Preconception lifestyle intervention reduces long term energy intake in women with obesity and infertility: a randomised controlled trial.

BACKGROUND: The preconceptional period may be an optimal window of opportunity to improve lifestyle. We previously showed that a 6 month preconception lifestyle intervention among women with obesity and infertility was successful in decreasing the intake of high caloric snacks and beverages, increasing physical activity and in reducing weight in the short term. We now report the effects of the preconception lifestyle intervention on diet, physical activity and body mass index (BMI) at 5.5 years (range = 3.7-7.0 years) after the intervention. METHODS: We followed women who participated in the LIFEstyle study, a multicentre RCT in which women with obesity and infertility were assigned to a six-month lifestyle intervention program or prompt infertility treatment (N = 577). Diet and physical activity 5.5 years later were assessed with an 173-item food frequency questionnaire (N = 175) and Actigraph triaxial accelerometers (N = 155), respectively. BMI was calculated from self-reported weight and previously measured height (N = 179). Dietary intake, physical activity, and BMI in the intervention and control group were compared using multivariate regression models. Additionally, dietary intake, physical activity and BMI of women allocated to the intervention arm with successful weight loss during the intervention (i.e. BMI < 29 kg/m2 or ≥ 5% weight loss), unsuccessful weight loss and the control group were compared with ANCOVA. RESULTS: Although BMI did not differ between the intervention and control group 5.5 years after the intervention (- 0.5 kg/m2 [- 2.0;1.1]; P = 0.56), the intervention group did report a lower energy intake (- 216 kcal/day [- 417;-16]; P = 0.04). Women in the intervention arm who successfully lost weight during the intervention had a significantly lower BMI at follow-up compared to women in the intervention arm who did not lose weight successfully (- 3.4 kg/m2 [- 6.3;-0.6]; P = 0.01), and they reported a significantly lower energy intake compared to the control group (- 301 kcal [- 589;-14]; P = 0.04). Macronutrient intake, diet quality, and physical activity did not differ between the intervention and control group, irrespective of successful weight loss during the intervention. CONCLUSIONS: In our study population, a preconception lifestyle intervention led to reduced energy intake 5.5 years later. Additionally, women allocated to the intervention group who were successful in losing weight during the intervention also had a lower BMI at follow-up. This shows the potential sustainable effect of a preconception lifestyle intervention. TRIAL REGISTRATION: This trial was registered on 16 November 2008 in the Dutch trial register; clinical trial registry number NTR1530 .

The association of birth weight and infant growth with physical fitness at 8-9 years of age--the ABCD study.

BACKGROUND: Low birth weight and accelerated infant growth are independently associated with childhood obesity. We hypothesized that birth weight and infant growth are associated with physical fitness in childhood, and thereby could act as a link in the developmental origins of obesity. In addition, we assessed whether these associations were mediated by fat-free mass (FFM), moderate-to-vigorous physical activity (MVPA) or sedentary behavior (SB). METHODS: We assessed physical fitness in 194 children of Dutch ethnicity aged 8.6 (±0.35) years from the ABCD cohort. Aerobic fitness was assessed using the 20-meter multistage shuttle run test (20-m MSRT), and neuromuscular fitness using the standing broad jump (SBJ) test and hand grip strength test. MVPA and SB were measured by accelerometry, and FFM by bioelectrical impedance analysis. Low birth weight was defined as below the 10th percentile and accelerated infant growth as an s.d. score weight gain of >0.67 between birth and 12 months. RESULTS: Children with low birth weight and subsequent accelerated infant growth attained a lower 20-m MSRT score than the remainder of the cohort, adjusted for multiple confounders (P<0.01). Birth weight and infant growth were both independently positively associated with hand grip strength, but not after adjusting for current height and body mass index. There was no association of birth weight or infant growth with SBJ. FFM mediated >75% of the association of birth weight and infant growth with hand grip strength, but FFM, MVPA and SB did not mediate the associations with 20-m MSRT. CONCLUSIONS: Our results indicate that low birth weight and accelerated infant growth might negatively affect childhood aerobic and neuromuscular fitness. Differences in FFM largely explain the developmental origins of neuromuscular fitness. Consequently impaired fitness may constitute a link between low birth weight, accelerated infant growth and obesity. Hence, optimization of fitness in these children may affect their obesity and cardiovascular disease risk.

