Leg Heating in Pregnant Women With Obesity

Obesity is a major risk factor for hypertensive disorders of pregnancy (HDP). The underlying mechanisms are largely unclear, but maternal vascular endothelial dysfunction is likely involved. Endothelial dysfunction in HDP could be attributed to 1) alterations in the L-arginine/nitric oxide (NO) pathway, and 2) an increase in endothelin-1 (ET-1). Additionally, augmented sympathetic vasoconstriction may also contribute to HDP. Chronic (repeated) whole-body heat exposure has been shown to increase NO bioavailability, decrease ET-1, and cause functional and structural adaptations in the vasculature. All these can improve vascular function, attenuate sympathetic (re)activity, lower blood pressure (BP), and reduce cardiovascular risk in non-pregnant individuals. Whether this is also true after regional (leg) heating in high-risk pregnant women is unknown. The investigators' central hypothesis is that chronic leg heating will be effective in improving vascular endothelial function and attenuating sympathetic vasoconstriction, leading to a reduction of the risk for HDP in pregnant women with obesity. The overarching goal of this proposal is to determine the vascular and neural effects of chronic leg heating in obese pregnancy. The study team plans to enroll pregnant women with obesity between 12-14 weeks of gestation and randomly assign them to either an intervention group or a control group (1:1 ratio). Participants in the intervention group will perform 16 weeks of home-based leg heating using a portable sauna blanket up to the hip (temperature of the blanket will be set at 65°C, 4 times/week, 45 min/session), whereas women in the control group will set the temperature of the blanket at 35°C at the same frequency and duration. Participants will be evaluated at baseline and then at 28-30 weeks of gestation. Aim 1 will determine the effects of chronic leg heating on maternal vascular function and surrogate markers of HDP. Aim 2 will determine the effects of chronic leg heating on sympathetic vasoconstriction and BP. Findings from this project will provide insight on the extent and potential mechanisms of how chronic leg heating works for improving vascular endothelial function and sympathetic vasoconstriction in pregnant women with obesity. Results obtained will set a foundation for future large multicenter clinical trials to determine the efficacy and generalizability of home-based leg heat therapy as a safe, ease-of-use, cost-effective, and non-drug approach for reducing the risk of HDP.

The goal of this clinical trial is to test whether an adaptation of an evidence-based, couple-based preventive intervention at the transition to parenthood improves reduces obesity risk among infants and parents in military families via improved interparental support and coordination around health lifestyle behaviors and parenting. The main question it aims to answer is whether an adapted, innovative family-focused approach to obesity prevention can reduce rapid infant weight gain, new mothers' postpartum weight retention, and fathers' weight status. Participants randomized to the Healthy Family Foundations (HFF) intervention condition will participate in 10 online group classes (5 prenatal and 5 postnatal). Participants randomized to the control condition will receive standard of care and opportunities for education at their site. Researchers will compare the Healthy Family Foundations (HFF) intervention group with a Standard of Care control group to see if there are differences in weight, coparenting support, parent mental health and parent health behaviors.

Background: - Like other complex diseases, autoimmune diseases are the result of numerous causes, including genetic and environmental factors. Some researchers believe that people who are susceptible to autoimmune disorders develop them when the body reacts to environmental or other factors by creating white blood cells that attack the body s own tissues, which then progresses to autoimmune diseases. These immune-triggered disorders can overlap with one another to some extent, but most autoimmune diseases have certain distinct triggers. - The autoimmune disorder myositis weakens the muscles and may cause other health problems. Environmental exposures associated with myositis include ultraviolet radiation, stressful life events and muscle overexertion, collagen implants, infections such as retroviruses and streptococci bacteria, and certain drugs and chemicals. Some individuals with myositis also produce proteins in the blood called autoantibodies that react with certain parts of the person s own cells, called synthetases, which are involved in making new proteins. A syndrome called the anti-synthetase syndrome, which includes myositis and lung disease, is associated with having the anti-synthetase autoantibodies. Researchers are interested in studying differences in environmental exposures in individuals with myositis. This study is being conducted to determine if persons with the anti-synthetase syndrome have had different environmental exposures before disease onset compared with other patients with myositis who do not have this syndrome and also compared with healthy volunteers. Objectives: - To determine whether selected infectious and noninfectious environmental exposures are more common in individuals who have myositis with the anti-synthetase syndrome, compared with healthy volunteers. Eligibility: - Individuals who have been diagnosed with myositis (with or without anti-synthetase autoantibodies), and healthy volunteers without autoimmune disorders. Design: - Participants will be screened with a full medical history and physical examination, and will provide blood, urine and house dust samples. - Participants will complete questionnaires about their medical history and the types of exposures they have had at work, at home, and elsewhere. Participants who have myositis will also be asked about certain infections, heavy exercise or physical exertion, sun exposure, tobacco and alcohol use, and stressful events prior to being diagnosed with the disease. Healthy volunteers will be asked about the same exposures before the date of diagnosis of disease of the myositis subject to which they have been matched. - Participants will receive a kit that contains instructions and a filter to be put onto their vacuum cleaner to collect house dust in the bedroom. This dust will be kept for possible future analyses of infectious or toxic agents based on the other results from the study. - Individuals with myositis will have other tests as clinically indicated, including lung function tests and imaging studies.

