The origin and function of exaggerated traits exhibited by a great number of species with sexual dimorphism remain largely unexplored. The usual model considered as the evolutionary mechanism for the development of these structures is sexual selection. The nature of growth of the postocular flange (POF) in three species of the dobsonfly genus Platyneuromus (Megaloptera, Corydalidae, Corydalinae) is analyzed to explore sexual size dimorphism and allometric scaling. Results involve positive allometry of POF in males of two species, and negative allometry in males of one species, in general with a female-biased sexual dimorphism...

This study was done to assess the knowledge, attitudes, risky behaviors and preventive practices related to sexually-transmitted diseases (STDs) among health and non-health sciences university students as future healthcare providers in Malaysia. A total of 700 health and non-health sciences university students (255 male; 445 female) aged between 17 and 30 years were surveyed by using a self-administered questionnaire. The majority (86.6%) had heard of STDs, and 50.4% knew STDs could present without symptoms...

BACKGROUND: Although the association between alcohol consumption and HIV risk is well documented, few studies have examined the magnitude of new HIV infections that could be prevented by controlling alcohol use. We report the population attributable fraction (PAF) of incident HIV infections due to alcohol consumption among the HIV high-risk population of fishing communities along Lake Victoria, Uganda. METHODS: In a community-based cohort study, 1607 HIV sero-negative participants aged 18-49 years were enrolled from eight fishing communities along Lake Victoria, Uganda...

Latinas have disproportionally high rates of cervical cancer in part due to their reliance on Latino partners to make sexual health decisions, their limited knowledge about human papillomavirus (HPV), and inconsistent Pap smear screening behaviors. In this qualitative study, we examined the sexual health beliefs of Latino college men regarding HPV. Participants included 6 Mexican American college students from a large Midwestern university. We conducted 18 in-depth individual interviews about men's beliefs, attitudes, and knowledge about HPV...

REVIEW
Faina Gelman, Jessica Atrio
The pathophysiology, diagnosis and treatment of female sexual interest in pre- and post-menopausal women present a complex arena for patients and physicians to navigate. Flibanserin was the first pharmacologic treatment, approved by the United States Food and Drug Administration in August 2015, for hypoactive sexual desire disorder (HSDD) in premenopausal women. Side effects, contraindications and lack of approval in postmenopausal women are all limitations, as are issues surrounding patient and physician knowledge and access...

Sexual assertiveness is an issue of interest in the context of gender equality and sexual health. This study investigated the social tuning hypothesis that encountering a gender-traditional partner would lead to stronger gender-typical behavior, i.e., respectively, higher and lower levels of taking sexual initiative among men and women. Participants (N = 271) read a vignette describing a romantic partner, who was either presented as gender-traditional or not, followed by a sexual scenario. Subsequently, participants were asked about their expectations toward their own sexual initiative taking...

Gene-environment interactions that moderate aggressive behavior have been identified independently in the serotonin transporter (5-HTT) gene and monoamine oxidase A gene (MAOA). The aim of the present study was to investigate epistasis interactions between MAOA-variable number tandem repeat (VNTR), 5-HTTlinked polymorphism (LPR) and child abuse and the effects of these on aggressive tendencies in a group of otherwise healthy adolescents. A group of 546 Chinese male adolescents completed the Child Trauma Questionnaire and Youth self-report of the Child Behavior Checklist...

Population density and associated behavioral adjustments are potentially important in regulating physiological performance in many animals. In r-selected species like the fruit fly (Drosophila), where population density rapidly shifts in unpredictable and unstable environments, density-dependent physiological adjustments may aid survival of individuals living in a social environment. Yet, how population density (and associated social behaviors) affects physiological functions like metabolism is poorly understood in insects...

INTRODUCTION: Postmenopausal women's knowledge about vulvar and vaginal atrophy (VVA) and available treatment options has historically been inadequate. Recent direct-to-consumer marketing and educational efforts would have been expected to increase awareness and treatment options. AIM: To compare results of the Women's EMPOWER survey with other available VVA surveys to assess progress in women's understanding and approaches to treatment of VVA. METHODS: The Women's EMPOWER survey, an internet-based survey of US women with VVA symptoms, assessed women's awareness of VVA and their behaviors and attitudes associated with symptom treatment...

The rate of sexually transmitted infections in the United States increased in 2015 for the second year in a row. Adolescents bear an undue portion of this burden because of increased physiologic susceptibility, higher rates of reinfection, and developmental age. Despite expedited partner therapy (EPT) being legalized in 39 states, health care providers still report infrequently providing EPT to their adolescent patients. Patients who benefit most from EPT include those with high-risk sexual behavior, a steady relationship status, higher education level, or an established relationship with the provider...

