Abstract
BACKGROUND/OBJECTIVE To date, there is no published, formal assessment of all maternal risk factors for respiratory syncytial virus lower respiratory tract infection (RSV-LRTI) in infants. A systematic literature review and meta-analysis were undertaken to ascertain: What maternal risk factors are associated with an increased risk of RSV-LRTI in infants? METHODS The systematic literature review used explicit methods to identify, select and analyze relevant data. PubMed, Embase and the Cochrane Library were searched (November 2022) using terms regarding: (1) RSV/LRTI; (2) risk factors; (3) pregnant/postpartum population. Bayesian meta-analysis compared RSV hospitalization (RSVH) risk in infants born to mothers with or without certain risk factors. RESULTS A total of 2353 citations were assessed and 20 were included in the final review (10 individual studies; 10 pooled analyses). In 10 studies examining infants (<1 year) without comorbidities (primary outcome), 10 maternal risk factors were associated with RSV-LRTI/RSVH in multivariate analyses. Meta-analysis revealed smoking while pregnant increased infant RSVH risk by 2.01 (95% credible interval: 1.52-2.64) times, while breast-feeding was protective (0.73, 95% credible interval: 0.58-0.90). Risk scoring tools have reported that maternal risk factors contribute between 9% and 21% of an infant's total risk score for RSVH. CONCLUSIONS A greater understanding of maternal risk factors and their relative contribution to infant RSV-LRTI will enable more accurate assessments of the impact of preventive strategies.

Antibiotics, Analgesic Sedatives, and Antiseizure Medications Frequently Used in Critically Ill Neonates: A Narrative Review. CHILDREN (BASEL, SWITZERLAND) 2024; 11:871. [PMID: 39062320 PMCID: PMC11275925 DOI: 10.3390/children11070871] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/30/2024] [Revised: 07/09/2024] [Accepted: 07/11/2024] [Indexed: 07/28/2024]
Abstract
Antibiotic, analgesic sedative, and antiseizure medications are among the most commonly used medications in preterm/sick neonates, who are at high risk of nosocomial infections, central nervous system complications, and are exposed to numerous painful/stressful procedures. These severe and potentially life-threatening complications may have serious short- and long-term consequences and should be prevented and/or promptly treated. The reported variability in the medications used in neonates indicates the lack of adequate neonatal studies regarding their effectiveness and safety. Important obstacles contributing to inadequate studies in preterm/sick infants include difficulties in obtaining parental consent, physicians' unwillingness to recruit preterm infants, the off-label use of many medications in neonates, and other scientific and ethical concerns. This review is an update on the use of antimicrobials (antifungals), analgesics (sedatives), and antiseizure medications in neonates, focusing on current evidence or knowledge gaps regarding their pharmacokinetics, indications, safety, dosage, and evidence-based guidelines for their optimal use in neonates. We also address the effects of early antibiotic use on the intestinal microbiome and its association with long-term immune-related diseases, obesity, and neurodevelopment (ND). Recommendations for empirical treatment and the emergence of pathogen resistance to antimicrobials and antifungals are also presented. Finally, future perspectives on the prevention, modification, or reversal of antibiotic resistance are discussed.

Abstract
PURPOSE An ancient description of the competition between twins for first breath is found in the biblical story of Jacob and Esau (Genesis 25:26) when Jacob pulled his older brother's heel in the hope of becoming firstborn but to no avail. In this study, we sought to evaluate the short and long-term outcomes of twin pairs, comparing between the second- and first-born twin. METHODS A population-based cohort study, including dichorionic twin deliveries occurring between the years 1991 and 2021 at Soroka University Medical Center. A General estimation equation (GEE) was applied to adjust for confounders. The incidence of offspring's hospitalizations due to various medical conditions was compared. Kaplan-Meier survival analyses compared cumulative morbidity. Cox proportional hazards models were used to control for confounders. RESULTS 5507 twin deliveries met the inclusion criteria. Second-born twins had higher rates of cesarean deliveries, statistically significant in the GEE multivariable analysis. More first-twin fetuses were experiencing non-reassuring fetal heart rate patterns, although other obstetrical outcomes as well as mortality rates were comparable between groups. Second twins weighed lower than their older sibling (mean difference 33 g) and were more frequently SGA and low birthweight (1500-2500 g); (p < 0.05). Later during childhood, offspring of twin deliveries experienced notable morbidity due to infectious (23.8-24.1%), respiratory (10.5-10.9%), neurological (7.0-7.8%) and cardiovascular pathologies (1.7-1.9%) during childhood, that was unaffected by birth order. CONCLUSION Other than birthweight differences, the birth order of dichorionic twins is not associated with adverse neonatal health indices, nor does it predict excess risk for morbidity during childhood.