Associations of infant feeding and timing of linear growth and relative weight gain during early life with childhood body composition.

BACKGROUND: Growth and feeding during infancy have been associated with later life body mass index. However, the associations of infant feeding, linear growth and weight gain relative to linear growth with separate components of body composition remain unclear. METHODS: Of 5551 children with collected growth and infant-feeding data in a prospective cohort study (Amsterdam Born Children and their Development), body composition measured using bioelectrical impedance analysis at the age of 5-6 years was available for 2227 children. We assessed how feeding (duration of full breastfeeding and timing of introduction of complementary feeding) and conditional variables representing linear growth and relative weight gain were associated with childhood fat-free mass (FFM) and fat mass (FM). RESULTS: Birth weight was positively associated with both FFM and FM in childhood, and more strongly with FFM than FM. Faster linear growth and faster relative weight gain at all ages in infancy were positively associated with childhood FFM and FM. The associations with FM were stronger for relative weight gain than for linear growth (FM z score: ß coefficient 0.23 (95% con 0.19 to 0.26), P<0.001 and 0.14 (0.11 to 0.17), P<0.001 per s.d. change in relative weight gain and linear growth between 1 and 3 months, respectively). Compared with full breastfeeding <1 month, full breastfeeding >6 months was associated with lower FM (FM z score: -0.17 (-0.28 to -0.05), P=0.005) and lower FFM (FFM z score: -0.13 (-0.23 to -0.03), P=0.015), as was the introduction of complementary feeding >6 months (FM z score: -0.22 (-0.38 to -0.07), P=0.004), compared with <4 months. CONCLUSIONS: Faster infant weight gain is associated with a healthier childhood body composition when it is caused by faster linear growth. Full breastfeeding >6 months and introduction of complementary feeding >6 months are associated with lower childhood FM.

Neonatal diagnosis of Down syndrome in The Netherlands: suspicion and communication with parents.

OBJECTIVES: To analyse which dysmorphic features are most recognised in newborns with Down syndrome (DS). Furthermore to evaluate the communication techniques used by clinicians to inform parents about the postnatal diagnosis and compare these to current best practice guidelines. STUDY DESIGN: Prospective study of a birth cohort of newborns with DS born between 1 January 2003 and 31 December 2006 registered by the Dutch Paediatric Surveillance Unit (DPSU). RESULTS: A total of 586 children with trisomy 21 were analysed. Most recognised dysmorphic features in DS newborns were 'upslanted palpebral fissures' (74.1%; n = 426), 'hypotonia' (73.7%; n = 424) and 'epicanthic folds' (68.5%; n = 394). The majority of parents were informed about the suspected diagnosis on the day of birth (76.5%; n = 390). Hospital deliveries had a significantly earlier suspected diagnosis (mean age 3-4 days) compared with home deliveries (mean age 7 days) (P < 0.05). In 10% (n = 44), paediatricians described dissatisfaction with the first conversation with parents. In 88.9% (n = 499) parents were both present when the diagnosis was told, however the child was not present during the conversation in 51.3% (n = 288). In 10.8% (n = 61) parents were not informed about local parent support groups or community resources. CONCLUSION: DS is still often diagnosed after birth, usually on the first day of postnatal life. Most identified clinical features were upslanted palpebral fissures, epicanthic folds and hypotonia. Special attention for recognition of all present clinical features is needed for early diagnosis. Appropriate communication with the parents of the message that their child has DS can be difficult. Guidelines can help to make counselling easier and more effective, which in turn may increase parental satisfaction. Not all recommendations for the first conversation with parents were fully implemented in Dutch clinical practice.

Sleep assessment using EEG-based wearables - A systematic review.

