Background: Hypertriglyceridemia, a common lipid disorder linked to increased risks of cardiovascular diseases and metabolic syndrome, remains a global health challenge. Traditional treatments, though widely used, often have limited efficacy and adverse effects. Olezarsen, a novel antisense oligonucleotide, targets apolipoprotein C-III and shows promise in significantly reducing triglyceride levels. Aim: To conduct a meta-analysis comparing Olezarsen with placebo in patients with hypertriglyceridemia. Methods: We performed an extensive literature search of PubMed, EMBASE, and Cochrane Library databases up to May 2024 to identify studies comparing Olezarsen and placebo in patients with hypertriglyceridemia, irrespective of comorbid cardiovascular disease. Effect estimates were pooled using a random-effects model and reported as risk ratios (RR) for dichotomous outcomes and standard mean differences (SMD) for continuous outcomes, with 95% confidence intervals (CIs) for each. Results: Three randomized controlled trials (RCTs) with a total of 334 participants were included. Olezarsen significantly reduced triglyceride levels at 6 months (SMD: -1.69; 95% CI -2.22 to -1.17; P < 0.00001; Figure ) and 12 months (SMD: -1.64; 95% CI -2.22 to -1.07; P < 0.00001; Figure ). VLDL levels also decreased at 6 months (SMD: -1.95; 95% CI -2.38 to -1.51; P < 0.00001) and 12 months (SMD: -0.83; 95% CI -1.13 to -0.53; P < 0.00001). Lipid profile improvements included reductions in total cholesterol, non-HDL cholesterol, and apoB levels, with increases in HDL cholesterol and apoA-1. Adverse events were comparable between Olezarsen and placebo, although serious adverse events were significantly higher in the Olezarsen group (RR: 2.55; 95% CI 1.17 to 5.58; p = 0.02). Conclusion: Olezarsen demonstrates significant efficacy in reducing triglyceride and VLDL levels while improving overall lipid profiles in hypertriglyceridemia patients. Despite higher rates of serious adverse events, its overall safety profile remains acceptable.

Background: Del Nido cardioplegia (DNC) has extensively been used for pediatric population undergoing cardiac surgery. However, its use in adult cardiac surgeries have been limited thus, its benefits are not yet fully known. This analysis was performed to evaluate the impact of DNC versus any other type of cardioplegia in adult patients who are undergoing cardiac surgery. Methods: We systematically searched PubMed, Cochrane Library, and Scopus from database inception till March 2023, and moderate to high-quality randomized controlled trials were included which compared DNC to other cardioplegia. The primary outcome was postoperative stroke and/or transient ischemic attack (TIA). Secondary outcomes included spontaneous rhythm return, postoperative myocardial infarction, all-cause mortality, postoperative atrial fibrillation, defibrillation after coronary reperfusion, postoperative intra-aortic balloon pump, postoperative kidney injury, postoperative low cardiac output syndrome, inotropic support, cardiopulmonary bypass time, cross-clamp time, blood transfusion, cardioplegia volume, hospital stay, intensive care unit stay, mechanical ventilation stay, postoperative left ventricular ejection fraction, and cardiac markers. Results: In this meta-analysis, 13 studies were included with a patient population of 2207. Stroke and/or TIA studies (risk ratio [RR]: 0.54, 95% CI [0.29, 1.00]) and all-cause mortality studies (RR: 1.30, 95% CI [0.66, 2.56]) were insignificant. From the secondary outcomes, spontaneous rhythm return (RR: 1.58, 95% CI [1.02, 2.45]), defibrillation after coronary reperfusion (RR: 0.49, 95% CI [0.30, 0.79]), inotropic support (RR: 0.70, 95% CI [0.57, 0.85]), composite risk of stroke and/or TIA and/or acute kidney injury and mortality (RR: 0.72, 95% CI [0.53, 0.99]), cross-clamp time (mean difference [MD]: −6.01, 95% CI [−11.14, −0.89]), blood transfusion (RR: 0.73, 95% CI [0.60, 0.90]), cardioplegia volume (MD: −537.17, 95% CI [−758.89, −315.45]), troponin T (MD: −1.71, 95% CI [−2.11, −1.32]), creatine phosphokinase-MB (MD: −2.96, 95% CI [−5.84, −0.07]) were significant. Whereas all other secondary outcomes were found to be insignificant. Conclusion: No significant difference was observed between patients undergoing Del Nido administration in comparison to other cardioplegia solutions for the primary outcome, stroke or/and TIA.

