Prognostic accuracy of Whole Lung Perfusion Blood Volume as a predictor of 28-day Mortality in Acute Pulmonary Thromboembolism - A prospective study.

Background: The estimated incidence of pulmonary embolism (PE) is around 60-70 cases per 100,000 people annually. The overall mortality rate for massive PE is substantial, ranging from 18% to 65%. We can utilise changes in lung perfusion to stratify patients with PE acutely based on risk, highlighting its diagnostic and prognostic value.

Comparing immunogenicity and safety following transition from reference rituximab to biosimilar rituximab (DRL_RI) in patients with rheumatoid arthritis: a randomized, double-blind, phase 3 study.

Objectives: To assess immunogenicity and safety in patients with active rheumatoid arthritis (RA) transitioning from rituximab [US-licensed rituximab: Reference Product (RP); EU-approved rituximab: Reference Medicinal Product (RMP)] to DRL_RI (proposed rituximab biosimilar), in comparison to those continuing on RP/RMP.

Methods: This double-blind, randomized, Phase 3 study included 140 RA patients having prior exposure to RP/RMP; transitioned to DRL_RI (n = 70) or continued with RP/RMP (n = 70) for two 1000 mg infusions on Days 1 and 15. Assessments included Time-matched Rituximab Concentration (TMRC), anti-drug antibodies (ADAs), neutralizing antibodies (NAbs) and ADA titre over 12 weeks, and safety follow-up till 26 weeks.

Enhancement to effusion: Breast implant-associated anaplastic large cell lymphoma.

Unlabelled: This case is a rare presentation of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL), where malignant pericardial effusion (MPE) served as the primary manifestation. A 58-year-old woman, post-breast implant removal, presented with pleuritic chest pain, fever, and chills. Clinical evaluation revealed jugular venous distention, muffled heart sounds, and hemodynamic instability.

Characterization of a novel subfamily 1.4 lipase from Bacillus licheniformis IBRL-CHS2: Cloning and expression optimization.

This study focuses on a novel lipase from Bacillus licheniformis IBRL-CHS2. The lipase gene was cloned into the pGEM-T Easy vector, and its sequences were registered in GenBank (KU984433 and AOT80658). It was identified as a member of the bacterial lipase subfamily 1.
