Biomarkers of Acute Kidney Injury
Acute kidney injury (AKI) remains a complex challenge with diverse underlying pathological mechanisms and etiologies. The clinical applications of AKI biomarkers are becoming extensive and serving as relevant tools in distinguishing acute tubular necrosis from other acute renal conditions. Also, these biomarkers can offer significant insights into the risk of progression to chronic kidney disease (CKD) and in the context of kidney transplantation.

Protein-Bound Uremic Toxin in Chronic Kidney Disease
Uremic toxins (UTs), particularly protein-bound uremic toxins (PBUTs), accumulate in chronic kidney disease (CKD) patients, causing significant health complications like uremic syndrome, cardiovascular disease, and immune dysfunction. Innovations such as online hemodiafiltration aim to enhance the removal process, while novel adsorptive therapies offer a means to address the high affinity of PBUTs to plasma proteins.

Mechanisms of Cognitive Impairment in Chronic Kidney Disease
A notable feature of dementia in chronic kidney disease (CKD) patients is the high frequency of vascular dementia, making its prevention through the management of classical risk factors such as hypertension, diabetes mellitus, dyslipidemia, smoking, etc., associated with atherosclerosis and arteriosclerosis. Other effective measures, including the use of renin–angiotensin system inhibitors, addressing anemia, exercise therapy, and lifestyle improvements, have been reported. The incidence and progression of cognitive impairment (CI) may also be influenced by the type of kidney replacement therapy, with reports suggesting that long-duration dialysis, low-temperature hemodialysis, peritoneal dialysis, and kidney transplantation can have a preferable effect on the preservation of cognitive function. In conclusion, patients with CKD are at a higher risk of developing CI, with brain atrophy being a contributing factor.

Possible Therapeutic Strategies for ADPKD Patients
Gender exerts a significant influence on the occurrence and progression of many renal diseases, including ADPKD. ADPKD, impacting roughly 12 million individuals globally, affects both men and women equally. Mutations in PKD1 and PKD2 genes contribute to ADPKD, with gender playing a crucial role in disease manifestation and progression.

Etiology of Hyponatremia
A perturbation in the water balance rather than any change in salt content is the main cause of hyponatremia, the most frequent electrolyte abnormality, defined as a serum sodium concentration <135 mEq/L. Hyponatremia may be divided between mild (Na > 120 mEq/L) or severe (Na < 120 mEq/L) hyponatremia, and is most frequently observed in elderly ICU hospitalized patients. Based on tonicity, hyponatremia may be hypotonic (a decreased concentration of the solute), isotonic, and hypertonic (falsely low sodium). According to the volume of extracellular fluid (ECF), hyponatremia is further divided among hypovolemic, euvolemic, or hypervolemic hyponatremia. Finally, hyponatremia may develop rapidly as acute (<48 h), usually with severe symptoms, or slowly as chronic hyponatremia, usually being asymptomatic or with mild symptoms. Acute severe hyponatremia presents with severe CNS problems, increased hospitalization rates, and mortality. The treatment with 3% sodium chloride and a 100 mL IV bolus based on severity and persistence of symptoms needs careful monitoring. A non-severe hyponatremia may be treated with oral urea. In asymptomatic mild hyponatremia, an adequate solute intake with an initial fluid restriction of 500 mL/d adjusted according to the serum sodium levels is preferred. Vaptans could be considered in patients with high ADH activity regardless of whether they are euvolemic or hypervolemic. In general, the treatment of hyponatremia should be based on the underlying cause, the duration and degree of hyponatremia, the observed symptoms, and volume status of patient.

CRISPR-Cas System and Urological Malignancies
Urological cancers account for a significant portion of cancer diagnoses and mortality rates worldwide. The traditional treatment options of surgery and chemoradiation can have significant morbidity and become ineffective in refractory disease. The discovery of the Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) system has opened up new avenues for cancer research by targeting specific genes or mutations that play a role in cancer development and progression.

Nephrotic Glomerular Diseases
The nephrotic syndrome holds significant clinical importance and is characterized by a substantial protein loss in the urine. Damage to the glomerular basement membrane or podocytes frequently underlies renal protein loss. There is an increasing belief in the involvement of the complement system, a part of the innate immune system, in these conditions. Understanding the interactions between the complement system and glomerular structures continually evolves, challenging the traditional view of the blood–urine barrier as a passive filter. Clinical studies suggest that a precise inhibition of the complement system at various points may soon become feasible.

Middle Molecular Uremic Toxin and Blood Purification Therapy
The purpose of blood purification therapy is to remove uremic toxins, and middle molecules (MMs) are a specific target. An MM is defined as a solute that passes through the glomerulus with a molecular weight in the range of 0.5–58 kDa, and new classifications of “small-middle 0.5–15 kDa,” “medium-middle 15–25 kDa,” and “large-middle 25–58 kDa” were proposed.
