Investigating the Unexpected Effect of Bulkheads in a Dementia Model of Mice Through Molecular Analysis of the Hippocampus.

Aim: This study aimed to evaluate the impact of long-term exposure to physical barriers used as preventive measures during the coronavirus disease 2019 (COVID-19) pandemic on cognitive function and behavior in an apolipoprotein E (ApoE) mouse dementia model.

Methods: ApoE mice were divided into co-housed, partitioned by a transparent bulkhead (partitioned), and isolated groups. To assess anxiety, cognitive recognition, and spatial learning, behavioral tests, including the open-field test, novel object recognition test, and Morris water maze test, were conducted at three and six months after the start of the 33-week rearing period.

Effects of 6-month administration of tofogliflozin on cardiac function in elderly patients with heart failure with preserved ejection fraction: A retrospective study of a patient cohort.

Patients with type 2 diabetes mellitus are frequently hospitalized for heart failure. The ratio of early diastolic mitral inflow velocity to early diastolic mitral annulus velocity (E/e'), measured by echocardiography, is a simple and convenient indicator of diastolic dysfunction. Various large clinical trials have reported that sodium glucose transporter-2 inhibitor therapy reduced cardiovascular events and hospitalizations in heart failure patients.

Procalcitonin, brain natriuretic peptide and albumin as markers to predict prognosis in hospitalized older Japanese patients with a risk of infection.

Aim: Whether serum concentration of procalcitonin (PCT), brain natriuretic peptide (BNP) and albumin (Alb) have an association with the outcome of hospitalized older patients is unclear. We investigated clinical outcomes and any predictive factors in hospitalized Japanese older patients with a risk of infection.

Methods: In the retrospective study, 820 Japanese patients were followed up for 30 days or until death.

Expert consensus document on automated diagnosis of the electrocardiogram: The task force on automated diagnosis of the electrocardiogram in Japan part 3: Inappropriate internal processing in the automatic diagnosis of electrocardiograms and its problems.

Computer diagnosis of electrocardiograms is widely used to provide useful information in clinical practice and medical checkups. However, it is common for users to be confused by the inappropriate diagnosis. We illustrate some examples of inappropriate automatic diagnoses and discuss the actual situation of inappropriate automatic processing and its problems.

Increasing averaging beats improves the test accuracy on Holter-based late potentials in patients with myocardial infarction.

Background: The prevalence of Holter-based late potentials (H-LPs) in cases of fatal cardiac events has increased. Although the noise level of H-LP is higher than that of conventional real-time late potential (LP) recording, a procedure to reduce the noise severity in H-LP by increasing the averaging beats has not been investigated.

Methods: We enrolled 104 patients with post-myocardial infarction (MI) and 86 control participants.

Diurnal Variation in and Optimal Time to Measure Holter-Based Late Potentials to Predict Lethal Arrhythmia after Myocardial Infarction.

: Holter-based late potentials (LPs) are useful for predicting lethal arrhythmias in organic cardiac diseases. Although Holter-based LPs exhibit diurnal variation, no studies have evaluated the optimal timing of LP measurement over 24 h for predicting lethal arrhythmia that leads to sudden cardiac death. Thus, this study aimed to validate the most effective timing for Holter-based LP testing and to explore factors influencing the diurnal variability in LP parameters.

Prognostic value of B-type natriuretic peptide for nursing- and healthcare-associated pneumonia and aspiration pneumonia in comparison with procalcitonin and A-DROP score: a prospective cohort study.

Background: Pneumonia in elderly patients who require nursing care is becoming more and more common among the aging populations of developed countries, and treatment is an important topic worldwide. A simpler prognostic indicator would be expected to improve the treatment of pneumonia. This single-center, prospective cohort study aimed to compare the usefulness of B-type natriuretic peptide (BNP), procalcitonin (PCT), and the A-DROP score, which have been reported to correlate with pneumonia prognoses, such as aspiration pneumonia (AP).

Age-related reference intervals for ambulatory electrocardiographic parameters in healthy individuals.

Background: The advent of novel monitoring technologies has dramatically increased the use of ambulatory electrocardiography (AECG) devices. However, few studies have conducted detailed large-scale investigations on the incidence of arrhythmias over 24 h, especially ectopy, in healthy individuals over a wide age range.

Objectives: This study aimed to investigate the incidence of arrhythmias detected using AECG and associated factors, in healthy individuals, over a wide age range.

The Impact of Tofogliflozin on Physiological and Hormonal Function, Serum Electrolytes, and Cardiac Diastolic Function in Elderly Japanese Patients with Type 2 Diabetes Mellitus.

The sodium glucose transporter 2 (SGLT2) inhibitor tofogliflozin is a glucose-lowering drug that causes the excretion of surplus glucose by inhibiting SGLT2. Because of tofogliflozin's osmotic diuresis mechanism, patients' serum electrolytes, body fluid levels, and cardiac function must be monitored. We retrospectively analyzed the cases of 64 elderly Japanese patients with type 2 diabetes mellitus (T2DM) who received tofogliflozin for 3 months.

A new predictive tool consolidating CURB-65 with procalcitonin and albumin to assess short-term mortality in hospitalized elderly patients with infectious disease: A retrospective study of a patient cohort.

Background: Hospitalized elderly patients are often at risk of life-threatening infectious diseases such as pneumonia and urinary tract infection, thus diagnostic tools for bacterial infections are demanded. We developed a new predictive tool consolidating modified CURB-65, procalcitonin (PCT) and albumin (Alb).

