RESUMEN
Background: Peripartum cardiomyopathy (PPCM) is a common cause of heart failure (HF) in the peripartum. Some medications are considered safe while breastfeeding. However, sacubitril/valsartan (Entresto), while efficacious, is not recommended in breastfeeding women due to concerns about adverse infant development, and no published data suggest otherwise. Objectives: This study aimed to assess the transfer of sacubitril/valsartan into human milk and evaluate the infant's risk of drug exposure. Methods: The InfantRisk Human Milk Biorepository released samples and corresponding health information from five breastfeeding maternal-infant dyads exposed to sacubitril/valsartan. Sacubitril, valsartan, and LBQ657 (sacubitril active metabolite) concentrations were determined using liquid chromatography-mass spectrometry (LC/MS/MS) from timed samples 0, 1, 2, 4, 6, 8, 10, and 12 h following medication administration at steady state conditions. Results: Valsartan levels were below the detection limit of 0.19 ng/mL in all milk samples. Sacubitril was measurable in all milk samples of the five participants, peaking 1 h after drug administration at a mean concentration of 1.52 ng/mL for a total infant dose of 0.00049 mg/kg/12 h and a relative infant dose (RID) calculated at 0.01%. The maximum concentration of its active metabolite LBQ657 in the milk samples was observed 4 h after medication administration and declined over the remaining 12-h dosing interval, for an average concentration of 9.5 ng/mL. The total infant dose was 0.00071 mg/kg/12 h, and the RID was 0.22%. Two mothers reported continuing to breastfeed while taking sacubitril/valsartan; both mothers stated observing no negative effects in their breastfed infants. Conclusion: The transfer of sacubitril/valsartan into human milk is minimal. These concentrations are unlikely to pose a significant risk to breastfeeding infants, with a combined calculated RID of <0.25%, which is far lower than the industry safety standards (RID <10%).

Neurologic emergencies in pregnancy require prompt evaluation and early, focused intervention to improve neurologic outcomes for the affected person and to avoid further injury. Neurologic events in pregnancy, although rare, present a time of extreme risk of permanent injury for the person who is pregnant. Therefore, obstetric clinicians should be well versed in the risk factors for potential neurologic events and understand the symptoms and events that should prompt evaluation for a neurologic event. In addition, they should support other specialties in aggressive and early neurologic care for the patient to improve outcomes while assessing fetal well-being and care optimization for the dyad. Obstetric clinicians can uniquely provide knowledge of changes in pregnancy physiology that can increase the risk of neurologic events, as well as change the treatment of these events. For all patients with neurologic events, "time is brain." Therefore, it is important to be aware of changes in common presenting pregnancy concerns that should prompt evaluation for other pathogeneses. Finally, pregnancy care teams should be prepared to begin the initial stabilization and management of acute neurologic emergencies, including seizure, stroke, and meningitis, while seeking aid from other medical and neurologic specialists who can support their care and interventions. Early and aggressive interventions for individuals with neurologic events during pregnancy and postpartum are critical to the overall well-being of the dyad.

BACKGROUND: Septic abortion with multisystem involvement is associated with significant morbidity and mortality. Access to care and legalization of abortion have greatly diminished the incidence of serious sequelae worldwide. Two complications, infective endocarditis and septic arthritis, are rarely encountered in contemporary practice. CASE: A 30-year-old woman developed infective endocarditis, septic arthritis, and reactive arthritis concurrently one week after undergoing dilation and curettage for an incomplete abortion with perioperative administration of doxycycline. She required systemic antibiotics, drainage and debridement of her right ankle, and a robotic-assisted mitral valve replacement due to septic vegetation. CONCLUSION: Septic abortion with life-threatening systemic complications is rarely encountered in modern practice. Prompt surgical uterine evacuation and broad-spectrum antibiotics are indicated to prevent systemic complications. Multispecialty consultation is usually required when endocarditis, arthritis, and other systemic complications are encountered.
