RESUMEN

OBJECTIVE: Evaluate the association between results of the room air (RA) challenge and death, respiratory morbidity, and neurodevelopmental impairment (NDI) at 2 years' corrected age. STUDY DESIGN: Cohort study of infants born <27 weeks' gestational age who underwent a RA challenge to determine BPD diagnosis at 36 weeks postmenstrual age. RESULTS: Of 1022 infants eligible for the RA challenge, 554 underwent testing and 223 passed. Test result was not associated with death or serious respiratory morbidities [adjusted relative risk (aRR) 1.01, 95% confidence interval (CI) 0.65-1.56] or death or moderate/severe NDI (aRR 1.06, 95% CI 0.81-1.39) at 2 years. CONCLUSION: Results of the RA challenge were not associated with differences in respiratory or neurodevelopmental morbidity at 2 years, suggesting the RA challenge does not add prognostic value in contemporary extremely preterm infants.

RESUMEN

OBJECTIVE: Examine pathogen distribution, antibiotic resistance patterns, and hospital outcomes of infants with bacterial meningitis in neonatal intensive care units (NICUs) in the US from 2013-2018. STUDY DESIGN: Infants were divided into 2 groups based on age at the time of meningitis: early-onset (0-3 days) and late-onset (>3 days). We compared demographics, clinical characteristics, epidemiology, hospital outcomes, distribution of organisms and resistance, and blood culture timing relative to cerebrospinal fluid culture. RESULTS: From 345 NICUs, 659 infants were diagnosed with bacterial meningitis. The cumulative incidence was 1.1-1.3 cases/1000 NICU discharges. Median gestational age was 33 weeks, median birth weight was 1910 grams, 12% failed hearing screening, and 9% died prior to discharge. Of 141 cases of E. coli meningitis, 53% were resistant to ampicillin. CONCLUSIONS: Significant morbidities occur in infants with culture-proven meningitis in NICUs. Culture and subsequent discernment of sensitivity are crucial to guide definitive therapy.

RESUMEN

OBJECTIVE: To characterize demographics and trends in length of stay (LOS), morbidities, and mortality in late preterm infants. STUDY DESIGN: Cohort study of infants born between 34 0/7 and 36 6/7 weeks gestation between 1999 and 2018 without major congenital anomalies at Pediatrix Medical Group neonatal intensive care units (NICUs). RESULTS: 307,967 infants from 410 NICUs met inclusion criteria. The median (25th-75th percentile) LOS was 11 (8-16) days in the entire period. Postmenstrual age (PMA) at discharge increased during the cohort for all gestational ages (p < 0.001). There was a decrease in invasive ventilation, receipt of phototherapy, and reflux medications observed (p < 0.001). CONCLUSION: In this large cohort, given 20 years of time for medical advancement, there was no significant improvement in the LOS of late preterm infants. All infants had an increased PMA at discharge, despite multiple practice changes that were observed.

RESUMEN

BACKGROUND: Chorioamnionitis is a risk factor for fetal and neonatal outcomes. Therefore, predicting histological chorioamnionitis (HCA) and neonatal outcomes using clinical parameters could be helpful in management and preventing morbidities. OBJECTIVE: To determine if parameters of clinical chorioamnionitis (CCA) would be associated with HCA and neonatal outcomes. STUDY DESIGN: In this cohort study using a retrospective design, we analyzed the performance of signs of CCA in predicting HCA, and neonatal outcomes. Data were extracted from the electronic health record for all neonates with documented CCA delivered at our institution from 2011 to 2016. We compared our findings based on the old ACOG definition of CCA and the new definition released in 2017 - maternal fever plus any of fetal tachycardia, maternal leukocytosis, and purulent vaginal discharge. Maternal tachycardia and uterine tenderness were removed from the new criteria. Neonatal laboratory samples on admission, 12 h and 24 h were used to define the three time points of neonatal suspected sepsis. RESULTS: There were 530 mothers-infant dyads with chorioamnionitis. Seventy-three were preterm, and 457 were term. Eighty-eight percent of the preterm mothers had CCA, and HCA was present in 62.5% of 72 preterm placentas. Preterm infants with placental HCA significantly had lower birth weight, gestational age, placental weight, and more infants with lower 5-minute Apgar scores, compared to those with no HCA. In preterm infants, maternal urinary tract infection was significantly associated with decreased odds for HCA (OR 0.22, CI 0.10 - 0.71). More preterm babies with suspected sepsis criteria at the 3 time points had HCA (all p ≤ .01). In the term cohort, 95.4% and 65.6% had CCA and HCA, respectively. In term infants (n = 457), maternal leukocytosis (p = .002) and prolonged rupture of membranes (PROM; p = 002) were associated with HCA. Suspected sepsis was associated with PROM (p = .04), HCA (p = .0001), and maternal leukocytosis (p ≤ .05) in at least 1 of the 3 time points. CONCLUSION: Though maternal leukocytosis was significantly associated with the presence of HCA in the term cohort, there were no CCA criteria that accurately predicted presence of HCA in either the preterm or the term infants.

