Physical Rehabilitation in Sickle Cell Anemia

Sickle cell anemia (SCA) is one of the most neglected diseases worldwide, according to the World Health Organization. In the adult population with SCA, the systemic effects of the disease, such as respiratory and peripheral muscle dysfunction, cause a decrease in quality of life. As a consequence, there is a concern about functional rehabilitation, since the aging of this population is already a reality in our environment. Thus, the objective of this project is to evaluate the effects of functional rehabilitation on quality of life in adult patients over 18 years of SCA. In this longitudinal intervention study, patients will be submitted to a three-month rehabilitation program. Before and after the intervention, patients will be submitted to the following assessments: spirometry; quality of life questionnaire - Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36); functional scale of joint integrity - Lower Extremity Functional Scale (LEFS); fatigue assessment scale - Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F); physical activity assessment questionnaire - International Physical Activity Questionaire (IPAQ); peripheral muscle assessment (handgrip and isometric dynamometry of the quadriceps muscle); and 6-minute walk test (6MWT). The protocol will consist of warm-up and cool-down exercises, muscle strengthening and endurance exercises, aerobic training, balance training and proprioception. Thus, it is expected that patients with sickle cell anemia will benefit significantly, with a consequent improvement in musculoskeletal function, pain and health-related quality of life.

New Technologies as a Tool for Health Promotion in Schoolchildren of Compulsory Secondary Education

The rapid development of new technologies could be one of the causes that has favored changes in the lifestyle habits of young people. Research carried out to date shows that new technologies could be useful in increasing levels of physical activity and motivation to practice sports. However, these studies have major limitations that make it difficult to generalize the results. The objectives of the present project are: 1) to determine the influence of the use of new technologies on the levels of sports practice and the physical and psychological health of adolescents; 2) to analyze the effects of a physical-sports activity program that integrates new technologies through mobile applications related to physical exercise on the level of physical activity and the physical and psychological health of adolescents; and 3) to analyze the adherence that this type of program generates in the medium term in adolescents as a function of age and gender. The project will be divided into two phases. In the first phase, 500 students from the centers of Compulsory Secondary Education will be included, who will undergo physical tests, questionnaires related to sports practice and physical and psychological health, and an anthropometric assessment. In the second phase, an intervention will be carried out with four experimental groups and a control group. The four experimental groups will use different technological applications outside school hours for 12 weeks. Participants will keep a weekly record of physical activity and pre-, post and re-test measurements will be taken to evaluate the efficacy of the sports technology applications in increasing and maintaining physical activity.

Testing Scalable, IVR-supported Cancer Prevention Interventions in the Rural Alabama Black Belt

This protocol involves a randomized controlled trial (N=240) to test the efficacy of the Deep south Active Lifestyle (DIAL intervention) telephone-based physical activity counseling intervention vs. a wait list condition. Assessments of MVPA and psychosocial variables will occur at baseline, 6, 12, and 18 months. Primary aim. Test the efficacy of DIAL intervention vs. wait list control. Hypotheses are that the participants receiving DIAL intervention will report significantly greater increases in MVPA (based on 7-Day Physical Activity Recalls, accelerometers) from baseline to 6 and 12 months than the wait list control arm. Exploratory Aims. Examine 1) Intervention effects on physical performance and psychosocial variables (anxiety, depression, fatigue, sleep disturbance; corroborate self report sleep improvements from pilot with accelerometry); 2) Changes in MVPA from 12-18 months to assess long term (6 months post-intervention) maintenance in the intervention arm and ascertain replicability of intervention effects in wait list control arm; 3) Intervention costs; 4) Potential mediators (social support from family, friends, CHAs, theoretical constructs directly targeted by the intervention) and moderators (education, neighborhood/environmental features) of treatment efficacy; 5) Potential barriers/ facilitators to widespread implementation of DIAL intervention in rural Black belt counties by Deep South Network for Cancer Control. This proposal tests an intervention which acts on multiple levels of the socio-ecological model and uses IVR technology to enhance the potential for scaling and sustainability for broad use in populations at high risk for sedentary behavior (residents of rural Black counties in the Deep South).

Biologic Mechanisms for Pain Variation After Physical Activity in Osteoarthritis

Osteoarthritis (OA) in the knee is characterized by chronic inflammatory pain that is not necessarily related to the amount of joint damage. Clinical practice guidelines recommend physical activity (PA) for osteoarthritis pain, but most adults with OA do not engage in PA. One reason for this is that while PA can reduce OA related joint pain, it does not work for everyone. PA decreases pain sensitivity for about half of adults with OA but increases pain sensitivity for the other half. The investigators are hypothesizing that individual differences in how well cells work to make energy, inflammation, and different proteins available in blood cells explains who PA will work to reduce pain and who it won't among adults with OA. The purpose of this pilot study is to determine if blood cells' ability to make cellular energy, inflammation and proteins help explain the difference about who PA reduces activity for and who it doesn't. The investigators will compare these biologic factors and pain sensitivity before walking, immediately after 30 minutes of walking (i.e. "acute") and after six weeks of walking three times a week for 30 minutes (i.e. "long-term") in adults with hip or knee osteoarthritis. The investigators will also compare these results to adults without OA. The investigators will recruit a sample of 40 adults with radiologic (e.g x-ray or CT scan) evidence of hip or knee OA and 20 age/gender matched healthy adults without OA to address the following study aims: Aim 1: To examine the effects of a six week (three days/week) walking program on pain in adults with OA as compared to healthy controls. Aim 2: To test the cells' ability to make energy as a mechanism for variation in pain after "acute" and "long-term" PA in older adults with lower extremity osteoarthritis. Aim3: To test the role of inflammation as a mechanism for variation in pain after "acute" and "long-term" physical activity in adults with lower extremity osteoarthritis. Aim 4: To generate hypotheses regarding the role of proteomics in variation in pain after "acute" and "long-term" physical activity.

Supervised Resistance TRaining amONG Women at Risk of Breast Cancer Related Lymphedema

Breast cancer (BC) is the most common neoplasm in Chile, and its medical treatment leads to high survival. One-third of survivors will develop BC-related lymphedema. Lymphedema is a chronic condition characterized by increased volume in the ipsilateral arm to surgery. A higher volume is associated with decreased physical functionality and quality of life. Recent studies suggest that resistance training could control arm volume through increased muscle mass development, improving physical functionality and quality of life for patients. To our knowledge, there is no study that has analyzed the effect of a resistance training program among women at risk of BC-related lymphedema on quality of life. The purpose of this study is to determine the effect of resistance training on the quality of life among women with adjuvant chemotherapy and high risk of BC-related lymphedema compared to a control group with regular physical therapy management, which does not include resistance training. This is a randomized controlled study. It will be held at the Complejo Asistencial Dr. Sotero del Río, which receives all patients from the South East Metropolitan Health Service. Participants: 116 women receiving adjuvant chemotherapy for BC who have undergone axillary lymph node dissection or with obesity will be recruited. Quality of life will be evaluated with The European Organization for Research and Treatment in Cancer Quality of Life C-30 (EORTC QLQ C30) questionnaire, validated in Chile; the difference in volume between the arms with optoelectric equipment; physical functionality with the six-minute walk test; and the handgrip with a dynamometer. Volunteers will be randomly assigned to the resistance training group or control group. The resistance training group will consist of twice a week supervised sessions, for 12 weeks. The exercises will be for arms and legs, self-loading type, and with external weights. The control group will follow the usual physical therapy management, which does not include resistance training. Subsequently, volunteers will be evaluated at the third and sixth months after completion of the 12 weeks resistance training program.