Polysomnography (PSG) is the reference standard of sleep measurement, but is burdensome for the participant and labor intensive. Affordable electroencephalography (EEG)-based wearables are easy to use and are gaining popularity, yet selecting the most suitable device is a challenge for clinicians and researchers. In this systematic review, we aim to provide a comprehensive overview of available EEG-based wearables to measure human sleep. For each wearable, an overview will be provided regarding validated population and reported measurement properties. A systematic search was conducted in the databases OVID MEDLINE, Embase.com and CINAHL. A machine learning algorithm (ASReview) was utilized to screen titles and abstracts for eligibility. In total, 60 papers were selected, covering 34 unique EEG-based wearables. Feasibility studies indicated good tolerance, high compliance, and success rates. The 42 included validation studies were conducted across diverse populations and showed consistently high accuracy in sleep staging detection. Therefore, the recent advancements in EEG-based wearables show great promise as alternative for PSG and for at-home sleep monitoring. Users should consider factors like user-friendliness, comfort, and costs, as these devices vary in features and pricing, impacting their suitability for individual needs.

Unsuccessful validation of 2004 model for predicting academic or behavioural limitations after childhood bacterial meningitis.

AIM: In 2004, a model identifying children at risk of academic or behavioural limitations after bacterial meningitis (BM) was presented. Risk factors were male gender, low birthweight, lower educational level of the father, Streptococcus pneumoniae, lower cerebrospinal fluid (CSF) leucocyte count, delay between admission and start of antibiotics, dexamethasone <2 days, seizures and prolonged fever. The aim of this study was to validate that prediction model in an independent cohort. METHODS: Academic or behavioural limitations were determined in 93 Dutch school-age BM survivors. Risk factors for limitations were obtained from medical files. Validation was performed by applying the model in the cohort, then assessing discrimination and goodness of fit. Multiple imputation techniques were used to deal with missing values. RESULTS: Although fit of the model appeared good when it came to similarity of expected and observed cases (p-value of the Hosmer-Lemeshow test 0.24-0.57), discrimination was poor. Area under the curve (AUC) of the receiver operated characteristics (ROC) curve of the model was 0.83 (95% CI: 0.77-0.89) in the development cohort and 0.53 (95% CI: 0.41-0.65) in the validation cohort. CONCLUSION: External validation of the model was unsuccessful. It is not suitable for implementation in practice.

Ethnic differences in maternal underestimation of offspring's weight: the ABCD study.

OBJECTIVE: To determine the ethnic variation in maternal underestimation of their child's weight status and the explanatory role of socio-economic status (SES), acculturation and parental body mass index (BMI). METHOD: A multi-ethnic sample of 2769 normal or overweight/obese children (underweight children excluded) aged 5-7 years was examined (The Amsterdam Born Child and their Development study), comprising five ethnic subgroups: Dutch (n=1744), African descent (n=184), Turkish (n=86), Moroccan (n=161) and other non-Dutch (n=592). Data on mothers' perception of their child's weight status (5-point scale from 'too low' to 'too high'), SES, acculturation, parental BMI and the children's height and weight were collected. Underestimation was defined by comparing maternal perception with the actual weight status of her child (International Obesity Task Force guidelines). Ethnic differences in underestimation were calculated in the normal weight and overweight/obese categories. RESULTS: Underestimation ranged from 3.6 (Dutch) to 15.7% (Moroccan) in normal-weight children, and from 73.0 (Dutch) to 92.3% (Turkish) in overweight/obese children. After correction for ethnic differences in child's BMI, higher odds ratios (ORs) for underestimation were found in the Turkish (normal weight: OR 6.83; 95% confidence interval (CI) 2.33-20.05 and overweight: OR 2.80; 95% CI 1.12-6.98) and Moroccan (normal weight: OR 11.55; 95% CI 5.28-25.26) groups (reference is the Dutch group). Maternal educational level and immigrant generation largely explained the ethnic differences, with a minor contribution of maternal age. After correction, ORs remained higher in the Moroccan group (OR 4.37; 95% CI 1.79-10.62) among the normal-weight children. CONCLUSION: Mothers frequently underestimate the actual weight status of their child, especially mothers from Turkish or Moroccan origin. Having a lower SES, being first-generation immigrant and a young mother are important determinants in explaining these differences. As weight perceptions may affect weight gain and almost all mothers of overweight/obese children underestimate their child's weight, health professionals should help mothers (particularly those from ethnic minority groups) to acquire a realistic perception of their children's weight status.

