BACKGROUND: Prescription drug, e-cigarette, smokeless tobacco, and synthetic marijuana use has risen dramatically in the United States over the past decade. OBJECTIVES: This paper investigates the use of risky substances among adolescents, and examines disparities between sexual minority (i.e., mostly heterosexual and lesbian, gay, bisexual; LGB) and heterosexual adolescents in use of novel and emerging substances. Given the public health risk and the imminence of these substances in the media, emerging drug use was examined in a county wide sample of adolescents in a Southern state...

This exploratory study assessed physiological, behavioral, and self-report measures of sexual and romantic indicators of sexual orientation identities among young men (mean age = 21.9 years) with predominant same-sex sexual and romantic interests: those who described themselves as bisexual leaning gay (n = 11), mostly gay (n = 17), and gay (n = 47). Although they were not significantly distinguishable based on physiological (pupil dilation) responses to nude stimuli, on behavioral and self-report measures a descending linear trend toward the less preferred sex (female) was significant regarding sexual attraction, fantasy, genital contact, infatuation, romantic relationship, sex appeal, and gazing time to the porn stimuli...

The negative impact of discrimination on mental health among lesbian, gay, and bisexual populations has been well documented. However, the possible mediating roles of sexual orientation rejection sensitivity and rejection-based proximal stress in the association between discrimination and internalizing symptoms remain unclear. Rejection-based proximal stress is a subset of proximal stressors that are theorized to arise from concerns about and expectations of sexual orientation-based rejection and discrimination...

The existing literature has identified that beliefs about the interpersonal meaning of condom use are a significant predictor of condomless anal sex (CAS). Some have suggested that condom use in this context may function as a form of nonverbal communication. This study utilized attachment theory as a framework and tested a hypothesized model linking adult attachment to CAS through communication skills and condom expectancies. An online survey was completed by 122 single, HIV-negative gay and bisexual (GB) men living in the U...

BACKGROUND: Reconstruction of extensive penoscrotal defects is a surgical challenge. Resurfacing defects in highly complex three-dimensional structures and restoring their function are an essential part of the reconstruction of penoscrotal regions. OBJECTIVE: We describe a technique using internal pudendal artery perforator (IPAP) pedicled propeller flaps created from the gluteal fold. This could be a reliable surgical option that maintains a natural looking scrotal pouch with minimal donor site morbidity and optimal sexual activity...

The prevalence of diagnosed human immunodeficiency virus (HIV) infection in Hispanics/Latinos in the United States is more than twice as high as the prevalence among non-Hispanic whites (1). Services that support retention in HIV medical care and assist with day-to-day living, referred to here as ancillary services, help persons living with HIV access HIV medical care, adhere to HIV treatment, and attain HIV viral suppression. The needs for these ancillary services among Hispanics/Latinos are not well described (2)...

OBJECTIVES: To compare changes in self-reported sexual orientation of women living in states with any recognition of same-sex relationships (e.g., hospital visitation, domestic partnerships) with those of women living in states without such recognition. METHODS: We calculated the likelihood of women in the Nurses' Health Study II (n = 69 790) changing their reported sexual orientation between 1995 and 2009. RESULTS: We used data from the Nurses' Health Study II and found that living in a state with same-sex relationship recognition was associated with changing one's reported sexual orientation, particularly from heterosexual to sexual minority...

Research on gay and bisexual men's sexual position self-label (i.e., being a top, bottom, or versatile during anal sex) has revealed only independent snapshots of its development by focusing primarily on the influence of penis size. Moreover, the basic chronology of development of the sexual position self-label has barely been addressed. In response, we implemented a survey of 282 gay and bisexual men that measured demographics (including height and penis size), age of sexual recognitions, sexual position self-label, and attitudinal constructs suggested by previous literature as important (e...

To our knowledge, this is the first large study of the attractions of child-attracted men recruited in any manner other than their being charged with legal offenses. We recruited 1,189 men from websites for adults attracted to children. Men in our sample were highly attracted to children, and they were much less attracted to adults, especially to adult men. However, men varied with respect to which combination of gender and age they found most attractive. Men in our sample were especially attracted to pubescent boys and prepubescent girls...

Recent research has documented large and robust sex differences in the category specificity of self-reported sexual attraction and viewing times to men and women, with men showing more polarized responses to the two sexes than women. However, this research has been limited by the use of small and restricted samples. To address this, the current study assessed a representative sample of more than 2800 U.S. adults on demographic and attitudinal variables and on two measures of category specificity: one based on self-reported sexual attraction and the other based on viewing times to male and female swimsuit models...

