Abstract: llergic bronchopulmonary aspergillosis treated successfully for one year with omalizumab Case Series (1686) Total Article Views Authors: Collins J, de Vos G, Hudes G, Rosenstreich D Published Date November 2012 Volume 2012:5 Pages 65 - 70 DOI: http://dx.doi.org/10.2147/JAA.S34579 Received: 02 June 2012 Accepted: 01 August 2012 Published: 08 November 2012 Jennifer Collins,1 Gabriele deVos,2 Golda Hudes,2 David Rosenstreich2 1New York Eye and Ear Infirmary, New York, NY, 2Albert Einstein College of Medicine/Montefiore Medical Center, Bronx, NY, USA Background: Current therapy for allergic bronchopulmonary aspergillosis (ABPA) uses oral corticosteroids, exposing patients to the adverse effects of these agents. There are reports of the steroid-sparing effect of anti-IgE therapy with omalizumab for ABPA in patients with cystic fibrosis (CF), but there is little information on its efficacy against ABPA in patients with bronchial asthma without CF. Objective: To examine the effects of omalizumab, measured by asthma control, blood eosinophilia, total serum immunoglobulin E (IgE), oral corticosteroid requirements, and forced expiratory volume spirometry in patients with ABPA and bronchial asthma. Methods: A retrospective review of charts from 2004–2006 of patients treated with omalizumab at an academic allergy and immunology practice in the Bronx, New York were examined for systemic steroid and rescue inhaler usage, serum immunoglobulin E levels, blood eosinophil counts, and asthma symptoms, as measured by the Asthma Control Test (ACT). Results: A total of 21 charts were screened for the diagnosis of ABPA and bronchial asthma. Four patients with ABPA were identified; two of these patients were male. The median monthly systemic corticosteroid use at 6 months and 12 months decreased from baseline usage. Total serum IgE decreased in all patients at 12 months of therapy. Pre-bronchodilator forced expiratory vital capacity at one second (FEV1) was variable at 1 year of treatment. There was an improvement in Asthma Control Test (ACT) symptom scores for both daytime and nighttime symptoms. Conclusions: Treatment with omalizumab creates a steroid-sparing effect, reduces systemic inflammatory markers, and results in improvement in ACT scores in patients with ABPA.

Gladys Block, Christopher D Jensen, Edward P Norkus, Tapashi B Dalvi, Les G Wong, Jamie F McManus, Mark L Hudes
Nutrition Journal , 2007, DOI: 10.1186/1475-2891-6-30
Abstract: Using a cross-sectional study design, information was obtained by online questionnaires and physical examination (fasting blood, blood pressure, body weight) from a convenience sample of long-term users of multiple dietary supplements manufactured by Shaklee Corporation (Multiple Supp users, n = 278). Data for non-users (No Supp users, n = 602) and multivitamin/mineral supplement users (Single Supp users, n = 176) were obtained from the National Health and Nutrition Examination Survey (NHANES) 2001–2002 and NHANES III 1988–1994. Logistic regression methods were used to estimate odds ratios with 95% confidence intervals.Dietary supplements consumed on a daily basis by more than 50% of Multiple Supp users included a multivitamin/mineral, B-complex, vitamin C, carotenoids, vitamin E, calcium with vitamin D, omega-3 fatty acids, flavonoids, lecithin, alfalfa, coenzyme Q10 with resveratrol, glucosamine, and a herbal immune supplement. The majority of women also consumed gamma linolenic acid and a probiotic supplement, whereas men also consumed zinc, garlic, saw palmetto, and a soy protein supplement. Serum nutrient concentrations generally increased with increasing dietary supplement use. After adjustment for age, gender, income, education and body mass index, greater degree of supplement use was associated with more favorable concentrations of serum homocysteine, C-reactive protein, high-density lipoprotein cholesterol, and triglycerides, as well as lower risk of prevalent elevated blood pressure and diabetes.This group of long-term multiple dietary supplement users consumed a broad array of vitamin/mineral, herbal, and condition-specific dietary supplements on a daily basis. They were more likely to have optimal concentrations of chronic disease-related biomarkers, and less likely to have suboptimal blood nutrient concentrations, elevated blood pressure, and diabetes compared to non-users and multivitamin/mineral users. These findings should be confirmed by studying th
Vitamin C in plasma is inversely related to blood pressure and change in blood pressure during the previous year in young Black and White women

