Analysis of hospital cost outcome of DHA-rich fish-oil supplementation in pregnancy: Evidence from a randomized controlled trial.

OBJECTIVE: Recent research emphasized the nutritional benefits of omega-3 long chain polyunsaturated fatty acids (LCPUFAs) during pregnancy. Based on a double-blind randomised controlled trial named "DHA to Optimize Mother and Infant Outcome" (DOMInO), we examined how omega 3 DHA supplementation during pregnancy may affect pregnancy related in-patient hospital costs. METHOD: We conducted an econometric analysis based on ordinary least square and quantile regressions with bootstrapped standard errors. Using these approaches, we also examined whether smoking, drinking, maternal age and BMI could influence the effect of DHA supplementation during pregnancy on hospital costs. RESULTS: Our regressions showed that in-patient hospital costs could decrease by AUD92 (P<0.05) on average per singleton pregnancy when DHA supplements were consumed during pregnancy. Our regression results also showed that the cost savings to the Australian public hospital system could be between AUD15 - AUD51 million / year. CONCLUSION: Given that a simple intervention like DHA-rich fish-oil supplementation could generate savings to the public, it may be worthwhile from a policy perspective to encourage DHA supplementation among pregnant women.

Long term follow up of high risk children: who, why and how?

BACKGROUND: Most babies are born healthy and grow and develop normally through childhood. There are, however, clearly identifiable high-risk groups of survivors, such as those born preterm or with ill-health, who are destined to have higher than expected rates of health or developmental problems, and for whom more structured and specialised follow-up programs are warranted. DISCUSSION: This paper presents the results of a two-day workshop held in Melbourne, Australia, to discuss neonatal populations in need of more structured follow-up and why, in addition to how, such a follow-up programme might be structured. Issues discussed included the ages of follow-up, and the personnel and assessment tools that might be required. Challenges for translating results into both clinical practice and research were identified. Further issues covered included information sharing, best practice for families and research gaps. SUMMARY: A substantial minority of high-risk children has long-term medical, developmental and psychological adverse outcomes and will consume extensive health and education services as they grow older. Early intervention to prevent adverse outcomes and the effective integration of services once problems are identified may reduce the prevalence and severity of certain outcomes, and will contribute to an efficient and effective use of health resources. The shared long-term goal for families and professionals is to work toward ensuring that high risk children maximise their potential and become productive and valued members of society.

Fish-oil supplementation in pregnancy does not reduce the risk of gestational diabetes or preeclampsia.

BACKGROUND: There is uncertainty regarding the efficacy of increasing n-3 long-chain PUFA (LCPUFA) intake during pregnancy in reducing the risk of gestational diabetes mellitus (GDM) and preeclampsia. OBJECTIVES: The objective was to determine whether n-3 LCPUFA supplementation in pregnancy reduces the incidence of GDM or preeclampsia. A secondary objective was to assess the effect of n-3 LCPUFA supplementation on perinatal complications. DESIGN: This was a double-blind, multicenter randomized control trial-the DHA to Optimize Mother Infant Outcome (DOMInO) trial. Pregnant women (n = 2399) of <21 wk gestation were randomly assigned to receive DHA-enriched fish oil (800 mg/d) or vegetable oil capsules without DHA from trial entry to birth. The presence of GDM or preeclampsia was assessed through a blinded audit of medical records. Birth outcomes and prenatal complications were also assessed. RESULTS: The overall incidences of GDM and preeclampsia were 8% and 5%, respectively, based on clinical diagnosis. The RR of GDM was 0.97 (95% CI: 0.74, 1.27) and of preeclampsia was 0.87 (95% CI: 0.60, 1.25), and they did not differ significantly between the groups. Birth weight, length, and head circumference z scores also did not differ between the groups. There were 12 perinatal deaths and 5 neonatal convulsions in the control group compared with 3 perinatal deaths and no neonatal convulsions in the DHA group (P = 0.03 in both cases). CONCLUSION: DHA supplementation of 800 mg/d in the second half of pregnancy does not reduce the risk of GDM or preeclampsia. Whether supplementation reduces the risk of perinatal death and neonatal convulsions requires further investigation. The DOMInO trial was registered with the Australian New Zealand Clinical Trials Registry as TRN12605000569606.

