RESUMEN
Subarachnoid neurocysticercosis (SANCC) is a severe and progressive brain infection with Taenia solium. We performed a pilot study of noninvasive screening for SANCC in two endemic villages in northern Peru using a urine antigen screen followed by brain magnetic resonance imaging for participants with elevated levels of antigen. Among the 978 participants screened, we identified eight individuals with SANCC, many of whom were asymptomatic. This represents a minimum prevalence of 0.8% of SANCC, a level higher than expected based on prior studies, and a positive predictive value of 62% for our novel urine screening test. Future studies should confirm whether early detection and management improve clinical outcomes.

UNLABELLED: Objectives Mexican-origin children living along the US-Mexico border in colonias communities are medically underserved, at great risk for obesity-related diseases, and rarely meet physical activity guidelines. This study examined the roles of parental social support and social norms for physical activity among these children. METHODS: Promotora-researchers conducted one-on-one interview-administered surveys with 99 Mexican-origin mother-child dyads (n=198). Survey items examined perceptions of familial social support and norms relating to physical activity. RESULTS: Parental social support for physical activity received by children was low, and gender differences were detected. Discrepancies between mother and child perceptions were also detected. CONCLUSIONS: High rates of overweight and obesity and low familial social support indicate a need for improved parental social support to increase physical activity levels and combat obesity among underserved Mexican-origin children residing in Texas border colonias.
