Review
BACKGROUND
Racism constitutes a barrier towards achieving equitable healthcare as documented in research showing unequal processes of delivering, accessing, and receiving healthcare across countries and healthcare indicators. This review summarizes studies examining how racism is discussed and produced in the process of delivering, accessing and receiving healthcare across various national contexts.
METHOD
The PRISMA guidelines for scoping reviews were followed and databases were searched for peer reviewed empirical articles in English across national contexts. No starting date limitation was applied for this review. The end date was December 1, 2020. The review scoped 213 articles. The results were summarized, coded and thematically categorized in regards to the aim.
RESULTS
The review yielded the following categories: healthcare users' experiences of racism in healthcare; healthcare staff's experiences of racism; healthcare staff's racial attitudes and beliefs; effects of racism in healthcare on various treatment choices; healthcare staff's reflections on racism in healthcare and; antiracist training in healthcare. Racialized minorities experience inadequate healthcare and being dismissed in healthcare interactions. Experiences of racism are associated with lack of trust and delay in seeking healthcare. Racialized minority healthcare staff experience racism in their workplace from healthcare users and colleagues and lack of organizational support in managing racism. Research on healthcare staff's racial attitudes and beliefs demonstrate a range of negative stereotypes regarding racialized minority healthcare users who are viewed as difficult. Research on implicit racial bias illustrates that healthcare staff exhibit racial bias in favor of majority group. Healthcare staff's racial bias may influence medical decisions negatively. Studies examining healthcare staff's reflections on racism and antiracist training show that healthcare staff tend to construct healthcare as impartial and that healthcare staff do not readily discuss racism in their workplace.
CONCLUSIONS
The USA dominates the research. It is imperative that research covers other geo-political contexts. Research on racism in healthcare is mainly descriptive, atheoretical, uses racial categories uncritically and tends to ignore racialization processes making it difficult to conceptualize racism. Sociological research on racism could inform research on racism as it theoretically explains racism's structural embeddedness, which could aid in tackling racism to provide good quality care.

Comparative effectiveness of various physical exercise interventions on executive functions and related symptoms in children and adolescents with attention deficit hyperactivity disorder: A systematic review and network meta-analysis.
BACKGROUND
Physical exercise has been recommended as an important nonpharmacological therapeutic strategy for managing attention deficit hyperactivity disorder (ADHD). We conducted a network meta-analysis (NMA) to assess the comparative impact of different physical exercise modalities on enhancing executive functions (EFs) and alleviating symptoms in children and adolescents with ADHD.
METHODS
We searched Web of Science, PubMed, Embase, Cochrane Central Register of Controlled Trials, SPORTDiscus, PsycINFO, CNKI, and clinical trials databases from inception to October 20, 2022. Randomized controlled trials (RCTs) and quasi-experimental studies investigating physical exercise for ADHD-related symptoms of hyperactivity/impulsivity and inattention, and executive functions were included. The frequentist random-effect NMA method was applied to pool the results.
RESULTS
A total of 59 studies (including 39 RCTs, 5 quasi-RCTs, and 15 self-controlled trials) published between 1983 and 2022 were incorporated into the systematic review, of which 44 studies with 1757 participants were eligible for meta-analysis. All types of physical exercise were effective in improving EFs (SMD = 1.15, 95% CI: 0.83 to 1.46), and open-skill activities which require participants to react in a dynamically changing and externally paced environment induced the most incredible benefits for executive functions (SUCRA = 98.0%, SMD = 1.96, and 95% CI: 1.15 to 2.77). Subgroup analyses for EFs revealed varied findings that open-skill activities were the most promising physical exercise type for improving inhibitory control (SUCRA = 99.1%, SMD = 1.94, and 95% CI: 1.24 to 2.64), and closed-skill activities dominated by aerobic exercises had a slightly higher probability of being the most promising physical exercise intervention for working memory (SUCRA = 75.9%, SMD = 1.21, and 95% CI: -0.22 to 2.65), and multicomponent physical exercise tended to be the most effective in cognitive flexibility (SUCRA = 70.3%, SMD = 1.44, and 95% CI: -0.19 to 3.07). Regarding ADHD-related symptoms, closed-skill activities dominated by aerobic exercises might be more advantageous for hyperactivity/impulsivity (SUCRA = 72.5%, SMD = -1.60, and 95% CI: -3.02 to -0.19) and inattention (SUCRA = 96.3%, SMD = -1.51, and 95% CI: -2.33 to -0.69) improvement.
CONCLUSION
Physical exercise can significantly help to alleviate the symptoms of ADHD and improve executive functions in children and adolescents with ADHD. Most of all, to promote adherence to treatment, they should be encouraged to perform the physical exercises that they enjoy most.

