Background: A low serum 25-hydroxyvitamin D (25(OH) D) concentration has been associated with a higher risk of type 2 diabetes mellitus (T2DM), especially in older people. Our aim in this randomized controlled trial was to evaluate the effect of vitamin D treatment on inflammatory markers in non-obese Lebanese patients with T2DM, living in Beirut, Lebanon. Methods: Non-Obese patients with T2DM (n = 88), deficient/insufficient in vitamin D, were randomly assigned into one of two groups—a treatment group receiving 30,000 IU cholecalciferol/week for a period of six months, and a placebo group. Serum concentrations of TNF-α, high-sensitivity C-reactive protein (hs-CRP), and Interleukin-6 (IL-6) were the primary outcomes. A homeostatic model of insulin resistance (HOMA-IR) was assessed, in addition to serum concentrations of fasting blood glucose (FBG), HbA1C, (25(OH) D), and PTH. Results: The vitamin D group showed higher blood levels of (25(OH) D) (p < 0.0001), and a significant reduction in hs-CRP and TNF-α concentrations (p < 0.0001) compared to placebo. The decrease perceived in IL-6 concentrations was not significant (p = 0.1). No significant changes were seen in FBG (p = 0.9) and HbA1c levels (p = 0.85). Conclusion: Six months of vitamin D supplementation led to a decrease in some inflammatory markers in patients with T2DM. Additional studies with a larger sample and a longer period are advised in this regard. This trial was registered at ClinicalTrial.gov; Identifier number: NCT 03782805.

A massive explosion have ripped Beirut on August 4, 2020, leaving behind more than 6000 casualties, 800 regular floor admissions, 130 intensive care unit admissions, and over 200 deaths. Buildings were destroyed, hospitals in Beirut were also destroyed, others became nonfunctional. A disaster code was initiated in all the hospitals. Victims were transported by the Lebanese Red Cross or by volunteers to the nearest hospital that was still functional. Hospitals were flooded in patients, the coordination between health care centers was missing. Each hospital was functioning to its maximum capacity. With the many challenges we had, a rapid response was initiated. An effective triage done outside the Emergency had the major role in saving lives. After the Beirut Explosion, an assessment of the disaster plan and a major evaluation of the hospitals’ coordination is needed.
Elevated homocysteine (Hc) levels have a well-established and clear causal relationship to epithelial damage leading to coronary artery disease. Furthermore, it is strongly associated with other metabolic syndrome variables, such as hypertension, which is correlated with type II diabetes mellitus (T2DM). Studies on T2DM in relation to Hc levels have shown both positive and negative associations. The aim of the present study is to examine the relationship between Hc levels and risk of T2DM in the Lebanese population. We sought to identify whether Hc associates positively or negatively with diabetes in a case–control study, where 2755 subjects enrolled from patients who had been catheterized for coronary artery diagnosis and treatment. We further sought to identify whether the gene variant MTHFR 667C>T is associated with T2DM, and how Hc and MTHFR 667C>T also impact other correlates of T2DM, including the widely used diuretics in this study population. We found that Hc levels were significantly reduced among subjects with diabetes compared to those without diabetes when adjusted for all potential confounders (OR 0.640; 95% CI [0.44–0.92]; p = 0.0200). The associations between Hc levels and other variates contradicted the result: hypertension associates positively with high Hc levels, and with T2DM. The MTHFR 667C>T only associated significantly with high Hc levels. These results suggest population-specific variations among a range of mechanisms that modulate the association of Hc and T2DM, providing a probe for future studies.

A low serum 25-hydroxyvitamin D [(25(OH) D)] concentration was shown to correlate with higher fasting blood glucose (FBG) and insulin levels. Since age affect insulin sensitivity and the metabolism, we aimed in this randomized controlled trial to investigate the effect of vitamin D supplementation on glucose homeostasis and index of insulin resistance in elderly subjects living in Beirut, Lebanon.
Waterpipe smoking is a rising global public health epidemic perceived by many users to be less harmful, though its toxicity overlaps or even exceeds that of cigarette smoking. Short-term cardiovascular changes due to waterpipe smoking are well established, but longer-term health impacts are still not fully elucidated. We aim to investigate the association of waterpipe smoking with myocardial infarction among patients undergoing cardiac catheterization. The study was performed on Lebanese patients referred for cardiac catheterization. Patient's blood was collected for metabolic measures and questionnaires were filled out to include socio-demographic, behavioral and pertinent medical characteristics of the study subjects. Myocardial infarction is significantly and independently associated with waterpipe smoking, with odds ratio (OR) of 1.329 (95% CI: [1.04-1.68]; p = .021), which is lower than that for cigarette smoking (OR = 1.87, 95% CI: [1.63-2.15]; p < .001). Only diabetes showed significant association with waterpipe smoking among MI enrollees (OR = 1.66, 95%CI: [1.04-2.63]; p = .032). The study provides yet another evidence for the adverse cardiovascular effects of waterpipe smoking on a clinical level. The harmful effects of waterpipe smoking should be underscored by health care professionals.

Objective: Chemical, biological, radiological, and nuclear (CBRN) incidents require meticulous preparedness, particularly in the Middle East and North Africa (MENA) region. This study evaluated CBRN response operational flowcharts, tabletop training scenarios methods, and a health sector preparedness assessment tool specific to the MENA region. Methods: An online Delphi survey engaging international disaster medicine experts was conducted. Content validity indices (CVIs) were used to validate the items. Consensus metrics, including interquartile ranges (IQRs) and Kendall’s W coefficient, were utilized to assess the panelists’ agreement levels. Advanced artificial intelligence computing methods, including sentiment analysis and machine-learning methods (t-distributed stochastic neighbor embedding [t-SNE] and k-means), were used to cluster the consensus data. Results: Forty experts participated in this study. The item-level CVIs for the CBRN response flowcharts, preparedness assessment tool, and tabletop scenarios were 0.96, 0.85, and 0.84, respectively, indicating strong content validity. Consensus analysis demonstrated an IQR of 0 for most items and a strong Kendall’s W coefficient, indicating a high level of agreement among the panelists. The t-SNE and k-means identified four clusters with greater European response engagement. Conclusions: This study validated essential CBRN preparedness and response tools using broad expert consensus, demonstrating their applicability across different geographic areas.
