The prevalence, epidemiological characteristics and mortality trends of inflammatory myopathies patients in Oman: the Prevision study.

OBJECTIVES: This research aims to investigate the prevalence, epidemiological characteristics, mortality rates, survival rates and the rate of malignancy in patients diagnosed with inflammatory myopathies (IIM) in Oman. METHODS: This is a longitudinal study, that covered a span of 16 years at eight rheumatology centres in Oman. The study included all adults and paediatric patients diagnosed with different types of idiopathic inflammatory myopathies (IIM) and who fulfil either the Bohan classification criteria or the 2017 EULAR/ACR classification criteria. RESULTS: The study included a total of 116 patient with an average age of 38.78 (±17.61 SD) years. The most prevalent form of myositis was found to be dermatomyositis (DM) 48 (41.38%), followed by polymyositis (PM) 36 (31.03%) and juvenile myositis (JDM) 18(15.52%). However, inclusion body myositis and necrotising myopathy were relatively rare conditions. The prevalence rates for DM, PM and JDM were determined as 2.2, 2.2, and 1.14 per 100,000 population respectively. Cardiac complications were observed in 14.66% of cases. Among the individuals studied, a history of malignancy was present in around 1.72% of cases. ANA antibodies were present in 71.55% of the cases, anti-Jo 1 and anti-RNP/SM antibodies were detected in 8.62%, and Anti-Ro antibodies in 24.14%. The overall mortality rate was found to be 6.90% with a rate of 11.1% among JDM cases. The five-year survival rates for PM, DM and JDM were found to be 94.4%, 91.7% and 89.0% respectively. These rates decline over a 10-year period to 67%, 69% and 83.3% respectively. CONCLUSIONS: The study highlights the prevalence, mortality, and survival rates of IIM in Oman. Patients with JDM had a higher mortality rate. This underscores the significance of using novel healthcare strategies to improve clinical outcomes and meet special requirements for this group of patients.

Secure and privacy-preserving automated machine learning operations into end-to-end integrated IoT-edge-artificial intelligence-blockchain monitoring system for diabetes mellitus prediction.

Diabetes Mellitus, one of the leading causes of death worldwide, has no cure to date and can lead to severe health complications, such as retinopathy, limb amputation, cardiovascular diseases, and neuronal disease, if left untreated. Consequently, it becomes crucial to be able to monitor and predict the incidence of diabetes. Machine learning approaches have been proposed and evaluated in the literature for diabetes prediction. This paper proposes an IoT-edge-Artificial Intelligence (AI)-blockchain system for diabetes prediction based on risk factors. The proposed system is underpinned by blockchain to obtain a cohesive view of the risk factors data from patients across different hospitals and ensure security and privacy of the user's data. We provide a comparative analysis of different medical sensors, devices, and methods to measure and collect the risk factors values in the system. Numerical experiments and comparative analysis were carried out within our proposed system, using the most accurate random forest (RF) model, and the two most used state-of-the-art machine learning approaches, Logistic Regression (LR) and Support Vector Machine (SVM), using three real-life diabetes datasets. The results show that the proposed system predicts diabetes using RF with 4.57% more accuracy on average in comparison with the other models LR and SVM, with 2.87 times more execution time. Data balancing without feature selection does not show significant improvement. When using feature selection, the performance is improved by 1.14% for PIMA Indian and 0.02% for Sylhet datasets, while it is reduced by 0.89% for MIMIC III.

Coexistence of sickle cell disease and systemic lupus erythematosus is associated with quantitative and qualitative impairments in circulating regulatory B cells.

The incidence of connective tissue diseases such as systemic lupus erythematous (SLE), in adult patients with sickle cell disease (SCD), appears to be increasing. The exact causes underlying this increased risk are still unknown, but a link with B regulatory (Breg) cells is possible as these cells suppress inflammatory responses, and maintain tolerance. Quantitative and qualitative analyses of circulating Breg cells were performed in a cohort of SCD patients with SLE, and their levels were correlated with key soluble mediators promoting autoreactive B cells. We demonstrated that levels of Breg cells were significantly decreased in SCD patients with SLE compared to patients with SCD only or healthy controls. Functional analysis of Breg cells from SCD patients with SLE revealed impairments in IL-10 production that correlated with lower levels of STAT3 phosphorylation, without abnormal expression of IL-10 receptor on Breg cells. On the other hand, BAFF levels were substantially elevated in SCD patients with SLE, but not significantly associated with Breg cell levels. Collectively, these results indicated numerical and functional deficits of Breg cells in SCD patients with SLE and their capacity to maintain tolerance and control inflammation is imbalanced, which leads to the development of autoimmune responses.

