Perinatal Outcomes of Late Preterm Rupture of Membranes with or without Latency Antibiotics.

OBJECTIVE: This study aimed to examine whether the addition of latency antibiotics in late preterm rupture of membranes (ROM) decreases neonatal infection and increases latency. STUDY DESIGN: This retrospective two-center study was conducted at Holy Family Hospital (HFH) in Nazareth and Emek Medical Center (EMC) in Afula, on data collected between January 2017 and April 2023. HFH is the smaller institution. EMC and HFH implement similar policies regarding ROM at 340/7 to 366/7 weeks' gestation; the only difference is that a 10-day course of latency antibiotics is implemented at EMC. All women with ROM between 340/7 and 366/7 weeks' gestation who were admitted to one of the centers during the study period, and had a live fetus without major malformations, were included. The primary outcome was neonatal sepsis rate. Secondary outcomes included a composite of neonatal sepsis, mechanical ventilation ≥24 hours, and perinatal death. Additionally, gestational age at delivery and delivery mode were examined. RESULTS: Overall, 721 neonates were delivered during the study period: 534 at EMC (where latency antibiotics were administered) and 187 at HFH. The gestational age at ROM was similar (35.8 and 35.9 weeks, respectively, p = 0.14). Neonatal sepsis occurred in six (1.1%) neonates at EMC and one (0.5%) neonate at HFH (adjusted p = 0.71; OR: 1.69; 95% Confidence Interval [CI]: 0.11-27.14). The composite secondary outcome occurred in nine (1.7%) and three (1.6%) neonates at EMC and HFH, respectively (adjusted p = 0.71; OR: 0.73; 95% CI: 0.14-3.83). The gestational age at delivery was 36.1 and 36.2 weeks at EMC and HFH, respectively (mean difference: 5 h; adjusted p = 0.02). The cesarean delivery rate was 24.7% and 19.3% at EMC and HFH, respectively (adjusted p = 0.96). CONCLUSION: Latency antibiotics administered to women admitted with ROM between 340/7 and 366/7 weeks' gestation did not decrease the rate of neonatal sepsis. KEY POINTS: · Latency antibiotics in late preterm ROM does not decrease neonatal sepsis.. · Latency antibiotics in late preterm ROM does not prolong gestational age at delivery.. · Latency antibiotics in late preterm ROM does not affect the mode of delivery..

The Impact of Routine Evaluation of Gastric Residual Volumes on the Time to Achieve Full Enteral Feeding in Preterm Infants.

OBJECTIVE: To evaluate the time to full enteral feedings in preterm infants after a practice change from routine evaluation of gastric residual volume before each feeding to selective evaluation of gastric residual volume , and to evaluate the impact of this change on the incidence of necrotizing enterocolitis (NEC). STUDY DESIGN: Data were collected on all gavage-fed infants born at ≤34 weeks gestational age (GA) for 2 years before (n = 239) and 2 years after the change (n = 233). RESULTS: The median GA was 32.0 (IQR: 29.7-33.0) weeks before and 32.4 (30.4-33.4) weeks after the change (P = .02). Compared with historic controls, infants with selective evaluations of gastric residual volumes weaned from parenteral nutrition 1 day earlier (P < .001) and achieved full enteral feedings (150 cc/kg/day) 1 day earlier (P = .002). The time to full oral feedings and lengths of stay were similar. The rate of NEC (stage ≥ 2) was 1.7% in the selective gastric residual volume evaluation group compared with 3.3% in the historic control group (P = .4). Multiple regression analyses showed that the strongest predictor of time to full enteral feedings was GA. Routine evaluation of gastric residual volume and increasing time on noninvasive ventilation both prolonged the attainment of full enteral feedings. Findings were consistent in the subgroup with birth weights of <1500 g. Increased weight at discharge was most strongly associated with advancing postmenstrual, age but avoidance of routine evaluations of gastric residual volume also was a significant factor. CONCLUSIONS: Avoiding routine evaluation of gastric residual volume before every feeding was associated with earlier attainment of full enteral feedings without increasing risk for NEC.

Evaluation and Management of Newborns with Suspected Early-Onset Sepsis: Comparison of Two Approaches and Suggestion for Guidelines.

Objective Although its incidence is declining with the widespread use of intrapartum antibiotics, early-onset sepsis (EOS) continues to be associated with high morbidity and mortality. Maternal, infant, and peripartum risk factors, as well as infant's laboratory tests, have been used to try and identify asymptomatic newborns at risk. In this study, we reevaluate the management of newborns at risk for EOS by comparing our outcomes using two different approaches. Study Design Comparison of clinical data and outcomes of newborns at risk for EOS between two study periods, in which we have used two different protocols for their evaluation and management. Results Although outcomes were not different, adoption of the criteria suggested in the 2012 American Academy of Pediatrics guidelines in the second era resulted in increased utilization of diagnostic laboratory tests and increased use of empiric antibiotic treatments with less yield in a population with a low incidence of EOS (< 0.3/1,000 live births), such as ours. Conclusion In asymptomatic newborns at risk for EOS, careful assessment of a set of maternal, infant, and peripartum risk factors and their severity combined with careful clinical observation, judicious use of laboratory evaluations, and empiric antibiotic treatment only in selected cases seem to be appropriate.

