Aim  

To evaluate the effect of necrotizing enterocolitis (NEC) on growth and neurodevelopmental outcome.     

Are the neonatal outcomes similar in large-for-gestational age infants delivered by women with or without gestational diabetes mellitus?

Background

Infants are considered large for gestational age (LGA) if their birth weight is greater than the 90th percentile for gestational age and they have an increased risk for adverse perinatal outcomes. Maternal diabetes is one of the factors affecting birthweight. However there are limited data on the perinatal outcomes of infants of gestational diabetic mothers. The aim of the present study was to compare the neonatal outcomes of LGA infants delivered by women with and without gestational diabetes mellitus.

Methods

This was a retrospective study of LGA infants of ??36 weeks of gestation born at the Gazi University Medical School Hospital during the period of 2006?C2009. Neonatal outcomes included hypoglycemia and polycythemia in the early neonatal period and hospital admissions. The Chi-square and Student??s t test were used for comparing variables.

Results

Seven hundred eligible infant-mother pairs were enrolled in the study. Eighty-seven of them (12.4%) were infants of gestational diabetic mothers and 613 (87.6%) were infants of non-diabetic mothers. The incidence of hypoglycemia at the first hour was higher in infants of diabetic mothers (12.8%) than in infants of non-diabetic mothers (5.3%) (P=0.014). Polycythemia was also more frequently observed in infants of the gestational diabetic mothers (9.3%) than in infants of the non-diabetic mothers (3.0%) (P=0.010). Although overall hospital admission rates were not different between the two groups, infants of diabetic mothers were more likely to be admitted because of resistant hypoglycemia (P=0.045).

Conclusions

The results of this study suggested that LGA infants of mothers with gestational diabetes mellitus were at a greater risk for hypoglycemia and polycythemia in the early neonatal period than LGA infants of nondiabetic mothers.     

Does family functioning affect outcome in children with neurological disorders?

Children with neurological disorders are at increased risk of poor psychological and social adjustment. Medical factors are insufficient to explain the individual variation in outcome, so family variables have been considered. This review evaluates studies which have investigated the effect of family functioning on outcome in children with traumatic brain injuries, epilepsy and other neurological disorders. Methodological problems include the cross-sectional nature of many studies and inadequate control for confounding variables. There is good evidence that family functioning influences behavioural adjustment and adaptive functioning after traumatic brain injury. The role of family functioning in epilepsy and other neurological disorders requires further investigation. The development of effective interventions to improve family functioning may lead to important clinical benefits for children and their families.     

Does bladder augmentation negatively affect renal transplant outcome in posterior urethral valve patients?

ObjectiveAlthough renal transplant (RT) is a safe and effective treatment for end-stage renal disease, the outcome of RT has been mixed for posterior urethral valve (PUV) patients. In addition, some PUV patients need an augmentation cystoplasty (AC), which may negatively affect their RT outcome. The aim of this study is to compare RT outcome between PUV children with and without AC.Materials and methodsBetween 1985 and 2012 a total of 309 children received 369 RTs at our institution. Among these patients, 36 were had classified as having PUV. Of these, 12 underwent an AC before RT (AC group) and 24 did not (controls). Data, including age at transplant, allograft source, urological complications, urinary tract infection (UTI) incidence, the presence of vesicoureteral reflux (VUR), and patient and graft survival, were compared between groups.ResultsMean age at RT and mean follow-up were 7.6 versus 7.9 years and 8.9 versus 7.9 years in the AC group and in the control group, respectively (not significant [NS]). Allografts were from living donors in 50% of the AC group and in 41.6% of the controls (NS). The rate of UTI was 0.02 UTI/patient/year and 0.004 UTI/patient/year in the AC and control group, respectively (p = 0.001). Of the nine patients with UTI in the augmented group, five (55.5%) had VUR, while 5/8 (62.5%) patients in the control group with UTI had VUR. All patients with VUR in either group had UTIs previously. Of the five AC patients with more than three UTIs, two (40%) were non-compliant with clean intermittent catheterization (CIC), and UTI incidence was not associated with either a Mitrofanoff conduit or the urethra being used for CIC. Graft function at the end of study was 87.8 ± 40.5 ml/min/m² in the AC group and 88.17 ± 28.20 ml/min/m² in the control group (NS). The 10-year graft survival rate was 100% in AC group and 84.8% in controls. Two patients in the AC group lost their grafts (mean follow-up 13.3 ± 0.8 years) and five in the control group (mean follow-up 7.1 ± 4.7 years).ConclusionsBladder augmentation does not negatively affect renal outcome in PUV patients undergoing transplantation. However, recurrent UTIs are more frequent in transplanted PUV patients with an AC than in those without AC, and they are generally related to non-compliance with CIC or the presence of VUR but, mostly, they will not result in impaired graft function.     