Abstract
Preeclampsia is a multisystemic clinical syndrome characterized by the appearance of new-onset hypertension and proteinuria or hypertension and end organ dysfunction even without proteinuria after 20 weeks of pregnancy or postpartum. Residing at the severe end of the spectrum of the hypertensive disorders of pregnancy, preeclampsia occurs in 3 to 8% of pregnancies worldwide and is a major cause of maternal and perinatal morbidity and mortality, accounting for 8-10% of all preterm births. The mechanism whereby preeclampsia increases the risk of the neurodevelopmental, cardiovascular, and metabolic morbidity of the mother's offspring is not well known, but it is possible that the preeclamptic environment induces epigenetic changes that adversely affect developmental plasticity. These developmental changes are crucial for optimal fetal growth and survival but may lead to an increased risk of chronic morbidity in childhood and even later in life. The aim of this review is to summarize both the short- and long-term effects of preeclampsia on offspring based on the current literature.

Infant Mode of Delivery Shapes the Skin Mycobiome of Prepubescent Children. Microbiol Spectr 2022; 10:e0226722.

Abstract
Characterizing the skin mycobiome is necessary to define its association with the host immune system, particularly in children. In this study, we describe the skin mycobiome on the face, ventral forearm, and calf of 72 prepubescent children (aged 1 to 10 years) and their mothers, based on internal transcribed spacer (ITS) amplicon sequencing. The age and delivery mode at birth are the most influential factors shaping the skin mycobiome. Compared with that of the vaginally born children, the skin mycobiome of caesarean-born children is assembled by predominantly deterministic niche-based processes and exhibits a more fragile microbial network at all three sampling sites. Moreover, vaginal delivery leads to clearer intra- and interindividual specialization of fungal structures with increasing age; this phenomenon is not observed in caesarean-born children. The maternal correlation with children also differs based on the mode of delivery; specifically, the mycobiomes of vaginally born children at younger ages are more strongly correlated with vagina-associated fungal genera (Candida and Rhodotorula), whereas those of caesarean-delivered children at elder age include more skin-associated and airborne fungal genera (Malassezia and Alternaria). Based on this ecological framework, our results suggest that the delivery mode is significantly associated with maturation of the skin fungal community in children. IMPORTANCE Human skin is permanently colonized by microbes starting at birth. The hygiene hypothesis suggests that a lack of early-life immune imprinting weakens the body's resilience against atopic disorders later in life. To better understand fungal colonization following early-life periods affected by interruption, we studied the skin mycobiomes of 73 children and their mothers. Our results suggest a differentiation of the skin mycobiomes between caesarean-born and vaginally born children. Caesarean-born children exhibit a mycobiome structure with more fitted deterministic niche-based processes, a fragile network, and an unchanged microbial dissimilarity over time. In vaginally born children, this dissimilarity increases with age. The results indicate that initial microbial colonization has a long-term impact on a child's skin mycobiome. We believe that these findings will inspire further investigations of the "hygiene hypothesis" in the human microbiome, especially in providing novel insights into influences on the development of the early-life microbiome.

Abstract
BACKGROUND AND GOALS While evidence suggests short-term benefits in neonatal morbidity and mortality from cesarean delivery of the fetus in breech presentation, the long-term implications for the offspring are less clear. To assess the implications of the mode of delivery on offspring's health, we have evaluated the long-term gastrointestinal (GI) morbidity of offspring with a breech presentation delivered in either way. MATERIALS AND METHODS A population-based retrospective cohort study including singleton deliveries in breech presentation occurring between 1991 and 2014 at a tertiary referral hospital. Incidence of hospitalizations of the offspring up to the age of 18 years involving GI morbidity was compared between those delivered via cesarean section or vaginally. A Kaplan-Meier survival curve compared cumulative GI morbidity. A Weibull parametric survival model controlled for confounders while accounting for repeated occurrence of mothers and dependence among siblings. RESULTS Overall, 86.9% (n=6376) of the 7337 fetuses in breech presentation, were delivered abdominally. Hospitalizations involving GI morbidity were higher in offspring delivered by cesarean section, specifically due to inflammatory bowel disease (IBD). Kaplan-Meier survival curve revealed the higher cumulative incidence of total GI morbidity and IBD specifically in the cesarean delivery group (P<0.001 and P=0.004, respectively). Using a Weibull parametric while controlling for relevant confounders, cesarean delivery emerged as an independent risk factor for long-term IBD-related morbidity of the offspring delivered in breech presentation (adjusted hazard ratio=3.18, 95% confidence interval: 1.47-6.87, P=0.003). CONCLUSION Cesarean delivery is associated with higher rates of hospitalizations due to IBD and total GI morbidity during childhood in term singleton in breech presentation.