RESUMEN

Importance: Pulmonary rehabilitation (PR) after exacerbation of chronic obstructive pulmonary disease (COPD) is effective in reducing COPD hospitalizations and mortality while improving health-related quality of life, yet use of PR remains low. Estimates of the cost-effectiveness of PR in this setting could inform policies to improve uptake. Objective: To estimate the cost-effectiveness of participation in PR after hospitalization for COPD. Design, Setting, and Participants: This economic evaluation estimated the cost-effectiveness of participation in PR compared with no PR after COPD hospitalization in the US using a societal perspective analysis. A Markov microsimulation model was developed to estimate the cost-effectiveness in the US health care system with a lifetime horizon, 1-year cycle length, and a discounted rate of 3% per year for both costs and outcomes. Data sources included published literature from October 1, 2001, to April 1, 2021, with the primary source being an analysis of Medicare beneficiaries living with COPD between January 1, 2014, and December 31, 2015. The analysis was designed and conducted from October 1, 2019, to December 15, 2021. A base case microsimulation, univariate analyses, and a probabilistic sensitivity analysis were performed. Interventions: Pulmonary rehabilitation compared with no PR after COPD hospitalization. Main Outcomes and Measures: Net cost in US dollars, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio. Results: Among the hypothetical cohort with a mean age of 76.9 (age range, 60-92) years and 58.6% women, the base case microsimulation from a societal perspective demonstrated that PR resulted in net cost savings per patient of $5721 (95% prediction interval, $3307-$8388) and improved quality-adjusted life expectancy (QALE) (gain of 0.53 [95% prediction interval, 0.43-0.63] years). The findings of net cost savings and improved QALE with PR did not change in univariate analyses of patient age, the Global Initiative for Obstructive Lung Disease stage, or number of PR sessions. In a probabilistic sensitivity analysis, PR resulted in net cost savings and improved QALE in every one of 1000 samples and was the dominant strategy in 100% of simulations at any willingness-to-pay threshold. In a 1-way sensitivity analysis of total cost, assuming completion of 36 sessions, a single PR session would remain cost saving to $171 per session and had an incremental cost-effectiveness ratio of $884 per session for $50 000/QALY and $1597 per session for $100 000/QALY. Conclusions and Relevance: In this economic evaluation, PR after COPD hospitalization appeared to result in net cost savings along with improvement in QALE. These findings suggest that stakeholders should identify policies to increase access and adherence to PR for patients with COPD.

RESUMEN

BACKGROUND: There has been a 291% relative increase in congenital syphilis (CS) cases in the United States from 2015 to 2019. Although the majority of affected fetuses/infants are stillborn or are asymptomatic, a subset is born with severe clinical illness. We describe a series of severe CS cases in the neonatal intensive care unit. METHODS: Retrospective review of infants with CS, admitted to the Duke Intensive Care Nursery from June 2016 to February 2020. We recorded birthweight, gestational age, medications, procedures, diagnoses, laboratory data and outcomes. Severe symptoms included: birth depression, hypoxic ischemic encephalopathy (HIE), disseminated intravascular coagulopathy and/or persistent pulmonary hypertension (PPHN). RESULTS: Seven infants with CS were identified and 5 with severe presentations were included. Median gestational age was 35.1 weeks (range: 29-37 weeks, median: 35 weeks). All infants required intubation at birth, 2 required chest compressions and epinephrine in the delivery room. One had hydrops fetalis and died in the delivery room. All 4 surviving infants had HIE, severe PPHN, hepatitis and seizures. All infants had a positive rapid plasma reagin, and were treated with penicillin G. Maternal rapid plasma reagin was pending for 3 of 5 infants at delivery, and later returned positive; 2 were positive during pregnancy but not treated. Other infectious work-up was negative. Three infants survived to discharge. CONCLUSION: CS can be associated with HIE, PPHN and disseminated intravascular coagulopathy in affected infants. Clinicians should have a high index of suspicion and include CS in their differential diagnoses. This study also highlights the importance of adequate treatment of identified cases and screening during the third trimester and at delivery.

