Left Ventricular Hypertrophy Geometry and Vascular Calcification Co-Modify the Risk of Cardiovascular Mortality in Patients with End-Stage Kidney Disease: A Retrospective Cohort Study. J Atheroscler Thromb 2023; 30:1242-1254. [PMID: 36567124 PMCID: PMC10499460 DOI: 10.5551/jat.63870] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Accepted: 11/01/2022] [Indexed: 12/25/2022] Open
Abstract
AIM Patients with end-stage kidney disease (ESKD) have an unparalleled risk of left ventricular hypertrophy (LVH) and vascular calcification (VC), both of which introduce excessive cardiovascular risk. However, it remains unclear whether LVH geometry co-modulates cardiovascular outcomes with VC in this population. METHODS A retrospective cohort study was conducted. Patients with ESKD requiring chronic hemodialysis were identified from Shin Kong Wu Ho-Su Memorial Hospital between October and December 2018, with echocardiographic LVH geometry and aortic arch calcification (AoAC) determined. They were divided into four groups according to AoAC severity and eccentric or concentric LVH. We used Kaplan-Meier analysis and Cox proportional hazard regression to analyze their cardiovascular and all-cause mortality after multivariate adjustment. RESULTS Overall, 223 patients with ESKD with LVH were analyzed, among whom 29.1%, 23.3%, 25.1%, and 22.4% had non-to-mild AoAC with eccentric and concentric LVH and moderate-to-severe AoAC with eccentric and concentric LVH, respectively. After 3.5 years of follow-up, patients with ESKD with moderate-to-severe AoAC and concentric LVH had a significantly higher risk of cardiovascular mortality than those with non-to-mild AoAC and eccentric LVH (hazard ratio 3.35, p=0.002). However, those with moderate-to-severe AoAC but eccentric LVH did not have higher cardiovascular mortality. Similarly, patients with ESKD with moderate-to-severe AoAC and concentric LVH had a significantly higher all-cause mortality than those with non-to-mild AoAC and eccentric LVH, whereas the other two groups did not have higher risk. CONCLUSION LVH geometry could help stratify the risk of patients with ESKD when they had severe VC, and co-existing severe VC and concentric LVH aggravated cardiovascular risk.

Abstract
Dietary intervention is crucial for the prevention and control of diabetes. China has the largest diabetic population in the world, yet no one dietary strategy matches the eating habits of the Chinese people. To explore an effective and acceptable dietary pattern, this study uses oat and buckwheat compound (OBC) as a staple food substitute and explored its effects on diabetic Sprague–Dawley rats. The model of diabetic rats was established by combining high-calorie feed and streptozotocin (STZ) injection. The dietary intervention for the seven groups, including a normal control group, a model control group, a metformin control group, a wheat flour control group, and three OBC groups with different doses, started from the beginning of the experiment and lasted for 11 weeks, two consecutive injections of STZ in small doses were operated at the 6th week. General states, glucose metabolism, and lipid metabolism indexes were measured. Antioxidant and inflammatory indexes and pathologic changes of kidney and liver tissues were tested. Changes in kidney and ileum ultramicrostructure were detected. What's more, ileal epithelial tight junction proteins and gut microbiota were analyzed. Significant decreases in fasting blood glucose (FBG), glucose tolerance, serum insulin, and insulin resistance were observed in rats intervened with OBC, and these rats also showed a higher level of superoxide dismutase (SOD) together with improved lipid metabolism, attenuated inflammation, and liver and kidney injuries. In addition, in OBC groups, the intestinal barrier was improved, and the disturbance of gut microbiota was reduced. These results suggest that OBC has health-promoting effects for diabetic rats, and since oat and buckwheat are traditionally consumed grains in China, OBC could be a potential and easy-to-accept staple food substitute for the dietary pattern for Chinese.

