Modified-release (MR oral prednisone taken at bedtime has been shown to be more effective than immediate-release prednisone taken in the morning. The efficacy of low-dose MR prednisolone in patients with SpA is unknown. Patients and methods: This single-center cohort study retrospectively assessed the effectiveness and safety of 12-week low-dose MR prednisone (5 mg daily, bedtime administration in GC-naïve adult patients with symptomatic axial SpA. A 50% improvement of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI or a final BASDAI score of <4 according to disease activity at baseline was chosen as the primary outcome parameter after MR prednisone. Results: Fifty-seven patients were evaluated; of them, 41 had an active disease (BASDAI score of ≥4 at baseline. MR prednisone significantly reduced BASDAI (from 5.5±2.6 to 3.0±2.8, P<0.001 as well as inflammatory symptoms, pain, fatigue and morning stiffness. The overall response rate after MR prednisone was 52.6% (53.7% in patients with active SpA and 50.0% in patients with low-active disease; nonsignificant. At multivariable analysis, none of the considered clinical findings independently predicted the response to MR prednisone in subjects with active SpA. Overall, seven patients (11.8% had nonserious adverse drug reactions after MR prednisone

    Efavirenz (EFV) is a nonnucleoside reverse transcriptase inhibitor approved worldwide for the treatment of HIV in adults and children over 3 years of age or weighing over 10 kg. Only recently EFV was approved in children over 3 months and weighing at least 3.5 kg in the United States and the European Union. The objective of this analysis was to support the selection of an appropriate dose for this younger pediatric population and to explore the impact of CYP2B6 genetic polymorphisms on EFV systemic exposures. A population pharmacokinetic (PPK) model was developed using data from three studies in HIV-1-infected pediatric subjects (n = 168) and one study in healthy adults (n = 24). The EFV concentration-time profile was best described by a two-compartment model with first-order absorption and elimination. Body weight was identified as a significant predictor of efavirenz apparent clearance (CL), oral central volume of distribution (VC), and absorption rate constant (Ka). The typical values of efavirenz apparent CL, VC, oral peripheral volume of distribution (VP), and Ka for a reference pediatric patient were 4.8 liters/h (4.5 to 5.1 liters/h), 84.9 liters (76.8 to 93.0 liters), 287 liters (252.6 to 321.4 liters), and 0.414 h(-1) (0.375 to 0.453 h(-1)), respectively. The final model was used to simulate steady-state efavirenz concentrations in pediatric patients weighing <10 kg to identify EFV doses that produce comparable exposure to adult and pediatric patients weighing ≥10 kg. Results suggest that administration of EFV doses of 100 mg once daily (QD) to children weighing ≥3.5 to <5 kg, 150 mg QD to children weighing ≥5 to <7.5 kg, and 200 mg QD to children weighing ≥7.5 to <10 kg produce exposures within the target range. Further evaluation of the impact of CYP2B6 polymorphisms on EFV PK showed that the identification of CYP2B6 genetic status is not predictive of EFV exposure and thus not informative to guide pediatric dosing regimens.

  7. Paliperidone Palmitate Intramuscular 3-Monthly Formulation: A Review in Schizophrenia.

    Lamb, Yvette N; Keating, Gillian M

    2016-10-01

    A 3-monthly formulation of intramuscular paliperidone palmitate (3-monthly paliperidone palmitate) has recently been approved for the maintenance treatment of schizophrenia in adult patients in the EU (Trevicta(®)), following earlier approval in the USA (Invega Trinza(®)). This narrative review discusses the clinical use of 3-monthly paliperidone palmitate in the maintenance treatment of schizophrenia in adult patients and summarizes its pharmacological properties. The efficacy of the 3-monthly paliperidone palmitate formulation as a maintenance treatment for schizophrenia has been demonstrated in well designed, phase III trials. Three-monthly paliperidone palmitate was more effective than placebo in delaying time to relapse and reducing relapse rates, and was noninferior to 1-monthly paliperidone palmitate in the proportion of patients that remained relapse-free. The 3-monthly formulation was also more effective than placebo in controlling the symptoms of schizophrenia, whilst not differing significantly from the 1-monthly formulation in terms of symptomatic control. Three-monthly paliperidone palmitate was generally well tolerated in clinical trials, with a tolerability profile consistent with that of the 1-monthly formulation. In conclusion, 3-monthly paliperidone palmitate is a useful treatment option for adult patients with schizophrenia who are adequately treated with the 1-monthly formulation, particularly for those who would prefer, or may benefit from, longer dosing intervals.

  13. Efficacy of clinical gait analysis: A systematic review.

    Wren, Tishya A L; Gorton, George E; Ounpuu, Sylvia; Tucker, Carole A

    2011-06-01

    The aim of this systematic review was to evaluate and summarize the current evidence base related to the clinical efficacy of gait analysis. A literature review was conducted to identify references related to human gait analysis published between January 2000 and September 2009 plus relevant older references. The references were assessed independently by four reviewers using a hierarchical model of efficacy adapted for gait analysis, and final scores were agreed upon by at least three of the four reviewers. 1528 references were identified relating to human instrumented gait analysis. Of these, 116 original articles addressed technical accuracy efficacy, 89 addressed diagnostic accuracy efficacy, 11 addressed diagnostic thinking and treatment efficacy, seven addressed patient outcomes efficacy, and one addressed societal efficacy, with some of the articles addressing multiple levels of efficacy. This body of literature provides strong evidence for the technical, diagnostic accuracy, diagnostic thinking and treatment efficacy of gait analysis. The existing evidence also indicates efficacy at the higher levels of patient outcomes and societal cost-effectiveness, but this evidence is more sparse and does not include any randomized controlled trials. Thus, the current evidence supports the clinical efficacy of gait analysis, particularly at the lower levels of efficacy, but additional research is needed to strengthen the evidence base at the higher levels of efficacy.

  14. Cardiometabolic Health in Submariners Returning from a 3-Month Patrol

    Heath G. Gasier

    2016-02-01

    Full Text Available Confined space, limited exercise equipment, rotating shift work and reduced sleep may affect cardiometabolic health in submariners. To test this hypothesis, 53 male U.S. Submariners (20–39 years were studied before and after a 3-month routine submarine patrol. Measures included anthropometrics, dietary and physical activity, biomarkers of cardiometabolic health, energy and appetite regulation, and inflammation. Before deployment, 62% of submariners had a body fat % (BF% ≥ 25% (obesity, and of this group, 30% met the criteria for metabolic syndrome. In obese volunteers, insulin, the homeostatic model assessment of insulin resistance (HOMA-IR, leptin, the leptin/adiponectin ratio, and pro-inflammatory chemokines growth-related oncogene and macrophage-derived chemokine were significantly higher compared to non-obese submariners. Following the patrol, a significant mean reduction in body mass (5% and fat-mass (11% occurred in the obese group as a result of reduced energy intake (~2000 kJ during the patrol; and, independent of group, modest improvements in serum lipids and a mean reduction in interferon γ-induced protein 10 and monocyte chemotactic protein 1 were observed. Since 43% of the submariners remained obese, and 18% continued to meet the criteria for metabolic syndrome following the patrol, the magnitude of weight loss was insufficient to completely abolish metabolic dysfunction. Submergence up to 3-months, however, does not appear to be the cause of obesity, which is similar to that of the general population.

  15. Path analysis of self-efficacy and diving performance revisited.

    Feltz, Deborah L; Chow, Graig M; Hepler, Teri J

    2008-06-01

    The Feltz (1982) path analysis of the relationship between diving efficacy and performance showed that, over trials, past performance was a stronger predictor than self-efficacy of performance. Bandura (1997) criticized the study as statistically "overcontrolling" for past performance by using raw past performance scores along with self-efficacy as predictors of performance. He suggests residualizing past performance by regressing the raw scores on self-efficacy and entering them into the model to remove prior contributions of self-efficacy imbedded in past performance scores. To resolve this controversy, we reanalyzed the Feltz data using three statistical models: raw past performance, residual past performance, and a method that residualizes past performance and self-efficacy. Results revealed that self-efficacy was a stronger predictor of performance in both residualized models than in the raw past performance model. Furthermore, the influence of past performance on future performance was weaker when the residualized methods were conducted.

  16. Painful Memories: Reliability of Pain Intensity Recall at 3 Months in Senior Patients

    2017-01-01

    Background. Validity of pain recall is questioned in research. Objective. To evaluate the reliability of pain intensity recall for seniors in an emergency department (ED). Methods. This study was part of a prospective multicenter project for seniors (≥65 years old) treated in an ED for minor traumatic injury. Pain intensity (0–10 numerical rating scale) was evaluated at the initial ED visit, at one week (baseline), and 3 months. At three months, patients were asked to recall the pain intensity they had at baseline. Results. 482 patients were interviewed (mean age 76.6 years, SD ± 7.3) and 72.8% were female. Intraclass correlation coefficient between pain at baseline and its recall was 0.24 (95% CI: 0.14–0.33). Senior patients tended to overestimate their pain intensity by a mean of 1.2 (95% CI: 0.9–1.5) units. A stepwise multiple regression analysis showed that the variance of baseline pain recall at 3 months was explained by pain at ED visit (11%), pain at 3 months (7%), and pain at baseline (2%). Conclusion. The accuracy of pain intensity recall after three months is poor in seniors and seems to be influenced by the pain experienced at the time of injury.

  17. Septic Arthritis in Infants Younger Than 3 Months: A Retrospective Review.

    Bono, Kenneth T; Samora, Julie Balch; Klingele, Kevin E

    2015-09-01

    Septic arthritis in infants is rare and can be difficult to diagnose. This study reviewed a series of patients younger than 3 months to identify factors that may assist in early diagnosis and treatment. A query of records at a large Midwestern pediatric hospital (1994-2010) was performed to identify all patients younger than 3 months at the time of diagnosis. Analysis included birth history, joint involvement, physical examination findings, laboratory results, imaging results, method of treatment, and outcome. In 14 cases (11 boys, 3 girls; mean age at diagnosis, 42.2 days), complete records were available for review. Involved joints included the knee, hip, and shoulder. The most common findings on physical examination were decreased range of motion (100%), tenderness (100%), and swelling (71.4%). Mean temperature was 38.5°C. Mean white blood cell count was 18.5 K/µL, mean erythrocyte sedimentation rate was 48.9 mm/h, and mean C-reactive protein level was 6.1 mg/dL. More than half (57.1%) of joint aspirates grew positive cultures, and 41.7% of blood cultures had positive results. Causative organisms were group B streptococcus, methicillin-sensitive Staphylococcus aureus, Haemophilus influenzae, Streptococcus pneumoniae, Salmonella enterica, and Candida albicans. The most common physical examination findings in infants younger than 3 months with septic arthritis include tenderness, decreased range of motion, and swelling. White blood cell count, C-reactive protein level, and erythrocyte sedimentation rate are likely to be elevated, but these findings should be used in combination with findings on physical examination and radiographic studies to aid in diagnosis.

  19. Off-hour effect on 3-month functional outcome after acute ischemic stroke: a prospective multicenter registry.

    Chulho Kim

    Full Text Available BACKGROUND AND PURPOSE: The time of hospital arrival may have an effect on prognosis of various vascular diseases. We examined whether off-hour admission would affect the 3-month functional outcome in acute ischemic stroke patients admitted to tertiary hospitals. METHODS: We analyzed the 'off-hour effect' in consecutive patients with acute ischemic stroke using multi-center prospective stroke registry. Work-hour admission was defined as when the patient arrived at the emergency department between 8 AM and 6 PM from Monday to Friday and between 8 AM and 1 PM on Saturday. Off-hour admission was defined as the rest of the work-hours and statutory holidays. Multivariable logistic regression was used to analyze the association between off-hour admission and 3-month unfavorable functional outcome defined as modified Rankin Scale (mRS 3-6. Multivariable model included age, sex, risk factors, prehospital delay time, intravenous thrombolysis, stroke subtypes and severity as covariates. RESULTS: A total of 7075 patients with acute ischemic stroke were included in this analysis: mean age, 67.5 (±13.0 years; male, 58.6%. In multivariable analysis, off-hour admission was not associated with unfavorable functional outcome (OR, 0.89; 95% CI, 0.72-1.09 and mortality (OR, 1.09; 95% CI, 0.77-1.54 at 3 months. Moreover, off-hour admission did not affect a statistically significant shift of 3-month mRS distributions (OR, 0.90; 95% CI, 0.78-1.05. CONCLUSIONS: 'Off-hour' admission is not associated with an unfavorable 3-month functional outcome in acute ischemic stroke patients admitted to tertiary hospitals in Korea. This finding indicates that the off-hour effects could be overcome with well-organized stroke management strategies.

  20. Efficacy of escitalopram compared to citalopram: a meta-analysis.

    Montgomery, Stuart; Hansen, Thomas; Kasper, Siegfried

    2011-03-01

    The aim of this review was to assess the clinical relevance of the relative antidepressant efficacy of escitalopram and citalopram by meta-analysis. Studies in major depressive disorder (MDD) with both escitalopram and citalopram treatment arms were identified. Adult patients had to meet DSM-IV criteria for MDD. The primary outcome measure was the treatment difference in Montgomery-Asberg Depression Rating Scale (MADRS) total score at week 8 (or last assessment if escitalopram, n=995; citalopram, n=1014). Escitalopram was significantly more effective than citalopram in overall treatment effect, with an estimated mean treatment difference of 1.7 points at week 8 (or last assessment if escitalopram. In this meta-analysis, the statistically significant superior efficacy of escitalopram compared to citalopram was shown to be clinically relevant.

  1. Utilization of 3-Month Yoga Program for Adults at High Risk for Type 2 Diabetes: A Pilot Study

    2011-01-01

    Full Text Available Various modes of physical activity, combined with dieting, have been widely recommended to prevent or delay type 2 diabetes. Among these, yoga holds promise for reducing risk factors for type 2 diabetes by promoting weight loss, improving glucose levels and reducing blood pressure and lipid levels. This pilot study aimed to assess the feasibility of implementing a 12-week yoga program among adults at high risk for type 2 diabetes. Twenty-three adults (19 Whites and 4 non-Whites were randomly assigned to the yoga intervention group or the educational group. The yoga group participated in a 3-month yoga intervention with sessions twice per week and the educational group received general health educational materials every 2 weeks. All participants completed questionnaires and had blood tests at baseline and at the end of 3 months. Effect sizes were reported to summarize the efficacy of the intervention. All participants assigned to the yoga intervention completed the yoga program without complication and expressed high satisfaction with the program (99.2%. Their yoga session attendance ranged from 58.3 to 100%. Compared with the education group, the yoga group experienced improvements in weight, blood pressure, insulin, triglycerides and exercise self-efficacy indicated by small to large effect sizes. This preliminary study indicates that a yoga program would be a possible risk reduction option for adults at high risk for type 2 diabetes. In addition, yoga holds promise as an approach to reducing cardiometabolic risk factors and increasing exercise self-efficacy for this group.

    OBJECTIVE Prospective longitudinal outcomes registries are at the center of evidence-driven health care reform. Obtaining real-world outcomes data at 12 months can be costly and challenging. In the present study, the authors analyzed whether 3-month outcome measurements sufficiently represent 12-month outcomes for patients with degenerative lumbar disease undergoing surgery. METHODS Data from 3073 patients undergoing elective spine surgery for degenerative lumbar disease were entered into a prospective multicenter registry (N(2)QOD). Baseline, 3-month, and 12-month follow-up Oswestry Disability Index (ODI) scores were recorded. The absolute differences between actual 12- and 3-month ODI scores was evaluated. Additionally, the authors analyzed the absolute difference between actual 12-month ODI scores and a model-predicted 12-month ODI score (the model used patients' baseline characteristics and actual 3-month scores). The minimal clinically important difference (MCID) for ODI of 12.8 points and the substantial clinical benefit (SCB) for ODI of 18.8 points were used based on the previously published values. The concordance rate of achieving MCID and SCB for ODI at 3-and 12-months was computed. RESULTS The 3-month ODI scores differed from 12-month scores by an absolute difference of 11.9 ± 10.8, and predictive modeling estimations of 12-month ODI scores differed from actual 12-month scores by a mean (± SD) of 10.7 ± 9.0 points (p = 0.001). Sixty-four percent of patients (n = 1982) achieved an MCID for ODI at 3 months in comparison with 67% of patients (n = 2088) by 12 months; 51% (n = 1731) and 61% (n = 1860) of patients achieved SCB for ODI at 3 months and 12 months, respectively. Almost 20% of patients had ODI scores that varied at least 20 points (the point span of an ODI functional category) between actual 3- and 12-month values. In the aggregate analysis of achieving MCID, 77% of patients were concordant and 23% were discordant in achieving or not achieving

  4. The BREASTrial Stage II: ADM Breast Reconstruction Outcomes from Definitive Reconstruction to 3 Months Postoperative

    Mendenhall, Shaun D.; Anderson, Layla A.; Ying, Jian; Boucher, Kenneth M.; Neumayer, Leigh A.

    2017-01-01

    Background: The Breast Reconstruction Evaluation of Acellular Dermal Matrix as a Sling Trial is a prospective randomized trial comparing outcomes of tissue expander breast reconstruction using either AlloDerm or DermaMatrix. The trial was divided into 3 outcome stages; this study reports stage II outcomes, which are those from the time of definitive reconstruction to 3 months postoperative. Methods: A randomized trial was conducted to compare complication rates between AlloDerm and DermaMatrix groups. The impact of matrix type, age, obesity, radiation therapy, chemotherapy, and reconstruction type on complications was analyzed with regression models. Results: Of the 128 patients (199 breasts) who were randomly assigned into the trial, 111 patients (173 breasts) were available for analysis in stage II. There was no difference in overall rates of complications (15.4% vs 18.3%, P = 0.8) or implant loss (2.2% vs 3.7%, P = 0.5) between the AlloDerm and DermaMatrix groups, respectively. Obesity was the only significant predictor of complications on regression analysis (odds ratio, 4.31, P = 0.007). Matrix type, age, radiation therapy, chemotherapy, or reconstruction type had no impact on the incidence/severity of complications. Conclusions: Acellular dermal matrix (ADM) will likely continue to have a role in breast reconstructive surgery; however, caution should be taken when using ADM because of relatively high complication rates, especially in obese patients. The particular ADM product should be selected based on individual surgeon preference, experience, and success rates. These data and forthcoming long-term outcomes from the Breast Reconstruction Evaluation of Acellular Dermal Matrix as a Sling Trial will enable surgeons to carefully weigh the risks and benefits of ADM use in breast reconstruction.

    Full Text Available An important mechanism for learning speech sounds in the first year of life is ‘distributional learning’, i.e., learning by simply listening to the frequency distributions of the speech sounds in the environment. In the lab, fast distributional learning has been reported for infants in the second half of the first year; the present study examined whether it can also be demonstrated at a much younger age, long before the onset of language-specific speech perception (which roughly emerges between 6 and 12 months. To investigate this, Dutch infants aged 2 to 3 months were presented with either a unimodal or a bimodal vowel distribution based on the English /æ/~/ε/ contrast, for only twelve minutes. Subsequently, mismatch responses (MMRs were measured in an oddball paradigm, where one half of the infants in each group heard a representative [æ] as the standard and a representative [ε] as the deviant, and the other half heard the same reversed. The results (from the combined MMRs during wakefulness and active sleep disclosed a larger MMR, implying better discrimination of [æ] and [ε], for bimodally than unimodally trained infants, thus extending an effect of distributional training found in previous behavioral research to a much younger age when speech perception is still universal rather than language-specific, and to a new method (ERP. Moreover, the analysis revealed a robust interaction between the distribution (unimodal vs. bimodal and the identity of the standard stimulus ([æ] vs. [ε], which provides evidence for an interplay between a perceptual asymmetry and distributional learning. The outcomes show that distributional learning can affect vowel perception already in the first months of life.

    2015-06-01

    Full Text Available OBJECTIVE: to test a theoretical model based on the Parent-Based Expansion of the Theory of Planned Behavior examining relation between selected parental, teenager and cultural variables and Latino teenagers' intentions to engage in sexual behavior.METHOD: a cross-sectional correlational design based on a secondary data analysis of 130 Latino parent and teenager dyads.RESULTS: regression and path analysis procedures were used to test seven hypotheses and the results demonstrated partial support for the model. Parent familism and knowledge about sex were significantly associated with parents' attitudes toward sexual communication with their teenagers. Parent Latino acculturation was negatively associated with parents' self-efficacy toward sexual communication with their teenagers and positevely associated with parents' subjective norms toward sexual communication with their teenagers. Teenager knowledge about sex was significantly associated with higher levels of teenagers' attitudes and subjective norms about sexual communication with parents. Only the predictor of teenagers' attitudes toward having sex in the next 3 months was significantly associated with teenagers' intentions to have sex in the next 3 months.CONCLUSION: the results of this study provide important information to guide future research that can inform development of interventions to prevent risky teenager sexual behavior among Latinos.

Best corrected visual acuity (BCVA, refraction, and steep keratometry were analyzed 3 months and 1 year after surgery. All patients self-administered the National Eye Institute Refractive Error Quality of life instrument at 2 time points: after having worn best correction for at least 30 days since evaluation (mean 4 months after surgery and 1 year after surgery. To analyze if the use of the appropriate correction at 1 year follow up had any impact on visual acuity and V-QoL, patients were divided into 2 groups: group A (appropriate correction and B (not appropriate correction.Results: After 1 year, QoL changes related to scales ‘clarity of vision’, ‘near vision’, and ‘far vision’. Keratometric values, sphere, and spherical equivalent did not differ significantly between 3 months and 1 year postoperative. Cylinder increase was statistically but not clinically significant. Binocular BCVA did not change 1 year after surgery in group A and showed a clinically significant impairment in group B. A year after surgery, 18 patients did not use correction suggested by a physician 3 months after surgery. QoL was not statistically different 1 year after surgery between group A and group B.Conclusion: Our findings show that the way keratoconic patients see is difficult to analyze using only quantitative and 1-visit metrics. They highlight the importance of patients’ self perception and performing longitudinal analysis to consider neural compensation to optical changes from surgery.Keywords: keratoconus, cornea

    2009-11-01

    The efficacy of eye movement desensitization and reprocessing (EMDR) in children with post-traumatic stress symptoms was meta-analytically examined from the perspective of incremental efficacy. Overall post-treatment effect size for EMDR was medium and significant (d=.56). Results indicate efficacy of EMDR when effect sizes are based on comparisons between the EMDR and the non-established trauma treatment or the no-treatment control groups, and the incremental efficacy when effect sizes are based on comparisons between the EMDR and the established (CBT) trauma treatment. The discussion focuses on the future replication of EMDR findings and further research on post-traumatic stress in children.

    Full Text Available Pregnancy increases the risk of being overweight at a later time period, particularly when there is excessive gestational weight gain. There remains a paucity of data into the effect of low glycaemic index (GI pregnancy interventions postpartum. Aim: To examine the impact of a low glycaemic index diet during pregnancy on maternal diet 3 months postpartum. Methodology: This analysis examined the diet, weight and lifestyle of 460 participants of the ROLO study 3 months postpartum. Questionnaires on weight, physical activity, breastfeeding, supplement use, food label reading and dietary habits were completed. Results: The intervention group had significantly greater weight loss from pre-pregnancy to 3 months postpartum than the control group (1.3 vs. 0.1 kg, p = 0.022. The intervention group reported greater numbers following a low glycaemic index diet (p < 0.001 and reading food labels (p = 0.032 and had a lower glycaemic load (GL (128 vs. 145, p = 0.014 but not GI (55 vs. 55, p = 0.809 than controls. Conclusions: Low GI dietary interventions in pregnancy result in improved health-behaviours and continued reported compliance at 3 months postpartum possibly through lower dietary GL as a result of portion control. Greater levels of weight loss from pre-pregnancy to 3 months postpartum in the intervention group may have important positive implications for overweight and obesity.

In this meta-analysis, we sought to study and compare the efficacy of most of these methods.Methods: Eligible studies were retrieved from PubMed and Embase for the following BLVR methods: one-way valves, sealants (BioLVR, LVR coils, airway bypass stents, and bronchial thermal vapor ablation. Primary study outcomes included the mean change post-intervention in the lung function tests, the 6-minute walk distance, and the St George's Respiratory Questionnaire. Secondary outcomes included treatment-related complications.Results: Except for the airway bypass stents, all other methods of BLVR showed efficacy in primary outcomes. However, in comparison, the BioLVR method showed the most significant findings and was the least associated with major treatment-related complications. For the BioLVR method, the mean change in forced expiratory volume (in first second was 0.18 L (95% confidence interval [CI]: 0.09 to 0.26; P<0.001; in 6-minute walk distance was 23.98 m (95% CI: 12.08 to 35.88; P<0.01; and in St George's Respiratory Questionnaire was −8.88 points (95% CI: −12.12 to −5.64; P<0.001.Conclusion: The preliminary findings of our meta-analysis signify the importance of most methods of BLVR. The magnitude of the effect on selected primary outcomes shows noninferiority, if not equivalence, when compared to what is known for surgical LVR.Keyword: emphysema, endobronchial valves, sealants, stents, coils

    Full Text Available Abstract Background Patients who self-poison have high repetition and high mortality rates. Therefore, appropriate follow-up is important. The aims of the present work were to study treatment received, satisfaction with health care services, and psychiatric symptoms after hospitalization for self-poisoning. Methods A cohort of patients who self-poisoned (n = 867 over a period of 1 year received a questionnaire 3 months after discharge. The Beck Depression Inventory (BDI, Beck Hopelessness Scale (BHS, and Generalized Self-Efficacy Scale (GSE were used. The participation rate was 28% (n = 242; mean age, 41 years; 66% females. Results Although only 14% of patients were registered without follow-up referrals at discharge, 41% reported no such measures. Overall, satisfaction with treatment was fairly good, although 29% of patients waited more than 3 weeks for their first appointment. A total of 22% reported repeated self-poisoning and 17% cutting. The mean BDI and BHS scores were 23.3 and 10.1, respectively (both moderate to severe. The GSE score was 25.2. BDI score was 25.6 among patients with suicide attempts, 24.9 for appeals, and 20.1 for substance-use-related poisonings. Conclusions Despite plans for follow-up, many patients reported that they did not receive any. The reported frequency of psychiatric symptoms and self-harm behavior indicate that a more active follow-up is needed.

    2015-07-01

    To our knowledge, no previous meta-analysis has attempted to compare the efficacy of pharmacological, psychological and combined treatments for the three main anxiety disorders (panic disorder, generalized anxiety disorder and social phobia). Pre-post and treated versus control effect sizes (ES) were calculated for all evaluable randomized-controlled studies (n = 234), involving 37,333 patients. Medications were associated with a significantly higher average pre-post ES [Cohen's d = 2.02 (1.90-2.15); 28,051 patients] than psychotherapies [1.22 (1.14-1.30); 6992 patients; P < 0.0001]. ES were 2.25 for serotonin-noradrenaline reuptake inhibitors (n = 23 study arms), 2.15 for benzodiazepines (n = 42), 2.09 for selective serotonin reuptake inhibitors (n = 62) and 1.83 for tricyclic antidepressants (n = 15). ES for psychotherapies were mindfulness therapies, 1.56 (n = 4); relaxation, 1.36 (n = 17); individual cognitive behavioural/exposure therapy (CBT), 1.30 (n = 93); group CBT, 1.22 (n = 18); psychodynamic therapy 1.17 (n = 5); therapies without face-to-face contact (e.g. Internet therapies), 1.11 (n = 34); eye movement desensitization reprocessing, 1.03 (n = 3); and interpersonal therapy 0.78 (n = 4). The ES was 2.12 (n = 16) for CBT/drug combinations. Exercise had an ES of 1.23 (n = 3). For control groups, ES were 1.29 for placebo pills (n = 111), 0.83 for psychological placebos (n = 16) and 0.20 for waitlists (n = 50). In direct comparisons with control groups, all investigated drugs, except for citalopram, opipramol and moclobemide, were significantly more effective than placebo. Individual CBT was more effective than waiting list, psychological placebo and pill placebo. When looking at the average pre-post ES, medications were more effective than psychotherapies. Pre-post ES for psychotherapies did not differ from pill placebos; this finding cannot be explained by heterogeneity, publication bias or allegiance effects. However, the decision on whether to choose

  4. Implant stability and marginal bone level of microgrooved zirconia dental implants: A 3-month experimental study on dogs

    Delgado-Ruíz Rafael Arcesio

    2014-01-01

    Full Text Available Background/Aim. The modification of implant surfaces could affect mechanical implant stability as well as dynamics and quality of peri-implant bone healing. The aim of this 3-month experimental study in dogs was to investigate implant stability, marginal bone levels and bone tissue response to zirconia dental implants with two laser-micro-grooved intraosseous surfaces in comparison with nongrooved sandblasted zirconia and sandblasted, high-temperature etched titanium implants. Methods. Implant surface characterization was performed using optical interferometric profilometry and energy dispersive X-ray spectroscopy. A total of 96 implants (4 mm in diameter and 10 mm in length were inserted randomly in both sides of the lower jaw of 12 Fox Hound dogs divided into groups of 24 each: the control (titanium, the group A (sandblasted zirconia, the group B (sandblasted zirconia plus microgrooved neck and the group C (sandblasted zirconia plus all microgrooved. All the implants were immediately loaded. Insertion torque, periotest values, radiographic crestal bone level and removal torque were recorded during the 3-month follow-up. Qualitative scanning electon micro-scope (SEM analysis of the bone-implant interfaces of each group was performed. Results. Insertion torque values were higher in the group C and control implants (p the control > the group B > the group A (p the control > the group B > the group A (p < 0.05. SEM showed that implant surfaces of the groups B and C had an extra bone growth inside the microgrooves that corresponded to the shape and direction of the microgrooves. Conclusion. The addition of micro-grooves to the entire intraosseous surface of zirconia dental implants enhances primary and secondary implant stability, promotes bone tissue ingrowth and preserves crestal bone levels.

  6. Action experience alters 3-month-old infants’ perception of others’ actions

    Sommerville, Jessica A.; Woodward, Amanda L.; Needham, Amy

    2014-01-01

    An intervention facilitated 3-month-old infants’ apprehension of objects either prior to (reach first), or after (watch first) viewing another person grasp similar objects in a visual habituation procedure. Action experience facilitated action perception: reach-first infants focused on the relation between the actor and her goal, but watch-first infants did not. Infants’ sensitivity to the actor’s goal was correlated with their engagement in object-directed contact with the toys. These findings indicate that infants can rapidly form goal-based action representations and suggest a developmental link between infants’ goal directed actions and their ability to detect goals in the actions of others.

    2015-07-01

    Full Text Available We present a 14-year-old boy with a grade III splenic injury due to a bicycle accident, who was treated conservatively. The boy’s medical history included splenomegaly due to thalassemia. The splenic lesion was initially investigated with computed tomography (CT and then, was followed by ultrasonography for 3 months. CT revealed a large intraparenchymal hematoma which appeared hyperechoic on ultrasonography. During follow-up, the hematoma developed a more complex echogenicity and became gradually hypoechoic. The hematoma increased in size during the first week but then, started decreasing until it eventually resolved completely. The patient had an uneventful full recovery. In this report, we discuss the ultrasonographic changes of the hematoma throughout the healing process.

  8. A 3-month age difference profoundly alters the primary rat stromal vascular fraction phenotype

    Quaade, Marlene Louise; Jensen, Charlotte Harken; Andersen, Ditte Caroline;

    2016-01-01

    The stromal vascular fraction (SVF) is a heterogeneous population obtained from collagenase digestion of adipose tissue. When cultured the population becomes more homogeneous and the cells are then termed adipose stromal/stem cells (ASCs). Both the freshly isolated primary SVF population...... and the cultured ASC population possess regenerative abilities suggested to be mediated by paracrine mechanisms mainly. The use of ASCs and SVF cells, both in animal studies and human clinical studies, has dramatically increased during recent years. However, more knowledge regarding optimal donor characteristics...... such as age is demanded. Here we report that even a short age difference has an impact on the phenotype of primary SVF cells. We observed that a 3-month difference in relatively young adult rats affects the expression pattern of several mesenchymal stem cell markers in their primary SVF. The younger animals...

  9. Subclavian Artery Pseudoaneurysm Formation 3 Months after a Game of Rugby Union

    T. Evans

    2015-01-01

    Full Text Available Pseudoaneurysms of the subclavian artery remain a rare complication after fracture of the clavicle. We report a case of delayed diagnosis of a subclavian artery pseudoaneurysm after a closed fracture of the clavicle in a 15-year-old patient, 3 months after the original injury while playing rugby union. Despite several attendances to the Emergency Department with vague symptoms, the final diagnosis was confirmed by duplex ultrasound and Computed Tomography of the thorax. Surgical repair was indicated due to acute limb ischaemia from distal embolisation from a large pseudoaneurysm, with the patient making a full recovery. This case highlights the need for clinical vigilance when assessing patients, particularly on repeated occasions when their recovery appears to be impaired. A thorough history and clinical examination can raise suspicion of even rare occurrences and aid prompt management.

  10. SSL Pricing and Efficacy Trend Analysis for Utility Program Planning

    Tuenge, Jason R.

    2013-10-01

    An LED lamp or luminaire can generally be found that matches or exceeds the efficacy of benchmark technologies in a given product category, and LED products continue to expand into ever-higher lumen output niches. However, the price premium for LED continues to pose a barrier to adoption in many applications, in spite of expected savings from reduced energy use and maintenance. Other factors—such as dimmability and quality of light—can also present challenges. The appropriate type, timing, and magnitude of energy efficiency activities will vary from organization to organization based on local variables and the method of evaluation. A number of factors merit consideration when prioritizing activities for development. Category-specific projections for pricing and efficacy are provided herein to assist in efficiency program planning efforts.

  14. A meta-analysis of probiotic efficacy for gastrointestinal diseases.

    Marina L Ritchie

    Full Text Available BACKGROUND: Meta-analyses on the effects of probiotics on specific gastrointestinal diseases have generally shown positive effects on disease prevention and treatment; however, the relative efficacy of probiotic use for treatment and prevention across different gastrointestinal diseases, with differing etiology and mechanisms of action, has not been addressed. METHODS/PRINCIPAL FINDINGS: We included randomized controlled trials in humans that used a specified probiotic in the treatment or prevention of Pouchitis, Infectious diarrhea, Irritable Bowel Syndrome, Helicobacter pylori, Clostridium difficile Disease, Antibiotic Associated Diarrhea, Traveler's Diarrhea, or Necrotizing Enterocolitis. Random effects models were used to evaluate efficacy as pooled relative risks across the eight diseases as well as across probiotic species, single vs. multiple species, patient ages, dosages, and length of treatment. Probiotics had a positive significant effect across all eight gastrointestinal diseases with a relative risk of 0.58 (95% (CI 0.51-0.65. Six of the eight diseases: Pouchitis, Infectious diarrhea, Irritable Bowel Syndrome, Helicobacter pylori, Clostridium difficile Disease, and Antibiotic Associated Diarrhea, showed positive significant effects. Traveler's Diarrhea and Necrotizing Enterocolitis did not show significant effects of probiotcs. Of the 11 species and species mixtures, all showed positive significant effects except for Lactobacillus acidophilus, Lactobacillus plantarum, and Bifidobacterium infantis. Across all diseases and probiotic species, positive significant effects of probiotics were observed for all age groups, single vs. multiple species, and treatment lengths. CONCLUSIONS/SIGNIFICANCE: Probiotics are generally beneficial in treatment and prevention of gastrointestinal diseases. Efficacy was not observed for Traveler's Diarrhea or Necrotizing Enterocolitis or for the probiotic species L. acidophilus, L. plantarum, and B

    Braboszcz, Claire; Cahn, B Rael; Balakrishnan, Bhavani; Maturi, Raj K; Grandchamp, Romain; Delorme, Arnaud

    2013-01-01

    Meditation has lately received considerable interest from cognitive neuroscience. Studies suggest that daily meditation leads to long lasting attentional and neuronal plasticity. We present changes related to the attentional systems before and after a 3 month intensive meditation retreat. We used three behavioral psychophysical tests - a Stroop task, an attentional blink task, and a global-local letter task-to assess the effect of Isha yoga meditation on attentional resource allocation. 82 Isha yoga practitioners were tested at the beginning and at the end of the retreat. Our results showed an increase in correct responses specific to incongruent stimuli in the Stroop task. Congruently, a positive correlation between previous meditation experience and accuracy to incongruent Stroop stimuli was also observed at baseline. We also observed a reduction of the attentional blink. Unexpectedly, a negative correlation between previous meditation experience and attentional blink performance at baseline was observed. Regarding spatial attention orientation as assessed using the global-local letter task, participants showed a bias toward local processing. Only slight differences in performance were found pre- vs. post- meditation retreat. Biasing toward the local stimuli in the global-local task and negative correlation of previous meditation experience with attentional blink performance is consistent with Isha practices being focused-attention practices. Given the relatively small effect sizes and the absence of a control group, our results do not allow clear support nor rejection of the hypothesis of meditation-driven neuronal plasticity in the attentional system for Isha yoga practice.

  16. Cortisol reactivity, maternal sensitivity, and learning in 3-month-old infants.

    Thompson, Laura A; Trevathan, Wenda R

    2008-01-01

    This study investigated the effects of adrenocortical functioning on infant learning during an emotionally challenging event (brief separation from mother). We also explored possible relationships between maternal sensitivity and both infant and maternal cortisol reactivity during the learning/maternal separation episode. Sixty-three 3-month-olds and their mothers were videotaped for a 10 min normal interaction period, and mother-infant behavioral synchrony was measured using Isabella and Belsky's [Isabella, R. A., & Belsky, J. (1991). Interactional synchrony and the origins of infant-mother attachment: A replication study. Child Development, 62, 373-384] coding scheme. The percentage of synchronous behaviors served as a measure of maternal sensitivity. Learning and short-term memory involved relating the infant's mother's voice with a moving colored block in a preferential looking paradigm. Infants whose cortisol increased during the session showed no learning or memory, infants whose cortisol declined appeared to learn and remember the association, while infants whose cortisol did not change evidenced learning, but not memory for the voice/object correspondence. Sensitivity and cortisol reactivity were correlated for mothers, but not for infants. Infant and maternal cortisol values for the first sampling period were highly correlated, but their cortisol reactivity values were uncorrelated, supporting the notion that infants and mothers have coordinated adrenocortical functioning systems when physically together, but become uncoordinated during a separation/learning event.

    2005-01-01

    Mycophenolate Mofetil MMF has been widely used in post-transplant immunosuppression. Its role is emerging in GN. MMF demonstrated promising results compared with cyclosphosphamide in stage IV lupus nephritis, in a recently published trial. It has been found to have a wide safety profile, with mostly gastroinetestinal side effects, which can be avoided through titration. Its action is through inhibition of the enzyme IMDPH (ionosine monophosphate dehydrogenase), leading to purine antagonism and inhibition of lymphocytes. We were aiming to demonstrate the efficacy of MMF in our GN population. In this study, we reviewed 17 patients who received MMF (dose - 1 gm po bid) for the past year. They were only included if it was given for the management of resistant primary glomerulonephritis. Complete remission has been defined as proteinuria of less than 0.5 g/day and partial remission as a reduction of proteinuria 50% of starting MMF therapy; all 17 MMF therapy patients uniformly achieved good BP ((29%) achieved complete remission and this group consisted of 1 membranous GN, 2 lupus GN (type IV and membranous), one FSGS and one with MPGN. Four of 17 (23%) were non-responders to therapy. This group articles.aspx? id=41 to side effects. We conclude that the MMF appears to be an effective alternate treatment modality in resistant membranous GN, lupus nephritis (type IV and V) and possibly MPGN, and to a lesser extent in resistant FSGS. Further prospective data may demonstrate the efficacy of MMF in GN.

    2011-12-01

    Full Text Available Abstract Background There is growing evidence of the effectiveness of Cognitive Behavioural Therapy (CBT for a wide range of psychological disorders. There is a continued controversy about whether challenging maladaptive thoughts rather than use of behavioural interventions alone is associated with the greatest efficacy. However little is known about the relative efficacy of various components of CBT. This review aims to compare the relative efficacy of Cognitive Therapy (CT versus Exposure (E for a range of anxiety disorders using the most clinically relevant outcome measures and estimating the summary relative efficacy by combining the studies in a meta-analysis. Methods Psych INFO, MEDLINE and EMBASE were searched from the first available year to May 2010. All randomised controlled studies comparing the efficacy of exposure with cognitive therapy were included. Odds ratios (OR or standardised means' differences (Hedges' g for the most clinically relevant primary outcomes were calculated. Outcomes of the studies were grouped according to specific disorders and were combined in meta-analyses exploring short-term and long-term outcomes. Results 20 Randomised Controlled Trials with (n = 1,308 directly comparing the efficacy of CT and E in anxiety disorders were included in the meta-analysis. No statistically significant difference in the relative efficacy of CT and E was revealed in Post Traumatic Stress Disorder (PTSD, in Obsessive Compulsive Disorder (OCD and in Panic Disorder (PD. There was a statistically significant difference favouring CT versus E in Social Phobia both in the short-term (Z = 3.72, p = 0.0002 and the long-term (Z = 3.28, p = 0.001 outcomes. Conclusions On the basis of extant literature, there appears to be no evidence of differential efficacy between cognitive therapy and exposure in PD, PTSD and OCD and strong evidence of superior efficacy of cognitive therapy in social phobia

  3. Plasticity of visual attention in Isha yoga meditation practitioners before and after a 3-month retreat

    2013-12-01

    Full Text Available Meditation has lately received considerable interest from cognitive neuroscience. Studies suggest that daily meditation leads to long lasting attentional and neuronal plasticity. We present changes related to the attentional systems before and after a 3 month intensive meditation retreat. We used 3 behavioral psychophysical tests - a Stroop task, an attentional blink task, and a global-local letter task - to assess the effect of Isha yoga meditation on attentional resource allocation. 82 Isha yoga practitioners were tested at the beginning and at the end of the retreat. Our results showed an increase in correct responses specific to incongruent stimuli in the Stroop task. Congruently, a positive correlation between previous meditation experience and accuracy to incongruent Stroop stimuli was also observed at baseline. We also observed a reduction of the attentional blink. Unexpectedly, a negative correlation between previous meditation experience and attentional blink performance at baseline was observed. Regarding spatial attention orientation as assessed using the global-local letter task, participants showed a bias toward local processing. Only slight differences in performance were found pre- vs. post- meditation retreat. Previous meditation experience influenced the Stroop and attentional blink tasks in opposite directions – for the Stroop task congruent with the improvements seen after the retreat whereas for the attentional blink previous experience correlated negatively with performance. Biasing towards the local stimuli in the global-local task and negative correlation of previous meditation experience with attentional blink performance is consistent with Isha practices being more focused-attention practices. Given the relatively small effect sizes and the absence of a control group, our results do not allow clear support nor rejection of the hypothesis of meditation-driven neuronal plasticity in the attentional system for Isha yoga

    Full Text Available Introduction. Laparoscopic Sleeve Gastrectomy (SG is considered as successful if the percentage of Excess Body Mass Index Loss (% EBMIL remains constant over 50% with long-term follow-up. The aim of this study was to evaluate whether early % EBMIL was predictive of success after SG. Methods. This retrospective study included patients who had SG with two years of follow-up. Patients had follow-up appointments at 3 (M3, 6, 12, and 24 months (M24. Data as weight and Body Mass Index (BMI were collected systematically. We estimated the % EBMIL necessary to establish a correlation between M3 and M24 compared to % EBMIL speeds and calculated a limit value of % EBMIL predictive of success. Results. Data at operative time, M3, and M24 were available for 128 patients. Pearson test showed a correlation between % EBMIL at M3 and that at M24 (r=0.74;  p<0.0001. % EBMIL speed between surgery and M3 (p=0.0011 was significant but not between M3 and M24. A linear regression analysis proved that % EBMIL over 20.1% at M3 (p<0.0001 predicted a final % EBMIL over 50%. Conclusions. % EBMIL at M3 after SG is correlated with % EBMIL in the long term. % EBMIL speed was significant in the first 3 months. % EBMIL over 20.1% at M3 leads to the success of SG.

    2014-01-01

    Targeting individuals' beliefs that they are able to eat healthily can improve dietary-related behaviours. However, the most effective behaviour change techniques (BCTs) to promote dietary self-efficacy have not been systematically reviewed. This research addressed this gap. Studies testing the effect of interventions on healthy eating and underlying dietary-related self-efficacy, within randomised controlled trials, were systematically reviewed in MEDLINE, EMBASE and PSYCINFO. Two reviewers independently coded intervention content in both intervention and comparison groups. Data pertaining to study quality were also extracted. Random effects meta-analysis was used to calculate an overall effect size on dietary self-efficacy for each study. The associations between 26 BCTs and self-efficacy effects were calculated using meta-regression. In some of the analyses, interventions that incorporated self-monitoring (tracking one's own food-related behaviour), provided feedback on performance, prompted review of behavioural goals, provided contingent rewards (rewarding diet success), or planned for social support/social change increased dietary self-efficacy significantly more than interventions that did not. Stress management was consistently associated with self-efficacy effects across all analyses. There was strong evidence for stress management and weaker evidence for a number of other BCTs. The findings can be used to develop more effective, theory- and evidence-based behavioural interventions.

    2017-01-01

    Background The efficacy of two artificial tears, carboxymethylcellulose (CMC) and hyaluronate (HA), was compared in the treatment of patients with dry eye disease. Methods We conducted a systematic review and meta-analysis on randomized controlled trials in the PubMed, Embase, Cochrane Library, and ClinicalTrials.gov databases. The efficacy was compared in terms of the mean change from baseline in tear break-up time. The meta-analysis was conducted using both random and fixed effect models. The quality of the selected studies was assessed for risk of bias. Results Five studies were included involving 251 participants. Random effect model meta-analysis showed no significant difference between CMC and HA in treating dry eye disease (pooled standardized mean difference [SMD]=-0.452; 95% confidence interval [CI], -0.911 to 0.007; P=0.053). In contrast, fixed effect model meta-analysis revealed significant improvements in the CMC group when compared to the HA group (pooled SMD=-0.334; 95% CI, -0.588 to -0.081; P=0.010). Conclusion The efficacy of CMC appeared to be better than that of HA in treating dry eye disease, although meta-analysis results were not statistically significant. Further research is needed to better elucidate the difference in efficacy between CMC and HA in treating dry eye disease. PMID:28197326

  8. Development and application of a method for analysis of lufenuron in wheat flour by gas chromatography-mass spectrometry and confirmation of bio-efficacy against Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae).

    Ahire, Kedar C; Arora, Manjit S; Mukherjee, Samindra N

    2008-01-01

    A new analytical method using gas chromatography with mass spectrometry (GC-MS) for the quantitative determination of lufenuron, a benzoylphenylurea (BPU) class of insecticide, from wheat flour has been developed and applied for time-dependent residue monitoring in treated wheat flour. The analyte was extracted from wheat flour by a single step solid-liquid extraction by using ethyl acetate and subsequently cleaned up using the Primary Secondary Amine as a sorbent prior to GC-MS analysis. The present method provides sufficient sensitivity as reflected by the values of limit of detection (LOD) and limit of quantification (LOQ), 5 ng/mL (S/N approximately 3) and 50 ng/mL (the lowest validation point on the calibration curve), respectively. The calibration curve showed an excellent linearity in the concentration range of 50-1000 ng/mL (r2=0.998). The average recovery for spiked samples at three concentrations (150, 300, and 450 ng/g) was 98.23+/-2.52% R.S.D. The method was applied for the determination of lufenuron residues in treated wheat flour samples. Simultaneous determination of bio-efficacy of lufenuron residues was also carried out against the red flour beetle, Tribolium castaneum to correlate the actual residual effect of lufenuron as detected by the analytical method, over a period of 3 months. The findings revealed that the residual concentration of lufenuron were neither uniform nor in descending order over a period of 3 months in wheat flour, possibly because of an uneven dispersal in the treated wheat which was subsequently milled into flour, as confirmed by GC-MS analysis. However, the residues of lufenuron were sufficient to produce 100% mortality of T. castaneum larvae up to 3 months. The results have been discussed in view of the potential of lufenuron as a candidate molecule for the control of stored product pests.

    2012-01-01

    Full Text Available This subgroup analysis assessed the efficacy of duloxetine in patients with chronic low back pain (CLBP who did or did not use concomitant nonsteroidal anti-inflammatory drugs (NSAIDs or acetaminophen (APAP. Data were pooled from two 13-week randomized trials in patients with CLBP who were stratified according to NSAID/APAP use at baseline: duloxetine NSAID/APAP user (=137, placebo NSAID/APAP user (=82, duloxetine NSAID/APAP nonuser (=206, and placebo NSAID/APAP nonuser (=156. NSAID/APAP users were those patients who took NSAID/APAP for at least 14 days per month during 3 months prior to study entry. An analysis of covariance model that included therapy, study, baseline NSAID/APAP use (yes/no, and therapy-by-NSAID/APAP subgroup interaction was used to assess the efficacy. The treatment-by-NSAID/APAP use interaction was not statistically significant (=0.31 suggesting no substantial evidence of differential efficacy for duloxetine over placebo on pain reduction or improvement in physical function between concomitant NSAID/APAP users and non-users.

    2009-07-30

    Despite decades of investigation in countries on three continents, an efficacious vaccine against Leishmania infections has not been developed. Although some indication of protection was observed in some of the controlled trials conducted with "first-generation" whole, inactivated Leishmania parasite vaccines, convincing evidence of protection was lacking. After reviewing all previously published or unpublished randomized, controlled field efficacy clinical trials of prophylactic candidate vaccines, a meta-analysis of qualified trials was conducted to evaluate whether there was some evidence of protection revealed by considering the results of all trials together. The findings indicate that the whole-parasite vaccine candidates tested do not confer significant protection against human leishmaniasis.

  1. Efficacy-mediated effects of spirituality and physical activity on quality of life: A path analysis

    Konopack James F

    2012-05-01

    Full Text Available Abstract Background Physical activity has been established as an important determinant of quality of life, particularly among older adults. Previous research has suggested that physical activity’s influence on quality of life perceptions is mediated by changes in self-efficacy and health status. In the same vein, spirituality may be a salient quality of life determinant for many individuals. Methods In the current study, we used path analysis to test a model in which physical activity, spirituality, and social support were hypothesized to influence global quality of life in paths mediated by self-efficacy and health status. Cross-sectional data were collected from a sample of 215 adults (male, n = 51; female, n = 164 over the age of 50 (M age = 66.55 years. Results The analysis resulted in a model that provided acceptable fit to the data (χ2 = 33.10, df = 16, p  Conclusions These results support previous findings of an efficacy-mediated relationship between physical activity and quality of life, with the exception that self-efficacy in the current study was moderately associated with physical health status (.38 but not mental health status. Our results further suggest that spirituality may influence health and well-being via a similar, efficacy-mediated path, with strongest effects on mental health status. These results suggest that those who are more spiritual and physically active report greater quality of life, and the effects of these factors on quality of life may be partially mediated by perceptions of self-efficacy.

The reproducibility and completeness were guaranteed in the information search and extraction. Heterogeneity, sensitivity and publication bias were assessed by graphical methods (Galbraith, L'Abblé, funnel plot, Egger plot, and influence plot and analytical methods (DerSimonian-Laird, Begg and Egger. Random-effects forest plots were constructed, and a cumulative meta-analysis was performed.Eight studies were included with 622 patients who underwent thermotherapy, with an efficacy of 73.2% (95% confidence interval (CI = 69.6-76.7%, and with 667 patients who underwent systemic treatment, with an efficacy of 70.6% (95% CI=67.1-74.1%. Heterogeneity between studies, good sensitivity for the combined measure, and no publication bias were observed. The relative risk for comparison of the efficacy of treatment was 1.02 (95%CI=0.91, 1.15, showing that the effectiveness of thermotherapy is equal to that of pentavalent antimonial drugs.Due to its efficacy, greater safety and lower cost, thermotherapy should be the first treatment option for cutaneous leishmaniasis in areas where the prevalence of the mucocutaneous form is low and in patients with contraindications to systemic treatment, such as kidney, liver and heart diseases, as well as in pregnant women, infants, and patients with human immunodeficiency virus infection/acquired immune deficiency syndrome.

  3. The Leadership Efficacy of Graduates of North Carolina School of Science and Mathematics: A Mixed-Methods Analysis

    Mason, Letita Renee

    This study examines the leadership efficacy amongst graduates of NCSSM from the classes of 2000--07 as the unit of analysis. How do NCSSM graduates' perceptions of their leadership efficacy align with research on non-cognitive variables as indicators of academic performance using the unit of analysis as a performance outcome? This study is based on the theoretical construct that non-cognitive psychological (also called motivational) factors are core components of leadership self-efficacy, indicative of NCSSM graduates (who had high academic performance and attained STEM degrees). It holds promise for increasing both student interest and diversity in the race to strengthen the STEM pipeline. In this study the Hannah and Avolio (2013) Mind Garden Leadership Efficacy Questionnaire (LEQ) is used. The LEQ is a battery of three instruments designed to assess individual perceptions of personal leadership efficacy across three constructs, via one survey tool. In this mixed-methods analysis, a quantitative phase was conducted to collect the data captured by the Mind Garden Leadership Efficacy Questionnaire. A Post Hoc qualitative analysis was conducted in the second phase of the data analysis, using the Trichotomous-Square Test methodology (with an associated qualitative researcher-designed Inventive Investigative Instrument). The results from the study validated the alternative hypothesis [H1], which proposed that there no are significant differences in the perception of the Leadership Efficacy by the North Carolina School of Science and Mathematics Alumni from the classes of 2000-07 in terms of their overall "Leadership Efficacy" in regards to: Execution or "Leadership Action Efficacy"; Capacity or "Leader Means Efficacy"; and Environment or "Leader Self-Regulation Efficacy" was accepted. The results also led to the development of a new assessment tool called the Mason Leadership Efficacy Model.

