Pulmonary arterial hypertension (PAH) occurs in women more than men whereas survival in men is worse than in women. In recent years, much research has been carried out to understand these sex differences in PAH. This article discusses clinical and preclinical studies that have investigated the influences of sex, serotonin, obesity, estrogen, estrogen synthesis, and estrogen metabolism on bone morphogenetic protein receptor type II signaling, the pulmonary circulation and right ventricle in both heritable and idiopathic pulmonary hypertension.
Women and children bear substantial morbidity and mortality as a result of armed conflicts. This Series paper focuses on the direct (due to violence) and indirect health effects of armed conflict on women and children (including adolescents) worldwide. We estimate that nearly 36 million children and 16 million women were displaced in 2017, on the basis of international databases of refugees and internally displaced populations.
Metastatic colorectal cancer outcomes continue to improve, but they vary significantly by race and ethnicity. Hypothesizing that these disparities arise from unequal access to care rather than intrinsic biology, we showed that survival of 103 consecutive patients with metastatic colorectal cancer treated at an academic safety-net hospital that treats the underserved, predominantly minority population of Harris County, Texas, was superior to that of subjects enrolled in the CRYSTAL (Cetuximab Combined with Irinotecan in First-Line Therapy for Metastatic Colorectal Cancer) trial.
Background: The population effects of armed conflict on non-combatant vulnerable populations are incompletely understood. We aimed to study the effects of conflict on mortality among women of childbearing age (15–49 years) and on orphanhood among children younger than 15 years in Africa. Methods: We tested the extent to which mortality among women aged 15–49 years, and orphanhood among children younger than 15 years, increased in response to nearby armed conflict in Africa.
Background & Aims Coffee has anti-inflammatory and hepato-protective properties. In the general population, drinking ≥3 cups of coffee/day has been associated with a 14% reduction in the risk of all-cause mortality. The aim of this study was to investigate the relationship between coffee consumption and the risk of all-cause mortality in patients co-infected with human immunodeficiency virus (HIV) and hepatitis C virus (HCV).
Background China has achieved Millennium Development Goal 4 to reduce under-5 mortality rate by two-thirds between 1990 and 2015. In this study, we estimated the national and subnational levels and causes of child mortality in China annually from 1996 to 2015 to draw implications for achievement of the SDGs for China and other low-income and middle-income countries.
Wood residues from forest harvesting or disturbance wood from wildfire and insect outbreaks may be viewed as biomass "feedstocks" for bioenergy production, to help reduce our dependence on fossil fuels. Biomass removals of woody debris may have potential impacts on forest biodiversity and ecosystem function. Forest-floor small mammals, such as the southern red-backed vole (Myodes gapperi) that typically disappear after clearcut harvesting, may serve as ecological indicators of significant change in forest structure and function.