High levels of antenatal maternal anxiety are associated with altered cognitive control in five-year-old children.

This longitudinal prospective study examined the relation between maternal anxiety during pregnancy and specific aspects of children's cognitive functioning at age five. Antenatal maternal state-anxiety was measured around the 16th week of pregnancy. Children's neurocognitive functioning was examined using a simple reaction time (RT) task, and a choice RT task. Multiple regression analyses in the total sample (N = 922) showed that antenatal anxiety was positively related to children's intra-individual variability in RT in the simple task. In a subsample (n = 100) of women with state-anxiety scores above the 90th percentile, antenatal anxiety was positively associated with mean RT and intra-individual variability in RT in the incompatible trials of the choice RT task. In addition, in this subsample of highly anxious mothers we found a significant positive association in boys but not in girls, between prenatal maternal anxiety and intra-individual variability in RT in the simple task.

Health-related quality of life and its determinants in children and adolescents born with oesophageal atresia.

AIM: Following surgical correction in the neonatal period, patients born with oesophageal atresia have significant co-morbidity, particularly in childhood. This study evaluates health-related quality of life and its determinants such as concomitant anomalies and the presence of respiratory and/or gastro-intestinal symptoms 6-18 years after repair of oesophageal atresia. METHODS: Parents of 24 patients with oesophageal atresia completed the child health questionnaire for parents and 37 patients completed the child form. Gastro-intestinal symptoms were assessed by a validated standardized reflux questionnaire. Results were compared with a healthy reference population. RESULTS: Parents as well as patients themselves scored significantly lower on the domain general health perception. According to parents, general health perception was negatively affected by age at follow-up and concomitant anomalies. Patients reported that reflux symptoms reduced general health perception. CONCLUSION: In this first study describing health-related quality of life in children and adolescents born with oesophageal atresia, we demonstrated that general health remains impaired because of a high incidence of concomitant anomalies and gastrointestinal symptoms in patients with oesophageal atresia when compared with the healthy reference population.

Pulmonary function and exercise capacity in survivors of congenital diaphragmatic hernia.

Congenital diaphragmatic hernia (CDH) is associated with pulmonary hypoplasia and pulmonary hypertension. The objective of this study was to assess pulmonary function and exercise capacity and its early determinants in children and adolescents born with high-risk CDH (CDH-associated respiratory distress within the first 24 h) and to explore the relationship of these findings with CDH severity. Of 159 patients born with high-risk CDH, 84 survived. Of the 69 eligible patients, 53 children (mean+/-SD age 11.9+/-3.5 yrs) underwent spirometry, lung volume measurements and maximal cardiopulmonary exercise testing (CPET). Results of the pulmonary function tests were compared with those from a healthy control group matched for sex, age and height. CDH survivors had a significantly lower forced expiratory volume in 1 s (FEV(1)), forced vital capacity (FVC), FEV(1)/FVC, maximum mid-expiratory flow and peak expiratory flow when compared with healthy controls. The residual volume/total lung capacity ratio was significantly higher. Linear regression analysis showed that gastro-oesophageal reflux disease was an independent determinant of reduced FEV(1) and FVC. CPET results were normal in those tested. High-risk CDH survivors have mild to moderate pulmonary function abnormalities when compared with a healthy matched control group, which may be related to gastro-oesophageal reflux disease in early life. Exercise capacity and gas exchange parameters were normal in those tested, indicating that the majority of patients do not have physical impairment.

Diet and physical activity in pregnancy and offspring's cardiovascular health: a systematic review.

