Review
Atherosclerosis is a complex process involving endothelial dysfunction, vascular inflammation, vascular smooth muscle cell (VSMC) proliferation, angiogenesis, and calcification. One of the pathomechanisms of atherosclerosis is the upregulation of Wnt signaling. This study aimed to summarize the current knowledge regarding the role of Wnt signaling and sclerostin in atherosclerosis, vascular calcification, aneurysms, and mortality based on the PubMed database. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendation and identified 160 papers that were included in this systematic review. The published data highlight that the upregulation of Wnt components facilitates the initiation and progression of atherosclerosis, arterial remodeling, VSMCs proliferation and phenotypic transition to the osteoblastic lineage in the arterial wall. This results in protein secretion, cell migration, calcification, fibrosis and aneurysm formation. The transformation of VSMCs into osteoblast-like cells that is observed in atherosclerosis results in sclerostin expression inhibiting the Wnt pathway. Furthermore, it was shown that sclerostin, expressed in atherosclerotic plaques, inhibits aneurysm formation in a mouse model. However, in humans, while the antisclerostin antibody romosozumab inhibits bone resorption, biochemical parameters of endothelial activation and inflammation are not affected, and the incidence of aneurysms is not increased. It was suggested that detecting sclerostin in the calcified aortic atherosclerotic plaques reflects a defense mechanism against Wnt activation and inhibition of atherosclerosis, although this has only been shown in animal models. Moreover, an increased number of vascular cells converted to osteogenic phenotypes results in increased plasma sclerostin concentrations. Therefore, plasma sclerostin derived from bone limits its importance as a global marker of vascular calcification.

Gender-transformative health interventions that involve men and boys are gaining global reach, adaptability to specific geographical, population and epidemiological contexts, public endorsement, and conceptual sophistication. However, the ways in which masculinities are conceptualised and operationalised in theory and practice across these interventions remains unclear. The purpose of this scoping review is to map intervention studies that conceptually grapple with masculinities and analyse: a) how the concept of masculinities is adapted and operationalised in gender-transformative interventions, with respect to intervention population and context, b) what the relationship between the concept of masculinities and its wider theoretical embedding is, and c) on which levels transformation can be observed when working with 'masculinities'.We conducted a search in APA Psych Articles, APA PsycINFO, and CINAHL via EBSCO, MedLine, PubMed, and Web of Sciences (December 2021) looking for peer-reviewed studies on gender-transformative health interventions which engaged with masculinities conceptually. There were no restrictions regarding language, publication date, or geography. Forty-two articles were included in this review. Our abductive analysis finds that 'hegemonic masculinities' is a central concept in almost all included studies. This shows how the concept is adaptable to a range of different intervention contexts. The review further identifies five theoretical approaches, that help operationalise masculinities on an analytical level: feminist framework, affect theory, critical pedagogy, theories of social change, and ecological approaches. Lastly, this review draws out six levels on which transformation can be observed in the intervention outcomes: relational level, symbolic level, material level, affective level, cognitive-behavioural level, and community-structural level. The discussion underlines that processes and practices of (gender) transformation also require engagement with theories of transformation more widely and advocates for theoretical pluralism. Lastly, implications for practice, including preventative, ecological and community-based care models, are drawn out.

INTRODUCTION
The Family of pathogenesis-related proteins 10 (PR-10) is widely distributed in the plant kingdom. PR-10 are multifunctional proteins, constitutively expressed in all plant tissues, playing a role in growth and development or being induced in stress situations. Several studies have investigated the preponderant role of PR-10 in plant defense against biotic stresses; however, little is known about the mechanisms of action of these proteins. This is the first systematic review conducted to gather information on the subject and to reveal the possible mechanisms of action that PR-10 perform.
METHODS
Therefore, three databases were used for the article search: PubMed, Web of Science, and Scopus. To avoid bias, a protocol with inclusion and exclusion criteria was prepared. In total, 216 articles related to the proposed objective of this study were selected.
RESULTS
The participation of PR-10 was revealed in the plant's defense against several stressor agents such as viruses, bacteria, fungi, oomycetes, nematodes and insects, and studies involving fungi and bacteria were predominant in the selected articles. Studies with combined techniques showed a compilation of relevant information about PR-10 in biotic stress that collaborate with the understanding of the mechanisms of action of these molecules. The up-regulation of PR-10 was predominant under different conditions of biotic stress, in addition to being more expressive in resistant varieties both at the transcriptional and translational level.
DISCUSSION
Biological models that have been proposed reveal an intrinsic network of molecular interactions involving the modes of action of PR-10. These include hormonal pathways, transcription factors, physical interactions with effector proteins or pattern recognition receptors and other molecules involved with the plant's defense system.
CONCLUSION
The molecular networks involving PR-10 reveal how the plant's defense response is mediated, either to trigger susceptibility or, based on data systematized in this review, more frequently, to have plant resistance to the disease.

