Assessment of venous thromboembolism risk and adequacy of prophylaxis in selected acute care medical centres in Arabian Gulf States: results from the ENDORSE study
OBJECTIVES: To assess the prevalence of venous thromboembolism (VTE) risk in acutely ill surgical and medical patients in selected acute care centres in the Arabian Gulf States, and to determine the proportion of at-risk patients who received effective prophylaxis in accordance with 2004 American College of Chest Physicians (ACCP) guidelines.
MATERIALS AND METHODS: Eight hospitals from 3 countries (Kuwait, Kingdom of Saudi Arabia, and United Arab Emirates) contributed to the global ENDORSE (Epidemiological International Day for the Evaluation of Patients at Risk for Venous Thromboembolism in the Acute Hospital Care Setting) study. Medical records were reviewed for all the in-patients aged \u3e / = 40 years admitted to medical wards, and in patients aged \u3e / = 18 admitted to surgical wards. The VTE risk and recommended prophylaxis were assessed according to the 2004 ACCP guidelines.
RESULTS: Of 1,291 evaluable patients, 801 were considered at risk of VTE; 391 (48.8%) surgical patients and 410 (51.2%) medical patients. Of the 801 patients, 322 (40.2%) received ACCP-recommended VTE prophylaxis; 159 (40.7%) of surgical patients and 163 (39.8%) of medical patients.
CONCLUSIONS: The data showed that VTE prophylaxis was underutilized in high-risk hospitalized patients. We recommend that active measures should be implemented in acute care centres in these Arabian Gulf countries to ensure identification of patients at risk of VTE and institute the appropriate prophylaxis
Metabolic syndrome in Arab adults with low bone mineral density
Abstract: There are discrepancies in the reports on the association of metabolic syndrome (MetS) and its components with bone mineral density (BMD) and hence more population-based studies on this subject are needed. In this context, this observational study was aimed to investigate the association between T-scores of BMD at lumbar L1–L4 and full MetS and its individual components. A total of 1587 participants (84.7% females), >35 years and with risk factors associated with bone loss were recruited from February 2013 to August 2016. BMD was done at L1–L4 using dual-energy X-ray absorptiometry (DXA). T-Scores were calculated. Fasting blood samples and anthropometrics were done at recruitment. Fasting lipid profile and glucose were measured. Screening for full MetS and its components was done according to the National Cholesterol Education Programme Adult Treatment Panel III (NCEP ATP III) criteria. Logistic regression analysis revealed that the odds of having full MetS increased significantly from the lowest T-score tertile to the highest one in both sexes (OR, odd ratio (95% CI, confidence interval) of tertile 2 and 3 at 1.49 (0.8 to 2.8) and 2.46 (1.3 to 4.7), p = 0.02 in males and 1.35 (1.0 to 1.7) and 1.45 (1.1 to1.9), p < 0.01 in females). The odds remained significant
even after adjustments with age, body mass index (BMI), and other risk factors associated with bone loss. Among the components of MetS, only central obesity showed a significant positive association with T-score. The study suggests a significant positive association of T-score (spine) with full MetS irrespective of sex, and among the components of MetS this positive association was seen specifically with central obesity
The application of FRAX in Saudi Arabia
Summary
Assessment and treatment pathways based on age-specific intervention thresholds in Saudi Arabi can be used to identify patients at high risk of fracture and avoid unnecessary treatment in those at low fracture risk.
Purpose
Intervention thresholds for the treatment of osteoporosis have historically been based on the measurement of bone mineral density. The aim of the present study was to explore treatment paths and characteristics of women eligible for treatment in Saudi Arabia based on fracture probabilities derived from FRAX®.
Methods
The approach to the setting of intervention and assessment thresholds used the methodology adopted by the National Osteoporosis Guideline Group for FRAX-based guidelines in the UK but based on the epidemiology of fracture and death in Saudi Arabia. The methodology was applied to women age 40 years or more drawn from a tertiary referral population for skeletal assessment. Missing data for the calculation of FRAX was simulated using data from the referral and FRAX derivation cohorts.
Results
Intervention thresholds expressed as a 10-year probability of a major osteoporotic fracture ranged from 2.0% at the age of 50 years increasing to 7.6% at the age of 70 years. A total of 163 of 1365 women (11.9%) had a prior fragility fracture and would be eligible for treatment for this reason. An additional 5 women were eligible for treatment in that MOF probabilities lay above the upper assessment threshold. A BMD test would be recommended for 593 women (43.4%) so that FRAX could be recalculated with the inclusion of femoral neck BMD. Of these, 220 individuals would be eligible for treatment after a BMD test and 373 women categorised at low risk after a BMD test.
