Introduction: Prostate cancer is one of the most common neoplasia in men, and its clinical evolution is highly influenced by psycho-emotional factors, especially in elderly patients. Comorbidities, the perception of one’s identity and its impact on life quality become relevant variables in the therapeutic decision. Sexual dysfunction after treatment along with decreased libido, erectile dysfunction and ejaculatory dysfunction are significant problems in patients with prostate cancer. Case presentation: The present study presents the oncological evolution of an elderly patient with a dual diagnosis, prostate adenocarcinoma and lung squamous cell carcinoma, who faced a significant amount of medical and psychological challenges. Reluctance to hormone therapy was closely linked to the fear of sexual dysfunction, a very common reaction in elderly men concerned with maintaining autonomy and intimacy. The peculiarity of the case consists in the interaction between the evolution of the disease, the therapeutic decisions and the psychological impact on the patient. Discussion: Androgen deprivation therapy negatively influences multiple aspects of sexual function, significantly impairing the life quality of patients diagnosed with prostate cancer. In this context, therapy through acceptance and commitment is the appropriate one, its main purpose being to change the patient’s relationship with suffering—from struggle and rejection to active acceptance and value of the present. The intervention of the psychologist or the psychotherapist is essential in decision-making counseling, using coping techniques, the clarification of personal values and the involvement of the family in the decision-making process. Oncological psychology helps the patient redefine their life goals and priorities, not just to choose a treatment. Conclusions: Sexuality and psychological health are deeply affected by prostate cancer. Psychological flexibility and emotional support can mitigate this negative impact. The integration of therapy through acceptance and commitment in the rehabilitation after treatment increases effectiveness and patient satisfaction. Full article

Background: Chemsex, the intentional use of psychoactive substances to enhance sexual experiences, is an emerging public health issue in Brazil, associated with increased risks of sexually transmitted infections and complex psychosocial vulnerabilities. Despite the universal coverage provided by the Unified Health System (SUS), individuals who practice chemsex often encounter barriers to healthcare, including stigma, discrimination, and a lack of specialized services. To date, no comprehensive reviews appear to synthesize evidence on how this population accesses healthcare in the Brazilian context; existing knowledge remains fragmented across individual studies. Objectives: The aim is to map and synthesize the available evidence regarding access to health services among people who engage in chemsex in Brazil, identifying health needs, professional demands, barriers, and facilitators. Methods: The protocol follows the Joanna Briggs Institute methodology for scoping reviews and PRISMA-ScR guidelines. A systematic search will be conducted in MEDLINE (PubMed), Embase, Scopus, SciELO, and LILACS for studies published between 2014 and 2024 in Portuguese, English, or Spanish. Data will be summarized using descriptive and narrative synthesis, presented in tables and thematic categories. Studies will be included if they address chemsex or sexualized drug use in Brazil and report on healthcare access, regardless of gender identity, sexual orientation, or drug type. Studies that do not address chemsex, focus on drug use outside a sexual context, or are unrelated to Brazil will be excluded. Expected results: The review is expected to identify key barriers and facilitators to healthcare access, highlight knowledge gaps for underrepresented groups, and support recommendations for research, policy, and practice to improve care for people engaging in chemsex in Brazil. By focusing on an underexplored intersection of drug use, sexuality, and healthcare access in Latin America, this study aims to provide an innovative contribution to public health literature.

Background: Research exploring the context in which ASD and offending are associated is limited, despite stereotyped perceptions that individuals with ASD are more violent than their typically developing peers. To address this gap, this research explored the influence of ASD, mental health and behavioural presentation, adverse childhood experiences, and demographic characteristics on offending presentations in a forensic youth sample. Methods: This was a cross-sectional study of a retrospective cohort, utilising secondary data of 327 young people from a forensic London-based service (83% male, M_age = 14.9 years old, SD = 1.90). Results: One hundred forty-two of these young people presented with either confirmed or suspected ASD diagnoses (83.8% male, M_age = 14.8 years old, SD = 1.84). Five offending categories (violence, sexually harmful behaviour, drug possession/supply, gang involvement, theft) and 32 offending behaviours were analysed in total. Poisson and negative binomial regression analyses indicated that ASD traits only increased the rate ratio of violent offences (p = 0.036) and gang involvement (p = 0.002). The use of substances significantly increased the rate ratio of theft (p = 0.012), gang involvement (p = 0.004), and drug possession/supply (p = 0.012). Conclusions: Our findings suggest that ASD, in the context of substance use, may increase a young person’s risk for more variable violent offences or gang involvement. Findings are discussed in the context of current research and recommendations for clinical practice and future research are made. Full article

