Anaemia remains the most prevalent nutritional disorder among women and children in the Middle East and North Africa region. We examined anaemia trends using data from the Egyptian Demographic and Health Surveys. Between 2000 and 2005, the prevalence of anaemia (defined as haemoglobin concentrations <11 g dL(-1) ) increased from 37.04% to over 52% among Egyptian children between 12 months and 36 months of age. We examined the associations of these changes with food consumption, vitamin A administration, recent illness, immunization status, socio-demographic factors and a child's anaemic status. Children under the age of 24 months who had recently been sick and those who resided in Upper Egypt were significantly more likely to be anaemic. Despite significant improvements in water and sanitation facilities, maternal education and asset-based household wealth, there were marked declines in the consumption of nutritive foods and increases in the prevalence of childhood diarrhoea between 2000 and 2005. Placing these analyses in the broader context of Egyptian economic trends suggests that the nutritional basket consumed by Egyptian households between 2000 and 2005 may have shifted towards less nutritive foods with lower costs per calorie, probably in response to economic difficulties and increasing food prices. Shifts in dietary consumption, in conjunction with increases in diarrhoea, are likely contributing to the rapid increase in childhood anaemia in Egypt between 2000 and 2005. National-level fortification efforts may be one way to combat rising levels of anaemia among Egyptian women and children.

In the 1980s, Poland was a medium-endemic country, with one of the highest incidences of hepatitis B in Europe (45/10 inhabitants). Pursuant to the WHO guidelines, obligatory vaccination was introduced in 1994-1996 (as a part of hepatitis B prophylaxis for newborns), and in 2000-2011, all 14-year-olds were vaccinated. To prevent transfusion-transmitted HBV infection (TT-HBV), since the 1970s, each donation has been tested for HBsAg and, since 2005, additionally for the presence of HBV DNA.

This study aims to assess the relationship between the two.
Methods: Participants from the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2012 were selected.

Objective: We examined if racial residential segregation (RRS) - a fundamental cause of disease - is independently associated with air pollution after accounting for other neighborhood and individual-level sociodemographic factors, to better understand its potential role as a confounder of air pollution-health studies.
Methods: We compiled data from eight large cohorts, restricting to non-Hispanic Black and White urban-residing participants observed at least once between 1999 and 2005. We used 2000 decennial census data to derive a spatial RRS measure (divergence index) and neighborhood socioeconomic status (NSES) index for participants' residing Census tracts, in addition to participant baseline data, to examine associations between RRS and sociodemographic factors (NSES, education, race) and residential exposure to spatiotemporal model-predicted PM and NO levels.

Estimating the durability of immunity from vaccination is complicated by unreported re-vaccination, and unobserved natural infection or reexposure, which could result in overestimation of protection longevity. We tested serial cross-sectional serum samples from 2005 to 2015 (N=2,530) for IgG to examine measles seroprevalence, spatiotemporal patterns of titers across regions and antibody dynamics among children aged 1-9 years who grew up during varying measles circulation in Madagascar under a one-dose vaccination schedule. We found that measles seroprevalence has generally decreased over this time period.

All-solid-state lithium metal batteries are regarded as next-generation devices for energy storage due to their safety and high energy density. The issues of lithium dendrites and poor mechanical compatibility with electrodes present the need for developing solid-state electrolytes with high stiffness and damping, but it is a contradictory relationship. Here, inspired by the superstructure of tooth enamel, we develop a composite solid-state electrolyte composed of amorphous ceramic nanotube arrays intertwined with solid polymer electrolytes.