Meta-Analysis
Preterm birth is a major cause of neonatal morbidity and mortality worldwide. Increasing evidence links the vaginal microbiome to the risk of spontaneous preterm labour that leads to preterm birth. The aim of this systematic review and network meta-analysis was to investigate the association between the vaginal microbiome, defined as community state types (CSTs, i.e. dominance of specific lactobacilli spp, or not (low-lactobacilli)), and the risk of preterm birth. Systematic review using PubMed, Web of Science, Embase and Cochrane library was performed. Longitudinal studies using culture-independent methods categorizing the vaginal microbiome in at least three different CSTs to assess the risk of preterm birth were included. A (network) meta-analysis was conducted, presenting pooled odds ratios (OR) and 95% confidence intervals (CI); and weighted proportions and 95% CI. All 17 studies were published between 2014 and 2021 and included 38-539 pregnancies and 8-107 preterm births. Women presenting with "low-lactobacilli" vaginal microbiome were at increased risk (OR 1.69, 95% CI 1.15-2.49) for delivering preterm compared to Lactobacillus crispatus dominant women. Our network meta-analysis supports the microbiome being predictive of preterm birth, where low abundance of lactobacilli is associated with the highest risk, and L. crispatus dominance the lowest.

INTRODUCTION
BDSM is an abbreviation used to reference the concepts of bondage and discipline, dominance and submission, sadism and masochism, enacted by power exchanges between consensual partners. In recent years, attention has shifted from the idea of BDSM as a pathological and tabooed niche practice towards viewing BDSM as a healthy form of intimacy.
AIM
This systematic review brings together all existing literature on the biology of BDSM and places it in a broader biological context.
METHODS
A systematic search was conducted on PubMed, Web of Science and PsycARTICLES, of which 10 articles are included and discussed in this systematic review.
RESULTS
There is evidence for cortisol changes in submissives as a result of a BDSM interaction, suggesting involvement of the physiological stress system. Endocannabinoid changes implicate the pleasure and reward system. In dominants, this biologically measured pleasure seemed to be dependent on power play rather than pain play. Testosterone and oxytocin are also implicated in BDSM, though their role is less evident. Research into brain region activity patterns related to BDSM interest suggests a role for the parietal operculum and ventral striatum in the context of the pleasure and reward system, the primary and secondary somatosensory cortex in the context of pain perception, empathy-related circuits such as the anterior insula, anterior midcingulate cortex and sensorimotor cortex and the left frontal cortex in the context of social and sexual interactions. Pain thresholds are shown to be higher in submissive individuals and a BDSM interaction may cause pain thresholds to rise in submissives as well.
CONCLUSION
BDSM interactions are complex and influenced by several psychological, social and biological processes. Though research is limited, there is emerging evidence for an interaction between several biological systems involved in these types of interests and activities. This means there is an important role for future research to replicate and supplement current results. Wuyts E, Morrens M. The Biology of BDSM: A Systematic Review. J Sex Med 2022;19:144-157.

Review
INTRODUCTION
BDSM (bondage and discipline, dominance and submission, and sadism and masochism) increasingly receives attention from the scientific community. Where earlier research efforts mainly focused on epidemiologic characteristics, psychological and biologic factors driving BDSM preferences have recently gained interest as well.
AIM
To bring together all the existing scientific literature on BDSM from a biopsychosocial perspective.
METHODS
Based on the PRISMA guidelines, the current systematic review brings together all the existing literature on BDSM from a biopsychosocial perspective.
MAIN OUTCOME MEASURE
Prevalence rates of BDSM interests were investigated in the literature, as well as the associations between BDSM interests on one hand and personality traits, adverse childhood experiences, education levels, sexual orientations and biological markers on the other.
RESULTS
Biologic factors such as gender identity, sex hormone levels, and the neurologic constitution of the brain's pain and reward systems influence BDSM orientation. With regard to psychological factors, both personality traits (eg, higher levels of openness or extraversion) and the presence of a personality disorder have been associated with a heightened interest in BDSM, although only limited supporting evidence is available. Additionally, sensation-seeking levels and impulsivity seem to contribute, because they presumably guide one's drive to explore new or more-intense kinks. Whereas attachment styles impact couple dynamics, they also influence willingness to explore limits in a BDSM context. Lastly, education levels impact relational and sexual dynamics.
STRENGTHS AND LIMITATIONS
The limitations of the current review reflect those of the topical scientific literature. Although the number of studies focused on all aspects of BDSM is exponentially growing, most of these are only descriptive, and very few focus on underlying driving processes.
CONCLUSION
From this biopsychosocial perspective, we offer a dimensional approach while integrating the factors driving the onset and evolution of BDSM interests. De Neef N, Coppens V, Huys W, et al.

