Objective: To assess the effectiveness and tolerability of the 23 mg tablet donepezil in patients with Alzheimer’s disease (AD) using meta-analysis of randomized controlled trials. Methods: Major healthcare databases were searched from May to September 2016. Evaluation of relevant trials, assessment of risk of bias, collection and analyses of data were performed. Results: A total of 1,774 adult participants with AD were pooled from the two trials included. Pooled data showed that after 24 weeks of treatment, no significant difference was noted between Donepezil 23 mg/day and Donepezil 10 mg/day in terms of cognitive function (1.06 SIB points [-0.13, 2.26]; 1704 participants) and in terms of global clinical assessment (-0.02 CIBIC+ points [-0.13, 0.09]; 1705 participants). The participants who took the higher dose were at higher risk to experience “any adverse event” than those who received the lower dose (1.17 RR [1.09, 1.26]; 1785 participants). Conclusion Current evidences do not support the routine use of Donepezil 23 mg tablet for the improvement of cognitive function and global clinical status of patients with AD. The higher dose is also marked with an increased incidence of adverse events compared to the lower dose.

Background: Schizophrenia is a pervasive, chronic mental disorder that negatively impacts the biological, socioeconomic and family well being of the patient. Active involvement of family members and other significant individuals appears to benefit overall management. Objective: To determine the effectiveness of family-focused intervention in improving symptoms of schizophrenia. Methods: The authors searched for eligible clinical trials in the PubMed, Cochrane Central Register of Controlled Trials, Research Gate, Google Scholar and grey literature databases. Participants should be patients diagnosed to have schizophrenia and interventions should involve the family or be labeled as ‘family therapy.’ The primary outcome considered was symptom improvement based on the Positive and Negative Symptom Scale (PANSS). Secondary outcomes included quality of life, family functioning and subjective experience of the treatment process. The authors used the RevMan 5.4 software for data analysis. Bias, subgroup and sensitivity analyses were performed. Strength of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) framework. Results: A total of 1,794 trials were initially identified, of which three publications were included in the review. Two studies used psychosocial approaches whereas one used cognitive behavioral therapy in conjunction with family intervention. Meta-analysis revealed the studies to be heterogeneous based on p values <0.10 and I2 >50%. Subgroup analysis by type of intervention showed no difference between the intervention and control groups, although there was a positive trend in favor of psychosocial intervention for improvement in PANSS score. Family-based intervention had a significant positive effect on quality of life. Conclusion Family-based interventions are effective in the management of schizophrenia, helping to improve quality of life, potentially reducing symptom burden and serving as an adjunct to health institution-based management.

Aims: This meta-analysis aims to synthesize available evidence from published studies on the effectiveness of parental non-pharmacologic smoking cessation programs which aim to reduce children's exposure to secondhand smoke.

Methodology: A database search using The Cochrane Library, PubMed®, Medline, Embase, and Google Scholar, was done by the investigators. This study included 20 randomized controlled trials published up to 2020. Pooled estimates of risk ratio (RR) for quit rates were computed using the random effects model.

Results: Overall, the quit rate among those who underwent parental smoking cessation was 13.4% while the quit rate for controls was 11.9%. The pooled RR demonstrated that the parental smoking cessation program was significantly associated with higher quit rates (RR = 1.22, 95%CI = 1.01 to 1.46, p-value = 0.04). The studies demonstrated moderate heterogeneity only (I2 = 54%). Among studies published prior to year 2000, no significant difference was observed between parental smoking cessation program and control (RR = 1.02, 95% CI = 0.62 to 1.70, p-value = 0.93). On the other hand, the pooled RR demonstrated that among studies published after 2020, parental smoking cessation program was significantly associated with higher quit rates (RR = 1.27, 95%CI = 1.03 to 1.56, p-value <0.0001). Among studies with self-help interventions, parental smoking cessation program has no additional benefit on quit rates (RR = 1.20, 95%CI = 0.94 to 1.58, p-value = 0.14). Among studies with biofeedback intervention also, no significant difference was observed (RR = 1.27, 95% CI = 0.86 to 1.89, p-value = 0.23).

Conclusions: This meta-analysis demonstrated sufficient evidence that non-pharmacologic interventions for parental smoking cessation are effective.

