Background A soft tissue defect resulting from a diabetic heel ulcer can be difficult to address due to limited reconstructive options and unique local area demand. The medial plantar artery flap is ideal for heel defect coverage as it provides a thick glabrous skin with good sensory feedback. The prerequisite of medial plantar artery flap surgery is a patent medial plantar artery, which is a branch of the posterior tibial artery (PTA).

  • CTPA is the preferred method for diagnosing pulmonary embolism (PE), but it comes with risks like radiation exposure and kidney issues.
  • A study at a Malaysian hospital reviewed 351 CTPA cases, finding a 26.5% positive yield for PE, with factors such as gender and medical history influencing the results.
  • Male patients were more likely to test positive for PE, while those with COVID-19 and pneumonia had lower chances of a positive CTPA, suggesting that doctors should be cautious when ordering these scans for such patients.

As unitised regenerative proton exchange membrane fuel cell (URPEMFC) is progressing in terms of its performance, more emphasis should be placed on the understanding of the interaction between multiphase reactants and products and its effect during the switching mode. A 3D transient computational fluid dynamics model was utilised in this study to simulate the supply of liquid water into the flow field when the system switched from fuel cell mode to electrolyser mode. Different water velocities were investigated to identify their effect on the transport behaviour under parallel, serpentine, and symmetry flow fields.

  • Anaplastic lymphoma kinase (ALK) inhibitors are effective for ALK-positive metastatic non-small cell lung cancer (NSCLC), but access is limited in developing countries like Malaysia due to financial constraints.
  • A study analyzed 65 ALK-positive NSCLC patients from 18 Malaysian hospitals, finding that most received crizotinib, the most common ALK inhibitor, and showed improved overall survival (OS) compared to those on chemotherapy.
  • Although ALK inhibitors led to a longer median time on treatment (TOT) and OS, the results were not statistically significant likely due to the small sample size.

Background: In New Zealand little nursing or medical curricula time, if any, is specifically devoted to the enhancement of empathy. If being empathic is important in the context of patient care, it is a quality that is already present in students or is learned by students during their practicum in the company of experienced clinicians. This study aimed to compare self-reported empathy ratings between different groups of medical students and one cohort of nursing students who were either exposed or not exposed to explicit empathy training or learning in clinical settings in the presence of patients.
