split-thickness skin donor sites. The safety test was performed using a patch model and no evidence of marked and severe cutaneous reactions was found. The efficacy test of the bilayered wound dressing was conducted on 23 patients with 30 split-thickness skin graft donor sites to evaluate healing time, pain score, skin barrier function, and systemic reaction in comparison to Bactigras. We found that the healing time of donor site wounds treated with the bilayered wound dressing (11 ± 6 days) was significantly faster than those treated with Bactigras (14 ± 6 days) (p = 10−6). The wound sites treated with the bilayered wound dressing showed significantly less pain and more rapid skin functional barrier recovery than those treated with Bactigras (p = 10−5). Therefore, these results confirmed the clinical safety and efficacy of the bilayered wound dressing for the treatment of split-thickness skin graft donor sites. PMID:26221170

    Full Text Available Background. We aimed to evaluate the efficacy of various diagnostic tools such as computerized tomography (CT, small bowel follow-through (SBFT, and capsule endoscopy (CE in diagnosing small bowel tumors (SBTs. Additionally, we aimed to evaluate the clinical features of SBTs missed by CE. Methods. We retrospectively studied 79 patients with histologically proven SBT. Clinical data were analyzed with particular attention to the efficacy of CT, SBFT, and CE in detecting SBT preoperatively. We also analyzed the clinical features of SBTs missed by CE. Results. The most common symptoms of SBT were bleeding (43% and abdominal pain (13.9%. Diagnostic yields were as follows: CT detected 55.8% of proven SBTs; SBFT, 46.1%; and CE, 83.3%. The sensitivity for detecting SBTs was 40.4% for CT, 43.9% for SBFT, and 79.6% for CE. Two patients with nondiagnostic but suspicious findings on CE and seven patients with negative findings on CE were eventually found to have SBT. These nine patients were eventually diagnosed with gastrointestinal stromal tumor (4, small polyps (3, inflammatory fibroid polyp (1, and adenocarcinoma (1. These tumors were located in the proximal jejunum (5, middle jejunum (1, distal jejunum (1, and proximal ileum (1. Conclusion. CE is more efficacious than CT or SBFT for detecting SBTs. However, significant tumors may go undetected with CE, particularly when located in the proximal jejunum.

    The present study aimed to compare the therapeutic efficacy of dimenhydrinate and piracetam in patients with vertigo. A blinded, parallel group, superiority, randomised clinical trial was carried out on patients who presented to the emergency department (ED) with vertigo. Healthy adult patients presenting to the ED with undifferentiated vertigo were included in the study. The efficacy of intravenous dimenhydrinate (100 mg) and intravenous piracetam (2000 mg) for reducing the intensity of vertigo was compared in two randomised treatment groups using a 10-point numeric rating scale (NRS). The determination of NRS scores was performed at presentation and at the 30th minute of presentation, after the study drug was implemented, both in immobile and ambulatory positions. The primary outcome variable was reduction in vertigo intensity documented on the NRS at the 30th minute after medication administration, analysed by intention to treat. A total of 94 patients were included in the randomisation (n=47 in both groups). The baseline NRS scores were 7.55±2.00 in the dimenhydrinate group and 8.19±1.79 in the piracetam group. The changes from baseline for dimenhydrinate and piracetam were 2.92±3.11 and 3.75±3.40 (difference -0.83 (95% CI -2.23 to 0.57)) in the immobile position and were 2.04±3.07 and 2.72±2.91 (difference -0.68 (95% CI -2.03 to 0.67)) in the ambulatory position. Rescue medication need was similar in both treatment groups (p=0.330), and only one adverse reaction was reported. We found no evidence of a difference between dimenhydrinate and piracetam in relieving the symptoms of vertigo. Clinical Trials Registration ID: NCT01890538.

    Objective: To investigate the efficacy and predictive value of clinical stage in non-surgical patients with esophageal cancer (EC). Methods: A retrospective study was conducted in 358 EC patients who underwent radical surgery in our hospital from April 2003 to October 2010 and who had preoperative work-up including endoscopic esophageal ultrasound (EUS), esophagoscopy, thoracic CT scans,and contrast esophagography and had detailed information on postoperative pathological stages. The predictive value of preoperative clinical T/N stage based on EUS + CT for postoperative pathological stage was analyzed. The disease free survival (DFS) and overall survival (OS) were analyzed according to the UICC TNM classification (2002/ 2009) and the clinical stage based on imaging findings. Results: The median follow-up was 47 months.A total of 305 (85.2%) of all patients were analyzed by clinical stage based on EUS + CT.Among them, the predictive value of clinical T stage for pathological T stage was 0-88.6%, highest (88.6%) for T1 stage and lowest for T4 stage. The predictive value of clinical N stage (N 0 /N1) was 62.5-100%. The significant differences in OS and DFS rates based on both 2002 and 2009 UICC TNM classifications were noted (P=0.000 and 0.000). There were significant differences in OS between stage groups, except the comparison between two stage Ⅳ patients and other groups, according to 2002 UICC TNM classification. There were usually insignificant differences in OS between stage groups, according to 2009 UICC TNM classification. For the 305 patients staged clinically based on EUS and CT according to 2002 UICC TNM classification, significant differences in OS and DFS rates were noted (P=0.000 and 0.000). Conclusions: Imaging modalities show good predictive value for N stage (N0/N1),even though they cannot accurately provide the number of metastatic lymph nodes. The clinical stage based on EUS + CT can effectively predict the prognosis of non-surgical EC patients

    Development of a new drug for the treatment of lung disease is a complex and time consuming process involving numerous disciplines of basic and applied sciences. During the 2015 Congress of the International Society for Aerosols in Medicine, a group of experts including aerosol scientists, physiologists, modelers, imagers, and clinicians participated in a workshop aiming at bridging the gap between basic research and clinical efficacy of inhaled drugs. This publication summarizes the current consensus on the topic. It begins with a short description of basic concepts of aerosol transport and a discussion on targeting strategies of inhaled aerosols to the lungs. It is followed by a description of both computational and biological lung models, and the use of imaging techniques to determine aerosol deposition distribution (ADD) in the lung. Finally, the importance of ADD to clinical efficacy is discussed. Several gaps were identified between basic science and clinical efficacy. One gap between scientific research aimed at predicting, controlling, and measuring ADD and the clinical use of inhaled aerosols is the considerable challenge of obtaining, in a single study, accurate information describing the optimal lung regions to be targeted, the effectiveness of targeting determined from ADD, and some measure of the drug's effectiveness. Other identified gaps were the language and methodology barriers that exist among disciplines, along with the significant regulatory hurdles that need to be overcome for novel drugs and/or therapies to reach the marketplace and benefit the patient. Despite these gaps, much progress has been made in recent years to improve clinical efficacy of inhaled drugs. Also, the recent efforts by many funding agencies and industry to support multidisciplinary networks including basic science researchers, R&D scientists, and clinicians will go a long way to further reduce the gap between science and clinical efficacy.

    Omalizumab is a subcutaneously administrated monoclonal anti-IgE antibody indicated in adults, adolescents and children 6 years of age and older with moderate to severe allergic asthma uncontrolled by conventional pharmacological treatments and sensitization to at least one perennial allergen. Area covered: This drug evaluation summarizes published data on pharmacokinetic and pharmacodynamic properties of omalizumab, on clinical efficacy and safety, including real-world evidence, and provides a medico-economic evaluation of the drug. Expert opinion: Omalizumab represents an efficient therapeutic option for the management of patients with uncontrolled moderate/severe allergic asthma. It provides a significant reduction in the asthma exacerbation rate with a steroid-sparing effect, an improvement in quality of life in adults and adolescents, despite a lack of evidence about its efficacy specifically in severe allergic asthma. Clinical trials have demonstrated its efficacy in the pediatric population but further real-life evidence is expected to better characterize long-term effects in this population. There is still some debate about the optimal treatment duration but, to date, it is recommended not to stop the treatment as cessation has resulted in symptom recurrence. Omalizumab is an expensive treatment, but a key therapeutic option when used for uncontrolled severe allergic asthma.

    The need to assess relative efficacy in the absence of comparative clinical trials is a problem that is often encountered in economic modeling. The use of matching adjusted indirect comparison (MAIC) in this situation has been suggested. We present the results of a MAIC used to evaluate the incremental benefit offered by adding simeprevir (SMV) to standard therapy in the treatment of patients infected with genotype 4 hepatitis C virus (HCV). Individual patient data for a single arm study evaluating the use of SMV with peginterferon alfa 2a + ribavirin (PR) in genotype 4 HCV were available (RESTORE study). A systematic literature review was used to identify studies of PR alone used in the same patient group. By applying the inclusion criteria for each study in turn to the RESTORE dataset and then applying the published MAIC covariate matching algorithm, a series of pseudosamples from RESTORE were generated. After assessment of the matching outcomes, the best matched comparisons were used to derive estimates of efficacy for SMV + PR in patients equivalent to those participating in the PR trial. Five potential comparator studies were identified. After applying the matching process, two emerged as offering the greatest equivalence with the generated RESTORE pseudosamples and were used to estimate SMV + PR efficacy, expressed as the percentage of patients achieving sustained viral response (SVR). In one comparison, SVR in the SMV + PR group was 85% versus 63% for PR alone. In the second comparison, the corresponding SVRs were 77% and 44% respectively. After matching for varying baseline characteristics, both comparisons of RESTORE versus studies of PR alone yielded a benefit for SMV + PR vs PR alone in genotype 4 HCV-infected patients. The incremental gain in SVR associated with use of SMV ranged from 22% to 33%. In the absence of direct comparative studies, the MAIC gives a better perspective than simple comparison of absolute SVR from individual

    Full Text Available We conducted a systematic literature review with indirect comparison of studies evaluating therapeutic efficacy and toxicity associated to visceral leishmaniasis (VL therapy among HIV infected individuals.The outcomes of interest were clinical and parasitological cure, mortality, and adverse events.PRISMA guidelines for systematic reviews and Cochrane manual were followed. Sources were MEDLINE, LILACS, EMBASE, Web of Knowledge databases and manual search of references from evaluated studies. We included all studies reporting outcomes after VL treatment, regardless of their design. Study quality was evaluated systematically by using the Newcastle-Ottawa Scale (NOS for assessing the quality of nonrandomized studies in meta-analyses. Comprehensive Meta-Analysis software v.2.2.048 was used to perform one-group meta-analysis of study arms with the same drug to estimate global rates of success and adverse events with each drug. These estimates were used, when possible, to indirectly compare treatment options, adjusted for CD4 count. Direct comparison was pooled when available.Seventeen studies reporting five treatment regimens and outcome of 920 VL episodes occurring in HIV infected individuals were included. The main outstanding difference in outcome among the treatment regimens was observed in mortality rate: it was around 3 times higher with high-dose antimony use (18.4%, CI 95% 13.3-25%, indirectly compared to lipid formulations of amphotericin B treatment (6.1%, CI 95% 3.9-9.4%. It was observed, also by indirect comparison, higher rates of clinical improvement in study arms using amphotericin B than in study arms using pentavalent antimonial therapy (Sb(v. The parasitological cure, an outcome that presented some degree of risk of selection and verification bias, had rates that varied widely within the same treatment arm, with high heterogeneity, hampering any formal comparison among drugs. One direct comparison of amphotericin and antimoniate was

    Numerous reports have described the superior properties of nanoparticles and their diverse range of applications. Issues of toxicity, workplace safety and environmental impact have also been a concern. Here we show a theoretical comparison of how the size of titanium dioxide nanoparticles and their concentration in sunscreens can affect efficacy, aesthetics and potential toxicity from free radical production. The simulation results reveal that, unless very small nanoparticles can be shown to be safe, there is no combination of particle size and concentration that will deliver optimal performance in terms of sun protection and aesthetics. Such a theoretical method complements well the experimental approach for identifying these characteristics.

    The bee venom melittin shows an antiviral efficacy against the human immunodeficiency virus in cell culture. It was shown to be non-toxic for cats. Aim of this pilot study was to investigate the clinical efficacy and side-effects of melittin in cats naturally infected with feline immunodeficiency virus (FIV). The study was performed as a prospective, placebo-controlled double-blinded trial. Twenty cats were included, of which 10 cats each were treated with either melittin (500 µg/kg body weight) or phosphate-buffered saline (placebo) subcutaneously twice per week. During the treatment period of 6 weeks, the cats' general health status, determined by the Karnofsky's score, and the severity of clinical signs (conjunctivitis and stomatitis) using a clinical scoring system were evaluated. Haematology, biochemistry profiles, lymphocyte subpopulations, CD4/CD8 ratio, and pterines (biopterine, 7-xanthopterine) as surrogate parameters were also compared. The general health status and the clinical scores for conjunctivitis and stomatitis improved in cats treated with melittin. A statistically significant improvement however could only be detected for conjunctivitis in cats treated with melittin compared to cats treated with placebo which was likely due to different scores between both groups at the beginning. No influence on the lymphocyte subpopulations, CD4/CD8 ratio, and pterine concentrations was observed. No side effects occurred in this study. In the protocol used in the present study, no significant efficacy of melittin could be detected. However, efficacy of melittin, especially if applied in a higher dosage as in the present study or for a longer period, could be evaluated in further studies. Synergistic effects if used in combination with classic antiretroviral drugs could be an interesting future approach.

    1978-01-01

    This study is designed to determine the efficacy of nuclear medicine procedures in clinical practice. Several methods of determining efficacy will be evaluated to determine those most suitable. Nuclear medicine methods will be confined to the study of lung diseases by pulmonary perfusion and ventilation. In addition to evaluating the above methods data will be obtained to determine the sensitivity, specificity, predictive value and efficiency of the test under consideration. These values, corrected for prevalence of the disease processes under consideration will then be compared to the values obtained by the MACRO and MICRO methods and will help to bound the clinical reliability of the diagnostic method depending on the degree to which the several methods trend together. Depending on the practicality of these two methods, in addition to the determination of efficacy, cost effectiveness factors and benefit-risk estimates which are used to apply to radiation effects will be determined for nuclear medicine studies of the brain, bone, heart, liver and thyroid subsequently. The measurement techniques will then be utilized to establish guidelines for the most useful applications of the given procedure so that clinicians will be able to obtain a pretest estimate of the utility of the nuclear medicine test.

    Full Text Available Objective: To explore the clinical efficacy of valsartan combined with hydrochlorothiazide in the treatment of elderly hypertension. Methods: A total of 150 elderly patients with primary hypertension who were admitted in our hospital from January, 2015 to January, 2016 were included in the study and randomized into the observation group and the control group. The patients in the control group were given valsartan, 80 mg/time, 1 time/d. On this basis, the patients in the observation group were given additional hydrochlorothiazide 12.5 mg/time, 1 time/d. The patients in the two groups were administered with drugs in the morning. Six-month treatment was regarded as one course. The change of 24 h ambulatory blood pressure before and after treatment was detected, and the efficacy was evaluated. The heart color ultrasound was used to detect LVM and LVMI before and after treatment in the two groups. Results: The total effective rate in the observation group (90.7% was significantly superior to that in the control group (70.7% (P<0.05. The mean SBP and DBP 24h after treatment in the two groups were significantly reduced when compared with before treatment (P<0.05, and those in the observation group were significantly superior to those in the control group (P<0.05. LVM and LVMI after treatment in the two groups were significantly reduced when compared with before treatment (P<0.05, and those in the observation group were significantly superior to those in the control group (P<0.05. Conclusions: The combination of valsartan and hydrochlorothiazide in the treatment of elderly hypertension can effectively enhance the clinical efficacy, and effectively control the blood pressure. It is superior to that by a single drug; therefore, and deserves to be widely recommended in the clinic.

  18. Safety and clinical efficacy of some radiation-sterilized medical products and pharmaceuticals

    International Nuclear Information System (INIS)

    Kulkarni, R.D.; Gopal, N.G.S.

    1975-01-01

    Medical products and pharmaceuticals must conform to certain minimum physico-chemical microbiological and biological requirements. The biological requirements comprise principally testing for toxicity, safety, and pyrogens. Besides the above-mentioned criteria, there are two other important characteristics, viz. clinical efficacy and tolerance in animal and/or human beings. These latter requirements, expected from the final product released for general human use, are not carried out routinely. In the present-day pharmaceutical and medical technology, numerous mew products are appearing, many of them requiring radiation sterilization as they are not stable towards the other conventional methods of sterilization. While the post-irradiation physicochemical changes in a product may not be significant, the bio-availability or biological activity of the product may be affected to a more significant extent. Some evidence of this has recently been reported. Hence, it is desirable to carry out studies on safety as well as clinical efficacy on irradiated products. This paper describes some studies on plastic-based medical products, a pharmaceutical raw material, a typical infusion fluid such as normal saline, antibiotics and their ointments. (author)

  19. Closing the antidepressant efficacy gap between clinical trials and real patient populations.

    Science.gov (United States)

    Wade, Alan G

    2006-01-01

    Overall, patient outcomes in the primary care of depression are seldom as good as those achieved in clinical trials - the "efficacy gap". Many factors contribute to this, including poor patient compliance, poor family and social support and negative media reporting of antidepressants. Indeed, negative media reporting has had far more impact on physicians' prescribing of antidepressants than have regulatory agencies, partly as a result of changing public attitudes. Negative media reports linking SSRIs to increased child suicide rates have also resulted in a decline in the prescribing of SSRIs to this age group, but with no concomitant increase in the prescribing of fluoxetine, the only antidepressant recommended for the treatment of children. There are also inadequacies in the guidelines available to primary care givers that might contribute to the efficacy gap. Guidelines can be too specific for clinical practice - especially where depression coexists with anxiety disorders - and too passive, resulting in delayed or inadequate intervention. Evidence suggests that many physicians prefer to be more proactive. In the recent AHEAD survey, physicians identified faster resolution of symptoms as the property most desirable for improving antidepressant therapy. There is recent evidence that structured long-term therapy and easily-implemented measurement-based care procedures can improve remission rates and help bridge the efficacy gap. If these can be allied with greater public/media understanding of depression and its treatment, along with improved guidelines, then significant progress can be anticipated in the management of mood disorders.

    To evaluate efficacy of a problem-based learning (PBL) pedagogy in preclinical and clinical teaching, test scores of 234 undergraduate dental students from the conventionally taught classes of 2003 and 2004 were compared with scores of 274 dental students from the PBL classes of 2005 and 2006. Although the groups' means were close together, t-test analysis of scores revealed that PBL students performed significantly better than traditional (TRAD) students on midterm (p=.0001) and final (p=.015) examinations taken on student partner/mock patients. ANOVA comparing the classes with each other showed significant differences for the midterm and final, but not for the clinical examination. Further multiple comparison tests (Tukey HSD) for the midterm and final revealed that differences specifically reflected superior performance of PBL classes against one of the TRAD classes (2004). There was no difference in performance between PBL (n=134) and TRAD (n=233) students on examinations taken with actual clinical patients who were undergoing nonsurgical periodontal treatment. Over a two-year period, PBL students rated their program instructors at a mean of 4.41 on a Likert-type scale of 1 (not helpful) to 5 (outstanding). The program provides a PBL model for teaching preclinical and clinical skills supported by a four-year evaluation of manual skills outcomes.

    This paper reports a study to determine how supervisees' backgrounds and surrounding infrastructure predict the efficacy of clinical supervision among Finnish nursing staff, their job satisfaction, levels of burnout and perceptions of the quality of care. Several studies have described the effects of clinical supervision, but few have focused on evaluating it. Until recently, no studies have examined how clinical supervision evaluations are related to supervisees' backgrounds, surrounding infrastructure or respondents' levels of burnout, job satisfaction and perceptions of the quality of care. The survey involved supervisees completing a range of standardized and validated evaluation measures. The respondents were identified from 12 regional, central and university hospitals across Finland (n = 799). The data collection took place from October 2000 to February 2001. The evaluations varied statistically significantly and were associated with statistically significant variations in the respondents' backgrounds. Clinical supervision infrastructure was also strongly related to evaluation scores. Supervisees' age, education, gender, employment status, area of specialty, working hours, work experience and experience as a supervisor were statistically significant predictors for evaluations of the efficacy of clinical supervision. These evaluations of clinical supervision were also found to predict the respondents' job satisfaction, levels of burnout and assessments of good nursing. Nursing staff, especially those who have over 10 years' work experience, work in general care, have a nursing diploma, are non-tenured, work part-time and work 24-hour rotating shifts can benefit from clinical supervision. However, resources need to be invested in supervisor education and nursing staff need to be encouraged to start working in both supervisor and supervisee roles because of the positive effects on job satisfaction and quality of care.

    to investigate the relationship between religiosity, coping styles, self-efficacy and personality dimensions as predictors of satisfaction with clinical experience in rehabilitation interns during transition from academic study to clinical internship. a cross-sectional survey design. five rehabilitation faculties. three hundred and eighteen undergraduate rehabilitation interns, including physical therapy, occupational therapy and speech and language pathology students. Islamic Religiosity Scale, Ways of Coping Questionnaire, General Self-efficacy Scale, NEO Five Factor Inventory, and Satisfaction with Clinical Experiences Questionnaire. religiosity, problem-focused coping and general self-efficacy had significant positive correlation with satisfaction with clinical internship in rehabilitation students. Among personality dimensions, openness, agreement and consciousness had significant positive correlation with satisfaction with clinical experience and neuroticism had significant negative correlation with satisfaction with clinical experience. The results of regression analysis demonstrated that religiosity and self-efficacy had important roles in the prediction of satisfaction with clinical experience in all the rehabilitation intern students of three disciplines (physical therapy, occupational therapy, and speech and language pathology). religiosity, problem-focused coping and general self-efficacy seem to be good predictors of satisfaction with clinical internship in rehabilitation students.

    The aim of this study was to evaluate the short-term adverse events and therapeutic efficacy of transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) with a miriplatin-lipiodol suspension in comparison with a cisplatin-lipiodol suspension. Of patients who underwent TACE for unresectable HCCs in 2009 and 2010, twenty-nine and twenty-seven patients underwent TACE using cisplatin-lipiodol suspension (C-LS) and miriplatin-lipiodol suspension (M-LS), respectively. Adverse events of fever, pain, nausea, anorexia, elevation of aspartate aminotransferase (AST), total bilirubin, creatinine and a decrease in platelet count were evaluated by the National Cancer Institute Common Toxicity Criteria Ver.4. to compare the C-LS and M-LS groups. The short-term therapeutic efficacy of both groups was evaluated by the treatment effect (TE) on the CT images three months after TACE according to the General Rules for the Clinical and Pathological Study of Primary Liver Cancer (the 5th edition, Revised Version). With regard to the adverse events, the M-LS group had significantly less fever and anorexia than the C-LS group. No critical adverse events were observed in either group. The therapeutic efficacy was not significantly different between the groups. TACE with M-LS had fewer adverse events than TACE with C-LS, but neither TACE led to any critical adverse events. The short-term therapeutic efficacy of TACE with M-LS was equivalent to that of TACE with C-LS. (author)

    Meta-analyses in clinical research usually aimed to evaluate treatment efficacy and safety in direct comparison with a unique comparator. Indirect comparisons, using the Bucher's method, can summarize primary data when information from direct comparisons is limited or nonexistent. Mixed comparisons allow combining estimates from direct and indirect comparisons, increasing statistical power. There is a need for simple applications for meta-analysis of indirect and mixed comparisons. These can easily be conducted using a Microsoft Office Excel spreadsheet. We developed a spreadsheet for indirect and mixed effects comparisons of friendly use for clinical researchers interested in systematic reviews, but non-familiarized with the use of more advanced statistical packages. The use of the proposed Excel spreadsheet for indirect and mixed comparisons can be of great use in clinical epidemiology to extend the knowledge provided by traditional meta-analysis when evidence from direct comparisons is limited or nonexistent.

    We evaluated the efficacy and safety of tofacitinib in patients with rheumatoid arthritis (RA) in a real-world setting. Seventy consecutive patients, for whom tofacitinib was initiated between November 2013 and May 2016, were enrolled. All patients fulfilled the 2010 ACR/EULAR classification criteria for RA. All patients received 5 mg of tofacitinib twice daily and were followed for 24 weeks. Clinical disease activity indicated by disease activity score (DAS)28-ESR, the simplified disease activity index, and the clinical disease activity index as well as adverse events (AEs) were evaluated. Statistical analysis was performed to determine which baseline variables influenced the efficacy of tofacitinib at 24 weeks. Fifty-eight patients (82.9%) continued tofacitinib at 24 weeks. Clinical disease activity rapidly and significantly decreased, and this efficacy continued throughout the 24 weeks: i.e., DAS28-ESR decreased from 5.04 ± 1.33 at baseline to 3.83 ± 1.11 at 4 weeks and 3.53 ± 1.17 at 24 weeks (Ptofacitinib treatment. The efficacy of tofacitinib was not changed in patients without concomitant use of methotrexate (MTX) or patients whose treatment with tocilizumab (TCZ) failed. Multivariable logistic analysis showed that the number of biologic DMARDs (bDMARDs) previously used was independently associated with achievement of DAS-low disease activity. Our present study suggests that tofacitinib is effective in real-world settings even without concomitant MTX use or after switching from TCZ. Our results also suggest that its efficacy diminishes if started after use of multiple bDMARDs.

  8. Student distress in clinical workplace learning: differences in social comparison behaviours.

    In medical education, student distress is known to hamper learning and professional development. To address this problem, recent studies aimed at helping students cope with stressful situations. Undergraduate students in clinical practice frequently use experiences of surrounding peers to estimate their abilities to master such challenging situations. This use of the experiences of others, known as social comparison, may affect student distress both positively and negatively. To find characteristics of a beneficial use of social comparison, we examined differences in comparison behaviours between students expressing low and high levels of distress. The participants in our study, response rate 93% (N = 301/321), were all medical students in their first year in clinical practice. They completed the General Health Questionnaire (GHQ-12) to measure distress, and three separate questionnaires to measure: (1) orientation to comparison, (2) motive for comparison, and (3) interpretation of comparison. Differences were analysed using multivariate analysis of variance. Although all students were oriented towards social comparison, the analyses showed that this orientation was less apparent among low-distress students. Besides, the low-distress students were less inclined to use motives indicative for comparisons with peers perceived as performing worse and were less negative in the interpretations of their comparisons. As social comparison is frequently used among all students, we recommend to make them aware of their comparison behaviours and inform them about the pros and cons of the distinguished aspects of the comparison process.

    To evaluate the clinical efficacy of sublingual immunotherapy (SLIT) with house-dust mite (HDM) extract and to examine the change of biomarkers (TIM-1, IL-5 and IL-10) after 6-month SLIT in children with allergic rhinitis (AR). One hundred and sixteen HDM-sensitized children with persistent AR were enrolled to assess the clinical efficacy of SLIT by determining the individual nasal symptom score (INSS) and total nasal symptom scores (TNSS) after 6-month SLIT. Moreover, the mRNA expression of TIM-1, IL-5 and IL-10 in peripheral blood mononuclear cells (PBMCs) was examined in 16 well-controlled and 12 uncontrolled AR patients using quantitative reverse transcription polymerase chain reaction (qRT-PCR). After 6-month SLIT, both TNSS and INSS scores were significantly decreased compared with the baseline value (p < 0.01). The rates for well-controlled, partly controlled and uncontrolled children were 43.1%, 32.8% and 24.1%, respectively. Accordingly, the mRNA levels of TIM-1 and IL-5 decreased significantly and IL-10 mRNA level increased significantly compared with the baseline value in well-controlled children (p < 0.05). Our findings suggest SLIT with HDM extract is effective and safe for AR children and TIM-1 may be considered as an indicator for evaluating the clinical efficacy of SLIT.

    Although the mechanism by which Bacillus Calmette-Guerin (BCG) exerts an antitumor effect on superficial bladder tumors is not fully understood, recent evidence has implicated binding of BCG organisms to fibronectin (FN) as requisite for this antitumor efficacy. Various substrains of BCG and other mycobacteria were tested in vitro for their relative capacities to bind both matrix and soluble FN. A substrain of Mycobacterium kansasii, designated the "high-binding strain," was found to bind FN more readily (P less than 0.05) in in vitro studies, when compared to commercially available substrains of BCG (Tice, Connaught, and Armand Frappier). The binding by the three commercial strains of BCG to FN in vitro appeared to be equivalent. The high-binding strain was further demonstrated to attach more readily in vivo to the acutely injured murine bladder (P less than 0.005) than the Armand Frappier substrain. Finally, using the MB49 murine bladder tumor model, an enhanced antitumor effect (P less than 0.05) was noted in mice treated with intravesical high-binding strain, in comparison to the Armand Frappier substrain, during five weekly treatments. It appears not only that the commercial substrains of BCG bind FN in an equivalent manner but also that the relative binding capacities of the substrains correlate directly with antitumor activity. A substrain of M. kansasii appears to have been identified which may prove more clinically effective than the currently available strains of BCG.

    Attention-deficit hyperactivity disorder (ADHD) is a common psychiatric disease with a worldwide pooled prevalence of 5.29%. To compare the efficacy of Risperidone with Haloperidol in the treatment of attention-deficit hyperactivity disorder (ADHD) among 3- to 6-year-old children. In a 6-week double-blind clinical trial, the efficacy of Risperidone 0.5-2 mg with a dose of maximum Haloperidol 0.075 mg/kg was assessed in 39 children aged 3-6 years. This study was conducted at the Golestan Psychiatric Clinic (Ahvaz, Iran). Measurement tools included the Conners' Parent Rating Scale (CPRS-48), Children's Global Assessment Scale (CGAS), and the Attention Deficit Hyperactivity Disorder Rating Scale (ADHD-RS). Data were analyzed using the Wilcoxon, Mann-Whitney, and Fisher's exact tests in the SPSS 19. During the 6 weeks, the decline in points was seen in Conner's rating scale and in ADHD-RS score in Risperidone and Haloperidol groups (pscale, an increase of performance in both groups for six weeks was statistically significant (pscales of ADHD-RS and CPRS-48, no statistically significant difference was observed between the two treatment groups; i.e., in terms of reducing the rate during weeks of two, four, and six (p>0.05). Haloperidol and Risperidone possibly can be an acceptable treatment choice in the ADHD treatment of 3- to 6-year-old children. The trial was registered at the Iranian Registry of Clinical Trials (http://www.irct.ir) with the Irct ID: IRCT2015082623766N1.

    An efficacy clinical trial with pentavalent rotavirus vaccine (PRV), RotaTeq(®), was conducted at Matlab field site of ICDDR,B, Bangladesh from March 2007 to March 2009. The methodology, including operation logistics, and lessons-learned are described in this report. Vaccination was organized at 41 fixed-site clinics twice/month. A total of 1136 infants were randomized 1:1 to receive 3 doses of PRV/placebo at approximately 6-, 10-, and 14-weeks of age with routine vaccines of the Expanded Programme on Immunization (EPI) schedule. Twelve field-workers routinely visited study participants for safety and efficacy follow-up. The study was conducted following good clinical practices and maintaining cold-chain requirements. There were no temperature deviations of clinical vaccine supplies. Data entry was done using the source documents to a central database developed by the sponsor which was linked to web. Among enrolled infants, 1128 (99.3%) received 3 doses of PRV/placebo and efficacy follow-up was conducted for a median of 554 days. For the evaluation of immunogenicity, blood samples were collected from 150 participants predose 1 and from 147 (98%) of the same participants post dose 3. Stool samples were collected from 778 (99.9%) acute gastroenteritis episodes among children who reported to diarrhoea treatment centres. Thirty-nine serious adverse events, including 6 deaths, occurred among study participants. The efficacy of PRV against severe rotavirus gastroenteritis was 42.7% through the entire follow-up period; serum anti-rotavirus IgA response was 78.1%. Inclement weather, difficult transportation, and movement of study participants were some of the challenges identified. This is the first vaccine trial in rural Bangladesh with online data entry. The study was well accepted in the community and was completed successfully. Copyright © 2011 Elsevier Ltd. All rights reserved.

    The aim of this study was to compare the efficacy of preoperative and postoperative dexketoprofen trometamol for pain control after third molar surgery. Sixty subjects indicated for impacted mandibular third molar surgery were randomly assigned to two groups: preoperative (group 1, n = 30) and postoperative (group 2, n = 30) administration. Group 1 received 25 mg of dexketoprofen trometamol 30 min before surgery and 1 placebo capsule (same color and size with active drug) immediately after surgery. Group 2 received the placebo capsule 30 min before surgery and 25 mg of dexketoprofen trometamol immediately after surgery. Pain intensity was assessed using a numeric rating scale (NRS) during the first 8 h. The time of the need for a second dose of dexketoprofen trometamol, after the first administration, was recorded. The data were analyzed using mixed-model repeated-measures (MMRM), Wilcoxon rank-sum, and Kaplan-Meier analysis. After the 8 h period, no statistically significant difference was observed in the intensity of pain (MMRM, p = 0.41); and no significant difference in the time for a second dose (p = 0.956). In conclusion, preoperative administration of dexketoprofen trometamol is a reasonable clinical approach that is as effective as conventional postoperative pharmacological treatment, with the advantage of allowing early analgesia before pain develops.

    Full Text Available Objective. The objective of this review is to investigate the detailed existing scientific information about the clinical efficacy of acupuncture on rheumatoid arthritis (RA conditions and to reveal the proposed mechanisms. Methods. We searched the PubMed, EMBASE, Cochrane, AMED (Allied and Complementary Medicine, NCCAM (The National Center for Complementary and Alternative Medicine, and CNKI (China National Knowledge Infrastructure databases to identify relevant monographs and related references from 1974 to 2018. Chinese journals and theses/dissertations were hand searched. Results. 43 studies were recruited. Each research was analyzed for study design, subject characteristics, intervention, selected acupoints, assessment parameters, proposed mechanisms, and results/conclusions. Conclusions. In our review, we concluded that acupuncture alone or combined with other treatment modalities is beneficial to the clinical conditions of RA without adverse effects reported and can improve function and quality of life and is worth trying. Several important possible mechanisms were summarized including anti-inflammatory effect, antioxidative effect, and regulation of immune system function. However, there is still inconsistency regarding the clinical efficacy and lack of well-designed human/animal double-blinded RCTs. Future discussion for further agreement on taking traditional Chinese medicine (TCM theory into consideration as much as possible is a top priority.

    The purpose of this trial is to evaluate the clinical efficacy and cost/effectiveness of Saccharomyces boulardii compared with yogurt fluid (YF) in acute non-bloody diarrhea in children. This randomized, prospective open-label clinical trial includes 55 children (36 boys, 19 girls; mean age 21.2 ± 28.2 months). Group A (N = 28) received lyophilized S. boulardii and group B (N = 27) received YF. The duration of diarrhea was shorter with S. boulardii but the hospital stay was reduced with YF, although these differences were not significant. However, diarrhea had resolved in significantly more children on day 3 in the S. boulardii group (48.5% versus 25.5%; P < 0.05). In outpatient cases, yogurt treatment was cheaper than S. boulardii whereas in hospitalized patients, treatment cost was similar. In conclusion, the effect of daily freshly prepared YF was comparable to S. boulardii in the treatment of acute non-bloody diarrhea in children. The duration of diarrhea was shorter in the S. boulardii group, expressed as a significantly higher number of patients with normal stools on day 3. PMID:20207879

    Full Text Available Feng He, Li-bo Man, Gui-zhong Li, Ning Liu Department of Urinary Surgery, Beijing Jishuitan Hospital, Beijing, People’s Republic of China Objective: To critically evaluate the efficacy of an α-blocker in improving ureteral-stent-related symptoms and preliminarily investigate the difference between different types of α-blockers. Methods: Relevant randomized controlled trials were identified through searching PubMed, the Cochrane Library, Embase, and other sources. After quality assessment and data abstraction, direct comparison based on the Ureteral Stent-related Symptom Questionnaire (USSQ between α-blockers and control was performed by RevMan 5.3. Indirect comparison between different types of α-blockers was performed by ITC 1.0. Sensitive and subgroup analyses were used to handle important clinical factors. Results: Sixteen randomized controlled trials containing 1,489 cases were included. Compared with control, α-blockers significantly reduced the overall urinary symptom, pain index, general health index, and scores related to sexual matters, while no significant difference was found in work performance and additional problem scores. Subgroup analysis showed that the duration of stent insertion, patient’s age, stent size, and the type of α-blocker had the potential to influence the outcomes. Through indirect comparison, we found alfuzosin and terazosin to be better than tamsulosin in pain relief and general health improvement. Conclusion: α-Blocker was effective in treating ureteral stent-related symptoms, as it improved the major indexes of USSQ post-insertion or post-removal. Alfuzosin and terazosin seemed to be better than tamsulosin, which needs further verification because of the lack of direct comparison currently.

    Objective For people living with HIV, treatment adherence self-efficacy is an important predictor of treatment adherence and therefore of clinical outcomes. Using experience sampling method (ESM), this study aimed to examine: (1) the within-person association between moment-to-moment changes in social support and HIV treatment self-efficacy; (2) the moderators of this within-person association, (3) the concordance between questionnaire and ESM measurement of treatment self-efficacy; and (4) the utility of each approach (ESM and questionnaire) in predicting adherence to medication, adherence to clinic visits, CD4 counts, and viral load. Methods 109 men living with HIV responded to the same set of ESM questions 3 times a day for 7 days via a smart phone given to them for the study. They also completed cross-sectional questionnaires and their clinic data was extracted from medical records in order to examine predictors and consequences of state and trait treatment self-efficacy. Results In within-person hierarchical linear modeling (HLM) analyses, receipt of recent social support predicted higher current ESM treatment self-efficacy. This association was stronger for individuals reporting higher avoidance coping with HIV. The correlation between ESM and questionnaire measures of treatment self-efficacy was r = .37. ESM measure of average treatment self-efficacy predicted medication adherence, visit adherence, CD4 counts, and viral load, while questionnaire-based self-efficacy did not predict these outcomes. Conclusion Interventions aimed at improving treatment adherence may target social support processes, which may improve treatment self-efficacy and adherence. PMID:27089459

    Disinfection of dental impressions is an indispensable procedure for the control of cross-contamination; however, there is limited information on the efficacy of disinfection under clinical conditions. The objective of this study was to clinically evaluate the disinfection efficacy of commercially available agents in removing oral pathogens from patient-derived impressions. Impressions from 54 patients were divided into groups and either left undisinfected or underwent 1 of 5 disinfection treatments: (1) 2% glutaraldehyde (GA), (2) 1% sodium hypochlorite (SH), (3) 0.25% benzalkonium chloride (BC), (4) 1 ppm ozonated water (OW), or (5) the Hygojet/MD520 system (HJ). An impression culture technique using a brain heart infusion agar medium was used to visualize the microbial contamination on the surface of the impression cultures. The persistent presence of oral pathogens on the impression cultures was examined using selective isolation agar plates. The isolation frequencies of streptococci, staphylococci, Candida, methicillin-resistant Staphylococcus aureus, and Pseudomonas aeruginosa species from undisinfected impressions were 100%, 55.6%, 25.9%, 25.9% and 5.6%, respectively. Disinfection with HJ and BC removed the microorganisms with the greatest efficacy, followed by GA, SH, and OW. Potential bacterial contamination could be detected even after disinfection had been performed. Combined use of BC plus GA or SH removed oral pathogens almost completely from dental impressions. This investigation showed that potential contaminants are still present, even after general disinfection procedures. Therefore, either HJ or the combined use of BC with GA or SH is recommended for clinical and laboratory use.

    Ponesimod is currently the only S1P receptor modulator studied in psoriasis. In a dose-finding study, the active doses showed similar efficacy. Prediction of efficacy at lower doses to aid clinical phase 3 planning with respect to dose selection, duration of treatment, and patient inclusion criteria based on pharma-co-kinetic/pharmacodynamic (PK/PD) modeling and simulation. The dose-finding study treated 326 patients (67 on placebo, 126 on 20mg, and 133 on 40mg) over 16 weeks. PK/PD modeling of steady-state trough concentrations and longitudinal PASI scores was employed to characterize data and simulate scenarios. PASI score continually decreased with time on ponesimod treatment, reaching a plateau at 16 weeks. Absolute and relative (percent) PASI score change was larger in patients with higher PASI score at baseline. Doses below 10mg were predicted to show lower efficacy than doses of 10mg and higher. Concentration-response modeling was able to predict the efficacy of doses that were not studied. In psoriasis patients, a dose of 10mg (not administered in the study) was predicted to show efficacy similar to 20mg. Disease status (PASI score at baseline) as study inclusion criterion has pronounced influence on study outcome. Copyright © 2017 Japanese Society for Investigative Dermatology.

Fluoxetine, a selective inhibitor of serotonin reuptake (SSRI, is widely utilized in the management of GAD in clinical practice despite the lack of strong evidence. This article reviews fluoxetine trials to investigate fluoxetine's efficacy and tolerability in Chinese patients with GAD. Methods: A literature review was conducted using the following databases up to and including April 2013: Chinese BioMedical Literature, China National Knowledge Infrastructure, EMBASE, MEDLINE, and PsycINFO. We selected clinical studies that utilized fluoxetine for GAD in which all participants were Chinese. Results: Fifteen open-label, non-placebo trials were identified and analyzed; eleven anxiolytics were compared with fluoxetine separately. Short-term efficacy of fluoxetine had been established in these open-label, head-to-head controlled trials. Fluoxetine had rapid onset of action (approximately 1–2 weeks and seemed to be effective in maintenance treatment. Fluoxetine was generally well-tolerated with the most common side effect of dry month and nausea. Compared to other anxiolytic agents, fluoxetine was equivalent with all of the comparative anxiolytics in terms of efficacy except mirtazapine which showed conflicting results with fluoxetine in two studies. In terms of side effects, fluoxetine was better tolerated than diazepam, doxepine, and amitriptyline, less tolerated than escitalopram, and had similar tolerability with duloxetine as well as alprazolam. Conclusion: Given the high risk of bias of the included studies, the overall small sample

    In 2010, the World Health Organization published benchmarks for training in osteopathy in which osteopathic visceral techniques are included. The purpose of this study was to identify and critically appraise the scientific literature concerning the reliability of diagnosis and the clinical efficacy of techniques used in visceral osteopathy. Databases MEDLINE, OSTMED.DR, the Cochrane Library, Osteopathic Research Web, Google Scholar, Journal of American Osteopathic Association (JAOA) website, International Journal of Osteopathic Medicine (IJOM) website, and the catalog of Académie d'ostéopathie de France website were searched through December 2017. Only inter-rater reliability studies including at least two raters or the intra-rater reliability studies including at least two assessments by the same rater were included. For efficacy studies, only randomized-controlled-trials (RCT) or crossover studies on unhealthy subjects (any condition, duration and outcome) were included. Risk of bias was determined using a modified version of the quality appraisal tool for studies of diagnostic reliability (QAREL) in reliability studies. For the efficacy studies, the Cochrane risk of bias tool was used to assess their methodological design. Two authors performed data extraction and analysis. Eight reliability studies and six efficacy studies were included. The analysis of reliability studies shows that the diagnostic techniques used in visceral osteopathy are unreliable. Regarding efficacy studies, the least biased study shows no significant difference for the main outcome. The main risks of bias found in the included studies were due to the absence of blinding of the examiners, an unsuitable statistical method or an absence of primary study outcome. The results of the systematic review lead us to conclude that well-conducted and sound evidence on the reliability and the efficacy of techniques in visceral osteopathy is absent. The review is registered PROSPERO 12th of December

    Full Text Available We evaluated the efficacy and safety of tofacitinib in patients with rheumatoid arthritis (RA in a real-world setting.Seventy consecutive patients, for whom tofacitinib was initiated between November 2013 and May 2016, were enrolled. All patients fulfilled the 2010 ACR/EULAR classification criteria for RA. All patients received 5 mg of tofacitinib twice daily and were followed for 24 weeks. Clinical disease activity indicated by disease activity score (DAS28-ESR, the simplified disease activity index, and the clinical disease activity index as well as adverse events (AEs were evaluated. Statistical analysis was performed to determine which baseline variables influenced the efficacy of tofacitinib at 24 weeks.Fifty-eight patients (82.9% continued tofacitinib at 24 weeks. Clinical disease activity rapidly and significantly decreased, and this efficacy continued throughout the 24 weeks: i.e., DAS28-ESR decreased from 5.04 ± 1.33 at baseline to 3.83 ± 1.11 at 4 weeks and 3.53 ± 1.17 at 24 weeks (P<0.0001, vs. baseline. 15 AEs including 5 herpes zoster infection occurred during tofacitinib treatment. The efficacy of tofacitinib was not changed in patients without concomitant use of methotrexate (MTX or patients whose treatment with tocilizumab (TCZ failed. Multivariable logistic analysis showed that the number of biologic DMARDs (bDMARDs previously used was independently associated with achievement of DAS-low disease activity.Our present study suggests that tofacitinib is effective in real-world settings even without concomitant MTX use or after switching from TCZ. Our results also suggest that its efficacy diminishes if started after use of multiple bDMARDs.

    Measurements of natural global and diffuse illuminance on four vertical surfaces exposed to north, east, south and west have been carried out at Arcavacata di Rende (Italy). In the work the mean hourly values of the global and diffuse luminous efficacy measured in the period of a year are presented. The hourly data have been compared with the predictions of many calculation models. The comparisons show that, for global efficacy, the differences among the various models are not significant, and the use of a model with a constant value of efficacy gives good predictions of global illuminance. For the prediction of diffuse illuminance the different models behave in a similar way if their coefficients are recalculated and, again, the use of a constant diffuse efficacy provides a good estimate of diffuse illuminance on vertical surfaces

    2009-01-01

    Full Text Available This review will focus on recent advances in the application of antiepidermal growth factor receptor (anti-EGFR for the treatment of breast cancer. The choice of EGFR, a member of the ErbB tyrosine kinase receptor family, stems from evidence pinpointing its role in various anti-EGFR therapies. Therefore, an increase in our understanding of EGFR mechanism and signaling might reveal novel targets amenable to intervention in the clinic. This knowledge base might also improve existing medical treatment options and identify research gaps in the design of new therapeutic agents. While the approved use of drugs like the dual kinase inhibitor Lapatinib represents significant advances in the clinical management of breast cancer, confirmatory studies must be considered to foster the use of anti-EGFR therapies including safety, pharmacokinetics, and clinical efficacy.

    The low efficacy of rotavirus vaccines in clinical trials performed in low-resource settings may be partially explained by acquired immunity from natural exposure, especially in settings with high disease incidence. In a clinical trial of monovalent rotavirus vaccine in Bangladesh, we compared the original per-protocol efficacy estimate to efficacy derived from a recurrent events survival model in which children were considered naturally exposed and potentially immune after their first rotavirus diarrhea (RVD) episode. We then simulated trial cohorts to estimate the expected impact of prior exposure on efficacy estimates for varying rotavirus incidence rates and vaccine efficacies. Accounting for natural immunity increased the per-protocol vaccine efficacy estimate against severe RVD from 63.1% (95% confidence interval [CI], 33.0%-79.7%) to 70.2% (95% CI, 44.5%-84.0%) in the postvaccination period, and original year 2 efficacy was underestimated by 14%. The simulations demonstrated that this expected impact increases linearly with RVD incidence, will be greatest for vaccine efficacies near 50%, and can reach 20% in settings with high incidence and low efficacy. High rotavirus incidence leads to predictably lower vaccine efficacy estimates due to the acquisition of natural immunity in unvaccinated children, and this phenomenon should be considered when comparing efficacy estimates across settings.

    Illness severity and self-efficacy are two constructs of growing interest as predictors of clinical response in alcoholism. Using alternative measures of illness severity (DSM-IV symptom count, Alcohol Dependence Scale, and Addiction Severity Index) and self-efficacy (brief version of the Situational Confidence Questionnaire) rigorously controlled for theoretically important background variables, we studied their unique contribution to multiple indices of relapse, relapse latency, and use of alternative coping behaviors in a large, heterogeneous clinical sample. The Alcohol Dependence Scale contributed to the prediction of 4 of 5 relapse indicators. The SCQ failed to predict relapse behavior or its precursor, coping response. The findings emphasize the predictive validity of severity of dependence as a course specifier and underline the need for more sensitive and externally valid measures of cognitive processes such as self-efficacy for application in future studies of posttreatment behavior.

    To evaluate the clinical efficacy and effectiveness of using 3D printing to develop medical devices across all medical fields. Systematic review compliant with Preferred Reporting Items for Systematic Reviews and Meta-Analyses. PubMed, Web of Science, OVID, IEEE Xplore and Google Scholar. A double-blinded review method was used to select all abstracts up to January 2017 that reported on clinical trials of a three-dimensional (3D)-printed medical device. The studies were ranked according to their level of evidence, divided into medical fields based on the International Classification of Diseases chapter divisions and categorised into whether they were used for preoperative planning, aiding surgery or therapy. The Downs and Black Quality Index critical appraisal tool was used to assess the quality of reporting, external validity, risk of bias, risk of confounding and power of each study. Of the 3084 abstracts screened, 350 studies met the inclusion criteria. Oral and maxillofacial surgery contained 58.3% of studies, and 23.7% covered the musculoskeletal system. Only 21 studies were randomised controlled trials (RCTs), and all fitted within these two fields. The majority of RCTs were 3D-printed anatomical models for preoperative planning and guides for aiding surgery. The main benefits of these devices were decreased surgical operation times and increased surgical accuracy. All medical fields that assessed 3D-printed devices concluded that they were clinically effective. The fields that most rigorously assessed 3D-printed devices were oral and maxillofacial surgery and the musculoskeletal system, both of which concluded that the 3D-printed devices outperformed their conventional comparators. However, the efficacy and effectiveness of 3D-printed devices remain undetermined for the majority of medical fields. 3D-printed devices can play an important role in healthcare, but more rigorous and long-term assessments are needed to determine if 3D-printed devices are

Methylphenidate (MPH, a central nervous system stimulant, is commonly used for pharmacological treatment of adults and children with ADHD. Current practice guidelines recommend optimizing MPH dosage to individual patient needs; however, the clinical benefits of individual dose optimization compared with fixed-dose regimens remain unclear. Here we review the available literature on MPH dose optimization from clinical trials and real-world experience on ADHD management. In addition, we report safety and efficacy data from the largest MPH modified-release long-acting Phase III clinical trial conducted to examine benefits of dose optimization in adults with ADHD. Overall, MPH is an effective ADHD treatment with a good safety profile; data suggest that dose optimization may enhance the safety and efficacy of treatment. Further research is required to establish the extent to which short-term clinical benefits of MPH dose optimization translate into improved long-term outcomes for patients with ADHD.

    Full Text Available In persons with multiple sclerosis (MS a lowered self-efficacy negatively affects physical activities. Against this background we studied the relationship between self-efficacy and cognitive performance in the early stages of MS. Thirty-three patients with Clinically Isolated Syndrome (CIS and early Relapsing Remitting MS (eRRMS were assessed for self-efficacy (MSSES-18, cognition (CDR System, fatigue (MFIS-5, depressive symptoms (BDI, disease impact (MSIS-29, and disability (EDSS. Correlative analyses were performed between self-efficacy and cognitive scores, and stepwise regression analyses identified predictors of cognition and self-efficacy. Good correlations existed between total self-efficacy and Power of Attention (r= 0.65; P< 0.001, Reaction Time Variability (r= 0.57; P< 0.001, and Speed of Memory (r= 0.53; P< 0.01, and between control self-efficacy and Reaction Time Variability (r= 0.55; P< 0.01. Total self-efficacy predicted 40% of Power of Attention, 34% of Reaction Time Variability, and 40% of Speed of Memory variabilities. Disease impact predicted 65% of total self-efficacy and 58% of control self-efficacy variabilities. The findings may suggest that in persons with CIS and eRRMS self-efficacy may positively affect cognitive performance and that prevention of disease activity may preserve self-efficacy.

