Development and Validation of a Novel Placental DNA Methylation Biomarker of Maternal Smoking during Pregnancy in the ECHO Program.

Maternal cigarette smoking during pregnancy (MSDP) is associated with numerous adverse health outcomes in infants and children with potential lifelong consequences. Negative effects of MSDP on placental DNA methylation (DNAm), placental structure, and function are well established. Our aim was to develop biomarkers of MSDP using DNAm measured in placentas (), collected as part of the Vitamin C to Decrease the Effects of Smoking in Pregnancy on Infant Lung Function double-blind, placebo-controlled randomized clinical trial conducted between 2012 and 2016. We also aimed to develop a digital polymerase chain reaction (PCR) assay for the top ranking cytosine-guanine dinucleotide (CpG) so that large numbers of samples can be screened for exposure at low cost. We compared the ability of four machine learning methods [logistic least absolute shrinkage and selection operator (LASSO) regression, logistic elastic net regression, random forest, and gradient boosting machine] to classify MSDP based on placental DNAm signatures. We developed separate models using the complete EPIC array dataset and on the subset of probes also found on the 450K array so that models exist for both platforms. For comparison, we developed a model using CpGs previously associated with MSDP in placenta. For each final model, we used model coefficients and normalized beta values to calculate placental smoking index (PSI) scores for each sample. Final models were validated in two external datasets: the Extremely Low Gestational Age Newborn observational study, ; and the Rhode Island Children's Health Study, . Logistic LASSO regression demonstrated the highest performance in cross-validation testing with the lowest number of input CpGs. Accuracy was greatest in external datasets when using models developed for the same platform. PSI scores in smokers only () were moderately correlated with maternal plasma cotinine levels. One CpG (cg27402634), with the largest coefficient in two models, was measured accurately by digital PCR compared with measurement by EPIC array (). To our knowledge, we have developed the first placental DNAm-based biomarkers of MSDP with broad utility to studies of prenatal disease origins. https://doi.org/10.1289/EHP13838.

Barriers, facilitators, and other factors associated with health behaviors in childhood, adolescent, and young adult cancer survivors: A systematic review.

Healthy behaviors are paramount in preventing long-term adverse health outcomes in childhood, adolescent, and young adult (CAYA) cancer survivors. We systematically reviewed and synthesized existing literature on barriers, facilitators, and other factors associated with health behaviors in this population. MEDLINE and PsycInfo were searched for qualitative and quantitative studies including survivors aged 16-50 years at study, a cancer diagnosis ≤25 years and ≥2 years post diagnosis. Health behaviors included physical activity, smoking, diet, alcohol consumption, sun exposure, and a combination of these behaviors (defined as health behaviors in general). Barriers, facilitators, and other factors reported in ≥2 two studies were considered relevant. Out of 4529 studies, 27 were included (n = 31,905 participants). Physical activity was the most frequently examined behavior (n = 12 studies), followed by smoking (n = 7), diet (n = 7), alcohol (n = 4), sun exposure (n = 4), and health behavior in general (n = 4). Relevant barriers to physical activity were fatigue, lack of motivation, time constraints, and current smoking. Relevant facilitators were perceived health benefits and motivation. Influence of the social environment and poor mental health were associated with more smoking, while increased energy was associated with less smoking. No relevant barriers and facilitators were identified for diet, alcohol consumption, and sun exposure. Barriers to healthy behavior in general were unmet information needs and time constraints whereas lifestyle advice, information, and discussions with a healthcare professional facilitated healthy behavior in general. Concerning other factors, women were more likely to be physically inactive, but less likely to drink alcohol and more likely to comply with sun protection recommendations than men. Higher education was associated with more physical activity, and lower education with more smoking. This knowledge can be used as a starting point to develop health behavior interventions, inform lifestyle coaches, and increase awareness among healthcare providers regarding which survivors are most at risk of unhealthy behaviors.

