    In the United States, racial disparities in HIV/AIDS are stark. Although African Americans comprise an estimated 14% of the U.S. population, they made up 52% of new HIV cases among adults and adolescents diagnosed in 2009. Heterosexual transmission is now the second leading cause of HIV in the United States. African Americans made up a full two-thirds of all heterosexually acquired HIV/AIDS cases between 2005 and 2008. Few demonstrated efficacious HIV prevention interventions designed specifically for adult, African-American heterosexual men exist. Here, we describe the process used to design a theory-based HIV prevention intervention to increase condom use, reduce concurrent partnering, and increase HIV testing among heterosexually active African-American men living in high HIV prevalence areas of New York City. The intervention integrated empowerment, social identity, and rational choices theories and focused on four major content areas: HIV/AIDS testing and education; condom skills training; key relational and behavioral turning points; and masculinity and fatherhood.

    In the United States, heterosexual transmission is the second leading cause of HIV/AIDS, and two-thirds of all heterosexually acquired cases diagnosed between 2005 and 2008 occurred among African-Americans. Few HIV prevention interventions have been designed specifically for African-American heterosexual men not seeking clinical treatment. Here we report results of a single-arm intervention trial of a theory-based HIV prevention intervention designed to increase condom use, reduce concurrent partnering and increase HIV testing among heterosexually active African-American men living in high HIV prevalence areas of New York City. We tested our hypothesis using McNemar discordant pairs exact test for binary variables and paired t-tests for continuous variables. We observed statistically significant declines in mean number of total and new female partners, unprotected sex partners, and partner concurrency in both primary and nonprimary sex partnerships between baseline and 3 months postintervention.

    When race and gender intersect, understanding gendered power may be complicated. The authors first describe the historical context that serves as important background for understanding gender and power in heterosexual African American relationships. Then they show how family solidarity in the face of social injustices often overrides gender equality as a goal for middle class African American couples with young children. The findings illustrate pragmatic equality within couple relationships and the willful suspension of gender roles for the well-being of the family as a whole. However, gendered power impacts couples in a variety of ways. Sometimes a woman's fear that the man might leave, for example, diminished her power in the relationship. Often a woman accommodated a man's greater power in the family because of her perception that he was often denied power in the larger society. Societal discrimination of women was less visible to couples. Implications for practice are provided.

    There are limited data on high-risk behaviors among heterosexual African American men with HIV infection. Risk behaviors were examined in a case-control study of HIV-infected (n = 90) and uninfected (n = 272) African American men who self-identified as heterosexual. Of men who self-identified as heterosexual, 31% (n = 28) of the infected men and 16% (n = 43) of the uninfected men reported having had anal sex with men. Among the heterosexual men reporting anal sex with men, 100% of the infected and 67% of the uninfected men reported inconsistent condom use during anal sex with men. Few of the infected (12%) and uninfected (2%) men reported oral sex with other men. Of the men who self-identified as heterosexual, 46% of those who were HIV-positive and 37% of those who were HIV-negative reported anal sex with women with infrequent condom use. An increasing risk for HIV was associated with decreasing age at first sexual experience (chi2, 9.3; p = .002). A history of injecting drugs (odds ratio [OR], 3.1; 95% confidence intervals [CIs], 1.8, 5.4) and amphetamine (OR, 4.3; 95% CIs, 1.1, 16.7) and methamphetamine (OR, 2.9; 95% CIs, 1.4, 6.3) use were associated with HIV. Innovative HIV prevention strategies are needed that move beyond the traditional gay versus straight model to effectively access hard-to-reach African American men who self-identify as heterosexual.

    Trichomonas vaginalis is the most prevalent curable STI worldwide and has been associated with adverse health outcomes and increased HIV-1 transmission risk. We conducted a cross-sectional analysis among couples to assess how characteristics of both individuals in sexual partnerships are associated with the prevalence of male and female T. vaginalis infection. African HIV-1 serodiscordant heterosexual couples were concurrently tested for trichomoniasis at enrolment into two clinical trials. T. vaginalis testing was by nucleic acid amplification or culture methods. Using Poisson regression with robust standard errors, we identified characteristics associated with trichomoniasis. Among 7531 couples tested for trichomoniasis, 981 (13%) couples contained at least one infected partner. The prevalence was 11% (n=857) among women and 4% (n=319) among men, and most infected individuals did not experience signs or symptoms of T. vaginalis . Exploring concordance of T. vaginalis status within sexual partnerships, we observed that 61% (195/319) of T. vaginalis -positive men and 23% (195/857) of T. vaginalis -positive women had a concurrently infected partner. In multivariable analysis, having a T. vaginalis -positive partner was the strongest predictor of infection for women (relative risk (RR) 4.70, 95% CI 4.10 to 5.38) and men (RR 10.09, 95% CI 7.92 to 12.85). For women, having outside sex partners, gonorrhoea, and intermediate or high Nugent scores for bacterial vaginosis were associated with increased risk of trichomoniasis, whereas age 45 years and above, being married, having children and injectable contraceptive use were associated with reduced trichomoniasis risk. Additionally, women whose male partners were circumcised, had more education or earned income had lower risk of trichomoniasis. We found that within African HIV-1 serodiscordant heterosexual couples, the prevalence of trichomoniasis was high among partners of T. vaginalis -infected individuals, suggesting

    Relationships and constructions of masculinity are central to understanding the process of male HIV disclosure, which is an important step towards accessing HIV-related services. Data from in-depth interviews and focus-group discussions with 23 HIV-positive, self-identified heterosexual, Black South African men were used to explore the disclosure process and how this process was negotiated in the context of constructions of masculinity. Of these men, 20 had disclosed to one or more persons, with partners and siblings being the preferred confidants. Disclosure was dependent on the acceptance of HIV status, perceived support and healthy relationships with others, HIV counselling and participation in educational and training activities. Non-disclosure was explained as a result of stigma, fear of rejection, discrimination, a lack of healthy relationships with others and lack of access to suitable disclosure strategies. Negative perceptions of HIV and hegemonic conceptions of masculinity hindered men from disclosing and seeking health services. Many men, however, managed to renegotiate their masculine identities to become responsible, knowledgeable HIV-positive individuals, protecting their families and becoming community educators. Findings suggest the need to consider gendered, contextual, skills-building/income-generating and guided interventions to promote male HIV disclosure and service uptake.

    Full Text Available Abstract Background African-American women are disproportionately affected by HIV, accounting for 60% of all cases among women in the United States. Although their race is not a precursor for HIV, the socioeconomic and cultural disparities associated with being African American may increase their risk of infection. Prior research has shown that interventions designed to reduce HIV infection among African-American women must address the life demands and social problems they encounter. The present study used a qualitative exploratory design to elicit information about strategies to prevent HIV transmission among young, low-income African-American women. Methods Twenty five low income African American women, ages 18–29, participated in five focus groups of five women each conducted at a housing project in Houston, Texas, a large demographically diverse metropolitan area that is regarded as one of the HIV/AIDS epicenters in the United States. Each group was audiotaped, transcribed, and analyzed using theme and domain analysis. Results The participants revealed that they had most frequently placed themselves at risk for HIV infection through drugs and drinking and they also reported drug and alcohol use as important barriers to practicing safer sex. The women also reported that the need for money and having sex for money to buy food or drugs had placed them at risk for HIV transmission. About one-third of the participants stated that a barrier to their practicing safe sex was their belief that there was no risk based on their being in a monogamous relationship and feeling no need to use protection, but later learning that their mate was unfaithful. Other reasons given were lack of concern, being unprepared, partner's refusal to use a condom, and lack of money to buy condoms. Finally, the women stated that they were motivated to practice safe sex because of fear of contracting sexually transmitted diseases and HIV, desire not to become pregnant, and

    Little research has been performed on how people respond to different strategies to negotiate condom use in sexual situations, and whether certain strategies tend to be perceived as more or less effective in condom use negotiation. This study examined gender differences and preferences in the use of and response to six different styles of condom use negotiation with a hypothetical sexual partner of the opposite gender. Participants were 51 heterosexually-active African-American men and women between the ages of 18 and 35, attending an inner-city community center. Study participants completed a semi-structured qualitative interview in which they were presented with six negotiation strategies —coercive, reward, legitimate, expert, referent, and informational--based on Raven’s 1992 Power/Interaction Model of Interpersonal Influence. Results showed that women participants responded best to referent, reward, and legitimate strategies, and worst to informational tactics. Men participants responded best to reward strategies, and worst to coercion to use condoms. Further, responses given by a subset of both women—and, to a greater extent, men--indicated that use of negotiation tactics involving coercion to use condoms may result in negative or angry reactions. Finally, response to strategies may vary with the value of the relationship as viewed by the target of negotiation. Implications for HIV prevention programs and media campaigns are discussed.

    Intimate partner violence directed at women by men continues to be a global concern. However, little is known about the factors associated with perpetrating intimate partner violence among heterosexual men. History of childhood sexual abuse and other sociodemographic variables were examined as potential factors associated with severe intimate partner violence perpetration toward women in a sample of heterosexual men in South Africa. Longitudinal logistic generalized estimating equations examined associations of childhood sexual abuse and sociodemographic variables at baseline with intimate partner violence perpetration at subsequent time points. Among participants with a steady female partner, 21.81 % (190/ 871) reported perpetrating intimate partner violence in the past year at baseline. Having a history of childhood sexual abuse (p sexual impulses in order to use a condom (p = .006) at baseline were associated with self-reported intimate partner violence perpetration in the past year at subsequent time points. With high levels of recent severe physical and/or sexual intimate partner violence perpetration in South Africa, comprehensive interventions are urgently needed. To more fully address gender-based violence, it is important to address associated factors, including exposure to childhood sexual abuse that could impact behavior later in life and that have long-lasting and deleterious effects on men and their female partners.

    To provide further evidence for the heterosexual transmission of the acquired immunodeficiency syndrome (AIDS) in Greece we examined 53 Greek female steady heterosexual partners of 53 anti-HIV-positive men. Human immunodeficiency virus (HIV) transmission was estimated by the detection of anti-HIV antibodies. Our results showed that 27.8% (5 of 18) of the female partners of bisexuals, 33.3% (2 of 6) of intravenous drug abusers (IVDA), and 100% (4 of 4) of those who had lived for a long time in Africa were found anti-HIV positive. In contrast, only 4% (1 of 25) of the studied sexual partners of hemophiliac carriers were found to be HIV seropositive. The use of condoms seemed to be the most important factor in reducing HIV transmission. According to our results the duration of sexual relationships and the practice of anal intercourse did not increase the possibility of seroconversion. These results confirm the heterosexual transmission of HIV. However, further studies should be conducted to evaluate the relative role of various risk factors and the overall importance of heterosexual spread of HIV infections.

    Background Effective contraception reduces unintended pregnancies and is a central strategy to reduce vertical HIV-1 transmission for HIV-1 infected women. Methods Among 2269 HIV-1 seropositive and 1085 seronegative women from 7 African countries who were members of HIV-1 serodiscordant heterosexual partnerships and who were participating in an HIV-1 prevention clinical trial, we assessed pregnancy incidence for women using various contraceptive methods using multivariate Andersen-Gill analysis. Results Compared with women using no contraceptive method, pregnancy incidence was significantly reduced among HIV-1 seropositive and seronegative women using injectable contraception (adjusted hazard ratio (aHR) 0.24, p=0.001 and aHR 0.25, ppregnancy risk only among HIV-1 seropositive women (aHR 0.51, p=0.004) but not seronegative women (aHR 0.64, p=0.3), and, for both seropositive and seronegative women, oral contraceptive pill users were more likely to become pregnant than injectable contraceptive users (aHR 2.22, p=0.01 for HIV-1 seropositive women and aHR 2.65, p=0.09 for HIV-1 seronegative women). Condoms, when reported as being used as the primary contraceptive method, marginally reduced pregnancy incidence (aHR 0.85, p=0.1 for seropositive women and aHR 0.67, p=0.02 for seronegative women). There were no pregnancies among women using intrauterine devices, implantable methods or who had undergone surgical sterilization, although these methods were used relatively infrequently. Conclusions Family planning programs and HIV-1 prevention trials need innovative ways to motivate uptake and sustained use of longer acting, less user-dependent contraception for women who do not desire pregnancy.

  17. Youth masculinities: compelling male heterosexuality.

    Richardson, Diane

    2010-12-01

    This article seeks to extend understandings of heterosexual masculine identities through an examination of young men's constructions of what motivates young men to engage in heterosexual practices and relationships, and what not having sex might mean for them. Using the masculinity literature and work on heterosexuality to frame the discussion and to contextualize the findings, it explores the complex dynamics that frame the relationship between masculinity and heterosexuality. Specifically, how dominant or 'hegemonic' discourses of heterosexuality shape young men's identities, beliefs and behaviour. It considers these questions using empirical data from a qualitative study of young people living in close-knit working-class communities in the North East of England, with a specific focus on cultural and social attitudes towards sexuality and sexual practices. Peer group networks are a key site for the construction and (re)production of masculinity and, therefore, an important arena within which gendered social approval and acceptance is both sought and gained. In this article, I explore the reasons why young men engage in specific types of heterosexual practice in order to gain social approval. A central question is the extent to which heterosexuality is compelling for young men. That young men do feel compelled to behave in certain ways sexually, behaviours that they may be uncomfortable with and/or dislike, and the fact that they feel they are restricted in terms of how they can talk about their experiences within their peer group networks, demonstrates the power of dominant discourses of masculinity in everyday life. This is addressed through an examination of the restrictive effects of normative discourses about male heterosexuality, including their privatizing effects, which suggest that youth masculinities are often experienced in ways that are highly contradictory requiring young men to adopt a range of strategies to deal with this.

    The AIDS epidemic has spread rapidly in Africa among the urban impoverished where multiple sexual partners and sexually transmitted diseases are common. Over 80% of the 9 million Africans who will develop AIDS before the year 2000 will have been contaminated sexually. Poverty, multiple sexual partners in the framework of prostitution, and drug addiction are responsible for rapid spread of HIV infection in Southeast Asia, the West India, and Brazil. Drug addiction has played a major role in diffusion of HIV into the general population of Europe and the US. Prevalence rates are much higher in sexually transmitted disease centers in France and the US than among blood donors or pregnant women. Sexually transmitted diseases and heterosexual transmission have been studied in Africas since diagnostic tests became available. Several studies, the majority conducted among prostitutes in Nairobi or Kinshasa and their clients, allow establishment of a list of sexually transmitted diseases associated with increased risk of seroconversion. Genital ulcers within the past 6 months presented a relative risk of 2-4 depending on the series. Urethral or cervical gonorrhea has a lower relative risk of 1.2 in most studies. Absence of circumcision was also a risk factor. Studies were subsequently conducted in Europe on factors favoring sexual transmission. 513 heterosexual couples together for a minimum duration of 18 months and an average of 38 months were included in the Multicenter European Study conducted in 10 centers in 9 countries. The "index" subject was male in 400 cases and female in 113. At entry into the study, 73 of 400 males (18.2%) and 10 of 113 females (8.8%) had already infected their partners. Duration of union, frequency of intercourse, mode of transmission of the index subject, and oral contraceptive use had no effect on risk of transmission. Factors increasing risk of infection included the severity of immunosuppression of the index subject, whether judged by

    Phylogenetic studies show links between heterosexual women and men who have sex with men (MSM) that are more numerous than from heterosexual men to women suggesting that HIV infections among heterosexual women may stem from MSM. Poor communities have been associated with high rates of HIV among heterosexual women. Our analysis investigates potential transmission of HIV between MSM and female heterosexuals. National HIV Behavioral Surveillance data describe transmission risk behaviors of MSM, and HIV case reporting data describe the percentages of cases that are attributed to transmission risk categories. We examined correlations between the percentages of men who were MSM who also have sex with women and female heterosexual cases. We also examined census data to characterize each city in terms of poverty level and race/ethnicity makeup. There was a high correlation (0.93) between the percentage of reported living HIV cases attributed to male heterosexual contact and female heterosexual contact and a moderate nonsignificant correlation (0.49) between the percentage of MSM who were men who have sex with men and women (MSMW) in National HIV Behavioral Surveillance and the percentage of reported cases that were attributed to female heterosexual contact suggesting some potential overlap. Cities with high levels of poverty and African American/Black residents had higher levels of MSMW and higher levels of heterosexual female cases. Addressing HIV in cities with high levels of MSMW may have the dual effect of improving the health of MSM populations that have a high burden of HIV and to improve the health of their larger communities.

    Herpes zoster (HZ) is caused by VZV reactivation that is facilitated by a declined immunity against varicella-zoster virus (VZV), but also occurs in immunocompetent individuals. Cytomegalovirus (CMV) infection is associated with immunosenescence meaning that VZV-specific T-cells could be less responsive. This study aimed to determine whether CMV infection could be a risk factor for the development of HZ. CMV IgG serostatus was determined in stored serum samples from previously prospectively recruited ambulatory adult HZ patients in the UK (N = 223) in order to compare the results with those from UK population samples (N = 1545) by means of a logistic regression (controlling for age and gender). Furthermore, we compared the UK population CMV seroprevalence with those from population samples from other countries (from Belgium (N1 = 1741, N2 = 576), USA (N = 5572) and Australia (N = 2080)). Furthermore, CMV IgG titers could be compared between UK HZ patients and Belgium N2 population samples because the same experimental set-up for analysis was used. We found UK ambulatory HZ patients to have a higher CMV seroprevalence than UK population samples (OR 1.56 [1.11 2.19]). CMV IgG seropositivity was a significant risk factor for HZ in the UK (OR 3.06 [1.32 7.04]. Furthermore, high CMV IgG titers (exceeding the upper threshold) were less abundant in CMV-seropositive Belgian N2 population samples than in CMV-seropositive UK HZ patients (OR 0.51 [0.31 0.82]. We found CMV-seroprevalence to increase faster with age in the UK than in other countries (P < 0.05). We conclude that CMV IgG seropositivity is associated with HZ. This finding could add to the growing list of risk factors for HZ. PMID:25905443

    HIV seropositive individuals and their heterosexual partners/spouses, either seropositive or seronegative, are facing several mental health challenges. The objective of this study was to examine gender differences in depressive symptoms among HIV-positive concordant and HIV-discordant couples. We identified heterosexual couples from participants of a randomized controlled trial conducted in Anhui province, China. A total of 265 couples, comprising 129 HIV+ male/HIV- female couples, 98 HIV- male/HIV+ female couples, and 38 HIV-positive concordant couples, were included in the analyses. We collected data using the computer-assisted personal interview method. We used a linear mixed-effects regression model to assess whether gender differences in depressive symptoms varied across couple types. HIV-positive women reported a significantly higher level of depressive symptoms than their partners/spouses. HIV-positive women with HIV-positive partners had higher depressive symptoms than those with HIV-negative partners, whereas HIV-positive men reported similar levels of depressive symptoms regardless of their partners' serostatus. Among the concordant couples, those with the highest annual family income showed the greatest gender differences in depressive symptoms. We suggest that family interventions should be gender- and couple-type specific and that mental health counseling is warranted not only for HIV-positive women but also for HIV-negative women in an HIV-affected relationship.

    Full Text Available We can assume without fail that the psychosocial implications in case of HIV/AIDS are as overwhelming as the medical aspects. For the positive person as well as for those who assist the seropositive people, the uncertainty frames the medical prognosis. All the effects that occur are entirely funded: the loss of self-trust as well as mistrusting others, stigmatization, isolation, getting abandoned by the family, friends, neighbors and school mates or coworkers. The current study aims to evaluate this aspect, the fact that the living environment of the seropositive person does not lead to significant differences as far as adjusting to HIV/AIDS diagnosis is concerned, but the adjusting differences are more related to the personality structure of the infected person, to the way this person identifies strategies of coping with the new situations he / she has to deal with (cognitive, emotional and behavioral strategies. In the applicative part of the study, we analyze the adjustment to the diagnosis, as well as the adherence to the treatment, by applying certain specific work instruments.

    A brief review of the literature concerning familial transvestism is given. The case history of father-son heterosexual transvestism is presented. The son appears to have been ignorant of his father's transvestism. Early childhood experiences as an aetiological factor seem inadequate to explain the similarities of the two subjects' transvestite behaviour. It is suggested that constitutional factors play a part in the aetiology of heterosexual transvestism.

    Background Understanding and addressing heterosexual HIV transmission requires attention to the range and context of heterosexual sexual behaviors. We sought to determine population-based prevalence of condomless anal intercourse (CAI) among individuals at increased heterosexual HIV risk in Baltimore and to identify demographic, behavioral, and health related correlates. Methods Data were from a cross-sectional study of 185 males and 198 females at increased heterosexual risk for HIV recruited using respondent driven sampling as part of CDC's National HIV Behavioral Surveillance Project in Baltimore, August-December 2010. Bivariate and multivariate logistic regression examined factors associated with heterosexual CAI. Results The sample was majority African-American, with mean age of 38 among men and 34 among women. Forty-two percent of men (95% C.I.: 30.9, 52.0%) and 38% of women (95% C.I.: 29.4, 47.2%) reported any CAI in the past year, with variance by partner type and gender. Among men, CAI was significantly associated with homelessness, casual and exchange partners, same sex partner in past year, and substance use. Among women, CAI was significantly associated with lower education, casual and exchange partners, same sex partner in past year, multiple partners, and substance use. In adjusted gender-specific models, males and females with increasing numbers of partners were more likely to engage in CAI. Conclusions It is important to recognize the efficiency of transmission of HIV and other STIs through CAI. There is a need to broaden heterosexual sexual health promotion and HIV/STI prevention to adequately and appropriately address risks and prevention strategies for anal intercourse. PMID:25970308

  9. The consequences of the heterosexual norm

    Full Text Available Librarians may exclude people accidentally. This is so because there is a widespread use of classifications and subject headings reflecting the heterosexual norm. Critical classification theory tackles this norm for the reason that it affects the retrieval of gay literature. In order to allow a reconsideration of this exclusive practice in the LIS community I challenge two main questions: Firstly, how does the heterosexual norm appear in classification systems and subject headings lists? And secondly, what are the consequences of that practice for the retrieval of gay literature?This paper focuses on the professional practise in Swedish public libraries. If subject cataloguing prevents Lesbians, Gays, Bisexuals and Transgender (LGBT finding their literatures, then Swedish public libraries are upholders of the exclusive heterosexual norm in society.

    Objective: The knowledge on Helicobacter pylori (H. pylori) contribution in the pathology of the liver and biliary tract diseases in human is very limited. The aim of this study was to assess the probable association between H. pylori seropositivity and hepatic encephalopathy. Methodology: This is a case control study conducted through three groups, cirrhotics with hepatic encephalopathy (HE), cirrhotics without HE and healthy controls. All subjects were examined serologically for determination of IgG class antibodies to H. pylori based on ELISA technique. Results: H. pylori seropositivity was present in 88% cirrhotic patients with hepatic encephalopathy, 86% cirrhotics without hepatic encephalopathy and 66% healthy controls. Conclusion: According to our results, H. pylori seropositivity rate in cirrhotic patients with or without hepatic encephalopathy was higher than healthy controls. But H. pylori seropositivity rate was not significantly different among cirrhotics with hepatic encephalopathy and those without it.

    Non-heterosexual young women have a higher rate of unintended pregnancy than their heterosexual peers, but their fertility behaviors are understudied. We use longitudinal data from the Relationship Dynamics and Social Life study to investigate mechanisms contributing to non-heterosexual women's higher pregnancy risk. These data include weekly reports of relationships, sex, and contraceptive use over 30 months. We compare the relationships and fertility behaviors of three groups: exclusively heterosexual (consistent heterosexual behavior, identity, and attraction); mostly heterosexual (heterosexual identity with same-sex behavior and/or same-sex attraction); and LGBTQ (any non-heterosexual identity). We find that mostly heterosexual and LGBTQ women behave differently from exclusively heterosexual women in ways likely to elevate their risk of unintended pregnancy: more distinct partners during the study period, more sexual intercourse with men, less frequent contraceptive use, less use of a dual method (condom plus hormonal method), and more gaps in contraceptive coverage. Mostly heterosexual women resemble LGBTQ women in their contraceptive behavior but have significantly more intercourse with men, which may increase their pregnancy risk relative to both LGBTQ and exclusively heterosexual women. We conclude by considering implications for LGBTQ health and the measurement of sexual minority populations.

    2012-12-01

    Full Text Available The study analyzes the conceptions of heterosexuality of Psychology students at Universidad Nacional de Córdoba, and explores its associations with attitudes towards homosexuality. An exploratory research design was conducted, mixing qualitative and quantitative approaches, with a non probabilistic sample, 89 students (64 of the initial section of the career and 25 of the final section. Students answered a written self-report about the question: "Heterosexuality, is it natural? Why?". Seven types of conceptions of heterosexuality were identified, four of them based on essentialists views, and three presented socio-constructionist arguments. Data suggests an association between negative attitudes toward homosexuals and essentialists conceptions of heterosexuality, especially in lower grades students. This study generated questions and reflections about future therapist sexualities and gender-blind training.

    Full Text Available Abstract Despite multiple sexual exposure to HIV-1 virus, some individuals remain HIV-1 seronegative (exposed seronegative, ESN. The mechanisms underlying this resistance remain still unclear, although a multifactorial pathogenesis can be hypothesised. Although several genetic factors have been related to HIV-1 resistance, the homozigosity for a mutation in CCR5 gene (the 32 bp deletion, i.e. CCR5-Delta32 allele is presently considered the most relevant one. In the present study we analysed the genotype at CCR5 locus of 30 Italian ESN individuals (case group who referred multiple unprotected heterosexual intercourse with HIV-1 seropositive partner(s, for at least two years. One hundred and twenty HIV-1 infected patients and 120 individuals representative of the general population were included as control groups. Twenty percent of ESN individuals had heterozygous CCR5-Delta 32 genotype, compared to 7.5% of HIV-1 seropositive and 10% of individuals from the general population, respectively. None of the analysed individuals had CCR5-Delta 32 homozygous genotype. Sequence analysis of the entire open reading frame of CCR5 was performed in all ESN subjects and no polymorphisms or mutations were identified. Moreover, we determined the distribution of C77G variant in CD45 gene, which has been previously related to HIV-1 infection susceptibility. The frequency of the C77G variant showed no significant difference between ESN subjects and the two control groups. In conclusion, our data show a significantly higher frequency of CCR5-Delta 32 heterozygous genotype (p = 0.04 among the Italian heterosexual ESN individuals compared to HIV-1 seropositive patients, suggesting a partial protective role of CCR5-Delta 32 heterozygosity in this cohort.

    Sport is a social institution that perpetuates gendered ideologies in the wider society through appealing to discourses of the naturalness of men's privilege and domination in society. Heteronormativity regulates the roles, behaviours, appearances and sexualities of, and relationships between and among, women and men. Moreover, heteronormative discourses normalise a particular relationship between sex, gender and sexuality that posits woman/feminine/heterosexual (and man/masculine/heterosexual) as a natural order from which variance is considered a punishable deviance. This paper outlines the effects of heteronormative discourses in the lives of women footballers in South Africa, through drawing on interviews with a wide range of women footballers. The paper shows how heteronormative discourses nurture homophobic attitudes that serve to regulate the appearances and performances of South African women.

    Full Text Available Abstract Background There is paucity of published data on human immunodeficiency virus (HIV seroprevalence among migrant workers entering Middle-East particularly Kuwait. We took advantage of the routine screening of migrants for HIV infection, upon arrival in Kuwait from the areas with high HIV prevalence, to 1 estimate the HIV seroprevalence among migrant workers entering Kuwait and to 2 ascertain if any significant time trend or changes had occurred in HIV seroprevalence among these migrants over the study period. Methods The monthly aggregates of daily number of migrant workers tested and number of HIV seropositive were used to generate the monthly series of proportions of HIV seropositive (per 100,000 migrants over a period of 120 months from January 1, 1997 to December 31, 2006. We carried out spectral analysis of these time series data on monthly proportions (per 100,000 of HIV seropositive migrants. Results Overall HIV seroprevalence (per 100,000 among the migrants was 21 (494/2328582 (95% CI: 19 -23, ranging from 11 (95% CI: 8 – 16 in 2003 to 31 (95% CI: 24 -41 in 1998. There was no discernable pattern in the year-specific proportions of HIV seropositive migrants up to 2003; in subsequent years there was a slight but consistent increase in the proportions of HIV seropositive migrants. However, the Mann-Kendall test showed non-significant (P = 0.741 trend in de-seasonalized data series of proportions of HIV seropositive migrants. The spectral density had a statistically significant (P = 0.03 peak located at a frequency (radians 2.4, which corresponds to a regular cycle of three-month duration in this study. Auto-correlation function did not show any significant seasonality (correlation coefficient at lag 12 = – 0.025, P = 0.575. Conclusion During the study period, overall a low HIV seroprevalence (0.021% was recorded. Towards the end of the study, a slight but non-significant upward trend in the proportions of HIV seropositive

    Negative attitudes of heterosexual people toward same-sex marriage relate to the degree to which they are homophobic. However, it has been understudied whether there exists a gender difference in this association. Our results indicated that homophobia was the best predictor of attitudes toward gay male and lesbian marriage, and this was equally true for both heterosexual men and women. However, the attitudinal difference between gay male and lesbian marriage was related to homophobia in men but not in women. That is, for men only, being less homophobic towards lesbians than towards gay men was associated with favoring lesbian over gay men marriage. Considering these results, the role of gender in attitudes toward same-sex marriage seems to be as an important moderator of homophobia. PMID:20390996

    Long since it have been suggested that a subpopulation of patients with rheumatoid arthritis (RA), diagnosed with negative rheumatoid factor (RF) tests, represents a clinical entity quite distinct from that of seropositive rheumatoid arthritis. The aim of the study was to establish a scientific comparative analysis between RA seronegative and seropositive, regarding course and prognoses of the disease. Two hundred fifty patients with rheumatoid arthritis according to the (American College of Rheumatology) criteria were retrospectively studied by analysis the course and prognoses of disease. All examinees were between 25-60 years of age (Xb=49.9, SD=10.3) with disease duration between 1-27 years (Xbox=6.41, SD=6.47). Course of the disease with "remissions and exacerbations", progressive continual course and bad prognoses, were more presented in seropositive group ofpatients. Partial remission was more common in seronegative patients but according to serostatus and gender has not shown statistically significant difference. Duration of the disease was a specific prognostic sign for both subsets [(r=0.32, p0.05) seronegative, (r=0.18, p<0.05) seropositive]. Seropositive and seronegative RA distinguish in course and prognostic feature, but not enough to differentiate them in two different forms of the disease. Regarding the sero-status, differences within sex, with some exceptions, are not relevant.

    Full Text Available Lung cancer is the leading cause of cancer mortality worldwide. Helicobacter pylori (H. pylori is a risk factor for distal stomach cancer, and a few small studies have suggested that H. pylori may be a potential risk factor for lung cancer. To test this hypothesis, we conducted a study of 350 lung adenocarcinoma cases, 350 squamous cell carcinoma cases, and 700 controls nested within the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study (ATBC cohort of male Finnish smokers. Controls were one-to-one matched by age and date of baseline serum draw. Using enzyme-linked immunosorbent assays to detect immunoglobulin G antibodies against H. pylori whole-cell and cytotoxin-associated gene (CagA antigens, we calculated odds ratios (ORs and 95% confidence intervals (95% CIs for associations between H. pylori seropositivity and lung cancer risk using conditional logistic regression. H. pylori seropositivity was detected in 79.7% of cases and 78.5% of controls. After adjusting for pack-years and cigarettes smoked per day, H. pylori seropositivity was not associated with either adenocarcinoma (OR: 1.1, 95% CI: 0.75-1.6 or squamous cell carcinoma (OR: 1.1, 95% CI: 0.77-1.7. Results were similar for CagA-negative and CagA-positive H. pylori seropositivity. Despite earlier small studies suggesting that H. pylori may contribute to lung carcinogenesis, H. pylori seropositivity does not appear to be associated with lung cancer.

    Chagas disease is an important health problem in Latin America due to its incapacitating effects and associated mortality. Studies on seropositivity for Trypanosoma cruzi in Mexican dogs have demonstrated a direct correlation between seropositivity in humans and dogs, which can act as sentinels for the disease in this region. The objective of this study was to determine the seropositivity for T.cruzi infection in dogs from Sonora, a northern borderstate of Mexico. Responsible pet owners were selected at random from an urban area of Empalme municipality, Sonora, Mexico, and from there, 180 dog samples were collected. Anti-T. cruzi antibodies were determined using the enzyme-linked immunosorbent assay (ELISA) method. Reactive ELISA sera were processed by indirect immunofluorescence to confirm the presence of anti-T. cruzi antibodies. For the statistical analysis, chi-square tests were conducted. Dogs' sera showed a seropositivity rate of 4.44%. The rate of seropositivity was not associated with the dogs' age, sex, or socioeconomics pertaining to the geographical area. One sample (1/180, 0.55%) showed the acute state of the disease. The study found a presence of anti-T. cruzi antibodies in dogs in this area, which suggests vector transmission. There is a need for active surveillance programs throughout the state of Sonora and vector control strategies should also be implemented in endemic regions.

    This study tested whether male sexual orientation and gender nonconformity influenced functional cerebral lateralization for the processing of facial emotions. We also tested for the effects of sex of poser and emotion displayed on putative differences. Thirty heterosexual men, 30 heterosexual women, and 40 gay men completed measures of demographic variables, recalled childhood gender nonconformity (CGN), IQ, and the Chimeric Faces Test (CFT). The CFT depicts vertically split chimeric faces, formed with one half showing a neutral expression and the other half showing an emotional expression and performance is measured using a "laterality quotient" (LQ) score. We found that heterosexual men were significantly more right-lateralized when viewing female faces compared to heterosexual women and gay men, who did not differ significantly from each other. Heterosexual women and gay men were more left-lateralized for processing female faces. There were no significant group differences in lateralization for male faces. These results remained when controlling for age and IQ scores. There was no significant effect of CGN on LQ scores. These data suggest that gay men are feminized in some aspects of functional cerebral lateralization for facial emotion. The results were discussed in relation to the selectivity of functional lateralization and putative brain mechanisms underlying sexual attraction towards opposite-sex and same-sex targets.

    This article addresses heterosexual men's familiarity with the female condom and their attitudes toward this barrier method. Qualitative interviews were conducted with 71 ethnically diverse and heterosexually active men who were recruited in sexually transmitted disease (STD) clinics or through word of mouth in communities with high HIV/STD seroprevalence in New York City during fall 1994 to fall 1995. Only one man reported previous experience with the female condom. The large majority of men had no or limited knowledge of the female condom. Men's reactions to learning about this method ranged from positive to negative, although most men reported willingness to have sex with a partner who wanted to use the female condom. Positive reactions included: endorsement of a woman-controlled condom and her right to use it, the potential for enhancing one's sexual pleasure, and an eagerness to have a new sexual experience. Negative reactions centered on the "strangeness" and "bigness" of the female condom, concerns about prevention efficacy, and concerns about reductions in sexual pleasure. Our findings highlight the need for HIV prevention programs that target heterosexual men and promote the use of the female condom.

The aim of the study is the investigation and comparison of frequency and type of extra-articular manifestations in a well defined community based cohort of patients with seropositive and seronegative rheumatoid arthritis. Using the ACR (1987 criteria for rheumatoid arthritis, patients have been classified into the 2nd and 3rd functional class (ARA. The studied group consisted of 125 seronegative patients with titters lower than 1:64 as defined by Rose-Waaler test, whereas the control group consisted of 125 seropositive patients with titters of 1:64 or higher.

    This cross-sectional study among heterosexual migrant groups in south-eastern Amsterdam, the city area where the largest migrant groups live, provides an insight into HIV testing behaviour in this particular group. Participants were recruited at street locations (May 1997-July 1998) and interviewed using structured questionnaires. They also donated saliva for HIV testing. In total, 705 males and 769 females were included in this study (Afro-Surinamese (45%), Dutch-Antilleans (15%) and West Africans (40%)). Prior HIV testing was reported by 38% of all migrants (556/1479), of which only a minority (28%) had actively requested HIV testing. Multivariate logistic regression showed that not actively requesting HIV testing was more likely among younger (migrants, especially women (ORwomen: 4.79, p risk should be facilitated by promoting HIV testing and by improving accurate self-assessment of risk for HIV infection, especially among the groups that do not actively request HIV testing. This would increase HIV awareness and provide the opportunity of better medical care earlier in HIV infection.

    Although there has been considerable research investigating the ability to identify sexual orientation from static images, or "gaydar," few studies have considered the role of female sexual orientation or sexual interest (for example, sociosexual orientation) in judgment accuracy. In two studies, we investigated the sexuality detection ability, and masculinity and femininity as cues used in judgment. In Study 1, we recruited heterosexual (N = 55) and homosexual (N = 71) women to rate the sexual orientation of homosexual and heterosexual male and female targets (N = 80: 20 heterosexual men, 20 homosexual men, 20 heterosexual women, and 20 homosexual women). We found that detection accuracy was better than chance levels for both male and female targets and that male targets were more likely to be falsely labeled as homosexual than female targets were. Overall, female faces were more accurately identified as heterosexual or homosexual than male faces and homosexual female raters were biased towards labeling targets as homosexual. Sociosexuality did not influence the accuracy with which targets were identified as heterosexual or homosexual. In Study 2, 100 heterosexual and 20 homosexual women rated the stimulus for masculinity and femininity. Heterosexual women were rated as more feminine and less masculine than homosexual women and homosexual men were rated as more feminine and less masculine than heterosexual men. Sexual orientation of the judges did not affect the ratings. The results were discussed with a reference to evolutionary and cultural influences affecting sexual orientation judgment accuracy.

    Gabriel Westman

    Full Text Available Alzheimer's disease (AD has been associated with increased local inflammation in the affected brain regions, and in some studies also with elevated levels of proinflammatory cytokines in peripheral blood. Cytomegalovirus (CMV is known to promote a more effector-oriented phenotype in the T-cell compartment, increasing with age. The aim of this study was to investigate the inflammatory response of peripheral blood mononuclear cells (PBMCs from AD patients and non-demented (ND controls. Using a multiplex Luminex xMAP assay targeting GM-CSF, IFN-γ, IL-1β, IL-2, IL-4, IL-5, IL-6, IL-8, IP-10 and TNF-α, cytokine profiles from PBMCs were analysed after stimulation with anti-CD3/CD28 beads, CMV pp65 peptide mix or amyloid β (Aβ protofibrils, respectively. CMV seropositive AD subjects presented with higher IFN-γ levels after anti-CD3/CD28 and CMV pp65 but not after Aβ stimulation, compared to CMV seropositive ND controls. When analysing IFN-γ response to anti-CD3/CD28 stimulation on a subgroup level, CMV seropositive AD subjects presented with higher levels compared to both CMV seronegative AD and CMV seropositive ND subjects. Taken together, our data from patients with clinically manifest AD suggest a possible role of CMV as an inflammatory promoter in AD immunology. Further studies of AD patients at earlier stages of disease, could provide better insight into the pathophysiology.

    Bovine neosporosis is caused by the protozoan Neospora caninum and is one of the major causes of abortion in cows. Cattle are intermediate hosts of this parasite and may have asymptomatic or symptomatic infections. Therefore, the aim of this study was to evaluate oxidative stress marker reactive oxygen species (ROS), thiobarbituric reactive acid substances (TBARS) levels, glutathione S-transferase (GST), adenosine deaminase (ADA), and butyrylcholinesterase (BChE) activities in dairy cows seropositives for N. caninum (asymptomatic or symptomatic). Dairy cows (n=90) were tested by immunofluorescent antibody assay (IFA) for N. caninum and divided accordingly into three groups: the group A (seronegatives, n=30), the group B (seropositives and asymptomatic, n=30), and the group C (seropositives and symptomatic, n=30). It was observed increased levels of TBARS and reduced (Pcows (the group C) compared to seronegatives dairy cows (the group A). Based on these results, it was observed that seropositive animals showed cell damage associated with oxidative stress and inflammation, mainly in those with symptomatic infections. Increased seric ROS levels and BChE activity may have influenced N. caninum pathogenesis in symptomatic animals due to increased cell damage and exacerbated inflammatory response, leading to the development of clinical signs.

    Responses of 33 homosexual (gay) fathers were compared with those of 33 heterosexual (nongay) fathers on the Iowa Parent Behavior Inventory, an empirical measure of dimensions of parenting behavior. Gay fathers did not differ significantly from nongay fathers in their reported degree of involvement nor in intimacy level with children. Gay fathers tended to be more strict, more responsive to children's needs, and to provide reasons for appropriate behavior to children more consistently than nongay fathers. Several explanations are explored for these similarities and differences in parenting styles.

    In recent years, social scientists have identified not just heterosexism and homophobia as social problems, but also heteronormativity--the mundane, everyday ways that heterosexuality is privileged and taken for granted as normal and natural. There is little empirical research, however, on how heterosexuality is reproduced and then normalized for…

    To determine prevalence of and risk factors associated with HIV and syphilis seropositivity and estimate incidence of HIV infection among Peruvian men who have sex with men (MSM) and characterize behaviors of men who report sex with both men and women ('bridgers'). Cross-sectional study of MSM in Lima, Peru. Four-hundred and fifty-one MSM (of whom 442 responded to the question regarding sexual orientation) recruited through street outreach. Each was interviewed and underwent serologic testing for syphilis and HIV, including the less sensitive enzyme immunoassay test to estimate HIV incidence. Overall, HIV and syphilis prevalence were 18.5% and 16.0%, respectively, with highest prevalence among cross-dressers (33.3% and 51.1%, respectively). The estimated overall HIV seroincidence was 11.2% per year (95% confidence interval, 4.8-23.6). Overall, 47.1% of men reported ever having sex with a woman: 78.6% of men self-identifying as heterosexuals, 85.1% of bisexuals, 35.5% of homosexuals, and 12.5% of cross-dressers. Of these, 26.5% were 'bridgers', of whom 55% reported two or more female partners during the last year. 'Bridgers' were less likely to have always used condoms during the past year for vaginal sex (17%) than for insertive anal sex with men (25.5%). Among MSM in Peru, HIV and syphilis prevalence and HIV incidence were high, especially among cross-dressers. The high prevalence of bisexuality and low rates of consistent condom use, especially with female sexual partners indicates potential HIV transmission into the heterosexual population.

    Leptospirosis is postulated as a possible cause of Mesoamerican Nephropathy (MeN) in Central American workers. Investigate job-specific Leptospira seroprevalence and its association with kidney disease biomarkers. In 282 sugarcane workers, 47 sugarcane applicants and 160 workers in other industries, we measured anti-leptospiral antibodies, serum creatinine, and urinary injury biomarkers, including neutrophil gelatinase-associated lipocalin (NGAL), interleukin-18 (IL-18), and N-acetyl-D-glucosaminidase (NAG). Leptospira seroprevalence differed among job categories and was highest among sugarcane cutters (59%). Seropositive sugarcane workers had higher NGAL concentrations (relative mean: 1.28; 95% CI: 0.94-1.75) compared to those who were seronegative, with similar findings among field and non-field workers. Leptospira seroprevalence varied by job category. There was some indication that seropositivity was associated with elevated biomarker levels, but results were inconsistent. Additional studies may help establish whether Leptospira infection plays any role in MeN among Central American workers.

    1989-01-01

    As part of a prospective longitudinal study of individuals who are human immunodeficiency virus (HIV) positive, cranial MR imaging was performed on 89 HIV-seropositive patients and correlated with clinical data. MR results were asymptomatics: MR images normal-58, abnormal-16; myelopathics: normal-seven, abnormal-four; encephalopathics: normal-three, abnormal-two. In asymptomatics, neurologic examination was positive in all with positive MR results but positive in only some with negative MR results. The authors concluded that MR imaging can show indirect evidence of HIV infection early in the disease, but abnormalities will be minor and seen only in the minority (21%) of symptomatics; these minor abnormalities may antedate clinical symptoms but not signs; an increase in severity of clinical disease correlates with increasingly severe atrophy and demyelination; and in some seropositives, whether asymptomatic or symptomatic, MR results remain normal

    Long since it have been suggested that a subpopulation of patients with rheumatoid arthritis, diagnosed with negative rheumatoid factor tests, represents a clinical entity quite distinct from that of seropositive rheumatoid arthritis (RA). Our aim was to establish a scientific comparative analysis between seronegative and seropositive rheumatoid arthritis, regarding some radiological and clinical parameters, applied for the first time on patients from Kosovo. Two hundred fifty patients with rheumatoid arthritis according to the American College of Rheumatology criteria were retrospectively studied by analysis the radiographic damage and clinical parameters of the disease, using a data base. All examinees were between 25-60 years of age (Xb=49.96, SD=10.37) with disease duration between 1-27 years (Xb = 6.41, SD=6.47). All patients underwent a standardised evaluation radiographs. Baseline standardised poster anterior radiographs of hands and feet and radiographs of other joints, depending on indications, were assessed. Erythrocyte sedimentation rate values correlated with the radiological damages and statistical difference was found for seronegative subset (r=0.24, p<0.01). Longer duration of the disease resulted in the increase of radiological changes in both subsets (r=0.66, p<0.01) seronegative, (r=0.49, p<0.01) seropositive. Anatomic changes of IInd and IIIrd level were nearly equally distributed in both subsets, 76 (60.8%) seronegative, 75 (60%) seropositive. Radiological damages are nearly equal in both subsets, elevate in relation to the duration of the disease and correlate with ESR values. Regarding the sero-status, differences within sex, with some exceptions, are not relevant. Although there are some definite quantitative and qualitative differences regarding sero-status, obviously there is a great deal of overlap between the two groups.

    This study was conducted on prisoners of Central Jail, Bahawalpur and on blood donors at Blood Bank Bahawal Victoria Hospital (BVD), Bahawalpur from 1st August 2005 to 30th November 2005. The intension was to study the sero prevalence of hepatitis Band C in prisoners and to note risk factor if any predisposing to the infection. All the prisoners of central jail Bahawalpur present during the study period, aged more than 18 years of either sex were included as the study group and a comparative group was blood donors presenting to blood bank BVH, Bahawalpur during this period. All the cases in study group (2086) as well as control group (9714) were screened for hepatitis B (HBs Ag) and hepatitis C (anti-HCV) infection detected on serum by One Step Test Device. All the positive cases were confirmed by Enzyme Linked Immunosorbent Assay. After an explanation, verbal consent was taken and a questionnaire was filled before taking samples from all the study group cases. On the basis of screening, prisoners were decided into seropositive group and sero-negative group. The different variable applied on both the groups were age, sex, occupation, residence, marital status, self shaving / by barber, family history of (H/o) jaundice, H/o blood trans-fusion, operation, tattooing and body piercing, drug abuse, same sex / extramarital sex and hepatitis B vaccination status. Total prisoners screened were 2086. Out of them 2072 were males (99.3%). Mean age was 34 years. Total seropositive cases were 249 (11.9%) While during the same period seropositivity in blood donors (control group) was 5.9%. Seropositivity of HBV was 5.6% in study group and 3.1% in control group (p<0.001), HCV was 6.3% Vs 2.8% (p<0.001), statistically very significant difference. Risk factors analysis among prisoners revealed that drug abuse was significantly associated with seropositivity (27% Vs 12%, p value <0.001). Among drug abusers, very high percentage of intravenous drug users was positive (89.2%, 25 out

    The purpose of this study was to develop a scale for assessing the attributes of the heterosexual love of alcoholics. Using the characteristics and categories related to the heterosexual love of alcoholics found in previous research, we created a "Heterosexual Love Assessment Scale for Alcoholics" and conducted a survey among 110 alcoholics (80 men and 30 women). The following three factors were extracted from the results: "mutual respect", "superficial intimacy", and "fear of being disliked", A high level of reliability was obtained on the scales indicated below (alpha = 63-82), and concurrent validity was confirmed between these and the Adult Attachment Scale (ECR: Experiences in Close Relationships inventory). Further, correlations were found between "mutual respect" and the benefit of heterosexual love in recovery, and between the other two factors and the impediment of heterosexual love, and between the Denial & Awareness Scale (for alcoholic). As this scale can be used to assess the type of heterosexual love of alcoholics, we predict that it will be useful in examining the effects of heterosexual love on recovery and as a tool for offering advice.

