Dissemination and implementation of an evidence-based voluntary medical male circumcision program
Despite compelling evidence linking voluntary medical male circumcision (VMMC) with 60–70% HIV risk reduction in sub-Saharan Africa, Zambian men have been especially reluctant to undergo VMMC. The Government of Zambia set targets for VMMC uptake and promoted community-level interventions. Spear & Shield (S&S) is an innovative, evidence-based, service program promoting VMMC uptake while ensuring both VMMC supply and demand. This study assessed the…
Factors influencing neonatal male circumcision uptake among expecting couples in Zambia
Male circumcision is a protective HIV prevention strategy. However, uncircumcised Zambian men are reluctant to undergo voluntary medical male circumcision (VMMC). Tailored interventions are necessary to stimulate the uptake of early infant male circumcision (EIMC) and VMMC in Zambia. This feasibility study presents the formative process of utilising the PRECEDE framework in the development of a family-centred EIMC/VMMC intervention, Like Father L…
Early Infant Male Circumcision Decisions in Zambia
Public health initiatives in Zambia encourage the uptake of early infant male circumcision (EIMC) as an HIV prevention strategy. This study assessed EIMC parental decision-making during perinatal care in Lusaka, Zambia, focusing on the influence of sociodemographic factors, family, and friends. A longitudinal pilot perinatal intervention, Like Father Like Son (LFLS), was implemented among 300 couples attending antenatal clinics in four urban comm…
Zambian Parents’ Perspectives on Early-Infant Versus Early-Adolescent Male Circumcision
Psychological and physical intimate partner violence and sexual risk behavior among South African couples
This study aimed to examine intimate partner violence (IPV) as it relates to both partners’ perceptions of IPV and sexual behaviors, considering how their IPV might be interdependent within the relationship dynamics. The sample consisted of 713 female–male dyads in which women were pregnant and living with HIV in rural South Africa. Using an actor-partner interdependence model (APIM), we examined the interdependent influence of psychological and …
The contribution of syndemic conditions to cardiovascular disease risk
The syndemic conditions of low education, childhood maltreatment, depression, HIV, alcohol and cocaine use, and obesity have been established as independent risk factors for cardiovascular risk, but research examining the association between syndemic conditions and cardiovascular risk in high-risk populations is lacking. A total of N = 503 participants underwent an ultrasound of the carotid artery to assess for atherosclerotic plaque. Participant…
Blood Pressure, Depression, and Suicidal Ideation Among Pregnant Women with HIV
Maternal and infant antiretroviral therapy adherence among women living with HIV in rural South Africa
‘Mother-to-child transmission of HIV’ can occur during the period of pregnancy, childbirth, or breastfeeding. ‘Prevention of mother-to-child transmission of HIV’ (PMTCT) in Mpumalanga Province, South Africa, is especially vital as the prevalence of HIV is 28.2% in women aged 15–49. PMTCT interventions resulted in a drop of MTCT rates in Mpumalanga from ∼2% in 2015 to 1.3% in 2016. This randomised controlled trial in Mpumalanga examined the potent…
HIV and carotid atherosclerosis
Cardiovascular disease (CVD) is the leading cause of death in the US and is a significant contributor to morbidity and mortality for people living with HIV (PLWH). This study examined the association between HIV infection, cocaine usage, and inflammatory markers, and their combined association with carotid atherosclerosis among young and middle-aged adults with HIV. Participants (N = 494) were enrolled based on HIV status and cocaine use. Blood p…
Development, implementation and dissemination
Over a million people are living with HIV in Zambia, representing ∼13% of the country’s population. To increase HIV prevention communication, a community-based communication training program, the Parent–Child and Couples Communication Workshop, was developed from pilot data and culturally tailored for dissemination in Zambia. Workshop trainees (N = 195) were 18 years of age or more and community educators and counselors in the Copperbelt and Sout…
The association of HIV and cocaine use to cigarette smoking in the context of depression and perceived stress
Mental well-being can contribute to cigarette smoking and negatively impact disease progression among people living with HIV (PLWH). This study examined potential associations between cocaine use (COC), depression, and HIV status in predicting cigarette smoking; hypothesizing that depression would be highest in cocaine users and predict cigarette smoking. An exploratory analysis including stress was also examined as a potential predictor of cigar…

