    Full Text Available Abstract Background Prospective, multicenter, randomized, double-masked trials have shown latanoprost instilled once daily to be at least as effective as and generally superior to timolol administered twice daily and to be as effective as other frequently prescribed prostaglandin analogues. This study prospectively assessed the efficacy of latanoprost monotherapy in a large cohort of treatment-naive patients with a broad range of baseline intraocular pressure (IOP levels treated in actual clinical practice settings. Methods This prospective, open-label, multicenter, uncontrolled, phase IV study included treatment-naive ocular hypertension or open-angle glaucoma subjects initiating latanoprost once daily (evening. IOP levels were measured at baseline and after 1 and 3 months. The primary efficacy outcome was mean change in IOP from baseline to month 3. Analyses were stratified by baseline IOP: ≥ 20 and vs ≥ 24 mmHg. Results Efficacy analyses (intent to treat included 572 subjects: 20 to vs -9.2 ± 3.7 mmHg, respectively; -28.0 ± 10.6% vs -34.1 ± 11.9%, respectively. An IOP reduction of ≥ 30% from baseline to month 3 was noted in 48.4% and 65.6% of subjects, respectively (p Conclusions This "real world" study found once-daily latanoprost to be effective and safe in treatment-naive ocular hypertension or open-angle glaucoma patients.

    Background: This double-blind, parallel-group, multicenter, phase-3 study was designed to test the noninferiority of paliperidone palmitate 3-month formulation (PP3M) to the currently marketed 1-month formulation (PP1M) in patients (age 18–70 years) with schizophrenia, previously stabilized on PP1M. Methods: After screening (≤3 weeks) and a 17-week, flexible-dosed, open-label phase (PP1M: day 1 [150mg eq. deltoid], day 8 [100mg eq. deltoid.], weeks 5, 9, and 13 [50, 75, 100, or 150mg eq., deltoid/gluteal]), clinically stable patients were randomized (1:1) to PP3M (fixed-dose, 175, 263, 350, or 525mg eq. deltoid/gluteal) or PP1M (fixed-dose, 50, 75, 100, or 150mg eq. deltoid/gluteal) for a 48-week double-blind phase. Results: Overall, 1016/1429 open-label patients entered the double-blind phase (PP3M: n=504; PP1M: n=512) and 842 completed it (including patients with relapse). PP3M was noninferior to PP1M: relapse rates were similar in both groups (PP3M: n=37, 8%; PP1M: n=45, 9%; difference in relapse-free rate: 1.2% [95% CI:-2.7%; 5.1%]) based on Kaplan-Meier estimates (primary efficacy). Secondary endpoint results (changes from double-blind baseline in positive and negative symptom score total and subscale scores, Clinical Global Impression-Severity, and Personal and Social Performance scores) were consistent with primary endpoint results. No clinically relevant differences were observed in pharmacokinetic exposures between PP3M and PP1M. Both groups had similar tolerability profiles; increased weight was the most common treatment-emergent adverse event (double-blind phase; 21% each). No new safety signals were detected. Conclusion: Taken together, PP3M with its 3-month dosing interval is a unique option for relapse prevention in schizophrenia. PMID:26902950

    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.

    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.

    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.

    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.

    Full Text Available Familial Mediterranean Fever is an autosomal recessive disease. Major symptoms of disease are recurrent fever accompanied by serositis attacks. The disease is usually diagnosed before 20 years of age. Symptoms related to FMF are noted when children become more verbal, usually after 2 years of age. In this case report, the youngest patient with the diagnosis of FMF is presented. She was consulted to pediatric rheumatology for the high acute phase response and fever. It was learned that her mother had recurrent swelling of her ankle joints. Mutation analysis was performed and two homozygous mutations (M694V and R202Q were identified. She was diagnosed as FMF at 3 months of age and colchicine was started. She responded to colchicine. Her uncontrolled acute phase response declined gradually. This case was reported to point out the importance of early remembrance of autoinflammatory diseases even at very early ages especially at endemic countries.

    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.

    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

    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.

    Full Text Available This study explores the emergence of triadic interactions through the example of book sharing. As part of a naturalistic study, 10 infants were visited in their homes from 3-12 months. We report that (1 book sharing as a form of infant-caregiver-object interaction occurred from as early as 3 months. Using qualitative video analysis at a micro-level adapting methodologies from conversation and interaction analysis, we demonstrate that caregivers and infants practiced book sharing in a highly co-ordinated way, with caregivers carving out interaction units and shaping actions into action arcs and infants actively participating and co-ordinating their attention between mother and object from the beginning. We also (2 sketch a developmental trajectory of book sharing over the first year and show that the quality and dynamics of book sharing interactions underwent considerable change as the ecological situation was transformed in parallel with the infants' development of attention and motor skills. Social book sharing interactions reached an early peak at 6 months with the infants becoming more active in the coordination of attention between caregiver and book. From 7-9 months, the infants shifted their interest largely to solitary object exploration, in parallel with newly emerging postural and object manipulation skills, disrupting the social coordination and the cultural frame of book sharing. In the period from 9-12 months, social book interactions resurfaced, as infants began to effectively integrate object actions within the socially shared activity. In conclusion, to fully understand the development and qualities of triadic cultural activities such as book sharing, we need to look especially at the hitherto overlooked early period from 4-6 months, and investigate how shared spaces of meaning and action are structured together in and through interaction, creating the substrate for continuing cooperation and cultural learning.

    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.

    Several devices and medications have been used to address poststroke spasticity. Yet, spasticity's impact on outcomes remains controversial. Using data from a cohort of 460 ischemic stroke patients, we previously published a validated multivariable regression model for predicting 3-month modified Rankin Score (mRS) as an indicator of functional outcome. Here, we tested whether including spasticity improved model fit and estimated the effect spasticity had on the outcome. Spasticity was defined by a positive response to the question "Did you have spasticity following your stroke?" on direct interview at 3 months from stroke onset. Patients who had expired by 90 days (n = 30) or did not have spasticity data available (n = 102) were excluded. Spasticity affected the 3-month functional status (β = 0.420, 95 CI = 0.194 to 0.645) after accounting for age, diabetes, leukoaraiosis, and retrospective NIHSS. Using spasticity as a covariable, the model's R (2) changed from 0.599 to 0.622. In our model, the presence of spasticity in the cohort was associated with a worsened 3-month mRS by an average of 0.4 after adjusting for known covariables. This significant adverse effect on functional outcomes adds predictive value beyond previously established factors. PMID:25147752

    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.

    Previous research has shown that 6-month-olds evaluate others on the basis of their social behaviors—they are attracted to prosocial individuals, and avoid antisocial individuals (Hamlin, Wynn, and Bloom, 2007). The current studies investigate these capacities prior to 6 months of age. Results from two experiments indicate that even 3-month-old infants evaluate others based on their social behavior towards third parties, and that negative social information is developmentally privileged.

    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.

    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.

    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

    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

    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.

    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.

    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.

    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.

    Cystic fibrosis (CF) is a hereditary disease of mucous and sweat glands, which affects the respiratory and gastrointestinal systems. Herein, we describe a 3-month-old girl with a history of recurrent episodes of urinary tract infections that required hospitalization. She was referred to our center at the age of three months, with massive gastroesophageal variceal bleeding. In physical examination, she had clubbing, hepatosplenomegaly, and mild ascites. Laboratory studies revealed high serum levels of liver enzymes and low level of Albumin. As of suspicious to CF, sweat tests were performed twice which confirmed the diagnosis of CF. Gastrointestinal bleeding due to gastroesophageal varices is a rare complication of CF, which could result as a consequence of hepatobiliary involvement of disease. Early diagnosis of CF could prevent severe complications and even death in this group of patients. PMID:27107529

    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.

    Full Text Available BACKGROUND: Spontaneous acute exacerbation (AE of chronic hepatitis B (CHB is often detrimental but sometimes leads to sustained immune control and disease remission. The efficacy and safety of nucleos(tide analogues (NAs in patients with spontaneous AE of CHB remains unclear. METHODS: We performed a systematic review and meta-analysis of NAs in patients with spontaneous AE of CHB. We calculated pooled effects of NAs in these patients of each study and conducted quantitative meta-analysis, displaying results using Forest plots. RESULTS: 15 studies were included and substantial heterogeneity was noted in the inclusion/exclusion criteria and controls. Pooled data showed no benefit of lamivudine (LAM vs. untreated controls for transplant-free survival in patients with spontaneous AE of CHB (OR = 0.98 (95% CI, 0.50-1.92; P = 0.956, hepatic decompensation (OR = 0.94 (95% CI, 0.47-1.88; P = 0.862 and liver failure owing to AE (OR = 2.30 (95% CI, 0.35-15.37; P = 0.387 at 3 months. Entecavir achieved even higher short-term mortality than LAM. NAs led to rates of ALT normalization, undetectable HBV DNA, HBeAg loss, HBeAg seroconversion and drug resistance at 1 year in 88%, 61%, 46%, 35% and 5%. Pooled data also showed benefit favoring LAM vs. untreated controls for ALT normalization (OR = 1.98 (95% CI, 1.03-3.80; P = 0.039 and undetectable HBV DNA (OR = 38.50 (95% CI, 7.68-192.99; P<0.001 at 3 months. All NAs were relatively safe and well tolerated. CONCLUSION: NAs had no obvious impact on short-term survival in patients with AE of CHB, despite of possible better antiviral responses. We suggest additional studies to evaluate the efficacy of other NAs and early introduction of immunosuppressant in combination with NAs. We highlight developing prognostic models to identify predictors of mortality and disease progression for AE of CHB.

    IMPORTANCE The very early postnatal period witnesses extraordinary rates of growth, but structural brain development in this period has largely not been explored longitudinally. Such assessment may be key in detecting and treating the earliest signs of neurodevelopmental disorders. OBJECTIVE To assess structural growth trajectories and rates of change in the whole brain and regions of interest in infants during the first 3 months after birth. DESIGN, SETTING, AND PARTICIPANTS Serial structural T1-weighted and/or T2-weighted magnetic resonance images were obtained for 211 time points from 87 healthy term-born or term-equivalent preterm-born infants, aged 2 to 90 days, between October 5, 2007, and June 12, 2013. MAIN OUTCOMES AND MEASURES We segmented whole-brain and multiple subcortical regions of interest using a novel application of Bayesian-based methods. We modeled growth and rate of growth trajectories nonparametrically and assessed left-right asymmetries and sexual dimorphisms. RESULTS Whole-brain volume at birth was approximately one-third of healthy elderly brain volume, and did not differ significantly between male and female infants (347 388 mm3 and 335 509 mm3, respectively, P = .12). The growth rate was approximately 1%/d, slowing to 0.4%/d by the end of the first 3 months, when the brain reached just more than half of elderly adult brain volume. Overall growth in the first 90 days was 64%. There was a significant age-by-sex effect leading to widening separation in brain sizes with age between male and female infants (with male infants growing faster than females by 200.4 mm3/d, SE = 67.2, P = .003). Longer gestation was associated with larger brain size (2215 mm3/d, SE = 284, P = 4×10−13). The expected brain size of an infant born one week earlier than average was 5% smaller than average; at 90 days it will not have caught up, being 2% smaller than average. The cerebellum grew at the highest rate, more than doubling in 90 days, and the hippocampus

    Danshensu (3-(3,4-dihydroxyphenyl) lactic acid), a natural phenolic acid, is isolated from root of Salvia miltiorrhiza, and is widely used as a traditional Chinese medicine for treatment of various cardiovascular diseases. In the present study, toxicity of danshensu was evaluated in male and female dogs after 3-month continuous intravenous infusion. Beagle dogs were treated with danshensu at doses of 17, 50, and 150 mg/kg/day, and observed for 90 days followed by recovery periods. Measurements included clinical observations, body weight, food consumption, temperature, electro-cardiography (EGC), hematology, blood chemistry, urinalysis, gross necropsy, organ weight, and histopathology. No significant adverse effects on these parameters were observed. The only treatment-related finding was a hard knot at injection site observed in the 150 mg/kg group after 2-3 weeks continuous administration, and returned to normal after 3-4 days withdrawal. From these results, it might be concluded that danshensu did not produce any significant cumulative toxicity at the doses administered, as reflected by the various parameters investigated.

    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 had significantly more CD90+/CD44+/CD29+/PDGFRα+primary cells, than the aged rats, suggesting an age dependent shift in the relative cell type distribution within the population. Taken together with recent studies of much more pronounced age differences, our data strongly suggest that donor age is a very critical parameter that should be taken into account in future stem cell studies, especially when using primary cells.

    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.

    The evidence for the efficacy of nonopioid analgesics in the dental pain model was examined by conducting a meta-analysis. Studies were obtained by searching the literature from August 1996 back to 1975 using the terms pain, analgesics, and dentistry. This led to the review of 294 articles, of which 33 studies met the inclusion criteria. Pain scale results were transformed into a common percent scale and converted to N-weighted means with differences in efficacy considered significant using a 95% confidence interval. Collectively, therapeutic doses of the nonsteroidal anti-inflammatory drugs (NSAIDs) commonly used in dentistry were significantly more efficacious than the combination of acetaminophen (600 or 650 mg) with codeine (60 mg). Similarly, specific doses of each of diflunisal, flurbiprofen, ibuprofen, and ketorolac were significantly more efficacious than the commonly used acetaminophen-codeine combination. These quantitative results show that particular NSAIDs may be more efficacious than the acetaminophen-codeine combination for relief of postoperative dental pain. PMID:9481955

    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.

    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

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

    Science.gov (United States)

    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.

    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.

    Scintigraphy has been used as a tool to detect dysfunction of the lung before and after transplantation. The aims of this study were to evaluate the development of the ventilation-perfusion relationships in single lung transplant recipients in the first year, at 3 months after transplantation, and to investigate whether scintigraphic findings at 3 months were predictive for the outcome at 12 months in relation to primary graft dysfunction (PGD) and lung function. A retrospective study was carried out on all patients who prospectively and consecutively were referred for a routine lung scintigraphy procedure 3 months after single lung transplantation (SLTX). A total of 41 patients were included in the study: 20 women and 21 men with the age span of patients at transplantation being 38-66 years (mean ± SD: 54.2 ± 6.0). Patient records also included lung function tests and chest X-ray images. We found no significant correlation between lung function distribution at 3 months and PGD at 72 h. There was also no significant correlation between PGD scores at 72 h and lung function at 6 and 12 months. The same applied to scintigraphic scores for heterogeneity at 3 months compared with lung function at 6 and 12 months. Fifty-five percent of all patients had decreased ventilation function measured in the period from 6 to 12 months. Forty-nine percent of the patients had normal perfusion evaluations, and 51% had abnormal perfusion evaluations at 3 months. For ventilation evaluations, 72% were normal and 28% were abnormal. There was a significant difference in the normal versus abnormal perfusion and ventilation scintigraphic images evaluated from the same patients. Ventilation was distributed more homogenously in the transplanted lung than perfusion in the same lung. The relative distribution of perfusion and ventilation to the transplanted lung of patients with and without a primary diagnosis of fibrosis did not differ significantly from each other. We conclude that PGD

    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.

    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

    This study aims to evaluate the construct validity, internal consistency and cross-cultural invariance of the Generalized Self-Efficacy Scale-Portuguese version (GSE) in a Brazilian and Portuguese sample. The GSE is composed of 10 items, designed to parsimoniously and comprehensively assess self-efficacy beliefs to deal with a wide range of stress-inducing situations. The construct validity (factorial, convergent and discriminant) and internal consistency of the instrument were established within a sample of 304 Portuguese adolescents (study 1) and a sample of 477 Brazilian adolescents (study 2). Then, the invariance of the GSE was tested in a sample of Brazilian adolescents (study 3), using Multigroup Confirmatory Factor Analysis (MGCFA). In the first two studies, the construct validity of the GSE was demonstrated in its three components and the reliability of the scales was confirmed based on satisfactory levels of internal consistency. In the third study, the cross-cultural invariance of the instrument was established. This work adds to previous research on generalized self-efficacy instruments, with good psychometric qualities. Moreover, comparisons can now be made with confidence using this instrument among adolescent samples from Portugal and Brazil. PMID:24230956

    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.

    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.

    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.

    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.)

    Carnosine is a naturally occurring pleotropic dipeptide which influences multiple deleterious mechanisms that are activated during stroke. Numerous published studies have reported that carnosine has robust efficacy in ischemic stroke models. To further evaluate these data, we have conducted a systematic review and meta-analysis of published studies. We included publications describing in vivo models of ischemic stroke where the neuroprotective efficacy of carnosine was being evalu...

    Full Text Available Objective: To study the efficacy of splinting and oral steroids in the management of carpal tunnel syndrome (CTS. Design: Prospective, randomized, open-label, clinical and electrophysiological study with 3-month follow-up. Materials and Methods: Forty patients with CTS were randomly divided into splint group (N-20, wearing splint in neutral position for 4 weeks; and steroid group (N-20, who received oral prednisolone 20 mg/day for 2 weeks followed by 10 mg/day for 2 weeks. Clinical and electrophysiological evaluations were done at baseline and at 1-month and 3-month follow-up. Independent ′t′ test and paired ′t′ test were used for statistical analysis. Outcome Measures: Primary outcome measure was the symptom severity score and functional status score. Secondary outcome measures were median nerve sensory and motor distal latency and conduction velocity. Results: At the end of 3 months, statistically significant improvement was seen in symptom severity score and functional status score in both groups ( P P =0.001 at 3 months in steroid group, while insignificant improvement ( P =0.139 was observed in splint group. On comparing the clinical and electrophysiological improvement between the two groups, except for the functional status score, there was no significant difference at 3-month follow-up. 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.

    Two cholera vaccines, sold as Shanchol and Dukoral, are currently available. This review presents a critical analysis of the protective efficacies of these vaccines. Children under 5 years of age are very vulnerable to cholera and account for the highest incidence of cholera cases and more than half of the resulting deaths. Both Shanchol and Dukoral are two-spaced-dose oral vaccines comprising large numbers of killed cholera bacteria. The former contains Vibrio cholerae O1 and O139 cells, and the latter contains V. cholerae O1 cells with the recombinant B subunit of cholera toxin. In a field trial in Kolkata (India), Shanchol, the preferred vaccine, protected 45% of the test subjects in all of the age groups and only 17% of the children under 5 years of age during the first year of surveillance. In a field trial in Peru, two spaced doses of Dukoral offered negative protection in children under 5 years of age and little protection (15%) in vaccinees over 6 years of age during the first year of surveillance. Little is known about Dukoral's long-term protective efficacy. Both of these vaccines have questionable compositions, using V. cholerae O1 strains isolated in 1947 that have been inactivated by heat and formalin treatments that may denature protein. Immunological studies revealed Dukoral's reduced and short-lived efficacy, as measured by several immunological endpoints. Various factors, such as the necessity for multiple doses, poor protection of children under 5 years of age, the requirement of a cold supply chain, production costs, and complex logistics of vaccine delivery, greatly reduce the suitability of either of these vaccines for endemic or epidemic cholera control in resource-poor settings.

