Assessment of Worldwide Acute Kidney Injury Epidemiology in Neonates 2.0
Description

There is a growing focus on short- and long-term kidney health in neonates, including those with acute kidney injury (AKI). AKI occurs commonly in the Neonatal Intensive Care Unit (NICU) and is associated with adverse outcomes. In addition to poor outcomes during the hospitalization, infants discharged from the NICU may have an increased burden of kidney disease during childhood. Studies of long-term kidney function in children born prematurely show a fourfold increase in chronic kidney disease (CKD) by adolescence and into adulthood. Despite the landmark findings of the Assessment of Worldwide Acute Kidney Injury Epidemiology in Neonates (AWAKEN) study, the limitations of this study are notable. First, the AWAKEN study enrolled infants admitted in 2014, making the data now over 10 years old. Much has changed in neonatal practice (e.g. increased AKI awareness, treatment strategies). Secondly, the findings of the AWAKEN study were geographically limited. While the AWAKEN study was multi-national and multi-center, it represented only 24 centers (22 from North America, 1 from India and 1 from Australia). Finally, information collected from AWAKEN ended at hospital discharge. The investigators seek to leverage the strength of the Neonatal Kidney Collaborative along with other organizations and collaboratives interested in neonatal kidney health to address these gaps. Therefore, the investigators are conducting a second, modified iteration of this study entitled "AWAKEN 2.0". AWAKEN 2.0 will be a multi-center multi-national retrospective analysis utilizing similar methodology to the AWAKEN study.

Addressing Cardiometabolic Health Inequities by Early Prevention in the Great Lakes Region Project 1 - Epidemiology (ACHIEVE P1-EPI)
Description

This project is part of the ACHIEVE GREATER (Addressing Cardiometabolic Health Inequities by Early PreVEntion in the GREAT LakEs Region) Center (IRB# 100221MP2A), the purpose of which is to reduce cardiometabolic health disparities and downstream Black-White lifespan inequality in two cities: Detroit, Michigan, and Cleveland, Ohio. The ACHIEVE GREATER Center involves separate but related projects that aim to mitigate and understand health disparities in risk factor control of chronic conditions, (hypertension, heart failure, and coronary heart disease) which drive downstream lifespan inequality. The present study is the prospective observational cohort component of ACHIEVE P1- EPI (Project 1) of the ACHIEVE GREATER Center and serves to characterize the population of patients with blood pressure (BP) levels above normal attending The Wayne Health Mobile Health Unit (MHU) events to better understand key factors (e.g., social determinants of health) that convey information about baseline BP levels and related clinical outcomes (e.g., follow-up clinic visits, BP control).

Linkage of Medicaid Enrollment Information to Surveillance, Epidemiology and End Results Data
Description

Background: The SEER database collects data about people with cancer. SEER stands for Surveillance, Epidemiology, and End Results. Medicaid is a kind of health insurance. It is for people who have low income or serious medical needs. Many studies have shown that Medicaid recipients with cancer are more likely to be diagnosed later in the disease than people with other insurance. They are also less likely to get treatment. Researchers want to compare Medicaid data and SEER data. They want to make this available to other scientists. Objectives: To link people in the SEER database to Medicaid data for the years around their cancer diagnosis. To create a file that contains SEER case numbers linked to Medicaid numbers. Eligibility: No people are enrolled in this study. Design: The SEER finder file will be securely uploaded to the CMS Data Center. The finder file will be matched against the Medicaid Personal Summary file at the CMS Data Center. If participants appear in both the SEER file and Medicaid file, their data will be extracted. The dates of Medicaid data will be compared with the SEER date of diagnosis. Researchers will see if the Medicaid dates fall in certain periods. These are 12 months before, the month of, and 11 months after diagnosis. If participants are eligible for Medicaid for these periods, a flag will be created in the file. It will note the participants is eligible and why. The SEER finder file will be destroyed. The only data saved will be: Each participant's unique random SEER case number linked to their Medicaid number Monthly flags about Medicaid eligibility

Assessment of Worldwide Acute Kidney Injury Epidemiology in Neonates
Description

Introduction: Based on single-center data, approximately 1 of every 3 newborns admitted to tertiary level neonatal intensive care units (NICU) develops acute kidney injury (AKI), and those with AKI have significantly worse outcomes. To stimulate discussion among researchers, the NIH NIDDK sponsored a workshop on neonatal AKI in April 2013. At that workshop, the group recognized the need to improve collaborations between neonatologists and nephrologists within and across centers. The investigators have created a multi-institutional, multi-disciplinary group, Neonatal Kidney Collaborative (NKC), in order to address the following critical needs identified at the workshop: AWAKEN is the inaugural study of this new collaboration. 1. Development of a standardized evidence-based definition of neonatal AKI 2. Evaluation of risk factors that predispose neonatal to AKI 3. Investigation into how fluid provision/ balance impacts biochemical and clinical outcomes

