People with hereditary hemorrhagic telangiectasia (HHT) often experience frequent and severe nosebleeds that can disrupt daily life and lead to anemia, medical procedures, and reduced quality of life. This study is testing a new nasal ointment called TOR-582, which contains sirolimus, to determine whether it can be used safely when applied inside the nose. Adults with HHT and frequent nosebleeds will be invited to participate. Participants will first complete one week of observation without treatment, followed by up to 12 weeks of applying the study ointment inside each nostril twice daily. Different participants will receive different strengths of the ointment so researchers can identify the safest dose. During the study, participants will attend study visits, complete questionnaires about their nosebleeds and quality of life, keep a daily nosebleed diary, undergo nasal examinations, and have blood tests to monitor safety and medication levels. The information gained from this study will help determine whether this topical treatment can be safely studied further and will support the development of a new, less invasive option for managing nosebleeds in people with HHT.

Female life stages including premenopausal, perimenopausal, postmenopausal, are characterized by changing concentrations and patterns of hormones. The premenopause stage represents the reproductive years with normal menstrual cycles lasting between 21-35 days. The perimenopause stage is the beginning of the menopause transition and can last up to 10 years. During this transition, menstrual cycles become longer and irregular in length (7 days or longer). After 12 consecutive months with no period, the transition is complete into the postmenopause stage. Hormones that change across the lifespan are known to influence systems that regulate thirst, fluid balance, and sodium balance. Yet, fluid balance across life stages remains poorly understood, with no direct comparisons across all three life stages. The purpose of this study is to evaluate the effect of female life stage on rehydration with water and electrolyte solution after overnight fast and fluid restriction

The primary objective is to establish a Cleveland Clinic-led registry designed to integrate continuous physiological data from consumer wearables, captured by the HeartBit app and a Case Western Reserve University (CWRU)-based platform, with clinical data from patients' individual Electronic Health Record (EHR). This proposal is for understanding the use of personal wearable devices (such as: Fitbit, and Apple Watch) to gather physiological data (such as: heart-rate, steps taken, sleep cycles, and calories expended) and correlate those data with self-reported health status. The research team intends to collect all of the data generated by the participant's personal wearable devices and to perform an integrated analysis of the physiological data generated by the wearable devices. The investigators specifically aim to uncover patterns from the data that they can evolve models from. The investigators' goal is to better predict and diagnose the adverse effects associated with daily lifestyle, including cardiovascular risk, musculoskeletal, metabolic risks, stress, and sleep disturbances. These data may be used to better understand the daily habits and lifestyle choices to possibly predict a person's health and disease risk to provide a more comprehensive diagnosis with early recognition and prevention. As wearable devices become more accurate and cheaper to purchase for the general public, integrative analysis of wearable data from multiple devices may lead to models that can be used by clinicians and basic scientists to make inferences about the daily lifestyle and its effects on health and disease.

The goal of this study is to determine the impact of MVM supplementation on clinical and biochemical markers associated with healthy aging, with a particular focus on mitochondrial function and metabolism. Specifically, changes in mitochondrial respiration using isolated blood cells will be measured. This method has been used to compare with various other age-related markers of health such as physical function, gait speed, and resting metabolic rate. It is hypothesize that MVM supplementation will impact the function of blood cells. MVM supplementation impacts other markers of health, including serum nutrient levels, metabolomic profiles, physical function, and skeletal muscle composition and quality will be explored. These comprehensive assessments will provide insights into the potential benefits of MVM supplementation for healthy aging and address critical gaps in our understanding of its immediate effects. Further, this study will aid in the understanding of how multivitamin supplements can support heathy aging in mid-life adults, a key time to start including wellness programs in people's lives.

Precision oncology has led to a growing population of adults with advanced cancer living increasingly longer lives in the face of profound uncertainty about the future, with over half reporting moderate to high fear of cancer progression (FoP). These fears are associated with anxiety and depression, over-use of healthcare, physical symptom burden, higher treatment regret, fatigue, and, in many studies, poorer quality of life. Moreover, FoP is strongly correlated with cancer-related trauma symptoms-physical hyperarousal, intrusiveness of cancer thoughts/images, and avoidance of cancer-related thoughts and feelings, suggesting overlapping symptoms. While behavioral interventions exist to target fear of recurrence in early-stage cancer survivors, there is a dearth of behavioral interventions to address FoP or cancer-related trauma symptoms in adults with advanced cancer, and no known published randomized trials of such interventions in the United States. In addition, cutting-edge developments for the treatment of trauma in general populations have not been adapted to cancer populations. To address these critical gaps, we adapted a cutting-edge behavioral treatment for trauma to reduce FoP and cancer-related trauma symptoms among adults with advanced cancer. The intervention, titled EASE, is based on written exposure therapy, an efficacious approach for reducing trauma symptoms in general populations that is better accepted and far briefer than other gold-standard approaches. EASE adapts this approach to help advanced cancer patients with elevated FoP and cancer-related trauma symptoms reduce their fear of the future by using written exposure focused on their future worst-case scenario with cancer. Informed by the NIH stage model, we evaluated EASE delivered by telehealth in an open pilot trial for 29 adults with late-stage cancer and elevated FoP and cancer-related trauma symptoms. Pilot findings show strong acceptability, feasibility, and efficacy potential. We now propose to conduct the first randomized trial of EASE, and, thus, first known randomized trial in the United States of a behavioral intervention for FoP and cancer-related trauma symptoms among adults with advanced cancer. This 2-arm trial (N=250) will compare EASE delivered by telehealth with Usual Care (UC). We aim to compare EASE to UC on FoP and cancer-related trauma symptoms (primary outcomes) and anxiety, depression, hopelessness, and quality of life, at post-intervention (Aim 1) and follow-up (Aim 2). We will evaluate mechanisms for EASE relative to UC (Aim 3). Offering EASE in both English and Spanish, and by telehealth, increases access. Simple content increases scalability. Rigorous evaluation of EASE has the potential to provide a paradigm-shifting intervention ready for dissemination and to inform evidence-based care guidelines for distressed adults with advanced cancer.
