Prevalence of Non-alcoholic Fatty Liver Disease Detected by Computed Tomography in the General Population Compared with Ultrasonography.

Objective To assess the prevalence and clinical correlates of non-alcoholic fatty liver disease (NAFLD) identified by computed tomography (CT) in the general population compared with ultrasonography (US). Methods Four hundred and fifty-eight subjects who received health checkups at Meijo Hospital in 2021 and underwent CT within a year of US in the past decade were analyzed. The mean age was 52.

Tracheoarterial fistula in a patient with amyotrophic lateral sclerosis successfully managed by overinflation of the tracheostomy tube cuff alone: a case report.

Background: Tracheoarterial fistula is the most devastating complication after tracheostomy, and its mortality, without definitive treatment, approaches 100%. In general, the combination of bedside emergency management, that is, overinflation of the tracheostomy tube cuff, and definitive treatment such as surgical or endovascular intervention is necessary to prevent the poor outcome. Patients with neuromuscular diseases such as amyotrophic lateral sclerosis are susceptible to tracheoarterial fistula because of long-term mechanical ventilation and muscle weakness.

Prevalence of nonalcoholic fatty liver disease and its association with age in patients with type 2 diabetes mellitus.

Background: Type 2 diabetes mellitus (T2DM) is a risk factor for nonalcoholic fatty liver disease (NAFLD).

Aim: To determine the prevalence and clinical correlates of NAFLD in a large cohort of patients with T2DM.

Methods: Four hundred thirty-seven participants with T2DM who consulted at Meijo Hospital from April 2019 to September 2020 and underwent computed tomography (CT) were assessed.

The case of a liver-transplant recipient with severe acute respiratory syndrome coronavirus 2 infection who had a favorable outcome.

The outbreak of coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was identified in 2019; thereafter, the COVID-19 outbreak became a health emergency of international concern. The impact of COVID-19 on liver-transplant recipients is unclear. Thus, it is currently unknown whether liver-transplant recipients are at a higher risk of developing complications related to COVID-19.

Association between intensive care unit delirium and delusional memory after critical care in mechanically ventilated patients.

Aim: To determine the relationship between the delirium of patients with mechanical ventilation during intensive care unit (ICU) stay and delusional memory after ICU discharge.

Design: Prospective cohort study.

Methods: Delirium in adult patients who received mechanical ventilation for more than 24 hr was assessed twice daily using the Confusion Assessment Method for the ICU.

Effects of Manual Rib Cage Compressions on Mucus Clearance in Mechanically Ventilated Pigs.

Background: Manual rib cage compression is a chest physiotherapy technique routinely used in clinical practice. However, scientific evidence remains scarce on the effects of manual rib cage compression on airway clearance and oxygenation in mechanically ventilated patients.

Methods: Anesthetized pigs were intubated via the trachea and mechanically ventilated.

Influence of prolonged translaryngeal intubation on airway complications: a retrospective comparative analysis.

Purpose: Tracheostomy is usually suggested to facilitate airway management of intensive care unit (ICU) patients requiring prolonged translaryngeal intubation (PTLI). While it is not uncommon for physicians to hesitate and delay to perform it for more than 2 weeks, clinically recognizable airway adverse effects following PTLI are rarely discussed. Therefore, we compared retrospectively the PTLI group with control to assess them in adult patients.

Improving the neurological prognosis following OHCA using real-time evaluation of cerebral tissue oxygenation.

Background: The neurological prognosis is poor for patients suffering from out-of-hospital cardiac arrest (OHCA), in the absence of bystander cardio pulmonary resuscitation (CPR), and showing asystole as the initial waveform. However, such patients have the potential of resuming social activity if cerebral tissue oxygen saturation can be preserved.

Case Presentation: We recently encountered a 60-year-old man who had suffered an OHCA in the absence of bystander CPR, and who successfully resumed complete social activity despite initial asystole and requiring at least 75min of chest compressions before return of spontaneous circulation (ROSC).

Descriptive epidemiology of traumatic spinal injury in Japan.

Background: Spine injury epidemiology in Japan has not been studied since the 1990s when its incidence was 39.4-40.2 per million and the major cause of injury was motor vehicle crashes.

Cerebral Tissue Oxygenation Index Using Near-infrared Spectroscopy during Extracorporeal Cardio-pulmonary Resuscitation Predicted Good Neurological Recovery in a Patient with Acute Severe Anemia.

We herein report the clinical course of a patient who had a good neurological outcome despite severe anemia, high serum lactate levels, and a long period of time from cardiac arrest (CA) to extracorporeal cardio-pulmonary resuscitation (ECPR) establishment. During the period of resuscitation, the tissue oxygenation index (TOI) values were measured continuously by a near-infrared spectroscopy monitoring device and were kept within the normal range. The TOI seems to reflect cerebral perfusion and the balance between the oxygen supply and demand in the brain during ECPR, thereby predicting the neurological outcome.

Landiolol hydrochloride ameliorates acute lung injury in a rat model of early sepsis through the suppression of elevated levels of pulmonary endothelin-1.

Among the dysfunctions and pathologies associated with sepsis, the underlying molecular mechanisms of sepsis-induced acute lung injury (ALI) are poorly understood. Endothelin (ET)-1, a potent vasoconstrictor and pro-inflammatory peptide, is known to be involved in the pathogenesis of ALI in a rat model of sepsis. Here, we investigated whether landiolol hydrochloride, an ultra-short-acting β-blocker, plays a crucial role in ameliorating and attenuating LPS-induced ALI through modulation of the ET-1 system.

Renal contrast microangiography with synchrotron radiation: a novel method for visualizing structures within nephrons in vivo.

