Potentiating CD20 monoclonal antibody therapy by targeting complement C3 fragment covalently deposited on lymphoma cells.

Monoclonal antibodies (mAbs) improve survival of patients with mature B-cell malignancies. Fcγ-receptor dependent effector mechanisms kill tumor cells but can promote antigen loss through trogocytosis, contributing to treatment failures. Cell-bound mAbs trigger the complement cascade to deposit C3 activation fragments and lyse cells.

ARISCAT and LAS VEGAS risk scores for predicting postoperative pulmonary complications after cardiac surgery: a cohort study.

Background: Postoperative pulmonary complications (PPCs) could lead to morbidity, mortality, and prolonged hospital stay. Different risk-scoring systems are used to predict the identification of patients at risk of developing PPCs. The diagnostic accuracies of the Assess Respiratory Risk in Surgical Patients in Catalonia (ARISCAT) and Local Assessment of Ventilatory Management During General Anaesthesia for Surgery (LAS VEGAS) risk scores are compared in prediction of PPCs taking pulmonary complication as the gold standard in cardiac surgery.

Microliter Whole Blood Neutrophil Assay Preserving Physiological Lifespan and Functional Heterogeneity.

For in vitro neutrophil functional assays, neutrophils are typically isolated from whole blood, having the target cells exposed to an artificial microenvironment with altered kinetics. Isolated neutrophils exhibit limited lifespans of only a few hours ex vivo, significantly shorter than the 3-5 day lifespan of neutrophils in vivo. In addition, due to neutrophils' inherently high sensitivity, neutrophils removed from whole blood exhibit stochastic non-specific activation that contributes to assay variability.

Mapping of uncontrolled dumpsites in arid regions through remote sensing and image processing.

Due to increased urbanization, the development of new areas, construction of new houses and buildings and uncontrolled dumpsites (UDSs) are becoming a challenge facing local authorities in Saudi Arabia. UDSs pose health risks to the public, potentially deteriorating the environment around them and reducing the value of ongoing development areas. The local municipalities rely on field surveys and citizen reports.

Thrombectomy Outcomes in Acute Basilar Artery Occlusions Due to Intracranial Atherosclerotic Disease.

Background And Objectives: Intracranial atherosclerotic disease (ICAD) large vessel occlusion (LVO) is responsible for up to 30% of LVO. In this study, we aimed to determine the likelihood of favorable functional outcomes (modified Rankin Scale 0-3) in acute ICAD-LVO basilar occlusion compared with embolic basilar occlusion.

Methods: This is an analysis of the Posterior Circulation Ischemic Stroke Evaluation: Analyzing Radiographic and Intraprocedural Predictors for Mechanical Thrombectomy Registry in which patients with acute basilar artery occlusions from 8 comprehensive stroke centers were included from 2015 to 2021.

Endovascular Therapy in the Extended Time Window for Large Vessel Occlusion in Patients With Pre-Stroke Disability.

Background And Purpose: We compared the outcomes of endovascular therapy (EVT) in an extended time window in patients with large-vessel occlusion (LVO) between patients with and without pre-stroke disability.

Methods: In this prespecified analysis of the multinational CT for Late Endovascular Reperfusion study (66 participating sites, 10 countries between 2014 and 2022), we analyzed data from patients with acute ischemic stroke with a pre-stroke modified Rankin Scale (mRS) score of 0-4 and LVO who underwent EVT 6-24 hours from the time last seen well. The primary outcome was the composite of functional independence (FI; mRS score 0-2) or return to the pre-stroke mRS score (return of Rankin, RoR) at 90 days.
