Meta-Analysis
BACKGROUND
Sodium-glucose co-transporter-2 (SGLT2) inhibitors have been studied in patients with heart failure, type 2 diabetes, chronic kidney disease, atherosclerotic cardiovascular disease, and acute myocardial infarction. Individual trials were powered to study composite outcomes in one disease state. We aimed to evaluate the treatment effect of SGLT2 inhibitors on specific clinical endpoints across multiple demographic and disease subgroups.
METHODS
In this systematic review and meta-analysis, we queried online databases (PubMed, Cochrane CENTRAL, and SCOPUS) up to Feb 10, 2024, for primary and secondary analyses of large trials (n>1000) of SGLT2 inhibitors in patients with heart failure, type 2 diabetes, chronic kidney disease, and atherosclerotic cardiovascular disease (including acute myocardial infarction). Outcomes studied included composite of first hospitalisation for heart failure or cardiovascular death, first hospitalisation for heart failure, cardiovascular death, total (first and recurrent) hospitalisation for heart failure, and all-cause mortality. Effect sizes were pooled using random-effects models. This study is registered with PROSPERO, CRD42024513836.
FINDINGS
We included 15 trials (N=100 952). Compared with placebo, SGLT2 inhibitors reduced the risk of first hospitalisation for heart failure by 29% in patients with heart failure (hazard ratio [HR] 0·71 [95% CI 0·67-0·77]), 28% in patients with type 2 diabetes (0·72 [0·67-0·77]), 32% in patients with chronic kidney disease (0·68 [0·61-0·77]), and 28% in patients with atherosclerotic cardiovascular disease (0·72 [0·66-0·79]). SGLT2 inhibitors reduced cardiovascular death by 14% in patients with heart failure (HR 0·86 [95% CI 0·79-0·93]), 15% in patients with type 2 diabetes (0·85 [0·79-0·91]), 11% in patients with chronic kidney disease (0·89 [0·82-0·96]), and 13% in patients with atherosclerotic cardiovascular disease (0·87 [0·78-0·97]). The benefit of SGLT2 inhibitors on both first hospitalisation for heart failure and cardiovascular death was consistent across the majority of the 51 subgroups studied. Notable exceptions included acute myocardial infarction (22% reduction in first hospitalisation for heart failure; no effect on cardiovascular death) and heart failure with preserved ejection fraction (26% reduction in first hospitalisation for heart failure; no effect on cardiovascular death).
INTERPRETATION
SGLT2 inhibitors reduced heart failure events and cardiovascular death in patients with heart failure, type 2 diabetes, chronic kidney disease, and atherosclerotic cardiovascular disease. These effects were consistent across a wide range of subgroups within these populations. This supports the eligibility of a large population with cardiorenal-metabolic diseases for treatment with SGLT2 inhibitors.

Comparative Study Meta-Analysis
OBJECTIVE
Balanced crystalloid and normal saline are routinely used in clinical anesthesia, but their safety and efficacy in non-cardiac surgeries are still unclear.
MATERIALS AND METHODS
PubMed, Embase, Web of Science, Cochrane Library, Wanfang, and CNKI, from January 1980 to March 2023, were searched. Studies comparing balanced crystalloid (BC) with normal saline (NS) during non-cardiac surgeries were included. The primary outcomes were clinical outcomes (acidosis, renal insufficiency, and mortality), and the secondary outcomes were pH value, Na+, Cl- and creatinine levels, and vasopressor requirement.
RESULTS
Forty-three RCTs were included in this meta-analysis. Low evidence revealed that the development of acidosis was lower in the BC group than in the NS group (OR: 0.05, 95% CI: 0.01-0.43, I2=80.8%, p=0.00), and no between-group difference exists in renal insufficiency and mortality. At the end of surgery and on postoperative day 1 (POD 1), the pH value was higher, and the levels of Na+ and Cl- were lower in the BC group. No between-group difference exists in creatinine level and vasopressor requirement.
CONCLUSIONS
Perioperative balanced crystalloids can maintain the stability of acid-base and electrolyte balance and reduce acidosis compared with saline, but they cannot reduce postoperative renal insufficiency and mortality.