Method: This is a retrospective study.

Expert consensus document on automated diagnosis of the electrocardiogram: The task force on automated diagnosis of the electrocardiogram in Japan: Part 2: Current status of inappropriate automated diagnosis is widely used electrocardiographs in Japan.

It is important to objectively grasp the current status of automated electrocardiogram (ECG) diagnosis. This report aimed to analyze and evaluate ECG records that our members have encountered as an inappropriate diagnosis in real-world clinical practices.

Effects of tofogliflozin on adrenocorticotropic hormone, renin and aldosterone, and cortisol levels in elderly patients with diabetes mellitus: A retrospective study of a patient cohort.

Adrenocorticotropic hormone (ACTH) and cortisol reportedly play a role in glycemic control in patients with type 2 diabetes mellitus (T2DM); however, the underlying mechanism remains controversial. We retrospectively investigated the effect of tofogliflozin on serum ACTH and cortisol levels in elderly patients with T2DM.Patients received 20 mg tofogliflozin daily for 3 months.

Diffuse large B cell lymphoma originating from the maxillary sinus with skin metastases: A case report and review of literature.

Background: Diffuse large B-cell lymphoma (DLBCL) is the most common type of malignant lymphoma (ML), accounting for 30%-40% of cases of non-Hodgkin's lymphoma (NHL) in adults. Primary paranasal sinus lymphoma is a rare presentation of extranodal NHL that accounts for only 0.17% of all lymphomas.

Disseminated Spinal Epidural Abscess in an Immunocompetent Individual: A Case Report and Review of the Literature.

Spinal epidural abscess (SEA) is an uncommon pyogenic infection, localized between the dura mater and vertebral periosteum, leading to significant morbidity and mortality. SEA development is connected with medical comorbidities and risk factors facilitating bacterial dissemination; multiple factors are believed to play a role, including aging, increased alcohol abuse, use of intravenous drugs, a greater prevalence of medical comorbidities, and increased rates of spinal surgery that furthers iatrogenic spinal infection. Here, we have reported the first known case of disseminated SEA in an immunocompetent individual.

Expert consensus document on automated diagnosis of the electrocardiogram: The task force on automated diagnosis of the electrocardiogram in Japan. Part 1: Nomenclature for diagnosis and abnormal findings.

As these terms should accurately represent the abnormal findings and conditions as much as possible, we propose to unify these terms into terminologies that are not confusing and easy to understand for everyone.

Successful Treatment with Percutaneous Balloon Kyphoplasty for Syndrome of Inappropriate Secretion of Antidiuretic Hormone Associated with Vertebral Compression Fracture: A Case Report.

BACKGROUND The etiology of syndrome of inappropriate antidiuretic hormone secretion (SIADH) is highly variable. With little evidence, much of the guidance and recommendations available for management are based on clinical judgement. Although percutaneous balloon kyphoplasty can effectively relieve the severe pain associated with osteoporotic vertebral compression fractures that do not respond to conventional treatments, the effect of balloon kyphoplasty on SIADH associated with vertebral compression fracture remains unknown.

Combination effects of a fatty diet and exercise on the depressive state and cardioprotection in apolipoprotein E knockout mice with a change in expression.

Objective: Regulator of calcineurin 1 (RCAN1) controls plasticity of the nervous system and depressive conditions by regulating brain-derived neurotropic factor (BDNF) and plays a crucial role in neural and cardiac pathways. The apolipoprotein E gene () is a robust risk factor for progression of Alzheimer's disease. A fatty diet is considered detrimental for metabolic disorders, such as obesity and cardiovascular diseases.

Intracranial malignant solitary fibrous tumor metastasized to the chest wall: A case report and review of literature.

Background: Solitary fibrous tumor (SFT) is a rare fibroblastic mesenchymal neoplasm that affects spindle cell soft tissues with broad-spectrum biological behavior; it is predominantly benign, and rarely metastasizes. SFT occurs mainly in the tissue structure of the serosa in the pleura and the thorax, and can be found throughout the body, though extra-thoracic localization, including the cephalic region, is un-common. We reported the first case of intracranial malignant SFT metastasized to the chest wall.

Abdominal compartment syndrome due to extremely elongated sigmoid colon and rectum plus fecal impaction caused by disuse syndrome and diabetic neuropathy: a case report and review of the literature.

Background: Abdominal compartment syndrome (ACS) is defined as a sustained raised level of intra-abdominal pressure more than 20 mmHg with or without abdominal perfusion pressure less than 60 mmHg and the development of new end-organ failure. Abdominal surgery, major trauma, volvulus, ileus, distended abdomen, fecal impaction, acute pancreatitis, liver dysfunction, sepsis, shock, obesity, and age have all been reported as risk factors. Herein, we report the severest known case of ACS due to extremely elongated sigmoid colon and rectum plus fecal impaction caused by disuse syndrome and diabetic neuropathy, together with a brief review of the literature.

Combined evaluation of ambulatory-based late potentials and nonsustained ventricular tachycardia to predict arrhythmic events in patients with previous myocardial infarction: A Japanese noninvasive electrocardiographic risk stratification of sudden cardiac death (JANIES) substudy.

Background: Noninvasive electrocardiographic (ECG) markers are promising arrhythmic risk stratification tools for identifying sudden cardiac death. However, little is known about the usefulness of noninvasive ECG markers derived from ambulatory ECGs (AECG) in patients with previous myocardial infarction (pMI). We aimed to determine whether the ECG markers derived from AECG can predict serious cardiac events in patients with pMI.
