Rotator cuff tear is one of the most common reasons to seek musculoskeletal care, and cuff repair is one of the fastest growing ambulatory surgery procedures. However, the etiology of cuff tears, reasons for variability treatment success, and causes of FI are poorly understood. A large-scale genome-wide association studies (GWAS) using imaging-verified rotator cuff tear cases and controls can address limitations in rigor of prior research and assess the genetic basis of FI and functional outcomes of cuff tear treatments. Primary Objective: To conduct a case-control GWAS of imaging-verified symptomatic rotator cuff tear in approximately 3000-6000 individuals and replicate findings in an independent set of 3000-6000 or more imaging-verified individuals to identify common variants in several genetic loci that increase risk for rotator cuff tears. Hypothesis: Common variants in several genetic loci increase risk for rotator cuff tears. Secondary Objectives: 1. To perform an imputed transcriptome-wide association study (TWAS) to identify and prioritize gene targets associated with rotator cuff tear by integrating GWAS summary statistics and gene-expression weights from muscle and adipose tissue available in the GTEx project. Hypothesis: Genetically predicted gene expression of multiple genes in muscle and adipose tissue are associated with rotator cuff tear. 2. To identify if single nucleotide polymorphisms (SNPs) associated with rotator cuff tear and their genetic risk score (GRS) predict improved pain and function as measured by American Shoulder and Elbow Surgeons Standardized Form (ASES) and other outcome measures. Hypothesis: Select SNPs and GRS predict ASES outcome. 3. To identify genetic variants associated with Fatty Infiltration (FI) in patients with cuff tears in a two stage GWAS of imaged rotator cuffs and to prioritize gene targets through an imputed-TWAS in muscle and adipose tissue. Hypothesis: Multiple genetic variants are associated with FI and some exert their influence by altering gene expression in the muscle and adipose tissue.

This phase II/III trial studies the best approach in improving quality of life and survival after a donor stem cell transplant in older, weak, or frail patients with blood diseases. Patients who have undergone a transplant often experience increases in disease and death. One approach, supportive and palliative care (SPC), focuses on relieving symptoms of stress from serious illness and care through physical, cultural, psychological, social, spiritual, and ethical aspects. While a second approach, clinical management of comorbidities (CMC) focuses on managing multiple diseases, other than cancer, such as heart or lung diseases through physical exercise, strength training, stress reduction, medication management, dietary recommendations, and education. Giving SPC, CMC, or a combination of both may work better in improving quality of life and survival after a donor stem cell transplant compared to standard of care in patients with blood diseases.

Parasympathetic nervous system (PNS) is part of the body's autonomic nervous system(PNS) protects body against inflammation. Study shows that reduced PNS function activity is associated with persistent inflammation. Preliminary data from the studies shows, that post-COVID-19 POTS patients have reduced parasympathetic (PNS) function. Given that the PNS protects against inflammation, this clinical trial aims to prove that post-COVID-19 POTS is caused by reduced PNS activity, which in turn, contributes to persistent inflammation, orthostatic intolerance, and OI symptoms. The study will evaluate immune cell activation in post-COVID-19 POTS and patients with history of COVID-19 infection without sequelae and correlate this with the degree of decreased PNS activity.

Leiomyosarcoma (LMS) is one of the most prevalent soft tissue sarcomas (STS) and can occur in various sites including soft tissue, uterus and retroperitoneal large vessels. Metastatic disease occurs in approximately 50% of patients diagnosed with leiomyosarcoma and prognosis is poor in setting of metastatic disease. A minority of patients benefit from treatment with chemotherapy and early biomarkers of benefit from treatment are lacking. A biomarker of tumor response and patient survival benefit from chemotherapy early in the course of chemotherapy would be of significant impact in treatment planning. Circulating tumor DNA (ctDNA) is present in blood of patients with advanced/metastatic cancer and may serve as biomarker of tumor response to chemotherapy. Blood samples will be collected prior to and during and chemotherapy, and analyzed for ctDNA and for mutations in genes that are associated with increased risk of developing sarcoma. Tumor tissue will be collected and analyzed for changes in genes. Digital images of the sarcoma from CT or MRI scans obtained during treatment will be obtained for advanced radiomic analysis. Study participants will be asked to complete a questionnaire on attitudes and understanding of genetics and genetic testing.

Effect of Donepezil on Speech Recognition in Cochlear Implant Users

Hearing loss is a major cause of disability that affects over 48 million Americans. There are currently no medications used to treat sensorineural hearing loss. Cochlear implants can significantly restore hearing in adults with moderate to profound sensorineural hearing loss, but their utility is limited by the wide variability in hearing outcomes. Differences in cochlear implant outcomes may be explained by neuroplasticity, as neural networks must reorganize to process the new auditory information provided by the implant. The investigators predict that cholinergic enhancement with donepezil (an acetylcholinesterase inhibitor) may facilitate cortical reorganization in cochlear implant users, leading to functional improvements in speech recognition and cognition. In addition to taking donepezil, study participants will be asked to increase their daily processor use. Studies suggest that increasing daily device use can improve speech recognition, and this study will explore whether this effect can be augmented further with donepezil. In this randomized, double-blind controlled trial, the investigators aim to assess the effects of donepezil on speech recognition, cortical plasticity, and cognition. Participants will start daily treatment with either donepezil 5 mg or placebo. Participants will be followed longitudinally at 1 month and 3 months after starting the study. The findings from this study will provide important insight into the mechanisms of hearing restoration and could potentially improve hearing and cognitive outcomes for future cochlear implant users.

This phase III trial compares early treatment with venetoclax and obinutuzumab versus delayed treatment with venetoclax and obinutuzumab in patients with newly diagnosed high-risk chronic lymphocytic leukemia or small lymphocytic lymphoma. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Immunotherapy with monoclonal antibodies, such as obinutuzumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Starting treatment with the venetoclax and obinutuzumab early (before patients have symptoms) may have better outcomes for patients with chronic lymphocytic leukemia or small lymphocytic lymphoma compared to starting treatment with the venetoclax and obinutuzumab after patients show symptoms.

Hydrocephalus is a potentially debilitating neurological condition that primarily affects babies under a year of age and has traditionally been treated by inserting a shunt between the brain and the abdomen. A newer endoscopic procedure offers hope of shunt- free treatment that may reduce complications over a child's life, but it is not clear if the endoscopic procedure results in similar intellectual outcome as shunt. Therefore, the investigators propose a randomized trial to compare intellectual outcome and brain structural integrity between these two treatments, to help families make the best treatment decision for their baby.
