OBJECTIVES: Evaluate the association between maternal social factors and maternal time spent in the NICU for very preterm infants admitted to 4 level III and IV NICUs.
METHODS:In this prospective observational cohort study, we enrolled mother-infant dyads whose infants were born <32 weeks' gestation. Enrollment occurred after 2 weeks of NICU exposure, when maternal social factors and demographic information was collected. Maternal time spent in the NICU was abstracted from the electronic medical record and was dichotomized into 0 to 6 days and $6 days per week. Demographic differences between the 2 groups were compared by using v 2 tests. Logistic regression was used to assess the independent association between maternal social factors and the average number of days per week spent in the NICU.
We report a case of a 1-month-old infant with spontaneous thymic hemorrhage secondary to severe vitamin K deficiency. He was brought to medical attention due to scrotal bruising and during evaluation was noted to be tachypneic and hypoxemic. Chest X-ray revealed an enlarged cardiothymic silhouette, and a follow-up echocardiogram revealed a mass in the anterior mediastinum. Routine laboratory work-up revealed severe coagulopathy. Further questioning revealed the patient had not received prophylactic vitamin K at birth. The coagulopathy resolved with administration of vitamin K, and a biopsy confirmed the anterior mediastinal mass was due to spontaneous thymic hemorrhage.
Serotonergic medications are used for the prevention and treatment of depression during pregnancy. Selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors (SNRIs) can cause poor neonatal adaptation, which has been attributed to withdrawal versus toxicity. Bupropion, a norepinephrine-dopamine reuptake inhibitor, is often used as an adjunctive agent to selective serotonin reuptake inhibitors or SNRIs for refractory depression. Quetiapine, an atypical antipsychotic, may also be used in more complex cases. When combined with serotonergic drugs, bupropion and quetiapine are associated with increased risk of serotonin syndrome in adults. We describe a neonate exposed to venlafaxine (an SNRI), bupropion, and quetiapine in utero who presented nearly immediately after birth with encephalopathy and abnormal movements. The severity and rapidity of symptoms may be attributable to potentiation of venlafaxine’s serotonergic effects by bupropion and quetiapine. Neonatal providers should be aware of maternal medications and prepare for possible adverse effects, particularly from common psychotropic exposures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