Cannula With Long and Narrow Tubing vs Short Binasal Prongs for Noninvasive Ventilation in Preterm Infants: Noninferiority Randomized Clinical Trial.

Importance: Use of cannulas with long and narrow tubing (CLNT) has gained increasing popularity for applying noninvasive respiratory support for newborn infants thanks to ease of use, perceived patient comfort, and reduced nasal trauma. However, there is concern that this interface delivers reduced and suboptimal support. Objective: To determine whether CLNT is noninferior to short binasal prongs and masks (SPM) when providing nasal intermittent positive pressure ventilation (NIPPV) in preterm infants. Design, Setting, and Participants: This randomized controlled, unblinded, prospective noninferiority trial was conducted between December 2017 and December 2019 at 2 tertiary neonatal intensive care units. Preterm infants born between 24 weeks' and 33 weeks and 6 days' gestation were eligible if presented with respiratory distress syndrome with the need for noninvasive ventilatory support either as initial treatment after birth or after first extubation. Analysis was performed by intention to treat. Interventions: Randomization to NIPPV with either CLNT or SPM interface. Main Outcomes and Measures: The primary outcome was the need for intubation within 72 hours after NIPPV treatment began. Noninferiority margin was defined as 15% or less absolute difference. Results: Overall, 166 infants were included in this analysis, and infant characteristics and clinical condition (including fraction of inspired oxygen, Pco2, and pH level) were comparable at recruitment in the CLNT group (n = 83) and SPM group (n = 83). The mean (SD) gestational age was 29.3 (2.2) weeks vs 29.2 (2.5) weeks, and the mean (SD) birth weight was 1237 (414) g vs 1254 (448) g in the CLNT and SPM groups, respectively. Intubation within 72 hours occurred in 12 of 83 infants (14%) in the CLNT group and in 15 of 83 infants (18%) in the SPM group (risk difference, -3.6%; 95% CI, -14.8 to 7.6 [within the noninferiority margin], χ2 P = .53). Moderate to severe nasal trauma was significantly less common in the CLNT group compared with the SPM group (4 [5%] vs 14 [17%]; P = .01). There were no differences in other adverse events or in the course during hospitalization. Conclusions and Relevance: In this study, CLNT was noninferior to SPM in providing NIPPV for preterm infants, while causing significantly less nasal trauma.

First report of paracoccidioidomycosis reactivation as a complication of immunosuppressive therapy for acute severe colitis in a caving enthusiast.

Treatment for ulcerative colitis often requires the administration of immunosuppressive therapy. Shortly after rescue therapy with infliximab for acute severe colitis, a patient who was also taking corticosteroids, azathioprine and adalimumab became rapidly unwell with atypical pneumonia, which did not respond to conventional antimicrobials. Re-examining the travel history revealed a prior caving trip to Costa Rica. Dimorphic fungal serology was thus tested and a diagnosis of paracoccidioidomycosis was made. After a lengthy intensive care unit admission, the patient made a recovery after the administration of appropriate antifungal therapy and was discharged home on long-term oral antifungals.

A randomized pilot study comparing heated humidified high-flow nasal cannulae with NIPPV for RDS.

OBJECTIVE: To compare the requirement for endotracheal ventilation in preterm infants treated with heated, humidified high-flow nasal cannula (HHHFNC) with those treated with nasal intermittent positive pressure ventilation (NIPPV) for the primary treatment of respiratory distress syndrome (RDS). STUDY DESIGN: Randomized, controlled, prospective, single-center pilot study. Infants (gestational age [GA] <35 weeks, birth weight [BW] >1,000 g) with RDS were randomly assigned to receive HHHFNC (38 infants) delivered by Vapotherm® device (Precision Flow™ or 2000 i, Vapotherm Inc., Stevensville, MD), at flows between 1.0 and 5.0 L/min, or NIPPV (38 infants) delivered by the SLE 2000 or 5000. Surfactant was administered as rescue therapy. Analysis was done by intention-to-treat. RESULTS: Infant's characteristics ([mean ± SD] GA 31.8 ± 2.3 vs. 32.0 ± 2.3 weeks) and cardio-respiratory status at study entry (FiO2 0.25 ± 0.05 vs. 0.26 ± 0.07; SpO2 90 ± 6% vs. 87 ± 12; PCO2 54.4 ± 10.4 vs. 52.6 ± 8.0 mmHg) were comparable for the HHHFNC and NIPPV groups. There was no significant difference in the need for endotracheal ventilation (28.9% vs. 34.2%) between HHHFNC and NIPPV groups. One infant failed HHHFNC and succeeded on NIPPV. The rate of neonatal morbidities (pneumothorax, bronchopulmonary dysplasia, intra-ventricular hemorrhage, necrotizing enterocolitis, patent ductus arteriosus, and nasal trauma) was comparable in both groups. Duration of nasal support was longer with HHHFNC compared with NIPPV (5.4 ± 4.0 vs. 2.6 ± 1.9 days, P = 0.006) but the duration of endotracheal ventilation, time to full feeds, and length of stay were comparable. CONCLUSIONS: Our pilot study suggests that HHHFNC maybe as effective as NIPPV in preventing endotracheal ventilation in the primary treatment of RDS in premature infants (<35 weeks GA and BW >1,000 g).