Nutrition Journal , 2008, DOI: 10.1186/1475-2891-7-35
Abstract: Participants were 242 Black and White women aged 18–21 yr from the Richmond, CA, cohort of the National Heart, Lung and Blood Institute Growth and Health Study. We examined the associations of plasma ascorbic acid with BP at follow-up year 10, and with change in BP during the previous year.In cross-sectional analysis, plasma ascorbic acid at year 10 was inversely associated with systolic BP and diastolic BP after adjusting for race, body mass index, education, and dietary intake of fat and sodium. Persons in the highest one-fourth of the plasma ascorbic acid distribution had 4.66 mmHg lower systolic BP (95% CI 1.10 to 8.22 mmHg, p = 0.005) and 6.04 mmHg lower diastolic BP (95% CI 2.70 to 9.38 mmHg, p = 0.0002) than those in the lowest one-fourth of the distribution. In analysis of the change in BP, plasma ascorbic acid was also inversely associated with change in systolic BP and diastolic BP during the previous year. While diastolic blood pressure among persons in the lowest quartile of plasma ascorbic acid increased by 5.97 mmHg (95% CI 3.82 to 8.13 mmHg) from year 9 to year 10, those in the highest quartile of plasma vitamin C increased by only 0.23 mmHg (95% CI -1.90 to +2.36 mmHg) (test for linear trend: p < 0.0001). A similar effect was seen for change in systolic BP, p = 0.005.Plasma ascorbic acid was found to be inversely associated with BP and change in BP during the prior year. The findings suggest the possibility that vitamin C may influence BP in healthy young adults. Since lower BP in young adulthood may lead to lower BP and decreased incidence of age-associated vascular events in older adults, further investigation of treatment effects of vitamin C on BP regulation in young adults is warranted.Elevated blood pressure (BP) is a major public health problem in the United States with almost 60% of American adults having pre-hypertension or hypertension [1]. The disorder is prevalent in all major ethnic groups, although Blacks are disproportionately affected
Macronutrient intakes and cardio metabolic risk factors in high BMI African American children

Nutrition & Metabolism , 2009, DOI: 10.1186/1743-7075-6-41
Abstract: A cross sectional analysis of a sample of 9-11 year old children (n = 80) with BMI greater then the 85th percentile. Fasting hematological and biochemical measurements, and blood pressure were measured as selected markers of cardio metabolic risk factors and their relationships to dietary intakes determined.After adjusting for gender, pubertal stage and waist circumference (WC), multivariate regression analysis showed that higher total energy intakes (when unadjusted for source of energy) were associated with higher plasma concentrations of intermediate density lipoprotein cholesterol (IDL-C) and very low density lipoprotein cholesterol (VLDL-C). Higher intakes of carbohydrate energy (fat and protein held constant) were associated with higher IDL-C, VLDL-C, triglycerides (TG) and homeostasis model assessment of insulin resistance (HOMA-IR). Higher intakes of fat (carbohydrate and protein held constant), however, were associated with lower IDL-C; and higher protein intakes (fat and carbohydrate held constant) were associated with lower HOMA-IR.The specific macronutrients that contribute energy are significantly associated with a wide range of cardio metabolic risk factors in high BMI AA children. Increases in carbohydrate energy were associated with undesirable effects including increases in several classes of plasma lipids and HOMA-IR. Increases in protein energy were associated with the desirable effect of reduced HOMA-IR, and fat energy intakes were associated with the desirable effect of reduced IDL-C. This analysis suggests that the effect of increased energy on risk of developing cardio metabolic risk factors is influenced by the source of that energy.In the past three decades, the prevalence of overweight and obesity among youth in the USA has doubled and tripled, respectively [1]. Obesity during childhood and adolescence is associated with a number of cardiovascular disease risk factors including type 2 diabetes mellitus, hypertension, and dyslipidemia. Many

