Alternative Splicing at the Crossroad of Inflammatory Bowel Diseases and Colitis-Associated Colon Cancer.

The risk of developing colorectal cancer (CRC) is increased in ulcerative colitis patients compared to the general population. This increased risk results from the state of chronic inflammation, a well-known tumour-promoting condition. This review explores the pathologic and molecular characteristics of colitis-associated colon cancer (CAC), emphasizing the distinct features from sporadic CRC.

Hemosporidian infection in free-living Cathartes aura (Linnaeus, 1758) in the Amazon biome, Pará State, Brazil: Parasitological, molecular, hematological, and biochemical analyses.

Hemosporidians are intracellular pathogens that infect a range of endothermic and ectothermic hosts and are transmitted by dipteran vectors. These parasites are grouped into four families: Haemoproteidae, Plasmodiidae, Leucocytozoidae, and Garniidae, with the genera Haemoproteus, Plasmodium, and Leucocytozoon being the most common in birds. Therefore, the objectives of this study were to detect the infection frequency of hemosporidians and to perform hematological and biochemical analyses in free-living turkey vultures (Cathartes aura) in the Amazon biome, Brazil.

Iatrogenic intramural esophageal hematoma during EUS-B-FNA procedure.

Background: Esophageal ultrasound with bronchoscope fine needle aspiration (EUS-B-FNA) is a valuable tool for the diagnosis and staging of lung cancer, complementing endobronchial lung ultrasound (EBUS). While generally considered safe, there is a notable lack of comprehensive knowledge within the interventional pulmonology community regarding potential complications.

Case Presentation: We present a case involving a 66-year-old male with squamous cell lung carcinoma undergoing mediastinal staging.