Screening, diagnosis and management of diabetic sensorimotor polyneuropathy in clinical practice: International expert consensus recommendations.

Diabetic sensorimotor polyneuropathy (DSPN) affects around one third of people with diabetes and accounts for considerable morbidity, increased risk of mortality, reduced quality of life, and increased health care costs resulting particularly from neuropathic pain and foot ulcers. Painful DSPN is encountered in 13-26% of diabetes patients, while up to 50% of patients with DSPN may be asymptomatic. Unfortunately, DSPN still remains inadequately diagnosed and treated. Herein we provide international expert consensus recommendations and algorithms for screening, diagnosis, and treatment of DSPN in clinical practice derived from a Delphi process. Typical neuropathic symptoms include pain, paresthesias, and numbness particularly in the feet and calves. Clinical diagnosis of DSPN is based on neuropathic symptoms and signs (deficits). Management of DSPN includes three cornerstones: (1) lifestyle modification, optimal diabetes treatment aimed at near-normoglycemia, and multifactorial cardiovascular risk intervention, (2) pathogenetically oriented pharmacotherapy (e.g. α-lipoic acid and benfotiamine), and (3) symptomatic treatment of neuropathic pain including analgesic pharmacotherapy (antidepressants, anticonvulsants, opioids, capsaicin 8% patch and combinations, if required) and non-pharmacological options. Considering the individual risk profile, pain management should not only aim at pain relief, but also allow for improvement in quality of sleep, functionality, and general quality of life.

A multicenter longitudinal study of the prevalence and mortality rate of systemic lupus erythematosus patients in Oman: Oman Lupus Study.

AIM: This study is a longitudinal multicenter study which aims to find the prevalence, the demographic data, survival and mortality rates of patients with systemic lupus erythematosus (SLE) in Oman. METHOD: All Omani patients, pediatrics and adults diagnosed with SLE, who fulfill either the 1997 American College of Rheumatology or Systemic Lupus International Collaborating Clinics classifications criteria for SLE were included from January 2006 till February 2020. RESULTS: In total 1160 patients were included in this cohort. Data analysis showed that patient's ages ranged from 2-82 years with female predominance and female-to-male ratio of 7:1 (87.7% female,12.3% male). The mean prevalence of SLE among different age groups was 38.8 (range 5-63 per 100 000 inhabitants). The mortality rate was found to be 5%. Male patients had significantly higher mortality rate than females (7.6% vs 5.4%, P value = .04). Sepsis was the commonest cause of mortality (34%). The coexistence of systemic sclerosis correlates significantly with death (P = .002). Survival analysis in our data showed 5, 10, 20, 40-year survival rates of 100%, 100%, 99% and 90% respectively for antinuclear antibody (ANA) positive patients and lower survival rate for ANA negative patients with 5,10, 20, 40-year survival rates of 100, 99%, 99% and 75%, respectively. CONCLUSION: This study showed that the mean prevalence of SLE in Oman to be 38.8 (range 5-63) per 100 000 inhabitants. The 40-year survival rate among patients with positive ANA was found to be 90%, while patients with negative ANA had worse survival outcomes.

Association of risk factors with type 2 diabetes: A systematic review.

Diabetes is the leading cause of severe health complications and one of the top 10 causes of death worldwide. To date, diabetes has no cure, and therefore, it is necessary to take precautionary measures to avoid its occurrence. The main aim of this systematic review is to identify the majority of the risk factors for the incidence/prevalence of type 2 diabetes mellitus on one hand, and to give a critical analysis of the cohort/cross-sectional studies which examine the impact of the association of risk factors on diabetes. Consequently, we provide insights on risk factors whose interactions are major players in developing diabetes. We conclude with recommendations to allied health professionals, individuals and government institutions to support better diagnosis and prognosis of the disease.

Association between duration of residence and prevalence of type 2 diabetes among male South Asian expatriate workers in the United Arab Emirates: a cross-sectional study.

