Predictors of psychological functioning in mothers and fathers of infants born with severe congenital heart disease

This study examined mental health and coping styles in both mothers and fathers of infants born with a severe congenital heart defect. Factors associated with mental health outcomes were elucidated. Parents of 70 infants, recently born with a severe congenital heart defect, completed questionnaires which examined psychological functioning and coping strategies. Disease, surgical and psychosocial factors were examined for their significance in predicting psychological functioning. Findings indicated elevated levels of clinically significant psychological distress in mothers, compared to fathers, and differences between parents in coping styles. Regression analyses suggested that the extent of distress in both parents was not primarily predicted by illness or demographic factors. Rather, certain coping styles, knowledge, subjective worry and family functioning emerged as significant predictive variables. Implications for early intervention are discussed.

Aqueous shunts for intractable glaucoma in infants

Purpose. To evaluate the utility of aqueous shunt implants in the treatment of infantile glaucoma refractory to conventional therapy. Methods. We retrospectively studied 10 eyes of 7 infants (mean age 12.4 ± 12.7 months) with uncontrolled glaucoma, who were managed with aqueous shunt implants. Adjunctive antimetabolites were used in 4 eyes. Results. The mean intraocular pressure before surgery was 32.2 ± 5.6 mmHg and the final was 17.7 ± 4.9 mmHg at a mean follow up of 11.5 ± 14.9 months. Two eyes (20%) required further glaucoma surgery. No major complications directly related to the aqueous shunt surgery were observed. Conclusions. Aqueous shunts can be effective in the management of intractable glaucoma in infants.

Aqueous shunts for intractable glaucoma in infants

BACKGROUND AND OBJECTIVE: To evaluate the long-term outcome of aqueous shunts in the treatment of infantile glaucoma refractory to conventional treatment. PATIENTS AND METHODS: The records of all patients up to 3 years of age managed with aqueous shunts for uncontrolled glaucoma between November 1990 and November 1996 were retrospectively reviewed. Ten eyes of 6 patients were included in the study. RESULTS: The mean preoperative intraocular pressure (IOP) was 29.75 ± 4.15 (mm Hg; SD), with none of the eyes on antiglaucoma medication. Postoperatively, the mean IOP was 18.25 ± 5.34 (mm Hg; SD) at a mean follow up of 50 ± 25.6 (SD) months with 7 eyes on topical antiglaucoma medication. At the final follow up, 6 eyes were considered successfully controlled without reintervention, 2 more were controlled after shunt revision, and 2 were considered failures. CONCLUSIONS: Aqueous shunts were relatively effective in this series of infants with recalcitrant glaucoma.

Known risk factors for violence predict 12-month-old infants' aggressiveness with peers

This study tested the hypothesis that 12-month-old infants' use of force against peers is associated with known risk factors for violence. We conducted a prospective longitudinal study, which included laboratory observations of firstborn British infants (N = 271) during simulated birthday parties. No gender differences in aggressiveness were observed. The infants' observed aggressiveness was significantly correlated with mothers' mood disorder during pregnancy and with mothers' history of conduct problems. Infants' observed aggressiveness was correlated with parents' ratings of infants' anger and aggression, which were also predicted by mothers' mood disorder and history of conduct problems. Our findings indicate that infants at risk for serious aggression can already be identified when the motor ability to use physical force first enters the human repertoire.

Trait directed de novo population transcriptome dissects genetic regulation of a balanced polymorphism in phosphorus nutrition/arsenate tolerance in a wild grass Holcus lanatus

The aim of this study was to characterize the transcriptome of a balanced polymorphism, under the regulation of a single gene, for phosphate fertilizer responsiveness/arsenate toler- ance in wild grass Holcus lanatus genotypes screened from the same habitat.

De novo transcriptome sequencing, RNAseq (RNA sequencing) and single nucleotide poly- morphism (SNP) calling were conducted on RNA extracted from H.lanatus. Roche 454 sequencing data were assembled into c. 22 000 isotigs, and paired-end Illumina reads for phosphorus-starved (P) and phosphorus-treated (P+) genovars of tolerant (T) and nontoler- ant (N) phenotypes were mapped to this reference transcriptome.

Heatmaps of the gene expression data showed strong clustering of each P+/P treated genovar, as well as clustering by N/T phenotype. Statistical analysis identified 87 isotigs to be significantly differentially expressed between N and T phenotypes and 258 between P+ and P treated plants. SNPs and transcript expression that systematically differed between N and T phenotypes had regulatory function, namely proteases, kinases and ribonuclear RNA- binding protein and transposable elements.

A single gene for arsenate tolerance led to distinct phenotype transcriptomes and SNP pro- files, with large differences in upstream post-translational and post-transcriptional regulatory genes rather than in genes directly involved in P nutrition transport and metabolism per se.

Prenatal and postnatal inflammation in relation to cortisol levels in preterm infants at 18 months corrected age

Objective

To examine whether early inflammation is related to cortisol levels at 18 months corrected age (CA) in children born very preterm.

