Perioperative Fluid Management.

The medical complexity of the geriatric patients has been steadily rising. Still, as outcomes of surgical procedures in the elderly are improving, centers are pushing boundaries. There is also a growing appreciation of the importance of perioperative fluid management on postoperative outcomes, especially in the elderly.

An Audit and Feedback Intervention to Improve Internal Medicine Residents' Performance on Ambulatory Quality Measures: A Randomized Controlled Trial.

Audit and feedback is an effective method to improve attending physician performance. However, there are limited data on how audit and feedback impacts care provided by resident physicians. The authors conducted a 3-arm randomized clinical trial among internal medicine resident physicians to examine the impact of an audit and feedback intervention on ambulatory quality measures (AQMs).

Antioxidants prevent inflammation and preserve the optic projection and visual function in experimental neurotrauma.

We investigated the role of oxidative stress and the inflammasome in trauma-induced axon degeneration and vision loss using a mouse model. The left eyes of male mice were exposed to over-pressure air waves. Wild-type C57Bl/6 mice were fed normal, high-vitamin-E (VitE), ketogenic or ketogenic-control diets.

Obesity and the Obesity Paradox in Heart Failure.

Obesity continues to be a public health problem in the general population, and also significantly increases the risk for the development of new-onset heart failure (HF). However, in patients with already-established, chronic HF, overweight and mild to moderate obesity is associated with substantially improved survival compared to normal weight patients; this has been termed the "obesity paradox". The majority of studies measure obesity by body mass index, but studies utilizing less-frequently used measures of body fat and body composition, including waist circumference, waist-hip ratio, skinfold estimates, and bioelectrical impedance analysis also confirm the obesity paradox in HF.

Impact of cardiorespiratory fitness on the obesity paradox in patients with systolic heart failure.

Although high body mass index (BMI) is associated with improved outcomes in established heart failure (HF), the impact of cardiorespiratory fitness on this obesity paradox is less clear. We studied 1,675 patients with systolic HF who underwent cardiopulmonary exercise testing at a single university center (77.4% men, mean age 52.

Obesity and the obesity paradox in heart failure.

Obesity is a growing public health problem in the general population, and significantly increases the risk for the development of new-onset heart failure (HF). However, in the setting of chronic HF, overweight and mild to moderate obesity is associated with substantially improved survival compared to normal-weight patients. Evidence exists for an "obesity paradox" in HF, with the majority of data measuring obesity by body mass index, but also across various less-frequently used measures of body fat (BF) and body composition including waist circumference, waist-hip ratio, skinfold estimates of percent BF, and bioelectrical impedance analysis of body composition.

The obesity paradox in men versus women with systolic heart failure.

Obesity is common in heart failure (HF) and is associated with improved outcomes, a finding often termed the "obesity paradox." Although fat distribution varies by gender, the role of obesity in the outcomes of women compared to men with HF has not been well studied. In a cohort of patients with advanced systolic HF followed at a single university center, 2,718 patients had body mass indexes (BMIs) measured at baseline, and 469 patients with HF had waist circumferences (WCs) measured at baseline.

Waist circumference, body mass index, and survival in systolic heart failure: the obesity paradox revisited.

Background: Higher body mass index (BMI) is associated with improved heart failure (HF) survival, but the role of waist circumference (WC) in HF outcomes has not been studied.

Methods And Results: A total of 344 patients with advanced systolic HF had WC and BMI measured at presentation. High WC was defined as ≥88 cm in women and ≥102 cm in men, and high BMI as ≥25 kg/m(2).

Caregiver role strain of older workers.

Unlabelled: The purpose of this study was to measure role strain in older adult workers who were also caregivers of frail elders according to Komarovsky's role strain theory, and to determine whether different patterns of role strain exist for male worker-caregivers than females.

Method: Researchers developed the Job-Caregiver Role Strain Scale Survey, which was adapted from a survey that measured role strain in working parents and spouses. Surveys were distributed to 11 male and 34 female older workers who were also caregivers.