Review
PURPOSE OF REVIEW
Sexual and gender minority (SGM) individuals are diagnosed with HIV at disproportionate rates, and hazardous alcohol use can increase their HIV risk. This review assessed the state of the literature examining interventions for addressing alcohol use and sexual HIV risk behaviors among SGM individuals.
RECENT FINDINGS
Fourteen manuscripts from 2012 to 2022 tested interventions that address both alcohol use and HIV risk behaviors among SGM populations, with only 7 randomized controlled trials (RCTs). Virtually all the interventions targeted men who have sex with men, with none focused on transgender populations or cisgender women. While they demonstrated some evidence of effectiveness in reducing alcohol use and/or sexual risk, the outcomes varied widely between studies. More research is needed that tests interventions in this area, particularly for transgender individuals. The use of larger-scale RCTs with diverse populations and standardized outcome measures are needed to strengthen the evidence base.

Meta-Analysis Review
Mixed findings exist regarding whether athletes have different levels of body image concerns to non-athletes. Such body image concerns have not been reviewed recently, meaning that new findings need to be incorporated into our understanding of the adult sporting population. This systematic review and meta-analysis aimed first to characterise body image in adult athletes versus non-athletes, and second to explore whether specific sub-groups of athletes report different body image concerns. Impact of gender and competition level were considered. A systematic search identified 21 relevant papers, mostly rated moderate quality. Following a narrative review, a meta-analysis was conducted to quantify the outcomes. While the narrative synthesis indicated possible differences between types of sport, the meta-analysis demonstrated that athletes in general reported lower body image concerns than non-athletes. In general, athletes had a better body image than non-athletes, with no reliable differences between different type of sport. A combination of prevention and intervention strategies might assist athletes in focusing on the benefits to their body image without encouraging restriction/compensation or overeating. Future research should define comparison groups clearly, along with attending to training background/intensity, external pressures, gender and gender identity.

Review
Although exclusion of racially and ethnically minoritized autistic individuals from research is a long-standing issue, we have yet to determine how exclusion impacts areas of autism research important for identifying language impairment. Diagnosis depends on the quality of the evidence (i.e. research) and is often the pathway to gaining access to services. As a first step, we examined how research studies related to language impairment in school-age autistic individuals report participant socio-demographics. We analyzed reports using age-referenced assessments in English ( = 60), which are commonly used by both practitioners and researchers to diagnose or identify language impairment. Findings showed only 28% of studies reported information on race and ethnicity; in these studies, most (at least 77%) of the participants were white. In addition, only 56% of studies reported gender or sex specified what they were reporting (gender, sex, or gender identity). Just 17% reported socio-economic status using multiple indicators. Altogether, findings indicate broad issues with underreporting and exclusion of racially and ethnically minoritized individuals, which might overlay with other aspects of identity including socio-economic status. It is impossible to determine the extent and precise nature of exclusion without intersectional reporting. To ensure that language in autism research is representative of the autistic population, future research must implement reporting guidelines and broaden inclusion of who participates in research studies.

Review
A Systematic Review on Participant Diversity in Clinical Trials-Have We Made Progress for the Management of Obesity and Its Metabolic Sequelae in Diet, Drug, and Surgical Trials.
OBJECTIVE
Individuals from Black and Hispanic backgrounds represent a minority of the overall US population, yet are the populations most affected by the disease of obesity and its comorbid conditions. Black and Hispanic individuals remain underrepresented among participants in obesity clinical trials, despite the mandate by the National Institutes of Health (NIH) Revitalization Act of 1993. This systematic review evaluates the racial, ethnic, and gender diversity of clinical trials focused on obesity at a national level.
METHODS
Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic review of clinicaltrials.gov, PubMed, Cochrane Central, and Web of Science was undertaken to locate phase 3 and phase 4 clinical trials on the topic of obesity that met associated inclusion/exclusion criteria. Ultimately, 18 studies were included for review.
RESULTS
White non-Hispanic individuals represented the majority of clinical trial participants, as did females. No study classified participants by gender identity. Reporting of race/ethnicity was not uniform, with noted variability among racial/ethnic subgroups.
CONCLUSIONS
Our findings suggest that disparities remain in the diverse racial, ethnic, and gender representation of participants engaged in clinical trials on obesity relative to the prevalence of obesity in underrepresented populations. Commitment to inclusive and intentional recruiting practices is needed to increase the representation of underrepresented groups, thus increasing the generalizability of future research.
