Article Synopsis
- The study develops high yttrium-content phosphate-based glass-ceramic microspheres for use in bone cancer radiotherapy, showcasing their production through flame spheroidization and resulting in a narrow size distribution (45-125 μm).
- Energy dispersive X-ray (EDX) analysis indicates an increase in yttrium content in the microspheres with higher yttrium oxide ratios, while showing a uniform distribution and a decrease in phosphate, calcium, and magnesium levels.
- In vitro tests reveal that these microspheres exhibit good cytocompatibility, with enhanced cellular responses compared to earlier P40 glass microspheres, highlighting their potential as biomaterials for cancer treatment.
Burnout is a significant issue among healthcare professionals, particularly nurses, due to high workloads and emotional demands. However, limited research has explored burnout among primary healthcare nurses in Saudi Arabia, who play a vital role in healthcare delivery. This study aims to address this gap by investigating burnout levels and their association with anxiety, depression and self-efficacy among primary healthcare nurses.

- Two-dimensional TiC MXene is gaining attention as a lithium-ion battery electrode due to its excellent ion transport and lithium absorption capabilities.
- A molecular dynamics simulation study shows that TiC MXene exhibits better tensile strength and elasticity along zigzag directions, while armchair-oriented TiC MXene demonstrates greater fracture strain under certain conditions.
- The study highlights that temperature and strain rate affect the material's mechanical properties differently, and the presence of carbon vacancies significantly weakens the elastic modulus of TiC MXene.
Background: It is controversial whether pulmonary function testing should be performed routinely in cardiac surgery patients. The aim of our study was to focus on patients who have congestive heart failure, caused by left ventricular dysfunction or left-sided heart valve disease, and study the prognostic value of performing preoperative pulmonary function testing on their postoperative outcomes.
Methods: This is a retrospective propensity score matched study that included 366 patients with congestive heart failure who underwent cardiac surgery and had preoperative pulmonary function test.
Article Synopsis
- This study focused on acute myocardial infarction complicated by cardiogenic shock (AMI-CS) in the Gulf region, addressing a lack of data by analyzing 1,513 patients from 2020 to 2022.
- The incidence of AMI-CS was found to be 4.1%, with a high in-hospital mortality rate of 45.5%, and patients primarily presented with ST-elevation MI.
- Key risk factors for increased hospital mortality included previous coronary artery bypass grafts, chronic kidney disease, and SCAI shock stages D and E, with a 12-month survival rate of 51.49%.*
