A Study to Evaluate IPN10200 Safety and Efficacy in the Prevention of Episodic or Chronic Migraine in Adults
NCT06625060
Recruiting
A migraine is a headache with severe throbbing pain or a pulsating sensation, usually on one side of the head. It is often accompanied by feeling or being sick and a sensitivity to bright lights and sound. Migraines are caused by a series of events when the brain gets stimulated or activated, which causes the release of chemicals that cause pain. IPN10200 is a medication that stops the release of these chemical messengers. Participants with episodic migraine (EM) or chronic migraine (CM) will b... Read More

Diet and Microbiome Interactions: Application in Posttraumatic Stress Disorder in Adults Consuming Vegetable Drinks
NCT07107269
Recruiting
The gut microbiome has been shown to impact various facets of human health, including mental health. Studies have shown that populations with more agrarian lifestyles tend to have fewer chronic diseases and mental health issues than industrialized populations. A possible factor in these differences is the loss of co-evolved gut microbial taxa that has occurred with Westernization. This hypothesis, termed "Old Friends Hypothesis" suggests that the loss of certain gut microbes leads to immune dysr... Read More

A Study of Imlunestrant Versus Standard Endocrine Therapy in Participants With Early Breast Cancer
NCT05514054

Influence of Short-Term Antibiotic Therapy on Exercise
NCT05961189
Recruiting
The gut microbiome refers to the trillions of bacteria that inhabit the stomach and other regions involved in the digestion of food, including the intestines. Compelling studies of animals (rodents) suggest that the health of the gut microbiome may influence skeletal muscle function and exercise performance. To date, there have been no similar observations reported in humans. A common experimental approach in animal studies to temporarily disrupt the gut microbiome is through the use of antibiot...

Countermeasures to Circadian Misalignment
NCT04966351
Recruiting
Insufficient sleep and circadian misalignment are independent risk factors for the development of obesity and diabetes, yet few strategies exist to counter metabolic impairments when these behaviors are unavoidable. This project will examine whether avoiding food intake during the biological night can mitigate the impact of circadian misalignment on metabolic homeostasis in adults during simulated night shift work. Findings from this study could identify a translatable strategy to minimize meta... Read More
