Objective Maternal risk stratification systems are increasingly employed in predicting and preventing obstetric complications. These systems focus primarily on maternal morbidity, and few tools exist to stratify neonatal risk. We sought to determine if a maternal risk stratification score was associated with neonatal morbidity. Study Design Retrospective cohort study of patients with liveborn infants born at ≥24 weeks at four hospitals in one health system between January 1, 2020, and December 31, 2020. The Expanded Obstetric Comorbidity Score (EOCS) is used as the maternal risk score. The primary neonatal outcome was 5-minute Apgar <7. Logistic regression models determined associations between EOCS and neonatal morbidity. Secondary analyses were performed, including stratifying outcomes by gestational age and limiting analysis to "low-risk" term singletons. Model discrimination assessed using the area under the receiver operating characteristic curves (AUC) and calibration via calibration plots. Results A total of 14,497 maternal–neonatal pairs were included; 236 (1.6%) had 5-minute Apgar <7; EOCS was higher in 5-minute Apgar <7 group (median 41 vs. 11, p < 0.001). AUC for EOCS in predicting Apgar <7 was 0.72 (95% Confidence Interval (CI) 0.68, 0.75), demonstrating relatively good discrimination. Calibration plot revealed that those in the highest EOCS decile had higher risk of neonatal morbidity (7.6 vs. 1.7%, p < 0.001). When stratified by gestational age, discrimination weakened with advancing gestational age: AUC 0.70 for <28 weeks, 0.63 for 28 to 31 weeks, 0.64 for 32 to 36 weeks, and 0.61 for ≥37 weeks. When limited to term low-risk singletons, EOCS had lower discrimination for predicting neonatal morbidity and was not well calibrated. Conclusion A maternal morbidity risk stratification system does not perform well in most patients giving birth, at low risk for neonatal complications. The findings suggest that the association between EOCS and 5-minute Apgar <7 likely reflects a relationship with prematurity. This study cautions against intentional or unintentional extrapolation of maternal morbidity risk for neonatal risk, especially for term deliveries. Key Points EOCS had moderate discrimination for Apgar <7. Predictive performance declined when limited to low-risk term singletons. Relationship between EOCS and Apgar <7 was likely driven by prematurity. [ABSTRACT FROM AUTHOR]

Among diffuse large b-cell lymphoma (DLBCL) subtypes, primary testicular lymphoma (PTL) has one of the highest risks of central nervous system (CNS) relapse. The converse, primary CNS lymphoma (PCNSL) relapse outside the CNS is rare. Molecular analysis has illustrated a genetic similarity between PTL and PCNSL. Here we present a case of a 64-year-old man with testicular relapse of PCNSL 20 months after a complete response to high dose methotrexate-based chemotherapy. His tumor demonstrated a molecular profile similar to both PCNSL and PTL on next generation sequencing, and molecular analysis confirmed common clonal origin of his CNS and testicular lesions. We review prior cases of testicular relapse of PCNSL, which lacked molecular investigations, and discuss the implications of the genomic findings in our patient, including future treatment options.

Despite evidence to support the safety and efficacy of COVID-19 vaccination in pregnancy, and clear recommendations from professional organizations and the Centers for Disease Control and Prevention (CDC) for pregnant people to get vaccinated, COVID-19 vaccine hesitancy in pregnancy remains a significant public health problem. The emergence of the highly transmissible B.1.617.2 (Delta) variant among primarily unvaccinated people has exposed the cost of vaccine hesitancy. In this commentary, we explore factors contributing to COVID-19 vaccine hesitancy in pregnancy and potential solutions to overcome them. Key Points Low COVID-19 vaccination coverage in pregnant people is a major public health problem in the United States. COVID-19 vaccine hesitancy in pregnancy is multifactorial. The "4 Cs" framework may be useful in countering COVID-19 vaccine hesitancy. [ABSTRACT FROM AUTHOR]

Background: Adenovirus infection is usually mild in presentation. However during pregnancy, the course can be more severe. Case: A 21-year-old woman in her second pregnancy presented with abdominal pain, vomiting, and fevers at 34 weeks and 4 days of gestation. Her respiratory pathogen panel on nasopharyngeal secretions was positive for adenovirus. Electrolytes were notable for hypomagnesaemia and persistent hypokalemia (nadir of 2.6 mmol/L) despite repletion but otherwise unremarkable. During her course, she developed rhabdomyolysis. During routine fetal monitoring at 35 weeks and 6 days of gestation, prolonged fetal bradycardia was identified, and an emergency caesarean delivery was performed. The infant had no clinical or laboratory evidence of adenovirus infection. The patient had a protracted clinical course but recovered with supportive care. Conclusion: Adenovirus can present with severe complications in a pregnant woman including hypokalemia and rhabdomyolysis. The mainstay of treatment is supportive care and monitoring of electrolyte abnormalities and renal function. [ABSTRACT FROM AUTHOR]
