Lemborexant-induced interstitial lung disease: A case report.

We report the first case of drug-induced interstitial lung disease attributed to lemborexant. A 66-year-old man reported to our hospital with the acute onset of cough and breathlessness with ground-glass opacity on radiological examination. Symptoms were identified after taking lemborexant for 2 consecutive days.

Efficacy of antithrombin administration for patients with sepsis: A systematic review, meta-analysis, and meta-regression.

Aims: There have been inconsistent reports regarding the effect of antithrombin on sepsis; furthermore, there are limited reports on how dosage affects therapeutic efficacy. Thus, we aimed to perform a systematic review and meta-analysis of the use of antithrombin for sepsis and a meta-regression analysis of antithrombin dosage.

Methods: We included randomized controlled trials (RCTs) and observational studies of adult patients with sepsis who received antithrombin.

Calibration-free structured-light-based 3D scanning system in laparoscope for robotic surgery.

Accurate 3D shape measurement is crucial for surgical support and alignment in robotic surgery systems. Stereo cameras in laparoscopes offer a potential solution; however, their accuracy in stereo image matching diminishes when the target image has few textures. Although stereo matching with deep learning has gained significant attention, supervised learning requires a large dataset of images with depth annotations, which are scarce for laparoscopes.

Use of endoscopic hand-suturing to treat refractory bleeding from a gastric ulcer in a patient with a left ventricular assist device.

We herein describe a 49-year-old man with severe heart failure due to fulminant myocarditis who underwent left ventricular assist device implantation and received clopidogrel and warfarin as antithrombotic agents. The patient developed anemia secondary to chronic bleeding gastric hyperplastic polyps, necessitating endoscopic mucosal resection. Despite attempts to manage post-endoscopic mucosal resection bleeding from a gastric ulcer by endoscopic hemostasis using hemostatic forceps, local hemostatic agents, and polyglycolic acid sheets, the bleeding persisted.

Tele-proctoring for minimally invasive surgery across Japan: An initial step toward a new approach to improving the disparity of surgical care and supporting surgical education.

Aim: The aim of this study was to verify the clinical feasibility of tele-proctoring using our ultra-low latency communication system with shared internet access.

Methods: Connections between two multiple remote locations at various distances were established through the TELEPRO® tele-proctoring system. The server records the latency between the two locations for tele-proctoring using the annotations.

Immune checkpoint status and oncogenic mutation profiling of rectal cancer after neoadjuvant chemotherapy (KSCC1301-A2).

Aim: Immune checkpoint inhibitors (ICIs) are less effective in mismatch repair (MMR)-proficient (pMMR) colorectal cancers (CRCs) than in MMR-deficient CRCs. Here, we investigated changes in the tumor microenvironment after neoadjuvant chemotherapy (NAC) without radiotherapy in locally advanced rectal cancer (LARC) and the potential of ICIs as therapeutic agents for pMMR CRCs.

Methods: This was an ad hoc analysis of a KSCC1301 randomized phase II trial in which patients with untreated resectable LARC were randomly assigned to receive S-1 and oxaliplatin or folinic acid, 5-fluorouracil, and oxaliplatin as NAC.

MicroRNA-20a in extracellular vesicles derived from duodenal fluid is a possible biomarker for pancreatic ductal adenocarcinoma.

Background: Pancreatic ductal adenocarcinoma (PDAC) has a high mortality rate owing to its late diagnosis and aggression. In addition, there are relatively few minimally invasive screening methods for the early detection of PDAC, making the identification of biomarkers for this disease a critical priority. Recent studies have reported that microRNAs in extracellular vesicles (EV-miRs) from bodily fluids can be useful for the diagnosis of PDACs.

electrochemical regeneration of active 1,4-NADH for enzymatic lactic acid formation concerted functions on Pt-modified TiO/Ti.

Nicotinamide adenine dinucleotide (NAD) and its reduced form (NADH) are key cofactors serving as essential hydrogen acceptors and donors to facilitate energy and material conversions under mild conditions. We demonstrate direct electrochemical conversion to achieve highly efficient regeneration of enzymatically active 1,4-NADH using a Pt-modified TiO catalyst grown directly on a Ti mesh electrode (Pt-TOT). Spectral analyses revealed that defects formed by the inclusion of Pt species in the lattice of TiO play a critical role in the regeneration process.

Evaluation of the AB Score for Prediction of Survival in Patients With Heart Failure in a Nationwide Cohort in Japan.

Background: Although a tool for sharing patient prognosis among all medical staff is desirable in heart failure (HF) cases, only a few simple HF prognostic scores are available. We previously presented the AB score, a simple user-friendly HF risk score, and validated it in a small single-center cohort. In the present study, we validated it in a larger nationwide cohort.

Preliminary assessment of genetic variation in the Japanese endemic freshwater crab, , based on mitochondrial DNA sequences.

