Since The Start Of The Vaccines For Children Program, Uptake Has Increased, And Most Disparities Have Decreased

The Vaccines for Children program is a US government intervention aimed at increasing vaccination uptake by removing financial barriers that may prevent US children from accessing vaccinations. This study examined the impact that this intervention had on race and ethnicity–related and income-related disparities for diphtheria-tetanus-acellular pertussis, measles-mumps-rubella, and polio vaccinations, using data from the National Immunization Survey, 1995–2013. Vaccination rates increased across all races, ethnicities, and income groups following the introduction of the Vaccines for Children program. Disparities among race and ethnic groups narrowed considerably over time since the introduction of the vaccine program, although income-related disparities changed at different rates within racial and ethnic groups and in some cases increased. Government interventions aimed solely at reducing certain financial barriers to vaccination may fail to address other important aspects of cost or perceived benefits that influence vaccination uptake, especially among poorer children

Glycemic Control Patterns and Kidney Disease Progression among Primary Care Patients with Diabetes Mellitus

Background: Reducing glycosylated hemoglobin (HbA1c) to near or less than 7% in patients with diabetes is associated with diminished microvascular complications, but this level is not consistently achieved. The purpose of this study was to examine the relationship between fluctuations in HbA1c and changes in estimated glomerular filtration rate (eGFR) and estimated stage of chronic kidney disease (CKD) in an academic primary care practice. Methods: We analyzed data from 791 diabetic primary care patients (25% white; 75% African American) enrolled between 1998 to 2002 and followed through 2008 (mean follow-up, 7.6 1.9 years). We calculated baseline and final follow-up eGFR using the Modification of Diet in Renal Disease equation. We examined the relationship between fluctuations in HbA1c and changes in eGFR and stage of CKD using multivariable linear and logistic regression models that controlled for demographic and clinical variables associated with CKD progression. Results: From baseline to follow-up, mean eGFR in African Americans declined to a greater extent and more rapidly than in whites. Age, mean systolic blood pressure, initial HbA1c, initial eGFR, and number of HbA1c values (all P 7% (P < .02); however, this contributed little to explaining model variance. Conclusion: These data suggest that traditional demographic and clinical risk factors remain significantly associated with changes in eGFR and that the pattern of variability in HbA1c is only modestly important in contributing to changes in eGFR among African-American and white diabetic patients in primary care

Ethno-Religious Conflict In Northern Ireland

The Troubles, is an ethno-religious conflict within Northern Ireland that occurred from 1968 to 1998. During this conflict, the constitutional status of Northern Ireland was questioned—will it remain with the United Kingdom or finally become a united Ireland? Many scholars in political science discuss the roots of this conflict as an ethnic divide, citing anti-Irish discrimination and the perpetuation of ethnic stereotypes for centuries. However, scholars within this field fail to acknowledge the strong religious identities and anti-Catholicism. Without divulging and understanding each identities’ religious beliefs, scholars fail to understand how each identity sees not only themselves, but also others. I argue that the Troubles is not an ethno-national conflict, but an ethno-religious conflict that promoted two extreme forms of nationalism--the same pattern that has been present for centuries. The presence of paramilitary groups and discrimination within the political system divided these two groups even further. The Good Friday Agreement in 1998 led to the official end of the conflict, and promoted peace and stability in Northern Ireland. With the recent controversy of the United Kingdom leaving the European Union, the question of Northern Ireland’s constitutional status is back on the table

