Reactions to the first clinical recommendations for the return of incidental findings (IFs) from genomic sequencing published by the American College of Medical Genetics and Genomics (ACMG) were polarized and resolute. Exploring the three main points of controversy: mandatory testing, testing children for adult conditions, and selection of conditions to be reported on, illuminates concerns for and conservation of bioethical principles—specifically, autonomy and non-directiveness. With the historical context of genetic testing in mind, this article studies the potential application of the ACMG recommendations to embryonic testing in the form of preimplantation genetic diagnosis. Theoretical extension of the current recommendations assists in the identification of bioethical dilemmas and possible societal impacts. The recommendations make a statement on the importance of diagnosis and intervention for specific genetic conditions, setting a precedent for disease classification and patient autonomy. In the extreme, the clinical application of such recommendations prenatally may result in discarded embryos, and less societal tolerance of specific conditions. Skilled professionals, such as genetic counselors, researchers, and lawmakers must work together to maintain patient autonomy, providing care in the best interest of each patient. 相似文献

Objective: This study retrospectively examined the daily-level associations between youth alcohol use and dating abuse (DA) victimization and perpetration for a 6-month period. Method: Timeline Followback (TLFB) interview data were collected from 397 urban emergency department patients, ages 17 to 21 years. Patients were eligible if they reported past month alcohol use and past year dating. Generalized estimating equation (GEE) analyses estimated the likelihood of DA on a given day as a function of alcohol use or heavy use (≥4 drinks per day for women, ≥5 drinks per day for men), as compared with nonuse. Results: Approximately 52% of men and 61% of women participants reported experiencing DA victimization ≥1 times during the past 6 months, and 45% of men and 55% of women reported perpetrating DA ≥1 times. For both men and women, DA perpetration was more likely on a drinking day as opposed to a nondrinking day (ORs = 1.70 and ORs = 1.69, respectively). DA victimization was also more likely on a drinking day as opposed to a nondrinking day for both men and women (ORs = 1.23 and ORs = 1.34, respectively). DA perpetration and DA victimization were both more likely on heavy drinking days as opposed to nondrinking days (2.04 and 2.03 for men's and women's perpetration, respectively, and 1.41 and 1.43 for men's and women's victimization, respectively). Conclusions: This study found that alcohol use was associated with increased risk for same day DA perpetration and victimization, for both male and female youth. We conclude that for youth who use alcohol, alcohol use is a potential risk factor for DA victimization and perpetration. 相似文献