    Full Text Available Abstract Background The most efficient sexual behavior for HIV transmission is unprotected receptive anal intercourse. However, it is unclear what role heterosexual unprotected anal sex is playing in the world's worst HIV epidemics of southern Africa. The objective is to examine the prevalence of heterosexual unprotected anal intercourse among men and women who drink at informal alcohol serving establishments (shebeens in South Africa. Methods Cross-sectional surveys were collected from a convenience sample of 5037 patrons of 10 shebeens in a peri-urban township of Cape Town, South Africa. Analyses concentrated on establishing the rates of unprotected anal intercourse practiced by men and women as well as the factors associated with practicing anal intercourse. Results We found that 15% of men and 11% of women reported anal intercourse in the previous month, with 8% of men and 7% of women practicing any unprotected anal intercourse. Multiple logistic regression showed that younger age, having primary and casual sex partners, and meeting sex partners at shebeens were independently associated with engaging in anal intercourse. Mathematical modeling showed that individual risks are significantly impacted by anal intercourse but probably not to the degree needed to drive a generalized HIV epidemic. Conclusions Anal intercourse likely plays a significant role in HIV infections among a small minority of South Africans who patronize alcohol serving establishments. Heterosexual anal intercourse, the most risky sexual behavior for HIV transmission, should not be ignored in HIV prevention for South African heterosexuals. However, this relatively infrequent behavior should not become the focus of prevention efforts.

  7. Heterosexual Rejection and Mate Choice: A Sociometer Perspective

    Full Text Available Previous studies about the effects of social rejection on individuals’ social behaviors have produced mixed results and tend to study mating behaviors from a static point of view. However, mate selection in essence is a dynamic process, and therefore sociometer theory opens up a new perspective for studying mating and its underlying practices. Based on this theory and using self-perceived mate value in the relationship between heterosexual rejection and mate choice as a mediating role, this current study examined the effects of heterosexual rejection on mate choice in two experiments. Results showed that heterosexual rejection significantly reduced self-perceived mate value, expectation, and behavioral tendencies, while heterosexual acceptance indistinctively increased these measures. Self-perceived mate value did not serve as a mediator in the relationship between heterosexual rejection and mate expectation, but it mediated the relationship between heterosexual rejection and mating behavior tendencies towards potential objects. Moreover, individuals evaded both rejection and irrelevant people when suffering from rejection.

    We examined sociodemographic, behavioral, and clinical characteristics associated with inconsistent condom use in a cross-sectional analysis of 145 sexually active HIV-serodiscordant heterosexual couples who participated in the California Partners Study II. All couples were aware of their HIV-serodiscordant status. Forty-five percent of couples reported having had unprotected vaginal or anal sex in the previous 6 months. In the multivariate couple-level analyses, factors independently associated with inconsistent (i.e., <100%) condom use in the previous 6 months included lower educational level, unemployment, African-American ethnicity, and practice of anal sex by the couple. Injection drug use was associated with inconsistent condom use among couples with younger HIV-infected partners. In addition, couples with HIV-infected partners who had higher CD4 cell counts and couples in which the HIV-infected male partner ever had sex with a man were more likely to use condoms inconsistently. Consistency of condom use did not depend on the gender of the HIV-infected partner or duration of sexual relationship. The findings suggest that many HIV-serodiscordant heterosexual couples remain at high risk of HIV transmission and may benefit not only from behavioral interventions but also from structural interventions aimed at improving their social and economic conditions.

    We set out to define the relative prevalence and common presentations of the various aetiologies of headache within an ambulant HIV-seropositive adult population in Kampala, Uganda. We conducted a prospective study of adult HIV-1-seropositive ambulatory patients consecutively presenting with new onset headaches. Patients were classified as focal-febrile, focal-afebrile, non-focal-febrile or non-focal-afebrile, depending on presence or absence of fever and localizing neurological signs. Further management followed along a pre-defined diagnostic algorithm to an endpoint of a diagnosis. We assessed outcomes during four months of follow up. One hundred and eighty patients were enrolled (72% women). Most subjects presented at WHO clinical stages III and IV of HIV disease, with a median Karnofsky performance rating of 70% (IQR 60-80).The most common diagnoses were cryptococcal meningitis (28%, n = 50) and bacterial sinusitis (31%, n = 56). Less frequent diagnoses included cerebral toxoplasmosis (4%, n = 7), and tuberculous meningitis (4%, n = 7). Thirty-two (18%) had other diagnoses (malaria, bacteraemia, etc.). No aetiology could be elucidated in 28 persons (15%). Overall mortality was 13.3% (24 of 180) after four months of follow up. Those without an established headache aetiology had good clinical outcomes, with only one death (4% mortality), and 86% were ambulatory at four months. In an African HIV-infected ambulatory population presenting with new onset headache, aetiology was found in at least 70%. Cryptococcal meningitis and sinusitis accounted for more than half of the cases.

    Measures of sexual interest tend to be more gender-specific in heterosexual men than in heterosexual women. Cognitive measures, such as viewing time to attractive stimuli, may also show similar patterns of gender-specificity or nonspecificity among men and women and thus serve as useful adjuncts to more direct measures of sexual interest. The objectives of the present research were to determine the extent of gender-specificity in women's viewing times for female pictures (varying in their perceived physical attractiveness) and explore the influence of social comparison of physical appearance on these patterns of responses. In Study 1, we recorded only women's viewing times for pictures of both genders, measured self-reported menstrual cycle phase, and manipulated the waist-to-hip ratio of the women in the female pictures. In Study 2, we recorded women's and men's viewing times, self-reported sexual attraction to pictures of males and females, and physical appearance social comparison. Study 1 found that heterosexual women's viewing time toward female pictures was not associated with manipulation of the perceived attractiveness of those pictures. Study 2 found that heterosexual men were more gender-specific than heterosexual women in their viewing time patterns. We also found that reported sexual attraction and physical appearance social comparison were associated with heterosexual women's viewing times for female pictures, while heterosexual men's viewing times were associated with sexual attraction only. Our results are discussed in relation to the utility of viewing time as an indicator of visual attention toward attractive or sexually appealing visual stimuli.

    INTRODUCTION: Little is known about the sexual and psychosocial health of non-heterosexual Danes. Based on a large population study, the aim of this article was to compare quality-of-life-related key variables of heterosexual and non-heterosexual men and women, aged 16-66. MATERIALS AND METHODS......: Cross-sectional data from the nationwide, representative Health and Morbidity Survey (n = 8496) were used to compare variables concerning both general and sexual well-being of self-identified heterosexual and non-heterosexual respondents. RESULTS: Nearly twice as many non-heterosexual than heterosexual...... men rated their sexual life as bad or very bad (22.5% versus 12.8%), while no statistical difference was seen among women (13.6% versus 10.6%). For both genders, significantly more non-heterosexuals than heterosexuals stated that their sexual needs were not met (17.9% versus 7.7% for men and 14...

    Full Text Available Objective: The aim of the study was to evaluate the correlation between CD4+ cell count and viral load with periodontal and dental status in HIV seropositive patient. Methods: Forty HIV seropositive patients were selected from the dental clinic of the Clementino Fraga Hospital in João Pessoa, Paraíba, Brazil. The Community Periodontal Index, Simplified Oral Hygiene Index and Decayed, Missing or Filled Teeth Index were determined. The values of CD4+ lymphocyte count and viral load were collected from the medical records. Descriptive analysis was made and Spearman’s correlation test was applied, with values of p<0.05 being significant. Results: HIV seropositive patients were aged 33 to 47 years (mean = 40 years, 26 were men and 14 women. The mean CD4+ lymphocyte count was 507.82±306.4 cells/mm3, with 41% being a high, 38.5% a medium and 20.5% a low level. Sixty-five percent of the patients had undetectable viral load, 12.5% had a high, 5% a low and 5% a medium viral load. Most patients (87.5% presented with periodontal disease, calculus was the most frequent condition (40%. The mean Decayed, Missing or Filled Tooth Index was 19.7±6.8, with prevalence of the missing component. There was significant statistical correlation between the CD4+ count and the periodontal condition, p=0.046. There was no significant correlation between the CD4+ count and the Decayed, Missing or Filled Teeth Index (p=0.469 and the Simplified Oral Hygiene Index (p=0.189 indexes, and between viral load and Decayed, Missing or Filled Teeth Index (p=0.452, the Simplified Oral Hygiene Index (p=0.158 and Community Periodontal Index (p=0.216. Conclusion: The periodontal condition was influenced to a greater by the CD4+ cell count than the viral load, while there was no correlation between the decayed condition and the CD4+ cell count or the viral load condition.

    Full Text Available Background. The CDC recommends persons at high-risk for HIV infection in the United States receive annual HIV testing to foster early HIV diagnosis and timely linkage to health care. Heterosexuals make up a significant proportion of incident HIV infections (>25%, but test for HIV less frequently than those in other risk categories. Yet factors that promote or impede annual HIV testing among heterosexuals are poorly understood. The present study examines individual/attitudinal-, social-, and structural-level factors associated with past-year HIV testing among heterosexuals at high-risk for HIV. Methods. Participants were African American/Black and Hispanic heterosexual adults (N=2307 residing in an urban area with both high poverty and HIV prevalence rates. Participants were recruited by respondent-driven sampling (RDS in 2012-2015 and completed a computerized structured assessment battery covering background factors, multi-level putative facilitators of HIV testing, and HIV testing history. Separate logistic regression analysis for males and females identified factors associated with past-year HIV testing.Results. Participants were mostly male (58%, African American/Black (75%, and 39 years old on average (SD = 12.06 years. Lifetime homelessness (54% and incarceration (62% were common. Half reported past-year HIV testing (50% and 37% engaged in regular, annual HIV testing. Facilitators of HIV testing common to both genders included sexually transmitted infection (STI testing or STI diagnosis, peer norms supporting HIV testing, and HIV testing access. Among women, access to general medical care and extreme poverty further predicted HIV testing, while recent drug use reduced the odds of past-year HIV testing. Among men, past-year HIV testing was also associated with lifetime incarceration and substance use treatment.Conclusions. The present study identified gaps in rates of HIV testing among heterosexuals at high-risk for HIV, and both common and

  15. Homicides between heterosexual intimates: Criminological and victimological characteristics

    Directory of Open Access Journals (Sweden)

    Simeunović-Patić Biljana J.

    2002-01-01

    Full Text Available In this paper the problem of homicidal violence between heterosexual intimates is analyzed, and the need for its treatment as a specific criminological issue denoted, having in mind many of its distinctive etiological and victimological dimensions. The presented findings of an empirical research on intimate homicides committed in Belgrade from 1985 to 1993 allowed for a testing of some hypotheses related to the factors of homicidal criminalization and victimization within the context of the intimate heterosexual relationships. The evidence on history and dynamics of deeply disturbed intimate relations, as well as some typical characteristics of male intimate partners in violent heterosexual relationships, are particularly considered. On the bases of research findings, it seems possible that the plausible preventive strategies can be developed.

    To compare self-identified lesbian, gay, and bisexual (LGB) college students to heterosexual peers and to each other on alcohol, tobacco and other drug (ATOD) measures and alcohol use consequences. Preexisting data (Falls 2009-2011) from the American College Health Association-National College Health Assessment (ACHA-NCHA-II) were analyzed. Bisexual college students had greater odds of ATOD use than heterosexual and gay/lesbian students. Bisexual women had the highest levels of use. LGB students had more serious consequences due to alcohol use. ATOD use among LGB students was more prevalent than heterosexuals during the past 30 days, year, and life-time. LGB students report more negative alcohol consequences.

  17. Comparing the Rates of Early Childhood Victimization across Sexual Orientations: Heterosexual, Lesbian, Gay, Bisexual, and Mostly Heterosexual.

    Directory of Open Access Journals (Sweden)

    Christopher Zou

    Full Text Available Few studies have examined the rates of childhood victimization among individuals who identify as "mostly heterosexual" (MH in comparison to other sexual orientation groups. For the present study, we utilized a more comprehensive assessment of adverse childhood experiences to extend prior literature by examining if MH individuals' experience of victimization more closely mirrors that of sexual minority individuals or heterosexuals. Heterosexual (n = 422 and LGB (n = 561 and MH (n = 120 participants were recruited online. Respondents completed surveys about their adverse childhood experiences, both maltreatment by adults (e.g., childhood physical, emotional, and sexual abuse and childhood household dysfunction and peer victimization (i.e., verbal and physical bullying. Specifically, MH individuals were 1.47 times more likely than heterosexuals to report childhood victimization experiences perpetrated by adults. These elevated rates were similar to LGB individuals. Results suggest that rates of victimization of MH groups are more similar to the rates found among LGBs, and are significantly higher than heterosexual groups. Our results support prior research that indicates that an MH identity falls within the umbrella of a sexual minority, yet little is known about unique challenges that this group may face in comparison to other sexual minority groups.

    In most experimental studies, emotional pictures are widely used as stimulus material. However, there is still a lack of standardization of picture stimuli displaying erotic relationships, despite the association between a number of psychological problems and severe impairments and problems in intimate relationships. The aim of the study was to test a set of erotic stimuli, with the potential to be used in experimental studies, with heterosexual female subjects. Twenty International Affective Picture System (IAPS) pictures and an additional 100 pictures showing romantic but not explicitly sexual scenes and/or attractive single males were selected. All pictures were rated with respect to valence, arousal, and dominance by 41 heterosexual women and compared to pictures with negative, positive, and neutral emotional valence. Erotic IAPS pictures and our additional erotic pictures did not differ in any of the evaluation dimensions. Analyses of variance (ANOVAs) for valence, arousal, and dominance comparing different picture valence categories showed strong effects for category. However, valence was not significantly different between erotic and positive pictures, while arousal and control were not significantly different between positive and neutral pictures. The pictures of our new set are as positive for heterosexual women as highly positive IAPS pictures, but higher in arousal and dominance. The picture set can be used in experimental psychiatric studies requiring high numbers of stimuli per category. Limitations are the restriction of stimuli application to heterosexual females only and to self-report data. Copyright © 2011 Elsevier Ltd. All rights reserved.

  7. The heterosexual singles scene: putting danger into pleasure.

    1996-06-01

    The juxtaposition of pleasure and danger has engaged many feminist theorists and researchers in the field of sexuality. This article presents a theoretical analysis of the ambiguous and complex relationship between 'pleasure', 'danger' and contemporary feminist theory. In doing so, it offers an understanding of the ways in which the categories of pleasure and danger operate within the discourses of heterosexuality to construct perceptions of risk in the context of HIV/AIDS. Data were collected from a study of the sexual attitudes and practices of 112 sexually-active, single, heterosexual adults (58 men and 54 women), aged 20 to 40 years (mean = 27 years) who agreed to be interviewed when approached at night-clubs and public "singles' bars around Melbourne, Australia. The qualitative analysis presented here is consistent with a poststructuralist feminism. First, we discuss how sexuality cannot be cast solely as pleasurable or dangerous. Second, we demonstrate how heterosexualized notions of pleasure and danger operate to provide misperceptions of risk from HIV/AIDS transmission. Third, we identify the ways in which the logic of identity functions to obscure risk within the discourse of heterosexuality, and finally we attempt to forge new ways of practising pleasure which disrupt heterosexist discourses and allow for pleasures which incorporate danger.

    The aim of this study was to describe the epidemiology and utilization of anti-hepatitis B core protein(+) and anti-hepatitis C virus(+) organ donor referrals in a large organ procurement organization. Between 1995 and 2006, 3,134 deceased organ donor referrals were tested for anti-HBc and anti-HCV using commercial assays. The prevalence of anti-HCV(+) organ donor referrals significantly increased from 3.4% in 1994-1996 to 8.1% in 2003-2005 (P organ donor referrals remained unchanged at 3%-4% (P = .20). The 112 anti-HBc(+) (3.5%) and 173 anti-HCV(+) (5.5%) organ donor referrals were significantly older and more likely to be noncaucasian than seronegative organ donor referrals (P donor organs were significantly lower compared with seronegative organ donors (P donors over time (21% vs 46%; P = .026), whereas utilization of anti-HCV(+) liver donors remained unchanged over time (5% vs 18%; P = .303). In summary, the proportion of anti-HCV(+) organ donor referrals has significantly increased and the proportion of anti-HBc(+) organ donor referrals has remained stable. Both thoracic and abdominal organs from seropositive donors are largely underutilized. Copyright © 2010 Elsevier Inc. All rights reserved.

    2018-06-01

    This study examined the relationship between ambient workplace heterosexism, emotional reactions (i.e., fear and anger), and outcomes for sexual minority and heterosexual employees. Five hundred thirty-six restaurant employees (68% female, 77% White) completed an online survey assessing the variables of interest. Results showed that greater experiences of ambient workplace heterosexism were associated with heightened fear and anger and, in turn, with heightened psychological distress (for fear) and greater physical health complaints, turnover intentions, and lowered job satisfaction (for anger). Fear also mediated the relationship between ambient workplace heterosexism and psychological distress. In addition, sexual orientation moderated the relationship between ambient workplace heterosexism and fear such that sexual minority employees reported more fear than heterosexuals with greater ambient heterosexism. These effects occurred after controlling for personal experiences of interpersonal discrimination. Our findings suggest that ambient workplace heterosexism can be harmful to all employees, not only sexual minorities or targeted individuals. Copyright © 2018 John Wiley & Sons, Ltd.

  14. Sexual and romantic jealousy in heterosexual and homosexual adults.

    Science.gov (United States)

    Harris, Christine R

    2002-01-01

    Several theorists have claimed that men are innately more upset by a mate's sexual infidelity and women are more upset by a mate's emotional infidelity because the sexes faced different adaptive problems (for men, cuckoldry; for women, losing a mate's resources). The present work examined this theory of jealousy as a specific innate module in 196 adult men and women of homosexual and heterosexual orientations. As in previous work, heterosexuals' responses to a forced-choice question about hypothetical infidelity yielded a gender difference. However no gender differences were found when participants recalled personal experiences with a mate's actual infidelity. Men and women, regardless of sexual orientation, on average focused more on a mate's emotional infidelity than on a mate's sexual infidelity. Responses to hypothetical infidelity were uncorrelated with reactions to actual infidelity. This finding casts doubt on the validity of the hypothetical measures used in previous research.

    Full Text Available Background: there are few studies at the population level on the prevalence of violence in heterosexual relationships. This study demonstrated the reality of this phenomenon in our context. Objective: to determine the prevalence of psychological and physical violence among heterosexual couples in the city of Cienfuegos in 2010. Methods: a cross-sectional study of adults aged 15 to 74 years was conducted in six health areas. An equal probability sample of 1873 subjects was selected. The variables included psychological and physical violence, sex, age, skin color, marital status, educational level and history of living in troubled homes. The results were processed using SPSS 15.0. Results: prevalence of psychological and physical violence among couples was approximately six out of ten with different frequency levels. Psychological violence rose to 82.3 % and physical violence to 96.3 % when the couple lived together. Women reported being victims of violence from age 35 to 44 and men from age 25 to 34. Seventy point eight percent of couples who had middle school education reported suffering physical violence while 63 % of those with university education reported psychological violence. Fifty-one point eight percent of the study population was victim of physical violence during childhood. Conclusions: prevalence of psychological and physical violence among heterosexual couples in the sample studied in Cienfuegos is higher than the mean in the general population.

  17. Practicing vaginistic femininity: Doing bodies, enacting normative heterosexuality

    2015-12-01

    Full Text Available Vaginismus is a female sexual pain disorder, characterized by contractions of the pubococcygeus (PC muscle that surrounds the outer third of the vagina, which makes penetrative penile-vaginal intercourse (coitus, insertion of a finger or tampon and gynecological examinations hard or impossible, and painful for the woman. The condition is believed to be associated with negative beliefs, attitudes or experiences related to sex. Vaginismus has important social repercussions in everyday life, which acquire meaning in the context of hegemonic heterosexuality. In line with theories of performativity, heterosexuality and gender are normatively and performatively linked sets of practices, with coitus being the central practice of heterosexuality and thus defining for one’s gender. Thus, the inability of vaginistic women to perform coitus impairs their performance of normative heterogender. In this article I address gender experiences of women with primary vaginismus, by looking at social and bodily practices they engage in. In the first part of the article, I explore how women with primary vaginismus do (vaginistic heterogender. In the second part I address the practices they do in order to ‘overcome’ vaginismus, thus improving their performance of normative heterogender, and argue that these practices are gendering themselves.

    Assessing couple relationships across diverse languages and cultures has important implications for both clinical intervention and prevention. This is especially true for nontraditional relationships potentially subject to various expressions of negative societal evaluation or bias. Few empirically validated measures of relationship functioning have been developed for cross-cultural applications, and none have been examined for their psychometric sufficiency for evaluating same-sex couples across different languages and cultures. The current study examined the psychometric properties of an Italian translation of the Marital Satisfaction Inventory - Revised (MSI-R), a 150-item 13-scale measure of couple relationship functioning, for its use in assessing the intimate relationships of gay and lesbian couples in Italy. Results for these couples were compared to data from heterosexual married and unmarried cohabiting couples from the same geographical region, as well as to previously published data for gay, lesbian, and unmarried heterosexual couples from the United States. Findings suggest that, despite unique societal pressures confronting Italian same-sex couples, these relationships appear resilient and fare well both overall and in specific domains of functioning compared to heterosexual couples both in Italy and the United States. © 2014 Family Process Institute.

    2017-06-01

    Full Text Available Cytomegalovirus (CMV is the most frequent congenital virus infection worldwide. The risk of congenital CMV (cCMV transmission is highest in seronegative women who acquire primary CMV infection during pregnancy. A growing body of evidence indicates that secondary CMV infections in pregnant women with preconceptual immunity (either through reactivation of latent virus or re-infection with a new strain of CMV contribute to a much greater proportion of symptomatic cCMV than was previously thought. Here, we describe a case of symptomatic cCMV infection in the newborn of a woman with proven immunity prior to pregnancy. Diagnosis was confirmed by CMV PCR from amniotic fluid and fetal MR imaging. The newborn presented with typical cCMV symptoms including jaundice, hepatosplenomegaly, cholestasis, petechiae, small head circumference, and sensorineural hearing loss, the most common neurologic sequela. CMV was detected in infant blood and urine by PCR, and intravenous ganciclovir was initiated and continued orally for 6 weeks totally. Apart from persisting right-sided deafness, the child exhibited normal neurological development up through the last follow-up at 4.5 years. To date, the most effective strategy to prevent vertical CMV transmission is hygiene counseling for women of childbearing age, which, in our case, and in concordance with recent literature, applies to seronegative, as well as seropositive, women. Once an expecting mother shows seroconversion or signs of an active CMV infection, there are no established procedures to reduce the risk of transmission, or therapeutic options for the fetus with signs of infection. After birth, symptomatic infants can be treated with ganciclovir to inhibit viral replication and improve hearing ability and neurodevelopmental outcome. A comprehensive review of the literature, including our case study, reveals the most current and significant diagnostic and treatment options available. In conclusion, the triad

    2014-01-01

    Full Text Available Background & objectives: Lymphadenopathy and haematological alterations are the earliest manifestations with other associated opportunistic infections and malignancies. Hence, there is a need for simple investigations like fine needle aspiration cytology (FNAC for evaluation of HIV lymphadenopathy and a haemogram to interpret the haematological alterations. This study was undertaken to analyze the cytological patterns of lymph node lesions in HIV/AIDS patients, to compare with available clinico-pathological and haematological parameters to segregate lymphadenopathy cases for further evaluation. Methods: In the present study, 129 HIV seropositive patients were included. Lymph node aspirates were stained routinely with hematoxylin and eosin and Ziehl-Neelsen (Z-N stains. Special stains and cultures were done in selected patients. Peripheral smears were taken from all the patients and CD4 counts were recorded. Tuberculous lymphadenitis was further categorized. Acid fast bacilli (AFB grading was done on Z-N positive smears. Each lesion was compared with CD4 counts, WHO clinical staging and haematological picture. Results: Cytological diagnosis in 129 patients included tuberculous (n=54, 41.9%, reactive lymphadenopathy (n=46, 35.6%, suppurative (n=16, 12.4% lymphadenitis, non-Hodgkin′s lymphoma (n=4, 3.1%, and Hodgkin′s lymphoma, secondary deposits, other granulomatous lesions, and cryptoccocal lymphadenitis in one patient each. The predominant cytomorphological pattern in tuberculous lymphadenitis was caseous necrosis + epithelioid granuloma formation (51.85%. Grade 2+ Z-N grading was noted in 62.96 per cent of AFB positive smears. CD4 counts showed a descending pattern with progression of WHO clinical staging. Cytopenia was more common in WHO clinical stage IV disease. Interpretation & conclusions: Lymph node cytology was found to be a useful tool for segregating lymphadenopathy cases for further evaluation and for identification of

    In 2012, the U.S. Food and Drug Administration proposed nine graphic health warnings (GHWs) on cigarette packaging that were rated equally effective across racial/ethnic, education, or income groups of adult smokers. However, data on GHW effectiveness among sexual and gender minority (SGM) adults, who have higher smoking prevalence, are currently lacking. This study analyzed whether perceived effectiveness of GHWs differed by gender and sexual orientation. Data came from a randomized experiment among 1,200 adults with an oversample from low socioeconomic status groups, conducted between 2013 and 2014 in three Massachusetts communities. Participants viewed and rated the effectiveness of nine GHWs. Mixed effects regression models predicted perceived effectiveness with gender and sexual orientation, adjusting for repeated measurements, GHWs viewed, age, race, ethnicity, smoking status, and health status. Female heterosexuals rated GHWs as more effective than male heterosexual, lesbian, and transgender and other gender respondents. There was no significant difference between female and male heterosexuals versus gay, male bisexual, or female bisexual respondents. Differences by gender and sexual orientation were consistent across all nine GHWs. Significant correlates of higher perceived effectiveness included certain GHWs, older age, being African-American (vs white), being Hispanic (vs non-Hispanic), having less than high school education (vs associate degree or higher), and being current smokers (vs non-smokers). Perceived effectiveness of GHWs was lower in certain SGM groups. We recommend further studies to understand the underlying mechanisms for these findings and investments in research and policy to communicate anti-smoking messages more effectively to SGM populations.

    The aims of the study were to estimate Toxoplasma gondii seroprevalence in pet cats in Norway and to evaluate risk factors for seropositivity. Additionally, serum biochemistry and haematological variables for T gondii seropositive and seronegative cats were compared. A convenience sample of surplus sera submitted to the Central Laboratory, Norwegian University of Life Sciences, was collected. The samples were from healthy cats and cats with a variety of diseases. Analyses for IgG antibodies to T gondii were performed with a commercial direct agglutination test, with 1:40 as the threshold value. For risk factor analysis a logistic regression model of the relationship between predictors and the outcome was applied. One hundred and ninety-six of 478 cats were seropositive for T gondii, and the estimated seroprevalence in the study sample was 41.0% (95% confidence interval 36.6-45.4). Compared with domestic cats, pedigree cats had reduced risk for Toxoplasma seropositivity (odds ratio [OR] 0.42). Males had increased risk (OR 1.63) compared with females. The effect of age was highly significant, and an increase in the cats' age across the interquartile range (IQR; 52-160 months/4-13 years of age) doubled the risk of Toxoplasma seropositivity (OR 2.11). The risk for Toxoplasma seropositivity among cats living in Oslo was significantly reduced (OR 0.51) when compared with the rest of Norway. Pet cats in Norway appear to be commonly exposed to T gondii. Signalment and geographical region influenced the odds of Toxoplasma seropositivity, whereas health status did not. © ISFM and AAFP 2015.

  3. Enhancing masculinity by slandering homosexuals: the role of homophobic epithets in heterosexual gender identity.

    Carnaghi, Andrea; Maass, Anne; Fasoli, Fabio

    2011-12-01

    The current studies investigate the effects of homophobic labels on the self-perception of heterosexual males, hypothesizing that when exposed to homophobic epithets, they are motivated to underline their masculinity and claim a distinctly heterosexual identity by taking distance from homosexuals and, to a lesser degree, from women. Heterosexual male participants were subliminally (Study 1) and supraliminally (Study 2) primed either by a homophobic epithet or by a category label, and completed the Traditional Beliefs About Gender and Gender Identity scale. Participants stressed their heterosexual identity, but not their gender distinctiveness, when exposed to homophobic epithets, compared to category labels. Study 2 demonstrated that the relation between the homophobic label and the participants' heterosexual identity was mediated by how negatively they reacted to the antigay label. Heterosexual identity was enhanced in reaction to homophobic labels but not to an equally derogatory label referring to regional identity. Results are discussed within an intergroup framework.

    Enterovirus A71 (EV-A71), which is transmitted by the fecal-oral route, causes hand, foot and mouth disease and, rarely, severe neurological complications. In Malaysia, the indigenous rural community (Orang Asli) has a high prevalence of parasitic diseases due to poor sanitation, water supply and hygiene practices. This cross-sectional study compared the seroepidemiology of EV-A71 among rural Orang Asli and urban Kuala Lumpur populations in West Malaysia, and determined the risk factors associated with EV-A71 seropositivity in rural Orang Asli. Seropositive rates were determined by neutralization assay. EV-A71 seropositivity was strongly associated with increasing age in both populations. Rural Orang Asli children ≤12 years had significantly higher EV-A71 seropositivity rates than urban Kuala Lumpur children (95.5% vs 57.6%, P water (adjusted OR 6.2, 95% CI 2.3-16.6, P water may reduce the risk of EV-A71 infection. With significantly higher EV-A71 seropositive rates, younger rural children should be a priority target for future vaccination programs in Malaysia.

    Full Text Available The human adenovirus 36 (Ad-36 is causally and correlatively associated in animals and humans, respectively, with increased adiposity and altered metabolic profile. In previous studies, the relationship between Ad-36 seropositivity with obesity was established in adults and children. We evaluated the association of positive antibodies to Ad-36 with obesity and metabolic profile in Mexican children. Seventy-five children with normal-weight and 82 with obesity were studied in this research. All children had a clinic assessment which included weight, height, body circumferences, and skinfold thickness. Laboratory analyzes included triglycerides, total cholesterol, high-density lipoprotein, low-density lipoprotein, and glucose and insulin levels. An enzyme-linked immunosorbent assay (ELISA was used to determine the antibodies to Ad-36 in the serum samples. The overall Ad-36 seroprevalence was 73.9%. Ad-36 seropositivity had a higher prevalence in obese children than in normal weight group (58.6 versus 41.4%, P=0.007. Ad-36 seropositivity was associated with obesity (OR=2.66, P=0.01 and high-density lipoprotein <40 mg/dL (OR=2.85, P=0.03. The Ad-36 seropositive group had greater risk of 4 metabolic abnormalities compared with those children without none alteration. In summary, Ad-36 seropositivity was associated with obesity and low HDL-c levels in the sample of children studied.

    Full Text Available Foot and mouth disease (FMD and infectious bovine rhinotracheitis (IBR are two important infectious diseases of cattle. Inactivated FMD vaccines are the most powerful tools to protect animals against FMD. Previous studies showed that recombinant IBR-FMD viruses protected cattle from virulent BHV-1 challenge and induced protective levels of anti-FMDV antibodies. FMD is considered to be endemic in Turkey and inactivated oil adjuvanted vaccines are used for the immunization of cattle. Previous studies showed that seroprevalence of IBR in the Turkey’s dairy herd more than 50%. In this study, antibody response in IBR seropositive cattle following vaccination against FMD was investigated. IBR seropositive (n=208 and IBR seronegative (n=212 cattle were vaccinated with oil-adjuvanted bivalent vaccine (containing O1 Manisa, A22 Iraq FMDV strains. Solid-phase competitive ELISA (SPCE was used to measure antibodies produced in cattle. Protective level of antibody against serotype O was detected in 77.4% and serotypes A in 83.6% of IBR seropositive cattle. Protective level of antibody against serotype O antibody was detected in 49% and serotypes A in 66.9% of IBR seronegative cattle. The differences between the protection rates against both serotype O (P=0.0001 and serotype A (P=0.0001 in IBR seropositive and seronegative animals were statistically important (Fisher’s exact test, P<0.01. Results showed that after FMD vaccination, IBR seropositive animals produced high titres of antibodies than seronegative animals.

    Bovine brucellosis is an important zoonotic disease caused by the bacterium Brucella abortus that leads to economic losses due to animal discard and commercial restrictions. Since positive animals for brucellosis are culled, little is known about the pathogenesis of this disease. Therefore, the aims of this study were to evaluate possible changes in the activity of deaminase adenosine (ADA) and the oxidative stress in cows seropositives for brucellosis (Experiment I), and to evaluate the seroprevalence of B. abortus in dairy cows from the Western state of Santa Catarina, Southern Brazil (Experiment II). The Experiment I evaluated 20 pregnant cows: ten seropositives for B. abortus and ten seronegatives that were used as controls. The ADA activity and markers of oxidative stress (TBARS, catalase (CAT) and superoxide dismutase (SOD)) were evaluated in these animals. A reduction in the activity of ADA and catalase enzymes in seropositive animals was observed (p cows infected by B. abortus (p cows of 69 herds. The serodiagnosis was performed using two tests: buffered acidified antigen and 2-mercaptoethanol. However, none of the serum samples were positive for B. abortus. Although we did not find seropositive animals for brucellosis in our study, the disease still requires continued surveillance, due to its economic impact, and to the oxidative stress caused by it, which may have contributed to cases of abortion in three seropositive cows (Experiment I) in the final third of the gestation.

    We sought to examine sexual violence victimization in childhood and sexual risk indicators in young adulthood in a primarily Latina and Black cohort of "mostly heterosexual" and heterosexual women in the Project on Human Development in Chicago Neighborhoods (PHDCN). In 2000, a comprehensive survey that assessed sexual orientation, sexual risk indicators, and sexual abuse victimization was completed by 391 young women (aged 18 to 24 years) who had participated in PHDCN. We used multivariable regression methods to examine sexual orientation group differences in sexual risk indicators and to assess whether childhood sexual abuse may mediate relationships. Compared with self-reported heterosexual women, self-reported "mostly heterosexual" women were more likely to report having been the victim of childhood sexual abuse, to have had a sexually transmitted infection, to report an earlier age of first sexual intercourse, and to have had more sexual partners. Childhood sexual abuse did not mediate relationships between sexual orientation and sexual risk indicators. Our findings add to the evidence that "mostly heterosexual" women experience greater health risk than do heterosexual women. In addition, "mostly heterosexual" women are at high risk for having experienced childhood sexual abuse.

    Studies investigating sexual arousal exist, yet there are diverging findings on the underlying neural mechanisms with regard to sexual orientation. Moreover, sexual arousal effects have often been confounded with general arousal effects. Hence, it is still unclear which structures underlie the sexual arousal response in homosexual and heterosexual men. Neural activity and subjective responses were investigated in order to disentangle sexual from general arousal. Considering sexual orientation, differential and conjoint neural activations were of interest. The functional magnetic resonance imaging (fMRI) study focused on the neural networks involved in the processing of sexual stimuli in 21 male participants (11 homosexual, 10 heterosexual). Both groups viewed pictures with erotic content as well as aversive and neutral stimuli. The erotic pictures were subdivided into three categories (most sexually arousing, least sexually arousing, and rest) based on the individual subjective ratings of each participant. Blood oxygen level-dependent responses measured by fMRI and subjective ratings. A conjunction analysis revealed conjoint neural activation related to sexual arousal in thalamus, hypothalamus, occipital cortex, and nucleus accumbens. Increased insula, amygdala, and anterior cingulate gyrus activation could be linked to general arousal. Group differences emerged neither when viewing the most sexually arousing pictures compared with highly arousing aversive pictures nor compared with neutral pictures. Results suggest that a widespread neural network is activated by highly sexually arousing visual stimuli. A partly distinct network of structures underlies sexual and general arousal effects. The processing of preferred, highly sexually arousing stimuli recruited similar structures in homosexual and heterosexual males. © 2011 International Society for Sexual Medicine.

    Toxoplasma gondii is a cosmopolitan protozoan that causes disease in several species, including humans. In cats, these infections are usually asymptomatic, but in other species they can lead to high levels of inflammatory and cell damage markers, causing cellular damage. Therefore, the aim of this study was to measure levels of tumor necrosis factor (TNF-α), reactive oxygen species (ROS), and nitric oxide (nitrite/nitrate-NO x ) in the serum of cats seropositive for T. gondii. Initially, we investigated the presence of antibodies against T. gondii in cats in the city of Concordia, Santa Catarina, Brazil, with the use of indirect immunofluorescence (IFA), and found 30 cats seropositive for T. gondii and 30 seronegative cats. In this study, seropositive cats showed higher levels of TNF-α, ROS, and NO x compared to seronegative cats. Although cats do not show clinical signs of disease, constant inflammatory response can cause cell damage, which over time may adversely affect the animal.

    We performed a cross-sectional study of Trypanosoma cruzi seroprevalence in 14 communities in three provinces of Ecuador and estimated the magnitude of the association of seropositive individuals within households. A total of 3,286 subjects from 997 households were included. Seroprevalence was 5.7%, 1.0%, and 3.6% in subjects in the Manabí, Guayas, and Loja provinces, respectively. Seroprevalence increased with increasing age in Manabí and Guayas, whereas in Loja, the highest prevalence occurred in children Loja, the odds of seropositivity were more than two times greater for an individual living in a household with another seropositive person. Our results indicate that transmission of T. cruzi is ongoing in Ecuador, although intensity of transmission and mechanisms of interaction between humans and the insect vectors of disease vary between geographic regions.

  12. Bacterial vaginosis associated with increased risk of female-to-male HIV-1 transmission: a prospective cohort analysis among African couples.

    Full Text Available Bacterial vaginosis (BV, a disruption of the normal vaginal flora, has been associated with a 60% increased risk of HIV-1 acquisition in women and higher concentration of HIV-1 RNA in the genital tract of HIV-1-infected women. However, whether BV, which is present in up to half of African HIV-1-infected women, is associated with an increase in HIV-1 transmission to male partners has not been assessed in previous studies.We assessed the association between BV on female-to-male HIV-1 transmission risk in a prospective study of 2,236 HIV-1-seropositive women and their HIV-1 uninfected male partners from seven African countries from a randomized placebo-controlled trial that enrolled heterosexual African adults who were seropositive for both HIV-1 and herpes simplex virus (HSV-2, and their HIV-1-seronegative partners. Participants were followed for up to 24 months; every three months, vaginal swabs were obtained from female partners for Gram stain and male partners were tested for HIV-1. BV and normal vaginal flora were defined as a Nugent score of 7-10 and 0-3, respectively. To reduce misclassification, HIV-1 sequence analysis of viruses from seroconverters and their partners was performed to determine linkage of HIV-1 transmissions. Overall, 50 incident HIV-1 infections occurred in men in which the HIV-1-infected female partner had an evaluable vaginal Gram stain. HIV-1 incidence in men whose HIV-1-infected female partners had BV was 2.91 versus 0.76 per 100 person-years in men whose female partners had normal vaginal flora (hazard ratio 3.62, 95% CI 1.74-7.52. After controlling for sociodemographic factors, sexual behavior, male circumcision, sexually transmitted infections, pregnancy, and plasma HIV-1 RNA levels in female partners, BV was associated with a greater than 3-fold increased risk of female-to-male HIV-1 transmission (adjusted hazard ratio 3.17, 95% CI 1.37-7.33.This study identified an association between BV and increased risk of HIV

    Over 85% of cervical cancer cases and deaths occur in developing countries. HIV-seropositive women are more likely to develop precancerous lesions that lead to cervical cancer than HIV-negative women. However, the literature on cervical cancer prevention in seropositive women in developing countries has not been reviewed. The aim of this study is to systematically review cervical cancer prevention modalities available for HIV-seropositive women in developing countries. This protocol was developed by following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) statement, and the systematic review will be reported in accordance with the PRISMA guidelines. Embase, MEDLINE, PubMed, CINAHL and Cochrane Library will be searched from inception up to date of final search, and additional studies will be located through citation and reference list tracking. Eligible studies will be randomised controlled trials, prospective and retrospective cohort studies, case-control and cross-sectional studies carried out in developing countries. Studies will be included if they are published in English and examine cervical cancer prevention modalities in HIV-seropositive women. Results will be summarised in tables and, where appropriate, combined using meta-analysis. This review will address the gap in evidence by systematically reviewing the published literature on the different prevention modalities being used to prevent cervical cancer in HIV-seropositive women in developing countries. The findings may be used to inform evidence-based guidelines for prevention of cervical cancer in seropositive women as well as future research. PROSPERO CRD42017054678 .

    Rheumatoid arthritis (RA) is a chronic, inflammatory disease associated with increased risk of cardiovascular (CV) disease. Arterial stiffness (AS) is an independent predictor of CV events. This study aimed to analyse local carotid AS parameters in seronegative and seropositive RA patients. Of 347 consecutive RA patients, we selected specifically those who were free of established CV diseases and risk factors. As a result, 140 patients (126 women, 52.2 ± 10 years) and 140 healthy controls (122 women, 52.7 ± 8.0 years) were enrolled into this study. The common carotid AS was evaluated using radio frequency echo-tracking system to determine the local carotid pulse wave velocity (cPWV) and carotid intima-media thickness (cIMT). Based on rheumatoid factor (RF) and/or anti-citrullinated protein antibody (ACPA) positivity, RA patients were categorized into seronegative and seropositive subgroups. Carotid PWV was determined to be significantly higher in all patients and subgroups than controls (p < .001 for all). Although cIMT was similar between the patients, controls and seropositive subgroup, seronegative patients had significantly higher cIMT compared to controls (p = .035) and seropositive group (p = .010). Moreover, a significant positive correlation was found between cPWV and age (r: 0.603, p < .001), ESR (r: 0.297, p = .004), ACPA (r: 0.346, p = .001) and cIMT (r: 0.290, p = .005) in seropositive patients. RA per se is sufficient to cause arteriosclerosis in the absence of classical CV risk factors. However, arterial hypertrophy is only increased in seronegative patients but not in seropositive group.

    Coxiella burnetii is a zoonotic bacterium, and infection in goats with this bacterium can result in abortion, stillbirth or birth of non-viable kids. A cross-sectional study was conducted to identify the seroprevalence and risk factors for C. burnetii exposure in Ontario goats. Sera were collected between August 2010 and February 2012, and tested for C. burnetii specific antibodies using an enzyme-linked immunosorbent assay (IDEXX). Overall, 63.2% (48/76, 95% CI=51.9-73.4) of farms had one or more seropositive goats. A higher farm-level seroprevalence of 78.6% (33/42) was found on dairy goat farms, compared to 44.1% (15/34) on meat goat farms (pgoats were seropositive. Similarly, a higher individual-level seroprevalence was identified for dairy goats (43.7%, 633/1447) compared to meat goats (10.8%, 81/748) (pfarm-level clustering identified risk factors associated with seropositivity (pgoat farms were located in a 5-km radius, goats had 5.6 times (95% CI=1.01-30.8) times the odds of seropositivity compared to those that were not. Relative to goats from farms where all kidding pen hygiene was practiced (adding bedding, removing birth materials and disinfection after kidding), goats from farms which only added bedding and removed birth materials had a higher odds of seropositivity (OR=19.3, 95% CI=1.1-330.4), as did goats from farms which practiced none of these measures (OR=161.0, 95% CI=2.4-10822.2). An interaction term revealed kidding outdoors when there were no swine on farm had a protective effect on seropositivity compared to kidding indoors, or kidding outdoors with swine on the farm. These results can inform strategies to mitigate exposure to C. burnetii in Ontario. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available Sera from 432 small ruminants (335 sheep and 97 goats from 72 farms in Duhok Province, northern Iraq, were collected to investigate risk factors associated with brucellosis seropositivity. Serum samples were tested using the Rose Bengal test (RBT and an indirect enzyme-linked immunosorbent assay (iELISA. Using parallel interpretation, RBT and iELISA results showed that 31.7% (95% confidence interval (CI: 26.1, 36.3 of sheep and 34.0% (95% CI: 24.7, 44.3 of goats had antibodies against Brucella in the study area. A random-effects multivariable logistic regression model indicated that a higher chance of being seropositive (odds ratio (OR = 1.7; 95% 1.4; 2.2 was associated with an increase in the age of animals. The odds of Brucella seropositivity in flocks where sheep and goats grazed together was 2.0 times higher (95% CI: 1.08; 3.9 compared to flocks where sheep and goats grazed separately. The odds of Brucella seropositivity in small ruminants was 2.2 higher (95% CI: 1.2; 4.3 for animals originating from farms with a history of goat abortion in the preceding 12 months. In contrast, for every 1000 Iraqi Dinars (~0.85 US Dollar spent by the farmers on control of Brucella in their flocks, the odds of Brucella seropositivity decreased significantly (OR = 0.9, p-value = 0.021. The final model also indicated significant differences in Brucella seropositivity between the different districts of Duhok Province. This study provides a contribution to the epidemiology of brucellosis in small ruminants in northern Iraq.

    Full Text Available After HIV diagnosis, heterosexuals in high-poverty urban areas evidence delays in linkage to care and antiretroviral therapy initiation compared to other groups. Yet barriers to/facilitators of HIV care among these high-risk heterosexuals are understudied. Under the theory of triadic influence, putative barriers to HIV care engagement include individual/attitudinal-level (e.g., fear, medical distrust, social-level (e.g., stigma, and structural-level influences (e.g., poor access. Participants were African-American/Black and Hispanic adults found newly diagnosed with HIV (N = 25 as part of a community-based HIV testing study with heterosexuals in a high-poverty, high-HIV-incidence urban area. A sequential explanatory mixed-methods design was used. We described linkage to HIV care and clinical outcomes [CD4 counts, viral load (VL levels] over 1 year, and then addressed qualitative research questions about the experience of receiving a new HIV diagnosis, its effects on timely engagement in HIV care, and other barriers and facilitators. Participants were assessed five times, receiving a structured interview battery, laboratory tests, data extraction from the medical record, a post-test counseling session, and in-person/phone contacts to foster linkage to care. Participants were randomly selected for qualitative interviews (N = 15/25 that were recorded and transcribed, then analyzed using systematic content analysis. Participants were 50 years old, on average (SD = 7.2 years, mostly male (80%, primarily African-American/Black (88%, and low socioeconomic status. At the first follow-up, rates of engagement in care were high (78%, but viral suppression was modest (39%. Rates improved by the final follow-up (96% engaged, 62% virally suppressed. Two-thirds (69% were adequately retained in care over 1 year. Qualitative results revealed multi-faceted responses to receiving an HIV diagnosis. Problems accepting and internalizing one

    Few investigations of sexual attitudes have restricted their focus to individuals' preferences for specific behaviors within a heterosexual relationship. None have examined gender differences in a broad and multidimensional array of such behavioral particulars. As part of an effort to develop a measure of preferred scripts in heterosexual couples, 258 men and women reported how much they agreed or disagreed with 74 statements of preference. A reduced and factor analyzed questionnaire included 38 items and was administered to a second sample (N = 228). Results offer qualified support that, compared to women, men are more erotophilic and show a stronger preference for incorporating erotic materials as well as drugs and alcohol into sexual relations with their partner. These results were more robust in the second sample, in which almost half of the subjects were tested in same-sex groups. Across both samples, women showed stronger preferences for activities reflecting romanticism. No gender differences were evident in sexual conventionality or in preference regarding the general use of contraceptives. However, results suggest that both sexes respond more favorably to a partner-focused or unspecified contraceptive method than to a self-focused method.

    1996-04-01

    This article describes the development and evaluation of an instrument that measures preferences for specific sexual behaviors of heterosexual men and women in a dyadic context. In Study 1, 74 statements of preference were reduced to 46 on the basis of reliability and range of responses. Factor analysis revealed that 27 of the 46 items loaded on 6 factors: Erotophilia, Use of Contraception, Conventionality, Use of Erotica, Use of Drugs/Alcohol, and Romanticism. In Study 2, factor analysis of fresh data from a second sample cross-validated these results. To establish construct validity of the revised 27-item Inventory of Dyadic Heterosexual Preferences (IDHP), relationships between each of its 6 scales and 6 criterion measures were examined. These analyses suggested that the last scale is more accurately characterized by the term Romantic Foreplay. We conclude that the IDHP measures 6 distinct domains of sexual preference with a brief, psychometrically sound instrument. Potential applications of the IDHP, suggestions for future research, and strengths and limitations of the current investigation are discussed.

    A number of reports from Australia and abroad, detailing the results of surveys of heterosexuals' sexual practice, have indicated that most heterosexuals are not changing their sexual behavior despite the present context of a global HIV/AIDS pandemic, and despite there being a reasonably accurate knowledge of HIV transmission among survey respondents. However, it does appear that safe sex messages are getting through to and bringing about the gradual adoption of risk reduction behavior among young university students. Findings are reported from surveys of 18-19-year-old male and female students at Macquarie and Sydney Universities during 1987-90. 55 and 66 students were surveyed in 1987 and 1989, respectively, at the University of Sydney, while 700, 564, and 709 students were surveyed in 1988, 1989, and 1990, respectively, at Macquarie University. 45-55% of students had experienced oral/genital sex, 45-60% vaginal intercourse, and 4-7% anal sex. The students generally know that kissing and masturbation are safe sex practices, and they also appear to accept that condom use decreases the risk of exposure to HIV. The most dangerous sex practices were judged to be unprotected intercourse with regular and casual partners, but especially with casual partners, and withdrawal and oral/genital sex with casual partners. When compared with older students, these 18-19 year old students were significantly more likely to use condoms in vaginal intercourse with both regular and casual partners.

