The goal of this clinical trial is to learn the formation and recovery rate of methemoglobin (MetHb) in severely sick patients with pneumonia who receive high doses of inhaled nitric oxide (iNO) therapy at 250 parts per million (ppm), not exceeding 300 ppm. Meanwhile, the benefits of the therapy to treat severely sick patients with pneumonia will be explored. Patients who are 18 years or older, newly diagnosed with pneumonia, and severely sick with requirement of a breathing machine could be included. The main questions it aims to answer are: How does methemoglobin change through the iNO treatment? Does iNO therapy increase the number of patients recovering from pneumonia? Researchers will compare iNO treatment to placebo, which means using the same device as the treatment group without delivering the study drug. Participants will: - Receive iNO treatment starting at 250 ppm, not exceeding 300 ppm, 40 min, every 6 hours, from day 1 to day 5 - Be followed up for 60 days

This clinical trial compares telephone-based physical activity coaching to self monitored physical activity for improving physical function in older adults who are undergoing surgery for lung cancer and their caregivers. Lung cancer surgery in older adults is associated with functional declines and unique challenges. Performing physical activity around the time of surgery has been shown to improve functional outcomes in patients and exercise programs delivered via telehealth may improve access and convenience for patients and minimize participant burden. Telephone-based physical activity coaching may improve physical functioning for older adults with lung cancer who are undergoing surgery.

The goal of this study is to objectively test one's sense of smell, called olfaction, in participants with Subjective Cognitive Concerns (SCC), Mild Cognitive Impairment, Mild Behavioral Impairment (MBI), and age-matched controls. The main question it aims to answer is whether the AROMHA Brain Health Test could serve as a predictive biomarker of neurodegenerative disorders. This understanding will aid in the development of a noninvasive, cost-effective diagnostic tool that reliably and specifically distinguishes disease and normal aging populations. Participants will take the approximately 45-minute AROMHA Brain Health Smell Test where they will peel and sniff labels on the physical smell cards and answer questions on the web-based app relating to what they smelled. Participants will undergo tests for odor intensity, odor identification, odor discrimination, and episodic olfactory memory, but will not be provided the results of these tests.

Without an explanation for severe and sometimes life-threatening symptoms, patients and their families are left in a state of unknown. Many individuals find themselves being passed from physician to physician, undergoing countless and often repetitive tests in the hopes of finding answers and insight about what the future may hold. This long and arduous journey to find a diagnosis does not end for many patients- the Office of Rare Diseases Research (ORDR) notes that 6% of individuals seeking their assistance have an undiagnosed disorder. In 2008, the National Institutes of Health (NIH) Undiagnosed Diseases Program (UDP) was established with the goal of providing care and answers for these individuals with mysterious conditions who have long eluded diagnosis. The NIH UDP is a joint venture of the NIH ORDR, the National Human Genome Research Institute Intramural Research Program (NHGRI-IRP), and the NIH Clinical Research Center (CRC) (1-3). The goals of the NIH UDP are to: (1) provide answers for patients with undiagnosed diseases; (2) generate new knowledge about disease mechanisms; (3) assess the application of new approaches to phenotyping and the use of genomic technologies; and (4) identify potential therapeutic targets, if possible. To date, the UDP has evaluated 3300 medical records and admitted 750 individuals with rare and undiagnosed conditions to the NIH Clinical Center. The NIH UDP has identified more than 70 rare disease diagnoses and several new conditions. The success of the NIH UDP prompted the NIH Common Fund to support the establishment of a network of medical research centers, the Undiagnosed Diseases Network (UDN), for fiscal years 2013-2020. The clinical sites will perform extensive phenotyping, genetic analyses, and functional studies of potential disease-causing variants. The testing performed on patients involves medically indicated studies intended to help reach a diagnosis, as well as research investigations that include a skin biopsy, blood draws, and DNA analysis. In addition, the UDN will further the goals of the UDP by permitting the sharing of personally identifiable phenotypic and genotypic information within the network. By sharing participant information and encouraging collaboration, the UDN hopes to improve the understanding of rare conditions and advance the diagnostic process and care for individuals with undiagnosed diseases....

This is a mixed-methods study designed to develop and evaluate an innovative coaching program for physician trainee mothers. Approximately 48 participants will be recruited from informational flyers posted in resident work areas and distributed by program directors and GME. Interested participants will email study staff. Participants will be randomized to the control or intervention arm. Intervention participants will meet monthly with a novice physician coach of their choice (one-on-one) and a certified physician coach (with an assigned group of 6 peers through video-conferencing). Participants in both arms of the study will respond to surveys at three points: enrollment (baseline), 4 months, and 7 months. At each point, they will spend approximately 10 minutes filling the survey. The survey will query demographics, burnout, professional fulfillment, imposter phenomenon, self-valuation, self-efficacy, resilience, quality of life, and impact of work on professional relationships. The coaching intervention will last 4 months, and the 7 month survey will be used only to assess long-term effects of the intervention. At the conclusion of the study (7 months after enrollment), participants will be interviewed over video communication (secure Partners or Harvard Zoom) for approximately 30 minutes.

Transthyretin amyloidosis (ATTR) is a disease where the normally occurring transthyretin (TTR) protein falls apart and forms amyloid, a sticky plaque- like substance that accumulates in different organs in the body and can cause damage to the organ. There are two ways that the TTR protein can fall apart. One way occurs as a person ages, where the normal TTR protein can fall apart and form amyloid that may no longer be sufficiently cleared by the body. This type of ATTR is known as wild-type ATTR (ATTRwt). The other way occurs when a person inherits a defective TTR gene that causes the TTR protein to spontaneously fall apart. This form of the disease is known as variant ATTR (ATTRv) and can be detected in adults by a genetic test of their TTR gene before they age. Amyloid build-up in the heart causes the heart wall to become thick and stiff and can result in heart failure and even death. Accumulation of TTR amyloid in the heart is known as transthyretin amyloid cardiomyopathy or ATTR-CM. Amyloid can also deposit in the nerve tissues leading to nerve problems. Accumulation of TTR in the nerves is known as transthyretin amyloid polyneuropathy or ATTR-PN. Acoramidis is an experimental drug designed to bind tightly to TTR in the blood and stabilize its structure, so it does not form the harmful amyloid plaques that can cause damage to organs. This study is intended to determine if treatment with acoramidis in participants with ATTRv who have not yet developed any symptoms of disease can prevent or delay the development of ATTR-CM or ATTR-PN disease. If adults with an inherited defective TTR gene are treated early before any of the symptoms of disease have developed, it may be possible to delay the onset or prevent the disease entirely.
