Oral Bacteria and Immune System Problems Involved in Gum Disease (Periodontitis)
Background Gum disease is a condition in which the tissue around the tooth root becomes swollen and infected. This condition can cause tooth loss if it is not treated. Who gets gum disease and how bad it will be depends on (1) the different bacteria in the mouth and (2) …
Epstein-Barr Virus Antibody and Epstein-Barr Virus DNA for Nasopharyngeal Carcinoma Screening
The investigators intend to compare Epstein-Barr virus antibody and Epstein-Barr virus DNA screening efficacy in first-degree relatives of nasopharyngeal carcinoma patients.
Artificial Intelligence (AI) Analysis of Synchronized Phonocardiography (PCG) and Electrocardiogram(ECG)
The diagnosis of depressed left ventricular ejection fraction (dLVEF) (EF<50%) depends on golden standard ultrasound cardiography (UCG). A wearable synchronized phonocardiography (PCG) and electrocardiogram (ECG) device can assist in the diagnosis of dLVEF, which can both expedite access to life-saving therapies and reduce the need for costly testing.
A Study to Assess the Long-Term Safety of Ustekinumab Versus Other Biologics in Patients With Crohn's Disease and Ulcerative Colitis
The purpose of this study is to estimate and compare the incidence of overall malignancy, serious infection, and opportunistic infections between new users of ustekinumab and new users of other biologic therapies among adult participants with Crohn's disease (CD) or ulcerative colitis (UC).
The Impact of Radiotherapy on Oligometastatic Cancer
Metastases represent the most threatening challenge in cancer. One of the management strategies for patients with Oligometastatic Cancer (OC) is Stereotactic ABlative Radiotherapy (SABR). However, there are few studies, and there is no defined clinical standard, nor are the radiobiological mechanisms that contribute to treatment response well understood. The focus …
Antenatal and Postnatal Care Research Collective - Household Survey (ARCH)
The overarching goal of the ARCH Survey is to establish a prospective longitudinal pregnancy surveillance study in Lusaka, Zambia, to precisely characterize the pregnancy rate and outcomes of women of reproductive age prior to, during, and following pregnancy and to investigate the structural, sociodemographic, and clinical covariates that contribute to …
Early Detection and Screening of Hematological Malignancies - SANGUINE
This is a multicenter, open-label, non-interventional controlled study to identify and characterize the epigenetic signatures for a set of hematological malignancies: Multiple myeloma (MM), pre-MM conditions [smoldering MM (SMM) and monoclonal gammopathy of undetermined significance (MGUS)], Hodgkin lymphoma (HL), non-Hodgkin aggressive lymphoma NHL [diffuse large B cell lymphoma (DLBCL), follicular …
Pathophysiological Endotyping Using Baseline Polysomnography Data
The study is designed to develop models to predict site of collapse information using routine polysomnography. In an observational study, the investigators will study 1000 patients with obstructive sleep apnea (OSA) who have had a recent polysomnographic study and will undergo drug-induced sleep endoscopy (DISE) as part of their standard …
Investigating Genetic Status in Patients Presenting to Clinic
The causes of neurodegenerative dementias such as Frontotemporal Dementia, Lewy Body Disease and Alzheimer's disease are still largely unknown. While the contribution of some genetic mutations and polymorphisms is associated with autosomal dominant patterns of inheritance of these dementias, in many cases, the specific causative mutation in these families is …
Williams Syndrome (WS) and Supravalvar Aortic Stenosis (SVAS) DNA and Tissue Bank
Williams syndrome is a rare genetic disorder occurring in 1:8000-12,000 individuals. It is caused by the deletion of 25-27 coding genes, including elastin (ELN) on the 7th human chromosome. Haploinsufficiency for these genes leads to the features of the condition, including Distinctive facial features; Characteristic vascular problems including hypertension, focal …
