ABSTRACT Background Sodium‐glucose cotransporter‐2 (SGLT2) inhibitors improve glycemic and cardiovascular outcomes in type 2 diabetes mellitus (T2DM). However, their impact on quality of life (QoL) and patient‐reported outcomes (PROs) has not been systematically evaluated. We conducted a systematic review and meta‐analysis to assess the effect of SGLT2 inhibitors on QoL in patients with T2DM. Methods MEDLINE, Embase, Scopus, Cochrane and ClinicalTrials.gov were searched until 18 August 2025 for randomised controlled trials and post hoc analyses of SGLT2 inhibitors reporting validated QoL or PRO outcomes in adults with T2DM. A random‐effects model was used to estimate mean differences (MD) or odds ratios (OR) with 95% CIs. Subgroup analyses compared SGLT2 inhibitors with placebo and active comparators. Risk of bias was assessed using the Cochrane RoB‐2 tool. Results Ten studies including 5294 patients (SGLT2i: 2807; control: 2487) were included. SGLT2 inhibitors significantly improved: EQ‐5D Index score versus placebo (MD: 0.04, p = 0.008), DTR‐QoL against active comparators (MD: 6.99; p = 0.0006), DTSQ compared to active comparators (MD: 0.54; p = 0.006) and IWQoL (MD: 1.44; p = 0.005) versus placebo. Improvements were also observed in SHIELD WQ‐9 overall QoL (OR: 2.11; p = 0.005), emotional health (OR: 2.16; p = 0.006), self‐esteem (OR: 2.26; p = 0.006) and work performance (OR: 1.99; p = 0.04) compared with placebo. Conclusion Randomised evidence suggests SGLT2 inhibitors enhance EQ‐5D Index score, diabetes‐specific QoL and several PROs in T2DM, particularly in physical, emotional and treatment satisfaction domains, supporting their earlier use in this population.

Background: The role of dissecting the right paraesophageal lymph node (RPELN) in managing papillary thyroid carcinoma (PTC) remains a subject of debate. This meta-analysis examines both established and novel risk factors associated with RPELN metastasis. Methods: Relevant studies published up to December 2024 were retrieved using PubMed, Embase, Ovid, and Scopus search engines. Data were extracted and evaluated using the Newcastle-Ottawa scale. Statistical analysis was performed using Review Manager 5.4, with heterogeneity assessed through the Q-test and I²-test. Sensitivity analysis was conducted using the leave-one-out method, and the Egger regression test was used to generate a funnel plot for publication bias assessment. Results: Out of 2,444 articles screened, 26 studies involving 16,427 patients were included in the meta-analysis. The overall RPELN metastasis rate was 12.98% (2,133/16,427). The pooled analysis revealed significant associations between RPELN metastasis and the following factors: age under 55 years (P < 0.00001), male gender (P < 0.00001), tumor size >1 cm (P < 0.00001), multifocality (P < 0.00001), capsular invasion (P < 0.00001), vascular invasion (P < 0.00001), extra-thyroidal extension (P < 0.0001), central lymph node metastasis (P < 0.00001), lateral lymph node metastasis (P < 0.00001), Hashimoto’s thyroiditis (P = 0.002), micro-calcifications (P = 0.01), and altered echogenicity (P = 0.03). Conversely, no significant associations were observed for tumor location in the right lobe (P = 0.07), superior pole (P = 0.08), middle pole (P = 1.00), inferior pole (P = 0.28), or tumor margins (P = 0.93) (all P > 0.05). Conclusion: Factors such as age <55, male sex, tumor size >1 cm, multifocality, capsular invasion, vascular invasion, extra-thyroidal extension, central lymph node metastasis, lateral lymph node metastasis, and Hashimoto’s thyroiditis are significantly associated with RPELN metastasis. These should be carefully considered during RPELN dissection in PTC management. Presentation: Sunday, July 13, 2025

Abstract Rationale: Current guidelines recommend a short course of antibiotic therapy for ventilator-associated pneumonia (VAP) caused by non-fermenting gram-negative bacilli (NF-GNB). However, this approach has been associated with an increased risk of pneumonia recurrence. This meta-analysis aims to address inconsistencies in the literature and evaluate the efficacy of short-course versus long-course antibiotic therapy for VAP, particularly in cases due to NF- GNB. Methods: We systematically searched PubMed, Embase, the Cochrane Library, and ClinicalTrials.gov for randomized controlled trials (RCTs) comparing short versus long courses of antibiotic therapy in patients with VAP. The primary outcomes were the risk of all-cause mortality and pneumonia recurrence. Data were analyzed using RevMan 5.4, with risk ratio (RR) and mean difference (MD) as effect measures. Results: Our pooled analysis included seven RCTs. There was no significant difference in all- cause mortality between short- and long-course antibiotic regimens (RR 1.02; 95% CI: 0.88-1.18; Figure 1). However, a short course of antibiotics increased the incidence ofpneumonia recurrence, particularly in patients with VAP due to NF-GNB (RR 1.64; 95% CI: 1.18-2.29; Figure 1). There were no significant differences between the two regimens regarding the duration of mechanical ventilation (MD 0.01 days; 95% CI: -0.51 to 0.53 days), ICU (MD 0.10 days; 95% CI: -1.00 to 1.20 days) and hospital stay (MD -0.63 days; 95% CI: -3.18 to 1.91 days), or subsequent infection with or acquisition of resistant organisms (RR 0.89; 95% CI: 0.63-1.24). Conclusions: Our meta-analysis suggests that while a short course of antibiotics increases the risk of pneumonia recurrence in NF-GNB VAP, it does not impact mortality compared to a longer course. The clinical significance of the increased recurrence of pneumonia remains uncertain, as it did not result in worse clinical outcomes. A practical approach incorporating validated clinical criteria and biomarker thresholds to guide the duration of antibiotic therapy may be more effective for patients with NF-GNB VAP. Larger RCTs are needed to drawdefinitive conclusions in this population.
