Association between the Rostral Anterior Cingulate Cortex and Anterior Insula in the Salience Network on Response to Antidepressants in Major Depressive Disorder as Revealed by Isolated Effective Coherence.

Introduction: Functional connectivity is attracting increasing attention for understanding the pathophysiology of depression and predicting the therapeutic efficacy of antidepressants. In this study, we evaluated effective connectivity using isolated effective coherence (iCoh), an effective functional connectivity analysis method developed from low-resolution brain electromagnetic tomography (LORETA) and estimated its practical usefulness for predicting the reaction to antidepressants in theta and alpha band iCoh values.

Methods: We enrolled 25 participants from a depression treatment randomized study (the GUNDAM study) in which electroencephalography was performed before treatment.

Effect of Novel Stratified Lipid Risk by "LDL-Window" and Flow-Mediated Dilation on the Prognosis of Coronary Artery Disease Using the FMD-J Study A Data.

Background: Elevated levels of triglyceride (TG) and non-high-density lipoprotein cholesterol (non-HDL-C) are regarded as a residual lipid risk in low-density lipoprotein cholesterol (LDL-C)-lowering therapy. This study investigated the association between lipid risk stratified by TG and non-HDL-C and the prognosis of patients with coronary artery disease (CAD), and the association between stratified lipid risk and flow-mediated dilatation (FMD) index.

Methods and results: The 624 CAD patients enrolled in flow-mediated dilation (FMD)-J study A were divided into 4 groups: low-risk group (n=413) with TG <150 mg/dL and non-HDL-C <170 mg/dL; hyper-TG group (n=180) with TG ≥150 mg/dL and non-HDL-C <170 mg/dL; hyper-non-HDL group (n=12) with TG <150 mg/dL and non-HDL-C ≥170 mg/dL; and high-risk group (n=19) with TG ≥150 mg/dL and non-HDL-C ≥170 mg/dL.

Association between Acid-Suppressive Drugs and Clinical Outcomes in Patients with Nonvalvular Atrial Fibrillation.

Purpose: Acid-suppressive drugs (ASDs) are often prescribed for patients with nonvalvular atrial fibrillation (NVAF) taking oral anticoagulants (OACs). However, the risk-benefit balance of ASDs prescription for patients with NVAF taking OACs is still unclear. This study aimed to assess the association between ASDs and clinical outcomes in patients taking OACs for NVAF.

Clinical Benefit of Switching from Low-Dose to High-Dose Empagliflozin in Patients with Type 2 Diabetes.

Introduction: Sodium-dependent glucose cotransporter 2 (SGLT2) inhibitors ameliorate blood glucose levels in patients with type 2 diabetes mellitus (T2DM) by inhibiting the reabsorption of glucose from the kidneys, thus increasing urinary glucose excretion. Most SGLT2 inhibitors have been reported to exert dose-dependent effects. However, little is known about the benefits of increasing the dose of SGLT2 inhibitors in clinical use.

U-shaped association between abnormal serum uric acid levels and COVID-19 severity: reports from the Japan COVID-19 Task Force.

Objectives: This study aimed to identify the relationship between abnormal serum uric acid levels or a history of hyperuricemia and COVID-19 severity in the Japanese population.

Methods: We included 1523 patients enrolled in the Japan COVID-19 Task Force cohort between February 2020 and May 2021. We compared the clinical characteristics, including co-morbidities, laboratory findings, and outcomes, particularly invasive mechanical ventilation (IMV), among patients with and without abnormal uric acid levels or a history of hyperuricemia.

Methods: Data from 1,033 consecutive patients with intramedullary tumors, treated between 2009 and 2020, were collected from 58 centers. Patients with spinal lipomas or myxopapillary ependymomas were excluded.

Embodiment of supernumerary robotic limbs in virtual reality.

The supernumerary robotic limb system expands the motor function of human users by adding extra artificially designed limbs. It is important for us to embody the system as if it is a part of one's own body and to maintain cognitive transparency in which the cognitive load is suppressed. Embodiment studies have been conducted with an expansion of bodily functions through a "substitution" and "extension".

Proposal of a novel protocol using estimated cardiac index fractional dose to improve aortic contrast enhancement for early-phase dynamic CT.