Meta-Analysis Review
The reduced uterine perfusion pressure (RUPP) model is frequently used to study preeclampsia and fetal growth restriction. An improved understanding of influential factors might improve reproducibility and reduce animal use considering the variability in RUPP phenotype. We performed a systematic review and meta-analysis by searching Medline and Embase (until 28 March, 2023) for RUPP studies in murine. Primary outcomes included maternal blood pressure (BP) or proteinuria, fetal weight or crown-rump length, fetal reabsorptions, or antiangiogenic factors. We aimed to identify influential factors by meta-regression analysis. We included 155 studies. Our meta-analysis showed that the RUPP procedure results in significantly higher BP (MD = 24.1 mmHg; [22.6; 25.7]; = 148), proteinuria (SMD = 2.3; [0.9; 3.8]; = 28), fetal reabsorptions (MD = 50.4%; [45.5; 55.2]; = 42), circulating soluble FMS-like tyrosine kinase-1 (sFlt-1) (SMD = 2.6; [1.7; 3.4]; = 34), and lower fetal weight (MD = -0.4 g; [-0.47; -0.34]; = 113. The heterogeneity (variability between studies) in primary outcomes appeared ≥90%. Our meta-regression identified influential factors in the method and time point of BP measurement, randomization in fetal weight, and type of control group in sFlt-1. The RUPP is a robust model considering the evident differences in maternal and fetal outcomes. The high heterogeneity reflects the observed variability in phenotype. Because of underreporting, we observed reporting bias and a high risk of bias. We recommend standardizing study design by optimal time point and method chosen for readout measures to limit the variability. This contributes to improved reproducibility and thereby eventually improves the translational value of the RUPP model.

Review
BACKGROUND AND AIMS
High serum galectin-3 has been associated with adverse outcomes among dialysis patients, although its prognostic role remains unclear among individuals with earlier-stage chronic kidney disease. The present systematic review aims to evaluate the association of serum galectin-3 with survival, cardiovascular disease and kidney disease progression among non-dialysis chronic kidney disease patients.
METHODS
PubMed, Scopus, Web of Science, CENTRAL and Google Scholar were systematically searched till November 10, 2023. All observational studies assessing the prognostic role of serum galectin-3 in patients with non-dialysis chronic kidney disease were included.
RESULTS
Overall, 12 studies (10 cohort, 2 cross-sectional) were included, comprising 9,349 patients. The endpoint of survival was assessed in 5 studies, indicating a significant association between increasing serum galectin-3 levels and higher all-cause mortality risk (Hazard ratio per unit: 1.22, 95 % confidence intervals-CI: 1.05-1.41, ≥6 ng/mL: 2.66, 95 % CI: 1.68-4.23). Current evidence coming from 4 studies was inconclusive regarding the potential link of galectin-3 and kidney function decline, yielding conflicting results. No significant associations between serum galectin-3 and heart failure, cardiovascular events or death were consistently reported.
CONCLUSIONS
This systematic review supports the prognostic role of galectin-3 in chronic kidney disease, as its increased serum values may be associated with higher all-cause mortality risk. No clear role could be supported for serum galectin-3 regarding the prediction of cardiovascular disease or kidney disease progression.

Meta-Analysis Review
PURPOSE
It is unknown whether febuxostat can delay the progression of kidney dysfunction and reduce kidney endpoint events. The aim was to evaluate the renoprotective effect of febuxostat in patients with hyperuricemia or gout by performing a meta-analysis of randomized controlled trials (RCTs).
METHODS
MEDLINE, Web of science, EMBASE, ClinicalTrials.gov, and the Cochrane Central Register for Randomized Controlled Trials were searched. The main outcomes included kidney events (serum creatinine doubling or progression to end-stage kidney disease or dialysis). The secondary outcomes were the rate of change in the estimated glomerular filtration rate (eGFR) and changes in the urine protein or urine albumin to creatinine ratio from baseline to the end of follow-up. We used random-effects models to calculate the pooled risk estimates and 95% CIs.
RESULTS
A total of 16 RCTs were included in the meta-analysis. In comparison with the control group, the patients who received febuxostat showed a reduced risk of kidney events (RR = 0.56, 95% CI 0.37-0.84, = 0.006) and a slower decline in eGFR (WMD = 0.90 mL/min/1.73 m, 95% CI 0.31-1.48, = 0.003). The pooled results also revealed that febuxostat use reduced the urine albumin to creatinine ratio (SMD = -0.21, 95% CI -0.41 to -0.01, = 0.042).
CONCLUSION
Febuxostat use is associated with a reduced risk of kidney events and a slow decline in eGFR. In addition, the urine albumin to creatinine ratio decreased in febuxostat users. Accordingly, it is an effective drug for delaying the progression of kidney function deterioration in patients with gout. PROSPERO CRD42021272591.

