RESUMEN
Background: Many women who inject drugs are aware of the associated risks, however social influences play a part in their behavioral decisions. Incorporation of others in drug use behaviors may be common practice among women who use drugs. The aim of this study was to gain an in-depth understanding of women's injection drug use experiences with a focus on interpersonal involvement. Methods: Venue-based recruitment was conducted in collaboration with a harm reduction program. A group of 30 women, ages 18 and older, who reported injecting drugs within the past 30 days took part in a demographic survey and semi-structured interview to gain an understanding of their injection practices. In vivo coding and thematic analysis were conducted. Results: Three main themes that relate to incorporating others into injection drug behaviors surfaced, including: (1) injection practices described as we and not I, (2) partnered purchase and drug preparation, and (3) assisted injection. This group of women most often incorporated sexual and/or romantic partners (same and other-gender), friends, or family members into their injection drug use behaviors. Some women described a lack of ability to inject themselves and require assistance every time they use. Women also reported helping other women during drug use behaviors. Conclusions: Our primary themes indicate that a variety of relationship partners are important conceptual links in theoretical frameworks explaining drug use behaviors among women. Findings suggest same gender assistance during drug use behaviors, including injection, that may reduce harm. The interpersonal nature of injection drug use among women may indicate the expansion of treatment options designed for couples or other relationship partners, such as family, together.

Pre-exposure prophylaxis (PrEP) efficacy in preventing HIV among gay, bisexual, and other men who have sex with men (MSM) is dependent upon adherence. Little is known about the PrEP adherence experiences among MSM who live in rural areas of the US. This qualitative study was informed by a modified version of Straussian Grounded Theory. Thirty-four 34 rural Midwestern MSM participated in telephone interviews that assessed their PrEP adherence factors. Overall, participants adhered to the PrEP regimen, ranging from missing none to a couple of doses per month. Participants had high self-efficacy (competence) and self-reliance (autonomy) in taking PrEP daily. Participants incorporated PrEP into their already existing routines. Participants were motivated to adhere to prevent HIV acquisition and be financially responsible. All participants mentioned their PrEP provider discussed the importance of adherence with PrEP's effectiveness, but future patient-provider PrEP adherence communication varied among participants. Future PrEP adherence interventions should address counseling strategies that leverage these constructs to support pill taking. Future research should explore patient-provider conversations surrounding PrEP adherence to inform provider- and patient-level interventions.

Facilitators and barriers of Pre-exposure Prophylaxis (PrEP) uptake have been established in prior studies; however, most of these studies comprise samples of MSM from metropolitan cities and hypothetical PrEP use. There is a dearth of literature on the uptake factors among rural U.S. MSM who are prescribed PrEP. Thirty-four rural Midwestern MSM who currently take PrEP participated in semi-structured telephone interviews about their barriers and facilitators to their PrEP use. Interviews were analyzed using an inductive thematic analysis approach. There were four barriers: (1) lack of rural dissemination of PrEP information, (2) concern about side and adverse effects of using PrEP, (3) cost of PrEP uptake and engagement, and (4) lack of access to PrEP care and PrEP care quality. Individual and social facilitators that participants utilized to overcome these barriers are discussed. Findings elevate the importance of multilevel interventions that address PrEP adoption from a patient, provider, and healthcare system perspective.

Using data from 78 sexting-experienced adolescents from the 2015 National Survey of Sexual Health and Behavior, we describe sexting frequency, sexting partners, sexual relationships with such partners, and characteristics associated with sexting. Most (59.2%) respondents sexted at most monthly, usually with romantic partners (62.0%). About 41% of sexting-experienced adolescents did not usually have sexual relationships with sexting partners, 36.6% usually sexted after starting a sexual relationship, and 16.8% reported that their sexting typically preceded sexual relationships. Younger adolescents sexted more frequently. Those without vaginal sex/anal sex experience, or prior romantic experience, were more likely to have sexted a non-romantic/sexual partner.

Using data from the 2014 National Survey of Sexual Health and Behavior, a probability survey of Americans aged 14+, we assessed the prevalence and correlates of kissing, cuddling, and massage during 1,493 individuals' most recent sexual event from the past year. Most respondents reported kissing (87%) and cuddling (70%); fewer (23%) reported massage. Each was significantly associated with age, education, and relationship structure. Respondents younger than 30 were significantly more likely to indicate they did not kiss because kissing would have been too intimate with their partner. Only cuddling was significantly associated with event-level emotional intimacy and sexual pleasure.

