Background:We have shown in a previous population-based study significant correlation between childhood asthma and early abnormalities of lipid and glucose metabolism. This study's specific aim was to determine whether maternal nutrition in pregnancy affects postnatal metabolic and respiratory outcomes in the offspring.Methods:On gestation day 1, dams were switched from standard chow to either high-fat hypercaloric diet or control diet. Terminal experiments were performed on newborn and weanling offspring of dams fed the study diet during gestation and lactation, and on adult offspring maintained on the same diet as their mother.Results:Pups born from high-fat hypercaloric diet (HFD) dams developed metabolic abnormalities persistent throughout development. Cytokine expression analysis of lung tissues from newborns born to HFD dams revealed a strong proinflammatory pattern. Gene expression of neurotrophic factors and receptors was upregulated in lungs of weanlings born to HFD dams, and this was associated to higher respiratory system resistance and lower compliance at baseline, as well as hyperreactivity to aerosolized methacholine. Furthermore, HFD dams delivered pups prone to develop more severe disease after respiratory syncytial virus (RSV) infection.Conclusion:Maternal nutrition in pregnancy is a critical determinant of airway inflammation and hyperreactivity in offspring and also increases risk for bronchiolitis independent from prepregnancy nutrition.

Where is the patient's voice in health professions education (HPE)?The notion of 'Nothing about us without us' is endorsed by the World Health Organization framework on integrated person-centred health services 1 that emphasises the importance of co-development between health care professionals and the people using health services. This has resulted in a change of relationship between patients and health care professionals from traditional paternalism towards shared decision making that involves active and equal health care partnerships. 2 This trend towards patient and community involvement in health care was further extended in the 2015 Vancouver

Our data indicate that airborne RSV-laden particles can be detected in pediatric outpatient clinics during the epidemic peak. However, RSV airborne transmission is highly inefficient. Thus, the logistical and financial implications of mandating the use of masks and goggles to prevent RSV spread seem unwarranted in this setting.

Prematurity and low birth weight have been exclusion criteria for extracorporeal membrane oxygenation (ECMO); however, these criteria are not evidence based. With advances in anticoagulation, improved technology, and surgical expertise, it is difficult to deny a potential therapy based on these criteria alone. We report the outcome of three neonates who were ineligible based on traditional criteria but were offered ECMO as a life-saving measure. We highlight the interdisciplinary nature of modern decision-making. All three neonates had severe congenital diaphragmatic hernia diagnosed prenatally, had normal fetal karyotypes, were born prematurely, and weighed less than 2 kg. All three neonates underwent cervical venoarterial cannulation, stabilization on ECMO, and repair of their congenital diaphragmatic hernia early in their ECMO courses. All three infants had long courses of respiratory support attributable to lung hypoplasia, but there were no short- or long-term complications attributable to ECMO support directly. All three are alive at 2 years of age and were making progress developmentally. In conclusion, with interdisciplinary collaboration and clinical guidelines uniformly implemented, low birth weight infants may benefit from ECMO and should not be denied the therapy arbitrarily based on gestational age or size alone. Further research is essential to determine appropriate patient selection in premature infants.

Data regarding availability of prostaglandin E1 (PGE) and its impact on the stabilization, transport, critical care course, and surgical outcome of infants with ductal-dependent congenital heart disease in the current pediatric healthcare environment are unknown. We sought to determine the proportion of hospitals in Texas that stock PGE and to investigate associations between PGE availability and clinical outcomes. All birth institutions listed with the Texas Department of Health and Human Services were contacted to determine PGE availability as of 2011. Outcomes of all infants admitted to our institution from 2007 to 2012 who received PGE for ductal-dependent lesions were evaluated. PGE was stocked in 50 % (n = 139) of hospitals that performed deliveries in Texas in 2011 representing 79.1 % (303, 481) of births. Hospitals that did not stock PGE had less annual births and were located a further distance from a center that provided pediatric cardiac surgical services. Patients born at a hospital that did not stock PGE had significantly greater serum lactate and creatinine (p = 0.002) and serum lactate on admission (p < 0.001). The PGE availability was not associated with hospital length of stay, postoperative length of stay, or mortality. When stratifying in TGA and HLHS subgroups, lack of PGE availability remained associated with higher creatinine, higher lactate, lower glucose, and lower pH. PGE is not universally available in all healthcare institutions providing obstetrical services. Lack of availability of PGE at an outlying hospital was associated with increased morbidity, but was not associated with mortality or length of stay.