There is increasing evidence linking maternal diet and physical activity before and during pregnancy with offspring's cardiovascular health. Although many studies examined this association, the evidence has not been reviewed systematically. We therefore undertook a systematic review to synthesize evidence examining the association of maternal diet and physical activity before and during pregnancy with offspring's blood pressure and vascular health. We systematically searched the databases MEDLINE and EMBASE from inception to June 30, 2017. Eligibility screening, data extraction and quality assessment were performed by two independent reviewers. A total of 19 articles were included comprising three randomized controlled trials and 16 observational studies. Of the studies that examined the association of interest, 60% (three out of five studies) showed that high maternal carbohydrate intake was associated with higher offspring's blood pressure. Maternal protein intake during pregnancy was negatively associated with offspring carotid intima-media thickness in two out of two studies. No consistent findings for maternal fatty acid intake were found. There were too few studies to draw conclusions on energy intake, fibre intake, protein/carbohydrate ratio, specific foods, dietary patterns and maternal physical activity. Heterogeneity in exposure and outcome assessment hampered pooling. Also, owing to the observational nature of most studies, causality cannot be established. Harmonization of valid exposure and outcome measurements, and the development of core outcome sets are needed to enable more robust conclusions.

The effects of intrauterine insemination and single embryo transfer or modified natural cycle in vitro fertilization on offspring's health-Follow-up of a randomized clinical trial.

OBJECTIVE: Does ovarian hyperstimulation and/or the in vitro procedure of assisted reproduction affect neurodevelopmental and physical health of the offspring? STUDY DESIGN: Infertile couples were randomly allocated to intrauterine insemination with controlled ovarian hyperstimulation (IUI-COH), modified natural cycle in vitro fertilization (IVF-MNC) or single embryo transfer IVF (IVF-SET). We compared neurodevelopmental and physical health in childhood (4-7 years). We used age-appropriate questionnaires to assess behavioral problems (Child Behavior Check List (CBCL)) and executive functioning (Behavior Rating Inventory of Executive Function (BRIEF)). We measured body mass index Z-score, waist- and hip-circumference, body fat percentage, blood pressure Z-scores, pulse wave velocity, glucose, insulin, insulin resistance, total cholesterol, high- and low-density lipoprotein cholesterol, triglycerides, and high sensitivity c-reactive protein. We compared groups by analysis of variance. RESULTS: We examined 191 (57%) of the 333 children born in the study at a mean age of 5.5 years (range 4.0-7.6 years). We found no statistically significant differences between randomization groups in children's neurodevelopmental or physical health indices (all p-values > 0.05). Comparing the outcomes between actual method of conception, including a naturally conceived group, also did not show statistically significant differences. CONCLUSIONS: Although this follow-up study was not powered on childhood outcomes and limited power due to attrition may have hampered detection of subtle effects, we found no indications of differences in neurodevelopmental and physical health between ovarian hyperstimulation and/or the in vitro procedure of assisted reproduction. Future trials should be powered on child outcomes, and aim to optimize follow-up rates to provide answers that are more definitive.

[Purpura fulminans: a rare complication of chickenpox]. / Purpura fulminans, een zeldzame complicatie van waterpokken.

A 3.5-year-old boy presented with purpura on the buttocks extending towards both legs. Two weeks earlier, he had had chickenpox. Because of the rapidly progressing purpura with clinical signs of hypovolaemic shock, he was treated with fresh frozen plasma, packed red blood cells, intravenous immunoglobulins, prednisolone, acyclovir and ceftriaxone. The purpura stopped spreading. In the next few days, the skin at the site of the purpura became necrotic and was excised, as was the subcutis and part of the fascia on both legs and flanks. The right lower leg was amputated and a temporary colostomy was created to prevent faecal contamination of the wounds. The patient recovered and was discharged after three months. Purpura fulminans is a rare complication after a primary infection with varicella zoster virus. A varicella infection may lead to protein S deficiency resulting in diffuse intravascular coagulation and severe skin defects.

A difference in perception of quality of life in chronically ill children was found between parents and pediatricians.

