Prostate-Specific Membrane Antigen in Prostate Cancer
Imaging plays a crucial role in the accurate staging of prostate cancer. Prostate-specific membrane antigen (PSMA) is overexpressed in prostate cancer cells, and targeting the PSMA protein for diagnostic purposes has become of great clinical value. Another valuable feature of PSMA is its opportunity to serve as a target for delivering radionuclide therapy to cancer cells. PSMA-ligands can be labeled with various radionuclides, such as alpha and beta-emitters.

Second-Generation Antiandrogen Therapy for Prostate Cancer
Prostate cancer therapy for locally advanced and metastatic diseases includes androgen deprivation therapy (ADT). Second-generation antiandrogens have a role in castration-resistant prostate cancer. Nevertheless, some patients do not respond to this therapy, and eventually all the patients became resistant. This is due to modifications to intracellular signaling pathways, genomic alteration, cytokines production, metabolic switches, constitutional receptor activation, overexpression of some proteins, and regulation of gene expression.

Diagnosis and Grading of Varicocelectomy
Varicocele is a frequently encountered urological disorder, which has a prevalence rate of 8 to 15% among healthy men. However, the incidence is higher in male patients with primary or secondary infertility, with up to 35 to 80% of varicocele cases occurring in this population. The clinical manifestations of varicocele typically include the presence of an asymptomatic mass that feels like a “bag of worms”, chronic scrotal pain, and infertility.

Chronic Kidney Disease Urine Metabolomics
One of the primary challenges regarding chronic kidney disease (CKD) diagnosis is the absence of reliable methods to detect early-stage kidney damage. A metabolomic approach is expected to broaden the current diagnostic modalities by enabling timely detection and making the prognosis more accurate. Analysis performed on urine has several advantages, such as the ease of collection using noninvasive methods and its lower protein and lipid content compared with other bodily fluids.

Recurrent Prostate Cancer after Radical Prostatectomy
The main prostate cancer (PCa) treatments include surgery or radiotherapy (with or without ADT). None of the suggested treatments eliminates the risk of lymph node metastases. Conventional imaging methods, including MRI and CT scanning, are not sensitive enough for the diagnosis of lymph node metastases; the novel imaging method, PSMA PET/CT scanning, has provided valuable information about the pelvic LN involvement in patients with recurrent PCa (RPCa) after radical prostatectomy.

Etiopathology of IC/BPS
Interstitial cystitis/bladder pain syndrome (IC/BPS) is a disabling disease, with a reported prevalence of 52—500/100,000 in the female and 8—41/100,000 in the male population. The etiopathology of IC/BPS is still unclear, impeding causal treatment. Biomarkers could help to better understand the etiopathology, to improve diagnosis, and to develop patient-tailored treatment.

Roles of Extracellular Vesicles in RCC Progression
Renal cell carcinoma (RCC) is the most common type of kidney cancer and is thought to originate from renal tubular epithelial cells. Extracellular vesicles (EVs) are nanosized lipid bilayer vesicles that are secreted into extracellular spaces by nearly all cell types, including cancer cells and non-cancerous cells. EVs are involved in multiple steps of RCC progression, such as local invasion, host immune modulation, drug resistance, and metastasis.

The Role of the Complement System in HUS
Hemolytic uremic syndrome (HUS) is an acute disease and the most common cause of childhood acute renal failure. HUS is characterized by a triad of symptoms: microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury. In most of the cases, HUS occurs as a result of infection caused by Shiga toxin-producing microbes: hemorrhagic Escherichia coli and Shigella dysenteriae type 1. They account for up to 90% of all cases of HUS. The remaining 10% of cases grouped under the general term atypical HUS represent a heterogeneous group of diseases with similar clinical signs. Emerging evidence suggests that in addition to E. coli and S. dysenteriae type 1, a variety of bacterial and viral infections can cause the development of HUS. In particular, infectious diseases act as the main cause of aHUS recurrence. The pathogenesis of most cases of atypical HUS is based on congenital or acquired defects of complement system.

Active Surveillance in Intermediate-Risk Prostate Cancer
Active surveillance (AS) is a monitoring strategy to avoid or defer curative treatment, minimizing the side effects of radiotherapy and prostatectomy without compromising survival. AS in intermediate-risk prostate cancer (PC) has increasingly become used. There is heterogeneity in intermediate-risk PC patients. Some of them have an aggressive clinical course and require active treatment, while others have indolent disease and may benefit from AS. However, intermediate-risk patients have an increased risk of metastasis, and the proper way to select the best candidates for AS is unknown. In addition, there are several differences between AS protocols in inclusion criteria, monitoring follow-up, and triggers for active treatment. A few large series and randomized trials are under investigation.

