Small-cell lung cancer accounts for about 15% of lung cancers with an extremely poor prognosis. The incorporation of immunotherapy to platinum-based chemotherapy offers sustained overall survival benefits and become the standard for the first-line setting of extensive-stage small-cell lung cancer. However, only a limited number of patients derive prolonged benefits.

Human-induced pluripotent stem cell (hiPSC) technology has been applied in pathogenesis studies, drug screening, tissue engineering, and stem cell therapy, and patient-specific hiPSC-derived cardiomyocytes (hiPSC-CMs) have shown promise in disease modeling, including diabetic cardiomyopathy. High glucose (HG) treatment induces lipotoxicity in hiPSC-CMs, as evidenced by changes in cell size, beating rate, calcium handling, and lipid accumulation. Empagliflozin, an SGLT2 inhibitor, effectively mitigates the hypertrophic changes, abnormal calcium handling, and contractility impairment induced by HG.

Department of Cardiovascular Medicine, Dokkyo Medical University, 880 Kitakobayashi, Mibu, Shimotsugagun, Tochigi, 321-0293, Japan.
Background: The conventional mapping approach for the atrioventricular accessory pathway (AP) involves point-by-point mapping to identify the connection sites of the AP to the atria or ventricle and accurate interpretation of local electrograms. Omnipolar mapping technology (OMT) explains how vector and wave speed are produced by using both unipolar and bipolar signals to obtain omnipolar signals, directions, and conduction velocity. The aim of this study is to verify the effectiveness of OMT for catheter ablation of AP.

Pediatr Emerg Care
January 2025
Department of Emergency Medicine, Columbia University Irving Medical Center, New York, NY.
Objective: Entrustment describes the balance of supervision and autonomy between resident and preceptor to complete doctoring tasks like procedures. Entrustment alignment between resident and preceptor facilitates safe, successful outcomes, and promotes learning. Study objectives describe procedural entrustment alignment between senior pediatric residents and their preceptors and report the impact of a simulation-based formative assessment (SFA) on entrustment alignment.

December 2024
Department of Clinical Research, University of San Luis Potosí, San Luis Potosí, MEX.
Background: In large-scale molecular studies, a protocol that generates high yields and quality DNA for future polymerase chain reaction (PCR) assays is needed. The collection of buccal cells by cytobrush may represent an efficient, noninvasive, and inexpensive method for obtaining genetic material from school populations. The aim of this study was to develop a method to obtain genomic DNA from buccal cells of schoolchildren, and the DNA was extracted immediately after collecting the buccal cell samples and after storing the samples for 8 months at -20 °C to establish the feasibility of the method for epidemiological studies.
