Evaluation of HIV counseling and testing in ANC settings and adherence to short course antiretroviral prophylaxis for PMTCT in Francistown, Botswana

Worldwide, it is estimated that two million children are infected with HIV (USAID 2005). The vast majority of these infections are the result of mother-to-child transmission (MTCT) of the virus during pregnancy, labor, or breastfeeding. However, there are effective methods for prevention of mother-to-child transmission (PMTCT). Botswana is one of the first countries in the developing world with a national PMTCT program that uses an efficacious and complex regimen to reduce vertical transmission. At the time of this evaluation (August - December 2005), the standard of care for prevention of MTCT of HIV in Botswana included three-drug antiretroviral therapy for HIV-infected women with a CD4 count of 200 (300 mg AZT in the morning and 300 mg AZT in the evening); four weeks of AZT for their infants; single-dose maternal and infant nevirapine (NVP); and 12 months of free infant formula. Botswana's PMTCT program also provided routine HIV testing for all pregnant women during antenatal care (ANC) to identify HIV-positive women for prophylaxis or treatment. While programs often report the number of individuals beginning AZT and receiving nevirapine for PMTCT, effectiveness is dependent on the level of adherence of individuals to these regimens. To describe adherence of pregnant women to the current PMTCT regimen, the Horizons Program of the Population Council, in collaboration with the Centers for Disease Control and Prevention (CDC) and Premiere Personnel in Botswana, conducted an evaluation to describe HIV-related services provided to women during their pregnancies, document the content of post-test counseling sessions for HIV-positive pregnant women, whether HIV-positive women remembered what had been discussed, the extent of AZT adherence based on self-reports, and the operational successes and barriers to adherence to AZT for PMTCT

The Horizons Program of the Population Council, in collaboration with the Centers for Disease Control and Prevention (CDC) and Premiere Personnel in Botswana, conducted an evaluation to describe the adherence of pregnant women to the current PMTCT regimen. The report recommends standardizing post-test counseling content through the use of job aids and adapting existing WHO materials, assessing each client’s understanding of essential HIV information, encouraging provision of at least two post-test counseling sessions for each woman and inviting partners and other family members, and improving the distribution of AZT as well as information about community resources

Training youth caregivers to provide HIV education and support to orphans and vulnerable children in South Africa

In KwaZulu Natal, South Africa, in Durban’s peri-urban community of Valley of 1000 Hills, Horizons partnered with Valley Trust to implement and evaluate a program to provide education and support to orphans and vulnerable children. The study utilized a pre-post test design to assess the feasibility and impact of building the capacity of youth aged 18–24 years to provide HIV education and support to in-school orphans and vulnerable children in their communities. The Valley Trust Youth Caregiver Program trained older youth to provide HIV education, homework assistance, and psychosocial support to orphans and vulnerable children aged 11–15 years. The program aimed to increase HIV-related knowledge, improve HIV communication skills, and decrease stigmatizing attitudes. As noted in this brief, trained volunteer youth caregivers operating in a school-based setting can reach children who are orphaned and rendered vulnerable by their household and community circumstances. The education and support provided likely contribute to improvements in HIV-related knowledge, attitudes, and communication among program participants, given that the gains they made were often greater than those of nonparticipants

The Kitty Microbiome Project: Defining the Healthy Fecal “Core Microbiome” in Pet Domestic Cats

Here, we present a taxonomically defined fecal microbiome dataset for healthy domestic cats (Felis catus) fed a range of commercial diets. We used this healthy reference dataset to explore how age, diet, and living environment correlate with fecal microbiome composition. Thirty core bacterial genera were identified. Prevotella, Bacteroides, Collinsella, Blautia, and Megasphaera were the most abundant, and Bacteroides, Blautia, Lachnoclostridium, Sutterella, and Ruminococcus gnavus were the most prevalent. While community composition remained relatively stable across different age classes, the number of core taxa present decreased significantly with age. Fecal microbiome composition varied with host diet type. Cats fed kibble had a slightly, but significantly greater number of core taxa compared to cats not fed any kibble. The core microbiomes of cats fed some raw food contained taxa not as highly prevalent or abundant as cats fed diets that included kibble. Living environment also had a large effect on fecal microbiome composition. Cats living in homes differed significantly from those in shelters and had a greater portion of their microbiomes represented by core taxa. Collectively our work reinforces the findings that age, diet, and living environment are important factors to consider when defining a core microbiome in a population