Background No non-invasive method of observing renal microcirculation in vivo has been established as yet. Although angiography is considered to be ideally suited for the purpose, conventional X-rays cannot be used to image structures smaller than 100 µm. Purpose To develop a method for visualizing the renal arterioles, glomeruli, and proximal tubules of rats in vivo making use of synchrotron radiation.

Severity of delirium in the ICU is associated with short term cognitive impairment. A prospective cohort study.

Objectives: To examine the hypothesis that severity of delirium in the intensive care unit (ICU) is positively associated with cognitive impairment at the time of hospital discharge.

Design: A prospective cohort study.

Setting: Adult medical and surgical ICU of a tertiary-care teaching hospital in Japan in ICU patients who were enrolled and admitted for more than 48hours.

Efficacy of concomitant use of dexmedetomidine and propofol in tetanus.

Tetanus is an infectious disease caused by Clostridium tetani, which manifests systemic convulsion and autonomic instability associated with high case fatality. Despite proper medical intervention, management of those symptoms is often difficult. We report a case of 67-year-old man with tetanus in which a concomitant use of dexmedetomidine, an adrenaline α-2 receptor agonist, and propofol, a GABA(A) receptor binding agent, was successful in the management of systemic convulsion and autonomic instability without necessitating conventional anticonvulsant, neuromuscular blocking agents, or tracheostomy.

Hyperinflation deteriorates arterial oxygenation and lung injury in a rabbit model of ARDS with repeated open endotracheal suctioning.

Background: Hyperinflation (HI) is performed following open endotracheal suctioning (OES), whose goals include: to stimulate a cough, recover oxygenation and improve compliance. However, it may also induce unintended consequences, including: lung stress and strain, failure to maintain high distending pressure, and subsequently cycling recruitment and derecruitment. Here, our aim was to investigate the effects of hyperinflation after repeated OES on sequential alteration of arterial oxygenation and lung injury profile using a saline lavage-induced surfactant depleted ARDS rabbit model.

Higher circulatory level of endothelin-1 in hypertensive subjects screened through a cross-sectional study of rural Bangladeshi women.

Endothelin-1 (ET-1) is a potential marker of the endothelial dysfunction, which has been shown to be elevated in hypertensive subjects. No previous study has investigated the circulatory level of ET-1 and hypertension in a South Asian country. The present study assessed the circulating levels of ET-1 in subjects with or without hypertension and further examined the association of ET-1 with clinical and metabolic parameters.

Effects of selective endothelin (ET)-A receptor antagonist versus dual ET-A/B receptor antagonist on hearts of streptozotocin-treated diabetic rats.

Aims: The aim was to study the differences in the effectiveness of two types of endothelin (ET) receptor antagonists (selective ET-A or dual ET-A/B antagonists) on the hearts of streptozotocin (STZ)-induced diabetic rats (type I diabetes) at functional and biochemical/molecular levels.

Main Methods: Citrate saline (vehicle) or STZ was injected into rats. The ET-A/B dual receptor antagonist (SB209670, 1mg/kg/day) and the ET-A receptor antagonist (TA-0201, 1mg/kg/day) were then administered to these rats.

Severe Pulmonary Suppuration with Infection-Induced Systemic Inflammatory Response Syndrome following Tongue Cancer Surgery in a Patient Undergoing Tocilizumab Therapy for Rheumatoid Arthritis.

A 65-year-old woman with rheumatoid arthritis treated by tocilizumab (TCZ) presented with tongue squamous cell carcinoma. While surgery was performed without any complications the aspiration pneumonia rapidly worsened by postoperative day 2 and severe pulmonary suppuration in the right lung field with infection-induced systemic inflammatory response syndrome (SIRS) was diagnosed. Antibiotic and respirator treatment improved her condition.

Potential amelioration of upregulated renal HIF-1alpha-endothelin-1 system by landiolol hydrochloride in a rat model of endotoxemia.

Aims: Endothelin (ET)-1 is the best known potent vasoconstrictor and has been implicated in pathogenesis of sepsis-associated acute kidney injury (AKI) in human or lipopolysaccharide (LPS)-induced AKI in animal models. We have previously shown that ET-1 is highly up-regulated in renal tissues and in plasma after LPS administration. Here, we investigated whether landiolol hydrochloride, an ultra-short-acting beta-blocker, can play an important role in ameliorating levels of LPS-induced up-regulation of renal HIF-1α-ET-1 system and inflammatory cytokines in a rat model of endotoxemia.

Fish oil constituent eicosapentaenoic acid inhibits endothelin-induced cardiomyocyte hypertrophy via PPAR-α.

Aims: A growing body of evidence shows the cardiovascular benefits of fish oil ingredients, including eicosapentaenoic acid (EPA), in humans and experimental animals. However, the effects of EPA on endothelin (ET)-1-induced cardiomyocyte hypertrophy and the involved signaling cascade are largely unknown. A previous study has demonstrated that peroxisomal proliferator-activated receptor (PPAR)-α ligand (fenofibrate) prevents ET-1-induced cardiomyocyte hypertrophy.

Assessment of circulatory and pulmonary endothelin-1 levels in a lavage-induced surfactant-depleted lung injury rabbit model with repeated open endotracheal suctioning and hyperinflation.

Aims: Endothelin-1 (ET-1) is a mediator of various physiological and pathological processes, including vascular inflammation, cell proliferation and vasoconstriction. Attenuation of ET action using ET-1 antagonists reduces pulmonary vascular leakage and inflammation in several models of lung injuries and experimental acute respiratory distress syndrome (ARDS). Based on these earlier reports, the current study investigates the patterns of ET-1 levels in circulation and pulmonary tissues in an experimental model of lavage-induced surfactant-depleted lung injury.
