Background: The aim was to identify the restorative dentist, knowledge and application of Antimicrobial photodynamic therapy (aPDT) in dental practice; and to provide an overview of the potential challenges faced by restorative dentists (RD) in Saudi Arabia.
Methods: A 15-item cross sectional study questionnaire was distributed through online portal to assess the knowledge, and practice of RD towards aPDT and its practice. The questionnaire consisted of 3 sections, exploring the demographics of participants, knowledge, application and perception of aPDT using yes/no response and Likert scale. Response means, frequencies, and chi-square tests to compare subgroups based on gender, education level, and practice experience.
Results: Out of 500 participants, 375 completed the survey forms (75% response rate). The majority was male (68%) with a mean age of 46 years. Respondents demonstrated a moderate level of knowledge (60.5%). Only 33% expressed confidence in aPDT as a standalone treatment, while 67% showed limited referrals to specialists. However, 88.5% expressed interest in receiving training and attending workshops for aPDT therapy. Education and experience significantly influenced overall knowledge question responses (p = 0.031).
Conclusion: Majority of restorative dentists demonstrated a moderate understanding of the role of aPDT in dentistry. More than two thirds of respondents (77%) believed that aPDT is an effective adjuvant therapy. Increased experience (> 10 years) and education (Post-graduates) showed higher application of aPDT. The study reveals the potential for incorporating aPDT knowledge into restorative dental practices, particularly among general dentists.

Introduction: Artificial intelligence technology has a wide range of application prospects in the field of medical education. The aim of the study was to measure the effectiveness of ChatGPT-assisted problem-based learning (PBL) teaching for urology medical interns in comparison with traditional teaching.
Methods: A cohort of urology interns was randomly assigned to two groups; one underwent ChatGPT-assisted PBL teaching, while the other received traditional teaching over a period of two weeks.

Article Synopsis
- Immune checkpoint therapies have revolutionized cancer treatment but face challenges like low response rates and drug resistance, highlighting the need for a better understanding of the tumor microenvironment (TME).
- Recent studies show that biomechanical forces within the TME significantly impact immune responses and tumor progression, indicating that manipulating these forces could enhance immune activation against tumors.
- The review discusses key biomechanical mechanisms, the role of the extracellular matrix, and potential clinical applications, aiming to provide insights for discovering new therapeutic targets.

Glioblastoma (GBM) is a highly aggressive adult brain cancer, characterised by poor prognosis and a dismal five-year survival rate. Despite significant knowledge gains in tumour biology, meaningful advances in patient survival remain elusive. The field of neuro-oncology faces many disease obstacles, one being the paucity of faithful models to advance preclinical research and guide personalised medicine approaches.

The potential of large language models (LLMs) in medical applications is significant, and Retrieval-augmented generation (RAG) can address the weaknesses of these models in terms of data transparency and scientific accuracy by incorporating current scientific knowledge into responses. In this study, RAG and GPT-4 by OpenAI were applied to develop GuideGPT, a context aware chatbot integrated with a knowledge database from 449 scientific publications designed to provide answers on the prevention, diagnosis, and treatment of medication-related osteonecrosis of the jaw (MRONJ). A comparison was made with a generic LLM ("PureGPT") across 30 MRONJ-related questions.

Advances in molecular genetics during the past decades led to seminal discoveries in the genetic basis of cardiovascular diseases, resulting in a new understanding of their pathogenesis, determinants of natural history and more recently paved the way for innovative therapies. A significant gap, however, exists between the rapidly increasing knowledge, especially of cardiovascular Mendelian disorders, and the medical applications in daily practice. This paper will focus on the practical issues the cardiologist may be faced with when suspecting a Mendelian disorder.
