Association between coal and firewood combustion and hospital admissions and mortality in Chile 2015 - An ecological approach.

Introduction And Objective: Burning coal and firewood generates toxic emissions that are associated with respiratory illness, cardiovascular disease, and even death. The aim of the study is to evaluate the association between county-level prevalence of household coal and firewood use and health outcomes, including total, respiratory, and cardiovascular mortality, as well as total and respiratory hospitalization rates.

Material And Methods: The ecological study included data on the use of household coal and firewood in 139 counties obtained from the 2015 Chilean National Socio-economic Characterization Survey.

Extracorporeal Membrane Oxygenation Support in a Young Patient With COVID-19 Infection.

Critically ill patients with coronavirus disease 2019 (COVID-19) infection often require mechanical ventilation, and still many of them will progress to worsening hypoxia and death. Veno-venous extracorporeal membrane oxygenation (VV-ECMO) has been used in some centers, but its role in the setting of COVID-19 infection is still unclear to date. We describe a case of a young female patient with obesity but otherwise no other underlying medical conditions who was admitted with respiratory failure secondary to COVID-19.

PERK Is a Haploinsufficient Tumor Suppressor: Gene Dose Determines Tumor-Suppressive Versus Tumor Promoting Properties of PERK in Melanoma.

The unfolded protein response (UPR) regulates cell fate following exposure of cells to endoplasmic reticulum stresses. PERK, a UPR protein kinase, regulates protein synthesis and while linked with cell survival, exhibits activities associated with both tumor progression and tumor suppression. For example, while cells lacking PERK are sensitive to UPR-dependent cell death, acute activation of PERK triggers both apoptosis and cell cycle arrest, which would be expected to contribute tumor suppressive activity.

[Prevalence of infections by Chlamydia trachomatis and Neisseria gonorrhoeae among high school students in the Sabana Central area of Cundinamarca, Colombia].

Introduction: Infections by Chlamydia trachomatis and Neisseria gonorrhoeae are the two most common bacterial sexually transmitted infections in the world. These infections affect principally less than 25-year-old individuals with sexual, reproductive and maternal and child health consequences.

Objective: This study sought to estimate the prevalence of C.

[Symptoms of anxiety and depression in adolescents between 10 to 17 year-old attending schools in Chía, Colombia].

Objective: This study was aimed at estimating the prevalence of symptoms of depression and anxiety amongst 10 to 17 year-old adolescents still attending school using the CDI and SCARED questionnaires for early screening in Chía, a town near Bogota, from 2008 to 2010.

Method: This was a cross-sectional study of prevalence.

Results: 37% of the 538 adolescents interviewed had anxiety symptoms, 12.
