Prevalence of Celiac in Children and Adolescents with Seizure Referring to Amir Hospital in Zabol during 2016

Introduction: Celiac is an autoimmune disease that in addition to gastrointestinal complications has extra-intestinal complications such as neurological manifestations including seizure, encephalopathy, and ataxia.  This study was conducted to determine the prevalence of celiac in children with seizure.   Materials & Methods: This descriptive cross-sectional study was performed on 100 children with seizure during 1395. Blood samples were taken from all patients to assay IgA tissue transglutaminase (IgA anti tTG). Then, all patients with elevated levels of TTgIGA were subjected to endoscopy and biopsy to confirm the diagnosis of celiac. The results were analyzed using the SPSS 21 software package and frequency distribution. Findings: In this study, 100 children and adolescents aged 2 to 18 years with seizure were studied. The average age of these patients was 16.1±1.12 years. 54% of patients had generalized tonic-clonic seizures and 46% had paroxysmal seizures. Three people with generalized tonic-clonic seizures and 2 subjects with parasitic seizures tested IgA tTg-positive. The prevalence of celiac disease among patients with seizure was 5%.   Discussion & Conclusions: Due to accompaniment of celiac with neurological manifestations, patients with neurological symptoms and gastrointestinal symptoms should be examined for celia

The Economic Burden of Coronary Heart Disease in Iran: A Bottom-up Approach in 2014

Background & objectives: cardiovascular diseases are the main cause of mortality around the whole world. However, there is limited information on its economic costs in Iran. The aim of this study was to evaluate the economic costs of coronary heart disease in Iran in 2014. Methods: The diseases costs were calculated based on the incidence approach using a bottom-up method and a community-oriented perspective.   The drug cost information was obtained from angiographed patients (607 cases) in Shahid Modarres Hospital using simple random sampling method. Other information like disease incidence, distribution of patients, treatment patterns, length of stay and mortality rate was gathered from the literature, interview with patients, consultation with specialists, questionnaire, ministry of health and statistical center of Iran. Results: Coronary heart diseases impose a significant economic burden in the range of 4,715 and 4,908 billion dollars (210,037,860,000,000-201,778,425,000,000 rials) upon Iran economic system. The medical costs and the costs of lost productivity due to premature death were calculated at USD 3.572 billion (152,863,740,000,000 rials) and USD 933 million (39,927,735,000,000 rials) respectively. The major part of medical costs was related to angioplasty costs (47%) and the minor part was related to drug costs (1.15%). Conclusion: Coronary heart diseases impose a lot of financial costs to Iran healthcare system which cover more than 16% of whole healthcare financial costs. It is possible to streamline all consequential costs due to coronary heart disease by means of economic and effective use of resources and widespread self-care plan

Chitosan/polyvinyl alcohol nanofibrous membranes: towards green super-adsorbents for toxic gases

Removal of hazardous gases from the atmosphere has become a big challenge for scientists and engineers alike. Eco-friendly nature of biopolymers has given a new dimension to the debate within the environmental science area but attempts mainly failed to cleanse the air stream of toxic gases as a consequence of design imperfections. In this work, green electrospun nanofibrous membranes based on chitosan (Cs)/polyvinyl alcohol (PVA) composite with a very high carbon monoxide adsorption capacity (much higher than the values one may expect from activated carbon and zeolite adsorbents, and also higher than that of the metal-organic framework) are developed. 2k−1 factorial design, response surface and desirability function analyses are merged to optimize the electrospinning parameters for functional-based carbon monoxide elimination. The best Cs/PVA adsorbent obtained through multi-objective optimization has a very high desirability value level of 0.953. Optimized electrospinning parameters are: Voltage = 17 kV, spinning distance = 13 cm, flow rate = 0.2 mL/h, and PVA concentration = 6 wt.%; and optimized properties are: maximum thermal stability = 329 °C, minimum fiber diameter = 9.8 nm, and maximum surface area = 2204 m2/g. This work opens a new era for taking the next steps towards the design and optimization of green super-adsorbents for gaseous contaminations