Conclusion
Probability-based assessment of fracture risk using age-specific intervention thresholds was developed for Saudi Arabia to help guide decisions about treatment

Longitudinal assessment of the quality of life and patterns of antidiabetic medication use in patients with type 2 diabetes, Saudi Arabia perspective, DISCOVER study
Objectives: Patients with type 2 diabetes nowadays have a wide range of new antidiabetic medications with better efficacy and safety. Physicians’ attitude toward selecting antidiabetic medications to reach targeted glycemic control and better quality-of-life (QOL) has not been studied prospectively. The global DISCOVER study aims to comprehensively provide a real-world assessment of the treatment pattern changes for patients with type 2 diabetes, in addition to QOL assessment. The Kingdom of Saudi Arabia was one of the countries participating in the DISCOVER study program. Methods: This study is a part of the prospective, longitudinal multinational DISCOVER study conducted in 38 countries including Saudi Arabia, a country facing an epidemic of type 2 diabetes, recruited 519 adult patients with type 2 diabetes with a mean age of 52.4 ± 11 years, where, they were followed up for three years period, where 477 patients completed the follow-up period. The clinical, biochemical, and patient lifestyle data were assessed periodically during the study period. DISCOVER study is registered with ClinicalTrials.gov identifiers: NCT02322762. Results: The most frequently used antidiabetic medications (ADMs) initially and during the follow-up were biguanides (metformin) and sulfonylureas (gliclazide, glibenclamide, glimepiride, glipizide, and glyclopyramide). Insulin (premix Insulin, basal insulin, and basal/bolus insulin) and dipeptidyl peptidase-4 (DPP-4) inhibitors (sitagliptin, vildagliptin, saxagliptin, and linagliptin) were the most frequent second and alternative of therapy. Other medications namely thiazolidinediones (TZds) (pioglitazone and rosiglitazone), incretins (exenatide and liraglutide), and Sodium-glucose co-transporter-2 (SGLT-2) inhibitors (canagliflozin) were used at a lesser rate. Drug availability, efficacy, and safety were the main determinants for choosing antidiabetic medications. The physical component score of the QOL had shown a significant decrease, while the mental component score has demonstrated an increase in QOL using SF36v2 Survey. Conclusions: There is an increasing trend of using of newly available ADMs, mainly DPP-4 inhibitors. The major limitation of ADMs use is related to efficacy, availability, and safety. This warrant taking all the measures to overcome these limitations through adopting a multidisciplinary team approach for close monitoring of the patients and any unfavorable side effects. Additionally, global insurance coverage for all patients with type 2 diabetes could be a solution for the drug availability factor.</p
Evaluation of 34 Cytokines and Vitamin D Status Reveal A Sexually-Dimorphic Active Immune Response to SARS-CoV-2
Background: Several observational studies have inconsistently demonstrated that vitamin D deficiency is a risk factor for coronavirus disease-19 (COVID-19) infection and severity. Discrepancies in results may partially be explained by the individuals’ immune profiles, which are modulated, in varying degrees, by vitamin D status and sex hormones. Methods: In this study we evaluated the differences and associations of serum levels of 25(OH)D with 34 cytokines in 220 adults (82 controls (41 males; 41 females) and 138 SARS-CoV-2 patients (79 males and 59 females)) with and without COVID-19. Results: Serum 25(OH)D levels were significantly lower in the SARS-CoV-2 group than in the controls. Serum IP-10, MCP-1, CRP, IFNγ, IL-10, IL-13, IL-17α, IL-23, and IL-6 were significantly higher in COVID-19 patients compared to controls. Serum levels of VEGF, IFNγ, IL-13, and IL-5 were significantly higher in male patients than in females. 25(OH)D was significantly correlated with EFG (R = 0.39, p < 0.05) and IL-15 (R = 0.39, p < 0.05) in male patients, while it was inversely correlated with CRP (R = −0.51, p < 0.05) in female patients. Conclusions: Altered levels of cytokines, chemokines, and vitamin D were observed in SARS-CoV-2 adult patients. These expressions were sexually dimorphic and thus highlight the sex-specific nature of the active immune response following SARS-CoV-2 infection
