Journal of Science and Medicine in Sport Jan 2014To review the current research on alcohol-related violence and sports participation. (Review)
Review
OBJECTIVES
To review the current research on alcohol-related violence and sports participation.
METHODS
The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used to identify relevant studies for inclusion. A search of six databases (EBSCOhost) was conducted.
RESULTS
A total of 6890 studies was were identified in the initial search. Of these, 11 studies met the inclusion criteria. The majority of the studies were from the US (n=10) and focused on collegiate athletes (n=7), adolescents (n=3), professional/former professional athletes (n=1).
CONCLUSION
The reviewed research indicates higher rates of alcohol use and violence in athlete populations when compared against non-athlete populations. Masculinity, violent social identity and antisocial norms connected to certain sports stand out as potential factors that may impact the association between sport and violence in athlete populations.

Review
Sexual disorders such as erectile dysfunction (ED), sterility, and sexual inappetence represent some of the complex reproductive challenges that require addressing the underlying causes. The aim of this paper was to systematically synthesize literature on the ethnobotany, phytochemistry, bioactivities, and safety of plants used as remedies for managing sexual dysfunction and infertility, and improving fertility and virility in the EAC. Through an extensive review conducted in multidisciplinary electronic databases, 171 plant species were identified to have been reported for the management of sexual inappetence (i.e., used as aphrodisiacs, 39.4%), ED (35.9%), infertility (18.7%), and increasing fertility (6.0%). The most used plants are , , , , , , and while roots (44.9%), leaves (21.8%), stem and root barks (16.7%) of shrubs (35%), trees (31%), herbs (26%), and climbers (8%) are the preferred organs for making decoctions (69%). The research strides to date indicate that , , , , , , and have been assessed for their bioactivity. The majority (71.4%) of the plants either increased testosterone levels and mounting frequency or elicited prosexual stimulatory effects in male rats. More studies investigating the relevant pharmacological activities (aphrodisiac, fertility, and phosphodiesterase-5 inhibitory activities), safety aspects, responsible compounds, and clinical studies are warranted to establish the pharmacological potential of the unstudied species and elucidate the mechanism of action of the bioactive compounds.

Meta-Analysis
BACKGROUND
Congenital adrenal hyperplasia (CAH) is an autosomal recessive genetic disorder that causes defects in the adrenal cortex enzymes that impair the biosynthesis of cortisol, aldosterone, or both. The most common type is the 21-hydroxylase enzyme deficiency in approximately 95% of cases resulting from CYP21A2 gene mutations or deletions.
OBJECTIVES
This study aimed to systematically review the national differences in CAH incidence and analyze the pooled results to determine disparities and whether ethnicity can predispose people to develop CAH.
METHODS
PubMed, Scopus, and LILACS were used to achieve results until June 22, 2018. Study eligibility criteria included availability of full-text; English, Spanish, or Portuguese languages; incidence or number of new cases; and number of live births or sample population. Only the classic CAH type (salt-wasting and simple-virilizing) was considered, and no distinction was made between the enzyme deficiency types.
RESULTS
This study summarizes the findings of 58 studies and 31 countries (from 1969 to 2017), in which the overall CAH incidence was 1:9,498 (95% confidence interval: 1:9,089, 1:9,945). Countries from the Eastern Mediterranean and Southeast Asia revealed the highest CAH incidence. The lowest incidence was reported in countries of the Western Pacific of Asia. No remarkable difference was observed in the Hispanics/Latino and White groups. However, they manifested a higher incidence of CAH than people identified as Black or of African descent. Published studies on CAH incidence in the sub-Saharan African region and parts of Europe were insufficient.
CONCLUSIONS
This study highlights the at-risk population for CAH and regions that need monitoring for CAH. The highest CAH incidence could be attributed to higher consanguinity, less genetic diversity, or other genetic causes since CAH is an inherited genetic disorder. Cultural practices in some places regarding consanguineous unions or geographic isolation may directly affect the incidence. Newborn screening for CAH may be unavailable in many developing countries, thereby affecting the actual CAH incidence. Therefore, healthcare workers should be trained to recognize CAH at an early stage to reduce its complications and mortality.

