Filter by:Non-communicable diseases (NCDs) compose a substantial proportion of the global burden of diseases, posing a significant challenge in both high-income and low- and middle-income countries. In particular, certain lifestyle-related risk factors, such as unhealthy diet, physical inactivity, smoking, excessive alcohol consumption, and sleep deprivation are the leading risk factors, which place people at an increased risk of developing NCDs. On the other hand, a growing phenomenon of excessive concern about diet and health is emerging, and it is contributing to the development of a novel eating behavior disorder named orthorexia nervosa. According to recent studies, orthorexic behavior is very common among young adults and especially so in health-care professionals. The main objective of this multi-center study is to explore and compare lifestyle habits among undergraduate medical students and other healthcare-related professions from different countries (Croatia, Lebanon, Italy, Poland, Spain, and Turkey). The goal is to obtain information on the presence of unhealthy habits in order to be able to intervene, offering the information needed for primordial disease prevention in this young and still healthy group of respondents, who are the health educators and role models of the future. The particular importance of this goal is to raise awareness of the problem of the ubiquitously present unhealthy lifestyles. Unfortunately, health-care students are not the exception regarding the prevalence of the unhealthy diet, sedentary behavior, sleep deprivation and high levels of psychological stress. Furthermore, the adoption of unhealthy lifestyle patterns in health-care workers, such as doctors and nurses, will have far-reaching negative consequences, in both their health and their patients' health. The results of this study will be used for identifying the needs and targets for intervention, enabling students to become a pillar of health education for their patients and the population in general.
There are experimental evidences of the important role of high intensity physical exercise in Parkinson's disease (PD) treatment, that induces similar effects to pharmacotherapy. So far, the mechanisms of the impact of these changes on the brain subcortical and cortical regions functioning, motor activities and cognitive functions are still not clear. The aim of this longitudinal (prospective) human experiment is to examine the effects of two cycles of 12-weeks high-intensity interval training (HIIT) on: (i) the level of dopamine (DA) in putamen in striatum, (ii) neurophysiological function of subcortical and cortical motor structures and skeletal muscle activity, (iii) psychomotor behaviors critically associated with dopamine dependent neural structures functioning and (iv) neurotrophic factors' secretion level in blood. The investigators will recruit 40 PD individuals, who will be divided into two groups: one of them will perform two 12-weeks cycles of HIIT (PD-TR), and the other will not be trained (PD-NTR) with HIIT. The investigators will also recruit 20 age-matched healthy controls (H-CO) as additional control group who will not perform the HIIT. The PD-TR group will perform the two 12-weeks cycles of the HIIT, that induces beneficial, neuroplastic changes and alleviates the PD symptoms, what was found in earlier studies. All PD subjects (PD-TR and PD-NTR) will be examined during their medication "OFF-phase" (it means after dopaminergic drugs withdrawal) before (Pre) and after (Post) training cycles (first training cycle - HIIT 1; second training cycle - HIIT 2), and namely: Pre HIIT 1, 1 week-, 1.5 month- and 3 months-Post HIIT 1; and then similarly 1 week-, 1.5 month- and 3 months-Post HIIT 2. The subject from H-CO will be tested only once. To examine the assumed HIIT-induced changes in brain functioning the investigators will apply: (i) the positron emission tomography (PET), (ii) the functional magnetic resonance imaging (fMRI), (iii) electroencephalography (EEG) and (iv) an analysis of neurotrophic factors secretion level in blood. The investigators will also assess motor and non-motor symptoms of PD and psychomotor behaviors based on neuropsychological tests of cognitive functions and manual dexterity. The results of this project will help to answer the fundamental questions about HIIT induced mechanisms of neuroplasticity in PD patients, what is important from scientific and treatment-strategy point of view.
The purpose of this study is to evaluate the effectiveness of a recreational physical activity intervention for reducing the prevalence of overweight/obesity and other cardiovascular risk factors
The goal of the Molecular Transducers of Physical Activity Consortium (MoTrPAC) is to assess molecular changes that occur in response to physical activity (PA). To achieve this aim, studies will be conducted in adults and separately in children and adolescents. The UC Irvine MoTrPAC Pediatric Clinical Center oversees two interrelated study phases in children and adolescents: 1. A cross-sectional phase in which molecular transducers (obtained from blood sampling) are measured in response to an acute exercise challenge (n = 320); 2. An intervention phase is conducted as a mechanistic randomized controlled trial (RCT). Participants are recruited from the cross-sectional study phase and randomized to endurance exercise (EE) training (n = 120) or no exercise Control (n = 50) for a period of approximately 12 weeks.
Fibromyalgia affects 2 to 5% of adults in the general population. Patients describe a combination of symptoms centred around fatigue not induced by exercise and not relieved by rest. The diagnosis of fibromyalgia is self-perpetuating by the deconditioning, consequence of a reduced muscle mass due to inactivity and periods of prolonged rest. Thus, it seems fundamental to develop other non-drug approaches: among them, adapted physical activity is recommended by most learned societies because of a good level of evidence (Level 1, Grade A). The question remains, however, whether simple advice to resume physical activity is sufficient (routine care with medical assessment at 3 months) or whether a physical activity supervised inside and outside the hospital is not more relevant.
