Adipose stem-cell-derived microvesicles ameliorate long-term bladder ischemia-induced bladder underactivity.

Background/purpose: The mechanism for long-term hypoxia/ischemia induced bladder underactivity is uncertain. It requires an effectively therapeutic treatment. Therefore, we determined the pathophysiologic mechanisms of long-term bilateral partial iliac arterial occlusion (BPAO)-induced bladder underactivity and explored the therapeutic potential of adipose-derived stem cells (ADSCs) and ADSC-derived microvesicles (MVs) on BPAO-induced bladder dysfunction.

1, 6-dilauroyl-D-fructofuranose ameliorates lipopolysaccharide-induced septic acute kidney injury via inhibiting caspase 1 mediated pyroptosis formation in rat.

Background: Sepsis is a systemic inflammatory state associated with acute kidney injury (AKI) and high mortality. However, sepsis-induced AKI cannot be effectively prevented or treated using current antimicrobial therapies and supportive measures. We explored the therapeutic effect of newly developed fructose esters on sepsis-induced AKI (S-AKI).

Prognostic Outcomes and Predictive Factors in Non-Metastatic Castration-Resistant Prostate Cancer Patients Not Treated with Second-Generation Antiandrogens.

Patients with non-metastatic castration-resistant prostate cancer (nmCRPC) and high-risk features frequently have progression to life-threatening metastasis without second-generation antiandrogens. This study investigated nmCRPC patients for the survival and prognostic factors from a cohort before the approved use of second-generation antiandrogens. From March 2016 to January 2021, 326 patients treated with second-generation antiandrogens for metastatic castration-resistant prostate cancer (mCRPC) or metastatic castration-sensitive prostate cancer were retrieved.

Predicting Clinically Significant Prostate Cancer Using Urine Metabolomics via Liquid Chromatography Mass Spectrometry.

Purpose: Biomarkers predicting clinically significant prostate cancer (sPC) before biopsy are currently lacking. This study aimed to develop a non-invasive urine test to predict sPC in at-risk men using urinary metabolomic profiles.

Materials And Methods: Urine samples from 934 at-risk subjects and 268 treatment-naïve PC patients were subjected to liquid chromatography/mass spectrophotometry (LC-MS)-based metabolomics profiling using both C18 and hydrophilic interaction liquid chromatography (HILIC) column analyses.

Association of prostate cancer with human papillomavirus infections: a case-control study.

Background: The highly oncogenic human papillomavirus (HPV) is associated with numerous cancer types. While the role of viruses in the development of certain cancers is well established, the association between HPV infections and prostate cancer remains a subject of ongoing debate. This study aimed to investigate a potential association of prostate cancer with HPV infections utilizing a case-control study.

Prediction of clinically significant prostate cancer through urine metabolomic signatures: A large-scale validated study.

Purpose: Currently, there are no accurate markers for predicting potentially lethal prostate cancer (PC) before biopsy. This study aimed to develop urine tests to predict clinically significant PC (sPC) in men at risk.

Methods: Urine samples from 928 men, namely, 660 PC patients and 268 benign subjects, were analyzed by gas chromatography/quadrupole time-of-flight mass spectrophotometry (GC/Q-TOF MS) metabolomic profiling to construct four predictive models.

Lung abscess with chronic cough secondary to xanthogranulomatous pyelonephritis: A rare case report.

Rationale: Xanthogranulomatous pyelonephritis (XGPN) is a form of chronic pyelonephritis caused by chronic calculus obstruction and bacterial infection, leading to the destruction of the renal parenchyma and calyces. Conservative treatment is usually not sufficient, and surgical intervention is still the main curative approach. XGPN with transdiaphragmatic extension and lung abscess formation is a rare condition.

Markers of Kidney Tubular Function Deteriorate While Those of Kidney Tubule Health Improve in Primary Aldosteronism After Targeted Treatments.

Background Targeted treatment with mineralocorticoid receptor antagonists (MRAs) or adrenalectomy in patients with primary aldosteronism (PA) causes a decline in estimated glomerular filtration rate; however, the associated simultaneous changes in biomarkers of kidney tubule health still remain unclear. Methods and Results We matched 104 patients with newly diagnosed unilateral PA who underwent adrenalectomy with 104 patients with unilateral PA who were treated with MRAs, 104 patients with bilateral PA treated with MRAs, and 104 patients with essential hypertension who served as controls. Functional biomarkers were measured before the targeted treatment and 1 year after treatment, including serum markers of kidney function (cystatin C, creatinine), urinary markers of proximal renal tubular damage (L-FABP [liver-type fatty-acid binding protein], KIM-1 [kidney injury molecule-1]), serum markers of kidney tubular reserve and mineral metabolism (intact parathyroid hormone), and proteinuria.

Repeated vertebral compression fractures in young adult may imply functional adrenal tumor.

Background: Patients with adrenal Cushing's syndrome (ACS) typically present with central obesity, hirsutism, hypertension, or glucose intolerance, which can be easily identified by a clinical physician. However, recognizing those with subclinical CS or those with less common symptoms and signs is challenging to the subspecialist, which can lead to delayed diagnosis and treatment. We report a case who presented with repeated vertebral fractures in 6 months.

Negative air ions through the action of antioxidation, anti-inflammation, anti-apoptosis and angiogenesis ameliorate lipopolysaccharide induced acute lung injury and promote diabetic wound healing in rat.

Negative air ions (NAIs) being bioactive and negative charged molecules may confer antioxidant and anti-inflammatory activity. We assessed the effect of NAIs on two inflammatory diseases in animal models including lipopolysaccharide (LPS) induced acute lung injury (ALI) and wound healing in diabetic rats. We used intra-tracheal infusion of LPS to induce ALI and made a full-thickness cutaneous wound in streptozotocin-induced diabetic female Wistar rats.

Diffused bladder wall calcification in a survivor with severe coronavirus disease 2019: A case report.

Rationale: Bladder calcification is a rare presentation that was first interpreted to be related to a urea-splitting bacterial infection. Aside from infection, other hypotheses such as schistosomiasis, tuberculosis, cancer, and cytokine-induced inflammatory processes have also been reported. Severe coronavirus disease 2019 (COVID-19) is known for its provoking cytokine storm and uninhibited systematic inflammation, and calcification over the coronary artery or lung has been reported as a long-term complication.

Tumor-Derived C-C Motif Ligand 2 Induces the Recruitment and Polarization of Tumor-Associated Macrophages and Increases the Metastatic Potential of Bladder Cancer Cells in the Postirradiated Microenvironment.

Purpose: Radiation therapy (RT) is mainly used for bladder preservation in patients with muscle-invasive bladder cancer. The response of urothelial tumors to RT remains unsatisfactory. We investigated the interaction of RT and tumor-associated macrophages (TAMs) in the context of bladder cancer radioresistance.