    To evaluate and compare the efficacy of platelet-rich fibrin (PRF) with enamel matrix derivative (EMD; Emdogain) in the treatment of periodontal intrabony defects in patients with chronic periodontitis, six months after surgery. Forty-four (44) intrabony defects in 30 patients (15 males) were randomly allocated into two treatment groups: EMD (n = 22) and PRF (n = 22). Measurement of the defects was done using clinical and cone beam computed tomography at baseline and 6 months. Clinical and radiographic parameters such as probing depth, clinical attachment level, intrabony defect depth and defect angle, were recorded at baseline and 6 months post-operatively. Within group change was evaluated using the Wilcoxon signed rank test. Intergroup comparisons were made using the Mann-Whitney U test. Postsurgical measurements revealed that there was an equal reduction in probing depth and a greater but statistically non-significant attachment gain for the Emdogain group when compared to the platelet-rich fibrin group. The Emdogain group presented with significantly greater percentage defect resolution (43.07% ± 12.21) than did the platelet-rich fibrin group (32.41% ± 14.61). Post-operatively the changes in defect width and defect angle were significant in both groups, but upon intergroup comparison they were found to be statistically non-significantly different. Both Emdogain and platelet-rich fibrin were effective in the regeneration of intrabony defects. Emdogain was significantly superior in terms of percentage defect resolution.

    Intestinal lymphangiectasia (IL), a type of protein-losing enteropathy (PLE), is a dilatation of lymphatic vessels within the gastrointestinal tract. Dietary fat restriction previously has been proposed as an effective treatment for dogs with PLE, but limited objective clinical data are available on the efficacy of this treatment. To investigate the clinical efficacy of dietary fat restriction in dogs with IL that were unresponsive to prednisolone treatment or showed relapse of clinical signs and hypoalbuminemia when the prednisolone dosage was decreased. Twenty-four dogs with IL. Retrospective study. Body weight, clinical activity score, and hematologic and biochemical variables were compared before and 1 and 2 months after treatment. Furthermore, the data were compared between the group fed only an ultra low-fat (ULF) diet and the group fed ULF and a low-fat (LF) diet. Nineteen of 24 (79%) dogs responded satisfactorily to dietary fat restriction, and the prednisolone dosage could be decreased. Clinical activity score was significantly decreased after dietary treatment compared with before treatment. In addition, albumin (ALB), total protein (TP), and blood urea nitrogen (BUN) concentration were significantly increased after dietary fat restriction. At 2 months posttreatment, the ALB concentrations in the ULF group were significantly higher than that of the ULF + LF group. Dietary fat restriction appears to be an effective treatment in dogs with IL that are unresponsive to prednisolone treatment or that have recurrent clinical signs and hypoalbuminemia when the dosage of prednisolone is decreased. © 2014 The Authors.

  19. MRI assessment program. Consensus statement on clinical efficacy of MRI

    International Nuclear Information System (INIS)

    This consensus statement is largely based on the experience gained at the MRI units at the four hospitals which have operated scanners in the MRI program. It reflects the considered opinion of the radiologists responsible for the MRI services at those hospitals. Account has also been taken of relevant overseas data. This collection of opinion relates particularly to comparison with other imaging modalities. The specific comments will require further consideration as technical developments with MRI become available, additional experience is gained with gadolinium contrast material and additional data are obtained on the influence of MRI on patient management. MRI, at present, is used either to improve diagnostic accuracy when other tests are negative or equivocal, when there is strong clinical suspicion of disease, or to improve surgical or other management planning when the diagnosis known. In some situations (eg syringomyelia, congenital spinal disease, posterior fossa/cerebello-pontine angle tumours) it may entirely replace other tests (eg myelography, air contrast, CT) which are substantially less accurate and/or more invasive. In other situations (eg hemispheric brain tumours, lumbar disc protrusions) when other tests, such as CT, can be as accurate, MRI is not usually or initially indicated because it is currently more expensive and of limited availability. However, balanced against this is the fact that it does not expose the patient to potentially harmful ionising radiation. It is also stressed that MRI images depend on complex, widely variable and, as yet, incompletely understood parameters. There is concern that this may result in false positive diagnoses, especially where MRI is used alone as a screening test, or used as the initial test. For several reasons (availability, cost, medical and diagnostic efficacy), the specific comments on indications for MRI presented are based upon the assumption that MRI is a tertiary and complementary imaging examination

  20. A comprehensive comparison of the efficacy and tolerability of racecadotril with other treatments of acute diarrhea in adults

    Full Text Available Racecadotril is a guideline-recommended treatment to alleviate symptoms of acute diarrhea. A systematic review of randomized studies was performed comparing efficacy and safety of treatment with racecadotril to that with placebo or active treatments in adults. In five double-blind studies, racecadotril and placebo had comparable tolerability but racecadotril was more effective. This was consistent across multiple efficacy parameters including duration of diarrhea, number of diarrheic stools, abdominal pain and meteorism; it was also consistent across countries in Africa, Asia and Europe. In six randomized studies in outpatients comparing racecadotril to loperamide, resolution of symptoms occurred with similar speed and efficacy; however, racecadotril treatment was associated with less rebound constipation and less abdominal discomfort. A seventh comparative study performed in geriatric nursing home residents reported a superior efficacy of racecadotril. In direct comparison with Saccharomyces boulardii treatment, racecadotril exhibited similar tolerability but was more efficacious. One study compared racecadotril to octreotide in patients with acute diarrhea requiring hospitalization, rehydration and antibiotic treatment; in this cohort, octreotide was more efficacious than racecadotril. In conclusion, in adults with acute diarrhea racecadotril is more efficacious than placebo or Saccharomyces boulardii, similarly efficacious as loperamide and, in patients with moderate to severe disease as add-on to antibiotics, less than octreotide. The tolerability of racecadotril is similar to that of placebo or Saccharomyces boulardii and better than that of loperamide, particularly with regard to risk of rebound constipation. Taken together these data demonstrate that racecadotril is a suitable treatment to alleviate symptoms of acute diarrhea in adults.

    This study investigated the non-inferiority of efficacy and tolerance of 2% miconazole nitrate shampoo in comparison with 2% ketoconazole shampoo in the treatment of scalp seborrheic dermatitis. A randomized, double-blind, comparative, parallel group, multicenter study was done. A total of 274 patients (145 miconazole, 129 ketoconazole) were enrolled. Treatment was twice-weekly for 4 weeks. Safety and efficacy assessments were made at baseline and at weeks 2 and 4. Assessments included symptoms of erythema, itching, scaling ['Symptom Scale of Seborrhoeic Dermatitis' (SSSD)], disease severity and global change [Clinical Global Impressions (CGIs) and Patient Global Impressions (PGIs)]. Miconazole shampoo is at least as effective and safe as ketoconazole shampoo in treating scalp seborrheic dermatitis scalp.

    Objective: To assess the clinical efficacy of interventional management for the treatment of renal artery stenosis. Methods: Percutaneous transluminal balloon renal angioplasty and / or percutaneous transluminal renal artery stenting were performed in 47 patients with renal artery stenosis (55 stenosed arteries in total). A follow-up study on the blood pressure and renal function was conducted and the results were statistically analyzed. Results: Fifty-four stenosed renal arteries were successfully reopened, of which only percutaneous transluminal balloon angioplasty was adopted in 17 and percutaneous transluminal renal artery stenting in 37. One patient died during the procedure. A follow-up for a mean period of (2.5 ± 0.6) years was carried out. The blood pressure determined at one (n = 46), 6 (n = 46), 12 (n = 33) and 24 (n = 29) months after the treatment was significantly decreased when compared to that determined before the treatment (P < 0.01). The clinical effective rate was 89.13% (41 / 46), 72.73% (24 / 33) and 62.07% (18 / 29), respectively. After the therapy,the renal function was improved in 5, remained unchanged in 33 and became worse in 3 patients. The comparison of the post-operative renograms (obtained within 2 months) with the pre-operative ones showed that in eight patients there was an increase in renal blood flow with an improvement in renal function impairment, which took a turn from severe degree to mild or moderate degree. Nevertheless, severe impairment in renal blood flow remained in 3 patients. Conclusion: Percutaneous transluminal balloon renal angioplasty and percutaneous transluminal renal artery stenting are safe and effective treatments for the renal artery stenosis, which also has a beneficial effect on the related renal hypertension and renal insufficiency.

    The objective of this study was to compare the clinical outcomes of the cervical interlaminar epidural steroid injection (CIESI) for unilateral radiculopathy by the midline or paramedian approaches and to determine the prognostic factors of CIESI. We retrospectively analyzed 182 patients who underwent CIESI from January 2009 to December 2012. Inclusion criteria were no previous spinal steroid injection, presence of a cross-sectional image, and presence of follow-up records. Exclusion criteria were patients with bilateral cervical radiculopathy and/or dominant cervical axial pain, combined peripheral neuropathy, and previous cervical spine surgery. Short-term clinical outcomes were evaluated at the first follow-up after CIESI. We compared the clinical outcomes between the midline and paramedian approaches. Possible prognostic factors for the outcome, such as age, gender, duration of radiculopathy, and cause of radiculopathy were also analyzed. Cervical interlaminar epidural steroid injections were effective in 124 of 182 patients (68.1%) at the first follow-up. There was no significant difference in the clinical outcomes of CIESI, between midline (69.6%) and paramedian (63.7%) approaches (p = 0.723). Cause of radiculopathy was the only significant factor affecting the efficacy of CIESI. Patients with disc herniation had significantly better results than patients with neural foraminal stenosis (82.9% vs. 56.0%) (p < 0.001). There is no significant difference in treatment efficacy between the midline and paramedian approaches in CIESI, for unilateral radiculopathy. The cause of the radiculopathy is significantly associated with the treatment efficacy; patients with disc herniation experience better pain relief than those with neural foraminal stenosis.

    The way that the social stigma of mental illness is related with the self-stigma, which in turn affects self-esteem and self-efficacy of mental patients was investigated. A sample of 66 patients in the Adult Psychiatric Clinic of the Thessaloniki General Hospital "G. Papanikolaou" was participated in this descriptive association study, with cross-sectional comparisons. The sample comprised of patients who were hospitalized or visited the Clinic as out-patients during the period that the study was undertaken. A tool for measuring the basic demographic, social and clinical characteristics of the participants was designed and used. Additionally, the Self-Stigma of Mental Illness Scale, SSMIS, Rosenberg's Self-Esteem Scale, RSE and the General Self-Efficacy Sherer Scale, GSESH were used for measuring self-stigma, self-esteem and self-efficacy respectively. Results showed that self-esteem and self-efficacy were highly associated with each another. Self-esteem and self-efficacy co varied. Greater self-stigma was associated with lower self-esteem and selfefficacy confirming the power of this relationship which is connected with patients' psychological empowerment and acts as mediator between patients' self-categorization as "mentally ill" and their self-esteem and self-efficacy. Additionally, a mild negative association between self-esteem, self-efficacy and age was found while higher educational level was associated with greater selfefficacy. Greater self-stigma along with lower educational level were the most significant predictors of both self-esteem and self-efficacy of mental patients, as shown by regression analysis. Some of our results, such as the percentage of low self-esteem (30.3%), were different from previous relevant data (9.1-24%), probably due to differences in sample's cultural characteristics and composition, research tools used, and the degree of mentally ill patients' reaction to social stigma perception. Despite its methodological limitations, the

    A network meta-analysis is used to compare the efficacy of ropinirole, rasagiline, rotigotine, entacapone, apomorphine, pramipexole, sumanirole, bromocriptine, piribedil and levodopa, with placebo as a control, for non-motor symptoms in Parkinson's disease (PD). PubMed, Embase and the Cochrane Library were searched from their establishment dates up to January 2017 for randomized controlled trials (RCTs) investigating the efficacy of the above ten drugs on the non-motor symptoms of PD. A network meta-analysis combined the evidence from direct comparisons and indirect comparisons and evaluated the pooled weighted mean difference (WMD) values and surfaces under the cumulative ranking curves (SUCRA). The network meta-analysis included 21 RCTs. The analysis results indicated that, using the United Parkinson's Disease Rating Scale (UPDRS) III, the efficacies of placebo, ropinirole, rasagiline, rotigotine, entacapone, pramipexole, sumanirole and levodopa in treating PD were lower than that of apomorphine (WMD = -10.90, 95% CI = -16.12∼-5.48; WMD = -11.85, 95% CI = -17.31∼-6.16; WMD = -11.15, 95% CI = -16.64∼-5.04; WMD = -11.70, 95% CI = -16.98∼-5.60; WMD = -11.04, 95% CI = -16.97∼-5.34; WMD = -13.27, 95% CI = -19.22∼-7.40; WMD = -10.25, 95% CI = -15.66∼-4.32; and WMD = -11.60, 95% CI = -17.89∼-5.57, respectively). Treatment with ropinirole, rasagiline, rotigotine, entacapone, pramipexole, sumanirole, bromocriptine, piribedil or levodopa, with placebo as a control, on PD exhibited no significant differences on PD symptoms when the UPDRS II was used for evaluation. Moreover, using the UPDRS III, the SUCRA values indicated that a pomorphine had the best efficacy on the non-motor symptoms of PD (99.0%). Using the UPDRS II, the SUCRA values for ropinirole, rasagiline, rotigotine, entacapone, pramipexole, sumanirole, bromocriptine, piribedil and levodopa treatments, with placebo as a control, indicated that bromocriptine showed the best efficacy on the non

    Full Text Available Background: The systemic use of non-steroidal anti-inflammatory drugs are associated with various side-effects like hepatotoxicity, blood dyscrasias, nephrotoxicity and gastric irritability. Among these, gastric irritability is the most common and the most important one, which should be taken care of. Therefore, it may be preferable to use a local formulation such as a mouthwash to treat the inflammatory conditions of the oral cavity. Aim: To determine the efficacy and acceptability of 0.074% diclofenac mouthwash in relieving pain and inflammation of post-periodontal surgery patients. Materials and Methods: The study was designed as a double-blind, placebo-controlled clinical trial. Twenty chronic periodontitis patients who were scheduled for full-mouth periodontal flap surgery were randomized to receive either diclofenac mouthwash or placebo to rinse with 15 ml of solution daily for a period of 7 days. Modified gingival index (Lobene 1986 was used to verify gingival inflammation and visual analog scale was used to assess pain. After the baseline measurements for all the parameters were recorded, spontaneous pain and burning were evaluated daily while redness and edema were recorded on the 3 rd and 7 th day from the day of treatment. Results: Data obtained were analyzed statistically using paired " t" test for intragroup comparison and unpaired " t"-test for intergroup comparison. Spontaneous pain was significantly reduced by diclofenac mouthwash. Other parameters, i.e. gingival inflammation and swelling, had not shown significant reduction in scores in either group, although the reduction was higher in the test group. Conclusion: The new 0.074% diclofenac mouthwash is an effective and tolerable medicinal product for post-surgical symptomatic relief.

    Objective To assess and compare examiner reliability of clinical and photographic fluorosis examinations using the Fluorosis Risk Index (FRI) among children in the Iowa Fluoride Study (IFS). Methods The IFS examined 538 children for fluorosis and dental caries at age 13 and obtained intra-oral photographs from nearly all of them. To assess examiner reliability, duplicate clinical examinations were conducted for 40 of the subjects. In addition, 200 of the photographs were scored independently for fluorosis by two examiners in a standardized manner. Fluorosis data were compared between examiners for the clinical exams and separately for the photographic exams, and a comparison was made between clinical and photographic exams. For all 3 comparisons, examiner reliability was assessed using kappa statistics at the tooth level. Results Inter-examiner reliability for the duplicate clinical exams on the sample of 40 subjects as measured by kappa was 0.59, while the repeat exams of the 200 photographs yielded a kappa of 0.64. For the comparison of photographic and clinical exams, inter-examiner reliability, as measured by weighted kappa, was 0.46. FRI scores obtained using the photographs were higher on average than those obtained from the clinical exams. Fluorosis prevalence was higher for photographs (33%) than found for clinical exam (18%). Conclusion Results suggest inter-examiner reliability is greater and fluorosis scores higher when using photographic compared to clinical examinations. PMID:22316120

    Tenvermectin (TVM) is a novel 16-membered macrocyclic lactone antibiotics, which contains component TVM A and TVM B. However there is not any report on safety and clinical efficacy of TVM for developing as a potential drug. In order to understand the part of safety and clinical efficacy of TVM, we conducted the acute toxicity test, the standard bacterial reverse mutation (Ames) test and the clinical deworming test. In the acute toxicity studies, TVM, TVM A and ivermectin (IVM) were administrated once by oral gavage to mice and rats. Results showed that the oral LD 50 values of TVM, TVM A and IVM in mice were 74.41, 106.95 and 53.06 mg/kg respectively. The oral LD 50 values of TVM and TVM A in rats were determined to be 164.22 and 749.34 mg/kg respectively. TVM and IVM are moderately toxic substances, meanwhile the TVM A belongs to low toxic compounds, implying that the acute toxicity is highly related to the length of side chain of TVM at position C25. In the Ames test, results showed that TVM did not induce mutagenicity in Salmonella typhimurium TA97a, TA98, TA100, TA102 and TA1535 with and without metabolic activation system, speculating that the mutagenicity is probably not related to the side chain at position C25 of 16-membered macrocyclic lactone antibiotics. In the efficacy trail of TVM against swine nematodes, growing pigs natural infection of Ascaris suum and Trichuris suis were treated with a single subcutaneous injection 0.3 mg/kg b.w.. Results showed that TVM and IVM had excellent effect in expelling Ascaris suum, and TVM had potential efficacy against Trichuris suis, however IVM had no effect on Trichuris suis. This study suggests that the side chain of TVM at position C25 may have important biological functions, which is one of the key sites of the studies on structure-activity relationship of 16-membered macrocyclic lactone compounds. TVM is a new compound exhibited some advantages worthy of developing. Copyright © 2018 Elsevier B.V. All

    Infected wounds are still one of the great challenges in medicine. In the last decade, it has become increasingly clear that antimicrobial chemotherapy is limited by the spread of antimicrobial resistance. Fortunately, new, highly effective antiseptic substances with a broad antimicrobial spectrum are available, so local treatment is expected to get increasingly more important in wound therapy. This paper reviews the antiseptic agent polihexanide (polyhexamethylene biguanide, PHMB), one of the most promising substances available today, from a clinical point of view, focusing on efficacy, safety and clinical applications.

    Cutaneous bacterial infections are common in children and adults and frequently are caused by Staphylococcus aureus ( S. aureus ). Treatment failures with topical agents are not uncommon and have been shown to be secondary to bacterial resistance. To determine clinical and bacteriological efficacy of retapamulin ointment 1% in treatment of patients with cutaneous bacterial infections caused by methicillin-resistant S. aureus (MRSA) and other bacteria. Prospective, nonrandomized, uncontrolled, open label, single center trial conducted between April 2008 and November 2012 that evaluated efficacy of retapamulin ointment 1% in the treatment of impetigo, folliculitis, and other minor soft tissue infections in children and adults. Fifty patients, who presented to a dermatology outpatient clinic and were clinically diagnosed with impetigo, folliculitis, or minor soft tissue infection suitable for treatment with a topical antibiotic, were screened. Thirty-eight patients were enrolled and received treatment: topical retapamulin ointment 1% twice daily for 5 days. Seven patients were MRSA positive and qualified for the primary efficacy population. One patient withdrew due to an adverse event. Clinical and microbiological exams were performed at baseline and follow-up 5 to 7 days later to assess clinical, microbiological, and therapeutic responses. Primary outcome was clinical response at follow-up in primary efficacy population with MRSA isolated as the baseline pathogen. Secondary outcomes included clinical, microbiologic, and therapeutic responses in patients who were culture positive for any species of bacteria. Clinical response at follow-up in the primary efficacy population (MRSA-positive patients) was not sufficiently powered to demonstrate significance; however, outcomes were excellent, with 7 of 7 patients demonstrating clinical success (5 of 7) or clinical improvement (2 of 7) at follow-up. Barring lack of significance due to small total sample size for patients

    The anticonvulsant activity and safety of imepitoin, a novel antiepileptic drug licensed in the European Union, were evaluated in a multicentre field efficacy study as well as in a safety study under laboratory conditions. Efficacy of imepitoin was compared with phenobarbital in 226 client-owned dogs in a blinded parallel group design. The administration of imepitoin twice daily in incremental doses of 10, 20 or 30 mg/kg demonstrated comparable efficacy to phenobarbital in controlling seizures in dogs. The frequency of adverse events including somnolence/sedation, polydipsia and increased appetite was significantly higher in the phenobarbital group. In phenobarbital-treated dogs, significantly increased levels of alkaline phosphatase, gamma-glutamyl-transferase and other liver enzymes occurred, while no such effect was observed in the imepitoin group. In a safety study under laboratory conditions, healthy beagle dogs were administered 0, 30, 90 or 150 mg/kg imepitoin twice daily for 26 weeks. A complete safety evaluation including histopathology was included in the study. A no-observed-adverse-event level of 90 mg/kg twice daily was determined. These results indicate that imepitoin is a potent and safe antiepileptic drug for dogs. © 2014 The Authors. Journal of Veterinary Pharmacology and Therapeutics Published by John Wiley & Sons Ltd.

    The New York University College of Dentistry has introduced a clinical rotation for fourth-year dental students that focuses on treating people with special health care needs (PSN). The aim of this study was to investigate the hypothesis that clinical experience in treating patients with special health care needs during predoctoral education is associated with increased self-assessed student ability and comfort and therefore self-efficacy. The study also investigated whether other characteristics, such as prior personal or volunteer experience with this population, service-mindedness, and/or the inclination to treat underserved populations, were associated with comfort in treating PSN. A survey was used to assess changes in students' perceived knowledge, beliefs, and attitudes regarding treating PSN before and after the clinical experience for July 2012-June 2013. The survey included questions about students' service-mindedness, comfort, perceptions of abilities of PSN and educational importance of learning to treat PSN, desire for clinical experience, and future intent or interest in treating PSN. Out of 364 students invited to participate, 127 surveys were returned, for a response rate of 34.9%. The results showed statistically significant increases on six items following training: impressions about the importance of oral health among PSN, comfort in treating people with cognitive disabilities and with medical complexities, intent to treat PSN in future practice, interest in including PSN in postgraduate training, and belief that PSN could be treated in the private practice setting. These students reported preferring to learn in the clinical setting over didactic instruction. This clinical experience was associated with improved self-efficacy in treating PSN and increased intentions to treat this population in future practice. Improvements were particularly evident among those with the least prior experience with PSN and were independent of other aspects of the

    The efficacy and tolerability of robenacoxib for the treatment of osteoarthritis in dogs were evaluated in a prospective, multicenter, randomized, noninferiority design clinical trial. A total of 32 dogs presenting with osteoarthritis were allocated randomly to receive, orally once daily for 28 days, either 1-2 mg/kg robenacoxib (n=21) or 3.5-5 mg/kg carprofen (n=11). Dogs were assessed by clinicians and owners using numerical rating scale scores at baseline and days 14 and 28. The primary efficacy endpoint was the global functional disability score, which was the sum of clinician scores for standing posture, lameness at walk, lameness at trot, willingness to raise the contralateral limb and pain at palpation. There was a good to excellent level of efficacy in both treatment groups. Differences between days 14 and 28 compared to day 0 were significant for all 11 clinician and owner scores for robenacoxib, and for 6 of 11 scores for carprofen. The efficacy of robenacoxib was numerically superior to carprofen for all 13 endpoints, but differences were not statistically significant. For the global functional disability score, the estimated efficacy of robenacoxib was 1.244 (95% confidence interval 0.555-2.493) relative to carprofen. The tolerability of both treatments was good as assessed from adverse events, clinical signs, and hematology and serum biochemistry variables. In conclusion, once daily administration of robenacoxib tablets had noninferior efficacy and tolerability compared to carprofen for the treatment of the clinical signs of osteoarthritis in dogs.

    The efficacy of nuclear medicine diagnostic procedures was measured. Three levels of efficacy were defined. However, two different methods of evaluating efficacy itself were first compared. Using two methods, logistic regression and entropy-minimax pattern detection, substantial agreement was found between them in several clinical observations. (1) There are no attributes that indicate that any grouping of symptoms, signs, and laboratory findings is capable of suggesting that a patient does or does not have a pulmonary embolus. (2) The lung scan test is the only reliable method which indicates that a patient may have a pulmonary embolus or does not have a pulmonary embolus. (3) The validity of these conclusions and the ability to apply them widely to ongoing clinical practice is based on the prospective design of the Study which included an appropriate distribution of institutions by type, size, and geographic location. Also, the only judgement samples was that of the referring physician

    To evaluate the short-term efficacy and safety of Bushen Shuji Granule (BSG) in treating ankylosing spondylitis (AS) patients. A prospective randomized controlled clinical trial was carried out in 62 active stage AS patients with Shen deficiency Du-channel cold syndrome (SDDCS), who were randomly assigned to the BSG group (treated with BSG) and the control group (treated with Celecoxib Capsule). Twelve weeks consisted of one therapeutic course. Therapeutic effects were evaluated by ASAS20 and ASAS40 (set by Assessments in Ankylosing Spondylitis working group) , BASDA150, Chinese medical (CM) syndrome efficacy evaluation standards. BASDAI, the Bath Ankylosing Spondylitis Functional Index (BASFI), the Bath AS Metrology Index (BASMI), scores for spine pain, scores for pain at night, patient global assessment (PGA) , erythrocyte sedimentation rate (ESR) , and C reactive protein (CRP) were observed before and after treatment. After three-month treatment by BSG, ASAS20 standard rate was 63. 33% (19/30 cases) in the BSG group and 66.67% (20/30 cases) in the control group with no significant difference between the two groups (χ2 = 0.073, P > 0.05). The efficacy for CM syndromes was 70.00% (21/30 cases) in the BSG group, higher than that in the control group [40.00% (12/30 cases), χ2 = 5.455, P channel strengthening, blood activating, and channels dredging method had good short-term clinical efficacy and safety in treating AS.

    To compare the difference in clinical efficacy on polycystic ovary syndrome (PCOS) between electroacupuncture (EA) and dyne-35 and to explore the effect mechanism. Sixty-five patients were randomized into an EA group (33 cases) and a western medication group (32 cases). In the EA group, the selected acupoints were Danzhong (CV 17), Qimen (LR 14), Zhongwan (CV 12), Tianshu (ST 25), Guanyuan (CV 4), Zigong (EX-CA 1), Sanyinjiao (SP 6), Zusanli (ST 36) and Taichong (LR 3), etc. After the arrival of qi, electric stimulation was attached to the acupoints for 30 min. The treatment was given 3 times a week. In the western medication group, dyne-35 was prescribed on the 5th day of natural menstruation or withdrawal bleeding, one tablet a day, continuously for 21 days. The treatment cycle was 3 months in the two groups. The menstrual condition, body mass, body mass index (BMI), serum testosterone (T), luteinizing hormone (LH), follicle-stimulating hormone (FSH) and LH/FSH were compared before and after treatment in the two groups. The clinical efficacy was assessed in the two groups. The total effective rate was 90.6% (29/32) in the EA group and was 93.3% (28/30) in the western medication group. The efficacy was similar in the two groups (P > 0.05). After treatment, the levels of LH and LH/FSH were all reduced significantly in the two groups (all P medication group (P medication group (P < 0.01, P < 0.05). EA is the effective method for PCOS, similar to that of dyne-35. The effect of it for weight loss is superior to dyne-35 and no apparent adverse reactions happen. The effect mechanism of EA is related to the regulation of serum sexual hormone levels and their ratio, as well as to the regulation of body lipid metabolism.

    Full Text Available The genetic influence of single nucleotide polymorphisms (SNPs on antidepressant efficacy has been previously demonstrated. To evaluate whether there are ethnic differences, we compared the allele frequencies of antidepressant efficacy-related SNPs between the Taiwanese population and four other populations in the HapMap database. We recruited 198 Taiwanese major depression patients and 106 Taiwanese controls. A panel of possible relevant SNPs (in brain-derived neurotrophic factor, 5-hydroxytryptamine receptor 2A, interleukin 1 beta, and G-protein beta 3 subunit genes was selected for comparisons of allele frequencies using the χ2 test. Our results suggested no difference between Taiwanese patients and controls, but there were significant differences among Taiwanese controls and the other four ethnic groups in brain-derived neurotrophic factor, 5-hydroxytryptamine receptor 2A, interleukin 1 beta and G-protein beta 3 subunit genes. We conclude that there are ethnic differences in the allele frequencies of antidepressant efficacy-related SNPs, and that the degree of variations is consistent with geographic distances. Further investigation is required to verify the attribution of genetic differences to ethnic-specific antidepressant responses.

    Full Text Available OBJECTIVE: To assess the efficacy and safety of oral antidiabetic drugs (OADs in gestational diabetes mellitus (GDM in comparison to insulin. METHODS: A meta-analysis of randomized controlled trials was conducted. The efficacy and safety of OADs in comparison to insulin in GDM patients were explored. Studies were identified by conducting a literature search using the electronic databases of Medline, CENTRAL, CINAHL, LILACS, Scopus and Web of Science in addition to conducting hand search of relevant journals from inception until October 2013. RESULTS: Thirteen studies involving 2,151 patients met the inclusion criteria. These studies were randomized controlled trials of metformin and glyburide in comparison to insulin therapy. Our results indicated a significant increase in the risk for preterm births (RR, 1.51; 95% CI, 1.04-2.19, p = 0.03 with metformin compared to insulin. However, a significant decrease in the risk for gestational hypertension (RR, 0.54; 95% CI, 0.31-0.91, p = 0.02 was found. Postprandial glucose levels also decreased significantly in patients receiving metformin (MD, -2.47 mg/dL; 95% CI, -4.00, -0.94, p = 0.002. There was no significant difference between the two groups for the remaining outcomes. There were significant increases in the risks of macrosomia (RR, 2.34; 95% CI, 1.18-4.63, p = 0.03 and neonatal hypoglycemia (RR, 2.06; 95% CI, 1.27-3.34, p = 0.005 in the glyburide group compared to insulin whereas results for the other analyzed outcomes remained non-significant. CONCLUSION: The available evidence suggests favorable effects of metformin in treating GDM patients. Metformin seems to be an efficacious alternative to insulin and a better choice than glyburide especially those with mild form of disease.

    Full Text Available Porcine respiratory disease complex (PRDC is a major economic problem for swine producers world-wide. Pharmacodynamic, pharmacokinetics and clinical efficacy of florfenicol oral formulations in domestic animals were evaluated. For this purpose the systematic review and meta-analysis were done. In vitro efficacy of florfenicol showed that this drug is highly effective against most important respiratory pathogens. All these facts are shown in our survey. Three studies in pigs were relevant to include in the meta-analysis, which showed that results in the florfenicol group were better than in comparative control groups in all observed parameters: clinical signs, lung lesions and resolution of Actinobacillus pleuropneumoniae (P<0,001. A second meta-analysis with 7 studies showed that the usage of florfenicol reduces mortality in pig herds with PRDC (P<0.05. Other field trials in pigs using florfenicol oral forms where reviewed. After treatment with florfenicol oral solution there was a significant drop of mortality in both groups of pigs (P<0.01; eg. one using florfenicol oral solution in treating PRDC (n=85 and another mixed pneumoenteric infection (n=54. Analysis of data when using premix in pigs (n=118 also suggests that a medicated premix has a favorable anti-infectious effect on pigs, irrespective of the group of animals or the evolution stage of the disease. Finally, favorable effect of florfenicol in treating swine ileitis was also presented. Regarding their pharmacokinetics, in vitro and clinical efficacy of florfenicol oral forms, they should be considered as a powerful tool for combating complex infections that are frequently met in intensive animal production.

    Full Text Available The aim of this study was to compare the efficacy of chemochemical methods (Carisolv™ and Papacárie® versus the manual method (excavators in reducing the cariogenic microbiota in dentine caries of primary teeth. Forty-six healthy children (5 to 9 years old having at least one primary tooth with a cavitated dentine carious lesion were included in the study. The teeth presented no clinical or radiographic signs of pulpal involvement. The sample of 74 teeth was randomly divided into three different groups: Papacárie® (n = 25, Carisolv™ (n = 27 and Manual (n = 22. Samples of carious and sound dentine were collected with sterile excavators before and after caries removal in the three groups. The dentine samples were transferred to glass tubes containing a 1mL thioglycollate medium used as a carrier and enriched for microbiological detection of mutans streptococci and Lactobacillus spp, after incubation for 6h at room temperature. The minimum detection value for colony forming units (CFU was 3.3 x 102 CFU/ml, and the results were converted into scores from 0 to 4. A significant difference was observed in relation to the microbiological scores before and after caries removal for all methods (Wilcoxon test; p < 0.001. The use of chemomechanical methods for caries removal did not improve the reduction of cariogenic microorganisms in dentine caries lesions, in comparison with manual excavation.

    The behavioral response to pain is driven by sensory and affective components, each of which is mediated by the CNS. Subjective pain ratings are used as readouts when appraising potential analgesics; however, pain ratings alone cannot enable a characterization of CNS pain circuitry during pain processing or how this circuitry is modulated pharmacologically. Having a more objective readout of potential analgesic effects may allow improved understanding and detection of pharmacological efficacy for pain. The pharmacological/functional magnetic resonance imaging (phMRI/fMRI) methodology can be used to objectively evaluate drug action on the CNS. In this context, we aimed to evaluate two drugs that had been developed as analgesics: one that is efficacious for pain (buprenorphine (BUP)) and one that failed as an analgesic in clinical trials aprepitant (APREP). Using phMRI, we observed that activation induced solely by BUP was present in regions with μ-opioid receptors, whereas APREP-induced activation was seen in regions expressing NK(1) receptors. However, significant pharmacological modulation of functional connectivity in pain-processing pathways was only observed following BUP administration. By implementing an evoked pain fMRI paradigm, these drugs could also be differentiated by comparing the respective fMRI signals in CNS circuits mediating sensory and affective components of pain. We report a correlation of functional connectivity and evoked pain fMRI measures with pain ratings as well as peak drug concentration. This investigation demonstrates how CNS-acting drugs can be compared, and how the phMRI/fMRI methodology may be used with conventional measures to better evaluate candidate analgesics in small subject cohorts.

    Academic procrastination has been seen as an impediment to students' academic success. Research findings suggest that it is related to lower levels of self-regulated learning and academic self-efficacy and associated with higher levels of anxiety, stress, and illness. Emotional intelligence (EI) is the ability to assess, regulate, and utilize emotions and has been found to be associated with academic self-efficacy and a variety of better outcomes, including academic performance. Students with learning disabilities (LD) are well acquainted with academic difficulty and maladaptive academic behavior. In comparison to students without LD, they exhibit high levels of learned helplessness, including diminished persistence, lower academic expectations, and negative affect. This study examined the relationships among academic procrastination, EI, and academic performance as mediated by academic self-efficacy in 287 LD and non-LD students. Results indicated that the indirect effect of EI on academic procrastination and GPA was stronger in LD students than in non-LD students. In addition, results indicated that LD students scored lower than non-LD students on both EI and academic self-efficacy and higher on academic procrastination. No difference was found in GPA.

    Hypotensive anesthesia is crucial during arthroscopic shoulder surgery to reduce bleeding and allow for clear visibility. The aim of this study was to compare the clinical efficacy of continuous infusion of remifentanil, nicardipine, and remifentanil plus nicardipine to control hypotensive anesthesia in arthroscopic shoulder surgery. For this study, we enrolled 45 consecutive patients who were scheduled to have arthroscopic rotator cuff repair surgery and randomly allocated them into remifentanil (group R, n = 15), nicardipine (group N, n = 15), and remifentanil plus nicardipine (group RN, n = 15) groups. During the surgeries, these drugs were administered with continuous infusion. We analyzed the mean arterial pressure (MAP) and heart rate during surgery, stay time in the recovery room, visual analogue scale (VAS) scores, use of antiemetics in the recovery room, and postoperative blood urea nitrogen and creatinine changes. The VAS score in the recovery room was higher for group R (mean 5.6, SD 1.4) than for groups N (mean 3.9, SD 0.9) and RN (mean 4.0, SD 1.1; p = 0.000). There were no statistical differences regarding other clinical variables among the three groups (all p > 0.05) except for MAP at 120 min of surgery between groups N and RN (N: 84.67 (SD 10.7) mmHg, RN: 65.4 (SD 9.2) mmHg, p = 0.027). The continuous infusion of remifentanil plus nicardipine appeared to be advantageous for maintaining hypotensive anesthesia until 120 min of arthroscopic shoulder surgery without rebound pain in a postanesthesia care unit.

    Biotin, also known as Vitamin B7 or vitamin H, is a water-soluble B vitamin that acts as an essential cofactor for several carboxylases involved in the cellular metabolism of fatty acids, amino acids, and gluconeogenesis. Although there exists an incredible amount of social media hype and market advertising touting its efficacy for the improvement of hair quantity and quality, biotin's efficacy for hair remains largely unsubstantiated in scientific literature. We reviewed all pertinent scientific literature regarding the efficacy of biotin supplementation for hair growth and quality improvement, and we also investigated its popularity in society defined as a function of market analytics. To date, there have been no clinical trials conducted to investigate the efficacy of biotin supplementation for the treatment of alopecia of any kind, nor has there been any randomized controlled trial to study its effect on hair quality and quantity in human subjects. Because of the lack of clinical evidence, its use to improve hair quantity or quality is not routinely recommended. However, societal infatuation with biotin supplementation is not only propagated by its glamorization in popular media, its popularity is vastly disproportionate to the insufficient clinical evidence supporting it's efficacy in hair improvement. In other words, biotin supplements are quite "in vogue", without there being any real reason to be so. J Drugs Dermatol. 2017;16(5):496-500..

    Gingivitis affects an estimated 80% of the population, and is characterized as the world's most predominant inflammatory periodontal disease. Without intervention, gingivitis can advance to alveolar bone loss. Therefore, the primary goal in patients suffering with gingivitis is to control plaque buildup and soft tissue inflammation. Current guidelines consider chlorhexidine as the gold standard in the prevention and treatment of gingivitis. However, negative side effects of chlorhexidine, including oral mucosal erosion, discoloration of teeth, and bitter taste, provide an opportunity for alternative medications. Turmeric, a commonly used herb, possesses anti-inflammatory, antioxidant, antibacterial, antiviral, and antifungal properties. By virtue of these properties, multiple controlled trials have been performed to investigate the efficacy of turmeric in gingivitis. The aim of this comprehensive review is to summarize and evaluate the evidence on the efficacy of turmeric as compared to chlorhexidine in the prevention and treatment of gingivitis. PubMed, MedLine (Web of Science), and EBSCO (academic search complete) were utilized as primary literature search tools. The following search strategy was used: ((turmeric OR curcumin OR curcuma) AND (gingivitis OR "gum inflammation")). Five reviewed studies show that both turmeric and chlorhexidine significantly decrease plaque index (PI) and gingival index (GI), and can therefore be used in the prevention and treatment of gingivitis. Both chlorhexidine and turmeric can be used as an adjunct to mechanical means in preventing and treating gingivitis. However, trials longer than 21 days with a greater number of patients are necessary to further evaluate the comparison between turmeric and chlorhexidine. Copyright © 2016 Elsevier Ltd.

    Full Text Available Objective To compare the efficacy of sodium morrhuate versus lauromacrogol in the treatment of hepatic cyst. Methods Seventy-four patients with hepatic cyst who were admitted to our hospital from January 2009 to May 2013 were enrolled as subjects and divided into two groups. After the cystic fluid was drained by percutaneous liver biopsy, sodium morrhuate solution was injected into the cystic cavity for adhesion and sclerosis in 46 patients in group A, and lauromacrogol solution was injected in 28 patients in group B. The incidence rates of pain in patients during and after surgery were compared between the two groups. The follow-up comparison of hepatic cyst recurrence rates within one year after surgery was performed between the two groups. Between-group comparison was performed by χ2 test. Results Five patients (10.87% in group A and two patients (7.14% in group B had recurrence within one year after treatment. There was no significant difference in recurrence rate between the two groups (χ2=0.283, P>0.05. The incidence of pain in group A was significantly higher than that in group B (χ2=5.258, P<0.05. Conclusion With the same efficacy as sodium morrhuate in the treatment of hepatic cyst, lauromacrogol can be routinely used as a sclerosing agent due to its mild side effects.

    Full Text Available BACKGROUND: In East Asia, numerous reports describe the utilization of traditional Chinese herbal decoctions to treat gout. However, the reported clinical effects vary. OBJECTIVES: In this study, we reviewed and analyzed a large number of randomized controlled clinical trials to systematically assess the clinical efficacy and adverse reactions of Chinese herbal decoctions for treating gout. METHODS: We performed a comprehensive search of databases, such as PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, Chinese biomedical literature database, et al. In addition, we manually searched the relevant meeting information in the library of the Third Military Medical University. RESULTS: Finally, 17 randomized controlled trials with a sample size of 1,402 cases met the criteria and were included in the study. The results of the meta-analysis showed that when gout had progressed to the stage of acute arthritis, there was no significant difference in clinical efficacy between Chinese herbal decoctions and traditional Western medicine, as indicated based on the following parameters: serum uric acid (standardized mean difference (SMD:0.35, 95% confidence interval (CI: 0.03 to 0.67, C reactive protein (SMD: 0.25, 95% CI: -0.18 to 0.69, erythrocyte sedimentation rate (SMD: 0.21, 95% CI: -0.02 to 0.45 and overall clinical response (relative risk (RR: 1.05, 95% CI: 1.01 to 1.10. However, the Chinese herbal decoction was significantly better than traditional Western medicine in controlling adverse drug reactions (RR: 0.06, 95% CI: 0.03 to 0.13. CONCLUSIONS: Through a systematic review of the clinical efficacy and safety of Chinese herbal decoctions and traditional Western medicine for the treatment of gout, we found that Chinese herbal decoction and traditional Western medicine led to similar clinical efficacy, but the Chinese herbal decoctions were superior to Western medicine in terms of controlling adverse drug reactions.

    Ketamine has been well studied for its efficacy as an analgesic agent. However, intranasal (IN) administration of ketamine has only recently been studied in the emergency setting. The objective of this study was to elucidate the efficacy and adverse effects of a sub-dissociative dose of IN Ketamine compared to IV and IM morphine. A single-center, randomized, prospective, parallel clinical trial of efficacy and safety of IN ketamine compared to IV and IM morphine for analgesia in the emergency department (ED). A convenience sample of 90 patients aged 18-70 experiencing moderate-severe acute traumatic pain (≥80 mm on 100 mm Visual Analog Scale [VAS]) were randomized to receive either 1.0 mg/kg IN ketamine, 0.1 mg/kg IV MO or 0.15 mg/kg IM MO. Pain relief and adverse effects were recorded for 1 h post-administration. The primary outcome was efficacy of IN ketamine compared to IV and IM MO, measured by "time-to-onset" (defined as a ≥15 mm pain decrease on VAS), as well as time to and degree of maximal pain reduction. The 3 study groups showed a highly significant, similar maximal pain reduction of 56 ± 26 mm for IN Ketamine, and 59 ± 22 and 48 ± 30 for IV MO and IM MO, respectively. IN Ketamine provided clinically-comparable results to those of IV MO with regards to time to onset (14.3 ± 11.2 v. 8.9 ± 5.6 min, respectively) as well as in time to maximal pain reduction (40.4 ± 16.3) versus (33.4 ± 18), respectively. IN ketamine shows efficacy and safety comparable to IV and IM MO. Given the benefits of this mode of analgesia in emergencies, it should be further studied for potential clinical applications.

    Full Text Available Transthoracic echocardiographic examination is known to be a safe, non-invasive and reproducible method, used in every day clinical practice to obtain important information about cardiac structure and function. Unfortunately, a significant proportion of studies have highlighted the considerable technically difficultly in producing diagnostic images due to a poor acoustic window and more than 33% of patients undergoing stress echocardiography have suboptimal echocardiographic images. All these limitations have led to the use of contrast agents to improve the quality of standard ultrasound examination to provide a better delineation of left ventricle endocardial borders or to obtain information that cannot be achieved by using standard echocardiography, such as assessing myocardial microcirculation and therefore perfusion. This paper sought to review the clinical efficacy and safety of ultrasound contrast agents focusing on stress echocardiography.

    Initial approaches for rotavirus vaccines were based on the classical "Jennerian" approach and utilized simian and bovine rotavirus strains, which provided cross-protection against human rotavirus strains but did not cause illness in infants and young children because of their species-specific tropism. The demonstrated efficacy of these vaccines was not consistent across studies. Thus, human-animal reassortants containing an animal rotavirus backbone with human rotavirus surface G and/or P proteins were developed, which demonstrated more consistent efficacy than that observed with the non-reassortant rotavirus strains. The pentavalent rotavirus vaccine, RotaTeq, contains 5 human-bovine reassortant rotaviruses consisting of a bovine (WC3) backbone with human rotavirus surface proteins representative of the most common G (G1, G2, G3, G4) or P (P1A[8]) types worldwide. The present review focuses on the development of the pentavalent rotavirus vaccine RotaTeq. Results of a large-scale Phase III clinical study showed that three doses of RotaTeq were immunogenic, efficacious, and well tolerated with no increased clinical risk of intussusception. RotaTeq was efficacious against rotavirus gastroenteritis of any severity (74%) and severe disease (98-100%), using a validated clinical scoring system. Reductions in rotavirus-associated hospitalizations and emergency department (ED) visits, for up to 2 years post-vaccination, were 95% in Europe, 97% in the United States, and 90% in the Latin American/Caribbean regions. RotaTeq was recently shown to be up to 100% effective in routine use in the US in reducing hospitalizations and ED visits and 96% effective in reducing physician visits. Additional studies in 8 different locations in the US have shown 85-95% reduction in rotavirus-associated hospitalizations and/or ED visits in the first 2-2.5 years of routine use.

Pregabalin, an anticonvulsant and α-2-Δ subunit receptor ligand, is one of the anchor drugs approved by the US Food and Drug Administration for the treatment of fibromyalgia. The drug has shown clinically meaningful benefits across multiple symptom domains of fibromyalgia. Efficacy of pregabalin in fibromyalgia pain has been evaluated in at least five high-quality randomized trials, two long-term extension studies, a meta-analysis, a Cochrane database systematic review, and several post hoc analyses. These studies also hint towards a meaningful benefit on sleep, functioning, quality of life, and work productivity. Side effects of pregabalin, although common, are mild to moderate in intensity. They are noted early during therapy, improve or disappear with dose reduction, and are not usually life- or organ threatening. In most patients, tolerance develops to the most common side effects, dizziness, and somnolence, with time. With close clinical monitoring at initiation or dose titration, pregabalin can be effectively used in primary care setting. Pregabalin is cost saving with long-term use and its cost-effectiveness profile is comparable, if not better, to that of other drugs used in fibromyalgia. In the present era of limited therapeutic options, pregabalin undoubtedly retains its role as one of cardinal drugs used in the treatment of fibromyalgia. This review intends to discuss the clinical utility of pregabalin in the management of fibromyalgia with a focus on efficacy, safety, and cost-effectiveness.

    This paper presents a new method in which the regression velocity of cervical carcinoma is measured by computer tomography and the results evaluated by two statistical methods: non-linear regression analysis and survival analysis. By means of this approach it was possible to compare the early effect of therapy in patients treated with intracavitary application of 226 Ra plus external radiotherapy with those treated with 252 Cf, 226 Ra and extended radiotherapy. In the latter group a higher efficacy of the therapy was demonstrated by both statistical methods. As the timing between external and intracavitary radiotherapy was different in the two groups and as 252 Cf contributed to a rather small part of the total radiation dose it could not be concluded that the difference in efficacy really was due to 252 Cf. Of essential interest was, however, that an obvious difference in efficacy could be found between two slightly different treatment techniques. The statistical procedure called survival analysis, used hereparallely with weighed regression analysis seemed to give better results than a classical regression analysis and can thus be recommended for processing of clinical data of the type which is discussed in this paper.

    Group-based psychosocial programs provide an effective forum for improving mood and social support for cancer patients. Because some studies show more benefit for patients with initially high psychosocial distress, and little or no benefit for patients with initially low distress, support programs may better address patient needs by only including distressed patients. However, distressed patients may benefit particularly from the presence of nondistressed patients who model effective coping, an idea many researchers and extensions of social comparison theory support. We present a theoretical analysis, based on a social comparison perspective, of how group composition (heterogeneous group of distressed and nondistressed patients versus homogeneous group of distressed patients) may affect the efficacy of cancer support programs. We propose that a heterogeneous group allows distressed patients maximal opportunity for the various social comparison activities they are likely to prefer; a homogeneous group does not. Though the presence of nondistressed patients in a heterogeneous group potentially benefits distressed patients, the benefits for nondistressed patients are unclear. For nondistressed patients, heterogeneous groups may provide limited opportunities for preferred social comparison activity and may create the possibility for no benefit or even negative effects on quality of life. We also discuss ethical issues with enrolling nondistressed patients whose presence may help others, but whose likelihood of personal benefit is questionable.

    The combination of gemcitabine and erlotinib is a standard first-line treatment for unresectable, locally advanced or metastatic pancreatic cancer. We reviewed our single centre experience to assess its efficacy and toxicity in clinical practice. Clinical records of patients with unresectable, locally advanced or metastatic pancreatic cancer who were treated with the combination of gemcitabine and erlotinib were reviewed. Univariate survival analysis and multivariate analysis were carried out to indentify independent predictors factors of overall survival. Our series included 55 patients. Overall disease control rate was 47%: 5% of patients presented complete response, 20% partial response and 22% stable disease. Median overall survival was 8.3 months). Cox regression analysis indicated that performance status and locally advanced versus metastatic disease were independent factors of overall survival. Patients who developed acne-like rash toxicity, related to erlotinib administration, presented a higher survival than those patients who did not develop this toxicity. Gemcitabine plus erlotinib doublet is active in our series of patients with advanced pancreatic cancer. This study provides efficacy and safety results similar to those of the pivotal phase III clinical trial that tested the same combination.

    To evaluate the efficacy of tocilizumab (TCZ) in patients with rheumatoid arthritis (RA) in clinical practice, retention rates of the drug and predictors of response. We performed a descriptive, prospective, longitudinal, open-label study in patients receiving TCZ (8mg/kg/4 weeks) in a clinical practice setting. The clinical responses were evaluated using the European League Against Rheumatism (EULAR) response criteria, and the low activity and remission rates according to the Disease Activity Score 28-erythrocyte sedimentation rate (DAS28-ESR) and the Clinical Disease Activity Index (CDAI). The EULAR response rate was 86.63% and the DAS28 remission rate was 53.7% after 6 months of treatment; rates of low disease activity were 52.9% on CDAI and 47.1% on DAS28 at month 24. There were no statistically significant differences in EULAR response, rates of low activity and remission on DAS28 between patients receiving TCZ alone and those receiving TCZ in combination therapy, or between patients positive or negative for rheumatoid factor (RF) and/or anti-cyclic citrullinated peptide (anti-CCP) antibodies. The naïve biological therapy patients showed better remission and low activity rates after 6 months of treatment. The retention rate was 61% at month 24. Adverse events were among the most frequent causes of discontinuation. Tocilizumab is effective in RA, has a similar efficacy when used alone or in combination with synthetic disease-modifying antirheumatic drugs (DMARDs) and shows high retention rates.

