Background: To evaluate the potential capability of preoperative urinary Prostate Cancer Antigen 3 (PCA3) in predicting adverse pathologic features in patients with any- risk prostate cancer undergoing open retro-pubic radical prostatectomy.

Methods: Sixty-one biopsy-proven, clinically localized prostate cancer patients who underwent open radical prostatectomy were included in a prospectively designed cohort to evaluate the association of PCA3 score with various Adverse Pathologic Features (APF). The Area Under the Curve (AUC) of the Receiver Operating Characteristics (ROC) curve was used to quantify the predictive accuracy of PCA3 and a cut-off point was calculated to determine the predictability potential of PCA3 in foretelling the study parameters.

Breast cancer (BC) is one of the common female cancers and it is characterized by considerable problems regarding its development and therapy. Long non-coding RNAs (lncRNAs) have been identified as significant modulators in BC development, especially, in tumorigenicity and chemoresistance. We therefore endeavor to present an up-to-date understanding of lncRNAs and their impact on BC progression and treatment, concerning molecular processes, treatment options, and use as a therapeutic opportunity.

Copy number variations in the SMN1 gene on chromosome 5 are the primary cause of Spinal Muscular Atrophy (SMA) disease, characterized by muscle weakness and degeneration due to impaired alpha motor neurons in the spinal cord. To obtain a comprehensive molecular understanding of the SMA, including carriers, silent carriers, and patients in the Iranian population, we analyzed data from 5224 individuals referred to Kariminejad - Najmabadi Pathology & Genetics Center, Tehran, Iran, between 2006 and 2023 using MLPA and quantitative RT-PCR methods. The carrier frequency of SMA was estimated to be 5.

Article Synopsis
  • This study examines heparin-induced thrombocytopenia (HIT-II), a serious complication in hospitalized patients receiving heparin, particularly after surgery or for deep vein thrombosis (DVT).
  • The research involved 754 patients and found a HIT-II incidence rate of 4.50%, with higher occurrences in older adults and females, along with increased thrombosis rates and elevated levels of various inflammatory markers.
  • The study concludes that platelet activation in HIT-II patients contributes to more thrombosis formation, longer hospital stays, and higher mortality rates compared to non-HIT patients.

Patients with diabetes commonly experience an aberrant production of free radicals and weakened antioxidative defenses, making them highly susceptible to oxidative stress development. This, in turn, can induce and promote diabetic complications. Therefore, utilizing antidiabetic agents with antioxidative properties can offer dual benefits by addressing hyperglycemia and reducing oxidative damage.

Therapeutic Apheresis in Pediatric Renal Transplant Recipients.

Exp Clin Transplant

October 2024

From the Urology and Nephrology Research Center, Shahidbeheshti of Medical Sciences, Tehran, Iran.

Clear guidelines for therapeutic apheresis in children after renal transplant do not exist. This article reviews the current experiences with therapeutic apheresis in pediatric transplant recipients. The ideal characteristics of removable substances should have all of the following criteria for an effective therapeutic apheresis: large molecular weight (>15 kDa), prolonged half-life, rapid elimination from the plasma, high intravascular distribution, and low turnover rate.

Background: The impact of CCR5-Δ32 on COVID-19 outcomes has been the focus of much research. This genetic variant may protect against SARS-CoV-2 infection, while others have produced conflicting results. Given the controversial results of previous research on different populations, we aimed to investigate the possible association between the CCR5-Δ32 variant and COVID-19 severity in an Iranian population.

The prevalence of kidney stone disease is increasing globally, with calcium oxalate stones being the most common type. Oxalyl-CoA decarboxylase (OXC), an enzyme produced by the gut bacterium Oxalobacter formigenes, plays a crucial role in oxalate metabolism. Deficiencies in OXC activity can lead to the accumulation of oxalate, contributing to kidney stone formation.

Article Synopsis
  • The study compares outcomes and complications of two types of laparoscopic surgery for large kidney stones: retroperitoneal laparoscopic pyelolithotomy (RLP) and transperitoneal laparoscopic pyelolithotomy (TLP), analyzing data from 273 patients.
  • Findings show that while stone size was larger in the TLP group, both types had similar operation times, hospital stays, and complication rates, except for a significantly higher rate of postoperative fever in the TLP group.
  • The study concludes that RLP may be a better alternative to TLP due to the lower incidence of postoperative fever, suggesting it could be a preferred method for treating large kidney stones.

Introduction: Hydatid disease (HD) rarely affects the genitourinary system, comprising only 2-4 % of all hydatid infections. While kidney involvement is more common, seminal vesicle HD is rarely reported.

Case Presentation: We describe a 39-year-old man with an incidentally found large pelvic hydatid cyst arising from the seminal vesicle.

Background: Stress urinary incontinence (SUI) is a widespread condition affecting more than 200 million people worldwide. Common treatments for this condition include retropubic colposuspension, and pelvic sling methods, which use autologous grafts or synthetic materials to support the bladder neck and urethral sphincter. Although these treatments have a cure rate of over 80%, adverse effects and recurrence may still occur.

Sodium glucose cotransporter 2 inhibitors (SGLT2is) are a newly developed class of anti-diabetics which exert potent hypoglycemic effects in the diabetic milieu. However, the evidence suggests that they also have extra-glycemic effects. The renin-angiotensin-aldosterone system (RAAS) is a hormonal system widely distributed in the body that is important for water and electrolyte homeostasis as well as renal and cardiovascular function.
