Health in Mind: Improving Education Through Wellness

Educators know that healthy students are better prepared to learn and succeed in school. It's also known that people who are better educated and obtain a college education have lower rates of health conditions and longer life expectancy. Yet current health and education policy misses several simple but vital opportunities to boost academic success through health promotion and school wellness. The nation's current generation of students could become the first to live shorter and less healthy lives than their parents. At the same time, our nation faces a growing achievement gap: Students who attend school in communities with lower socioeconomic status have lower academic outcomes than students in higher socioeconomic status communities. Overwhelmingly, the underserved communities predominantly comprise ethnic minority residents, which propagates a racial chasm. Research is increasingly confirming a link between the achievement gap and health disparities. For this reason, Healthy Schools Campaign and Trust for America's Health developed "Health in Mind: Improving Education Through Wellness". This effort focuses on policy recommendations for immediate, practical changes at the federal level to help close the achievement gap and create a healthy future for all children

Prolyl hydroxylase-1 regulates hepatocyte apoptosis in an NF-kB-dependent manner

Hepatocyte death is an important contributing factor in a number of diseases of the liver. PHD1 confers hypoxic sensitivity upon transcription factors including the hypoxia inducible factor (HIF) and nuclear factor-kappaB (NF-κB). Reduced PHD1 activity is linked to decreased apoptosis. Here, we investigated the underlying mechanism(s) in hepatocytes. Basal NF-κB activity was elevated in PHD1(-/-) hepatocytes compared to wild type controls. ChIP-seq analysis confirmed enhanced binding of NF-κB to chromatin in regions proximal to the promoters of genes involved in the regulation of apoptosis. Inhibition of NF-κB (but not knock-out of HIF-1 or HIF-2) reversed the anti-apoptotic effects of pharmacologic hydroxylase inhibition. We hypothesize that PHD1 inhibition leads to altered expression of NF-κB-dependent genes resulting in reduced apoptosis. This study provides new information relating to the possible mechanism of therapeutic action of hydroxylase inhibitors that has been reported in pre-clinical models of intestinal and hepatic disease.status: publishe

Standardized postnatal management of infants with congenital diaphragmatic hernia in Europe: The CDH EURO Consortium Consensus - 2015 Update

In 2010, the congenital diaphragmatic hernia (CDH) EURO Consortium published a standardized neonatal treatment protocol. Five years later, the number of participating centers has been raised from 13 to 22. In this article the relevant literature is updated, and consensus has been reached between the members of the CDH EURO Consortium. Key updated recommendations are: (1) planned delivery after a gestational age of 39 weeks in a high-volume tertiary center; (2) neuromuscular blocking agents to be avoided during initial treatment in the delivery room; (3) adapt treatment to reach a preductal saturation of between 80 and 95% and postductal saturation >70%; (4) target PaCO2 to be between 50 and 70 mm Hg; (5) conventional mechanical ventilation to be the optimal initial ventilation strategy, and (6) intravenous sildenafil to be considered in CDH patients with severe pulmonary hypertension. This article represents the current opinion of all consortium members in Europe for the optimal neonatal treatment of CDH

Increasing quasiconcave co-radiant functions with applications in mathematical economics

We study increasing quasiconcave functions which are co-radiant. Such functions have frequently been employed in microeconomic analysis. The study is carried out in the contemporary framework of abstract convexity and abstract concavity. Various properties of these functions are derived. In particular we identify a small "natural" infimal generator of the set of all coradiant quasiconcave increasing functions. We use this generator to examine two duality schemes for these functions: classical duality often used in microeconomic analysis and a more recent duality concept. Some possible applications to the theory of production functions and utility functions are discussed. © Springer-Verlag 2005.C

Early Postnatal Administration of Growth Hormone Increases Tuberoinfundibular Dopaminergic Neuron Numbers in Ames Dwarf Mice

Hypothalamic tuberoinfundibular dopaminergic (TIDA) neurons secrete dopamine, which inhibits pituitary prolactin (PRL) secretion. PRL has demonstrated neurotrophic effects on TIDA neuron development in PRL-, GH-, and TSH-deficient Ames (df/df) and Snell (dw/dw) dwarf mice. However, both PRL and PRL receptor knockout mice exhibit normal-sized TIDA neuron numbers, implying GH and/or TSH influence TIDA neuron development. The current study investigated the effect of porcine (p) GH on TIDA neuron development in Ames dwarf hypothalamus. Normal (DF/df) and dwarf mice were treated daily with pGH or saline beginning at 3 d of age for a period of 42 d. After treatment, brains were analyzed using catecholamine histofluorescence, tyrosine hydroxylase immunocytochemistry, and bromodeoxyuridine (BrdU) immunocytochemistry to detect BrdU incorporation. DF/df males and df/df treated with pGH experienced increased (P ≤ 0.01) weight gain compared with those treated with saline. DF/df had greater (P ≤ 0.01) TIDA neuron numbers than df/df, regardless of treatment. TIDA neuron number in pGH-treated df/df was greater (P ≤ 0.01) than in saline-treated df/df. Zona incerta and periventricular dopamine neurons were not affected by treatment or genotype. There was no effect of genotype or treatment on BrdU incorporation in the arcuate nucleus, median eminence, or periventricular region surrounding the third ventricle. Saline-treated df/df experienced decreased (P ≤ 0.05) dentate gyrus BrdU incorporation compared with saline-treated DF/df. In the lateral ventricle, pGH-treated males had greater BrdU immunoreactivity than pGH-treated females. The results show an effect of pGH on TIDA neuron development, although this effect is less potent than that of PRL, and likely GH-induced preservation of TIDA neurons rather than generation of new TIDA neurons via neurogenesis

Targeting Staphylococcus aureus quorum sensing with non-peptidic small molecule inhibitors

A series of 3-oxo-C12-HSL, tetramic acid and tetronic acid analogues was synthesized to gain insights into the structural requirements for quorum sensing inhibition in Staphylococcus aureus. Compounds active against agr were non-competitive inhibitors of the auto-inducing peptide (AIP)-activated AgrC receptor, by altering the activation efficacy of the cognate AIP-1. They appeared to act as negative allosteric modulators and are exemplified by 3-tetradecanoyltetronic acid 17 which reduced nasal cell colonization and arthritis in a murine infection model
