How Treatment Partners Help: Social Analysis of an African Adherence Support Intervention

Treatment partnering is an adherence intervention developed in sub-Saharan Africa. This paper describes the additional social functions that treatment partners serve and shows how these functions contribute to health and survival for patients with HIV/AIDS. Ninety-eight minimally structured interviews were conducted with twenty pairs of adult HIV/AIDS patients (N = 20) and treatment partners (N = 20) treated at a public HIV-care setting in Tanzania. Four social functions were identified using inductive, category construction and interpretive methods of analysis: (1) encouraging disclosure; (2) combating stigma; (3) restoring hope; and (4) reducing social difference. These functions work to restore social connections and reverse the isolating effects of HIV/AIDS, strengthening access to essential community safety nets. Besides encouraging ARV adherence, treatment partners contribute to the social health of patients. Social health as well as HIV treatment success is essential to survival for persons living with HIV/AIDS in sub-Saharan Africa

Strategies to prevent HIV transmission among heterosexual African-American men

BACKGROUND: As part of qualitative research for developing a culturally sensitive and developmentally appropriate videotape-based HIV prevention intervention for heterosexual African- American men, six focus groups were conducted with thirty African-American men to determine their perceptions of AIDS as a threat to the African-American community, characteristics of past situations that have placed African Americans at risk for HIV infection, their personal high risk behaviors, and suggestions on how HIV intervention videotapes could be produced to achieve maximum levels of interest among African-American men in HIV training programs. METHODS: The groups took place at a low-income housing project in Houston, Texas, a major epicenter for HIV/AIDS. Each group was audiotaped, transcribed, and analyzed using theme and domain analysis. RESULTS: The results revealed that low-income African-American men perceive HIV/AIDS as a threat to their community and they have placed themselves at risk of HIV infection based on unsafe sex practices, substance abuse, and lack of knowledge. They also cite lack of income to purchase condoms as a barrier to safe sex practice. They believe that HIV training programs should address these risk factors and that videotapes developed for prevention should offer a sensationalized look at the effects of HIV/AIDS on affected persons. They further believe that programs should be held in African-American communities and should include condoms to facilitate reduction of risk behaviors. CONCLUSIONS: The results indicate that the respondents taking part in this study believe that HIV and AIDS are continued threats to the African-American community because of sexual risk taking behavior, that is, failure to use condoms. Further, African-American men are having sex without condoms when having sex with women often when they are under the influence of alcohol or other mind-altering substances and they are having sex with men while incarcerated and become infected and once released resume unprotected sexual relations with women. According to the men, substance abuse is an important part of the problem of HIV in the African-American community. This is in keeping with research that shows that drug use, especially crack cocaine, is linked to sexual risk taking among African Americans and to increased likelihood of becoming infected with other sexually transmitted diseases (STDs) including HIV. Thus, interventions for men should address condom use, condom availability, skills for using condoms, eroticizing condoms and substance abuse prevention. Men in the present study also strongly recommended that HIV/AIDS videotaped messages should include footage of the sensational effects of the disease

Silencing SERCA1b in a few fibers stimulates growth in the entire regenerating soleus muscle

The neonatal isoform of the sarcoplasmic/endoplasmic reticulum Ca2+ ATPase 1 (SERCA1b) is a dominant Ca2+ pump in the young Wbers of regenerating muscle. In vivo transfection of about 1% of the Wbers with SERCA1b RNAi plasmid resulted in no apparent change in the transfected Wbers, but enhanced the increase of fresh weight and Wber size in the whole regenerating rat soleus muscle, until the normal size was reached. Co-transfection of calcineurin inhibitor cain/cabin-1 with SERCA1b RNAi was suYcient to cut down the widespread growth stimulation, but the subsequent transfection of cain into the SERCA1b RNAi transfected muscle did not inhibit muscle growth. The SERCA1b RNAi preferably upregulated the expression of the NFAT reporter lacZ compared to controls when co-transfected into the Wbers. Notably, perimuscular injection of interleukin-4 (IL-4) antibody but not that of an unrelevant antibody completely abolished the growth-promoting eVect of SERCA1b RNAi. This indicates that silencing SERCA1b in a few Wbers stimulates the calcineurin- NFAT-IL-4 pathway and Wber growth in the whole regenerating soleus. These results suggest the presence of an autocrine–paracrine coordination of growing muscle Wbers, and put forward a new method to stimulate skeletal muscle regeneration