Background/Objectives: Gender (roles as household load and job strain, and identity) represent an effect modifier of the interference between pain experience and sex because it is different between men and women. This study validates a new scale developed to assess how life functioning is impacted by Chronic Non-Cancer Pain (CNCP) due to gender. Methods: A total of 193 Spanish ambulatory CNCP patients (60 [51–73] years old, 69.4% women, 31% retired) were interviewed. Exploratory Factor Analysis (EFA) yielded 3-factor structure: Gender Self-identity, Roles, and Chronic Pain Impact on Social, Familial, Work and Sexual Life. Results: The Gender-Pain Questionnaire, with the presented factor structure, is an evaluation instrument with enough reliability and internal validity for CNCP patients. Conclusions: This study presents the psychometric properties of a scale for assessing the interference of CNCP patients’ experience on gender and how it affects their daily life activities, relationships and self-identity. It represents the first original questionnaire known in Spanish language to date. This measure could potentially help researchers and clinicians to obtain gender key information to design appropriate and equity healthcare interventions. Full article

Among terrestrial animals, spiders exhibit the most striking examples of sexual size dimorphism (SSD) but better understanding of its evolution requires improved taxonomy and phylogeny. Many sexually dimorphic spiders lack adequate description, phylogenetic placement, and natural history observations. In South Africa, we documented the natural history of a poorly known spider, Megaraneus gabonensis (Lucas, 1858), with extreme, female-biased SSD (eSSD, female:male approximately 4:1). Here, we redescribe M. gabonensis, place Megaraneus Lawrence, 1968 phylogenetically for the first time, assess whether the observed eSSD represents an independent evolutionary origin, and test whether the macroevolutionary pattern is better explained by male dwarfism or female gigantism. The recovered phylogenetic placement of Megaraneus in the araneid ‘backobourkiines’, a clade previously considered as restricted to East Asia and Australasia, extends the range of this clade to the Afrotropics. We find that eSSD was present in the common ancestor of the ‘backobourkiines’, with further increases in female body length occurring independently in Megaraneus, Backobourkia Framenau, Dupérré, Blackledge & Vink, 2010, and the currently misplaced Parawixia dehaani (Doleschall, 1859). We conclude that the evolution of eSSD reflects a complex pattern of sex-specific size changes across spider phylogeny, but that in Megaraneus it results from female gigantism. Full article

Heterotopic ossification (HO) is a disease characterized by ectopic bone formation, which can occur following severe traumatic brain injury (TBI). However, the underlying mechanisms remain poorly understood. In this study, we established a stem cell model using adipose-derived stem cells (ADSCs) and skeletal stem cells (SSCs) to examine osteogenic factors present in the sera of TBI patients. Incubation of ADSCs and SSCs with osteoinductive medium supplemented with TBI serum significantly enhanced osteogenic differentiation, particularly in male ADSCs and both female and male SSCs, with male SSCs exhibiting the highest osteogenic potential. Furthermore, we identified TGF-β1 as an important factor involved in these osteogenic processes. Elevated levels of TGF-β1 were detected in the serum of male TBI patients 14 days post-injury. Cellular assays revealed a sexual dimorphism in response to TGF-β1 neutralization: osteogenic differentiation in male SSCs was significantly reduced, while no effect was detectable in female SSCs. These findings, together with the rarity of HO in female patients, suggest that TGF-β1 plays a central role in the development of HO in males. Furthermore, this study highlights the importance of considering sex-specific mechanisms in traumatic HO for the development of sex-specific therapy options. Full article

This paper offers a critical analysis of traditional Muslim sexual morality and questions its validity in the present. It focuses on two elements: (1) nikāḥ as a legal marriage contract characterized by asymmetrical gender roles and (2) historically permitted sexual relations with enslaved women, as well as Muslim positions on sexual intercourse with minors. After a conceptual clarification of sexual autonomy, I examine the positions of different legal schools and contextualize their norms within broader social and intellectual histories. Building on the approach of “overcoming the text,” I argue that foundational religious texts can no longer serve as the normative basis for a contemporary sexual ethic. Instead, I redefine the notion of “illegitimate sexuality” (zinā) based on the principle of sexual autonomy and show how modern legal and social frameworks (rule of law, welfare state, medical evidence) render earlier functions of sexual regulation obsolete. The Qurʾanic concept of maʿrūf serves as a dynamic ethical reference point. The goal is a paradigm shift toward a Muslim sexual ethic that centers autonomy, equality, and human dignity while critically dismantling inherited structures. Full article