The project focuses on supporting home care in the post-hospitalization period (Home Health Phase), and then further optimizing the older Veterans' recovery of mobility and physical activity in the transition back to the home/community (Follow-up Phase).
Treatment for people with cancer of the lung or the oesophagus (food-pipe) often involves surgery. This surgery is complex and there is a high risk that patients will develop severe complications afterwards, leading to a longer hospital stay and higher hospital costs, and impacting greatly on recovery and quality of life. If patients' lungs and heart can be optimised before surgery, then recovery may be improved. While fitness can be improved by exercise, the lead-in time to surgery following a cancer diagnosis is often very short, and research is needed to examine what types of exercise might be most effective at increasing fitness over a short period. This project will investigate if high intensity interval training (HIIT) can increase fitness levels in people scheduled for surgery for cancer of the oesophagus or the lungs. HIIT alternates between periods of high intensity exercise, cycling on a stationary bike, followed by a period of more relaxed exercise. This approach is known to improve fitness but has not previously been investigated in patients awaiting complex cancer surgery. Groups will be compared for changes in pre-surgery fitness levels, any complications they may experience after surgery, general physical recovery after surgery and the cost of care after surgery. The investigators anticipate that patients who undergo HIIT before surgery will have less complications and better recovery after surgery, a significantly improved quality of life, and lower costs of care.
The goal of the Molecular Transducers of Physical Activity Consortium (MoTrPAC) is to assess molecular changes that occur in response to physical activity (PA). To achieve this aim, a mechanistic randomized controlled trial (RCT) is conducted, in which adult study participants are randomized to endurance exercise (EE) training, resistance exercise (RE) training, or no exercise Control for a period of approximately 12 weeks. The overarching hypothesis is that there are discoverable molecular transducers that communicate and coordinate the effects of exercise on cells, tissues, and organs, which may initiate processes ultimately leading to the health benefits of exercise. Because this is a mechanistic trial, the main goal is not a single health-related outcome. Rather, the goal is to generate a resource leading to the generation of a map of the molecular responses to exercise that will be used by the Consortium and by the scientific community at large to generate hypotheses for future investigations of the health benefits of PA.
Physical exercises program is known to improve quality of life, chronical fatigue and appears to be a behavioural recommendation against cancer as primary and tertiary prevention. Nutritional status is also important in cancer patients: a loss of 5% of weight increases the complication risks and decreases survival and the quality of life. Interactions between physical activity and haematological malignancies are less described compared to solid cancers. Methodology and protocols are also heterogeneous. Supervised exercises program improves the physical condition and the quality of life; however there are few randomised studies versus a controlled group. Post autograft evaluation for myeloma patients showed a physical deficit with increased fat mass, but in this particular population physical exercises need to be more explored. This project is a randomised study versus controlled group that evaluates supervised physical exercises program in a homogenous population: patients under-65-years-old with multiple myeloma and who will undergo autologous stem cell transplantation.
An unacceptably high percentage of our nation's low-income, minority youth (< 18 years of age) are not regularly physically active. This contributes to extreme health disparities such as obesity rates nearly two-fold higher than those seen in white youth and greater risk for diabetes and related cardiometabolic disorders. The presence of quality youth physical activity opportunities (YPAO) enables and encourages physically active lifestyles. Unfortunately, quality YPAOs often are lacking in places where minority youth live, resulting in low activity levels and subsequent health issues that represent significant disparities in our society. The investigators' previous research found that small businesses (< 500 employees), which represent over 99% of all employers, are powerful resources for creating and improving YPAOs. In accordance with the Socioecological Model and established philanthropic principles, the investigators developed an alpha version of an intervention (alpha-i) for increasing small businesses' involvement with YPAOs. The investigators are now poised to create a beta version (beta-i) and conduct a pilot study of its impact on small business support for YPAOs and YPAO utilization by youth in low-income, minority neighborhoods. To meet this objective, the investigators will complete the following specific aims. Aim 1: Refine alpha-i components by completing focus groups with small business owners, YPAO providers, and parents/guardians of youth from low-income, predominantly minority neighborhoods. Results of the qualitative analysis will inform final tailoring of the intervention to create the beta-i which will be tested in Aim 2. Aim 2: Determine the effect of the beta-i on small business support for YPAOs in low-income, minority neighborhoods by conducting a plot cluster randomized-control trial with randomization at the neighborhood level. Intervention neighborhoods (n=10) will receive the beta-i while control neighborhoods (n=10) will be provided a standard practice intervention for a period of one year. The primary outcome for aim 2 will be the percentage of small businesses not supporting YPAOs at baseline that subsequently provide support for YPAOs at follow-up. The investigators also will consider the U.S. dollar equivalent of all types of support (monetary, goods/services and time) donated for YPAOs by small businesses. Aim 3: Examine the impact of the increased small business support for YPAOs on YPAO utilization by youth. The primary outcome will be the percent change in the number of youth participating in YPAOs from baseline and follow-up in the treatment and control neighborhoods. The proposed study is significant because it will provide evidence that an easily replicated approach can be used to increase small business support for YPAOs and that this support results in greater use of the YPAOs by youth. The investigators' next step will be to determine if YPAO changes resulting from increased small business support positively influence youth physical activity levels as measured by accelerometry. The investigators long-term goals are to create a nationally implementable practice for increasing support for YPAOs and strengthen the science of addressing health disparities in socially disadvantaged populations.
