Trachoma, the world's leading infectious cause of blindness: The remaining gap in care and access to basic handwashing facilities.

PURPOSE: Trachoma, the world's leading infectious cause of blindness, has been targeted by the WHO for elimination through the SAFE strategy: surgery, antibiotics, facial cleanliness, and environmental improvement. Although significant progress has been made, there remains a gap in care. This project studied the association of geographical distribution of the remaining need for trachoma intervention and its association with access to basic handwashing facilities at home, as an indicator of water/sanitation infrastructure. We hypothesized that poor water sanitation would correspond to areas where trachoma intervention is still required. DESIGN: Retrospective analysis using the WHO Global Health Observatory. Spatial, correlation, and simple and multivariable regression analyses were used. METHODS: Using data from the WHO Global Health Observatory, a total of 194 countries were analyzed. Two choropleth maps were created, with inset maps focused on the South Pacific region, where the top 5 countries with the greatest population proportion requiring trachoma intervention are located. RESULTS: Correlations and the simple regression model of total population with access to handwashing facilities as the only risk factor were insignificant. However, the multivariable regression models with access to handwashing facilities (total, urban, and rural) and population density as risk factors for trachoma intervention were significant. CONCLUSION: Poor water/sanitation infrastructure correlates with trachoma burden. Therefore, water/sanitation infrastructure improvement is a worthwhile target in the efforts toward trachoma elimination, but further research on the association between these important public health indicators is warranted.

Neonatal Intensive Care Unit Network Neurobehavioral Scale Profiles in Full-Term Infants: Associations with Maternal Adversity, Medical Risk, and Neonatal Outcomes.

OBJECTIVES: To examine healthy, full-term neonatal behavior using the Neonatal Intensive Care Unit Network Neurobehavioral Scale (NNNS) in relation to measures of maternal adversity, maternal medical risk, and infant brain volumes. STUDY DESIGN: This was a prospective, longitudinal, observational cohort study of pregnant mothers followed from the first trimester and their healthy, full-term infants. Infants underwent an NNNS assessment and high-quality magnetic resonance imaging 2-5 weeks after birth. A latent profile analysis of NNNS scores categorized infants into neurobehavioral profiles. Univariate and multivariate analyses compared differences in maternal factors (social advantage, psychosocial stress, and medical risk) and neonatal characteristics between profiles. RESULTS: The latent profile analysis of NNNS summary scales of 296 infants generated 3 profiles: regulated (46.6%), hypotonic (16.6%), and fussy (36.8%). Infants with a hypotonic profile were more likely to be male (χ2 = 8.601; P = .014). Fussy infants had smaller head circumferences (F = 3.871; P = .022) and smaller total brain (F = 3.522; P = .031) and cerebral white matter (F = 3.986; P = .020) volumes compared with infants with a hypotonic profile. There were no differences between profiles in prenatal maternal health, social advantage, or psychosocial stress. CONCLUSIONS: Three distinct neurobehavioral profiles were identified in healthy, full-term infants with hypotonic and fussy neurobehavioral features related to neonatal brain volumes and head circumference, but not prenatal exposure to socioeconomic or psychosocial adversity. Follow-up beyond the neonatal period will determine if identified profiles at birth are associated with subsequent clinical or developmental outcomes.
