Filter by:In this study, the investigators will investigate and characterize acute medical patients in order to optimize patient courses in the acute care departments, especially with regard to polypharmacy and undernourishment. In addition, the investigators will investigate underlying immunological mechanisms of chronic inflammation and biological aging in this population to improve the current knowledge and possibilities for preventing chronic diseases and acute hospitalization.
The goal of this pilot study is to collect preliminary data on the feasibility and effect size of interventions to modify the physiological recovery trajectory from hospitalization in community dwelling older adults.
The purpose of this study is to assess the safety and efficacy of time-restricted feeding (eating within an 8-hour window) for improving physiological function (vascular, motor, cognitive and metabolic function) in healthy middle-aged and older adults.
Aside from aging, numerous factors increase the risk for developing cardiovascular disease (CVD) including diet and nutrition. High-fat meal consumption induces postprandial vascular endothelial dysfunction and other cardiometabolic disturbances (e.g. dyslipidemia and hyperglycemia) in normal weight individuals and is exacerbated in overweight/obese individuals. These postprandial responses are likely largely due to activation of pro-inflammatory and pro-oxidant pathways. Given that much of the day is spent in the postprandial state, this may further impair cardiovascular health in aging overweight/obese individuals. Interventions that attenuate these responses are needed. Red beetroot (Beta vulgaris L.) is an excellent source of bioactive compounds including nitrate, flavonoids, phenolic acids, betalains, carotenoids, and ascorbic acid. These bioactive compounds and their metabolites have been shown to have antioxidative, anti-inflammatory, and cardiovascular-protective effects. These effects, particularly the cardiovascular-protective effects, have been primarily attributed to its high content of nitrate since it is converted to nitric oxide independent of the vascular endothelium via the enterosalivary nitrate-nitrite-nitric oxide pathway. However, red beetroot juice contains a number of other potentially beneficial bioactive compounds and few studies have aimed to determine whether these compounds work independently, additively, or synergistically in exerting these effects. Given the findings of previously conducted research in the broad area of red beetroot juice consumption and human health, it can be suggested that: 1) acute red beetroot juice consumption may prevent or attenuate the adverse postprandial responses to consuming a high-fat meal in individuals with exaggerated responses; and 2) chronic consumption of red beetroot may improve underlying factors contributing to these exaggerated responses. Accordingly, this project aims to: 1) investigate the efficacy of acute and chronic whole red beetroot juice consumption compared with its bioactive components in attenuating postprandial vascular endothelial dysfunction and adverse cardiometabolic responses to a high-fat meal; and 2) to gain insight into the underlying mechanisms responsible.
The Vietnam Era Health Retrospective Observational Study (VE-HEROeS) is a national study on the health and well-being of Vietnam Veterans, including Blue Water Navy Veterans, as well as Veterans who served elsewhere during the Vietnam Era (1961-1975), and similarly aged U.S. residents who never served in the military. The investigators will invite approximately 43,000 Vietnam and Vietnam Era Veterans, and approximately 11,000 members of the general U.S. population to participate in VE-HEROeS. These individuals are scientifically selected to participate; the study is not able to accept volunteers. All participants in VE-HEROeS will be asked to fill out a questionnaire on their military service, general health, age-related conditions, health care use, and the health experiences of their children and grandchildren. A smaller group will be asked to provide the investigators with access to some of their medical records. Topics of special focus for the study include cognition, hepatitis C infection, and neurologic conditions.
Deficiency in gonadal hormone has been considered to play a role in ageing related increased incidence of cardiovascular events. But the mechanism has not been fully elucidated. On the other hand, the dramatic increase in gonadotropin level didn't drew much attention when talking about the increased risk of cardiovascular disease during menopausal transition. This study aim to investigate the association between gonadal hormone, gonadotropin and long-term cardiovascular events.
Aim of this study is to compare cardiopulmonary response to conical-PEP breathing during exercise in older people.
The accumulation and dysfunction of excess adipose (fat) tissue that occurs with ageing is associated with a number of chronic inflammatory disorders such as type 2 diabetes and cardiovascular disease but the underlying mechanisms are not understood.
Understanding the complexity of aging and frailty in chronic HIV infection motivated Italian team members to begin to build a frailty index (FI) including 37 health variables at the Modena HIV Metabolic Clinic (MHMC). The validation of FI in HIV patients have been recently published, and more data comparing FI in HIV infected vs un-infected people, have been presented at international meeting and are at present submitted for publication. The research consortium (MHMC, HCC and HHMP) of this study was motivated to begin preliminary work in consideration of the similar multidisciplinary approach in Ageing care and capacity to address health status in ageing HIV patients using shared definitions of co-morbidities, multi-morbidity and measures of Physical Function and Cognition impairment, disability and quality of life. The investigators wanted to overcome the major criticism intrinsic in the FI, that is the needs to collects many variables not easily available in most HIV centres. The the investigators approach is to make patient living with HIV (PLWH), be the source of health variables taking advantage of information and communication technologies available with smart phones and fitness tracking device, collecting physiological parameters and patient related outcomes.
The Helsinki Businessmen Study (HBS) is a clinico-epidemiological longitudinal study started in 1964. It also included a 5-year randomized, controlled multifactorial primary prevention trial of cardiovascular diseases between 1974-1980. The cohort is being actively followed-up through national registers since the 1980, and since 2000 with regular questionnaire surveys. Latest in 2015. Also clinical and laboratory studies have been performed in random subcohorts. Follow-up is ongoing with new hypothesis-generating research questions.