Socioeconomic and residence-based inequalities in adolescent fertility in 39 African countries

IntroductionDespite the advancement in sexual and reproductive healthcare services and several public health measures aimed at controlling fertility rates, countries in sub-Saharan Africa (SSA) still experience higher adolescent fertility rates than other low-and middle-income countries. This study examined the disparities in adolescent fertility in 39 countries in SSA, focusing on socioeconomic and residence-based dimensions.MethodsThis study involved a secondary analysis of data obtained from 39 recent Demographic and Health Surveys conducted in SSA. The measures of difference (D), ratio (R), population attributable fraction (PAF), and population attributable risk (PAR) were estimated using the Health Equity Assessment Tool (HEAT) software version 3.1 developed by the World Health Organization. The measures: D, R, PAF, and PAR were used to examine the inequalities in adolescent fertility across the socioeconomic and residence-based dimensions.ResultsOut of the 39 countries included in the study, Guinea (D=27.70), Niger (D=27.50), Nigeria (D=23.90), and Côte d’Ivoire (D=23.60) exhibited the most significant residence-based inequalities in the rate of adolescent fertility, with the higher rate observed among adolescents in rural areas. Rwanda was the sole country that showed a slight inclination towards rural inequality in terms of the rate of adolescent fertility, with a value of D = -0.80. The burden of adolescent fertility was disproportionately higher among young women with low economic status across all the countries, exacerbating wealth-based inequities. The countries with the largest absolute discrepancies were Nigeria (D=44.70), Madagascar (D=41.10), Guinea (D=41.00), and Cameroon (D=40.20). We found significant disparities in educational attainment contributing to unequal inequalities in adolescent fertility, particularly among young women who lack access to formal education. Countries such as Madagascar (D=59.50), Chad (D=55.30), Cameroon (D=54.60), and Zimbabwe (D=50.30) had the most significant absolute disparities.ConclusionThis study revealed that young women residing in rural areas, those in households with low economic status and those with limited educational opportunities experience a disproportionately high burden of adolescent fertility across the 39 countries in SSA. The current findings offer valuable information to governmental entities at all levels regarding the need to ensure the provision of equitable, accessible, and dependable sexual and reproductive health services to the populace, particularly for young women. Therefore, the various stakeholders need to enhance the effectiveness of health policies and legislation pertaining to adolescent women living in rural areas, those from economically disadvantaged households, and those with limited or no access to formal education. Such interventions could potentially reduce adolescent fertility rates and mitigate the adverse maternal and child outcomes associated with high adolescent fertility in SSA.

Clinical validation and accuracy assessment of the Capsule Endoscopy-Crohn's Disease index (CE-CD).

To compare the recently proposed Capsule Endoscopy-Crohn's Disease index (CE-CD) to pre-existing capsule endoscopy (CE) scores, to measure its precision and accuracy to predict adverse clinical outcomes in children with Crohn's disease (CD). Children with CD who underwent CE at diagnosis and had, at least, 1-year follow-up postprocedure were selected. Capsule study was viewed and the different indices were independently scored by two trained paediatric gastroenterologists. The relationship between pre-existing scores and CE-CD was assessed by linear regression analysis. Clinical outcomes prediction assessment was based on receiver operating characteristics curves, survival analysis and Cox regression. Finally, interobserver agreement was measured. Fifty-nine patients were finally included. CE-CD showed a strong positive correlation with the Lewis score (ρ = 0.947) and the Capsule Endoscopy Crohn's Disease Activity Index (CECDAI) (ρ = 0.982). Both CE-CD and CECDAI were significant predictors of treatment escalation (hazard ratio 1.07 and 1.09, respectively, with both p-values < 0.01). However, no score predicted risk of hospital admission, surgeryor clinical/endoscopic relapse. The presence of moderate-to-severe small bowel (SB) inflammation, defined as a score of ≥9 on CE-CD, provided a hazard ratio of treatment escalation of 2.6 (95% confidence interval: 1.3-5.3). This cut-off provided the optimal sensitivity/specificity pair: 48.4%/89.3%. No interobserver misclassification among inflammation categories given by CE-CD were observed (kappa 100%). CE-CD is a useful tool to document SB inflammation in children with CD. It correlates strongly with classical scores, can better predict need for treatment escalation and shows good interobserver agreement.

Multi-repeat sequences identification using genome mining techniques for developing highly sensitive molecular diagnostic assay for the detection of Chlamydia trachomatis.

