Sex with multiple partners, consecutively or concurrently, is a risk factor for contracting sexually transmitted infections (STIs) as multiple partner–partner contacts present increased opportunity for transmission. It is unclear, however, if individuals who tend to have more partners also use protection less reliably than those with sexual histories of fewer partners. Longitudinal data can elucidate whether an individual shows a consistent pattern of sex with multiple partners. We used latent class growth analyses to examine emerging adult survey data (N = 2244) spanning 10 waves of assessment across 6 years. We identified three trajectory classes described with respect to number of partners as (a) Multiple, (b) Single, and (c) Rare. Trajectory group, relationship status, and their interactions were tested as predictors of using protection against STIs and pregnancy at each wave. The Multiple Partners class had the greatest odds ratio of reporting sex without protection against STIs and pregnancy, followed by the Single and Rare classes. Exclusive relationship status was a risk factor for unprotected sex at earlier waves, but a protective factor at most later waves. There was no significant interaction between relationship status and trajectory class in predicting use of protection. The Multiple Partners class reported more permissive values on sex and an elevated proportion of homosexual behavior. This group overlaps with an already identified at-risk population, men who have sex with men. Potential mechanisms explaining the increased risk for sex without protection, including communication, risk assessment, and co-occurring risk behaviors are discussed as targets for intervention.

National estimates suggest intimate partner violence (IPV) rates are equal or higher among lesbian, bisexual, or questioning (LBQ)-identified women than heterosexual-identified women. Women veterans are a population at high risk for IPV, yet the occurrence of lifetime and past-year IPV experiences by sexual orientation have not been examined in this population. Lifetime and past-year IPV experiences and current IPV-related posttraumatic stress disorder (PTSD) symptoms were assessed with validated screening measures as part of a 2014 web-based national survey of women veterans. Among 403 respondents, 9.7% (n = 39) identified as LBQ, and 90.3% (n = 364) identified as heterosexual. When controlling for age, LBQ-identified women veterans were significantly more likely to report lifetime sexual and physical IPV and lifetime intimate partner stalking. In the past year, LBQ-identified veterans were twice as likely to endorse emotional mistreatment and physical IPV, and three times more likely to endorse sexual IPV, than were heterosexual-identified women veterans. However, sexual orientation was unrelated to IPV-related PTSD symptoms, when controlling for age, race, and number IPV forms experienced. IPV is prevalent among LBQ-identified women veterans, suggesting the need to understand the potentially unique contextual factors and health-care needs of this group.

Addressing record high rates of Chlamydia trachomatis incidence in the United States requires the utilization of effective strategies, such as expedited partner therapy, to reduce reinfection and further transmission. Expedited partner therapy, which can be given as a prescription or medication, is a strategy to treat the sexual partners of index patients diagnosed with a sexually transmitted infection without prior medical evaluation of the partners. There are multiple steps in the prescription-expedited partner therapy cascade, and we sought to identify pharmacy-level barriers to implementing prescription-expedited partner therapy for Chlamydia trachomatis treatment. We used spatial analysis and ArcGIS, a geographic information system, to map and assess geospatial access to pharmacies within Baltimore, MD, neighborhoods with the highest rates of Chlamydia trachomatis (1180.25-4255.31 per 100,000 persons). Expedited partner therapy knowledge and practices were collected via a telephone survey of pharmacists employed at retail pharmacies located in these same neighborhoods. Cost of antibiotic medication in US dollars was collected. Census tracts with the highest Chlamydia trachomatis incidence rates had lower median pharmacy density than other census tracts (26.9 per 100,000 vs 31.4 per 100,000, P < .001). We identified 25 pharmacy deserts. Areas defined as pharmacy deserts had larger proportions of black and Hispanic or Latino populations compared with non-Hispanic whites (93.1% vs 6.3%, P < .001) and trended toward higher median Chlamydia trachomatis incidence rates (1170.0 per 100,000 vs 1094.5 per 100,000, P = .110) than non-pharmacy desert areas. Of the 52 pharmacies identified, 96% (50 of 52) responded to our survey. Less than a fifth of pharmacists (18%, 9 of 50) were aware of expedited partner therapy for Chlamydia trachomatis. Most pharmacists (59%, 27 of 46) confirmed they would fill an expedited partner therapy prescription. The cost of a single dose of azithromycin (1 g) ranged from 5.00 to 39.99 US dollars (median, 30 US dollars). Limited geographic access to pharmacies, lack of pharmacist awareness of expedited partner therapy, and wide variation in expedited partner therapy medication cost are potential barriers to implementing prescription-expedited partner therapy. Although most Baltimore pharmacists were unaware of expedited partner therapy, they were generally receptive to learning about and filling expedited partner therapy prescriptions. This finding suggests the need for wide dissemination of educational material targeted to pharmacists. In areas with limited geographic access to pharmacies, expedited partner therapy strategies that do not depend on partners physically accessing a pharmacy merit consideration.

Objective This study proposed and tested the first conceptual model of sexual minority specific (discrimination, internalized homophobia) and more general risk factors (perpetrator and partner alcohol use, anger, relationship satisfaction) for intimate partner violence among partnered lesbian women. Method Self-identified lesbian women (N=1048) were recruited from online market research panels. Participants completed an online survey that included measures of minority stress, anger, alcohol use and alcohol-related problems, relationship satisfaction, psychological aggression, and physical violence. Results The model demonstrated good fit and significant links from sexual minority discrimination to internalized homophobia and anger, from internalized homophobia to anger and alcohol problems, and from alcohol problems to intimate partner violence. Partner alcohol use predicted partner physical violence. Relationship dissatisfaction was associated with physical violence via psychological aggression. Physical violence was bidirectional. Conclusions Minority stress, anger, alcohol use and alcohol-related problems play an important role in perpetration of psychological aggression and physical violence in lesbian women's intimate partner relationships. The results of this study provide evidence of potentially modifiable sexual minority specific and more general risk factors for lesbian women's partner violence. PMID:28239508

This experiment examined the effects of women's relationship motivation, partner familiarity, and alcohol consumption on sexual decision making. Women completed an individual difference measure of relationship motivation and then were randomly assigned to partner familiarity condition (low, high) and to alcohol consumption condition (high dose, low dose, no alcohol, placebo). Then women read and projected themselves into a scenario of a sexual encounter. Relationship motivation and partner familiarity interacted with intoxication to influence primary appraisals of relationship potential. Participants' primary and secondary relationship appraisals mediated the effects of women's relationship motivation, partner familiarity, and intoxication on condom negotiation, sexual decision abdication, and unprotected sex intentions. These findings support a cognitive mediation model of women's sexual decision making and identify how individual and situational factors interact to shape alcohol's influences on cognitive appraisals that lead to risky sexual decisions. This knowledge can inform empirically based risky sex interventions.

OBJECTIVE Little is known about the psychosocial challenges of adults living with type 1 diabetes or its impact on partner relationships. This qualitative study was undertaken to gain better understanding of these issues. RESEARCH DESIGN AND METHODS Four focus groups were held, two with adult type 1 diabetic patients (n = 16) and two with partners (n = 14). Two broad questions were posed: “What are the emotional and interpersonal challenges you have experienced because you have (your partner has) type 1 diabetes?” and “How does the fact that you have (your partner has) type 1 diabetes affect your relationship with your partner, positively and/or negatively?” Sessions were recorded and transcribed, and analyzed by a team of four researchers, using constant comparative methods to identify core domains and concepts. RESULTS Four main domains were identified: 1) impact of diabetes on the relationship, including level of partner involvement, emotional impact of diabetes on the relationship, and concerns about child-rearing; 2) understanding the impact of hypoglycemia; 3) stress of potential complications; and 4) benefits of technology. Themes suggest that, although partner involvement varies (very little to significant), there exists significant anxiety about hypoglycemia and future complications and sources of conflict that may increase relationship stress. Partner support is highly valued, and technology has a positive influence. CONCLUSIONS Adults with type 1 diabetes face unique emotional and interpersonal challenges. Future research should focus on gaining a better understanding of how they cope and the effect of psychosocial stressors and coping on adherence, quality of life, and glycemic control. PMID:23474590

Increasingly, funders and researchers want to partner with patients in health research, but it can be challenging for researchers to find patient partners. More than taking part in research as participants, patient partners help design, carry out and manage research projects. The goal of this study was to describe ways that patient partners have been recruited by researchers and patient engagement leads (individuals within organizations responsible for promoting and supporting patients as research partners). We talked with researchers and patient engagement leads in Canada and the United Kingdom, as well as a patient representative. We found three ways that could help researchers and patients find each other. One way is a case-by-case basis, where patients are often sought with experience of a health condition that is the focus of the research. The other ways involved directories where projects were posted and could be found by patients and researchers, or a third party matched patients with research projects. We found four recruitment strategies:Social marketingCommunity outreachHealth systemPartnering with other organizations (e.g., advocacy groups) There are many influences on finding, selecting and retaining patient partners: patient characteristics, the local setting, the opportunity, work climate, education and support. We hope study results will provide a useful starting point for research teams in recruiting their patient partners. Background Patient engagement in clinical trials and other health research continues to gain momentum. While the benefits of patient engagement in research are emerging, relatively little is known about recruiting patients as research partners. The purpose of this study was to describe recruitment strategies and models of recruiting patients as partners in health research. Methods Qualitative descriptive study. Thirteen patient engagement leads and health researchers from Canada and the United Kingdom, as well as one patient representative from a national patient organization (7 female) completed semi-structured interviews. Results Recruitment infrastructures available to respondents varied, but could be categorized into three models including the traditional, third-party and directory models. Four categories of recruitment strategies were identified, representing multiple ways of recruiting patient partners: social marketing recruitment, community outreach recruitment, health system recruitment, and partnering recruitment. Conclusions Multiple recruitment strategies were identified for engaging patient partners in research, and some common factors influenced recruitment. Study findings contribute to the evidence base in patient engagement and provide guidance for research teams to help identify potential recruitment methods for their patient partners.

Recent studies have called for more nuanced research into the relationships between behaviourally bisexual men and their sexual partners. To address this, we conducted a longitudinal qualitative study with self-identifying gay men; participants took part in timeline-based interviews and relationship diaries. We conducted thematic analysis of verbatim transcripts to understand how relationship motivations, emotions and relationship dynamics influenced perceptions of HIV risk with behaviourally bisexual male partners. Participants described how partnership types (main and casual) and relationship dimensions (exclusivity, commitment, emotional attachment, and relationship designation) strongly influenced perceptions of HIV risk and shaped their decisions to choose behaviourally bisexual male sex partners. Results revealed the crucial role relationship dynamics play in the shaping of HIV risk perceptions, sexual decision-making and HIV risk between partners and provide potential insight on how to message HIV risk to gay men and their behaviourally bisexual male partners. It is imperative that HIV prevention is able to message key concepts of risk, decision-making and partner negotiation in a way that does not act to stereotype or create stigma against behaviourally bisexual men and their male partners.

The Schrodinger equation is the fundamental equation in quantum physics. The characteristic of the particle in physics potential field can be explained by using the Schrodinger equation. In this study, the solution of 4 dimensional Schrodinger equation for the anharmonic potential and the anharmonic partner potential have done. The method that used to solve the Schrodinger equation was the ansatz wave method, while to construction the partner potential was the supersymmetric method. The construction of partner potential used to explain the experiment result that cannot be explained by the original potential. The eigenvalue for anharmonic potential and the anharmonic partner potential have the same characteristic. Every increase of quantum orbital number the eigenvalue getting smaller. This result corresponds to Bohrn’s atomic theory that the eigenvalue is inversely proportional to the atomic shell. But the eigenvalue for the anharmonic partner potential higher than the eigenvalue for the anharmonic original potential.

Overexpression of cyclin D1 and its catalytic partner, CDK4, is frequently seen in human cancers. We constructed cyclin D1 and CDK4 protein interaction network in a human breast cancer cell line MCF7, and identified novel CDK4 protein partners. Among CDK4 interactors we observed several proteins functioning in protein folding and in complex assembly. One of the novel partners of CDK4 is FKBP5, which we found to be required to maintain CDK4 levels in cancer cells. An integrative analysis of the extended cyclin D1 cancer interactome and somatic copy number alterations in human cancers identified BAIAPL21 as a potential novel human oncogene. We observed that in several human tumor types BAIAPL21 is expressed at higher levels as compared to normal tissue. Forced overexpression of BAIAPL21 augmented anchorage independent growth, increased colony formation by cancer cells and strongly enhanced the ability of cells to form tumors in vivo. Lastly, we derived an Aggregate Expression Score (AES), which quantifies the expression of all cyclin D1 interactors in a given tumor. We observed that AES has a prognostic value among patients with ER-positive breast cancers. These studies illustrate the utility of analyzing the interactomes of proteins involved in cancer to uncover potential oncogenes, or to allow better cancer prognosis. PMID:25486477

Thirty years of research show alcohol to be a cause of intimate partner violence: Future research needs to identify who to treat and how to treat them.

Research over the past 30 years has demonstrated that excessive alcohol use meets all of the epidemiological criteria for causality. While neither a necessary nor a sufficient cause, excessive alcohol use does contribute to the occurrence of partner violence and that contribution is approximately equal to other contributing causes such as gender roles, anger and marital functioning. Current theories of how excessive drinking results in partner violence provide a potentially valuable framework with respect to who should be targeted for interventions with respect to alcohol-related partner violence and what those interventions should address. © 2016 The Authors.

Fibroblast growth factor receptors (FGFRs) are a family of four transmembrane (TM) receptor tyrosine kinases (RTKs) which bind to a large family of fibroblast growth factor (FGF) ligands with varying affinity and specificity. FGFR signaling regulates many physiological and pathological processes in development and tissue homeostasis. Understanding FGFR signaling processes requires the identification of partner proteins which regulate receptor function and biological outputs. In this study, we employ an epitope-tagged, covalently dimerized, and constitutively activated form of FGFR1 to identify potential protein partners by MS. By this approach, we sample candidate FGFR effectors throughout the life history of the receptor. Functional classification of the partners identified revealed specific subclasses involved in protein biosynthesis and folding; structural and regulatory components of the cytoskeleton; known signaling effectors and small GTPases implicated in endocytosis and vesicular trafficking. The kinase dependency of the interaction was determined for a subset of previously unrecognized partners by coimmunoprecipitation, Western blotting, and immunocytochemistry. From this group, the small GTPase Rab5 was selected for functional interrogation. We show that short hairpin (sh) RNA-mediated depletion of Rab5 attenuates the activation of the extracellular-regulated kinase (ERK) 1/2 pathway by FGFR signaling. The strategic approach adopted in this study has revealed bona fide novel effectors of the FGFR signaling pathway.

Female sex workers (FSWs) may benefit from pre-exposure prophylaxis (PrEP) including microbicides for HIV prevention. Since adherence is a key factor in PrEP efficacy, we explored microbicide acceptability and potential barriers to use within FSWs' intimate relationships in Tijuana and Ciudad Juárez, Mexico, where HIV prevalence is increasing. FSWs and their verified intimate (non-commercial) male partners completed quantitative and qualitative interviews from 2010 to 2012. Our complementary mixed methods design followed an iterative process to assess microbicide acceptability, explore related relationship dynamics and identify factors associated with concern about male partners' anger regarding microbicide use. Among 185 couples (n=370 individuals), interest in microbicides was high. In qualitative interviews with 28 couples, most participants were enthusiastic about microbicides for sex work contexts but some explained that microbicides could imply mistrust/infidelity within their intimate relationships. In the overall sample, nearly one in six participants (16%) worried that male partners would become angry about microbicides, which was associated with higher self-esteem among FSWs and lower self-esteem and past year conflicts causing injury within relationships among men. HIV prevention interventions should consider intimate relationship dynamics posing potential barriers to PrEP acceptability and adherence, involve male partners and promote risk communication skills.

The solution of the Schrodinger equation with physical potential is the important part in quantum physics. Many methods have been developed to resolve the Schrodinger equation. The Nikiforov-Uvarov method and supersymmetric method are the most methods that interesting to be explored. The supersymmetric method not only used to solve the Schrodinger equation but also used to construct the partner potential from a general potential. In this study, the Nikiforov-Uvarov method was used to solve the Schrodinger equation while the supersymmetric method was used to construction partner potential. The study about the construction of the partner potential from general potential Rosen-Morse and Manning Rosen in D-dimensional Schrodinger system has been done. The partner potential was obtained are solvable. By using the Nikiforov-Uvarov method the eigenfunction of the Schrodinger equation in D-dimensional system with general potential Rosen-Morse and Manning Rosen and the Schrodinger equation in D-dimensional system with partner potential Rosen-Morse and Manning Rosen are determined. The eigenfunctions are different between the Schrodinger equation with general potential and the Schrodinger potential with the partner potential.

This paper explores the intimate relationship experiences of the cisgender (i.e., not transgender) female partners of masculine-identifying transgender persons, with a particular focus on these partners' self-understanding of their sexual orientation. Limited research about this topic has been conducted to date. Semi-structured interviews were conducted with eight South African women who are or have been cisgender female partners of masculine-identifying trans persons. Although the interviews showed that the relationship experiences of female partners of masculine-identifying trans persons are diverse, several common themes emerged in the narratives. The way that participants labelled their sexual orientation did not change from before to after their relationship with a transgender partner. The participants reported varied family and community responses to their relationships. Specific emotional and informational support needs for women with transgender partners were identified.

In 2003, the Monterey County Health Department, serving Salinas, California, was awarded one of 12 grants from the Steps to a HealthierUS Program to implement a 5-year, multiple-intervention community approach to reduce diabetes, asthma, and obesity. National adult and youth surveys to assess long-term outcomes are required by all Steps sites; however, site-specific surveys to assess intermediate outcomes are not required. Salinas is a medically underserved community of primarily Mexican American residents with high obesity rates and other poor health outcomes. The health department's Steps program has partnered with traditional organizations such as schools, senior centers, clinics, and faith-based organizations as well as novel organizations such as employers of agricultural workers and owners of taquerias. The health department and the Stanford Prevention Research Center developed new site-specific, community-focused partner surveys to assess intermediate outcomes to augment the nationally mandated surveys. These site-specific surveys will evaluate changes in organizational practices, policies, or both following the socioecological model, specifically the Spectrum of Prevention. Our site-specific partner surveys helped to 1) identify promising new partners, select initial partners from neighborhoods with the greatest financial need, and identify potentially successful community approaches; and 2) provide data for evaluating intermediate outcomes matched to national long-term outcomes so that policy and organizational level changes could be assessed. These quantitative surveys also provide important context-specific qualitative data, identifying opportunities for strengthening community partnerships. Developing site-specific partner surveys in multisite intervention studies can provide important data to guide local program efforts and assess progress toward intermediate outcomes matched to long-term outcomes from nationally mandated surveys.

A cornerstone of sexually transmitted infection (STI) prevention is the identification, tracing, and notification of sex partners of index patients. Although partner notification reduces disease burden and prevents new infections as well as reinfections, studies show that only a limited number of partners are ever notified. Electronic communication technologies, namely, the Internet, text messaging, and phone calls (i.e., e-notification), have the potential to expand partner services. We conducted a systematic review of studies that have investigated the acceptability and utility of e-notification. We identified 23 studies that met the following criteria: (a) 9 studies presented data on the acceptability of technology-based communications for contacting sex partner(s), and (b) 14 studies reported on the utilization of communication technologies for partner notification. Studies found high levels of interest in and acceptability of e-notification; however, there was little evidence for actual use of e-notification. Taken together, results suggest that electronic communications could have their greatest impact in notifying less committed partners who would otherwise be uninformed of their STI exposure. In addition, all studies to date have been conducted in resource-rich countries, although the low cost of e-notification may have its greatest impact in resource-constrained settings. Research is needed to determine the best practices for exploiting the opportunities afforded by electronic communications for expanding STI partner services.

Partner dance has been shown to be beneficial for the health of older adults. Robots could potentially facilitate healthy aging by engaging older adults in partner dance-based exercise. However, partner dance involves physical contact between the dancers, and older adults would need to be accepting of partner dancing with a robot. Using methods from the technology acceptance literature, we conducted a study with 16 healthy older adults to investigate their acceptance of robots for partner dance-based exercise. Participants successfully led a human-scale wheeled robot with arms (i.e., a mobile manipulator) in a simple, which we refer to as the Partnered Stepping Task (PST). Participants led the robot by maintaining physical contact and applying forces to the robot's end effectors. According to questionnaires, participants were generally accepting of the robot for partner dance-based exercise, tending to perceive it as useful, easy to use, and enjoyable. Participants tended to perceive the robot as easier to use after performing the PST with it. Through a qualitative data analysis of structured interview data, we also identified facilitators and barriers to acceptance of robots for partner dance-based exercise. Throughout the study, our robot used admittance control to successfully dance with older adults, demonstrating the feasibility of this method. Overall, our results suggest that robots could successfully engage older adults in partner dance-based exercise.

Background An estimated 30% of HIV cases in the European Union are not aware of their serological status. This study aimed to assess the effectiveness of a pilot HIV partner notification program. Methods HIV cases diagnosed between January 2012 and June 2013 at two healthcare settings in Barcelona were invited to participate in a prospective survey. We identified process and outcome measures to evaluate this partner notification program, including the number of partners identified per interviewed index case, the proportion of partners tested for HIV as a result of the partner notification, and the proportion of new HIV diagnoses among their sex or needle-sharing partners. Results Of the 125 index cases contacted, 108 (86.4%) agreed to provide information about partners. A total of 199 sexual partners were identified (1.8 partners per interviewed index case). HIV outcome was already known for 58 partners (70.7% were known to be HIV-positive), 141 partners were tested as result of partner notification, and 26 were newly diagnosed with HIV. The case-finding effectiveness of the program was 18.4%. Conclusion This pilot program provides evidence of the effectiveness of a partner notification program implemented in healthcare settings. This active partner notification program was feasible, acceptable to the user, and identified a high proportion of HIV-infected patients previously unaware of their status. PMID:25849451

Of the 125 index cases contacted, 108 (86.4%) agreed to provide information about partners. A total of 199 sexual partners were identified (1.8 partners per interviewed index case). HIV outcome was already known for 58 partners (70.7% were known to be HIV-positive), 141 partners were tested as result of partner notification, and 26 were newly diagnosed with HIV. The case-finding effectiveness of the program was 18.4%. This pilot program provides evidence of the effectiveness of a partner notification program implemented in healthcare settings. This active partner notification program was feasible, acceptable to the user, and identified a high proportion of HIV-infected patients previously unaware of their status.

Effects of organophosphates on the regulation of mesenchymal stem cell proliferation and differentiation.

Mesenchymal stem cells (MSCs) are multipotent cells located within various adult tissues. Recent literature has reported that human bone marrow-derived MSCs express active acetylcholinesterase (AChE) and that disruption of AChE activity by organophosphate (OP) chemicals decreases the ability of MSCs to differentiate into osteoblasts. The potential role of AChE in regulating MSC proliferation and differentiation is currently unknown. In the present study, we demonstrate that MSCs exposed to OPs have both decreased AChE activity and abundance. In addition, exposure to these OPs induced cellular death while decreasing cellular proliferation. Exposures to these compounds also reduced the adipogenic/osteogenic differentiation potentials of the MSCs. To elucidate the possible role of AChE in MSCs signaling following OP exposure, we captured potential AChE binding partners by performing polyhistidine (His 8 )-tagged AChE pulldowns, followed by protein identification using liquid chromatography mass spectrometry (LC-MS). Using this method, we determined that the focal adhesion protein, vinculin, is a potential binding partner with AChE in MSCs and these initial findings were confirmed with follow-up co-immunoprecipitation experiments. Identifying AChE binding partners helps to determine potential pathways associated with MSC proliferation and differentiation, and this understanding could lead to the development of future MSC-based tissue repair therapies.

Song, Mia; He, Qianjing; Berk, Benjamin-Andreas

2016-01-15

Filamin A (FLNA) is an actin filament crosslinking protein with multiple intracellular binding partners. Mechanical force exposes cryptic FLNA binding sites for some of these ligands. To identify new force-dependent binding interactions, we used a fusion construct composed of two FLNA domains, one of which was previously identified as containing a force-dependent binding site as a bait in a yeast two-hybrid system and identified the Rho dissociation inhibitor 2 (RhoGDI2) as a potential interacting partner. A RhoGDI2 truncate with 81 N-terminal amino acid residues and a phosphomimetic mutant, RhoGDI(Tyr153Glu) interacted with the FLNA construct. However, neither wild-type or full-length RhoGDI2 phosphorylatedmore » at Y153 interacted with FLNA. Our interpretation of these contradictions is that truncation and/or mutation of RhoGDI2 perturbs its conformation to expose a site that adventitiously binds FLNA and is not a bona–fide interaction. Therefore, previous studies reporting that a RhoGDI(Y153E) mutant suppresses the metastasis of human bladder cancer cells must be reinvestigated in light of artificial interaction of this point mutant with FLNA. - Highlights: • RhoGDI2 is identified as a potential filamin A (FLNA)-binding partner. • Phosphomimetic mutant, RhoGDI2(Tyr153Glu) interacts with FLNA. • RhoGDI2 phosphorylated (Tyr153) by src kinase does not interact with FLNA. • Mutation of Tyr-153 to Glu of RhoGDI2 does not mimic phosphorylation. • RhoGDI2(Tyr153Glu) provokes an adventitious interaction with FLNA.« less

Husband's/partner's support for family planning may influence a women's modern contraceptive use. Socio-demographic factors, couple communication about family planning, and fertility preferences are known to play a role in contraceptive use. We conducted logistic regression analysis to investigate the relationship between perceived husband's/partner's approval and husband's/partner's encouragement of modern contraceptive use, adjusting for socio-demographic factors and recent couple communication about family planning. We also examined mediating roles potentially played by perceived contraceptive accessibility and contraceptive self-efficacy (using index created by principal component analysis). Perceived husband's/partner's approval was associated with triple the odds of women's modern contraceptive use and remained significantly associated with 1.6 times the odds, after controlling for contraceptive accessibility and contraceptive self-efficacy. Husband's/partner's encouragement, while initially significantly associated with contraceptive use, became non-significant after adjustments for socio-demographic factors and couple communication. Perceived husband's/partner's approval, separate from a woman's sense of self-efficacy and perceived accessibility of contraceptives, appears strongly and positively associated with current modern contraceptive use. Increased couple communication may help women identify their husband's/partner's approval. Difference between the meaning of approval and encouragement should be explored. Interventions involving information education and communication campaigns geared to men and promoting male involvement in family planning could increase contraceptive prevalence.

Patterns in PARTNERing across Public Health Collaboratives.

Inter-organizational networks represent one of the most promising practice-based approaches in public health as a way to attain resources, share knowledge, and, in turn, improve population health outcomes. However, the interdependencies and effectiveness related to the structure, management, and costs of these networks represents a critical item to be addressed. The objective of this research is to identify and determine the extent to which potential partnering patterns influence the structure of collaborative networks. This study examines data collected by PARTNER, specifically public health networks (n = 162), to better understand the structured relationships and interactions among public health organizations and their partners, in relation to collaborative activities. Combined with descriptive analysis, we focus on the composition of public health collaboratives in a series of Exponential Random Graph (ERG) models to examine the partnerships between different organization types to identify the attribute-based effects promoting the formation of network ties within and across collaboratives. We found high variation within and between these collaboratives including composition, diversity, and interactions. The findings of this research suggest common and frequent types of partnerships, as well as opportunities to develop new collaborations. The result of this analysis offer additional evidence to inform and strengthen public health practice partnerships.

Participatory research aims to increase the relevance and broaden the implementation of health research by involving those affected by the outcomes of health studies. Few studies within the field of neurodevelopmental disorders, particularly autism spectrum disorders, have involved autistic individuals as partners. This study sought to identify and characterize published participatory research partnerships between researchers and individuals with autism spectrum disorder or other neurodevelopmental disorders and examine the influence of participatory research partnerships on the research process and reported study outcomes. A search of databases and review of gray literature identified seven studies that described participatory research partnerships between academic researchers and individuals with autism spectrum disorder or other neurodevelopmental disorders. A comparative analysis of the studies revealed two key themes: (1) variations in the participatory research design and (2) limitations during the reporting of the depth of the partner's involvement. Both themes potentially limit the application and generalizability of the findings. The results of the review are discussed in relation to the use of evaluative frameworks for such participatory research studies to determine the potential benefits of participatory research partnerships within the neurodevelopmental and autism spectrum disorder populations. © The Author(s) 2014.

Self-Presentation, Desired Partner Characteristics, and Sexual Behavior Preferences in Online Personal Advertisements of Men Seeking Non-Gay-Identified Men.

Downing, Martin J; Schrimshaw, Eric W

2014-03-14

Despite attention to the sexual behaviors of non-gay-identified (NGI) men who have same-sex encounters, virtually no research has focused on issues of partner desirability and selection. Limited evidence suggests that a subgroup of men who have sex with men (MSM) advertise online for sexual encounters with NGI men. Exchange theory provided a framework to investigate this seeking of NGI men, based on the content of Internet personal advertisements for same-sex encounters. Researchers analyzed 282 ads posted to an online bulletin board. Ads by men who explicitly desired encounters with NGI men were compared with those by men who did not indicate this preference in potential partners. Multivariate analyses revealed that NGI-seeking men had significantly increased odds of identifying as discreet (Adjusted odds ratio [ AOR ] = 2.82), seeking a discreet encounter ( AOR = 4.68), seeking a masculine partner ( AOR = 2.18), being willing to host ( AOR = 2.77), as well as seeking oral-receptive sex ( AOR = 2.69), unprotected oral sex ( AOR = 6.76), and anal-receptive sex ( AOR = 2.18). Further, NGI-seeking ads were more likely to not mention condom use or safer sex practices ( AOR = 4.13) and were less likely to indicate a desire for oral-insertive sex ( AOR = 0.34) and rimming ( AOR = 0.21). Findings suggest that some men may deliberately present themselves in ways that they perceive as being attractive to NGI men, and have research implications for NGI MSM, their partners, and the risk outcomes of these online ads.

Summary Aim The rates of HIV acquired through heterosexual contact are increasing in the Czech Republic. This study explored potential HIV risk associations with alcohol, illicit drugs and sexual behaviours among adults from a community-based sample attending gay- and non-gay venues in Prague. Methods Women attending bars, cafes and beer gardens in central Prague responded to the self-administered, time-site survey. Alcohol use was measured by the AUDIT-C and CAGE questionnaires. Sexual network structuring identified number, gender and coital frequency with current and recent sexual partners. Statistical analysis included central tendency, chi-square and logistic regression. Female participants (n = 124) ranged from 18 to 67 years of age (mean 29 years); 25% self-identified as non-heterosexual. Results We found alcohol to be the preferred drug of choice. Younger heterosexual women with new and casual sexual partners were more likely to use alcohol excessively. Women with children reported the least alcohol use. Sixty percent of the sample had never used condoms; condom-use was associated with longer relationship duration and discussions about HIV status with a sexual partner; non-use tended to occur among unmarried women with multiple male partners in short, serial sexual relationships. Women who sought HIV testing tended to be younger and more self-identified as non-heterosexual. Protective practices were rarely reported even when HIV transmission increases via heterosexual sexual partnering. Conclusion Further research is recommended regarding cultural and contextual influences on HIV risk behaviours among Czech women. PMID:26851424

Online surveys of patients and caregivers managing rare (n = 560 patients, n = 609 caregivers) or chronic conditions (n = 762 patients, n = 776 caregivers) and practicing clinicians (n = 638). Over half of respondents were unfamiliar with the concept of partnering with researchers but most expressed interest in working in a research partnership. Potential facilitators endorsed were ensuring research is meaningful, applying results in an understandable way, and sharing results. Lack of time is a potential barrier. Clinicians were most interested in helping researchers decide on intervention comparisons and identifying implications for clinical practice. Patients, caregivers and clinicians are interested in research roles that emphasize usefulness and understandability of research.

This study explores the intimate relationship experiences of cisgender (i.e., not transgender) female partners of masculine identifying transgender persons, with a particular focus on these partners’ self-understanding of their sexual orientation. Limited research about this topic has been conducted to date. Semi-structured interviews were conducted with eight South African women who are or have been cisgender female partners of masculine identifying trans persons. Although the interviews showed that the relationship experiences of female partners of masculine identifying trans persons are diverse, several common themes emerged in the narratives. The way that participants labelled their sexual orientation did not change from before to after their relationship with a transgender partner. The participants reported varied family and community responses to their relationships. Specific emotional and informational support needs for women with transgender partners were identified.

Interactions between structured proteins require a complementary topology and surface chemistry to form sufficient contacts for stable binding. However, approximately one third of protein interactions are estimated to involve intrinsically disordered regions of proteins. The dynamic nature of disordered regions before and, in some cases, after binding calls into question the role of partner topology in forming protein interactions. To understand how intrinsically disordered proteins identify the correct interacting partner proteins, we evaluated interactions formed by the Drosophila melanogaster Hox transcription factor Ultrabithorax (Ubx), which contains both structured and disordered regions. Ubx binding proteins are enriched in specific folds: 23 of its 39 partners include one of 7 folds, out of the 1195 folds recognized by SCOP. For the proteins harboring the two most populated folds, DNA-RNA binding 3-helical bundles and α-α superhelices, the regions of the partner proteins that exhibit these preferred folds are sufficient for Ubx binding. Three disorder-containing regions in Ubx are required to bind these partners. These regions are either alternatively spliced or multiply phosphorylated, providing a mechanism for cellular processes to regulate Ubx-partner interactions. Indeed, partner topology correlates with the ability of individual partner proteins to bind Ubx spliceoforms. Partners bind different disordered regions within Ubx to varying extents, creating the potential for competition between partners and cooperative binding by partners. The ability of partners to bind regions of Ubx that activate transcription and regulate DNA binding provides a mechanism for partners to modulate transcription regulation by Ubx, and suggests that one role of disorder in Ubx is to coordinate multiple molecular functions in response to tissue-specific cues.

Potential advantages and disadvantages of dual-career relationships are identified, and strategies for addressing common issues encountered by dual-career couples are presented. With regard to career issues, clarification of expectations and discussion between partners regarding career commitment, job selection and mobility, and maintenance of professional identity is emphasized. Benefits of dual-career relationships include shared occupational interests, financial rewards, and respect for each partner's professional expertise. Strategies for managing domestic responsibilities include modifying standards, setting priorities, and distributing tasks evenly among family members. Pharmacist couples who are parents have chosen several routes in managing child-care issues, including postponing childbearing until each adult's career is established, decreasing one partner's career involvement, and hiring community or in-home caretakers. Sharing equally in child care can help prevent an excessive workload for one parent. Progressive family-oriented employment practices may also aid dual-career couples with children. Striking a balance between career and family is identified as perhaps the most challenging task facing the dual-career couple; time distribution must be adjusted according to the couple's priorities. Identifying realistic priorities, negotiating honestly regarding attainment of mutual and individual goals, and maintaining flexibility are key in achieving success in the professional and private lives of two-pharmacist couples.

Parent-child conflict in the context of a supportive relationship has been discussed as a potentially constructive interaction pattern; the current study is the first to test this using a holistic analytic approach. Interaction styles, defined as mother-child conflict in the context of maternal sensitivity, were identified and described with demographic and stress-related characteristics of families. Longitudinal associations were tested between interaction styles and children's later social competence. Participants included 814 partnered mothers with a first-grade child. Latent profile analysis identified agreeable , dynamic , and disconnected interaction styles. Mothers' intimacy with a partner, depressive symptoms, and authoritarian childrearing beliefs, along with children's later conflict with a best friend and externalizing problems, were associated with group membership. Notably, the dynamic style, characterized by high sensitivity and high conflict, included families who experienced psychological and relational stressors. Findings are discussed with regard to how family stressors shape parent-child interaction patterns.

To study the prevalence of partner violence, and to identify the associated risk factors in a sample of female workers of IMSS (Mexican Social Security Institute), Morelos State. Cross-sectional data from 1 173 women participating in the cohort study of IMSS workers are utilized to study these associations. The study provides information on frequency of psychological, physical or sexual violence and perception of severity during the 12 months prior to the time of data collection. It was carried out in Morelos between October 1998 and March 2000. Polytomous logistic regression models were used to obtain odds ratios for different degrees of partner violence. A high prevalence of partner violence is observed in the sample. Main factors associated with higher severity of violence are state of the relationship and alcohol intake, emotional status of the couple at home, work burden of the woman, and a history of violence in childhood. All these factors are potentially modifiable through interventions aimed at stress reduction. These results should be considered when developing preventive programs against partner violence in Mexico.

This article presents an innovative model for interprofessional community-oriented learning. The Engagement Studios model involves a partnership between community organizations and students as equal partners in conversations and activities aimed at addressing issues of common concern as they relate to the social determinants of health. Interprofessional teams of students from health and non-health disciplines work with community partners to identify priority community issues and explore potential solutions. The student teams work with a particular community organization, combining their unique disciplinary perspectives to develop a project proposal, which addresses the community issues that have been jointly identified. Approved proposals receive a small budget to implement the project. In this paper we present the Engagement Studios model and share lessons learned from a pilot of this educational initiative.

Employee Assistance Programs (EAPs) are workplace resources available to employees with problems impacting work performance. EAPs are well-positioned to address intimate partner violence (IPV), a major public health problem with workplace impacts. A purposeful sample of 28 EAPs across the United States was surveyed to identify policies and programs to address IPV, including perpetration. Most EAPs did not report having standardized approaches for addressing IPV perpetration. EAPs also described significant barriers to identifying IPV perpetrators, with the majority relying on self-disclosure on the part of the perpetrator when contacting the EAP. These results suggest that many EAPs--even when interacting with employees who present with issues known to correlate with IPV--are missing a potential opportunity to assess and intervene with IPV perpetrators.

Identifying individual residues in the interfaces of protein-RNA complexes is important for understanding the molecular determinants of protein-RNA recognition and has many potential applications. Recent technical advances have led to several high-throughput experimental methods for identifying partners in protein-RNA complexes, but determining RNA-binding residues in proteins is still expensive and time-consuming. This chapter focuses on available computational methods for identifying which amino acids in an RNA-binding protein participate directly in contacting RNA. Step-by-step protocols for using three different web-based servers to predict RNA-binding residues are described. In addition, currently available web servers and software tools for predicting RNA-binding sites, as well as databases that contain valuable information about known protein-RNA complexes, RNA-binding motifs in proteins, and protein-binding recognition sites in RNA are provided. We emphasize sequence-based methods that can reliably identify interfacial residues without the requirement for structural information regarding either the RNA-binding protein or its RNA partner.

The Food and Drug Administration's Sentinel System developed parameterized, reusable analytic programs for evaluation of medical product safety. Research on outpatient antibiotic exposures, and Clostridium difficile infection (CDI) with non-user reference groups led us to expect a higher rate of CDI among outpatient clindamycin users vs penicillin users. We evaluated the ability of the Cohort Identification and Descriptive Analysis and Propensity Score Matching tools to identify a higher rate of CDI among clindamycin users. We matched new users of outpatient dispensings of oral clindamycin or penicillin from 13 Data Partners 1:1 on propensity score and followed them for up to 60 days for development of CDI. We used Cox proportional hazards regression stratified by Data Partner and matched pair to compare CDI incidence. Propensity score models at 3 Data Partners had convergence warnings and a limited range of predicted values. We excluded these Data Partners despite adequate covariate balance after matching. From the 10 Data Partners where these models converged without warnings, we identified 807 919 new clindamycin users and 8 815 441 new penicillin users eligible for the analysis. The stratified analysis of 807 769 matched pairs included 840 events among clindamycin users and 290 among penicillin users (hazard ratio 2.90, 95% confidence interval 2.53, 3.31). This evaluation produced an expected result and identified several potential enhancements to the Propensity Score Matching tool. This study has important limitations. CDI risk may have been related to factors other than the inherent properties of the drugs, such as duration of use or subsequent exposures. Copyright © 2018 John Wiley & Sons, Ltd.

Erectile dysfunction (ED) is a prevalent condition that impacts on both patients and their female partners. ED may therefore be regarded as a shared sexual concern for couples. The current analysis of the Female Experience of Men's Attitudes to Life Events and Sexuality (FEMALES) study data addresses women's perceptions, beliefs, and attitudes concerning their partner's ED, and whether these are associated with the likelihood of the male partner seeking medical advice and utilizing phosphodiesterase type 5 inhibitors. The current research sought to explore the association of female partners' perceptions of male partners' ED and male partners' medical consultation and treatment seeking for ED. Questionnaires were sent to partners of men who participated in the Men's Attitudes to Life Events and Sexuality (MALES) 2004 study, and who consented to their partner's involvement. A modified version of the questionnaire used in the MALES study was developed for the FEMALES study, reflecting the female partner's perspective. A 65-item questionnaire assessing women's perceptions, beliefs, and attitudes regarding various aspects of ED. Women's perceptions of the nature and causes of their partner's ED were significantly associated with men's treatment seeking and utilization. Significant associations were observed between women's level of satisfaction with the relationship before ED onset; perceptions of the impact of ED on quality of life; desire to deal with ED; attitudes to ED treatment; and the treatment-seeking behavior of the male partner. Multivariate regression analyses identified a mixture of female and male partner perceptions and attitudes that uniquely accounted for >30% of the variance in men's ED treatment-seeking behavior and treatment utilization. This study illustrates the importance of the female partner's attitudes to ED in men's ED treatment-seeking behavior. These findings strongly support the potential benefits of partner integration into ED consultation and treatment strategies.

HIV risk practices sought by men who have sex with other men, and who use internet websites to identify potential sexual partners.

2008-09-01

Men who have sex with men (MSM) account for the largest number of persons diagnosed with AIDS in the USA, with higher than average rates of drug use and unprotected sex being cited as the principal reasons underlying their high rates of HIV infection. Recent evidence has suggested that the use of websites specifically designed to promote unsafe sexual practices may be particularly common among MSM, thereby fostering their risky behaviours. In light of these findings, the present study is based on a content analysis of 1316 ads/profiles posted on one of the most popular MSM websites that specifically fosters unprotected sex. Ads/profiles were selected randomly based on the American ZIP code of residence. Data were collected between September 2006 and January 2007. Rates of advertised for high-risk sexual behaviours were very high, particularly for oral sex involving ejaculation into the mouth (88.0% for receptive oral sex, 77.4% for insertive oral sex), anal sex involving ejaculation into the anus (79.7% for insertive anal sex, 69.4% for receptive anal sex), multiple partner sex (77.9%) and felching (16.5%). A multivariate analysis of the correlates of sexual risk preferences identified seven factors that were related to a propensity towards enhanced sexual risk: younger age (beta = 0.12, P = 0.0001), not being African American (beta = 0.05, P = 0.0341), self-identification as a sexual 'bottom' (beta = 0.20, P = 0.0001), not caring about one's potential sex partners' HIV serostatus (beta = 0.15, P = 0.0001), preferring to have sex while under the influence of drugs (beta = 0.08, P = 0.0022), a greater involvement in and commitment to the use of the website to locate potential unprotected sex partners (beta = 0.16, P = 0.0001) and not being HIV-negative (beta = 0.08, P = 0.0081). The HIV intervention-related implications of these findings are discussed.

Physicians play a significant role in screening for domestic violence. However, little information is available about the prevalence of physicians who experience intimate partner violence (IPV) or the implications for their clinical practice. National surveys indicate a potential prevalence of 16% for sexual abuse and 32% for abuse by an intimate partner. This extrapolates to more than 395,000 potential physician victims, the majority of which are women. We conducted a systematic review of IPV and physician victims from 1990 to 2014 that included peer-reviewed journals, trade books, and dissertations that referenced physician victims. We identified 17 publications; nine quantitative studies, four first-person accounts, one qualitative study, and a qualitative dissertation that included two physician subjects. Two case studies of victimized physicians were identified in trade books. Quantitative results noted that women reported higher prevalence for all experiences of violence [childhood exposure (6%-32%), adult IPV exposure (7%-24%)] than men (6%-10%). This review highlights the need for improved understanding of physician experience with IPV, and development of physician-sensitive resources and treatment approaches. Contributions and limitations are provided for each publication. IPV exposure impacts clinical practice, including reticence to consistently screen patients. Lower reported prevalence may be related to extreme stigma among physicians that may prevent their reporting and help seeking, but more research is needed. We provide recommendations for clinical practice, education, and future research.

In the brain, the Homer protein family modulates excitatory signal transduction and receptor plasticity through interactions with other proteins in dendritic spines. Homer proteins are implicated in a variety of psychiatric disorders such as schizophrenia and addiction. Since long Homers serve as scaffolding proteins, identifying their interacting partners is an important first step in understanding their biological function and could help to guide the design of new therapeutic strategies. The present study set out to document Homer2-interacting proteins in the mouse brain using a co-immunoprecipitation-based mass spectrometry approach where Homer2 knockout samples were used to filter out non-specific interactors. We found that in the mouse brain, Homer2 interacts with a limited subset of its previously reported interacting partners (3 out of 31). Importantly, we detected an additional 15 novel Homer2-interacting proteins, most of which are part of the N-methyl-D-aspartate receptor signaling pathway. These results corroborate the central role Homer2 plays in glutamatergic transmission and expand the network of proteins potentially contributing to the behavioral abnormalities associated with altered Homer2 expression. Long Homer proteins are scaffolding proteins that regulate signal transduction in neurons. Identifying their interacting partners is key to understanding their function. We used co-immunoprecipitation in combination with mass spectrometry to establish the first comprehensive list of Homer2-interacting partners in the mouse brain. The specificity of interactions was evaluated using Homer2 knockout brain tissue as a negative control. The set of proteins that we identified minimally overlaps with previously reported interacting partners of Homer2; however, we identified novel interactors that are part of a signaling cascade activated by glutamatergic transmission, which improves our mechanistic understanding of the role of Homer2 in behavior.

In 2008, we conducted online interviews with 65 self-identified adult heterosexual men and women and gay/bisexual men to explore perceptions and experiences with meeting people online. Reasons for meeting people online, desired partner characteristics, and the process of connecting for sex paralleled those observed in real-life; but the Internet allowed people to identify more partners and specific partner characteristics. “Background checks” of online partners, even though often believed to be false, increased familiarity and trust leading to reduced perceived need for condom use. Participants said online condom use negotiation was easier, but usually occurred in face-to-face contexts in practice. (99) PMID:25767648

To identify and synthesise the needs of care partners of older people living at home with assistance from home care services. "Ageing in place" is a promoted concept where care partners and home care services play significant roles. Identifying the needs of care partners and finding systematic ways of meeting them can help care partners to cope with their role. This study is based on the PRISMA reporting guidelines. The systematic review of qualitative and quantitative studies was guided by the Joanna Briggs Institute methodology. In total, 16 studies were included in the review, eleven qualitative and five quantitative. Three main categories were revealed in the analysis: the need for quality interaction, the need for a shared approach to care and the need to feel empowered. Care partners of older people have several, continuously unmet needs. A person-centred perspective can contribute new understandings of how to meet these needs. A knowledge gap has been identified regarding the needs of care partners of older people with mental health problems. There is a need to develop a tool for systematic collaboration between home care services and care partners, so that the identified needs can be met in a more thorough, systematic and person-centred way. The carers in home care services need competence to identify and meet the needs of care partners. The implementation of person-centred values in home care services can contribute to meet the needs of care partners to a greater extent than today. Future research on the needs of care partners of older people with mental health problems needs to be undertaken. © 2017 John Wiley & Sons Ltd.

Male partner selectivity, romantic confidence, and media depictions of partner scarcity.

PubMed

Taylor, Laramie D

2013-01-18

An experiment was conducted to explore the effects of exposure to partner scarcity or abundance messages on men's partner selectivity, romantic confidence, and self-assessed attractiveness. Undergraduate male participants watched a soap opera narrative featuring either two men competing over one potential female partner (partner scarcity) or two women competing over one potential male partner (partner abundance). Relative to control subjects, watching either narrative reduced romantic confidence. Experimental condition also affected partner selectivity and self-assessed attractiveness, though both effects were moderated by endorsement of traditional masculine ideology. Viewing the abundance narrative resulted in greater selectivity and self-assessed attractiveness for men high in endorsement of traditional masculinity but diminished selectivity and self-assessed attractiveness for men low in endorsement of traditional masculine identity.

The epidemic of HIV/AIDS among Chinese men who have sex with men (MSM) is rapidly escalating. We implemented partner notification among HIV-infected MSM, cooperating with MSM-serving community-based organizations (CBOs) in two Chinese cities from June 2014 to May 2015. CBOs participated in identifying new HIV-positive MSM utilizing rapid HIV tests and partner notification among index cases. 253 index cases were recruited and 275 sexual partners were notified and tested with 10.5% screened positive. Compared with previously identified index cases, the proportion of contactable sexual partners of newly identified index cases was higher, but the testing rate was lower (p < 0.001). Overall, 83.7% of sexual partners were casual with a contactable rate of 24.9% and a HIV testing rate of 71.1%. Having no contact information for sexual partners and fear of disclosure of HIV status are the main reasons for declining partner notification. It is feasible and effective to perform partner notification in cooperation with CBOs serving Chinese MSM. © The Author(s) 2016.

Depression is known to mediate the association between low social support and parenting competence in adult mothers, but this relationship is rarely assessed in adolescent mothers and fathers. The primary aim of this study was to identify the association between social support, family functioning and social capital on parenting competence, including self-efficacy and satisfaction in adolescent mothers and their partners. Secondary aims included identifying potential partner effects (e.g. whether a partner's social support influenced the respondent's parenting efficacy). Data was obtained from a subset of participants from a longitudinal study of pregnant adolescent females and their partners. Couples completed individual structured interviews via audio computer-assisted self-interview during pregnancy and at 6 months postpartum. To measure the influence of support on parenting outcomes, multi-level modeling was used to assess the Actor-Partner Interdependence model, which examines responses from both members of a dyad in a single analysis. Greater social support was associated with increased parenting self-efficacy (B = 0.062, p = 0.006) and parenting satisfaction (B = 0.111, p < 0.001). Higher family functioning was also associated with greater parenting satisfaction (B = 0.05, p = 0.035). Greater partner family functioning was associated with higher parenting satisfaction (B = 0.047, p = 0.026). This study found the importance of a strong support structure during pregnancy on perceived parenting competence in the early postpartum period for young mothers and fathers. Both social support and family functioning during pregnancy were associated with a greater sense of parenting competence, and these associations were mediated by parental depression. The results of this study underscore the importance of providing social support for young expectant fathers as well as mothers.

A typological approach to testing the evolutionary functions of human female orgasm.

King, Robert; Belsky, Jay

2012-10-01

Building on previous work that identified different types of orgasm in women (King, Belsky, Mah, & Binik, 2011), the goal of the present study was to extend such typological work and determine whether female orgasmic variability tracked potentially evolutionarily salient sexual partner characteristics (e.g., those displaying possible immune-system compatibility). A total of 265 females completed an Internet survey about their orgasmic experience-achieved either with partners or alone. For partnered orgasms, they also provided details of partner characteristics and sexual behaviors. Latent class analysis revealed two orgasm types which were meaningfully distinguishable in terms of sensations and location-either centered on the surface of genitalia or deep inside. Deep orgasms were associated with internal sensations consistent with proposed functions of female orgasm in terms of differential sperm insuck. Such orgasms were associated with partners who were perceived as considerate, dominant, with a noticeably attractive smell, and as providing firm penetration. However, some hypothesized reproductively significant partner characteristics were not differentially associated with deep orgasms (i.e., muscularity, aggression, masculinity). Results were discussed and future research directions outlined. In particular, it is suggested that sexual passion between partners is a non-accidental component of sexual functioning and that this has too frequently been missing in sex research involving humans. Direct physiological measures of the results of female orgasm need to be undertaken. Additionally, the intriguing phenomenon of female ejaculation deserves scientific attention.

Introduction. Violence against women has serious consequences for their reproductive and sexual health including birth outcomes. In Ethiopia, though the average parity of pregnant women is much higher than in other African countries, the link between intimate partner violence with low birth weight is unknown. Objective. The aim of this study was to examine the association between intimate partner violence and low birth weight among pregnant women. Method. Hospital based case-control study was conducted among 387 mothers (129 cases and 258 controls). Anthropometric measurements were taken both from mothers and their live births. The association between intimate partner violence and birth weight was computed through bivariable and multivariable logistic regression analyses and statistical significance was declared at P < 0.05. Result. Out of 387 interviewed mothers, 100 (25.8%) had experienced intimate partner violence during their index pregnancy period. Relatively more mothers of low birth weight infants were abused (48%) compared with controls (16.4%). Those mothers who suffered acts of any type of intimate partner violence during pregnancy were three times more likely to have a newborn with low birth weight (95% CI; (1.57 to 7.18)). The association between overall intimate partner violence and LBW was adjusted for potential confounder variables. Conclusion. This research result gives insight for health professional about the importance of screening for intimate partner violence during pregnancy. Health care providers should consider violence in their practice and try to identify women at risk. PMID:26798345

Marital Processes Linking Gender Role Attitudes and Marital Satisfaction Among Mexican-Origin Couples: Application of an Actor-Partner Interdependence Mediation Model.

2018-01-24

Informed by dyadic approaches and culturally informed, ecological perspectives of marriage, we applied an actor-partner interdependence mediation model (APIMeM) in a sample of 120 Mexican-origin couples to examine (a) the associations linking Mexican immigrant husbands' and wives' gender role attitudes to marital satisfaction directly and indirectly through marital processes (i.e., warmth and negativity) and (b) whether the associations between spouses' gender role attitudes and marital processes were moderated by wives' employment. Although previous research has identified spouses' gender role attitudes as potential predictors of spouses' marital satisfaction, no study has examined these links in a dyadic model that elucidates how gender role attitudes may operate through processes to shape marital satisfaction and conditions under which associations may differ. We found that when spouses reported less sex-typed attitudes, their partners reported feeling more connected to them and more satisfied with the marriage, regardless of whether wives were employed. Our results suggest that marital satisfaction was highest for those Mexican-origin couples in which marital partners were less sex-typed in their attitudes about marital roles to the extent that partners' attitudinal role flexibility promoted spouses' feelings of warmth and connection to their partner. © 2018 Family Process Institute.