    Objectives Despite increasing interest in individual instrument storage, risk of bacterial cross-contamination of otorhinolaryngology clinic instruments has not been assessed. This study is the first to determine the clinical efficacy and cost-effectiveness of standard high-level disinfection and clinic instrument storage. Methods To assess for cross-contamination, surveillance cultures of otorhinolaryngology clinic instruments subject to standard high-level disinfection and storage were obtained at the start and end of the outpatient clinical workday. Rate of microorganism recovery was compared with cultures of instruments stored in individual peel packs and control cultures of contaminated instruments. Based on historical clinic data, the direct allocation method of cost accounting was used to determine aggregate raw material cost and additional labor hours required to process and restock peel-packed instruments. Results Among 150 cultures of standard high-level disinfected and co-located clinic instruments, 3 positive bacterial cultures occurred; 100% of control cultures were positive for bacterial species ( P cost of individual semicritical instrument storage at $97,852.50 per year. Discussion With in vitro inoculation of >200 otorhinolaryngology clinic instruments, this study demonstrates that standard high-level disinfection and storage are equally efficacious to more time-consuming and expensive individual instrument storage protocols, such as peel packing, with regard to bacterial contamination. Implications for Practice Standard high-level disinfection and storage are equally effective to labor-intensive and costly individual instrument storage protocols.

    This study explored the parenting self-efficacy of the parents of 18-month-old children in the context of Finnish maternity and child health clinics. This parenting self-efficacy was observed in relation with the relational continuity of care and parents' experienced loneliness and depressive symptoms. The relational continuity of care was provided by a public health nurse in maternity and child health clinics. The participating parents were drawn from the STEPS study that is being carried out by the Institute for Child and Youth Research at the University of Turku. The results showed that relational continuity of care provided by the same public health nurse in the maternity and child health clinics was associated with mothers' higher emotional loneliness and with lower scores on three dimensions of parents' parenting self-efficacy. Loneliness and depressive symptoms negatively influenced parents' parenting self-efficacy - however, in the case where the family had experienced relational continuity of care, the parents' higher levels of depressive symptoms had not weakened their parenting self-efficacy beliefs. These results are discussed in terms of organizing maternity and child health clinic services. © 2016 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    Clinical scientists frequently need to compare two different bioanalytical methods as part of assay validation/monitoring. As a matter necessity, regression methods for quantitative comparison in clinical chemistry, hematology and other clinical laboratory disciplines must allow for error in both the x and y variables. Traditionally the methods popularized by 1) Deming and 2) Passing and Bablok have been recommended. While commercial tools exist, no simple open source tool is available. The purpose of this work was to develop and entirely open-source GUI-driven program for bioanalytical method comparisons capable of performing these regression methods and able to produce highly customized graphical output. The GUI is written in python and PyQt4 with R scripts performing regression and graphical functions. The program can be run from source code or as a pre-compiled binary executable. The software performs three forms of regression and offers weighting where applicable. Confidence bands of the regression are calculated using bootstrapping for Deming and Passing Bablok methods. Users can customize regression plots according to the tools available in R and can produced output in any of: jpg, png, tiff, bmp at any desired resolution or ps and pdf vector formats. Bland Altman plots and some regression diagnostic plots are also generated. Correctness of regression parameter estimates was confirmed against existing R packages. The program allows for rapid and highly customizable graphical output capable of conforming to the publication requirements of any clinical chemistry journal. Quick method comparisons can also be performed and cut and paste into spreadsheet or word processing applications. We present a simple and intuitive open source tool for quantitative method comparison in a clinical laboratory environment. Copyright © 2014 The Canadian Society of Clinical Chemists.

    Full Text Available Abstract Background The poultry industry due to intensive methods of farming is burdened with losses from numerous infectious agents, of which one is the fungus Aspergillus fumigatus. In a preliminary study, the extracts of Loxostylis alata A. Spreng, ex Rchb. showed good activity in vitro against A. fumigatus with a minimum inhibitory concentration of 0.07 mg/ml. For this study crude, a crude acetone extract of L. alata leaves was evaluated for its acute toxicity in a healthy chicken model and for efficacy in an infectious model of aspergillosis (A. fumigatus. Results At a dose of 300 mg/kg, the extract induced some toxicity characterised by decreased feed intake and weight loss. Consequently, 100 and 200 mg/kg were used to ascertain efficacy in the infectious model. The plant extract significantly reduced clinical disease in comparison to the control in a dose dependant manner. The extract was as effective as the positive control ketoconazole dosed at 60 mg/kg. Conclusions The results indicate that a crude extract of L. alata leaves has potential as an antifungal agent to protect poultry against avian aspergillosis.

    Evidence for the efficacy of antimicrobial treatments in Escherichia coli mastitis is limited. The aim of this double-blinded field trial was to investigate the efficacy of enrofloxacin compared with placebo, with a special focus on survival, in dairy cows with acute clinical mastitis caused by E. coli. Dairy cows (n=116) with acute clinical mastitis were included in the study. A clinical examination was performed and a milk sample from the affected udder quarter was collected for investigation of somatic cell count (SCC) and bacteriology on the first day of treatment (day 0) and at day 3 (clinical examination only), day 22 and day 28. Data regarding culled cows, SCC and daily milk yield were retrieved from monthly milk recording each month until 180 days after treatment. All cows were treated with either enrofloxacin or placebo once a day for three days, starting at day 0. After culturing, 56 cows with confirmed E. coli mastitis remained in the study. Nine (16 per cent) of them died within the first week. Enrofloxacin-treated cows had lower SCC compared with placebo-treated cows at first monthly milk recordings after being treated for mastitis. Treatment with enrofloxacin did not result in a higher probability of survival compared with placebo. British Veterinary Association.

    To study the efficacy of Viagra combined with behavior therapy against premature ejaculation (PE). Sixty PE patients were divided into two groups randomly: control group (behavior therapy alone) and the group of Viagra combined with behavior therapy. Intra-vaginal ejaculation latency time (IELT) and the coitus satisfaction of the patient and the partner were recorded before and after treatment. The IELTs of the two groups were 0.80 +/- 0.20 and 0.73 +/- 0.24 minutes respectively before treatment, and 1.82 +/- 0.54 and 3.63 +/- 0.55 minutes respectively after treatment. As for IELT and satisfaction degree, Viagra produced better result than behavior therapy. During this clinical trial, Viagra combined with behavior therapy prolonged IELT, which suggests that Viagra may be helpful for the treatment of premature ejaculation.

    Full Text Available Objective. Despite the systematic literature review of the current evidence, we aim to answer the question “ is Deqi an indicator of clinical effects in acupuncture treatment?” Methods. We systematically searched CNKI, VIP, Wanfang Data, PubMed, Embase, and the CENTRAL for three types of study: (1 empirical research probing into the role of Deqi in acupuncture; (2 mechanism studies examining the effect of Deqi on physiological parameters in animal models and human subjects; (3 clinical studies that compared the outcome of acupuncture with Deqi with that of acupuncture without Deqi. Two reviewers independently extracted data, undertook qualitative or quantitative analysis, and summarized findings. Results. The ancient Chinese acupuncturists valued the role of Deqi as a diagnostic tool, a prognosis predictor, and a necessary part of the therapeutic procedure. Findings from modern experimental research provided preliminary evidence for the physiological mechanism that produced Deqi. Few clinical studies generated conflicting evidence of the comparative effectiveness of acupuncture with Deqi versus acupuncture without Deqi for a variety of conditions. Conclusion. The current evidence base is not solid enough to draw any conclusion regarding the predicative value of natural Deqi for clinical efficacy or the therapeutic value of manipulation-facilitated Deqi.

BRV is a selective, high-affinity ligand for synaptic vesicle 2A (SV2A with 15- to 30-fold higher affinity than levetiracetam, the first AED acting on SV2A. It has high lipid solubility and rapid brain penetration, with engagement of the target molecule, SV2A, within minutes of administration. BRV has potent broad-spectrum antiepileptic activity in animal models. Phase I studies indicated BRV was well tolerated and showed a favorable pharmacokinetic profile over a wide dose range following single (10–1,000 mg and multiple (200–800 mg/day oral dosing. Three pivotal Phase III studies have demonstrated promising efficacy and a good safety and tolerability profile across doses of 50–200 mg/day in the adjunctive treatment of refractory focal seizures. Long-term data indicate that the response to BRV is sustained, with good tolerability and retention rate. BRV is highly effective in patients experiencing secondarily generalized tonic–clonic seizures. Safety data to date suggest a favorable psychiatric adverse effect profile in controlled studies, although limited postmarketing data are available. BRV is easy to use, with no titration and little drug–drug interaction. It can be initiated at target dose with no titration. Efficacy is seen on day 1 of oral use in a significant percentage of patients. Intravenous administration in a 2-minute bolus and 15-minute infusion is well tolerated. Here, we review the pharmacology, pharmacokinetics, and clinical data of BRV. Keywords: brivaracetam, efficacy

    Bright light therapy (BLT) is an effective treatment for seasonal affective disorder and non- seasonal depression. The efficacy of BLT in treating patients with bipolar disorder is still unknown. The aim of this study is to examine the efficacy, onset time and clinical safety of BLT in treating patients with acute bipolar depression as an adjunctive therapy (trial registration at ClinicalTrials.gov: NCT02009371). This was a multi-center, single blind, randomized clinical trial. Seventy-four participants were randomized in one of two treatment conditions: BLT and control (dim red light therapy, dRLT). Sixty-three participants completed the study (33 BLT, 30 dRLT). Light therapy lasted for two weeks, one hour every morning. All participants were required to complete several scales assessments at baseline, and at the end of weeks 1 and 2. The primary outcome measures were the clinical efficacy of BLT which was assessed by the reduction rate of HAMD-17 scores, and the onset time of BLT which was assessed by the reduction rate of QIDS-SR16 scores. The secondary outcome measures were rates of switch into hypomania or mania and adverse events. 1) Clinical efficacy: BLT showed a greater ameliorative effect on bipolar depression than the control, with response rates of 78.19% vs. 43.33% respectively (p < 0.01). 2) Onset day: Median onset day was 4.33 days in BLT group. 3) BLT-emergent hypomania: No participants experienced symptoms of hypomania. 4) Side effects: No serious adverse events were reported. BLT can be considered as an effective and safe adjunctive treatment for patients with acute bipolar depression. Copyright © 2017 Elsevier B.V. All rights reserved.

    A new, more palatable formulation of 10% enrofloxacin enteric-coated granules was investigated to evaluate the pharmacokinetic effect in plasma, the residue elimination in tissues and the clinical efficacy against Actinobacillus pleuropneumonia (APP) and Mycoplasam suis (MS) in pigs. In this study, the enrofloxacin concentrations in plasma and tissues were detected using high-performance liquid chromatography with phosphate buffer (pH = 3) and acetonitrile. The pharmacokinetics and elimination of enrofloxacin enteric-coated granules were performed after oral administration at a single dose of 10 mg/kg body weight (bw) and 5 mg/kg twice per day for 5 consecutive days, respectively. The in vivo antibacterial efficacy and clinical effectiveness of enrofloxacin enteric-coated granules against APP and MS were assayed at 2.5, 5, 10 mg/kg, compared with tiamulin (8 mg/kg) based on establishment of APP and MS infection models. 56 APP strains were selected and tested for in vitro antibacterial activity of enrofloxacin enteric-coated granules. The main parameters of elimination half-life (t 1/2β ), T max , and area under the curve (AUC) were 14.99 ± 4.19, 3.99 ± 0.10, and 38.93 ± 1.52 μg h/ml, respectively, revealing that the enrofloxacin concentration remained high and with a sustainable distribution in plasma. Moreover, the analysis on the evaluation of enrofloxacin and ciprofloxacin in muscle, fat, liver and kidney showed that the recovery were more than 84% recovery in accordance with the veterinary drug residue guidelines of United States pharmacopeia, and the withdrawal periods were 4.28, 3.81, 4.84, and 3.51 days, respectively, suggesting that the withdrawal period was 5 d after oral administration of 5 mg/kg twice per day. The optimal dosage of enrofloxacin enteric-coated granules against APP and MS was 5 mg/kg, with over 90% efficacy, which was significantly different ( p enrofloxacin enteric-coated granules had significant potential for treating APP and MS

    Being exposed to good teachers has been shown to enhance students' knowledge and their clinical performance, but little is known about the underlying psychological mechanisms that provide the basis for being an excellent medical teacher. Self-Determination Theory (SDT) postulates that more self-regulated types of motivation are associated with higher performance. Social Cognitive Theory (SCT) focuses on self-efficacy that has been shown to be positively associated with performance. To investigate the influences of different types of teaching motivation, teaching self-efficacy, and teachers' perceptions of students' skills, competencies and motivation on teaching quality. Before the winter semester 2014, physicians involved in bedside teaching in internal medicine at the University Medical Center Hamburg-Eppendorf completed a questionnaire with sociodemographic items and instruments measuring different dimensions of teaching motivation as well as teaching self-efficacy. During the semester, physicians rated their perceptions of the participating students who rated the teaching quality after each lesson. We performed a random intercept mixed-effects linear regression with students' ratings of teaching quality as the dependent variable and students' general interest in a subject as covariate. We explored potential associations between teachers' dispositions and their perceptions of students' competencies in a mixed-effects random intercept logistic regression. 94 lessons given by 55 teachers with 500 student ratings were analyzed. Neither teaching motivation nor teaching self-efficacy were directly associated with students' rating of teaching quality. Teachers' perceptions of students' competencies and students' general interest in the lesson's subject were positively associated with students' rating of teaching quality. Physicians' perceptions of their students' competencies were significantly positively predicted by their teaching self-efficacy. Teaching quality

    The comparative efficacy and safety profiles of selected daily 1000 IU, weekly 7000 IU and monthly 30,000 IU vitamin D 3 -not previously investigated-will be evaluated. Here, a prospective, randomized clinical trial, comparing efficacy and safety of a daily single dose of 1000 IU (group A) to a once-weekly 7000 IU dose (group B), or monthly 30,000 IU dose (group C) of vitamin D 3 . The present study is a controlled, randomized, open-label, multicenter clinical trial, 3  months in duration. Sixty-four adult subjects with vitamin D deficiency (25OHD<20 ng/ml), were included according to the inclusion and exclusion criteria. Dose-responses for increases in serum vitamin 25OHD were statistically equivalent for each of the three groups: A, B and C. Outcomes were 13.0 ± 1.5; 12.6 ± 1.1 and 12.9 ± 0.9 ng/ml increases in serum 25OHD per 1000 IU, daily, weekly and monthly, respectively. The treatment of subjects with selected doses restored 25OHD values to levels above 20 ng/ml in all groups. Treatment with distinct administration frequency of vitamin D 3 did not exhibit any differences in safety parameters. The daily, weekly and monthly administrations of daily equivalent of 1000 IU of vitamin D 3 provide equal efficacy and safety profiles.

    Full Text Available Corneal cross-linking (CXL is a noninvasive therapeutic procedure for keratoconus that is aimed at improving corneal biomechanical properties by induction of covalent cross-links between stromal proteins. It is accomplished by ultraviolet A (UVA radiation of the cornea, which is first saturated with photosensitizing riboflavin. It has been shown that standard epithelium-off CXL (S-CXL is efficacious, and it has been recommended as the standard of care procedure for keratoconus. However, epithelial removal leads to pain, transient vision loss, and a higher risk of corneal infection. To avoid these disadvantages, transepithelial CXL was developed. Recently, iontophoresis has been adopted to increase riboflavin penetration through the epithelium. Several clinical observations have demonstrated the safety and efficacy of iontophoresis-assisted epithelium-on CXL (I-CXL for keratoconus. This review aimed to provide a comprehensive summary of the published studies regarding I-CXL and a comparison between I-CXL and S-CXL. All articles used in this review were mainly retrieved from the PubMed database. Original articles and reviews were selected if they were related to the I-CXL technique or related to the comparison between I-CXL and S-CXL.

    H1-antihistamines are recommended as the first-line symptomatic treatment of allergic rhinitis. The objective of this study was to evaluate the effects of rupatadine (RUP) versus desloratadine (DES) in subjects with seasonal allergic rhinitis (SAR). To assess the efficacy and safety of RUP in SAR in comparison with placebo (PL) and DES. A randomized, double-blind, multicenter, international, and PL-controlled study was carried out. The main selection criteria included SAR patients over 12 years old with a positive prick test to a relevant seasonal allergen for the geographic area. Symptomatic patients at screening with a nasal symptom sum score of ≥6 points (nasal discharge, nasal obstruction, sneezing, and nasal pruritus), a non-nasal score of ≥3 points (ocular pruritus, ocular redness, and tearing eyes), and a rhinorrhea score of ≥2 points with laboratory test results and electrocardiography within acceptable limits were included in the study. Change from baseline in the total symptom-score (T7SS) over the 4-week treatment period (reflective evaluation) was considered the primary efficacy variable. Secondary efficacy measures included total nasal symptom score (T4NSS) and conjunctival symptom score (T3NNSS), both of which are reflective and instantaneous evaluations. Furthermore questions related to quality of life (eg, sleep disturbances or impairment of daily activities) have also been evaluated. Safety was assessed according to adverse events reported, as well as laboratory and electrocardiography controls. A total of 379 patients were randomized, of which 356 were included and allocated to PL (n = 122), RUP (n = 117), or DES (n = 117). Mean change of T7SS over the 4-week treatment period was significantly reduced in the RUP (-46.1%, P = 0.03) and DES (-48.9%, P = 0.01) groups, compared with PL. Similarly, RUP and DES were comparable and significantly superior to PL for all secondary endpoints, including nasal and conjunctival symptoms and patients' and

    To demonstrate the effectiveness of endovascular treatment (EVT) with self-expandable bare stents for malignant superior vena cava syndrome (SVCS) and to analyze predictive factors of EVT efficacy. Retrospective review of the 164 patients with malignant SVCS treated with EVT in our hospital from August 1992 to December 2007 and followed until February 2009. Endovascular treatment includes angioplasty before and after stent placement. We used self-expandable bare stents. We studied results of this treatment and looked for predictive factors of clinical efficacy, recurrence, and complications by statistical analysis. Endovascular treatment was clinically successful in 95% of cases, with an acceptable rate of early mortality (2.4%). Thrombosis of the superior vena cava was the only independent factor for EVT failure. The use of stents over 16 mm in diameter was a predictive factor for complications (P = 0.008). Twenty-one complications (12.8%) occurred during the follow-up period. Relapse occurred in 36 patients (21.9%), with effective restenting in 75% of cases. Recurrence of SVCS was significantly increased in cases of occlusion (P = 0.01), initial associated thrombosis (P = 0.006), or use of steel stents (P = 0.004). Long-term anticoagulant therapy did not influence the risk of recurrence or complications. In malignancy, EVT with self-expandable bare stents is an effective SVCS therapy. These results prompt us to propose treatment with stents earlier in the clinical course of patients with SVCS and to avoid dilatation greater than 16 mm.

Thrombosis of the superior vena cava was the only independent factor for EVT failure. The use of stents over 16 mm in diameter was a predictive factor for complications (P = 0.008). Twenty-one complications (12.8%) occurred during the follow-up period. Relapse occurred in 36 patients (21.9%), with effective restenting in 75% of cases. Recurrence of SVCS was significantly increased in cases of occlusion (P = 0.01), initial associated thrombosis (P = 0.006), or use of steel stents (P = 0.004). Long-term anticoagulant therapy did not influence the risk of recurrence or complications. In malignancy, EVT with self-expandable bare stents is an effective SVCS therapy. These results prompt us to propose treatment with stents earlier in the clinical course of patients with SVCS and to avoid dilatation greater than 16 mm.

    With depression known to impede HIV care adherence and retention, we examined whether depression alleviation improves these disease management behaviors. A sample of 1028 depressed HIV clients in Uganda enrolled in a cluster randomized controlled trial of two depression care models, and were surveyed over 12 months. Serial regression analyses examined whether depression alleviation was associated with self-reported antiretroviral therapy (ART) adherence and clinic attendance at month 12, and whether these relationships were mediated by self-efficacy and motivation. Among those with major depression, depression alleviation was associated with better ART adherence and clinic attendance at month 12; these relationships were fully mediated by self-efficacy at month 12, while adherence motivation partially mediated the relationship between depression alleviation and ART adherence. When both mediators were entered simultaneously, only self-efficacy was a significant predictor and still fully mediated the relationship between depression alleviation and adherence. These findings suggest that depression alleviation benefits both ART adherence and clinic attendance, in large part through improved confidence and motivation to engage in these disease management behaviors.

    Due to the scarcity of cross-cultural comparative studies in exploring students' self-efficacy in science learning, this study attempted to develop a multi-dimensional science learning self-efficacy (SLSE) instrument to measure 316 Singaporean and 303 Taiwanese eighth graders' SLSE and further to examine the differences between the two student groups. Moreover, within-culture comparisons were made in terms of gender. The results showed that, first, the SLSE instrument was valid and reliable for measuring the Singaporean and Taiwanese students' SLSE. Second, through a two-way multivariate analysis of variance analysis (nationality by gender), the main result indicated that the SLSE held by the Singaporean eighth graders was significantly higher than that of their Taiwanese counterparts in all dimensions, including 'conceptual understanding and higher-order cognitive skills', 'practical work (PW)', 'everyday application', and 'science communication'. In addition, the within-culture gender comparisons indicated that the male Singaporean students tended to possess higher SLSE than the female students did in all SLSE dimensions except for the 'PW' dimension. However, no gender differences were found in the Taiwanese sample. The findings unraveled in this study were interpreted from a socio-cultural perspective in terms of the curriculum differences, societal expectations of science education, and educational policies in Singapore and Taiwan.

    Full Text Available Introduction: Clinical trials of acupuncture not always have concordant results, mostly due to their great heterogeneity. Two indexes have been developed to analyze the quality of acupuncture trials. This study hypothesizes that, the more adequate the intervention and the control techniques, the more efficacious the acupuncture. Methods: Both indexes were applied to 27 randomized clinical trials comparing acupuncture to placebo. Results were compared by using the Mann-Whitney test. Results: Studies favorable to acupuncture had a intervention score’s median of 11.5; for the unfavorable ones, it was 7, p: 0.0017. Articles with and without statistically significant differences, though, had the same median for their scores in the control index: 6. Discussion: There is a positive relation between a better score for acupuncture technique and a statistically significant difference between acupuncture and interventional control. However, due to the little heterogeneity in the degree of physiological effect from each article, the control index had no statistical significance. Conclusion: This study established that, among acupuncture RCT controlled by placebo or sham of moderate physiological effect, the adequacy of the technique is more important than the adequacy of control in establishing a statistically significant difference between acupuncture and interventional control.

    Background: Many attempts have been made to abbreviate mindfulness programmes in order to make them more accessible for general and clinical populations while maintaining their therapeutic components and efficacy. The aim of this study was to assess the efficacy of an 8-week mindfulness-based intervention (MBI) programme and a 4-week abbreviated version for the improvement of well-being in a non-clinical population. Method: A quasi-experimental, controlled, pilot study was conducted with pre-post and 6-month follow-up measurements and three study conditions (8- and 4-session MBI programmes and a matched no-treatment control group, with a sample of 48, 46, and 47 participants in each condition, respectively). Undergraduate students were recruited, and mindfulness, positive and negative affect, self-compassion, resilience, anxiety, and depression were assessed. Mixed-effects multi-level analyses for repeated measures were performed. Results: The intervention groups showed significant improvements compared to controls in mindfulness and positive affect at the 2- and 6-month follow-ups, with no differences between 8- vs. 4-session programmes. The only difference between the abbreviated MBI vs. the standard MBI was found in self-kindness at 6 months, favoring the standard MBI. There were marginal differences in anxiety between the controls vs. the abbreviated MBI, but there were differences between the controls vs. the standard MBI at 2- and 6-months, with higher levels in the controls. There were no differences in depression between the controls vs. the abbreviated MBI, but differences were found between the controls vs. the standard MBI at 2- and 6-months, favoring the standard MBI. There were no differences with regard to negative affect and resilience. Conclusion: To our knowledge, this is the first study to directly investigate the efficacy of a standard 8-week MBI and a 4-week abbreviated protocol in the same population. Based on our findings, both programmes

    Since the introduction of the first gadolinium-based contrast agent (Gd-CA) in 1988 it has become clear that these agents significantly improve the diagnostic efficacy of MRI. Studies on single agents have shown that, in comparison to unenhanced sequences, all agents help to improve the detection and delineation of lesions which can alter diagnosis in up to 40% of patients. Doubling or tripling the standard dose of 0.1 mmol/kg body weight may be beneficial for selected indications (e.g. brain perfusion, equivocal single dose study in MRI for brain metastasis, small vessel MR angiography). A more limited number of studies have compared the various agents. These studies do not show clinically significant differences in diagnostic efficacy between the various extracellular Gd-CA. Agents with higher concentration or protein binding may be relatively better suitable for selected applications (e.g. perfusion MRI). The higher relaxivity agents may be used in somewhat lower doses than the extracellular agents.

    We evaluated the long-term efficacy of raltegravir according to HIV-1 subtype (B and non-B) using data from three phase III studies in treatment-experienced (BENCHMRK-1 and 2) and treatment-naive (STARTMRK) HIV-infected patients. HIV-1 subtypes were identified from baseline plasma specimens using genotypic data of the PhenoSense GT test (Monogram Biosciences, South San Francisco, California, USA). Non-B subtypes were combined for the current analyses due to small numbers of each specific subtype. An observed failure approach was used (only discontinuations due to lack of efficacy were treated as failures). Resistance evaluation was performed in patients with documented virologic failure. Seven hundred and forty-three patients received raltegravir and 519 received comparator (efavirenz in STARTMRK; optimized background therapy in BENCHMRK). Non-B subtype virus (A, A/C, A/D, A/G, A1, AE, AG, B/G, BF, C, D, D/F, F, F1, G, and complex) was isolated at baseline in 98 (13%) raltegravir recipients and 62 (12%) comparator recipients. Subtypes AE and C were most common, isolated in 41 and 43 patients, respectively. The proportion of raltegravir recipients achieving HIV RNA less than 50 copies/ml was similar between non-B and B subtypes (STARTMRK: 94.5 vs. 88.7%; BENCHMRK-1 and 2: 66.7 vs. 60.7%); change in CD4 cell count also was similar between non-B and B subtypes (STARTMRK: 243 vs. 221 cells/μl; BENCHMRK-1 and 2: 121 vs. 144 cells/μl). Phenotypic resistance to raltegravir in non-B virus was associated with integrase mutations observed previously in subtype B virus. In phase III studies in treatment-naive and treatment-experienced patients, raltegravir showed comparable and potent clinical efficacy against B and non-B HIV-1 subtypes.

    Full Text Available The clinical efficacy of tulathromycin (TU and florfenicol (FL in the treatment of bronchopneumonia (BP caused by Pasteurella multocida which was isolated from nose swabs of diseased calves has been examined. The symptoms of bronchopneumonia (BP were quantified by means of the clinical score (CS with a maximum of 47 points. In the current investigation the average CS in diseased calves was 23.5± 0.15. The clinical efficacy of TU and FL was assessed every day in the first week after the administration of the drugs and was based on the decrease in CS and on microbiological findings on days 7, 28 and 35 after the completion of therapy. Tulathromycin was administered s.c., in the prescribed therapeutic dose (2.5 mg/kg BW, and florfenicol s.c., twice at a 48 h interval, in its respective therapeutic dose (40 mg/kg BW. In spite of the repeated administration of FL, TU was significantly more rapid to decrease the major clinical symptoms in the first four days following the application, in comparison with FL (P<0.05. On the fourth day after the administration, the clinical efficacy of TU in the therapy of BP in calves was 43.4±1.5 %, and of florfenicol 27.2±1.6 %. However, five days after the application of TU and two days after the repeated application of FL the assessed clinical efficacy of the two antibiotics was roughly the same. The average efficacy of TU was 57.1±0.0%, and of florfenicol 58.5±0.0%, both the individual and mean CS in the treated calves was 10 points, due to hyperthermia, which remained the only symptom. Six days after the administration of TU and three days after the repeated application of FL both antibiotics had equal maximum efficacy (100% in the treatment of BP. The clinical efficacy remained unchanged on day seven. The recovery was confirmed by the absence of P. multocida in nose swabs sampled on the seventh day after the initial treatment. However, in 4 calves (21.05 % of the 19 treated Streptococcus alpha haemolyticus

    Randomised placebo-controlled trials investigating treatments for bipolar disorder have been hampered by wide variations of active drugs and placebo clinical response rates. It is important to estimate whether the active drug or placebo response has a greater influence in determining the relative efficacy of drugs for psychosis (antipsychotics) and relapse prevention (mood stabilisers) for bipolar depression and mania. We identified 53 randomised, placebo-controlled trials assessing antipsychotic or mood stabiliser monotherapy ('active drugs') for bipolar depression or mania. We carried out random-effects meta-regressions, estimating the influence of active drugs and placebo response rates on treatment relative efficacy. Meta-regressions showed that treatment relative efficacy for bipolar mania was influenced by the magnitude of clinical response to active drugs ( p=0.002), but not to placebo ( p=0.60). On the other hand, treatment relative efficacy for bipolar depression was influenced by response to placebo ( p=0.047), but not to active drugs ( p=0.98). Despite several limitations, our unexpected findings showed that antipsychotics / mood stabilisers relative efficacy for bipolar depression seems unrelated to active drugs response rates, depending only on clinical response to placebo. Future research should explore strategies to reduce placebo-related issues in randomised, placebo-controlled trials for bipolar depression.

    Objective: To compare antibiotic therapy and appendectomy in uncomplicated acute appendicitis in terms of efficacy. Study Design: Randomized controlled trial. Place and Duration of Study: Surgical Ward Forward Treatment Centre (FTC), 5 Mountain Medical Battalion Forward Kahuta Azad Jammu Kashmir (AJK), from Oct 2011 to Mar 2013. Material and Methods: A total of 103 patients with clinical diagnosis of acute appendicitis (AA) were admitted during the duration of study and divided into two groups by consecutive sampling. The antibiotic group consisted of 51 patients who received intravenous antibiotics for 48 hours and oral antibiotics for another 8 days. The appendectomy group comprised of 52 patients who all underwent standard appendectomy. All the patients were followed up at 1 month and 1 year for assessing efficacy and post treatment complications. Results: The efficacy of antibiotic treatment is 90.625 percent as compared to appendectomy which was 88.46 percent (p=0.759) at 1 month follow up after treatment. At one year post treatment, the comparison between the efficacy of antibiotic therapy (71.87 percent) and appendectomy (87.14 percent) remains statistically insignificant (p=0.055). Conclusion: Antibiotic therapy is comparable to appendectomy in AA in terms of efficacy at 1 month and 1 year post treatment. (author)

    Full Text Available Gait disorder, a key contributor to fall and poor quality of life, represents a major therapeutic challenge in Parkinson's disease (PD. The efficacy of acupuncture for PD remains unclear, largely due to methodological flaws and lack of studies using objective outcome measures.To objectively assess the efficacy of electroacupuncture (EA for gait disorders using body-worn sensor technology in patients with PD.In this randomized pilot study, both the patients and assessors were masked. Fifteen PD patients were randomly assigned to an experimental group (n = 10 or to a control group (n = 5. Outcomes were assessed at baseline and after completion of three weekly EA treatments. Measurements included gait analysis during single-task habitual walking (STHW, dual-task habitual walking (DTHW, single-task fast walking (STFW, dual-task fast walking (DTFW. In addition, Unified Parkinson's Disease Rating Scale (UPDRS, SF-12 health survey, short Falls Efficacy Scale-International (FES-I, and visual analog scale (VAS for pain were utilized.All gait parameters were improved in the experimental group in response to EA treatment. After adjustment by age and BMI, the improvement achieved statistical significant level for gait speed under STHW, STFW, and DTFW (9%-19%, p0.110. The highest correlation between gait parameters and UPRDS scores at baseline was observed between gait speed during STFW and UPDRS II (r = -0.888, p = 0.004. The change in this gait parameter in response to active intervention was positively correlated with baseline UPDRS (r = 0.595, p = 0.057. Finally, comparison of responses to treatment between groups showed significant improvement, prominently in gait speed (effect size 0.32-1.16, p = 0.001.This study provides the objective proof of concept for potential benefits of non-pharmaceutical based EA therapy on enhancing gait in patients with PD.ClinicalTrials.gov NCT02556164.

    Vaginal infection and inflammation with or without vulvar involvement are very common gynecologicaly clinical conditions associated with morbidity and reduced quality of life. Vaginal infections are commonly treated with causal antimicrobial treatments. In addition to specific antimicrobial treatment, anti-inflammatory therapy, both systemic or topical (vaginal douche), could be useful in the integrated treatment approach of these conditions reducing symptoms and speeding up the recovery in vulvovaginitis. Ibuprofen is a well-known effective and well-tolerated anti-COX (anti-COX1 and COX2) compound. In addition, several in vitro studies suggest that Ibuprofen shares antimicrobial and antifungal activities. Ibuprofen isobutanolammonium (Ib-isb) (Ginenorm) is a soluble salt from formulation suitable for external and intravaginal use. This salt completely dissociates in aqueous solution. Ib-isob is available in sachet and vaginal douche pharmaceutical formulations. Clinical efficacy of Ib-isob has been documented in 10 clinical studies (6 controlled and 4 open trials) which have enrolled in total 399 women with vulvovaginitis. The six controlled clinical trials were performed both versus placebo (2 studies) or versus active comparators such as benzydamine. In these studied, Ib-Isb has been used in general for 7 consecutive days with a twice application daily regimen at the dose of 1 g per application. Topical application of Ib-isob induced a marked and rapid reduction in signs (erythema, oedema) and symptoms (itching and burning sensation) of vulvovaginitis. In head-to-head studies carried out in comparison with other topical products, Ib-isob induced a more rapid reduction in both subjective and objective symptoms. In particular a remarkable significant improvement of all the symptoms has been observed in the group of patients treated with Ib-isob in comparison with women receiving benzydamine. The clinical data available for Ib-isob confirm that this salt

    The objective of this study was to assess the efficacy of botulinum toxins on bruxism. Electronic databases (PubMed, Embase and Science Citation Index), websites (Cochrane Central Register of Controlled Trials and ClinicalTrials.gov) and the literature database of SIGLE (System for Information on Grey Literature in Europe) were searched from January 1990 to April 2011 for randomised controlled trials or nonrandomised studies assessing the efficacy of botulinum toxins on bruxism. There was no language restriction. Through a predefined search strategy, we retrieved 28 studies from PubMed, 94 from Embase, 60 from the Science Citation Index, two ongoing clinical trials and two from the Cochrane Central Register of Controlled Trials. Of these, only four studies met our inclusion criteria and were finally included. Of the four included studies, two were randomised controlled trials and two were controlled before-and-after studies. These studies showed that botulinum toxin injections can reduce the frequency of bruxism events, decrease bruxism-induced pain levels and satisfy patients' self-assessment with regard to the effectiveness of botulinum toxins on bruxism. In comparison with oral splint, botulinum toxins are equally effective on bruxism. Furthermore, botulinum toxin injections at a dosage of bruxism and are safe to use. Therefore, they can be used clinically for otherwise healthy patients with bruxism. © 2012 FDI World Dental Federation.

    Full Text Available The only licensed vaccine against tuberculosis (TB, bacille Calmette–Guérin (BCG, protects against severe extrapulmonary forms of TB but is virtually ineffective against the most prevalent form of the disease, pulmonary TB. BCG was genetically modified at the Max Planck Institute for Infection Biology to improve its immunogenicity by replacing the urease C encoding gene with the listeriolysin encoding gene from Listeria monocytogenes. Listeriolysin perturbates the phagosomal membrane at acidic pH. Urease C is involved in neutralization of the phagosome harboring BCG. Its depletion allows for rapid phagosome acidification and promotes phagolysosome fusion. As a result, BCGΔureC::hly (VPM1002 promotes apoptosis and autophagy and facilitates release of mycobacterial antigens into the cytosol. In preclinical studies, VPM1002 has been far more efficacious and safer than BCG. The vaccine was licensed to Vakzine Projekt Management and later sublicensed to the Serum Institute of India Pvt. Ltd., the largest vaccine producer in the world. The vaccine has passed phase I clinical trials in Germany and South Africa, demonstrating its safety and immunogenicity in young adults. It was also successfully tested in a phase IIa randomized clinical trial in healthy South African newborns and is currently undergoing a phase IIb study in HIV exposed and unexposed newborns. A phase II/III clinical trial will commence in India in 2017 to assess efficacy against recurrence of TB. The target indications for VPM1002 are newborn immunization to prevent TB as well as post-exposure immunization in adults to prevent TB recurrence. In addition, a Phase I trial in non-muscle invasive bladder cancer patients has been completed, and phase II trials are ongoing. This review describes the development of VPM1002 from the drawing board to its clinical assessment.

    Full Text Available Abstract: Topical retinoids are considered as the first line therapy in the treatment of acne vulgaris, but they are associated with cutaneous irritation. In this study, isotretinoin-loaded solid lipid nanoparticles(IT-SLN were prepared to treat the mild to moderate acne. Also using IT-SLN would minimize IT adverse effects in comparison to commercial product, Isotrex®. This study was conducted to prepare and characterize IT-SLN and assessing the efficiency of IT-SLN comparing to Isotrex® acne. IT-SLN was prepared using hot high pressure homogenization method.  IT-SLN contained 0.05% IT in 5% of lipid phase (Glyceryl monostearate- GMS and tween 80 (2.5 % w/v was used as surfactant in the aqueous phase. IT-SLN was characterized by particle size analyzing, differential scanning calorimetry and transmission electron microscopy. Encapsulation efficacy was also obtained using spectrophotometry. The efficacy of IT-SLN was evaluated in a randomized, single-blind, parallel-group study and compared with Isotrex®. Forty patients encountered in the study and divided in two groups. Treatment regimen was once-nightly topical administration accompanied with topical administration of clindamycin 2% solution twice a day for 8 weeks. The particle size of IT-SLN was around 60 nm with PDI of 0.4 and zeta potential was about -40 mV. Encapsulation efficacy of IT in SLN in crystalline form was 84±0.21%. IT-SLN produced significantly better treatment than Isotrex® in both non-inflammatory and inflammatory lesions according to its recovery percent after 8 weeks. Also IT-SLN gained better global assessment scores. Our results showed that IT-SLN had higher efficacy than Isotrex® to clear non-inflammatory and inflammatory lesions.

    To confirm the efficacy of the treatment regimen with oral levofloxacin (LVFX) 500 mg once daily for 7 days for patients with non-gonococcal urethritis (NGU), we evaluated the microbiological and clinical outcomes of the regimen in those patients. We finally evaluated 53 patients with symptomatic NGU and 5 patients with asymptomatic NGU. As a result of microbiological examinations, 19 of the symptomatic patients were diagnosed as having non-gonococcal chlamydial urethritis (NGCU); 13 had non-gonococcal non-chlamydial urethritis (NGNCU), and 21 had urethritis without any microbial detection. Five of the asymptomatic patients were diagnosed as having NGCU. Microbiological cure was achieved in 91% of the 32 patients with symptomatic NGU and in 80% of the 5 patients with asymptomatic NGCU. Clinical cure was obtained in 92% of the 53 patients with symptomatic NGU. The microbiological eradication rate for Chlamydia trachomatis was 92% in 24 patients. As for other organisms, the microbiological eradication rate for Mycoplasma genitalium was 60% in 5 patients and that for Ureaplasma urealyticum was 100% in 10. The microbiological and clinical efficacy of oral LVFX 500 mg once daily for 7 days for the patients with NGU was the same for the azithromycin (AZM) 1,000 mg single dose that we previously reported. The eradication rates of C. trachomatis and U. urealyticum in the treatment regimen with LVFX 500 mg were high enough in the clinical setting; however, for M. genitalium, the rate was relatively inferior to that with AZM.

    To investigate the clinical efficacy and safety of preferred use of high-frequency oscillatory ventilation (HFOV) in the treatment of neonatal pulmonary hemorrhage. The clinical efficacy of preferred use of HFOV (preferred use group) and rescue use of HFOV after conventional mechanical ventilation proved ineffective (rescue use group) in the treatment of 26 cases of neonatal pulmonary hemorrhage was retrospectively analyzed. The oxygenation index (OI), pulmonary hemorrhage time, hospitalization time, ventilation time, oxygen therapy time, complications, and outcome of the two groups were compared. Compared with the rescue use group, the preferred use group had significantly lower IO values at 1, 6, 12, 24, 48, and 72 hours after treatment (Phemorrhage, and digestive tract hemorrhage between the two groups (P>0.05). Compared with those in the rescue use group, children who survived in the preferred use group had significantly shorter pulmonary hemorrhage time, hospitalization time, ventilation time, and oxygen therapy time (P<0.05). Compared with the rescue use of HFOV, preferred use of HFOV can better improve oxygenation function, reduce the incidence of VAP, shorten the course of disease, and increase cure rate while not increasing the incidence of adverse effects.

    Full Text Available Regulatory T lymphocytes (Treg infiltrate human glioblastoma (GBM; are involved in tumor progression and correlate with tumor grade. Transient elimination of Tregs using CD25 depleting antibodies (PC61 has been found to mediate GBM regression in preclinical models of brain tumors. Clinical trials that combine Treg depletion with tumor vaccination are underway to determine whether transient Treg depletion can enhance anti-tumor immune responses and improve long term survival in cancer patients.Using a syngeneic intracrabial glioblastoma (GBM mouse model we show that systemic depletion of Tregs 15 days after tumor implantation using PC61 resulted in a decrease in Tregs present in tumors, draining lymph nodes and spleen and improved long-term survival (50% of mice survived >150 days. No improvement in survival was observed when Tregs were depleted 24 days after tumor implantation, suggesting that tumor burden is an important factor for determining efficacy of Treg depletion in clinical trials. In a T cell dependent model of brain tumor regression elicited by intratumoral delivery of adenoviral vectors (Ad expressing Fms-like Tyrosine Kinase 3 ligand (Flt3L and Herpes Simplex Type 1-Thymidine Kinase (TK with ganciclovir (GCV, we demonstrate that administration of PC61 24 days after tumor implantation (7 days after treatment inhibited T cell dependent tumor regression and long term survival. Further, depletion with PC61 completely inhibited clonal expansion of tumor antigen-specific T lymphocytes in response to the treatment.Our data demonstrate for the first time, that although Treg depletion inhibits the progression/eliminates GBM tumors, its efficacy is dependent on tumor burden. We conclude that this approach will be useful in a setting of minimal residual disease. Further, we also demonstrate that Treg depletion, using PC61 in combination with immunotherapy, inhibits clonal expansion of tumor antigen-specific T cells, suggesting that new, more

    Francisella tularensis is a highly infectious Gram-negative bacterium that is the etiologic agent of tularemia in animals and humans and a Tier 1 select agent. The natural incidence of pneumonic tularemia worldwide is very low; therefore, it is not feasible to conduct clinical efficacy testing of tularemia medical countermeasures (MCM) in human populations. Development and licensure of tularemia therapeutics and vaccines need to occur under the Food and Drug Administration's (FDA's) Animal Rule under which efficacy studies are conducted in well-characterized animal models that reflect the pathophysiology of human disease. The Tularemia Animal Model Qualification (AMQ) Working Group is seeking qualification of the cynomolgus macaque (Macaca fascicularis) model of pneumonic tularemia under Drug Development Tools Qualification Programs with the FDA based upon the results of studies described in this manuscript. Analysis of data on survival, average time to death, average time to fever onset, average interval between fever and death, and bacteremia; together with summaries of clinical signs, necropsy findings, and histopathology from the animals exposed to aerosolized F. tularensis Schu S4 in five natural history studies and one antibiotic efficacy study form the basis for the proposed cynomolgus macaque model. Results support the conclusion that signs of pneumonic tularemia in cynomolgus macaques exposed to 300–3,000 colony forming units (cfu) aerosolized F. tularensis Schu S4, under the conditions described herein, and human pneumonic tularemia cases are highly similar. Animal age, weight, and sex of animals challenged with 300–3,000 cfu Schu S4 did not impact fever onset in studies described herein. This study summarizes critical parameters and endpoints of a well-characterized cynomolgus macaque model of pneumonic tularemia and demonstrates this model is appropriate for qualification, and for testing efficacy of tularemia therapeutics under Animal Rule.

    This study examined the differential efficacy and relative costs of two intensities of adjunctive psychosocial services--a day treatment program and enhanced standard care--for the treatment of opioid-dependent patients maintained on methadone hydrochloride. A 12-week randomized clinical trial with 6-month follow-up was conducted in a community-based methadone maintenance program. Of the 308 patients who met inclusion criteria, 291 began treatment (day treatment program: N=145; enhanced standard care: N=146), and 237 completed treatment (82% of those assigned to the day treatment program and 81% of those receiving enhanced standard care). Two hundred twenty of the patients participated in the 6-month follow-up (75% of those in the day treatment program and 73% of those in enhanced standard care provided a follow-up urine sample for screening). Both interventions were 12 weeks in duration, manual-guided, and provided by master's-level clinicians. The day treatment was an intensive, 25-hour-per-week program. The enhanced standard care was standard methadone maintenance plus a weekly skills training group and referral to on- and off-site services. Outcome measures included twice weekly urine toxicology screens, severity of addiction-related problems, prevalence of HIV risk behaviors, and program costs. Although the cost of the day treatment program was significantly higher, there was no significant difference in the two groups' use of either opiates or cocaine. Over the course of treatment, drug use, drug-related problems, and HIV risk behaviors decreased significantly for patients assigned to both treatment intensities. Improvements were maintained at follow-up. Providing an intensive day treatment program to unemployed, inner-city methadone patients was not cost-effective relative to a program of enhanced methadone maintenance services, which produced comparable outcomes at less than half the cost.

    We compare the clinical efficacy of the new bougie-internal urethrectomy (BIU) with internal urethrotomy and urethroplasty to treat urethral stricture disease. We prospectively studied 186 people with urethral stricture disease. Of these, 84 were identified for urethroplasty and 102 for internal urethrotomy (endoscopic urethrotomy). Among the 84 identified for urethroplasty, 52 received BIU (Group 1) and the remaining 32 received urethroplasty. Among the 102 identified for internal urethrotomy, 58 received BIU (Group 2) and the remaining 44 received the internal urethrotomy. After surgery, we evaluated the clinical efficacy of the BIU (operative invasions, voiding flow rates, complications, sequelae) compared with the endoscopic treatment and urethroplasty. Patient age ranged from 20 to 70 years. The follow-up period was 2 years. In the BIU Group 1, the BIU Group 2, and the internal urethrotomy (endoscopic treatment), the length of strictures were 2.9 ± 1.5, 2.8 ± 1.3, 1.6 ± 0.7, and 1.5 ± 0.6, respectively. In the BIU Group 1, the urethroplasty, the BIU Group 2, and the internal urethrotomy (endoscopic treatment), the amount of bleeding was 34.1 ± 17.1, 172.2 ± 29.8, 28.5 ± 9.8, and 49.7 ± 13.6 mL, respectively. In the BIU Group 1, the urethroplasty, the BIU Group 2, and the internal urethrotomy, the recurrence rates were 5.8%, 86%, 6.8% and 25%, and the average flow rates were 18.1 ± 4.8, 13.1 ± 3.9, 18.2 ± 3.6, 10.1 ± 3.1 mL/s, respectively. There was no sequealae (sexual dysfunction, penile change) in both BIU groups. The new BIU could be considered first-line treatment in all patients with indications for visual internal urethrotomy and urethroplasty.

    Perioperative thirst is an intense discomfort with high incidence in the immediate postoperative period, but nonetheless, it is highly neglected in clinical practice. The purpose of this study was to evaluate the efficacy of an ice popsicle compared with water at room temperature for thirst relief in the immediate postoperative period in terms of variation in the intensity of the initial compared with the final thirst and the satiety reached after an hour of evaluation and intervention. A parallel randomized clinical trial was used. A total of 208 patients in the immediate postoperative period were assessed for 1 hour, every 15 minutes. Thirst intensity was assessed initially and subsequently; interventions were performed according to the group: (1) control group, 10 mL of water at room temperature; and (2) experimental group, 10-mL ice popsicle. The ice popsicle was 37.8% (P popsicle has greater efficacy than water at room temperature for thirst management in the immediate postoperative period.

    To evaluate the clinical safety and radiological feasibility of a domestic iopamidol-based contrast media (Pamiray 370) during an aortic and extremity CT angiography. Between August and December of 2008, 100 patients (M:F=51:49; mean age, 59 years) underwent an aortic and extremity CT angiography using Pamiray 370 based with informed consent. All changes in vital signs, clinical symptoms, and adverse reactions to the contrast media were monitored. Two radiologists assessed the image quality of the CT angiography. A statistical comparison was conducted using an independent t-test and a Mann-Whitney test based on the 100-patient group studied using Optiray 350. The contrast enhancement of the descending aorta in the arterial phase showed a statistically greater efficacy (p<0.001) of Pamiray 370 compared to Optiray 350, which was the routine contrast media for CT angiography for our institute. Adverse reaction signs were evident in 3%(3/100) of the subjects. All of them showed mild and transient reactions such as vomiting (n=2) and coughing (n=1), with no medical treatment required. Contrast media related symptoms including dizziness (n=7), nausea (n=3), headaches (n=2), and injection site pain (n=1), were noted in 12%(12/100). The clinical efficacy of Pamiray 370 was acceptable for the aortic and extremity CT angiography, in terms of clinical safety, tolerance, and image quality

  19. Sensitivity Analysis of Per-Protocol Time-to-Event Treatment Efficacy in Randomized Clinical Trials

    Summary Assessing per-protocol treatment effcacy on a time-to-event endpoint is a common objective of randomized clinical trials. The typical analysis uses the same method employed for the intention-to-treat analysis (e.g., standard survival analysis) applied to the subgroup meeting protocol adherence criteria. However, due to potential post-randomization selection bias, this analysis may mislead about treatment efficacy. Moreover, while there is extensive literature on methods for assessing causal treatment effects in compliers, these methods do not apply to a common class of trials where a) the primary objective compares survival curves, b) it is inconceivable to assign participants to be adherent and event-free before adherence is measured, and c) the exclusion restriction assumption fails to hold. HIV vaccine efficacy trials including the recent RV144 trial exemplify this class, because many primary endpoints (e.g., HIV infections) occur before adherence is measured, and nonadherent subjects who receive some of the planned immunizations may be partially protected. Therefore, we develop methods for assessing per-protocol treatment efficacy for this problem class, considering three causal estimands of interest. Because these estimands are not identifiable from the observable data, we develop nonparametric bounds and semiparametric sensitivity analysis methods that yield estimated ignorance and uncertainty intervals. The methods are applied to RV144. PMID:24187408

    2006-12-01

    When using botulinum toxin-based products, the physician must decide the optimal location and dose required to alleviate symptoms and improve the patient's quality of life. To deliver effective treatment, the physician needs to understand the importance of accurate target muscle selection and localization and the implications of each product's migration properties when diluted in different volumes. Pre-clinical mouse models of efficacy and safety have been utilized to compare local and distal muscle relaxation effects following defined intramuscular administration. Data from the model allow the products to be ranked based on their propensity for local efficacy versus their distal migration properties. Using standardized dilutions, the non-parallel dose-response curves for the various formulations demonstrate that they have different efficacy profiles. Distal effects were also noted at different treatment doses, which are reflected in the different safety and/or therapeutic margins. Based on these pre-clinical data, the safety and therapeutic margin rankings are ordered, largest to smallest, as BOTOX, Dysport and Myobloc. The results of subsequent clinical trials are variable and dose comparisons are inconclusive, thus supporting the regulatory position that the dose units of the individual preparations are unique and cannot be simply converted between products.