    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

    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.

    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.)

    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.

    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.

    Higher incidence and worse outcomes of laryngospasm during general anesthesia in children than adults have been reported for many years, but few prevention measures are put forward. Efficacy of lidocaine in laryngospasm prevention has been argued for many years and we decided to design this network meta-analysis to assess the efficacy of lidocaine. We conducted an electronic search of six sources and finally included 12 Randomized Controlled Trials including 1416 patients. A direct comparison between lidocaine and placebo revealed lidocaine had the effect on preventing laryngospasm in pediatric surgery (RR = 0.46, 95% CI = [0.30, 0.70], P = 0.0002, I2 = 0%). Both subgroup analysis and network analysis demonstrated that both intravenous lidocaine (subgroup: RR = 0.39, 95% CI = [0.18, 0.86], P = 0.02, I2 = 38%; network: RR = 0.25, 95% CI = [0.04, 0.86]) and topical lidocaine (subgroup: RR = 0.37, 95% CI = [0.19, 0.72], P = 0.003, I2 = 0%; network: RR = 0.14, 95% CI = [0.02, 0.55]) was effective in laryngospasm prevention, while no statistical difference was found in a comparison between intravenous and topical lidocaine. In conclusion, both intravenous and topical lidocaine are effective in laryngospasm prevention in pediatric surgery, while a comparison between them needs more evidences. PMID:27586012

    Williams, David M; Rhodes, Ryan E

    2016-06-01

    Self-efficacy is central to health behaviour theories due to its robust predictive capabilities. In this paper, we present and review evidence for a self-efficacy-as-motivation argument in which standard self-efficacy questionnaires - i.e., ratings of whether participants 'can do' the target behaviour - reflect motivation rather than perceived capability. The potential implication is that associations between self-efficacy ratings (particularly those that employ a 'can do' operationalisation) and health-related behaviours simply indicate that people are likely to do what they are motivated to do. There is some empirical evidence for the self-efficacy-as-motivation argument, with three studies demonstrating causal effects of outcome expectancy on subsequent self-efficacy ratings. Three additional studies show that - consistent with the self-efficacy-as-motivation argument - controlling for motivation by adding the phrase 'if you wanted to' to the end of self-efficacy items decreases associations between self-efficacy ratings and motivation. Likewise, a qualitative study using a thought-listing procedure demonstrates that self-efficacy ratings have motivational antecedents. The available evidence suggests that the self-efficacy-as-motivation argument is viable, although more research is needed. Meanwhile, we recommend that researchers look beyond self-efficacy to identify the many and diverse sources of motivation for health-related behaviours. PMID:25117692

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

    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.

    Background: Dexamethasone is a potent anti-inflammatory, analgesic, and antiemetic drug. Individual randomized controlled trials found a possible benefit of epidural dexamethasone. The purpose of this meta-analysis is to estimate the benefit of epidural dexamethasone on postoperative pain and opioid consumption and to formulate a recommendation for evidence-based practice. Materials and Methods: Prospective, randomized controlled trials comparing the analgesic efficacy of epidural local anesthetic and dexamethasone combination, with local anesthetic alone for postoperative pain management after abdominal surgery, were planned to be included in this meta-analysis. PubMed, PubMed Central, Scopus, and Central Register of Clinical Trials of the Cochrane Collaboration (CENTRAL) databases were searched for eligible controlled trials using the following search words: “Epidural”, “dexamethasone”, and “postoperative pain”, until February 20, 2015. Results: Data from five randomized control trials have been included in this meta-analysis. Epidural dexamethasone significantly decreased postoperative morphine consumption (mean difference −7.89 mg; 95% confidence interval [CI]: −11.66 to −3.71) and number of patients required postoperative rescue analgesic boluses (risk ratio: 0.51; 95% CI: 0.41-0.63). Conclusion: The present data shows that the addition of dexamethasone to local anesthetic in epidural is beneficial for postoperative pain management. PMID:27375389

Increased arterial stiffness is a CVD risk factor. Whole-body vibration (WBV is a simple and convenient exercise for middle-aged and older adults; however, there have been few studies investigating the effect of WBV on arterial stiffness. This study mainly investigated the effect of WBV on arterial stiffness in middle-aged and older adults. Methods: A total of 38 (21 women and 17 men middle-aged and elderly subjects (average age, 61.9 years were randomly divided into the WBV group and the control group for a 3-month trial. The WBV group received an intervention of 30 Hz and 3.2 g WBV in a natural full standing posture at a sports center. The brachial–ankle pulse wave velocity (baPWV, a marker of systemic arterial stiffness, and blood pressure and heart rate were measured before and after the intervention. Results: After 3 months, there were no significant changes in blood pressure or heart rate in both groups. However, the bilateral baPWV was significantly reduced in the WBV group (decreased by 0.65 m/second [P=0.014]; 0.63 m/second [P=0.041] in either side, but not in the control group.

    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.

    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

    Exercise regimens suitable to the elderly remain under investigated; therefore, this study examined the effects of Dance Dance Revolution (DDR) on cognitive control in elderly females. Twenty-six healthy elderly females leading a sedentary lifestyle were assigned to a DDR, brisk walking, or control group. Participants in the DDR and brisk walking groups engaged in moderate physical exercise three times per week for 3 months, whereas the control group maintained a sedentary lifestyle. Each participant performed a flanker task before and after the intervention. The results revealed that both DDR and brisk walking shortened reaction time, N2 latency, and P3 latency relative to those of the control group. These findings suggest that DDR intervention is as effective as that of brisk walking in improving inhibitory control for elderly people. Therefore, DDR can be used as a viable alternative exercise to enhance cognitive function for the elderly and motivate individuals who are less willing to be active. PMID:25595954

    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

    Full Text Available Background. Acupuncture has been shown to reduce preoperative anxiety in several previous randomized controlled trials (RCTs. In order to assess the preoperative anxiolytic efficacy of acupuncture therapy, this study conducted a meta-analysis of an array of appropriate studies. Methods. Four electronic databases (MEDLINE, EMBASE, CENTRAL, and CINAHL were searched up to February 2014. In the meta-analysis data were included from RCT studies in which groups receiving preoperative acupuncture treatment were compared with control groups receiving a placebo for anxiety. Results. Fourteen publications (N = 1,034 were included. Six publications, using the State-Trait Anxiety Inventory-State (STAI-S, reported that acupuncture interventions led to greater reductions in preoperative anxiety relative to sham acupuncture (mean difference = 5.63, P < .00001, 95% CI [4.14, 7.11]. Further eight publications, employing visual analogue scales (VAS, also indicated significant differences in preoperative anxiety amelioration between acupuncture and sham acupuncture (mean difference = 19.23, P < .00001, 95% CI [16.34, 22.12]. Conclusions. Acupuncture therapy aiming at reducing preoperative anxiety has a statistically significant effect relative to placebo or nontreatment conditions. Well-designed and rigorous studies that employ large sample sizes are necessary to corroborate this finding.

    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.

    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.

    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.

    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.

    Constipation is a common childhood complaint. In 90% to 95% of children, constipation is functional, which means that there is no objective evidence of an underlying pathological condition. Polyethylene glycol (PEG or macrogol) solution is an osmotic laxative agent that is absorbed in only trace amounts from the gastrointestinal tract and routinely used to treat chronic constipation in adults. Here, we report the results of a meta-analysis of PEG-based laxatives compared with lactulose, milk of magnesia (magnesium hydroxide), oral liquid paraffin (mineral oil), or acacia fiber, psyllium fiber, and fructose in children. This meta-analysis was conducted in accordance with PRISMA guidelines and involved searches of MEDLINE, Cochrane, EMBASE, and Google Scholar databases up to February 10, 2014, using the keywords (Constipation OR Functional Constipation OR Fecal Impaction) AND (Children) AND (Polyethylene Glycol OR Laxative). Primary efficacy outcomes included a number of stool passages/wk and percentage of patients who reported satisfactory stool consistency. Secondary safety outcomes included diarrhea, abdominal pain, nausea or vomiting, pain or straining at defecation, bloating or flatulence, hard stool consistency, poor palatability, and rectal bleeding. We identified 231 articles, 27 of which were suitable for full-text review and 10 of which were used in the meta-analysis. Patients who were treated with PEG experienced more successful disimpaction compared with those treated with non-PEG laxatives. Treatment-related adverse events were acceptable and generally well tolerated. PEG-based laxatives are effective and safe for chronic constipation and for resolving fecal impaction in children. Children's acceptance of PEG-based laxatives appears to be better than non-PEG laxatives. Optimal dosages, routes of administration, and PEG regimens should be determined in future randomized controlled studies and meta-analyses. PMID:25310742

    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.

    Introduction The goal of endodontic therapy is to completely eliminate the microorganisms and the smear layer from the root canal in order to provide a good seal of the root filling materials. Aim The aim of this study was to find a viable alternative irrigant, which is easily available with less erosion and clinically acceptable smear layer removal by comparing the efficacy of EDTA and commercially available super-oxidized water, named Oxum, as a final rinse on smear layer removal and erosion in relation to coronal, middle and apical thirds of radicular dentin using Scanning Electron Microscope (SEM) analysis. Materials and Methods Freshly extracted 30 human lower second premolar teeth with straight roots and type I canal anatomy were selected. The root canals were cleaned and shaped using Universal Protaper Rotary System. Irrigation was performed with 1 ml of 2.5% of NaOCl solution after each instrument change. The final irrigation (5 ml) sequence was as follows: Group I- 17% EDTA, Group II – OXUM, and Group III - 0.9% saline (control) for one minute. Then, the root canals were finally irrigated with 5ml of distilled water to remove any precipitate. The roots were then gently split into two halves using a chisel and subjected to SEM analysis. Results The SEM photomicrographs were evaluated by two independent examiners and Mann Whitney results showed that there was no statistically significant difference between the two examiners. Non-parametric statistical analysis of all experimental groups showed significant difference between coronal, middle and apical third for smear layer removal with p-value<0.05. For erosion, in group II (oxum) showed statistically significant difference between coronal, middle and apical third and it showed significantly less dentine erosion when compared to EDTA. Conclusion Within the limitations of the present study, Oxum the commercially available super-oxidized water proved to be equally effective in smear layer removal with less

    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.

    An increasing number of studies have been examining non-pharmacological methods to improve the quality of sleep, including the use of music and other types of auditory stimulation. While many of these studies have found significant results, they suffer from a combination of subjective self-report measures as the primary outcome, a lack of proper controls, often combine music with some type of relaxation therapy, or do not randomise subjects to control and treatment conditions. It is therefore difficult to assess the efficacy of music to induce or improve sleep. The present study therefore examined the effects of music using standard polysomnographic measures and quantitative analysis of the electroencephalogram, along with subjective ratings of sleep quality. In addition, a tones condition was used to compare any effects of music with the effects of general auditory stimulation. Using a counter-balanced within-subjects design, the music was not significantly better than the tones or control conditions in improving sleep onset latency, sleep efficiency, wake time after sleep onset, or percent slow wave sleep, as determined by objective physiological criteria.

    Soldiers and veterans diagnosed with PTSD benefit less from psychotherapy than non-military populations. The current meta-analysis identified treatment predictors for traumatised soldiers and veterans, using data from studies examining guideline recommended interventions, namely: EMDR, exposure, cognitive, cognitive restructuring, cognitive processing, trauma-focused cognitive behavioural, and stress management therapies. A systematic search identified 57 eligible studies reporting on 69 treated samples. Exposure therapy and cognitive processing therapy were more effective than EMDR and stress management therapy. Group-only therapy formats performed worse compared with individual-only formats, or a combination of both formats. After controlling for study design variables, EMDR no longer negatively predicted treatment outcome. The number of trauma-focused sessions, unlike the total number of psychotherapy sessions, positively predicted treatment outcome. We found a relationship between PTSD pretreatment severity levels and treatment outcome, indicating lower treatment gains at low and high PTSD severity levels compared with moderate severity levels. Demographic variables did not influence treatment outcome. Consequently, soldiers and veterans are best served using exposure interventions to target PTSD. Our results did not support a group-only therapy format. Recommended interventions appear less effective at relatively low and high patient PTSD severity levels. Future high-quality studies are needed to determine the efficacy of EMDR. PMID:26164548

    Full Text Available BACKGROUND AND OBJECTIVES: The goal of this meta-analysis study was to perform a systematic review of the literature on the effects of ketamine on postoperative pain following tonsillectomy and adverse effects in children. SUBJECTS AND METHODS: Two authors independently searched three databases (MEDLINE, SCOPUS, Cochrane from their inception of article collection to February 2014. Studies that compared preoperative ketamine administration (ketamine groups with no treatment (control group or opioid administration (opioid group where the outcomes of interest were postoperative pain intensity, rescue analgesic consumption, or adverse effects (sedation, nausea and vomiting, bad dream, worsening sleep pattern, and hallucination 0-24 hours after leaving the operation room were included in the analysis. RESULTS: The pain score reported by the physician during first 4 hours and need for analgesics during 24 hours postoperatively was significantly decreased in the ketamine group versus control group and was similar with the opioid group. In addition, there was no significant difference between ketamine and control groups for adverse effects during 24 hours postoperatively. In the subgroup analyses (systemic and local administration regarding pain related measurements, peritonsillar infiltration of ketamine was more effective in reducing the postoperative pain severity and need for analgesics. CONCLUSION: Preoperative administration of ketamine systemically or locally could provide pain relief without side-effects in children undergoing tonsillectomy. However, considering the insufficient evaluation of efficacy of ketamine according to the administration methods and high heterogeneity in some parameters, further clinical trials with robust research methodology should be conducted to confirm the results of this study.

    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. PMID:26771568

    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.

    A randomized controlled trial examined the effect of two physical activity modes on changes in self-efficacy over the course of a 12-month period in older, formerly sedentary adults (N = 174, M age = 65.5 years). Participants were randomized into either an aerobic activity group or a stretching and toning group. Structural equation modeling was employed to conduct multiple sample latent growth curve analyses of individual growth in exercise and physical self-efficacy over time. Results revealed a curvilinear growth pattern for both types of efficacy with increases occurring over the first 6 months followed by declines at the 6-month follow-up. There was a significant treatment by mean level growth interaction for exercise efficacy with both groups increasing over time, but the aerobic group evidenced a twofold increase in growth over the stretching group. Structural analyses indicated that frequency of exercise participation was a significant predictor of overall growth in efficacy, and improvements in fitness were only related to exercise efficacy growth in the stretching group. Findings are discussed in terms of social cognitive theory and further application of latent growth curve modeling to studies of physical activity effects in older adults. PMID:10542821

    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. PMID:24511358

    Phytoremediation efficacy of Lemna minor and Azolla pinnata in decontaminating metals from coal mine effluent (CME) was analyzed using bioassays. Catfish Heteropneustes fossilis were exposed to both the phytoremediated CMEs for the metal bioaccumulation analysis and biochemical alteration in seven vital tissues. Gross concentration of metals accumulated in liver, kidneys, air breathing organs (ABO), skin and muscle were greater in fish exposed to A. pinnata remediated CME (AP-CME) than those exposed to L. minor remediated CME (LP-CME). Total protein concentrations of all the tissues were greater in fish exposed to LP-CME than to AP-CME. Glycogen concentrations were greater in muscle, brain, ABO and skin of LP-CME exposed fish. In remaining tissues (liver, kidneys and gills) concentrations of glycogen were more in AP-CME exposed ones. Total lipid and total DNA concentrations were greater in most of the tissues of fish exposed to LP-CME than to AP-CME. The total RNA concentrations were elevated only in muscle, liver, kidneys and brain of LP-CME exposed fish; in rest of the tissues (gills, ABO and skin) it was greater in AP-CME exposed fish. The values of condition factor (K) and organosomatic index (OSI) of fish exposed to LP-CME and AP-CME were insignificant to those of wild fish. However, the improvements in the biomolecules concentration of tissues of fish exposed to either of the phytoremediated effluent were not equivalent to their concentration in the wild fish. Thus, decontamination of CME by either of these macrophytes was not complete and prolonged exposure of even phytoremediated CMEs exerts deleterious effects on the fish. PMID:23566881

    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.

    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.

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

    Directory of Open Access Journals (Sweden)

    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.

    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 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

    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.

    [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.

    1998-12-01

    The goal of Project Inquiry, a two-year long multiphase study, was to transform the delivery of science instruction from a traditional, textbook driven delivery approach to a hands-on, minds-on, constructivist approach. Teachers from a midwestern urban school district were trained in constructivism while learning physics concepts and content through guided inquiry instruction in collaborative groups. The objectives aimed to increase teachers' content expertise and science teaching efficacy, as well as to have teachers become better facilitators of learning. Phase two of the three phases of Project Inquiry was the focus of this study. Fifty-seven teachers participated in Phase two, which began with an intense two week summer institute in 1995. A longitudinal time-series (OxOO), quasi-experimental research design was used to investigate the relationship between science teaching efficacy scores and gains in physics content knowledge. The data consisted of: (a) six sets of pre and post physics content knowledge test scores (electricity, magnetism, matter and balance); (b) three sets of STEBI-A (inservice), Science Teaching Efficacy Belief Instrument scores, a pre to post, pre to follow-up, and post to follow-up; and (c) demographic variables that were used as covariates, grade taught, years of experience, and postbaccalaureate training. Using the general linear model with an Alpha level of.05, and testing the hypothesized relationships, results indicated that although there were significant positive gains in content knowledge (p =.000) and science teaching efficacy (p =.000), the overall average gains in physics content knowledge were not predictive of gains in either Personal Science Teaching Efficacy or Science Outcome Expectancy. Post hoc analysis used individual content gain scores, in regression models that included the three covariates: grade taught, years of experience, and post baccalaureate training, to test the relationship between knowledge gains and

    Full Text Available In this study, the efficacy of proanthocyanidins (PCs against oxidative damage was systematically reviewed to facilitate their use in various applications.A meta-analysis was performed by two researchers. Each investigator independently searched electronic databases, including Cochrane, PubMed, Springer, Web of Science, China National Knowledge Infrastructure (CKNI, China Science and Technology Journal Database (CSTJ, and WanFang Data, and analyzed published data from 29 studies on the effects of PCs against oxidative damage. Oxidative stress indexes included superoxide dismutase (SOD, malondialdehyde (MDA, catalase (CAT, glutathione (GSH, glutathione peroxidase (GPx, and total antioxidative capacity (T-AOC.Compared with the oxidative damage model group, PCs effectively improved the T-AOC, SOD, GSH, GPx, and CAT levels, and reduced the MDA levels; these differences were statistically significant (P < 0.05. In studies that used the gavage method, SOD (95% CI, 2.33-4.00 and GPx (95% CI, 2.10-4.05 were 3.16-fold and 3.08-fold higher in the PC group than in the control group, respectively. In studies that used the feeding method, SOD (95% CI, 0.32-1.74 and GPx (95% CI, -0.31 to 1.65 were 1.03-fold and 0.67-fold higher in the PC group than in the control group, respectively. Statistically significant differences in the effects of PCs (P < 0.00001 were observed between these two methods. MDA estimated from tissue samples (95% CI, -5.82 to -2.60 was 4.32-fold lower in the PC group than in the control group. In contrast, MDA estimated using serum samples (95% CI, -4.07 to -2.06 was 3.06-fold lower in the PC group than in the control group. The effect of PCs on MDA was significantly greater in tissue samples than in serum samples (P = 0.02.PCs effectively antagonize oxidative damage and enhance antioxidant capacity. The antagonistic effect may be related to intervention time, intervention method, and the source from which the indexes are estimated.