e20097 Background: Malignant Mesothelioma (MMe) is a neoplasm of mesothelium and has a very poor survival rate. Over half the patients of MMe express programmed death-ligand 1 (PD-L1) which binds to the PD-1 receptor on T-cells which in turn suppresses their ability to kill tumors. Pembrolizumab is a PD-1 inhibitor antibody and it has shown efficacy in combating MMe. Our analysis aims to summarize data related to objective response rates (ORR) and adverse effects of Pembrolizumab therapy in MMe patients. Methods: We conducted an online search through PubMed, Cochrane, and Clinicaltrials.gov databases from their inception till January 25, 2024, to identify studies that reported the use of Pembrolizumab in patients with MMe. Data were extracted and analyzed and proportions with their 95% confidence interval have been reported. Onlinemeta v1.0 was used for all analyses. Results: A total of six studies with 549 patients reported the use of Pembrolizumab in patients with MMe. ORR was observed in 36.2% (32.3% - 40.4%; p < 0.01) of patients receiving Pembrolizumab while 20.4% (17.2%- 24.0%; p < 0.01) of patients experienced adverse effects of the therapy. Median survival ranged from 9.5 to 17.3 months whereas progression-free survival ranged from 2.5 to 7.1 months in patients. Conclusions: Pembrolizumab has an ORR and safety profile comparable to other immunotherapies. Further studies are needed to extensively study the drug and its effects in detail in patients with MMe.

Introduction: Non-alcoholic fatty liver disease (NAFLD), spanning from non-alcoholic steatohepatitis (NASH) to liver fibrosis, poses a global health challenge amid rising obesity and metabolic syndrome rates. Effective pharmacological treatments for NASH and liver fibrosis are limited. Objective: This study systematically reviews and meta-analyzes the safety and efficacy of resmetirom, a selective thyroid hormone receptor-β agonist, in NASH and liver fibrosis treatment. By analyzing data from clinical trials, we aim to offer evidence-based recommendations for resmetirom’s use in managing these conditions and identify avenues for future research. Methods: Electronic databases (PubMed, Scopus, Science Direct, Google Scholar, ClinicalTrials.gov, and Cochrane CENTRAL) were systematically searched, supplemented by manual screening of relevant sources. Only English-language randomized controlled trials were included. Data extraction, risk of bias assessment, pooled analyses, and meta-regression were performed. Results: Three randomized controlled trials involving 2231 participants were analyzed. Resmetirom demonstrated significant reductions in hepatic fat fraction [standardized mean difference (SMD) −4.61, 95% CI −6.77 to −2.44, P < 0.0001], NASH resolution without worsening fibrosis [risk ratio (RR) 2.51, 95% CI 1.74–3.64, P = 0.00001), and liver fibrosis improvement (RR 2.31, 95% CI 1.20–4.44, P = 0.01). Secondary outcomes showed significant improvements in lipid profiles, liver enzymes, and NASH biomarkers with resmetirom treatment. Meta-regression revealed associations between covariates and primary outcomes. Conclusion: Resmetirom exhibits promising efficacy in reducing hepatic fat, improving NASH resolution, and ameliorating liver fibrosis with a favorable safety profile. Further research is warranted to validate findings and optimize therapeutic strategies for NASH and liver fibrosis management.

ABSTRACT The complications and symptoms of hypoparathyroidism remain incompletely defined. Measuring serum parathyroid hormone (PTH) and calcium levels early after total thyroidectomy may predict the development of chronic hypoparathyroidism. The study aimed (i) to identify symptoms and complications associated with chronic hypoparathyroidism and determine the prevalence of those symptoms and complications (Part I), and (ii) to examine the utility of early postoperative measurements of PTH and calcium in predicting chronic hypoparathyroidism (Part II). We searched Medline, Medline In-Process, EMBASE, and Cochrane CENTRAL to identify complications and symptoms associated with chronic hypoparathyroidism. We used two predefined criteria (at least three studies reported the complication and symptom and had statistically significantly greater pooled relative estimates). To estimate prevalence, we used the median and interquartile range (IQR) of the studies reporting complications and symptoms. For testing the predictive values of early postoperative measurements of PTH and calcium, we used a bivariate model to perform diagnostic test meta-analysis. In Part I, the 93 eligible studies enrolled a total of 18,973 patients and reported on 170 complications and symptoms. We identified nine most common complications or symptoms probably associated with chronic hypoparathyroidism. The complications or symptoms and the prevalence are as follows: nephrocalcinosis/nephrolithiasis (median prevalence among all studies 15%), renal insufficiency (12%), cataract (17%), seizures (11%), arrhythmia (7%), ischemic heart disease (7%), depression (9%), infection (11%), and all-cause mortality (6%). In Part II, 18 studies with 4325 patients proved eligible. For PTH measurement, regarding the posttest probability, PTH values above 10 pg/mL 12–24 hours postsurgery virtually exclude chronic hypoparathyroidism irrespective of pretest probability (100%). When PTH values are below 10 pg/mL, posttest probabilities range from 3% to 64%. Nine complications and symptoms are probably associated with chronic hypoparathyroidism. A PTH value above a threshold of 10 pg/mL 12–24 hours after total thyroidectomy is a strong predictor that the patients will not develop chronic hypoparathyroidism. Patients with PTH values below the threshold need careful monitoring as some will develop chronic hypoparathyroidism. © 2022 The Authors.