BACKGROUND AND OBJECTIVES: Quality of life measurements can help to estimate the well-being of chronically ill patients, and disclose discrepancies in perception between physicians and patients that might otherwise interfere with the effectiveness of treatment. The objective was to investigate the differences in perception of quality of life between parents of chronically ill children and pediatricians. METHODS: A cross-sectional study was conducted in four tertiary pediatric care centers in The Netherlands. The Health Utilities Index mark 3 (HUI3) was used by 37 pediatricians and 279 parents of patients (children aged 1 to 17 years) with cystic fibrosis admitted either in daycare or for a pneumonia, or patients with newly diagnosed acute lymphoblastic leukemia, juvenile idiopathic arthritis, or asthma. RESULTS: Differences in perception of quality of life between parents and pediatricians appeared to be dependent of the disease. In patients with acute lymphoblastic leukemia (OR 7.4; [95% CI 2.88-18.97], juvenile idiopathic arthritis (4.7; [95% CI 2.00-11.22]), and asthma (2.3; [95% CI 1.13-4.69]) a difference in perception was more likely to occur than in patients with cystic fibrosis admitted in daycare. CONCLUSION: At the onset of a chronic disease, the parents of pediatric patients may be misunderstood by health care professionals, especially in subjective attributes. Assessment of quality of life may contribute to better understanding between pediatricians and parents, and thus may even enhance compliance and treatment effects.

[Late presentation of congenital diaphragmatic hernia]. / Late presentatie van aangeboren hernia diaphragmatica.

A boy aged 6 months and a girl aged 9 months were admitted due to vomiting, among others, and a boy aged 11 months due to pneumonia. It turned out that they had a congenital diaphragmatic hernia. Primary operative repair was performed successfully in all patients, followed by recovery. The older boy experienced a relapse nearly 1 year later, which was treated by surgical correction. Most congenital diaphragmatic hernias present directly after birth, with cyanosis and respiratory distress. However, 10-20% of the cases are discovered after this period. In these children diagnosis can be difficult because of the diverse symptoms such as vomiting, feeding difficulties, tachypnoea or recurrent respiratory tract infections. Physical signs include the absence of breath sounds or the presence of bowel sounds in the chest. Chest X-ray, contrast upper gastrointestinal series or ultrasound imaging confirms the diagnosis. Delay in treatment can lead to complications such as necrosis of the bowel. In young children with acute or chronic respiratory infections or gastrointestinal complaints, a congenital diaphragmatic defect should be considered.

[Increase in the number of reported cases of child abuse following adoption of a structured approach in the VU Medical Centre, Amsterdam, in the period 2001-2004]. / Toename van het aantal gemelde gevallen van kindermishandeling na een gestructureerde aanpak in het VU Medisch Centrum, Amsterdam, 2001/'04.

OBJECTIVE: Description of the characteristics of (suspected) child abuse after the establishment of a Child Abuse Team and the introduction of guidelines on how to deal with child abuse and a standardised registration form for suspicions of child abuse. DESIGN: Retrospective. METHOD: An inventory and analysis of the available data on the reporting of, approach to and care provided in case of(suspected) child abuse from I January 2oo0 to 30 April 2004 in the VU Medical Centre in Amsterdam, the Netherlands. RESULTS: The Child Abuse Team received 220 reports of suspected child abuse and the number of suspected and confirmed cases of child abuse increased each year. In 58 suspected cases, the suspicions were confirmed on the basis of additional information from the general practitioners or other attending physicians, or conversations with the parents and the child. There were 29 girls and 29 boys; 22 of them were from families with multiple problems. Of these 58 confirmed cases, 31 were reported to the national Advisory Centre for Registration of Child Abuse. In 120 of the 220 suspected cases of child abuse, this suspicion was refuted, while in 42 cases the suspicion could neither be refuted nor confirmed. CONCLUSION: An increased number of suspected cases of child abuse were reported and confirmed each year following the introduction of a standardised registration form and subsequent analysis by a multidisciplinary team. Broader application of this approach may contribute to improved insight into the prevalence and causes of child abuse.

