Abstract Rationale Aggression and irritability are notable psychiatric side effects of anabolic-androgenic steroid (AAS) use. However, no previous study has systematically reviewed and quantitatively synthesized effects reported by experimental studies on this topic. Objective We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) investigating the effect of AAS administration on self-reported and observer-reported aggression. Methods Twelve RCTs comprising a total of 562 healthy males were identified through systematic searches of MEDLINE, PsycInfo, ISI Web of Science, ProQuest, Google Scholar, and the Cochrane Library. Results After excluding one outlier, AAS administration was associated with an increase in self-reported aggression under a random-effects model, albeit small (Hedges’ g = 0.171, 95% CI: 0.029–0.312, k = 11, p = .018), and when restricting the analysis to the effect of acute AAS administration on self-reported aggression under a fixed-effect model (g = 0.291, 95% CI: 0.014–0.524, p = .014). However, the above effects were neither replicated in the analysis of observer-reported aggression nor after restricting the analysis to the effects of the administration of higher (over 500 mg) and long-term (3 days to 14 weeks) doses. Conclusions The present meta-analysis provides evidence of an increase, although small, in self-reported aggression in healthy males following AAS administration in RCTs. Ecologically rational RCTs are warranted to better explore the effect of AAS administration on aggression in humans.

Background: Evidence is needed on the effectiveness of wearing face masks in the community to prevent SARS-CoV-2 transmission.Methods: Systematic review and meta-analysis to investigate the efficacy and effectiveness of face mask use in a community setting and to predict the effectiveness of wearing a mask. We searched MEDLINE, EMBASE, SCISEARCH, The Cochrane Library, and pre-prints from inception to 22 April 2020 without restriction by language. We rated the certainty of evidence according to Cochrane and GRADE approach.Findings: Our search identified 35 studies, including three randomized controlled trials (RCTs) (4,017 patients), 10 comparative studies (18,984 patients), 13 predictive models, nine laboratory experimental studies. For reducing infection rates, the estimates of cluster-RCTs were in favor of wearing face masks vs. no mask, but not at statistically significant levels (adjusted OR 0.90, 95% CI 0.78–1.05). Similar findings were reported in observational studies. Mathematical models indicated an important decrease in mortality when the population mask coverage is near-universal, regardless of mask efficacy. In the best-case scenario, when the mask efficacy is at 95%, the R0 can fall to 0.99 from an initial value of 16.90. Levels of mask filtration efficiency were heterogeneous, depending on the materials used (surgical mask: 45–97%). One laboratory study suggested a viral load reduction of 0.25 (95% CI 0.09–0.67) in favor of mask vs. no mask.Interpretation: The findings of this systematic review and meta-analysis support the use of face masks in a community setting. Robust randomized trials on face mask effectiveness are needed to inform evidence-based policies.PROSPERO registration: CRD42020184963.

Introduction: The surgical treatment of hallux valgus presents several techniques described in the literature. Recently, the percutaneous technique has appeared as a less invasive option in the correction of the deformity and is increasingly used by surgeons.  Methods: A meta-analysis was performed using studies discovered by the systematic review of articles included in electronic databases (Medline, Scopus, Embase and the Cochrane Library) until June 2018 (Systematic Review Registry PROSPERO: CRD42018096613). A pooling analysis was synthesized from clinical outcomes such as the visual analogue scale of pain (VAS) and AOFAS score, radiographic outcomes and evaluation of complications.  Results: Two studies, including 137 feet with a hallux valgus diagnosis were added to the analysis, comparing open surgery using the Scarf and Akin (SA) technique versus percutaneous Chevron and Akin (PECA). In the synthesis of the results, pain in the perioperative period was lower in the PECA group, with a reduction of 1.68 points in the fixed effect model (95% CI = -2.09 a -1.27, p < 0.01, i2 = 87%, t2 = 0.60). There were no differences between techniques in the radiographic results or in the risk of complications. The PECA technique demonstrated a longer radioscopy time compared with SA. Conclusion: Use of the PECA method to correct hallux valgus compared with the open SA technique demonstrated less pain in the perioperative period, a similar potential for radiographic correction and an equal risk of complications, with a longer radioscopy time.

