BACKGROUND: In patients with chronic kidney disease (CKD), cardiovascular disease is found to be the primary cause of mortality, and after coronary artery bypass grafting (CABG), their prognosis deteriorates. METHODS: We conducted a meta-analysis comparing off-pump CABG versus on-pump CABG in CKD patients. We searched electronic databases, including PubMed, Cochrane, and Google Scholar, using relevant keywords. We included studies comparing off-pump CABG with on-pump CABG in patients with chronic kidney disease, which was defined as an estimated glomerular filtration rate (eGFR) < 60 ml/min per 1...

PURPOSE: The study aimed to evaluate the effect of fertitonex containing L-carnitine L-tartrate together with other micronutrients on different semen parameters in idiopathic male infertility as well as male reproductive hormones. METHODS: 100 randomized infertile patients were recruited from July 2023 to February 2024. They were randomized into two groups. Group (A) received fertitonex twice daily for the first 3 months. Group (B) received placebo twice daily for the first 3 months...

PURPOSE: This study aimed to explore the correlation between hemoglobin levels and albuminuria in US adults. METHODS: This cross-sectional investigation analyzed the National Health and Nutrition Examination Survey (NHANES) information from 2011 to 2020. Data on hemoglobin, albuminuria, and other variables were collected from all participants. The logistic-regression analyses and smoothed curves were used to substantiate the research objectives. RESULTS: The average age of the 8,868 participants was 49...

This retrospective analysis investigates the outcomes and complications of 682 kidney biopsies performed at ARNAS G. Brotzu from 2010 to 2021. Our findings indicate a minor complication rate of 9.1%, with severe complications being exceedingly rare at 0.3%. Age did not contribute to an increased risk, underscoring the procedure's safety across age groups. Clinical hypnosis was incorporated into the biopsy protocol in a subset of patients (n = 45) from April 2019 to December 2023. Over 90% of these patients reported no perception of the procedure, and 60% experienced no pain...

PURPOSE: To evaluate whether commonly used comorbidity indices [Charlson Comorbidity Index (CCI), Van Walraven Index (VWI), and modified frailty index (mFI)] predict postoperative readmissions and complications after urethroplasty. METHODS: Patients undergoing urethroplasty for urethral stricture from the State Inpatient Database and State Ambulatory Surgery and Services Database for Florida (2010-2015) and California (2010-2011) were identified. We calculated CCI, VWI, and mFI scores for each patient...

BACKGROUND: There are increasing reports of glomerular disease (GD) following COVID-19 infection and vaccination. Current evidence on the possible link between COVID-19 infection or vaccination and GD is conflicting. OBJECTIVE: The present study undertakes a scoping review of research to describe the relationship between COVID-19 infection and vaccination with GD and the common management strategies and overall outcomes of the disease to identify knowledge gaps and guide further research...

PURPOSE: Parathyroid hormone (PTH) is merit as a risk factor for mortality in patients with chronic kidney disease in prevalent hemodialysis patients in a U shape. Most studies, however, do not focus on incident patients and those who died within the first 90 days of therapy. We evaluated PTH as a risk factor for mortality in a large cohort population in Brazil. METHODS: This is an observational cohort study that included 4317 adult patients who initiated hemodialysis between July 1st, 2012 and June 30, 2017...

BACKGROUND: Ureteral DJ stents are commonly used devices in urology. However, stent placement may cause LUTS and affect the quality of life. We evaluated the direct relationship between ureteral stents and sexual function. METHODS: From October 2022 to December 2023, 82 male and 90 female sexually active patients who underwent ureteroscopy at Beijing Tiantan Hospital, Capital Medical University, were enrolled. The basic information, surgical data, and two questionnaire data including the International Index of Erectile Function-5 and the Female Sexual Function Index of patients before the operation (baseline, T0), on the day of the ureteral DJ tube extraction (T1), and 4 weeks after ureteral DJ tube extraction (T2) were collected to analyze the changes in the patients' sexual function...

INTRODUCTION: Trimethylamine (TMA), produced by gut microbiota, is the precursor of trimethylamine-N-oxide (TMAO), a uremic toxin that accumulates in patients with chronic kidney disease (CKD). Elevated TMAO plasma levels are associated with cardiovascular complications and CKD progression. OBJECTIVE: To evaluate the association between gut microbiota composition and TMAO plasma levels in CKD patients undergoing hemodialysis (HD). METHODS: This is a cross-sectional study with 25 patients evaluated (60% female, 53 (18) years, body mass index (BMI) 25...

PURPOSE: This study aims to develop and propose the key criteria and elements necessary to be included in digital platforms for achieving high-quality monitoring of patients with chronic kidney failure. METHODS: The research was conducted from 2021 to 2023 in Moscow, Russia. A total of 75 patients comprised the experimental group (digital monitoring), while an equal number constituted the control group (standard nursing care). RESULTS: Patients in the experimental group highly rated the convenience (4...

PURPOSE: After radical prostatectomy (RP), it is rarely acknowledged that several sexual dysfunctions can arise. These include issues in the orgasmic domain (e.g., decreased orgasm intensity, dysorgasmia), problems with ejaculation (e.g., absence of ejaculation), the development of penile deformities, and low sexual desire. This article aims to report the occurrence of orgasmic and ejaculatory dysfunction when actively investigated, documenting those rates and characterizing specific features of these conditions following RP...

PURPOSE: The use of topical corticosteroids (TCSs) has become an efficient, less-invasive treatment for phimosis. Whether any significant difference in efficacy exists between TCSs based on their potency is unclear. METHODS: Electronic databases were searched up to March 2024 for randomised controlled trials (RCTs) comparing the use of any type or concentration of TCSs with placebo or no treatment in boys with any degree of physician diagnosed phimosis. A random-effects network meta-analysis (NMA) using a consistency model within a frequentist approach was employed...

PURPOSE: Growth differentiation factor 15 (GDF-15) is a cytokine involved in regulating homeostasis, and its expression is up-regulated in response to injury, stress, and inflammation. This study explored the role of GDF-15 in diabetic nephropathy (DN), a severe complication of diabetes mellitus, and its potential as a biomarker for disease progression. METHODS: As a member of the transforming growth factor-β superfamily, GDF-15 exhibits its renal protective functions primarily through its anti-inflammatory effects and the up-regulation of other renal protective factors...

BACKGROUND: Advancements in treatment regimens have led to improved outcomes in renal Immunoglobulin light-chain amyloidosis. Nevertheless, a subset of patients may still experience renal adverse events despite achieving hematologic very good partial response or better. This discrepancy may be attributed to the deposition pattern of amyloid in renal tissue. To enhance prognostic assessment, a staging system that incorporates both pathological characteristics and clinical indicators should be developed...

PURPOSE: To quantify to what extent the 5-year overall survival (OS) of adrenocortical carcinoma (ACC) patients differs from age- and sex-matched population-based controls, especially when stage is considered. METHODS: We relied on the Surveillance, Epidemiology, and End Results database (2004-2020) to identify newly diagnosed (2004-2014) ACC patients. Subsequently, we compared OS between ACC patients relative to simulated age- and sex-matched controls (Monte Carlo simulation), according to Social Security Administration Life Tables (2004-2020)...