Review
OBJECTIVE
To systematically review the literature to identify risk factors for calf strain injury, and to direct future research into calf muscle injuries.
DESIGN
Systematic review DATA SOURCES: Database searches conducted for Medline, CINAHL, EMBASE, AMED, AUSPORT, SportDiscus, PEDro and Cochrane Library. Manual reference checks, ahead of press searches, citation tracking. From inception to June 2016.
ELIGIBILITY CRITERIA FOR SELECTING STUDIES
Studies evaluating and presenting data related to intrinsic or extrinsic risk factors for sustaining future calf injury.
RESULTS
Ten studies were obtained for review. Subjects across football, Australian football, rugby union, basketball and triathlon were reported on, representing 5397 athletes and 518 calf/ lower leg muscle injuries. Best evidence synthesis highlights chronological age and previous history of calf strain are the strongest risk factors for future calf muscle injury. Previous lower limb injuries (hamstring, quadriceps, adductor, knee) show some limited evidence for an association. Numerous factors lack evidence of an association, including height, weight, gender and side dominance.
SUMMARY/CONCLUSION
Increasing age and previous calf strain injury are the most predictive of future calf injury. The overall paucity of evidence and the trend for studies of a high risk of bias show that further research needs to be undertaken.

Brazilian Journal of Physical Therapy 2018Muscle strength is an important component of health.
BACKGROUND
Muscle strength is an important component of health.
OBJECTIVE
To describe and evaluate the studies which have established the reference values for muscle strength on healthy individuals and to synthesize these values with a descriptive meta-analysis approach.
METHODS
A systematic review was performed in MEDLINE, LILACS, and SciELO databases. Studies that investigated the reference values for muscle strength of two or more appendicular/axial muscle groups of health individuals were included. Methodological quality, including risk of bias was assessed by the QUADAS-2. Data extracted included: country of the study, sample size, population characteristics, equipment/method used, and muscle groups evaluated.
RESULTS
Of the 414 studies identified, 46 were included. Most of the studies had adequate methodological quality. Included studies evaluated: appendicular (80.4%) and axial (36.9%) muscles; adults (78.3%), elderly (58.7%), adolescents (43.5%), children (23.9%); isometric (91.3%) and isokinetic (17.4%) strength. Six studies (13%) with similar procedures were synthesized with meta-analysis. Generally, the coefficient of variation values that resulted from the meta-analysis ranged from 20.1% to 30% and were similar to those reported by the original studies. The meta-analysis synthesized the reference values of isometric strength of 14 muscle groups of the dominant/non-dominant sides of the upper/lower limbs of adults/elderly from developed countries, using dynamometers/myometer.
CONCLUSIONS
Most of the included studies had adequate methodological quality. The meta-analysis provided reference values for the isometric strength of 14 appendicular muscle groups of the dominant/non-dominant sides, measured with dynamometers/myometers, of men/women, of adults/elderly. These data may be used to interpret the results of the evaluations and establish appropriate treatment goals.

Review
Autosomal dominant polycystic kidney disease (ADPKD) is the most common inherited kidney disease. It has been associated with a significant physical and psychological burden, leading to a reduced quality of life. The purpose of this literature review is to summarize the patient perspective on ADPKD based on the current published literature. A systematic literature review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Publications reporting a patient or caregiver/relative perspective of ADPKD were included. Sources searched included Medline (PubMed), Embase (Ovid), Cochrane Library, and Web of Science from inception to April 2022. This was followed by a subsequent reference and citation search. A total of 1011 articles were identified by the search process, with 28 studies included in the review. An inductive thematic analysis identified six key themes: diagnosis, monitoring, and screening; symptoms; lifestyle and dietary interventions; psychological, physical, and social impact; future planning; and interaction with the health care system. The findings of this review highlight the burden and uncertainty associated with ADPKD from a patient's perspective. This impacts patients and their caregivers/relatives at each stage of the patient's journey from screening to initiation of renal replacement therapy and future planning.