Expatriates account for about 80% of the total population in the United Arab Emirates (UAE). This study aimed to evaluate the hypothesis that prevalence of type 2 diabetes in male South Asian expatriates increases with increased length of residence in the UAE. DESIGN, SETTINGS AND PARTICIPANTS: This cross-sectional study recruited a representative sample (n=1375) of male South Asian expatriates aged ≥18 years in Al Ain, UAE. Sociodemographic, anthropometric and lifestyle data were obtained using a pilot-tested adapted version of the WHO STEPS instrument. MAIN OUTCOME MEASURES: Duration of residence was used as a marker for acculturation. Type 2 diabetes was defined as a self-reported physician diagnosis of diabetes or a glycosylated haemoglobin blood level ≥6.5%. RESULTS: Mean (±SD) age of participants was 34.0±9.9 years. Overall, the prevalence of type 2 diabetes was 8.3% (95% CI 6.8% to 9.8%). Diabetes prevalence was positively associated with longer duration of residence in the UAE, 2.7%, <5 years; 8.2%, 5-10 years; and 18.8%, >10 years. After adjusting for age, nationality, and income and age, expatriates were more likely to develop diabetes if residing in the UAE for 5-10 years (OR=2.18; 95% CI 1.02 to 4.67) or >10 years (OR=3.23; 95% CI 1.52 to 6.85) compared with those residing for <5 years. CONCLUSIONS: After controlling for potential confounding factors, longer duration of residence was significantly associated with a higher prevalence of type 2 diabetes in male South Asian expatriate workers in the UAE.

Incidence and risk factors of type 2 diabetes mellitus in an overweight and obese population: a long-term retrospective cohort study from a Gulf state.

OBJECTIVES: A high body mass index (BMI) is associated with risk of type 2 diabetes mellitus (DM). The United Arab Emirates (UAE) is experiencing a marked increase in obesity. Nonetheless, no data are available regarding the incidence of type 2 DM in the high-risk adult UAE population. Therefore, this study aimed to evaluate the incidence rate and risk of developing type 2 DM among individuals with above-normal BMI in the UAE. DESIGN: A retrospective cohort study. SETTING: Outpatient clinics at a tertiary care centre in Al Ain, UAE. PARTICIPANTS: Three hundred and sixty-two overweight or obese adult UAE nationals who visited outpatient clinics between April 2008 and December 2008. PRIMARY OUTCOME MEASURE: Patients with type 2 DM were identified based on diagnosis established by a physician or through glycated haemoglobin (HbA1c) levels ≥6.5% during the follow-up period (until April 2018). RESULTS: The overall incidence rate of type 2 DM during the median follow-up time of 8.7 years was 16.3 (95% CI 12.1 to 21.4) cases per 1000 person-years. Incidence rates in men and women were 17.7 (95% CI 11.6 to 25.9) and 15.0 (95% CI 9.8 to 22.2) cases per 1000 person-years, respectively. Multivariable Cox proportional hazard analysis determined older age and obesity in women and pre-diabetes in men to be independent risk factors for developing type 2 DM. CONCLUSIONS: The incidence rate of type 2 DM in overweight and obese UAE nationals is high. In addition to screening, current strategies should strongly emphasise lifestyle modifications to decrease HbA1c and BMI levels in this high-risk population.

BRAF and KRAS mutations in papillary thyroid carcinoma in the United Arab Emirates.

BACKGROUND: Papillary thyroid carcinoma (PTC) is the most common malignant thyroid neoplasm comprising 80-90% of all thyroid malignancies. Molecular changes in thyroid follicular cells are likely associated with the development of PTC. Mutations in serine/threonine-protein kinase (BRAF) and Rat sarcoma viral oncogene homolog (RAS) are commonly seen in PTC. METHODS: In total, 90 cases of PTC are randomly selected from archive paraffin blocks and 10µm sections were cut and processed for DNA extraction. BRAF V600E mutation and 8 types of KRAS mutations were investigated using Real Time PCR. RESULTS: BRAF V600E mutation was identified in 46% of PTC while KRAS mutations were seen in 11% of PTC. There was significant correlation between BRAF V600E mutation and PTC larger than 5cm in diameter, positive surgical margin and lymph node metastasis. BRAF V600E mutation was significantly higher in patients with less than 55-year of age than those more than 55-year of age. BRAF V600E mutation was significantly higher in patients with family history of thyroid cancer than those without. There was no significant difference in BRAFV600E mutation between males and females, PTC classic and follicular variants, unifocal and multifocal PTC. There was a significant higher percentage of BRAF V600E mutation in classic PTC than papillary microcarcinoma variant. There was no significant age, gender, histologic type, tumor size, lymph node metastasis, tumor focality, and surgical margin status differences between KRAS mutated and non-mutated PTC. CONCLUSION: BRAF V600E and KRAS mutation are seen in a significant number of PTC in the UAE. BRAF mutation is significantly correlated with large tumor size, positive surgical margins and lymph node metastasis suggesting an association between BRAF V600E mutation and tumor growth and spread.