Sarcopenia Screening Among Patients Undergoing Peritoneal Dialysis
Sarcopenia, characterized by an aging-related progressive decline of skeletal muscle mass, strength, and physical performance, is frequently encountered in patients undergoing peritoneal dialysis (PD) and is associated with adverse clinical outcomes. However, the best screening tools facilitating the rapid detection of sarcopenia among patients undergoing PD remain unknown.

Educational Needs of Young Adult Renal Transplant Recipients
Renal transplantation is the gold-standard treatment for adolescents and young adults with end-stage renal disease. Despite enjoying excellent short-term outcomes, they suffer the worst rates of premature transplant function loss. Health behaviors: such as lack of adherence to immunosuppressive medications, are felt to be the major contributory factor. Understanding the educational needs of young renal transplant recipients allows healthcare practitioners to better support patients in managing their chronic disease.

Urinary Tract Infection and Microbiome
Urinary tract infection is one of the most common bacterial infections and can cause major burdens, not only to individuals but also to an entire society. Urinary tract infection is not only caused by invading uropathogenic bacteria but also by changes to the uromicrobiome milieu, and interactions with other microbial communities can also contribute.

A PRoliferation-Inducing Ligand in IgA Nephropathy Pathogenesis
A PRoliferation-Inducing Ligand (APRIL), the thirteenth member of the tumor necrosis factor superfamily, plays a key role in the regulation of activated B cells, the survival of long-lived plasma cells, and immunoglobulin (Ig) isotype class switching. Several lines of evidence have implicated APRIL in the pathogenesis of IgA nephropathy (IgAN).

Kidney Cancer and Chronic Kidney Disease
Kidney cancer and chronic kidney disease are two renal pathologies with very different clinical management strategies and therapeutical options. Nonetheless, the cellular and molecular mechanisms underlying both conditions are closely related. Renal physiology is adapted to operate with a limited oxygen supply, making the kidney remarkably equipped to respond to hypoxia. This tightly regulated response mechanism is at the heart of kidney cancer, leading to the onset of malignant cellular phenotypes. Although elusive, the role of hypoxia in chronic kidney diseases is emerging as related to fibrosis, a pivotal factor in decaying renal function.

Prevention of Renal Cell Carcinoma
With 400,000 diagnosed and 180,000 deaths in 2020, renal cell carcinoma (RCC) accounts for 2.4% of all cancer diagnoses worldwide. The highest disease burden developed countries, primarily in Europe and North America. Incidence is projected to increase in the future as more countries shift to Western lifestyles. Risk factors for RCC include fixed factors such as gender, age, and hereditary diseases, as well as intervening factors such as smoking, obesity, hypertension, diabetes, diet and alcohol, and occupational exposure. Intervening factors in primary prevention, understanding of congenital risk factors and the establishment of early diagnostic tools are important for RCC.

Care for Acute Kidney Injury Survivors
Acute kidney injury (AKI) is a serious problem, affecting multiple organs, and is associated with a high mortality. The severe consequences of AKI extend beyond hospital discharge to the outpatient setting. The post-hospital discharge of patients with AKI can have short- and/or long-term sequela. Patients with AKI are at a higher risk of progressively losing their kidney function up to end-stage kidney disease (ESKD).

Immune System Dysfunction and Inflammation in Hemodialysis Patients
Biocompatibility in hemodialysis (HD) has considerably improved, but remains an open issue to be solved, appearing essential to reduce systemic inflammation and enhance patients’ clinical outcomes. Clotting prevention, reduction in complement and leukocyte activation, and improvement of antioxidant effect represent the main goals. Platelet activation is one of the first steps occurring in HD patients, determining several events causing chronic sub-clinical inflammation and immune dysfunction involvement. Moreover, oxidative stress processes, resulting from a loss of balance between pro-oxidant factors and antioxidant mechanisms, have been described, highlighting the link with inflammation.

Dysuricemia on the Path toward Normouricemia
The disease concept of “dysuricemia” includes hyperuricemia and hypouricemia. Both influence diseases in humans. Uric acid plays dual roles in oxidative stress: it has both an anti-oxidative protective effect and a pro-oxidative and/or a harmful crystal-forming effect. Extensive research on the relationship between the serum urate (SU) level and several common disease risks show characteristic patterns that are broadly classifiable into three patterns: the “gout pattern,” “neurodegenerative disease (ND) pattern,” and “chronic kidney disease (CKD) and cardiovascular disease (CVD) pattern”. In short, “the lower, the better” is incorrect; the ideal is to maintain normouricemia, or an optimal SU level, to reduce the risks of the common diseases associated with dysuricemia.
