Clostridioides difficile (C. difficile) is the most common healthcare-associated pathogen, causing >500,000 infections and >29,000 deaths per year in the US. Traditional approaches to reduce hospital-onset CDI focus on identifying, isolating, and treating symptomatic patients to prevent transmission to other patients. Recent genomic epidemiology studies, however, suggest that most hospital-onset CDI cases are attributable to asymptomatic carriers who either progress from colonization to active infection themselves or transmit C. difficile to other patients while asymptomatic. This trial will evaluate an intervention to pre-emptively identify asymptomatic C. difficile carriers and then implement a patient-tailored prevention package to protect the carrier from progression to active infection and to prevent transmission from the carrier to other patients.

Immunotherapies have improved cancer outcomes, but have a unique profile of immune-related adverse events (irAEs). Biorepositories have been established to collect data and samples to help improve our understanding of irAEs, however identifying patients who are eligible for these biorepositories in a timely fashion can be challenging. The goal of this study is to determine if an informatics system for automated irAE detection can improve registration to a prospective irAE biorepository (NCT04242095). The informatics system automatically "reads" participants' electronic health records (EHRs) and determines whether that patient may be experiencing an irAE. The main questions it aims to answer are: - Is it feasible to implement an informatics system for daily analysis of EHR data to detect irAEs? - Does the automated irAE detection system improve registration rates to an irAE biorepository at our institution following an eligible irAE? Researchers will compare standard irAE monitoring to informatics-assisted irAE monitoring to see if using the informatics system increases the registration rate and improves data entry efficiency and quality. Participants will: - Be randomly assigned to standard monitoring or informatics-assisted monitoring for irAE detection. - Have their EHR reviewed to collect demographic, medical, and cancer treatment history. - Be monitored for irAEs through daily automated analysis of their EHR data for up to 12 months or until registration in the biorepository.

This study is being done to find out if metformin is effective at reducing pain by delaying the onset of post-traumatic osteoarthritis (PTOA) after anterior cruciate ligament (ACL) reconstruction. This research study will compare metformin to placebo. The placebo tablet looks exactly like metformin, but contains no metformin. Placebos are used in research studies to see if the results are due to the study drug or due to other reasons. Metformin is approved by the U.S. Food and Drug Administration (FDA) to treat type II diabetes. Notably, it also has anti-inflammatory effects, suggesting it could benefit people who have an ACL injury and are undergoing ACL reconstruction.

Obstructive sleep apnea (OSA) is common and has major health implications but treatment options are limited. Some OSA patients with low arousal threshold wake up prematurely during an obstructive event and do not have time for spontaneous upper airway (UA) dilator muscle recruitment. As a consequence they are exposed to apnea and hypopnea cycling. In this protocol the investigators will test the effect of trazodone administered before sleep on OSA traits and OSA severity during sleep.

This research study aims to learn more about the impact the hormone aldosterone on the heart. Primary aldosteronism is a condition where the body's adrenal glands make too much of the hormone aldosterone, which can cause high blood pressure and increase the risk of heart and kidney disease. Treatment with medications that block aldosterone can reduce that risk. This study is trying to learn whether treatment with a medication that blocks aldosterone can improve heart function in people who make too much aldosterone.

The goal of the Molecular Characterization Trial (MCT) is to obtain biological specimens and data resources from patients enrolled on prospective trials, to ensure that the Harvard/UCSF ROBIN Center accomplishes its key objective of advancing our understanding of the biological mechanisms that underlie how radiation treats tumors but also can cause unwanted side effects. The MCT focuses on collection of research biospecimens before, during, and after radiation. Also critical to the MCT is the deep annotation of these research biospecimens with elements that complement each other to provide a holistic, detailed view of each patient. Annotated elements include those used in the past such as clinical and biological features but extend to factors we have so far neglected but must incorporate in the future such as dosimetry (precise anatomical measurement of radiation dose), artificial intelligence, computational biology, and natural language processing.