Metabolic syndrome among children aged 6 to 11 years, Al Ain, United Arab Emirates: Role of obesity.

OBJECTIVES: To evaluate the association of metabolic syndrome with the varying degrees of obesity among children aged 6 to 11 years in Al Ain, United Arab Emirates (UAE). METHODS: As an ancillary to the primary study examining prevalence of MetS in a random sample of 1186 adolescents from 114 schools in Al Ain, parents and siblings aged 6 to 11 years were invited to participate in this study. After informed consent from parents and assent from children, trained nurses administered questionnaires to assess socio-demographic and lifestyle variables and conducted anthropometric measurements. Fasting blood samples were drawn to measure plasma lipids and glucose. We used Centers for Diseases Control and Prevention (CDC)-defined categories of body mass index (BMI = kg/m2 ) for normal weight (<85th percentile), overweight (≥85th to 94th percentile), and obese (≥95th percentiles). MetS was defined according to National Cholesterol Education Program's (NCEP)/Adult Treatment Panel III (ATP III) criteria. RESULTS: Of the total 234 siblings aged 6 to 11 years, 8.9% (95% Confidence Interval [CI]: 5.6-13.4) had MetS. The prevalence of MetS increased with the severity of obesity, 4.5% in normal, 16.7% in overweight, and 30.0% in obese subjects. The age, sex, and ethnicity adjusted odds (1.55, 95% CI: 1.23-1.96) of MetS increased significantly with per unit increase in BMI. CONCLUSIONS: The prevalence of MetS in study subjects increased with an increase in BMI. School-based interventions targeting metabolic risks in this population are urgently needed.

Role of Functional Biomarkers to Identify Early Vitamin B12 Deficiency in Patients with Sleeve Gastrectomy: A Cross-Sectional Study.

Background and objectives: Although laparoscopic sleeve gastrectomy (LSG) is effective for obesity management, postoperative vitamin B12 (B12) deficiency is of major concern. In this cross-sectional study, we assessed the levels of B12 and its related functional biomarkers, namely, total homocysteine (tHcy), methylmalonic acid (MMA), folate, methylcitric acid (MCA), and hemoglobin (Hb), in one-year postoperative LSG patients and matched controls. Materials and Methods: Plasma B12, tHcy, MMA, folate, and MCA were measured in matched controls (n = 66) and patients (n = 71) using validated liquid chromatography-tandem mass spectrometry techniques and protocols in the United Arab Emirates (UAE). Results: The median B12 concentration in patients (177 pmol/L) was significantly lower (p < 0.001) than in the controls (334.7 pmol/L). The tHcy and MMA levels were significantly increased (p < 0.001 and p = 0.011, respectively) and folate levels were significantly decreased (p = 0.001) in the LSG patients compared to the controls. Interestingly, no significant difference in MCA levels were observed between the two groups. The levels of tHcy and MMA were concomitantly increased with the decreased folate levels in postoperative LSG patients when compared with the controls. The Hb levels were significantly lower in males and females in the patient group compared with those in the control group, respectively (p = 0.005 and p = 0.043). Conclusions: This is the first report of serum levels of B12 and its functional biomarkers in postoperative LSG patients among a local population from the UAE. Our findings revealed significant alterations of the B12 biomarkers, total B12, MMA, and tHcy in one-year postoperative LSG patients.

Epidemiology of Type 2 Diabetes - Global Burden of Disease and Forecasted Trends.