Does maternal depression predict developmental outcome in 18 month old infants?

Aim

Our aim was to examine the associations between maternal depression in the first 6 months postpartum, home environment and cognitive, language and motor development in infants at 18 months of age.

Study design and methods

This article reports results from the control group (n = 312 full term; n = 48 preterm) of the prospective Docosahexaenoic acid (DHA) to Optimise Maternal Infant Outcome (DOMInO) Randomised Controlled Trial. Mothers in South Australia completed the Edinburgh Postnatal Depression Scale (EPDS) at 6 weeks and 6 months postpartum. Infant development was assessed when children were 18 months old with the Bayley Scales of Infant and Toddler Development Version III and mothers completed the Home Screening Questionnaire at this assessment.

Results

There were no significant associations between maternal depression in the first 6 months postpartum and cognitive, language or motor development after controlling for infant prematurity, breastfeeding status and socio-economic level. Home environment remained a significant predictor of development after controlling for potential confounding variables. Using mediation models, we did not find an association between maternal depression and developmental outcome through home environment.

Conclusions

Maternal depression in the first 6 months postpartum was not associated with infant development at 18 months of age. Further studies should focus on women with chronic depression.     

Is serum zinc status related to gestational diabetes mellitus? A meta‐analysis

Gestational diabetes mellitus (GDM) is a common medical disorder that begins during pregnancy. The present work aimed to investigate the relationship of maternal or foetal circulatory zinc levels with GDM. Related studies were retrieved against the PubMed/Medline, Web of Science, Scopus databases till July 2020. The overall effects were expressed as standard mean difference (SMD). Furthermore, the random effects model was used to assess the summarised risk ratios (SRRs) to determine the relationship between zinc and the risk of GDM. A total of 15 articles involving were retrieved for meta‐analysis; in the meantime, 4955 subjects including 1549 GDM cases were enrolled for quantitative analysis. Compared with normal control, GDM cases had decreased circulating zinc level on the whole, but the difference was not statistically significant (SMD = −0.40, 95%CI: −0.80 to −0.00, P = 0.05). Interestingly, upon subgroup analysis stratified by serum zinc content but not plasma zinc concentration, there was significant difference in zinc content between GDM cases and normal controls (SMD = −0.56; 95%CI: −1.07 to −0.04, P = 0.03). Meanwhile, subgroup analysis also revealed similar tendency among the Asians and during the 2nd trimester, but not among the Caucasians or during the 1st or 3rd trimester. Data extracted from four studies that compared pregnant women with GDM in the high level of zinc and GDM in the low level of zinc yielded an SRR of 0.929 (95%CI: 0.905–0.954). According to existing evidence, the serum zinc content decreases among GDM cases compared with subjects with no abnormality in glucose tolerance, in particular among the Asians and during the second trimester. Nonetheless, more well designed prospective study should be carried out for understanding the dynamic relationship of zinc level with the incidence of GDM.

Does Down syndrome affect the outcome of congenital duodenal obstruction?

Congenital duodenal obstruction (DO) has a well-known association with Down syndrome (DS) and other congenital malformations. Previously reported series on DO have not examined the influence of DS on associated congenital malformations and postoperative morbidity and mortality. We report on a retrospective study of all children born with DO over an 11-year period to investigate this. A total of 79 patients with DO were studied: group 1 consisted of 51 (64.6%) children without DS, and group 2 consisted of 28 (35.4%) children with DS. There was no significant difference in mean gestational age and birth weight between groups 1 and 2. A coexisting congenital malformation was found in 68% of patients. Gastrointestinal malformations were the most common in group 1 (71.1%), and cardiac malformations were the most common in group 2 (81.5%). The mean time to reach full intragastric feeds was 12 days, with no significant difference between the two groups (p=0.383). Seven (8.9%) patients developed a postoperative complication, with no significant difference between both groups (p=0.853). A total of 11 patients died: six (12%) in group 1 and five (28%) in group 2, with no significant difference between the groups (p=0.454). DS does not influence the morbidity and mortality of DO but does carry a higher incidence of congenital cardiac abnormalities. Delayed mortality was a result of coexisting congenital cardiac and respiratory disease.     

Might asphyxia cause respiratory inhibition after crying in mature infants?

