Abstract The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides nutritional support for pregnant and postpartum women and young children. The typical food package provided to recipient families was revised in October 2009 to include more whole grains, fruits, vegetables, and low-fat milk. Little is known about whether these revisions improved nutrition among women during this critical period of the life course. We conducted a quasiexperimental difference-in-differences analysis, comparing WIC recipients (“treatment” group) before and after the WIC policy change, while accounting for temporal trends among nonrecipients (“control” group). We examined nutritional outcomes among a cohort of 1,454 women recruited during pregnancy in 2006–2011 in Memphis and surrounding Shelby County, Tennessee. We found improvements in several measures of dietary quality and nutrient intake during pregnancy, although these did not persist into the postpartum period. Results were robust to numerous sensitivity analyses. At a time when federal WIC funding is threatened, this study provides some of the first evidence of the benefits of recent WIC revisions among low-income women.

ABSTRACT A comparison of the range of urinary excretion of 20 elements (Ag, As, Au, Br, Ce, Cd, Cs, Cu, Fe, Hg, La, Mg, Mo, Rb, Sb, Sc, Se, Sm, W, Zn) in healthy subjects as well as in patients with primary hyperparathyroidism before and after operation was performed by means of a recently developed ion-exchange technique following neutron activation analysis. The urinary levels of the 20 trace elements showed no distinct differences when the controls were compared with the untreated cases of hyperparathyroidism. Small differences in the urinary excretion of certain trace elements in patients with hyperparathyroidism before and after operation were, however, revealed. The biological significance of these findings is discussed.

AbstractNew York City hospitalization rates were analyzed to investigate whether tuberculosis (TB) hospitalizations declined after implementation of directly observed therapy QOOT) for TB. TB hospitalization rates mirrored incidence rates in pattern but not in magnitude. Rates have declined significantly following widespread implementation of DOT in 1993.

OBJECTIVES: Previous research revealed declines in survivorship in London before the Black Death (c. 1346-1353), and improvements in survivorship following the epidemic. These trends indicate that there were declines in general levels of health before the Black Death and improvements thereof afterwards. This study expands on previous research by examining whether changes in survivorship were consistent between the sexes, and how patterns of developmental stress markers changed before and after the Black Death.MATERIALS AND METHODS: This study uses samples from London cemeteries dated to one of three periods: Early Pre-Black Death (1000-1200 AD, n = 255), Late Pre-Black Death (1200-1250 AD, n = 247), or Post-Black Death (1350-1540 AD n = 329). Temporal trends in survivorship are assessed via Kaplan-Meier survival analysis, and trends in tibial length (as a proxy for stature) and linear enamel hypoplasia (LEH) are assessed using t-tests and Chi-square tests, respectively.RESULTS: Survivorship for both sexes decreased before the Black Death and increased afterwards. For males, LEH frequencies increased and stature decreased before the epidemic, and LEH declined and stature increased after the Black Death. For females, the only significant change with respect to developmental stress markers was a decrease in stature after the Black Death.CONCLUSIONS: These results might reflect variation between the sexes in sensitivity to stressors, the effects of nutrition on pubertal timing, disproportionate access to dietary resources for males in the aftermath of the Black Death, the disproportionate deaths of frail individuals during the epidemic, or some combination of these factors.
