Pitavastatin Compared with Differential Intervention Trial by Standard Therapy on Cardiovascular Events in Patients with Dyslipidemia on Chronic Hemodialysis (DIALYSIS): A Randomized Controlled Trial.

Introduction: Statin has been reported to reduce cardiovascular events. However, the comparative efficacy of statin with standard therapy on cardiovascular events has not been sufficiently reported in patients on chronic hemodialysis. Thus, this study aimed to compare the effects of pitavastatin and standard therapy on mortality and cardiovascular events in chronic hemodialysis patients with dyslipidemia in Japan.

Smart Gene™ as an effective non-invasive point-of-care test to detect Helicobacter pylori clarithromycin-resistant mutation.

Background And Aim: Smart Gene™ was developed based on the concept of point-of-care genetic testing. We evaluated the detection performance of a reagent for Helicobacter pylori (H. pylori) clarithromycin (CAM)-resistant mutation assessment and determined the association between the results of Smart Gene™ and those of eradication therapy for H.

Effects of Screen Viewing Time on Sleep Duration and Bedtime in Children Aged 1 and 3 Years: Japan Environment and Children's Study.

This study aimed to clarify the effects of television/digital versatile disc (TV/DVD) viewing time and portable electronic device (PED) usage time on sleep duration and bedtime and the difference between the effects of TV/DVD and PED on sleep. The effect of TV/DVD viewing time or PED usage time on sleep duration and bedtime was analyzed using a multiple logistic regression analysis adjusted for covariates. A total of 74,525 participants were included in the analysis, using data from Japan Environment and Children's Study.

Association between maternal insecticide use and otitis media in one-year-old children in the Japan Environment and Children's Study.

Otitis media (OM) is common among young children and is related to hearing loss. We investigated the association between maternal insecticide use, from conception to the first and second/third trimesters, and OM events in children in the first year of age. Data from Japan Environment and Children's Study were used in this prospective cohort study.

Early Developmental Signs in Children with Autism Spectrum Disorder: Results from the Japan Environment and Children's Study.

Autism spectrum disorder (ASD) is a developmental disability in early childhood. Early identification and intervention in children with ASD are essential for children and their families. This study aimed to identify the earliest signs of ASD.

Prevalence estimates of Helicobacter species infection in pancreatic and biliary tract cancers.

Background: Helicobacter pylori infection is a well-established risk factor for gastric cancer and has been linked to other gastrointestinal diseases, including pancreatic and biliary tract cancers; however, the relevance of enterohepatic non-H. pylori helicobacters to the pathophysiology of these diseases remains unclear.

Materials And Methods: We estimated the prevalence of two enterohepatic non-H.

Lifetime incidence risk for gastric cancer in the Helicobacter pylori-infected and uninfected population in Japan: A Monte Carlo simulation study.

Helicobacter pylori (H. pylori) infection is considered the leading cause of gastric cancer. Gastric cancer is currently a common cancer with high incidence and mortality rates, but it is expected that the incidence rate will gradually decrease as the H.

Association between house renovation during pregnancy and wheezing in the first year of life: The Japan environment and children's study.

Background: Wheezing is a common symptom in infants, which may occasionally develop into asthma. There are many factors related to infant wheezing, including anatomical features, viral infections, and passive smoking. There are only a few reports on the association between renovation and pregnancy worldwide, and reports on this association are inadequate in Japan.

Emotional and behavioral problems in pediatric patients with migraine and tension-type headache.

Objective: This study aimed to investigate the associations between psychopathological characteristics of children and adolescents with primary headache, as measured by the Strengths and Difficulties Questionnaire (SDQ), and treatment outcomes.

Methods: A cohort study was conducted on 124 pediatric patients with primary headache. At the first consultation, the SDQ was completed by the parents.

An approach to exploring associations between hospital structural measures and patient satisfaction by distance-based analysis.

Background: Patient satisfaction studies have explored domains of patient satisfaction, the determinants of domains, and score differences of domains by patient/hospital structural measures but reports on the structure of patient satisfaction with respect to similarities among domains are scarce. This study is to explore by distance-based analysis whether similarities among patient-satisfaction domains are influenced by hospital structural measures, and to design a model evaluating relationships between the structure of patient satisfaction and hospital structural measures.

Methods: The Hospital Consumer Assessment of Healthcare Providers and Systems 2012 survey scores and their structural measures from the Hospital Compare website reported adjusted percentages of scale for each hospital.