Abstract Obesity has been shown to intensify the decline of physical function and lead to frailty. Nutrition is an important method in managing obesity and frailty, while seldom reviews have ever explored the effects of nutritional education interventions. We conducted a systematic review (PROSPERO: CRD42019142403) to explore the effectiveness of nutritional education interventions in managing body composition and physio-psychosocial parameters related to frailty. Randomized controlled trials and quasi-experimental studies were searched in CINAHL, Cochrane Library, EMBASE, MEDLINE, PsycINFO, PubMed and Scopus from 2001 to 2019. Hand search for the reference lists of included papers was conducted as well. We assessed the quality of included studies by Cochrane risk of bias tool. Meta-analyses and narrative synthesis were used to analyse the data. Two studies with low risk of bias were screened from 180 articles, which involved 177 older people with an average age of 69.69±4.08 years old. The results showed that nutritional education was significantly effective in reducing body weight and fat mass than exercises, and it was beneficial to enhancing physical function and psychosocial well-being. But the effects of nutritional education in increasing muscle strength were not better than exercises. The combined effects of nutritional education and exercises were superior than either exercises or nutritional education interventions solely in preventing the loss of lean mass and bone marrow density, and in improving physical function. Due to limited numbers of relevant studies, the strong evidence of effectiveness of nutritional education interventions on reversing frailty is still lacking.

Aims To investigate the association between TBI and stroke risk. Summary of review We undertook a systematic review of MEDLINE, EMBASE, CINAHL, and The Cochrane Library from inception to 4th December 2020. We used random-effects meta-analysis to pool hazard ratios (HR) for studies which reported stroke risk post-TBI compared to controls. Searches identified 10,501 records; 58 full texts were assessed for eligibility and 18 met the inclusion criteria. The review included a large sample size of 2,606,379 participants from four countries. Six studies included a non-TBI control group, all found TBI patients had significantly increased risk of stroke compared to controls (pooled HR 1.86; 95% CI 1.46-2.37). Findings suggest stroke risk may be highest in the first four months post-TBI, but remains significant up to five years post-TBI. TBI appears to be associated with increased stroke risk regardless of severity or subtype of TBI. There was some evidence to suggest an association between reduced stroke risk post-TBI and Vitamin K antagonists and statins, but increased stroke risk with certain classes of antidepressants. Conclusion TBI is an independent risk factor for stroke, regardless of TBI severity or type. Post-TBI review and management of risk factors for stroke may be warranted.

This systematic review and meta-analysis investigated whether the use of a lumbar roll reduced forward head posture (FHP) while sitting among individuals with or without musculoskeletal disorders. EMBASE, MEDLINE, and the Cochrane Library were systematically searched from their inception to August 2020. The quality of evidence for variables used in the meta-analysis was determined using the GRADE system. Five studies satisfied the criteria for data analysis. All studies included individuals without any spinal symptoms. Data from five studies on neck angle showed a statistically significant (p = 0.02) overall effect (standardized mean difference (SMD) = 0.77), indicating a lesser neck flexion angle while sitting with a lumbar roll than without it. Data from two studies on head angle showed a statistically significant (p = 0.04) overall effect (SMD = 0.47), indicating a lesser head extension angle while sitting with a lumbar roll than without it. In each meta-analysis, the quality of evidence was very low in the GRADE system. The use of a lumbar roll while sitting reduced FHP among individuals without spinal symptoms.

Abstract Aim This systematic review and meta-analysis aims to assess this relationship and determine the most appropriate age for recommendation of surgery. Method According to the “Preferred Reporting items for systematic review and meta-analysis” (PRISMA) statement, a literature search was performed across Medline, EMBASE and the Cochrane library from 1946-2018. Articles examining a relationship between age and myringoplasty or type 1 tympanoplasty success rates were screened. Results 20 articles encompassing data from 2244 procedures were included. The overall results conveyed a clear correlation between increasing age and rising success rate. A t-test was conducted which demonstrated a significant (P = 0.05) transition at aged 10, whereby success rate below age 10 was 70.6% and above 10 was 86%. Conclusions This systematic review and meta-analysis has uncovered a clear correlation between increasing age and increasing success rate for myringoplasty in the paediatric population. Furthermore, a significant transitional point has been demonstrated at the age of 10 and We hope that knowledge of increased success rates particularly after the age of 10 helps clinicians make more informed decisions about when to operate