Partner symmetries of the complex Monge Ampère equation yield hyper-Kähler metrics without continuous symmetries

We extend the Mason-Newman Lax pair for the elliptic complex Monge-Ampère equation so that this equation itself emerges as an algebraic consequence. We regard the function in the extended Lax equations as a complex potential. Their differential compatibility condition coincides with the determining equation for the symmetries of the complex Monge-Ampère equation. We shall identify the real and imaginary parts of the potential, which we call partner symmetries, with the translational and dilatational symmetry characteristics, respectively. Then we choose the dilatational symmetry characteristic as the new unknown replacing the Kähler potential. This directly leads to a Legendre transformation. Studying the integrability conditions of the Legendre-transformed system we arrive at a set of linear equations satisfied by a single real potential. This enables us to construct non-invariant solutions of the Legendre transform of the complex Monge-Ampère equation. Using these solutions we obtained explicit Legendre-transformed hyper-Kähler metrics with a anti-self-dual Riemann curvature 2-form that admit no Killing vectors. They satisfy the Einstein field equations with Euclidean signature. We give the detailed derivation of the solution announced earlier and present a new solution with an added parameter. We compare our method of partner symmetries for finding non-invariant solutions to that of Dunajski and Mason who use 'hidden' symmetries for the same purpose.

Climate change adaptation benefits of potential conservation partnerships.

Monahan, William B; Theobald, David M

2018-01-01

We evaluate the world terrestrial network of protected areas (PAs) for its partnership potential in responding to climate change. That is, if a PA engaged in collaborative, trans-boundary management of species, by investing in conservation partnerships with neighboring areas, what climate change adaptation benefits might accrue? We consider core tenets of conservation biology related to protecting large areas with high environmental heterogeneity and low climate change velocity and ask how a series of biodiversity adaptation indicators change across spatial scales encompassing potential PA and non-PA partners. Less than 1% of current world terrestrial PAs equal or exceed the size of established and successful conservation partnerships. Partnering at this scale would increase the biodiversity adaptation indicators by factors up to two orders of magnitude, compared to a null model in which each PA is isolated. Most partnership area surrounding PAs is comprised of non-PAs (70%), indicating the importance of looking beyond the current network of PAs when promoting climate change adaptation. Given monumental challenges with PA-based species conservation in the face of climate change, partnerships provide a logical and achievable strategy for helping areas adapt. Our findings identify where strategic partnering efforts in highly vulnerable areas of the world may prove critical in safeguarding biodiversity.

Accessing, assessing, exchanging, and applying dementia care information can be challenging in rural communities for healthcare practitioners (HCPs), persons with dementia (PWD), and their care partners. The overall purpose of this research was to enable HCPs, care partners, and PWD to use dementia care information more effectively by examining their information needs, how these change over time, and how they access, assess, and apply the knowledge. A qualitative interpretive descriptive approach was used. A convenience sample was initially recruited through study collaborators in Southwestern Ontario, followed by purposive sampling. Nine rural dementia care networks consisting of PWD (n = 5), care partners (n = 14), and HCPs (n = 14) were recruited and 80 interviews were conducted at three time points. Transcripts were coded using Lubrosky's thematic analysis. Six stages of the dementia care journey were identified: (1) recognizing the symptoms; (2) receiving a diagnosis; (3) loss of independence; (4) initiating and using home care and respite services; (5) long-term care (LTC) placement; and (6) decisions related to end-of-life care. Rural care partners identified the need for different types of knowledge during each of these critical decision points of the dementia care journey. They accessed information from family members, friends, local organizations, and dementia internet sites. Persons with dementia tended not to identify the need for dementia care information. The HCPs accessed dementia care information from their own organization, other organizations, and internet sites. Care partners and HCPs assessed the trustworthiness of the information based on whether the source was a well-known agency or their own organization. Barriers to knowledge exchange included: lack of rural community-based services for dementia care; care partners reluctant to seek help and had limited energy; and lack of integration of dementia-related services and supports. Facilitators of knowledge exchange included: rural care partners with healthcare experience who were actively seeking information; development of trusting relationships between HCPs, care partners, and PWD; and formal mechanisms for exchanging information within and across rural community-based organizations. This research illustrates the stages of the dementia care journey, and the types of information typically needed, accessed, assessed, and applied at each stage. Healthcare practitioners can use these findings to support rural care partners in navigating their dementia care journey. Support is needed as care partners often do not have the time, energy, skills, or knowledge to seek out dementia care information independently. In addition, PWD typically do not recognize the need for this knowledge, leaving care partners potentially isolated in this journey. Developing formal linkages within and across rural organizations will facilitate knowledge exchange and the delivery of cost-effective, quality dementia care. However, additional rural community-based resources are urgently needed to implement these recommendations. This may require a redistribution of resources from acute care to rural community care.

A conserved juxtacrine signal regulates synaptic partner recognition in Caenorhabditis elegans

PubMed Central

2011-01-01

Background An essential stage of neural development involves the assembly of neural circuits via formation of inter-neuronal connections. Early steps in neural circuit formation, including cell migration, axon guidance, and the localization of synaptic components, are well described. However, upon reaching their target region, most neurites still contact many potential partners. In order to assemble functional circuits, it is critical that within this group of cells, neurons identify and form connections only with their appropriate partners, a process we call synaptic partner recognition (SPR). To understand how SPR is mediated, we previously developed a genetically encoded fluorescent trans-synaptic marker called NLG-1 GRASP, which labels synaptic contacts between individual neurons of interest in dense cellular environments in the genetic model organism Caenorhabditis elegans. Results Here, we describe the first use of NLG-1 GRASP technology, to identify SPR genes that function in this critical process. The NLG-1 GRASP system allows us to assess synaptogenesis between PHB sensory neurons and AVA interneurons instantly in live animals, making genetic analysis feasible. Additionally, we employ a behavioral assay to specifically test PHB sensory circuit function. Utilizing this approach, we reveal a new role for the secreted UNC-6/Netrin ligand and its transmembrane receptor UNC-40/Deleted in colorectal cancer (DCC) in SPR. Synapses between PHB and AVA are severely reduced in unc-6 and unc-40 animals despite normal axon guidance and subcellular localization of synaptic components. Additionally, behavioral defects indicate a complete disruption of PHB circuit function in unc-40 mutants. Our data indicate that UNC-40 and UNC-6 function in PHB and AVA, respectively, to specify SPR. Strikingly, overexpression of UNC-6 in postsynaptic neurons is sufficient to promote increased PHB-AVA synaptogenesis and to potentiate the behavioral response beyond wild-type levels. Furthermore, an artificially membrane-tethered UNC-6 expressed in the postsynaptic neurons promotes SPR, consistent with a short-range signal between adjacent synaptic partners. Conclusions These results indicate that the conserved UNC-6/Netrin-UNC-40/DCC ligand-receptor pair has a previously unknown function, acting in a juxtacrine manner to specify recognition of individual postsynaptic neurons. Furthermore, they illustrate the potential of this new approach, combining NLG-1 GRASP and behavioral analysis, in gene discovery and characterization. PMID:21663630

Background Female sex workers (FSWs) may benefit from pre-exposure prophylaxis (PrEP) including microbicides for HIV prevention. Since adherence is a key factor in PrEP efficacy, we explored microbicide acceptability and potential barriers to use within FSWs’ intimate relationships in Tijuana and Ciudad Juárez, Mexico, where HIV prevalence is increasing. Methods FSWs and their verified intimate (non-commercial) male partners completed quantitative and qualitative interviews from 2010–2012. Our complementary mixed methods design followed an iterative process to assess microbicide acceptability, explore related relationship dynamics, and identify factors associated with concern about male partners’ anger regarding microbicide use. Results Among 185 couples (n=370 individuals), interest in microbicides was high. In qualitative interviews with 28 couples, most participants were enthusiastic about microbicides for sex work contexts but some explained that microbicides could imply mistrust/infidelity within their intimate relationships. In the overall sample, nearly 1 in 6 participants (16%) worried that male partners would become angry about microbicides, which was associated with higher self-esteem among FSWs and lower self-esteem and past year conflict causing injury within relationships among men. Conclusions HIV prevention interventions should consider intimate relationship dynamics posing potential barriers to PrEP acceptability and adherence, involve male partners, and promote risk communication skills.

Smoking in pregnancy can cause substantial harm and, while many women quit, others continue to smoke throughout pregnancy. The role of partners is an important but relatively under-researched factor in relation to women's smoking in pregnancy; partner's smoking status and attitudes to smoking cessation are important influences in a pregnant women's attempt to quit. Further understanding of how partners perceive the barriers and facilitators to smoking cessation in pregnancy is needed, particularly from qualitative studies where participants describe these issues in their own words. A synthesis of qualitative research of partners' views of smoking in pregnancy and post-partum was conducted using meta-ethnography. Searches were undertaken from 1990 to January 2014 using terms for partner/household, pregnancy, post-partum, smoking, qualitative in seven electronic databases. The review was reported in accordance with the 'Enhancing transparency in reporting the synthesis of qualitative research' (ENTREQ) statement. Nine studies reported in 14 papers were included, detailing the experience of 158 partners; the majority were interviewed during the post-partum period. Partners were all male, with a single exception. Socioeconomic measures indicated that most participants were socially disadvantaged. The synthesis identified recurring smoking-related perceptions and experiences that hindered (barriers) and encouraged (facilitators) partners to consider quitting during the woman's pregnancy and into the post-partum period. These were represented in five lines of argument relating to: smoking being an integral part of everyday life; becoming and being a father; the couple's relationship; perceptions of the risks of smoking; and their harm reduction and quitting strategies. The cluster of identified barriers and facilitators to quitting offers pointers for policy and practice. The workplace emerges as an important space for and influence on partners' smoking habits, suggesting alternative cessation intervention locations for future parents. Conversely, health and community settings are seen to offer little support to fathers. Interventions centred on valued personal traits, like will-power and autonomy, may have particular salience. The review points, too, to the potential for health information that directly addresses perceived weaknesses in official advice, for example, around causal mechanisms and effects and around contrary evidence of healthy babies born to smokers.

QUEST: Qualifying Environmentally Sustainable Technologies

NASA Technical Reports Server (NTRS)

2006-01-01

Over the years, pollution prevention has proven to be a means to comply with environmental regulations, improve product performance and reduce costs. The NASA Acquisition Pollution Prevention (AP2) Program was created to help individual NASA Centers and programs work together to evaluate and adopt environmentally preferable technologies and practices. The AP2 Program accomplishes its mission using a variety of tools such as networking, information/technology exchange and partnering. Due to its extensive network of contacts, the AP2 Program is an excellent resource for finding existing solutions to problems. If no solution is readily known, the AP2 Program works to identify potential solutions and partners for demonstration/ validation projects. Partnering to prevent pollution is a cornerstone of NASA's prime mission and the One NASA Initiative. This annual newsletter highlights some of our program's collaborative efforts. I believe you will discover how the AP2 Program is responsive in meeting the Agency's environmental management strategic plans.

NASA Collaborative Approach Mitigates Environmentally-Driven Obsolescence

National Aeronautics and Space Administration (NASA) missions, like Department of Defense (DoD) organizations, require the rigorous testing and qualification of critical materials. Obsolescence supply risks created by environmental requirements can affect the cost, schedule and performance of NASA missions and the resilience of critical infrastructure. The NASA Technology Evaluation for Environmental Risk Mitigation (TEERM) Principal Center helps to identify obsolescence supply risks driven by environmental requirements and works proactively with NASA Centers and Programs, the DoD, the European Space Agency (ESA) and other agencies and partners to identify and evaluate environmentally friendly alternatives. TEERM tracks environmental regulations, identifies the potential loss of material availability and works with NASA programs and Centers to evaluate potential impacts through a risk assessment approach. TEERM collaborative projects identify, demonstrate and evaluate commercially viable alternative technologies and materials. A major focus during the Space Shuttle Program was the need to replace ozone depleting substances that were used in spray foam and cleaning applications. The potential obsolescence of coatings containing hexavalent chromium and the risks associated with lead free solder were also of concern for the Space Shuttle and present ongoing risks to new programs such as the Space Launch System. One current project teams NASA and ESA in the evaluation and testing of individual coatings and coating systems as replacements for hexavalent chromium coatings in aerospace applications. The proactive, collaborative approach used by TEERM helps reduce the cost burden on any one team partner, reduces duplication of effort, and enhances the technical quality and overall applicability of the testing and analysis.

Relationship between Hot Spot Residues and Ligand Binding Hot Spots in Protein-Protein Interfaces

PubMed Central

Zerbe, Brandon S.; Hall, David R.

2013-01-01

In the context of protein-protein interactions, the term “hot spot” refers to a residue or cluster of residues that makes a major contribution to the binding free energy, as determined by alanine scanning mutagenesis. In contrast, in pharmaceutical research a hot spot is a site on a target protein that has high propensity for ligand binding and hence is potentially important for drug discovery. Here we examine the relationship between these two hot spot concepts by comparing alanine scanning data for a set of 15 proteins with results from mapping the protein surfaces for sites that can bind fragment-sized small molecules. We find the two types of hot spots are largely complementary; the residues protruding into hot spot regions identified by computational mapping or experimental fragment screening are almost always themselves hot spot residues as defined by alanine scanning experiments. Conversely, a residue that is found by alanine scanning to contribute little to binding rarely interacts with hot spot regions on the partner protein identified by fragment mapping. In spite of the strong correlation between the two hot spot concepts, they fundamentally differ, however. In particular, while identification of a hot spot by alanine scanning establishes the potential to generate substantial interaction energy with a binding partner, there are additional topological requirements to be a hot spot for small molecule binding. Hence, only a minority of hot spots identified by alanine scanning represent sites that are potentially useful for small inhibitor binding, and it is this subset that is identified by experimental or computational fragment screening.

Patel, Ronak B.; Ahn, Roy; Burke, Thomas F.

2010-01-01

Human trafficking continues to persist, affecting up to 200 million people worldwide. As clinicians in emergency departments commonly encounter victims of intimate partner violence, some of these encounters will be with trafficking victims. These encounters provide a rare opportunity for healthcare providers to intervene and help. This case report of a human trafficking patient from a teaching hospital illustrates the complexity in identifying these victims. Clinicians can better identify potential trafficking cases by increasing their awareness of this phenomenon, using qualified interpreters, isolating potential victims by providing privacy and using simple clear reassuring statements ensuring security. A multidisciplinary approach can then be mobilized to help these patients. PMID:21293753

Cell-cell recognition and social networking in bacteria

PubMed Central

Troselj, Vera; Cao, Pengbo; Wall, Daniel

2018-01-01

SUMMARY The ability to recognize self and to recognize partnering cells allows microorganisms to build social networks that perform functions beyond the capabilities of the individual. In bacteria, recognition typically involves genetic determinants that provide cell surface receptors or diffusible signaling chemicals to identify proximal cells at the molecular level that can participate in cooperative processes. Social networks also rely on discriminating mechanisms to exclude competing cells from joining and exploiting their groups. In addition to their appropriate genotypes, cell-cell recognition also requires compatible phenotypes, which vary according to environmental cues or exposures as well as stochastic processes that leads to heterogeneity and potential disharmony in the population. Understanding how bacteria identify their social partners and how they synchronize their behaviors to conduct multicellular functions is an expanding field of research. Here we review recent progress in the field and contrast the various strategies used in recognition and behavioral networking. PMID:29194914

Subjective Sleep Quality in Women With Divorce Histories: The Role of Intimate Partner Victimization.

Newton, Tamara L; Burns, Vicki Ellison; Miller, James J; Fernandez-Botran, G Rafael

2016-05-01

A marital status of divorced or separated, as opposed to married, predicts increased risk of health problems, but not for all persons. Focusing on one established health risk that has been linked with divorce--poor subjective sleep quality--the present cross-sectional study examined whether a history of physical intimate partner victimization (IPV) helps identify divorced women at potentially greater risk of health problems. Community midlife women with divorce histories, all of whom were free of current IPV, reported on their past month sleep quality and lifetime IPV. The predicted odds of poor sleep quality were significantly greater for women with, versus without, IPV histories. This held after adjusting for socioemotional, medical, or sociodemographic risks. A dose-response relationship between IPV chronicity and poor quality sleep was observed. IPV history may help identify divorced women at increased risk of poor quality sleep and, more broadly, poor health. © The Author(s) 2015.

2015-01-01

A disintegrin and metalloproteinases (ADAMs) constitute a protein family essential for extracellular signaling and regulation of cell adhesion. Catalytic activity of ADAMs and their predicted potential for Src-homology 3 (SH3) domain binding show a strong correlation. Here we present a comprehensive characterization of SH3 binding capacity and preferences of the catalytically active ADAMs 8, 9, 10, 12, 15, 17, and 19. Our results revealed several novel interactions, and also confirmed many previously reported ones. Many of the identified SH3 interaction partners were shared by several ADAMs, whereas some were ADAM-specific. Most of the ADAM-interacting SH3 proteins were adapter proteins or kinases, typically associated with sorting and endocytosis. Novel SH3 interactions revealed in this study include TOCA1 and CIP4 as preferred partners of ADAM8, and RIMBP1 as a partner of ADAM19. Our results suggest that common as well as distinct mechanisms are involved in regulation and execution of ADAM signaling, and provide a useful framework for addressing the pathways that connect ADAMs to normal and aberrant cell behavior.

2015-06-01

Perinatal distress is a significant public health problem that adversely impacts the individual and their family. The primary objective of this systematic review and meta-analysis was to identify factors that partners can modify to protect each other from developing perinatal depression and anxiety. In accordance with the PRISMA statement, we reviewed the risk and protective factors associated with perinatal depression and anxiety symptoms that partners can potentially modify without professional assistance (PROSPERO reference CRD42014007524). Participants were new or expectant parents aged 16 years or older. The partner factors were sub-grouped into themes (e.g., instrumental support) based on a content analysis of the scale items and measure descriptions. A series of meta-analyses were conducted to estimate the pooled effect sizes of associations. We included 120 publications, reporting 245 associations with depression and 44 with anxiety. Partner factors with sound evidence that they protect against both perinatal depression and anxiety are: emotional closeness and global support. Partner factors with a sound evidence base for depression only are communication, conflict, emotional and instrumental support, and relationship satisfaction. This review is limited by the lack of generalizability to single parents and the inability to systematically review moderators and mediators, or control for baseline symptoms. The findings suggest that future prevention programs targeting perinatal depression and anxiety should aim to enhance relationship satisfaction, communication, and emotional closeness, facilitate instrumental and emotional support, and minimize conflict between partners.

Activated ALK and ROS1 tyrosine kinases, through gene fusions, has been found in lung adenocarcinomas and are highly sensitive to selective kinase inhibitors. This study aimed at identifying the presence of these rearrangements in human colorectal adenocarcinoma (CRC) specimens using a 4-target, 4-color break-apart fluorescence in situ hybridization (FISH) assay to simultaneously determine the genomic status of ALK and ROS1. Among the clinical CRC specimens analyzed, rearrangement-positive cases for both ALK and ROS1 were observed. The fusion partner for ALK was identified as EML4 and the fusion partner for one of the ROS1-positive cases was SLC34A2, the partner for the other ROS1-positive case remains to be identified. A small fraction of specimens presented duplicated or clustered copies of native ALK and ROS1. In addition, rearrangements were detected in samples that also harbored KRAS and BRAF mutations in two of the three cases. Interestingly, the ALK-positive specimen displayed marked intra-tumoral heterogeneity and rearrangement was also identified in regions of high-grade dysplasia. Despite the additional oncogenic events and tumor heterogeneity observed, elucidation of the first cases of ROS1 rearrangements and confirmation of ALK rearrangements support further evaluation of these genomic fusions as potential therapeutic targets in CRC. Implications ROS1 and ALK fusions occur in colorectal cancer and may have substantial impact in therapy selection. PMID:24296758

Provoked vestibulodynia is a female genital pain condition that results in sexual dysfunction and impacts negatively on the couple. Although patients' causal attributions have been linked to worse psychosexual outcomes, no study has documented the male partners' perspective of this distressing problem and its potential influence on their psychosexual adaptation. To identify whether male partners' attributions for vestibulodynia are possible predictors of their dyadic adjustment, sexual functioning, sexual satisfaction, and psychological distress, as well as of women's pain and sexual functioning. Thirty-eight women with vestibulodynia first completed measures of pain intensity and sexual functioning. Male partners responded to mailed questionnaires assessing their own attributions for genital pain as well as their psychological distress, relationship adjustment, sexual functioning, and sexual satisfaction. Women completed the McGill-Melzack Pain Questionnaire (MPQ) and the Female Sexual Function Index (FSFI). Attributions of male partners were measured using an adapted version of the Attributional Style Questionnaire (ASQ)-Partner Version. Men also filled out the Brief Symptom Inventory (BSI), the Dyadic Adjustment Scale (DAS), the Sexual History Form (SHF), and the Global Measure of Sexual Satisfaction (GMSEX). All four negative attribution dimensions and higher levels of women's pain intensity successfully predicted increased psychological distress in male partners. Higher levels of both internal and global attributions were associated with men's poorer dyadic adjustment, whereas global and stable attributions were related to their lower sexual satisfaction. Attributions failed to significantly predict sexual functioning in male partners and women's pain and sexual functioning. Evaluation and treatment of sexual pain problems should involve both partners and should explore the role of negative attributions.

Complex network theory for the identification and assessment of candidate protein targets.

PubMed

McGarry, Ken; McDonald, Sharon

2018-06-01

In this work we use complex network theory to provide a statistical model of the connectivity patterns of human proteins and their interaction partners. Our intention is to identify important proteins that may be predisposed to be potential candidates as drug targets for therapeutic interventions. Target proteins usually have more interaction partners than non-target proteins, but there are no hard-and-fast rules for defining the actual number of interactions. We devise a statistical measure for identifying hub proteins, we score our target proteins with gene ontology annotations. The important druggable protein targets are likely to have similar biological functions that can be assessed for their potential therapeutic value. Our system provides a statistical analysis of the local and distant neighborhood protein interactions of the potential targets using complex network measures. This approach builds a more accurate model of drug-to-target activity and therefore the likely impact on treating diseases. We integrate high quality protein interaction data from the HINT database and disease associated proteins from the DrugTarget database. Other sources include biological knowledge from Gene Ontology and drug information from DrugBank. The problem is a very challenging one since the data is highly imbalanced between target proteins and the more numerous nontargets. We use undersampling on the training data and build Random Forest classifier models which are used to identify previously unclassified target proteins. We validate and corroborate these findings from the available literature. Copyright © 2018 Elsevier Ltd. All rights reserved.

This study investigates the differential functioning of cultural and intellectual openness (the two aspects of Openness to Experience) in relation to social cognitive processes by examining how they influence people's perceptions and interpretations of social information when deciding to initiate working relationships. Using a policy-capturing design, 681 adult participants were asked to rate their similarity to and preference to work with potential work partners characterized by varying nationalities and levels of work-related competence. Multilevel moderated mediation was conducted to simultaneously evaluate whether the indirect effects of potential work partners' characteristics (i.e., nationalities and levels of work-related competence) on work partner preference through perceived similarity were moderated by cultural and intellectual openness. Perceived similarity mediated the relationships between work partner nationality and work-related competence and participants' work partner preferences. Furthermore, the negative indirect effect of work partner nationality on work partner preference via perceived similarity was attenuated by cultural openness, and the positive indirect effect of work partner work-related competence on work partner preference via perceived similarity was strengthened by intellectual openness. Cultural and intellectual openness may have distinct functions that influence how people perceive, evaluate, and appreciate social information when making social judgments. © 2016 Wiley Periodicals, Inc.

Recent reports indicate that vibrator use during solo and partnered sexual activities is common among heterosexual men and women in the United States. However, little research has comprehensively assessed vibrator use among gay and bisexually identified men. This study sought to document the extent to which gay and bisexually identified men report using vibrators, the sexual and relational situations within which they use them, and how men use vibrators on their own and their partners' bodies. Data were collected from 25,294 gay and bisexually identified men from 50 U.S. states and from the District of Columbia via an internet-based survey. Measures included sociodemographics, health-related indicators, sexual behaviors, and those related to recent and past use of vibrators during solo and partnered sexual interactions with other men. Approximately half (49.8%) of gay and bisexually identified men reported having used vibrators. Most men who had used a vibrator in the past reported use during masturbation (86.2%). When used during partnered interactions, vibrators were incorporated into foreplay (65.9%) and intercourse (59.4%). Men reported frequent insertion of vibrators into the anus or rectum when using them during masturbation (87.3%), which was also common during partnered interactions (∼60%), but varied slightly for casual and relationship sex partners. For both masturbation and partnered interactions, men overwhelmingly endorsed the extent to which vibrator use contributed to sexual arousal, orgasm, and pleasure. Vibrator use during both solo and partnered sexual acts was common among the gay and bisexually identified men in this sample and was described by men as adding to the quality of their sexual experiences. © 2010 International Society for Sexual Medicine.

Low rates of antenatal care (ANC) service uptake limit the potential impact of mother-to-child HIV-prevention strategies. Zambézia province, Mozambique, has one of the lowest proportions of ANC uptake among pregnant women in the country, despite the availability of free services. We sought to identify factors influencing ANC service uptake (including HIV counseling and testing) through qualitative methods. Additionally, we encouraged discussion about strategies to improve uptake of services. We conducted 14 focus groups to explore community views on these topics. Based on thematic coding of discourse, two main themes emerged; (1) gender inequality in decision making and responsibility for pregnancy and (2) community beliefs that uptake of ANC services, particularly if supported by a male partner, reflects a woman’s HIV-positive status. Interventions to promote ANC uptake must work to shift cultural norms through male partner participation. Potential strategies to promote male engagement in ANC services are discussed. PMID:25854615

Effective Identification of Akt Interacting Proteins by Two-Step Chemical Crosslinking, Co-Immunoprecipitation and Mass Spectrometry

PubMed Central

Huang, Bill X.; Kim, Hee-Yong

2013-01-01

Akt is a critical protein for cell survival and known to interact with various proteins. However, Akt binding partners that modulate or regulate Akt activation have not been fully elucidated. Identification of Akt-interacting proteins has been customarily achieved by co-immunoprecipitation combined with western blot and/or MS analysis. An intrinsic problem of the method is loss of interacting proteins during procedures to remove non-specific proteins. Moreover, antibody contamination often interferes with the detection of less abundant proteins. Here, we developed a novel two-step chemical crosslinking strategy to overcome these problems which resulted in a dramatic improvement in identifying Akt interacting partners. Akt antibody was first immobilized on protein A/G beads using disuccinimidyl suberate and allowed to bind to cellular Akt along with its interacting proteins. Subsequently, dithiobis[succinimidylpropionate], a cleavable crosslinker, was introduced to produce stable complexes between Akt and binding partners prior to the SDS-PAGE and nanoLC-MS/MS analysis. This approach enabled identification of ten Akt partners from cell lysates containing as low as 1.5 mg proteins, including two new potential Akt interacting partners. None of these but one protein was detectable without crosslinking procedures. The present method provides a sensitive and effective tool to probe Akt-interacting proteins. This strategy should also prove useful for other protein interactions, particularly those involving less abundant or weakly associating partners. PMID:23613850

The hyperbolic step potential: Anti-bound states, SUSY partners and Wigner time delays

DOE Office of Scientific and Technical Information (OSTI.GOV)

Gadella, M.; Kuru, Ş.; Negro, J., E-mail: jnegro@fta.uva.es

We study the scattering produced by a one dimensional hyperbolic step potential, which is exactly solvable and shows an unusual interest because of its asymmetric character. The analytic continuation of the scattering matrix in the momentum representation has a branch cut and an infinite number of simple poles on the negative imaginary axis which are related with the so called anti-bound states. This model does not show resonances. Using the wave functions of the anti-bound states, we obtain supersymmetric (SUSY) partners which are the series of Rosen–Morse II potentials. We have computed the Wigner reflection and transmission time delays formore » the hyperbolic step and such SUSY partners. Our results show that the more bound states a partner Hamiltonian has the smaller is the time delay. We also have evaluated time delays for the hyperbolic step potential in the classical case and have obtained striking similitudes with the quantum case. - Highlights: • The scattering matrix of hyperbolic step potential is studied. • The scattering matrix has a branch cut and an infinite number of poles. • The poles are associated to anti-bound states. • Susy partners using antibound states are computed. • Wigner time delays for the hyperbolic step and partner potentials are compared.« less

Insight into the Role of Ca2+-Binding Protein 5 in Vesicle Exocytosis

Purpose. CaBP5 is a neuronal calmodulin-like Ca2+-binding protein that is expressed in the retina and in the cochlea. Although CaBP5 knockout mice displayed reduced sensitivity of retinal ganglion cell light responses, the function of CaBP5 in vivo is still unknown. To gain further insight into CaBP5 function, the authors screened for CaBP5-interacting partners. Methods. Potential retinal interacting partners for CaBP5 were identified using affinity chromatography followed by mass spectrometry and by yeast two-hybrid screening of a bovine retina cDNA library. Interacting partners were further analyzed using coimmunoprecipitation. Immunohistochemistry and subcellular fractionation were performed to determine their colocalization in the retina. The effect of CaBP5 on dopamine release and neurite outgrowth of PC12 cells was analyzed using ELISA and fluorescent labeling. Results. Using affinity chromatography, the authors identified Munc18–1 and myosin VI as interacting partners for CaBP5. Munc18–1 was also identified using the yeast two-hybrid system. Colocalization and coimmunoprecipitation of CaBP5 with these two proteins in retinal tissue further established their physiological interactions. Furthermore, CaBP5 expression in NGF-stimulated PC12 cells stimulates neurite outgrowth and dopamine exocytosis. Conclusions. This study shows that CaBP5 interacts with Munc18–1 and myosin VI, two proteins involved in the synaptic vesicle cycle. Together with the effect of CaBP5 in stimulating neurite outgrowth and vesicle exocytosis in PC12 cells, these results suggest that CaBP5 plays a role in neurotransmitter release. PMID:22039235

On an individual level, human body odors carry information about whether a person is an eligible mate. The current studies investigate if body odors also transmit information about individuals being potential partners in more general terms, namely in regards to gender and sexual orientation. In study 1, 14 gay and 14 heterosexual men were presented with body odors obtained from potential partners (gay male and heterosexual female body odors, respectively) and heterosexual male body odor as a control. In study 2, 14 lesbian and 14 heterosexual women were presented with lesbian female and heterosexual male body odors representing body odors of potential partners, and heterosexual female body odor as a control. Central nervous processing was analyzed using chemosensory event-related potentials and current source density analysis (64-channel EEG recording). Gay and heterosexual men responded with shorter P2 latencies to the body odors of their preferred sexual partners, and lesbian women responded with shorter P2 latencies to body odors of their preferred gender. In response to heterosexual male body odors, lesbian women displayed the most pronounced P3 amplitude, and distinct neuronal activation in medial frontal and parietal neocortical areas. A similar pattern of neuronal activation was observed in gay men when presented with heterosexual male body odor. Both the early processing advantage (P2) for desirable partners' body odors as well as the enhanced evaluative processing (P3, CSD) of undesirable partners' body odors suggest that human body odors indeed carry information about individuals being potential partners in terms of gender and sexual orientation.

Timely notification and treatment of sex partners exposed to a sexually transmitted disease (STD) is essential to reduce reinfection and transmission. Our objectives were to determine factors associated with patient-initiated notification of sex partners and preferences regarding standard partner referral versus expedited partner therapy (EPT). Participants diagnosed with gonorrhea, chlamydia, trichomoniasis, or nongonococcal urethritis within the previous year were administered a baseline survey asking about demographics, sexual history, and partner treatment preferences (standard partner referral vs. EPT). They identified up to 4 sex partners within the past 2 months, and answered questions on relationship characteristics, quality, and notification self-efficacy. At follow-up, participants with a current STD were asked whether they notified their partners. Generalized estimating equations were used to evaluate the associations between predictor variables and partner notification. Of the 201 subjects enrolled, 157 had a current STD diagnosis, and 289 sex partners were identified. The rate of successful partner notification was 77.3% (157/203 sex partners). Partner notification was increased if the subject had a long-term relationship with a sex partner (odds ratio: 3.07; 95% confidence interval: 1.43, 6.58), considered the partner to be a main partner (odds ratio: 2.53; 95% confidence interval: 1.43, 6.58), or had increased notification self-efficacy. Overall, participants did not prefer EPT over standard referral; however, females, those with higher education levels, and those with a prior STD preferred EPT. Patient-initiated partner referral is more successful in patients with increased self-efficacy who have stronger interpersonal relationships with their sex partners.

Violated and vulnerable: women's experiences of contracting a sexually transmitted infection from a male partner.

To explore women's stories of contracting a sexually transmitted infection from a male partner and elucidate the gendered constructs and violence experienced that made the women vulnerable to these infections. Violence against women can result in both physical and psychological consequences and expose women to multiple health risks including sexual health adversity. Feminist storytelling approach. Qualitative interviews were conducted with 10 women. All data underwent thematic analysis. Findings from this study revealed the women were vulnerable to contracting sexually transmitted infection/s from their male sexual partners as a result of unequal gender and abusive relationship dynamics. Subsequently, contracting a sexual infection within this context potentially increased their vulnerability in both current and future relationships, through their loss of self-confidence and perceived ability to have a trusting loving heterosexual relationship as women with sexually transmitted infection/s. Women in relationships in which they are subordinate to their male partner are at heightened risk of sexual health adversity, including contracting a sexually transmitted infection. Contracting a sexually transmitted infection within the context of an abusive relationship can further increase women's vulnerability to dominant male partners, thus further exposure to sexual risk and adversity. Nurses working in clinical settings are well placed to conduct opportunistic screening of women's sexual health, including assessment of sexually transmitted infections and the nature of the encounter in which they were contracted. Thorough assessment can potentially identify relationship and personal factors that can increase a woman's risk to both sexual adversity and forms of abuse. Also, if women do divulge that they have suffered abuse, nurses are positioned to provide support and guidance in implementing strategies to minimise risk as well as referring them to specialised services. © 2017 John Wiley & Sons Ltd.

African American women who have sex with women (WSW) are emerging as a population at risk for sexually transmitted infections (STIs). The objectives of this study were to explore partnership characteristics for a cohort of African American WSW and evaluate those characteristics as potential risk factors for STIs. In addition, we aimed to determine STI diagnoses and identify predictors of STI infection. Women who have sex with women presenting to a sexually transmitted disease clinic in Birmingham, AL, completed a questionnaire and were tested for bacterial vaginosis, trichomoniasis, chlamydia, gonorrhea, Mycoplasma genitalium, syphilis, HIV, and herpes simplex virus type 2. A total of 163 women were enrolled: 78 WSW and 85 women who have sex with women and men (WSWM) (based on report of past year sexual behavior). Both WSW and WSWM reported similar numbers of female partners over the lifetime, past year, and past month; however, WSWM reported significantly more lifetime male partners, thus having a higher overall number of sexual partners. Women who have sex with women and men were more likely to report new or casual partner(s), group sex, history of STIs, and sex with partner(s) known to have STIs. Overall, WSWM were more likely to have a current diagnosis of bacterial vaginosis, a current diagnosis of a curable STI, or a diagnosis of a noncurable STI (85% vs. 56%, P < 0.01). African American WSW are not a homogeneous group, and their sexual health may be directly or indirectly influenced by male partners. A better understanding of the distinctions and differences between African American WSW and WSWM will enable health care providers to improve the quality of care provided.

Semi-structured interviews with open-ended questions on key domains of partnership effectiveness were conducted with a random stratified sample of participants varying by level of involvement. Eleven partners representing grassroots community agencies, faith-based organizations, service providers, and academic institutions. Common themes identified by an evaluation consultant and partners relating to partnership effectiveness, perceived benefits and costs, and future expectations. Findings underscore the importance of considering the potential issues that may arise with the increasing diversity of partners and perspectives. Many of the challenges and facilitating factors that arise within academic-community partnerships were similarly experienced between the diverse set of community partners. Challenges that affected partnership development between community-to-community partners included differences in expectations regarding the final goal of the project, trust-building, and the distribution of funds. Despite such challenges, partners were able to jointly develop a final set of recommendations for the creation of restoration centers, which was viewed as a major accomplishment. Limited guidance exists on how to navigate differences that arise between community members who have shared identities on some dimensions (eg, African American ethnicity, Los Angeles residence) but divergent identities on other dimensions (eg, formal church affiliation). With increasing diversity of community representation, careful attention needs to be dedicated to not only the development of academic-community partnerships but also community-community partnerships.

Background Factors related to specific sexual encounters can influence condom use during these encounters. These situation-specific factors have not been adequately studied in resource-poor countries where HIV infection has in some areas reached epidemic levels. This study was undertaken to identify situation-specific factors associated with condom use among 465 female bar and hotel workers in Moshi, Tanzania. Methods We conducted a case-crossover study in which women provided information about their most recent unprotected and protected sexual encounters. Conditional logistic regression was used to estimate paired odds ratios and 95% confidence intervals for the association between situation-specific factors and condom use. Results A subject-based or mutual decision about condom use (compared with partner based), casual partner type, a first-time sexual encounter and receiving gifts in exchange for sex were independently associated with increased odds of condom use, while sex at home and sex with a partner more than 10 years older was associated with reduced odds of use. There was also effect modification between partner type and decision-making: subject-based or mutual decisions were more protective with casual than regular partners; also, when the partner made the decisions about condom use, the type of partner had no effect. Conclusions Decision-making about condom use is a potentially modifiable predictor of unprotected sex, but its effect varies by partner type. Behavioural interventions are needed that encourage discussion about condom use and increase women's self-efficacy, but other types of interventions as well as female-controlled HIV prevention methods are needed for women in regular partnerships.

One in 4 women is affected by intimate partner violence in her lifetime. This article reports on a cross-sectional survey to estimate community preferences for health states resulting from intimate partner violence. A secondary analysis was conducted of data from a convenience sample of 93 abused and 138 nonabused women (231 total) recruited for in-person interviews from hospital outpatient department waiting rooms in metropolitan Boston, Massachusetts. SF-12 data were converted to utilities to describe community-perspective preferences for health states associated with intimate partner violence. Linear regression analysis was used to explore the association between violence and utility while controlling for other health and demographic factors. Median utility for intimate partner violence was between 0.58 and 0.63 on a scale of 0 (equivalent to death) to 1.0 (equivalent to optimal health), with a range from 0.64 to 0.66 for less severe violence to 0.53 to 0.62 for more severe violence. The data do not reveal whether violence itself is responsible for lower utility or whether a constellation of factors contributes to disutility experienced by women victims of abuse. The utility of health states experienced by women exposed to intimate partner violence is substantially diminished compared with optimal health and even other health conditions. These values quantify the substantial negative health impact of the experience of intimate partner violence in terms that allow comparison across diseases. They can be used in cost-effectiveness analyses to identify the benefits and potential returns from resources allocated to violence prevention and intervention efforts.

Public-private partnerships with large corporations: setting the ground rules for better health.

PubMed

Galea, Gauden; McKee, Martin

2014-04-01

Public-private partnerships with large corporations offer potential benefits to the health sector but many concerns have been raised, highlighting the need for appropriate safeguards. In this paper we propose five tests that public policy makers may wish to apply when considering engaging in such a public-private partnership. First, are the core products and services provided by the corporation health enhancing or health damaging? In some cases, such as tobacco, the answer is obvious but others, such as food and alcohol, are contested. In such cases, the burden of proof is on the potential partners to show that their activities are health enhancing. Second, do potential partners put their policies into practice in the settings where they can do so, their own workplaces? Third, are the corporate social responsibility activities of potential partners independently audited? Fourth, do potential partners make contributions to the commons rather than to narrow programmes of their choosing? Fifth, is the role of the partner confined to policy implementation rather than policy development, which is ultimately the responsibility of government alone? Copyright © 2014 Elsevier Ireland Ltd.

Cash transfer programs have the potential to prevent the spread of HIV, particularly among adolescents. One mechanism through which these programs may work is by influencing the characteristics of the people adolescents choose as sex partners. We examined the four-year impact of a Kenyan cash transfer program on partner age, partner enrollment in school, and transactional sex-based relationships among 684 adolescents. We found no significant impact of the program on partner characteristics overall, though estimates varied widely by gender, age, schooling, and economic status. Results highlight the importance of context in exploring the potential HIV preventive effects of cash transfers.

Strategies for partner notification for sexually transmitted infections, including HIV.

Ferreira, Adel; Young, Taryn; Mathews, Catherine; Zunza, Moleen; Low, Nicola

Partner notification (PN) is the process whereby sexual partners of an index patient are informed of their exposure to a sexually transmitted infection (STI) and the need to obtain treatment. For the person (index patient) with a curable STI, PN aims to eradicate infection and prevent re-infection. For sexual partners, PN aims to identify and treat undiagnosed STIs. At the level of sexual networks and populations, the aim of PN is to interrupt chains of STI transmission. For people with viral STI, PN aims to identify undiagnosed infections, which can facilitate access for their sexual partners to treatment and help prevent transmission. To assess the effects of different PN strategies in people with STI, including human immunodeficiency virus (HIV) infection. We searched electronic databases (the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE) without language restrictions. We scanned reference lists of potential studies and previous reviews and contacted experts in the field. We searched three trial registries. We conducted the most recent search on 31 August 2012. Published or unpublished randomised controlled trials (RCTs) or quasi-RCTs comparing two or more PN strategies. Four main PN strategies were included: patient referral, expedited partner therapy, provider referral and contract referral. Patient referral means that the patient notifies their sexual partners, either with (enhanced patient referral) or without (simple patient referral) additional verbal or written support. In expedited partner therapy, the patient delivers medication or a prescription for medication to their partner(s) without the need for a medical examination of the partner. In provider referral, health service personnel notify the partners. In contract referral, the index patient is encouraged to notify partner, with the understanding that the partners will be contacted if they do not visit the health service by a certain date. We analysed data according to paired partner referral strategies. We organised the comparisons first according to four main PN strategies (1. enhanced patient referral, 2. expedited partner therapy, 3. contract referral, 4. provider referral). We compared each main strategy with simple patient referral and then with each other, if trials were available. For continuous outcome measures, we calculated the mean difference (MD) with 95% confidence intervals (CI). For dichotomous variables, we calculated the risk ratio (RR) with 95% CI. We performed meta-analyses where appropriate. We performed a sensitivity analysis for the primary outcome re-infection rate of the index patient by excluding studies with attrition of greater than 20%. Two review authors independently assessed the risk of bias and extracted data. We contacted study authors for additional information. We included 26 trials (17,578 participants, 9015 women and 8563 men). Five trials were conducted in developing countries. Only two trials were conducted among HIV-positive patients. There was potential for selection bias, owing to the methods of allocation used and of performance bias, owing to the lack of blinding in most included studies. Seven trials had attrition of greater than 20%, increasing the risk of bias.The review found moderate-quality evidence that expedited partner therapy is better than simple patient referral for preventing re-infection of index patients when combining trials of STIs that caused urethritis or cervicitis (6 trials; RR 0.71, 95% CI 0.56 to 0.89, I(2) = 39%). When studies with attrition greater than 20% were excluded, the effect of expedited partner therapy was attenuated (2 trials; RR 0.8, 95% CI 0.62 to 1.04, I(2) = 0%). In trials restricted to index patients with chlamydia, the effect was attenuated (2 trials; RR 0.90, 95% CI 0.60 to 1.35, I(2) = 22%). Expedited partner therapy also increased the number of partners treated per index patient (three trials) when compared with simple patient referral in people with chlamydia or gonorrhoea (MD 0.43, 95% CI 0.28 to 0.58) or trichomonas (MD 0.51, 95% CI 0.35 to 0.67), and people with any STI syndrome (MD 0.5, 95% CI 0.34 to 0.67). Expedited partner therapy was not superior to enhanced patient referral in preventing re-infection (3 trials; RR 0.96, 95% CI 0.60 to 1.53, I(2) = 33%, low-quality evidence). Home sampling kits for partners (four trials) did not result in lower rates of re-infection in the index case (measured in one trial), or higher numbers of partners elicited (three trials), notified (two trials) or treated (one trial) when compared with simple patient referral. There was no consistent evidence for the relative effects of provider, contract or other patient referral methods. In one trial among men with non-gonococcal urethritis, more partners were treated with provider referral than with simple patient referral (MD 0.5, 95% CI 0.37 to 0.63). In one study among people with syphilis, contract referral elicited treatment of more partners than provider referral (MD 2.2, 95% CI 1.95 to 2.45), but the number of partners receiving treatment was the same in both groups. Where measured, there was no statistical evidence of differences in the incidence of adverse effects between PN strategies. The evidence assessed in this review does not identify a single optimal strategy for PN for any particular STI. When combining trials of STI causing urethritis or cervicitis, expedited partner therapy was more successful than simple patient referral for preventing re-infection of the index patient but was not superior to enhanced patient referral. Expedited partner therapy interventions should include all components that were part of the trial intervention package. There was insufficient evidence to determine the most effective components of an enhanced patient referral strategy. There are too few trials to allow consistent conclusions about the relative effects of provider, contract or other patient referral methods for different STIs. More high-quality RCTs of PN strategies for HIV and syphilis, using biological outcomes, are needed.

When and why do ideal partner preferences affect the process of initiating and maintaining romantic relationships?

PubMed

Eastwick, Paul W; Finkel, Eli J; Eagly, Alice H

2011-11-01

Three studies explored how the traits that people ideally desire in a romantic partner, or ideal partner preferences, intersect with the process of romantic relationship initiation and maintenance. Two attraction experiments in the laboratory found that, when participants evaluated a potential romantic partner's written profile, they expressed more romantic interest in a partner whose traits were manipulated to match (vs. mismatch) their idiosyncratic ideals. However, after a live interaction with the partner, the match vs. mismatch manipulation was no longer associated with romantic interest. This pattern appeared to have emerged because participants reinterpreted the meaning of the traits as they applied to the partner, a context effect predicted by classic models of person perception (S. E. Asch, 1946). Finally, a longitudinal study of middle-aged adults demonstrated that participants evaluated a current romantic partner (but not a partner who was merely desired) more positively to the extent that the partner matched their overall pattern of ideals across several traits; the match in level of ideals (i.e., high vs. low ratings) was not relevant to participants' evaluations. In general, the match between ideals and a partner's traits may predict relational outcomes when participants are learning about a partner in the abstract and when they are actually in a relationship with the partner, but not when considering potential dating partners they have met in person.

Objectives. We sought to identify HIV-infection risk factors related to partner selection and sexual behaviors with those partners among men who have sex with men (MSM) in King County, Washington. Methods. Participants were recruited from HIV testing sites in the Seattle area. Recent HIV infection status was determined by the Serologic Testing Algorithm for Recent HIV Seroconversion (STARHS) or a self-reported previous HIV-negative test. Data on behaviors with 3 male partners were collected via computer-based self-interviews. Generalized estimating equation models identified partnership factors associated with recent infection. Results. We analyzed data from 32 HIV-positive MSM (58 partners) and 110 HIV-negative MSM (213 partners). In multivariate analysis, recent HIV infection was associated with meeting partners at bathhouses or sex clubs, bars or dance clubs, or online; methamphetamine use during unprotected anal intercourse; and unprotected anal intercourse, except with HIV-negative primary partners. Conclusions. There is a need to improve efforts to promote condom use with casual partners, regardless of their partner's HIV status. New strategies to control methamphetamine use in MSM and to reduce risk behaviors related to meeting partners at high-risk venues are needed. PMID:18445808

CD6 and Linker of Activated T Cells are Potential Interaction Partners for T Cell-Specific Adaptor Protein.

The T cell-specific adaptor protein (TSAd) contains several protein interaction domains, and is merging as a modulator of T cell activation. Several interaction partners for the TSAd proline-rich region and phosphotyrosines have been identified, including the Src and Tec family kinases lymphocyte-specific protein tyrosine kinase and interleukin 2-inducible T cell kinase. Via its Src homology 2 (SH2) domain, TSAd may thus function as a link between these enzymes and other signalling molecules. However, few binding partners to the TSAd SH2 domain in T cells are hitherto known. Through the use of in silico ligand prediction, peptide spot arrays, pull-down and immunoprecipitation experiments, we here report novel interactions between the TSAd SH2 domain and CD6 phosphotyrosine (pTyr) 629 and linker of activated T cells (LAT) pTyr 171 , pTyr 191 and pTyr 226 . © 2016 The Foundation for the Scandinavian Journal of Immunology.

The Alliance Hypothesis for Human Friendship

PubMed Central

DeScioli, Peter; Kurzban, Robert

2009-01-01

Background Exploration of the cognitive systems underlying human friendship will be advanced by identifying the evolved functions these systems perform. Here we propose that human friendship is caused, in part, by cognitive mechanisms designed to assemble support groups for potential conflicts. We use game theory to identify computations about friends that can increase performance in multi-agent conflicts. This analysis suggests that people would benefit from: 1) ranking friends, 2) hiding friend-ranking, and 3) ranking friends according to their own position in partners' rankings. These possible tactics motivate the hypotheses that people possess egocentric and allocentric representations of the social world, that people are motivated to conceal this information, and that egocentric friend-ranking is determined by allocentric representations of partners' friend-rankings (more than others' traits). Methodology/Principal Findings We report results from three studies that confirm predictions derived from the alliance hypothesis. Our main empirical finding, replicated in three studies, was that people's rankings of their ten closest friends were predicted by their own perceived rank among their partners' other friends. This relationship remained strong after controlling for a variety of factors such as perceived similarity, familiarity, and benefits. Conclusions/Significance Our results suggest that the alliance hypothesis merits further attention as a candidate explanation for human friendship. PMID:19492066

Knowledge of HIV status can be important in reducing the risk of HIV exposure. In a European sample of men-who-have-sex-with-men (MSM), we aimed to identify factors associated with HIV serostatus disclosure to the most recent anal intercourse (AI) partner. We also aimed to describe the impact of HIV serostatus disclosure on HIV exposure risks. During 2013 and 2014, 4901 participants were recruited for the bio-behavioural Sialon-II study in 13 European cities. Behavioural data were collected with a self-administered paper questionnaire. Biological specimens were tested for HIV antibodies. Factors associated with HIV serostatus disclosure with the most recent AI partner were examined using bivariate and multilevel multivariate logistic regression analysis. We also describe the role of serostatus disclosure for HIV exposure of the most recent AI partner. Thirty-five percent (n = 1450) of the study participants reported mutual serostatus disclosure with their most recent AI partner or disclosed having HIV to their partner. Most of these disclosures occurred between steady partners (74%, n = 1077). In addition to the type of partner and HIV diagnosis status, other factors positively associated with HIV serostatus disclosure in the multilevel multivariate logistic regression model were recent testing, no condom use, and outness regarding sexual orientation. Disclosure rates were lowest in three south-eastern European cities. Following condom use (51%, n = 2099), HIV serostatus disclosure (20%, n = 807) was the second most common prevention approach with the most recent AI partner, usually resulting in serosorting. A potential HIV exposure risk for the partner was reported by 26% (111/432) of HIV antibody positive study participants. In 18% (20/111) of exposure episodes, an incorrect HIV serostatus was unknowingly communicated. Partner exposures were equally distributed between steady and non-steady partners. The probability of HIV exposure through condomless AI is substantially lower after serostatus disclosure compared to non-disclosure. Incorrect knowledge of one's HIV status contributes to a large proportion of HIV exposures amongst European MSM. Maintaining or improving condom use for anal intercourse with non-steady partners, frequent testing to update HIV serostatus awareness, and increased serostatus disclosure particularly between steady partners are confirmed as key aspects for reducing HIV exposures amongst European MSM.

Since the late 1990s, health departments and STD programs throughout the U.S. have used technologies, such as the internet and mobile phones, to provide services to persons with a sexually transmitted infection, including HIV, and their sex partners, also known as partner services. This study reviewed the published literature to assess and compare partner services outcomes as a result of using technology and to calculate cost savings through cases averted. We conducted a structured literature review of all U.S. studies that examined the use of technology to notify persons exposed to an STD (syphilis, chlamydia, gonorrhea), including HIV, by health care professionals in the U.S. from 2000 to 2017. Outcome measures, including the number of the number of partners notified, screened or tested; and new positives identified, were captured and cost savings were calculated, when data were available. Seven studies were identified. Methods used for partner services differed across studies, although email was the primary mode in 6 (83%) of the 7 studies. Only 2 of the 7 studies compared use of technology for partner services to traditional partner services. Between 10% and 97% of partners were successfully notified of their exposure through the use of technology and between 34% and 81% were screened or tested. Five studies reported on new infections identified, which ranged from 3-19. Use of technology for partner serves saved programs between $22,795 and $45,362 in direct and indirect medical costs. Use of technology for partner services increased the number of partners notified, screened or tested, and new infections found. Importantly, the use of technology allowed programs to reach partners who otherwise would not have been notified of their exposure to an STD or HIV. Improved response times and time to treatment were also seen as was re-engagement into care for previous HIV positive patients. Data and outcome measures across the studies were not standardized, making it difficult to generalize conclusions. Although not a replacement for traditional partner services, the use of technology enhances partner service outcomes.

The IPV-GBM scale: a new scale to measure intimate partner violence among gay and bisexual men.

Stephenson, Rob; Finneran, Catherine

The paper describes the creation of a new scale to measure intimate partner violence (IPV) among gay and bisexual men. Seven focus group discussions were held with gay and bisexual men, focusing on defining intimate partner violence: 30 forms of IPV were identified. A venue-recruited sample of 912 gay and bisexual men was surveyed, examining definitional understanding and recent experiences of each of the 30 forms of IPV. Participants were also asked questions from the CDC definition of intimate partner violence and the short-form of the Conflicts Tactics Scale (CTS2S). Factor analysis of responses to the definitional questions was used to create the IPV-GBM scale, and the prevalence of intimate partner violence was compared with that identified by the CDC and CTS2S measures of intimate partner violence. A 23-item scale, with 5 unique domains, was created, with strong internal reliability (Cronbach Alpha >.90). The IPV-GBM scale mirrored both the CDC and CTS2S definitions of intimate partner violence, but contained additional domains such as controlling violence, monitoring behaviors, emotional violence, and HIV-related violence. The new scale identified a significantly higher prevalence of IPV than either of the more commonly used measures. The results presented here provide encouraging evidence for a new, more accurate measure of intimate partner violence among gay and bisexual men in the U.S.

International fieldwork placements (IFPs) have become very popular among healthcare students including those in occupational therapy programmes. There are many potential benefits that can accrue to the students; however, there are critiques of international placements especially for students going to underserviced areas. The purpose of this paper is to provide a case study/model programme description that critically reflects on six partnerships in three underserviced countries that provide IFPs to students from one Canadian university. The personal opinions of each partner were collected verbally, by email and by a qualitative review of the past 10 years of partnership interaction. Some of the benefits reported by partners include the development of an increased number of sustainable long-term quality placements, orientation materials, student supports and the involvement of university faculty in research and capacity building projects in partner countries. A number of challenges were identified including the need for an expanded formal agreement, more bilateral feedback and examination of supervision models. This paper examines a limited number of partnerships with only one Canadian partner. Direct input of students is not utilized, although feedback given to co-authors by students is reflected. More research is needed on perspectives of partners in IFPs, impact of IFPs on clinical practice in student's home countries, impact of IFPS on underserviced areas and effective strategies for debriefing.

