Objective In an extremely aging society, it is beneficial to reconsider the value of medical treatment for extremely elderly patients. We therefore focused on the efficacy of statin therapy in extremely elderly patients. This study investigated the efficacy of statins for secondary prevention in patients over 75 years old.

The statin use in patients on hemodialysis remains controversial, and no beneficial effects of statin on the reduction of adverse cardiovascular events have been reported in these patients. This study used stratification analysis to examine the clinical factors in patients on hemodialysis who could benefit from statin for secondary prevention. This prospective multicenter study included 234 consecutive patients on hemodialysis with coronary artery disease who underwent successful reperfusion therapy with percutaneous coronary intervention.

Reactive oxygen species that increase during cardiovascular disease (CVD) react with protein cysteine residues to form a glutathione adduct by S-glutathionylation, which is selectively removed by glutaredoxin-1 (Glrx). We previously showed that S-glutathionylation and Glrx play important roles in mouse models of CVD, such as heart failure and peripheral artery disease models. However, there are few clinical studies on Glrx in CVD.

The echinoderm microtubule-associated protein-like 4 ()-anaplastic lymphoma kinase () fusion gene, a driver mutation in lung carcinoma, is fairly common in lung adenocarcinoma but rare in large cell neuroendocrine carcinoma (LCNEC). Here we report a case of stage IV LCNEC positive for this fusion gene in a patient with a poor performance status (PS) who was effectively treated with alectinib. The patient was a 72-year-old non-smoking man diagnosed as LCNEC with multiple metastases.

Article Synopsis
  • The study investigates the link between renal tubulointerstitial damage and cardiovascular events in patients who have experienced a myocardial infarction (MI), focusing on the role of urinary β2-microglobulin (β2MG) levels as a predictive marker.
  • Among 681 MI patients followed for a median of 6 years, those with lower β2MG levels (<0.319 mg/gCre) had significantly lower rates of cardiac death and MI compared to those with higher levels (5.9% vs. 17.1%).
  • High levels of β2MG were identified as an independent predictor of adverse cardiovascular outcomes, indicating its potential value alongside traditional risk factors like estimated glomerular filtration rate (e
