Background: Positive health, dignity, and prevention (PHDP) is Mozambique's strategy to engage clinicians in the delivery of prevention messages to their HIV-positive clients. This national implementation strategy uses provider trainings on offering key messages and focuses on intervening on 9 evidence-based risk reduction areas. We investigated the impact of longitudinal technical assistance (TA) as an addition to this basic training., Methods: We followed 153 healthcare providers in 5 Mozambican provinces over 6 months to evaluate the impact of on-site, observation-based TA on PHDP implementation. Longitudinal multilevel models were estimated to model change in PHDP message delivery over time among individual providers., Results: With each additional TA visit, providers delivered about 1 additional PHDP message ( P < .001); clinicians and nonclinicians started at about the same baseline level, but clinicians improved more quickly ( P = .004). Message delivery varied by practice sector; maternal and child health sectors outperformed other sectors., Conclusion: Longitudinal TA helped reach the programmatic goals of the PHDP program in Mozambique.

As more women become infected with HIV, the issue of childbearing becomes increasingly salient. A more nuanced understanding of women's situations is needed to provide high-quality and relevant services and support. We examined reproductive decision making among 20 women living with HIV through in-depth interviews. These women made decisions within situations of chaos, instability, and trauma, which often limited their ability to make truly informed choices about their lives and childbearing. Despite their HIV, many of the women wanted children, but experienced stigmatization related both to their HIV and to their decisions to have children. This stigmatization came from multiple sources, including health care providers, some of whom encouraged their patients to abort pregnancies because of their HIV. Participants, however, demonstrated resistance to stigmatization, through building supportive communities and developing trusting relationships with HIV providers. These results support the need for specialized HIV care for women of childbearing age., (© The Author(s) 2015.)

This study tests the premise of peer cluster theory as it applies to individual alcohol use, and makes a comparative analysis between its ability to explain alcohol use and marijuana use. Using the results of a 1996 drug and alcohol survey of 1312 Western Kentucky University students, path analysis was used to measure the influence of six of peer cluster theory's psychosocial characteristics on the percentage of the respondent's college friends who use alcohol. All of these variables were then regressed on the respondent's alcohol use. The results of the causal models did show some support for peer cluster theory. The direct effect of the student's association with alcohol-using peers on individual alcohol use was shown to have the strongest direct influence on this outcome variable. However, a few limitations of this theoretical perspective were identified. The causal model for alcohol use showed that the indirect influence of two of these psychosocial characteristics (parental attitudes on alcohol use and success in school) was weaker than their direct influence on individual alcohol use. And, the comparative analysis showed that peer cluster theory is better suited to explain the use of marijuana than the use of alcohol.

The medical records of 227 children ages 1 to 19 years referred to the Lyme disease pediatric clinic over a 32-month period since May 1990 were reviewed. Clinico-serologic criteria for a positive diagnosis were applied. One hundred thirty-eight of 227 referred children did not fulfill those criteria and became the study population. Four subsets of patients emerged: (1) 54 patients with predominantly subjective symptoms; (2) 52 patients with objective evidence for an alternative diagnosis; (3) eight patients who had documented infection in the past and continued with symptoms after antibiotic treatment; and (4) 24 patients with a history of tick attachment or prenatal/family history of Lyme disease. Serologic testing data from commercial laboratories were available for the 54 children from the "predominantly subjective" group; 50% were negative, and 50% were borderline or positive. Ninety-two percent of these patients were negative at retesting by our enzyme-linked immunosorbent assay (ELISA) and 100% were negative by Western blot. Fifty-seven percent of these patients had received treatment prior to our evaluation. Children residing in an endemic area who present with vague symptoms are being diagnosed with and treated for Lyme disease without clinical or serologic documentation. In addition, fear in the lay community may be inducing doctors to diagnose Lyme disease in patients with symptoms that may be suggestive of an alternative diagnosis.

To assess the beliefs and practice habits regarding Lyme disease among practitioners, questionnaires were sent to physicians in a seven-county Lyme-endemic region. One hundred twenty-four evaluable responses were returned from 53 family physicians, 39 pediatricians, 27 internists, and five subspecialists who diagnosed three to four cases of Lyme disease per year, on average. The majority presented with erythema migrans (EM) or other early symptoms, although arthritis was the presenting sign in 16%. The enzyme-linked immunosorbent assay (ELISA) was the most frequently ordered diagnostic test, but 45% of respondents did not specify which test when ordering Lyme serology. The majority would use amoxicillin or doxycycline to treat EM in children or adults, respectively. Nearly all would use ceftriaxone for meningitis, and half would use it to treat Lyme arthritis or Bell's palsy. Physicians differed markedly in the duration of therapy they would prescribe. Eighty-three percent would treat a patient for possible Lyme disease with antibiotics (many intravenously), even in the absence of EM or positive serology. Thirty-five percent of practitioners prescribed antibiotics for deer-tick bites. Our survey documents significant variation in approaches to Lyme disease among primary-care physicians and suggests the need for well-designed clinical trials, continuing basic research, and physician education.