    An in vitro antimicrobial activity and phytochemical analysis of various extracts of Indigofera trita L. viz. petroleum ether, chloroform, acetone, ethanol and aqueous extracts were carried out. A total of 21 microorganisms (19 bacteria and 2 fungal strains) were used for antimicrobial activity by disc diffusion method and a standard procedure was used to identify the phytochemical constituents. Petroleum ether extract showed moderate inhibitory activity against Staphylococcus aureus (14.40 mm), S. epidermidis (14.20 mm), Salmonella paratyphi A (12.80 mm), Streptococcus mutans (12.20 mm), Escherichia coli, Proteus vulgaris, S. typhi and Burkholderia cepacia (12.00 mm). The chloroform extract also showed antimicrobial activity against S. epidermidis (14.20 mm), S. typhimurium (12.60 mm), S. paratyphi A, S. brunei and Yersinia enterocolitica (12.00 mm). The acetone extract of I. trita showed considerable inhibitory activity against S. epidermidis (18.20 mm), S. typhimurium (14.60 mm), S. infantis (13.80 mm), S. aureus (13.40 mm), Y. enterocolitica (13.00 mm) and Enterobacter aerogenes (12.00 mm) were documented. Ethanol extract showed significant antimicrobial activity against S. epidermidis (18.60 mm), S. paratyphi A (14.60 mm), Y. enterocolitica (13.40 mm), S. typhi (12.40 mm), S. aureus, E. aerogenes, S. typhimurium and S. infantis (12.00 mm). Aqueous extract of I. trita considerably inhibited S. epidermidis (13.80 mm), S. paratyphi A and Y. enterocolitica (12.20 mm), E. aerogenes and Haemophilus parahaemolyticus (12.00 mm). All the five extracts showed a minimal antifungal activity when compared to antibacterial activity. The result revealed that the antimicrobial properties of I. trita might be associated with the presence of phenolic compounds, flavonoids, tannins, glycosides, saponins, phytosterols and alkaloids.

    Full Text Available Objective. The objective of this systematic review and meta-analysis was to assess the efficacy of auricular therapy by including a sham therapy control group. Methods. Relevant, randomized clinical trials (RCTs were identified by searching medical related databases from, depending on journal, 1900 (at the earliest to 1994 (at the latest through May 2013. The outcome measure was a pain intensity score. Results. Twenty-two RCTs were identified and 13 RCTs were included for meta-analysis. In these studies, auricular therapy provided significant pain relief when compared to a sham or control group. The overall standardized mean differences (SMD was 1.59 (95% CI [−2.36, −0.82] (13 trials, total subject numbers = 806, indicating that, on average, the mean decrease in pain score for auricular therapy group was 1.59 standard deviations greater than the mean decrease for the sham control. In terms of the efficacy of the different treatment methods, auricular acupressure boasts the largest strength of evidence for pain relief, followed by auricular acupuncture. Electroacupuncture stimulation did not show significant evidence for efficacy, which may be due to the small sample size (i.e., only 19 subjects were included. Conclusion. Further large-scale RCTs are needed to determine the efficacy of auricular therapy for pain.

    This randomized controlled trial was designed to evaluate the effectiveness of using crisis coping cards (n = 32) in the case management of suicide prevention compared with case management without the use of coping cards (n = 32) over a 3-month intervention period. The generalized estimating equation was used to examine the interaction effect between treatments and time on suicide risk, depression, anxiety, and hopelessness. Results indicated that subsequent suicidal behaviors, severity of suicide risk, depression, anxiety, and hopelessness were reduced more in the coping card intervention group compared to the case management only group. Moreover, for the survival curves of time to suicide reattempt, the coping card group showed a significantly longer time to reattempt than the case management only group at 2-month and 3-month intervention periods.

    Purpose The aim of this study was to evaluate the decrease of benign thyroid nodules after bipolar radiofrequency ablation (RFA) in a 3-month follow-up using a multiple overlapping shot technique ('MOST'). Methods A total of 18 patients with 20 symptomatic benign thyroid nodules (17 cold nodules, 3 hyperfunctioning nodules) were treated in one single session by bipolar RFA. Bipolar ablation was performed using MOST. The nodule volumes were measured prior to ablation and 3 months after the procedure using ultrasound. The population consisted of either solid (>80% solid tissue within the volume of interest), complex, or cystic nodules (thermoablative technique to treat benign thyroid nodules. Combined with the multiple overlapping shot technique it allows sufficient ablation.

    Full Text Available Abstract Background Inadequate management of postoperative pain is common, and postoperative pain is a risk factor for prolonged pain. In addition to medical and technical factors, psychological factors may also influence the experience of postoperative pain. Methods Pain was measured postoperatively at 24, 48, and 72 hr in hospital and after 3 months at home in 140 patients undergoing radical prostatectomy (RP. Patients answered questionnaires about anxiety and depression (HAD scale and health-related quality of life (SF-36 at baseline and 3 months after surgery. Results In the first 3 postoperative days, mild pain was reported by 45 patients (32%, moderate pain by 64 (45%, and severe pain by 31 (22% on one or more days. High postoperative pain scores were correlated with length of hospital stay and with high pain scores at home. Forty patients (29% reported moderate (n = 35 or severe (n = 5 pain after discharge from hospital. Patients who experienced anxiety and depression preoperatively had higher postoperative pain scores and remained anxious and depressed 3 months after surgery. The scores for the physical domains in the SF-36 were decreased, while the mental health scores were increased at 3 months. Anxiety and depression were negatively correlated with all domains of the SF-36. Conclusion There is a need for nurses to be aware of the psychological status of RP patients and its impact upon patients' experience of postoperative pain and recovery. The ability to identify patients with psychological distress and to target interventions is an important goal for future research.

  10. In the first 3 months after stroke is progressive resistance training safe and does it improve activity? A systematic review.

    Salter, Karen; Musovic, Amie; F Taylor, Nicholas

    2016-10-01

    BACKGROUND Progressive resistance training (PRT) can improve strength and function in people with chronic stroke, but less is known about whether this intervention is safe and beneficial during the first 3 months following stroke. OBJECTIVE To systematically review the evidence about the safety and effectiveness of PRT to improve activity in people within the first 3 months after stroke. METHODS After database searching and selection of studies a risk of bias assessment was conducted. Data for the primary outcome of safety was synthesised descriptively and meta-analyses for other outcomes were conducted using a random effects model. RESULTS The quality of the 5 included studies ranged from good to excellent (mean 24.2, range 20-28). For the trials investigating adverse events, none reported any significant increase in events after PRT. There was high level evidence that PRT had little or no effect on strength (SMD (standardized mean difference) 0.17, 95% CI -0.16 to 0.50, I(2) = 0%). There were no significant benefit for upper limb function (SMD 0.11, 95% CI -0.41 to 0.63, I(2) = 0%) and mobility (SMD 0.11, 95% CI -0.21 to 0.43, I(2) = 27%) after PRT compared with controls. CONCLUSIONS There was no evidence reported that PRT is unsafe in people within the first 3 months after stroke, although there was a lack of reporting about adverse events. The lack of demonstration of effect in improving muscle strength and activity suggests there is insufficient evidence to recommend the prescription of PRT for people within the first 3 months after stroke.

    There are a few quantitative ultrasound (QUS) studies of bone status for Chinese children. To evaluate the clinical application and to investigate the bone status of neonates and young infants with QUS. An ultrasound bone sonometer was used to measure the bone speed of sound (SOS) of the tibia in 542 neonates within 3 months of birth. At birth, no significant difference of SOS was found between boys and girls, but there was a significant difference of SOS between premature infants and full-term infants. The SOS in neonates born during spring and summer was significantly lower than those born during autumn and winter. There were significant correlations between SOS and gestational age, and between bone SOS and birth weight in appropriate for gestational age (AGA) infants. Multiple regression analysis found that gestational age and infant birth season were two important factors influencing SOS. During the first 3 months, there was no significant difference in SOS between sexes. The SOS of infants showed an inverse correlation with postnatal age, and the decrease of bone SOS with age in premature infants was more marked than in full-term infants. QUS is suitable for evaluating bone status in infants with high precision. The study offers some basic data for neonates and young infants. (orig.)

    Peng, Song; Zhao, Min; Wan, Jing; Fang, Qi; Fang, Dong; Li, Kaiyong

    2014-12-20

    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.

    Semeniuk, Yulia Yuriyivna; Brown, Roger L; Riesch, Susan K

    2016-07-01

    We conducted a two-group longitudinal partially nested randomized controlled trial to examine whether young adolescent youth-parent dyads participating in Mission Possible: Parents and Kids Who Listen, in contrast to a comparison group, would demonstrate improved problem-solving skill. The intervention is based on the Circumplex Model and Social Problem-Solving Theory. The Circumplex Model posits that families who are balanced, that is characterized by high cohesion and flexibility and open communication, function best. Social Problem-Solving Theory informs the process and skills of problem solving. The Conditional Latent Growth Modeling analysis revealed no statistically significant differences in problem solving among the final sample of 127 dyads in the intervention and comparison groups. Analyses of effect sizes indicated large magnitude group effects for selected scales for youth and dyads portraying a potential for efficacy and identifying for whom the intervention may be efficacious if study limitations and lessons learned were addressed.

    To cite this article: Howarth P, Malling H-J, Molimard M, Devillier P. Analysis of allergen immunotherapy studies shows increased clinical efficacy in highly symptomatic patients. Allergy 2012; 67: 321-327. ABSTRACT: Background:  The assessment of allergen immunotherapy (AIT) efficacy...... in the treatment for seasonal allergic rhinoconjunctivitis (SAR) symptoms is challenging. Allergen immunotherapy differs from symptomatic therapy in that while symptomatic therapy treats patients after symptoms appear and aims to reduce symptoms, AIT is administered before symptoms are present and aims to prevent...... them. Thus, clinical studies of AIT can neither establish baseline symptom levels nor limit the enrolment of patients to those with the most severe symptoms. Allergen immunotherapy treatment effects are therefore diluted by patients with low symptoms for a particular pollen season. The objective...

    2011-05-01

    Rufinamide is a new orally active antiepileptic drug that has been found to be effective in the treatment of partial seizures and drop attacks associated with Lennox-Gastaut syndrome. We performed a quantitative analysis of the efficacy of this new antiepileptic drug from all double-blind, add-on, randomized, placebo-controlled clinical trials published to date. Data from 918 patients were studied. The number of patients per study varied from 25 to 262. Rufinamide was efficacious in doses up to 45 mg/kg daily when provided as adjunctive therapy in patients with Lennox-Gastaut syndrome and other drug-resistant epilepsies. Further studies are needed to confirm and expand these findings.

    2016-01-01

    Objective To systematically review and assess the efficacy, different treatment protocols (formulation, dosage, and duration), and safety of nystatin for treating oral candidiasis. Methods Four electronic databases were searched for trials published in English till July 1, 2015. Randomized controlled trials comparing nystatin with other antifungal therapies or a placebo were included. Clinical and/or mycological cure was the outcome evaluation. A meta-analysis or descriptive study on the efficacy, treatment protocols, and safety of nystatin was conducted. Results The meta-analysis showed that nystatin pastille was significantly superior to placebo in treating denture stomatitis. Nystatin suspension was not superior to fluconazole in treating oral candidiasis in infants, children, or HIV/AIDS patients. The descriptive investigations showed that administration of nystatin suspension and pastilles in combination for 2 weeks might achieve a higher clinical and mycological cure rate, and using the nystatin pastilles alone might have a higher mycological cure rate, when compared with using nystatin suspensions alone. Nystatin pastilles at a dose of 400,000 IU resulted in a significantly higher mycological cure rate than that administrated at a dose of 200,000 IU. Furthermore, treatment with nystatin pastilles for 4 weeks seemed to have better clinical efficacy than treatment for 2 weeks. Descriptive safety assessment showed that poor taste and gastrointestinal adverse reaction are the most common adverse effects of nystatin. Conclusion Nystatin pastille was significantly superior to placebo in treating denture stomatitis, while nystatin suspension was not superior to fluconazole in treating oral candidiasis in infants, children, or HIV/AIDS patients. Indirect evidence from a descriptive study demonstrated that administration of nystatin pastille alone or pastille and suspension in combination is more effective than that of suspension alone; prolonged treatment duration

    2016-10-01

    Full Text Available Background: Managemen of myofascial pain syndrome (MPS is a current research subject since there is a small number of randomized studies comparing different management techniques. Multiple studies attempted to assess various treatment options including trigger point dry needling and kinesiotaping. We compared the effects of trigger point dry needling and kinesiotaping in the management of myofascial pain syndome during a 3-month follow-up period. Methods: In this prospective randomized studyin MPS patients with upper trapezius muscle trigger points, the effects of dry needling (n=28 and kinesiotaping (n=27 was compared with regard to the visual analog scale (VAS, neck disability index (NDI, and Nottingham health profile (NHP scores measured at the weeks 0, 4, and 12. Results: Both dry needling and kinesiotaping comparably reduced VAS scores measured at the weeks 4 and 12 and their efficacies were more remarkable at the week 12 (p<0.05. These interventions significantly reduced the NDI and NHP score and their effects were also more remarkable at the week 12; however, dry needling was found more effective (p<0.05. Conclusion: Overall, in current clinical settings, during the management of MPS, pain can be reduced comparably by both dry needling and kinesiotaping; however, restriction in the range of motionin neck region and quality of life are more remarkably reduced by dry needling. Both dry needling and kinesiotaping can provide an increasing effectiveness up to 12 weeks.

  18. Longer Weekly Sleep Duration Predicts Greater 3-Month BMI Reduction among Obese Adolescents Attending a Clinical Multidisciplinary Weight Management Program

    Bethany J. Sallinen

    2013-05-01

    Full Text Available Aims: To determine whether baseline levels of self-reported sleep and sleep problems among obese adolescents referred to an outpatient multidisciplinary family-based weight management program predict reduction in BMI 3 months later. Methods: A retrospective medical chart review was conducted for 83 obese adolescents. The following baseline variables were extracted: self-reported sleep duration (weekdays and weekends, and presence of snoring, daytime fatigue, suspected sleep apnea, and physician-diagnosed sleep apnea. Anthropometric data at baseline and 3 months were also collected. Results: On average, adolescents reported significantly less sleeping on weeknights (7.7 ± 1.3 h compared to weekend nights (10.0 ± 1.8 h, t(82 = 10.5, p = 0.0001. Reduction in BMI after 3 months of treatment was predicted by more weekly sleep at baseline (R2 = 0.113, F(1, 80 = 10.2, p = 0.002. Adolescents who reduced their BMI by ≥1 kg/m2 reported greater weekly sleep at baseline compared to adolescents who experienced 2 reduction (60.7 ± 7.5 h vs. 56.4 ± 8.6 h; F(1, 80 = 5.7, p = 0.02. Conclusion: Findings from this study, though correlational, raise the possibility that increased duration of sleep may be associated with weight loss among obese adolescents enrolled in a weight management program. Evidence-based behavioral techniques to improve sleep hygiene and increase sleep duration should be explored in pediatric weight management settings.

    2014-09-15

    Magnetic resonance cholangiopancreatography (MRCP) could aid in the diagnosis of biliary atresia, a hepatic pathology with thin, irregular or interrupted biliary ducts. There is little published evidence of MRCP appearances in normal neonates and young infants. To assess the use of MR cholangiopancreatography in visualizing the biliary tree in neonates and infants younger than 3 months with no hepatobiliary disorder, and to assess this visibility in relationship to the child's age, weight, and sedation and fasting states. Between December 2008 and October 2010 our department performed MRI of the brain, orbits and face on 16 full-term neonates and infants. Each child was younger than 3 months (90 days) and without any hepatobiliary disorders. The children were scanned with a respiratory-gated 0.54 x 0.51 x 0.4-mm{sup 3} 3-D MRCP sequence. We used a reading grid to assess subjectively the visibility of the extrahepatic bile ducts along with extrahepatic bile duct confluence. The visibility of the extrahepatic bile duct confluence was assessed against age, weight, and sedation and fasting states. The extrahepatic bile duct confluence was seen in 10 children out of 16 (62.5%). In the neonate sub-group (corrected age younger than 30 days), the MRCP was technically workable and the extrahepatic bile duct confluence was seen in four cases out of eight (50%). This visualization was up to 75% in the subgroup older than 30 days. However, statistically there was no significant difference in visibility of the extrahepatic bile duct confluence in relationship to age, weight or MRCP performance conditions (feeding, fasting or sedation). The complete normal biliary system (extrahepatic bile duct confluence included) is not consistently visualized in infants younger than 3 months old on non-enhanced MRCP. Thus the use of MRCP to exclude a diagnosis of biliary atresia is compromised at optimal time of surgery. (orig.)

  20. Prenatal exposure to polychlorinated biphenyls and their hydroxylated metabolites is associated with neurological functioning in 3-month-old infants.

    2014-12-01

    Polychlorinated biphenyls (PCBs) are environmental chemicals which are potentially toxic to the developing brain. Their hydroxylated metabolites (OH-PCBs) are suggested to be even more toxic. Knowledge about the health effects of prenatal OH-PCB exposure is limited. We aimed to determine whether prenatal background exposure to PCBs and OH-PCBs is associated with neurological functioning in 3-month-old boys and girls. In a Dutch observational cohort study, we measured 10 PCBs and 6 OH-PCBs in maternal blood samples of 98 pregnant women. We assessed their infants neurologically with Touwen examination at 3 months and calculated an Optimality Score (OS, range 0-53, low-high optimality). We calculated correlation coefficients between compound levels and OS. Subsequently, we tested whether levels were associated with specific clusters and whether levels differed between infants with "normal" (dysfunction on ≤1 cluster) and "non-optimal" development (dysfunction on ≥2 clusters). The mean OS was 48 (range 44-52). Higher exposure to PCB-146 correlated significantly with higher OS (r = 0.209; p = 0.039). In boys, higher exposure to 4-OH-PCB-107 correlated with lower OS (r = -0.305; p = 0.030). Higher exposure to 9 PCBs and the sum of all PCBs was associated with better visuomotor and/or better sensorimotor function. Infants classified as "non-optimal" (n = 36) had significantly lower prenatal exposure to 6 PCBs and the sum of all PCBs (p < 0.05) compared with infants classified as "normal" (n = 62). In conclusion, higher prenatal exposure to Dutch background PCB levels is associated with better neurological functioning in 3-month-old infants. Prenatal exposure to 4-OH-PCB-107 is associated with less optimal neurological functioning in boys.

    2016-12-22

    Three-month long-acting paliperidone is a new, recently marketed, formulation of paliperidone, characterised by the longest available dosing interval among long-acting antipsychotics. The clinical profile of 3-month long-acting paliperidone was recently summarised by the European Medicines Agency (EMA) in a public assessment report, released in April 2016. In this commentary, the main strengths and limitations of the EMA assessment report were appraised and discussed, in order to highlight possible implications for clinical practice, future research and regulatory practices for drug approval.

  2. Traumatic dissecting aneurysm at the vertebrobasilar junction in a 3-month-old infant: evaluation and treatment strategies. Case report.

    Wang, Huan; Orbach, Darren B

    2008-05-01

    Intracranial aneurysms in young infants are extremely rare, with few published reports on the etiology, evaluation, treatment strategies, and follow-up of this condition in this population. The authors report the case of a traumatic dissecting aneurysm at the vertebrobasilar junction (VBJ) in a 3-month-old infant caused by nonaccidental trauma. Therapeutic occlusion of the VBJ was contemplated, but coil embolization of the main aneurysm sac proved feasible, and anticoagulation and antiplatelet agents were initiated. The patient made a full neurological recovery, and follow-up studies demonstrated stable aneurysm occlusion. Management and follow-up strategies for this challenging condition are discussed.

  3. The Efficacy of Acupuncture for the Treatment of Sciatica: A Systematic Review and Meta-Analysis

    2015-01-01

    Full Text Available Background. Sciatica is one of the most frequently reported complaints; it affects quality of life and reduces social and economic efficacy. Clinical studies on the efficacy of acupuncture therapy in sciatica are increasing, while systematic reviews assessing the efficacy of acupuncture therapy are still lacking. Objective. This study aims to assess the effectiveness of acupuncture therapy for sciatica. Methods. Comprehensive searches of 8 databases were conducted up until April 2015. Outcomes included effectiveness (proportion of patients who improved totally or partly in clinical symptoms, pain intensity, and pain threshold. Effect sizes were presented as risk ratio (RR and mean difference (MD. Pooled effect sizes were calculated by fixed effects or random effects model. Results. A total of 12 studies (involving 1842 participants were included. Results showed that acupuncture was more effective than conventional Western medicine (CWM in outcomes effectiveness (RR 1.21, 95% CI: 1.16–1.25, pain intensity (MD −1.25, 95% CI: −1.63 to −0.86, and pain threshold (MD: 1.08, 95% CI: 0.98–1.17. Subgroup and sensitivity analysis found that the results did not change in different treatment method and drug categories substantially. The reported adverse effects were acceptable. Conclusions. Acupuncture may be effective in treating the pain associated with sciatica.

  4. Predicting in vivo anti-hepatofibrotic drug efficacy based on in vitro high-content analysis.

    Baixue Zheng

    Full Text Available BACKGROUND/AIMS: Many anti-fibrotic drugs with high in vitro efficacies fail to produce significant effects in vivo. The aim of this work is to use a statistical approach to design a numerical predictor that correlates better with in vivo outcomes. METHODS: High-content analysis (HCA was performed with 49 drugs on hepatic stellate cells (HSCs LX-2 stained with 10 fibrotic markers. ~0.3 billion feature values from all cells in >150,000 images were quantified to reflect the drug effects. A systematic literature search on the in vivo effects of all 49 drugs on hepatofibrotic rats yields 28 papers with histological scores. The in vivo and in vitro datasets were used to compute a single efficacy predictor (E(predict. RESULTS: We used in vivo data from one context (CCl(4 rats with drug treatments to optimize the computation of E(predict. This optimized relationship was independently validated using in vivo data from two different contexts (treatment of DMN rats and prevention of CCl(4 induction. A linear in vitro-in vivo correlation was consistently observed in all the three contexts. We used E(predict values to cluster drugs according to efficacy; and found that high-efficacy drugs tended to target proliferation, apoptosis and contractility of HSCs. CONCLUSIONS: The E(predict statistic, based on a prioritized combination of in vitro features, provides a better correlation between in vitro and in vivo drug response than any of the traditional in vitro markers considered.

    2013-01-01

    We studied the effects of a high intensity and high frequency 3-month training program on muscle damage and neutrophil function in male judoists. The study included 15 male judoists who started intensive judo training program after a 6-month break. Creatine kinase (CK), neutrophil counts and reactive oxygen species (ROS) production capability as well as phagocytic activity (PA) of neutrophils were measured at 2 stages; entering university (pre-training) and after 3-month training (post-training). At both points, we investigated parameters three times: just before, immediately after and 24 h after a 2-h practice session. Practice-mediated change in CK was lower at post-training than at pre-training. Neutrophil count significantly increased after 2-h practice but recovered 24 h later whereas it showed no subsequent and further increased at 24 h post-practice. Although neutrophil ROS production capability and PA both decreased (breakdown) after practice session, ROS production capability increased and PA decreased (well-adapted) at the post-training. Long-term training strengthened muscular function and improved neutrophil reaction against practice-mediated stress.

  6. Predicting In Vivo Anti-Hepatofibrotic Drug Efficacy Based on In Vitro High-Content Analysis

    2011-01-01

    BACKGROUND/AIMS: Many anti-fibrotic drugs with high in vitro efficacies fail to produce significant effects in vivo. The aim of this work is to use a statistical approach to design a numerical predictor that correlates better with in vivo outcomes. METHODS: High-content analysis (HCA) was performed with 49 drugs on hepatic stellate cells (HSCs) LX-2 stained with 10 fibrotic markers. ~0.3 billion feature values from all cells in >150,000 images were quantified to reflect the drug effects.

    Purpose The purpose of this study was to apply Rasch analysis to examine the unidimensionality and reliability of the General Self-Efficacy Scale (GSE) in workers with traumatic limb injuries. Furthermore, if the items of the GSE fitted the Rasch model's assumptions, we transformed the raw sum ordinal scores of the GSE into Rasch interval scores. Methods A total of 1076 participants completed the GSE at 1 month post injury. Rasch analysis was used to examine the unidimensionality and person reliability of the GSE. The unidimensionality of the GSE was verified by determining whether the items fit the Rasch model's assumptions: (1) item fit indices: infit and outfit mean square (MNSQ) ranged from 0.6 to 1.4; and (2) the eigenvalue of the first factor extracted from principal component analysis (PCA) for residuals was Rasch scores. Conclusions The results indicated that the items of GSE are unidimensional and have acceptable person reliability in workers with traumatic limb injuries. Additionally, the raw sum scores of the GSE can be transformed into Rasch interval scores for prospective users to quantify workers' levels of self-efficacy and to conduct further statistical analyses.

    Zinc acexamate (ZAC) is a new drug for the treatment of peptic ulcer. The present study was performed in order to evaluate the clinical efficacy of ZAC in peptic ulcer, using a meta-analysis of all randomized clinical trials performed with this drug. Eighteen studies were reviewed, but only 13 were considered in the final analysis. The total number of patients was 757. Control groups included placebo or H2 receptor antagonist drugs. Healing rate, assessed by endoscopy, was selected as the criterion for evaluating drug efficacy. The meta-analysis was performed using a modified version of the Mantel-Haenszel method. ZAC proved to be better than placebo in the treatment of peptic ulcer (pooled odds ratio: POR = 5.55; 95% confidence interval: 95% CI = 2.20-14.04) and not different from H2 receptor antagonist drugs when compared in patients with gastric (POR = 1.14; 95% CI = 0.47-2.72), duodenal (POR = 0.97; 95% CI = 0.13-7.33) or both ulcer types (POR = 1.10; 95% CI = 0.74-1.64). The present results show that ZAC is an effective drug for the treatment of peptic ulcer.

  9. Escitalopram versus paroxetine for social anxiety disorder: an analysis of efficacy for different symptom dimensions

    Stein, Dan J; Andersen, Elisabeth Anne Wreford; Lader, Malcolm

    2006-01-01

    BACKGROUND: A previous factor analysis of pooled data demonstrated that the Liebowitz Social Anxiety Scale (LSAS) can be divided into six subscales. This paper examines data from a fixed-dose trial of escitalopram versus paroxetine, in order to determine the differential effects of these agents...... on symptom dimensions in social anxiety disorder (SAD). METHODS: Data from a 24-week randomised, placebo-controlled, comparative study of fixed doses of escitalopram (5 mg, 10 mg, 20 mg) versus paroxetine (20 mg) in SAD were examined. The six factors identified in a previous factor analysis of baseline data...... from escitalopram studies on the primary efficacy scale, the LSAS, were used to compute subscale scores. These were analysed using analysis of covariance (ANCOVA), and standardised effect sizes were calculated. RESULTS: The combined escitalopram data and the paroxetine data both demonstrated...

    Full Text Available Xin Lyu, Chen Zhao, Zhi-min Yan, Hong HuaDepartment of Oral Medicine, Peking University School and Hospital of Stomatology, Beijing, People’s Republic of ChinaObjective: To systematically review and assess the efficacy, different treatment protocols (formulation, dosage, and duration, and safety of nystatin for treating oral candidiasis.Methods: Four electronic databases were searched for trials published in English till July 1, 2015. Randomized controlled trials comparing nystatin with other antifungal therapies or a placebo were included. Clinical and/or mycological cure was the outcome evaluation. A meta-analysis or descriptive study on the efficacy, treatment protocols, and safety of nystatin was conducted.Results: The meta-analysis showed that nystatin pastille was significantly superior to placebo in treating denture stomatitis. Nystatin suspension was not superior to fluconazole in treating oral candidiasis in infants, children, or HIV/AIDS patients. The descriptive investigations showed that administration of nystatin suspension and pastilles in combination for 2 weeks might achieve a higher clinical and mycological cure rate, and using the nystatin pastilles alone might have a higher mycological cure rate, when compared with using nystatin suspensions alone. Nystatin pastilles at a dose of 400,000 IU resulted in a significantly higher mycological cure rate than that administrated at a dose of 200,000 IU. Furthermore, treatment with nystatin pastilles for 4 weeks seemed to have better clinical efficacy than treatment for 2 weeks. Descriptive safety assessment showed that poor taste and gastrointestinal adverse reaction are the most common adverse effects of nystatin.Conclusion: Nystatin pastille was significantly superior to placebo in treating denture stomatitis, while nystatin suspension was not superior to fluconazole in treating oral candidiasis in infants, children, or HIV/AIDS patients.

    2006-01-01

    In the field of consumer-used cosmetics for hair removal and hair growth reduction, there is a need for improved quantitative methods to enable the evaluation of efficacy and claim support. Optimized study designs and investigated endpoints are lacking to compare the efficacy of standard methods, like shaving or plucking, with new methods and products, such as depilating instruments or hair-growth-reducing cosmetics. Non-invasive image analysis, using a high-performance microscope combined with an optimized image analysis tool, was investigated to assess hair growth. In one step, high-resolution macrophotographs of the legs of female volunteers after shaving and plucking with cold wax were compared to observe short-term hair regrowth. In a second step, images obtained after plucking with cold wax were taken over a long-term period to assess the time, after which depilated hairs reappeared on the skin surface. Using image analysis, parameters like hair length, hair width, and hair projection area were investigated. The projection area was found to be the parameter most independent of possible image artifacts such as irregularities in skin or low contrast due to hair color. Therefore, the hair projection area was the most appropriate parameter to determine the time of hair regrowth. This point of time is suitable to assess the efficacy of different hair removal methods or hair growth reduction treatments by comparing the endpoint after use of the hair removal method to be investigated to the endpoint after simple shaving. The closeness of hair removal and visible signs of skin irritation can be assessed as additional quantitative parameters from the same images. Discomfort and pain rating by the volunteers complete the set of parameters, which are required to benchmark a new hair removal method or hair-growth-reduction treatment. Image analysis combined with high-resolution imaging techniques is a powerful tool to objectively assess parameters like hair length, hair

Improvement in functional status score was significantly more in steroid group ( P =0.03. Conclusion : There was significant improvement in both groups, clinically as well as electrophysiologically, at 3 months. On comparing the efficacy of the two treatment methods, except for the functional status score, there was no significant difference between the two groups.

  13. Association of renal biomarkers with 3-month and 1-year outcomes among critically ill acute stroke patients.

    Ying-Chih Huang

    Full Text Available BACKGROUND: The comparative relationships of widely recognized biomarkers of renal injury with short-term and long-term outcomes among critically ill acute stroke patients are unknown. We evaluated the impact of baseline albuminuria [urine albumin-creatinine ratio (UACR ≥ 30 mg/g] or low estimated glomerular filtration rate (eGFR<60 ml/min per 1.73 m(2 on stroke patients admitted to the intensive care unit (ICU. METHODS: We reviewed data on consecutive stroke patients admitted to a hospital ICU in Taiwan from September 2007 to August 2010 and followed-up for 1 year. Baseline UACR was categorized into <30 mg/g (normal, 30-299 mg/g (microalbuminuria, and ≥ 300 mg/g (macroalbuminuria, while eGFR was divided into ≥ 60, 45-59, and <45 ml/min per 1.73 m(2. The outcome measure was death or disability at 3-month and 1-year after stroke onset, assessed by dichotomizing the modified Rankin Scale at 3-6 versus 0-2. RESULTS: Of 184 consecutive patients, 153 (83% met study entry criteria. Mean age was 67.9 years and median admission NIHSS score was 16. Among the renal biomarkers, only macroalbuminuria was associated with poorer 3-month outcome (OR 8.44, 95% CI 1.38 to 51.74, P = 0.021 and 1-year outcome (OR 18.06, 95% CI 2.59 to 125.94, P = 0.003 after adjustment of relevant covariates. When ischemic and hemorrhagic stroke were analyzed separately, macroalbuminuria was associated with poorer 1-year outcome among ischemic (OR 17.10, 95% CI 1.04 to 280.07, P = 0.047 and hemorrhagic stroke patients (OR 1951.57, 95% CI 1.07 to 3561662.85, P = 0.048, respectively, after adjustment of relevant covariates and hematoma volume. CONCLUSIONS: Presence of macroalbuminuria indicates poor 3-month and 1-year outcomes among critically ill acute stroke patients.

    2011-01-01

    Event-related potential studies of cognitive function in addiction behaviors have focused on the P300 event-related potential component. The current study investigated the association between P300 component and Internet addiction disorder. We found that individuals with Internet addiction disorder exhibited significantly longer P300 latencies than controls (N2: P = 0.035; P3a: P = 0.031; P3b: P = 0.043) and similar P300 amplitudes compared to control participants. After 3 months of cognitive behavioral therapy, P300 latencies decreased significantly in the P3a and P3b (P3a: P = 0.045; P3b: P = 0.062). These results suggest that deficits in cognitive function may be involved in Internet addiction disorder, and that clinical psychological treatment may be effective.

    Objectives Medical comorbidities affect outcome in elderly patients with hip fracture. This study was designed to preliminarily evaluate the usefulness of a hip-fracture unit led by an internal medicine specialist. Methods In-hospital and 3-month outcomes in patients with hip fracture were prospectively evaluated in 121 consecutive patients assessed before and followed after surgery by a multidisciplinary team led by internal medicine specialist; 337 consecutive patients were recalled from ICD-9 discharge records and considered for comparison regarding in-hospital mortality. Results In the intervention period, patients treated within 48 hours were 54% vs. 26% in the historical cohort (P<0.0001). In-hospital mortality remained stable at about 2.3 per 1000 person-days. At 3 months, 10.3% of discharged patients had died, though less than 8% of patients developed postoperative complications (mainly pneumonia and respiratory failure). The presence of more than 2 major comorbidities and the loss of 3 or more BADL were independent predictors of death. 50/105 patients recovered previous functional capacity, but no independent predictor of functional recovery could be identified. Mean length of hospital stay significantly decreased in comparison to the historical cohort (13.6± 4.7 vs 17 ± 5 days, p = 0.0001). Combined end-point of mortality and length of hospitalization < 12 days was significantly lower in study period (27 vs 34%, p <0.0132). Conclusions Identification and stabilization of concomitant clinical problems by internal medicine specialists may safely decrease time to surgery in frail subjects with hip fracture. Moreover, integrated perioperative clinical management may shorten hospital stay with no apparent increase in in-hospital mortality and ultimately improve the outcome. These results are to be confirmed by a larger study presently ongoing at our institution. PMID:27389193

    Objective Dipeptidyl peptidase-4 (DPP-4) inhibitors are the most frequently prescribed oral hypoglycemic agents in Japan. Although a relationship between the efficacy of DPP-4 inhibitors and the body mass index (BMI) has been reported, this relationship is controversial. We investigated whether the BMI value affects the glucose-lowering efficacy of sitagliptin in obese Japanese patients with type 2 diabetes. Methods One hundred sixty-two outpatients with inadequate glycemic control were divided into four groups based on their baseline BMI values. They were then treated with sitagliptin (a DPP-4 inhibitor) for 3 months and followed-up for 12 months. Results Sitagliptin significantly reduced the hemoglobin A1c level (HbA1c: -0.71±0.55%) after 3 months, and continued to reduce the HbA1c level until 12 months. There was no significant difference in the efficacy of sitagliptin among the four BMI groups. A multiple linear regression analysis indicated that the factors contributing to the change in the HbA1c level were the baseline level of HbA1c and the homeostasis model assessment of β-cell function (HOMA-β). In terms of the relationship between the baseline BMI value and the efficacy of sitagliptin treatment, the number of patients who responded to sitagliptin treatment after 3 months was lowest in the group of patients with the highest BMI values. A multiple logistic regression analysis revealed that the baseline HOMA-β function and HbA1c level and a baseline BMI value of ≥30 kg/m(2) significantly contributed to the response to sitagliptin treatment. Conclusion The results indicated that sitagliptin treatment was effective in controlling glucose metabolism disorder in obese Japanese patients with type 2 diabetes. However, the efficacy of sitagliptin treatment might be attenuated in severely obese patients, such as those with a BMI value of ≥30 kg/m(2).

    Thirty percent of all military personnel smoke cigarettes. Because of the negative health consequences and their impact on physical fitness, overall health, and military readiness, the Department of Defense has identified the reduction of tobacco use as a priority of US military forces. This study aims to evaluate the one-year efficacy of a proactive versus reactive smoking quit line in the US military with adjunctive nicotine replacement therapy (NRT) in both groups. This paper reports on the baseline variables of the first 1000 participants randomized, the design, and proposed analysis of the randomized two-arm clinical trial "Efficacy of a Tobacco Quit Line in the Military". Participants are adult smokers who are Armed Forces Active Duty personnel, retirees, Reservist, National Guard and family member healthcare beneficiaries. All participants are randomized to either the Counselor Initiated (proactive) group, receiving 6 counseling sessions in addition to an 8-week supply of NRT, or the Self-Paced (reactive) group, in which they may call the quit line themselves to receive the same counseling sessions, in addition to a 2-week supply of NRT. The primary outcome measure of the study is self-reported smoking abstinence at 1-year follow-up. Results from this study will be the first to provide evidence for the efficacy of an intensive Counselor Initiated quit line with provided NRT in military personnel and could lead to dissemination throughout the US Air Force, the armed forces population as a whole and ultimately to civilian personnel that do not have ready access to preventive health services.

  19. Comprehensive sieve analysis of breakthrough HIV-1 sequences in the RV144 vaccine efficacy trial.

    2015-02-01

    Full Text Available The RV144 clinical trial showed the partial efficacy of a vaccine regimen with an estimated vaccine efficacy (VE of 31% for protecting low-risk Thai volunteers against acquisition of HIV-1. The impact of vaccine-induced immune responses can be investigated through sieve analysis of HIV-1 breakthrough infections (infected vaccine and placebo recipients. A V1/V2-targeted comparison of the genomes of HIV-1 breakthrough viruses identified two V2 amino acid sites that differed between the vaccine and placebo groups. Here we extended the V1/V2 analysis to the entire HIV-1 genome using an array of methods based on individual sites, k-mers and genes/proteins. We identified 56 amino acid sites or "signatures" and 119 k-mers that differed between the vaccine and placebo groups. Of those, 19 sites and 38 k-mers were located in the regions comprising the RV144 vaccine (Env-gp120, Gag, and Pro. The nine signature sites in Env-gp120 were significantly enriched for known antibody-associated sites (p = 0.0021. In particular, site 317 in the third variable loop (V3 overlapped with a hotspot of antibody recognition, and sites 369 and 424 were linked to CD4 binding site neutralization. The identified signature sites significantly covaried with other sites across the genome (mean = 32.1 more than did non-signature sites (mean = 0.9 (p < 0.0001, suggesting functional and/or structural relevance of the signature sites. Since signature sites were not preferentially restricted to the vaccine immunogens and because most of the associations were insignificant following correction for multiple testing, we predict that few of the genetic differences are strongly linked to the RV144 vaccine-induced immune pressure. In addition to presenting results of the first complete-genome analysis of the breakthrough infections in the RV144 trial, this work describes a set of statistical methods and tools applicable to analysis of breakthrough infection genomes in general vaccine

    Zhang, L-W; Fu, J-Y; Hua, H; Yan, Z-M

    2016-04-01

    The objective of this study is to assess the efficacy and safety of miconazole for treating oral candidiasis. Twelve electronic databases were searched for randomized controlled trials evaluating treatments for oral candidiasis and complemented by hand searching. The clinical and mycological outcomes, as well as adverse effects, were set as the primary outcome criteria. Seventeen trials were included in this review. Most studies were considered to have a high or moderate level of bias. Miconazole was more effective than nystatin for thrush. For HIV-infected patients, there was no significant difference in the efficacy between miconazole and other antifungals. For denture wearers, microwave therapy was significantly better than miconazole. No significant difference was found in the safety evaluation between miconazole and other treatments. The relapse rate of miconazole oral gel may be lower than that of other formulations. This systematic review and meta-analysis indicated that miconazole may be an optional choice for thrush. Microwave therapy could be an effective adjunct treatment for denture stomatitis. Miconazole oral gel may be more effective than other formulations with regard to long-term results. However, future studies that are adequately powered, large-scale, and well-designed are needed to provide higher-quality evidence for the management of oral candidiasis.

    2009-01-01

    We aimed to evaluate the efficacy of tricyclic antidepressants (TCAs) as a therapeutic option for irritable bowel syndrome (IBS) through meta-analysis of randomized controlled trials. For the years 1966 until September 2008, PubMed, Scopus, Web of Science, and Cochrane Central Register of Controlled Trials were searched for double-blind, placebo-controlled trials investigating the efficacy of TCAs in the management of IBS. Seven randomized, placebo-controlled clinical trials met our criteria and were included in the metaanalysis. TCAs used in the treatment arm of these trials included amitriptyline, imipramine, desipramine, doxepin and trimipramine. The pooled relative risk for clinical improvement with TCA therapy was 1.93 (95% CI: 1.44 to 2.6, P<0.0001). Effect size of TCAs versus placebo for mean change in abdominal pain score among the two studies was -44.15 (95% CI: -53.27 to -35.04, P<0.0001). It is concluded that low dose TCAs exhibit clinically and statistically significant control of IBS symptoms.

  2. Can feedback analysis be used to uncover the physical origin of climate sensitivity and efficacy differences?

    Rieger, Vanessa S.; Dietmüller, Simone; Ponater, Michael

    2016-12-01

    Different strengths and types of radiative forcings cause variations in the climate sensitivities and efficacies. To relate these changes to their physical origin, this study tests whether a feedback analysis is a suitable approach. For this end, we apply the partial radiative perturbation method. Combining the forward and backward calculation turns out to be indispensable to ensure the additivity of feedbacks and to yield a closed forcing-feedback-balance at top of the atmosphere. For a set of CO2-forced simulations, the climate sensitivity changes with increasing forcing. The albedo, cloud and combined water vapour and lapse rate feedback are found to be responsible for the variations in the climate sensitivity. An O3-forced simulation (induced by enhanced NOx and CO surface emissions) causes a smaller efficacy than a CO2-forced simulation with a similar magnitude of forcing. We find that the Planck, albedo and most likely the cloud feedback are responsible for this effect. Reducing the radiative forcing impedes the statistical separability of feedbacks. We additionally discuss formal inconsistencies between the common ways of comparing climate sensitivities and feedbacks. Moreover, methodical recommendations for future work are given.

  3. Efficacy of Exercise Interventions in Patients with Acute Leukemia: A Meta-Analysis.

    Yuan Zhou

    Full Text Available Decreased physical performance and impaired physiological and psychological fitness have been reported in patients with acute leukemia (AL. We performed a meta-analysis to assess the efficacy of exercise in patients with AL.In this meta-analysis, the electronic databases MEDLINE, Embase, Cochrane, Web of Science, SPORTDiscus, CINAHL and PEDro were searched through November 2015. Three authors participated in the study selection, data extraction and quality assessment. The instrument used for quality assessment was derived from the Cochrane Handbook for Systematic Reviews of Interventions. Analyses were performed according to the recommendations of The Cochrane Collaboration using Review Manager 5.3.Nine trials (8 randomized controlled trials and 1 quasi-experimental design trial with 314 AL participants were included in this meta-analysis. The pooled standardized mean differences between the exercise and control groups were 0.45 (95% confidence interval (CI: 0.09 to 0.80, P value = 0.01, P for heterogeneity = 0.23, I2 = 28% for cardiorespiratory fitness and 0.67 (95% CI: 0.28 to 1.06, P value = 0.0007, P for heterogeneity = 0.14, I2 = 43% for muscle strength. Based on the data for fatigue, anxiety, and depression, there were no significant differences in these parameters between the exercise and control groups.Exercise has beneficial effects on cardiorespiratory fitness, muscle strength and functional mobility; however, no significant improvements in fatigue, anxiety, depression or quality of life were observed. Further large-scale randomized trials are needed to assess the safety, feasibility and efficacy of exercise programs for AL patients.

    2010-12-01

    Full Text Available Abstract Background With the relatively high rate of injuries to the lower extremity due to jump-landing movement patterns and the accompanied high costs, there is need for determining potential preventive programs. A program on the intervention of jump-landing technique is possibly an important preventative measure since it appeared to reduce the incidence of lower extremity injuries. In real life situations, amateur sports lack the infrastructure and funds to have a sports physician or therapist permanently supervising such a program. Therefore the current prevention program is designed so that it could be implemented by coaches alone. Objective The objective of this randomized controlled trial is to evaluate the effect of a coach supervised intervention program targeting jump-landing technique on the incidence of lower extremity injuries. Methods Of the 110 Flemish teams of the elite division, 24 teams are included and equally randomized to two study groups. An equal selection of female and male teams with allocation to intervention and control group is obtained. The program is a modification of other prevention programs previously proven to be effective. All exercises in the current program are adjusted so that a more progressive development in the exercise is presented. Both the control and intervention group continue with their normal training routine, while the intervention group carries out the program on jump-landing technique. The full intervention program has a duration of three months and is performed 2 times a week during warm-up (5-10 min. Injuries are registered during the entire season. Discussion The results of this study can give valuable information on the effect of a coach supervised intervention program on jump-landing technique and injury occurrence. Results will become available in 2011. Trial registration Trial registration number: NTR2560

    2010-01-01

    Monepantel is the first compound from the amino-acetonitrile derivative class of anthelmintics to be developed for the control of gastrointestinal nematodes of sheep. An analysis of pooled data from a series of controlled studies is reported providing a single point of efficacy (+/- 95% confidence interval) for each gastrointestinal nematode tested at the fourth larval and/or adult stages. For most nematode species, the pooled efficacy was greater than 99%, and for the remaining few species, efficacy was greater than 90%. These data are well supported by field studies conducted across five countries, where the pooled efficacy (on the basis of fecal worm egg count reduction) was in most cases, greater than 99% (depending on the calculation used). Monepantel is highly effective when administered to sheep at 2.5 mg/kg, and its introduction as a new anthelmintic for sheep is timely, given the problems with anthelmintic resistance that the world's sheep farmers are now experiencing.

    Full Text Available Objectives. The meta-analysis aims to investigate the efficacy of ectoine nasal spray and eye drops in the treatment of allergic rhinitis and rhinoconjunctivitis symptoms. Design and Methods. This meta-analysis is based on yet unpublished data of four studies. Both nasal and eye symptoms were documented in patient diary cards. All scales were transformed into a 4-point scale: 0 = no, 1 = mild, 2 = moderate, and 3 = severe symptoms. Each symptom was analysed individually in a meta-analysis of the area under the curve values as well as in a meta-analysis of pre- and posttreatment comparison. Results. After seven days of treatment with ectoine nasal spray both nasal and ocular symptoms decreased significantly. A strong reduction of symptom severity was shown for the parameters rhinorrhoea (31.76% reduction and nasal obstruction (29.94% reduction. Furthermore, the meta-analyses of individual symptoms to investigate the strength of effect after seven days of medication intake showed significant improvement for nasal obstruction, rhinorrhoea, nasal itching, sneezing, itching of eyes, and redness of eyes. The improvement of the symptom nasal obstruction was associated with a strong effect 0.53 (±0.26. Conclusions. The ectoine nasal spray and eye drops seem to be equally effective as guideline-recommended medication in the treatment of rhinoconjunctivitis symptoms.

    Full Text Available Cephalometric norms of McNamara analysis have been studied in various populations due to their optimal efficiency. Dolphin cephalometric software greatly enhances the conduction of this analysis for orthodontic measurements. However, Dolphin is very expensive and cannot be afforded by many clinicians in developing countries. A suitable alternative software program in Farsi/English will greatly help Farsi speaking clinicians. The present study aimed to develop an affordable Iranian cephalometric analysis software program and compare it with Dolphin, the standard software available on the market for cephalometric analysis.In this diagnostic, descriptive study, 150 lateral cephalograms of normal occlusion individuals were selected in Mashhad and Qazvin, two major cities of Iran mainly populated with Fars ethnicity, the main Iranian ethnic group. After tracing the cephalograms, the McNamara analysis standards were measured both with Dolphin and the new software. The cephalometric software was designed using Microsoft Visual C++ program in Windows XP. Measurements made with the new software were compared with those of Dolphin software on both series of cephalograms. The validity and reliability were tested using intra-class correlation coefficient.Calculations showed a very high correlation between the results of the Iranian cephalometric analysis software and Dolphin. This confirms the validity and optimal efficacy of the newly designed software (ICC 0.570-1.0.According to our results, the newly designed software has acceptable validity and reliability and can be used for orthodontic diagnosis, treatment planning and assessment of treatment outcome.

Therefore, we reviewed the relevant studies and conducted a meta-analysis to assess the efficacy of ifosfamide-based chemotherapy in patients with osteosarcoma.Methods: A systematic literature search on PubMed, Embase, and Web of Science databases was performed. Eligible studies were clinical trials of patients with osteosarcoma who received ifosfamide-based chemotherapy. Hazard ratios (HRs were pooled to compare event-free survival (EFS and overall survival (OS. Risk ratios (RRs were pooled to compare good histologic response rates and adverse event incidence. Meta-analysis was performed using a fixed-effects model or a random-effects model according to heterogeneity.Results: A total of seven randomized controlled trials were included in this meta-analysis. Pooled results showed that ifosfamide-based chemotherapy significantly improved EFS (HR=0.72, 95% confidence interval [CI]: 0.63, 0.82; P=0.000 and OS (HR=0.83, 95% CI: 0.70, 0.99; P=0.034; furthermore, this form of chemotherapy increased good histologic response rate (RR=1.27, 95% CI: 1.10, 1.46; P=0.001. In addition, patients in the ifosfamide group exhibited a significantly higher incidence of fever (RR=2.23, 95% CI: 1.42, 3.50; P=0.000 and required more frequent platelet transfusion (RR=1.92, 95% CI: 1.23, 3.01; P=0.004.Conclusion: This meta-analysis confirmed that ifosfamide-based chemotherapy can significantly improve EFS and OS; this chemotherapy can also increase good histologic response rate in patients with osteosarcoma

  13. Heart rate variability in schizophrenic patients switched from typical antipsychotic agents to amisulpride and olanzapine. 3-month follow-up.

    2008-01-01

    Schizophrenia is a severe mental disorder that requires lifelong treatment, and therefore information on the cardiovascular safety and tolerance of antipsychotics is of significant clinical importance. Atypical antipsychotics have been used to treat schizophrenia patients since the 1990s, and more and more patients have been switched to these from typical antipsychotics; however, there is still no accessible evaluation tool for assessing cardiovascular safety. In this study, we used a computer-assisted 5-min measurement of resting heart rate variability (HRV) in schizophrenia patients who were switched to atypical antipsychotic agents (amisulpride and olanzapine) due to severe side effects (tardive dyskinesia). In 15 patients who switched to amisulpride and 18 to olanzapine, HRV was evaluated before the medication was switched, and patients were followed up every month for 3 months after the switch. Frequency-domain analyses of short-term and stationary respiratory rate (RR) intervals were performed to evaluate low-frequency power (LF; 0.04-0.15 Hz), high-frequency power (HF; 0.15-0.40 Hz), the ratio of LF to HF (LF/HF), and LF in normalized units (LF%). Our results showed significant increases in the mean, variance and HF of RR intervals in the amisulpride group, but not in the olanzapine group. These results indicate that amisulpride has a more vagotonic effect, suggesting greater cardiovascular safety as compared with olanzapine when subjects are switched from typical antipsychotic agents.

  14. Self-controlled learning benefits: exploring contributions of self-efficacy and intrinsic motivation via path analysis.

    Ste-Marie, Diane M; Carter, Michael J; Law, Barbi; Vertes, Kelly; Smith, Victoria

    2016-09-01

    Research has shown learning advantages for self-controlled practice contexts relative to yoked (i.e., experimenter-imposed) contexts; yet, explanations for this phenomenon remain relatively untested. We examined, via path analysis, whether self-efficacy and intrinsic motivation are important constructs for explaining self-controlled learning benefits. The path model was created using theory-based and empirically supported relationships to examine causal links between these psychological constructs and physical performance. We hypothesised that self-efficacy and intrinsic motivation would have greater predictive power for learning under self-controlled compared to yoked conditions. Participants learned double-mini trampoline progressions, and measures of physical performance, self-efficacy and intrinsic motivation were collected over two practice days and a delayed retention day. The self-controlled group (M = 2.04, SD = .98) completed significantly more skill progressions in retention than their yoked counterparts (M = 1.3, SD = .65). The path model displayed adequate fit, and similar significant path coefficients were found for both groups wherein each variable was predominantly predicted by its preceding time point (e.g., self-efficacy time 1 predicts self-efficacy time 2). Interestingly, the model was not moderated by group; thus, failing to support the hypothesis that self-efficacy and intrinsic motivation have greater predictive power for learning under self-controlled relative to yoked conditions.

Also it is intended to examine the association between them. The population of the study is 3.817 (1.822 female, 1955 male student teachers in Faculty of Education at İnönü University during the first semester of 2007-2008 academic year. The sample of the study comprises 411 students chosen using proportional stratified sampling technique. Participants were given “Teachers Belief Survey” and “Teachers’ Sense of Efficacy Scale”. The data obtained were analyzed using descriptive statistical techniques, t-test, ANOVA, Kruskal Wallis, LSD, Mann Whitney U and Pearson correlation. The analysis revealed that participants’ professional self-efficacy levels were moderately over average and they had both constructivist and traditional beliefs, the former being moderately more dominant. The comparisons between independent groups (gender, grade, and department gave some results partly consistent with the relevant literature. Also a positive correlation was found between constructivist teacher beliefs and self-efficacy beliefs about student engagement, and between traditional teacher beliefs and self-efficacy beliefs about class management, instruction, and overall self-efficacy.

    This study evaluated the influence of different enamel thicknesses and bleaching agents on treatment efficacy in-depth by spectrophotometry color analysis. Eighty bovine dental fragments were previously stained in black tea solution and randomly assigned into eight groups (n=10), 1.75mm dentin thickness and different enamel thicknesses as follows: 0.5mm, 1.0mm planned, 1.0mm unplanned (aprismatic enamel), and absence of enamel. The 10% carbamide peroxide (CP) and 35% hydrogen peroxide (HP) bleaching gels were applied on the enamel surface following the manufacturer's recommendations. Color of underlying dentin was evaluated at four times: after staining with tea (baseline) and after each one of the three weeks of bleaching treatment, by CIE L*a*b* system using reflectance spectrophotometer (CM 700d, Konica Minolta). The ΔE, ΔL, Δa, and Δb values were recorded and subjected to repeated measures ANOVA and Tukey’s test (α=0.05). The results showed an increase on lightness (L*), with decreased redness (a*) and yellowness (b*). At first and second week, bleaching with CP showed higher whitening effectiveness compared to bleaching with HP and the presence of aprismatic enamel significantly reduced ΔE for bleaching with CP. After three weeks of bleaching, few differences were observed between CP and HP groups, and outer enamel layer caused no influence on bleaching effectiveness. Overall, both at-home and in-office bleaching treatments were effective and the presence of aprismatic enamel did not interfere on the whitening efficacy. PMID:27708725

    2015-04-01

    The purpose of this paper was to discover the relationships among 22 relevant psychological features in semi-professional football players in order to study team's performance and collective efficacy via a Bayesian network (BN). The paper includes optimization of team's performance and collective efficacy using intercausal reasoning pattern which constitutes a very common pattern in human reasoning. The BN is used to make inferences regarding our problem, and therefore we obtain some conclusions; among them: maximizing the team's performance causes a decrease in collective efficacy and when team's performance achieves the minimum value it causes an increase in moderate/high values of collective efficacy. Similarly, we may reason optimizing team collective efficacy instead. It also allows us to determine the features that have the strongest influence on performance and which on collective efficacy. From the BN two different coaching styles were differentiated taking into account the local Markov property: training leadership and autocratic leadership.

