Filter by:This project was aimed to evaluate the effectiveness of the competence training program in improving the knowledge and skills of volunteer work, the motivation for volunteering, self-efficacy, and satisfaction with volunteer work among older volunteers.
Study BTI-101 is a Phase 1, randomized, double-blind, placebo-controlled, dose escalation, parallel design study to evaluate the safety, tolerability, and pharmacokinetics of IV rhu-pGSN or saline placebo administered as 5 doses each of 6, 12, 18, or 24 mg/kg of body weight. Each of 4 dosing cohorts will include 8 subjects randomized 3:1 rhu-pGSN:placebo (6 rhu-pGSN subjects:2 placebo subjects). Subjects will be healthy adult volunteers 18-55 years of age.
Lumbar plexus block is described as a difficult block, thus requiring experienced practitioners. Many techniques have been used to date, notably anatomical landmarks, neurostimulation, and ultrasound-guided techniques. Among ultrasound-guided techniques, the "Trident" technique was described in 2006, while the "Shamrock" technique was described in 2013. Trident consists in putting the probe sagittally next to the lumbar spine and injecting local anesthetic around the lumbar plexus inside the psoas muscle at the level of L4. It is an out-of-plane puncture. Shamrock puts the probe transversely on the iliac crest. Authors of the 2013 article said the image obtained with this technique was an image of L4. This technique allows an in-plane puncture, which is a safe technique.
The investigators aim to determine the immune status of the employees of the cantonal police of Bern against SARS-CoV-2 over a period of 1 year, and to investigate the risk profile of the study participants and their risk of SARS-CoV-2 exposure in their working and private environments, as well as to evaluate the use of personal protective equipment at potential exposure instances.
Aging is associated with multiple deteriorations of the neuromuscular system. Given the increase in life expectancy, the investigators can now distinguish old adults (>60 years old) who conserve their neuromuscular capacities with regular physical activity and very old adults (>80 years old) who suffer from an inexorable decline, even if the number of octogenarians and their quality of life are progressively increasing. However, the most part of the literature on fatigue and neuromuscular capacity with aging focused on isometric tasks. The results showed a significant decrease in maximal force production capacity and a greater resistance to fatigue for old people compared to the young population. When fatigue is induced trough dynamic contractions, greater fatigability was observed in old adults compared to young adults. Investigations performed on the population aged over 80 years old are rare, showing greater fatigability in octogenarians than old men (aged 60-80 years old) during isometric tasks. The knowledge about the effects of dynamic contractions in this population are limited, and performed uniquely in single leg isokinetic mode. Evaluations that require the use of both legs and higher muscle mass involved in the task (cycloergometer) are needed. Understanding neuromuscular fatigue and fatigability across different exercise modalities is necessary to set adapted physical activity programs aimed to maintain autonomy in older individuals.
The aim of this study is to determine how inflammatory resolution impacts cardiometabolic health and disease in subjects that are either lean (18.5-24.9 kg/m2), overweight (25.0-29.9 kg/m2) or obese (>30.0 kg/m2).
Visual analog scales (VAS) are one of the most common tools used in questionnaires. VAS are validated for pain and stress for example on a horizontal, non-calibrated line of 100 mm, ranging from very low (0) to very high (100). Nowadays, most VAS are used on questionnaires on internet. However, the influence of screen sizes on responses to visual analog scales were never studied.
In this study, doctors will "prescribe" volunteer work for their patients. The investigators are determining whether it is feasible for providers to recommend volunteering to their patients, and whether patients who are recommended this "treatment" actually do volunteer work (i.e., find it "acceptable"). The study is focused on uninsured patients at Loyola Medicine's Access to Care (ATC) Clinic. The study's secondary aim is to determine whether or not engaging in volunteer work yields health benefits.
This study is meant to evaluate the Health TAPESTRY volunteer program. The objective of this study is to explore volunteer experiences in Health TAPESTRY in terms of implementation and to understand how participation in Health TAPESTRY as a volunteer is related to compassion, self-reported physical activity, quality of life, and attitudes toward older adults.
Evidence is accumulating that there are sex differences in energy and substrate metabolism. The positive or negative consequences of such metabolic differences between men and women need to be evaluated with respect to health outcomes. The importance of aberrant lipid metabolism in metabolic diseases such as obesity, diabetes and cardiovascular disease, makes understanding the distinction between "normal" vs aberrant critical to future treatment and prevention strategies. Sex differences in the effects of catecholamines on lipid metabolism and substrate oxidation in non-obese, healthy individuals, have been consistently observed. In addition, distinct differences in men and women exist in the distribution of body fat, with men typically having greater central adiposity than women. Accumulation of fat in the abdomen is associated with an increased risk for metabolic abnormalities such as hyperlipidemia and insulin resistance. In the current study, therefore, the role of testosterone in determining the sex differences in catecholamine mediated substrate metabolism and deposition of dietary fat into upper versus lower body adipose tissue depots will be addressed.