Meta-Analysis Review
PURPOSE
Recurrent pregnancy loss (RPL) is affecting 1-4% of women who conceive approximately, and no cause could be found in more than 50% of women suffering from RPL. Inherited thrombophilias have got increasing attention in women with unexplained RPL, so we aim to explore the relationship among these most common thrombophilic polymorphisms and RPL through a literature review and meta-analysis.
METHODS
Observational studies from PubMed, Embase, Cochrane, and Web of Science from 1997 to 7 April 2022 were searched. For each genetic variant, a fixed or random-effect model was used according to the heterogeneity test to calculate pooled ORs and 95% CIs for both dominant and recessive genetic models. Egger's line regression test was used to assess publication bias. The quality of the included articles was assessed by the Newcastle Ottawa scale.
RESULTS
A total of 124 articles comprising 17,278 RPL patients and 16,021 controls were included. Results showed that hyperhomocysteinemia (MTHFR) C677T (dominant model: OR, 1.43; 95% CI, 1.25-1.64; recessive model: OR, 1.60; 95% CI, 1.36-1.87), MTHFR A1298C (dominant model: OR, 1.66; 95% CI, 1.26-2.18; recessive model: OR, 1.79; 95% CI, 1.42-2.26), PAI-1 4G/5G (dominant model: OR, 1.67; 95% CI, 1.36-2.06; recessive model: OR, 1.80; 95% CI, 1.39-2.32), angiotensin-converting enzyme I/D (OR, 1.23; 95% CI, 1.00-1.53), Factor XIII V34L (OR, 1.38; 95% CI, 1.02-1.87), and β-fibrinogen-455G/A (OR, 1.60; 95% CI, 1.02-2.51) were significantly associated with RPL.
CONCLUSION
This study provides potentially useful clinical markers to evaluate the risk of RPL or to help unexplained RPL patients identify possible causes, which may allow for targeted treatment.

Meta-Analysis Review
BACKGROUND
Autism spectrum disorder (ASD) is neurodevelopmental disorder characterized by stereotyped behavior and deficits in communication and social interactions. To date, numerous studies have investigated the associations between genetic variants and ASD risk. However, the results of these published studies lack a clear consensus. In the present study, we performed a systematic review on the association between genetic variants and ASD risk. Meanwhile, we conducted a meta-analysis on available data to identify the association between the single nucleotide polymorphisms (SNPs) of candidate genes and ASD risk.
METHODS
We systematically searched public databases including English and Chinese from their inception to August 1, 2022. Two independent reviewers extracted data and assessed study quality. Odds ratio and 95 % confidence interval were used as effect indexes to evaluate the association between the SNPs of candidate genes and the risk of ASD. Heterogeneity was explored through subgroup, sensitivity, and meta-regression analyses. Publication bias was assessed by using Egger's and Begg's tests for funnel plot asymmetry. In addition, TSA analysis were performed to confirm the study findings.
RESULTS
We summarized 84 SNPs of 32 candidate genes from 81 articles included in the study. Subsequently, we analyzed 16 SNPs of eight genes by calculating pooled ORs, and identified eight significant SNPs of contactin associated protein 2 (CNTNAP2), methylentetrahydrofolate reductase (MTHFR), oxytocin receptor (OXTR), and vitamin D receptor (VDR). Results showed that seven SNPs, including the CNTNAP2 rs2710102 (homozygote, heterozygote, dominant and allelic models) and rs7794745 (heterozygote and dominant models), MTHFR C677T (homozygote, heterozygote, dominant, recessive and allelic models) and A1298C (dominant and allelic models), OXTR rs2254298 (homozygote and recessive models), VDR rs731236 (homozygote, dominant, recessive and allelic models) and rs2228570 (homozygote and recessive models), were showed to be correlated with an increased ASD risk. By contrast, the VDR rs7975232 was correlated with a decreased the risk of ASD under the homozygote and allelic models.
CONCLUSION
Our study summarized research evidence on the genetic variants of ASD and provides a broad and detailed overview of ASD risk genes. The C677T and A1298C polymorphisms of MTHFR, rs2710102 and rs7794745 polymorphisms of CNTNAP2, rs2254298 polymorphism of OXTR, and rs731236 and rs2228570 polymorphisms of VDR were genetic risk factors. The rs7975232 polymorphism of VDR was a genetic protective factor for ASD. Our study provides novel clues to clinicians and healthcare decision-makers to predict ASD susceptibility.
