Filter by:This 2-arm prospective, randomized, controlled clinical trial compared outcomes of telephone genetic counseling (intervention) versus in-person genetic counseling (control) in an underserved, multilingual patient population referred for cancer genetic counseling at two North Texas safety-net hospitals. The main question[s] it aims to answer are: - Is telephone genetic counseling equal to in-person genetic counseling in the patient reported outcomes? Cancer genetics knowledge, attitude towards GT, and informed choice as well as GC-specific empowerment. - Is telephone genetic counseling-based clinical outcomes the same as in-person genetic counseling for visit completion and testing rates? Participants will be randomized to either in-person or telephone genetic counseling arm and complete standard of care genetic counseling visit process where testing is offered. Both arms will complete a series of surveys to assess the outcomes of interest.
Genetic polymorphism on the effect of oral caffeine intake on fat oxidation during exercise has been studied in active and healthy population performing an incremental test on a cycle ergometer with 3-min stages at workloads from 30 to 70% of maximal oxygen uptake (VO2max). Participants performed this test after the ingestion of a) placebo; b) 3 mg/kg of caffeine; c) 6 mg/kg of caffeine. Fat oxidation rate during exercise was measured by indirect calorimetry. The influence of the CYP1A2 c.-163A>C, GSTP c.313A>G and PGC1a polymorphisms was evaluated to determine the effects on fat oxidation during exercise
The role of Sentinel Lymph Node Biopsy(SLNB) among mutation-negative BC patients is well established; however, we are lacking data to assess the role of sentinel lymph node biopsy for patients who are undergoing surgery for prophylactic reasons without proven malignancy. Literature has reported a positive Occult Breast Cancer (OBC) rate of 0 to 11.3% among mastectomy specimens which are removed prophylactically. Majority of the time when the invasive focus is diagnosed in prophylactic mastectomy specimens they are found to be in-situ cases where axillary Staging using SLNB can be exempted; however, when the OBC is identified even in prophylactic mastectomy specimens, axilla should be addressed accordingly. Albeit SLNB has associated complications with it; postoperative pain, lymphedema, paresthesia and rare reaction to the injected dye. Therefore the question here arises regarding skipping SLNB among patients who are undergoing PRRMs without proven malignancy pre-operatively. However, before standardizing the practice in our population we need convincing evidence that the frequency of OBC is low among our patients. By identifying the true prevalence of OBC among our gene-positive HBC patients who are opting for PRRM, we would be able to skip SLNB; as not only it has psychological implications but also adds a financial burden on patients and families due to the addition of an extra procedure and hospital bills; as the financial and socioeconomic status of our population has already declined over last few years due to the economic crises faced worldwide, specifically after-affects are seen in Lower Middle-Income Country(LMIC) like Pakistan.
This is a retrospective analysis of data collected within two previous studies. The data has been combined and used to investigate the impact of having a family history of hypertension on left ventricular muscle mass with and without controlling for moderate and vigorous intensity physical activity frequency per week. The hypothesis was that in a sample of mostly active participants, no differences in left ventricular mass between family history of hypertension groups would be observed, but the positive family history of hypertension group would have elevated left ventricular mass compared to the negative family history of hypertension group following statistical control of activity frequency.
A total genotype risk score was generated based on the findings of previous research for non-contact injury, non-contact muscle injury, tendon injury, ligament injury, fracture injury and apophysitis injury. This score was then compared with the incidence of injury between those with high, medium and low risk scores for each injury. The influence of different rates of growth, stages of physical maturation and loading exposure were then also included in the risk model to see if any interaction effects could be observed between genetic risk score and susceptibility to injury in different categories of growth, maturation and loading exposure.
This project aims to assess if food choice is impacted by loss aversion (LA), and if this differs based on genetic predisposition to LA, in a UK healthy cohort.
The study intervention involves having patients complete a familial cancer risk assessment survey. Those who are found to be at high risk will be offered genetic testing for a panel of hereditary cancers. A "previvor" plan will be created to assist patients and their providers in completing the appropriate follow-up for those with a mutation identified.
This study investigates the association of genetic effects of rs7903146 and dietary intake on type 2 Diabetes Mellitus (T2DM) risk in a healthy population. T2DM risk was assessed through glycated haemoglobin (HbA1c) concentration in 73 subjects. Dietary intake was assessed using a validated food frequency questionnaire (FFQ).
The Jewish Population is at an increased risk for genetic diseases, especially autosomal recessive, thus, screening should be done to determine carrier status of several genetic diseases. In the Mexican Jewish Community, which is a very diverse community (regarding geographical origins), data of carrier status is unknown. The study aims to determine carrier prevalence for over 300 diseases using commercially available panels.
Studies have shown that the effect of fat mass and obesity-associated (FTO) gene on obesity is modulated by lifestyle factors. Hence, we aimed to determine whether two single nucleotide polymorphisms (SNPs) in the FTO gene are associated with obesity and to assess whether these associations were modified by lifestyle factors. The study included 200 obese and 200 non-obese individuals from Turkey. Our study suggests that the effect of the SNPs on obesity traits is likely to be influenced by lifestyle factors in this Turkish population.
