Novel classification system and high-risk categories of pediatric acute myeloid leukemia.

The prognosis of pediatric acute myeloid leukemia (AML) remains poor compared with pediatric acute lymphoblastic leukemia (ALL); accurate diagnosis and treatment strategies based on the genomic background are strongly needed. Recent advances in sequencing technologies have identified novel pediatric AML subtypes, including BCL11B structural variants and UBTF tandem duplications (UBTF-TD), associated with poor prognosis. In contrast, these novel subtypes do not fit into the diagnostic systems for AML of the 5th edition WHO classification or International Consensus Classifications (ICC) released in 2022.

Impact of Janus kinase inhibitors and methotrexate on interstitial lung disease in rheumatoid arthritis patients.

Objectives: Little is known about how various treatments impact the progression of interstitial lung disease (ILD) in rheumatoid arthritis (RA) patients. Here, we compared ILD progression in RA patients treated with Janus kinase inhibitors (JAKi) or biological disease-modifying anti-rheumatic drugs (bDMARDs). experiments were also performed to evaluate the potential effects of the drugs on epithelial-mesenchymal transition (EMT), a key event in pulmonary fibrosis.

CT scoring system for differentiating of sinonasal inverted papilloma and squamous cell carcinoma arising from inverted papilloma.

Objective: To distinguish squamous cell carcinoma in inverted papilloma (IP-SCC) from IP, the utility of CT scoring system was investigated.

Methods: We extracted cases histopathologically diagnosed with IP and IP-SCC of the sinonasal cavity from June 2004 to May 2021. Preoperative unenhanced CT images were used to evaluate the presence or absence of bone destruction and erosion: Score 1 = positive for bone destruction and/or erosion; Score 0 = negative for bone destruction and erosion.

Factors Related to the Growth of Oral Bacteria After Surgery: An Observational Study of 54 Patients Undergoing Oncologic or Cardiac Surgery.

Introduction Postoperative complications, such as surgical site infection and postoperative pneumonia, may be caused by oral bacteria. This study aimed to clarify the factors related to the bacterial count in the saliva of postoperative patients so as to standardize oral management methods before and after surgery. Methods This prospective observational study enrolled 54 patients who underwent major oncologic or cardiac surgery.
