Globally, and in the United States (U.S.) specifically, rates of reported sexually transmitted infections (STIs) have been steadily increasing and are especially high among youth aged 13–25 years. Using condoms correctly and consistently is an effective STI prevention measure for sexually active youth, yet public health endeavors tend to focus only on condom use consistency. Directly measuring condom application is challenging and expensive. Alternative tools evaluate this behaviour, but little evidence exists on the appropriateness of these instruments in measuring application skills. This systematic review and meta-analysis examined the association between condom application skills and self-efficacy. We conducted a search of several databases as well as unpublished works. Studies were included if they were in English, examined youth aged 13–25 years, and were available between 1992 and 2019. The authors screened 630 titles and abstracts for initial inclusion criteria. A full-text review of 30 studies was conducted. The authors included 19 studies in the systematic review and 5 studies were included in the meta-analysis. Both a fixed- and random-effects model (Q = .2321, I2 = 0%) yielded a medium-sized statistically non-significant association (r = 0.217) between skills and self-efficacy. Despite the small sample size, findings suggest that skills and self-efficacy may not be as interchangeable as previously assumed when assessing condom application. Implications for future research are discussed.

AbstractThe aims of this systematic review and meta-analysis were to describe prevalence of cardiovascular disease in gout, compare these results with non-gout controls and consider whether there were differences according to geography. PubMed, Scopus and Web of Science were systematically searched for studies reporting prevalence of any cardiovascular disease in a gout population. Studies with non-representative sampling, where a cohort had been used in another study, small sample size (< 100) and where gout could not be distinguished from other rheumatic conditions were excluded, as were reviews, editorials and comments. Where possible meta-analysis was performed using random-effect models. Twenty-six studies comprising 949,773 gout patients were included in the review. Pooled prevalence estimates were calculated for five cardiovascular diseases: myocardial infarction (2.8%; 95% confidence interval (CI)s 1.6, 5.0), heart failure (8.7%; 95% CI 2.9, 23.8), venous thromboembolism (2.1%; 95% CI 1.2, 3.4), cerebrovascular accident (4.3%; 95% CI 1.8, 9.7) and hypertension (63.9%; 95% CI 24.5, 90.6). Sixteen studies reported comparisons with non-gout controls, illustrating an increased risk in the gout group across all cardiovascular diseases. There were no identifiable reliable patterns when analysing the results by country. Cardiovascular diseases are more prevalent in patients with gout and should prompt vigilance from clinicians to the need to assess and stratify cardiovascular risk. Future research is needed to investigate the link between gout, hyperuricaemia and increased cardiovascular risk and also to establish a more thorough picture of prevalence for less common cardiovascular diseases.

ObjectiveTo perform a systematic review of published literature on adrenal biopsy and to assess its performance in diagnosing adrenal malignancy.MethodsMedline In-Process and Other Non-Indexed Citations, MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trial were searched from inception to February 2016. Reviewers extracted data and assessed methodological quality in duplicate.ResultsWe included 32 observational studies reporting on 2174 patients (39.4% women, mean age 59.8 years) undergoing 2190 adrenal mass biopsy procedures. Pathology was described in 1621/2190 adrenal lesions (689 metastases, 68 adrenocortical carcinomas, 64 other malignancies, 464 adenomas, 226 other benign, 36 pheochromocytomas, and 74 others). The pooled non-diagnostic rate (30 studies, 2013 adrenal biopsies) was 8.7% (95%CI: 6–11%). The pooled complication rate (25 studies, 1339 biopsies) was 2.5% (95%CI: 1.5–3.4%). Studies were at a moderate risk for bias. Most limitations related to patient selection, assessment of outcome, and adequacy of follow-up. Only eight studies (240 patients) could be included in the diagnostic performance analysis with a sensitivity and specificity of 87 and 100% for malignancy, 70 and 98% for adrenocortical carcinoma, and 87 and 96% for metastasis respectively.ConclusionsEvidence based on small sample size and moderate risk of bias suggests that adrenal biopsy appears to be most useful in the diagnosis of adrenal metastasis in patients with a history of extra-adrenal malignancy. Adrenal biopsy should only be performed if the expected findings are likely to alter the management of the individual patient and after biochemical exclusion of catecholamine-producing tumors to help prevent potentially life-threatening complications.

Objective: The efficacy of mesenchymal stem cell (MSC) therapy in acetaminophen-induced liver injury has been investigated in animal experiments, but individual studies with a small sample size cannot be used to draw a clear conclusion. Therefore, we conducted a systematic review and meta-analysis of preclinical studies to explore the potential of using MSCs in acetaminophen-induced liver injury. Methods: Eight databases were searched for studies reporting the effects of MSCs on acetaminophen hepatoxicity. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were used. SYRCLE’s risk of bias tool for animal studies was applied to assess the methodological quality. A meta-analysis was performed by using RevMan 5.4 and STATA/SE 16.0 software. Results: Eleven studies involving 159 animals were included according to PRISMA statement guidelines. Significant associations were found for MSCs with the levels of alanine transaminase (ALT) (standardized mean difference (SMD) − 2.58, p < 0.0001), aspartate aminotransferase (AST) (SMD − 1.75, p = 0.001), glutathione (GSH) (SMD 3.7, p < 0.0001), superoxide dismutase (SOD) (SMD 1.86, p = 0.022), interleukin 10 (IL-10) (SMD 5.14, p = 0.0002) and tumor necrosis factor-α (TNF-α) (SMD − 4.48, p = 0.011) compared with those in the control group. The subgroup analysis showed that the tissue source of MSCs significantly affected the therapeutic efficacy (p < 0.05). Conclusion: Our meta-analysis results demonstrate that MSCs could be a potential treatment for acetaminophen-related liver injury.

