Inherited cardiac arrhythmias such as long QT syndrome and Brugada syndrome, present clinical as well as ethical, legal, and social challenges. Many individuals who carry a deleterious mutation are largely asymptomatic and therefore may not be diagnosed until after the occurrence of a personal or family member’s cardiac event. The familial nature of inherited genetic information raises numerous ethical, legal, and social issues regarding the sharing of genetic information, particularly when an individual found to carry a deleterious mutation refuses to disclose his or her results to at-risk family members who could benefit from life-saving treatments. This qualitative study sought to understand the experiences with genetic testing for individuals (n= 50) with a personal or family history of cardiac events or sudden death. Unstructured in-person focus groups or interviews were conducted for each participant in the study. The recordings of these interviews were transcribed verbatim and subsequently analyzed and coded. Participants’ comments regarding sharing of genetic information centered around four main themes: (1) motivation to disclose; (2) extent of disclosure; (3) effect of disclosure on family dynamics; and (4) reasons for not sharing genetic information. The majority of individuals believed that affected individuals are obligated to disclose genetic information to family members. In the era of personalized medicine, the disclosure of genetic information provides individuals the opportunities to learn about the genetics, disease characteristics, and treatment options in order to reduce morbidity and mortality in themselves and their family members. Further research is necessary to identify and explore the barriers to sharing genetic information with at-risk family members.

BACKGROUND AND OBJECTIVES: Opiate use in neonates can affect clinical outcomes after surgery and may alter future neurodevelopment. We implemented a multimodal opioid reduction strategy in our NICU for infants undergoing nonemergent gastrointestinal surgery. METHODS: After multiple stakeholder’s meetings, our opioid reduction intervention included giving neonates postoperative standing intravenous acetaminophen every 6 hours for 48 hours, a standardized postsurgical sign-out with the NICU team in which pain control was directly addressed, and a series of postsurgical pain education seminars with NICU providers. To assess the impact of our quality improvement project, we used process control charts to investigate trends in postoperative opioid use in our preintervention (January 2012 to April 2016) and postintervention (May 2016 to September 2019) cohorts. RESULTS: A total of 77 infants were included in the study (40 in the preintervention cohort and 37 in the postintervention cohort). Patient characteristics were equivalent. The intervention significantly reduced the trend in postoperative morphine equivalents (median: 7.96 mg/kg in preintervention cohort versus 0.095 mg/kg in postintervention cohort; P < .0001). The Neonatal Pain, Agitation, and Sedation Scale pain scores and safety profiles were equivalent in both groups. The intervention was also associated with a 24-hour reduction in postoperative ventilation time (P < .048) and a 7-day reduction in the use of total parenteral nutrition (P < .017). CONCLUSIONS: Standing intravenous acetaminophen coupled with provider education can successfully reduce opioid use in postsurgical neonates. Given the concern for opioid exposure in neonatal neurodevelopment as well as clinical benefits of reduced opioids, similar strategies for opioid reduction may prove useful at other institutions.

BackgroundA vaccine containing 6 melanoma-associated peptides to stimulate helper T cells (6MHP) is safe, immunogenic, and clinically active. A phase I/II trial was designed to evaluate safety and immunogenicity of 6MHP vaccines plus programmed death 1 (PD-1) blockade.Participants and methodsParticipants with advanced melanoma received 6MHP vaccines in an incomplete Freund’s adjuvant (6 vaccines over 12 weeks). Pembrolizumab was administered intravenously every 3 weeks. Tumor biopsies at baseline and day 22 were analyzed by multiplex immunohistochemistry. Primary end points were safety (Common Terminology Criteria for Adverse Events V.4.03) and immunogenicity (ex vivo interferon-γ ELISpot assay). Additional end points included changes in the tumor microenvironment (TME) and clinical outcomes.ResultsTwenty-two eligible participants were treated: 6 naïve to PD-1 antibody (Ab) and 16 PD-1 Ab-experienced. Median follow-up was 24.4 months. Most common treatment-related adverse events (any grade) included injection site reactions, fatigue, anemia, lymphopenia, fever, elevated aspartate aminotransferase, pruritus, and rash. Treatment-related dose-limiting toxicities were observed in 3 (14%) participants, which did not cross the study safety bound. A high durable T cell response (Rsp) to 6MHP was detected in only one participant, but twofold T cell Rsps to 6MHP were detected in 7/22 (32%; 90% CI (16% to 52%)) by week 13. Objective clinical responses were observed in 23% (1 complete response, 4 partial responses), including 4/6 PD-1 Ab-naïve (67%) and 1/16 PD-1 Ab-experienced (6%). Overall survival (OS) was longer for PD-1 Ab-naïve than Ab-experienced participants (HR 6.3 (90% CI (2.1 to 28.7)). In landmark analyses at 13 weeks, OS was also longer for those with T cell Rsps (HR 6.5 (90% CI (2.1 to 29.2)) and for those with objective clinical responses. TME evaluation revealed increased densities of CD8+ T cells, CD20+ B cells, and Tbet+ cells by day 22.ConclusionsTreatment with the 6MHP vaccine plus pembrolizumab was safe, increased intratumoral lymphocytes, and induced T cell Rsps associated with prolonged OS. The low T cell Rsp rate in PD-1 Ab-experienced participants corroborates prior murine studies that caution against delaying cancer vaccines until after PD-1 blockade. The promising objective response rate and OS in PD-1 Ab-naïve participants support consideration of a larger study in that setting.