Abstract
Asymptomatic bacteriuria (ASB) is a well-acknowledged infectious entity during pregnancy; yet its long-term implications are not well investigated. The present study aimed to test the association between maternal ASB during pregnancy and long-term offspring infectious hospitalizations. A population-based cohort analysis was conducted, comparing the incidence of long-term infectious-related hospitalizations of offspring born to mothers who were diagnosed with ASB during pregnancy, and those who did not have ASB. The study was conducted at a tertiary medical center and included all singleton deliveries between the years 1991 and 2014. Infectious morbidities were based on a predefined set of International Classification of Disease-9 codes. A Kaplan-Meier survival curve compared cumulative infectious hospitalization incidence between the groups, and a Cox regression model was used to adjust for confounding variables. During the study period, 212,984 deliveries met inclusion criteria. Of them, 5378 (2.5%) were diagnosed with ASB. As compared to offspring of non-ASB mothers, total long-term infectious hospitalizations were significantly higher among children to mothers who were diagnosed with ASB (13.1% vs. 11.1%, OR = 1.2, 95% CI 1.11-1.30, P ≤ 0.001). Likewise, a Kaplan-Meier curve demonstrated higher cumulative incidence of infectious hospitalizations among children born to mothers with ASB (log rank, P = 0.006). In the Cox regression model, while controlling for maternal age, diabetes mellitus, ethnicity, hypertensive disorders, and gestational age, maternal ASB was noted as an independent risk factor for long-term infectious morbidity in the offspring (adjusted HR = 1.1, 95% CI 1.01-1.17, P = 0.042). ASB during pregnancy increases offspring susceptibility to long-term infectious hospitalizations.

Abstract
OBJECTIVES One of the most common indications for intrapartum cesarean delivery (CD) is nonreassuring fetal heart rate (NRFHR) patterns. We aimed to study the long-term effect of CD due to NRFHR on the risk for subsequent childhood infectious morbidity-related hospitalizations of the offspring. STUDY DESIGN A population-based cohort study was performed, comparing total and different subtypes of infectious morbidity-related pediatric hospitalizations among offspring born by CD due to NRFHR versus labor dystocia (failure of labor to progress during the 1st or 2nd stage). The analysis included all singletons born between the years 1999-2014 at a single tertiary regional medical center. Infectious-related morbidities included hospitalizations involving a predefined set of International Classification of Diseases, 9th revision codes, as recorded in hospital computerized files. Infants with congenital malformations, multiple gestations, vaginal deliveries and vacuum failure were excluded from the analysis. Perinatal mortality cases were excluded from the long-term analysis. A Kaplan-Meier survival curve was used to compare the cumulative morbidity, and a Cox proportional hazards model was constructed to adjust for confounders. RESULTS The study population included 9956 newborns who met inclusion criteria; among them, 5810 (58%) were born by CD due to NRFHR, and 4146 (42%) were born via CD following labor dystocia with normal fetal heart rate (comparison group). Offspring born following NRFHR had higher rates of infectious morbidity-related hospitalizations (11.4% vs. 9.1%; odds ratio, 1.3; 95% confidence interval, 1.1-1.5; P < 0.01; Kaplan-Meier survival curve P < 0.01). The association remained significant and independent while adjusting for gestational age, maternal age and comorbidities, using a Cox proportional hazards model (adjusted hazard ratio, 1.3; 95% confidence interval, 1.2-1.4; P < 0.01). CONCLUSIONS In our population, CD due to NRFHR is a risk factor for pediatric infectious morbidity-related hospitalizations of the offspring.

Abstract
INTRODUCTION AND HYPOTHESIS Elective pre-labour Caesarean section (CS) delivery is widely regarded as the panacea for all pelvic floor dysfunction despite substantial epidemiological evidence that it is only partially protective. To demand a CS is also considered a right for the well-counselled patient, even without an elevated risk of incontinence or prolapse. In recent years there has been increasing data on possible adverse health outcomes for children delivered by CS over those delivered vaginally. This includes respiratory illness, atopic conditions, obesity, diabetes and other severe auto-immune diseases. Concern has also been raised over possible impacts on cognitive and neuropsychological development in these children. Often the response has been to dismiss these outcomes as a result of the indication for the CS birth such as antenatal compromise or maternal disease. However the marked increase in non-medical Caesarean delivery throughout many regions of the world has allowed us to better distinguish these contributing factors. METHODS This narrative review looks at some of the more recent evidence on adverse health and developmental outcomes associated with CS, particularly pre-labour CS and the implications for the long term health of our society. RESULTS Epidemiological studies and animal research indicate an increased risk of negative impacts on child physical health and neuro-cognitive development aftercaesarean section delivery, particularly pre-labour Caesarean section, compared with vaginal delivery. This elevated risk persists after correction forobstetric and maternal factors. CONCLUSION Caesarean section delivery can result in adverse outcomes for infant, maternal and societal wellbeing. Elective Caesarean section, purely to potentially minimise pelvic floor dysfunction, cannot be justified.

Abstract
OBJECTIVES To determine the association between cesarean delivery and childhood infections up to 13 years of age. STUDY DESIGN We conducted a longitudinal cohort study of 731 803 children born between 2006 and 2016 at all hospitals in the province of Quebec, Canada. We followed children born by cesarean, operative vaginal, and nonoperative vaginal delivery up to 13 years of age. Outcomes included hospitalization for otitis media, respiratory, infectious enteritis, and other infections. We estimated hazard ratios with 95% CIs for the association between mode of delivery and childhood infections, adjusted for patient characteristics. RESULTS At age 3-4 years, cesarean delivery was associated with a 1.07-fold greater risk of otitis media (95% CI, 1.03-1.11), a 1.15-fold greater risk of respiratory infection (95% CI, 1.09-1.22), and a 1.13-fold greater risk of infectious enteritis (95% CI, 1.03-1.25) compared with nonoperative vaginal delivery. However, operative vaginal delivery was associated with these same outcomes. Both cesarean and operative vaginal delivery were more strongly associated with infection hospitalization before age 1 year, but associations disappeared after 5 years. CONCLUSIONS Cesarean delivery is associated with infection hospitalization before but not after age 5 years. However, associations were also present for operative vaginal delivery, which suggests that mechanisms other than exposure to maternal vaginal flora explain the relationship.

