RESUMEN
Epidemiologic studies suggest that prenatal exposures to certain viruses may influence early neurodevelopment, predisposing offspring to neuropsychiatric conditions later in life. The long-term effects of maternal COVID-19 infection in pregnancy on early brain development, however, remain largely unknown. We prospectively enrolled infants in an observational cohort study for a single-site study in the Washington, DC Metropolitan Area from June 2020 to November 2021 and compared these infants to pre-pandemic controls (studied March 2014-February 2020). The primary outcomes are measures of cortical morphometry (tissue-specific volumes), along with global and regional measures of local gyrification index, and sulcal depth. We studied 210 infants (55 infants of COVID-19 unexposed mothers, 47 infants of COVID-19-positive mothers, and 108 pre-pandemic healthy controls). We found increased cortical gray matter volume (182.45 ± 4.81 vs. 167.29 ± 2.92) and accelerated sulcal depth of the frontal lobe (5.01 ± 0.19 vs. 4.40 ± 0.13) in infants of COVID-19-positive mothers compared to controls. We found additional differences in infants of COVID-19 unexposed mothers, suggesting both maternal viral exposures, as well as non-viral stressors associated with the pandemic, may influence early development and warrant ongoing follow-up.

BACKGROUND: The increasing prevalence of Americans with multiple (2 or more) chronic conditions raises concerns about the appropriateness and applicability of clinical practice guidelines for patient management. Most guidelines clinicians currently rely on have been designed with a single chronic condition in mind, and many such guidelines are inattentive to issues related to comorbidities. PURPOSE: In response to the need for guideline developers to address comorbidities in guidelines, the Department of Health and Human Services convened a meeting in May 2012 in partnership with the Institute of Medicine to identify principles and action options. RESULTS: Eleven principles to improve guidelines' attentiveness to the population with multiple chronic conditions were identified during the meeting. They are grouped into 3 interrelated categories: (1) principles intended to improve the stakeholder technical process for developing guidelines; (2) principles intended to strengthen content of guidelines in terms of multiple chronic conditions; and (3) principles intended to increase focus on patient-centered care. CONCLUSION: This meeting built upon previously recommended actions by identifying additional principles and options for government, guideline developers, and others to use in strengthening the applicability of clinical practice guidelines to the growing population of people with multiple chronic conditions. The suggested principles are helping professional societies to improve guidelines' attentiveness to persons with multiple chronic conditions.

BACKGROUND: Many women stop smoking during pregnancy. Factors associated with relapse are known, but no intervention prevents the return to smoking among pregnant women. The objective of this study was to determine why women return to smoking after prolonged abstinence during pregnancy by examining mothers' intention to smoke at the time of delivery and the perceptions that shape their intention. METHODS: We conducted in-depth, semi-structured interviews during their postpartum hospital stay with 24 women who stopped smoking while pregnant. We asked participants whether they intended to resume smoking after pregnancy and why. Transcripts were analyzed using grounded theory-based qualitative methods to identify themes. RESULTS: Participants ranged in age from 18 to 36 years, and 63 percent were white. Three themes emerged from the interviews with the mothers: 1) they did not intend to return to smoking but doubted whether they would be able to maintain abstinence; 2) they believed that it would be possible to protect their newborns from the harms of cigarette smoke; and 3) they felt that they had control over their smoking and did not need help to maintain abstinence after pregnancy. CONCLUSIONS: Although most participants did not intend to resume smoking, their intentions may be stymied by their perceptions about second-hand smoke and by their overestimation of their control over smoking. Further study should quantify these barriers and determine their evolution over the first year after pregnancy with the goal of informing more successful, targeted interventions.

While up to 45% of women quit smoking during pregnancy, nearly 80% return to smoking within a year after delivery. Interventions to prevent relapse have had limited success. The study objective was to understand what influences return to smoking after pregnancy among women who quit smoking during pregnancy, with a focus on the role of social networks. We conducted in-depth, semi-structured interviews during the postpartum hospital stay with women who quit smoking while pregnant. Over 300 pages of transcripts were analyzed using qualitative methods to identify common themes. Respondents [n = 24] were predominately white (63%), had at least some college education (54%) and a mean age of 26 years (range = 18-36). When reflecting on the experience of being a smoker who quit smoking during pregnancy, all participants emphasized the importance of their relationships with other smokers and the changes in these relationships that ensued once they quit smoking. Three common themes were: (1) being enmeshed in social networks with prominent smoking norms (2) being tempted to smoke by members of their social networks, and (3) changing relationships with the smokers in their social networks as a result of their non-smoking status. We found that women who quit smoking during pregnancy found themselves confronted by a change in their social network since most of those in their social network were smokers. For this reason, smoking cessation interventions may be most successful if they help women consider restructuring or reframing their social network.