  20. How a hat may affect 3-month-olds' recognition of a face: an eye-tracking study.

    Hermann Bulf

    Full Text Available Recent studies have shown that infants' face recognition rests on a robust face representation that is resilient to a variety of facial transformations such as rotations in depth, motion, occlusion or deprivation of inner/outer features. Here, we investigated whether 3-month-old infants' ability to represent the invariant aspects of a face is affected by the presence of an external add-on element, i.e. a hat. Using a visual habituation task, three experiments were carried out in which face recognition was investigated by manipulating the presence/absence of a hat during face encoding (i.e. habituation phase and face recognition (i.e. test phase. An eye-tracker system was used to record the time infants spent looking at face-relevant information compared to the hat. The results showed that infants' face recognition was not affected by the presence of the external element when the type of the hat did not vary between the habituation and test phases, and when both the novel and the familiar face wore the same hat during the test phase (Experiment 1. Infants' ability to recognize the invariant aspects of a face was preserved also when the hat was absent in the habituation phase and the same hat was shown only during the test phase (Experiment 2. Conversely, when the novel face identity competed with a novel hat, the hat triggered the infants' attention, interfering with the recognition process and preventing the infants' preference for the novel face during the test phase (Experiment 3. Findings from the current study shed light on how faces and objects are processed when they are simultaneously presented in the same visual scene, contributing to an understanding of how infants respond to the multiple and composite information available in their surrounding environment.

    Background Non-penetrating trabecular surgery is a new filtrating surgery without opening in ternal trabecular structures. This study was to estimate the overall efficacy of non-penetrating trabecular surgery for open angle glaucoma.Methods The published articles selected for this study were obtained by a computerised Medline and China Biological Medicine Disk search of the literature and a manual search of the bibliographies of relevant articles. Articles meeting the inclusion criteria were reviewed systematically, and the reported data were aggregated using the statistical techniques of meta-analysis.Results A total of 37 articles were included in the meta-analysis. The pooled complete success rates of non-penetrating trabecular surgery with different techniques were: deep sclerectomy single, 69.7% (95% CI: 58.5%-81.0%); deep sclerectomy with collagen implant, 59.4% (95% CI: 47.0%-71.8%); deep sclerectomy with reticulated hyaluronic acid implant, 71.1% (95% CI: 56.8%-85.3%); and viscocanalostomy, 72.0% (95% CI: 57.6%-86.4%). The overall weighted complete success rate of non-penetrating trabecular surgery was 67.8% (95% CI: 61.4%-74.3%).Conclusions Non-penetrating trabecular surgery is the best available therapy method for medically uncontrolled open angle glaucoma with a complete success rate of over 60%. But the different techniques cannot belie the complete success rate of non-penetrating trabecular surgery.

    2015-04-01

    Annona muricata is a naturally occurring edible plant with wide array of therapeutic potentials. In India, it has a long history of traditional use in treating various ailments. The present investigation was carried out to characterize the phytochemicals present in the methanolic and aqueous leaf extracts of A. muricata, followed by validation of its radical scavenging and DNA protection activities. The extracts were also analyzed for its total phenolic contents and subjected to HPLC analysis to determine its active metabolites. The radical scavenging activities were premeditated by various complementary assays (DRSA, FRAP and HRSA). Further, its DNA protection efficacy against H2O2 induced toxicity was evaluated using pBR322 plasmid DNA. The results revealed that the extracts were highly rich in various phytochemicals including luteolin, homoorientin, tangeretin, quercetin, daidzein, epicatechin gallate, emodin and coumaric acid. Both the extracts showed significant (p < 0.05) radical scavenging activities, while methanolic extract demonstrated improved protection against H2O2-induced DNA damage when compared to aqueous extract. A strong positive correlation was observed for the estimated total phenolic contents and radical scavenging potentials of the extracts. Further HPLC analysis of the phyto-constituents of the extracts provides a sound scientific basis for compound isolation.

    To determine the therapeutic effect of nootropic agent Cerebrolysin on patients with mild to moderate Alzheimer's disease (AD), we searched the Cochrane Library, Medline, PubMed, and Chinese Biomedical Literature Analysis and Retrieval System for Compact Disc (CBMDISC), and communicated with EBEWE Pharmaceutical Ltd, for randomized trials comparing Cerebrolysin with placebo in AD. Available data on clinical global impression, cognitive performance and activities of daily living were extracted from 6 randomized double-blind placebo-controlled clinical trials and combined with standard meta-analysis methods. An infusion with Cerebrolysin for 4 weeks (30 ml Cerebrolysin daily on five consecutive days of each week) led to a significant improvement of the clinical global impression. Compared with placebo, log(OR) was 1.1799, and 95% confident interval was 0.7463-1.6135 (P Cerebrolysin could significantly improve the clinical global impression in patients with mild to moderate AD. However, more convincing evidences are needed for the efficacy of Cerebrolysin on the cognitive performance and activities of daily living.

    While liposome-mediated delivery of cytotoxic chemotherapy has been shown to significantly enhance drug tolerability in patients as compared to the conventional formulation, the fundamental question remains whether they also improve anticancer efficacy. Thus, we performed a systematic literature search for randomized clinical trials directly comparing efficacy of liposomal cytotoxic chemotherapy versus their equivalent conventional formulation. The search yielded 14 clinical trials (8 anthracycline, 4 cisplatin, 1 paclitaxel, 1 irinotecan) that meet inclusion criteria, with a total of 2589 patients. We found that efficacy in patients was not different between liposomal and conventional chemotherapy as assessed by objective response (odds ratio 1.03; 95% confidence interval [CI] 0.82-1.30), overall survival (hazard ratio [HR] 1.05; 95% CI 0.95-1.17), and progression free survival rates (HR 1.01; 95% CI, 0.92-1.11). Subgroup analyses of only the anthracycline trials also did not show any efficacy advantage for the liposomal formulation. Since pegylated liposomal doxorubicin (PLD) was the most prevalent formulation in these clinical trials, we also performed a meta-analysis of 11 preclinical studies comparing efficacy of PLD and conventional doxorubicin in tumor-bearing mice. In contrast with clinical results, animal studies showed significantly increased survival in mice treated with PLD compared to conventional doxorubicin (HR 0.39; 95% CI 0.27-0.56). We discuss the possible reasons why the pharmacological advantages of carrier-mediated chemotherapy did not translate into enhanced clinical efficacy including the role of the enhanced permeability and retention (EPR) effect and the tumor microenvironment, the optimal dosing regimen for carrier-mediated agents, and the lack of standardization in the conduct and reporting of preclinical studies evaluating anticancer efficacy of these agents. Our study shows that the full clinical potential of carrier-mediated drugs

  11. Item-response-theory analysis of two scales for self-efficacy for exercise behavior in people with arthritis.

    Mielenz, Thelma J; Edwards, Michael C; Callahan, Leigh F

    2011-07-01

    Benefits of physical activity for those with arthritis are clear, yet physical activity is difficult to initiate and maintain. Self-efficacy is a key modifiable psychosocial determinant of physical activity. This study examined two scales for self-efficacy for exercise behavior (SEEB) to identify their strengths and weaknesses using item response theory (IRT) from community-based randomized controlled trials of physical activity programs in adults with arthritis. The 2 SEEB scales included the 9-item scale by Resnick developed with older adults and the 5-item scale by Marcus developed with employed adults. All IRT analyses were conducted using the graded-response model. IRT assumptions were assessed using both exploratory and confirmatory factor analysis. The IRT analyses indicated that these scales are precise and reliable measures for identifying people with arthritis and low SEEB. The Resnick SEEB scale is slightly more precise at lower levels of self-efficacy in older adults with arthritis.

    González-Silva Jara

    2016-12-01

    Full Text Available The main objective of this study was to analyse the variables that predicted setting efficacy in complex I (KI in volleyball, in formative categories and depending on gender. The study sample was comprised of 5842 game actions carried out by the 16 male category and the 18 female category teams that participated in the Under-16 Spanish Championship. The dependent variable was setting efficacy. The independent variables were grouped into: serve variables (a serve zone, the type of serve, striking technique, an in-game role of the server and serve direction, reception variables (a reception zone, a receiver player and reception efficacy and setting variables (a setter‘s position, a setting zone, the type of a set, setting technique, a set’s area and tempo of a set. Multinomial logistic regression showed that the best predictive variables of setting efficacy, both in female and male categories, were reception efficacy, setting technique and tempo of a set. In the male category, the jump serve was the greatest predictor of setting efficacy, while in the female category, it was the set’s area. Therefore, in the male category, it was not only the preceding action that affected setting efficacy, but also the serve. On the contrary, in the female category, only variables of the action itself and of the previous action, reception, affected setting efficacy. The results obtained in the present study should be taken into account in the training process of both male and female volleyball players in formative stages.

    Chun-lan Guo; Ji-zhi Zhao; Jie Zhang; Hai-tao Dong

    2015-01-01

    Objective To assess the efficacy and safety of topical tacrolimus for erosive oral lichen planus (EOLP). Methods Literatures published up to December 2013 were searched from PubMed, Embase, CENTRAL, Chinese BioMedical Literature Database (CBM), and System for Information on Grey Literature in Europe (SIGLE). All randomized controlled trials (RCTs) of topical tacrolimus for EOLP which compared with other interventions or a placebo were considered in this Meta-analysis. Two researchers collected data independently. The assessment of methodological quality was based on Cochrane Handbook and the materials were analyzed with the software Revman 5.2.5. The primary outcome measures were the symptoms (e.g. pain, discomfort) complained by patients. The secondary outcome measures included the improvement rate of clinical signs assessed by the investigators and the incidence of adverse effects (e.g. clinical candidiasis). Results A total of 9 RCTs involving 476 patients were finally included. The pooled odds ratio (OR) of clinical improvement for topical tacrolimusvs. topical corticosteroids was 1.19 [95% confidence interval (CI): 0.64-2.22,I2: 44%]. Regarding to 0.1% tacrolimus and 0.03% tacrolimus, the pooledOR were 1.87 (95 %CI: 0.60-5.82) and 1.47 (95 %CI: 0.14-16.04) respectively in subgroup analysis. No serious adverse events were reported in topical tacrolimus group. Conclusions There was no evidence to support that topical tacrolimus for EOLP was more effective and safer than topical corticosteroids in this Meta-analysis. Clinical assessment criteria should be established and accepted by clinicians and researchers before further RCTs are undertaken.

  1. Efficacy and Safety of Celecoxib Therapy in Osteoarthritis: A Meta-Analysis of Randomized Controlled Trials.

    Xu, Chao; Gu, Ke; Yasen, Yalikun; Hou, Yanjie

    2016-05-01

    Osteoarthritis (OA) is the most common form of arthritis in older individuals and is among the most prevalent and disabling chronic conditions worldwide.We conducted a meta-analysis to determine the efficacy and safety of celecoxib, a cyclooxygenase-2 (COX-2) inhibitor in the treatment of osteoarthritis. Studies were pooled, and mean difference (MD), relative risk (RR), and its corresponding 95% confidence interval (CI) were calculated. Fifteen relevant articles were included for this meta-analysis study.We observed that osteoarthritis total score (MD = -4.41, 95% CI -7.27 to -1.55), pain subscale score (MD = -0.86, 95% CI -1.10 to -0.62), and function subscale score (MD = -2.90, 95% CI -5.12 to -0.67) in OA patients treatment with celecoxib was significantly improved than that with placebo. There was no significant difference in the incidence of adverse events (AEs), SAEs, and discontinuations due to AEs; however, the incidence of gastrointestinal AEs in OA patients treatment with celecoxib is significantly higher than that with placebo. For AE, the incidence of abdominal pain in OA patients with celecoxib was significantly higher than that with placebo (RR = 2.24, 95% CI: 1.40-3.58; P = 0.839, I = 0%). There was no significant difference in diarrhea, dyspepsia, headache, and nausea.This meta-analysis indicated that celecoxib treatment (200 mg orally once daily) led to significant improvement in the pain and function of osteoarthritis. However, compared with placebo control, celecoxib resulted in greater gastrointestinal AEs, especially abdominal pain after approximately 10 to 13 weeks of treatment. The current study, therefore, provides valuable information to help physicians make treatment decisions for their patients with OA.

    Postoperative pain and wound healing following tonsillectomy can result in dissatisfaction for the patient. However, there is no consensus on whether postoperatively administered honey effectively reduces morbidity after tonsillectomy. Therefore, a systematic review with a meta-analysis of the efficacy of honey as a treatment for postoperative pain and wound healing was performed. Two authors independently searched the database records (MEDLINE, SCOPUS, and Cochrane databases) dating from inception to June 2014. Studies comparing postoperative oral administration of honey with administration of placebo where the outcomes of interest were pain and wound healing on postoperative days were included. Baseline study characteristics, study quality, numbers of patients in steroid-treated and control groups, and treatment outcomes were extracted. Sufficient data for meta-analysis were retrieved from 4 trials with a total of 264 patients. We analyzed patient-reported pain scores and quantities of administered analgesics during the first 5 postoperative days. The pain score was significantly decreased in the honey-treated patients in comparison with the placebo-treated patients on postoperative day 1 only, but the analgesic intake of the honey-treated patients on the first 5 postoperative days was significantly less than that of the placebo-treated patients. In addition, honey significantly increased tonsillectomy bed wound healing in comparison with placebo during the first 2 weeks after surgery. This meta-analysis shows that postoperative administration of honey after tonsillectomy significantly reduces pain and promotes wound healing. Further trials comparing honey with good research methodology should be conducted to confirm these results.

  3. Efficacy of the third wave of behavioral therapies: a systematic review and meta-analysis.

    Ost, Lars-Göran

    2008-03-01

    During the last two decades a number of therapies, under the name of the third wave of cognitive behavior therapy (CBT), have been developed: acceptance and commitment therapy (ACT), dialectical behavior therapy (DBT), cognitive behavioral analysis system of psychotherapy (CBASP), functional analytic psychotherapy (FAP), and integrative behavioral couple therapy (IBCT). The purposes of this review article of third wave treatment RCTs were: (1) to describe and review them methodologically, (2) to meta-analytically assess their efficacy, and (3) to evaluate if they currently fulfil the criteria for empirically supported treatments. There are 13 RCTs both in ACT and DBT, 1 in CBASP, 2 in IBCT, and none in FAP. The conclusions that can be drawn are that the third wave treatment RCTs used a research methodology that was significantly less stringent than CBT studies; that the mean effect size was moderate for both ACT and DBT, and that none of the third wave therapies fulfilled the criteria for empirically supported treatments. The article ends with suggestions on how to improve future RCTs to increase the possibility of them becoming empirically supported treatments.

    2012-12-22

    Free radicals have been implicated in many diseases. They attack biological macromolecules in healthy human cells and cause protein and DNA damage along with lipid peroxidation. Present study reports the phytochemical analysis as well as free radical scavenging and antioxidant activities of Solanum xanthocarpum root extracts. Tannins, flavonoids, terpenoids, alkaloids, saponins and steroids were present in different extracts. Total flavonoid content in extracts was quantified and maximum contents were found in ethyl acetate fraction followed by chloroform and ethyl alcohol fractions, respectively. Dose dependent response was observed in metal ion chelating activity of extracts. Comparatively better chelating activity was found in polar extracts. Most of the extracts exhibited significant free radical scavenging activity in DPPH radical scavenging assay. Ethanolic and aqueous extracts accounted for about 40—50% lipid peroxidation inhibition (LPOI) in rat liver homogenate. Antioxidant activity did not show direct correlation with the amount of flavonoid contents in the extracts. However, direct correlation was observed between DPPH free radical scavenging activity and LPOI. Antioxidant activity of the extracts was compared with standard antioxidants. The differential activity observed in extracts could be attributed to the presence of other phytochemicals such as tannins and terpenoids in addition to flavonoids. The study demonstrated appreciable protective efficacy in S. xanthocarpum root extracts against free radical damage.

    2013-09-01

    The objective was to assess by simulation the efficacy of population structure analysis in plant breeding. Twelve populations and 300 inbred lines were simulated and genotyped using 100 microsatellite loci. The experimental material included populations with and without admixture, ancestry relationship and linkage disequilibrium, and with distinct levels of genetic differentiation and effective sizes. The analyses were performed using Structure software and employed all available models. For all the group number (K) tested, for both populations and inbred lines, the admixture model with correlated allelic frequencies provided the highest value for the logarithm of the marginal likelihood. Fitting appropriate model and using adequate sample size for individuals and markers, Structure was effective in identifying the correct population structure, migrants and individuals with genome from distinct populations. The linkage model did not result in an improvement in clustering relative to the admixture model with correlated allelic frequencies. The inclusion of prior information did not change the results; for some K values the analyses showed slight higher values of the marginal likelihood. The reduction in the number of individuals and markers negatively affected the results. There was a high variation in the most probable K value between the evaluated methods.

    Objective To explore application value of 99Tcm-MDP bone scanning semi-quantitative analysis in monitor-ing the osteoporosis therapy efficacy in early-stage. Methods From January 2011 to October 2013, in Central Hospital of Jinhua City of Zhejiang Province, 18 women with osteoporotic were chosen, and they were 50-72 years old. Before and 3 months after the Alendronate treatment, they were respectively checked with 99Tcm-MDP bone scanning and bone mineral density (BMD) measurement. The regions of interest (ROI) technology was used for obtaining the radioactive counts ratios (ROI ratios) of L1-L4 and femoral neck. BMD and ROI ratios of L1-L4 and femoral neck before and 3 months after the treatmnet were compared. Results The BMD of L1-L4 and femoral neck after 3-month treatment with Alendronate were higher than those before the treatment, and BMD of L3-L4 were compared with those before the treat-ment, the differences were statistically significant (P < 0.05). Bone scanning showed that ROI ratios of L1-L4 and femoral neck after the treatment were lower than those before the treatment, the differences were statistically significant (P< 0.05). Conclusion 99Tcm-MDP bone scanning semi-quantitative analysis can accurately reflect the early changes of bone metabolism after therapy, which has a potential application value in monitoring the therapy efficacy.%目的:探讨99Tcm-MDP骨显像半定量分析在骨质疏松疗效早期监测中的应用价值。方法选取2011年1月~2013年10月浙江省金华市中心医院收治的18例骨质疏松妇女,年龄50~72岁。阿仑膦酸钠治疗前及治疗后3个月分别进行99Tcm-MDP全身骨显像和骨密度值测量,利用感兴区(ROI)技术获取骨显像的L1~L4和股骨颈ROI比值并与治疗前进行对比,进行骨代谢骨质半定量分析。结果骨质疏松患者阿仑膦酸钠治疗后3个月骨密度显示,L1~L4及股骨颈骨密度值均高于治疗前,且L3和L4骨密度值与治疗前比较

    Jakob M Burgstaller

    Full Text Available BACKGROUND: Non-cardiovascular chest pain (NCCP leads to impaired quality of life and is associated with a high disease burden. Upon ruling out cardiovascular disease, only vague recommendations exist for further treatment. OBJECTIVES: To summarize treatment efficacy for patients presenting with NCCP. METHODS: Systematic review and meta-analysis. In July 2013, Medline, Web of Knowledge, Embase, EBSCOhost, Cochrane Reviews and Trials, and Scopus were searched. Hand and bibliography searches were also conducted. Randomized controlled trials (RCTs evaluating non-surgical treatments in patients with NCCP were included. Exclusion criteria were poor study quality and small sample size (<10 patients per group. RESULTS: Thirty eligible RCT's were included. Most studies assessed PPI efficacy for gastroesophageal reflux disorders (GERD, n = 10. Two RCTs included musculoskeletal chest pain, seven psychotropic drugs, and eleven various psychological interventions. Study quality was high in five RCTs and acceptable in 25. PPI treatment in patients with GERD (5 RCTs, 192 patients was more effective than placebo [pooled OR 11.7 (95% CI 5.5 to 25.0, heterogeneity I2 = 6.1%]. The pooled OR in GERD negative patients (4 RCTs, 156 patients was 0.8 (95% CI 0.2 to 2.8, heterogeneity I2 = 50.4%. In musculoskeletal NCCP (2 RCTs, 229 patients manual therapy was more effective than usual care but not than home exercise [pooled mean difference 0.5 (95% CI -0.3 to 1.3, heterogeneity I2 = 46.2%]. The findings for cognitive behavioral treatment, serotonin reuptake inhibitors, tricyclic antidepressants were mixed. Most evidence was available for cognitive behavioral treatment interventions. LIMITATIONS: Only a small number of studies were available. CONCLUSIONS: Timely diagnostic evaluation and treatment of the disease underlying NCCP is important. For patients with suspected GERD, high-dose treatment with PPI is effective. Only limited evidence was available

    Full Text Available Aim. Clinico-economical analysis of arterial hypertension (HT treatmentMaterial and methods. 78 patients with HT were involved into the study. Patients were spitted into two groups depending on HT degree. The first group – 38 patients with HT 1 degree. The second one – 40 patients with HT 2 degree. Patients of group 1 had initial antihypertensive therapy with angiotensinconverting enzyme inhibitors. If target level of blood pressure (BP had not been reached, therapy was changed on fixed combination of lisinopril and hydrochlorothiazide. Patients of group 2 had initial combined antihypertensive therapy with lisinopril and hydrochlorothiazide. If it was needed amlodipine maleat was added. Clinico-economical analysis was performed according to “cost-efficacy” approach at the end of 3 month therapy.Results. About 50% of hypertensive patients do not follow physician recommendations in out-patient practice. They decrease a dose of medicine or stop therapy themselves. More than 6% of them perform self-treatment.Conclusion. Analysis showed that therapy of patients with HT of 1 degree is economically more profitable regarding target BP achievement. It is more reasonable to start antihypertensive therapy with fixed low dose combination and add calcium antagonists if it is needed in patients with HT of 2 degree.

    2009-08-01

    Full Text Available Abstract Background Artesunate and amodiaquine (AS&AQ is at present the world's second most widely used artemisinin-based combination therapy (ACT. It was necessary to evaluate the efficacy of ACT, recently adopted by the World Health Organization (WHO and deployed over 80 countries, in order to make an evidence-based drug policy. Methods An individual patient data (IPD analysis was conducted on efficacy outcomes in 26 clinical studies in sub-Saharan Africa using the WHO protocol with similar primary and secondary endpoints. Results A total of 11,700 patients (75% under 5 years old, from 33 different sites in 16 countries were followed for 28 days. Loss to follow-up was 4.9% (575/11,700.

    2015-01-01

    Research in teacher self-efficacy has a long history that can be traced back to Bandura (1986) and has been shown to be linked to teacher performance. This article presents evidence for teacher self-efficacy in urban schools, a construct that is separate from but related to the more general construct of teacher self-efficacy. An instrument was developed and validated by a team of university faculty, urban teachers, and school administrators. The Teachers' Sense of Efficacy in Urban Schools (SEUS) is a 15-item instrument designed to address factors that are important for success in teaching in an urban environment, including working effectively with English language learners, students with disabilities, economically disadvantaged students, cultural diversity, literacy, technology, differentiation, and assessment data. The present study analyzes SEUS on multiple levels, using the Rasch partial credit model.

    2013-12-18

    The principal aims of the study were to define different profiles of cohesion and perceived efficacy in soccer players and to measure their differences in performance. The subjects were 235 soccer players in the under-18 category who played in the National League in Spain and 15 coaches whose ages ranged from 29 to 45 years. Diverse instruments to assess cohesion, perceived efficacy, and expectations of success were used in the study. Moreover, we measured playing time and performance. The results of the study proved the existence of four cohesion and efficacy profiles that presented significant differences in expectations of success, playing time, and performance. Furthermore, significant differences were found in the distribution of players in the teams as a function of performance. The main conclusion of this study is that soccer players with higher cohesion and collective efficacy levels belonged to teams that completed the season at the top-level classification. In contrast, athletes with low cohesion and collective efficacy usually played in unsuccessful teams. Coaches and sports psychologists are encouraged to promote both social and task cohesion and collective efficacy to enhance team performance.

  15. Efficacy and safety of telavancin in clinical trials: a systematic review and meta-analysis.

    Konstantinos A Polyzos

    Full Text Available INTRODUCTION: The epidemiology and antibiotic resistance of Staphylococcus aureus have evolved, underscoring the need for novel antibiotics, particularly against methicillin-resistant S. aureus (MRSA. Telavancin is a bactericidal lipoglycopeptide with potent activity against Gram-positive pathogens. OBJECTIVE: To systematically review and synthesize the available evidence from randomized controlled trials (RCTs evaluating telavancin in the treatment of patients with infections due to Gram-positive organisms with the methodology of meta-analysis. RESULTS: Six RCTs comparing telavancin with vancomycin were included; 4 (2229 patients referred to complicated skin and soft tissue infections (cSSTIs and 2 (1503 patients to hospital-acquired pneumonia (HAP. Regarding cSSTIs, telavancin and vancomycin showed comparable efficacy in clinically evaluable patients (odds ratio [OR] =1.10 [95% confidence intervals: 0.82-1.48]. Among patients with MRSA infection, telavancin showed higher eradication rates (OR=1.71 [1.08-2.70] and a trend towards better clinical response (OR=1.55 [0.93-2.58]. Regarding HAP, telavancin was non-inferior to vancomycin in terms of clinical response in two Phase III RCTs; mortality rates for the pooled trials were comparable with telavancin (20% and vancomycin (18.6%. Pooled data from cSSTIs and HAP studies on telavancin 10 mg/kg indicated higher rates of serum creatinine increases (OR=2.22 [1.38-3.57], serious adverse events (OR=1.53 [1.05-2.24], and adverse event-related withdrawals (OR=1.49 [1.14-1.95] among telavancin recipients. CONCLUSION: Telavancin might be an alternative to vancomycin in cases of difficult-to-treat MRSA infections. The potent antistaphylococcal activity of telavancin should be weighted against the potential for nephrotoxicity.

    2016-03-01

    Experiential dynamic therapy (EDT) is a subgroup of short-term psychodynamic psychotherapy (STPP) that emphasizes patients' in-session affective processing. To evaluate the efficacy of EDT for psychiatric conditions, we conducted a meta-analysis of randomized controlled trials. Twenty-eight studies published between 1978 and 2014 were included, encompassing 1,782 adult patients with mood, anxiety, personality, or mixed disorders. Across targeted outcome domains, medium-size between-groups effects (Cohen's ds ranging from 0.39 to 0.65) favored EDT over inactive controls at posttreatment and in symptom measures at follow-up. We found no differences between EDT and active treatments (e.g., medication, cognitive-behavioral therapy, manualized supportive therapy) at posttreatment, but EDT outperformed supportive therapy at follow-up (d = 0.75). In terms of within-group effect sizes, EDT was associated with large improvements in general psychiatric symptoms (d = 1.11), depression (d = 1.33), and anxiety (d = 1.09) and with small to moderate gains in the areas of interpersonal problems (d = 0.55) and global functioning (d = 0.86). Small but significant effects suggested continued improvement between posttreatment and follow-up. Heterogeneity in pre-post effects was explored in subgroup analyses, which indicated that EDT might be most effective in depressive disorders and that individual EDT had larger effects compared with group treatment. In addition, EDT performed better in higher quality studies. We conclude that EDT is a promising treatment for psychiatric conditions in adults. Further high-quality studies evaluating contemporary versions of EDT in specific psychiatric conditions are warranted.

    Background Pharmacological therapy has been considered as the first-line treatment for patients with uncomplicated benign prostatic hyperplasia (BPH). The aim of this study was to evaluate the efficacy and safety of tamsulosin compared with a placebo for treating BPH. Methods The randomized placebo-controlled trials (RCT) of tamsulosin for the treatment of BPH from all over the world were searched. PubMed, Ovid, ScienceDirect, EBSCO, CBM, and CNKI were searched, as well as a manual search of four Chinese journals: Chinese Journal of Andrology, National Journal of Andrology, Chinese Journal of Urology, and Journal of Clinical Urology was also performed. Two reviewers independently screened the studies for eligibility, evaluated the quality and extracted the data from the eligible studies, with confirmation by cross-checking. Divergences of opinions were settled by discussion. Meta-analysis was processed by Rev Man 5.0 software, fail-safe number was performed by SAS8.0 software. Results Seven RCTs involving 2455 men met the inclusion criteria. The basic characteristics of patients were comparable in all the studies. Comparing three common criteria: international prostate symptom score (IPSS)/Boyarsky symptom score, maximum flow rate (MFR), quality of life (QOL), tamsulosin was better than placebo at improving IPSS and MFR, with no significant difference in the QOL. Adverse events of tamsulosin also showed no significant difference from the placebo group (Z=1.62, P=0.10, OR=1.22, 95% CI 0.96-1.54).Conclusions Tamsulosin is better than placebo at improving IPSS and MFR. Adverse events of tamsuloisn show no significant difference compared with placebo. More high quality trials with larger samples and longer follow-up are proposed.

    The HIV/AIDS epidemic continues to grow in pockets across Asia, despite early successes at curtailing its spread in countries like Thailand. Recent evidence documents dramatic increases in incidence among risk groups and, alarmingly, the general population. This meta-analysis summarizes the sexual risk-reduction interventions for the prevention of HIV-infection that have been evaluated in Asia. Sexual risk-reduction outcomes (condom use, number of sexual partners, incident sexually transmitted infections [STI], including HIV) from 46 behavioral intervention studies with a comparison condition and available by August 2010 were included. Overall, behavioral interventions in Asia consistently reduced sexual risk outcomes. Condom use improved when interventions sampled more women, included motivational content, or did not include STI testing and treatment. Incident HIV/STI efficacy improved most when interventions sampled more women, were conducted more recently, or when they included STI counseling and testing. Sexual frequency efficacy improved more in interventions that were conducted in countries with lower human development capacities, when younger individuals were sampled, or when condom skills training was included. Behavioral interventions for reducing sexual risk in Asia are efficacious; yet, the magnitude of the effects co-varies with specific intervention and structural components. The impact of structural factors on HIV intervention efficacy must be considered when implementing and evaluating behavioral interventions. Implications and recommendations for HIV/AIDS interventions are discussed.

    2016-12-01

    Atomoxetine, a non-stimulant, is FDA approved drug used in the management of adult ADHD. Since the presentation of adult ADHD is different from the childhood onset condition, there is an urgent need to study the efficacy of atomoxetine on the different symptom domains of adult ADHD. To study the efficacy of atomoxetine in treating adult ADHD compared to placebo, we performed a Medline search for English language publications of Randomized Controlled Trials (RCTs) comparing atomoxetine to placebo for adult ADHD using the keywords "adult ADHD", "atomoxetine" and "placebo". A total of 41 RCTs were returned of which we included 13 relevant RCTs reporting data on 1824 patients with adult ADHD in the analysis. Standardized mean difference between atomoxetine and placebo for the mean baseline-to-endpoint change in total ADHD scores, impulsivity/hyperactivity and inattention scores was calculated, with a 95% confidence limit. Atomoxetine had superior efficacy than placebo on overall adult ADHD scores [-0.45; 95% CI -0.54, -0.35; overall effect pADHD compared to placebo, though the efficacy is significantly superior for inattention than hyperactivity/impulsivity.

    Full Text Available Background. Chinese medicinal herbs may be useful for the treatment of hyperuricemia, but there has been no systematic assessment of their efficacy and safety. Objectives. To systematically assess the efficacy and safety of Chinese medicinal herbs for the treatment of hyperuricemia. Methods. Six electronic databases were searched from their inception to December 2015. Randomized controlled clinical trials (RCTs were included. Cochrane criteria were applied to assess the risk of bias. Data analysis was performed using RevMan software version 5.2. Results. Eleven RCTs with 838 patients were included. There was no significant difference in serum uric acid between Chinese medicinal herbs and traditional Western medicine (SME: 0.19, 95% CI: −0.04 to 0.43; p=0.10. In terms of overall efficacy, the Chinese medicinal herbs were significantly superior to Western medicine (RR: 1.11; 95% CI: 1.04 to 1.17; p=0.0007. The Chinese medicinal herbs were better than Western medicine in reducing the adverse reactions (RR: 0.30; 95% CI: 0.15 to 0.62; p=0.001. And all these funnel plots showed unlikelihood of publishing bias. Conclusions. The results indicate that Chinese medicinal herbs may have greater overall efficacy with fewer adverse drug reactions, although the evidence is weak owing to the low methodological quality and the small number of the included trials.

    This randomized controlled study (ClinicalTrials.gov NCT02007616) investigated the maintenance of training effects of 20 1-hr non-action video game training sessions with selected games from a commercial package on several age-declining cognitive functions and subjective wellbeing after a 3-month no-contact period. Two groups of cognitively normal older adults participated in both the post-training (posttest) and the present follow-up study, the experimental group who received training and the control group who attended several meetings with the research team during the study but did not receive training. Groups were similar at baseline on demographics, vocabulary, global cognition, and depression status. Significant improvements in the trained group, and no variation in the control group had been previously found at posttest, in processing speed, attention and visual recognition memory, as well as in two dimensions of subjective wellbeing. In the current study, improvement from baseline to 3 months follow-up was found only in wellbeing (Affection and Assertivity dimensions) in the trained group whereas there was no change in the control group. Previous significant improvements in processing speed, attention and spatial memory become non-significant after the 3-month interval. Training older adults with non-action video games enhanced aspects of cognition just after training but this effect disappeared after a 3-month no-contact follow-up period. Cognitive plasticity can be induced in older adults by training, but to maintain the benefits periodic boosting sessions would be necessary.

    Background Alemtuzumab, a humanized CD52 monoclonal antibody, with its profound lymphocyte depletion property, was expected to be a promising induction therapy agent for kidney transplantation (KTx). However, currently no consensus is available about its efficacy and safety. The aim of this meta-anaiysis was to make a profound review and an objective appraisal of this issue. Methods Relevant papers were searched, essentially in the PubMed database and the Cochrane library. After a thorough review, randomized controlled trials (RCTs) comparing the outcome of KTx using alemtuzumab induction therapy (test group) with a control group were collected according to the inclusion criteria. Data of general characteristic of studies and major outcomes of Ktx were extracted and meta-analyses were performed with RevMan 4.2 software. The odds ratio (OR) with a 95% confidence intervals (CI) was the principle measurement of effect. Results Five RCTs were included. The chi square test showed no significant between-study heterogeneity, thus fixed effect model was employed. Sub-group analysis with studies including alemtuzumab induction followed by a tacrolimus-based immunosuppressive regimen showed that the acute rejection rate (ARR) was lower relative to the control (OR=0.59, 95% CI 0.34-1.01, P=0.05). However, meta-analysis with all included studies revealed that neither ARR nor patient/graft survival rates differ significantly between the test and the control group, but the cytomegalovirus (CMV) infection rate was higher in the test group (OR 2.50, 95% CI 1.22-5.12, P=0.01 ). A great number of the test group recipients safely remained on a regimen that was steroid-free and with a reduced dose of conventional immunosuppressive drugs. Conclusions Alemtuzumab induction therapy for KTx was an effective and safe protocol in the tested follow-up period. Steroid avoidance and a dose reduction of conventional immunosuppressive drugs after alemtuzumab induction therapy may have clinical

  10. Investigation of psychometric properties of the Falls Efficacy Scale using Rasch analysis in patients with hemiplegic stroke.

    2015-09-01

    [Purpose] The purpose of this study was to investigate the psychometric properties of the Falls Efficacy Scale using Rasch analysis in patients with hemiplegic stroke. [Subjects] Fifty-five community-dwelling hemiplegic stroke patients were selected as participants. [Methods] Data were analyzed using the Winsteps program (version 3.62) with the Rasch model to confirm the unidimensionality through item fit, reliability, and appropriateness of the rating scale. [Results] There were no misfit persons or items. Furthermore, infit and outfit statistics appeared adjacent. The person separation value was 3.07, and the reliability coefficient was 0.90. The reliability of all items was at an acceptable level for patients with hemiplegic stroke. [Conclusion] This was the first study to investigate the psychometric properties of the Falls Efficacy Scale using Rasch analysis. The results of this study suggest that the 6-point Falls Efficacy Scale is an appropriate tool for measuring the self-perceived fear of falling in patients with hemiplegic stroke.

    This meta-analysis estimates the overall efficacy of HIV prevention interventions to reduce HIV sexual risk behaviors and sexually transmitted infections (STIs) among heterosexual African American men. A comprehensive search of the literature published during 1988-2008 yielded 44 relevant studies. Interventions significantly reduced HIV sexual risk behaviors and STIs. The stratified analysis for HIV sexual risk behaviors indicated that interventions were efficacious for studies specifically targeting African American men and men with incarceration history. In addition, interventions that had provision/referral of medical services, male facilitators, shorter follow-up periods, or emphasized the importance of protecting family and significant others were associated with reductions in HIV sexual risk behaviors. Meta-regression analyses indicated that the most robust intervention component is the provision/referral of medical services. Findings indicate that HIV interventions for heterosexual African American men might be more efficacious if they incorporated a range of health care services rather than HIV/STI-related services alone.

    2015-01-01

    Full Text Available Background. Nocturnal enuresis (NE is recognized as a widespread health problem in young children and adolescents. Clinical researches about acupuncture therapy for nocturnal enuresis are increasing, while systematic reviews assessing the efficacy of acupuncture therapy are still lacking. Objective. This study aims to assess the effectiveness of acupuncture therapy for nocturnal enuresis. Materials and Methods. A comprehensive literature search of 8 databases was performed up to June 2014; randomized controlled trials which compared acupuncture therapy and placebo treatment or pharmacological therapy were identified. A meta-analysis was conducted. Results. This review included 21 RCTs and a total of 1590 subjects. The overall methodological qualities were low. The results of meta-analysis showed that acupuncture therapy was more effective for clinical efficacy when compared with placebo or pharmacological treatment. Adverse events associated with acupuncture therapy were not documented. Conclusion. Based on the findings of this study, we cautiously suggest that acupuncture therapy could improve the clinical efficacy. However, the beneficial effect of acupuncture might be overstated due to low methodological qualities. Rigorous high quality RCTs are urgently needed.

    2014-01-01

    The aim of this paper is to present a meta-analysis about the differential efficacy of cognitive-behavioral therapy (CBT), pharmacological and combined treatment for pediatric obsessive-compulsive disorder (OCD). The literature research and the application of the inclusion criteria enabled us to locate 18 studies, yielding a total of 24 independent comparisons between a treated (10 pharmacological, 11 CBT, and 3 combined interventions) and a control group. All types of interventions were efficacious in reducing obsessive-compulsive symptoms, with effect sizes adjusted by the type of control group of d=1.203 for CBT, d=0.745 for pharmacological treatments, and d=1.704 for mixed treatments. Depression, anxiety and other secondary responses were also improved, especially with CBT interventions. The analysis of moderator variables showed that the CBT protocol and the total of intervention hours exhibited a significant influence on the effect size. Within pharmacological treatment, clomipramine (d=1.305) was more efficacious than selective serotonin reuptake inhibitors (d=0.644), but its adverse effects were more severe. Finally, the clinical implications of the results are discussed.

    2005-08-01

    The efficacy of the Ovsynch program in improving conception and pregnancy rates was compared with untreated controls and other synchrony programs in lactating dairy cows. This meta-analysis examined 71 treatment and control comparisons extracted from 53 research papers. Programs evaluated included Ovsynch, natural breeding, single, double, or triple prostaglandin injections, Select Synch, Heat Synch, and modified Ovsynch. Pregnancy rates for Ovsynch programs did not differ significantly from those with natural breeding programs [predicted Bayesian relative risk (RR) = 1.04, 95% Bayesian credible interval = 0.36 to 3.23]. Results of Ovsynch vs. PGF(2alpha) programs showed that the risk of conception (predicted Bayesian RR = 0.89, 95% Bayesian credible interval = 0.31 to 2.64), and pregnancy rates predicted Bayesian RR = 1.11, 95% Bayesian credible interval = 0.61 to 2.13) did not differ significantly between the Ovsynch group and cows in the PGF(2alpha) group. Comparisons between Ovsynch and Select Synch demonstrated that the risk of conception (predicted Bayesian RR = 0.94, 95% Bayesian credible interval = 0.52 to 1.59), and pregnancy rates (predicted Bayesian RR = 1.08, 95% Bayesian credible interval = 0.38 to 3.09) did not differ significantly between the 2 groups. Examination of Ovsynch vs. modified Ovsynch programs showed that the risk of pregnancy in cows synchronized with modified Ovsynch was similar to those treated with Ovsynch (predicted Bayesian RR = 0.89, 95% Bayesian credible interval = 0.71 to 1.12).Meta-analyses identified that the conception and pregnancy rates obtained with the prostaglandin, Select Synch, and modified Ovsynch (including presynch and CoSynch) programs were comparable with the Ovsynch program. Modifications to the Ovsynch program such as presynchronization and timed artificial insemination at the time of second GnRH injection (CoSynch) may be an alternative for reproductive management of dairy herds where detection of estrus is less

    2012-01-01

    Objective: To assess the diagnostic efficacy of the currently most widely used indirect hemagglutination assay (IHA) and enzyme-linked immunosorbent assay (ELISA) for detection of Schistosoma japonicum human infections. Methods:A comprehensive search was undertaken from China National Knowledge Infrastructure, Wanfang Database, VIP Database, PubMed, Cochrane Library, Science Citation Index Expanded, Proquest, and the inclusion and exclusion criteria were strictly settled. The funnel plot was used to assess the publication bias, Cochran’s Q test was employed to measure the homogeneity between studies, a summary receiver operating characteristic (SROC) curve was used to compare the diagnostic accuracy between the IHA and ELISA qualitatively by means of the Weighted Least Square method, the Ordinary Least Square method and the Robust regression method, and the diagnostic odds ratio (DOR) was drawn to compare the accuracy quantitatively. Results:Out of 785 publications, 19 papers were eventually selected for analysis. Literature quality assessment indicated that minor publication bias existed in studies pertaining IHA test, but no bias was found in literatures regarding ELISA test. The heterogeneity test showed a heterogeneity between studies was present (χ2=466.07 and 34.67, both P values<0.0001). The areas under the SROC curves of IHA were all higher than that of ELISA test using the three methods (Weighted Least Square method:0.766 vs. 0.695, Ordinary Least Square method: 0.826 vs. 0.741, Robust regression: 0.815 vs. 0.715). The TPR*values for IHA and ELISA were 0.710, 0.759, 0.749, and 0.650, 0.686 and 0.666, respectively, and OR values were 5.997, 9.937, 8.893, and 3.432, 4.784 and 3.959, respectively. The DOR of IHA was 9.41 (95%CI:4.88-18.18), and 4.78 (95%CI:3.21-7.13) for ELISA. Conclusions:All above results revealed that the diagnostic performance of IHA is better than that of ELISA. However, taking into account their unsatisfactory diagnostic value in

    Full Text Available BACKGROUND: To assess the blood pressure and lipid-lowering efficacy and tolerability of 'polypills' used in cardiovascular disease prevention trials. METHODOLOGY/PRINCIPAL FINDINGS: Systematic review and meta-analysis. SEARCH STRATEGY: The Cochrane Central Register of Controlled Trials, Medline, and PubMed databases were searched for eligible trials. Study inclusion criteria: Randomised controlled trials of at least six weeks duration, which compared a 'polypill' (that included at least one anti-hypertensive and one lipid-lowering medication with a placebo (or one active component. OUTCOME MEASURES: Change from baseline in systolic and diastolic blood pressures, and total and LDL-cholesterol; discontinuation of study medication and reported adverse effects. Of 44 potentially eligible studies, six trials (including 2,218 patients without previous cardiovascular disease fulfilled the inclusion criteria. Compared with placebo, 'polypills' reduced systolic blood pressure by -9.2 mmHg (95% confidence interval (CI: -13.4, -5.0 diastolic blood pressure by -5.0 mmHg (95%CI: -7.4, -2.6, total cholesterol by -1.22 mmol/L (95%CI: -1.60, -0.84 and LDL-cholesterol by -1.02 mmol/L (95%CI: -1.37, -0.67. However, those taking a 'polypill' (vs. placebo or component were more likely to discontinue medication (20% vs 14% (Odds ratio: 1.5 (95% CI: 1.2, 1.9. There was no significant difference in reported adverse effects amongst those on a 'polypill' (36% vs. 28% (OR: 1.3 (95%CI: 0.7, 2.5. There was high statistical heterogeneity in comparisons for blood pressure and lipid-lowering but use of random-effects and quality-effects models produced very similar results. CONCLUSIONS/SIGNIFICANCE: Compared with placebo, the 'polypills' reduced blood pressure and lipids. Tolerability was lower amongst those on 'polypills' than those on placebo or one component, but differences were moderate. Effectiveness trials are needed to help clarify the status of 'polypills' in

  2. Efficacy of Supplementation with B Vitamins for Stroke Prevention: A Network Meta-Analysis of Randomized Controlled Trials.

    Hongli Dong

    Full Text Available Supplementation with B vitamins for stroke prevention has been evaluated over the years, but which combination of B vitamins is optimal for stroke prevention is unclear. We performed a network meta-analysis to assess the impact of different combinations of B vitamins on risk of stroke.A total of 17 trials (86 393 patients comparing 7 treatment strategies and placebo were included. A network meta-analysis combined all available direct and indirect treatment comparisons to evaluate the efficacy of B vitamin supplementation for all interventions.B vitamin supplementation was associated with reduced risk of stroke and cerebral hemorrhage. The risk of stroke was lower with folic acid plus vitamin B6 as compared with folic acid plus vitamin B12 and was lower with folic acid plus vitamin B6 plus vitamin B12 as compared with placebo or folic acid plus vitamin B12. The treatments ranked in order of efficacy for stroke, from higher to lower, were folic acid plus vitamin B6 > folic acid > folic acid plus vitamin B6 plus vitamin B12 > vitamin B6 plus vitamin B12 > niacin > vitamin B6 > placebo > folic acid plus vitamin B12.B vitamin supplementation was associated with reduced risk of stroke; different B vitamins and their combined treatments had different efficacy on stroke prevention. Folic acid plus vitamin B6 might be the optimal therapy for stroke prevention. Folic acid and vitamin B6 were both valuable for stroke prevention. The efficacy of vitamin B12 remains to be studied.

  3. Is the Efficacy of Milnacipran in Fibromyalgia Predictable? A Data-Mining Analysis of Baseline and Outcome Variables

    Abtroun, Lilia; Gendreau, Roger M.; Vitton, Olivier

    2016-01-01

    Objectives: Minalcipran has been approved for the treatment of fibromyalgia in several countries including Australia. Australian agency considered that the overall efficacy is moderate, although clinically significant, and could be translated into a real and strong improvement in some patients. The determination of the characteristics of patients who could benefit the most from milnacipran (MLN) is the primary objective of this manuscript. Materials and Methods: Data from the 3 pivotal phase 3 clinical trials of the Australian submission dossier were assembled into a database. A clustering method was implemented to exhibit natural groupings of homogeneous observations into clusters of efficacy outcomes and individual patients. Next, baseline characteristics were investigated using a data-mining method to determine the clinical features that may be predictive of a substantially improved effect of MLN on a set of efficacy outcomes. Results: The clustering analysis reveals 3 symptom domains: “Pain and global,” “Mood and central status,” and “Function.” We show that improvement in “Fatigue” goes with improvement in “Function.” Furthermore, the predictive data-mining analysis exhibits 4 single baseline characteristics that are associated with a substantially improved effect of MLN on efficacy outcomes. These are high pain intensity, low anxiety or catastrophizing level, absence of major sleeping problems, and physical limitations in the daily life effort. Discussion: Clustering and predictive data-mining methods provide additional insight about fibromyalgia, its symptoms, and treatment. The information is useful to physicians to optimize prescriptions in the daily practice and to regulatory bodies to refine indications. PMID:26218005

    Full Text Available Objective: Hyperbilirubinemia is one of the most devastating pathologies induced by various liver diseases. Formulae related to Paeoniae Radix Rubra (PRR at high doses have been applied to treat hyperbilirubinemia in traditional Chinese medicine. The aim of this systematic review and meta-analysis is to assess the efficacy and safety of formulae relevant to high-dose PRR in patients suffering from hyperbilirubinemia induced by viral hepatitis.Methods: We performed a meta-analysis of randomized-controlled clinical trials to evaluate the efficacy and safety of formulae that apply a high dose of PRR for hyperbilirubinemia. Seven databases were searched until April 2015. All studies were included according to detailed criteria and assessed for methodological quality. The outcome measurements were recorded for further analysis using the Revman 5.2.11 software. Results: Fifteen articles involving 1323 patients with hyperbilirubinemia were included. Formulae with high-dose PRR might promote the efficacy of either a combined application ([OR: 3.98, 95%CI (2.91, 5.43]; P<0.01 or a single application ([OR: 4.00, 95%CI (1.50, 10.68]; P<0.01 for hyperbilirubinemia. The indices of TBIL, ALT and AST significantly decreased ([MD: -75.57, 95%CI (-94.88, -56.26], [MD: -26.54, 95%CI (-36.19, -16.88] and ([MD: -28.94, 95%CI (-46.26, -11.61]; P<0.01, respectively. In addition, formulae with high-dose PRR could enhance the treatment efficacy of hyperbilirubinemia triggered by hepatitis B ([OR: 2.98, 95% CI (1.75, 5.05]; P<0.01. Furthermore, the efficacy was enhanced with an increasing dosage of PRR. Two articles reported that no side effects occurred in clinical trials, and 3 studies noted that patients presented light digestive tract symptoms.Conclusion: Formulae relevant to high-dose PRR ameliorate hyperbilirubinemia and might constitute a promising therapeutic approach. For widespread acceptance by practitioners, more rigorously designed multicenter, double

    A visual preference procedure was used to examine preferences among faces of different ethnicities (African, Asian, Caucasian, and Middle Eastern) in Chinese 3-month-old infants exposed only to Chinese faces. The infants demonstrated a preference for faces from their own ethnic group. Alongside previous results showing that Caucasian infants exposed only to Caucasian faces prefer same-race faces (Kelly et al., 2005) and that Caucasian and African infants exposed only to native faces prefer th...

    Implementing theory-based interventions is an effective way to influence physical activity (PA) behaviour in the population. This meta-analysis aimed to (1) determine the global effect of theory-based randomised controlled trials dedicated to the promotion of PA among adults, (2) measure the actual efficacy of interventions against their theoretical objectives and (3) compare the efficacy of single- versus combined-theory interventions. A systematic search through databases and review articles was carried out. Our results show that theory-based interventions (k = 82) significantly impact the PA behaviour of participants (d = 0.31, 95% CI [0.24, 0.37]). While moderation analyses revealed no efficacy difference between theories, interventions based on a single theory (d = 0.35; 95% CI [0.26, 0.43]) reported a higher impact on PA behaviour than those based on a combination of theories (d = 0.21; 95% CI [0.11, 0.32]). In spite of the global positive effect of theory-based interventions on PA behaviour, further research is required to better identify the specificities, overlaps or complementarities of the components of interventions based on relevant theories.

    The aim of the study was to assess pulmonary veins (PVs) for the presence of stenosis 3 months after cryothermal ablation (CA) with a new method of electrical isolation of PVs using contrast-enhanced 16 multidetector row computed tomography (MDCT). Twenty four patients with symptomatic atrial fibrillation underwent CA in 46 PVs. MDCT of PVs was performed before the treatment and after 3-months' follow-up. Following cryoablation, 13/24 (54%) patients showed clinical improvement and had reduced attacks of atrial fibrillation. The dimensions of the treated PVs remained unchanged: the coronal ostial diameter was 19.1{+-}2.4 preprocedural versus 18.6{+-}2.4 mm at follow-up, p>0.05; the ratio of the coronal and axial diameters at the ostium was 1.2{+-}0.2 versus 1.2{+-}0.1, p>0.05, respectively, and the coronal diameter of the proximal 10 mm was 17.1{+-}2.5 mm versus 16.5{+-}2.2 mm, p>0.05, respectively. CA is a promising technique for electrical isolation of PVs that has not been associated with stenosis at the orifice and the proximal 10 mm of the PVs after 3-months' follow-up. MDCT is a noninvasive, fast and comfortable method for assessment of PVs in a three-dimensional manner prior to ablative treatment and during the follow-up. (orig.)

    Full Text Available Background: Iron deficiency anaemia in women of reproductive age group is a major health problem in India. Objective: The present study was designed to compare the efficacy, tolerability, and cost, of three oral iron preparations among the anaemic pregnant women (n=6o of gestation (12-24 weeks. Methodology: The patients were divided into 3 groups (n=20 and treated with ferrous fumarate(100mg, ferrous bisglycinate (100mg,and carbonyl iron(100mg respectively. Follow-up was done for 3 months. Haemoglobin gm%, mean corpuscular volume and reticulocyte count were assessed at 0,1,2,3 months and serum ferritin at 0 and 3 months. Adverse effects were monitored and cost analysis was done at end of three months. Results: Significant increase in Hb was seen in all three groups (p<0.001 but, no significant difference was found between three treatments in relation to increase in Hb. Increase in ferritin with ferrous fumarate was significantly more than other treatments (p<0.05. Nausea, vomiting, epigastric pain was significantly more with ferrous fumarate but patient compliance was not affected due to them. Ferrous fumarate was the cheapest amongst all three treatments. Conclusion: It can be concluded that, ferrous fumarate still can be considered best cost effective medication with tolerable side effects for treatment as well as prevention of iron deficiency anaemia in pregnancy.

