Obstetrical mode of delivery and behavioural outcomes in childhood and adolescence: findings from the Millennium Cohort Study

Purpose To examine the association between mode of delivery (in particular caesarean section) and behavioural outcomes in offspring at six time-points between age 3 and 17 years. Methods Similar to previous work examining the association between mode of delivery and behavioural outcomes in offspring at age 7, we used maternal-reported data from the Millennium Cohort Study. Data on mode of delivery were collected when children were 9 months and categorised as spontaneous vaginal delivery, assisted vaginal delivery, induced vaginal delivery, emergency caesarean section, planned caesarean section and caesarean section after induction of labor. Data on behavioural outcomes were collected at ages 3, 5, 7, 11, 14 and 17 years using the Strengths and Difficulties Questionnaire (SDQ). Crude and adjusted logistic regression examined mode of delivery–behavioural difficulties relationship, using validated SDQ cut-off points (total SDQ ≥ 17, emotional ≥ 5, conduct ≥ 4, hyperactivity ≥ 7, peer problems ≥ 4 and prosocial behaviour ≤ 4). Multilevel models with linear splines examined the association between mode of delivery and repeated measures of SDQ. Results There were 18,213 singleton mother–child pairs included at baseline, 13,600 at age 3; 13,831 at age 5; 12,687 at age 7; 11,055 at age 11; 10,745 at age 14 and 8839 at age 17. Adjusted logistic regression suggested few associations between mode of delivery and behavioural outcomes at ages 3, 5, 11, 14 and 17 years using validated SDQ cut-off points. After correction for multiple testing, only the protective association between planned caesarean section-Conduct difficulties at age 5 years (OR 0.63, 95% CI 0.46, 0.85) and positive association between caesarean section after induction-Emotional difficulties at age 11 years (OR 1.57, 95% CI 1.19, 2.07) remained statistically significant. Multilevel modelling suggested mean SDQ scores were similar in each mode of delivery group at each time point. Conclusions Results of this study indicate that mode of delivery is unlikely to have a major impact on behavioural outcomes.

Oxygen Saturation in Neonate after Birth

Background: Oxygen saturation measures the quantity of haemoglobin in the blood that is saturated with oxygen. Hemoglobin is a component of red blood cells that binds oxygen and transports it to outlying tissues. Oxygen is commonly used throughout the world in neonatal units. Injudicious use of Oxygen may not maintain appropriate oxygen status rather can lead to hypoxemia or hyperoxemia, both of the conditions are injurious to neonatal health. Objective: To assess the oxygen saturation in neonate after birth.Methods:A cross-sectional study conducted in the Department of Neonatology BSMMU, Shahbag, Dhaka, Lab Aid Specialized Hospital, Dhaka, Bangladesh from October 2013 to March 2014. A total 317 patients were selected according to selection criteria. The parents were interviewed with a specific pre-designed and pre-tested questionnaire and some information were gathered by document review. All neonate both term and late preterm (˃34weeks) who would not be anticipated for resuscitation was included.Results:A total 317 neonate were selected according to selection criteria. Among the study subjects more than half were male (57.1%). Rests were female (42.9%). Average gestational age of the study subjects was 37.47± 1.16 (SD) with the range of 34-40. On the other hand average birth weight was 2.88±0.46 (SD) with the minimum birth weight 2.0 kg and maximum weight 4.2 kg. Illustrates the median (IQR) heart rate from one to ten min for preterm versus term births. At one to three minutes and at five minutes after birth preterm infants had significantly lower SpO2 measurements. From six to 10 minutes after birth and four minutes after birth there was no significant difference between SpO2 measurements for mode of delivery. Paired sample t test showed that average SpO2 was less in 1 minute[88.42±4.8(SD)] than in 5 minute [94.25±3.5(SD)] and statistically this differences were highly significant (t=24.44, p=0.000). Pearson correlation showed high positive correlation (p=0.000) and correlation co-efficient r=0.479. Correlation was significant at the 0.01 level.Conclusion:It is “normal” to have low oxygen saturation measurements in the first minutes after birth. It takes time for infants to reach oxygen saturation levels described as “normal” in the later postnatal period. Oxygen saturation increased with time i.e., it was more in 5 minutes than in 1 minute and similarly more in 10 minutes than in 5 minutes. Conversely heart rate was found more in one minute than to five and ten minutes. Oxygen saturation was ≥ 90% within 3 to 4 minutes. Significant changes were found in Oxygen saturation by mode of delivery in three minutes & in heart rate by two minutes after birth. At one to ten minutes after birth preterm infants had lower SpO2 measurements.

