RESUMEN
Rheumatic Heart Disease (RHD) remains a leading cause of cardiovascular death (CVD) globally. Mitral Valve repair (MVP) and mitral valve replacement (MVR) are the two most commonly and successfully used techniques to treat the disease. MVP is associated with reduced post-operative complications compared to MVR; however, it carries the risk of valvular fibrosis and scarring. Given the lack of recommendations, inconsistent findings, and paucity of pathophysiological evidence at present, we aimed to conduct a meta-analysis and systematically review the available literature to determine the efficacy and safety of MVP compared to MVR in improving clinical outcomes among patients with RHD. A comprehensive literature search was conducted on MEDLINE (PubMed), Cochrane Central and Scopus from inception till September 2023. The primary objective was early mortality defined as any cause-related death occurring 30 days following surgery. Secondary outcomes included long-term survival defined as the time duration between hospital discharge and all-cause death. Infectious endocarditis, thromboembolic events (including stroke, brain infarction, peripheral embolism, valve thrombosis, and transient ischemic attack), and haemorrhagic events (any serious bleeding event that required hospitalisation, resulted in death, resulted in permanent injury, or required blood transfusion) were all considered as post- operative complications. Additionally aggregated Kaplan-Meier curves were reconstructed for long term survival, freedom from reoperation, and freedom from valve-related adverse events by merging the reconstructed individual patient data (IPD) from each individual study. A significant decrease in early mortality with MV repair strategy versus MV replacement [RR 0.63; P = 0.003) irrespective of mechanical or bioprosthetic valves was noted. The results reported significantly higher long-term survival in patients undergoing MVP versus MVR (HR 0.53; P = 0.0009). Reconstructed Kaplan-Meier curves showed that the long term survival rates at 4, 8, and 12 years were 88.6, 82.0, 74.6 %, in the MVR group and 91.7, 86.8, 81.0 %, in the MVP group, respectively. MVP showed statistically significant reduction in early mortality, adverse vascular events, and better long-term survival outcomes compared to the MVR strategy in this analysis.

Background and objectives: The incidence of morbidity and mortality in patients with type 2 diabetes mellitus is substantially correlated with cardiovascular disease and chronic kidney disease. The current guidelines recommend the use of renin-angiotensin system blockers, but recent studies probed into the effects of finerenone to mitigate the risk of cardiorenal events. This meta-analysis was performed to demonstrate the effects of finerenone on cardiorenal events, comprising cardiovascular mortality, heart failure, change in estimated glomerular filtration rate, and serum potassium levels. Methods: After screening with our eligibility criteria, 350 articles were identified with an initial literature search on multiple databases, including PubMed, Science Direct, and Cochrane Central. Seven randomized controlled trials with a total of 15 462 patients (n=8487 in the finerenone group; n=6975 in the control group) were included. Results: Patients receiving finerenone were at a reduced risk for cardiovascular mortality [HR: 0.84 (0.74, 0.95)], heart failure [OR: 0.79 (0.68, 0.92)], decrease in estimated glomerular filtration rate by 40% [OR: 0.82 (0.74, 0.91)] and by 57% [OR: 0.70 (0.59, 0.82)]; and a higher incidence of moderate hyperkalemia [OR: 2.25 (1.78, 2.84)]. Conclusion: Finerenone, owing to its better mineralocorticoid affinity, and a much lower risk of adverse effects, promises to be a much better alternative than other renin-angiotensin system blockers available for the treatment of chronic kidney disease patients with type 2 diabetes. Further trials should be conducted to provide more definitive evidence to assess the safety and efficacy of finerenone compared to spironolactone and eplerenone.
RESUMEN
BACKGROUND AND OBJECTIVES: Since publishing successful clinical trial results of mRNA coronavirus disease 2019 (COVID-19) vaccines in December 2020, multiple reports have arisen about cardiovascular complications following the mRNA vaccination. This study provides an in-depth account of various cardiovascular adverse events reported after the mRNA vaccines' first or second dose including pericarditis/myopericarditis, myocarditis, hypotension, hypertension, arrhythmia, cardiogenic shock, stroke, myocardial infarction/STEMI, intracranial hemorrhage, thrombosis (deep vein thrombosis, cerebral venous thrombosis, arterial or venous thrombotic events, portal vein thrombosis, coronary thrombosis, microvascular small bowel thrombosis), and pulmonary embolism. METHODS: A systematic review of original studies reporting confirmed cardiovascular manifestations post-mRNA COVID-19 vaccination was performed. Following the PRISMA guidelines, electronic databases (PubMed, PMC NCBI, and Cochrane Library) were searched until January 2022. Baseline characteristics of patients and disease outcomes were extracted from relevant studies. RESULTS: A total of 81 articles analyzed confirmed cardiovascular complications post-COVID-19 mRNA vaccines in 17,636 individuals and reported 284 deaths with any mRNA vaccine. Of 17,636 cardiovascular events with any mRNA vaccine, 17,192 were observed with the BNT162b2 (Pfizer-BioNTech) vaccine, 444 events with mRNA-1273 (Moderna). Thrombosis was frequently reported with any mRNA vaccine (n = 13,936), followed by stroke (n = 758), myocarditis (n = 511), myocardial infarction (n = 377), pulmonary embolism (n = 301), and arrhythmia (n = 254). Stratifying the results by vaccine type showed that thrombosis (80.8%) was common in the BNT162b2 cohort, while stroke (39.9%) was common with mRNA-1273 for any dose. The time between the vaccination dosage and the first symptom onset averaged 5.6 and 4.8 days with the mRNA-1273 vaccine and BNT162b2, respectively. The mRNA-1273 cohort reported 56 deaths compared to the 228 with BNT162b2, while the rest were discharged or transferred to the ICU. CONCLUSION: Available literature includes more studies with the BNT162b2 vaccine than mRNA-1273. Future studies must report mortality and adverse cardiovascular events by vaccine types.