Meta-Analysis
BACKGROUND
An increased prevalence of functional hyperandrogenism-including polycystic ovary syndrome (PCOS)-has been described in women with type 1 diabetes (T1D). However, heterogeneity between studies is frequent, and prevalence rates vary according to different criteria used for the diagnosis of PCOS and the population studied.
OBJECTIVE AND RATIONALE
We aimed to perform a systematic review and meta-analysis of the prevalence of PCOS and related hyperandrogenic traits in premenopausal women with T1D. This way, we intend to increase the precision of the estimates of prevalence of PCOS and related traits in women with T1D, and to explore sources of heterogeneity while providing prevalence estimates for clinically relevant subgroups such as the different phenotypes.
SEARCH METHODS
We conducted a systematic review of the literature using Medline-OVID and Embase databases (Open Science Framework registry for systematic review protocols, https://osf.io/6cv9p/). Studies published up to 29 March 2021 were considered. We selected cross-sectional or prospective studies that reported, in patients with T1D, prevalence data on PCOS according to current definitions and different phenotypes, and/or prevalence rates of other related traits (hirsutism, hyperandrogenaemia, oligo-amenorrhoea and/or polycystic ovarian morphology: PCOM). Exclusion criteria for the review were studies addressing types of diabetes other than T1D; and studies using diagnostic definitions of PCOS different than those mentioned above. Two independent researchers performed data extraction. To assess the risk of bias, we used a tool developed specifically to appraise population-based prevalence studies.
OUTCOMES
We selected 19 studies (1042 women) reporting the prevalence of PCOS and/or other hyperandrogenic traits. Regarding bias, 12 studies were considered of low-risk, and the remaining seven studies were considered intermediate risk. The pooled prevalence of PCOS when considering all possible phenotypes (ESHRE- American Society for Reproductive Medicine criteria) in T1D was 26% (95% CI: 19-34%; 13 studies, 684 women). Pooled prevalence of classic PCOS (US National Institutes of Health criteria) was 16% (95% CI: 10-22%; 9 studies, 614 women). Pooled prevalence of hyperandrogenic PCOS (Androgen Excess and PCOS Society criteria) was 26% (95% CI: 16-41%; 5 studies, 329 women). Hirsutism (24%), hyperandrogenaemia (29%), oligomenorrhoea (24%) and PCOM (34%) were also prevalent. Heterogeneity was high in almost all these meta-analyses.
WIDER IMPLICATIONS
This systematic review and meta-analysis showed that PCOS and related hyperandrogenic traits are present in approximately one in every four women with T1D. Larger studies are needed to confirm this association, to address the effect of different variables on the occurrence of PCOS.

Review
Colorectal cancer (CRC) is highly preventable when CRC screening is utilized, yet CRC screening completion among African American men is relatively low and their mortality rates remain 50% higher juxtaposed to their White counterparts. Since a growing body of literature indicates masculinity, racism, and social support each have strong influences on CRC screening uptake, this systematic review examined the connections between these three sociocultural factors and CRC screening uptake among African American men. Potential studies were retrieved from MEDLINE, CINAHL, EMBASE, and PsycINFO. Cited reference searching for the final sample was employed to identify and assess additional studies for inclusion using Scopus. The methodological quality of the reviewed evidence was also evaluated. Nineteen studies met inclusion/exclusion criteria. Thirteen studies employed nonexperimental research designs; a quasi-experimental design was present in four, and two utilized experimental designs. Studies were published between 2000 and 2014; the majority between 2009 and 2013. Social support was most frequently addressed (84%) while masculinity and racism were equally studied with paucity (11%) for their influence on CRC screening. After evaluating conceptual and methodological characteristics of the studies, 42% fell below average in quality and rigor. The need for increased attention to the sociocultural correlates of CRC screening for African American men are highlighted in this systematic review, and important recommendations for research and practice are provided. Alongside a call for more rigorous research, further research examining the influence of masculinity and racism on CRC screening completion among African American men is warranted.

Review
BACKGROUND
Hegemonic masculinity has been recognized as contributing to the perpetration of different forms of gender-based violence (GBV). Abandoning hegemonic masculinities and promoting positive masculinities are both strategies used by interventions that foreground a "gender-transformative approach." Preventing GBV among young people could be strengthened by engaging young men. In this article, we aim to systematically review the primary characteristics, methodological quality, and results of published evaluation studies of educational interventions that aim to prevent different forms of GBV through addressing hegemonic masculinities among young people.
MAIN BODY
We conducted a systematic review of available literature (2008-2019) using Medline (PubMed), Scopus, Web of Science, PsycInfo, the CINAHL Complete Database, and ERIC as well as Google scholar. The Template for Intervention Description and Replication was used for data extraction, and the quality of the selected studies was analyzed using the Mixed Method Appraisal Tool. More than half of the studies were conducted in Africa ( = 10/15) and many were randomized controlled trials ( = 8/15). Most of the studies with quantitative and qualitative methodologies ( = 12/15) reported a decrease in physical GBV and/or sexual violence perpetration/victimization ( = 6/15). Longitudinal studies reported consistent results over time.
CONCLUSIONS
Our results highlight the importance of using a gender-transformative approach in educational interventions to engage young people in critical thinking about hegemonic masculinity and to prevent GBV.