Human milk provides optimal nutrition for term newborns, but the prevalence of its use is below target, and risks have been identified. Infants of black mothers as well as term newborns admitted to the neonatal intensive care unit are at risk for not receiving human milk. To improve human milk intake, multiple individual-level interventions have been shown to be effective, but some popular system-level interventions are ineffective or harmful. Expressed milk and donor milk may be less beneficial than direct breastfeeding. Nuanced public policies can help support lactation while promoting individual choice and equity.

OBJECTIVES: To evaluate newborn pulse oximetry screening (POS) outcomes at a large community hospital and the impact of the recommended revised POS algorithm. METHODS: A retrospective cohort study was performed to evaluate the results of POS in the well-infant nursery between 2012 and 2020. The POS results were obtained from an electronic platform. Chart review was completed for newborns with failed screens. The recommended revision to POS, no second rescreen, was applied to the data to evaluate screening outcomes. RESULTS: Of the total 65 414 infants admitted to the well-infant nursery during this 8-year period, >99% (n = 64 780) received POS. Thirty-one infants failed POS (4.6 per 10 000 screened). All infants who failed POS were found to have a disorder, with 12 (39%) having critical congenital heart disease (CCHD), 9 (29%) having non-CCHD requiring further follow-up, and 10 (32%) having noncardiac conditions. One false-negative screen result was identified through the Maryland Department of Health Newborn Screening Follow-up Program. The positive predictive value of POS for those screened was 39% for CCHD, with a specificity of 99.97%. Eliminating the second rescreen in the POS algorithm would have resulted in an additional 5 newborns without CCHD failing POS, increasing the false-positive rate from 0.03% to 0.04%. CONCLUSIONS: POS is an effective tool for identifying CCHD and secondary conditions. POS was successfully implemented with few missed screens and was highly specific. Elimination of the second rescreen in the pulse oximetry algorithm would have resulted in a minimal increase in false-positive results and faster evaluation of newborns with CCHD.

To assess confidence in resuscitation skills among pediatric residents and its relationship to training and experience, all pediatric residents at one institution were surveyed regarding their confidence in technical and leadership resuscitation skills and their prior experience with real and mock codes. Respondents (61/82, 74%) reported participation in 4.9 +/- 3.6 mock and 3.9 +/- 5.0 real codes. Confidence score for all skills was 2.7 +/- 0.6 (scale 1-5). Senior residents were more confident than interns (2.8 +/- 0.5 vs 2.3 +/- 0.5). Residents were more confident in basic (3.9 +/- 0.6) than in advanced (2.6 +/- 0.6) or expert resuscitation skills (1.6 +/- 0.7). Confidence correlated with mock codes (r = 0.52) and to a lesser degree with real codes attended (r = 0.36). Performance of active roles and debriefing occurred more commonly with mock than with real codes. The data indicate that pediatric residents have limited confidence in resuscitation skills and that mock code training with active participation and debriefing may be an effective educational tool.

BACKGROUND AND OBJECTIVES: The extent to which clinicians use currently available guidelines for early-onset sepsis (EOS) screening has not been described. The Better Outcomes through Research for Newborns network represents 97 nurseries in 34 states across the United States. The objective of this study was to describe EOS risk management strategies across a national sample of newborn nurseries. METHODS: A Web-based survey was sent to each Better Outcomes through Research for Newborns network nursery site representative. Nineteen questions addressed specific practices for assessing and managing well-appearing term newborns identified at risk for EOS. RESULTS: Responses were received from 81 (83%) of 97 nurseries located in 33 states. Obstetric diagnosis of chorioamnionitis was the most common factor used to identify risk for EOS (79 of 81). Among well-appearing term infants with concern for maternal chorioamnionitis, 51 of 79 sites used American Academy of Pediatrics or Centers for Disease Control and Prevention guidelines to inform clinical care; 11 used a published sepsis risk calculator; and 2 used clinical observation alone. Complete blood cell count (94.8%) and C-reactive protein (36.4%) were the most common laboratory tests obtained and influenced duration of empirical antibiotics at 13% of the sites. Some degree of mother-infant separation was required for EOS evaluation at 95% of centers, and separation for the entire duration of antibiotic therapy was required in 40% of the sites. CONCLUSIONS: Substantial variation exists in newborn EOS risk assessment, affecting the definition of risk, the level of medical intervention, and ultimately mother-infant separation. Identification of the optimal approach to EOS risk assessment and standardized implementation of such an approach could affect care of a large proportion of newborns.

