Women are biologically more susceptible to the Human Immunodeficiency Virus (HIV) and other sexually transmitted Infections (STIs) because receptive sex is riskier than insertive. Despite condom use being the staple preventive method for HIV infection (over 80% efficacy), in Sub-Saharan African countries like Burkina Faso, a high burden of HIV and the unmet need for condom use coexist. Moreover, even though women in SSA are disproportionately HIV positive, they are reportedly less capable of negotiating condom use for HIV risk reduction...

The impressive †Oncorhynchus rastrosus of the Pacific Northwest's Miocene and Pliocene eras was the largest salmonid ever to live. It sported a hypertrophied premaxilla with a pair of enlarged teeth which the original describers reconstructed as projecting ventrally into the mouth, leading them to assign the species to "Smilodonichthys," a genus now in synonymy. Through CT reconstruction of the holotype and newly collected specimens, we demonstrate that the famed teeth projected laterally like tusks, not ventrally like sabers or fangs...

During the 1890s, animal development became associated with glandular activity, with profound implications for pediatric nosology and treatment. The significance of this endocrinological turn of developmental physiology and pathophysiology in part hinges on an often-overlooked continuity with ubiquitous early modern medical thought concerning semen as a recrementitious (reabsorbed) nutrient or stimulant. Mid-19th-century interests in adult sexual physiology were increasingly nerve-centered and antihumoral. Scattered empirical, particularly veterinarian, interests in gonadal developmental functions failed to moderate these explanatory trends...

The thymus is the site of T lymphocyte development and T cell education to recognize foreign, but not self, Ags. B cells also reside and develop in the thymus, although their functions are less clear. During "thymic involution," a process of lymphoid atrophy and adipose replacement linked to sexual maturation, thymocytes decline. However, thymic B cells decrease far less than T cells, such that B cells comprise ∼1% of human neonatal thymocytes but up to ∼10% in adults. All jawed vertebrates possess a thymus, and we and others have shown zebrafish (Danio rerio) also have thymic B cells...

This article analyzes how couples made up of two mothers redefine their roles when they break up as well as how legal professionals frame the custodial arrangements of these former same-sex couples. To do so, we focus on the case of Quebec, Canada, where parentage equality between mothers was attained as early as in 2002. We rely on individual semi-structured interviews with mothers' ( N  = 17) and legal professionals' accounts ( N  = 23) as well as on court records regarding physical custody arrangements...

Freud's very brief 1922 paper on the beheading of Medusa by Perseus wisely concludes with a call for a further examination of the sources of the legend. A now widespread interpretation of this legend is based (often without acknowledgement) on an addition to traditions concerning Medusa made in Ovid's Metamorphoses . It is argued here that this Ovidian innovation has often been misinterpreted, and that a more careful reading of Metamorphoses supports neither a widely alleged exclusively vengeful portrayal of Medusa, nor Freud's portrayal of Medusa's decapitation as solely a pitiable and terrible symbol of castration...

PURPOSE: The pathways by which adverse childhood experiences (ACEs) are associated with early marriage and early pregnancy are poorly understood. Early marriage and early pregnancy may be risk factors for adulthood intimate partner violence (IPV). The aim of this study was to assess the relationships among ACEs, early marriage, early pregnancy, and IPV among women in Honduras. METHOD: We used weighted data from 1,436 women aged 18-24 years from the nationally representative 2017 Honduras Violence Against Children and Youth Survey...

BACKGROUND: Trichomoniasis is one of the most common sexually transmitted infections worldwide. The growing concern of drug resistance of this infection has cautioned the need for new drug development. We evaluated the potential antiproliferative and apoptotic effect of α-pinene and tannic acid (TA) on Trichomonas vaginalis cells. In addition, the cytotoxicity of agents on Vero cells was investigated. METHODS: Trichomonas cells were axenically cultured in TYI-S-33 medium...

While mixed methods research can enhance studies of intervention outcomes and projects where research itself transforms communities through participatory approaches, methodologists need explicit examples. As the field of interpersonal violence prevention increasingly embraces community-level prevention strategies, it may benefit from research methods that mirror community-building prevention processes. A multiphase mixed methods study with sequential and convergent components assessed the feasibility, and impact of a prevention program to change social norms and increase collective efficacy in towns...

OBJECTIVE: We report the prevalence, characteristics and clinical outcomes of women with sexually transmitted infections (STIs) in pregnancy in the Western Sydney Local Health District (WSLHD) serving a large culturally and socio-economically diverse community in New South Wales (NSW), Australia, over the last 10 years. METHODS: A retrospective cohort study of all pregnant women booked for antenatal care at three hospitals in WSLHD between September 2012 and August 2022 inclusive...

