Meta-Analysis
AIM
Bempedoic acid has shown noteworthy progress in the prevention and management of atherosclerotic cardiovascular disease (ASCVD) in recent years. However, there has been a lack of high-quality evidence regarding the risk reduction of clinical events with bempedoic acid. Therefore, the aim of this article is to conduct a comprehensive evaluation of the impact of bempedoic acid on the incidence of cardiovascular events.
METHODS
A systematic review and meta-analysis of randomized controlled trials pertaining to bempedoic acid was carried out. We conducted a systematic search across the Pubmed, Embase, and Cochrane Central Register of Controlled Trials databases to identify relevant studies published from inception to 23 April 2023. A total of four trials comparing the clinical benefit achieved with bempedoic acid versus placebo were included.
RESULTS
Our analysis comprised four trials that encompassed a total of 17,323 patients. In comparison to the placebo, bempedoic acid showed a significant reduction in the risk of major adverse cardiovascular events (MACE) [relative risk (RR), 0.86, 95% confidence interval (CI) 0.87-0.94]. Additionally, bempedoic acid substantially lowered the occurrence of fatal or nonfatal myocardial infarction (RR 0.76, 95% CI 0.66-0.89), hospitalization for unstable angina (RR 0.70, 95% CI 0.55-0.89), and coronary revascularization (RR 0.82, 95% CI 0.73-0.92). There was also a similar reduction in MACE in patients on the maximally tolerated statin therapy.
CONCLUSION
Bempedoic acid may reduce the risk of cardiovascular events regardless of whether the patient is taking stains or not.

Meta-Analysis Review
AIM
This systematic review and meta-analysis was conducted to synthesize the efficacy and safety of bempedoic acid in patients requiring lipid-lowering therapy.
METHODS
PubMed, Embase, and Scopus databases were searched for randomized controlled trials from inception till June 2023. The primary outcome was major adverse cardiovascular events (MACE), and secondary outcomes were all-cause mortality, serum lipid profile, and adverse events between bempedoic acid and comparators. ROB2 was used for risk of bias assessment. We pooled mean differences or relative risks (RR) along with 95% confidence intervals (random-effects model).
RESULTS
Five-hundred and thirty-one studies were screened and 17 (n = 21,131) were included for review. There was a significant reduction in the risk of MACE [RR, 0.88 (95% CI: 0.77 to 0.99), p = 0.03)] and all-cause mortality [RR, 0.90 (95% CI: 0.82 to 0.98), p = 0.02] following bempedoic acid treatment. Treatment with bempedoic acid led to a significant reduction in the mean serum total cholesterol [- 34.41 mg/dl (95% CI: - 42.43 to - 26.39), p < 0.001], low-density lipoprotein cholesterol (LDL-C) [- 33.91 mg/dl (95% CI: - 39.66 to - 28.17), p < 0.001], as well as high-density lipoprotein cholesterol (HDL-C) [- 2.40 mg/dl (95% CI: - 3.09 to - 1.71), p < 0.001] levels. However, there was a significant increase in the risk of hyperuricemia [RR, 2.05 (95% CI: 1.81 to 2.33), p < 0.001] following bempedoic acid treatment. The number needed to harm was large for all safety outcomes. The GRADE of evidence was moderate for all outcomes.
CONCLUSION
Bempedoic acid reduces the risk of MACE and all-cause mortality, lowers serum total cholesterol and LDL-C levels, and has a favorable safety profile. Trial registration ClinicalTrial.gov Identifier: CRD42023412837.

Review
BACKGROUND
Vesicoureteral reflux (VUR) affects 1-2% of children, predisposing them to pyelonephritis, renal scarring, and reflux nephropathy. Treatment aims to prevent febrile urinary tract infections (f-UTI) and long-term sequelae. While guidelines differ, the current consensus proposes individual risk-stratification and subsequent management strategies. Here, we systematically analyzed the current literature on Positional Instillation of Contrast Cystography (PIC) for individualized diagnostics in patients with recurrent f-UTIs.
OBJECTIVE
We present a comprehensive qualitative and quantitative synthesis. Outcomes were: 1. the ability of PIC to predict VUR in patients with negative voiding cystographies (VCUG), 2. the ability of PIC to predict occult contralateral VUR, 3. the correlation of occult VUR in PIC with dimercaptosuccinic acid (DMSA) scan findings, and 4. the incidence of postoperative f-UTI in children treated for occult VUR picked up on PIC.
STUDY DESIGN
We conducted a systematic review following the PRISMA guidelines, applying the following inclusion criteria: Children with occult VUR in PIC with negative VCUG.
RESULTS
We included nine studies with 496 symptomatic patients with a mean age of 6.8 years, published between 2003 and 2021. PIC detected VUR in 73% of patients. Out of them, 81% had low-grade and 19% high-grade VUR. Occult contralateral VUR was present in 41% children. The presence of renal scars on DMSA scan was 1.39 times more likely with occult VUR on PIC. 85% of patients did not experience recurrent f-UTIs after PIC and subsequent treatment.
DISCUSSION
PIC can detect occult VUR in patients with recurrent f-UTIs in whom VCUG is negative. However, we recommend a cautious approach in the use of PIC in clinical practice until further prospective studies confirm the validity of our outcome measures.
CONCLUSION
Identification, risk stratification, and prompt action are central in managing VUR. PIC can be helpful in identifying VUR in patients with recurrent f-UTI.

Actas Urologicas Espanolas 2024Lithiasis in renal graft recipients might be a dangerous condition with a potential risk of organ function impairment. (Review)
Review
INTRODUCTION
Lithiasis in renal graft recipients might be a dangerous condition with a potential risk of organ function impairment.
EVIDENCE ACQUISITION
A systematic literature search was conducted through February 2023. The primary objective was to assess the incidence of lithiasis in kidney transplant (KT) recipients. The secondary objective was to assess the timing of stone formation, localization and composition of stones, possible treatment options, and the incidence of graft loss.
EVIDENCE SYNTHESIS
A total of 41 non-randomized studies comprising 699 patients met our inclusion criteria. The age at lithiasis diagnosis ranged between 29-53 years. Incidence of urolithiasis ranged from 0.1-6.3%, usually diagnosed after 12 months from KT. Most of the stones were diagnosed in the calyces or in the pelvis. Calcium oxalate composition was the most frequent. Different treatment strategies were considered, namely active surveillance, ureteroscopy, percutaneous/combined approach, or open surgery. 15.73% of patients were submitted to extracorporeal shock wave lithotripsy (ESWL), while 26.75% underwent endoscopic lithotripsy or stone extraction. 18.03% of patients underwent percutaneous nephrolithotomy whilst 3.14% to a combined approach. Surgical lithotomy was performed in 5.01% of the cases. Global stone-free rate was around 80%.
CONCLUSIONS
Lithiasis in kidney transplant is a rare condition usually diagnosed after one year after surgery and mostly located in the calyces and renal pelvis, more frequently of calcium oxalate composition. Each of the active treatments is associated with good results in terms of stone-free rate, thus the surgical technique should be chosen according to the patient's characteristics and surgeon preferences.