    BACKGROUND In the past decades, a large number of randomized controlled trials (RCTs) on the efficacy of ligustrazine injection combined with conventional antianginal drugs for angina pectoris have been reported. However, these RCTs have not been evaluated in accordance with PRISMA systematic review standards. The aim of this study was to evaluate the efficacy of ligustrazine injection as adjunctive therapy for angina pectoris. MATERIAL AND METHODS The databases PubMed, Medline, Cochrane Library, Embase, Sino-Med, Wanfang Databases, Chinese Scientific Journal Database, Google Scholar, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, and the Chinese Science Citation Database were searched for published RCTs. Meta-analysis was performed on the primary outcome measures, including the improvements of electrocardiography (ECG) and the reductions in angina symptoms. Sensitivity and subgroup analysis based on the M score (the refined Jadad scores) were also used to evaluate the effect of quality, sample size, and publication year of the included RCTs on the overall effect of ligustrazine injection. RESULTS Eleven RCTs involving 870 patients with angina pectoris were selected in this study. Compared with conventional antianginal drugs alone, ligustrazine injection combined with antianginal drugs significantly increased the efficacy in symptom improvement (odds ratio [OR], 3.59; 95% confidence interval [CI]: 2.39 to 5.40) and in ECG improvement (OR, 3.42; 95% CI: 2.33 to 5.01). Sensitivity and subgroup analysis also confirmed that ligustrazine injection had better effect in the treatment of angina pectoris as adjunctive therapy. CONCLUSIONS The 11 eligible RCTs indicated that ligustrazine injection as adjunctive therapy was more effective than antianginal drugs alone. However, due to the low quality of included RCTs, more rigorously designed RCTs were still needed to verify the effects of ligustrazine injection as adjunctive therapy for

    2004-01-01

    Full Text Available Introduction Both mild and severe local and systemic postvaccination reactions are seen more rarely in infants immunized with DTPa than in those immunized with DTPw vaccine. Material and methods By analysis of medical records and follow-up of patients, the authors searched for sings of adverse effects of DPT vaccines, comparing cellular and acellular vaccines in children aged from three months to five years. The results of investigation were analyzed using X2. Results Out of the total number of 940 applied vaccines, 329 were cellular and 611 were acellular. Body temperature over 38.5oC occurred in 3% of children immunized with cellular DTPw, and vomiting occurred in 0.8% of those immunized with acellular DTPa vaccine. Vomiting occurred (more than five times in 0.9% of children immunized with DPTw and in 0.32% of children immunized with DPTa. Other undesirable symptoms like swelling, redness and pain in the arm were found in 0.6% of children immunized with DPTw, and in 0.32% of children immunized with DPTa; prolonged crying (three hours or longer was registered in 0.3% of cases immunized with DPTw, and in 0.16% of immunized with DPTa vaccine. Convulsions and collapse appeared only in 0.3% of children immunized with DPTw. Discussion Our investigation shows that local and generalized undesirable postvaccination reactions occurred in 5.4% of children immunized with DPTw and in 1.64 of children immunized with DPTa. The latest clinical investigations show that acellular pertussis vaccines are successful in prevention of pertussis and that they are quite safe for infants; in our investigations, local and generalized reactions were markedly rare in children immunized with DPTa. Conclusion Undesirable postvaccination reactions after application of acellular DPT vaccines are less frequent than it is described in relevant references. The most frequent postvaccination reactions was raised body temperature (38.5oC. Convulsions and collapses were not

    Full Text Available BACKGROUND: Hepatitis C genotype 6 (HCV-6 is prevalent in Southeast Asia. Data on the efficacy of direct-acting antiviral agents in chronic HCV-6 patients is limited and pegylated interferon (Peg-IFN plus ribavirin (RBV combination therapy remains standard therapy for those patients. AIM: Meta-analysis was performed to assess the efficacy and safety of Peg-IFN plus RBV combination therapy for chronic HCV-6 patients. METHODS: Relevant studies were found by database search through Medline, Embase, Web of Science and The Cochrane Library. All published clinical trials assessing the efficacy of Peg-IFN plus RBV combination therapy for chronic HCV-6 patients were included. Sustained virological response rate (SVR was pooled. We performed additional meta-analyses to compare the SVR outcomes of 24 versus 48 weeks of treatment in four head-to-head trials. Another second meta-analysis was also conducted to compare the efficacy of combination Peg-IFN plus RBV therapy in HCV-6 versus HCV-1 patients. RESULTS: Thirteen studies met the inclusion criteria. The pooled SVR of all single arms was 75% (95% CI: 0.68-0.81. The SVR of 24 weeks treatment was significantly lower than that at 48 weeks, with a risk difference of -14% (95% CI: -0.25 to -0.02, p = 0.02. However, when restricted to the patients with rapid virological response (RVR, there was no significant effect on SVR between these two treatment groups, with a risk difference of -1% (95% CI: -0.1 to 0.07, p = 0.67. The SVR in HCV-6 patients was significantly higher than that in HCV-1 patients, with a relative risk of 1.35 (95% CI: 1.16-1.57, p<0.001. Side effects were common, but rarely caused treatment discontinuation. CONCLUSIONS: The results of this meta-analysis suggest that Peg-IFN plus RBV is effective and safe for HCV-6 patients. Shortening treatment seems to be feasible in HCV-6 patients with RVR when tolerance to treatment is poor. However, this decision should be made cautiously.

    The aim of this study was to assess the clinical efficacy and safety of oral ginger for symptomatic treatment of osteoarthritis (OA) by carrying out a systematic literature search followed by meta-analyses on selected studies. Inclusion criteria were randomized controlled trials (RCTs) comparing oral ginger treatment with placebo in OA patients aged >18 years. Outcomes were reduction in pain and reduction in disability. Harm was assessed as withdrawals due to adverse events. The efficacy effect size was estimated using Hedges' standardized mean difference (SMD), and safety by risk ratio (RR). Standard random-effects meta-analysis was used, and inconsistency was evaluated by the I-squared index (I(2)). Out of 122 retrieved references, 117 were discarded, leaving five trials (593 patients) for meta-analyses. The majority reported relevant randomization procedures and blinding, but an inadequate intention-to-treat (ITT) analysis. Following ginger intake, a statistically significant pain reduction SMD = -0.30 ([95% CI: [(-0.50, -0.09)], P = 0.005]) with a low degree of inconsistency among trials (I(2) = 27%), and a statistically significant reduction in disability SMD = -0.22 ([95% CI: ([-0.39, -0.04)]; P = 0.01; I(2) = 0%]) were seen, both in favor of ginger. Patients given ginger were more than twice as likely to discontinue treatment compared to placebo ([RR = 2.33; 95% CI: (1.04, 5.22)]; P = 0.04; I(2) = 0%]). Ginger was modestly efficacious and reasonably safe for treatment of OA. We judged the evidence to be of moderate quality, based on the small number of participants and inadequate ITT populations.

    Chemotherapy for advanced colitis-associated colorectal cancer (CAC) has been insufficiently evaluated. The goal of this study was to clarify the efficacy and safety of chemotherapy for CAC in Japan. CAC patients who were treated with chemotherapy between 2005 and 2015 were retrospectively examined. Twenty-nine patients (median age, 48 years; 23 men) were assessed. Eighteen patients had ulcerative colitis, and 11 had Crohn's disease. Three ulcerative colitis and four Crohn's disease patients were in the active disease phase. Primary tumors were located in the rectum/anus (n=16), the left colon (n=9), or the right colon (n=4). Palliative or adjuvant chemotherapy was performed in 13 and 16 patients, respectively. First-line palliative chemotherapy regimens were as follows: fluorouracil, leucovorin, and oxaliplatin (FOLFOX; n=6), FOLFOX+bevacizumab (n=3), and others (n=4). Adjuvant chemotherapy regimens were S-1 (n=7), oxaliplatin-based (n=4) and others (n=5). In palliative chemotherapy, the objective response rate was 15%, and the median progression-free survival and overall survival were 182 and 315 days, respectively. In adjuvant chemotherapy, the 5-year relapse-free survival rate was 78%. Grade 3/4 adverse events (AEs) were observed in 16 patients (55%). Active and remission inflammatory bowel disease patients suffered grade 3/4 nonhematological AEs at an incidence of 71 and 23%, respectively (Pchemotherapy for CAC exhibited sufficient efficacy, whereas modest efficacy was shown for palliative chemotherapy for CAC. AEs, particularly nonhematological AEs, were closely associated with disease activity of colitis.

    Meta-analyses that ignore the full programme of clinical trials may lead to a misleading interpretation. We did a comprehensive meta-analysis to explore the efficacy of sulbactam for the treatment of Acinetobacter baumannii complex infection. We searched electronic databases, including Pubmed and Embase up to April 24, 2016, to identify relevant published trials. Clinical trial registries were likewise searched to identify completed unpublished studies. Primary outcomes of interest were the clinical and microbiological efficacy and in-hospital mortality. Effect model was based on heterogeneity across studies. Altogether 12 observational trials, comprising about 1500 patients, were included. Compared with control group, the clinical response (OR 1.16, 95% CI 0.77-1.75), bacteriological response (OR 1.71, 95% CI 0.89-3.29) and in-hospital mortality (OR 0.76, 95% CI 0.57-1.01) of sulbactam-based therapy group achieved similar therapeutic in A. baumannii complex infection. Subgroup analysis showed the clinical response (OR 1.66, 95% CI 1.11-2.48) of A. baumannii complex infection favored high-dose sulbactam group. In conclusion, our findings suggested that the overall therapy effect of sulbactam was no more superior than alternative therapeutics. However, when taking consideration of the dose factor, we found that high dosage regimen of sulbactam showed an obvious advantage in the treatment of A. baumannii complex infection.

    The aim of this study was to evaluate the efficacy and adverse effects of lenalidomide in the treatment of intermediate-1 risk non-5q deletion [non-del (5q)] myelodysplastic syndrome (MDS). A total of 30 patients with MDS were classified through G-banding chromosome karyotype analysis and fluorescence in situ hybridization (FISH). According to the International Prognostic Scoring System scores, among the 30 patients, 23 and seven cases had scores of 0.5 and 1.0, respectively. Lenalidomide (Revlimid(®)), 10 mg/day) was administered for 21 days every 28 days. All 30 cases were treated with lenalidomide for at least three cycles, including 20 cases with four cycles. The patients did not require erythropoietin, cyclosporine or iron chelation treatments. Statistical analysis was performed using SPSS statistical software version 13.0, and comparisons among groups were conducted using a t-test. The efficacy of lenalidomide was demonstrated in patients with intermediate-1 risk non-del (5q) MDS. Peripheral blood cell counts were improved following treatment, and absolute neutrophil, haemoglobin and platelet counts increased following 2-4 cycles of treatment. All patients became stable having undergone three cycles of treatment; however, 17 patients with chromosomal abnormalities had no cytogenetic response to the treatment, as confirmed through the FISH test. Patients with intermediate-1 risk non-del (5q) MDS treated with lenalidomide did not achieve complete haematological remission, although they demonstrated haematological improvement.

    Metronidazole is frequently used against Giardia infection; however, it has been associated with significant failure rates in clearing parasites from the gut; additionally, as it should be taken for 5 to 10 days, it is associated with poor compliance, probably due to side effects. Other drugs, including tinidazole (TNZ) and albendazole (ABZ) have been included in the antigiardial armamentarium. Our aim was to assess the efficacy of ABZ compared with TNZ in Giardia infections in children. A systematic review and a meta-analysis were carried out. PubMed, Medline, EMBASE, CENTRAL, and LILACS were searched electronically until February 2015. Also relevant journals and references of studies included therein were hand-searched for randomised controlled trials (RCTs). The meta-analysis was limited to RCTs evaluating the use of ABZ compared with TNZ in children with Giardia infection. The assessed outcome was parasitological efficacy. Prediction intervals (PI) were computed to better express uncertainties in the effect estimates. Five RCTs including 403 children were included. Overall, TNZ significantly outperformed ABZ without differences between subgroups defined by ABZ dosages [relative risk, (RR) 1.61 (95% CI): (1.40-1.85); PGiardia infections in children from developing countries.

    Skinner, Marilyn D.; Lahmek, Pierre; Pham, Héloïse; Aubin, Henri-Jean

    2014-01-01

    Background Despite its success with compliant or supervised patients, disulfiram has been a controversial medication in the treatment of alcoholism. Often, study designs did not recognize a pivotal factor in disulfiram research, the importance of an open-label design. Our objectives are: (1) to analyze the efficacy and safety of disulfiram in RCTs in supporting abstinence and (2) to compare blind versus open-label studies, hypothesizing that blinded studies would show no difference between disulfiram and control groups because the threat would be evenly spread across all groups. Methods and Findings We searched PubMed, EMBASE and the Cochrane Central Register for RCTs on disulfiram use with alcoholics in comparison to any alcoholic control group. The primary outcome was defined by the authors of each trial. Additional analyses included: blind vs. open-label, with or without supervision, cocaine study or not, and type of control. Overall, the 22 included studies showed a higher success rate of disulfiram compared to controls Hedges'g = .58 (95%CI = .35–.82). When comparing blind and open-label RCTs, only open-label trials showed a significant superiority over controls g = .70 (95%CI = .46–.93). RCTs with blind designs showed no efficacy of disulfiram compared to controls. Disulfiram was also more effective than the control condition when compared to naltrexone g = .77, 95%CI = .52–1.02, to acamprosate g = .76, 95%CI = .04–1.48, and to the no disulfiram groups g = .43, 95%CI = .17–.69. Limits include: (1) a population of 89% male subjects and (2) a high but unavoidable heterogeneity of the studies with a substantial I-square in most subgroups of studies. Conclusions Blinded studies were incapable of distinguishing a difference between treatment groups and thus are incompatible with disulfiram research. Based on results with open-label studies, disulfiram is a safe and efficacious treatment compared to other abstinence

    Full Text Available BACKGROUND: Despite its success with compliant or supervised patients, disulfiram has been a controversial medication in the treatment of alcoholism. Often, study designs did not recognize a pivotal factor in disulfiram research, the importance of an open-label design. Our objectives are: (1 to analyze the efficacy and safety of disulfiram in RCTs in supporting abstinence and (2 to compare blind versus open-label studies, hypothesizing that blinded studies would show no difference between disulfiram and control groups because the threat would be evenly spread across all groups.

    Depressed mood is highly prevalent among HIV-infected individuals. Some but not all studies have found group psychotherapy to be efficacious in this population. We performed a systematic review and meta-analysis of double-blinded, randomized controlled trials to examine efficacy of group psychotherapy treatment among HIV infected with depressive symptoms. We used PubMed, the Cochrane database, and a search of bibliographies to find controlled clinical trials with random assignment to group psychotherapy or control condition among HIV infected patients with depressive symptoms. The principal measure of effect size was the standard difference between means on validated depression inventories. We identified 8 studies that included 665 subjects: 5 used cognitive behavioral therapy (CBT), 2 used supportive therapy, and 1 used coping effectiveness training. Three of the 8 studies reported significant effects. The pooled effect size from the random effects model was 0.38 (95% confidence interval [CI]: 0.23-0.53) representing a moderate effect. Heterogeneity of effect was not found to be significant (p = 0.69; I(2) = 0%). Studies reporting use of group CBT had a pooled effect size from the random effects model of 0.37 (95% CI: 0.18-0.56) and was significant. Studies reporting the use of group supportive psychotherapy had a pooled effect size from the random effects model 0.58 (95% CI: -0.05-1.22) and was nonsignificant. The results of this study suggest that group psychotherapy is efficacious in reducing depressive symptoms among, HIV-infected individuals. Of note, women were nearly absent from all studies. Future studies should be directed at addressing this disparity.

    Objective:To determine self-efficacy of HIV sero-status disclosure decisions and safer sex in HIV sero-positive persons in Jimma University Specialized Hospital, south west Ethiopia. Methods:A facility based cross sectional study design was conducted on 601 HIV positive person in Jimma University Specialized Hospital, ART clinic. Data were collected using standard pre-coded interviewer-administered questionnaire. The data were entered into SPSS version 16.0. Descriptive analysis was done to describe the characteristics of the study participants. Logistic regression was used to know the predictor of disclosure. Results:Of the 591 study participants, 564 (95.4%) were disclosed their HIV status. Married HIV patients were 22.4 times more likely practice safe sex than single HIV patients [adjusted odds ratio (AOR), 95%CI:22.4 (8.6, 58.6)]. HIV patients whose educational statuses were secondary school were 0.5 times less likely practice safe sex than HIV patients whose educational statuses were college/university [AOR, 95%CI:0.5 (0.2,0.9)]. HIV patients whose monthly income was in between 901-1 300 ETH Birr was 0.2 times less likely practice safe sex than HIV patients whose monthly income was above 1 300 ETH Birr [AOR, 95%CI: 0.2 (0.1, 0.7)]. A unit increase in total score of self-efficacy on safe sex practice the odds of practicing safe sex was increased by 2.0 [AOR, 95%CI:2.0 (1.1, 3.8)]. Conclusions: The HIV patients had high self-efficacy on disclosure, safe sex and treatment adherence. This good practice should be promoted and enhanced in different part of Ethiopia. The HIV patients had low awareness about their parents’ HIV status. Future effort should be made on awareness level about their parents’ HIV status.

    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.

    2017-01-01

    Objective To analyze the effects on pain, function, and safety of aceclofenac compared with other nonsteroidal anti-inflammatory drugs (NSAIDs) or pain relief medications in patients with osteoarthritis. Material and Methods Two investigators independently searched the database. We included randomized controlled trials evaluating efficacy and/or safety of aceclofenac compared with control interventions (NSAIDs or acetaminophen) in patients with osteoarthritis. We did not include placebo, opioid analgesics, NSAID combinations, and topical analgesics for the control groups. We summarized the efficacy data as standardized mean differences (SMD) with 95% confidence intervals (CI) and safety outcomes as risk ratios (RR) with 95% CI using the inverse variance random effect model. We assessed the heterogeneity by the I2 test. We used the GRADE approach to evaluate the quality of the evidence for all outcome parameters. Results We included 9 trials (8 double blind and 1 single blind) that evaluated pain (7 trials), function (8 trials) and safety (7 trials). We observed no significant difference in pain reduction between aceclofenac and control interventions [SMD: −0.30 (−0.62, 0.01); I2=88%; GRADE evidence- low]. Aceclofenac was more beneficial than control interventions in improving physical function [SMD: −0.27 (−0.50, −0.03); I2=88%; GRADE evidence- low]. We observed less gastrointestinal adverse events for aceclofenac than in control interventions [RR 0.69 (95% CI: 0.57, 0.83); I2=12%; GRADE evidence- moderate]. We observed no difference in overall adverse events occurrence and dropout rate between aceclofenac and control interventions. Conclusion We observed that aceclofenac was beneficial over control analgesics for function improvement and to minimize gastrointestinal adverse events. Our findings could be biased due to the heterogeneity of the sample, the fact that the trials were small and methodological issues. PMID:28293447

    2015-01-01

    Objective: The aim of this prospective study was to compare the periodontal health and the microbiological changes via real-time polymerase chain reaction (PCR) in patients treated with fixed orthodontic appliances and Invisalign® system (Align Technology, Santa Clara, California). Materials and Methods: Seventy-seven patients were enrolled in this study and divided into three groups (Invisalign® group, fixed orthodontic appliances group and control group). Plaque index, probing depth, bleeding on probing were assessed. Total biofilm mass and periodontal pathogens were analyzed and detected via real-time PCR. All these data were analyzed at the T0 (beginning of the treatment) T1 (1-month) and T2 (3 months); and statistically compared using the Mann–Whitney test for independent groups. Results: After 1-month and after 3 months of treatment there was only one sample with periodontopathic anaerobes found in patient treated using fixed orthodontic appliances. The Invisalign® group showed better results in terms of periodontal health and total biofilm mass compared to the fixed orthodontic appliance group. A statistical significant difference (P Invisalign® System show a superior periodontal health in the short-term when compared to patients in treatment with fixed orthodontic appliances. Invisalign® should be considered as a first treatment option in patients with risk of developing periodontal disease. PMID:26430371

    2012-02-01

    The main aim of this study was to investigate the predictive validity of four different optimality indexes, as well as infant perinatal status, in relation to maternal sensitivity in interaction at 3 months. The four optimality indexes comprised items related to substance abuse, psychiatric condition, relational experience and socioeconomic status (SES). Maternal sensitivity in mother-infant interaction was assessed in two different groups of mothers. One group consisted of mothers with substance abuse and psychiatric problems who underwent treatment during pregnancy. The other group of mothers had neither substance abuse nor psychiatric problems. The expectant mothers were interviewed in the third trimester of pregnancy. Medical records and meconium were obtained from the infants at birth. Three months after birth, maternal sensitivity in mother-infant interaction was assessed. Altogether 79 mother-infant dyads participated in the study. The mothers' optimality associated with relational experiences, as well as the infants' perinatal status were found to predict maternal sensitivity in mother-infant interaction at 3 months. The SES index was also significantly related to maternal sensitivity. The relation between group and maternal sensitivity was mediated by the mothers' optimality associated with relational experiences. This study points to the importance of addressing the mothers' own relational experiences and their current representations of motherhood during treatment, in order to support and enhance maternal sensitivity.

    2016-04-01

    Group psychotherapy for social anxiety disorder (SAD) is an established treatment supported by findings from primary studies and earlier meta-analyses. However, a comprehensive summary of the recent evidence is still pending. This meta-analysis investigates the efficacy of group psychotherapy for adult patients with SAD. A literature search identified 36 randomized-controlled trials examining 2171 patients. Available studies used mainly cognitive-behavioral group therapies (CBGT); therefore, quantitative analyses were done for CBGT. Medium to large positive effects emerged for wait list-controlled trials for specific symptomatology: g=0.84, 95% CI [0.72; 0.97] and general psychopathology: g=0.62, 95% CI [0.36; 0.89]. Group psychotherapy was also superior to common factor control conditions in alleviating symptoms of SAD, but not in improving general psychopathology. No differences appeared for direct comparisons of group psychotherapy and individual psychotherapy or pharmacotherapy. Hence, group psychotherapy for SAD is an efficacious treatment, equivalent to other treatment formats.

    2015-01-01

    This study aimed to analyze the clinical efficacy of different resections in treating non-muscle-invasive bladder cancer (NMIBC), including partial cystectomy, transurethral resection of bladder tumor (TURBT) and holmium laser resection of bladder tumor. Two hundred and sixteen patients were recruited with NMIBC who were available for follow-up visits in hospital, including 62 cases treated with partial cystectomy, 90 cases treated with TURBT and 64 cases with holmium laser resection. Analysis was made on the cases with tumor relapse in the two years, on operation time, blood loss, time for indwelling urinary catheter, hospital stay and complications after operation. Results were compared to the clinical efficacy of these operation patterns. It was found that the two-year relapse rate for TURBT group, partial cystectomy group and Holmium laser resection group was 41%, 31%, and 33% respectively, and the difference had no statistical significance (p>0.05). Both the TURBT group and holmium laser resection group had shorter operation time, hospital stay and time for indwelling urinary catheter as well as much less blood loss when compared with the partial cystectomy group; the difference had statistical significance (pspasm. Therefore, this study presumes that holmium laser resection and TURBT are much safer and quicker for recovery and obviously superior to the partial cystectomy.

    Collagenase Clostridium histolyticum (CCH) injection is a nonoperative treatment of hand contractures from Dupuytren disease. This study assessed the efficacy and safety of CCH in several subgroups of patients with increased surgical risk.Data were pooled from 3 randomized, placebo-controlled, double-blind trials. This analysis included 271 patients with metacarpophalangeal (n = 167) or proximal interphalangeal (n = 104) joint contractures greater than or equal to 20 degrees treated with CCH (0.58 mg collagenase per injection). Subgroups included age, sex, and diabetes status. End points included rate of clinical success (reduction in contracture to 0-5 degrees of normal) and percentage of adverse events.There was no significant difference in clinical success by age, diabetes status, or sex with 63% reaching the end point. There was no difference in adverse events among the subgroups, with peripheral edema, contusion, and injection-site hemorrhage being most common.High-risk subgroups do not demonstrate differences in efficacy or safety with CCH treatment of Dupuytren-related contractures.

    Full Text Available Generalized Anxiety Disorder (GAD is typically considered a chronic condition characterized by excessive worry. Lifetime prevalence is 4.3–5.9%, yet only a small percentage seeks treatment. GAD is treatable and in recent years internet-delivered treatment interventions have shown promise. This paper aims to systematically search for literature on internet-delivered psychological interventions for the treatment of GAD and conduct a meta-analysis to examine their efficacy. The purpose of the paper is to inform the community of researchers, program developers and practitioners in internet delivered interventions of the current state-of-the-art and research gaps that require attention. A systematic search of the literature was conducted to find all studies of internet-delivered treatments for GAD (N = 20. Using Review Manager 5 all Randomized Controlled Trials (RCTs; n = 11 that met our established eligibility criteria were included into a meta-analysis that calculated effect sizes via the standardized mean difference. Compared to the waiting-list controls, the results demonstrate positive outcomes for GAD symptoms (d = −0.91 and its central construct of pathological worry (d = −0.74. The meta-analysis supports the efficacy of internet-delivered treatments for GAD including the use of disorder-specific (4 studies and transdiagnostic treatment protocols (7 studies. Caution is advised regarding the results as the data is limited and highly heterogeneous, but revealing of what future research might be needed.

  18. Study on the absorbed fingerprint-efficacy of yuanhu zhitong tablet based on chemical analysis, vasorelaxation evaluation and data mining.

    Haiyu Xu

    Full Text Available Yuanhu Zhitong Tablet (YZT is an example of a typical and relatively simple clinical herb formula that is widely used in clinics. It is generally believed that YZT play a therapeutical effect in vivo by the synergism of multiple constituents. Thus, it is necessary to build the relationship between the absorbed fingerprints and bioactivity so as to ensure the quality, safety and efficacy. In this study, a new combinative method, an intestinal absorption test coupled with a vasorelaxation bioactivity experiment in vitro, was a simple, sensitive, and feasible technique to study on the absorbed fingerprint-efficacy of YZT based on chemical analysis, vasorelaxation evaluation and data mining. As part of this method, an everted intestinal sac method was performed to determine the intestinal absorption of YZT solutions. YZT were dissolved in solution (n = 12, and the portion of the solution that was absorbed into intestinal sacs was analyzed using rapid-resolution liquid chromatography coupled with quadruple time-of-flight mass spectrometry (RRLC-Q-TOF/MS. Semi-quantitative analysis indicated the presence of 34 compounds. The effect of the intestinally absorbed solution on vasorelaxation of rat aortic rings with endothelium attached was then evaluated in vitro. The results showed that samples grouped by HCA from chemical profiles have similar bioactivity while samples in different groups displayed very different. Moreover, it established a relationship between the absorbed fingerprints and their bioactivity to identify important components by grey relational analysis, which could predict bioactive values based on chemical profiles and provide an evidence for the quantification of multi-constituents.

    2016-01-01

    Background Traditional Helicobacter pylori (H. pylori) eradication therapies have shown efficacies below 80% in several studies, and their use has been accompanied by antibiotic-related side effects. Some recent studies have reported that supplementing standard therapies with probiotics can improve the efficacy and tolerability of Helicobacter pylori eradication therapy. Objective To assess the effects of probiotic supplementation on the eradication rates and therapy-related adverse event rates of anti-Helicobacter pylori regimens. Methods We searched PubMed, Medline, the Cochrane Central Registry of Controlled Trials and the Chinese Biomedical Database for eligible randomized controlled trials published through July, 2015. Review Manager 5.3 was used for all statistical analyses. Results Thirteen randomized controlled trials involving a total of 2306 patients were included in our analysis. Intent-to-treat (ITT) analysis performed using a fixed-effects model (test for heterogeneity I2 = 45%) showed that the pooled relative risk (RR) of eradication was significantly higher in the probiotic supplementation group than in the control group [RR 1.15, 95% confidence interval (CI): 1.10–1.20, Ppylori eradication rates. However, supplementation with Lactobacillus alone did not significantly decrease the overall incidence of side effects (RR = 0.61, 95% CI: 0.11–3.51, P = 0.58). Our study also showed that probiotic supplementation before, during or after H. pylori eradication therapy improved eradication rates, regardless of supplementation duration. Furthermore, probiotic supplementation during H. pylori treatment reduced the incidence of side effects. Conclusion Probiotic supplementation during anti-Helicobacter pylori treatment may be effective for improving H. pylori eradication rates, minimizing the incidence of therapy-related adverse events and alleviating most disease-related clinical symptoms. However, our results should be interpreted with caution because of

    Full Text Available Breastfeeding plays a pivotal role in the promotion of health and prevention of psychological problems in children. This study aimed to compare the effects of breastfeeding educational programs on the development of infants aged 1-3 months based on the model of Belief, Attitude, Subjective Norm, and Enabling Factors (BASNEF and application of acupressure on the GB-21 point. Methods: This quasi-experimental study was conducted on 150 pregnant women (gestational age: 36-41 weeks receiving care in the educational clinics affiliated to Shiraz University of Medical Sciences, Iran. Subjects were divided into two intervention groups (educational and acupressure and one control group. In intervention groups, in addition to routine prenatal care, pregnant women received training based on the BASNEF model and instructed acupressure. Mothers in the control group received only standard care during pregnancy. After the intervention, data were collected using Denver developmental screening test. Data analysis was performed in SPSS V.16 using one-way analysis of variance (ANOVA. Results: Among developmental gross motor skills, a significant difference was observed between the intervention and control groups regarding the ability to breast lift by relying on the arm (P=0.016. In terms of fine motor skills, a significant difference was observed in holding the rattle by infant (P=0.034. Moreover, time of acquiring individual and social developmental skills was higher in intervention groups compared to the control group. However, the difference was not statistically significant (P≥0.05. Therefore, no significant differences were observed between the two interventional groups in this regard (P≥0.05. Conclusion: According to the results of this study, instructed acupressure on the GB-21 pointcould improve some gross motor and fine motor skills in infants. Therefore, it is recommended that the developmental indicators in infants aged 1-3 months be evaluated in

    Full Text Available Background/Aim. The efficacy and biocompatibility of hemodialysis have a singnificant impact on dialysis patient morbidity and mortality rate. The aim of our study was to compare the efficacy and biocompatibility of different hemodialysis modalities in our patients. Methods. A total of 55 patients were included in the study, and on the basis of dialysis modality, they were divided in four groups: group I - postdilution on-line hemodiafiltration (n = 15, group II - bicarbonate high-flux polysulphone hemodialysis (n = 15, group III - bicarbonate low-flux polysulphone hemodialysis (n = 15, and groupe IV - bicarbonate cuprophane hemodialysis (n = 10. The efficacy was evaluated on the basis of urea reduction rate (URR, urea Kt/V index and serum β2-microglobuline reduction rate, and the biocompatibility was evaluated on the basis of the leukocyte count fall during the first fifteen minutes of dialysis session, and of the serum C-reactive protein (CRP level. Results. The highest mean URR was achieved in the group I (70.53 ± 6.49 %, and it was significantly higher in comparison with the average URR in the group IV (54.8 ± 6.35% (p = 0.001. The average value of urea Kt/V index in the group I (1.48 ± 0.22 was significantly higher in comparison with the average value in the groupe II 1.30 ± 0.22 (p < 0.05, group III (1.05 ± 0.22, and group IV (0.98 + 0.22 (p = 0.001. Serum β2-microglobuline reduction rate was 68.93 ± 8.25% in the group I, and 58.86 ± 7.98% in the groupe II (p = 0.01. During the first 15 minutes of hemodialysis the leukocyte number was decreased by 12.57 ± 9.35% in the group I, 13.61 ± 9.64% in the group II, 18.3 ± 13.24 in the group III and 62.3 ± 15.4 in the group IV, on average. The mean serum level of CRP was 9.4 ± 6.47 mg/l in the group IV, and less than 3.5 mg/l in the group I of the patients (p = 0.001. Conclusion. Postdilution on-line hemodiafiltration in comparison with standard hemodialysis provided the more

METHOD: A cross-sectional study of validation was carried out with 81 from community and 96 postpartum women, 54.8% of them complained of urinary leakage. An exploratory factor analysis and internal consistency analysis was performed. To check predictive capacity, we analyzed the adherence at 3 months post - intervention and compared the scores of self-efficacy between adherent and non-adherent women. Reliability was analyzed by split half procedure. RESULTS: The instrument showed α=0.923, and revealed three factors: performance expectation considering the action, performance expectation considering the preparation for action and outcome expectations. These factors accounted for 65.32% of the total variance. The instrument was able to differentiate between women who adhere and have not adhered to the exercises (U=352, p=0.013 and there was strong correlation between the two halves of the instrument (rho=0.889, p<0.001. CONCLUSION: The scale is a valid and reliable tool to measure self-efficacy to practice pelvic floor exercises.

    This study was carried out to assess and compare the efficacy of tacrolimus and clobetasol in the treatment of oral lichen planus (OLP). The Cochrane Central Register of Controlled Trials, PubMed, Scopus, Science Direct, Springer Journals, and Elsevier databases were searched using specific keywords relevant to the research question for articles published from 1998 to December 31, 2012. Finally, 15 articles that assessed the effects of tacrolimus, clobetasol, and pimecrolimus on improvements in OLP were reviewed. In addition, a meta-analysis of odds ratios (ORs) was carried out for data in 10 of the 15 articles. The results showed that the ORs for improvements in OLP in patients taking clobetasol or tacrolimus, compared with those taking placebo or other drugs, were 1.19 and 8.00, respectively. It appears that topical tacrolimus is an effective alternative to topical clobetasol and may be considered as a first-line therapy in the management of OLP.

    2011-01-01

    In the review we present detailed analysis of antihypertensive action of 3-nd generation sympatholytic moxonidine. Due to selective interaction with imidazoline I1-receptors moxonidine diminishes sympathetic activity causing lowering of peripheral vascular resistance. This leads to significant lowering of systolic and diastolic arterial pressure. Efficacy and safety of the drug has been shown both for the management of uncomplicated hypertensive crises and long term treatment of arterial hypertension (AH). Appropriateness of the use of moxonidine in patients with AH combined with diabetes mellitus, metabolic syndrome, chronic obstructive pulmonary disease has been confirmed. Moxonidine is well tolerated; its bioavailability after oral intake reaches 90%. The drug produces neither hypotensive "first dose" nor rebound effects.

    Objective: To observe the effect of balancing yin-yang needling manipulation on post-stroke upper limb spasticity and changes of electromyography (EMG) after treatment. Methods: A total of 60 eligible cases were randomly allocated into an observation group and a control group, 30 in each group. Based on routine medication, cases in the control group were treated with conventional needling manipulation, whereas cases in the observation group were treated with balancing yin-yang manipulation. After the courses of treatment were completed, the therapeutic efficacies were evaluated using modified Ashworth scale and clinical spasticity index (CSI), coupled with the integrated electromyography (IEMG) and root mean square (RMS) value of biceps in passive flexion of the elbow joint during isokinetic testing recorded with the surface EMG. Results: The total effective rate in the observation group was 86.7%, versus 53.3% in the control group, showing a statistical significance (P Conclusion:Balancing yin-yang and conventional needling manipulations can both improve upper limb spasm and reduce CSI as well as IEMG and RMS values in stroke patients;however, balancing yin-yang manipulation is better than conventional manipulation in clinical effect.

    In the present study, we reconstructed upper airway and soft palate models of 3 obstructive sleep apnea—hypopnea syndrome (OSAHS) patients with nasal obstruction. The airflow distribution and movement of the soft palate before and after surgery were described by a numerical simulation method. The curative effect of nasal surgery was evaluated for the three patients with OSAHS. The degree of nasal obstruction in the 3 patients was improved after surgery. For 2 patients with mild OSAHS, the upper airway resistance and soft palate displacement were reduced after surgery. These changes contributed to the mitigation of respiratory airflow limitation. For the patient with severe OSAHS, the upper airway resistance and soft palate displacement increased after surgery, which aggravated the airway obstruction. The efficacy of nasal surgery for patients with OSAHS is determined by the degree of improvement in nasal obstruction and whether the effects on the pharynx are beneficial. Numerical simulation results are consistent with the polysomnogram (PSG) test results, chief complaints, and clinical findings, and can indirectly reflect the degree of nasal patency and improvement of snoring symptoms, and further, provide a theoretical basis to solve relevant clinical problems.

    Nathan Ford

    Full Text Available INTRODUCTION: Lamivudine and emtricitabine are considered equivalent by several guidelines, but evidence of comparable efficacy is conflicting. METHODS: We searched two databases up to June 30 2013 to identify randomized and quasi-randomized trials in which lamivudine and emtricitabine were used as part of combination antiretroviral therapy for treatment-naïve or experienced HIV-positive adult patients. We only included trials where partner drugs in the regimen were identical or could be considered to be comparable. We allowed for comparisons between tenofovir and abacavir provided the study population did not begin treatment with a viral load >100,000 copies/ml. RESULTS: 12 trials contributed 15 different randomized comparisons providing data on 2251 patients receiving lamivudine and 2662 patients receiving emtricitabine. Treatment success was not significantly different in any of the 12 trials. In the three trials that directly compared lamivudine and emtricitabine, the relative risk for achieving treatment success was non-significant (RR 1.03 95%CI 0.96-1.10. For all trials combined, the pooled relative risk for treatment success was not significantly different (RR 1.00, 95%CI 0.97-1.02. No heterogeneity was observed (I (2 = 0. Similarly, there was no difference in the pooled relative risk for treatment failure (RR 1.08, 95%CI 0.94-1.22, I (2 = 3.4%. CONCLUSIONS: The findings of this systematic review suggest that lamivudine and emtricitabine are clinically equivalent.

    Full Text Available Objective: Aim of the present study was to evaluate the safety and efficacy of Percutaneous Nephrolithotomy (PCNL in the Galdakao- Modified Supine Valdivia (GMSV position in order to predict operative time, stone-free rate and onset of complications taking into account comorbidity, stone-related parameters and anatomic upper urinary tract abnormalities. Material and methods: A prospective evaluation of patients who underwent to PCNL in GMSV position for renal stones > 2 cm, from January 2009 to February 2015 was performed. According to the technique, upper urinary tract abnormalities, stone chemical and morphological characteristics, and patients' history were matched with operative outcome, in terms of stone-free, intervention time and incidence of perioperative complications. Results: Seventy-two cases were collected; mean operative time was 105 minutes (DS 41: staghorn stones and the presence of comorbidity resulted statistically significant variables. The complication-rate resulted in line with data showed in literature: hyperpyrexia and hemorrhage were the more frequently complications found. The overall stone-free was reached in 48 patients (67%, and it was influenced by patients’ anatomic abnormalities. Conclusions: In the treatment of renal stones, PCNL may be a safe and effective choice; nevertheless, patients’ anatomic abnormalities or staghorn-stones may influence the outcomes. Thus, a prospective study with a larger population is needed to verify our outcomes.

    2016-01-01

    Full Text Available This systematic review examines the efficacy of oral ginger for dysmenorrhea. Key biomedical databases and grey literature were searched. We included randomized controlled trials comparing oral ginger against placebo or active treatment in women with dysmenorrhea. Six trials were identified. Two authors independently reviewed the articles, extracted data, and assessed risk of bias. Discrepancies were resolved by consensus with a third reviewer. We completed a narrative synthesis of all six studies and exploratory meta-analyses of three studies comparing ginger with placebo and two studies comparing ginger with a nonsteroidal anti-inflammatory drug (NSAID. Ginger appeared more effective for reducing pain severity than placebo. The weighted mean difference on a 10 cm visual analogue scale was 1.55 cm (favoring ginger (95% CI 0.68 to 2.43. No significant difference was found between ginger and mefenamic acid (an NSAID. The standardized mean difference was 0 (95% CI −0.40 to 0.41. Available data suggest that oral ginger could be an effective treatment for menstrual pain in dysmenorrhea. Findings, however, need to be interpreted with caution because of the small number of studies, poor methodological quality of the studies, and high heterogeneity across trials. The review highlights the need for future trials with high methodological quality.

    Heterocyclic dications are receiving increasing attention as targeted inhibitors of transcription factors. While many dications act as purely competitive inhibitors, some fail to displace protein efficiently at drug concentrations expected to saturate their DNA target. To achieve a mechanistic understanding of these non-competitive effects, we used a combination of dications, which are intrinsically fluorescent and spectrally-separated fluorescently labeled DNA to dissect complex interactions in multi-component drug/DNA/protein systems. Specifically, we interrogated site-specific binding by the transcription factor PU.1 and its perturbation by DB270, a furan-bisbenzimidazole-diamidine that strongly targets PU.1 binding sites yet poorly inhibits PU.1/DNA complexes. By titrating DB270 and/or cyanine-labeled DNA with protein or unlabeled DNA, and following the changes in their fluorescence polarization, we found direct evidence that DB270 bound protein independently of their mutual affinities for sequence-specific DNA. Each of the three species competed for the other two, and this interplay of mutually dependent equilibria abrogated DB270's inhibitory activity, which was substantively restored under conditions that attenuated DB270/PU.1 binding. PU.1 binding was consistent with DB270's poor inhibitory efficacy of PU.1 in vivo, while its isosteric selenophene analog (DB1976), which did not bind PU.1 and strongly inhibited the PU.1/DNA complex in vitro, fully antagonized PU.1-dependent transactivation in vivo.

    Background Skin and soft tissue infections (SSTIs) are significant indications for antibiotic treatment. Daptomycin, a novel antibiotic, has been registered and licensed to be used in the treatment of these infections. However, its efficacy and safety remain controversial. Objective The objective of this study was to conduct a systematic review with trial sequential analysis (TSA) to evaluate the efficacy and safety of daptomycin for the treatment of SSTIs and to analyze whether the available sample size has been large enough and is conclusive. Methods PubMed, the Cochrane Library, and EMBASE were searched for published randomized controlled trials (RCTs) that compared daptomycin with other antibiotics in adult patients with SSTIs up to February 2016. Results This meta-analysis included eight randomized controlled trials (n=2,002). There was no difference in either the clinical success rate (intention-to-treat population: relative risk [RR] =1.04, 95% confidence interval [CI] =0.99–1.10, P=0.12; clinically evaluable population: RR =1.00, 95% CI =0.97–1.04, P=0.82) or the microbiological success rate (RR =1.00, 95% CI =0.95–1.06, P=0.92) between the daptomycin and comparator groups for treating SSTIs, which was confirmed by TSA. Compared with vancomycin, daptomycin exhibited no advantage in increasing the clinical success rate (RR =1.03, 95% CI =0.95–1.13, P=0.47), and this was also confirmed by TSA. All-cause mortality, overall treatment-related adverse events, and creatine phosphokinase events were similar between these two groups. Conclusion Daptomycin and comparator drugs are equally efficacious with regard to clinical and microbiological success for patients with SSTIs, and TSA showed that no additional randomized controlled trials are required. Although daptomycin is a good alternative when other antibiotics are contraindicated for patients with SSTIs and it can serve as a first-line treatment for SSTIs, clinicians should be aware of potential adverse

Relative risk (RR, standardized mean difference (SMD, 95% confidence intervals (95% CIs, and numbers needed to treat/harm (NNT/NNH were calculated.Results: We identified four relevant RCTs (total n=1,860, two placebo-controlled trials, one noninferiority trial comparing AOM to oral aripiprazole (OA, and one including therapeutic doses of AOM and OA, as well as an AOM dose below therapeutic threshold (control arm. AOM was superior to placebo for decreasing Positive and Negative Syndrome Scale (PANSS total scores (SMD =-0.65, 95% CI =-0.90 to -0.41, n=1,126. However, PANSS total scores did not differ significantly between pooled AOM and OA groups. The pooled AOM group showed significantly lower incidence of all-cause discontinuation (RR =0.54, 95% CI =0.41–0.71, n=1,139, NNH =4 and inefficacy (RR =0.28, 95% CI =0.21–0.38, n=1,139, NNH =5 than placebo, but was not superior to placebo regarding discontinuation due to adverse events (AEs or death. The AOM group exhibited a lower incidence of all-cause discontinuation than OA (RR =0.78, 95% CI =0.64–0.95, n=986, NNH =14, but there were no intergroup differences in discontinuation due to inefficacy, AEs, or death. There were no significant differences in extrapyramidal symptoms scale scores between AOM and placebo or between AOM and OA. AOM resulted in higher weight gain than placebo (SMD =0.41, 95% CI =0.18–0.64, n=734 but lower than OA (SMD =-0.16, 95% CI =-0.29 to -0.02, n=847.Conclusion: AOM has antipsychotic efficacy and low risk of discontinuation due to AEs.

    Introduction Consensus on the best treatment regimens for patients with isoniazid-resistant TB is limited; global treatment guidelines differ. We undertook a systematic review and meta-analysis using mixed-treatment comparisons methodology to provide an up-to-date summary of randomised controlled trials (RCTs) and relative regimen efficacy. Methods Ovid MEDLINE, the Web of Science and EMBASE were mined using search terms for TB, drug therapy and RCTs. Extracted data were inputted into fixed-effects and random-effects models. ORs for all possible network comparisons and hierarchical rankings for different regimens were obtained. Results 12 604 records were retrieved and 118 remained postextraction, representing 59 studies—27 standalone and 32 with multiple papers. In comparison to a baseline category that included the WHO-recommended regimen for countries with high levels of isoniazid resistance (rifampicin-containing regimens using fewer than three effective drugs at 4 months, in which rifampicin was protected by another effective drug at 6 months, and rifampicin was taken for 6 months), extending the duration of rifampicin and increasing the number of effective drugs at 4 months lowered the odds of unfavourable outcomes (treatment failure or the lack of microbiological cure; relapse post-treatment; death due to TB) in a fixed-effects model (OR 0.31 (95% credible interval 0.12–0.81)). In a random-effects model all estimates crossed the null. Conclusions Our systematic review and network meta-analysis highlight a regimen category that may be more efficacious than the WHO population level recommendation, and identify knowledge gaps where data are sparse.

    The recent availability of human induced pluripotent stem cells (hiPSCs) holds great promise as a novel source of human-derived neurons for cell and tissue therapies as well as for in vitro drug screenings that might replace the use of animal models. However, there is still a considerable lack of knowledge on the functional properties of hiPSC-derived neuronal networks, thus limiting their application. Here, upon optimization of cell culture protocols, we demonstrate that both spontaneous and evoked electrical spiking activities of these networks can be characterized on-chip by taking advantage of the resolution provided by CMOS multielectrode arrays (CMOS-MEAs). These devices feature a large and closely-spaced array of 4096 simultaneously recording electrodes and multi-site on-chip electrical stimulation. Our results show that networks of human-derived neurons can respond to electrical stimulation with a physiological repertoire of spike waveforms after 3 months of cell culture, a period of time during which the network undergoes the expression of developing patterns of spontaneous spiking activity. To achieve this, we have investigated the impact on the network formation and on the emerging network-wide functional properties induced by different biochemical substrates, i.e., poly-dl-ornithine (PDLO), poly-l-ornithine (PLO), and polyethylenimine (PEI), that were used as adhesion promoters for the cell culture. Interestingly, we found that neuronal networks grown on PDLO coated substrates show significantly higher spontaneous firing activity, reliable responses to low-frequency electrical stimuli, and an appropriate level of PSD-95 that may denote a physiological neuronal maturation profile and synapse stabilization. However, our results also suggest that even 3-month culture might not be sufficient for human-derived neuronal network maturation. Taken together, our results highlight the tight relationship existing between substrate coatings and emerging network

  18. Efficacy and Safety of HER2-Targeted Agents for Breast Cancer with HER2-Overexpression: A Network Meta-Analysis.

    Qiuyan Yu

    Full Text Available Clinical trials of human epidermal growth factor receptor 2 (HER2-targeted agents added to standard treatment have been efficacious for HER2-positive (HER2+ advanced breast cancer. To our knowledge, no meta-analysis has evaluated HER2-targeted therapy including trastuzumab emtansine (T-DM1 and pertuzumab for HER2-positive breast caner and ranked the targeted treatments. We performed a network meta-analysis of both direct and indirect comparisons to evaluate the effect of adding HER2-targeted agents to standard treatment and examined side effects.We performed a Bayesian-framework network meta-analysis of randomized controlled trials to compare 6 HER2-targeted treatment regimens and 1 naïve standard treatment (NST, without any-targeted drugs in targeted treatment of HER2+ breast cancer in adults. These treatment regimens were T-DM1, LC (lapatinib, HC (trastuzumab, PEC (pertuzumab, LHC (lapatinib and trastuzumab, and PEHC (pertuzumab and trastuzumab. The main outcomes were overall survival and response rates. We also examined side effects of rash, LVEF (left ventricular ejection fraction, fatigue, and gastrointestinal disorders, and performed subgroup analysis for the different treatment regimens in metastatic or advanced breast cancer.We identified 25 articles of 21 trials, with data for 11,276 participants. T-DM1 and PEHC were more efficient drug regimens with regard to overall survival as compared with LHC, LC, HC and PEC. The incidence of treatment-related rash occurs more frequently in the patients who received LC treatment regimen than PEHC and T-DM1 and HC. In subgroup analysis, T-DM1 was associated with increased overall survival as compared with LC and HC. PEHC was associated with increased overall response as compared with LC, HC, and NST.Overall, the regimen of T-DM1 as well as pertuzumab in combination with trastuzumab and docetaxel is efficacious with fewer side effects as compared with other regimens, especially for advanced HER2

  19. Theory-based analysis of clinical efficacy of triptans using receptor occupancy

    2014-01-01

    Background Triptans, serotonin 5-HT1B/1D receptor agonists, exert their action by targeting serotonin 5-HT1B/1D receptors, are used for treatment of migraine attack. Presently, 5 different triptans, namely sumatriptan, zolmitriptan, eletriptan, rizatriptan, and naratriptan, are marketed in Japan. In the present study, we retrospectively analyzed the relationships of clinical efficacy (headache relief) in Japanese and 5-HT1B/1D receptor occupancy (Φ1B and Φ1D). Receptor occupancies were calculated from both the pharmacokinetic and pharmacodynamic data of triptans. Methods To evaluate the total amount of exposure to drug, we calculated the area under the plasma concentration-time curve (AUCcp) and the areas under the time curves for Ф1B and Ф1D (AUCФ1B and AUCФ1D). Moreover, parameters expressing drug transfer and binding rates (A cp , A Ф 1B , A Ф 1D ) were calculated. Results Our calculations showed that Фmax1B and Фmax1D were relatively high at 32.0-89.4% and 68.4-96.2%, respectively, suggesting that it is likely that a high occupancy is necessary to attain the clinical effect. In addition, the relationships between therapeutic effect and AUCcp, AUCΦ1B, AUCΦ1D, and A cp  · AUCcp differed with each drug and administered form, whereas a significant relationship was found between the therapeutic effect and A Φ 1B  · AUCΦ1B or A Φ 1D  · AUCΦ1D that was not affected by the drug and the form of administration. Conclusions These results suggest that receptor occupancy can be used as a parameter for a common index to evaluate the therapeutic effect. We considered that the present findings provide useful information to support the proper use of triptans. PMID:25488888

    Full Text Available PURPOSE: The study here presented was done to test the technical reliability and immediate efficacy of the Acucise device using a standardized technique. MATERIALS AND METHODS: 56 Acucise procedures were performed in pigs by a single surgeon who used a standardized technique: insert 5F angiographic catheter bilaterally up to the midureter, perform retrograde pyelogram, Amplatz super-stiff guidewire is advanced up to the level of the renal pelvis, angiographic catheters are removed, Acucise catheter balloon is advanced to the ureteropelvic junction (UPJ level, the super-stiff guide-wire is removed and the contrast medium in the renal pelvis is aspirated and replaced with distilled water, activate Acucise at 75 watts of pure cutting current, keep the balloon fully inflated for 10 minutes, perform retrograde ureteropyelogram to document extravasation, remove Acucise catheter and pass an ureteral stent and remove guide-wire. RESULTS: In no case did the Acucise device present malfunction. The electrocautery activation time was 2.2 seconds (ranging from 2 to 4 seconds. The extravasation of contrast medium, visible by fluoroscopy, occurred in 53 of the 56 cases (94.6%. In no case there was any evidence of intraoperative hemorrhage. CONCLUSIONS: This study revealed that performing Acucise endopyelotomy routinely in a standardized manner could largely preclude intraoperative device malfunction and eliminate complications while achieving a successful incision in the UPJ. With the guidelines that were used in this study, we believe that Acucise endopyelotomy can be completed successfully and safely in the majority of selected patients with UPJ obstruction.

    @@ Sedation may result in reduction in pain during transrectal ultrasound(TRUS)-guided prostate biopsies.We aimed to evaluate the efficacy and safety of a combination of propofol and remifentanil infusion during TRUS-guided prostate biopsy and the related increases in health care costs.From January to September 2010,100 men undergoing a transrectal prostate biopsy were randomized into two groups.In Group 1,[50]patients received a combined infusion of propofol and remifentanil; in Group 2,[50]patients received lidocaine jelly.After TRUS-guided biopsies were performed,pain and patient satisfaction were evaluated by a 10-point visual analog scale (VAS),and a cost-related patient satisfaction questionnaire was completed by all patients.Patients were also asked whether they would be willing to undergo repeat biopsy by the same method.Patients in Group 1 showed a significantly lower VAS score than those in Group 2 (mean VAS score: 0.9士1.1 versus 6.312.5; P<0.001).In addition,the patient satisfaction scale was significantly higher in Group 1(P=0.002).Although the overall cost was significantly higher in Group 1(P=0.006),patient satisfaction scales considering cost were also higher in this group (P=0.009).A combination of propofol and remifentanil is a safe and effective way to decrease patient pain and increase patient satisfaction during TRUS-guided prostate biopsy.Although the costs were higher in the group that received sedation,as expected,the patients exhibited heightened satisfaction and willingness to repeat biopsies by the same method.

    2010-01-01

    Full Text Available Using item response theory (IRT, we examined the Rheumatoid Arthritis Self-efficacy scale (RASE collected from a People with Arthritis Can Exercise RCT (346 participants and 2 subscales of the Arthritis Self-efficacy scale (ASE collected from an Active Living Every Day (ALED RCT (354 participants to determine which one better identifies low arthritis self-efficacy in community-based adults with arthritis. The item parameters were estimated in Multilog using the graded response model. The 2 ASE subscales are adequately explained by one factor. There was evidence for 2 locally dependent item pairs; two items from these pairs were removed when we reran the model. The exploratory factor analysis results for RASE showed a multifactor solution which led to a 9-factor solution. In order to perform IRT analysis, one item from each of the 9 subfactors was selected. Both scales were effective at measuring a range of arthritis SE.