Hypothesis: The investigators hypothesize that genetic variants will alter gene expression in response to ischemia during cardiopulmonary bypass. To test this, the investigators will be taking small pieces of heart tissue from patients undergoing heart surgery before and after this period of ischemia. This will be compared to blood gene expression in blood cells and analyzed with the patients' genetic profile. This might allow us to assess the amount of inflammation that occurs when patients are on the heart-lung machine as well as examine the effects genes have on this critical time period.

Obstructive sleep apnea (OSA) is a highly prevalent disorder that has major consequences for cardiovascular health, neurocognitive function, risk of traffic accidents, daytime sleepiness, and quality of life. For years, a "classic" model of OSA has been used to describe the disorder, which fails to capture it's complexity. Recently, a model for OSA called drive-dependent OSA was discovered be more prevalent in the OSA population. This drive-dependent OSA is due to ventilation instability that occurs during respiratory events however these individuals have spontaneous increases in drive during respiratory events that stabilize their airway (i.e., via improving upper airway muscle activity) and reduce the risk of respiratory events in people with OSA. Therefore, by stabilizing the ventilatory drive, OSA should be treatable. Acetazolamide is a pharmacological ventilatory stimulant and has been previously shown to reduce OSA severity. As such in this study, the goal is to demonstrate acetazolamide improves OSA severity in 'drive-dependent' OSA people by improving drive-related pharyngeal obstructions compared to the 'classic' OSA people.

Obstructive sleep apnea (OSA) is common and has major health implications but treatment options are limited. OSA patients show a marked reduction in upper airway (UA) dilator muscle activity at sleep onset and this phenomenon leads to increased collapsibility of UA compared to normal subjects. In this protocol the investigators will test the effect of LTM1201AZ, LTM1201AT, LTM1201AD, LTM1201AG administered before sleep on OSA phenotype traits and OSA severity during sleep.

Surgery is currently the only potentially curative treatment modality for localized retroperitoneal sarcoma (RPS). Available studies regarding oncologic outcomes are mainly retrospective in nature, and RPS are recognized as a rare disease. Therefore, prospective analysis of high quality data is a top priority. Primary Objectives of this study are: - to prospectively collect standardized clinical data and radiological and pathological material from primary RPS patients treated with surgery at reference centers. - patient outcome will be evaluated in terms of overall survival (OS), disease-free survival (DFS), crude cumulative incidence (CCI) of local recurrence (LR) and distant metastasis (DM). Secondary Objectives: - to estimate the efficacy and safety of surgical treatment, including extended surgical approach to primary RPS; - to prospectively evaluate the impact of multimodality therapy, including radiation therapy and chemotherapy; - to identify clinical, radiological and pathological characteristics that may influence the oncological outcome or may be used as predictors of LR/DM/OS. These may be important biomarkers of disease; - to utilize collected pathological material for research collaborations.

In this study, researchers will learn more about the use of felzartamab in participants with immunoglobulin A nephropathy (IgAN). IgAN is a kidney disease caused by the buildup of an antibody called IgA in the kidneys over time. In people with IgAN, abnormal IgA and other antibodies form clusters that build up in the small filters of the kidneys, which leads to inflammation and damage. Felzartamab is designed to target certain immune cells that produce these abnormal antibodies. This study will focus on participants who have protein in their urine (proteinuria) as a result of damaged kidneys. The main goal of the study is to learn about the effect felzartamab has on proteinuria. The main question that researchers want to answer is: • How much does the amount of protein in the urine change from the start of the study to Week 36? Researchers will learn about the effect felzartamab has on the kidneys' ability to filter blood. They will also learn more about the safety of felzartamab and how it is processed by the body. The study will be done as follows: - Participants will be screened to check if they can join the study. - Participants will be randomized to receive either felzartamab or a placebo. A placebo looks like the study drug but contains no real medicine. - Neither the researchers nor the participants will know what the participants will receive. - Participants will receive felzartamab or placebo as intravenous (IV) infusions. The treatment period will last 24 weeks. - Afterwards, participants will enter a follow-up period which will last 80 weeks. - In total, participants will have 17 study visits. Participants will stay in the study for about 2 years.

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.
