Objective Aortic stenosis (AS) is common among elderly patients. Since transcatheter aortic valve replacement (TAVR) is a less invasive procedure than surgical aortic valve replacement for symptomatic severe AS, super-elderly patients have tended to undergo TAVR. We retrospectively investigated the post-TAVR outcome in super-elderly patients with severe AS. Methods This analysis included 433 patients who underwent TAVR in the University of Wisconsin Hospital and Clinics from 2012 to 2017. Post-TAVR mortality, complications in-hospital, rehospitalization, the New York Heart Association (NYHA) functional class and echocardiographic parameters were compared between patients less then 85 years old (n = 290) and ≥85 years old (n = 143). Results The patients ≥85 years old less frequently had a history of coronary artery disease (73.1% vs. 62.2%, p=0.026) and hypertension (87.2% vs. 77.6%, p=0.012) than younger patients. Furthermore, the patients ≥85 years old had moderate-severe mitral regurgitation more frequently (19.3% vs. 28.7%, p=0.037) at baseline than younger patients. There was no significant difference in in-hospital outcomes between the age groups. The 30-day mortality was worse in patients ≥85 years old than in younger ones (0.7% vs. 3.5%, p=0.042). While there was no significant difference in the long-term mortality between the 2 groups, the estimated 1-year mortality from Kaplan-Meier curves were 9.6% in patients less then 85 years old and 14.9% in patients ≥85 years old. The rate of in-hospital complications, rehospitalization rate, improvement in the NYHA functional class and echocardiographic parameters were comparable between the two groups. Conclusion The outcomes of super-elderly patients after TAVR were acceptable, suggesting that these patients could benefit from TAVR. The association between binge alcohol ingestion and atrial fibrillation (AF), often termed "holiday heart syndrome", has long been recognized. However, the underlying cellular and molecular mechanisms are unknown.Methods and ResultsAn experimental model of binge alcohol-induced AF was developed to elucidate the mechanisms linking acute ethanol exposure to changes in ion channel transcription and AF susceptibility. AF-susceptibility during transesophageal electrical stimulation was enhanced 8 h after, but not immediately or 24 h after, acute alcohol intake. T-type calcium channel (TCC) blockade and calcineurin inhibition diminished the AF-promoting effect of ethanol. Long-term (8-24 h) exposure to ethanol augmented TCC isoform-expression (Ca 3.1 and Ca 3.2) and currents in cardiomyocytes, accompanied by upregulation of the transcription factors, Csx/Nkx2.5 and nuclear factor of activated T-cells (NFAT), in the nucleus, and of phospho-glycogen synthesis kinase 3β (GSK3β) in the cytosol. Inhibition of proteied, but mechanistically enigmatic, "holiday heart syndrome". HDL particles have various anti-atherogenic functions, whereas HDL from atherosclerotic patients was demonstrated to be dysfunctional. One possible mechanism for the formation of dysfunctional HDL is the oxidation of its components. However, oxidized HDLs (Ox-HDLs) remain to be well investigated due to lack of reliable assay systems. We have developed a novel sandwich enzyme-linked immunosorbent assay (ELISA) for Ox-HDL by using the FOH1a/DLH3 antibody, which can specifically recognize oxidized phosphatidylcholine, a major component of HDL phospholipid (HDL-PL). We defined forced oxidation of 1 mg/L HDL-PL as 1 U/L Ox-HDL. We assessed serum Ox-HDL levels of normolipidemic healthy subjects (n=94) and dyslipidemic patients (n=177). The coefficients of variation of within-run and between-run assays were 12.5% and 13.5%. In healthy subjects, serum Ox-HDL levels were 28.5±5.0 (mean±SD) U/L. As Ox-HDL levels were moderately correlated with HDL-PL (r=0.59), we also evaluated the Ox-HDL/HDL-PL ratio, which repr be a useful and easy strategy to evaluate HDL functionality, although the comparison study between this Ox-HDL ELISA and the assay of HDL cholesterol efflux capacity remains to be done. Our results indicated that probucol treatment may be associated with lower Ox-HDL levels.Erdheim-Chester disease (ECD) is a non-Langerhans form of histiocytosis that occurs in systemic organs, such as bone, the central nervous system, cardiovascular system, lungs, and kidneys. We report the case of a 68-year-old woman with a cranial pharyngeal tumor and a bone lesion in the tibia. The case was diagnosed as ECD. Pathological analysis showed the typical feature of foamy macrophage accumulation. The macrophages were positive for CD68, and negative for CD1a and S100. The BRAF V600E mutation was identified. In addition, immunohistochemistry was performed for the detailed characterization of the macrophages. The macrophages had low proliferative activity and an M2-like phenotype, and they expressed colony-stimulating factor-1 receptor (CSF1R) on the cell surface.In situ mantle cell neoplasia (isMCN) and leukemic non-nodal mantle cell lymphoma (nnMCL) are classified as an indolent subtype of mantle cell lymphoma (MCL). The tumor cells of isMCN are restricted to the inner layer of the lymphoid tissue mantle zone, exhibiting an in situ pattern histologically. On the other hand, nnMCL is distributed in the peripheral blood, bone marrow and sometimes the spleen, but lymphadenopathy or systemic organ involvement is rare. We report a case of isMCN in a submandibular lymph node resected from a 65-year-old Japanese male. The tumor cells were positive for cyclin D1 (CCND1) and SOX11 expression, and were restricted to the mantle zone area of the lymph node. However, tumor cells were also detected in the stomach mucosa, bone marrow tissue and peripheral blood, suggesting nnMCL. isMCN and nnMCL may have a partly overlapping disease spectrum, although the correlation between these two subtypes has not been well described. This present case demonstrated characteristics overlapping between isMCN and nnMCL.Membranous nephropathy (MN) is a common glomerular disease that is characterized by diffuse thickening of the glomerular basement membrane, and a common cause of nephrotic syndrome (NS). MN is often accompanied with malignant disease; The solid tumors are commonly associated with MN, whereas hematological malignancies are rarely found in patients with MN. A 68-year-old man with a history of diabetes mellitus visited a hospital with a chief complaint of general fatigue. https://www.selleckchem.com/products/sw-100.html He was previously not diagnosed with any complications of diabetes. Computed tomography revealed a pancreatic tumor, and the pathological findings of the biopsied tumor revealed the tumor was diffuse large B-cell lymphoma (DLBCL). Concurrently, he developed severe proteinuria, hypoalbuminemia, systemic edema and hyperlipidemia, consistent with the diagnosis of NS. The biopsied renal specimen revealed minute spike lesions of glomerular basement membrane, and abnormal lymphocytes infiltrated in the kidney interstitially. Anti-glomerular basement membrane antibody, proteinase-3-/myeloperoxidase antineutrophil cytoplasmic antibody and hepatitis B antigenemia, are absent in the patient.