Abstract
OBJECTIVE We set out to ascertain a possible association between mode of delivery (cesarean vs. vaginal delivery) and gastrointestinal hospitalization of the offspring. STUDY DESIGN A population based cohort analysis including all uncomplicated singleton deliveries occurring between the years 1991-2014 at a tertiary medical center was performed, comparing long-term gastrointestinal hospitalization of offspring, according to mode of delivery. Multiple gestations, fetuses with congenital malformations and perinatal deaths were excluded, as were cases of urgent cesarean delivery and pregnancy complications. Gastrointestinal hospitalizations (up to age 18 years) were defined using predefined ICD9 codes, as recorded in hospital records. A Kaplan Meier survival curve was constructed to compare cumulative incidence of first gastrointestinal hospitalizations. A Cox proportional hazard model was used to control for confounders. RESULTS During the study period 139,232 deliveries met the inclusion criteria; 13,242 (9.5%) of which were elective cesarean deliveries, and the remaining 125,990 (90.5%) were delivered vaginally. Cesarean delivery was associated with more offspring hospitalizations for gastrointestinal morbidity (p < .001). The Kaplan Meier survival curve demonstrated higher cumulative incidence of gastrointestinal hospitalizations in the cesarean delivery group (log rank test p < .001). Utilizing a Cox proportional hazards model to control for confounders, cesarean delivery was found to be an independent risk factor for long-term gastrointestinal hospitalization of the offspring (adjusted HR 1.409, 95%CI 1.306-1.521, p < .001). Specifically, inflammatory bowel disease was more common among offspring following cesarean delivery aHR 1.386 95% CI 1.215-1.582 p < .001. CONCLUSION Elective cesarean delivery is an independent risk factor for long-term gastrointestinal-related hospitalization of the offspring.

Abstract
OBJECTIVE Caesarean section (CS) interrupts mother-to-newborn microbial transfer at birth. Beyond the neonatal period, the impact of CS on offspring gut microbiota and their short-chain fatty acids (SCFAs) remains unclear. Here, we examine birth delivery mode (CS versus vaginal delivery) with the infant gut microbiota and faecal SCFAs measured 3 and 12 months after birth. DESIGN Longitudinal study. SETTING North Carolina. POPULATION In 2013-15, we enrolled pregnant women and followed up their offspring for 12 months. We asked a subset of participants, enrolled over a 3-month period, to provide faecal samples at the 3- and 12-month follow-up visits. METHODS AND MAIN OUTCOMES We sequenced the 16S rRNA V4 region with Illumina MiSeq and quantified SCFA concentrations using gas chromatography. We examined delivery mode with differential abundance of microbiota amplicon sequence variants (ASVs) using beta-binomial regression and faecal SCFAs using linear regression. We adjusted models for confounders. RESULTS Of the 70 infants in our sample, 25 (36%) were delivered by CS. Compared with vaginal delivery, CS was associated with differential abundance of 14 infant bacterial ASVs at 3 months and 13 ASVs at 12 months (all FDR P < 0.05). Of note, CS infants had a higher abundance of the potential pathobionts Clostridium neonatale (P = 0.04) and Clostridium perfringens (P = 0.04) and a lower abundance of potentially beneficial Bifidobacterium and Bacteroides spp. (both P < 0.05) at 3 months. Other ASVs were differentially abundant at 12 months. Infants delivered by CS also had higher faecal butyrate concentration at 3 months (P < 0.005) but not at 12 months. CONCLUSIONS Caesarean section was associated with increased butyrate excretion, decreased Bifidobacterium and Bacteroides spp., and more colonisation of the infant gut by pathobionts at 3 months of age. CS was also associated with altered gut microbiota composition, but not faecal SCFAs, at 12 months. TWEETABLE ABSTRACT Caesarean section delivery was associated with increased butyrate excretion, decreased Bifidobacterium, and increased colonisation of the infant gut by pathobionts at 3 months of age.