    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

    Escitalopram is the most selective of the serotonin reuptake inhibitor (SSRI) antidepressants. We conducted a meta-analysis of placebo-controlled studies where escitalopram was used to treat patients with social anxiety disorder (SAD). Data from all randomised, double-blind placebo-controlled studies in SAD with escitalopram from both specialist settings and general practice were used. Patients met the DSM-IV criteria for SAD, were ≥18 years old, and had a Liebowitz Social Anxiety Scale (LSAS) ≥60. The primary outcome measure was the estimated treatment difference in LSAS total score at Week 12. Secondary outcome measures included the estimated treatment difference in the Clinical Global Impression-Severity (CGI-S) score at Week 12. A total of 1598 patients from 3 randomised controlled trials were included in the analyses. Escitalopram (n=1061) was superior to placebo (n=537), with an estimated treatment difference on the LSAS of -9.2 points (95%CI: [-14.4; -4.0], pescitalopram 5mg/day), -4.6 points (95%CI: [-8.1; -1.0], pescitalopram 10mg/day), -10.1 points (95%CI: [-13.7; -6.5], pescitalopram 20mg/day) and -7.3 points (95%CI: [-12.3; -2.2], pescitalopram 10-20mg/day). For the CGI-S, the corresponding values were -0.55 points (95%CI: [-0.79; -0.31], pescitalopram 5mg/day), -0.26 points (95%CI: [-0.42; -0.10], pescitalopram 10mg/day), -0.48 points (95%CI: [-0.64; -0.31], pescitalopram 20mg/day) and -0.29 points (95%CI: [-0.51; -0.07], pescitalopram 10-20mg/day). The withdrawal rate due to adverse events was 7.2% for escitalopram, compared with 4.3% for placebo (pescitalopram showed significant superiority in efficacy versus placebo in the treatment of patients with SAD.

    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 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.

  2. Efficacy analysis of first radioiodine ablation of residual thyroid tissue in postoperative patients with thyroid cancer

    International Nuclear Information System (INIS)

    Objective: To study the influence of age, sex, type of surgery, pathologic type of the tumor, postoperative time to the administration and the dose of radioiodine, TSH level and the existence of radioiodine uptake beyond thyroid to first radioiodine ablation of residual thyroid tissue (RTT) in well-differentiated thyroid cancer after surgery. Methods: Eighty-five well-differentiated thyroid cancer patients after surgery were ablated of RTT with radioiodine from 1975 to 1998 and were followed up for 3 - 6 months after ablation. Using the absence of visible uptake compared with background as the criterion for successful ablation. Results: Fifty-eight of 85 patients (68.2%) had successful ablation of RTT after the first administration of radioiodine. The results were statistically related to the type of surgery, the time after surgery to the ablation and the dosage of radioiodine, TSH level and the simultaneous existence of radioiodine uptake in metastatic site in the patients gained successfully ablation (P < 0.05), there were no statistically significant relation with age, sex and pathologic type of tumor. Conclusions: In well-differentiated thyroid cancer, there would be better effect of first ablation of RTT with suitable dosage of radioiodine, total thyroidectomy, above 50 mU/L TSH level,ablation conducted within 3 months after surgery and radioiodine uptake found only in RTT. The effectiveness of first ablation of RTT possesses no relationship with the age, sex and the pathologic type of the tumor

    The climate sensitivity parameter has long been assumed to be constant. However, recent studies found that the climate sensitivity parameter varies, not only amongst models for the same forcing, but also within the same model where it may strongly depend on the strength and the type of the applied forcing. The so-called efficacy differences are essential to assess the relative importance of several contributing agents to a total climate impact. Running equilibrium climate change s...

    Topical minoxidil has become a mainstay in the treatment of androgenetic alopecia (AGA). Despite being a longstanding treatment for AGA, relatively few reviews of its efficacy have been published. The current study sought to synthesize the available efficacy data by performing a systematic review of the literature and conducting random-effects pairwise meta-analyses for the outcomes percent increase in hair count from baseline, investigator assessment, and patient self-assessment. Results showed that minoxidil is more effective than placebo in promoting total and nonvellus hair growth (mean difference [MD], 16.68; 95% confidence interval [CI], 9.34-24.03 and MD, 20.90; 95% CI, 9.07-32.74). A significantly higher proportion of participants in the minoxidil group had greater hair growth than participants in the placebo group as judged by both investigators and self-reports (relative risk [RR], 2.28; 95% CI, 1.58-3.31 and RR, 1.56; 95% CI, 1.34-1.80). Despite significant clinical efficacy, cosmetically acceptable results are present in only a subset of patients. Compliance is thought to be a major limiting factor and is being addressed by novel formulations and combinations. PMID:26380504

    Vascular cognitive impairment with no dementia (VCIND) refers to a transitional state and will progress to dementia. Currently, effective medicines to control VCIND are surprisingly scarce. Acupuncture intervention is frequently advocated as an adjunct treatment for VCIND in recent studies. So the aim of this meta-analysis was to assess the clinical efficacy and safety of acupuncture for VCIND. The literature search was conducted in English and Chinese databases from inception until July 2015, and 15 study populations were included in the meta-analysis. Mean differences with their 95% confidence interval for continuous data were calculated with fixed effect model or random effect model using Rev Man 5.3 software. This review included 1148 subjects. The methodological qualities of the included studies were judged to be generally poor because plenty of trials had high or unclear risk of bias. The results of meta-analysis showed that acupuncture therapy was more effective in treating VCIND when compared with conventional therapy or pharmacological treatment. Two trials showed minor adverse events and two other trails mentioned no adverse events had existed. Current evidences cautiously suggest that acupuncture therapy can improve the clinical efficacy for VCIND. More rigorously designed studies are needed to further confirm effectiveness and safety of acupuncture therapy in patients with VCIND. PMID:27237931

    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.

    Full Text Available 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 nonsignificant 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.

    Purpose Retinoblastoma is the most common primary malignant intra-ocular tumor in children. Although intra-arterial chemotherapy (IAC) by selectively infusing chemotherapy through the ophthalmic artery has become an essential technique in the treatment of advanced intra-ocular retinoblastoma in children, the outcome of IAC as primary therapy for infants less than 3 months of age remains unknown. In this retrospective study, we reviewed the outcome of IAC as primary therapy for retinoblastoma in infants less than 3 months of age. Methods We retrospectively reviewed ten retinoblastoma patients attending our center from January 2009 to September 2015 and beginning primary IAC before the age of 3 months. The patient characteristics, overall outcomes and therapy-related complications were assessed. Results The mean patient age at the first IAC treatment was 10.4 weeks (range 4.9–12.9 weeks). These eyes were classified according to the International Classification of Retinoblastoma (ICRB) as group A (n = 0), B (n = 2), C (n = 0), D (n = 9), or E (n = 2). A total of 28 catheterizations were performed, and the procedure was stopped in one patient because of internal carotid artery spasm. Each eye received a mean of 2.6 cycles of IAC (range 2–4 cycles). After IAC with a mean follow-up of 28.3 months (range 9–65 months), tumor regression was observed in 12 of 13 eyes. One eye was enucleated due to tumor progression. All patients are alive and no patient has developed metastatic disease or other malignancies. Conclusions Our experience suggests IAC as primary therapy is a feasible and promising treatment for retinoblastoma in infants less than 3 months of age. PMID:27504917

    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.

    Full Text Available Acupuncture has emerged as an alternative therapy for Bell's palsy in both adults and children. However, the use of acupuncture is controversial. We conducted a systematic review and meta-analysis to assess the efficacy of acupuncture for Bell's palsy. We searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials, irrespective of any language restrictions. Randomized controlled trials comparing acupuncture with other therapies for Bell's palsy in adults or children were included. Fourteen randomized controlled trials involving 1541 individuals were included in this meta-analysis. Significant association was observed in acupuncture with a higher effective response rate for Bell's palsy (relative risk, 1.14; 95% confidence interval, 1.04-1.25; P = 0.005 but there was a heterogeneity among the studies (I2 = 87%. An assessment of the included studies revealed a high risk of bias in methodological quality. An evaluation of the incidence of complications was not available, owing to incomplete data. Acupuncture seems to be an effective therapy for Bell's palsy, but there was insufficient evidence to support the efficacy and safety of acupuncture. However, the results should be interpreted cautiously, because of the poor quality and heterogeneity of the included studies.

    Objective: To evaluate the safety and efficacy of the preoperative neoadjuvant chemotherapy for patients with cervical cancer. Methods: A systematic literature search was conducted using the PubMed, EMBASE and Cochrane databases. Studies comparing combined neoadjuvant chemotherapy treatment (NACT)/radical surgery treatment (RST) with RST alone in patients with cervical cancer were eligible for inclusion. Results: Eight studies were finally included in this meta analysis, involving a total of 1302 patients. Meta analysis shows that NACT might have lower lymph node metastasis than RST [OR=0.57, 95% CI (0.41, 0.79), P=0.0008]. However, there are no differentiation between two groups in operation time [SMD=0.16, 95% CI (-0.08, 0.48), P=0.19], intraoperative estimated blood loss [SMD=0.20, 95% CI (-0.19, 0.58), P=0.48], intraoperative and postoperative complication rates [OR=1.33, 95% CI (0.45, 3.92), P=0.60], overall survival rate [OR=1.07, 95% CI (0.48, 2.41), P=0.86] and recurrence rate [OR=1.06, 95% CI (0.56, 2.03), P=0.85]. Conclusions: The safety and efficacy of two treatments are similarly. However, NACT can reduce the rate of lymph node metastasis, which is an independent risk factor for cervical cancer prognosis and may improve the prognosis of cervical cancer. PMID:26628951

    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. 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 supportive

    Background Simvastatin is a statin used to lower low-density lipoprotein cholesterol, but has limitations in patients on complicated regimens due to concerns about drug-drug interactions. Pitavastatin is a newly developed statin with limited drug-drug interactions. We conducted a meta-analysis to compare the clinical efficacy of simvastatin and pitavastatin in the control of hypercholesterolemia. Methods Randomized clinical trials comparing the efficacy of pitavastatin and simvastatin were identified by searching PubMed (2000–2014) and EMBASE (2000–2014). The primary outcome subjected to meta-analysis was percent change in low-density lipoprotein cholesterol compared with baseline. Results Four clinical trials were selected for meta-analysis. A total of 908 patients treated with pitavastatin (2 or 4 mg/day) and 381 patients treated with simvastatin (20 or 40 mg/day) were included in the final statistical analysis. No statistically significant difference was identified between treatment with pitavastatin 4 mg/day and treatment with simvastatin 40 mg/day for 12 weeks (mean difference −0.66; 95% confidence interval −2.92, 1.61; P=0.57). Similarly, no statistically significant difference was observed between pitavastatin 2 mg/day and simvastatin 20 mg/day for 4 weeks (mean difference −2.19; 95% confidence interval −0.11, 4.49; P=0.06). Treatment with pitavastatin was noninferior to simvastatin in all of the secondary outcomes and the safety profile was similar between the two statins. Conclusion Pitavastatin is noninferior to simvastatin in lowering low-density lipoprotein cholesterol. PMID:25848221

    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.

    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. PMID:25926790

    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.

    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

  20. Sixteen multidetector row computed tomography of pulmonary veins: 3-months' follow-up after treatment of paroxysmal atrial fibrillation with cryothermal ablation

    International Nuclear Information System (INIS)

    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/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.

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.

    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.

    2016-01-01

    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. PMID:27274753

    To assess the efficacy and safety of local anaesthetics for premature ejaculation (PE),a systematic review of the literature was performed using the Cochrane Library,PUBMED and EMBASE.We screened and retrieved the randomized controlled trials on the treatment of PE with local anaesthetics.End points included intravaginal ejaculation latency time (IELT),patient-reported outcome assessments and adverse events.Meta-analyses were conducted with Stata 11.0.In total,seven publications involving 566 patients with local anaesthetics and 388 with placebos strictly met our eligibility criteria.Meta-analyses showed that after the patients were treated with the local anaesthetics,the value of the standardized mean difference of the changes in IELT was 5.02 (95% CI:3.03-7.00).A higher rate of adverse events occurred compared with placebos (odds ratio:3.30,95% CI:1.71-6.36),but these events were restricted to local side effects.In addition,significantly greater improvement was observed in patient-reported outcomes.In summary,local anaesthetics can prolong IELT and improve ejaculatory control and sexual satisfaction.

    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.

    Diphenylcyclopropenone (DPCP) is widely considered the most effective topical immunotherapy for refractory or extensive alopecia areata (AA), but questions regarding how long to try DPCP therapy before terminating and what factors are prognostic of therapeutic success still remain unanswered. In this retrospective study of 50 AA patients, we evaluated DPCP efficacy and identified patient factors predictive of therapeutic success/failure. The median duration of DPCP treatment was 3 years, with 47% patients experiencing their first regrowth in the first 6 months of DPCP therapy, 20% between 6 months-1 year, and 8% between 1-2 years. In our study, treatment success, defined as ⩾50% terminal hair regrowth, was reached in 71% of alopecia totalis patients and in 56% of alopecia universalis patients. Three factors were statistically significant predictors of poor treatment outcome-extent of hair loss before DPCP treatment, history of thyroid disease, and extent of body hair involvement. Relapse was observed in 44% of patients and significantly associated with history of thyroid disease. Common side effects were itching, rash, and local lymphadenopathy. The results of this study support our belief that DPCP therapy is a viable treatment option, can be successfully accomplished at home, and should not be terminated before 2 years. PMID:26551948

    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. PMID:26204904

    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.

  15. Determinants of the Efficacy of Cardiac Ischemic Preconditioning: A Systematic Review and Meta-Analysis of Animal Studies.

    Kimberley E Wever

    Full Text Available Ischemic preconditioning (IPC of the heart is a protective strategy in which a brief ischemic stimulus immediately before a lethal ischemic episode potently limits infarct size. Although very promising in animal models of myocardial infarction, IPC has not yet been successfully translated to benefit for patients.To appraise all preclinical evidence on IPC for myocardial infarction and identify factors hampering translation.Using systematic review and meta-analysis, we identified 503 animal studies reporting infarct size data from 785 comparisons between IPC-treated and control animals. Overall, IPC reduced myocardial infarction by 24.6% [95%CI 23.5, 25.6]. Subgroup analysis showed that IPC efficacy was reduced in comorbid animals and non-rodents. Efficacy was highest in studies using 2-3 IPC cycles applied <45 minutes before myocardial infarction. Local and remote IPC were equally effective. Reporting of study quality indicators was low: randomization, blinding and a sample size calculation were reported in 49%, 11% and 2% of publications, respectively.Translation of IPC to the clinical setting may be hampered by the observed differences between the animals used in preclinical IPC studies and the patient population, regarding comorbidity, sex and age. Furthermore, the IPC protocols currently used in clinical trials could be optimized in terms of timing and the number of ischemic cycles applied. In order to inform future clinical trials successfully, future preclinical studies on IPC should aim to maximize both internal and external validity, since poor methodological quality may limit the value of the preclinical evidence.

    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 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

    @@ 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.

    The aim of this study was to evaluate the efficacy and safety of odanacatib (ODN) for the treatment of osteoporosis, using data in studies reported in the literature. We performed a literature search to compare the outcomes of applications of once-weekly ODN 50 mg and control. The outcomes of osteoporosis evaluated include primary outcome as bone mineral density (BMD) at different skeletal sites, and secondary outcomes, including adverse events (AEs), such as incidence of skin AEs, fracture, and serious adverse events (SAEs). Four trials were included. Mean difference (95% CI) of lumbar spine BMD was 3.41 (1.57-5.24) at 12 months and 4.89 (2.72-7.05) at 24 months; mean difference (95% CI) of femoral neck BMD was 1.90 (0.73-3.08) at 12 months and 3.85 (2.55-5.15) at 24 months; mean difference (95% CI) of total hip BMD was 2.65 (1.20-4.09) at 12 months and 3.70 (1.76-5.64) at 24 months; risk ratio (95% CI) of AEs was 0.98 (0.91-1.07); risk ratio (95% CI) of SAEs was 1.11 (0.72-1.72); risk ratio (95% CI) of skin AEs was 0.92 (0.63-1.35); and risk ratio (95% CI) of fracture was 0.34 (0.16-0.70). In this study, application of 50 mg ODN produced significantly greater BMD increases and lower fracture incidence than that of the control. In addition, ODN was generally well tolerated.

    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.

    Full Text Available Renal sodium-dependent glucose co-transporter 2 (SGLT2 is one of the most promising targets for the treatment of type 2 diabetes. Two SGLT2 inhibitors, dapagliflozin and canagliflozin, have already been approved for use in USA and Europe; several additional compounds are also being developed for this purpose. Based on the in vitro IC50 values and plasma concentration of dapagliflozin measured in clinical trials, the marketed dosage of the drug was expected to almost completely inhibit SGLT2 function and reduce glucose reabsorption by 90%. However, the administration of dapagliflozin resulted in only 30–50% inhibition of reabsorption. This study was aimed at investigating the mechanism underlying the discrepancy between the expected and observed levels of glucose reabsorption. To this end, systems pharmacology models were developed to analyze the time profile of dapagliflozin, canagliflozin, ipragliflozin, empagliflozin, and tofogliflozin in the plasma and urine; their filtration and active secretion from the blood to the renal proximal tubules; reverse reabsorption; urinary excretion; and their inhibitory effect on SGLT2. The model shows that concentration levels of tofogliflozin, ipragliflozin, and empagliflozin are higher than levels of other inhibitors following administration of marketed SGLT2 inhibitors at labeled doses and non-marketed SGLT2 inhibitors at maximal doses (approved for phase 2/3 studies. All the compounds exhibited almost 100% inhibition of SGLT2. Based on the results of our model, two explanations for the observed low efficacy of SGLT2 inhibitors were supported: 1 the site of action of SGLT2 inhibitors is not in the lumen of the kidney’s proximal tubules, but elsewhere (e.g., the kidneys proximal tubule cells; and 2 there are other transporters that could facilitate glucose reabsorption under the conditions of SGLT2 inhibition (e.g., other transporters of SGLT family.

