Abstract

Malawi launched Option B+, a program for all pregnant or breastfeeding HIV-positive women to begin lifelong combination antiretroviral therapy (cART), in July 2011. This study characterises a portion of the continuum of care within an antenatal setting in Lilongwe. Women testing HIV-positive and having a cART initiation record at Bwaila Antenatal Clinic from July 2013 to January 2014 were included. Using logistic regression models, we analysed relationships between maternal characteristics and return for infant testing. Among 490 HIV-positive women with a cART initiation record, 360 (73%) were retained at three months. Of these, 203 (56%) were adherent. Records of infant testing were located for 204 women (42%). Women who were not retained were less likely to have an early infant diagnosis record (aOR = 0.20; 95% CI: 0.10, 0.41). Among the women retained, there was a non-significant association between maternal adherence and infant testing (OR = 1.35; 95% CI: 0.89, 2.06). Women lost at earlier continuum stages, who are at higher risk for mother-to-child-transmission, were less likely to bring infants for testing. Even with a test-and-treat program, many women did not remain in care or bring their infant for testing. Facilitating strategies to improve these measures remains an important unmet need.

39. Technical Note: Synthesis of isoprene atmospheric oxidation products: isomeric epoxydiols and the rearrangement products cis- and trans-3-methyl-3,4-dihydroxytetrahydrofuran

Author

Zhang, H., Surratt, J. D., Zhang, Z., Ball, L. M., Gold, A., and Lin, Y. H.

Abstract

Isoprene epoxydiol (IEPOX) isomers are key gas-phase intermediates of isoprene atmospheric oxidation. Secondary organic aerosols derived from such intermediates have important impacts on air quality and health. We report here convergent and unambiguous pathways developed for the synthesis of isomeric IEPOX species and the rearrangement products cis- and trans-3-methyl-3,4-dihydroxytetrahydrofuran in good yield. The availability of such compounds is necessary to expedite research on isoprene atmospheric oxidation mechanisms and subsequent aerosol formation as well as the toxicological properties of the aerosols.

43. Reconciling animal and human data in a cancer risk assessment of acrylonitrile

Author

Hertz-Picciotto, I., Todd, L., Ball, L. M., and Schulz, M. R.

Abstract

OBJECTIVES: Bioassays of rats exposed to acrylonitrile have consistently detected an elevated incidence of central nervous system (CNS) cancer. In contrast, epidemiologic studies have not found a statistically stable increase in CNS cancer mortality. The purpose of this paper is to examine whether or not CNS cancers predicted from the most appropriate inhalation bioassay in rats are consistent with CNS cancers observed in 3 recent, large epidemiologic studies. METHODS: A linearized multistage model was fit to dose-response data from a rat inhalation bioassay to estimate carcinogenic potency. This potency was applied to epidemiologic studies of acrylonitrile-exposed workers. After adjustment for less than complete lifetime follow-up in the epidemiologic studies, consistency was examined between CNS cancers predicted by the model fit to the animal data for the exposure levels and sample sizes of the epidemiologicy studies and the CNS cancers observed in the epidemiologic studies. RESULTS: The model predicted totals of 17.7, 3.6, and 7.6 CNS cancer deaths for the studies. These predictions were not far from the observed CNS cancer deaths (12, 6, and 6) and were well within their 95% confidence intervals of 6.9-22.3, 2.2-13.1, and 2.2-13.1, respectively. CONCLUSIONS: The CNS cancer potency estimated from the best available inhalation bioassay was consistent with the observed deaths in the epidemiologic studies as long as continuous lifetime exposure was chosen as the exposure metric. The lack of observed excess in CNS cancer among the studied workers may have been due to low exposures, insufficient follow-up times, or both.
