Gout is a chronic disease caused by the deposit of monosodium urate (MSU) crystals in body tissues secondary to hyperuricemia. Patients with gout suffer severe attacks of acute joint pain. As the disease progresses, the joint pain becomes chronic and associated with disabling and deformative manifestations called tophi. Gout is strongly associated with various comorbidities including cardiovascular disease and chronic kidney failure. Gout is a very common disease, affecting 0.9% of the adult population in France and nearly 4% of the North-American population. Data from New Zealand show a particularly high prevalence of gout among Polynesians (minority populations in New Zealand and other islands of the South Pacific) that would be explained by genetic susceptibility and frequently intertwined with metabolic diseases. Recent findings obtained from the Polynesian population in New Caledonia disclose high prevalence figures close to 7%, a level expected to be confirmed by an epidemiology study that will be conducted in parallel with the present study and designed to determine the precise prevalence of gout in French Polynesia and the most frequently associated genetic variants.

An international, multicenter study to identify tumor molecular particularities and neoepitopes among participants with colorectal and pancreatic tumors undergoing surgery.

The investigators will approach elective cardiac and thoracic surgery patients in the preoperative consultation clinic. Consenting individuals will be administered, before surgery validated pain, psychological and sleep questionnaires. These questionnaires will be repeated at 3, 6 and 12 months postoperatively (PO) to follow up the progression of early PO pain and the transition to chronicity. Participants will define clinically relevant pain by calculating a chronic pain index (CPI). In addition, the investigators will follow the development of acute postsurgical and chronic pain from before surgery up to a year after, extract DNA from blood and contrast the genetic variations of participants with clinically significant chronic pain, to identify variations associated with the development of chronic post-surgical pain.

Many human populations across the world are deficient in the intake of dietary fiber. This decline in fiber consumption parallels an increase in prevalence of a multitude of diseases (e.g. colorectal cancer, multiple sclerosis). A possible link for this association between dietary changes and the diseases could rest in the trillions of commensal gut microbes that digest dietary fibers, provide energy for colonic cells, and modulate the immune system. However, the molecular mechanisms that link fiber deficiency via the activities of the gut microbiome to various diseases have been poorly understood. The investigators previously showed that, in a mouse model with a defined human gut microbiota, removal of fiber from the diet favors proliferation of bacteria that degrade the gut's protective mucus lining. In the proposed project, the investigators aim to translate our findings from mouse studies to humans using a 2x2 crossover study among healthy adults. Forty participants will be randomly assigned to a low- or high-fiber dietary intervention and then, following a washout period to reverse any changes, switched to the other diet type. By employing longitudinal sampling of stool collections, the investigators envision that participants will exhibit increased abundance and activities of mucolytic bacteria when fed a low-fiber diet. The unique selling point of the proposed study involves setting up high-throughput culture collections of mucus-degrading bacteria, whose abundances and activities will be investigated by sequencing and enzymatic assays in stool. Additionally, the investigators will measure inflammatory markers in blood using CyTOF to assess whether short-term fiber deficiency exerts detectable changes in the host immune function. Thus, the proposed dietary intervention clinical trial will help elucidate the role of fiber deficiency in various chronic diseases.

The Study Objective is to evaluate the diagnostic efficacy of the liquid biopsy system versus the gold standard mammography (or MRI, or Ultrasound) diagnosis in patients with suspected breast cancer.

Malaria in pregnancy (MiP) continues to be a significant public health issue, particularly in sub-Saharan Africa. The coverage of pregnant women with three or more doses of intermittent preventive treatment using sulphadoxine-pyrimethamine (IPTp-SP) is recommended to prevent risks associated with MiP in moderate-to-high transmission settings. Evidence has recently become available supporting the emergence of a novel Pfdhps-431V mutation in Nigeria. This new mutation may further confound the existing SP-resistance; thus, the intended follow-on project aims to assess the influence of Pfdhps-431V mutation on the protective efficacy of SP during pregnancy. The aims are to detect P. falciparum positivity at delivery and pregnancy outcome in participants who must have received three or more doses of IPTp_SP. We will attempt to check the presence of existing and new Pfdhps/Pfdhfr mutations in the samples positive for P. falciparum using a quantitative PCR (qPCR). The prevalence of novel Pfdhps-431V mutant and other Pfdhps/Pfdhfr resistance alleles among the study population will be estimated. The significance of the resistance genes on the efficacy of SP will be described by looking at its associations with the reported IPTp use, P. falciparum infection, maternal anaemia, low birth weight, and preterm delivery.