Cooperative breeding, or helping behavior, has long been recognized in birds. An ignored dichotomy, however, separates the helping found in many individuals of some long-lived, sedentary species from the helping occasionally found in the territories of isolated breeding pairs of some short-lived, long-distance migrant species. Both types of helping are called “cooperative breeding” in the literature. However, recognizing a dichotomy of “frequent” versus “infrequent” cooperative breeding would help justify the study of infrequent helping as a distinct discipline. Cooperative breeding in Wilson’s Warblers is infrequent, and among the unique behaviors found during this study were (1) solicitations by helper males, which aborted host male attacks and apparently initiated territorial acceptance, (2) an absence of sexual aggression between helper males and fertile host females, (3) attacks by helper males on intruding males during host female nest building, (4) helper males singing with impunity when host males were absent from territories, but being attacked when host males were present, and (5) a single male simultaneously serving as a helper in four adjacent host territories. Infrequent helping has essentially been ignored in studies and summaries of cooperative breeding. However, recognizing and studying infrequent helping as a distinct behavioral process could reveal interactions between helping and population ecology. Thus, infrequent cooperative breeding detected in a breeding population could reveal territorial saturation and could indicate that the population is likely ecologically healthy. Full article

Background: Bahiagrass (Paspalum notatum), a key cultivated grass worldwide, includes both sexual diploid and apomictic tetraploid cytotypes. Finding new diploid populations is crucial for the species’ genetic improvement and conservation. Objectives: We aimed to determine the ploidy levels of 168 P. notatum accessions from subtropical South America, analyze the geographic distribution of cytotype diversity, and identify new diploid zones. Methods: Using chromosome counts and flow cytometry, we georeferenced our data with existing literature to map cytotype distribution. Results: We discovered five previously unknown diploid centers in Argentina, Brazil, and Paraguay, two of which resulted from the naturalization of diploid cultivars. One location hosted a mixed-ploidy population (diploid, tetraploid, and pentaploid), confirming ongoing hybridization. Our results show that human activity actively creates new centers of genetic diversity, serving as a dynamic source of raw material for crop resilience. These neonative diversification zones are not only of scientific interest but also vital, evolving hotspots for germplasm conservation. Conclusions: This study presents a new framework for understanding the interactions between crop and wild relatives and highlights the urgent need for conservation in the rapidly changing South American grasslands.

Suicide is a significant public health concern associated with multiple risk factors. Among these factors, a history of trauma and impulsivity has recently received particular attention. Nevertheless, the relationship between trauma, impulsivity, and functional impairment in individuals who attempt suicide remains to be fully elucidated. This study aimed to examine the association between trauma, impulsivity, and functioning in a clinical sample with previous suicide attempts. A total of 293 patients were included in the study, with a mean age of 41.42 years (SD 14.37 years). The participants had consulted hospitals due to suicide attempts or severe suicidal ideation. The patients were recruited from three hospitals across Spain. Participants completed assessments designed to measure childhood trauma, impulsivity, and functioning. Pearson’s correlations and logistic regression analyses were used to explore associations between trauma, impulsivity, and their impact on functioning. The findings of the present study indicated a modest yet statistically significant correlation between trauma and impulsivity and between impulsivity and functioning. The findings of the logistic regression analysis indicated that physical and sexual abuse, in conjunction with impulsivity, were significant predictors of diminished functioning. The present study found no evidence of a moderating effect of gender or age in the observed relationships. After controlling for all significant variables, impulsivity was the only factor that retained its statistical significance. The present findings underscore the significance of incorporating a focus on impulsivity within clinical interventions targeting individuals who have attempted suicide, with the objective of enhancing their overall functionality.

Cardiovascular diseases (CVDs) remain the leading cause of morbidity and mortality worldwide. Increasing evidence indicates that sex differences significantly influence the development, progression, and outcomes of CVDs. Recent advances have highlighted the central role of mitochondria, not only as cellular energy hubs but also as key regulators of oxidative stress, inflammation, and apoptosis, in mediating sex-specific cardiovascular responses. This review explores sexual dimorphism in cardiovascular disease, focusing on the interplay between mitochondrial function and sex hormones in cardiovascular tissues. We summarize current evidence on the molecular, hormonal, and cellular mechanisms contributing to sex-based disparities in cardiovascular outcomes. Preclinical studies suggest that female cardiac mitochondria may exhibit greater antioxidant capacity and produce fewer reactive oxygen species than male mitochondria, contributing to enhanced cardioprotection. Estrogen has been shown to influence mitochondrial bioenergetics and gene expression, affecting vascular tone, inflammation, and cardiac remodelling, whereas the role of testosterone remains less well defined. Additionally, sex-specific mitochondrial signalling responses have been reported under cardiac stress conditions, which may underlie differences in disease presentation and progression. A better understanding of how sex modulates mitochondrial function could improve risk stratification and support the development of personalized prevention and treatment strategies. Further research is needed to translate these mechanistic insights into clinical practice. Full article