Chlamydia trachomatis ( C. trachomatis) is a common sexually transmitted infection (STI). In 2019, the World Health Organization reported about 131 million infections. The majority of infected patients are asymptomatic with cases remaining undetected. It is likely that missed C. trachomatis infections contribute to preventable adverse health outcomes in women and children. Consequently, there is an urgent need of developing efficient diagnostic methods. In this study, genome-mining approaches to identify identical multi-repeat sequences (IMRS) distributed throughout the C. trachomatis genome were used to design a primer pair that would target regions in the genome. Genomic DNA was 10-fold serially diluted (100pg/μL to 1×10 -3pg/μL) and used as DNA template for PCR reactions. The gold standard PCR using 16S rRNA primers was also run as a comparative test, and products were resolved on agarose gel. The novel assay, C. trachomatis IMRS-PCR, had an analytical sensitivity of 4.31 pg/µL, representing better sensitivity compared with 16S rRNA PCR (9.5 fg/µL). Our experimental data demonstrate the successful development of lateral flow and isothermal assays for detecting C. trachomatis DNA with potential use in field settings. There is a potential to implement this concept in miniaturized, isothermal, microfluidic platforms, and laboratory-on-a-chip diagnostic devices for reliable point-of-care testing.

Short birth interval in the Asia-Pacific region: A systematic review and meta-analysis.

Short birth interval is associated with an increased risk of adverse health outcomes for mothers and children. Despite this, there is a lack of comprehensive evidence on short birth interval in the Asia-Pacific region. Thus, this study aimed to synthesise evidence related to the definition, classification, prevalence, and predictors of short birth interval in the Asia-Pacific region. Five databases (MEDLINE, Scopus, Cumulative Index to Nursing and Allied Health Literature, Maternity and Infant Care, and Web of Science) were searched for studies published between September 2000 and May 2023 (the last search was conducted for all databases in May 2023). We included original studies published in English that reported on short birth interval in the Asia-Pacific region. Studies that combined birth interval with birth order, used multi-country data and were published as conference abstracts and commentaries were excluded. Three independent reviewers screened the articles for relevancy, and two reviewers performed the data extraction and quality assessment. The risk of bias was assessed using the Joanna Briggs Institute critical appraisal tool. The findings were both qualitatively and quantitatively synthesised and presented. A total of 140 studies met the inclusion criteria for this review. About 58% (n = 82) of the studies defined short birth interval, while 42% (n = 58) did not. Out of 82 studies, nearly half (n = 39) measured a birth-to-birth interval, 37 studies measured a birth-to-pregnancy, four measured a pregnancy-to-pregnancy, and two studies measured a pregnancy loss-to-conception. Approximately 39% (n = 55) and 6% (n = 8) of studies classified short birth intervals as <24 months and <33 months, respectively. Most of the included studies were cross-sectional, and about two-thirds had either medium or high risk of bias. The pooled prevalence of short birth interval was 33.8% (95% confidence interval (CI) = 23.0-44.6, I2 = 99.9%, P < 0.01) among the studies that used the World Health Organization definition. This review's findings highlighted significant variations in the definition, measurement, classification, and reported prevalence of short birth interval across the included studies. Future research is needed to harmonise the definition and classification of short birth interval to ensure consistency and comparability across studies and facilitate the development of targeted interventions and policies.

Placental DNA methylation signatures of prenatal air pollution exposure and potential effects on birth outcomes: an analysis of three prospective cohorts.