The rising burden of type 2 diabetes is a major concern in healthcare worldwide. This research aimed to analyze the global epidemiology of type 2 diabetes. We analyzed the incidence, prevalence, and burden of suffering of diabetes mellitus based on epidemiological data from the Global Burden of Disease (GBD) current dataset from the Institute of Health Metrics, Seattle. Global and regional trends from 1990 to 2017 of type 2 diabetes for all ages were compiled. Forecast estimates were obtained using the SPSS Time Series Modeler. In 2017, approximately 462 million individuals were affected by type 2 diabetes corresponding to 6.28% of the world's population (4.4% of those aged 15-49 years, 15% of those aged 50-69, and 22% of those aged 70+), or a prevalence rate of 6059 cases per 100,000. Over 1 million deaths per year can be attributed to diabetes alone, making it the ninth leading cause of mortality. The burden of diabetes mellitus is rising globally, and at a much faster rate in developed regions, such as Western Europe. The gender distribution is equal, and the incidence peaks at around 55 years of age. Global prevalence of type 2 diabetes is projected to increase to 7079 individuals per 100,000 by 2030, reflecting a continued rise across all regions of the world. There are concerning trends of rising prevalence in lower-income countries. Urgent public health and clinical preventive measures are warranted.

Prevalence of diabetes and cardio-metabolic risk factors in young men in the United Arab Emirates: A cross-sectional national survey.

INTRODUCTION: The aim of the study was to determine the prevalence of cardio-metabolic risk factors in men under 30 in the United Arab Emirates. METHODS: This cross-sectional observational study included 33 327 Emirati men aged 18-29 attending an obligatory standardized medical examination between May 2015 and February 2017. Body mass index, fasting blood glucose, total cholesterol, triglycerides and blood pressure were assessed. RESULTS: Overall, 7720 subjects (24.4%) were overweight and 8835 (28.0%) obese. The age-adjusted prevalence was 4.7% [95% CI: 4.4-5.0] for diabetes, 41.3% [40.6-41.9] for impaired fasting glucose, 5.5% [5.2-5.8] for hypercholesterolaemia (total cholesterol ≥ 240 mg/dL), 11.5% [11.1%-12.0%] for hypertriglyceridaemia (≥150 mg/dL) and 10.4% [10.0%-10.8%] for hypertension (diastolic or systolic blood pressure-or both-above upper limit of normal). These conditions were already present in the youngest age groups and rise progressively and rapidly with age. Of the 26 648 subjects with valid data for all cardio-metabolic risk factors, 16 563 subjects (62.2%) presented ≥ 1 factor, 6392 subjects presented ≥2 factors (24.0%) and 63 (0.2%) presented all five. Patients who were obese were more likely to present multiple cardio-metabolic risk factors and to have hypertension (P < 0.0001). All cardio-metabolic risk factors were highly correlated with each other. CONCLUSIONS: This national cohort study in the UAE revealed that obesity, diabetes, impaired fasting glucose, hypercholesterolaemia, triglyceridaemia and hypertension are already highly prevalent in young adulthood. Public health initiatives are required to address these and to anticipate the future burden of diabetes and major cardiovascular disease for which these men are at high risk.

Spectrum of systemic lupus erythematosus in Oman: from childhood to adulthood.

SLE is a disease that mainly affects women of childbearing age, however, a total of 15-20% of cases present in children. Although adult onset SLE (aSLE) and childhood onset SLE (cSLE) share the same diagnostic criteria, differences have been identified. The aim of this study is to compare the similarities and differences in between cSLE and aSLE in an Arab population from Oman. We evaluated 225 SLE patients, 139 adults and 86 children, who fulfilled the criteria for diagnosis. At disease onset, 99% of SLE cohort fulfilled the SLICC criteria; however the ACR 1997 criteria were fulfilled in 66% aSLE and 80% cSLE. The clinical features of SLE in cSLE showed higher frequency of renal (50 vs 19%; p < 0.001), musculoskeletal (67 vs 53%; p = 0.036) and pulmonary involvement (13 vs 2.9%, p = 0.005); while aSLE showed higher frequency of hematological (64 vs 49%; p = 0.25) and mucocutaneous (24 vs 10%; p = 0.13) involvement. The mean disease activity score at disease onset and during disease course was also higher in cSLE (13 vs 8.5; p < 0.0005) (16 vs 11.8; p < 0.0005), respectively. Differences in autoantibody profile were also noted in cSLE with higher positivity of anti-dsDNA and antiphospholipid antibody (94 vs 84%; p = 0.027) (53 vs 37%; p = 0.25), respectively. cSLE patients were more likely than aSLE to be treated with immunosuppressant such as cyclophosphamide (51 vs 22%; p < 0.001) and MMF (70 vs 54%; p = 0.019). Similarities and differences between aSLE and cSLE in a cohort from Oman of Arab ethnicity were identified. It appears that individual races and ethnicities may exhibit differences in disease susceptibility and manifestations.