2011-01-01

In 2011, the U.S. Department of the Interior Southeast Climate Science Center (CSC) finalized the first draft of its goals for research needed to address the needs of natural and cultural partners for climate science in the Southeastern United States. The science themes described in this draft plan were established to address the information needs of ecoregion conservation partnerships, such as the Landscape Conservation Cooperatives (LCCs) and other regional conservation-science and resource-management partners. These themes were developed using priorities defined by partners and stakeholders in the Southeast and on a large-scale, multidisciplinary project-the Southeast Regional Assessment Project (SERAP)-developed in concert with those partners. Science products developed under these themes will provide models of potential future conditions, assessments of likely impacts, and tools that can be used to inform the conservation management decisions of LCCs and other partners. This information will be critical as managers try to anticipate and adapt to climate change. Resource managers in the Southeast are requesting this type of information, in many cases as a result of observed climate change effects. The Southeast CSC draft science plan identifies six science themes and frames the activities (tasks, with examples of recommended near-term work for each task included herein) related to each theme that are needed to achieve the objectives of the Southeast CSC.

Is shared misery double misery?

Mervin, Merehau Cindy; Frijters, Paul

2014-04-01

The literature has shown strong associations between health, financial and social life events and mental health. However, no studies as yet have looked at the temporal nature of the effects of life events on stated mental health nor have they included the effects of the events befalling partners within a household. This paper looks at the spillover in mental health, measured with the SF-36 scale, from one partner to the other, using life events to identify this relationship. We propose a new model that allows for both a temporal spacing of effects (anticipation and adaptation) as well as a spillover factor, which we define as the degree to which the events that are experienced by the partner affect us in the same way as if these events were to happen to us. We use data from 51,380 person-year observations of the Household, Income and Labour Dynamics in Australia survey (2002-10) which consistently measures nine distinct events, including illnesses, social shocks and financial shocks. We find that the events befalling a partner on average have an effect about 15% as large as the effect of own events. We use the estimates to compute the compensation required to offset own and partner's life events. The methodology in this paper is potentially useful for estimating other spillover parameters such as the effects of others in the family or in the neighbourhood. Copyright © 2014 Elsevier Ltd.

One of the principal goals of the participants in the International Space Station program is to provide a management support structure which is equitable and fair to all participants, responsive to the needs of users, responsible to other partners, and mutually supportive to the participation of other partners. Shared-utilization, shared-cost, and shared-operations policies considerations are discussed. Special attention is given to the methodology for identifying costs and benefits of this program, in which each partner should be provided with benefits in proportion to his contribution, and no partner would be forced to share in cost the inefficiencies introduced by other partners. The Space Station hierarchy of operations functions are identified, and the recommended framework planning and control hierarchy is presented.

Evolution of plant–pollinator mutualisms in response to climate change

Gilman, R Tucker; Fabina, Nicholas S; Abbott, Karen C; Rafferty, Nicole E

2012-01-01

Climate change has the potential to desynchronize the phenologies of interdependent species, with potentially catastrophic effects on mutualist populations. Phenologies can evolve, but the role of evolution in the response of mutualisms to climate change is poorly understood. We developed a model that explicitly considers both the evolution and the population dynamics of a plant–pollinator mutualism under climate change. How the populations evolve, and thus whether the populations and the mutualism persist, depends not only on the rate of climate change but also on the densities and phenologies of other species in the community. Abundant alternative mutualist partners with broad temporal distributions can make a mutualism more robust to climate change, while abundant alternative partners with narrow temporal distributions can make a mutualism less robust. How community composition and the rate of climate change affect the persistence of mutualisms is mediated by two-species Allee thresholds. Understanding these thresholds will help researchers to identify those mutualisms at highest risk owing to climate change. PMID:25568025

To find the fit that is most apt for the current situation in Korea and to find new ways of identifying potential partners for the purpose of public-private partnership (PPP). The research was conducted using domestic and international literature where the concept and definition of PPP was stated, and cases of PPP reported by the World Health Organization and cases in developed countries were investigated. Data were collected from 237 PPP potential partner organization, government agencies, and the government under a special law, local governments, businesses, hospitals, and private organizations through their internet webpage. The Delphi questionnaire was given to relevant institutions and questionnaire was surveyed general hospitals. Groups that were likely to realize most of the partnership were nonprofit or nongovernmental organizations, the central government, the private sector, public healthcare services, and products. In order to secure the position of exceptional comparative advantage of international expertise in the field of healthcare, we must implement PPP strategy that is in ordinance of domestic situation.

There is growing empirical evidence for an association between childhood abuse (CA) and intimate partner violence (IPV) in adulthood. We tested whether revictimized survivors of severe to extreme severities of child sexual abuse (CSA) and severe severities of child physical abuse (CPA) differed from nonvictimized healthy controls in their trait preferences in intimate partners and their current mate choice. In a sample of 52 revictimized female patients with posttraumatic stress disorder (PTSD) after CSA/CPA and 52 female healthy controls, the validated Intimate Partner Preferences Questionnaire (IPPQ) was used to assess (a) the desirability of tenderness, dominance, and aggression traits in potential partners, and (b) the presence of these traits in their current intimate partners. Factors potentially associated with partner preference and mate choice, for example, chronicity of traumatic events and lower self-esteem, were explored. Our results showed that, in general, revictimized PTSD patients did not have a preference for dominant or aggressive partners. However, revictimized women displayed a significantly larger discrepancy than did healthy controls between their preferences for tenderness traits and their ratings of the presence of tenderness traits in their current partners. Our results indicated that revictimized patients had lower self-esteem values; however, these values were associated with higher demands for tenderness traits. Furthermore, our results revealed that compared with patients who experienced early-onset childhood abuse (CA), those who experienced later onset CA were more accepting of dominant traits in potential partners. Women who had experienced IPV rated their current partners to be overly dominant. A higher tolerance of dominance traits might increase the risk of IPV in a specific subgroup of abused women (women with a later onset of abuse experiences and experiences of IPV).

Adolescent sexual development is not the same across the board, and can be seen as both normative as well as risky behavior, depending on factors such as age of onset and number of partners. This longitudinal study identified developmental trajectories of annual number of sexual partners from adolescence to emerging adulthood and their antecedents. From the ages of 16-22, 332 participants (60.8 % females) annually reported their number of sexual partners. Measures of adolescent and family characteristics taken at ages 13-15 were used as predictors. Group-based modeling identified four trajectory groups: the abstainers group (9.1 %), low-increasing group (30.6 %), medium-increasing group (53.0 %), and multiple-partners group (7.3 %). Multinomial logistical regressions indicated that better social competence increased chances of belonging to the multiple-partners group as compared to the abstainers and low-increasing groups, and more substance use predicted membership in the multiple-partners group as compared to the abstainers group. Moreover, females were overrepresented in the low-increasing and medium-increasing groups. These results imply a greater diversity in sexual development than proposed in the literature and highlight the importance of identifying the strengths and competencies associated with healthy sexual development along with the early risk factors.

Advice from working women with retired partners.

Cooley, Eileen L; Adorno, Gail

in the 21st century, as more women are employed full-time and couples increasingly share egalitarian values, more women continue employment after their partners have voluntarily retired. However, we know very little about the experiences of this growing population of women. We asked working women with retired partners to share their advice for other women who may face this developmental transition. Open-ended responses from 97 women were analyzed to identify pertinent issues and themes. Four primary content areas were identified: time management, division of household labor, financial planning, and communication. Communication between partners was both a topic of concern as well as the solution suggested to resolve conflicts or differences that may arise when women live with a retired partner. It is expected that future changes in the workforce and improvements in the gender balance within relationships will continue to impact experiences for working women with retired partners.

Universal screening for maternal depression and assessment of psychosocial risks has been integrated into the routine perinatal care provided in many Australian hospitals, but to date, partners/fathers have been largely excluded from the process. This study explored the ways in which clinicians in health service settings include partners who attend antenatal and postnatal visits with women. Qualitative data were collected using observations (n = 54), interviews (n = 60), and discussion groups (n = 7) with midwives and child and family health nurses who conducted the appointments. Transcripts from observations, interviews, and discussion groups underwent qualitative analysis, and key themes were identified. Results showed partners to have little or no involvement in psychosocial assessment and depression screening. Thematic analysis revealed four key themes: negotiating partner exclusion, partial inclusion, women's business or a couple concern? and they know anyway. Partner involvement appeared to be challenged particularly by mandatory interpersonal violence screening, which, according to health service policy, is to be conducted confidentially. Overall, results highlighted partner involvement in perinatal depression screening and psychosocial assessment processes and identified some of the benefits such as partner disclosure, but also the challenges and complexities of inclusion of partners. Clinical implications and directions for further education and research are discussed. © 2016 Michigan Association for Infant Mental Health.

This scoping review aims to identify the scope of current literature considering nurse/midwife educational practices in the areas of intimate partner violence to inform future nursing/midwifery educational policy and practice. Intimate partner violence is a global issue affecting a significant portion of the community. Healthcare professionals including nurses/midwives in hospital- and community-based environments are likely to encounter affected women and need educational strategies that support best practice and promote positive outcomes for abused women and their families. Scoping review of relevant literature from January 2000 to July 2015. Search of databases: CINHAL, MEDLINE, EMBASE, PROQUEST Central and COCHRANE Library. Reference lists from included articles were searched for relevant literature as were several grey literature sources. This review demonstrates low levels of undergraduate or postregistration intimate partner violence education for nursing/midwifery staff and students. Existing intimate partner violence education strategies are varied in implementation, method and content. Outcomes of these educational programmes are not always rigorously evaluated for staff or client-based outcomes. Further research is needed to evaluate existing intimate partner violence education programmes for nurses/midwives and identify the most effective strategies to promote improved clinical practice and outcomes for abused women and their families. Intimate partner violence has a significant social and public health impact. The World Health Organization has identified the need to ensure that healthcare professionals are adequately trained to meet the needs of abused women. Intimate partner violence education programmes, commencing at undergraduate studies for nurses/midwives, need to be implemented with rigorously evaluated programmes to ensure they meet identified objectives, promote best practice and improve care for abused women. © 2016 John Wiley & Sons Ltd.

ABCD1 and its homolog ABCD2 are peroxisomal ATP-binding cassette (ABC) half-transporters of fatty acyl-CoAs with both distinct and overlapping substrate specificities. Although it is established that ABC half-transporters have at least to dimerize to generate a functional unit, functional equivalents of tetramers (i.e. dimers of full-length transporters) have also been reported. However, oligomerization of peroxisomal ABCD transporters is incompletely understood but is of potential significance because more complex oligomerization might lead to differences in substrate specificity. In this work, we have characterized the quaternary structure of the ABCD1 and ABCD2 proteins in the peroxisomal membrane. Using various biochemical approaches, we clearly demonstrate that both transporters exist as both homo- and heterotetramers, with a predominance of homotetramers. In addition to tetramers, some larger molecular ABCD assemblies were also found but represented only a minor fraction. By using quantitative co-immunoprecipitation assays coupled with tandem mass spectrometry, we identified potential binding partners of ABCD2 involved in polyunsaturated fatty-acid metabolism. Interestingly, we identified calcium ATPases as ABCD2-binding partners, suggesting a role of ABCD2 in calcium signaling. In conclusion, we have shown here that ABCD1 and its homolog ABCD2 exist mainly as homotetramers in the peroxisomal membrane. PMID:28258215

The sodium-activated potassium channels Slick (Slo2.1, KCNT2) and Slack (Slo2.2, KCNT1) are paralogous channels of the Slo family of high-conductance potassium channels. Slick and Slack channels are widely distributed in the mammalian CNS and they play a role in slow afterhyperpolarization, generation of depolarizing afterpotentials and in setting and stabilizing the resting potential. In the present study we used a combined approach of (co)-immunoprecipitation studies, Western blot analysis, double immunofluorescence and mass spectrometric sequencing in order to investigate protein-protein interactions of the Slick and Slack channels. The data strongly suggest that Slick and Slack channels co-assemble into identical cellular complexes. Double immunofluorescence experiments revealed that Slick and Slack channels co-localize in distinct mouse brain regions. Moreover, we identified the small cytoplasmic protein beta-synuclein and the transmembrane protein 263 (TMEM 263) as novel interaction partners of both, native Slick and Slack channels. In addition, the inactive dipeptidyl-peptidase (DPP 10) and the synapse associated protein 102 (SAP 102) were identified as constituents of the native Slick and Slack channel complexes in the mouse brain. This study presents new insights into protein-protein interactions of native Slick and Slack channels in the mouse brain.

A means of improving public health in low- and middle-income countries? Benefits and challenges of international public-private partnerships.

In the last two decades international public-private partnerships have become increasingly important to improving public health in low- and middle-income countries. Governments realize that involving the private sector in projects for financing, innovation, development, and distribution can make a valuable contribution to overcoming major health challenges. Private-public partnerships for health can generate numerous benefits but may also raise some concerns. To guide best practice for public-private partnerships for health to maximize benefits and minimize risks, the first step is to identify potential benefits, challenges, and motives. We define motives as the reasons why private partners enter partnerships with a public partner. We conducted a systematic review of the literature using the PRISMA guidelines. We reviewed the literature on the benefits and challenges of public-private partnerships for health in low- and middle-income countries provided by international pharmaceutical companies and other health-related companies. We provide a description of these benefits, challenges, as well as of motives of private partners to join partnerships. An approach of systematic categorization was used to conduct this research. We identified six potential benefits, seven challenges, and three motives. Our main finding was a significant gap in the available academic literature on this subject. Further empirical research using both qualitative and quantitative approaches is required. From the limited information that is readily available, we conclude that public-private partnerships for health imply several benefits but with some noticeable and crucial limitations. In this article, we provide a description of these benefits and challenges, discuss key themes, and conclude that empirical research is required to determine the full extent of the challenges addressed in the literature.

Public health leaders increasingly recognize the importance of multi-sector partnerships and systems approaches to address obesity. Public-private partnerships (PPP), which are joint ventures between government agencies and private sector entities, may help facilitate this process, but need to be delivered through comprehensive, transparent frameworks to maximize potential benefits and minimize potential risks for all partners. The City University of New York (CUNY) School of Public Health and the Healthy Weight Commitment Foundation (HWCF) propose to engage in a unique academic-private-sector research partnership to evaluate the impact and effectiveness of the food and beverage industry's investment in obesity and hunger prevention and reduction through community-level healthful eating and active living programs. The CUNY-HWCF academic-private partnership protocol described here incorporates best practices from the literature on PPP into the partnership's design. The CUNY-HWCF partnership design demonstrates how established guidelines for partnership components will actively incorporate and promote the principles of successful PPPs identified in various research papers. These identified principles of successful PPP, including mutuality (a reciprocal relationship between entities), and equality among partners, recognition of partners' unique strengths and roles, alignment of resources and expertise toward a common cause, and coordination and delegation of responsibilities, will be embedded throughout the design of governance, management, funding, intellectual property and accountability structures. The CUNY-HWCF partnership responds to the call for increased multi-sector work in obesity prevention and control. This framework aims to promote transparency and the shared benefits of complementary expertise while minimizing shared risks and conflicts of interest. This framework serves as a template for future academic-private research partnerships.

Food access interventions are promising strategies for improving dietary intake, which is associated with better health. However, studies examining the relationship between food access and intake are limited to observational designs, indicating a need for more rigorous approaches. The Veggie Van (VV) program was a cluster-randomized intervention designed to address the gap between food access and intake. In this article, we aim to describe the approaches involved in recruiting community partners to participate in VV. The VV mobile market aimed to improve access to fresh fruits and vegetables by providing subsidized, high-quality, local produce in low-resource communities in North Carolina. This study describes the strategies and considerations involved in recruiting community partners and individual participants for participation in the VV program and evaluation. To recruit partners, we used various strategies, including a site screener to identify potential partners, interest forms to gauge future VV use and prioritize enrollment of a high-need population, marketing materials to promote VV, site liaisons to coordinate community outreach, and a memorandum of understanding between all invested parties. A total of 53 community organizations and 725 participants were approached for recruitment. Ultimately, 12 sites and 201 participants were enrolled. Enrollment took 38 months, but our approaches helped successfully recruit a low-income, low-access population. The process took longer than anticipated, and funding constraints prevented certain strategies from being implemented. Recruiting community partners and members for participation in a multi-level, community-based intervention was challenging. Strategies and lessons learned can inform future studies.

Factors linking childhood experiences to adult romantic relationships among African Americans.

It is well known that a high-quality relationship with a romantic partner is related to a variety of positive outcomes associated with health and well-being. Establishing such relationships is an important developmental task for young adults, and past research indicates that there is a link between experiences in the family of origin and the success of later intimate relationships. It has been suggested that this association can be explained by the acquisition of social competencies (e.g., emotions, schemas, traits) that are acquired during childhood in the family of origin and, in turn, influence interaction with adult romantic partners. The current study builds on this foundation by identifying particular competencies expected to explain the association between childhood exposure to supportive and harsh parenting and later patterns of interaction with romantic partners. Specifically, we examine anger management, attachment style, hostile attribution bias, and self-control as potential mediators using prospective, longitudinal data from a sample of 345 African American young adults. Results from structural equation modeling indicate that each of the mediators in our study accounts for a significant portion of the effect of parenting on the quality of adult romantic relationships, although the constructs linking parenting to warm interactions with romantic partners are somewhat different from those that link parenting to hostile interactions with romantic partners. Even after accounting for the effect of the mediators, there is still a direct effect of parenting on both warm/loving and hostile/aggressive interactions with romantic partner. Implications for theory and practice are discussed. PsycINFO Database Record (c) 2014 APA, all rights reserved.

The Internet has opened many doors with its accessibility to information, entertainment and web-based communities. For young men who have sex with men (YMSM), the Internet can provide access to information on relevant sexual behavior and health information, stories from other men about relationship issues, and a venue for locating potential sexual and dating partners. Understanding YMSM’s motivations for going online for information, advice or sexual relationships, is important as the Internet becomes increasingly used not only as a space to find sexual partners, but also as a venue for HIV and STI interventions. Having an understanding of the risks associated with searching for partners online, and how and why YMSM use the Internet for a variety of purposes, can inform the development of more effective Internet-based risk reduction programs. This manuscript presents qualitative and quantitative data from the Healthy Young Men’s Study, a longitudinal study of an ethnically diverse cohort of 526 YMSM. Qualitative interviews (N=24) described not only the prevalence of using the Internet for finding sexual partners and the possible benefits and risks associated with that practice, but also the processes and perceptions of using this mechanism. Our data indicate that YMSM use the Internet to find information related to sex and sexuality, seek friendships, sexual partners as well as “hook-ups” or casual sex. Findings are presented in relation to how YMSM researchers and interventionists can identify how to most effectively reach YMSM through online methods. PMID:20809373

The purpose of this study was to explore variations in demographics, culture, self-esteem and intimate partner violence among Hispanic women according to birthplace, and to identify factors that are associated with these differences in intimate partner violence. Baseline data from a randomized control trial testing the efficacy of an HIV prevention program was used. Path analyses identified differences in intimate partner violence between Colombian women and women from other Central/South American. Self-esteem was the only factor that was associated with these differences. Interventions that address the unique needs of Hispanic women from different subgroups are needed. PMID:23363655

Making One Health a reality: crossing bureaucratic boundaries: Chapter 18 in One Health

Rubin, Carol; Dunham, Bernadette; Sleeman, Jonathan

A One Health approach that achieves optimal outcomes requires that nontraditional partners come to a common table to identify solutions that transcend organization-specific mandates. This collaboration requires individuals to go beyond their accustomed comfort zones and function on teams with partners who very likely come from unfamiliar organizational, disciplinary, and even national cultures. Each participant represents a separate mandate and an individual corporate culture and values, and each potentially communicates in agency-specific or industry-prescribed cultural terms that may be foreign to the rest of the team. A recent review paper reports that such interdisciplinary teams are most likely to succeed when they have a unified task and a shared goal and values, and when personal relationships are developed from a foundation of trust and respect (1).

Adolescent Support Seeking as a Path to Adult Functional Independence

2017-01-01

The potential importance of depending on others during adolescence in order to establish independence in young adulthood was examined across adolescence to emerging adulthood. Participants included 184 teens (46% male; 42% non-White), their mothers, best friends, and romantic partners, assessed at ages 13–14, 18, 21–22, and 25. Path analyses showed that associations were both partner and age specific: markers of independence were predicted by participants’ efforts to seek support from mothers at age 13, best friends at 18, and romantic partners at 21. Importantly, analyses controlled for support seeking from these partners at other ages, as well as for other potentially confounding variables including attachment security, scholastic/job competence, and physical attractiveness over time. Moreover, analyses suggested the transfer of support seeking behavior from mothers to best friends to romantic partners over time based on support given by the previous partner at an earlier age.

This study assessed unprotected anal and oral sex behaviors of HIV-positive gay and bisexual men in New York City and San Francisco with their main and non-main sexual partners. Here we focus on the use of three harm reduction strategies (serosorting, strategic positioning, and withdrawal before ejaculation) in order to decrease transmission risk. The data from a baseline assessment of 1168 HIV-positive gay and bisexual men in the two cities were utilized. Men were recruited from a variety of community-based venues, through advertising and other techniques. City differences were identified, with more men in San Francisco reporting sexual risk behaviors across all partner types compared with men in New York City. Serosorting was identified, with men reporting significantly more oral and anal sex acts with other HIV-positive partners than with HIV-negative partners. However, men also reported more unprotected sex with partners of unknown status compared with their other partners. Some evidence of strategic positioning was identified, although differences were noted across cities and across different types of partners. Men in both cities reported more acts of oral sex without ejaculation than with ejaculation, but the use of withdrawal as a harm reduction strategy for anal sex was more common among men from San Francisco. Overall, evidence for harm reduction was identified; however, significant differences across the two cities were found. The complicated nature of the sexual practices of gay and bisexual men are discussed, and the findings have important implications for prevention efforts and future research studies.

Discovery of multiple interacting partners of gankyrin, a proteasomal chaperone and an oncoprotein--evidence for a common hot spot site at the interface and its functional relevance.

Gankyrin, a non-ATPase component of the proteasome and a chaperone of proteasome assembly, is also an oncoprotein. Gankyrin regulates a variety of oncogenic signaling pathways in cancer cells and accelerates degradation of tumor suppressor proteins p53 and Rb. Therefore gankyrin may be a unique hub integrating signaling networks with the degradation pathway. To identify new interactions that may be crucial in consolidating its role as an oncogenic hub, crystal structure of gankyrin-proteasome ATPase complex was used to predict novel interacting partners. EEVD, a four amino acid linear sequence seems a hot spot site at this interface. By searching for EEVD in exposed regions of human proteins in PDB database, we predicted 34 novel interactions. Eight proteins were tested and seven of them were found to interact with gankyrin. Affinity of four interactions is high enough for endogenous detection. Others require gankyrin overexpression in HEK 293 cells or occur endogenously in breast cancer cell line- MDA-MB-435, reflecting lower affinity or presence of a deregulated network. Mutagenesis and peptide inhibition confirm that EEVD is the common hot spot site at these interfaces and therefore a potential polypharmacological drug target. In MDA-MB-231 cells in which the endogenous CLIC1 is silenced, trans-expression of Wt protein (CLIC1_EEVD) and not the hot spot site mutant (CLIC1_AAVA) resulted in significant rescue of the migratory potential. Our approach can be extended to identify novel functionally relevant protein-protein interactions, in expansion of oncogenic networks and in identifying potential therapeutic targets. © 2013 Wiley Periodicals, Inc.

Metallomics investigations on potential binding partners of methylmercury in tuna fish muscle tissue using complementary mass spectrometric techniques.

PubMed

Kutscher, Daniel J; Sanz-Medel, Alfredo; Bettmer, Jörg

2012-08-01

In this study, the binding behaviour of methylmercury (MeHg(+)) towards proteins is investigated. Free sulfhydryl groups in cysteine residues are known to be the most likely binding partners, due to the high affinity of mercury to sulphur. However, detailed knowledge about discrete binding sites in living organisms has been so far scarce. A metallomics approach using different methods like size-exclusion chromatography (SEC) and liquid chromatography (LC) coupled to inductively coupled plasma-mass spectrometry (ICP-MS) as well as complementary mass spectrometric techniques (electrospray ionisation-tandem mass spectrometry, ESI-MS/MS) are combined to sequence and identify possible target proteins or peptides after enzymatic digestion. Potential targets for MeHg(+) in tuna fish muscle tissue are investigated using the certified reference material CRM464 as a model tissue. Different extraction procedures appropriate for the extraction of proteins are evaluated for their efficiency using isotope dilution analysis for the determination of total Hg in the extracts. Due to the high chemical stability of the mercury-sulphur bond, the bioconjugate can be quantitatively extracted with a combination of tris(hydroxymethyl)aminomethane (TRIS) and sodium dodecyl sulphate (SDS). Using different separation techniques such as SEC and SDS-polyacrylamide gel electrophoresis (SDS-PAGE) it can be shown that major binding occurs to a high-molecular weight protein (M(w) > 200 kDa). A potential target protein, skeletal muscle myosin heavy chain, could be identified after tryptic digestion and capillary LC-ESI-MS/MS.

This study explores the sexual behavior 27 men who have sex with men (MSM) who regularly engage in unprotected anal intercourse (UAI), in the context of HIV home test (HT) use with potential sex partners. Participants were given 16 HT kits to use over three months. Among 40 sexual occasions following HIV-negative HT results, there were 25 UAI occasions (16 based on not typically using condoms and nine on HT results), 15 occasions in which condoms were used, and three in which sex did not occur. In the seven occasions where a potential partner received HIV-positive HT results, the sexual encounter ended. Almost all participants encountered potential partners who refused HT. Over half of these participants ended sexual encounters when HT was refused, perceiving these partners as HIV-positive or too high risk. Some participants reported that HT use heightened their awareness of HIV risk and their commitment to reducing it. PMID:23657758

Having multiple sexual partners concurrently increases the risk of transmission of a sexually transmitted infection. Even if partnerships do not overlap, transmission potential exists when the gap between partnerships is shorter than the remaining infectious period. In the present article, we quantify the gap between partners to assess transmission potential using data collected by a cross-sectional survey of 2,203 genitourinary medicine clinic patients in England in 2009. Questionnaires asked about patients' 3 most recent partnerships. Gaps were calculated as time (days) between the last sexual encounter with a former partner and the first sexual encounter with the next partner. Among 1,875 patients who reported 1 or more partners in the previous 3 months, 47.6% of men and 27.7% of women reported 2 or more partners. Forty-two percent of the gaps were negative (i.e., partnerships that were concurrent); the median gaps were -7 and -17 days for men and women, respectively (i.e., overlaps were 7 and 17 days for men and women, respectively). Although half of the gaps were positive (serially monogamous partnerships), many were of short duration; the median gaps were 14 and 24 days for men and women, respectively. In over half of the gaps, condoms were used inconsistently with one or both partners, and in one-quarter, condoms were never used with either partner. There is thus a high potential for sexually transmitted infections, as even if partnerships are not behaviorally concurrent, they may be biologically concurrent. These data have important implications for designing and targeting effective health promotion messages.

Previously, we identified the stress-induced chaperone, Hsp27, as highly overexpressed in castration-resistant prostate cancer and developed an Hsp27 inhibitor (OGX-427) currently tested in phase I/II clinical trials as a chemosensitizing agent in different cancers. To better understand the Hsp27 poorly-defined cytoprotective functions in cancers and increase the OGX-427 pharmacological safety, we established the Hsp27-protein interaction network using a yeast two-hybrid approach and identified 226 interaction partners. As an example, we showed that targeting Hsp27 interaction with TCTP, a partner protein identified in our screen increases therapy sensitivity, opening a new promising field of research for therapeutic approaches that could decrease or abolish toxicity for normal cells. Results of an in-depth bioinformatics network analysis allying the Hsp27 interaction map into the human interactome underlined the multifunctional character of this protein. We identified interactions of Hsp27 with proteins involved in eight well known functions previously related to Hsp27 and uncovered 17 potential new ones, such as DNA repair and RNA splicing. Validation of Hsp27 involvement in both processes in human prostate cancer cells supports our system biology-predicted functions and provides new insights into Hsp27 roles in cancer cells.

The aims of this study were to identify partner attributes associated with sexually transmitted infections (STIs) among adolescents and to summarize implications for research and prevention. The design of this study was systematic review. We identified peer-reviewed studies published in 1990 through 2010 that assessed 1 or more partner attributes in relation to a biologically confirmed STI among adolescents (15-24 years) by searching MEDLINE and included articles. Studies that included adolescents but more than 50% of the sample or with mean or median age of 25 years or greater were excluded. Sixty-four studies met the eligibility criteria; 61% were conducted in high-income countries; 80% were cross sectional; and 91% enrolled females and 42% enrolled males. There was no standard "partner" definition. Partner attributes assessed most frequently included the following: age, race/ethnicity, multiple sex partners, and STI symptoms. Older partners were associated with prevalent STIs but largely unrelated to incidence. Black race was associated with STIs but not uniformly. Partners with multiple partners and STI symptoms seem to be associated with STIs predominantly among females. Although significant associations were reported, weaker evidence exists for the following: other partner sociodemographics, sexual and other behaviors (sexual concurrency, intimate partner violence, substance use, travel), and STI history. There were no apparent differences by STI. Partner attributes are independently associated with STIs among male and female adolescents worldwide. These findings reinforce the importance of assessing partner attributes when determining STI risk. Prevention efforts should continue to promote and address barriers to condom use. Increased efforts are needed to screen and treat STIs and reduce risky behavior among men. A standard partner definition would facilitate the interpretation of findings in future studies.

I Am Right for Your Child! : Tactics for Manipulating Potential Parents-In-Law.

Parents and children have converging as well as diverging interests with respect to the latter's mate choices. Diverging interests frequently result in children choosing mates who do not gain the approval of their parents. Manipulation then arises wherein parents try to drive away undesirable prospective sons- and daughters-in-law, and the latter employ counter manipulation to make the former to change their minds. The present research aims to identify and measure the effectiveness of manipulation tactics that individuals employ to influence their partners' parents to accept them as mates for their daughters and sons. Study 1 recruited a sample of 106 Greek-Cypriots and, using open-ended questionnaires, identified 41 acts that individuals employ on their partners' parents. Using principal-components analysis, in a sample of 738 Greek-Cypriots, Study 2 classified these acts into seven broader manipulation tactics and identified the ones that are more and the ones that are less likely to be employed. Study 3 examined in a sample of 414 Greek-Cypriots the effectiveness of these tactics in altering parents' minds and finds a moderate effectiveness, with some tactics being more effective than others. The implications of these findings are discussed.

Constructively engaging male partners in women-centred health programs such as family planning and prevention of mother-to-child HIV transmission has resulted in both improved health outcomes and stronger relationships. Concerted efforts to engage men in microbicide use could make it easier for women to access and use microbicides in the future. This paper synthesizes findings from studies that investigated men's role in their partners' microbicide use during clinical trials to inform recommendations for male engagement in women's microbicide use. We conducted primary and secondary analyses of data from six qualitative studies implemented in conjunction with microbicide clinical trials in South Africa, Kenya, and Tanzania. The analyses included data from 535 interviews and 107 focus groups with trial participants, male partners, and community members to answer research questions on partner communication about microbicides, men's role in women's microbicide use, and potential strategies for engaging men in future microbicide introduction. We synthesized the findings across the studies and developed recommendations. The majority of women in steady partnerships wanted agreement from their partners to use microbicides. Women used various strategies to obtain their agreement, including using the product for a while before telling their partners, giving men information gradually, and continuing to bring up microbicides until resistant partners acquiesced. Among men who were aware their partners were participating in a trial and using microbicides, involvement ranged from opposition to agreement/non-interference to active support. Both men and women expressed a desire for men to have access to information about microbicides and to be able to talk with a healthcare provider about microbicides. We recommend counselling women on whether and how to involve their partners including strategies for gaining partner approval; providing couples' counselling on microbicides so men have the opportunity to talk with providers; and targeting men with community education and mass media to increase their awareness and acceptance of microbicides. These strategies should be tested in microbicide trials, open-label studies, and demonstration projects to identify effective male engagement approaches to include in eventual microbicide introduction. Efforts to engage men must take care not to diminish women's agency to decide whether to use the product and inform their partners.

to develop greater understanding of how expectant fathers experience their partner's labour and the subsequent birth of their baby. a qualitative meta-synthesis. Data were search for in CINAHL, PubMed, Psych Info and SCOPUS. eight studies conducted in England, Malawi, Nepal and Sweden were included. 120 fathers with experiences of their partner having a spontaneous vaginal, assisted or surgical birth. 1st order themes were identified and subsequently grouped into seven 2nd order themes. Finally through a process of exploring patterns and connections seven 3rd order themes were developed which produced new insights into the men's experiences of labour and birth. This meta-synthesis revealed that most men wanted to be actively involved in their partner's labour, present at the birth and respected for what they could contribute. Men recognised that birth was a unique event that may be potentially challenging requiring a level of preparation. There were also men who felt pressured to attend. During the actual experience of labour men commonly expressed overwhelming feelings and inadequacy in their ability to support their partner. They particularly struggled with the 'pain' of labour. Midwives were subsequently identified as best placed to make a significant difference to how men perceived their experiences of labour and what they described as the life changing event of birth. the expectant fathers' birth experiences were multidimensional. Many were committed to being involved during labour and birth but often felt vulnerable. Being prepared and receiving support were essential elements of positive experience as well as contributing to their ability to adequately support the labouring woman. men's ability to actively prepare for, and be supported through, the labour and birth process influences their perceptions of the childbirth event as well as their sense of connection to their partner. Couples should be given opportunities to explore expectations and how these may influence their own construction of their role during the birth process. While the role of expectant fathers in labour and birth should be facilitated and supported arguably their wish not to participate should be afforded the same respect. Copyright © 2014 Elsevier Ltd.

Two genes are synthetically lethal (SL) when defects in both are lethal to a cell but a single defect is non-lethal. SL partners of cancer mutations are of great interest as pharmacological targets; however, identifying them by cell line-based methods is challenging. Here we develop MiSL (Mining Synthetic Lethals), an algorithm that mines pan-cancer human primary tumour data to identify mutation-specific SL partners for specific cancers. We apply MiSL to 12 different cancers and predict 145,891 SL partners for 3,120 mutations, including known mutation-specific SL partners. Comparisons with functional screens show that MiSL predictions are enriched for SLs in multiple cancers. We extensively validate a SL interaction identified by MiSL between the IDH1 mutation and ACACA in leukaemia using gene targeting and patient-derived xenografts. Furthermore, we apply MiSL to pinpoint genetic biomarkers for drug sensitivity. These results demonstrate that MiSL can accelerate precision oncology by identifying mutation-specific targets and biomarkers.

Intimate partner violence.

PubMed

Cronholm, Peter F; Fogarty, Colleen T; Ambuel, Bruce; Harrison, Suzanne Leonard

2011-05-15

Intimate partner violence is a common source of physical, psychological, and emotional morbidity. In the United States, approximately 1.5 million women and 834,700 men annually are raped and/or physically assaulted by an intimate partner. Women are more likely than men to be injured, sexually assaulted, or murdered by an intimate partner. Studies suggest that one in four women is at lifetime risk. Physicians can use therapeutic relationships with patients to identify intimate partner violence, make brief office interventions, offer continuity of care, and refer them for subspecialty and community-based evaluation, treatment, and advocacy. Primary care physicians are ideally positioned to work from a preventive framework and address at-risk behaviors. Strategies for identifying intimate partner violence include asking relevant questions in patient histories, screening during periodic health examinations, and case finding in patients with suggestive signs or symptoms. Discussion needs to occur confidentially. Physicians should be aware of increased child abuse risk and negative effects on children's health observed in families with intimate partner violence. Physicians also should be familiar with local and national resources available to these patients.

Factors influencing beliefs about intimate partner violence among adults in South Korea.

This study aimed to identify factors influencing beliefs about intimate partner violence among Korean adults. This is a cross-sectional descriptive study that analyzed data from 466 adults. Beliefs about intimate partner violence were measured using a self-report questionnaire with a total of 28 items consisting of four subscales: perpetrator's justification for beating women, blaming women for violence against them, perpetrator's responsibility for violence, and giving help to victims. Men and women had significantly different beliefs about intimate partner violence (t = -7.19, p < .001). Some characteristics were identified that led to unhealthy beliefs about intimate partner violence. Four variables-gender, age, educational level, and witnessing parental violence-had an explanatory power of 20% with regard to beliefs about IPV (F = 10.50, p = .000). In South Korea, men, older individuals, and those with less formal education or who have witnessed parental violence need education to foster healthier beliefs about intimate partner violence. Nurses can play a vital role in efforts to decrease intimate partner violence. © 2017 Wiley Periodicals, Inc.

Understanding the impact of Fc glycosylation on its conformational changes by molecular dynamics simulations and bioinformatics.

PubMed

Zhang, Yubo

2015-12-01

N-linked glycosylation of Fc at N297 plays an important role in its effector function, aberrance of which would cause disease pathogenesis. Here, we performed all-atom molecular dynamics simulations to explore the effects of Fc glycosylation on its dynamics behaviors. Firstly, equilibrium simulations suggested that Fc deglycosylation was able to induce residual flexibility in its CH2 domain. Besides, the free energy landscape revealed three minimum energy wells in deglycosylated Fc, representing its "open", "semi-closed" and "closed" states. However, we could only observe the "open" state of glycosylated Fc. Supportively, principal component analysis emphasized the prominent motion of delyclosylated Fc and dynamically depicted how it changed from the "open" state to its "closed" state. Secondly, we studied the recognition mechanism of the Fc binding to its partners. Energy decomposition analysis identified key residues of Fc to recognize its two partners P13 and P34. Evidently, electrostatic potential surfaces showed that electrostatic attraction helped to stabilize the interaction between Fc and its partners. Also, relative binding free energies explained different binding affinities in Fc-P13 and Fc-P34. Collectively, these results together provided the structural basis for understanding conformational changes of deglycosylated Fc and the recognition mechanism of the Fc binding to its partners.

Seasonal PrEP for partners of migrant miners in southern Mozambique: a highly focused PrEP intervention

Introduction To be used most effectively, pre-exposure prophylaxis (PrEP) should be prioritized to those at high risk of acquisition and would ideally be aligned with time periods of increased exposure. Identifying such time periods is not always straightforward, however. Gaza Province in southern Mozambique is characterized by high levels of HIV transmission and circular labour migration to mines in South Africa. A strong seasonal pattern in births is observable, reflecting an increase in conception in December. Given the potential for increased HIV transmission between miners returning in December and their partners in Gaza Province, PrEP use by the latter would be a useful means of HIV prevention, especially for couples who wish to conceive. Methods A mathematical model was used to represent population-level adult heterosexual HIV transmission in Gaza Province. Increased HIV acquisition among partners of miners in December, coinciding with the miners’ return from South Africa, is represented. In addition to a PrEP intervention, the scale-up of treatment and recent scale-up of male circumcision that have occurred in Gaza are represented. Results Providing time-limited PrEP to the partners of migrant miners, as opposed to providing PrEP all year, would improve the cost per infection averted by 7.5-fold. For the cost per infection averted to be below US$3000, at least 85% of PrEP users would need to be good adherers and PrEP would need to be cheaper than US$115 per person per year. Uncertainty regarding incidence of HIV transmission among partners of miners each year in December has a strong influence on estimates of cost per infection averted. Conclusions Providing time-limited PrEP to partners of migrant miners in Gaza Province during periods of increased exposure would be a novel strategy for providing PrEP. This strategy would allow for a better prioritized intervention, with the potential to improve the efficiency of a PrEP intervention considerably, as well as providing important reproductive health benefits.

Peroxiredoxins are ubiquitous thiol-dependent peroxidases for which chaperone and signaling roles have been reported in various types of organisms in recent years. In plants, the peroxidase function of the two typical plastidial 2-Cys peroxiredoxins (2-Cys PRX A and B) has been highlighted while the other functions, particularly in ROS-dependent signaling pathways, are still elusive notably due to the lack of knowledge of interacting partners. Using an ex vivo approach based on co-immunoprecipitation of leaf extracts from Arabidopsis thaliana wild-type and mutant plants lacking 2-Cys PRX expression followed by mass spectrometry-based proteomics, 158 proteins were found associated with 2-Cys PRXs. Already known partners like thioredoxin-related electron donors (Chloroplastic Drought-induced Stress Protein of 32kDa, Atypical Cysteine Histidine-rich Thioredoxin 2) and enzymes involved in chlorophyll synthesis (Protochlorophyllide OxidoReductase B) or carbon metabolism (Fructose-1,6-BisPhosphatase) were identified, validating the relevance of the approach. Bioinformatic and bibliographic analyses allowed the functional classification of the identified proteins and revealed that more than 40% are localized in plastids. The possible roles of plant 2-Cys PRXs in redox signaling pathways are discussed in relation with the functions of the potential partners notably those involved in redox homeostasis, carbon and amino acid metabolisms as well as chlorophyll biosynthesis.

Objective This study examined the attribution of MCI etiology assigned by individuals with MCI and their care-partners, and the extent to which the dyads agreed on the attribution of MCI etiology. Methods We conducted secondary analyses of cross-sectional data from a cohort of individuals with MCI (n=60) and their care-partners (n=60). The mean age of the individuals with MCI was 71.0±9.4 and of care-partners 64.2±11.0 years. The primary outcome was attribution assigned to memory deficits on the Illness Perception Questionnaire. We categorized the attribution of MCI etiology as either potentially controllable or uncontrollable factors. We described the distribution of MCI etiology with descriptive and contingency tables. We determined the odds of a patient or care-partner choosing one type of MCI etiology over another. Results Although individuals with MCI and their care-partners most frequently attributed MCI to uncontrollable factors (81.7% and 61.0%, respectively), care-partners were 28.41 [95% CI, 1.26 to 645.48] times more likely to attribute MCI etiology to potentially controllable factors than individuals with MCI. No significant associations between demographic factors and attribution of MCI etiology were found for the individuals with MCI or the care-partners. Conclusion Findings demonstrated that members of the dyad attributed MCI etiology to different causes. Attributions of MCI etiology should be explored by professionals to clarify misconceptions and potentially improve subsequent voluntary actions intended to assist oneself or others. PMID:24123240

Women exposed to intimate partner violence (IPV) and other forms of lifetime trauma may be at risk for negative mental health outcomes including posttraumatic stress disorder (PTSD). The purpose of this study was to examine potential predictors of PTSD among low-income women exposed to perinatal IPV. This study analyzed baseline cross-sectional data from 239 low-income pregnant women in the USA who participated in a nurse home visitation intervention between 2006 and 2012 after reporting recent IPV. PTSD was assessed with the Davidson Trauma Scale (DTS) in which participants answer questions about the most disturbing traumatic event (MDTE) in their lifetime that affected them the week before the interview. In total, 40 % of the women were identified as having PTSD (DTS ≥40). PTSD prevalence significantly increased with age to nearly 80 % of women ages 30 and older (n = 23). Age was also the strongest predictor of PTSD (p < 0.001). Most participants (65 %) identified non-IPV-related traumas as their MDTEs. Psychological (94 %), physical (82 %), and sexual (44 %) violence were not significantly associated with PTSD status. Despite recent exposure to IPV, most participants identified other traumatic events as more disturbing than IPV-related trauma. Further, the risk for PTSD increased with age, suggesting that the cumulative effect of trauma, which may include IPV, increases the risk for PTSD over a lifetime. Implementing comprehensive screening for trauma during prenatal care may lead to the early identification and treatment of PTSD during pregnancy in a community setting.

We analyzed fresh ART cycles uszing freshly ejaculated sperm from the male partner of couples undergoing ART cycles from 2004 until 2014. We recorded patient and partner demographic characteristics. The cohort was linked to hospital billing data to obtain information on selected male partners' comorbidities identified using ICD-9-CM codes. None. Fertilization, clinical pregnancy, miscarriage, implantation, and live-birth rates as well as birth weights and gestational ages. In all, we identified 2,690 men who underwent 5,037 fresh ART cycles. Twenty-seven percent of men had at least one medical diagnosis. Men with nervous system diseases had on average lower pregnancy rates (23% vs. 30%) and live-birth rates (15% vs. 23%) than men without nervous system diseases. Lower fertilization rates were also observed among men with respiratory diseases (61% vs. 64%) and musculoskeletal diseases (61% vs. 64%) relative to those without these diseases. In addition, men with diseases of the endocrine system had smaller children (2,970 vs. 3,210 g) than men without such diseases. Finally, men with mental disorders had children born at an earlier gestational age (36.5 vs. 38.0 weeks). The current report identified a possible relationship between a man's health history and IVF outcomes. As these are potentially modifiable factors, further research should determine whether treatment for men's health conditions may improve or impair IVF outcomes.

We introduce a method for constructing Darboux (or supersymmetric) pairs of pseudoscalar and scalar Dirac potentials that are associated with exceptional orthogonal polynomials. Properties of the transformed potentials and regularity conditions are discussed. As an application, we consider a pseudoscalar Dirac potential related to the Schrödinger model for the rationally extended radial oscillator. The pseudoscalar partner potentials are constructed under the first- and second-order Darboux transformations.

Addressing Intimate Partner Violence: Reducing Barriers and Improving Residents' Attitudes, Knowledge, and Practices.

2016-10-01

This study aims to assess residents' attitudes, knowledge, practices, and barriers in addressing intimate partner violence and create a curriculum targeting self-identified deficits. The authors developed and distributed a survey to residents across multiple specialties at a large academic institution. A workshop was developed using obstetrics/gynecology residents' data, with post-intervention data collected to assess for changes. One hundred forty-seven residents (41 %) completed the survey. Though all identified assessing intimate partner violence as physicians' responsibility, only 40 % reported consistent screening with new female patients, 36 % with pregnant patients, and 18 % with post-partum patients. Half reported inadequate training and felt unprepared to counsel patients regarding intimate partner violence. Post-intervention data suggest gains in knowledge and perceived preparedness. Although residents appreciate the significance of intimate partner violence assessment, in this particular institution few consistently perform or feel comfortable screening. Development of comprehensive intimate partner violence curricula is therefore critical.

The time-limited nature of health and public health research fellowships poses a challenge to trainees' and community partners' efforts to sustain effective, collaborative, community-based participatory research (CBPR) relationships. This paper presents CBPR case studies of partnerships between health services research trainees and community organization leaders in a medium-sized city to describe how participation in the partnership altered community partners' understanding and willingness to conduct research and to engage with research-derived data. Trainees and faculty used participatory methods with community leaders to identify research questions, and conduct and disseminate research. Throughout the process, trainees and faculty included research capacity building of community partners as a targeted outcome. Community partners were asked to reflect retrospectively on community research capacity building in the context of CBPR projects. Reflections were discussed and categorized by the authorship team, who grouped observations into topics that may serve as a foundation for development of future prospective analyses. Important ideas shared include that trainee participation in CBPR may have an enduring impact on the community by increasing the capacity of community partners and agencies to engage in research beyond that which they are conducting with the current trainee. We posit that CBPR with research trainees may have an additive effect on community research capacity when it is conducted in collaboration with community leaders and focuses on a single region. More research is needed to characterize this potential outcome.

Case studies of power and control related to tobacco use during pregnancy.

2007-01-01

The objective was to identify and describe elements of power and control evident in couple tobacco-related interaction patterns during pregnancy. Using a case study approach, elements of the Duluth Abuse Intervention Project Power and Control Wheel were used to examine women's experiences of tobacco reduction during pregnancy and post partum. Three cases were selected from a larger qualitative sample, using a maximum variation sampling approach. Although no direct evidence of partner abuse or violence accompanying partner efforts to influence women's smoking was described, most of the elements of power and control were present in the case study, and appeared to cause an emotional toll and a negative impact on women's ability to freely express their views about their own tobacco use. Elements of power and control, however subtle, are potentially important and unrecognized dimensions of women's tobacco reduction experiences. Additional care and attention should be taken in designing tobacco reduction interventions and policies directed at pregnant and post partum women and their partners to reduce the possibility that these interventions may contribute to the use of power and control.

The objective of this study is to examine risk factors of physical aggression against a partner in a large representative Active Duty Air Force sample. A stratified sample of 128,950 United States Active Duty members were invited to participate in an Air Force-wide anonymous online survey across 82 bases. The final sample (N = 52,780) was weighted to be representative of the United States Air Force. Backward stepwise regression analyses were conducted to identify unique predictors of partner physical aggression perpetration within and across different ecological levels (individual, family, organization, and community levels). Relationship satisfaction, alcohol problems, financial stress, and number of years in the military were identified as unique predictors of men's and women's perpetration of violence against their partner across ecological levels. Parental status, support from neighbors, personal coping, and support from formal agencies also uniquely predicted men's but not women's perpetration of violence across ecological levels. This study identified specific risk factors of partner violence that may be targeted by prevention and intervention efforts aimed at different levels of impact (e.g., family interventions, community-wide programs).

To identify facilitators and barriers that Health Canada's (HC) cross-sector partners experienced while implementing the Eat Well Campaign: Food Skills (EWC; 2013-2014) and describe how these experiences might differ according to distinct partner types. A qualitative study using hour-long semi-structured telephone interviews conducted with HC partners that were transcribed verbatim. Facilitators and barriers were identified inductively and analysed according partner types. Implementation of a national mass-media health education campaign. Twenty-one of HC's cross-sector partners (food retailers, media and health organizations) engaged in the EWC. Facilitators and barriers were grouped into seven major themes: operational elements, intervention factors, resources, collaborator traits, developer traits, partnership factors and target population factors. Four of these themes had dual roles as both facilitators and barriers (intervention factors, resources, collaborator traits and developer traits). Sub-themes identified as both facilitators and barriers illustrate the extent to which a facilitator can easily become a barrier. Partnership factors were unique facilitators, while operational and target population factors were unique barriers. Time was a barrier that was common to almost all partners regardless of partnership type. There appeared to be a greater degree of uniformity among facilitators, whereas barriers were more diverse and unique to the realities of specific types of partner. Collaborative planning will help public health organizations anticipate barriers unique to the realities of specific types of organizations. It will also prevent facilitators from becoming barriers. Advanced planning will help organizations manage time constraints and integrate activities, facilitating implementation.

Let the right one in: a microeconomic approach to partner choice in mutualisms.

One of the main problems impeding the evolution of cooperation is partner choice. When information is asymmetric (the quality of a potential partner is known only to himself), it may seem that partner choice is not possible without signaling. Many mutualisms, however, exist without signaling, and the mechanisms by which hosts might select the right partners are unclear. Here we propose a general mechanism of partner choice, "screening," that is similar to the economic theory of mechanism design. Imposing the appropriate costs and rewards may induce the informed individuals to screen themselves according to their types and therefore allow a noninformed individual to establish associations with the correct partners in the absence of signaling. Several types of biological symbioses are good candidates for screening, including bobtail squid, ant-plants, gut microbiomes, and many animal and plant species that produce reactive oxygen species. We describe a series of diagnostic tests for screening. Screening games can apply to the cases where by-products, partner fidelity feedback, or host sanctions do not apply, therefore explaining the evolution of mutualism in systems where it is impossible for potential symbionts to signal their cooperativeness beforehand and where the host does not punish symbiont misbehavior.

The mind bomb 1 (Mib1) ubiquitin ligase is essential for controlling metazoan development by Notch signaling and possibly the Wnt pathway. It is also expressed in postmitotic neurons and regulates neuronal morphogenesis and synaptic activity by mechanisms that are largely unknown. We sought to comprehensively characterize the Mib1 interactome and study its potential function in neuron development utilizing a novel sequential elution strategy for affinity purification, in which Mib1 binding proteins were eluted under different stringency and then quantified by the isobaric labeling method. The strategy identified the Mib1 interactome with both deep coverage and the ability to distinguish high-affinity partners from low-affinity partners. A total of 817 proteins were identified during the Mib1 affinity purification, including 56 high-affinity partners and 335 low-affinity partners, whereas the remaining 426 proteins are likely copurified contaminants or extremely weak binding proteins. The analysis detected all previously known Mib1-interacting proteins and revealed a large number of novel components involved in Notch and Wnt pathways, endocytosis and vesicle transport, the ubiquitin-proteasome system, cellular morphogenesis, and synaptic activities. Immunofluorescence studies further showed colocalization of Mib1 with five selected proteins: the Usp9x (FAM) deubiquitinating enzyme, alpha-, beta-, and delta-catenins, and CDKL5. Mutations of CDKL5 are associated with early infantile epileptic encephalopathy-2 (EIEE2), a severe form of mental retardation. We found that the expression of Mib1 down-regulated the protein level of CDKL5 by ubiquitination, and antagonized CDKL5 function during the formation of dendritic spines. Thus, the sequential elution strategy enables biochemical characterization of protein interactomes; and Mib1 analysis provides a comprehensive interactome for investigating its role in signaling networks and neuronal development.

Black men who have sex with men and women (BMSMW) are at increased HIV risk, but few efficacious interventions meet their unique needs. Three HIV prevention interventions were evaluated with a common protocol. Baseline data were pooled to describe sexual behavior involving transmission risk with male, female, and male-to-female transgender partners and identify factors associated with transmission risk. BMSMW from Los Angeles, Philadelphia, and Chicago who reported sexual risk and bisexual behavior in the past year were recruited via modified chain referral sampling and community recruitment. Baseline assessments were conducted via audio computer-assisted interview and sexual behaviors assessed over the past 3 months. From December 2010 to November 2012, 584 BMSMW were enrolled across the three cities. More than half (55%) were recruited by other participants. Overall, the mean age was 43 years. Seventy-five percent reported an annual income <$10,000 and selling sex was prevalent (31%). Three-quarters identified as bisexual. Thirty-nine percent were HIV-positive. Among HIV-positive participants, 46% reported sex without condoms with HIV-negative or unknown male partners and 45% with HIV-negative or unknown female partners. Overall, factors associated with sex without condoms included network size, education, income, sexual orientation identification, HIV status, exchange sex, homonegativity, and social support. Findings support the need for enhanced HIV prevention efforts for this population. Future studies should examine contextual factors in addition to individual risk behaviors to inform the development and implementation of promising strategies to prevent HIV and promote the overall health and wellness of BMSMW and their sexual partners.

