Recent Findings: Using low-dose whole spine CT (CT syndesmophyte score [CTSS]) improved diagnostic accuracy for evaluating spinal structural progression than previous method (modified Stoke Ankylosing Spondylitis Spinal Score [mSASSS]) in axSpA. The novel definition of positive finding of sacroiliac joint (SIJ) and spine magnetic resonance imaging (MRI) enabled to diagnose axSpA earlier than plain radiography.

The role of placenta Hofbauer cells during pregnancy and pregnancy complications.

Placental Hofbauer cells (HBCs) are specialized macrophages present in the human placenta that play a crucial role in maintaining a healthy pregnancy. These cells are derived from the fetal mesoderm and are responsible for various functions, including immune regulation, angiogenesis, and nutrient transport. In normal pregnancies, HBCs primarily exhibit an M2 or immunomodulatory phenotype, which helps maintain a tolerant and anti-inflammatory environment at the maternal-fetal interface.

GRIM-19-mediated induction of mitochondrial STAT3 alleviates systemic sclerosis by inhibiting fibrosis and Th2/Th17 cells.

The gene associated with the retinoid-IFN-induced mortality-19 (GRIM-19) protein is a regulator of a cell death regulatory protein that inhibits STAT3, which is a critical transcription factor for interleukin (IL)-17-producing T (Th17) cells and a key integrator of extracellular matrix accumulation in systemic sclerosis (SSc). This protein is also a component of mitochondrial complex I, where it directly binds to STAT3 and recruits STAT3 to the mitochondria via the mitochondrial importer Tom20. In this study, the role of GRIM19 and its relationship with STAT3 in SSc development was investigated using a murine model of SSc.

Glioma subtype prediction based on radiomics of tumor and peritumoral edema under automatic segmentation.

Comprehensive and non-invasive preoperative molecular diagnosis is important for prognostic and therapy decision-making in adult-type diffuse gliomas. We employed a deep learning method for automatic segmentation of brain gliomas directly from conventional magnetic resonance imaging (MRI) scans of the tumor core and peritumoral edema regions based on available glioma MRI data provided in the BraTS2021. Three-dimensional volumes of interest were segmented from 424 cases of glioma imaging data retrospectively obtained from two medical centers using the segmentation method and radiomic features were extracted.

Middle ear cholesteatoma and facial nerve hypertrophy mimicking schwannoma in Charcot-Marie-Tooth disease: A case report.

Rationale: Charcot-Marie-Tooth (CMT) disease, a hereditary motor and sensory neuropathy, presents with progressive chronic sensory and distal motor polyneuropathy. While sensorineural hearing loss and vestibular impairment have been documented in CMT patients, concurrent middle ear cholesteatoma and persistent direction-changing positional nystagmus have not.

Patient Concerns: This study details a 22-year-old man with CMT1 exhibiting these symptoms.

Small heterodimer partner-interacting leucine zipper protein suppresses pain and cartilage destruction in an osteoarthritis model by modulating the AMPK/STAT3 signaling pathway.

Objective: Osteoarthritis (OA) is a degenerative joint disease caused by the breakdown of joint cartilage and adjacent bone. Joint injury, being overweight, differences in leg length, high levels of joint stress, abnormal joint or limb development, and inherited factors have been implicated in the etiology of OA. In addition to physical damage to the joint, a role for inflammatory processes has been identified as well.

Understanding Metabolic Pathway Rewiring by Oncogenic Gamma Herpesvirus.

Gamma herpesviruses, including Epstein-Barr virus (EBV) and Kaposi's sarcoma-associated herpesvirus (KSHV), are key contributors to the development of various cancers through their ability to manipulate host cellular pathways. This review explores the intricate ways these viruses rewire host metabolic pathways to sustain viral persistence and promote tumorigenesis. We look into how EBV and KSHV induce glycolytic reprogramming, alter mitochondrial function, and remodel nucleotide and amino acid metabolism, highlighting the crucial role of lipid metabolism in these oncogenic processes.

Multisystem diseases in the abdomen and pelvis: imaging manifestations and diagnostic roles of cross-sectional imaging.

Systemic diseases, such as IgG4-related disease, sarcoidosis, and amyloidosis, usually involve multiple systems or organs simultaneously or sequentially. The gastrointestinal tract, hepatobiliary system, and genitourinary tract are commonly involved in many multisystem diseases and can also be the first sites with disease involvement. Cross-sectional imaging, such as CT and MR, plays an important role in the diagnosis and management of multisystem diseases by aiding in the evaluation of multiorgan involvement.