This study builds on and extends previous research on nativity variations in adolescent health and risk behavior by addressing three questions: (1) whether and how generational status and age at migration are associated with timing of sexual onset among U.S. adolescents; (2) whether and how family instability mediates associations between nativity and sexual debut; and (3) whether and how these associations vary by gender. We find that first- and second-generation immigrant youth initiate sexual activity later than native youth...

Adolescents who have been adjudicated for illegal sexual behavior may receive treatment that requires attending group therapy sessions and classes. For some adolescents, nonsexual problem behavior (e.g., verbal outbursts, noncompliance) interferes with their ability to participate in group treatment. Researchers used a multiple-baseline across groups design with an embedded changing criterion design to evaluate the effects of an interdependent group contingency for decreasing disruptive behavior in adolescents across two therapy groups...

BACKGROUND: Geographic heterogeneity of human papillomavirus (HPV) involvement in head and neck squamous cell carcinoma (HNSCC) has been observed over the last few years. This trend has not been evaluated in the Philippines. Hence, this study aims to provide for the first time a data on the prevalence of HPV in HNSCC in the northwestern region of the Philippines. METHODS: Two hundred one (201) biopsy samples (179 formalin fixed paraffin embedded and 22 fresh frozen) from 163 Filipino HNSCC cases (oral cavity = 88; larynx = 60; oropharynx = 15) diagnosed between 2003 to 2013 were initially included in this study...

Formerly incarcerated Latino men (FILM) have been significantly impacted by the HIV/AIDS and alcohol abuse epidemics in the United States. In this analysis, we examine the role of social, economic and cultural marginalization in the likelihood of alcohol-related sexual risk taking behavior among FILM. We recruited a non-random sample of FILM, ages 18-49 (n = 259). We performed logistic regression modeling to test four hypotheses examining the direct and moderating effects of socio-cultural factors. Drinking before sex was strongly associated with high likelihood of condomless intercourse (adjusted odds ratio, AOR = 2...

The scientific understanding of fear and anxiety-in both normal and pathological forms-is presently limited by a predominance of studies that use male animals and Pavlovian fear conditioning-centered paradigms that restrict and assess specific behaviors (e.g., freezing) over brief sampling periods and overlook the broader contributions of the spatiotemporal context to an animal's behavioral responses to threats. Here, we use a risky "closed economy" system, in which the need to acquire food and water and the need to avoid threats are simultaneously integrated into the lives of rats, to examine sex differences in mitigating threat risk while foraging...

BACKGROUND: Despite treatment with therapeutic hypothermia (TH), infants who survive hypoxic ischemic (HI) encephalopathy (HIE) have persistent neurological abnormalities at school age. Protection by TH against HI brain injury is variable in both humans and animal models. Our current preclinical model of hypoxia-ischemia (HI) and TH displays this variability of outcomes in neuropathological and neuroimaging end points with some sexual dimorphism. The detailed behavioral phenotype of this model is unknown...

Young men who have sex with men (MSM) of color are at increased risk for HIV infection. Mpowerment (MP) is an intervention designed to reduce risky sexual behavior and increase HIV testing among young MSM ages 18-29. From 2009 to 2012, three community-based organizations with support from the U.S. Centers for Disease Control and Prevention evaluated MP among N = 298 participants. Following a repeated measures design, data from 3- and 6-month follow-ups were compared to baseline. HIV testing and self-efficacy for safer sex increased at both follow-up time points; self-acceptance as an MSM was higher at follow-up 2...

Although there have been great advances in the prevention of HIV in the last two decades, young men who have sex with men (YMSM) continue to be disproportionately impacted. Utilizing qualitative data from a sample of YMSM (N = 292) engaged in a randomized controlled trial testing the efficacy of an internet-based HIV prevention program, we examined YMSM's goals for sexual risk reduction. Goals tended to focus on strategies used to prepare for safer sex or strategies to be used during sex. In both areas, five categories of strategies were identified: skill-related, intrapersonal, social, contextual, and instrumental...

BACKGROUND: Sexual behavior and oral human papillomavirus (HPV) infection are risk factors for oral squamous cell carcinoma (OSCC). The effects of OSCC diagnosis and treatment on subsequent relationship stress and sexual behavior are unknown. METHODS: Incident cases of HPV-positive or HPV-negative OSCC in patients who had a partnered relationship and partners of patients with oropharyngeal cancer were eligible for a study in which surveys were administered at diagnosis and at the 6-month follow-up time point to assess relationship distress, HPV transmission and concerns about health consequences, and sexual behavior...
