Discriminative Ability of Dynamic Chest Radiography to Identify Left Ventricular Dysfunction.

Background: Dynamic chest radiography (DCR) produces sequential radiographs within a short examination time. It is also inexpensive and only uses a low dose of radiation. Because of the lack of reports of evaluating cardiac function using DCR in humans, we investigated its discriminative ability for left ventricular (LV) dysfunction in a study cohort.

Healthcare resource utilisation and economic burden of patients with adequate and inadequate responses to biological and targeted synthetic disease-modifying antirheumatic drugs for rheumatoid arthritis in Japan.

Objective: To compare healthcare resource utilisation (HCRU) and direct costs between responders versus non-responders to advanced therapies for rheumatoid arthritis (RA).

Methods: Patients initiating ≥1 advanced therapy (October 2018 - September 2019) with ≥1 RA claim (6-month pre-index period), ≥2 RA claims (any period), and ≥12 months follow-up were identified from the Medical Data Vision claims database. HCRU and all-cause and RA-related costs [direct medical, emergency department (ED), laboratory, and pharmacy] were compared between responders and non-responders.

Stepwise Sulfite Reduction on a Dinuclear Ruthenium Complex Leading to Hydrogen Sulfide.

Sulfite reduction by dissimilatory sulfite reductases is a key process in the global sulfur cycle. Sulfite reductases catalyze the 6e reduction of SO to HS using eight protons (SO + 8H + 6e → HS + 3HO). However, detailed research into the reductive conversion of sulfite on transition-metal-based complexes remains unexplored.