Recent nationally representative studies documenting event-level sexual behavior have included samples that are predominantly heterosexual, resulting in limited information on the sexual repertoire of gay and bisexually identified men. This study sought to document the sexual behaviors that gay and bisexually identified men report during their most recent male-partnered sexual event and to describe the situational characteristics and participants' evaluation of these events. Via an internet-based survey, data were collected from 24,787 gay and bisexually identified men (ages 18-87 years) from 50 US states and the District of Columbia. Measures included items related to sociodemographics, recent sexual behavior history, situational characteristics, orgasm, and ratings of arousal and pleasure. Participants' mean age was 39.2 years; ethnicities included white (84.6%), Latino (6.4%), and African American (3.6%); and most men (79.9%) identified as homosexual. The most commonly reported behavior was kissing a partner on the mouth (74.5%), followed by oral sex (72.7%), and partnered masturbation (68.4%). Anal intercourse occurred among less than half of participants (37.2%) and was most common among men ages 18-24 (42.7%). Sex was most likely to occur in the participant's home (46.8%), with less frequently reported locations including hotels (7.4%) and public spaces (3.1%). The number of behaviors engaged in during last sexual event varied with most (63.2%) including 5-9 different sexual behaviors. These data provide one of the first examinations of sexual behaviors during the most recent male-partnered sexual event among gay and bisexually identified men in the United States. Findings from this study suggest that gay and bisexually identified men have a diverse sexual repertoire and that partnered sexual behaviors are not limited solely to acts of penile insertion. © 2011 International Society for Sexual Medicine.

Objectives Relationship dynamics influence the perception of HIV risk in sexual dyads. The objective of this study was to examine the effect of relational dynamics on knowledge or perception of a partner's HIV status in a sample of most at-risk men who have sex with men (MSM): drug-using male sex workers. The study identified relationship dimensions and examined their association with misperceptions about a particular partner's HIV status. Methods The analytical sample for the study consisted of 168 sexual partnerships of 116 male sex workers and their associates. Exploratory factor analysis was conducted to identify dimensions of the interpersonal relationships in sexual partnerships that were then regressed on ‘risky misperceptions’ (misperceiving HIV negative when partner's self-report was positive or unknown). Results Six relationship dimensions of intimate, commitment, socialising, financial, trust and honesty were extracted. Commitment was found to be protective against misperception (adjusted OR (AOR)=0.45), while trust was not (AOR=2.78). Other factors also were found to be associated with misperception. HIV-negative MSM (AOR=7.69) and partners who were both self-identified as gay (AOR=3.57) were associated with misperception, while encounters identified as sex work (AOR=0.29), in which both partners were Caucasian (AOR=0.16), and involved with an older partner (AOR=0.90) were protective. Conclusions Couple-based HIV intervention efforts among MSM should consider that less trust and more commitment are protective factors in sexual partnerships. PMID:25305211

This study focused on self-perceived mate value of young adult survivors of childhood cancer relative to healthy peers. Qualitative studies indicate potential problems surrounding romantic relationships among survivors, but systematic studies are missing. One-hundred forty-nine childhood cancer survivors and 149 matched controls completed online questionnaires about their mate value, social comparison strategies (i.e., upward/downward identifying/contrasting strategies), and marital status. Survivors and controls were aged 20-40 (M = 27.8), 55% were female, and survivors had been treated for brain tumors (n = 52; 35%), leukemia (n = 42; 28%), lymphoma (n = 31; 21%), or other solid tumors (n = 24; 16%) at 5-33 years before study participation. Survivors and controls did not differ on overall mate value, but on individual characteristics: Survivors thought they had a better sense of humor (d = 0.36), were more loyal (d = 0.32), had higher social status (d = 0.26), and were more ambitious (d = 0.19), while also considering themselves less sexually adventurous (d = 0.31), less healthy (d = 0.26), having less desire to have children (d = 0.21), and a less attractive face (d = 0.20). Higher mate value was related to being partnered, more upward-identifying, less upward-contrasting, and less downward-identifying strategies. Moreover, less downward-identifying was associated with higher mate value in survivors, but not controls; whereas greater downward-contrasting was associated with higher mate value among controls only (R 2  = 30.8%). Survivors do not generally view themselves as less valuable (potential) romantic partners, but they evaluate different characteristics either more positively or more negatively. Social comparison strategies offer targetable points of interventions to intervene on negative self-evaluations, potentially enhancing well-being.

Climate change is a major concern especially in view of the increasing global population and food security. Plant scientists need to look for genetic tools whose appropriate usage can contribute to sustainable food availability. G-proteins have been identified as some of the potential genetic tools that could be useful for protecting plants from various stresses. Heterotrimeric G-proteins consisting of three subunits Gα, Gβ and Gγ are important components of a number of signalling pathways. Their structure and functions are already well studied in animals but their potential in plants is now gaining attention for their role in stress tolerance. Earlier we have reported that over expressing pea Gβ conferred heat tolerance in tobacco plants. Here we report the interacting partners (proteins) of Gβ subunit of Pisum sativum and their putative role in stress and development. Out of 90 transformants isolated from the yeast-two-hybrid (Y2H) screening, seven were chosen for further investigation due to their recurrence in multiple experiments. These interacting partners were confirmed using β-galactosidase colony filter lift and ONPG (O-nitrophenyl-β-D-galactopyranoside) assays. These partners include thioredoxin H, histidine-containing phosphotransfer protein 5-like, pathogenesis-related protein, glucan endo-beta-1, 3-glucosidase (acidic isoform), glycine rich RNA binding protein, cold and drought-regulated protein (corA gene) and soluble inorganic pyrophosphatase 1. This study suggests the role of pea Gβ subunit in stress signal transduction and development pathways owing to its capability to interact with a wide range of proteins of multiple functions.

Architecture of the global land acquisition system: applying the tools of network science to identify key vulnerabilities

Seaquist, J. W.; Li Johansson, Emma; Nicholas, Kimberly A.

2014-11-01

Global land acquisitions, often dubbed ‘land grabbing’ are increasingly becoming drivers of land change. We use the tools of network science to describe the connectivity of the global acquisition system. We find that 126 countries participate in this form of global land trade. Importers are concentrated in the Global North, the emerging economies of Asia, and the Middle East, while exporters are confined to the Global South and Eastern Europe. A small handful of countries account for the majority of land acquisitions (particularly China, the UK, and the US), the cumulative distribution of which is best described by a power law. We also find that countries with many land trading partners play a disproportionately central role in providing connectivity across the network with the shortest trading path between any two countries traversing either China, the US, or the UK over a third of the time. The land acquisition network is characterized by very few trading cliques and therefore characterized by a low degree of preferential trading or regionalization. We also show that countries with many export partners trade land with countries with few import partners, and vice versa, meaning that less developed countries have a large array of export partnerships with developed countries, but very few import partnerships (dissassortative relationship). Finally, we find that the structure of the network is potentially prone to propagating crises (e.g., if importing countries become dependent on crops exported from their land trading partners). This network analysis approach can be used to quantitatively analyze and understand telecoupled systems as well as to anticipate and diagnose the potential effects of telecoupling.

Black and Latino gay, bisexual, and other men who have sex with men (MSM) have higher rates of HIV and other sexually transmitted infections (STIs) than their White counterparts. Differences in sexual networks have been hypothesized to play an important role in the observed racial/ethnic disparities in risk. However, concerns about the acceptability and feasibility of conducting sociocentric sexual network studies have left a dearth of data on the structure of sexual networks of MSM. If certain network research procedures are unacceptable among target populations, biases may be introduced. We conducted qualitative interviews and brief surveys with 30 self-identified Black (n = 12), Hispanic/Latino, (n = 9) and White (n = 9) sexually active MSM in the Greater Boston area to assess the acceptability and feasibility of potential procedures for a sociocentric sexual network study. We found that referring recent sexual partners as part of a sociocentric network study was generally acceptable, but racial/ethnic differences emerged regarding specific preferences for how to recruit sexual partners. While the majority of Black participants (7/12) explained that they would not want their name disclosed to sexual partners approached for study participation, most Latino participants (7/9) preferred having the opportunity to inform referrals themselves about the study prior to researchers contacting them, and White participants (8/9) favored having researchers disclose their names when recruiting referrals, emphasizing the importance of transparency. In order to reduce differential rates of research participation, increase scientific validity, and reduce risks of social harm, researchers studying sexual networks among MSM should be aware of these potential differences, engage communities in study design, and provide participants with a variety of options for recruiting their sexual partners.

Introduction Constructively engaging male partners in women-centred health programs such as family planning and prevention of mother-to-child HIV transmission has resulted in both improved health outcomes and stronger relationships. Concerted efforts to engage men in microbicide use could make it easier for women to access and use microbicides in the future. This paper synthesizes findings from studies that investigated men's role in their partners’ microbicide use during clinical trials to inform recommendations for male engagement in women's microbicide use. Methods We conducted primary and secondary analyses of data from six qualitative studies implemented in conjunction with microbicide clinical trials in South Africa, Kenya, and Tanzania. The analyses included data from 535 interviews and 107 focus groups with trial participants, male partners, and community members to answer research questions on partner communication about microbicides, men's role in women's microbicide use, and potential strategies for engaging men in future microbicide introduction. We synthesized the findings across the studies and developed recommendations. Results The majority of women in steady partnerships wanted agreement from their partners to use microbicides. Women used various strategies to obtain their agreement, including using the product for a while before telling their partners, giving men information gradually, and continuing to bring up microbicides until resistant partners acquiesced. Among men who were aware their partners were participating in a trial and using microbicides, involvement ranged from opposition to agreement/non-interference to active support. Both men and women expressed a desire for men to have access to information about microbicides and to be able to talk with a healthcare provider about microbicides. Conclusions We recommend counselling women on whether and how to involve their partners including strategies for gaining partner approval; providing couples’ counselling on microbicides so men have the opportunity to talk with providers; and targeting men with community education and mass media to increase their awareness and acceptance of microbicides. These strategies should be tested in microbicide trials, open-label studies, and demonstration projects to identify effective male engagement approaches to include in eventual microbicide introduction. Efforts to engage men must take care not to diminish women's agency to decide whether to use the product and inform their partners. PMID:25224618

To improve detection and quality of assessment of child and partner abuse within a health service. A formal organisational change approach was used to implement the New Zealand Family Violence Intervention Guidelines in a mid-sized regional health service. The approach includes obtaining senior management support, community collaboration, developing resources to support practice, research, evaluation and training. Formal pre-post evaluations were conducted of the training. Barriers and enablers of practice change were assessed through 85 interviews with 60 staff. More than 6000 clinical records were audited to assess rates of questioning for partner abuse. Identifications of partner abuse and referrals made were counted through the Family Violence Accessory File. Referrals to the Department of Child, Youth and Family Services (CYFS) were recorded routinely by the CYFS. Audits assessed quality of assessment of child and partner abuse, when identified. More than 700 staff were trained in dual assessment for child and partner abuse. Evaluations demonstrate improved confidence following training, though staff still need support. Barriers and enablers to asking about partner abuse were identified. Referrals from the health service to the CYFS increased from 10 per quarter to 70 per quarter. Identification of partner abuse increased from 30 to 80 per 6-month period. Routine questioning rates for partner abuse vary between services. Achieving and sustaining improved rates of identification and quality of assessment of child and partner abuse is possible with a formal organisational change approach.

Lung cancer patients and their spouses report high rates of distress. Due to the increasing popularity of and evidence for mindfulness-based interventions in cancer, mindfulness and self-compassion have been identified as potentially helpful skills when coping with cancer. This dyadic study examined how mindfulness and self-compassion are related to psychological distress and communication about cancer in couples facing lung cancer. Using the actor-partner interdependence model, self-reported mindfulness, self-compassion, psychological distress and communication about cancer were analyzed in a cross-sectional sample of 88 couples facing lung cancer. Regarding psychological distress, no difference was found between patients and spouses. In both partners, own levels of mindfulness ( B  = -0.19, p  = .002) and self-compassion ( B  = -0.45, p  < .001) were negatively related to own distress levels. At a dyadic level, own self-compassion was less strongly associated with distress if the partner reported high self-compassion ( B  = 0.03, p  = .049). Regarding communication about cancer, patients reported to communicate more openly with their partner than with spouses. However, after controlling for gender, this difference was no longer significant. In both partners, own self-compassion ( B  = 0.03, p  = .010) was significantly associated with own communication while mindfulness was not. A trend showed that mindfulness of the partner was related to more open communication in the individual ( B  = 0.01, p  = .080). These findings give a first indication that mindfulness and self-compassion skills may go beyond the individual and could impact couple functioning. Future research should examine whether couples facing (lung) cancer may benefit from programs in which mindfulness and self-compassion are cultivated.

Background Food access interventions are promising strategies for improving dietary intake, which is associated with better health. However, studies examining the relationship between food access and intake are limited to observational designs, indicating a need for more rigorous approaches. The Veggie Van (VV) program was a cluster-randomized intervention designed to address the gap between food access and intake. In this article, we aim to describe the approaches involved in recruiting community partners to participate in VV. Community Context The VV mobile market aimed to improve access to fresh fruits and vegetables by providing subsidized, high-quality, local produce in low-resource communities in North Carolina. This study describes the strategies and considerations involved in recruiting community partners and individual participants for participation in the VV program and evaluation. Methods To recruit partners, we used various strategies, including a site screener to identify potential partners, interest forms to gauge future VV use and prioritize enrollment of a high-need population, marketing materials to promote VV, site liaisons to coordinate community outreach, and a memorandum of understanding between all invested parties. Outcome A total of 53 community organizations and 725 participants were approached for recruitment. Ultimately, 12 sites and 201 participants were enrolled. Enrollment took 38 months, but our approaches helped successfully recruit a low-income, low-access population. The process took longer than anticipated, and funding constraints prevented certain strategies from being implemented. Interpretation Recruiting community partners and members for participation in a multi-level, community-based intervention was challenging. Strategies and lessons learned can inform future studies.

Because of the dearth of available partners, older women looking to date may have to relax their dating standards to find a dating partner, perhaps accepting a life situation that is not what they had hoped for. However older women may be reluctant to sacrifice an often recently-gained lifestyle free of caregiving obligations. Older men, on the other hand, have a large pool of potential dating partners and do not face the same dilemma. We compared Internet dating profiles for 100 older adults and 100 younger adults, and found that older adults (and especially older women) were more selective than younger adults when it came to the age, race, religion, income, and height of a prospective dating partner. However, older adults were willing to travel substantially farther than younger adults to meet the right partner. These findings paint a clear picture of older Internet daters as eager to meet the right person, but not desperate to meet just anyone.

Heme is an essential cofactor for most organisms and all metazoans. While the individual enzymes involved in synthesis and utilization of heme are fairly well known, less is known about the intracellular trafficking of porphyrins and heme, or regulation of heme biosynthesis via protein complexes. To better understand this process we have undertaken a study of macromolecular assemblies associated with heme synthesis. Herein we have utilized mass spectrometry with coimmunoprecipitation of tagged enzymes of the heme biosynthetic pathway in a developing erythroid cell culture model to identify putative protein partners. The validity of these data obtained in the tagged protein system is confirmed by normal porphyrin/heme production by the engineered cells. Data obtained are consistent with the presence of a mitochondrial heme metabolism complex which minimally consists of ferrochelatase, protoporphyrinogen oxidase and aminolevulinic acid synthase-2. Additional proteins involved in iron and intermediary metabolism as well as mitochondrial transporters were identified as potential partners in this complex. The data are consistent with the known location of protein components and support a model of transient protein-protein interactions within a dynamic protein complex. PMID:26287972

Little is known about intimate partner violence (IPV) victims' situational risk recognition, defined as the ability to identify situational factors that signal imminent risk of victimization. Using semi-structured interviews, qualitative data were collected from a community sample of 31 female victims of IPV episodes involving substance use. Thirteen themes were identified, the most prevalent being related to the partner's verbal behavior, tone of voice, motor behavior, alcohol or drug use, and facial expression. Participants reporting at least some anticipation of physical aggression (61.3% of the sample) tended to identify multiple factors (M = 3.47), suggesting numerous situational features often contribute to situational risk recognition. © The Author(s) 2015.

Assessing the potential impact of artemisinin and partner drug resistance in sub-Saharan Africa.

Artemisinin and partner drug resistant malaria parasites have emerged in Southeast Asia. If resistance were to emerge in Africa it could have a devastating impact on malaria-related morbidity and mortality. This study estimates the potential impact of artemisinin and partner drug resistance on disease burden in Africa if it were to emerge. Using data from Asia and Africa, five possible artemisinin and partner drug resistance scenarios are characterized. An individual-based malaria transmission model is used to estimate the impact of each resistance scenario on clinical incidence and parasite prevalence across Africa. Artemisinin resistance is characterized by slow parasite clearance and partner drug resistance is associated with late clinical failure or late parasitological failure. Scenarios with high levels of recrudescent infections resulted in far greater increases in clinical incidence compared to scenarios with high levels of slow parasite clearance. Across Africa, it is estimated that artemisinin and partner drug resistance at levels similar to those observed in Oddar Meanchey province in Cambodia could result in an additional 78 million cases over a 5 year period, a 7% increase in cases compared to a scenario with no resistance. A scenario with high levels of slow clearance but no recrudescence resulted in an additional 10 million additional cases over the same period. Artemisinin resistance is potentially a more pressing concern than partner drug resistance due to the lack of viable alternatives. However, it is predicted that a failing partner drug will result in greater increases in malaria cases and morbidity than would be observed from artemisinin resistance only.

This study examined the attribution of mild cognitive impairment (MCI) etiology assigned by individuals with MCI and their care partners, and the extent to which the dyads agreed on the attribution of MCI etiology. We conducted secondary analyses of cross-sectional data from a cohort of individuals with MCI (n = 60) and their care partners (n = 60). The mean age of the individuals with MCI was 71.0 ± 9.4 years and of care partners 64.2 ± 11.0 years. The primary outcome was attribution assigned to memory deficits on the Illness Perception Questionnaire. We categorized the attribution of MCI etiology as either potentially controllable or uncontrollable factors. We described the distribution of MCI etiology with descriptive and contingency tables. We determined the odds of a patient or care partner choosing one type of MCI etiology over another. Although individuals with MCI and their care partners most frequently attributed MCI to uncontrollable factors (81.7% and 61.0%, respectively), care partners were 28.41 (95% CI, 1.26 to 645.48) times more likely to attribute MCI etiology to potentially controllable factors than individuals with MCI. No significant associations between demographic factors and attribution of MCI etiology were found for the individuals with MCI or the care partners. Findings demonstrated that members of the dyad attributed MCI etiology to different causes. Attributions of MCI etiology should be explored by professionals to clarify misconceptions and potentially improve subsequent voluntary actions intended to assist oneself or others.

This study investigated effects of employed and unemployed job status on health outcomes with questionnaires in 50 young couples. Analysis of variance revealed higher pessimism, higher stress levels, and lower life satisfaction in couples in which one partner was unemployed. These couples also exhibited more health risk behaviours compared to couples in which both partners were working. The dyadic analysis of data, using an actor-partner interdependence model, demonstrated strong actor and partner effects for male partner's job status. Being unemployed was significantly associated not only with male partner's life satisfaction but also with the life satisfaction of his female partner. In addition, male partner's pessimism was identified as a significant variable which mediates between male partner's job status and female partner's life satisfaction. The study highlights the relevance of the accomplishment of tasks in the domains of work and partnership during young adulthood and it emphasises the gender specific importance.

Is love colorblind? Political orientation and interracial romantic desire.

The present research examined the association of political orientation with ingroup favoritism in two live romantic contexts. In Study 1, White participants had sequential interactions with both a White and Black confederate and reported their romantic desire for each. In Study 2, both White and Black participants speed-dated multiple potential romantic partners and reported whether they would be interested in meeting each speed-dating partner again. In both studies, White participants' political conservatism positively predicted the strength of the ingroup-favoring bias: White conservatives were less likely than White liberals to desire Black (interracial) relative to White potential romantic partners. In contrast, Black participants' political conservatism negatively predicted the strength of the ingroup-favoring bias: Consistent with system-justification theory, Black conservatives were more likely than Black liberals to desire White (interracial) relative to Black potential romantic partners. Political orientation may be a key factor that influences the initiation of interracial romantic relationships.

Mate-choice copying occurs when animals rely on the mating choices of others to inform their own mating decisions. The proximate mechanisms underlying mate-choice copying remain unknown. To address this question, we tracked the gaze of men and women as they viewed a series of photographs in which a potential mate was pictured beside an opposite-sex partner; the participants then indicated their willingness to engage in a long-term relationship with each potential mate. We found that both men and women expressed more interest in engaging in a relationship with a potential mate if that mate was paired with an attractive partner. Men and women's attention to partners varied with partner attractiveness and this gaze attraction influenced their subsequent mate choices. These results highlight the prevalence of non-independent mate choice in humans and implicate social attention and reward circuitry in these decisions. PMID:20161739

Objectives To find the fit that is most apt for the current situation in Korea and to find new ways of identifying potential partners for the purpose of public–private partnership (PPP). The research was conducted using domestic and international literature where the concept and definition of PPP was stated, and cases of PPP reported by the World Health Organization and cases in developed countries were investigated. Materials and methods Data were collected from 237 PPP potential partner organization, government agencies, and the government under a special law, local governments, businesses, hospitals, and private organizations through their internet webpage. The Delphi questionnaire was given to relevant institutions and questionnaire was surveyed general hospitals. Results Groups that were likely to realize most of the partnership were nonprofit or nongovernmental organizations, the central government, the private sector, public healthcare services, and products. Conclusion In order to secure the position of exceptional comparative advantage of international expertise in the field of healthcare, we must implement PPP strategy that is in ordinance of domestic situation.

2017-04-01

This study examined the relationships of HIV/AIDS beliefs, self-efficacy for AIDS preventive behaviors, perception of HIV as a chronic disease, and HIV risk behaviors among young Thai men who have sex with men. Participants were recruited for a self-administered anonymous survey through Facebook. Logistic regression analysis was used to identify factors associated with each of four HIV risk behavior outcomes. Factors associated with sexual risk behaviors included age (18 and 21 years), having a current regular male partner, self-efficacy for AIDS preventive behaviors (self-efficacy in refusing sexual intercourse, self-efficacy in questioning potential sex partners, and self-efficacy in condom use), AIDS health belief (perceived susceptibility to HIV/AIDS, perceived severity of HIV/AIDS, perceived barriers to condom use, and cues to action for HIV/AIDS prevention), and perception of HIV/AIDS as a chronic disease (perceived HIV sero-status disclosure). Knowledge generated from this study has the potential to inform prevention messages for young Thai MSM.

The value of physical attractiveness in romantic partners: modeling biological and social variables.

PubMed

Jonason, Peter K

2009-04-01

According to research on physical attractiveness, personal attributes such as gender, height, and self-perception are important in determining how much individuals value physical attractiveness in their romantic partners. In a survey of 228 college-aged participants, the ratings of the physical attractiveness of potential romantic partners were positively correlated with how much participants valued physical attractiveness in their long-term romantic partners. Individuals' partner preferences may be sensitive to their perceptions of themselves. Perceptions of the attractiveness of those in one's local area may also play a part in the development of such partner preferences through exposure.

The rapidly evolving American health system creates economic and societal incentives for public and private health organizations to collaborate. Despite the apparent benefits of collaboration, there is a paucity of information available to help local agencies develop partnerships. This study, itself a collaboration between a school of public health (SPH) and a Georgia health district, was undertaken to identify critical factors necessary to successfully initiate and sustain a public/private community health collaboration. Professional staff at the SPH conducted 26 standardized interviews involving participants from Cobb and Douglas counties Boards of Health; Promina Northwest (now known as Wellstar), a not-for-profit health system; and community stakeholders. Content analysis of each interview question was performed and comparisons were made both within each group and across groups. Trends were identified in the following key areas: vision of health care for Cobb and Douglas counties, forces driving collaboration, strengths of each organization, critical negotiating issues, and potential community gain resulting from the partnership. A shared vision between potential collaborators facilitates communication regarding strategies to achieve common goals. A previous history of working together in limited capacities allowed the partners to develop trust and respect for one another prior to entering negotiations. These factors, when taken in conjunction with each organization's strong leadership and knowledge of the community, build a strong foundation for a successful partnership.

Background Persistent high levels of sexually transmitted infection (STI) in Madagascar indicate current prevention strategies are inadequate. STI/HIV prevention based in social venues may play an important role in reaching individuals at risk of infection. We identified venues where people meet sexual partners and measured the need and potential for venue-based prevention. Methods Interviews were conducted in 7 Madagascar towns with 1) community informants to identify social venues, 2) individuals socializing at a sample of venues to assess sexual behavior among venue patrons, and 3) venue representatives to assess the potential for venue-based intervention. Results Community informants identified numerous venues (range: 67–211 venues, depending on the town); streets, bars, and hotels were most commonly reported. Among 2982 individuals socializing at venues, 78% of men and 74% of women reported new sexual partnership or sex trade for money, goods, or services in the past 4 weeks and 19% of men and 18% of women reported symptoms suggestive of STI in the past 4 weeks. STI symptom levels were disproportionately high among respondents reporting either sex trade or new sexual partnership in the past 4 weeks. Twenty-eight percent of men and 41% of women reported condom use during the last sex act with a new partner. Although 24% to 45% of venues had hosted STI/HIV interventions, interventions were deemed possible at 73% to 90% venues according to 644 interviews with venue representatives. Conclusions Venue-based intervention is possible and would reach a spectrum of populations vulnerable to STI/HIV including sex workers, their clients, and other high-risk populations. PMID:18496471

HIV is spreading among Chinese MSM and may possibly lead to infection of female partner. Pressure to marry may drive a greater proportion of Chinese MSM to have female partners than MSM elsewhere in the world. Measurement of the size of the potential risk to female partners of Chinese MSM is inconsistent in literature. From samples of MSM in two Chinese cities, we documented numbers of sexual partners and sexual activity with those partners. About 500 MSM were sampled in each city. 11.0% and 12.6% of men reported having any female partners in the past six months in Chongqing and Beijing, respectively. Men also reported that only 7.3% and 6.7% of their entire partnerships were with women in Chongqing and Beijing, respectively. Defining transmission risk accounting for receptive anal sex among men and condom non-use with both male and female partners 3.4% of MSM in both Chongqing and Beijing would have the potential to transmit HIV to female partners. Only 9 (1.8%) men in Chongqing and 2 (0.4%) in Beijing were HIV-positive and also had unprotected intercourse with females. The majority of HIV transmission risk among MSM in China is not from MSM to females. PMID:23666182

At least half a million women are victims of intimate partner violence in the United States annually, resulting in substantial harm. However, the etiology of violence to intimate partners is not well understood. Witnessing such violence in childhood has been proposed as a principal cause of adulthood perpetration, yet it remains unknown whether the association between witnessing intimate partner violence and adulthood perpetration is causal. We conducted a propensity-score analysis of intimate partner violence perpetration to determine whether childhood witnessing is associated with perpetration in adulthood, independent of a wide range of potential confounding variables, and therefore might be a causal factor. We used data from 14,564 U.S. men ages 20 and older from the 2004-2005 wave of the National Epidemiologic Survey on Alcohol and Related Conditions. Nearly 4% of men reported violent behavior toward an intimate partner in the past year. In unadjusted models, we found a strong association between childhood witnessing of intimate partner violence and adulthood perpetration (for witnessing any intimate partner violence, risk ratio [RR] = 2.6 [95% confidence interval = 2.1-3.2]; for witnessing frequent or serious violence, 3.0 [2.3-3.9]). In propensity-score models, the association was substantially attenuated (for witnessing any intimate partner violence, adjusted RR = 1.6 [1.2-2.0]; for witnessing frequent or serious violence, 1.6 [1.2-2.3]). Men who witness intimate partner violence in childhood are more likely to commit such acts in adulthood, compared with men who are otherwise similar with respect to a large range of potential confounders. Etiological models of intimate partner violence perpetration should consider a constellation of childhood factors.

Background Community engagement and rigorous science are necessary to address health issues. Increasingly, community health organizations are asked to partner in research. To strengthen such community organization–academic partnerships, increase research capacity in community organizations, and facilitate equitable partnered research, the Partners in Education Evaluation and Research (PEER) program was developed. The program implements an 18-month structured research curriculum for one mid-level employee of a health-focused community-based organization with an organizational mentor and a Case Western Reserve University faculty member as partners. Methods The PEER program was developed and guided by a community–academic advisory committee and was designed to impact the research capacity of organizations through didactic modules and partnered research in the experiential phase. Active participation of community organizations and faculty during all phases of the program provided for bidirectional learning and understanding of the challenges of community-engaged health research. The pilot program evaluation used qualitative and quantitative data collection techniques, including experiences of the participants assessed through surveys, formal group and individual interviews, phone calls, and discussions. Statistical analysis of the change in fellows’ pre-test and post-test survey scores were conducted using paired sample t tests. The small sample size is recognized by the authors as a limitation of the evaluation methods and would potentially be resolved by including more cohort data as the program progresses. Qualitative data were reviewed by two program staff using content and narrative analysis to identify themes, describe and assess group phenomena and determine program improvements. Objectives The objective of PEER is to create equitable partnerships between community organizations and academic partners to further research capacity in said organizations and develop mutually beneficial research partnerships between academia and community organizations. Conclusion PEER demonstrates a commitment to successfully developing sustainable research capacity growth in community organizations, and improved partnered research with academic institutions.

Chlamydia prevalence in the Netherlands remains high despite targeted efforts. Effective Partner Notification (PN) and Partner Treatment (PT) can interrupt transmission and prevent re-infections. Patient Initiated Partner Treatment (PIPT) may strengthen chlamydia control. This study explores the current practice of PN and PT, and benefits of, and barriers and facilitators for PIPT among professionals in sexual health care in the Netherlands. A qualitative study was performed among GPs, GP-assistants (GPAs), physicians and nurses working at Sexual Health Clinics (SHC) and key-informants on ethnical diversity using topic lists in focus groups (N = 40) and semi-structured questionnaires in individual interviews (N = 9). Topics included current practices regarding PN and PT, attitude regarding PIPT, and perceived barriers and facilitators for PIPT. Interviews were taped, transcribed verbatim, and coded using ATLAS.ti. A quantitative online questionnaire on the same topics was sent to all physicians and nurses employed at Dutch SHC (complete response rate 26% (84/321)). The qualitative study showed that all professionals support the need for more attention to PN, and that they saw advantages in PIPT. Mentioned barriers included unwilling PN-behaviour, Dutch legislation, several medical considerations and inadequate skills of GPs. Also, concerns about limited knowledge of cultural sensitivity around PN and PT were raised. Mentioned facilitators of PIPT were reliable home based test-kits, phone-contact between professionals and notified partners, more consultation time for GPs or GPAs and additional training. The online questionnaire showed that SHC employees agreed that partners should be treated as soon as possible, but also that they were reluctant towards PIPT without counselling and testing. Professionals saw advantages in PIPT, but they also identified barriers hampering the potential introduction of PIPT. Improving PN and counselling skills with specific focus on cultural sensitivity is needed. PIPT could be considered for specific partners. PIPT in combination with home based testing and using e-healthcare should be further explored and developed.

Community-based participatory research (CBPR) is an orientation to research that places value on equitable collaborations between community members and academic partners, reflecting shared decision making throughout the research process. Although CBPR has become increasingly popular for research with adults, youth are less likely to be included as partners. In our review of the literature, we identified 399 articles described by author or MeSH keyword as CBPR related to youth. We analyzed each study to determine youth engagement. Not including misclassified articles, 27 % of percent of studies were community-placed but lacked a community partnership and/or participatory component. Only 56 (15 %) partnered with youth in some phase of the research process. Although youth were most commonly involved in identifying research questions/priorities and in designing/conducting research, most youth-partnered projects included children or adolescents in several phases of the research process. We outline content, methodology, phases of youth partnership, and age of participating youth in each CBPR with youth project, provide exemplars of CBPR with youth, and discuss the state of the youth-partnered research literature.

Identifying venues where women meet sexual partners, particular partners who increase women's risk of acquiring HIV, could inform prevention efforts. We categorized venues where women enrolled in HPTN 064 reported meeting their last three sex partners as: (1) Formal, (2) Public, (3) Private, and (4) Virtual spaces. We used multinomial logistic regression to assess the association between these venues and women's individual characteristics and reports of their partners' HIV risk characteristics. The 2099 women reported meeting 3991 partners, 51 % at Public, 30 % Private, 17 % Formal and 3 % at Virtual venues. Women meeting partners at Formal venues reported more education and condom use than women meeting partners at other venues. Fewer partners met through Formal venues had "high" risk characteristics for HIV than through other venues and hence may pose less risk of HIV transmission. HIV prevention interventions can help women choose partners with fewer risk characteristics across all venue types.

Identifying hidden sexual bridging communities in Chicago.

2009-07-01

Bridge populations can play a central role in the spread of human immunodeficiency virus (HIV) by providing transmission links between higher and lower prevalence populations. While social network methods are well suited to the study of bridge populations, analyses tend to focus on dyads (i.e., risk between drug and/or sex partners) and ignore bridges between distinct subpopulations. This study takes initial steps toward moving the analysis of sexual network linkages beyond individual and risk group levels to a community level in which Chicago's 77 community areas are examined as subpopulations for the purpose of identifying potential bridging communities. Of particular interest are "hidden" bridging communities; that is, areas with above-average levels of sexual ties with other areas but whose below-average AIDS prevalence may hide their potential importance for HIV prevention. Data for this analysis came from the first wave of recruiting at the Chicago Sexual Acquisition and Transmission of HIV Cooperative Agreement Program site. Between August 2005 through October 2006, respondent-driven sampling was used to recruit users of heroin, cocaine, or methamphetamine, men who have sex with men regardless of drug use, the sex partners of these two groups, and sex partners of the sex partners. In this cross-sectional study of the sexual transmission of HIV, participants completed a network-focused computer-assisted self-administered interview, which included questions about the geographic locations of sexual contacts with up to six recent partners. Bridging scores for each area were determined using a matrix representing Chicago's 77 community areas and were assessed using two measures: non-redundant ties and flow betweenness. Bridging measures and acquired immunodeficiency syndrome (AIDS) case prevalence rates were plotted for each community area on charts representing four conditions: below-average bridging and AIDS prevalence, below-average bridging and above-average AIDS prevalence, above-average bridging and AIDS prevalence, and above-average bridging and below-average AIDS prevalence (hidden bridgers). The majority of the 1,068 study participants were male (63%), African American (74%), and very poor, and the median age was 44 years. Most (85%) were sexually active, and 725 provided useable geographic information regarding 1,420 sexual partnerships that involved 57 Chicago community areas. Eight community areas met or came close to meeting the definition of hidden bridgers. Six areas were near the city's periphery, and all eight areas likely had high inflows or outflows of low-income persons displaced by gentrification. The results suggest that further research on this method is warranted, and we propose a means for public health officials in other cities to duplicate the analysis.

Exploring Risk and Protective Factors for Recent and Past Intimate Partner Violence Against New Zealand Women.

Fanslow, Janet; Gulliver, Pauline

2015-01-01

The purpose of this investigation was to identify risk and protective factors associated with intimate partner violence (IPV) in a high-income country (New Zealand) and to identify those factors that distinguish between current versus previous exposure to IPV. Data were drawn from the New Zealand replication of the World Health Organization's Multi-Country Study on Women's Health and Domestic Violence. Logistic regression was conducted to identify those variables associated with experience of IPV. Problem drinking, a partner who has concurrent sexual relationships, and a partner who is violent outside the home were associated with increased likelihood of current as opposed to previous experience of IPV. Increased household income and both the respondent and her partner being employed were associated with reduced likelihood that women would experience current as opposed to prior IPV. The findings point toward the need for comprehensive approaches to reduce all forms of violence and to contribute to the primary prevention of IPV. Strategies that address early exposure to violence, problematic alcohol consumption, gender transformative approaches to working with boys and men, and economic empowerment for women may all hold promise.

To identify the predominant species and the role of sexual partners in the maintenance of recurrent vulvovaginitis by Candida spp. A prospective study of 830 patients aged 18 to 65 years with yeast vaginitis was performed between August 2007 and March 2012. Patients with diabetes mellitus, AIDS or taking corticosteroids, antibiotics or hormone therapy and immunosuppressed patients, patients using vaginal douches, spermicides or intrauterine devices were excluded from the study. Candida species were identified by phenotypic and genotypic methods. The chi-square test was used to correlate the presence of Candida spp. in male partners with the recurrence of vaginitis. The fungal agent was isolated from a total of 40 women, 24 with recurrent vaginitis and from 15 of their sexual partners, 10 of whom were asymptomatic while 5 were symptomatic. There was agreement of the species found in the couple in 100% of recurrences. C. albicans (62.4 and 60%), C. glabrata (29.1 and 33.3%) and C. guilliermondii species were identified. Candida tropicalis (4.1%) was isolated from only one patient. Candida albicans was isolated from the remaining 16 women who had uncomplicated vaginitis. C. glabrata was isolated from only two of the asymptomatic partners. There was a predominance of C. albicans and symptomatic or asymptomatic partners can play an important role as a reservoir and source of transmission of yeast, especially in cases of recurrent vulvovaginitis.

People are sensitive to facial attractiveness because it is an important biological and social signal. As such, our perceptual and attentional system seems biased toward attractive faces. We tested whether attractive faces capture attention and enhance memory access in an involuntary manner using a dual-task rapid serial visual presentation (dtRSVP) paradigm, wherein multiple faces were successively presented for 120 ms. In Experiment 1, participants (N = 26) were required to identify two female faces embedded in a stream of animal faces as distractors. The results revealed that identification of the second female target (T2) was better when it was attractive compared to neutral or unattractive. In Experiment 2, we investigated whether perceived attractiveness affects T2 identification (N = 27). To this end, we performed another dtRSVP task involving participants in a romantic partnership with the opposite sex, wherein T2 was their romantic partner's face. The results demonstrated that a romantic partner's face was correctly identified more often than was the face of a friend or unknown person. Furthermore, the greater the intensity of passionate love participants felt for their partner (as measured by the Passionate Love Scale), the more often they correctly identified their partner's face. Our experiments indicate that attractive and romantic partners' faces facilitate the identification of the faces in an involuntary manner.

Porcine reproductive and respiratory syndrome virus (PRRSV) is an Arterivirus that has heavily impacted the global swine industry. The PRRSV nonstructural protein 2 (nsp2) plays crucial roles in viral replication and host immune regulation, most likely by interacting with viral or cellular proteins that have not yet been identified. In this study, a quantitative interactome approach based on immunoprecipitation and stable isotope labeling with amino acids in cell culture (SILAC) was performed to identify nsp2-interacting proteins in PRRSV-infected cells with an nsp2-specific monoclonal antibody. Nine viral proteins and 62 cellular proteins were identified as potential nsp2-interacting partners. Our data demonstrate that the PRRSV nsp1α, nsp1β, and nucleocapsid proteins all interact directly with nsp2. Nsp2-interacting cellular proteins were classified into different functional groups and an interactome network of nsp2 was generated. Interestingly, cellular vimentin, a known receptor for PRRSV, forms a complex with nsp2 by using viral nucleocapsid protein as an intermediate. Taken together, the nsp2 interactome under the condition of virus infection clarifies a role of nsp2 in PRRSV replication and immune evasion. Viral proteins must interact with other virus-encoded proteins and/or host cellular proteins to function, and interactome analysis is an ideal approach for identifying such interacting proteins. In this study, we used the quantitative interactome methodology to identify the viral and cellular proteins that potentially interact with the nonstructural protein 2 (nsp2) of porcine reproductive and respiratory syndrome virus (PRRSV) under virus infection conditions, thus providing a rich source of potential viral and cellular interaction partners for PRRSV nsp2. Based on the interactome data, we further demonstrated that PRRSV nsp2 and nucleocapsid protein together with cellular vimentin, form a complex that may be essential for viral attachment and replication, which partly explains the role of nsp2 in PRRSV replication and immune evasion.

Previously, we identified the stress-induced chaperone, Hsp27, as highly overexpressed in castration-resistant prostate cancer and developed an Hsp27 inhibitor (OGX-427) currently tested in phase I/II clinical trials as a chemosensitizing agent in different cancers. To better understand the Hsp27 poorly-defined cytoprotective functions in cancers and increase the OGX-427 pharmacological safety, we established the Hsp27-protein interaction network using a yeast two-hybrid approach and identified 226 interaction partners. As an example, we showed that targeting Hsp27 interaction with TCTP, a partner protein identified in our screen increases therapy sensitivity, opening a new promising field of research for therapeutic approaches that could decrease or abolish toxicity for normal cells. Results of an in-depth bioinformatics network analysis allying the Hsp27 interaction map into the human interactome underlined the multifunctional character of this protein. We identified interactions of Hsp27 with proteins involved in eight well known functions previously related to Hsp27 and uncovered 17 potential new ones, such as DNA repair and RNA splicing. Validation of Hsp27 involvement in both processes in human prostate cancer cells supports our system biology-predicted functions and provides new insights into Hsp27 roles in cancer cells. © 2014 by The American Society for Biochemistry and Molecular Biology, Inc.

The current research reports a dyadic analysis of sexual satisfaction, relationship happiness, and correlates of these couple outcomes in a large multinational dataset consisting of 1,009 midlife heterosexual couples (2,018 individuals) recruited in Japan, Brazil, Germany, Spain, and the United States (Heiman et al., 2011). Actor-Partner Interdependence Models (Kenny, Kashy, & Cook, 2006) identified correlates of sexual satisfaction that included individuals' reports of good health; frequent kissing, cuddling, and caressing; frequent recent sexual activity; attaching importance to one's own and one's partner's orgasm; better sexual functioning; and greater relationship happiness. Even after controlling for individual-level effects, partners' reports of good health; frequent kissing, cuddling, and caressing; frequent recent sexual activity; attaching importance to one's own and one's partner's orgasm; better sexual functioning; and greater relationship happiness contributed significantly to predicting and understanding individuals' sexual satisfaction. Correlates of relationship happiness included individuals' reports of good health; frequent kissing, cuddling, and caressing; frequent recent sexual activity; attaching importance to one's own and one's partner's orgasm; better sexual functioning; and greater sexual satisfaction, and once again, even after controlling for individual-level effects, partners' reports of each of these correlates contributed significantly to predicting and understanding individuals' relationship happiness. Interactions of individual and partner effects with participant gender are also reported. Current results demonstrate empirically that the partner "matters" to an individual's sexual satisfaction and relationship happiness and indicate that a comprehensive understanding of factors contributing to these couple outcomes requires a couple-level research strategy. Partner effects, even when controlling for individual effects, were consistently observed, and explanation of sexual satisfaction and relationship happiness always depended on identifying and understanding mutual and concurrent individual and partner influences.

Purpose Study goals were to (a) understand the attitudes of employees in low-wage industries toward workplace health promotion, including views on appropriateness of employer involvement in employee health, and level of interest in workplace health promotion overall and in specific programs; and (b) determine the potential for extending workplace health promotion to spouses and partners of these employees. Approach Forty-two 60-90-minute interviews Setting Interviews were conducted with couples (married or living together) in the Seattle/King County metropolitan area of Washington State. Participants Forty-two couples with one or more members working in one of five low-wage industries: accommodation/food services, education, health care/social assistance, manufacturing, and retail trade. Method Qualitative analysis of interview transcripts using grounded theory to identify themes. Results Employees consider workplace health promotion both appropriate and desirable, and believe it benefits employers through increased productivity and morale. Most have little personal experience with it and doubt their employers would prioritize employee health. Employees are most interested in efforts focused on nutrition and physical activity. Both employees and their partners support extending workplace health promotion to include partners. Conclusion Employees and their partners are interested in workplace health promotion if it addresses behaviors they care about. Concern over employer involvement in their personal health decisions is minimal; instead, employees view employer interest in their health as a sign that they are valued. PMID:25162321

Maternal smoking is one of the most modifiable factors with clear adverse effects for the fetus and the entire family. Addressing the dearth of pregnancy smoking interventions with partner support, PRISM (Prevent Relapse In SMoking) is a partnership between a research institution and the two largest state-owned obstetrics and gynecology clinics in Cluj-Napoca, Romania. The study will assess the efficacy of a couple-focused telephone-counseling program to prevent smoking relapse among mothers who quit smoking closely before or during pregnancy. The intervention is a program for couples based on motivational interviewing delivered over the phone after birth. The study is an ongoing randomized controlled trial of 250 Romanian women recruited soon after childbirth, who quit smoking in the six months before pregnancy or no later than the end of the first pregnancy trimester and remained abstinent (which was biochemically verified) until delivery. Participants were randomized to: (1) a control arm (usual care); and (2) an intervention arm consisting of up to 4 postnatal counseling calls for mothers and their partners using motivational interviewing to encourage the woman to remain smoke-free and the partner to support her decision. The primary outcome is maternal smoking abstinence at 6 months postpartum (biochemically verified). PRISM has the potential to identify strategies to reduce maternal postnatal relapse and increase partner quitting. If successful, the program may be an effective method to prevent and reduce smoking, which may lead to improved child, mother, and partner health both in the short and the long term.

The purpose of this study was to explore variations in demographics, culture, self-esteem, and intimate partner violence among Hispanic women according to birthplace, and to identify factors associated with these differences in intimate partner violence (IPV). Baseline data from a randomized control trial testing the efficacy of an HIV prevention program were used. Path analyses identified differences in IPV between Colombian women and women from other Central/South American countries. Self-esteem was the only factor associated with these differences. Interventions addressing the unique needs of Hispanic women from different subgroups are needed.

Meta-Ethnography of Qualitative Research on the Experience of Being a Partner to an Individual with Schizophrenia Spectrum Disorder.

Several qualitative studies explore the experience of being a partner to an individual with schizophrenia spectrum disorder, but these studies remain isolated "islands of knowledge." This meta-ethnography aimed to synthesize current qualitative studies using Noblit and Hare's method. Thirteen studies were identified for inclusion. Three overarching themes were revealed: unmet expectations of relationship, renegotiating relationship roles, and separation versus togetherness. Themes interacted as a cycle with separation versus togetherness as temporal endpoints. Partners also renegotiated relationships with mental health professionals to accommodate unmet expectations. Leverage points for intervention were identified.

Nigeria has the second highest number of new HIV infections annually. Therefore, it is important to explore new strategies for preventing new infections. The introduction of pre-exposure prophylaxis (PrEP) for use by persons at high risk of HIV infection has new potential in preventing new HIV infections. The aim of this study is to explore the public opinion, community interest, and perceptions about the use and access to PrEP in Nigeria. This formative study used a mixed method approach to collect data on public opinions and perceptions on appropriate target groups for PrEP access, community interest, perceptions about the use of PrEP as an HIV-prevention tool, how best to communicate with participants about PrEP, concerns about PrEP use by serodiscordant couples, and suggestions for the design and implementation of a PrEP demonstration project. Telephone and in-depth interviews were conducted, and focus group discussions and consultative meetings were held with critical stakeholders engaged in HIV-prevention, treatment, care, and support programmes in Nigeria. An online survey was also conducted. HIV serodiscordant couples were identified as the appropriate target group for PrEP use. Most respondents felt that PrEP use by key affected populations would help reduce the HIV incidence. Stigma was identified as a major concern and a potential barrier for the acceptance and use of PrEP by HIV serodiscordant couples. Electronic and print media were identified as important means for massive public education to prevent stigma and create awareness about PrEP. In a male dominated society such as Nigeria, HIV-negative male partners in serodiscordant relationships may resist enrolment in PrEP programmes. This may be complicated by the fact that the identified index partner in most serodiscordant relationships in Nigeria is an HIV-positive woman, who is often diagnosed during pregnancy. PrEP uptake and use by HIV serodiscordant couples in Nigeria may face notable but surmountable challenges. Much depends on the appropriateness of actions taken by multiple players. Motivation of HIV-negative male partners to use PrEP and establishment of effective public education programmes in addressing stigma are essential.

Clerodane diterpenoids are a class of naturally occurring molecules widely distributed in the Lamiaceae family. Neo-clerodane diterpenoids from Salvia ssp were recently described as compounds inhibiting the proliferation of human cancer cell lines. To gain new insights into molecular mechanism(s) underlying the antitumor potential of this class of compounds, we used a chemical proteomics approach to analyse the cellular interactome of hardwickiic acid (HAA) selected as a representative molecule. HAA was linked to an opportune 1,1'-carbonyldiimidazole modified by 1,12-dodecanediamine and then immobilized on a matrix support. The modified beads were then used as bait for fishing the potential partners of HAA in a U937 cell lysate. We identified heat shock protein 27 (Hsp27), an ATP-independent antiapoptotic chaperone characterized for its tumorigenic and metastatic properties and now referenced as a major therapeutic target in many types of cancer, as a major HAA partner. Here, we also report the study of HAA-Hsp27 interaction by means of a panel of chemical and biological approaches, including surface plasmon resonance measurements limited proteolysis, and biochemical assays. Our data suggest that HAA could provide a potential tool to develop strategies for the discovery of Hsp27 chemical inhibitors.

The purpose of this study is to characterize the potential benefits and challenges of electronic informed consent (eIC) as a strategy for rapidly expanding the reach of large biobanks while reducing costs and potentially enhancing participant engagement. The Partners HealthCare Biobank (Partners Biobank) implemented eIC tools and processes to complement traditional recruitment strategies in June 2014. Since then, the Partners Biobank has rigorously collected and tracked a variety of metrics relating to this novel recruitment method. From June 2014 through January 2016, the Partners Biobank sent email invitations to 184,387 patients at Massachusetts General Hospital and Brigham and Women’s Hospital. During the same time period, 7078 patients provided their consent via eIC. The rate of consent of emailed patients was 3.5%, and the rate of consent of patients who log into the eIC website at Partners Biobank was 30%. Banking of biospecimens linked to electronic health records has become a critical element of genomic research and a foundation for the NIH’s Precision Medicine Initiative (PMI). eIC is a feasible and potentially game-changing strategy for these large research studies that depend on patient recruitment.

Understanding the computations that take place in brain circuits requires identifying how neurons in those circuits are connected to one another. We describe a technique called TRACT (TRAnsneuronal Control of Transcription) based on ligand-induced intramembrane proteolysis to reveal monosynaptic connections arising from genetically labeled neurons of interest. In this strategy, neurons expressing an artificial ligand (‘donor’ neurons) bind to and activate a genetically-engineered artificial receptor on their synaptic partners (‘receiver’ neurons). Upon ligand-receptor binding at synapses the receptor is cleaved in its transmembrane domain and releases a protein fragment that activates transcription in the synaptic partners. Using TRACT in Drosophila we have confirmed the connectivity between olfactory receptor neurons and their postsynaptic targets, and have discovered potential new connections between neurons in the circadian circuit. Our results demonstrate that the TRACT method can be used to investigate the connectivity of neuronal circuits in the brain. PMID:29231171

BAG3 is a multifunctional protein that can bind to heat shock proteins (Hsp) 70 through its BAG domain and to other partners through its WW domain, proline-rich (PXXP) repeat and IPV (Ile-Pro-Val) motifs. Its intracellular expression can be induced by stressful stimuli, while is constitutive in skeletal muscle, cardiac myocytes and several tumour types. BAG3 can modulate the levels, localisation or activity of its partner proteins, thereby regulating major cell pathways and functions, including apoptosis, autophagy, mechanotransduction, cytoskeleton organisation, motility. A secreted form of BAG3 has been identified in studies on pancreatic ductal adenocarcinoma (PDAC). Secreted BAG3 can bind to a specific receptor, IFITM2, expressed on macrophages, and induce the release of factors that sustain tumour growth and the metastatic process. BAG3 neutralisation therefore appears to constitute a novel potential strategy in the therapy of PDAC and, possibly, other tumours. Copyright © 2017 Elsevier Ltd. All rights reserved.

Internet-based interventions have potential to reduce HIV and STD transmission among men who meet male sexual partners online. From November 2009 to May 2010 we surveyed dating and hook-up website users (n = 3,050), website owners (n = 18), and health department HIV/STD directors (n = 81) to identify structural and behavioral prevention interventions that could be implemented online and which a majority of website users were willing to use, owners were willing to implement, and HIV/STD directors perceived to be effective. A majority of each of the three stakeholder groups agreed on the following: (1) automated HIV/STD testing reminders, (2) local STD test site directories, (3) links to sex-positive safe sex videos, (4) access to sexual health experts, (5) profile options to include safer sex preference, (6) chat rooms for specific sexual interests, (7) filtering partners by their profile information, and (8) anonymous e-card partner notification for STD exposure. Findings help build consensus about how to prioritize resources for implementing online HIV and STD prevention interventions and highlight differences between stakeholders to guide future discussion about how to advance prevention efforts.

Purpose This longitudinal investigation examined potential risk factors for intimate partner violence (IPV) among women during pregnancy and 6 weeks postpartum. Methods A sample of 180 pregnant women was collected in order to investigate 1) whether associations between partner alcohol misuse, partner jealousy, partner suspicion of infidelity, and stress were associated with IPV victimization, 2) the indirect effects of alcohol misuse on these relationships, and 3) factors related to changes in IPV victimization over time. Results At baseline, partner alcohol misuse was associated with each type of IPV victimization and the combination of partner alcohol misuse, partner jealousy, and partner suspicion of infidelity was most strongly associated with severe physical victimization. Partner alcohol misuse mediated the relationship between partner jealousy and psychological and severe physical victimization. At follow-up, partner jealousy and stress were related to women’s psychological victimization and partner alcohol misuse was related to women’s severe physical victimization. Conclusions Findings suggest that partner alcohol misuse is a risk factor for women’s IPV victimization during pregnancy and jealousy and stress may increase risk for some types of IPV. Findings also suggest that intervention should target parents early in pregnancy in order to reduce the risk for future IPV. PMID:23053216

2014-01-01

Many individuals with Substance Use Disorders (SUDs) have been the victims of violence and individuals with SUDs often exhibit coping skills deficits. The extent to which coping skills relate to victimization is unknown. This study evaluated the relationships between physical assault victimization types (i.e., only partner victimization, only non-partner victimization, or both partner and non-partner victimization) and emotion-focused, problem-focused, and avoidant coping among individuals in residential SUD treatment. More frequent use of problem-focused coping was associated with reduced odds of being victimized by partners and non-partners and more frequent use of avoidant coping was associated with increased odds of victimization across both partners and non-partners. These results highlight the potential value of assessing violence across relationship types and bolstering adaptive coping among individuals with SUDs. PMID:24364127

Effects of potential partners' physical attractiveness and socioeconomic status on sexuality and partner selection.