    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.

    Model for end-stage liver disease (MELD) scoring was initiated using traditional statistical technique by assuming a linear relationship between clinical features, but most phenomena in a clinical situation are not linearly related. The aim of this study was to predict 3-month mortality risk of acute-on-chronic hepatitis B liver failure (ACHBLF) on an individual patient level using an artificial neural network (ANN) system. The ANN model was built using data from 402 consecutive patients with ACHBLF. It was trained to predict 3-month mortality by the data of 280 patients and validated by the remaining 122 patients. The area under the curve of receiver operating characteristic (AUROC) was calculated for ANN and MELD-based scoring systems. The following variables age (P < 0.001), prothrombin activity (P < 0.001), serum sodium (P < 0.001), total bilirubin (P = 0.015), hepatitis B e antigen positivity rate (P < 0.001) and haemoglobin (P < 0.001) were significantly related to the prognosis of ACHBLF and were selected to build the ANN. The ANN performed significantly better than MELD-based scoring systems both in the training cohort (AUROC = 0.869 vs 0.667, 0.591, 0.643, 0.571 and 0.577; P < 0.001, respectively) and in the validation cohort (AUROC = 0.765 vs 0.599, 0.563, 0.601, 0.521 and 0.540; P ≤ 0.006, respectively). Thus, the ANN model was shown to be more accurate in predicting 3-month mortality of ACHBLF than MELD-based scoring systems. PMID:23490369

    Bladder pain syndrome/interstitial cystitis (BPS/IC) is a chronic disease characterised by persistent irritating micturition symptoms and pain. The objective was to compare the clinical efficacy of currently available products for intravesical therapy of BPS/IC and to assess their pharmacoeconomic impact. A Pubmed/Medline database search was performed for articles on intravesical therapy for BPS/IC. A total of 345 publications were identified, from which 326 were excluded. Statistical evaluation was performed with effect size (ES) assessment of symptom reduction and response rates. The final set of 19 articles on intravesical BPS/IC therapy included 5 prospective controlled trials (CTs), the remaining were classified as uncontrolled clinical studies. The total number of patients included was 801, 228 of whom had been evaluated in a CT. For CTs, the largest ES for symptom reduction as well as response rate was observed for high molecular weight hyaluronic acid (HMW-HA), with similar findings in two uncontrolled studies with HMW-HA. The number needed to treat to achieve a response to intravesical therapy was 2.67 for intravesical pentosan polysulphate and 1.31 for HMW-HA which were superior to all other instillates. HMW-HA was significantly superior in cost effectiveness and cost efficacy to all other instillation regimes. The present meta-analysis combined medical and pharmacoeconomic aspects and demonstrated an advantage of HMW-HA over other instillation agents; however, direct comparisons between the different products have not been performed to date in properly designed controlled studies.

    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. PMID:26693420

    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.

    Background/Aims: Non-pancreatic elevations of serum lipase have been reported, and differential diagnosis is necessary for clinical practice. This study aimed to evaluate the clinical efficacy of serum lipase subtype analysis for the differential diagnosis of pancreatic and non-pancreatic lipase elevation. Methods: Patients who were referred for the serum lipase elevation were prospectively enrolled. Clinical findings and serum lipase subtypes were analyzed and compared by dividing the patients into pancreatitis and non-pancreatitis groups. Results: A total of 34 patients (12 pancreatitis vs. 22 non-pancreatitis cases) were enrolled. In univariate analysis, the fraction of pancreatic lipase (FPL) in the total amount of serum lipase subtypes was statistically higher in patients with pancreatitis ([median, 0.004; interquartile range [IQR], 0.003 to 0.011] vs. [median, 0.002; IQR, 0.001 to 0.004], p = 0.04). Based on receiver operating characteristic curve analysis for the prediction of acute pancreatitis, FPL was the most valuable predictor (area under the receiver-operating characteristic curve [AUROC], 0.72; 95% confidence interval [CI], 0.54 to 0.86; sensitivity, 83.3%; specificity, 63.6%; positive predictive value, 55.6%; negative predictive value, 97.5%). In multivariate analysis, a cut-off value higher than 0.0027 for the FPL was associated with acute pancreatitis (odds ratio, 8.3; 95% CI, 1.3 to 51.7; p = 0.02). Conclusions: The results did not support that serum lipase subtype analysis could replace standard lipase measurement for the diagnosis of acute pancreatitis. However, the test demonstrated adequate sensitivity for use in triage or as an add-on test for serum lipase elevation. PMID:27243230

    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.

    2014-01-01

    Background Shivering is a very common complication in the postanesthesia period. Increasing studies have reported ondansetron may be effective in prevention of postanesthesia shivering (PAS). However, the results remained controversial; hence we conducted a meta-analysis of randomized controlled trials to evaluate the efficacy and safety of ondansetron on the prevention of postanesthesia shivering. Methods PubMed and Embase databases were searched to identify the eligible randomized controlled trials assessing the effect of ondansetron on the prevention of PAS. Results were expressed as risk ratios (RRs) with accompanying 95% confidence intervals (CIs). The meta-analysis was performed with fixed-effect model or random-effect model according to the heterogeneity. Results Six trials including 533 subjects were included. Compared with placebo, ondansetron was associated with a significant reduction of PAS (RR 0.43, 95% CI, 0.27-0.70), without an increased risk of bradycardia (RR 0.37, 95% CI, 0.12-1.15). Compared with meperidine, no difference was observed in the incidence of PAS (RR 0.68, 95% CI, 0.39-1.19) and bradycardia (RR 2.0, 95% CI, 0.38-10.64). Conclusions Ondansetron has a preventive effect on PAS without a paralleled side effect of bradycardia. PMID:24588846

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

    Since the evidence regarding statin therapy in PAH has not been conclusive, we assessed the impact of statin therapy in PAH through a systematic review and meta-analysis of available studies. We searched selected databases up to August 1, 2015 to identify the studies investigating the effect of statin administration on PAH. Meta-analysis was performed using either a fixed-effects or random-effect model according to I2 statistic. Meta-analysis of 8 studies with 665 patients did not suggest any significant improvement in 6-min walking distance (6MWD) by statin therapy (weighed mean difference [WMD]: −6.08 m, 95% confidence interval [CI]: −25.66, 13.50, p = 0.543; Q = 8.41, I2 = 28.64%). Likewise, none of the other indices including pulmonary arterial pressure (WMD: −0.97 mmHg, 95%CI: −4.39, 2.44, p = 0.577; Q = 14.64, I2 = 79.51%), right atrial pressure (WMD: 1.01 mmHg, 95%CI: −0.93, 2.96, p = 0.307; Q = 44.88, I2 = 95.54%), cardiac index (WMD: 0.05 L/min/m2, 95%CI: −0.05, 0.15, p = 0.323; Q = 3.82, I2 = 21.42%), and pulmonary vascular resistance (WMD: −1.42 dyn*s/cm5, 95%CI: −72.11, 69.27, p = 0.969; Q = 0.69, I2 = 0%) was significantly altered by statin therapy. In conclusion, the results of the meta-analysis did not show a statistically significant effect of statin therapy in the improvement of 6MWD, pulmonary arterial pressure, right atrial pressure, cardiac index and pulmonary vascular resistance.

    A growing line of research has highlighted that e-technologies may play a promising role in improving breastfeeding outcomes. The objective of this review was to synthesise the best of available evidence by conducting a meta-analysis to evaluate whether e-technologies have had any effect in improving breastfeeding outcomes among perinatal women. The review was conducted using nine electronic databases to search for English-language research studies from 2007 to 2014. A 'risk of bias' table was used to assess methodological quality. Meta-analysis was performed with the RevMan software. The Q test and I(2) test was used to assess the heterogeneity. The test of overall effect was assessed using z-statistics at P attitude (z = 3.01, P = 0.003) and breastfeeding knowledge (z = 4.54, P = < 0.00001) in subgroup analyses. This review provides support for the development of web-based, texting messaging, compact disc read-only memory, electronic prompts and interactive computer agent interventions for promoting and supporting breastfeeding.

    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

    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 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.

    Full Text Available Objective. To systematically review the efficacy and potential immunomodulatory effect of ulinastatin combined with thymosin α1 (UTI for sepsis. Design. A systematic review and meta-analysis of randomized controlled trials (RCTs. Data Sources. The following databases: PubMed, Embase, and Cochrane Central were searched to identify related clinical trials. The search terms were “ulinastatin”, “thymosin”, and “sepsis”. Results. Six RCTs, 944 septic patients in total, were included in this meta-analysis. The result shows UTI increased the 28-day survival rate of septic patients, odds ratio (OR = 2.01, 95% CI [1.53, 2.64]. After the treatment with UTI, the APACHE II score (four studies dropped 4.72 further, mean = −4.72, 95% CI [−6.54, −2.91] (p<0.00001. The mean time of ICU stay (four studies in UTI group decreased 3.03 days further, mean = −3.03 [−6.99, 0.95] (p=0.14, and mechanical ventilation time (four studies decreased 2.05 days, mean = −1.81 [−2.96, −0.66] (p=0.002. 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.

    Full Text Available Background Acupuncture is a commonly used treatment option for the treatment of addictions such as alcohol, nicotine and drug dependence. We systematically reviewed and meta-analyzed the randomized controlled trials of acupuncture for the treatment of cocaine addiction. Methods Two reviewers independently searched 10 databases. Unpublished studies were sought using Clinicaltrials.gov, the UK National Research Register and contacting content experts. Eligible studies enrolled patients with the diagnosis of cocaine dependence of any duration or severity randomly allocated to either acupuncture or sham or other control. We excluded studies of acupuncture methods and trials enrolling patients with polysubstance use or dependence. We abstracted data on study methodology and outcomes. We pooled the studies providing biochemical confirmation of cocaine abstinence. Results Nine studies enrolling 1747 participants met inclusion criteria; 7 provided details for biochemical confirmation of cocaine abstinence. On average, trials lost 50% of enrolled participants (range 0–63%. The pooled odds ratio estimating the effect of acupuncture on cocaine abstinence at the last reported time-point was 0.76 (95% CI, 0.45 to 1.27, P = 0.30, I2 = 30%, Heterogeneity P = 0.19. Conclusion This systematic review and meta-analysis does not support the use of acupuncture for the treatment of cocaine dependence. However, most trials were hampered by large loss to follow up and the strength of the inference is consequently weakened.

    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.

    Drug-induced liver injury is the leading cause for more than 50 percent of cases of acute liver failure. This study was conducted on herbo-mineral formulation "Hepcon" to evaluate its hepatoprotective effects in drug induced hepatitis in experimental animals. The liver injury was introduced with over dosage of non steroidal anti-inflammatory drugs (NSAIDs) and carbon tetrachloride (CCl4). The herbo-mineral formulations "Hepcon" consist of Zingiber officinale, Piprum nigrum, Ammonium chloride and Arsenic trioxide (Hartal warqi). The aqueous extraction was administered to experimental animals. Thereafter their LFTs, IgG, and tissue pathology was studied. It was observed on the basis of biochemical and histopathological analysis that animals which were subjected to Hepcon became normal in 60 days whereas those as control group did not showed improvements and most of them died. It was concluded that the efficacy of Hepcon to treat liver injury caused by CCl4 and NSAIDs is very effective, and no side effects were noticed. PMID:24035958

    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. PMID:25886202

  2. Efficacy and prognostic analysis of chemoradiotherapy in patients with thoracic esophageal squamous carcinoma with cervical lymph nodal metastasis alone

    International Nuclear Information System (INIS)

    The prognostic factors of thoracic esophageal squamous carcinoma with cervical lymph nodal metastasis (CLNM) have not been specifically investigated. This study was performed to analyze the efficacy and prognostic factors of chemoradiotherapy for thoracic esophageal carcinoma with CLNM alone. From 2002 to 2011, 139 patients with inoperable esophageal cancer who underwent chemoradiotherapy at the Sun Yat-Sen University were retrospectively analyzed. Median radiation doses were 60 Gy (range: 50–68 Gy). Univariate and multivariate analyses were performed to compare overall survival (OS) and progression-free survival (PFS). The 1- and 3-year OS rates were 68.2% and 27.9%, respectively. The 1- and 3-year PFS rates were 51.9% and 20.1%, respectively. The multivariate analysis demonstrated that response to treatment, T stage, pathological grade, and laterality of cervical lymph nodal metastases were independent prognostic factors for thoracic esophageal carcinoma with CLNM. Concurrent chemoradiotherapy is an important and hopeful treatment option for patients with esophageal cancer with CLNM alone. Our study has revealed that response to treatment, T stage, pathological grade and laterality of cervical lymph nodal metastases are significant prognostic factors for long-term survival

    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

    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.

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.

    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.

    Genetic predisposition may contribute to the differences in drug-specific, class-specific or antidepressant-wide treatment resistance. Clinical studies with the genetic data are often limited in sample sizes. Drug response obtained from self-reports may offer an alternative approach to conduct a study with much larger sample size. Using the phenotype data collected from 23andMe 'Antidepressant Efficacy and Side Effects' survey and genotype data from 23andMe's research participants, we conducted genome-wide association study (GWAS) on subjects of European ancestry using four groups of phenotypes (a) non-treatment-resistant depression (n=7795) vs treatment-resistant depression (TRD, n=1311), (b) selective serotonin reuptake inhibitors (SSRI) responders (n=6348) vs non-responders (n=3340), (c) citalopram/escitalopram responders (n=2963) vs non-responders (n=2005), and (d) norepinephrine-dopamine reuptake inhibitor (NDRI, bupropion) responders (n=2675) vs non-responders (n=1861). Each of these subgroups was also compared with controls (n ~ 190 000). The most significant association was from bupropion responders vs non-responders analysis. Variant rs1908557 (P=2.6 × 10(-8), OR=1.35) passed the conventional genome-wide significance threshold (P=5 × 10(-8)) and was located within the intron of human spliced expressed sequence tags in chromosome 4. Gene sets associated with long-term depression, circadian rhythm and vascular endothelial growth factor (VEGF) pathway were enriched in the bupropion analysis. No single-nucleotide polymorphism passed genome-wide significance threshold in other analyses. The heritability estimates for each response group compared with controls were between 0.15 and 0.25, consistent with the known heritability for major depressive disorder. PMID:27622933

    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

    Full Text Available With the high number of incarcerated veterans with mental illness and substance dependence returning to the community annually, a significant need exists for technologies that will help them return to employment. This study evaluates three methods of assistance: (1 basic vocational services, (2 self-study of a vocational manual designed for formerly incarcerated veterans, and (3 a group led by vocational staff using the vocational manual. We evaluated 69 veterans to determine the number finding employment within 3 months after enrollment in the study. The group format was expected to be superior to self-study, and self-study was expected to be superior to basic services. Though the group format was found to be superior to both self-study and basic services, the results for self-study and basic services were statistically similar. Limitations and directions for future refinement are discussed.

    Decolorized (purified, low anthraquinone) whole leaf Aloe vera (L.) Burm. f. juice was administered at concentrations of 0%, 0.5%, 1% and 2% in the drinking water of F344Du rats for 3 months without any adverse effect. The no-observed-adverse-effect level (NOAEL) in this study was considered to be >2%w/v (>1845 mg/kg bodyweight/day for males and >2920 mg/kg bodyweight for females). The test material contained total anthraquinones at Aloe vera extracts tested in other studies have resulted in an increased incidence and severity of diarrhea and colon adenomas and carcinomas. The results of this study supports the assertion that the high levels of anthraquinone present in orally administered, non-purified whole leaf Aloe vera extract may be responsible for the adverse effects observed on the colon.

    Full Text Available Abstract Background Historically neurosurgeons have accepted head injured patients only in the presence of a mass lesion requiring surgical decompression. Underpinning this is an assumption that these patients have a better outcome than patients without a surgical lesion. This has meant that many patients without a surgical lesion have been managed locally in the referring hospital. However, there is now evidence that treatment of all head injured patients in a specialist centre leads to improved outcomes. Therefore, we have asked the question: does the presence of a surgical lesion imply better outcome from severe head injury? Results We prospectively recorded the Glasgow Outcome score (GOS, at 3 months, of all the severely head injured patients treated at our institution over a two and a half year period. Of 116 patients admitted with an initial Glasgow Coma Score (GCS of 8 or less, 58 had surgical lesions and 58 non-surgical head injuries. The two groups were well matched for presenting GCS and age. Overall our favourable outcome rate (GOS 4 and 5 at 3-months for the patients with a surgical lesion and for the non-surgical group were 47.3% and 46.6% respectively, with no significant difference between the two (P = 0.54. Conclusion The assumption in the past has always been that patients presenting in coma from traumatic diffuse brain injury will do worse than those that have a mass lesion amenable to surgical decompression. Our series would suggest that this is not the case and all severely head injured patients should expect similar outcome when cared for in a neuroscience centre.

    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.

  16. Combination of ultrasound-guided percutaneous microwave ablation and radioiodine therapy in benign thyroid disease. A 3-month follow-up study

    International Nuclear Information System (INIS)

    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.

