Covalent inhibitors of the RAS binding domain of PI3Kα impair tumor growth driven by RAS and HER2.

Genetic disruption of the RAS binding domain (RBD) of PI 3-kinase (PI3K) prevents the growth of mutant RAS driven tumors in mice and does not impact PI3K's role in insulin mediated control of glucose homeostasis. Selectively blocking the RAS-PI3K interaction may represent an attractive strategy for treating RAS-dependent cancers as it would avoid the toxicity associated with inhibitors of PI3K lipid kinase activity such as alpelisib. Here we report compounds that bind covalently to cysteine 242 in the RBD of PI3K p110α and block the ability of RAS to activate PI3K activity.

Myocardial ischaemia following COVID-19: a cardiovascular magnetic resonance study.

The pathophysiology of myocardial injury following COVID-19 remains uncertain. COVID-HEART was a prospective, multicentre study utilising cardiovascular magnetic resonance (CMR) to characterise COVID-related myocardial injury. In this pre-specified analysis, the objectives were to examine (1) the frequency of myocardial ischaemia following COVID-19, and (2) the association between ischaemia and myocardial injury.

Evaluating the quality and readability of ChatGPT-generated patient-facing medical information in rhinology.

Purpose: The artificial intelligence (AI) chatbot ChatGPT has become a major tool for generating responses in healthcare. This study assessed ChatGPT's ability to generate French preoperative patient-facing medical information (PFI) in rhinology at a comparable level to material provided by an academic source, the French Society of Otorhinolaryngology (Société Française d'Otorhinolaryngologie et Chirurgie Cervico-Faciale, SFORL).

Methods: ChatGPT and SFORL French preoperative PFI in rhinology were compared by analyzing responses to 16 questions regarding common rhinology procedures: ethmoidectomy, sphenoidotomy, septoplasty, and endonasal dacryocystorhinostomy.

Identifying Pain Subtypes in Patients With Craniofacial Lesions of Fibrous Dysplasia/McCune-Albright Syndrome.

Background: Fibrous dysplasia/McCune-Albright syndrome (FD/MAS) is a genetic disorder, marked by bone lesions, often affecting the craniofacial skeleton. Pain is a prevalent yet heterogeneous symptom reported by patients with craniofacial FD. Effective treatments are currently lacking, posing a significant clinical challenge to patient care.

Lateral Opening Distal Femoral Osteotomy with Concomitant MPFL Reconstruction is Efficacious in Addressing Patellar Instability.

Purpose: To describe the clinical and radiographic outcomes of patients undergoing a lateral opening distal femur osteotomy (DFO) to address valgus alignment and restore patellar stability.

Methods: A retrospective review of patients who underwent lateral opening DFO for recurrent patellar instability in the setting of valgus leg alignment at a single academic institution between January 2016 to December 2021 was performed. Patients without a minimum 24-month postoperative follow-up were excluded.
