Active clinical trials for "Fatigue"

Firefighters work some of the most demanding schedules known under highly stressful and demanding conditions. The need to work frequent extended shifts and long work weeks leads to acute and chronic partial sleep deprivation as well as misalignment of circadian phase. Sleep disorders are common, costly, and treatable, but often remain undiagnosed and untreated and it is likely that a significant proportion of firefighters suffer from undiagnosed sleep disorders which will further impair their sleep and exacerbate fatigue.In the current proposal, we aim to address the health, performance and safety issues related to fatigue in firefighters and test the effectiveness of a Comprehensive Firefighter Fatigue Management Program (CFFMP) that we have termed 'Operation Healthy Sleep.'

The purpose of this study is to determine if the Forsus Fatigue resistant Device appliance with direct skeletal mini plates anchorage is capable of achievement of skeletal mandibular effects while preventing the excessive proclination of the lower incisors at the end of the treatment when compared to the conventional Forsus Fatigue resistant Device appliance applied to the upper and lower dental arches in female patients with skeletal Class II malocclusion

Cancer-related fatigue (CRF) is a major problem in children, adolescents and adults receiving treatment for cancer, and intensively treated patients may be at higher risk. While exercise is an effective intervention for CRF, patients receiving the most intensive chemotherapy may frequently be too ill to participate in a standardized exercise program. A unique intervention that combines exercise and relaxation is yoga. This pilot study will evaluate the feasibility of three times weekly yoga sessions administered by a trained yoga instructor for a three week duration and will enroll between 10 and 20 children. If feasible, the intervention will be tested in a randomized controlled trial.

Acute exposure of the unacclimatized human body to high altitude leads to health complications, such as loss of exercise performance capacity and fatigue. The investigators have found that the combination of the xanthine drug theophylline and the endothelin receptor antagonist ambrisentan improves the exercise performance capacity of rats under simulated high altitude. In young, healthy human volunteers, this combination of drugs has not increase toxicity over the single compounds under sea-level conditions. The aim of this study is to test whether the combination of theophylline, supplied as its more soluble formulation aminophylline, and ambrisentan, are also safe to take under simulated high altitude of 4,267 meters, under both resting and exercising conditions. The study also aims to test whether this drug combination improves exercise capacity in humans. In this study, human subjects will be randomized to one of four treatment sequences and receive the same study drug(s) throughout all procedures. The study consists of an initial exercise test, followed by two cycles of drug testing at simulated high altitude: Cycle 1 - resting subjects receiving study drug at simulated altitude and continually monitored for safety with pharmacodynamic and pharmacokinetic assessments; and Cycle 2, the same as Cycle 1, with the addition of exercise testing. It is hypothesized that the combination of aminophylline and ambrisentan is not only safe under simulated high altitude, but also improves exercise performance capacity, in comparison with placebo.

The purpose of this study is to determine whether American ginseng is effective in the treatment of HIV-associated fatigue.

The purpose of this study is to determine any sleep disordered breathing in veterans with Gulf War Syndrome (GWS) and compare it to healthy normal asymptomatic Gulf War veterans. This study will also determine the effect of treatment with continuous positive airway pressure on veterans with Gulf War Syndrome. The investigators hypothesize that sleep complaints (insomnia, un-refreshing sleep and daytime fatigue) among GWS patients are related to increased sleep fragmentation secondary to the presence of sleep disordered breathing in GWS patients. The investigators hypothesize that increased collapsibility of the upper airway during sleep with the development of inspiratory flow limitation (IFL) and sleep disordered breathing causes the increased sleep fragmentation in GWS patients. The investigators hypothesize that correction of IFL and sleep disordered breathing in GWS patients will result in an improvement of their sleep quality resulting in an improvement of their sleep complaints and other functional symptoms.

The purpose of this study is to develop methods for studying the effect of bodywork therapy on symptoms of fatigue in patients undergoing cancer chemotherapy.

L-carnitine is a supplement (type of vitamin) that has been suggested to be decreased in patients with cancer. We will identify patients that have terminal cancer and fatigue. The purpose of this study is to determine if L-carnitine replacement improves fatigue in cancer patients with L-carnitine deficiency.

Telerehabilitation is a great alternative to offering care during a global pandemic. 85% of patients with COVID-19 report persistent symptoms up to 8 months after the infection. There are no clear recommendations for post-covid rehabilitation. The aims of the study are (1) to test the logistic aspect of implanting a hybrid rehabilitation program and (2) to evaluate the acceptability and the potential impact of the program on treating patients with functional limitations and persistent fatigue symptoms. It's a pre and post-study without a control group.

Many patients receiving radiation therapy for breast cancer experience fatigue although doctors do not fully understand why. The purpose of this study is to test if patients who experience fatigue during radiation treatment for breast cancer have changes in their capability to perform exercise on a treadmill.