There is evidence that early and aggressive treatment with antiretroviral drugs can prevent the loss of immune cell function that accompanies HIV infection. This study will use leukapheresis (drawing blood, separating out the white cells and returning the blood to the patient) to obtain blood cells from HIV-infected patients in either the acute or chronic stage of infection who are being treated with early highly active antiretroviral therapy (HAART). Leukapheresis is necessary to obtain enough cells to delineate the response of B cells to CD4+ T cell help, the CD8 factors associated with suppression of viral replication and normalization of immune function, and natural killer function relative to HIV disease. Study participants will be adult (older than 18 years) HIV primary or acutely affected patients (those with a history of exposure to HIV but not yet showing chronic symptoms of HIV disease) and HIV chronically infected patients (those infected with HIV for longer than 12 months or showing other symptoms of HIV disease) who are not receiving HAART at the beginning of the study. The study seeks to enroll 30 primary and 30 chronic patients. Pregnant women will not be enrolled in the study; women who become pregnant will be dropped from the study. Leukapheresis will be performed on each patient before HAART therapy begins and then three times a year. Each session will take between 1 and 3 hours. This longitudinal study will enable researchers to examine the function of certain B cells, natural killer cells, and CD8+ T cells in people who do not have chronic HIV disease and in those who do have the disease and are treated with HAART.

Laboratory tests may include routing blood and urine tests, X-rays, or other imaging studies, body fluid or tissue cultures, skin biopsy and tests for allergic or immune responses. Treatment will include only medications approved by the Food and Drug Administration, given according to accepted dose schedules and ways of taking the medicines. All diagnostic tests and treatments will be according to standard medical practice for the disease. No experimental procedures will be offered under this protocol. Patients will be followed as needed for evaluation and treatment of their condition. In general, they will be asked to return at the end of therapy, then 3, 6 and 12 months later, and then every 6 to 12 months. More frequent visits may be required or less frequent visits may be allowed, depending on the individual s condition. Participants may be asked to undergo the following additional procedures for research purposes: - Extra blood draws to study Lyme disease and other inflammatory conditions. Blood will be drawn from arm veins. The total amount drawn during any 6-week period will not exceed 450 cc (30 tablespoons) for adults and 7 cc (1/2 tablespoon) per kilogram (2.2 pounds) of body weight for children under 18 years of age. - Leukapheresis to collect large numbers of white blood cells. Whole blood is collected through a needle in an arm vein, similar to donating blood. The blood circulates through a machine that separates it into its components, and the white cells are removed. The rest of the blood is returned to the body through the same needle. Only adults 18 years of age and older will be asked to undergo leukapheresis. Type: Observational Start Date: Jan 2002 |

The investigators are conducting a 10-week brain imaging and medication study. They are doing the research to study the response of Attention-Deficit/ Hyperactivity Disorder (ADHD) in youth with Autism Spectrum Disorder (ASD) on extended-release formulation of mixed amphetamine salts (MAS) (also know as Adderall XR). The investigators also want to find out if taking MAS has any effect on the brains of children and adolescents with ADHD and ASD. This study will help researchers better understand how the use of MAS to treat ADHD effects children and adolescents with ASD. The investigators will compare MAS to a placebo. The placebo will look exactly like the MAS capsules but will contain no MAS. During this study, participants may get a placebo instead of MAS. Placebos are used in research studies to see if the study results are due to the study drug or due to other reasons. Participants with ASD and ADHD will complete 4-weeks of treatment with the study medication or placebo. They will complete bi-weekly study visits virtually via a telemedicine platform with the study doctor and complete questionnaires. On alternating weeks, they will meet with a Massachusetts General Hospital (MGH) study team member to discuss medication adherence and potential side effects. Participants will have the option to attend all study visits in-person if participants prefer. They will also complete baseline and endpoint Magnetic Resonance (MR) scan visits at Massachusetts Institute of Technology (MIT). During the MR Scan visits, they will complete a series of tasks to measure inattention, impulsivity, reward sensitivity, decision-making, and working memory. Participants without ADHD or ASD will complete eligibility screening with MGH. If eligible, they will be invited to baseline and endpoint MR scan visits at MIT.