    The current exploratory study utilized a family strengths framework to identify marital expectations in 39 strong African American heterosexual marriages. Couples reflected on their marital expectations over their 10 or more years of marriage. Three themes emerged through qualitative analysis and the participants' own words were used in the presentation of the themes. African Americans indicated that there was growth in marital expectations over time, with marital expectations often beginning with unrealistic expectations that grew into more realistic expectations as their marriages progressed. Participants also indicated that core expectations in strong African American marriages included open communication, congruent values, and positive treatment of spouse. Finally, participants explained there is an "I" in marriage as they discussed the importance of autonomy within their marital relationships. Results are discussed in association with existing research and theory. © 2016 Family Process Institute.

    Many studies have investigated heterosexuals' prejudices toward nonheterosexuals, yet LGB's prejudices toward heterosexuals remain largely unexplored. Therefore, we sought to determine the threats and opportunities (i.e., affordances) LGB perceive heterosexuals to pose and whether those affordances explain their sexual prejudices toward heterosexuals. Study 1 analyzed LGB's reasons for liking and disliking heterosexuals, which determined whether the threats predicted to be salient for LGB mirrored the affordances they generated. Study 2 measured these perceived affordances and examined the extent to which they drove LGB's prejudices toward heterosexuals. Generally, perceptions of discrimination and unreciprocated sexual interest threats drove anger, physical safety and sexual autonomy threats drove fear, and values threats drove moral disgust toward heterosexuals, although results varied slightly by perceiver and target groups. Goals to alleviate the tensions between heterosexuals and LGB require an understanding of the dynamics between these groups. This research provides preliminary insights into understanding those dynamics. © 2016 by the Society for Personality and Social Psychology, Inc.

    Anecdotal reports of mood disorder following infection with common respiratory viruses with neurotropic potential have been in existence since the last century. Nevertheless, systematic studies on the association between these viruses and mood disorders are lacking. Influenza A, B and coronavirus antibody titers were measured in 257 subjects with recurrent unipolar and bipolar disorder and healthy controls, by SCID. Pearson's χ² tests and logistic regression models were used to analyze associations between seropositivity for coronaviruses, influenza A and B viruses and the following: a) history of recurrent mood disorders b) having attempted suicide in the past c) uni- vs. bi-polarity and d) presence of psychotic symptoms during mood episodes. Seropositivity for influenza A (p=0.004), B (pmood disorders but not with the specific diagnosis of unipolar or bipolar depression. Seropositivity for influenza B was significantly associated with a history of suicide attempt (p=0.001) and history of psychotic symptoms (p=0.005). The design was cross-sectional. Socioeconomic factors, inflammatory markers, and axis II psychopathology were not assessed. The association of seropositivity for influenza and coronaviruses with a history of mood disorders, and influenza B with suicidal behavior require replication in larger longitudinal samples. The need for these studies is additionally supported by the high incidence of these viral infections, the high prevalence of mood disorders, and resilience of suicide epidemics.

    Classifying patients into two subsets of the disease--seronegative RA and seropositive RA--has been the subject of many studies which aim to clarify this phenomenon--without any conclusive or acceptable answer so far. The aim of this prospective study was to establish a scientific comparative analysis between seronegative and seropositive rheumatoid arthritis (RA) regarding some epidemiological and anamnestic characteristics. The studied group consisted of seronegative patients with titers lower than 1:64 as defined by Rose-Waaler test, while the control group consisted of seropositive patients with titers of 1:64 or higher. All patients belonged to 2nd and 3rd functional class according to the ARA criteria, were between 25-60 years of age (Xb=49.96), with disease duration between 1-27 years (Xb=6.41). Education, residence, economic and living conditions did not show any significant statistical difference regarding serostatus. Familial clustering of RA confirmed higher susceptibility in the seropositive group (chi2=7.02; p<0.01). In both subsets banal diseases, psychic and physical trauma, weakness, and numbness of hands and legs dominated, without any statistical differenceregarding serostatus. Some differences between groups regarding sex were noticed, but were not statistically significant, except regarding physical trauma, which was more present in seronegative females (chi2=8.05; p<0.01).

    Full Text Available OBJECTIVE: Blood donors in Brazil have been routinely screened for HTLV-I/II since 1993. A study was performed to estimate the prevalence of HTLV-I/II infection in a low risk population and to better understand determinants associated with seropositivity. METHODS: HTLV-I/II seropositive (n=135, indeterminate (n=167 and seronegative blood donors (n=116 were enrolled in an open prevalence prospective cohort study. A cross-sectional epidemiological study of positive, indeterminate and seronegative HTLV-I/II subjects was conducted to assess behavioral and environmental risk factors for seropositivity. HTLV-I/II serological status was confirmed using enzyme-linked immunosorbent assay (EIA and Western blot (WB. RESULTS: The three groups were not homogeneous. HTLV-I/II seropositivity was associated to past blood transfusion and years of schooling, a marker of socioeconomic status, and use of non-intravenous illegal drugs. CONCLUSIONS: The study results reinforce the importance of continuous monitoring and improvement of blood donor selection process.

    We utilise a clinical case to highlight why exclusion of voltage-gated potassium channel (VGKC)-complex autoantibody testing in serological evaluation of patients may delay or miss the diagnosis. A 68-year-old man presented with increasing involuntary movements consistent with faciobrachial dystonic seizures (FBDS). Initial evaluation demonstrated VGKC antibody seropositivity with leucine-rich glioma-inactivated 1 (LGI1) and contactin-associated protein-like 2 (CASPR2) seronegativity. Aggressive immunotherapy with methylprednisolone and plasmapheresis was started early in the course of his presentation. Following treatment with immunotherapy, the patient demonstrated clinical improvement. Repeat serum evaluation 4 months posthospitalisation remained seropositive for VGKC-complex antibodies, with development of LGI1 autoantibody seropositivity. VGKC-complex and LGI1 antibodies remained positive 12 months posthospitalisation. Our findings suggest that clinical symptoms can predate the detection of the antibody. We conclude that when suspicion for autoimmune encephalitis is high in the setting of VGKC autoantibody positivity, regardless of LGI1 or CASPR2 seropositivity, early immunotherapy and repeat testing should be considered. 2017 BMJ Publishing Group Ltd.

    This study compared gender identity, anticipated future heterosexual romantic involvement, and psychosocial adjustment of children in lesbian and heterosexual families; it was furthermore assessed whether associations between these aspects differed between family types. Data were obtained in the Netherlands from children in 63 lesbian families and 68 heterosexual families. All children were between 8 and 12 years old. Children in lesbian families felt less parental pressure to conform to gender stereotypes, were less likely to experience their own gender as superior and were more likely to be uncertain about future heterosexual romantic involvement. No differences were found on psychosocial adjustment. Gender typicality, gender contentedness and anticipated future heterosexual romantic involvement were significant predictors of psychosocial adjustment in both family types.

  19. Evaluation of Different Parameters of Humoral and Cellular Immune Responses in HIV Serodiscordant Heterosexual Couples: Humoral Response Potentially Implicated in Modulating Transmission Rates

    Full Text Available As the HIV/AIDS pandemic still progresses, understanding the mechanisms governing viral transmission as well as protection from HIV acquisition is fundamental. In this context, cohorts of HIV serodiscordant heterosexual couples (SDC represent a unique tool. The present study was aimed to evaluate specific parameters of innate, cellular and humoral immune responses in SDC. Specifically, plasma levels of cytokines and chemokines, HIV-specific T-cell responses, gp120-specific IgG and IgA antibodies, and HIV-specific antibody-dependent cellular cytotoxicity (ADCC activity were assessed in nine HIV-exposed seronegative individuals (ESN and their corresponding HIV seropositive partners (HIV+-P, in eighteen chronically infected HIV subjects (C, nine chronically infected subjects known to be HIV transmitters (CT and ten healthy HIV− donors (HD. Very low magnitude HIV-specific cellular responses were found in two out of six ESN. Interestingly, HIV+-P had the highest ADCC magnitude, the lowest IgA levels and the highest IgG/IgA ratio, all compared to CT. Positive correlations between CD4+ T-cell counts and both IgG/IgA ratios and %ADCC killing uniquely distinguished HIV+-P. Additionally, evidence of IgA interference with ADCC responses from HIV+-P and CT is provided. These data suggest for the first time a potential role of ADCC and/or gp120-specific IgG/IgA balance in modulating heterosexual transmission. In sum, this study provides key information to understand the host factors that influence viral transmission, which should be considered in both the development of prophylactic vaccines and novel immunotherapies for HIV-1 infection.

    Full Text Available Rickettsiosis is a re-emergent infectious disease without epidemiological surveillance in Colombia. This disease is generally undiagnosed and several deadly outbreaks have been reported in the country in the last decade. The aim of this study is to analyze the eco-epidemiological aspects of rickettsial seropositivity in rural areas of Colombia where outbreaks of the disease were previously reported. A cross-sectional study, which included 597 people living in 246 households from nine hamlets in two municipalities of Colombia, was conducted from November 2015 to January 2016. The survey was conducted to collect sociodemographic and household characteristics (exposure data. Blood samples were collected to determine the rickettsial seropositivity in humans, horses and dogs (IFA, cut-off = 1/128. In addition, infections by rickettsiae were detected in ticks from humans and animals by real-time PCR targeting gltA and ompA genes. Data was analyzed by weighted multilevel clog-log regression model using three levels (person, household and hamlets and rickettsial seropositivity in humans was the main outcome. Overall prevalence of rickettsial seropositivity in humans was 25.62% (95%CI 22.11-29.12. Age in years (PR = 1.01 95%CI 1.01-1.02 and male sex (PR = 1.65 95%CI 1.43-1.90 were risk markers for rickettsial seropositivity.

    Neuromyelitis optica (NMO) is a severe demyelinating inflammatory disorder associated with serum antibodies against aquaporin 4 (AQP4-Ab). A significant number of patients with NMO remain seronegative over time. Long-term observational magnetic resonance imaging (MRI) studies of the CNS in patients with NMO are rare or of limited duration. The objective of this study is to determine long-term MRI characteristics of seropositive and seronegative patients, and assess possible overlap with multiple sclerosis (MS). Clinical and radiological characteristics of 28 patients with NMO at onset and of 17 patients after an average follow-up time of 9 years were recorded. Fifty percent of patients were seropositive for AQP4-Ab. Onset and final brain/spinal MRI scans were retrospectively analysed and compared. Significantly more patients in the seronegative group had brain lesions at onset. Spinal lesions of seropositive patients were longer and showed increased cord swelling at onset MRI scans. After the follow-up time the differences between both groups disappeared. Patients in the seropositive group tended to develop brain lesions over time. No patient fulfilled Barkhof's or McDonald's radiological criteria for MS at onset or over time. Brain MRI features show differences between seropositive and seronegative patients at time of onset in NMO, but differences between groups vanish over time. None of the AQP4-negative patients fulfill radiological MS criteria on a long-term basis, suggesting that seronegative NMO constitutes an independent entity. © 2012 The Author(s) European Journal of Neurology © 2012 EFNS.

    To examine the applicability of psychosexual differentiation theory to the development of sexual orientation, heterosexual (HT) women, HT men, lesbians, and gay men (20 per group) completed a lexical-decision/semantic monitoring task (LD/SM) to assess verbal ability, as well as a Water Level Task (WLT) and two Mental Rotation (MR) Tasks designed to assess spatial ability. All tests have been shown to differentiate HT men and women. Results replicated previously reported sex differences between the HT men and women. Further, gay men performed akin to HT women on the verbal task and the MR tasks, but not in the WLT. Lesbians, however, primarily performed in a sex-typical manner. The dissociation in sex-atypicality between lesbians and gay men is discussed in relation to neurobiological factors related to the development of both sex-dimorphic cognitive ability and sexual orientation.

    Swinging involves consensual mutual involvement in extra-dyadic sex. Jealousy in swinging couples is an interesting topic for social psychological research, because it is a common and acceptable response to a romantic partner's real or imagined infidelity. This qualitative study examined the management of jealousy among four active heterosexual swinging couples living in southern England. Participants highlighted the importance of discussion and negotiation to develop a shared couple identity and shared rules and boundaries that allowed them to manage jealousy so that they could better enjoy swinging. Rather than seeking to eliminate jealousy, swingers may manage their feelings of jealousy in order to increase sexual excitement and arousal. This study adds to our understanding of jealousy among swingers and the broader issue of jealousy in intimate relationships.

    The present study examined partner preferences of homosexual and heterosexual men and woman, focusing on attractiveness and status. Homosexual (N=591 men; M age=28.87 years, SD=10.21; N=249 women; M age=33.36 years, SD=13.12) and heterosexual participants (N=346 men; M age=39.74 years, SD=14.26; N=400 women; M age=35.93 years, SD=13.72) rated the importance of attractiveness and social status of potential partners and then, in a vignette test, expressed their desire to date hypothetical potential partners based on photographs that varied in attractiveness and status-related profiles. With ratings, heterosexual men valued attractiveness the most, followed by homosexual men, heterosexual women, and homosexual women. Heterosexual women rated social status as most important. When status profiles were manipulated and accompanied with photographs of faces, the pattern of differences between homosexuals and heterosexuals supported the self-reported results. Overall, homosexual men and women have similar mate preferences to heterosexual men and women by showing more dating desire for attractive and high social status persons. Compared to attractiveness, status played a smaller role in dating desire.

We analyzed 50 heterosexual and 50 male homosexual films released between August 1, 2005, and July 31, 2006, randomly selected from the distributor of 85% of the heterosexual adult films released each year in the United States. Penile-vaginal intercourse was protected with condoms in 3% of heterosexual scenes. Penile-anal intercourse, common in both heterosexual (42%) and homosexual (80%) scenes, was much less likely to be protected with condoms in heterosexual than in homosexual scenes (10% vs 78%; P film industry, especially the heterosexual industry, is not adhering to state occupational safety regulations.

    Full Text Available Abstract Introduction Concurrent rheumatoid factor seropositivity is occasionally detected in ankylosing spondylitis and often causes confusion in clinical routine. Overlap between various seronegative arthritides is a known but uncommon association. Differentiation of spondyloarthropathy from rheumatoid arthritis is important, since the natural history, complications, treatments and prognosis of the two diseases differ significantly. Case presentation Here, we report the case of a 47-year-old Sri Lankan man who had a long history of intermittent joint pains worsening following a recent episode of self-resolving non-bloody diarrhea. Subsequently, he developed a skin rash suggestive of keratoderma blenorrhagica and circinate balanitis. He had classical radiological evidence of ankylosing spondylosis (previously undiagnosed associated with human leukocyte antigen B27 antigen, but was positive for rheumatoid factor. Conclusions A disease flare of ankylosing spondylitis prompted by a minor diarrheal illness showing well documented features of reactive arthritis is remarkable. The prognostic implications of seropositivity in spondyloarthritis are discussed.

    The aim of this study is to establish a scientific comparative analysis between seronegative and seropositive rheumatoid arthritis (RA), with regard to some clinical characteristics. The studied group consisted of RA seronegative patients with titters lower then 1:64 defined by Rose-Waaler test, while the control group consisted of RA seropositive patients with titters of 1:64 or higher. Examinees all belonged to the 2nd and 3rd functional classes according to ARA criteria, were between 25-60 years of age (Xb = 49.96), with disease duration between 1-27 years (Xbox = 6.41). In the disease onset most frequently affected joints were metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joint of the hands, almost equally represented with regard to sero-status and sex. During the examination seropositive patients showed a higher presence of inflamation of peripheral joints of hand and foot, but only the presence of PIP of the hands was statistically significant (chi2 = 15.63, p < 0.01). Knees, talocrural joints and elbows were more frequently affected in seropositive patients, whereas humeroscapular, coxofemoral and sacroiliacal joints were more frequently affected in seronegative patients, but without significant statistical difference with regard to sero-status. The presence of affected PIP of the hands (chi2 = 9.96, p < 0.01) and knees (chi2 = 4.17, p < 0.05) with regard to sex was statistically significant in seropositive female patients, as well as the presence of atacked PIP of the hands (chi2 = 6.08, p < 0.05), and cervical vertebrae (chi2 = 6.00, p < 0.05) in seropositive male patients. There were some differences between groups with regard to sex in metatarsophalangealjoints (MTP), PIP of the foot, and other joints, but without any statistical significance.

    A group of 11 B27-positive, seropositive patients with rheumatoid arthritis was compared with 11 matched B27-negative seropositive patients. The radiographs of all limb joints, the sacroiliac joints, and the cervical spine were read blindly. Ten patients in each group were radiographed 2-6 times during observation periods of 3-13 years; one patient in each group was only examined once. The prevailing picture of both groups was that of progressive erosive rheumatoid arthritis, although two small differences were found: Erosions of the apophyseal joints of the cervical spine and slight periosteal new bone formation of the shoulder, hip, and knee regions occurred more often in the B27-positive than in the B27-negative group.

    Full Text Available Anti-hepatitis C virus (HCV antibody seropositivity is independently associated with poor prognosis in hemodialysis (HD patients. However, anti-HCV antibody cannot distinguish between patients with active infection and those who have recovered from infection. We therefore aimed in this study to examine the association of HCV core antigen (HCVcAg seropositivity with mortality in HD patients. We first measured serum HCVcAg using an immunoradiometric assay and anti-HCV antibody in 405 patients on regular HD, and followed them for 104 months. There were 82 patients (20.2% who had been positive for anti-HCV antibodies; 57 (69.5% of these were positive for HCVcAg. During the follow-up, 29 patients were excluded, so we tested the association of HCVcAg seropositivity with all-cause, cardiovascular (CV and non-CV mortalities in 376 patients. A total of 209 patients (55.6% had expired during the observational period, 92 out of them due to CV causes. After adjusting for comorbid parameters, HCVcAg was independently associated with overall mortality (HR 1.61, 95% CI 1.05–2.47, p < 0.05. HCV infection was significantly related to liver disease-related mortality. Past HCV infection also contributed to CV mortality (HR 2.63, 95% CI 1.27–5.45, p < 0.01. In contrast, anti-HCV antibody and HCVcAg seropositivities did not associate with infectious disease-related and cancer-related (expect for hepatocellular carcinoma mortality. It follows from these findings that HCVcAg serology is associated with all-cause and CV mortality in HD patients.

    Celiac disease (CD) is a widespread condition triggered by dietary gluten and treated with a lifelong gluten-free diet (GFD); however, inadvertent exposure to gluten can result in episodic symptoms. A previous trial of latiglutenase (clinicaltrials.gov; NCT01917630), an orally administered mixture of two recombinant gluten-specific proteases, was undertaken in symptomatic subjects with persistent injury. The primary endpoint for histologic improvement was not met, presumably due to a trial effect. In this post hoc analysis, we investigated the efficacy of latiglutenase for reducing symptoms in subgroups of the study participants based on their seropositivity. The study involved symptomatic CD patients following a GFD for at least one year prior to randomization. Patients were treated for 12 weeks with latiglutenase or placebo. Of 398 completed patients, 173 (43%) were seropositive at baseline. Symptoms were recorded daily, and weekly symptom scores were compiled. p values were calculated by analysis of covariance. A statistically significant, dose-dependent reduction was detected in the severity and frequency of symptoms in seropositive but not seronegative patients. The severity of abdominal pain and bloating was reduced by 58 and 44%, respectively, in the cohort receiving the highest latiglutenase dose (900 mg, n = 14) relative to placebo (n = 54). Symptom improvement increased from week 6 to week 12. There was also a trend toward greater symptom improvement with greater baseline symptom severity. Seropositive CD patients show symptomatic improvement from latiglutenase taken with meals and would benefit from the availability of this treatment.

  16. Household Socioeconomic and Demographic Correlates of Cryptosporidium Seropositivity in the United States.

    Daniel J Becker

    Full Text Available Cryptosporidium are parasitic protozoa that infect humans, domestic animals, and wildlife globally. In the United States, cryptosporidiosis occurs in an estimated 750,000 persons annually, and is primarily caused by either of the Cryptosporidium parvum genotypes 1 and 2, exposure to which occurs through ingestion of food or water contaminated with oocytes shed from infected hosts. Although most cryptosporidiosis cases are caused by genotype 1 and are of human origin, the zoonotic sources of genotype 2, such as livestock, are increasingly recognized as important for understanding human disease patterns. Social inequality could mediate patterns of human exposure and infection by placing individuals in environments where food or water contamination and livestock contact is high or through reducing the availability of educational and sanitary resources required to avoid exposure.We here analyzed data from the National Health and Nutritional Examination Survey (NHANES between 1999 and 2000, and related seropositivity to Cryptosporidium parvum to correlates of social inequality at the household and individual scale. After accounting for the complex sampling design of NHANES and confounding by individual demographics and household conditions, we found impaired household food adequacy was associated with greater odds of Cryptosporidium seropositivity. Additionally, we identified individuals of non-white race and ethnicity and those born outside the United States as having significantly greater risk than white, domestic-born counterparts. Furthermore, we provide suggestive evidence for direct effects of family wealth on Cryptosporidium seropositivity, in that persons from low-income households and from families close to the poverty threshold had elevated odds of seropositivity relative to those in high-income families and in households far above the poverty line.These results refute assertions that cryptosporidiosis in the United States is independent of

    Full Text Available Background: Transfusion-transmissible infections HIV, HBV, and HCV are among the greatest threats to blood safety for transfusion recipients. Seroprevalence among blood donors is a useful source of information on their prevalence in the community. The present study was undertaken to determine the profile of the seropositive blood donors attending the blood bank at Christian Medical College, Ludhiana, Punjab. Materials and Methods: This was a 3-year cross-sectional study, (1 st January 2008 till 31 st December 2010 whereby the data of the blood donors screened during this time were analyzed. We further studied the epidemiological profile of the seropositive donors. Results: There were a total of 32,829 donations. Seroprevalence of HIV, HBV, and HCV were 0.27%, 1.11% and 1.53%, respectively. Most of them were males (96.76% and were in the age group of 18-30 years. Replacement donors constituted 95.75%. Occupation of seropositive donors included business, various services, and agriculture. There were 89 students who were seropositive. Conclusions: Seroprevalence among blood donors has shown a significant (P value for HIV 0.05, HBV < 0.001, HCV 0.004 decreasing trend over the 3 years. The professional distribution reveals the shift in seroprevalence from the high-risk group to the general population. Introducing pre test and post test counselling in blood banks will identify patients at an earlier stage where treatment would be more effective. The need to shift the burden to voluntary blood donation cannot be overemphasised.

    Equine viral arteritis (EVA), a disease caused by infection with the equine arteritis virus (EAV), is present in many European countries. In Spain, the last confirmed outbreak was reported in 1992 and there is a paucity of seroprevalence studies. The disease has a major impact on the equine breeding industry, which is mainly represented by Spanish Purebred (SP) horses in Spain. To estimate the seroprevalence of EAV in the breeding SP horse population in central Spain and identify potential horse and studfarm level factors associated with seropositivity to EAV. Cross-sectional study. Individual serum samples from 555 SP horses, collected between September 2011 and November 2013 at 35 studfarms, were tested using a commercially available EAV antibody ELISA and seroneutralisation as the World Organisation for Animal Health reference confirmation test for samples with positive and equivocal results. Data on factors putatively associated with seropositivity to EAV were collected via a questionnaire and examined using random effects logistic regression for analysis of clustered data. Equine arteritis virus seroprevalence in the SP breeding population in central Spain standardised for the sex distribution of the reference horse population, was estimated to be 16.8% (95% confidence interval 5.2-28.5%). Increasing numbers of breeding mares on the studfarm and increasing percentage of mares with reproductive problems during the last 12 months were identified as being positively associated with EAV seropositivity. Mares vaccinated against Equine herpesvirus-1 (EHV-1) and/or -4 (EHV-4) were also positively associated with EAV seropositivity. These findings are of importance to ensure appropriate biosecurity measures for studfarms are carried out and may help facilitate the development of an EVA surveillance programme in the SP breeding horse population. © 2015 EVJ Ltd.

    A four-year-old, neutered male, domestic shorthair cat presented witha polyarthropathy. Indirect immunofluorescence assays revealed seropositive results for both feline synctial-forming virus (FeSFV) and feline immunodeficiency virus (FIV). Direct relationships between viral infections and polyarthropathy are not confirmed, however, possible correlations are discussed. Mechanisms of lentivirus infections and polyarthropathy in the cat are reviewed in order to theorize a potential relationship among these disease processes

    Full Text Available Abstract MicroRNAs (miRNAs play diverse roles in regulating cellular and developmental functions. We have profiled the miRNA expression in peripheral blood mononuclear cells from 36 HIV-1 seropositive individuals and 12 normal controls. The HIV-1-positive individuals were categorized operationally into four classes based on their CD4+ T-cell counts and their viral loads. We report that specific miRNA signatures can be observed for each of the four classes.

    Full Text Available The aim of this work was to analyze the neuron morphology and morphometry of cervical, thoracic and lumbar areas of nonsymptomatic seropositive dogs’ spinal cord for toxoplasmosis. Twenty indefinite-breed adult dogs were used; ten dogs were healthy, with negative serology for toxoplasmosis, and were used as the control group (group 1, and ten dogs were nonsymptomatic but seropositive for toxoplasmosis (group 2. After the microtomy, with interval of 100 micrometers (µm, the histological 5-µm-thick cuts were dyed by hematoxylin-eosin and Masson's trichrome techniques. The glass slides were analyzed under light microscope to examine the neuron morphology. The parameters considered for the morphometric analysis were area, perimeter, maximum diameter, minimum diameter and shape factor of cytoplasm and nucleus of neuron. The results were statistically analyzed by Student’s t test at 5% probability level. The morphological characteristics between the two groups were similar and according to literature. The morphometric results showed that there were changes in neurons size and structure, and increase and loss of star shape were noticed in seropositive animals. The results suggest that the neurons of these dogs, yet nonsymptomatic, can have lost their conductor function.

    Full Text Available HIV-seropositive patients show high incidence of coronary heart disease and oxidative stress has been described as relevant key in atherosclerosis development. The aim of this study was to assess the effect of omega 3 fatty acids on different markers of oxidative stress in HIV-seropositive patients. We performed a randomized parallel controlled clinical trial in The Instituto Mexicano del Seguro Social, a public health hospital. 70 HIV-seropositive patients aged 20 to 55 on clinical score A1, A2, B1 or B2 receiving highly active antiretroviral therapy (HAART were studied. They were randomly assigned to receive omega 3 fatty acids 2.4 g (Zonelabs, Marblehead MA or placebo for 6 months. At baseline and at the end of the study, anthropometric measurements, lipid profile, glucose and stress oxidative levels [nitric oxide catabolites, lipoperoxides (malondialdehyde plus 4-hydroxialkenals, and glutathione] were evaluated. Principal HAART therapy was EFV/TDF/FTC (55% and AZT/3TC/EFV (15% without difference between groups. Treatment with omega 3 fatty acids as compared with placebo decreased triglycerides (-0.32 vs. 0.54 mmol/L; p = 0.04, but oxidative stress markers were not different between groups.

    The present study aimed to investigate the possible association of Toxoplasma gondii and Toxocara spp. infections with cryptogenic epilepsy in children. The study was carried out between June 2014 and March 2015. Total 90 children (40 with cryptogenic epilepsy, 30 with non-cryptogenic epilepsy, and 20 healthy control children) were evaluated to determine the anti-Toxocara and anti-T. gondii IgG seropositivity using ELISA kits. Epileptic cases were selected from those attending the pediatrics outpatient clinic of Benha University Hospital, Pediatrics Neurology Unit, and from Benha Specialized Hospital of children. The results showed that the level of anti-T. gondii IgG seropositivity was significantly higher among children with cryptogenic epilepsy (20%) than among children with non-cryptogenic children (0%). In healthy controls (10%), there was no association between toxocariasis seropositivity and cryptogenic epilepsy (only 5.7%; 4 out of 70 cases) among cases and 10% (2 out of 20) among controls. Among toxocariasis IgG positive cases, 3 (7.5%) were cryptogenic, and only 1 (3.3%) was non-cryptogenic. These statistically significant results support the association between T. gondii infection and cryptogenic epilepsy while deny this association with toxocariasis.

    Feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV) are among the most important feline infectious diseases worldwide. This retrospective study investigated survival times and effects of selected predictor factors on survival time in a population of owned pet cats in Northern Italy testing positive for the presence of FIV antibodies and FeLV antigen. One hundred and three retrovirus-seropositive cats, 53 FIV-seropositive cats, 40 FeLV-seropositive cats, and 10 FIV+FeLV-seropositive cats were included in the study. A population of 103 retrovirus-seronegative age and sex-matched cats was selected. Survival time was calculated and compared between retrovirus-seronegative, FIV, FeLV and FIV+FeLV-seropositive cats using Kaplan-Meier survival analysis. Cox proportional-hazards regression analysis was used to study the effect of selected predictor factors (male gender, peripheral blood cytopenia as reduced red blood cells - RBC- count, leukopenia, neutropenia and lymphopenia, hypercreatininemia and reduced albumin to globulin ratio) on survival time in retrovirus-seropositive populations. Median survival times for seronegative cats, FIV, FeLV and FIV+FeLV-seropositive cats were 3960, 2040, 714 and 77days, respectively. Compared to retrovirus-seronegative cats median survival time was significantly lower (P<0.000) in FeLV and FIV+FeLV-seropositive cats. Median survival time in FeLV and FIV+FeLV-seropositive cats was also significant lower (P<0.000) when compared to FIV-seropositive cats. Hazard ratio of death in FeLV and FIV+FeLV-seropositive cats being respectively 3.4 and 7.4 times higher, in comparison to seronegative cats and 2.3 and 4.8 times higher in FeLV and FIV+FeLV-seropositive cats as compared to FIV-seropositive cats. A Cox proportional-hazards regression analysis showed that FIV and FeLV-seropositive cats with reduced RBC counts at time of diagnosis of seropositivity had significantly shorter survival times when compared to FIV and FeLV-seropositive

    Previous studies have revealed different human leukocyte antigen (HLA) associations in multiple sclerosis (MS) and neuromyelitis optica (NMO), further discriminating these two demyelinating pathological conditions. In worldwide analyses, NMO and opticospinal MS are represented at higher proportions among demyelinating conditions in African, East-Asian and Latin American populations. There are currently no data regarding the prevalence of NMO in Middle East Muslims. The population in Israel is diverse in many ways, and includes subpopulations, based on religion and ethnicity; some exhibit genetic homogeneity. In Israel, the incidence of MS is lower in the Muslim population than the Jewish population and Muslims carry different allele frequency distribution of HLA haplotypes. To evaluate the occurrence of anti-AQP4 seropositivity in the Israeli Muslim population among patients with central nervous system (CNS) demyelinating conditions; and to identify the HLA DR and DQ profiles of Muslim Arab Israeli patients with NMO spectrum of diseases (NMOSD). The prevalence of anti-AQP4 seropositivity was analyzed in 342 samples, obtained from patients with various CNS demyelinating conditions and in a validation set of 310 samples. HLA class II alleles (HLA-DRB1 and DQB1) were examined in DNA samples from 35 Israeli Muslim Arabs NMO patients and compared to available data from 74 Israeli Muslim controls. Our data reveal a significantly increased prevalence of anti-AQP4 seropositivity, indicative of NMOSD, in Muslim Arab Israeli patients with initial diagnosis of a CNS demyelinating syndrome. In this population, there was a positive association with the HLA-DRB1*04:04 and HLA-DRB1*10:01 alleles (p=0.03), and a strong negative association with the HLA-DRB1*07 and HLA-DQB1*02:02 alleles (p=0.003, p=0.002). Our findings indicate a possibly increased prevalence of NMOSD in Muslim Arabs in Israel with distinct (positive and negative) HLA associations. Further studies in patients with

    Research has consistently found that school students who do not identify as self-declared completely heterosexual are at increased risk of victimization by bullying from peers. This study examined heterosexual and nonheterosexual university students' involvement in both traditional and cyber forms of bullying, as either bullies or victims. Five hundred twenty-eight first-year university students (M=19.52 years old) were surveyed about their sexual orientation and their bullying experiences over the previous 12 months. The results showed that nonheterosexual young people reported higher levels of involvement in traditional bullying, both as victims and perpetrators, in comparison to heterosexual students. In contrast, cyberbullying trends were generally found to be similar for heterosexual and nonheterosexual young people. Gender differences were also found. The implications of these results are discussed in terms of intervention and prevention of the victimization of nonheterosexual university students.

    Low levels of life satisfaction have been linked to low self-esteem and loneliness, but this association has never been tested directly in LGB (lesbian/gay/bisexual) populations. We compared 275 Chinese LGB adults to 275 demographic-matched Chinese heterosexual controls on life satisfaction, self-esteem, and loneliness. LGB adults reported lower levels of self-esteem and higher levels of loneliness than heterosexuals, but similar levels of overall life satisfaction. Self-esteem partially mediated (but did not moderate) the relationship between loneliness and life satisfaction in both groups. Hierarchical regressions indicated that demographic variables, loneliness, and self-esteem can predict life satisfaction in both LGB and heterosexual adults, but explained more variance of life satisfaction in the LGB group. Thus self-esteem and loneliness play a more important role in life satisfaction for LGB rather than heterosexual Chinese adults.

    Equine protozoal myeloencephalitis is a commonly diagnosed neurological disease of horses in North America and is caused by infection with Sarcocystis neurona or Neospora hughesi. The aim of this study was to compare prevalence factors among horses seropositive or seronegative to N. hughesi and/or S. neurona. A total of 3123 submissions were included in the study, with horses originating from 49 States. Thirty-eight animals from 21 States tested seropositive for N. hughesi only, 840 horses from 40 States were seropositive for S. neurona only, 25 horses from 14 States were seropositive for both protozoa, and 2220 horses from 49 States tested seronegative for both parasites. Significant associations were found between geographical location (State), month of submission, breed and serological status. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Objective: To analyze the influence of growing experience on non-heterosexual orientation among male college students. Methods: From October to November in 2015, a total of 2 535 male students from 96 classes in 14 colleges/departments were recruited from two colleges that participated in the experimental work of AIDS prevention by cluster random sampling method. A structured questionnaire was administered in this study, including general demographic information, growing experience and Kinsey scale (to evaluate sexual orientation). Out of 2 500 questionnaires distributed in this study, 2 332 effective copies were withdrew, with the effective rate at 93.3%. Chi square test was used to analyze the differences of non-heterosexual orientation among the individuals with different social demographic characteristics. Multivariate logistic regression model was used to analyze the influencing factors of non-heterosexual orientation. Results: Among the 2 332 individuals, the proportion of self-reported non-heterosexual was 6.2% (144).The proportions of male students who identify as non-heterosexual from freshman to junior year were 5.2%(63/1216),6.9%(65/941),11.7%(13/111) and 4.7%(3/64), respectively (χ(2)=9.06, P= 0.029). Compared with the individuals of very good relationship with parents, those with bad relationship ( OR= 3.3, 95 %CI: 1.7-6.5) and general relationship ( OR= 1.7, 95 %CI: 1.0-2.9) with parents had a higher risk of non-heterosexual orientation, respectively. Those encountered sexual assault had a higher risk of non-heterosexual orientation than those without encountered sexual assault ( OR= 5.9, 95 %CI: 3.2-10.9). Conclusions: This study reported a high proportion of self-reported non-heterosexual among college male students in Nanjing, and highlighted the importance of targeting students with poor parental relationships and who subjected to sexually abused.

    Full Text Available Cytomegalovirus (CMV is the most frequent cause of congenital infection. The objective of this study was to evaluate predictive factors for CMV seronegativity in a cohort of pregnant women in Paris, France.Pregnant women enrolled in a prospective cohort during the 2009 A/H1N1 pandemic were tested for CMV IgG antibodies. Variables collected were age, geographic origin, lifestyle, work characteristics, socioeconomic status, gravidity, parity and number of children at home. A multivariate logistic regression model was used to identify independent predictive factors for CMV seropositivity.Among the 826 women enrolled, 389 (47.1% were primiparous, and 552 (67.1% had Metropolitan France as a geographic origin. Out of these, 355 (i.e. 57.0%, 95% confidence interval (CI: [53.6%-60.4%] were CMV seropositive: 43.7% (95% CI:[39.5%-47.9%] in those whose geographic origin was Metropolitan France and 84.1% in those with other origins (95% CI:[79.2%-88.3%]. Determinants associated with CMV seropositivity in a multivariate logistic regression model were: (i geographic origin (p<0.001(compared with Metropolitan France, geographic origins of Africa adjusted odds ratio (aOR 21.2, 95% CI:[9.7-46.5], French overseas departments and territories and other origin, aOR 7.5, 95% CI:[3.9-14.6], and Europe or Asia, aOR 2.2, 95% CI: [1.3-3.7]; and (ii gravidity (p = 0.019, (compared with gravidity = 1, if gravidity≥3, aOR = 1.5, 95% CI: [1.1-2.2]; if gravidity = 2, aOR = 1.0, 95% CI: [0.7-1.4]. Work characteristics and socioeconomic status were not independently associated with CMV seropositivity.In this cohort of pregnant women, a geographic origin of Metropolitan France and a low gravidity were predictive factors for CMV low seropositivity. Such women are therefore the likely target population for prevention of CMV infection during pregnancy in France.

    The current study tested a conceptual model based on social-cognitive theory (Bandura, 1986), highlighting the influence of attitudes toward sexual minority individuals, training hours, affirmative counseling self-efficacy, and beliefs about affirmative practice on therapist engagement in lesbian and gay affirmative practice. We recruited via the Internet 443 heterosexual psychologists (n = 270), clinical social workers (n = 110), and marriage and family therapists (n = 63) residing in various parts of the United States. The majority of participants identified as female (70%) and White (88%). A path analysis indicated that beliefs and affirmative counseling self-efficacy mediated associations between attitudes and therapist engagement in affirmative practice. Furthermore, self-efficacy mediated the relation between training hours and engagement in affirmative practice. Results suggest that more affirmative attitudes are linked with higher levels of affirmative counseling self-efficacy and more positive beliefs, which in turn positively influences therapist engagement in affirmative practice. Additionally, more hours of training influence affirmative counseling self-efficacy, which in turn correlates with higher levels of therapist engagement in affirmative practice. The discussion includes implications for affirmative practice training. (c) 2015 APA, all rights reserved).

    Little research has examined the school experiences of lesbian/gay (LG) parent families or adoptive parent families. The current exploratory study examined the experiences of 79 lesbian, 75 gay male, and 112 heterosexual adoptive parents of preschool-age children with respect to their (a) level of disclosure regarding their LG parent and adoptive family status at their children's schools; (b) perceived challenges in navigating the preschool environment and advocating on behalf of their children and families; and (c) recommendations to teachers and schools about how to create affirming school environments with respect to family structure, adoption, and race/ethnicity. Findings revealed that the majority of parents were open about their LG and adoptive family status, and had not encountered challenges related to family diversity. Those parents who did experience challenges tended to describe implicit forms of marginalization, such as insensitive language and school assignments. Recommendations for teachers included discussing and reading books about diverse families, tailoring assignments to meet the needs of diverse families, and offering school community-building activities and events to help bridge differences across families.

    Knowledge about how gender shapes intimacy is dominated by a heteronormative focus on relationships involving a man and a woman. In this study, the authors shifted the focus to consider gendered meanings and experiences of intimacy in same-sex and different-sex relationships. They merged the gender-as-relational perspective-that gender is co-constructed and enacted within relationships-with theoretical perspectives on emotion work and intimacy to frame an analysis of in-depth interviews with 15 lesbian, 15 gay, and 20 heterosexual couples. They found that emotion work directed toward minimizing and maintaining boundaries between partners is key to understanding intimacy in long-term relationships. Moreover, these dynamics, including the type and division of emotion work, vary for men and women depending on whether they are in a same-sex or different-sex relationship. These findings push thinking about diversity in long-term relationships beyond a focus on gender difference and toward gendered relational contexts.

    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.

    Research on heterosexual allies has focused on heterosexual identity development models and pathways to ally activism. The positive aspects or positive experiences of identifying as an ally to lesbian, gay, bisexual, and transgender (LGBT) identified individuals and communities have received little attention. Using an online survey of participants recruited from LGBT ally related social media, we collected open-ended responses to a question about the positive aspects of self-identifying as a heterosexual ally. A final analytic sample of 292 self-identified male and female heterosexual adults (age 18-71, M = 33.47, SD = 13.32) provided responses that generated 8 themes. Positive aspects of being a heterosexual ally were: (a) increased knowledge and awareness, (b) upholding values of justice, (c) beneficial individual relationships, (d) community belonging, (e) educating others, (f) being a role model, (g) using social privilege, and (h) speaking out and taking a stand. The findings suggest that being a heterosexual ally is rewarding and may enhance individual well-being. These findings provide information that may contribute to effective ally development efforts.

  19. Dogma disputed: potential endemic heterosexual transmission of human immunodeficiency virus in Australia.

    The concept of tertiary sexual transmission of human immunodeficiency virus (HIV) has been central to government efforts to communicate notions of risk to heterosexuals in Australia. Data on heterosexually transmitted acquired immune deficiency syndrome (AIDS) and HIV for Australia are reviewed with emphasis given to the probability of misclassification bias in the heterosexually acquired and 'other/undetermined' categories. Tertiary cases are almost certainly rare in Australia, with little evidence of any increase in their incidence since the first cases were recorded. Three factors (low probability of exposure, the infectivity of HIV and a comparatively low rate of sexual partner change) make it improbable that Australian heterosexuals with no risk factors will experience endemic HIV infection, with a caveat to this conclusion lying in the potential of Australian sex tourism to Southeast Asia for introducing HIV into the Australian heterosexual population. Four hegemonic factors which have acted to suppress any serious debate of the notion that HIV in Australia is unlikely to become endemic among heterosexuals are discussed: the political 'democratization' of risk inspired by concerns that gay men should not be further vilified as a victim group; the preventive imperative; a reluctance among health educators to question the very foundations of the message they are employed to deliver; and a reluctance to curtail 'Trojan horse' benefits to sexually transmissible disease prevention engendered by HIV education promoting safe sex messages.

    The aim of the study was to determine the time to, and risk factors for, triple-class virological failure (TCVF) across age groups for children and adolescents with perinatally acquired HIV infection and older adolescents and adults with heterosexually acquired HIV infection. We analysed individual patient data from cohorts in the Collaboration of Observational HIV Epidemiological Research Europe (COHERE). A total of 5972 participants starting antiretroviral therapy (ART) from 1998, aged 500 HIV-1 RNA copies/mL despite ≥ 4 months of use. TCVF was defined as cumulative failure of two NRTIs, an NNRTI and a bPI. The median number of weeks between diagnosis and the start of ART was higher in participants with perinatal HIV infection compared with participants with heterosexually acquired HIV infection overall [17 (interquartile range (IQR) 4-111) vs. 8 (IQR 2-38) weeks, respectively], and highest in perinatally infected participants aged 10-14 years [49 (IQR 9-267) weeks]. The cumulative proportion with TCVF 5 years after starting ART was 9.6% [95% confidence interval (CI) 7.0-12.3%] in participants with perinatally acquired infection and 4.7% (95% CI 3.9-5.5%) in participants with heterosexually acquired infection, and highest in perinatally infected participants aged 10-14 years when starting ART (27.7%; 95% CI 13.2-42.1%). Across all participants, significant predictors of TCVF were those with perinatal HIV aged 10-14 years, African origin, pre-ART AIDS, NNRTI-based initial regimens, higher pre-ART viral load and lower pre-ART CD4. The results suggest a beneficial effect of starting ART before adolescence, and starting young people on boosted PIs, to maximize treatment response during this transitional stage of development. © 2016 The Authors.

    Full Text Available Background. Rheumatoid arthritis (RA, met in the literature also as chronic evolving polyarthritis, is a chronic inflammatory disease, which typically involves the small and medium joints, with a symmetric distribution. Clinical studies shown that a proportion of patients with RA, without measurable rheumatoid factors are a distinct entity from those patients with seropositive RA. Around one third of patients with RA are seronegative for those two serological markers, the rheumatoid factors (RF and anti-citrullinated peptide antibodies (Anti-CCP. Hands are the most frequently affected in both seropositive and seronegative RA and the first joints involved in the inflammatory process are the metacarpo-phalangeal joints, IFP joints and the radiocarpian joint. The big joints become later symptomatic, after the small joints are affected. Materials and methods: 66 patients files and the personal records of the patients consecutively admitted in the Rheumatology Department of the Clinical Emergency County Hospital Constanta. Patients from county Constanta were included in the study, with diagnosis of rheumatoid arthritis (diagnosis confirmed at least 2 years ago, including both forms (seropositive and seronegative of the disease. The complete clinical exam was done for the patients included in the study, following the identification of the active joint disease. The mechanical status of the joint was observed by a single evaluator for each of those 66 patients with RA, with special focus on the presence of the deformities / ankyloses of the hands joints. Therefore, there were evaluated: the mobility (the number of the joints with limited movements, deformities, ankyloses (the number of the joints without mobility. The joint mobility was assessed by counting the hand joints with limited movements and the worsening of the prehension function. The presence of the following hand deformities was followed: fingers in “swan neck”, “fusiform fingers

    HIV-2 is endemic in West Africa. There is a lack of evidence-based guidelines on the diagnosis, management and antiretroviral therapy (ART) for HIV-2 or HIV-1/HIV-2 dual infections. Because of these issues, we designed a West African collaborative cohort for HIV-2 infection within the framework of the International epidemiological Databases to Evaluate AIDS (IeDEA). We collected data on all HIV-2 and HIV-1/HIV-2 dually seropositive patients (both ARV-naive and starting ART) and followed-up in clinical centres in the IeDEA-WA network including a total of 13 clinics in five countries: Benin, Burkina-Faso Côte d'Ivoire, Mali, and Senegal, in the West Africa region. Data was merged for 1,754 patients (56% female), including 1,021 HIV-2 infected patients (551 on ART) and 733 dually seropositive for both HIV-1 and HIV 2 (463 on ART). At ART initiation, the median age of HIV-2 patients was 45.3 years, IQR: (38.3-51.7) and 42.4 years, IQR (37.0-47.3) for dually seropositive patients (p = 0.048). Overall, 16.7% of HIV-2 patients on ART had an advanced clinical stage (WHO IV or CDC-C). The median CD4 count at the ART initiation is 166 cells/mm(3), IQR (83-247) among HIV-2 infected patients and 146 cells/mm(3), IQR (55-249) among dually seropositive patients. Overall, in ART-treated patients, the CD4 count increased 126 cells/mm(3) after 24 months on ART for HIV-2 patients and 169 cells/mm(3) for dually seropositive patients. Of 551 HIV-2 patients on ART, 5.8% died and 10.2% were lost to follow-up during the median time on ART of 2.4 years, IQR (0.7-4.3). This large multi-country study of HIV-2 and HIV-1/HIV-2 dual infection in West Africa suggests that routine clinical care is less than optimal and that management and treatment of HIV-2 could be further informed by ongoing studies and randomized clinical trials in this population.

    Gastrointestinal and urinary tract pathogenic infections are aggravating the incidence and progression of the Human Immunodeficiency Virus (HIV) infection into Acquired Immune Deficiency Syndrome (AIDS) more especially in the developing countries. This study was conducted to assess the common gastrointestinal and urinary infections among HIV/AIDS patients at the Komfo Anokye Teaching Hospital (KATH) in Ghana between April and December 2008. This work reports on gastrointestinal and urinary tract pathogenic infections among 500 HIV seropositive and 300 HIV seronegative patients. There was a 35% (175/500) prevalence of intestinal parasites among HIV seropositive patients compared to 4.3% (13/300) in HIV seronegative patients. Giardia lamblia and Cryptosporidium accounted for 19% (95/500) and 14% (70/500) respectively, while Schistosoma mansoni, Strongyloides stercoralis and hookworm together accounted for 2% (10/500) of intestinal parasitic infections among the HIV seropositive patients. There was no significant difference (p > 0.05) in urinary parasitic infection between HIV seropositive 1% (2/500) and seronegative patients 0.7% (2/300). Most, 60 (86%) out of 70, of the urinary tract infection among the HIV seropositive patients was due to bacteria with E. coli being the most predominant isolate, 28 (47%) out of 60. There was no significant difference in infections based on age and gender. G. lamblia and Cryptosporidium were the most common gastrointestinal parasites detected while bacteria accounted for majority of the urinary tract infections among the HIV seropositive patients at the hospital.

    This study explored the sexual double standard (SDS) (in which males are afforded more freedom and power than females in heterosexual interactions) in African American mothers' sexual messages to sons and daughters. We used a convenience sample of 129 African American adolescents, aged 14 to 17 years, and their mothers who reported SDS attitudes. Qualitative analyses revealed gender differences based on an SDS in mothers' sexual risk reduction socialization. Mothers typically took a proactive approach with sons and a neutral or prohibitive approach with daughters. Findings provide directions for socially relevant programs for African American parents, schools, and communities.

