Acute Kidney Injury in Pregnancies Complicated by Late-Onset Preeclampsia with Severe Features.

OBJECTIVE: Acute kidney injury (AKI)-complicating pregnancy is used as a marker of severe maternal morbidity (SMM) and frequently associated with obstetric hypertensive disorders. We examined AKI in pregnancies complicated by late-onset preeclampsia with severe features (SPE) using the Kidney Disease: Improving Global Outcomes (KDIGO) criteria. We compared outcomes of pregnancies with and without AKI and stratified by stage of disease. We further differentiated renal dysfunction at the time of admission and compared outcomes to those who developed AKI after admission. STUDY DESIGN: This was a retrospective cohort study of women with care established before 20 weeks and diagnosed with preeclampsia with severe features with delivery at ≥34 weeks. Women with chronic hypertension or suspected underlying renal dysfunction were excluded. KDIGO criteria were applied to stratify staging of renal disease. Demographics and perinatal outcomes were compared using Chi-square analysis and Wilcoxon's rank-sum test with p < 0.05 considered significant. RESULTS: From January 2015 through December 2019, a total of 3,515 women meeting study criteria were delivered. Of these, 517 (15%) women met KDIGO criteria for AKI at delivery with 248 (48%) having AKI at the time of admission and the remaining 269 (52%) after admission. Stratified by severity, 412 (80%) had stage 1 disease, 89 (17%) had stage II, and 16 (3%) had stage III. Women with AKI had higher rates of cesarean delivery (risk ratio [RR] = 1.3; 95% confidence interval [CI]: 1.17-1.44), postpartum hemorrhage (RR = 1.46; 95% CI: 1.29-1.66), and longer lengths of stay. Other associated outcomes included NICU admission (RR = 1.72; 95% CI: 1.19-2.48), 5-minute Apgar score ≤ 3 (RR = 5.11; 95% CI: 1.98-13.18), and infant length of stay. CONCLUSION: Of women with late preterm SPE, 15% were found to have AKI by KDIGO criteria. The majority (80%) of AKI was stage I disease, and approximately half of the cases were present by the time of admission. KEY POINTS: · AKI was found in 15% of our cohort with 80% stage I disease.. · Half of the cases of AKI were present on admission.. · Few adverse perinatal outcomes are associated with AKI..

Improving access to perinatal mental health services: the value of on-site resources.

BACKGROUND: Perinatal mood disorders have both short- and long-term negative consequences for mothers and their babies. National organizations recommend universal screening for postpartum depression. Little is known, however, about screening and referral among women living in underserved areas with limited access to care. OBJECTIVE: The objective of this report was to evaluate the utilization of mental health services in an urban, inner-city hospital following the implementation of colocated counseling services across 10 county-sponsored clinics that serve a medically underserved population. We further explored antecedents of a positive postpartum depression screen, factors associated with successful referral, and the rate of perinatal mood disorder diagnoses following universal screening. We hypothesized that integrated mental health services would improve referral rates following positive postpartum depression screening compared with historically separated services. STUDY DESIGN: This was a retrospective cohort study of women undergoing universal postpartum depression screening with deliveries from January 2017 to December 2019 who were compared with a historic cohort from the same population from June 2008 to March 2010. The Edinburgh Postnatal Depression Scale was used to evaluate women at their postpartum visit, and a mental health service referral was offered to women with a score of ≥13. The primary outcome was a comparison of completed referrals between cohorts with and without colocated mental health services following a positive postpartum depression screen. Statistical analysis included chi-square tests with a P value of <.05 being considered significant and adjusted multivariate analyses for perinatal outcomes associated with a positive postpartum screen. RESULTS: Between January 2017 to December 2019, 25,425 women completed a postpartum depression screen with 978 (4%) of those recording a positive screen. After implementation of colocated mental health counselors, completed perinatal mental health referrals significantly increased when compared with the historic cohort without colocated services (57%; 560 of 978 vs 22%; 238 of 1106; P<.001). Adverse neonatal outcomes, such as stillbirth (adjusted risk ratio, 9.5; 95% confidence interval, 6.35-14.26) and neonatal demise (adjusted risk ratio, 14.3; 95% confidence interval, 6.67-30.46), were most strongly associated with a positive depression screen. There were 122 (21%) women with a positive screen who were diagnosed with a depressive disorder in the peripartum period. There were no specific features associated with those who did or did not complete referral. One-fifth of women were referred for psychiatric evaluation following an initial evaluation, and the referral rate was associated with higher scores on the depression screen (P<.001). CONCLUSION: Utilization of mental health services following a positive depression screen more than doubled following the implementation of colocated services.

Timing of Emergency Postpartum Hospital Visits in the Fourth Trimester.

