RESUMO
BACKGROUND: Malnutrition is an urgent problem in the developing world, especially for children under 5 years of age. The article describes the utilization of a standard of practice designed to prevent illness in a malnourished, under-5 indigenous population and reinforced by weekly basic health messages taught by lay community health promoters. METHOD: The two villages were chosen for observation after administration of the standard of care among the Maya-Kíché, the most numerous Mayan group in Guatemala. The standard of practice, 20 mg of daily oral zinc, was administered for 10 days in the home and followed by daily vitamin supplementation that continued throughout the 3 months of the project. All patients received four monthly clinic visits, with one of the village groups receiving weekly health promoter visits. RESULTS: Data evaluated after the quality improvement project showed significant differences in adherence to the zinc regimen (χ(2) = 3.677, p ≤ .05) as well as lower rates of diarrheal illnesses (χ(2) = 5.850, p ≤ .05), with both of these improved in the health promoter group. DISCUSSION: This study suggests that the training and implementation of para-health professionals from the lay community in response to specific health care needs could be considered a best practice in developing countries. IMPLICATIONS: Public health professionals are key to health promoter training and direction, and their importance in the global setting cannot be understated.

This study qualitatively examines contrasting parental decision-making styles about family food choices and physical activities as well as willingness to change behaviors among Mexican-American and Mexican immigrant mothers and fathers of school-aged children. Twelve sex-specific focus groups were held in English or Spanish in 2012. Qualitative analysis informed by grounded theory examined parenting styles (ie, authoritative, authoritarian, or permissive), barriers to healthy lifestyle, and parents' stage of change about healthy lifestyles. One third of the 33 participating couples were born in Mexico. The majority of mothers and fathers described being permissive and allowing unhealthy food choices, and a minority of mothers reported more authoritarian approaches to promoting a healthier diet for their children. Mothers were more permissive than fathers about family physical activities and less engaged in these activities. Most mothers and fathers described only contemplating a healthier diet and more physical activity, while wanting their children to have a healthier lifestyle. These data suggest that clinicians need to assess and address differential parental roles when promoting a healthy lifestyle for children. Clinicians should also adopt culturally competent approaches to overcome barriers to parental engagement in diverse aspects of a healthy family lifestyle.

PREMISE OF THE STUDY: Polyploidy plays an important role in race differentiation and eventually speciation. Underlying mechanisms include chromosomal and genomic changes facilitating reproductive isolation and/or stabilization of hybrids. A prerequisite for studying these processes is a sound knowledge on the origin of polyploids. A well-suited group for studying polyploid evolution consists of the three species of Melampodium ser. Leucantha (Asteraceae): M. argophyllum, M. cinereum, and M. leucanthum. METHODS: The origin of polyploids was inferred using network and tree-based phylogenetic analyses of several plastid and nuclear DNA sequences and of fingerprint data (AFLP). Genome evolution was assessed via genome size measurements, karyotype analysis, and in situ hybridization of ribosomal DNA. KEY RESULTS: Tetraploid cytotypes of the phylogenetically distinct M. cinereum and M. leucanthum had, compared to the diploid cytotypes, doubled genome sizes and no evidence of gross chromosomal rearrangements. Hexaploid M. argophyllum constituted a separate lineage with limited intermixing with the other species, except in analyses from nuclear ITS. Its genome size was lower than expected if M. cinereum and/or M. leucanthum were involved in its origin, and no chromosomal rearrangements were evident. CONCLUSIONS: Polyploids in M. cinereum and M. leucanthum are of recent autopolyploid origin in line with the lack of significant genomic changes. Hexaploid M. argophyllum also appears to be of autopolyploid origin against the previous hypothesis of an allopolyploid origin involving the other two species, but some gene flow with the other species in early phases of differentiation cannot be excluded.
