Preventing Teen Pregnancy Among Latinos: Recommendations from Research, Evaluation, and Practitioner Experience
Despite recent and dramatic declines in the rate of childbearing among Latino adolescents, that rate is still the highest among the major racial and ethnic groups in the United States. This fact underscores the need for effective interventions designed specifically to reduce teen pregnancy in this population. Child Trends examined the determinants of early childbearing among Latinos from multiple perspectives to develop a research-based pregnancy prevention approach for Latino adolescents. Specifically, we drew from research studies, program evaluations, and practitioner insights to identify,develop, or adapt promising program models for a Latino population.This brief highlights ways that adolescents' individual attitudes and behaviors, as well as family and parents, peers, and romantic partners, can help or hinder their desires to avoid teen pregnancy. Further, the brief addresses the need for programs and policy makers torecognize these influences and respond accordingly. Based on the findings outlined in this brief, Child Trends developed eight key recommendations for consideration in future intervention efforts

Porcine colonization of the Americas: a 60k SNP story
The pig, Sus scrofa, is a foreign species to the American continent. Although pigs originally introduced in the Americas should be related to those from the Iberian Peninsula and Canary islands, the phylogeny of current creole pigs that now populate the continent is likely to be very complex. Because of the extreme climates that America harbors, these populations also provide a unique example of a fast evolutionary phenomenon of adaptation. Here, we provide a genome wide study of these issues by genotyping, with a 60k SNP chip, 206 village pigs sampled across 14 countries and 183 pigs from outgroup breeds that are potential founders of the American populations, including wild boar, Iberian, international and Chinese breeds. Results show that American village pigs are primarily of European ancestry, although the observed genetic landscape is that of a complex conglomerate. There was no correlation between genetic and geographical distances, neither continent wide nor when analyzing specific areas. Most populations showed a clear admixed structure where the Iberian pig was not necessarily the main component, illustrating how international breeds, but also Chinese pigs, have contributed to extant genetic composition of American village pigs. We also observe that many genes related to the cardiovascular system show an increased differentiation between altiplano and genetically related pigs living near sea level.WBP is funded by COLCIENCIAS (Francisco José de Caldas fellowship 497/2009, Colombia), CAS thanks grants from CAPES and EMBRAPA (Brazil), YRC is recipient of a PhD studentship from MICINN (Spain, ref.

Antifungal Saponins from the Maya Medicinal Plant Cestrum schlechtendahlii G. Don (Solanaceae)
Bioassay-guided fractionation of the crude extract (80% EtOH) of the leaves of Cestrum schlechtendahlii, a plant used by Q'eqchi' Maya healers for treatment of athlete's foot, resulted in the isolation and identification of two spirostanol saponins (1 and 2). Structure elucidation by MS, 1D-NMR, and 2D-NMR spectroscopic methods identified them to be the known saponin (25R)-1β,2α-dihydroxy-5α-spirostan-3-β-yl-O-α-l-rhamnopyranosyl-(1 → 2)-β-d-galactopyranoside (1) and new saponin (25R)-1β,2α-dihydroxy-5α-spirostan-3-β-yl-O-β-d-galactopyranoside (2). While 2 showed little or no antifungal activity at the highest concentration tested, 1 inhibited growth of Saccharomyces cerevisiae (minimum inhibitory concentration (MIC) of 15-25 μM), Candida albicans, Cryptococcus neoformans, and Fusarium graminearum (MIC of 132-198 μM)
