TL;DR: Recent research aimed at improving treatment efficacy; increasing effectiveness; reducing costs; and decreasing unwanted side effects in prevention and cure of anemia is analyzed.
Abstract: The authors briefly describe the epidemiology of anemia, the goals established by the United Nations to combat the problem worldwide, and the difficulties encountered in applying proven effective strategies in public health services to prevent and cure anemia in pregnant women and children, both of which are prime high-risk groups. They analyze recent research aimed at four objectives related to prevention and cure: improving treatment efficacy; increasing effectiveness; reducing costs; and decreasing unwanted side effects. The study indicates that ongoing research could improve prospects for treatment through public health services.

TL;DR: The age distribution of antibody to simian rotavirus (SA‐11) was studied in serum specimens obtained from 399 children aged to 5 years and living in the city of Recife, located in the north eastern region of Brazil, showing a steep rise in the 6‐ to 17‐month‐old age groups.
Abstract: The age distribution of antibody to simian rotavirus (SA-11) was studied in serum specimens obtained from 399 children aged to 5 years and living in the city of Recife (PE), located in the north eastern region of Brazil. Sera were examined for group-specific rotavirus antibody using a blocking enzyme immunoassay (bELISA) and a hemagglutination inhibition antibody (HIA) test, and for anti-VP2, anti-VP4, anti-VP6, and anti-VP7 antibodies using an immunoblotting assay (IBA). Antibody prevalence was similar in all bELISA and HIA assays, showing a steep rise in the 6-to 17-month-old age groups. The results indicate early acquisition of antibody to rotavirus. The majority of children aged 2 to 4 years had bELISA (50% to 60%) and HIA (70% to 81%) antibodies. There was an association in prevalence data obtained by HIA and bELISA with immunoblotting (IBA), revealing four serologic profiles. Children with profiles I and II (60%) respectively had HAI and ELISA antibody or HAI antibody alone and all had immunoprotective antibodies to VP4 and/or VP7. These children were regarded as "immune," resembling convalescent patients with a rotavirus infection. Children with profile III (4%) had no HIA antibody and only non-protective anti-VP6 and/or VP7 antibody, and were considered to be "partially immune." Children with profile IV (36%) had no detectable antibody and were classified as "nonimmune." These children should be considered to be susceptible to rotavirus infection, with the risk of developing clinically severe diarrhea.
