This paper is an ethnography of a four-year, multi-disciplinary adolescent sexual and reproductive health intervention in Bolivia, Nicaragua and Ecuador. An important goal of the intervention – and of the larger global field of adolescent sexual and reproductive health – is to create more open parent-to-teen communication. This paper analyzes the project's efforts to foster such communication and how social actors variously interpreted, responded to, and repurposed the intervention's language and practices. While the intervention emphasized the goal of ‘open communication,’ its participants more often used the term ‘confianza’ (trust). This norm was defined in ways that might – or might not – include revealing information about sexual activity. Questioning public health assumptions about parent–teen communication on sex, in and of itself, is key to healthy sexual behavior, the paper explores a pragmatics of communication on sex that includes silence, implied expectations, gendered conflicts, and temporally delayed knowledge.

Purpose of reviewEndometriosis is a complex benign gynaecologic condition with heterogenous presentations and a large impact on the global healthcare system and on the quality of life for millions of women. Currently, the gold standard for diagnosis involves direct visualization of lesions during surgery confirmed by histopathological diagnosis, resulting in an average delay in its initial diagnosis of 8--10 years. Therefore, the search for noninvasive diagnostic testing options has been subject to a large body of research. Recent findingsMultiple potential biomarkers have been explored for noninvasive testing for endometriosis, including glycoproteins, inflammatory cytokines, immunological molecules, angiogenesis markers, hormones, micro RNAs (miRNAs), proteomics, metabolomics, genomics and the microbiome. SummaryAlthough there are challenges to consider, areas for real promise and advancement in the noninvasive diagnosis of endometriosis are currently being explored with real promise in the area of miRNAs, proteomics, metabolomics, genomics and the microbiome.

background: among the many processes responsible for antimicrobial resistance, inappropriate antibiotic use and self-medication are major public health concerns. To tackle antibiotic resistance and its widespread misuse, is important to identify the social, cultural, and economic differences associated with the problem. Objective: to determine the percentage of antibiotics used without medical prescription in children under five years old with symptoms of upper respiratory tract infection according to their families' socioeconomic characteristics in Ecuador. Materials and Methods: a cross-sectional design was set, using a structured questionnaire to assess mothers who attended urban and rural primary health care units with their children under five years old and belonged to the middle or lower social strata. A sample of 947 individuals was obtained from February to April 2011. Informed consent was acquired from those willing and eligible participants. The descriptive analysis used frequencies, percentages, means, standard deviation and chi-square. Quantitative information was processed using SPSS version 17. results: those from lower socioeconomic strata used antibiotics to treat symptoms of upper respiratory infections of their children without medical prescription in a higher percentage (35.57%) than middle socioeconomic strata (27.7%, p<0.01). Mothers who had university level education had more knowledge about measures to prevent antibiotic resistance (57.14%) than those with only a primary school education (13.59% p<0.05). conclusion: antibiotic use in children under five years old with symptoms of upper respiratory infection is high, mainly among those study participants corresponding to lower socioeconomic strata who mostly live in the rural area.

El presente estudio tiene por objetivo valorar económicamente el recurso hídrico que provee la Microcuenca Quillusara en Celica-Ecuador e identificar los determinantes de la disposición a pagar (DAP) para la conservación del recurso. Para ello se utilizó el método de valoración contingente y un modelo econométrico LOGIT. La obtención de la información se realizó a través de una encuesta aplicada a 374 usuarios del servicio de agua de la ciudad. Se encontró que el 78.6% de la población encuestada está dispuesta a pagar por la conservación de las fuentes de agua. Además, el estudio reveló una DAP de 0.92 USD/mes, este valor representa un importante insumo para orientar las decisiones de política pública sobre el cuidado y protección de las fuentes de agua en el cantón.
