Background: Ductal-dependent cyanotic newborns require a secure source of pulmonary blood flow. There has been a recent migration to selective ductal (patent ductus arteriosus [PDA]) stenting for some of these children. Universal (nonselective) ductal stenting for all infants with ductal-dependent pulmonary blood flow is controversial. We examine outcomes from a single center with this practice change. Methods: We compare outcomes of all ductal-dependent pulmonary blood flow infants (2013–2020 [January–June]) in the following treatment eras: Era 1 (selective PDA stenting; 2013–2017) or Era 2 (universal PDA stenting; 2018–2020 [January–June]). Results: Eighty-eight patients (Blalock-Taussig shunt, n=41; PDA stent, n=47) met inclusion criteria. In Era 1, most received Blalock-Taussig shunt (62% [41/66]). In Era 2, all received PDA stents (100% [22/22]). There were more females in Era 2, but otherwise no demographic differences between eras. There were no differences in mortality, treatment failures, complications, or reinterventions between eras. Postprocedure length of stay was shorter in Era 2 (8 versus 22 days, P =0.02). There were less surgical revisions for PDA stent patients (2% versus 20%, P =0.02). Postprocedure recovery surrogate end points favored Era 2 and PDA stenting. Additional analysis revealed PDA stent (compared with Blalock-Taussig shunt) patients had shorter post-procedure (10 versus 29 days, P≤ 0.001) length of stay and more symmetrical branch pulmonary arteries (0.9 versus 0.7, P =0.001) at subsequent surgery. Conclusions: PDA stenting for almost all ductal dependent cyanotic newborns can be safe and effective and may have lower morbidity than selective PDA stenting.

Background Parkinson disease (PD) psychosis (PDP) is a disabling non-motor symptom. Pharmacologic treatment is limited to pimavanserin, quetiapine, and clozapine, which do not worsen parkinsonism. A Food and Drug Administration black box warning exists for antipsychotics, suggesting increased mortality in elderly patients with dementia. However, the reasons for higher mortality are unknown. Aim Expanding on prior work exploring mortality in treated PDP patients, we conducted a retrospective comparison to understand the links between treatment regimen, clinical characteristics, and negative outcomes. Methods Electronic medical record data extraction included clinically diagnosed PD patients between 4/29/16-4/29/19 and excluded patients with primary psychiatric diagnoses or atypical parkinsonism. Mortality and clinical characteristics during the study period were compared between untreated patients and those receiving pimavanserin, quetiapine, or both agents (combination). Mortality analyses were adjusted for age, sex, levodopa equivalent daily dose (LEDD), and dementia. Results The pimavanserin group (n = 34) had lower mortality than the untreated group (n = 66) (odds ratio = 0.171, 95% confidence interval: 0.025–0.676, p = 0.026). The untreated group had similar mortality compared to the quetiapine (n = 147) and combination (n = 68) groups. All treated groups had a higher LEDD compared to the untreated group, but no other differences in demographics, hospitalizations, medical comorbidities, medications, or laboratory values were found between the untreated and treated groups. Conclusions PDP patients receiving pimavanserin had lower mortality than untreated patients. We found no other clear differences in clinical characteristics to explain the mortality risk. Prospective randomized trials are needed to definitively identify the optimal PDP treatment regimen and associated risks.

Objective The study compares the short-term outcomes of late preterm infants (LPI) at an academic center in San Diego, California after a change in protocol that eliminated a previously mandatory 12-hour neonatal intensive care unit (NICU) observation period after birth. Study Design This is a retrospective observational study examining all LPI born with gestational age 35 to 366/7 weeks between October 1, 2016 and October 31, 2017. A total of 189 infants were included in the review. Short-term outcomes were analyzed before and after the protocol change. Results Transfers to the NICU from family-centered care (FCC) were considerably higher (23.2%) following the protocol change, compared to before (8.2%). More infants were transferred to the NICU for failed car seat tests postprotocol compared to preprotocol. Length of stay before the protocol change was 5.13 days compared to 4.80 days after. Conclusion LPI are vulnerable to morbidities after delivery and through discharge. We found an increase in failed car seat tests in LPI cared for in FCC after elimination of a mandatory NICU observation after birth. The transitions of care from delivery to discharge are key checkpoints in minimizing complications.