Sexual orientation is a multi-dimensional concept, at a minimum comprised of sexual identity, sexual attraction, and sexual behavior. Our study aimed to assess relationships among self-identified sexual identity, sexual attraction, and sexual behaviors in a probability sample of adults in the U.S. and to identify associated factors with diverse patterns. We collected data from adults in the 2015 National Survey of Sexual Health and Behavior, an Internet-based nationally representative probability survey of the general U.S. population. Concordance between sexual identity versus sexual attraction and sexual behaviors was assessed using percent agreement. We identified correlates of discordance using logistic regression. Concordance between sexual identity versus sexual attraction and past-year sexual behaviors was 94% and 96%, respectively, though our sample was predominately composed of heterosexual individuals. Women and sexual minority individuals reported greater discordance across sexuality-related measures than men and heterosexual individuals. Younger adults (aged 18-24 years) were more likely to report sexual behaviors discordant with sexual identity compared with older adults (including those ages 25-34 years). Higher levels of educational attainment were significantly associated with less discordance of reported recent sexual activity and sexual identity. Measures of sexual identity, attraction, and behaviors are not interchangeable. Future research should consider multiple sexuality-related measures in order to capture the complexity and variability of sexualities.

High-entropy compounds with compositional complexity can be designed as new thermoelectric materials. Here a data-driven model was developed, which chose suitable elements to reduce the enthalpy of formation and hence to increase the chance of single phase formation. Using this model, two high-entropy sulfides were designed, metallic Cu5SnMgGeZnS9 and semiconducting Cu3SnMgInZnS7. They were then successfully fabricated as single-phase dense ceramics with homogeneously distributed cations, and their phase stability and atomic local structures were investigated using density functional theory calculations. Finally, a zT value of 0.58 at 773 K was obtained for Cu5Sn1.2MgGeZnS9, where additional Sn was used to tune the carrier concentration. This work provides a simple approach to find new high-entropy functional materials in the largely unexplored multielement chemical space.
RESUMEN
The quaternary AgPb18SbTe20 compound (abbreviated as LAST) is a prominent thermoelectric material with good performance. Endotaxially embedded nanoscale Ag-rich precipitates contribute significantly to decreased lattice thermal conductivity (κlatt) in LAST alloys. In this work, Ag in LAST alloys was completely replaced by the more economically available Cu. Herein, we conscientiously investigated the different routes of synthesizing CuPb18SbTe20 after vacuum-sealed-tube melt processing, including (i) slow cooling of the melt, (ii) quenching and annealing, and consolidation by (iii) spark plasma sintering (SPS) and also (iv) by the state-of-the-art flash SPS. Irrespective of the method of synthesis, the electrical (σ) and thermal (κtot) conductivities of the CuPb18SbTe20 samples were akin to those of LAST alloys. Both the flash-SPSed and slow-cooled CuPb18SbTe20 samples with nanoscale dislocations and Cu-rich nanoprecipitates exhibited an ultralow κlatt â¼ 0.58 W/m·K at 723 K, comparable with that of its Ag counterpart, regardless of the differences in the size of the precipitates, type of precipitate-matrix interfaces, and other nanoscopic architectures. The sample processed by flash SPS manifested higher figure of merit ( zT â¼ 0.9 at 723 K) because of better optimization and a trade-off between the transport properties by decreasing the carrier concentration and κlatt without degrading the carrier mobility. In spite of their comparable σ and κtot, zT of the Cu samples is low compared to that of the Ag samples because of their contrasting thermopower values. First-principles calculations attribute this variation in the Seebeck coefficient to dwindling of the energy gap (from 0.1 to 0.02 eV) between the valence and conduction bands in MPb18SbTe20 (M = Cu or Ag) when Cu replaces Ag.
RESUMEN
OBJECTIVE: To examine knowledge of Zika transmission and risk perception and to assess variability by condom use in a probability sample of sexually-active adults in the United States. METHODS: Data for this study came from the 2016 wave of the National Survey of Sexual Health and Behavior, a nationally representative probability sample of adults in the United States. Data were collected in November 2016 via a cross-sectional Internet-based survey administered to members of a Knowledge Panel, an address-based random sample service managed by GfK. A weighted subsample (n = 1 713) of sexually active adults, 18 - 50 years of age, was included in analyses. RESULTS: More than 90% of men and women reported low or no perceived risk of Zika. Most participants identified mosquito bite as a route of transmission, while significantly fewer identified sexual intercourse (≈ 40%) and vertical (29% men, 41% women) transmission routes. CONCLUSION: Sexually-active adults in the United States, especially young men, lack awareness of sexual and vertical transmission of Zika Virus. Given the likely endemic nature of Zika, this low-risk perception is an important prevention challenge. Zika prevention messaging should address lesser known transmission routes, emphasize male education, and promote correct and consistent condom use.
RESUMEN
Partnerships between academic and clinical-based health organizations are becoming increasingly important in improving health outcomes. Mutuality is recognized as a vital component of these partnerships. If partnerships are to achieve mutuality, there is a need to define what it means to partnering organizations. Few studies have described the elements contributing to mutuality, particularly in new relationships between academic and clinical partners. This study seeks to identify how mutuality is expressed and to explore potential proxy measures of mutuality for an alliance consisting of a hospital system and a School of Public Health. Key informant interviews were conducted with faculty and hospital representatives serving on the partnership steering committee. Key informants were asked about perceived events that led to the development of the Alliance; perceived goals, expectations, and outcomes; and current/future roles with the Alliance. Four proxy measures of mutuality for an academic-clinical partnership were identified: policy directives, community beneficence, procurement of human capital, and partnership longevity. Findings can inform the development of tools for assisting in strengthening relationships and ensuring stakeholders' interests align with the mission and goal of the partnership by operationalizing elements necessary to evaluate the progress of the partnership.

