The (rs156697) Polymorphism Modifies Diabetic Nephropathy Risk.

Background and Objectives: In the development of type 2 diabetes mellitus (T2DM) and its complications, genetic and environmental factors play important roles. Diabetic nephropathy (DN), one of the major microangiopathic chronic diabetic complications, is associated with an increased risk of major cardiovascular events and all-cause mortality. The present study was designed to investigate the possible modifying effect of glutathione transferase polymorphisms (GSTM1, GSTT1, GSTP1 rs1138272/rs1695, GSTO1 rs4925 and GSTO2 rs156697) in the susceptibility to T2DM and diabetic nephropathy.

The Role of Nucleases Cleaving TLR3, TLR7/8 and TLR9 Ligands, Dicer RNase and miRNA/piRNA Proteins in Functional Adaptation to the Immune Escape and Xenophagy of Prostate Cancer Tissue.

The prototypic sensors for the induction of innate and adaptive immune responses are the Toll-like receptors (TLRs). Unusually high expression of TLRs in prostate carcinoma (PC), associated with less differentiated, more aggressive and more propagating forms of PC, changed the previous paradigm about the role of TLRs strictly in immune defense system. Our data reveal an entirely novel role of nucleic acids-sensing Toll-like receptors (NA-TLRs) in functional adaptation of malignant cells for supply and digestion of surrounding metabolic substrates from dead cells as specific mechanism of cancer cells survival, by corresponding ligands accelerated degradation and purine/pyrimidine salvage pathway.

Template-Independent Poly(A)-Tail Decay and RNASEL as Potential Cellular Biomarkers for Prostate Cancer Development.

The post-transcriptional messenger RNA (mRNA) decay and turnover rate of the template-independent poly(A) tail, localized at the 3'-untranslated region (3'UTR) of mRNA, have been documented among subtle mechanisms of uncontrolled cancer tissue growth. The activity of Poly(A) deadenylase and the expression pattern of RNASEL have been examined. A total of 138 prostate tissue specimens from 46 PC patients (cancer specimens, corresponding adjacent surgically healthy tissues, and in their normal counterparts, at least 2 cm from carcinoma) were used.

Development and Validation of a Multivariable Predictive Model for Mortality of COVID-19 Patients Demanding High Oxygen Flow at Admission to ICU: AIDA Score.

Introduction: Risk stratification is an important aspect of COVID-19 management, especially in patients admitted to ICU as it can provide more useful consumption of health resources, as well as prioritize critical care services in situations of overwhelming number of patients.

Materials And Methods: A multivariable predictive model for mortality was developed using data solely from a derivation cohort of 160 COVID-19 patients with moderate to severe ARDS admitted to ICU. The regression coefficients from the final multivariate model of the derivation study were used to assign points for the risk model, consisted of all significant variables from the multivariate analysis and age as a known risk factor for COVID-19 patient mortality.

Purine adducts as a presumable missing link for aristolochic acid nephropathy-related cellular energy crisis, potential anti-fibrotic prevention and treatment.

Aristolochic acid nephropathy is a progressive exposome-induced disease characterized by tubular atrophy and fibrosis culminating in end-stage renal disease and malignancies. The molecular mechanisms of the energy crisis as a putative cause of fibrosis have not yet been elucidated. In light of the fact that aristolochic acid forms DNA and RNA adducts by covalent binding of aristolochic acid metabolites to exocyclic amino groups of (deoxy)adenosine and (deoxy)guanosine, we hypothesize here that similar aristolochic acid adducts may exist with other purine-containing molecules.

The Association of Polymorphisms in and Genes Involved in Redox Homeostasis in the Development and Progression of Clear Cell Renal Cell Carcinoma.

Deleterious effects of SNPs found in genes encoding transcriptional factors, as well as antioxidant and detoxification enzymes, are disputable; however, their functional significance seems to modify the risk for clear cell renal cell carcinoma (ccRCC) development and progression. We investigated the effect of specific , , gene variants and haplotype on ccRCC risk and prognosis and evaluated the association between GSTP1 and regulatory (JNK1/2) and executor (caspase-3) apoptotic molecule expression in ccRCC tissue samples and the presence of GSTP1 : JNK1/2 protein : protein interactions. Genotyping was performed in 223 ccRCC patients and 336 matched controls by PCR-CTTP and qPCR.

Predictive Markers for Malignant Urothelial Transformation in Balkan Endemic Nephropathy: A Case-Control Study.

Balkan endemic nephropathy (BEN) is a chronic tubulointerstitial disease frequently accompanied by urothelial carcinoma (UC). In light of the increased UC incidence and the markers observed in BEN patients with developed UC, the aim of the current case-control study is to assess survivin, p53 protein, growth factors and receptors (VEGF, VEGFR1, IGF I, IGF-1R and IGFBP5), tumor marker (TF)/CD142, circulating soluble Fas receptor and neopterin, as potentially predictive markers for UC in patients with BEN (52 patients), compared to healthy, age-matched subjects (40). A threefold increase was registered in both circulating and urinary survivin level in BEN patients.

