This study aimed to investigate the release of metallic ions from cobalt-chromium (Co-Cr) alloys fabricated by additive manufacturing (AM) for comparison with dental casting. Co-Cr alloys were fabricated via AM using selective laser melting (SLM) and electron beam melting (EBM) in powder-bed fusion. Polished and mechanically ground specimens were prepared.

Outcomes of bile duct cannulation using a novel contrast-enhanced catheter: A single-center, retrospective cohort study.

Background: Endoscopic retrograde cholangiopancreatography is a challenging procedure involving bile duct cannulation. Despite the development of several cannulation devices, none have effectively facilitated the procedure.

Aim: To evaluate the efficacy of a recently developed catheter for bile duct cannulation.

Muscarinic receptor agonists and positive allosteric modulators in animal models of psychosis: protocol for a systematic review and meta-analysis.

Background: Muscarinic receptor agonism and positive allosteric modulation is a promising mechanism of action for treating psychosis, not present in most D2R-blocking antipsychotics. Xanomeline, an M1/M4-preferring agonist, has shown efficacy in late-stage clinical trials, with more compounds being investigated. Therefore, we aim to synthesize evidence on the preclinical efficacy of muscarinic receptor agonists and positive allosteric modulators in animal models of psychosis to provide unique insights and evidence-based information to guide drug development.

Relationship Between One-Leg Standing and Foot Sole Sensation Following Short-Term Immobilization of a Unilateral Lower Extremity.

Background: Several studies have suggested that approximately 10 hours of inactivity can reduce motor performance. Specifically, restricted lower limb movement may impair postural stability, subsequently increasing the incidence of falls. However, the relationship between postural sway and its related factors remains unclear.

Inadvertent insertion of dialysis catheter into subclavian artery treated with a covered stent: A case report.

Background: When inserting central venous catheters, inadvertent injury of major vessels is a rare yet critical complication. Direct surgery is sometimes overly invasive. This report describes a subclavian artery injury caused by inadvertent cannulation of a dialysis catheter, successfully treated with a covered stent.

α-Lipoic acid increases phagocytosis of some lactic acid bacteria via modulation of CD36 expression.

Phagocytosis by immunocompetent cells is a key role in the biological defense mechanism and is the starting point of the reaction that leads from innate to acquired immunity. Several studies have demonstrated that some lactic acid bacteria strains activate the innate and acquired immune systems of the host. However, further investigation of the mechanism and improvement of usefulness is needed because the effect differs depending on the type and strain of lactic acid bacteria.

Cooperation of Cysteine, Ascorbic Acid, Pyridoxine, and α-Lipoic Acid in Antioxidant Effects on Human Keratinocytes and 3D Human Skin Models.

Combinations of cysteine, ascorbic acid, and pyridoxine are frequently used in oral formulations. Although there have been many reports on the efficacy of each of these ingredients, little information is known about their combined effects on skin cells. The purpose of this study was to evaluate the combined effects of cysteine, ascorbic acid, and pyridoxine, as well as the effect of adding α-lipoic acid, on skin cells.

Refractory phenotype of -sensitized asthma with bronchiectasis and allergic bronchopulmonary aspergillosis.

Background: Sensitization to mucus plugs, and bacterial colonization may coexist and relate to a refractory phenotype during follow-up in asthma with bronchiectasis and allergic bronchopulmonary aspergillosis (ABPA).

Objective: This study aimed to clarify the features of -sensitized refractory asthma with bronchiectasis and determine the refractory phenotype in this population and ABPA.

Methods: This study included cases of the oldest available -specific IgE data and chest computed tomography images from a nationwide survey of refractory asthma with bronchiectasis.

Imaging-tracked progression of primary leptomeningeal gliomatosis: A case report.

Background: Primary leptomeningeal gliomatosis (PLG) is a rare neoplasm characterized by the diffuse spread of glial tumor cells throughout the leptomeninges without any evidence of a primary tumor source in the brain or spinal cord parenchyma. Here, we present a case of PLG potentially linked to prior interventional radiotherapy.

Case Description: The patient was a 75-year-old woman with a history of interventional radiology for a left internal carotid cavernous sinus fistula 13 years before presentation.

Efficacy and tolerability of blonanserin in schizophrenia: A systematic review and meta-analysis of randomized controlled trials.

Background: Blonanserin is approved for treating schizophrenia in Japan, South Korea, India, and China. We aimed to synthesize the efficacy and tolerability of blonanserin compared to other antipsychotics.

Methods: A systematic review and pairwise meta-analysis were conducted using the Cochrane Schizophrenia Group's study-based trial register until January 24, 2024.

