Obesity is a major health concern in Hispanic populations. This study evaluated the epidemiology of obesity and associated factors among Hispanics using the data from the 2013-2014 National Health and Nutrition Examination Survey. Among the 1241 participants (20 years of age or older), the prevalence rates were as follows: overweight, 77.1%; obesity, 42.4%; and central obesity, 57.0%. These rates were consistent throughout most age groups. Significantly, more females than males were obese. Higher obesity rates were seen among those with diabetes, high cholesterol, hypertension, heart disease, and arthritis...

For cancer survivors, who also often present with co-existing health conditions, exercise testing is often performed using submaximal protocols incorporating linear heart rate response for estimating the cardiorespiratory capacity and assessing exercise tolerance. However, use of beta-blocker medications, during sub-maximal protocols based on linear HR response can be problematic. Rating of perceived exertion (RPE), which takes into account an individual's overall perception of effort, can be used as a complementary tool that does not rely solely on the heart rate response to increased workload...

OBJECTIVE To date, treatment of complex unruptured intracranial aneurysms (UIAs) remains challenging. Therefore, advanced techniques are required to achieve an optimal result in treating these patients safely. In this study, the safety and efficacy of rapid ventricular pacing (RVP) to facilitate microsurgical clip reconstruction was investigated prospectively in a joined neurosurgery, anesthesiology, and cardiology study. METHODS Patients with complex UIAs were prospectively enrolled. Both the safety and efficacy of RVP were evaluated by recording cardiovascular events and outcomes of patients as well as the amount of aneurysm occlusion after the surgical clip reconstruction procedure...

Though millions of people practice yoga to reduce stress and improve their mood, it is unclear which aspect of yoga is responsible for these effects. To investigate relevant aspects, or "limbs" of yoga, participants who were novices in the practice of yoga engaged in a single yoga manipulation (i.e., poses, breath work, meditation, or listening to a lecture about yoga) for 20 min before experiencing a mild stressor. Participants' heart rate, blood pressure, mood, and anxiety level were assessed, both immediately after the yoga manipulation and after the mild stressor...

Temperature effects on cardiac autonomic tonus in amphibian larval stages have never been investigated. Therefore, we evaluated the effect of different temperatures (15°C, 25°C, and 30°C) on the cardiorespiratory rates and cardiac autonomic tonus of premetamorphic bullfrog tadpoles, Lithobates catesbeianus To this end, a non-invasive method was developed to permit measurements of electrocardiogram (ECG) and buccal movements (fB ; surface electromyography of the buccal floor). For evaluation of autonomic regulation, intraperitoneal injections of Ringer's solution (control), atropine (cholinergic muscarinic antagonist), and sotalol (β-adrenergic antagonist) were performed...

High income and wealth inequality corresponds with high rates of various health and social problems. One possible factor that could be contributing to this correlation is stress experienced by those being treated unfairly in an unequal society. The present experiment attempted to simulate aspects of income inequality in a lab setting while recording several measures of stress. Participants (n=96) were assigned to one of four groups and played a memory game against a confederate opponent to earn "money" to spend in a lab market...

INTRODUCTION: The increase in obesity rates in the U.S. and other less developed industrial countries have led to a worldwide epidemic of chronic disease states. Increased obesity rates are implicated in the treatment failures for illnesses such as coronary artery disease, diabetes, heart failure, hypertension and cancer. Effective prevention of obesity through diet and exercise contributes to the successful medical management of multiple chronic disease states. OBJECTIVE: Review the last 10 years of literature (2006-2016) on the effects of diet and exercise as they relate to the prevention of chronic disease...

An important consideration in the design of a practical system to restore walking in individuals with spinal cord injury is to minimize metabolic energy demand on the user. In this study, the effects of exoskeletal constraints on metabolic energy expenditure were evaluated in able-bodied volunteers to gain insight into the demands of walking with a hybrid neuroprosthesis after paralysis. The exoskeleton had a hydraulic mechanism to reciprocally couple hip flexion and extension, unlocked hydraulic stance controlled knee mechanisms, and ankles fixed at neutral by ankle-foot orthoses...
