Background And Hypothesis: We aimed to evaluate the diagnostic validity of the International Classification of Diseases, 10th Revision (ICD-10) codes for hyponatremia and hypernatremia, using a database containing laboratory data. We also aimed to clarify whether corrections for blood glucose, triglyceride, and total protein may affect the prevalence and the diagnostic validity.
Methods: We retrospectively identified admissions with laboratory values using a Japanese hospital-based database.
Purpose Postoperative infections pose an important problem for patients with cardiac disease. Moreover, oral health status is associated with the risk of longer hospital stays. Therefore, the oral health status of patients was assessed before open-heart surgery.

Material And Methods: We retrospectively identified individuals with diabetes during routine health checkups performed in 2019 in Japan using a population-based claims database (JMDC, Tokyo, Japan). We assessed the risk of COVID-19 infection in 2020 in relation to HbA1c levels during routine checkups, stratified by the presence/absence of follow-up for diabetes care in 2019.
Introduction: Preventive programs, including screenings for cancer and diabetes, were disrupted globally due to the coronavirus disease 2019 (COVID-19) pandemic in 2020. We previously conducted a nationwide survey to investigate the initial impact of the pandemic on health check-ups; however, the impact in the second and third years of the pandemic has not yet been elucidated. Here, we conducted a follow-up survey targeting healthcare facilities to evaluate the impact of the pandemic until the end of 2022.

- Proteinuria, a condition where excess proteins are found in urine, is linked to a higher risk of kidney issues, heart disease, and cancer, prompting this study to explore its relationship with bone fractures.
- Researchers analyzed a large Japanese database to assess the connection between proteinuria and hip or vertebral fractures, using advanced statistical methods to account for factors like kidney health.
- The study found that individuals with trace or positive proteinuria had a significantly higher risk of fractures, suggesting that monitoring protein levels in urine could be crucial for predicting fracture risks.
Context: Previous studies failed to adjust for estimated glomerular filtration rate (eGFR) in evaluating the association between albuminuria and anemia development, and we aimed to investigate whether albuminuria independently affects anemia development.
Methods: We conducted a retrospective cohort study and retrospectively identified adults with diabetes from a Japanese nationwide clinical database (JMDC, Tokyo, Japan). To assess the modification effects of albuminuria on the association between eGFR and anemia development, we estimated prevalence of anemia, defined as hemoglobin < 13 g/dL in men and < 12 g/dL in women, using a modified Poisson regression and marginal standardization form of predictive margins, stratified by albuminuria severity after adjusting for eGFR.
Article Synopsis
- This study investigates the effectiveness of bowel preparation using polyethylene glycol lavage (PEL) in patients with suspected colonic diverticular bleeding (CDB) who underwent early colonoscopy within 24 hours.
- The analysis, which included data from 10 institutions, revealed that patients prepared with PEL had shorter hospital stays and higher rates of successful cecal intubation compared to those without PEL preparation.
- The findings suggest that PEL is beneficial for early colonoscopy in CDB cases, with no significant difference in adverse events or treatment outcomes between the two groups.
Introduction: Health check-ups have been disrupted worldwide by the COVID-19 pandemic, especially at its beginning. In Japan, undergoing annual check-ups is mandatory for full-time employees of all ages, while those other than full-time employees are entitled to undergo nonmandatory cancer screenings and specific health check-ups. To evaluate the impact of the COVID-19 pandemic on health check-ups, we conducted a nationwide questionnaire survey targeting healthcare facilities.
View Article and Find Full Text PDFAims: We aimed to explore the association between short-term exposure to temperature variability (TV), and cardiovascular hospitalization stratified by the presence of comorbid diabetes.
Methods: We collected data on nationwide hospitalization for cardiovascular diseases and daily weather conditions during 2011-2018 in Japan. TV was calculated as the standard deviation of daily minimum and maximum temperatures within 0-7 lag days.
Background: Scarce data on factors related to discharge disposition in patients hospitalized for acute heart failure (AHF) were available, and we sought to develop a parsimonious and simple predictive model for non-home discharge via machine learning.
Methods: This observational cohort study using a Japanese national database included 128,068 patients admitted from home for AHF between April 2014 and March 2018. The candidate predictors for non-home discharge were patient demographics, comorbidities, and treatment performed within 2 days after hospital admission.
To improve the success of mechanical thrombectomy, three-dimensional turbo spin-echo (3D-TSE) sequences on T2WI can be employed to estimate the vascular structure of the posterior circulation. In addition to the short imaging time of 3D-TSE T2WI (33 sec), it can visualize the outer diameter of the main cerebral artery, including the occluded vessels. However, to date, the efficacy of mechanical thrombectomy in the posterior circulation remains unclear, and safer and more efficient mechanical thrombectomy procedures are required.