Sexual risk behavior among HIV-infected women in South Africa at 12-months postpartum
The postnatal period is a time of increased susceptibility to HIV infection and superinfection for postpartum women, sexual partners, and infants. This study examined the effect of a prevention to mother-to-child transmission of HIV intervention compared to standard care, and factors associated with unprotected last sex and inconsistent condom use at 12-months postpartum. Participants were N = 1399 HIV-infected women 6–30 weeks pregnant (M = 18 w…
Suicidal Ideation Among Adults Re-engaging in HIV Care in Argentina
HIV knowledge and risk among Zambian adolescent and younger adolescent girls
In sub-Saharan Africa, young women are at the highest risk of HIV infection. Comprehensive sexuality education (CSE) and open parent-child communication about sex have been shown mitigate risky sexual practices associated with HIV. This study aimed to identify sources of HIV prevention knowledge among young women aged 10-14 years and community-based strategies to enhance HIV prevention in Zambia. Focus group discussions were conducted with 114 yo…
Suicidality among nonadherent patients living with HIV in Buenos Aires, Argentina
Of those in the general population hospitalized for suicidal ideation and suicide attempts in Argentina, many reattempt suicide and are readmitted. However, few studies in Argentina have examined suicidal ideation and suicide-related behaviors among people living with HIV (PLHIV) and none have examined these factors among nonadherent PLHIV, though the prevalence of suicidal ideation in this group may be higher than in the general population and a…
Prevalence and Factors Associated with Fixed-Dose Combination Antiretroviral Drugs Adherence among HIV-Positive Pregnant Women on Option B Treatment in Mpumalanga Province, South Africa
The possibility for all babies to be born and remain HIV-negative for the first year of life is achievable in South Africa. HIV-positive mothers' adherence to their antiretroviral medication is one of the crucial factors to achieve this target. Cross-sectional data were collected at 12 community health centres, over 12 months (2014-2015), from 673 HIV-positive women, less than 6 months pregnant, attending antenatal care, and on Option B treatment…
Sexual risk behaviour among HIV-infected women in the first twelve months after delivery in South Africa
This study aimed to assess sexual risk behaviour and its social correlates in HIV-infected women living in rural South Africa at six and twelve months post-partum. Participants were 699 HIV-positive women recruited prenatally by systematic sampling from twelve community health centres in Mpumalanga province, South Africa (mean age = 28.4 years, SD = 5.7; married =41.1%; serodiscordant or unknown partner status = 74.9%). They self-reported on thei…

Decreased Depression Up to One Year Following CBSM+ Intervention in Depressed Women with Aids
This prospective multisite Phase III clinical trial (Miami, New York, New Jersey) investigated the long-term (one year) effects of a 10-week group cognitive-behavioral stress management/expressive supportive therapy (CBSM+) intervention on disadvantaged minority women living with AIDS. The CBSM+ intervention consisted of 10-weekly group session of stress management, cognitive-behavioral skill training, relaxation techniques and expressive-support…
The Achilles' heel of prevention to mother-to-child transmission of HIV
The Joint United Nations Programme on HIV and AIDS proposed to reduce the vertical transmission of HIV from ∼72,200 to ∼8300 newly infected children by 2015 in South Africa (SA). However, cultural, infrastructural, and socio-economic barriers hinder the implementation of the prevention of mother-to-child transmission (PMTCT) protocol, and research on potential solutions to address these barriers in rural areas is particularly limited. This study …
International Business Negotiation in a Globalizing World
Research on international business negotiation has been underway for 35 years. It has developed within two major paradigms: the macro-strategic, which focuses on organizational wholes, and the micro-behavioral, which focuses on individuals. The former further divides into business-government relations and interfirm relationship streams, while the latter branches into comparative and intercultural studies. While this article summarizes these bodie…