    Full Text Available Abstract Background Since African-Americans have twice the prevalence of cytomegalovirus (CMV infections as age-matched Caucasians we sought to determine the ages and possible sources of infection of African-American children. Methods Subjects were 157 African-American healthy children and adolescents and their 113 household adults in Richmond VA. Families completed a questionnaire, provided saliva for antibody testing, and adolescents were interviewed regarding sexual activity. Results Regardless of age CMV seropositivity was not associated with gender, breast feeding, health insurance, sexual activity, or household income, education, or size. In the final regression model, prior CMV infection in adults was over two-fold higher than in children (chi-square = 18.8, p Conclusion We observed that African-American children had CMV seroprevalence rates by age 20 years at less than one-half of that of their adult mothers and caregivers. Sibling-to-sibling transmission was a likely source of CMV infections for the children. The next generation of African-American women may be highly susceptible to a primary CMV infection during pregnancy and may benefit from a CMV vaccine.

    Parallel bodies of research have described the diverse and complex ways that men understand and construct their masculine identities (often termed "masculinities") and, separately, how adherence to traditional notions of masculinity places men at risk for negative sexual and health outcomes. The goal of this analysis was to bring together these two streams of inquiry. Using data from a national, online sample of 555 heterosexually active young men, we employed latent class analysis (LCA) to detect patterns of masculine identities based on men's endorsement of behavioral and attitudinal indicators of "dominant" masculinity, including sexual attitudes and behaviors. LCA identified four conceptually distinct masculine identity profiles. Two groups, termed the Normative and Normative/Male Activities groups, respectively, constituted 88 % of the sample and were characterized by low levels of adherence to attitudes, sexual scripts, and behaviors consistent with "dominant" masculinity, but differed in their levels of engagement in male-oriented activities (e.g., sports teams). Only eight percent of the sample comprised a masculinity profile consistent with "traditional" ideas about masculinity; this group was labeled Misogynistic because of high levels of sexual assault and violence toward female partners. The remaining four percent constituted a Sex-Focused group, characterized by high numbers of sexual partners, but relatively low endorsement of other indicators of traditional masculinity. Follow-up analyses showed a small number of differences across groups on sexual and substance use health indicators. Findings have implications for sexual and behavioral health interventions and suggest that very few young men embody or endorse rigidly traditional forms of masculinity.

    Researchers have been investigating similarities of and differences between homosexuals and heterosexuals for past few decades. Several studies have shown that in the particular domain (e.g., spatial ability), male homosexuals would resemble female heterosexuals better than male heterosexuals. Executive function, however, has received more attention than social cognition in this line of research. This study focuses on theory of mind and empathy as two important components of social cognition in male homosexuals (N=14), male heterosexuals (N=15) and female heterosexuals (N=14). Applying Reading the Mind in the Eyes test and the Empathy Quotient, no significant difference between groups was identified. This study suggests that similarities of male homosexuals and female heterosexuals may be confined to executive function and not extended to some social cognition abilities like theory of mind or empathy.

  9. Reactive, anxious and possessive forms of jealousy and their relation to relationship quality among heterosexuals and homosexuals.

    The present study examined the relationship between relational quality and three different types of jealousy-reactive, anxious and possessive jealousy. The sample consisted of 76 gay men, 79 lesbians, 70 heterosexual women and 70 heterosexual men. Findings show that different types of jealousy affect relationship quality differently and do so differently for homosexuals and heterosexuals. Among heterosexuals and especially gay men--but not among lesbians--anxious jealousy was negatively related to relationship quality. In contrast, among heterosexuals--but not among gay men or lesbians--reactive jealousy was positively related to relationship quality. The present study shows that distinguishing between different types of jealousy is necessary to entangle the diverse effects of jealousy on the quality of homosexual and heterosexual relationships.

  10. Implicit sexual attitude of heterosexual, gay and bisexual individuals: disentangling the contribution of specific associations to the overall measure.

    Directory of Open Access Journals (Sweden)

    Pasquale Anselmi

    Full Text Available The article aims to measure implicit sexual attitude in heterosexual, gay and bisexual individuals. A Many-Facet Rasch Measurement analysis was used to disentangle the contribution of specific associations to the overall IAT measure. A preference for heterosexuals relative to homosexuals is observed in heterosexual respondents, driven most by associating positive attributes with heterosexuals rather than negative attributes with homosexuals. Differently, neither the negative nor the positive evaluation of any of the target groups play a prominent role in driving the preference for homosexuals observed in gay respondents. A preference for heterosexuals relative to homosexuals is observed in bisexual respondents, that results most from ascribing negative attributes to homosexuals rather than positive attributes to heterosexuals. The results are consistent with the expression of the need for achieving a positive self-image and with the influence of shared social norms concerning sexuality.

    One hypothesis derived from evolutionary perspectives is that men are more upset than women by sexual infidelity and women are more upset than men by emotional infidelity. The proposed explanation is that men, in contrast to women, face the risk of unwittingly investing in genetically unrelated offspring. Most studies, however, have relied on small college or community samples of heterosexual participants. We examined upset over sexual versus emotional jealousy among 63,894 gay, lesbian, bisexual, and heterosexual participants. Participants imagined which would upset them more: their partners having sex with someone else (but not falling in love with them) or their partners falling in love with someone else (but not having sex with them). Consistent with this evolutionary perspective, heterosexual men were more likely than heterosexual women to be upset by sexual infidelity (54 vs. 35 %) and less likely than heterosexual women to be upset by emotional infidelity (46 vs. 65 %). This gender difference emerged across age groups, income levels, history of being cheated on, history of being unfaithful, relationship type, and length. The gender difference, however, was limited to heterosexual participants. Bisexual men and women did not differ significantly from each other in upset over sexual infidelity (30 vs. 27 %), regardless of whether they were currently dating a man (35 vs. 29 %) or woman (28 vs. 20 %). Gay men and lesbian women also did not differ (32 vs. 34 %). The findings present strong evidence that a gender difference exists in a broad sample of U.S. adults, but only among heterosexuals.

    2013-01-01

    Uganda's Anti-Homosexuality Bill of 2009 aimed at protecting the cherished culture of the people against emergent threats to the traditional heterosexual family. The Bill's justification, however, lay in myopic imaginings of a homogenous African-ness and pedestrian oblivion to pluralities within African sexualities. This paper revisits the debate that homosexuality is 'un-African'. Rhetoric analysis of the Anti-Homosexuality Bill exposes how dominant discourses of law, medicine, religion, geography and culture reinforce the view that homosexuality is foreign to Africa. Based on ethnography in contemporary Uganda, I explore how self-identified same-sex-loving individuals simultaneously claim their African-ness and their homosexuality. Their strategies include ethnic belonging, membership to kinship structures, making connections with pre-colonial histories of homosexuality, civic participation in democratic processes, national identity, organising of lesbian, gay, bisexual, transgender, intersex and questioning support groups, language and nomenclature, visibility and voice in local communal activities, solidarity and adherence to cultural rituals. In present-day Uganda, same-sex-loving men, women and transgender people variously assert their African-ness.

    Background Q fever is an occupational risk for veterinarians, however little is known about the risk for veterinary medicine students. This study aimed to assess the seroprevalence of Coxiella burnetii among veterinary medicine students and to identify associated risk factors. Methods A cross-sectional study with questionnaire and blood sample collection was performed among all veterinary medicine students studying in the Netherlands in 2006. Serum samples (n = 674), representative of all study years and study directions, were analyzed for C. burnetii IgG and IgM phase I and II antibodies with an immunofluorescence assay (IFA). Seropositivity was defined as IgG phase I and/or II titer of 1∶32 and above. Results Of the veterinary medicine students 126 (18.7%) had IgG antibodies against C. burnetii. Seropositivity associated risk factors identified were the study direction ‘farm animals’ (Odds Ratio (OR) 3.27 [95% CI 2.14–5.02]), advanced year of study (OR year 6: 2.31 [1.22–4.39] OR year 3–5 1.83 [1.07–3.10]) having had a zoonosis during the study (OR 1.74 [1.07–2.82]) and ever lived on a ruminant farm (OR 2.73 [1.59–4.67]). Stratified analysis revealed study direction ‘farm animals’ to be a study-related risk factor apart from ever living on a farm. In addition we identified a clear dose-response relation for the number of years lived on a farm with C. burnetii seropositivity. Conclusions C. burnetii seroprevalence is considerable among veterinary medicine students and study related risk factors were identified. This indicates Q fever as an occupational risk for veterinary medicine students. PMID:22363803

    Full Text Available Toxoplasma gondii is a zoonotic intracellular protozoan parasite of worldwide distribution that infects many species of warm-blooded animals, including birds. To date, there is scant information about the seropositivity of T. gondii and the risk factors associated with T. gondii infection in wild bird populations. In the present study, T. gondii infection was evaluated on sera obtained from 1079 wild birds belonging to 56 species (including Falconiformes (n=610, Strigiformes (n=260, Ciconiiformes (n=156, Gruiformes (n=21, and other orders (n=32, from different areas of Spain. Antibodies to T. gondii (modified agglutination test, MAT titer ≥1:25 were found in 282 (26.1%, IC(95%:23.5-28.7 of the 1079 birds. This study constitute the first extensive survey in wild birds species in Spain and reports for the first time T. gondii antibodies in the griffon vulture (Gyps fulvus, short-toed snake-eagle (Circaetus gallicus, Bonelli's eagle (Aquila fasciata, golden eagle (Aquila chrysaetos, bearded vulture (Gypaetus barbatus, osprey (Pandion haliaetus, Montagu's harrier (Circus pygargus, Western marsh-harrier (Circus aeruginosus, peregrine falcon (Falco peregrinus, long-eared owl (Asio otus, common scops owl (Otus scops, Eurasian spoonbill (Platalea leucorodia, white stork (Ciconia ciconia, grey heron (Ardea cinerea, common moorhen (Gallinula chloropus; in the International Union for Conservation of Nature (IUCN "vulnerable" Spanish imperial eagle (Aquila adalberti, lesser kestrel (Falco naumanni and great bustard (Otis tarda; and in the IUCN "near threatened" red kite (Milvus milvus. The highest seropositivity by species was observed in the Eurasian eagle owl (Bubo bubo (68.1%, 98 of 144. The main risk factors associated with T. gondii seropositivity in wild birds were age and diet, with the highest exposure in older animals and in carnivorous wild birds. The results showed that T. gondii infection is widespread and can be at a high level in many wild

    Full Text Available Abstract Background Determinants of intrafamilial HCV transmission are still being debated. The aim of this study is to investigate the correlates of HCV seropositivity among familial contacts of HCV positive patients in Italy. Methods A cross-sectional study was conducted with 175 HCV positive patients (index cases, recruited from Policlinico Gemelli in Rome as well as other hospitals in Central Italy between 1995 and 2000 (40% female, mean age 57 ± 15.2 years, and 259 familial contacts. Differences in proportions of qualitative variables were tested with non-parametric tests (χ2, Yates correction, Fisher exact test, and a p value Results Seropositivity for HCV was found in 8.9% of the contacts. From the univariate analysis, risk factors significantly associated to HCV positivity in the contacts were: intravenous drug addiction (p = 0.004 and intercourse with drug addicts (p = 0.005. The only variables associated significantly and independently to HCV seropositivity in patients' contacts were intercourse with drug addicts (OR = 19.28; 95% CI: 2.01 – 184.94, the retirement status from work (OR = 3.76; 95% CI: 1.17 – 11.98, the time of the relationship (OR = 1.06; 95% CI: 1.00 – 1.11 and tattoos (OR = 7.68; 95% CI: 1.00 – 60.20. Conclusion The present study confirms that having intercourse with a drug addict is the most significant risk factor for intrafamilial HCV transmission. The association with retirement status from work could be related to both a long-term relationship with an index case and past exposure to common risk factors.

  17. Is there a link between seropositivity to Helicobacter pylori and hepatitis A virus? A systematic review.

    Since hepatitis A virus (HAV) is acquired primarily through the fecal-oral pathway, several investigators have used HAV seropositivity as a proxy for exposure to this pathway. This paper is a critical review of the evidence relevant to the association between seropositivity to HAV and Helicobacter pylori, and considers the validity of comparisons for testing the hypothesis that H. pylori spreads by the fecal-oral route. A Medline search identified reports of all types published in the English language literature that were linked to the keywords 'Campylobacter pylori', 'hepatitis A', or 'Helicobacter pylori', cross-referenced with 'seroepidemiology', 'seroprevalence', or 'seropositivity'. Studies identified by the search were included in the review if they used specific IgG antibodies to classify the serostatus of subjects for both HAV and H. pylori infection and provided an estimate of the magnitude of the association between HAV and H. pylori or information that permitted calculation of an odds ratio (OR). Out of the 21 studies identified, 15 met the inclusion criteria. The studies showed ORs for an association of HAV and H. pylori that ranged from 0.81 to 8.4. After adjustment for potential confounders, ORs shifted toward the null. They also showed that HAV seroprevalence is lower than H. pylori seroprevalence in early life and then becomes higher in later life. Thus in most populations, the trends cross over at some point. The observed associations between the two infections are generally overestimated by the confounding effects of age and socio-economic status-related factors, and when these factors are controlled, the association becomes weak. Moreover, HAV infection elicits a long-term antibody response, while H. pylori infection does not. Consequently, serostatus comparison does not constitute a convincing test of the fecal-oral transmission hypothesis for H. pylori. Copyright 2009 International Society for Infectious Diseases.

    2017-05-01

    Across South Africa there is a growing body of work that explores gender dynamics in heterosexual relationships between young people aged 15-24 years. This is mainly influenced by the high prevalence of HIV and the incidence of intimate partner violence in this age group. Most studies to date have been based upon non-disabled young people, with limited focus on young disabled people. In an attempt to address this gap, this paper describes findings from a study conducted with 22 Zulu-speaking young people with visual and physical disabilities in KwaZulu-Natal. Throughout the findings, young disabled participants appeared to downplay their disability with respect to intimate relationships and accentuated the interweaving of complementary and contentious discourses of gender and cultural identity. Taking cognisance of the intersectionality of gender and cultural discourses, the paper extend constructs of disabled sexualities beyond an exclusive gaze on disability in the South African context.

    Full Text Available Toxoplasma gondii is a protozoan parasite that causes toxoplasmosis. It is widespread in the environment and infects a variety of warm-blooded animals, causing miscarriages and birth problems. Previous studies in the Philippines have determined the seropositivity of T. gondii in humans. However, the seroprevalence of the parasite among household pets, par ticularly its feline def initive host, remains insufficient . This study aimed to: (1 determine the seroprevalence of T. gondii antibodies among domestic and stray cats in the Philippines; and, (2 to analyze the risk factors associated with seropositivity. Blood samples from 59 domestic and stray cats were collected and tested for T. gondii seropositivity using a commercially available indirect ELISA kit, while pet owners and handlers were given questionnaires about their cats. Thirteen or 22.03% of the cats were seropositive to T. gondii, and risk factor analysis revealed a significant difference between domestic and stray cats with regard to diet (p = 0.026, OR = 8.333, c = 0.299 and domestication (p = 0.039, OR = 5.000, c = 0.276. Cats fed with table food tested 31.43% seropositive compared to the 4.35% of those fed with cat food, whereas 33.33% of the stray cats were seropositive compared to 7.69% for domestic cats. Odds ratio test showed that the risk factors studied were associated with higher likelihood of T. gondii seropositivity. These results implicate diet and environment in the transmission dynamics of T. gondii among cats.

    Leptospirosis is a global zoonosis that in New Zealand affects primarily people occupationally exposed to livestock. The objective of this study was to estimate the seroprevalence of five Leptospira serovars in farmers working on cattle, sheep and deer farms that had the serological status of animals previously assessed and to identify risk factors for farmer seropositivity. A total of 178 farmers from 127 properties participated in the study. Blood samples were tested using the microscopic agglutination test (MAT) for the presence of antibodies to Leptospira. Samples with a MAT titre ≥48 were considered seropositive. Using Bayesian statistical analysis, the median seroprevalence of Leptospira, all serovars combined, was estimated to be 6.6% (95% probability interval (PI) 3.6-10.9%). Risk factors associated with seropositivity were assisting deer or cattle calving, farming deer, having ≥25% of flat terrain and high abundance of wild deer on farm, while high possum abundance on farm was negatively associated with seropositivity. No association was observed between farmer serostatus and previously recorded livestock serology. Leptospira seropositivity was associated with influenza-like illness of farmers (RR = 1.7; 95% PI 1.0-2.5). Assuming a causal relationship, this suggested an annual risk of 1.3% (95% PI 0.0-3.0%) of influenza-like illnesses due to Leptospira infection in the population of farmers. The association between seropositivity and disease can be used to estimate the public health burden of leptospirosis in New Zealand. Identifying and understanding risk factors for Leptospira seropositivity can inform preventive measures, hence contributing to the reduction of leptospirosis incidence in farmers. © 2016 Blackwell Verlag GmbH.

    Contaminated water sources, reservoirs and systems such as evaporative condensers of air-conditioners are known to be the main transmission routes of Legionella spp. which are ubiquitous aquatic bacteria. By virtue of this point the aim of this study was to investigate the rate of Legionella pneumophila seropositivity in a profession considered as risky due to the direct and prolonged exposure to air-conditioning and air-circulating systems. For this purpose, in the period of February-August 2004 a total of 79 male subjects (63 were bus drivers and 16 were driver assistants) who were continously travelling to two different route (South part as hot climate and Middle/North parts as cold climate of Turkey) from Denizli province coach station (a province located in internal Aegian where accepted as crossroads), were included to the study. The mean age and mean working duration of bus drivers were 43.0 +/- 1.1 years and 20.0 +/- 1.1 years, respectively, while these values were 22.5 +/- 0.9 years and 4.0 +/- 0.6 years, respectively, for the drivers' assistants. The serum samples collected from the subjects were screened by a commercial indirect immunofluorescence method (Euroimmun, Germany) using L. pneumophila serogrup 1-14 antigens for the presence of specific antibodies. Additionally, air-conditioners' moisture exhaust samples of the busses in which seropositive subjects travelling with have been examined by culture and 5S rRNA gene targeted polymerase chain reaction (PCR) methods, for the presence of Legionella spp. The overall L. pneumophila seropositivity rate was detected as 15.2% (12/79). This rate was 19% (12/63) for bus drivers while all of the drivers' assistants were found seronegative. The seropositivity rate was found statistically higher in the personnel who were travelling to the hot climates (10/36, 27.8%) than those who travel to cold climates (2/43, 4.6%), (p travel. Our data indicated that long distance bus drivers were chronically exposed to this

    Full Text Available Toxocara canis and T. cati are parasites of dogs and cats, respectively, that infect humans and cause human toxocariasis. Infection may cause asthma-like symptoms but is often asymptomatic and is associated with a marked eosinophilia. Previous epidemiological studies indicate that T. canis infection may be associated with the development of atopy and asthma.To investigate possible associations between Toxocara spp. seropositivity and atopy and childhood wheezing in a population of children living in non-affluent areas of a large Latin American city.The study was conducted in the city of Salvador, Brazil. Data on wheezing symptoms were collected by questionnaire, and atopy was measured by the presence of aeroallergen-specific IgE (sIgE. Skin prick test (SPT, total IgE and peripheral eosinophilia were measured. Toxocara seropositivity was determined by the presence of anti-Toxocara IgG antibodies, and intestinal helminth infections were determined by stool microscopy.Children aged 4 to 11 years were studied, of whom 47% were seropositive for anti-Toxocara IgG; eosinophilia >4% occurred in 74.2% and >10% in 25.4%; 59.6% had elevated levels of total IgE; 36.8% had sIgE≥0.70 kU/L and 30.4% had SPT for at least one aeroallergen; 22.4% had current wheezing symptoms. Anti-Toxocara IgG was positively associated with elevated eosinophils counts, total IgE and the presence of specific IgE to aeroallergens but was inversely associated with skin prick test reactivity.The prevalence of Toxocara seropositivity was high in the studied population of children living in conditions of poverty in urban Brazil. Toxocara infection, although associated with total IgE, sIgE and eosinophilia, may prevent the development of skin hypersensitivity to aeroallergens, possibly through increased polyclonal IgE and the induction of a modified Th2 immune reaction.

    In South Africa, gender inequality dominated by males and heterosexual HIV epidemic are associated with high HIV infection. Underlying epidemiological and social determinants driving HIV acquisition and transmission are critical to understand the extent and complexity of sexual networks as primary mechanisms through which HIV is likely to spread. The aim of the study is to provide an overview of empiric evidence that links the complex interaction of risk of HIV infection in men. We will conduct a systematic scoping review to identify, describe, and map literature on the dynamics of HIV infection in men, and we will determine the quality of the studies reporting on the dynamics of HIV infections in men. Primary research articles, published in peer-reviewed journals, review articles, and gray literature that address the research question, will be included. We will search PubMed, Web of Knowledge, Science Direct, EBSCOhost, Google Scholar, World Health Organization library, and UNAIDS database. Reference lists and existing networks such as government organizations and conferences will also be included to source relevant literature. Two independent reviewers will extract data in parallel from all relevant search engines, using specific inclusion and exclusion criteria. A thematic content analysis will be used to present the narrative account of the reviews, using NVivo version 10. We anticipate finding relevant literature on the dynamics of HIV transmission in South African men. Once summarized, data will be useful to guide future research. PROSPERO CRD42016039489.

    Objectives. We compared the prevalence of condom use during a variety of sexual acts portrayed in adult films produced for heterosexual and homosexual audiences to assess compliance with state Occupational Health and Safety Administration regulations. Methods. We analyzed 50 heterosexual and 50 male homosexual films released between August 1, 2005, and July 31, 2006, randomly selected from the distributor of 85% of the heterosexual adult films released each year in the United States. Results. Penile–vaginal intercourse was protected with condoms in 3% of heterosexual scenes. Penile–anal intercourse, common in both heterosexual (42%) and homosexual (80%) scenes, was much less likely to be protected with condoms in heterosexual than in homosexual scenes (10% vs 78%; P films. Conclusions. Heterosexual films were much less likely than were homosexual films to portray condom use, raising concerns about transmission of HIV and other sexually transmitted diseases, especially among performers in heterosexual adult films. In addition, the adult film industry, especially the heterosexual industry, is not adhering to state occupational safety regulations. PMID:19218178

    Two studies investigated the relation between sexual orientation and gender-related traits. Analyzing data from an Internet survey, Study 1 found that gay men and lesbians differed from same-sex heterosexuals most strongly on gender diagnosticity (GD) measures, which assess male- versus female-typicality of occupational preferences (effect sizes were 1.14 for men and 0.53 for women) and least strongly on instrumentality (I) and expressiveness (E). Study 2 found that GD measures showed large differences between 289 gay and 200 heterosexual men (d = 0.95) and between 296 lesbian and 435 heterosexual women (d = 1.32), whereas I and E showed much smaller differences. In Study 2 homosexual-heterosexual diagnosticity measures, computed from men's and women's occupational preferences, correlated very strongly with GD measures (r = 0.88 for men and 0.89 for women), indicating that occupational preference items that distinguished men from women also tended to distinguish heterosexual from homosexual individuals. LISREL 8 analyses showed that self-ascribed masculinity-femininity did not mediate the strong relation between sexual orientation and GD for men or for women.

    Children who experience parental divorce are less likely to marry heterosexually than those growing up in intact families; however, little is known about other childhood factors affecting marital choices. We studied childhood correlates of first marriages (heterosexual since 1970, homosexual since 1989) in a national cohort of 2 million 18-49 year-old Danes. In multivariate analyses, persons born in the capital area were significantly less likely to marry heterosexually, but more likely to marry homosexually, than their rural-born peers. Heterosexual marriage was significantly linked to having young parents, small age differences between parents, stable parental relationships, large sibships, and late birth order. For men, homosexual marriage was associated with having older mothers, divorced parents, absent fathers, and being the youngest child. For women, maternal death during adolescence and being the only or youngest child or the only girl in the family increased the likelihood of homosexual marriage. Our study provides population-based, prospective evidence that childhood family experiences are important determinants of heterosexual and homosexual marriage decisions in adulthood.

    Current understandings of sexual difficulties originate from a model that is based on the study of heterosexual men and women. Most research has focused on sexual difficulties experienced by heterosexual men incapable of engaging in vaginal penetration. To better understand men's perceptions and experiences of sexual difficulties, seven focus groups and 29 individual interviews were conducted with gay (n = 22), bisexual (n = 5), and heterosexual (n = 25) men. In addition, the extent to which difficulties reported by gay and bisexual men differ from heterosexual men was explored. Data were analyzed using thematic analysis applying an inductive approach. Two intercorrelated conceptualizations were identified: penis function (themes: medicalization, masculine identity, psychological consequences, coping mechanisms) and pain (themes: penile pain, pain during receptive anal sex). For the most part, gay, bisexual, and heterosexual men reported similar sexual difficulties; differences were evident regarding alternative masculinity, penis size competition, and pain during receptive anal sex. The results of this study demonstrate the complexity of men's sexual difficulties and the important role of sociocultural, interpersonal, and psychological factors. Limitations and suggested directions for future research are outlined.

    Concentrations of glutathione, a ubiquitous tripeptide with immune enhancing and antioxidant properties, are decreased in the blood and lung epithelial lining fluid of human immunodeficiency virus (HIV) seropositive individuals. Since the lung is the most common site of infection in those who progress to AIDS it is rational to consider whether it is possible to safely augment glutathione levels in the epithelial lining fluid of HIV seropositive individuals, thus potentially improving local host defence. Purified reduced glutathione was delivered by aerosol to HIV seropositive individuals (n = 14) and the glutathione levels in lung epithelial lining fluid were compared before and at one, two, and three hours after aerosol administration. Before treatment total glutathione concentrations in the epithelial lining fluid were approximately 60% of controls. After three days of twice daily doses each of 600 mg reduced glutathione, total glutathione levels in the epithelial lining fluid increased and remained in the normal range for at least three hours after treatment. Strikingly, even though > 95% of the glutathione in the aerosol was in its reduced form, the percentage of oxidised glutathione in epithelial lining fluid increased from 5% before treatment to about 40% three hours after treatment, probably reflecting the use of glutathione as an antioxidant in vivo. No adverse effects were observed. It is feasible and safe to use aerosolised reduced glutathione to augment the deficient glutathione levels of the lower respiratory tract of HIV seropositive individuals. It is rational to evaluate further the efficacy of this tripeptide in improving host defence in HIV seropositive individuals.

    Syphilis has been known to increase the risk of acquiring or transmitting HIV infection. Epidemiologic studies showed that HIV transmission is 3-5 times higher in people with syphilis.Hence, in this current study, the factors associated with syphilis-seropositive and HIV infection were evaluated.This study used cross-sectional study. This study included inmates at Lubuk Pakam prison in November 2016. After interviewing participants’ demographics and risk behaviors, blood samples were obtained to be tested for HIV and syphilis, using the Rapid Test tool of HIV 3 methods and One STEP Syphilis Anti TP-Test. A total number of 1,114 inmates were included in this study, consisted of 1,081 male (97%) and 33female (3%). Ten inmates were HIV-positive (0.9%), whereas 70 inmates were syphilis-seropositive (6.3%).Based on multivariate-analyses, high-risk sexual behaviors associated with the increased risk of syphilis-seropositive of up to 8.31 times (p=0.002). HIV status also portrayed higher risk of syphilis-seropositive compared to non-HIV participants (3.98 fold, p=0.019). In HIV incidence, found that high-risk sexual behaviors also significantly increased the risk of HIV (7.69 fold, p=0.003). Syphilis-seropositive was also highly associated with HIV risk (5.09 fold, p=0.019).Syphilis and HIV showed a close association with several shared contributing factors.

    Among HIV-positive injection drug users (IDUs), we examined baseline predictors of lending needles and syringes and sharing cookers, cotton, and rinse water in the prior 3 months at follow-up. Participants were enrolled in Intervention for Seropositive Injectors-Research and Evaluation, a secondary prevention intervention for sexually active HIV-positive IDUs in 4 US cities during 2001-2005. The analyses involved 357 participants who reported injecting drugs in the prior 6 months at either the 6- or 12-month follow-up visit. About half (49%) reported at least 1 sharing episode. In adjusted analyses, peer norms supporting safer injection practices and having primary HIV medical care visits in the prior 6 months were associated with reporting no sharing of injection equipment. Higher levels of psychological distress were associated with a greater likelihood of reporting drug paraphernalia sharing. These findings suggest that intervention approaches for reducing HIV-seropositive IDUs' transmission of blood-borne infections should include peer-focused interventions to alter norms of drug paraphernalia sharing and promoting primary HIV care and mental health services.

    Background : Supplementary measles immunization has been implemented since 2010 throughout China, yet few studies have reported its effect in the northwest regions. Methods: A cross-sectional study was conducted among children aged 2 to 4 years old ( n = 755) from February to September 2014 in 25 towns of Qian County, Shaanxi Province. Blood samples were analyzed for measles antibodies using enzyme-linked immunosorbent immunoglobulin G (IgG) assays. Socio-demographic factors were assessed by questionnaire. Data on vaccine dose were collected from town medical records. Univariate and logistic regression analyses were used to determine factors associated with measles antibody seropositivity. Results : Measles antibody seroprevalence was 91.13% (95% CI: 89.52-92.83) in our sample. Compared with children whose mother's highest education was primary school, seroprevalence was higher in children whose maternal education was middle school (adjusted OR: 1.4, 95% CI: 0.7-2.8), high school (adjusted OR: 2.4, 95% CI: 1.3-7.7), and college/university (adjusted OR: 2.9, 95% CI: 1.2-9.3). Vaccine dose was positively associated with seropositivity. Conclusions : Measles seroprevalence is high in China and is associated with the mother's education and vaccine dose.

    The color of normal skin and of oral mucosa is not determined by the number of melanocytes in the epithelium but rather by their melanogenic activity. Pigmented biopolymers or melanins are synthesized in melanosomes. Tyrosinase is the critical enzyme in the biosynthesis of both brown/black eumelanin and yellow/red pheomelanin. The number of the melanosomes within the melanocytes, the type of melanin within the melanosomes, and the efficacy of the transfer of melanosomes from the melanocytes to the neighboring keratinocytes all play an important role in tissue pigmentation. Melanin production is regulated by locally produced factors including proopiomelanocortin and its derivative peptides, particularly alpha-melanocyte-stimulating hormone (α-MSH), melanocortin 1 receptor (MC1R), adrenergic and cholinergic agents, growth factors, cytokines, and nitric oxide. Both eumelanin and pheomelanin can be produced by the same melanocytes, and the proportion of the two melanin types is influenced by the degree of functional activity of the α-MSH/MC1R intracellular pathway. The cause of HIV oral melanosis is not fully understood but may be associated with HIV-induced cytokine dysregulation, with the medications commonly prescribed to HIV-seropositive persons, and with adrenocortical dysfunction, which is not uncommon in HIV-seropositive subjects with AIDS. The purpose of this article is to discuss some aspects of melanocyte biology and HIV-associated oral melanin hyperpigmentation.

    Full Text Available Ebolaviruses (EBOV (family Filoviridae cause viral hemorrhagic fevers in humans and non-human primates when they spill over from their wildlife reservoir hosts with case fatality rates of up to 90%. Fruit bats may act as reservoirs of the Filoviridae. The migratory fruit bat, Eidolon helvum, is common across sub-Saharan Africa and lives in large colonies, often situated in cities. We screened sera from 262 E. helvum using indirect fluorescent tests for antibodies against EBOV subtype Zaire. We detected a seropositive bat from Accra, Ghana, and confirmed this using western blot analysis. The bat was also seropositive for Lagos bat virus, a Lyssavirus, by virus neutralization test. The bat was fitted with a radio transmitter and was last detected in Accra 13 months after release post-sampling, demonstrating long-term survival. Antibodies to filoviruses have not been previously demonstrated in E. helvum. Radio-telemetry data demonstrates long-term survival of an individual bat following exposure to viruses of families that can be highly pathogenic to other mammal species. Because E. helvum typically lives in large urban colonies and is a source of bushmeat in some regions, further studies should determine if this species forms a reservoir for EBOV from which spillover infections into the human population may occur.

  17. Estimating the Number of Heterosexual Persons in the United States to Calculate National Rates of HIV Infection.

    Full Text Available This study estimated the proportions and numbers of heterosexuals in the United States (U.S. to calculate rates of heterosexually acquired human immunodeficiency virus (HIV infection. Quantifying the burden of disease can inform effective prevention planning and resource allocation.Heterosexuals were defined as males and females who ever had sex with an opposite-sex partner and excluded those with other HIV risks: persons who ever injected drugs and males who ever had sex with another man. We conducted meta-analysis using data from 3 national probability surveys that measured lifetime (ever sexual activity and injection drug use among persons aged 15 years and older to estimate the proportion of heterosexuals in the United States population. We then applied the proportion of heterosexual persons to census data to produce population size estimates. National HIV infection rates among heterosexuals were calculated using surveillance data (cases attributable to heterosexual contact in the numerators and the heterosexual population size estimates in the denominators.Adult and adolescent heterosexuals comprised an estimated 86.7% (95% confidence interval: 84.1%-89.3% of the U.S. population. The estimate for males was 84.1% (CI: 81.2%-86.9% and for females was 89.4% (95% CI: 86.9%-91.8%. The HIV diagnosis rate for 2013 was 5.2 per 100,000 heterosexuals and the rate of persons living with diagnosed HIV infection in 2012 was 104 per 100,000 heterosexuals aged 13 years or older. Rates of HIV infection were >20 times as high among black heterosexuals compared to white heterosexuals, indicating considerable disparity. Rates among heterosexual men demonstrated higher disparities than overall population rates for men.The best available data must be used to guide decision-making for HIV prevention. HIV rates among heterosexuals in the U.S. are important additions to cost effectiveness and other data used to make critical decisions about resources for

    Attitudes of Italian heterosexual men and women toward gay men, both HIV positive and negative, are poorly investigated. Italian culture is still extremely conservative and provides limited support to the gay community (e.g., lack of same-sex marriage recognition). Consequently, gay men experience social exclusion and disparities. The present study explores the association between homophobia and closeness with sexual orientation and HIV status. 261 heterosexual Italian men and women were assessed for feelings of closeness and homophobia after reading a vignette where the character was C1: heterosexual and HIV negative; C2: gay and HIV negative; or C3: gay and HIV positive. Experiences of homophobia and closeness varied depending on gender of participant and condition assigned, and higher levels of homophobia were correlated with lower levels of closeness regardless of HIV status. Implications and future directions are discussed.

    Previous content analyses of magazine images have typically examined within genres but failed to include comparisons between publications intended for various populations. The purpose of this study was to examine depictions of muscularity and thinness of male images in several widely distributed magazines that target male audiences from a variety of genres. Twenty-three magazine titles with the highest circulation rates that targeted heterosexual men, gay men, and general audiences were selected for image analyses. We found that magazines that target gay male audiences depicted images of men who were thinner in comparison to magazines targeting heterosexual men. Both gay and heterosexual magazines depicted male images with greater muscularity than magazines intended for general audiences. Differences in male image depictions in magazines may contribute to the promotion of an unattainable body ideal in some subgroups of gay culture. Copyright © 2012 Elsevier Ltd. All rights reserved.

    The detection of anti-aquaporin-4 autoantibody (AQP-4 Ab) is crucial to detect patients who will develop neuromyelitis optica (NMO); however, there are few studies on the AQP-4 Ab serostatus of patients with neuromyelitis optica spectrum ON. We analyzed the clinical and paraclinical features of neuromyelitis optica spectrum ON patients in China according to the patients' AQP4-Ab serostatus. 125 patients with recurrent and bilateral ON with simultaneous attacks were divided into AQP-4 Ab-seropositive and -seronegative groups. Demographic, clinical, serum autoantibody data, connective tissue disorders (CTDs), visual performance were compared. A Visual Acuity (VA) of less than 0.1 during acute ON attacks occurred more frequently in the seropositive group (p = 0.023); however, there was not a significant difference between groups on VA recovery after the first attack. The seropositive group experienced the worst outcome during the last attack (p = 0.017). Other co-existing autoimmunity antibodies (p optica spectrum ON.

    Objective To determine if Chlamydia trachomatis (Ct) seropositivity as detected by the Ct elementary body (EB)-based enzyme linked immunosorbent assay (Ct EB ELISA) predicts pregnancy and pregnancy outcome among infertile women with documented tubal patency. Design Cohort study Setting Outpatient clinics participating in the reproductive medicine network Patients 1250 infertile women with documented tubal patency enrolled in one of two randomized controlled trials: PPCOSII and AMIGOS Intervention Sera were analyzed for anti-Ct IgG1 and IgG3 antibodies using a research Ct EB ELISA. OD405 readings ≥0.35 and ≥0.1 were considered positive for IgG1 and IgG3, respectively. Main Outcome Measures Primary outcomes included pregnancy, live birth, and ectopic pregnancy. Log linear regression was used to determine the relative risk after adjusting for age, race, treatment medication, smoking status, and current alcohol use. Results 243 (19%) women were seropositive for anti-Ct IgG3. They tended to be non-White and smokers. Anti-Ct IgG3 seropositive women were significantly less likely to conceive (RR 0.65, 95% CI 0.52-0.83) or to have a live birth (RR 0.59, 95% 0.43-0.80); these associations were weakened after adjusting for number of HSG-documented patent tubes (RR 0.73, 95% CI 0.56-0.97) and (0.73, 95% CI: 0.50-1.04), respectively. Anti-Ct IgG3 seropositive women who conceived had 2.7 (95% CI: 1.40-5.34) times the risk of ectopic pregnancy. Conclusions Even in the presence of tubal patency, anti-Ct IgG3 seropositivity is associated with lower likelihood of pregnancy. Anti-Ct IgG3 seropositive women have up to 3 times the risk of ectopic pregnancy. PMID:26413816

    We evaluated the effectiveness of Hombres Sanos [Healthy Men] a social marketing campaign to increase condom use and HIV testing among heterosexually identified Latino men, especially among heterosexually identified Latino men who have sex with men and women (MSMW). Hombres Sanos was implemented in northern San Diego County, California, from June 2006 through December 2006. Every other month we conducted cross-sectional surveys with independent samples of heterosexually identified Latino men before (n = 626), during (n = 752), and after (n = 385) the campaign. Respondents were randomly selected from 12 targeted community venues to complete an anonymous, self-administered survey on sexual practices and testing for HIV and other sexually transmitted infections. About 5.6% of respondents (n = 98) were heterosexually identified Latino MSMW. The intervention was associated with reduced rates of recent unprotected sex with both females and males among heterosexually identified Latino MSMW. The campaign was also associated with increases in perception of HIV risk, knowledge of testing locations, and condom carrying among heterosexual Latinos. Social marketing represents a promising approach for abating HIV transmission among heterosexually identified Latinos, particularly for heterosexually identified Latino MSMW. Given the scarcity of evidence-based HIV prevention interventions for these populations, this prevention strategy warrants further investigation.

    1992-09-01

    In an attempt to develop a short neuropsychological test battery five different tests of reaction time were assessed according to their ability to discriminate between HIV seropositive men and healthy controls. In all tests a patient group with clinical symptoms was slower than the control group. In the complex reaction time test, which has a large cognitive aspect, even a clinically "asymptomatic" group was slower than the control group. The movement test, a new test with a large motor component, identified most slow responders, defining approximately half of the patients with clinical symptoms and one third of the "asymptomatic" patients as such. A test battery consisting of three tests is suggested for serial assessment and screening.

    Full Text Available Abstract INTRODUCTION: Emerging diseases are of great interest, especially those associated with high mortality rates such as hantaviruses. We aimed to conduct a seroepidemiological survey to determine the levels of hantavirus infection. METHODS: In-house enzyme-linked immunosorbent assay (ELISA was used to detect specific antibodies. RESULTS: Of the 429 samples collected, seropositivity of 3.9% to anti-hantavirus immunoglobulin G (IgG was observed (CI 95%: 2.3-5.7. Moreover, in three cases, immunoglobulin M (IgM was detected, of which two were diagnosed as hantavirus cardiopulmonary syndrome (HCPS. CONCLUSIONS: Our data indicate the considerable occurrence of previous hantavirus infections, highlighting occurrences from sub-clinical cases to HCPS.

    Full Text Available Background: HIV infection is an unfortunate consequence of a defined set of behaviors. Individuals with continued high-risk behavior either due to personality factors or due to maladaptive coping skills have higher viral loads and morbidity. Research has shown significant interactions between less effective coping styles and personality factors. Aim: This study aimed to evaluate personality traits, coping skills, and their association in male HIV-seropositive cases. Materials and Methods: This was a cross-sectional study, conducted on 86 patients. Informed consent and sociodemographic details, by a structured questionnaire, were obtained. Scales pertaining to personality factors and coping were applied. Statistical analysis was done by SPSS 16. Results: Neuroticism, extraversion, and conscientiousness traits were in the average range. Scores on openness and agreeableness were below average. The results pertaining to coping showed an overall mean score of 50.78, with the highest on physical domain and then on the philosophical domain, the lowest was in social domain. The research sample perceived their coping resources as average. Neuroticism was negatively related to all the coping styles. Extraversion showed relation with physical, emotional, social, and philosophical scales. Openness was related to philosophical and emotional scales. Agreeableness correlated with all domains of coping except the social. Conscientiousness correlated significantly with all the domains of coping. Conclusion: The various personality traits associated with male HIV-seropositive patients were identified and various coping resources used by these were also delineated. Further, the association among them was identified which can help in primary prevention and mental health professionals to have a targeted approach for counseling.

    Full Text Available The aim of this study was to investigate the IgM antibody positivities of atypical pneumonia agents in patients with community-acquired pneumonia (CAP, and to compare the results with controls. The serum samples which were collected from 87 adult patients and 21 healthy controls have been investigated by a commercial ELISA (Pneumobact ELISA IgM, Vircell, Spain in which four different atypical pneumonia agents were fixed onto a slide. In the patients group, IgM positivity rates for the agents were as follows, respectively; 2.3% for Legionella pneumophila, 56.3% Chlamydia pneumoniae, 33.3% for Mycoplasma pneumoniae, 9.2% for Coxiella burnetii. The rates of IgM positivities in the control group varied 7% for all of the agents except M. Pneumoniae and C. Pneumoniae and 2 of these controls were positive for L. Pneumophila IgM, one was positive for C. Burnetii IgM. According to the statistical evaluation, there were significant differences for IgM seropositivities to Mycoplasma pneumoniae and Chlamydia Pneumoniae,between the patient and the control groups (p0.05. We showed that the seropositivity rate of atypical agents in patients with CAP was significantly higher when compared to healthy control group. This result suggests us, atypical agents might be responsible in CAP patients in a great amount. Furthermore, our study also suggests that clinical and radiological findings are not useful for discriminating atypical from typical pneumonia. [TAF Prev Med Bull 2007; 6(4.000: 279-284

    The combination of an immature immune system and suppressed cellular immunity in children with HIV infections provides optimal conditions for rapid disease progression. As a result, pediatric AIDS has become a major epidemiological challenge. Oral fungal colonization remains one of the most common opportunistic infections observed in both adult and pediatric HIV infected patients. Although Candida albicans is the most frequently isolated opportunistic fungal species, a recently characterized Candida species, C. dubliniensis, has gained considerable attention due to its almost exclusive association with HIV-seropositive individuals. The purpose of this study was to prospectively screen for the presence of C. dubliniensis among pediatric HIV+ patients. Oral samples taken from twenty-seven children were cultured for the presence of yeast. All positive yeast isolates obtained were screened for the presence of C. dubliniensis by use of tests for germ tube and chlamydospore production, detection of inability to grow at 45 degrees C, by colony color on CHROMagar Candida medium, coaggregation with Fusobacterium nucleatum ATCC 49256 and by the results of sugar assimilation testing with the API 20C AUX yeast identification system. Among the 27 patients tested, 3 patients were found to harbor C. dubliniensis, one of which also grew C. glabrata; 12 patients were colonized with C. albicans, while the remaining 12 patients were negative for yeast. Identification of the three C. dubliniensis isolates was genetically confirmed by electrophoretic karyotyping. All three C. dubliniensis isolates were found to be susceptible to fluconazole (MIC pediatric HIV seropositive population and support the need for further investigation into the prevalence and pathogenesis of C. dubliniensis.

    Family planning has become increasingly important as a fundamental component of sexual health and as such is offered via public health systems worldwide. Identification of barriers to use of family planning methods among heterosexual couples living in Mexico is indicated to facilitate access to family planning methods. Barriers to family planning methods were assessed among Mexican heterosexual, sexually active males and females of reproductive age, using a modified Spanish version of the Barriers to the Use of Family Planning Methods scale (Cronbach's alpha = .89, subscales ranging from .53 to .87). Participants were recruited via convenience sampling in ambulatory care clinics within a metropolitan area in Central Mexico. Participants included 52 heterosexual couples aged 18-35 years (N = 104). Sociodemographic comparisons by gender identified older age and higher education, income, and numbers of sexual partners among men than women. More men (50%) than women (25%) were currently using family planning methods; however, 80% overall indicated intentions for its use. Overall, male condoms were used and intended for use most often by men than women. Significant gender-specific differences were found, with men (71.15%) reporting no family planning barriers, whereas women (55.66%) reported barriers including low socioeconomic status, medical concerns, and stigma. The modified Spanish translation demonstrated usefulness for measuring barriers to family planning methods use in Mexico among heterosexual males and females of reproductive age. Barriers identified by Mexican women in this study may be addressed to reduce potential barriers to family planning among Mexican populations.

    Full Text Available Objective: the purpose of this study was to study relationship between interaction parent-child with addictability rate and heterosexual orientation in students. Method: The statistical population consisted of all students of Guilan University in 2012-2013 academic year, which among them a sample of 200 students were selected by random cluster sampling method and they completed preparation to addiction scale relationship between parent–child scale and attitude and heterosexual orientation before marriage. Findings: Correlation analysis indicated a significant negative correlation between addictability in female students and male students with relationship with father, and positive affect, interlace and communication subscales. The relationship between female students’ addictability with relationship with mother and positive affect, hurt and confusion and communication subscales was observed significant negative correlation, also there is a significant negative relationship between male students’ addictability with the relationship with mother. There is significant negative relationship between heterosexual orientations in male students with relation with father, positive affects and interlace. Results of regression analysis showed that relationship with father and relationship with mother can anticipate addict ability in female and male students. Conclusion: If parents cannot establish an appropriate and constructive interaction with their child cause child face with affection and emotional deprivation and this poor emotional and affection deprivation may cause he or she bring to the addict ability and heterosexual orientation.

    The current longitudinal study examined patterns and predictors of parent-reported gender-typed play behavior in adopted boys and girls in lesbian, gay, and heterosexual two-parent families, across early childhood (Mage = 2.82 to 6.06 years). Specifically, using a sample of 181 couples (56 lesbian couples, 48 gay male couples, and 77 heterosexual couples), we examined parent reports of children’s gender-typed play behavior on the Pre-School Activities Inventory (PSAI; Golombok & Rust, 1993) at three time points (mean age = 2.82 years at T1, 3.93 years at T2, and 6.06 years at T3). Family structure variables (i.e., parents’ gender and sexual orientation; children’s gender and sibling status) were included as predictors. At T1, according to parent reports, children in lesbian-parent families had less gender-differentiated behavior (boys were less masculine, girls were less feminine) than children in heterosexual- and gay-parent families, whereas the degree of gender differentiation did not differ between heterosexual- versus gay-parent families. Findings from a Common Fate Growth Model (Ledermann & Macho, 2014) revealed that, regardless of family type, the parent-reported gender-typed behavior of boys, but not girls, significantly changed over time (i.e., boys’ behavior became more masculine). Our findings have implications for researchers who study gender development in children and adolescents, particularly those who are being raised by two mothers or two fathers. PMID:27416364

    2013-01-01

    Engagement in activism is related to several aspects of social development in adolescence and emerging adulthood. Therefore, it is important to examine the correlates of different forms of activism, such as feminist collective action, among all youth. However, previous research has not investigated young sexual-minority women's engagement with feminist collective action. This study examined predictors of college-aged heterosexual and sexual-minority women's commitment to and participation in feminist activism. Sexual orientation, number of years in college, social support, experiences with discrimination, and gender identity were tested as predictors of commitment to and participation in feminist activism with a sample of 280 college-aged women (173 heterosexuals and 107 sexual minorities). Similar predictors were related to both commitment to and participation in feminist activism. However, for sexual-minority women, but not heterosexual women, the number of years in college was correlated with participation in feminist activism. Young sexual-minority women reported more participation in feminist activism than did heterosexual women, even after controlling for social support, discrimination, and gender identity.