    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

    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

Here, we sought to update the existing systematic review and meta-analysis of IL-1 RA in models of ischaemic stroke, published in 2009, to assess efficacy, the range of circumstances in which efficacy has been tested and whether the data appear to be confounded due to reported study quality and publication bias. We included 25 sources of data, 11 of which were additional to the original review. Overall, IL-1 RA reduced infarct volume by 36.2 % (95 % confidence interval 31.6-40.7, n = 76 comparisons from 1283 animals). Assessments for publication bias suggest 30 theoretically missing studies which reduce efficacy to 21.9 % (17.3-26.4). Efficacy was higher where IL-1 RA was administered directly into the ventricles rather than peripherally, and studies not reporting allocation concealment during the induction of ischaemia reported larger treatment effects. The preclinical data supporting IL-1 RA as a candidate therapy for ischaemic stroke have improved. The reporting of measures to reduce the risk of bias has improved substantially in this update, and studies now include the use of animals with relevant co-morbidities. PMID:27526101

    Despite B vitamin supplementation playing an important role in cognitive function, the exact effect remains unknown. The aim of this study was to systematically review and quantitatively synthesize the efficacy of treatment with vitamins B supplementation in slowing the rate of cognitive, behavioral, functional and global decline in individuals with MCI or AD. A systematic literature search in PubMed, EMBASE, International Pharmaceutical Abstracts, clinicaltrials. gov, the Cochrane Controlled Trials Register, the Cochrane Database of Systematic Reviews, and the Cochrane Cognitive Improvement Group specialized registry was conducted on April 2014, with no limit of date. Five trials met the eligibility criteria and were selected for this meta-analysis. Meta-analysis showed moderate beneficial effects of vitamins B supplementation on memory (SMD 0.60, 95% CI 0.20, 1.00), whereas no significant difference on general cognitive function (WMD -0.10, 95% CI -0.80, 0.59), executive function (SMD 0.05, 95% CI -0.11, 0.21) and attention (WMD -0.03, 95% CI -1.20, 1.14) were found in MCI patients. In addition, no significantly cognitive benefits on the Alzheimer's Disease Assessment Scale (ADAS-cog) (WMD 1.01, 95% CI -0.68, 2.70) and Mini Mental State Examination (MMSE) (WMD -0.22, 95% CI -1.00, 0.57), functional (SMD 0.13, 95% CI -0.05, 0.31), behavioral (SMD 0.04, 95% CI -0.16, 0.25) or global (WMD 0.07, 95% CI -0.48, 0.62) change were observed in AD patients. Collectively, weak evidence of benefits was observed for the domains of memory in patients with MCI. Nevertheless, future standard RCTs are still needed to determine whether it was still significant in larger populations. However, the data does not yet provide adequate evidence of an effect of vitamins B on general cognitive function, executive function and attention in people with MCI. Similarly, folic acid alone or vitamins B in combination are unable to stabilize or slow decline in cognition, function, behavior, and

    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

    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.

    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.

    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.

    Methotrexate (MTX), the most commonly used anti-rheumatic drug against RA, enters the cell via the action of the reduced folate carrier 1(RFC1). A major polymorphism of the RFC1 gene, 80G/A, has been reported to influence the activity of RFC1, resulting in variable intracellular MTX-polyglutamate (MTX-PG) levels. However, the association studies addressing the RFC1 80G/A polymorphism and MTX efficacy or toxicity in Rheumatoid arthritis (RA) has yielded conflicting results. In the present meta-analysis, we aimed to evaluate the association between the RFC1 80G/A polymorphism and MTX efficacy or toxicity in RA patients. A total 17 studies met our inclusion criteria. Among them, 12 studies with 2049 subjects reported the association between the RFC1 80G/A and MTX response, and 12 studies involving 2627 subjects were on MTX-related toxicity. Meta-analysis revealed significant association between RFC1 80G/A polymorphism and MTX efficacy (odds ratio (OR) for the A allele=1.29, 95% confidence interval (CI) 1.05-1.67, P=0.02; for AA genotype: OR=1.49, 95%CI 1.17-1.907, P=0.001). However, no association could be detected in the analysis of MTX-related toxicity. Stratification by ethnic population also indicated an association between this polymorphism and MTX efficacy in Asian group (P=0.002 for A allele; P=0.003 for AA genotype), but not in the Caucasian group (P=0.15 for A allele; P=0.05 for AA genotype). In both Asian and Caucasian sub-groups, no influence of the RFC1 80G/A polymorphism on MTX toxicity can be detected. In conclusion, the RFC1 G80A polymorphism is associated with responsiveness to MTX therapy, but may not be associated with MTX toxicity in RA patients. PMID:27233001

  1. 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.

    Warfarin dosage estimation using the pharmacogenetic algorithms has been shown to improve the quality of anticoagulation control in patients with atrial fibrillation. We sought to assess the genetic, demographic and clinical factors that determine the quality of anticoagulation in patients following aortic valve replacement (AVR). We studied 200 consecutive patients (130 men) aged 63 ± 12.3 years, undergoing AVR, in whom warfarin dose was established using a pharmacogenetic algorithm. The quality of anticoagulation within the first 3 months since surgery was expressed as the time of international normalized ratio (INR) in the therapeutic range (TTR). The median TTR in the entire cohort was 59.6% (interquartile range, 38.7 - 82.7). Ninety-nine (49.5%) patients with TTR ≥ 60% did not differ from those with poor anticoagulation control (TTR modification and therapy. Possession of CYP2C9*2 and/or CYP2C9*3 allele variants is associated with lower TTR values and warfarin dose variations in AVR patients, the latter affected also by VKORC1 c.-1693G>A polymorphism.

    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.

    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.

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.

    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.

    The purpose of this study was to examine learning, short-term memory and general development including cognitive, motor, and language domains in infants with Complex Congenital Heart Defects (CCDH). Ten infants with CCHD (4 males, 6 females) and 14 infants with typical development (TD) were examined at 3 months of age. The mobile paradigm, where an infant's leg is tethered to an overhead mobile, was used to evaluate learning and short-term memory. The Bayley Scales of Infant Development 3rd edition (Bayley-III) was used to evaluate general development in cognitive, motor, and language domains. Infants with CCHD and infants with TD both showed learning with significant increase in kicking rate (pshort-term memory (p=0.017) in the mobile paradigm. There were no differences on cognitive, motor, and language development between infants with CCHD and infants with TD on the Bayley-III. Early assessment is necessary to guide targeted treatment in infants with CCHD. One-time assessment may fail to detect potential cognitive impairments during early infancy in infants with CCHD. Supportive intervention programs for infants with CCHD that focuses on enhancing short-term memory are recommended. PMID:25919428

    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.

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.

    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

    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

    Background Several studies found that vitamin D3 might alter glucose metabolism,protect kidney from injury and even proposed the mechanisms.But results from previous studies have been conflicting.The aim of this study was to evaluate the efficacy and safety of vitamin D3 in patients with diabetic nephropathy.The underlying mechanism of vitamin D3 decreasing proteinuria is also discussed.Methods We conducted a search of English and Chinese articles using database of Pubmed,Embase,Sinomed,CNKI,Wanfang and clinical trial register centers,for randomized controlled trials of vitamin D3 in diabetic nephropathy patients.Two reviewers performed independently.Meta-analysis was used when studies were homogeneous enough.Results Twenty studies,including 1 497 patients with diabetic nephropathy,were involved in this systemic review.Vitamin D3-treated patients with diabetic nephropathy had a statistically significant reduction in 24-hour proteinuria (weighted mean difference-0.44,95% CI-0.54 to-0.34,Z=8.80,P <0.000 01) and urine albumin/creatine ratio (standardized mean difference-0.29,95% CI-0.48 to-0.10,Z=2.96,P=0.003).But vitamin D3 supplementation did not significantly reduce blood pressure and hemoglobin A1c compared with control group.The potential mechanisms about the renal protection of vitamin D3,including the inhibition of rennin-angiotensin system,the protection of kidney from inflammation,fibrosis and the structure change of kidney are discussed.In addition,vitamin D3 did not significantly increase the incidence of adverse effects,including total adverse effects,gastrointestinal adverse effects and fluctuation of blood pressure.Conclusions Vitamin D3 can ameliorate proteinuria and protect kidney from injury in patients with diabetic nephropathy.This renoprotective effect is independent of blood pressure and glucose reduction.And it does not increase any adverse effects than control,even in combination therapy with angiotensin converting enzyme inhibitors

  16. Safety and efficacy of stereotactic body radiotherapy as primary treatment for vertebral metastases: a multi-institutional analysis

    International Nuclear Information System (INIS)

    To evaluate patient selection criteria, methodology, safety and clinical outcomes of stereotactic body radiotherapy (SBRT) for treatment of vertebral metastases. Eight centers from the United States (n = 5), Canada (n = 2) and Germany (n = 1) participated in the retrospective study and analyzed 301 patients with 387 vertebral metastases. No patient had been exposed to prior radiation at the treatment site. All patients were treated with linac-based SBRT using cone-beam CT image-guidance and online correction of set-up errors in six degrees of freedom. 387 spinal metastases were treated and the median follow-up was 11.8 months. The median number of consecutive vertebrae treated in a single volume was one (range, 1-6), and the median total dose was 24 Gy (range 8-60 Gy) in 3 fractions (range 1-20). The median EQD210 was 38 Gy (range 12-81 Gy). Median overall survival (OS) was 19.5 months and local tumor control (LC) at two years was 83.9%. On multivariate analysis for OS, male sex (p < 0.001; HR = 0.44), performance status <90 (p < 0.001; HR = 0.46), presence of visceral metastases (p = 0.007; HR = 0.50), uncontrolled systemic disease (p = 0.007; HR = 0.45), >1 vertebra treated with SBRT (p = 0.04; HR = 0.62) were correlated with worse outcomes. For LC, an interval between primary diagnosis of cancer and SBRT of ≤30 months (p = 0.01; HR = 0.27) and histology of primary disease (NSCLC, renal cell cancer, melanoma, other) (p = 0.01; HR = 0.21) were correlated with worse LC. Vertebral compression fractures progressed and developed de novo in 4.1% and 3.6%, respectively. Other adverse events were rare and no radiation induced myelopathy reported. This multi-institutional cohort study reports high rates of efficacy with spine SBRT. At this time the optimal fractionation within high dose practice is unknown

    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.

    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 < .00001), whereas meta-analysis of four studies showed a decrease of WOMAC with turmeric/curcumin treatment (mean difference: -15.36 [-26.9, -3.77]; P = .009). Furthermore, there was no significant mean difference in PVAS between turmeric/curcumin and pain medicine in meta-analysis of five studies. Eight RCTs included in the review exhibited low to moderate risk of bias. There was no publication bias in the meta-analysis. In conclusion, these RCTs provide scientific evidence that supports the efficacy of turmeric extract (about 1000 mg/day of curcumin) in the treatment of arthritis. However, the total number of RCTs included in the analysis, the total sample size, and the methodological quality of the primary studies were not sufficient to draw definitive conclusions. Thus, more rigorous and larger studies are needed to confirm the therapeutic efficacy of turmeric for arthritis. PMID:27533649

    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

    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. This information allows a physician to

    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. PMID:27442675

    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.

    Background 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. Method We present a systematic review, quality assessment and meta-analysis of the preclinical evidence for renal IPoC, and identify factors which modify its efficacy. Results 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. Conclusion 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. PMID:26963819

    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.

    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

    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.

    The prevalence of hyperuricemia and gout has been increasing, but the comparative effectiveness and safety of different treatments remain uncertain. We aimed to compare the effectiveness and safety of different treatments for hyperuricemia using network meta-analysis methodology. We systematically reviewed fifteen randomized controlled trials (involving 7,246 patients through January 2016) that compared the effects of different urate-lowering drugs (allopurinol, benzbromarone, febuxostat, pegloticase and probenecid) on hyperuricemia. Drug efficacy and safety, as outcomes, were measured by whether the target level of serum urate acid was achieved and whether any adverse events occurred, respectively. We derived pooled effect sizes expressed as odds ratios (ORs) and 95% confidence intervals (CIs). The efficacy and safety of the drugs were ranked by cumulative ranking probabilities. Our findings show that febuxostat, benzbromarone, probenecid, pegloticase, and allopurinol were all highly effective at reducing the risk of hyperuricemia compared to placebo. Febuxostat had the best efficacy and safety compared to the other drugs. Furthermore, febuxostat 120 mg QD was more effective at achieving urate-lowering targets (OR: 0.17, 95% CI: 0.12-0.24) and safer (OR: 0.72, 95% CI: 0.56-0.91) than allopurinol. PMID:27605442

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    The primary aims of this study were to assess the analgesic efficacy and adverse effects of single-dose oral tramadol plus acetaminophen in acute postoperative pain and to use meta-analysis to demonstrate the efficacy of the combination drug compared with its components. Individual patient data from seven randomized, double blind, placebo controlled trials of tramadol plus acetaminophen were supplied for analysis by the R.W. Johnson Pharmaceutical Research Institute, Raritan, New Jersey, USA. All trials used identical methods and assessed single-dose oral tramadol (75 mg or 112.5 mg) plus acetaminophen (650 mg or 975 mg) in adult patients with moderate or severe postoperative pain. Summed pain intensity and pain relief data over six and eight hours and global evaluations of treatment effect after eight hours were extracted. Number-needed-to-treat (NNT) for one patient to obtain at least 50% pain relief was calculated. NNTs derived from pain relief data were compared with those derived from pain intensity data and global evaluations. Information on adverse effects was collected. Combination analgesics (tramadol plus acetaminophen) had significantly lower (better) NNTs than the components alone, and comparable efficacy to ibuprofen 400 mg. This could be shown for dental but not postsurgical pain, because more patients were available for the former. Adverse effects were similar for the combination drugs and the opioid component alone. Common adverse effects were dizziness, drowsiness, nausea, vomiting, and headache. In sum, this meta-analysis demonstrated analgesic superiority of the combination drug over its components, without additional toxicity. PMID:11844632

    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.

    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

    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

    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

    Chemotherapy-induced alopecia (CIA) is a highly distressing event for cancer patients, and hence, we here aimed to assess the efficacy of various interventions in the prevention of CIA. We searched PubMed, EMBASE and the Cochrane Library, from June 20, 2013 through August 31, 2013. Two of the authors independently reviewed and selected clinical trials that reported the efficacy of any intervention for prevention of CIA compared with that of controls. Two authors extracted data independently on dichotomized outcome in terms of CIA occurrence. Relative risks (RRs) and 95% confidential intervals (CIs) were calculated for efficacy of CIA prevention by using random-effect or fixed-effect models. Out of 691 articles retrieved, a total of eight randomized controlled trials and nine controlled clinical trials involving 1,098 participants (616 interventions and 482 controls), were included in the final analyses. Scalp cooling, scalp compression, a combination of cooling and compression, topical minoxidil and Panicum miliaceum were used as interventions. The participants were mainly breast cancer patients receiving doxorubicin- or epirubicin-containing chemotherapy. Scalp cooling, which is the most popular preventive method, significantly reduced the risk of CIA (RR = 0.38, 95% CI = 0.32-0.45), whereas topical 2% minoxidil and other interventions did not significantly reduce the risk of CIA. No serious adverse effects associated with scalp cooling were reported. Our results suggest that scalp cooling can prevent CIA in patients receiving chemotherapy. However, the long-term safety of scalp cooling should be confirmed in further studies. PMID:25081068

    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. PMID:25705787

    Treatment of nasopharyngeal carcinoma (NPC) can be improved by early detection of the disease as treatment outcome worsens with disease's progression. This can be achieved with a mass screening program using Epstein Barr virus (EBV) serology and nasopharyngoscopy. The efficacy of any screening strategy should be evaluated before putting it into practice. Such evaluation is ideally performed with simulation as time and cost often preclude the evaluation by randomized trial. This study simulated and compared the outcomes of 4 screening strategies over a period of 12 years: (A) Annual screening, (B) biennial screening, (C) triennial screening, and (D) triennial screening for participants tested EBV negative and annual screening once the participants are tested EBV positive. Progression of the disease was divided into 4 phases and calculated by applying Markov chain model. Parameters of the transition matrix and probabilities were estimated using data from previous screening results of 1,072 family members of NPC patients. The early detection rates with strategies A, B, C and D are 88, 79, 71 and 87% respectively. The 5-year overall survival with screening is 10-12% higher than that without and is the highest with strategies A and D. Strategy D, however, requires only 64% screening tests compared with strategy A and has almost identical resultant disease stage distribution to strategy A. We concluded that strategy D offered the highest efficacy for NPC screening of family members of NPC patients among the four strategies studied. PMID:21052850

    2011-12-01

    Low participation and performance in science, technology, engineering, and mathematics (STEM) fields by U.S. citizens are widely recognized as major problems with substantial economic, political, and social ramifications. Studies of collegiate interventions designed to broaden participation in STEM fields suggest that participation in undergraduate research is a key program component that enhances such student outcomes as undergraduate GPA, graduation, persistence in a STEM major, and graduate school enrollment. However, little is known about the mechanisms that are responsible for these positive effects. The current study hypothesizes that undergraduate research participation increases scientific self-efficacy and scientific research proficiency. This hypothesis was tested using data obtained from a survey of minority students from several STEM intervention programs that offer undergraduate research opportunities. Students were surveyed both prior to and following the summer of 2010. Factor analysis was used to examine the factor structure of participants' responses on scientific self-efficacy and scientific research proficiency scales. Difference-in-difference analysis was then applied to the resulting factor score differences to estimate the relationship of summer research participation with scientific self-efficacy and scientific research proficiency. Factor analytic results replicate and further validate previous findings of a general scientific self-efficacy construct (Schultz, 2008). While the factor analytic results for the exploratory scientific research proficiency scale suggest that it was also a measureable construct, the factor structure was not generalizable over time. Potential reasons for the lack of generalizability validity for the scientific research proficiency scale are explored and recommendations for emerging scales are provided. Recent restructuring attempts within federal science agencies threaten the future of STEM intervention programs

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.

Seven of 15 randomized, placebo-controlled trials in patients with dementia identified by database searches met all our selection criteria and were included in the meta-analysis. In these trials, patients were treated with 120 mg or 240 mg per day of the defined extract EGb 761 or placebo. Efficacy was assessed using validated tests and rating scales for the cognitive domain, the functional domain (activities of daily living, and global assessment. Tolerability was evaluated by risk differences based on incidences of adverse events and premature discontinuation rates. Of 2,684 outpatients randomized to receive treatment for 22–26 weeks, 2,625 represented the full analysis sets (1,396 for EGb 761 and 1,229 for placebo. Standardized mean differences for change in cognition (-0.52; 95% confidence interval [CI] -0.98, -0.05; P=0.03, activities of daily living (-0.44; 95% CI -0.68, -0.19; P<0.001, and global rating (-0.52; 95% CI -0.92, -0.12; P=0.01 significantly favored EGb 761 compared with placebo. Statistically significant superiority of EGb 761 over placebo was confirmed by responder analyses as well as for patients suffering from dementia with neuropsychiatric symptoms. Treatment-associated risks in terms of relative risks of adverse events and premature withdrawal rates did not differ noticeably between the two treatment groups. In conclusion, meta-analyses confirmed the efficacy and good tolerability of Ginkgo biloba extract EGb 761 in patients with dementia.