Psychological and Physical Intimate Partner Violence and Maternal Depressive Symptoms during the Pre- and Post-Partum Period among Women Living with HIV in Rural South Africa
HIV knowledge, disclosure and sexual risk among pregnant women and their partners in rural South Africa
Partner involvement has been deemed fundamental for the prevention of mother-to-child transmission (PMTCT) of HIV, although it remains difficult to achieve. This study aimed to explore the attitudes and behaviours of pregnant women and their partners who participated in a behavioural risk reduction intervention in six community health centres in the Mpumalanga province of South Africa. Qualitative methods only were used in this study. Women and t…
Efficacy of a lay health worker led group antiretroviral medication adherence training among non-adherent HIV-positive patients in KwaZulu-Natal, South Africa
There is a lack of theory-based randomized controlled trials to examine the effect of antiretroviral adherence in sub-Saharan Africa. We assessed the effectiveness of a lay health worker lead structured group intervention to improve adherence to antiretroviral therapy (ART) in a cohort of HIV-infected adults. This two-arm randomized controlled trial was undertaken at an HIV clinic in a district hospital in South Africa. A total of 152 adult patie…
Sexual risk reduction among Zambian couples
Zambia has over 1 million HIV infections nationwide and an urban prevalence rate of 23%. This study compared the impact of male involvement in multiple and single session risk reduction interventions among inconsistent condom users in Zambia and the role of serostatus among HIV-seropositive and serodiscordant couples. Couples (N=392) were randomised into intervention arms. Among inconsistent condom users at baseline (N=83), condom use increased i…

The impact of improved self-efficacy on HIV viral load and distress in culturally diverse women living with Aids
The purpose of the present study was to determine whether changes in self-efficacy over time would be related to changes in disease progression markers (CD4, viral load) in a sample of women with AIDS. A self-efficacy measure was developed and two sub-scales emerged via factor analysis of 391 HIV-positive women: AIDS Self-efficacy and Cognitive Behavioral Skills Self-efficacy. Subsequently, the sub-scales and an additional adherence self-efficacy…

The effects of low literacy and cognitive impairment on medication adherence in HIV-positive injecting drug users
Low literacy and cognitive impairment have each been separately identified as risks for non-adherence in HIV infection. However, no studies to date have evaluated these skill deficits in combination. We therefore characterized the nature of literacy and cognitive skills in a sample of HIV-positive injecting drug users and assessed their combined effects on adherence. A community-recruited sample of 57 HIV-positive injecting drug users completed t…
Sexual risk reduction among Zambian couples

Self-efficacy and distress in women with Aids
Though African American and Hispanic women accounted for 14% of the female population in the USA, they represented 66% of the total HIV/AIDS diagnoses among women in 2007. Among men living with HIV, increased coping self-efficacy (SE) following a cognitive behavioral intervention has been related to decreased distress, anxiety, anger, and confusion, but comparable studies had not been carried out with HIV+ women. The purpose of this study was to …
Mental health in HIV seronegative and seropositive IDUs in South Florida
About one-third of HIV-infected people in the USA have a history of injection-drug use. Injecting drugs are a primary vector for HIV transmission. Drug and alcohol use are significant contributors to sexual transmission of the virus. In South Florida, urban injection-drug users (IDUs) represent a substantial population at risk for infection. Substance use management in this group is critical. As part of a larger study of at-risk populations in So…

Quality of relationship and sexual risk behaviors among HIV couples in Lusaka, Zambia
Relationship quality and partner dynamics provide important insights into understanding sexual behavior within HIV sero-positive and sero-discordant couples. Individuals in long-term partnerships may be vulnerable to HIV/sexually transmitted infections (STI) within their relationships due to misperceptions of their partners risk behaviors and potential concurrent (e.g., extramarital, nonprimary) sexual partnerships. This study sought to examine r…
Reducing the risk of HIV infection during pregnancy among South African women
Mpumalanga Province, South Africa has one of the highest HIV/AIDS diagnosis rates among pregnant women (~29.4%). This study sought to enhance male involvement in pregnancy to increase HIV disclosure, sexual communication, HIV knowledge and reduce unprotected sex. Participants attending Antenatal Clinics (ANC) completed HIV counseling and testing and were enrolled with male partners (n=239 couples, 478 individuals). Twelve ANCs were randomly assig…
