IntroductionRecent studies have raised the concern on the risk of asthma in marijuana smokers; however, the results remain controversial and warrant further investigation. With a growing number of marijuana smokers, examining the association between marijuana smoking and asthma and quantifying such association through meta-analysis have important implications for public health and clinical decision-making. In view of this, the present protocol aims to detail a comprehensive plan of meta-analysis on the association aforementioned. The findings are expected to strengthen the current knowledge base pertaining to the potential adverse effects of marijuana smoking on pulmonary health and to facilitate the development of prevention strategies for asthma.Methods and analysisThe MEDLINE/PubMed, Web of Science and EMBASE databases will be searched systematically from inception to 1 September 2021 to retrieve the relevant observational studies focusing on the association between marijuana smoking and asthma. Both unadjusted and adjusted effect sizes, such as OR, relative risk, HR and the corresponding 95% CIs will be extracted for pooled analyses. Heterogeneity and publication bias across the included studies will be examined. The Newcastle-Ottawa Quality Scale will be used to assess the quality and risk of bias. Statistical software Review Manager V.5.3 and Stata V.11.0 will be used for statistical analyses.Ethics and disseminationSince no private and confidential patient data will be included in the reporting, approval from an ethics committee is not required. The results will be published in a peer-reviewed journal or disseminated in the relevant conferences. The study raises no ethical issue.OSF registration number10.17605/OSF.IO/UPTXC.

Objective: To evaluate the efficacy/effectiveness and safety of acupuncture for the treatment of hot flushes and its impact on serum hormone levels in menopausal women. Methods: A total of 10 databases were searched from their inception to August 2018. Reference lists of reviews and included articles were also hand-searched. Randomized controlled trials (RCTs) comparing the effect of acupuncture versus sham acupuncture, or acupuncture versus hormone therapy (HT), as treatment for menopausal hot flushes were included. Outcomes included hot flush frequency, hot flush severity and serum hormone levels of estradiol (E2), luteinizing hormone (LH) and follicle-stimulating hormone (FSH). Meta-analyses were performed using Review Manager 5.3 software. Results: Thirteen RCTs including 1784 patients were selected, seven of which were available for meta-analysis. Compared with sham acupuncture, acupuncture significantly decreased hot flush frequency (mean difference (MD) −0.84, 95% confidence interval (CI) [−1.64, −0.05], I2 = 54%) from baseline to the end of study, but did not impact end scores of hot flush frequency (MD 0.19, 95% CI [−0.61, 0.99], I2 = 0%) or severity (MD 0.02, 95% CI [−0.13, 0.17], I2 = 0%). No differences were found between acupuncture and HT in serum levels of E2 (MD 6.56, 95% CI [−3.77, 16.89], I2 = 76%), FSH (MD 1.06, 95% CI [−1.44, 3.56], I2 = 0%) or LH (MD −3.36, 95% CI [−13.37, 6.65], I2 = 89%). Conclusion: Acupuncture may not decrease hot flush frequency, but yet appears to have similar effects on serum hormone levels as HT, that is, increased E2 and decreased FSH and LH. Considering that no firm conclusions could be drawn due to the low quality and limited number of included trials included, further high-quality RCTs need to be conducted.

Anemia in pregnancy is anemia due to iron deficiency. The incidence of anemia in pregnant women ranges from 20% to 89%. As many as 40% of maternal deaths in developing countries are related to anemia in pregnancy and most often occur in developing countries, including Indonesia. In Indonesia, efforts made to overcome the problem of anemia in pregnant women are the administration of iron (Fe) tablets. This study aims to explain and analyse the relationship of adherence to Fe tablet consumption with anemia in pregnant women. This study uses a meta-analysis study. Researchers carried out research data collection by browsing online journals, using the Scopus and Google Scholar databases. In the meta-analysis process using the RevMan (Review Manager) 5.3 application, the results obtained Effect size (In Odds Ratio) of 2.44 (95% CI 1.30-4.60), which means that pregnant women who do not adhere to consuming Fe tablets have a risk 2.44 times affected by anemia compared to obedient pregnant women. There is a significant relationship between consuming Fe tablets and the incidence of anemia in pregnant women. Keywords: adherence, Fe tablets, anemia.