Introduction: Rates of tPA administration remain low nationally and globally despite its demonstrated efficacy. We performed a systematic review and meta-analysis of interventions to increase the rate of tPA administration. Methods: We searched PubMed and EMBASE to identify all studies (excluding case reports) published between 1995 and January 8, 2015 documenting interventions to increase the utilization of tPA. We screened each study with pre-specified inclusion and exclusion criteria. Design elements and study data were extracted from eligible studies. The principal summary measure was the percentage change in rate of tPA administration. Fixed and random effects meta-analytic models were built to summarize the effect of intervention compared to control as well as intervention subtypes. Results: Our search yielded 1457 results of which 25 met eligibility criteria. We identified 13 pre-post studies and 11 randomized or quasi-experimental studies. Included studies utilized EMS (n=14), telemedicine (n=6), and public education (n=5). Intervention settings included urban (n=13), rural (n=4), and combined (n=4). In a fixed effect model, tPA administration was significantly higher in the intervention arm across all studies that limited enrollment to ischemic stroke patients (n=14) with a risk ratio (RR) of 1.71. Interventions involving EMS were associated with an increased rate of tPA administration with a RR of 1.51, (95% CI: 1.43-1.59, p<0.0001); promoting public education RR = 2.62, (95% CI: 1.54-4.43, p<0.01); and utilizing telemedicine RR = 2.97, (95% CI: 2.61-3.39, p<0.0001). Conclusions: Interventions to increase tPA use appear to have considerable efficacy. Comparative inferences between intervention types are limited by small sample size and intervention heterogeneity.

ObjectiveTo assess the effectiveness of heavy eccentric calf training (HECT) in comparison with natural history, traditional physiotherapy, sham interventions or other exercise interventions for improvements in pain and function in mid-portion Achilles tendinopathy.DesignA systematic review and meta-analysis were conducted as per the PRISMA guidelines.Data sourcesPUBMED, CINAHL (Ovid) and CINAHL (EBSCO) were searched from inception until 24 September 2018.Eligibility criteriaRandomised controlled trials comparing HECT to natural history, sham exercise, traditional physiotherapy and other exercise interventions were included. Primary outcome assessing pain and function was the Victorian Institute of Sports Assessment-Achilles.ResultsSeven studies met the inclusion criteria. This review suggests HECT may be superior to both natural history, mean difference (MD) (95% CI) of 20.6 (11.7 to 29.5, one study) and traditional physiotherapy, MD (95% CI) of 17.70 (3.75 to 31.66, two studies). Following removal of one study, at high risk of bias, due to pre-planned sensitivity analysis, this review suggests HECT may be inferior to other exercise interventions, MD (95% CI) of −5.65 (-10.51 to −0.79, three studies). However, this difference is unlikely to be clinically significant.ConclusionCurrent evidence suggests that HECT may be superior to natural history and traditional physiotherapy while HECT may be inferior to other exercise interventions. However, due to methodological limitations, small sample size and a lack of data we are unable to be confident in the results of the estimate of the effect, as the true effect is likely to be substantially different.Systematic review registryPROSPERO registration number: CRD4201804493Protocol referenceThis protocol has been published open access: Murphy M, Travers MJ, Gibson, W.

ABSTRACTObjective:Youth violence continues to trouble Canadians. Emergency department (ED) visits by youth after a violent injury may represent a “teachable moment,” and thus secondary violence prevention interventions may be effective. We conducted a systematic review to identify the success rates of any interventions, the populations likely to benefit and the outcome measures used.Data source:We searched 8 databases (i.e., MEDLINE, EMBASE, PubMed, CINAHL, the Cochrane Database of Systematic Reviews, the ACP Journal Club, DARE and CENTRAL).Study selection:Studies were included if they described and evaluated an intervention, were health care–based and targeted youth who were injured by violence. Two blinded investigators selected 15 articles from 181 abstracts. After full-text review, 8 articles were excluded, leaving 7 articles from 4 intervention programs.Data extraction:All interventions used ED case management of the violently injured patient. One randomized control trial (RCT) demonstrated a significant reduction in reinjury rates (treatment group 8.1% v. control group 20.3%,p= 0.05). Another small RCT found no statistically significant reductions in repeat violence or service use. One retrospective cohort study demonstrated a lower relative risk (RR) in future criminal justice involvement (RR = 0.67, 95% confidence interval 0.45–0.99). A retrospective study of pediatric patients with violent injuries found only 1% of these youth returned with injuries as a result of repeat violence.Data synthesis:Although all 4 case management interventions that we reviewed showed promise in the United States, small sample sizes and incomplete follow-up limited their ability to demonstrate significant decreases in reinjury.Conclusion:Future research is necessary to help EDs capitalize on the opportunity to effectively reduce youth violence.