Molecular Epidemiology of Acute Myelogenous Leukemia
Description

Little is known about the epidemiologic risk factors associated with the development of acute myelogenous leukemia (AML), and less is known about the role that genetic susceptibility plays in the development of AML. We propose to conduct a population-based study to investigate genetic susceptibility in adult AML patients, both de novo and treatment-related in a well-defined geographical area. Using a case-control design, we will prospectively enroll 400 patients from Texas and 800 healthy controls. Controls will be recruited using random digit dialing, and will be matched to the cases by age, gender, and ethnicity. Epidemiological and demographic information will be obtained through personal interviews, and will be integrated with clinical information, cytogenetic data, and genotypic markers. Blood specimens will be collected on all participants, who will be genotyped for markers associated with activation and detoxification of chemical carcinogens, including chemotherapy drugs. Polymorphisms in genes such as cytochrome p450 (CYP2E1), glutathione S-transferases (GSTT1, GSTM1, GSTP1), epoxide hydrolase (HYL1), NADPH-quinone oxidoreductase (NQO1), and myeloperoxidase (MPO) will be analyzed. This study will provide insight into the role that these susceptibility markers, along with clinical epidemiological, and cytogenetic factors, play in the identification of people at risk of developing AML. Understanding how genetic predisposition and exogenous exposures interact to determine AML susceptibility will allow the development of prevention strategies in the future.

Genetic Epidemiology of Ovarian Aging
Description

The purpose of this study is to identify clinical and genetic markers of ovarian aging. In this process, we will evaluate environmental factors that may affect fertility and the age at which fertility declines, and may influence the age at which women enter menopause. Wide variability exists between women both in the age at which menopause occurs and the rate of decline in oocyte number and reproductive capability. As the loss of ovarian function has profound impact on women's hormonal milieu and their subsequent risk for the development of disease, improving our understanding of the factors that determine the timing and rate of reproductive aging is critical to improving quality of life for all women. In addition, improving our understanding of reproductive aging has profound economic, and social, implications given the complex choices women face regarding the timing of childbearing and the growing burden of infertility. While the inter-individual variability in age at menopause has a large genetic component and possible environmental influences, to date no studies have addressed the relationship between oocyte number as reflected by antral follicle count (AFC) and genetic inheritance. We hypothesize that ovarian aging, as reflected by antral follicle count, is largely determined by common genetic polymorphisms that impact the initial oocyte endowment and/or the rate of oocyte loss over time thus lowering antral follicle count for any given age. We further hypothesize that antral follicle count will be an improved marker of ovarian aging. Thus, we propose a study of the genetic and environmental factors that influence age-specific variability in antral follicle count.

Improving Outcomes and Reducing Disparities for Patients With Inflammatory Bowel Disease Through Epidemiology and Enhanced Disease Management
Description

The goal of this clinical trial is to learn whether IBD patients have better disease outcomes and feel more empowered to manage their condition if they have access to text messaging with their clinical team and if their symptoms are more regularly monitored through text-based surveys. Researchers will compare participants who have access to text-based monitoring, communication and education to participants who have access to text-based education alone. Researchers will also examine if different social and other non-medical factors impact IBD symptoms and quality of life. All participants will: * complete 5 brief on-line surveys over 12 months about their IBD and social risk factors, * receive IBD education content by text message up to 2 times a week. Some participants will also: * receive additional surveys by text to monitor their IBD progression, * have the opportunity to directly text message their IBD medical team.

Influenza & COVID-19 Obstetric and Perinatal Epidemiology Study in India
Description

This study will be conducted as a prospective cohort study, enrolling all eligible women in their first trimester of pregnancy during a baseline visit during week 6-13 of pregnancy at Government Medical College Hospital, Nagpur. The Hospital provides primary, secondary, and tertiary care and the obstetric department delivers about 10,000 babies a year. The hypothesis is that co-infection of other respiratory viruses (ORV), particularly COVID-19 and Influenza increases the risk of adverse pregnancy outcomes in mothers and babies and could address the current standard of care in India to not vaccinate pregnant women during pregnancy, by either encouraging vaccination against both viruses before planning a pregnancy or during pregnancy based on global data supporting the safety of this strategy.

