Role of a Home-visit Nursing Agency in Supporting Patients with Heart Failure on Continuous Catecholamine Infusion: A Case Series Study.

Aim: This study aimed to discuss the role of home-visit nurses in managing continuous catecholamine infusion in patients with heart failure by investigating the outcome of patients and the home-visit nursing intervention.

Methods: We conducted a retrospective, case series study of eight patients with heart failure who underwent home-based continuous catecholamine infusion between April 2016 and March 2024. Data including the patients' demographics, the duration of continuous catecholamine infusion, the frequency of nursing and emergency nursing visits, and patients' endpoints were collected.

[Long-term Reproducibility Evaluation of Fluoroscopy Dose Rate in Angiography Equipment].

Purpose: Diagnostic reference levels (DRLs) are defined as fluoroscopic dose rate measurements that are used for patient dose management in angiography. It is recommended that DRLs be measured at least once a year. This study aimed to evaluate the long-term fluctuations of fluoroscopic dose rate in an angiography system.

Synthesis of 2-Amino-4-arylazulenes from 8-Aryl-2-cyclohepta[]furan-2-ones and Transformation into 6-Aryl-7-naphth[3,2,1-]azulen-7-ones.

2-Amino-4-arylazulene derivatives were prepared from 8-aryl-2-cyclohepta[]furan-2-ones, which were converted into 6-aryl-7-naphth[3,2,1-]azulen-7-ones through a several step process. The reaction of 8-aryl-2-cyclohepta[]furan-2-ones bearing an ester group at the 3-position with malononitrile in the presence of triethylamine afforded 2-amino-4-arylazulenes. The prepared 2-amino-4-arylazulenes were converted to the corresponding 2-chloro derivatives by the Sandmeyer reaction, which were subsequently transformed into 2,4-diarylazulenes by Suzuki-Miyaura coupling with various aryl boronic acids.

Anesthetic management of a patient with mandibular hypoplasia, deafness, progeroid features, lipodystrophy syndrome: a case report.

Background: Mandibular hypoplasia, deafness, progeroid features, and lipodystrophy (MDPL) syndrome is a rare autosomal dominant disorder that presents unique challenges for anesthetic management due to its multisystemic manifestations. This report outlines the anesthetic considerations for MDPL patients based on our case experience.

Case Presentation: A 15-year-old male with MDPL syndrome underwent testicular extraction under general anesthesia.

Peripheral venous dilation using flow-mediated dilation response: A randomized crossover study.

Background: Venodilation is crucial in enhancing the success rate of peripheral intravenous cannulation. Flow-mediated dilation (FMD) is a vasodilatory response initiated by temporary ischemia followed by reperfusion. This crossover study aimed to test the hypothesis that FMD induces dilation of the peripheral veins of the forearm.