    Full Text Available Iatrogenous transmission of Trypanosoma cruziby blood transfusion was suggested as a potential risk by Pellegrino (1949. Seropositive blood donors in Mexico were first reported in 1978, however, limited information is available due to small sampling, the use of heterogeneous serologic assays, and geographically limited studies. A wide survey carried out in 18 out of the 32 states of Mexico, showed a national mean of 1.6% seropositive among 64,969 donors, ranging from 0.2 to 2.8%. In the present study, we have screened 43,048 voluntary blood donors in a period of five years at the Instituto Nacional de Cardiología I. Chávez, a concentration hospital located in Mexico city which serves mainly the metropolitan area and accepts from all over the country. Standardized ELISA and IIF were used to identify seropositive individuals in addition to hemoculture, PCR and standard 12 lead ECG tests that were applied to a group of seropositive patients (29/161. The result showed a seropositivity of 0.37% (161/43,048. From the group of seropositive individuals 40% (12/29 were potential carriers of T. cruzi at the donation time and 5/29 had subclinical ECG abnormalities. Parasitological tests performed in 70 erythrocyte and platelet fractions from seropositive units (70/161 showed negative results. Our findings strongly support T. cruzi screening in the transfusion medicine practice and identify subclinical heart disease among seropositive blood donors.

    John R Stack

    Full Text Available Anti-citrullinated protein antibodies (ACPA have been shown to cause platelet activation in vitro, through the low-affinity immunoglobulin G (IgG receptor (FcγRIIa on platelets. Platelet activation via engagement of FcγRIIa results in proteolytic cleavage and shedding of platelet specific glycoprotein VI (GPVI which can be detected in the plasma as soluble GPVI (sGPVI. We hypothesized that plasma levels of sGPVI would be increased among patients with seropositive RA as a consequence of antibody-induced platelet activation and GPVI shedding.Samples from 84 patients with RA (65 seropositive and 19 seronegative and 67 healthy controls were collected prospectively and analysed for sGPVI using a standardised ELISA.Patients with seropositive RA had significantly higher levels of sGPVI compared to seronegative RA and controls. Median (IQR sGPVI levels were 4.2 ng/ml (3.2, 8.0 in seropositve RA, 2.2 ng/ml (1.5, 3.5 in seronegative RA and 2.2 ng/ml (1.6, 3.4 in controls (p<0.0001. sGPVI levels correlated with ACPA titres (r = 0.32, p = 0.0026 and with RF titres (r = 0.48, p<0.0001.Plasma sGPVI, a specific marker of platelet activation is increased among patients with seropositive RA.

    Heterosexually active Black men are alleged to endorse masculine norms that increase their and their female partners' vulnerability to HIV. These norms include Black men's inability or reluctance to productively engage their own health-related personal and interpersonal vulnerabilities. We draw on data from the iSpeak research study in Ontario, Canada, to assess whether and how heterosexual Black men cope with personal and inter-personal vulnerability, namely that heterosexual Black men: avoid emotionally supportive relationships with other men (and women), which diminishes their capacity to productively acknowledge and resolve their health-related challenges; are reticent to productively acknowledge and address HIV and health on a personal level; and are pathologically secretive about their health, which compounds their vulnerability and precipitates poor health outcomes. iSpeak was implemented in 2011 to 2013, and included two focus groups with HIV-positive and HIV-negative self-identified heterosexual men (N = 14) in Toronto and London, a focus group with community-based health promotion practitioners who provide HIV-related services to Black communities in Ontario (N = 6), and one-on-one interviews with four researchers distinguished for their scholarship with/among Black communities in Toronto. Participants in the men's focus group were recruited discretely through word-of-mouth. Focus groups were audiotaped and transcribed verbatim. Team members independently read the transcripts, and then met to identify, discuss and agree on the emerging themes. We demonstrate that iSpeak participants (a) engage their personal and interpersonal vulnerabilities creatively and strategically, (b) complicate and challenge familiar interpretations of Black men's allegedly transgressive masculinity through their emotional and practical investment in their health, and (c) demonstrate a form of resourceful masculinity that ambiguously aligns with patriarchy. We conclude

    To examine the development of muscularity and weight concerns among heterosexual and sexual minority males in adolescence. Participants were 5,868 males from the Growing Up Today Study, a U.S. prospective cohort spanning ages 9-25 years. Generalized estimating equations were used to test sexual orientation differences in the development of muscularity concerns, weight gain attempts, and weight and shape concern. Desire for bigger muscles increased slightly each year across adolescence (β = .10, 95% C.I. = .09, .11) regardless of sexual orientation, but gay and bisexual participants reported greater desire for toned muscles than completely and mostly heterosexual males (β = .39, 95% C.I. = .21, .57). Desire for toned muscles did not change with age. Attempts to gain weight increased threefold across adolescence, with up to 30% reporting weight gain attempts by age 16. Although underweight males (the smallest weight status class) were most likely to attempt to gain weight, most of the observed weight gain attempts were by healthy (69%) and overweight/obese (27%) males, suggesting that most attempts were medically unnecessary and could lead to overweight. Sexual minority participants were 20% less likely to report weight gain attempts than completely heterosexual participants. Weight and shape concern increased with age, with gay and bisexual participants experiencing a significantly greater increase than heterosexual males. Sexual orientation modifies the development and expression of male weight and muscularity concerns. The findings have implications for early interventions for the prevention of obesity and eating disorder risk in heterosexual and sexual minority males.

    Adolescent school absenteeism is associated with negative outcomes such as conduct disorders, substance abuse, and dropping out of school. Mental health factors, such as depression and anxiety, have been found to be associated with increased absenteeism from school. Sexual minority youth (youth who are attracted to the same sex or endorse a gay, lesbian, or bisexual identity) are a group at risk for increased absenteeism due to fear, avoidance, and higher rates of depression and anxiety than their heterosexual peers. The present study used longitudinal data to compare sexual minority youth and heterosexual youth on excused and unexcused absences from school and to evaluate differences in the relations between depression and anxiety symptoms and school absences among sexual minority youth and heterosexual youth. A total of 108 14- to 19-years-old adolescents (71% female and 26% sexual minority) completed self-report measures of excused and unexcused absences and depression and anxiety symptoms. Compared to heterosexual youth, sexual minority youth reported more excused and unexcused absences and more depression and anxiety symptoms. Sexual minority status significantly moderated the effects of depression and anxiety symptoms on unexcused absences such that depression and anxiety symptoms were stronger predictors of unexcused absences for sexual minority youth than for heterosexual youth. The results demonstrate that sexual minority status and mental health are important factors to consider when assessing school absenteeism and when developing interventions to prevent or reduce school absenteeism among adolescents.

  10. Heterosexual assumptions in verbal and non-verbal communication in nursing.

    2006-11-01

    This paper reports a study of what lesbian women and gay men had to say, as patients and as partners, about their experiences of nursing in hospital care, and what they regarded as important to communicate about homosexuality and nursing. The social life of heterosexual cultures is based on the assumption that all people are heterosexual, thereby making homosexuality socially invisible. Nurses may assume that all patients and significant others are heterosexual, and these heteronormative assumptions may lead to poor communication that affects nursing quality by leading nurses to ask the wrong questions and make incorrect judgements. A qualitative interview study was carried out in the spring of 2004. Seventeen women and 10 men ranging in age from 23 to 65 years from different parts of Sweden participated. They described 46 experiences as patients and 31 as partners. Heteronormativity was communicated in waiting rooms, in patient documents and when registering for admission, and nursing staff sometimes showed perplexity when an informant deviated from this heteronormative assumption. Informants had often met nursing staff who showed fear of behaving incorrectly, which could lead to a sense of insecurity, thereby impeding further communication. As partners of gay patients, informants felt that they had to deal with heterosexual assumptions more than they did when they were patients, and the consequences were feelings of not being accepted as a 'true' relative, of exclusion and neglect. Almost all participants offered recommendations about how nursing staff could facilitate communication. Heterosexual norms communicated unconsciously by nursing staff contribute to ambivalent attitudes and feelings of insecurity that prevent communication and easily lead to misconceptions. Educational and management interventions, as well as increased communication, could make gay people more visible and thereby encourage openness and awareness by hospital staff of the norms that they

    Homosexuality is a recognized risk factor for depression in high-income countries; however, there is little research investigating the relationship between depression and sexual orientation in developing countries, especially in Africa. In this first study to investigate psychopathology in sexual minority men in Nigeria, the prevalence rates of depression in Nigerian gay and heterosexual individuals were compared as well as the explanatory power of risk and resilience factors in both groups. Eighty-one gay and 81 heterosexual male university students were, respectively, recruited from the Obafemi Awolowo University. Both groups were assessed for depression and other clinical factors, including alcohol and other substance use, suicidal ideation, and resilience. Gay students were further assessed for sexuality-related variables, including minority stress factors such as internalized homophobia and perceived stigma. The prevalence rates of depression among gay and heterosexual students were, respectively, 16 and 4.9% (OR 3.7; 95% CI 1.15-11.82), and this increased likelihood for depression was significantly attenuated by resilience. Clinical factors correlated significantly with depression in both groups, explaining 31% of the variance in depression in gay and heterosexual students, respectively. Sexuality-related variables including internalized homophobia and perceived stigma were further associated with depression in gay students-accounting for a further 14% of the variance of depression in gay students. The findings highlight the importance of minority stress factors in understanding depression among non-heterosexual individuals in a developing country, and the need for further research to investigate the mechanisms of these relationships in such settings.

  12. Not a surgical vaccine: there is no case for boosting infant male circumcision to combat heterosexual transmission of HIV in Australia.

    2011-10-01

    To conduct a critical review of recent proposals that widespread circumcision of male infants be introduced in Australia as a means of combating heterosexually transmitted HIV infection. These arguments are evaluated in terms of their logic, coherence and fidelity to the principles of evidence-based medicine; the extent to which they take account of the evidence for circumcision having a protective effect against HIV and the practicality of circumcision as an HIV control strategy; the extent of its applicability to the specifics of Australia's HIV epidemic; the benefits, harms and risks of circumcision; and the associated human rights, bioethical and legal issues. Our conclusion is that such proposals ignore doubts about the robustness of the evidence from the African random-controlled trials as to the protective effect of circumcision and the practical value of circumcision as a means of HIV control; misrepresent the nature of Australia's HIV epidemic and exaggerate the relevance of the African random-controlled trials findings to it; underestimate the risks and harm of circumcision; and ignore questions of medical ethics and human rights. The notion of circumcision as a 'surgical vaccine' is criticised as polemical and unscientific. Circumcision of infants or other minors has no place among HIV control measures in the Australian and New Zealand context; proposals such as these should be rejected. © 2011 The Authors.

    Few studies demonstrated neural circuits related to disgust were influenced by internal sexual orientation in male. Here we used fMRI to study the neural responses to disgust in homosexual and heterosexual men to investigate that issue. Thirty-two healthy male volunteers (sixteen homosexual and sixteen heterosexual) were scanned while viewing alternating blocks of three types of erotic film: heterosexual couples (F-M), male homosexual couples (M-M), and female homosexual couples (F-F) engaged in sexual activity. All the participants rated their level of disgust and sexual arousal as well. The F-F and M-M stimuli induced disgust in homosexual and heterosexual men, respectively. The common activations related to disgusting stimuli included: bilateral frontal gyrus and occipital gyrus, right middle temporal gyrus, left superior temporal gyrus, right cerebellum, and right thalamus. Homosexual men had greater neural responses in the left medial frontal gyrus than did heterosexual men to the sexual disgusting stimuli; in contrast, heterosexual men showed significantly greater activation than homosexual men in the left cuneus. ROI analysis showed that negative correlation were found between the magnitude of MRI signals in the left medial frontal gyrus and scores of disgust in homosexual subjects (p < 0.05). This study indicated that there were regions in common as well as regions specific for each type of erotic stimuli during disgust of homosexual and heterosexual men.

    Few studies demonstrated neural circuits related to disgust were influenced by internal sexual orientation in male. Here we used fMRI to study the neural responses to disgust in homosexual and heterosexual men to investigate that issue. Thirty-two healthy male volunteers (sixteen homosexual and sixteen heterosexual) were scanned while viewing alternating blocks of three types of erotic film: heterosexual couples (F-M), male homosexual couples (M-M), and female homosexual couples (F-F) engaged in sexual activity. All the participants rated their level of disgust and sexual arousal as well. The F-F and M-M stimuli induced disgust in homosexual and heterosexual men, respectively. The common activations related to disgusting stimuli included: bilateral frontal gyrus and occipital gyrus, right middle temporal gyrus, left superior temporal gyrus, right cerebellum, and right thalamus. Homosexual men had greater neural responses in the left medial frontal gyrus than did heterosexual men to the sexual disgusting stimuli; in contrast, heterosexual men showed significantly greater activation than homosexual men in the left cuneus.

    The purpose of the present study was twofold: (1) to investigate the effects of sexual orientation (heterosexuals and gay men/lesbians) and gender difference on responses to romantic relationship problems (Exit, Voice, Loyalty, and Neglect [EVLN] responses) and of perceived partner's EVLN responses in Turkey, and (2) to examine whether internalized homophobia was associated with EVLN responses and perceived partner's EVLN responses for gay men and lesbians. Responses to Dissatisfaction Scale-Accommodation Instrument, Internalized Homophobia, and Demographics Information were administered to 187 participants (44 lesbians, 44 gay men, 53 heterosexual women, 46 heterosexual men).The MANCOVA results showed that men reported higher loyalty than women, whereas women presented more exit responses than men. Further, the interactions between gender and sexual orientation on the participants' EVLN responses and on the perceived partner's EVLN responses were significant. With respect to heterosexual women, heterosexual men displayed more loyalty responses. Lesbians had higher scores on loyalty than did heterosexual women. Lesbians also had higher scores on perceived partner's exit response than did heterosexual women and gay men. On the contrary, heterosexual women reported more perceived partner's voice response than lesbians. In addition, lesbians reported higher perceived partner's neglect responses than heterosexual women. Compared to heterosexual women, heterosexual men reported higher perceived partner's exit response. Finally, internalized homophobia was associated with destructive responses for both lesbians and gay men.

    Background: Asymptomatic central nervous system involvement may occur in the early stages of the HIV infection. The aim of the study was to evaluate early brain metabolic changes by means of proton MR spectroscopy (H1MRS) in the HIV-1 seropositive patients without neurological deficits or significant abnormalities in the plain MR study. Material/Methods: The H1MRS examinations were performed with the use of a MR GE Signa 1,5 T system. There were 39 subjects examined, aged 21 to 57 years (mean age 35 years) were examined, including 25 patients infected with HIV-1 and 14 healthy volunteers who constituted a control group. The examinations were performed using the Single Voxel Spectroscopy technique with the PRESS sequence, with following parameters: TR=1500 ms, TE=35 ms, number of acquisitions =128, time of acquisition =3 min. 43 sec. Voxels of 8 cm 3 (20 x 20 x 20 mm) in size were located in the following 5 regions: posterior cingulate gyrus, grey matter of the frontal area, left basal ganglia, white matter of the left parietal area and white matter of the frontal area. The NAA/Cr, Cho/Cr, mI/Cr ratios in the defined regions of interest were statistically analyzed. Results: There was a statistically significant decrease (p < 0.05) in the NAA/Cr ratios in the posterior cingulate area and white matter of the left parietal area in HIV-1 seropositive patients, as compared to the control group. Other metabolite ratios in all the above mentioned locations showed no statistically significant differences, as was also the case for NAA/Cr ratios in grey matter of the frontal area, left basal ganglia and white matter of the frontal area. Conclusions: The reduction of NAA/Cr values revealed in H1MRS studies suggests loss of neurons/neuronal activity in the posterior cingulate area and white matter of the left parietal area, in patients with HIV-1 at the stage before clinical manifestations of retroviral infection and structural changes in the plain MR study. This may reflect a

    A recent randomized trial demonstrated that 1 year of antiviral prophylaxis for cytomegalovirus (CMV) after lung transplantation is superior to 3 months of treatment for prevention of CMV disease. However, it is uncertain if a shorter duration of prophylaxis might result in a similar rate of CMV disease among select lung transplant (LT) recipients who are at lower risk for CMV disease, based on baseline donor (D) and recipient (R) CMV serologies. We retrospectively assessed incidence, cumulative probability, and predictors of CMV disease and viremia in LT recipients transplanted between July 2004 and December 2009 at our center, where antiviral CMV prophylaxis for 6-12 months is standard. Of 129 LT recipients, 94 were at risk for CMV infection based on donor CMV seropositivity (D+) or recipient seropositivity (R+); 14 developed CMV disease (14.9%): 11 with CMV syndrome, 2 with pneumonitis, and 1 with gastrointestinal disease by the end of follow-up (October 2010); 17 developed asymptomatic CMV viremia (18.1%). The cumulative probability of CMV disease was 17.4% 18 months after transplantation. CMV D+/R- recipients who routinely received 1 year of prophylaxis were more likely to develop CMV disease compared with D+/R+ or D-/R+ recipients, who routinely received 6 months of prophylaxis (12/45 vs. 2/25 vs. 0/24, P = 0.005). Recipients who stopped CMV prophylaxis before 12 months (in D+/R- recipients) and 6 months (in R+ recipients) tended to develop CMV disease more than those who did not (9/39 vs. 3/41, P = 0.06). On a 6-month CMV prophylaxis protocol, few R+ recipients developed CMV disease in this cohort. In contrast, despite a 12-month prophylaxis protocol, D+/R- LT recipients remained at highest risk for CMV disease. © 2012 John Wiley & Sons A/S.

    Full Text Available Background: Current laboratory criteria for antiphospholipid syndrome (APS classification recommend testing positive for antiphospholipid (aPL antibodies. However, there appears to be a subset of patients with classical APS manifestations who test negative. Aim of the work: To analyze the potential clinical usefulness of testing for anti-annexin A5 antibodies in patients with APS and to study the effectiveness of testing for non-criteria aPLs in an attempt to increase the diagnostic yield, particularly in seronegative APS. Patients and methods: 60 APS patients were divided into two groups; 30 seropositive (SP-APS (group I and 30 age and sex matched seronegative (sN-APS testing negative for aPL antibodies. Serum assay for detection of isotypes of anti-annexin A5 antibodies (IgG and IgM were conducted. Results: The mean age of the patients was 32.9 ± 5.8 years, female:male 57:3 and disease duration in SP-APS versus sN-APS (10.17 ± 4.9 years versus 9.6 ± 5.5 years respectively. Secondary APS was present in 16(53.3% patients in group I compared to 3(10% in group II (p < 0.0001. The mean anti-AnxA5 IgG level was 10.7 ± 5.6 U/ml and IgM was 11.2 ± 7.1 U/ml and were comparable between the 2 groups. The obstetric and thrombotic morbidity had no significant differences between SP and sN-APS. The IgG and IgM levels significantly correlated with the pregnancy morbidity, venous and arterial thrombosis events and showed reasonable sensitivities in their prediction (IgG:71.2%,72.8% and 75.8%; IgM: 68%,67.8% and 71.4% respectively and specificities (IgG:75.9%,77.8% and 81.5%; IgM: 70.9%,73.1% and 73.7% respectively. Conclusion: anti-annexinA5 antibodies are promising for detecting obstetric and thrombotic morbidity in both SP- and sN-APS patients.

    To determine if Chlamydia trachomatis (C. trachomatis) seropositivity, as detected by the C. trachomatis elementary body (EB)-based enzyme-linked immunosorbent assay [EB ELISA] predicts pregnancy and pregnancy outcome among infertile women with documented tubal patency. Cohort study. Outpatient clinics. In all, 1,250 infertile women with documented tubal patency enrolled in 1 of 2 randomized controlled trials: Pregnancy in Polycystic Ovary Syndrome II; and the Assessment of Multiple Intrauterine Gestations From Ovarian Stimulation. Sera were analyzed for anti-C. trachomatis immunoglobulin G (IgG)1 and IgG3 antibodies, using a research C. trachomatis EB ELISA. The optical density (OD)405 readings of ≥ 0.35 and ≥ 0.1 were considered positive for IgG1 and IgG3, respectively. Primary outcomes included pregnancy, live birth, and ectopic pregnancy. Log-linear regression was used to determine the relative risk after adjusting for age, race, treatment medication, smoking status, and current alcohol use. A total of 243 (19%) women were seropositive for anti-C. trachomatis IgG3. They tended to be nonwhite and smokers. Anti-C. trachomatis IgG3 seropositive women were significantly less likely to conceive (risk ratio [RR] 0.65, 95% confidence interval [CI] 0.52-0.83) or to have a live birth (RR 0.59, 95% CI 0.43-0.80); these associations were weakened after adjusting for number of hysterosalpingography-documented patent tubes (RR 0.73, 95% CI 0.56-0.97) and (RR 0.73, 95% CI 0.50-1.04), respectively. Anti-C. trachomatis IgG3 seropositive women who conceived had a ×2.7 risk (95% CI 1.40-5.34) of ectopic pregnancy. Even in the presence of tubal patency, anti-C. trachomatis IgG3 seropositivity is associated with a lower likelihood of pregnancy. Anti-C. trachomatis IgG3 seropositive women have as high as 3 times the risk of ectopic pregnancy. PPCOSII: NCT00719186 and AMIGOS: NCT01044862.

    Neospora caninum is an important cause of abortion in dairy cattle. The general health of affected cows has not been investigated before. Therefore, the main objective of this study was to identify possible relationships between certain metabolic diseases and selected serum biochemical parameters in seropositive dairy cows against N. caninum antibodies in different stages of lactation. The study was carried out using 72 N. caninum seropositive cows and 61 seronegative dairy cows (control). Serum from all cows was tested to determine their N. caninum status (seropositive vs seronegative) using commercially available indirect enzyme-linked immunosorbent assay test kit (iELISA). In addition, serum biochemical parameters including beta-hydroxybutyrate (BHB), glucose, creatinine, blood urea nitrogen, total protein, albumin, alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine transaminase (ALT), lactate dehydrogenase (LDH) and gamma-glutamyltranspeptidase (GGT) were determined using routine laboratory methods. The stage of lactation was obtained at the time of sampling from farm records. Student independent t-test showed that there was a significant difference in the serum concentrations of BHB, AST, ALT, and LDH between seropositive and seronegative cows. There was no significant association between seropositivity and the stage of lactation. However, multivariable logistic regression analysis showed that there was a strong association between seropositivity and BHB concentrations. Results of this study indicate a possible relationship between N. caninum seropositivity and certain metabolic diseases such as ketosis and fatty liver syndrome in dairy cows.

    Viral hepatitis is a major public health problem. Infection with Hepatitis C virus (HCV) leads to chronicity and there are about 170 million people infected with HCV. Up to 70% of chronically infected individuals develop active liver disease. The Objective of the study was to find out the frequency of Anti-HCV seropositivity and risk factors of Hepatitis C Virus (HCV) transmission in people of Larkana city. The study was conducted at Larkana from April 2006 to April 2007. Camps were established in the main general practitioners' clinics. A questionnaire about knowledge of HCV and risk factors of its transmission was administered to subjects. Descriptive statistics were done by SPSS-10. Total 450 cases were enrolled into this study. They were divided into 3 age groups. Eighty-nine (19.8%) cases were in age group 40 years. There were 353 (78.4%) male and 97 (21.6%) female subjects, out of these 450 cases 30 (6.6%) were positive for Anti-HCV. A number of risk factors of HCV transmission were present in these cases. History of therapeutic injections was present in 72 cases and 35 cases used public barber services. History of therapeutic injections and use of barber services for shave were the most frequent risk factors in our study. (author)

    Obesity potentially arising from viral infection is known as 'infectobesity'. The latest reports suggest that adenovirus-36 (Adv36) is related to obesity in adults and children. Our aim was not only to determine the Adv36 seropositivity in both obese and non-obese children and adults, but also to investigate correlations between antibody positivity and serum lipid profiles. Both Adv36 positivity and tumour-necrosis-factor-alpha, leptin and interleukin-6 levels were detected in blood samples collected from 146 children and 130 adults by ELISA. Fasting plasma triglycerides, total cholesterol and low-density lipoprotein levels were also measured. Adv36 positivity was determined to be 27·1% and 6% in obese and non-obese children and 17·5% and 4% in obese and non-obese adults, respectively. There was no difference with regard to total cholesterol, low-density lipoprotein, triglyceride, tumour-necrosis-factor-alpha and interleukin-6 levels (P > 0·05). However, there was a significant difference between groups in terms of leptin levels (P obese children and adults. Our results showed that Adv36 may be an obesity agent for both adults and children, parallel with current literature data. However, the available data on a possible relationship between Adv36 infection and obesity both in children and adults do not completely solve the problem.

    To determine the prevalence of the HIV sero positivity in general paediatric emergency admissions at Kenyatta National Hospital, 552 children were studied systematically for four months in 1991. A clinical history was taken and physical examination conducted. The HIV status was determined by use of organon Teknika's Vironostika viral lysate assay for initial two screenings and then a Behring's enzygnost and anti HIV synthetic peptide assay as a confirmatory assay. Seventy (12.7%) of all the children studied were HIV positive, the mean age of the HIV -positive children was 17.5 months while that of total study population was 23.5 months. HIV seropositivity was not associated with history or parental injections. No haemophilia patient was recruited during the study period, and of all the 18 sicklers recruited, none was HIV positive despite multiple blood transfusions. The WHO paediatric Aids Case definition criteria had moderately low sensitivity (55.7%), high specificity (85.9%) and low positive predictive value (36.4%). This was in agreement with observations noted in earlier studies in East and Central Africa

    Rhodotorula species may be responsible for systemic infection in immunocompromised patients. Meningitis by Rhodotorula species in human immunodeficiency virus (HIV) infected persons has been reported previously. We report a case of meningitis caused by Rhodotorula mucilaginosa in a 36-year-old HIV seropositive male patient who presented with fever, altered sensorium and features of meningeal irritation i.e. neck rigidity. The Cerebrospinal fluid (CSF) cell counts were high, showing 150 cells/mm3, with 60% lymphocytes and 40% polymorphs, and protein content of 100 mg%; glucose was 60 mg%. The diagnosis was confirmed by culture on Sabouraud's Dextrose agar. The patient was treated successfully with intensive Amphotericin B (1 mg/kg), for two weeks, followed by oral Itraconazole (400 mg daily), for a period of two months. The patient was started on anti retroviral therapy. He did not show any relapse of the symptoms when the last follow up was done six months after the date of discharge. PMID:19893682

    Full Text Available The aim of this study was to analyse the clinical, epidemiological and bacteriological features present in 60 pulmonary tuberculosis patients who were also infected with human immunodeficiency virus (HIV and to compare these with 120 TB patients who were not infected with HIV. The patients with pulmonary tuberculosis and HIV coinfection were mostly male (p = 0.001, showed a higher frequency of weight loss >10 kilos (p <0.001, had a higher rate of non-reaction result to the tuberculin skin test (p <0.001, a higher frequency of negative sputum smear examination for acid-fast bacilli (p = 0.001 and negative sputum culture for Mycobacterium tuberculosis (p = 0.001. Treatment failure was more common in those who were HIV positive (p <0.000. No higher frequency of resistance to antituberculosis drugs was found to be associated with TB/HIV coinfection (p = 0.407. Association between extrapulmonary and pulmonary tuberculosis was more frequent in those seropositive to HIV than those without HIV virus, 30% and 1.6% respectively. These findings showed a predominance of atypical clinical laboratory features in co-infected patients, and suggest that health care personnel should consider the possibility this diagnosis.

    Full Text Available Cluster differentiation 4 (CD4 count estimation, which is not readily available in most resource poor settings in Nigeria, is an important indexdetermining commencement of antiretroviral therapy (ART. It is imperative for physicians who come in contact with these patients in such settings to recognize other parameters to evaluate these patients. The clinical correlates of diarrhea and gut parasites among human immunodeficiency virus (HIV-seropositive patients attending our special treatment clinic were studied. Three hundred and forty consenting HIV-positive adult subjects were enrolled. Their stool and blood specimens were collected for a period of three months. Stool samples were analyzed for the presence of diarrhea and gut parasites. The patients were clinically evaluated by physical examination for the presence of pallor, dehydration, oral thrush, wasting lymphadenopathy, dermatitis, skin hyperpigmentation, and finger clubbing. Participants with diarrhea represented 14.1% of the population, while 21.5% harbored one or more parasites. In the subjects with diarrhea, 14.6% harbored gut parasites. The presence of diarrhea was associated with a low CD4 count. Clinically, oral thrush, wasting, and rashes were more reliable predictors of low CD4 count levels; whereas, the presence of pallor, dehydration, wasting, and rashes correlated with the presence of diarrhea. HIV patients presenting with pallor, dehydration, wasting, and rashes should be evaluated for the presence of diarrhea. The clinical variables associated with low CD4 count in this study may guide commencing antiretroviral therapy in resource poor settings.

    2014-01-01

    With growing numbers of HIV-seropositive (HIV+) women of child-bearing age and increased access to effective clinical protocols for preventing mother-to-child transmission (MTCT) of HIV, mental health-related factors have become increasingly relevant due to their potential to affect the women’s quality of life, obstetric outcomes and risk of MTCT. This review synthesizes evidence from 53 peer-reviewed publications examining mental health-related variables in pregnant and postpartum HIV+ women. The presentation of results is organized by the level of socioeconomic resources in the countries where studies were conducted (i.e., high-, middle-, and low-income countries). It is concluded that psychiatric symptoms, particularly depression, and mental health vulnerabilities (e.g., inadequate coping skills) are widespread among pregnant HIV+ women globally and have a potential to affect psychological well-being, quality of life and salient clinical outcomes. The current body of evidence provides rationale for developing and evaluating clinical and structural interventions aimed at improving mental health outcomes and their clinical correlates in pregnant HIV+ women.

    Bovine brucellosis was first reported in Peninsular Malaysia in 1950. A subsequent survey conducted in the country revealed that the disease was widespread. Current knowledge on the potential risk factors for brucellosis occurrence on cattle farms in Malaysia is lacking. Therefore, we conducted a case-control study to identify the potential herd-level risk factors for bovine brucellosis occurrence in four states in the country, namely Kelantan, Pahang, Selangor and Negeri Sembilan. Thirty-five cases and 36 controls of herds were selected where data on farm management, biosecurity, medical history and public health were collected. Multivariable logistic regression identified that Brucella seropositive herds were more likely to; have some interaction with wildlife (OR 8.9, 95% CI = 1.59-50.05); originated from farms where multiple species such as buffalo/others (OR 41.8, 95% CI = 3.94-443.19) and goat/sheep (OR 8.9, 95%Cl = 1.10-71.83) were reared, practice extensive production system (OR 13.6, 95% CI 1.31-140.24) and have had episodes of abortion in the past (OR 51.8, 95% CI = 4.54-590.90) when compared to seronegative herds. Considering the lack of information on the epidemiology of bovine brucellosis in peninsular Malaysia and absence of information on preventing the inception or spread of the disease, this report could contribute to the on-going area-wise national brucellosis eradication program.

    Full Text Available OBJECTIVE: To identify risk factors associated with hepatitis C virus (HCV seropositivity in human immunodeficiency virus (HIV-infected patients. METHODS: A paired case-control study adjusted by age and gender was conducted. It included adults coinfected with HIV and HCV (cases and HIV mono-infected subjects (controls using non-probability sampling. Data were collected through interviews and review of medical records. The chi-square test was used for comparing categorical variables and the Student’s t-test or Wilcoxon (Mann-Whitney U test for continuous variables. Confidence intervals (95% were estimated along with crude and adjusted odds ratios using conditional logistic regression. RESULTS: A total of 165 patients were surveyed, including 55 cases and 110 controls. The mean age was 43.6 ± 8.4 years, ranging from 19 to 64 years; 70.9% were male. Independent risk factors for HIV/HCV coinfection were education (up to eight years of schooling; age at first intercourse < 15 years; having undergone tattooing; blood transfusion; and use of injecting drugs. CONCLUSIONS: Low level of education, early age at first sexual intercourse, tattooing, blood transfusions, and sharing needles and other drug injection equipment were factors that increased the risk of HIV/HCV coinfection. The results from this research can be compared with similar data from other regions to help direct preventive and educational efforts targeting people living with HIV.

    The objectives of this study were to assess the heterogeneities of estimates and to estimate the seroprevalence of brucellosis in animals and humans in Ethiopia. Data from 70 studies covering 75879 animals and 2223 humans were extracted. Rose Bengal Plate Test (RBPT) and Complement Fixation Test (CFT) in series were the most frequently used serological tests. A random effects model was used to calculate pooled prevalence estimates. The overall True Prevalence of brucellosis seropositivity in goats and sheep were estimated at 5.3% (95%CI = 3.5, 7.5) and 2.7% (95%CI = 1.8, 3.4), respectively, and 2.9% for each of camels and cattle. The prevalence was higher in post-pubertal than in pre-pubertal animals (OR = 3.1, 95% CI = 2.6, 3.7) and in the pastoral than in the mixed crop-livestock production system (OR = 2.8, 95%CI = 2.5, 3.2). The incidence rates of brucellosis in humans of pastoral and sedentary system origins were estimated at 160 and 28 per 100 000 person years, respectively. The seroprevalence of brucellosis is higher in goats than in other species. Its occurrence is evocative of its importance in the country in general and in the pastoral system in particular. Public awareness creation could reduce the transmission of Brucella spp. from animals to humans and the potential of livestock vaccination as a means of control of brucellosis needs to be assessed.

    OBJECTIVE To estimate seroprevalences for FeLV antigen and anti-FIV antibody and risk factors for seropositivity among cats in the United States and Canada. DESIGN Cross-sectional study. ANIMALS 62,301 cats tested at 1,396 veterinary clinics (n = 45,406) and 127 animal shelters (16,895). PROCEDURES Blood samples were tested with a point-of-care ELISA for FeLV antigen and anti-FIV antibody. Seroprevalence was estimated, and risk factors for seropositivity were evaluated with bivariate and multivariable mixed-model logistic regression analyses adjusted for within-clinic or within-shelter dependencies. RESULTS Overall, seroprevalence was 3.1% for FeLV antigen and 3.6% for anti-FIV antibody. Adult age, outdoor access, clinical disease, and being a sexually intact male were risk factors for seropositivity for each virus. Odds of seropositivity for each virus were greater for cats tested in clinics than for those tested in shelters. Of 1,611 cats with oral disease, 76 (4.7%) and 157 (9.7%) were seropositive for FeLV and FIV, respectively. Of 4,835 cats with respiratory disease, 385 (8.0%) were seropositive for FeLV and 308 (6.4%) were seropositive for FIV. Of 1,983 cats with abscesses or bite wounds, 110 (5.5%) and 247 (12.5%) were seropositive for FeLV and FIV, respectively. Overall, 2,368 of 17,041 (13.9%) unhealthy cats were seropositive for either or both viruses, compared with 1,621 of 45,260 (3.6%) healthy cats. CONCLUSIONS AND CLINICAL RELEVANCE Seroprevalences for FeLV antigen and anti-FIV antibody were similar to those reported in previous studies over the past decade. Taken together, these results indicated a need to improve compliance with existing guidelines for management of feline retroviruses.

    This interview study, the initial qualitative phase of a larger mixed methods HIV prevention study focused on Black heterosexual men, used intersectionality as a theoretical framework to explore: (1) How a sample of Black heterosexual men describe and experience the multiple intersections of race, gender, and SES; and (2) How these descriptions reflected interlocking systems of social inequality for Black men at the social-structural level. Participants were 30 predominantly low-income self-identified Black heterosexual men between the ages of 18 and 44. Analyses highlighted four themes that demonstrate how participants' individual-level experiences as Black men reflect macro social-structural inequality: (1) racial discrimination and microaggressions; (2) unemployment; (3) incarceration; and (4) police surveillance and harassment. We discuss the study's findings within the context of social-structural factors that disproportionately and adversely impact Black men. We also highlight the implications of the intersectionality perspective for HIV prevention research and interventions for Black heterosexual men.

    Five studies examined the hypothesis that heterosexual men, but not heterosexual women, endorse negative attitudes toward homosexuality (i.e., sexual prejudice) in order to maintain a positive gender-related identity that is unambiguously different from a homosexual identity. Studies 1 and 2 showed that men's (but not women's) gender self-esteem (but not personal self-esteem) was positively related to sexual prejudice: The more positive heterosexual men's gender self-esteem, the more negative their attitude toward homosexuality. Studies 3 and 4 showed that this link appears specifically among men motivated to maintain psychological distance from gay men. Study 5 experimentally manipulated the perceived biological differences between homosexual and heterosexual men. The previously observed link between men's gender self-esteem and sexual prejudice appeared in the control and no-differences conditions but disappeared in the differences condition. These findings are discussed in terms of men's attitudes as a defensive function against threat to masculinity.

  17. Narcissism and self-esteem among homosexual and heterosexual male students.

    According to orthodox psychoanalytical theory, narcissism and homosexuality are strongly associated. This association played a major role in pathologizing homosexuality. The present study compared self-esteem and two measures of narcissism among 90 homosexual and 109 heterosexual male students, who filled in a demographic questionnaire, Rosenberg's Self-Esteem Scale, the Narcissistic Personality Inventory, and the Pathological Narcissism Inventory, which addresses both grandiose and vulnerable subtypes of narcissism. The hypothesis, which is based on the Freudian connection between narcissism and homosexuality, is supported by the results, indicating that the homosexual students score higher in both measures of narcissism and lower on the self-esteem measure, compared to their heterosexual counterparts. Intra-psychic, as well as environmental, interpretations of the results are suggested in the discussion.

    This research assessed the correlates of homophobia and transphobia in heterosexual and homosexual individuals, based on a theory of different sources of perceived symbolic threat to social status. Compared to 310 heterosexual college students, a sample of 30 gay male and 30 lesbian college students scored lower on homophobia, transphobia, and religious fundamentalism. Mean gender differences were smaller for gay men and lesbians for homophobia, aggressiveness, benevolent sexism, masculinity, and femininity. Fundamentalism, right-wing authoritarianism, and hostile and benevolent sexism were correlated only with homophobia in lesbians, whereas fundamentalism and authoritarianism were correlated only with transphobia in gay men. Correlates of internalized homophobia were different than those found for homophobia and transphobia, which was discussed in terms of gender differences in threats to status based on sexual orientation versus gender identity.

    Self-identified lesbian, gay male, and bisexual (LGB) individuals were recruited via convenience sampling, and they in turn recruited their siblings (79% heterosexual, 19% LGB). The resulting sample of 533 heterosexual, 558 lesbian or gay male, and 163 bisexual participants was compared on mental health variables and their use of mental health services. Multilevel modeling analyses revealed that sexual orientation predicted suicidal ideation, suicide attempts, self-injurious behavior, use of psychotherapy, and use of psychiatric medications over and above the effects of family adjustment. Sexual orientation was unrelated to current psychological distress, psychiatric hospitalizations, and self-esteem. This is the 1st study to model family effects on the mental health of LGB participants and their siblings. Copyright (c) 2005 APA, all rights reserved.

    Over the past decades, the decline in Black marriages and the upsurge of never-married Blacks have stimulated much theoretical focus, but researchers conducted few studies on never-married heterosexual Black adults' coupling unions. Guided by an integrated framework of Africana womanism and symbolic interactionism, this qualitative hermeneutic phenomenological study used comprehensive individual interviews to explore the experiences of 26 never-married heterosexual Black men and women between the ages 25 and 35 about their attempts to cultivate and maintain intimate romantic relationships as well as their desire for marriage. Findings revealed mixed emotions from participants' lived experiences in developing and sustaining romantic relationships. Clinical implications highlighted the need to effectively attend to Black romantic relationships and experiences in their sociohistorical and sociocultural contexts. © 2017 American Association for Marriage and Family Therapy.

    Full Text Available HIV-seropositive persons are at increased risk of methicillin-resistant Staphylococcus aureus (MRSA. Genital ulcerative disease and sexually transmitted infection with subsequent MRSA infection in HIV-seropositive persons have been documented only once. We report a case of a 44-year-old man who presented to the Infectious Diseases Institute, Kampala, Uganda, with chronic genital ulcer disease and who subsequently developed MRSA urethritis and bacteraemia. This case also demonstrates that persistent genital ulcer disease in HIV-seropositive persons may be as a result of concurrent MRSA infection.

    Here, I explore the efficacy of straight teacher allies, the importance of understanding straight privilege, and the significance of radical heterosexuality for straight people doing LGBTQ activism. Relying on queer theory and decolonizing/Indigenous queer theory, I argue that it is necessary for straight teachers to acknowledge their straight privilege in order to challenge homophobia's companions: heterosexism and heteronormativity. In addressing the latter two covert forms of oppression in schools, teachers and students could shift into deeper, more effective resistance measures.

    The current longitudinal study examined patterns and predictors of parent-reported gender-typed play behavior in adopted boys and girls in lesbian, gay, and heterosexual 2-parent families, across early childhood (Mage = 2.82 to 6.06 years). Specifically, using a sample of 181 couples (56 lesbian couples, 48 gay male couples, and 77 heterosexual couples), we examined parent reports of children's gender-typed play behavior on the Pre-School Activities Inventory (PSAI; Golombok & Rust, 1993) at 3 time points (mean age = 2.82 years at T1, 3.93 years at T2, and 6.06 years at T3). Family structure variables (i.e., parents' gender and sexual orientation; children's gender and sibling status) were included as predictors. At T1, according to parent reports, children in lesbian-parent families had less gender-differentiated behavior (boys were less masculine, girls were less feminine) than children in heterosexual- and gay-parent families, whereas the degree of gender differentiation did not differ between heterosexual- versus gay-parent families. Findings from a Common Fate Growth Model (Ledermann & Macho, 2014) revealed that, regardless of family type, the parent-reported gender-typed behavior of boys, but not girls, significantly changed over time (i.e., boys' behavior became more masculine). Our findings have implications for researchers who study gender development in children and adolescents, particularly those who are being raised by 2 mothers or 2 fathers.

    Full Text Available We assessed the proportion of and socio-ecological factors associated with ever having had sex with female sex workers (FSWs among heterosexual adolescents. We also described the characteristics of the adolescents who reported inconsistent condom use with FSWs.This is a cross-sectional study (response rate: 73% of 300 heterosexually active male adolescents of 16 to 19 years attending a national STI clinic in Singapore between 2009 and 2014. We assessed the ecological factors (individual, parental, peer, school and medial influences and sexual risk behaviors using a self-reported questionnaire. Poisson regression was used to obtain the adjusted prevalence ratios (aPR and confidence intervals (CI.The proportion of heterosexual male adolescents who had ever had sex with FSWs was 39%.

Lifetime inconsistent condom use with FSWs was 30%.A significant proportion of heterosexual male adolescents attending the public STI clinic had ever had sex with FSWs. A targeted intervention that addresses different levels of influence to this behavior is needed. This is even more so because a considerable proportion of adolescents reported inconsistent condom use with FSWs, who may serve as a bridge of STI transmission to the community. National surveys on adolescent health should include the assessment of frequency of commercial sex visits and condom use with FSWs for long-term monitoring and surveillance.

  5. Molecular phylodynamics of the heterosexual HIV epidemic in the United Kingdom.

    Full Text Available The heterosexual risk group has become the largest HIV infected group in the United Kingdom during the last 10 years, but little is known of the network structure and dynamics of viral transmission in this group. The overwhelming majority of UK heterosexual infections are of non-B HIV subtypes, indicating viruses originating among immigrants from sub-Saharan Africa. The high rate of HIV evolution, combined with the availability of a very high density sample of viral sequences from routine clinical care has allowed the phylodynamics of the epidemic to be investigated for the first time. Sequences of the viral protease and partial reverse transcriptase coding regions from 11,071 patients infected with HIV of non-B subtypes were studied. Of these, 2774 were closely linked to at least one other sequence by nucleotide distance. Including the closest sequences from the global HIV database identified 296 individuals that were in UK-based groups of 3 or more individuals. There were a total of 8 UK-based clusters of 10 or more, comprising 143/2774 (5% individuals, much lower than the figure of 25% obtained earlier for men who have sex with men (MSM. Sample dates were incorporated into relaxed clock phylogenetic analyses to estimate the dates of internal nodes. From the resulting time-resolved phylogenies, the internode lengths, used as estimates of maximum transmission intervals, had a median of 27 months overall, over twice as long as obtained for MSM (14 months, with only 2% of transmissions occurring in the first 6 months after infection. This phylodynamic analysis of non-B subtype HIV sequences representing over 40% of the estimated UK HIV-infected heterosexual population has revealed heterosexual HIV transmission in the UK is clustered, but on average in smaller groups and is transmitted with slower dynamics than among MSM. More effective intervention to restrict the epidemic may therefore be feasible, given effective diagnosis programmes.

    Chlamydia infections are common in both men and women, are often asymptomatic and can cause serious complications. Repeat testing in high-risk groups is therefore indicated. In the Netherlands, guidelines on repeat chlamydia testing differ between testing facilities, and knowledge on repeat testing behaviour is limited. Here, we analyse the current repeat testing behaviour of heterosexual STI clinic visitors, and aim to identify groups for which repeat testing advice could be advantageous. Longitudinal surveillance data from all Dutch STI outpatient clinics were used, which included all STI clinic consultations carried out among heterosexual men and women between June 2014 and December 2015. Repeat testing was defined as returning to the same STI clinic between 35 days and 12 months after initial consultation. We calculated chlamydia positivity at repeat test stratified by initial test result and time between consultations. Logistic regression analyses were used to identify predictors of repeat testing, and predictors of having a chlamydia positive repeat test. In total, 140,486 consultations in 75,487 women and 46,286 men were available for analyses. Overall, 15.4% of women and 11.1% of men returned to the STI clinic within the study period. Highest chlamydia positivity at repeat test was seen 3-5 months after initial positive test. Among both women and men, repeat testing was associated with non-Western ethnicity, having had more than two sex partners in the past 6 months, reporting STI symptoms, having a history of STI, and having a chlamydia positive initial test. Among repeat testers, chlamydia positive repeat test was most strongly associated with younger age, followed by a chlamydia positive initial test. Repeat testing most often resulted in a positive test result among young heterosexuals (<25) and heterosexuals of any age with a chlamydia infection at the initial consultation. Further efforts are needed to determine optimal repeat testing strategies.

    While gendered sexual scripts are hegemonic at the cultural level, research suggests they may be less so at dyadic and individual levels. Understanding “disjunctures” between sexual scripts at different levels holds promise for illuminating mechanisms through which sexual scripts can change. Through interviews with 44 heterosexually active men and women aged 18-25, we delineated ways young people grappled with culture-level scripts for sexuality and relationships. Findings suggest that althou...

    The classification of non-heterosexuality has changed considerably over the past century. Once considered as medical conditions attracting legal complications and serious social stigma, expressions of non-heterosexuality are now broadly considered to be normal variations of human sexuality. The historical inclusion of homosexuality in the psychiatric literature may still have implications for how sexual orientation is viewed today, including the ongoing treatment of homosexuality as an illnes...

    to determine the prevalence and type of intestinal parasites in HIV infected and uninfected patients with diarrhea. A cross-sectional study was conducted at Gondar University hospital, Northwest Ethiopia, between March 2003 and October 2004. A total 312 consecutive diarrheic patients were included in the study. Stool specimens were collected and examined for intestinal parasites following direct, formol-ether concentration and modified acid fast staining methods. Among the patients, 63.8% were found to be HIV seropositive. The prevalence of intestinal parasites in HIV seropositive and seronegative diarrheic patients was 30.6% and 33.6%, respectively. The most prevalent parasites were Strongyoides stercoralis (9.0%) and Entamoeba histolytica (8.3%) followed by Ascaris lumbricoides (5.4%) and Cryptosporidium species (5. 1%). The prevalence of intestinal parasites in diarrheic patients was very high. Institution of appropriate intervention measures are needed to reduce morbidity in such patients.