PubMed

Townsend, J M; Levy, G D

1990-04-01

Male (n = 170) and female (n = 212) college students viewed photographs, which had been prerated for physical attractiveness, of three opposite-sex individuals. These photographs were paired with three levels of occupational status and income. Subjects indicated their willingness to engage in relationships of varying levels of sexual intimacy and marital potential with the portrayed individuals. Analyses of variance, correlations, and trend analyses supported the hypotheses. Compared to men, women are more likely to prefer or insist that sexual intercourse occur in relationships that involve affection and marital potential, and women place more emphasis than men do on partners' SES in such relationships. Consequently, men's SES and their willingness and ability to invest affection and resources in relationships may often outweigh the effects of their physical attractiveness in women's actual selection of partners. These results and the literature reviewed are more consistent with parental investment theory than with the view that these sex differences are solely the result of differential access to resources and differential socialization.

Construction of phosphorylation interaction networks by text mining of full-length articles using the eFIP system.

Protein phosphorylation is a reversible post-translational modification where a protein kinase adds a phosphate group to a protein, potentially regulating its function, localization and/or activity. Phosphorylation can affect protein-protein interactions (PPIs), abolishing interaction with previous binding partners or enabling new interactions. Extracting phosphorylation information coupled with PPI information from the scientific literature will facilitate the creation of phosphorylation interaction networks of kinases, substrates and interacting partners, toward knowledge discovery of functional outcomes of protein phosphorylation. Increasingly, PPI databases are interested in capturing the phosphorylation state of interacting partners. We have previously developed the eFIP (Extracting Functional Impact of Phosphorylation) text mining system, which identifies phosphorylated proteins and phosphorylation-dependent PPIs. In this work, we present several enhancements for the eFIP system: (i) text mining for full-length articles from the PubMed Central open-access collection; (ii) the integration of the RLIMS-P 2.0 system for the extraction of phosphorylation events with kinase, substrate and site information; (iii) the extension of the PPI module with new trigger words/phrases describing interactions and (iv) the addition of the iSimp tool for sentence simplification to aid in the matching of syntactic patterns. We enhance the website functionality to: (i) support searches based on protein roles (kinases, substrates, interacting partners) or using keywords; (ii) link protein entities to their corresponding UniProt identifiers if mapped and (iii) support visual exploration of phosphorylation interaction networks using Cytoscape. The evaluation of eFIP on full-length articles achieved 92.4% precision, 76.5% recall and 83.7% F-measure on 100 article sections. To demonstrate eFIP for knowledge extraction and discovery, we constructed phosphorylation-dependent interaction networks involving 14-3-3 proteins identified from cancer-related versus diabetes-related articles. Comparison of the phosphorylation interaction network of kinases, phosphoproteins and interactants obtained from eFIP searches, along with enrichment analysis of the protein set, revealed several shared interactions, highlighting common pathways discussed in the context of both diseases. © The Author(s) 2015.

We aimed to identify individual and sexual partnership characteristics associated with partner notification (PN) among people with STI. We hypothesised that PN would be less likely in more casual sexual partnerships and in partnerships with intimate partner violence (IPV). We conducted an observational study among the first 330 patients with STI enrolled in a trial of a behavioural intervention to reduce STI incidence, at a clinic in a poor, Cape Town community. We included 195 index patients (those reporting STI symptoms), and conducted longitudinal analyses using participant-completed questionnaires on the day of diagnosis and 2 weeks later. Using partnership data for five recent sexual partners, we assessed factors associated with reported PN with logistic regressions, adjusting for repeated measurements on the same participant for each partner. The sample included 99 males with 303 partners and 96 females with 158 partners. Males reported perpetrating IPV in 46.2% of partnerships. Females reported being IPV victims in 53.2% of partnerships. Males notified 58.1%, females 75.4% of partners during the 2 weeks following diagnosis. Type of partner was an independent correlate of PN for males and females, with the odds of PN lower in more casual partnerships. For males, reporting physical IPV perpetration in the partnership was an independent correlate of PN. For females, there was no association between IPV victimisation in a partnership and PN. Efforts to decrease the pool of infectious partners need to have a strong focus on the promotion of PN in casual relationships and one-night stands. IPV was not identified as a barrier to PN. In future, we need to investigate the association between IPV with an objective measure of PN success such as partner testing or treatment, or index patient reinfection.

Explore different methods by which intimate partner violence screening practices are implemented in clinic and emergency settings and better understand barriers and facilitators. Healthcare visits provide an opportunity for providers to identify and provide assistance to victims of intimate partner violence. However, wide variation exists in the implementation of screening and response protocols. In addition, providers experience barriers and facilitators to intimate partner violence screening and response. A comprehensive understanding of these factors is necessary to improve the role that providers play in detection and intervention of intimate partner violence. Qualitative descriptive research design. Sixteen healthcare facilities were recruited from a large metropolitan area in the USA. Data were collected through semi-structured, in-depth interviews with individuals knowledgeable about intimate partner violence screening and response within their facility. Data were analysed using directive content analysis. Major themes and patterns concerning intimate partner violence screening and response were identified within the following areas: procedural characteristics, barriers, facilitators and additional needs. Patient-provider communication and operational/facility characteristics emerged as critical aspects that impact the successful implementation of intimate partner violence screening and response programmes. Differences were found between clinic and emergency settings stemming from variations in health delivery models. Results provide important information on how healthcare facilities implement intimate partner violence screening and response, suggestions for practice improvement and directions for future interventions. Additional guidance is needed to ensure intimate partner violence identification, and response procedures are effective and tailored to needs of patients, providers and the facility. Nurses are in a strategic position to play a pivotal role in identification of and response to intimate partner violence. It is essential that nurses are cognizant of this, and understand the actions they can take to assist patients who have been victims of intimate partner violence. Recommendations on how to do this are provided. © 2016 John Wiley & Sons Ltd.

Spouse/partners of military personnel demonstrate elevated levels of distress during military deployments, yet there is insufficient information about courses of adjustment over time. The current study identified trajectories of depression and alcohol use problems and predictors of those trajectories across the deployment cycle. National Guard soldiers (N = 1973) and spouses/intimate partners (N = 1020) completed assessments of risk/protective factors and baseline measures of mental health functioning 2 to 5 months prior to soldiers' 1-year deployments (Time 1) to Kuwait/Iraq in support of Operation New Dawn or Afghanistan in support of Operation Enduring Freedom. Partners' mental health was reassessed at 4 months (Time 2) and 8 months (Time 3) after soldiers deployed, and both spouses/partners and soldiers were reassessed 2-3 months postdeployment (Time 4). Latent class growth modeling of partner depression symptoms over time revealed 4 groups: Resilience (79.9%), Deployment Distress (8.9%), Anticipatory Distress (8.4%), and Post-Deployment Distress (2.7%). Three alcohol misuse trajectories were identified: Resilience (91.3%), Deployment Onset (5.4%), and Deployment Desistance (3.3%). Predeployment predictors of partners' depression symptom trajectories varied by group and included soldier reports of stressors and social support and partner levels of neuroticism, introversion, disconstraint, and reported stressors. Predeployment predictors of alcohol misuse trajectories varied by group, and included soldier levels of alcohol misuse as well as partner neuroticism, disconstraint, and family readiness. Delineating and predicting trajectories of partner adjustment can allow for better targeted interventions toward those most at risk for heightened distress or alcohol problems over the deployment cycle.

Weight stigma in existing romantic relationships.

PubMed

Boyes, Alice D; Latner, Janet D

2009-01-01

Associations between body mass index (BMI; kg/m2) and relationship quality and other partner/relationship perceptions were investigated in 57 dating or married couples. Heavier women had lower quality relationships, which they predicted were more likely to end. They partnered with less desirable men and thought their partners would rate them as less warm/trustworthy. Heavier women were judged by their male partners as lower in attractiveness/vitality and as poorer matches to their partners' attractiveness ideals. In contrast, men's BMI was generally not associated with relationship functioning. These findings point to the potential mechanisms that may contribute to heavier women's relationship difficulties.

Intimate-partner homicide among pregnant and postpartum women.

PubMed

Cheng, Diana; Horon, Isabelle L

2010-06-01

To identify pregnancy-associated homicide cases and to estimate the proportion that were perpetrated by a current or former intimate partner. This was an analysis of pregnancy-associated homicides occurring from 1993 to 2008 among Maryland residents using linked birth and death certificates, medical examiner charts, police records, and news publications. Homicides (n=110) were the leading cause of death during pregnancy and the first postpartum year. Women who were African American, younger than 25 years, and unmarried were at the highest risk for homicide. Firearms were the most common (61.8%) method of death. A current or former intimate partner was the perpetrator in 54.5% (n=60) of homicide deaths and a nonpartner in 31.8% (n=35). If the cases (n=15) in which the victim-offender relationship could not be identified are excluded, 63.2% of homicides were committed by an intimate partner. Compared with homicides in which the perpetrator was not an intimate partner, a significantly higher percentage (P<.05) of intimate-partner homicides occurred at home (66.7% compared with 28.6%), among women who had completed more than 12 years of education (23.3% compared with 5.7%), and who were married (28.3% compared with 8.6%). Intimate-partner homicides were most prevalent (25.0%) during the first 3 months of pregnancy and least prevalent during the first 3 months postpartum (5.0%). The majority of pregnancy-associated homicides were committed by current or former intimate partners, most commonly during the first 3 months of pregnancy. Efforts to protect women from partners optimally should begin before conception or very early in pregnancy. III.

Sex differences in mate preferences revisited: do people know what they initially desire in a romantic partner?

PubMed

Eastwick, Paul W; Finkel, Eli J

2008-02-01

In paradigms in which participants state their ideal romantic-partner preferences or examine vignettes and photographs, men value physical attractiveness more than women do, and women value earning prospects more than men do. Yet it remains unclear if these preferences remain sex differentiated in predicting desire for real-life potential partners (i.e., individuals whom one has actually met). In the present study, the authors explored this possibility using speed dating and longitudinal follow-up procedures. Replicating previous research, participants exhibited traditional sex differences when stating the importance of physical attractiveness and earning prospects in an ideal partner and ideal speed date. However, data revealed no sex differences in the associations between participants' romantic interest in real-life potential partners (met during and outside of speed dating) and the attractiveness and earning prospects of those partners. Furthermore, participants' ideal preferences, assessed before the speed-dating event, failed to predict what inspired their actual desire at the event. Results are discussed within the context of R. E. Nisbett and T. D. Wilson's (1977) seminal article: Even regarding such a consequential aspect of mental life as romantic-partner preferences, people may lack introspective awareness of what influences their judgments and behavior.

Background Identifying cohorts of US women with HIV infection rates sufficient for inclusion in vaccine efficacy trials has been challenging. Using geography and sexual network characteristics to inform recruitment strategies, HVTN 906 determined the feasibility of recruiting a cohort of women at high risk for HIV acquisition. Methods HIV uninfected women who reported unprotected sex in the prior six months, resided or engaged in risk behavior in local geographical high-risk pockets and/or had a male partner who had been incarcerated, injected drugs or had concurrent partners were eligible. Behavioral risk assessment, HIV counseling and testing and pregnancy testing were done at baseline, 6, 12 and 18 months. Results Among 799 women, 71% were from local high-risk pockets and had high-risk male partners. Median age was 37 years; 79% were Black; 15% Latina. Over half (55%) reported a new partner in the prior six months, 57% reported a male partner who had concurrent female sexual partners and 37% reported a male partner who had been incarcerated. Retention at 18 months was 79.5%. Annual pregnancy incidence was 12%. Annual HIV incidence was 0.31% (95% CI: 0.06, 0.91). Risk behaviors decreased between screening and six months with smaller changes thereafter. Discussion This cohort of women recruited using new strategies based on geography and sexual network characteristics did not have an HIV incidence high enough for HIV vaccine efficacy trials, despite high baseline levels of risk and a high pregnancy rate. New strategies to identify cohorts of US women for efficacy trials are needed. PMID:23446497

Urban Adolescent Girls’ Perspectives on Multiple Partners in the Context of the Sexual Double Standard and Intimate Partner Violence

This article describes the influence of abusive and non-abusive relationship dynamics on the number of sex partners among urban adolescent girls. Focus groups were conducted with 64 sexually active adolescent girls ages 14 to 17 years. General coding and content analyses identified patterns, themes, and salient beliefs. More than one third (37.5%) reported having experienced physical, intimate partner violence; 32.8% had 2 or more recent sex partners, and 37.5% had ever had a sexually transmitted infection (STI) or HIV. Although some girls in abusive relationships feared retribution if they had more than one partner, others sought additional partners for solace or as an act of resistance. Adolescent HIV/STI prevention programs need to address the influence of gender norms such as the sexual double standard as well as partner pressure and partner abuse on adolescent decision-making about safer sex, and also promote healthy relationships as integral to advancing HIV/STI risk reduction.

2016-04-01

Significant numbers of sexual minority women are choosing to parent. Despite this, there is limited research on postpartum depression (PPD) with sexual minority mothers and less research considering differences within sexual minority women in the experience of PPD. This research examines two questions to address this gap in research: (1) Do experiences of PPD symptoms vary between different subgroups of sexual minority women, and (2) Which recruitment strategies effectively address the challenge of recruiting sexual minority women who are pregnant? Two Canadian studies recruited participants via consecutive or convenience sampling from midwifery clinics and hospital sites. Participants completed prenatal and postnatal measures of PPD symptoms, social support, and perceived discrimination. Considering our first question, we found an interaction effect between past sexual behavior and current partner gender. Women currently partnered with men reported higher scores on the Edinburgh Postpartum Depression Scale when their sexual history included partners of more than one gender, whereas this effect was not found among women who were currently partnered with women or not partnered. Regarding our second question, most sexual minority participants recruited through convenience sampling were partnered with women and identified as lesbian or queer, while most participants recruited through consecutive sampling were partnered with men and identified as bisexual. Women whose sexual histories include more than one gender and are currently partnered with men may be at a higher risk for PPD symptoms. Recruitment method may influence the type of sample recruited for perinatal mental health research among sexual minority women.

We conducted a cross-sectional study among 148 women who were regular sexual partners of male injecting drug users in Tien Du, Bac Ninh province, Vietnam to identify the rate of HIV infection and factors associated with HIV transmission among them. HIV infection rate among sexual partners was high, 11.5%. Sexual violence was prevalent, 63.5% among sexual partners; 94.1% (16/17) among those with HIV. We discovered an association between sexual violence and HIV infection. Sexual partners suffering from sexual violence caused by their regular sexual partners faced 9.24 times higher HIV risk than those who did not have sexual violence.

2010-01-01

The goal of the present study was to identify the most important jealousy-evoking partner behaviours and to examine the extent to which these behaviours evoke jealousy. Based on the literature, a questionnaire was constructed containing 42 jealousy-evoking partner behaviours, including a partner's extra-dyadic involvement with someone else by means of modern communication devices, such as the Internet. A second study examined the extent to which undergraduates and a community sample experienced jealousy in response to these partner behaviours. Results showed that explicit unfaithful behaviours evoked most feelings of jealousy, followed by a partner's emotional or romantic involvement with someone else by means of modern communication devices. In general, older individuals responded with less jealousy in response to a partner's unfaithful and suspicious behaviours. Clinical implications are discussed. (c) 2009 John Wiley & Sons, Ltd.

Close partner as sculptor of the ideal self: behavioral affirmation and the Michelangelo phenomenon.

This work incorporates concepts from the behavioral confirmation tradition, self tradition, and interdependence tradition to identify an interpersonal process termed the Michelangelo phenomenon. The Michelangelo phenomenon describes the means by which the self is shaped by a close partner's perceptions and behavior. Specifically, self movement toward the ideal self is described as a product of partner affirmation, or the degree to which a partner's perceptions of the self and behavior toward the self are congruent with the self's ideal. The results of 4 studies revealed strong associations between perceived partner affirmation and self movement toward the ideal self, using a variety of participant populations and measurement methods. In addition, perceived partner affirmation--particularly perceived partner behavioral affirmation--was strongly associated with quality of couple functioning and stability in ongoing relationships.

A body of research has established that lower socioeconomic populations, including blue-collar workers, are at higher risk for problem drinking and intimate partner violence. This study of married/cohabiting construction workers and their spouses/partners describes how work stressors, hazardous drinking, and couple characteristics interact to influence normative beliefs around partner violence and, thereafter, its occurrence. Our survey respondents from a sample of 502 dual-earner couples were asked about drinking patterns, past-year partner violence, normative beliefs about partner violence, work-related stressors, impulsivity, and childhood exposure to violence and other adverse events. We conducted semi-structured qualitative interviews with 81 workers on context of work stress, partner violence, and drinking. Analyses of data revealed that men's and women's normative beliefs about partner violence were positively related to maleto- female partner violence; female partner violence normative beliefs were associated with female-to-male partner violence. Both partners' levels of impulsivity were directly associated with male-to-female and female-to-male partner violence, and male partner's frequency of intoxication mediated the association between level of impulsivity and male-to-female partner violence. Female partner's adverse childhood experience was directly associated with male-to-female partner violence. Both survey and qualitative interviews identified individual and workrelated factors that influence the occurrence of violence between men and women. These findings provide guidelines for prevention of partner violence that can be implemented in the workplace with attention to hazardous drinking, job stress, treatment, education, and work culture.

Sexual Orientation Self-Presentation Among Bisexual-Identified Women and Men: Patterns and Predictors.

PubMed

Mohr, Jonathan J; Jackson, Skyler D; Sheets, Raymond L

2017-07-01

Writing on the experiences of bisexual-identified people has highlighted the potential complexity of the ongoing process of deciding when and how to present one's sexual orientation identity to others (Rust, 2002). The two studies presented here were designed to contribute basic knowledge regarding self-presentation of sexual orientation among bisexual people. In Study 1, bisexual participants (N = 147) were less likely than their lesbian and gay (LG) peers (N = 191) to present their actual orientation to others, and more likely to present themselves as having a sexual orientation different from their actual orientation. These sexual orientation differences were explained by gender of romantic partner and uncertainty about one's sexual orientation. Sexual orientation differences also emerged in links between self-presentation and outness level. For example, bisexual participants who presented themselves as LG had relatively high everyday outness levels; in contrast, LG participants who presented themselves as bisexual had relatively low everyday outness levels. In Study 2, 240 bisexual women and men indicated their levels of outness as a sexual minority person (potentially including identification as gay, lesbian, queer) and specifically as bisexual. Outness was higher with respect to status as a sexual minority compared to status as bisexual; the magnitude of this difference was predicted by gender of romantic partner and uncertainty about one's sexual orientation. Moreover, even controlling for outness as a sexual minority person, well-being was predicted by outness as bisexual to family members.

The role of aquaporin-5 in cancer cell migration: A potential active participant.

Emerging data identifies the water channel aquaporin-5 as a major player in multiple cancers. Over-expression of aquaporin-5 has been associated with increased metastasis and poor prognosis, suggesting that aquaporin-5 may enhance cancer cell migration. This review aims to highlight the current knowledge and hypothesis regarding downstream signaling partners of aquaporin-5 in relation to cancer cell migration. The molecular mechanisms that link aquaporin-5 to cell migration are not completely understood. Aquaporin-5 may promote cell movement by increasing water uptake into the front of the cell allowing local swelling. Aquaporin-5 may also activate extracellular-regulated kinases, increasing proliferation and potentially stimulating the migration machinery. Thus, further studies are warranted to identify the underlying mechanisms and signaling pathways. This will reveal whether aquaporin-5 and downstream effectors could be targets for developing new cancer therapeutics. Copyright © 2016 Elsevier Ltd. All rights reserved.

Sexual Preferences and Presentation on Geosocial Networking Apps by Indian Men Who Have Sex With Men in Maharashtra.

Rhoton, Jayson; Wilkerson, J Michael; Mengle, Shruta; Patankar, Pallav; Rosser, B R Simon; Ekstrand, Maria L

2016-10-31

The affordability of smartphones and improved mobile networks globally has increased the popularity of geosocial networking (GSN) apps (eg, Grindr, Scruff, Planetromeo) as a method for men who have sex with men (MSM) to seek causal sex partners and engage with the queer community. As mobile penetration continues to grow in India, it is important to understand how self-presentation on GSN app is relevant because it offers insight into a population that has not been largely studied. There is very little information about how Indian MSM discuss their sexual preferences and condom preferences and disclose their human immunodeficiency virus (HIV) status with potential sex partners on Web-based platforms. The objective of this study was to describe how self-presentation by Indian MSM on GSN apps contributes to sexual preferences, HIV or sexually transmitted infection (STI) disclosure, and if the presentation differs due to proximity to the Greater Mumbai or Thane region. Between September 2013 and May 2014, participants were recruited through banner advertisements on gay websites, social media advertisements and posts, and distribution of print materials at outreach events hosted by lesbian, gay, bisexual, transgender (LGBT) and HIV service organizations in Maharashtra, India. Eligible participants self-identified as being MSM or hijra (transgender) women, living in Maharashtra, aged above 18 years, having regular Internet access, and having at least one male sex partner in the previous 90 days. Indian MSM living inside and outside the Greater Mumbai or Thane region reported an average of 6.7 (SD 11.8) male sex partners in the last 3 months; on average HIV status of the sex partners was disclosed to 2.9 (SD 8.9). The most commonly used websites and GSN apps by MSM living inside Greater Mumbai or Thane region were Planetromeo, Grindr, and Gaydar. Results demonstrated that MSM used smartphones to access GSN apps and stated a preference for both condomless and protected anal sex but did not disclose their HIV status. This low level of HIV disclosure potentially increases risk of HIV or STI transmission; therefore, trends in use should be monitored. Our data helps to fill the gap in understanding how Indian MSM use technology to find casual sex partners, disclose their sexual preference, and their HIV status on Web-based platforms. As mobile penetration in India continues to grow and smartphone use increases, the use of GSN sex-seeking apps by MSM should also increase, potentially increasing the risk of HIV or STI transmission within the app's closed sexual networks. ©Jayson Rhoton, J Michael Wilkerson, Shruta Mengle, Pallav Patankar, BR Simon Rosser, Maria L Ekstrand.

Soldiers' Preferences Regarding Sperm Preservation, Posthumous Reproduction, and Attributes of a Potential "Posthumous Mother".

PubMed

Bokek-Cohen, Ya'arit; Ravitsky, Vardit

2017-01-01

We present study results regarding soldiers' willingness to conduct posthumous reproduction. Two hundred twelve Israeli soldiers filled in a questionnaire designed to examine their willingness to cryopreserve sperm and evaluate in which familial circumstances they would consent to posthumous reproduction. They ranked the desirability of 46 attributes of a potential mother and a life partner. Findings indicate a relatively high predisposition in favor of posthumous-assisted reproduction; the wishes of soldiers' parents had much more influence on soldiers' willingness to pursue this technology than those of a partner. Soldiers preferred "feminine" jobs for a potential mother that would allow her to dedicate herself to child-rearing. The desired traits of such a mother were rated similarly to partner preferences; however, significant differences were found in attributes that are most related to the potential mother's devotion to maternity. Interpretations of these findings are contextualized in relation to ethical and bereavement considerations.

The Potential of Pre-Exposure Prophylaxis for Women in Violent Relationships.

PubMed

Braksmajer, Amy; Senn, Theresa E; McMahon, James

2016-06-01

HIV and intimate partner violence (IPV) are significant intersecting threats to women's health. Women in violent relationships have few feasible HIV risk reduction options as traditional prevention methods are largely dependent on a partner's cooperation. The purpose of this review is to explore potential benefits and drawbacks of pre-exposure prophylaxis (PrEP) use among women in the United States experiencing IPV. Advantages of PrEP use in this population include the potential for covert or autonomous use, coital independence, dual protection against sexual and injection risk, and facilitated connections to social services. A number of barriers, however, may interfere with the effective use of PrEP, including partner resistance, cost, frequent medical visits, gendered norms regarding sexuality, and stigma. To realize its potential for women in violent relationships, it will be necessary to incorporate PrEP into behavioral and structural interventions that encourage uptake, facilitate adherence, ensure women's safety, and challenge existing gender norms.

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.

Although exome sequencing data are generated primarily to detect single-nucleotide variants and indels, they can also be used to identify a subset of genomic rearrangements whose breakpoints are located in or near exons. Using >4,600 tumor and normal pairs across 15 cancer types, we identified over 9,000 high confidence somatic rearrangements, including a large number of gene fusions. We find that the 5′ fusion partners of functional fusions are often housekeeping genes, whereas the 3′ fusion partners are enriched in tyrosine kinases. We establish the oncogenic potential of ROR1-DNAJC6 and CEP85L-ROS1 fusions by showing that they can promote cell proliferation in vitro and tumor formation in vivo. Furthermore, we found that ∼4% of the samples have massively rearranged chromosomes, many of which are associated with upregulation of oncogenes such as ERBB2 and TERT. Although the sensitivity of detecting structural alterations from exomes is considerably lower than that from whole genomes, this approach will be fruitful for the multitude of exomes that have been and will be generated, both in cancer and in other diseases.

Piotrowski, Caroline C

2011-02-01

This research explored and compared patterns of adjustment in siblings exposed to intimate partner violence. The quality of family relationships were investigated as potential mechanisms that accounted for heterogeneity in these patterns. Participants included 47 sibling pairs and their mothers recruited from the community. Mothers and children reported on child adjustment measures and the quality of family relationships. Five cluster patterns were identified for both younger and older siblings, replicating three identified in previous research: primarily internalizing symptoms, a combination of internalizing and externalizing symptoms, and an asymptomatic cluster. There was little overlap in cluster membership within families; most siblings differed in terms of their pattern of adjustment. The quality of family relationships varied significantly across clusters. Overall, asymptomatic siblings reported the most positive family relationships. Maternal warmth differed across clusters for both older and younger siblings, while maternal hostility varied across clusters for older but not younger siblings. The quality of sibling relationships also differed across clusters for older but not younger siblings. These findings underscore the importance of examining differential sibling experiences within violent families, and demonstrate the significance of family relationships as a mediating mechanism influencing heterogeneous child adjustment.

Syphilis Networks in Louisiana: An Analysis of Network Configuration and Disease Transmission

NASA Astrophysics Data System (ADS)

Desmarais, Catherine Theresa

Background: In 2009, Louisiana had the highest rate of primary and secondary syphilis in the country. Recent partner notification approaches have been insufficient in addressing Louisiana's deeply entrenched areas of syphilis infection. Prior researchers have suggested that surveillance systems may benefit from utilizing social and spatial network analysis in syphilis control efforts. Objective: To expand the understanding of the spread of syphilis in Louisiana, and to add new tools to the state's case finding resources through the description of the characteristics of cases of early syphilis and their partners in Louisiana, the socio-sexual networks of these cases, and the geospatial clustering of cases and partners. Methods: Utilizing state surveillance data, all cases of primary, secondary, and early latent syphilis that were diagnosed in 2009 and data on their sexual or needle sharing partners were analyzed using a combination of descriptive, network, and geospatial measures. Results: In 2009, Louisiana experienced a high rate of heterosexual syphilis transmission. Within syphilis transmission networks, 50.8% of all cases were female and 84.2% of all cases were black. The average and median ages of males with reactive syphilis tests were higher than that of females in Louisiana, and in 88.9% of regions, older individuals were more likely to have a syphilis test than no test. A greater proportion of males (11.4%) refused to discuss partners than females (7.4%) and a greater proportion of males (5.5%) refused testing and prophylactic treatment than females (2.8%). No distinct patterns were seen in disease prevalence between regions based upon demographic data. Classic summary network measures such as density, degree, centrality, and betweenness provided little information on similarities and differences between the different regions in Louisiana. All measures indicated low density and extreme fragmentation of networks in Louisiana. The majority of network structures were dendritic in nature. A total of 121 cases did not report any partners and an additional 15.9% reported only being involved in dyads. Several large connected components were also observed in syphilis transmission networks in Louisiana. The average age of persons in these large components was greater than in the regional network. A total of 27.3% of male partnerships were with other males in Louisiana, and 4.0% of female pairings were with other females. Blacks practiced assortative mixing, with 93.1% of contacts with a reported race/ethnicity also being black, while 58.9% of contacts reported by whites were also white. Visualization of networks at the regional level illustrated different patterns, with some regions having large disconnected networks while others had more highly connected components. Visualization also uncovered a high concentration of males that had sex with males and females within Region 2 that were note detected during descriptive analyses. Graphs also highlighted highly connected persons within networks that did not have reactive syphilis tests. Upon geocoding the addresses of network members, it was found that most persons lived adjacent to major highways and in major urban areas. Cluster analyses detected a large number of geographic clusters of study subjects throughout the state. Several different patterns were identified; regions with many clusters in a small geographic area, regions with many clusters over a wide geographic area, regions with few clusters, and regions with no small clusters. Most regions had geographically small clusters of a size that could benefit from targeted interventions. Conclusion: This study provides a more in-depth understanding of syphilis spread in the state of Louisiana and demonstrates the feasibility of using network and geospatial methods in future state surveillance and prevention activities. By tying these two approaches together with the addition of basic demographic information, regional patterns can be identified to improve syphilis prevention practices. In areas with disconnected networks but close geographic clustering, community and street level testing has the potential to reduce morbidity more than partner elicitation, which has resulted in highly fragmented networks. The combination of these analyses also identified subpopulations in need of special messaging or intervention, such as sex workers and males that have sex with both males and females, and identified persons within the networks that would not typically be targeted for cluster interviews but, due to network position, may be helpful in finding additional morbidity in the region. These analyses are feasible to be carried out in an ongoing manner at the state level using current data collection processes and have the potential to inform syphilis elimination activities in each region and within the state as a whole. The addition of risk behaviors, HIV status, venues where partners are met, and the use of the internet and apps in finding partners to future analyses will further improve these disease elimination approaches in Louisiana.

Latino youth in the United States are at greater risk for contracting sexually transmitted infections (STIs) in comparison with non-Hispanic white youth. Sexually active heterosexual Latino youth aged 16 to 22 years (N = 647) were recruited for interviews through a large health maintenance organization or community clinics. Adjusting for gender, age, ethnic heritage, and recruitment method, woman's consistent use of hormonal contraceptives, ambivalence about avoiding pregnancy, longer length of sexual relationship, and greater overall trust in main partner were independently associated with inconsistent condom use and engagement in a greater number of sexual intercourse acts that were unprotected by condom use. Perception that one's main partner had potentially been unfaithful, but not one's own sexual concurrency, was associated with consistent condom use and fewer acts of unprotected sexual intercourse. Sexually concurrent youth who engaged in inconsistent condom use with other partners were more likely to engage in inconsistent condom use and a greater number of unprotected sexual intercourse acts with main partners. Increasing attachment between youth may be a risk factor for the transmission of STIs via normative declines in condom use. Perception that one's partner has potentially been unfaithful may result in greater condom use. However, many Latino adolescents and young adults who engage in sexual concurrency may not take adequate steps to protect their partners from contracting STIs. Some youth may be more focused on the emotional and social repercussions of potentially revealing infidelity by advocating condom use than the physical repercussions of unsafe sex.

Provoked vestibulodynia (PVD) is a recurrent idiopathic vulvo-vaginal pain associated with negative sexual and psychological consequences. Facilitative partner responses to pain are currently receiving empirical attention because they are positively associated with women's sexual outcomes. However, the mechanisms through which facilitative responses to pain are associated with these outcomes have not been examined. One potential mechanism is sexual assertiveness, which has been found to be associated with better sexual function and satisfaction in women with PVD. The present study examined whether women's sexual assertiveness mediated the association between women's perception of facilitative partner responses and women's sexual function and satisfaction. Women (N = 140) with PVD symptomatology completed self-reported questionnaires evaluating their perception of their partners' facilitative responses, and their own sexual assertiveness, sexual function, and sexual satisfaction. Dependent measures were sexual function measured by the Female Sexual Function Index and sexual satisfaction assessed by the Global Measure of Sexual Satisfaction Scale. Results indicated that women's higher sexual assertiveness mediated the association between their greater perceived facilitative partner responses and their improved sexual function and satisfaction. Findings suggest a potential mechanism through which partner responses may be associated with women's sexual outcomes.

The prevalence of HIV-positive pregnant women in relationships with HIV-negative men in the United States is unclear. The purpose of this study was to calculate the prevalence of HIV-positive pregnant women with a serodiscordant (HIV-negative) partner within a single clinic population, assess disclosure of their HIV status, and examine factors associated with disclosure. All HIV-positive pregnant women who received prenatal care at the Harris County Hospital District Women's Program at Northwest Health Center in Houston TX between 1/1/2006 and 4/1/2011 were identified. Data were obtained from electronic medical records. Prevalence of serodiscordance and disclosure was calculated, and predictors of disclosure were evaluated. We identified 212 HIV-positive pregnant women. About 40% had a serodiscordant partner, and 34% had a partner with an unknown HIV status. Disclosure occurred in over 90% of women with a serodiscordant partner and in 68% of women with partners whose HIV status was unknown. Among pregnant women who knew their HIV status prior to the current pregnancy and had a serodiscordant partner, 92% reported disclosing their status prior to conception. Our data indicated that serodiscordant relationships are common in our clinic population. Suboptimal disclosure rates were observed, especially among women who have a partner with an unknown HIV status. Further research is needed to evaluate the prevalence of serodiscordance and disclosure in other United States populations.

Dyadic Qualitative Analysis of Condom Use Scripts Among Emerging Adult Gay Male Couples.

2018-04-03

Sexual risk reduction among gay male couples has received increasing attention in light of evidence that primary partners account for many-and possibly most-new HIV infections. This study examined the content of condom use scripts in interviews conducted with both members of 17 HIV-negative gay male couples. In each couple, at least one partner was an emerging adult (aged 18 to 29). Three scripts were identified: romantic love, unanticipated condomless anal intercourse (CAI), and negotiated safety. Scripts varied in their emphasis on emotional factors versus HIV risk reduction, the salience of sexual agreements, and the presence of an explicit communication goal. Results indicated that condom use may vary for couples as a result of script content and from the fluid adoption of scripts across contexts. Results highlighted potential tensions between emotional closeness and HIV prevention. Condom use cessation and sexual agreements-a potential mechanism for HIV risk reduction-may also serve as expressions of intimacy. This implies interventions that facilitate direct communication about sexual and relational goals-as well as those that expand couples' repertoires for expressing emotional closeness-may enhance sexual health for gay couples, particularly during the period of emerging adulthood.

Background: When conducting research with American Indian tribes, informed consent beyond conventional institutional review board (IRB) review is needed because of the potential for adverse consequences at a community or governmental level that are unrecognized by academic researchers. Objectives: In this article, we review sovereignty, research ethics, and data-sharing considerations when doing community-based participatory health–related or natural-resource–related research with American Indian nations and present a model material and data-sharing agreement that meets tribal and university requirements. Discussion: Only tribal nations themselves can identify potential adverse outcomes, and they can do this only if they understand the assumptions and methods of the proposed research. Tribes must be truly equal partners in study design, data collection, interpretation, and publication. Advances in protection of intellectual property rights (IPR) are also applicable to IRB reviews, as are principles of sovereignty and indigenous rights, all of which affect data ownership and control. Conclusions: Academic researchers engaged in tribal projects should become familiar with all three areas: sovereignty, ethics and informed consent, and IPR. We recommend developing an agreement with tribal partners that reflects both health-related IRB and natural-resource–related IPR considerations. PMID:21890450

We are just beginning to unravel the myriad of interactions in which non-coding RNAs participate. The intricate RNA interactome is the foundation of many biological processes, including bacterial virulence and human disease, and represents unexploited resources for the development of potential therapeutic interventions. However, identifying specific associations of a given RNA from the multitude of possible binding partners within the cell requires robust high-throughput systems for their rapid screening. Here, we present the first demonstration of functional-RNA arrays as a novel platform technology designed for the study of such interactions using immobilized, active RNAs. We have generated high-density RNA arrays by an innovative method involving surface-capture of in vitro transcribed RNAs. This approach has significant advantages over existing technologies, particularly in its versatility in regards to binding partner character. Indeed, proof-of-principle application of RNA arrays to both RNA-small molecule and RNA-RNA pairings is demonstrated, highlighting their potential as a platform technology for mapping RNA-based networks and for pharmaceutical screening. Furthermore, the simplicity of the method supports greater user-accessibility over currently available technologies. We anticipate that functional-RNA arrays will find broad utility in the expanding field of RNA characterization.

To determine factors associated with age-disparate sexual partners among Vancouver gay, bisexual and other men who have sex with men (GBM). Sexually active GBM aged ≥16 years were recruited from February 2012 to February 2014. Participants self-completed a questionnaire on demographics, attitudes and sexual behaviour and substance use at last sexual event with five most recent partners. Two generalised linear mixed models identified factors associated with: (1) 'same-age' (referent), 'younger' or 'much-younger' and (2) 'same-age' (referent), 'older' or 'much-older' partners. Statistical interactions between age and HIV status were tested. Participants (n=719) were predominantly gay (85.1%), White (75.0%), HIV-negative/unknown status (72.9%) with median age of 33 years (Q1,Q3: 26,47). A minority of sexual events were reported with much-older/much-younger partners (13.7%). In the multivariable models, GBM reporting older partners were more likely to be Asian or Latino, have greater Escape Motivation scores, report their partner used erectile dysfunction drugs (EDDs) and have received something for sex; compared with condom-protected insertive anal sex, participants with older partners were more likely to report condomless insertive anal sex with a serodiscordant or unknown status partner or no insertive anal sex. GBM reporting older partners were less likely to be bisexual-identified, have given something for sex and report event-level alcohol and EDD use. GBM reporting younger partners were more likely to have annual incomes >$30 000 and have met their partner online. As per significant statistical interactions, age-disparate relations were more common for younger HIV-positive and older HIV-negative GBM. Differences among age-disparate partners highlight important targets for health promotion and future research. Published by the BMJ Publishing Group Limited.

Domestic violence is the most common cause of nonfatal injury to women in North America. In a review of 144 such injuries, the second most common manifestation of intimate partner violence was musculoskeletal injuries (28%). The American Academy of Orthopaedic Surgeons is explicit that orthopaedic surgeons should play a role in the screening and appropriate identification of victims. We aimed to identify the perceptions, attitudes, and knowledge of Canadian orthopaedic surgeons with regard to intimate partner violence. We surveyed members of the Canadian Orthopaedic Association to identify attitudes toward intimate partner violence. With use of a systematic random sample, 362 surgeons were mailed questionnaires. The questionnaire consisted of three sections: (1) the general attitude of the orthopaedic surgeon toward intimate partner violence, (2) the attitude of the orthopaedic surgeon toward victims and batterers, and (3) the clinical relevance of intimate partner violence in orthopaedic surgery. Up to three follow-up mailings were performed to enhance response rates. A total of 186 orthopaedic surgeons responded (a response rate of 51%), and 167 (91%) of them were men. Most orthopaedic surgeons (95%) estimated that <10% of their patients were victims of intimate partner violence, and most respondents (80%) believed that it was exceedingly rare (a prevalence of <1%). The concept of mandatory screening for intimate partner violence was met with uncertainty by 116 surgeons (64%). Misconceptions were perpetuated by surgeons who believed that inquiring about intimate partner violence was an invasion of the victim's privacy, that investigating intimate partner violence was not part of their duty, that victims choose to be a victim, and that victims play a proactive role in causing their abuse. By the completion of the survey, the majority of surgeons (91%) believed that knowledge about intimate partner violence was relevant to their surgical practice. Discomfort with the issue and lack of education have led to misconceptions among Canadian orthopaedic surgeons about intimate partner violence. The relevance of intimate partner violence to surgical practice is well understood, but studies regarding its prevalence are needed as a first step to change the current paradigm in orthopaedic surgery.

To estimate differential associations between the exposure to violence in the family of origin and victimization and perpetration of intimate partner violence in pregnancy. A nested case-control study was carried out within a cohort study with 1,120 pregnant women aged 18-49 years old, who were registered in the Family Health Strategy of the city of Recife, State of Pernambuco, Brazil, between 2005 and 2006. The cases were the 233 women who reported intimate partner violence in pregnancy and the controls were the 499 women who did not report it. Partner violence in pregnancy and previous experiences of violence committed by parents or other family members were assessed with a standardized questionnaire. Multivariate logistic regression analyses were modeled to identify differential associations between the exposure to violence in the family of origin and victimization and perpetration of intimate partner violence in pregnancy. Having seen the mother suffer intimate partner violence was associated with physical violence in childhood (OR = 2.62; 95%CI 1.89-3.63) and in adolescence (OR = 1.47; 95%CI 1.01-2.13), sexual violence in childhood (OR = 3.28; 95%CI 1.68-6.38) and intimate partner violence during pregnancy (OR = 1.47; 95% CI 1.01 - 2.12). The intimate partner violence during pregnancy was frequent in women who reported more episodes of physical violence in childhood (OR = 2.08; 95%CI 1.43-3.02) and adolescence (OR = 1.63; 95%CI 1.07-2.47), who suffered sexual violence in childhood (OR = 3.92; 95%CI 1.86-8.27), and who perpetrated violence against the partner (OR = 8.67; 95%CI 4.57-16.45). Experiences of violence committed by parents or other family members emerge as strong risk factors for intimate partner violence in pregnancy. Identifying and understanding protective and risk factors for the emergence of intimate partner violence in pregnancy and its maintenance may help policymakers and health service managers to develop intervention strategies.

Older women, intimate partner violence and mental health: a consideration of the particular issues for health and healthcare practice.

To explore qualitative evidence in older women with a history of intimate partner violence and their accounts and experiences of mental health. Intimate partner violence significantly impacts the health and well-being of women who experience it. However, women who experience intimate partner violence do not form a homogenous group and the effect on older women has not been adequately distinguished. While there is a growing body of evidence to address this deficit, studies to date have tended to concentrate on older women's experiences of intimate partner violence in totality and as such mental health issues have been subsumed as a part of the whole. Meta-ethnographic synthesis of qualitative evidence. A systematic search of PUBMED, Cumulative Index to Nursing and Allied Health Literature, COCHRANE, Medline and PsycInfo, Sci was completed. The search included articles published up until the end of December 2015. The review identified that intimate partner violence exerts a significant impact on the mental health of older women. Intimate partner violence for women in later life is inherently complex, especially where the boundaries of violence and vulnerability have been blurred historically both within the intimate partner violence discourse and through provision and practice. This study adds to the developing knowledge and understanding of intimate partner violence for older women as a part of the growing body of evidence of the impact of intimate partner violence on the health and well-being of those who experience abuse more generally. When age and gender intersect with intimate partner violence, there are specific implications and health professionals and service providers need to be aware of these. urses and healthcare professionals are professionally accountable for the effective management and support of women who have experienced abuse. It is therefore crucial that they are able to understand and identify the possible complexity of presentations of abuse and this includes older women. © 2016 John Wiley & Sons Ltd.

Mental health and well-being concerns of fly-in fly-out workers and their partners in Australia: a qualitative study

Vandelanotte, Corneel

2018-01-01

Objectives Fly-in fly-out (FIFO) work involves commuting long distances to the worksite and living in provided accommodation for 1–4 weeks while on shift. While the potentially detrimental impact of FIFO work on the health and well-being of workers has been documented, little attention has been paid to how workers, or their partners, cope with this impact. This study sought to investigate how workers and their partners negotiate the impact of FIFO on their mental health and well-being. Design The study design was qualitative. FIFO workers and partners responded to open-ended questions on concerns about the FIFO lifestyle and the support they use. Setting Australian FIFO workers and partners responded to the questions via email. Participants Participants were 34 FIFO workers (25 men, M age=41 years) and 26 partners of FIFO workers (26 women, M age=40 years). Results Participant-validated thematic analysis generated three main themes: managing multiple roles, impact on mental health and well-being, and social support needs. Results revealed difficulties in adjusting between the responsibilities of perceptually distinct on-shift and off-shift lives, and managing potential psychological distance that develops while workers are on site. Participants emphasised the importance of maintaining quality communication and support from family members. Workers and partners attempted to maintain mental health and well-being by regularly engaging with support networks, although many felt organisational support was tokenistic, stigmatised or lacking. Conclusions Recommendations for enhancing support provided by FIFO organisations are offered. In particular, organisations should emphasise the importance of good mental health and well-being, maintain transparency regarding potential challenges of FIFO lifestyles, and offer professional support for managing multiple social roles and effective communication.

2012-01-01

Background This study examines exposure to perceived discrimination and its association with depression among low-income, Latina male-to-female transgender women as well as evaluates the impact of sexual partner violence and mistreatment on depression. Methods A total of 220 Latina male-to-female transgender women who resided in Los Angeles, California, were recruited through community based organizations and referrals. Participants completed individual interviews using a structured questionnaire. Depressive symptoms were assessed using the Patient Health Questionnaire (PHQ-9). Perceived discrimination was assessed using a fifteen-item measure that was designed to assess the experiences of maltreatment of transgender individuals. Multinomial logistic regression was used to examine the association between perceived discrimination and depression after controlling for the presence of other variables. Results Of the sample, 35% reported significant depressive symptoms (PHQ-9 ≥ 15). Additionally, one-third of the participants indicated that in the two weeks prior to the interviews they had thought either of hurting themselves or that they would be better off dead. The extent of perceived discrimination in this population was extensive. Many of the participants experienced discrimination on a daily basis (14%) or at least once or twice a week (25%) as demonstrated by a positive response to at least 7 of 15 items in the measure of perceived discrimination. Almost six out of ten participants admitted that they had been victims of sexual partner violence. Those who reported more frequent discrimination were more likely to be identified with severe depression. There was also a notable association between self-reported history of sexual partner violence and depression severity. Conclusions A significant association between depression severity and perceived discrimination was identified. How exposure to discrimination leads to increased risk of mental health problems needs additional investigation. Models investigating the association between perceived discrimination and depression among transgender women should include sexual partner violence as a potential confounding variable. PMID:22894701

2015-12-01

Intimate partner violence (IPV) is one of the most common forms of violence against women worldwide. Among Mexican women, it is estimated that 15 to 71% have experienced physical or sexual abuse by an intimate male partner in their lifetime. This study examined the prevalence of four leading risk factors associated with IPV (alcohol consumption, education, socioeconomic status (SES), and gender roles) in adult women (n = 68) in a migrant farmworker community in México. Alcohol consumption among women was higher than the national average, and partner consumption was lower. Education level and SES were low, and women identified with a feminist ideology more than a traditional gender role. Results also revealed that 86.4% (n = 57) of participants identified violence against women as a common problem in the community, and the majority (94.0%, n = 62) of participants believe that IPV specifically is a problem within the community.

OBJECTIVE To examine in-depth the lives of women whose partners attempted to kill them, and to identify patterns that may aid in the clinician's ability to predict, prevent, or counsel about femicide or attempted femicide. DESIGN Qualitative analysis of 30 in-depth interviews. SETTING Six U.S. cities. PARTICIPANTS Thirty women, aged 17–54 years, who survived an attempted homicide by an intimate partner. RESULTS All but 2 of the participants had previously experienced physical violence, controlling behavior, or both from the partner who attempted to kill them. The intensity of the violence, control, and threats varied greatly, as did the number of risk factors measured by the Danger Assessment, defining a wide spectrum of prior abuse. Approximately half (14/30) of the participants did not recognize that their lives were in danger. Women often focused more on relationship problems involving money, alcohol, drugs, possessiveness, or infidelity, than on the risk to themselves from the violence. The majority of the attempts (22/30) happened around the time of a relationship change, but the relationship was often ending because of problems other than violence. CONCLUSIONS Clinicians should not be falsely reassured by a woman's sense of safety, by the lack of a history of severe violence, or by the presence of few classic risk factors for homicide. Efforts to reduce femicide risk that are targeted only at those women seeking help for violence-related problems may miss potential victims. PMID:14521640

The downside of Viagra: women's experiences and concerns.

2003-11-01

While much is known about the efficacy and safety of sexuopharmaceuticals used by men for the treatment of erectile difficulties, there remains a dearth of knowledge on the perspectives and experiences of their sexual partners. In particular, few studies have focused on the possible detrimental effects for women of Viagra use within a heterosexual relationship. In this paper we report on a qualitative study based in New Zealand, which involved in-depth interviews with 27 women whose partners used Viagra. A number of key dimensions were identified, three of which revealed issues and concerns for women regarding the use of Viagra by their male partners: the neglect of women by those producing and prescribing Viagra; the embodied relationship (which encompasses physical and psychosocial effects of Viagra use); and broader socio-cultural implications (e.g the impact of 'the culture of Viagra' on understandings about sexuality in older age, and on ideas about male and female sexuality). We argue that while previous medically-oriented research in this area has generally assumed an unproblematic link between Viagra use and the resumption of penetrative sex within heterosexual relationships, more attention needs to be paid to partners' perspectives and desires, and to the specific dynamics of any given relationship. Moreover, while the publicity surrounding Viagra may potentially facilitate more positive attitudes to sexuality in older age, it may also produce a societal expectation that 'healthy' and 'normal' life for older people requires the continuation of 'youthful' (energetic) sex lives focused on penetrative intercourse.

New partner proteins containing novel internal recognition motif for human Glutaminase Interacting Protein (hGIP)

Regulation of gene expression in cells is mediated by protein-protein, DNA-protein and receptor-ligand interactions. PDZ (PSD-95/Discs-large/ZO-1) domains are protein–protein interaction modules. PDZ-containing proteins function in the organization of multi-protein complexes controlling spatial and temporal fidelity of intracellular signaling pathways. In general, PDZ proteins possess multiple domains facilitating distinct interactions. The human Glutaminase Interacting Protein (hGIP) is an unusual PDZ protein comprising entirely of a single PDZ domain and plays pivotal roles in many cellular processes through its interaction with the C-terminus of partner proteins. Here, we report the identification by yeast two-hybrid screening of two new hGIP-interacting partners, DTX1 and STAU1. Both proteins lack the typical C-terminal PDZ recognition motif but contain a novel internal hGIP recognition motif recently identified in a phage display library screen. Fluorescence resonance energy transfer and confocal microscopy analysis confirmed the in vivo association of hGIP with DTX1 and STAU1 in mammalian cells validating the previous discovery of S/T-X-V/L-D as a consensus internal motif for hGIP recognition. Similar to hGIP, DTX1 and STAU1 have been implicated in neuronal function. Identification of these new interacting partners furthers our understanding of GIP-regulated signaling cascades and these interactions may represent potential new drug targets in humans.

Exposure to violence is traumatic and an important source of mental health disturbance, yet the factors associated with victimization remain incompletely understood. The aim of the present study was to investigate factors related to vulnerability to depression-like behaviors in females. An animal model of intimate partner violence, which was previously shown to produce long-lasting behavioral effects in females as a result of male partner aggression, was used. The associations among the degree of partner aggression, the long-term consequences on depressive-like behavior, and the impact of the anxious temperament of the female were examined. In a separate group, pre-selected neural markers were evaluated in the amygdala and the lateral septum of females. Expression was examined by analyses of targeted candidate genes, serotonin transporter (slc6a4), vasopressin receptor 1a, (avpr1a), and oxytocin receptor (oxtr). Structural equation modeling revealed that the female's temperament moderated depressive-like behavior that was induced by cohabitation aggression from the male partner. More specifically, increased floating in the forced swim test following male aggression was most apparent in females exhibiting more anxiety-like behavior (i.e., less open arm exploration in an elevated plus-maze) prior to the cohabitation. Aggression reduced slc6a4 levels in the lateral septum. However, the interaction between partner aggression and the anxious temperament of the female affected the expression of avpr1a in the amygdala. Although, aggression reduced levels of this marker in females with high anxiety, no such pattern was observed in females with low anxiety. These results identify important characteristics in females that moderate the impact of male aggression. Furthermore, these results provide potential therapeutic targets of interest in the amygdala and the lateral septum to help improve post-stress behavioral pathology and increase resilience to social adversity.

In response to the 2014-2016 Ebola virus disease (Ebola) epidemic in West Africa, CDC prepared for the potential introduction of Ebola into the United States. The immediate goals were to rapidly identify and isolate any cases of Ebola, prevent transmission, and promote timely treatment of affected patients. CDC's technical expertise and the collaboration of multiple partners in state, local, and municipal public health departments; health care facilities; emergency medical services; and U.S. government agencies were essential to the domestic preparedness and response to the Ebola epidemic and relied on longstanding partnerships. CDC established a comprehensive response that included two new strategies: 1) active monitoring of travelers arriving from countries affected by Ebola and other persons at risk for Ebola and 2) a tiered system of hospital facility preparedness that enabled prioritization of training. CDC rapidly deployed a diagnostic assay for Ebola virus (EBOV) to public health laboratories. Guidance was developed to assist in evaluation of patients possibly infected with EBOV, for appropriate infection control, to support emergency responders, and for handling of infectious waste. CDC rapid response teams were formed to provide assistance within 24 hours to a health care facility managing a patient with Ebola. As a result of the collaborations to rapidly identify, isolate, and manage Ebola patients and the extensive preparations to prevent spread of EBOV, the United States is now better prepared to address the next global infectious disease threat.The activities summarized in this report would not have been possible without collaboration with many U.S. and international partners (http://www.cdc.gov/vhf/ebola/outbreaks/2014-west-africa/partners.html).

Expedited partner therapy (EPT) for Chlamydia trachomatis (Ct) is the practice of providing Ct-infected patients with medication, or prescription (prescription-EPT) to deliver to their sex partners without first examining those partners. New York City (NYC) providers commonly use prescription-EPT, yet NYC pharmacists report only occasional receipt of EPT prescriptions. This project assessed the frequency of EPT prescriptions filled in 2 NYC neighborhoods. The 2 NYC facilities reporting the most frequent use of prescription-EPT were identified from Ct provider case reports and contacted to ascertain their EPT practices. Providers at the first facility (facility 1) prescribed two 1-g doses of azithromycin, including sex partner treatment on the index patient's electronic prescription. Providers at the second facility (facility 2) gave patients paper prescriptions for sex partners. We reviewed prescriptions filled in 2015 for azithromycin, 1 or 2 g at pharmacies near these facilities; prescriptions indicating partner therapy were classified "EPT prescriptions". Facility 1 providers submitted 112 Ct case reports indicating prescription-EPT, compared with 114 submitted by facility 2 providers. Twelve of 26 identified pharmacies agreed to participate. At 7 pharmacies near facility 1, we found 61 EPT prescriptions from facility 1 and 37 from other facilities. At 5 pharmacies near facility 2, we found only 1 EPT prescription from facility 2 and 3 from other facilities. Expedited partner therapy prescriptions were received in NYC pharmacies near to EPT-prescribing facilities, but with great variability and at a lower frequency than suggested by provider case reports. Provider EPT prescribing practices may impact the likelihood that partners receive medication and should be further evaluated.

