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
Asthma is a chronic inflammatory airway disease characterized by recurrent symptoms in response to a wide range of external stimuli, including allergens, viral infections, and air pollution together with internal host-derived danger signals. The disease is traditionally associated with adaptive immune responses; recent research emphasizes the critical role of innate immunity in its pathogenesis. The complement system, activated as part of the defense mechanisms, plays a crucial role in bridging innate to adaptive immunity. While experimental models demonstrate complement cascade activation in asthma, human studies remain limited. This systematic review summarizes existing literature on the complement system in asthma patients, gathering data from PubMed, Web of Science, Scopus, and Google Scholar. The protocol was registered in the OSF. Out of 482 initially identified articles, only 24 met the eligibility criteria, revealing disparities in sample origin, methodologies, and populations. Despite observed heterogeneity, a consistent result was found in the elevation of complement regulatory proteins, such as complement Factor H, in samples from patients with asthma compared to those from healthy subjects. The increased level of regulatory proteins, such as Factor H and I highlight that these may influence asthma pathophysiology. The role of complement factors as potential biomarkers of asthma activity and severity needs further evaluation.

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.

BACKGROUND
The global coronavirus 2019 (COVID-19) pandemic began in early 2020, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In mid-2020 the CIAO (Modelling the Pathogenesis of COVID-19 Using the Adverse Outcome Pathway Framework) project was established, bringing together over 75 interdisciplinary scientists worldwide to collaboratively investigate the underlying biological mechanisms of COVID-19 and consolidate the data using the Adverse Outcome Pathway (AOP) Framework. Neurological symptoms such as anosmia and encephalitis have been frequently reported to be associated with infection with SARS-CoV-2.
OBJECTIVE
Within CIAO, a working group was formed to conduct a systematic scoping review of COVID-19 and its related neurological symptoms to determine which key events and modulating factors are most commonly reported and to identify knowledge gaps.
DESIGN
LitCOVID was used to retrieve 86,075 papers of which 10,244 contained relevant keywords. After title and abstract screening, 2,328 remained and their full texts were reviewed based on predefined inclusion and exclusion criteria. 991 studies fulfilled the inclusion criteria and were retrieved to conduct knowledge synthesis.
RESULTS
The majority of publications reported human observational studies. Early key events were less likely to be reported compared to middle and late key events/adverse outcomes. The majority of modulating factors described related to age or sex. Less recognised COVID-19 associated AO or neurological effects of COVID-19 were also identified including multiple sclerosis/demyelination, neurodegeneration/cognitive effects and peripheral neuronal effects.
CONCLUSION
There were many methodological and reporting issues noted in the reviewed studies. In particular, publication abstracts would benefit from clearer reporting of the methods and endpoints used and the key findings, to ensure relevant papers are included when systematic reviews are conducted. The information extracted from the scoping review may be useful in understanding the mechanisms of neurological effects of COVID-19 and to further develop or support existing AOPs linking COVID-19 and its neurological key events and adverse outcomes. Further evaluation of the less recognised COVID-19 effects is needed.

Review
The current study aimed at systematically reviewing evidence on the relationships between gender minority stress and mental health outcomes among European transgender and gender diverse (TGD) individuals. A systematic search was conducted in PsycINFO, PubMED, Scopus, and Google Scholar. It was based on Boolean operators to combine terms related to minority stress, TGD identities, and mental health. Thirty studies were identified as eligible. The results confirmed that gender minority stress factors are significantly related with mental health problems among European TGD individuals. Distal stressors were identified as strongly associated with poorer mental health, with gender-related discrimination emerging as the most documented risk factor. The significant role of proximal stressors was also highlighted, with some mediation analyses detecting an indirect effect on mental health. However, identity concealment appeared unrelated to mental health outcomes. Resilience-promoting factors buffering the impact of stressors were also identified, including self-esteem, pride, transitioning, and social support. Conversely, data on community connectedness as a source of resilience were inconclusive. The studies reviewed have several limitations, including lack of longitudinal designs, sampling bias, variability in measurement methods, and unaccounted ethnic variables. Research and clinical recommendations in this field are reported.

OBJECTIVES
Although there are calls for women's empowerment and gender equity globally, there are still large disparities regarding women's autonomy in healthcare decision making. The autonomy of women is believed to be crucial in improving their health-related outcomes. This review discusses factors that influence autonomy among women in healthcare decision making.
DESIGN
Systematic review.
DATA SOURCES
PubMed, Web of Science and Scopus were searched from 2017-2022.
ELIGIBILITY CRITERIA
The inclusion criteria include original articles, case studies and reports that has been written in the English Language, while manuscripts with no full article, reviews, newspaper reports, grey literatures, and articles that did not answer the review objectives were excluded.
DATA EXTRACTION AND SYNTHESIS
We carried out data extraction using a standardized data extraction form, that has been organized using Microsoft Excel. A narrative synthesis was carried out to combine the findings of all included articles.
RESULTS
A total of 70 records were identified and 18 were reviewed, yielding eight articles to be included in the accepted list of studies. All studies were conducted in developing countries and most of the studies were cross sectional. Factors that were associated with women's autonomy in healthcare decision making were age, women's education and occupation, husbands'/partners' education and occupation, residential location or region of residence, household wealth index as well as culture and religion.
CONCLUSIONS
Identification of these factors may help stakeholders in improving women's autonomy in healthcare decision making. Policymakers play a crucial role in healthcare decision making by enacting laws and policies that protect women's rights, promoting gender-sensitive healthcare services, ensuring access to comprehensive information, promoting health education, and supporting vulnerable populations. These efforts ensure women's autonomy including able to access to unbiased and effective healthcare services.