BACKGROUND: Transcutaneous bilirubin (TcB) meters are widely used for screening newborns for jaundice, with a total serum bilirubin (TSB) measurement indicated when the TcB value is classified as "positive" by using a decision rule. The goal of our study was to assess the clinical utility of 3 recommended TcB screening decision rules. METHODS: Paired TcB/TSB measurements were collected at 34 newborn nursery sites. At 27 sites (sample 1), newborns were routinely screened with a TcB measurement. For sample 2, sites that typically screen with TSB levels also obtained a TcB measurement for the study. Three decision rules to define a positive TcB measurement were evaluated: ≥75th percentile on the Bhutani nomogram, 70% of the phototherapy level, and within 3 mg/dL of the phototherapy threshold. The primary outcome was a TSB level at/above the phototherapy threshold. The rate of false-negative TcB screens and percentage of blood draws avoided were calculated for each decision rule. RESULTS: For sample 1, data were analyzed on 911 paired TcB-TSB measurements from a total of 8316 TcB measurements. False-negative rates were <10% with all decision rules; none identified all 31 newborns with a TSB level at/above the phototherapy threshold. The percentage of blood draws avoided ranged from 79.4% to 90.7%. In sample 2, each rule correctly identified all 8 newborns with TSB levels at/above the phototherapy threshold. CONCLUSIONS: Although all of the decision rules can be used effectively to screen newborns for jaundice, each will "miss" some infants with a TSB level at/above the phototherapy threshold.

OBJECTIVE: To characterize discrepancies between transcutaneous bilirubin (TcB) measurements and total serum bilirubin (TSB) levels among newborns receiving care at multiple nursery sites across the United States. METHODS: Medical records were reviewed to obtain data on all TcB measurements collected during two 2-week periods on neonates admitted to participating newborn nurseries. Data on TSB levels obtained within 2 hours of a TcB measurement were also abstracted. TcB--TSB differences and correlations between the values were determined. Data on demographic information for individual newborns and TcB screening practices for each nursery were also collected. Multivariate regression analysis was used to identify characteristics independently associated with the TcB--TSB difference. RESULTS: Data on 8319 TcB measurements were collected at 27 nursery sites; 925 TSB levels were matched to a TcB value. The mean TcB--TSB difference was 0.84 ± 1.78 mg/dL, and the correlation between paired measurements was 0.78. In the multivariate analysis, TcB--TSB differences were 0.67 mg/dL higher in African-American newborns than in neonates of other races (P < .001). The TcB--TSB difference also varied significantly based on brand of TcB meter used and hour of age of the infant. For 2.2% of paired measurements, the TcB measurement underestimated the TSB level by ≥ 3 mg/dL. CONCLUSIONS: During routine clinical care, TcB measurement provided a reasonable estimate of TSB levels in healthy newborns. Discrepancies between TcB and TSB levels were increased in African-American newborns and varied based on brand of meter used.

