Collapsing glomerulopathy has been delineated as the most common morphological feature in COVID-19 individuals presenting with rapidly progressive renal failure and massive proteinuria. This condition, also known as COVID-19-associated nephropathy, has a poor prognosis. In COVID-19-related collapsing glomerulopathy, an immune dysfunction-mediated "second hit" to podocytes of African origin with APOL1 risk alleles was suggested. However, further research is still required to clarify this aspect of glomerulopathy. [ABSTRACT FROM AUTHOR]

The Oxford classification system has been found to have significant correlations with clinical and laboratory data in patients with IgA nephropathy. Studies have shown that higher grades of mesangial hypercellularity and endocapillary hypercellularity are associated with younger age, higher blood pressure, and higher levels of proteinuria. Segmental glomerulosclerosis has been found to be associated with more severe proteinuria, lower serum albumin levels, and higher levels of creatinine. Tubular atrophy/interstitial fibrosis has been associated with older age, higher serum creatinine levels, and lower estimated glomerular filtration rates. [ABSTRACT FROM AUTHOR]

Parathyroid cancer is a rare malignancy originating from the parathyroid glands, which regulate calcium levels in the body. This review article aims to provide a comprehensive overview of parathyroid cancer, including its epidemiology, etiology, clinical presentation, diagnostic methods, treatment options, and prognosis. The article also highlights recent advancements in research and potential future directions for improving the management of this challenging disease. [ABSTRACT FROM AUTHOR]

The article titled "Oncohypertension; treatment of high blood pressure in cancer patients" explores the connection between high blood pressure and cancer. It highlights that high blood pressure is a common comorbidity in cancer patients and that certain anti-cancer drugs can worsen or cause hypertension. The article emphasizes the need for further investigation into the relationship between hypertension and cardiovascular mortality, morbidity, and renal function. The concept of oncohypertension is introduced as a new entity among oncologists, nephrologists, and cardiologists. [Extracted from the article]