  4. Using Meta-analysis to Compare the Efficacy of Medications for Attention-Deficit/Hyperactivity Disorder in Youths.

    2009-12-01

    Medications used to treat attention-deficit/hyperactivity disorder (ADHD) have been well researched, but comparisons among agents are hindered by the absence of head-to-head clinical trials. By using meta-analysis, we sought to compare the efficacy of these medications for the symptoms of ADHD. We analyzed published literature on the pharmacotherapy of ADHD to describe the variability of drug-placebo effect sizes and conducted a literature search to identify double-blind, placebo-controlled studies of youths with ADHD that were published after 1979. Meta-analysis regression was used to assess the influence of the medication type on drug effects. We also assessed for publication bias.Thirty-two trials met our criteria and were included in this meta-analysis. These trials involved 16 drugs using 20 different outcome measures of ADHD behaviors. The effect sizes for immediate-release stimulants and long-acting stimulants were similar and were greater than the effect sizes for non-stimulants. There was no evidence of publication bias.Although nearly all of the ADHD medications had significant effects, we found substantial variability. When translated into the costs of treating large numbers of patients, these effect sizes have implications for formulary medication choices.

    Microbial penetration inside the implants internal cavity produces a bacterial reservoir that is associated with an area of inflamed connective tissue facing the fixture-abutment junction. The aim of this clinical trial is to evaluate the effectiveness of a 1 percent chlorhexidine gel on the internal bacterial contamination of implants with screw-retained abutments and on the level of AST secreted in peri-implant crevicular fluid. Twenty-five patients (aged 29 to 58 years) each received one implant. Three months after the end of the restorative treatment, and immediately after a clinical and radiographic examination and the abutment removal, microbiological samples were obtained from the internal part of each fixture and biochemical samples were collected by peri-implant sulci. The patients were then divided into two groups: the control (CG; n=10) and test (TG; n=15) groups. The CG had the abutment screwed into place and the crown cemented without any further intervention. In contrast, before the abutment placement and screw tightening, the TG had the internal part of the fixture filled with a 1 percent chlorhexidine gel. Three months later, the same clinical, microbiological and biochemical procedures were repeated in both groups. Total bacterial count, specific pathogens and AST activity were detected. The clinical parameters remained stable throughout the study. From baseline to the 3-month examination, the total bacterial counts underwent a significant reduction only in the TG. In contrast, the AST activity showed a significant increase in the CG. The administration of a 1% chlorhexidine gel appears to be an effective method for the reduction of bacterial colonization of the implant cavity and for safeguarding the health status of peri-implant tissue over a 3-month administration period.

    Pilot studies of combined therapies treating benign nodular goiters reported promising results. The aim of this study was to investigate the effectiveness of combined microwave ablation (MWA) and radioiodine therapy (RIT) with a special focus on thyroid function at the 3-month follow-up. 15 patients (median age: 55 years) with a large goiter and benign thyroid nodules or Graves' disease were treated with the combined therapy. Serum levels of triiodothyronine (T3), thyroxine (T4), thyrotropin (TSH), thyroglobuline (Tg) and, additionally, antibody levels against thyroglobulin (TgAb), thyrotropin receptors (TRAb) and thyroid peroxidase (TPOAb) were measured at enrollment, post MWA and at the 3-month follow-up (3MFU). Furthermore, the goiter volume, I-131 dose and hospitalization time were analyzed to evaluate effectiveness. MWA was operated under local anesthesia with a system working in a wavelength field of 902 to 928 MHz. TSH, T4, T3 and Tg did not change at 3MFU, except for in two patients in whom the initial TSH levels improved to normal thyroid functioning levels at follow-up. One of the patients developed a high TRAb-level that receded back into the normal range. At 3MFU, the combined therapy showed a mean thyroid volume reduction of 26.4 ml ± 7.9 ml (30.5 % ± 4.6 % (p < 0.05)). By utilizing the combined therapy, administered activity could be reduced by 26.6 % ± 4.8 % (p < 0.05) and hospitalization time by 30.9 % ± 19.9 % (p < 0.05). The data confirmed the effectiveness of the combination of MWA with RIT. The combined therapy is an innovative and conservative approach and could become a safe alternative to surgery for the treatment of very large benign nodular goiters. Due to the short follow-up and the limited number of patients, further studies will be necessary.

    Background The challenges of advanced cancer have health implications for patients and their family caregivers from diagnosis through end-of-life. The nature of the patient/caregiver experience suggests that their mental and physical health may be interdependent, but limited empirical evidence exists. Purpose This study used Social Cognitive Theory as a framework to investigate individual and interpersonal influences on patients’ and their family caregivers’ mental health, physical health, and self-efficacy as individuals to manage the challenges of advanced disease over time. Methods Patients and caregivers (484 patient-caregiver dyads) completed surveys at baseline, 3 months and 6 months. Longitudinal dyadic analysis techniques were used to examine (i) the influence that patients and caregivers had on their own mental health, physical health, and self-efficacy (actor effects) and (ii) the influence that they had on each other’s health outcomes (partner effects). We also examined the influence of self-efficacy on mental and physical health over time. Results Consistent with our hypotheses, each person’s mental health, physical health, and self-efficacy had significant effects on their own outcomes over time (actor effects). Patients and caregivers influenced one another’s mental and physical health (partner effects), but not their self-efficacy. In addition, patients and caregivers with higher self-efficacy had better mental health, and their partners had better physical health. Conclusions Patient and caregiver mental and physical health were interdependent. Each person’s cancer-related self-efficacy influenced their own mental and physical health. However, a person’s self-efficacy did not influence the other person’s self-efficacy. PMID:26489843

    2016-01-01

    Introduction Helicobacter pylori colonization is present in half of the world’s population and can lead to numerous gastrointestinal diseases if left untreated, including peptic ulcer disease and gastric cancer. Although concurrent triple therapy remains the recommended treatment regimen for H. pylori eradication, its success rate and efficacy have been declining. Recent studies have shown that the addition of probiotics can significantly increase eradication rates by up to 50%. This meta-analysis examines the impact of probiotic supplementation on the efficacy of standard triple therapy in eradicating H. pylori. Methods A comprehensive literature search was conducted using PubMed, Cochrane Central Registry of Controlled Trials, and Google Scholar (time of inception to 2016) to identify all published randomized control trials (RCTs) assessing the use of probiotics in addition to triple therapy for the treatment of H. pylori. Searches were conducted using the keywords “probiotics”, “triple therapy”, and “Helicobacter pylori”. RCTs comparing the use of probiotics and standard triple therapy with standard triple therapy alone for any duration in patients of any age diagnosed with H. pylori infection were included. H. pylori eradication rates (detected using urea breath test or stool antigen) were analyzed as-per-protocol (APP) and intention-to-treat (ITT). Results A total of 30 RCTs involving 4,302 patients APP and 4,515 patients ITT were analyzed. The addition of probiotics significantly increased eradication rates by 12.2% (relative risk [RR] =1.122; 95% confidence interval [CI], 1.091–1.153; PProbiotics were beneficial among children and adults, as well as Asians and non-Asians. No significant difference was observed in efficacy between the various types of probiotics. The risk of diarrhea, nausea, vomiting, and epigastric pain was also reduced. Conclusion The addition of probiotics is associated with improved H. pylori eradication rates in both

    The objective of this meta-analysis was to evaluate the effects of coenzyme Q10 (CoQ10) for the treatment of Parkinson's disease (PD) patients in order to arrive at qualitative and quantitative conclusions about the efficacy of CoQ10. Databases searched included PubMed, Google scholar, CNKI, Wan-Fang, and the Cochrane Library from inception to March 2016. We only included sham-controlled, randomized clinical trials of CoQ10 intervention for motor dysfunction in patients with PD. Relevant measures were extracted independently by two investigators. Weighted mean differences (WMD) were calculated with random-effects models. Eight studies with a total of 899 patients were included. Random-effects analysis revealed a pooled WMD of 1.02, indicating no significant difference when CoQ10 treatment compared with placebo in terms of UPDRS part 3 (p = 0.54). Meanwhile, the effect size of UPDRS part 1, UPDRS part 2, and total UPDRS scores were similar in CoQ10 group with in placebo group (p > 0.05). Moreover, we found CoQ10 was well tolerated compared with placebo group. Subgroup analysis showed that the effect size of CoQ10 in monocentric studies was larger than in multicenter studies. Using the GRADE criteria, we characterized the quality of evidence presented in this meta-analysis as moderate to high level. The current meta-analysis provided evidence that CoQ10 was safe and well tolerated in participants with PD and no superior to placebo in terms of motor symptoms. According to these results, we cannot recommend CoQ10 for the routine treatment of PD right now.

    Full Text Available BACKGROUND: Multi-drug resistance among Acinetobacter baumannii increases the need for polymyxins. We conducted a meta-analysis aimed to assess the efficacy and safety of polymyxins for the treatment of Acinetobacter baumannii infection. METHODS: We searched PUBMED, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL, CNKI, Chinese Biomedical Literature Database up to November 1, 2013, to identify published studies, and we searched clinical trial registries to identify completed unpublished studies. Randomized controlled trials and cohort studies were considered for inclusion. Data were extracted on clinical response, microbiological response, mortality, length of stay and adverse events. RESULTS: 12 controlled studies, comparing 677 patients, were included. Although clinical (odds ratio 1.421, 95% confidence interval 0.722-2.797 and microbiological (OR 1.416, 95% CI 0.369-5.425 response rates favored the polymyxins group, these differences were not significant. Treatment with polymyxins vs. controls did not affect hospital mortality (OR 0.506, 95% CI 0.101-2.536, lengths of hospital stay (standard mean difference -0.221, 95% CI 0.899-0.458 or nephrotoxicity (OR 1.192, 95% CI 0.436-3.261. The combination of polymyxins with other antibiotics achieved similar clinical response rates to its monotherapy regimen (OR 0.601, 95% CI 0.320-1.130. CONCLUSIONS: Our results suggest that polymyxins may be as safe and as efficacious as standard antibiotics for the treatment of A. baumannii infection. There is no strong evidence that combination regimen of polymyxins is superior to monotherapy regimen.

    2017-01-01

    Background To assess the efficacy and safety of oxcarbazepine (OXC) in the treatment of children with epilepsy. Methods Randomized controlled trials (RCTs) published in PubMed, Embase, Web of Science, Cochrane Library, Scopus, SinoMed (Chinese BioMedical Literature Service System, China), and Chinese National Knowledge Infrastructure (China) database were systematically reviewed. Eligible studies were those that compared the efficacy and safety of OXC with other antiepileptic drugs in epilepsy. Risk ratio (RR) with 95% confidence intervals (95% CIs) was calculated using fixed-effects or random-effects model. Results Eleven RCTs with a total of 1,241 patients met the inclusion criteria and were included in this meta-analysis. Compared with other antiepileptic drugs (sodium valproate, levetiracetam, phenytoin, and placebo), OXC was associated with similar seizure-free rate (RR =1.06, 95% CI: 0.94, 1.20; P=0.366) and percentage reduction from baseline in seizure frequency (for ≥75% reduction: RR =1.15, 95% CI: 0.88, 1.49; P=0.310; for 50%–75% reduction: RR =1.12, 95% CI: 0.90, 1.39; P=0.301; for <50% reduction: RR =0.79, 95% CI: 0.56, 1.12; P=0.179). Moreover, patients treated with OXC had a comparable incidence of adverse events compared with those treated with other antiepileptic drugs (RR =1.01, 95% CI: 0.92, 1.11; P=0.760). Conclusion OXC showed similar effects and safety as other antiepileptic drugs in the treatment of children with epilepsy. Further well-conducted, large-scale RCTs are needed to validate these findings. PMID:28293110

    Full Text Available Objective: To evaluate the efficacy and safety of canagliflozin in combination therapy among patients with type 2 diabetes mellitus with inadequate glycemic control. Methods: Two review authors independently searched for the relevant randomized controlled clinical trials from the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, IndMed, LILACS, and clinical trials registry www.clinicaltrials.gov. Primary outcomes for this review included: change in hemoglobin A1c (HbA1c levels, fasting plasma glucose (FPG levels and risk of occurrence of genital mycotic infections at 26 weeks. We combined results using mean difference (MD for continuous data, and risk ratio (RR for dichotomous data. Results: Of the 124 identified reports, five RCTs with 3565 participants were eligible for the meta-analysis. All included studies had compared canagliflozin 100 mg and 300 mg once daily with placebo or sitagliptin 100 mg once daily. We judged that most of the studies had low risk of bias or unclear risk of bias in five major domains. Canagliflozin 300 mg once daily led to a significant decrease in HbA1c levels (IV Fixed -0.77, 95% CI [-0.90, -0.64] P < 0.00001 and FPG levels (IV Fixed -2.08; 95% CI [-2.32, -1.84], P <0.00001, body weight, systolic blood pressure and triglyceride levels after 26 weeks as compared to placebo. There was a also a significant difference in the efficacy of canagliflozin 300 mg and sitagliptin 100 mg once daily in favour of canagliflozin. Both doses of canagliflozin led to genital mycotic infections among males and females, urinary tract infections, pollakiuria, polyuria and postural dizziness. Conclusions: Canagliflozin significantly decreases HbA1c and FPG levels and body weight as compared to placebo among patients with inadequate glycemic control with an earlier regime of glucose lowering agents. Long term safety studies are required to evaluate the incidence of adverse events.

    Full Text Available Abstract Background Recent systematic reviews on psychological therapies of fibromyalgia syndrome (FMS did not consider hypnosis/guided imagery (H/GI. Therefore we performed a systematic review with meta-analysis of the efficacy of H/GI in FMS. Methods We screened http://ClinicalTrials.gov, Cochrane Library, MEDLINE, PsycINFO and SCOPUS (through December 2010. (Quasi- randomized controlled trials (CTs comparing H/GI with controls were analyzed. Outcomes were pain, sleep, fatigue, depressed mood and health-related quality of life (HRQOL. Effects were summarized using standardized mean differences (SMD. Results Six CTs with 239 subjects with a median of 9 (range 7-12 H/GI-sessions were analysed. The median number of patients in the H/GI groups was 20 (range 8-26. Three studies performed follow-ups. H/GI reduced pain compared to controls at final treatment (SMD -1.17 [95% CI -2.21, -0.13]; p = 0.03. H/GI did not reduce limitations of HRQOL at final treatment (SMD -0.90 [95% CI -2.55, 0.76]; p = 0.29 compared to controls. Effect sizes on fatigue, sleep and depressed mood at final treatment and follow-up and on pain and HRQOL at follow-up were not calculated because of limited data available. The significant effect on pain at final treatment was associated with low methodological and low treatment quality. Conclusion Further studies with better treatment quality and adequate methodological quality assessing all key domains of FMS are necessary to clarify the efficacy of H/GI in FMS.

    2014-08-01

    The objective of this systematic review was to estimate the efficacy of protraction facemask on the correction of Class III malocclusion in the short term. A systematic review of articles was performed using different electronic databases (PubMed, Ovid, Cochrane Central Register of Controlled Trials, Web of Science, LILACS, and Google Scholar). Search terms comprised 'orthopedic treatment' and 'Class III malocclusion'. The selection criteria were set in order to include in this review only randomized clinical trials (RCTs) performed treating with facemask Class III growing patients. Studies' selection, data extraction, and risk of bias's assessment were executed independently by two authors using pre-defined data forms. All pooled analyses of data were based on random effects models. A pre-specified subgroup analysis was planned to evaluate the effect of preliminary rapid palatal expansion on facemask efficacy. Three RCTs met our inclusion criteria. In total, data from 155 patients (92 treated and 63 controls) were collected. The treated group showed the following significant changes: ANB° +3.66° [95%CI (2.58, 4.74)]; SNA° +2.10 [95%CI (1.14, 3.06)]; SNB° -1.54 [95%CI (-2.13, -0.95)]; SN-palatal plane -0.82° [95%CI (-1.62, -0.02)]; and SN-mandibular plane +1.51 [95%CI (0.61, 2.41)]. Heterogeneity varied from low to moderate (mean I(2) value: 41.4 ± 20.8). Facemask is effective correcting Class III malocclusion in the short term. The skeletal modifications induced by facemask are forward displacement of maxilla, backward displacement of mandible, clockwise rotation of the mandibular plane, and counterclockwise rotation of the maxillary plane.

    Full Text Available Abstract Background Attention-deficit/hyperactivity disorder (ADHD is a common neurobehavioral psychiatric disorder that afflicts children, with a reported prevalence of 2.4% to 19.8% worldwide. Stimulants (methylphenidate [MPH] and amphetamine are considered first-line ADHD pharmacotherapy. MPH is a catecholamine reuptake inhibitor, whereas amphetamines have additional presynaptic activity. Although MPH and amphetamine can effectively manage ADHD symptoms in most pediatric patients, many still fail to respond optimally to either. After administration, the prodrug stimulant lisdexamfetamine dimesylate (LDX is converted to l-lysine and therapeutically active d-amphetamine in the blood. The objective of this study was to evaluate the clinical efficacy of LDX in children with ADHD who remained symptomatic (ie, nonremitters; ADHD Rating Scale IV [ADHD-RS-IV] total score > 18 on MPH therapy prior to enrollment in a 4-week placebo-controlled LDX trial, compared with the overall population. Methods In this post hoc analysis of data from a multicenter, randomized, double-blind, forced-dose titration study, we evaluated the clinical efficacy of LDX in children aged 6-12 years with and without prior MPH treatment at screening. ADHD symptoms were assessed using the ADHD-RS-IV scale, Conners' Parent Rating Scale-Revised short form (CPRS-R, and Clinical Global Impressions-Improvement scale, at screening, baseline, and endpoint. ADHD-RS-IV total and CPRS-R ADHD Index scores were summarized as mean (SD. Clinical response for the subgroup analysis was defined as a ≥ 30% reduction from baseline in ADHD-RS-IV score and a CGI-I score of 1 or 2. Dunnett test was used to compare change from baseline in all groups. Number needed to treat to achieve one clinical responder or one symptomatic remitter was calculated as the reciprocal of the difference in their proportions on active treatment and placebo at endpoint. Results Of 290 randomized participants enrolled, 28

This meta-analysis assessed the efficacy and safety of different doses of vortioxetine for generalized anxiety disorder of adults.Methods: PubMed, Cochrane Library, PsycINFO, and Clinical Trials databases were searched from 2000 through 2015. The abstracts of the annual meetings of the American Psychiatric Association and previous reviews were searched to identify additional studies. The search was limited to individual randomized controlled trials (RCTs, and there was no language restriction. Four RCTs met the selection criteria. These studies included 1,843 adult patients. Results were expressed as odds ratios (ORs and 95% confidence intervals (CIs. The data were pooled with a random-effects or fixed-effects model.Results: The results showed that multiple doses (2.5, 5, and 10 mg/d of vortioxetine did not significantly improve the generalized anxiety disorder symptoms compared to placebo (OR=1.16, 95% CI=0.84–1.60, Z=0.89, P=0.38; OR=1.41, 95% CI=0.82–2.41, Z=1.25, P=0.21; OR=1.05, 95% CI=0.76–1.46, Z=0.32, P=0.75, respectively. We measured the efficacy of 2.5 mg/d vortioxetine compared to 10 mg/d, and no significant differences were observed. The common adverse effects included nausea and headache. With increased dose, nausea was found to be more frequent in the vortioxetine (5 and 10 mg/d group (OR=2.99, 95% CI=1.31–6.84, Z=2.60, P=0.009; OR=2.80, 95% CI=1.85–4.25, Z=4.85, P<0.00001, respectively, but no significant differences were observed for headache.Conclusion: The results showed no significant improvement in the treatment of generalized anxiety disorder for vortioxetine compared to placebo

    2017-03-01

    Group-based social skills interventions (GSSIs) are widely used for treating social competence among youth with autism spectrum disorder (ASD), but their efficacy is unclear. Previous meta-analysis of the literature on well-designed trials of GSSIs is limited in size and scope, collapsing across highly heterogeneous sources (parents; youths; teachers; observers; behavioral tasks). The current meta-analysis of randomized control trials (RCTs) was conducted to ascertain overall effectiveness of GSSIs and differences by reporting sources. Nineteen RCTs met inclusion criteria. Results show that overall positive aggregate effects were medium (g=0.51, p<0.001). Effects were large for self-report (g=0.92, p<0.001), medium for task-based measures (g=0.58, p<0.001), small for parent- and observer-report (g=0.47 and 0.40, respectively, p<0.001), and nonsignificant for teacher-report (p=0.11). Moderation analyses of self-report revealed the effect was wholly attributable to youth reporting that they learned about skilled social behaviors (social knowledge; g=1.15, p<0.01), but not that they enacted them (social performance; g=0.28, p=0.31). Social skills interventions presently appear modestly effective for youth with ASD, but may not generalize to school settings or self-reported social behavior.

    The treatment of moyamoya disease (MMD) is controversial and often depends on the doctor's experience. In addition, the choice of surgical procedure to treat MMD can differ in many ways. In this study, we performed a meta-analysis to determine whether surgical treatment of MMD is superior to conservative treatment and to provide evidence for the selection of an appropriate surgical treatment.The human case-control studies regarding the association of MMD treatment were systematically identified through online databases (PubMed, Web of Science, Elsevier Science Direct, and Springer Link). Inclusion and exclusion criteria were defined for the eligible studies. The fixed-effects model was performed when homogeneity was indicated. Alternatively, the random-effects model was utilized.This meta-analysis included 16 studies. Surgical treatment significantly reduced the risk of stroke (odds ratio (OR) of 0.17, 95% confidence interval (CI), 0.12-0.26, P direct bypass surgery, indirect bypass surgery had a lower efficacy on secondary stroke risk reduction (OR of 1.79, 95% CI, 1.14-2.82, P = 0.01), while no significant difference was detected for perioperative complications.Surgery is an effective treatment for symptomatic MMD patients, and direct bypass surgery may bring more benefits for these patients.

    Extranodal natural killer/T-cell lymphoma (ENKTL) is an aggressive neoplasm with a poor outcome. Novel L-asparaginase-based treatment regimens, such as GELOX (gemcitabine, oxaliplatin, and L-asparaginase) and P-gemox (gemcitabine, oxaliplatin, and pegaspargase), have shown promising results against stage IE/IIE ENKTL. To define the general applicability of P-gemox, in a retrospective analysis we examined the efficacy and safety of P-gemox in a cohort of 117 patients with newly diagnosed or relapsed/refractory ENKTL. Treatment included 2 to 8 cycles of P-gemox: intravenous gemcitabine (1250 mg/m2) and oxaliplatin (85 mg/m2) and intramuscular pegaspargase (2500 IU/m2) on day 1 and repeated every 2 weeks, or intravenous gemcitabine (1000 mg/m2) on days 1 and 8 and intravenous oxaliplatin (130 mg/m2) and intramuscular pegaspargase (2500 IU/m2) on day 1 and repeated every 3 weeks. Upon completion of treatment, the overall response rate was 88.8%, and responses were similar for newly diagnosed and relapsed/refractory patients. After a median follow-up of 17 months, the 3-year overall and progression-free survival rates were 72.7% and 57.8%, respectively. Multivariate analysis showed that CR after treatment was the most significant factor affecting survival. P-gemox thus appears to be an effective and well-tolerated treatment for patients with ENKTL.

    We perform this meta-analysis to compare the efficacy and safety of cryoablation versus radiofrequency ablation for patients with cavotricuspid valve isthmus dependent atrial flutter. By searching EMBASE, MEDLINE, PubMed and Cochrane electronic databases from March 1986 to September 2014, 7 randomized clinical trials were included. Acute (risk ratio[RR]: 0.93; P = 0.14) and long-term (RR: 0.94; P = 0.08) success rate were slightly lower in cryoablation group than in radiofrequency ablation group, but the difference was not statistically significant. Additionally, the fluoroscopy time was nonsignificantly reduced (weighted mean difference[WMD]: -2.83 P = 0.29), whereas procedure time was significantly longer (WMD: 25.95; P = 0.01) in cryoablation group compared with radiofrequency ablation group. Furthermore, Pain perception during the catheter ablation was substantially less in cryoabaltion group than in radiofrequency ablation group (standardized mean difference[SMD]: -2.36 P < 0.00001). Thus, our meta-analysis demonstrated that cryoablation and radiofrequency ablation produce comparable acute and long-term success rate for patients with cavotricuspid valve isthmus dependent atrial flutter. Meanwhile, cryoablation ablation tends to reduce the fluoroscopy time and significantly reduce pain perception in cost of significantly prolonged procedure time.

This meta-analysis of randomized controlled trials (RCTs was made in accordance with the instructions “Preferred reporting items for systematic reviews and meta-analyses (PRISMA”.Results. The meta-analysis included 5 RCTs. NOACs were as effective as vitamin K antagonists (VKAs in preventing recurrent symptomatic VTE (RR=0.93; 95% CI 0.77-1.12; p=0.44. The incidence of recurrent thrombosis (RR=0.82; 95% CI 0.63-1.08; p=0.16 and deep vein thrombosis ± fatal or nonfatal pulmonary embolism (RR=1.06; 95% CI 0.81-1.40; p=0.66 was comparable in the groups of comparison. Meta-analysis of the safety of the NOACs suggested significant reduction of risk of major bleeding as compared with standard therapy (RR=0.54; 95% CI 0.42-0.69; р<0.00001. The incidence of all types of bleeding was significantly lower with NOACs (RR=0.70; 95% CI 0.51-0.95; p=0.02. All-cause mortality rate was comparable between the groups (RR=0.93; 95% CI 0.76-1.13; p=0.46.Conclusions. NOACs are as effective as the standard therapy, at that they are much safer in VTE treatment.

  9. [A new LH-RH agonist for treatment of prostate cancer, 3-month controlled-release formulation of goserelin acetate (Zoladex LA 10.8 mg depot)--outline of pre-clinical and clinical studies].

    Tsukagoshi, Shigeru

    2002-09-01

    Goserelin acetate is a LH-RH agonist developed by AstraZeneca (formerly ICI, UK), and has been used clinically for the treatment of prostate cancer as a 4-week controlled-release formulation (Zoladex 3.6 mg depot). Recently, a new drug (Zoladex LA 10.8 mg depot) with 3-month controlled-release formulation was developed and became commercially available in Japan. In the randomized comparative phase III studies carried out with global bases, single administration of the new drug yielded almost equivalent anti-testosterone effect and the same serum level of the previous 3.6 mg depot formulation in 3-times continuous administration. In these studies, adverse drug reactions, which were mainly due to pharmacological effects of the new drug and minimal, were found in 52.6% (41/78) compared with 54.8% (46/84) with the previous 3.6 mg depot formulation. In the phase III studies, there were no significant differences in average serum testosterone levels between the two formulations at 12 and 13 weeks after administration. In the Japanese late phase II study with untreated patients, castration effect was observed in all 20 cases entered in the trial. In 20 cases in which treatment was switched from 3.6 mg depot to the new formulation, there were no significant changes in serum testosterone levels at castration level of the untreated patients, 90% (18/20) responded to the treatment, and normalization of PSA level was found in 75.0% (15/20). The adverse drug reactions were mainly increased triglyceride level and hot flushes. In the retrospective evaluation of untreated patients in this trial and the post-marketing clinical trial data for 3.6 mg depot, it was concluded that the new drug had almost the same efficacy and safety profile as 3.6 mg depot in Japanese people. These results indicate that Zoladex LA 10.8 mg depot has the same efficacy and safety as 3.6 mg depot with administration every three months, the burden of injection of LH-RH agonist can be reduced.

    with an improvement in forced expiratory volume in 1 second (FEV1 after 3-month treatment with ICS/long-acting beta2-agonist (LABA in stable COPD patients. Patients and methods: Blood eosinophils and plasma periostin levels were measured in 130 stable COPD subjects selected from the Korean Obstructive Lung Disease cohort. Subjects began a 3-month ICS/LABA treatment after washout period. Results: High blood eosinophils (>260/µL, adjusted odds ratio =3.52, P=0.009 and high plasma periostin (>23 ng/mL, adjusted odds ratio =3.52, P=0.013 were significantly associated with FEV1 responders (>12% and 200 mL increase in FEV1 from baseline after treatment. Moreover, the addition of high blood eosinophils to age, baseline positive bronchodilator response, and FEV1 <50% of the predicted value significantly increased the area under the curve for prediction of FEV1 responders (from 0.700 to 0.771; P=0.045. Conclusion: High blood eosinophils and high plasma periostin were associated with improved lung function after 3-month ICS/LABA treatment. In particular, high blood eosinophils, in combination with age and baseline lung function parameters, might be a possible biomarker for identification of COPD patients with favorable FEV1 improvement in response to ICS/LABA treatment.

  11. A meta-analysis of the efficacy of music therapy for premature infants.

    Standley, Jayne M

    2002-04-01

    This meta-analysis on music research with premature infants in neonatal intensive care units (NICU) showed an overall large, significant, consistent effect size of almost a standard deviation (d =.83) (Cohen, 1998). Effects were not mediated by infants' gestational age at the time of study, birthweight, or type of music delivery nor by physiologic, behavioral, or developmental measures of benefit. The homogeneity of findings suggests that music has statistically significant and clinically important benefits for premature infants in the NICU. The unique acoustic properties that differentiate music from all other sounds are discussed and clinical implications for research-based music therapy procedures cited.

  12. Efficacy of citicoline as an acute stroke treatment.

    Clark, Wayne M

    2009-04-01

    Citicoline (cytidine-5'-diphosphocholine or CDP-choline) is a precursor essential for the synthesis of phosphatidylcholine, one of the cell membrane components that is degraded during cerebral ischemia to free fatty acids and free radicals. Animal studies suggest that citicoline may protect cell membranes by accelerating resynthesis of phospholipids and suppressing the release of free fatty acids, stabilizing cell membranes, and reducing free radical generation. Numerous experimental stroke studies with citicoline have shown improved outcome and reduced infarct size in both ischemic and hemorrhagic stroke models. Citicoline has been studied worldwide in both ischemic and hemorrhagic clinical stroke with excellent safety and possibly efficacy found in several trials. A meta-analysis of four randomized US clinical citicoline trials concluded that treatment with oral citicoline within the first 24 h after a moderate to severe stroke is safe and increases the probability of complete recovery at 3 months. Citicoline clinical efficacy trials are now continuing outside of the US in both ischemic and hemorrhagic stroke. A citicoline supplement is now available from several sources on the internet.

    Full Text Available BACKGROUND: The fixed dose antimalarial combination of dihydroartemisinin-piperaquine (DP is a promising new artemisinin-based combination therapy (ACT. We present an individual patient data analysis of efficacy and tolerability in acute uncomplicated falciparum malaria, from seven published randomized clinical trials conducted in Africa and South East Asia using a predefined in-vivo protocol. Comparator drugs were mefloquine-artesunate (MAS3 in Thailand, Myanmar, Laos and Cambodia; artemether-lumefantrine in Uganda; and amodiaquine+sulfadoxine-pyrimethamine and artesunate+amodiaquine in Rwanda. METHODS AND FINDINGS: In total 3,547 patients were enrolled: 1,814 patients (32% children under five years received DP and 1,733 received a comparator antimalarial at 12 different sites and were followed for 28-63 days. There was no significant heterogeneity between trials. DP was well tolerated with 1.7% early vomiting. There were less adverse events with DP in children and adults compared to MAS3 except for diarrhea; ORs (95%CI 2.74 (2.13 to 3.51 and 3.11 (2.31 to 4.18, respectively. DP treatment resulted in a rapid clearance of fever and parasitaemia. The PCR genotype corrected efficacy at Day 28 of DP assessed by survival analysis was 98.7% (95%CI 97.6-99.8. DP was superior to the comparator drugs in protecting against both P.falciparum recurrence and recrudescence (P = 0.001, weighted by site. There was no difference between DP and MAS3 in treating P. vivax co-infections and in suppressing the first relapse (median interval to P. vivax recurrence: 6 weeks. Children under 5 y were at higher risk of recurrence for both infections. The proportion of patients developing gametocytaemia (P = 0.002, weighted by site and the subsequent gametocyte carriage rates were higher with DP (11/1000 person gametocyte week, PGW than MAS3 (6/1000 PGW, P = 0.001, weighted by site. CONCLUSIONS: DP proved a safe, well tolerated, and highly effective treatment of P

  14. Efficacy and safety of Tai Chi for Parkinson's disease: a systematic review and meta-analysis of randomized controlled trials.

    Xiaojia Ni

    Full Text Available In Parkinson's disease (PD, wearing off and side effects of long-term medication and complications pose challenges for neurologists. Although Tai Chi is beneficial for many illnesses, its efficacy for PD remains uncertain. The purpose of this review was to evaluate the efficacy and safety of Tai Chi for PD.Randomized controlled trials (RCTs of Tai Chi for PD were electronically searched by the end of December 2013 and identified by two independent reviewers. The tool from the Cochrane Handbook 5.1 was used to assess the risk of bias. A standard meta-analysis was performed using RevMan 5.2 software.Ten trials with PD of mild-to-moderate severity were included in the review, and nine trials (n = 409 were included in the meta-analysis. The risk of bias was generally high in the blinding of participants and personnel. Improvements in the Unified Parkinson's Disease Rating Scale Part III (mean difference (MD -4.34, 95% confidence interval (CI -6.67--2.01, Berg Balance Scale (MD: 4.25, 95% CI: 2.83-5.66, functional reach test (MD: 3.89, 95% CI: 1.73-6.04, Timed Up and Go test (MD: -0.75, 95% CI: -1.30--0.21, stride length (standardized MD: 0.56, 95% CI: 0.03-1.09, health-related quality of life (standardized MD: -1.10, 95% CI: -1.81--0.39 and reduction of falls were greater after interventions with Tai Chi plus medication. Satisfaction and safety were high. Intervention with Tai Chi alone was more effective for only a few balance and mobility outcomes.Tai Chi performed with medication resulted in promising gains in mobility and balance, and it was safe and popular among PD patients at an early stage of the disease. This provides a new evidence for PD management. More RCTs with larger sample size that carefully address blinding and prudently select outcomes are needed.

    2014-09-03

    The World Health Organization has stipulated a target: reduce the mortality rate caused by dengue disease by 50% until 2020. Most likely, this goal can be achieved by means of a dengue vaccine. Accordingly, the recombinant and tetravalent dengue vaccine (CYD-TDV), developed by the Sanofi Pasteur Group, is in an advanced stage of human testing. Although there are multiple randomized, placebo-controlled trials evaluating the CYD-TDV, individual results may have little power to identify differences between the populations studied. Thus, we conducted a meta-analysis to determine a more precise estimate of the overall parameters of safety, immunogenicity and efficacy of CYD-TDV. A data search was conducted in the PubMed, Medline, Cochrane Central Register of Controlled Trials and SciELO databases with defined selection criteria. We included for meta-analysis seven randomized and placebo-controlled studies that included 6678 patients randomized to receive the CYD-TDV (4586) or placebo (2092). Regarding vaccine safety, it was found that there was no significant difference between treated and placebo groups, as only approximately 5.5% of patients were withdrawn from the study. Regarding immunogenicity, the levels of neutralizing antibodies were measured by weighted mean differences (WMD), which were always higher in the vaccinated group (WMD/DENV1=59.7, 95% confidence interval [CI] 57-61; WMD/DENV2=99, 95% CI 95-102; WMD/DENV3=138, 95% CI 133-142; WMD/DENV4=123, 95% CI 119-126). The clinical efficacy of the vaccine was 59% (95% CI 15-80; RR=0.41, 95% CI 0.2-0.85, I(2)=30.9%). In conclusion, safety and a balanced immune response to the CYD-TDV were found. However, to fully establish the clinical effectiveness and robustness of immunogenicity, it is necessary to perform further studies to assess the long-term effects of the vaccine.

  2. Do equivalent doses of escitalopram and citalopram have similar efficacy? A pooled analysis of two positive placebo-controlled studies in major depressive disorder.

    Lepola, Ulla; Wade, Alan; Andersen, Henning Friis

    2004-05-01

    Escitalopram is the S-enantiomer of citalopram. In this study, we compared the efficacy of equivalent dosages of escitalopram and citalopram in the treatment of moderate to severe major depressive disorder (MDD), based on data from two, pooled, randomized, double-blind, placebo-controlled studies of escitalopram in which citalopram was the active reference. The primary efficacy parameter was the mean change from baseline in the Montgomery Asberg Depression Rating Scale (MADRS) total score. Significant differences in favour of escitalopram were observed for the MADRS [PEscitalopram separated from placebo at week 1 on the primary efficacy parameter, whereas citalopram first separated from placebo at week 6. An analysis of time to response showed that escitalopram-treated patients responded significantly faster to treatment than citalopram-treated patients (Pescitalopram than to citalopram (Pescitalopram-treated patients had a significant reduction in HAMD-17 total score at week 8 compared to citalopram-treated patients (P or = 30), escitalopram-treated patients showed greater improvement than citalopram-treated patients (PEscitalopram showed consistently superior efficacy compared to citalopram in the treatment of moderate to severe MDD on all efficacy parameters, and was similarly well tolerated.

  3. Molluscicidal efficacies of different formulations of niclosamide: result of meta-analysis of Chinese literature

    Full Text Available Abstract The control efforts on Oncomelania hupensis, the intermediate snail host of Schistosoma japonicum, cannot be easily excluded from the integrated approach of schistosomiasis control in China. Application of chemical compounds, molluscicides, in snail habitats is a common method for snail control in addition to environmental modification. We conducted a systematic review and meta-analysis to assess the molluscicidal effects of the currently recommended 50% niclosamide ethanolamine salt wettable powder and a new 4% niclosamide ethanolamine salt powder developed by Chinese researchers. Literature was searched from three Chinese databases, i.e. Chinese Biomedical Database, VIP Database and Wanfang Database, on field mollusciciding trials of niclosamide in China (from January 1, 1990 to April 1, 2010. Molluscicidal effects on reduction of snail population of the 50% or 4% niclosamide formulations in field trial were evaluated 3 days, 7 days or 15 days post-application. Out of 90 publications, 20 papers were eventually selected for analysis. Publication bias and heterogeneity tests indicated that no publication bias existed but heterogeneity between studies was present. Meta-analysis in a random effect model showed that the snail mortality of 3, 7 and 15 days after spraying the 50% niclosamide ethanolamine salt wettable powder were 77% [95%CI: 0.68-0.86], 83% [95%CI: 0.77-0.89], and 88% [95%CI: 0.82-0.92], respectively. For the 4% niclosamide ethanolamine salt powder, the snail mortality after 3, 7 and 15 days were 81% [95%CI: 0.65-0.93], 90% [95%CI: 0.83-0.95] and 94% [95%CI: 0.91-0.97], respectively. Both are good enough to be used as molluscicides integrated with a schistosomiasis control programme. The 4% niclosamide ethanolamine salt powder can be applied in the field without water supply as the surrogate of the current widely used 50% niclosamide ethanolamine salt wettable powder. However, to consolidate the schistosomiasis control

With the treatment of UTI, CD4+T cells raised 5.13%, mean = 5.13, 95% CI [2.75, 7.50] (p<0.0001; there was no significant change in CD8+T cells, mean = −0.74 [−2.93, 1.45] (p=0.51. Conclusion. According to this meta-analysis, with the treatment of UTI, the short-term survival rate of septic patients was increased and the illness severity was alleviated. ICU stay and mechanical ventilation time were effectively shortened. The beneficial effect of UTI might be due to the potential immunomodulatory effects of these two drugs.

    Six Sigma is a strategy for achieving process improvement and operational excellence within an organization. Decisions on critical parameter selection in analysis phase are always very crucial; it plays a primary role in successful execution of Six Sigma project and for productivity improvement in manufacturing environment and involves the imprecise, vague and uncertain information. Using a case study approach; the paper demonstrates a tactical approach for selection of critical factors of machine breakdown in center less grinding (CLG) section at an automotive industry using fuzzy logic based multi attribute decision making approach. In this context, we have considered six crucial attributes for selection of critical factors for breakdown. Mean time between failure is found to be the pivotal selection criterion in CLG section. Having calculated the weights pertinent to criteria through two methods (fuzzy VIKOR and fuzzy TOPSIS) critical factors for breakdown are prioritized. Our results are in strong agreement with the perceptions of production and maintenance department of the company.

    Full Text Available Scientific background: Appendicitis is an inflammation of the appendix of the blind intestine. Appendicitis remains the most frequent cause for an acute abdomen. Both interventions, the open surgical (through opening of the abdominal cavity as well as the laparoscopic approach (via insertion of an optic system and instruments into the abdominal cavity through three small incisions, are used for the excision of the inflamed appendix (appendectomy. Research questions: The performed evaluation addresses questions on the medical effectiveness of the use of laparoscopic appendectomy in comparison with the classical open appendix excision as well as on its cost-effectiveness based on the German health system. Methods: A literature search was conducted in October 2005 in the most important medical electronic databases. The medical analysis was performed on the basis of the most up to date systematic review (basic review of randomized controlled studies (RCT, newly published RCT and on our own quantitative information synthesis of all studies as well as of selected methodologically high-value RCT. In the health economic analysis, relevant publications were evaluated and cost differences of both interventions were calculated. Results: One systematic review and 56 primary studies were included in the medical evaluation, 24 of these studies were included in the conducted subanalysis on the basis of methodologically high-value studies. In total, a relation of three avoided wound infections per one additional intraabdominal abscess has to be expected by the use of laparoscopic appendectomy in com-parison with the open operation. Diagnostic laparoscopy reduces the rate of unclear diagnoses within the scope of planned appendectomy in fertile women. By routine, leaving the macroscopically bland appendix in situ, the rate of negative appendectomy is reduced significantly and profound. The results speak for a small advantage of the laparoscopic appendec-tomy with

    Full Text Available Since ancient time, an increased interest had been witnessed in the use of an alternative herbal medicine for managing and the treatment of fungal disease worldwide. This may be connected to the cost and relative toxicities of the available fungal drugs. Since ancient time, it has been a known tradition practised in the northern part of Nigeria that parents and teachers use the white latex of Calotropis procera (Tumfafiya to treat Tinea capitis (Makero in children attending the local religious school in the area. This study was conducted in 2009 to designed to ascertain the above claim scientifically. Latex extract of Calotropis procera was screened for their antifungal and phytochemical properties. Agar incorporation method against species of dermatophytes: Trichophyton sp., Microsporum sp. and Epidermophyton sp. shows that the latex inhibits the in vitro growth of these three filamentous fungi to varying extents. Statistical analysis of the results shows that Trichophyton sp. is the most susceptible and thus highly inhabited by the latex extract followed by the Microsporum Sp. and Epidermopyton sp. was least inhibited. Undiluted latex (100% of C. procera gave the highest inhibitory impacts on the dermatophytes and corresponding lowest least (20% concentration. The phytochemical analysis of the latex extract indicates the presence alkaloids, saponin, tannins, steroids, flavonoids, anthraquinone and triterpenoids. The findings of this study confirmed the perceived usefulness of the latex in the treatment of Tinea capitis (ringworm practiced in the society and therefore, its use in the treatment of dermatomycotic infection is encouraged.

    Abstract Background: A variety of targeted drug therapies in clinical trials have been proven to be effective for the treatment of hepatocellular carcinoma (HCC). Our study aims to compare the short-term and long-term efficacies of different targeted drugs in advanced hepatocellular carcinoma (AHCC) treatment using a network meta-analysis approach. Methods: PubMed, Embase, Ovid, EBSCO, and Cochrane central register of controlled trials were searched for randomized controlled trials (RCTs) of different targeted therapies implemented to patients with AHCC. And the retrieval resulted in 7 targeted drugs, namely, sorafenib, ramucirumab, everolimus, brivanib, tivantinib, sunitinib, and sorafenib+erlotinib. Direct and indirect evidence were combined to evaluate stable disease (SD), progressive disease (PD), complete response (CR), partial response (PR), disease control rate (DCR), overall response ratio (ORR), overall survival (OS), and surface under the cumulative ranking curve (SUCRA) of patients with AHCC. Results: A total of 11 RCTs were incorporated into our analysis, including 6594 patients with AHCC, among which 1619 patients received placebo treatment and 4975 cases had targeted therapies. The results revealed that in comparison with placebo, sorafenib, and ramucirumab displayed better short-term efficacy in terms of PR and ORR, and brivanib was better in ORR. Regarding long-term efficacy, sorafenib and sorafenib+erlotinib treatments exhibited longer OS. The data of cluster analysis showed that ramucirumab or sorafenib+erlotinib presented relatively better short-term efficacy for the treatment of AHCC. Conclusion: This network meta-analysis shows that ramucirumab and sorafenib+erlotinib may be the better targeted drugs for AHCC patients, and sorafenib+erlotinib achieved a better long-term efficacy.

  12. Effect of colostrum redox balance on the oxidative status of calves during the first 3 months of life and the relationship with passive immune acquisition.

    Abuelo, Angel; Pérez-Santos, María; Hernández, Joaquín; Castillo, Cristina

    2014-02-01

    New-born calves depend upon colostrum intake for the acquisition of immunoglobulins (Ig) and other beneficial substances. However, colostrum is also a source of reactive oxygen species (ROS). Intrinsic production of ROS also increases after birth, so the combination of colostral and intrinsic ROS could overwhelm the antioxidant capacity of the calf leading to oxidative stress (OS), a condition that has been shown to play a key role in the initiation and development of several pathological conditions. The aim of this observational study was to assess the effects of the redox balance of colostrum on the oxidative status of calves and on passive immune transfer. Serum samples were taken from 20 calves on their day of birth, every week during their first month of life and at 2 and 3 months of age, and the concentrations of ROS and serum antioxidant capacity (SAC) assayed. The oxidative/anti-oxidative profile and IgG content of the colostrum were also assessed. The redox balance of the colostrum had a significant effect on both calf oxidative status and on passive immune transfer (as measured by calf serum IgG concentration), which indicates that the oxidative/antioxidative profile of colostrum should be measured when colostrum quality is assessed. The highest risk of OS during the study period was found to be when the calves were fed artificial milk replacer; this suggests that calves should be supplemented with antioxidants during this period in order to minimize any harmful consequences of high ROS generation.

    Full Text Available The aim of the study was to determine the effect of regular participation in home-based exercise programme on cognitive functioning changes in institutionalised older adults. Two groups of participants were recruited for the study: experimental (n = 17 in mean age 76 ± 5.6 years, who participated in home-based exercise program and control (n = 14 in mean age 80 ± 4.2 years. The standardised Stroop Color-Word Test-Victoria version (VST was used to measure the level of cognitive functions. Group differences were analyzed with Mann-Whitney U-test for independent samples and for differences between pre-measurements and post-measurements on experimental and control group we used non-parametric Wilcoxon Signed - Rank Test. The level of significance was α < 0.05. Application of 3-months home-based exercise program significantly improved the cognitive functions only in one (Word condition; p<0.01 from three VST conditions in institutionalised older adults. That’s why we recommend longer participation in home-based exercise program, at least 6- months, with combination of various types of cognitive interventions, like concepts of cognitive training, cognitive rehabilitation, and cognitive stimulation to improve cognitive functioning in older adults living in old peoples’ homes.

  14. Dialectical behaviour therapy-informed skills training for deliberate self-harm: a controlled trial with 3-month follow-up data.

    Gibson, Jennifer

    2014-09-01

    Dialectical Behaviour Therapy (DBT) has been shown to be an effective treatment for deliberate self-harm (DSH) and emerging evidence suggests DBT skills training alone may be a useful adaptation of the treatment. DBT skills are presumed to reduce maladaptive efforts to regulate emotional distress, such as DSH, by teaching adaptive methods of emotion regulation. However, the impact of DBT skills training on DSH and emotion regulation remains unclear. This study examined the Living Through Distress (LTD) programme, a DBT-informed skills group provided in an inpatient setting. Eighty-two adults presenting with DSH or Borderline Personality Disorder (BPD) were offered places in LTD, in addition to their usual care. A further 21 clients on the waiting list for LTD were recruited as a treatment-as-usual (TAU) group. DSH, anxiety, depression, and emotion regulation were assessed at baseline and either post-intervention or 6 week follow-up. Greater reductions in the frequency of DSH and improvements in some aspects of emotion regulation were associated with completion of LTD, as compared with TAU. Improvements in DSH were maintained at 3 month follow-up. This suggests providing a brief intensive DBT-informed skills group may be a useful intervention for DSH.

    Primary hyperoxaluria (PH1) is a rare inborn autosomal recessive metabolic disorder due to the deficiency of hepatic alanine-glyoxylate-aminotransferase. This deficiency results in excessive synthesis and urinary excretion of oxalate, inducing renal stone formation and deposition of calcium oxalate in the kidney, bone, myocardium, and vessels (systemic oxalosis, SO) in the most severely affected individuals. We report renal and skeletal changes in a 3-month-old girl with PH1 and SO. Intense cortico-medullary hyperechogenicity and increased homogeneous radiopacity of normal-sized kidneys suggested the diagnosis of SO. Skeletal survey showed osteopenia and characteristic symmetrical metaphyseal transverse bands in long bones, progressively becoming more dense and migrating towards the diaphysis. Multiple pathological and slowly healing fractures of the limbs occurred at the dense band level. A radiopaque rim was then observed in flat bones, epiphyseal nuclei, and vertebral bodies. Inflammatory granulomatous reaction, induced by the presence of oxalate crystals in the marrow spaces, coexisted with progressively evident radiological signs of secondary hyperparathyroidism, with partially overlapping features. The patient was treated by peritoneal dialysis and hemodialysis until combined liver-kidney transplantation. There are no previous reports of infants treated with hemodialysis for more than 2 years.

    Teachers and students often suffer from the same disaster. The prevalence of PTSD in students has been given great attention. However, in acting as mentors to students and their families, teachers are more likely to have vicarious and indirect exposure via hearing stories of their aftermath and witnessing the consequences of traumatic events. There are limited data pertaining to the prevalence of PTSD and its risk factors among teachers. A total of 316 teachers from 21 primary and secondary schools in Baoxing County were administered a project-developed questionnaire which included the items regarding demographic characteristics, earthquake-related experiences, somatic discomforts, emotional reactions, support status, and everyday functioning 2 weeks after the Lushan earthquake, and they finished a 1-to-1 telephone interview for addressing the PTSD criteria of the Mini International Neuropsychiatric Interview (MINI) 3 months after the earthquake. The prevalence of PTSD was 24.4% among teachers. Somatic discomforts (odds ratio [OR] 1.89, 95% confidence interval [CI] 1.06-3.37) were positive risk factors of PTSD. Perceived social support (OR 0.30, 95% CI 0.14-0.62) and being able to calm down (OR 0.25, 95% CI 0.09-0.75) in teaching were negative risk factors. PTSD is commonly seen among teachers after an earthquake, and risk factors of PTSD were identified. These findings may help those providing psychological health programs to find the teachers who are at high risk of PTSD in schools after an earthquake in China.

    A low glycaemic index (LGI) diet during pregnancy complicated by gestational diabetes mellitus (GDM) may offer benefits to the mother and infant pair beyond those during pregnancy. We aimed to investigate the effect of an LGI diet during pregnancy complicated with GDM on early post-natal outcomes. Fifty-eight women (age: 23-41 years; mean ± SD pre-pregnancy body mass index: 24.5 ± 5.6 kg m(-2) ) who had GDM and followed either an LGI diet (n = 33) or a conventional high-fibre diet (HF; n = 25) during pregnancy had a 75-g oral glucose tolerance test and blood lipid tests at 3 months post-partum. Anthropometric assessments were conducted for 55 mother-infant pairs. The glycaemic index of the antenatal diets differed modestly (mean ± SD: 46.8 ± 5.4 vs. 52.4 ± 4.4; P diet during pregnancy complicated by GDM has outcomes similar to those of a conventional healthy diet. Adequately powered studies should explore the potential beneficial effects of LGI diet on risk factors for chronic disease.

    2010-12-01

    The effects of casein phosphopeptide amorphous calcium fluoride phosphate (CPP-ACFP) paste vs. control paste on the remineralization of white spot caries lesions and on plaque composition were tested in a double-blind prospective randomized clinical trial. Fifty-four orthodontic patients, with multiple white spot lesions observed upon the removal of fixed appliances, were followed up for 3 months. Subjects were included and randomly assigned to either CPP-ACFP paste or control paste, for use supplementary to their normal oral hygiene. Caries regression was assessed on quantitative light-induced fluorescence (QLF) images captured directly after debonding and 6 and 12 wk thereafter. The total counts and proportions of aciduric bacteria, Streptococcus mutans, and Lactobacillus spp. were measured in plaque samples obtained just before debonding, and 6 and 12 wk afterwards. A significant decrease in fluorescence loss was found with respect to baseline for both groups and no difference was found between groups. The size of the lesion area did not change significantly over time or between the groups. The percentages of aciduric bacteria and of S. mutans decreased from 47.4 to 38.1% and from 9.6 to 6.6%, respectively. No differences were found between groups. We observed no clinical advantage for use of the CPP-ACFP paste supplementary to normal oral hygiene over the time span of 12 wk.

    Full Text Available Introduction: prostatic cancer is the second more frequent cancer in Italy (after lung cancer and is the third cancer-related death cause. Age is the principal risk factor and, given the ageing process undergoing in the Italian population, it seems clear that the public sanitary expenditure to treat the disease is bound to increase, arising the need to perform pharmacoeconomic evaluations of the therapeutic strategies available. Methods: we performed a cost/utility analysis, through a Markov model, of several hormonal therapies in patients with advanced prostate cancer who underwent radical prostatectomy, from the biochemical recurrence to death. Nine androgen suppression therapies were considered: orchiectomy, two nonsteroidal antiandrogens (NSAA, four luteinizing hormone-releasing hormone (LHRH agonists, cyproterone acetate and the association of a NSAA and a LHRH (BAT. In the simulation the androgen suppression therapies were started at the PSA recurrence and never stopped until death. The model used the Italian NHS prospective and a time horizon corresponding to patient’s lifetime. Drug costs were calculated for each therapy, considering the less costly brand. Results: all the considered therapies produced a life expectancy (LE of about 12 life years (LYs with a small variability ranging from 12.3 LYs for BAT (the most effective to 11.37 LYs for NSAA-flutamide (the least effective. Quality adjusted life expectancy ranged from 9.98 QALYs for BAT to 9.28 QALYs for NSAA-flutamide. The average cost per patient presented a more enhanced variability, from 12,538 Euro for orchiectomy to 59,496 Euro for NSAA-bicalutamide. Among all the alternatives orchiectomy resulted the most cost/effective alternative with a cost/utility ratio of about 1,300 Euro/QALY. In the LHRH-agonists class leuprorelin was the most cost/effective with about 2,200 Euro/QALY. A one-way sensitivity analysis showed a substantial stability of the results. Conclusions: BAT

    Objective This study aimed to determine the ef icacy of chemotherapy and to identify potential chemo-therapy agents to treat advanced primary duodenal carcinoma (PDC). Methods Seventy-three patients with advanced PDC were included in the study. Response rate (RR), disease control rate (DCR), progression-free survival (PFS), overal survival (OS) and prognosis were com-pared among patients using the Cox proportional hazards model. Results The overal RR and DCR of 52 patients were 21.15% and 69.23%, respectively. The median PFS and OS times were 4.51 and 11.47 months, respectively. Pal iative chemotherapy improved the OS of patients with advanced PDC compared with patients who did not receive chemotherapy (14.28 months vs. 5.20 months, HR = 0.205, 95% CI: 0.077 to 0.547, P = 0.0016). Multivariate analysis indicated mucinous histology and liver metastasis as factors predictive of poor prognosis in patients with advanced PDC. Conclusion Pal iative chemotherapy may improve the OS of patients with advanced PDC. Mucinous histology and liver metastasis were the main prognostic factors in patients with advanced PDC.

