Biocultural and social determinants of ill health and early mortality in a New Mexican paediatric autopsy sample.

Results: Hispanic children have higher odds of growth stunting than non-Hispanic White children. Native American children die younger and have higher odds of respiratory diseases and porous lesions than Hispanic and non-Hispanic Whites. Rural/urban location does not significantly impact age at death, but housing type does.

Rural Population Health and Aging: Introduction to the Special Issue.

This special issue of the (JRSS) focuses on rural population health and aging. It showcases the work of scholars from several backgrounds and social science disciplines to advance knowledge in a critical field of investigation. Assembled through an open call for submissions coordinated through the National Institute on Aging (NIA) funded Interdisciplinary Network on Rural Population Health and Aging (INRPHA), the collection of articles helps inform a more nuanced understanding of the factors associated with rural places, which often have different health outcomes and aging patterns than their urban counterparts.

Rural Population Health and Aging: Toward a Multilevel and Multidimensional Research Agenda for the 2020s.

The unique health and aging challenges of rural populations often go unnoticed. In fact, the rural United States is home to disproportionate shares of older and sicker people, there are large and growing rural-urban and within-rural mortality disparities, many rural communities are in population decline, and rural racial/ethnic diversity is increasing.Yet rural communities are not monolithic, and although some rural places are characterized by declining health, others have seen large improvements in population health.

Prognostic value of late gadolinium enhancement in clinical outcomes for hypertrophic cardiomyopathy.

Objectives: The objective of this study was to perform a systematic review and meta-analysis of the predictive value of late gadolinium enhancement (LGE) cardiac magnetic resonance (CMR) for future cardiovascular events and death in hypertrophic cardiomyopathy (HCM).

Background: The utility of LGE for detecting myocardial fibrosis is well established. The prognostic value of LGE in HCM has been described in several studies, but controversy exists given the limited power of these studies to predict future events.

Did H1N1 influenza prevention messages reach the vulnerable population along the Mississippi Gulf Coast?

Objective: To identify the primary sources of information utilized by a vulnerable population during the 2009 influenza pandemic and examine disease prevention behaviors related to reports of local H1N1 influenza transmission.

Design: Cross-sectional study.

Setting: Between May 2009 and December 2009, face-to-face interviews were conducted in towns located in 3 Mississippi counties along the Gulf Coast.

Challenges to accessing pediatric health care in the Mississippi delta: a survey of emergency department patients seeking nonemergency care.

Background: Increases in hospital emergency department use have been driven by insured patients with problems accessing primary care services. Access problems are especially pronounced in rural communities with health professional shortages. This qualitative study explored reasons for nonurgent pediatric emergency department use in the Mississippi Delta.

Calcitriol modulation of cardiac contractile performance via protein kinase C.

Vitamin D(3) deficiency enhances cardiac contraction in experimental studies, yet paradoxically this deficiency is linked to congestive heart failure in humans. Activated vitamin D(3) (1alpha,25-dihydroxyvitamin D(3)) or calcitriol, decreases peak force and activates protein kinase C (PKC) in isolated perfused hearts. However, the direct influence of this hormone on adult cardiac myocyte contractile function is not well understood.
