Outcomes of infants with pulmonary atresia with intact ventricular septum listed for heart transplantation: A multi-institutional study.

BACKGROUND: Management of infants with pulmonary atresia/intact ventricular septum (PA/IVS) is variable. Because of higher mortality in more severe forms, heart transplant (HT) is an acceptable approach, but waitlist and post-transplant outcomes are unclear. This study compared outcomes of infants with PA/IVS vs. other single ventricle (SV) anatomies listed for HT. METHODS: Data from the Pediatric Heart Transplant Society (1993-2018) were analyzed for survival and risk factors for mortality. RESULTS: Of 1617 SV infants, 300 had PA/IVS (19%) and 1317 had other SV (81%). Overall, 1-, 5-, and 10-year survival was higher among PA/IVS (74%, 65%, 61%) versus other SV infants (62%, 54%, 50%, p = .004). While waitlist mortality was similar between groups (p = .09), PA/IVS was an independent predictor of improved waitlist survival (HR 0.68, p = .03), and PA/IVS infants had higher incidence of waitlist removal (8% vs. 5.5%, p = .03), most commonly for being "too well." Post-transplant survival was superior among PA/IVS versus other SV infants (1- and 5-year survival 93% and 81% vs. 80% and 71%, p < .0001). Risk factors for PA/IVS waitlist mortality (2008-2018) included extracorporeal membrane oxygenation and mechanical ventilation. Prior aortopulmonary (AP) shunt among PA/IVS infants was associated with improved waitlist survival. CONCLUSIONS: Overall survival among PA/IVS infants listed for HT exceeds that of other SV infants with PA/IVS identified as an independent predictor of improved waitlist and post-transplant survival. Prior AP shunt among listed PA/IVS infants was associated with improved waitlist outcomes, though, which may reflect a listing selection bias.

Understanding disorders of sexual development.

Studies estimate that the incidence of genital anomalies could be as high as 1 in 300 births. While it is rare for an infant to present with truly ambiguous genitalia, it is plausible that the pediatric nurse will encounter a patient with disorders of sexual development in his or her career. Cases of disorders of sexual development are challenging due to complexities of diagnosis, gender assignment, uncertain outcomes, treatment options, and psychosocial stressors. This article discusses the evaluation and management of children with disorders of sexual development and the nurse's role as child advocate and family educator.

Parenting attitudes and infant spanking: the influence of childhood experiences.

OBJECTIVES: To assess associations among maternal childhood experiences and subsequent parenting attitudes and use of infant spanking (IS), and determine if attitudes mediate the association between physical abuse exposure and IS. METHODS: We performed a prospective study of women who received prenatal care at community health centers in Philadelphia, Pennsylvania. Sociodemographic characteristics, adverse childhood experiences (ACEs), attitudes toward corporal punishment (CP), and IS use were assessed via face-to-face interviews, conducted at the first prenatal care visit, 3 months postpartum, and 11 months postpartum. Bivariate and multiple logistic regression analyses were conducted. RESULTS: The sample consisted of 1265 mostly black, low-income women. Nineteen percent of the participants valued CP as a means of discipline, and 14% reported IS use. Mothers exposed to childhood physical abuse and verbal hostility were more likely to report IS use than those not exposed (16% vs 10%, P = .002; 17% vs 12%, P = .02, respectively). In the adjusted analyses, maternal exposure to physical abuse, other ACEs, and valuing CP were independently associated with IS use. Attitudes that value CP did not mediate these associations. CONCLUSIONS: Mothers who had childhood experiences of violence were more likely to use IS than mothers without such experiences. Intergenerational transmission of CP was evident. Mothers who had experienced physical abuse as a child, when compared to those who had not, were 1.5 times more likely to use IS. Child discipline attitudes and maternal childhood experiences should be discussed early in parenting in order to prevent IS use, particularly among at-risk mothers.
