Methods: This observational study included Medicare fee-for-service beneficiaries aged 65 to 99 years treated with pVAD for CS from 2016 to 2020.

Serum Autotaxin Levels Predict Liver-Related Events in Patients With Primary Biliary Cholangitis: A Long-Term Multicenter Observational Study.

Introduction: A straightforward, reliable, and noninvasive method for predicting the development of liver-related events (LRE) in primary biliary cholangitis (PBC) has not been attained thus far. This study investigated whether serum autotaxin (ATX) could predict LRE in patients with PBC.

Methods: This retrospective multicenter investigation included 190 biopsy-proven untreated patients with PBC.

L-Carnitine: A New Therapeutic Option for the Prevention of Atrial Fibrillation in Non-Cardiac Surgery-A Single-Group Interventional Pilot Study.

L-carnitine is essential in lipid metabolism and reportedly has preventive effects for arrhythmia. Our objective was to examine the incidence of postoperative atrial fibrillation (POAF) and changes in serum biomarker levels following perioperative L-carnitine administration in patients with lung cancer. Thirteen patients undergoing a lobectomy with preoperative serum brain natriuretic peptide levels >24 pg/mL were perioperatively administered L-carnitine for 5 days (3 g/3×).

Impact of Dupilumab on Skin Surface Lipid-RNA Profile in Severe Asthmatic Patients.

The analysis of skin surface lipid-RNAs (SSL-RNAs) provides a non-invasive method for understanding the molecular pathology of atopic dermatitis (AD), but its relevance to asthma remains uncertain. Although dupilumab, a biologic drug approved for both asthma and AD, has shown efficacy in improving symptoms for both conditions, its impact on SSL-RNAs is unclear. This study aimed to investigate the impact of dupilumab treatment on SSL-RNA profiles in patients with severe asthma.

Scoring model for the diagnosis of colorectal perforation and its differentiation from gastroduodenal perforation.

Purpose: Distinguishing colorectal from gastroduodenal perforations is clinically important and challenging. We aimed to establish a scoring model based on objective findings (excluding computed tomography findings) for the diagnosis of colorectal perforation and its differentiation from gastroduodenal perforation.

Methods: Patients diagnosed with colorectal or gastroduodenal perforations between January 2014 and December 2021 were retrospectively studied.

Osteogenic effects and safety of human induced pluripotent stem cell-derived megakaryocytes and platelets produced on a clinical scale.

Introduction: Platelet-rich plasma obtained by centrifuging peripheral blood can promote osteogenesis owing to its abundant growth factors but has drawbacks, including rapid growth factor loss and inconsistent effects depending on donor factors. To overcome these issues, we were the first in the world to use freeze-dried human induced pluripotent stem cell-derived megakaryocytes and platelets (S-FD-iMPs) and found that they have osteogenesis-promoting effects. Since turbulence was found to activate platelet biogenesis and iPS cell-derived platelets can now be produced on a clinical scale by a device called VerMES, this study examined the osteogenesis-promoting effect and safety of clinical-scale FD-iMP (V-FD-iMPs) for future human clinical application.

Embolization of posterior fossa meningiomas supplied with meningohypophyseal trunk by using BCA and dual balloon protection.

Background And Purpose: Efficacy of tumor embolization for posterior fossa meningioma is controversial due to the lack of adequate embolization for dangerous feeders. Of these, a meningohypophyseal trunk (MHT) has high therapeutic value despite the high risks associated with embolization.

Materials And Methods: To analyze the utility of preoperative MHT embolization for posterior fossa meningiomas using BCA with dual balloon protection, a single center retrospective record review was performed on eight consecutive patients who underwent preoperative tumor embolization via the MHT for posterior fossa meningiomas between 2020 and 2024.

Active role of the immune system in metabolic dysfunction-associated steatotic liver disease.