    Swelling is the most common symptom of extremities lymphedema. Clinical evaluation and laboratory analysis were conducted after far infrared radiation (FIR) treatment on the main four components of lymphedema: fluid, fat, protein, and hyaluronan. Far infrared radiation is a kind of hyperthermia therapy with several and additional benefits as well as promoting microcirculation flow and improving collateral lymph circumfluence. Although FIR therapy has been applied for several years on thousands of lymphedema patients, there are still few studies that have reported the biological effects of FIR on lymphatic tissue. In this research, we investigate the effects of far infrared rays on the major components of lymphatic tissue. Then, we explore the effectiveness and safety of FIR as a promising treatment modality of lymphedema. A total of 32 patients affected by lymphedema in stage II and III were treated between January 2015 and January 2016 at our department. After therapy, a significant decrease of limb circumference measurements was noted and improving of quality of life was registered. Laboratory examination showed the treatment can also decrease the deposition of fluid, fat, hyaluronan, and protein, improving the swelling condition. We believe FIR treatment could be considered as both an alternative monotherapy and a useful adjunctive to the conservative or surgical lymphedema procedures. Furthermore, the real and significant biological effects of FIR represent possible future applications in wide range of the medical field.

    Comparative analysis of the efficacy of a playful-narrative program to teach mathematics at pre-school level. In this paper, the effectiveness of a programme comprising several components that are meant to consolidate mathematical concepts and abilities at the pre-school level is analyzed. The instructional methodology of this programme is compared to other methodologies. One-hundred 5-6 year-old children made up the sample that was distributed in the following conditions: (1) traditional methodology; (2) methodology with perceptual and manipulative components, and (3) methodology with language and playful components. Mathematical competence was assessed with the Mathematical Criterial Pre-school Test and the subtest of quantitative-numeric concepts of BADyG. Participants were evaluated before and after the academic course during which they followed one of these methodologies. The results show that the programme with language and playful components is more effective than the traditional methodology (p<.000) and also more effective than the perceptual and manipulative methodology (p<.000). Implications of the results for instructional practices are analyzed.

    To evaluate the evidence for the use of probiotics in the prevention of acute diarrhoea, we did a meta-analysis of the available data from 34 masked, randomised, placebo-controlled trials. Only one trial was community based and carried out in a developing country. Most of the remaining 33 studies were carried out in a developed country in a health-care setting. Evaluating the evidence by types of acute diarrhoea suggests that probiotics significantly reduced antibiotic-associated diarrhoea by 52% (95% CI 35-65%), reduced the risk of travellers' diarrhoea by 8% (-6 to 21%), and that of acute diarrhoea of diverse causes by 34% (8-53%). Probiotics reduced the associated risk of acute diarrhoea among children by 57% (35-71%), and by 26% (7-49%) among adults. The protective effect did not vary significantly among the probiotic strains Saccharomyces boulardii, Lactobacillus rhamnosus GG, Lactobacillus acidophilus, Lactobacillus bulgaricus, and other strains used alone or in combinations of two or more strains. Although there is some suggestion that probiotics may be efficacious in preventing acute diarrhoea, there is a lack of data from community-based trials and from developing countries evaluating the effect on acute diarrhoea unrelated to antibiotic usage. The effect on acute diarrhoea is dependent on the age of the host and genera of strain used.

    The effectiveness of working memory (WM) training programmes is still a subject of debate. Previous reviews were heterogeneous with regard to participant characteristics of the studies included. To examine whether these programmes are of added value for children with learning disabilities (LDs), a systematic meta-analytic review was undertaken focusing specifically on LDs. Thirteen randomised controlled studies were included, with a total of 307 participants (age range = 5.5-17, Mean age across studies = 10.61, SD = 1.77). Potential moderator variables were examined, i.e., age, type of LD, training programme, training dose, design type, and type of control group. The meta-analysis indicated reliable short-term improvements in verbal WM, visuo-spatial WM, and word decoding in children with LDs after training (effect sizes ranged between 0.36 and 0.63), when compared to the untrained control group. These improvements sustained over time for up to eight months. Furthermore, children > 10 years seemed to benefit more in terms of verbal WM than younger children, both immediately after training as well as in the long-term. Other moderator variables did not have an effect on treatment efficacy.

In the article, the last name of author Emily Teding van Berkhout was incorrectly set in the running head as van Berkhout. It should be Teding van Berkhout. All versions of this article have been corrected.] High levels of empathy are associated with healthy relationships and prosocial behavior; in health professionals, high levels of empathy are associated with better therapeutic outcomes. To determine whether empathy can be taught, researchers have evaluated empathy training programs. After excluding 1 outlier study that showed a very large effect with few participants, the meta-analysis included 18 randomized controlled trials of empathy training with a total of 1,018 participants. The findings suggest that empathy training programs are effective overall, with a medium effect (g = 0.63), adjusted to 0.51 after trim-and-fill evaluation for estimated publication bias. Moderator analyses indicated that 4 factors were statistically significantly associated with higher effect sizes: (a) training health professionals and university students rather than other types of individuals, (b) compensating trainees for their participation, (c) using empathy measures that focus exclusively on assessing understanding the emotions of others, feeling those emotions, or commenting accurately on the emotions, and (d) using objective measures rather than self-report measures. Number of hours of training and time between preintervention assessment and postintervention assessment were not statistically significantly associated with effect size, with 6 months the longest time period for assessment. The findings indicate that (a) empathy training tends to be effective and (b) experimental research is warranted on the impact of different types of trainees, training conditions, and types of assessment.

    Full Text Available Hai Wang, Li Bo Man, Guang Lin Huang, Gui Zhong Li, Jian Wei WangDepartment of Urology, Beijing Jishuitan Hospital, Beijing, People’s Republic of China Objective: The aim of this study was to systematically compare the therapeutic effect and safety of tamsulosin with nifedipine in medical expulsive therapy for distal ureteral calculi.Methods: Databases, including PubMed, EMBASE, the Cochrane Library, and Clinical Trial Register Centers, were comprehensively searched. Relevant randomized controlled trials (RCTs were selected, and quality assessment was performed according to the Cochrane Handbook. RevMan software was used to analyze the outcome measures, which consisted of expulsion rate, expulsion time, and complications.Results: Twelve RCTs consisting of 4,961 patients were included (tamsulosin group, 2,489 cases; nifedipine group, 2,472 cases. Compared with nifedipine, tamsulosin significantly increased the expulsion rate (risk ratio =1.29, 95% CI [1.25, 1.33], P<0.0001 and reduced the expulsion time (standard mean difference =-0.39, 95% CI [−0.72, −0.05], P=0.02. Regarding safety, tamsulosin was associated with fewer complications than nifedipine (risk ratio =0.45, 95% CI [0.28, 0.72], P=0.0008, and further subgroup analysis showed that tamsulosin was associated with a lower risk of both mild and moderate-to-severe complications.Conclusion: On the bias of current evidence, tamsulosin showed an overall superiority to nifedipine for distal ureteral calculi <10 mm in aspects of expulsion rate, expulsion time, and safety. Tamsulosin was supposed to be the first drug to be recommended to patients willing to receive medical expulsive therapy.Keywords: tamsulosin, nifedipine, medical expulsive therapy, MET, lower urinary calculi

  7. The moderating effect of self-efficacy on normal-weight, overweight, and obese children's math achievement: a longitudinal analysis.

    Kranjac, Ashley Wendell

    2015-03-01

    Increased body weight is associated with decreased cognitive function in school-aged children. The role of self-efficacy in shaping the connection between children's educational achievement and obesity-related comorbidities has not been examined to date. Evidence of the predictive ability of self-efficacy in children is demonstrated in cognitive tasks, including math achievement scores. This study examined the relationship between self-efficacy and math achievement in normal weight, overweight, and obese children. I hypothesized that overweight and obese children with higher self-efficacy will be less affected in math achievement than otherwise comparable children with lower self-efficacy. I tested this prediction with multilevel growth modeling techniques using the ECLS-K 1998-1999 survey data, a nationally representative sample of children. Increased self-efficacy moderates the link between body weight and children's math achievement by buffering the risks that increased weight status poses to children's cognitive function. My findings indicate that self-efficacy moderates math outcomes in overweight, but not obese, children.

    Jung Soo Kim

    Full Text Available Two once-daily inhaled bronchodilators, indacaterol and tiotropium, are widely used as first-line therapy in stable COPD patients. This study was performed to compare the clinical efficacy and safety between indacaterol and tiotropium in patients with moderate-to-severe COPD. MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials were searched to identify all published randomized controlled trials (RCTs. The primary outcome was trough forced expiratory volume in 1 second (FEV1 at week 12. Four RCTs were eligible for inclusion (three RCTs with moderate-to-severe COPD patients and one RCT with only severe COPD patients. Trough FEV₁ at weeks 12 and 26 were not significantly different between indacaterol and tiotropium by the standardized mean difference with 0.014 (95% CI, -0.036, 0.063, I²= 23.5% and with 0.037 (95% CI, -0.059 to 0.133, I²= 0% along with differences in means of 0.003L and 0.014L, respectively. Indacaterol and tiotropium also showed similar St. George's Respiratory Questionnaire (SGRQ total scores and percentages of patients with SGRQ improvement (≥ 4 units at week 26. The incidences of nasopharyngitis, serious cardiovascular events, and serious adverse events were not different between indacaterol and tiotropium, while those of cough (OR = 1.68, P < 0.001, and RR = 1.63 and COPD worsening (OR = 1.18, P = 0.003, and RR = 1.12 were higher for indacaterol than tiotropium. However, when one study with only severe COPD patients was removed from the meta-analysis, the difference in the incidence of COPD worsening between indacaterol and tiotropium became non-significant (OR = 1.13, P = 0.204, and RR = 1.09. The clinical efficacy and serious adverse events between indacaterol and tiotropium were equivocal in patients with moderate-to-severe COPD. Cough is a common complaint associated with indacaterol, and COPD worsening needs to be carefully monitored in severe COPD patients when treated with indacaterol.

    Background An increasing number of studies are reporting that ketamine could be treated as a novel antidepressant for major depressive disorder (MDD). Therefore, we performed this meta-analysis to comprehensively and systematically assess the efficacy of ketamine for treating patients with MDD. Method Randomized, double-blind, placebo-controlled studies on ketamine versus placebo for treating MDD were searched up to April 2016 in medical databases (PubMed, CCTR, Web of Science, Embase, CBM-disc, and CNKI). Three treatment time points (24 and 72 h, and day 7) were chosen. Response and remission rates were the main outcomes. The random effects model was used. An intention-to-treat analysis was conducted. Results Nine high-quality studies that included 368 patients were selected to compare the efficacy of ketamine to placebo. The therapeutic effects of ketamine at 24 and 72 h, and day 7 were found to be significantly better than placebo. Response and remission rates in the ketamine group at 24 and 72 h, and day 7 were 52.2% and 20.6%; 47.9% and 23.8%; and 39.8% and 26.2%, respectively. No significant heterogeneity existed, and the Egger’s test showed no publication bias. Conclusion These results indicated that ketamine could yield a good efficacy in the rapid treatment of MDD. Future large-scale clinical studies are needed to confirm our results and investigate the mid- and long-term efficacy of ketamine in treating MDD. PMID:27843321

  10. Comparative efficacy of selective serotonin reuptake inhibitors (SSRI) in treating major depressive disorder: a protocol for network meta-analysis of randomised controlled trials

    Jia, Yongliang; Zhu, Hongmei; Leung, Siu-wai

    2016-01-01

    Introduction There have been inconsistent findings from randomised controlled trials (RCTs) and systematic reviews on the efficacies of selective serotonin reuptake inhibitors (SSRIs) as the first-line treatment of major depressive disorder (MDD). Besides inconsistencies among randomised controlled trials (RCTs), their risks of bias and evidence grading have seldom been evaluated in meta-analysis. This study aims to compare the efficacy of SSRIs by conducting a Bayesian network meta-analysis, which will be the most comprehensive evaluation of evidence to resolve the inconsistency among previous studies. Methods and analyses SSRIs including citalopram, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline and vilazodone have been selected. Systematic database searching and screening will be conducted for the RCTs on drug treatment of patients with MDD according to pre-specified search strategies and selection criteria. PubMed, the Cochrane Library, EMBASE, ScienceDirect, the US Food and Drug Administration Website, ClinicalTrial.gov and WHO Clinical Trials will be searched. Outcome data including Hamilton Depression Rating Scale (HDRS), Montgomery-Åsberg Depression Rating Scale (MADRS) and Clinical Global Impression (CGI) from eligible RCTs will be extracted. The outcomes will be analysed as ORs and mean differences under a random-effects model. A Bayesian network meta-analysis will be conducted with WinBUGS software, to compare the efficacies of SSRIs. Subgroup and sensitivity analysis will be performed to explain the study heterogeneity and evaluate the robustness of the results. Meta-regression analysis will be conducted to determine the possible factors affecting the efficacy outcomes. The Cochrane risk of bias assessment tool will be used to assess the RCT quality, and the Grading of Recommendation, Assessment, Development and Evaluation will be used to assess the strength of evidence from the meta-analysis.

    2016-01-01

    To evaluate the efficacy of the adjunctive laser therapy in conventional non-surgical treatment of chronic periodontitis, an electronic search was performed through the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, MEDLINE, EMBASE, Scopus, Web of Science, China National Knowledge Infrastructure (CNKI), and China Biology Medicine (CBM) Disc, for relevant randomized controlled trials (RCTs) or quasi-RCTs. All the 12 included studies (11 RCTs and 1 quasi-RCT) were qualified for descriptive and quantitative analysis. Outcomes were divided into two groups according to the length of follow-ups (long term and short term). Subgroup analyses were performed based on the mode of laser (inside and outside mode). Among all included researches, reduction in probing depth (PD) and gain in clinical attachment level (CAL) were presented with the mean value and 95 % confidence interval, while bleeding on probing (BOP) was assessed descriptively. Meta-analysis suggested that adjunctive laser therapy reduced PD at 3 months [mean difference (MD) = -0.26, 95 % confidence interval (CI) range = -0.43 to -0.09, p = 0.003] but did not demonstrate significant effect on the CAL at either 3 months (MD = -0.03, 95 % CI range = -0.25 to 0.19, p = 0.79) or 6 months (MD = -0.11, 95 % CI range = -0.38 to 0.16, p = 0.43). Subgroup analyses indicated that laser therapy would be more effective when the probes were set up outside the periodontal pockets.

The aim of this meta-analysis is to compare the efficacy of epidural analgesia (EA and intravenous patient-controlled analgesia (IV-PCA following major spine surgery. We searched electronic databases, including the PubMed, EMBASE, Ovid and Cochrane databases, for randomized controlled trials (RCTs published before June 2016. The quality of the included trials was assessed using the Cochrane risk-of-bias tool. Random effects models were used to estimate the standardized mean differences (SMDs and relative risks (RRs, with the corresponding 95% confidence intervals (CI. Subgroup analyses stratified by the type of epidural-infused medication and epidural delivery were also performed. A total of 17 trials matched the inclusion criteria and were chosen for the following meta-analysis. Overall, EA provided significantly superior analgesia, higher patient satisfaction and decreased overall opioid consumption compared with IV-PCA following major spine surgery. Additionally, no differences were found in the side effects associated with these two methods of analgesia. Egger’s and Begg’s tests showed no significant publication bias. We suggest that EA is superior to IV-PCA for pain management after major spine surgery. More large-scale, high-quality trials are needed to verify these findings.

    2012-09-01

    Full Text Available Abstract Background Many studies reported that brief interventions are effective in reducing excessive drinking. This study aimed to assess the efficacy of a protocol of brief intervention for college students (BASICS, delivered face-to-face, to reduce risky alcohol consumption and negative consequences. Methods A systematic review with meta-analysis was performed by searching for randomized controlled trials (RCTs in Medline, PsycInfo, Web of Science and Cochrane Library databases. A quality assessment of RCTs was made by using a validated scale. Combined mean effect sizes, using meta-analysis random-effects models, were calculated. Results 18 studies were included in the review. The sample sizes ranged from 54 to 1275 (median = 212. All studies presented a good evaluation of methodological quality and four were found to have excellent quality. After approximately 12 months of follow-up, students receiving BASICS showed a significant reduction in alcohol consumption (difference between means = −1.50 drinks per week, 95% CI: -3.24 to −0.29 and alcohol-related problems (difference between means = −0.87, 95% CI: -1.58 to −0.20 compared to controls. Conclusions Overall, BASICS lowered both alcohol consumption and negative consequences in college students. Gender and peer factors seem to play an important role as moderators of behavior change in college drinking. Characteristics of BASICS procedure have been evaluated as more favorable and acceptable by students in comparison with others interventions or control conditions. Considerations for future researches were discussed.

    Full Text Available Single traumatising events are associated with an elevated rate of psychological disorders in children and adolescents. To date, it remains unclear whether early psychological interventions can reduce longer term psychological maladjustment.To systematically review the literature to determine the characteristics and efficacy of early psychological interventions in children and adolescents after a single, potentially-traumatising event.Systematic searches were conducted of all relevant bibliographic databases. Studies on early psychological interventions were included if the first session was conducted within 1 month of the event. Two independent observers assessed each study for eligibility, using pre-determined inclusion and exclusion criteria, and rated the study's methodological quality. A meta-analysis was conducted on the group effects between individuals allocated to intervention versus control groups. Hence, effect sizes (ES and confidence intervals were computed as well as heterogeneity and analogue-to-the ANOVA analyses.Seven studies (including four randomised controlled trials met the inclusion criteria. Depending on the specific outcome variable (e.g., dissociation, anxiety and arousal, small to large beneficial ES were noted. Although the meta-analysis revealed unexplained heterogeneity between the ES of the included studies, and although studies varied greatly with regards to their methodological quality and the interventions tested, findings suggest that early interventions should involve psycho-education, provide individual coping-skills and probably involve some kind of trauma exposure. Also, a stepped procedure that includes an initial risk screen and the provision of multiple sessions to those children at risk may be a promising strategy.To date, research on the effectiveness of early interventions in children after a potentially traumatising event remains scarce. However, our review suggests that early interventions may be

    OBJECT There is a paradigm shift toward rewarding providers for quality rather than volume. Complications appear to occur at a fairly consistent frequency in large aggregate data sets. Understanding how complications affect long-term patient-reported outcomes (PROs) following degenerative lumbar surgery is vital. The authors hypothesized that 90-day complications would adversely affect long-term PROs. METHODS Nine hundred six consecutive patients undergoing elective surgery for degenerative lumbar disease over a period of 4 years were enrolled into a prospective longitudinal registry. The following PROs were recorded at baseline and 12-month follow-up: Oswestry Disability Index (ODI) score, numeric rating scales for back and leg pain, quality of life (EQ-5D scores), general physical and mental health (SF-12 Physical Component Summary [PCS] and Mental Component Summary [MCS] scores) and responses to the North American Spine Society (NASS) satisfaction questionnaire. Previously published minimum clinically important difference (MCID) threshold were used to define meaningful improvement. Complications were divided into major (surgicalsite infection, hardware failure, new neurological deficit, pulmonary embolism, hematoma and myocardial infarction) and minor (urinary tract infection, pneumonia, and deep venous thrombosis). RESULTS Complications developed within 90 days of surgery in 13% (118) of the patients (major in 12% [108] and minor in 8% [68]). The mean improvement in ODI scores, EQ-5D scores, SF-12 PCS scores, and satisfaction at 3 months after surgery was significantly less in the patients with complications than in those who did not have major complications (ODI: 13.5 ± 21.2 vs 21.7 ± 19, lumbar spine surgery have significant impact on the short-term PROs. Patients with complications, however, do eventually achieve clinically meaningful outcomes and report satisfaction equivalent to those without major complications.

    Ankylosing spondylitis (AS) is an inflammatory rheumatic disease with impact on axial skeleton, peripheral joints and enthuses, and it may result in severe disabilities of those parts. Tumor necrosis factor-α (TNF-α) inhibitors are considered as an effective treatment for patients with active AS. In this study, we conducted a network meta-analysis to compare the clinical outcomes of active AS patients treated with TNF-α inhibitors. Randomized controlled trials (RCTs) evaluating the efficacy and safety of TNF-α inhibitors were retrieved in literature search and selected for meta-analysis. Changes in ASAS20 response, ASAS40 response and BASDAI 50% response were regarded as efficacy outcomes; serious adverse events (SAE) and all cause withdrawals were regarded as safety outcomes. Both traditional pairwise meta-analysis and network meta-analysis were performed. The results showed that adalimumab and infliximab had better clinical outcomes. Infliximab consistently appeared to be the most effective TNF-α inhibitors with a high risk of adverse events for patients with active AS; meanwhile, adalimumab ranked highest with respect to adverse effects with efficacy secondary to infliximab. As a result, we were unable to conclude the optimal TNF-α inhibitor and this issue should be solved by future researchers. PMID:27667027

    2014-06-01

    Full Text Available BACKGROUND: Gastrointestinal nematode infections, such as Haemonchus contortus and Mecistocirrus digitatus, are ranked in the top twenty diseases affecting small-holder farmers' livestock, yet research into M. digitatus, which infects cattle and buffalo in Asia is limited. Intestine-derived native protein vaccines are effective against Haemonchus, yet the protective efficacy of intestine-derived M. digitatus proteins has yet to be determined. METHODOLOGY/PRINCIPAL FINDINGS: A simplified protein extraction protocol (A is described and compared to an established method (B for protein extraction from H. contortus. Proteomic analysis of the H. contortus and M. digitatus protein extracts identified putative vaccine antigens including aminopeptidases (H11, zinc metallopeptidases, glutamate dehydrogenase, and apical gut membrane polyproteins. A vaccine trial compared the ability of the M. digitatus extract and two different H. contortus extracts to protect sheep against H. contortus challenge. Both Haemonchus fractions (A and B were highly effective, reducing cumulative Faecal Egg Counts (FEC by 99.19% and 99.89% and total worm burdens by 87.28% and 93.64% respectively, compared to the unvaccinated controls. There was no effect on H. contortus worm burdens following vaccination with the M. digitatus extract and the 28.2% reduction in cumulative FEC was not statistically significant. However, FEC were consistently lower in the M. digitatus extract vaccinates compared to the un-vaccinated controls from 25 days post-infection. CONCLUSIONS/SIGNIFICANCE: Similar, antigenically cross-reactive proteins are found in H. contortus and M. digitatus; this is the first step towards developing a multivalent native vaccine against Haemonchus species and M. digitatus. The simplified protein extraction method could form the basis for a locally produced vaccine against H. contortus and, possibly M. digitatus, in regions where effective cold chains for vaccine

    We investigated the efficacy of drugs used to treat brain edema in a rat acute cerebral infarction model by MRI image analysis. Twenty-six Sprague-Dawley rats were anesthetized with halothane, and the right middle cerebral artery was permanently occluded via a transvascular approach using a nylon 2-0 suture. At 24 hours after the occlusion, axial T{sub 2}-weighted MRI images were taken before and 2 hours after intraperitoneal administration of a test drug. After the administration of 1.7 g/kg glycerol (n=9), 3.3 g/kg mannitol (n=9) or 17 mg/kg furosemide (n=8), the high intensity area (HIA) in the whole brain amounted to 92% (p<0.01), 94% (p=0.07), or 95% (p=0.03), respectively as compared to the corresponding HIA before administration. The HIA in the cerebral cortex amounted to 87% (p<0.01), 89% (p=0.03), or 98% (p=0.47), and that in the striatum to 102%, 106%, or 87% (p<0.05), respectively. The signal intensity change (before{yields}after) was 54{yields}49 (p<0.01), 54{yields}50 (p<0.01), or 55{yields}54 in the left side normal cortex; 102{yields}97 (p<0.0l), 100{yields}98, or 98{yields}97 in the injured side cortex; and 100{yields}93 (p<0.0l), 94{yields}88 (p=0.03), or 94{yields}94 in the injured side striatum, respectively. Improvement of edema by the drugs was observed as a reduction in HIA and a decrease in signal intensity on MRI, and the changes were significant in the case of administration of each of glycerol, mannitol and furosemide.

    Objective: This was a prospective analysis of epidural tramadol as a single analgesic agent delivered through intraoperatively placed epidural catheter for postoperative pain relief after spinal fusion procedures in terms of efficacy and cost. Materials and Methods: Twenty patients who underwent spinal fusion procedures were included in the study. After completion of the procedure, an epidural catheter was placed at the highest level of exposed dura and brought out through a separate tract. Postoperatively, tramadol was infused into the epidural space via the catheter at a dose of 1 mg/kg diluted in 10 ml of saline. The dosage frequency was arbitrarily fixed at every 6 h during the first 2 days and thereafter reduced to every 8 h after the first 2 days till day 5. Conventional intravenous analgesics were used only if additional analgesia was required as assessed by visual analog scale (VAS). Results: Patients’ VAS score was assessed every 4 h from the day of surgery. Patients with a VAS score of 6 or more were given additional analgesia in the form of intravenous paracetamol. Of the twenty patients, eight patients needed additional analgesia during the first 24 h and none required additional analgesia after the first 24 h. The median VAS score was 7 within the first 24 h and progressively declined thereafter. Epidural tramadol was noted to be many times cheaper than conventional parenteral analgesics. Conclusion: Epidural tramadol infusion is safe and effective as a standalone analgesic after open spinal fusion surgery, especially after the 1st postoperative day. Intraoperative placement of the epidural catheter is a simple way of delivering tramadol to the epidural space. The cost of analgesia after spinal fusion surgery can be reduced significantly using epidural tramadol alone. PMID:28149082

    Full Text Available Objective To evaluate the clinical efficacy and safety of motherwort injection and oxytocin in preventing postpartum hemorrhage after vaginal delivery. Methods Data of randomly controlled trials (RCTs of motherwort injection and oxytocin in preventing postpartum hemorrhage after vaginal delivery were collected by searching PubMed (1980-2013.9, Wiley Online Library (1990-2013.9, Embase (1990-2013.9, CNKI (1990-2013.9, VIP database (1990-2013.9 and WanFang Data (1990-2013.9. The amount and incidence of postpartum hemorrhage and quantity of blood loss, as well as the incidence of postpartum morbidity were then collected in those puerperal women treated with motherwort injection and oxytocin. The quality of included studies was assessed according to Cochrane Systematic Review, and Meta-analysis was conducted by RevMan 5.1 software. Results A total of 13 studies involving 2186 patients were included. Compared with oxytocin group, motherwort and oxytocin decreased the amount of vaginal bleeding within 2 hours after delivery and 24 hours after delivery. Furthermore, motherwort and oxytocin significantly decreased the incidence of postpartum hemorrhage (RR=0.30, 95%CI 0.19-0.47, P<0.00001. No difference was found between the two groups in the postpartum adverse reaction rate (RR=0.63, 95%CI 0.37-1.05, P=0.08. Conclusions Motherwort injection and oxytocin are effective in preventing postpartum hemorrhage after vaginal delivery, and they can effectively reduce incidence of postpartum hemorrhage and the amount of blood loss without increasing the side effects in patients.

    2017-01-06

    Although vaccines would be the ideal tool for control, prevention, elimination, and eradication of many infectious diseases, developing of parasites vaccines such as malaria vaccine is very complex. The most advanced malaria vaccine candidate is RTS,S, a pre-erythrocytic vaccine for which pivotal phase III trial design is underway. Few recent malaria vaccine review articles have attempted to outline of all clinical trials that have occurred globally and no meta-analysis was performed on efficacy of Phase 3 Trial of RTS, S/AS01 Malaria vaccine up to now in infants. Therefore, a systematic review and meta-analysis was carried out to review new and existing data on efficacy of Phase 3 Trial of RTS, S/AS01 Malaria Vaccine in infants. The electronic databases searched were Pubmed (1965-present) and Web of Science (1970-present) (Search date: May, 2016). After full-text review of the papers evaluating clinical/severe malaria in several well-designed phase III field efficacy trials, 5 were determined to meet the eligibility criteria for inclusion in the systematic review. Four out of the 5 publications dealing with efficacy of Phase 3 Trial of RTS, S/AS01 malaria vaccine were included in the qualitative analysis. Pooled estimate of vaccine efficacy in clinical and severe malaria in children aged 5-17 mo was 29% (95% CL: 19%-46%) and 39% (95% CI 20%-74%), while this estimate vaccine in clinical and severe malaria in children aged 6-12 mo was 19% (95% CI 14%-24%) and 21 (95% CI 19%-37%), respectively. On the other hand, higher VE was seen in both per- protocol and intention-to-treat population in children aged 5-17 than the children aged 6-12 mo. The results of this meta-analysis suggest that this candidate malaria vaccine has relatively little efficacy, and the vaccine apparently will not meet the goal of malaria eradication by itself.

    Alcohol consumption is strongly associated with cigarette smoking in young adults. The primary aim of this investigation was to complete a pilot evaluation of the efficacy of an integrated intervention that targets both cigarette smoking and binge drinking on the cigarette smoking and binge behavior of young adults at 6-month follow-up. Participants were 95 young adult (M=24.3; SD=3.5 years) smokers (≥1 cigarettes per day) who binge drink (≥1 time per month) and who were randomly assigned to standard treatment (n=47) involving six individual treatment visits plus eight weeks of nicotine patch therapy or the identical smoking cessation treatment integrated with a binge drinking intervention (integrated intervention; n=48). Using an intent-to-treat analysis for tobacco abstinence, at both 3 month end of treatment and 6 month follow-up, more participants who received integrated intervention were biochemically confirmed abstinent from tobacco than those who received standard treatment at 3 months (19% vs. 9%, p=0.06) and 6 months (21% vs. 9%, p=0.05). At 6 months, participants who completed the study and who received integrated intervention consumed fewer drinks per month (psmoking cessation and reduces binge drinking compared to standard treatment.

  12. Progesterone therapy, endothelial function and cardiovascular risk factors: a 3-month randomized, placebo-controlled trial in healthy early postmenopausal women.

    Jerilynn C Prior

    Full Text Available BACKGROUND: Progesterone is effective treatment for hot flushes/night sweats. The cardiovascular effects of progesterone therapy are unknown but evidence suggests that premenopausal normal estradiol with also normal progesterone levels may provide later cardiovascular protection. We compared the effects of progesterone to placebo on endothelial function, weight, blood pressure, metabolism, lipids, inflammation and coagulation. METHODS AND RESULTS: We conducted a randomized, double-blind, 3-month placebo-controlled trial of progesterone (300 mg daily among 133 healthy postmenopausal women in Vancouver, Canada from 2003-2009. Endothelial function by venous occlusion plethysmography was a planned primary outcome. Enrolled women were 1-11 y since last menstruation, not using hormones (for >6 months, non-smoking, without diabetes, hypertension, heart disease or their medications. Randomized (1∶1 women (55 ± 4 years, body mass index 25 ± 3 initially had normal blood pressure, fasting lipid, glucose and electrocardiogram results. Endothelial function (% forearm blood flow above saline was not changed with progesterone (487 ± 189%, n = 18 compared with placebo (408 ± 278%, n = 16 (95% CI diff [-74 to 232], P = 0.30. Progesterone (n = 65 and placebo (n = 47 groups had similar changes in systolic and diastolic blood pressure, resting heart rate, weight, body mass index, waist circumference, total cholesterol, low-density lipoprotein cholesterol and triglyceride levels. High-density lipoprotein was lower (-0.14 mmol/L, P = 0.001 on progesterone compared with placebo. Fasting glucose, hs-C-reactive protein, albumin and D-dimer changes were all comparable to placebo. Framingham General Cardiovascular Risk Profile scores were initially low and remained low with progesterone therapy and not statistically different from placebo. CONCLUSIONS: Results indicate that progesterone has short-term cardiovascular safety. Endothelial

    2012-06-01

    Full Text Available Abstract Background Approximately 35 million people world-wide have Alzheimer’s disease and this is projected to nearly double by 2030. Cognitive enhancers, including cholinesterase inhibitors (for example, donepezil, galantamine and rivastigmine and memantine (N-methyl-D-aspartic acid (NMDA receptor antagonist have been approved for the treatment of Alzheimer’s disease in many countries. Our objective is to evaluate the comparative effectiveness, safety, and cost of cognitive enhancers for Alzheimer’s disease through a systematic review. Methods/design Studies examining the efficacy, safety, and cost of cognitive enhancers compared to placebo, supportive care, and other cognitive enhancers for Alzheimer’s patients will be included. The primary outcome is cognition and secondary outcomes include function, behavior, quality of life, safety, and cost. Experimental studies (randomized controlled trials, quasi-randomized controlled trials, controlled clinical trials, quasi-experimental studies (controlled before-after, interrupted time series, and observational studies (cohort, case–control studies will be eligible for inclusion. Inclusion will not be limited by publication status, time period or language of dissemination. We will search electronic databases (for example, MEDLINE, Cochrane Central Register of Controlled Trials, EMBASE, CINAHL, Ageline from inception onwards. The electronic database search will be supplemented by searching for grey literature (for example, conference proceedings, searches in Google and relevant organization websites. Two reviewers will independently screen the studies for inclusion using the eligibility criteria established a priori and independently extract data. Risk of bias will be assessed using the Cochrane Risk of Bias tool for experimental and quasi-experimental studies and the Newcastle Ottawa Scale for observational studies. If deemed appropriate, meta-analysis and network (that is, indirect

  15. Efficacy and Safety of Alfuzosin as Medical Expulsive Therapy for Ureteral Stones: A Systematic Review and Meta-Analysis.

    Chenli Liu

    Full Text Available Alfuzosin has been widely used to treat benign prostatic hyperplasia and prostatitis, and is claimed to be a selective agent for the lower urinary tract with low incidence of adverse side-effects and hypotensive changes. Recently, several randomized controlled trials have reported using Alfuzosin as an expulsive therapy of ureteral stones. Tamsulosin, another alpha blocker, has also been used as an agent for the expulsive therapy for ureteral stones. It is unclear whether alfuzosin has similar efficacy as Tamsulosin in the management of ureteral stones.To perform a systematic review and analysis of literatures comparing Alfuzosin with Tamsulosin or standard conservative therapy for the treatment of ureteral stones less than 10 mm in diameter.A systematic literature review was performed in December 2014 using Pubmed, Embase, and the Cochrane library databases to identify relevant studies. All randomized and controlled trials were included. A subgroup analysis was performed comparing Alfuzosin with control therapy on the management of distal ureteral stones.Alfuzosin provided a significantly higher stone-free rate than the control treatments (RR: 1.85; 95% confidence interval [CI], 1.35-2.55; p<0.001, and a shorter stone expulsion time (Weighted mean difference [WMD]: -4.20 d, 95%CI, -6.19 to -2.21; p<0.001, but it has a higher complication rate (RR: 2.02; 95% CI, 1.30-3.15; p<0.01. When Alfuzosin was compared to Tamsulosin, there was no significant difference in terms of stone-free rate (RR: 0.90; 95% CI, 0.79-1.02; p = 0.09 as well as the stone expulsion time (WMD: 0.52 d, 95%CI, -1.61 to 2.64; p = 0.63. The adverse effects of Alfuzosin were similar to those of Tamsulosin (RR: 0.88; 95% CI, 0.61-1.26; p = 0.47.Alfuzosin is a safe and effective agent for the expulsive therapy of ureteral stones smaller than 10 mm in size. It is more effective than therapeutic regiment without alpha blocker. It is equivalent to Tamsulosin in its effectiveness and

  16. Affective Balance, Team Prosocial Efficacy and Team Trust: A Multilevel Analysis of Prosocial Behavior in Small Groups.

    Cuadrado, Esther; Tabernero, Carmen

    2015-01-01

    Little research has focused on how individual- and team-level characteristics jointly influence, via interaction, how prosocially individuals behave in teams and few studies have considered the potential influence of team context on prosocial behavior. Using a multilevel perspective, we examined the relationships between individual (affective balance) and group (team prosocial efficacy and team trust) level variables and prosocial behavior towards team members. The participants were 123 students nested in 45 small teams. A series of multilevel random models was estimated using hierarchical linear and nonlinear modeling. Individuals were more likely to behave prosocially towards in-group members when they were feeling good. Furthermore, the relationship between positive affective balance and prosocial behavior was stronger in teams with higher team prosocial efficacy levels as well as in teams with higher team trust levels. Finally, the relevance of team trust had a stronger influence on behavior than team prosocial efficacy.

  18. The impact of self-efficacy, alexithymia and multiple traumas on posttraumatic stress disorder and psychiatric co-morbidity following epileptic seizures: a moderated mediation analysis.

    Chung, Man Cheung; Allen, Rachel D; Dennis, Ian

    2013-12-30

    This study investigated the incidence of posttraumatic stress disorder (PTSD) and psychiatric co-morbidity following epileptic seizure, whether alexithymia mediated the relationship between self-efficacy and psychiatric outcomes, and whether the mediational effect was moderated by the severity of PTSD from other traumas. Seventy-one (M=31, F=40) people with a diagnosis of epilepsy recruited from support groups in the United Kingdom completed the Posttraumatic Stress Diagnostic Scale, the Hospital Anxiety and Depression Scale, the Toronto Alexithymia Scale-20 and the Generalized Self-Efficacy Scale. They were compared with 71 people (M=29, F=42) without epilepsy. For people with epilepsy, 51% and 22% met the diagnostic criteria for post-epileptic seizure PTSD and for PTSD following one other traumatic life event respectively. For the control group, 24% met the diagnostic criteria for PTSD following other traumatic life events. The epilepsy group reported significantly more anxiety and depression than the control. Partial least squares (PLS) analysis showed that self-efficacy was significantly correlated with alexithymia, post-epileptic seizure PTSD and psychiatric co-morbidity. Alexithymia was also significantly correlated with post-epileptic seizure PTSD and psychiatric co-morbidity. Mediation analyses confirmed that alexithymia mediated the path between self-efficacy and post-epileptic seizure PTSD and psychiatric co-morbidity. Moderated mediation also confirmed that self-efficacy and PTSD from one other trauma moderated the effect of alexithymia on outcomes. To conclude, people can develop posttraumatic stress disorder symptoms and psychiatric co-morbidity following epileptic seizure. These psychiatric outcomes are closely linked with their belief in personal competence to deal with stressful situations and regulate their own functioning, to process rather than defend against distressing emotions, and with the degree of PTSD from other traumas.

  19. Systematic review and meta-analysis of the efficacy and safety of existing TNF blocking agents in treatment of rheumatoid arthritis.

    Kalle J Aaltonen

    Full Text Available BACKGROUND AND OBJECTIVES: Five-tumour necrosis factor (TNF-blockers (infliximab, etanercept, adalimumab, certolizumab pegol and golimumab are available for treatment of rheumatoid arthritis. Only few clinical trials compare one TNF-blocker to another. Hence, a systematic review is required to indirectly compare the substances. The aim of our study is to estimate the efficacy and the safety of TNF-blockers in the treatment of rheumatoid arthritis (RA and indirectly compare all five currently available blockers by combining the results from included randomized clinical trials (RCT. METHODS: A systematic literature review was conducted using databases including: MEDLINE, SCOPUS (including EMBASE, Cochrane library and electronic search alerts. Only articles reporting double-blind RCTs of TNF-blockers vs. placebo, with or without concomitant methotrexate (MTX, in treatment of RA were selected. Data collected were information of patients, interventions, controls, outcomes, study methods and eventual sources of bias. RESULTS: Forty-one articles reporting on 26 RCTs were included in the systematic review and meta-analysis. Five RCTs studied infliximab, seven etanercept, eight adalimumab, three golimumab and three certolizumab. TNF-blockers were more efficacious than placebo at all time points but were comparable to MTX. TNF-blocker and MTX combination was superior to either MTX or TNF-blocker alone. Increasing doses did not improve the efficacy. TNF-blockers were relatively safe compared to either MTX or placebo. CONCLUSIONS: No single substance clearly rose above others in efficacy, but the results of the safety analyses suggest that etanercept might be the safest alternative. Interestingly, MTX performs nearly identically considering both efficacy and safety aspects with a margin of costs.

    2016-05-01

    The aim of this study was to assess the relative efficacy and tolerability of duloxetine, pregabalin, and milnacipran at the recommended doses in patients with fibromyalgia. Randomized controlled trials (RCTs) examining the efficacy and safety of duloxetine 60 mg, pregabalin 300 mg, pregabalin 150 mg, milnacipran 200 mg, and milnacipran 100 mg compared to placebo in patients with fibromyalgia were included in this Bayesian network meta-analysis. Nine RCTs including 5140 patients met the inclusion criteria. The proportion of patients with >30 % improvement from baseline in pain was significantly higher in the duloxetine 60 mg, pregabalin 300 mg, milnacipran 100 mg, and milnacipran 200 mg groups than in the placebo group [pairwise odds ratio (OR) 2.33, 95 % credible interval (CrI) 1.50-3.67; OR 1.68, 95 % CrI 1.25-2.28; OR 1.62, 95 % CrI 1.16-2.25; and OR 1.61; 95 % CrI 1.15-2.24, respectively]. Ranking probability based on the surface under the cumulative ranking curve (SUCRA) indicated that duloxetine 60 mg had the highest probability of being the best treatment for achieving the response level (SUCRA = 0.9431), followed by pregabalin 300 mg (SUCRA = 0.6300), milnacipran 100 mg (SUCRA = 0.5680), milnacipran 200 mg (SUCRA = 0.5617), pregabalin 150 mg (SUCRA = 0.2392), and placebo (SUCRA = 0.0580). The risk of withdrawal due to adverse events was lower in the placebo group than in the pregabalin 300 mg, duloxetine 60 mg, milnacipran 100 mg, and milnacipran 200 mg groups. However, there was no significant difference in the efficacy and tolerability between the medications at the recommended doses. Duloxetine 60 mg, pregabalin 300 mg, milnacipran 100 mg, and milnacipran 200 mg were more efficacious than placebo. However, there was no significant difference in the efficacy and tolerability between the medications at the recommended doses.

    Full Text Available Background. Huachansu, the sterilized water extract of Bufo bufo gargarizans toad skin, is used in China to alleviate the side-effects and enhance the therapeutic effect of chemotherapy in advanced non-small-cell lung cancer (NSCLC. We conducted a meta-analysis to assess Huachansu’s efficacy. Methods. We extensively searched electronic databases (CENTRAL, EMBASE, MEDLINE, CBM, Cochrane Library, CNKI, CEBM, WFDP, CSCD, CSTD, and IPA for randomized controlled trials containing Huachansu plus chemotherapy as the test group and chemotherapy as the control group. Seventeen trials were selected based on the selection criteria. The pooled relative ratio (RR of indicators with 95% confidence interval (95% CI was calculated for efficacy evaluation. Results. The meta-analysis demonstrated a statistically significant improvement in objective tumor response, one-year survival, Karnofsky performance status, pain relief, and alleviation of severe side-effects (nausea and vomiting, leukocytopenia in the test group as compared to the control group, but no significant difference in thrombocytopenia. Conclusions. This study demonstrated the efficacy of Huachansu combined with chemotherapy in the treatment of advanced NSCLC. However, limitations exist and high-quality trials are needed for further verification.

    2014-11-01

    Full Text Available Introduction: The National AIDS Plan and the Spanish AIDS study group (GESIDA panel of experts propose “preferred regimens” of antiretroviral treatment (ART as initial therapy in HIV-infected patients for 2013 [1]. All these regimens are triple therapy regimens. The Gardel Study assessed the efficacy and safety of a dual therapy (DT combination of lopinavir/ritonavir (LPV/r 400/100 mg BID+ lamivudine (3TC 150 mg BID [2]. The objective of this study is to evaluate the costs and efficiency of initiating treatment with the GESIDA “preferred regimens” and DT. Materials and Methods: Economic assessment of costs and efficiency (cost/efficacy through decision tree analysis models. Efficacy was defined as the probability of having viral load <50 copies/mL at week 48, in an intention-to-treat analysis. Cost of initiating treatment with an ART regime was defined as the costs of ART and its consequences (adverse effects, changes of ART regime and drug resistance tests during the first 48 weeks. The payer perspective (Spanish National Health System was applied considering only differential direct costs: ART (official prizes, management of adverse effects, resistance tests, and determination of HLA B*5701. The setting is Spain and the costs are those of 2013. A sensitivity deterministic analysis was conducted, building three scenarios for each regime: base, most favourable and most unfavourable cases. Results: In the base case scenario, the cost of initiating treatment ranges from 5138 euros for DT, to 12,059 euros for tenofovir DF/emtricitabine (TDF/FTC+raltegravir (RAL. The efficacy ranges between 0.66 for abacavir (ABC/3TC+LPV/r and ABC/3TC+atazanavir (ATV/r, and 0.88 for DT. Efficiency, in terms of cost/efficacy, varies between 5817 and 13,930 euros per responder at 48 weeks, for DT and TDF/FTC+RAL respectively. DT is the most efficient regimen in the most favourable (5503 euros per responder and most unfavourable (6169 euros per responder

  4. The efficacy of traditional Chinese Medical Exercise for Parkinson's disease: a systematic review and meta-analysis.

    Yan Yang

    Full Text Available Several studies assessed the efficacy of traditional Chinese medical exercise in the management of Parkinson's disease (PD, but its role remained controversial. Therefore, the purpose of this systematic review is to evaluate the evidence on the effect of traditional Chinese medical exercise for PD.Seven English and Chinese electronic databases, up to October 2014, were searched to identify relevant studies. The PEDro scale was employed to assess the methodological quality of eligible studies. Meta-analysis was performed by RevMan 5.1 software.Fifteen trials were included in the review. Tai Chi and Qigong were used as assisting pharmacological treatments of PD in the previous studies. Tai Chi plus medication showed greater improvements in motor function (standardized mean difference, SMD, -0.57; 95% confidence intervals, CI, -1.11 to -0.04, Berg balance scale (BBS, SMD, -1.22; 95% CI -1.65 to -0.80, and time up and go test (SMD, -1.06; 95% CI -1.44 to -0.68. Compared with other therapy plus medication, Tai Chi plus medication also showed greater gains in motor function (SMD, -0.78; 95% CI -1.46 to -0.10, BBS (SMD, -0.99; 95% CI -1.44 to -0.54, and functional reach test (SMD, -0.77; 95% CI -1.51 to -0.03. However, Tai Chi plus medication did not showed better improvements in gait or quality of life. There was not sufficient evidence to support or refute the effect of Qigong plus medication for PD.In the previous studies, Tai Chi and Qigong were used as assisting pharmacological treatments of PD. The current systematic review showed positive evidence of Tai Chi plus medication for PD of mild-to-moderate severity. So Tai Chi plus medication should be recommended for PD management, especially in improving motor function and balance. Qigong plus medication also showed potential gains in the management of PD. However, more high quality studies with long follow-up are warrant to confirm the current findings.

    Full Text Available BACKGROUND: The UK Prospective Diabetes Study showed that metformin decreases mortality compared to diet alone in overweight patients with type 2 diabetes mellitus. Since then, it has been the first-line treatment in overweight patients with type 2 diabetes. However, metformin-sulphonylurea bitherapy may increase mortality. METHODS AND FINDINGS: This meta-analysis of randomised controlled trials evaluated metformin efficacy (in studies of metformin versus diet alone, versus placebo, and versus no treatment; metformin as an add-on therapy; and metformin withdrawal against cardiovascular morbidity or mortality in patients with type 2 diabetes. We searched Medline, Embase, and the Cochrane database. Primary end points were all-cause mortality and cardiovascular death. Secondary end points included all myocardial infarctions, all strokes, congestive heart failure, peripheral vascular disease, leg amputations, and microvascular complications. Thirteen randomised controlled trials (13,110 patients were retrieved; 9,560 patients were given metformin, and 3,550 patients were given conventional treatment or placebo. Metformin did not significantly affect the primary outcomes all-cause mortality, risk ratio (RR=0.99 (95% CI: 0.75 to 1.31, and cardiovascular mortality, RR=1.05 (95% CI: 0.67 to 1.64. The secondary outcomes were also unaffected by metformin treatment: all myocardial infarctions, RR=0.90 (95% CI: 0.74 to 1.09; all strokes, RR=0.76 (95% CI: 0.51 to 1.14; heart failure, RR=1.03 (95% CI: 0.67 to 1.59; peripheral vascular disease, RR=0.90 (95% CI: 0.46 to 1.78; leg amputations, RR=1.04 (95% CI: 0.44 to 2.44; and microvascular complications, RR=0.83 (95% CI: 0.59 to 1.17. For all-cause mortality and cardiovascular mortality, there was significant heterogeneity when including the UK Prospective Diabetes Study subgroups (I(2=41% and 59%. There was significant interaction with sulphonylurea as a concomitant treatment for myocardial infarction (p=0

    Full Text Available Abstract Background Recommendations given for intravenous iron treatment are typically not supported by a high level of evidence. This meta-analysis addressed this by summarising the available date from clinical trials of ferric carboxymaltose using clinical trial reports and published reports. Methods Clinical trial reports were supplemented by electronic literature searches comparing ferric carboxymaltose with active comparators or placebo. Various outcomes were sought for efficacy (attainment of normal haemoglobin (Hb, increase of Hb by a defined amount, for example, together with measures of harm, including serious adverse events and deaths. Results Fourteen studies were identified with 2,348 randomised patients exposed to ferric carboxymaltose, 832 to oral iron, 762 to placebo, and 384 to intravenous iron sucrose. Additional data were available from cohort studies. Intravenous ferric carboxymaltose was given up to the calculated iron deficit (up to 1,000 mg in one week for iron deficiency anaemia secondary to chronic kidney disease, blood loss in obstetric and gynaecological conditions, gastrointestinal disease, and other conditions like heart failure. The most common comparator was oral iron, and trials lasted 1 to 24 weeks. Intravenous ferric carboxymaltose improved mean Hb, serum ferritin, and transferrin saturation levels; the mean end-of-trial increase over oral iron was, for Hb 4.8 (95% confidence interval 3.3 to 6.3 g/L, for ferritin 163 (153 to 173 μg/L, and for transferrin saturation 5.3% (3.7 to 6.8%. Ferric carboxymaltose was significantly better than comparator in achievement of target Hb increase (number needed to treat (NNT 6.8; 5.3 to 9.7 and target Hb NNT (5.9; 4.7 to 8.1. Serious adverse events and deaths were similar in incidence in ferric carboxymaltose and comparators; rates of constipation, diarrhoea, and nausea or vomiting were lower than with oral iron. Conclusions This review examined the available trials of

    Antiretroviral therapy (ART) is a lifelong treatment. To date, ART adherence is suboptimal for most patients in resource-poor settings. Previous research indicates that medication side effects are perceived to be a significant barrier of high ART adherence. Data regarding the role of adherence self-efficacy in mediating the relationship between side effects from ART and adherence to ART are limited; thus, this study examines this potential mediational role of self-efficacy. A cross-sectional survey of 2987 people living with HIV aged ≥18 years was conducted in 2012-2013 in Guangxi Autonomous Region (Guangxi) which has one of the fastest-growing HIV rates in China. Of the total sample, 2146 (72.1%) participants had initiated ART. Participants reported the number of days of completing the daily dose of ART in the past month; adherence was defined as completing the daily dose at least 28 days in the last month (≥90%). Side effects were significantly negatively related to adherence to ART. Mediation analyses indicated that adherence self-efficacy significantly mediated the side effects-adherence relationship. Future interventions to increase adherence self-efficacy and effective coping with side effects among HIV patients are needed in order to improve their ART adherence.

    2012-01-01

    Objective: The aim of this study was to compare the effect of 131I therapy of different clinical stages in postopera-tive patients with papillary thyroid carcinoma (PTC). Methods: Eighty-seven PTC patients after surgery ablated with high doses of 131I from 2004 to 2010 were retrospectively reviewed. The efficacy of 131I therapy was assessed by three diagnostics that serum thyroglobulin (Tg) was normal or significantly reduced, 131I whole body scan (131I-WBS) was negative or the metas-tases shrank or the number of them decreased and new metastases was not found in cervical ultrasound examination. The χ2 test was used to analyze 3 factors which might affect the therapeutic efficacy of 131I in patients of different clinical period, including different surgical ways (total or subtotal thyroidectomy along with half or double sides neck lymph node dissection), age ( 0.25, P < 0.005, P < 0.01). The effective rate was 91.67% (44) in 48 cases undergoing total thyroidectomy; the effective rate was 53.85% (21) in 39 patients undergoing subtotal thyroidectomy. There was a significant difference between the two groups above by χ2 test (χ2 = 16.291; P < 0.005). Conclusion: The efficacy of 131I ablation of stage I and stage III in postoperative PTC patients was almost alike, while the efficacy of stage IV descended markedly. The results was mainly determined by residual thyroid tissue size because of different surgical modus.

    Natalizumab (Tysabri(®)) is highly efficacious in controlling disease activity in relapsing multiple sclerosis (MS) patients. As it is one of the more recent therapies for MS, there remains a need for long-term safety and efficacy data of natalizumab in a clinical practice setting. The Tysabri observational program (TOP) is an open-label, multicenter, multinational, prospective observational study, aiming to recruit up to 6,000 patients with relapsing-remitting MS from Europe, Canada and Australia. The objectives of this study are to collect long-term safety and efficacy data on disease activity and disability progression. We report here the interim results of the 563 patients included in TOP between December 2007 and 2012 from Belgium. This patient cohort was older at baseline, had longer disease duration, higher neurological impairment, and a higher baseline annualized relapse rate, when compared to patients included in the pivotal phase III AFFIRM trial. Nevertheless, the efficacy of natalizumab was comparable. The annualized relapse rate on treatment was reduced by 90.70 % (p < 0.0001) with a cumulative probability of relapse of 26.87 % at 24 months. The cumulative probabilities of sustained disability improvement and progression at 24 months were 25.68 and 9.01 %, respectively. There were no new safety concerns over the follow-up period. Two cases of progressive multifocal leukoencephalopathy were diagnosed. Our results are consistent with other observational studies in the post-marketing setting.