BACKGROUND: This meta-analysis evaluates the safety and short-term oncological outcomes of laparoscopic vs. open surgery for gallbladder carcinoma(GBC). METHODS: Meta-analysis was performed on laparoscopic(LG) and open group(OG) studies. Data for survival outcomes were extracted from Kaplan-Meier curves and combined with Tierney's method to estimate hazard ratios(HRs) and 95% CIs. RESULTS: There was no significant difference in overall survival(HR: 1.01), disease-free survival(HR: 0.84), 30-day mortality(RR:1.10), overall recurrence(RR:0.93), intraoperative gallbladder violation(RR:1.17), operative time(WMD:8.32), number of patients receiving adjuvant chemotherapy(RR:1.06) and blood transfusion(RR: 0.81). A significant difference was seen in survival of T3 subgroup(HR:0.77) and number of lymph node dissections (LND)(WMD: 0.63) favoring OG, along with a decrease in postoperative complications(RR:0.65), greater incidence of R0 resections(RR:1.04), lower volume of intraoperative blood loss(WMD: 128.62), lower time in removing drainage tube(WMD: 1.35), shorter diet recovery time(WMD: 1.88), shorter hospital stay(WMD: 3.51), lower incidence of 90-day mortality(RR:0.49) favoring LG. A higher incidence of port-site recurrence(RR:1.99) was reported in LG. CONCLUSION: Laparoscopic surgery is non-inferior to the open approach in terms of oncological outcomes and has an improved rate of postoperative complications.

BACKGROUND: Non-Alcoholic Fatty Liver Disease (NAFLD) is one of the most common causes of chronic liver disease worldwide. There is no universally accepted effective treatment for NAFLD. Although various studies propose statins effective in lowering liver enzymes and in improving liver histology, their potency in the treatment and development of NAFLD remains unknown. PURPOSE: We conducted this meta-analysis to evaluate the efficacy of statins in the treatment and the development of NAFLD. METHODS: Electronic databases (MEDLINE and Cochrane CENTRAL) were searched from their inception until May 2021 for observational studies and randomized controlled trials (RCTs) that assessed the efficacy of statins for the treatment of NAFLD and its development. Studies were included irrespective of the dosage or duration, and their risk of bias was assessed. The outcomes of interest for our study were the effect of statins on liver histology (steatosis, fibrosis and necroinflammation, NAFLD activity score [NAS]) and liver enzymes (Alanine transaminase [ALT], Aspartate transaminase [AST], and Gamma-glutamyl transferase [GGT] levels). To pool continuous outcomes, a random-effects model was used to derive weighted mean difference (WMD) or standardized mean difference (SMD) and their corresponding 95% confidence intervals (CIs). Generic inverse variance was then used for different measurement units reported by the studies. For studies investigating the effects of statins on the development of NAFLD, generic inverse variance along with random effects model was used to derive odds ratio (ORs) and its corresponding 95% confidence interval (CI). RESULTS: A total of 14 studies including 1,247,503 participants were short-listed for our analysis. All the studies included in our analysis had a low to moderate risk of bias. The results of our analysis suggest that statins may significantly reduce the risk of developing NAFLD (OR:0.69, 95% CI [0.57,0.84]; p = 0.0002; I² =36%). Statin use significantly reduced ALT levels (WMD: -27.28, 95% CI [-43.06, -11.51]; p = 0.0007; I² =90%), AST levels (WMD: -10.99, 95% CI [-18.17, -3.81]; p = 0.003; I² =79%) and GGT levels (WMD: -23.40, 95% CI [-31.82, -14.98]; p < 0.00001; I² = 21%) in patients presenting with NAFLD at baseline. In liver histology outcomes, steatosis grade (SMD: -2.59, 95% CI [-4.61, -0.56]; p = 0.01; I² = 95%), NAS (WMD: -1.03, 95% CI [-1.33, -0.74]; p < 0.00001; I² = 33%), necro-inflammatory stage (WMD: -0.19, 95% CI [-0.26, -0.13]; p < 0.00001; I² = 0%) and significant fibrosis (OR:0.20, 95% CI [0.04, 0.95]; p = 0.04; I² = 97%) underwent notable reduction. However, fibrosis stage outcome (WMD: 0.07, 95% CI [-0.05, 0.20]; p = 0.27; I² = 0%) was non-significant. CONCLUSION: There was a significant decrease in transaminase and transferase levels. Marked improvement in liver histology of NAFLD patients was observed. Statin use also remarkably reduced the risk of developing NAFLD. Future large-scale trials can further aid in identifying the positive impact of statins in treatment for NAFLD and those at risk of developing it.
