Legal and ethical issues in cancer genetics nursing

OBJECTIVES: This article will set forth major interests at stake for patients considering predictive genetic testing, some legal bases for protecting patients, and general ethical principles that can guide cancer genetic nurses in their practice. DATA SOURCES: Review of health, ethical, and legal literature CONCLUSION: There are many potential interests at stake for patients considering genetic testing for susceptibility to cancer and a number of legal protections for patients against genetic discrimination. Nurses and physicians who offer genetic testing should be aware of applicable laws in their states, and remain cognizant of evolving ethical principles that can guide the practice IMPLICATIONS FOR NURSING PRACTICE: Ethical and legal questions surrounding genetic testing linger--particularly for nurses and physicians whose primary concern is the best interests of the patient.     

Temporal Dynamics of the Intestinal Microbiome Following Short-Term Dietary Restriction

Short-term dietary restriction has been proposed as an intriguing pre-operative conditioning strategy designed to attenuate the surgical stress response and improve outcomes. However, it is unclear how this nutritional intervention influences the microbiome, which is known to modulate the systemic condition. Healthy individuals were recruited to participate in a four-day, 70% protein-restricted, 30% calorie-restricted diet, and stool samples were collected at baseline, after the restricted diet, and after resuming normal food intake. Taxonomy and functional pathway analysis was performed via shotgun metagenomic sequencing, prevalence filtering, and differential abundance analysis. High prevalence species were altered by the dietary intervention but quickly returned to baseline after restarting a regular diet. Composition and functional changes after the restricted diet included the decreased relative abundance of commensal bacteria and a catabolic phenotype. Notable species changes included Faecalibacterium prausnitzii and Roseburia intestinalis, which are major butyrate producers within the colon and are characteristically decreased in many disease states. The macronutrient components of the diet might have influenced these changes. We conclude that short-term dietary restriction modulates the ecology of the gut microbiome, with this modulation being characterized by a relative dysbiosis.     

An outbreak of Q fever associated with parturient cat exposure at an animal refuge and veterinary clinic in southeast Queensland

Objective: To determine the source of a Q fever outbreak in humans at an animal refuge and veterinary clinic in southeast Queensland from October to December 2016. Methods: Case interviews and a retrospective cohort study of animal refuge and veterinary clinic staff using a self‐administered questionnaire related to clinical history of Q fever, Q fever vaccination status and workplace activities during the exposure period. Results: Seven cases (six confirmed, one probable) were identified. Forty‐three questionnaires were completed (92% response rate). Workplace activities associated with the greatest risk of illness were the disposal of deceased cats or dogs (RR, 14.0; 95%CI, 1.9–104.1) and participating in euthanasia of cats or dogs (RR, 4.6; 95%CI, 1.3–16.9). Five feline birthing events occurred at the animal refuge from 25 September to 19 October 2016, each with subsequent euthanasia of the queen cat and litter. All cases had likely exposure to a specific queen cat and her litter that were euthanised the same day as the birthing event. Conclusions: A parturient cat was the most likely source of the outbreak. Implications for public health: Occupational groups and others with regular exposure to feline or canine parturient products should receive Q fever vaccine.     

Midwives and Liability: Results from the 2009 Nationwide Survey of Certified Nurse‐Midwives and Certified Midwives in the United States

Introduction: In partnership with the American College of Nurse‐Midwives (ACNM), the authors conducted a survey of ACNM members to examine the incidence of lawsuit involvement, the outcomes of the litigation in which they were involved, and coping mechanisms among midwives who had been involved in a lawsuit. Methods: In the spring of 2009, a nationwide Web‐based survey was completed by ACNM members. In addition to using chi‐square tests and nonparametric testing in data analysis, a logistic regression model was used to evaluate predictors of lawsuit involvement. Results: Among 1340 midwives responding to the survey, 32% had been named in a lawsuit at least once. The median number of years in practice when the event leading to lawsuit occurred was 6. The majority of midwifery lawsuits involved hospital births and were settled prior to going to court. Three variables were statistically significant for involvement with litigation: the midwife's age, the number of births attended, and the ACNM region of practice in the United States. Discussion: Lawsuits among midwives were significantly related to exposure to births over time. Practice patterns and job security were not greatly affected by the experience of a lawsuit. Future cyclic surveys are needed to track the frequency of litigation and the outcomes that lead to lawsuits and to better define the relationships between midwifery practice and medical malpractice litigation.