Meta-Analysis Review
BACKGROUND
Sexual dimorphism manifests noticeably in obesity-associated gonadal dysfunction. In women, obesity is associated with androgen excess disorders, mostly the polycystic ovary syndrome (PCOS), whereas androgen deficiency is frequently present in obese men in what has been termed as male obesity-associated secondary hypogonadism (MOSH). Obesity-associated gonadal dysfunction, consisting of PCOS in women and MOSH in men, is a frequent finding in patients with severe obesity and it may be ameliorated or even resolve with marked weight loss, especially after bariatric surgery.
OBJECTIVE AND RATIONALE
We aimed to obtain an estimation of the prevalence of obesity-associated gonadal dysfunction among women and men presenting with severe obesity and to evaluate the response to bariatric surgery in terms of resolution and/or improvement of this condition and changes in circulating sex hormone concentrations.
SEARCH METHODS
We searched PubMed and EMBASE for articles published up to June 2016. After deleting duplicates, the abstract of 757 articles were analyzed. We subsequently excluded 712 articles leaving 45 studies for full-text assessment of eligibility. Of these, 16 articles were excluded. Hence, 29 studies were included in the quantitative synthesis and in the different meta-analyses. Quality of the studies was assessed using the Quality index for prevalence studies and the Quality Assessment Tool for Before-After (Pre-Post) Studies With No Control Group available from the National Heart, Lung and Blood Institute. For meta-analyses including more than 10 studies, we used funnel and Doi plots to estimate publication bias.
OUTCOMES
In severely obese patients submitted to bariatric surgery, obesity-associated gonadal dysfunction was very prevalent: PCOS was present in 36% (95CI 22-50) of women and MOSH was present in 64% (95CI 50-77) of men. After bariatric surgery, resolution of PCOS was found in 96% (95CI 89-100) of affected women and resolution of MOSH occurred in 87% (95CI 76-95) of affected men. Sex hormone-binding globulin concentrations increased after bariatric surgery in women (22 pmol/l, 95CI 2-47) and in men (22 pmol/l, 95CI 19-26) and serum estradiol concentrations decreased in women (-104 pmol/l, 95CI -171 to -39) and to a lesser extent in men (-22 pmol/l, 95CI -38 to -7). On the contrary, sex-specific changes were observed in serum androgen concentrations: for example, total testosterone concentration increased in men (8.1 nmol/l, 95CI 6-11) but decreased in women (-0.7 nmol/l, 95CI -0.9 to -0.5). The latter was accompanied by resolution of hirsutism in 53% (95CI 29-76), and of menstrual dysfunction in 96% (95CI 88-100), of women showing these symptoms before surgery.
WIDER IMPLICATIONS
Obesity-associated gonadal dysfunction is among the most prevalent comorbidities in patients with severe obesity and should be ruled out routinely during their initial diagnostic workup. Considering the excellent response regarding both PCOS and MOSH, bariatric surgery should be offered to severely obese patients presenting with obesity-associated gonadal dysfunction.