OBJECTIVE: The concept of the "fourth trimester" emphasizes the importance of individualized postpartum follow-up. Women seek care for urgent issues during this critical time period. Our objective was to evaluate trends in presenting complaints and admissions in an emergency setting over the first 42 days following delivery. STUDY DESIGN: Postpartum hospital encounters within 42 days of delivery at our institution from 2015 to 2019 were studied. Demographic information, delivery route, and emergent hospital encounter details were obtained from the electronic medical record. The postpartum encounters were analyzed by week of presentation. Statistical analysis included Student's t-test and Mantel-Haenszel test with p <0.05 considered significant. RESULTS: Of the 8,589 deliveries, 491 (5.7%) were complicated by an emergent hospital presentation within 42 days of delivery resulting in 576 hospital encounters. 35.9% of these visits occurred in the first week and 75.5% occurred within the first 3 weeks. Women presenting to the hospital were more commonly African American, higher body mass index, and delivered via cesarean. The most common chief complaints were fever, headache, abdominal pain, vaginal bleeding, hypertension, and wound concerns with temporal trends noted. 72% of admissions occur within 14 days of delivery and drop dramatically thereafter (p = 0.001). The most common diagnoses were hypertension/preeclampsia with severe features, vaginal bleeding/delayed postpartum hemorrhage, and wound infection. CONCLUSION: We observed important trends in presenting complaints and admission diagnoses of emergency postpartum visits in the first 42 days. The majority of hospital visits and admissions occur within the first 2 weeks postpartum. Understanding maternal conditions and reasons for accessing care through an emergency setting allows for tailoring of routine postpartum follow-up. KEY POINTS: · Women presenting in the postpartum period most commonly seek care within 3 weeks of delivery.. · Postpartum presentations requiring admission most frequently occur within 2 weeks of delivery.. · The most common diagnoses on presentation were hypentension, vaginal bleeding, and wound infections..

A Gap in Care? Postpartum Women Presenting to the Emergency Room and Getting Readmitted.

OBJECTIVE: Emergent postpartum hospital encounters in the first 42 days after birth are estimated to complicate 5 to 12% of births. Approximately 2% of these visits result in admission. Data on emergent visits and admissions are critically needed to address the current maternal morbidity crisis. Our objective is to characterize trends in emergent postpartum hospital encounters and readmissions through chief complaints and admission diagnoses over a 4.5-year period. STUDY DESIGN: All postpartum hospital encounters within 42 days of delivery at our institution from 2015 to 2019 were included. We reviewed demographic information, antepartum, intrapartum, and postpartum care and postpartum hospital encounters. Trends in hospital presentation and admission over the study period were analyzed. Comparisons between women who were admitted to those managed outpatient were performed. Statistical analysis included Chi-square, student's t-test, and Mantel-Haenszel test for trend and ANOVA, as appropriate. A p-value <0.05 considered significant. RESULTS: Among 8,589 deliveries, 491 (5.7%) presented emergently to the hospital within 42 days of delivery, resulting in 576 hospital encounters. From 2015 to 2019, annual rates of presentation were stable, ranging from 5.0 to 6.4% (p = 0.09). Of the 576 hospital encounters, 224 (38.9%) resulted in an admission with increasing rates from 2.0% in 2015 to 3.4% in 2019 (p = 0.005). Primiparous women with higher body mass index, cesarean delivery, and blood loss ≥1, 000 mL during delivery were significantly more likely to be admitted to the hospital. Women with psychiatric illnesses increasingly utilized the emergency room in the postpartum period (6.7-17.2%, p = 0.03). The most common presenting complaints were fever, abdominal pain, headache, vaginal bleeding, wound concerns, and high blood pressure. Admitting diagnoses were predominantly hypertensive disorder (22.9%), wound complications (12.8%), endometritis (9.6%), headache (6.9%), and delayed postpartum hemorrhage (5.6%). CONCLUSION: The average proportion of women presenting for an emergent hospital encounter in the immediate 42-day postpartum period is 5.7%. Nearly 40% of emergent hospital encounters resulted in admission and the rate increased from to 2.0 to 3.4% over the study period. The most common reasons for presentation were fever, abdominal pain, headache, vaginal bleeding, wound concerns, and hypertension. Hypertension, wound complications, and endometritis accounted for the top three admission diagnoses.

CSF concentrations of 5-methyltetrahydrofolate in a cohort of young children with autism.

OBJECTIVE: To examine the association between cerebral folate deficiency and autism, this study examined CSF 5-methyltetrahydrofolate (5-MTHF) concentrations in a group of young children with autism, investigated the natural variation in CSF 5-MTHF over time, and assessed the relationship between CSF 5-MTHF and symptoms. METHODS: CSF was collected from 67 children with a diagnosis of DSM-IV-TR autistic disorder (age, mean ± SD 43 ± 11 months), with a second CSF sample obtained 1-3 years later on 31 of these subjects (time to follow-up, 30 ± 8 months). RESULTS: At time 1, 7% (5/67) of participants had 5-MTHF <40 nmol/L. At follow-up, 23% (7/31) of participants had 5-MTHF <40 nmol/L (only one of whom had been low at time 1). A moderate correlation with a very wide confidence interval (CI) was observed between time 1 and time 2 CSF 5-MTHF measurements (Pearson r[p] = 0.38 [0.04]; 95% CI 0.02-0.64). Neither the CSF 5-MTHF levels nor changes over time correlated with the clinical features of autism. CONCLUSIONS: CSF 5-MTHF levels vary significantly over time in an unpredictable fashion and do not show a significant relationship to typical clinical features of autism. Reduced CSF 5-MTHF levels are a nonspecific finding in autism. Our data do not support the use of lumbar puncture for assessment of CSF 5-MTHF in autism.