Natural History, Epidemiology and Pathogenesis of Severe HPV-Related Diseases (Neptune)
Description

Background: Most symptoms of human papillomaviruses (HPV) infection, do not cause serious health problems, but some do. As HPV can cause uncontrolled growth of infected cells, some people can develop benign skin lesions, larger warts, genital lesions, tumors or cysts that do not respond to treatment. Researchers want to learn why. Objective: To better understand why some people are more likely than others to get sick from HPV infection, and why medicine or surgery is not always effective. Eligibility: People aged 3 years and older who have had multiple outbreaks of HPV-related warts and/or lesions that do not respond to treatment. Healthy relatives are also needed. Design: Participants will be screened with a medical history, physical exam, and blood tests. Participants may have study visits as an outpatient or an inpatient (admitted overnight to the NIH hospital) and be followed over several years by our doctors and researchers at the NIH. Participants may have a cervical and/or anal Pap test. They may give samples of semen, cervicovaginal secretions, urine, saliva, or stool. Small pieces of skin, the inside of the cheek, and/or the gums may be collected with a punch or scrape biopsy to understand how HPV affect the growth of cells. Mucus and skin may be collected by rubbing the area with a cotton swab. Collection areas may include the inside the mouth, nostrils, skin, genitals, and/or in or around the anus. Biopsies may be collected. If participants need to have a biopsy as part of medical care, then we may ask if extra samples can be collected for research. Biopsies we may collect are bone marrow, lymph node, genitals, or in or around the anus. Participants may have leukapheresis. Blood is taken from a needle placed in one arm. A machine separates out the white blood cells. The rest of the blood is returned through a needle in their other arm. Samples may be used for genetic tests and/or to make special cells called induced pluripotent stem cells. Participants may have follow-up visits once a year for 10 years. Benefits: We are not testing new HPV treatments in this study and you might not benefit from participating. However, we may learn new information about your condition that we will share with you and your doctor. We may make recommendations for your medical care based on current accepted treatment. What we learn from you and other participants in this study might help other people. We hope we can use this information to develop new treatments and therapies in the future....

Genetic Epidemiology of Rotator Cuff Tears: the CuffGEN Study
Description

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.

Environmental Epidemiology of Essential Tremor
Description

This study's research is devoted to studying the causes of tremor, and especially essential tremor (ET), which is the most common type of tremor. Previous studies have revealed a link between harmane \[HA\], a dietary neurotoxin, and ET; these studies now also suggest a link between this toxin and Parkinson's disease (PD), a related tremor disorder. Yet these links are tentative rather than conclusively established; therefore, in this new patient-based proposal, which incorporates investigations spanning two continents (North America and Europe), utilizes several complementary study designs (prospective cohort, case control), and draws on several types of tissue (blood, brain), the investigator's goal is to nail down the links between HA and ET and to further solidify the emerging links between HA and PD.

Characterizing the Perioperative Epidemiology of SARS-CoV-2 (COVID-19) Spread for Quality Improvement of Perioperative Infection Control Program
Description

In a case-series analysis, up to 20 patients undergoing elective or urgent/emergent surgery that are COVID-19 positive will be approached for patient consent. OR PathTrac (RDB Bioinformatics, Omaha, NE 68154) collection kits will be utilized for sampling of 48 sampled time/locations per patient. Patient sampling locations will include the nasopharynx and oropharynx. Operating room environmental locations will include areas in the patient care arena such as the anesthesia machine. Samples of each location will be obtained before and after treatment with UV-C (Helios, Surfacide), germicidal, ultraviolet light and other infection control practices that are currently in place, such as utilization of preoperative chlorhexidine wipes, nasal iodine, improved hand hygiene, and improved vascular care. UV-C light for environmental cleaning is not regulated by the FDA. Samples will be processed by RT-PCR for presence of SARS-CoV-2 nucleic acid. Positive samples will be sent to Dr. Stanley Perlman's lab to assess viability. Samples will also be assessed for S. aureus as a process control. We will characterize the epidemiology of perioperative SARS-CoV-2 spread as a quality improvement initiative to improve our current perioperative infection control bundle and to serve as the platform for national dissemination of a perioperative COVID-19 defense strategy.

Epidemiology of Silent and Overt Strokes in Sickle Cell Disease
Description

Sickle Cell Disease (SCD) is a rare disease occurring in an estimated 100,000 individuals, often poor and underserved, in the US. Silent and overt strokes contribute significantly to morbidity in adults with SCD, resulting in functional impairment, challenges with school and job performance, and premature death. Five NIH-funded randomized controlled trials have identified therapies to prevent silent and overt strokes in children with SCD, including monthly blood transfusion therapy (for preventing initial and recurrent strokes) and hydroxyurea (for preventing initial strokes). Despite the observation that at least 99% of children with SCD in high-income countries reach adulthood, and approximately 60% of adults will experience one or more strokes (\~50% with silent strokes and \~10% with overt strokes), no stroke trials have established therapeutic approaches for adults with SCD. For adults with SCD, inadequate evidence-based guidelines exist for secondary stroke prevention strategies. Applying stroke prevention strategies in children may not be effective for stroke prevention in adults with SCD, particularly given the high rate of co-morbidities. Identifying subgroups of adults with SCD and higher incidence coupled with the contribution of established stroke risk factors in the general population (smoking, diabetes, obesity, renal disease) will provide the requisite data required for the first-ever phase III clinical trials focused on secondary stroke prevention in adults.