Maximum aortic computed tomography value (CTV) is difficult to control because of variations in cardiac function and patient physique. Therefore, to improve early-phase aortic enhancement on dynamic computed tomography (CT), we developed an estimated cardiac index fractional dose (eciFD). The eciFD protocol is a novel and original protocol for administering fractional dose (FD), representing the amount of iodine per unit body weight per injection duration, based on cardiac index (cardiac output divided by body surface area) as estimated by age in early-phase dynamic CT.

[A Case Report of a Patient with Metastatic Adrenocortical Carcinoma who Received the Combination Etoposide, Doxorubicin, Cisplatin, and Mitotane Therapy and Achieved Remission].

A 40-year-old Japanese female was referred to our institution with a high serum lactate dehydrogenase level. Computed tomography (CT) showed a large right adrenal tumor, 14 cm in size without distant metastases. The patient was clinically diagnosed with T2N0M0 adrenocortical carcinoma and underwent right adrenalectomy.

Validation of a Patient-Derived Xenograft Model for Cervical Cancer Based on Genomic and Phenotypic Characterization.

Patient-derived xenograft (PDX) models are useful tools for preclinical drug evaluation, biomarker identification, and personalized medicine strategies, and can be developed by the heterotopic or orthotopic grafting of surgically resected tumors into immunodeficient mice. We report the PDX models of cervical cancer and demonstrate the similarities among original and different generations of PDX tumors. Fresh tumor tissues collected from 22 patients with primary cervical cancer were engrafted subcutaneously into NOD.

Association between the duration of antibiotic prophylaxis and surgical site infection after orthognathic surgery in Japan.

Th17-Dependent Nasal Hyperresponsiveness Is Mitigated by Steroid Treatment.

Th17 cells are implicated in allergic inflammatory diseases, including allergic rhinitis (AR), though the effect of steroids on Th17 cell-dependent nasal responses is unclear. Herein, we investigated a nasal inflammation model elicited by allergen provocation in mice infused with Th17 cells and its responsiveness against steroid treatment. We transferred BALB/c mice with Th17 cells, which were differentiated in vitro and showed a specific reaction to ovalbumin (OVA).

Quantification of high and low sEMG spectral components during sustained isometric contraction.

Superficial Electromyography (sEMG) spectrum contains aggregated information from several underlying physiological processes. Due to technological limitations, the isolation of these processes is challenging, and therefore, the interpretation of changes in muscle activity frequency is still controversial. Recent studies showed that the spectrum of sEMG signals recorded from isotonic and short-term isometric contractions can be decomposed into independent components whose spectral features recall those of motor unit action potentials.

Extracellular vesicles expressing CEACAM proteins in the urine of bladder cancer patients.

Early detection and long-term monitoring are important for urothelial carcinoma of the bladder (UCB). Urine cytology and existing markers have insufficient diagnostic performance. Here, we examined medium-sized extracellular vesicles (EVs) in urine to identify specific markers for UCB and evaluated their usefulness as diagnostic material.

A single immunization with cellular vaccine confers dual protection against SARS-CoV-2 and cancer.

The efficacy of current coronavirus disease 2019 (COVID-19) vaccines has been demonstrated; however, emerging evidence suggests insufficient protection in certain immunocompromised cancer patients. We previously developed a cell-based anti-cancer vaccine platform involving artificial adjuvant vector cells (aAVCs) capable of inducing a strong adaptive response by enhancing the innate immunity. aAVCs are target antigen-transfected allogenic cells that simultaneously express the natural killer T-cell ligand-CD1d complex on their surface.

Propionic Acid, Induced in Gut by an Inulin Diet, Suppresses Inflammation and Ameliorates Liver Ischemia and Reperfusion Injury in Mice.

Liver ischemia and reperfusion injury (IRI) is one of the obstacles in liver surgery such as liver resection and transplantation. In this study, we investigated the preventive effect on mouse liver IRI by feeding mice with inulin, which is a heterogeneous blend of indigestible fructose polymer. Mice were fed either a control ordinary diet (CD) or an inulin diet (ID) containing 5% inulin in the CD, for 14 days before the ischemia and reperfusion (IR) maneuver.