    Studies of subjective and genital sexual arousal in monosexual (i.e. heterosexual and homosexual) men have repeatedly found that erotic stimuli depicting men’s preferred sex produce strong responses, whereas erotic stimuli depicting the other sex produce much weaker responses. Inconsistent results have previously been obtained in bisexual men, who have sometimes demonstrated distinctly bisexual responses, but other times demonstrated patterns more similar to those observed in monosexual men. We used fMRI to investigate neural correlates of responses to erotic pictures and videos in heterosexual, bisexual, and homosexual men, ages 25–50. Sixty participants were included in video analyses, and 62 were included in picture analyses. We focused on the ventral striatum (VS), due to its association with incentive motivation. Patterns were consistent with sexual orientation, with heterosexual and homosexual men showing female-favoring and male-favoring responses, respectively. Bisexual men tended to show less differentiation between male and female stimuli. Consistent patterns were observed in the whole brain, including the VS, and also in additional regions such as occipitotemporal, anterior cingulate, and orbitofrontal cortices. This study extends previous findings of gender-specific neural responses in monosexual men, and provides initial evidence for distinct brain activity patterns in bisexual men. PMID:28145518

    2009-06-01

    The role of childhood gender role nonconformity (CGNC) and childhood harassment (CH) in explaining suicidality (suicide ideation, aborted suicide attempts, and suicide attempts) was examined in a sample of 142 lesbian, gay, and bisexual (LGB) adults and 148 heterosexual adults in Austria. Current and previous suicidality, CGNC, and CH were significantly greater in LGB participants compared to heterosexual participants. After controlling for CGNC, the effect of sexual orientation on CH diminished. CGNC correlated significantly with current suicidality in the LGB but not in the heterosexual group, and only non-significant correlations were found for CGNC with previous suicidality. Controlling for CH and CGNC diminished the effect of sexual orientation on current suicidality. Bayesian multivariate analysis indicated that current suicidality, but not previous suicidality, depended directly on CGNC. CH and CGNC are likely implicated in the elevated levels of current suicidality among adult LGB participants. As for previous suicidality, the negative impact of CGNC on suicidality might be overshadowed by stress issues affecting sexual minorities around coming out. The association of CGNC with current suicidality suggests an enduring effect of CGNC on the mental health and suicide risk of LGB individuals.

    Bellatorre, Anna; Muennig, Peter

    2014-01-01

    Objectives. We determined whether individuals who harbor antigay prejudice experience elevated mortality risk. Methods. Data on heterosexual sexual orientation (n = 20 226, aged 18–89 years), antigay attitudes, and mortality risk factors came from the General Social Survey, which was linked to mortality data from the National Death Index (1988–2008). We used Cox proportional hazard models to examine whether antigay prejudice was associated with mortality risk among heterosexuals. Results. Heterosexuals who reported higher levels of antigay prejudice had higher mortality risk than those who reported lower levels (hazard ratio [HR] = 1.25; 95% confidence interval [CI] = 1.09, 1.42), with control for multiple risk factors for mortality, including demographics, socioeconomic status, and fair or poor self-rated health. This result translates into a life expectancy difference of approximately 2.5 years (95% CI = 1.0, 4.0 years) between individuals with high versus low levels of antigay prejudice. Furthermore, in sensitivity analyses, antigay prejudice was specifically associated with increased risk of cardiovascular-related causes of death in fully adjusted models (HR = 1.29; 95% CI = 1.04, 1.60). Conclusions. The findings contribute to a growing body of research suggesting that reducing prejudice may improve the health of both minority and majority populations. PMID:24328664

    2015-01-01

    Little work has examined relationship dissolution or divorce in adoptive parents or same-sex parent couples. The current study examined predictors of relationship dissolution across the first 5 years of parenthood among a sample of heterosexual, lesbian, and gay male adoptive couples. Of the 190 couples in the study, 15 (7.9%) dissolved their relationships during the first 5 years of adoptive parenthood. Specifically, 7 of 57 lesbian couples (12.3%), 1 of 49 gay male couples (2.0%), and 7 of 84 heterosexual couples (8.3%) dissolved their unions. Results of our logistic regression analysis revealed that the odds of relationship dissolution were significantly higher for (a) couples who adopted a non-infant (i.e., older) child); (b) participants who reported feeling less prepared for the adoption, three months post-adoptive placement; and (c) couples in which both partners reported very low, or very high, pre-adoption levels of relationship maintenance behaviors. Findings have implications for adoption professionals seeking to support same-sex and heterosexual prospective adopters, as well as societal debates and policy regarding same-sex relationships and parenting.

    Few studies demonstrated neural circuits related to disgust were influenced by internal sexual orientation in male. Here we used fMRI to study the neural responses to disgust in homosexual and heterosexual men to investigate that issue. Thirty-two healthy male volunteers (sixteen homosexual and sixteen heterosexual) were scanned while viewing alternating blocks of three types of erotic film: heterosexual couples (F-M), male homosexual couples (M-M), and female homosexual couples (F-F) engaged in sexual activity. All the participants rated their level of disgust and sexual arousal as well. The F-F and M-M stimuli induced disgust in homosexual and heterosexual men, respectively. The common activations related to disgusting stimuli included: bilateral frontal gyrus and occipital gyrus, right middle temporal gyrus, left superior temporal gyrus, right cerebellum, and right thalamus. Homosexual men had greater neural responses in the left medial frontal gyrus than did heterosexual men to the sexual disgusting stimuli; in contrast, heterosexual men showed significantly greater activation than homosexual men in the left cuneus. ROI analysis showed that negative correlation were found between the magnitude of MRI signals in the left medial frontal gyrus and scores of disgust in homosexual subjects (pmen.

    We previously reported that trait aggression, proposed as an endophenotype for suicidal behavior, is positively associated with Toxoplasma gondii ( T. gondii ) seropositivity in females, but not in males. Additionally, older males seropositive for T. gondii had lower scores on measures of trait aggression, including self-aggression. Trait aggression may be influenced by dopaminergic signaling, which is known to be moderated by gender and age, and potentially enhanced in T. gondii positives through the intrinsic production of dopamine by the microorganism. Therefore, we investigated associations between trait aggression and interactions between T. gondii enzyme-linked immunoabsorbant assay (ELISA) IgG titer-determined seropositivity and high-performance liquid chromatography- (HPLC-) measured blood levels of dopamine precursors phenylalanine (Phe), tyrosine (Tyr), and their ratio in a sample of 1000 psychiatrically healthy participants. Aggressive traits were assessed using the questionnaire for measuring factors of aggression (FAF), the German version of the Buss-Durkee hostility questionnaire. We found that 1) the decrease in trait aggression scores in T. gondii -positive older males was only present in individuals with a low Phe:Tyr ratio, and 2) that there was a positive correlation between Phe:Tyr ratio and total aggression and selected subscales of aggression in T. gondii -positive males, but not in T. gondii -negative males. These findings point toward a gender-specific reciprocal moderation by Phe:Tyr ratio and T. gondii seropositivity of their associations with aggression scores, and lead to experimental interventions geared to manipulating levels of dopamine precursors in selected T. gondii positive individuals with increased propensity for aggression.

    Donkeys (Equus asinus) are used as both companion and working animals throughout the world and in some countries, their meat and milk are used for human consumption. Here we report the first serological survey of Toxoplasma gondii in donkeys in the United States. Serum samples from 373 donkeys from eight farms in five states were tested for T. gondii antibodies by the modified agglutination test (MAT). Twenty-four of 373 (6.4%) of donkeys were seropositive, with MAT titers ranging from 25 to ≥ 200. All seropositive donkeys were Miniature breed. Seropositivity prevalence was 7.0% in female donkeys (20/282) and 4.1% in male donkeys (4/91). No donkeys less than 24 months of age (129) were seropositive, suggesting postnatal transmission of infection. Domestic cats were present on six of the eight farms. Three cats from one farm had MAT titers of 200. Viable T. gondii was isolated from the hearts of two cats, but not from brain tissues. Genotyping of isolate DNA extracted from culture-derived tachyzoites using 10 PCR-restriction fragment length polymorphism (RFLP) markers (SAG1, SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, PK1, L358 and Apico loci) revealed that both isolates were clonal Type II (ToxoDB PCR-RFLP genotype #1). This is the first serological survey for T. gondii in donkeys in the United States, and suggests that donkey milk and meat should be considered as a potential source for human infection. The role of barn cats in the transmission of T. gondii to donkeys on farms warrents further investigation. Copyright © 2013 Elsevier B.V. All rights reserved.

    Full Text Available The aim of this study was to evaluate associations between seropositivity for IgG and IgM anti-Toxoplasma gondii antibodies and socio-economic and environmental variables in pregnant women of Londrina, state of Paraná, Brazil. We interviewed 492 pregnant women, each of whom answered an epidemiological questionnaire, and collected blood samples for measurement of IgG and IgM anti-T. gondii antibodies by chemiluminescence. A confirmatory diagnosis of acute infection was made by an IgG avidity test. Titres of specific IgG anti-T. gondii were obtained by IFAT. Seropositivity for IgG anti-T. gondii antibodies was observed in 242 women (49.2% and, of these, six pregnant women (1.2% showed seropositivity for IgM. Age group, level of education, per capita income, presence of a cat in the house and a habit of eating green vegetables were all factors associated with a greater chance of infection with T. gondii. This study showed that 250 (50.8% pregnant women were susceptible to T. gondii and considered to be at high risk for toxoplasmosis during pregnancy. Based on the results obtained, is critical to establish a program of health surveillance for toxoplasmosis, in order to contribute to diagnosis and early treatment during the prenatal period. It is also necessary to introduce measures to prevent the Toxoplasma infection in seronegative pregnant women.

    To assess the proportion of seropositivity of Hepatitis C amongst the prison inmates in the jails of Sindh. A cross sectional HCV seroprevalence survey was done at 14 out of 19 prisons in the Sindh province from November 2008 to January 2009. A team of Pathologist, phlebotomist and laboratory technician took the blood sample of the inmates inside the correctional facility; the blood was centrifuged at the spot and brought back to the pathology laboratory on same day in cold chain i.e. a temperature-controlled supply chain. Serum was analyzed on 3rd generation ELISA for HCV antibodies. Standard ethical considerations were properly followed. Atotal of 9508 prison inmates were approached. Refusal rate was 20%. Remaining, 7539 prisoners were screened at 14 out of 19 jails in Sindh. HCV antibody positive were 965 making the proportion of seropositivity 12.8% (95% C.I. 8.92% - 12.92%). Higher seropositivity in the jails of northern Sindh jails was identified. Hepatitis C prevalence in the prison population of Sindh is higher than the national prevalence of 4.9% amongst general population. However it is lower than that reported from correctional facilities of developed countries. Hepatitis prevention and control activities in the correctional facilities of Pakistan need to be institutionalized (JPMA 60:476; 2010).

    Full Text Available Abstract Background Since 1999, field evidence of transplacental infection by porcine circovirus type 2 (PCV2 and reproductive failure has been reported in pigs. The objective of this study was to evaluate the clinical and pathological consequences of PCV2 infection in conventional PCV2-seropositive gilts by insemination with PCV2b-spiked semen. Results Six PCV2 seropositive gilts were inseminated with PCV2b-supplemented semen (infected and three animals with semen and cell culture medium (controls. Only three out of the six infected animals were pregnant by ultrasonography on day 29 after insemination, while two out of the three controls were pregnant. One control gilt aborted on day 23 after insemination but not due to PVC2. Viraemia was demonstrated in four out of six infected and in one control gilt that became infected with PCV2a. Anti-PCV2 antibody titres showed dynamic variations in the infected group throughout the study. Among infected gilts, the animal with the lowest anti-PCV2 titre (1/100 at the beginning of the experiment and another that reached a similar low value during the experiment showed evident seroconversion over time and had also PCV2 positive foetuses. One placenta displayed mild focal necrosis of the chorionic epithelium positively stained by immunohistochemistry for PCV2 antigen. Conclusions PCV2-seropositive gilts can be infected with PCV2 after intrauterine exposure and low maternal antibody titre may increase the probability of a foetal infection.

    Full Text Available A large number of dead bodies are referred to forensic autopsy halls for medicolegal examination. They can be a source of transmission of infectious diseases through direct contact or autopsy tools. The main aim of this study was to estimate the virus infection rates in the dead bodies. One thousand consecutive dead bodies that had been referred to autopsy hall of Legal Medicine Bureau of Tehran, Iran, during 2016, were included. The blood samples were analyzed in the laboratory for detection of HBs Ag, HBs Ab, HIV Ab, and HCV Ab, after providing informed consent from legal next of kin of the dead bodies. The general characteristics of the dead bodies were also collected by a checklist. Forty-seven cases of HIV seropositivity, 80 cases of HBs Ag seropositivity, and 97 cases for HCV Ab seropositivity were found. Among them, 27 cases of HIV, 40 cases of anti-HBC positive, and 94 cases of RIBA testing positive for HCV were proved through confirmatory tests. In other words, 2.6% of the dead bodies were infected with HIV, 3.8% with HBV, and 9% with HCV. The total infection rate was 15.5%. This is a worrying risk for pathologist and autopsy technicians.

    Previous research shows that sexual minority women have higher rates of unintended pregnancy than heterosexual women, but has not considered the wide range of contraceptive method effectiveness when exploring this disparity. We examine contraceptive use effectiveness and desire for pregnancy prevention information among college women across sexual orientation identity as a risk factor for unintended pregnancy. Using the National College Health Assessment Fall-2015 dataset, restricted to women who reported engaging in vaginal sex and not wanting to be pregnant (N = 6,486), logistic regression models estimated the odds of contraceptive method effectiveness and desire for pregnancy prevention information by sexual orientation. Most women (57%) reported using a moderately effective contraceptive method (e.g., pill, patch, ring, shot) at last vaginal sex. Compared with heterosexual women, bisexual (adjusted odds ratio [aOR], 0.48; 95% confidence interval [CI], 0.37-0.62), lesbian (aOR, 0.03; 95% CI, 0.02-0.06), pansexual/queer (aOR, 0.38; 95% CI, 0.25-.56) and other (aOR, 0.50; 95% CI, 0.30-0.81) women were significantly less likely to have used a moderately effective method compared with no method. Only 9% of the sample used a highly effective method; asexual (aOR, 0.58; 95% CI, 0.37-0.92) and lesbian (aOR, 0.07; 95% CI, 0.03-0.20) women were significantly less likely than heterosexual women to have used these methods. Pansexual/queer and bisexual women were more likely than heterosexual women to desire pregnancy prevention information. Several groups of sexual minority women were less likely than heterosexual women to use highly or moderately effective contraceptive methods, putting them at increased risk for unintended pregnancy, but desired pregnancy prevention information. These findings bring attention to the importance of patient-centered sexual and reproductive care to reduce unintended pregnancy. Copyright © 2018 Jacobs Institute of Women's Health. Published

    Malignant lymphoma has become an increasingly recognized problem in African lions (Panthera leo). Eleven African lions (9 male and 2 female) with clinical signs and gross and microscopic lesions of malignant lymphoma were evaluated in this study. All animals were older adults, ranging in age from 14 to 19 years. Immunohistochemically, 10 of the 11 lions had T-cell lymphomas (CD3(+), CD79a(-)), and 1 lion was diagnosed with a B-cell lymphoma (CD3(-), CD79a(+)). The spleen appeared to be the primary site of neoplastic growth in all T-cell lymphomas, with involvement of the liver (6/11) and regional lymph nodes (5/11) also commonly observed. The B-cell lymphoma affected the peripheral lymph nodes, liver, and spleen. According to the current veterinary and human World Health Organization classification of hematopoietic neoplasms, T-cell lymphoma subtypes included peripheral T-cell lymphoma (4/11), precursor (acute) T-cell lymphoblastic lymphoma/leukemia (2/11), chronic T-cell lymphocytic lymphoma/leukemia (3/11), and T-zone lymphoma (1/11). The single B-cell lymphoma subtype was consistent with diffuse large B-cell lymphoma. Feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) testing by immunohistochemistry on sections of malignant lymphoma was negative for all 11 lions. One lion was seropositive for FeLV. In contrast to domestic and exotic cats, in which B-cell lymphomas are more common than T-cell lymphomas, African lions in this study had malignant lymphomas that were primarily of T-cell origin. Neither FeLV nor FIV, important causes of malignant lymphoma in domestic cats, seems to be significant in the pathogenesis of malignant lymphoma in African lions.

    Context Bullying is a known risk factor for suicidality, and suicide is the second leading cause of death for adolescents. Both are increased in sexual minority youth (SMY). As SMY are comprised of youth who self-identify as gay, lesbian, bisexual (GLB) or who have same-sex attractions or behaviors, our previous finding that different subgroups have different risks for suicidality is understandable. Given that the difference was along sexual identity lines (GLB vs heterosexual SMY), the analysis of bullying data in the same subgroups was felt to be important.Objective To compare the association of bullying and suicide among heterosexual students without same-sex attractions or behaviors, heterosexual students with same-sex attractions and behaviors, and students with gay, lesbian or bisexual (GLB) or unsure sexual identities.Design The 2004 Quebec Youth Risk Behavior Survey (QYRBS) questionnaire was based on the 2001 Center for Disease Control Youth Risk Behavior Survey, and included items assessing the three dimensions of sexual orientation (identity, attraction and behavior), health risk behaviors, experiences of harassment, and suicidal ideation, plans and attempts.Methods A total of 1852 students 14-18 years of age from 14 public and private high schools in Montréal Québec were surveyed anonymously during the 2004-2005 academic year.Main outcome measure Self reports of suicidal ideation, suicidal plan and suicide attempts in the last 12 months.Results In all, 117 students (6.3%) had a non-heterosexual identity (GLB or unsure) and 115 students (6.3%) had a heterosexual identity with same-sex attraction or behavior. Bullying occurred in 24% of heterosexual students without same-sex attraction or behavior, 32% of heterosexual students with same-sex attraction or behavior, and 48% of non-heterosexually identified students. In multivariable analysis, the common risk factors of age, gender, depressed mood, drug use, fighting, physical and sexual abuse, and

    Introduction: HIV-1 is transmitted through semen from men to their sexual partners. Genital infections can increase HIV-1 RNA shedding in semen, but shedding also occurs in the absence of typical pathogens. We hypothesized that higher bacterial concentrations in semen would be associated with higher HIV-1 RNA levels. Methods: We analyzed semen samples from 42 HIV-1–seropositive Kenyan men using quantitative polymerase chain reaction (PCR) to assess bacterial concentrations and real-time PCR to measure HIV-1 RNA levels. Generalized estimation equations were used to evaluate associations between these 2 measures. Broad-range 16S rRNA gene PCR with pyrosequencing was performed on a subset of 13 samples to assess bacterial community composition. Results: Bacteria were detected in 96.6% of 88 samples by quantitative PCR. Semen bacterial concentration and HIV-1 RNA levels were correlated 0.30 (P = 0.01). The association between bacterial concentration and HIV-1 RNA detection was not significant after adjustment for antiretroviral therapy (ART) (adjusted odds ratio: 1.27, 95% CI: 0.84 to 1.91). Factors associated with semen bacterial concentration included insertive anal sex (adjusted beta 0.92, 95% CI: 0.12 to 1.73) and ART use (adjusted beta: −0.77, 95% CI: −1.50 to 0.04). Among 13 samples with pyrosequencing data, Corynebacterium spp., Staphylococcus spp., and Streptococcus spp. were most frequently detected. Conclusion: Most of these HIV-1–infected men had bacteria in their semen. ART use was associated with undetectable semen HIV-1 RNA and lower semen bacterial concentrations, whereas insertive anal sex was associated with higher bacterial concentrations. Additional studies evaluating the relationship between semen bacteria, inflammation, mucosal immunity, and HIV-1 shedding are needed to understand implications for HIV-1 transmission. PMID:27861240

    Bovine brucellosis was first reported in Peninsular Malaysia in 1950. A subsequent survey conducted in the country revealed that the disease was widespread. Current knowledge on the potential risk factors for brucellosis occurrence on cattle farms in Malaysia is lacking. Therefore, we conducted a case-control study to identify the potential herd-level risk factors for bovine brucellosis occurrence in four states in the country, namely Kelantan, Pahang, Selangor and Negeri Sembilan. Thirty-five cases and 36 controls of herds were selected where data on farm management, biosecurity, medical history and public health were collected. Multivariable logistic regression identified that Brucella seropositive herds were more likely to; have some interaction with wildlife (OR 8.9, 95% CI = 1.59–50.05); originated from farms where multiple species such as buffalo/others (OR 41.8, 95% CI = 3.94–443.19) and goat/sheep (OR 8.9, 95%Cl = 1.10–71.83) were reared, practice extensive production system (OR 13.6, 95% CI 1.31–140.24) and have had episodes of abortion in the past (OR 51.8, 95% CI = 4.54–590.90) when compared to seronegative herds. Considering the lack of information on the epidemiology of bovine brucellosis in peninsular Malaysia and absence of information on preventing the inception or spread of the disease, this report could contribute to the on-going area-wise national brucellosis eradication program.

    Disorders associated with the hepatitis C virus (HCV) have been reported including cardiovascular, metabolic, and central nervous system diseases. Since chronic HCV infections may be curable, their identification as causal contributors to cardiovascular risk could offer new perspectives in the prevention of cardiovascular disease. The aim of this study is to investigate the association between HCV and aortic arch calcification (AAC) and corneal and conjunctival calcification (CCC) in maintenance hemodialysis (MHD) patients; further, we assessed the correlation of CCC with vascular calcification. A total of 100 patients undergoing hemodialysis (HD) in our hospital were included in this study. Patients underwent a complete ocular examination including intraocular pressure, and CCC was looked for by slit lamp and fundoscopy. CCC was graded according to modified Porter and Crombie classification system described by Tokuyama et al. Helical computerized tomographic chest examination was used to evaluate the grading of AAC. Demographic, hematological, biochemical, and dialysis-related data were obtained. There was significant difference between seropositive (n = 51) and seronegative patients (n = 49) regarding grading of AAC and CCC (P <0.001). Significant positive correlation was found between grading of CCC, AAC, age (P <0.001), duration on HD (P <0.001), HCV-antibody positivity (P <0.001), serum calcium level (P <0.001), serum phosphorus level (P <0.001), calcium × phosphorus product (P <0.001), and i-parathormone level (P < 0.001). In addition, CCC grading positively correlated with AAC. Our results suggest that patients undergoing HD infected with the HCV have high degree of CCC, AAC, and mineral metabolism disorder. The strong correlation between CCC and AAC indicates that CCC evaluation is an easy, fast, non-invasive method, and might be used as an indirect indicator to detect vascular calcification in patients undergoing MHD.

    A cross-sectional quantitative study of cutaneous bacterial and yeast flora at seven body sites in 99 human immunodeficiency virus-seropositive and 50 seronegative military personnel was performed. Statistically significant differences in carriage rates were only observed for Staphylococcus aureus on the foreheads of seropositive individuals. Seronegative individuals demonstrated staphylococcal carriage rates 1.3 to 2 times as great as those of historical controls (defined as healthy individuals not receiving any medications) at five of six body sites. We conclude that seropositive military personnel do not exhibit statistically significant elevations in densities and carriage rates of the microorganisms examined (except Staphylococcus aureus), relative to seronegative individuals. Seropositive individuals may be predisposed to staphylococcal carriage. The elevated staphylococcal carriage rates of military personnel undergoing basic training warrants a formal evaluation of the impact of training exercises on cutaneous flora. The information gained may serve to limit the spread of infection during training exercises and battlefield conditions. PMID:10970352

    Cervical cancer has become the most common cancer affecting women in Africa. Significantly, 85% of these annual deaths occur in the developing world, with the majority being middle-aged women. Research has shown that in sub-Saharan Africa, cervical cancer trends are on the rise in the past two decades because of HIV and this has resulted in an increase in cervical cancer cases among young women. However, little or no information exists that has shown that any of the available treatment methods are more effective than others when it comes to treating cervical cancer in HIV-seropositive women. The aim of this protocol is to offer a plan on how to systematically review cervical cancer treatment methods available for HIV-seropositive women in developing countries. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) statement was used to develop the protocol for the systematic review which will be reported in accordance with the PRISMA guidelines. A number of databases, Embase, MEDLINE, PubMed, CINAHL and Cochrane Library, will be searched for relevant studies, and citation and reference list tracking will be used to search for additional studies. Prospective and retrospective cohort studies, case-control, randomised controlled trials and cross-sectional studies that were carried out in and for the developing world will be eligible for inclusion. Peer-reviewed studies and grey literature examining cervical cancer treatment modalities in HIV-seropositive women will be included. Descriptive statistics and tables will be used to summarise results, and meta-analysis will be used where appropriate. The review findings will provide the current picture of the existing treatment methods being used to treat cervical cancer in HIV-seropositive women in developing countries. The findings might be used for the establishment of evidence-based guidelines for treatment of cervical cancer in seropositive women as well as prompt policy-makers and

    Neuromyelitis optica spectrum disorders (NMOSDs) are a group of rare inflammatory demyelinating disorders of the central nervous system. The identification of specific antibodies directed to aquaporin 4 (AQP4-IgG) led to the distinction from multiple sclerosis. However, up to 25% of the clinically diagnosed NMO patients are seronegative for AQP4-IgG. A subgroup of these patients might be identified by antibodies directed to myelin oligodendrocyte glycoprotein (MOG-IgG). Our objective was to investigate whether the clinical characteristics of these patients differ. Using a cell-based assay, samples of 61 AQP4-IgG seronegative patients and 41 AQP4-IgG seropositive patients with clinically NMOSD were analysed for the presence of MOG-IgG. Clinical characteristics of the AQP4-IgG, MOG-IgG seropositive and double seronegative NMOSD patients were compared. Twenty of the 61 AQP4-IgG seronegative patients tested MOG-IgG seropositive (33%). MOG-IgG seropositive patients were more frequently males in contrast to AQP4-IgG seropositive patients (55% vs. 15%, P < 0.01) and Caucasians (90% vs. 63%, P = 0.03). They more frequently presented with coincident optic neuritis and transverse myelitis (40% vs. 12%, P = 0.02) and had a monophasic disease course (70% vs. 29%, P < 0.01). AQP4-IgG seropositive patients were 2.4 times more likely to suffer from relapses compared with MOG-IgG seropositive patients (relative risk 2.4, 95% confidence interval 1.2-4.7). AQP4-IgG seropositive patients had higher Expanded Disability Status Scale levels at last follow-up (P < 0.01). Antibodies directed to MOG identify a subgroup of AQP4-IgG seronegative NMO patients with generally a favourable monophasic disease course. © 2015 EAN.

    A cross-sectional quantitative study of cutaneous bacterial and yeast flora at seven body sites in 99 human immunodeficiency virus-seropositive and 50 seronegative military personnel was performed. Statistically significant differences in carriage rates were only observed for Staphylococcus aureus on the foreheads of seropositive individuals. Seronegative individuals demonstrated staphylococcal carriage rates 1.3 to 2 times as great as those of historical controls (defined as healthy individu...

    Candidiasis is the most common opportunistic infection in human immunodeficiency virus (HIV) seropositive patients, starting from asymptomatic colonization to pathogenic forms and gradual colonization of non-albicans in patients with advanced immunosuppression leads to resistance for azole group of antifungal drugs with high rate of morbidity and mortality. To isolate the Candida species and determine of antifungal drug susceptibility against fluconazole, itraconazole, nystatin, amphotericin B, and clotrimazolein HIV seropositive and control individuals, with or without clinical oropharyngeal candidiasis (OPC). Includes samples from faucial region of 70 subjects with and without clinical candidiasis in HIV seropositive and controls were aseptically inoculated onto Sabaraud's Dextrose Agar media and yeasts were identified for the specific species by Corn Meal Agar, sugar fermentation and heat tolerance tests. Antifungal drug susceptibility of the isolated species was done against above-mentioned drugs by E-test and disc diffusion method. The commonly isolated species in HIV seropositive and controls were Candida albicans, Candida glabrata and Candida tropicalis Candida guilliermondii and Candida dubliniensis isolated only in HIV seropositive patients. Susceptibility against selected antifungal drugs was observed more in HIV-negative individuals whereas susceptible dose-dependent and resistance were predominant in HIV-positive patients. Resistance is the major problem in the therapy of OPC, especially in HIV seropositive patients due to aggressive and prolonged use of antifungal agents, therefore, our study emphasizes the need for antifungal drug susceptibility testing whenever antifungal treatment is desired, especially in HIV-infected subjects.

    Black and lesbian, gay, bisexual, or questioning (LGBQ) youth in the United States are disproportionately affected by HIV and other sexually transmitted diseases (STDs). Although self-efficacy is strongly, positively associated with safer sex behaviors, no studies have examined the validity of a safer sex self-efficacy scale used by many federally funded HIV/STD prevention programs. This study aims to test factor validity of the Sexual Self-Efficacy Scale by using confirmatory factor analysis (CFA) to determine if scale validity varies between heterosexual and LGBQ Black youth. The study uses cross-sectional data collected through baseline surveys with 226 Black youth (15 to 24 years) enrolled in community-based HIV-prevention programs. Participants use a 4-point Likert-type scale to report their confidence in performing 6 healthy sexual behaviors. CFAs are conducted on 2 factor structures of the scale. Using the best-fitting model, the scale is tested for measurement invariance between the 2 groups. A single-factor model with correlated errors of condom-specific items fits the sample well and, when tested with the heterosexual group, the model demonstrates good fit. However, when tested with the LGBQ group, the same model yields poor fit, indicating factorial noninvariance between the groups. The Sexual Self-Efficacy Scale does not perform equally well among Black heterosexual and LGBQ youth. Study findings suggest additional research is needed to inform development of measures for safer sex self-efficacy among Black LGBQ youth to ensure validity of conceptual understanding and to accurately assess effectiveness of HIV/STD prevention interventions among this population.

    Little research has explored parental engagement in schools in the context of adoptive parent families or same-sex parent families. The current cross-sectional study explored predictors of parents' self-reported school involvement, relationships with teachers, and school satisfaction, in a sample of 103 female same-sex, male same-sex, and heterosexual adoptive parent couples (196 parents) of kindergarten-age children. Parents who reported more contact by teachers about positive or neutral topics (e.g., their child's good grades) reported more involvement and greater satisfaction with schools, regardless of family type. Parents who reported more contact by teachers about negative topics (e.g., their child's behavior problems) reported better relationships with teachers but lower school satisfaction, regardless of family type. Regarding the broader school context, across all family types, parents who felt more accepted by other parents reported more involvement and better parent-teacher relationships; socializing with other parents was related to greater involvement. Regarding the adoption-specific variables, parents who perceived their children's schools as more culturally sensitive were more involved and satisfied with the school, regardless of family type. Perceived cultural sensitivity mattered more for heterosexual adoptive parents' relationships with their teachers than it did for same-sex adoptive parents. Finally, heterosexual adoptive parents who perceived high levels of adoption stigma in their children's schools were less involved than those who perceived low levels of stigma, whereas same-sex adoptive parents who perceived high levels of stigma were more involved than those who perceived low levels of stigma. Our findings have implications for school professionals, such as school psychologists, who work with diverse families. Copyright © 2014 Society for the Study of School Psychology.

  5. Fecundity of paternal and maternal non-parental female relatives of homosexual and heterosexual men.

    Directory of Open Access Journals (Sweden)

    Andrea Camperio Ciani

    Full Text Available A variety of social, developmental, biological and genetic factors influence sexual orientation in males. Thus, several hypotheses have attempted to explain the sustenance of genetic factors that influence male homosexuality, despite decreased fecundity within the homosexuals. Kin selection, the existence of maternal effects and two forms of balancing selection, sexually antagonistic selection and overdominance, have been proposed as compensatory mechanisms for reduced homosexual fecundity. Here, we suggest that the empirical support for kin selection and maternal effects cannot account for the low universal frequency and stability of the distribution of homosexuals. To identify the responsible compensatory mechanism, we analyzed fecundity in 2,100 European female relatives, i.e., aunts and grandmothers, of either homosexual or heterosexual probands who were matched in terms of age, culture and sampling strategy. Female relatives were chosen to avoid the sampling bias of the fraternal birth order effect, which occurs when indirectly sampling mothers though their homosexual sons. We observed that the maternal aunts and grandmothers of homosexual probands were significantly more fecund compared with the maternal aunts and maternal grandmothers of the heterosexual probands. No difference in fecundity was observed in the paternal female lines (grandmothers or aunts from either of the two proband groups. Moreover, due to the selective increase in maternal female fecundity, the total female fecundity was significantly higher in homosexual than heterosexual probands, thus compensating for the reduced fecundity of homosexuals. Altogether, these data support an X-linked multi-locus sexually antagonistic hypothesis rather than an autosomal multi-locus overdominance hypothesis.

    Two types of single-parent households and their effects on children ages 3-11 years were compared. One type comprised 50 homosexual mothers and their 56 children, and the other was a group of 40 heterosexual mothers and their 48 children. There were 30 daughters and 26 sons of homosexual mothers and 28 daughters and 20 sons of heterosexual mothers. The sexual identity and social relationships of the children were assessed in relation to the sexual orientation of the mothers. The samples consisted of families from rural and urban areas in 10 American states. All have lived without adult males (18 years or older) in the household for a minimum of 2 years (average 4). Families with heterosexual mothers were matched to families with homosexual mothers on age and race of mother; length of mother and child separation from father; educational level and income of mother; and number, age, and sex of children. Data are reported from childrens' tests designed to provide information on general intelligence, core-morphologic sexual identity, gender-role preferences, family and peer group relationships, and adjustment to the single-parent family. No significant differences were found between the two types of households for boys and few significant differences for girls. Concerns that being raised by a homosexual mother might produce sexual identity conflict and peer group stigmatization were not supported by the research findings. Data also revealed more similarities than differences in parenting experiences, marital history, and present living situations of the two groups of mothers. The postulated compromised parental fitness of lesbian mothers, commonly asserted in child custody cases, is not supported by these data.

    Nineteen young Thai women were purposively selected from networks of nongovernmental organizations involving children and youths in Bangkok. Our grounded theory findings indicated that these young women used the basic social process they called "waiting for the right time" in order to maintain heterosexual abstinence. Waiting for the right time involved one overarching condition, honoring parental love, and included three overlapping properties: learning rules, planning life path, and ways of preserving virginity. The findings provide information that may lead to the development of culturally competent interventions for middle-class Thai youths to remain healthy and avoid pregnancy.

    Sexuality research tends to ignore older populations, and little is known about older women's sexual health knowledge. To fill this research gap, 186 Canadian heterosexual women 50 years and older were surveyed about their knowledge regarding sexuality and HIV/AIDS. Respondents had moderate levels of overall knowledge of sexual health and aging, correctly answering, on average, 60% of the 35 questions. They had lower levels of HIV/AIDS knowledge, correctly answering just over 50% of the 25 questions. Results indicate the need for social awareness and education in this group regarding both general sexual health later in life and HIV/AIDS.

    BACKGROUND: Despite the existence of over 50 subtypes and circulating recombinant forms of HIV-1, subtype C dominates the heterosexual pandemic causing approximately 56% of all infections. OBJECTIVE: To evaluate whether viral genetic factors may contribute to the observed subtype-C predominance. ....... CONCLUSION: As CD4-CCR5-T cells are key targets for genital HIV infection and cervical selection can favor compact V1-V2 loops and 316T, which increase viral infectivity, we propose that these conserved subtype-C motifs may contribute to transmission and spread of this subtype....

    Does the prevalence of online education in fertility center websites differ for lesbian, gay, bisexual, transgender (LGBT) couples compared to online education for heterosexual couples? This review of fertility center websites showed that the majority of websites with patient education for heterosexual couples do not have similar materials for LGBT couples. In order to have biologically related children, LGBT individuals or couples utilize assisted reproductive technologies (ART). Fertility clinic websites provide online education to familiarize patients with the different ART procedures; however, no studies have examined the prevalence of educational information for LGBT couples compared to information for heterosexual couples utilizing ART. This website review evaluated Centers for Disease Control and Prevention (CDC)-reported fertility center websites. Websites were reviewed in 2014 using the latest 2011 CDC report, and reviewed again in 2015 with the latest 2013 CDC report. Patient education information was coded using categories determined after a sample review, and differences were analyzed with χ(2) tests, with P-values calculated with Fisher's exact test. In 2014, 31.1% (121) of 389 websites with information for heterosexual couples also contained information for LGBT couples. In 2015, the number of fertility centers with information for LGBT couples increased by 52.9% to 185 (P online information on fertility center websites may not directly reflect the quality of care LGBT individuals or couples receive in the clinic, and the effect of this absence of online information on the clinical experiences of LGBT patients is unknown. These findings add to the growing body of work showing disparities in the treatment of LGBT persons compared to the overall population. To overcome these discrepancies, healthcare providers should adapt their practice to include this growing and underserved patient population. Funding was provided by the Medical Student Summer

    Congenital (CI) and perinatal cytomegalovirus (CMV) infections (PI) can be linked to maternal CMV seropositivity, with fatal consequences in preterm newborns. GB genotyping has been used to analyze genotypic similarity in mothers and infants. The frequency of CMV infection in the context of maternal seropositivity and the viral gB genotypes as well as the genotypic similarity in mothers and preterm infants were investigated. Saliva samples and dry blood spots (DBS) were taken weekly from preterm newborns  from birth until the first month of life, and breast milk samples were taken from their mothers weekly during the first month of lactation. CMV IgG seroprevalence of the mothers and CI or PI in the infants were established. The gB status and genotypic similarities were established retrospectively in DBS and in the breast milk samples. In total, 387 neonates and 375 mothers were enrolled. The maternal CMV-positive IgG serology was 97.3% (365/375). Neonatal CMV was found in 5.1% (20/387) of newborns, and one infant presented with CMV-compatible symptoms. CI was 2.5% and PI in the first month after birth was 11.8%. GB2 was the most prevalent genotype and was also the genotype preferentially transmitted to newborns by mothers with mixed infections. CMV PI and CI in preterm infants from highly seropositive mothers was high, but the rate of symptomatic infection was low. The prevalent genotype was gB2, and this genotype was preferentially transmitted to newborns by mothers with mixed infections.

    Environmental, demographic, and entomologic variables were analyzed by logistic multiple regression analysis for their association with the likelihood of being seropositive for Trypanosoma cruzi in three highly infested rural villages of northwest Argentina. The prevalence of seropositivity for T. cruzi, as determined by the composite results of three serologic tests, was 34% among 338 persons in 1992. The strongest positive predictors of the adjusted odds of being infected were the household number of dogs, the density of T. cruzi-infected Triatoma infestans in bedroom areas, and each person's age. Dwellers from houses with roofs made completely or partly with a grass called simbol, or which used insecticides rudimentarily and nonsystematically, had a significantly lower odds of being seropositive for T. cruzi than residents from other types of dwellings. The adjusted odds of infection also increased with the number of T. cruzi-infected dogs or cats and the presence of chickens in bedroom areas. No significant effects on the adjusted odds of infection of a community-wide deltamethrin spraying carried out in one of the villages seven years before were detected. Socioeconomic indicators, such as domiciliary area, and numbers of corrals and livestock, were inversely related to being infected. Our study identified several manageable variables suitable for control actions, most of them not examined before in univariate or multivariate analyses. Environmental management based on low-cost housing with appropriate local materials and removal of domestic animals from domiciliary areas have a crucial role to play in the control of Chagas' disease in rural areas.

    There is a high prevalence of insomnia in HIV-seropositive patients. Insomnia is associated with poorer disease outcomes, cognitive impairment and HIV-associated dementia. However there is limited data characterizing the type of sleep disturbances, and the cause. Previous studies report conflicting results, and observed changes in the distribution of REM and SWS were hypothesized to result from co-morbid mood disorders, although this is not established. We carried out this study to determine if there are differences in polysomnographic (PSG) sleep data in age-, sex- and Axis I diagnoses- matched HIV-seropositive and HIV-seronegative patients. Eighteen HIV-seropositive insomniacs were matched to HIV-seronegative insomniacs based on age, sex and Axis I diagnoses. Participants spent 2 consecutive nights in a sleep lab recording of PSG data. Multivariate analysis revealed an overall significant match-by-variable interaction (p=0.0126). Follow-up analysis show that compared to HIV-seronegative insomnia controls, HIV-seropositive insomniacs have significantly longer SOL, 8% decreased sleep efficiency, and 8-10% decreased time spent in REM sleep (p'saccounting for differences in age, sex and psychiatric diagnoses, HIV-seropositive patients with insomnia have significantly worse sleep than HIV-seronegative patients with insomnia. Unlike what previous authors have proposed, our results do not support the view that comorbid psychiatric disorders like depression are responsible for the observed differences in PSG findings and the greater incidence of insomnia, in HIV-seropositive patients when compared with other groups of insomnia patients. This suggests the presence of other etiologies including neuronal damage, psychosocial stressors, or comorbid medical conditions. Further studies are needed to determine the extent to which these play a role in insomnia in the HIV-seropositive population. Copyright © 2012 International Federation of Clinical Neurophysiology.

    Full Text Available BACKGROUND The global impact of the converging dual epidemics of TB and HIV is one of the major public health challenges. The increasing rate of HIV infection in many countries has had an impact on TB epidemiology. As the prevalence of pulmonary tuberculosis is increasing among HIV seropositive patients with a wide range of immune status and clinical presentations, the present study was undertaken to assess the clinical and laboratory profile of sputum positive pulmonary tuberculosis among HIV seropositive and HIV seronegative patients. MATERIALS AND METHODS The present one year cross-sectional study was conducted in the Department of Medicine, KLES Dr. Prabhakar Kore Hospital and Medical Research Centre, Belgaum on 104 patients with sputum positive pulmonary tuberculosis patients during the period of January 2009 to December 2009. Routine investigations such as blood group, haemogram that is haemoglobin, total count, differential count, erythrocyte sedimentation rate, sputum smears for AFB and chest x-ray were done. RESULTS Seroprevalence of HIV among pulmonary tuberculosis patients was 23.08%. On examination anaemia, undernourishment, lymphadenopathy and the presence of opportunistic infections like oral candidiasis, herpes zoster stain and genital lesions were more predominant among HIV seropositives compared to HIV seronegatives. Mean Hb and TLC were significantly low among HIV seropositives compared to HIV seronegatives. Chest x-ray showed varied presentation. Upper zone infiltration, cavitation and fibrosis were more commonly involved among HIV seronegatives compared to HIV seropositives. CONCLUSION HIV seropositive PTB patients commonly present with fever, weight loss and loss of appetite, while cough with expectoration, haemoptysis, breathlessness were more common with HIV seronegative patients. Cavitation, fibrosis and fibrocavitary lesions were predominantly seen among HIV seronegatives, while infiltration and miliary mottling was

    Full Text Available To investigate an association between Helicobacter pylori seropositivity and HLA-B27-positive acute anterior uveitis (AAU in Korean patients.Retrospective analysis was performed with data from 106 patients previously diagnosed with AAU without clinical evidence of spondyloarthropathy. Serum immunoglobulin G antibodies to H. pylori were measured by enzyme-linked immunosorbent assay, and HLA typing was performed using polymerase chain reaction of DNA amplification. We included 72 non-uveitis patients and 35 age- and sex-matched healthy controls in the study.Of the 106 patients with AAU, 41 (38.7% were HLA-B27-positive, and 45 (42.5% were seropositive for H. pylori. Patients with HLA-B27-positive AAU had a significantly lower prevalence of H. pylori seropositivity compared to those with HLA-B27-negative AAU and healthy controls (24.4% vs. 53.8%, p = 0.003; 24.4% vs. 57.1%, p = 0.004, respectively. In the non-uveitis group, however, HLA-B27-positive patients exhibited similar H. pylori seropositivity prevalence to HLA-B27-negative patients and healthy controls (45.5% vs. 55.7%, p = 0.529; 45.5% vs. 57.1%, p = 0.497, respectively. In multivariate analysis, a low prevalence of H. pylori seropositivity was significantly associated with HLA-B27-positive AAU (odds ratio = 0.340, 95% confidence interval 0.135-0.855, p = 0.022.Our results suggest an inverse association between H. pylori seropositivity and HLA-B27-positive AAU. Further investigation of this association is needed, given the low prevalence of H. pylori seropositivity observed in patients with HLA-B27-positive AAU.

    The primary aim of this study was to investigate the relationship between gender role orientation and eating disorder attitudes and behaviors and body dissatisfaction in a sample of homosexuals, heterosexuals, and transsexuals. We screened 132 homosexuals, 178 heterosexuals (both male and female), and 15 MtF transsexuals by means of an ad hoc socio-demographic schedule; the Eating Disorders Inventory-2 and Symptom Checklist; the Body Uneasiness Test and the Bem Sex Role Inventory. Differences between homosexual, heterosexual, and transsexual participants emerged, but those data seem to be best explained by the constructs of femininity and masculinity than by the biological gender. The empirical evidence of a positive correlation between femininity and eating problems, and the negative correlation between masculinity and eating problems, is full of implications. Eating disorders appear to be diseases of femininity; masculinity seems to be a protective factor, independently by the biological gender.

    We investigated 109 (79.8% female; 76% White, and 83.5% Heterosexual) mental health trainees' explicit and implicit attitudes toward heterosexual, lesbian, and gay White couples adopting and raising Black children. To determine explicit attitudes, we used a vignette depicting a Black child ready for adoption and three types of equally qualified White families who were headed by a heterosexual couple, gay couple, or lesbian couple. The trainees were asked to indicate which type of family they preferred to adopt the child. To determine implicit attitudes, we used the computer programed latency-based multifactor implicit association test (IAT) protocol. The IAT data were collected from each participant individually. Explicit data showed that over 80% of the participants indicated no strong preference in terms of which type of family should adopted the child. However, IAT data showed that the trainees implicitly preferred lesbian couples. Overall, the degree of congruence between explicit and implicit was very low. Implications for training were discussed.

    The present study examined 100 lesbian and gay college students and 100 heterosexual students to determine whether group differences exist in frequency of a range of non-erotic cognitive distractions during sexual activity. Non-erotic cognitive distraction is a descriptive term for both self-evaluative cognitions related to physical performance and body image concerns, as well as additional cognitive distractions (e.g., contracting an STI or emotional concerns) during sexual activity. Participants were matched on gender (96 males and 104 females), age, and ethnicity, and completed questionnaires assessing frequency of non-erotic cognitive distractions during sexual activity, as well as measures of additional variables (trait and body image anxiety, attitudes toward sexual minorities, self-esteem, and religiosity). Results indicated that sexual minorities experienced significantly more cognitive distractions related to body image, physical performance, and STIs during sexual activity than heterosexuals. Regarding gender, men reported more distractions related to STIs than women. Interaction effects were observed between sexual orientation and gender for body image-, disease-, and external/emotional-based distractions. Implications of these findings are discussed.

    Full Text Available ABSTRACTHeterosexual men have been a forgotten group for HIV/AIDS interventions and research. Our goal was to identify the different elements that interfere in the prevention of HIV/AIDS among heterosexual men, covering both traditional methods of prevention (especially safe sex practices and testing and new strategies for prevention (pre- and post-sexual exposure prophylaxis, prevention treatment, and circumcision in this population. This exploratory article consists of a nonsystematic review of the literature. We discuss the invisibility of heterosexual men in policies, in programs, and in health services. The several interventions analyzed are still poorly monitored and evaluated, so there is a lack of consistent evidence regarding the impact of prevention strategies in this population. Different masculinities, including hegemonic conceptions of masculinity, must be the foundation for interventions targeting men. Men must not be seen merely as a "bridge" in the spread of the HIV/AIDS epidemic, but also as victims of gender patterns that make them vulnerable.

    The current study aimed to (1) offer a large-scale enumeration of college students' lifetime sexual behaviors and sexual behaviors at last event, and (2) apply a gender discrepancy lens to college students' sexual behaviors in order to examine potential gender differences in heterosexual college students' experiences. Nine-hundred and seventy college students between the ages of 18 and 27 from two large universities in the United States participated in the current study. Participants filled out a paper-pencil questionnaire during the last 30 min of class. Measures of lifetime sexual behaviors and engagement in behaviors at last sexual event were replicated from the National Survey of Sexual Health Behavior. Most college students engaged in some form of sexual behavior (manual, oral, vaginal-penile, anal). Men more frequently reported engaging in receptive sexual behaviors (e.g., receiving oral sex) where as women were more likely to engage in performative sexual behaviors (e.g., performing oral sex). At most recent sexual event, men were more likely than women to report being the sexual initiator. Findings highlight gender differences in sexual behavior and provide a foundation for social norms interventions. Holistic sexual health promotion for young adults includes acknowledging and discouraging sites of disparity in equity and pleasure. Therefore, college-level sexual health educators should pay attention to the potential pleasure gap between men and women in heterosexual encounters, and to see pleasure as an important part of sexual health that should be included in social norms campaigns.

    Although HIV prevention interventions for women are efficacious, long-term behavior change maintenance within power-imbalanced heterosexual relationships has been difficult. To explore the feasibility, content, and format of an HIV intervention for Latino couples, the authors conducted 13 focus groups with HIV/AIDS researchers, service providers, and heterosexual men and women in Puerto Rico, the Dominican Republic, and Mexico. Reasons that participants thought that men should be involved in prevention efforts included promotion of shared responsibility, creation of a safe environment for open conversation about sex, and increased sexual negotiation skills. Perceived barriers to men's involvement included cultural taboos, sexual conservatism associated with Catholicism and machismo, and power-imbalanced relationships. Participants stressed the need for recruitment of men within naturally occurring settings or by influential community leaders. Participants indicated that couples-level interventions would be successful if they used strong coed facilitators, included both unigender and mixed-gender discussion opportunities, and addressed personally meaningful topics. Implications of these findings are discussed.

