Background: RCTs studying the effect of sodium-glucose co-transporter 2 inhibitors (SGLT2i) on cardiovascular (CV) risk factors and outcomes have been underpowered to assess patients with overweight or obesity, thus presenting the need for a meta-analysis. Methods: Electronic databases were queried up till February 2022 for RCTs comparing SGLT2i with placebo in patients with overweight (BMI ≥25 kg/m2) or obesity (BMI ≥30 kg/m2) - irrespective of diabetes status - with a follow-up of ≥24 weeks. Meta-analyses were performed using the generic inverse variance technique and a random-effects model. Results are presented as weighted mean differences (WMD) for continuous outcomes, and hazard ratios (HR) for dichotomous outcomes. Outcomes studied were: (i) weight; (ii) systolic BP; (iii) diastolic BP; (iv) heart rate; (v) HDL-C; (vi) LDL-C; (vii) major adverse cardiac events (MACE), i.e., composite of CV death, non-fatal myocardial infarction (MI) and non-fatal stroke; (viii) composite of heart failure hospitalization and CV death (HFH/CV death); (ix) mortality; (x) MI; and (xi) stroke. Results: Seventeen RCTs (47,649 patients) were included. Compared with placebo, SGLT2i significantly reduced weight (WMD: -2.32 kg [-2.77, -1.88]), HbA1c (WMD: -0.79 % [-0.98, - 0.61]) and systolic BP (WMD: -2.15 mm Hg [-3.08, - 1.22]). SGLT2i did not have a significant effect on diastolic BP (WMD: -0.55 mmHg [-1.51, 0.41]), heart rate (WMD: 0.08 bpm. [-0.21, 0.37]), HDL-C (WMD: 1.62 mmol l -1 [-0.21, 3.45]) or LDL-C (WMD: 0.53 mmol l -1 [-0.88, 1.94]). Amongst CV outcomes, SGLT2i reduced the risk of MACE (HR: 0.90 [0.81, 0.99]), HFH/CV death (HR: 0.82 [0.75, 0.90]), and mortality (HR: 0.85 [0.77, 0.94]). No effect was noted on stroke (HR: 0.99 [0.85, 1.26]) or MI (HR: 0.89 [0.77, 1.02]). Conclusions: In patients with overweight or obesity, SGLT2i produce a modest but significant reduction in weight, systolic BP and HbA1c. SGLT2i may also reduce the risk of MACE, HFH/CV death, and mortality.

AbstractHealthcare workers (HCWs) have faced an increased amount of mental health struggles amidst the COVID‐19 pandemic. However, those in conflict‐based settings with fragile healthcare systems meet additional challenges. This study reviews violence, conflict and mental health among HCWs in five countries: Syria, Palestine, Yemen, Afghanistan and Lebanon. Our study reports that HCWs are targeted by violence, bombings, mistreatment and different forms of abuse, including verbal and physical. With the additional burdens of the pandemic including prolonged working hours, limited resources and insufficient humanitarian aid, the healthcare workers fall victim to increased levels of burnout and mental illnesses. The situation leads to dire consequences on their personal lives and professional development, compelling them to quit their job or country all together. Although healthcare workers remain resilient in these conflict‐based settings, immediate interventions are required to prevent violence against them and cater to their rapidly declining mental health.