Objective. The objective of this study was to conduct a systematic review to assess the effectiveness and safety of traditional Chinese herb combined with surgery for male varicocele infertility compared to surgery.Methods. Randomized controlled trials (RCTs) data of traditional Chinese herbs combined with surgery for male varicocele fertility versus surgery were collected by searching the Cochrane Library, Embase, PubMed, and Chinese databases. The risk of bias was assessed using Cochrane Handbook. Study outcomes were presented as risk ratios (RRs) for dichotomous data.Results. Seventeen of 72 potentially relevant trials met the inclusion criteria. The methodological qualities of the RCTs were low. Compared with the surgery group, the traditional Chinese herb combined with surgery group had superiority in pregnancy rate at 3-month (RR=1.76, andP=0.008), 6-month (RR=1.58, andP=0.0005), and 2-year (RR=1.58, andP=0.0005) follow-ups. No RCT was found to describe the side effects.Conclusion. On considering the low methodological quality of RCTs, there was no enough evidence on traditional Chinese herb with surgery for male varicocele infertility, and more high-quality RCTs of large sample sizes are required.

Intelligence Development

There is a deep-rooted correlation between refractory epilepsy in pediatric age and intelligence development. However, little is known about whether surgical procedures used in pediatric epilepsy treatment can affect Intelligence Quotient (IQ) or not. Factors that might influence postoperative IQ are also a matter of study in several articles. To tackle these issues, a systematic review with meta-analysis was conducted with the terms “epilepsy”, “epileptic”, “surgery”, “surgical”, “Wechsler Scale” and “intelligence tests” in PubMed, the Cochrane Library, EMBASE and Clinical Trials.gov. A descriptive data synthesis was carried out to address each of the objectives and then a metaanalysis using a random effects model was conducted. A meta-regression was performed to ascertain possible factors that could influence postoperative IQ. The meta-analysis of the studies included found a mean difference between postoperative and preoperative full-scale IQ values of 1.014 standardized points (p < 0.001). Among all the articles regarding curative surgeries, only three reported an overall significant improvement in IQ after surgery. Regarding palliative procedures, both studies with anterior corpus callosotomy reported a significant improvement in full-scale IQ values two years after surgery. The meta-regression performed did not find any predictors of change in full-scale IQ.

Abstract Background Evidence on follow-up duration for patients with sporadic pheochromocytomas is absent, and current guidelines of the European Society of Endocrinology, American Association of Clinical Endocrinologists and Endocrine Surgeons, and the Endocrine Society are ambiguous about the appropriate duration of follow-up. The aim of this systematic review and meta-analysis is to evaluate the recurrence rate of sporadic pheochromocytomas after curative adrenalectomy. Materials and Methods A literature search in PubMed, Embase, and the Cochrane Library was performed. A study was eligible if it included a clear report on the number of sporadic patients, recurrence rate, and follow-up duration. Studies with an inclusion period before 1990, &lt;2 years of follow-up, &lt;10 patients, and unclear data on the sporadic nature of pheochromocytomas were excluded. A meta-analysis on recurrence was performed provided that the heterogeneity was low (I2 &lt; 25%) or intermediate (I2 26–75%). Hozo’s method was used to calculate weighted mean follow-up duration and weighted time to recurrence with combined standard deviations (SDs). Results A total of 13 studies, including 430 patients, were included in the synthesis. The meta-analysis results describe a pooled recurrence rate after curative surgery of 3% (95% confidence interval: 2–6%, I2 = 0%), with a weighted mean time to recurrence of 49.4 months (SD = 30.7) and a weighted mean follow-up period of 77.3 months (SD = 32.2). Conclusions This meta-analysis shows a very low recurrence rate of 3%. Prospective studies, including economical and health effects of limited follow-up strategies for patients with truly sporadic pheochromocytomas should be considered.