INTRODUCTION: Although a large body of previous research has examined sexual behavior and its relation to risk in men of diverse sexual identities, most studies have relied on convenience sampling. As such, the vast majority of research on the sexual behaviors of gay and bisexual men, in particular, might not be generalizable to the general population of these men in the United States. This is of particular concern because many studies are based on samples of men recruited from relatively "high-risk" venues and environments. AIMS: To provide nationally representative baseline rates for sexual behavior in heterosexual, gay, and bisexual men in the United States and compare findings on sexual behaviors, relationships, and other variables across subgroups. METHODS: Data were obtained from the 2012 National Survey of Sexual Health and Behavior, which involved the administration of an online questionnaire to a nationally representative probability sample of women and men at least 18 years old in the United States, with oversampling of self-identified gay and bisexual men and women. Results from the male participants are included in this article. MAIN OUTCOME MEASURES: Measurements include demographic characteristics, particularly sexual identity, and their relations to diverse sexual behaviors, including masturbation, mutual masturbation, oral sex, vaginal sex, and anal sex. Behaviors with male and female partners were examined. RESULTS: Men of all self-identified sexual identities reported engaging in a range of sexual behaviors (solo and partnered). As in previous studies, sexual identity was not always congruent for gender of lifetime and recent sexual partners. CONCLUSION: Patterns of sexual behaviors and relationships vary among heterosexual, gay, and bisexual men. Several demographic characteristics, including age, were related to men's sexual behaviors. The results from this probability study highlight the diversity in men's sexual behaviors across sexual identities, and these data allow generalizability to the broader population of gay and bisexual men, in particular, in the United States, which is a major advancement in research focused on individuals in a sexual minority.

Little is known about current attitudes in the United States toward having sex during pregnancy. It is possible that pregnant women and their sexual partners hold beliefs and have feelings during this time that might lead to sexual and relational distress. Two new scales, Maternal Sex During Pregnancy and Partner Sex During Pregnancy, were developed and administered to 112 newly pregnant couples. The scales demonstrated strong reliability and validity. Attitudes and beliefs varied across the sample, but the scores did not significantly differ between partners. These scales allow clinicians to support healthy sexuality during pregnancy by understanding sources of anxiety and possible misconceptions.

There is a critical need to understand the interplay between relationship trust and public health outcomes. The purpose of this study was to develop an understanding of emerging adult women's processes of establishing trust in sexual relationships. Twenty-five women aged 18-24 years participated in semi-structured interviews. Throughout the interviews, women compared and contrasted experiences in which they felt comfortable engaging in sexual intercourse with a partner versus times in which they did not feel comfortable. Analysis was based on a critical qualitative research orientation. When asked to speak to instances when they felt comfortable having sex, most women spoke about relationship trust. Many participants conceptualised trust based on past experiences with bad relationships or sexual violence. Based on their previous experiences of feeling unsafe or undervalued, emotional and physical security became prioritised in relationship development. Trust was developed through friendship, communication over time, and through shared life experiences. This research is among the first to qualitatively investigate trust formation and other impersonal dynamics related to sexual health decision-making. Insights from this study should be translated into future action by public health practitioners to promote healthy sexual relationships and communication about sexual health topics as a form of trust building.