    Supervision of students is a key role of senior physiotherapy clinicians in teaching hospitals. The objective of this study was to test the effect of simulated learning environments (SLE) on educators' self-efficacy in student supervision skills. A pilot prospective randomized controlled trial with concealed allocation was conducted. Clinical educators were randomized to intervention (SLE) or control groups. SLE participants completed two 3-hour workshops, which included simulated clinical teaching scenarios, and facilitated debrief. Standard Education (StEd) participants completed two online learning modules. Change in educator clinical supervision self-efficacy (SE) and student perceptions of supervisor skill were calculated. Between-group comparisons of SE change scores were analyzed with independent t-tests to account for potential baseline differences in education experience. Eighteen educators (n = 18) were recruited (SLE [n = 10], StEd [n = 8]). Significant improvements in SE change scores were seen in SLE participants compared to control participants in three domains of self-efficacy: (1) talking to students about supervision and learning styles (p = 0.01); (2) adapting teaching styles for students' individual needs (p = 0.02); and (3) identifying strategies for future practice while supervising students (p = 0.02). This is the first study investigating SLE for teaching skills of clinical education. SLE improved educators' self-efficacy in three domains of clinical education. Sample size limited the interpretation of student ratings of educator supervision skills. Future studies using SLE would benefit from future large multicenter trials evaluating its effect on educators' teaching skills, student learning outcomes, and subsequent effects on patient care and health outcomes.

    Full Text Available A new, more palatable formulation of 10% enrofloxacin enteric-coated granules was investigated to evaluate the pharmacokinetic effect in plasma, the residue elimination in tissues and the clinical efficacy against Actinobacillus pleuropneumonia (APP and Mycoplasam suis (MS in pigs. In this study, the enrofloxacin concentrations in plasma and tissues were detected using high-performance liquid chromatography with phosphate buffer (pH = 3 and acetonitrile. The pharmacokinetics and elimination of enrofloxacin enteric-coated granules were performed after oral administration at a single dose of 10 mg/kg body weight (bw and 5 mg/kg twice per day for 5 consecutive days, respectively. The in vivo antibacterial efficacy and clinical effectiveness of enrofloxacin enteric-coated granules against APP and MS were assayed at 2.5, 5, 10 mg/kg, compared with tiamulin (8 mg/kg based on establishment of APP and MS infection models. 56 APP strains were selected and tested for in vitro antibacterial activity of enrofloxacin enteric-coated granules. The main parameters of elimination half-life (t1/2β, Tmax, and area under the curve (AUC were 14.99 ± 4.19, 3.99 ± 0.10, and 38.93 ± 1.52 μg h/ml, respectively, revealing that the enrofloxacin concentration remained high and with a sustainable distribution in plasma. Moreover, the analysis on the evaluation of enrofloxacin and ciprofloxacin in muscle, fat, liver and kidney showed that the recovery were more than 84% recovery in accordance with the veterinary drug residue guidelines of United States pharmacopeia, and the withdrawal periods were 4.28, 3.81, 4.84, and 3.51 days, respectively, suggesting that the withdrawal period was 5 d after oral administration of 5 mg/kg twice per day. The optimal dosage of enrofloxacin enteric-coated granules against APP and MS was 5 mg/kg, with over 90% efficacy, which was significantly different (p < 0.05 to the 2.5 mg/kg group, but not to the 10 mg/kg group or the positive

    In 1977 the American Psychiatric Association called for a critical examination of the clinical effectiveness of meditation. The author provides a review of the literature bearing on clinical and physiological comparisons of meditation with other self-control strategies. He begins by providing a definition of mediation and then cites the literature comparing mediation with such self-regulation strategies as biofeedback, hypnosis, and progressive relaxation. He pays particular attention to the "uniqueness" of mediation as a clinical intervention strategy a well as the adverse effects of meditation. Finally, he offers suggestions and guidelines for future research.

    Full Text Available The mainstays of cutaneous leishmaniasis (CL treatment, in several world regions, are pentavalent antimony (Sbv compounds administered parenterally, despite their recognized toxicity, which requires frequent laboratory monitoring and complicates their use in areas with scarce infrastructure. As result of these drawbacks, the WHO Expert Committee on leishmaniasis has expanded the recommendations for the use of local therapies, including Sbv intralesional infiltration (IL-Sbv, as CL therapy alternatives even in the New World. However, the efficacy of these approaches has never been compiled. The aim of this study was to critically and systematically assess the efficacy of IL-Sbv for CL treatment.The PRISMA guidelines for systematic reviews and the Cochrane manual were followed. The sources used were the MEDLINE and LILACS databases and the International Clinical Trials Registry Platform of the World Health Organization. The outcome of interest was a clinical cure, defined as complete re-epithelialization of all lesions. The IL-Sbv pooled cure rate was estimated for several subgroups and direct comparisons were performed when possible.Thirty nine articles (40 studies involving 5679 patients treated with IL-Sbv infiltration were included. In direct comparison, only three studies involving 229 patients compared IL-Sbv infiltration versus placebo and no difference was observed (OR: 1,9; 95%IC 0,93 to 3,82 based on cure rate 69.6% (95%CI 17.6-96.1% and 83,2% (95%CI 66-92.7% for placebo and IL-Sbv, respectively. In an alternative and non-comparative analysis, gathering all study arms using the intervention, the pooled IL-Sbv efficacy rate was 75% (95%CI 68-81%. In the Old World, the observed overall IL-Sbv efficacy rate was 75% (95%CI 66-82%, and the cure rates were significantly higher with sodium stibogluconate (SSG than with meglumine antimoniate (MA: 83% (95%CI 75-90% versus 68% (95%CI 54-79%, p = 0.03.

    Comparisons of the efficacy of different regimens of medical abortion are difficult because of the widely varying protocols (even for testing identical regimens), divergent definitions of success and failure, and lack of a standard method of analysis. In this article we review the current efficacy literature on medical abortion, highlighting some of the most important differences in the way that efficacy has been analyzed. We then propose a standard conceptual approach and the accompanying statistical methods for analyzing clinical trials of medical abortion and to explain how clinical investigators can implement this approach. Our review reveals that research on the efficacy of medical abortion has closely followed the conceptual model used for analysis of surgical abortion. The problem, however, is that, whereas surgical abortion is a discrete event occurring in the space of a few minutes or less, medical abortion is a process typically lasting from several days to several weeks. In this process, two events may occur that are not possible with surgical abortion. First, the woman can opt out of the process before a fair determination of efficacy can be made. Second, the process of medical abortion allows time for surgical interventions that may be convenient for the clinician but not strictly necessary from a medical perspective. Another difference from surgical abortions is that, for medical abortions, different medical abortion protocols specify different waiting periods, giving the drugs less time to work in some studies than in others before a determination of efficacy is made. We argue that, when analyzing efficacy of medical abortion, researchers should abandon their close reliance on the analogy to surgical abortion. In fact, medical abortion is more appropriately analyzed by life table procedures developed for the study of another fertility regulation technology; contraception. As with medical abortion, a woman initiating use of a contraceptive method can

    Although turmeric and its curcumin-enriched extracts have been used for treating arthritis, no systematic review and meta-analysis of randomized clinical trials (RCTs) have been conducted to evaluate the strength of the research. We systemically evaluated all RCTs of turmeric extracts and curcumin for treating arthritis symptoms to elucidate the efficacy of curcuma for alleviating the symptoms of arthritis. Literature searches were conducted using 12 electronic databases, including PubMed, Embase, Cochrane Library, Korean databases, Chinese medical databases, and Indian scientific database. Search terms used were "turmeric," "curcuma," "curcumin," "arthritis," and "osteoarthritis." A pain visual analogue score (PVAS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were used for the major outcomes of arthritis. Initial searches yielded 29 articles, of which 8 met specific selection criteria. Three among the included RCTs reported reduction of PVAS (mean difference: -2.04 [-2.85, -1.24]) with turmeric/curcumin in comparison with placebo (P curcumin treatment (mean difference: -15.36 [-26.9, -3.77]; P = .009). Furthermore, there was no significant mean difference in PVAS between turmeric/curcumin and pain medicine in meta-analysis of five studies. Eight RCTs included in the review exhibited low to moderate risk of bias. There was no publication bias in the meta-analysis. In conclusion, these RCTs provide scientific evidence that supports the efficacy of turmeric extract (about 1000 mg/day of curcumin) in the treatment of arthritis. However, the total number of RCTs included in the analysis, the total sample size, and the methodological quality of the primary studies were not sufficient to draw definitive conclusions. Thus, more rigorous and larger studies are needed to confirm the therapeutic efficacy of turmeric for arthritis.

  15. Platelet-Rich Plasma in Bone Regeneration: Engineering the Delivery for Improved Clinical Efficacy

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Human bone is a tissue with a fairly remarkable inherent capacity for regeneration; however, this regenerative capacity has its limitations, and defects larger than a critical size lack the ability to spontaneously heal. As such, the development and clinical translation of effective bone regeneration modalities are paramount. One regenerative medicine approach that is beginning to gain momentum in the clinical setting is the use of platelet-rich plasma (PRP. PRP therapy is essentially a method for concentrating platelets and their intrinsic growth factors to stimulate and accelerate a healing response. While PRP has shown some efficacy in both in vitro and in vivo scenarios, to date its use and delivery have not been optimized for bone regeneration. Issues remain with the effective delivery of the platelet-derived growth factors to a localized site of injury, the activation and temporal release of the growth factors, and the rate of growth factor clearance. This review will briefly describe the physiological principles behind PRP use and then discuss how engineering its method of delivery may ultimately impact its ability to successfully translate to widespread clinical use.

    Full Text Available Ferric carboxymaltose (FCM is an intravenous iron formulation to correct iron deficiency. Although its use has been extensively studied in clinical trials, real-world evidence regarding FCM treatment is scarce. Our aim was to evaluate the efficacy and tolerability of FCM treatment in patients with iron deficiency, with or without anemia, at a hospital outpatient clinic. Data was collected retrospectively from medical records. During this 2-year study, 459 patients were included. Mean age was 58.6 ± 17.5 years and most patients received cumulative FCM doses of 501–1000 mg (63.2%. Six weeks after administration of FCM, efficacy endpoints hemoglobin increase ≥2 g/dL, hemoglobin increase ≥3 g/dL, and transferrin saturation > 20% were attained by 41%, 20%, and 63% of patients, respectively. Patients who received higher FCM doses showed significant reduced odds of not achieving hemoglobin increase ≥2 g/dL (501–1000 mg, adjusted odds ratio [OR]: 0.34, 95% confidence interval [CI] 0.18–0.62; 1001–3000 mg, OR: 0.19, 95% CI 0.07–0.49, compared to 500 mg doses. Treatment-emergent adverse events were documented in <4% of patients. In conclusion, FCM treatment was effective and well-tolerated by outpatients with iron deficiency at a hospital clinic, and its dosage should be adjusted to improve iron deficiency management in clinical practice.

    Immune-mediated inflammatory diseases encompass a variety of different clinical syndromes, manifesting as either common diseases such as rheumatoid arthritis (RA), inflammatory bowel disease (IBD) and psoriasis, or rare diseases such as cryopyrin-associated periodic syndromes. The therapy for these diseases often involves the use of a wide range of drugs including nonsteroidal anti-inflammatory drugs (NSAIDs), glucocorticoids, immunomodulators, and biologic therapies. Due to the abundance of relevant clinical data, this article provides a general overview on the clinical impact of the concomitant use of immunomodulators and biologic therapies, with a focus on anti-tumor necrosis factor-α agents (anti-TNFα), for the treatment of RA and Crohn's disease (CD). Compared to biologic monotherapy, concomitant use of immunomodulators (methotrexate, azathioprine, and 6-mercaptopurine) often increases the systemic exposure of the anti-TNFα agent and decreases the formation of antibodies to the anti-TNFα agent, consequently enhancing clinical efficacy. Nevertheless, long-term combination therapy with immunomodulators and anti-TNFα agents may be associated with increased risks of serious infections and malignancies. Therefore, the determination whether combination therapy is suitable for a patient should always be based on an individualized benefit-risk evaluation. More research should be undertaken to identify and validate prognostic markers for predicting patients who would benefit the most and those who are at greater risk from combination therapy with immunomodulators and anti-TNFα agents. © 2015, The American College of Clinical Pharmacology.

Randomized double-blind clinical trials have shown that fingolimod significantly reduces relapse rate and ameliorates a number of brain MRI measures, including cerebral atrophy, compared to both placebo and intramuscular interferon-1a. The effect on disability progression remains controversial, since one Phase III trial showed a significant benefit of treatment while two others did not. Although fingolimod has a very convenient daily oral dosing, the possibility of serious cardiac, ocular, infectious, and other rare adverse events justified the decision of the European Medicines Agency to approve the drug as a second-line treatment for MS patients not responsive to first-line therapy, or those with rapidly evolving course. In the United States, fingolimod is instead authorized as a first-line treatment. The aim of this review is to describe and discuss the characteristics of fingolimod concerning its efficacy, safety, and tolerability in the clinical context of multiple sclerosis management.

    Science learning self-efficacy could be regarded as a multi-factor belief which comprises different aspects such as cognitive skills, practical work, and everyday application. However, few studies have investigated the relationships among these factors that compose science learning self-efficacy. Also, culture may play an important role in explaining the relationships among these factors. Accordingly, this study aimed to investigate cultural differences in science learning self-efficacy and examine the relationships within factors constituting science learning self-efficacy by adopting a survey instrument for administration to students in the U.S. and Taiwan. A total of 218 university students (62.40% females) were surveyed in the U.S.A, and 224 university students (49.10% females) in Taiwan were also invited to take part in the study. The results of the structural equation modelling revealed cultural differences in the relationships among the factors of science learning self-efficacy. It was found that U.S. students' confidence in their ability to employ higher-order cognitive skills tended to promote their confidence in their ability to accomplish practical work, strengthening their academic self-efficacy. However, the aforementioned mediation was not found for the Taiwanese participants.

    Daratumumab (a human CD38-directed monoclonal antibody) and pomalidomide (an immunomodulatory drug) plus dexamethasone are both relatively new treatment options for patients with heavily pretreated multiple myeloma. A matching adjusted indirect comparison (MAIC) was used to compare absolute treatment effects of daratumumab versus pomalidomide + low-dose dexamethasone (LoDex; 40 mg) on overall survival (OS), while adjusting for differences between the trial populations. The MAIC method reduces the risk of bias associated with naïve indirect comparisons. Data from 148 patients receiving daratumumab (16 mg/kg), pooled from the GEN501 and SIRIUS studies, were compared separately with data from patients receiving pomalidomide + LoDex in the MM-003 and STRATUS studies. The MAIC-adjusted hazard ratio (HR) for OS of daratumumab versus pomalidomide + LoDex was 0.56 (95% confidence interval [CI], 0.38-0.83; p  = .0041) for MM-003 and 0.51 (95% CI, 0.37-0.69; p  < .0001) for STRATUS. The treatment benefit was even more pronounced when the daratumumab population was restricted to pomalidomide-naïve patients (MM-003: HR, 0.33; 95% CI, 0.17-0.66; p  = .0017; STRATUS: HR, 0.41; 95% CI, 0.21-0.79; p  = .0082). An additional analysis indicated a consistent trend of the OS benefit across subgroups based on M-protein level reduction (≥50%, ≥25%, and <25%). The MAIC results suggest that daratumumab improves OS compared with pomalidomide + LoDex in patients with heavily pretreated multiple myeloma. This matching adjusted indirect comparison of clinical trial data from four studies analyzes the survival outcomes of patients with heavily pretreated, relapsed/refractory multiple myeloma who received either daratumumab monotherapy or pomalidomide plus low-dose dexamethasone. Using this method, daratumumab conferred a significant overall survival benefit compared with pomalidomide plus low-dose dexamethasone. In the absence of head-to-head trials, these

    Full Text Available Désirée Larenas-Linnemann Pediatric Allergy and Asthma Clinic, Department of Investigation, Hospital Médica Sur, México City, México Abstract: Due to differences between allergen immunotherapy (AIT trials in patient populations, trial design (including primary efficacy variables, the definition of a pollen season, data analysis, and comparisons between AIT products with existing data, is not possible nor valid. The efficacy of two grass pollen AIT tablets, Oralair® and Grazax®/Grastek®, should not be compared by looking at the percentage of score improvement in their respective trials. However, the evidence available concerning the efficacy and safety in trials can be compared by paying close attention to the scientific quality of the trials, details in the administration schedules, and safety issues. It can be concluded due to the high level of evidence available, that Oralair® is effective in a pre (2-months-coseasonal schedule to reduce symptoms and medication use, and improve a patients’ quality of life during the treatment season. For the long-term, where the quality of efficacy evidence is moderate at 2-year posttreatment due to a high dropout rate, the pre (4-months-coseasonal schedule should be used. No clinical efficacy data exists for starting treatment in-season, but the clinical onset of action of Oralair® is detectable after only 1 month of treatment. In the pivotal trials in Europe and the USA, no tablet-related epinephrine was needed, though some rare severe local reactions have been reported. Research for Grazax®/Grastek® showed that the long-term efficacy needs a continuous 3-year administration (moderate-low quality evidence available, and in two patients, tablet-related epinephrine was given. Further details on the comparative efficacy of both tablets would only be possible if both were evaluated in the same, adequately powered trial.

    To assess the diagnostic efficacy and therapeutic impact of CT in evaluating patients with clinically suspected otosclerosis. CT scans performed over a 5-year period for clinically suspected otosclerosis were retrospectively reviewed. CT diagnoses were correlated with subsequent surgical management. For otosclerosis positive cases, clinically significant extensions of otosclerosis were correlated with audiometry and the diagnosis was correlated with surgical findings. Of 259 CT studies, 46 % of patients were positive, 49 % negative and 5 % equivocal for otosclerosis. A relevant alternative CT diagnosis was evident in 33 % of the negative studies. One targeted surgery was performed for every four CT studies. CT outcome influenced the decision to perform stapedectomy in 41 % CT-positive versus 4 % CT-negative patients. CT-positive ears for otosclerosis could not be predicted from baseline clinical or audiometric criteria. Those with endosteal extension demonstrated lower bone conduction thresholds presurgically. The positive predictive value of CT diagnosis of otosclerosis was 100 %. CT demonstrated a high rate of clinically relevant diagnoses in both CT-positive and -negative for otosclerosis patients, and this frequently influenced surgical management. CT also added value by demonstrating relevant extensions of the otosclerotic foci, some of which were predictive of audiometric parameters. (orig.)

    The aim of this short-term open parallel longitudinal clinical study was to compare the clinical and microbiological efficacy of 2 different antibiotic regimes in the treatment of acute periodontal abscesses. After patient selection, a clinical examination was carried out recording the following variables: pain, edema, redness, swelling, bleeding on probing, suppuration, tooth mobility, lymphadenopathy, and probing pocket depth. Microbiological samples were taken from the lesion and the patient was randomly assigned to one of two antibiotic regimes: azithromycin or amoxicillin/clavulanate. Clinical variables were recorded, and microbiological samples were taken, at 3-5 days, 10-12 days and 30 days. Additional mechanical treatment (debridement and scaling) was performed in the third visit (10-12 days). Blood and urine samples were collected at baseline and after 10-12 days. Microbiological samples were processed by anaerobic culturing, and isolated periodontal pathogens were tested for antibiotic susceptibility by means of the spiral gradient endpoint methodology. 15 patients took azithromycin, and 14 amoxicillin/clavulanate. Subjective clinical variables demonstrated statistically significant improvements with both antibiotic regimes, which lasted for at least 1 month (pperiodontal abscesses in periodontitis patients.

    Full Text Available Introduction: Brain arteriovenous malformations (BAVMs are associated with high morbidity and mortality. The treatment of BAVM remains controversial. Microinvasive treatment, including endovascular therapy and gamma knife surgery, has been the first choice in many conditions. However, the overall clinical outcome of microinvasive treatment remains unknown and a prospective trial is needed. Methods: This is a prospective, non-randomized, and multicenter observational registry clinical trial to evaluate the safety and efficacy of microinvasive treatment for BAVMs. The study will require up to 400 patients in approximately 12 or more centers in China, followed for 2 years. Main subjects of this study are BAVM patients underwent endovascular therapy and/or gamma knife surgery. The trial will not affect the choice of treatment modality. The primary outcomes are perioperative complications (safety, and postoperative hemorrhage incidence rate and complete occlusion rate (efficacy. Secondary outcomes are elimination of hemorrhage risk factors (coexisting aneurysms and arteriovenous fistula, volume reduction and remission of symptoms. Safety and efficacy of endovascular therapy, gamma knife surgery, and various combination modes of the two modalities will be compared. Operative complications and outcomes at pretreatment, post-treatment, at discharge and at 3 months, 6 months and 2 years follow-up intervals will be analyzed using the modified Rankin Scale (mRS. Discussion: The most confusion on BAVM treatment is whether to choose interventional therapy or medical therapy, and the choice of interventional therapy modes. This study will provide evidence for evaluating the safety and efficacy of microinvasive treatment in China, to characterize the microinvasive treatment strategy for BAVMs. Keywords: Brain arteriovenous malformation, Clinical trial, Endovascular therapy, Gamma knife, Safety, Efficacy

    Vulvovaginal candidiasis (VVC) and recurrent VVC (RVVC) remain major health problems for women. VT-1161, a novel fungal CYP51 inhibitor which has potent antifungal activity against fluconazole-sensitive Candida albicans, retained its in vitro potency (MIC50 of ≤0.015 and MIC90 of 0.12 μg/ml) against 10 clinical isolates from VVC or RVVC patients resistant to fluconazole (MIC50 of 8 and MIC90 of 64 μg/ml). VT-1161 pharmacokinetics in mice displayed a high volume of distribution (1.4 liters/kg), high oral absorption (73%), and a long half-life (>48 h) and showed rapid penetration into vaginal tissue. In a murine model of vaginal candidiasis using fluconazole-sensitive yeast, oral doses as low as 4 mg/kg VT-1161 significantly reduced the fungal burden 1 and 4 days posttreatment (P < 0.0001). Similar VT-1161 efficacy was measured when an isolate highly resistant to fluconazole (MIC of 64 μg/ml) but fully sensitive in vitro to VT-1161 was used. When an isolate partially sensitive to VT-1161 (MIC of 0.12 μg/ml) and moderately resistant to fluconazole (MIC of 8 μg/ml) was used, VT-1161 remained efficacious, whereas fluconazole was efficacious on day 1 but did not sustain efficacy 4 days posttreatment. Both agents were inactive in treating an infection with an isolate that demonstrated weaker potency (MICs of 2 and 64 μg/ml for VT-1161 and fluconazole, respectively). Finally, the plasma concentrations of free VT-1161 were predictive of efficacy when in excess of the in vitro MIC values. These data support the clinical development of VT-1161 as a potentially more efficacious treatment for VVC and RVVC. Copyright © 2015, American Society for Microbiology. All Rights Reserved.

    There is a lack of research investigating parental self-efficacy in parents of infants born preterm as well as a paucity of parental self-efficacy measures that are domain-specific and theoretically grounded. This study aimed to compare parental self-efficacy in parents of infants born term, preterm and very preterm as well as to test whether parental self-efficacy mediates the relationship between psychological symptoms and parental competence. In order to achieve this, a new measure of parental self-efficacy and parental competence relevant for the preterm population and consistent with Bandura's (1977, 1986, 1989) conceptualisation of self-efficacy was developed. Participants included 155 parents, 83 of whom were parents of very preterm (GAparents of preterm (GAparents of term born infants. Parents completed the Preterm Parenting & Self-Efficacy Checklist (the new measure), Family Demographic Questionnaire, Depression Anxiety Stress Scale and Self-Efficacy Questionnaire. This initial study indicates that the Preterm Parenting & Self-Efficacy Checklist has adequate content validity, construct validity, internal consistency and split half reliability. Contrary to expectations, parents of very preterm infants did not report significantly lower overall levels of parental self-efficacy or significantly higher levels of psychological symptoms compared to parents of preterm and term infants. Parental self-efficacy about parenting tasks mediated the relationship between psychological symptoms and self perceived parental competence as predicted. Clinical implications of the results and suggestions for future research are discussed. Crown Copyright © 2012. Published by Elsevier Inc. All rights reserved.

    Five major first- and second-generation epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs), including erlotinib, gefitinib, icotinib, afatinib, and dacomitinib, are currently optional for patients with advanced non-small-cell lung cancer (NSCLC) who harbor EGFR mutations. However, there was no head-to-head-based network meta-analysis among all the TKIs in EGFR-mutated populations. Eligible literature was searched from an electronic database. Data of objective response rate, disease control rate, progression-free survival, and overall survival were extracted from enrolled studies. Multiple treatment comparisons based on Bayesian network integrated the efficacy of all included treatments. Six phase III randomized trials involving 1055 EGFR-mutated patients with advanced NSCLC were enrolled. Multiple treatment comparisons showed that 5 different EGFR-TKIs shared equivalent therapeutic efficacy in terms of all outcome measures. Rank probabilities indicated that dacomitinib and afatinib had potentially better efficacy compared with erlotinib, gefitinib, and icotinib in the EGFR-mutated patients. When compared with other agents, potential survival benefits (progression-free and overall survival) were observed in dacomitinib, whereas afatinib showed a better rank probability in overall response rate and disease control rate. Our study indicated a preferable therapeutic efficacy in the second-generation TKIs (dacomitinib and afatinib) when compared with the first-generation TKIs (erlotinib, gefitinib, and icotinib).

    The present study examined the relationship between maternal self-efficacy, dysfunctional discipline practices and child conduct problems. Specifically, three levels of self-efficacy, global, domain and task-specific self-efficacy, were assessed in mothers of 2- to 8-year-old children with conduct problems (clinic group, n=45) and non-clinic mothers from the community (non-clinic group, n=79). Measures of global, domain and task-specific self-efficacy were completed by mothers. Clinic mothers reported significantly lower self-efficacy than non-clinic mothers for all but one of the parenting tasks assessed. Both groups of mothers reported lowest self-efficacy for similar parenting tasks. In the sample as a whole self-efficacy measures were significant predictors of maternal discipline style after controlling for other parent, child and risk factors. Of the self-efficacy variables behavioural self-efficacy was the best predictor of mothers discipline style. The findings support the importance of developing parenting strategies that enable parents to generalize their parenting skills to a diverse range of diverse parenting contexts both in the home and in the community.

    To estimate the efficacy of alginate carboxymethylcellulose hyaluronic acid (ACH) gel to prevent intrauterine adhesions after hysteroscopic surgery in comparison with carboxymethylcellulose hyaluronic acid (CH) gel, which is known as an effective adhesion inhibitor. Randomized, multicenter, single-blind, clinical trial (Canadian Task Force classification I). Tertiary university hospital. One hundred eighty-seven patients with a surgically treatable intrauterine lesion (myomas, polyps, septa, intrauterine adhesion, dysfunctional uterine bleeding). Patients were randomized to 2 groups: hysteroscopic surgery plus intrauterine application of ACH or CH. The rate of adhesion formation and the adhesion severity score with type and extent were calculated 4 weeks after surgery. The ACH group had results that were comparable to the CH group in terms of the development of intrauterine adhesions at 4 weeks follow-up. The adhesion severities were not different between the 2 groups. In a subgroup without baseline intrauterine adhesion, the ACH group showed a lower intrauterine adhesion rate than the CH group (p = .016). ACH had a comparable efficacy to CH in terms of the adhesion rate and severity. In the case of no baseline intrauterine adhesion, intrauterine application of ACH after hysteroscopic surgery had a lower rate of intrauterine adhesion than application of CH. Copyright © 2012 AAGL.

    Although transforaminal epidural steroid injections under fluoroscopic guidance have become a common mode of treatment of lumbosacral radiculopathy due to herniated disc, the efficacy of steroid with low doses of clonidine has not been compared yet. Comparison of the analgesic efficacy of methylprednisolone alone and with low doses of clonidine for transforaminal injection in lumbosacral radiculopathy. A randomized, double-blind trial. This study was performed at the Pain Clinic under the Department of Anaesthesiology, Jawaharlal Nehru Medical College Hospital, Aligarh Muslim University, Aligarh, India. One hundred and eighty ASA grade I and II patients aged between 18 and 55 years were allocated into groups I, II and III to receive methylprednisolone 60 mg alone or methylprednisolone 60 mg with or without low doses of clonidine (0.5 mcg/kg or 1 mcg/kg) as transforaminal epidural injection. Pain relief and patient's satisfaction were evaluated with the global pain scale. Follow-up visits were advised at 1, 2, 4, 6 and 12 weeks and then at 6 months after injection. Associated complications were recorded. Maximum pain relief was observed at 2 weeks after injection in all the three groups, with no difference in complication rate among the three groups. The most common complication observed was paresthesia in the nerve distribution. Greater than 60% improvement in pain scores was seen in 40% of the patients in group I, 50% of the patients in group II and 75% of the patients in group III. This study is limited by the lack of a placebo group. Adding 1 mcg/kg clonidine to 60 mg methylprednisolone in transforaminal epidural injections provided better pain relief than 60 mg methylprednisolone with 0.5 mcg/kg clonidine or 60 mg methylprednisolone alone in patients suffering from lumbosacral radiculopathy, with practically no significant side-effects.

    We have assessed the efficacy of anti retroviral therapy (ART) using undetectable viral load (VL) (<50 RNA copies\\/ml) as a marker of virological success, in patients who have Human Immunodeficiency Virus (HIV) attending the Department of Infectious Disease. A cross-sectional review of patients\\' case notes was used to obtain their demographics and treatment details. 79% (253) of the hospital case notes of clinic population was available for analysis, which represents 90% of those receiving ART in the clinic. 166\\/253 of the cohort were receiving treatment at the time of this study and 95% (157\\/166) of these were on treatment for greater than 6 months. The total virological success rate is 93%, which is comparable to other centres and are as good as those from published clinical trials. 56% of those on therapy who have virological failure were Intravenous Drug Users (IVDUs). Case by case investigation for those with treatment failure is warranted.

    To examine the protective efficacy of measles vaccination in infants in a low income country before 9 months of age. Randomised clinical trial. 1333 infants aged 4.5 months: 441 in treatment group and 892 in control group. Urban area in Guinea-Bissau. Measles vaccination using standard titre Edmonston-Zagreb vaccine at 4.5 months of age. Vaccine efficacy against measles infection, admission to hospital for measles, and measles mortality before standard vaccination at 9 months of age. 28% of the children tested at 4.5 months of age had protective levels of maternal antibodies against measles at enrolment. After early vaccination against measles 92% had measles antibodies at 9 months of age. A measles outbreak offered a unique situation for testing the efficacy of early measles vaccination. During the outbreak, 96 children developed measles; 19% of unvaccinated children had measles before 9 months of age. The monthly incidence of measles among the 441 children enrolled in the treatment arm was 0.7% and among the 892 enrolled in the control arm was 3.1%. Early vaccination with the Edmonston-Zagreb measles vaccine prevented infection; vaccine efficacy for children with serologically confirmed measles and definite clinical measles was 94% (95% confidence interval 77% to 99%), for admissions to hospital for measles was 100% (46% to 100%), and for measles mortality was 100% (-42% to 100%). The number needed to treat to prevent one case of measles between ages 4.5 months and 9 months during the epidemic was 7.2 (6.8 to 9.2). The treatment group tended to have lower overall mortality (mortality rate ratio 0.18, 0.02 to 1.36) although this was not significant. In low income countries, maternal antibody levels against measles may be low and severe outbreaks of measles can occur in infants before the recommended age of vaccination at 9 months. Outbreaks of measles may be curtailed by measles vaccination using the Edmonston-Zagreb vaccine as early as 4.5 months of age. TRIAL

    We assessed the efficacy of fosfomycin trometamol in treating uncomplicated gonococcal urethritis in men. We conducted an open randomized controlled trial in 152 consecutive men with any main complaints suggestive of uncomplicated gonococcal urethritis in Dujiangyan Medical Center between 1 September 2013 and 31 August 2015. In total, 126 patients completed all aspects of this study. Sixty were provided therapy with fosfomycin trometamol 3 g orally on days 1, 3 and 5 in the intervention group; the other 61 were provided ceftriaxone 250 mg intramuscularly plus azithromycin 1 g orally simultaneously as a single dose in the control group. The primary outcomes involved clinical and microbiologic cure on days 7 and 14 after receipt of all the study medications. At the day 7 follow-up visit, all the 121 participants had complete resolution of clinical symptoms and signs. In addition, five patients (two in the intervention group and three in the control group) discontinued intervention because of unsuccessful treatment. After receipt of all the study medications, these five patients still had urethral purulent discharge and were switched to other unknown treatment regimens by other doctors. The bacterial smears and cultures of urethral or urine specimens in the 121 patients who completed all aspects of the study were negative on a test-of-cure visit. In the per-protocol analysis, both clinical and microbiologic cure were experienced by 96.8% (60/62 patients) in the intervention group and 95.3% (61/64 patients) in the control group. There were no recurrences at the day 14 test-of-cure visit. This trial indicates that fosfomycin trometamol exhibits excellent efficacy for treatment of uncomplicated gonococcal urethritis in men. Serious adverse effects are rare. Copyright © 2016 European Society of Clinical Microbiology and Infectious Diseases. Published by Elsevier Ltd. All rights reserved.

    To evaluate the efficacy and safety profile of paracetamol in comparison with tramadol for pain relief during active labor. Prospective, randomized, double-blind study. Maternity Wing of the Postgraduate Institute of Medical Education and Research, Chandigarh. Sixty laboring, primiparous, full-term parturients with uncomplicated, singleton pregnancy in spontaneous labor and cervical dilatation of 3-5 cm. Parturients were randomized into 2 groups to receive either 1 mg/kg of tramadol intramuscularly (group T; n = 29) or 1 g of paracetamol intravenously (group P; n = 30). Same doses of the drugs were repeated after 4 hours of initial dose. Primary outcome of the study was to assess the analgesic efficacy of the 2 drugs as measured by visual analog scale (VAS) score. Secondary outcome recorded was duration of labor, presence of any maternal, or fetal adverse events during the study. Both the groups showed comparable VAS scores at all times of observation. Lower mean VAS scores were reported in both the groups till 120 minutes only. The duration of first stage of labor was shorter in group P (248.00 ± 98.171 vs 340.63 ± 111.592 minutes; P = .003). The duration of second stage of labor was comparable between the 2 groups. Higher incidence of maternal side effects such as nausea/vomiting and sedation was associated with the use of tramadol. Neonatal outcome was comparable. Intravenous paracetamol provides comparable analgesia as intramuscular tramadol during active labor. Copyright © 2014 Elsevier Inc. All rights reserved.

    To clarify the clinical efficacy of STFX for patients with non-gonococcal urethritis (NGU), including chlamydial urethritis and Mycoplasma genitalium-positive urethritis, this study included male patients with NGU who were 20 years old or older. The pathogens, including Chlamydia trachomatis, M. genitalium and Ureaplasma urealyticum, were detected by nucleic acid amplification tests and the patients were treated with sitafloxacin 100 mg twice daily for 7 days. Microbiological and clinical efficacies were assessed for the patients with NGU posttreatment. Among the 208 patients enrolled in this study, data for a total of 118 patients could be analyzed. The median age was 32 (20-61) years. The median duration from the completion of treatment to the second visit was 21 (14-42) days. There were 68 pathogen-positive NGU cases and 50 with NGU without any microbial detection. Microbiological cure was achieved in 95.6% of the pathogen-positive NGU patients. Total clinical cure was achieved in 91.3% (105/115). In this study, STFX was able to eradicate 95.7% of C. trachomatis, 93.8% of M. genitalium and 100% of U. urealyticum. The results of our clinical research indicate that the STFX treatment regimen should become a standard regimen recommended for patients with NGU. In addition, this regimen is recommended for patients with M. genitalium-positive NGU.

    Protamine sulfate (PS), the only clinically approved antidote to unfractionated heparin (UFH), is widely used for cardiopulmonary surgery or other extracorporeal circulation situations. However, the applications of PS have accompanied various severe side-effects. In this study, we presented a novel synthesized peptide compound (RRRRR-RRRRR-RRRRR-sulfate, R15S) served as a safer UFH antidote. Comparison studies were conducted between PS and R15S on efficacy and safety, aided by heparin neutralization studies, drug toxicity studies and anaphylactic analysis. Our research demonstrated that R15S contained comparable UFH neutralization activity in vitro and in rats in vivo as to active partial thromboplastin time (APTT) and anti-FXa assays. There was no cytotoxicity for R15S at 60 μg mg{sup −1} or below and the median lethal dose (LD{sub 50}) of R15S in mice was 35.4 mg kg{sup −1}, both of which were similar to that of PS. Furthermore, R15S exhibited no immunogenicity while it was obvious in guinea pigs immunized with PS. The level of cross-reactivity to anti-PS antibodies of R15S was about 30%. Both of which indicated much safer properties of R15S than PS. In conclusion, we presented a promising candidate R15S for UFH reversal, which is effective in neutralizing UFH and potentially safer in use. - Highlights: • R15 sulfate has a comparable unfractionated heparin neutralization activity to PS. • R15 sulfate avoided severe anaphylactic responses which happened to PS in clinical use. • R15 sulfate could provide a stricter quality control compared to PS which may vary with different batches.

    Objective: To compare the clinical efficacy between covered stent and uncovered stent in transjuglar in-trahepatic portosystemic shunt (TIPS). Methods: Thirty patients with liver cirrhosis (portal hypertension), who received TIPS, were retrospectively studied. All patients were divided into two groups covered-stent group (n=20) and uncovered-stent group (n=10). For each patient, portal pressure was measured before and after operation, and the patency of shunt was evaluated by color Doppler ultrasound after operation. The mortality, recurrent bleeding rate and incidence of hepatic encephalopathy were analyzed by Fisher exact probability test. Results: The TIPS treatment was successful in all patients, the portal pressure in the covered-stent group reduced from (3.78 ± 0.50)kPa to (2.13 ± 0.44) kPa and that of the uncovered-stent group reduced from (3.67 ± 0.48)kPA TO (2.13 ± 0.35)kPa. Twenty-six cases were postoperatively followed-up (17 cases in covered-stent group, 9 cases in uncovered-stent group). the follow-up period varied from 7 days to 62 months (median follow-up period was 23 months). Thirteen patients died of upper gastrointestinal bleeding and hepatic failure. The difference of mortality between covered-stent group (8/17) and uncovered-stent group (5/17) and the uncovered-stent group (3/9) was not different too (P>0.05). The incidence of hepatic encephalopathy in the covered-stent group (4/17) was not different from that of the uncovered-stent group (2/9) (P>0.05). The patency rates of 6 months and 12 months reached 100% in the covered-stent group, which were higher than those in the uncovered-stent group 77.8% (7/9) and 55.6%(5/9) (P<0.05). Conclusions: The patency rate of shunt at 12 months after TIPS was higher in the covered-stent group than the uncovered-stent group, while the mortality, recurrent bleeding rate and incidence of hepatic encephalopathy were not significantly different between the two groups.

    Although self-efficacy has been used extensively in the field of nursing (e.g., as an outcome measure of nursing interventions), its underlying nature is poorly understood. Investigation of the relationship between self-efficacy and brain activation will help explain the fundamental nature of self-efficacy. In this study, we compared prefrontal activation measured with near-infrared spectroscopy (NIRS) across 89 undergraduate students categorized into three groups based on their General Self-Efficacy Scale scores: low self-efficacy ( n = 59), moderate self-efficacy ( n = 17), and high self-efficacy ( n = 13). Changes in the hemoglobin levels of the prefrontal cortex (PFC) during a verbal fluency task were assessed using two-channel NIRS. Significant differences in the oxygenated hemoglobin (oxy-Hb) level of the left PFC (LPFC) were observed via analysis of variance. Post hoc Tukey's test showed a significant difference only between low self-efficacy and moderate self-efficacy groups. We found a medium between-group effect size in the moderate self-efficacy group versus the low self-efficacy group for the changes in oxy-Hb levels of the LPFC ( d = .78; 95% confidence interval for effect size [0.22, 1.33]). No significant between-group differences were observed with respect to changes in the oxy-Hb in the right PFC. The results indicate less left prefrontal activation in the low self-efficacy group than in the moderate self-efficacy group. These findings provide evidence to support the fundamental nature of self-efficacy.

Between July 2016 and February 2017, 36 patients who met the enrollment criteria were randomly assigned to two groups: autogeneic NK cells immunotherapy group (group I, n=18 and allogeneic NK cells immunotherapy group (group II, n=18. The clinical efficacy, quality of life, immune function, circulating tumor cell (CTC level, and other related indicators were evaluated. We found that allogeneic NK cells immunotherapy has better clinical efficacy than autogeneic therapy. Moreover, allogeneic NK cells therapy improves the quality of life, reduces the number of CTCs, reduces carcinoembryonic antigen and cancer antigen 15-3 (CA15-3 expression, and significantly enhances immune function. To our knowledge, this is the first clinical trial to compare the clinical outcome of autogeneic and allogeneic NK cells immunotherapy for recurrent breast cancer.

    Skin antisepsis is a simple and effective measure to prevent infections. The efficacy of chlorhexidine is actively discussed in the literature on skin antisepsis. However, study outcomes due to chlorhexidine-alcohol combinations are often attributed to chlorhexidine alone. Thus, we sought to review the efficacy of chlorhexidine for skin antisepsis and the extent of a possible misinterpretation of evidence. We performed a systematic literature review of clinical trials and systematic reviews investigating chlorhexidine compounds for blood culture collection, vascular catheter insertion and surgical skin preparation. We searched PubMed, CINAHL, the Cochrane Library, the Agency for Healthcare Research and Quality website, several clinical trials registries and a manufacturer website. We extracted data on study design, antiseptic composition, and the following outcomes: blood culture contamination, catheter colonisation, catheter-related bloodstream infection and surgical site infection. We conducted meta-analyses of the clinical efficacy of chlorhexidine compounds and reviewed the appropriateness of the authors' attribution. In all three application areas and for all outcomes, we found good evidence favouring chlorhexidine-alcohol over aqueous competitors, but not over competitors combined with alcohols. For blood cultures and surgery, we found no evidence supporting chlorhexidine alone. For catheters, we found evidence in support of chlorhexidine alone for preventing catheter colonisation, but not for preventing bloodstream infection. A range of 29 to 43% of articles attributed outcomes solely to chlorhexidine when the combination with alcohol was in fact used. Articles with ambiguous attribution were common (8-35%). Unsubstantiated recommendations for chlorhexidine alone instead of chlorhexidine-alcohol were identified in several practice recommendations and evidence-based guidelines. Perceived efficacy of chlorhexidine is often in fact based on evidence for the

    Full Text Available Musculoskeletal injury confers an enormous burden of preventable disability and mortality in low- and moderate-income countries (LMICs. Appropriate orthopedic and trauma care services are lacking. Leading international health agencies emphasize the critical need to create and sustain research capacity in the developing world as a strategic factor in the establishment of functional, independent health systems. One aspect of building research capacity is partnership between developing and developed countries, and knowledge sharing via these collaborations. This study evaluated the efficacy of a short, intensive course designed to educate surgeons on fundamental aspects of clinical research using evidence-based medicine (EBM principles. Orthopedic surgeons from the United States and Canada presented a one-day course on the fundamentals of clinical research in Havana, Cuba. Knowledge acquisition was assessed on the part of course participants and surveyed current involvement with and attitudes toward clinical research. Questionnaires were presented to participants immediately preceding and following the course. The mean pre-test score was 43.9% (95% CI: 41.1–46.6%. The mean post-test score was 59.3% (95% CI: 56.5–62.1%. There were relative score increases in each subgroup based on professional level, subjective level of familiarity with EBM concepts, and subjective level of experience in research. This study establishes the short-term efficacy of an intensive course designed to impart knowledge in EBM and clinical research. Further study is necessary to determine the long-term benefits of this type of course. This may be a useful part of an overall strategy to build health research capacity in LMICs, ultimately contributing to improved access to high-quality surgical care.

    Full Text Available Abstract Background Reducing low-density lipoprotein cholesterol (LDL-C is associated with reduced risk for major coronary events. Despite statin efficacy, a considerable proportion of statin-treated hypercholesterolemic patients fail to reach therapeutic LDL-C targets as defined by guidelines. This study compared the efficacy of ezetimibe added to ongoing statins with doubling the dose of ongoing statin in a population of Taiwanese patients with hypercholesterolemia. Methods This was a randomized, open-label, parallel-group comparison study of ezetimibe 10 mg added to ongoing statin compared with doubling the dose of ongoing statin. Adult Taiwanese hypercholesterolemic patients not at optimal LDL-C levels with previous statin treatment were randomized (N = 83 to ongoing statin + ezetimibe (simvastatin, atorvastatin or pravastatin + ezetimibe at doses of 20/10, 10/10 or 20/10 mg or doubling the dose of ongoing statin (simvastatin 40 mg, atorvastatin 20 mg or pravastatin 40 mg for 8 weeks. Percent change in total cholesterol, LDL-C, high-density lipoprotein cholesterol (HDL-C and triglycerides, and specified safety parameters were assessed at 4 and 8 weeks. Results At 8 weeks, patients treated with statin + ezetimibe experienced significantly greater reductions compared with doubling the statin dose in LDL-C (26.2% vs 17.9%, p = 0.0026 and total cholesterol (20.8% vs 12.2%, p = 0.0003. Percentage of patients achieving treatment goal was greater for statin + ezetimibe (58.6% vs doubling statin (41.2%, but the difference was not statistically significant (p = 0.1675. The safety and tolerability profiles were similar between treatments. Conclusion Ezetimibe added to ongoing statin therapy resulted in significantly greater lipid-lowering compared with doubling the dose of statin in Taiwanese patients with hypercholesterolemia.

    Allergy to house dust mite is one of the most common causes of allergic rhinitis. A novel tyrosine-adsorbed, modified allergen product, Acarovac Plus, developed for the treatment of perennial mite allergy seeks to address the underlying cause of allergic rhinitis in this instance. One of two dosing regimens may be used, either the Conventional Regimen or the Cluster Regimen. We sought to compare the efficacy and safety of a specific immunotherapy, developed for the treatment of perennial mite allergy, administered under a Conventional and Clustered dosing schedule in patients with persistent allergic rhinitis. Thirty adult patients, between 18 and 65 years old, with allergic rhinitis and/or asthma secondary to hypersensitivity to Dermatophagoides pteronyssinus were administered with either conventional or cluster initial regime, with a final visit one week after the last dose administration. The efficacy to the Conventional and Cluster regimens was measured using a Nasal Challenge Test monitoring clinical symptoms and peak nasal inspiratory flow. Total IgE, serum-specific inmunoglobulins (IgE and IgG4) to Dermatophagoides pteronyssinus and relevant cytokines (IFN-γ, IL-4, IL-5, IL-10 and IL-13) were assessed. A Satisfaction Questionnaire (TSQM) was completed after each patient's final visit. The tolerability of the vaccine was assessed monitoring adverse reactions. No adverse events were recorded in either conventional or cluster regime. The specific Nasal Challenge Test led to a decrease in symptom scores and a significant decrease in mean nasal peak inspiratory flow drop was recorded in both dosing regimen groups. A significant increase in IgG4-specific antibody titres was assessed. No significant changes were observed in concentrations of total IgE, specific IgE or cytokines (IFN-γ, IL-4, IL-5, IL-10 and IL-13). Patients declared themselves most satisfied in relation to “Secondary effects”, with high overall satisfaction in both groups. Cluster and

    Oral triptans have dominated the prescription market for acute treatment of migraine for nearly 25 years. Today, patients often express dissatisfaction with prescribed acute treatment in part because they do not have confidence that the therapy will provide consistent efficacy over time. Major limitations to sustained successful use of oral triptans are their relatively slow onset of meaningful clinical benefit and variable absorption/efficacy due to impaired gastrointestinal function during migraine. AVP-825, a new intranasal delivery system for sumatriptan , may be an effective alternative to oral triptans. This article reviews AVP-825, which deposits low-dose sumatriptan powder deep into the vascular mucosa of the posterior nose, allowing rapid absorption of drug into the systemic circulation. Studies suggest that AVP-825 is a highly effective, well-tolerated acute treatment for episodic migraine. Oral triptans are limited in providing effective patient-centered outcomes to migraine patients. Failed or suboptimal abortive treatment of migraine is a major driver of migraine chronification and increases in healthcare costs. AVP-825 is an easy to use, novel, breath-powered intranasal delivery system that provides early onset of efficacy with low systemic drug exposure and few triptan-associated adverse events. AVP-825 will be a welcomed therapeutic tool for the acute treatment of migraine.

    Full Text Available The objective of this review was to evaluate the clinical efficacy and safety of remifentanil in the management of labor pain. Although neuraxial analgesia is the best option during labor, alternative analgesic options are needed for patients with contraindications. Using a systematic literature search, clinical outcomes of remifentanil for labor pain have been summarized. Also, comparisons of remifentanil to other options including meperidine, epidural analgesia, fentanyl, and nitrous oxide are provided. Based on the literature review, remifentanil is associated with high overall maternal satisfaction and favorable side-effect profile. However, due to the low reporting of adverse events, large, randomized controlled trials are needed to evaluate maternal and neonatal safety adequately and determine the optimal dosing needed to provide effective analgesia. While remifentanil is a feasible alternative for patients who cannot or do not want to receive epidural analgesia, administration should be monitored closely for potential adverse effects.

    Objective: To discuss the clinical efficacy of CT-guided radioactive 125 I seed implantation treatment for unresectable pancreatic cancer. Methods: Forty patients with inoperable pancreatic cancer were enrolled in this study, including 25 males and 15 females with an median age of 69 years (38-89 years). Treatment planning system (TPS) was used to reconstruct 3-dimensional images of pancreatic tumor and to define the quantity and distribution of 125 I seeds. The radioactivity of 125 I seeds was 0.5 - 0.8 mCi / seed. The seeds were implanted into pancreatic tumor under CT guidance at intervals of 1 cm and were kept away from vessels, pancreatic duct and other adjacent important organs. The tumor matched peripheral dose (MPD) was 60-140 Gy. The median amount of implanted 125 I seeds was 36 (18-68) in number. CT scan was performed immediately after the procedure to check the quality of the seeds. In addition, 10 patients received concurrent chemotherapy with arterial infusion of gemcitabin and 5-fluororacil (5-Fu) for 3 to 4 therapeutic courses. Results: The median diameter of the tumors was 4.9 cm. The follow-up period was 2 to 28 months. After the treatment the refractory pain was significantly relieved (P 125 I seed implantation is a safe, effective and minimally-invasive brachytherapy for unresectable pancreatic cancer with reliable short-term efficacy. It has an excellent anti-pain effect. The curative results can be further improved when chemotherapy is employed together. However, its long-term efficacy needs to be observed. (authors)

    The study aim was to explore the clinical efficacy and safety of inhaled corticosteroids (ICS)/long-acting beta2-agonists (LABA) in combined with idiopathic pulmonary fibrosis and emphysema. 45 patients with combined idiopathic pulmonary fibrosis and emphysema (CPFE) who were treated with ICS/LABA (Group A), 24 patients with CPFE who were treated without ICS/LABA (Group B) and 35 patients with idiopathic pulmonary fibrosis (IPF) (Group C) were enrolled into this study. Then, clinical efficacy and safety of ICS/LABA was analyzed through lung function scores and lung high-resolution computed tomography (HRCT) scans. Compared with baseline levels, the FEV1%, FVC% and DLCO% levels were increased 11.2%, 13.53% and 12.8% respectively in group A, but declined 14.21%, 16.8% and 21.25% respectively in group B, meanwhile, lung HRCT score was declined 9.31 in group A but increased 14.87 in group B, and there was significant difference between group A and group B (P0.05). The incidence of adverse reaction was higher in group A than that in group B during this study, but there was no significant difference (P>0.05). ICS/LABA therapy could improve lung function condition in patients with CPFE and declined acute out-break frequency and severity of diseases during acute episode period.