Trials , 2010, DOI: 10.1186/1745-6215-11-60
Abstract: This protocol includes the theory, development, evaluation components and lessons learned from a novel YMCA-based T2DM prevention intervention designed specifically for high-BMI African American children from disadvantaged, inner-city neighborhoods of Oakland, California. The intervention was developed on the basis of: review of epidemiological and intervention studies of pediatric T2DM; a conceptual theory (social cognitive); a comprehensive examination of health promotion curricula designed for children; consultation with research, clinical experts and practitioners and; input from community partners. The intervention, Taking Action Together, included culturally sensitive and age-appropriate programming on: healthy eating; increasing physical activity and, improving self esteem.Evaluations completed to date suggest that Taking Action Together may be an effective intervention, and results warrant an expanded evaluation effort. This protocol could be used in other community settings to reduce the risk of children developing T2DM and related health consequences.ClinicalTrials.gov NCT01039116.There is a critical need for trials to be conducted that aim to identify strategies to prevent T2DM mellitus (T2DM) in children. Associated with a tripling in obesity since 1970, T2DM in children has risen 9-10 fold [1]. Additionally, nearly 1 in 6 overweight youth has pre-diabetes [2]. African American youth are among the highest for risk of T2DM with higher rates of obesity and insulin-resistance than other ethnic groups due, in part, to being more insulin resistant [3]. Nearly 50% of African American children born in the U.S. in 2000 are expected to develop diabetes in their lifetimes [4].Taking Action Together (TAT) was a controlled community-based intervention protocol developed by researchers at U.C. Berkeley in partnership with the YMCA of the East Bay to reduce risk of T2DM among low-income, high BMI, 9-10 year old African American children through improvements in nutrien

Double Negative Left-Handed Metamaterials for Miniaturization of Rectangular Microstrip Antenna  [PDF]
G. Singh
Journal of Electromagnetic Analysis and Applications (JEMAA) , 2010, DOI: 10.4236/jemaa.2010.26044
Abstract: In this paper, I have explored a significant concept for the miniaturization of microstrip patch antenna configuration by using the double negative (DNG) left-handed Metamaterials, which have dielectric permittivity and magnetic permeability both negative, simultaneously. It is achieved through the concept of phase-compensation by thin slab consist of the double positive (DPS) material, which have dielectric permittivity and magnetic permeability both positive, simultaneously and DNG metamaterials as a substrate of the microstrip patch antenna. By combining the DNG metamaterial slab with the slab made of DPS materials form a cavity resonator whose dispersion relation is independent of the sum of thickness of the slabs filling this cavity but it depends on the ratio of their thicknesses. This cavity constitutes by DPS and DNG material is used as substrate of the microstrip antennas and the DNG material slab is behave as phase compensator.
Dynamic and Configurational Approach to the Glass Transition by Nanoscale Cooperativity  [PDF]
G. Romeo
Open Journal of Biophysics (OJBIPHY) , 2012, DOI: 10.4236/ojbiphy.2012.23012
Abstract: Here we examine the findings obtained for disaccharide/water mixtures near glass transition that involves cooperative relaxation features on kinetic by viscosity and on thermodynamic behaviour by neutron scattering. Then to address cooperative phenomena that mitigate the Debye-Waller behaviour we invoke Adam-Gibbs’ idea of a cooperative rearranging region. Neutron results suggest that the excess mean square displacement behaves as free volume and is closely connected to an elementary step of the structural relaxation. Then viscosity data evidence a breakdown of the Einstein-Debye relation, decoupling attributed to the intermolecular cooperativity.
Confidence Level Estimator of Cosmological Parameters  [PDF]
G. Sironi
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.329157
Abstract: Cosmological Models frequently suggest the existence of physical, quantities, e.g. dark energy, we cannot yet observe and measure directly. Their values are obtained indirectly setting them equal to values and accuracy of the associated model parameters which best fit model and observation. Apparently results are so accurate that some researchers speak of precision cosmology. The accuracy attributed to these indirect values of the physical quantities however does not include the uncertainty of the model used to get them. We suggest a Confidence Level Estimator to be attached to these indirect measurements and apply it to current cosmological models.