A phase 1 dose escalation of pritumumab in patients with refractory or recurrent gliomas or brain metastases.

Background: This phase 1 (NCT04396717) open-label, multicenter study, evaluated Pritumumab, a IgG1 monoclonal antibody, in patients with gliomas and brain metastases. The primary objective was to evaluate the safety and/or tolerability and to identify a recommended phase 2 dose (RP2D) of Pritumumab.

Methods: Adult patients with recurrent gliomas or brain metastases were enrolled in the dose cohort that was open at the time of their consent.

Structural basis for hepatitis B virus restriction by a viral receptor homologue.

Macaque restricts hepatitis B virus (HBV) infection because its receptor homologue, NTCP (mNTCP), cannot bind preS1 on viral surface. To reveal how mNTCP loses the viral receptor function, we here solve the cryo-electron microscopy structure of mNTCP. Superposing on the human NTCP (hNTCP)-preS1 complex structure shows that Arg158 of mNTCP causes steric clash to prevent preS1 from embedding onto the bile acid tunnel of NTCP.

Membrane structure-responsive lipid scrambling by TMEM63B to control plasma membrane lipid distribution.

Phospholipids are asymmetrically distributed in the plasma membrane (PM), with phosphatidylcholine and sphingomyelin abundant in the outer leaflet. However, the mechanisms by which their distribution is regulated remain unclear. Here, we show that transmembrane protein 63B (TMEM63B) functions as a membrane structure-responsive lipid scramblase localized at the PM and lysosomes, activating bidirectional lipid translocation upon changes in membrane curvature and thickness.

Propofol-alone sedative efficacy in observational biliopancreatic endoscopic ultrasound.

Objectives: Appropriate sedative and analgesic selection is essential to reduce patient discomfort and body movement to safely conduct endoscopic ultrasonography (EUS). However, few cases have examined sedation with propofol in EUS, and few studies the need for combined analgesia. In this study, we retrospectively evaluated the usefulness and safety of propofol without analgesics for sedation in biliopancreatic observational EUS.

Platelet and white blood cell counts correlate with leptin and body mass index in Japanese adolescents.

Obesity is associated with mild chronic inflammation, frequently observed along with increased platelet and white blood cell (WBC) levels in adults. We aimed to clarify the relationship between peripheral blood cell count, body mass index standard deviation score (BMI-SDS), and adipocytokine levels in obese adolescents. Participants included 31 patients with obesity (age: 13.

Comparison of disease and risk classifications of AML before and after incorporation of NGS analysis of bone marrow samples.

Mutation profiling by next-generation sequencing (NGS) has facilitated understanding of the molecular pathogenesis of acute myeloid leukemia (AML), and has been incorporated into the new disease classification (International Consensus Classification; ICC) and risk classification (European LeukemiaNet [ELN] 2022; ELN2022). We compared disease subtypes between the previous disease classification (4th edition of the WHO classification; WHO-4) and the ICC in 91 patients with AML diagnosed at our institution. We also compared disease risk classifications using the previous risk classification (ELN2017) and the ELN2022.

Effectiveness of pharmacological treatments for severe agitation in real-world emergency settings: protocol of individual-participant-data network meta-analysis.

Background: Severe psychomotor agitation and aggression often require immediate pharmacological intervention, but clear evidence-based recommendations for choosing among the multiple options are lacking. To address this gap, we plan a systematic review and individual-participant-data network meta-analysis to investigate their comparative effectiveness in real-world emergency settings with increased precision.

Methods: We will include randomized controlled trials investigating intramuscular or intravenous pharmacological interventions, as monotherapy or in combination, in adults with severe psychomotor agitation irrespective of the underlying diagnosis and requiring rapid tranquilization in general or psychiatric emergency settings.

Trace amine-associated receptor 1 (TAAR1) agonism for psychosis: a living systematic review and meta-analysis of human and non-human data.

Background: Trace amine-associated receptor 1 (TAAR1) agonism shows promise for treating psychosis, prompting us to synthesise data from human and non-human studies.

Methods: We co-produced a living systematic review of controlled studies examining TAAR1 agonists in individuals (with or without psychosis/schizophrenia) and relevant animal models. Two independent reviewers identified studies in multiple electronic databases (until 17.

Patient-authored medical record II: A not-knowing approach to psychiatric nursing.

A patient-authored medical record (PAMR) is a narrative-based prescription that is written by a psychiatric patient with help from a nurse. It is a tool specifically designed and developed for psychiatric nursing. We have reported its notable therapeutic effects for Japanese patients and found that the patients had accurate views of how to improve their illness.