    Pulmonary arterial hypertension (PAH) is an intractable and rare disease and the accumulation of clinical evidence under real-world setting is needed. A post-marketing surveillance for the endothelin receptor antagonist ambrisentan (Volibris tablet) has been conducted by all-case investigation since September 2010. This paper is an interim report on the safety and efficacy of ambrisentan in 702 patients with PAH. PAH patients aged 15 years or older were subjected to the analysis. The safety analysis by overall cases or stratification of patient backgrounds and the efficacy analysis were investigated. Regarding patient characteristics, the 702 patients subjected to safety analysis included 543 (77.4%) women and 546 (77.8%) patients at WHO functional class II/III. The mean observational time was 392.7 days. A total of 324 adverse drug reaction (ADR) occurred in 204 (29.1%) patients. Common ADRs (≥ 2%) included anemia (4.6%), peripheral edema (4.1%), headache (3.6%), edema and face edema (2.6% each), abnormal hepatic function (2.3%), and epistaxis (2.1%). There were 82 serious ADRs occurring in 44 (6.3%) patients (385 serious adverse events in 184 (26.2%) patients). Although 11 (1.6%) interstitial lung disease (ILD) cases were reported, all were observed in patients with disease that may contribute to ILD and therefore it is difficult to assess if ambrisentan was associated with these events. There was no difference in safety in relation to the presence/absence of connective tissue disease-related PAH (CTD-PAH) or combination therapy. Among 677 patients subjected to efficacy analysis, those in whom hemodynamic status was determined before and after treatment showed improvement in the mean pulmonary arterial pressure and pulmonary vascular resistance after treatment. The interim results showed safety consistent with the known profile of ambrisentan in terms of the types and frequencies of ADRs in patients with PAH in real clinical practice, in comparison with

    This study aims to explore the clinical efficacy of dexmedetomidine (DEX) in the diminution of fentanyl dosage in pediatric cardiac surgery based on some clinical and biochemical parameters. Fifty pediatric patients (American Society of Anesthesiologists II), 1-6 years old, were randomly allocated into two groups: group F (control group), in which patients received normal saline and high dosage of fentanyl (30 μg/kg), and group D, in which patients were given DEX and low dosage of fentanyl (15 μg/kg). Some hemodynamic and clinical parameters of the two groups were recorded. Furthermore, stress hormone (serum cortisol, norepinephrine, blood glucose) levels and cytokine (interleukin 6, tumor necrosis factor alpha) levels in the two groups were compared with each other. Stress hormone levels, cytokine levels, hemodynamic parameters and the consumption of sevoflurane did not differ between the two groups. Meanwhile, the extubation time was significantly shorter in Group D than F (Pfentanyl supplemented with DEX almost had the same anesthesia effects and inflammation extent compared with high dose of fentanyl, which suggested that infusion DEX might decrease fentanyl consumption in pediatric cardiac surgery.

    Full Text Available Suganthini Krishnan Natesan,1,2 Pranatharthi H Chandrasekar1 1Division of Infectious Diseases, Department of Internal Medicine, Wayne State University, 2John D Dingell VA Medical Center, Detroit, MI, USA Abstract: The majority of invasive mold infections diagnosed in immunocompromised cancer patients include invasive aspergillosis (IA and mucormycosis. Despite timely and effective therapy, mortality remains considerable. Antifungal agents currently available for the management of these serious infections include triazoles, polyenes, and echinocandins. Until recently, posaconazole has been the only triazole with a broad spectrum of anti-mold activity against both Aspergillus sp. and mucorales. Other clinically available triazoles voriconazole and itraconazole, with poor activity against mucorales, have significant drug interactions in addition to a side effect profile inherent for all triazoles. Polyenes including lipid formulations pose a problem with infusion-related side effects, electrolyte imbalance, and nephrotoxicity. Echinocandins are ineffective against mucorales and are approved as salvage therapy for refractory IA. Given that all available antifungal agents have limitations, there has been an unmet need for a broad-spectrum anti-mold agent with a favorable profile. Following phase III clinical trials that started in 2006, isavuconazole (ISZ seems to fit this profile. It is the first novel triazole agent recently approved by the United States Food and Drug Administration (FDA for the treatment of both IA and mucormycosis. This review provides a brief overview of the salient features of ISZ, its favorable profile with regard to spectrum of antifungal activity, pharmacokinetic and pharmacodynamic parameters, drug interactions and tolerability, clinical efficacy, and side effects.

    This study identifies and compares the individual cost components of hospital and ambulatory services that manage the care of hypertensive patients in eight countries: the US, the UK, France, Spain, Germany, Italy, Canada and Australia. Hypertension-related costs are classified according to four major cardiovascular events: (i) acute myocardial infarction; (ii) congestive heart failure; (iii) stroke; and (iv) renal failure, which was subdivided into renal failure treated by dialysis and renal failure treated by kidney transplantation. To make cross-country costs comparisons, we used the DRG codes used in the US and DRG-like codes from each country. US cost information was obtained from hypertension data available from the literature and health economics researchers. For costs in other countries, we consulted with national health economics experts in each country, used analyses by the Research Triangle Institute, and performed Medline and international literature searches. When available, we obtained information from the countries' public and private nationally representative data sources. For cross-country currency adjustments, all currencies were converted using the Purchasing Power Parities from the Organisation for Economic Cooperation and Development, and then converted into inflation-adjusted year 2000 US dollars. There exists considerable variation in hypertension-related costs from multinational clinical studies. This study documents that costs are generally higher in the US than in other countries; however, this is not always true. In particular, costs of treating heart failure in France and the costs of renal failure without transplantation in Germany and the UK are relatively high. While analysing multinational hypertensive cost data, this study also addresses the impact of cross-country cost variations on cost analyses. During the last decade, drug-development researchers have drawn extensively upon multinational trials to resolve enrollment problems and

    Basic fibroblast growth factor (bFGF) has been shown to promote wound healing. The present trial evaluated the clinical efficacy of bFGF for diabetic ulcer, a type of refractory skin ulcer, and the dose-response relationship. This was designed as a randomized, double-blind, dose-ranging, placebo-controlled trial. A total of 150 patients with non-ischaemic diabetic ulcers measuring 900 mm2 or less were randomized into a placebo group (n = 51), a 0.001% bFGF group (n = 49) and a 0.01% bFGF group (n = 50), and 148 of these patients received treatment for 8 weeks or less. The efficacy evaluation was carried out on 139 patients who met the protocol in this trial. The primary outcome was the percentage of patients showing 75% or greater reductions in the area of ulcer. The area of ulcer decreased by 75% or more in 57.5% (27/47), 72.3% (34/47), and 82.2% (37/45) in the placebo, 0.001% bFGF and 0.01% bFGF groups, respectively, and differences were significant between the 0.01% bFGF and placebo groups (p = 0.025). The cure rate was 46.8% (22/47), 57.4% (27/47), and 66.7% (30/45) in the placebo, 0.001% bFGF and 0.01% bFGF groups, respectively. The findings obtained in this trial showed wound healing accelerating effects of bFGF on diabetic ulcers.

    Full Text Available Pinky Agarwal1, Alida Griffith1, Henry R Costantino2, Narendra Vaish31Booth Gardner Parkinson’s Center, Kirkland, WA, USA; 2Costantino Consulting, Woodinville, WA, USA; 3Kirkland, WA, USAAbstract: Restless legs syndrome (RLS is a sleep-related movement disorder commonly involving an unpleasant urge to move the limbs, typically the legs. Dopaminergic agents represent the first-line therapy for RLS; however, long-term use of such drugs results in worsening symptoms due to “augmentation” or other adverse events. Gabapentin, an analog of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA, is an anticonvulsant/analgesic agent. Gabapentin is only mildly effective in relieving RLS symptoms, perhaps a result of its poor absorption from the gastrointestinal (GI tract. Gabapentin enacarbil is a prodrug of gabapentin specifically designed to enhance absorption via the GI tract, and hence provide improved circulating levels of gabapentin on metabolism. Clinical trials to date have demonstrated favorable safety and (compared to traditional gabapentin improved pharmacokinetics and efficacy in treating RLS symptoms. Thus, gabapentin enacarbil may prove to be a useful drug in treating RLS. An application of gabapentin enacarbil for treatment of RLS is currently pending with FDA for approval.Keywords: restless legs syndrome, gabapentin enacarbil, movement disorder

    Full Text Available Intracerebral hemorrhage (ICH is a subtype of stroke associated with high morbidity and mortality rates. No proven treatments are available for this condition. Iron-mediated free radical injury is associated with secondary damage following ICH. Deferoxamine (DFX, a ferric-iron chelator, is a candidate drug for the treatment of ICH. We performed a systematic review of studies involving the administration of DFX following ICH. In total, 20 studies were identified that described the efficacy of DFX in animal models of ICH and assessed changes in the brain water content, neurobehavioral score, or both. DFX reduced the brain water content by 85.7% in animal models of ICH (-0.86, 95% CI: -.48- -0.23; P < 0.01; 23 comparisons, and improved the neurobehavioral score by -1.08 (95% CI: -1.23- -0.92; P < 0.01; 62 comparisons. DFX was most efficacious when administered 2-4 h after ICH at a dose of 10-50 mg/kg depending on species, and this beneficial effect remained for up to 24 h postinjury. The efficacy was higher with phenobarbital anesthesia, intramuscular injection, and lysed erythrocyte infusion, and in Fischer 344 rats or aged animals. Overall, although DFX was found to be effective in experimental ICH, additional confirmation is needed due to possible publication bias, poor study quality, and the limited number of studies conducting clinical trials.

    Hypertension is a prevalent disease among African Americans, and successful treatment rates are low. Since calcium channel blockers are well-tolerated and efficacious in African Americans, we undertook this study to compare the efficacy, safety, and tolerability of 3 commonly prescribed calcium channel blockers: amlodipine besylate (Norvasc), nifedipine coat core (CC) (Adalat CC), and nifedipine gastrointestinal therapeutic system (GITS) (Procardia XL). One hundred ninety-two hypertensive patients across 10 study centers were randomly assigned to double-blind monotherapy with amlodipine besylate (5 mg/d), nifedipine CC (30 mg/d), or nifedipine GITS (30 mg/d) for 8 weeks. Patients not achieving therapeutic response after 4 weeks had their dose doubled for the next 4 weeks. The primary end point was a comparison of the average reduction (week 8 minus baseline) in 24-hour ambulatory diastolic blood pressure (DBP). Secondary end points included a comparison of average 24-hour ambulatory systolic blood pressure (SBP), office SBP or DBP reduction, responder rates, safety, and tolerability. One hundred sixty-three patients were evaluable for efficacy after 8 weeks. There was no significant difference in the average 24-hour ambulatory DBP (-8.5, -9.0, and -6.1 mm Hg, respectively) or SBP (-14.3, -15.7, and -11.8 mm Hg, respectively) reduction. Average office SBP and DBP were reduced to a comparable degree (19-22 mm Hg [P =.50] and 12-14 mm Hg [P =.51], respectively). Responder rates (DBP or = 10 mm Hg) were similar (P = .38). Discontinuation rates and adverse event frequency were distributed similarly across the 3 treatment groups. The efficacy, safety, and tolerability of the 3 dihydropyridine calcium channel blockers are equivalent in African Americans with stages 1 and 2 hypertension.

    Essentials rVIII-SingleChain is a novel recombinant factor VIII with covalently bonded heavy and light chains. Efficacy, safety and pharmacokinetics were studied in pediatric patients with severe hemophilia A. Across all prophylaxis regimens, the median annualized spontaneous bleeding rate was 0.00. rVIII-SingleChain showed excellent hemostatic efficacy and a favorable safety profile. Background rVIII-SingleChain is a novel B-domain truncated recombinant factor VIII (rFVIII) comprised of covalently bonded FVIII heavy and light chains, demonstrating a high binding affinity to von Willebrand factor. Objectives This phase III study investigated the safety, efficacy and pharmacokinetics of rVIII-SingleChain in previously treated pediatric patients hemophilia A. Patients/Methods Patients could be assigned to prophylaxis or on-demand therapy by the investigator. For patients assigned to prophylaxis, the treatment regimen and dose were based on the bleeding phenotype. For patients receiving on-demand therapy, dosing was guided by World Federation of Hemophilia recommendations. The primary endpoint was treatment success, defined as a rating of 'excellent' or 'good' on the investigator's clinical assessment of hemostatic efficacy for all treated bleeding events. Results The study enrolled 84 patients (0 to 50 EDs. In the 347 bleeds treated and evaluated by the investigator, hemostatic efficacy was rated as excellent or good in 96.3%. The median annualized spontaneous bleeding rate was 0.00 (Q1, Q3: 0.00, 2.20), and the median annualized bleeding rate was 3.69 (Q1, Q3: 0.00, 7.20) across all prophylaxis regimens. No participant developed an inhibitor.

Secondary efficacy end-points included scores for Clinical Global Improvement (CGI)-Examiner during ON time, Unified Parkinson's Disease Rating Scale (UPDRS)-ADL during OFF time, UPDRS-Motor during ON time and total daily ON time with and without troublesome dyskinesia. Tolerability was evaluated from adverse events (AEs) in the two age groups. Rasagiline decreased daily OFF time versus placebo (Prasagiline but were not significant. Between-group comparisons (≥70 vs. efficacy was unaffected by age for all end-points (P>0.1), and rasagiline was well tolerated amongst both groups of patients with a comparable incidence of total and dopaminergic AEs (P>0.1). Adjunct rasagiline is efficacious and well tolerated in elderly non-demented patients (≥70 years) with moderate to advanced PD. Confirmation of the efficacy and safety of rasagiline in the elderly patient subgroup is especially relevant because of the increasing number of elderly patients with PD. © 2011 The Author(s).

    Targeted agents such as sunitinib, an oral, multitargeted receptor tyrosine kinase inhibitor, have greatly improved the prognosis for patients with metastatic renal cell carcinoma (mRCC). In this review we analyse data from sunitinib preclinical and clinical studies in detail and consider the key implications for the effective use of sunitinib in clinical practice. Sunitinib has shown efficacy and acceptable tolerability in patients with mRCC in phase II and III clinical studies. In a pivotal phase III study in treatment-naïve patients with mRCC, median progression-free survival for sunitinib-treated patients was double of that with interferon-α (P relationship between clinical end points and sunitinib exposure showed that increased sunitinib exposure was associated with a greater probability of objective response, longer time to tumour progression and overall survival, as well as some increased risk of specific adverse events. It is important to consider the relationship between exposure and response to maximize clinical benefit from sunitinib treatment.

    Full Text Available BACKGROUND: Schistosomiasis and opisthorchiasis are of public health importance in Southeast Asia. Praziquantel (PZQ is the drug of choice for morbidity control but few dose comparisons have been made. METHODOLOGY: Ninety-three schoolchildren were enrolled in an area of Lao PDR where Schistosoma mekongi and Opisthorchis viverrini coexist for a PZQ dose-comparison trial. Prevalence and intensity of infections were determined by a rigorous diagnostic effort (3 stool specimens, each examined with triplicate Kato-Katz before and 28-30 days after treatment. Ninety children with full baseline data were randomized to receive PZQ: the 40 mg/kg standard single dose (n = 45 or a 75 mg/kg total dose (50 mg/kg+25 mg/kg, 4 hours apart; n = 45. Adverse events were assessed at 3 and 24 hours posttreatment. PRINCIPAL FINDINGS: Baseline infection prevalence of S. mekongi and O. viverrini were 87.8% and 98.9%, respectively. S. mekongi cure rates were 75.0% (95% confidence interval (CI: 56.6-88.5% and 80.8% (95% CI: 60.6-93.4% for 40 mg/kg and 75 mg/kg PZQ, respectively (P = 0.60. O. viverrini cure rates were significantly different at 71.4% (95% CI: 53.4-84.4% and 96.6% (95% CI: not defined, respectively (P = 0.009. Egg reduction rates (ERRs against O. viverrini were very high for both doses (>99%, but slightly lower for S. mekongi at 40 mg/kg (96.4% vs. 98.1% and not influenced by increasing diagnostic effort. O. viverrini cure rates would have been overestimated and no statistical difference between doses found if efficacy was based on a minimum sampling effort (single Kato-Katz before and after treatment. Adverse events were common (96%, mainly mild with no significant differences between the two treatment groups. CONCLUSIONS/SIGNIFICANCE: Cure rate from the 75 mg/kg PZQ dose was more efficacious than 40 mg/kg against O. viverrini but not against S. mekongi infections, while ERRs were similar for both doses.

    Desonide is a low-potency topical corticosteroid that has been used for decades in the treatment of steroid-responsive dermatoses. The favorable safety profile of this topical agent makes it ideal for patients of all ages. This article provides a review of desonide's history, pharmacodynamic properties, vehicle technology, efficacy and safety. Randomized controlled trials, as well as open-label and non-comparative studies, case series and reports, experimental models, and data from the Galderma pharmacovigiliance program were reviewed in order to address the clinical efficacy and safety of desonide. Clinical efficacy and safety have been proven in multiple clinical trials. In addition to cream, lotion and ointment formulations, the recently developed hydrogel and foam preparations have increased desonide's versatility and patient tolerability.

  10. [Note on the epistemology of clinical pharmacology: comparison with the approach of Karl Popper].

    Science.gov (United States)

    Boissel, J P

    1999-01-01

    Is clinical pharmacology a science or only an application of science? Karl Popper suggested a method to identify science and to sort it out from other logical activities such as metaphysics, whereby the falsification criterion he proposed can apply to the theory in such a way that the theory could be refuted. The clinical pharmacologist's approach requires the build-up of a therapeutic model on the basis of two other models: the physiopathologic and the pharmacological. The three-model construct is a theory. Is it scientific in the Popperian sense? From the therapeutic model, one can predict the efficacy of a drug, and the corresponding statement is tested by a clinical trial. Whatever the original statement, it is modified into a refutable one because of the use of the statistical approach in clinical trials. Furthermore, the predicate represents a hypothesis of the model validity, which will then be confronted with 'reality' through clinical experiment. As the therapeutic model is refutable, clinical pharmacology is a science in the Popperian sense.

    To evaluate the efficacy and safety of topical diquafosol ophthalmic solution for treatment of dry eye. Randomized clinical trials (RCTs) from MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) were identified to evaluate the efficacy and safety of topical administration of diquafosol to patients with dry eyes. Data evaluation was based on endpoints including Schirmer test, tear film break-up time, ocular surface staining score, subjective symptom score, and adverse events. A total of 8 RCTs involving 1516 patients were selected based on the prespecified criteria. Significant improvement of Schirmer test values and tear film break-up time were reported in 40% (2 of 5) and 80% (4 of 5) studies, respectively. Ocular surface staining scores significantly decreased in 100% (fluorescein corneal staining, 6 of 6; Rose Bengal corneal and conjunctival staining, 4 of 4) RCTs. Symptoms significantly improved in 75% (6 of 8) RCTs in patients with dry eyes. No severe adverse events were reported with the concentration of diquafosol from 0.5% to 5%. Heterogeneity in study design prevented meta-analysis from statistical integration and summarization. Topical diquafosol seems to be a safe therapeutic option for the treatment of dry eye. The high variability of the selected RCTs compromised the strength of evidence and limits the determination of efficacy. However, the topical administration of diquafosol seems to be beneficial in improving the integrity of the epithelial cell layer of the ocular surface and mucin secretion in patients with dry eyes. This review indicates a need for standardized criteria and methods for evaluation to assess the efficacy of diquafosol in the future clinical trials.

    Full Text Available Objective To analyze the clinical efficacy and safety of sunitinib combined with autologous dentritic cell (DC and cytokine induced killer cell (CIK for patients suffering from metastatic renal cell carcinoma (mRCC. Methods Clinical data of 27 mRCC patients treated with sunitinib combined with autologous DC and CIK were reviewed retrospectively. Efficacy, quality of life, immunology and safety of this treatment were evaluated. Results Follow-up time ranged from 4 to 25 months. Out of all the patients, sunitinib was reduced in 1 and discontinued in 2 due to side effects; 1 patient quit for personal reasons; 14 patients developed progressive disease. The progression-free survival (PFS was 4 to 19.5 months. Ten patients died from tumor, the overall survival time (OS was 6 to 21 months. The median PFS was 16 months (95%CI 12.5-19.5. The OS was not achieved. The efficacy was evaluated according to Response Evaluation Criteria in Solid Tumors (RECIST. All the patients received treatment over 1 cycle. After one course of treatment, among 27 patients, 0 had complete remission (CR, 4 had partial remission (PR, 17 had stable disease (SD, and 6 had progressive disease (PD. The overall objective remission rate (ORR and disease control rate (DCR were 14.8% (4/27 and 77.8% (21/27, respectively. Sunitinib and autologous transfusion of DC and CIK improved the immune function and quality of life. The major adverse events were fatigue, hand-foot syndrome, hypertension, hypothyroidism, thrombocytopenia, neutropenia and fever. Most of the adverse events were ameliorated by supportive treatment or dose reduction. Conclusions  Sunitinib combined with autologous DC and CIK may be beneficial in the treatment of mRCC with acceptable toxic reactions, and it may be considered as a new approach for the comprehensive treatment of RCC.

    2016-01-01

    Abstract Although turmeric and its curcumin-enriched extracts have been used for treating arthritis, no systematic review and meta-analysis of randomized clinical trials (RCTs) have been conducted to evaluate the strength of the research. We systemically evaluated all RCTs of turmeric extracts and curcumin for treating arthritis symptoms to elucidate the efficacy of curcuma for alleviating the symptoms of arthritis. Literature searches were conducted using 12 electronic databases, including PubMed, Embase, Cochrane Library, Korean databases, Chinese medical databases, and Indian scientific database. Search terms used were “turmeric,” “curcuma,” “curcumin,” “arthritis,” and “osteoarthritis.” A pain visual analogue score (PVAS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were used for the major outcomes of arthritis. Initial searches yielded 29 articles, of which 8 met specific selection criteria. Three among the included RCTs reported reduction of PVAS (mean difference: −2.04 [−2.85, −1.24]) with turmeric/curcumin in comparison with placebo (P < .00001), whereas meta-analysis of four studies showed a decrease of WOMAC with turmeric/curcumin treatment (mean difference: −15.36 [−26.9, −3.77]; P = .009). Furthermore, there was no significant mean difference in PVAS between turmeric/curcumin and pain medicine in meta-analysis of five studies. Eight RCTs included in the review exhibited low to moderate risk of bias. There was no publication bias in the meta-analysis. In conclusion, these RCTs provide scientific evidence that supports the efficacy of turmeric extract (about 1000 mg/day of curcumin) in the treatment of arthritis. However, the total number of RCTs included in the analysis, the total sample size, and the methodological quality of the primary studies were not sufficient to draw definitive conclusions. Thus, more rigorous and larger studies are needed to confirm the therapeutic efficacy

    2016-04-01

    Conclusion: With regard to the low mean score of self-efficacy of older adults residing in nursing homes, the authorities of nursing homes should pay attention to the needs of older adults and provide general education about promoting the tradition of caring older people by their families. Furthermore, all institutions and organizations that have important goals such as healthy older adults should advance toward their goals by planning, education, and consultation with families that care about their older adults. Finally, with regard to the results about the association of self-efficacy with loneliness, self-efficacy assessment should be considered one of the effective factors in psychological dimensions of the people and a way to support the self-care of older adults because promoting self-efficacy will result in managing stress and improving the mental health.

    Andrographolide sulfonate treatment has been shown to improve clinical severe hand, foot, and mouth disease (HFMD) efficacies when combined with conventional therapy. However, the mechanisms for its therapeutic effects remain elusive. In this study, we aimed to investigate whether andrographolide sulfonate exerts its efficacy by acting on neutrophil activation. We obtained serial plasma samples at two time points (before and after 5 days of therapy) from 28 HFMD patients who received conventional therapy and 18 patients who received combination therapy (andrographolide sulfonate plus conventional therapy). Then, we measured plasma myeloperoxidase (MPO), S100A8/A9, histone, and inflammatory cytokine levels. Furthermore, we examined if andrographolide sulfonate had direct effects on neutrophil activation in vitro. We observed that MPO and S100A8/A9 levels were markedly elevated in the HFMD patients before clinical treatment. At 5 days post-medication, the MPO, S100A8/A9, histone, and interleukin-6 levels were markedly lower in the combination therapy group compared with the conventional therapy group. In vitro studies showed that andrographolide sulfonate inhibited lipopolysaccharide-stimulated neutrophil activation, demonstrated by the decreased production of reactive oxygen species and cytokines. These data indicate that neutrophil activation modulation by andrographolide sulfonate may be a critical determinant for its clinical HFMD treatment efficacy. Copyright © 2015 John Wiley & Sons, Ltd.

  20. The forgotten role of alcohol: a systematic review and meta-analysis of the clinical efficacy and perceived role of chlorhexidine in skin antisepsis.

    Directory of Open Access Journals (Sweden)

    Matthias Maiwald

    Full Text Available BACKGROUND: Skin antisepsis is a simple and effective measure to prevent infections. The efficacy of chlorhexidine is actively discussed in the literature on skin antisepsis. However, study outcomes due to chlorhexidine-alcohol combinations are often attributed to chlorhexidine alone. Thus, we sought to review the efficacy of chlorhexidine for skin antisepsis and the extent of a possible misinterpretation of evidence. METHODS: We performed a systematic literature review of clinical trials and systematic reviews investigating chlorhexidine compounds for blood culture collection, vascular catheter insertion and surgical skin preparation. We searched PubMed, CINAHL, the Cochrane Library, the Agency for Healthcare Research and Quality website, several clinical trials registries and a manufacturer website. We extracted data on study design, antiseptic composition, and the following outcomes: blood culture contamination, catheter colonisation, catheter-related bloodstream infection and surgical site infection. We conducted meta-analyses of the clinical efficacy of chlorhexidine compounds and reviewed the appropriateness of the authors' attribution. RESULTS: In all three application areas and for all outcomes, we found good evidence favouring chlorhexidine-alcohol over aqueous competitors, but not over competitors combined with alcohols. For blood cultures and surgery, we found no evidence supporting chlorhexidine alone. For catheters, we found evidence in support of chlorhexidine alone for preventing catheter colonisation, but not for preventing bloodstream infection. A range of 29 to 43% of articles attributed outcomes solely to chlorhexidine when the combination with alcohol was in fact used. Articles with ambiguous attribution were common (8-35%. Unsubstantiated recommendations for chlorhexidine alone instead of chlorhexidine-alcohol were identified in several practice recommendations and evidence-based guidelines. CONCLUSIONS: Perceived efficacy

    Diarrhoea is responsible for high rates of infant morbidity and mortality. It is multifactorial, manifested by socioeconomic, hygienic, and maternal factors. The aim of this study is to evaluate the effects of an educational video on maternal self-efficacy for the prevention of childhood diarrhoea. This was a randomized trial conducted in the state of Ceará, Brazil. Participants were 2 groups (comparison and intervention), composed of mothers of children under 5 years of age. Group membership was allocated by cluster randomization. Outcomes were maternal self-efficacy measured using the Maternal Self-efficacy Scale for Prevention of Early Childhood Diarrhoea; outcome data collectors were blinded to group allocation. Ninety participants were randomized to each group; 83 intervention group and 80 comparison group members were contained in the final analysis. Maternal self-efficacy in preventing childhood diarrhoea increased in both groups, but average scores of the intervention group were higher at all time than those of the comparison group. The educational video had a significant effect on maternal self-efficacy. © 2017 John Wiley & Sons Australia, Ltd.

    Enhancing therapeutic efficacy is essential for successful treatment of chemoresistant cancers such as metastatic hormone-refractory prostate cancer (HRPC). To improve the efficacy of doxorubicin (DOX) for treating chemoresistant disease, the feasibility of using nanodiamond (ND) particles was investigated. Utilizing the pH responsive properties of ND, a novel protocol for complexing NDs and DOX was developed using a pH 8.5 coupling buffer. The DOX loading efficiency, loading on the NDs, and pH responsive release characteristics were determined utilizing UV-Visible spectroscopy. The effects of the ND-DOX on HRPC cell line PC3 were evaluated with MTS and live/dead cell viability assays. ND-DOX displayed exceptional loading efficiency (95.7%) and drug loading on NDs (23.9 wt%) with optimal release at pH 4 (80%). In comparison to treatment with DOX alone, cell death significantly increased when cells were treated with ND-DOX complexes demonstrating a 50% improvement in DOX efficacy. Of the tested treatments, ND-DOX with 2.4 μg mL(-1) DOX exhibited superior efficacy (60% cell death). ND-DOX with 1.2 μg mL(-1) DOX achieved 42% cell death, which was comparable to cell death in response to 2.4 μg mL(-1) of free DOX, suggesting that NDs aid in decreasing the DOX dose necessary to achieve a chemotherapeutic efficacy. Due to its enhanced efficacy, ND-DOX can be used to successfully treat HRPC and potentially decrease the clinical side effects of DOX.

    The purpose of the present study was to compare the clinical efficacy between a flowable-type nano-hybrid composite and a paste-type composite for posterior restoration. Of 62 posterior teeth in 33 patients (mean age: 34.1 years), 31 were filled with a paste-type composite (Heliomolar [HM] group), and another 31 with a flowable nano-hybrid composite (MI FIL [MI] group). Clinical efficacy was evaluated at 2 years after the restoration. There were no differences for retention, surface texture deterioration, anatomical form change, deterioration of marginal adaptation, and secondary caries, while a statistical difference was found for marginal discoloration, which was significantly greater in the HM group (P < 0.05). Furthermore, color matching in the MI group was superior to that in the HM group immediately after the restoration throughout the study period. The present 2-year clinical evaluation of different composites showed that the flowable nano-hybrid composite could be an effective esthetic material for posterior restoration. © 2016 John Wiley & Sons Australia, Ltd.

    2011-01-01

    Full Text Available Ramelteon is a tricyclic synthetic analog of melatonin that acts specifically on MT 1 and MT 2 melatonin receptors. Ramelteon is the first melatonin receptor agonist approved by the Food and Drug Administration (FDA for the treatment of insomnia characterized by sleep onset difficulties. Ramelteon is both a chronobiotic and a hypnotic that has been shown to promote sleep initiation and maintenance in various preclinical and in clinical trials. The efficacy and safety of ramelteon in patients with chronic insomnia was initially confirmed in short-term placebo-controlled trials. These showed little evidence of next-day residual effects, withdrawal symptoms or rebound insomnia. Other studies indicated that ramelteon lacked abuse potential and had a minimal risk of producing dependence or adverse effects on cognitive or psychomotor performance. A 6-month placebo-controlled international study and a 1-year open-label study in the USA demonstrated that ramelteon was effective and well tolerated. Other potential off-label uses of ramelteon include circadian rhythm sleep disorders such as shift-work and jet lag. At the present time the drug should be cautiously prescribed for short-term treatment only.

    Lercanidipine, a long-acting dihydropyridine with a good antihypertensive efficacy and tolerability in clinical use. With the aim to determine the efficacy and tolerability of this drug in usual clinical practice we performed the ELYPSE trial. Grade 1 or 2 essential hypertensive patients in whom their physicians considered to prescribe a dihydropyridine were conferred to Lercanidipine 10 mg once daily with a 3-month follow-up; 9059 patients were included (age: 63 +/- 11 years; 58% women, 60% over 60 years, 56% grade 2 hypertensives and 69% previously treated with other antihypertensive drugs). A subgroup of 1267 patients (14%) who were included in the study had experienced adverse reactions with other drugs. Electronic case-report forms and a central database (Internet) were used in this trial. At baseline, blood pressure (BP) was 160.1 +/- 10.2/95.6 +/- 6.6 mmHg; and heart rate (HR) 77.3 +/- 9.3 beats/min. Significant reductions in both systolic and diastolic BP were attained at 1 month with slight additional decreases 2 months later. At 3 months, BP was 141.4 +/- 11.3/ 83.1 +/- 6.9 mmHg, and HR 75.2 +/- 8.2 beats/min (p < 0.001 versus baseline). At the study end. 64% of the patients achieved a diastolic BP < 90 mmHg, BP control (< 140/90 mmHg) was attained in 32%. In the subgroup of diabetics (n = 1269) an adequate BP control (< 130/85) was attained in only 16.4%. The overall incidence of adverse events was 6.5%, of which the most frequent were headache (2.9%), ankle oedema (1.2%), flushing (1.1%) and palpitations (0.6%). Withdrawal rate was < 1%. The efficacy and tolerability in the subgroup of patients included in the study due to adverse events with other drugs were similar to the whole study group. In this study Lercanidipine has shown a good efficacy and tolerability in daily clinical practice. These findings are concordant with those reported in randomized controlled trials.

    Objective: To explore the clinical efficacy and safety of transcatheter absolute ethanol injection treatment on varicose veins of lower extremity. Methods: twenty-there patients with 25 varicose veins of lower extremity were treated by puncture of great saphenous vein above 1-2 cm of complicated inner ankle, perforating catheter to the point below the 3-4 cm of the conjunction of great saphenous vein and Femoral vein and pressing the conjunction of these two veins. Under the monitor of DSA, inject the absolute ethanol slowly while retrieve the catheter little by little (one limb with varicose veins injected total volume 15-20 mi), in the mean time, using contrast agent to monitor the level of embolism until the formation of total embolism in the all great saphenous veins. Results: All the cases were retrospectively followed up with CDFI examination after 3-12 months of the surgery, No blood flow were seen in the 25 embolismic great saphenous vein. Clinical symptom were alleviated obviously after 2-3 weeks of treatment; varicose veins were collapse after 3 to 7 days. Two cases of leg ulceration were healed after 4 to 6 weeks of operation. 20 limbs were found mild swelling in the 2 day after the surgery. However, all the cases were disappeared after 1 to 2 weeks; 4 treated limbs developed delayed paresthesia in the 3 day after the surgery, and recovered totally in the 2 weeks. No complications of deep vein thrombosis, lung thrombosis etc al, were found after operation. Conclusions: Using transcatheter injection of absolute ethanol to treat varicose veins of lower extremity has the advantage of less invasion, more safety and low appearance of complications. The short term efficacy is solid while the long term effect needs further evaluation. (authors)

    The MAO-B inhibitor rasagiline is indicated for the treatment of idiopathic Parkinson's disease (PD), and its use is supported by evidence from large-scale, controlled clinical studies. The post-marketing observational study presented here investigated the efficacy and tolerability of rasagiline treatment (monotherapy or combination therapy) in daily clinical practice. The study included patients with idiopathic PD who received rasagiline (recommended dose 1 mg, once daily) as monotherapy or combination therapy. The treatment and observation period was approximately 4 months. Outcome measures included the change from baseline in the Columbia University Rating Scale (CURS), the Unified PD Rating Scale fluctuation subscale, daily OFF time (patient home diaries) and the PD Questionnaire-39. Adverse drug reactions/adverse events (ADRs/AEs) and the physician's global judgement of tolerability and efficacy were also examined. Overall, 754 patients received rasagiline during the study. Patients treated with rasagiline (monotherapy or combination therapy) showed significant improvements from baseline in symptom severity (including classical motor and non-classical motor/non-motor symptoms) and quality of life (QoL). Patients receiving combination therapy also experienced significant reductions in daily OFF time. Tolerability was rated as good/very good in over 90% of patients. In daily clinical practice, monotherapy or combination therapy with rasagiline is able to improve PD symptoms, reduce OFF time, and improve QoL, whilst demonstrating favourable tolerability. In addition, rasagiline has a simple dosing schedule of one tablet, once daily, with no titration. These results are consistent with the pivotal rasagiline clinical studies (TEMPO, LARGO and PRESTO).

    to examine the effects of nurse-led, problem-solving therapy (PST) on coping, self-efficacy and depressive symptoms for patients with chronic obstructive pulmonary disease (COPD) using a randomised controlled trial. a total of 254 patients with COPD were recruited, screened and randomly allocated into the intervention group with nurse-led PST or the comparison group with usual care. A total of 151 patients (intervention = 78 and comparison = 73) completed the study for 6 months. the nurse-led PST was an individualised and patient-centred intervention to improve patients' problem-solving skills related to symptom management and lifestyle modification. Twelve telephone-based PST sessions were provided to the intervention group, while the control group received usual care from their primary care providers. there were no group differences of post-test scores in problem-oriented coping, self-efficacy and depressive symptoms between the two groups. However, despite the lack of group differences, the nurse-led PST was effective for clinically depressed patients with COPD, who experienced decreased depressive symptoms (mean difference = 6.8, P = 0.009) and increased self-efficacy (mean difference = -0.6, P = 0.041) in the intervention group (n = 12). the nurse-led PST offered to patients with COPD did not demonstrate any different effects compared with usual care over 6 months; however, a subgroup analysis with clinically depressed subjects showed improved self-efficacy and decreased depressive symptoms in the intervention group. © The Author 2014.

    Objective: To study the clinical spectrum of seizures and efficacy of anticonvulsive treatment in children. Study Design: A descriptive study. Place and Duration of Study: Military Hospital (MH) Rawalpindi from October 2011 to March 2012. Material and Methods: One hundred children of either gender aged 1 month to 12 years presenting with seizures at Military Hospital Rawalpindi were evaluated and consented to participate in the study. All children with a febrile seizures were evaluated. The seizures were classified according to international league against epilepsy guidelines. Antiepileptic treatment regimen was evaluated in terms of number of drugs, correct dosage and efficacy in control of seizures. Results: It was observed that generalized seizures were (58 percent) followed by focal seizures (32 percent) in children. Valproic acid was prescribed in (51 percent) cases. Epilepsy was diagnosed in (56 percent) followed by cerebral palsy (20 percent), post meningoencephalitis sequalae (11 percent), intracranial hemorrhage (7 percent) and leukodystrophies (3 percnet) as underlying cause of seizures. Statistically significant association was seen between age groups and diagnosis (p value=0.001); age groups and types of seizures (p value=0.046); correct dosage of antiepileptics and control of seizures (p value=0.007); compliance to treatment and control of seizures (p value=0.007). Conclusion: Generalized seizures are the commonest form followed by focal seizures. Epilepsy was the common etiology of seizures in all age groups in children. Cerebral palsy was the second leading cause of seizures in children followed by post meningoencephalitis, stroke and leukodystrophies. Valproic acid was the most commonly prescribed antiepileptic. Normal delivery with delayed cry was the major risk factor for cerebral palsy. Prescription of appropriate antiepileptics according to diagnosis in optimum dosage and compliance to treatment affect control of seizures in children. (author)

    Clinical pharmacology and efficacy of flomoxef (FMOX) in neonates were investigated. And the following results were obtained. 1. Mean serum concentrations of FMOX at 30 minutes after administration were 24.3 micrograms/ml, 47.6 micrograms/ml, and 85.8 micrograms/ml at doses of 10 mg/kg, 20 mg/kg, and 40 mg/kg administered, respectively. 2. Mean serum half-lives of FMOX were 3.4 hours in 0-3 day-old neonates, and 2.6 hours in 4 day-old or older subjects. 3. A dose response was evident among different dose groups given 10 mg/kg, 20 mg/kg, and 40 mg/kg. 4. Urinary recovery rates of FMOX in the first 6 hours after administration ranged between 12.8 and 51.1%. 5. FMOX was effective in 7 out of 8 cases in which causative pathogens were identified. 6. Diarrhea was observed in 1 case as a side effect of the drug, but the symptom was relieved soon after the completion of the treatment. There was no case in which any abnormal laboratory results were observed. 7. FMOX has a broad spectrum of activities against Gram-positive and Gram-negative aerobes and anaerobes. It is stable against most of beta-lactamases. It was demonstrated to be highly effective in our study, and yet without any serious side effects. FMOX is therefore considered to be one of the useful agents of the first choice for the treatment of bacterial infections such as sepsis and urinary tract infections in neonates and infants.

    The objective of this study was to evaluate the efficacy of intramammary treatment with ceftiofur hydrochloride of nonsevere, clinical coliform mastitis. One hundred four cases on 5 farms met the enrollment criteria for the study. Escherichia coli was the most common coliform species identified in milk samples from cows with mild to moderate clinical mastitis, followed by Klebsiella spp. and Enterobacter spp. At enrollment, a milk sample from the affected quarter was taken and used for on-farm culture or submitted to the laboratory. For cows in the treatment group, treatment was initiated with ceftiofur hydrochloride via intramammary infusion at 24-h intervals for 5 d according to label standards. Cows in the control group did not receive treatment. Culture results were available on the day after enrollment and only cows with coliform mastitis continued in the treatment and untreated control groups. Bacteriological cure was defined based on 2 posttreatment milk samples. Molecular typing was used for final definition of bacteriological cure. Treatment of nonsevere clinical gram-negative mastitis with ceftiofur hydrochloride resulted in a significant increase in bacteriological cure compared with nontreated controls in animals infected with E. coli or Klebsiella spp. Treated animals clinically improved significantly more compared with control cows. No significant differences were observed between treated and control animals in milk production or linear score before or after clinical mastitis. Treated animals left the study less frequently compared with control animals. Copyright © 2011 American Dairy Science Association. Published by Elsevier Inc. All rights reserved.

MethodsA total of 92 patients with alcoholic hepatitis who were admitted to our hospital from February 2011 to February 2014 were recruited in this study and randomly divided into two groups. The control group (n=46 was treated with conventional therapy combined with compound ammonium glycyrrhetate S. The test group (n=46 was treated with puerarin in addition to the regimen used in the control group. After 20 days of treatment, the levels of total bilirubin (TBil, alanine aminotransferase (ALT, aspartate aminotransferase (AST, glutamyl transpeptidase (GGT, albumin (Alb, Glasgow alcoholic hepatitis score (GAHS, and abdominal ultrasound were measured and compared with the results before the treatment in both groups. The clinical efficacy and adverse reactions in the two groups were also compared. ResultsAfter the treatment, the GAHSs and levels of TBil, ALT, AST, and GGT in the two groups were all significantly lower than those before the treatment (all P<0.05. In the test group after the treatment, the levels of TBil (20.96±6.85 μmol/L, ALT (33.72±14.18 U/L, and AST (38.69±6.38 U/L were all significantly lower than those in the control group (all P<0.05. The marked response rate, overall response rate, and rate of improvement in abdominal ultrasound in the test group were 63.04%, 93.48%, and 44.44%, respectively, all significantly higher than those in the control group (all P<0.05. There was no significant difference in adverse reactions between the two groups (P>0.05. ConclusionFor patients with alcoholic hepatitis, the combined therapy with puerarin and compound ammonium glycyrrhetate S can improve the treatment outcome and protect the liver function, and it has high safety and holds promise for clinical application.

  14. Preclinical antivenom-efficacy testing reveals potentially disturbing deficiencies of snakebite treatment capability in East Africa.

    Full Text Available Antivenom is the treatment of choice for snakebite, which annually kills an estimated 32,000 people in sub-Saharan Africa and leaves approximately 100,000 survivors with permanent physical disabilities that exert a considerable socioeconomic burden. Over the past two decades, the high costs of the most polyspecifically-effective antivenoms have sequentially reduced demand, commercial manufacturing incentives and production volumes that have combined to create a continent-wide vacuum of effective snakebite therapy. This was quickly filled with new, less expensive antivenoms, many of which are of untested efficacy. Some of these successfully marketed antivenoms for Africa are inappropriately manufactured with venoms from non-African snakes and are dangerously ineffective. The uncertain efficacy of available antivenoms exacerbates the complexity of designing intervention measures to reduce the burden of snakebite in sub-Saharan Africa. The objective of this study was to preclinically determine the ability of antivenoms available in Kenya to neutralise the lethal effects of venoms from the most medically important snakes in East Africa.We collected venom samples from the most medically important snakes in East Africa and determined their toxicity in a mouse model. Using a 'gold standard' comparison protocol, we preclinically tested the comparative venom-neutralising efficacy of four antivenoms available in Kenya with two antivenoms of clinically-proven efficacy. To explain the variant efficacies of these antivenoms we tested the IgG-venom binding characteristics of each antivenom using in vitro IgG titre, avidity and venom-protein specificity assays. We also measured the IgG concentration of each antivenom.None of the six antivenoms are preclinically effective, at the doses tested, against all of the most medically important snakes of the region. The very limited snake polyspecific efficacy of two locally available antivenoms is of concern. In vitro

    Recent evidence suggests that music-based interventions can be beneficial in maintaining cognitive, emotional, and social functioning in persons with dementia (PWDs). Our aim was to determine how clinical, demographic, and musical background factors influence the cognitive and emotional efficacy of caregiver-implemented musical activities in PWDs. In a randomized controlled trial, 89 PWD-caregiver dyads received a 10-week music coaching intervention involving either singing or music listening or standard care. Extensive neuropsychological testing and mood and quality of life (QoL) measures were performed before and after the intervention (n = 84) and six months later (n = 74). The potential effects of six key background variables (dementia etiology and severity, age, care situation, singing/instrument playing background) on the outcome of the intervention were assessed. Singing was beneficial especially in improving working memory in PWDs with mild dementia and in maintaining executive function and orientation in younger PWDs. Music listening was beneficial in supporting general cognition, working memory, and QoL especially in PWDs with moderate dementia not caused by Alzheimer's disease (AD) who were in institutional care. Both music interventions alleviated depression especially in PWDs with mild dementia and AD. The musical background of the PWD did not influence the efficacy of the music interventions. Our findings suggest that clinical and demographic factors can influence the cognitive and emotional efficacy of caregiver-implemented musical activities and are, therefore, recommended to take into account when applying and developing the intervention to achieve the greatest benefit.

    The concept of 'classification' has, similar to many other diseases, been found to be fundamental in the field of diabetic medicine. In the current study, we aimed at determining efficacy measures of a recently published plantar pressure based classification system. Technical efficacy of the classification system was investigated by applying a high resolution, pixel-level analysis on the normalized plantar pressure pedobarographic fields of the original experimental dataset consisting of 97 patients with diabetes and 33 persons without diabetes. Clinical efficacy was assessed by considering the occurence of foot ulcers at the plantar aspect of the forefoot in this dataset. Classification efficacy was assessed by determining the classification recognition rate as well as its sensitivity and specificity using cross-validation subsets of the experimental dataset together with a novel cohort of 12 patients with diabetes. Pixel-level comparison of the four groups associated to the classification system highlighted distinct regional differences. Retrospective analysis showed the occurence of eleven foot ulcers in the experimental dataset since their gait analysis. Eight out of the eleven ulcers developed in a region of the foot which had the highest forces. Overall classification recognition rate exceeded 90% for all cross-validation subsets. Sensitivity and specificity of the four groups associated to the classification system exceeded respectively the 0.7 and 0.8 level in all cross-validation subsets. The results of the current study support the use of the novel plantar pressure based classification system in diabetic foot medicine. It may particularly serve in communication, diagnosis and clinical decision making. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available Abstract Background Data comparing duloxetine with existing antidepressant treatments is limited. A comparison of duloxetine with fluoxetine has been performed but no comparison with venlafaxine, the other antidepressant in the same therapeutic class with a significant market share, has been undertaken. In the absence of relevant data to assess the place that duloxetine should occupy in the therapeutic arsenal, indirect comparisons are the most rigorous way to go. We conducted a systematic review of the efficacy of duloxetine, fluoxetine and venlafaxine versus placebo in the treatment of Major Depressive Disorder (MDD, and performed indirect comparisons through meta-regressions. Methods The bibliography of the Agency for Health Care Policy and Research and the CENTRAL, Medline, and Embase databases were interrogated using advanced search strategies based on a combination of text and index terms. The search focused on randomized placebo-controlled clinical trials involving adult patients treated for acute phase Major Depressive Disorder. All outcomes were derived to take account for varying placebo responses throughout studies. Primary outcome was treatment efficacy as measured by Hedge's g effect size. Secondary outcomes were response and dropout rates as measured by log odds ratios. Meta-regressions were run to indirectly compare the drugs. Sensitivity analysis, assessing the influence of individual studies over the results, and the influence of patients' characteristics were run. Results 22 studies involving fluoxetine, 9 involving duloxetine and 8 involving venlafaxine were selected. Using indirect comparison methodology, estimated effect sizes for efficacy compared with duloxetine were 0.11 [-0.14;0.36] for fluoxetine and 0.22 [0.06;0.38] for venlafaxine. Response log odds ratios were -0.21 [-0.44;0.03], 0.70 [0.26;1.14]. Dropout log odds ratios were -0.02 [-0.33;0.29], 0.21 [-0.13;0.55]. Sensitivity analyses showed that results were

    Commercial trainable hearing aids (HA) (i.e., devices that for a period are adjusted by the user in different acoustic environments and that subsequently with changing environments automatically adapt to the user's preferred settings), are readily available; however, little information exists about the efficacy of training a HA. The purpose of this study was to investigate the efficacy and reliability of training a HA in everyday environments. The participants were 26 hearing-impaired volunteers with a median age of 79 years and an average pure-tone average of 53 dB HL. Test devices were commercial, multimemory, prototype devices that enabled training of the compression characteristics in four frequency bands and in six sound classes. Participants wore the National Acoustic Laboratories nonlinear fitting procedure version 2 prescription for 3 weeks and trained the devices from the prescribed response for 3 weeks, before comparing their trained response with the prescription for 2 weeks. The devices were reset to the prescription, and 19 participants repeated the training and comparison trials. During the comparison trial, participants made daily diary ratings of their satisfaction with the programs, and a structured interview was completed at the end of the comparison trial. The participants displayed different needs for changing the prescription, with more daily adjustments leading to training across more sound classes. Unreliable observations were obtained from 8 participants after each of the test and retest comparison trials. Of the 10 participants who made sufficient changes to the prescription during the first trial, 80% preferred their trained response. The 8 "low trainers" reported no preference, and also reported lower overall satisfaction with the device. Fewer adjustments were made during the repeat trial, resulting in less training. Significant correlations between trained variations were seen for 63% of 19 participants. Of the 10 participants who

    Concerns about photodegradation products leaching from plastic bottle material into water during solar water disinfection (SODIS) are a major psychological barrier to increased uptake of SODIS. In this study, a comparison of SODIS efficacy using glass and plastic polyethylene terephalate (PET) bottles was carried out under strong real sunlight and overcast weather conditions at Makerere University in central Uganda. Both clear and turbid natural water samples from shallow wells and open dug wells, respectively, were used. Efficacy was determined from the inactivation of a wild strain of Escherichia coli in solar-exposed contaminated water in both glass and PET bottles. The studies reveal no significant difference in SODIS inactivation between glass and PET bottles (95% CI, p > 0.05), for all water samples under the different weather conditions except for clear water under overcast conditions where there was a small but significant difference (95% CI, p = 0.047) with less viable bacterial counts in PET bottles at two intermediate time points but not at the end of the exposure. The results demonstrate that SODIS efficacy in glass under tropical field conditions is comparable to PET plastic. SODIS users in these regions can choose either of reactors depending on availability and preference of the user.