Meta-Analysis Review
Acute kidney injury (AKI) following surgery with cardiopulmonary bypass (CPB-AKI) is common in pediatrics. Urinary liver-type fatty acid binding protein (uL-FABP) increases in some kidney diseases and may indicate CPB-AKI earlier than current methods. The aim of this systematic review with meta-analysis was to evaluate the potential role of uL-FABP in the early diagnosis and prediction of CPB-AKI. Databases Pubmed/MEDLINE, Scopus, and Web of Science were searched on 12 November 2023, using the MeSH terms "Children", "CPB", "L-FABP", and "Acute Kidney Injury". Included papers were revised. AUC values from similar studies were pooled by meta-analysis, performed using random- and fixed-effect models, with < 0.05. Of 508 studies assessed, nine were included, comprising 1658 children, of whom 561 (33.8%) developed CPB-AKI. Significantly higher uL-FABP levels in AKI versus non-AKI patients first manifested at baseline to 6 h post-CPB. At 6 h, uL-FABP correlated with CPB duration (r = 0.498, = 0.036), postoperative serum creatinine (r = 0.567, < 0.010), and length of hospital stay (r = 0.722, < 0.0001). Importantly, uL-FABP at baseline (AUC = 0.77, 95% CI: 0.64-0.89, n = 365), 2 h (AUC = 0.71, 95% CI: 0.52-0.90, n = 509), and 6 h (AUC = 0.76, 95% CI: 0.72-0.80, n = 509) diagnosed CPB-AKI earlier. Hence, higher uL-FABP levels associate with worse clinical parameters and may diagnose and predict CPB-AKI earlier.

Meta-Analysis
BACKGROUND
Chronic Kidney Disease (CKD) represents a major challenge for public health, with hypertension and diabetes being the main causes of its occurrence. Therefore, this study aims to determine the prevalence of hypertension (HTN) and diabetes mellitus (DM) in Peruvian patients with CKD.
METHODS
A systematic search for studies about CKD in Peru was carried out in PubMed, Scopus, Embase, Web of Science, ScienceDirect, Google Scholar, Virtual Health Library (VHL), and Scielo from 2011 to December 2023. The protocol of this research was registered in the international registry of systematic reviews, the Prospective International Registry of Systematic Reviews (PROSPERO), with registration number CRD42023425118. Study selection, quality assessment, and data extraction were performed independently by two authors. Study quality was assessed using the Joanna Briggs Institute Statistical Meta-Analysis Assessment and Review Instrument. A random-effects model with inverse variance weighting was used to estimate the combined prevalence of HTN and DM in Peruvian patients with CKD. To analyze data heterogeneity, the I statistical test was used. Statistical analysis was performed with R version 4.2.3.
RESULTS
A total of 1425 studies were retrieved, of which 23 were included in the final meta-analysis. A total of 43,321 patients with CKD were evaluated, of whom 52.22% were male and 47.78% were female. The combined prevalence of HTN in Peruvian patients with CKD was 38% (95% CI: 30-46%; 41,131 participants; 21 studies, I = 99%, p = 0), while the combined prevalence of DM in Peruvian patients with CKD was 33% (95% CI: 26-40%; 43,321 participants; 23 studies, I = 99%, p = 0).
CONCLUSION
Approximately one-third of Peruvian patients with CKD have HTN and DM. These findings highlight the importance of implementing prevention and control measures for these chronic noncommunicable diseases in the Peruvian population, such as promoting healthy lifestyles, encouraging early detection and proper management of hypertension and diabetes, and improving access to medical care and health services.

