The ProPrems trial: investigating the effects of probiotics on late onset sepsis in very preterm infants
BACKGROUND: Late onset sepsis is a frequent complication of prematurity associated with increased mortality and morbidity. The commensal bacteria of the gastrointestinal tract play a key role in the development of healthy immune responses. Healthy term infants acquire these commensal organisms rapidly after birth. However, colonisation in preterm infants is adversely affected by delivery mode, antibiotic treatment and the intensive care environment. Altered microbiota composition may lead to increased colonisation with pathogenic bacteria, poor immune development and susceptibility to sepsis in the preterm infant.Probiotics are live microorganisms, which when administered in adequate amounts confer health benefits on the host. Amongst numerous bacteriocidal and nutritional roles, they may also favourably modulate host immune responses in local and remote tissues. Meta-analyses of probiotic supplementation in preterm infants report a reduction in mortality and necrotising enterocolitis. Studies with sepsis as an outcome have reported mixed results to date.Allergic diseases are increasing in incidence in "westernised" countries. There is evidence that probiotics may reduce the incidence of these diseases by altering the intestinal microbiota to influence immune function. METHODS/DESIGN: This is a multi-centre, randomised, double blinded, placebo controlled trial investigating supplementing preterm infants born at < 32 weeks' gestation weighing < 1500 g, with a probiotic combination (Bifidobacterium infantis, Streptococcus thermophilus and Bifidobacterium lactis). A total of 1,100 subjects are being recruited in Australia and New Zealand. Infants commence the allocated intervention from soon after the start of feeds until discharge home or term corrected age. The primary outcome is the incidence of at least one episode of definite (blood culture positive) late onset sepsis before 40 weeks corrected age or discharge home. Secondary outcomes include: Necrotising enterocolitis, mortality, antibiotic usage, time to establish full enteral feeds, duration of hospital stay, growth measurements at 6 and 12 months' corrected age and evidence of atopic conditions at 12 months' corrected age. DISCUSSION: Results from previous studies on the use of probiotics to prevent diseases in preterm infants are promising. However, a large clinical trial is required to address outstanding issues regarding safety and efficacy in this vulnerable population. This study will address these important issues.

NeOProM: Neonatal Oxygenation Prospective Meta-analysis Collaboration study protocol
Background: The appropriate level of oxygenation for extremely preterm neonates ( 90%) have been reported to have greater rates of morbidity including retinopathy of prematurity and chronic lung disease. In order to answer this clinical dilemma reliably, large scale trial evidence is needed.Methods/Design: To detect a small but important 4% increase in death or severe disability in survivors, over 5000 neonates would need to be recruited. As extreme prematurity affects 1% of births, such a project undertaken by one trial group would be prohibitively lengthy and expensive. Hence, the Neonatal Oxygenation Prospective Meta-analysis (NeOProM) Collaboration has been formed. A prospective meta-analysis (PMA) is one where studies are identified, evaluated, and determined to be eligible before the results of any included studies are known or published, thereby avoiding some of the potential biases inherent in standard, retrospective meta-analyses. This methodology provides the same strengths as a single large-scale multicentre randomised study whilst allowing greater pragmatic flexibility. The NeOProM Collaboration protocol (NCT01124331) has been agreed prior to the results of individual trials being available. This includes pre-specifying the hypotheses, inclusion criteria and outcome measures to be used. Each trial will first publish their respective results as they become available and the combined meta-analytic results, using individual patient data, will be published when all trials are complete. The primary outcome to be assessed is a composite outcome of death or major disability at 18 months - 2 years corrected age. Secondary outcomes include several measures of neonatal morbidity. The size of the combined dataset will allow the effect of the interventions to be explored more reliably with respect to pre-specified patient- and intervention-level characteristics.Discussion: Results should be available by 2014

Psychosocial Functioning in Adults with Congenital Craniofacial Conditions
OBJECTIVE: To examine the psychosocial functioning of adults with congenital craniofacial conditions relative to normative data. DESIGN: Single sample cross-sectional design. SETTING: The Australian Craniofacial Unit, Womenâs and Childrenâs Hospital, Adelaide, which is one of the main craniofacial treatment centers in Australia. PARTICIPANTS: Adults (N = 93) with congenital craniofacial conditions (excluding cleft lip/palate) who were treated in the Australian Craniofacial Unit. MAIN OUTCOME MEASURES: All participants completed self-report scales assessing health-related quality of life (SF-36); life satisfaction, anxiety, and depression (HADS); self-esteem (Rosenberg); appearance-related concerns; perceived social support; and social anxiety. RESULTS: Overall, participants were very similar in psychosocial function to the general population. However, adults with craniofacial conditions were less likely to be married and have children (females), were more likely to be receiving a disability pension, and reported more appearance-related concerns and less social support from friends. They also reported more limitations in both their social activities, due to physical or emotional problems, and usual role activities, because of emotional problems, as well as poorer mental health. CONCLUSIONS: These results give cause to be very positive about the longterm outcomes of children who are undergoing treatment for craniofacial conditions, while also identifying specific areas that interventions could target.R.M.