Polypharmacological Properties and Therapeutic Potential of ß-Caryophyllene: A Dietary Phytocannabinoid of Pharmaceutical Promise.

BACKGROUND: ß-Caryophyllene (BCP) is a natural bicyclic sesquiterpene abundantly found in essential oils from various spices, fruits and medicinal as well as ornamental plants. It is approved by United States Food and Drug Administration and European agencies as food additive, taste enhancer and flavoring agent and termed as a phytocannabinoid. METHODS: All the available literature on BCP and its synonyms were collected through different literature databases. RESULTS: BCP was found to elicit a full agonist action on cannabinoid type 2 (CB2) receptors, a G-protein coupled receptor representing important therapeutic target in several diseases. Activation of CB2 receptors notably appeared devoid of psychotropic adverse effect of cannabinoids contrary to the CB1 receptors. In addition, it activates peroxisome proliferated activator receptors (PPARs) isoforms; PPAR-α &-γ and inhibits pathways triggered by the activation of toll like receptor complex; CD14/TLR4/MD2, reduce immuneinflammatory processes and exhibit synergy with µ-opioid receptor dependent pathways. Additionally, it found as potent antagonist of homomeric nicotinic acetylcholine receptors (α7-nAChRs) and devoid of effects mediated by serotonergic and GABAergic receptors. It also modulates numerous molecular targets by altering their gene expression, signaling pathways or through direct interaction. Various pharmacological activities such as cardioprotective, hepatoprotective, gastroprotective, neuroprotective, nephroprotective, antioxidant, anti-inflammatory, antimicrobial and immune-modulator have been reported in experimental studies. It has shown potent therapeutic promise in neuropathic pain, neurodegenerative and metabolic diseases. CONCLUSION: The present review provides a comprehensive insight of pharmacological and therapeutic potential of BCP, its molecular mechanism and signaling pathways in different pathological conditions. The review also examines the possibility of its further development as a novel candidate for various pathologies considering the polypharmacological and multifaceted therapeutic properties potential along with favorable oral bioavailability, lipophilicity and physicochemical properties.

Illiteracy and diabetic foot complications.

BACKGROUND: Diabetes is especially common in the United Arab Emirates. Its complications in patients residing in the region have yet to be fully explored. This study reports on foot problems in our diabetic patients, with emphasis on the impact of illiteracy on foot care and complications due to diabetes. METHODS: Adults were randomly recruited from the Diabetes Center at Tawam-John Hopkins affiliated hospital. A questionnaire addressing foot care and problems was completed for all patients. In addition, an examination was performed by a trained nurse, an endocrinologist, and a podiatrist. RESULTS: Four hundred twenty-two adults with type 2 (93%) or type 1 (7%) diabetes were enrolled; 67% were females. Patients' mean age was 52 ± 13 years and duration of diabetes ≥ 1 year. Illiterate patients were 51% and were less likely to practice foot care (p=0.002), recognize foot risk factors (p=0.004), use proper footwear (p=0.010), and being physically active (p<0.001). In addition, they were more likely to have diabetic complications, such as neuropathy (p=0.027), eye disease (p=0.032), hypertension (p<0.001), obesity (p=0.003), increased body fat percentage (p<0.001), reduced capillary refill time (p=0.002), reduced monofilament (p=0.003), and reduced vibration (p<0.001). Logistic regression analysis revealed literates [OR=2.4, CI=1.1-5.4, p=0.031], female gender [OR=2.7, CI=1.1-6.2, p=0.023], and history of foot ulcer [OR=6.0, CI=2.1-17.2, p=0.001] were predictors of practicing foot care. CONCLUSION: Illiteracy invoked significant challenges to diabetic attentiveness and imposed increased foot complications. Physicians should realize that illiterate patients are vulnerable and require effective strategies to improve their education about the disease and reduce their diabetic complications.

Gestational diabetes mellitus: Confusion among medical doctors caused by multiple international criteria.

