Filter by:As a consequence of the impending increase in life expectancy, there is urgent need to adopt life-saving interventions, such as hematopoietic stem cell transplantation, (SCT) in groups of patients that have been regarded as unsuitable for such medical procedures owing to their advanced age. However, a growing body of evidence shows that age per se does not account for a reliable estimation of the capability of an individual to cope with the stressful procedure of SCT and to deal with the cognate adverse effects. Recent literature shows that changes in epigenetic markers (i.e. the extent of methylation) at specific loci of genomic DNA marks the rate of aging and allows for the estimation of the so called "biologic aging." In other words, individuals of the same chronologic age may turn out to be older or younger respect when their biologic age is assessed. This latter is expected to be tightly linked to changes in major homeostatic mechanisms and consequently to be in relationship the chance of successful SCT. The primary objective of the study is the study of DNA in patients undergoing allogeneic haematopoietic stem cell transplantation. DNA will be assessed for the extent of methylation, which will be also in relationship with circulating exogenous DNA (i.e the microbiome).
The Atlas of Retinal Imaging in Alzheimer's (ARIAS) study is a 5-year study examining the natural history of retinal imaging biomarkers associated with disease risk, disease burden, and disease progression in Alzheimer's disease (AD). The objective of this project is to create a 'gold standard' reference database of structural anatomic and functional imaging of the retina, in order to enable the identification and development of both sensitive and reliable markers of AD risk and/or progression. Our ultimate goal is to develop a new screening protocol that identifies changes related to AD 10-20 years before AD is clinically visible.
The purpose of this project is to determine the effect of various interventions to improve patient outcome as defined by hospital free days at day 90 for adult patients undergoing elective surgery. Within this project, multiple studies may be conducted. The structure of this project permits: - the testing of multiple treatments at the same time within the same patient - the use of early study results to provide better treatment options to future patients - the removal of treatments which are shown to be less effective than the other treatments - the addition of new treatments The first study to be conducted under this project (IRB STUDY19090186) is the Strategies to Promote ResiliencY (SPRY) clinical trial (IRB PRO18060038). The SPRY clinical trial will determine the effectiveness of Metformin on improving surgical outcomes among nondiabetic older adults who are scheduled for elective surgery.
Within this project the investigators tested the effectiveness of 2-month of computerized cognitive training (CCT) on CogniFit online platform on 77 older adults, which were randomly divided into intervention and control group. The investigators tested close (battery of cognitive functions) and far transfer (postural and mobility control, EEG, blood samples) of the CCT. Additionally, the investigators were interested into seeing a long-lasting effect, therefore participants were brought back to the laboratory 1 year post CCT.
Background: 36% of the Italian population will have more than 65 years in 2050. The European Union has indicated among its priorities to increase research on active aging. Physical activity contrasts disability linked to chronic diseases, has positive effects on the quality of life and on biological rhythms, prevents the decline of motor functions, improves the immune response, and prevents / positively affects metabolic disorders. It also provides valuable support in coping with cognitive decline and memory, and acts on depressive symptomatology. The literature on active aging is based, to date, on studies with small samples, rarely conducted with a randomized controlled method, whose outcomes often appear contradictory. The multidisciplinary project the investigators propose is an opportunity to address the issues mentioned above and to acquire further knowledge in the field of active aging. Objectives: the main objective of the study is to evaluate the effects of mild-to-moderate physical activity in a sample of over-65 years-old persons, on Quality of Life, and on biomechanical parameters (static-dynamic balance, mobility). The secondary objectives are aimed at assessing whether a protocol of mild-to-moderate physical activity can improve: - Metabolic functions - Cognitive performance - Perception of pain - Social rhythms and psychological wellbeing - Inflammatory state Design: randomized controlled trial (RCT), single-blinded, with follow-up. Sample: participants will be ≥ 65 years old, of both genders, sedentary, enrolled in two arms through a random assignment (treatment/control) with ratio of 1:1, as following: - about 60 subjects who will carry out a light-to-moderate physical activity intervention (experimental group); - about 60 subjects in the control group, who will participate in group cultural activities (active comparison group). Assessment: the assessment will include socio-demographic variables; variables of psychophysical wellbeing; cognitive variables; variables related to physical health; biomechanical variables; assessment of skin integrity; lab tests on blood samples. Times of evaluations: both groups will be subjected to the measurements of the present study according to the following schedule: - T0 (baseline): before the start of the intervention - T1: 12 weeks after T0 (at the end of the intervention) - T2: after 20 weeks from T0 (follow up 1) - T3: 48 weeks after T0 (follow-up 2).
The Overall Aim of the present proposal is to evaluate the feasibility of an integrated mind-body intervention, Activate for Life, to improve overall physical activity and mental health and reduce pain and fatigue, resulting in increased likelihood of Aging in Place. Both subjective self-report (i.e., Patient-Reported Outcomes Measurement Information System PROMIS measures of pain, fatigue, depression and anxiety) and objective accelerometer data will be collected, along with standardized measures of balance, strength, and stability. In addition, the measures will be complemented with biomarker-based measures of stress, including cortisol based and 1,5-AG anhydroglucitol assays before, during, and after treatment that are correlated with stress, and fatigue symptoms.
During middle-age, humans begin to lose muscle mass and strength. With increasing age the deterioration of muscle health is associated with a decline in quality of life and the loss of independence. β-hydroxy β-methylbutyrate (HMB) plus Vitamin D (VitD) have been proposed to increase skeletal muscle mass, contractile function and improve body composition but has yet to be evaluated in middle-aged women. The overall goal of this study is to determine the effects of HMB +VitD supplementation during 12 weeks of resistance exercise training or a non-exercise control on body composition, skeletal muscle size, and skeletal muscle function in middle-aged women.
This study sought to determine if the inadequate protein intake per meal (defined as eating <30 g protein or 0.4 g protein/kg body mass) at specific meals (breakfast, lunch, dinner) is associated with functionality in middle to older aged Mexican adults. Functionality was evaluated with self-reported questionnaires to assess their functionality score for different activities of daily living.
Ageing is clearly the most important risk factor for AD and other dementias but, despite the amount of evidence supporting this fact, the exact mechanism that link ageing and AD is still unknown and, up to now, potential therapies for AD by targeting ageing have been poorly explored. This study aims to provide a better understanding of the link between ageing and AD by means of measuring in human blood those factors that have been found to be 'pro-youthful' (GDF-11, CSF2, TIMP-2, oxytocin) or 'pro-aging' (CCL2, CCL11, CCL19, Haptoglobine, B2-microglobuline) in experimental animal models, but have not been comprehensively studied in humans. In this proof-of-concept study these blood factors in extreme groups of age, namely young adults (18-25 yo) and old adults (≥70 yo) will be measured and the hypothesis of whether the 'pro-youthful' and 'pro-ageing' blood factors change throughout age tested. In order to include a wider range of age, human umbilical cord blood and plasma from teenagers (which is already available from a previous study) will also be included. The ultimate goal of this study is to select the more promising blood factors and obtain data on the effect size of the differences that may allow us in the future to design a larger study.
This study evaluates the adaptations on the functional capacity and cardiovascular in elderly after a physical activity program circuit training. The participants were divided into three groups: Circuit training based on high-intensity interval training group (HIICT), Circuit training at moderate intensity group (MICT) and Control group (CG).