RESUMEN

Invasive fungal infections remain the leading causes of morbidity and mortality in neonates, especially preterm and very low birth weight infants. Most invasive fungal infections are due to Candida or Aspergillus species, and other fungi are increasingly reported and described. Appropriate identification and treatment are required to augment activity and reduce the toxicity of antifungal drugs. Successful use of antifungals in the vulnerable neonatal population is important for both prevention and treatment of infection. Strategies for prevention, including prophylactic antifungal therapy as well as reducing exposure to modifiable risk factors, like limiting antibiotic exposure, discontinuation of central catheters, and hand hygiene are key techniques to prevent and decrease rates of invasive fungal infections. In conclusion, this is a review of the most common causes, prevention strategies, prophylaxis, and treatment of invasive fungal infections in neonates.

RESUMEN

Bronchopulmonary dysplasia (BPD) is a common morbidity affecting preterm infants and is associated with substantial long-term disabilities. There has been no change in the incidence of BPD over the past 20 years, despite improvements in survival and other outcomes. The preterm lung is vulnerable to injuries occurring as a result of invasive ventilation, hyperoxia, and infections that contribute to the development of BPD. Clinicians caring for infants in the neonatal intensive care unit use multiple therapies for the prevention and management of BPD. Non-invasive ventilation strategies and surfactant administration via thin catheters are treatment approaches that aim to avoid volutrauma and barotrauma to the preterm developing lung. Identifying high-risk infants to receive postnatal corticosteroids and undergo patent ductus arteriosus closure may help to individualize care and promote improved lung outcomes. In infants with established BPD, outpatient management is complex and requires coordination from several specialists and therapists. However, most current therapies used to prevent and manage BPD lack solid evidence to support their effectiveness. Further research is needed with appropriately defined outcomes to develop effective therapies and impact the incidence of BPD.

RESUMEN

BACKGROUND: All scoring systems used in Alopecia Areata (AA) focus mainly on scalp and cannot assess the severity or treatment response when AA involves the beard hair, eyebrows, or eyelashes. AIM: This study describes and assesses the reliability of a new scoring system "Alopecia Areata Severity Index" (AASI) for measuring the severity of AA of scalp, beard, and upper face. METHODS: Scalp hair, beard hair, upper face (eyebrows and eyelashes) were individually assessed and the severity of AA was scored from 0 to 100 (0-50 in case of upper face). AASI score was then calculated as a sum of all these individual scores as AASI = AASI (scalp) + AASI (upper face) + AASI (beard)+. To test the inter-observer reliability of AASI score, 25 patients with varying severity of AA were scored by 4 trained dermatologists. Repeat scoring was performed after one week to test for intra-observer reliability. RESULTS: Excellent inter-rater, as well as intra-observer reliability, was observed with Chronbach's alpha value of 0.999 (CI = 0.989-1.000). The intra-observer correlation coefficient with average measure was 0.999 (CI = 0.990-1.000) with statistically significant F test <0.005. CONCLUSION: AASI score is a reliable scoring system to assess the severity of AA in patients with involvement of one or more areas of the body. LIMITATIONS: Sample population belonged to single ethnic group.

RESUMEN

OBJECTIVE: The management of early hypotension in extremely low gestational age neonates (ELGANs) varies greatly between centers. The objective of this study was to provide updated data on the use of vasoactive medications in ELGANs during the first postnatal week. STUDY DESIGN: We identified ELGANs (22-27 weeks gestational age) cared for at Pediatrix neonatal intensive care units from 2009 to 2018. We evaluated the frequency of exposure to vasoactive medications by gestational age, and compared use of vasoactive medications between two epochs (2009-2013 and 2014-2018). RESULTS: A total of 10,070/34,234 (29%) ELGANs received ≥1 vasoactive medication. Dopamine was the most frequently used vasoactive medication. The majority (83%) of treated ELGANs initiated therapy on postnatal days 0-1. Overall use of vasoactive medications was slightly lower in 2014-2018 than 2009-2013 (28 vs 31%, p < 0.001). CONCLUSION: A substantial proportion of ELGANs were exposed to vasoactive medications during the first postnatal week.

RESUMEN

OBJECTIVE: Characterize association between hydrocortisone receipt and hospital outcomes of infants with persistent pulmonary hypertension of the newborn (PPHN). STUDY DESIGN: Cohort study of infants ≥34 weeks with PPHN who received inhaled nitric oxide at <7 days of age (2010-2016). We generated propensity scores, and performed inverse probability-weighted regression to estimate hydrocortisone effect on outcomes: death, chronic lung disease (CLD), oxygen at discharge. RESULTS: Of 2743 infants, 30% received hydrocortisone, which was associated with exposure to mechanical ventilation, sedatives, paralytics, or vasopressors (p < 0.001). There was no difference in death, CLD, or oxygen at discharge. In infants with meconium aspiration syndrome, hydrocortisone was associated with decreased oxygen at discharge (odds ratio 0.56; 95% confidence interval 0.21, 0.91). CONCLUSIONS: There was no association between hydrocortisone receipt and death, CLD, or oxygen at discharge in our cohort. Prospective studies are needed to evaluate the effectiveness of hydrocortisone in infants with PPHN.