    The treatment of postpartum depression with selective serotonin reuptake inhibitors (SSRIs) has been claimed to be both efficacious and well tolerated, but no recent systematic reviews have been conducted. A qualitative systematic review of randomized clinical trials on women with postpartum depression comparing SSRIs to placebo and/or other treatments was performed. A comprehensive literature search of online databases, the bibliographies of published articles and grey literature were conducted. Data on efficacy, acceptability and tolerability were extracted and the quality of the trials was assessed. Six randomised clinical trials, comprising 595 patients, met quality criteria for inclusion in the analysis. Cognitive-behavioural intervention, psychosocial community-based intervention, psychodynamic therapy, cognitive behavioural therapy, a second-generation tricyclic antidepressant and placebo were used as comparisons. All studies demonstrated higher response and remission rates among those treated with SSRIs and greater mean changes on depression scales, although findings were not always statistically significant. Dropout rates were high in three of the trials but similar among treatment and comparison groups. In general, SSRIs were well tolerated and trial quality was good. There are few trials, patients included in the trials were not representative of all patients with postpartum depression, dropout rates in three trials were high, and long-term efficacy and tolerability were assessed in only two trials. SSRIs appear to be efficacious and well tolerated in the treatment of postpartum depression, but the available evidence fails to demonstrate a clear superiority over other treatments. © 2013 Elsevier B.V.

    Naïve-indirect comparisons are comparisons between competing clinical interventions' evidence from separate (uncontrolled) trials. Direct comparisons are comparisons within randomised control trials (RCTs). The objective of this empirical study is to test the null-hypothesis that trends and performance differences inferred from naïve-indirect comparisons and from direct comparisons/RCTs regarding the failure rates of amalgam and direct high-viscosity glass-ionomer cement (HVGIC) restorations in permanent posterior teeth have similar direction and magnitude. A total of 896 citations were identified through systematic literature search. From these, ten and two uncontrolled clinical longitudinal studies for HVGIC and amalgam, respectively, were included for naïve-indirect comparison and could be matched with three out twenty RCTs. Summary effects sizes were computed as Odds ratios (OR; 95% Confidence intervals) and compared with those from RCTs. Trend directions were inferred from 95% Confidence interval overlaps and direction of point estimates; magnitudes of performance differences were inferred from the median point estimates (OR) with 25% and 75% percentile range, for both types of comparison. Mann-Whitney U test was applied to test for statistically significant differences between point estimates of both comparison types. Trends and performance differences inferred from naïve-indirect comparison based on evidence from uncontrolled clinical longitudinal studies and from direct comparisons based on RCT evidence are not the same. The distributions of the point estimates differed significantly for both comparison types (Mann-Whitney U  =  25, n(indirect)  =  26; n(direct)  =  8; p  =  0.0013, two-tailed). The null-hypothesis was rejected. Trends and performance differences inferred from either comparison between HVGIC and amalgam restorations failure rates in permanent posterior teeth are not the same. It is recommended that clinical practice

    The objective of this study was to evaluate the contraceptive efficacy and clinical performance of a Nestorone subdermal implant (NES) in the postpartum period. NES (n = 100) and Copper T intrauterine device (T-Cu; n = 100) acceptors initiated contraception at 8 weeks postpartum and were followed at monthly intervals during the first year and at 3-month intervals thereafter. Pregnancy rates, breastfeeding performance, infant growth, bleeding pattern, and side effects were assessed. Blood and milk NES concentration were measured. No pregnancy occurred in 2195 and 2145 woman-months of NES implant and T-Cu use, respectively. No effect of NES on lactation and infant growth and no serious adverse events were observed. Lactational amenorrhea was significantly longer in NES users (353 +/- 20 days) than in T-Cu users (201 +/- 11 days). More NES users (55.8%) experienced prolonged bleedings than did T-Cu users (36.2%). Concentrations of NES in breast milk ranged between 54-135 pmol/liter. The Nestorone implant is a highly effective contraceptive, safe for breastfed infants because the steroid is inactive by the oral route.

  3. Public Reporting of Primary Care Clinic Quality: Accounting for Sociodemographic Factors in Risk Adjustment and Performance Comparison.

    2018-01-03

    Performance measurement and public reporting are increasingly being used to compare clinic performance. Intended consequences include quality improvement, value-based payment, and consumer choice. Unintended consequences include reducing access for riskier patients and inappropriately labeling some clinics as poor performers, resulting in tampering with stable care processes. Two analytic steps are used to maximize intended and minimize unintended consequences. First, risk adjustment is used to reduce the impact of factors outside providers' control. Second, performance categorization is used to compare clinic performance using risk-adjusted measures. This paper examines the effects of methodological choices, such as risk adjusting for sociodemographic factors in risk adjustment and accounting for patients clustering by clinics in performance categorization, on clinic performance comparison for diabetes care, vascular care, asthma, and colorectal cancer screening. The population includes all patients with commercial and public insurance served by clinics in Minnesota. Although risk adjusting for sociodemographic factors has a significant effect on quality, it does not explain much of the variation in quality. In contrast, taking into account the nesting of patients within clinics in performance categorization has a substantial effect on performance comparison.

    Diabetes self-management education has an important role in diabetes management. The efficacy of education has been proven in several randomized trials. However, the status of diabetes education programs in real Korean clinical practice has not yet been evaluated in terms of patient compliance with the education prescription. We retrospectively analyzed clinical and laboratory data from all patients who were ordered to undergo diabetes education during 2009 at Samsung Medical Center, Seoul, Korea (n=2,291). After excluding ineligible subjects, 588 patients were included in the analysis. Among the 588 patients, 433 received education. The overall compliance rate was 73.6%, which was significantly higher in the subjects with a short duration or living in a rural area compared to those with a long duration (85.0% vs. 65.1%, respectively; Ppatients refuse to get education despite having a prescription from their physician. This refusal rate was higher in the patients with long-standing diabetes or in urban residence. Furthermore, education was more effective in patients with a short duration of diabetes in clinical practice.

    Full Text Available Introduction: Probiotic technology represents a breakthrough approach to maintaining oral health by utilizing natural beneficial bacteria commonly found in healthy mouths to provide a natural defense against those bacteria thought to be harmful to teeth and gums. However, data are still sparse on the probiotic action in the oral cavity. The review article on probiotics in children published by Twetman and Stecksen- Blicks in 2008 showed only one study of dental interest on probiotics in children. Aim and Objectives: The present study evaluated clinically the efficacy of a probiotic and chlorhexidine mouth rinses on plaque and gingival accumulation in children. The trial design is a double-blind parallel group, 14 days comparative study between a probiotic mouth rinse and a chlorhexidine mouth rinse, which included 45 healthy children in the age group of 6-8 years. Results: The Probiotic and Chlorhexidine groups had less plaque accumulations compared with the Control group at the end of 14 years (P < 0.001 and P < 0.001, respectively. But, unlike the plaque score, there was a significant difference in the Gingival Index between the Probiotic and the Chlorhexidine groups (P = 0.009, Probiotic group being better than the Chlorhexidine group (mean = 0.2300 and 0.6805, respectively. Conclusion: The Probiotic mouth rinse was found effective in reducing plaque accumulation and gingival inflammation. Therefore, probiotic mouth rinse obviously has a potential therapeutic value and further long-term study is recommended to determine its efficacy.

    The aim of this study was to compare the performance of three search methods in the retrieval of relevant clinical trials from PubMed to answer specific clinical questions. Included studies of a sample of 100 Cochrane reviews which recorded in PubMed were considered as the reference standard. The search queries were formulated based on the systematic review titles. Precision, recall and number of retrieved records for limiting the results to clinical trial publication type, and using sensitive and specific clinical queries filters were compared. The number of keywords, presence of specific names of intervention and syndrome in the search keywords were used in a model to predict the recalls and precisions. The Clinical queries-sensitive search strategy retrieved the largest number of records (33) and had the highest recall (41.6%) and lowest precision (4.8%). The presence of specific intervention name was the only significant predictor of all recalls and precisions (P = 0.016). The recall and precision of combination of simple clinical search queries and methodological search filters to find clinical trials in various subjects were considerably low. The limit field strategy yielded in higher precision and fewer retrieved records and approximately similar recall, compared with the clinical queries-sensitive strategy. Presence of specific intervention name in the search keywords increased both recall and precision. © 2010 John Wiley & Sons Ltd.

    Although the Dedicated Education Unit (DEU) has shown initial promise related to satisfaction with the teaching/learning environment, few studies have examined student outcomes related to the use of the DEU as a clinical education model beyond student satisfaction. The purpose of this quantitative, quasi-experimental study was to compare student outcomes from the traditional clinical education (TCE) model with those from the DEU model. Participants were students enrolled in a four-year baccalaureate program in nursing (n = 193) who had clinical education activities in one of three clinical agencies. Participants were assigned to either the DEU or a TCE model. Pre-clinical and post-clinical self-efficacy scores were measured for each group using an adapted Generalized Self-Efficacy Scale (Schwarzer and Jerusalem, 1995). Both groups experienced a significant increase in self-efficacy scores post clinical education. The increase in self-efficacy for the DEU students was significantly greater than the increase in self-efficacy for the traditional students. Self-efficacy is considered an important outcome of nursing education because high self-efficacy has been linked to making an easier transition from student to nursing professional. This study supports the quality of the DEU as a clinical education model by examining student self-efficacy outcomes. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Objective: To compare the relative efficacy of infliximab, adalimumab and golimumab through adjusted indirect treatment comparisons (ITCs. Methods: An exhaustive search was performed until October 2013. Databases consulted were MEDLINE, EMBASE, the Cochrane Library, the Centre for Reviews and Dissemination and the Web of Science. Randomized control trials (RCTs comparing the efficacy of infliximab, adalimumab or golimumab versus placebo, in terms of clinical remission, clinical response and mucosal healing, were included. In the case that more than one RCT fulfilled the inclusion criteria for the same drug, a metanalysis was undertaken using a fixed effects model. ITCs were carried out using the method proposed by Bucher et al. Results: 6 RCTs published in 5 papers were included: 2 for infliximab (ACT 1 and ACT 2, 2 for adalimumab (ULTRA 1 y ULTRA 2 and 2 for golimumab (PURSUIT-SC y PURSUIT-M.In these RTCs, each biological agent was superior in efficacy to placebo. The results of the adjusted ITC are the following. In relation to the clinical remission, in the induction and maintenance period, there are no statistically significant differences between the three anti-TNF drugs. In relation to the clinical response and mucosal healing, in the induction period, there are statistically significant differences between infliximab and adalimumab. Conclusion: In view of the results obtained, infliximab, adalimumab and golimumab appear to be similarly effective therapeutic alternatives. Therefore, other considerations such as safety, tolerance and cost-effectiveness should be taken into account in order to select the most appropriate treatment

    Background A double-blind placebo-controlled trial was conducted in order to evaluate the efficacy of alpha lipoic acid (ALA) and determine the statistical significance of the outcome variables. Burning mouth syndrome (BMS) is defined as an oral burning sensation in the absence of clinical signs which could justify the syndrome. Recent studies suggest the existence of neurological factors as a possible cause of the disease. Material and Methods 60 patients with BMS, in two groups: case group with 600 mg/day and placebo as control group; with follow up of 2 months. Results 64% of ALA patients reported some level of improvement, with a level of maintenance of 68.75% one month after treatment. 27.6% of the placebo group also demonstrated some reduction in BMS symptoms. Conclusions Long-term evolution and the intensity of symptoms are variables that reduce the probability of improvement with ALA treatment. Key words: Burning mouth syndrome, neuropathy, alpha lipoic acid. PMID:26034927

    Streptococcus mutans is the most common organism causing dental caries. Various chemotherapeutic agents are available that help in treating the bacteria, with each having their own merits and demerits. Recent research has shown that coconut oil has anti-inflammatory and antimicrobial action. Therefore, the present was conducted to determine the antibacterial efficacy of coconut oil and to compare it with chlorhexidine. A total of fifty female children aged 8-12 years were included in the study. Twenty five children were randomly distributed to each group, i.e., the study group (coconut oil) and the control group (chlorhexidine). The participants were asked to routinely perform oil swishing with coconut oil and chlorhexidine and rinse every day in the morning after brushing for 2-3 minutes. S. mutans in saliva and plaque were determined using a chairside method, i.e., the Dentocult SM Strip Mutans test. Patients were instructed to continue oil swishing for 30 days. S. mutans . counts in plaque and saliva on day 1, day 15, and day 30 were recorded and the results were compared using Wilcoxon matched pairs signed ranks test. The results showed that there is a statistically significant decrease in S. mutans . count from coconut oil as well as chlorhexidine group from baseline to 30 days. The study also showed that in comparison of coconut oil and chlorhexidine there is no statistically significant change regarding the antibacterial efficacy. Coconut oil is as effective as chlorhexidine in the reduction of S. mutans .

    Diabetes mellitus is a widely spread chronic disease with growing incidence worldwide, and diabetic foot ulcer is one of the most serious complications of diabetes. Cellular therapy has shown promise in the management of diabetic foot ulcer in many preclinical experiments and clinical researches. Here, we performed a meta-analysis to evaluate the efficacy and safety of cellular therapy in the management of diabetic foot ulcer. We systematically searched PubMed, MEDLINE, EMBASE, and Cochrane Library databases from inception to May 2017 for randomized controlled trials assessing the efficacy of cellular therapy in diabetic foot ulcer, and a meta-analysis was conducted. A total of 6 randomized controlled clinical trials involving 241 individuals were included in this meta-analysis. The results suggested that cellular therapy could help accelerating the healing of diabetic foot ulcer, presented as higher ankle-brachial index (mean difference = 0.17, 95% confidence interval [CI] = 0.11 to 0.23), higher transcutaneous oxygen pressure (standardized mean difference [SMD] = 1.43; 95% CI, 1.09- to 1.78), higher ulcer healing rate (relative risk [RR] = 1.78; 95% CI, 1.41 to 2.25), higher amputation-free survival (RR = 1.25; 95% CI, 1.11 to 1.40), and lower scale of pain (SMD = -1.69; 95% CI, -2.05 to -1.33). Furthermore, cellular therapy seemed to be safe, with no serious complications and low risk of short-term slight complications. Cellular therapy could accelerate the rate of diabetic foot ulcer healing and may be more efficient than standard therapy for diabetic foot treatment.

    Leading cause of disability worldwide, depression is the most prevalent mental disorder with growing societal costs. As mental health services demand often outweighs provision, accessible treatment options are needed. Our systematic review and meta-analysis evaluated the clinical efficacy and economic evidence for the use of online cognitive behavioral therapy (oCBT) as an accessible treatment solution for depression. Areas covered: Electronic databases were searched for controlled trials published between 2006 and 2016. Of the reviewed 3,324 studies, 29 met the criteria for inclusion in the efficacy meta-analysis. The systematic review identified five oCBT economic evaluations. Therapist-supported oCBT was equivalent to face-to-face CBT at improving depressive symptoms and superior to treatment-as-usual, waitlist control, and attention control. Depression severity, number of sessions, or support did not affect efficacy. From a healthcare provider perspective, oCBT tended to show greater costs with greater benefits in the short term, relative to comparator treatments. Expert commentary: Although efficacious, further economic evidence is required to support the provision of oCBT as a cost-effective treatment for depression. Economic evaluations that incorporate a societal perspective will better account for direct and indirect treatment costs. Nevertheless, oCBT shows promise of effectively improving depressive symptoms, considering limited mental healthcare resources.

    To clinically and radiographically evaluate the reparative dentin formation in indirect pulp treatment (IPT) using mineral trioxide aggregate (MTA) and light cured calcium silicate (TheraCal) in primary molars over a period of 6 months. A clinical trial on IPT on 43 primary molars in 21 patients between the age of 4-7 years, divided into two groups: 22 teeth in MTA group and 21 in TheraCal group. Measurement of the variation in dentin thickness was done on the digitalized radiograph at baseline, 3 months and 6 months using CorelDRAW X3 software. Statistical analysis using an independent t -test for intragroup and intergroup comparison showed a significant increase in dentin thickness in both the MTA and TheraCal group (intragroup comparison [ P 0.05). Clinically and radiographically, both MTA and TheraCal are good IPT materials. The better handling characteristics and comparable reparative dentin-forming ability of TheraCal make this material an alternative to MTA in pediatric restorative procedures.

    The aim of this systematic review was to evaluate the efficacy of amino acid-based formulas (AAF) in patients with cow's milk allergy (CMA). Studies were identified using electronic databases and bibliography searches. Subjects eligible for inclusion were patients of any age with CMA or symptoms suggestive of it. Comparisons of interest were AAF vs. extensively hydrolysed formula (eHF), AAF vs. soy-based formula (SF) and AAF vs. cow's milk or cow's milk-based formula. Outcomes of interest were gastrointestinal (GI), dermatological, respiratory and behavioural symptoms as well as growth. A total of 20 studies [three head-to-head randomized controlled trials (RCTs), three cross-over challenge RCTs, seven clinical trials (CTs) and seven case reports (CRs)] were included in the review. In infants with confirmed or suspected CMA, the use of an AAF was shown to be safe and efficacious. Findings from RCT comparisons of AAF with eHF showed that both formulas are equally efficacious at relieving the symptoms of CMA in confirmed or suspected cases. However, infants in specific subgroups (e.g. non-IgE mediated food-induced gastro-enterocolitis-proctitis syndromes with failure to thrive, severe atopic eczema, or with symptoms during exclusive breastfeeding) were more likely overall to benefit from AAF, as intolerance to eHF may occur. In such cases, symptoms persisting despite eHF feeding usually remit on AAF, and catch-up growth may be seen. Meta-analysis of the findings was not possible due to lack of homogenous reporting of outcomes in the original trials. This systematic review shows clinical benefit from use of AAF in both symptoms and growth in infants and children with CMA who fail to tolerate eHF. Further studies are required to determine the relative medical or economic value of initial treatment with AAF in infants at high risk of eHF intolerance.

    Full Text Available Background: Oocyte vitrification is widely used throughout the world, but its clinical efficacy is inconsistent and depends on the vitrification media. This study compared the developmental potential and clinical results of in vivo matured oocytes cryopreserved with different vitrification media. Methods: This retrospective study involved vitrified-warmed oocytes at one in vitro fertilization laboratory. Vitrification media kits comprised the MC kit (ethylene glycol [EG] plus 1,2-propanediol [PROH], the KT kit (EG plus dimethyl sulphoxide [DMSO], and the Modified kit (EG plus DMSO and PROH kit. Rates of oocyte survival and subsequent developmental potential were recorded and analyzed. The t-test and the Chi-square test were used to evaluate each method′s efficacy. Results: Oocyte survival rate was significantly higher for the Modified kit (92.0% than for the MC kit (88.2% (P 0.05. The high-quality embryo rate per warmed oocyte was significantly higher (23.4% in the Modified kit group than in the other groups (P 0.05. Conclusions: Modified vitrification media are efficient for oocyte vitrification and, with further verification, may be able to replace commercially available media in future clinical applications.

    Full Text Available [english] Dental plaque critically affects the etiology of caries, periodontitis and periimplantitis. The mechanical removal of plaque can only be performed partially due to limited accessibility. Therefore, plaque still represents one of the major therapeutic challenges. Even though antiseptic mouth rinses reduce the extent of biofilm temporarily, plaque removal remains incomplete and continuous usage can even result in side effects. Here we tested argon plasma produced by kinpen09 as one option to inactivate microorganisms and to eliminate plaque. biofilms cultivated in either the European Biofilm Reactor (EUREBI or in 24 well plates were treated with argon plasma. In both test systems a homogeneous, good analyzable and stable biofilm was produced on the surface of titan plates within 72 h (>6,9 log CFU/ml. Despite the significantly more powerful biofilm production in EUREBI, the difference of 0.4 log CFU/ml between EUREBI and the 24 well plates was practically not relevant. For that reason both test models were equally qualified for the analysis of efficacy of cold atmospheric pressure plasma. We demonstrate a significant reduction of the biofilm compared to the control in both test models. After plasma application of 180 s the biofilm produced in EUREBI or in 24 well plates was decreased by 0.6 log CFU/ml or 0.5 log CFU/ml, respectively. In comparison to recently published studies analyzing the efficacy of kinpen09, produces a hardly removable biofilm. Future investigations using reduced distances between plasma source and biofilm, various compositions of plasma and alternative plasma sources will contribute to further optimization of the efficacy against biofilms.

    The aim of the present study was to evaluate the predation efficacy of Bdellovibrio bacteriovorus on multidrug-resistant (MDR) or extensive drug resistant (XDR) gram-negative pathogens and their corresponding biofilms. In this study, we examined the ability of B. bacteriovorus to prey on MDR and XDR gram-negative clinical bacteria, including Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Acinetobacter baumannii. Results showed that B. bacteriovorus was able to prey on all planktonic cultures, among which the most efficient predation was observed for drug-resistant E. coli, with a 3.11 log10 reduction in viability. Furthermore, B. bacteriovorus demonstrated promising efficacy in preventing biofilm formation and dispersing the established biofilm. Reductions in biofilm formation of E. coli, K. pneumoniae, P. aeruginosa, and A. baumannii co-cultured with B. bacteriovorus were 65.2%, 37.1%, 44.7%, and 36.8%, respectively. Meanwhile, the established biofilms of E. coli, K. pneumoniae, P. aeruginosa, and A. baumannii were significantly reduced by 83.4%, 81.8%, 83.1%, and 79.9%, respectively. A visual analysis supported by scanning electron microscopy demonstrated the role of B. bacteriovorus in removing the established biofilms. This study highlights the potential use of B. bacteriovorus as a biological control agent with the capability to prey on MDR/XDR gram-negative pathogens and eradicate biofilms.

    It remains uncertain whether bipolar disorder (BPD) patients in randomized-controlled trials (RCTs) are sufficiently representative of clinically encountered patients as to guide clinical-therapeutic practice. We complied inclusion/exclusion criteria by frequency from reports of 21 RCTs for mania, and applied them in a pilot study of patients hospitalized for DSM-IV BPD manic/mixed states to compare characteristics and clinical responses of patients who did versus did not meet exclusion criteria. From 27 initially identified inclusion/exclusion criteria ranked by citation frequency, we derived six inclusion, and 10 non-redundant-exclusion factors. Of 67 consecutive patients meeting inclusion criteria, 15 (22.4%) potential "research subjects" met all 10 exclusion criteria. The remaining 52 "clinical patients" differed markedly on exclusion criteria, including more psychiatric co-morbidity, substance abuse, involuntary hospitalization, and suicide attempts or violence, but were otherwise similar. In both groups responses to clinically determined inpatient treatments were similar, including improvement in mania ratings. Based on applying reported inclusion/exclusion criteria for RCTs to a pilot sample of hospitalized-manic patients, those likely to be included in modern RCTs were similar to patients who would be excluded, most notably in short-term antimanic-treatment responses. The findings encourage further comparisons of subjects included/excluded from RCTs to test potential clinical generalizability of research findings. The pilot study is limited in numbers and exposure times with which to test for the minor differences between "research subjects" and "clinical patients." (c) 2008 John Wiley & Sons, Ltd.

    Monoamine oxidase type B (MAO-B) inhibitors, such as selegiline and rasagiline, can be used as monotherapy or adjuvant therapy to levodopa in Parkinson's disease (PD). Data on long-term efficacy of MAO-B inhibitors are limited with no head-to-head comparison available to date. The aim of this case-control retrospective study was to analyze data from patients with PD attending the Parkinson Institute (Milan, Italy) over a 6-year period (2009-2015) and compare the effects of selegiline and rasagiline on levodopa treatment outcomes. Patients with PD treated with either selegiline (n = 85) or rasagiline (n = 85) for 3 years as well as a control group of patients (N = 170) who have never received MAO-B inhibitors, were matched for gender, disease duration (±1 year) and age (±1 year) at baseline assessment (ratio 1:1:2). The Unified PD Rating Scale and the Hoehn-Yahr staging system were used for clinical comparisons. At baseline, mean PD duration was 6.5 years and clinical features were comparable across all three groups. After a mean follow-up of approximately 37 months, no differences in clinical progression of motor and non-motor symptoms were observed between the three groups. However, MAO-B inhibitor use was associated with ~2-fold lower change in daily dose of levodopa (p rasagiline. Long-term use of MAO-B inhibitors resulted in a significant reduction in levodopa requirements and a lower frequency of dyskinesias in patients with PD. Selegiline and rasagiline had equal efficacy in controlling motor symptoms in PD patients on optimized therapy.

    Full Text Available Introduction : Patient-prosthesis mismatch (PPM is relatively frequent after surgical aortic valve replacement (SAVR and negatively impacts prognosis. Aim : We sought to determine the frequency and clinical effects of PPM after transcatheter aortic valve implantation (TAVI. Material and methods : Overall, 238 patients who underwent TAVI were screened. Moderate PPM was defined as indexed effective orifice area (EOAi between 0.65 and 0.85 cm2/m2, and severe PPM as < 0.65 cm2/m2. All-cause mortality and the Valve Academic Research Consortium 2 (VARC-2 defined composite of clinical efficacy at 1 year were the primary endpoints. Results : Finally, 201 patients were included (mean age: 79.6 ±7.4 years, 52% females. The femoral artery served as the delivery route in 79% and most of the prostheses were self-expanding (68%. Any PPM was present in 48 (24% subjects, and only 7 (3.5% had severe PPM. Body surface area (BSA independently predicted any PPM (OR = 16.9, p 20 mm Hg. Conclusions : Severe PPM after TAVI is rare, can be predicted by larger BSA and does not seem to affect mid-term mortality or composite clinical outcome. Larger studies are needed to find different independent predictors of PPM and elucidate its impact in terms of device durability and long-term clinical efficacy.

    To compare the clinical efficacy and complications of limited internal fixation combined with external fixation (LIFEF) and open reduction and internal fixation (ORIF) in the treatment of Pilon fracture. We searched databases including Pubmed, Embase, Web of science, Cochrane Library and China Biology Medicine disc for the studies comparing clinical efficacy and complications of LIFEF and ORIF in the treatment of Pilon fracture. The clinical efficacy was evaluated by the rate of nonunion, malunion/delayed union and the excellent/good rate assessed by Mazur ankle score. The complications including infections and arthritis symptoms after surgery were also investigated. Nine trials including 498 pilon fractures of 494 patients were identified. The meta-analysis found no significant differences in nonunion rate (RR = 1.60, 95% CI: 0.66 to 3.86, p = 0.30), and the excellent/good rate (RR = 0.95, 95% CI: 0.86 to 1.04, p = 0.28) between LIFEF group and ORIF group. For assessment of infections, there were significant differences in the rate of deep infection (RR = 2.18, 95% CI: 1.34 to 3.55, p = 0.002), and the rate of arthritis (RR = 1.26, 95% CI: 1.03 to 1.53, p = 0.02) between LIFEF group and ORIF group. LIFEF has similar effect as ORIF in the treatment of pilon fractures, however, LIFEF group has significantly higher risk of complications than ORIF group does. So LIFEF is not recommended in the treatment of pilon fracture. Copyright © 2017 Daping Hospital and the Research Institute of Surgery of the Third Military Medical University.

    Full Text Available There are an estimated 200,000 to 400,000 cases of visceral leishmaniasis (VL annually. A variety of factors are taken into account when considering the best therapeutic options to cure a patient and reduce the risk of resistance, including geographical area, malnourishment and HIV coinfection. Pooled analyses combine data from many studies to answer specific scientific questions that cannot be answered with individual studies alone. However, the heterogeneity of study design, data collection, and analysis often makes direct comparison difficult. Individual Participant Data (IPD files can be standardised and analysed, allowing detailed analysis of this merged larger pool, but only a small fraction of systematic reviews and meta-analyses currently employ pooled analysis of IPD. We conducted a systematic literature review to identify published studies and studies reported in clinical trial registries to assess the feasibility of developing a VL data sharing platform to facilitate an IPD-based analysis of clinical trial data. Studies conducted between 1983 to 2015 that reported treatment outcome were eligible.From the 2,271 documents screened, 145 published VL clinical trials were identified, with data from 26,986 patients. Methodologies varied for diagnosis and treatment outcomes, but overall the volume of data potentially available on different drugs and dose regimens identified hundreds or possibly thousands of patients per arm suitable for IPD pooled meta-analyses.A VL data sharing platform would provide an opportunity to maximise scientific use of available data to enable assessment of treatment efficacy, contribute to evidence-based clinical management and guide optimal prospective data collection.

    Full Text Available Background: Recently, higher efficacy of the combination of long-acting beta2-adrenoceptor agonist and inhaled corticosteroids on controlling asthma symptoms has been hypothesized. This study aimed to examine the clinical effects of the combination of Budesonide with formoterol (Symbicort and Budesonide (Pulmicort alone in persistent asthma. Materials and Methods: In a randomized double-blinded clinical trial, 76 patients with definite diagnosis of moderate-to-severe asthma were randomized to receive Pulmicort 180 mcg/inhalation two puffs twice daily, or receive Symbicort 80/4.5 mg/inhalation two puffs twice daily, or receive Symbicort 160/4.5 mg/inhalation two puffs twice daily for 3 months. All participants were initially evaluated by spirometry for assessing respiratory parameters and also the level of asthma control was assessed by Asthma Control Test (ACT. Results: More significant improvement in spirometry parameters, including forced expiratory volume in 1 second (FEV1, forced vital capacity (FVC, FEV1/FVC ratio, as well as in peak expiratory flow (PEF in both groups of Symbicort with the regimens 80/4.5 mg/inhalation or 160/4.5 mg/inhalation 2 puffs twice daily compared with Pulmicort group, ACT score was significantly improved in Symbicort group with the regimens 160/4.5 mg/inhalation compared with both Symbicort groups with lower dosage and Pulmicort group . Response to treatment in PEF parameter and also in ACT level was significantly more in those who received Symbicort with the regimens 160/4.5 mg/inhalation compared with other two interventional groups adjusted for gender and age. Conclusion: Symbicort with the regimens 160/4.5 mg/inhalation has higher efficacy in reducing asthma symptom and improving its control compared with low doses of this drug and with Pulmicort.

    Melphalan followed by hematopoietic stem-cell transplantation (HSCT) is the standard treatment for multiple myeloma and other hematopoietic neoplasms. However, high doses of melphalan cause severe oral mucositis (OM). The objective was to verify the efficacy of cryotherapy plus laser therapy on reduction of OM severity. HSCT patients undergoing melphalan chemotherapy (n = 71) were randomly divided into two groups according to OM treatment: oral cryotherapy performed with ice chips for 1 h 35 min followed by low-level laser therapy (InGaAIP, 660 nm, 40 mW, 6 J/cm(2) ) (n = 54) and laser therapy alone with the same protocol (n = 17). A control group (n = 33) was composed of HSCT patients treated with melphalan who received no specific treatment for OM. OM scores and clinical information were collected from D0 to D + 11. The cryotherapy/laser therapy group showed the lowest OM scores (maximum Grade I) and the lowest mean number of days (8 days) with OM in comparison with the other groups (p cryotherapy with laser therapy was effective in reducing OM severity in HSCT patients who underwent melphalan conditioning.

    Advancement in technology in terms of design and building materials has made Total Knee Replacement (TKR) a highly effective, safe, and predictable orthopedic procedure. To review the clinical outcomes for efficacy and performance of Freedom Total Knee System for the management of Osteoarthritis (OA), at a minimum of three years follow up. For this retrospective, post-marketing study, clinical data of patients treated with Freedom Total Knee System was retrieved from the clinical records after approval from the Institutional Ethics Committee . All the patients above the age of 18 years who completed at least three years after TKR were observed for the study purpose. Patients treated for OA were included while the patients who received the implant for treatment of rheumatoid arthritis and traumatic injury were excluded. Factors such as aseptic loosening, implant failure, and need for revision surgery were observed to evaluate implant performance. Cases were recruited for clinical assessment of primary efficacy endpoint in terms of post-surgery maximun range of motion. Secondary efficacy endpoint was to determine the clinical and social quality of life as per the American Knee Society Score (AKSS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain and stiffness scores. A total of 158 patients who had 191 TKR were observed for performance. The mean age of the patients was 67.67 years; mean BMI was 28.97±3.33, and the group comprised of 43% men and 57% women. Telephonic follow up at three years of 158 patients identified that none of them required revision surgery or had aseptic loosening suggesting excellent performance. Final clinical follow up at three years was available for only 35 patients (41 knee implants). The range of motion significantly improved from preoperative 104°±5.67° (range, 85°-119°) to 119.8°±11.05° (98°-123°) at follow-up (ppain, and improved functionality.

    Many patients fulfill criteria for both posttraumatic stress disorder (PTSD) and major depressive disorder (MDD). Electroconvulsive therapy (ECT) is generally acknowledged to be the most-effective treatment for refractory MDD. This study investigated the efficacy of ECT on long-term clinical outcome of comorbid PTSD and MDD. This retrospective nested matched case-control study is inclusive of 22,164 subjects [3,485 with comorbid MDD and PTSD (92 with ECT and 3,393 without ECT) and 18,679 without MDD and PTSD]. Using the clinical global impression scale (CGI) to assess efficacy, more-robust improvement of PTSD and MDD symptoms was observed with ECT (90%), compared to antidepressant-treatment alone(50%) (P = 0.001). During the median of 8 years of follow-up, the death-rate was 8% in subjects without PTSD and MDD, 9.7% in PTSD and MDD treated with ECT and 18% in PTSD and MDD without ECT (P 0.05). The relative risk of suicidality, all-cause, and cardiovascular mortality was reduced 64, 65, and 46% in MDD and PTSD patients treated with ECT, compared to those without ECT (P < 0.05). ECT is associated with a significant reduction of symptoms of PTSD and MDD, as well as reduction in risk of suicidality, cardiovascular, and all-cause mortality in MDD and PTSD, an effect more robust than antidepressant-therapy alone. © 2015 Wiley Periodicals, Inc.

    This clinical trial was conducted to evaluate the efficacy and safety of Palonosetron in preventing chemotherapy-induced vomiting (CIV) among the Chinese cancer patients. Two hundred and forty patients were scheduled to be enrolled and randomized to receive a single intravenous dose of palonosetron 0.25 mg, or granisetron 3 mg, 30 min before receiving highly emetogenic chemotherapy. The primary efficacy endpoint was the complete response (CR) rate for acute CIV (during the 0-24-h interval after chemotherapy). Secondary endpoints included the CR rates for delayed CIV (more than 24 h after chemotherapy). Two hundred and eight patients were accrued and received study medication. CR rates for acute CIV were 82.69% for palonosetron and 72.12% for granisetron, which demonstrated that palonosetron was not inferior to granisetron in preventing acute CIV. Comparisons of CR rates for delayed CIV yielded no statistical difference between palonosetron and granisetron groups and did not reveal non-inferiority of palonosetron to granisetron. Adverse events were mostly mild to moderate, with quite low rates among the two groups. A single dose (0.25 mg) of palonosetron is not inferior to a single dose (3 mg) of granisetron in preventing CIV and possesses an acceptable safety profile in the Chinese population.

    Arctigenin (AR) and its glycoside, arctiin, are two major active ingredients of Arctium lappa L (A lappa), a popular medicinal herb and health supplement frequently used in Asia. In the past several decades, bioactive components from A lappa have attracted the attention of researchers due to their promising therapeutic effects. In the current article, we aimed to provide an overview of the pharmacology of AR and arctiin, focusing on their anti-inflammatory effects, pharmacokinetics properties and clinical efficacies. Compared to acrtiin, AR was reported as the most potent bioactive component of A lappa in the majority of studies. AR exhibits potent anti-inflammatory activities by inhibiting inducible nitric oxide synthase (iNOS) via modulation of several cytokines. Due to its potent anti-inflammatory effects, AR may serve as a potential therapeutic compound against both acute inflammation and various chronic diseases. However, pharmacokinetic studies demonstrated the extensive glucuronidation and hydrolysis of AR in liver, intestine and plasma, which might hinder its in vivo and clinical efficacy after oral administration. Based on the reviewed pharmacological and pharmacokinetic characteristics of AR, further pharmacokinetic and pharmacodynamic studies of AR via alternative administration routes are suggested to promote its ability to serve as a therapeutic agent as well as an ideal bioactive marker for A lappa.

    Lipoinjection is a promising treatment, but its efficacy in recontouring facial lipoatrophy remains to be established. The objective was to evaluate the efficacy and adverse effects of lipoinjection and supplementation of adipose-derived stem/stromal cells (ASCs) to adipose grafts. To overcome drawbacks of autologous lipoinjection, we have developed a novel strategy called cell-assisted lipotransfer (CAL). In CAL, stromal vascular fraction containing ASCs was freshly isolated from half of an aspirated fat sample and attached to the other half of aspirated fat sample with the fat acting as a scaffold. This process converts relatively ASC-poor aspirated fat into ASC-rich fat. We performed conventional lipoinjection (non-CAL; n=3) or CAL (n=3) on six patients with facial lipoatrophy due to lupus profundus or Parry-Romberg syndrome. All patients obtained improvement in facial contour, but the CAL group had a better clinical improvement score than did the non-CAL patients, although the difference did not reach statistical significance (p=.11). Adipose necrosis was found in one non-CAL case who took perioperative oral corticosteroids. Our results suggest that CAL is both effective and safe and potentially superior to conventional lipoinjection for facial recontouring. The authors have indicated no significant interest with commercial supporters.

    Brain arteriovenous malformations (BAVMs) are associated with high morbidity and mortality. The treatment of BAVM remains controversial. Microinvasive treatment, including endovascular therapy and gamma knife surgery, has been the first choice in many conditions. However, the overall clinical outcome of microinvasive treatment remains unknown and a prospective trial is needed. This is a prospective, non-randomized, and multicenter observational registry clinical trial to evaluate the safety and efficacy of microinvasive treatment for BAVMs. The study will require up to 400 patients in approximately 12 or more centers in China, followed for 2 years. Main subjects of this study are BAVM patients underwent endovascular therapy and/or gamma knife surgery. The trial will not affect the choice of treatment modality. The primary outcomes are perioperative complications (safety), and postoperative hemorrhage incidence rate and complete occlusion rate (efficacy). Secondary outcomes are elimination of hemorrhage risk factors (coexisting aneurysms and arteriovenous fistula), volume reduction and remission of symptoms. Safety and efficacy of endovascular therapy, gamma knife surgery, and various combination modes of the two modalities will be compared. Operative complications and outcomes at pretreatment, post-treatment, at discharge and at 3 months, 6 months and 2 years follow-up intervals will be analyzed using the modified Rankin Scale (mRS). The most confusion on BAVM treatment is whether to choose interventional therapy or medical therapy, and the choice of interventional therapy modes. This study will provide evidence for evaluating the safety and efficacy of microinvasive treatment in China, to characterize the microinvasive treatment strategy for BAVMs.

    Various treatments of osteoarthritis (OA) have been described, including use of nutraceuticals. To review systematically the literature about the effects of nutraceuticals on clinical signs of pain or abnormal locomotion in horses, dogs, and cats, and to discuss methodological aspects of trials and systematic reviews. A systematic search of controlled trials evaluating the impact of nutraceuticals on OA in horses, dogs, and cats was performed, using Medline, CAB Abstracts, and Google Scholar. Scientific evidence was evaluated by means of criteria proposed by the Food and Drug Administration (FDA), and a scoring system adapted from both the CONsolidated Standards of Reporting Trials (CONSORT) statement and recommendations for assessing trials by the Center of Evidence Based Medicine of Oxford. Twenty-two papers were selected and reviewed, with 5 studies performed in horses, 16 in dogs, and 1 in cats. The strength of evidence was low for all nutraceuticals except for omega-3 fatty acid in dogs. There were limited numbers of rigorous randomized controlled trials and of participants in clinical trials. The evidence of efficacy of nutraceuticals is poor, with the exception of diets supplemented with omega-3 fatty acids in dogs. Greater access to systematic reviews must be part of the objectives of the veterinary science in the future. Their reporting would be improved by internationally agreed-upon criteria for standards and guidelines. Copyright © 2012 by the American College of Veterinary Internal Medicine.

    Full Text Available Matthias W Riepe Mental Health and Geriatric Psychiatry, Psychiatry II, Ulm University, Ulm, Germany Abstract: Little is known about symptom preferences of clinical psychiatrists in the treatment of geriatric depression and preferences for avoiding adverse drug effects. Participants (board-certified psychiatrists were recruited prior to a lecture on geriatric depression during a continuing education program. An analytic hierarchy process was performed and participants were asked for pairwise comparison of criteria guiding them in appraising therapeutic efficacy, and in avoiding toxicity and adverse events. Of the 61 participants from the continuing education program, 42 (69% returned their data sheet. Avoidance of cardiotoxicity was regarded as more important than avoidance of hepatotoxicity or hematotoxicity. Concerning adverse events, highest preference was given to avoidance of falls and drug interactions, followed by avoidance of sedation, weight change, and impairment of sexual function. The most important preferences for appraisal of therapeutic efficacy were suicidality over ability to concentrate and sleep. Clinical psychiatrists have a hierarchy of preferences for treatment goals and avoidance of adverse events and toxicity. This raises the question for future research whether these preferences cause differences in prescription patterns in clinical practice even though a multitude of antidepressants are similarly effective when judged with instruments used in clinical trials. Keywords: depressive disorder, symptoms, analytic hierarchy process, toxicity, adverse events, symptoms

    Primary maternity care services are globally provided according to various organisational models. Two models are common in Finland: a maternity health clinic and an integrated maternity and child health clinic. The aim of this study was to clarify whether there is a relation between the organisational model of the maternity health clinics and the utilisation of maternity care services, and certain maternal and perinatal health outcomes. A comparative, register-based cross-sectional design was used. The data of women (N = 2741) who had given birth in the Turku University Hospital area between 1 January 2009 and 31 December 2009 were collected from the Finnish Medical Birth Register. Comparisons were made between the women who were clients of the maternity health clinics and integrated maternity and child health clinics. There were no clinically significant differences between the clients of maternity health clinics and integrated maternity and child health clinics regarding the utilisation of maternity care services or the explored health outcomes. The organisational model of the maternity health clinic does not impact the utilisation of maternity care services or maternal and perinatal health outcomes. Primary maternity care could be provided effectively when integrated with child health services.

    Full Text Available No prospective head-to-head trials comparing the fracture efficacy of the currently marketed weekly and monthly bisphosphonates have been conducted. Due to the large sample size such studies would require to reliably detect differences in fracture risk and the associated high costs, they are considered to be impractical. Whilst providing the highest level of evidence, clinical trials also have inherent limitations. Patients are selected by a number of criteria and therefore usually do not represent the normal patient population. Also due to a protocol, normal clinical practice is usually not reflected. In contrast, database studies allow the assessment of treatments in normal clinical practice. Whilst observational studies have limitations owing to more confounding variables, they do have an important place in evidence-based medicine (especially in the absence of prospective clinical trials, and if well-designed can give some indications regarding the comparative efficacy of osteoporosis therapies in real-world clinical practice.

    Amyotrophic lateral sclerosis (ALS) is a progressive, fatal, neurodegenerative disease. Although the pathogenesis remains unresolved, oxidative stress is known to play a pivotal role. Edaravone works in the central nervous system as a potent scavenger of oxygen radicals. In ALS mouse models, edaravone suppresses motor functional decline and nitration of tyrosine residues in the cerebrospinal fluid. Areas covered: Three clinical trials, one phase II open-label trial, and two phase III placebo-control randomized trials were reviewed. In all trials, the primary outcome measure was the changes in scores on the revised ALS functional rating scale (ALSFRS-R) to evaluate motor function of patients. Expert opinion: The phase II open label trial suggested that edaravone is safe and effective in ALS, markedly reducing 3-nitrotyrosine levels in the cerebrospinal fluid. One of the two randomized controlled trials showed beneficial effects in ALSFRS-R, although the differences were not significant. The last trial demonstrated that edaravone provided significant efficacy in ALSFRS-R scores over 24 weeks where concomitant use of riluzole was permitted. Eligibility was restricted to patients with a relatively short disease duration and preserved vital capacity. Therefore, combination therapy with edaravone and riluzole should be considered earlier.

    Receiver operating characteristics (ROC) analysis was performed to evaluate the clinical efficacy of transrectal sonography (US) and computed tomography (CT) for prostatic diseases. One hundred US and CT images of prostatic diseases collected from 10 medical institutions, including 33 cases of prostatic cancer, 29 of benign prostatic hypertrophy, 7 of prostatitis, 2 of prostatic stone and 29 of normal finding, were read by 21 urologists. As the results, US was found to be more useful than CT for both the detection of prostatic diseases and the differentiation between prostatic cancer and benign prostatic hypertrophy. The sensitivity of US for the diagnosis of prostatic cancer was 64.2 % on average of all the urologists. However, the sensitivity was 80.0 % on average of 5 urologists who have read more than 3,000 US images and 59.5 % on average of 16 doctors who have read within 3,000 US images.

  10. Does Digital Game Interactivity Always Promote Self-Efficacy?

    Interactive digital games can promote self-efficacy by engaging players in enactive and observational learning. However, interactivity does not always lead to greater self-efficacy. Important constructs in social cognitive theory, such as performance outcome and perceived similarity, are often not accounted for in studies that have tested the effect of digital game interactivity on self-efficacy. This study assessed the effects of interactive digital games compared with passive digital games based on video comparison, a common experimental design used to test the effect of digital game interactivity on self-efficacy. In addition, this study also evaluated player performance and measured perceived similarity to the observed player. Findings suggested that in general, digital game interactivity predicted higher self-efficacy compared with noninteractive passive games. However, in the noninteractive conditions, the effects of performance on self-efficacy were moderated by perceived similarity between the observer and the observed player. When the observed player was perceived to be similar to the observer, the effects of performance on self-efficacy were comparable to the interactive game, but when the observed player was perceived as dissimilar to the observer, observing the dissimilar player failed to increase observer self-efficacy. Implications for interactivity manipulations and game developers are discussed.

    Hybrid prosthesis supported by natural teeth (overdenture) is widely used in clinical practice and should be executed whenever the clinical conditions suggest it. Through a critical review of the literature, the anatomical, functional, psychological and clinical advantages are emphasized. Among the first ones, the prophylaxis of residual anatomical components, due to the limitation of bone resorption, and the preservation of sensorial proprioception are relevant. Important advantages are also represented by a better crown-root ratio of residual teeth supporting overdenture, with the consequent improvement of the longitudinal prognosis of such teeth. The greater retention and stability of overdenture in comparison with complete denture greatly improve the masticatory efficacy. The psychological advantages resulting from the dental anchorage, which allows the patient to be more confident in social life, are also relevant. Finally, when the dental support is lost, converting overdenture into complete denture is simple and quick, and makes easier the longitudinal clinical maintenance of the denture.

    Neurotrauma continues to represent a challenging public health issue requiring continual improvement in therapeutic approaches. As no such current system exists, we present in this study the Clinical Course Score (CCS) as a new clinical score to evaluate the efficacy of neurotrauma treatment. The CCS was calculated in neurotrauma patients to be the difference between the grade of the Glasgow Outcome Scale 6 months after discharge from our department and the grade of a 1 to 5 point reduced Glasgow Coma Scale on admission. We assessed the CCS in a total of 248 patients (196 traumatic brain injury [TBI] patients and 52 subarachnoid hemorrhage [SAH] patients) who were treated in our Department of Neurosurgery between January 2011 and December 2012. We found negative CCS grades both in mild TBI and in mild SAH patients. In patients with severe TBI or SAH, we found positive CCS grades. In SAH patients, we found higher CCS scores in younger patients compared with elderly subjects in both mild and severe cases. The CCS can be useful in evaluating different therapeutic approaches during neurotrauma therapy. This new score might improve assessment of beneficial effects of therapeutic procedures.

    We studied the epidemiology of 109 cases of gonococcal infections (105 males with urethritis and 4 females with cervicitis), together with the basic and clinical effects of cefetamet pivoxil in the cases. The peak of age distribution of the male patients was in the younger half of their twenties, and all of the 4 female cases were between 20 and 39 years old. The major source of infections in the males younger than 25 years old was their girl friends or so-called pick-up friends, and that of the males older than 25 years old workers serving at an amusement center, for example, bars and so-called special massage parlor, which accounted for about three fourths of the male cases between 35 and 44 years old. The distribution of the MIC (inoculum size; 10(6) CFU/ml) of Cefetamet against beta-lactamase non penicillinase producing Neisseria gonorrhoeae (non-PPNG) ranged from 0.025 to 0.1 microgram/ml and that against beta-lactamase producing Neisseria gonorrhoeae ranged from 0.025 to 0.05 microgram/ml. The isolation rate of PPNG was 10.2% (9/88). In male patients with gonococcal urethritis, the efficacy rate was 100% on days 3 and 7 for 1,000 mg single dose and 7-day treatment and 500 mg single dose treatment. One of the cases treated with 250 mg single dose therapy was unchanged at 3, but the efficacy rate of the remaining cases was 100% at day 7. Complicated urethritis with C. trachomatis was noticed in 25.7% (5/105) of the male urethritis and in 25.0% (1/4) of the female cervicitis cases. The only side effect was diarrhea observed in 1 of the 124 case (0.8%).

    To investigate the efficacy of mouse nerve growth factor (mNGF) in treating occupational hand-arm vibration disease (HAVD). Sixty-four patients with HAVD were equally and randomly divided into treatment group and control group. The control group was given Salvia miltiorrhiza Bunge and deproteinized extract of calf blood to improve circulation, and also given methylcobalamin tablets and vitamin B6 for neurotrophic treatment. In addition to the above treatments for the control group, the treatment group was also given 30 µg/d mNGF by intramuscular injection for two courses (4 weeks for each course) with a 15-day interval. Both the treatment group and the control group showed significant improvements in clinical symptoms and signs (hand numbness and pain, and reduced senses of touch, pain, and vibration), cold water loading test (CWLT), and electroneuromyography (ENMG) after treatments (P hand numbness and pain, reduced senses of touch, pain, and vibration, CWLT, and ENMG, so it has better clinical effect and safety in treating HAVD. Early diagnosis and treatment can improve the outcome of patients with HAVD.