Delivery mode and altered infant growth at 1 year of life in India. Pediatr Res 2021; 90:1251-1257. [PMID: 33654288 PMCID: PMC8671090 DOI: 10.1038/s41390-021-01417-6] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Revised: 01/30/2021] [Accepted: 02/01/2021] [Indexed: 12/31/2022]
Abstract
BACKGROUND Cesarean section (C-section) delivered infants are more likely to be colonized by opportunistic pathogens, resulting in altered growth. We examined whether C-section (elective/emergency) vs vaginal delivery was associated with altered weight and linear growth at 1 year of life. METHODS A total of 638 mother-infant pairs were included from MAASTHI cohort 2016-2019. Information on delivery mode was obtained from medical records. Based on WHO child growth standards, body mass index-forage z-score (BMI z) and length-for-age z-score (length z) were derived. We ran multivariable linear and Poisson regression models before and after multiple imputation. RESULTS The rate of C-section was 43.4% (26.5%: emergency, 16.9%: elective). Percentage of infant overweight was 14.9%. Compared to vaginal delivery, elective C-section was associated with β = 0.57 (95% CI 0.20, 0.95) higher BMI z. Also infants born by elective C-section had RR = 2.44 (95% CI 1.35, 4.41) higher risk of being overweight; no such association was found for emergency C-section. Also, elective C-section delivery was associated with reduced linear growth at 1 year after multiple imputation (β = -0.38, 95% CI -0.76, -0.01). CONCLUSIONS Elective C-section delivery might contribute to excess weight and also possibly reduced linear growth at 1 year of age in children from low- and middle-income countries. IMPACT Our study, in a low-income setting, suggests that elective, but not emergency, C-section is associated with excess infant BMI z at 1 year of age and elective C (C-section) was also associated with altered linear growth but only in multiple imputation analyses. Elective C-section was associated with a higher risk of being overweight at 1 year of age. Our results indicate that decreasing medically unnecessary elective C-section deliveries may help limit excess weight gain and stunted linear growth among infants.

Mode of birth and risk of infection-related hospitalisation in childhood: A population cohort study of 7.17 million births from 4 high-income countries. PLoS Med 2020; 17:e1003429. [PMID: 33211696 PMCID: PMC7676705 DOI: 10.1371/journal.pmed.1003429] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2020] [Accepted: 10/16/2020] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND The proportion of births via cesarean section (CS) varies worldwide and in many countries exceeds WHO-recommended rates. Long-term health outcomes for children born by CS are poorly understood, but limited data suggest that CS is associated with increased infection-related hospitalisation. We investigated the relationship between mode of birth and childhood infection-related hospitalisation in high-income countries with varying CS rates. METHODS AND FINDINGS We conducted a multicountry population-based cohort study of all recorded singleton live births from January 1, 1996 to December 31, 2015 using record-linked birth and hospitalisation data from Denmark, Scotland, England, and Australia (New South Wales and Western Australia). Birth years within the date range varied by site, but data were available from at least 2001 to 2010 for each site. Mode of birth was categorised as vaginal or CS (emergency/elective). Infection-related hospitalisations (overall and by clinical type) occurring after the birth-related discharge date were identified in children until 5 years of age by primary/secondary International Classification of Diseases, 10th Revision (ICD-10) diagnosis codes. Analysis used Cox regression models, adjusting for maternal factors, birth parameters, and socioeconomic status, with results pooled using meta-analysis. In total, 7,174,787 live recorded births were included. Of these, 1,681,966 (23%, range by jurisdiction 17%-29%) were by CS, of which 727,755 (43%, range 38%-57%) were elective. A total of 1,502,537 offspring (21%) had at least 1 infection-related hospitalisation. Compared to vaginally born children, risk of infection was greater among CS-born children (hazard ratio (HR) from random effects model, HR 1.10, 95% confidence interval (CI) 1.09-1.12, p < 0.001). The risk was higher following both elective (HR 1.13, 95% CI 1.12-1.13, p < 0.001) and emergency CS (HR 1.09, 95% CI 1.06-1.12, p < 0.001). Increased risks persisted to 5 years and were highest for respiratory, gastrointestinal, and viral infections. Findings were comparable in prespecified subanalyses of children born to mothers at low obstetric risk and unchanged in sensitivity analyses. Limitations include site-specific and longitudinal variations in clinical practice and in the definition and availability of some data. Data on postnatal factors were not available. CONCLUSIONS In this study, we observed a consistent association between birth by CS and infection-related hospitalisation in early childhood. Notwithstanding the limitations of observational data, the associations may reflect differences in early microbial exposure by mode of birth, which should be investigated by mechanistic studies. If our findings are confirmed, they could inform efforts to reduce elective CS rates that are not clinically indicated.

Abstract
In this study, we sought to ascertain a relationship between gestational age at birth and infectious morbidity of the offspring via population-based cohort analysis comparing the long-term incidence of infectious morbidity in infants born preterm and stratified by extremity of prematurity (extreme preterm birth: 24 + 0–27 + 6, very preterm birth: 28 + 0–31 + 6, moderate to late preterm birth: 32 + 0−36 + 6 weeks of gestation, and term deliveries). Infectious morbidity included hospitalizations involving a predefined set of International Classification of Diseases 9 (ICD9) codes, as recorded in hospital records. A Kaplan–Meier survival curve compared cumulative incidence of infectious-related morbidity. A Cox proportional hazards model controlled for confounders and time to event. The study included 220,594 patients: 125 (0.1%) extreme preterm births, 784 (0.4%) very preterm births, 13,323 (6.0%) moderate to late preterm births, and 206,362 term deliveries. Offspring born preterm had significantly more infection-related hospitalizations (18.4%, 19.8%, 14.9%, and 11.0% for the aforementioned stratification, respectively, p < 0.001). Multivariate analysis found being born very or late to moderate preterm was independently associated with long-term infectious morbidity (adjusted hazard ratio (aHR) 1.5, 95% confidence interval (CI) 1.27–1.77 and aHR 1.23, 95% CI 1.17–1.3, respectively, p < 0.001). A comparable risk of long-term infectious morbidity was found in the two groups of premature births prior to 32 weeks gestation. In our population, a cutoff from 32 weeks and below demarks a significant increase in the risk of long-term infectious morbidity of the offspring.