Microtus ochrogaster, monogamous prairie voles, serve as translational animal models for studying monogamy and pair bonding. Microglia, the resident immune cells of the brain, are one of several cell types still poorly understood in non-classical animal models including prairie voles. Microglia are known to play mechanistic roles in mediating social behaviors using inflammatory signaling, but the relationship between microglia reactivity and pair bonding has not yet been investigated. The present study first developed a robust protocol for quantitative histological visualization of microglia in Microtus ochrogaster. Second, it investigated differences in microglia morphology, a reliable index of microglia reactivity and function, in pair-bonded vs. unpaired voles. Sections containing prefrontal cortex (PFC) and anterior cingulate cortex (ACC) were stained for ionized calcium-binding adaptor molecule I (Iba1) using immunohistochemistry (IHC). IHC results provided evidence for the successful use of murine histological protocols in prairie voles. Quantification results revealed a sexually dimorphic effect of pair bonding on microglia: somas were significantly larger in pair-bonded vs. unpaired females, and somas were significantly smaller in pair-bonded vs. unpaired males. Additionally, somas were significantly larger in unpaired males than females, with larger somas indicating higher microglia reactivity. While conclusions are limited due to the small sample size, results provide novel characterization of microglia morphology in the frontal cortex and elucidate how pair bonding may influence microglia function in a sexually dimorphic manner.

Society has long held negative beliefs and attitudes, in the form of sexual stigma, towards sexual minorities (e.g., lesbian, gay, and bisexual; LGB). Sexual stigma can be adopted and internalized by LGB individuals as their own beliefs and attitudes. In LGB individuals, internalized sexual stigma can result in psychological distress such as low self-esteem, depression, shame, and feelings of rejection. However, an instrument to assess internalized sexual stigma specifically developed for LGB individuals is lacking. The present study focuses on the development of a new instrument, the Perceived Internalized Sexual Stigma Measure (PrISSM), that is inclusive of LGB individuals who are 18 years and older. Exploratory and Bayesian confirmatory factor analyses indicate that internalized sexual stigma, as measured by the PrISSM, consists of two factors: internal conflict and disclosure conflict. The two-factor structure is also invariant to LGB individuals. As such, items of the PrISSM do not need to be separately reworded for lesbian, gay, or bisexual individuals. In addition, the PrISSM is a brief instrument composed of 4 items per factor (8 items total). Convergent and discriminant validity evidence is also provided. Full article

Involuntary urinary leakage due to stress urinary incontinence in women represents a widespread health condition that reduces quality of life. Background: Treatment with tension-free vaginal tape (TVT) remains the most used procedure, although its impact on quality of life, specifically regarding sexual function effects, has not been thoroughly investigated. The aim of our study is to achieve a broader understanding of the full range of outcomes after surgery, emotional well-being, and sexual function. Materials and Methods: The present prospective cohort study was conducted between 15 July 2023 and 15 June 2024 in the Emergency County Clinical Hospital Targu Mures, Department of Obstetrics and Gynecology. This is an investigation of TVT surgery and its impact on urinary incontinence, conducted by evaluating bladder dysfunction and sexual function before and after surgical intervention, as well as considering physical and psychological outcomes using specific questionnaires. Results: There was a 91.7% objective cure rate for incontinence, while urinary symptoms, sexual function, and emotional health significantly improved, urine leakage associated with strong urgency (p = 0.0002), urine leakage associated with coughing, sneezing, or laughing (p ≤ 0.0001), and patient sexual activity and emotional health also improved after surgery (p ≤ 0.0001). Furthermore, colorectal symptoms improved. Conclusions: This study emphasizes that for the best recovery of sexual and emotional health post-surgery, complete symptom removal is a requirement. Additionally, the significance of combined questionnaires in assessing treatment efficacy is highlighted. A larger sample size of patients and a longer follow-up are required before recommending this procedure as a standard treatment. Full article

Striatum can be described as a brain region containing a general neuronal mechanism to associate actions or events with reward. In particular, neural activity in the human striatum is modulated by social actions and, critically, by the conjunction of social actions and own reward. To perform this function, dopamine and oxytocin signaling reaching the striatum represent a key factor. These neurotransmitters, in both humans and animals, are released in response to afferent vagal and sensory stimulation, as well as sexual and social interactions, conveying information related to reward and pleasure associated with an event. Dopamine and oxytocin have several effects in common, but of particular interest is evidence indicating that they can mutually modulate their action. The present review focuses on available data delineating interactions between dopaminergic and oxytocinergic signaling in the striatum. In this context, recent data on the possible role played by striatal astrocytes and microglia as key modulators of this crosstalk will be briefly discussed. Full article