Methods 22 RCTs were included in the AD analysis that evaluated: indacaterol 75 μg (n = 2 studies, indacaterol 150 μg n = 5 (i.e. salmeterol 50 μg (n = 5, indacaterol 300 μg (n = 2, tiotropium 18 μg (n = 10, salmeterol 50 μg (n = 7, and formoterol 12 μg (n = 4. All of the studies except for one head-to-head comparison (tiotropium vs. salmeterol were placebo controlled. Outcomes of interest were trough forced expiratory volume in 1 second (FEV1 and St. George’s Respiratory Questionnaire (SGRQ total score at week 12. The AD from all trials was analysed simultaneously using a Bayesian network meta-analysis (NMA and relative treatment effects between all regimens were obtained. In a separate analysis, the IPD available from the 6 indacaterol RCTs was analysed in a NMA. Treatment-by-covariate interactions were included in both analyses to improve similarity of the trials. Results All interventions compared were more efficacious than placebo regarding FEV1 at 12 weeks. Indacaterol 75 μg is expected to result in a comparable FEV1 at 12 weeks to tiotropium and salmeterol based on both IPD and AD analyses. In comparison to formoterol, the IPD and AD results indicate indacaterol 75 μg is more efficacious (IPD = 0.07 L difference; 95%Credible Interval (CrI 0.02 to 0.11; AD = 0.05 L difference; 95%CrI 0.01; 0.09. In terms of SGRQ total score at 12 weeks, indacaterol 75 μg and formoterol were more efficacious than

    Direct oral anticoagulants simplify venous thromboembolism (VTE) treatment by obviating the need for coagulation monitoring. Nonetheless, renal function, body weight and P-glycoprotein inhibitors influence drug levels. The objective of this analysis was to determine whether reduction in edoxaban dose based on clinical criteria avoids excess drug exposure and preserves efficacy and safety in the Hokusai-VTE study. After initial heparin, patients received edoxaban or warfarin for 3-12 months. Edoxaban was given once daily at a dose of 60 mg, which was reduced to 30 mg in patients with a creatinine clearance of 30-50 ml/minute, body weight ≤60 kg or receiving certain P-glycoprotein inhibitors. The primary efficacy outcome was recurrent VTE and the principal safety outcome was major or clinically relevant non-major bleeding. A total of 8292 patients with acute VTE were randomised, 733 and 719 patients in the edoxaban and warfarin groups met the criteria for dose reduction. These patients were older, more often female or Asian and had more extensive VTE. Edoxaban levels were lower in the 30 mg edoxaban group. Rates of recurrent VTE and bleeding with the 30 mg and 60 mg edoxaban dose were comparable: VTE rates were 3.0 % and 3.2 % and clinically relevant bleeding rates were 7.9 % and 8.6 %, respectively. Rates of recurrent VTE and bleeding in the warfarin-treated patients meeting the criteria for dose reduction were 4.2 % and 12.8 %, respectively. The reduced dose edoxaban regimen maintained efficacy and safety compared with the 60 mg dose but was safer than warfarin in patients meeting the criteria for dose reduction. PMID:27440518

    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

We reviewed their evidence by searching MEDLINE®, Embase, The Cochrane Library, and the International Pharmaceutical Abstracts from 1980 through 2007 (July for placebo-controlled and comparative trials assessing cognition, function, behavior, global change, and safety. Thirty-three articles on 26 studies were included in the review. Meta-analyses of placebo-controlled data support the drugs’ modest overall benefits for stabilizing or slowing decline in cognition, function, behavior, and clinical global change. Three open-label trials and one double-blind randomized trial directly compared donepezil with galantamine and rivastigmine. Results are conflicting; two studies suggest no differences in efficacy between compared drugs, while one study found donepezil to be more efficacious than galantamine, and one study found rivastigmine to be more efficacious than donepezil. Adjusted indirect comparison of placebo-controlled data did not find statistically significant differences among drugs with regard to cognition, but found the relative risk of global response to be better with donepezil and rivastigmine compared with galantamine (relative risk = 1.63 and 1.42, respectively. Indirect comparisons also favored donepezil over galantamine with regard to behavior. Across trials, the incidence of adverse events was generally lowest for donepezil and highest for rivastigmine.Keywords: Alzheimer

    The NCI60 database is the largest available collection of compounds with measured anti-cancer activity. The strengths and limitations for using the NCI60 database as a source of new anti-cancer agents are explored and discussed in relation to previous studies. We selected a sub-set of 2333...... and in a data set of expression profiles of 1901 genes for the corresponding tumor cell lines. Five clusters were identified based on the gene expression data using self-organizing maps (SOM), comprising leukemia, melanoma, ovarian and prostate, basal breast, and luminal breast cancer cells, respectively....... The strong difference in gene expression between basal and luminal breast cancer cells was reflected clearly in the chemosensitivity data. Although most compounds in the data set were of low potency, high efficacy compounds that showed specificity with respect to tissue of origin could be found. Furthermore...

    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

    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.

  20. Measurement of circulating transcripts and gene cluster analysis predicts and defines therapeutic efficacy of peptide receptor radionuclide therapy (PRRT) in neuroendocrine tumors

    International Nuclear Information System (INIS)

    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 177Lu-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 18FDG 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 %, χ2 = 27.4; p = 1.2 x 10-7) 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 < 0.004) for predicting

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.

    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.

    Full Text Available PURPOSE: Oral fluoropyrimidine (S-1, capecitabine has been considered as an important part of various regimens. 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.

    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.

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

    Full Text Available The objective of this study was to analyze the level of evidence regarding the efficacy, effectiveness and safety of over-the-counter (OTC cough medications registered in Brazil. The National Health Surveillance Agency database was used to identify the drugs. Clinical trials, systematic reviews, meta-analyses, and studies on safety were searched on the Medline baseline, the Cochrane Library and SIETES (System of Essential Information in Therapeutics and Health; database in Spanish. Most drugs (62.5% were sold as a fixed-dose combination of two or more drugs. Randomized clinical trials were found for only three drugs: bromhexine, dextromethorphan and guaifenesin. No clinical trials were found for fixed-dose combinations. Systematic reviews on Cochrane did not report any evidence in favor of or against the effectiveness of cough drugs. Efficacy is also unclear, especially regarding fixed-dose combinations. The evidence for the efficacy of OTC cough medications available in Brazil is poor due to the lack of quality studies. Pharmacovigilance of OTC cough medications should be encouraged.O objetivo deste trabalho foi analisar o nível de evidências sobre a eficácia, a efetividade e a segurança dos medicamentos para tosse registrados no Brasil.

    The aesthetic market offers various radiofrequency treatments for the reduction of wrinkles and rhytids. Even though this not an uncommon aesthetic therapy, there is considerable lack of clinical evidence on the various energy delivery systems available (unipolar, bipolar, tripolar, multipolar, etc.). The purpose of this study was to demonstrate the efficacy of a monopolar radiofrequency device (Exilis Elite, BTL Industries Inc., Boston, MA, USA) on the skin collagen in an animal model. The study treatment was done on the abdominal area of the potbellied Vietnamese mini pigs in the Veterinary Research Institute facility. All pigs were treated once per week for 4 weeks. The treatment area was sized 20 × 10 cm. The surface temperature was kept in the therapeutic interval from 39 °C to 43 °C and the therapy lasted for 10 minutes after reaching the therapeutic temperature. Biopsy samples were taken before the therapy and at the 3-month follow-up. The histology samples were stained and magnified (×400) before computer processing. The collagen volume was calculated using the stereological analysis and the data were statistically processed (using the nonparametric two-sample t-test). The collagen content tissue increased from average of 9.0% before the therapy up to 25.9% after the 3-month follow-up period. The statistical comparison of 54 samples taken before and after the treatment acknowledged the significant difference (p = 0.018). The stereological analysis proved large-scale improvement of collagen in the treated area. We have observed that the monopolar radiofrequency therapy significantly increases collagen remodeling.

    The RV144 clinical trial of a prime/boost immunizing regimen using recombinant canary pox (ALVAC-HIV) and two gp120 proteins (AIDSVAX B and E) was previously shown to have a 31.2% efficacy rate. Plasma specimens from vaccine and placebo recipients were used in an extensive set of assays to identify correlates of HIV-1 infection risk. Of six primary variables that were studied, only one displayed a significant inverse correlation with risk of infection: the antibody (Ab) response to a fusion protein containing the V1 and V2 regions of gp120 (gp70-V1V2). This finding prompted a thorough examination of the results generated with the complete panel of 13 assays measuring various V2 Abs in the stored plasma used in the initial pilot studies and those used in the subsequent case-control study. The studies revealed that the ALVAC-HIV/AIDSVAX vaccine induced V2-specific Abs that cross-react with multiple HIV-1 subgroups and recognize both conformational and linear epitopes. The conformational epitope was present on gp70-V1V2, while the predominant linear V2 epitope mapped to residues 165-178, immediately N-terminal to the putative α4β7 binding motif in the mid-loop region of V2. Odds ratios (ORs) were calculated to compare the risk of infection with data from 12 V2 assays, and in 11 of these, the ORs were ≤1, reaching statistical significance for two of the variables: Ab responses to gp70-V1V2 and to overlapping V2 linear peptides. It remains to be determined whether anti-V2 Ab responses were directly responsible for the reduced infection rate in RV144 and whether anti-V2 Abs will prove to be important with other candidate HIV vaccines that show efficacy, however, the results support continued dissection of Ab responses to the V2 region which may illuminate mechanisms of protection from HIV-1 infection and may facilitate the development of an effective HIV-1 vaccine.

    Full Text Available Objectives. This study observes therapeutic efficacy of uterine artery embolization combined with MTX infusion which terminates cesarean scar pregnancy (CSP and induces three factors which probably relate to failure. Methods. Twenty-three CSP patients were treated with combined uterine artery MTX infusion and embolization. Among them six patients with severe hemorrhage were immediately treated with interventional operation. Clinical effects were estimated by symptoms, serum -hCG, ultrasound, and MR. Results. Interventional treatments were technologically successful in 22 patients except one. Immediate hemostasis was achieved in all 6 patients with massive colporrhagia. No occurrence of infection and uterine necrosis was observed, but 12 women suffered abdominal pains. Nineteen patients’ uteri were preserved, whereas four underwent hysterectomy eventually. Conclusions. Transcatheter arterial chemoembolization is effective to treat high-risk CSP in preference to hysterectomy. To achieve more successful outcomes, three factors should be highlighted: adequate MTX dosage, appropriate embolic material, and complete embolization of target arteries that supply blood to embryo in the scar.

    Concurrent chemoradiotherapy has proven to be more effective on patients with advanced cervical cancer than radiotherapy alone. Although cisplatin has been recommended to be the standard agent in chemotherapy, it has some limitations in clinical use because of its strong side effects. Moreover, the optimal chemotherapy regimen remains unclear. A comprehensive electronic search was conducted via the Internet retrieval system to identify eligible trials. The ending points included response, overall survival (OS), local recurrent, and distant metastasis rates. Odds ratios and 95% confidence interval were calculated to compare the effects. Fifteen trials with 1142 patients were eligible. With regard to the response rate, only nedaplatin showed a significant improvement compared with cisplatin. Docetaxel, pacitaxel, fluoropyrimidine, paclitaxel liposome, and irinotecan did not show any advantages. When targeted on OS or local recurrent rate, no significant advantage was found when these single-drug regimens were compared with cisplatin. However, when aimed at distant metastasis rate, fluoropyrimidine showed a disadvantage to cisplatin, whereas others showed equal efficacy. Nedaplatin, docetaxel, pacitaxel, and fluoropyrimidine showed a better effect on reducing chemotherapy toxicity than cisplatin. Single-drug chemotherapy concurrent with radiotherapy, except for nedaplatin, may have no advantage on clinical outcomes when compared with cisplatin but showed a better effect on reducing chemotherapy toxicity, which could be used as an alternative to patients who can not tolerate the side effects of cisplatin. Nedaplatin is also effective and safe, and may be highly valuable in clinical applications. PMID:26309518

    The efficacy, toxicity, and mechanism of effect of intravenous Anti-D (Winrho) were studied in 43 Rh+ patients with immune thrombocytopenia purpura (ITP) who had not undergone splenectomy and in three already splenectomized patients. The mean platelet increase for the 43 nonsplenectomized patients was 95,000/microL (median 43,000/microL). Children had greater acute platelet responses than did adults. Human immunodeficiency virus status and duration of thrombocytopenia did not affect response. Maintenance treatment was given to patients as needed: the average interval between infusions was 24 days. The three splenectomized patients had no platelet response whatsoever. Toxicity was minimal; infusions were completed in less than 5 minutes. The generally accepted mechanism of effect of Anti-D has been Fc receptor blockade by substitution of antibody-coated red blood cells for antibody-coated platelets. Evidence is presented suggesting that the effect of IV Anti-D is not limited to Fc receptor blockade, including: (1) no correlation of parameters of hemolysis with platelet increase; (2) a 48- to 72-hour delay before platelet increase; (3) a tendency of the change in monocyte Fc receptor I expression to correlate with platelet increase; and (4) increased in vitro production of antibodies to sheep red blood cells following IV Anti-D infusion.

    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.

    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.

    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.

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

    Full Text Available Abstract Background Praziquantel has been used as first-line drug for chemotherapy of schistosomiasis since 1984. Besides praziquantel, artemether and artesunate have also been used for the control of this infectious disease since late 1990s. In this article, we conducted a systematic review and meta-analysis to evaluate the antischistosomal efficacy of different medication strategies including monotherapy or combination therapies of these drugs. Results A number of 52 trials from 38 articles published in peer-reviewed journals before July 2011 were selected for analysis after searching the following literature databases: the Cochrane Library, PubMed/Medline, ISI Web of Science, Chinese Biomedicine Literature Database, and China National Knowledge Infrastructure. Our meta-analyses showed that a dosage of 30-60 mg/kg praziquantel compared with placebo produced a protection rate of about 76% (95% CI: 67%-83% for treating human schistosomiasis, which varied from 70% to 76% with no significant differences among the subspecies S. haematobium, S. japonicum or S. mansoni. Protection rates were higher when praziquantel doses were elevated, as concluded from the nRCTs results: the protection rate of praziquantel at 40 mg/kg was 52% (95% CI: 49%-55%, and it increased to 91% (95% CI: 88%-92% when the dosages were elevated to 60/80/100 mg/kg divided two or more doses. Multiple doses of artemether or artesunate over 1- or 2-week intervals resulted in protection rates of 65% to 97% for preventing schistosomiasis, and increased doses and shorter medication intervals improved their efficacies. Praziquantel and artemisinin derivatives (artemether or artesunate in combination resulted in a higher protection rate of 84% (95% CI: 64%-91% than praziquantel monotherapy for treatment. praziquantel and artesunate in combination had a great protection rate of 96% (95% CI: 78%-99% for preventing schistosomes infection. Conclusions According to the results, praziquantel

    Objective Axitinib is a potent and selective second-generation inhibitor of vascular endothelial growth factor receptors 1, 2 and 3. The efficacy and safety of axitinib in Japanese patients with metastatic renal cell carcinoma were evaluated. Methods A subgroup analysis was conducted in Japanese patients enrolled in the randomized Phase III trial of axitinib versus sorafenib after failure of one prior systemic therapy for metastatic renal cell carcinoma. Results Twenty-five (of 361) and 29 (of 362) patients randomized to the axitinib and sorafenib arms, respectively, were Japanese and included in this analysis. Median progression-free survival in Japanese patients was 12.1 months (95% confidence interval 8.6 to not estimable) for axitinib and 4.9 months (95% confidence interval 2.8–6.6) for sorafenib (hazard ratio 0.390; 95% confidence interval 0.130–1.173; stratified one-sided P = 0.0401). The objective response rate was 52.0% for axitinib and 3.4% for sorafenib (P = 0.0001). The common all-causality adverse events (all grades) in Japanese patients were dysphonia (68%), hypertension (64%), hand–foot syndrome (64%) and diarrhea (56%) for axitinib, and hand–foot syndrome (86%), hypertension (62%) and diarrhea (52%) for sorafenib. The safety profiles of axitinib and sorafenib in Japanese patients were generally similar to those observed in the overall population, with the exceptions of higher incidences of hypertension, dysphonia, hand–foot syndrome, hypothyroidism and stomatitis. Conclusions Axitinib is efficacious and well tolerated in Japanese patients with previously treated metastatic renal cell carcinoma, consistent with the results in the overall population, providing a new targeted therapy for these Japanese patients.

    A growing number of patients with chronic artery disease suffer from angina, despite the optimal medical management (ie, β-blockers, calcium channel blockers, and long-acting nitrates) and revascularization. Currently, enhanced external counterpulsation (EECP) therapy has been verified as a noninvasive, safe therapy for refractory angina. The study was designed to evaluate the efficacy of EECP in patients with chronic refractory angina according to Canadian Cardiovascular Society (CCS) angina class.We identified systematic literature through MEDLINE, EMBASE, the Cochrane Clinical Trials Register Database, and the ClinicalTrials. gov Website from 1990 to 2015. Studies were considered eligible if they were prospective and reported data on CCS class before and after EECP treatment. Meta-analysis was performed to assess the efficacy of EECP therapy by at least 1 CCS angina class improvement, and proportion along with the 95% confidence interval (CI) was calculated. Statistical heterogeneity was calculated by I statistic and the Q statistic. Sensitivity analysis was addressed to test the influence of trials on the overall pooled results. Subgroup analysis was applied to explore potential reasons for heterogeneity.Eighteen studies were enrolled in our meta-analysis. Pooled analysis showed 85% of patients underwent EECP had a reduction by at least one CCS class (95%CI 0.81-0.88, I = 58.5%, P < 0.001). The proportion of patients enrolled at primarily different studies with chronic heart failure (CHF) improved by at least 1 CCS class was about 84% after EECP (95%CI 0.81-0.88, I = 32.7%, P = 0.1668). After 3 large studies were excluded, the pooled proportion was 82% (95%CI 0.79-0.86, I = 18%, P = 0.2528). Funnel plot indicated that some asymmetry while the Begg and Egger bias statistic showed no publication bias (P = 0.1495 and 0.2859, respectively).Our study confirmed that EECP provided an effective treatment for patients who were unresponsive to medical management and

    Full Text Available BACKGROUND: Pharmacotherapy may represent a potential means to limit the expansion rate of abdominal aortic aneurysms (AAAs. Studies evaluating the efficacy of different pharmacological agents to slow down human AAA-expansion rates have been performed, but they have never been systematically reviewed or summarized. METHODS AND FINDINGS: Two independent reviewers identified studies and selected randomized trials and prospective cohort studies comparing the growth rate of AAA in patients with pharmacotherapy vs. no pharmacotherapy. We extracted information on study interventions, baseline characteristics, methodological quality, and AAA growth rate differences (in mm/year. Fourteen prospective studies met eligibility criteria. Five cohort studies raised the possibility of benefit of beta-blockers [pooled growth rate difference: -0.62 mm/year, (95%CI, -1.00 to -0.24], but this was not confirmed in three beta-blocker RCTs [pooled RCT growth rate difference: -0.05 mm/year (-0.16 to 0.05]. Statins have been evaluated in two cohort studies that yield a pooled growth rate difference of -2.97 (-5.83 to -0.11. Doxycycline and roxithromycin have been evaluated in two RCTs that suggest possible benefit [pooled RCT growth rate difference: -1.32 mm/year (-2.89 to 0.25]. Studies assessing NSAIDs, diuretics, calcium channel blockers and ACE inhibitors, meanwhile, did not find statistically significant differences. CONCLUSIONS: Beta-blockers do not appear to significantly reduce the growth rate of AAAs. Statins and other anti-inflammatory agents appear to hold promise for decreasing the expansion rate of AAA, but need further evaluation before definitive recommendations can be made.

