Filter by: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 is a retrospective, proof of concept study, which aims at reconstructing the cellular heterogeneity of the tumor in multi-needle diagnostic prostate biopsy as well as any biopsy containing potentially pre-malignant tissue, to study its implications in the clinical history of the disease. For each patient, 2 or more samples will be prepared starting from the FFPE diagnostic material. The biopsy used for assigning the Gleason score will be sequenced, together with two or more of the local peri-proximal biopsies with a higher level of differentiation. Samples will undergo Whole Exome Sequencing with an average coverage of 300x at the Wellcome Sanger Institute (WSI, Hinxton, UK). Sequencing data will be analysed for single nucleotide variants, copy number variants and structural variants by using state-of-the-art data analysis pipeline at WSI. 1. Reconstruction of local PCa heterogeneity in multi-needle diagnostic biopsy with different Gleason scores (6-10) using high-coverage whole exome sequencing (WES) and DP-based clonal analysis; 2. Characterization of the relationships between pathological differentiation (Gleason score) and genomics-measured heterogeneity and malignancy features; 3. Assessment of clinical implications of clonal heterogeneity. The study will include an average of 150 prostatic diagnostic biopsies from a cohort of 20 early metastatic PC patients and 20 non-relapsing/non-metastatic patients with indolent malignant disease.
The participants are being asked to take part in this research study because the participant is a child who has been diagnosed with cancer and has completed genetic testing to find out if the participant has a variant in a gene that may predispose the participant to cancer, and/or the participants are the parents (i.e., guardian/caregiver) of this child. This research is being done to understand how finding out the results of genetic testing during childhood impacts the participant and family. The investigator will compare the emotions and behavior of parents and children based on the genetic testing results. Primary Objective - Examine the impact of genetic testing result disclosure for a pathogenic (P)/likely pathogenic (LP) germline variant in a known cancer predisposing gene versus negative results on parent adjustment (i.e., emotional functioning, cancer worry, symptom interpretation, and genetic testing related worry/distress). - Examine the impact of genetic testing result disclosure for a P/LP germline variant versus negative results on parenting (i.e., responses to children's symptoms, overprotectiveness, parent-child communication, cohesion, and expressivity in the family). Exploratory Objectives - Examine the impact of genetic testing result disclosure (P/LP versus negative results) on child adjustment (i.e. emotional functioning, cancer worry, self-perception, and life meaning and purpose). - Examine the impact of disclosing a variant of uncertain significance (VUS) on parent adjustment, parenting, and child adjustment. - Examine the indirect association between genetic testing result disclosure (P/LP versus negative results) and child adjustment through parental adjustment and parenting behavior. - Qualitatively identify children and parents' perspectives of how disclosure of a cancer predisposition has affected children's emotional, social, personal, and familial functioning.
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.
A cluster randomized controlled study of 40 primary care clinics in Northern Israel (20 intervention clinics, 20 usual care clinics) to evaluate the value of introducing a precision medicine/genomic approach/paradigm on the clinical and economical outcomes of the clinics. Intervention includes 3 elements: 1. DNA extraction and evaluation (up to the level of WGS); 2. Feces sample for microbiome study, 3. Wearable devices for continuous monitoring of body functions. Expected number of participants is 100,000 in each arm. Results will be calculated for a clinic as a unit and not for individuals (each clinic to be compared to "twin" selected clinic).
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.
The study aims to investigate SARS-CoV-2 susceptibility, transmission and disease severity in healthcare workers and patients. Residual specimens from an existing collection of samples in viral inactivating buffer and derivatives and serum from the Crick COVID-19 Consortium Testing centre (Cohort A1) and additional biological material collected prospectively (Cohorts A2 and B) will be used for research into SARS-CoV-2 transmission, evolution and immune control. This testing centre is a partnership between UCLH and The Francis Crick Institute to provide COVID 19 RT PCR testing for healthcare workers (HCWs) and patients in London Hospitals and care homes. A third group (Cohort C) of the study will allow for collaborative work with other REC approved research studies that have used the Crick COVID-19 Consortium Testing centre and will involve the use of study samples already collected from each study to be analysed under the SARS-CoV-2 Longitudinal Study end points
Although epidemiological studies have associated the consumption of sugary beverages with adverse health effects, experimental studies have demonstrated that the metabolic response of the human body to fruit juice as compared to artificial beverages is substantially different. Fruit juices do not just provide sugars and related calories, but they are rich sources of bioactive compounds especially of flavonoids. Flavanones constitute a class of flavonoids that are specifically and abundantly found in citrus fruits, with hesperidin being the major compound in orange. From prospective cohort studies, higher intakes of flavanones are associated with a lower incidence of mortality by cardiovascular disease (CVD). This relation is supported by results from a number of animal studies demonstrating a slowdown in atherosclerosis development and vascular protective effects in dietary interventions with flavanones. Randomized, controlled clinical trials to corroborate the suggested vasculo-protective effects of orange juice presumably mediated by the flavanones are scarce and available data do not allow to draw firm conclusions about their efficacy. To fill this gap, the "HESPER-HEALTH study" conducted in humans will assess the vascular protective effects of 100% orange juice consumption and evaluate the contribution of hesperidin in these effects.
For the retrospective data analysis, patients with genetic diseases of any age and, if available, other family members, for whom genetic analyzes were carried out between 10/2016 and 12/2020, should be included. This equates to approximately 13,000 records, minus combined analyzes in the same patient, an estimated 12,000 individuals.