Pregnancy air pollution exposure (PAPE) has been linked to a wide range of adverse birth and childhood outcomes, but there is a paucity of data on its influence on the placental epigenome, which can regulate the programming of physiological functions and affect child development. This study aimed to investigate the association between prenatal air pollutant exposure concentrations and changes in placental DNA methylation patterns, and to explore the potential windows of susceptibility and sex-specific alterations. This multi-site study used three prospective population-based mother-child cohorts: EDEN, PELAGIE, and SEPAGES, originating from four French geographical regions (Nancy, Poitiers, Brittany, and Grenoble). Pregnant women were included between 2003 and 2006 for EDEN and PELAGIE, and between 2014 and 2017 for SEPAGES. The main eligibility criteria were: being older than 18 years, having a singleton pregnancy, and living and planning to deliver in one of the maternity clinics in one of the study areas. A total of 1539 mother-child pairs were analysed, measuring placental DNA methylation using Illumina BeadChips. We used validated spatiotemporally resolved models to estimate PM2·5, PM10, and NO2 exposure over each trimester of pregnancy at the maternal residential address. We conducted a pooled adjusted epigenome-wide association study to identify differentially methylated 5'-C-phosphate-G-3' (CpG) sites and regions (assessed using the Infinium HumanMethylationEPIC BeadChip array, n=871), including sex-specific and sex-linked alterations, and independently validated our results (assessed using the Infinium HumanMethylation450 BeadChip array, n=668). We identified four CpGs and 28 regions associated with PAPE in the total population, 469 CpGs and 87 regions in male infants, and 150 CpGs and 66 regions in female infants. We validated 35% of the CpGs available. More than 30% of the identified CpGs were related to one (or more) birth outcome and most significant alterations were enriched for neural development, immunity, and metabolism related genes. The 28 regions identified for both sexes overlapped with imprinted genes (four genes), and were associated with neurodevelopment (nine genes), immune system (seven genes), and metabolism (five genes). Most associations were observed for the third trimester for female infants (134 of 150 CpGs), and throughout pregnancy (281 of 469 CpGs) and the first trimester (237 of 469 CpGs) for male infants. These findings highlight the molecular pathways through which PAPE might affect child health in a widespread and sex-specific manner, identifying the genes involved in the major physiological functions of a developing child. Further studies are needed to elucidate whether these epigenetic changes persist and affect health later in life.

Systemic Inflammatory Response Index (SIRI) as a Predictive Marker for Adverse Outcomes in Children with New-Onset Type 1 Diabetes Mellitus.

(1) Background: Although most cases of new-onset type 1 diabetes mellitus (T1DM) are managed without serious events, life-threatening complications do arise in a subset of patients. Our objective was to assess the correlation between elevated SIRI values and adverse events related to the onset of T1DM. (2) Methods: This retrospective study, spanning ten years, included 187 patients with new-onset T1DM divided into three groups based on SIRI tertiles. The primary outcome was the occurrence of acute complications during hospital admission, while the secondary outcome was prolonged Intensive Care Unit (ICU) admission. (3) Results: Patients with high SIRI values were more likely to experience higher disease activity, leading to longer ICU admission times and more frequent complications. Multivariate logistic regression analysis revealed that the SIRI was independently associated with acute complications (p = 0.003) and prolonged ICU length of stay (p = 0.003). Furthermore, receiver operating characteristic analysis demonstrated the SIRI's superior predictive accuracy compared to venous pH (AUC = 0.837 and AUC = 0.811, respectively) and to the individual component cell lineages of the SIRI. (4) Conclusions: These findings emphasize the potential utility of the SIRI as a prognostic marker in identifying patients at increased risk during T1DM hospital admissions.

Maternal depression, parenting, and child psychological outcomes in the context of maternal pain.

Parental chronic pain is associated with adverse outcomes in children, but the mechanisms of transmission are largely untested. Mothers with chronic pain (N = 400, Mage = 40.3 years, 90.5% White) and their children (Mage = 10.33 years, 83.3% White, 50.2% female) were recruited in 2016-2018 to test longitudinal pathways of risk transmission from maternal chronic pain to children's psychological symptoms, examining roles of parenting, maternal depression, and child distress tolerance. Maternal pain was associated with positive (β = .28) and pain-specific (β = .10) parenting behaviors. Maternal depression was associated with lower child distress tolerance (β = -.03), which was associated with greater child psychological symptoms (β = -.62). Parenting and maternal pain were not prospectively associated with child outcomes. When considering the dual-generational impacts of chronic pain, physical and psychological functioning should be examined.

