Filter by:The purpose of this study is to provide new insights into the pathophysiology of emergency hematopoiesis detected in severe COVID-19 patients. The investigators aim to explore the ability of calprotectin to induce an immunosuppressive myeloid program at the hematopoietic stem and progenitor cell (HSPC) level, and to identify the receptor(s) involved in this effect. Since patients with a hematological malignancy demonstrate a very high propensity to develop a severe COVID-19, the investigators will explore how HSPCs collected from patients with a myeloid malignancy respond to calprotectin.
To evaluate safety and efficacy of an accelerated deep brain Transcranial Magnetic stimulation (adTMS) and transcutaneous direct current stimulation (tDCS) protocol in an elderly depressed patient population
This study is a multi-center observational study, led by the Department of Geriatrics, Peking Union Medical College Hospital, with 99 tertiary hospitals as sub-centers. Patients in the geriatrics department from September 2020 to September 2021 are consecutively enrolled .Basic information and nutritional risk assessment is registered and the outcome within 90 days after hospitalization will be recorded.Daily energy, protein and fiber are 75% of the target amount as the standard for feeding.
Today's world is characterized among other things by a progressive increase in the aging population, due to a decrease in the birth rate and an increase in life expectancy. In developed countries, the number of older people is increasing, largely due to significant advances in health sciences and new life habits. The aim of this study is to describe an active population over 60 years old, which complies with the concept of successful aging, in order to know its characteristics both at a physical and mental health level and to be able to make recommendations from physiotherapy. Active people over 60 years of age recruited from two associations (Amics de la Nau Gran, and Hogares) from the city of Valencia, Spain will be part of the study. Pain was assessed using the Visual Analogue Scale, the level of physical activity performed using the IPAQ questionnaire, quality of life using the SF-12v2, sleep quality using the Pittsburg questionnaire, and mood using the depression scale and Goldberg's anxiety, as well as functional tests to assess respiratory status.
With the onset of the sixth decade in life, degenerative processes affect the neuromuscular system in terms of losses in muscle strength (dynapenia) and muscle mass (sarcopenia). Neural (e.g., numerical loss of alpha motoneurons) and morphological factors. Borde et al. 123 number and size of particularly type-II muscle fibers), as well as their interaction, are responsible for age-related declines in muscle strength and mass. There is evidence that muscular weakness is highly associated with impaired mobility and an increased risk for falls. Moreover, lower extremity muscle weakness was identified as the dominant intrinsic fall-risk factor with a five-fold increase in the risk of falling. An anti-gravity treadmill allows users to walk or run in a reduced body weight environment. The user walks or runs on a treadmill belt surrounded by an enclosed, air-filled chamber. When air pressure increases, an upward force offloads the weight of the runner and decreases the percentage of body weight (BW%) experienced upon foot impact. So, a research question was developed in our mind after the literature review. Is there any effect of AGT training on fall risk of older adults?
Geriatric Day Hospitals (GDH) of the McGill University Health Centre and l'Institut de Gériatrie de Montreal offer comprehensive rehabilitation programs including physiotherapy and medical care, but no dietetic counselling for the attending frail population at high risk of malnutrition. This study aims to implement a multi-nutrient supplement to further improve nutritional status, physical function and capacity. A whey protein, leucine, vitamin D and omega-3 fatty acid supplement ingested during 16 weeks will be tested versus an isocaloric placebo on measures of physical performance and muscle mass and strength, in GDH participants. The specific objective of this pilot-study is to test feasibility and adherence; pilot data could lead to a larger trial.
The Integrating Health promotion with and for Older People eHealth (IHOPe) project is expected to contribute vital knowledge on how older peoples capabilities and societal resources can be used in a more efficient way to promote health, self-management and enhance teamwork in partnership.The aim is to describe and evaluate this person-centered e-support intervention that promotes a sustainable partnership between community-dwelling frail older people and health and social care professionals. A digital platform, co-created with users and designed to create inclusion of individuals who today are living in a digital alienation, will be used in the health planning. In IHOPe frail older people will be able to identify their potential health issues but also their resources together with team partners from health- and social care, family or societal representatives. The intervention consists of person-centered phone calls with a health care professional as well as access to a digital platform that is accessible to the old person and invited team-partners. The project includes a randomized controlled trial, a process evaluation and a health economic evaluation. People 75 years or older screened as frail will be included. Also, in the process evaluation team-partners using the digital platform will be included. Specifically, this project is expected to reduce hospitalizations, result in improved or retained self-efficacy whilst being cost effective. Additionally, the project is expected to enhance frail older peoples opportunities to participate as an equal partner in their contacts with health and social services.
The primary aim is to study the short-term outcome of elderly ICU patients (≥ 70 years) suffering from COVID-19 using a multicenter and multi-national approach. The secondary aim is to investigate the properties of a simple frailty scale in this cohort, and in particular if this is an instrument that can be used for outcome prediction in this group. In addition, various other parameters of potential relevance for older critically ill patients will be studied.
Postoperative cognitive dysfunction (POCD) is more common in older patients, and increased insulin resistance is an important factor for POCD. Fasting before surgery is performed to reduce the incidence of pulmonary aspiration after anesthesia. However, prolonged fasting increases insulin resistance. Recently, it is recommended to minimize fasting times and consume carbohydrate drinks before surgery. Therefore, the investigators investigate whether preoperative carbohydrate drinks can reduce insulin resistance in the elderly patients. Fifty patients (age>65 years) scheduled for arthroplasty will be divided into carbohydrate (n=28) and control (n=28) groups. Randomly selected patients of the carbohydrate group are given 400ml of 12.8 g/100 ml carbohydrate beverage 2-3 hours before their scheduled operation. In contrast, patients in the control group are fasted from water 2 h before surgery according to standard protocol.
Regularly interrupting sedentary behavior (SB) with activity breaks may attenuate postprandial glucose (PPG) excursions and improve glycemic control. The investigators aimed to determine the effect of interrupting 7 hours of prolonged sitting with brief bouts of moderate physical activity (PA) (alternating between up/down stairs and sit/stand up from the chair) on postprandial glucose (PPG) responses in comparison with uninterrupted sitting. In addition, the investigators aimed to examine the effects of 2 weeks of detraining (DT) on PPG on both protocols. Non-diabetic, trained older adults (n = 15) will be recruited for a randomized crossover trial with two treatments performed in two different training conditions: 1) uninterrupted sitting protocol (CON); 2) seated with 2-minutes bouts of moderate PA every 30 minutes (INT). Both protocols will be performed in a trained condition and after 2 weeks of DT. In the early morning of each trial, participants will do an oral glucose tolerance test (OGTT) and 2 blood samples will be collected (fasting and after 2 hours); 2.5 hours after, participants will begin the protocol and two standardized meals will be provided (0 hours and at 3 hours). An iPro2 continuous glucose monitoring (CGM) system will record the average interstitial glucose concentration every 5 minutes. Positive incremental area under the curve (iAUC) and total area under the curve (pAUC) for glucose as well as mean glucose (MG) will be calculated using Matlab. Differences between both protocols and between the two different moments will be examined using generalized estimation equation (GEE), adjusting for sex and age (CI 95%).