Eosinophil and T Cell Markers Predict Functional Decline in COPD Patients

BACKGROUND. The major marker utilized to monitor COPD patients is forced expiratory volume in one second (FEV1). However, asingle measurement of FEV1 cannot reliably predict subsequent decline. Recent studies indicate that T lymphocytes and eosinophils are important determinants of disease stability in COPD. We therefore measured cytokine levels in the lung lavage fluid and plasma of COPD patients in order to determine if the levels of T cell or eosinophil related cytokines were predictive of the future course of the disease. METHODS. Baseline lung lavage and plasma samples were collected from COPD subjects with moderately severe airway obstruction and emphysematous changes on chest CT. The study participants were former smokers who had not had a disease exacerbation within the past six months or used steroids within the past two months. Those subjects who demonstrated stable disease over the following six months (ΔFEV1 % predicted = 4.7 ± 7.2; N = 34) were retrospectively compared with study participants who experienced a rapid decline in lung function (ΔFEV1 % predicted = -16.0 ± 6.0; N = 16) during the same time period and with normal controls (N = 11). Plasma and lung lavage cytokines were measured from clinical samples using the Luminex multiplex kit which enabled the simultaneous measurement of several T cell and eosinophil related cytokines. RESULTS AND DISCUSSION. Stable COPD participants had significantly higher plasma IL-2 levels compared to participants with rapidly progressive COPD (p = 0.04). In contrast, plasma eotaxin-1 levels were significantly lower in stable COPD subjects compared to normal controls (p < 0.03). In addition, lung lavage eotaxin-1 levels were significantly higher in rapidly progressive COPD participants compared to both normal controls (p < 0.02) and stable COPD participants (p < 0.05). CONCLUSION. These findings indicate that IL-2 and eotaxin-1 levels may be important markers of disease stability in advanced emphysema patients. Prospective studies will need to confirm whether measuring IL-2 or eotaxin-1 can identify patients at risk for rapid disease progression.National Heart, Lung, and Blood Institute (NO1-HR-96140, NO1-HR-96141-001, NO1-HR-96144, NO1-HR-96143; NO1-HR-96145; NO1-HR-96142, R01HL086936-03); The Flight Attendant Medical Research Institute; the Jo-Ann F.

Height and timing of growth spurt during puberty in young people living with vertically acquired HIV in Europe and Thailand.

OBJECTIVE: The aim of this study was to describe growth during puberty in young people with vertically acquired HIV. DESIGN: Pooled data from 12 paediatric HIV cohorts in Europe and Thailand. METHODS: One thousand and ninety-four children initiating a nonnucleoside reverse transcriptase inhibitor or boosted protease inhibitor based regimen aged 1-10 years were included. Super Imposition by Translation And Rotation (SITAR) models described growth from age 8 years using three parameters (average height, timing and shape of the growth spurt), dependent on age and height-for-age z-score (HAZ) (WHO references) at antiretroviral therapy (ART) initiation. Multivariate regression explored characteristics associated with these three parameters. RESULTS: At ART initiation, median age and HAZ was 6.4 [interquartile range (IQR): 2.8, 9.0] years and -1.2 (IQR: -2.3 to -0.2), respectively. Median follow-up was 9.1 (IQR: 6.9, 11.4) years. In girls, older age and lower HAZ at ART initiation were independently associated with a growth spurt which occurred 0.41 (95% confidence interval 0.20-0.62) years later in children starting ART age 6 to 10 years compared with 1 to 2 years and 1.50 (1.21-1.78) years later in those starting with HAZ less than -3 compared with HAZ at least -1. Later growth spurts in girls resulted in continued height growth into later adolescence. In boys starting ART with HAZ less than -1, growth spurts were later in children starting ART in the oldest age group, but for HAZ at least -1, there was no association with age. Girls and boys who initiated ART with HAZ at least -1 maintained a similar height to the WHO reference mean. CONCLUSION: Stunting at ART initiation was associated with later growth spurts in girls. Children with HAZ at least -1 at ART initiation grew in height at the level expected in HIV negative children of a comparable age

Observation of associated near-side and away-side long-range correlations in √sNN=5.02 TeV proton-lead collisions with the ATLAS detector

Two-particle correlations in relative azimuthal angle (Δϕ) and pseudorapidity (Δη) are measured in √sNN=5.02  TeV p+Pb collisions using the ATLAS detector at the LHC. The measurements are performed using approximately 1  μb-1 of data as a function of transverse momentum (pT) and the transverse energy (ΣETPb) summed over 3.1<η<4.9 in the direction of the Pb beam. The correlation function, constructed from charged particles, exhibits a long-range (2<|Δη|<5) “near-side” (Δϕ∼0) correlation that grows rapidly with increasing ΣETPb. A long-range “away-side” (Δϕ∼π) correlation, obtained by subtracting the expected contributions from recoiling dijets and other sources estimated using events with small ΣETPb, is found to match the near-side correlation in magnitude, shape (in Δη and Δϕ) and ΣETPb dependence. The resultant Δϕ correlation is approximately symmetric about π/2, and is consistent with a dominant cos⁡2Δϕ modulation for all ΣETPb ranges and particle pT

Search for direct pair production of the top squark in all-hadronic final states in proton-proton collisions at s√=8 TeV with the ATLAS detector

