In the Ashkenazi Jewish (AJ) population of Israel, 11% of breast cancer and 40% of ovarian cancer are due to three inherited founder mutations in the cancer predisposition genes BRCA1 and BRCA2. For carriers of these mutations, risk-reducing salpingooophorectomy significantly reduces morbidity and mortality. Population screening for these mutations among AJ women may be justifiable if accurate estimates of cancer risk for mutation carriers can be obtained. We therefore undertook to determine risks of breast and ovarian cancer for BRCA1 and BRCA2 mutation carriers ascertained irrespective of personal or family history of cancer. Families harboring mutations in BRCA1 or BRCA2 were ascertained by identifying mutation carriers among healthy AJ males recruited from health screening centers and outpatient clinics. Female relatives of the carriers were then enrolled and genotyped. Among the female relatives with BRCA1 or BRCA2 mutations, cumulative risk of developing either breast or ovarian cancer by age 60 and 80, respectively, were 0.60 (± 0.07) and 0.83 (± 0.07) for BRCA1 carriers and 0.33 (± 0.09) and 0.76 (± 0.13) for BRCA2 carriers. Risks were higher in recent vs. earlier birth cohorts (P = 0.006). High cancer risks in BRCA1 or BRCA2 mutation carriers identified through healthy males provide an evidence base for initiating a general screening program in the AJ population. General screening would identify many carriers who are not evaluated by genetic testing based on family history criteria. Such a program could serve as a model to investigate implementation and outcomes of population screening for genetic predisposition to cancer in other populations. genomics I nherited mutations in BRCA1 and BRCA2 predispose to high risks of breast and ovarian cancer. Among female mutation carriers, presymptomatic surgical measures significantly reduce morbidity and mortality (1, 2). In particular, risk-reducing salpingo-oophorectomy (i.e., the removal of ovaries and fallopian tubes from a woman without ovarian cancer) reduces risk both of breast cancer and of ovarian cancer, as well as overall mortality (1). However, for many mutation carriers identified following their first cancer diagnosis, genetic testing was not previously indicated because family history did not suggest inherited cancer predisposition (3)(4)(5)6). From a prevention perspective, it is a missed opportunity to identify a woman as a BRCA1 or BRCA2 mutation carrier only after she develops cancer.Among Ashkenazi (European) Jews (AJ), three mutations, BRCA1 185delAG, BRCA1 5382insC, and BRCA2 6174delT, account for the great majority of inherited cancer risk due to BRCA1 and BRCA2 (7). In the AJ population, 2.5% of persons carry one of these three mutations (8), and the mutations account for 11% of breast cancer (3) and 40% of ovarian cancer (9, 10). These observations suggest that genetic testing in the AJ population for these mutations fulfills WHO criteria for population screening (11, 12): The disease is an important public health burden to the target popu...
RMSSD, but not SDNN, seem a reliable parameter for assessing HRV from ultra-short (1 minute or 10 seconds) resting electrocardiographic recordings. Power spectral analysis and evaluation of other HRV parameters require longer recording periods. Further research is required to evaluate the importance of ultra-short RMSSD for cardiovascular risk stratification.
Streamlined BRCA screening results in high uptake, very high satisfaction, and no excess psychosocial harm. Proactive recruitment captured older women less selected for FH. Further research is necessary to target younger women and assess other populations.Genet Med advance online publication 08 December 2016.
Introduction: Colonic diverticulosis is a common condition with obscure pathogenesis. Obesity, hyperlipidemia and hypertension have been demonstrated to increase the risk of complicated diverticular disease, but the impact of metabolic risk factors on the prevalence of uncomplicated diverticulosis has not been clearly determined. Aims: The aim of the study was to examine the impact of obesity and metabolic syndrome on the prevalence of colonic diverticulosis. Methods: This retrospective case-control study included patients aged 40–85 years who were followed up by the Institute of Medical Screening in Israel and underwent colonoscopy in 2006–2011 for indication of colorectal cancer screening. Patients with diverticulosis as detected by colonoscopy were compared to patients without diverticulosis. The comparison parameters included medical history, biometric parameters, biochemical and lipid profile. Results: The study included 3,175 patients. Diverticulosis was diagnosed in 17.4% of the cohort. On univariate analysis, age, male gender, BMI (continuous variable), obesity, systolic blood pressure, low-density lipoprotein cholesterol level, history of hypertension, ischemic heart disease, hypothyroidism, and absence of diabetes mellitus were associated with an increased risk of colonic diverticulosis. On multivariate analysis, advanced age, male gender, obesity (BMI >30), history of hypothyroidism and absence of diabetes mellitus were associated with an increased risk of diverticulosis. Prevalence of colonic polyps was similar in patients with and without diverticulosis. Conclusion: Colonic diverticulosis was associated with age, male gender, obesity and hypothyroidism. Diabetes mellitus was associated with a decreased risk of colonic diverticulosis.