BackgroundUp to 13% of psychiatric patients are readmitted shortly after discharge. Interventions that ensure successful transitions to community care may play a key role in preventing early readmission.AimsTo describe and evaluate interventions applied during the transition from in-patient to out-patient care in preventing early psychiatric readmission.MethodSystematic review of transitional interventions among adults admitted to hospital with mental illness where the study outcome was psychiatric readmission.ResultsThe review included 15 studies with 15 non-overlapping intervention components. Absolute risk reductions of 13.6 to 37.0% were observed in statistically significant studies. Effective intervention components were: pre- and post-discharge patient psychoeducation, structured needs assessments, medication reconciliation/education, transition managers and in-patient/out-patient provider communication. Key limitations were small sample size and risk of bias.ConclusionsMany effective transitional intervention components are feasible and likely to be cost-effective. Future research can provide direction about the specific components necessary and/or sufficient for preventing early psychiatric readmission.

ContextThe diagnostic accuracy of tests used to diagnose GH deficiency (GHD) in adults is unclear.ObjectiveWe conducted a systematic review and meta-analysis of studies that provided data on the available diagnostic tests.Data sourcesWe searched electronic databases (MEDLINE, EMBASE, Cochrane CENTRAL, Web of Sciences, and Scopus) through April 2011.Study selectionReview of reference lists and contact with experts identified additional candidate studies. Reviewers, working independently and in duplicate, determined study eligibility.Data extractionReviewers, working independently and in duplicate, determined the methodological quality of studies and collected descriptive, quality, and outcome data.Data synthesisTwenty-three studies provided diagnostic accuracy data; none provided patient outcome data. Studies had fair methodological quality, used several reference standards, and included over 1100 patients. Several tests based on direct or indirect stimulation of GH release were associated with good diagnostic accuracy, although most were assessed in one or two studies decreasing the strength of inference due to small sample size. Serum levels of GH or IGF1 had low diagnostic accuracy. Pooled sensitivity and specificity of the two most commonly used stimulation tests were found to be 95 and 89% for the insulin tolerance test and 73 and 81% for the GHRH+arginine test respectively. Meta-analytic estimates for accuracy were associated with substantial heterogeneity.ConclusionSeveral tests with reasonable diagnostic accuracy are available for the diagnosis of GHD in adults. The supporting evidence, however, is at high risk of bias (due to heterogeneity, methodological limitations, and imprecision).

Background:The relationship between obesity and pain remains unclear. The aim of this systematic review was to determine whether response to experimentally-evoked pain differed between obese and non-obese individuals. Studies that compared responses to experimentally-evoked pain between obese and non-obese human participants post-puberty (i.e.>16 years) were sought. Eligible studies published between January 1950 and May 2017 were identified by searching OVID, MEDLINE, EMBASE and Science Direct.Explanation:Methodological quality of included studies was assessed using the ‘QualSyst’ questionnaire. Of 1106 references identified only nine studies (683 participants) were eligible for review. Pressure pain was assessed in five studies and electrical pain in three studies. Two studies investigated thermal pain. Obesity was categorized according to body mass index (BMI) or as weight as a percentage of ideal body weight. Six of the nine included studies were of low methodological quality. There was a lack of extractable data to pool for meta-analysis of studies using thermal or electrical pain. A forest plot of data extracted from four studies on pressure pain threshold found no differences between obese and non-obese groups (overall effect size was Z=0.57, p=0.57).Conclusion:Small sample size was the main limitation in all studies. Participants with obesity were more sensitive to mechanical noxious stimuli than non-obese participants in three of five studies. However, overall, it was not possible to determine whether there are differences in pain sensitivity response to experimental stimuli between obese and non-obese individuals.

Introduction: Chronic hepatitis B (CHB) patients with metabolic syndrome (MetS) may present increased risk of liver-related outcomes (LROs) but prior studies were limited by small sample size and/or conflicting results. Using a systematic review and meta-analytic approach, we aimed to determine the association between MetS and LROs in CHB. Methods: Two researchers independently screened studies from the PubMed, Embase, Web of Science, and Cochrane Library databases from inception to January 21, 2020 and extracted the data. Estimates were pooled using a random-effects model. Results: We screened 2,228 articles and included 10 eligible studies (18,360 CHB patients, 2,557 with MetS). MetS was significantly associated with LROs overall (OR=2.45, 95%CI=1.39-4.32) but not the individual LRO components but subgroup analyses were limited by small study numbers. Discussion/Conclusion: MetS is associated with almost 3 folds higher risk of LROs in CHB and should be considered in management decisions. However, additional studies are needed.