Quality of life: patients and doctors don't always agree: a meta-analysis.

OBJECTIVE: In addition to traditional clinical markers, quality-of-life assessment can be helpful to estimate the well-being of patients. Discrepancies in perception of well-being between physicians and patients may interfere with the effectiveness of treatment. A systematic review and meta-analysis were performed to explore the (dis-)agreement in quality-of-life assessments between patients and physicians. STUDY DESIGN AND SETTING: Data on the proportion agreement of paired observations were collected from Medline, Embase, Psychlit, and Social Abstracts. RESULTS: Of the 1,316 articles found, six met the selection criteria, four studied the proportion agreement between children and physicians, and all six the proportion agreement between parents and physicians. None examined the magnitude of over- or underestimation by physicians. The agreement was lower in the more subjective domains (0.54-0.77) in comparison to the more objective domains (0.79-0.94). CONCLUSION: Quality-of-life assessment should be integrated in clinical practice. During long-term treatment the perception of the patients' well-being by physicians and patients themselves can easily diverge from each other, resulting in misunderstandings about the treatment and its usefulness in relation to perceived quality of life, and may even become the base for noncompliance.

[Kernicterus in a full-term male infant a few days old]. / Kernicterus bij een aterm geboren jongen van enkele dagen oud.

A male baby born at term via an uncomplicated vaginal delivery was presented on the fourth day of life with jaundice, accompanied by neurological symptoms related to kernicterus. Despite extensive investigations, a clear cause for his hyperbilirubinaemia could not be found. After 10 days of intensive care he was left with deafness and a severe extrapyramidal motor disturbance. Recently revised practice guidelines suggest a less aggressive approach for the treatment of jaundice with phototherapy or exchange transfusion in newborns. However, in the presence of factors for kernicterus, early and, if necessary, frequent measurement of the serum bilirubin concentration remains important to prevent serious and life-long complications.

[Fever, coughing and/or wheezing in young children: consider the possibility of foreign body aspiration]. / Koorts, hoesten en/of piepen bij jonge kinderen: vergeet het corpus alienum niet.

Three children, 2 girls aged 1.5 and 3 years and a 2-year-old boy, experienced coughing, wheezing and/or fever for several days or weeks. The first girl was treated for asthma, the other two children for pneumonia. Because the symptoms persisted in all three children after treatment was started, the diagnosis of foreign body aspiration was suggested and confirmed by bronchoscopy. The foreign body was removed during the bronchoscopy and in the boy, a mucosal lesion in the piriform fossa was sutured. Thereafter, all the children recovered completely. In children with persistent coughing, wheezing or fever despite treatment for pneumonia or asthma and in absence of a characteristic acute incident, foreign body aspiration should be considered.

No associations of prenatal maternal psychosocial stress with fasting glucose metabolism in offspring at 5-6 years of age.

Highly prevalent maternal psychosocial complaints are accompanied by increases in glucocorticoid stress hormones, which may predispose the offspring for type 2 diabetes and cardiovascular disease later in adulthood. The aim of the current research is to study whether prenatal maternal psychosocial stress is associated with parameters of blood glucose metabolism in their children aged 5-6 years. The study design was a prospective birth cohort (the Amsterdam Born Children and their Development study, the Netherlands). Depressive symptoms, pregnancy-related anxiety, parenting daily hassles and job strain were recorded by questionnaire (gestational week 16). A cumulative score was also calculated. Possible sex differences in the associations were considered. The subjects were 1952 mother-child pairs. Outcome measures were fasting glucose (n=1952), C-peptide and insulin resistance (HOMA2-IR) (n=1478) in the children at the age of 5-6 years. The stress scales, single and cumulative, were not associated with glucose/C-peptide/insulin resistance (all P>0.05). We did not find evidence for sex differences. In conclusion, we did not find evidence for an association between psychosocial stress during early pregnancy and parameters of glucose metabolism in offspring at the age of 5-6 years. Differences emerging later in life or in response to a metabolic challenge should not be ruled out.
