Essential Health Benefits And The Affordable Care Act: Law And Process, Nicholas Bagley, Helen Levy

Articles

Starting in 2014, the Affordable Care Act (ACA) will require private insurance plans sold in the individual and small-group markets to cover a roster of "essential health benefits." Precisely which benefits should count as essential, however, was left to the discretion of the Department of Health and Human Services (HHS). The matter was both important and controversial. Nonetheless, HHS announced its policy by posting on the Internet a thirteen-page bulletin stating that it would allow each state to define essential benefits for itself. On both substance and procedure, the move was surprising. The state-by-state approach departed from the uniform, federal …

Btk Regulated Macrophage Polarization In Response To Lipopolysaccharide, Joan Ní Gabhann, Emily Hams, Siobhán Smith, Claire Wynne, Jennifer C. Byrne, Kiva Brennan, Shaun Spence, Adrien Kissenpfennig

Articles

Bacterial Lipopolysaccharide (LPS) is a strong inducer of inflammation and does so by inducing polarization of macrophages to the classic inflammatory M1 population. Given the role of Btk as a critical signal transducer downstream of TLR4, we investigated its role in M1/M2 induction. In Btk deficient (Btk^−\−) mice we observed markedly reduced recruitment of M1 macrophages following intraperitoneal administration of LPS. Ex vivo analysis demonstrated an impaired ability of Btk^−/− macrophages to polarize into M1 macrophages, instead showing enhanced induction of immunosuppressive M2-associated markers in response to M1 polarizing stimuli, a finding accompanied by reduced phosphorylation …

Ethnic Variation In Breastfeeding And Complementary Feeding In The Republic Of Ireland, Patricia Castro, Richard Layte, John Kearney

Articles

Early nutrition plays a pivotal role in long-term health. The World Health Organization (WHO) recommends exclusive breastfeeding during the first six months of life, with the gradual introduction of solids after this period. However, studies in the Republic of Ireland (ROI) have shown poor compliance with guidelines. The ROI continues to have one of the lowest breastfeeding rates worldwide. Our objective was to analyse differences in breastfeeding and complimentary feeding behaviours between Irish and non-Irish mothers residing in the ROI, as well as the role of acculturation on these behaviours, using the national longitudinal study, Growing Up in Ireland (GUI). …

Size Dependent Translocation And Fetal Accumulation Of Gold Nanoparticles From Maternal Blood In The Rat, Manuela Semmler-Behnke, Jens Lipka, Alexander Wenk, Martin Schaeffer, Furong Tian, Gunter Schmid, Gunter Oberdorster, Wolfgang Kreyling

Articles

There is evidence that nanoparticles (NP) cross epithelial and endothelial body barriers. We hypothesized that gold (Au) NP, once in the blood circulation of pregnant rats, will cross the placental barrier during pregnancy size-dependently and accumulate in the fetal organism by 1. transcellular transport across the hemochorial placenta, 2. transcellular transport across amniotic membranes 3. transport through ~20 nm wide transtrophoblastic channels in a size dependent manner. The three AuNP sizes used to test this hypothesis are either well below, or of similar size or well above the diameters of the transtrophoblastic channels.

Disability, Repressive Regimes, And Health Disparity: Assessing Country Conditions In North Korea, Jae-Chun Won, Janet E. Lord, Michael Ashley Stein, Yosung Song

Articles

This article examines the potential of international human rights standards to account for heightened risk and vulnerability to human rights abuses for persons with disabilities in politically repressive environments. We offer a preliminary assessment of whether and how a disability-cognizant accounting of human rights in repressive regimes can lead to a more credible and comprehensive understanding of disability in such contexts. In so doing, we make the case for a more thorough and thoughtful application of international disability rights standards to better inform human rights investigations, transitional justice approaches, and international criminal law proceedings. To illustrate this methodology, we analyze …

Apple Pomace As A Potential Ingredient For The Development Of New Functional Foods, Sofia Reis, Dilip K. Rai, Nissreen Abu-Ghannam

Articles

Extruded snacks and baked scones were formulated with increasing levels (0-30%) of apple pomace (AP). The incorporation of up to 20% of AP in extruded snacks and in baked scones does not change significantly (pβ-carotene/linoleic acid system) increased when compared to the products to which no AP was added. Chlorogenic acid and quercetin were the major phenolic compounds found in the products. Loss of phenolic compounds during heat treatment occurred, however the DPPH radical scavenging activity of final products was not affected.

