Serum creatinine to cystatin C ratio in relation to heart failure with preserved ejection fraction.

Background: Sarcopenia was recognized to be one of the common comorbidities in heart failure (HF). The sarcopenia index (SI), based on serum creatinine to cystatin C ratio, was developed as a simple tool to evaluate skeletal muscle mass but has not been well-studied in the correlation of left ventricular ejection fraction (LVEF). The aim of this study is to analyze the SI in patients with HF, especially patients with HF with preserved ejection fraction (HFpEF), and to develop a prediction model for HFpEF.

Unexpected pheochromocytoma leading to cardiac arrest during the perioperative period: a case report and literature review.

Background: Pheochromocytomas (PCCs) are rare neuroendocrine catecholamine (CA)-secreting tumours that originate from chromaffin tissue and can produce and store CAs. Unexpected PCCs pose a serious threat to the perioperative safety of patients and a considerable challenge to anaesthesiologists because of the risks of fatal hypertensive crises and other stresses.

Case Presentation: A 37-year-old woman who was scheduled for tonsillectomy and palatopharyngoplasty under general anaesthesia experienced a malignant cardiovascular event after induction, which was characterized mainly by a sharp increase in heart rate and blood pressure, ultimately leading to cardiac arrest and the occurrence of secondary long QT syndrome.

This study aimed to investigate the function of TFAM and its regulatory molecular mechanism in the progression of AILI.

Buried hole-selective interface engineering for high-efficiency tin-lead perovskite solar cells with enhanced interfacial chemical stability.

Mixed Sn-Pb perovskites are attracting significant attention due to their narrow bandgap and consequent potential for all-perovskite tandem solar cells. However, the conventional hole transport materials can lead to band misalignment or induce degradation at the buried interface of perovskite. Here we designed a self-assembled material 4-(9H-carbozol-9-yl)phenylboronic acid (4PBA) for the surface modification of the substrate as the hole-selective contact.
