Rare dual MYH9-ROS1 fusion variants in a patient with lung adenocarcinoma: A case report.

Medicine (Baltimore)

January 2025

Department of Respiratory and Critical Care Medicine, Zhongshan City People's Hospital, Zhongshan, Guangdong Province, China.

Rationale: ROS proto-oncogene 1 (ROS1) fusion is a rare but important driver mutation in non-small cell lung cancer, which usually shows significant sensitivity to small molecule tyrosine kinase inhibitors. With the widespread application of next-generation sequencing (NGS), more fusions and co-mutations of ROS1 have been discovered. Non-muscle myosin heavy chain 9 (MYH9) is a rare fusion partner of ROS1 gene as reported.

Small Bowel Leiomyoma Mimics Neuroendocrine Tumor on 68Ga-DOTATATE PET/CT.

Clin Nucl Med

January 2025

Department of Nuclear Medicine, Royal Free London NHS Foundation Trust, London, United Kingdom.

A 57-year-old man with a 3-month history of lower abdominal pain and rectal bleeding with black stools underwent urgent abdominal CT, which revealed an ovoid hyperdense lesion in the ileum in the right iliac fossa. The prime differential was a midgut neuroendocrine tumor. Thus, the patient was referred for a 68Ga-DOTATATE PET/CT scan, which demonstrated intense activity in this lesion with no evidence of somatostatin receptor expression elsewhere.

Case: A 60-year-old right-hand-dominant woman experienced progressive enlargement of a mass over the index distal interphalangeal (DIP) joint over 5 years, leading to joint destruction and swan neck deformity. Radiography showed arthritis, erosion, and calcific deposition. Surgical intervention included mass excision, synovectomy, and DIP joint arthrodesis.

Bauxite mining has been caused severe changes in the natural ecosystems of the Amazon, but the restoration of these areas is mandatory by federal law in Brazil. The recolonization of fauna is crucial to establishing the ecological functions of recovering forests, and the small nonflying mammals can stand out in this process. Assessing taxonomic and functional diversity parameters, we demonstrated that in the early stages of forest recovery post-bauxite mining, between 6 and 11 years, it is possible to restore approximately 45% of the richness of small non-flying mammal species from the original habitats, that in this case were altered Primary Forests.

We present a model of opinion formation where an individual's opinion is influenced by interactions with a group of agents. The model introduces a novel bias mechanism that favors one opinion, a feature not previously explored. In the absence of bias, the system reduces to a mean field voter model.
