Risk of artery dissection during systemic exposure to vascular endothelial growth factor pathway inhibitors.

Whether or not vascular endothelial growth factor pathway inhibitors (VPIs) increase the risk of artery dissection is still unknown. This study aimed to quantitatively evaluate the possibility of artery dissection as a class effect of VPIs using nationwide real-world data. This cohort study was conducted based on the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB), which spans nearly the entire Japanese population of over 100 million individuals.

Prescription trend and lactic acidosis in patients prescribed metformin before and after the revision of package insert for allowing metformin administration to patients with moderately decreased kidney function based on real-world data from MID-NET in Japan.

Introduction: This study was conducted to understand the impact of package insert (PI) revision in Japan on 18 June 2019 to allow metformin use for patients with moderately decreased kidney function (30 ≤ estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m).

Methods: A new user cohort design was employed to examine the prescription trend and the occurrence of lactic acidosis in patients prescribed metformin before and after PI revision using the Medical Information Database Network (MID-NET).

Real-world prescription of anti-COVID-19 drugs in hospitalized patients with COVID-19 in Japan.

Objective: Prescription trends and patterns of anti-COVID-19 drugs in hospitalized patients were examined based on real world data to understand the use of anti-COVID-19 drugs in clinical practice in Japan.

Design: The longitudinal and cross-sectional study was conducted utilizing data from January 1, 2019 to December 31, 2021 of the MID-NET® medical information database, which stored the electronic medical records, administrative claim data, and diagnosis procedure combination data of patients in Japan.

Participants: Hospitalized patients with a COVID-19-related diagnosis who received at least one anti-COVID-19 drug between April 1, 2020 and December 31, 2021.

Induction of antitoxic antibody and preventive effect against porcine edema disease by the pentameric Stx2eB subunit vaccine.

Porcine edema disease (ED) is an enterotoxaemia that frequently occurs in 4-12 week-old piglets and results in high mortality. ED is caused by Shiga toxin 2e (Stx2e), produced by host-adapted Shiga toxin-producing Escherichia coli (STEC) strains. We constructed a recombinant protein in which the B subunit of Stx2e (Stx2eB) was linked to Cartilage Oligomeric Matrix Protein (COMP)'s pentameric domain to enhance antigenicity to induce neutralizing antibodies against Stx2e.

Prevalence of hypertensive diseases and treated hypertensive patients in Japan: A nationwide administrative claims database study.

We investigated the prevalence of hypertensive patients and treated hypertensive patients using a Japanese nationwide administrative claims database. We analyzed national database data from 2014, including all claims data, provided by the Ministry of Health, Labour and Welfare of Japan. Hypertensive diseases were identified using Japanese standardized disease codes.

Prediction of Lifetime Risk of Cardiovascular Disease Deaths Stratified by Sex in the Japanese Population.

Background Lifetime risk is an informative estimate for driving lifestyle and behavioral changes especially for young adults. The impact of composite risk factors for cardiovascular disease on lifetime risk stratified by sex has not been investigated in the Japanese population, which has a much lower mortality of coronary heart disease compared with the Western population. We aimed to estimate lifetime risk of death from cardiovascular disease attributable to traditional risk factors.

Association between adherence to warfarin and thrombotic events in patients with antiphospholipid syndrome in Japan: A claims-based retrospective cohort study.

Purpose: We aimed to evaluate adherence and persistence to warfarin therapy among patients with antiphospholipid syndrome (APS) and investigate the association between adherence and thrombotic events in those patients.

Methods: We conducted a retrospective cohort study using the Japan Medical Data Center claims database from 2005 to 2018. Patients with APS receiving warfarin treatment were included in this study.

Protocol and Rationale for the Russian-Japanese "Tackle Obesity and Metabolic Syndrome Outcome by Diet, Activities and Checking Body Weight Intervention" (RJ-TOMODACHI) Randomized Controlled Trial.

The prevalence of obesity in Russia has increased sharply since the mid-1990s. Interestingly, the prevalence of obesity in Japan is lower than in many Western countries. Japan has implemented different types of weight control programs using a smart device to monitor patients remotely.

Alcohol drinking and brain morphometry in apparently healthy community-dwelling Japanese men.

The clinical implications of alcohol consumption have been extensively examined; however, its effects on brain structures in apparently healthy community-dwellers remain unclear. Therefore, we investigated the relationship between alcohol consumption and brain gray matter volume (GMV) in community-dwelling Japanese men using voxel-based morphometry (VBM). We recruited cognitively intact Japanese men, aged 40-79 years, from a population-based cohort in Shiga, Japan.

A Combination of Blood Pressure and Total Cholesterol Increases the Lifetime Risk of Coronary Heart Disease Mortality: EPOCH-JAPAN.

Aim: Lifetime risk (LTR) indicates the absolute risk of disease during the remainder of an individual's lifetime. We aimed to assess the LTRs for coronary heart disease (CHD) mortality associated with blood pressure (BP) and total cholesterol levels in an Asian population using a meta-analysis of individual participant data because no previous studies have assessed this risk.

Methods: We analyzed data from 105,432 Japanese participants in 13 cohorts.

Waist Circumference and Domain-Specific Cognitive Function Among Non-Demented Japanese Older Adults Stratified by Sex: Results from the Takashima Cognition Study.

Background: While being obese in mid-life is associated with an increased risk of dementia and cognitive decline in late-life, being obese in late-life is shown to be associated with a lower risk of these outcomes in some studies. This phenomenon is known as the "obesity paradox", but the underlying reasons and potential sex difference have not been well understood.

Objective: To investigate the association between cognition and waist circumference (WC), an alternative measure of body fat which can be measured easier than body mass index (BMI), among older adults in each generation of late-life for men and women separately.

Industry Perspective of Pediatric Drug Development in the United States: Involvement of the European Union Countries.

Background: Efforts to promote the development of pediatric pharmacotherapy include regulatory frameworks and close collaboration between the US Food and Drug Administration and the European Medicines Agency. We characterized the current status of pediatric clinical trials conducted in the United States by the pharmaceutical industry, focusing on the involvement of the European Union member countries, to clarify the industry perspective.

Methods: Data on US pediatric clinical trials were obtained from ClinicalTrials.

Isolation and expression of five-amino-acid-deleted variant of feline hepatocyte growth factor (HGF) cDNA.

Hepatocyte growth factor (HGF) is a pleiotropic cytokine that stimulates a wide array of cellular targets, including hepatocytes and other epithelial cells, melanocytes, endothelial and hematopoietic cells. We have cloned a different form of cDNA, with a deletion of 15 base pairs predicted to result in the loss of 5 amino acids from the first kringle domain. To investigate the biological activity, original and deleted variant of feline HGF cDNAs were transiently expressed in COS-7 cells.
