Filter by:Acute pancreatitis (AP) is a multifactorial disease. AP represents a significant number of hospital admissions. Most of the patients are admitted in an acute setting. Early identification of its etiology is an essential step toward the rational approach, both for its implications in the immediate therapy and the prevention of recurrence. Although often obvious, the etiological workup of acute pancreatitis can be challenging.
The study "Investigating the Feasibility and Implementation of Whole Genome Sequencing in Patients With Suspected Genetic Disorder" is a research study that aims to explore the use of whole genome sequencing as a potential first line genetic test for patients for which a genetic diagnosis is suspected. This is an internally funded research study. The investigators will enroll 500 participants who are being seen in one of the various genetics clinics within the Partners HealthCare system for a suspected genetic disorder for which standard-of-care genetic testing is ordered. At the time of their standard-of-care genetic testing, an extra blood sample will be collected, and genome sequencing may be performed. Within 3-4 months, patients learn if they received genome sequencing or not, and any results are returned and explained. Investigators are also studying the experiences of both participants and their providers to better understand how to implement genome sequencing into clinical care.
The objectives of this trial are to assess the effects of interactions between genetic factors and diet with various macronutrient intake on the metabolic disorders, obesity and type 2 diabetes risk, prevention, development and progress.
This research aims to investigate how exposure to advertising for Electronic Nicotine Delivery Systems (commonly called e-cigarettes) may lead to combustible smoking initiation in adolescents.
The aim of this study is to examine the interindividual variability of subjective and hormonal appetite responses to a standardised meal in healthy men and explore any moderating influence of the fat mass and obesity associated gene (FTO). Participants homozygous for the obesity risk A allele (AA) or low risk T allele (TT) of FTO rs9939609 will complete two fasted control and two standardised meal (5025 kJ energy, 47% carbohydrate, 9% protein, 44% fat) conditions in randomised sequences. Ratings of perceived appetite and venous blood samples will be taken before and after the interventions. Interindividual differences in appetite responses and the potential moderating influence of the FTO gene will be examined using bivariate correlations and linear mixed modelling.
Cohort of subjects carrying a BRCA gene mutation: genetic predispositions to breast and ovarian cancers
The purpose of this study is to assess efficacy of 14-day antimicrobial susceptibility test guided quadruple therapy for the rescue treatment of Helicobacter pylori infection, then comparing it with 14-day empirical therapy according to personal medication history.
Nausea and vomiting affects 25-30% of individuals in the post-operative period and can reach more than 70-80% in high-risk patients. inherited factors may play a significant role in individual susceptibility and clinical research on hereditary factors involved in the pathogenesis of Postoperative nausea and vomiting (PONV) and chemotherapy nausea and vomiting (CINV) is relatively new. The aim of this study is to investigate whether inter-individual differences related to PONV are associated with genetic factors. 300 patients will be evaluated in postoperative oncological surgeries. The peripheral leukocyte DNA will be extracted by the Salting Out Procedure method and processed to genotyping for 48 SNPs from 15 candidate genes by real-time PCR by the Taqman method. The possible associations with demographic data and factors related to surgery will be analyzed by univariate and multivariate analysis.
Three candidate single nucleotide polymorphisms in the RORC2 gene, rs9826 A/G, rs3790515 C/T and rs3828057 C/T were examined together with estimation of nuclear hormone retinoic acid receptor-related orphan receptor variant 2 serum levels to determine their possible association with susceptibility to and clinical phenotype of rheumatoid arthritis in Egyptian population.
Antibiotic resistance is a serious and increasing worldwide threat to global public health. One of antibiotic stewardship programmes' objectives is to reduce inappropriate broad-spectrum antibiotics' prescription. Selective reporting of antibiotic susceptibility test (AST) results, which consists of reporting to prescribers only few (n=5-6) antibiotics, preferring first-line and narrow-spectrum agents, is one possible strategy advised in recommendations. However, selective reporting of AST has never been evaluated using an experimental design. This study is a pragmatic, prospective, multicentre, controlled (selective reporting vs usual complete reporting of AST), before-after (year 2019 vs 2017) study. Selective reporting of AST is scheduled to be implemented from September 2018 in the ATOUTBIO group of 21 laboratories for all E. coli identified in urine cultures in adult outpatients, and to be compared to the usual complete AST performed in the EVOLAB group of 20 laboratories. The main objective is to assess the impact of selective reporting of AST for E. coli positive urine cultures in the outpatient setting on the prescription of broad-spectrum antibiotics frequently used for urinary tract infections (amoxicillin-clavulanate, third generation cephalosporins and fluoroquinolones). The primary endpoint is the after (2019) - before (2017) difference in prescription rates for the previously mentioned antibiotics/classes that will be compared between the two laboratory groups, using linear regression models. Secondary objectives are to evaluate the feasibility of selective reporting of AST implementation by French laboratories and their acceptability by organising focus groups and individual semi-structured interviews with general practitioners and laboratory professionals.
