BACKGROUND: Young men living in Dar es Salaam's informal settlements face environmental stressors that may expose them to multiple determinants of HIV risk including poor mental health and risky sexual behavior norms. We aimed to understand how these co-occurring risk factors not only independently affect men's condom use and sexual partner concurrency, but also how they interact to shape these risk behaviors. METHODS: Participants in the study were male members of 59 social groups known as "camps" in Dar es Salaam, Tanzania...

Costly sexually selected weapons are predicted to trade off with postcopulatory traits, such as testes. Although weapons can be important for achieving access to females, individuals of some species can permanently drop (i.e. autotomize) their weapons, without regeneration, to escape danger. We capitalized on this natural behavior to experimentally address whether the loss of a sexually selected weapon leads to increased testes investment in the leaf-footed cactus bug, Narnia femorata Stål (Hemiptera: Coreidae)...

John S Murray
The purpose of this article was to describe the phenomenon of toxic stress and its impact on the physical and mental health of child refugees. Almost two decades ago, researchers found that recurring adverse childhood events (ACEs; e.g., physical, psychological, and sexual abuse, neglect, and household dysfunction such as substance abuse, mental illness, and criminal behavior) were associated with a significant increase in serious illnesses during adulthood. Illnesses include heart, lung, and liver disease, cancer, and bone fractures...

Pheromones are crucial for eliciting innate responses and inducing social and sexual behaviors in mammals. The vomeronasal receptor 1 genes, V1Rs, encode members of a pheromone receptor family that are mainly expressed in the vomeronasal organ (VNO). The V1R family shows extraordinary variety in gene number among vertebrates owing to successive gene gains and losses during evolution. Such diversity is believed to reflect a degree of dependence on the VNO. We investigated V1R evolution in primate lineages closely related to humans because these VNOs show a trend toward degeneration...

CASE DESCRIPTION A 10-year-old sexually intact male client-owned Texas rat snake (Elaphe obsoleta lindheimeri) was referred for evaluation because of a 5-month history of progressive bilateral ocular opacities and abnormal behavior. CLINICAL FINDINGS On ophthalmic examination, the snake had bilateral mature cataracts and uveal cysts. No additional ophthalmic or physical abnormalities were detected. Results of CBC, serum biochemical analysis, and ocular ultrasonography were unremarkable. TREATMENT AND OUTCOME Bilateral spectaculotomy was performed, followed by bilateral phacoemulsification and uveal cyst aspiration, without complication...

PURPOSE: Substance use has been linked to the sexual transmission of HIV among gay, bisexual, and other men who have sex with men (MSM) across the lifespan. Among older, HIV-positive, MSM populations, cognitive dysfunction associated with age and HIV disease progression also may play a role in sexual risk-taking. People aged 50 years and older represent a growing proportion of the overall HIV-positive population. This study aimed to explore relationships between substance use and cognitive function, and their impact on condomless anal sex (CAS) among HIV-positive gay, bisexual, and other MSM aged 50 years and older...

OBJECTIVE: Victims' conceptualizations of traumatic experiences can impact screening responses and decisions to utilize health care. Despite experiencing events constituting sexual harassment, many victims do not label their experiences as such. In the military, specific situational factors (e.g., occurred on-duty, higher ranking harasser) and victim appraisals of experiences (e.g., offensive, threatening) have been associated with increased labeling of sexual harassment. However, no research has examined sexual harassment labeling among those deployed in recent Afghanistan and Iraq conflicts, where the context of harassment may differ from peacetime settings...

Pedophilia refers to the recurrent, intense sexual interest in prepubescent children who, by definition, have not developed any secondary sex characteristics. Researchers have begun to investigate whether persons with pedophilia are qualitatively different from those without pedophilia (pedophilia is a taxon) or if people vary in their level of sexual interest toward children (pedophilia is dimensional). Two relatively small studies have previously attempted to address this question, but produced conflicting results...

This study assessed whether trajectories of parental monitoring components were different for sexual minority girls (SMGs) compared to heterosexual girls. We recruited 14-19-year-old girls from two adolescent medicine clinics. We estimated growth curve models to compare how components of parental monitoring-adolescent disclosure, parental solicitation, and parental knowledge-changed over 2 years for SMGs and heterosexual girls. SMGs and heterosexual girls had similar trajectory slopes and quadratic forms of adolescent disclosure, but SMGs had consistently lower adolescent disclosure scores...

Research has provided support for the dual systems model of adolescent risk taking, but the model has rarely been applied to sexual behavior. Using data from the NICHD SECCYD (N = 958; Mage = 15.07, SD = 0.18), this study examined the effects of cognitive control, reward seeking, and their interaction on sexual behavior. Results of structural equation models revealed that performance on behavioral tasks assessing reward seeking and cognitive control uniquely predicted sexual intercourse, but the interaction between them was not significant...

