Knowledge of the Stress-Health Link as a Source of Resilience Among Mexicans in the Arizona Borderlands.

Mexicans who migrate to the United States endure significant stressors related to the migration process and social and environmental conditions of life in the United States. Given that chronic stress exposure has been linked to the onset of health conditions, these ecological factors may expose them to increased risk for poor health. However, Mexicans have many positive health outcomes compared to those monitored nationally, making it crucial to understand possible sources of resilience in this population.

Cost of illness due to respiratory syncytial virus acute lower respiratory tract infection among infants hospitalized in Argentina.

Background: Information is scarce regarding the economic burden of respiratory syncytial virus (RSV) disease in low-resource settings. This study aimed to estimate the cost per episode of hospital admissions due to RSV severe disease in Argentina.

Methods: This is a prospective cohort study that collected information regarding 256 infants under 12 months of age with acute lower respiratory tract infection (ALRTI) due to RSV in two public hospitals of Buenos Aires between 2014 and 2016.

The Use of Qualitative Methods to Guide the Development of the Border Resilience Scale in a Participatory Research Study.

U.S.-Mexico border residents experience pervasive social and ecological stressors that contribute to a high burden of chronic disease.

La vida en la frontera: protocol for a prospective study exploring stress and health resiliencies among Mexican-origin individuals living in a US-Mexico border community.

Background: Mexican-origin adults living near the U.S.-Mexico border experience unique and pervasive social and ecological stressors, including poverty, perceived discrimination, and environmental hazards, potentially contributing to the high burden of chronic disease.

"Es Muy Tranquilo Aquí": Perceptions of Safety and Calm among Binationally Mobile Mexican Immigrants in a Rural Border Community.

Perceptions of community can play an important role in determining health and well-being. We know little, however, about residents' perceptions of community safety in the Southwestern borderlands, an area frequently portrayed as plagued by disorder. The qualitative aim of this community-based participatory research study was to explore the perceptions of Mexican-origin border residents about their communities in southern Yuma County, Arizona.

Respiratory Failure and Death in Vulnerable Premature Children With Lower Respiratory Tract Illness.

Background: Efforts to better understand the risk factors associated with respiratory failure (RF) and fatal lower respiratory tract infection (LRTI) in premature children in developing countries are necessary to elaborate evidenced-based preventive interventions. We aim to characterize the burden of respiratory syncytial virus (RSV) and human metapneumovirus (hMPV) LRTI in premature children and determine risk factors for RF and fatal illness in a vulnerable population.

Methods: This is a prospective, population-based, cross-sectional study.

Role for Maternal Asthma in Severe Human Metapneumovirus Lung Disease Susceptibility in Children.

Background: Severity of human metapneumovirus (hMPV) lower respiratory illness (LRTI) is considered similar to that observed for respiratory syncytial virus (RSV). However, differences in severity between these pathogens have been noted, suggesting the degree of illness may vary in different populations. Moreover, a potential association between hMPV and asthma also suggests that hMPV may preferentially affect asthmatic subjects.

Mortality due to Respiratory Syncytial Virus. Burden and Risk Factors.

Rationale: Respiratory syncytial virus (RSV) is the most frequent cause of hospitalization and an important cause of death in infants in the developing world. The relative contribution of social, biologic, and clinical risk factors to RSV mortality in low-income regions is unclear.

Objectives: To determine the burden and risk factors for mortality due to RSV in a low-income population of 84,840 infants.

Macronutrients during pregnancy and life-threatening respiratory syncytial virus infections in children.

Rationale: Respiratory syncytial virus (RSV) is an important cause of hospitalization and death in infants worldwide. Most RSV deaths occur in developing countries, where burden and risk factors for life-threatening illness are unclear.

Objectives: We defined the burden of life-threatening (O(2) saturation [O(2) sat] ≤ 87%) and fatal RSV infection, and characterized risk factors for life-threatening disease in hospitalized children.