Successful pregnancy and delivery management in a patient with Bernard Soulier Syndrome

Bernard Soulier Syndrome (BSS) is an inherited bleeding disorder characterized by macrothrombocytopenia and absence of ristocetin-induced platelet aggregation. Clinical findings vary from person to person. Most of the patients are diagnosed with muco-cutaneous bleeding such as purpura, epistaxis and gingival bleeding in early childhood. Few pregnant women with BSS are described in the literature. Management of thrombocytopenia during pregnancy and delivery requires a multidisciplinary approach. The family should be warned about the potentially life-threatening bleeding during pregnancy and the delivery and the decision about mode of delivery should be individualised, involving discussion with patient and multidisciplinary team.

Effects of Complementary Feeding With Different Protein-Rich Foods on Infant Growth and Gut Health: Study Protocol

Background: An urgent need exists for evidence-based dietary guidance early in life, particularly regarding protein intake. However, a significant knowledge gap exists in the effects of protein-rich foods on growth and development during early complementary feeding.Methods: This is a randomized controlled trial of infant growth and gut health (primary outcomes). We directly compare the effects of dietary patterns with common protein-rich foods (meat, dairy, plant) on infant growth trajectories and gut microbiota development (monthly assessments) during early complementary feeding in both breast- and formula-fed infants. Five-month-old infants (up to n = 300) are randomized to a meat-, dairy-, plant-based complementary diet or a reference group (standard of care) from 5 to 12 months of age, with a 24-month follow-up assessment. Infants are matched for sex, mode of delivery and mode of feeding using stratified randomization. Growth assessments include length, weight, head circumference and body composition. Gut microbiota assessments include both 16S rRNA profiling and metagenomics sequencing. The primary analyses will evaluate the longitudinal effects of the different diets on both anthropometric measures and gut microbiota. The secondary analysis will evaluate the potential associations between gut microbiota and infant growth.Discussion: Findings are expected to have significant scientific and health implications for identifying beneficial gut microbial changes and dietary patterns and for informing dietary interventions to prevent the risk of overweight and later obesity, and promote optimal health.Clinical Trial Registration:www.ClinicalTrials.gov, identifier: NCT05012930.

Prevalence and Postpartum Screening Practice for Type 2 Diabetes following GDM in King Abdulaziz Medical City: A 3-Years Retrospective Cohort Study

Aim: GDM patients were associated to develop T2DM but mostly failed to undergo screening after delivery. This study aims to examine the practice of T2DM screening and prevalence of developing T2DM among women who had GDM in King Abdulaziz Medical City (KAMC), Saudi Arabia. Methods: Retrospective study involving 642 pregnant women with GDM. Medical records on screenings conducted, delivery mode, GDM and diabetes family history were collected and investigated. Statistical analysis was conducted. Frequencies and percentages were used for categorical variables while means and SD for continuous. Chi-square and t-test were used to establish relationship of categorical and comparing two group means, respectively. Results: Patients were 98.8% Saudi nationals, mean weight, height, parity and number of pregnancies were 76.96 kg, 2.74 m, 3.37 and 1.35, respectively. Majority were obese (56.9%), SVD (56.4%) mode of delivery and good lifestyle (91.4%) as management practice. OGTT was used for screening T2DM with 0 hr fasting and 2-hrs after consuming 75g of glucose, physician ordered 6 weeks after delivery. Only 20% had screening for T2DM and 3.9% developed postpartum diabetes with high number of women not returning for ordered OGTT screening (65.6%). Significant predictors identified were parity and mode of delivery for development of T2DM, while only mode of delivery for both screening for T2DM and management of GDM.Conclusion: Low prevalence of developing T2DM but high number of women failed to follow the ordered OGTT screening. Effort on the implementation of OGTT screening for T2DM needs improvement.

