Chronic Venous Disease (CVD) is a widespread clinical condition widely spread in the western countries that may negatively impact the quality of life (QoL) of affected patients. Chronic venous leg ulcers (CVLUs) are the most severe form of CVD, and several genetic and molecular alterations have been studied in order to understand the progression of CVD towards CLVUs. Chronic inflammation is a key element in CVLUs onset, and recently T helper 17 (Th-17) cells, a subtype of pro-inflammatory T helper (CD4+) cells defined by the production of a cytokine signature of which IL-17 represents the progenitor, seem to be related to several chronic disease. The aim of this study is to evaluate Th17- Gene Expression profile in patients with CVD and CVLUs.
The purpose of this study is to track changes in the brain related to Alzheimer's disease. The results from this study will be used to develop new approaches to prevent or delay the onset of memory and thinking problems associated with Alzheimer's.
VISAGE-ONCO study is a qualitative transversal study aiming to identify and describe processes and mechanisms that explain in cancerology the feelings and experience of patients and health professionals with regard to the possibility of having access to secondary findings generated by the use High-speed exome sequencing . Semi-structured interviews will be conducted with patients and health professionals to answer this aims from 2 situations. The first situation is in the context of the standard practice for theranostic purposes, where somatic and constitutional analysis of the various genes involved in carcinogenesis is carried out systematically in parallel. Patients are informed that the analysis of these genes may reveal the existence of a genetic predisposition to another type of cancer than the one for which patients have consulted, with a risk for themselves or their relatives, which could modify their management. This targeted information on genetic predisposition genes to cancer is therefore provided as part of standard management for theranostic purposes, but without any detailed exploration of the reasons why patients wanted to be informed. The second situation is in the framework exome analysis position in the strategy of genetic redisposition factors identification in early-onset cancer study (EX²TRICAN NCT04141462) where all the genes identified in human pathology are part of the analysis. Patients have the possibility of accessing a result concerning a gene that may or may not be linked to a hereditary cancer risk if patients have ticked off in the consent form the wish to be informed. Therefore, two distinct questions arise: - That of understanding the wish of patients to be given back actionable data which can be identified in a fortuitous way within the framework of standard management for theranostic purposes and in EX²TRICAN, by taking into account the fact that these data can constitute an opportunity for the patient in terms of management; but patients also constitute a risk of transmission for they relatives, and a psychological risk by the anxiety generated; - The wish to have access - or not - to data which are not actively sought today within the framework of standard care for theranostic purposes and in EX²TRICAN (genetic alterations increasing the risk of cardiovascular or metabolic diseases), but which could be proposed in a systematic way in the future because of their actionable character.
Assessment of the utility of family-based (trio) whole-genome sequencing for cancer predisposition testing in sequential newly diagnosed paediatric and adolescent cancer patients
Early stage high-grade cancer, endometrial and ovarian, has few, if any, symptoms or signs. When symptoms appear, the disease may be in advanced stage as the disease has left the gynaecological organs and metastasized to the pelvic/abdominal cavity. The McGill research group had showed in the DOvEE trial (NCT02296307), that fast-track assessment with transvaginal ultrasound scans (TVUS) and serial CA125 of women with vague symptoms associated with ovarian and endometrial cancer did diagnose these cancers earlier in the disease trajectory, with low-volume resectable disease, but only after the cancer had already become Stage III. One way to detect these cancers earlier is to screen asymptomatic women. Unfortunately, none of the currently available tests, including TVUS and CA-125 have been shown to be useful for screening for ovarian or endometrial cancer. The McGill team has developed a genomic assay to screen and detect these cancers earlier in the trajectory than is currently the case. The test identifies pathogenic somatic mutations (necessary early steps in the development of these cancers), in an uterine cytological sample. It is able to do so by incorporating a deep machine-learning derived classifier that can discriminate the mutational signature of these cancers from benign disease with a sensitivity of 70% and a specificity of 100% in a population with high background mutational burden. In addition to the intra-uterine cytological sample, the test includes an assay of a saliva sample to identify germline mutations that predispose to hereditary endometrial/ovarian cancers as well as breast and colon cancers. The test was developed in a retrospective population in whom the assay was done pre-operatively and the diagnosis of malignancy versus benign gynecological disease was confirmed by detailed pathological analysis of the uterus, tubes, and ovaries after surgical resection (NCT02288676). The test is now ready to be tested as a phase III diagnostic test in the general population to see if these results are just as promising in the community at large.