Non-alcoholic fatty liver disease, recently renamed metabolic dysfunction-associated steatotic liver disease (MASLD), is a complex multifactorial disease that progresses from steatohepatitis (MASH) to liver cirrhosis and liver cancer. Recent research has revealed that crosstalk between innate immune cells and hepatic parenchymal and non-parenchymal cells is involved in the pathogenesis of liver disease in MASLD/MASH. Of particular importance, novel inflammatory mechanisms, including macrophage diversity, neutrophil NETosis, B-cell biology, auto-reactive T cells, unconventional T cells, and dendritic cell-T cell interactions, are considered key drivers for disease progression.

The Therapeutic Efficacy of Abatacept for Rheumatoid Arthritis-Associated Interstitial Lung Disease: Insights from a 12-Month Trial Using Semi-Quantitative Chest High-Resolution Computed Tomography Imaging.

Rheumatoid arthritis-associated interstitial lung disease (RA-ILD) is a major complication of rheumatoid arthritis (RA), but effective treatment remains an unmet need in its management. Our aim was to evaluate the therapeutic efficacy of abatacept for RA-ILD. This observational retrospective study included patients with RA-ILD treated with abatacept between 2012 and 2021.

Generation of human-pig chimeric renal organoids using iPSC technology.

Porcine organs and human induced pluripotent stem cell (iPSC)-derived organoids as alternative organs for human transplantation have garnered attention, but both face technical challenges. Interspecies chimeric organ production using human iPSCs shows promise in overcoming these challenges. Our group successfully generated chimeric renal organoids using human iPSC-derived nephron progenitor cells (NPCs) and fetal mouse kidneys.

Lithium-induced cognitive dysfunction assessed over 1-year hospitalisation: A case report.

Introduction: Lithium-induced neurotoxicity is almost always reversible but can cause irreversible neurological sequelae, namely the syndrome of irreversible lithium-effectuated neurotoxicity (SILENT). As there is no definitive treatment for SILENT, caution is required when administering lithium. Reports on the effect of lithium-effectuated neurotoxicity on cognitive function are limited.

Safety, pharmacokinetics, and pharmacodynamics of ART-648, a PDE4 inhibitor in healthy subjects: A randomized, placebo-controlled phase I study.

Phosphodiesterase 4 (PDE4) inhibitor is associated with a broad-spectrum anti-inflammatory mechanism. However, securing clinically efficacious doses with sufficient safety margins remains challenging due to class specific adverse events that are often unavoidable in the clinic. ART-648 is an orally available PDE4 inhibitor being developed for the treatment of inflammatory diseases.

Barley β-glucan consumption improves glucose tolerance by increasing intestinal succinate concentrations.

Barley is rich in β-glucan, which can alter gut microbiota and metabolome profiles, potentially affecting host metabolism. However, the microbiota and metabolites increased by barley β-glucan remain unclear. In this study, we focused on the gut-microbiota-derived metabolite succinate and investigated the microbiome and metabolome profiles altered by barley β-glucan intake.

Acute effects of empagliflozin on open-loop baroreflex function and urine output in streptozotocin-induced type 1 diabetic rats.

Although sympathetic suppression is considered one of the mechanisms for cardioprotection afforded by sodium-glucose cotransporter 2 (SGLT2) inhibitors, whether SGLT2 inhibition acutely modifies sympathetic arterial pressure (AP) regulation remains unclear. We examined the acute effect of an SGLT2 inhibitor, empagliflozin (10 mg/kg), on open-loop baroreflex static characteristics in streptozotocin (STZ)-induced type 1 diabetic and control (CNT) rats (n = 9 each). Empagliflozin significantly increased urine flow [CNT: 25.

Threonine Phosphorylation and the Yin and Yang of STAT1: Phosphorylation-Dependent Spectrum of STAT1 Functionality in Inflammatory Contexts.

Threonine phosphorylation promotes inflammatory functions of STAT1 while restricting its interferon (IFN) signaling in innate immune responses. However, it remains unclear whether the restriction of STAT1-mediated IFN signaling conferred by threonine phosphorylation is a ubiquitous mechanism or one that is context-dependent. To address this, we utilized pristane-induced lupus, a prototype IFN-driven systemic autoimmune disease model characterized by the production of high-titer autoantibodies against nucleic acid-associated antigens.