Study Design

Infants born ≤ 32 weeks gestational age were recruited in the NICU, and placental histopathology, MRI, and chart review were obtained. At 18 months CA developmental assessment and collection of 3 salivary cortisol samples were carried out. Generalized least squares was used to analyze data from 85 infants providing 222 cortisol samples.

Results

Infants exposed to chorioamnionitis with funisitis had a significantly different pattern of cortisol across the samples compared to infants with chorioamnionitis alone or no prenatal inflammation (F[4,139] = 7.3996, P <.0001). Postnatal infections, necrotizing enterocolitis and chronic lung disease were not significantly associated with the cortisol pattern at 18 months CA.

Conclusion

In children born very preterm, prenatal inflammatory stress may contribute to altered programming of the HPA axis.

Neonatal intensive care and late preterm infants:Health and family functioning at three years

Background: Late preterm infants (LPIs), born at 34 + 0 to 36 + 6 weeks of gestation contribute a significant proportion of all neonatal intensive care (NIC) admissions and are regarded as being at risk of adverse outcomes compared to term-born infants.

Aim: To explore the health outcomes and family functioning of LPIs who required neonatal intensive care, at three years of age.

Study design and subjects: This cohort study included 225 children born late preterm, between 1 January and 31 December 2006 in Northern Ireland. Children admitted for NIC (study group, n = 103) were compared with children who did not require NIC or who required special care only for up to three days (comparison group, n = 122).

Outcome measures
Health outcomes were measured using the Health Status Questionnaire, health service usage by parent report and family functioning using the PedsQL™ Family Impact Module.

Results: LPIs who required NIC revealed similar health outcomes at three years in comparison to those who did not. Despite this, more parents of LPIs who required NIC reported visiting their GP and medical specialists during their child's third year of life. Differences in family functioning were also observed with mothers of LPIs who required NIC reporting, significantly lower levels of social and physical functioning, increased difficulties with communication and increased levels of worry.

Conclusions: LPIs were observed to have similar health outcomes at three years of age regardless of NIC requirement. The increase in GP and medical specialist visits and family functioning difficulties observed among those infants who required NIC merits further investigation.

Behavioural outcomes at 3 years of age among late preterm infants admitted to neonatal intensive care: a cohort study

Objective: Examine the behavioural outcomes at age 3 years of late preterm infants (LPIs) who were admitted to neonatal intensive care (NIC) in comparison with LPIs who were not admitted.
Method: This cohort study prospectively recruited 225 children born late preterm (34–36+6 weeks gestation) in 2006 in Northern Ireland, now aged 3 years. Two groups were compared: LPIs who received NIC (study; n=103) and LPIs who did not receive NIC (control; n=122). Parents/guardians completed the Child Behaviour Checklist/1½-5. Descriptive maternal and infant data were also collected.
Results: As expected LPI children admitted to NIC had higher medical risk than the non-admitted comparison group (increased caesarean section, born at earlier gestation, lower birth weight and an episode of resuscitation at birth). LPIs admitted to NIC scored higher on the Child Behaviour Checklist/1½-5 compared with those who were not admitted indicating more behavioural problems; this was statistically significant for the Aggressive Behaviour Subscale (z=−2.36) and the Externalising Problems Scale (z=−2.42). The group difference on the Externalising Problems Scale was no longer significant after controlling for gender, gestational age and deprivation score.
Conclusions: This study provides valuable data on the behaviour at age 3 years of LPIs admitted to NIC compared with LPIs not admitted to NIC. Further research would be beneficial to explore medical and psychosocial explanations for observed differences between groups using large prospective cohort studies.

Women’s Perceptions and Experiences of Fetal Macrosomia

Objective
to explore women's perceptions and experiences of pregnancy and childbirth following birth of a macrosomic infant (birth weight ≥4000 g).

Methods
a qualitative design utilising interviews conducted 13–19 weeks post partum in women's homes. The study was conducted in one Health and Social Care Trust in Northern Ireland between January and September 2010. Participants were identified from a larger cohort of women recruited to a prospective study exploring the impact of physical activity and nutrition on macrosomia. Eleven women who delivered macrosomic infants participated in this phase of the study.

Findings
four overarching themes emerged: preparation for delivery; physical and emotional impact of macrosomia; professional relations and perceptions of macrosomia. Findings highlighted the importance of communication with health professionals in relation to both prediction of macrosomia and decision making about childbirth, and offers further understanding into the physical and emotional impact of having a macrosomic infant on women. Furthermore, there was evidence that beliefs and perceptions relating to macrosomia may influence birth experiences and uptake of health promotion messages.

Key conclusions and implications for practice
this study provides important insight into women's experiences of macrosomia throughout the perinatal period and how they were influenced by previous birth experiences, professional relations and personal perceptions and beliefs about macrosomia. Pregnant women at risk of having a macrosomic infant may require extra support throughout the antenatal period continuing into the postnatal period. Support needs to be tailored to the woman's information needs, with time allocated to explore previous birth experiences, beliefs about macrosomia and options for childbirth.