This study used latent class analysis to identify patterns (i.e., classes) across a broad range of online sexual experiences among female adolescents (n = 312) and to explore offline sexual behavior and substance use correlates of as well as maltreatment differences in class membership. The following four classes were identified: Online Abstinent, Online Inclusive, Attractors, and Seekers. Maltreated female adolescents were more likely to be members of the Online Inclusive class and less likely to be members of the Online Abstinent class than nonmaltreated female adolescents...

Climate change and the resulting changes in air temperature are known to have a major influence on most animals, especially poikilothermic insects, because they depend on the high enough temperatures to function. Previous studies have shown that various signals can be affected by changes in temperature. However, research into the effect of temperature on mating signals and subsequently communication between mates and on female choice is still rare. In the red mason bee, Osmia bicornis, which emerges early in spring and is therefore subject to extensive temperature changes, females choose suitable males based on, among other criteria, their thorax vibrations and odor...

The current study utilized a longitudinal design to explore the effect of early child impulsivity and rejecting parenting on the development of problematic behaviors in adolescence and early adulthood. Using a low-income sample of 310 mothers and their sons, we examined the direct and interactive effects of child impulsivity and rejecting parenting at age 2 on aggression and substance use at ages 12, 15, and 22, as well as risky sexual behavior at ages 15 and 22. Results revealed that rejecting parenting at age 2 predicted greater aggression at age 12 and risky sexual behavior at ages 15 and 22...

In the United States young men who have sex with men have higher rates of substance use, higher HIV incidence, and less frequent HIV testing than their heterosexual counterparts and older MSM. Less is known about comparable populations in Latin America. As part of an epidemiological study, MSM were recruited through Respondent Driven Sampling in the metropolitan area of Buenos Aires, Argentina and answered a computerized behavioral survey. From the total of 500 MSM enrolled, a sub-sample of 233 aged 18-25 was analyzed...

Non-bizarre delusion, defined as a false belief possible although highly unlikely, is the main manifestation of delusional disorders, previously known as paranoia. Based on the predominant delusional themes, 5 main subtypes may be described - erotomanic, grandiose, jealous, persecutory, and somatic. We present here 2 main delusional disorders, the De Clérambault syndrome and the Othello syndrome, and another closely related to the previous ones - Folie à deux. In the De Clérambault syndrome, the main delusional theme is erotomanic type, related to passional delirium where the patient has strong sexual feelings towards another person and has the belief that this other person is deeply in love with him or her...

BACKGROUND: Young men can be difficult to engage in health research using traditional methods of recruitment. Social networking sites are increasingly being used to recruit participants into health research, due to their cost effectiveness, overall generalizability, and wide reach. OBJECTIVE: The aim of this study was to determine the feasibility of using Facebook to recruit young Australian men into a human papillomavirus (HPV) prevalence study. METHODS: We recruited male permanent residents of Australia, aged 18 to 35 years, into the HPV in Young Males (HYM) study through targeted advertising placed on Facebook...

INTRODUCTION: Testosterone is known to regulate male sexual interest, but the exact way that androgens influence men's sexual cognition remains unclear. AIM: To investigate the influence of androgen deprivation (AD) on visual responses to sexually suggestive stimuli in men treated for prostate cancer with AD therapy. METHODS: Patients with AD-treated prostate cancer, patients with prostate cancer not on AD therapy, and age-matched healthy control participants were exposed to images of male and female runway models fully or minimally clothed...

BACKGROUND: Despite the introduction of HPV vaccines, the incidence of HPV-related cancers (cervical, penile, anal, vulvar, vagina, head, and neck) in sub-Saharan Africa has been rising. The increasing incidence of these HPV-related cancers has been attributed to changes in lifestyle-related risk factors, most notably sexual behavior. The main objective of this study is to map evidence on the distribution of HIV-related cancers in sub-Saharan Africa (SSA). METHODS AND ANALYSIS: We will conduct a scoping review to explore, describe, and map literature on the distribution of HPV-related cancers in sub-Saharan Africa...

Men who have sex with men (MSM) who attend group-sex events often engage in risky sexual behaviors that contribute to the high human immunodeficiency virus (HIV) incidence among this population. We conducted an online survey with 211 New York City MSM who attended sex parties in the prior year and asked them to describe their behaviors and perceptions of risk. We compared responses from HIV-positive-undetectable men (n = 36), HIV-negative men on pre-exposure prophylaxis (PrEP; n = 62), and HIV-negative men never on PrEP (n = 113)...

OBJECTIVE: Conflicting research findings on the association of obesity and pregnancy intention may be due to their collective definition of obesity at a body mass index of 30 kg/m(2) or greater. However, obese women with a BMI of 40 kg/m(2) or greater may be both behaviorally and clinically different from obese women with a lower BMI. This study reexamines this relationship, stratifying by class of obesity; the study also explores variations in contraceptive use by class of obesity given their potential contribution to the incidence of unintended or unwanted pregnancy...