Objectives. We estimated the frequency and examined the characteristics of intimate partner homicide and related deaths in 16 US states participating in the National Violent Death Reporting System (NVDRS), a state-based surveillance system. Methods. We used a combination of quantitative and qualitative methods to analyze NVDRS data from 2003 to 2009. We selected deaths linked to intimate partner violence for analysis. Results. Our sample comprised 4470 persons who died in the course of 3350 intimate partner violence–related homicide incidents. Intimate partners and corollary victims represented 80% and 20% of homicide victims, respectively. Corollary homicide victims included family members, new intimate partners, friends, acquaintances, police officers, and strangers. Conclusions. Our findings, from the first multiple-state study of intimate partner homicide and corollary homicides, demonstrate that the burden of intimate partner violence extends beyond the couple involved. Systems (e.g., criminal justice, medical care, and shelters) whose representatives routinely interact with victims of intimate partner violence can help assess the potential for lethal danger, which may prevent intimate partner and corollary victims from harm.

The Four Cs of disaster partnering: communication, cooperation, coordination and collaboration.

Public, nonprofit and private organisations respond to large-scale disasters domestically and overseas. Critics of these assistance efforts, as well as those involved, often cite poor interorganisational partnering as an obstacle to successful disaster response. Observers frequently call for 'more' and 'better' partnering. We found important qualitative distinctions existed within partnering behaviours. We identified four different types of interorganisational partnering activities often referred to interchangeably: communication, cooperation, coordination and collaboration-the Four Cs. We derived definitions of the Four Cs from the partnering literature. We then tested them in a case study of the response to the 2010 Haiti earthquake. We suggest that the Four Cs are distinct activities, that organisations are typically strong or weak in one or more for various reasons, and that the four terms represent a continuum of increased interorganisational embeddedness in partnering activities. © 2016 The Author(s).

To examine the views of educated people in Togo on the acceptability of criminal prosecution of a male partner for sexual transmission of infectious diseases (STIDs) to his female partner. 199 adults living in Kara, Togo judged acceptability of criminal prosecution for STID in 45 scenarios composed of combinations of five factors: (a) severity of disease; (b) awareness and communication of one's serological status; (c) partners' marital status; (d) number of sexual partners the female partner has and (e) male partner's subsequent attitude (supportive or not). Acceptability was lower (a) when the male partner decided to take care of his female partner he had infected than when he decided to leave, (b) when both partners were informed but decided not to take precautions than when none of them was informed or when only the male partner was informed and (c) when the female partner has had several male sexual partners than when she has had only one. Two qualitatively different views were identified. For 66% of participants, when the male partner accepts to take care of his partner, he should not be sued, except when he did not disclose his serological status. For 34%, when both partners were informed, the male partner should not be sued, irrespective of other circumstances. Regarding criminal prosecution for STID, most people in the sample endorsed the position of the Joint United Nations Programme on HIV/AIDS that urges governments not to apply criminal law to cases where sexual partners disclosed their status or were not informed of it.

Oxidative stress–induced assembly of PML nuclear bodies controls sumoylation of partner proteins

The promyelocytic leukemia (PML) protein organizes PML nuclear bodies (NBs), which are stress-responsive domains where many partner proteins accumulate. Here, we clarify the basis for NB formation and identify stress-induced partner sumoylation as the primary NB function. NB nucleation does not rely primarily on intermolecular interactions between the PML SUMO-interacting motif (SIM) and SUMO, but instead results from oxidation-mediated PML multimerization. Oxidized PML spherical meshes recruit UBC9, which enhances PML sumoylation, allow partner recruitment through SIM interactions, and ultimately enhance partner sumoylation. Intermolecular SUMO–SIM interactions then enforce partner sequestration within the NB inner core. Accordingly, oxidative stress enhances NB formation and global sumoylation in vivo. Some NB-associated sumoylated partners also become polyubiquitinated by RNF4, precipitating their proteasomal degradation. As several partners are protein-modifying enzymes, NBs could act as sensors that facilitate and confer oxidative stress sensitivity not only to sumoylation but also to other post-translational modifications, thereby explaining alterations of stress response upon PML or NB loss.

Sexual Orientation Disparities in Sexually Transmitted Infections: Examining the Intersection Between Sexual Identity and Sexual Behavior

Everett, Bethany G.

2013-01-01

The terms MSM (men who have sex with men) and WSW (women who have sex with women) have been used with increasing frequency in the public health literature to examine sexual orientation disparities in sexual health. These categories, however, do not allow researchers to examine potential differences in sexually transmitted infection (STI) risk by sexual orientation identity. Using data from the National Longitudinal Survey of Adolescent Health, this study investigated the relationship between self-reported STIs and both sexual orientation identity and sexual behaviors. Additionally, this study examined the mediating role of victimization and STI risk behaviors on the relationship between sexual orientation and self-reported STIs. STI risk was found to be elevated among heterosexual-WSW and bisexual women, whether they report same-sex partners or not, whereas gay-identified WSW were less likely to report an STI compared to heterosexual women with opposite sex relationships only. Among males, heterosexual-identified MSM did not have a greater likelihood of reporting an STI diagnosis; rather, STI risk was concentrated among gay and bisexual identified men who reported both male and female sexual partners. STI risk behaviors mediated the STI disparities among both males and females, and victimization partially mediated STI disparities among female participants. These results suggest that relying solely on behavior-based categories, such as MSM and WSW, may mischaracterize STI disparities by sexual orientation. PMID:22350122

The process involved in the identification and development of novel breakthrough medicines at big pharma has recently undergone significant changes, in part because of the extraordinary complexity that is associated with tackling diseases of high unmet need, and also because of the increasingly demanding requirements that have been placed on the pharmaceutical industry by investors and regulatory authorities. In addition, big pharma no longer have a monopoly on the tools and enabling technologies that are required to identify and discover new drugs, as many biotech companies now also have these capabilities. As a result, researchers at biotech companies are able to identify credible drug leads, as well as compounds that have the potential to become marketed medicinal products. This diversification of companies that are involved in drug discovery and development has in turn led to increased partnering interactions between the biotech sector and big pharma. This article examines how Merck and Co Inc, which has historically relied on a combination of internal scientific research and licensed products, has poised itself to become further engaged in partnering with biotech companies, as well as academic institutions, to increase the probability of success associated with identifying novel medicines to treat unmet medical needs--particularly in areas such as central nervous system disorders, obesity/metabolic diseases, atheroma and cancer, and also to cultivate its cardiovascular, respiratory, arthritis, bone, ophthalmology and infectious disease franchises.

Heterosexual College Students Who Hookup with Same-Sex Partners.

Individuals who identify as heterosexual but engage in same-sex sexual behavior fascinate both researchers and the media. We analyzed the Online College Social Life Survey dataset of over 24,000 undergraduate students to examine students whose last hookup was with a same-sex partner (N = 383 men and 312 women). The characteristics of a significant minority of these students (12% of men and 25% of women) who labelled their sexual orientation "heterosexual" differed from those who self-identified as "homosexual," "bisexual," or "uncertain." Differences among those who identified as heterosexual included more conservative attitudes, less prior homosexual and more prior heterosexual sexual experience, features of the hookups, and sentiments about the encounter after the fact. Latent class analysis revealed six distinctive "types" of heterosexually identified students whose last hookup was with a same-sex partner. Three types, comprising 60% of students, could be classified as mostly private sexual experimentation among those with little prior same-sex experience, including some who did not enjoy the encounter; the other two types in this group enjoyed the encounter, but differed on drunkenness and desire for a future relationship with their partner. Roughly, 12% could be classified as conforming to a "performative bisexuality" script of women publicly engaging in same-sex hookups at college parties, and the remaining 28% had strong religious practices and/or beliefs that may preclude a non-heterosexual identity, including 7% who exhibited "internalized heterosexism." Results indicate several distinctive motivations for a heterosexual identity among those who hooked up with same-sex partners; previous research focusing on selective "types" excludes many exhibiting this discordance.

With recent progress in the analysis of the salivary proteome, the number of salivary proteins identified has increased dramatically. However, the physiological functions of many of the newly discovered proteins remain unclear. Closely related to the study of a protein’s function is the identification of its interaction partners. Although in saliva some proteins may act primarily as single monomeric units, a significant percentage of all salivary proteins, if not the majority, appear to act in complexes with partners to execute their diverse functions. Coimmunoprecipitation (Co-IP) and pull-down assays were used to identify the heterotypic complexes between histatin 5, a potent natural antifungal protein, and other salivary proteins in saliva. Classical protein–protein interaction methods in combination with high-throughput mass spectrometric techniques were carried out. Co-IP using protein G magnetic Sepharose TM beads suspension was able to capture salivary complexes formed between histatin 5 and its salivary protein partners. Pull-down assay was used to confirm histatin 5 protein partners. A total of 52 different proteins were identified to interact with histatin 5. The present study used proteomic approaches in conjunction with classical biochemical methods to investigate protein–protein interaction in human saliva. Our study demonstrated that when histatin 5 is complexed with salivary amylase, one of the 52 proteins identified as a histatin 5 partner, the antifungal activity of histatin 5 is reduced. We expected that our proteomic approach could serve as a basis for future studies on the mechanism and structural-characterization of those salivary protein interactions to understand their clinical significance.

The changing landscape of HIV prevention in the United States underscores the need to improve our ability to efficiently reach HIV-positive men who have sex with men (MSM) who engage in behaviors that could transmit HIV. We examined the prevalence of anal intercourse (AI) without condoms with HIV-negative or unknown serostatus partners ("at-risk partners") among 1319 HIV-positive adult male members of a sexual networking Web site for MSM. Sexual behaviors and substance use were measured over a 60-day recall period. Logistic regression was used to identify correlates of insertive and receptive AI without condoms with at-risk partners. Approximately 25% of the men had been diagnosed as having HIV 12 months or less before study enrollment. Overall, 32% of men engaged in AI without condoms with at-risk partners. Multiple logistic regression identified behavioral predictors of insertive AI without condoms with at-risk partners, including HIV diagnosis within the last 12 months, sex with multiple male partners, substance use in conjunction with sex, and use of phosphodiesterase type 5 inhibitors. Receptive AI without condoms with at-risk partners was associated with younger age (19-24 years), residing outside metropolitan cities, substance use in conjunction with sex, and having multiple male partners. High levels of sexual risk were found among these MSM. Increased Internet-based HIV prevention marketing efforts and prevention strategies should be considered to efficiently reach HIV-positive MSM who engage in serodiscordant AI without condoms.

Network analysis is useful for understanding sexual transmission of HIV and other sexually transmitted infections. We conducted egocentric and affiliation network analysis among HIV-infected young black men who have sex with men (MSM) in the Jackson, Mississippi, area to understand networks and connectedness of this population. We interviewed 22 black MSM aged 17 to 25 years diagnosed as having HIV in 2006 to 2008. Participants provided demographic and geographic information about each sex partner during the 12 months before diagnosis and identified venues where they met these partners. We created affiliation network diagrams to understand connectedness of this population and identify venues that linked participants. The median number of partners reported was 4 (range, 1-16); a total of 97 partners (88 of whom were male) were reported. All but 1 participant were connected through a network of venues where they had met partners during the 12 months before diagnosis. Three venues were named as places for meeting partners by 13 of 22 participants. Participants reported having partners from all regions of Mississippi and 5 other states. HIV-infected young black MSM in this analysis were linked by a small number of venues. These venues should be targeted for testing and prevention interventions. The pattern of meeting sex partners in a small number of venues suggests densely connected networks that propagate infection. This pattern, in combination with sexual partnerships with persons from outside Jackson, may contribute to spread of HIV and other sexually transmitted infections into or out the Jackson area.

Family caregivers play an important role in caring for patients with advanced cancer. To become competent, individuals must draw on and mobilise an adequate combination of resources. Our goal was to identify the skills developed by caregivers of patients with advanced cancer and the associated resources mobilised. We chose to do it with partners of patients with colon cancer. The study used a cross-sectional qualitative design based on 20 individual interviews and a focus group. Partners were recruited from patients treated in three hospitals of France. Semi-structured interviews were conducted until data saturation was achieved. Each interview was transcribed verbatim, and thematic analyses were performed to extract significant themes and subthemes. Results from the individual and focus group interviews showed that the skills implemented by the partners (in domains of social relationships and health, domestic, organisational, emotional and well-being dimensions) were singular constructs, dependant on if resources (personal, external and schemes) may have been missing and insufficient. In addition, partners may have had these resources but not mobilised them. The identification of the skills and associated resources could allow healthcare professionals better identifying and understanding of the difficulties met by partners in taking care of patients. This could enable them to offer appropriate support to help the caregivers in their accompaniment.

A recent EAST-supported, multicenter trial demonstrated a similar rate of intimate partner and sexual violence (IPSV) between male and female trauma patients, regardless of mechanism. Our objective was to perform a subgroup analysis of our affected male cohort as this remains an understudied group in the trauma literature. We conducted a recent EAST-supported, cross-sectional, multicenter trial over one year (03/15-04/16) involving four Level I trauma centers throughout the United States. We performed universal screening of adult trauma patients using the validated HITS (Hurt, Insult, Threaten, Scream) and SAVE (sexual violence) screening surveys. Risk factors for male patients were identified. Chi-squared test compared categorical variables with significance at p<0.05. Parametric data is presented as mean +/-standard deviation. A total of 2,034 trauma patients were screened, of which 1,281 (63%) were men. Of this cohort, 119 men (9.3%) screened positive for intimate partner violence, 14.1% for IPSV and 6.5% for sexual violence. On categorical analysis of the HITS screen, the proportion of men that were physically hurt was 4.8% compared to 4.3% for women (p = 0.896). A total of 4.8% of men screened positive for both intimate partner and sexual violence. The total proportion of men who presented with any history of intimate partner violence, sexual violence or both (IPSV) was 15.8%. More men affected by penetrating trauma screened positive for IPSV (p < 0.00001). IPSV positivity in men was associated with mental illness, substance abuse, and trauma recidivism. One out of every twenty men that present to trauma centers is a survivor of both intimate partner and sexual violence, with one out of every six men experiencing some form of violence. Men are at similar risk for physical abuse as women when this intimate partner violence occurs. IPSV is associated with penetrating trauma in men. Support programs for this population may potentially impact associated mental illness, substance abuse, trauma recidivism and even societal-level violence. III STUDY TYPE: Diagnostic.

Inequalities in the psychological well-being of employed, single and partnered mothers: the role of psychosocial work quality and work-family conflict

PubMed Central

2010-01-01

Background A large body of international research reveals that single mothers experience poorer mental health than their partnered counterparts, with socioeconomic disadvantage identified as an important contributory factor in understanding this health disparity. Much less research, however, has focused specifically on the psychological well-being of single mothers who are employed, despite their growing presence in the labor force. Of the research which has considered employment, the focus has been on employment status per se rather than on other important work-related factors which may impact psychological health, such as psychosocial work quality and work-family conflict. The aim of this study was to: (1) compare employed single mothers and employed partnered mothers on measures of psychological distress, psychosocial work quality and work-family conflict; and (2) explore the potential role of work-family conflict and psychosocial work quality as explanations for any observed differences in psychological distress based on partner status. Method Analysis of data obtained from a cross-sectional telephone survey of employed parents in a mid-sized Western Canadian city. Analyses were based on 674 employed mothers (438 partnered and 236 single), who were 25-50 years old, with at least one child in the household. Results Compared to employed single mothers, employed partnered mothers were older, had more education and reported fewer hours of paid work. Single mothers reported higher levels of psychological distress, financial hardship, work-family conflict and poor psychosocial work quality. Statistical adjustment for income adequacy, psychosocial work quality and work-family conflict each independently resulted in single motherhood no longer being associated with psychological distress. Conclusions While single employed mothers did experience higher levels of psychological distress than their partnered counterparts, differences between these groups of women in income adequacy, psychosocial work quality, and work-family conflict were found to explain this relationship. Future research employing a longitudinal design and subject to lower selection biases is required to tease out the interrelationship of these three life strains and to point to the most appropriate economic and social policies to support single mothers in the workforce.

The authors examine respondents' potential reactions to the suggestion of condom usage by and to their sex partner. Results indicate that when a sex partner suggests condom use, individuals may react with a feeling of shared responsibility and/or look favorably upon the suggesting partner. In contrast, persons who suggest condom usage may be questioning their partner's past and envisioning a short-term relationship. The effects of individual-difference variables on feelings about condom usage are described and implications for marketing are delineated.

MTAP deletion confers enhanced dependency on the PRMT5 arginine methyltransferase in cancer cells | Office of Cancer Genomics

Cancer.gov

The discovery of cancer dependencies has the potential to inform therapeutic strategies and to identify putative drug targets. Integrating data from comprehensive genomic profiling of cancer cell lines and from functional characterization of cancer cell dependencies, we discovered that loss of the enzyme methylthioadenosine phosphorylase (MTAP) confers a selective dependence on protein arginine methyltransferase 5 (PRMT5) and its binding partner WDR77. MTAP is frequently lost due to its proximity to the commonly deleted tumor suppressor gene, CDKN2A.

Objectives. We examined associations between partner types (categorized as main, casual, or commercial) and sexual risk behaviors of sexually active male-to-female (transgender female) youths. Methods. We interviewed 120 transgender female youths aged 15 to 24 years recruited from clinics, community-based agencies, club and bar venues, referrals, and the streets of Los Angeles, California, and Chicago, Illinois. Results. Sexual risk behaviors varied by partner type. Transgender female youths were less likely to use condoms during receptive anal intercourse with their main partner and were less likely to use condoms with a main partner while under the influence of substances. Youth participants were also more likely to talk to a main partner about their HIV status. Our data identified no demographic or social factors that predicted condom use during receptive anal intercourse by partner type. Conclusions. Research and interventions that focus on understanding and mitigating risk behaviors by partner type, especially those that tackle the unique risks incurred with main partners, may make important contributions to risk reduction among transgender female youths.

Research on sexual-partner type focuses mostly on "main" and "casual" partner categories. The literature indicates that adolescent girls are less likely to use condoms with main partners, and more likely to use condoms with casual partners. Adolescent mothers may have different types of sexual partners than other adolescent girls. The purpose of this study was to explore and describe the range of male sexual partner types reported by Black adolescent mothers. This study was a qualitative description of the perspectives of Black, predominantly African-American, mothers (n=31). Data were generated using focus groups and interviews. The participants' ages ranged from 15-19 years. A semi-structured qualitative questioning guide was used to stimulate focused discussions. Transcribed data were analyzed using qualitative content analysis. The range of sexual partner types of the women were reflected in three themes (1) All main partners are not created equal; (2) They're not casual partners because there are strings attached; (3) "Wham, bam, thank you ma'am:" No strings attached. Nine partner types were identified under these three themes, including a "baby daddy" partner. The partner-types of Black adolescent mothers are more robust than the "main" and "casual" partner categories typically referenced in the research literature. The range of sex partners includes the birth fathers of their children. Clinicians and researchers must consider how co-parenthood status is used in the construction of the "baby daddy" partner and what implications this unique sexual partner type may have on risk reduction behaviors such as condom use.

The paper examines potential origins of automatic (i.e., unconscious) attitudes toward one’s marital partner. It tests the hypothesis that early experiences in conflict-of-interest situations predict one’s later automatic inclination to approach (or avoid) the partner. A longitudinal study linked daily experiences in conflict-of-interest situations in the initial months of new marriages to automatic evaluations of the partner assessed four years later using the Implicit Associations Test. The results revealed that partners who were initially (1) treated less responsively and (2) evidenced more self-protective and less connectedness-promoting “if-then” contingencies in their thoughts and behavior later evidenced less positive automatic partner attitudes. However, these factors did not predict changes in love, satisfaction, or explicit beliefs about the partner. The findings hint at the existence of a “smart” relationship unconscious that captures behavioral realities conscious reflection can miss. PMID:20526450

Using data from the North Carolina Violent Death Reporting System and other sources, we examined ecologic relationships between county (n=100) disadvantage and intimate partner homicide (IPH), variability by victim gender and county urbanicity, and potential mediators. County disadvantage was related to female-victim homicide only in metropolitan counties (incidence rate ratio [IRR] 1.25); however, disadvantage was associated with male-victim IPH regardless of county urbanicity (IRR 1.17). None of the potential intervening variables examined (shelter availability, intimate partner violence services’ funding), was supported as a mediator. Results suggest disparities across North Carolina counties in IPH according to county disadvantage. Future research should explore other potential mediators (i.e., service accessibility and law enforcement responses), as well as test the robustness of findings using additional years of data.

According to 2011 data, nearly one in four women and one in seven men in the United States experience severe physical violence by an intimate partner, creating a public health burden requiring population-level solutions. To prevent intimate partner violence (IPV) before it occurs, the CDC developed Domestic Violence Prevention Enhancements and Leadership Through Alliances, Focusing on Outcomes for Communities United with States to identify promising community- and societal-level prevention strategies to prevent IPV. The program funds 10 state domestic violence coalitions for 5 years to implement and evaluate programs and policies to prevent IPV by influencing the environments and conditions in which people live, work, and play. The program evaluation goals are to promote IPV prevention by identifying promising prevention strategies and describing those strategies using case studies, thereby creating a foundation for building practice-based evidence with a health equity approach.

Mechanisms of input and output synaptic specificity: finding partners, building synapses, and fine-tuning communication.

For most neurons to function properly, they need to develop synaptic specificity. This requires finding specific partner neurons, building the correct types of synapses, and fine-tuning these synapses in response to neural activity. Synaptic specificity is common at both a neuron's input and output synapses, whereby unique synapses are built depending on the partnering neuron. Neuroscientists have long appreciated the remarkable specificity of neural circuits but identifying molecular mechanisms mediating synaptic specificity has only recently accelerated. Here, we focus on recent progress in understanding input and output synaptic specificity in the mammalian brain. We review newly identified circuit examples for both and the latest research identifying molecular mediators including Kirrel3, FGFs, and DGLα. Lastly, we expect the pace of research on input and output specificity to continue to accelerate with the advent of new technologies in genomics, microscopy, and proteomics.

Daily reports of intimate partner verbal aggression by self and partner: Short-term consequences and implications for measurement.

PubMed

Derrick, Jaye L; Testa, Maria; Leonard, Kenneth E

2014-10-01

Agreement within couples regarding the occurrence of aggression is surprisingly low. Survey research often collapses across partners' reports to create a pooled estimate of aggression in the relationship. This method ignores possible differences in partners' perceptions of the event, potentially weakening researchers' ability to detect consequences of aggression. The current study examines both partners' reports of verbal aggression to determine whether aggression reported by only one partner influences both partners' short-term outcomes. We used a 56-day daily diary to examine the effect of verbal aggression on short-term negative outcomes. We examined whether aggression reported by either partner is sufficient to predict consequences for both partners, or if an individual must report aggression to experience consequences. Victims' reports of receiving verbal aggression were a better predictor of next day victim consequences than perpetrators' reports. Perpetrators' reports of perpetrating verbal aggression were a better predictor of next day perpetrator consequences than victims' reports. Days when partners agreed that aggression had occurred generally predicted the worst outcomes. People's own reports of verbal aggression are the best predictor of short-term consequences. Pooling partner reports of aggression may make it more difficult to understand the consequences of intimate partner aggression.

Partner communication about HIV sexual risk behaviors represents a key area of epidemiologic and social importance in terms of infection acquisition and potential for tailored interventions. Nevertheless, disclosing sexual risk behaviors often presents myriad challenges for marginalized couples who engage in stigmatized behaviors. Using qualitative data from a social epidemiology study of risk for HIV and other sexually transmitted infections (STIs) among female sex workers and their intimate, non-commercial male partners along the Mexico-U.S. border, we examined both partners' perspectives on sex work and the ways in which couples discussed associated HIV/STI risks in their relationship. Our thematic analysis of individual and joint interviews conducted in 2010 and 2011 with 44 couples suggested that broader contexts of social and economic inequalities profoundly shaped partner perspectives of sex work. Although couples accepted sex work as an economic contribution to the relationship in light of limited alternatives and drug addiction, it exacted an emotional toll on both partners. Couples employed multiple strategies to cope with sex work, including psychologically disconnecting from their situation, telling "little lies," avoiding the topic, and to a lesser extent, superficially discussing their risks. While such strategies served to protect both partners' emotional health by upholding illusions of fidelity and avoiding potential conflict, non-disclosure of risk behaviors may exacerbate the potential for HIV/STI acquisition. Our work has direct implications for designing multi-level, couple-based health interventions. Copyright © 2013 Elsevier Ltd. All rights reserved.

Limited research has investigated the perceived influence of sexually explicit online media (SEOM) on body satisfaction and partner expectations of men who have sex with men (MSM). Semi-structured qualitative interviews were conducted with 16 MSM, covering the perceived influence of MSM-specific SEOM. All nine men who broached the topics of body satisfaction and partner expectations reported that MSM-specific SEOM set unreasonably high physical appearance expectations for themselves and/or their potential partners. Although MSM-specific SEOM might be negatively affecting body satisfaction and partner expectations among MSM, its ubiquity may make it a useful tool to support body positivity.

A public-private partnership (PPP) is an essential component of the Dutch community-based approach toward overweight prevention, Youth on Healthy Weight (JOGG). Beginning in 2010, 25 Dutch municipalities have implemented JOGG, but little is known about determinants of successful partnerships. This study aims to identify these determinants to guide other municipalities or communities in creating successful partnerships. Semistructured interviews were held in Veghel, a town in the southeast of the Netherlands, with private (n=7) and public (n=5) partners from the PPP involved in JOGG. We developed a themes and topics list that fit the purpose of our study. The interviews focused on the formation, functioning, and output of the partnership. Recruitment of partners was facilitated by using preexisting networks. Corporate social responsibility, belief in the JOGG approach, importance of the health issue, and strengthened contacts with other partners were important motivations for partners to participate. In addition to partnership functioning and output, enthusiastic and decisive management, shared commitment, joint responsibility, and effective internal communication were important to the partners, as were clear goals and concrete actions to achieve these goals. To create successful partnerships, the program and its goals should appeal to the motivations of the partners. Involving partners in defining local program objectives can help to create shared commitment and joint responsibility. Further evaluation of partnerships' impact on achieving program goals is a subsequent step to be taken to identify long-term determinants of successful PPPs.

2013-01-01

Intimate partner violence (IPV) is defined as an actual or threatened abuse by an intimate partner that may be physical, sexual, psychological, or emotional in nature. Each year approximately 1.5 million women in the United States report some form of sexual or physical assault by an intimate partner; it is estimated that approximately 324,000 women are pregnant when violence occurs. Pregnancy may present a unique opportunity to identify and screen for patients experiencing IPV. This article provides health care practitioners and clinicians with the most current valid assessment and screening tools for evaluating pregnant women for IPV. PMID:24920977

Chinese rare earth export policies currently result in accelerating its depletion. Thus adopting an optimal export trade selection strategy is crucial to determining and ultimately identifying the ideal trading partners. This paper introduces a multi-attribute decision-making methodology which is then used to select the optimal trading partner. In the method, an evaluation criteria system is established to assess the seven top trading partners based on three dimensions: political relationships, economic benefits and industrial security. Specifically, a simple additive weighing model derived from an additive utility function is utilized to calculate, rank and select alternatives. Results show that Japan would be the optimal trading partner for Chinese rare earths. The criteria evaluation method of trading partners for China's rare earth exports provides the Chinese government with a tool to enhance rare earth industrial policies. PMID:25051534

Benefits of positive relationship experiences for avoidantly attached individuals.

PubMed

Stanton, Sarah C E; Campbell, Lorne; Pink, Jennifer C

2017-10-01

Attachment avoidance is characterized by discomfort with closeness and a reluctance to develop intimacy with romantic partners, which contribute to heightened general negativity and lower satisfaction and self-disclosure in and out of their relationships. Recent research, however, has begun to uncover circumstances in which romantic partners and positive relationships buffer more avoidantly attached individuals against deleterious individual and relationship outcomes. Across 3 studies, using a multimethod approach encompassing both experimental and dyadic longitudinal diary methods, we investigated the effects of positive, intimacy-related relationship experiences on more avoidant persons' positive and negative affect, relationship quality, self-disclosure, and attachment security immediately and over time. Results revealed that more avoidant individuals exhibit a reduction of general negative affect in particular (Studies 1-2) and report greater relationship quality (Studies 2-3) in response to positive relationship experiences, and, following intimacy-promoting activities with their partner, engage in greater self-disclosure over time and demonstrate decreased attachment avoidance 1 month later (Study 3). These findings identify novel circumstances in which more avoidant persons' negative expectations of relationships may be countered, and suggest that relatively simple techniques can have potentially important short- and long-term implications for more avoidant individuals and their relationships.

Maternal exposure to significant prenatal stress can negatively affect infant neurobiological development and increase the risk for developmental and health disturbances. These effects may be pronounced in low SES and ethnic minority families. We explored prenatal partner support as a buffer of the impact of prenatal stress on cortisol reactivity of infants born to low-income Mexican American women. Women (N=220; age 18–42; 84% Spanish-speaking; 89% foreign born; modal family income $10,000–$15,000) reported on economic stress and satisfaction with spousal/partner support during the prenatal period (26–38 weeks gestation), and infant salivary cortisol reactivity to mildly challenging mother-infant interaction tasks was assessed at women’s homes at six weeks postpartum. Multilevel models estimated the interactive effect of prenatal stress and partner support on cortisol reactivity, controlling for covariates and potential confounds. Infants born to mothers who reported high prenatal stress and low partner support exhibited higher cortisol reactivity relative to those whose mothers reported high support or low stress. The effects did not appear to operate through birth outcomes. For low-income Mexican American women, partner support may buffer the impact of prenatal stress on infant cortisol reactivity, potentially promoting more adaptive infant health and development.

To investigate the influence of partners on alcohol consumption in pregnant women within the context of other factors. A Dutch nationwide online cross-sectional study among 158 pregnant women and their partners was conducted. To identify correlates of prenatal alcohol use, including perceived and reported partner norm (i.e. partner's belief regarding acceptability of prenatal alcohol use), partner modeling (i.e. partner's alcohol use during the woman's pregnancy) and partner support (i.e. partner's help in abstaining from alcohol during pregnancy), independent sample T-tests and Chi square tests were conducted. Correlation analyses tested the relationship between perceived and reported partner influence. Multivariate logistic hierarchical regression analyses tested the independent impact of partner's perceived and reported influence next to other correlates from the I-Change Model. Pregnant women who consumed alcohol perceived a weaker partner norm (p < 0.001) and less partner modeling (p < 0.05), with the partner reporting a weaker norm (p < 0.001), more drinking days per week (p < 0.05) and weaker support (p < 0.05). Perceived and reported partner norm, modeling and support were positively related (respectively p < 0.01, p < 0.01 and p < 0.05). The multivariate analyses demonstrated that pregnant women with a higher education who perceived lower severity of harm due to prenatal alcohol use and a weaker partner norm were more likely to use alcohol (R(2) = 0.42). This study demonstrated that perceived partner norm was the most critical of the constructs of perceived and reported partner influences in explaining prenatal alcohol use.

Student and service user involvement is recognised as an important factor in creating interprofessional education (IPE) opportunities. We used a team-based learning approach to bring together undergraduate health professional students, early career professionals (ECPs), public partners, volunteers, and carers to explore learning partnerships. Influenced by evaluative inquiry, this qualitative study used a free text response to allow participants to give their own opinion. A total of 153 participants (50 public partners and 103 students and professionals representing 11 healthcare professions) took part. Participants were divided into mixed groups of six (n = 25) and asked to identify areas where students, professionals, and public could work together to improve health professional education. Each group documented their discussions by summarising agreed areas and next steps. Responses were collected and transcribed for inductive content analysis. Seven key themes (areas for joint working) were identified: communication, public as partners, standards of conduct, IPE, quality improvement, education, and learning environments. The team-based learning format enabled undergraduate and postgraduate health professionals to achieve consensus with public partners on areas for IPE and collaboration. Some of our results may be context-specific but the approach is generalisable to other areas.

Parenting a child through cancer is a distressing experience, and a subgroup of parents report negative long-term psychological consequences years after treatment completion. However, there is a lack of evidence-based psychological interventions for parents who experience distress in relation to a child's cancer disease after end of treatment. One aim of this study was to develop an internet-administered, cognitive behavior therapy-based, psychological, guided, self-help intervention (ENGAGE) for parents of children previously treated for cancer. Another aim was to identify acceptable procedures for future feasibility and efficacy studies testing and evaluating the intervention. Participatory action research methodology was used. The study included face-to-face workshops and related Web-based exercises. A total of 6 parents (4 mothers, 2 fathers) of children previously treated for cancer were involved as parent research partners. Moreover, 2 clinical psychologists were involved as expert research partners. Research partners and research group members worked collaboratively throughout the study. Data were analyzed iteratively using written summaries of the workshops and Web-based exercises parallel to data collection. A 10-week, internet-administered, cognitive behavior therapy-based, psychological, guided, self-help intervention (ENGAGE) was developed in collaboration with parent research partners and expert research partners. The content of the intervention, mode and frequency of e-therapist support, and the individualized approach for feedback were modified based on the research partner input. Shared solutions were reached regarding the type and timing of support from an e-therapist (eg, initial video or telephone call, multiple methods of e-therapist contact), duration and timing of intervention (eg, 10 weeks, 30-min assessments), and the removal of unnecessary support functions (eg, removal of chat and forum functions). Preferences for study procedures in future studies testing and evaluating the intervention were discussed; consensus was not reached for all aspects. To the best of our knowledge, this study is the first use of a participatory action research approach to develop a psychological intervention for parents of children previously treated for cancer and to identify acceptable study procedures. Involvement of parents with lived experience was vital in the development of a potentially relevant and acceptable intervention for this population. ©Anna Wikman, Laura Kukkola, Helene Börjesson, Martin Cernvall, Joanne Woodford, Helena Grönqvist, Louise von Essen.

Theory and research on HIV and among men who have sex with men (MSM) have long suggested the importance of non-residential locations in defining structural exposures. Despite this, most studies within these fields define place as a residential context, neglecting the potential influence of non-residential locations on HIV-related outcomes. The concept of activity spaces, defined as a set of locations to which an individual is routinely exposed, represents one theoretical basis for addressing this potential imbalance. Using a one-time online survey to collect demographic, behavioral, and spatial data from MSM, this paper describes activity spaces and examines correlates of this spatial variation. We used latent class analysis to identify categories of activity spaces using spatial data on home, routine, potential sexual risk, and HIV prevention locations. We then assessed individual and area-level covariates for their associations with these categories. Classes were distinguished by the degree of spatial variation in routine and prevention behaviors (which were the same within each class) and in sexual risk behaviors (i.e., sex locations and locations of meeting sex partners). Partner type (e.g. casual or main) represented a key correlate of the activity space. In this early examination of activity spaces in an online sample of MSM, patterns of spatial behavior represent further evidence of significant spatial variation in locations of routine, potential HIV sexual risk, and HIV prevention behaviors among MSM. Although prevention behaviors tend to have similar geographic variation as routine behaviors, locations where men engage in potentially high-risk behaviors may be more spatially focused for some MSM than for others.

Science, technology, engineering, and math (STEM) are growing fields that provide job stability, financial security, and health prosperity for professionals in these fields. Unfortunately, females are underrepresented in STEM, which is potentially both a consequence and precipitant of gender inequity in the United States. In addition to the financial and health benefits, increasing the number of girls and women in STEM fields may also indirectly prevent and/or reduce teen dating violence and intimate partner violence by: (1) increasing women's financial independence, thereby reducing dependence on potentially abusive partners; (2) decreasing household poverty and financial stress, which may lead to reductions in relationship discord; and (3) increasing attitudes and beliefs about women as equals, thereby increasing gender equity. In this commentary, we discuss the potential role of primary and secondary school STEM programs in reducing violence against women. We review the literature on existing evaluations of STEM programs for educational outcomes, discuss the limitations of these evaluations, and offer suggestions for future research.

A detailed understanding of intentions and practices related to partner notification (PN) following STI diagnosis can improve control strategies. We assessed participant-level and partner-level factors guiding notification behaviour among men who have sex with men and/or with transgender women (MSM-TW) in Lima, Peru, including discordances between anticipated and actual notification. Men newly diagnosed with gonorrhoea, chlamydia and/or syphilis between 2012 and 2014 reported recent partners' characteristics, anticipated PN practices, and actual PN outcomes following diagnosis. Generalised estimating equation Poisson regression analyses assessed factors guiding PN outcomes. Participants (n=150) predominantly identified as homosexual (70%) and moderno (versatile sexual role, 55%); 55% of partners (n=402) were casual. Among all sexual partners, 35% were notified of the STI diagnosis, though only 51% of predicted PN occurred and 26% of actual notifications were unanticipated. 47% of participants notified no partners, while 24% notified all partners. PN was more common with stable versus casual (adjusted prevalence ratio (aPR), 95% CI: 0.53, 0.39 to 0.73) or commercial (aPR, 95% CI: 0.38, 0.12 to 1.21) partners, and among participants who perceived PN as normative among their peers (aPR, 95% CI: 1.96, 1.37 to 2.82). A trend towards greater notification following condom-protected intercourse was observed (aPR, 95% CI: 1.33, 0.98 to 1.81). PN frequency did not differ by type of STI diagnosed.Anticipated notification predicted actual notification (aPR, 95% CI: 1.67, 1.19 to 2.33) only imperfectly: 81 (54%) participants' PN practices did not match their anticipated behaviour. Successful notification despite anticipated silence (40 participants, 63 partners) was associated with stable partnerships and a normative perception of PN. Non-notification despite intention (43 participants, 73 partners) frequently occurred among participants reporting exclusively oral sex with the partner or with partners identified as activo (insertive role). Anticipated notification imperfectly reflects actual PN behaviour. Future interventions to improve PN among MSM-TW in Peru need to acknowledge partnership contexts. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Syntrophic growth of Desulfovibrio alaskensis requires genes for H2 and formate metabolism as well as those for flagellum and biofilm formation.

In anaerobic environments, mutually beneficial metabolic interactions between microorganisms (syntrophy) are essential for oxidation of organic matter to carbon dioxide and methane. Syntrophic interactions typically involve a microorganism degrading an organic compound to primary fermentation by-products and sources of electrons (i.e., formate, hydrogen, or nanowires) and a partner producing methane or respiring the electrons via alternative electron accepting processes. Using a transposon gene mutant library of the sulfate-reducing Desulfovibrio alaskensis G20, we screened for mutants incapable of serving as the electron-accepting partner of the butyrate-oxidizing bacterium, Syntrophomonas wolfei. A total of 17 gene mutants of D. alaskensis were identified as incapable of serving as the electron-accepting partner. The genes identified predominantly fell into three categories: membrane surface assembly, flagellum-pilus synthesis, and energy metabolism. Among these genes required to serve as the electron-accepting partner, the glycosyltransferase, pilus assembly protein (tadC), and flagellar biosynthesis protein showed reduced biofilm formation, suggesting that each of these components is involved in cell-to-cell interactions. Energy metabolism genes encoded proteins primarily involved in H2 uptake and electron cycling, including a rhodanese-containing complex that is phylogenetically conserved among sulfate-reducing Deltaproteobacteria. Utilizing an mRNA sequencing approach, analysis of transcript abundance in wild-type axenic and cocultures confirmed that genes identified as important for serving as the electron-accepting partner were more highly expressed under syntrophic conditions. The results imply that sulfate-reducing microorganisms require flagellar and outer membrane components to effectively couple to their syntrophic partners; furthermore, H2 metabolism is essential for syntrophic growth of D. alaskensis G20.

Sexually transmitted infection (STI) affects the reproductive health of both men and women worldwide. Condoms are important part of the available preventive strategies for STI control. The lack of proper risk-perception continues to impede women's ability to negotiate condom use with their partners. This paper is the outcome of secondary analysis of data collected in a cross-sectional survey that explored the perception of risk of STI and its influence on condom use among 504 pregnant women attending antenatal clinic at two health facilities in the Kintampo North Municipality. Consecutively, three Focus Group Discussions were conducted among 22 pregnant women which was analyzed using thematic analysis technique. Multivariate logistic regression analysis was used to identify possible predictors of condom use and risk of STI. Respondents mean age was 26.0 ± 5.9 years. 47% of respondents self-identified themselves as high risk for contracting STI, 50% of whom were married. High risk status (OR = 2.1, 95% CI: 1.1–4.4), ability to ask for condoms during sex (OR = 0.3, 95% CI: 0.1–0.73), and partner's approval of condom use (OR = 0.2, 95% CI: 0.01–0.05) were independent predictors of condom use. Condom use (OR 2.9 (1.5–5.7); p = 0.001) and marital status (engaged, OR 2.6 (1.5–4.5); p = 0.001) were independent predictors of risk of STI. Women who self-identified themselves as high risk for STI successfully negotiated condom use with their partners. This is however influenced by partner's approval and ability to convince partner to use condoms. Self-assessment of STI risk by women and the cooperation of male partners remain critical.

Background Hostage-taking, an overlooked phenomenon in public health, constitutes a severe form of intimate partner violence and may be a precursor to female homicide within relationships characterized by substance use. Criminal justice studies indicate that most hostage incidents are male-driven events with more than half of all cases associated with a prior history of violence and substance use. Methamphetamine use increases a woman’s risk of partner violence, with methamphetamine-using individuals being up to nine times more likely to commit homicide. As homicide is the most lethal outcome of partner violence and methamphetamine use, this study aims to characterize the potential role of hostage-taking within these intersecting epidemics. Methods Methamphetamine-using women enrolled in an HIV behavioural intervention trial (FASTLANE-II) who reported experiences of partner violence were purposively selected to participate in qualitative sub-studies (Women’s Study I & II). Twenty-nine women, ages 26–57, participated in semi-structured interviews that discussed relationship dynamics, partner violence, drug use and sexual practices. Results Findings indicated four cases of women being held hostage by a partner, with two women describing two separate hostage experiences. Women discussed partner jealousy, drug withdrawal symptoms, heightened emotional states from methamphetamine use, and escalating violent incidents as factors leading up to hostage-taking. Factors influencing lack of reporting incidents to law enforcement included having a criminal record, fear of partner retaliation, and intentions to terminate the relationship while the partner is incarcerated. Conclusion Educating women on the warning signs of hostage-taking within the context of methamphetamine use and promoting behaviour change among male perpetrators can contribute to reducing the risk of homicide. Furthermore, bridging the gap between health services and law enforcement agencies and providing comprehensive services that address the needs of methamphetamine-using women in violent relationships can prevent or minimize potential harm to vulnerable women.

Based on a theory of intervention as a complex action system, analyze collaboration among partners in Montréal's sexually transmitted and blood-borne infections (STBBI) prevention program to identify main operations problems and possible scenarios for change to achieve better outcomes. A descriptive study was conducted using three data sources - public policies and programs, system management documents, and interviews with three types of partners. The results were validated with stakeholders. Five main operations problems affecting the capacity of the system to provide expected services were identified, as well as strategies the partners use to address these. Two scenarios for system change to increase its effectiveness in achieving program goals are discussed.

Non-covalent and transient protein-ligand interactions are integral to cellular function and malfunction. Key steps in signalling and regulatory pathways rely on reversible non-covalent protein-protein binding or ion chelation. Here we present a microfluidic free-flow electrophoresis method for detecting and characterising protein-ligand interactions in solution. We apply this method to probe the binding equilibria of calmodulin, a central protein to calcium signalling pathways. In this study we characterise the specific binding of calmodulin to phosphorylase kinase, a known target, and creatine kinase, which we identify as a putative binding partner through a protein array screen and surface plasmon resonance experiments. We verify the interaction between calmodulin and creatine kinase in solution using free-flow electrophoresis and investigate the effect of calcium and sodium chloride on the calmodulin-ligand binding affinity in free solution without the presence of a potentially interfering surface. Our results demonstrate the general applicability of quantitative microfluidic electrophoresis to characterise binding equilibria between biomolecules in solution.

Although the number of employees on overseas assignments accompanied by their families has increased steadily, little is known about the effects of this experience on family functioning. Japanese families on family-accompanied assignments living in Hong Kong were compared with families living in Japan (consisting of 135 and 248 paired partners, respectively). Applying an ecological framework, family functioning was examined using the Feetham Family Functioning Survey-Japanese (FFFS-J). Japanese wives living in Hong Kong rated family functioning lower, particularly in the area of "relationship between family and family members." Between paired marital partners living in Hong Kong, the level of satisfaction in the area of "relationship between family and society" was significantly lower for wives than for husbands. This study provides application of the family ecological framework in families in a multicultural environment and identifies potential areas for family assessment and intervention that may of interest to health care professionals who care for families living away from their home countries.

We describe a Latino restaurateur's perspectives and partnership with Seattle-King County REACH to improve the healthfulness of his restaurant as a step toward tackling diabetes in his community. We interviewed the owner and reviewed other documentation to capture his perspectives and identify key elements in this restaurant intervention. The impact of diabetes in the owner's family and Latino community motivated him to make changes at his restaurant. If changes were successful, he hoped this would motivate other Latino restaurateurs to make similar changes. At his request, REACH gathered consumer feedback, provided diabetes education and nutritional guidance, and worked with him to develop simple, economically-feasible, healthier items. Positive consumer response and media coverage motivated the owner to explore additional changes at his restaurant and encourage other restaurateurs to make healthful changes. This intervention illustrates the potential for local businesses to collaborate with community partners, like REACH, to promote healthy food environments. PMID:22080779

An Agent-Based Epidemic Simulation of Social Behaviors Affecting HIV Transmission among Taiwanese Homosexuals

PubMed Central

2015-01-01

Computational simulations are currently used to identify epidemic dynamics, to test potential prevention and intervention strategies, and to study the effects of social behaviors on HIV transmission. The author describes an agent-based epidemic simulation model of a network of individuals who participate in high-risk sexual practices, using number of partners, condom usage, and relationship length to distinguish between high- and low-risk populations. Two new concepts—free links and fixed links—are used to indicate tendencies among individuals who either have large numbers of short-term partners or stay in long-term monogamous relationships. An attempt was made to reproduce epidemic curves of reported HIV cases among male homosexuals in Taiwan prior to using the agent-based model to determine the effects of various policies on epidemic dynamics. Results suggest that when suitable adjustments are made based on available social survey statistics, the model accurately simulates real-world behaviors on a large scale. PMID:25815047

The cytosol-facing membranes of cellular organelles contain proteins that enable signal transduction, regulation of morphology and trafficking, protein import and export, and other specialized processes. Discovery of these proteins by traditional biochemical fractionation can be plagued with contaminants and loss of key components. Using peroxidase-mediated proximity biotinylation, we captured and identified endogenous proteins on the outer mitochondrial membrane (OMM) and endoplasmic reticulum membrane (ERM) of living human fibroblasts. The proteomes of 137 and 634 proteins, respectively, are highly specific and highlight 94 potentially novel mitochondrial or ER proteins. Dataset intersection identified protein candidates potentially localized to mitochondria-ER contact sites. We found that one candidate, the tail-anchored, PDZ-domain-containing OMM protein SYNJ2BP, dramatically increases mitochondrial contacts with rough ER when overexpressed. Immunoprecipitation-mass spectrometry identified ribosome-binding protein 1 (RRBP1) as SYNJ2BP’s ERM binding partner. Our results highlight the power of proximity biotinylation to yield insights into the molecular composition and function of intracellular membranes.

Purpose Research on sexual-partner type focuses mostly on “main” and “casual” partner categories. The literature indicates that adolescent girls are less likely to use condoms with main partners, and more likely to use condoms with casual partners. Adolescent mothers may have different types of sexual partners than other adolescent girls. The purpose of this study was to explore and describe the range of male sexual partner types reported by Black adolescent mothers. Design and Sample This study was a qualitative description of the perspectives of Black, predominantly African-American, mothers (n=31). Data were generated using focus groups and interviews. The participants' ages ranged from 15–19 years. Measures A semi-structured qualitative questioning guide was used to stimulate focused discussions. Transcribed data were analyzed using qualitative content analysis. Results The range of sexual partner types of the women were reflected in three themes (1) All main partners are not created equal; (2) They're not casual partners because there are strings attached; (3) “Wham, bam, thank you ma'am:” No strings attached. Nine partner types were identified under these three themes, including a “baby daddy” partner. Conclusion The partner-types of Black adolescent mothers are more robust than the “main” and “casual” partner categories typically referenced in the research literature. The range of sex partners includes the birth fathers of their children. Clinicians and researchers must consider how co-parenthood status is used in the construction of the “baby daddy” partner and what implications this unique sexual partner type may have on risk reduction behaviors such as condom use.

Researchers have identified harm reduction strategies that gay, bisexual, and other men who have sex with men (GBMSM) use to reduce HIV transmission--including serosorting, status disclosure, and strategic positioning. We report on patterns of these behaviors among 376 highly sexually active (i.e., 9+partners, <90 days) GBMSM: mean age of 37, 49.5% men of color, 87.8% gay identified, 57.5% college educated. We found evidence that many men engaged in serosorting, status disclosure, and strategic positioning; however, rates varied based on the participant's HIV status. HIV-positive and HIV-negative men both engaged in sex with men of similar status more often than they engaged in sex with men known to be a different HIV status (i.e., serosorting). However, HIV-negative men disclosed their HIV-status with about half of their partners, whereas HIV-positive participants disclosed with only about one-third. With regard to strategic positioning, HIV-positive participants were the receptive partner about half the time with their HIV-negative partners and with their HIV-positive partners. In contrast, strategic positioning was very common among HIV-negative participants-they rarely bottomed with HIV-positive partners, bottomed about one-third of the time with status-unknown partners, and 42% of the time (on average) with HIV-negative partners. Highly sexually active GBMSM are a critical population in which to both investigate HIV prevention strategies as well as develop effective intervention programs. Providers and clinicians might be well served to include a wide range of behavioral harm reduction strategies in addition to condom use and biomedical approaches to reduce onward HIV transmission.

In this qualitative study, we explored women's pregnancy intentions and experiences of intimate partner violence before, during and after pregnancy. Unintended pregnancies in the context of intimate partner violence can have serious health, social and economic consequences for women and their children. Feminist and phenomenological philosophies underpinned the study to gain a richer understanding of women's experiences. Eleven women who had been pregnant in the previous two years were recruited from community-based women's refuges in one region of the UK. Of the 11 women, eight had unplanned pregnancies, two reported being coerced into early motherhood, and only one woman had purposively planned her pregnancy. Multiple in-depth interviews focused on participants' accounts of living with intimate partner violence. Experiential data analysis was used to identify, analyse and highlight themes. Three major themes were identified: men's control of contraception, partner's indiscriminate response to the pregnancy and women's mixed feelings about the pregnancy. Participants reported limited influence over their sexual relationship and birth control. Feelings of vulnerability about themselves and fear for their unborn babies' safety were intensified by their partners' continued violence during pregnancy. Women experiencing intimate partner violence were more likely to have an unintended pregnancy. This could be attributed to male dominance and fear, which impacts on a woman's ability to manage her birth control options. The women's initial excitement about their pregnancy diminished in the face of uncertainty and ongoing violence within their relationship. Women experiencing violence lack choice in relation to birth control options leading to unintended pregnancies. Interpreting the findings from the victim-perpetrator interactive spin theory of intimate partner violence provides a possible framework for midwives and nurses to better understand and respond to women's experiences of violence during pregnancy. © 2016 John Wiley & Sons Ltd.

Sources are four leading PR practitioners identified via bibliometric analysis. Authors' publications were identified in January 1995-October 2009 in PubMed, Embase, ISI Web of Science and CAB databases, and books. Works were limited to those with a process description describing a research project and practitioners were first, second, third, or last author. Adapting and applying the "Reliability Tested Guidelines for Assessing Participatory Research Projects" to retained records identified five key strategies: developing advisory committees of researchers and intended research users; developing research agreements; using formal and informal group facilitation techniques; hiring co-researchers/partners from community; and ensuring frequent communication. Other less frequently mentioned strategies were also identified. This review is the first time these guidelines were used to identify key strategies supporting PR projects. They proved effective at identifying and evaluating engagement strategies as reported by completed research projects. Adapting these guidelines identified gaps where the tool was unable to assess fundamental PR elements of power dynamics, equity of resources, and member turnover. Our resulting template serves as a new tool to measure partnerships.

Domestic violence against women committed by intimate partners is a worldwide concern especially in developing countries. The aim of this study was to assess the problem among Iranian women and identify associated risk factors. Using a cross-sectional multicenter design, 1,600 women in six different areas of Iran were surveyed. A measure of domestic violence against women was administered and demographic information collected. Logistic regression models were used to identify factors associated with domestic violence. The prevalence of domestic violence among participants were emotional (64%), physical (28%), and sexual (18%). Higher education (both women and their partners), employment status of partner (being employed), and lower number of children lowered the risk, whereas history of previous marriage (for either women or their partners), unstable marriage, substance abuse, crowded family situation, and lower socioeconomic status increased the risk of domestic violence. There is a high prevalence of domestic violence, particularly emotional, against women by their partners. Preventive measures are recommended such as increasing public awareness, improving in socioeconomic status of families, educating women about what they can do, and encouraging counseling for the couple or the woman alone.

ABSTRACT OBJECTIVE To estimate differential associations between the exposure to violence in the family of origin and victimization and perpetration of intimate partner violence in pregnancy. METHODS A nested case-control study was carried out within a cohort study with 1,120 pregnant women aged 18–49 years old, who were registered in the Family Health Strategy of the city of Recife, State of Pernambuco, Brazil, between 2005 and 2006. The cases were the 233 women who reported intimate partner violence in pregnancy and the controls were the 499 women who did not report it. Partner violence in pregnancy and previous experiences of violence committed by parents or other family members were assessed with a standardized questionnaire. Multivariate logistic regression analyses were modeled to identify differential associations between the exposure to violence in the family of origin and victimization and perpetration of intimate partner violence in pregnancy. RESULTS Having seen the mother suffer intimate partner violence was associated with physical violence in childhood (OR = 2.62; 95%CI 1.89–3.63) and in adolescence (OR = 1.47; 95%CI 1.01–2.13), sexual violence in childhood (OR = 3.28; 95%CI 1.68–6.38) and intimate partner violence during pregnancy (OR = 1.47; 95% CI 1.01 – 2.12). The intimate partner violence during pregnancy was frequent in women who reported more episodes of physical violence in childhood (OR = 2.08; 95%CI 1.43–3.02) and adolescence (OR = 1.63; 95%CI 1.07–2.47), who suffered sexual violence in childhood (OR = 3.92; 95%CI 1.86–8.27), and who perpetrated violence against the partner (OR = 8.67; 95%CI 4.57–16.45). CONCLUSIONS Experiences of violence committed by parents or other family members emerge as strong risk factors for intimate partner violence in pregnancy. Identifying and understanding protective and risk factors for the emergence of intimate partner violence in pregnancy and its maintenance may help policymakers and health service managers to develop intervention strategies.

