Spaced scenario demonstrations improve knowledge and confidence in pediatric acute illness management

Objectives: Nationally accredited simulation courses such as advance pediatric life support and pediatric advance life support are recommended for health care professionals (HCPs) at two yearly intervals as a minimum requirement, despite literature evidence suggesting rapid decline in knowledge shortly after course completion. The objective of this study was to evaluate an observation-based, educational intervention program aimed at improving previously acquired knowledge and confidence in managing critical illnesses. Methods: A prospective cohort longitudinal study was conducted over a 6-month period. Participants were assessed with a knowledge based questionnaire immediately prior to and after observing 12 fortnightly critical illness scenario demonstrations (CISDs). The outcome measure was performance on questionnaires. Regression analysis was used to adjust for potential confounders. Questionnaire practice effect was evaluated on 30 independent HCPs not exposed to the CISDs. Results: Fifty-four HCPs (40 doctors and 14 nurses) participated in the study. All participants had previously attended nationally accredited simulation courses with a mean time since last attendance of 1.8 ± 0.4 years. The median number of attendances at CISD was 6 (2–12). The mean questionnaire scores at baseline (17.2/25) were significantly lower than the mean post intervention questionnaire scores (20.3/25), p = 0.003. The HCPs self-rated confidence in managing CISD was 6.5 times higher at the end of the program in the intervention group (p = 0.002) than at baseline. There was no practice effect for questionnaires demonstrated in the independent sample. Conclusion: The educational intervention program significantly improved the knowledge and confidence of the participants in managing pediatric critical illnesses. The CISD program provides an inexpensive, practical, and time effective method of facilitating knowledge acquisition and retention. Despite the distinctively different approach, this study has shown the effectiveness of the participant being an observer to enhance pediatric resuscitation skills.6 page(s

Gestational diabetes independently increases birth length and augments the effects of maternal BMI on birth weight: a retrospective cohort study.

Objective To investigate the effect of the interaction between gestational diabetes (GDM) and maternal body mass index (BMI) on the individual neonatal growth parameters.Design Retrospective cohort studySetting A tertiary maternity service in Sydney, Australia, between 2005 and 2009.Population A cohort of 8859 women.Methods Generalized linear models.Main Outcome MeasuresNeonatal growth parameters, represented by z-scores for infant birth weight, birth length and head circumference in GDM and non-GDM groups. Results Only GDM alone had an independent and positive effect on birth length (p=0.02) but not on birth weight or head circumference. In addition, in pregnancies complicated with GDM, the association between maternal weight and birth weight was significantly stronger (p<0.001). In combination, GDM and maternal BMI significantly affected z-score differences between birth weight and birth length (p<0.001), in that underweight mothers had babies which were lighter relative to their length and inversely obese mothers had babies which were heavier relative to their length. Conclusions GDM independently influences birth length and increases the association between maternal BMI and birth weight. In accordance with the hypothesis of the fetal origins of health and disease, the pronounced effects of GDM on fetal growth patterns demonstrated in this study are likely to influence long-term health outcomes in children

The Effect of Cigarette Smoking during Pregnancy on Endocrine Pancreatic Function and Fetal Growth: A Pilot Study

IntroductionCigarette smoking in pregnancy is a common cause of fetal growth restriction. We aimed to investigate endocrine pancreatic function of mother–infant dyads in relation to cigarette smoking, as a possible mechanism for the poor fetal growth.MethodsProspective study of smoking mothers (10 cigarettes or more per day, self-reported to the midwife) and non-smoker control mothers during their first pregnancy. Insulin, glucose, C-peptide, HbA1C, fructosamine, prolactin, serotonin, and cortisol were measured in maternal blood at 24–26 weeks and in umbilical cord blood at birth. Cotinine was also measured in cord blood.ResultsOf 37 smokers and 36 non-smokers recruited, cord blood was obtainable from 38 babies (19 in each group). In utero cigarette exposure was associated with lower birthweight (3,035 ± 490 versus 3,405 ± 598 g, p = 0.005), with linear modeling of the smoking cohort showing a 41 g reduction for every increase of one cigarette smoked per day (95% CI −71 to −11 g, p = 0.010). There were no differences between groups in indices of maternal or perinatal endocrine pancreatic dysfunction. Heavier smoking independently correlated with higher maternal fasting levels of glucose (p = 0.044) and C-peptide (p = 0.011). We did not observe any significant associations between the daily number of cigarettes and any of the cord blood parameters. We also looked for differences between cohorts based on infant gender. Serotonin levels were higher in smoking mothers with male fetuses (p = 0.01 to p = 0.004).ConclusionEndocrine pancreatic dysfunction does not appear to be a major contributing factor to nicotine-associated fetal growth restriction. The higher serotonin levels in smoking mothers carrying male infants is of uncertain significance but could be a manifestation of gender differences in susceptibility to the long-term effects of cigarette smoking

Gestational diabetes independently increases birth length and augments the effects of maternal BMI on birth weight : a retrospective cohort study

Objective: To investigate the effect of the interaction between gestational diabetes mellitus (GDM) and maternal body mass index (BMI) on the individual neonatal growth parameters. Design: Retrospective cohort study. Setting: A tertiary maternity service in Sydney, Australia, between 2005 and 2009. Population: A cohort of 8859 women. Methods: Generalized linear models. Main outcome measures: Neonatal growth parameters, represented by z-scores for infant birth weight (BW), birth length (BL), and head circumference (HC) in GDM and non-GDM groups. Results: Only GDM alone had an independent and positive effect on BL (p = 0.02) but not on BW or HC. In addition, in pregnancies complicated with GDM, the association between maternal weight and BW was significantly stronger (p < 0.001). In combination, GDM and maternal BMI significantly affected z-score differences between BW and BL (p < 0.001), in that underweight mothers had babies that were lighter relative to their length and inversely obese mothers had babies that were heavier relative to their length. Conclusion: GDM independently influences BL and increases the association between maternal BMI and BW. In accordance with the hypothesis of the fetal origins of health and disease, the pronounced effects of GDM on fetal growth patterns demonstrated in this study are likely to influence long-term health outcomes in children.6 page(s
