Cardiac organoids offer sophisticated 3D structures that emulate key aspects of human heart development and function. This review traces the evolution of cardiac organoid technology, from early stem cell differentiation protocols to advanced bioengineering approaches. We discuss the methodologies for creating cardiac organoids, including self-organization techniques, biomaterial-based scaffolds, 3D bioprinting, and organ-on-chip platforms, which have significantly enhanced the structural complexity and physiological relevance of cardiac models.

Background And Objective: Accurate prediction of perioperative major adverse cardiovascular events (MACEs) is crucial, as it not only aids clinicians in comprehensively assessing patients' surgical risks and tailoring personalized surgical and perioperative management plans, but also for information-based shared decision-making with patients and efficient allocation of medical resources. This study developed and validated a machine learning (ML) model using accessible preoperative clinical data to predict perioperative MACEs in stable coronary artery disease (SCAD) patients undergoing noncardiac surgery (NCS).

Methods: We collected data from 9171 adult SCAD patients who underwent NCS and extracted 64 preoperative variables.

Background: Temporal trends and risk factors of perioperative cardiac events (PCEs) in patients over 80 years old with coronary artery disease (CAD) undergoing noncardiac surgery are still unclear.

Methods: We retrospectively reviewed 1478 patients over 80 years old, with known CAD undergoing selective noncardiac surgery in a single center (2014-2022). Patients were divided into three equal time groups based on the discharge date (2014-2016, 2017-2019, and 2020-2022), with 367, 473, and 638 patients in Groups 1-3, respectively.

Most cases of hepatocellular carcinoma (HCC) are able to be diagnosed through regular surveillance in an identifiable patient population with chronic hepatitis B or cirrhosis. Nevertheless, 50% of global cases might present incidentally owing to symptomatic advanced-stage HCC after worsening of liver dysfunction. A systematic search based on PUBMED was performed to identify relevant outcomes, covering newer surveillance modalities including secretory proteins, DNA methylation, miRNAs, and genome sequencing analysis which proposed molecular expression signatures as ideal tools in the early-stage HCC detection.

Three anionic metal-organic frameworks (MOFs) {[Zn(BTEC)(HO)(4-BCBPY)]·(HO)} (1-3) (BTEC = 1,2,4,5-benzenetetracarboxylic acid anion, 4-BCBPY = 1,1'-bis(4-cyanobenzyl)-4,4'-bipyridinium dication) were synthesized in the reaction of 1,2,4,5-benzenetetracarboxylic acid with different metal salts such as ZnNO, ZnCl, and ZnSO, under solvothermal conditions in the presence of 1,1'-bis(4-cyanobenzyl)-4,4'-bipyridinium chloride. Single crystal X-ray diffraction analysis shows that compounds 1, 2 and 3 have MOF structures based on binuclear metal building units, which are connected by two protonated BTEC ligands and three zinc ions, and the viologen cation 4-BCBPY is located in the channel to achieve charge balance. Compounds 1, 2 and 3 have good photosensitivity, respond to sunlight, UV light and blue ray, and turn blue.

Myocarditis is a disease characterized by localized or diffuse inflammation of the myocardium without efficient treatment. This study explored the regulatory mechanism of microRNA-133 (miR-133) secreted from bone marrow mesenchymal stem cell-derived exosome (BMSC-Exo) on myocardial fibrosis and epithelial-mesenchymal transition (EMT) in viral myocarditis (VMC) rats through regulating mastermind-like 1 (MAML1). BMSCs in rats were isolated and cultured to identify their immune phenotype and osteogenic and adipogenic ability, and BMSC-Exo were extracted and identified.

Article Synopsis
  • Researchers aimed to investigate genomic mutations in gallbladder carcinoma (GBC) to understand their role as therapeutic targets and identify potential treatment strategies.
  • Whole-exome sequencing was performed on 157 GBC patients, revealing recurrent mutations that correlated with poor patient outcomes and contributed to tumor growth through specific signaling pathways.
  • Treatment with ERBB2/ERBB3 inhibitors and PD-L1 blockers showed promise in reversing tumor growth and improving immune response, suggesting these mutations could help identify patients who might benefit from targeted therapy.