    This study sought to identify factors associated with intention to change sexual practices among heterosexual Thai males diagnosed with sexually transmitted infections (STIs). STI clinic patients (n = 247) reported their sexual behaviors and condom use during the previous 3 months. STI and HIV knowledge, motivation to change sexual practices, and behavioral skills were assessed. Then, self-reported behavior change intention, including consistent condom use, reducing number of sexual partners, not using drugs and alcohol when having sex, and refusal of condomless sex, was examined. Consistent condom use in the past 3 months by Thai males diagnosed with STIs was low across all types of sexual partners (lover 13.8%, casual partner 14.9%, and sex worker 2.5%). Risk reduction self-efficacy (p behavior change intention. Significant predictors of behavior change intention were risk reduction self-efficacy (p behavior change intention variance. Intervention aimed at enhancing motivation and behavioral skills to adopt preventive behaviors should be developed to prevent recurrent STIs, including HIV infection, among heterosexual Thai males diagnosed with STIs.

    The meta-analysis reported here examined interventions informed by the theory of planned behavior (TPB) or theory of reasoned action (TRA) aimed at reducing heterosexual risk behaviors (prevention of STDs and unwanted pregnancy). Studies were eligible for inclusion if they were either randomized control trials or quasi-experimental studies that compared the TPB-based intervention against a control group. Search strategy consisted of articles identified in previous reviews, keyword search through search engines, examination of key journals, and contacting key experts. Forty-seven intervention studies were included in the meta-analysis. Random effects models revealed that pooled effect sizes for TPB-based interventions had small but significant effects on behavior and other secondary outcomes (i.e., knowledge, attitudes, normative beliefs, perceived behavioral control, and intentions). Significant heterogeneity found between effect sizes was explored using metaregression. Larger effects were found for interventions that provided opportunities for social comparison. The TPB provides a valuable framework for designing interventions to change heterosexual risk behaviors. However, effect sizes varied quite substantially between studies, and further research is needed to explore the reasons why.

    Oxytocin is an evolutionarily highly preserved neuropeptide that contributes to the regulation of social interactions including the processing of facial stimuli. We hypothesized that its improving effect on social approach behavior depends on perceived sexual features and, consequently, on sexual orientation. In 19 homosexual and 18 heterosexual healthy young men, we investigated the acute effect of intranasal oxytocin (24IU) and placebo, respectively, on the processing of social stimuli as assessed by ratings of trustworthiness, attractiveness and approachability for male and female faces. Faces were each presented with a neutral, a happy, and an angry expression, respectively. In heterosexual subjects, the effect of oxytocin administration was restricted to a decrease in ratings of trustworthiness for angry female faces (poxytocin administration robustly increased ratings of attractiveness and approachability for male faces regardless of the facial expression (all p ≤ 0.05), as well as ratings of approachability for happy female faces (poxytocin's enhancing impact on social approach tendencies, suggesting that differences in sexual orientation imply differential oxytocinergic signaling.

    This qualitative analysis elucidates the potential elements of the intervention that may be effective in terms of a) increasing knowledge about HIV/ AIDS in the members of this population; b) increasing the use of male condoms and the practice of mutual masturbation; and c) changing opinions toward male condom use and mutual masturbation. Five heterosexual HIV-discordant couples participated in the adapted intervention, which consisted of four three-hour-long sessions. One month after the intervention, we conducted a qualitative semi-structured interview with every participant to evaluate issues related to the process and content of the activities comprising the intervention, the impact of the intervention, logistics, and recruitment and retention as well as to make a more general evaluation. The information was submitted to qualitative content analysis. After the intervention, participants reported having better attitudes regarding safer sex, particularly in terms of condom use. A reason given by the participants to feel more positive toward condom use and mutual masturbation was that these practices could prevent the infection of the HIV-negative partner. This study provides important evidence of an intervention that promises to be efficacious in preventing some high-risk sexual behaviors among Latino HIV-discordant heterosexual couples. The evidence presented seems to suggest that an intervention that includes basic relevant information about HIV/AIDS, that explains the benefits of condom use and other safer sex options, and that provides effective negotiation and communication strategies could significantly reduce HIV transmission among these couples.

    We conducted molecular analyses to confirm four clustering HIV-1 infections (Patient A, B, C & D) in Guangzhou, China. These cases were identified by epidemiological investigation and suspected to acquire the infection through a common heterosexual transmission chain. Env C2V3V4 region, gag p17/p24 junction and partial pol gene of HIV-1 genome from serum specimens of these infected cases were amplified by reverse transcription polymerase chain reaction (RT-PCR) and nucleotide sequenced. Phylogenetic analyses indicated that their viral nucleotide sequences were significantly clustered together (bootstrap value is 99%, 98% and 100% in env, gag and pol tree respectively). Evolutionary distance analysis indicated that their genetic diversities of env, gag and pol genes were significantly lower than non-clustered controls, as measured by unpaired t-test (env gene comparison: p Epidemiological results and molecular analyses consistently illustrated these four cases represented a transmission chain which dispersed in the locality through heterosexual contact involving commercial sex worker.

    Drawing upon quantitative and qualitative data we explore perspectives on and experiences of sexual lifestyles and relationships among more than 1,750 adolescents aged 17-20 years who reside in urban Chiang Mai, Thailand. We focus on respondents’ representations and understandings of their sexual/gender identities derived mainly from in-depth interviews and focus group discussions, supplemented with observations and field notes. Our results show that while many young Thais described themselves as heterosexual males or females others described themselves as gay, kathoey, tom, dii, bisexual or something else. Some were still questioning their own identities. The terms gay, kathoey, tom and dii are commonly used by these Thais to describe a range of sexual/gender identities relating to persons who are sexually or romantically attracted to the same biological sex. We use case studies to illustrate the distinctive characterizations, sexual lifestyles and relationships of each of these identities. We conclude that the sexual lifestyles encountered among Northern Thai non-heterosexual adolescents could lead to negative health consequences and indicated a need for improved relationship education, counselling and sensitive sexual health services.

    This paper describes perceptions of the societal acceptability and acceptability among peers of different types of premarital heterosexual relationships in Iran. Sources of variation in subjective norms are assessed. Results derive from a survey conducted in 2005 of a representative sample of 1743 female college students from four multidisciplinary universities in Tehran using two-stage random cluster sampling. An anonymous pilot-tested questionnaire was used. Respondents displayed remarkable heterogeneity and ambiguity concerning the social acceptability of premarital heterosexual friendship, dating and physical contact, but expressed greater certainty about the unacceptability of premarital sex. The majority (77.5%) reported that premarital sex was socially prohibited, while about one third (33.1%) were unsure about the social acceptability of having a boyfriend and dating before marriage. Peer norms were perceived to be more liberal but, nevertheless, very few peers were thought to be in favour of premarital intercourse. Older students, those with educated fathers and those studying in a mixed-sex university perceived norms to be more liberal than their counterparts. Access to satellite television, a major source of exposure to new information and values about sexuality, was a major predictor of liberal peer norms. It appears that a significant proportion of young people in Tehran have broken with tradition with regard to premarital social interaction and romantic friendships, but the majority still conforms to traditional cultural and religious values regarding abstinence before marriage.

    Condoms are less likely to be used in primary relationships than in other relationship types. An understanding of what women and men expect when entering into these relationships, as well as how they make decisions about condom use and other prevention behaviors, is essential to efforts to curb the spread of HIV. Qualitative in-depth interviews were conducted with 25 high-risk heterosexual couples, including HIV-serodiscordant couples, participating in a trial of the female condom in Hartford in 2004-2007. Data were coded and analyzed in an iterative inductive and deductive process. Participants described nonuse of condoms as a strategy to fi nd and maintain a primary relationship, establish trust and increase intimacy. Many had unprotected intercourse while recognizing their risk of HIV and other STDs, placing their love for their partner and other emotional needs over concerns about their health. Several couples reduced their STD risk by practicing negotiated safety (i.e., using condoms until their serostatus had been determined) or similar strategies, including sharing sexual or drug use history, disclosing HIV test results and using condoms until they decided that their relationship would be monogamous. HIV prevention approaches must recognize the importance of love and the needs that primary relationships satisfy if they are to be considered relevant by those at greatest risk. Negotiated safety and similar strategies may be an important risk reduction tool for heterosexuals, particularly those in HIV-affected relationships, but their potential effectiveness may vary.

    Relationships in which power is equally distributed are consistently associated with greater quality (e.g., deeper intimacy, less turmoil, more pleasure), but it can be difficult to strike such a balance. Furthermore, dominant gender scripts and norms are complexly intertwined with power in heterosexual relationships. We studied the joint implications of power and gender for relationship quality using 114 U.S. emerging adults' quantitative and qualitative assessments of 395 heterosexual relationships. Linear mixed method analyses indicated that participants found relationships in which they shared power or were dominant to be more intimate and stable than those in which they felt subordinate, but we found no link between power and pleasure. Gender acted as a moderator such that women rated relationships in which they felt subordinate as less intimate and more tumultuous than those in which they felt dominant, whereas men's ratings did not vary by whether they felt subordinate or dominant. Qualitative data also showed power imbalances to be more problematic for women: Of the 17 relationships involving an abusive or controlling partner, 15 were reported by women. We conclude that while both young men and young women may feel subordinate in relationships, the consequences thereof are more detrimental for young women.

    In light of evidence that racial discrimination and posttraumatic stress symptoms (PTSS) are neither rare nor extraordinary for many Black urban men, we examined the relationship between everyday racial discrimination and sexual HIV risk behaviors in a predominantly low-income sample of 526 urban Black heterosexually identified men; 64% of whom were unemployed and 55% of whom reported a history of incarceration. We tested the hypothesis that PTSS would mediate the relationship between everyday racial discrimination and sexual risk. Participants in the predominantly low-income urban sample ranged in age from 18 to 45 (M = 28.80, SD = 7.57). Three multiple regression models were used to test the study's mediational model. As hypothesized, PTSS mediated the relationship between everyday racial discrimination and sexual risk behaviors. Most participants (97%) reported experiences with everyday racial discrimination. Results empirically support the notion of racial discrimination-based traumatic stress as a pathway to Black heterosexual men's increased sexual risk behaviors. Results also highlighted key demographic differences with older men reporting fewer PTSS and sexual risk behaviors compared with younger men. Incarceration was related to both PTSS and sexual risk, underscoring the role that incarceration may play in Black heterosexual men's adverse health outcomes. Our study highlights the need for more qualitative and quantitative research to understand the nature of PTSS in Black heterosexual men and mechanisms such as substance use that may link traumatic experiences and sexual risk. Future research could also assess experiences with childhood sexual abuse, violence, and incarceration to gain a more in-depth understanding of the sources of traumatic stress in Black heterosexual men's lives. We advocate for the development of community-based individual and structural-level interventions to help Black heterosexual men in urban areas develop effective strategies to

    In the first phase of the survey, 2031 university students aged 18-40 from among 7 universities (both public and private in Tehran were selected using two stage stratified cluster sampling method. Data collection was completed between January 2010 and May 2011 using an anonymous self-administer valid and reliable questionnaire. The mean age of respondents was 22.5, 12% were married with a mean age at marriage of 27(SD=6.32. The influence of premarital heterosexual relationships on marriage age was assessed among married and on desire to marry among single students. The results show that after control of gender, economic and cultural situation of the family, the experience of progressive (sexual relationship between opposite sex is one of the determinant factors of marriage age among university students. Reporting experience of progressive premarital heterosexual relationships and intimacy are associated with about two years delay in marriage (b-coefficient=1.7, P<0/05 Moreover, There is a gender difference in the relations between premarital heterosexual relationships and desire for marriage. So as, both heterosexual friendships and intimacy was significantly linked with greater desire for marriage among females, while among men, only progressive intimacy was inversely linked with desire for marriage. Men with greater experiences showed lower desire for marriage, while premarital heterosexual friendship was not associated with marital desire and propensity.  The changes in trends of premarital heterosexual relationships among young people and recent types of partnerships needs to be considered more than before in evolution of marriage and the family in Iran and also differing implications of such relationships between men and women needs greater consideration.

    More and more lesbian couples are planning parenthood through donor insemination and IVF and the number of planned lesbian families is growing in Sweden and other western countries. Research has shown that lesbian couples report as much overall satisfaction in their relationships as do heterosexual couples. However, although parenthood is highly desired, many parents are unaware of the demands of parenthood and the strain on their relationship that the arrival of the baby might bring. The aim of this study was to compare lesbian and heterosexual couples' perceptions of relationship satisfaction at a three-year follow up after assisted reproduction. The present study is a part of the Swedish study on gamete donation, a prospective longitudinal cohort study. The present study constitutes a three-year follow up assessment of lesbian and heterosexual couples after assisted reproduction. Participants requesting assisted reproduction at all fertility clinics performing gamete donation in Sweden, were recruited consecutively during 2005-2008. A total of 114 lesbian women (57 treated women and 57 partners) and 126 heterosexual women and men (63 women and 63 men) participated. Participants responded to the ENRICH inventory at two time points during 2005-2011; at the commencement of treatment (time point 1) and about three years after treatment termination (time point 3). To evaluate the bivariate relationships between the groups (heterosexual and lesbian) and socio-demographic factors Pearson's Chi- square test was used. Kolmogorov-Smirnov test was used for testing of normality, Mann-Whitney U- test to examine differences in ENRICH between the groups and paired samples t-test to examine scores over time. Lesbian couples reported higher relationship satisfaction than heterosexual couples, however the heterosexual couples satisfaction with relationship quality was not low. Both lesbian and heterosexual couples would be classified accordingly to ENRICH-typology as vitalized or

    Advances in production and distribution of sexually explicit media (SEM) online have resulted in widespread use among men. Limited research has compared contexts of use and behaviors viewed in Internet SEM by sexual identity. The current study examined differences in recent SEM use (past 6 months) by sexual identity among an ethnically diverse sample of 821 men who completed an online survey in 2015. Both gay and bisexual men reported significantly more frequent use of Internet SEM compared to heterosexual men. Although most participants reported viewing SEM at home (on a computer, tablet, or smartphone), significantly more gay men reported SEM use at a sex party or commercial sex venue than either heterosexual or bisexual men. Sexual identity predicted viewing of high-risk and protective behaviors in separate logistic regression models. Specifically, compared to heterosexual men, gay and bisexual men had increased odds of viewing condomless anal sex (gay OR 5.20, 95 % CI 3.35-8.09; bisexual OR 3.99, 95 % CI 2.24-7.10) and anal sex with a condom (gay OR 3.93, 95 % CI 2.64-5.83; bisexual OR 4.59, 95 % CI 2.78-7.57). Compared to gay men, heterosexual and bisexual men had increased odds of viewing condomless vaginal sex (heterosexual OR 27.08, 95 % CI 15.25-48.07; bisexual OR 5.59, 95 % CI 3.81-8.21) and vaginal sex with a condom (heterosexual OR 7.90, 95 % CI 5.19-12.03; bisexual OR 4.97, 95 % CI 3.32-7.44). There was also evidence of identity discrepant SEM viewing as 20.7 % of heterosexual-identified men reported viewing male same-sex behavior and 55.0 % of gay-identified men reported viewing heterosexual behavior. Findings suggest the importance of assessing SEM use across media types and contexts and have implications for research to address the potential influence of SEM on sexual behavior (e.g., investigate associations between viewing condomless vaginal sex and engaging in high-risk encounters with female partners).

    Full Text Available Candida is a common opportunistic pathogen during the course of human immunodeficiency virus (HIV disease progression. Changes in the clinical severity of candidiasis and the Candida species prevalence profile may be a reflection of immunological changes in HIV positive patients. The aim of this study was to document the changing pattern of Candida species prevalence profile in HIV seropositive patients from a tertiary care hospital in North India. One hundred and twenty HIV seropositive subjects were recruited for Candida microbial screening. Clinical specimens including blood, oral swabs, expectorated or induced sputum/bronchoalveolar lavage specimens, and urine were collected depending on the patient’s symptoms. A total of 128 Candida isolates were obtained from 88 cases and 7 different Candida species were identified. C. albicans (50% was the most common species isolated followed by C. glabrata (17% and C. dubliniensis (12.5%. Other species isolated were C. parapsilosis (7.8%, C. krusei, C. tropicalis (4.6% each, and C. kefyr (3%. Strong clinical suspicion along with optimal sampling of an accurate diagnosis of Candida species involved would go a long way in decreasing the morbidity associated with non-albicans Candida species.

    Human Immunodeficiency Virus and Hepatitis B virus are blood borne pathogens that can be transmitted through blood transfusion and could pose a huge problem in areas where mechanisms of ensuring blood safety are suspect. This study became necessary in a population where most of the blood for transfusion is from commercial blood donors. A total of 130 donors comprising 120 commercial donors and 10 voluntary donors were tested for antibodies to human immunodeficiency virus and hepatitis B surface antigen in Benin city using Immunocomb HIV - 1 and 2 Biospot kit and Quimica Clinica Aplicada direct latex agglutination method respectively. Thirteen (10%) samples were HIV seropositive and 7(5.8%) were HBsAg positive. The age bracket 18 - 25years had the highest numbers of donors and also had the highest number of HBsAg positive cases (7.8%) while the age group 29 - 38years had highest number of HIV seropositive cases. High prevalence of HIV antibodies and Hepatitis B surface antigen was found among commercial blood donors. Appropriate and compulsory screening of blood donors using sensitive methods, must be ensured to prevent post transfusion hepatitis and HIV.

    To study the various clinical presentations of herpes zoster and to find out the proportion of HIV positivity in these patients. A time bound study was conducted from November 2004 to October 2005. All clinically diagnosed cases of herpes zoster were tested for HIV infection with ELISA and confirmed by Tridot and Coomb AID. Total numbers of 90 zoster cases were recorded. Mean duration of pre herpetic neuralgia was 2.134 (standard deviation=1.424, F=8.951, Psacral (6.66%) nerves. A substantial proportion, 34 (37.77%) out of 90 cases, were found to be HIV positive. Of these, 64.7 percent of the HIV seropositive herpes zoster patients belonged to the age group of 21-40 years. Out of 39 who had a risk of exposure to STDs and whose ages were less than 50 years, 31 (79.48%) tested positive for HIV infection. The occurrence of zoster in the young age group in patients who report a history of risk factors for HIV, may need testing. Herpes zoster serves as a clinical indicator of HIV seropositivity and one of the earliest manifestations.

  11. [African mobilization against AIDS. After the Kinshasa Conference].

    Poissonnier, A

    The AIDS epidemic in Africa has become too massive to ignore. A sign of increasing awareness of the AIDS threat was the attendance of some 1200 participants at the 5th international conference on AIDS in Africa held in Kinshasa, Zaire, in October 1990. An African society to combat AIDS has been formed and is based in Nairobi. The new association will be responsible for organization of coming conferences to be held in Africa rather than in Europe. Sub-Saharan Africa contains less than 10% of the world's population but 2/3 of adult AIDS cases and almost 90% of maternal and child cases. The epidemic is even more worrisome because it has brought with it a recrudescence of other illnesses such as tuberculosis. The World Health Organization estimates that 5 million Africans were seropositive in 1990 vs 2.5 million in 1987. Predictions are necessary and allow planning to begin for the care of the 10 million orphans who will be found in Africa by the year 2000 and for other serious problems created by the disease. But the situation is already very dire. There has been a certain stabilization in the number of cases in countries such as that Congo, Zaire, or the Central African Republic. As yet the stabilization cannot be explained. The pessimistic view is that the pause results from a purely statistical phenomenon due to increased mortality. The optimistic view is that sexual behavior is responding to health information campaigns. Although the experts had expected the AIDS epidemic to be limited to urban zones in Africa, rural rates already approach urban rates in several countries such as the Ivory Coast, Tanzania, Uganda, and Rwanda. Mother-infant contamination is the greatest worry of health officials. The number of infants infected during pregnancy or birth is expected to double to 1 million by 1992 and reach nearly 10 million in 2000. Some 20-25 million Africans will be seropositive by 2000. A cure for AIDS is unlikely in the near future. Products delaying the onset of

    Emotional intimacy cuts across contexts as diverse as sexual motivation and satisfaction, psychological and physical health, and relational well-being. Although the experience of intimacy and its effects on sex life may be gender and sexual orientation-specific, the role of intimacy in personal and sexual relationships has been studied mostly among heterosexual individuals and couples. Using the minority stress framework (Meyer, 2003) to address this gap in knowledge, the present study comparatively explored levels and predictors/correlates of emotional intimacy, and its association with sexual satisfaction among coupled heterosexual and gay/bisexual men sampled online in a predominantly homonegative country (Croatia). Heterosexual participants (n = 860; M age = 36.4, SD = 9.09) were recruited in 2011 and gay/bisexual participants (n = 250; M age = 29.4, SD = 7.13) in 2013. Controlling for age and relationship duration, gay/bisexual men reported higher levels of emotional intimacy than heterosexual men. Suggesting that the role of emotional intimacy in sexual satisfaction is not sexual orientation-specific, the strength of the association between these two constructs was similar in both samples. However, internalized homonegativity, which was negatively associated with emotional intimacy in this study, remains a challenge to creating and maintaining intimacy in male same-sex relationships.

    Research on Black sexual health often fails to represent the heterogeneity of Black ethnic groups. For people of Caribbean descent in the USA, ethnicity is a salient cultural factor that influences definitions and experiences of sexual health. Most research on people of Caribbean descent focuses on the relatively high rate of STIs, but sexual health is defined more broadly than STI prevalence. Psychological and emotional indicators and the voice of participants are important to consider when exploring the sexual health of a minority culture. The purpose of this study was to qualitatively explore how heterosexual Black men of Caribbean descent define and understand sexual health for themselves. Eleven men who self-identified as Black, Caribbean and heterosexual participated in three focus groups and were asked to define sexual health, critique behaviours expertly identified as healthy and address what encourages and discourages sexual health in their lives. Findings point to six dimensions of sexual health for heterosexual Black men of Caribbean descent. These include: heterosexually privileged, protective, contextual, interpersonal, cultural and pleasurable dimensions. There were some notable departures from current expert definitions of sexual health. Recommendations for further theory development are provided.

    The present study provides a comparative analysis of sexual-minority and heterosexual emerging adult women's experiences seeking support for sexual issues from parents and friends. Participants included 229 college women (88 sexual-minority women; 141 heterosexual women), ranging from 18 to 25 years of age, who provided written responses to an inquiry about a time they went to friends and parents for support for a issue related to their sexuality. Responses indicated that the majority of participants had sought support from either a parent or a friend and that mothers and female friends were more likely involved than fathers or male friends, respectively. Sexual issues that participants reported discussing with parents and friends were inductively grouped into five categories: dating and romantic relationships, sexual behavior, sexual health, identity negotiation, and discrimination and violence. Issues that were discussed differed based on sexual orientation identity and the source of support (parent or friend); they did not differ by age. Participants generally perceived parents and friends' responses as helpful, though sexual-minority participants perceived both parents and friends' responses as less helpful than did heterosexual participants. Overall, results suggest both similarities and differences between sexual-minority and heterosexual young women's experiences seeking support for sexual issues from parents and friends.

    The traditional stereotype of the typical woman has been described as "nice, but incompetent." However, such general gender stereotypes are applied to individual targets only under certain conditions: They are used to "fill in the blanks" (Heilman, 2012) if little personal information is provided about a target. "Typical lesbians" are regarded to have more typically masculine (agentic) characteristics such as task competence than the typical woman does. We thus hypothesized that if a woman displays behavior coinciding with the stereotype of the typical woman, it is more readily interpreted as stereotypically female if performed by a heterosexual woman than by a lesbian. Participants (N = 296) read a hypothetical job interview in which we manipulated the target's sexual orientation (between subjects). Findings demonstrated that a lesbian was judged as more competent than a heterosexual woman in the presence of behavior that may be interpreted as gender-stereotypical (Experiments 1 and 2). This difference in competence judgments was not found in the absence of gender-stereotypical behavior (Experiment 1). Judging the heterosexual woman as low in masculinity was related to a judgment of lower competence (Experiment 2). Our findings demonstrate that there are conditions under which lesbians, a group often stereotyped negatively, are less susceptible to invoking negative female stereotypes than heterosexual women are.

    The traditional African society places an invaluable premium on procreation and, in some communities, a woman's place in her matrimony is only confirmed on positive reproductive outcome. Infertility is rife in Nigeria, and HIV/acquired immunodeficiency syndrome (AIDS) infection is a global pandemic, which has led to a drop in life expectancy across the world. In Nigeria, a number of cultural norms relating to gender roles and power dynamics constitute a serious barrier to issues of sexuality and infertility. Couples are concerned about their infertility diagnostic test being disclosed to each other, especially before marriage. This concern is understandable, especially in an environment that lacks the modern concepts and attitude toward sexual matters. This is complicated by the advent of HIV/AIDS infection and the societal mind-set that look at seropostive individuals as transgressors. At present, sexual and reproductive health rights are currently not in place because ethical issues are not given prominence by many physicians in Nigeria. A case of an infertile and seropostive discordant couple, which raised a lot of medical and ethical concerns, is presented here to awaken the consciousness of Nigerian physicians and stimulate discussions on the ethical matters such as this in clinical practice.

    African American women are disproportionately affected by HIV/AIDS. Concurrent sexual partnerships may contribute to racial disparities in HIV infection. Little is known about attitudes and practices related to concurrency among African American women, or the social, structural and behavioural factors influencing concurrency. We recruited 19 heterosexual African American women engaging in concurrent sexual partnerships from a public clinic in Philadelphia in 2009. We conducted interviews exploring social norms, attitudes and practices about concurrency, and the structural, social and behavioural factors influencing concurrent sexual partnerships, guided by grounded theory. Seventeen women reported one main and one or more non-main partners; two reported no main partners. Many women used condoms more frequently with non-main than main partners, noting they trust main partners more than non-main partners. Social factors included social normalisation of concurrency, inability to negotiate partners' concurrent partnerships, being unmarried, and not trusting partners. Lack of trust was the most commonly cited reason that women engaged in concurrent partnerships. Structural factors included economic dependence on partners, partners' dependence on women for economic support and incarceration that interrupted partnerships. Behavioural factors included alcohol and cocaine use. Social, structural and behavioural factors strongly influenced these African American women's concurrent sexual partnerships. Many HIV interventions disseminated by the CDC focus largely on behavioural factors and may fail to address the social and structural factors influencing African American women's sexual networks. Novel HIV prevention interventions that address the social determinants of African American women's HIV risks are urgently needed.

    Full Text Available BACKGROUND: Contacts of leprosy patients are at increased risk of developing leprosy and need to be targeted for early diagnosis. Seropositivity to the phenolic glycolipid I (PGL-I antigen of Mycobacterium leprae has been used to identify contacts who have an increased risk of developing leprosy. In the present study, we studied the effect of seropositivity in patient contacts, on the risk of developing leprosy, stratified by Bacille Calmette Guerin (BCG vaccination after index case diagnosis. METHODOLOGY/PRINCIPAL FINDINGS: Leprosy contacts were examined as part of the surveillance programme of the Oswaldo Cruz Institute Leprosy Outpatient Clinic in Rio de Janeiro. Demographic, social, epidemiological and clinical data were collected. The presence of IgM antibodies to PGL-I in sera and BCG vaccination status at the time of index case diagnosis were evaluated in 2,135 contacts. During follow-up, 60 (2.8%; 60/2,135 leprosy cases were diagnosed: 41 among the 1,793 PGL-I-negative contacts and 19 among the 342 PGL-I-positive contacts. Among PGL-I-positive contacts, BCG vaccination after index case diagnosis increased the adjusted rate of developing clinical manifestations of leprosy (Adjusted Rate Ratio (aRR = 4.1; 95% CI: 1.8-8.2 compared with the PGL-I-positive unvaccinated contacts (aRR = 3.2; 95% CI: 1.2-8.1. The incidence density was highest during the first year of follow-up for the PGL-I-positive vaccinated contacts. However, all of those contacts developed PB leprosy, whereas most MB cases (4/6 occurred in PGL-I-positive unvaccinated contacts. CONCLUSION: Contact examination combined with PGL-I testing and BCG vaccination remain important strategies for leprosy control. The finding that rates of leprosy cases were highest among seropositive contacts justifies targeting this specific group for close monitoring. Furthermore, it is recommended that PGL-I-positive contacts and contacts with a high familial bacteriological index

    Full Text Available A 55-year-old heterosexual male presented to the emergency department with a symptomatology consistent with urethritis and Fournier’s gangrene. Urethral swab and operative tissue cultures were positive for coagulase-negative Staphylococcus and an intracellular Gram-negative diplococcus. The latter was initially thought to be Neisseria gonorrhea; however, DNA sequencing technique confirmed it to be Neisseria meningitidis. The patient required three separate surgical debridements to control widespread necrotizing infection. Following documentation of sterile wound healing with appropriate antibiotics, four reconstructive surgeries were necessary to manage the resultant wound defects. To our knowledge, Neisseria meningitidis as a causative organism in Fournier’s gangrene has not been reported in the literature.

    2016-01-01

    This paper critiques the approach to the elimination of gender inequality as an HIV prevention strategy in the just ended era of the Millennium Development Goals, with the aim of contributing to the formulation of policy guidelines for sub-Saharan Africa in the Sustainable Development Goals. The aim is to underscore the mutual responsibility of women and men in achieving a sustainable HIV response and ending the epidemic. While taking into account the real vulnerability of women, prevention programmes can reflect gender dynamics more accurately so that attention is given to the role of both sexes in propagating - or stemming - a predominantly heterosexual HIV epidemic. More emphasis could be given to the harm caused to both men and women by certain norms related to masculinity and sexuality, and the subsequent need for combined efforts in reducing intimate partner violence and concurrency. The empowerment and engagement of both women and men as agents of change would need to be dealt with more creatively.

  7. Three Co-Existing Sexually Transmitted Diseases in a Heterosexual Male Youth: A Case Report

    Theetat M. Surawan

    2016-03-01

    Full Text Available Most sexually transmitted diseases (STDs are asymptomatic, leading to widespread underdiagnoses estimated at 50% or higher. The presence of one STD significantly indicates an individual’s sexual health risk since an STD contributes to the transmission and acquisition of other STDs, including human immunodeficiency virus (HIV infection. Multiple co-existing STDs, thus, further increase the susceptibility of acquiring and transmitting HIV by twofold or more. Therefore, the comprehensive STD prevention strategies play a major role in reducing the transmission of HIV infection. We report an interesting case of a heterosexual male youth who presented at dermatology clinic with three concurrent sexually transmitted diseases: gonococcal urethritis, genital wart, and late latent syphilis. The case demonstrated significant issues for appropriate approaches and management of multiple co-existing STDs. Also, it reinforced the necessity for STD counselling for the patient, his partners, and family.

    2017-01-01

    For individuals in exclusive romantic relationships, the dynamics of sexual experimentation are nuanced. Extradyadic behavior outside of a relationship may be perceived as cheating or infidelity, with much of those perceptions driven by the biological sex of the perceiver. This study significantly reframes seminal research on perceptions of cheating with third-party friends by Kruger et al. (2013), to further nuance an evolutionary threat-based model. In doing so, this furthers our understanding of the associated perceptions of individuals in heterosexual relationships when confronted by partners' cheating with their same-sex cross-orientation friends. Results indicate that perceptions of same-sex infidelity vary widely depending on the nature of the behaviors, with decreasing attribution given to sexual and erotic behaviors, close relational behaviors, and casual social interaction behaviors, respectively. Implications are discussed for a variety of sexual communities, as well as the impact of gender and relational status on perceptions of infidelity.

    In a study of Haitians in Miami and New York, Creole-speaking interviewers questioned 55 patients with acquired immunodeficiency syndrome (AIDS) (45 men and ten women) and 242 control-persons (164 men and 78 women). One male patient was homosexual, and one female patient had received blood within five years. No one admitted to intravenous drug use, hemophilia, or sexual contact with AIDS patients. Male AIDS patients were significantly more likely than control-men to have entered the US after 1977 and to have had gonorrhea, syphilis, and sexual contact with female prostitutes. Female AIDS patients were more likely to have voodoo-priest friends and to have been offered money for sex. Acquired immunodeficiency syndrome was probably contracted through sexual contact with infected heterosexuals

    Full Text Available Some authors state that one of the functions of explicit homophobia is defensive, and that it has roots in latent attraction towards same sex. Large body of evidence suggests that implicit techniques enable assessment of those cognitions hidden from conscious awareness. Sample of 277 heterosexuals completed several implicit (Implicit Association Test-IAT and Affective Priming-AP and explicit measures of attitude (Test of homophobia and Connotative differential. Multi-group SEM analysis was done to investigate cross-sample stability of the model postulating influence of IAT and AP factors on latent explicit factor. Analyses suggest that both in males and females IAT latent factor predicts negative explicit attitude. Results revealed that explicit homophobia is related to implicit, negative attitude toward homosexuals and not to implicit attraction towards same sex.

    In heterosexual individuals, attention is automatically captured by physically attractive members of the opposite sex. Although helpful for selecting new mates, attention to attractive relationship alternatives can threaten satisfaction with and commitment to an existing romantic relationship. The current study tested the hypothesis that although a mating prime would increase selective attention to attractive opposite-sex targets (relative to less attractive targets) among single participants, this effect would be reduced among people already committed to a long-term romantic partner. Consistent with hypotheses, whereas single participants responded to a mating prime with greater attentional adhesion to physically attractive opposite-sex targets (relative to less attractive targets), participants in a committed romantic relationship showed no such effect. These findings extend previous research suggesting the presence of relationship maintenance mechanisms that operate at early stages of social cognition.

    2009-05-01

    Self-efficacy has been defined as one of the factors that may facilitate or impede safer sex. Studies reveal that peoples in steady relationships practice safer sex less often that those in casual relationships. We conducted a study with 447 sexually active heterosexual adults. A self-administered questionnaire was designed to study the sexual behavior, the male condom use and the practice of mutual masturbation, and the self-efficacy toward these practices. Results show that most men are sexually active and that there is a low frequency of male condom use and the practice of mutual masturbation as safer sex. The majority of those who use the male condom are engage in casual relationships. However, participants have high levels of self-efficacy toward these practices. Although self-efficacy is one of the factors that influence in deciding to practice safer sex, it is not sufficient to reach this goal.

  13. Sexual economics: sex as female resource for social exchange in heterosexual interactions.

    Baumeister, Roy F; Vohs, Kathleen D

    2004-01-01

    A heterosexual community can be analyzed as a marketplace in which men seek to acquire sex from women by offering other resources in exchange. Societies will therefore define gender roles as if women are sellers and men buyers of sex. Societies will endow female sexuality, but not male sexuality, with value (as in virginity, fidelity, chastity). The sexual activities of different couples are loosely interrelated by a marketplace, instead of being fully separate or private, and each couple's decisions may be influenced by market conditions. Economic principles suggest that the price of sex will depend on supply and demand, competition among sellers, variations in product, collusion among sellers, and other factors. Research findings show gender asymmetries (reflecting the complementary economic roles) in prostitution, courtship, infidelity and divorce, female competition, the sexual revolution and changing norms, unequal status between partners, cultural suppression of female sexuality, abusive relationships, rape, and sexual attitudes.

    This research examined the hypothesis that heterosexual men's motivation to differentiate themselves from gay men mediates the relationship between the antifemininity norm of masculinity and antigay prejudice. We assessed masculinity through three concepts: status, thoughness, and antifemininity. Participants then reported their perceived similarity with gay men and their antigay prejudice. The results showed that antifemininity was the best predictor of both perceived similarity and antigay prejudice: The more people endorsed the antifemininity norm, the more they perceived themselves as dissimilar from gay men and showed antigay prejudice. More important, perceived similarity mediated the effect of antifemininity on antigay prejudice. These findings provide direct evidence for the link between masculinity and the motivation to differentiate oneself from gay men, and they suggest that antigay prejudice accomplishes the identity function of maintaining unambiguous gender boundaries.

    Full Text Available The African penguin (Spheniscus demersus is an endangered seabird that breeds along the coast of Namibia and South Africa, and disease surveillance was identified as a priority for its conservation. Aiming for the establishment of baseline data on the presence of potential pathogens in this species, a comprehensive health assessment (blood smear examination, haematology, biochemistry and serology was conducted on samples obtained from 578 African penguins at 11 breeding colonies and a rehabilitation centre. There were 68 penguins that were seropositive for at least one of seven pathogens tested: avian encephalomyelitis virus, avian infectious bronchitis virus, avian reovirus, infectious bursal disease virus, Newcastle disease virus, Mycoplasma gallisepticum and Mycoplasma synoviae. All samples were seronegative for avian influenza virus subtypes H5 and H7 and infectious laryngotracheitis virus. The apparent prevalence of Babesia sp. and Borrelia sp. in blood smears was consistent with previous studies. Babesia-infected individuals had a regenerative response of the erythrocytic lineage, an active inflammatory response and hepatic function impairment. These findings indicate that African penguins may be exposed to conservation-significant pathogens in the wild and encourage further studies aiming for the direct detection and/or isolation of these microorganisms.

    2012-01-01

    Objective This qualitative analysis elucidates the potential elements of the intervention that may be effective in terms of a) increasing knowledge about HIV/AIDS in the members of this population; b) increasing the use of male condoms and the practice of mutual masturbation; and c) changing opinions toward male condom use and mutual masturbation. Methods Five heterosexual HIV-discordant couples participated in the adapted intervention, which consisted of four three-hour-long sessions. One month after the intervention, we conducted a qualitative semi-structured interview with every participant to evaluate issues related to the process and content of the activities comprising the intervention, the impact of the intervention, logistics, and recruitment and retention as well as to make a more general evaluation. The information was submitted to qualitative content analysis. Results After the intervention, participants reported having better attitudes regarding safer sex, particularly in terms of condom use. A reason given by the participants to feel more positive toward condom use and mutual masturbation was that these practices could prevent the infection of the HIV-negative partner. Conclusion This study provides important evidence of an intervention that promises to be efficacious in preventing some high-risk sexual behaviors among Latino HIV-discordant heterosexual couples. The evidence presented seems to suggest that an intervention that includes basic relevant information about HIV/AIDS, that explains the benefits of condom use and other safer sex options, and that provides effective negotiation and communication strategies could significantly reduce HIV transmission among these couples.

    Full Text Available Prevention of mother-to-child HIV transmission (PMTCT strategies include combined short-course antiretrovirals during pregnancy (Option A, triple-drug antiretroviral treament (ART during pregnancy and breastfeeding (Option B, or lifelong ART (Option B+. The WHO also recommends ART for HIV treatment and prevention of sexual transmission of HIV. The impact of PMTCT strategies on prevention of sexual HIV transmission of HIV is not known. We estimated the population-level impact of PMTCT interventions on heterosexual HIV transmission in southwestern Uganda and KwaZulu-Natal, South Africa, two regions with different HIV prevalence and fertility rates.We constructed and validated dynamic, stochastic, network-based HIV transmission models for each region. PMTCT Options A, B, and B+ were simulated over ten years under three scenarios: 1 current ART and PMTCT coverage, 2 current ART and high PMTCT coverage, and 3 high ART and PMTCT coverage. We compared adult HIV incidence after ten years of each intervention to Option A (and current ART at current coverage.At current coverage, Options B and B+ reduced heterosexual HIV incidence by about 5% and 15%, respectively, in both countries. With current ART and high PMTCT coverage, Option B+ reduced HIV incidence by 35% in Uganda and 19% in South Africa, while Option B had smaller, but meaningful, reductions. The greatest reductions in HIV incidence were achieved with high ART and PMTCT coverage. In this scenario, all PMTCT strategies yielded similar results.Implementation of Options B/B+ reduces adult HIV incidence, with greater effect (relative to Option A at current levels in Uganda than South Africa. These results are likely driven by Uganda's higher fertility rates.

    Recent epidemiological studies reported high prevalence rates of erectile dysfunction (ED) among younger heterosexual men (≤40). It has been suggested that this "epidemic" of ED is related to increased pornography use. However, empirical evidence for such association is currently lacking. This study analyzes associations between pornography use and sexual health disturbances among younger heterosexual men using four large-scale online samples from three European countries. The analyses were carried out using a 2011 cross-sectional online study of Croatian, Norwegian, and Portuguese men (Study 1; N = 2,737) and a 2014 cross-sectional online study of Croatian men (Study 2; N = 1,211). Chi-square test and multivariate logistic regression were used to explore the associations between pornography use and sexual difficulties. In Study 1, erectile difficulties, inability to reach orgasm, and a lack of sexual desire were measured using the Global Study of Sexual Attitudes and Behavior indicators. In Study 2, ED was measured with the abridged International Index of Erectile Function (IIEF-5). Delayed ejaculation and a decrease of sexual desire were assessed with one-item indicators. In Study 1, only the relationship between pornography use and ED among Croatian men was statistically significant (χ(2) [2] = 18.76, P pornography, moderate but not high frequency of pornography use increased the odds of reporting ED (adjusted odds ratio = 0.53, P pornography use and male sexual dysfunctions were observed. We found little evidence of the association between pornography use and male sexual health disturbances. Contrary to raising public concerns, pornography does not seem to be a significant risk factor for younger men's desire, erectile, or orgasmic difficulties. © 2015 International Society for Sexual Medicine.

  6. Cybersex addiction in heterosexual female users of internet pornography can be explained by gratification hypothesis.

    2014-08-01

    In the context of Internet addiction, cybersex is considered to be an Internet application in which users are at risk for developing addictive usage behavior. Regarding males, experimental research has shown that indicators of sexual arousal and craving in response to Internet pornographic cues are related to severity of cybersex addiction in Internet pornography users (IPU). Since comparable investigations on females do not exist, the aim of this study is to investigate predictors of cybersex addiction in heterosexual women. We examined 51 female IPU and 51 female non-Internet pornography users (NIPU). Using questionnaires, we assessed the severity of cybersex addiction in general, as well as propensity for sexual excitation, general problematic sexual behavior, and severity of psychological symptoms. Additionally, an experimental paradigm, including a subjective arousal rating of 100 pornographic pictures, as well as indicators of craving, was conducted. Results indicated that IPU rated pornographic pictures as more arousing and reported greater craving due to pornographic picture presentation compared with NIPU. Moreover, craving, sexual arousal rating of pictures, sensitivity to sexual excitation, problematic sexual behavior, and severity of psychological symptoms predicted tendencies toward cybersex addiction in IPU. Being in a relationship, number of sexual contacts, satisfaction with sexual contacts, and use of interactive cybersex were not associated with cybersex addiction. These results are in line with those reported for heterosexual males in previous studies. Findings regarding the reinforcing nature of sexual arousal, the mechanisms of learning, and the role of cue reactivity and craving in the development of cybersex addiction in IPU need to be discussed.

    Although the sexual transmission of HIV occurs in the context of an intimate relationship, preventive interventions with couples are scarce, particularly those designed for Hispanics. In this article, we present the effect of a pilot intervention directed to prevent HIV/AIDS in heterosexual couples in Puerto Rico. The intervention was theory-based and consisted of five three-hour group sessions. Primary goals included increasing male condom use and the practice of mutual masturbation as a safer sex method, and promoting favorable attitudes toward these behaviors. Twenty-six couples participated in this study. Fifteen were randomly assigned to the intervention group and eleven to a control group. Retention rates at post-intervention and follow-up were 82% for the whole sample. Results showed that there was a significant increase in the use of male condoms with main partners in the intervention group when compared with the control group. Couples in the intervention group also had better scores on secondary outcomes, such as attitudes toward condom use and mutual masturbation, HIV information, sexual decision-making, and social support. We found that these effects persisted over the three month follow up. A significant effect was also observed for the practice of mutual masturbation, but not for sexual negotiation. These results showed that promoting male condom use in dyadic interventions among heterosexual couples in Puerto Rico is feasible. Our findings suggest that because vaginal penetration has been constructed as the sexual script endpoint among many Hispanic couples, promoting other non-penetrative practices, such as mutual masturbation, may be difficult.

  8. HTLV-3 infection and AIDS: risk of spread by heterosexual contact.

    Craske, J

    1986-02-01

    This article reviews current research evidence on the natural history, epidemiology, and clinical features of acquired immunodeficiency disease (AIDS) and presents guidelines for controlling the sexual transmission of human lymphotropic virus type III (HTLV-III) infection. The rapid spread of HTLV-III infection through homosexual communities in the US and Europe and its association with promiscuity initially obscured the fact that heterosexual transmission is also a significant risk factor for infection. Public health workers and epidemiologists are examining which sexual practices are most associated with the transmission of HTLV-III infection. Case-control studies in homosexuals have suggested that promiscuity, passive anal intercourse, and other sexual practices associated with rectal trauma and bleeding correlate with infection. Similar studies involving heterosexuals have not been conducted. However, the following guidelines have been proposed for couples where 1 partner has been found to be positive for HTLV-III antibodies: 1) sexual partners should be confined to established relationships; 2) anal intercourse should be avoided, even if the male uses a condom; 3) no oral contact with semen should occur; 4) if vaginal intercourse is practiced, the use of condom is essential; and 5) the only practices that are free from risk of infection are mutual masturbation and hand caresses. Since a high proportion of children of women with HTLV-III develop severe immunodeficiency, it is undesirable for women who are HTLV-III antibody positive to become pregnant. Furthermore, there is evidence that women who are HTLV-III antibody positive are more likely to develop AIDS if they become pregnant. A reliable method of permanent or reversible contraception is recommended for these women. Finally, men who are antibody positive should not donate sperm to a sperm bank.

    Further studies are needed to evaluate the level of effectiveness and durability of HAART to reduce the risk of HIV sexual transmission in serodiscordant couples having unprotected sexual practices. A cross-sectional study was conducted with prospective cohort of heterosexual HIV serodiscordant couples where the only risk factor for HIV transmission to the uninfected partner (sexual partner) was the sexual relationship with the infected partner (index case). HIV prevalence in sexual partners at enrolment and seroconversions in follow-up were compared by antiretroviral treatment in the index partner, HIV plasma viral load in index cases and sexual risk exposures in sexual partners. In each visit, an evaluation of the risks for HIV transmission, preventive counselling and screening for genitourinary infections in the sexual partner was performed, as well as the determination of the immunological and virological situation and antiretroviral treatment in the index case. At enrolment no HIV infection was detected in 202 couples where the index case was taking HAART. HIV prevalence in sexual partners was 9.6% in 491 couples where the index case was not taking antiretroviral treatment (p<0.001). During follow-up there was no HIV seroconversion among 199 partners whose index case was taking HAART, accruing 7600 risky sexual exposures and 85 natural pregnancies. Among 359 couples whose index case was not under antiretroviral treatment, over 13,000 risky sexual exposures and 5 HIV seroconversions of sexual partners were recorded. The percentage of seroconversion among couples having risky sexual intercourse was 2.5 (95% confidence interval [CI]: 1.1-5.6) when the index case did not undergo antiretroviral treatment and zero (95% CI: 0-3.2) when the index case received HAART. The risk of sexual transmission of HIV from individuals with HAART to their heterosexual partners can become extremely low. Copyright © 2014. Published by Elsevier España, S.L.U.

    There is a notable gap between heterosexual men and women in frequency of orgasm during sex. Little is known, however, about sexual orientation differences in orgasm frequency. We examined how over 30 different traits or behaviors were associated with frequency of orgasm when sexually intimate during the past month. We analyzed a large US sample of adults (N = 52,588) who identified as heterosexual men (n = 26,032), gay men (n = 452), bisexual men (n = 550), lesbian women (n = 340), bisexual women (n = 1112), and heterosexual women (n = 24,102). Heterosexual men were most likely to say they usually-always orgasmed when sexually intimate (95%), followed by gay men (89%), bisexual men (88%), lesbian women (86%), bisexual women (66%), and heterosexual women (65%). Compared to women who orgasmed less frequently, women who orgasmed more frequently were more likely to: receive more oral sex, have longer duration of last sex, be more satisfied with their relationship, ask for what they want in bed, praise their partner for something they did in bed, call/email to tease about doing something sexual, wear sexy lingerie, try new sexual positions, anal stimulation, act out fantasies, incorporate sexy talk, and express love during sex. Women were more likely to orgasm if their last sexual encounter included deep kissing, manual genital stimulation, and/or oral sex in addition to vaginal intercourse. We consider sociocultural and evolutionary explanations for these orgasm gaps. The results suggest a variety of behaviors couples can try to increase orgasm frequency.

