Characterisation of clinical response and transcriptional profiling of proliferating CD8 T cells in the blood of cancer patients after PD-1 monotherapy or combination therapy.

Objective: Immune checkpoint inhibitors (ICI) that block the programmed cell death 1 (PD-1) pathway have shown promise with limited benefit. We and others have shown in small patient cohorts that an early proliferative CD8 T-cell response in the blood may be predictive of clinical response. However, these studies lack detailed analyses and comparisons between monotherapy and combination therapies.

Background: Preterm birth (< 37 weeks' gestation) alters cerebrovascular development due to the premature transition from a foetal to postnatal circulatory system, with potential implications for future cerebrovascular health. This study aims to explore potential differences in the Circle of Willis (CoW), a key arterial ring that perfuses the brain, of healthy adults born preterm.
Methods: A total of 255 participants (108 preterm, 147 full-term) were included in the analysis.
Comparison of global and regional myocardial blood flow quantification using dynamic solid-state detector SPECT and Tc-99 m-sestamibi or Tc-99 m-tetrofosmin in a routine clinical setting.

Solid-state detector single photon emission computed tomography (SPECT) enables the acquisition of dynamic data for calculation of myocardial blood flow (MBF) and myocardial flow reserve (MFR). Here, we report about our experiences on routine clinical use and robustness using Tc-99 m-sestamibi and Tc-99 m-tetrofosmin. 307 patients underwent dynamic list-mode myocardial perfusion imaging (MPI) and standard static MPI for clinical workup of coronary artery disease on a dedicated cardiac SPECT camera.

Can J Anaesth
January 2025
Outcomes Research Consortium, Houston, TX, USA.
Purpose: Residual neuromuscular blockade can impair postoperative respiratory mechanics, promoting hypoxemia and pulmonary complications. Sugammadex, with its unique mechanism of action, may offer a more effective reversal of neuromuscular blockade and respiratory function than neostigmine. We sought to test the primary hypothesis that children undergoing noncardiac surgery exhibit better initial recovery oxygenation when administered sugammadex than those administered neostigmine.

Background: Cardiac Computed Tomography (CCT) is increasingly used to provide 2D, 3D and 4D information in patients with congenital heart disease of all ages. Historically, negotiated rates for professional and technical fees associated with cardiac imaging were confidential, with variability in professional, technical and global charges, reimbursement and cost to patients for the same current procedural terminology (CPT) code at different institutions. Billing transparency is a key component of both the CARE act passed in 2020 and the Health Care PRICE Transparency Act 2.