  5. Development of a Short-Form Measure of Science and Technology Self-efficacy Using Rasch Analysis

    Lamb, Richard L.; Vallett, David; Annetta, Leonard

    2014-10-01

    Despite an increased focus on science, technology, engineering, and mathematics (STEM) in U.S. schools, today's students often struggle to maintain adequate performance in these fields compared with students in other countries (Cheek in Thinking constructively about science, technology, and society education. State University of New York, Albany, 1992; Enyedy and Goldberg 2004; Mandinach and Lewis 2006). In addition, despite considerable pressure to promote the placement of students into STEM career fields, U.S. placement is relatively low (Sadler et al. in Sci Educ 96(3):411-427, 2012; Subotnik et al. in Identifying and developing talent in science, technology, engineering, and mathematics (STEM): an agenda for research, policy and practice. International handbook, part XII, pp 1313-1326, 2009). One explanation for the decline of STEM career placement in the U.S. rests with low student affect concerning STEM concepts and related content, especially in terms of self-efficacy. Researchers define self-efficacy as the internal belief that a student can succeed in learning, and that understanding student success lies in students' externalized actions or behaviors (Bandura in Psychol Rev 84(2):191-215, 1977). Evidence suggests that high self-efficacy in STEM can result in student selection of STEM in later educational endeavors, culminating in STEM career selection (Zeldin et al. in J Res Sci Teach 45(9):1036-1058, 2007). However, other factors such as proficiency play a role as well. The lack of appropriate measures of self-efficacy can greatly affect STEM career selection due to inadequate targeting of this affective trait and loss of opportunity for early intervention by educators. Lack of early intervention decreases selection of STEM courses and careers (Valla and Williams in J Women Minor Sci Eng 18(1), 2012; Lent et al. in J Couns Psychol 38(4), 1991). Therefore, this study developed a short-form measure of self-efficacy to help identify students in need of

    Full Text Available Renal ischemia-reperfusion injury (IRI is a major cause of kidney damage after e.g. renal surgery and transplantation. Ischemic postconditioning (IPoC is a promising treatment strategy for renal IRI, but early clinical trials have not yet replicated the promising results found in animal studies.We present a systematic review, quality assessment and meta-analysis of the preclinical evidence for renal IPoC, and identify factors which modify its efficacy.We identified 39 publications studying >250 control animals undergoing renal IRI only and >290 animals undergoing renal IRI and IPoC. Healthy, male rats undergoing warm ischemia were used in the vast majority of studies. Four studies applied remote IPoC, all others used local IPoC. Meta-analysis showed that both local and remote IPoC ameliorated renal damage after IRI for the outcome measures serum creatinine, blood urea nitrogen and renal histology. Subgroup analysis indicated that IPoC efficacy increased with the duration of index ischemia. Measures to reduce bias were insufficiently reported.High efficacy of IPoC is observed in animal models, but factors pertaining to the internal and external validity of these studies may hamper the translation of IPoC to the clinical setting. The external validity of future animal studies should be increased by including females, comorbid animals, and transplantation models, in order to better inform clinical trial design. The severity of renal damage should be taken into account in the design and analysis of future clinical trials.

  8. Efficacy of Turmeric Extracts and Curcumin for Alleviating the Symptoms of Joint Arthritis: A Systematic Review and Meta-Analysis of Randomized Clinical Trials.

    Daily, James W; Yang, Mini; Park, Sunmin

    2016-08-01

    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 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 of turmeric for arthritis.

    Full Text Available Objectives. This study was conducted to review systematically adjunctive treatments for weight reduction in patients with schizophrenia and compare efficacies of clinical trials through meta-analysis, so as to provide effective clinical guideline regarding weight control for patients taking atypical antipsychotics. Methods. Candidate clinical trials were identified through searching the Cochrane Central Register of Controlled Trials, PubMed, and PsycINFO. Fourteen randomized clinical trials were included for systematic review and meta-analysis from 132 potential trials. The Comprehensive Meta-Analysis version 2 was used for meta-analysis. Results. Difference in means and significances from meta-analyses regarding weight control by adjunctive treatments showed that topiramate, aripiprazole, or sibutramine was more effective than metformin or reboxetine. Psychiatric evaluations did not show statistically significant changes between treatment groups and placebo groups except topiramate adjunctive treatments. Adverse effects regarding adjunctive therapies were tolerable and showed statistically no significances compared to control groups. Conclusion. Though having several reports related to exacerbation of psychiatric symptoms, topiramate and aripiprazole are more efficacious than other medications in regard to weight reduction and less burden of critical adverse effects as well as being beneficial for clinical improvement.

    Dengue is a major global public health problem affecting Latin America and Mexico Prevention and control measures, focusing on epidemiological surveillance and vector control, have been partially effective and costly, thus, the development of a vaccine against dengue has created great expectations among health authorities and scientific communities worldwide. The CYD-TDV dengue vaccine produced by Sanofi-Pasteur is the only dengue vaccine evaluated in phase 3 controlled clinical trials. Notwithstanding the significant contribution to the development of a vaccine against dengue, the three phase 3 clinical studies of CYD-TDV and the meta-analysis of the long-term follow up of those studies, have provided evidence that this vaccine exhibited partial vaccine efficacy to protect against virologically confirmed dengue and lead to four considerations: a) adequate vaccine efficacy against dengue virus (DENV) infections 3 and 4, less vaccine efficacy against DENV 1 and no protection against infection by DENV 2; b) decreased vaccine efficacy in dengue seronegative individuals at the beginning of the vaccination; c) 83% and 90% protection against hospitalizations and severe forms of dengue, respectively, at 25 months follow-up; and d) increased hospitalization for dengue in the vaccinated group, in children under nine years of age at the time of vaccination, detected since the third year of follow-up. The benefit of the CYD-TDV vaccine can be summarized in the protection against infection by DENV 3 and 4, as well as protection for hospitalizations and severe cases in people over nine years, who have had previous dengue infection, working mainly as a booster. In this review we identified elements on efficacy and safety of this vaccine that must be taken into account in the licensing process and potential inclusion in the national vaccination program of Mexico. The available scientific evidence on the CYD-TDV vaccine shows merits, but also leads to relevant questions that

    Objective As there is currently no clear recommendation for third-line chemotherapy for smal cel lung cancer (SCLC), its ef icacy is unknown. To date, there have rarely been reports of Chinese patients with SCLC who received third-line chemotherapy. Therefore, we investigated the ef icacy, safety, and prognostic factors of Chinese patients with SCLC treated with third-line chemotherapy. Methods A retrospective analysis of patients with SCLC who received third-line chemotherapy was per-formed. Results Between 2007 and 2013, 82 patients [62 men (75.6%), 20 women (24.4%); median age at the time of diagnosis, 55 years] received third-line chemotherapy at our center. Of these patients, 44 had lim-ited-stage disease and 38 had extensive-stage disease. On third-line chemotherapy, 55 (67.1%) patients had an Eastern Cooperative Oncology Group performance status (ECOG PS) of 0–1, objective response rate of 15.9%, and median overal survival after third-line chemotherapy (OS-3) and median progres-sion-free survival after third-line chemotherapy (PFS-3) of 5.6 months and 3.0 months, respectively. On univariate analysis, PFS-3 was significantly related with ECOG PS (P = 0.005), response to second-line chemotherapy (P = 0.002), response to third-line chemotherapy (P Conclusion Few patients with SCLC receive third-line chemotherapy. Our findings suggest that patients with an ECOG PS 0–1 and PFS-2 for >3 months wil be benefit from third-line chemotherapy, which should be actively of ered to them.

    The present systematic review was conducted to assess the efficacy and safety of apixaban versus other anticoagulants, for the prevention of venous thromboembolism (VTE) following total hip replacement (THR) and total knee replacement (TKR) surgery. Electronic databases were interrogated to identify relevant randomized controlled trials. A series of direct/indirect comparisons and a network meta-analysis were conducted. Indirect comparisons found that the odds ratio of "all VTE and all-cause death" were significantly higher for dabigatran than for apixaban in patients with THR (odds ratio [OR], 2.51; 95% confidence interval [CI], 1.50-4.21) and TKR (OR, 1.72; 95% CI, 1.22-2.42). Rivaroxaban showed similar efficacy to apixaban in patients with THR and TKR (OR, 0.69; 95% CI, 0.38-1.25 and OR, 0.83; 95% CI, 0.57-1.19, respectively). No significant differences were observed in bleeding outcomes between treatments. The novel anticoagulants apixaban, rivaroxaban, and dabigatran demonstrated similar or improved efficacy and similar safety compared with current therapies in this indication.

  15. Efficacy and tolerability of rizatriptan 10 mg compared with sumatriptan 100 mg: an evidence-based analysis.

    Göbel, Hartmut

    2010-04-01

    Acute migraine attacks have a strong impact on quality of life and require immediate therapeutic intervention to achieve rapid pain relief. The introduction of triptans into the market in 1993 has increased the therapeutic options in migraine patients considerably. The seven currently available triptans show many similar characteristics but there are also some clinically relevant pharmacological differences. Rizatriptan 10 mg has demonstrated, in a head-to-head study, higher response rates and a more rapid onset of action than sumatriptan 100 mg, together with a favorable tolerability profile. Meta-analyses of double-blind placebo-controlled studies confirmed the superior efficacy of rizatriptan. Owing to the limited efficacy of sumatriptan, a more effective triptan treatment is needed in the majority of patients with acute migraine attacks.

  19. Systematic review and meta-analysis of the clinical efficacy and adverse effects of Chinese herbal decoction for the treatment of gout.

    Liang Zhou

    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.

  20. Does Alendronate reduce the risk of fracture in men? A meta-analysis incorporating prior knowledge of anti-fracture efficacy in women

    2005-07-01

    Full Text Available Abstract Background Alendronate has been found to reduce the risk of fractures in postmenopausal women as demonstrated in multiple randomized controlled trials enrolling thousands of women. Yet there is a paucity of such randomized controlled trials in osteoporotic men. Our objective was to systematically review the anti-fracture efficacy of alendronate in men with low bone mass or with a history of prevalent fracture(s and incorporate prior knowledge of alendronate efficacy in women in the analysis. Methods We examined randomized controlled trials in men comparing the anti-fracture efficacy of alendronate to placebo or calcium or vitamin D, or any combination of these. Studies of men with secondary causes of osteoporosis other than hypogonadism were excluded. We searched the following electronic databases (without language restrictions for potentially relevant citations: Medline, Medline in Process (1966-May 24/2004, and Embase (1996–2004. We also contacted the manufacturer of the drug in search of other relevant trials. Two reviewers independently identified two trials (including 375 men, which met all inclusion criteria. Data were abstracted by one reviewer and checked by another. Results of the male trials were pooled using Bayesian random effects models, incorporating prior information of anti-fracture efficacy from meta-analyses of women. Results The odds ratios of incident fractures in men (with 95% credibility intervals with alendronate (10 mg daily were: vertebral fractures, 0.44 (0.23, 0.83 and non-vertebral fractures, 0.60 (0.29, 1.44. Conclusion In conclusion, alendronate decreases the risk of vertebral fractures in men at risk. There is currently insufficient evidence of a statistically significant reduction of non-vertebral fractures, but the paucity of trials in men limit the statistical power to detect such an effect.

    2015-12-01

    Full Text Available Objective:To compare efficacy and safety of primaquine regimens currently used to prevent relapses by P. vivax.Methods:A systematic review was carried out to identify clinical trials evaluating efficacy and safety to prevent malaria recurrences by P. vivax of primaquine regimen 0.5 mg / kg / day for 7 or 14 days compared to standard regimen of 0.25 mg/kg/day for 14 days. Efficacy of primaquine according to cumulative incidence of recurrences after 28 days was determined. The overall relative risk with fixed-effects meta-analysis was estimated.Results:For the regimen 0.5 mg/kg/day/7 days were identified 7 studies, which showed an incidence of recurrence between 0% and 20% with follow-up 60-210 days; only 4 studies comparing with the standard regimen 0.25 mg/kg/day/14 days and no difference in recurrences between both regimens (RR= 0.977, 95% CI= 0.670 to 1.423 were found. 3 clinical trials using regimen 0.5 mg/kg/day/14 days with an incidence of recurrences between 1.8% and 18.0% during 330-365 days were identified; only one study comparing with the standard regimen (RR= 0.846, 95% CI= 0.484 to 1.477. High risk of bias and differences in handling of included studies were found.Conclusion:Available evidence is insufficient to determine whether currently PQ regimens used as alternative rather than standard treatment have better efficacy and safety in preventing relapse of P. vivax. Clinical trials are required to guide changes in treatment regimen of malaria vivax.

  2. News Portrayal of Cancer: Content Analysis of Threat and Efficacy by Cancer Type and Comparison with Incidence and Mortality in Korea

    2016-01-01

    How the news media cover cancer may have profound significance for cancer prevention and control; however, little is known about the actual content of cancer news coverage in Korea. This research thus aimed to examine news portrayal of specific cancer types with respect to threat and efficacy, and to investigate whether news portrayal corresponds to actual cancer statistics. A content analysis of 1,138 cancer news stories was conducted, using a representative sample from 23 news outlets (television, newspapers, and other news media) in Korea over a 5-year period from 2008 to 2012. Cancer incidence and mortality rates were obtained from the Korean Statistical Information Service. Results suggest that threat was most prominent in news stories on pancreatic cancer (with 87% of the articles containing threat information with specific details), followed by liver (80%) and lung cancers (70%), and least in stomach cancer (41%). Efficacy information with details was conveyed most often in articles on colorectal (54%), skin (54%), and liver (50%) cancers, and least in thyroid cancer (17%). In terms of discrepancies between news portrayal and actual statistics, the threat of pancreatic and liver cancers was overreported, whereas the threat of stomach and prostate cancers was underreported. Efficacy information regarding cervical and colorectal cancers was overrepresented in the news relative to cancer statistics; efficacy of lung and thyroid cancers was underreported. Findings provide important implications for medical professionals to understand news information about particular cancers as a basis for public (mis)perception, and to communicate effectively about cancer risk with the public and patients.

    2015-05-01

    Identification of predictors of treatment response in patients with major depressive disorder (MDD) may facilitate improved disease management. Data were pooled from two 6-week, double-blind, placebo-controlled studies of extended-release quetiapine (quetiapine XR; 150 or 300 mg/day) as adjunct to ongoing antidepressant therapy. Effects of psychiatric history and baseline demographic and disease characteristics on efficacy outcomes (Week 6 Montgomery Åsberg Depression Rating Scale [MADRS] total score reduction) were evaluated in population subgroups (quetiapine XR both doses pooled, n = 616; placebo, n = 303). Baseline Clinical Global Impressions-Severity (CGI-S) score and previous depressive episodes on Week 6 MADRS total score change, and baseline MADRS individual item scores on Week 6 change in CGI-Improvement score, were also evaluated. No major differences between responders and non-responders to quetiapine XR were observed for patient characteristics or demographic and disease characteristics. No suggestion of a predictive association was found between baseline CGI-S score, number of depressive episodes, and baseline MADRS item scores and efficacy outcomes. These analyses showed no major differences between responders and non-responders, and no predictive association between the parameters assessed and efficacy outcomes for adjunct quetiapine XR in patients with MDD and an inadequate response to prior antidepressant therapy.

  4. Efficacy of deferoxamine in animal models of intracerebral hemorrhage: a systematic review and stratified meta-analysis.

    Han-Jin Cui

    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.

  5. Does Insight Affect the Efficacy of Antipsychotics in Acute Mania?: An Individual Patient Data Regression Meta-Analysis.

    Welten, Carlijn C M; Koeter, Maarten W J; Wohlfarth, Tamar D; Storosum, Jitschak G; van den Brink, Wim; Gispen-de Wied, Christine C; Leufkens, Hubert G M; Denys, Damiaan A J P

    2016-02-01

    Patients having an acute manic episode of bipolar disorder often lack insight into their condition. Because little is known about the possible effect of insight on treatment efficacy, we examined whether insight at the start of treatment affects the efficacy of antipsychotic treatment in patients with acute mania. We used individual patient data from 7 randomized, double-blind, placebo-controlled registration studies of 4 antipsychotics in patients with acute mania (N = 1904). Insight was measured with item 11 of the Young Mania Rating Scale (YMRS) at baseline and study endpoint 3 weeks later. Treatment outcome was defined by (a) mean change score, (b) response defined as 50% or more improvement on YMRS, and (c) remission defined as YMRS score less than 8 at study endpoint. We used multilevel mixed effect linear (or logistic) regression analyses of individual patient data to assess the interaction between baseline insight and treatment outcomes. At treatment initiation, 1207 (63.5%) patients had impaired or no insight into their condition. Level of insight significantly modified the efficacy of treatment by mean change score (P = 0.039), response rate (P = 0.033), and remission rate (P = 0.043), with greater improvement in patients with more impaired insight. We therefore recommend that patients experiencing acute mania should be treated immediately and not be delayed until patients regain insight.

    Full Text Available To evaluate the clinical efficacy and safety of leflunomide as a new immunosuppressive medicine in lupus nephritis (LN through a meta-analysis.A systematic review evaluating the efficacy and safety of leflunomide compared with cyclophosphamide in adult patients with LN was performed. Data from relevant randomized controlled trials (RCTs performed before December 2014 was collected from several databases (PubMed, Embase, Cochrane Library, CNKI and CBM. No language restrictions were applied. Efficacy outcomes included overall remission, SLE Disease Activity Index (SLEDAI score, 24-hour proteinuria and serum creatinine. Safety data were analyzed. The effects of treatment on these outcomes were summarized as relative risks (RRs with 95% confidence intervals (CIs and mean differences were pooled using a fixed or random effects model.Eleven RCTs with Jadad score of 3 or greater were identified and included a total of 254 patients. Cyclophosphamide was served as the control drug in all trials. The SLEDAI score, urine protein level and serum creatinine decreased significantly following leflunomide treatment (P0.05. Additionally, patients receiving leflunomide treatment showed favorable renal function profiles, especially regarding the 24-hour proteinuria (mean difference: -0.58, 95%CI: -0.78~-0.37, P<0.01 and serum creatinine (mean difference: -0.20, 95%CI: -0.39~-0.01, P<0.05. In the safety comparison, leflunomide was safer than cyclophosphamide regarding adverse drug reactions (ADRs, including liver damage (RR = 0.53, 95%CI: 0.33~0.87, P<0.05, alopecia (RR = 0.38, 95%CI: 0.17~0.85, P<0.05, leukopenia (RR = 0.25, 95%CI: 0.08~0.77, P<0.05 and infection (RR = 0.54, 95%CI: 0.32~0.92, P<0.05, without increased risk of gastrointestinal reaction, rash or herpes zoster infection.Leflunomide is a promising therapy for LN treatment, primarily because of the comparable efficacy and favorable safety profile determined by this meta-analysis of RCTs.

  7. Efficacy and safety of dihydroartemisinin-piperaquine for treatment of Plasmodium vivax malaria in endemic countries: meta-analysis of randomized controlled studies.

    Cho Naing

    Full Text Available BACKGROUND: This study aimed to synthesize available evidence on the efficacy of dihydroartemisinin-piperaquine (DHP in treating uncomplicated Plasmodium vivax malaria in people living in endemic countries. METHODOLOGY AND PRINCIPAL FINDINGS: This is a meta-analysis of randomized controlled trials (RCT. We searched relevant studies in electronic databases up to May 2013. RCTs comparing efficacy of (DHP with other artemisinin-based combination therapy (ACT, non-ACT or placebo were selected. The primary endpoint was efficacy expressed as PCR-corrected parasitological failure. Efficacy was pooled by hazard ratio (HR and 95% CI, if studies reported time-to-event outcomes by the Kaplan-Meier method or data available for calculation of HR Nine RCTs with 14 datasets were included in the quantitative analysis. Overall, most of the studies were of high quality. Only a few studies compared with the same antimalarial drugs and reported the outcomes of the same follow-up duration, which created some difficulties in pooling of outcome data. We found the superiority of DHP over chloroquine (CQ (at day > 42-63, HR:2.33, 95% CI:1.86-2.93, I (2: 0% or artemether-lumefentrine (AL (at day 42, HR:2.07, 95% CI:1.38-3.09, I (2: 39%. On the basis of GRADE criteria, further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate. DISCUSSION/CONCLUSION: Findings document that DHP is more efficacious than CQ and AL in treating uncomplicated P. vivax malaria. The better safety profile of DHP and the once-daily dosage improves adherence, and its fixed co-formulation ensures that both drugs (dihydroartemisinin and piperaquine are taken together. However, DHP is not active against the hypnozoite stage of P. vivax. DHP has the potential to become an alternative antimalarial drug for the treatment uncomplicated P. vivax malaria. This should be substantiated by future RCTs with other ACTs. Additional work is

  8. Microsurgical versus endovascular interventions for blood-blister aneurysms of the internal carotid artery: systematic review of literature and meta-analysis on safety and efficacy.

    Shah, Sumedh S; Gersey, Zachary C; Nuh, Mohamed; Ghonim, Hesham T; Elhammady, Mohamed Samy; Peterson, Eric C

    2017-02-17

    OBJECTIVE Blood-blister aneurysms (BBAs) of the internal carotid artery (ICA) have a poor natural history associated with high morbidity and mortality. Currently, both surgical and endovascular techniques are employed to treat BBAs; thus, the authors sought to perform a meta-analysis to compare the efficacy and safety of these approaches. METHODS A literature search of PubMed, MEDLINE, and Google Scholar online databases was performed to include pertinent English-language studies from 2005 to 2015 that discussed the efficacy and safety of either surgical or endovascular therapies to treat BBAs. RESULTS Thirty-six papers describing 256 patients with BBAs treated endovascularly (122 procedures) or surgically (139 procedures) were examined for data related to therapeutic efficacy and safety. Pooled analysis of 9 papers demonstrated immediate and late (mean 20.9 months) aneurysm occlusion rates of 88.9% (95% CI 77.6%-94.8%) and 88.4% (95% CI 76.7%-94.6%), respectively, in surgically treated patients. Pooled analysis of 12 papers revealed immediate and late aneurysm obliteration rates of 63.9% (95% CI 52.3%-74.1%) and 75.9% (95% CI 65.9%-83.7%), respectively, in endovascularly treated aneurysms. Procedure-related complications and overall poor neurological outcomes were slightly greater in the surgically treated cases than in the endovascularly treated cases (27.8% [95% CI 19.6%-37.8%] vs 26.2% [95% CI 18.4%-35.8%]), indicating that endovascular therapy may provide better outcomes. CONCLUSIONS Blood-blister aneurysms are rare, challenging lesions with a poor prognosis. Although surgical management potentially offers superior aneurysm obliteration rates immediately after treatment and at the long-term follow-up, endovascular therapy may have a better safety profile and provide better functional outcomes than surgery. A registry of patients treated for BBAs may be warranted to better document the natural course of the disease as well as treatment outcomes.

    Although atypical antipsychotics are on the rise, traditional treatment of psychotic (or delusional) depression mostly includes the addition of classical antipsychotics to antidepressants. As there are only few data supporting this approach compared with antidepressant monotherapy, and almost no data comparing it with antidepressants of the latest generation, we conducted a retrospective chart analysis and a prospective, randomized open study on the efficacy and tolerability of nefazodone monotherapy versus combined treatment with amitriptyline and haloperidol in psychotic depression. The results suggest that the addition of classical antipsychotics should be reserved for those with very severe psychotic symptoms, but may not be needed in milder forms.

    Background: The aim of this study was to compare the clinical efficacy of coronally advanced flap (CAF) alone and in combination with autologous platelet rich fibrin membrane (PRF) in Miller's class I and II gingival recessions. Materials and Method: Thirty isolated Miller class I or II sites in 26 subjects were randomly divided into test (15 sites- CAF+PRF) and control (15 sites- CAF alone). Parameters probing pocket depth (PPD), Recession depth (RD), Clinical attachment loss (CAL), Keratinised tissue width (KTW) and Gingival tissue thickness (GTH) were evaluated at baseline, 3 months and 6 months postoperatively. Data was subjected to statistical analysis. P< 0.05 was considered statistically significant. Results: Mean percentage root coverage was 91.00±19.98% and 86.60±23.83% for test and control group respectively. Difference between the groups in all parameters at baseline, 3 months and 6 months was non significant. Complete root coverage was obtained in 12 (80%) and 11 (73.3%) subjects in test and control group respectively. The difference was found to be non-significant. Both groups showed significant differences in all parameters at 3 and 6 months respectively except difference in gingival tissue thickness which was non-significant in control group at 3 months. Conclusion: Combination of PRF to CAF procedure did not provide any added advantage in term of recession coverage in Miller class I and II recessions. Long term trials with more sample size are needed to validate these findings. PMID:26097347

  11. Corrigendum to: “Publication bias and time-trend bias in meta-analysis of bicycle helmet efficacy: a re-analysis of Attewell, Glase and McFadden, 2001” [Accid. Anal. Prev. 43 (2011) 1245–1251].

    This paper is a corrigendum to the previously published paper: “Publication bias and time-trend bias in meta-analysis of bicycle helmet efficacy: A re-analysis of Attewell, Glase and McFadden, 2001” [Accid. Anal. Prev. (2011) 1245–1251]. This corrigendum was prepared to correct errors in data and analysis in the previously published paper. Like the previously published paper, this paper confirms that the meta-analysis of bicycle helmet efficacy reported by Attewell, Glase and McFadden (Accident Analysis and Prevention, 2001, 345–352) was influenced by publication bias and time-trend bias that was not controlled for. As a result, the analysis reported inflated estimates of the effects of bicycle helmets. This paper presents a re-analysis of the study. The re-analysis included: (1) Ensuring the inclusion of all published studies by means of continuity corrections of estimates of effect relying on zero counts; (2) detecting and adjusting for publication bias by means of the trim-and-fill method; (3) detecting and trying to account for a time-trend bias in estimates of the effects of bicycle helmets; (4) updating the study by including recently published studies evaluating the effects of bicycle helmets. The re-analysis shows smaller safety benefits associated with the use of bicycle helmets than the original study.

    Objective The aim of this meta-analysis and systematic review is to evaluate the safety and efficacy of Chinese herbal medicine (CHM) for chronic prostatitis (CP) associated with damp-heat and blood-stasis syndromes. Methods An electronic search of 13 databases up to May 2016 was screened to identify randomized controlled trials comparing the safety and efficacy of CHM for the treatment of CP associated with damp-heat and blood-stasis syndromes. Studies reporting on effective rates, adverse events, National Institutes of Health chronic prostatitis symptom index (NIH-CPSI) scores, and symptom index of Chinese medicine for chronic prostatitis (SI-CM) scores as outcomes were included in the analysis. Data were analyzed by fixed- or random-effect models using the Review Manager software. Results Thirteen articles with the modified Jadad score ≥4 were identified. It was found that CHM was superior to placebo in increasing the efficacy (odds ratio: 6.72, 95% confidence interval [CI]: 2.78–9.48, P<0.00001) and reducing the SI-CM scores (standardized mean difference: −1.08, 95% CI: −1.35 to −0.81, P<0.00001). Oral CHMs were significantly more effective than placebo at reducing NIH-CPSI scores, with a mean difference of −1.39 (95% CI: −1.87 to −0.92, P<0.00001). Nevertheless, no significant differences were found between Prostant and placebo (standardized mean difference: −0.23, 95% CI: −0.46 to 0.01, P=0.06). The frequency of adverse events associated with oral CHM was similar to that associated with placebo (risk ratio: 1.36, 95% CI: 0.72–2.55, P=0.34) and less than that associated with Prostant (risk ratio: 1.63, 95% CI: 1.14–2.34, P=0.008). Conclusion Our novel analysis demonstrates that CHM ranks highest in terms of improvement of CP associated with damp-heat and blood-stasis syndromes. While Prostant showed some efficacy in this disorder, it was associated with a smaller reduction in NIH-CPSI scores. In conclusion, CHM monotherapy is safe and

Therefore, we performed this meta-analysis to comprehensively and systematically assess the efficacy of ketamine for treating patients with MDD. Method: Randomized, double-blind, placebo-controlled studies on ketamine versus placebo for treating MDD were searched up to April 2016 in medical databases (PubMed, CCTR, Web of Science, Embase, CBM-disc, and CNKI. Three treatment time points (24 and 72 h, and day 7 were chosen. Response and remission rates were the main outcomes. The random effects model was used. An intention-to-treat analysis was conducted. Results: Nine high-quality studies that included 368 patients were selected to compare the efficacy of ketamine to placebo. The therapeutic effects of ketamine at 24 and 72 h, and day 7 were found to be significantly better than placebo. Response and remission rates in the ketamine group at 24 and 72 h, and day 7 were 52.2% and 20.6%; 47.9% and 23.8%; and 39.8% and 26.2%, respectively. No significant heterogeneity existed, and the Egger’s test showed no publication bias. Conclusion: These results indicated that ketamine could yield a good efficacy in the rapid treatment of MDD. Future large-scale clinical studies are needed to confirm our results and investigate the mid- and long-term efficacy of ketamine in treating MDD. Keywords: major depressive disorder

  15. First efficacy results of capecitabine with anthracycline- and taxane-based adjuvant therapy in high-risk early breast cancer: a meta-analysis.

    Yiwei Jiang

    Full Text Available BACKGROUND: Capecitabine is effective and indicated for the salvage treatment of metastatic breast cancer. Therefore, it is essential to evaluate the efficacy of capecitabine in the adjuvant setting. There have been two large randomized studies to determine whether patients with high-risk early breast cancer benefit from the addition of capecitabine to standard chemotherapy, but they have yielded inconsistent results. We first undertook a meta-analysis to evaluate the efficacy of the addition of capecitabine over standard treatment. METHODS: PubMed, EBSCO, Web of Science, conference proceedings and key trials were searched from 1998 to 2011. The hazard ratio (HR was used to evaluate the efficacy of a taxane-anthracycline regimen and a taxane-anthracycline-capecitabine regimen in early breast cancer. All of the data from each study use either fixed-effects or random-effects by Stata. FINDINGS: We found significant improvement in the additional capecitabine arm versus control in disease-free survival (DFS (HR = 0.83, 95% CI: 0.71-0.98, P = 0.027, overall survival (OS (HR = 0.71, 95% CI: 0.57-0.88, P = 0.002, distant recurrence (HR = 0.79, 95% CI: 0.66-0.94, P = 0.008 and the death from breast cancer only (HR = 0.65, 95% CI: 0.51-0.83, P = 0.001. Meanwhile, the subgroup analysis revealed that capecitabine improved the DFS in triple negative (HR = 0.71, 95% CI: 0.53-0.96, P = 0.028, hormone receptor negative (HR = 0.73, CI: 0.56-0.94, P = 0.017 and HER2 negative (HR = 0.81, CI: 0.67-0.98, P = 0.034 patients. CONCLUSION: Due to the synergistic effect of taxane and capecitabine, taxane-anthracycline-capecitabine regimen may effectively improve the efficacy in the adjuvant setting and may be a novel generation of adjuvant chemotherapy regimen. The results of the current meta-analysis support this hypothesis and indicate that taxane-based regimen with capecitabine may be an effective, convenient

    Full Text Available BACKGROUND: The treatment of impetigo, secondarily infected dermatitis and infected traumatic lesions continue to develop as new generations of drugs are being formulated. Bacteria causing impetigo show growing resistance rates for commonly used antibiotics. Retapamulin being a new drug has been recently approved as topical antibiotic in children and adult. This study aimed to ascertain the efficacy, safety and tolerability of retapamulin as the treatment option for impetigo and other uncomplicated superficial skin infections. METHODS: A search for studies published from 2006-2014 was done in Pubmed, EBSCO, OVID, Science Direct, and Cochrane using the search strategy. The search was limited to studies conducted in human subjects and published in the English language. Randomized controlled trials evaluating the efficacy, safety and tolerability of retapamulin as treatment for impetigo and other uncomplicated superficial skin infections in children and adult were included and extracted independently and the qualities of the studies were appraised using critical appraisal tools. Data analysis was conducted by using RevMan 5. RESULTS: This study has high heterogeneity and found Retapamulin has no statistically significant difference in the clinical success after seven days and follow up among per-protocol-patients, bacteriogical confirmed patients and intention-to-treat patients with impetigo and other secondary infected traumatic lesions compared to other regimens. However, Retapamulin has beneficial effect in the clinical success, well tolerated and safe for children and adults. CONCLUSIONS: Retapamulin is comparably effective and safe as a treatment option for impetigo and other uncomplicated superficial skin infections. KEYWORDS: efficacy, safety, tolerability, retapamulin, impetigo, meta-analysis.

    2015-01-01

    Cognitive behavioural therapy (CBT) is a well-established treatment for obsessive-compulsive disorder (OCD). However, few patients receive CBT, due to factors such as geographic limitations, perceived stigmatization, and lack of CBT services. Technology-delivered cognitive behavioural therapy (T-CBT) could be an effective strategy to improve patients' access to CBT. To date, a meta-analysis on the effectiveness of T-CBT for OCD has not been conducted. This study used meta-analytic techniques to summarize evidence on the efficacy of T-CBT for OCD versus control conditions and therapist-administered CBT. A meta-analysis according to Prisma guidelines was conducted on randomized controlled trials (RCTs) of T-CBT for OCD. Treatment was classified as T-CBT if evidence-based CBT active ingredients for OCD were included (psychoeducation, ERP, and cognitive restructuring), delivered through health technologies (e.g. self-help books, leaflets, and other forms of bibliotherapy) or remote communication technologies (e.g. the Internet, web-cameras, telephones, telephone-interactive voice response systems, and CD-ROMS). Studies using validated outcomes for OCD or depression were included. Eight trials were included (N = 420). Two trials were classified as at high risk of bias. T-CBT seemed to be superior to control conditions on OCD symptom outcomes at post-treatment (d = 0.82, 99% CI = 0.55-1.08, p = 0.001), but not on comorbid depression (d = 0.33, 99% CI = - 0.01-0.67, p = 0.020). Difference in the efficacy on OCD symptoms between T-CBT and therapist-administered CBT was not significant, despite a trend favouring therapist-administered CBT emerged (d = 0.45, 95% CI = 0.03-0.87, p = 0.033). Directions for research are discussed. Further RCTs are warranted to examine the efficacy of T-CBT for OCD.

    2012-05-01

    Scaling root planing (SRP) has been proven efficacious as the traditional treatment approach for chronic periodontitis. However, important limitations such as difficult access in deep pockets, grooves, and furcations have led to the development of new therapeutic strategies. The erbium-doped:yttrium-aluminium-garnet (Er:YAG) laser is one of the most promising laser types for periodontal therapy. Its efficacy in radicular debris removal and root smoothing has been proven in vitro. However, the clinical effectiveness of the Er:YAG laser remains controversial. The aim of the present systematic review was to systemically assess the scientific evidence for the effectiveness of Er:YAG laser compared to SRP in the treatment of chronic periodontitis. Electronic database searches of MEDLINE, Cochrane Controlled Clinical Trial Register, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, CINAHL, Science Direct, ISI Web of Science, and SCOPUS were performed, as well as hand-searching of relevant journals through December 23, 2010. Quality assessment was made according to the CONSORT guidelines. The systematic review was performed according to the QUOROM statement and Cochrane Collaboration recommendations. Meta-analyses of the clinical attachment level gain, probing depth reduction, and changes in gingival recession were performed using weighted mean differences for continuous data with 95% confidence intervals, nested in a random effect model. No statistically significant differences were found in any of the investigated clinical parameters among the five random controlled trials (RCTs) entered into the study, indicating that there was no evidence of effectiveness. However, significant heterogeneity, a high risk of bias in three of the five included studies, and methodological shortcomings indicate that the results should be considered with caution. Future long-term, well-designed RCTs are needed to assess the scientific evidence of Er

    2010-01-01

    Background. Differences in the efficacy of various chemotherapies in patients with estrogen receptor (ER)+ metastatic breast cancer are not well understood. In the present study, we assessed the efficacy of docetaxel in patients with metastatic breast cancer according to ER expression. Methods. The efficacy of docetaxel in terms of the response rate and progression-free survival (PFS) time was analyzed according to ER expression in four randomized trials comparing a docetaxel-based regimen with a nontaxane regimen that included a total of 1,631 patients. The odds ratio for tumor response was estimated with logistic regression and a hazard ratio (HR) for PFS was estimated with Cox proportional hazards models. Findings. ER expression was assessable in 1,037 patients included in these trials (64%). ER was expressed in 601 tumors (58%). Docetaxel was associated with a similarly higher response rate in both patients with ER+ (odds ratio, 2.90; 95% confidence interval [CI], 1.72–4.87) and patients with ER− (odds ratio, 2.55; 95% CI, 1.44–4.51) disease. The lower hazard for disease progression with docetaxel was also similar in ER+ (HR, 0.82; 95% CI, 0.67–1.00) and ER− (HR, 0.86; 95% CI, 0.70–1.07) cancers. The effect of docetaxel was not different in ER+ and ER− disease, in terms of both the response rate and PFS time (interaction test, p = .77 and p = .93). Interpretation. Docetaxel produces a higher response rate and lower risk for disease progression to a statistically similar extent in both patients with ER+ and patients with ER− metastatic breast cancer.

    Background/Aim: To compare the efficacy and tolerance of different proton pump inhibitors (PPIs) in different doses for patients with duodenal ulcers. Materials and Methods: An electronic database was searched to collect all randomized clinical trials (RCTs), and a pairwise and network meta-analysis were performed. Results: A total of 24 RCTs involving 6188 patients were included. The network meta-analysis showed that there were no significant differences for the 4-week healing rate of duodenal ulcer treated with different PPI regimens except pantoprazle 40 mg/d versus lansoprazole 15 mg/d [Relative risk (RR) = 3.57; 95% confidence interval (CI) = 1.36–10.31)] and lansoprazole 30 mg/d versus lansoprazole 15 mg/d (RR = 2.45; 95% CI = 1.01–6.14). In comparison with H2 receptor antagonists (H2 RA), pantoprazole 40 mg/d and lansoprazole 30 mg/d significantly increase the healing rate (RR = 2.96; 95% CI = 1.78–5.14 and RR = 2.04; 95% CI = 1.13–3.53, respectively). There was no significant difference for the rate of adverse events between different regimens, including H2 RA for a duration of 4-week of follow up. Conclusion: There was no significant difference for the efficacy and tolerance between the ordinary doses of different PPIs with the exception of lansoprazle 15 mg/d. PMID:28139495

    Background Ixazomib is the first oral, small molecule proteasome inhibitor to reach phase 3 trials. The current analysis characterized the exposure-safety and exposure-efficacy relationships of ixazomib in patients with relapsed/refractory multiple myeloma (MM) with a purpose of recommending an approach to ixazomib dosing for maintenance therapy. Methods Logistic regression was used to investigate relationships between ixazomib plasma exposure (area under the curve/day; derived from individual apparent clearance values from a published population pharmacokinetic analysis) and safety/efficacy outcomes (hematologic [grade ≥ 3 vs ≤ 2] or non-hematologic [grade ≥ 2 vs ≤ 1] adverse events [AEs], and clinical benefit [≥stable disease vs progressive disease]) using phase 1 data in relapsed/refractory MM (NCT00963820; N = 44). Results Significant relationships to ixazomib exposure were observed for five AEs (neutropenia, thrombocytopenia, rash, fatigue, and diarrhea) and clinical benefit (p phase 3 maintenance trial will initiate ixazomib at a once-weekly dose of 3 mg, increasing to 4 mg if acceptable tolerability after 4 cycles, to provide maximum clinical benefit balanced with adequate tolerability.

    Background Whether olanzapine/fluoxetine combination (OFC) is superior to olanzapine or fluoxetine monotherapy in patients with treatment-resistant depression (TRD) remains controversial. Thus, we conducted this meta-analysis of randomized controlled trials (RCTs) to compare the efficacy and safety of OFC with olanzapine or fluoxetine monotherapy for patients with TRD. Materials and methods RCTs published in PubMed, Embase, Web of Science, and the ClinicalTrials.gov registry were systematically reviewed to assess the efficacy and safety of OFC. Outcomes included mean changes from baseline in Montgomery–Asberg Depression Rating Scale (MADRS), Clinical Global Impression-Severity (CGI-S), Hamilton Rating Scale for Anxiety (HAM-A), Brief Psychiatric Rating Scale (BPRS) scores, response rate, remission rate, and adverse events. Results were expressed with weighted mean difference (WMD) with 95% confidence intervals (CIs) and risk ratio (RR) with 95% CIs. Results A total of five RCTs with 3,020 patients met the inclusion criteria and were included in this meta-analysis. Compared with olanzapine or fluoxetine monotherapy, OFC was associated with greater changes from baseline in MADRS (WMD =−3.37, 95% CI: −4.76, −1.99; Pfluoxetine monotherapy in the treatment of patients with TRD. Our results provided supporting evidence for the use of OFC in TRD. However, considering the limitations in this study, more large-scale, well-designed RCTs are needed to confirm these findings.

    Full Text Available Fibromyalgia is a major public health problem affecting an estimated 200 to 400 million people worldwide. The purpose of this study was to use the meta-analytic approach to determine the efficacy and effectiveness of randomized controlled exercise intervention trials (aerobic, strength training, or both on tender points (TPs in adults with fibromyalgia. Using random effects models and 95% confidence intervals (CI, a statistically significant reduction in TPs was observed based on per-protocol analyses (8 studies representing 322 participants but not intention-to-treat analyses (5 studies representing 338 participants (per-protocol, , −0.68, 95% CI, −1.16, −0.20; intention-to-treat, , −0.24, 95% CI, −0.62, 0.15. Changes were equivalent to relative reductions of 10.9% and 6.9%, respectively, for per-protocol and intention-to-treat analyses. It was concluded that exercise is efficacious for reducing TPs in women with FM. However, a need exists for additional well-designed and reported studies on this topic.

Methods Systematic review with meta-analysis of efficacy within 1–4 weeks and at follow up at 1–12 weeks after the end of treament. Results 36 randomised placebo-controlled trials (RCTs were identified with 2434 patients where 1391 patients received active treatment. 33 trials satisfied three or more out of five methodological criteria (Jadad scale. The patient sample had a mean age of 65.1 years and mean baseline pain of 62.9 mm on a 100 mm visual analogue scale (VAS. Within 4 weeks of the commencement of treatment manual acupuncture, static magnets and ultrasound therapies did not offer statistically significant short-term pain relief over placebo. Pulsed electromagnetic fields offered a small reduction in pain of 6.9 mm [95% CI: 2.2 to 11.6] (n = 487. Transcutaneous electrical nerve stimulation (TENS, including interferential currents, electro-acupuncture (EA and low level laser therapy (LLLT offered clinically relevant pain relieving effects of 18.8 mm [95% CI: 9.6 to 28.1] (n = 414, 21.9 mm [95% CI: 17.3 to 26.5] (n = 73 and 17.7 mm [95% CI: 8.1 to 27.3] (n = 343 on VAS respectively versus placebo control. In a subgroup analysis of trials with assumed optimal doses, short-term efficacy increased to 22.2 mm [95% CI: 18.1 to 26.3] for TENS, and 24.2 mm [95% CI: 17.3 to 31.3] for LLLT on VAS. Follow-up data up to 12 weeks were sparse, but positive effects seemed to persist for at least 4 weeks after the course of LLLT, EA and TENS treatment was stopped. Conclusion TENS, EA and LLLT administered with optimal doses in an intensive 2–4 week treatment regimen, seem to offer clinically relevant short-term pain relief for OAK.

    Full Text Available Yuji Oba, Nazir A Lone University of Missouri, School of Medicine, Division of Pulmonary, Critical Care and Environmental Medicine, Columbia, MO, USA Background: A combination therapy with inhaled corticosteroid (ICS and a long-acting beta agonist (LABA is recommended in severe chronic obstructive pulmonary disease (COPD patients experiencing frequent exacerbations. Currently, there are five ICS/LABA combination products available on the market. The purpose of this study was to systematically review the efficacy of various ICS/LABA combinations with a network meta-analysis. Methods: Several databases and manufacturer's websites were searched for relevant clinical trials. Randomized control trials, at least 12 weeks duration, comparing an ICS/LABA combination with active control or placebo were included. Moderate and severe exacerbations were chosen as the outcome assessment criteria. The primary analyses were conducted with a Bayesian Markov chain Monte Carlo method. Results: Most of the ICS/LABA combinations reduced moderate-to-severe exacerbations as compared with placebo and LABA, but none of them reduced severe exacerbations. However, many studies excluded patients receiving long-term oxygen therapy. Moderate-dose ICS was as effective as high-dose ICS in reducing exacerbations when combined with LABA. Conclusion: ICS/LABA combinations had a class effect with regard to the prevention of COPD exacerbations. Moderate-dose ICS/LABA combination therapy would be sufficient for COPD patients when indicated. The efficacy of ICS/LABA combination therapy appeared modest and had no impact in reducing severe exacerbations. Further studies are needed to evaluate the efficacy of ICS/LABA combination therapy in severely affected COPD patients requiring long-term oxygen therapy. Keywords: combination therapy

    2016-01-01

    Abstract Background: Nonsmall cell lung cancer (NSCLC)-patients treated with standard chemotherapy experienced progression rapidly. A novel therapy based on programed death 1 (PD-1)/programed death ligand 1 (PD-L1) inhibitors showed an increasing potential in several malignancies including advanced NSCLC. Objectives: This article is a meta-analysis aiming to systematically evaluate the efficacy and safety profiles of PD-1/PD-L1 agents in patients with NSCLC. Data sources: Data were collected from eligible studies searched from PubMed, ScienceDirect, and Web of Science. Synthesis methods: Pooled hazard ratio (HR) for overall survival (OS) and progression-free survival (PFS) was estimated to assess the efficacy of PD-1/PD-L1 inhibitors versus docetaxel, pooled odds ratio (OR) was calculated for objective response rate (ORR). The overall frequency was estimated for 1-year OS, 1-year progression-free survival, and ORR. A subgroup analysis among NSCLC patients tested with different epidermal growth factor receptor (EGFR) status was also performed to figure out the relationship between EGFR status and efficacy of PD-1/PD-L1 therapies. OR for occurrence of any grade and grade 3 to 5 treatment-related adverse effect was calculated for evaluating the safety of PD-1/PD-L1 therapies. Results: Nine studies were included in this analysis. The pooled HRs for OS and PFS were 0.68 (95% confidence interval [CI] 0.61–0.75) and 0.83 (95% CI 0.75–0.91), respectively, the pooled OR for ORR was 1.83 (95% CI 1.41–2.36), indicating a significant improvement in OS, PFS, and ORR. In the results of subgroup analysis, the HR for OS in NSCLC patients was 1.05 (95% CI 0.69–1.59) in patients with mutant EGFR and 0.66 (95% CI 0.57–0.77) in patients with wild-type EGFR status. OR for occurrence was 0.36 (95% CI 0.28–0.46) in any grade treatment-related adverse effect and 0.18 (95% CI 0.14–0.22) in grade 3 to 5 treatment-related adverse effect, suggesting a superior safety profile of

    2013-01-01

    The systemic model of crime has received considerable empirical attention from criminologists; yet, an often-neglected component of the theoretical framework is the role of social institutions as a source of both formal and informal social control. Accordingly, the current study builds on recent research that considers the importance of institutional strength for the reduction of criminal behavior; in particular, the authors assess the impact of social-structural characteristics on the treatment program integrity (i.e., institutional efficacy) of 38 halfway house programs in Ohio. The authors' results indicate that communities suffering from concentrated resource deprivation have a more difficult time creating and maintaining strong institutions of public social control. The implications for criminological theory and correctional policy are discussed.

  15. Comparative analysis of copper and zinc based agrichemical biocide products: materials characteristics, phytotoxicity and in vitro antimicrobial efficacy

    Full Text Available In the past few decades, copper based biocides have been extensively used in food crop protection including citrus, small fruits and in all garden vegetable production facilities. Continuous and rampant use of copper based biocides over decades has led to accumulation of this metal in the soil and the surrounding ecosystem. Toxic levels of copper and its derivatives in both the soil and in the run off pose serious environmental and public health concerns. Alternatives to copper are in great need for the agriculture industry to produce food crops with minimal environmental risks. A combination of copper and zinc metal containing biocide such as Nordox 30/30 or an improved version of zinc-only containing biocide would be a good alternative to copper-only products if the efficacy can be maintained. As of yet there is no published literature on the comparative study of the materials characteristics and phyto-compatibility properties of copper and zinc-based commercial products that would allow us to evaluate the advantages and disadvantages of both versions of pesticides. In this report, we compared copper hydroxide and zinc oxide based commercially available biocides along with suitable control materials to assess their efficacy as biocides. We present a detailed material characterization of the biocides including morphological studies involving electron microscopy, molecular structure studies involving X-ray diffraction, phytotoxicity studies in model plant (tomato and antimicrobial studies involving surrogate plant pathogens (Xanthomonas alfalfae subsp. citrumelonis, Pseudomonas syringae pv. syringae and Clavibacter michiganensis subsp. michiganensis. Zinc based compounds were found to possess comparable to superior antimicrobial properties while exhibiting significantly lower phytotoxicity when compared to copper based products thus suggesting their potential as an alternative.

    Background: Probiotic therapies with different strains demonstrated some beneficial effects, although some studies did not show any significant effects. This study assessed systematically the current knowledge on the effect of probiotic bacteria on duration of acute rotavirus diarrhea in children compared with control. Methods: The PubMed, Cochrane Controlled Trial Register (CCTR) and Ovid (Wolters Kluwer Health) were searched between 1980 to June 15, 2013. Randomized controlled trials including the administration of probiotics for treatment of rotavirus diarrhea in infants and children were reviewed. Results: A total number of 1244 articles were found through the aforementioned search. 203 articles were selected after the first screening of title and abstract. The intervention group included subjects who received probiotic strains and dosage in any conditions. Placebo or any similar vehicle without probiotic was used in the controlled trials. Finally, 14 articles were selected. The outcomes from each study were considered in the duration of diarrhea. Statistical analyses were performed with Stata software. The pooled estimate of efficacy of probiotics in prevention or treatment of disease yielded in all studies a mean difference of 0.41 (CI 95%: -0.56 to –0.25; p<0.001). The pooled estimate of efficacy of lactobacillus rhamnosus GG and other probiotics significantly reduced the duration of diarrhea. Among trials, the overall reduction of LGG was 0.47 (CI 95%: -0.80 to -0.14; P= 0.020). Conclusion: In conclusion, probiotics exert positive effect in reducing the duration of acute rotavirus diarrhea compared with control. PMID:26644891

  17. Efficacy of Second Generation Direct-Acting Antiviral Agents for Treatment Naive Hepatitis C Genotype 1: A Systematic Review and Network Meta-Analysis.

    Thanthima Suwanthawornkul

    Full Text Available The treatment of hepatitis C (HCV infections has significantly changed in the past few years due to the introduction of direct-acting antiviral agents (DAAs. DAAs could improve the sustained virological response compared to pegylated interferon with ribavirin (PR. However, there has been no evidence from randomized controlled trials (RCTs that directly compare the efficacy among the different regimens of DAAs.Therefore, we performed a systematic review and network meta-analysis aiming to compare the treatment efficacy between different DAA regimens for treatment naïve HCV genotype 1.Medline and Scopus were searched up to 25th May 2015. RCTs investigating the efficacy of second generation DAA regimens for treatment naïve HCV genotype 1 were eligible for the review. Due to the lower efficacy and more side effects of first generation DAAs, this review included only second generation DAAs approved by the US or EU Food and Drug Administration, that comprised of simeprevir (SMV, sofosbuvir (SOF, daclatasvir (DCV, ledipasvir (LDV, and paritaprevir/ritonavir/ombitasvir plus dasabuvir (PrOD. Primary outcomes were sustained virological response at weeks 12 (SVR12 and 24 (SVR24 after the end of treatment and adverse drug events (i.e. serious adverse events, anemia, and fatigue. Efficacy of all treatment regimens were compared by applying a multivariate random effect meta-analysis. Incidence rates of SVR12 and SVR24, and adverse drug events of each treatment regimen were pooled using 'pmeta' command in STATA program.Overall, 869 studies were reviewed and 16 studies were eligible for this study. Compared with the PR regimen, SOF plus PR, SMV plus PR, and DVC plus PR regimens yielded significantly higher probability of having SVR24 with pooled risk ratios (RR of 1.98 (95% CI 1.24, 3.14, 1.46 (95% CI: 1.22, 1.75, and 1.68 (95% CI: 1.14, 2.46, respectively.

Study quality was assessed based on likelihood of bias in selection, attrition, detection and performance.Improvement in best-corrected visual acuity (BCVA measured as the proportion of patients gaining ≥10 letters on the Early Treatment Diabetic Retinopathy Study scale. The outcome was chosen following acceptance by NICE of a Markov model with 10-letter health states in the assessment of ranibizumab for DME.Bayesian network meta-analyses with fixed and random effects adjusted for differences in baseline BCVA or central retinal thickness.The analysis included 1,978 patients from eight RCTs. The random effects model adjusting for baseline BCVA was the best model based on total residual. The efficacy of ranibizumab was numerically, but not statistically, superior to aflibercept (odds ratio [OR] 1.59; 95% credible interval [CrI], 0.61-5.37. Ranibizumab and aflibercept were statistically superior to laser monotherapy with ORs of 5.50 (2.73-13.16 and 3.45 (1.62-6.84 respectively. The probability that ranibizumab is the most efficacious treatment was 73% compared with 14% for aflibercept, 12% for ranibizumab plus laser, and 0% for laser.Three of the eight RCTs included are not yet published. The models did not adjust for all potential effect modifiers.Ranibizumab was non-significantly superior to aflibercept and both anti-VEGF therapies had statistically superior efficacy to laser.