BACKGROUND: In some patients with vitamin B-12 deficiency mistakenly treated with folic acid, anemia resolved but neurologic complications became worse (masking). Fortification of enriched cereal grains with folic acid has raised concerns that people who consume large quantities of cereal grains, particularly the elderly, may be at increased risk of masking. It is unclear, however, what proportion of people with low vitamin B-12 concentrations do not have anemia and whether the proportion is increasing. OBJECTIVE: We investigated whether fortification has increased the proportion of patients with low vitamin B-12 but without anemia. DESIGN: We reviewed the laboratory results of every patient for whom a vitamin B-12 concentration was measured at the Veterans Affairs Medical Center in Washington, DC, between 1992 and 2000. Those with a low vitamin B-12 concentration (< 258 pmol/L) had their hematocrits and mean cell volumes checked. The proportion without anemia was examined by year before, during, and after folic acid fortification began. RESULTS: There were 1573 subjects with a low vitamin B-12 concentration. The proportion without anemia did not increase significantly from the prefortification period (39.2%) to the period of optional fortification (45.5%) and the postfortification period (37.6%). These findings did not change when the analysis was limited to patients aged > 60 y or when a more conservative definition of low vitamin B-12 (< 150 pmol/L) was used. CONCLUSIONS: Despite evidence that folic acid exposure has increased dramatically since food fortification began, this population showed no evidence of an increase in low vitamin B-12 concentrations without anemia. If confirmed, these results would indicate that food fortification has not caused a major increase in masking of vitamin B-12 deficiency.

BACKGROUND: There is a paucity of evidence to guide clinical management for term and late preterm newborns. The Better Outcomes through Research for Newborns (BORN) network is a national collaborative of clinicians formed to increase the evidence-base for well newborn care. OBJECTIVE: To develop a consensus-based, prioritized research agenda for well newborn care. DESIGN: A two-round modified Delphi survey of BORN members was conducted. Round 1 was an open-ended survey soliciting 5 clinical questions identified as important and under-researched. Using qualitative methods, 20 most common themes were extracted and transformed into research questions. Round 2 survey respondents ranked the top 20 questions using a 5- point Likert scale and a quantitative analysis was conducted. RESULTS: Round 1 survey generated 439 unique research questions that fell into 57 themes. In the Round 2 survey, the highest rated questions were: 1) At what weight-loss percentage is it medically necessary to formula supplement a breastfeeding infant? 2) What is the optimal management of infants with neonatal abstinence syndrome? 3) How and when should we initiate a workup for sepsis, and how should these newborns be managed? CONCLUSIONS: Research priorities of clinicians include criteria for medically indicated formula supplementation of the breastfed newborn, management of neonatal abstinence syndrome and management of newborns at-risk for sepsis.

OBJECTIVES: To determine the relationship between the advice mothers receive about infant sleep position and the actual position they place their infants in to sleep and to understand modifiers of that relationship, especially beliefs about infant comfort and safety. DESIGN: Cross-sectional, face-to-face interviews. SETTING: Women, Infants, and Children centers in the United States from 2006 to 2008. PARTICIPANTS: A total of 2299 predominantly African American mothers of infants younger than 8 months. MAIN EXPOSURE: Advice received and beliefs about infant sleep position. OUTCOME MEASURE: Usually supine infant sleep position. RESULTS: Advice for exclusively supine infant sleep position from family (OR, 1.6; 95% CI, 1.17-2.17), doctors (OR, 2.28; 95% CI, 1.77-2.93), nurses (OR, 1.46; 95% CI, 1.15-1.84), or the media (OR, 1.54; 95% CI, 1.22-1.95) was associated with usually placing an infant supine to sleep. Additional sources of advice for exclusively supine position significantly increase the odds that an infant will be placed supine. Mothers who believe an infant is comfortable supine are more likely to place their infants on their backs to sleep (OR, 4.05; 95% CI, 2.51-6.53). Mothers who believe an infant will choke on its back are less likely to place their infants supine (OR, 0.36; 95% CI, 0.24-0.54). CONCLUSION: Among predominantly African American mothers, increasing advice for exclusively supine sleep and addressing concerns about infant comfort and choking remain critical to getting more infants on their back to sleep.

Since the late 1980s recombinant human erythropoietin (r-EPO) has been studied as an alternative to packed red blood cell (RBC) transfusion for the treatment of anemia of prematurity in very low birth weight infants. Initial trials and reports focused on r-EPO's ability to prevent or treat anemia of prematurity with the goal of eliminating RBC transfusion but achieved limited success. New concerns about the safety of r-EPO administration have emerged. Past cost-benefit analyses of r-EPO administration versus transfusion for the treatment of anemia of prematurity have been nearly balanced. Autologous transfusion, blood-sparing technologies, changes in RBC transfusion technique and safety, and further elucidation of the risk-benefit ratio of r-EPO therapy may change the cost-benefit analysis.