This study investigates the relationship between the noradrenergic (NA) system, sleep quality, and cognitive function in older adults with insomnia - a population at elevated risk for Alzheimer's disease-related dementias (ADRD) - compared to age and sex matched controls with normal sleep. The study characterizes NA function through multiple approaches: measuring 24-hour plasma levels of norepinephrine (NE) and its brain metabolite 3-methoxy-4-hydroxyphenylglycol (MHPG); evaluating central NA system response using the clonidine suppression test (a presynaptic α2 adrenoreceptor agonist that reduces locus coeruleus NA activity; and employing pupillometry as a non-invasive marker of autonomic function. To explore NA function's mechanistic role in insomnia, the study uses an intervention with bright light exposure to enhance daytime NA activity, with the goal of improving both sleep quality and cognitive performance.

Children and adults with pulmonary arterial hypertension (PAH) have severely reduced daily activity compared to healthy populations. In adults, investigators recently demonstrated that lower baseline daily step counts associated with increased risk of hospitalization and worsening WHO functional class; similarly, reduced step counts associate with hospitalization in children with PAH. This application builds on our recently completed NIH-funded pilot mobile health (mHealth) trial in adult patients with PAH which demonstrated the ability to remotely increase step counts. The investigators now aim to: (1) adapt our mHealth intervention to the developmental needs and interests of adolescents; and, (2) determine if our intervention increases step counts in adolescents, providing the foundation for a larger trial to assess the impact on quality of life and clinical outcomes.

This study will compare the effects on cardiorespiratory fitness (CRF) of aerobic exercise in different amounts (number of minutes/session) over different periods of time (number of weeks). Aerobic exercise is physical activity of light-to-moderate intensity that uses the large muscle groups (muscles in your legs, buttocks, back, and chest) and can be performed for at least 10 minutes. The researchers will study the effects of different exercise programs on how well the study participants' bodies use oxygen, how well their heart pumps blood, how well their lungs function, and how healthy their blood vessels are.

Background: Blood disorders like sickle cell disease and malaria affect many people around the world. Researchers want to learn more about blood disorders. To do this, they need to collect biological samples from people with blood disorders. They also need to collect samples from healthy people. Objective: To collect samples to use for research on blood disorders. Eligibility: People ages 18-70 who have blood disorders. Healthy volunteers without blood disorders are also needed. Design: Participants will be screened with a medical history, physical exam, and blood and urine tests. Participants will give one or more samples. They will give them over 5 years. They can choose not to give any of the samples: Saliva: Participants will spit into a tube. They may also have the inside of their mouth swabbed. Urine: Participants will urinate into a cup. Blood and blood waste products: Blood will be taken through a needle in the participant s arm. Fat samples: An area on the participant s belly or buttock will be numbed. A small cut will be made into the skin and a small piece of fat removed. Mucus and cells from the lungs: The participant will be sedated. A flexible tube will be inserted through the nose or mouth into the lung airways. These participants will also have a physical exam, chest x-ray, and heart tests after the procedure.

Background: An electroencephalogram (EEG) measures the brain s electrical activity. EEG shows that the louder the sound needed to wake a person, the deeper the person s sleep. Researchers are using functional magnetic resonance imaging (fMRI) to study people during sleep so they can view brain activity in 3D. But they still need to correlate fMRI with sound thresholds, like the EEG. Objective: To measure brain activity during sleep using fMRI and EEG. Eligibility: Healthy people ages 18 34 who can sleep on their back for several hours. Design: Participants will be screened online about their sleep and general health. At a screening visit, participants will have: Physical exam Hearing exam MRI scan. A strong magnetic field and radio waves take pictures of the brain. Participants will lie down on a bed that slides into the scanner, which is shaped like a cylinder. Participants will wear an actigraph on their wrist that records their motor activity. Participants will follow a 2-week routine. This includes regular in-to-bed and out-of-bed times and limits on alcohol, caffeine, and nicotine. During the overnight visits, participants will have: Female subjects will have a urine pregnancy test. fMRI. A coil will be placed over the head. Participants will do tasks shown on a computer screen inside the scanner. EEG. Small electrodes on the scalp will record brain waves while sleeping or doing a task in the scanner. Participants will be asked to try to sleep while researchers collect fMRI and EEG data. Participants eyes will be monitored with a video camera. Headphones will deliver sounds to wake them up throughout the night. ... Type: Observational Start Date: Jan 2016 |
