GI Biorepository of Tissue and Bodily Fluids
Gastrointestinal DiseasesThe purpose of this study is to establish the working protocols for a general biorepository with the specific aim of procuring tissues and bodily fluids from the human gastrointestinal tract from a diverse range of clinical patients at the UC Davis Medical Center. The establishment of a GI-specific biorepository will support future translational endeavors within the UC Davis campus by providing laboratories with readily available GI tissue and bodily fluid samples to test newly developed hypotheses with relative ease.

Diagnosis of Neglected Tropical Diseases Among Patients With Persistent Digestive Disorders
Soil-transmitted HelminthiasisSchistosomiasis9 moreNIDIAG is an international collaboration on integrated diagnosis-treatment platforms, funded by the European Commission (EC). NIDIAG aims to develop an improved, patient-centred system for delivering primary health care in resource-constrained settings. NIDIAG will investigate three clinical syndromes, namely (i) persistent digestive disorders, (ii) persistent fever and (iii) neurological disorders, due to neglected tropical diseases (NTDs). The current study focuses on persistent digestive disorders, which are defined as diarrhoea or abdominal pain that last for at least 2 weeks. While acute diarrhoea has been studied globally, few research activities have focused on the epidemiology, diagnosis and treatment of long-lasting diarrhoeal episodes (2 weeks and longer) in the tropics. The spectrum of possibly involved pathogens includes more than 30 bacterial, parasitic and viral infectious agents. This lack of data may be explained by the fact that people suffering from NTDs might only seek care at a late stage of the disease. Furthermore, health systems in affected regions are often weak and their primary health-care centres are often under-staffed and lack essential diagnostic equipment. The hypothesis of this study is that development of an evidence-based syndromic approach can lead to better diagnosis and management of NTDs in patients with persistent digestive disorders. The study will be carried out in two West African countries (Côte d'Ivoire and Mali) and in two Asian countries (Indonesia and Nepal). The study will follow a "case-control" design and patients and controls will be prospectively enrolled. In order to address the knowledge gaps, three specific objectives will be pursued. First, the contribution of NTDs to the 'persistent digestive disorders syndrome' will be assessed. Second, the value of clinical features and rapid diagnostic tests (RDTs) for the diagnosis of target NTDs that give rise to persistent digestive disorders will be determined. Third, the clinical response to standard empiric and targeted treatment of several NTDs in patients with persistent digestive disorders will be evaluated. These objectives will provide a long-term benefit for the communities by improving the clinical decision-making process for the target NTDs and thus, better diagnostic work-up and patient management can be achieved in the study countries and other similar resource-constrained countries

Blood Pressure During ESD is Related With the Postoperative Bleeding
Gastrointestinal DiseaseGastrointestinal BleedingEndoscopic submucosal dissection(ESD) is a prominent minimally invasive operation technique for treating early gastrointestinal tumor. But promoting ESD is uneasy because of its complications such as postoperative bleeding, perforation and so on. So if we decrease the rate of postoperative bleeding, ESD might be better popularized. Some study indicated that hypertension was the independent risk factor of postoperative bleeding. Endoscopic center of Fudan University Zhongshan Hospital is a rich experienced medical unit in doing ESD operation in China. Referring to our experience, if we can use some special methods to find the potential bleeding spot which is not obvious during ESD operation and we coagulate it precisely, then we may control the risk of postoperative bleeding. Based on the above hypothesis, our team designed this study to examine whether increasing blood pressure during gastric ESD could help to control the risk of postoperative bleeding.

Urinary Tract InfectionsInfectious Diarrhea3 moreThe purpose of this study is to assess the feasibility of TrueLoo™, an Internet-connected smart toilet seat, in accurately monitoring and logging bowel movements and urinations of residents in senior living facilities across Northern California.
Screening and Identifying Hepatobiliary Diseases Via Deep Learning Using Ocular Images
OphthalmologyArtificial Intelligence1 moreArtificial Intelligence may provide insight into exploring the potential covert association behind and reveal some early ocular architecture changes in individuals with hepatobiliary disorders. We conducted a pioneer work to explore the association between the eye and liver via deep learning, to develop and evaluate different deep learning models to predict the hepatobiliary disease by using ocular images.
Cohort of Swedish Men
CancersCardiovascular Diseases4 moreThe Cohort of Swedish Men began in 1997, when all men born between 1918 and 1952 and residing in two counties in central Sweden received a questionnaire including about 350 items concerning diet and other lifestyle factors. A second questionnaire was sent out in 2008-09.