INTRODUCTION: Recent U.S. nationally representative data indicate that about 30% of women and 5% of men reported pain occurring during their most recent sexual event; however, little is known about the severity, duration, or context of such pain, or its prevalence during vaginal vs. anal intercourse. AIMS: To document the prevalence and characteristics of pain during vaginal and anal intercourse among U.S. women and men (ages 18+) at their most recent other-sex sexual event, including the self-reported severity, duration, and location of their pain; how participants addressed their pain; and partner communication related to the pain. METHODS: Data from a subsample of 1,738 women and men in the 2012 National Survey of Sexual Health Behavior, a nationally representative probability survey of Americans ages 18+ collected via the Internet, were analyzed. MAIN OUTCOME MEASURES: Participants responded to items about their background characteristics; whether they had vaginal or anal intercourse during their most recent sexual experience; the severity, duration, and location of any pain experienced during said sexual event; and whether they responded to or communicated about the pain. RESULTS: About 30% of women and 7% of men reported pain during vaginal intercourse events, and most of the reports of pain were mild and of short duration. About 72% of women and 15% of men reported pain during anal intercourse events, with more of these events including moderate or severe pain (for the women) and of mixed duration. Large proportions of Americans do not tell their partner when sex hurts. CONCLUSION: Pain is a relatively common, and often not discussed, aspect of both vaginal and anal intercourse events occurring between women and men. Individual and clinical implications are discussed.

INTRODUCTION: The diversity in self-identified lesbian and bisexual women's sexual interactions necessitates better understanding of how and when they integrate personal lubricant into different experiences. However, little is known about lesbian and bisexual women's lifetime lubricant use, particularly at the population level. AIMS: The aim of this study was to examine the prevalence and characteristics of lubricant use among adult lesbian and bisexual women in the United States. METHODS: Data were drawn from a subset of lesbian and bisexual participants who participated in the 2012 National Survey of Sexual Health and Behavior, an online questionnaire administered to a nationally representative probability sample of U.S. adults ages 18 and older. MAIN OUTCOME MEASURES: We examined socio-demographic characteristics, recent and lifetime lubricant use, lubricant use in associated with specific sexual behaviors and condom use, frequency of use, motivations for use, as well as perception of lubricant when used. RESULTS: A majority of lesbian- (60.1%) and bisexual-identified (77.1%) women reported ever using lubricant; 25.7% of lesbian women and 32.7% of bisexual women used it in the last 30 days. Across most age groups, lubricant was commonly used during partnered sexual play, partnered sexual intercourse, or when a vibrator/dildo was used. Lesbian and bisexual women reported using lubricants to increase arousal/sexual pleasure/desire, to make sex more fun, or to increase physical comfort during sex. CONCLUSIONS: Lubricant use is identified as a part of lesbian and bisexual women's sexual experience across the life span, as a part of both solo and partnered experiences. As part of evolving sexual health assessments, clinicians and health educators may find value in integrating lubricant-focused conversation with their lesbian and bisexual patients and clients, particularly.

Previous social and behavioral research on identity among bisexual men, when not subsumed within the category of men who have sex with men (MSM), has primarily focused on samples of self-identified bisexual men. Little is known about sexual self-identification among men who are behaviorally bisexual, regardless of sexual identity. Using qualitative data from 77 in-depth interviews with a diverse sample of behaviorally bisexual men (i.e., men who have had sex with at least one woman and at least one man in the past six months) from a large city in the Midwestern United States, we analyzed responses from a domain focusing on sexual self-identity and related issues. Overall, participants' sexual self-identification was exceptionally diverse. Three primary themes emerged: (1) a resistance to, or rejection of, using sexual self-identity labels; (2) concurrent use of multiple identity categories and the strategic deployment of multiple sexual identity labels; and (3) a variety of trajectories to current sexual self-identification. Based on our findings, we offer insights into the unique lived experiences of behaviorally bisexual men, as well as broader considerations for the study of men's sexuality. We also explore identity-related information useful for the design of HIV/STI prevention and other sexual health programs directed toward behaviorally bisexual men, which will ideally be variable and flexible in accordance with the wide range of diversity found in this population.