Le miR-224-5p régulé sert de biomarqueur pour l'insuffisance hépatique aiguë pédiatrique et régule l'inflammation en modulant ZBTB20

Pediatric acute liver failure (PALF) is a severe liver dysfunction with complex pathological mechanisms and rapid development. MiRNAs have been identified as promising biomarkers for human disease screening and monitoring. This study focused on evaluating the clinical significance of miR-224-5p in PALF and revealing its potential molecular mechanism in regulating liver cell injury. This study enrolled 103 children with PALF and 55 healthy children without liver diseases. Serum miR-224-5p levels were compared between the two groups, and their clinical significance was estimated by analyzing the correlation with clinicopathological features and outcomes of PALF children. In vitro, a normal liver cell was treated with lipopolysaccharide (LPS), and cell growth and inflammation were assessed by CCK8 and ELISA assay. Upregulated miR-224-5p in PALF showed significance in screening PALF children from healthy children with the sensitivity and specificity of 78.64% and 84.47%, respectively. Increasing serum miR-224-5p in PALF children was closely associated with increasing prothrombin time, alanine transaminase, international normalized ratio, total bilirubin, ammonia, and aspartic transaminase and decreasing albumin of PALF children. MiR-224-5p was also identified as a risk factor for adverse outcomes in children with PALF. In LPS-treated liver cells, miR-224-5p could negatively regulate ZBTB20, and silencing miR-224-5p could alleviate the inhibited cell growth and promoted inflammation by LPS, which was reversed by ZBTB20 knockdown. Increasing miR-224-5p distinguished PALF children, predict severe disease development and risk of adverse prognosis. miR-224-5p also reguled LPS-induced liver cell injury via negatively regulating ZBTB20.

Paternal use of selective serotonin reuptake inhibitors and adverse health outcomes: A nationwide cohort study on 13,547 exposed children.

The use of selective serotonin reuptake inhibitors (SSRIs) has increased over time. Several studies indicate that paternal use of medication may adversely affect the developing fetus. Only a few studies have investigated the association between preconceptional paternal exposure to SSRIs and the risks of adverse health outcomes in children. This study aimed to assess adverse birth outcomes and adverse early life events in children fathered by men using SSRIs prior to conception. All live-born singleton children born in Denmark from 1997 until 2019 and their parents were included. The exposed cohort comprised all children fathered by men using SSRIs 3 months prior to conception and the unexposed cohort comprised all other children. We estimated the odds ratios for adverse birth outcomes: small for gestational age (SGA), preterm birth, low Apgar score, and major congenital malformations. Furthermore, we estimated the hazard ratios for adverse early life events of infections and hospitalizations within 1 year from birth. We also examined adverse birth outcomes and the adverse early life events according to SSRI subgroups. There was a statistically significantly increased odds ratio 1.15 (confidence interval, CI: 1.06-1.23) for preterm birth. No significant results were found for SGA, low Apgar score, and major congenital malformations. The adjusted hazard ratios for hospitalizations and infections were 1.06 (CI: 1.02-1.11) and 1.02 (CI: 0.97-1.07), respectively. There was a statistically significantly increased odds ratio for preterm birth with respect to the SSRI subgroups citalopram and escitalopram, and for hospitalizations with respect to citalopram. Although the risks of certain adverse birth and adverse early life outcomes were statistically significantly increased, the ratios were small and may have limited clinical importance. Paternal use of SSRI was in general safe in the preconceptual period.

Prenatal maternal negative life events associated with child emotional and behavioral problems in the French EDEN cohort

IntroductionPrenatal negative life events (NLEs) have been linked to adverse health outcomes in children. However, few studies examine this relationship during late childhood using trajectory analyses. Additionally, the impact of specific NLEs domains on child development remains unclear. This study aims to longitudinally explore the association between NLEs (cumulative score and specific NLEs domains) and child outcomes from birth to late childhood. Methods1135 mother-child pairs from the French EDEN cohort were followed from 24 to 28 weeks of pregnancy up to 11 years of age. Maternal self-reports of prenatal NLEs were collected immediately after birth, then analyzed as a cumulative score and by NLEs domain. Children's emotional and behavioral symptoms were assessed at 4 timepoints through the Strengths and Difficulties Questionnaire. ResultsChildren of mothers exposed to ≥3 NLEs were more likely to follow trajectories of high levels of peer relationship problems (aOR [95 % CI] = 5.69 [1.74–18.69]), emotional symptoms (aOR [95 % CI] = 3.05 [1.08–8.63]), and conduct problems (aOR [95 %] = 3.53 [1.20–10.42]). Among the domains of NLEs, only events related to housing, finance, and living conditions were significantly associated with high emotional and behavioral difficulties trajectories (aOR [95%CI] = 2.71[1.26–5.81]). LimitationsPotential attrition bias due to a higher dropout rate for children experiencing early indications of emotional and behavioral difficulties. ConclusionFindings support the relationship between prenatal NLEs and child outcomes, underscoring the importance of assessing prenatal stressors across life domains to identify mothers who might be in need of support.

