Filter by:The HIV/HEART Aging study (HIVH) is an ongoing, prospective, multicentre trial that was conducted to assess the incidence, the prevalence and the clinical course of cardiovascular diseases (CVD) in HIV-infected patients. The study population includes outpatients from specialized HIV-care units of the German Ruhr region, who were at least 18 years of age, were known to have a HIV-infection and exhibited a stable disease status within 4 weeks before inclusion into the trial. From March 2004 (Pilot phase) to October 2019 (12,5 year Follow-up) 1806 HIV+ patients were recruited in a consecutive manner. The standardised examinations included a targeted assessment of medical history and physical examination. Blood was drawn for comprehensive laboratory tests including HIV specific parameters (CD4 cell count, HIV-1 RNA levels) and cardiovascular items (lipid concentrations, BNP values and renal parameters). Furthermore, non-invasive tests were performed during the initial visit, including additional heart rate and blood pressure measurements, electrocardiogram (ECGs) and transthoracic echocardiography (TTE). Examinations were completed in accordance with previously defined standard operating procedures. CVD were defined as coronary, cerebrovascular, peripheral arterial disease, heart failure or cardiac vitium.
Proper footwear serves to protect the foot against external factors. Balance and functional performance are affected by the level of footwear suitability. This study was designed to investigate the effects of footwear suitability on functional performance levels and balance in the elderly.
Generalization refers to skill transfer under various working spaces following motor practice. The extent of generalization effect links causal to in-depth recognition of error properties during motor practice. Idiom says "imperfect practice makes perfect". It could be beneficial for the elderly to gain superior capacity of balance transfer skill under the short-term productive failure learning environments. In contrast to traditional visual feedback that uses error avoidance training to optimize target balance task, the present 3-year proposal is to propose three potential neuro-cognitive strategies to improve motor skill transfer following stabilometer training. The strategies are expected to enhance opportunities of error experience and motor exploration via modified visual feedback, underlying facilitations of attentional resource and error-related neural networks. In the first year, the neuro-cognitive strategy for balance practice is progressive augmentation of visual error size to improve balance skill transfer. In the second year, the neuro-cognitive strategy for balance practice is visual feedback with virtual uncertainness of motor goal. In the third year, the neuro-cognitive strategy for balance practice is stroboscopic vision. EEG and central of pressure will be processed with non-linear approaches. Graph theory will characterize EEG functional connectivity and brain network efficiency regarding to brain mechanisms for practice-related leaning transfer. Trajectories of central of pressure will be analyzed with stabilogram diffusion analysis to reveal behavior mechanisms for practice-related variations in feedback and feedforward process for error corrections.
Physical Activity (PA) is recognized as the most effective method to prevent falls in the elderly. Yet despite there being a consensus now that Physical Activity (PA) is effective in practice, there remain many obstacles to participation resulting in PA approaches designed to prevent falls actually only benefiting a limited number of elderly subjects.
Age-related changes in body composition, muscular fitness, and metabolic health resulting in the onset of obesity, sarcopenia, and chronic diseases are profound public health issues that are in need of immediate attention. Effective and feasible methods, such as dietary therapies, are needed to improve health in older adults that in turn lead to independence, enhanced quality of life and reduced hospitalizations. Diet quality and dietary protein intake are vital for maintaining body composition, muscle mass and improved physical performance. Malnutrition in dietary protein intake is a major cause of reduced muscle mass, strength, and function in older adults. The Dietary Approaches to Stop Hypertension (DASH) dietary pattern is a high-quality therapeutic diet known to improve health status in various diverse and at-risk populations resulting in improved heart health, maintained cognitive function and reductions in metabolic diseases such as diabetes, metabolic syndrome, and nonalcoholic fatty liver disease. The primary protein recommendations of the DASH diet are poultry and fish and it is recommended to decrease or exclude red meats from the diet. However, studies have demonstrated that lean red meat incorporated into a DASH-like diet doesn't exacerbate cardiovascular health indices in adults, indicating that lean red meat can be included in the DASH diet without negative effects on heart health. Although studies have reported on the DASH diet in older adults, no studies have investigated the effect of the DASH diet containing lean red meat on measures of body composition, muscle mass or metabolic health under controlled-feeding conditions. The purpose of this study was to determine the effect of the DASH diet containing daily intakes of lean red meat on indicators of body composition, muscular fitness and biomarkers of metabolic health in adults 65 and older using controlled-feeding and systems biology approaches.
Thickened liquids are commonly used as an intervention for people with dysphagia (swallowing impairment). However, the field currently lacks a proper understanding of how this intervention works. The overall goal of the project is to collect measurements of bolus flow through the oropharynx (i.e., mouth and throat) during swallowing. The factors that are expected to influence bolus flow include the liquid/food consistency (i.e., thin, slightly-thick, mildly-thick, moderately-thick, extremely thick, solid) and the forces applied during swallowing (i.e., tongue pressures and swallowing muscle contraction). The objective is to determine how these factors interact to influence the flow of a bolus through the oropharynx in healthy swallowing.
This study aims was evaluated the effect of L-arginine on microcirculation, vasoreactivity / endothelial function and vascular smooth muscle of young and old women with Sarcopenia or Type 2 Diabetes Mellitus measured by Nailfold videocapillaroscopy and venous occlusion plethysmography before and after 14 days of consumption 5g oral L-arginine supplementation.
Evaluates an intervention designed to improve everyday memory function, contrasting people receiving the intervention with a group that receives traditional memory strategy training.
STYLAGE® HydroMax is a CE-marketed hyaluronic acid gel intended to improve skin moisturization and elasticity through injection into the dermis of the face, neck, neckline area and back of the hand. In this study, 47 female healthy subjects between the ages of 35 and 65, who have signs of cutaneous dryness and lack of elasticity on the cheek and on the neckline area, who have given her informed consent and met all the eligibility criteria, will be enrolled. One month apart subjects will randomly receive 3 injections of product in one cheek and in one side of the neckline area. Subjects will come to a total of 8 visits over a period of 9 months. Variation of moisturization, elasticity and roughness of treated areas in comparison with non-treated areas will be measured using specific devices by independent evaluators. Global aesthetic improvement, subject satisfaction, pain at injection and safety will also be assessed.
The first phase of the study aims to study the incidence of near-falls. The second phase will be to develop a scale which operationalize balance recovery confidence in the older adults. This study will determine the incidence of near-falls in a sample of community-dwelling older adults and will develop the Balance Recovery Falls-Efficacy scale (BRFES) for the community-dwelling older adults using the COSMIN method. This scale will be used to measure the confidence level of the community-dwelling older adults in their ability to execute balance recovery maneuvers in common, everyday functional activities to prevent a fall.