Epidemiologic data demonstrate that women involved with the criminal justice system in the United States are at high risk for sexually transmitted infections, including herpes simplex virus type 2 (HSV-2). Female defendants were recruited from a misdemeanor court to assess whether brief framed messages utilizing prospect theory could encourage testing for HSV-2. Participants were randomly assigned to a message condition (gain, loss, or control), completed an interviewer-administered survey assessing factors associated with antibody test uptake/refusal and were offered free point-of-care HSV-2 serologic testing. Although individuals in the loss-frame group accepted testing at the highest rate, an overall statistical difference in HSV-2 testing behavior by group (p ≤ .43) was not detected. The majority of the sample (74.6%) characterized receiving a serological test for HSV-2 as health affirming. However, this did not moderate the effect of the intervention nor was it significantly associated with test acceptance (p ≤ .82). Although the effects of message framing are subtle, the findings have important theoretical implications given the participants' characterization of HSV-2 screening as health affirming despite being a detection behavior. Implications of study results for health care providers interested in brief, low cost interventions are also explored.

Most previous studies of the sexual behaviour of gay, bisexual and other men who have sex with men living with HIV are based on samples of men recruited within relatively urban and suburban areas of the USA. The aim of the present study was to explore the potential challenges associated with HIV-related stigma and residing in a relatively rural area. We conducted a qualitative study based in south-central Indiana, a relatively rural area of the USA. Twenty-three HIV-positive gay, bisexual and other men who have sex with men, aged 21-48 years, were interviewed on topics regarding community engagement, perceived HIV-related stigma, relationship formation, sexual behaviour and HIV status disclosure. Findings indicate HIV-related stigma is commonly reported at the interpersonal and community levels. Because of this, men face complex situations on how and when to disclose their HIV status to members of their social and sexual networks. Although many participants reported many challenges associated with relationship formation, all expressed a desire for romantic and/or sexual connections with other men and/or women. Results suggest that new programmatic approaches are necessary to inform the work of social service and medical providers on mechanisms to intervene and combat stigma and discrimination inherent in communities, programmes and policies.

Many people hold stereotypes and assumptions about religious communities in regards to their feelings and beliefs about sex and the impact it has on the lived experiences of religious people. However, stereotypes and assumptions are not often grounded in reality, and many people are hesitant to address the issue head on. This qualitative ethnographically informed preliminary grounded theory study aimed to engage an Evangelical Pentecostal community in Southern Nigeria with the ultimate goal of understanding how communities conceptualize and discuss sexuality topics, the factors influencing sexual decision making amongst youth and young adults, and to identify research needs that will better inform innovative and efficacious research utilizing religious communities in sexuality research. Results showed that this population was highly interested in discussing sexuality in their community including major threats to their ideal sexual behavior path, reasons why people stray from this ideal and how to keep people on this ideal path. This research demonstrates that religious communities are interested in conducting sexuality research so long as the research takes their values and beliefs into account and respects their limitations when it comes to research intent and methods.

INTRODUCTION: Penile size continues to receive popular and empirical attention. Little is known about the process of self-measurement and whether the behaviors a man engages in to become erect for self-measurement are associated with his erect penile dimensions. AIMS: The article aims to assess men's erect penile dimensions in a study in which the men would presumably be motivated to report accurate information about their penis size; and to explore associations between men's erect penile dimensions, their method of measurement, and their demographics. METHODS: Data are from an Internet-based baseline phase of a large prospective daily diary study that compared men's use of a standard-sized condom to men's use of a condom sized to fit their erect penis. MAIN OUTCOME MEASURES: The main outcomes are participant characteristics, activities engaged in during self-measurement process, and self-reported erect penile length and circumference. RESULTS: For this sample of 1,661 men, the mean erect penile length was 14.15 cm (SD = 2.66; range = 4 to 26 cm), and the mean erect penile circumference was 12.23 cm (SD = 2.23; range = 3 to 19). Participant characteristics were not associated with measured length or circumference. Most men measured their penis while alone, using hand stimulation to become erect. CONCLUSIONS: In this sample of men who measured their erect penile length and circumference for the purposes of receiving a condom sized to fit their erect penis, we found a mean erect penile length of 14.15 cm and a mean erect penile circumference of 12.23 cm. The self-reported erect penile dimensions in this study are consistent with other penile dimension research. Also, findings suggest that mode of getting an erection may influence erect penile dimensions. Additionally, how a man becomes erect for self-measurement may be associated with his erect penile length and/or circumference.