The assessment of knowledge and attitudes of men in Serbia about prostate cancer and possibilities for its early detection and treatment in 2011: a cross-sectional study.

Purpose: To assess the knowledge and attitudes of men in Serbia about prostate cancer (PCa) and possibilities for its early detection and treatment in 2011.

Methods: This cross-sectional study included 407 men of various ages and education levels selected randomly and divided in 2 groups according to age (up to 40 and over 40 years). The assessment of knowledge and attitudes was based on a survey made up of 12 multiple choice questions conducted with direct contact with respondents from October 15th to December 15th 2011 with their voluntary consent.

First reported case of fulminant TB with progression of infection from lungs to the genitourinary region.

Although tuberculosis (TB) is a curable disease, it continues to be one of the leading infections associated with death in the world. Extra-pulmonary TB (EPTB) occurs in approximately 10% of the total cases, presenting with lymph nodes, pleura, bone and genitourinary tract as the most common locations. Genitourinary tuberculosis, the second most common EPTB, is very difficult to diagnose unless there is a high index of suspicion.

Aim: We evaluated the influence of ratio between free-to-total prostate specific antigen (F/T PSA) and prostate specific antigen density (PSAD)-(F/T)/PSAD on reduction of unnecessary prostate biopsies in grey zone (prostate specific antigen (psa) value 4.0-10.0 ng/ml).

Transitional cell carcinoma in orthotopic ileal neobladder 12 years after radical cystectomy.

Introduction: Some cases of secondary adenocarcinoma developing in the replaced bowel segment of urinary diversions have been reported so far. Secondary adenocarcinoma develops 20 years after surgery in about 0.5% of those in whom an ileal segment is used.

Etiopathogenesis, diagnostics and history of surgical treatment of stress urinary incontinence.

Urinary incontinence represents involuntary urine leakage into the urethra. This pathological condition represents a major medical, social and hygienic problem. The paper presents risk factors for development of the disorder, as well as diagnostic methods applied in evaluation of the female patients.

New and experimental techniques in the treatment of benign prostatic diseases.

Background: Benign prostatic hyperplasia (BPH) and chronic prostatitis (CP) are disorders with high prevalence and have a great impact on overall morbidity in men. The patients that do not respond to medical therapy for lower urinary tract symptoms (LUTS) related to BPH are candidates for surgery. However, the number of men with BPH/LUTS seeking for non-surgical, or for less invasive treatment is growing.

Orthotopic urinary diversion after radical cystectomy in treatment of muscle invasive bladder cancer.

Surgical treatment of invasive carcinoma of the bladder in males includes total cystectomy removal of the prostate, seminal vesicles, and the distal parts of the urethers and the pelvic lymph node dissection as well. At this moment it is not possible to recommend a particular type of urinary diversion, but today in clinical practice commonly used derivative are ileal orthotopic neobladder as the continent one and ileal conduit as non-continent urinary diversion. Continent urinary diversion after radical cystectomy are the result of the application of technological innovation in surgery, but also knowledge, imagination and skill of well trained urologist.

Materials And Methods: Between February 2011 and January 2013, 73 patients with benign pros- tatic enlargement had undergone diode laser vaporization of prostate at our institution. The fol- lowing parameters were assessed at baseline, and after a follow-up period of 3 and 12 months: International Prostate Symptom Score, peak urinary flow rate, post-void residual urine volume, and quality of life score.

Genitourinary injuries associated with pelvic fractures.

Introduction: Pelvic fractures represent approximately 3% of all skeletal injuries. About 15% of patients with pelvic fractures have associated bladder or urethral injuries. The most common causes of pelvic fracture are motor vehicle accidents, motorcycle crashes, motor vehicles striking pedestrians, and falls.

Urinary prostate-specific antigen: predictor of benign prostatic hyperplasia progression?

Introduction: Urinary prostate-specific antigen (uPSA) can be used as additional parameter of benign prostatic hyperplasia (BPH) progression.

Materials And Methods: From January 2001 to December 2011, uPSA was determined in 265 patients with benign prostate. Based on total prostate volume (TPV), the patients with benign prostate were divided in two groups: TPV < 31 mL and TPV ≥ 31 mL.

The remnant of a congenital, blind- ended megaureter in a 23-year-old woman causing chronic pain and urinary infections.

Multicystic dysplastic kidney (MCDK) is a congenital anomaly as the result of abnormal interaction between the ureteric bud and metanephric mesenchyme. Unilateral MCDK can be associated with other anomalies of the genitourinary tract. Relatively rare associated anomaly is the presence of ipsilateral refluxing blind megaureter.

Repeated endoscopic treatments of multiple recurrent ureteral tumors following 15-year-long history of bladder tumors in the patient from endemic nephropathy region.

Ureteral urothelial tumors (UUT) are uncommon; their incidence is higher in areas affected by Balkan endemic nephropathy (BEN), with low-grade lesions prevalent. In these patients, the efficacy of conservative surgery is comparable to that of nephroureterectomy. Endoscopic treatment is indicated for single, small and low grade UUT, in older patients with significant comorbidity.