Abstract
PURPOSE Cesarean delivery (CD) has been recently suggested to be associated with offspring's long-term health implications. We aimed to investigate the association between delivery mode and long-term infectious morbidity of the offspring while employing sibling matched analysis to maximize confounder control. METHODS A retrospective population-based cohort study was performed, which included all sibling deliveries occurring between 1991 and 2014 at a regional tertiary medical center. Offsprings were followed up until the age of 18 years. The study included 13,516 individuals (6758 sibling pairs): the first born was via vaginal delivery and the second via CD. Each siblings pair was considered a matched set, with the aim to perform a within-family analysis. A Kaplan-Meier survival curve was used to compare the cumulative infectious morbidity incidence and a multivariable Cox survival hazards regression model to control for confounders. RESULTS Crude rates of total infectious hospitalizations were found to be significantly higher in the CD group (OR 1.25; 95% CI 1.12-1.40). Specifically, bronchiolitis (OR 2.02, 95% CI 1.56-2.63), otitis (OR 1.52, 95% CI 1.21-1.9), and gastroenteritis (OR 1.41, 95% CI 1.05-1.9) were all found to be significantly more common in the CD group. The survival curve demonstrated significantly higher cumulative infection-related hospitalization rates in the CD group (log-rank p < 0.001). The Cox model, adjusted for several confounders, confirmed the significant association between CD and offspring's infection-related morbidity (adjusted HR 1.25; 95% CI 1.02-1.53). CONCLUSION CD appears to be independently associated with later offspring infection-related morbidity, even while rigorously adjusting for confounders.

Abstract
OBJECTIVE To evaluate the impact of cesarean delivery (CD) on offspring risk for long-term cardiovascular morbidity. STUDY DESIGN A population-based cohort analysis was performed, including all singleton term deliveries occurring between 1991 and 2014 at a single tertiary medical center. A comparison was performed between children delivered via CD and those delivered vaginally. Fetuses with cardiac or other congenital malformations were excluded, as were cases of urgent CD and pregnancies involving preeclampsia, gestational diabetes, placenta previa, labor induction, fetal growth restriction, preterm PROM, and instrumental deliveries. Hospitalizations of the offspring up to 18 years of age involving cardiovascular morbidity were compared between the two study groups. A Kaplan-Meier survival curve compared cumulative cardiovascular morbidity incidence and a Cox regression model controlled for confounders. RESULTS Of the 132,054 term deliveries who met the inclusion criteria; 8.9% were CDs (n = 11,746) and 91.1% (n = 120,308) were vaginal deliveries. Cardiovascular hospitalization incidence per 1000 person follow up years was 0.742 in the CD group and 0.054 in the comparison group (HR = 1.3, 95%CI 1.051-1.710, p = .018). The Kaplan-Meier survival curve demonstrated a significantly higher cumulative incidence of cardiovascular morbidity following CD (log rank p = .018). In the Cox proportional hazards model, CD was noted as an independent risk factor for offspring long-term pediatric cardiovascular morbidity (adjusted HR = 1.295, CI 1.005-1.668, p = .04) when controlling for maternal age, obesity, ethnicity, gestational age, newborn gender, low birthweight, maternal preexisting cardiovascular disease, and deliveries occurring after 2008. CONCLUSION Singletons delivered by CD at term have an increased risk of long-term cardiovascular morbidity.

Abstract
Since introduced, the Apgar score has remained the most widespread predictor for neonatal morbidity and mortality. We aimed to investigate the association between low 5-min Apgar score and long-term infectious pediatric morbidity. A population-based cohort analysis was performed comparing total and specific subtypes of infectious morbidity leading to hospitalization among term newborns with normal (≥ 7) and low (< 7) 5-min Apgar scores, born between 1999 and 2014 at a single tertiary regional hospital. Infectious morbidity included hospitalizations involving a pre-defined set of infection-related ICD-9 codes. A Kaplan-Meier survival curve was constructed to compare cumulative infectious morbidity incidence and a Cox proportional hazards model to adjust for confounders. The long-term analysis of 223,335 children (excluding perinatal death cases) yielded 585 (0.3%) infants with low 5-min Apgar scores. The rate of infection-related hospitalizations was 9.8% and 12.4% among newborns with normal and low 5-min Apgar scores, respectively (p = 0.06). Adjusting for maternal age, gestational age, hypertension, diabetes, cesarean delivery, and fertility treatments, the association proved to be statistically significant (adjusted HR = 1.28; 95% CI 1.01-1.61).Conclusion: Term infants with low 5-min Apgar scores may be at an increased risk for long-term pediatric infectious morbidity.What is Known:• Though not meant to be a prognostic tool for long-term morbidity, studies assessing the correlation between low Apgar score and long-term outcomes were and are being performed, reporting significant associations with many outcomes-such as cerebral palsy (CP), ophthalmic disorders, GI disorders, and several types of malignancies.• Yet, an association between low Apgar scores and future health remains a matter of controversy.What is New:• Our work shows that a low 5-min Apgar score is independently associated with long-term pediatric infection-related hospitalizations among term singleton newborns.

