It has been suggested that non-fasting triglyceride (TG) concentrations may be useful in predicting various diseases. However, current epidemiological evidence focuses mainly on the effects of fasting TG concentrations. The aim of this study was to investigate the effect of fasting and non-fasting TG levels on new-onset hyperuricemia (HUA) in the general Japanese population.

Xerostomia induced by antidepressants such as imipramine has long been thought to be due to their anticholinergic effects. However, even antidepressants with low anticholinergic effects may have a high incidence of xerostomia. In salivary glands, norepinephrine activates alpha-adrenergic receptors in blood vessels and beta-adrenergic receptors in acinar cells, respectively, causing a decrease in the blood flow and an increase in the protein secretion, resulting in the secretion of viscous saliva with low water content and high protein content.

Japanese guidelines recommend angiotensin II receptor blockers (ARBs) and angiotensin-converting enzyme inhibitors (ACEIs) as first-line therapy in hypertensive patients with chronic kidney disease (CKD) and proteinuria, but calcium channel blockers in patients with stage G4-5 CKD aged ≥75 years; however, the implementation of these guidelines in clinical practice is unclear. We investigated the actual use of these agents in this patient population. We conducted a cross-sectional study using the DeSC database, which includes anonymous information from various health insurance systems in Japan.

Objectives: The hemostatic mechanism of endoscopic detachable snare ligation (EDSL) for colonic diverticular hemorrhage (CDH) is similar to that of endoscopic band ligation, which is effective and safe. However, because reports on EDSL are scarce, we conducted a two-center cohort study to evaluate its effectiveness.

Methods: This study analyzed 283 patients with CDH treated with EDSL at two Japanese hospitals between July 2015 and November 2021.

Introduction: Breakfast-skipping habits are associated with adverse health outcomes including coronary heart disease, metabolic syndrome, and diabetes mellitus. However, it remains uncertain whether skipping breakfast affects chronic kidney disease (CKD) risk. This study aimed to examine the association between skipping breakfast and progression of CKD.

Article Synopsis
  • * The study created a new F-DES, [TMA]F·3.5[1,3-DMU], which has a high fluoride concentration and an electrochemical window of 3.1 V, significantly better than other F-DESs like [TMA]F·3.5[EG] which only had 1.9 V.
  • * This new solvent also showed much higher ionic conductivity—two orders of magnitude greater than another variant—due to the unique hydrogen bonding of its components, making it a promising option for electrochemical fluorination applications. *

Background: Lipoprotein glomerulopathy (LPG) is a apolipoprotein E (ApoE)-related glomerular disease and has been associated with type III hyperlipidemia. Without appropriate treatment, chronic kidney disease (CKD) caused by LPG progresses, and approximately half of the patients develop end-stage kidney disease within 1-27 years of disease onset. However, few studies have highlighted the clinical course of cardiovascular diseases (CVDs) in patients with LPG.

Tissue damage elicits cell fate switching through a process called metaplasia, but how the starting cell fate is silenced and the new cell fate is activated has not been investigated in animals. In cell culture, pioneer transcription factors mediate "reprogramming" by opening new chromatin sites for expression that can attract transcription factors from the starting cell's enhancers. Here we report that SOX4 is sufficient to initiate hepatobiliary metaplasia in the adult mouse liver, closely mimicking metaplasia initiated by toxic damage to the liver.

In this study, we aimed to separately evaluate the relationship between waist circumference and the incidence of hyperuricemia in men and women in the general Japanese population. We performed a population-based longitudinal study using data from the annual health examination of residents of Iki City, Japan. A total of 5567 participants without hyperuricemia at baseline were included in the analysis.

Article Synopsis
  • A nationwide surveillance in Japan studied the antimicrobial susceptibility of bacteria in acute uncomplicated cystitis, focusing on E. coli, K. pneumoniae, and S. saprophyticus, between April 2020 and September 2021.
  • The study isolated 823 bacterial strains from urine samples of 848 patients, with a majority being E. coli (92.9%), and determined susceptibility to 18 antibacterial agents.
  • Results showed a concerning increase in fluoroquinolone-resistant E. coli and extended-spectrum β-lactamase (ESBL)-producing E. coli, especially in postmenopausal women, highlighting the need for clinicians to adapt their antibiotic choices due to rising resistance rates.

Background: There are limited data on the impact of intracardiac echocardiography (ICE)-guided transcatheter aortic valve replacement (TAVR) on the new permanent pacemaker implantation (PPMI) rate.

Objectives: This study investigated the feasibility and outcome of transjugular ICE (TJ-ICE) -guided TAVR, by visualizing the relationship between the membranous septum (MS) and the transcatheter aortic valve (TAV).

Methods: Among patients with severe aortic stenosis who underwent TAVR between February 2017 and June 2020, this study enrolled a total of 163 patients with TJ-ICE-guided TAVR.

Purpose: This study aimed to investigate the safety and efficacy of lenvatinib in real-world settings, including patients excluded from the REFLECT trial, a phase III trial that compared lenvatinib with sorafenib.

Patients And Methods: This multicenter, nonrandomized, open-label prospective study was conducted at 10 medical facilities in Japan (jRCTs031190017). Eligible patients had advanced hepatocellular carcinoma (HCC) and were suitable for lenvatinib therapy.

Many molecular targeted agents, including biologics, have emerged for inflammatory bowel diseases (IBD), but their high prices have prevented their widespread use. This study aimed to reveal the changes in patient characteristics and the therapeutic strategies of IBD before and after the implementation of biologics in Japan, where the unique health insurance system allows patients with IBD and physicians to select drugs with minimum patient expenses. The analysis was performed using a prospective cohort, including IBD expert and nonexpert hospitals in Japan.

Klebsiella pneumoniae (Kpn) is one of the most common gram-negative bacilli causing lung, urinary tract, and biliary tract infections. However, as a distinct entity from classic Kpn, hypervirulent Kpn causing liver abscess, endophthalmitis, and lung abscess with poor prognoses has been reported mainly in East and Southeast Asia since the mid-1980s. Although the definition of hypervirulent Kpn is unclear, the hypermucoviscosity of Kpn is considered an important feature of hypervirulence.

Introduction: Non-fasting triglyceride (TG) concentrations are useful for predicting various diseases, but most epidemiological studies investigated the association between fasting TG concentrations and chronic kidney disease (CKD). This study aimed to examine the association between casual (fasting or non-fasting) serum TG concentrations and new-onset CKD in the general Japanese population.

Methods: We conducted a population-based, retrospective cohort study using annual health checkup data of residents of Iki City, Nagasaki Prefecture, Japan.

This practical guide has been developed to ensure safe and effective sedation performed in adult patients outside of the operating room, for instance in intensive care units and dental treatment rooms and in the field of palliative care. Sedation levels are classified based on level of consciousness, airway reflex, spontaneous ventilation, and cardiovascular function. Deep sedation induces loss of consciousness and protective reflexes, and can cause respiratory depression and pulmonary aspiration.

Given that the practices and institutions of knowledge production commonly referred to as 'science' are believed to have 'Western' origins, their apparent proliferation entails negotiations and power dynamics that shape both science and diplomacy in specific locales. This paper investigates a facet of this co-production of science and diplomacy in the emergence of knowledge infrastructure in Japan during the Allied Occupation. It focuses on the 1947 delegation from the United States National Academy of Sciences to Japan and its role in creating the Science Council of Japan (SCJ).
