Congenital malformations in infants exposed to antiepileptic medications in utero at Boston Medical Center from 2003 to 2010

ObjectiveThe aim of this study was to determine the frequency of association of major congenital malformations in pregnancy in women exposed to antiepileptic drugs (AEDs) in an inner city population.BackgroundApproximately 0.3–0.5% of all pregnancies involve women with epilepsy. The risk of congenital malformations associated with AED therapy has been well documented, ranging from 2 to 10% as compared to a rate of 3% in the general population. However, the risk of these occurring in a higher risk population, such as an inner city tertiary care center, with multiple comorbidities is not as well known.Design/methodsUsing the Boston Medical Center Database between the years 2003 and 2010, a list of all infants born with major congenital malformations (MCMs) to mothers on AEDs was compiled. Major congenital malformations were defined as cleft lip and/or palate, ventricular or atrial septal defect, other cardiac malformations, and urogenital defects. During pregnancy, AED exposure including serum levels, other medication exposures, breakthrough seizure frequency, positive toxicology tests, and other maternal comorbidities were also analyzed.ResultsOf 17,246 live births between 2003 and 2010, 330 of those births demonstrated a MCM (malformation rate of 1.91%). Of those births, 64 mothers had epilepsy and were exposed to AED therapy during pregnancy, accounting for 0.37% of all births during this time period. Overall, three pregnancies in women with epilepsy resulted in a baby with a MCM, accounting for a 4.7% malformation rate in this patient population. In mothers on AEDs for other indications, the MCM rate was slightly higher, 5.0%, and in women on benzodiazepine monotherapy during pregnancy, the rate was quite high, 10.6%.     

Neighborhood disadvantage,individual-level socioeconomic position and physical function: A cross-sectional multilevel analysis

IntroductionUnderstanding associations between physical function and neighborhood disadvantage may provide insights into which interventions might best contribute to reducing socioeconomic inequalities in health. This study examines associations between neighborhood-disadvantage, individual-level socioeconomic position (SEP) and physical function from a multilevel perspective.MethodsData were obtained from the HABITAT multilevel longitudinal (2007-13) study of middle-aged adults, using data from the fourth wave (2013). This investigation included 6004 residents (age 46–71 years) of 535 neighborhoods in Brisbane, Australia. Physical function was measured using the PF-10 (0–100), with higher scores indicating better function. The data were analyzed using multilevel linear regression and were extended to test for cross-level interactions by including interaction terms for different combinations of SEP (education, occupation, household income) and neighborhood disadvantage on physical function.ResultsResidents of the most disadvantaged neighborhoods reported significantly lower physical function (men: β − 11.36 95% CI − 13.74, − 8.99; women: β − 11.41 95% CI − 13.60, − 9.22). These associations remained after adjustment for individual-level SEP. Individuals with no post-school education, those permanently unable to work, and members of the lowest household income had significantly poorer physical function. Cross-level interactions suggested that the relationship between household income and physical function is different across levels of neighborhood disadvantage for men; and for education and occupation for women.ConclusionLiving in a disadvantaged neighborhood was negatively associated with physical function after adjustment for individual-level SEP. These results may assist in the development of policy-relevant targeted interventions to delay the rate of physical function decline at a community-level.     

Feasibility and Effectiveness of Telelactation Among Rural Breastfeeding Women

ObjectiveTo evaluate the feasibility and impact of telelactation via personal electronic devices on breastfeeding duration and exclusivity among rural women.MethodsThe Tele-MILC trial, a pragmatic, parallel design trial, recruited 203 women during their postpartum hospitalization in a critical access hospital in Pennsylvania and randomized them to receive telelactation (n = 102) or usual care (n = 101). We used intent-to-treat (ITT) and instrumental variable (IV) approaches to analyze study data for the 187 participants who completed follow-up. The primary outcomes were any breastfeeding and exclusive breastfeeding at 12 weeks postpartum.ResultsAmong participants in the telelactation arm, 50% (47/94) reported participating in video calls. At 12 weeks, 71% of participants in the telelactation arm versus 68% of control participants were breastfeeding in the ITT model (3% difference, P = .73), whereas 73% of participants in the telelactation arm versus 68% of control participants were breastfeeding in the IV model (5% difference, P = .74). Among participants who were still breastfeeding at 12 weeks, 51% participants in the telelactation arm were breastfeeding exclusively versus 46% of control participants in the ITT model (5% difference, P = .47), whereas 56% of participants in the telelactation arm were breastfeeding exclusively versus 45% of control participants in the IV model (11% difference, P = .48). In all models, participants in the telelactation arm were breastfeeding at higher rates; however, differences were not statistically significant.ConclusionsThis trial demonstrated that telelactation can be implemented with a rural underserved population. Though this trial was not powered to detect differences in breastfeeding duration and exclusivity, and none were observed, telelactation remains a promising approach for further investigation.
