Online patient communities for weight loss abound but may include misinformation. Systematic reviews and meta-analyses suggest that social media-delivered lifestyle interventions modestly impact weight, yet how social media was used and participant engagement varies widely. The rapidly changing social media landscape poses challenges for patients, clinicians, and researchers. Research is needed on how patients can establish supportive communities for weight loss and the role of clinicians in these communities. Emerging research on meaningful engagement in, and the efficacy and cost-effectiveness of, social media-delivered lifestyle interventions should provide insights into how to leverage social media to address the obesity epidemic.
OBJECTIVE: To analyze the emergency hospitalizations trend for ambulatory care sensitive conditions between 2011 and 2015 in a health insureance company of the Colombian Social Security General System. METHODS: A log-linear analysis based on age-adjusted hospitalization rates for ambulatory care sensitive conditions in the Entidad Promotora de Salud Sanitas was used to estimate the annual percentage change in these rates and to identify joinponts of the rates. Data was collected from administrative sources. RESULTS: There were 38,530 hospitalizations for ambulatory care sensitive conditions in 26,501 Entidad Promotora de Salud Sanitas enrollees, with a significant decrease in hospitalization rates. The annual percentage change estimated for the period was -9.5% with no significant joinpoints throughout the time interval. CONCLUSIONS: A significant reduction in hospital admissions due to ambulatory care sensitive conditions in Entidad Promotora de Salud Sanitas enrollees were reported for the last five years in this study.
<p>La Preeclampsia (PE) es un trastorno multisistémico, exclusivo de la gestación humana y responsable de aproximadamente 44.000 muertes maternas anuales a nivel mundial; esta enfermedad está asociada a múltiples complicaciones tanto en la madre como en el feto, sin embargo, su etiología no se encuentra totalmente dilucidada y en consecuencia ha sido difícil definir estrategias válidas de predicción. La PE es una enfermedad compleja y comparte diferentes factores de riesgo con las enfermedades cardiovasculares; como la obesidad, hipertensión arterial, resistencia a la insulina y dislipidemias. Con esto se evidencia que algunas alteraciones en los niveles lípidos y apolipoproteínas, se asocian con mayor peroxidación lipídica y estrés oxidativo lo cual puede desencadenar en disfunción endotelial para ambas patologías. Por tanto, la exploración de la evidencia de una asociación entre las fracciones lipídicas y riesgo de PE, puede aportar nuevo conocimiento en torno a la etiología de esta enfermedad. En la presente revisión, se plantearán las principales implicaciones biológicas de las alteraciones del perfil lipídico y apolipoproteínas en la génesis de la PE. Se describirán los estudios observacionales que se han aproximado a su evaluación y se identificarán sus principales debilidades metodológicas, con el fin de plantear estrategias para una evaluación integral de esta vía fisiopatológica, con posibles implicaciones predictivas de la enfermedad.</p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