The results of a search for direct pair production of the scalar partner to the top quark using an integrated luminosity of 20.1fb−1 of proton–proton collision data at √s = 8 TeV recorded with the ATLAS detector at the LHC are reported. The top squark is assumed to decay via t˜→tχ˜01 or t˜→ bχ˜±1 →bW(∗)χ˜01 , where χ˜01 (χ˜±1 ) denotes the lightest neutralino (chargino) in supersymmetric models. The search targets a fully-hadronic final state in events with four or more jets and large missing transverse momentum. No significant excess over the Standard Model background prediction is observed, and exclusion limits are reported in terms of the top squark and neutralino masses and as a function of the branching fraction of t˜ → tχ˜01 . For a branching fraction of 100%, top squark masses in the range 270–645 GeV are excluded for χ˜01 masses below 30 GeV. For a branching fraction of 50% to either t˜ → tχ˜01 or t˜ → bχ˜±1 , and assuming the χ˜±1 mass to be twice the χ˜01 mass, top squark masses in the range 250–550 GeV are excluded for χ˜01 masses below 60 GeV

Measurement of the inclusive and dijet cross-sections of b-jets in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector

The inclusive and dijet production cross-sections have been measured for jets containing b-hadrons (b-jets) in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV, using the ATLAS detector at the LHC. The measurements use data corresponding to an integrated luminosity of 34 pb^-1. The b-jets are identified using either a lifetime-based method, where secondary decay vertices of b-hadrons in jets are reconstructed using information from the tracking detectors, or a muon-based method where the presence of a muon is used to identify semileptonic decays of b-hadrons inside jets. The inclusive b-jet cross-section is measured as a function of transverse momentum in the range 20 < pT < 400 GeV and rapidity in the range |y| < 2.1. The bbbar-dijet cross-section is measured as a function of the dijet invariant mass in the range 110 < m_jj < 760 GeV, the azimuthal angle difference between the two jets and the angular variable chi in two dijet mass regions. The results are compared with next-to-leading-order QCD predictions. Good agreement is observed between the measured cross-sections and the predictions obtained using POWHEG + Pythia. MC@NLO + Herwig shows good agreement with the measured bbbar-dijet cross-section. However, it does not reproduce the measured inclusive cross-section well, particularly for central b-jets with large transverse momenta.Comment: 10 pages plus author list (21 pages total), 8 figures, 1 table, final version published in European Physical Journal

Associations among diet, inflammation and iron status in young adults

Obesity is a risk factor for poor iron status due to the chronic, low-grade inflammation of adipose tissue hypertrophy. Among other positive acute phase proteins, the hepatic peptide hormone hepcidin is secreted during inflammation, inhibiting systemic iron efflux from enterocytes and downregulating systemic iron recycling by suppressing iron release from the mononuclear phagocyte system. Conversely, production and secretion of the iron transport protein transferrin by the liver is reduced during inflammation. In addition to increasing adiposity, certain foods are also known to promote inflammatory states and may contribute to these same effects in concert with, or independent of obesity. In this study, we evaluated how inflammatory diets are related to inflammatory and iron status biomarkers among 98 young adults with normal weight, overweight and obesity. Three-day dietary records and biomarker data for iron status and inflammation from two cross-sectional studies of similar design (Diet and Inflammation Study, n= 39 and the Selenium and Inflammation Study, n= 59) were used in this study. Dietary Inflammatory Index (DII) scores were calculated for each subject using nutrients and other dietary components from the dietary records, and subjects were further classified into two DII categories using cluster analysis. Using ANOVA we compared iron status and inflammatory markers among subjects with normal weight, overweight and obesity. We determined the association between DII scores or DII category and C-reactive protein (CRP), hepcidin, serum iron and total iron binding capacity (TIBC). Statistical significance was set at P&lt; 0.05. Mean + SEM were reported for continuous variables except for skewed variables in which case geometric means (geometric mean +1SEM interval) were reported. CRP concentration differed significantly by BMI category (p &lt; 0.05 for all comparisons) and serum iron (SI) was lower in the obese category compared to normal weight (p=0.014). Results from the regression analysis showed that high DII scores were associated with increased CRP concentration and decreasing TIBC. Similarly, subjects in the anti-inflammatory diet group showed higher TIBC compared to those in the inflammatory diet group. In conclusion, our study showed that inflammatory diets may impair iron status by reducing the capacity of the iron transport protein transferrin to transport iron in the blood