    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.

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

  12. Feasibility and efficacy of chemoradiotherapy for elderly patients with locoregionally advanced nasopharyngeal carcinoma: results from a matched cohort analysis

    International Nuclear Information System (INIS)

    To clarify the feasibility and efficacy of chemoradiotherapy (CRT) in elderly (age≥65 years) patients with locoregionally advanced nasopharyngeal carcinoma (NPC). From January 2000 to December 2006, 101 newly diagnosed elderly non-metastatic NPC patients (age≥65 years) who received cisplatin 3-weekly or weekly concurrent CRT with/without sequential chemotherapy were recruited. Each patient from the CRT group was matched to another patient treated with radiotherapy (RT) alone based on age, gender, pathological type, performance status, overall stage, stage method, Adult Comorbidity Evaluation-27 (ACE-27) score and RT technique, from the same institute and time period. We also recruited 101 young patients (age<65 years) as the referent group, which had been matched to the CRT group based on patient characteristics and treatment parameters. Treatment tolerability and toxicity were clarified, and treatment outcomes were calculated and compared among groups. CRT was feasible in elderly NPC patients, while a concurrent regimen of weekly cisplatin was more tolerable. Grade≥3 acute toxicity in CRT group was similar with referent group, although it was significantly higher than the RT alone group (65.3% vs. 43.6%, P=0.002). Furthermore, patients with ACE-27 score≥2 in the CRT group had significantly higher severe acute toxicity and dose reduction. Survival was poorer in elderly patients than the referent group. Compared to RT alone, CRT significantly improved the 5-year overall survival (OS: 54.6% vs. 39.3%, P=0.009), cancer-specific survival (CSS: 56.6% vs. 42.7%, P=0.022), disease-free survival (DFS: 51.6% vs. 30.2%, P=0.028) and locoregional relapse-free survival (LRRFS: 78.4% vs. 52.2%, P=0.003), but not distant metastasis-free survival (DMFS: 69.6% vs. 63.6%, P=0.669). However, CRT did not significantly improve 5-year OS (43.6% vs. 27.3%, P=0.893) or CSS (43.6% vs. 34.1%, P=0.971) in elderly NPC patients with ACE-27 score≥2. CRT is feasible and effective in

    Redbay ambrosia beetle, Xyleborus glabratus Eichhoff, is an exotic wood-borer that vectors the fungal agent (Raffaelea lauricola) responsible for laurel wilt. Laurel wilt has had severe impact on forest ecosystems in the southeastern United States, killing a large proportion of native Persea trees, particularly redbay (P. borbonia) and swampbay (P. palustris), and currently poses an economic threat to avocado (P. americana) in Florida. To control the spread of this lethal disease, effective attractants are needed for early detection of the vector. Two 12-wk field tests were conducted in Florida to evaluate efficacy and longevity of manuka and phoebe oil lures, and to relate captures of X. glabratus to release rates of putative sesquiterpene attractants. Two trap types were also evaluated, Lindgren funnel traps and sticky panel traps. To document lure emissions over time, a separate set of lures was aged outdoors for 12 wk and sampled periodically to quantify volatile sesquiterpenes using super-Q adsorbant and gas chromatography-mass spectroscopy analysis. Phoebe lures captured significantly more X. glabratus than manuka lures, and sticky traps captured more beetles than funnel traps. Phoebe lures captured X. glabratus for 10-12 wk, but field life of manuka lures was 2-3 wk. Emissions of alpha-copaene, alpha-humulene, and cadinene were consistently higher from phoebe lures, particularly during the 2-3 wk window when manuka lures lost efficacy, suggesting that these sesquiterpenes are primary kairomones used by host-seeking females. Results indicate that the current monitoring system is suboptimal for early detection of X. glabratus because of rapid depletion of sesquiterpenes from manuka lures. PMID:22606839

    Full Text Available We evaluated the efficacy and toxicity of cisplatin/docetaxel (CDDP/TXT chemotherapy and identified prognostic factors in Japanese patients with cancer of unknown primary site (CUP. Twenty-eight consecutive patients seen at a single institute were reviewed retrospectively. Sixteen patients were treated with TXT 80mg/m2, followed by CDDP 75mg/m2. The overall response rate to CDDP/TXT treatment was 62.5%, with a median survival time (MST of 22.7 months. Common adverse reactions were myelosuppression and hyponatremia. The MST of all 28 patients with CUP was 8.3 months, and the 1-year overall survival rate was 45.6%. Univariate analysis identified 5 prognostic factors:performance status, liver involvement, bone involvement, pleural involvement, and lymph node involvement. In conclusion, CDDP/TXT chemotherapy is effective with tolerable toxicity in patients with CUP. Japanese patients with CUP might be chemosensitive and may survive longer.

    To compare percutaneous nephrolithotomy (PCNL) and laparoscopic pyelolithotomy (LP) for surgical management for large (>2 cm) renal stones. We searched MEDLINE, Cochrane, and EMBASE databases until March 11, 2015, using the following search terms: renalpelvic stone, percutaneous nephrolithotomy, laparoscopic pyelolithotomy. Randomized controlled and prospective and retrospective two-armed studies were included. Sensitivity analysis and assessment of the quality of the included studies and publication bias were performed. Nine studies were included in the study with a patient population of 622. The studies were homogeneous with respect to the primary end point of stone-free rate, but were heterogeneous with respect to operation time, length of hospital stay, and blood loss. A higher percentage of patients who received LP remained stone-free following surgery compared with patients who were treated with PCNL (p=0.001). However, the mean operation time was longer for patients with LP than for those treated with PCNL (p=0.002). There was no difference between procedures with regard to length of hospital stay or blood loss (p≥0.071). Sensitivity and quality analysis indicated that the data are reliable and the included studies are of good quality. No publication bias was observed. The study suggests that both procedures are effective and safe for removing large renal stones. However, LP may be more efficacious than PCNL in treating large kidney stones. PMID:27222519

It remains unclear whether tenofovir disoproxil fumarate- (TDF- based combination therapy produces better outcomes than TDF monotherapy in chronic hepatitis B (CHB patients. The aim of this study was to compare the efficacy of the two regimens by performing a meta-analysis. Methods. A comprehensive literature search was performed on the comparison of TDF-based combination therapy and monotherapy for CHB patients in the PubMed, Embase, Web of Science, and the Cochrane Libraries. Both dichotomous and continuous variables were extracted and pooled outcomes were expressed as risk ratio (RR or standard mean difference (SMD. Results. Nine eligible studies (1089 subjects in total were included in our analysis. The proportion of patients with undetectable HBV DNA at 24, 48, and 96 weeks were similar between the two comparable groups (62.5% versus 70.9%, P=0.086; 78.1% versus 83.7%, P=0.118; 86.4% versus 87.9%, P=0.626, resp.. HBV DNA reduction, rates of ALT normalization, hepatitis B e antigen (HBeAg loss, and HBeAg seroconversion were also similar between the two groups. Conclusions. On the current data, TDF-based combination therapy seemed to be no better than those achieved by monotherapy. Further studies are needed to verify this comparison.

    To compare the efficacy and safety of combined radiofrequency ablation (RFA) and transcatheter arterial chemoembolization (TACE) with RFA alone for hepatocellular carcinomas (HCC). Randomized controlled trial (RCT) studies that compared the clinical or oncologic outcomes of combination therapy of TACE and RFA versus RFA for the treatment of HCC were identified through literature searches of electronic databases (Pubmed, Embase, Cochrane Library, China Biology Medicine disc, China National Knowledge Infrastructure, and Google Scholar). Hazard ratios (HRs) or odds ratios (ORs) with their corresponding 95% confidence interval (CI) were combined as the effective value to assess the summary effects. The strength of evidence was rated by the Grading of Recommendations Assessment, Development, and Evaluation system. Six RCTs with 534 patients were eligible for inclusion in this meta-analysis. The meta-analysis showed that the combination of TACE and RFA is associated with a significantly longer overall survival (HR = 0.62, 95% CI: 0.49-0.78, p < 0.001) and recurrence-free survival (HR = 0.55, 95% CI: 0.40-0.76, p < 0.001) in contrast with RFA monotherapy. The seemingly higher incidence of major complications in the combination group compared with RFA group did not reach statistical significance (OR = 1.17, 95% CI: 0.39-3.55, p = 0.78). In patients with HCC, the combination of TACE and RFA is associated with significantly higher overall survival and recurrence-free survival, as compared with RFA monotherapy, without significant difference in major complications.

    Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease with rising prevalence. Increasing evidence has demonstrated that resveratrol, a dietary phytochemical, is capable of attenuating NAFLD development and progression; however, results from clinical studies are inconsistent and inconclusive. Here, we conducted a meta-analysis to evaluate the efficacy of resveratrol on NAFLD, using several parameters to provide new insights for clinical application. We systematically searched EMBASE, PubMed, Science Citation Index, Elsevier, and Cochrane Library databases for studies published up to date (July 2016), in English, to identify and screen eligible, relevant studies. Either a fixed-effect model or random model was used to estimate mean difference (MD) and 95% confidence intervals (CIs) for the effect of resveratrol on NAFLD. Four randomized, double-blinded, placebo-controlled trials involving 156 patients were included in the meta-analysis. Levels of low-density lipoprotein (MD = 0.47, 95% CI: 0.21, 0.74, P resveratrol treatment groups than in placebo control groups, whereas other parameters were not altered. Overall, this study indicates that resveratrol treatment has negligible effects on attenuating NAFLD, given the small improvement in NAFLD features. More high-quality clinical trials of resveratrol for NAFLD are required to confirm these results. PMID:27560482

    Liraglutide, a glucagon-like peptide (GLP-1) receptor agonist, has showed favorable effects in the glycaemic control and weight reduction in patients with type 2 diabetes mellitus (T2DM). The meta-analysis was to compare the efficacy and safety of liraglutide added to metformin with other treatments in patients with T2DM. A systematic literature search on PubMed, Embase, Web of Science and the Cochrane library databases were performed. Eligible studies were randomized controlled trials (RCTs) of patients with T2DM who received the combination treatment of liraglutide and metformin. Pooled estimates were performed using a fixed-effects model or random-effects model. A total of nine RCTs met the inclusion criteria. Compared with control (placebo, sitagliptin, glimepiride, dulaglutide, insulin glargine, and NPH), liraglutide in combination with metformin resulted in significant reductions in HbA1c, bodyweight, FPG, and PPG, and similar reductions in SBP, and DBP. Moreover, liraglutide combined with metformin did not increase the risk of hypoglycemia, but induced a higher incidence of gastrointestinal disorders. In conclusion, this meta-analysis confirmed the use of liraglutide as add-on to metformin appeared to be effective and safe for patients with T2DM. However, considering the potential limitations in this study, more large-scale, well-conducted RCTs are needed to identify our findings.

    Traditionally many structural alloys are protected by primer coatings loaded with corrosion inhibiting additives. Strontium Chromate (or other chromates) have been shown to be extremely effectively inhibitors, and find extensive use in protective primer formulations. Unfortunately, hexavalent chromium which imbues these coatings with their corrosion inhibiting properties is also highly toxic, and their use is being increasingly restricted by legislation. In this work we explore a novel tridimensional Quantitative-Structure Property Relationship (3D-QSPR) approach, comparative molecular surface analysis (CoMSA), which was developed to recognize "high-performing" corrosion inhibitor candidates from the distributions of electronegativity, polarizability and van der Waals volume on the molecular surfaces of 28 small organic molecules. Multivariate statistical analysis identified five prototypes molecules, which are capable of explaining 71% of the variance within the inhibitor data set; whilst a further five molecules were also identified as archetypes, describing 75% of data variance. All active corrosion inhibitors, at a 80% threshold, were successfully recognized by the CoMSA model with adequate specificity and precision higher than 70% and 60%, respectively. The model was also capable of identifying structural patterns, that revealed reasonable starting points for where structural changes may augment corrosion inhibition efficacy. The presented methodology can be applied to other functional molecules and extended to cover structure-activity studies in a diverse range of areas such as drug design and novel material discovery.

    The purpose of this meta-analysis was to assess the efficacy of prophylactic administration of 5-HT3 receptor antagonists for postoperative nausea and vomiting in neurosurgical patients at 24 and 48+ hours. After a systematic search, 7 published randomized placebo controlled trials involving 448 craniotomy patients (222 treatment, 226 control) were included in the meta-analysis. Study drugs included ondansetron, granisetron, and tropisetron. The cumulative incidence of emesis was significantly reduced in the treatment group at 24 hours [relative risk (RR)=0.50, 95% confidence interval (CI): 0.38-0.66] and 48+ hours (RR=0.52, 95% CI: 0.36-0.75). There were no differences between the treatment and control groups in the cumulative incidence of nausea at 24 hours (RR=0.76, 95% CI: 0.54-1.06) and 48+ hours (RR=0.81, 95% CI: 0.62-1.06). The cumulative incidence of both nausea and vomiting continued to increase after 24 hours in both groups. Despite the ability of 5-HT3 receptor antagonists to reduce emetic episodes, future investigations should seek to address the control of postoperative nausea and to reduce further postoperative emesis in this population.

    The study was designed to test the relationship of principals' transformational, transactional, and laissez-faire leadership with teachers' collective efficacy. Bandura's theory of efficacy applied to the group and Bass's transformational leadership theory were used as the theoretical framework. Participants included 487 French Canadian teachers from 40 public high schools. As expected, there were positive and significant correlations between principals' transformational and transactional leadership and teachers' collective efficacy. Also, there was a negative and significant correlation between laissez-faire leadership and teachers' collective efficacy. Moreover, regression analysis showed transformational leadership significantly enhanced the predictive capabilities of transactional leadership on teachers' collective efficacy. These results confirm the importance of leadership to predict collective efficacy and, by doing so, strengthen Bass's theory of leadership. PMID:18567210

A growing body of evidence demonstrates that interleukin-17 (IL-17 is also synthesized in inflammatory arthritis tissues and exerts potent proinflammatory and joint-destructive activities. Clinical studies have been performed to evaluate the therapeutic efficacy of antibodies blocking the IL-17 signaling pathway in patients with rheumatoid arthritis (RA. In this study, we performed a meta-analysis to systematically evaluate the clinical effects of IL-17 antibodies in RA patients. By searching PubMed, five randomized, placebo-controlled randomized controlled clinical trials that tested three antibodies against IL-17A (LY2439821 and secukinumab/AIN457 and the IL-17A receptor (brodalumab were identified. The primary outcomes that were analyzed include American College of Rheumatology (ACR Improvement Criteria and Disease Activity Score in 28 joints (DAS28. Meanwhile, the safety and adverse effects were also systematically analyzed. The results of the meta-analysis demonstrated that IL-17 antibody is effective in ameliorating the RA symptoms. Specifically, IL-17-blocking antibody significantly reduced ACR20 and ACR50. It also dramatically reduced DAS28, an index that measures tenderness and swelling severity of joints. The side effects of and intolerance to the antibody treatment were higher than those in the placebo control. The analysis result provides evidence-based information for clinical use of these agents in the treatment of inflammatory arthritis.

    Full Text Available Abstract Background Pulmonary Rehabilitation for moderate Chronic Obstructive Pulmonary Disease in primary care could improve patients’ quality of life. Methods This study aimed to assess the efficacy of a 3-month Pulmonary Rehabilitation (PR program with a further 9 months of maintenance (RHBM group compared with both PR for 3 months without further maintenance (RHB group and usual care in improving the quality of life of patients with moderate COPD. We conducted a parallel-group, randomized clinical trial in Majorca primary health care in which 97 patients with moderate COPD were assigned to the 3 groups. Health outcomes were quality of life, exercise capacity, pulmonary function and exacerbations. Results We found statistically and clinically significant differences in the three groups at 3 months in the emotion dimension (0.53; 95%CI0.06-1.01 in the usual care group, (0.72; 95%CI0.26-1.18 the RHB group (0.87; 95%CI 0.44-1.30 and the RHBM group as well as in fatigue (0.47; 95%CI 0.17-0.78 in the RHBM group. After 1 year, these differences favored the long-term rehabilitation group in the domains of fatigue (0.56; 95%CI 0.22-0.91, mastery (0.79; 95%CI 0.03-1.55 and emotion (0.75; 95%CI 0.17-1.33. Between-group analysis only showed statistically and clinically significant differences between the RHB group and control group in the dyspnea dimension (0.79 95%CI 0.05-1.52. No differences were found for exacerbations, pulmonary function or exercise capacity. Conclusions We found that patients with moderate COPD and low level of impairment did not show meaningful changes in QoL, exercise tolerance, pulmonary function or exacerbation after a one-year, community based rehabilitation program. However, long-term improvements in the emotional, fatigue and mastery dimensions (within intervention groups were identified. Trial registration ISRCTN94514482

    Full Text Available Objective: To estimate and compare the cost-effectiveness and safety of nebivolol with sustained-release metoprolol in reducing blood pressure by 1 mm of Hg per day in hypertensive patients. Materials and Methods: This was a prospective, randomized, open label, observational analysis of cost-effectiveness, in a questionnaire-based fashion to compare the cost of nebivolol (2.5 mg, 5 mg, 10 mg and sustained released metoprolol succinate (25 mg, 50 mg, 100 mg in hypertensive patients using either of the two drugs. A total of 60 newly detected drug naïve hypertensive patients were considered for the comparison, of which 30 patients were prescribed nebivolol and the other 30 were prescribed metoprolol succinate as per the recommended dosage. Based on the data, statistical analysis was carried out using GraphPad Prism 5 and MS Excel Spreadsheet 2007. Result: The cost of reducing 1 mm of Hg blood pressure per day with nebivolol was 0.60, 0.70, and 1.06 INR, whereas that of metoprolol succinate was 0.93, 1.18, and 1.25 INR at their respective equivalent doses, hence significantly lower with the nebivolol group as compared to the metoprolol group (P < 0.05. Conclusion: This pharmacoeconomic analysis shows that nebivolol is more cost-effective as compared to metoprolol when the cost per reduction in blood pressure per day is considered. This may affect the patients economically during their long-term use of these molecules for the treatment of hypertension.