, a freshwater crab species endemic to Japan, has the largest distribution range amongst the 19 known species in the country. Due to its low dispersal capability and restricted habitat to freshwater, it serves as an excellent model for understanding gene flow between geographically isolated populations. In this study, we analysed the genetic relationships of 26 populations collected from different locations in the Japanese archipelago using two mitochondrial DNA regions - cytochrome oxidase subunit I ( and cytochrome b ().

No-wash fluorogenic labeling of proteins for reversible photoswitching in live cells.

Photoswitchable fluorescent molecules (PSFMs) are positioned as valuable tools for biomolecule localization tracking and super-resolution imaging technologies due to their unique ability to reversibly control fluorescence intensity upon light irradiation. Despite the high demand for PSFMs that are suitable for live-cell imaging, no general method has been reported that enables reversible fluorescence control on proteins of interest in living cells. Herein, we have established a platform to realize reversible fluorescence switching in living cells by adapting a protein labeling system.

Development of predictive score for postoperative dysphagia after emergency abdominal surgery in patients of advanced age.

Aim: Postoperative dysphagia after emergency abdominal surgery (EAS) in patients of advanced age has become problematic, and appropriate dysphagia management is needed. This study was performed to identify predictive factors of dysphagia after EAS and to explore the usefulness of swallowing screening tools (SSTs).

Methods: This retrospective study included 267 patients of advanced age who underwent EAS from 2012 to 2022.

Higher Cholesterol Absorption Marker at Baseline Predicts Fewer Cardiovascular Events in Elderly Patients Receiving Hypercholesterolemia Treatment: The KEEP Study.

Background: Higher cholesterol absorption has been reported to be related to a higher incidence of cardiovascular events (CVEs). The KEEP (Kyushu Elderly Ezetimibe Phytosterol) study, a substudy of the EWTOPIA 75 (Ezetimibe Lipid-Lowering Trial on Prevention of Atherosclerotic Cardiovascular Disease in 75 or Older) study, investigated the relationships of cholesterol absorption and synthesis markers with CVEs in older old individuals with hypercholesterolemia, particularly in relation to ezetimibe treatment.

Methods And Results: Eligible patients were those aged ≥75 years who had low-density lipoprotein cholesterol ≥140 mg/dL, no history of coronary artery disease, and no recent use of lipid-lowering drugs.

Pharmacoepidemiology and Clinical Correlates of Lithium Treatment for Bipolar Disorder in Asia.

Background: As clinical practices with lithium salts for patients diagnosed with bipolar disorder (BD) are poorly documented in Asia, we studied the prevalence and clinical correlates of lithium use there to support international comparisons.

Methods: We conducted a cross-sectional study of use and dosing of lithium salts for BD patients across 13 Asian sites and evaluated bivariate relationships of lithium treatment with clinical correlates followed by multivariate logistic regression modeling.

Results: In a total of 2139 BD participants (52.

Medication adherence and associated factors in newly diagnosed hypertensive patients in Japan: the LIFE study.

Hypertension is the leading cardiovascular risk factor worldwide. However, in Japan, only 30% of patients have their blood pressure controlled under 140/90 mmHg, and nonadherence to antihypertensives is thought to be a reason for the poor control of hypertension. We therefore sought to assess the adherence to hypertension treatment and to evaluate factors influencing patients' adherence in a large, representative sample of the Japanese population.

CD14 down-modulation as a real-time biomarker in Kawasaki disease.

Objectives: The objectives of this study were to investigate the pathophysiology of Kawasaki disease (KD) from immunological and oxidative stress perspectives, and to identify real-time biomarkers linked to innate immunity and oxidative stress in KD.

Methods: We prospectively enrolled 85 patients with KD and 135 patients with diverse conditions including immune, infectious and non-infectious diseases for this investigation. Flow cytometry was used to analyse the surface expression of CD14, CD38 and CD62L on monocytes, along with a quantitative assessment of CD14 down-modulation.

Association of gut microbiota with portal vein pressure in patients with liver cirrhosis undergoing living donor liver transplantation.

Background And Aim: Many recent studies have shown a relationship between various systemic diseases and the gut microbiota (GM), with the gut-liver axis receiving particular attention. In contrast, no report has comprehensively shown the effects of GM on the pathophysiology of patients undergoing living donor liver transplantation (LDLT).

Method: We enrolled 16 recipients who underwent LDLT for liver cirrhosis, and 17 donors constituted the reference group.

TRPV4-mediated Ca deregulation causes mitochondrial dysfunction via the AKT/α-synuclein pathway in dopaminergic neurons.

Mutations in the gene encoding the transient receptor potential vanilloid member 4 (TRPV4), a Ca permeable nonselective cation channel, cause TRPV4-related disorders. TRPV4 is widely expressed in the brain; however, the pathogenesis underlying TRPV4-mediated Ca deregulation in neurodevelopment remains unresolved and an effective therapeutic strategy remains to be established. These issues were addressed by isolating mutant dental pulp stem cells from a tooth donated by a child diagnosed with metatropic dysplasia with neurodevelopmental comorbidities caused by a gain-of-function TRPV4 mutation, c.