Development Of A Novel Functional Soup Rich In Bioactive Sulforaphane Using Broccoli (Brassica Oleracea L. Ssp. Italica) Florets And Byproducts., Laura Alvarez Jubete, Juan Valverde, Kate Kehoe, Kim Reilly, Dilip K. Rai, Catherine Barry-Ryan

Articles

Broccoli florets are rich in health-promoting compounds such as glucoraphanin, the precursor of the bioactive compound sulforaphane. In addition, broccoli byproducts such as broccoli stalk also contain health promoting compounds and represent attractive ingredients in the development of functional foods. The bioconversion of glucosinolates into bioactive isothiocyanates is affected by many factors including heat and therefore cooking of Brassicas such as broccoli may result in significant loss of sulforaphane production. The aim of this study was to develop a suitable food system as a vehicle for the delivery of sulforaphane in the human diet in adequate quantities. To this end, …

Socioeconomic Differentials In The Immediate Mortality Effects Of The National Irish Smoking Ban, Patrick J. Goodman, Sericea Stallings-Smith, Ariana Zeka, Z. Kabir, Luke Clancy

Articles

Background: Consistent evidence has demonstrated that smoking ban policies save lives, but impacts on health inequalities are uncertain as few studies have assessed post-ban effects by socioeconomic status (SES) and findings have been inconsistent. The aim of this study was to assess the effects of the national Irish smoking ban on ischemic heart disease (IHD), stroke, and chronic obstructive pulmonary disease (COPD) mortality by discrete and composite SES indicators to determine impacts on inequalities. Methods: Census data were used to assign frequencies of structural and material SES indicators to 34 local authorities across Ireland with a 2000–2010 study period. Discrete …

Economic Valuation Of The Mortality Benefits Of A Regulation On So2 In 20 European Cities, Olivier Chanel, Susann Henschel, Patrick J. Goodman, Antonis Analitis, Richard W. Atkinson, Alain Le Tertre, Ariana Zeka, Sylivia Medina

Articles

Background: Since the 1970s, legislation has led to progress in tackling several air pollutants. We quantify the annual monetary benefits resulting from reductions in mortality from the year 2000 onwards following the implementation of three European Commission regulations to reduce the sulphur content in liquid fuels for vehicles. Methods: We first compute premature deaths attributable to these implementations for 20 European cities in the Aphekom project by using a two-stage health impact assessment method. We then justify our choice to only consider mortality effects as short-term effects. We rely on European studies when selecting the central value of …

Proteomic Profiling Of Burkholderia Cenocepacia Clonal Isolates With Different Virulence Potential Retrieved From A Cystic Fibrosis Patient During Chronic Lung Infection., Siobhan Mcclean, Máire Callaghan, Jean Tyrrell, Isabelle Sa Correia

Articles

Respiratory infections with Burkholderia cepacia complex (Bcc) bacteria in cystic fibrosis (CF) are associated with a worse prognosis and increased risk of death. In this work, we assessed the virulence potential of three B. cenocepacia clonal isolates obtained from a CF patient between the onset of infection (isolate IST439) and before death with cepacia syndrome 3.5 years later (isolate IST4113 followed by IST4134), based on their ability to invade epithelial cells and compromise epithelial monolayer integrity. The two clonal isolates retrieved during late-stage disease were significantly more virulent than IST439. Proteomic profiling by 2-D DIGE of the last isolate recovered …

Mutational Analysis Of Sse1 (Hsp110) Suggests An Integral Role For This Chaperone In Yeast Prion Propagation In Vivo, Ciara Moran, Gemma Kinsella, Zai-Rong Zhang, Sarah Perrett, Gary Jones

Articles

ABSTRACT The yeast Hsp110 chaperone Sse1 is a conserved protein that is a noncanonical member of the Hsp70 protein superfamily. Sse1 influences the cellular response to heat stress and has also been implicated in playing a role in the propagation of prions in yeast. Sse1 can seemingly exert its effects in vivo through direct or indirect actions by influencing the nucleotide exchange activity of canonical cytosolic Hsp70s. Using a genetic screen based on the inability to propagate the yeast [PSI+] prion, we have identified 13 new Sse1 mutants that are predicted to alter chaperone function through a variety of different …

Enhancement Of The Phytochemical And Fibre Content Of Beef-Patties With Himanthalia Elongata Seaweed, Sabrina Cox, Nissreen Abu-Ghannam