Abstract
OBJECTIVE We evaluated the association between maternal preeclampsia and long-term infectious morbidity of the offspring. STUDY DESIGN A retrospective cohort analysis was performed, evaluating risk of long-term infectious morbidity in children born to women with and without preeclampsia between the years 1991-2014. Infectious morbidity included hospitalizations of offspring during childhood. Infants were followed until age 18 years or until hospitalization. Multiple gestations, newborns with congenital malformations and perinatal deaths were excluded. Cumulative incidence rates of infectious morbidity were compared. A Cox proportional hazards model was employed to control for various confounders including gestational age and cesarean delivery (CD). RESULTS During the study period 239,725 newborns were included: 96% (n = 230,217) without preeclampsia, 3% (n = 7280) with mild preeclampsia and 0.9% (n = 2228) with severe preeclampsia, defined mostly by evidence of maternal organ dysfunction. Hospitalization rate due to infectious morbidity was significantly higher for offspring to mothers with severe preeclampsia in comparison to those with no preeclampsia (13.1% vs 11%, P = 0.008), specifically respiratory and bacterial infections. The Kaplan-Meier survival curve demonstrated that offspring born to mothers with severe preeclampsia had a significantly higher cumulative incidence of hospitalization (Log-rank test P value = 0.026). However, while controlling for confounders in the Cox regression model, severe preeclampsia was not found as an independent risk factor (adjusted hazard ratio 0.95, 95% confidence interval 0.8-1.1, P = 0.36). CONCLUSION While severe preeclampsia is associated with higher risk for long-term infectious morbidity of the offspring, it seems that the association is due to prematurity and CD, but not the preeclampsia per-se.

Abstract
BACKGROUND Pregnancy with an Intrauterine device (IUD) is a risk factor for adverse pregnancy outcomes. The purpose of this study was to examine a possible association between presence of IUD during pregnancy and long-term incidence of infectious-related hospitalizations of the offspring. METHODS A population-based cohort analysis was performed including all singleton deliveries between 1991 and 2014 at a single tertiary hospital. Primary exposure was defined as delivery of an infant to a mother who conceived with an IUD, that was either removed or retained during pregnancy. Offspring of mothers who conceived without an IUD comprised the comparison group. The main outcome evaluated was infectious-related hospitalizations of the offspring up to the age of 18 years. RESULTS The number of deliveries that met the inclusion criteria was 227,431, of which 209 were to mothers who conceived with an IUD that was removed and 52 were to mothers who retained their device. Long-term incidence of infections-related hospitalizations was compared between the groups (12.5% in the retained IUD, 12.9% in the removed IUD and 11.2% in the No-IUD group, P = 0.638). A Kaplan-Meier survival curve did not demonstrate a significantly higher cumulative incidence of infectious-related hospitalizations in offspring of women who conceived with an IUD (log-rank P = 0.340). In a Cox regression model, while controlling for confounders such as maternal age and preterm birth, conceiving with an IUD was not found to be independently associated with long-term incidence of infectious-related hospitalizations of the offspring. CONCLUSION Offspring of women conceiving with an IUD are not at increased risk for long-term incidence of infectious-related hospitalizations.

BACKGROUND Gut microbiome influences cutaneous diseases including atopic dermatitis. Possible impact of intrauterine exposure to meconium on the occurrence of dermatitis and skin rash was proposed. OBJECTIVE We investigated the possible influence of intrauterine exposure to meconium-stained amniotic fluid (MSAF) on the occurrence of dermatitis and skin rash-related hospitalizations throughout childhood. METHODS Singleton deliveries occurring between 1991 and 2014 at a single medical centre were divided into two study groups based on presence or lack of MSAF during delivery. Population-based cohort analysis, Kaplan-Meier survival analysis and Cox proportional hazards model were used to study the association between MSAF and cutaneous morbidity-related hospitalizations. RESULTS A lower rate of the total dermatitis or skin eruption-related hospitalization was documented in the MSAF-exposed group; 0.78 per 1000-person years (0.9%, n = 312), as compared to 0.98 per 1000-person years in the unexposed group (1.0%, n = 1992) with a hazard ratio of 0.86 (95% CI 0.76-0.96, P = 0.011). The survival curve showed lower cumulative hospitalization rate in the MSAF-exposed group as compared to the unexposed group (log rank P = 0.01). The Cox analysis, controlled for confounders, demonstrated MSAF exposure to be an independent protective factor for dermatitis and skin rash-related hospitalizations during childhood (adjusted HR 0.878 (95% CI 0.779-0.990, P = 0.034). CONCLUSION Fetal exposure to MSAF appears to be an independent protective factor for dermatitis and skin rash-related hospitalizations in the offspring throughout childhood and adolescence.