Background and Purpose Post-stroke fatigue is a debilitating and long-lasting condition. However, there are uncertainties regarding its prevalence and variability between studies. This review aims to estimate the prevalence of fatigue and determine the factors responsible for its variation in the literature. Methods A systematic review was conducted for all published studies (search to November 2020) using AMED, CINAHL, EMBASE, MEDLINE, PsycINFO, SCOPUS and Web of Science. Papers were included if they recruited participants with stroke, used a validated scale to measure fatigue and were in English. Two reviewers screened and assessed the relevant studies for eligibility ( n = 96). The included papers were appraised using the Joanna Briggs Institute (JBI) tool for prevalence studies, and data were extracted by one reviewer. To understand the variation in PSF prevalence between papers, data were pooled and analysed based on relevant methodological (e.g. time of assessment) or clinical factors (e.g. depression) using Review Manager 5.4 software. Results While 48 studies were included and summarised ( N = 9004), only 35 were appropriate for the meta-analysis ( N = 6851). The most frequently used tool to measure fatigue was the Fatigue Severity Scale (FSS) ( n = 31). The prevalence was calculated with a cut-off point of four or more using FSS and resulted in an estimate of 48% (95% CI 42–53%). Time of assessment (<6 vs ≥6 months), stroke type (ischaemic vs haemorrhagic/subarachnoid haemorrhage) and geographical location (East Asia vs Europe) could explain the prevalence variation between studies. Conclusions Fatigue is prevalent among stroke survivors. This condition varies in terms of occurrence between studies; however, time of assessment, stroke type and geographical location might explain this variation. As this review estimates the overall burden of fatigue after stroke, it provides a useful indicator to inform policy, planning and healthcare professionals. Further efforts are required to investigate the mechanisms that lead to PSF, particularly in the groups that show high prevalence, in order to prevent or alleviate it.

Background: N-acetyltransferase (NAT2) polymorphisms were reported to play important roles in antituberculosis-induced hepatotoxicity (ATDIH). However, the allelic types with increased risks for ATDIH were inconsistent as most studies are of a small sample size. Objective: The objective of the study was to conduct a meta-analysis to identify NAT2 alleles associated with increased risks of ATDIH. Methods: Studies reported on NAT2 polymorphism with the risk of ATDIH were searched systematically in PubMed, Scopus, and the World of Sciences. Studies were included if they fulfilled the inclusion criteria and excluded accordingly. Quality assessments were done using Newcastle-Ottawa Score. Statistical analysis was performed using Review Manager version 5.3. Cochrane Q-statistic test and I2 statistic were used to assess and quantify heterogeneity. Results: A total of 12 studies involving 580 cases and 3129 controls were included. NAT2 polymorphism was significantly associated with the risk of ATDIH with an odd ratio (OR) of 2.76 (1.86 – 4.10, 95% CI). Among the slow acetylators genotypes, NAT2*5/*7 carry the highest risk associated with ATDIH. Conclusion: NAT2 polymorphism was significantly associated with ATDIH.

ObjectiveTo compare the efficacy and safety of robotic-assisted adrenalectomy (RA) and standard laparoscopic adrenalectomy (LA) for pheochromocytoma (PHEO).MethodsWe systematically searched the Cochrane Library, PubMed, Embase, and Science databases for studies published through January 2021. Controlled trials on RA and LA for PHEOs were included. The meta-analysis was conducted with the Review Manager 5.4 software.ResultsFour studies with 386 patients were included in the analysis. There were no significant differences in OT (WMD: 0.16; 95% CI: -28.50 to 28.82; I2 = 89%; P = 0.99), transfusion rate (OR: 0.70; 95% CI: 0.07 to 7.07; I2 = 64%; P = 0.77), conversion rate (OR: 0.44; 95% CI: 0.07 to 2.88; I2 = 0%; P = 0.39), complication rate (OR: 1.06; 95% CI: 0.62 to 1.82; I2 = 0%; P = 0.84) among patients undergoing RA and LA. However, compared with patients who underwent LA, patients who underwent RA had a shorter LOS (OR: -0.50; 95% CI: -0.55 to 0.45; I2 = 31%; P&lt;0.01), less EBL (WMD: -0.85; 95% CI: -13.56 to -2.54; I2 = 44%; P&lt;0.01), and fewer IHD (OR: 0.34; 95% CI: 0.17 to 0.70; I2 = 0%; P&lt;0.01).ConclusionThe RA for pheochromocytoma achieve better outcomes over LA in terms of safety and efficacy.

Punch incision is an alternative to elliptical excision for treating epidermal inclusion cysts, but its efficacy has not been systematically reviewed. This study assessed the efficacy and safety of punch incision versus elliptical excision for epidermal inclusion cysts. Randomized controlled trials published through January 2021 that evaluated the performance of punch incision versus elliptical excision on epidermal inclusion cysts were identified through electronic databases and clinical registries. Version 2 of the Cochrane risk-of-bias tool for randomized trials tool was used. Review Manager software was used for the meta-analysis. Two trials (100 participants) were identified. The primary outcomes were recurrence rate (risk ratio, 2.40; 95% confidence interval [CI], 0.37–15.60 [favoring elliptical excision]), mean operative time (mean difference [MD], −5.28; 95% CI, −12.72 to 2.16 [favoring punch incision]), and mean postoperative wound length (MD, −11.67; 95% CI, −20.59 to −2.76 [favoring punch incision]). The evidence was low to moderate due to the small sample size and its considerable heterogeneity. The use of punch incision shortened the mean postoperative wound length and had comparable safety to that of elliptical excision.