Objective: A body of research has established that lower socioeconomic populations, including blue-collar workers, are at higher risk for problem drinking and intimate partner violence. This study of married/cohabiting construction workers and their spouses/partners describes how work stressors, hazardous drinking, and couple characteristics interact to influence normative beliefs around partner violence and, thereafter, its occurrence. Method: Our survey respondents from a sample of 502 dual-earner couples were asked about drinking patterns, past-year partner violence, normative beliefs about partner violence, work-related stressors, impulsivity, and childhood exposure to violence and other adverse events. We conducted semi-structured qualitative interviews with 81 workers on context of work stress, partner violence, and drinking. Results: Analyses of data revealed that men’s and women’s normative beliefs about partner violence were positively related to male-to-female partner violence; female partner violence normative beliefs were associated with female-to-male partner violence. Both partners’ levels of impulsivity were directly associated with male-to-female and female-to-male partner violence, and male partner’s frequency of intoxication mediated the association between level of impulsivity and male-to-female partner violence. Female partner’s adverse childhood experience was directly associated with male-to-female partner violence. Both survey and qualitative interviews identified individual and work-related factors that influence the occurrence of violence between men and women. Discussion: These findings provide guidelines for prevention of partner violence that can be implemented in the workplace with attention to hazardous drinking, job stress, treatment, education, and work culture.

Many native proteins are multi-specific and interact with numerous partners, which can confound analysis of their functions. Protein design provides a potential route to generating synthetic variants of native proteins with more selective binding profiles. Re-designed proteins could be used as research tools, diagnostics or therapeutics. In this work, we used a library screening approach to re-engineer the multi-specific anti-apoptotic protein Bcl-xL to remove its interactions with many of its binding partners, making it a high affinity and selective binder of the BH3 region of pro-apoptotic protein Bad. To overcome the enormity of the potential Bcl-xL sequence space, we developed and applied a computational/experimental framework that used protein structure information to generate focused combinatorial libraries. Sequence features were identified using structure-based modeling, and an optimization algorithm based on integer programming was used to select degenerate codons that maximally covered these features. A constraint on library size was used to ensure thorough sampling. Using yeast surface display to screen a designed library of Bcl-xL variants, we successfully identified a protein with ~1,000-fold improvement in binding specificity for the BH3 region of Bad over the BH3 region of Bim. Although negative design was targeted only against the BH3 region of Bim, the best re-designed protein was globally specific against binding to 10 other peptides corresponding to native BH3 motifs. Our design framework demonstrates an efficient route to highly specific protein binders and may readily be adapted for application to other design problems. PMID:23154169

Detailed information on the sexual behavior of bisexual, non-gay-identified men and the relationship between same-sex behavior and HIV/sexually transmitted infection (STI) incidence is limited. This study provides information on the sexual behavior with male partners of non-gay-identified men in urban, coastal Peru and the relationship of this behavior with HIV/STI incidence. We analyzed data from 2146 non-gay-identified men with a baseline and then 2 years of annual follow-up, including detailed information on sexual behavior with up to 5 sex partners, to determine the characteristics associated with bisexual behavior. Discrete time proportional hazards models were used to determine the effect of self-reported sex with men on subsequent HIV/STI incidence. Over the 3 study visits, sex with a man was reported by 18.9% of men, 90% of whom also reported sex with a female partner. At baseline, reported bisexual behavior was associated with other sexual risk behaviors such as exchanging sex for money and increased risk of HIV, herpes simplex virus type 2, and gonorrhea. The number of study visits in which recent sex with men was reported was positively correlated with risk of other sexual risk behaviors and incident HIV, herpes simplex virus type 2, and gonorrhea. Recent sex with a man was associated with increased HIV/STI incidence (hazard ratio, 1.79; confidence interval, 1.19-2.70), after adjusting for sociodemographics and other sexual risk behaviors. Given the prevalence of recent sex with men and the relationship of this behavior with HIV/STI incidence, interventions with non-gay-identified men who have sex with men and their partners are warranted.

The increasing number of potential drug target candidates has driven the development of novel technologies designed to identify functionally important targets and enhance the subsequent lead discovery process. Highly specific synthetic nucleic acid ligands--also known as aptamers--offer a new exciting route in the drug discovery process by linking target validation directly with HTS. Recently, aptamers have proven to be valuable tools for modulating the function of endogenous cellular proteins in their natural environment. A set of technologies has been developed to use these sophisticated ligands for the validation of potential drug targets in disease models. Moreover, aptamers that are specific antagonists of protein function can act as substitute interaction partners in HTS assays to facilitate the identification of small-molecule lead compounds.

Recent research has shown the Köhler motivation gain effect (working at a task with a more capable partner where one's performance is indispensable to the group) leads to greater effort in partnered exercise videogame play. The purpose of this article was to examine potential moderators of the Köhler effect by exploring dissimilarities in one's partner's appearance, namely, having an older partner (compared with a same-age partner) and having a heavier-weight partner (compared with a same-weight partner). One hundred fifty-three male and female college students completed a series of plank exercises using the "EyeToy: Kinetic™" for the PlayStation(®) 2 (Sony, Tokyo, Japan). Participants first completed the exercises individually and, after a rest, completed the same exercises with a virtually present partner. Exercise persistence, subjective effort, self-efficacy beliefs, enjoyment, and intentions to exercise were recorded and analyzed. A significant Köhler motivation gain was observed in all partner conditions (compared with individual controls) such that participants with a partner held the plank exercises longer (P<0.001) and reported higher subjective effort (P<0.01). These results were unmoderated by partner's age and weight, with one exception: Males tended to persist longer when paired with an obese partner (P=0.08). These results suggest that differences in age and weight do not attenuate the Köhler effect in exergames and may even strengthen it.

Trust contributes to young people's capacity for sustaining current and future successful relationships. To date, research has yet to examine the meaning of trust in early dating relationships and reasons for its deterioration. The present study focused on video-recorded conversations about trust between 34 heterosexual adolescent couples in dating relationships living in the U.S. Transcripts from these conversations were qualitatively analyzed using thematic analysis to identify adolescents' meanings of trust and reasons they provided for a lack of trust in their romantic partners. All 34 couples identified concerns specifically related to infidelity. Six major themes for not trusting romantic partners emerged. Results suggested that the lack of trust in romantic relationships might stem from several areas that are directly and indirectly related to the current relationship, including low self-esteem, the experience of betrayal in past romantic relationships, partners' extradyadic behaviors, and gossip among peers. Importantly, peers can play a defining role in influencing young people's perceptions of their romantic partners and developing or sustaining trust in their romantic relationships.

Objective: to identify the relationship between posttraumatic stress disorder, trait and state anxiety, and intimate partner violence during pregnancy. Method: observational, cross-sectional study developed with 358 pregnant women. The Posttraumatic Stress Disorder Checklist - Civilian Version was used, as well as the State-Trait Anxiety Inventory and an adapted version of the instrument used in the World Health Organization Multi-country Study on Women's Health and Domestic Violence. Results: after adjusting to the multiple logistic regression model, intimate partner violence, occurred during pregnancy, was associated with the indication of posttraumatic stress disorder. The adjusted multiple linear regression models showed that the victims of violence, in the current pregnancy, had higher symptom scores of trait and state anxiety than non-victims. Conclusion: recognizing the intimate partner violence as a clinically relevant and identifiable risk factor for the occurrence of anxiety disorders during pregnancy can be a first step in the prevention thereof.

Undiagnosed HIV infection is common among men who have sex with men (MSM) and transgender women (TW) in Latin America. We examined uptake of a partner notification (PN) model among MSM and TW in Tijuana, Mexico. Forty-six HIV-positive MSM/TW enrolled as index patients, and reported 132 MSM/TW sexual partners for PN. Of notified partners (90/132), 39% declined eligibility screening or participation, 39% tested for HIV, and of those 28% were newly-diagnosed HIV-positive. Partners who were seen by the index patient more than once in the past 4 months and those who primarily had sex with the index patient in one of their homes were more likely to be notified via PN (76% vs. 50%; p = 0.01 and 86% vs. 64%, p = 0.02, respectively). Lower than expected PN uptake was associated with problems identifying index patients, obtaining reliable partner contact information, and engaging notified partners.

Disclosure of HIV seropositive results among HIV-discordant couples in sub-Saharan Africa is generally low. We describe a facilitated couple counselling approach to enhance disclosure among HIV-discordant couples. Using unique identifiers, 293 HIV-discordant couples were identified through retrospective linkage of married or cohabiting consenting adults individually enrolled into a cohort study and into two randomized trials of male circumcision in Rakai, Uganda. HIV discordant couples and a random sample of HIV-infected concordant and HIV-negative concordant couples (to mask HIV status) were invited to sensitization meetings to discuss the benefits of disclosure and couple counselling. HIV-infected partners were subsequently contacted to encourage HIV disclosure to their HIV uninfected partners. If the index positive partner agreed, the counsellor facilitated the disclosure of HIV results, and provided ongoing support. The proportion of disclosure was determined. 81% of HIV-positive partners in discordant relationships disclosed their status to their HIV-uninfected partners in the presence of the counsellor. The rates of disclosure were 81.3% in male HIV-positive and 80.2% in female HIV-positive discordant couples. Disclosure did not vary by age, education or occupation. In summary, disclosure of HIV-positive results in discordant couples using facilitated couple counselling approach is high, but requires a stepwise process of sensitization and agreement by the infected partner.

An important goal of the Global Precipitation Measurement (GPM) mission is to maximize participation by non-NASA partners both domestic and international. A consequence of this objective is the provision for NASA to provide sufficient incentives to achieve partner buy-in and commitment to the program. NASA has identified seven specific areas in which substantive incentives will be offered: (1) partners will be offered participation in governance of GPM mission science affairs including definition of data products; (2) partners will be offered use of NASA's TDRSS capability for uplink and downlink of commands and data in regards to partner provided spacecraft; (3) partners will be offered launch support for placing partner provided spacecraft in orbit conditional upon mutually agreeable co-manifest arrangements; (4) partners will be offered direct data access at the NASA-GPM server level rather than through standard data distribution channels; (5) partners will be offered the opportunity to serve as regional data archive and distribution centers for standard GPM data products; and (6) partners will be offered the option to insert their own specialized filtering and extraction software into the GPM data processing stream or to obtain specialized subsets and products over specific areas of interest (7) partners will be offered GPM developed software tools that can be run on their platforms. Each of these incentives, either individually or in combination, represents a significant advantage to partners who may wish to participate in the GPM mission.

Partner-specific sexual practices among heterosexual men and women with multiple partners: results from the French national survey, ACSF. Analyse des Comportements Sexuel en France.

1996-06-01

Heterosexual men and women with several partners are at risk of acquiring and transmitting sexually transmitted diseases and HIV. Risk depends on parameters such as the sexual practices themselves which may vary according to the type of partner (regular vs. casual). It is therefore important to describe the sexual practices and identify the correlations between the type of partner and these practices among heterosexuals with multiple partners. A subsample of all subjects having had at least two sexual partners during the previous year (n = 1644) was obtained from the ACSF survey (n = 20,055), the French national telephone survey on sexual behavior conducted between September 1991 and February 1992. Questions concerned in particular sexual practices of the last encounter as well as type of partner. Petting and vaginal penetration were almost systematic, mutual manual stimulation and orogenital sex were common, while self-masturbation and anal sex were infrequent. On average, a condom was seldom used. However, it was used more often when the partner was occasional. Nonpenetrative and oral practices were also more frequent with occasional partners. Women tended to report lower frequencies of practices and of condom use than men. A subset of heterosexuals with multiple partners engaged in safe sex. Practices tend to be partner-specific, with safer sex practices more likely to occur with occasional partners, although the magnitude of the difference is moderate.

Balancing Competing Needs: A Meta-Ethnography of Being a Partner to an Individual With a Mood Disorder.

More than 20% of individuals experience a mood disorder in their lifetime. Qualitative studies have explored the experience of being a partner to an individual with a mood disorder, but these studies remain isolated pieces of a larger puzzle. In this metasynthesis, I aimed to integrate current qualitative research to describe the experience of being a partner to an individual with a mood disorder. A systematic search was conducted to identify qualitative research. Noblit and Hare's meta-ethnography was used to translate key metaphors from individual studies into a single set of metaphors to describe the experience. Results indicated that these partners are disenfranchised caregivers balancing their own needs with partners' perceived and reported needs to strive for a stasis of guarded stability. Future research must explore ways to support these partners and include them in the health care team. © The Author(s) 2015.

Verbal compliments as a differential source of mate poaching threat for men and women.

PubMed

Brown, Christina M; Daniels, Emily R; Lustgraaf, Christopher J N; Sacco, Donald F

2014-08-18

Two studies tested whether people feel threatened by another individual verbally complimenting their romantic partner. Such compliments may indicate that the other person is a potential rival who will try to "poach" their mate. Across two studies, women were more threatened than men when imagining another person complimenting their partner's physical appearance. There were no sex differences in response to imagining another person complimenting their partner's sense of humor. When another person compliments one's partner's physical appearance, this indicates that they may be sexually attracted to the partner. Mediation analyses revealed that the sex difference occurs because women believe men are more open to casual sex, and therefore more vulnerable to mate poaching when another person expresses sexual interest in them.

Intimate Partner Jealousy and Femicide Among Former Ethiopians in Israel.

Edelstein, Arnon

2018-02-01

Ethiopian immigrant women in Israel are overrepresented as victims of femicide; they are killed at more than 16 times the rate of the general population. This article suggests integrating current theoretical and empirical models to explain Ethiopian femicide, and stresses that considering psychological or sociocultural explanations as risk factors alone is not enough to understand this phenomenon. We distinguish between risk factors and triggers for femicide against Ethiopian women. While sociocultural and even psychological changes are risk factors for femicide, one, two, or three main triggers may activate such potential risk factors, such as the woman's willingness (WW) to leave the intimate relationship, sexual jealousy (SJ), and formal complaints against the abusive partner. The first two triggers are jealousy oriented. To analyze this phenomenon in Israel, we examined all court decisions on intimate partner homicide (IPH) from 1990 to 2010. After reading former studies on IPH and identifying important variables that could explain the phenomenon, we first catalogued the data in every decision and verdict according to main independent variables mentioned in the literature. The study population consists of first-generation immigrants, N = 194: native Israelis (47%), new immigrants from the former Soviet Union (FSU; 31%), and Ethiopians (16%). Our analysis of court decisions reveals that triggers containing jealousy components are responsible for 83% of femicide cases committed by Ethiopian men, in comparison with native Israelis (77%) and immigrant Russian men (66%) who murdered their intimate partners. In addition, there is a significant correlation among motive (jealousy), method of killing (stabbing), and "overkilling" (excessive force).

The Midwestern United States (U.S.) has a high number of recent Latino migrants, but little information is available regarding their sexual behaviors. A total of 75 behaviorally bisexual men (25 Latino, 25 Black, and 25 White) participated in an exploratory study on sexual health. The data presented in this paper are restricted to the 25 self-identified Latino men. Qualitative in-depth interviews were conducted and optional self-administered sexual transmitted infection (STI) screening was provided. The measures used were taken from the National Survey of Sexual Health and Behavior (NSSHB), a probability study of the sexual behaviors of nearly 6000 individuals aged 14-94 in the U.S. In our sample of bisexual men, the most commonly reported sexual behaviors were masturbation, vaginal intercourse, and receiving oral sex from male and female partners. The majority of the participants were the insertive partner during anal sex with male partners. Many of the participants reported alcohol use during their most recent sexual activity. A fair number reported not using condoms during their last sexual event. Pleasure, arousal, orgasm, and erectile functioning were markedly similar despite partner gender. A small number of participants also engaged in sexual activities with transgender individuals. All of the Latino participants took part in the optional self-collection for STI specimens. The results of the study provide rich insights into the sexual behavior and related factors, as well as potential risk behaviors of bisexual Latino men that may be targeted for future sexual health promotion efforts.

Engaging basic scientists in community-based translational research is challenging but has great potential for improving health. In 2009, The Rockefeller University Center for Clinical and Translational Science partnered with Clinical Directors Network, a practice-based research network (PBRN), to create a community-engaged research navigation (CEnR-Nav) program to foster research pairing basic science and community-driven scientific aims. The program is led by an academic navigator and a PBRN navigator. Through meetings and joint activities, the program facilitates basic science-community partnerships and the development and conduct of joint research protocols. From 2009-2014, 39 investigators pursued 44 preliminary projects through the CEnR-Nav program; 25 of those became 23 approved protocols and 2 substudies. They involved clinical scholar trainees, early-career physician-scientists, faculty, students, postdoctoral fellows, and others. Nineteen (of 25; 76%) identified community partners, of which 9 (47%) named them as coinvestigators. Nine (of 25; 36%) included T3-T4 translational aims. Seven (of 25; 28%) secured external funding, 11 (of 25; 44%) disseminated results through presentations or publications, and 5 (71%) of 7 projects publishing results included a community partner as a coauthor. Of projects with long-term navigator participation, 9 (of 19; 47%) incorporated T3-T4 aims and 7 (of 19; 37%) secured external funding. The CEnR-Nav program provides a model for successfully engaging basic scientists with communities to advance and accelerate translational science. This model's durability and generalizability have not been determined, but it achieves valuable short-term goals and facilitates scientifically meaningful community-academic partnerships.

Simulation-based mentalizing generates a "proxy" self-reference effect in memory.

PubMed

Allan, Kevin; Morson, Suzannah; Dixon, Susan; Martin, Douglas; Cunningham, Sheila J

2017-06-01

The self-reference effect (SRE) in memory is thought to depend on specialized mechanisms that enhance memory for self-relevant information. We investigated whether these mechanisms can be engaged "by proxy" when we simulate other people, by asking participants to interact with two virtual partners: one similar and one dissimilar to self. Participants viewed pairs of objects and picked one for themselves, for their similar partner, or their dissimilar partner. A surprise memory test followed that required participants to identify which object of each pair was chosen, and for whom. Finally, participants were shown both partners' object pairs again, and asked to indicate their personal preference. Four key findings were observed. Overlap between participants' own choice and those made for their partner was significantly higher for the similar than the dissimilar partner, revealing participants' use of their own preferences to simulate the similar partner. Recollection of chosen objects was significantly higher for self than for both partners and, critically, was significantly higher for similar than dissimilar partners. Source confusion between self and the similar partner was also higher. These findings suggest that self-reference by proxy enhances memory for non-self-relevant material, and we consider the theoretical implications for functional interpretation of the SRE.

Risk Perception, Sexual Behaviors, and PrEP Adherence Among Substance-Using Men Who Have Sex with Men: a Qualitative Study.

The antiretroviral drug combination emtricitabine and tenofovir disoproxil fumarate (TDF/FTC) taken as pre-exposure prophylaxis (PrEP) is effective in preventing HIV infection, yet it also requires adherence and potentially decreases condom use. This study sought to examine these issues among a key population at risk of HIV infection, substance-using men who have sex with men (MSM). We conducted semi-structured interviews with an ethnically diverse sample of 30 young (aged 20-35) MSM prescribed PrEP within a large integrated healthcare system in San Francisco, who had reported recent drug use or hazardous drinking and one or more missed doses of PrEP. We explored participants' risk perception and sexual risk behavior, drug and alcohol use, and PrEP adherence in the context of substance use. Interviews were transcribed and coded using a directed content analysis approach to identify key categories and commonalities, and differences across participants. Salient subcategories included positive psychological effects of being on PrEP (e.g., decreased anxiety, feelings of empowerment), social effects (e.g., reduced HIV stigma), and reduction in overall perceptions of HIV risk. While overall reported use of condoms went down and many reported a brief period of increased condomless sex following PrEP initiation, others continued condom use with most of their sexual partners. Contextual factors influencing their decision to engage in condomless sex included how well they knew the partner and whether the partner was on PrEP or HIV antiretroviral treatment. Factors associated with poor adherence included disruptions in daily routine and use of alcohol and methamphetamine. PrEP-prescribing clinicians should support their patients in making informed decisions about condom use and identifying strategies to maximize adherence in the context of substance use.

The human pituitary tumor-transforming gene is an oncogenic protein which serves as a central hub in the cellular signaling network of medulloblastoma. The protein contains two vicinal PxxP motifs at its C terminus that are potential binding sites of peptide-recognition SH3 domains. Here, a synthetic protocol that integrated in silico analysis and in vitro assay was described to identify the SH3-binding partners of pituitary tumor-transforming gene in the gene expression profile of medulloblastoma. In the procedure, a variety of structurally diverse, non-redundant SH3 domains with high gene expression in medulloblastoma were compiled, and their three-dimensional structures were either manually retrieved from the protein data bank database or computationally modeled through bioinformatics technique. The binding capability of these domains towards the two PxxP-containing peptides m1p: 161 LGPPSPVK 168 and m2p: 168 KMPSPPWE 175 of pituitary tumor-transforming gene were ranked by structure-based scoring and fluorescence-based assay. Consequently, a number of SH3 domains, including MAP3K and PI3K, were found to have moderate or high affinity for m1p and/or m2p. Interestingly, the two overlapping peptides exhibits a distinct binding profile to these identified domain partners, suggesting that the binding selectivity of m1p and m2p is optimized across the medulloblastoma expression spectrum by competing for domain candidates. In addition, two redesigned versions of m1p peptide ware obtained via a structure-based rational mutation approach, which exhibited an increased affinity for the domain as compared to native peptide.

Using benchmarking to minimize common DOE waste streams: Volume 5. Office paper waste

DOE Office of Scientific and Technical Information (OSTI.GOV)

Levin, V.

Finding innovative ways to reduce waste streams generated at US Department of Energy (DOE) sites by 50% by the year 2000 is a challenge for DOE`s waste minimization efforts. A team composed of members from several DOE facilities used the quality tool known as benchmarking to improve waste minimization efforts. First the team examined office waste generation and handling processes at their sites. Then team members developed telephone and written questionnaires to help identify potential ``best-in-class`` industry partners willing to share information about their best waste minimization techniques and technologies. The team identified two benchmarking partners, NIKE, Inc., in Beaverton,more » Oregon, and Microsoft, Inc., in Redmond, Washington. Both companies have proactive, employee-driven environmental issues programs. Both companies report strong employee involvement, management commitment, and readily available markets for recyclable materials such as white paper and nonwhite assorted paper. The availability of markets, the initiative and cooperation of employees, and management support are the main enablers for their programs. At both companies, recycling and waste reduction programs often cut across traditional corporate divisions such as procurement, janitorial services, environmental compliance, grounds maintenance, cafeteria operations, surplus sales, and shipping and receiving. These companies exhibited good cooperation between these functions to design and implement recycling and waste reduction programs.« less

Sexual partnerships and considerations for HIV antiretroviral pre-exposure prophylaxis utilization among high-risk substance using men who have sex with men.

Men who have sex with men (MSM) remain at great risk of HIV in the United States, representing 65 % of incident HIV infections. One factor contributing to the high rate of HIV infection among MSM is use of "recreational" drugs that are highly associated with unprotected anal sex. Pre-exposure chemoprophylaxis (PrEP) is a novel biomedical HIV prevention strategy that has the potential to reduce HIV transmission in MSM. Main and casual sex partners play a role in HIV prevention efforts for MSM. The study aimed to qualitatively explore the perceived influences of sexual relationships on promoting and inhibiting PrEP use among high-risk MSM who report regular drug use. Semi-structured qualitative interviews were conducted with 40 participants recruited in Boston, Massachusetts. Data were analyzed using descriptive qualitative analysis. Casual partners presented a distinct set of concerns from primary partnerships. MSM generally viewed main partners as a potential source of support for taking PrEP. Given their informal and often temporary nature, PrEP disclosure to casual partners was considered unnecessary. HIV-related stigma and substance use were also perceived as barriers to discussing PrEP use with casual partners. MSM articulated a high degree of personal agency regarding their ability to take PrEP. Findings suggest that behavioral interventions to improve PrEP utilization and adherence for high-risk MSM should be tailored to sex partner type and the parameters established between sex partners. Approaches to PrEP disclosure and partner engagement should be informed by the relative benefits and limitations characterized by these different types of relationships.

Epithelioid fibrous histiocytoma: molecular characterization of ALK fusion partners in 23 cases.

Epithelioid fibrous histiocytoma is a rare and distinctive cutaneous neoplasm. Most cases harbor ALK rearrangement and show ALK overexpression, which distinguish this neoplasm from conventional cutaneous fibrous histiocytoma and variants. SQSTM1 and VCL have previously been shown to partner with ALK in one case each of epithelioid fibrous histiocytoma. The purpose of this study was to examine a large cohort of epithelioid fibrous histiocytomas by next-generation sequencing to characterize the nature and prevalence of ALK fusion partners. A retrospective archival review was performed to identify cases of epithelioid fibrous histiocytoma (2012-2016). Immunohistochemistry was performed to confirm ALK expression. Targeted next-generation sequencing was applied on RNA extracted from formalin-fixed paraffin-embedded tissue to identify the fusion partners. Twenty-three cases fulfilled inclusion criteria. The mean patient age was 39 years (range, 8-74), there was no sex predilection, and >75% of cases involved the lower extremities. The most common gene fusions were SQSTM1-ALK (N=12; 52%) and VCL-ALK (N=7; 30%); the other four cases harbored novel fusion partners (DCTN1, ETV6, PPFIBP1, and SPECC1L). The pattern of ALK immunoreactivity was usually granular cytoplasmic (N=12; 52%) or granular cytoplasmic and nuclear (N=10; 43%); the case containing an ETV6 fusion partner showed nuclear staining alone. There was no apparent relationship between tumor morphology and the ALK fusion partner. In summary, SQSTM1 and VCL are the most common ALK fusion partners in epithelioid fibrous histiocytoma; DCTN1, ETV6, PPFIBP1, and SPECC1L represent rare fusion partners. The proteins encoded by these genes play diverse roles in scaffolding, cell adhesion, signaling, and transcription (among others) without clear commonalities. These findings expand the oncogenic promiscuity of many of these ALK fusion genes, which drive neoplasia in tumors of diverse lineages with widely varied clinical behavior. This is the first documented account of ETV6-ALK and SPECC1L-ALK translocations in neoplasms.

To describe the intimate partner violence suffered by youth and to identify the descriptions that best classify it according to gender. A cross-sectional study was carried out among a sample of 3,087 adult Spanish students. The CUVINO questionnaire was used, which measures 8 forms of intimate partner violence and uses 3 descriptions to classify it (abuse, fear and entrapment). Logistic regressions were carried out to identify differences by gender and associations between the subtypes of intimate partner violence and descriptions of the violent experience. Nearly half of the sample (44.6%) had some situation of unperceived violence, mainly of "detachment" (30.0%) and "coercion" (25.1%). All subtypes of intimate partner violence were more frequently perpetrated by women. The largest difference by gender was found in "emotional punishment" (experienced by 20.9% of men vs. 7.6% of women) and "physical violence" (6.6% vs. 2.3%). A total of 28.7% felt trapped, 11.8% felt fear and 6.3% felt mistreated. Men more frequently described themselves as trapped, but less often as afraid or abused. The subtype of intimate partner violence most associated with the feeling of entrapment was coercion in both men (OR=3.8) and women (OR=5.7). Men and women face intimate partner violence while dating differently; resources are needed to address them specifically. The inclusion of routine questions about the sense of entrapment may contribute to the early detection of intimate partner violence. Subtle forms of violence, such as coercion, should be taken into account in awareness campaigns. Copyright © 2014 SESPAS. Published by Elsevier Espana. All rights reserved.

HIV transmission in rural areas of China is being fueled in part by migrant workers who acquire HIV outside of their hometowns. Recent surveillance statistics indicate that HIV prevalence among returning migrants has increased significantly. We conducted a community-based cross-sectional study to assess HIV-related knowledge, attitudes and behaviors among migrant returnees in Nantong, Jiangsu Province, one of the largest exporters of migrant laborers. A total of 1625 subjects were enrolled with a response rate of 89%. All participants were male and of the majority Han ethnicity. The mean age was 39.0 years (SD = 6.7; range: 18 to 63), and most had a stable partner (N = 1533, 94.3%). Most correctly identified the major modes of HIV transmission (68.9%-82.0%), but fewer were able to identify ways that HIV cannot be transmitted. Nearly one-third of participants held positive attitudes toward having multiple sex partners, and nearly half believed that sex work should be legalized. Multiple logistic regression analysis indicated that risky sexual behavior (defined as sex with a casual or commercial sex partner) was associated with no stable partner; working abroad; correct condom use; age <22 at first sex; higher coital frequency; and having a positive attitude towards multiple sex partners. We found high levels of reported sex with a casual or commercial sex partner and low levels of consistent condom use. HIV prevention interventions among migrant workers need to focus on younger migrants, migrants without stable partners, and migrants who travel abroad for work.

Identification of patients who are at high risk for human immunodeficiency virus (HIV) infection can lead to reduced frequencies of high-risk behaviors, provision of timely care for infected individuals, and decreased transmission of HIV. The HIV-associated outreach programs at the OASIS Clinic of the King-Harbor/Drew University complex (Los Angeles, CA) has 3 components: a traditional partner-notification (i.e., contact-tracing) component, a focused-intervention component through which clients are given incentives to bring in persons they feel are at high risk for HIV infection, and an outreach component targeting hard-to-reach populations. These interventions are highly effective in identifying individuals early during the course of their disease, when initiation of antiretroviral therapy is most effective. The partner-services program at the OASIS Clinic has been particularly useful in identifying partners of HIV-positive women, whereas the focused-intervention program is most useful for identifying gay men who are unaware of their positive HIV serostatus. Successful targeted outreach programs can identify many individuals who would not otherwise be aware of their HIV infection, but the programs also require more clinicians to manage these patients.

Young women in sub-Saharan Africa are disproportionately affected by HIV, making the development of women initiated and controlled methods of prevention, including microbicides, a priority. Adherence is pivotal to microbicide efficacy and partner related factors are known to impact adherence. An analysis of disclosure of gel use to sexual partners and adherence in CAPRISA 004 women was conducted to better understand this relationship. Partner disclosure was significantly associated with a modest 4.2 % increased adherence (71.0 vs. 66.8 %, p = 0.03). Most women rated the experience of disclosure as positive, despite 6.7 % of partners expressing a negative reaction. Participants who disclosed were more likely to reside with their regular partner (14.4 vs. 8.4 %; p = 0.01) and reported consistent condom use at baseline (32.9 vs. 20.9 %; p< 0.01). Partner disclosure needs to be better understood as a potential facilitator or barrier to microbicide adherence. PMID:24633715

Perceptions of relationship satisfaction and addictive behavior: Comparing pornography and marijuana use.

Pyle, Tara M; Bridges, Ana J

2012-12-01

Background and aims Research indicates that excessive pornography use can negatively impact romantic relationships. However, it is unclear whether these negative outcomes are different than negative outcomes produced by other compulsive or addictive behaviors, such as drug use. This study compared perceptions of relationship outcomes from either a romantic partner's excessive marijuana or pornography use. Furthermore, this study experimentally manipulated four factors potentially related to perceptions of relationship satisfaction and addictive behavior. Methods A total of 186 college-aged women read 16 scenarios describing heterosexual romantic relationships in which one partner used either pornography or marijuana. Each scenario varied on four variables: relationship commitment, secrecy of partner's behavior, frequency of partner's behavior, and context of partner's behavior. Results Results suggest that partner pornography and marijuana use are perceived to impact romantic relationships similarly and are influenced by similar factors, such as greater frequency, higher secrecy, and partner's availability for interaction. Conclusions Such findings are consistent with recommendations by professionals that compulsive pornography use be considered worthy of treatment intervention.

Research on familiar face recognition has largely focused on the neural correlates of recognizing a beloved partner or family member. However, no research has explored the effect of marriage style on the recognition of a beloved partner's face, especially in matriarchal societies. Here, we examined the time course of event-related potentials (ERP) in response to the face of a beloved partner, sibling, or unknown person in a sample of individuals from the matriarchal Mosuo tribe. Two groups were assessed: intermarriage and walking marriage groups (i.e., couples in a committed relationship who do not cohabitate during the daytime). In agreement with previous reports, ERP results revealed more positive VPP, N250, and P300 waveforms for beloved faces than sibling faces in both groups. Moreover, P300 was more positive for beloved partner versus sibling faces; however, this difference emerged at fronto-central sites for the walking marriage group and at posterior sites for the intermarriage group. Overall, we observed that marriage style affects the later stage processing of a beloved partner's face, and this may be associated with greater affective arousal and familiarity.

Patients, persons or partners? Involving those with chronic disease in their care.

PubMed

McWilliam, Carol L

2009-12-01

Self-care management is essential for effective chronic disease management. Yet prevailing approaches of healthcare practitioners often undermine the efforts of those who require on-going medical attention for chronic conditions, emphasizing their status as patients, failing to consider their larger life experience as people, and most importantly, failing to consider them as people with the potential to be partners in their care. This article explores two approaches for professional-patient interaction in chronic disease management, namely, patient-centred care and empowering partnering, illuminating how professionals might better interact with chronically ill individuals who seek their care. The opportunities, challenges, theory and research evidence associated with each approach are explored. The advantages of moving beyond patient-centred care to the empowering partnering approach are elaborated. For people with chronic disease, having the opportunity to engage in the social construction of their own health as a resource for everyday living, the opportunity to experience interdependence rather than dependence/independence throughout on-going healthcare, and the opportunity to optimize their potential for self-care management of chronic disease are important justifications for being involved in an empowering partnering approach to their chronic disease management.

In most primate societies, strong and enduring social bonds form preferentially among kin, who benefit from cooperation through direct and indirect fitness gains. Chimpanzees, Pan troglodytes , differ from most species by showing consistent female-biased dispersal and strict male philopatry. In most East African populations, females tend to forage alone in small core areas and were long thought to have weak social bonds of little biological significance. Recent work in some populations is challenging this view. However, challenges remain in quantifying the influence of shared space use on association patterns, and in identifying the drivers of partner preferences and social bonds. Here, we use the largest data set on wild chimpanzee behaviour currently available to assess potential determinants of female association patterns. We quantify pairwise similarities in ranging, dyadic association and grooming for 624 unique dyads over 38 years, including 17 adult female kin dyads. To search for social preferences that could not be explained by spatial overlap alone, we controlled for expected association based on pairwise kernel volume intersections of core areas. We found that association frequencies among females with above-average overlap correlated positively with grooming rates, suggesting that associations reflected social preferences in these dyads. Furthermore, when available, females preferred kin over nonkin partners for association and grooming, and variability was high among nonkin dyads. While variability in association above and below expected values was high, on average, nonkin associated more frequently if they had immature male offspring, while having female offspring had the opposite effect. Dominance rank, an important determinant of reproductive success at Gombe, influenced associations primarily for low-ranking females, who associated preferentially with each other. Our findings support the hypothesis that female chimpanzees form well-differentiated social relationships that are of potential adaptive value to females and their offspring.

Background Mutations in the chromodomain helicase DNA binding protein 7 gene (CHD7) lead to CHARGE syndrome, an autosomal dominant multiple malformation disorder. Proteins involved in chromatin remodeling typically act in multiprotein complexes. We previously demonstrated that a part of human CHD7 interacts with a part of human CHD8, another chromodomain helicase DNA binding protein presumably being involved in the pathogenesis of neurodevelopmental (NDD) and autism spectrum disorders (ASD). Because identification of novel CHD7 and CHD8 interacting partners will provide further insights into the pathogenesis of CHARGE syndrome and ASD/NDD, we searched for additional associated polypeptides using the method of stable isotope labeling by amino acids in cell culture (SILAC) in combination with mass spectrometry. Principle findings The hitherto uncharacterized FAM124B (Family with sequence similarity 124B) was identified as a potential interaction partner of both CHD7 and CHD8. We confirmed the result by co-immunoprecipitation studies and showed a direct binding to the CHD8 part by direct yeast two hybrid experiments. Furthermore, we characterized FAM124B as a mainly nuclear localized protein with a widespread expression in embryonic and adult mouse tissues. Conclusion Our results demonstrate that FAM124B is a potential interacting partner of a CHD7 and CHD8 containing complex. From the overlapping expression pattern between Chd7 and Fam124B at murine embryonic day E12.5 and the high expression of Fam124B in the developing mouse brain, we conclude that Fam124B is a novel protein possibly involved in the pathogenesis of CHARGE syndrome and neurodevelopmental disorders.

Health care providers in India are often the only institutional contact for women experiencing intimate partner violence (IPV), a pervasive public health problem with adverse health outcomes. This qualitative study was among the first to examine Indian primary care physicians’ IPV practices. Between July 2007 and January 2008, 30 in-depth interviews were conducted with physicians serving low-to-middle income women aged 18–30 in southern India. A modified grounded theory approach was used for data collection and analysis. Study findings revealed a distinct subset of ‘physician champions’ who responded to IPV more consistently, informed women of their rights, and facilitated their utilization of support services. Findings also offered insights into physicians’ ability to identify indications of IPV and use of potentially culturally appropriate practices to respond to IPV, even without training. However, physician practices were mediated by individual attitudes. Although not generalizable, findings offer some useful lessons which may be transferable for adaptation to other settings. A potential starting point is to study physicians’ current practices, focusing on their safety and efficacy, as well as enhancing these practices through appropriate training. Further research is also needed on women’s perspectives on the appropriateness of physicians’ practices, and women’s recommendations for IPV intervention strategies. PMID:21476176

Prior research on patterns of intimate partner violence (IPV) has documented changes over time, but few studies have focused directly on IPV desistance processes. This analysis identifies unique features of IPV, providing a rationale for the focus on this form of behavior cessation. We develop a life-course perspective on social learning as a conceptual framework and draw on qualitative interviews (n = 89) elicited from a sample of young adults who participated in a larger longitudinal study (Toledo Adolescent Relationships Study). The respondents' backgrounds reflected a range of persistence and desistance from IPV perpetration. Our analyses revealed that relationship-based motivations and changes were central features of the narratives of successful desisters, whether articulated as a stand-alone theme or in tandem with other potential “hooks” for change. The analysis provides a counterpoint to individualistic views of desistance processes, highlighting ways in which social experiences foster attitude shifts and associated behavioral changes that respondents tied to this type of behavior change. The analyses of persisters and those for whom change seemed to be a work in progress provide points of contrast and highlight barriers that limit a respondent's desistance potential. We describe implications for theories of desistance as well as for IPV prevention and intervention efforts. PMID:26538680

Aggression between partners represents a potential guiding force in family dynamics. However, research examining the influence of partner aggression (physically and psychologically aggressive acts by both partners) on harsh parenting and young child adjustment has been limited by a frequent focus on low-risk samples and by the examination of partner aggression at a single time point. Especially in the context of multiple risk factors and around transitions such as childbirth, partner aggression might be better understood as a dynamic process. In the present study, longitudinal trajectories of partner aggression from birth to age 3 years in a large, high-risk, and ethnically diverse sample (N = 461) were examined. Specific risk factors were tested as predictors of aggression over time, and the longitudinal effects of partner aggression on maternal harsh parenting and child maladjustment were examined. Partner aggression decreased over time, with higher maternal depression and lower maternal age predicting greater decreases in partner aggression. While taking into account contextual and psychosocial risk factors, higher partner aggression measured at birth and a smaller decrease over time independently predicted higher levels of maternal harsh parenting at age 3 years. Initial level of partner aggression and change over time predicted child maladjustment indirectly (via maternal harsh parenting). The implications of understanding change in partner aggression over time as a path to harsh parenting and young children's maladjustment in the context of multiple risk factors are discussed.

Shim, Woochan S; Nelson-Becker, Holly

2009-01-01

While literature on elder abuse has expanded, elder abuse by intimate partners has been less investigated. Even less is known about intimate partner violence among older Koreans living in North America. This article identifies important cultural considerations for individuals helping the Korean older adult community, beginning with the definition of intimate partner violence in this community and barriers to leaving that include traditional views of the East Asian self. Current practice interventions are discussed and recommendations for future practice such as healing han, the accumulated suffering from years of abuse, are suggested. The ultimate goal of this paper is to expand awareness in order to develop the best culturally competent prevention and intervention practice for Korean older intimate partner violence survivors in North America.

Public health partner notification (PN) services currently affect only a small minority of patients with gonorrhea or chlamydial infection and new approaches to PN are needed. To expand PN for gonorrhea and chlamydial infection to private sector patients and to assess the feasibility of treating sex partners through commercial pharmacies. Selected patients were offered PN assistance and were randomly offered medication to deliver to their partners. Providers permitted the health department to contact 3613 (91%) of 3972 potentially eligible patients, and 1693 (67%) of 2531 successfully contacted patients consented to interview. Of these, 1095 (65%) reported at least one untreated partner. Most patients (90%) wished to notify partners themselves. Patients were more likely to have partners who had not yet been treated and to request PN assistance if they had more than one sex partner in the preceding 60 days or a partner they did not anticipate having sex with in the future. These two factors characterized 49% of all patients interviewed, 70% of those with a partner that was untreated 7 or more days after index patient treatment, and 83% of those accepting PN assistance. Among 458 randomly selected patients with untreated partners at time of study interview, 346 (76%) agreed to deliver treatment to a partner. Of these, most (266) chose to obtain medication for a partner at a pharmacy, of whom 223 (84%) successfully did so. A substantial minority of private sector patients have untreated partners more than 7 days after their own treatment; some need help with PN, but most will agree to deliver medication to partners themselves.

From Sexual Assault to Sexual Risk: A Relational Pathway?

Among women and gay and bisexual men, sexual assault is associated with increased rates of sexual risk behavior and negative sexual health outcomes. Although the mechanisms of these effects are potentially myriad, the current analyses examine the role of perceived partner pressure for condomless sex in mediating the association between adult sexual assault (ASA) and recent anal or vaginal sex without a condom. In a sample of 205 young adult women and gay and bisexual men, ASA was indirectly associated with condomless anal and/or vaginal sex via perceptions of partner pressure for condomless sex, χ2(1) = 5.66, p = .02, after controlling for race, age, gender and sexual identity, and relationship status. The elucidation of this relational mechanism points to several potential intervention and prevention strategies that may reduce actual and perceived pressure for sex without a condom, including strategies designed to facilitate the prioritization of health and safety over relational goals and the improvement of partner selection and perceptions of partner pressure.

2016-01-01

Despite the well-documented relations between intimate partner violence and suicidal ideation, gender differences regarding the relationships between intimate partner violence types and suicidal ideation are less understood. In addition, few studies have examined the risk that harassment may confer for suicidal ideation in the context of intimate partner violence. This study examined gender differences in the associations of harassment, emotional, and physical intimate partner violence with suicidal ideation in 502 college students, while controlling for the influence of depressive symptoms. Results indicated that physical abuse, but not harassment or emotional abuse, was associated with increased suicidal ideation in men. In contrast, emotional abuse, but not physical abuse or harassment, was associated with increased suicidal ideation in women. Clinicians should consider potential gender differences in the impact of intimate partner violence on suicidal ideation when assessing suicide risk.

Social networking smartphone applications and sexual health outcomes among men who have sex with men.

Several smartphone applications (apps) designed to help men who have sex with men (MSM) find casual sexual partners have appeared on the market recently. Apps of this nature have the potential to impact sexual health and behavior by providing constant access to a large supply of available partners. In this study, the sexual health history, behavior, and personality of MSM who use these apps was compared to MSM who meet partners in other ways. A sample of 110 adult MSM was recruited online to complete a cross-sectional survey. All participants were either single or involved in a non-exclusive romantic relationship. There were no statistically significant differences between app users and non-users in frequency of insertive or receptive anal sex without a condom. However, app users reported significantly more sexual partners and had a higher prevalence of ever being diagnosed with an STI than did non-users. App users did not differ from non-users on any demographic or personality variables (including erotophilia, sensation seeking, and self-control); however, when adjusting lifetime total sex partners for those met specifically through apps, app users still had significantly more partners. This pattern of results suggests that app users may be more sexually active in general. More work is needed to fully understand the association between this emerging technology and potential sexual health risks.

Empathy, Pain and Attention: Cues that Predict Pain Stimulation to the Partner and the Self Capture Visual Attention

Empathy motivates helping and cooperative behaviors and plays an important role in social interactions and personal communication. The present research examined the hypothesis that a state of empathy guides attention towards stimuli significant to others in a similar way as to stimuli relevant to the self. Sixteen couples in romantic partnerships were examined in a pain-related empathy paradigm including an anticipation phase and a stimulation phase. Abstract visual symbols (i.e., arrows and flashes) signaled the delivery of a Pain or Nopain stimulus to the partner or the self while dense sensor event-related potentials (ERPs) were simultaneously recorded from both persons. During the anticipation phase, stimuli predicting Pain compared to Nopain stimuli to the partner elicited a larger early posterior negativity (EPN) and late positive potential (LPP), which were similar in topography and latency to the EPN and LPP modulations elicited by stimuli signaling pain for the self. Noteworthy, using abstract cue symbols to cue Pain and Nopain stimuli suggests that these effects are not driven by perceptual features. The findings demonstrate that symbolic stimuli relevant for the partner capture attention, which implies a state of empathy to the pain of the partner. From a broader perspective, states of empathy appear to regulate attention processing according to the perceived needs and goals of the partner. PMID:28979199

Partner preferences among survivors of betrayal trauma.

PubMed

Gobin, Robyn L

2012-01-01

Betrayal trauma theory suggests that social and cognitive development may be affected by early trauma such that individuals develop survival strategies, particularly dissociation and lack of betrayal awareness, that may place them at risk for further victimization. Several experiences of victimization in the context of relationships predicated on trust and dependence may contribute to the development of relational schema whereby abuse is perceived as normal. The current exploratory study investigates interpersonal trauma as an early experience that might impact the traits that are desired in potential romantic partners. Participants in the current study were asked to rate the desirability of several characteristics in potential romantic partners. Although loyalty was desirable to most participants regardless of their trauma history, those who reported experiences of high betrayal trauma rated loyalty less desirable than those who reported experiences of traumas that were low and medium in betrayal. Participants who reported experiences of revictimization (defined as the experience of trauma perpetrated by a close other during 2 different developmental periods) differed from participants who only reported 1 experience of high betrayal trauma in their self-reported desire for a romantic partner who possessed the traits of sincerity and trustworthiness. Preference for a partner who uses the tactic of verbal aggression was also associated with revictimization status. These preliminary findings suggest that victimization perpetrated by close others may affect partner preferences.

Ports and pests: Assessing the threat of aquatic invasive species introduced by maritime shipping activity in Cuba.

Aquatic invasive species (AIS) are biological pollutants that cause detrimental ecological, economic, and human-health effects in their introduced communities. With increasing globalization through maritime trade, ports are vulnerable to AIS exposure via commercial vessels. The Cuban Port of Mariel is poised to become a competitive transshipment hub in the Caribbean and the intent of this study was to evaluate present and potential impacts AIS pose with the likely future increase in shipping activity. We utilized previous assessment frameworks and publicly accessible information to rank AIS by level of threat. Fifteen AIS were identified in Cuba and one, the Asian green mussel Perna viridis (Linnaeus, 1758), had repeated harmful economic impacts. Five species associated with trade partners of Port Mariel were considered potentially detrimental to Cuba if introduced through shipping routes. The results presented herein identify species of concern and emphasize the importance of prioritizing AIS prevention and management within Cuba. Copyright © 2017 Elsevier Ltd. All rights reserved.

“Manejar la Situacion”: Partner Notification, Partner Management, and Conceptual Frameworks for HIV/STI Control Among MSM in Peru

2015-01-01

Previous analyses of Partner Notification (PN) have addressed individual, interpersonal, social, and structural issues influencing PN outcomes but have paid less attention to the conceptual framework of PN itself. We conducted 18 individual interviews and 8 group discussions, in a two-stage qualitative research process, to explore the meanings and contexts of PN for sexually transmitted infections (STI) among men who have sex with men (MSM) and men who have sex with men and women (MSMW) in Lima, Peru. Participants described PN as the open disclosure of private, potentially stigmatizing information that could strengthen or disrupt a partnership, structured by the tension between concealment and revelation. In addition to informing partners of an STI diagnosis, the act of PN was believed to reveal other potentially stigmatizing information related to sexual identity and practices such as homosexuality, promiscuity, and HIV co-infection. In this context, the potential development of visible, biological STI symptoms represented a risk for disruption of the boundary between secrecy and disclosure that could result in involuntary disclosure of STI status. To address the conflict between concealment and disclosure, participants cited efforts to “manejar la situacion” [manage the situation] by controlling the biological risks of STI exposure without openly disclosing STI status. We use this concept of “managing the situation” as a practical and theoretical framework for comprehensive Partner Management for HIV/STI control systems among MSM in Latin America. PMID:25821149

2016-01-01

Background The prevalence of sexually transmitted infections (STIs) among female sex workers (FSWs) in sub-Saharan Africa remains high. Providing treatment to the affected FSWs is a challenge, and more so to their stable sexual partners. There is scanty research information on acceptance of STI treatment for stable sexual partners by FSWs. We conducted a study to assess acceptance of STI treatment for stable sexual partners by FSWs, and to identify factors associated with acceptance. Methods We enrolled 241 FSWs in a cross sectional study; they were aged ≥ 18 years, had a stable sexual partner and a diagnosis of STI. Factors associated with acceptance of STI treatment for stable sexual partners were analysed in STATA (12) using Poisson regression. Mantel-Haenszel tests for interaction were performed. Results Acceptance of partner treatment was 50.6%. Majority (83.8%) of partners at the last sexual act were stable partners, and 32.4% of participants had asymptomatic STIs. Factors independently associated with acceptance were: earning ≤ $4 USD per sexual act (aPR 0.68; 95% CI: 0.49–0.94) and a clinical STI diagnosis (aPR 1.95; 95% CI: 1.30–2.92). The effect of low income on acceptance of partner treatment was seen in those with less education. Conclusion Acceptance of STI treatment for stable sexual partners was lower than that seen in other studies. Interventions to improve economic empowerment among FSWs may increase acceptance of partner treatment. PMID:27171270

SPIB and BATF provide alternate determinants of IRF4 occupancy in diffuse large B-cell lymphoma linked to disease heterogeneity

Interferon regulatory factor 4 (IRF4) is central to the transcriptional network of activated B-cell-like diffuse large B-cell lymphoma (ABC-DLBCL), an aggressive lymphoma subgroup defined by gene expression profiling. Since cofactor association modifies transcriptional regulatory input by IRF4, we assessed genome occupancy by IRF4 and endogenous cofactors in ABC-DLBCL cell lines. IRF4 partners with SPIB, PU.1 and BATF genome-wide, but SPIB provides the dominant IRF4 partner in this context. Upon SPIB knockdown IRF4 occupancy is depleted and neither PU.1 nor BATF acutely compensates. Integration with ENCODE data from lymphoblastoid cell line GM12878, demonstrates that IRF4 adopts either SPIB- or BATF-centric genome-wide distributions in related states of post-germinal centre B-cell transformation. In primary DLBCL high-SPIB and low-BATF or the reciprocal low-SPIB and high-BATF mRNA expression links to differential gene expression profiles across nine data sets, identifying distinct associations with SPIB occupancy, signatures of B-cell differentiation stage and potential pathogenetic mechanisms. In a population-based patient cohort, SPIBhigh/BATFlow-ABC-DLBCL is enriched for mutation of MYD88, and SPIBhigh/BATFlow-ABC-DLBCL with MYD88-L265P mutation identifies a small subgroup of patients among this otherwise aggressive disease subgroup with distinct favourable outcome. We conclude that differential expression of IRF4 cofactors SPIB and BATF identifies biologically and clinically significant heterogeneity among ABC-DLBCL. PMID:24875472

Five-Year-Old Preschoolers' Sharing is Influenced by Anticipated Reciprocation.

Xiong, Mingrui; Shi, Jiannong; Wu, Zhen; Zhang, Zhen

2016-01-01

Whether children share in anticipation of future benefits returned by a partner is an interesting question. In this study, 5-year-old children and an adult partner played a sharing game, in which children donated first and the partner donated afterward. In Experiment 1, the partner's resources were more attractive than the child's. In the reciprocal condition, the child was told that s/he would be a recipient when the partner played as a donor. In the non-reciprocal condition, however, the child was told that an anonymous child would be the recipient when the partner donated. Results showed that children shared more with the partner when they knew that they would be a recipient later. In Experiment 2, the child was always the recipient when the partner donated, but the partner's resources were more desirable than the child's in the high-value condition, and less desirable in the low-value condition. We found that children were more generous when the partner's resources were valued higher. These findings demonstrate that 5-year-old preschoolers' sharing choices take into account the anticipated reciprocity of the recipient, suggesting either self-interested tactical sharing or direct reciprocity in advance of receiving. Specifically, they adjust their sharing behavior depending on whether a partner has the potential to reciprocate, and whether it is worth sharing relative to the value of the payback.

In 2015, the World Health Organization reported that more than 60 million people were tested for HIV in 122 low- and middle-income countries between 2010 and 2014. Despite this level of progress, over 40% of people living with HIV remain unaware of their HIV status. This calls for innovative approaches to improve uptake of HIV testing services, including use of HIV self-test (HIVST) kits. We conducted a cross-sectional, qualitative study to assess pregnant women and their male partners' perceptions regarding female partner-delivered HIVST kits. This study was conducted at two health facilities in Central Uganda between November and December 2015. Data were collected on pregnant women's willingness to take HIVST kits to their male partners and other household members using eight focus group discussions and 30 in-depth interviews. Data were analyzed following a thematic framework approach. Overall, pregnant women were willing to take HIVST kits to their partners and other household members, with the exception of their cowives. Male partners were willing to use HIVST kits brought by their female partners. Our findings suggest that secondary distribution of HIVST kits through female partners is acceptable and has the potential to improve male partner and household-member HIV testing.

Prostate cancer is the most common non-skin cancer in men and sexual dysfunction is the most frequently reported long-term side effect of prostate cancer surgery or radiation. The aim of this study was to examine the experiences of men with sexual dysfunction and their partners following prostate cancer treatment. Men with sexual dysfunction from either surgical removal or radiation therapy 1-5 years after treatment were interviewed, as well as their partners. A mixed method design was used to determine the lived experience of men with sexual dysfunction. Open-ended questions guided the interviews. Twenty seven men completed the study with a mean age of 61 years (SD = 8.0; range = 44-77 years). Nine partners also participated. The majority of men (92.6%) had surgery. The average time from treatment to the interview was 23.5 months (SD = 11.7). Themes were frustration with sexual dysfunction, importance of support and understanding from others, depression and anxiety related to sexual dysfunction, importance of intimacy with partner, factors that impact treatment satisfaction, and education and comprehensive information about sex. Prostate cancer survivors and partners need accurate information about sexual side effects before during and after treatment. Men and partners required individualized help and guidance to manage sexual dysfunction. Support and understanding from partners, family, and others was also identified as an important aspect of healing and adjustment after prostate cancer treatment. Prostate cancer education/support groups played a key role in helping men and partners gain advocacy, education, and support. Psychological problems such as depression and anxiety need to be identified and addressed in men after prostate cancer treatment. Men and partners need assistance in understanding and navigating their way through intimacy to move forward with connectedness in their relationship. Satisfaction with treatment and with providers is dependent on patient education and understanding of all aspects of prostate cancer treatment including sexual side effects and incontinence.

