Background: Acute aortic dissection (AAD) is very fatal without surgical treatment. Higher serum sodium can increase in-hospital mortality of many diseases; however, the effect of serum sodium on postoperative in-hospital mortality in AAD patients remains unknown.
Methods: We collected a total of 415 AAD patients from January 2015 to December 2019. Patients were classified into four categories (Q1-Q4) according to the admission serum sodium quartile. The cox proportional hazards model evaluated the association between serum sodium and in-hospital mortality. All-cause in-hospital mortality was set as the endpoint.
Results: By adjusting many covariates, cox proportional hazards model revealed the in-hospital mortality risk of both Q3 and Q4 groups was 3.086 (1.242-7.671, P = 0.015) and 3.370 (1.384-8.204, P = 0.007) respectively, whereas the risk of Q2 group was not significantly increased. Univariate and multiple Cox analysis revealed that Stanford type A, serum glucose, α-hydroxybutyrate dehydrogenase and serum sodium were risk factors correlated with in-hospital death in AAD patients.
Conclusion: The study indicates that the admission serum sodium of AAD patients has a vital impact on postoperative hospital mortality.

Background: Sodium-glucose cotransporter-2(SGLT-2) inhibitors are a newer class of antidiabetic drugs with the increased risk of euglycemic diabetic ketoacidosis(EuDKA). Encephalopathy is a rare but life-threatening event of EuDKA. Due to paradoxically normal or slightly elevated serum glucose levels, it's easy to be mimicked by cerebral infarction, structural brain damage, thus leading to delayed diagnosis and causing seriously irreversible brain injury.

Although lithium (LIT) therapy is key in managing bipolar disorder long-term, prolonged use significantly contributes to acquired Nephrogenic Diabetes Insipidus (NDI). This study examined whether combining Silymarin (SIL) with Vitamin C (Vit C) enhances protection against lithium-induced nephrotoxicity in rats, comparing their individual antioxidant effects as well. Rats subjected to Li exposure were provided with a standard commercial diet supplemented with 80 mmol LiCl per kilogram for 28 days.

Objective: The mortality rate of patients undergoing maintenance hemodialysis (MHD) remains high. The C-reactive protein-albumin-lymphocyte (CALLY) index is a novel biomarker that reflects inflammation, nutritional and immune status, all merged into one single derived parameter. No study has yet linked the CALLY index to survival in hemodialysis.

Its prevalence and severity increase in patients with chronic kidney disease (CKD), diabetes mellitus, and heart failure (HF), particularly when compounded by medications like Angiotensin converting inhibitors, Angiotensin receptor blockers, and potassium sparing diuretics.

Background: Many studies have reported the renal outcomes and metabolic consequences after augmentation cystoplasty (AC), however few studies have discussed changes in renal tubular function. The aim of this study was to determine the prevalence of metabolic disturbances, evaluate renal tubular function and 24-hour urine chemistry to evaluate the association between metabolic alterations and urolithiasis after AC.
Methods: We investigated serum biochemistry, blood gas, and 24-hour urinary metabolic profile of children who underwent AC between January 2000 and December 2020.