Background: Fibromyalgia is a difficult-to-treat chronic musculoskeletal pain and tenderness syndrome. It is considered due to augmented pain processing in central nervous system. Interest in antiepileptic drugs, included pregabalin, for treatment of fibromyalgia is currently growing. This study aimed to investigate the effectiveness of pregabalin for fibromyalgia. Methods: We conducted the study according to the meta-analysis PRISMA guideline. Relevant randomized controlled trials (RCTs) were identified from a search of PubMed and Cochrane databases. Quality of selected studies was assessed using Jadad score for randomized placebo-controlled trials (RCT). Primary outcome was pain score reduction (30% and 50% reduction) and secondary outcome was patient global impression of change. Statistical analysis was performed using Review Manager 5.3. Results: Six international, multicenter, high-quality RCTs with 8-15 weeks duration of treatment met inclusion criteria. Four studies used different fixed dose (300 mg/d, 450 mg/d, 600mg/d) and 2 studies used titrated dose in evaluating the efficacy of pregabalin. There was statistically significant benefit of pregabalin over placebo in mean pain score reduction [odds ratio (OR) 1.81, 95% confidence interval (CI) 1.56-2.10 p < 0.00001 in fixed dose pregabalin 30% pain reduction; OR 2.06 95% CI 1.66-2.56 p < 0.00001 in fixed dose pregabalin 50% pain reduction; OR 1.53 95% CI 1.10-2.13 p 0.01 in titrated dose pregabalin 30% pain reduction; OR 1.80 95% CI 1.12-2.88 p 0.01 in titrated dose pregabalin 50% pain reduction]. Pregabalin also demonstrated significantly better patient global impression of change than placebo. No heterogeneity was seen in most groups. No publication bias was observed. Conclusion Our study showed pregabalin monotherapy was effective for pain treatment associated with fibromyalgia. Further studies with longer treatment duration are needed to confirm the long-term effectiveness of pregabalin for fibromyalgia treatment.

A systematic review summarizes the results of a number of individual studies that address a focused clinical question. It may be accompanied by a meta-analysis, which is a quantitative method of combining the results of all these studies in order to come up with a summary statistic of the overall effect of an intervention. Single studies may be unrepresentative of the total body of evidence, that is why combining the results of several studies in a systematic review increases precision, provides better estimates of effect, and includes a greater range of patients thus facilitating better clinical decision making. This must be done in a systematic and reproducible manner.

Background: The aim of this study was to determine the effectiveness of community-based programs in preventing dengue thru systematic review and meta-analysis of randomized control trials. Methods: All randomized control trials on the evaluation of the effectiveness of community-based programs in dengue prevention were searched on reliable databases (MEDLINE/PubMed, Embase, ClinicalTrials.gov, Google Scholar, etc.). From a total of 32 studies that were identified as of April 2021, there were 11 studies that were included after screening of the titles and abstracts by the review authors. A computer software Revman v.5.4 was used for the statistical analyses needed for the study. All the included studies were encoded in the said software and the effect of the interventions were estimated using odds ratio for the different measurable dengue indices along with an encoded 95% confidence interval Results: The community-based programs used in the included studies were generally effective in preventing dengue using House index (OR=0.83 (95% CI=0.70-0.98), p=0.03), Container index (OR=0.61 (95% CI=0.50-0.74), p<0.01) and Breteau index (OR=0.92 (95% CI=0.81-1.04), p=0.18) as the outcome of measure. The subgroup analysis showed that environmental manipulation [(HI: OR=0.59 (95% CI=0.37-0.92), p= 0.02); (CI: OR=0.54 (95% CI=0.20-1.44), p=0.22); (BI: OR=0.58 (95% CI=0.33-0.88), p=0.010)] had a greater effect towards dengue prevention as compared to human behavior alone or in combination with it. Conclusion We conclude that environmental management or programs involving community participation is an effective strategy in dengue prevention. Community empowerment and capacity building are indeed important elements to achieve dengue control.

Background: According to the American Heart Association, post- stroke patients often have neurologic deficits which can lead to a variety of complications. Patient-centered approach to care promotes shared decision-making between physicians and patients regarding treatment plan and may lead to better health outcomes for these post-stroke patients Objective: The effectiveness of patient-centered intervention in improving physical functioning among adult post-stroke patients with residual neurologic deficit was determined. Secondary outcomes such as improvement in social functioning, activities of daily living, quality of life and prevention of negative events such as death, re-hospitalization and depression were also evaluated Method: This systematic review included comparative randomized clinical trials involving humans as the clinical subjects, diagnosed to have had a stroke and appropriately evaluated to be in recovery with residual neurologic deficit, with the intervention described labeled as ‘patient-centered care’, and reporting an outcome on the improvement of physical functioning. Online search was done in Pubmed, CENTRAL, NICE, and the grey literature. Three reviewers independently conducted the search, appraisal and data extraction Results: Results varied depending on the outcome measurement tool utilized by the included studies. There was no difference between groups in terms of overall physical functioning and ADL as measured by SIS 16 and SIS 3.0. However, significant improvement was noted in the following subscales of SIS 3.0: hand movement (0.45,3.18, p=0.009, I2=0%), communication (0.86,2.16, p<0.00001, I2= 0%), and memory and thinking (0.13, 1.74, p=.02, I2= 33%). Physical function, ADL and social functioning using RNLI as an outcome (1.44-3.70] p<0.00001, I2= 0%), and physical functioning, social functioning, ADL and QOL as measured by participation (1.48, 3.74, p<0.00001, I2= 0%) and perception of recovery (2.22, 4.00, p<0.00001, I2=0%) also showed significant improvement Conclusion Patient-centered approaches have potential benefit in improving specific components of physical and social functioning, ADL and quality of life. However, differences in the type of patient-centered intervention and outcome measurement tools warrant further investigation into the specific interventions which will provide the most benefit to post-stroke patients