We aimed to examine differences in bleeding complications between intravenous sedation and general anesthesia in pediatric patients.
Methods: Data of pediatric patients aged ≤ 15 years undergoing percutaneous kidney biopsy for kidney disease between July 2007 and March 2019 were retrieved from a national inpatient database in Japan.
Article Synopsis
- A study analyzed the relationship between modifiable risk factors (like obesity, hypertension, and diabetes) and cardiovascular disease (CVD) events among over 3 million participants, categorized by age groups.
- Results showed that the incidence of CVD events, including myocardial infarction and heart failure, increased with age, but the impact of these modifiable risk factors was stronger in younger individuals.
- Prevention strategies targeting these risk factors may be more beneficial if implemented during younger ages, as their influence on CVD development decreases as people get older.
Aims/introduction: Although several noninvasive predictive markers for fatty liver and metabolic markers have been used for fatty liver prediction, whether such markers can also predict metabolic-associated fatty liver disease (MAFLD) remains unclear. We aimed to examine the ability of existing fatty liver or metabolic markers to predict MAFLD.
Materials And Methods: Participants in a high-volume center in Tokyo were classified into groups with and without MAFLD, based on the presence of metabolic abnormalities and fatty liver diagnosed through abdominal ultrasonography, between 2008 and 2018.
Aims/introduction: Little is known about the relationship between cardiovascular health (CVH) metrics and the risk of developing prediabetes or diabetes. We examined the association of CVH metrics with the annual risk of developing prediabetes or diabetes.
Materials And Methods: We carried out this study including 403,857 participants aged 18-71 years with available data on fasting plasma glucose (FPG) data for five consecutive years and with normal FPG (<100 mg/dL) at the initial health checkup.
Background: Low body mass index (BMI) in older individuals with decreased kidney function is important because of its association with poor prognosis and frailty. Herein, we aimed to clarify the association between BMI and in-hospital mortality among older patients with non-dialysis-dependent chronic kidney disease (CKD) stratified by kidney function.
Methods: Using data from the Medical Vision Database, this multicentre cohort study included people aged ≥ 60 years with an estimated glomerular filtration rate of < 60 ml/min/1.
Background: Making lifestyle changes is an essential element of abdominal obesity (AO) reduction. To support lifestyle modification and self-management, we developed an information and communication technology-based self-management system-DialBeticsLite-with a fully automated dietary evaluation function for the treatment of AO.
Objective: The objective of this study was to evaluate the preliminary efficacy and feasibility of DialBeticsLite among Japanese office workers with AO.
Article Synopsis
- The study aimed to evaluate major complication rates after percutaneous liver biopsies (PLB) in pediatric patients, comparing those with native and transplanted livers.
- Utilizing Japan's Diagnosis Procedure Combination database, researchers analyzed data from 3584 PLBs performed on 1732 patients between 2010 and 2018.
- Results showed that major complications were more common in native liver biopsies (1.0%) than in transplanted liver biopsies (0.2%), with factors like age and medical conditions influencing complication rates.
Background The prevalence of hypertension subtypes changes with age. However, little is known regarding the age-dependent association of hypertension subtypes with incident heart failure (HF). Methods and Results We conducted an observational cohort study including 2 612 570 people (mean age, 44.