RESUMEN

Introduction: Infections during pregnancy are a preventable public health concern globally, with the highest burden occurring in low- and middle-income countries. Despite clear interventions to reduce these infections, their impact on preventing stillbirths is unclear, with conflicting evidence.Areas covered: The purpose of this review is to discuss data regarding infectious causes of stillbirths, and interventions for the prevention and/or treatment of these infections. We discuss the limitations in evaluating the true effect of the interventions on stillbirths, and highlight the importance of preventing infections in the grand scheme of improving maternal and infant pregnancy outcomes. We used PubMed to identify relevant studies, reviews, and meta-analysis until January 2021.Expert opinion: Maternal infections during pregnancy, especially malaria and syphilis, are notable causes of stillbirth in low- and middle-income countries. Despite considerable global advocacy, there is scant recognition of the potential to reduce the burden of antepartum stillbirths related to infections. Reducing stillbirths overall must become an important indicator for quality of care and accountability, and progress must also be assessed by coverage of key interventions that impact stillbirths, which includes population-based screening, prevention and timely treatment of infections during pregnancy.

RESUMEN

Suspected or proven late onset sepsis, necrotizing enterocolitis, urinary tract infections, and ventilator associated pneumonia occurring after the first postnatal days contribute significantly to the total antibiotic exposures in neonatal intensive care units. The variability in definitions and diagnostic criteria in these conditions lead to unnecessary antibiotic use. The length of treatment and choice of antimicrobial agents for presumed and proven episodes also vary among centers due to a lack of supportive evidence and guidelines. Implementation of robust antibiotic stewardship programs can encourage compliance with appropriate dosages and narrow-spectrum regimens.

RESUMEN

INTRODUCTION: Allergic contact dermatitis (ACD) is a growing concern due to increased use of cosmetics and topical medications routinely and exposure to a large number of allergens on day-to-day basis. Patch testing is a reliable method for detecting the causative antigens in suspected cases. AIMS AND OBJECTIVES: To assess the demographic profile, pattern of ACD, and patch test profile of suspected cases of ACD attending contact dermatitis clinic of our department. MATERIALS AND METHODS: It was a retrospective study in which all the data enrolled in the contact dermatitis clinic of our department over a 7-year period were analyzed. Patch testing was done using the Indian Standard Series of 20 antigens primarily, and other batteries were used depending on patient requirement and availability. RESULTS: A total of 582 patients were enrolled in the contact dermatitis clinic over a period of 7 years. Hand eczema was the most common pattern seen in 268 cases followed by feet eczema, hand and foot eczema, facial eczema, forearm and leg eczema and photoallergic contact eczema. A total of 177 patients (30.4%) gave positive patch test results, with nickel sulfate being the most common allergen identified followed by potassium dichromate, cobalt sulfate, paraphenylenediamine, neomycin sulfate, and fragrance mix. CONCLUSION: Common allergens identified in our study were more or less similar to studies from other parts of India. However, due to the unique climate of the valley, the profile of parthenium sensitivity was low in our study when compared to the rest of the country.

RESUMEN

Meningitis is a devastating infection in infants and is linked to adverse long-term outcomes. The prevalence of meningitis is variable and depends on gestational age, postnatal age, and clinical setting. Early diagnosis and treatment with appropriate antibiotics are crucial to decrease the risk of morbidity and mortality. Lumbar punctures are essential for the diagnosis of meningitis, but clinicians may defer lumbar puncture if the risk for meningitis is low or if there are substantial concerns regarding the risk associated with the procedure. Awareness of the epidemiology and microbiology of meningitis in infants, as well as valid contraindications to performing a lumbar puncture, is necessary to avoid missed diagnoses and procedure-related adverse effects.

RESUMEN

Little is known about antibiotic prescribing differences between academic and community outpatient settings. This retrospective, cross-sectional chart review compares compliance with Infectious Diseases Society of America and American Academy of Pediatrics prescribing guidelines for otitis media, sinusitis, and pharyngitis in academic and affiliated community practices. The study results for correct antibiotic prescribing rate in the academic setting (67%) compared with the community setting (21%) demonstrate the urgent need for stewardship in community outpatient clinics.