This study aims to determine the effects of communicating genetic risk for type 2 diabetes (T2D) alone or in combination with goal setting and prompts from a wearable device on objectively measured physical activity (PA) and sedentary behavior (SB) in East Asians. It is hypothesized that this combination will lead to significant favorable changes in objectively measured PA and SB, and that such changes will be more likely to be sustained over 6-month follow-up. This study aims to recruit 150 healthy East Asian adults in Hong Kong. At baseline, participants will be invited to visit the research laboratory for measurement of a series of variables including height, body weight, blood pressure and grip strength. Participants will also be invited to complete a set of questionnaires to assess their self-reported PA and SB, fruit and vegetable consumption, smoking status and psychological variables. Blood samples will be collected to analyze key diabetes and cardiovascular disease biochemical markers as well as their estimated genetic risk of T2D. Each individual's unique genetic risk for T2D will be estimated on the basis of established genetic variants associated with T2D specifically for East Asians. Each participant will be asked to wear a Fitbit Charge 4 tracker, an objective activity monitoring device, throughout the entire trial. Participants will be randomly allocated into 3 groups: 1 control and 2 intervention groups. A control group will receive an e-leaflet containing general lifestyle advice for prevention of T2D. An intervention group will receive an estimated genetic risk of T2D, in addition to the e-leaflet. The other intervention group will have a Fitbit step goal set 10% higher than their baseline step count and use prompt functions of the Fitbit tracker, in addition to the genetic risk estimate and e-leaflet. Activity data from the Fitbit will be collected at 4-week post-intervention; information about lifestyle and psychological variables will be assessed through the questionnaires at both immediate and 4-week post-intervention. To determine the longer-term effect of the intervention, participants will be asked to visit the research laboratory 6 months after the intervention to repeat the same set of assessments as baseline, except the blood samples collected at 6-month follow-up are used only to analyze cardiometabolic risk profiles (not genetic risk). Activity levels will also be objectively measured using the Fitbit for 4 weeks.
This research will have a significant impact on the overall management of those cancer patients and their family members who are at risk for hereditary cancer due to germline inactivation of BAP1. Our study will ultimately facilitate the development of novel screening, prevention and treatment strategies for these individuals with the syndrome. Because the vast majority of UM develop in pre-existing nevi, characterization of individuals at high risk for development of UM will allow closer screening and earlier intervention which would improve the treatment outcome not only for retaining vision but also for overall survival. Similarly in patients with germline BAP1 mutation CM develops in premalignant atypical melanocytic lesions and careful follow up of these patients will improve the outcome of their disease. In addition this study could have impact on the management of patients with personal and/or family history of several other cancers reported in patients with germline BAP1 mutation such as mesothelioma, renal cell carcinoma, cholangiocarcinoma, hepatocellular carcinoma, meningioma and basal cell carcinoma.
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.
The GE-MED APPROACH project will enroll patients (n = appr. 12.000) with unclear molecular cause of the disease, suspected genetic cause of the disease without detailed molecular analysis like Whole Exome Sequencing (WES). The novelty of this study is to integrate genomic health concepts into immediate clinical care. To achieve these goals, a novel structure for the Triple P (3P) concept of personalized medicine (Personalized, Predictive, Preventive) integrated into a well-established health care system and associated with novel decentralized Disease Analysing Task Forces (DATF) will be implemented. The overall goal of this study is to implement, for the first time, Whole Genome Sequencing (WGS) analysis as a first line diagnostic test for all clinical indications such as Rare Disease (RD )and familial cancer syndromes.