"Association between perinatal mood disorders of parents and child health outcomes".

Perinatal mood disorders affect both parents, impacting their children negatively. Little is known on the association between parental perinatal mood disorders and pediatric outcomes in Japan considering relevant covariates. Our objective was to investigate the association between paternal and maternal perinatal mood disorders and adverse physical and psychological child outcomes by the age of 36 months, adjusting for covariates such as the child's sex, age of parent at child's birth, perinatal mood disorders of the other parent, and perinatal antidepressant use. We identified parents in the JMDC Claims Database in Japan from 2012 to 2020. Perinatal mood disorders were defined using International Classification of Diseases, 10th codes for mood disorders during the perinatal period combined with psychiatric treatment codes. We evaluated the association between parental perinatal mood disorders and pediatric adverse outcomes by the age of 36 months using Cox proportional hazard models adjusted for the covariates. Of the 116,423 father-mother-child triads, 2.8% of fathers and 2.3% of mothers had perinatal mood disorders. Paternal perinatal mood disorders were not significantly associated with adverse child outcomes. After adjusting for paternal perinatal mood disorders and antidepressant use, maternal perinatal mood disorders were associated with delayed motor development, language development disorders, autism spectrum disorders, and behavioral and emotional disorders (adjusted hazard ratio [95% confidence interval]: 1.65 [1.01-2.69], 2.26 [1.36-3.75], 4.16 [2.64-6.55], and 6.12 [1.35-27.81], respectively). Paternal perinatal mood disorders were not associated with adverse child outcomes in this population. Maternal perinatal mood disorders were associated with multiple child outcomes.

Association Between Cord Blood Placental Growth Factor Level, Fetal Doppler Parameters and Neonatal Growth Measures

Background: Placental growth factor (PlGF) contributes to fetoplacental circulatory system development, whichever revealed to have an effect on the fetal size and growth. Objectives: To explore the inference between umbilical cord blood [fetal] PlGF, fetal doppler parameters, gestational age and neonatal growth parameters particularly birth weight, birth length, head circumference and mid arm circumference. Research protocol: This cross-sectional investigation was implemented on 50 pregnant women in their third trimester, aged 18-35years and their full term newborns. Full history taking, gestational age, general and obstetric examination and ultrasound investigation, fetal biometrics and doppler ultrasound were carried out. Umbilical cord blood PlGF was quantified using ELISA. All the enrolled neonates were submitted to full clinical examination by pediatrician and their anthropometric parameters were measured before breast feeding started. Results: Umbilical artery pulsatility index (UAPI) revealed significant negative correlation with neonatal weight and PlGF level. Meanwhile, gestational age (GA) showed significant positive correlation with the neonatal anthropometric parameters including mid arm circumference (MAC), head circumference, weight, length, weight Z score, length Z score, head Z score weight to length (W/L) and weight to length Z score (W/L Z Score). Also, significant positive correlation between PlGF and gestational age as well as the neonatal anthropometric measurements was registered except head Z Score. Multiple linear regression analysis for PlGF with UA PI and neonatal weight indicated that UAPI and neonatal weight were significant predictors for fetal PlGF. Conclusions: The current data illuminate the effect of fetal placental growth factor on neonatal adverse growth pattern. Additionally, fetal placental growth factor with fetal doppler parameters could be a promising predictive biomarkers to intervene neonates at risk for adverse childhood outcomes.

Socioeconomic Influences on Outcomes Following Congenital Heart Disease Surgery.