PURPOSE: Health services research involving lesbian, gay, bisexual, transgender, queer, and questioning (LGBTQ) individuals has focused on differences in healthcare access, use, and experiences between cisgender, heterosexual adults and LGBTQ adults. Yet these factors may differ within the LGBTQ community and have not been well-studied among emerging adults (18-29 years), a group with unique barriers to healthcare. We sought to characterize healthcare challenges within a sample of LGBTQ emerging adults...

PURPOSE: HIV disproportionately impacts young black men who have sex with men (YBMSM). Preexposure prophylaxis (PrEP) is an effective strategy that can avert new HIV infections in YBMSM. Barriers exist for YBMSM to access PrEP. METHODS: We sought to determine factors associated with awareness of and willingness to take PrEP in a sample of YBMSM. RESULTS: Only 8% were currently on PrEP despite many (66%) reporting condomless anal sex, a recent provider visit (54%), disclosing their sexual orientation to their regular medical provider (62%), or a willingness to take PrEP (62%)...

In the World Health Organization's forthcoming eleventh revision of the International Classification of Diseases and Related Health Problems (ICD-11), substantial changes have been proposed to the ICD-10 classification of mental and behavioural disorders related to sexuality and gender identity. These concern the following ICD-10 disorder groupings: F52 Sexual dysfunctions, not caused by organic disorder or disease; F64 Gender identity disorders; F65 Disorders of sexual preference; and F66 Psychological and behavioural disorders associated with sexual development and orientation...

In Brazil, there is a deficit of culturally adapted tools to assess prejudice against sexual and gender diversity with empirically demonstrable validity and reliability. Prejudice against non-heterosexual orientations is a strong problem within Brazilian culture and is particularly related to non-normative expressions of gender. To address these issues, a scale was created. The objective of this article is to validate the revised version of this instrument developed for the specificities of Brazilian culture and establish its reliability...

Progress in analyzing and interpreting the concepts of sexual orientation and gender identity in the context of refugee law has contributed to a rise in individuals seeking asylum in such countries as the United States and Canada. However, few studies have examined the victimization experiences of sexual- and gender-identity forced migrants prior to their arrival in North America. This qualitative study used thematic analysis to explore the premigration adult victimization experiences of 26 lesbian, gay, and transgender individuals who obtained refugee, asylee, or withholding-of-removal status in the United States or Canada based on persecution for their sexual orientation and/or gender identity...

Sexual minorities and racial minorities experience greater negative impact following sexual assault. We examined recovery from sexual assault among women who identified as heterosexual and bisexual across racial groups. A community sample of women (N = 905) completed three yearly surveys about sexual victimization, recovery outcomes, race group, and sexual minority status. Bisexual women and Black women reported greater recovery problems. However, Black women improved more quickly on depression symptoms than non-Black women...

A two-part latent growth mixture model was implemented in order to examine heterogeneity in the growth of sexual harassment (SH) victimization in college and university students, and the extent to which SH class membership explains substance use and mental health outcomes for certain groups of students. Demographic risk factors, mental health, and substance use were examined as they related to chronically experienced SH victimization. Incoming freshmen students (N = 2855; 58% female; 54% White) completed a survey at five time points...

BACKGROUND: The main objective of the TAK project is investigating barriers in accessing HIV care after HIV-diagnosis at the CBVCTs of central Poland. Here we describe factors associated with and changes over time in linkage to care and access to cART. METHOD: Data collected in 2010-2013 in CBVCTs were linked with HIV clinics records using unique identifiers. Individuals were followed from the day of CBVCTs visit until first clinical visit or 4/06/2014. Cox-proportional hazard models were used to identify factors associated with being linked to care and starting cART...

AIMS AND OBJECTIVES: To examine patients' perceptions of being asked about their sexual orientation and gender identity in the health care setting. BACKGROUND: Health disparities exist in the lesbian, gay, bisexual and transgender (LGBT) population but further research is needed to better understand these disparities. To address this issue experts recommend the routine collection of sexual orientation and gender identity data in healthcare. Nurses on the front line of patient care play a key role in the collection of this data...

Nitric oxide synthase (NOS) produces nitric oxide (NO) by catalyzing the conversion of l-arginine to l-citrulline, with the concomitant oxidation of nicotinamide adenine dinucleotide phosphate. Recently, various studies have verified the importance of NOS invertebrates and invertebrates. However, the NOS gene family in the oriental river prawn Macrobrachium nipponense is poorly understood. In this study, we cloned the full-length NOS complementary DNA from M. nipponense (MnNOS) and characterized its expression pattern in different tissues and at different developmental stages...