Outcome at 2 years of age of infants from the DART study: a multicenter, international, randomized, controlled trial of low-dose dexamethasone.

OBJECTIVE: Low-dose dexamethasone facilitates extubation in chronically ventilator-dependent infants with no obvious short-term complications. The objective of this study was to determine the long-term effects of low-dose dexamethasone. METHODS: Very preterm (<28 weeks' gestation) or extremely low birth weight (birth weight <1000 g) infants who were ventilator dependent after the first week of life for whom clinicians considered corticosteroids were indicated were eligible. After informed consent, infants were randomly assigned to masked dexamethasone (0.89 mg/kg over 10 days) or saline placebo. Survivors were assessed at 2 years' corrected age by staff blinded to treatment group allocation to determine neurosensory outcome, growth, and health. RESULTS: The trial was abandoned well short of its target sample size because of recruitment difficulties. Seventy infants were recruited from 11 centers, 35 in each group: 59 survived to 2 years of age, and 58 (98%) were assessed at follow-up, but data for cerebral palsy were available for only 56 survivors. There was little evidence for a difference in the major end point, the rate of the combined outcome of death, or major disability at 2 years of age (dexamethasone group: 46%; controls: 43%). Rates of mortality before follow-up (11% vs 20%), major disability (41% vs 31%), cerebral palsy (14% vs 22%), or of the combined outcomes of death or cerebral palsy (23% vs 37%) were not substantially different between the groups. There were no obvious effects of low-dose dexamethasone on growth or readmissions to hospital after discharge. CONCLUSIONS: Although this trial was not able to provide definitive evidence on the long-term effects of low-dose dexamethasone after the first week of life in chronically ventilator-dependent infants, our data indicate no strong association with long-term morbidity.

Low-dose dexamethasone facilitates extubation among chronically ventilator-dependent infants: a multicenter, international, randomized, controlled trial.

OBJECTIVE: Postnatal corticosteroid therapy is controversial. The aim of this study was to determine the short-term effects of low-dose dexamethasone treatment among chronically ventilator-dependent neonates. METHODS: Very preterm (gestational age: <28 weeks) or extremely low birth weight (birth weight: <1000 g) infants who were ventilator dependent after the first 1 week of life were eligible and were assigned randomly to receive masked dexamethasone (0.89 mg/kg over 10 days) or saline placebo. Data on ventilator and oxygen requirements and deaths were recorded. RESULTS: Seventy infants were recruited from 11 centers, at a median age of 23 days. More infants were extubated successfully by 10 days of treatment in the dexamethasone group (60%, 21 of 35 patients) than in the control group (12%, 4 of 34 patients) (odds ratio [OR]: 11.2; 95% confidence interval [CI]: 3.2-39.0). Ventilator and oxygen requirements improved substantially, and the duration of intubation was shorter. There was little evidence for a reduction in either the mortality rate (dexamethasone group: 11%; control group: 20%; OR: 0.52; 95% CI: 0.14-1.95) or the rate of oxygen dependence at 36 weeks (dexamethasone group: 85%; control group: 91%; OR: 0.58; 95% CI: 0.13-2.66). There were no obvious effects of low-dose dexamethasone on blood glucose concentrations, blood pressure, or other complications. No infant experienced intestinal perforation. CONCLUSIONS: Low-dose dexamethasone treatment after the first 1 week of life clearly facilitates extubation and shortens the duration of intubation among ventilator-dependent, very preterm/extremely low birth weight infants, without any obvious short-term complications. Combined with recent evidence that infants at very high risk of bronchopulmonary dysplasia may benefit in the long term, our study reopens debate regarding the role of low-dose, late postnatal, corticosteroid therapy.