    The purpose of this study was to compare sexual-minority and heterosexual youths' exposure to sexual abuse off-line, problematic sexual meetings off-line with person/s met online and online harassment with regard to prevalence, psychological well-being and support seeking. A nationally representative sample of 3,432 Swedish high school seniors completed an anonymous school-based survey about sexuality, health, sexual abuse and online-related sexual victimisation or harassment. Sexual-minority adolescents reported a greater rate of sexual abuse, problematic sexual meetings off-line with person/s met online and online harassment, compared to heterosexual youth. When compared to non-victimised heterosexual adolescents, victimised heterosexual adolescents and non-victimised and victimised sexual-minority adolescents reported more psychiatric symptoms, lower self-esteem and a weaker sense of coherence. Same-sex sexual orientation was related to more psychiatric symptoms, lower self-esteem and a weaker sense of coherence even when controlled for victimisation and gender. Compared to victimised heterosexual adolescents, victimised sexual-minority adolescents were more likely to seek support because of sexual abuse (females) or Internet-related problems (males and females). Results for sexual-minority youth were basically the same whether sexual orientation was assessed as sexual identity or as sexual or emotional attraction. Health care providers are challenged to not only provide the same care to sexual-minority youth who seek counselling or psychiatric treatment for mental health problems or problems related to victimisation that all adolescents should receive but also to find ways to address topics like prevention of sexual abuse and risk-taking behaviour online or off-line.

    Racial discrimination is a common stressor for African Americans, with negative consequences for mental and physical well-being. It is likely that these effects extend into the family, but little research has examined the association between racial discrimination and couple functioning. This study used dyadic data from 344 rural, predominantly low-income heterosexual African American couples with an early adolescent child to examine associations between self-reported racial discrimination, psychological and physical aggression, and relationship satisfaction and instability. Experiences of discrimination were common among men and women and were negatively associated with relationship functioning. Specifically, men reported higher levels of psychological aggression and relationship instability if they experienced higher levels of racial discrimination, and women reported higher levels of physical aggression if they experienced higher levels of racial discrimination. All results replicated when controlling for financial hardship, indicating unique effects for discrimination. Findings suggest that racial discrimination may be negatively associated with relationship functioning among African Americans and call for further research on the processes underlying these associations and their long-term consequences.

    2010-04-01

    Testing of patients who are deemed to be at high risk for TORCH pathogens, e.g., pregnant women, their fetuses, neonates, and acquired immunodeficiency syndrome (AIDS) patients, is important so that specific treatment can be initiated. This study included 1,857 such patients between 2005 and 2008. Logistic regression was used to evaluate factors associated with Toxoplasma gondii seropositivity. Among 823 women of childbearing age, 35.1% and 5.2% tested positive for T. gondii IgG and IgM, respectively. Three infants nationality, positive cytomegalovirus (CMV) and herpes simplex virus (HSV)-1 serostatus, and negative rubella IgG results. The decreasing prevalence of IgM antibodies between 2005 and 2008 suggested that exposure to T. gondii from food or environmental sources declined over this period in Qatar. Population-based studies of newborns would be helpful to accurately estimate incidence of congenital toxoplasmosis.

    In this study, one hundred serum samples from healthy people and patients with rheumatoid arthritis (RA) were analyzed. Standard immunoassays for detection of 10 different RA markers and analysis of glycan markers on antibodies in 10 different assay formats with several lectins were applied for each serum sample. A dataset containing 2000 data points was data mined using artificial neural networks (ANN). We identified key RA markers, which can discriminate between healthy people and seropositive RA patients (serum containing autoantibodies) with accuracy of 83.3%. Combination of RA markers with glycan analysis provided much better discrimination accuracy of 92.5%. Immunoassays completely failed to identify seronegative RA patients (serum not containing autoantibodies), while glycan analysis correctly identified 43.8% of these patients. Further, we revealed other critical parameters for successful glycan analysis such as type of a sample, format of analysis and orientation of captured antibodies for glycan analysis.

    Full Text Available Background. Syphilis research has neglected the prevalence of the disease among psychiatric patients, and traditional syphilis screening has been reported as inadequate. Objectives. (i To assess the syphilis prevalence among psychiatric patients; (ii to compare psychiatric diagnoses of syphilis-infected and -uninfected patients; (iii to assess self-reported high-risk sexual behaviour; (iv to establish syphilis/HIV co-morbidity; and (v to investigate the performance of the rapid plasma reagin (RPR test in syphilis screening, compared with the Treponema pallidum haemagglutination (TPHA test. Methods. Psychiatric inpatients at Weskoppies Hospital, Pretoria, who consented to participate in the study (N=195 were categorised according to gender and length of admission (long-term or recent. Non-treponemal RPR, confirmatory TPHA, HIV-rapid and HIV enzyme-linked immunosorbent assay (ELISA tests were performed. A reactive TPHA test was used to diagnose syphilis. Results. The estimated prevalence of syphilis was 11.7%. There was no significant association between TPHA sero-positivity and primary psychiatric diagnosis or self-reported high-risk sexual behaviour. Significant co-morbidity existed between syphilis and HIV (p=0.012. Compared with the TPHA test, the RPR test performed poorly, identifying only 2/23 patients who had a sero-positive TPHA test (8.7% sensitivity and 100% specificity. Conclusions. The prevalence of syphilis was higher than anticipated, supporting the need for routine testing. The significant co-morbidity and alarming prevalence of HIV and syphilis warrant testing for both conditions in all psychiatric admissions. Current syphilis screening with a single RPR test is inadequate; both RPR and TPHA tests should be performed.

  7. [HCV and HBV seropositivity in university students of the State of Nuevo Leòn, Mexico].

    Viral hepatitis is a contagious disease. Patients infected with hepatitis B virus (HBV) or hepatitis C virus (HCV), may be either chronically symptomatic or asymptomatic, and suffer cirrhosis and high risk of hepatic carcinoma. Asymptomatic carriers of HBV surface antigen (HBs-Ag) or with anti-HCV antibodies are potentially infectious, and therefore a risk to public health. This work seeks to establish the frequency of seropositivity for HBs-Ag and anti-HCV antibodies in a population of 774 newly accepted students of the Medical School of the Autonomous University of Nuevo Leon, whose average age was 18 years. Second generation ELISA test were used to screen for HBs-Ag and anti-HCV antibodies. HBs-Ag was confirmed by a neutralization test and anti-HCV antibodies were confirmed by a RIBA test. Three sera were positive for HBs-Ag by ELISA and only one serum (0.13% of analyzed samples) was confirmed by the neutralization technique. On the other hand 12 sera were positive for anti-HCV antibodies by ELISA, and eight of these were confirmed by RIBA (1.03% of the analyzed samples). Intensive reactivity bands were found in two sera, and weak reactivity bands were found in six sera. ELISA screening for anti-HCV antibodies showed 0.5% of false positives. This study shows that the frequency of anti-HCV antibodies is 7.95% times higher than that found for HBs-Ag. All seropositive patients were asymptomatic and potentially infective. This demonstrates the need to routinely screen for HBs-Ag and anti-HCV antibodies to establish the prevalence of these diseases in our area.

    Highly pathogenic avian influenza A (HPAI) H5N1 viruses have infected poultry and wild birds on three continents with more than 600 reported human cases (59% mortality) since 2003. Wild aquatic birds are the natural reservoir for avian influenza A viruses, and migratory birds have been documented with HPAI H5N1 virus infection. Since 2005, clade 2.2 HPAI H5N1 viruses have spread from Asia to many countries. We conducted a cross-sectional seroepidemiological survey in Anchorage and western Alaska to identify possible behaviors associated with migratory bird exposure and measure seropositivity to HPAI H5N1. We enrolled rural subsistence bird hunters and their families, urban sport hunters, wildlife biologists, and a comparison group without bird contact. We interviewed participants regarding their exposures to wild birds and collected blood to perform serologic testing for antibodies against a clade 2.2 HPAI H5N1 virus strain. Hunters and wildlife biologists reported exposures to wild migratory birds that may confer risk of infection with avian influenza A viruses, although none of the 916 participants had evidence of seropositivity to HPAI H5N1. We characterized wild bird contact among Alaskans and behaviors that may influence risk of infection with avian influenza A viruses. Such knowledge can inform surveillance and risk communication surrounding HPAI H5N1 and other influenza viruses in a population with exposure to wild birds at a crossroads of intercontinental migratory flyways. © 2014 The Authors.

    Full Text Available The effect of HIV infection on the prevalence and the rate of progression of chronic periodontitis is not clear. The aim of this study was to compare parameters associated with the severity of chronic periodontitis in terms of periodontal probing depths, gingival recession, plaque indexes, and bleeding indexes of HIV-seropositive subjects and healthy age-matched control subjects, and of HIV-seropositive subjects on highly active antiretroviral therapy and those not receiving such treatment. Two cohorts of subjects with chronic periodontitis were recruited for this study over a period of six months. There were 30 HIV-seropositive subjects, and 30 control subjects. Periodontal probing depths, gingival marginal recession, plaque indexes, and bleeding indexes were compared by HIV serostatus, the use of highly active antiretroviral therapy, and CD4+ T-cell counts. All participants were black persons between the age of 18 and 45 and were of a similar socioeconomic status and age. The results of this study indicate that chronic periodontitis in HIV-seropositive subjects is similar in terms of mean periodontal probing depth, gingival marginal recession, plaque index, and bleeding index to that in healthy age-matched control subjects, and a low CD4+ T-cell count does not appear to be a risk factor for increased severity of chronic periodontitis.

    Full Text Available Despite known health disparities for sexual minorities, few studies have described sexual function by sexual orientation using a robust approach to measurement of sexual function. We compared recent sexual function and satisfaction by sexual orientation among English-speaking US adults.Cross-sectional surveys were administered by KnowledgePanel® (GfK, an online panel that uses address-based probability sampling and is representative of the civilian, noninstitutionalized US population. Data were collected in 2013 from the general population (n = 3314, 35% response rate and in 2014 from self-identified lesbian, gay, and bisexual adults (n = 1011, 50% response rate. Sexual function and satisfaction were measured using the Patient-Reported Outcomes Measurement Information System® Sexual Function and Satisfaction measure version 2.0 (PROMIS SexFS v2. The PROMIS SexFS v2 is a comprehensive, customizable measurement system with evidence for validity in diverse populations. A score of 50 (SD 10 on each domain corresponds to the average for US adults sexually active in the past 30 days. We adjusted all statistics for the complex sample designs and report differences within each sex where the 95% CIs do not overlap, corresponding to p<0.01. Among US men who reported any sexual activity in the past 30 days, there were no differences in erectile function or orgasm-ability. Compared to heterosexual men, sexual minority men reported higher oral dryness and lower orgasm-pleasure and satisfaction. Compared to heterosexual men, gay men reported lower interest, higher anal discomfort and higher oral discomfort. Among sexually active women, there were no differences in the domains of vulvar discomfort-clitoral, orgasm-pleasure, or satisfaction. Compared to heterosexual women, sexual minority women reported higher oral dryness. Lesbian women reported lower vaginal discomfort than other women; lesbian women reported higher lubrication and orgasm-ability than

    About 40% of the Italian HIV-1 epidemic due to non-B variants is sustained by F1 clade, which circulates at high prevalence in South America and Eastern Europe. Aim of this study was to define clade F1 origin, population dynamics and epidemiological networks through phylogenetic approaches. We analyzed pol sequences of 343 patients carrying F1 subtype stored in the ARCA database from 1998 to 2009. Citizenship of patients was as follows: 72.6% Italians, 9.3% South Americans and 7.3% Rumanians. Heterosexuals, Homo-bisexuals, Intravenous Drug Users accounted for 58.1%, 24.0% and 8.8% of patients, respectively. Phylogenetic analysis indicated that 70% of sequences clustered in 27 transmission networks. Two distinct groups were identified; the first clade, encompassing 56 sequences, included all Rumanian patients. The second group involved the remaining clusters and included 10 South American Homo-bisexuals in 9 distinct clusters. Heterosexual modality of infection was significantly associated with the probability to be detected in transmission networks. Heterosexuals were prevalent either among Italians (67.2%) or Rumanians (50%); by contrast, Homo-bisexuals accounted for 71.4% of South Americans. Among patients with resistant strains the proportion of clustering sequences was 57.1%, involving 14 clusters (51.8%). Resistance in clusters tended to be higher in South Americans (28.6%) compared to Italian (17.7%) and Rumanian patients (14.3%). A striking proportion of epidemiological networks could be identified in heterosexuals carrying F1 subtype residing in Italy. Italian Heterosexual males predominated within epidemiological clusters while foreign patients were mainly Heterosexual Rumanians, both males and females, and South American Homo-bisexuals. Tree topology suggested that F1 variant from South America gave rise to the Italian F1 epidemic through multiple introduction events. The contact tracing also revealed an unexpected burden of resistance in epidemiological

    Annual HIV testing is recommended for populations at-risk for HIV in the United States, including heterosexuals geographically connected to urban high-risk areas (HRA) with elevated rates of HIV prevalence and poverty, who are primarily African American/Black or Hispanic. Yet this subpopulation of "individuals residing in HRA" (IR-HRA) evidence low rates of regular HIV testing. HIV stigma is a recognized primary barrier to testing, in part due to its interaction with other stigmatized social identities. Guided by social-cognitive and intersectionality theories, this qualitative descriptive study explored stigma as a barrier to HIV testing and identified ways IR-HRA manage stigma. In 2012-2014, we conducted in-depth qualitative interviews with 31 adult IR-HRA (74% male, 84% African American/Black) with unknown or negative HIV status, purposively sampled from a larger study for maximum variation on HIV testing experiences. Interviews were audio-recorded and professionally transcribed verbatim. Data were analyzed using a systematic content analysis approach that was both theory-driven and inductive. Stigma was a primary barrier to HIV testing among IR-HRA. In the context of an under-resourced community, HIV stigma was experienced as emerging from, and being perpetuated by, health care organizations and educational institutions, as well as community members. Participants noted it was "better not to know" one's HIV status, to avoid experiencing HIV-related stigma, which could interact with other stigmatized social identities and threaten vital social relationships, life chances, and resources. Yet most had tested for HIV previously. Factors facilitating testing included health education to boost knowledge of effective treatments for HIV; understanding HIV does not necessitate ending social relationships; and tapping into altruism. In the context of economic and social inequality, HIV stigma operates on multiple, intersecting layers. IR-HRA struggle with an aversion to

    Human papillomavirus vaccines have demonstrated remarkable efficacy against persistent infection and disease associated with vaccine-incorporated genotypes and a degree of efficacy against some genetically related, non-vaccine-incorporated genotypes. The vaccines differ in the extent of cross-protection against these non-vaccine genotypes. Data supporting the role for neutralizing antibodies as a correlate or surrogate of cross-protection are lacking, as is a robust assessment of the seroconversion rates against these non-vaccine genotypes. We performed a systematic review and meta-analysis of available data on vaccine-induced neutralizing antibody seropositivity to non-vaccine incorporated HPV genotypes. Of 304 articles screened, 9 were included in the analysis representing ca. 700 individuals. The pooled estimate for seropositivity against HPV31 for the bivalent vaccine (86%; 95%CI 78-91%) was higher than that for the quadrivalent vaccine (61%; 39-79%; p=0.011). The pooled estimate for seropositivity against HPV45 for the bivalent vaccine (50%; 37-64%) was also higher than that for the quadrivalent vaccine (16%; 6-36%; p=0.007). Seropositivity against HPV33, HPV52 and HPV58 were similar between the vaccines. Mean seropositivity rates across non-vaccine genotypes were positively associated with the corresponding vaccine efficacy data reported from vaccine trials. These data improve our understanding of vaccine-induced functional antibody specificity against non-vaccine incorporated genotypes and may help to parameterize vaccine-impact models and improve patient management in a post-vaccine setting.

    This analysis compared the frequency of persistent Trichomonas vaginalis (TV) among HIV-seropositive and HIV-seronegative women. Data were obtained from women enrolled in an open cohort study of sex workers in Kenya. Participants were examined monthly, and those diagnosed as having TV by saline microscopy were treated with single-dose 2 g oral metronidazole. All women on antiretroviral therapy (ART) used nevirapine-based regimens. Generalized estimating equations with a logit link were used to compare the frequency of persistent TV (defined as the presence of motile trichomonads by saline microscopy at the next examination visit within 60 days) by HIV status. Three-hundred sixty participants contributed 570 infections to the analysis (282 HIV-seropositive and 288 HIV-seronegative). There were 42 (15%) persistent infections among HIV-seropositive participants versus 35 (12%) among HIV-seronegative participants (adjusted odds ratio, 1.14; 95% confidence interval [CI], 0.70-1.87). Persistent TV was highest among HIV-seropositive women using ART (21/64 [33%]) compared with HIV-seropositive women not using ART (21/217 [10%]). Concurrent bacterial vaginosis (BV) at TV diagnosis was associated with an increased likelihood of persistent TV (adjusted odds ratio, 1.90; 95% confidence interval, 1.16-3.09). The frequency of persistent TV infection after treatment with single-dose 2 g oral metronidazole was similar by HIV status. Alternative regimens including multiday antibiotic treatment may be necessary to improve cure rates for women using nevirapine-based ART and women with TV and concurrent BV.

    Clinical trials of the human rotavirus vaccine Rotarix™ (RV1) have demonstrated significant reductions in severe rotavirus gastroenteritis (RVGE) in children worldwide. However, no correlate of vaccine efficacy (VE) has yet been established. This paper presents 2 analyses which aimed to investigate whether serum anti-RV IgA measured by ELISA 1 or 2 mo post-vaccination can serve as a correlate of efficacy against RVGE: (1) In a large Phase III efficacy trial (Rota-037), the Prentice criteria for surrogate endpoints was applied to anti-RV IgA seropositivity 1 mo post-vaccination. These criteria determine whether a significant vaccine group effect can be predicted from the surrogate, namely seropositivity (anti-RV IgA concentration>20 U/mL); (2) Among other GSK-sponsored RV1 VE studies, 8 studies which assessed immunogenicity at 1 or 2 mo post-vaccination in all or a sub-cohort of enrolled subjects and had at least 10 RVGE episodes were included in a meta-analysis to measure the regression between clinical VE and VE predicted from immunogenicity (VE1). In Rota-037, anti-RV IgA seropositivity post-vaccination was associated with a lower incidence of any or severe RVGE, however, the proportion of vaccine group effect explained by seropositivity was only 43.6% and 32.7% respectively. This low proportion was due to the vaccine group effect observed in seronegative subjects. In the meta-analysis, the slope of the regression between clinical VE and VE1 was statistically significant. These two independent analyses support the hypothesis that post-vaccination anti-RV IgA seropositivity (antibody concentration ≥20 U/mL) may serve as a useful correlate of efficacy in clinical trials of RV1 vaccines.

    Substance use is prevalent among African American men living in urban communities. The impact of substance use on the social, psychological, and physical health of African American men has important public health implications for families, communities, and society. Given the adverse consequences of alcohol and drug abuse within communities of color, this study evaluated the relationship between city stress, alcohol consumption, and drug use among African American men. Eighty heterosexual, African American men, 18 to 29 years old, completed psychosocial risk assessments that assessed substance use and city stress. Multiple logistic regression analyses, controlling for age, indicated that participants reporting high levels of urban stress, relative to low levels of urban stress, were more likely to report a history of marijuana use (AOR = 5.19, p = .05), history of ecstasy and/or GHB use (AOR = 3.34, p = .04), having family/friends expressing strong concerns about their illicit drug use (AOR = 4.06, p = .02), and being unable to remember what happened the night before due to drinking (AOR = 4.98, p = .01). African American men living within the confines of a stressful urban environment are at increased risk for exposure to and utilization of illicit substances. Culturally competent public health interventions for substance use/abuse should address psychological factors, such as stress and neighborhood violence.

This exploratory study addressed this gap through six focus groups with 41 Black, low- to middle-income heterosexual men aged 19 to 51 years in Philadelphia, PA. Analyses highlighted two explicit ideologies of masculinity: that Black men should have sex with multiple women, often concurrently, and that Black men should not be gay or bisexual. Analyses also identified two implicit masculinity ideologies: the perception that Black heterosexual men cannot decline sex, even risky sex, and that women should be responsible for condom use.

    Objective: The goal of this research was to understand the demographic distribution and related factors of non-marital and non-commercial heterosexual transmission (non-commercial transmission) for HIV/AIDS (human immunodeficiency virus/acquired immunodeficiency syndrome). Methods: Data related to HIV/AIDS infected by non-marital heterosexual transmission and whose present address was in Qian Dongnan, were collected from Information System on the HIV/AIDS Prevention and Control. Information included demographic characteristics, the members of non-marital sex partners, transmission path, detection source, CD4(+)T lymphocyte level, et al. cases belong to homosexual history, injective drug use or non-classified non-marital heterosexuality transmission were excluded, totally collect HIV/AIDS 919 cases. Multivariate logistic regressions were used to analyze potential factors associated with non-marital and non-commercial heterosexual transmission. In addition, in March and June 2017, using a convenience sampling, we conducted one-to-one interviews among 10 HIV/AIDS who were infected by non-marital heterosexuality and had non-marital and non-commercial heterosexual experience in Kaili Center for Disease Control and Prevention. The content of the interview included basic information, sexual orientation, the main place of making friends and sexual behavior, attitude to commercial heterosexuality and non-martial and non-commercial heterosexuality and so on. Results: Out of the 919 cases, 645 (70.2%) were male, the proportion of non-commercial transmission was 55.06% (506). The proportion of female HIV/AIDS with non-commercial transmission was 84.7% (232), which was higher than male (42.5%(274)) (χ(2)=138.35, Pcommercial transmission was 61.5% (275), which was higher than other religion (52.2%(412)) (χ(2)=6.32, P= 0.012). The proportion of HIV/AIDS with non-commercial transmission who had 0-5 non-marital sexual partners was 58.8% (498), which was higher than who had>5 non

    The aim of this study was to characterise the clinical features of adenovirus urethritis in men and to compare the frequency of these between heterosexual men and men who have sex with men (MSM). This was a review of the clinical and laboratory information from men diagnosed with PCR-confirmed adenovirus urethritis at the Melbourne Sexual Health Centre between January 2006 and April 2014. 102 adenovirus urethritis cases were reported, among which 61 were heterosexual men and 41 MSM. Eighty-nine per cent (n=91) had signs of meatitis or conjunctivitis: 51% had meatitis only; 32% meatitis together with conjunctivitis and 6% with conjunctivitis only. The distribution of symptoms and signs was similar among heterosexual men and MSM (p values >0.1). Adenovirus was the sole pathogen found in 93% of cases, excluding gonorrhoea, chlamydia, Mycoplasma genitalium and herpes simplex virus.

    Heterosexual anal and oral sex are related to the acquisition of sexually transmitted infections, including human immunodeficiency virus infection. We examined the correlates of heterosexual anal and oral sex in the general population, using data from the National Survey of Family Growth. The sample included 12,571 men and women aged 15-44 years (79% response rate). One-third of men and women had ever had anal sex, and three-quarters had ever had oral sex. Condom use during last oral or anal sex was relatively uncommon. In separate models for men and women, having ever had anal sex was associated with white race, age of 20-44 years, and having had a non-monogamous sex partner. White race, age of 20-44 years, being married, and having higher numbers of lifetime sex partners were related to having ever given oral sex in men and women. Giving oral sex was associated with having a non-monogamous sex partner in men. Ever receiving oral sex was associated with white race and a non-monogamous sex partner in men and women. It would be beneficial to track the prevalence of heterosexual anal and oral sex and associated condom use on a more frequent basis.

    Hegemonic masculine norms (HMN), which promote sexual risk-taking among males and the subordination of women, are believed to play a key role in the HIV epidemic among heterosexual couples in South Africa (SA). Sexual communication self-efficacy (SCSE) (i.e., a couple's confidence in their ability to communicate about HIV prevention) may be a key leverage point for increasing HIV prevention behaviors among this population. We interviewed 163 sexually active heterosexual couples in Soweto, SA to investigate the association between SCSE, HMN, and consistent condom use. We collected information on demographics, relationship dynamics, and sexual activity. We utilized the SCSE scale to measure couples' SCSE, and a subscale of the Gender Equitable Men scale to measure HMN among males. We performed bivariate and multivariable analyses to determine the association of consistent condom use with couples' SCSE as well as the male partner's endorsement of HMN. We found that couples with higher SCSE have greater odds of consistent condom use (adjusted odds ratio [AOR] = 1.30, 95% CI: 1.15-1.47). Furthermore, male endorsement of HMN was found to be negatively associated with consistent condom use among couples (AOR = 0.47, 95% CI: 0.24-0.89). Joint HIV serostatus was not significantly associated with the outcome. Future interventions that equip heterosexual couples with sexual communication skills, while simultaneously promoting more gender equitable norms, may increase consistent condom use and thereby reduce the transmission of HIV among this at-risk population.

    Women who inject drugs (WWID) are vulnerable to a range of harms, including exposure to sexually transmitted and blood-borne infections, abusive relationships, physical and sexual violence and mental health issues. Lesbians and bisexual women are at greater risk than heterosexual women for substance use disorders. This study aimed to compare a large sample of heterosexual, bisexual, and lesbian WWID and to identify correlates of sexual orientation. The Australian Needle and Syringe Program (NSP) Survey is an annual cross-sectional survey. People who inject drugs (PWID) who attend NSP services are invited to complete a brief self-administered questionnaire and provide a capillary dried blood spot. Of 22,791 survey respondents between 2004-2013, one third were women (n=7,604). Analyses were restricted to the first participation record for each respondent. Of the 5,378 individual women, 4,073 (76%) identified as heterosexual, 1,007 (19%) identified as bisexual, and 298 (6%) identified as lesbian. HIV prevalence was low (sexual orientation and risk behavior identified bisexual orientation as independently associated with increased risk. Services that target PWID need to recognise and address a broad range of sexual identities and behaviors. Future research should explore reasons for increased risk in sexual minority women.

    In recent history, heterosexual allies have played an integral role in promoting change for lesbian, gay, bisexual, and transgender (LGBT) populations in the United States; however, questions have been raised as to what drives heterosexual allies to promote change via activism. To delineate factors important in engagement in activism, 207 self-identified heterosexual allies completed an online survey measuring components associated with LGBT activism using Bandura's (1986) model of triadic reciprocal determinism: personal factors (ally identity, social justice self-efficacy and outcome expectations, empathetic perspective taking, and gender) and environmental factors (social justice related supports and barriers, positive marginality, and education level) to predict behaviors (LGBT activism). A hierarchical multiple regression analysis revealed a model accounting for 62% of the variance in LGBT activism, with dimensions of ally identification, social justice self-efficacy, outcome expectations, and education level emerging as significant predictors of engagement in activism behaviors. Empathetic perspective taking and social justice related barriers predicted lack of engagement in LGBT activism, however. Supporting the notion that personal and environmental factors simultaneously impact engagement in LGBT activism. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    Two key components of end-of-life planning are (1) informal discussions about future care and other end-of-life preferences and (2) formal planning via living wills and other legal documents. We leverage previous work on the institutional aspects of marriage and on sexual-minority discrimination to theorize why and how heterosexual, gay, and lesbian married couples engage in informal and formal end-of-life planning. We analyze qualitative dyadic in-depth interviews with 45 midlife gay, lesbian, and heterosexual married couples ( N = 90 spouses). Findings suggest that same-sex spouses devote considerable attention to informal planning conversations and formal end-of-life plans, while heterosexual spouses report minimal formal or informal planning. The primary reasons same-sex spouses give for making end-of-life preparations are related to the absence of legal protections and concerns about discrimination from families. These findings raise questions about future end-of-life planning for same- and different-sex couples given a rapidly shifting legal and social landscape.

  17. Maintaining distinctions under threat: heterosexual men endorse the biological theory of sexuality when equality is the norm.

    According to social identity theory, group members sometimes react to threats to their group's distinctiveness by asserting the distinctiveness of their group. In four studies (n = 261) we tested the hypothesis that heterosexual men with a greater propensity to be threatened by homosexuality would react to egalitarian norms by endorsing biological theories of sexuality. Heterosexual men, but not women, with narrow prototypes of their gender in-group endorsed biological theories the most (Study 1). Heterosexual men with higher gender self-esteem, with heterosexist attitudes, who endorsed traditional gender roles, and with narrow prototypes of their gender in-group, endorsed the biological theories more when egalitarian norms rather than anti-egalitarian norms (Studies 2 and 3) or pro-minority ideologies that emphasized group differences (Study 4) were made salient. These findings show group-level reactive distinctiveness among members of a high-status group in a context of threat to the unique privileges that they once enjoyed. © 2013 The British Psychological Society.

    Empirical research suggests that emotional response during sexual activity discriminates between sexually functional and dysfunctional heterosexual men and women, with clinics presenting lower positive and higher negative affect. However, there is no evidence about the role of emotions in gay men and lesbian women with sexual problems. The present study analyzed affective states during sexual activity in homosexual and heterosexual men and women, with and without sexual problems. Participants in this study were 156 men and 168 women. A 2 (group) × 2 (sexual orientation) multivariate analysis of variance was performed. Participants completed a web-survey assessing sexual functioning and the Positive Affect-Negative Affect Scale. Findings indicated a main effect of group, with groups with sexual problems reporting significantly more negative and lower positive affect compared with men and women without sexual problems, regardless of sexual orientation. However, findings have also shown an interaction effect in the male sample with gay men, contrary to heterosexual men, reporting similar affective responses regardless of having a sexual dysfunction or not. Overall, findings emphasize the role of affective responses during sexual activity in men and women with sexual problems, suggesting the importance of addressing emotional responses in assessment and treatment of sexual problems in individuals with different sexual orientations.

  19. "I kiss them because I love them": the emergence of heterosexual men kissing in British institutes of education.

    2012-04-01

    In this article, we combined data from 145 interviews and three ethnographic investigations of heterosexual male students in the U.K. from multiple educational settings. Our results indicate that 89% have, at some point, kissed another male on the lips which they reported as being non-sexual: a means of expressing platonic affection among heterosexual friends. Moreover, 37% also reported engaging in sustained same-sex kissing, something they construed as non-sexual and non-homosexual. Although the students in our study understood that this type of kissing remains somewhat culturally symbolized as a taboo sexual behavior, they nonetheless reconstructed it, making it compatible with heteromasculinity by recoding it as homosocial. We hypothesize that both these types of kissing behaviors are increasingly permissible due to rapidly decreasing levels of cultural homophobia. Furthermore, we argue that there has been a loosening of the restricted physical and emotional boundaries of traditional heteromasculinity in these educational settings, something which may also gradually assist in the erosion of prevailing heterosexual hegemony.

    Intimate partner violence (IPV) victimization is linked to sexual risk exposure among women. However, less is known about the intersection of IPV perpetration and sexual risk behavior among men. This study used data from a diverse, community sample of 334 heterosexually active young men, aged 18 to 25, across the United States to examine whether and how men with distinct IPV-related behavior patterns differed in sexual risk-related behavior and attitudes. Participants were recruited and surveyed online, and grouped conceptually based on the types of IPV perpetration behavior(s) used in a current or recent romantic relationship. Groups were then compared on relevant sexual risk variables. Men reporting both physical abuse and sexual coercion against intimate partners reported significantly higher numbers of lifetime partners, higher rates of nonmonogamy, greater endorsement of nonmonogamy, and less frequent condom use relative to nonabusive men or those reporting controlling behavior only. This group also had higher sexually transmitted infection (STI) exposure compared to men who used controlling behavior only and men who used sexual coercion only. Findings suggest that interventions with men who use physical and sexual violence need to account for not only the physical and psychological harm of this behavior but also the sexual risk to which men may expose their partners.

    The various changes of sexuality, including decreased sexual desire and erectile dysfunction, are also accompanied with aging. To understand the effect of aging on sexuality, we explored the relationship between age and the visual erotic stimulation-related brain response in sexually active male subjects. Twelve healthy, heterosexual male subjects (age 22-47 years) were recorded the functional magnetic resonance imaging (fMRI) signals of their brain activation elicited by passive viewing erotic (ERO), happy-faced (HA) couple, food and nature pictures. Mixed effect analysis and correlation analysis were performed to investigate the relationship between the age and the change of brain activity elicited by erotic stimuli. Our results showed age was positively correlated with the activation of right occipital fusiform gyrus and amygdala, and negatively correlated with the activation of right insula and inferior frontal gyrus. These findings suggest age might be related with functional decline in brain regions being involved in both interoceptive sensation and prefrontal modulation while it is related with the incremental activity of the brain region for early processing of visual emotional stimuli in sexually healthy men.

    We investigated the prevalence of various genital organisms in 268 men with (cases) and 237 men without (controls) urethral symptoms/signs (urethral discharge, dysuria and/or urethral irritation) from two sexual health clinics in Sydney between April 2006 and November 2007. The presence of urethral symptoms/signs was defined as non-gonococcal urethritis (NGU) for this study. Specific aims were to investigate the role of Ureaplasma urealyticum in NGU and the prevalence of Mycoplasma genitalium in our population. Multiplex polymerase chain reaction-based reverse line blot (mPCR/RLB) assay was performed to detect 14 recognized or putative genital pathogens, including Chlamydia trachomatis, M. genitalium, U. urealyticum and U. parvum. U. urealyticum was associated with NGU in men without another urethral pathogen (odds ratio [OR] 2.0, 95% confidence interval [CI] 1.1-3.8; P = 0.04); this association remained after controlling for potential confounding by age and history of unprotected vaginal sex in the last four weeks (OR 2.0, 95% CI: 1.1-3.9; P = 0.03). C. trachomatis (OR 7.5, P urethral pathogens. Further research should investigate the role of U. urealyticum subtypes among heterosexual men with NGU.

  3. Expressions of commitment and independence: Exploring men’s emotional responsibility in heterosexual couple relationships

    Full Text Available This paper examines men’s contributions to the division of emotional labour in heterosexual couple relationships by exploring the dimensions of commitment and independence, and how couples deal with challenges. The study is based on individual interviews with each of the partners in ten urban middle-class couples in Norway. The results indicate diversity in middle-class men’s approaches to emotional responsibility, which is expressed through three models. The model of shared responsibility implies that the man’s contributions in the relationship represent expressions of responsive commitment. The man finds a balance between giving priority to his personal interests and considering shared interests; a pattern we refer to as collaborative independence, and he shares the responsibility for coping with challenges with his partner. The model of gendered responsibility implies that the man’s contributions in the relationship are characterized by non-responsive commitment. The man gives priority to his personal interests in a way we refer to as conflicting independence, and refrains from sharing the responsibility for coping with challenges with his partner. Finally, a third model, termed partial responsibility, is also evident in the data. This model is a combination of collaborative independence and non-responsive commitment, and may represent a phase of transition towards collaboration on an equal basis. A discussion of interpretations of the diversity in men’s approaches to commitment and independence concludes the paper.

    While many studies have examined correlates of trading sex for money, few have examined factors associated with exclusive trading of sex for drugs. We identified sociodemographic, behavioral, and psychological correlates of trading sex for methamphetamine in a sample of HIV-negative heterosexual men and women who were enrolled in a sexual risk reduction intervention in San Diego, California. Of 342 participants, 26% overall (21% of males and 31% of females) reported trading sex for methamphetamine in the past two months. Multiple logistic regression analysis revealed that recently trading sex for methamphetamine was independently associated with being female, homeless, binging on methamphetamine, sexual victimization in the past two months, engaging in anal sex 24 or more times in the past two months, and higher sexual compulsivity scores. Effective interventions for this high-risk population should consider gender-focused counseling for sexual abuse, motivational enhancement therapy, social-cognitive skills training, as well as enhanced access and utilization of social services, including drug treatment.

    Sexual communication between sexual partners is an important component in prevention efforts against unintended consequences of sex. The purpose of this study was to describe sexual communication among young adult Latinos. Four semistructured, sex-segregated focus groups were used for this study. Participants (N = 20) were 18-30 years old self-identified Latinos who were in heterosexual and sexually active relationships (more than 3 months). Participants revealed that initial sexual communication with their partners was avoided related to a lack of interest in a partner's sexual history, feeling embarrassed about the topic, or concern for offending one's partner or partner's family. As a result of these beliefs and attitudes, initial sexual communication was nonverbal and focused on sexual pleasure. After the initiation of sexual activity, verbal sexual communication expanded to include sexual history. These findings highlight the importance of attitudes and subjective norms toward verbal sexual communication. Attitudes and subjective norms toward sexual communication in the context of a romantic relationship and how it may impact sexual behavior in the relationship should be further explored.

    Using matched, heterosexual couple data from the Relationship Evaluation Questionnaire (RELATE; n = 326 couples), an adapted common-fate approach was used to examine both common and unique attributes of husbands' and wives' acceptance of pornography and sexual satisfaction as well as husbands' and wives' pornography use. It was expected that spouses' unique as well as shared variance of pornography acceptance would be significantly associated with husbands' and wives' levels of personal pornography use and that these use patterns would be significantly associated with husbands' and wives' unique as well as shared variance of sexual satisfaction. It was also expected that pornography use would significantly mediate the relationship between pornography acceptance and sexual satisfaction. Results indicated that the shared variance of pornography acceptance was positively associated with both spouses' pornography use and that spouses' pornography use was negatively associated with their own sexual satisfaction. Wives' pornography use was found to be positively associated with the couple's shared variance of sexual satisfaction, but pornography use did not significantly mediate the relationship between pornography acceptance and sexual satisfaction. These findings emphasize the complexity of pornography use in couple relationships and the importance of studying pornography acceptance and use as a coupling dynamic within marriages rather than just an individual behavior.

    Sexual partner preferences can be strengthened, weakened or even drastically modified via Pavlovian conditioning. For example, conditioned same-sex partner preference develops in sexually-naïve male rats that undergo same-sex cohabitation under the effects of quinpirole (QNP, D2 agonist). Here, we assessed the effect of prior heterosexual experience on the probability to develop a conditioned same-sex preference. Naïve or Sexually-experienced males received either Saline or QNP and cohabited during 24h with a male partner that bore almond scent on the back as conditioned stimulus. This was repeated every 4days for a total of three trials and resulted in four groups (Saline-naïve, Saline-experienced, QNP-naïve, QNP-experienced). Social and sexual preference were assessed four days after the last conditioning trial in a drug-free test in which experimental males chose between the scented familiar male and a novel sexually receptive female. Results showed that Saline-naïve, Saline-experienced and QNP-experienced displayed a clear preference for the female (opposite-sex). By contrast, only QNP-naïve males displayed a same-sex preference. Accordingly, QNP-experienced males were not affected by the conditioning process and continued to prefer females. We discuss the effects of copulation and D2 agonists on the facilitation and/or disruption of conditioned partner preferences. Copyright © 2017 Elsevier B.V. All rights reserved.

    Following an identical procedure to the one we previously reported (O'Donnell, Lowe, Brotherton, & Bennett, 2014), we examined ratings of sexual attraction to photographs of (the same) adolescent girls (Tanner stages 3-4) labelled as either 14-15 years or 16-17 years old, women, and men. Ratings were made by Bulgarian heterosexual men by pressing buttons on a response box which recorded the ratings made and the time in milliseconds taken to respond. Despite the age of sexual consent in Bulgaria being 14 years, the pattern of findings did not differ from those found in the UK, where the age of consent is 16 years. That is, mean ratings of the sexual attractiveness of the girls labelled as younger were lower than those of the (same) girls labelled as older, and those of the women. In addition, correlations revealed significantly longer responding times when younger girls (and men) were rated as more highly sexually attractive. These associations were reversed in response to the photographs of women. We take these findings to indicate an inhibitory effect arising from generalized sexual norms relating to the inappropriateness of sexual attraction to young girls; the greater the attraction, the higher the inhibition. This second replication of our initial findings suggests a robust effect that may be of benefit in exploration of pedophile or sex offender groups.

    2009-06-01

    Previous research has reported elevated levels of depressive symptoms among methamphetamine users, but little attention has been paid to possible links between family environment and psychological distress. This study examined relationships between family conflict, substance use, and depressive symptoms in a sample of 104 heterosexual methamphetamine users in San Diego, California. Eighty-nine percent of the sample reported conflict with a family member in the past year. Conflict was reported most often with parents and siblings. Sources of conflict included drug use, lifestyle issues, interpersonal and communication issues, and concern for other family members. In regression analyses, being female, being a polydrug user, and facing social and legal stressors were associated with higher levels of family conflict. Multiple regression analyses also revealed a positive association between family conflict and depressive symptoms. Contrary to expectation, methamphetamine dose did not moderate the relationship between family conflict and depressive symptoms. Reducing family conflict may be an important first step toward ameliorating depressive symptoms and creating more supportive environments for methamphetamine users who are in urgent need of effective interventions.

  10. Use of the male condom by heterosexual adolescents and young people: literature review.

    2007-07-01

    This paper is a report of a literature review to explore issues influencing condom use in heterosexual adolescents and young people. Sexually transmitted infections (STIs) are a major international health issue and adolescents and young people are particularly vulnerable. Efforts to address the rapid spread of STIs have largely focused on promoting the use of condoms as a protective 'safer sex' measure. However, use of the male condom is still inconsistent and the incidence of STIs continues to increase. A search of the literature using EBSCO Host databases was undertaken in 2006, with a focus on women, young people, condoms and STIs. Papers published in English from 1992 to 2006 were sought. Only research papers are included in this review. Factors impeding decisions to use protection by young people include lack of knowledge about prevalence of STIs, ambiguity around contraception and safer sex practices, and the difficulty faced by young women in particular in negotiating safer sex. The notion of romantic love confounds the assessment of risk and can render young people, particularly young women, ineffective in negotiating safer sex practices. Adolescents and young adults are particularly vulnerable in relation to STIs. There is a need to ensure that accurate messages are delivered about safer sex and contraception to this very vulnerable group. Furthermore, it is important to recognize that romantic love comprises strong emotions that have a role in decision-making and options for reducing personal-health risk during sexual activity.

  11. Predictors of Parenting Stress in Lesbian, Gay, and Heterosexual Adoptive Parents During Early Parenthood

    Little work has examined parenting stress in adoptive parents, particularly lesbian and gay adoptive parents. The current longitudinal study examined parent-reported child characteristics (measured post-placement) and parent and family characteristics (measured pre-placement) as predictors of post-placement parenting stress and change in parenting stress across three time points during the first 2 years of adoptive parenthood, among 148 couples (50 lesbian, 40 gay, and 58 heterosexual) who were first-time parents. Children in the sample were, on average, 5.61 months (SD = 10.26) when placed, and 2.49 years (SD = .85) at the 2 year post-placement follow-up. Findings revealed that parents who had been placed with older children, and parents who perceived severe emotional/behavioral problems in their children, reported more post-placement stress. In addition, parents who reported fewer depressive symptoms, more love for their partners, and more family and friend support during the pre-placement period, had less post-placement stress. Parenting stress decreased for parents who perceived severe emotional/behavioral problems in their children, while it increased somewhat for those who reported developmental problems in their children. Findings highlight vulnerabilities and resources that may shape adoptive parents’ experiences of stress in early parenthood, and have implications for both researchers and professionals who wish to support adoptive family adjustment.

  12. Singleness, Marriage, and the Construction of Heterosexual Masculinities: Australian Men Teaching English in Japan

    Directory of Open Access Journals (Sweden)

    Roslyn Appleby

    2012-09-01

    Full Text Available This article reports on a study of Australian men and their accounts of living and working in Japan as English language teachers. In this site, recent research has explored Japanese discourses of desire for the West, Western men, and English language learning. These patterns of desire have afforded white Western men a privileged personal and professional status in Japan, and enabled access to employment opportunities as teachers of English language. At the same time, white Western men working as English language teachers face the challenge of negotiating competing discourses that threaten their social status. In particular, their employment in a lowly-regarded profession and a reputation for sexual promiscuity potentially position Western male language teachers as the ‘white trash’ of Asia. My analysis of interview data focuses on the ways in which the men negotiate these discourses, and construct ‘respectable’ Western heterosexual masculinities by mobilising a binary distinction between singleness and marriage. Marriage to a Japanese spouse is presented as a bulwark against alignment with problematic discourses that threaten the status of white masculinity: it is associated with fidelity and maturity, and with integration into Japanese social, linguistic and professional communities. However, the articulation of marital status also reinforces a marginalised position for teachers who do not conform to heteronormative expectations.

    Sexual transmission rates of Chlamydia trachomatis (Ct) cannot be measured directly; however, the study of concordance of Ct infection in sexual partnerships (dyads) can help to illuminate factors influencing Ct transmission. Heterosexual men and women with Ct infection and their sex partners were enrolled and partner-specific coital and behavioral data collected for the prior 30 days. Microbiological data included Ct culture, and nucleic acid amplification testing (NAAT), quantitative Ct polymerase chain reaction, and ompA genotyping. We measured Ct concordance in dyads and factors (correlates) associated with concordance. One hundred twenty-one women and 125 men formed 128 dyads. Overall, 72.9% of male partners of NAAT-positive women and 68.6% of female partners of NAAT-positive men were Ct-infected. Concordance was more common in dyads with culture-positive members (78.6% of male partners, 77% of female partners). Partners of women and men who were NAAT-positive only had lower concordance (33.3%, 46.4%, respectively). Women in concordant dyads had significantly higher median endocervical quantitative Ct polymerase chain reaction values (3,032) compared with CT-infected women in discordant dyads (1013 inclusion forming units DNA equivalents per mL; P model coitus-specific transmission probabilities.

    This paper reports on a feasibility study that examined contingency management among out-of-treatment, heterosexual methamphetamine users and the reduction of drug use and HIV risk. Fifty-eight meth users were recruited through street outreach in Denver from November 2006 through March 2007. The low sample size reflects that this was a pilot study to see if CM is feasible in an out-of-treatment, street-recruited population of meth users. Secondary aims were to examine if reductions and drug use and risk behavior could be found. Subjects were randomly assigned to contingency management (CM) or CM plus strengths-based case management (CM/SBCM), with follow-up at 4 and 8 months. Participants were primarily White (90%), 52% male and averaged 38 years old. Eighty-three percent attended at least one CM session, with 29% attending at least fifteen. All participants reduced meth use significantly at follow-up. Those who attended more sessions submitted more stimulant-free urines than those who attended fewer sessions. Participants assigned to CM/SBCM attended more sessions and earned more vouchers than clients in CM. Similarly, participants reported reduced needle-sharing and sex risk. Findings demonstrate that CM and SBCM may help meth users reduce drug use and HIV risk.

    Whereas gendered sexual scripts are hegemonic at the cultural level, research suggests they may be less so at dyadic and individual levels. Understanding "disjunctures" between sexual scripts at different levels holds promise for illuminating mechanisms through which sexual scripts can change. Through interviews with 44 heterosexually active men and women aged 18 to 25, the ways young people grappled with culture-level scripts for sexuality and relationships were delineated. Findings suggest that, although most participants' culture-level gender scripts for behavior in sexual relationships were congruent with descriptions of traditional masculine and feminine sexuality, there was heterogeneity in how or whether these scripts were incorporated into individual relationships. Specifically, three styles of working with sexual scripts were found: conforming, in which personal gender scripts for sexual behavior overlapped with traditional scripts; exception-finding, in which interviewees accepted culture-level gender scripts as a reality, but created exceptions to gender rules for themselves; and transforming, in which participants either attempted to remake culture-level gender scripts or interpreted their own nontraditional styles as equally normative. Changing sexual scripts can potentially contribute to decreased gender inequity in the sexual realm and to increased opportunities for sexual satisfaction, safety, and well-being, particularly for women, but for men as well.

    Aims We investigated the pharmacokinetics and safety profile of oral ganciclovir coadministered with trimethoprim in HIV-and CMV-seropositive patients. Methods In an open-label, randomized, 3-way crossover study, 12 adult males received oral ganciclovir 1000 mg every 8h, oral trimethoprim 200 mg once daily, or both drugs concomitantly in a sequence of three 7-day treatment periods. Pharmacokinetic parameters were determined and adverse events recorded for each treatment. Results The presence of trimethoprim significantly decreased CLr (12.9%, P = 0.0068) and increased t1/2 (18.1%, P = 0.0378) of ganciclovir. However, these changes are unlikely to be clinically meaningful. There were no statistically significant changes in trimethoprim pharmacokinetic parameters in the presence of ganciclovir, with the exception of a 12.7% increase in Cmin. Ganciclovir was well tolerated when administered alone or in combination with trimethoprim. Conclusions There was no clinically significant pharmacokinetic interaction between oral ganciclovir and trimethoprim when coadministered. PMID:10215748

    The presence of hepatitis B surface antigen (HBsAg) in association with immunoglobulins and complement components within the glomerular basement membranes of adults having chronic active hepatitis has been well documented. In addition, investigators in Poland have demonstrated HBsAg immune complexes in glomeruli of children who did not have clinical evidence of hepatitis. More recently, a single case of childhood membranous glomerulonephritis in an asymptomatic carrier of hepatitis B virus was cited by observers in Canada. Reported here is the deposition of HBsAg immune complexes in the glomerular basement membranes of a 13-year-old black boy who had membranous glomerulopathy but not clinical evidence of hepatitis. This may be the first reported case in the United States of HbsAg-associated membranous glomerulonephritis in a child asymptomatic for hepatitis B virus, and only the second such case in North America. However, unlike previous studies of childhood glomerulopathy in association with hepatitis B virus, this patient is seropositive for both HBsAg and anti-HBs (antibody for hepatitis B surface antigen). Similar "rare" serologic findings were found for the patient's eldest male sib.