Abstract
BACKGROUND The current treatment for allergic rhinitis (AR) is inadequate. OBJECTIVE The present study aimed to investigate the therapeutic effect of taurine on AR and to identify the underlying molecular mechanisms. METHODS The serum level of the antioxidant enzyme extracellular superoxide dismutase (SOD3) was determined in AR patients and in healthy controls. The antiallergic inflammatory effects of taurine were evaluated in a dinitrophenyl-human serum albumin (DNP-HSA)-stimulated human mast cell line (HMC-1) and in an ovalbumin (OVA)-induced AR mouse model. RESULTS Clinically, a reduction in serum level of SOD3 was observed in AR patients. Taurine treatment led to dose-dependent increases in SOD3 at both protein and mRNA levels in HMC-1 cells. SOD3 production was regulated by peroxisome proliferator-activated receptor-γ (PPAR-γ) in response to taurine. SOD3 overexpression inhibited the release of proinflammatory cytokines including tumor necrosis factor-α (, interleukin (IL)-4, and IL-6. Its overexpression also ameliorated the loss of interferon-γ. SOD3 and PPAR-γ influenced inflammatory cytokine production via regulation of the phosphorylation of extracellular signal-regulated kinase 1/2 (ERK1/2). An OVA-induced AR animal model study showed that taurine was efficacious in alleviating allergic inflammatory reactions by relieving behavior symptoms of AR mice and reducing eosinophilic and mast cell infiltration into the nasal cavity. In addition, taurine treatment increased the production of SOD3 and PPAR-γ, which, in turn, suppressed expression of proinflammatory cytokines through phosphorylation of ERK1/2. CONCLUSION Taurine could potentially serve as a therapeutic treatment for allergic disorders.

Abstract
Diabetic nephropathy (DN) is one of the most common microvascular complications associated with diabetes mellitus (DM); the incidence has been predicted to reach 7.7% by 2030 on a global scale. Krüppel-like factor 5 (KLF5) is involved in numerous important biological processes; however, the potential effects of KLF5 on podocytes in patients with diabetic nephrotic (DN) have not yet been investigated. In the present study, synaptopodin expression in podocytes was investigated using an immunofluorescence assay. Following this, the proliferation of podocytes was investigated using an MTT assay. In addition, KLF5 was overexpressed in podocytes, and cell cycle arrest and apoptosis was subsequently investigated using flow cytometry. Western blotting and reverse transcription-quantitative polymerase chain reaction assays were performed to detect the expression levels of genes involved in the cell cycle and apoptosis, and the extracellular signal-regulated protein kinase (ERK)/p38 mitogen-activated protein (MAP) kinase pathway. The results demonstrated that treatment with puromycin aminonucleoside (PAN) suppressed the proliferation of podocytes in a dose- and time-dependent manner, and overexpression of KLF5 induced cell cycle arrest of podocytes regulated by PAN. Furthermore, overexpression of KLF5 was revealed to have inhibited PAN-induced apoptosis of podocytes, and that overexpression of KLF5 suppressed the ERK/p38 MAP kinase pathway in podocytes induced by PAN. Therefore, the results of the present study suggested that KLF5 may represent a potential therapeutic target for treatment of patients with DN.

Abstract
BACKGROUND We aimed to evaluate the potential benefits of N-acetylcysteine (NAC) on the risk of chronic kidney disease (CKD) progression to dialysis-requiring end-stage renal disease (ESRDd). METHODS In a population-based cohort study of 145,062 individuals, 123,608 CKD patients who were followed up for 10years were included, and CKD patients treated with NAC (ICD-9-CM) were compared with those who were not treated. Using propensity score matching, we analyzed the predictors of CKD progression to ESRDd by Cox proportional hazards regression with adjustments for sex, age, and comorbidities, and evaluated the effect of NAC using cumulative defined daily dose (cDDD). RESULTS NAC use was associated with a reduced risk for progression to ESRDd [hazard ratio (HR), 0.819; 95% confidence interval (CI), 0.781-0.965; P=0.017]. Risk reduction was proportional to cDDD in NAC users compared with that in NAC non users (HR, 0.835, 0.811, and 0.799 for cDDD 91-180, 181-360, and >360, respectively; P for trend=0.018). Risk reduction was apparent in women (P=0.001) and in younger-aged patients of 18-29years (P=0.021) and 30-39years (P=0.033), in the presence of hypertension (P=0.003), and in the absence of diabetes mellitus (P=0.042) and congestive heart failure (P=0.036). CONCLUSION NAC use was associated with a reduced risk for progression to ESRDd. These results, obtained from retrospective data, indicate that a prospective study is warranted.
