Relation between Body Iron Store and Insulin Resistance in Type 2 Diabetes

تم التحري عن التداخلات السريرية لحالة الحديد في الجسم والتي تشمل (حديد مصل الدم والحديد المخزون في الفيريتين) عند مرضى داء السكري غير المعتمد على الانسولين(النوع 2 ) . شملت الدراسة  36  انثى ، من الاناث  18 مصابة بداء السكري ( النوع 2) و  18 انثى من الاصحاء . كانت المجموعتين متقاربتين بالعمر وفي مؤشر كتلة الجسم (BMI ). اما مجموعة المريضات فقد كانت متماثلة فيما بينها من حيث العمر ومؤشر كتلة الجسم والعلاجات الفموية الخافضة للسكر(مثل الكلبنكلامايد والميتفورمين )ومضاعفات داء السكر. تم قياس الدوال الكيموحيوية لمجموعتي الاصحاء والمرضى وقد شملت :- الانسولين, الكلوكوز بعد الصيام, الحديد في مصل الدم والفيريتين. لوحظت زيادة معنوية عالية في جميع هذه الدوال عند المرضى مقارنة  بالاصحاء. وقد كانت هذه الزيادة واضحة في مقاومة الانسولين (IR ) والتي تم حسابها حسب المعادلة :-   IR = (الانسولين µIU/ ml ×  الكلوكوز mmol/ L) / 22.5   حيث وجدت (275.9 ± 22.7 ) مقارنة بالاصحاء (41.5 ± 11.3 )The clinical impact of interaction between body iron status (serum iron and ferritin ) and type 2  diabetes  has been investigated in this study . Thirty six females were enrolled, eighteen type 2 diabetes and eighteen apparently healthy. These two groups were matched for age and body mass index BMI. The eighteen diabetes females were matched for age, BMI, pharmacological treatment (oral hypoglycemic agent), and chronic diabetes complications . The biochemical parameters measured for both groups (control and diabetes patient) were fasting insulin(Io),fasting  blood glucose (Go) , serum iron and ferritin .  A significant increase in all parameters in patients compared to healthy control was noticed . The insulin resistance ( IR) which was calculated by the equation:-            IR= (Io µIU/ ml × Go mmol/ L)/22.5 was clearly demonstrated to be significantly higher in female diabetes patient( 275.9 ± 22.7) compared to control (41.5±11.3) . &nbsp

The Socio-Demographic Characteristics Associated with Non-Communicable Diseases among the Adult Population of Dubai: Results from Dubai Household Survey 2019.

BACKGROUND: Non-communicable diseases (NCDs) are the leading causes of death worldwide. In the UAE, NCDs account for nearly 77% of all deaths. There is limited empirical research on this topic in the UAE. We aimed to examine the association of non-communicable diseases and the sociodemographic characteristics among the adult population of Dubai. METHODS: The study used secondary data from the Dubai Household Health Survey (DHHS), 2019. DHHS is a cross-sectional complex design, stratified by geographic area, and uses multistage probability sampling. In this survey, 2247 families were interviewed and only adults aged 18+ were included for the analysis. The quasi-binomial distribution was used to identify the socio-demographic characteristics association with NCDs. RESULTS: The prevalence of NCDs among the adult population of Dubai was 15.01%. Individuals aged 60+, local Arabs (Emirati), divorced and widowed individuals, and individuals who were not currently working reported NCDs more than the other groups. In the regression analysis, the association with NCDs were reported among elderly people, males, unmarried individuals, older individuals who are unmarried, and Emiratis. CONCLUSION: The study identified several socio-demographic characteristics associated with reporting NCDs. This is one of the few studies related to NCDs in Dubai. Allocating appropriate resources to the population groups identified is crucial to reduce the incidence of NCDs in the Emirate

Evaluation of a quality improvement intervention to reduce anastomotic leak following right colectomy (EAGLE): pragmatic, batched stepped-wedge, cluster-randomized trial in 64 countries

Background: Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. Methods: The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. Results: A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). Conclusion: Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)

The sociodemographic determinants of non-communicable diseases among the adult population of Dubai: self-reported data from Dubai household health survey, 2019

Abstract Background: Non-communicable diseases (NCDs) are the leading causes of death worldwide. In the UAE, NCDs account for nearly 77% of all deaths. There is limited empirical research on this topic in the UAE. We aim to examine this association among the adult population in the Emirate of Dubai.Method: This study used data from the Dubai Household Health Survey (DHHS), 2019. In this survey, 2,247 families were interviewed and only adults aged 18+ were included for the analysis. The self-reported chronic disease was defined as reporting any chronic morbidities occurred during the past year that required ongoing medical attention and medical care. Sociodemographic characteristics covariates were age group, marital status, nationality, gender, education and working status. The quasi-binomial distribution was used to identify factors associated with chronic disease.Results: The prevalence of chronic diseases among the adult population of Dubai was 15.01%. Individuals aged 60+, local Arabs (Emirati), divorced and widowed individuals, and individuals who were not currently working reported a chronic disease more than the other groups. In the regression analysis, age (years) was the strongest predictor (OR 3.6, 95% CI: 2.8, 4.7). Males were more likely to report a chronic disease (OR 1.61, 95% CI: 1.277, 2.035). Unmarried individuals were less likely to report a chronic disease (OR 0.11, 95% CI: 0.02, 0.70). However, older individuals who were unmarried were more likely to report a chronic disease compared to the reference group (OR 2.8, 95% CI: 1.2, 6.1). Emiratis were more likely to report a chronic disease (OR 2.08, 95% CI: 1.62, 2.67).Conclusion: The self-reported rate of chronic disease was shown to be higher in older individuals, males, Emiratis, and older individuals who were unmarried. This is one of the few studies related to chronic diseases in Dubai. It is important to translate the current study findings into policies to help reduce the incidence of chronic diseases in Dubai and to minimize the negative impact of these illnesses, particularly among those with the sociodemographic risk factors identified here. In addition, healthcare services and resources should be reallocated to the population groups with greater health needs.</jats:p

Experiment realization and simulation of new vertical rotating disk of eddy current separator Realizacja eksperymentu i symulacja nowej pionowej tarczy obrotowej separatora wiroprądowego

The eddy current separation is an efficient and simple technique to recover conducting particles without contact and doesn’t need water in the separation process. There are several types of eddy current separators in industry that can be classified according to different characteristics: kind of separates particles, orientation: horizontal and vertical, magnetic field magnitude: high gradient and intensities, and other criteria. The aim of this paper is to concept eddy current separator prototype of rotational vertical disc with a new improved concept of strong permanent magnet distributions of 8 poles. This kind of separator uses spiral or big permanent magnets with few numbers, but our devise is characterized by an important number of strong permanent magnets on the surface of vertical disk to produce an important magnetic field and strong ejection force. The eddy current separator is modeled and simulated with finite element method to show the magnetic flux density near the dynamic separator and to compute the induced current and Lorentz force on two different natures of non-ferrous particles. The experiments separation results by this new prototype help to recovery non-ferrous particles from mixture waste using ejection magnetic force with a rate of 100%. Moreover, the device was developed to sort and purify the non-ferrous particles with maximum separation rate and important ejection distance. The proposed simulation and experiment results can be used to improve several separator parameters
