One of the Causes of Amenorrhea is hypothalamic amenorrhea, which is a deficiency in the amplitude and/or frequency of endogenous Gonadotropin-releasing hormone (GnRH) Pulses. The results of this leads to anovulation and cessation of the menstrual cycle. Pulsatile GnRH has been widely used in the United States (US), Canada, and Europe for almost 40 years in the treatment of primary hypothalamic amenorrhea. It has a favorable safety profile and a high degree of effectiveness in enabling ovulation and spontaneous pregnancy. At the moment there are no other GnRH products on the market, nor are there any other drugs marketed for induction of ovulation in women with primary hypothalamic amenorrhea in the US, creating a clear unmet medical need. The goal of this trial is to characterize the exposure variability of GnRH when administered via the OmniPod.

• Statement of the Problem and Justification Cognitive performance under physiologically stressful conditions is critical in high-demand environments such as military operations, diving, and firefighting. One such stressor is restricted breathing, which can occur due to equipment (e.g., masks, regulators) or environmental pressures (e.g., underwater). Restricted breathing has been shown to increase physiological strain, which may in turn impact attention, reaction time, and task execution. Despite this, there is limited research examining how different breathing strategies can mitigate the cognitive effects of restricted respiration. Understanding whether specific breathing techniques can preserve cognitive function under stress has practical implications for operational readiness, safety, and task performance in extreme or demanding environments. • Synopsis of Relevant Research Previous human studies have shown that controlled breathing techniques, such as tactical or box breathing (inhale-hold-exhale-hold patterns), can reduce anxiety and improve focus in stressful situations. For example, tactical breathing has been adopted in military and law enforcement settings to enhance performance under pressure. Other research in sports psychology and respiratory therapy suggests that altering breathing frequency or depth can modulate autonomic nervous system activity, potentially affecting cognitive control and reaction time. Additionally, psychomotor vigilance tasks (PVTs) have been widely used to assess the impact of physiological stressors - such as sleep deprivation, hypoxia, and fatigue - on sustained attention and reaction time. However, few studies have directly examined the interaction between structured breathing patterns and PVT performance during restrictive breathing loads. • Importance and Next Step This study represents a logical next step in understanding how breathing techniques can buffer against cognitive decline under conditions that simulate real-world respiratory restriction (e.g., underwater diving). By directly comparing the effects of two distinct breathing strategies during a controlled, restrictive breathing task, this research will help determine whether certain techniques are more effective in preserving attention and reaction time. The findings could inform training and operational protocols for individuals working in challenging environments, as well as guide future studies into breathing-cognition interactions under physical stress.
The purpose of this research is to determine whether a procedure called capillaroscopy can help distinguish patients who are diagnosed with GAVE (gastric antral vascular ectasia) with an autoimmune disease versus idiopathic/other conditions based on EGD findings.
The goal of this observational study is to learn about the levels of nicotinamide adenine dinucleotide (NAD) in the brains of people with Alzheimer's disease.

Eight months later, they will have a second, similar, brain imaging session.
The goal of this clinical trial is to learn how GLP-1 and GIP agonists effect bowel preparation in patients scheduled for colonoscopies. The main questions it aims to answer are: * Does GLP-1 and GIP agonist increase the rate of inadequate bowel preparation? * Does the quality of bowel preparation differ in patients who hold vs. those who continue a single dose of their GLP-1 or GIP agonist medication? * Are there any differences in the rates of complications gastric aspiration in patients who hold vs. continue a single dose of their GLP-1 or GIP agonist medication?
The goal of this clinical trial is to evaluate the effectiveness of Immediate Lymphatic Reconstruction (ILR) in preventing breast cancer-related lymphedema (BCRL) in high-risk patients. It will also assess the safety and quality of life outcomes associated with the procedure. The main questions it aims to answer are: Does ILR reduce the incidence of BCRL in patients undergoing axillary lymph node dissection (ALND)? What are the patient-reported outcomes and quality of life differences between those who receive ILR and those who do not? Participants will be identified as high-risk for developing BCRL through a multidisciplinary tumor board and referred to a specialized clinic for further evaluation. High-risk patients will undergo a series of screening tests, including bioimpedance spectroscopy (BIS), circumferential limb measurements, and infrared 3D perometry. Participants will be randomly assigned to one of two groups: Intervention Group (Study Arm A): Undergo ILR during ALND surgery, where preserved lymphatic channels are connected to nearby veins to prevent lymphedema. Control Group (Study Arm B): Will not receive ILR, but efforts will be made to preserve lymphatic channels during surgery. Patients will be blinded to their group assignment. Post-surgery, all participants will receive education from a certified lymphatic physical therapist. At the 2-week postoperative visit, participants will be further randomized into two postoperative monitoring protocols: BCRL Clinical Pathway: Patients will have regular follow-up visits every three months for two years, including repeat BIS, limb measurements, perometry, and quality of life questionnaires (LYMQOL and ULL-27). Standard of Care: Patients will be monitored only if they experience BCRL symptoms or after two years from ALND. The study will compare the outcomes of both groups, with a focus on the incidence of BCRL and patient quality of life, and will benchmark these results against published literature on breast cancer patients.