Mpox is a zoonotic disease historically reported in Africa. Since 2003, limited outbreaks have occurred outside Africa. In 2022, the global spread of cases with sustained interhuman transmission and unusual disease features raised public health concerns. We explore the mpox outbreak in Rio de Janeiro (RJ) state, Brazil, in an observational study of mpox-suspected cases from June to December 2022. Data collection relied on a public healthcare notification form. Diagnosis was determined by MPXV-PCR. In 46 confirmed cases, anti-OPXV IgG was determined by ELISA, and seven MPXV genomes were sequenced...

BACKGROUND: Penile cosmetic enhancement procedures have been performed for many years with varying success. However, they have historically been relegated to niche areas of sexual medicine, with limited data, and have not achieved mainstream adoption. More recently, the topic has been increasingly discussed within academic congresses due to availability of novel techniques, therapies, and procedures. Given their distinctive nature, the Sexual Medicine Society of North America (SMSNA) felt that it was pertinent to develop formal position statements to help guide both patients and sexual medicine providers on the current state of the scientific literature and to give recommendations for future research...

PREMISE: Numerous studies have found a positive association between dioecy and polyploidy; however, this association presents a theoretical conflict: While polyploids are predicted to benefit from self-reproduction for successful establishment, dioecious species cannot self-reproduce. We propose a theoretical framework to resolve this apparent conflict. We hypothesize that the inability of dioecious species to self-reproduce hinders their establishment as polyploids. We therefore expect that genera with many dioecious species have fewer polyploids, leading to a negative association between polyploidy and dioecy across genera...

Sexual and gender minority (SGM) adults in South Africa face high levels of violence and poor mental health outcomes. Interventions to prevent these negative health implications are hampered by a lack of representative data among this population. This study aims to quantify the associations between three forms of violent victimization and depressive symptoms in a sub-sample of SGM drawn from a population-based cross-sectional study in Gauteng, South Africa. Data come from the sixth Quality of Life survey conducted in South Africa's Gauteng province...

Understanding socio-cultural factors that influence older (age 50 and up) Black women's risk for sexually transmitted HIV has often been absent from policies and programs. This scoping review asked: What does academic literature reveal about forced/coerced sterilization as a risk factor for older Black women who are disproportionately affected by sexually transmitted HIV? Using the Arksey and O'Malley scoping review methodology, the authors identified academic and gray literature published between 2000 and 2023...

BACKGROUND: Increasing diversity has become a priority for all fields working with human subjects due to historic exclusions and misrepresentations of participants with minoritized identities. To create a more representative and generalizable science of alcohol use, the Research Society on Alcohol (RSA) and its official journal, Alcohol: Clinical and Experimental Research (ACER), have increasingly incorporated diversity and inclusion into their posted values and programming. METHODS: We analyzed the content of articles published in ACER from 2010 through 2022 (6 years before and after the formation of RSA's Diversity Committee) to assess the reporting of participants' demographic information and whether there has been increased inclusion of diverse samples in alcohol research over time...

Objective: to examine factors associated with cigarette and hookah smoking among Middle Eastern (ME) Arab college women. Participants: 406 adult women of ME Arabic background, currently enrolled in or recently graduated from a US college. Methods: a cross-sectional design, using an anonymous online survey of demographic characteristics, sociocultural factors, and access to health care factors. Data analysis included regression model to identify predictors of smoking behaviors. Results: Smoking rates were 21% and 19% for cigarette and hookah smoking...

Our previous research demonstrated that allergic rhinitis could impact behavior and seizure threshold in male mice. However, due to the complex hormonal cycles and hormonal influences on behavior in female mice, male mice are more commonly used for behavioral tests. In this study, we aimed to determine whether these findings were replicable in female mice and to explore the potential involvement of sexual hormones in regulating neuroinflammation in an allergic model. Our results indicate that pain threshold was decreased in female mice with allergic rhinitis and the levels of IL-23/IL-17A/IL-17R were increased in their Dorsal root ganglia...

Prolonged exposure therapy (PE) is a well-established first-line treatment for posttraumatic stress disorder (PTSD) that is based on emotional processing theory. PE has been rigorously evaluated and tested in a large number of clinical trials in many countries covering a wide range of trauma populations. In this review, we summarize the evidence base supporting the efficacy of PE across populations, including adults with sexual assault-related PTSD and mixed trauma-related PTSD, military populations, and adolescents...

INTRODUCTION: Adolescent North Korean defectors are vulnerable due to harmful environments during defection, limited access to sex education in North Korea, and exposure to different sexual norms in South Korea. The purpose of this study was to investigate the sexual knowledge, attitudes, and sex education needs of North Korean refugee adolescents. METHODS: A cross-sectional, descriptive survey was administered to 102 North Korean refugee adolescents. RESULTS: The correct answer rate for questions on genital anatomy, physiology, masturbation, and contraception was less than 20%...