Meta-Analysis Review
BACKGROUND
Among plastic surgeons, there are several conventional techniques for performing chest surgery. Research on surgical approaches has focused cis-gender patients with medical conditions, such as breast cancer or gynecomastia, but has never studied transgender populations. The aim of this study is to perform the first systematic review of gender-affirming surgery (GAS) in transgender populations and determine postoperative outcomes differences in relation to surgical technique.
METHODS
Two reviewers independently searched Medline, Embase, CINAHL, Web of Science, and Cochrane databases for studies published prior to 2021. Studies selected for inclusion were retrospective or prospective studies of adult transgender men undergoing GAS that utilized appropriate operative techniques and reported complications and/or patient-reported outcomes.
RESULTS
A total of 26 randomized controlled trials, including 40 distinct populations and 3055 patients, were identified. Surgical techniques compared double incision free nipple graft (DIFNG) (2053 patients [67.20%]), pedicled nipple techniques (PNT) (297 [9.72%]), and periareolar techniques (PAT) (705 [23.08%]). Pairwise analysis found the lowest complication rates associated with procedures utilizing DIFNG, followed by PNT, then PAT. Patients with PAT had significantly higher satisfaction scores than DIFNG.
CONCLUSIONS
This is the first systematic review to evaluate outcomes of chest surgery techniques among the transgender population. Results indicate significantly more complications for PAT compared to DIFNG or PNT. Analysis of patient-reported outcomes was limited due to heterogeneity in reporting.

Sexual and gender minorities (SGM) constitute vulnerable groups in many countries. Thus, they might be affected to a different extent than heterosexual and cisgender individuals by the Coronavirus pandemic. This systematic review aimed to summarize the state of international research on the mental and physical health-related as well as socioeconomic effects of the Coronavirus pandemic on SGM individuals. Following the PRISMA protocol, we identified 35 publications, including different article formats. We considered minority stress theory and intersectionality in synthesizing the reviewed literature. Our key finding implicates that both minority- and pandemic-specific adversities have increased the vulnerabilities of SGM individuals during the Coronavirus pandemic. Minority-specific stressors include discrimination experiences, poorer mental and physical health, and fewer socioeconomic resources. Pandemic-specific challenges such as the deferral and delay of medication or school closing have exposed certain SGM subgroups (transgender individuals, young SGM) to particularly high risk. Moreover, the reviewed evidence suggests distinctive interactive effects of minority-specific stressors with pandemic-specific challenges (e.g., being forced to stay close to rejecting others during lockdown periods). A significant share of the included literature was US-based, while research from other countries remained scarce. The specific mechanisms still deserve to be better understood to protect SGM in future crises, especially during pandemics.

Review
Various viruses cause viral infection, and these viruses have different microscopic sizes, genetic material, and morphological forms. Due to a viral infection, the host body induces defense mechanisms that activate the innate and adaptive immune system. sncRNAs are involved in various biological processes and play an essential role in antiviral response in viruses including ZIKV, HCV, DENV, SARS-CoV, and West Nile virus, and regulate the complex interactions between the viruses and host cells. This review discusses the role of miRNAs, siRNAs, piRNAs, and tiRNAs in antiviral response. Cellular miRNAs bind with virus mRNA and perform their antiviral response in multiple viruses. However, the chemical modifications of miRNA necessary to avoid nuclease attack, which is then involved with intracellular processing, have proven challenging for therapeutic replacement of miRNAs. siRNAs have significant antiviral responses by targeting any gene of interest along the correct nucleotide of targeting mRNA. Due to this ability, siRNAs have valuable characteristics in antiviral response for therapeutic purposes. Additionally, the researchers noted the involvement of piRNAs and tiRNAs in the antiviral response, yet their findings were deemed insignificant.

Meta-Analysis
BACKGROUND
Malaria, a severe health threat, significantly affects total antioxidant status (TAS) levels, leading to considerable oxidative stress. This systematic review and meta-analysis aimed to delineate differences in TAS levels between malaria patients and healthy controls, and assess correlations between disease severity and parasite density.
METHODS
The systematic review was registered with the International Prospective Register of Systematic Reviews (PROSPERO) under registration number CRD42023448761. A comprehensive literature search was conducted in databases such as Embase, MEDLINE, Journals@Ovid, PubMed, Scopus, ProQuest, and Google Scholar to identify studies reporting data on TAS levels in malaria patients. Data from the included studies were analysed both qualitatively and quantitatively. Differences in TAS levels between malaria patients and controls were pooled using a random effects model, with Hedges' g as the effect size measure.
RESULTS
Of 1796 identified records, 20 studies met the inclusion criteria. The qualitative synthesis of these studies revealed a marked decrease in TAS levels in patients with malaria compared to non-malaria cases. The meta-analysis results showed a significant decrease in TAS levels in patients with malaria compared to non-malaria cases (P < 0.01, Hedges' g: - 2.75, 95% CI - 3.72 to -1.78, I: 98.16%, 13 studies), suggesting elevated oxidative stress in these patients. Subgroup analyses revealed that TAS level variations were significantly influenced by geographical region, age group, Plasmodium species, and method for measuring TAS. Notably, TAS levels were significantly lower in severe malaria cases and those with high parasite density, indicating a potential relationship between oxidative stress and disease severity.
CONCLUSION
This study highlights the potential utility of TAS as a biomarker for disease risk and severity in malaria. The significant decrease in TAS levels in malaria patients compared to controls implies increased oxidative stress. Further well-designed, large-scale studies are warranted to validate these findings and elucidate the intricate mechanisms linking TAS and malaria.