Background: To clarify the timing of injury in utero causing respiratory inhibition after crying (RIAC), the relationship between asphyxia and RIAC was investigated in infants whose gestational age was ≥36 weeks. Methods: RIAC and cranial ultrasound abnormalities were examined for retrospectively in infants treated in the neonatal intensive care unit from April 2004 through March 2009. All included infants were gestational age ≥36 weeks and had an Apgar score <4 points at 1 min. The relationship between RIAC and perinatal factors was also examined. Results: Twenty‐six infants were included. Three infants had RIAC, seven infants had poor prognosis, and nine infants had ultrasound abnormalities in the ganglionic eminence (GE). There was a significant relationship between RIAC and ultrasound abnormalities in the GE (P= 0.032). Poor prognosis was significantly associated with low Apgar score at 5 min (P≤ 0.001), disseminated intravascular coagulation (P= 0.047), hypoxic ischemic encephalopathy (P= 0.028), and brain hypothermia therapy (P= 0.028). There was no significant relationship between RIAC and poor prognosis. All infants had ultrasound abnormalities in the GE on the day of birth. Conclusion: Damage occurring in utero prior to 36 weeks gestation might cause increased echogenicity or cyst formation in the GE, potentially disturbing maturation of the respiratory center with the development of RIAC.     

Does gastroesophageal reflux cause apnea in preterm infants?

Gastroesophageal reflux (GER) and apnea are both common occurrences in premature infants but their relationship is controversial. We present the evidence for and against an association between GER and apnea and discuss the merits and limitations of the various methodologies employed in characterizing such a relationship. Overall, GER and apnea do not appear temporally related in preterm infants, despite strong physiologic evidence that stimulation of laryngeal afferents elicits central apnea and laryngeal adduction. In a subpopulation of infants with neurodevelopmental compromise, there may be an increased incidence of both apnea and GER, although the direct association between GER and apnea in this population is unclear. Therefore, we believe there is no evidence to support widespread use of anti-reflux medications in the treatment of apnea in preterm infants. Further studies are needed to clarify the existence of a small subpopulation of infants who may have GER-induced apnea, to identify potential triggering mechanisms, and to document benefit from newer pharmacological approaches.     

Standardized multilevel transition program: Does it affect renal transplant outcome?

The transfer of renal transplant patients from pediatric to adult care is a crucial step with a high risk of subsequent graft loss. Therefore, the transition should be a thoroughly planned, well‐designed and multidisciplinary process focused on the individual patient. Our pediatric nephrology department introduced a structured step‐by‐step transition program supported by a multidisciplinary team of health professionals. The purpose of our study was to determine the effects of the transition program on eGFR and number of ARs in comparison to a group without a transition program at one and three yr after transfer. We conducted a single‐center retrospective cohort study of renal transplant patients prior to and after the introduction of the transition program. Multiple regression analysis revealed a significantly lower decline of eGFR in the group with transition program (?11.3 ± 44 mL/min/1.73 m²) compared to the group without transition program (?28.4 ± 33 mL/min/1.73 m²) at three yr after transfer. The number of AR episodes significantly decreased from 34.6% in the group without transition program to 9.1% in the group with transition program. The standardized multilevel transition program seems to have significant positive effects on eGFR and number of AR episodes in renal transplant patients.     

Does breastfeeding influence the risk of developing diabetes mellitus in children? A review of current evidence

Objectivethe aim of this study was to perform a review to investigate the influence of breastfeeding as a protective agent against the onset of diabetes in children.Sourcesnon-systematic review of SciELO, LILACS, MEDLINE, Scopus, and VHL databases, and selection of the 52 most relevant studies. A total of 21 articles, specifically on the topic, were analyzed (nine related to type 1 diabetes and 12 to type 2 diabetes).Data synthesisthe duration and exclusivity of breastfeeding, as well as the early use of cow's milk, have been shown to be important risk factors for developing diabetes. It is believed that human milk contains substances that promote the maturation of the immune system, which protect against the onset of type 1 diabetes. Moreover, human milk has bioactive substances that promote satiety and energy balance, preventing excess weight gain during childhood, thus protecting against the development of type 2 diabetes. Although the above mentioned benefits have not been observed by some researchers, inaccuracies on dietary habit reports during childhood and the presence of interfering factors have been considered responsible for the lack of identification of beneficial effects.Conclusiongiven the scientific evidence indicated in most published studies, it is believed that the lack of breastfeeding can be a modifiable risk factor for both type 1 and type 2 diabetes. Strategies aiming at the promotion and support of breastfeeding should be used by trained healthcare professionals in order to prevent the onset of diabetes.