AIM: The aim of this study was to appraise the current regional practices of screening, diagnosis and follow-up of gestational diabetes mellitus (GDM) because the approach to GDM is frequently inconsistent. MATERIAL AND METHODS: A 21-item questionnaire was distributed to physicians taking care of pregnant women in seven hospitals in the United Arab Emirates and one hospital in Oman. Besides assessing their attitudes towards testing for GDM, the questionnaire assessed familiarity with the Hyperglycemia and Pregnancy Outcome study and the International Association of Diabetes in Pregnancy Study Groups GDM guidelines. RESULTS: One hundred and forty-eight (93%) of the 159 questionnaires distributed to the medical doctors (106 [72%] obstetricians and 42 [28%] internists) were returned. For GDM screening, six hospitals used five different tests; two hospitals utilized one single test. For GDM diagnosis, six hospitals employed the 2-h, 75-g oral glucose tolerance test (OGTT) (four different criteria) while two hospitals used the 3-h, 100-g OGTT (single criteria). For post-delivery follow-up, the 2-h, 75-g OGTT and fasting plasma glucose were accepted by 103 (70%) and 38 (26%) of the 148 medical doctors, respectively. Ninety-eight (69%) of 143 responding physicians were aware of the Hyperglycemia and Pregnancy Outcome study, while 85 (61%) of 140 responders were familiar with the guidelines of the International Association of Diabetes in Pregnancy Study Groups; this knowledge was independent of specialty, seniority, academia, years in practice or country trained. CONCLUSIONS: Although this study is parochial, its implications are global; that is, further education of caregivers would make the discordant approach to GDM (within and between hospitals) more harmonious and improve the obstetric care of pregnant women.

Knowledge, attitude and practices of diabetic patients in the United Arab Emirates.

INTRODUCTION: Diabetes self-management education is a cornerstone of diabetes care. However, many diabetics in the United Arab Emirates (UAE) lack sufficient knowledge about their disease due to illiteracy. Thus, before considering any possible intervention it was imperative to assess present knowledge, attitudes, and practices of patients towards the management of diabetes. METHODS: A random sample of 575 DM patients was selected from diabetes outpatient's clinics of Tawam and Al-Ain hospitals in Al-Ain city (UAE) during 2006-2007, and their knowledge attitude and practice assessed using a questionnaire modified from the Michigan Diabetes Research Training Center instrument. RESULTS: Thirty-one percent of patients had poor knowledge of diabetes. Seventy-two had negative attitudes towards having the disease and 57% had HbA(1c) levels reflecting poor glycemic control. Only seventeen percent reported having adequate blood sugar control, while 10% admitted non-compliance with their medications. Knowledge, practice and attitude scores were all statistically significantly positively, but rather weakly, associated, but none of these scores was significantly correlated with HbA(1c). CONCLUSIONS: The study showed low levels of diabetes awareness but positive attitudes towards the importance of DM care and satisfactory diabetes practices in the UAE. Programs to increase patients' awareness about DM are essential for all diabetics in the UAE in order to improve their understanding, compliance and management and, thereby, their ability to cope with the disease.

Vitamin D deficiency among healthy adolescents in Al Ain, United Arab Emirates.

BACKGROUND: Although vitamin D deficiency has been studied in various adult populations, there are few data on the prevalence of this nutritional deficiency among healthy adolescents in the United Arab Emirates (UAE). This study was conducted to determine the prevalence of vitamin D deficiency and to examine its correlates in adolescents aged 15 to 18 years. METHODS: This was a cross-sectional study in urban schools. Healthy adolescents (N=315) from a sample of 8 schools were randomly selected from the 142 schools in Al Ain, Abu Dhabi Emirate. Outcomes measured included serum concentrations of 25-hydroxy vitamin D (25OHD), plasma lipids, blood sugar, blood pressure and anthropometric data, nutrition and lifestyle variables. RESULTS: Fourty-one participants (19.7%) were vitamin D deficient (serum 25OHD level ≤15 ng/mL [≤37.5 nmol/L]. Using a cutoff level of 25(OH) D of ≤20 ng/ml [≤50 nmol/l] 143 participants (45.4%) were vitamin D insufficient. Overall 65.1% of study participants were either vitamin D deficient or insufficient. The prevalence of vitamin D deficiency varied between boys (10%) and girls (28%). In a final multivariate model, serum 25(OH) D concentrations were inversely correlated with female gender, consumption of fast food per week, and body mass index and positively correlated with physical activity scores after adjustment for age. CONCLUSIONS: Vitamin D deficiency and insufficiency were highly prevalent in adolescents, and more common in girls.