When community partners have direct interaction with human research participants, it is important to consider potential threats to participant protections and research integrity. Few studies have directly compared the views of academic and community partners. This pilot focus group study explores the views of academic partners (APs) and community partners (CPs) regarding challenges to the protection of research participants and research integrity in community-engaged research (CEnR). Data are analyzed to understand how APs and CPs define and think about ethical problems and how meaning and analysis may differ between the two groups. Findings have implications for the development of research ethics training materials for academic-community research partnerships and IRBs; best practices for CEnR; and future research on ethical issues in CEnR.

Intimate partner violence (IPV) often culminates in acute physical injury, sexual assault, and mental health issues. It is crucial to understand the healthcare habits of victims to develop interventions that can drastically improve a victim's quality of life and prevent future abuse. The objective of this study is to mine de-identified and aggregated Electronic Health Record data to identify women's health issues that are potentially associated with IPV. In this study we compared health issues of female domestic abuse victims to female non-domestic abuse victims. The Domestic abuse population contained 5870 patients, while the Non-Domestic Abuse population contained 14,315,140 patients. Explorys provides National Big Data from the entire USA. Statistical analysis identified 2429 terms as significantly more prevalent among victims of domestic abuse, compared to the general population. These terms were classified into broad categories, including acute injury, chronic conditions, substance abuse, mental health, disorders, gynecological and pregnancy related problems.

Although sexual activity can cause moderate stress, it can cause natural death in individuals with pre-existing illness. The aim of this study was to identify additional pre-existing health problems, sexual practices, and potential circumstances that may trigger fatal events. This medicolegal postmortem, retrospective, and prospective study is based on data of autopsies performed at the Institute of Legal Medicine of the University hospital, Goethe-University, Frankfurt/Main, Germany. Identification of pre-existing health problems, sexual practices, and potential circumstances than could trigger fatal events. From 1972 to 2016 (45 years) approximately 38,000 medicolegal autopsies were performed, of which 99 cases of natural death were connected to sexual activities (0.26%). Except for eight women, men represented most cases. The women's mean age was 45 years (median = 45) and the men's mean age was 57.2 years (median = 57). Causes of death were coronary heart disease (n = 28), myocardial infarction (n = 21) and reinfarction (n = 17), cerebral hemorrhage (n = 12), rupture of aortic aneurysms (n = 8), cardiomyopathy (n = 8), acute heart failure (n = 2), sudden cardiac arrest (n = 1), myocarditis (n = 1), and a combination of post myocardial infarction and cocaine intoxication (n = 1). Most cases showed increased heart weights and body mass indices. Death occurred mainly during the summer and spring and in the home of the deceased. If sexual partners were identified, 34 men died during or after sexual contact with a female prostitute, two cases at least two female prostitutes. Nine men died during or after sexual intercourse with their wife, in seven cases the sexual partner was a mistress, and in four cases the life partner. Five men died during homosexual contacts. Based on the situation 30 men were found in, death occurred during masturbation. Of the women, five died during intercourse with the life partner, two died during intercourse with a lover or friend, and in one case no information was provided. Natural deaths connected with sexual activity appear to be associated with male sex and pre-existing cardiovascular disorders. Most cases recorded occurred with mistresses, prostitutes, or during masturbation. If death occurs, the spouse or life partner might need psychological support. To our knowledge, the present study contains the largest collection of postmortem data on natural deaths connected with sexual activities. However, the cases presented were of forensic interest; a larger number of undetected cases especially in the marital or stable relationship sector must be assumed. Patients should be informed about the circumstances that could trigger the "love death." Lange L, Zedler B, Verhoff MA, Parzeller M.

This study aimed to: (1) examine the relationship between interpersonal as well as social-demographic, cultural and structural factors, and condom non-use by sex workers' main intimate or other non-paying male sex partners (NPPs), as reported by a sample of sex workers (SWs); and (2) understand HIV/sexually transmitted infections (STIs) risk (e.g., numbers of sexual partners; condom use with different partners) among couples comprised of a sub-set of SWs and their NPPs. Bivariate and multivariable logistic regression was used to identify factors associated with condom non-use at last sex by the main NPP, as reported by SWs. Adjusted odds ratios and 95% confidence intervals are reported (AOR[95%CIs]). Data were drawn from cross-sectional surveys in Bagalkot District, Karnataka State, South India. Responses by SWs whose main NPPs agreed to enrol in the study and the main NPP enroled were linked; these responses by couples (pairs of SWs and NPPs) were examined to assess sexual risk for HIV/STIs. Overall, this study included 257 SWs and 76 NPPs. The data from 67 couples (88.2%) could be linked. In over a quarter of partnerships, at least one (SW or NPP) partner reported having another type of partner besides each other (and clients of SWs). In multivariable analysis, significantly increased odds of condom non-use at last sex with the main NPP were found for the following key factors: planning to have a child with their main NPP (AOR = 3.71[1.44-9.58]); and having decisions about condom use made by their main NPP (AOR = 9.87[4.03-24.16]) or both equally (AOR = 3.18[1.39-7.80]) (versus by the SWs herself). Our study highlights the potential risk for HIV/STI acquisition and transmission between NPPs and SWs, and between NPPs and their non-SWs wives and other sex partners. Study results underscore the need for HIV/STI prevention approaches that incorporate informed decision-making about childbearing and parenting, and empowerment strategies for SWs in the context of their relationships with NPPs.

Objectives Travelling away from home presents opportunities for new sexual partnerships, which may be associated with sexually transmitted infection (STI) risk. We examined the prevalence of, and factors associated with, reporting new sexual partner(s) while overseas, and whether this differed by partners’ region of residence. Methods We analysed data from 12 530 men and women aged 16–74 years reporting ≥1 sexual partner(s) in the past 5 years in Britain's third National Survey of Sexual Attitudes and Lifestyles (Natsal-3), a probability survey undertaken 2010–2012. Results 9.2% (95% CI 8.3% to 10.1%) of men and 5.3% (4.8% to 5.8%) of women reported new sexual partner(s) while overseas in the past 5 years. This was strongly associated with higher partner numbers and other sexual and health risk behaviours. Among those with new partners while overseas, 72% of men and 58% of women reported partner(s) who were not UK residents. Compared with those having only UK partners while abroad, these people were more likely to identify as ‘White Other’ or ‘Non-White’ (vs White British ethnicity), report higher partner numbers, new partners from outside the UK while in the UK and paying for sex (men only) all in the past 5 years. There was no difference in reporting STI diagnosis/es during this time period. Conclusions Reporting new partners while overseas was associated with a range of sexual risk behaviours. Advice on sexual health should be included as part of holistic health advice for all travellers, regardless of age, destination or reason for travel. PMID:27272533

Baltimore, Maryland ranks among U.S. cities with the highest incidence of HIV infection among men who have sex with men (MSM). HIV screening at sex partner meeting places or venues frequented by MSM with new diagnoses and/or high HIV viral load may reduce transmission by identifying and linking infected individuals to care. We investigated venue-based clustering of newly diagnosed MSM to identify high HIV transmission venues. HIV surveillance data from MSM diagnosed between October 2012-June 2014 and reporting ≥1 sex partner meeting place were examined. Venue viral load was defined according to the geometric mean viral load of the cluster of cases that reported the venue and classified as high (>50,000 copies/mL), moderate (1500-50,000 copies/mL), and low (<1500 copies/mL). 143 MSM provided information on ≥1 sex partner meeting place, accounting for 132 unique venues. Twenty-six venues were reported by > 1 MSM; of these, a tightly connected cluster of six moderate viral load sex partner meeting places emerged, representing 66% of reports. Small, dense networks of moderate to high viral load venues may be important for targeted HIV control among MSM. Copyright © 2017 Elsevier Ltd. All rights reserved.

Alcohol misuse among military service members from the recent conflicts in Iraq and Afghanistan is over two times higher compared to misuse in the civilian population. Unfortunately, in addition to experiencing personal consequences from alcohol misuse, partners and family members of alcohol-misusing service members also suffer in negative ways from their loved one's drinking. These family members represent important catalysts for helping their loved ones identify problem drinking and overcoming the barriers to seeking care. This paper describes the protocol to a pilot study evaluating a 4-session, web-based intervention (WBI) for concerned partners (CPs) of service members with alcohol misuse. The WBI will be adapted from the Community Reinforcement and Family Training (CRAFT) intervention. In the first phase, we will develop and beta-test the WBI with 15-20 CPs. In the second phase, we will randomize CPs to WBI (n = 50) or to delayed-WBI (n = 50) and evaluate the impact of the WBI on CPs' perceptions of service member help-seeking and drinking, as well as the CP's well-being and relationship satisfaction 3 months after the intervention. In the third phase, we will recruit 15-20 service members whose partners have completed the study. We will interview the service members to learn how the CP-focused WBI affected them and to assess whether they would be receptive to a follow-on WBI module to help them. This project has the potential to benefit a large population of military service members who may be disproportionately affected by recent conflicts and whose drinking misuse would otherwise go undetected and untreated. It also develops a new prevention model that does not rely on service members or partners attending a hospital or clinical facility to access care. NCT02073825.

Methane-Fueled Syntrophy through Extracellular Electron Transfer: Uncovering the Genomic Traits Conserved within Diverse Bacterial Partners of Anaerobic Methanotrophic Archaea

The anaerobic oxidation of methane by anaerobic methanotrophic (ANME) archaea in syntrophic partnership with deltaproteobacterial sulfate-reducing bacteria (SRB) is the primary mechanism for methane removal in ocean sediments. The mechanism of their syntrophy has been the subject of much research as traditional intermediate compounds, such as hydrogen and formate, failed to decouple the partners. Recent findings have indicated the potential for extracellular electron transfer from ANME archaea to SRB, though it is unclear how extracellular electrons are integrated into the metabolism of the SRB partner. We used metagenomics to reconstruct eight genomes from the globally distributed SEEP-SRB1 clade of ANMEmore » partner bacteria to determine what genomic features are required for syntrophy. The SEEP-SRB1 genomes contain large multiheme cytochromes that were not found in previously described free-living SRB and also lack periplasmic hydrogenases that may prevent an independent lifestyle without an extracellular source of electrons from ANME archaea. Metaproteomics revealed the expression of these cytochromes at in situ methane seep sediments from three sites along the Pacific coast of the United States. Phylogenetic analysis showed that these cytochromes appear to have been horizontally transferred from metal-respiring members of the Deltaproteobacteria such as Geobacter and may allow these syntrophic SRB to accept extracellular electrons in place of other chemical/organic electron donors. Some archaea, known as anaerobic methanotrophs, are capable of converting methane into carbon dioxide when they are growing syntopically with sulfate-reducing bacteria. This partnership is the primary mechanism for methane removal in ocean sediments; however, there is still much to learn about how this syntrophy works. Previous studies have failed to identify the metabolic intermediate, such as hydrogen or formate, that is passed between partners. However, recent analysis of methanotrophic archaea has suggested that the syntrophy is formed through direct electron transfer. In this research, we analyzed the genomes of multiple partner bacteria and showed that they also contain the genes necessary to perform extracellular electron transfer, which are absent in related bacteria that do not form syntrophic partnerships with anaerobic methanotrophs. This genomic evidence shows a possible mechanism for direct electron transfer from methanotrophic archaea into the metabolism of the partner bacteria.« less

A qualitative study of rural black adolescents' perspectives on primary STD prevention strategies.

PubMed

Akers, Aletha Y; Gold, Melanie A; Coyne-Beasley, Tamera; Corbie-Smith, Giselle

Primary STD prevention relies on five key strategies: practicing abstinence, choosing low-risk partners, discussing partners' sexual history, using condoms consistently and not having multiple partners. Few studies have examined all of these strategies simultaneously, and few have focused on rural black adolescents, whose rates of early sexual initiation and STDs are among the highest in the nation. In 2006, a sample of 37 black adolescents (20 female, 17 male) from two rural North Carolina counties participated in focus groups that explored their understanding of how primary prevention strategies reduce STD transmission, the common barriers they encounter in trying to adopt these strategies and the risk reduction strategies that they employ. Transcripts were analyzed using a grounded theory approach. Adolescents understood how primary prevention strategies reduce STD transmission. However, they perceived sex as normal and abstinence as unlikely during adolescence. Furthermore, they considered the remaining primary prevention strategies difficult to implement because these strategies depend on partner cooperation and incorrectly assume that STD prevention is paramount when adolescents make sexual decisions. Adolescents reported using alternative strategies to reduce their STD risk; the most commonly used approaches were indirect assessments of partner characteristics (e.g., evaluating partners' physical appearance and sexual history) and STD testing (to identify and treat infections). Adolescents try to reduce their STD risk, but do so by using ineffective practices. Promoting primary prevention strategies requires helping adolescents to identify opportunities to successfully employ these strategies. Copyright © 2012 by the Guttmacher Institute.

Sexually transmitted diseases (STDs) are an important public health problem, due to their medical, social and economic repercussions. Therefore, more knowledge is needed about the sexual behaviour that promotes their spread, in order to improve control and prevention strategies. Our aim was to determine the frequency of male condom use associated with sexual behaviour factors, a history of and knowledge about STDs in a sample of the male population in Mexico City. During 1994 a cross-sectional epidemiological study was carried out, using multi-stage sampling with conglomerates, in 1377 men from 15 to 49 years old. The mean age was 34.5 years (SD 7.5 years). Mean age at first sexual relations was 17.7 years (SD 2.8 years). The global proportion of condom use during the last sexual relation was 24.6%; use according to type of female sex partner in the last year was 18.8% with regular partners and 62.5% with occasional partners. The principal predictors of male condom use, identified through statistical modelling, were: younger age (<25 years), middle and high education level (>9 years), middle and high socioeconomic level and type of sexual partners (occasional and regular). This population has risk factors for acquiring and transmitting some STDs, such as occasional sexual partners and a history of STDs. Characteristics which are important in relation to male condom use were identified, such as age (younger than 35), education (complete junior high school or more) and type of sexual partners (occasional and regular).

Cross-sectional study using a self-administered questionnaire. Primary Healthcare centers in Spain. 10,322 women (18-70 years) attending Primary Healthcare centers. A compound index was calculated based on frequency, types, and duration of Intimate Partner Violence. Multivariable adjusted logistic regression models were used to identify the sociodemographic factors, which were independently associated with each Intimate Partner Violence category. The prevalence of Intimate Partner Violence was 24.8%. For the physical only category, no differences were observed regarding education or employment status, and women with the highest income have less risk. For the psychological only category, no differences were observed according to the income level. The risk increases as the education level decreases, and the greatest frequency of only psychological Intimate Partner Violence was observed in women who were unemployed or students. For both the physical and psychological category of Intimate Partner Violence, a clear risk increase is observed as income and education levels decrease. Retired women showed the highest frequency of this violence category. The results show that Intimate Partner Violence affects women of all social strata, but the frequency and Intimate Partner Violence category will vary according to the socio-economic.

Abstract: Background: Suicide is the 10th leading cause of death in the United States. Furthermore, intimate partner problems are amid the top precipitating circumstances among suicide decedents. The aim of this study was to determine circumstantial associations of intimate partner problem-related suicides in suicide decedents in Kentucky. Methods: All suicides that were reported to the Kentucky Violent Death Reporting System between 2005 and 2012 were eligible for this study. Multiple logistic regression was used to explore predictors (precipitating health-related problems, life stressors, and criminal/legal issues) of intimate partner problem-related suicides. Results: Of the 4,754 suicides, included in this study, approximately 17% had intimate partner problems prior to suicide. In the adjusted analysis, mental health issues, alcohol problems, history of suicides attempts, suicides precipitated by another crime, and other legal problems increased the odds of having an intimate partner-related suicide. However, having physical health problems, prior to the suicide, decreased the odds of intimate partner-related suicide. Conclusions: These results provide insight for the development of suicide interventions for individuals with intimate partner problems by targeting risk factors that are prevalent among this population. Moreover, these results may help marriage/relationship and/or family/divorce court representatives identify individuals with intimate partner problems more at risk for suicide and alleviate the influence these suicide risk factors have on individuals experiencing Intimate partner problems.

To assess whether partner disengagement from pregnancy is associated with adverse maternal and infant outcomes. We analyzed data from the 2006-2007 Canadian Maternity Experiences Survey, comprising a cross-sectional representative sample of 6,421 childbearing women. Multiple logistic regression assessed the association between adverse outcomes and three indicators of partner disengagement: (1) partner did not want the pregnancy, (2) partner argued more than usual in the year prior to the baby's birth, and (3) partner was absent at the delivery. Of all respondents, 3.8% had partners who did not want the pregnancy, 16.1% argued more than usual with their partner in the past year, and 7.6% had partners who were absent at the delivery. Women whose partner did not want the pregnancy were more likely to report intimate partner violence (IPV) (adjusted odds ratio [AOR] 3.55; 95% confidence interval [95% CI] 2.36-5.14), elevated depressive symptoms in the extended postpartum period (AOR 2.56, 95% CI 1.70-3.83), and nonroutine child healthcare visits after birth (AOR 1.54, 95% CI 1.13-2.11). Women whose partner argued more in the past year had higher odds of IPV (AOR 4.82, 95% CI 3.69-6.30), elevated depressive symptoms in the extended postpartum period (AOR 3.63; 95% CI 2.84-4.64), and nonroutine child healthcare visits (AOR 1.49, 95% CI 1.26-1.77), after adjustment for potential confounders. Partner disengagement is common and is associated with adverse maternal and infant outcomes. Affected women may benefit from special assistance during pregnancy and after delivery.

Preliminary evaluation of an analog procedure to assess acceptability of intimate partner violence against women: the Partner Violence Acceptability Movie Task

PubMed Central

Gracia, Enrique; Rodriguez, Christina M.; Lila, Marisol

2015-01-01

Acceptability of partner violence against women is a risk factor linked to its perpetration, and to public, professionals’ and victims’ responses to this behavior. Research on the acceptability of violence in intimate partner relationships is, however, limited by reliance solely on self-reports that often provide distorted or socially desirable accounts that may misrepresent respondents’ attitudes. This study presents data on the development and initial validation of a new analog task assessing respondents’ acceptability of physical violence toward women in intimate relationships: the Partner Violence Acceptability Movie Task (PVAM). This new analog task is intended to provide a more implicit measure of the acceptability of partner violence against women. For this analog task, clips were extracted from commercially available films (90-s segments) portraying partner violence. Two independent samples were used to develop and evaluate the PVAM: a sample of 245 undergraduate students and a sample of 94 male intimate partner violence offenders. This new analog task demonstrated acceptable internal consistency. Results also indicated adequate construct validity. Both perpetrators and undergraduates scoring high in the PVAM also scored higher in self-reported justifications of partner abuse. Perpetrators of partner violence scored significantly higher in acceptability of partner violence than the undergraduate sample (both male and female students), and male students scored higher than females. These preliminary results suggest that the PVAM may be a promising tool to assess the acceptability of violence in intimate partner relationships, highlighting the need to consider alternatives to self-report to evaluate potential beliefs about partner violence.

The present study was aimed to extend the self-orientation model (Campbell, 1999) to vulnerable narcissism in a collectivistic culture. Two hundred and twenty-seven college students were recruited from China. Participants reported their ratings on measures of vulnerable and grandiose narcissism, attractions to different (caring vs perfect) targets, and their choices of potential romantic partners. Results indicated that those participants classified as grandiose or vulnerable narcissists were more attracted to perfect targets than non-narcissists. In addition, grandiose narcissists preferred to choose perfect targets as their romantic partners, while vulnerable narcissists did not show such a preference when choosing potential partners. These results suggested that culture could influence the function of narcissism. The self-orientation model could not fully explain the choices of vulnerable narcissists.

Huntington's disease (HD) is a devastating central nervous system disorder. Even though the gene responsible has been positionally cloned recently, its etiology has remained largely unclear. To investigate potential disease mechanisms, we conducted a search for binding partners of the HD-protein huntingtin. With the yeast two-hybrid system, one such interacting factor, the huntingtin interacting protein-1 (HIP-1), was identified (Wanker et al. 1997; Kalchman et al. 1997) and the human gene mapped to 7q11.2. In this paper we demonstrate the localization of the HIP1 mouse homologue (Hip1) into a previously identified region of human-mouse synteny on distal mouse Chromosome (Chr) 5, both employing an IRS-PCR-based mapping strategy and traditional fluorescent in situ hybridization (FISH) mapping.

Differential Gene Expression During Compensatory Sprouting of Dendrites in the Auditory System of the Cricket Gryllus bimaculatus

Neurons that lose their pre-synaptic partners due to injury usually retract or die. However, when the auditory interneurons of the cricket are denervated, dendrites respond by growing across the midline and forming novel synapses with the opposite auditory afferents. Suppression subtractive hybridization was used to detect transcriptional changes three days after denervation. This is a stage at which we demonstrate robust compensatory dendritic sprouting. While 49 unique candidates were downregulated, no sufficiently upregulated candidates were identified at this time point. Several candidates identified in this study are known to influence the translation and degradation of proteins in other systems. The potential role of these factors in the compensatory sprouting of cricket auditory interneurons in response to denervation is discussed. PMID:19453768

People with multiple sex partners tend to forget a significant proportion when recalling them. Randomized trial of supplementary interviewing techniques during routine partner notification contact interviews for chlamydia, gonorrhea, and syphilis in Colorado Springs, CO. Cases with multiple sex partners in the last 3 months (n = 123) participated. Interviewers prompted nonspecifically and read back the list of elicited partners after cases recalled partners on their own. We then randomly assigned cases to receive 1 of 3 sets of recall cues: (1) an experimental set of cues consisting of locations where people meet partners, role relationships, network ties, and first letters of names; (2) another experimental set including common first names; and (3) control cues referring to individual characteristics (e.g., physical appearance). Nonspecific prompting and reading back the list each increased the number of additional partners elicited and located by 3% to 5% on average. On average, the combined location/role/letter/network cues elicited more additional partners (0.57) than did the first-name (0.29) and individual characteristics (0.28) cues. The location and first-name cues were the most effective in eliciting located partners. The supplementary techniques increased the number of new cases found by 12% and, importantly, identified branches of the sexual network that would not otherwise have been discovered. Elicitation of sex partners can be enhanced in contact interviews with simple interviewing techniques, resulting in improved network ascertainment and sexually transmitted disease case finding.

Older adults account for 17% of new HIV diagnoses in the US and are more likely to be diagnosed with HIV later in the course of the disease compared to younger people. We calculated the prevalence and associated factors of having ever been tested for HIV among sexually active older adults. We analyzed data from the 2008-2016 General Social Survey Limited to respondents ≥65 years of age who reported more than one sex partner(s) in past 12 months (n = 757). HIV testing prevalence, prevalence ratios, and 95% confidence intervals were calculated by demographic variables and HIV-related risk behaviors. An estimated 16.3% of sexually active older adults have tested for HIV, and 15.9% were at increased risk for HIV infection (reported injection drug and/or crack-cocaine use, exchanging money for sex, more than three sex partners in the past year, or men who reported having sex with another man). In the adjusted model, adults aged 65-70, not married, self-identified as gay/bisexual, and at increased risk for HIV infection were more likely to have tested for HIV. An estimated 83.7% of sexually active older adults never tested for HIV. Strategies are needed to increase HIV awareness and testing among potentially high-risk older adults.

The increasing prevalence in Southeast Asia of Plasmodium falciparum infections with delayed parasite clearance rates, following treatment of malaria patients with the artemisinin derivative artesunate, highlights an urgent need to identify which of the currently available artemisinin-based combination therapies (ACTs) are most suitable to treat populations with emerging artemisinin resistance. Here, we demonstrate that the rodent Plasmodium berghei SANA strain has acquired artemisinin resistance following drug pressure, as defined by reduced parasite clearance and early recrudescence following daily exposure to high doses of artesunate or the active metabolite dihydroartemisinin. Using the SANA strain and the parental drug-sensitive N strain, we have interrogated the antimalarial activity of five ACTs, namely, artemether-lumefantrine, artesunate-amodiaquine, artesunate-mefloquine, dihydroartemisinin-piperaquine, and the newest combination artesunate-pyronaridine. By monitoring parasitemia and outcome for 30 days following initiation of treatment, we found that infections with artemisinin-resistant P. berghei SANA parasites can be successfully treated with artesunate-pyronaridine used at doses that are curative for the parental drug-sensitive N strain. No other partner drug combination was as effective in resolving SANA infections. Of the five partner drugs tested, pyronaridine was also the most effective at suppressing the recrudescence of SANA parasites. These data support the potential benefit of implementing ACTs with pyronaridine in regions affected by artemisinin-resistant malaria. PMID:24145526

Couples coping with cardiovascular disease: A systematic review.

Cardiovascular disease (CVD) is the leading cause of death for both men and women. Its potential ramifications on all aspects of life, for patients and partners, are just beginning to be understood. Although research has focused on the individual who has received the diagnosis, relatively little is known about how couples manage CVD. This article presents a systematic review of literature that focuses on how couples cope with one partner's CVD diagnosis. A systematic review is warranted to orient practitioners, policy makers, and researchers to the state of existing knowledge and its gaps and to identify what still needs to be done. Data were extracted from 25 peer-reviewed articles that met our inclusion criteria. Content examined included theory integration, coping constructs and instruments, samples, analyses, and findings. Most articles successfully integrated theory in the studies' respective conceptualizations and designs. Most used valid and reliable instruments to measure coping. Principal limitations included problematic sampling strategies and analysis techniques, thereby limiting external validity. Principal implications of this review's findings relate to our fields' need to provide more care focused on dyads (vs. individual patients), adopt an integrated model in health care, and conduct systemic, longitudinal research to gain a better grasp on how coping changes over time. Doing so will serve to better equip providers in the support of patients and partners living with CVD. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

The Pacific Regional Cancer Coalition (PRCC) provides regional leadership in the U.S. Affiliated Pacific Islands (USAPI) to implement the Regional Comprehensive Control Plan: 2007-2012, and to evaluate its coalition and partnerships. The Pacific Center of Excellence in the Elimination of Disparities (CEED), aims to reduce cancer disparities and conducts evaluation activities relevant to cancer prevention and control in the USAPI. The PRCC Self (internal) and Partner (external) Assessments were conducted to assess coalition functioning, regional and national partnerships, sustainability, and the role of regionalism for integrating all chronic disease prevention and control in the Pacific. Self-administered questionnaires and key informant telephone interviews with PRCC members (N=20), and representatives from regional and national partner organizations were administered (N=26). Validated multi item measures using 5-point scales on coalition and partnership characteristics were used. Chronbach's alphas and averages for the measures were computed. Internal coalition measures: satisfaction (4.2, SD=0.48) communication (4.0, SD=0.56), respect (4.0, SD=0.60) were rated more highly than external partnership measures: resource sharing (3.5, SD=0.74), regionalism (3.9, SD=0.47), use of findings (3.9, SD=0.50). The PRCC specifically identified its level of "collaboration" with external partners including Pacific CEED. External partners identified its partnership with the PRCC in the "coalition" stage. PRCC members and external partners are satisfied with their partnerships. All groups should continue to focus on building collaboration with partners to reflect a truly regional approach to sustain the commitment, the coalitions and the programming to reduce cancer in the USAPI. PRCC and partners should also work together to integrate all chronic disease prevention and control efforts in the Pacific.

Introduction National Comprehensive Cancer Control Program (NCCCP) awardees are encouraged to work with partners (eg, nonprofit organizations) to develop and implement plans to reduce the cancer burden in their jurisdictions using evidence-based practices (EBPs). However, the extent of EBP use among awardees and their partners is not well understood. Methods From March through July 2012, we conducted a web-based survey of program partners referred by NCCCP program directors who were involved in implementation of cancer control plans. Results Approximately 53% of referred partners (n = 83) completed surveys, 91.6% of whom represented organizations. Most partners reported involvement in helping to identify (80.5%), adapt (81.7%), implement (90.4%), and evaluate (81.9%) EBPs. The factors rated most frequently as very important when selecting EBPs were “consistent with our organization’s mission” (89.2%) and “cost-effective” (81.9%). Although most respondents said that their organizations understood the importance of using EBPs (84.3%) and had adequate access to cancer registry data (74.7%), few reported having sufficient financial resources to develop new EBPs (7.9%). The most frequently mentioned benefit of using EBPs was that they are proven to work. Resource limitations and difficulty adapting EBPs for specific populations and settings were challenges. Conclusions Our findings help indicate how NCCCP partners are involved in using EBPs and can guide ongoing efforts to encourage the use of EBPs for cancer control. The challenges of using EBPs that partners identified highlight the need to improve strategies to translate cancer prevention and control research into practice in real-world settings and for diverse populations.

Hypersomnia causes significant socioeconomic burden, but there is insufficient information about the time course and the effect on the partner. The aim of this study was to estimate the factual direct and productivity costs of hypersomnia in a controlled study including all national patients and their partners. Using records from the Danish National Patient Registry (1997-2009), we identified all patients with a diagnosis of hypersomnia and compared these patients and their partners with randomly chosen controls matched for age, gender, geographic area and marital status. Direct and productivity costs, including frequencies of primary and sector contacts and procedures, medication, labour supply and social transfer payments were extracted from the national databases. A total of 2,855 national patients was compared to 11,382 controls. About 70 % of patients and controls were married or cohabiting. Patients with hypersomnia had significantly higher rates of health-related contact, medication use and socioeconomic cost. Furthermore, they had slightly lower employment rates, and those in employment had a lower income level than control subjects. The annual mean excess health-related cost including social transfers was 3,498 for patients with hypersomnia and 3,851 for their partners. The social and health-related consequences could be identified up to 11 years before the first diagnosis among both the patients and their partners and became more pronounced as the disease advanced. The health effects were present in all age groups and in both genders. On the basis of this retrospective controlled study in the Danish population, symptoms and findings of hypersomnia are associated with major socioeconomic consequences for patients, their partners and society.

The genus Mycobacterium encompasses over one hundred named species of environmental and pathogenic organisms, including the causative agents of devastating human diseases such as tuberculosis and leprosy. The success of these human pathogens is due in part to their ability to rapidly adapt to their changing environment and host. Recombination is the fastest way for bacterial genomes to acquire genetic material, but conflicting results about the extent of recombination in the genus Mycobacterium have been reported. We examined a data set comprising 18 distinct strains from 13 named species for evidence of recombination. Genomic regions common to all strains (accounting for 10% to 22% of the full genomes of all examined species) were aligned and concatenated in the chromosomal order of one mycobacterial reference species. The concatenated sequence was screened for evidence of recombination using a variety of statistical methods, with each proposed event evaluated by comparing maximum-likelihood phylogenies of the recombinant section with the non-recombinant portion of the dataset. Incongruent phylogenies were identified by comparing the site-wise log-likelihoods of each tree using multiple tests. We also used a phylogenomic approach to identify genes that may have been acquired through horizontal transfer from non-mycobacterial sources. The most frequent associated lineages (and potential gene transfer partners) in the Mycobacterium lineage-restricted gene trees are other members of suborder Corynebacterinae, but more-distant partners were identified as well. In two examined cases of potentially frequent and habitat-directed transfer (M. abscessus to Segniliparus and M. smegmatis to Streptomyces), observed sequence distances were small and consistent with a hypothesis of transfer, while in a third case (M. vanbaalenii to Streptomyces) distances were larger. The analyses described here indicate that whereas evidence of recombination in core regions within the genus is relatively sparse, the acquisition of genes from non-mycobacterial lineages is a significant feature of mycobacterial evolution.

Fragment-Based Screening of a Natural Product Library against 62 Potential Malaria Drug Targets Employing Native Mass Spectrometry

2018-01-01

Natural products are well known for their biological relevance, high degree of three-dimensionality, and access to areas of largely unexplored chemical space. To shape our understanding of the interaction between natural products and protein targets in the postgenomic era, we have used native mass spectrometry to investigate 62 potential protein targets for malaria using a natural-product-based fragment library. We reveal here 96 low-molecular-weight natural products identified as binding partners of 32 of the putative malarial targets. Seventy-nine (79) fragments have direct growth inhibition on Plasmodium falciparum at concentrations that are promising for the development of fragment hits against these protein targets. This adds a fragment library to the published HTS active libraries in the public domain. PMID:29436819

2012-09-01

The present study set out to investigate predictors of first time adolescent peer-on-peer sexual victimization (APSV) among 238 female Grade 9 students from 30 schools in Denmark. A prospective research design was utilized to examine the relationship among five potential predictors as measured at baseline and first time APSV during a 6-month period. Data analysis was a binary logistic regression analysis. Number of sexual partners and displaying sexual risk behaviors significantly predicted subsequent first time peer-on-peer sexual victimization, whereas a history of child sexual abuse, early sexual onset and failing to signal sexual boundaries did not. The present study identifies specific risk factors for first time sexual victimization that are potentially changeable. Thus, the results may inform prevention initiatives targeting initial experiences of APSV.

HIV disproportionately affects African American men who have sex with men (MSM) in the United States. To inform this epidemiological pattern, we examined cross-sectional sexual behavior data in 509 African American MSM. Bivariate logistic regression analyses were conducted to examine the extent to which age, education,and sexual identity explain the likelihood of engaging in sex with a partner of a specific gender and the likelihood of engaging in unprotected sexual behaviors based on partner gender. Across all partner gender types,unprotected sexual behaviors were more likely to be reported by men with lower education. Younger, non-gay identified men were more likely to engage in unprotected sexual behaviors with transgender partners, while older, non-gay identified men were more likely to engage in unprotected sexual behaviors with women. African American MSM do not represent a monolithic group in their sexual behaviors, highlighting the need to target HIV prevention efforts to different subsets of African American MSM communities as appropriate.

Correlates of male cohabiting partner's involvement in child-rearing tasks in low-income urban Black stepfamilies.

Cohabitation is a family structure experienced by many Black children. This study examines the link between family relationships (child relationship with mother and the cohabiting partner; parent and cohabiting partner relationship) and involvement of biologically unrelated male cohabiting partners (MCP) in child rearing. The participants were 121 low-income urban Black families consisting of a single mother, MCP, and an adolescent (56% female, M age = 13.7). Assessments were conducted individually with mothers, MCPs, and adolescents via measures administered by interview. MCPs were involved in both domains of child rearing assessed (daily child-related tasks and setting limits) and those identified as coparents by the mother were more involved in child-rearing tasks than those not identified as coparents. Using structural equation modeling (SEM), the mother-MCP relationship (both support and conflict) and the adolescent-MCP relationship were related to MCP's involvement in both domains of child rearing. The findings indicate that MCPs are actively involved in child rearing and family relationship variables are associated with their involvement in these tasks.

A sex-specific trade-off between mating preferences for genetic compatibility and body size in a cichlid fish with mutual mate choice.

2012-08-07

Mating preferences for genetic compatibility strictly depend on the interplay of the genotypes of potential partners and are therein fundamentally different from directional preferences for ornamental secondary sexual traits. Thus, the most compatible partner is on average not the one with most pronounced ornaments and vice versa. Hence, mating preferences may often conflict. Here, we present a solution to this problem while investigating the interplay of mating preferences for relatedness (a compatibility criterion) and large body size (an ornamental or quality trait). In previous experiments, both sexes of Pelvicachromis taeniatus, a cichlid fish with mutual mate choice, showed preferences for kin and large partners when these criteria were tested separately. In the present study, test fish were given a conflicting choice between two potential mating partners differing in relatedness as well as in body size in such a way that preferences for both criteria could not simultaneously be satisfied. We show that a sex-specific trade-off occurs between mating preferences for body size and relatedness. For females, relatedness gained greater importance than body size, whereas the opposite was true for males. We discuss the potential role of the interplay between mating preferences for relatedness and body size for the evolution of inbreeding preference.

Social thermoregulation as a potential mechanism linking sociality and fitness: Barbary macaques with more social partners form larger huddles.

2018-04-17

Individuals with more or stronger social bonds experience enhanced survival and reproduction in various species, though the mechanisms mediating these effects are unclear. Social thermoregulation is a common behaviour across many species which reduces cold stress exposure, body heat loss, and homeostatic energy costs, allowing greater energetic investment in growth, reproduction, and survival, with larger aggregations providing greater benefits. If more social individuals form larger thermoregulation aggregations due to having more potential partners, this would provide a direct link between sociality and fitness. We conducted the first test of this hypothesis by studying social relationships and winter sleeping huddles in wild Barbary macaques (Macaca sylvanus), wherein individuals with more social partners experience greater probability of winter survival. Precipitation and low temperature increased huddle sizes, supporting previous research that huddle size influences thermoregulation and energetics. Huddling relationships were predicted by social (grooming) relationships. Individuals with more social partners therefore formed larger huddles, suggesting reduced energy expenditure and exposure to environmental stressors than less social individuals, potentially explaining how sociality affects survival in this population. This is the first evidence that social thermoregulation may be a direct proximate mechanism by which increased sociality enhances fitness, which may be widely applicable across taxa.

Background eHealth resources for people facing health crises must balance the expert knowledge and perspective of developers and clinicians against the very different needs and perspectives of prospective users. This formative study explores the information and support needs of posttreatment prostate cancer patients and their partners as a way to improve an existing eHealth information and support system called CHESS (Comprehensive Health Enhancement Support System). Methods Focus groups with patient survivors and their partners were used to identify information gaps and information-seeking milestones. Results Both patients and partners expressed a need for assistance in decision making, connecting with experienced patients, and making sexual adjustments. Female partners of patients are more active in searching for cancer information. All partners have information and support needs distinct from those of the patient. Conclusions Findings were used to develop a series of interactive tools and navigational features for the CHESS prostate cancer computer-mediated system. PMID:22591675

We examined correlates of love and trust among female sex workers and their noncommercial male partners along the Mexico-US border. From 2011 to 2012, 322 partners in Tijuana and Ciudad Juárez, Mexico, completed assessments of love and trust. Cross-sectional dyadic regression analyses identified associations of relationship characteristics and HIV risk behaviors with love and trust. Within 161 couples, love and trust scores were moderately high (median 70/95 and 29/40 points, respectively) and correlated with relationship satisfaction. In regression analyses of HIV risk factors, men and women who used methamphetamine reported lower love scores, whereas women who used heroin reported slightly higher love. In an alternate model, men with concurrent sexual partners had lower love scores. For both partners, relationship conflict was associated with lower trust. Love and trust are associated with relationship quality, sexual risk, and drug use patterns that shape intimate partners' HIV risk. HIV interventions should consider the emotional quality of sex workers' intimate relationships.

This study explored perceptions of partner body image preferences and symptoms of disordered eating in gay and heterosexual men. Participants were male college students (n = 201; M age = 20.46), and over one third identified as gay. We compared discrepancies between participants' current and ideal body type and participants' current body type and the body type they believed they should have to attract a dating partner. For gay men, the discrepancy between their current body and the body they believed they should have to attract a dating partner was significantly greater than the discrepancy between their current and ideal body types. In gay and heterosexual men, the discrepancy between current body and the body they believed they should have to attract a dating partner predicted eating, shape, and weight concern. Results suggest that perceptions of partner body image preferences may contribute to eating disorder pathology in men.

Mississippi has among the highest prevalence of sexually transmitted infections (STIs) in the United States. Understanding sexual networks can provide insight into risk factors for transmission and guide prevention interventions. Participants included 1437 primarily African American (95%) adults presenting for care at an STI clinic in Jackson, Mississippi. Latent class analysis identified underlying population subgroups with unique patterns of response on a comprehensive set of 14 sexual partner variables, such as living with or having a child with a partner, partner dependence and trust, 1-time sexual encounters, multiple main partners, substance use, sexual concurrency, and incarceration. Classes were compared on participant age, sex, sexual orientation, public assistance, lifetime partners, relationship status, and self-reported past-year STI. Three classes emerged. Class 1 (n = 746) participants were less dependent on partners and less likely to live with or have a child with a partner. Class 2 participants (n = 427) endorsed multiple STI risk factors, including partner incarceration, 6 or more lifetime partners, sexual concurrency, 1-time sexual encounters, and substance use at last sex. Class 3 participants (n = 226) were more likely to be in dependent, committed relationships with children. Class 2 had a higher proportion of self-report past-year STIs (36.7%) compared with classes 1 (26.6%) and 3 (26.1%). Certain partner factors such as incarceration, substance use, and concurrency may contribute to increased STI risk. Partner factors may be useful proxies for STI risks and could be useful questions to include in screening questionnaires in clinical settings.

The physical health detriments associated with adolescent females' having older romantic partners are well documented. However, little is known about the relationship between having an older partner and females' subsequent mental health. Two waves of data from 1,440 participants in the National Longitudinal Study of Adolescent Health were analyzed. The sample was restricted to females in grades 7-12 who had not had sex at Wave 1 (1994-1995) and reported at least one romantic relationship by Wave 2 (1996). A lagged dependent variable approach with ordinary least-squares regression measured changes in depression and self-esteem associated with sexual and nonsexual relationships with same-age and older partners. Intimate partner violence was tested as a mediator. Compared with respondents reporting a nonsexual relationship with a same-age partner, those reporting a nonsexual relationship with an older partner, sex with a same-age partner or sex with an older partner experienced greater increases in depression between surveys; mean predicted depression levels at Wave 2 ranged from 7.7 to 9.0 across these groups (possible range, 0-27). Intimate partner violence explained one-third of the difference between those who had had sex and those who had not had sex with same-age partners. Fewer associations were found for self-esteem, and differences between groups were small. Health correlates of adolescent sexual behavior go beyond physical health outcomes. Future research should identify mechanisms through which relationships, especially those with older partners, are associated with declines in mental health.

The function of Kennedy Space Center's Center Planning and Development (CPD) directorate is to develop partnerships with the commercial space industry, academia, and other non-NASA government agencies to use KSC's facilities, technical capabilities, technologies and expertise, while building on existing partnerships. As an intern for the Spaceport Planning Office within the CPD, I played an essential part in promoting these opportunities by assisting the Marketing Specialist with organizing CPD's multi-booth exhibit for KSC's 2014 Innovation Expo. I was also responsible for gathering/reviewing video clips of interviews from existing partners to be used as potential footage for video testimonials that would be used to educate the public on KSC. My last project was to develop a standard presentation highlighting the benefits and potential of partnering with KSC, which would be used by KSC partnership development managers (PDMs) when presenting externally to potential partners. With these various projects and limited timeframe to complete each, learning to effectively manage my time and actively multitask was imperative.

Protein-protein docking protocols aim to predict the structures of protein-protein complexes based on the structure of individual partners. Docking protocols usually include several steps of sampling, clustering, refinement and re-scoring. The scoring step is one of the bottlenecks in the performance of many state-of-the-art protocols. The performance of scoring functions depends on the quality of the generated structures and its coupling to the sampling algorithm. A tool kit, GRADSCOPT (GRid Accelerated Directly SCoring OPTimizing), was designed to allow rapid development and optimization of different knowledge-based scoring potentials for specific objectives in protein-protein docking. Different atomistic and coarse-grained potentials can be created by a grid-accelerated directly scoring dependent Monte-Carlo annealing or by a linear regression optimization. We demonstrate that the scoring functions generated by our approach are similar to or even outperform state-of-the-art scoring functions for predicting near-native solutions. Of additional importance, we find that potentials specifically trained to identify the native bound complex perform rather poorly on identifying acceptable or medium quality (near-native) solutions. In contrast, atomistic long-range contact potentials can increase the average fraction of near-native poses by up to a factor 2.5 in the best scored 1% decoys (compared to existing scoring), emphasizing the need of specific docking potentials for different steps in the docking protocol.

Despite the potential importance of communication about genetic testing between test participants and their significant others, little is known about social support and communication between women undergoing BRCA1 and BRCA2 testing and their partners. The aims of this longitudinal study were to examine communication about genetic testing during and following testing and to evaluate whether communication is associated with psychological distress reported by test participants and their partners. Participants were 153 women who were undergoing genetic testing and 118 partners of women undergoing testing. Relationship communication and distress were evaluated at the time of pretest education and 6 months postdisclosure. Overall, the decision to undergo testing was discussed by the majority of test participants and partners, and most couples felt their partners were supportive. Most women disclosed their results to their partners. Longitudinal analyses suggested that less support and protective buffering were associated with greater distress 6 months postdisclosure among test participants, whereas lower comfort in sharing concerns and partner support were associated with lower distress 6 months postdisclosure among partners. The results of this study suggest that the majority of couples respond supportively during the test experience, but for a small subset of couples the process can strain the relationship. Partner support during this process is important, particularly for test participants dealing with an uninformative test result.

Guided by concepts from a relational developmental perspective, this study examined intra- and interpersonal associations between self-esteem and depressive symptoms in a sample of 1,407 couples surveyed annually across 6 years in the Panel Analysis of Intimate Relations and Family Dynamics (pairfam) study. Autoregressive cross-lagged model results demonstrated that self-esteem predicted future depressive symptoms for male partners at all times, replicating the vulnerability model for men (low self-esteem is a risk factor for future depression). Additionally, a cross-partner association emerged between symptoms of depression: Higher depressive symptoms in one partner were associated with higher levels of depression in the other partner one year later. Finally, supportive dyadic coping, the support that partners reported providing to one another in times of stress, was tested as a potential interpersonal mediator of pathways between self-esteem and depression. Female partners' higher initial levels of self-esteem predicted male partners' subsequent reports of increased supportive dyadic coping, which, in turn, predicted higher self-esteem and fewer symptoms of depression among female partners in the future. Male partners' initially higher symptoms of depression predicted less frequent supportive dyadic coping subsequently reported by female partners, which was associated with increased feelings of depression in the future. Couple relations represent an important contextual factor that may be implicated in the developmental pathways connecting self-esteem and symptoms of depression.

The revictimization of women during the life cycle has attracted the interest of many researchers in recent years. In this study, we examined the relationship between the experience of child abuse and the subsequent victimization by a male partner in adulthood. Specifically, we proposed that childhood abuse experiences negatively affect the development of healthy interpersonal relationships in adulthood. Thus, some female victims of child abuse are more likely to select potentially abusive intimate male partners. Data from 23,863 heterosexual women from the 28 countries of the European Union who were living with their partners at the time of the study were used. We investigated the association between child abuse, partner's adherence to traditional gender roles, and general violence and intimate partner violence (IPV) against women. Multilevel structural equation modeling (MSEM) results indicated that child abuse is positively related to the partner's traditional gender role and general violence, which in turn predict IPV. Countries' level of human development was found to affect this process. We found support for the hypothesis that child abuse is related to IPV partially because it influences partner selection in adulthood. Thus, when they become adults, girls abused in childhood tend to select partners who are either traditional or generally violent. There is a persistent influence of social structural conditions (i.e., country's human development) throughout this process.

Background Latinas with breast cancer suffer symptom and psychosocial health disparities. Effective interventions have not been developed for or tested in this population. Purpose We describe community-based participatory research methods used to develop and implement the Nuevo Amanecer program, a culturally tailored, peer-delivered cognitive-behavioral stress management intervention for low-income Spanish-speaking Latinas with breast cancer, and unique considerations in implementing a randomized controlled trial to test the program in community settings. Methods We applied an implementation science framework to delineate the methodological phases used to develop and implement the Nuevo Amanecer program and trial, emphasizing community engagement processes. Results In phase 1, we established project infrastructure: academic and community Co-Principal Investigators, community partners, community advisory board, steering committee, and funding. In phase 2, we identified three program inputs: formative research, a community best practices model, and an evidence-based intervention tested in non-Latinas. In phase 3, we created the new program by integrating and adapting intervention components from the three sources, making adaptations to accommodate low-literacy, Spanish language, cultural factors, community context, and population needs. In phase 4, we built community capacity for the program and trial by training field staff (recruiters and interventionists embedded in community sites), compensating field staff, and creating a system for identifying potential participants. In phase 5, we implemented and monitored the program and trial. Engaging community partners in all phases has resulted in a new, culturally tailored program that is suitable for newly diagnosed Latinas with breast cancer and a trial that is acceptable and supported by community and clinical partners. Lessons Learned Engagement of community-based organizations and cancer survivors as research partners and hiring recruiters and interventionists from the community were critical to successful implementation in community settings. Having culturally and linguistically competent research staff with excellent interpersonal skills facilitated implementation. Facilitating and maintaining excellent communication among community partners was imperative to troubleshoot implementation issues. Randomization was challenging due to community concerns about assigning women to a control group. Patient privacy regulations and the need for extensive outreach to establish relationships between community partners and clinical sites hampered initial recruitment. Limitations These were resource-intensive processes to develop and implement the program that need to be compared to less intensive alternatives. Conclusions Engaging community members in design and implementation of community-based programs and trials enhances cultural appropriateness and congruence with the community context. If the randomized trial demonstrates that the intervention is effective, it will fill a gap in evidence-based programs to address ethnic disparities in quality of life among Spanish-speaking Latinas with breast cancer.

HIV continues to disproportionately affect men who have sex with men (MSM). Depression and substance use have been shown to be risk factors of partner violence among male same-sex couples. However, research exploring the risk factors for partner violence victimization after HIV disclosure among MSM is limited. The aim of this study was to determine the association between depressive symptoms, substance use, and disclosure-associated verbal and/or physical violence from a partner among MSM. Data were obtained from 340 HIV-positive MSM. Multivariable logistic regression was used to determine the associations between Center for Epidemiologic Studies-Depression (CES-D) and substance use scores, and disclosure-associated partner violence. After adjusting for age and income, every one-unit increase in substance use scores resulted in a 9% (OR=1.09; 95% CI: 1.01 – 1.16) increase in the odds of disclosure-associated partner violence. HIV disclosure interventions for MSM populations should address substance use and potential violence from partners after disclosure. PMID:26122650

We investigate coevolution dynamics of both individual strategies and social ties as they adapt within the snowdrift game with mixed strategies. We propose a partner selection mechanism based on the concept of trust. Here trust is considered an instrument for an individual both selecting the right partners and being selected amongst other potential partners. Based on her local views of the system, the focal individual dismisses the link from the partner with the lowest trust and rewires to the partner’s partner with the highest trust. It is shown that such a trust-based partner switching mechanism favors the emergence of cooperators. Furthermore, when the number of an individual’s partners is restricted (which is a metaphor of limited capacities and capabilities of an individual in real environments), surprising assortative mixing patterns are formed in the emerging network and change the network’s degree distribution from a power-law distribution to an asymmetrically U-shaped distribution. This plays a leading role in preventing global avalanches triggered by perturbations acting on the state of the highly connected individuals.

Screening for and treating intimate partner violence in the workplace.

The WHO has declared that violence is a leading worldwide public health problem with intimate partner violence one of the most common forms of violence against women (2002). Health care providers are frequently among the first to see victims of intimate partner violence and must strive to provide appropriate and effective care to abused women. Violence by intimate partners can be prevented. Occupational health nurses have a unique opportunity to intervene with abused women. Routine screening for intimate partner violence increases the likelihood of violence identification, leading to early intervention that may prevent trauma and injury. Occupational health nurses can foster a caring and confidential workplace where abused women feel safe to disclose the violence in their lives and trust that the nurse will provide treatment. A safe and healthy workplace, where abused women feel comfortable disclosing intimate partner violence and seeking treatment may also protect coworkers from the stress and violence that may potentially affect them. Occupational health nurses need to add screening for and treatment of intimate partner violence to their current health promotion and prevention activities to benefit all employees.

Growing evidence identifies adverse health effects for children who witness intimate partner violence at home. Research has also identified that women seeking elective pregnancy termination are at high risk for partner violence. However, little is known about the risk for violence exposure among the children of women seeking elective pregnancy termination. We conducted a cross-sectional study of 957 women seeking elective pregnancy termination at a large family planning clinic. All subjects completed a 10-minute, anonymous questionnaire administered by computer in a private room. Our main outcome was 12-month prevalence of physical and/or sexual violence by a current or former partner using the Abuse Assessment Screen instrument. The presence of children under the age of 18 living with the respondent was the main exposure variable. Women with children in the home had more than twice the odds of reporting physical and/or sexual IPV in the past year than women with no children, controlling for age (AOR: 2.23; 95% CI: 1.41-3.85). The increased odds of IPV among women with children as compared to women with no children was present across nearly all sociodemographic and lifestyle characteristics, and significantly higher for the youngest women (18-20 years). The highest odds for abuse occurred among women with children living at home, in a current relationship but not living with their current partner, and abused by a former partner (AOR = 10.9; 95% CI: 3.07-38.4). Nearly one of every 14 children identified in this study lived in a home with IPV. These findings support the development of IPV interventions that are family-centered, as well as the integration of trauma-informed care into healthcare settings. Healthcare visits for contraception and pregnancy termination may be ideal opportunities for implementation of screening and family violence interventions.

Geosocial networking applications (GSN apps) used for meeting sexual partners have become increasingly popular with men who have sex with men (MSM) since 2009. The current study aimed to determine if self-identified HIV-negative, MSM clinic attendees who used GSN apps have an increased incidence of sexually transmitted infections (STI) compared to self-identified HIV-negative, MSM attendees who met sexual partners via in-person venues, such as bars or clubs or through MSM-specific hook-up websites. Data were collected between August 2011 and January 2013 on all self-identified HIV-negative, MSM clients visiting the L.A. Gay & Lesbian Center for STI screening. A total of 7184 individuals tested for STIs and self-reported behaviours on drug use and social networking methods to meet sexual partners. Multivariate logistic regression models were used to analyse the results. Individuals who used GSN apps for meeting sexual partners had greater odds of testing positive for gonorrhoea (OR: 1.25; 95% CI 1.06 to 1.48) and for chlamydia (OR: 1.37; 95% CI 1.13 to 1.65) compared to individuals who met partners through in-person methods only. There were no significant differences in syphilis and HIV incidence between those who met partners via in-person venues only, on the internet or through GSN apps. The present study concludes that sexual health clinic MSM attendees who are meeting on GSN apps are at greater risk for gonorrhoea and chlamydia than MSM attendees who meet in-person or on the internet. Future interventions should explore the use of these novel technologies for testing promotion, prevention and education. Published by the BMJ Publishing Group Limited.