Abstract
Obesity is a leading cause of morbidity world-wide. Maternal obesity is associated with adverse perinatal outcomes. Furthermore, Obesity has been associated with increased susceptibility to infections. The purpose of this study was to evaluate long-term pediatric infectious morbidity of children born to obese mothers. This population-based cohort analysis compared deliveries of obese (maternal pre-pregnancy BMI ≥ 30 kg/m2) and non-obese patients at a single tertiary medical center. Hospitalizations of the offspring up to the age of 18 years involving infectious morbidities were evaluated according to a predefined set of ICD-9 codes. A Kaplan–Meier survival curve was used to compare cumulative hospitalization incidence between the groups and Cox proportional hazards model was used to control for possible confounders. 249,840 deliveries were included. Of them, 3399 were children of obese mothers. Hospitalizations involving infectious morbidity were significantly more common in children born to obese mothers compared with non-obese patients (12.5% vs. 11.0%, p < 0.01). The Kaplan–Meier survival curve demonstrated a significantly higher cumulative incidence of infectious-related hospitalizations in the obese group (log rank p = 0.03). Using the Cox regression model, maternal obesity was found to be an independent risk factor for long-term infectious morbidity of the offspring (adjusted HR = 1.125, 95% CI 1.021–1.238, p = 0.017).

Abstract
BACKGROUND Urinary tract infection (UTI) is a common bacterial infection in pregnant women and is associated with adverse perinatal outcomes. We sought to investigate the long-term infectious outcomes of children to mothers who were diagnosed with UTI during their pregnancy. METHODS A population-based cohort analysis was conducted at a single tertiary medical center. The study included all singleton deliveries between the years 1991-2014, comparing offspring born to mothers diagnosed with UTI during their pregnancy with those born to non-exposed mothers. Infectious-related hospitalizations of the offspring up to the age of 18 years were assessed according to a predefined set of ICD-9 codes. A Kaplan-Meier survival curve was conducted to compare cumulative hospitalization incidence between the groups. A Cox regression model was used to adjust for confounders. RESULTS During the study period, 243,725 deliveries met the inclusion criteria. Of them, 8034 (3.3%) were exposed to maternal UTI during pregnancy. Infectious-related hospitalizations were significantly prevalent in offspring to exposed mothers (12.3% vs. 11.0%, OR = 1.125, 95% CI 1.051-1.204, Kaplan-Meier log rank p < 0.001). In the Cox regression model, while controlling for clinically relevant confounders, maternal UTI (adjuster HR = 1.240), as well as preterm delivery (adjusted HR = 1.385) and cesarean delivery (adjusted HR = 1.198) were noted as independent risk factors for long-term infectious morbidity of the offspring. CONCLUSIONS Maternal UTI in pregnancy may influence offspring susceptibility to pediatric infections, as it was found to be an independent risk factor for long-term infectious morbidity of the offspring.

Meconium-stained amniotic fluid exposure is associated with a lower incidence of offspring long-term infectious morbidity. Am J Reprod Immunol 2019; 81:e13108. [PMID: 30817041 DOI: 10.1111/aji.13108] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2019] [Revised: 01/27/2019] [Accepted: 02/11/2019] [Indexed: 01/05/2023] Open
Abstract
OBJECTIVE Meconium-stained amniotic fluid (MSAF) is a well-established risk factor for immediate adverse neonatal outcomes and was recently suggested to be associated with microbial invasion of the amniotic cavity. We aimed to determine whether MSAF exposure during labor carries a longer lasting impact on pediatric infectious morbidity. STUDY DESIGN A population-based cohort analysis was performed including all singleton deliveries occurring between 1991 and 2014 at a single tertiary medical center. Exposure was defined as the presence of MSAF during labor. Hospitalizations of the offspring up to the age of 18 years involving infectious diseases were evaluated. A Kaplan-Meier survival curve was used to compare cumulative morbidity and a Cox regression model to control for confounders. RESULTS During the study period, 243 725 deliveries met the inclusion criteria. Of them, 35 897 (14.7%) involved MSAF. Rate of infectious-related hospitalizations of the offspring was significantly lower in children exposed to MSAF as compared with the unexposed group (10.8% vs 11.1%, P < 0.05). Specifically, hospitalizations involving respiratory infections were significantly less common among the MSAF group (5.1% vs 5.6%, P < 0.001). The survival curve demonstrated significantly lower cumulative total infectious morbidity rates in the MSAF-exposed group (log rank P < 0.001). In the Cox model, controlled for maternal age, diabetes, hypertension, mode of delivery, and gestational age, exposed children exhibited lower rates of long-term childhood infectious morbidity (adjusted HR 0.96, 95% CI 0.92-0.99, P < 0.001). CONCLUSION Fetal exposure to MSAF during labor and delivery appears to be associated with lower rates of long-term infectious-related hospitalizations in the offspring.