Review
INTRODUCTION
Persistent findings suggest women and patients identified as "female" are less likely to receive a kidney transplant. Furthermore, the limited research on transplantation among transgender and gender diverse people suggests this population is susceptible to many of the same psychosocial and systemic barriers.
OBJECTIVE
This review sought to 1) highlight terminology used to elucidate gender disparities, 2) identify barriers present along the steps to transplantation, and 3) summarize contributors to gender disparities across the steps to transplantation.
METHODS
A systematic review of gender and sex disparities in the steps towards kidney transplantation was conducted in accordance with PRISMA guidelines across four social science and public health databases from 2005 to 23.
RESULTS
The search yielded 1696 initial results, 33 of which met inclusion criteria. A majority of studies followed a retrospective cohort design (n = 22, 66.7%), inconsistently used gender and sex related terminology (n = 21, 63.6%), and reported significant findings for gender and sex disparities within the steps towards transplantation (n = 28, 84.8%). Gender disparities among the earlier steps were characterized by patient-provider communication and perception of medical suitability whereas disparities in the later steps were characterized by differential outcomes based on older age, an above average BMI, and Black racial identity. Findings for transgender patients pointed to issues computing eGFR and the need for culturally tailored care.
DISCUSSION
Providers should be encouraged to critically examine the diagnostic criteria used to determine transplant eligibility and adopt practices that can be culturally tailored to meet the needs of patients.

Meta-Analysis
This network meta-analysis of randomized controlled trials aimed to determine whether any individual dipeptidyl peptidase-4 (DPP-4) inhibitors increase the risk of acute kidney injury (AKI). The Medical Literature Analysis and Retrieval System Online via PubMed, the Cochrane Central Register of Controlled Trials and ClinicalTrials.gov were systematically searched to identify relevant studies. The primary outcome was AKI. A frequentist network meta-analysis was performed using a random-effects model to account for heterogeneity. Twenty-nine studies involving 56 117 participants were included. There were 918 cases of AKI (1.63%). The risk of bias was generally considered to be low. The only DPP-4 inhibitor that significantly increased the frequency of AKI when compared with placebo was sitagliptin (risk ratio 1.65, 95% confidence interval 1.22-2.23). However, because one study showed significant outliers in the funnel plot, in a highly heterogeneous population composed solely of patients undergoing surgery for coronary artery bypass graft, we conducted a post-hoc sensitivity analysis to exclude this study. The results showed no statistically significant difference in the risk of AKI between sitagliptin and placebo. Individual DPP-4 inhibitors do not appear to increase the risk of AKI. However, sitagliptin may be associated with AKI in patients with underlying severe cardiovascular disease.

Meta-Analysis
INTRODUCTION AND OBJECTIVES
The efficacy of fluconazole as a prophylactic strategy in patients with chronic kidney disease (CKD) on peritoneal dialysis (PD) with prior antibiotic exposure is controversial in the current literature. This study aimed to compare a strategy of fluconazole prophylaxis versus no-prophylaxis for patients in PD on antibiotics for previous episodes of peritonitis.
MATERIALS AND METHODS
We performed a systematic review and meta-analysis of observational studies and randomized controlled trials (RCTs) comparing fluconazole prophylaxis with no prophylaxis for PD-related peritonitis. The search was conducted on PubMed, EMBASE, and Cochrane Central in January 23, 2023. The outcome of interest was the occurrence of fungal peritonitis (FP).
RESULTS
We included six studies (1 RCT, 5 observational) with 4515 occurrences of peritonitis, of which 1098 (24.8%) received fluconazole prophylaxis in variable doses, whereas 3417 (75.6%) did not receive prophylaxis during peritonitis episodes. Overall, fluconazole prophylaxis was associated with a lower incidence of FP (OR 0.22; 95% CI 0.12-0.41; p<0.001; I=0%). Subgroup analysis of studies that administered daily doses of fluconazole also demonstrated a reduced incidence of FP in patients who received antifungal prophylaxis (OR 0.31; CI 0.14-0.69; p=0.004; I=0%).
CONCLUSIONS
In this meta-analysis of 4515 episodes of PD-related peritonitis, prophylaxis with fluconazole significantly reduced episodes of FP as compared with no antifungal prophylaxis.