Prevalence of Food Allergy among Schoolchildren in Lebanon

<b><i>Introduction:</i></b> Food allergy (FA) is a global health problem with an ongoing rise in prevalence, especially in developed countries. It has been reported to be most prevalent in children, although cases in adults have been increasing as well. FA may lead to life-threatening clinical manifestations. Data in Lebanon and the Middle East are limited. To our knowledge, few studies tackled its prevalence in children in this region. <b><i>Aim:</i></b> This study aims at determining self-reported prevalence of FA in schoolchildren (ages 3–17 years) in Lebanon and describes its characteristics. <b><i>Method:</i></b> Throughout this cross-sectional study, 5 schools from 3 different governorates in Lebanon (Beirut, Mt. Lebanon, and Beqaa) were contacted to participate and 5,312 questionnaires were sent out to be completed by the parents and sent back to the school during May 2019. <b><i>Results:</i></b> 2,610 questionnaires were collected (49.13%). A hundred and forty-eight (6%) children reported to have FA, 58% were males. 80% of them were breastfed, 51% were diagnosed between the ages of 2 and 14 years. Common allergens included cow’s milk and milk products (22.46%), fruits and vegetables (16.58%), eggs (8.02%), and nuts (5.88%). Allergic symptoms included skin reactions (45.08%), gastrointestinal (GI) symptoms (29.53%), respiratory symptoms (14.51%), and systemic symptoms (10.88%). 82% of the population with FA has sought professional advice, out of which 54% were confirmed by a physician. Common methods of diagnosis were IgE test (35.71%), food elimination (27.92%), and skin prick test (18.83%). χ² analysis has shown that a higher percentage of children with FA had skin reactions (58.8%, <i>p</i> = 0.033) and GI symptoms (30.41%, <i>p</i> = 0.047). A higher percentage of children with allergies were breastfed. No relation between the presence of FA and delivery mode was observed. <b><i>Conclusion:</i></b> This study has shown that the self-reported prevalence of FA among Lebanese schoolchildren is 6%, and it was correlated with skin and GI symptoms. The most common allergen was cow’s milk. A higher proportion of children with FA were breastfed. No association between the mode of delivery and FA was found. Larger studies are needed to confirm the above findings.

Implementation and Evaluation of a Digitally Enabled Precision Public Health Intervention to Reduce Inappropriate Gabapentinoid Prescription: Cluster Randomized Controlled Trial

Background Digital technologies can enable rapid targeted delivery of audit and feedback interventions at scale. Few studies have evaluated how mode of delivery affects clinical professional behavior change and none have assessed the feasibility of such an initiative at a national scale. Objective The aim of this study was to develop and evaluate the effect of audit and feedback by digital versus postal (letter) mode of delivery on primary care physician behavior. Methods This study was developed as part of the Veterans’ Medicines Advice and Therapeutics Education Services (MATES) program, an intervention funded by the Australian Government Department of Veterans’ Affairs that provides targeted education and patient-specific audit with feedback to Australian general practitioners, as well as educational material to veterans and other health professionals. We performed a cluster randomized controlled trial of a multifaceted intervention to reduce inappropriate gabapentinoid prescription, comparing digital and postal mode of delivery. All veteran patients targeted also received an educational intervention (postal delivery). Efficacy was measured using a linear mixed-effects model as the average number of gabapentinoid prescriptions standardized by defined daily dose (individual level), and number of veterans visiting a psychologist in the 6 and 12 months following the intervention. Results The trial involved 2552 general practitioners in Australia and took place in March 2020. Both intervention groups had a significant reduction in total gabapentinoid prescription by the end of the study period (digital: mean reduction of 11.2%, P=.004; postal: mean reduction of 11.2%, P=.001). We found no difference between digital and postal mode of delivery in reduction of gabapentinoid prescriptions at 12 months (digital: –0.058, postal: –0.058, P=.98). Digital delivery increased initiations to psychologists at 12 months (digital: 3.8%, postal: 2.0%, P=.02). Conclusions Our digitally delivered professional behavior change intervention was feasible, had comparable effectiveness to the postal intervention with regard to changes in medicine use, and had increased effectiveness with regard to referrals to a psychologist. Given the logistical benefits of digital delivery in nationwide programs, the results encourage exploration of this mode in future interventions.

University Students’ Classroom Emotional Climate and Attitudes during and after COVID-19 Lockdown

With the advent of COVID-19, universities around the world have been forced to move to a fully online mode of delivery because of lockdown policies. This led to a flurry of studies into issues such as internet access, student attitudes to online learning and mental health during lockdown. However, researchers need a validated survey for assessing the classroom emotional climate and student attitudes towards learning in universities that can be used for online, face-to-face or blended delivery. Such a survey could be used to illuminate students’ perceptions of the experiences that make up learning at university level, in terms of such factors as care from teachers, collaboration and motivation. In this article, we report the validation of a University Classroom Emotional Climate (UCEC) questionnaire and an Attitudes to Learning scale, as well as their use in comparing the classroom emotional climate and attitudes during COVID-19 lockdown (fully online delivery) with post-lockdown (mixed-mode delivery). Female students experienced the post-lockdown condition significantly more positively than during lockdown for all scales except Care, while the only significant difference for males between the during and post-lockdown was their choice to engage with learning (Control) and the degree of Challenge that they found with the learning materials.