    Mechanical thrombectomy (MT) is increasingly used for large-vessel occlusions (LVO), but randomized clinical trial (RCT) level data with regard to differences in clinical outcomes of MT devices are limited. We conducted a network meta-analysis (NMA) that enables comparison of modern MT devices (Trevo, Solitaire, Aspiration) and strategies (stent retriever vs aspiration) across trials. Relevant RCTs were identified by a systematic review. The efficacy outcome was 90-day functional independence (modified Rankin Scale (mRS) score 0-2). Safety outcomes were 90-day catastrophic outcome (mRS 5-6) and symptomatic intracranial hemorrhage (sICH). Fixed-effect Bayesian NMA was performed to calculate risk estimates and the rank probabilities. In a NMA of six relevant RCTs (SWIFT, TREVO2, EXTEND-IA, SWIFT-PRIME, REVASCAT, THERAPY; total of 871 patients, 472 Solitaire vs medical-only, 108 Aspiration vs medical-only, 178 Trevo vs Merci, and 113 Solitaire vs Merci) with medical-only arm as the reference, Trevo had the greatest functional independence (OR 4.14, 95% credible interval (CrI) 1.41-11.80; top rank probability 92%) followed by Solitaire (OR 2.55, 95% CrI 1.75-3.74; top rank probability 72%). Solitaire and Aspiration devices had the greatest top rank probability with respect to low sICH and catastrophic outcomes (76% and 91%, respectively), but without significant differences between each other. In a separate network of seven RCTs (MR-CLEAN, ESCAPE, EXTEND-IA, SWIFT-PRIME, REVASCAT, THERAPY, ASTER; 1737 patients), first-line stent retriever was associated with a higher top rank probability of functional independence than aspiration (95% vs 54%), with comparable safety outcomes. These findings suggest that Trevo and Solitaire devices are associated with a greater likelihood of functional independence whereas Solitaire and Aspiration devices appear to be safer. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    The choice of appropriate treatment of discogenic low back pain (DLBP) frequently is difficult. This study sought to identify the clinical efficacy of percutaneous endoscopic lumbar annuloplasty and nucleoplasty (PELAN) to treat patients with DLBP and to investigate prognostic clinical or radiologic variables. Eighty-nine patients with a diagnosis of DLBP who underwent PELAN were included. Numeric Rating Scale (NRS) for back pain, Oswestry Disability Index % (ODI%), and modified Macnab criteria were measured at short-term (3-4 weeks) and long-term follow-up period (at least 12 months) to investigate clinical efficacy of PELAN. The subjects were defined as successful group in case of 50% or more reduction of NRS, 40% or more reduction of ODI%, and good or excellent response of Macnab criteria. Clinical and radiologic variables were compared between successful and unsuccessful outcomes group to determine prognostic variables. NRS and ODI% were significantly reduced at short- and long-term follow-up after PELAN. Sixty-two (69.7%) and 68 (76.4%) obtained successful NRS reduction and 59 (66.3%) and 68 (76.4%) accomplished successful ODI% reduction at short-term and long-term follow-up, respectively. Successful Mcnab response was found in 61% at short term and 65.2% at long term. Pain during waist flexion among clinical variables was significantly related to good clinical outcomes and Modic change among radiologic variables was significantly related to poor clinical outcomes. PELAN provided favorable outcomes in patients with DLBP who were refractory to conservative treatments. Flexion pain was good prognostic, and Modic change was a poor prognostic variable.

    The efficacy and benefits of telmisartan in cats with chronic kidney disease (CKD) have not previously been reported. Long-term treatment of cats with CKD using telmisartan decreases urine protein-to-creatinine ratio (UP/C) similar to benazepril. Two-hundred and twenty-four client-owned adult cats with CKD. Prospective, multicenter, controlled, randomized, parallel group, blinded clinical trial with noninferiority design. Cats were allocated in a 1:1 ratio to either telmisartan (1 mg/kg; n = 112) or benazepril (0.5-1.0 mg/kg; n = 112) PO q24 h. The primary endpoint was prospectively defined as the change in proteinuria (benazepril:telmisartan) based on a log transformed weighted average of UP/C change from baseline (AUC 0→t/t) as a percentage compared using a confidence interval (CI) approach. Changes of UP/C from baseline were assessed on all study days and corrected for multiple comparisons. Telmisartan proved noninferior to benazepril in controlling proteinuria (CI, -0.035 to 0.268). At Day 180, UP/C compared to baseline in the telmisartan group was significantly lower (-0.05 ± 0.31; P = .016), whereas in the benazepril group the change (-0.02 ± 0.48) was not statistically significant (P = .136). Similar results were obtained at all assessment points with significant decrease in UP/C occurring with telmisartan but not benazepril. Both telmisartan and benazepril were well tolerated and safe. Telmisartan proved to be noninferior to benazepril and significantly decreased proteinuria relative to baseline at all assessment points whereas benazepril did not. Copyright © 2015 The Authors.

    To investigate the clinical characteristics and the effect of drug treatment for sudden hearing loss with vertigo or dizziness. In a prospective, randomized, single blinded randomized multicenter clinical study, patients with sudden deafness, ranging in age from 18 to 65 years old, with a duration less than 2 weeks, and with no any medical treatments were collected. In accordance with the hearing curve, those patients were divided into four types, i.e., low and intermediate frequency descent type; high frequency descent type; fall flat type; and total deafness type. Each type was treated by four different treatment options, according to the unified design of the random table, and randomly selected one of the options for treatment. The efficacy of the patients with sudden deafness with vertigo and dizziness was analyzed statistically after the follow-up for 4 weeks. SPSS 13.0 software was used to analyze the data. In August 2007 to October 2011, 33 hospitals in the country included 1 024 patients with sudden deafness in line with the inclusion criteria, of whom 296 (28.91%) were accompanied by vertigo/dizziness symptoms, 126 were males and 170 were females, with an average age of (41.2 ± 13.5) years old. types of the different audiometric curves of sudden deafness, the occurrence of complete deafness with vertigo/dizziness was the highest (44.93%), followed by flat down type (25.87%), high frequency descent type (21.28%) and low intermediate frequency descent type (18.54%). After the standard treatment, the vertigo and dizziness symptoms of the sudden deafness patients could disappear, and the hearing in each group was obviously improved. The hearing curative effect on patients accompanied by vertigo/dizziness of low frequency and intermediate frequency descent type was the best, and the total efficiency can reach up to 94.74%, with the cure rate of 68.42%; followed by flat type, in which the total effective rate was 80.76%, with the recovery rate of 22.12%; and

    Topical Acyclovir has moderate efficacy on recurrent HSV symptoms, requiring repeat applications for several days. Topical Dynamiclear, which requires only a single dose application, may provide a more effective and convenient treatment option for symptomatic management of HSV. The study assessed the comparative efficacy and tolerability of a single use, topical formulation containing copper sulfate pentahydrate and Hypericum perforatum that is marketed as Dynamiclear™ to a topical 5% Acyclovir cream standard preparation and use. A prospective, randomized, multi-centered, comparative, open-label clinical study was conducted. A total of 149 participants between 18 and 55 years of age with active HSV-1 and HSV-2 lesions were recruited for the 14-day clinical trial. Participants were randomized into two groups: A (n=61), those receiving the Dynamiclear formulation, and B (n=59), those receiving 5% Acyclovir. Efficacy parameters were assessed via physical examination at baseline (day 1), day 2, 3, 8, and 14. Laboratory safety tests were conducted at baseline and on day 14. Use of the Dynamiclear formulation was found to have no significant adverse effects and was well tolerated by participants. All hematological and biochemical markers were within normal range for the Dynamiclear group. Statistically, odds for being affected by burning and stinging sensation were 1.9 times greater in the Acyclovir group in comparison to the Dynamiclear group. Similarly, the odds of being affected by symptoms of acute pain, erythema and vesiculation were 1.8, 2.4, and 4.4 times higher in the Acyclovir group in comparison to the Dynamiclear group. The Dynamiclear formulation was well tolerated, and efficacy was demonstrated in a number of measured parameters, which are helpful in the symptomatic management of HSV-1 and HSV-2 lesions in adult patients. Remarkably, the effects seen from this product came from a single application.

    Although thalassaemia is highly prevalent in the Asia-Pacific region, clinical data on efficacy and safety profiles of deferasirox in patients from this region are rather limited. Recently, data from the multicentre Evaluation of Patients' Iron Chelation with Exjade (EPIC) study in 1744 patients with different anaemias has provided an opportunity to analyse 1115 thalassaemia patients, of whom 444 patients were from five countries in the Asia-Pacific region (AP) for whom thalassaemia management and choice of iron chelators were similar. Compared to the rest of the world (ROW), baseline clinical data showed that the AP group appeared to be more loaded with iron (3745.0 vs. 2822.0 ng/ml) and had a higher proportion on deferoxamine monotherapy prior to the study (82.9 vs. 58.9%). Using a starting deferasirox dose based on transfusional iron intake and tailoring it to individual patient response, clinical efficacy based on serum ferritin reduction in AP and ROW thalassaemia patients was similar. Interestingly, the AP group developed a higher incidence of drug-related skin rash compared to ROW (18.0 vs. 7.2%), which may indicate different pharmacogenetic backgrounds in the two populations. Our analysis confirms that, with appropriate adjustment of dose, deferasirox can be clinically effective across different regions, with manageable side effects.

    Full Text Available ABSTRACT The stability and the anti-ageing, skin hydrating and anti-erythema effects of a commercialized Crocodylus niloticus Laurenti, 1768, Crocodylidae, oil lotion was determined. The lotion was stored at controlled conditions over six months during which several stability tests were performed. For the clinical efficacy studies lotion was applied on volar forearm skin (female volunteers and compared to a liquid paraffin-containing reference product. Skin hydrating and anti-ageing effects were determined with a Corneometer®, Cutometer® and Visioscan®, following single (3 h and multiple applications (12 weeks. The Vapometer® and Mexameter® were utilized to determine this lotion's anti-erythema effects on sodium lauryl sulfate irritated skin. The lotion demonstrated good stability over 6 months. The reference product increased skin hydration and decreased skin wrinkles to a larger extent than the C. niloticus lotion after a single application, whereas the C. niloticus lotion decreased skin scaliness better than the reference product. During the long-term study, the reference product overall increased skin hydration more than the C. niloticus lotion, whereas C. niloticus lotion increased skin elasticity to a larger extent than the reference product. C. niloticus lotion increased skin wrinkles and decreased skin scaliness over 12 weeks. Compared to non-treated, irritated skin, C. niloticus lotion demonstrated some potential anti-inflammatory characteristics.

    Research suggests that core schemas are important in both the development and maintenance of psychosis. The aim of the study was to investigate and compare core schemas in four groups along the continuum of psychosis and examine the relationships between schemas and positive psychotic symptomatology. A measure of core schemas was distributed to 20 individuals experiencing first-episode psychosis (FEP), 113 individuals with "at risk mental states" (ARMS), 28 participants forming a help-seeking clinical group (HSC), and 30 non-help-seeking individuals who endorse some psychotic-like experiences (NH). The clinical groups scored significantly higher than the NH group for negative beliefs about self and about others. No significant effects of group on positive beliefs about others were found. For positive beliefs about the self, the NH group scored significantly higher than the clinical groups. Furthermore, negative beliefs about self and others were related to positive psychotic symptomatology and to distress related to those experiences. Negative evaluations of the self and others appear to be characteristic of the appraisals of people seeking help for psychosis and psychosis-like experiences. The results support the literature that suggests that self-esteem should be a target for intervention. Future research would benefit from including comparison groups of people experiencing chronic psychosis and people who do not have any psychotic-like experiences.

    To evaluate the efficacy of panoramic radiography by comparing the results of clinical examination with radiographic findings. We studied 190 patients (20 men and 170 women; mean age, 40 years; range, 22 to 68 years) who visited the health promotion center of Korea Medical Science Institute and were examined both clinically and by panoramic radiography. We compared results from both examinations. Treatment options by clinical examination were described as 'no treatment indicated', 'treatment of dental caries', 'removal of calculus', 'treatment of periodontal disease'. 'prothodonic treatment' and 'extraction of the third molar'. Findings taken from the panoramic radiography were: dental caries, peroapical lesion, alveolar bone loss, calculus deposition, retained root, impaction of the third molar, disease of maxillary sinus, bony change of mandibular condyle, etc. The prevalence of panoramic findings were: 37.9% of dental caries, 17.4% of periapical lesions, 44.7% of alveolar bone losses, 62.6% of calculi deposition. 7.9% of retained roots, 26.8% of third molar impactions, 6.3% of disease of maxillary sinus, 2.1% of bony changes of mandibular condlye and 35.8% of miscellaneous lesions. Abnormal conditions revealed by panoramic radiography which had not been discovered on clinical examination were: 24.2% of the patients had dental caries, 17.4% had periapical lesions, 7.4% had calculi deposition, 5.3% had retained roots, 15.3% had third molar impactions. The opposite cases were: 5.2% had dental caries, 12.6% had calculi deposition, and 9.5% had third molar impactions. The use of panoramic radiography as a supplement to the clinical examination might be a valuable screening technique

    With pioglitazone ban and subsequent revoking in India along with varying regulatory decisions in other countries, it was decided to carry out a systematic review on its safety, efficacy and drug utilization in patients with type 2 diabetes mellitus (T2DM) in India and compare with the data from the European Medicines Agency Assessment Report (EMA-AR). Systematic review was performed as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, searching Medline/PubMed, Google Scholar and Science Direct databases using 'pioglitazone AND India AND human' and 'pioglitazone AND India AND human AND patient' and compared with EMA-AR. Spontaneous reports in World Health Organization VigiBase from India were compared with VigiBase data from other countries. Sixty six publications, 26 (efficacy), 32 (drug utilization) and eight (safety), were retrieved. In India, pioglitazone was used at 15-30 mg/day mostly with metformin and sulphonylurea, being prescribed to 26.7 and 8.4 per cent patients in north and south, respectively. The efficacy in clinical trials (CTs) was similar to those in EMA-AR. Incidence of bladder cancer in pioglitazone exposed and non-exposed patients was not significantly different in an Indian retrospective cohort study. There were two cases and a series of eight cases of bladder cancer published but none reported in VigiBase. In India, probably due to lower dose, lower background incidence of bladder cancer and smaller sample size in epidemiological studies, association of bladder cancer with pioglitazone was not found to be significant. Reporting of CTs and adverse drug reactions to Clinical Trials Registry of India and Pharmacovigilance Programme of India, respectively, along with compliance studies with warning given in package insert and epidemiological studies with larger sample size are needed.

    Full Text Available Abstract Background Tenosynovitis is widely accepted to be common in rheumatoid arthritis (RA and postulated to be the first manifestation of RA, but its true prevalence in early disease and in particular the hand has not been firmly established. The aims of this study were first to investigate the frequency and distribution of finger flexor tenosynovitis using ultrasound in early arthritis, second to compare clinical examination with ultrasound (US using the latter as the gold standard. Methods 33 consecutive patients who had who were initially diagnosed with polyarthritis and suspected of polyarthritis and clinical suspicion of inflammatory arthritis of the hands and wrists were assessed during consecutive, routine presentations to the rheumatology outpatient clinic. We scanned a total of 165 finger tendons and subsequent comparisons were made using clinical examination. Results Flexor tenosynovitis was found in 17 patients (51.5% on ultrasound compared with 16 (48.4% of all patients on clinical examination. Most commonly damaged joint involved on US was the second finger followed by the third, fifth, and fourth. Both modalities demonstrated more pathology on the second and third metacarpophalangeal (MCP compared with the fourth and fifth MCP. A joint-by-joint comparison of US and clinical examination demonstrated that although the sensitivity, specificities and positive predictive values of clinical examination were relatively high, negative predictive value of clinical examination was low (0.23. Conclusions Our study suggest that clinical examination can be a valuable tool for detecting flexor disease in view of its high specificity and positive predictive values, but a negative clinical examination does not exclude inflammation and an US should be considered. Further work is recommended to standardize definitions and image acquisition for peritendinous inflammation for ultrasound.

    Full Text Available Abstract Background Our phase III clinical trial of pirfenidone for patients with idiopathic pulmonary fibrosis (IPF revealed the efficacy in reducing the decline of vital capacity (VC and increasing the progression-free survival (PFS time by pirfenidone. Recently, marginal decline in forced VC (FVC has been reported to be associated with poor outcome in IPF. We sought to evaluate the efficacy of pirfenidone from the aspects of 5% change in VC. Methods Improvement ratings based on 5% change in absolute VC, i.e., "improved (VC ≥ 5% increase", "stable (VC Results In the comparison of the improvement ratings, the statistically significant differences were clearly revealed at months 3, 6, 9, and 12 between pirfenidone and placebo groups. Risk reductions by pirfenidone to placebo were approximately 35% over the study period. In the comparison of the PFS times, statistically significant difference was also observed between pirfenidone and placebo groups. The positive/negative predictive values in placebo and pirfenidone groups were 86.1%/50.8% and 87.1%/71.7%, respectively. Further, the baseline characteristics of patients worsened at month 3 had generally severe impairment, and their clinical outcomes including mortality were also significantly worsened after 1 year. Conclusions The efficacy of pirfenidone in Japanese phase III trial was supported by the rating of 5% decline in VC, and the VC changes at month 3 may be used as a prognostic factor of IPF. Trial Registration This clinical trial was registered with the Japan Pharmaceutical Information Center (JAPIC on September 13th, 2005 (Registration Number: JAPICCTI-050121.

    We performed an observational study on the efficacy of bendamustine and rituximab as first salvage regimen in chronic lymphocytic leukemia. In an intention-to-treat analysis including 237 patients, the median progression free survival was 25 months. The presence of del(17p), unmutated IGHV and advanced stage were associated with a shorter progression free survival at multivariate analysis. The median time-to-next treatment was 31.3 months. Front-line treatment with a chemoimmunotherapy regimen was the only predictive factor for a shorter time to next treatment at multivariate analysis. The median overall survival was 74.5 months. Advanced Binet stage (i.e. III-IV or C) and resistant disease were the only parameters significantly associated with a shorter OS. Grade 3-5 infections were recorded in 6.3% of patients. A matched-adjusted indirect comparison with ibrutinib given second-line within named patient programs in the United Kingdom and in Italy was carried out with overall survival as objective endpoint. When restricting the analysis to patients with intact 17p who had received chemoimmunotherapy in first line, the overall survival did not differ between patients treated with ibrutinib (63% alive at 36 months) and patients treated with BR (74.4% alive at 36 months). BR is an efficacious first salvage regimen in chronic lymphocytic leukemia in a real-life population, including the elderly and unfit patients. BR and ibrutinib may be equally effective in terms of overall survival when used as first salvage treatment in patients without 17p deletion. ClinicalTrials.gov identifier: NCT02491398.

    An experience of the first randomatized clinical investigation on the usage of different variants of preoperative X-ray (with simultaneous local UHF hyperthepmia and without it) action in the case of combined treatment of patients with breast cancer has been summarized. It has been shown that conventional values of preoperative X-ray therapy (about 30-45 G.) are optimum ones. An increase of complex thermoradiotherapy efficacy in the case of considered cancer forms may be achieved at the expense of a stre gthening of preoperative X-ray action by means of dose increase up to the cancerogenic level or preoperative irradiation under the conditions of local UHF-hyperthermia

    To study the clinical efficacy of gamma knife and surgery treatment of mesial temporal lobe epilepsy (MTLE) and their effects on EF-Tumt and EF-Tsmt expression. The data of 78 cases of MTLE patients treated in our hospital from April 2011 to March 2013 were retrospectively analyzed. The patients were divided into two groups according to the treatment methods: the surgery group (including 41 cases) and the gamma knife group (including 37 cases). The clinical efficacy, the occurrence and recurrence of complications were evaluated, respectively; meanwhile, the expression of the EF-Tumt protein and EF-Tsmt protein in brain tissue were analyzed. The difference between the efficacy rate of the two groups showed no statistical significance (χ2=0.960, p>0.05). The complication rate of the gamma knife group was significantly lower than that of the control group (χ2=6.430, pknife group was significantly lower than that of the patients in the surgery group (p>0.05). Within the two groups, the positive expression granum of EF-Tsmt protein and EF-Tumt protein of the two groups after treatment were significantly lower than that before treatment (pknife group was obviously more than that of the patients in the surgery group (p0.05). Before and after treatment within the group, the positive cell of EF-Tsmt protein and EF-Tumt protein of the two groups of patients after treatment were significantly lower than that before treatment (p0.05). Both surgery and gamma knife could treat MTLE effectively, and the efficacy may be related to the ability to reduce the expression of EF-Tsmt protein and EF-Tumt protein in brain tissue.

    Full Text Available Noha Rashad,1 Omar Abdel-Rahman2 1Medical Oncology Department, Maadi Armed Forces Hospital, 2Clinical Oncology Department, Faculty of Medicine, Ain Shams University, Cairo, Egypt Abstract: Rolapitant is a highly selective neurokinin-1 receptor antagonist, orally administered for a single dose of 180 mg before chemotherapy with granisetron D1, dexamethasone 8 mg BID on day 2–4. It has a unique pharmacological characteristic of a long plasma half-life (between 163 and 183 hours; this long half-life makes a single use sufficient to cover the delayed emesis risk period. No major drug–drug interactions between rolapitant and dexamethasone or other cytochrome P450 inducers or inhibitors were observed. The clinical efficacy of rolapitant was studied in two phase III trials in highly emetogenic chemotherapy and in one clinical trial in moderately emetogenic chemotherapy. The primary endpoint was the proportion of patients achieving a complete response (defined as no emesis or use of rescue medication in the delayed phase (>24–120 hours after chemotherapy. In comparison to granisetron (10 µg/kg intravenously and dexamethasone (20 mg orally on day 1, and dexamethasone (8 mg orally twice daily on days 2–4 and placebo, rolapitant showed superior efficacy in the control of delayed and overall emesis. This review aims at revising the pharmacological characteristics of rolapitant, offering an updated review of the available clinical efficacy and safety data of rolapitant in different clinical settings, highlighting the place of rolapitant in the management of chemotherapy-induced nausea and vomiting (CINV among currently available guidelines, and exploring the future directions of CINV management.

    Full Text Available It was demonstrated that octacalcium phosphate collagen composite achieved notable bone regeneration in bone defects in preclinical studies. On the basis of the research results, an investigator-initiated exploratory clinical trial was conducted after approval from a local Institutional Review Board. This clinical study was performed as a single-arm non-randomized intervention study. Octacalcium phosphate collagen composite was implanted into a total of 10 cases of alveolar bone defects after tooth extractions and cystectomy. Safety assessment was performed in terms of the clinical course and several consecutive laboratory examinations, and sequential radiographs were used for efficacy assessment. All participants uneventfully completed the clinical trial without major problems in their general condition. Postoperative wound swelling was observed, as also commonly seen in tooth extraction or cystectomy. Although no serious liver dysfunction, renal dysfunction, electrolyte imbalance, or abnormal urinalysis results were recognized, the number of white blood cells and C-reactive protein level temporarily increased after the operation. An increase in radiopacity in the octacalcium phosphate collagen composite–implanted site was observed in all cases. Finally, the border between the original bone and the octacalcium phosphate collagen composite–implanted site became indistinguishable. These results suggest that octacalcium phosphate collagen composite could be utilized safely in clinical situations in the future.

    A large number of aids have been conceived and introduced into clinical practice (nutritional supplements, local dressings, technical innovations) aimed at facilitating and optimising wound healing in both acute and chronic wound settings. Among these advances, negative pressure wound therapy (NPWT) has been introduced during the last 30 years, and has been analysed in over 400 manuscripts of the English, Russian and German literature. Until very recently, vacuum assisted closure (VAC) (KCI, TX, USA) has been the only readily available commercial device that provides localised negative pressure to the wound and is the predominant agent used to deliver NPWT featured in this review. We conducted a comprehensive review of the existing clinical evidence of the English literature on the applications of NPWT in the acute setting of trauma and burns of the lower extremity. Overall, 16 clinical studies have been evaluated and scrutinised as to the safety and the efficacy of this adjunct therapy in the specific environment of trauma. Effectiveness was comparable to the standard dressing and wound coverage methods. The existing clinical evidence justifies its application in lower limb injuries associated with soft tissue trauma.

    Full Text Available BackgroundDengue hemorrhagic fever is the leading cause of hospitalization and death in children living in Asia and Latin America. There is an urgent need for an effective and safe dengue vaccine to reduce morbidity and mortality in this high-risk population given the lack of dengue specific treatment at present. This review aims to determine the efficacy, safety, and immunogenicity of CYD-TDV vaccine in children.MethodsThis is a systematic review including meta-analysis of randomized controlled clinical trial data from Embase, Medline, the Cochrane Library, Web of Science, and ClinicalTrials.gov. Studies that assessed CYD-TDV vaccine efficacy [(1 − RR*100], safety (RR, and immunogenicity (weighted mean difference in children were included in this study. Random effects model was employed to analyze patient-level data extracted from primary studies.ResultsThe overall efficacy of CYD-TDV vaccine was 54% (40–64, while serotype-specific efficacy was 77% (66–85 for DENV4, 75% (65–82 for DENV3, 50% (36–61 for DENV1, and 34% (14–49 for DENV2. 15% (−174–74 vaccine efficacy was obtained for the unknown serotype. Meta-analysis of included studies with longer follow-up time (25 months revealed that CYD-TDV vaccine significantly increased the risk of injection site reactions (RR = 1.1: 1.04–1.17; p-value = 0.001. Immunogenicity (expressed as geometric mean titers in descending order was 439.7 (331.7–547.7, 323 (247 – 398.7, 144.1 (117.9–170.2, and 105 (88.7–122.8 for DENV3, DENV2, DENV1, and DENV4, respectively.ConclusionCYD-TDV vaccine is effective and immunogenic in children overall. Reduced efficacy of CYD-TDV vaccine against DENV2 notoriously known for causing severe dengue infection and dengue outbreaks cause for serious concern. Post hoc meta-analysis of long-term follow-up data (≥25 months from children previously vaccinated with CYD-TDV vaccine is needed to make a conclusion regarding CYD-TDV vaccine

    Full Text Available Purpose: The aim of the study was to compare the clinical efficacy of methylprednisolone with ibuprofen to ibuprofen alone on the postoperative sequelae of surgical removal of impacted third molars. Materials and Methods: The present study was conducted on the 35 patients requiring surgical extraction of bilateral impacted third molars attending the Outpatient Department of Oral and Maxillofacial Surgery, Guru Nanak Dev Dental College and Research Institute. The impacted teeth were removed in two sessions at least 3 weeks apart. The selected patients were randomly put on regimen 1 or regimen II at either the first or second surgery in accordance with randomization plan. The measurements and recordings for pain, swelling, and interincisal distance (mouth opening, were made on 1 st , 3 rd , and 7 th day postoperatively on the scales designed for the purpose. The data recorded was compiled and put to statistical analysis. Results: It was observed from the present study that postoperative sequelae, that is, pain, swelling, and trismus was significantly less in the regimen I group than regimen II group on the 1 st and 3 rd postoperative day. Conclusion: The results of this study substantiate the fact that a single class of drugs (nonsteroidal anti-inflammatory drug (NSAID is less effective in controlling postoperative inflammatory sequelae than the combination of ibuprofen (NSAID and methylprednisolone (corticosteroid following the third molar surgery. Therefore, this pharmaceutical combination should be considered for attenuation of postoperative sequelae in healthy patients undergoing surgical removal of impacted mandibular third molar.

IOP was evaluated at the initial visit and at a follow-up visit scheduled 4–6 weeks later. At the follow-up visit, each patient discussed the clinical results with their physician, chose which medication they preferred to continue using, and were queried regarding the reason for their choice. This paired-eye comparison method is used routinely in clinical practice to assess clinical response and involve patients in decisions regarding treatment. Change in mean IOP from baseline and patient medication choice were the outcome measures.Results: Bimatoprost-treated eyes (n = 52 had a mean IOP reduction of 2.7 mmHg and travoprost-treated eyes (n = 47 had an average decrease of 1.7 mmHg (P = 0.230. Bimatoprost significantly reduced mean IOP (from 19.8 mmHg at baseline to 17.1 mmHg at follow-up, P < 0.0001, as did travoprost (from 19.4 mmHg at baseline to 17.7 mmHg at follow-up, P = 0.009. Latanoprost-treated eyes were excluded from the efficacy analysis due to small sample size (n = 5. For continued therapy, patients chose bimatoprost over travoprost by a factor of 2.4 to 1. Of the 15 patients who gave a reason for their choice, 80% said their decision was based primarily on IOP change.Conclusions: Bimatoprost and travoprost were efficacious in reducing IOP among patients with

    Full Text Available Background: The infertility is associated with psychological consequence including depression, and lack of self-efficacy. Objective: The aim of this study was to compare the pharmacological and no pharmacological strategies in promotion of self-efficacy of infertile women. Materials and Methods: A randomized controlled clinical trial was conducted on 89 infertile women who were recruited from Fatemeh Zahra Infertility and Reproductive Health Research Center and were randomized into three groups; cognitive behavioral therapy (CBT, antidepressant therapy with flouxetine 20 mg daily for 3 month, and a control group. All participants completed Infertility Self-efficacy Inventory (ISE and the Beck Depression Inventory (BDI at the beginning and end of the study. Results: The means ISE scores among the CBT, fluoxetine, and control groups at the beginning and end of the study were 6.1±1.6 vs. 7.2±0.9, 6.4±1.4 vs. 6.9±1.3 and 6.1±1.1 vs. 5.9±1.4 respectively. Both CBT and fluoxetine increased the mean of ISE scores more than control group after intervention (p<0.0001, p=0.033; respectively, but increase in the CBT group was significantly greater than flouxetine group. Finally, there was evidence of high infertility self-efficacy for women exposed to the intervention compared with those in the control group. Also, there was an improvement in depression. Both fluoxetine and CBT decreased significantly the mean of BDI scores more than the control group; decrease in the CBT group was significantly more than that in the fluoxetine group. Conclusion: CBT can serve as an effective psychosocial intervention for promoting self-efficacy of infertile women

    The current CLSI and EUCAST clinical susceptible breakpoint for 600 mg q12h dosing of ceftaroline (active metabolite of ceftaroline fosamil) for Staphylococcus aureus is ≤1 mg/L. Efficacy data for S. aureus infections with ceftaroline MIC ≥2 mg/L are limited. This study was designed to generate in-depth pharmacokinetic/pharmacodynamics (PK/PD) understanding of S. aureus isolates inhibited by ≥ 2 mg/L ceftaroline using an in vitro hollow-fibre infection model (HFIM). The PK/PD target of ceftaroline was investigated against 12 diverse characterized clinical MRSA isolates with ceftaroline MICs of 2 or 4 mg/L using q8h dosing for 24 h. These isolates carried substitutions in the penicillin-binding domain (PBD) and/or the non-PBD. Additionally, PD responses of mutants with ceftaroline MICs ranging from 2 to 32 mg/L were evaluated against the mean 600 mg q8h human-simulated dose over 72 h. The mean stasis, 1 log10-kill and 2 log10-kill PK/PD targets were 29%, 32% and 35% f T>MIC, respectively. In addition, these data suggest that the PK/PD target for MRSA is not impacted by the presence of substitutions in the non-PBD commonly found in isolates with ceftaroline MIC values of ≤ 2 mg/L. HFIM studies with 600 mg q8h dosing demonstrated a sustained long-term bacterial suppression for isolates with ceftaroline MICs of 2 and 4 mg/L. Overall, efficacy was demonstrated against a diverse collection of clinical isolates using HFIM indicating the utility of 600 mg ceftaroline fosamil for S. aureus isolates with MIC ≤4 mg/L using q8h dosing. © The Author 2017.

    The aims of this study were to assess the effectiveness of calcium silicate cement (Biodentine) versus glass ionomer cement (GIC; control group) as indirect pulp capping materials in patients with reversible pulpitis and to compare the effectiveness of cone beam computed tomography (CBCT) versus periapical (PA) radiographs in detecting PA changes at baseline (T0) and at 12 mo (T12) postoperatively. Seventy-two restorations (36 Biodentine, 36 Fuji IX) were placed randomly in 53 patients. CBCT/PA radiographs were taken at T0 and T12. Two calibrated examiners assessed the presence/absence and increase/decrease in the size of existing PA radiolucencies under standardized conditions. The Kappa coefficient evaluated statistically the effectiveness of CBCT versus PA radiographs in detecting PA changes. Chi-square/Mann-Whitney tests were used to evaluate the association between PA changes in CBCT with various clinical measures. Significance was predetermined at α = 0.05. Clinical success rates for Biodentine and Fuji IX GIC were 83.3%. CBCT was significantly more effective in detecting PA radiolucencies compared with radiographs (P = 0.0069). Of the teeth, 65.4% and 90.4% were deemed healthy using CBCT and PA radiographs, respectively, at T12. Healing/healed rates were 17.3%/0%, while new/progressed radiolucency were 30.8%/9.6% with CBCT/PA radiographs, respectively. Seventy-one percent of healed lesions had received Biodentine; 88% of new/progressed lesions received Fuji IX GIC. Teeth presenting with an initial CBCT PA lesion had a failure rate of 63%, whereas teeth with no initial lesion had a failure rate of 16%. Although no statistically significant difference was detected in the clinical efficacy of Biodentine/Fuji IX when used as indirect pulp capping materials in patients with reversible pulpitis, CBCT showed a significant difference in that most healed CBCT lesions had received Biodentine while most that did not heal received Fuji IX. Longer-term follow-up is

This report presents a systematic literature review and comparison of the efficacy and safety of pharmacologic therapies for treating SCI-associated NeP. Methods: Medline, Embase, Cochrane, and Database of Abstracts of Reviews of Effects were searched through December 2011 for randomized, blinded, and controlled clinical trials of SCI-associated NeP meeting predefined inclusion criteria. Efficacy outcomes of interest were pain reduction on the 11-point numeric rating scale (NRS or 100 mm visual analog scale and proportion of patients achieving ≥30% or ≥50% pain reduction. Discontinuations and adverse events (AEs were also assessed, for which Bayesian meta-analytic indirect comparisons were performed. Results: Of the nine studies included in the analysis, samples were <100 patients, except for one pregabalin study (n = 136. Standard errors for the NRS outcome were often not reported, precluding quantitative comparisons across treatments. Estimated 11-point NRS pain reduction relative to placebo was –1.72 for pregabalin, –1.65 for amitriptyline, –1.0 for duloxetine, –1 (median for levetiracetam, –0.27 for gabapentin, 1 (median for lamotrigine, and 2 for dronabinol. Risk ratios relative to placebo for 30% improvement were 0.71 for levetiracetam and 2.56 for pregabalin, and 0.94 and 2.91, respectively, for 50% improvement. Meta-analytic comparisons showed significantly more AEs with pregabalin and tramadol compared with

    Rotavirus is the most common cause of moderate-to-severe infant diarrhoea in developing countries, resulting in enormous morbidity, mortality, and economic burden. A bovine-human reassortant pentavalent rotavirus vaccine (BRV-PV) targeting the globally most common strains was developed in India and tested in a randomized, double-blind, placebo-controlled end-point driven Phase III efficacy clinical trial implemented at six sites across India. Infants 6 to 8weeks of age were randomized (1:1) to receive three oral doses of BRV-PV or placebo at 6, 10, and 14weeks of age along with routine vaccines. Home visit surveillance was conducted to detect severe rotavirus gastroenteritis (SRVGE) and safety outcomes until the children reached two years of age. A total of 3749 infants received BRV-PV while 3751 received placebo. At the time of the primary end-point (when the minimum number of cases needed for analysis were accrued) the vaccine efficacy against SRVGE was 36% (95% CI 11.7, 53.6, p=0.0067) in the per protocol (PP) analysis, and 41.9% (95% CI 21.1, 57.3, p=0.0005) in the intent to treat (ITT) analysis. Vaccine efficacy over the entire follow-up period (until children reached two years of age) was 39.5% (95% CI 26.7, 50, protavirus cases (VSRVGE, Vesikari score≥16) was 60.5% (95% CI 17.7, 81, p=0.0131) at the time of the primary analysis and 54.7% (95% CI 29.7, 70.8, p=0.0004) for the complete follow-period in the PP population. The incidence of solicited, unsolicited, and serious adverse events were similar in both the vaccine and placebo groups. Likewise, the number of intussusceptions and deaths were similar between both groups. Thus, BRV-PV is an effective, well tolerated and safe vaccine in Indian infants.

    This study aimed to compare the clinical efficacy of two anti-inflammatory medications (fenspiride and inhaled beclomethasone [beclomethasone dipropionate]) in patients with stable chronic obstructive pulmonary disease (COPD) over 6 months. DESIGN, METHODS AND PATIENTS: This was a randomised comparison of 58 patients with COPD, divided into five treatment groups: fenspiride (stages 1 and 2), beclomethasone (stage 2), and two control groups (stages 1 and 2). In addition, 64 patients with exacerbations of COPD were evaluated over a 2-week treatment period during which they received either fenspiride or prednisolone. Clinical signs and symptoms of COPD were evaluated every 2 months (aggregated numerical index of signs and symptoms), as were lung function tests (forced vital capacity [FVC], forced expiratory volume in 1 second [FEV1], FEV1/FVC) and a 6-minute walking test. Statistically significant reductions in all evaluated COPD signs and symptoms were achieved with fenspiride in stage 1 COPD. Fenspiride therapy significantly reduced the indices of sputum parameters (8-fold decrease), incidence of dry rales (6-fold decrease), dyspnoea (4-fold decrease) and cough (2.5-fold decrease). In comparison with beclomethasone, fenspiride was superior in stage 2 COPD. In patients with stage 2 COPD, reductions were less marked, but remained significantly superior in the fenspiride group in comparison with the beclomethasone group and the control groups. In patients with exacerbations of COPD, fenspiride had equivalent efficacy to that of systemic corticosteroids. Anti-inflammatory therapy with fenspiride in addition to bronchodilators significantly improved clinical signs and symptoms, external respiratory function tests and physical activity tests in patients with stage 1 COPD. Adjunctive fenspiride therapy was superior to inhaled beclomethasone in stage 2 COPD. Anti-inflammatory therapy in COPD may be more effective at an early stage of this disease.

    This study was aimed to assess clinical safety and efficacy of the LVIS Jr. microstent in stent-assisted coil embolization of wide-neck intracranial aneurysms. IRB approved single-center interventional clinical study in 22 patients (10 females, 12 males, mean age 55, age range 33-74 years) for the endovascular treatment of wide-neck aneurysms. After obtaining informed consent, patients were included according to the following criteria: aneurysm fundus-to-neck ratio 4 mm, and a parent vessel diameter of ≤3.5 mm. Primary end point for clinical safety was absence of death, absence of major or minor stroke, and absence of transient ischemic attack. Primary end point for treatment efficacy was complete angiographic occlusion according to the Raymond-Roy Occlusion Classification (RROC) immediately after the procedure and at follow-up after 3 and 6 months on magnetic resonance imaging (MRI). In 20/22 (91 %) of patients, the primary end point of safety was reached; in the two remaining patients, transient ischemic attack, but no permanent deficit was observed; in 16/22 (73 %), efficient occlusion (RROC1) was reached, and in 6/22 (27 %), a residual neck remained (RROC2). Single [seven with antegrade, two in crossover configuration, and four with ''first-balloon-then-stent'' (FBTS) technique] or double-stent (eight patients with Y configuration and one patient with X configuration) deployment was technically successful in all cases. Deployment of the LVIS Jr. microstent in various single- or double-stent configurations is safe and effective to assist the treatment of intracranial wide-neck aneurysms. (orig.)

Background CCBs inhibit a variety of cytochrome P-450 enzymes, some...... patients treated and not treated with clopidogrel, with a hazard ratio of 1.15 (95% confidence interval [CI]: 1.07 to 1.24) and 1.05 (95% CI: 1.01 to 1.11), respectively. The increased risk was independent of clopidogrel use; the hazard rate ratio was 1.08 (95% CI: 0.99 to 1.18). Analyses of all additional...... adverse end points and propensity score–matched models provided similar results. Conclusions The clinical efficacy of clopidogrel in patients with a recent MI is not modified by concomitant CCB treatment. This potential drug interaction is unlikely to have clinical significance....

    Full Text Available Background and Aims: The perioperative behavioural studies demonstrate that children are at greater risk of experiencing turbulent anaesthetic induction and adverse behavioural sequelae. We aimed to compare the efficacy of midazolam 0.5 mg/kg with triclofos sodium 100 mg/kg as oral premedication in children undergoing elective surgery. Methods: In this prospective, randomised and double-blind study, sixty children posted for elective lower abdominal surgery were enrolled. The patients were randomly divided into midazolam group (Group M and triclofos sodium group (Group T of thirty each. Group M received oral midazolam 0.5 mg/kg 30 min before induction, and Group T received oral triclofos sodium 100 mg/kg 60 min before induction. All children were evaluated for level of sedation after premedication, behaviour at the time of separation from parents and at the time of mask placement for induction of anaesthesia. Mann–Whitney U-test was used for comparing the grade of sedation, ease of separation and acceptance of face mask. Results: Oral midazolam produced adequate sedation in children after premedication in comparison to oral triclofos (P = 0.002. Both drugs produced successful separation from parents, and the children were very cooperative during induction. No adverse effects attributable to the premedicants were seen. Conclusions: Oral midazolam is superior to triclofos sodium as a sedative anxiolytic in paediatric population.

    Urethra repair by tissue engineering has been extensively studied in laboratory animals and patients, but is not routinely used in clinical practice. To systematically investigate preclinical and clinical evidence of the efficacy of tissue engineering for urethra repair in order to stimulate translation of preclinical studies to the clinic. A systematic search strategy was applied in PubMed and EMBASE. Studies were independently screened for relevance by two reviewers, resulting in 80 preclinical and 23 clinical studies of which 63 and 13 were selected for meta-analysis to assess side effects, functionality, and study completion. Analyses for preclinical and clinical studies were performed separately. Full circumferential and inlay procedures were assessed independently. Evaluated parameters included seeding of cells and type of biomaterial. Meta-analysis revealed that cell seeding significantly reduced the probability of encountering side effects in preclinical studies. Remarkably though, cells were only sparsely used in the clinic (4/23 studies) and showed no significant reduction of side effects. ln 21 out of 23 clinical studies, decellularized templates were used, while in preclinical studies other biomaterials showed promising outcomes as well. No direct comparison to current clinical practice could be made due to the limited number of randomized controlled studies. Due to a lack of controlled (pre)clinical studies, the efficacy of tissue engineering for urethra repair could not be determined. Meta-analysis outcome measures were similar to current treatment options described in literature. Surprisingly, it appeared that favorable preclinical results, that is inclusion of cells, were not translated to the clinic. Improved (pre)clinical study designs may enhance clinical translation. We reviewed all available literature on urethral tissue engineering to assess the efficacy in preclinical and clinical studies. We show that improvements to (pre)clinical study

Methods Eighty-one patients with locally advanced breast cancer were selected from those who were admitted into 309 Hospital of PLA from January 2009 to October 2013, consisting of 65 patients in stage Ⅲa and 16 in stage Ⅲb, and they were treated with neoadjuvant chemotherapy combined with breast-conserving surgery. The clinical efficacy [complete response (CR, partial response (PR, stable disease (SD and progress disease (PD] was observed during follow-up. Results All the patients were followed-up for 12-60 months with a median of 34 months. There were 12 CR patients (14.8%, including 4 with pathological complete response (4.9%, and 52 PR patients (64.2%, 17 SD patients (21.0%. No PD was observed. The overall response rate(ORR was 79.0%(64/81. After follow-up for 12-60 months (median 34 months, distant metastasis to the lung, liver, meninges and bone occurred in 3 patients (3.7%, 3/81 and 1 of them died. Forty-eight patients received breastconserving surgery. The local recurrence rate was 6.3% (3/48. Assessment of cosmetic result was carried out in 48 patients who received breast-conserving surgery and comprehensive treatment for one year, and excellent results were obtained in 14.6% (7/48, good in 43.8% (21/48, and poor in 41.7% (20/48. Conclusions The therapeutic efficacy of locally advanced breast cancer is satisfactory by neoadjuvant chemotherapy and breast-conserving surgery. Standardization of excision and postoperative radiotherapy, systemic comprehensive treatment is the key to the success of the treatment. DOI: 10.11855/j.issn.0577-7402.2015.06.14

    Transcranial direct current stimulation (tDCS) is a non-invasive neuromodulation technique, which can be used to selectively disrupt patterns of neural activity that are associated with symptoms of mental illness. tDCS has been implemented in numerous therapeutic trials across a range of patient populations, with a rapidly increasing number of studies being published each year. This systematic review aimed to evaluate the efficacy of tDCS in the treatment of psychiatric disorders. Four electronic databases were searched from inception until December 2015 by two independent reviewers, and 66 eligible studies were identified. Depression was the most extensively researched condition, followed by schizophrenia and substance use disorders. Data on obsessive compulsive disorder, generalised anxiety disorder, and anorexia nervosa were also obtained. The quality of included studies was appraised using a standardised assessment framework, which yielded a median score corresponding to "weak" on the three-point scale. This improved to "moderate" when case reports/series were excluded from the analysis. Overall, data suggested that tDCS interventions comprising multiple sessions can ameliorate symptoms of several major psychiatric disorders, both acutely and in the long-term. Nevertheless, the tDCS field is still in its infancy, and several methodological and ethical issues must be addressed before clinical efficacy can truly be determined. Studies probing the mechanisms of action of tDCS and those facilitating the definition of optimised stimulation protocols are warranted. Furthermore, evidence from large-scale, multi-centre randomised controlled trials is required if the transition of this therapy from the laboratory to the clinic is to be considered.

    Full Text Available The development of gene therapy vectors for treating diseases of the cardiovascular system continues at a steady pace. Moreover, in the field of gene therapy the utility of "disease-specific promoters" has strong appeal. Many therapeutic genes, including transforming growth factor beta 1 or interleukin 10, are associated to adverse effects. The use of a disease-specific promoter might minimize toxicity. The lectin-like oxidized low density lipoprotein receptor 1 is a marker of cardiovascular disease and a potential therapeutic target. The lectin-like oxidized low density lipoprotein receptor 1 is known to be up-regulated early during disease onset in a number of cell types at the sites where the disease will be clinically evident. In this study an adeno-associated virus-2 DNA vector (AAV2 using the AAV8 capsid, and containing the full length The lectin-like oxidized low density lipoprotein receptor 1 promoter, was generated and assayed for its ability to express human interleukin 10 in low density lipoprotein receptor knockout mice on high cholesterol diet. The cytomegalovirus early promoter was used for comparison in a similarly structured vector. The two promoters were found to have equal efficacy in reducing atherogenesis as measured by aortic systolic blood velocity, aortic cross sectional area, and aortic wall thickness. This is the first head-to-head comparison of a constitutive with a disease-specific promoter in a therapeutic context. These data strongly suggest that the use of a disease-specific promoter is appropriate for therapeutic gene delivery.

    Millions of individuals with obstructive sleep apnoea (OSA) are treated by CPAP aimed at reducing blood pressure (BP) and thus cardiovascular risk. However, evidence is scarce concerning the impact of different CPAP modalities on BP evolution. This double-blind, randomised clinical trial of parallel groups of patients with OSA indicated for CPAP treatment compared the efficacy of fixed-pressure CPAP (FP-CPAP) with auto-adjusting CPAP (AutoCPAP) in reducing BP. The primary endpoint was the change in office systolic BP after 4 months. Secondary endpoints included 24 h BP measurements. Patients (322) were randomised to FP-CPAP (n=161) or AutoCPAP (n=161). The mean apnoea+hypopnoea index (AHI) was 43/h (SD, 21); mean age was 57 (SD, 11), with 70% of males; mean body mass index was 31.3 kg/m(2) (SD, 6.6) and median device use was 5.1 h/night. In the intention-to-treat analysis, office systolic blood pressure decreased by 2.2 mm Hg (95% CI -5.8 to 1.4) and 0.4 mm Hg (-4.3 to 3.4) in the FP-CPAP and AutoCPAP group, respectively (group difference: -1.3 mm Hg (95% CI -4.1 to 1.5); p=0.37, adjusted for baseline BP values). 24 h diastolic BP (DBP) decreased by 1.7 mm Hg (95% CI -3.9 to 0.5) and 0.5 mm Hg (95% CI -2.3 to 1.3) in the FP-CPAP and AutoCPAP group, respectively (group difference: -1.4 mm Hg (95% CI -2.7 to -0.01); p=0.048, adjusted for baseline BP values). The result was negative regarding the primary outcome of office BP, while FP-CPAP was more effective in reducing 24 h DBP (a secondary outcome). NCT01090297.

    Thiopurine hypermethylation towards 6-methylmercaptopurine (6MMP) instead of 6-thioguanine nucleotides (6TGN) is associated with inefficacy in patients with IBD. Allopurinol reverses such hypermethylation. To prospectively determine efficacy of allopurinol-thiopurine combination and to compare 2 doses of allopurinol. In a multicentre, double-blind trial, patients with clinically active or steroid-dependent IBD and thiopurine shunting were randomised to 50 or 100 mg/d allopurinol and 25% of their screening thiopurine dose, which was subsequently optimised, aiming for 6TGN of 260-500 pmol/8x10 8 RBCs. The primary endpoint was steroid-free clinical remission at 24 weeks. Of 73 patients, 39 (53% [95% CI 42-65]) achieved steroid-free remission, (54% with 50 mg/d and 53% with 100 mg/d). 81% were able to discontinue steroids. Therapeutic 6TGN levels were achieved in both groups. Final thiopurine doses were lower with 100 mg/d allopurinol (P stability and lower thiopurine dose without additional toxicity. © 2018 John Wiley & Sons Ltd.

    To evaluate student self-efficacy, knowledge and communication with teen issues and learning activities. Data were collected during the 8-week pediatric rotation for third-year medical students at a local children's hospital. Students completed a self-efficacy instrument at the beginning and end of the rotation; knowledge and communication skills were evaluated during standardized patient cases as part of the objective structured clinical examination. Self-efficacy, knowledge and communication frequencies were described with descriptive statistics; differences between groups were also evaluated utilizing two-sample t-tests. Self-efficacy levels of both groups increased by the end of the pediatric rotation, but students in the two-lecture group displayed significantly higher self-efficacy in confidentiality with adolescents (t(35)=-2.543, p=0.02); interviewing adolescents, assessing risk, sexually transmitted infection risk and prevention counseling, contraception counseling were higher with marginal significance. No significant differences were found between groups for communication; assessing sexually transmitted infection risk was marginally significant for knowledge application during the clinical exam. Medical student self-efficacy appears to change over time with effects from different learning methods; this higher self-efficacy may increase future comfort and willingness to work with this high-risk, high-needs group throughout a medical career.

    Compliant flooring, broadly defined as flooring systems or floor coverings with some level of shock absorbency, may reduce the incidence and severity of fall-related injuries in older adults; however, a lack of synthesized evidence may be limiting widespread uptake. Informed by the Arksey and O'Malley framework and guided by a Research Advisory Panel of knowledge users, we conducted a scoping review to answer: what is presented about the biomechanical efficacy, clinical effectiveness, cost-effectiveness, and workplace safety associated with compliant flooring systems that aim to prevent fall-related injuries in healthcare settings? We searched academic and grey literature databases. Any record that discussed a compliant flooring system and at least one of biomechanical efficacy, clinical effectiveness, cost-effectiveness, or workplace safety was eligible for inclusion. Two independent reviewers screened and abstracted records, charted data, and summarized results. After screening 3611 titles and abstracts and 166 full-text articles, we included 84 records plus 56 companion (supplementary) reports. Biomechanical efficacy records (n = 50) demonstrate compliant flooring can reduce fall-related impact forces with minimal effects on standing and walking balance. Clinical effectiveness records (n = 20) suggest that compliant flooring may reduce injuries, but may increase risk for falls. Preliminary evidence suggests that compliant flooring may be a cost-effective strategy (n = 12), but may also result in increased physical demands for healthcare workers (n = 17). In summary, compliant flooring is a promising strategy for preventing fall-related injuries from a biomechanical perspective. Additional research is warranted to confirm whether compliant flooring (i) prevents fall-related injuries in real-world settings, (ii) is a cost-effective intervention strategy, and (iii) can be installed without negatively impacting workplace safety.

