INTRODUCTION: Rural family physicians are often required to meet a wide variety of medical service demands that are otherwise the responsibility of specialty physicians in urban centres. However, many rural physicians enjoy the practice variety and ability to meet patients' medical needs through this wider spectrum of care. We aimed to quantify and summarize the workload and clinical disorders seen by rural family physicians in Saskatchewan relative to urban family physicians. METHODS: We used Saskatchewan Ministry of Health billing data for 2015/16 to compare rural and urban care provision...

INTRODUCTION: Understanding the prognosis of elderly out-of-hospital cardiac arrest (OHCA) patients is vital to informing resuscitation and advanced care planning decisions. However, short-term outcomes such as survival to hospital discharge do not account for post-arrest quality of life. We describe the 12-month functional recovery and health-related quality of life (HR-QOL) of elderly OHCA survivors, including those arresting in aged care facilities. METHODS: We conducted a retrospective analysis of Victorian Ambulance Cardiac Arrest Registry data for all OHCA survivors to hospital discharge aged ≥65 years between 1 January 2010 and 30 June 2016...

BACKGROUND: Cardiac rehabilitation (CR) improves exercise capacity and quality of life while reducing mortality in adults with acquired heart disease. Cardiac rehabilitation has not been extensively studied in adults with congenital heart disease (CHD). METHODS: We performed a prospective, randomized controlled trial (NCT01822769) of a 12-week clinical CR program compared with standard of care (SOC). Participants were ≥16 years old, had moderate or severe CHD, had O2 saturation ≥92%, and had peak O2 consumption ([Formula: see text]) < 80% predicted...

Aging is characterized by a cognitive decline of fluid abilities and is also associated with electrophysiological changes. The vascular hypothesis proposes that brain is sensitive to vascular dysfunction which may accelerate age-related brain modifications and thus explain age-related neurocognitive decline. To test this hypothesis, cognitive performance was measured in 39 healthy participants from 20 to 80 years, using tests assessing inhibition, fluid intelligence, attention and crystallized abilities. Brain functioning associated with attentional abilities was assessed by measuring the P3b ERP component elicited through an auditory oddball paradigm...

The heart is a complex organ composed of multiple cell types, including cardiomyocytes and different non-myocyte populations, all working closely together to determine the hearts properties and maintain normal cardiac function. Connexins are abundantly expressed proteins that form plasma membrane hemichannels and gap junctions between cells. Gap junctions are intracellular channels that allow for communication between cells, and in the heart they play a crucial role in cardiac conduction by coupling adjacent cardiomyocytes...

INTRODUCTION: Successful regulation of emotional states is positively associated to mental health, while difficulties in regulating emotions are negatively associated to overall mental health and in particular associated with anxiety or depression symptoms. A key structure associated to socio-emotional regulatory processes is the central autonomic network. Activity in this structure is associated to vagal activity can be indexed noninvasively and simply by measures of peripheral cardiac autonomic modulations such as heart rate variability...

OBJECTIVES: Reference ranges of left ventricular (LV) parameters from cardiac magnetic resonance (CMR) were established to investigate the impact of ageing and hypertension as important determinants of cardiac structure and function. METHODS: One thousand five hundred twenty-five contrast-enhanced CMRs were conducted in the Study of Health in Pomerania. LV end-diastolic volume (LVEDV), end-systolic volume (LVESV), stroke volume (LVSV), ejection fraction (LVEF), and myocardial mass (LVMM) were determined using long- and short-axis steady-state free-precession sequences...

Importance: Heart failure with preserved ejection fraction (HFpEF) is highly prevalent, yet there are no specific therapies, possibly due to phenotypic heterogeneity. The development of pulmonary hypertension (PH) in patients with HFpEF is considered a high-risk phenotype in need of targeted therapies, but there have been limited hemodynamic and outcomes data. Objective: To identify the hemodynamic characteristics and outcomes of PH-HFpEF. Design, Setting, and Participants: Cohort study of participants who had a right heart catheterization from January 2005 to September 2012 (median [interquartile range] follow-up time, 1578 [554-2513] days) were analyzed...

PURPOSE: Angiopoietin-like proteins (ANGPTLs) 3, 4, and 8 reportedly contribute to progression of metabolic disease, a risk factor for cardiovascular disease (CVD). The purpose of this study was to investigate whether circulating ANGPTL levels are associated with CVD risk after adjustment for potential confounding factors. METHODS: We conducted a single center, cross-sectional study of 988 Japanese subjects undergoing routine health checks. Serum ANGPTL3, 4, and 8 levels were measured using an enzyme-linked immunosorbent assay...

Cardiovascular events are a major cause of early death in the Huntington's disease (HD) population. Dysautonomia as well as deterioration of circadian rhythms can be detected early in the disease progression and can have profound effects on cardiac health. The aim of the present study was to determine if HD patients and premanifest mutation carriers present a higher risk of cardiovascular disease (CVD) than non-mutation carrying controls METHODS: Prospective, cross-sectional, multicentre study of 38 HD mutation carriers (23 premanifest and 15 early-stage patients) compared to 38 age- and gender-matched healthy controls...

Out-of-hospital cardiac arrest (OHCA) is a leading cause of global mortality. Regional variations in reporting frameworks and survival mean the exact burden of OHCA to public health is unknown. Nevertheless, overall prognosis and neurological outcome are relatively poor following OHCA and have remained almost static for the past three decades. In this Series paper, we explore the aetiology of OHCA. Coronary artery disease remains the predominant cause, but there is a diverse range of other potential cardiac and non-cardiac causes to be aware of...

BACKGROUND: Mitral regurgitation is the most common valve disease worldwide but whether the community-wide prevalence, poor patient outcomes, and low rates of surgical treatment justify costly development of new therapeutic interventions remains uncertain. Therefore, we did an observational cohort study to assess the clinical characteristics, outcomes, and degree of undertreatment of mitral regurgitation in a community setting. METHODS: We used data from Mayo Clinic electronic health records and the Rochester Epidemiology Project to identify all cases of moderate or severe isolated single-valvular mitral regurgitation (with no other severe left-sided valvular disease or previous mitral surgery) diagnosed during a 10-year period in the community setting in Olmsted County (MN, USA)...

It is conservatively estimated that 5,000 deaths per year and 20,000 injuries in the USA are due to poisonings caused by chemical exposures (e.g., carbon monoxide, cyanide, hydrogen sulfide, phosphides) that are cellular inhibitors. These chemical agents result in mitochondrial inhibition resulting in cardiac arrest and/or shock. These cellular inhibitors have multi-organ effects, but cardiovascular collapse is the primary cause of death marked by hypotension, lactic acidosis, and cardiac arrest. The mitochondria play a central role in cellular metabolism where oxygen consumption through the electron transport system is tightly coupled to ATP production and regulated by metabolic demands...