    Tumor thermotherapy is a method of cancer treatment wherein cancer cells are killed by exposing the body tissues to high temperatures. Successful clinical implementation of this method requires a clear understanding and assessment of the changes of the tumor area after the therapy. In this study, we evaluated the effect of near-infrared laser tumor thermotherapy at the molecular, cellular, and physical levels. We used single-walled carbon nanotubes (SWNTs) in combination with this thermotherapy. We established a mouse model for breast cancer and randomly divided the mice into four groups: mice with SWNT-assisted thermotherapy; mice heat treated without SWNT; mice injected with SWNTs without thermotherapy; and a control group. Tumors were irradiated using a near-infrared laser with their surface temperature remaining at approximately 45 °C. We monitored the tumor body growth trend closely by daily physical measurements, immunohistochemical staining, and H&E (hematoxylin-eosin) staining by stage. Our results showed that infrared laser hyperthermia had a significant inhibitory effect on the transplanted breast tumor, with an inhibition rate of 53.09%, and also significantly reduced the expression of the heat shock protein Hsp70. Furthermore, we have found that protein analysis and histological analysis can be used to assess therapeutic effects effectively, presenting broad application prospects for determining the effect of different treatments on tumors. Finally, we discuss the effects of SWNT-assisted near-infrared laser tumor thermotherapy on tumor growth at the molecular, cellular, and physical levels.

    Foot and mouth disease (FMD) outbreaks have been reported in China for many years. Recently, due to the rapid economic development, the price of meat and its demand have grown quickly. This trend has resulted in an increase in the number of livestock moving from south-east Asian countries into China. Foot and mouth disease is becoming one of the most important trans-boundary animal diseases affecting the livelihood of livestock owners in China. To contribute to the long term goal to control and eradicate FMD from China, the Chinese government has adopted a series of control measures which includes compulsory routine vaccination against the disease. In this paper, the surveillance results of the routine vaccination programme were systemically reviewed. The results from 28 published papers were combined and analysed through a meta-analysis approach. The results of the meta-analysis indicated that the vaccination programme has been very successful in China with more than 70% of animals protected against serotypes Asia-1 and O.

    Tumor thermotherapy is a method of cancer treatment wherein cancer cells are killed by exposing the body tissues to high temperatures. Successful clinical implementation of this method requires a clear understanding and assessment of the changes of the tumor area after the therapy. In this study, we evaluated the effect of near-infrared laser tumor thermotherapy at the molecular, cellular, and physical levels. We used single-walled carbon nanotubes (SWNTs) in combination with this thermotherapy. We established a mouse model for breast cancer and randomly divided the mice into four groups: mice with SWNT-assisted thermotherapy; mice heat treated without SWNT; mice injected with SWNTs without thermotherapy; and a control group. Tumors were irradiated using a near-infrared laser with their surface temperature remaining at approximately 45 °C. We monitored the tumor body growth trend closely by daily physical measurements, immunohistochemical staining, and H and E (hematoxylin-eosin) staining by stage. Our results showed that infrared laser hyperthermia had a significant inhibitory effect on the transplanted breast tumor, with an inhibition rate of 53.09%, and also significantly reduced the expression of the heat shock protein Hsp70. Furthermore, we have found that protein analysis and histological analysis can be used to assess therapeutic effects effectively, presenting broad application prospects for determining the effect of different treatments on tumors. Finally, we discuss the effects of SWNT-assisted near-infrared laser tumor thermotherapy on tumor growth at the molecular, cellular, and physical levels.

    Anterior knee pain is a chronic condition that presents frequently to sports medicine clinics, and can have a long-term impact on participation in physical activity. Conceivably, effective early management may prevent chronicity and facilitate physical activity. Although a variety of nonsurgical interventions have been advocated, previous systematic reviews have consistently been unable to reach conclusions to support their use. Considering a decade has lapsed since publication of the most recent data in these reviews, it is timely to provide an updated synthesis of the literature to assist sports medicine practitioners in making informed, evidence-based decisions. A systematic review and meta-analysis was conducted to evaluate the evidence for nonsurgical interventions for anterior knee pain. A comprehensive search strategy was used to search MEDLINE, EMBASE, CINAHL and Pre-CINAHL, PEDro, PubMed, SportDiscus, Web of Science, BIOSIS Previews, and the full Cochrane Library, while reference lists of included papers and previous systematic reviews were hand searched. Studies were eligible for inclusion if they were randomized clinical trials that used a measure of pain to evaluate at least one nonsurgical intervention over at least 2 weeks in participants with anterior knee pain. A modified version of the PEDro scale was used to rate methodological quality and risk of bias. Effect size calculation and meta-analyses were based on random effects models. Of 48 suitable studies, 27 studies with low-to-moderate risk of bias were included. There was minimal opportunity for meta-analysis because of heterogeneity of interventions, comparators and follow-up times. Meta-analysis of high-quality clinical trials supports the use of a 6-week multimodal physiotherapy programme (standardized mean difference [SMD] 1.08, 95% CI 0.73, 1.43), but does not support the addition of electromyography biofeedback to an exercise programme in the short-term (4 weeks: SMD -0.21, 95% CI -0.64, 0

    Full Text Available The objective of this study was to evaluate the effectiveness and safety of entecavir (ETV and interferon (IFN combination therapy in the treatment of chronic hepatitis B (CHB mono-infection via a meta-analysis of randomized controlled trials (RCTs. All eligible RCTs evaluating combination therapy for treating CHB were identified from nine electronic databases. A meta-analysis was performed in accordance with the Cochrane Systemic Review handbook. Eleven trials encompassing 1010 participants were included in this meta-analysis. It showed that at 12 and ≥ 96 weeks of therapy, the combination of ETV and IFN was not better than ETV in improving the undetectable HBV DNA (12 weeks: RR=1.12, 95% CI=0.88-1.42; ≥ 96 weeks: RR = 0.64, 95% CI=0.21-1.98, respectively and HBeAg seroconversion rates (12 weeks: RR=1.35, 95% CI=0.60-3.04; ≥ 96 weeks: RR=1.36, 95% CI=0.75-2.64, respectively. But at 48 weeks of therapy and approximately 2 years of follow up, combination therapy was superior to ETV in improving the undetectable HBV DNA (48 weeks: RR=1.46, 95% CI=1.13-1.90; follow up: RR=2.20, 95% CI=1.26-3.81, respectively and HBeAg seroconversion rates (48 weeks: RR=1.82, 95% CI=1.44-2.30; follow up: RR=1.92, 95% CI=1.19-3.11, respectively. When compared to IFN group, at 24 and 48 weeks of therapy, combination group showed a greater undetectable HBV DNA (24 weeks: RR=2.14, 95% CI=1.59-2.89; 48 weeks: RR=2.28, 95% CI=1.54-3.37, respectively and ALT normalization rate (24 weeks: RR=1.56, 95% CI= 1.24-1.96; 48 weeks: RR=1.55, 95% CI = 1.16-2.07, respectively. At 48 weeks of therapy, combination group achieved a greater HBeAg seroconversion rate than IFN (48 weeks: RR=1.58, 95% CI=1.24-2.00. No significant differences were observed in the side effects of the three therapies. So we can conclude that ETV and IFN combination therapy is more effective than ETV or IFN mono-therapy in CHB treatment. ETV, IFN, and the combination of the two are safe in CHB treatment.

    Aims: We present an analysis of the effects of integrating galaxy morphological information in photometric redshift (photo-z) estimation with a custom support vector machine (SVM) classification package. We also present a comparison with other methods. Statistical correlations between galaxy shape information and redshift that are not degenerate with photometric band magnitudes would be evident through an improvement in the accuracy of photo-z estimations, or possibly even in a lack of significant loss of accuracy in light of the noise introduced by including additional parameters. Methods: SVM algorithms, a type of machine learning, utilize statistical learning theory and optimization theory to construct predictive models based on the information content of data in a way that can treat different input types symmetrically, which can be a useful estimator of the additional information contained in parameters, such as those describing the morphology of the galaxies. The custom SVM classification code we have de...

    Purpose: To elucidate the performance of transcatheter aortic valve implantation (TAVI) in bicuspid aortic valve (BAV) patients through a systematic review and meta-analysis. Methods: A systematic literature review was performed by searching eligible articles in PubMed, Medline, EMBASE, Google Scholar and CNKI. Meta-analysis of included case-control/cohort studies was further conducted. Relative risks (RRs) and the corresponding 95% confidence intervals (CIs) were used to compare clinical outcomes of BAV patients and non-BAV patients. Results: A total of 17 articles including eight case reports, four case series and five case-control/cohort studies with 166 BAV patients were analyzed. Device success rate achieved for TAVI in this cohort of BAV patients was 95.2%. The 30-day mortality rate was 8.4%, and the medium-term (range from 6 months to 2 years) mortality rate reported was 17.9%. Overall, the performance of TAVI in BAV patients was comparable to that in non-BAV patients, as reported by the included case-control/cohort studies (30-day mortality rate: RR = 1.05, 95%CI 0.57–1.95, p = 0.87; Device success rate: RR = 1.00, 95%CI 0.95–1.05, p = 0.94; Incidence of moderate to severe paravalvular regurgitation: RR = 1.25, 95%CI 0.85–1.84, p = 0.25). Conclusion: The present study suggested that TAVI may be a feasible and safe treatment modality for BAV patients. PMID:27098769

    Full Text Available Background. Controversies on the utility of laparoscopic mini gastric bypass (LMGB in weight loss and type 2 diabetes mellitus (T2DM control still exist. Methods. We conducted a comprehensive literature search of PubMed, EMBASE, and Cochrane Library. Review Manager was used to perform the meta-analysis and the weighted mean difference (WMD and/or odds ratio with 95% confidence interval (95% CI were used to evaluate the overall size effect. Results. The literature search identified 16 studies for systematic review and 15 articles for meta-analysis. Compared with LAGB, LSG, and LRYGB, LMGB showed significant weight loss [WMD, −6.58 (95% CI, −9.37, −3.79, P<0.01 (LAGB; 2.86 (95% CI, 1.40, 5.83, P=0.004 (LSG; 10.33 (95% CI, 4.30, 16.36, P<0.01 (LRYGB] and comparable/higher T2DM remission results [86.2% versus 55.6%, P=0.06 (LAGB; 89.1% versus 76.3%, P=0.004 (LAGB; 93.4% versus 77.6%, P=0.006 (LAGB]; LMGB also had shorter learning curve and less operation time than LRYGB [WMD, −35.2 (95% CI, −46.94, −23.46]. Conclusions. LMGB appeared to be effective in weight loss and T2DM remission and noninferior to other bariatric surgeries. However, clinical utility of LMGB needs to be further validated by future prospective randomized controlled trials.

    Background: The aim of the present study was to compare the efficacy of interferon (IFN) with or without different nucleos(t)ide analogues (NAs). Methods: The PubMed, Wan Fang and CNKI databases were searched to identify relevant trials up to May 2015. Meta-analysis was performed with Review Manager 5.0. The stability and reliability were evaluated by publication bias tests. Results: Fifty-six studies fulfilled the criteria for the meta-analysis. Compared with IFN monotherapy, combination therapy were superior in HBV DNA undetectable rate (Risk Ratio (RR) = 1.55, 95% confidence interval (CI): 1.44–1.66, p < 0.00001), HBeAg and HBsAg loss rate (RR = 1.38, 95% CI: 1.22–1.56, p < 0.00001; RR = 1.69, 95% CI: 1.03–2.78, p = 0.04, respectively) at the end of week 48 treatment. Sub-analysis showed the RRs of virological response for entecavir (ETV), adefovir (ADV), and lamivudine (LAM) were 1.64, 1.61 and 1.52, respectively; RRs of HBeAg loss rate were 1.34, 1.71 and 1.34, respectively. However, at the end of follow-up, IFN plus NAs therapy was better than IFN monotherapy only in terms of HBV DNA undetectable rate (p = 0.0007). Conclusions: Combination therapy was better than IFN monotherapy in virological and serological responses at the end of treatment. After follow-up, only HBV DNA undetectable rate was superior for combination therapy. PMID:27455288

    Introduction Many antidepressants are indicated for the treatment of major depression. Two network meta-analyses have provided the most comprehensive assessments to date, accounting for both direct and indirect comparisons; however, these reported conflicting interpretation of results. Here, we present a protocol for a systematic review and network meta-analysis aimed at updating the evidence base and comparing all second-generation as well as selected first-generation antidepressants in terms of efficacy and acceptability in the acute treatment of major depression. Methods and analysis We will include all randomised controlled trials reported as double-blind and comparing one active drug with another or with placebo in the acute phase treatment of major depression in adults. We are interested in comparing the following active agents: agomelatine, amitriptyline, bupropion, citalopram, clomipramine, desvenlafaxine, duloxetine, escitalopram, fluoxetine, fluvoxamine, levomilnacipran, milnacipran, mirtazapine, nefazodone, paroxetine, reboxetine, sertraline, trazodone, venlafaxine, vilazodone and vortioxetine. The main outcomes will be the proportion of patients who responded to or dropped out of the allocated treatment. Published and unpublished studies will be sought through relevant database searches, trial registries and websites; all reference selection and data extraction will be conducted by at least two independent reviewers. We will conduct a random effects network meta-analysis to synthesise all evidence for each outcome and obtain a comprehensive ranking of all treatments. To rank the various treatments for each outcome, we will use the surface under the cumulative ranking curve and the mean ranks. We will employ local as well as global methods to evaluate consistency. We will fit our model in a Bayesian framework using OpenBUGS, and produce results and various checks in Stata and R. We will also assess the quality of evidence contributing to network

    We present a comparative evaluation of five different neuroprotective drugs in the early phase following focal traumatic brain injury (TBI) in mouse intact head. The effectiveness of these drugs in terms of changes in brain tissue morphology and hemodynamic properties was experimentally evaluated through analysis of the optical absorption coefficient and spectral reduced scattering parameters in the range of 650-1000 nm. Anesthetized male mice (n=50 and n=10 control) were subjected to weight drop model mimics real life focal head trauma. Monitoring the effect of injury and neuroprotective drugs was obtained by using a diffuse reflectance spectroscopy system utilizing independent source-detector separation and location. Result indicates that administration of minocycline improve hemodynamic and reduced the level of tissue injury at an early phase post-injury while hypertonic saline treatment decrease brain water content. These findings highlight the heterogeneity between neuroprotective drugs and the ongoing controversy among researchers regarding which drug therapy is preferred for treatment of TBI. On the other hand, our results show the capability of optical spectroscopy technique to noninvasively study brain function following injury and drug therapy.

    Full Text Available This study aimed to evaluate the clinical efficacy and safety of using the traditional Chinese herbal medicine Scutellaria baicalensis for the treatment of severe HFMD in 725 patients aged >1 year in a multicenter, retrospective analysis. The patients were divided into the S. baicalensis and ribavirin groups, and the temperatures, presence or absence of skin rashes and oral lesions, nervous system (NS involvement, and viral loads of the patients, as well as the safety of the treatments, were evaluated. The median duration of fever, median time to NS involvement, and the number of patients with oral ulcers and/or vesicles, as well as skin rashes, were decreased in the S. baicalensis group compared with the ribavirin group. In addition, the EV71 viral loads were decreased in the S. baicalensis group, suggesting that S. baicalensis exerted more potent antiviral effects compared with ribavirin. The present study demonstrated that S. baicalensis was suitable for the treatment of severe HFMD in patients aged >1 year, since it was shown to rapidly relieve fever, attenuate oral lesions and rashes, and improve NS involvement. Furthermore, it was demonstrated to be relatively safe for topical application.

    The aim of this study was to evaluate evidence for the efficacy of aloe vera on managing prediabetes and early non-treated diabetes mellitus. We performed a systematic search of PubMed, Embase, and Cochrane Central Register of Controlled Trials until 28 January 2016. A total of five randomized controlled trials (RCTs) involving 415 participants were included. Compared with the controls, aloe vera supplementation significantly reduced the concentrations of fasting blood glucose (FBG) (p = 0.02; weighed mean difference [WMD]: −30.05 mg/dL; 95% confidence interval [CI]: −54.87 to −5.23 mg/dL), glycosylated hemoglobin A1c (HbA1c) (p Aloe vera was superior to placebo in increasing serum high density lipoprotein-cholesterol (HDL-C) levels (p = 0.04). Only one adverse event was reported. The evidence from RCTs showed that aloe vera might effectively reduce the levels of FBG, HbA1c, triglyceride, TC and LDL-C, and increase the levels of HDL-C on prediabetes and early non-treated diabetic patients. Limited evidence exists about the safety of aloe vera. Given the small number and poor quality of RCTs included in the meta-analysis, these results are inconclusive. A large-scale, well-designed RCT is needed to further address this issue. PMID:27347994

    Forceps biopsy (FB) is the most commonly used diagnostic tool for lung pathologies. FB is associated with a high diagnostic failure rate. Cryobiopsy (CB) is a novel technique providing a larger specimen size, few artefacts, more alveolar parts and superior diagnostic yield. CB, however, has drawbacks such as higher bleeding and pneumothorax rate. We conducted a meta-analysis to investigate the specimen area, diagnostic rate and bleeding severity in CB versus FB in interstitial lung diseases (ILDs) and lung tumours. A systematic literature search of PUBMED, BIOSIS PREVIEW and OVID databases was conducted using specific search terms. Eligible studies including RCTs and non-RCTs comparing cryobiopsy/cryotransbronchial biopsy (CB/CTBB) and forceps biopsy/forceps transbronchial biopsy (FB/FTBB) for specimen area, diagnostic rate and bleeding rate in ILDs and lung tumours were analysed. Two reviewers independently extracted data and evaluated the quality of the studies. Eight studies involving 916 patients were analysed. Specimen area (mm(2) ) was significantly larger in CB/CTBB than FB/FTBB (standard mean difference = 1.21, 95% confidence interval (0.94, 1.48), P FB/FTBB (Risk ratio 1.36, 95% confidence interval (1.16, 1.59), P = 0.0002). Three studies compared the bleeding severity with only one showing significantly more bleeding in CB. Cryobiopsy/cryotransbronchial shows superiority to FB/FTBB for specimen area and diagnostic rate. CB/CTBB has better efficacy over FB/FTBB.

    To evaluate the efficacy and complications of ultrasound-guided percutaneous renal biopsy using 18G automatic biopsy gun in patients with diffuse renal disease. 203 ultrasound-guided renal biopsies using 18G automatic biopsy gun were performed in 197 patients for the diagnosis of diffuse renal disease. The success and complication rates were retrospectively evaluated by analysis of pathologic and clinical records and post-procedure ultrasonograms of the patients. Out of 203 renal biopsies, adequate tissues for pathologic diagnosis were obtained in 184 (90.6%) biopsies. The mean number of needle passes was 2.08, and the mean number of retrieved glomeruli was 7.71 {+-} 4.23. Minor complications occurred in seven biopsies (3.45%) including asymptomatic macroscopic hematuria in five (2.45%) and small subcapsular hematomas in two (1%). No patients required transfusion or surgery because of biopsy-related complication. Ultrasound-guided percutaneous renal biopsy using 18G automatic biopsy gun was an effective method for the pathologic diagnosis of diffuse renal disease and safe with low complication rate related to the procedure.
