Article Abstract

Diabetes associated with post-menopause is related to a worse condition of kidney disease. Taking into consideration that this disorder may be regulated by estrogenic mediators, we evaluated the renal protective effect of isoflavone. We investigated the role of the PPARγ in the pathogenesis of the disease. For this study, we used diabetic female rats in a postmenopausal model through ovariectomy. The animals were treated with isoflavone or 17β-estradiol. A dosage was administered to bring on blood glycemia, and through immunohistochemistry, we evaluated the immunoreactivity of PPARγ in the endometrium and renal tissue. We analyzed the immunoreactivity of renal injury molecule KIM-1 and the collagen and glycogen densities in the kidney. Through bioinformatics analysis, we observed and gene expression under the influence of different glucose doses. In particular, we observed that isoflavone and 17β-estradiol regulate blood glycemia. Renal injury was inhibited by isoflavone, observed by a reduction in KIM-1, along with glycogen accumulation. These benefits of isoflavone may be associated with PPARγ overexpression in the kidneys and endometrium of diabetic ovariectomized rats.

Hydralazine is an antihypertensive that can induce immune-related adverse effects, such as hydralazine-induced lupus and hydralazine-induced antineutrophilic cytoplasmic antibody (ANCA)-associated vasculitis (AAV). AAV involves necrotizing inflammation of small blood vessels, manifesting as fever, malaise, arthralgia, and myalgia, potentially leading to organ failure. Diagnosis includes clinical evaluation, serological testing for ANCA, and histopathological examination, confirmed by necrotizing granulomatous inflammation in affected tissues.

Lattice radiotherapy (LRT) is a type of spatially fractionated radiation therapy (SFRT) that enables the delivery of ablative doses to specific internal regions of large tumoral lesions, while surrounding tissues and nearby critical structures receive significantly lower exposure. This technique relies on a spatial distribution strategy that allows dose levels of radiation to be applied within the tumor in a single session or, alternatively, over the course of five sessions. Over time, LRT has gained attention as a promising method for managing large tumors, especially in cases where conventional treatments may pose higher risks or be less effective, offering the benefit of reduced side effects.

Risankizumab (RZB) is a humanized monoclonal antibody that selectively targets interleukin-23 (IL-23). It has proven particularly effective in treating psoriasis, a common chronic inflammatory skin disease. However, its use remains poorly documented in certain populations, including patients with a history of solid organ transplantation or recent/active malignancy.

The Von Hippel-Lindau disease (VHL) is an autosomal dominant condition characterized by multiple cystic tumors in several organs, including the pancreas. The symptoms are variable, and suspicion must be raised with typical lesions, such as a hemangioblastoma of the central nervous system (CNS) or retina, associated with a renal cell carcinoma, a pheochromocytoma or multiple pancreatic cysts, besides neuroendocrine tumors (NET). The diagnosis in a patient without a family history should be suspected in case of a hemangioblastoma of the CNS and/or retina, which could also be associated with other lesions, such as pancreatic cysts and NETs.

Background Chronic kidney disease is a major global health problem, significantly increasing the risk of cardiovascular complications compared to the general population. This study aimed to evaluate vascular aging in patients with end-stage renal disease treated with hemodialysis or peritoneal dialysis by analyzing clinical and laboratory parameters and carotid intima-media thickness (CIMT), with the goal of identifying predictors of carotid disease and comparing the prevalence between groups. Methods We conducted a retrospective cohort study that included 59 subjects with end-stage renal disease who were treated with renal replacement therapy: peritoneal dialysis (29 subjects) and hemodialysis (30 subjects).
