Alveolar capillary endothelial cell (EC) injury has a pivotal role in driving acute respiratory distress syndrome (ARDS) progression and maintaining endothelial homeostasis. A previous ex vivo study revealed that overexpression of homeobox B4 (HOXB4) in bone marrow mesenchymal stem cells (BMSCs) enhanced protection against lipopolysaccharide (LPS)-induced EC injury by activating the Wnt/β-catenin pathway. This in vivo study was performed to verify whether BMSCs overexpressing HOXB4 exert similar protective effects on LPS-induced acute lung injury (ALI) in an animal model. ⋯ HOXB4-overexpressing BMSCs optimized the protective effect against LPS-induced ALI by partially activating Wnt/β-catenin signaling.

Post-transplant diabetes mellitus (PTDM) is a well-known solid organ transplant complication, which can be related to immunosuppressants, particularly tacrolimus. We report an unusual presentation of PTDM with diabetic ketoacidosis (DKA). This is unique as PTDM typically resembles Type 2 DM, whereas DKA is associated with Type 1 DM and has rarely been reported as a complication of tacrolimus. ⋯ This unusual PTDM case may have resulted from both autoimmune and tacrolimus-induced beta cell destruction. Physicians should be aware of new onset LADA post-transplantation and tacrolimus toxicity leading to DKA, even in patients without traditional risk factors. Anti-GAD antibody screening in patients on tacrolimus who develop PTDM may identify patients less likely to recover beta cell function with immunosuppression augmentation which requires careful monitoring.

Circular RNAs (circRNAs) are involved in tumorigenesis and the progression of cancer through various pathways. However, the detailed regulatory mechanisms of circRNAs in cervical cancer are not fully understood. The present study was designed to explore the biological functions and potential mechanisms of circCLIP2 (has_circ_0001717) in cervical cancer. ⋯ The circCLIP2/miR-361-3p/STAT2 signalling could mediate the progression of cervical cancer. CircCLIP2 may become a novel target for the diagnosis and treatment of cervical cancer.

Review Case Reports
Perils of Reduced Dose Apixaban In Atrial Fibrillation/Flutter - A Case Report with a Brief Literature Review.
Patients with atrial fibrillation/atrial flutter (AF) are notoriously predisposed to thromboembolic events secondary to the development of thrombi within the left atrium of the heart. AF accompanied by a fairly decent CHA2DS2-VASc score is a known indication for full anticoagulation, frequently with direct oral anticoagulants (DOACs), such as apixaban. ⋯ However, with rising concern for bleeding complications, many physicians are found to have been reducing the dose of apixaban despite the patient not completely meeting the defined criteria. Our study particularly emphasizes the risk of significantly increased thromboembolic complications in the setting of sub-therapeutic anticoagulation, in patients with both appropriately and inappropriately reduced doses of apixaban.