Articles

The effect of adding Himanthalia elongata seaweed (10 - 40% w/w) as a source of antioxidants and dietary fibre on physical, chemical, microbial and sensory traits of cooked beef patties was studied throughout chilled storage. Patties with seaweed showed reduced cooking losses and were nearly 50% more tender as compared to patties without seaweed. Microbiological counts and lipid oxidation were significantly lower in patties containing seaweed (P < 0.05), by day 30 of storage there was no bacterial growth in samples with ≥ 20% seaweed and lipid oxidation levels were low (0.61 mg malondialdehyde/kg of sample). Seaweed incorporation significantly increased the dietary fibre (1.64 g per 100 g fw in 40% seaweed-patties), total phenolic content (up to 28.11 mg GAE/100 g fw) and DPPH radical scavenging activity (up to 52.32%) of patties compared to the control. Sensory analysis indicated that the seaweed-patties were accepted by consumers in terms of aroma, appearance, texture and taste. Patties containing 40% seaweed were rated highest in terms of overall acceptability, most likely due to improvement in texture and mouthfeel. Addition of seaweed in the formulation of beef patties leads to the enhancement of the nutritional and technological quality together with an acceptable sensory quality.

Incorporation Of Himanthalia Elongata Seaweed To Enhance The Phytochemical Content Of Breadsticks Using Response Surface Methodology (Rsm), Sabrina Cox, Nissreen Abu-Ghannam

Articles

Optimization of incorporating seaweed into breadsticks was carried out using response surface methodology (RSM). Ten formulations of breadsticks were processed by varying concentrations of seaweed (X₁ = 5 to 15% of overall flour concentration) and white flour (X₂ = 10 to 30% of overall flour concentration) using a central composite design. The remaining flour concentrations were comprised of wholemeal flour. Predicted models were found to be significant (P < 0.05) for total phenolic content (TPC), DPPH radical scavenging activity, texture and color. Predicted values for each of the responses were in good agreement with the experimental values. Seaweed concentration had most significant effect on phytochemical constituents of the breadsticks with TPC and DPPH activity maximized when 17.07% H. elongata was incorporated into the flour (P < 0.05). An acceptable edible texture and color of breadsticks was also achieved at this concentration. Multiple response optimization demonstrated that phytochemical content of H. elongata breadsticks may be maximized with dried seaweed and white flour concentrations of 17.07 and 21.89%, respectively, in the …

Raman Spectroscopic Analysis Of Human Skin Tissue Sections Ex-Vivo: Evaluation Of The Effects Of Tissue Processing And Dewaxing, Syed Mehmood Ali, Franck Bonnier, Ali Tfayli, Helen Lambkin, Kathleen Flynn, Vincent Mcdonagh, Claragh Healy, Thomas Lee, Fiona Lyng, Hugh Byrne

Articles

Raman spectroscopy coupled with K-means clustering analysis (KMCA) is employed to elucidate the biochemical structure of human skin tissue sections, and the effects of tissue processing. Both hand and thigh sections of human cadavers were analysed in their unprocessed and formalin fixed paraffin processed (FFPP) and subsequently dewaxed forms. In unprocessed sections, KMCA reveals clear differentiation of the stratum corneum, intermediate underlying epithelium and dermal layers for sections from both anatomical sites. The stratum corneum is seen to be relatively rich in lipidic content; the spectrum of the subjacent layers is strongly influenced by the presence of melanin, while that …

Protein Kinase C Delta Is A Substrate Of Tissue Transglutaminase And A Novel Autoantigen In Coeliac Disease, Greg Byrne, Michael Freeley, Con Feighery, Alex Whelan, Aideen Long

Articles

Post-translational modification of proteins by deamidation or transamidation by tissue transglutaminase (tTG) has been suggested as a possible mechanism for the development of autoimmunity. Sequence analysis of protein kinase C delta (PKCδ) identified an amino acid motif that suggested the possibility that PKCδ was a glutamine substrate of tTG and MALDI-TOF analysis of synthesised peptides from PKCδ proved that this was the case. Polymerisation experiments using recombinant tTG and biotinylated hexapeptide substrate incorporation assays demonstrated that PKCδ is a substrate for tTG-mediated transamidation. Elevated levels of anti-PKCδ antibodies were detected in sera from patients with coeliac disease (pb0.0001) but not …