The objective of the Gestational Diabetes Genetic Socioeconomic Risk Study is to generate genome wide association study data (GWAS) to calculate polygenic risk scores (PRS) for the development of gestational diabetes in pregnant women. Oshun Medical's GWAS study will be conducted by collecting DNA samples alongside medical and socioeconomic data and applying data science methodology to generate a polygenic risk score algorithm for gestational diabetes. Our hypothesis is that key genetic variants linked to gestational diabetes will be identified, and sociodemographic characteristics may impact epigenetic factors which further contribute to this risk of gestational diabetes. The PRS generated through our study will be combined with an analysis of epigenetic factors to produce a new method for predicting risk of developing gestational diabetes during pregnancy.

A prospective and retrospective cohort study of patients with a documented pathogenic or likely pathogenic variants of TP53 were identified using blood DNA colection and breast cancer diagnosis by histological confirmation, between 1999 and 2022. All patients were followed by the Hereditary Group of a single cancer center (Instituto do Cancer do Estado de Sao Paulo). Patients were included if they had a histopathological diagnosis of localized invasive carcinoma or in situ carcinoma of the breast and with localized disease. Patients met Revised Chompret criteria, Li Fraumeni like syndrome,family member of carrier TP53 or hereditary breast and ovarian syndrome for germline test.

The aim of the joint project PROVID is to contribute to better outcome prediction for COVID-19 patients, to better clinical management, and to the development of new therapies. To this end, the investigators will collect detailed data on the course of COVID-19 patients and deeply characterize them at the molecular level. The investigators also aim to identify compounds with the potential to improve outcome. The PROVID-PROGRESS study is being carried out as a prospective, longitudinal, multicenter observational study (case cohort study) with material asservation for genomic, transcriptomic and proteomic analyzes on adult patients with COVID-19.

Patients with Carcinoma of Unknown Primary (CUP) have widespread cancer at diagnosis however the specific site of origin cannot be found, despite significant testing, making it difficult to treat. CUP has a poor prognosis; it is the 6th most common cause of cancer death in the UK. To date there have been limited studies investigating molecular genomics in CUP patients, resulting in limited evidence to evaluate whether genomic profiling has added value over and above the standard diagnostics provided in the NHS. As a result, our project will aim to; - Assess genomic sequencing (both in tissue and blood) for the diagnosis and treatment guidance in CUP patients including a comparison of the effectiveness of tissue and blood based biomarkers - Collect evidence to further develop technology that predicts an individual's response to a treatment - Develop innovative systems of clinical data capture in patients with CUP - Investigate novel biomarkers to determine the primary tumour location Approximately 120-140 CUP patients will be recruited across 7 UK NHS sites. Tumour samples will be collected from patients undergoing a standard of care procedure OR medically fit patients with accessible tumour. Archival tumour may also be obtained. Some samples will be stored for future translational research. Sequencing results alongside clinical data will be discussed by a multi-disciplinary CUP Molecular Tumour Board. They will provide oversight on the nature, clinical significance and relevance of the results. They will inform the local CUP team of any "actionable" genetic changes, which could potentially direct selection of a targeted therapy trial for that patient. Sequential blood samples will be collected to investigate genetic characteristics that may be able to predict response to therapy. The aggregated anonymised data will be made publicly available following completion of this trial.

The first part (Part 1) is a Phase I dose-escalation, 3+3 design, open-label, MTD determination study and will enroll patients who have tumors known to harbour DNA repair deficiencies. The second part (Part 2) is a Phase Ib, dose-expansion at the MTD (or optimal dose) and will enroll patients with a confirmed deleterious HRR mutation in their tumor as identified by a central genomics testing laboratory.

The Health in Aging, Neurodegenerative Diseases and DementiaS in ONTario (HANDDS-ONT) Study is an observational study that takes place in the comfort of participant's home, with no study visits occurring in a clinic. The study is recruiting people living with a neurodegenerative disease or the effects of stroke, along with healthy, aging individuals. Studying both groups will help ONDRI researchers to: 1. understand how the diseases affect different people 2. discover ways to potentially detect diseases earlier 3. find ways to help people manage their daily health related behaviours Participant data is collected virtually through wearables - small sensors worn on the wrist, ankle and chest -- for 7-10 days, as participants go about their daily activities. Data is also collected from questionnaires regarding mood and quality of life. Blood samples will be collected to understand how one's genetic makeup could provide for earlier detection of some conditions, and for analysis of certain risk factors. Combining the information from the sensors (walking patterns, sleep, heart rate/rhythm, etc.), the questionnaires and the blood samples will allow researchers to better understand aging, with and without a neurodegenerative condition, over a period of time. Participants will receive a personalized health and activity report, describing sleep and activity during the time the wearable sensors were worn. This information may help participants better understand and manage some aspects of their overall health and it can be shared with their circle of care.