Frontiers in Endocrinology 2024To evaluate the effects of behavioral intervention for polycystic ovary syndrome (PCOS). (Meta-Analysis)
Meta-Analysis
The effects of behavioral intervention on anthropometric, clinical, and biochemical parameters in patients with polycystic ovary syndrome: a systematic review and meta-analysis.
OBJECTIVE
To evaluate the effects of behavioral intervention for polycystic ovary syndrome (PCOS).
METHODS
Electronic databases were searched, including Pubmed, Medline, EMBASE, and the Cochrane Central Register of Controlled Trials from inception to 1 April 2023. Inclusion criteria for this study required a diagnosis of PCOS. Interventions of interest included behavioral intervention and routine treatment compared with routine treatment. The studies included in the analysis were designed as randomized controlled trials (RCTs). We conducted meta-analyses following the recommended guidelines. The data was analyzed using either the random effects model or fixed effects model. The results of the studies were expressed as either mean differences (MD) or standardized mean differences (SMD) along with their corresponding 95% confidence intervals (CIs).
RESULTS
Eight RCTs were identified, including data from 744 patients (415 in the intervention group and 329 in the control group). The results indicate an improvement in the effectiveness of behavioral interventions for weight loss (MD: -1.07; 95% CI: -2.1 to 0.03; I = 0%; P=0.04), body mass index (BMI) (MD: -1.12; 95% CI: -1.92 to -0.33; I = 73%; P=0.006), waist circumference (MD: -3.97; 95% CI: -5.64 to -2.29; I = 0%; P<0.00001), quality of life about weight (MD: 0.58; 95% CI: 0.15 to 1.02; I = 0%; P=0.008), depression (SMD: -1.12; 95% CI: -2.35 to -0.07; I = 92%; P=0.04), and triglycerides (MD: -0.16; 95% CI: -0.27 to -0.05; I = 27%; P=0.004). However, there were no significant differences in menstrual cycles, hirsutism, emotions, and infertility. The study also found that behavioral interventions had no significant effect on systolic and diastolic blood pressure, high-density lipoprotein, low-density lipoprotein, homeostasis model assessment of insulin resistance, testosterone, total cholesterol, fasting glucose, fasting insulin, hemoglobin A1C, and sex hormone binding globulin.
CONCLUSION
Behavioral intervention supplementation contributes to weight loss, reduction in BMI and waist circumference, and improvement in depression among patients with PCOS. However, no significant improvement was observed in the biochemical index and quality of life. The long-term effects of behavioral intervention for PCOS remain unclear due to limitations in the quality of the studies involved and the short duration of treatment.

Meta-Analysis
AIMS
Due to its high heterogenicity and unclear etiology, there is currently no specific treatment for polycystic ovary syndrome (PCOS). Metformin, as an insulin sensitizer, combined with spironolactone, an antiandrogen medication, may exert complementary effects on PCOS. We therefore performed a meta-analysis of trials in which metformin combined with spironolactone was applied to treat PCOS to evaluate the efficacy and safety of the combination therapy.
METHODS
We retrieved the PubMed, Embase, Scopus, Cochrane Library, CNKI, CBM, Wangfang, and VIP databases for literatures published from their inception to December 16, 2022 on the effects of metformin combined with spironolactone in the treatment of PCOS. Inclusion criteria according to P.I.C.O.S criteria were: PCOS patients, metformin combined with spironolactone interventions, metformin alone control group, and randomized controlled trials with the following outcome data: body mass index (BMI), hirsutism score, luteinizing hormone (LH), follicle-stimulating hormone (FSH), total testosterone (TT), fasting blood glucose (FBG), Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), and side effects including nausea, vomiting, diarrhea and drug withdrawal.
RESULTS
Our results revealed that metformin combined with spironolactone significantly reduced BMI and TT, but that it exerted no significant effects on hirsutism score, or on FSH or LH concentrations. Combined treatment also resulted in a significant diminution in FBG and insulin resistance using the HOMA-IR when the interventional time was greater than 6 months. In addition, the combination did not have a higher occurrence of adverse reactions than metformin alone.
CONCLUSION
Compared with metformin alone, metformin combined with spironolactone therapy may be more effective in reducing BMI and serum androgen levels, but the combination showed no significant effect on the hirsutism score or gonadotropin hormone levels, and was not associated with an elevation in side-effects. Moreover, when the treatment course was greater than 6 months, combination therapy reduced FBG and improved insulin resistance more effectively than metformin alone. However, more research is needed to determine the most effective course of treatment.

Review
UNLABELLED
The history of South Africa is embedded in violence. Exposure to various forms of violence is a consistent experience of children, adolescents, and young people in this context, negatively impacting various aspects of their lives and overall quality of life. However, these experiences of violence have been narrated from an adult-centric perspective. The current study thus aims to systematically review and synthesis existing empirical studies focusing on youth and adolescents' perceptions of violence in post-apartheid South Africa. We identified 34 articles that were included in the final review, with study samples ranging from youth and adolescents between the ages of 8 to 27-years-old. The included studies were delineated into three overarching themes using thematic analysis, namely: ; ; and . We found several contributing factors that resulted in violence, such as: low socio-economic conditions, hegemonic masculinity, and male entitlement over women; which can be linked to the corollaries of apartheid. At a grassroots level, more research is needed to gain deeper knowledge about how youth and adolescents understand, conceptualise, and contextualise violence through various frameworks. Moreover, violence prevention and intervention requires a collaborative approach to exact meaningful change that will be beneficial for all stakeholders.
