Revascularization therapies, such as percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG), alleviate symptoms and treat myocardial ischemia. Patients with multivessel disease, particularly those undergoing 3-vessel PCI, are more susceptible to procedural complications, which can increase healthcare costs. Developing efficient strategies for resource allocation has become a paramount concern due to tightening healthcare budgets and the escalating costs of treating heart conditions.

Background: Rheumatoid arthritis (RA) is a chronic autoimmune disease that causes joint damage and progressive destruction of adjacent cartilage and bones. Quick and accurate detection of rheumatoid factors (RF) and anti-cyclic citrullinated peptide antibodies (anti-CCP) in serum is effective in diagnosing RA and preventing its progression. However, current methods for detecting these two biomarkers are costly, time-consuming, labor-intensive, and require specialized equipment.

Article Synopsis
  • Cerebral ischemic stroke is a leading cause of disability in adults, and previous studies showed that human Wharton's jelly mesenchymal stromal cells (WJ-MSCs) can help reduce neuronal damage in stroke models.
  • This research explored the effects of WJ-MSC exosomes (Exo) in both cell and rat models of stroke, finding that Exo administration significantly protected neurons from glutamate-induced damage.
  • Rats treated with Exo after a stroke showed improved motor function, reduced brain damage, and increased levels of neuroprotective and anti-apoptotic factors in their brains, indicating that WJ-MSC Exo could be a promising stroke treatment.

Transition metal dichalcogenides (TMDs) are 2D materials in which the layers are stacked together by van der Waals forces. Although TMDs are expected to be promising for electronic applications, forming a uniform electrode on them is challenging because of the low adhesion forces between metals and TMDs. This study focuses on improving the quality of metal electrodes by introducing atomic H to create surface defects, using Ni on WS as an example.

Introduction: EGFR tyrosine kinase inhibitors (TKIs) are the standard therapy for non-small-cell lung cancer (NSCLC) patients with EGFR-activating mutations in the first-line setting. Despite initial efficacy, resistance to EGFR-TKIs often develops, and platinum-based chemotherapy is the predominant subsequent treatment. For this study, we aimed to identify prognostic factors for overall survival (OS) and progression-free survival (PFS) among advanced EGFR-mutant NSCLC patients receiving platinum-pemetrexed after progression on EGFR-TKIs.

Background: Repeated transcranial magnetic stimulation (rTMS) could induce alterations in cortical excitability and promote neuroplasticity. To precisely quantify these effects, functional near-infrared spectroscopy (fNIRS), an optical neuroimaging modality adept at detecting changes in cortical hemodynamic responses, has been employed concurrently alongside rTMS to measure and tailor the impact of diverse rTMS protocols on the brain cortex.

Objective: This systematic review and meta-analysis aimed to elucidate the effects of rTMS on cortical hemodynamic responses over the primary motor cortex (M1) as detected by fNIRS.

Article Synopsis
  • Most patients with non-small cell lung cancer (NSCLC) receiving immunochemotherapy are given short-term corticosteroids after immune checkpoint inhibitor (ICI) infusion to prevent side effects, but their impact on immune-related adverse events (irAEs) is unclear.
  • A study examined 252 NSCLC patients, comparing those who received early corticosteroids with those who did not, focusing on the rate of irAEs and treatment discontinuation.
  • Results showed that those in the corticosteroid group had a lower likelihood of permanently discontinuing their ICI treatment due to irAEs, suggesting that early corticosteroids may help in reducing serious side effects.