Associations between social determinants of health (SDOH) and adverse outcomes for children with congenital heart disease (CHD) are starting to be recognized; however, such links remain understudied. We examined the relationship between community-level material deprivation on mortality, readmission, and length of stay (LOS) for children undergoing surgery for CHD. We performed a retrospective cohort study of patients who underwent cardiac surgery at our institution from 2015 to 2018. A community-level deprivation index (DI), a marker of community material deprivation, was generated to contextualize the lived experience of children with CHD. Generalized mixed-effects models were used to assess links between the DI and outcomes of mortality, readmission, and LOS following cardiac surgery. The DI and components were scaled to provide mean differences for a one standard deviation (SD) increase in deprivation. We identified 1,187 unique patients with surgical admissions. The median LOS was 11days, with an overall mortality rate of 4.6% and readmission rate of 7.6%. The DI ranged from 0.08 to 0.85 with a mean of 0.37 (SD 0.12). The DI was associated with increased LOS for patients with more complex heart disease (STAT 3, 4, and 5), which persisted after adjusting for factors that could prolong LOS (all p < 0.05). The DI approached but did not meet a significant association with mortality (p = 0.0528); it was not associated with readmission (p = 0.36). Community-level deprivation is associated with increased LOS for patients undergoing cardiac surgery. Future work to identify the specific health-related social needs contributing to LOS and identify targets for intervention is needed.

Reversible Cerebral Vasoconstriction Syndrome in Children and Adolescents: A Case Series and Literature Review

Reversible cerebral vasoconstriction syndrome (RCVS) is a clinical radiographic phenomenon characterized by thunderclap headaches and transient vasoconstriction of cerebral vessels, which typically resolve within 3 months of symptom onset. Although RCVS has been extensively studied in adults, research on this condition in pediatric populations is limited, likely due to its perceived rarity. This comprehensive review aims to bridge the knowledge gap by examining the clinical presentation, diagnostic methods, treatment strategies, and prognostic outcomes of pediatric RCVS cases, including two case reports contributed by the authors. This study demonstrates an inconclusive sex distribution of RCVS in children, attributed to the scarcity of comprehensive studies of this demographic. Additionally, we identified several predictors of adverse neurological outcomes in children with RCVS, including motor deficits, aphasia, hypertension, and renal disease. This study offers a thorough overview of RCVS in the pediatric population, providing valuable insights to inform future research in this area.

Socio-economic disadvantage and utilisation of labour epidural analgesia in Scotland: a population-based study†.

Socio-economic deprivation is associated with adverse maternal and childhood outcomes. Epidural analgesia, the gold standard for labour analgesia, may improve maternal well-being. We assessed the association of socio-economic status with utilisation of epidural analgesia and whether this differed when epidural analgesia was advisable for maternal safety. This was a population-based study of NHS data for all women in labour in Scotland between 1 January 2007 and 23 October 2020, excluding elective caesarean sections. Socio-economic status deciles were defined using the Scottish Index of Multiple Deprivation. Medical conditions for which epidural analgesia is advisable for maternal safety (medical indications) and contraindications were defined according to national guidelines. Of 593,230 patients in labour, 131,521 (22.2%) received epidural analgesia. Those from the most deprived areas were 16% less likely to receive epidural analgesia than the most affluent (relative risk 0.84 [95%CI 0.82-0.85]), with the inter-decile mean change in receiving epidural analgesia estimated at -2% ([95%CI -2.2% to -1.7%]). Among the 21,219 deliveries with a documented medical indication for epidural analgesia, the socio-economic gradient persisted (relative risk 0.79 [95%CI 0.75-0.84], inter-decile mean change in receiving epidural analgesia -2.5% [95%CI -3.1% to -2.0%]). Women in the most deprived areas with a medical indication for epidural analgesia were still less likely (absolute risk 0.23 [95%CI 0.22-0.24]) to receive epidural analgesia than women from the most advantaged decile without a medical indication (absolute risk 0.25 [95%CI 0.24-0.25]). Socio-economic deprivation is associated with lower utilisation of epidural analgesia, even when epidural analgesia is advisable for maternal safety. Ensuring equitable access to an intervention that alleviates pain and potentially reduces adverse outcomes is crucial.