    Peptide receptor radionuclide therapy (PRRT) is an effective method for treating neuroendocrine tumors (NETs). It is limited, however, in the prediction of individual tumor response and the precise and early identification of changes in tumor size. Currently, response prediction is based on somatostatin receptor expression and efficacy by morphological imaging and/or chromogranin A (CgA) measurement. The aim of this study was to assess the accuracy of circulating NET transcripts as a measure of PRRT efficacy, and moreover to identify prognostic gene clusters in pretreatment blood that could be interpolated with relevant clinical features in order to define a biological index for the tumor and a predictive quotient for PRRT efficacy. NET patients (n = 54), M: F 37:17, median age 66, bronchial: n = 13, GEP-NET: n = 35, CUP: n = 6 were treated with {sup 177}Lu-based-PRRT (cumulative activity: 6.5-27.8 GBq, median 18.5). At baseline: 47/54 low-grade (G1/G2; bronchial typical/atypical), 31/49 {sup 18}FDG positive and 39/54 progressive. Disease status was assessed by RECIST1.1. Transcripts were measured by real-time quantitative reverse transcription PCR (qRT-PCR) and multianalyte algorithmic analysis (NETest); CgA by enzyme-linked immunosorbent assay (ELISA). Gene cluster (GC) derivations: regulatory network, protein:protein interactome analyses. Statistical analyses: chi-square, non-parametric measurements, multiple regression, receiver operating characteristic and Kaplan-Meier survival. The disease control rate was 72 %. Median PFS was not achieved (follow-up: 1-33 months, median: 16). Only grading was associated with response (p < 0.01). At baseline, 94 % of patients were NETest-positive, while CgA was elevated in 59 %. NETest accurately (89 %, χ{sup 2} = 27.4; p = 1.2 x 10{sup -7}) correlated with treatment response, while CgA was 24 % accurate. Gene cluster expression (growth-factor signalome and metabolome) had an AUC of 0.74 ± 0.08 (z-statistic = 2.92, p < 0

    2014-02-01

    Full Text Available The present study examined students' statistics-related self-efficacy, as measured with the current statistics self-efficacy (CSSE inventory developed by Finney and Schraw (2003. Structural equation modeling was used to check the confirmatory factor analysis of the one-dimensional factor of CSSE. Once confirmed, this factor was used to test whether a significant link to prior mathematics experiences exists. Additionally a new post-structural equation modeling (SEM application was employed to compute error-free latent variable score for CSSE in an effort to examine the ancillary effects of gender, age, ethnicity, department, degree level, hours completed, expected course grade, number of college-level math classes, current GPA on students' CSSE scores. Results support the one-dimensional construct and as expected, the model demonstrated a significant link between CSSE scores and prior mathematics experiences to CSSE. Additionally the students' department, expected grade, and number of prior math classes were found to have a significant effect on student's CSSE scores.

  1. Modeling contextual effects using individual-level data and without aggregation: an illustration of multilevel factor analysis (MLFA) with collective efficacy.

    Population health scientists increasingly study how contextual-level attributes affect individual health. A major challenge in this domain relates to measurement, i.e., how best to measure and create variables that capture characteristics of individuals and their embedded contexts. This paper presents an illustration of multilevel factor analysis (MLFA), an analytic method that enables researchers to model contextual effects using individual-level data without using derived variables. MLFA uses the shared variance in sets of observed items among individuals within the same context to estimate a measurement model for latent constructs; it does this by decomposing the total sample variance-covariance matrix into within-group (e.g., individual-level) and between-group (e.g., contextual-level) matrices and simultaneously modeling distinct latent factor structures at each level. We illustrate the MLFA method using items capturing collective efficacy, which were self-reported by 2,599 adults in 65 census tracts from the Los Angeles Family and Neighborhood Survey (LAFANS). MLFA identified two latent factors at the individual level and one factor at the neighborhood level. Indicators of collective efficacy performed differently at each level. The ability of MLFA to identify different latent factor structures at each level underscores the utility of this analytic tool to model and identify attributes of contexts relevant to health.

    Spinal muscular atrophy (SMA) is an autosomal recessive disease of variable severity caused by mutations in the SMN1 gene. Deficiency of the ubiquitous SMN function results in spinal cord α-motor neuron degeneration and proximal muscle weakness. Gene replacement therapy with recombinant adeno-associated viral (AAV) vectors showed therapeutic efficacy in several animal models of SMA. Here, we report a study aimed at analyzing the efficacy and biodistribution of a serotype-9, self-complementary AAV vector expressing a codon-optimized human SMN1 coding sequence (coSMN1) under the control of the constitutive phosphoglycerate kinase (PGK) promoter in neonatal SMNΔ7 mice, a severe animal model of the disease. We administered the scAAV9-coSMN1 vector in the intracerebroventricular (ICV) space in a dose-escalating mode, and analyzed survival, vector biodistribution and SMN protein expression in the spinal cord and peripheral tissues. All treated mice showed a significant, dose-dependent rescue of lifespan and growth with a median survival of 346 days. Additional administration of vector by an intravenous route (ICV+IV) did not improve survival, and vector biodistribution analysis 90 days postinjection indicated that diffusion from the cerebrospinal fluid to the periphery was sufficient to rescue the SMA phenotype. These results support the preclinical development of SMN1 gene therapy by CSF vector delivery.

    Objective. To evaluate the efficacy and safety of the total glucosides of peony (TGP) and leflunomide (LEF) for the treatment of rheumatoid arthritis (RA). Methods. Randomized controlled trials (RCTs) on the efficacy and safety of the combination of TGP and LEF versus LEF alone for the treatment of RA were retrieved by searching PubMed, EMBASE, Cochrane Library, the China National Knowledge Infrastructure database, and Wanfang database. Results. Eight RCTs including 643 RA patients were included in the present meta-analysis. The quality of included studies was poor. The levels of ESR (P < 0.0001), CRP (P < 0.0001), and RF (P < 0.0001) in RA patients who received the combination of TGP and LEF were significantly lower than RA patients who received LEF therapy alone. The pooled results suggest that the combination of TGP and LEF caused less abnormal liver function than LEF alone (P = 0.02). No significant difference in the gastrointestinal discomfort was identified between the combination of TGP and LEF and LEF alone groups (P = 0.18). Conclusion. The combination of TGP and LEF in treatment of RA presented the characteristics of notably decreasing the levels of laboratory indexes and higher safety in terms of liver function. However, this conclusion should be further investigated based on a larger sample size.

    Full Text Available Background and aim: A simeprevir (SMV-based regimen has shown promising results in treating chronic hepatitis C virus (HCV infection. This meta-analysis aimed to assess the efficacy and safety of simeprevir for treating HCV genotype 1 infection. Methods: MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were searched, along with the reference lists of retrieved articles. The meta-analysis only included randomized controlled trials (RCTs that compared the efficacy and safety of addition of SMV to peginterferon (PegIFN and ribavirin (RBV (triple regimen with PegIFN/RBV alone (dual regimen in treating chronic HCV genotype 1 infection. Results: A total of seven RCTs involving 2,301 patients were included. The triple regimen had a higher pooled sustained virologic response (SVR rate [odds ratio (OR = 4.57; 95% confidence interval (CI: 3.34-6.27; p < 0.001] and lower pooled relapse rate [relative risk (RR = 0.41; 95% CI: 0.33-0.50; p < 0.001] than the dual regimen had. The pooled incidence of adverse events (AEs was comparable between the two regimens (RR = 1.01; 95% CI: 0.99-1.03; p = 0.339, whereas the incidence of serious AEs in the triple regimen was lower (RR = 0.7; 95% CI: 0.50-0.98; p < 0.05. Conclusions: The meta-analysis demonstrates that the addition of SMV to pegIFN and RBV is effective and well-tolerated in treating chronic HCV genotype 1 infection, with a low incidence of AEs.

We aimed to evaluate the efficacy and safety of S-1-based therapy versus capecitabine -based therapy in gastrointestinal cancers. METHODS: Eligible studies were identified from Pubmed, EMBASE. Additionally, abstracts presented at American Society of Clinical Oncology (ASCO conferences held between 2000 and 2013 were searched to identify relevant clinical trials. The outcome included overall survival (OS, progression-free survival (PFS, overall response rate (ORR, disease control rate (DCR and advent events. RESULTS: A total of 6 studies (4 RCTs and 2 retrospective analysis studies containing 790 participants were included in this meta-analysis, including 401 patients in the S-1-based group and 389 patients in the capecitabine-based group. Results of our meta-analysis indicated that S-1-based and capecitabine-based regimens showed very similar efficacy in terms of PFS (HR 0.92, 95% CI 0.78-1.09, P = 0.360, OS (HR 1.01, 95% CI 0.84-1.21, P = 0.949, ORR (HR 1.04, 95% CI 0.87-1.25, P = 0.683 and DCR (HR 1.02, 95% CI 0.94-1.10, P = 0.639. There was also no significant difference in toxicity between regimens other than mild more hand-foot syndrome in capecitabine-based regimens. CONCLUSION: Both the S-1-based and capecitabine-based regimens are equally active and well tolerated, and have the potential of backbone chemotherapy regimen in further studies of gastrointestinal cancers.

    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. Titration of pregabalin to the

    Stefan Vegter

    Full Text Available BACKGROUND: Several treatments are available for actinic keratosis (AK on the face and scalp. Most treatment modalities were compared to placebo and therefore little is known on their relative efficacy. OBJECTIVES: To compare the different treatments for mild to moderate AK on the face and scalp available in clinical practice in Europe. METHODS: A network meta-analysis (NMA was performed on the outcome "complete patient clearance". Ten treatment modalities were included: two 5-aminolaevulinic acid photodynamic therapies (ALA-PDT, applied as gel (BF-200 ALA or patch; methyl-aminolevulinate photodynamic therapy (MAL-PDT; three modalities with imiquimod (IMI, applied as a 4-week or 16-week course with 5% imiquimod, or a 2-3 week course with 3.75% imiquimod; cryotherapy; diclofenac 3% in 2.5% hyaluronic acid; 0.5% 5-fluorouracil (5-FU; and ingenol mebutate (IMB. The only data available for 5% 5-FU was from one small study and was determined to be too limited to be reliably included in the analysis. For BF-200 ALA and MAL-PDT, data from illumination with narrow-band lights were selected as these are typically used in clinical practice. The NMA was performed with a random-effects Bayesian model. RESULTS: 25 trials on 5,562 patients were included in the NMA. All active treatments were significantly better than placebo. BF-200 ALA showed the highest efficacy compared to placebo to achieve total patient clearance. BF-200 ALA had the highest probability to be the best treatment and the highest SUCRA score (64.8% and 92.1%, followed by IMI 5% 4 weeks (10.1% and 74.2% and 5-FU 0.5% (7.2% and 66.8%. CONCLUSIONS: This NMA showed that BF-200 ALA, using narrow-band lights, was the most efficacious treatment for mild to moderate AK on the face and scalp. This analysis is relevant for clinical decision making and health technology assessment, assisting the improved management of AK.

Methods: In this prospective, observational, noninterventional study, pregabalin (Lyrica® was prescribed following usual clinical practice. Compared with baseline, the primary study end points after 3 months of observation were changes in 1 the average level of pain during the past week, 2 the worst level of pain during the past week, and 3 the least level of pain during the past week. The Wilcoxon signed-rank test was used to perform paired analyses, and a multivariate regression analysis investigated factors driving change in pain. Results: A total of 86 of the 128 patients included were regarded as efficacy evaluable (those completing 3 months of pregabalin treatment. Patients (59 years were long-time sufferers of peripheral NeP, and 38% of them had comorbidities. The majority had previously been treated with tricyclic antidepressants or gabapentin. The average dose of pregabalin was 81.5 mg/d at baseline and 240 mg/d after 3 months. A clinically and statistically significant improvement of 2.2 points in the average level of pain intensity was found after 3 months. The higher the pain intensity at baseline, the higher was the reduction of the pain score. Positive results were also found for pain-related sleep interference, patients’ global impression of change, quality of life, and work and productivity impairment. Twenty-one patients reported 28 adverse events. Conclusion: This real-life study indicates that for some

Studies reporting on effective rates, adverse events, National Institutes of Health chronic prostatitis symptom index (NIH-CPSI scores, and symptom index of Chinese medicine for chronic prostatitis (SI-CM scores as outcomes were included in the analysis. Data were analyzed by fixed- or random-effect models using the Review Manager software.Results: Thirteen articles with the modified Jadad score ≥4 were identified. It was found that CHM was superior to placebo in increasing the efficacy (odds ratio: 6.72, 95% confidence interval [CI]: 2.78–9.48, P<0.00001 and reducing the SI-CM scores (standardized mean difference: -1.08, 95% CI: -1.35 to -0.81, P<0.00001. Oral CHMs were significantly more effective than placebo at reducing NIH-CPSI scores, with a mean difference of -1.39 (95% CI: -1.87 to -0.92, P<0.00001. Nevertheless, no significant differences were found between Prostant and placebo (standardized mean difference: -0.23, 95% CI: -0.46 to 0.01, P=0.06. The frequency of adverse events associated with oral CHM was similar to that associated with placebo (risk ratio: 1.36, 95% CI: 0.72–2.55, P=0.34 and less than that

    2010-04-01

    Cross-sectional studies show that self-efficacy (SE) serves as a partial mediator of the effect that perceptions of workplace environment have on self-reported workplace physical activity (PA). To further explore the role SE plays in the relationship between perceptions of the workplace environment and workplace PA, cross-sectional mediation analyses were performed on adult employees at baseline (n = 897), 6 months (n = 616), and 12 months (n = 612); a longitudinal time-sequence was incorporated into the mediation model; and correlates of residual change version of the mediation were tested. The R (2) ranged from .05 to .08 for the three cross-sectional analyses, .03 for the longitudinal analyses, and from .02 to .03 for the residual analyses. The results from the residual change model analyses supported those of the cross-sectional and longitudinal analyses, suggesting the relationship between perceived workplace environment and PA was partially mediated by SE. Future research should include similar studies with different population groups and in different settings.

  12. The Efficacy of Trastuzumab in Animal Models of Breast Cancer: A Systematic Review and Meta-Analysis.

    Jiarong Chen

    Full Text Available Breast cancer is the most frequent cancers and is the second leading cause of cancer death among women. Trastuzumab is an effective treatment, the first monoclonal antibody directed against the human epidermal growth factor receptor 2 (HER2. To inform the development of other effective treatments we report summary estimates of efficacy of trastuzumab on survival and tumour volume in animal models of breast cancer.We searched PubMed and EMBASE systematically to identify publications testing trastuzumab in animal models of breast cancer. Data describing tumour volume, median survival and animal features were extracted and we assessed quality using a 12-item checklist. We analysed the impact of study design and quality and evidence for publication bias.We included data from 83 studies reporting 169 experiments using 2076 mice. Trastuzumab treatment caused a substantial reduction in tumour growth, with tumours in treated animals growing to 32.6% of the volume of tumours in control animals (95%CI 27.8%-38.2%. Median survival was prolonged by a factor of 1.45 (1.30-1.62. Many study design and quality features accounted for between-study heterogeneity and we found evidence suggesting publication bias.We have found trastuzumab to be effective in animal breast cancer models across a range of experimental circumstances. However the presence of publication bias and a low prevalence of measures to reduce bias provide a focus for future improvements in preclinical breast cancer research.

    At many central synapses, the presynaptic bouton and postsynaptic density are structurally correlated. However, it is unknown whether this correlation extends to the functional properties of the synapses. To investigate this, we made recordings from synaptically coupled pairs of pyramidal neurons in rat visual cortex. The mean peak amplitude of EPSPs recorded from pairs of L2/3 neurons ranged between 40 microV and 2.9 mV. EPSP rise times were consistent with the majority of the synapses being located on basal dendrites; this was confirmed by full anatomical reconstructions of a subset of connected pairs. Over a third of the connections could be described using a quantal model that assumed simple binomial statistics. Release probability (P(r)) and quantal size (Q), as measured at the somatic recording site, showed considerable heterogeneity between connections. However, across the population of connections, values of P(r) and Q for individual connections were positively correlated with one another. This correlation also held for inputs to layer 5 pyramidal neurons from both layer 2/3 and neighboring layer 5 pyramidal neurons, suggesting that during development of cortical connections presynaptic and postsynaptic strengths are dependently scaled. For 2/3 to 2/3 connections, mean EPSP amplitude was correlated with both Q and P(r) values but uncorrelated with N, the number of functional release sites mediating the connection. The efficacy of a cortical connection is thus set by coordinated presynaptic and postsynaptic strength.

    Full Text Available Abstract Background The objective of this study was to evaluate the efficacy of atomoxetine, a new and highly selective inhibitor of the norepinephrine transporter, in reducing symptoms of attention-deficit/hyperactivity disorder (ADHD among adults by using drug-placebo response curve methods. Methods We analyzed data from two double-blind, placebo-controlled, parallel design studies of adult patients (Study I, N = 280; Study II, N = 256 with DSM-IV-defined ADHD who were recruited by referral and advertising. Subjects were randomized to 10 weeks of treatment with atomoxetine or placebo, and were assessed with the Conners Adult ADHD Rating Scales and the Clinical Global Impression of ADHD Severity scale before and after treatment. Results Those treated with atomoxetine were more likely to show a reduction in ADHD symptoms than those receiving placebo. Across all measures, the likelihood that an atomoxetine-treated subject improved to a greater extent than a placebo-treated subject was approximately 0.60. Furthermore, atomoxetine prevented worsening of most symptom classes. Conclusion From these findings, we conclude that atomoxetine is an effective treatment for ADHD among adults when evaluated using several criteria.

Methods: Eighty-seven patients (48 female, 39 male; mean age, 58.2; range, 19-91 who underwent 106 PN procedures performed by using USG and fluoroscopy combination between July 2011 and May 2015 were retrospectively analyzed. The technical success was considered if nephrostomy catheter was placed within renal pelvis and functioned spontaneously. All patients received preprocedural prophylactic antibiotic and preprocedural coagulation parameters and platelet count were tested in all patients routinely. The procedural complications are classified as major, minor and catheter-related. The technical success rates and complication rates of the PN procedure were calculated. Results: PN was performed for benign causes in 47 patients (54% and for malignant causes in 40 patients (46%. A total of 106 nephrostomies were performed in 101 kidneys (95.1% with dilated systems and in 5 kidneys (4.9% with non-dilated systems. The technical success rate of PN was 98.1% (104/106 PN procedures. Major complication was not observed in any patients. Transient hematuria as a minor complication was seen in 11 patients (12.6%. Catheter dislodgement occurred in 11 patients (12.6%. Conclusion: The PN performed by using combined USG and fluoroscopy is effective and reliable procedure in urinary decompression and diversion with high success and low complication rates.

    Full Text Available Background. Diverticulum, one of the long-term sequelae of cesarean section, can cause abnormal uterine bleeding and increase the risk of uterine scar rupture. In this study, we aimed to evaluate the efficacy of combined laparoscopic and hysteroscopic repair, a newly occurring method, treating post-cesarean section uterine scar diverticulum. Methods. Data relating to 40 patients with post-cesarean section uterine diverticulum who underwent combined laparoscopic and hysteroscopic repair were retrospectively analyzed. Preoperative clinical manifestations, size of uterine defects, thickness of the lower uterine segment (LUS, and duration of menstruation were compared with follow-up findings at 1, 3, and 6 months after surgery. Results. The average preoperative length and width of uterine diverticula and thickness of the lower uterine segment were recorded and analyzed. The average durations of menstruations at 1, 3, and 6 months after surgery were significantly shorter than the preoperative one (p<0.05, respectively. At 6 months after surgery, the overall success improvement rate of surgery was 90% (36/40. Three patients (3/40 = 7.5% developed partial improvement, and 1/40 (2.5% was lost to follow-up. Conclusions. Our findings showed that combined treatment with laparoscopy and hysteroscopy was an effective method for the repair of post-cesarean section uterine diverticulum.

    Full Text Available Routine use of antifibrinolytic agents in spine surgery is still an issue of debate.To gather scientific evidence for the efficacy and safety of antifibrinolytic agents including aprotinin, tranexamic acid (TXA and epsilon aminocaproic acid (EACA, traditionally known as Amicar in reducing perioperative blood loss and transfusion requirements in scoliosis surgery.We conducted a systematic review and meta-analysis for randomized controlled trials (RCTs, retrospective case-control studies, and retrospective cohort studies on the use of antifibrinolytic agents in scoliosis surgery by searching in the MEDLINE and EMBASE databases and the Cochrane Database of Systematic Reviews and Controlled Trials of papers published from January 1980 through July 2014. Safety of the antifibrinolytic agents was evaluated in all included studies, while efficacy was evaluated in RCTs.Eighteen papers with a total of 1,158 patients were eligible for inclusion in this study. Among them, 8 RCTs with 450 patients were included for evaluation of pharmacologic efficacy (1 RCT was excluded because of a lack of standard deviation data. Mean blood loss was reduced in patients with perioperative use of antifibrinolytic agents by 409.25 ml intraoperatively (95% confidence interval [CI], 196.57-621.94 ml, 250.30 ml postoperatively (95% CI, 35.31-465.30, and 601.40 ml overall (95% CI, 306.64-896.16 ml. The mean volume of blood transfusion was reduced by 474.98 ml (95% CI, 195.30-754.67 ml.

    Full Text Available To perform a systematic review and meta-analysis regarding the efficacy and safety of dipeptidyl peptidase-4 (DDP-4 inhibitors ("gliptins" for the treatment of type 2 diabetes mellitus (T2DM patients with moderate to severe renal impairment.All available randomized-controlled trials (RCTs that assessed the efficacy and safety of DDP-4 inhibitors compared with placebo, no treatment, or active drugs were identified using PubMed, EMBASE, Cochrane CENTRAL, conference abstracts, clinical trials.gov, pharmaceutical company websites, the FDA, and the EMA (up to June 2014. Two independent reviewers extracted the data, and a random-effects model was applied to estimate summary effects.Thirteen reports of ten studies with a total of 1,915 participants were included in the final analysis. Compared with placebo or no treatment, DPP-4 inhibitors reduced HbA1c significantly (-0.52%, 95%CI -0.64 to -0.39 and had no increased risk of hypoglycemia (RR 1.10, 95%CI 0.92 to 1.32 or weight gain. In contrast to glipizide monotherapy, DPP-4 inhibitors showed no difference in HbA1c lowering effect (-0.08%, 95% CI -0.40 to 0.25 but had a lower incidence of hypoglycemia (RR 0.40, 95%CI 0.23 to 0.69. Furthermore, DPP-4 inhibitors were well-tolerated, without any additional mortality and adverse events. However, the quality of evidence was mostly as low, as assessed using the GRADE system for each outcome.DPP-4 inhibitors are effective at lowering HbA1c in T2DM patients with moderate to severe renal impairment. DPP-4 inhibitors also have a potential advantage in lowering the risk of adverse events. Regarding the low quality of the evidence according to GRADE, additional well-designed randomized trials that focus on the safety and efficacy of DPP-4 inhibitors in various CKD stages are needed urgently.

  19. Clinical efficacy and tolerability of praziquantel for intestinal and urinary schistosomiasis-a meta-analysis of comparative and non-comparative clinical trials.

    Julien Zwang

    Full Text Available Extensive use of praziquantel for treatment and control of schistosomiasis requires a comprehensive understanding of efficacy and safety of various doses for different Schistosoma species.A systematic review and meta-analysis of comparative and non-comparative trials of praziquantel at any dose for any Schistosoma species assessed within two months post-treatment. Of 273 studies identified, 55 were eligible (19,499 subjects treated with praziquantel, control treatment or placebo. Most studied were in school-aged children (64%, S. mansoni (58%, and the 40 mg/kg dose (56%; 68% of subjects were in Africa. Efficacy was assessed as cure rate (CR, n=17,017 and egg reduction rate (ERR, n=13,007; safety as adverse events (AE incidence. The WHO-recommended dose of praziquantel 40 mg/kg achieved CRs of 94.7% (95%CI 92.2-98.0 for S. japonicum, 77.1% (68.4-85.1 for S. haematobium, 76.7% (95%CI 71.9-81.2 for S. mansoni, and 63.5% (95%CI 48.2-77.0 for mixed S. haematobium/S. mansoni infections. Using a random-effect meta-analysis regression model, a dose-effect for CR was found up to 40 mg/kg for S. mansoni and 30 mg/kg for S. haematobium. The mean ERR was 95% for S. japonicum, 94.1% for S. haematobium, and 86.3% for S. mansoni. No significant relationship between dose and ERR was detected. Tolerability was assessed in 40 studies (12,435 subjects. On average, 56.9% (95%CI 47.4-67.9 of the subjects receiving praziquantel 40 mg/kg experienced an AE. The incidence of AEs ranged from 2.3% for urticaria to 31.1% for abdominal pain.The large number of subjects allows generalizable conclusions despite the inherent limitations of aggregated-data meta-analyses. The choice of praziquantel dose of 40 mg/kg is justified as a reasonable compromise for all species and ages, although in a proportion of sites efficacy may be lower than expected and age effects could not be fully explored.

Currently, there is a lack of up-to-date and comprehensive evidence on how available ADHD drugs compare and rank in terms of efficacy and tolerability, in children or adolescents as well as in adults. We will conduct a network meta-analysis (NMA), integrating direct and indirect comparisons from randomised controlled trials (RCTs), to rank pharmacological treatments for ADHD according to their efficacy and tolerability profiles. Methods and analysis We will search a broad range of electronic databases, including PubMed, MEDLINE, EMBASE, PsycINFO, ERIC and Web of Science, with no date or language restrictions. We will also search for unpublished studies using international clinical trial registries and contacting relevant drug companies. We will identify and include available parallel-group, cross-over and cluster randomised trials that compare methylphenidate, dexmethylphenidate, amphetamine derivatives (including lisdexamfetamine), atomoxetine, clonidine, guanfacine, bupropion or modafinil (as oral therapy) either with each other or to placebo, in children, adolescents or adults with ADHD. Primary outcomes will be efficacy (indicated by reduction in severity of ADHD core symptoms measured on a standardised scale) and tolerability (the proportion of patients who left a study early due to side effects). Secondary outcomes will be global functioning, acceptability (proportion of patients who left the study early by any cause) and changes in blood pressure and body weight. NMA will be conducted in STATA within a frequentist framework. The quality of RCTs will be evaluated using the Cochrane risk of bias tool, and the quality of the evidence will be assessed using the GRADE approach. Subgroup and sensitivity analyses will be conducted to assess the robustness of the findings. Ethics and

    Background Phacotrabeculectomy can be performed using one-site or two-site incisions.This meta-analysis evaluated the efficacy and tolerability of one-site versus two-site phacotrabecuiectomy in the treatment of patients with coexisting cataract and glaucoma.Methods A comprehensive literature search was performed according to the Cochrane Collaboration methodology toidentify randomized controlled clinical trials comparing one-site with two-site phacotrabeculectomy.Studies meeting our predefined criteria were included in the meta-analysis.Efficacy estimates were measured by weighted mean difference (WMD) for the percentage intraocular pressure (IOP) reduction from baseline to end point, relative risk (RR) for the proportion of patients with a best-corrected visual acuity (BCVA) of 0.5 or better after surgery and complete success rates.Tolerability estimates were measured by RR for adverse events.All of outcomes were reported with 95% confidence interval (95% CI).Data were synthesised by Stata 10.1 for Windows.Results Two-site phacotrabeculectomy was associated with greater reductions in IOP than the one-site procedure (WMD: -5.99, 95% CI: -10.74-1.24, P=0.01).A greater proportion of patients also achieved a BCVA of 0.5 or better (RR:0.91, 95% CI: 0.74-1.12, P=0.36) and the target IOP without anti-glaucoma medication at the study end point (RR: 0.94,95% CI: 0.83-1.07, P=0.34) after two-site than one-site phacotrabeculectomy, but the differences were not significant.There were no significant differences in adverse events between two surgical procedures.Conclusions Two-site phacotrabeculectomy is superior to one-site phacotrabeculectomy in reducing IOP, but other post-operative effects are similar.One-site and two-site phacotrabeculectomies have similar adverse event rates.

    Systematic flow-through column experiments were conducted using sediments and ground water collected from different subsurface localities at the U.S. Department of Energy’s Integrated Field Research Challenge site in Rifle, Colorado. The principal purpose of this study is to gain a better understanding of the interactive effects of groundwater geochemistry, sediment mineralogy, and indigenous bacterial community structures on the efficacy of uranium removal from the groundwater with/without acetate amendment. Overall, we find that the subtle variations in the sediments’ mineralogy, particle size, redox conditions, as well as contents of metal(loid) co-contaminants showed a pronounced effect on the associated bacterial population and composition, which mainly determines the system’s performance with respect to uranium removal. Positive relationship was identified between the abundance of dissimilatory sulfate-reduction genes (i.e., drsA), markers of sulfate-reducing bacteria, and the sediments’ propensity to sequester aqueous uranium. In contrast, no obvious connections were observed between the abundance of common iron-reducing bacteria, e.g., Geobacter spp., and the sediments’ ability to sequester uranium. In the sediments with low bacterial biomass and the absence of sulfate-reducing conditions, abiotic adsorption onto mineral surfaces such as phyllosilicates likely played a relatively major role in the attenuation of aqueous uranium; however, in these scenarios, acetate amendment induced detectable rebounds in the effluent uranium concentrations. The results of this study suggest that reductive immobilization of uranium can be achieved under predominantly sulfate-reducing conditions, and provide insight into the integrated roles of various biogeochemical components in long-term uranium sequestration.

    Background What benefits and toxicities patients acquire from the use of bevacizumab combined with first-line chemotherapy remains controversial.This study was performed to evaluate the efficacy and safety of first-line chemotherapy plus bevacizumab in patients with metastatic colorectal cancer (mCRC).Methods Several databases,including PubMed,Embase,and Cochrane Library,were searched up to April 30,2013.Eligible studies were only randomized,controlled trials (RCTs) with a direct comparison between mCRC patients treated with and without bevacizumab.Overall risk ratio (RR),hazard ratio (HR),odds ratio (OR),and 95% confidence intervals (CO were calculated employing fixed or random-effects models depending on the heterogeneity of the included trials.Results Six RCTs,including 1582 patients in chemotherapy plus bevacizumab group and 1484 patients in chemotherapyalone group,were included.Overall,the addition of bevacizumab to first-line chemotherapy increased overall response rate (ORR) by 4.5%,prolonged both progression-free survival (PFS) and overall survival (OS),and increased the rate of total Grades 3 or 4 adverse events (G3/4AEs) by 6.9%.Significant differences were found in ORR (RR=1.22 (95% CI 1.01-1.46),P=0.03),PFS (HR=0.60 (95% Cl 0.47-0.77),P <0.0001),OS (HR=0.83 (95% Cl 0.70-0.97),P=0.02),and any G3/4AEs (OR=1.56 (95% Cl 1.29-1.89),P <0.00001).Conclusion Bevacizumab is a valuable addition to the current first-line chemotherapy regimens used in patients with mCRC,because of conferring a significant improvement in ORR,PFS,and OS,even though it increased adverse events.

    We reviewed and analyzed safety and efficacy data after mobilization with granulocyte colony-stimulating factor (G-CSF) according to healthy donor's (HDs) age as follows: HDs-1, n = 161), aged 50 to 59 years (HDs-2, n = 62), and ≥60 years or over (HDs-3, n = 23). Two hundred forty-six HDs were evaluated, and their characteristics were well balanced among age groups: most were male, siblings, and HLA matched. According to age group, the median numbers of CD34(+) cells in the peripheral blood for HDs-1, HDs-2, and HDs-3 were, respectively, 44.5, 34.5, and 26 (HDs-1 versus HDs-2, P = .002; HDs-1 versus HDs-3, P = .036; HDs-2 versus HDs-3, P = n.s.) at day 4 and 65.5, 58, and 46 (HDs-1 versus HDs-2, P = .039; HDs-1 versus HDs-3, P = .002; HDs-2 versus HDs-3, P = n.s.) at day 5. With a median apheresis session of 1, the number of CD34(+) cells/kg recipient body weight collected was not significantly different (6.4 in HDs-1, 6.0 in HDs-2, and 5.7 in HDs-3, P = n.s.). Short- and long-term safety did not differ among age groups. Bone pain was reported as the most frequent short-term adverse event (76.5%). After a median follow-up of 7.8 years, the observed rate of solid tumors, hematological malignancies, and cardiovascular and autoimmune events was similar to the expected incidence for these diseases in Western countries. These results show that G-CSF is effective in the mobilization of older HDs. Moreover, our data contribute to the growing body of evidence in support of the long-term safety of G-CSF for allogeneic donor stem cell mobilization also for elderly HDs.

  5. Efficacy of Hospital at Home in Patients with Heart Failure: A Systematic Review and Meta-Analysis.

    Full Text Available Heart failure (HF is the commonest cause of hospitalization in older adults. Compared to routine hospitalization (RH, hospital at home (HaH--substitutive hospital-level care in the patient's home--improves outcomes and reduces costs in patients with general medical conditions. The efficacy of HaH in HF is unknown.We searched MEDLINE, Embase, CINAHL, and CENTRAL, for publications from January 1990 to October 2014. We included prospective studies comparing substitutive models of hospitalization to RH in HF. At least 2 reviewers independently selected studies, abstracted data, and assessed quality. We meta-analyzed results from 3 RCTs (n = 203 and narratively synthesized results from 3 observational studies (n = 329. Study quality was modest. In RCTs, HaH increased time to first readmission (mean difference (MD 14.13 days [95% CI 10.36 to 17.91], and improved health-related quality of life (HrQOL at both, 6 months (standardized MD (SMD -0.31 [-0.45 to -0.18] and 12 months (SMD -0.17 [-0.31 to -0.02]. In RCTs, HaH demonstrated a trend to decreased readmissions (risk ratio (RR 0.68 [0.42 to 1.09], and had no effect on all-cause mortality (RR 0.94 [0.67 to 1.32]. HaH decreased costs of index hospitalization in all RCTs. HaH reduced readmissions and emergency department visits per patient in all 3 observational studies.In the context of a limited number of modest-quality studies, HaH appears to increase time to readmission, reduce index costs, and improve HrQOL among patients requiring hospital-level care for HF. Larger RCTs are necessary to assess the effect of HaH on readmissions, mortality, and long-term costs.

    OBJECTIVE: To examine and compare the safety and efficacy of extended treatment with dabigatran, apixaban, rivaroxaban and warfarin in patients with unprovoked venous thromboembolism. METHODS: PubMed and Embase were searched for randomized clinical trials reporting on the use of direct oral...... in the study. 5 studies were included in the meta-analysis. Results from the meta-analysis showed that the extended use of DOACs and warfarin significantly decreased the risk of recurrent VTE with 83 % when compared placebo. Warfarin (RR: 0.03, CI: 0.00-0.49) and dabigatran (RR: 0.08, CI: 0.03-0.27) showed......-analysis that dabigatran was non-inferior to VKA for the prevention of recurrent VTE (HR: 1.44, CI: 0.78-2.64, p=0.01 for noninferiority) and decreased the risk of NMCRB compared to VKA (RR: 0.58, CI: 0.43-0.77). CONCLUSION: Extended treatment with both warfarin and DOACs are effective in preventing recurrent VTE and does...

    We performed a systematic review and meta-analysis to assess whether selective serotonin reuptake inhibitors (SSRIs) and phosphodiesterase type 5 inhibitors (PDE5-Is) may have an additive therapeutic effect. A literature review was performed to identify all published randomised controlled trials (RCT) that used SSRIs combined with PDE5-Is therapy for the treatment of primary PE. The search included the following databases: EMBASE, MEDLINE and the Cochrane Controlled Trials Register. The reference lists of the retrieved studies were also investigated. Five publications involving a total of 419 patients were used in the analysis, including 5 RCTs that compared PDE5-Is plus SSRIs with SSRIs treating primary PE. Primary efficacy endpoints: IELT (the standardised mean difference (SMD) = 1.07, 95% confidence interval (CI) = 1.00 to 1.14, P < 0.00001) indicated that utilisation of PDE5-Is and SSRIs was more effective than the SSRIs alone for a long time in patients with primary PE. Safety assessments included headache (odds ratio (OR) = 3.16, 95% CI = 1.63 to 6.11, P = 0.0006), and flushing indicated that PDE5-Is plus SSRIs were well tolerated. This meta-analysis indicates that PDE5-Is combined with SSRIs seem to provide significantly better ejaculatory latency time as compared with SSRIs alone in patients with primary PE.

    The aim of the present study was to conduct an updated meta-analysis of relevant randomized controlled trials (RCTs) in order to estimate the effect of folic acid supplementation on endothelial function and the concentration of plasma homocysteine in patients with coronary artery disease (CAD). An extensive search of PubMed was conducted to identify RCTs that compared folic acid with placebo therapy. The mean difference (MD) and 95% confidence interval (CI) were used as a measure of the correlation between folic acid supplementation and endothelial function/plasma homocysteine concentration. Of the 377 patients included in this analysis, 191 patients underwent folic acid supplementation and 186 individuals underwent placebo treatment. Compared with the use of a placebo, folic acid supplementation alone exhibited significant efficacy on increasing flow-mediated dilation (FMD; MD, 57.72 μm; 95% CI, 50.14-65.31; Pfolic acid and placebo groups (P>0.05). Therefore, the meta-analysis indicated that 5 mg folic acid daily supplementation for >4 weeks significantly improved FMD and lowered the concentration of plasma homocysteine in patients with CAD. However, more RCTs are required in order to confirm these observations.

  9. Acceptance and Efficacy of Metacognitive Training (MCT) on Positive Symptoms and Delusions in Patients With Schizophrenia: A Meta-analysis Taking Into Account Important Moderators.

    Eichner, Carolin; Berna, Fabrice

    2016-07-01

    Metacognitive training (MCT) is a new, widely used intervention for psychosis. The present meta-analysis examines the efficacy of MCT in schizophrenia. Fifteen studies comparing effects of MCT on positive symptoms, delusions or acceptance of MCT with a control group were included in this meta-analysis. These studies comprised a total of 408 patients in the MCT condition and 399 in the control condition. The moderating effects of masking of outcome assessment, randomization, incomplete outcome data, use of an active control intervention, and individual vs group MCT were investigated. Possible effects of sensitivity analyses and publication bias were also examined. The results show a significant overall effect of MCT for positive symptoms (g = -0.34, 95% CI [-0.53, -0.15]), delusions (g = -0.41, 95% CI [-0.74, -0.07]) and acceptance of the intervention (g = -0.84, 95% CI [-1.37, -0.31]). Using only studies being at low risk for bias regarding randomization, masking and incomplete outcome data reduced effect sizes for positive symptoms and delusions (g = -0.28, 95% CI [-0.50, -0.06] and g = -0.18, 95% CI [-0.43, 0.06]), respectively. This meta-analysis demonstrates that MCT exerts a small to moderate effect on delusions and positive symptoms and a large effect on acceptance of the intervention. The effect on delusions is reduced, but remains significant when potential biases are considered.

    In chronic myeloid leukemia (CML) patients, 3-month BCR-ABL1 levels have consistently been correlated with further outcomes. Monitoring molecular responses in CML using the GeneXpert (Cepheid) platform has shown an optimal correlation with standardized RQ-PCR (IS) when measuring BCR-ABL1 levels lower than 10%, as it is not accurate for values over 10%. The aim of the present study was to determine the predictive molecular value at three months on different outcome variables using the Xpert BCR-ABL1 MonitorTM assay (Xpert BCR-ABL1). We monitored 125 newly diagnosed consecutive CML patients in the chronic phase (CML-CP) using an automated method: Xpert BCR-ABL1. Only 5% of patients did not achieve an optimal response at 3 months, and the 10% BCR-ABL1 cutoff defined by RQ-PCR (IS) methods was unable to identify significant differences in the probabilities of achieving a complete cytogenetic response (CCyR) (50% vs. 87%, p = 0.1) or a major molecular response (MMR) (60% vs. 80%, p = 0.29) by 12 months. In contrast, a cutoff of 1.5% more accurately identified differences in the probabilities of achieving CCyR (98% vs. 54%, p<0.001) and MMR (88% vs. 56%, p<0.001) by 12 months, as well as probabilities of treatment changes (p = 0.005). Therefore, when using the Xpert BCR-ABL1 assay, a cutoff of 1.5% at 3 months could with high probability identify patients able to achieve an optimal response at 12 months. PMID:28278193

Methods: Trials published between 1990 and 2015 were identified by an electronic search of public databases (Medline, Embase, and Cochrane Library. All clinical studies were independently identified by two authors. Demographic data, treatment regimens, objective response rate (ORR, progression-free survival (PFS, and overall survival (OS were extracted and analyzed using comprehensive meta-analysis software (version 2.0. Results: A total of 2,551 patients with advanced nonsquamous NSCLC from ten trials were included for analysis: 1,565 patients were treated with pemetrexed plus platinum doublet chemotherapy and 986 with platinum plus other first-line chemotherapy. Pooled ORR for pemetrexed plus platinum chemotherapy was 37.8% (95% confidence interval [CI]: 31.7%–44.3%, with median PFS and OS of 5.7 and 16.05 months, respectively. When compared to other platinum-based doublet chemotherapies, the use of pemetrexed plus platinum chemotherapy significantly improved OS (hazard ratio [HR] =0.86, 95% CI: 0.77–0.97, P=0.01 but not PFS (HR =0.90, 95% CI: 0.80–1.01, P=0.084 in advanced nonsquamous NSCLC patients. Conclusion: Pemetrexed plus platinum doublet regimen is an efficacious treatment for advanced nonsquamous NSCLC patients. Our

Although benzodiazepines (BZDs can have adverse effects on respiratory response in COPD patients, these are the most common hypnotics. The aim of this study was to examine by meta-analysis the efficacy and safety of BZD to treat insomnia in COPD patients. Materials and methods: Electronic databases (PubMed, China National Knowledge Infrastructure, Cochrane clinical trials database were searched. Studies were eligible if they compared the effects of BZD versus placebo on insomnia in COPD patients. Two reviewers extracted data independently. Disagreements were resolved by discussion with another reviewer until a consensus was achieved. Data that included objective and subjective sleep evaluation and respiratory function variables were extracted. Data were analyzed by the methods recommended by Review Manager 5.3 software. Results: A total of 233 records were identified through the initial search; of these, five studies were included in the meta-analysis. When BZD was compared with placebo, objective sleep quality was significantly improved, including total sleep time (95% confidence interval [CI] 0.54–1.14, P<0.00001, sleep efficiency (95% CI 0.48–1.16, P<0.00001, sleep latency (95% CI -18.24 to -4.46, P=0.001, and number of arousals/hour of sleep (95% CI -0.72 to -0.07, P=0.02. Otherwise, subjective sleep quality was not improved remarkably. Apart from maximum transcutaneous carbon dioxide pressure increase during sleep (95% CI 0.05–0.28, P=0.006, BZD administration had no effect on respiratory assessment. Conclusion: In this meta-analysis, the results suggested BZDs might be efficient and

    Our objective was to evaluate the safety and efficacy of clomiphene citrate (CC) in infertile and hypoandrogenic men through a retrospective study between September 2013 and May 2014. We identified 47 men between 18 and 55 years placed on 50 mg CC every other day. We evaluated the effect of CC on testosterone after 2 weeks, rates of adverse effects and predictors of CC response. Mean baseline testosterone, bioavailable testosterone and estradiol were 246.8 ng dl(-1), 125.5 ng dl(-1) and 20.8 pg dl(-1), respectively. At 2 weeks, mean testosterone, bioavailable testosterone and estradiol increased to 527.6 ng dl(-1), 281.8 ng dl(-1) and 32.0 pg dl(-1) (all P<0.001). Two patients at 2 weeks and one patient at 3 months had a paradoxical decrease in testosterone. Mean total motile count (TMC) and concentration increased from 59.7 million (s.e.m.: 16.5) and 50.7 millions ml(-1) (s.e.m.: 11.1) at baseline to 90.9 million (s.e.m.: 25.9) and 72.5 millions ml(-1) (s.e.m.: 17.5), respectively, at 3 months, although this was nonsignificant (P=0.09, 0.09). No patient on CC experienced a paradoxical decrease in TMC or sperm concentration. On age-adjusted regression analysis, age, BMI, longitudinal testis axis, baseline follicle-stimulating hormone, LH and estradiol did not correlate with improvement in bioavailable testosterone at 2 weeks. CC improves testosterone and may improve semen parameters, although a small percentage of men may not demonstrate improvement in testosterone.

    2016-01-01

    Background:Peroral endoscopic myotomy(POEM)is a novel minimally invasive endoscopic technique for treatment of esophageal achalasia(EA). It has been demonstrated to be safe and effective in several short-term clinical studies, however,studies focusing on its mid- and long-term outcome are rare. Aims:To investigate the mid-and-long term efficacy of POEM in EA patients. Methods:A retrospective analysis was performed in 41 EA patients who underwent POEM in the Department of Gastroenterology and Hepatology of Nanjing General Hospital of Nanjing Military Region from Jul. 2012 to Dec. 2013. All these patients were followed up periodically for clinical symptoms(Eckardt score),maximum esophageal diameter and lower esophageal sphincter pressure(LESP),and the intra- and post-operative complications and recurrence were recorded. Results:POEM was successfully completed in all 41 EA patients,the mean operative time was(69. 5 ± 20. 6)min(range 35-125 min),and the mean length of hospital stay was 3. 5 days. Compared with the pre-operative data,the post-operative Eckardt score,maximum esophageal diameter and LESP during follow-up(mean 26. 3 months, range 19-36 months)were significantly decreased(P all < 0. 05). Procedure-related complications were seen in 6 patients (14. 6% );the clinical success rate was 95. 1%(39 / 41)and the recurrence rate was 2. 4%(1 / 41). Conclusions:POEM is safe and effective in mid-and-long term follow-up with low recurrence rate. It might become the first-line therapy for EA,and the long-term efficacy and complications need further follow-up study.%背景:经口内镜下肌切开术(POEM)是治疗贲门失弛缓症(EA)新的内镜微创技术,临床研究证实其用于治疗EA 安全、有效,短期疗效肯定,但关于 POEM 治疗 EA 中长期疗效的报道尚少。目的:探讨 POEM 治疗 EA 的中长期疗效。方法:回顾性分析2012年7月—2013年12月于南京军区南京总医院消化内科接受 POEM

    2013-01-01

    Allele Specific Amplification with four primers (External Antisense Primer, External Sense Primer, Internal Nonfragrant Sense Primer, and Internal Fragrant Antisense Primer) and sensory evaluation with leaves and grains were executed to identify aromatic rice genotypes and their F1 individuals derived from different crosses of 2 Malaysian varieties with 4 popular land races and 3 advance lines. Homozygous aromatic (fgr/fgr) F1 individuals demonstrated better aroma scores compared to both heterozygous nonaromatic (FGR/fgr) and homozygous nonaromatic (FGR/FGR) individuals, while, some F1 individuals expressed aroma in both leaf and grain aromatic tests without possessing the fgr allele. Genotypic analysis of F1 individuals for the fgr gene represented homozygous aromatic, heterozygous nonaromatic and homozygous nonaromatic genotypes in the ratio 20:19:3. Genotypic and phenotypic analysis revealed that aroma in F1 individuals was successfully inherited from the parents, but either molecular analysis or sensory evaluation alone could not determine aromatic condition completely. The integration of molecular analysis with sensory methods was observed as rapid and reliable for the screening of aromatic genotypes because molecular analysis could distinguish aromatic homozygous, nonaromatic homozygous and nonaromatic heterozygous individuals, whilst the sensory method facilitated the evaluation of aroma emitted from leaf and grain during flowering to maturity stages.

The efficacy and safety of PRM for primary insomnia in patients aged 55 years and older who are treated with antihypertensive drugs were evaluated.Methods: Post hoc analysis of pooled antihypertensive drug-treated subpopulations from four randomized, double-blind trials of PRM and placebo for 3 weeks (N[PRM] = 195; N[placebo] = 197 or 28 weeks (N[PRM] = 157; N[placebo] = 40. Efficacy measurements included Leeds Sleep Evaluation Questionnaire scores of quality of sleep and alertness and behavioral integrity the following morning after 3 weeks, and sleep latency (daily sleep diary and Clinical Global Impression of Improvement (CGI-I after 6 months of treatment. Safety measures included antihypertensive drug-treated subpopulations from these four and three additional single-blind and open-label PRM studies of up to 1 year (N[PRM] = 650; N[placebo] = 632.Results: Quality of sleep and behavior following wakening improved significantly with PRM compared with placebo (P < 0.0001 and P < 0.0008, respectively. Sleep latency (P = 0.02 and CGI-I (P = 0.0003 also improved significantly. No differences were observed between PRM and placebo groups in vital signs, including daytime blood pressure at baseline and treatment phases. The rate of adverse events normalized per 100 patient-weeks was lower for PRM (3.66 than for placebo (8.53.Conclusions: The findings demonstrate substantive and sustained efficacy of PRM in primary insomnia patients treated with antihypertensive drugs

    Objective:To investigate the visual and refractive outcome of wavefront-guided laser in situ keratomileusis(LASIK) to correct myopic astigmatism.Methods:This prospective study comprised 35 eyes of 28 patients who had a mean preoperative spherical refraction of -4.8 diopters(D)±2.3(SD) and a cylinder of (-1.1±0.9)D. Preoperative and postoperative wavefront analysis was performed with a Tscherning aberrometer. A scanning-spot laser with a 1.0mm spot size and a 200Hz repetition rate was used. The eye-tracking system had a response time of less than 6 milliseconds. The treatment area diameter ranged from 6.0 to 7.0mm with a transition zone of 1.0mm.Results:At 3 months,68.0% of the eyes were within ±0.5D of emmetropia and 93.5% were within ±1.0D. Uncorrected visual acuity was 20/20 or better in 93.5% of eyes. No eye lost more than 1 line of low-contrast,glare,and best spectacle-corrected visual acuity(BSCVA). Supernormal vision(BSCVA of 20/10 or better) was achieved in 16.0% of eyes. The correction of higher-order aberrations(spherical aberration,coma) was insufficient,with an inverse factor of the overall root-mean-square wavefront error of 1.44±0.74. Coma was better corrected than spherical aberration.Conclusion:Wavefront-guided LASIK is a promising technique that offers the potential to correct refractive errors,to improve visual acuity,and to increase the quality of vision,especially under mesopic conditions. Studies that include selective overcorrection of different Zernike components are needed to achieve better correction of the aberrations. Prospective controlled clinical studies must clarify the major benefits of wavefront-guided LASIK.%目的:观察波前像差引导的LASIK手术矫正近视性散光的效果。方法:28例35只眼,平均术前球镜屈光度为(-4.8±2.3)D,柱镜屈光度为(-1.1±0.9)D。手术前和手术后均使用Tscherning像差计测量,分析波前像差。应用1.0mm光斑、频率200Hz的飞点扫描准分

    Full Text Available Objective. To assess alflutop clinical efficacy and safety during long-term course treatment of knee osteoarthritis. Methods. 51 pts with definite knee osteoarthritis of I-III stage according to Kellgren-Lawrence classification were included in an open controlled study. 20 pts received 6 intra-articular injections of alflutop 2 ml with subsequent intramuscular treatment during 3 months. Such courses were repeated 6 months apart for 2 years. 31 pts of control group received nonsteroidal anti-inflammatory drugs (NSAID only. Pain on visual analog scale, Leken functional score, changes of NSAID treatment and radiological picture were used for assessment of efficacy. Clinical examination was performed before and after every treatment course and 3 months after the last course. Results. Every alflutop treatment course provided significant stepwise decrease of pain with improvement of mobility, reduction of NSAID requirement and absence of osteoarthritis radiological progression. Doctor and pts clinical efficacy and safety assessment coincided. Conclusion. Alflutop is an effective drug for knee osteoarthritis treatment. It has anti-inflammatory and probably chondroprotective activity with good safety.

    Full Text Available OBJECTIVE: A meta-analysis was conducted to investigate the efficacy and safety of three main iron chelators, namely, deferoxamine (DFO, deferiprone (DFP and deferasirox (DFX for thalassemia major (TM patients. METHODS: Randomized controlled trials comparing mono-therapy DFO, DFP, DFX and combined DFP with DFO therapy in TM patients from January 1990 to December 2012 were searched and selected. Two independent authors assessed data from extracted randomized trials for efficacy and safety in the measurements of serum ferritin (SF, live iron concentration (LIC, myocardial iron content (MIC, left ventricular ejection fraction (LVEF and adverse events (AEs. RESULTS: Sixteen studies were selected. In the comparison of DFP versus DFO treatment groups, a significant difference was revealed on MIC and LVEF (P=0.01 and P=0.007, respectively but not on SF or LIC level (P=0.65 and P=0.37, respectively. In comparing combined therapy (DFP plus DFO versus DFO, a significant difference was shown on MIC and LVEF measurements (P<0.00001 and P=0.003, respectively, but not on SF or LIC levels (P=0.93 and P=0.62, respectively. Moreover, the combined DFP with DFO treatment had significantly higher risk than DFO treatment (RR 1.46 with 95%CI 1.04 to 2.04. When comparing DFX with DFO, a significant difference was shown on the SF level (P=0.003, and there was no difference between DFX and DFO in safety evaluation (RR 1.53 with 95%CI 0.31 to 7.49. CONCLUSION: Findings indicated that the most effective and safe iron chelators remains to be proven, and further large-scale, long-term studies are needed.

    We conducted this systematic reviews and meta-analysis to investigate the safety and efficacy of ocrelizumab in patients with active rheumatoid arthritis (RA) who exhibited resistance or intolerance to methotrexate or biological therapy. We performed a web-based literature search of PubMed, Google Scholar, EBSCO, Scopus, Embase, and Web of science for studies that compared ocrelizumab plus methotrexate versus methotrexate plus placebo in RA patients. Data were extracted from eligible studies and pooled as risk ratios (RR), using RevMan software. Pooling data from four RCTs (2230 patients) showed that ocrelizumab plus methotrexate were superior to methotrexate plus placebo at 24 weeks in terms of improvement on the American college of rheumatology (ACR20, ACR50, and ACR70) criteria (p < 0.00001), disease activity score 28-ESR (RR = 3.77, 95% CI [2.47, 5.74], p < 0.00001), and Sharp/van der Heijde radiological score (RR = 1.63, 95% CI [1.43, 1.85], p < 0.00001). These effects were consistent among all ocrelizumab doses. The rates of serious adverse events were comparable between the ocrelizumab and placebo containing groups (RR = 1, 95% CI [0.78, 1.28], p = 0.98). However, infusion related reactions were significantly higher in ocrelizumab group (RR = 2.13, 95% CI [1.69, 2.68], p < 0.00001), compared to placebo group. The combination of ocrelizumab plus methotrexate was superior to methotrexate plus placebo on all clinical and radiographic improvement scales. The incidence of adverse events, including serious adverse events, was comparable between both groups. Future trials should investigate the efficacy of ocrelizumab alone and develop strategies to alleviate its related infusion reactions.