Global, regional, and national burden of diabetes from 1990 to 2021, with projections of prevalence to 2050: a systematic analysis for the Global Burden of Disease Study 2021

Background: Diabetes is one of the leading causes of death and disability worldwide, and affects people regardless of country, age group, or sex. Using the most recent evidentiary and analytical framework from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD), we produced location-specific, age-specific, and sex-specific estimates of diabetes prevalence and burden from 1990 to 2021, the proportion of type 1 and type 2 diabetes in 2021, the proportion of the type 2 diabetes burden attributable to selected risk factors, and projections of diabetes prevalence through 2050. Methods: Estimates of diabetes prevalence and burden were computed in 204 countries and territories, across 25 age groups, for males and females separately and combined; these estimates comprised lost years of healthy life, measured in disability-adjusted life-years (DALYs; defined as the sum of years of life lost [YLLs] and years lived with disability [YLDs]). We used the Cause of Death Ensemble model (CODEm) approach to estimate deaths due to diabetes, incorporating 25 666 location-years of data from vital registration and verbal autopsy reports in separate total (including both type 1 and type 2 diabetes) and type-specific models. Other forms of diabetes, including gestational and monogenic diabetes, were not explicitly modelled. Total and type 1 diabetes prevalence was estimated by use of a Bayesian meta-regression modelling tool, DisMod-MR 2.1, to analyse 1527 location-years of data from the scientific literature, survey microdata, and insurance claims; type 2 diabetes estimates were computed by subtracting type 1 diabetes from total estimates. Mortality and prevalence estimates, along with standard life expectancy and disability weights, were used to calculate YLLs, YLDs, and DALYs. When appropriate, we extrapolated estimates to a hypothetical population with a standardised age structure to allow comparison in populations with different age structures. We used the comparative risk assessment framework to estimate the risk-attributable type 2 diabetes burden for 16 risk factors falling under risk categories including environmental and occupational factors, tobacco use, high alcohol use, high body-mass index (BMI), dietary factors, and low physical activity. Using a regression framework, we forecast type 1 and type 2 diabetes prevalence through 2050 with Socio-demographic Index (SDI) and high BMI as predictors, respectively. Findings: In 2021, there were 529 million (95% uncertainty interval [UI] 500-564) people living with diabetes worldwide, and the global age-standardised total diabetes prevalence was 6·1% (5·8-6·5). At the super-region level, the highest age-standardised rates were observed in north Africa and the Middle East (9·3% [8·7-9·9]) and, at the regional level, in Oceania (12·3% [11·5-13·0]). Nationally, Qatar had the world's highest age-specific prevalence of diabetes, at 76·1% (73·1-79·5) in individuals aged 75-79 years. Total diabetes prevalence-especially among older adults-primarily reflects type 2 diabetes, which in 2021 accounted for 96·0% (95·1-96·8) of diabetes cases and 95·4% (94·9-95·9) of diabetes DALYs worldwide. In 2021, 52·2% (25·5-71·8) of global type 2 diabetes DALYs were attributable to high BMI. The contribution of high BMI to type 2 diabetes DALYs rose by 24·3% (18·5-30·4) worldwide between 1990 and 2021. By 2050, more than 1·31 billion (1·22-1·39) people are projected to have diabetes, with expected age-standardised total diabetes prevalence rates greater than 10% in two super-regions: 16·8% (16·1-17·6) in north Africa and the Middle East and 11·3% (10·8-11·9) in Latin America and Caribbean. By 2050, 89 (43·6%) of 204 countries and territories will have an age-standardised rate greater than 10%. Interpretation: Diabetes remains a substantial public health issue. Type 2 diabetes, which makes up the bulk of diabetes cases, is largely preventable and, in some cases, potentially reversible if identified and managed early in the disease course. However, all evidence indicates that diabetes prevalence is increasing worldwide, primarily due to a rise in obesity caused by multiple factors. Preventing and controlling type 2 diabetes remains an ongoing challenge. It is essential to better understand disparities in risk factor profiles and diabetes burden across populations, to inform strategies to successfully control diabetes risk factors within the context of multiple and complex drivers.