Hovering Is Not Helping: Relationships among Helicopter Parenting, Attachment, Academic Outcomes, and Mental Health in College Students

Helicopter parenting (or overparenting) refers to developmentally inappropriate or intrusive tactics to control a child’s behavior. Helicopter parents are usually trying to help their children, but their behavior has been associated with adverse academic, adjustment, and mental health outcomes in older children (i.e., adolescents, young adults), who should be developing more autonomy. The current study examined potential associations between helicopter parenting, attachment security, and academic and mental health outcomes in college students, hypothesizing that higher rates of helicopter parenting would be associated with more insecure attachment with parental figures and closest friends, poorer mental health (i.e., higher rates of depression and/or anxiety), and reduced academic motivation, performance, and self-efficacy. Our sample of 135 college students completed measures of anxiety, depression, and somatization, academic self-efficacy and motivation, perceptions of parental involvement, and dimensions of attachment in multiple relationships (i.e., mother, father, and closest friend). As expected, the bivariate and regression analyses revealed that higher levels of parental involvement (i.e., helicopter parenting) predicted significantly more insecure parental and peer attachment, greater internalizing, and lower effort regulation among college students.

Exposure to air pollution is associated with DNA methylation changes in sperm.

Exposure to air pollutants has been associated with adverse health outcomes in adults and children who were prenatally exposed. In addition to reducing exposure to air pollutants, it is important to identify their biologic targets in order to mitigate the health consequences of exposure. One molecular change associated with prenatal exposure to air pollutants is DNA methylation (DNAm), which has been associated with changes in placenta and cord blood tissues at birth. However, little is known about how air pollution exposure impacts the sperm epigenome, which could provide important insights into the mechanism of transmission to offspring. In the present study, we explored whether exposure to particulate matter less than 2.5 microns in diameter, particulate matter less than 10 microns in diameter, nitrogen dioxide (NO2), or ozone (O3) was associated with DNAm in sperm contributed by participants in the Early Autism Risk Longitudinal Investigation prospective pregnancy cohort. Air pollution exposure measurements were calculated as the average exposure for each pollutant measured within 4 weeks prior to the date of sample collection. Using array-based genome-scale methylation analyses, we identified 80, 96, 35, and 67 differentially methylated regions (DMRs) significantly associated with particulate matter less than 2.5 microns in diameter, particulate matter less than 10 microns in diameter, NO2, and O3, respectively. While no DMRs were associated with exposure to all four pollutants, we found that genes overlapping exposure-related DMRs had a shared enrichment for gene ontology biological processes related to neurodevelopment. Together, these data provide compelling support for the hypothesis that paternal exposure to air pollution impacts DNAm in sperm, particularly in regions implicated in neurodevelopment.

Hematological Indices for Identifying Adverse Outcomes in Children Admitted to Pediatric ICUs.

The pediatric ICU (PICU) is a specialized area where critically sick children are managed. The mortality rates in PICUs are higher in developing countries as compared to developed nations.Many of these deaths could be prevented if very sick children were identified soon after they arrived at the health facility. Hematological indices like platelet lymphocyte ratio (PLR) and neutrophil-lymphocyte ratio (NLR) have been frequently used in adults as indicators of mortality. However, their use in the pediatric population is limited due to a lack of validated reference intervals. The objective of the study is to assess the role of hematological indices in identifying adverse outcomes in terms of mortality in children admitted to the PICU. It is a prospective, observational study done at a tertiary care hospital. All children aged one year to 12 years admitted to the PICU were enrolled in the study. A sample for complete blood count was taken within one hour of admission to the PICU. Children who had received blood products in the last two months, those on chronic medications (>two weeks) that can affect bone marrow cellularity, and known cases ofhematological disorders such as megaloblastic anemia, hematological malignancies, immune thrombocytopenia, and aplastic anemia were excluded from the study.PLR, NLR, and platelets to mean platelet volume ratio (PLT/MPV) were determined and compared among the survivors and non-survivors. Out of 275 enrolled patients, 119 (43.3%) patients expired during the study period. While PLR had high sensitivity and NLR had high specificity (85.71% and 92.31%, respectively) for predicting mortality, none of these parameters had a good area under the curve (AUC) in our study.PLT/MPV of ≥32 had a sensitivity of 39.5% and a specificity of 56.41%for predicting mortality. Hematological parameters have been used across the world to predict ICU mortality. PLR and NLR are simple hematological biomarkers, easy to calculate, and cost-effective, and ratios are better than individual parameters. More studies and stratified samples are required to evaluate the role of hematological markers in identifying the risk of mortality in children admitted to PICUs.