    Oral nifedipine is commonly used to treat pre-eclampsia, one of the most severe complications during pregnancy, but its clinical efficacy is less than ideal. Epigallocatechin gallate (EGCG), a natural compound from green tea, could benefit cardiovascular health especially hypertension. We investigated the clinical efficacy of EGCG, when complemented with oral nifedipine, in treating pre-eclampsia. A total of 350 pregnant women with severe pre-eclampsia were recruited and randomized to receive oral nifedipine, together with placebo (NIF+placebo) or EGCG (NIF+EGCG). The primary treatment outcome was the time needed to control blood pressure and interval time before a new hypertensive crisis, whereas the secondary treatment outcome was the number of treatment doses to effectively control blood pressure, maternal adverse effects and neonatal complications. Comparing NIF+EGCG group to NIF+placebo group, the time needed to control blood pressure was significantly shorter (NIF+EGCG 31.2±16.7 minutes, NIF+placebo 45.3±21.9 minutes; 95% CI 9.7-18.5 minutes), whereas interval time before a new hypertensive crisis was significantly prolonged (NIF+EGCG 7.2±2.9 hours, NIF+placebo 4.1±3.7 hours; 95% CI 2.3-3.9 hours), and the number of treatment dosages needed to effectively control blood pressure was also lower. Between the two treatment groups, no differences in incidence rates of maternal adverse effects or neonatal complications were observed. EGCG is both safe and effective in enhancing treatment efficacy of oral nifedipine against pregnancy-induced severe pre-eclampsia, but formal validation is required prior to its recommendation for use outside of clinical trials. © 2017 John Wiley & Sons Ltd.

    Full Text Available To run a systematic review and meta-analysis of randomized clinical trials aiming to answer the clinical question "which analgesic combination and dosage is potentially the most effective and safe for acute post-operative pain control after third molar surgery?".A systematic search of computer databases and journals was performed. The search and the evaluations of articles were performed by 2 independent reviewers in 3 rounds. Randomized clinical trials related to analgesic combinations for acute post-operative pain control after lower third molar surgery that matched the selection criteria were evaluated to enter in the final review.Fourteen studies with 3521 subjects, with 10 groups (17 dosages of analgesic combinations were included in the final review. The analgesic efficacy were presented by the objective pain measurements including sum of pain intensity at 6 hours (SPID6 and total pain relief at 6 hours (TOTPAR6. The SPID6 scores and TOTPAR6 scores of the reported analgesic combinations were ranged from 1.46 to 6.44 and 3.24 - 10.3, respectively. Ibuprofen 400mg with oxycodone HCL 5mg had superior efficacy (SPID6: 6.44, TOTPAR6: 9.31. Nausea was the most common adverse effect, with prevalence ranging from 0-55%. Ibuprofen 200mg with caffeine 100mg or 200mg had a reasonable analgesic effect with fewer side effects.This systematic review and meta-analysis may help clinicians in their choices of prescribing an analgesic combination for acute post-operative pain control after lower third molar surgery. It was found in this systematic review Ibuprofen 400mg combined with oxycodone HCL 5mg has superior analgesic efficacy when compared to the other analgesic combinations included in this study.

    Full Text Available Background: Tumor necrosis factor α (TNFα antagonists, namely, golimumab, adalimumab, infliximab, etanercept and certolizumab have been prescribed to alleviate and treat ankylosing spondylitis (AS. However, the lack of comparative evidence does not enable us to make constructive recommendations particularly for AS patient populations. Methods: Eligible controlled trials regarding the above 5 anti-TNFα therapies were searched electronically through PubMed, Embase and Cochrane until April 1, 2015. Odds ratios (ORs were estimated and compared for efficacy (ASAS20, ASAS40, ASAS5/6 responses and ASAS partial remission and acceptability (serious adverse effects (SAE among the anti-TNFα reagents. Results: Totally, 25 trials with 2989 participants were incorporated in this mixed treatment comparison. All the 5 TNFα blockers achieved better ASAS20, ASAS40, ASAS5/6 and ASAS-PR responses than the placebo. Furthermore, there was no significant distinction existed among inter-drug comparisons, except that unfavorable effects induced by certolizumab seemed to be less severe than those by etanercept (OR = 0.22, 95% CI: 0.05-0.93. Apart from that, etanercept was estimated to arrive at the most favorable ASAS20 response (90.6% and SAE (83.6%, while infliximab seemed to accomplish the best ASAS40 (83.6% and ASAS-PR responses (77.3%. In addition, adalimumab was estimated to rank the highest ASAS5/6 response (75.0%. Conclusions: Etanercept, infliximab and adalimumab might be prioritized among the commonly recognized 5 anti-TNFα therapies specific for AS patients, though existing evidence did not suffice to confirm significant superiority among the above 5 anti-TNFα reagent.

    Recent studies have suggested that long-term oxytocin administration can alleviate the symptoms of autism spectrum disorder (ASD); however, factors influencing its efficacy are still unclear. We conducted a single-center phase 2, pilot, randomized, double-blind, placebo-controlled, parallel-group, clinical trial in young adults with high-functioning ASD, to determine whether oxytocin dosage and genetic background of the oxytocin receptor affects oxytocin efficacy. This trial consisted of double-blind (12 weeks), open-label (12 weeks) and follow-up phases (8 weeks). To examine dose dependency, 60 participants were randomly assigned to high-dose (32 IU per day) or low-dose intranasal oxytocin (16 IU per day), or placebo groups during the double-blind phase. Next, we measured single-nucleotide polymorphisms (SNPs) in the oxytocin receptor gene (OXTR). In the intention-to-treat population, no outcomes were improved after oxytocin administration. However, in male participants, Clinical Global Impression-Improvement (CGI-I) scores in the high-dose group, but not the low-dose group, were significantly higher than in the placebo group. Furthermore, we examined whether oxytocin efficacy, reflected in the CGI-I scores, is influenced by estimated daily dosage and OXTR polymorphisms in male participants. We found that >21 IU per day oxytocin was more effective than ⩽21 IU per day, and that a SNP in OXTR (rs6791619) predicted CGI-I scores for ⩽21 IU per day oxytocin treatment. No severe adverse events occurred. These results suggest that efficacy of long-term oxytocin administration in young men with high-functioning ASD depends on the oxytocin dosage and genetic background of the oxytocin receptor, which contributes to the effectiveness of oxytocin treatment of ASD.

  15. A new cognitive evaluation battery for Down syndrome and its relevance for clinical trials

    Full Text Available The recent prospect of pharmaceutical interventions for cognitive impairment of Down syndrome(DS has boosted a number of clinical trials in this population. However, running the trials has raised some methodological challenges and questioned the prevailing methodology used to evaluate cognitive functioning of DS individuals. This is usually achieved by comparing DS individuals to matched healthy controls of the same mental age. We propose a new tool, the TESDAD Battery that uses comparison with age-matched typically developed adults. This is an advantageous method for probing the clinical efficacy of DS therapies, allowing the interpretation and prediction of functional outcomes in clinical trials. In our DS population the TESDAD battery permitted a quantitative assessment of cognitive defects, which indicated language dysfunction and deficits in executive function, as the most important contributors to other cognitive and adaptive behavior outcomes as predictors of functional change in DS. Concretely, auditory comprehension and functional academics showed the highest potential as end-point measures of therapeutic intervention for clinical trials: the former as a cognitive key target for therapeutic intervention, and the latter as a primary functional outcome measure of clinical efficacy. Our results also emphasize the need to explore the modulating effects of IQ, gender and age on cognitive enhancing treatments. Noticeably, women performed significantly better than men of the same age and IQ in most cognitive tests, with the most consistent differences occurring in memory and executive functioning and negative trends rarely emerged on quality of life linked to the effect of age after adjusting for IQ and gender. In sum, the TESDAD battery is a useful neurocognitive tool for probing the clinical efficacy of experimental therapies in interventional studies in the DS population suggesting that age-matched controls are advantageous for determining

    Purpose We assessed the long-term efficacy and safety of human retinal progenitor cells (hRPC) using established rodent models. Methods Efficacy of hRPC was tested initially in Royal College of Surgeons (RCS) dystrophic rats immunosuppressed with cyclosporine/dexamethasone. Due to adverse effects of dexamethasone, this drug was omitted from a subsequent dose-ranging study, where different hRPC doses were tested for their ability to preserve visual function (measured by optokinetic head tracking) and retinal structure in RCS rats at 3 to 6 months after grafting. Safety of hRPC was assessed by subretinal transplantation into wild type (WT) rats and NIH-III nude mice, with analysis at 3 to 6 and 9 months after grafting, respectively. Results The optimal dose of hRPC for preserving visual function/retinal structure in dystrophic rats was 50,000 to 100,000 cells. Human retinal progenitor cells integrated/survived in dystrophic and WT rat retina up to 6 months after grafting and expressed nestin, vimentin, GFAP, and βIII tubulin. Vision and retinal structure remained normal in WT rats injected with hRPC and there was no evidence of tumors. A comparison between dexamethasone-treated and untreated dystrophic rats at 3 months after grafting revealed an unexpected reduction in the baseline visual acuity of dexamethasone-treated animals. Conclusions Human retinal progenitor cells appear safe and efficacious in the preclinical models used here. Translational Relevance Human retinal progenitor cells could be deployed during early stages of retinal degeneration or in regions of intact retina, without adverse effects on visual function. The ability of dexamethasone to reduce baseline visual acuity in RCS dystrophic rats has important implications for the interpretation of preclinical and clinical cell transplant studies.

    To investigate the comparative efficacy of bevacizumab (Avastin) and ranibizumab (Lucentis; both Genentech, Inc, South San Francisco, CA) for diabetic macular edema (DME) using a crossover study design. Randomized, double-masked, 36-week, 3-period crossover clinical trial. Fifty-six subjects with DME involving the center of the macula in one or both eyes. Monthly intravitreous injections of bevacizumab (1.25 mg) or ranibizumab (0.3 mg). Comparison of mean changes in visual acuity and central retinal thickness, tested using a linear mixed-effects model. Based on the linear mixed-effects model, the 3-month estimated mean improvement in visual acuity was 5.3 letters for bevacizumab and 6.6 letters for ranibizumab (difference, 1.3 letters; P = 0.039). Estimated change in optical coherence tomography (OCT) central subfield mean thickness (CSMT) was -89 μm for bevacizumab and -137 μm for ranibizumab (difference, 48 μm; P < 0.001). Incorporating cumulative treatment benefit, the model yielded a predicted 36-week (9-month) average improvement in visual acuity of 7.1 letters (95% confidence interval [CI], 5.0-9.2) for bevacizumab and 8.4 letters (95% CI, 6.3-10.5) for ranibizumab, and a change in OCT CSMT of -128 μm (95% CI, -155 to -100) for bevacizumab and -176 μm (95% CI, -202 to -149) for ranibizumab. There was no significant treatment-by-period interaction (i.e., treatment difference was constant in all 3 periods), nor was there a significant differential carryover effect from one period to the next. This trial demonstrated a statistically significant but small relative clinical benefit of ranibizumab compared with bevacizumab for treatment of DME, using a markedly reduced sample size relative to a full comparative efficacy study. The effects on visual acuity and central retinal thickness for the 2 drugs are consistent with those reported at 1 year for the concurrent parallel-group trial by the Diabetic Retinopathy Clinical Research Network testing bevacizumab

    Full Text Available There is no evidence that the epinephrine-3% hypertonic saline combination is more effective than 3% hypertonic saline alone for treating infants hospitalized with acute bronchiolitis. We evaluated the efficacy of nebulized epinephrine in 3% hypertonic saline.We performed a randomized, double-blind, placebo-controlled clinical trial in 208 infants hospitalized with acute moderate bronchiolitis. Infants were randomly assigned to receive nebulized 3% hypertonic saline with either 3 mL of epinephrine or 3 mL of placebo, administered every four hours. The primary outcome measure was the length of hospital stay.A total of 185 infants were analyzed: 94 in the epinephrine plus 3% hypertonic saline group and 91 in the placebo plus 3% hypertonic saline group. Baseline demographic and clinical characteristics were similar in both groups. Length of hospital stay was significantly reduced in the epinephrine group as compared with the placebo group (3.94 ±1.88 days vs. 4.82 ±2.30 days, P = 0.011. Disease severity also decreased significantly earlier in the epinephrine group (P = 0.029 and P = 0.036 on days 3 and 5, respectively.In our setting, nebulized epinephrine in 3% hypertonic saline significantly shortens hospital stay in hospitalized infants with acute moderate bronchiolitis compared to 3% hypertonic saline alone, and improves the clinical scores of severity from the third day of treatment, but not before.EudraCT 2009-016042-57.

    The objective of this study was to evaluate the technical aspects and clinical efficacy of selective embolization for post-endoscopic sphincterotomy bleeding. We reviewed the records of 10 patients (3%; M:F 6:4; mean age, 63.3 years) that underwent selective embolization for post-endoscopic sphincterotomy bleeding among 344 patients who received arteriography for nonvariceal upper gastrointestinal bleeding from 2000 to 2009. We analyzed the endoscopic procedure, onset of bleeding, underlying clinical condition, angiographic findings, interventional procedure, and outcomes in these patients. Among the 12 bleeding branches, primary success of hemostasis was achieved in 10 bleeding branches (83%). Secondary success occurred in two additional bleeding branches (100%) after repeated embolization. In 10 patients, post-endoscopic sphincterotomy bleedings were detected during the endoscopic procedure (n = 2, 20%) or later (n = 8, 80%), and the delay was from one to eight days (mean, 2.9 days; {+-} 2.3). Coagulopathy was observed in three patients. Eight patients had a single bleeding branch, whereas two patients had two branches. On the selective arteriography, bleeding branches originated from the posterior pancreaticoduodenal artery (n = 8, 67%) and anterior pancreaticoduodenal artery (n = 4, 33%), respectively. Superselection was achieved in four branches and the embolization was performed with n-butyl cyanoacrylate. The eight branches were embolized by combined use of coil, n-butyl cyanoacrylate, or Gelfoam. After the last embolization, there was no rebleeding or complication related to embolization. Selective embolization is technically feasible and an effective procedure for post-endoscopic sphincterotomy bleeding. In addition, the posterior pancreaticoduodenal artery is the main origin of the causative vessels of post-endoscopic sphincterotomy bleeding.

    The objective of this study was to evaluate the technical aspects and clinical efficacy of selective embolization for post-endoscopic sphincterotomy bleeding. We reviewed the records of 10 patients (3%; M:F 6:4; mean age, 63.3 years) that underwent selective embolization for post-endoscopic sphincterotomy bleeding among 344 patients who received arteriography for nonvariceal upper gastrointestinal bleeding from 2000 to 2009. We analyzed the endoscopic procedure, onset of bleeding, underlying clinical condition, angiographic findings, interventional procedure, and outcomes in these patients. Among the 12 bleeding branches, primary success of hemostasis was achieved in 10 bleeding branches (83%). Secondary success occurred in two additional bleeding branches (100%) after repeated embolization. In 10 patients, post-endoscopic sphincterotomy bleedings were detected during the endoscopic procedure (n = 2, 20%) or later (n = 8, 80%), and the delay was from one to eight days (mean, 2.9 days; ± 2.3). Coagulopathy was observed in three patients. Eight patients had a single bleeding branch, whereas two patients had two branches. On the selective arteriography, bleeding branches originated from the posterior pancreaticoduodenal artery (n = 8, 67%) and anterior pancreaticoduodenal artery (n = 4, 33%), respectively. Superselection was achieved in four branches and the embolization was performed with n-butyl cyanoacrylate. The eight branches were embolized by combined use of coil, n-butyl cyanoacrylate, or Gelfoam. After the last embolization, there was no rebleeding or complication related to embolization.

    AS2077715 is a novel antifungal metabolite produced by the newly isolated fungal strain Capnodium sp. 339855. This compound has potent inhibitory activity against Trichophyton mentagrophytes mitochondrial cytochrome bc1 complex (complex III) and potent fungicidal activity against T. mentagrophytes, as measured in vitro. Here, we compared the effects of AS2077715 and terbinafine in a guinea pig model of tinea pedis. In a treatment regimen started from the day 7 after infection, 10 daily oral doses of 10 and 20 mg kg(-1) AS2077715 and 20 mg kg(-1) of terbinafine significantly decreased fungal colony-forming units (CFUs) in foot pad skin. In a treatment regimen started from the day 11 after infection, 20 mg kg(-1) AS2077715 significantly reduced fungal CFUs in foot pad skin after 7 daily doses in comparison with 20 mg kg(-1) terbinafine-treated guinea pigs. Our findings suggest that in vivo potency and efficacy of AS2077715 are equal to or greater than that of terbinafine, positioning AS2077715 as a good candidate for use in treating trichophytosis.

    Self-efficacy has been shown to influence student engagement, effort and performance as well as course selection and future career choice. Extending our knowledge regarding the development of self-efficacy has important implications for educators and for those concerned about the international uptake of science careers. Previous research has identified four sources that may contribute towards self-efficacy: mastery experiences, vicarious experiences, verbal persuasion and physiological/affective states. Very little research has been conducted within the school environment that looks at the formation of these sources and yet early school experiences have been posited to be a key factor in girls' lack of engagement in post compulsory science education. This paper investigates children's self-efficacy beliefs in science and reports on findings from mixed method research conducted with 182 children aged between 10 and 12 years. Classroom data were collected through focus groups, individual interviews and surveys. Findings revealed that although girls and boys held similar levels of academic performance in science, many girls underestimated their capability. The four sources of self-efficacy identified by Bandura (1997) plus self-regulation as an additional source, were evident in the children's descriptions, with boys being more influenced by mastery experience and girls by a combination of vicarious experience and physiological/affective states. Girl's appraisal of information appeared to operate through a heuristic process whereby girls disregarded salient information such as teacher feedback in favour of reliance on social comparison. Contextual factors were identified. Implications for science teachers are discussed.

    Transcatheter Amplatzer occlusion of patent ductus artertiosus (PDA) has emerged as a minimally invasive alternative to surgical closure. The goal of this study was to compare long-term clinical outcomes between two procedures, especially on chronic residual shunt, late or very late procedure-related complications, and regression of pulmonary hypertension and left ventricular dilation. A total 255 patients having isolated PDA with a minimal diameter of >or= 4 mm treated from January 2000 to July 2003 were included in this study and have been followed up until July 2008. The patients were assigned to either the device or surgical closure group according to the patients' and/or their parents' preference. Baseline physical exams, chest roentgenography, electrocardiography, and echocardiography were performed preprocedure and at each follow-up. Seventy-two patients accepted the transcatheter procedure (Group-TC) and 183 underwent surgical operation (Group-SO) for PDA closure, both groups were similar in their demographics and preoperative clinical characteristics. There were no cardiac deaths and late complications such as infectious endocarditis and Amplatzer duct occluder (ADO) dislodge in either group. More acute procedure-related complications were recorded in Group-SO (13.7%) compared with Group-TC (1.4%) (P = 0.004). The recovery time was (8.7 +/- 2.3) days for the Group-SO and (1.3 +/- 0.5) days for the Group-TC (P ventricular dilation; neither survival freedom from pulmonary hypertension nor abnormal left ventricular end-diastolic volume index were significantly different between the surgical group and the Amplatzer group. Our study confirmed the long-term safety and efficacy of transcatheter Amplatzer occlusion. In comparison to the time-proven surgical closure, transcatheter Amplatzer occlusion was less invasive and associated with fewer complications and residual shunt, and as effective in the regression of pulmonary hypertension and left ventricular

    Substantial residual cardiovascular risks remain despite intensive statin treatment. Residual risks with high triglyceride and low high-density lipoprotein cholesterol are not the primary targets of statins. K-877 (pemafibrate) demonstrated robust efficacy on triglycerides and high-density lipoprotein cholesterol and a good safety profile as a monotherapy. The aim of these studies was to evaluate the efficacy and safety of K-877 add-on therapy to treat residual hypertriglyceridaemia during statin treatment. The objectives were investigated in two, multicentre, randomised, double-blind, placebo-controlled, parallel group comparison clinical trials: (A) K-877 0.1, 0.2, and 0.4 mg/day in combination with pitavastatin for 12 weeks in 188 patients, (B) K-877 0.2 (fixed dose) and 0.2 (0.4) (conditional up-titration) mg/day in combination with any statin for 24 weeks in 423 patients. In both studies, we found a robust reduction in fasting triglyceride levels by approximately 50% in all combination therapy groups, which was significant compared to the statin-monotherapy (placebo) groups (p statin-monotherapy groups without any noteworthy event in both studies. These results strongly support the favourable benefit-to-risk ratio of K-877 add-on therapy in combination with statin treatment. Copyright © 2017 The Authors. Published by Elsevier B.V.

    Simulation education is a learning method for improving self-efficacy and critical thinking skills. However, not much study has been done on how to use it for education on emergency cardiac arrest situations, for which a multidisciplinary team approach is required. This study investigated the effects of simulation education on nursing students' self-efficacy and critical thinking skills in emergency cardiac arrest situations. A quasi-experimental research approach with a crossover design was used to compare two types of simulation instruction methods. This study was conducted with 76 nursing students divided into two groups by order of instruction methods, in November and December 2016. Both groups of participants experienced a simulation lesson based on the same emergency scenario. Group A first completed a roleplay of an emergency cardiac arrest situation in a clinical setting, while Group B first listened to a lecture on the procedure. After ten days, Group A repeated the simulation exercise after listening to the lecture, while Group B completed the simulation exercise after the roleplay. The students' self-efficacy and critical thinking skills were measured using a questionnaire before and after each session. In the first session, self-efficacy and critical thinking skills scores increased greatly from pretest to posttest for Group A in comparison to Group B; no statistically significant difference was found between the two groups. In the second session, Group B showed a significant increase between pretest and posttest, while Group A showed no significant difference. Conducting the simulation exercise after the roleplay was a more effective teaching method than conducting it after the lecture. Moreover, having the nursing students assume various roles in realistic roleplay situations combined with simulation exercises led to a deeper understanding of clinical situations and improved their self-efficacy and critical thinking skills.

    To determine whether the tumour necrosis factor-alpha (TNF-alpha) antagonist adalimumab (Humira) can be efficacious after secondary loss of efficacy (i.e. loss of clinical response in patients who had initially demonstrated clinical response) to infliximab (Remicade) or etanercept (Enbrel). We studied 36 patients from the Stockholm TNF-alpha follow-up registry (STURE) who received adalimumab after secondary loss of efficacy to infliximab (group A, n = 27) or etanercept (group B, n = 9), and 26 patients who were started on adalimumab as the first TNF-alpha antagonist (group C). In group A, the baseline disease activity score 28 (DAS28) at infliximab institution was 5.5+/-0.2. During infliximab treatment, the mean best DAS28 was 3.7+/-0.2 (p<0.001), but increased to 5.2+/-0.3 when infliximab was stopped. After 3 months on adalimumab, the mean DAS28 decreased to 4.5+/-0.3 (p<0.003), and then to 4.2+/-0.2 at 6 months (p<0.001). In group B, the baseline DAS28 at etanercept institution was 6.6+/-0.5. During etanercept treatment, the mean best DAS28 was 4.6+/-0.5 (p<0.01), but increased to 5.7+/-0.4 by the time etanercept was stopped. After 3 months on adalimumab, the mean DAS28 decreased to 4.8+/-0.3 (p<0.005), and to 4.1+/-0.2 at 6 months (p<0.001). In group C, the mean baseline DAS28 was 5.6+/-0.3. After 6 months of adalimumab therapy, the DAS28 decreased to 3.5+/-0.4 (p<0.001). ACR20 responses with adalimumab in groups A, B, and C were similar (70-78%). For patients with secondary loss of efficacy from infliximab or etanercept, switching to adalimumab can restore a good clinical response.

    Several preclinical and clinical studies with the first commercially available highly concentrated Gd-chelate gadobutrol (1 mol/l) are reviewed. Physicochemical, pharmacological, and pharmacokinetic properties, safety analysis, as well as experimental and clinical efficacy studies are highlighted in comparison with 0.5-M Gd-chelates. The 1-mol gadobutrol has been proven to be safe in an examined dose range from 0.04 up to 0.5 mmol/kg body weight (b.w.). Even in patients with chronic renal impairment, including hemodialysis, gadobutrol can safely be applied at doses up to 0.3 mmol/kg b.w. For contrast-enhanced MRI in the equilibrium phase, efficacy data analysis shows comparable results to other commercially available extracellular Gd-chelates with lower Gd-concentrations (0.5 M). Studies focused on the potential benefit of a tighter bolus, such as brain perfusion imaging using T2*-effects, document the superiority of a highly concentrated Gd contrast agent. For contrast-enhanced MRA, clinical studies are still ongoing; therefore, the ultimate potential of a more compact bolus, using 1-M Gd-chelates, for contrast-enhanced MRI, has still to be analyzed, especially for time-resolved magnetic resonance angiography.

    In undergraduate medical education there is a trend away from ward-based teaching towards out-patient and community-based teaching. To study the potential effects of this altered emphasis on student learning, a pilot group of final-year medical students at the University of Dundee was asked to keep individual structured log-books. These contained details of patients seen during their 3-week orthopaedic attachment in both a ward and out-patient setting. A comparison of perceived learning in the two settings showed that students learned more from attending an out-patient clinic than a ward round, but did not make full use of the learning potential of either. The setting did not particularly influence the balance of learning as categorized here but only the ward round supplied experience of surgical complications. The amount of learning taking place in an out-patient clinic was influenced by student ability, measured by examination performance, but not by clinic work-load. The implications of increased use of out-patient clinics and the advantages and disadvantages of the approach employed are discussed. It is concluded that in the situation studied student learning in the outpatient setting is as good as or superior to the ward setting but should not totally replace it.

    Transcutaneous electrical nerve stimulation (TENS) is a nonpharmacological treatment for control of pain. It has come under much scrutiny lately with the Center for Medicare Services rendering a recent decision stating that "TENS is not reasonable and necessary for the treatment of CLBP [chronic low back pain]." When reading and analyzing the existing literature for which systematic reviews show that TENS is inconclusive or ineffective, it is clear that a number of variables related to TENS application have not been considered. Although many of the trials were designed with the highest of standards, recent evidence suggests that factors related to TENS application need to be considered in an assessment of efficacy. These factors include dosing of TENS, negative interactions with long-term opioid use, the population and outcome assessed, timing of outcome measurement, and comparison groups. The purpose of this perspective is to highlight and interpret recent evidence to help improve the design of clinical trials and the efficacy of TENS in the clinical setting.

    Clinical evaluation of TANDEM PSA which is the most frequently used prostate specific antigen (PSA) assay method in the world and a comparison with other methods were performed in Japanese cases in a cooperative research fashion. The minimum detectable level of the method was found to be 0.50 ng of PSA in one ml of serum and 1.9 ng/ml was regarded as the upper normal value in Japanese males. The distribution of serum PSA showed a significant difference between the benign prostate hypertrophy (BPH) cases and patients with stage C or D prostate cancer. The sero-diagnosis prostate cancer at an early stage with the TANDEM PSA was difficult. The correlation to other methods of PSA detection was very high. Furthermore, the clinical use of the method in following-up the clinical course of prostate cancer patients was very useful. These findings suggested that the PSA detection using TANDEM PSA is applicable even in Japanese cases although the upper cut-off level is decreased.

    The monoamine oxidase B inhibitors selegiline and rasagiline have not been compared in head-to-head clinical trials in patients with early Parkinson's disease.  The aim of this review was to compare the efficacy of these two agents in this setting. Randomized, placebo-controlled trials with an endpoint of the mean change from baseline in the Unified Parkinson's Disease Rating Scale (UPDRS) total score were included. Analysis included calculation of the standardized mean differences (SMDs) with 95% confidence intervals (CIs) and Forest Plot analyses for comparisons of pooled results. Five studies with selegiline (n = 1029) and four with rasagiline (n = 820) were included. Treatment duration was 2.5-9 months. Both selegiline and rasagiline showed significant SMDs versus placebo (-0.690, 95% CI -0.811, -0.569 and -1.025, 95% CI -1.230, -0.820; respectively), indicating a significant effect of both drugs on UPDRS. The SMD between selegiline and rasagiline was not significantly different (SMD 0.079; 95% CI -0.010, +0.167). It appears that selegiline and rasagiline have comparable efficacy in improving Parkinsonian symptoms in patients with early stage disease.

    Norway spruce (Picea abies) produces resin to protect against decomposition by microbial pathogens. In vitro tests have shown that spruce resin has antifungal properties against dermatophytes known to cause nearly 90% of onychomycosis in humans. To confirm previous in vivo observations that a topical resin lacquer provides mycological and clinical efficacy, and to compare this lacquer with topical amorolfine hydrochloride lacquer and systemic terbinafine for treating dermatophyte toenail onychomycosis. In this prospective, randomized, controlled, investigator-blinded study, 73 patients with onychomycosis were randomized to receive topical 30% resin lacquer once daily for 9 months, topical 5% amorolfine lacquer once weekly for 9 months, or 250 mg oral terbinafine once daily for 3 months. The primary outcome measure was complete mycological cure at 10 months. Secondary outcomes were clinical efficacy, cost-effectiveness and patient compliance. At 10 months, complete mycological cure rates with the resin, amorolfine and terbinafine treatments were 13% [95% confidence interval (CI) 0-28], 8% (95% CI 0-19) and 56% (95% CI 35-77), respectively (P ≤ 0·002). At 10 months, clinical responses were complete in four patients (16%) treated with terbinafine, and partial in seven (30%), seven (28%) and nine (36%) patients treated with resin, amorolfine and terbinafine, respectively (P terbinafine treatments cost €41·6, €56·3 and €52·1, respectively, per patient (P terbinafine was significantly more effective in terms of mycological cure and clinical outcome than either topical therapy at the 10-month follow-up. © 2015 British Association of Dermatologists.

    Tension type headache in both its forms, episodic and chronic, is the most common type of headache experienced by the population. The headache attack or the prevention of new crises may be treated with pharmacological as well as non-pharmacological measures. This study included 5,490 patients from out-patient clinics and medical offices covering various regions of Brazil. Approximately 95% of the subjects had episodic tension type headache, while 5% had chronic tension type headache. The majority of the patients presented with crisis of moderate intensity (62.19%). In 5,419 patients a tension type headache crisis was treated with acetaminophen 1000 mg and caffeine 130 mg. In 93.98%, onset of relief occurred within 2 hours of taking the medication. In 77.61%, complete reversion of the crisis occurred within 2 hours. Good/excellent efficacy ratings were achieved in 61.93%/37.80% of the cases according to the physician's assessment and in 48.51%/40.29% according to the patients' assessment. Adverse events, commonly gastrointestinal manifestations, were reported by 5.57% of the patients. This is a Brazilian study of the efficacy and safety of the combined use of acetaminophen-caffeine for the treatment of tension type headache.

    Platelet-rich plasma (PRP) which contains large amounts of growth factors has been tried to enhance therapeutic efficacy of laser treatment for acne scar with unknown underlying mechanism. The present study was conducted to investigate the molecular mechanism of increased clinical efficacy of PRP when combined with fractional laser treatment for treating acne scars. Subjects with mild to moderate acne scars were treated with two sessions of fractional CO 2 laser therapy given with and without co-administration of PRP. Skin biopsy specimens were obtained at baseline, 1, 3, 7, and 28 days for investigation of molecular profiles associated with skin changes produced by laser plus PRP treatment. The PRP treatment increased clinical efficacy with decreased severity of adverse effects such as erythema, swelling and oozing. Productions of TGFβ1 and TGFβ3 proteins were more highly elevated on the PRP-treated side of the face compared to the control side at day 28. Furthermore, PRP-treated side showed significant increase of c-myc, TIMP, and HGF expression. Experimental fibroblast culture model was also used. PRP administration after laser irradiation increased expressions of p-Akt, TGFβ1, TGFβ3, β-catenin, collagen 1, and collagen 3 in both dose-dependent and time dependent manners in fibroblast. Moreover, we acquired clinical and histological data through randomized control clinical trial. Taken together with human study results combined with the data from cell experiments we suggest that PRP treatment increased fibrogenetic molecules induced by fractional CO 2 laser, which have association with clinical effect.

    The aim of this study was to compare the clinical efficacies of naproxen sodium-codeine phosphate in combination, benzydamine hydrochloride, and diclofenac potassium for pain, edema, and trismus after lower third molar extraction. Ninety healthy volunteers in whom impacted third molar extraction was indicated were randomly distributed into 3 groups. One hour before the tooth-extraction process, patients were administered one of the following drugs: naproxen sodium, 550 mg, and codeine phosphate, 30 mg, in a tablet; diclofenac potassium, 50 mg, in a coated pill; or benzydamine hydrochloride, 50 mg, in a coated pill. Pain assessment was conducted via a visual analog scale; edema assessment, by measuring the distances between predetermined facial landmarks; and trismus assessment, by measuring interincisal distance. Regarding rescue analgesics (paracetamol, 500 mg), the number and time of use by patients were recorded. Naproxen sodium-codeine phosphate was more effective for pain, edema, and trismus than diclofenac potassium and benzydamine hydrochloride (P hydrochloride yielded similar clinical responses to diclofenac potassium (P > .05). No drug-related side effects were observed. Naproxen sodium-codeine phosphate constitutes the drug of choice after the extraction of a patient's impacted lower third molar. Benzydamine hydrochloride has similar efficacy to diclofenac potassium, and it can be used as a nonsteroidal anti-inflammatory analgesic drug.

    Secondary pharmaceutical measures are effective in all age groups for the prevention of osteoporotic fractures. This prospective study determines the demographics of 566 consecutive osteoporotic hip fractures presenting to a Level 1 Trauma Center. We examine the efficacy of simple treatment recommendations for pharmaceutical treatment of osteoporosis and the factors determining general practitioner and patient compliance with these recommendations in a community setting. One out of four patients (24.5%) had sustained a previous fragility fracture. Mean age was 80 years. Twenty five percent were resident in a nursing home and only 10% were taking anti-resorptive therapy preoperatively. In hospital mortality was 6%, and 39% of recruited patients were dead at 12 months. By this time more than half the survivors were resident in a nursing home. The compliance with anti-resorptive therapy had increased to over 70% consequent to our simple recommendations. Significant differences in GP and patient compliance were observed between nursing home and own residence dwellers. This study demonstrates the efficacy of a simple clinical practice intervention in increasing patient and GP compliance with secondary fracture prevention measures. We also discuss many of the confounding issues determining this compliance.

    Full Text Available Abstract Background Older patients are typically underrepresented in clinical trials of medications for chronic pain. A post hoc analysis of multiple clinical studies of pregabalin in patients with painful diabetic peripheral neuropathy (DPN or postherpetic neuralgia (PHN was conducted to evaluate the efficacy and safety of pregabalin in older patients. Methods Data from 11 double-blind, randomized, placebo-controlled clinical studies of pregabalin in patients with DPN or PHN were pooled. Efficacy outcomes included change in Daily Pain Rating Scale score, ≥30% and ≥50% responders, and endpoint pain score ≤3. Safety was based on adverse events (AEs. Primary efficacy was analyzed by analysis of covariance with terms for treatment, age category, protocol, baseline pain, and treatment-by-age category interaction. Results 2516 patients (white, n = 2344 [93.2%]; men, n = 1347 [53.5%]; PHN, n = 1003 [39.9%]; pregabalin, n = 1595 were included in the analysis. Patients were grouped by age: 18 to 64 years (n = 1236, 65 to 74 years (n = 766, and ≥75 years (n = 514. Baseline mean pain and sleep interference scores were comparable across treatment and age groups. Significant improvements in endpoint mean pain were observed for all pregabalin dosages versus placebo in all age groups (p ≤ 0.0009, except for the lowest dosage (150 mg/day in the youngest age group. Clinically meaningful pain relief, defined as ≥30% and ≥50% pain response, was observed in all age groups. The most common AEs were dizziness, somnolence, peripheral edema, asthenia, dry mouth, weight gain, and infections. The relative risks for these AEs increased with pregabalin dose, but did not appear related to older age or type of neuropathic pain. Conclusions Pregabalin (150-600 mg/day significantly reduced pain in older patients (age ≥65 years with neuropathic pain and improvements in pain were comparable to those observed in younger patients.

    Full Text Available Cutaneous leishmaniasis (CL represents a range of skin diseases caused by infection with Leishmania parasites and associated with tissue inflammation and skin ulceration. CL is clinically widespread in both the Old and New World but lacks treatments that are well tolerated, effective and inexpensive. Oleylphosphocholine (OlPC is a new orally bioavailable drug of the alkylphosphocholine family with potent antileishmanial activity against a broad range of Leishmania species/strains.The potential of OlPC against Old World CL was evaluated in a mouse model of Leishmania (L. major infection in BALB/c mice. Initial dose-response experiments showed that an oral daily dose of 40 mg/kg of OlPC was needed to impact time to cure and lesion sizes. This dose was then used to directly compare the efficacy of OlPC to the efficacy of the antileishmanial drugs miltefosine (40 mg/kg/day, fluconazole (160 mg/kg/day and amphotericin B (25 mg/kg/day. OlPC, miltefosine and fluconazole were given orally for 21 days while amphotericin B was administered intraperitoneally for 10 days. Ulcer sizes and animal weights were followed up on a weekly basis and parasitemia was determined by means of a real-time in vivo imaging system which detects luminescence emitted from luciferase-expressing infecting L. major parasites. Amphotericin B and OlPC showed excellent efficacy against L. major lesions in terms of reduction of parasitic loads and by inducing complete healing of established lesions. In contrast, treatment with miltefosine did not significantly affect parasitemia and lesion sizes, while fluconazole was completely ineffective at the dose regimen tested.Given the data showing the outstanding efficacy and tolerability of OlPC, our results suggest that OlPC is a promising new drug candidate to improve and simplify current clinical management of L. major CL.

    Post-Market Research Clinical evidence supports the use of dexketoprofen trometamol (DEX) to manage acute postoperative pain. However, controversies surround the impact of the use of this drug in preoperative analgesic protocols. The aim of the present meta-analysis was to evaluate the effectiveness of the preoperative administration of DEX under postoperative pain conditions. Electronic and manual searches were conducted through diverse electronic databases. A systematic review and meta-analysis to evaluate the analgesic efficacy of the preoperative administration of DEX was performed including Randomized Clinical Trials (RCTs) published between 2002 and 2017. Suitable individual studies were evaluated through a quality system, and the data were extracted and analyzed. Fourteen RTCs were included (12 parallel trials and 2 cross-over trials), published in the English and Turkish languages. Follow-up periods ranged from 4, 6, 8, 24, and 48 hr. All trials measured the outcome result as Acute Pain Level (APL) (VAS, NRS, VRS), time to requiring a second dose of DEX or analgesic emergency and consumption of opioids via patient-controlled analgesia. When the comparators were other drugs - paracetamol, Lornoxicam or placebo during the preoperative time, preoperative administration of DEX was superior. When the comparison comprised preoperative and postoperative DEX, both alternatives exhibited comparable analgesic effects. The analgesic efficacy of the preoperative administration of DEX when compared to placebo, lornoxicam, and paracetamol on postoperative pain was evident. Preoperative administration of DEX compared to its immediate postoperative administration showed a similar analgesic effect. © 2017 Wiley Periodicals, Inc.

    Management of alopecia areata (AA) and androgenetic alopecia (AGA) is often challenging. The use of carboxytherapy may be a novel therapeutic option for such cases. To evaluate the clinical efficacy and safety of carboxytherapy in alopecia areata and androgenetic alopecia. This study was conducted on 80 patients with alopecia divided into two groups; Group I included 40 AA patients (Group IA received carboxytherapy and Group IB control received placebo), and Group II included 40 AGA patients (Group IIA received carboxytherapy and Group IIB control received placebo), and followed up monthly for 3 months. They were evaluated clinically (by assessment of Severity of Alopecia Tool (SALT) score in group I, and Sinclair scale and Norwood-Hamilton scale in group II), by dermoscopy and digital dermoscopy at each visit. Group IA patients showed significant clinical improvement in SALT score and dermoscopic improvement after carboxytherapy and at the end of follow-up period with significant reduction in dystrophic hair, black dots, yellow dots, and tapered hair coinciding with significant emergence of regrowing hair. Group IIA patients showed significant clinical and dermoscopic improvement after carboxytherapy with significant increase in hair density measured by digital dermoscopy. However, regression of these results was observed during the follow-up period but was still significantly better than before treatment. There were statistically significant improvements in clinical score, global assessments, dermoscopic, and digital dermoscopic findings in both group IA and group IIA received carboxytherapy in comparison with group IB and group IIB received placebo injections, respectively. Carboxytherapy seems to be a promising therapeutic option for patchy AA and could be helpful as an adjuvant therapy of AGA but more than 6 sessions are required and adjuvants are recommended for maintenance of the results. © 2018 Wiley Periodicals, Inc.

    Full Text Available Aim: In the present study, a therapeutic trial was conducted to assess comparative efficacy of crystalloid plus colloid and crystalloid intravenous infusions alone as fluid therapy in dogs suffering from hemorrhagic gastroenteritis (HGE. Materials and Methods: 20 dogs manifesting HGE, presented at Teaching Veterinary Clinical Services Complex, Ludhiana, Punjab, were selected randomly for the trial. All of them were observed to suffer from moderate dehydration on clinical examination. Crystalloids 5% DNS and RL were used in combination with polygelin 3.5% colloidal solution in the first group (Combination I and in the second group, the afore-said crystalloids (Combination II were used, both groups consisting of 10 cases each. Antibiotics and symptomatic treatment were same for all the 20 cases. The outcome of both treatment groups was evaluated on hemato-biochemical parameters, before and after administration of the therapies and compared statistically within and between the two groups. Hemato-biochemical parameters of eight clinically healthy animals were considered as control for comparison. Result: On hemato-biochemical examination, significant alterations were observed in leucogram, platelet and serum globulin concentration after the treatment in the first group as compared to before treatment values. In the second group, mean hemoglobin varied significantly after the treatment. After therapies were administered, significant difference in serum globulin level and albumin: Globulin was found in between the treatment groups (Combination I and Combination II. Clinical recovery was faster in the first group than the second group of animals. Conclusion: On hemodynamic and laboratory data, efficacies of both the fluid therapies were equivocal. Colloidal solutions may hasten recovery in small animals suffering from gastrointestinal crisis.

    The treatment of type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) using insulin is not ideal at this time. Despite advances made with basal insulin analogues, many individuals achieve less than optimal glycemic control or are at risk for hypoglycemia. Currently available basal insulin analogues do not deliver steady, peakless, continuous insulin for >24 hours and are associated with adverse events, including hypoglycemia. The objective of this paper was to review the clinical efficacy and safety of upcoming long-acting insulin analogues such as insulin degludec and insulin glargine 300 U/mL (Gla-300). A comprehensive literature search of PubMed and Google Scholar was conducted from 1966 to 2015. The search included randomized controlled trials that specifically assessed the efficacy and safety of insulin degludec and Gla-300 in patients with T1DM and T2DM. The efficacy of insulin degludec and Gla-300 in achieving glycemic control has been reported in clinical trials in adults with T1DM and T2DM. Not only did a large number of patients succeed in meeting glycosylated hemoglobin targets, but they also experienced reductions in hypoglycemic events. These 2 therapies are associated with a reduced risk of nocturnal hypoglycemia and are generally well tolerated. The long-acting insulin analogues insulin degludec and Gla-300 are promising therapies in the treatment of T1DM and T2DM. Their improved insulin delivery for >24 hours offers glycemic control with a good safety profile. Copyright © 2017 Elsevier HS Journals, Inc. All rights reserved.

    Vonoprazan is a novel potassium-competitive acid blocker which may provide clinical benefit in acid-related disorders. To verify the non-inferiority of vonoprazan vs. lansoprazole in patients with erosive oesophagitis (EE), and to establish its long-term safety and efficacy as maintenance therapy. In this multicentre, randomised, double-blind, parallel-group comparison study, patients with endoscopically confirmed EE (LA Classification Grades A-D) were randomly allocated to receive vonoprazan 20 mg or lansoprazole 30 mg once daily after breakfast. The primary endpoint was the proportion of patients with healed EE confirmed by endoscopy up to week 8. In addition, subjects who achieved healed EE in the comparison study were re-randomised into a long-term study to investigate the safety and efficacy of vonoprazan 10 or 20 mg as maintenance therapy for 52 weeks. Of the 409 eligible subjects randomised, 401 completed the comparison study, and 305 entered the long-term maintenance study. The proportion of patients with healed EE up to week 8 was 99.0% for vonoprazan (203/205) and 95.5% for lansoprazole (190/199), thus verifying the non-inferiority of vonoprazan (P lansoprazole in EE was verified in the comparison study, and vonoprazan was well-tolerated and effective during the long-term maintenance study. © 2015 The Authors.

    Because of the rapidly growing use of ultrasound shear wave elastography (SWE) in clinical practices, there is a significant need for development of clinical physics performance assessment methods for this technology. This study aims to report two clinical medical physicists' tasks: (a) acceptance testing (AT) of SWE function on ten commercial ultrasound systems for clinical liver application and (b) comparison of SWE measurements of targets across vendors for clinical musculoskeletal application. For AT, ten GE LOGIQ E9 XDclear 2.0 scanners with ten C1-6-D and ten 9L-D transducers were studied using two commercial homogenous phantoms. Five measurements were acquired at two depths for each scanner/transducer pair by two operators. Additional tests were performed to access effects of different coupling media, phantom locations and operators. System deviations were less than 5% of group mean or three times standard deviation; therefore, all systems passed AT. A test protocol was provided based on results that no statistically significant difference was observed between using ultrasound gel and salt water for coupling, among different phantom locations, and that interoperator and intraoperator coefficient of variation was less than 3%. For SWE target measurements, two systems were compared - a Supersonic Aixplorer scanner with a SL10-2 and a SL15-4 transducer, and an abovementioned GE scanner with 9L-D transducer. Two stepped cylinders with diameters of 4.05-10.40 mm were measured both longitudinally and transaxially. Target shear wave speed quantification was performed using an in-house MATLAB program. Using the target shear wave speed deduced from phantom specs as a reference, SL15-4 performed the best at the measured depth. However, it was challenging to reliably measure a 4.05 mm target for either system. The reported test methods and results could provide important information when dealing with SWE-related tasks in the clinical environment. © 2018 The Authors

    A clinical field investigation was conducted to evaluate the safety and efficacy of 10% imidacloprid/2.5% moxidectin for the treatment of ear mites (Otodectes cynotis) in dogs. The study was a multi-centered, blinded, positive controlled, randomized clinical trial conducted under field conditions with privately owned pets. A total of 17 veterinary clinics enrolled cases for the study. An otoscopic examination was performed to confirm the presence of O. cynotis residing in the ear of the dog prior to enrollment. A single-dog household was enrolled in the study if the dog had 5 or more ear mites and an acceptable physical examination. A multi-dog household was eligible if at least one dog in the household had 5 or more mites and all dogs in the household had acceptable physical exams and met the inclusion criteria. Qualified households were randomly assigned to treatments to receive either 10% imidacloprid+2.5% moxidectin topical solution or topical selamectin solution (positive control product) according to a pre-designated enrollment ratio of 2:1, respectively. If more than one dog in a multiple dog household had adequate numbers of ear mites, one dog was randomly selected to represent the household for efficacy evaluation prior to treatment. Treatments were administered twice per label and dose banding directions for each product approximately 28 days apart (Days 0 and 28), by the dog's owner at the study site. All dogs in a household were treated on the same day and with the same product. The owners completed a post-treatment observation form one day after each treatment. Post-treatment otoscopic examinations were performed by the investigators or attending veterinarian on Days 28 and 56. Physical examinations were performed on Days 0 and 56. One hundred and four (104) households were evaluated for efficacy on SD 28, and 102 households were evaluated for efficacy on SD 56. The dogs' ages ranged from 2 months to 16 years.

    Full Text Available The objective of this study was to assess the efficacy and safety of electroacupuncture in 138 patients with earthquake-caused PTSD using Randomized Controlled Trials (RCTs. 138 cases enrolled were randomly assigned to an electro-acupuncture group and a paroxetine group. The electro-acupuncture group was treated by scalp electro-acupuncture on Baihui (GV 20, Sishencong (EX-HN 1, Shenting (GV 24, and Fengchi (GB 20, and the paroxetine group was treated with simple oral administration of paroxetine. The efficacy and safety of the electro-acupuncture on treatment of 69 PTSD patients were evaluated using Clinician-Administered PTSD Scale (CAPS, Hamilton Depression Scale (HAMD, Hamilton Anxiety Scale (HAMA, and Treatment Emergent Symptom Scale (TESS according to clinical data. The total scores of CAPS, HAMD, and HAMA in the two groups after treatment showed significant efficacy compared to those before treatment. The comparison of reduction in the scores of CAPS, HAMD, and HAMA between the two groups suggested that the efficacy in the treated group was better than that in the paroxetine group. The present study suggested that the electro-acupuncture and paroxetine groups have significant changes in test PTSD, but the electro-acupuncture 2 group was more significant.

  19. A behavior-analytic critique of Bandura's self-efficacy theory

    Science.gov (United States)

    Biglan, Anthony

    1987-01-01

    A behavior-analytic critique of self-efficacy theory is presented. Self-efficacy theory asserts that efficacy expectations determine approach behavior and physiological arousal of phobics as well as numerous other clinically important behaviors. Evidence which is purported to support this assertion is reviewed. The evidence consists of correlations between self-efficacy ratings and other behaviors. Such response-response relationships do not unequivocally establish that one response causes another. A behavior-analytic alternative to self-efficacy theory explains these relationships in terms of environmental events. Correlations between self-efficacy rating behavior and other behavior may be due to the contingencies of reinforcement that establish a correspondence between such verbal predictions and the behavior to which they refer. Such a behavior-analytic account does not deny any of the empirical relationships presented in support of self-efficacy theory, but it points to environmental variables that could account for those relationships and that could be manipulated in the interest of developing more effective treatment procedures.

    The objective of this analysis was to evaluate the efficacy and safety of oritavancin compared with vancomycin for patients with acute bacterial skin and skin structure infections (ABSSSIs) who received treatment in the outpatient setting in the Phase 3 SOLO clinical trials. SOLO I and SOLO II were 2 identically designed comparative, multicenter, double-blind, randomized studies to evaluate the efficacy and safety of a single 1200-mg dose of intravenous (IV) oritavancin versus 7-10 days of twice-daily IV vancomycin for the treatment of ABSSSI. Protocols were amended to allow enrolled patients to complete their entire course of antimicrobial therapy in an outpatient setting. The primary efficacy outcome was a composite endpoint (cessation of spread or reduction in size of the baseline lesion, absence of fever, and no rescue antibiotic at early clinical evaluation [ECE]) (48 to 72 hours). Key secondary endpoints included investigator-assessed clinical cure 7 to 14 days after end of treatment (posttherapy evaluation [PTE]) and 20% or greater reduction in lesion area at ECE. Safety was assessed until day 60. Seven hundred ninety-two patients (oritavancin, 392; vancomycin, 400) received entire course of treatment in the outpatient setting. Efficacy response rates at ECE and PTE were similar (primary composite endpoint at ECE: 80.4% vs 77.5% for oritavancin and vancomycin, respectively) as was incidence of adverse events. Five patients (1.3%) who received oritavancin and 9 (2.3%) vancomycin patients were subsequently admitted to a hospital. Oritavancin provides a single-dose alternative to multidose vancomycin for treatment of ABSSSI in the outpatient setting. © The Author 2017.
