STUDY OBJECTIVES Insomnia and short or long sleep duration are important comorbid conditions in adults with attention-deficit hyperactivity disorder (ADHD), but reports of the association vary. In a general population study, we evaluated the relationship between ADHD symptom severity, insomnia symptoms, and sleep duration in adults. METHODS Data were from the third wave of the Netherlands Men...

Our earlier studies on edentulous elderly subjects have shown associations of severe resorption in the mandibular residual ridge with female gender and systemic diseases. The aim of this study was to examine whether other factors also were related to residual ridge resorption (RRR). Among 177 edentulous elderly subjects effects on RRR were investigated with regard to history of edentulousness a...

OBJECTIVES This study aimed to investigate patients' willingness to initiate a preventive treatment and compared two established effect measures to the newly developed Delay of Events (DoE) measure that expresses treatment effect as a gain in event-free time. METHODS In this cross-sectional, randomized survey experiment in the general Swedish population,1079 respondents (response rate 60.9%) ...

The biological function of the stereoisomers of a-tocopherol is believed to depend on their bioavailability. Assessment of bioavailability within the body is therefore considered to be a good and easy way to predict biological value. The separation of a-tocopherol methyl ethers by chiral column HPLC is a good and easy tool with which to study the distribution of a-tocopherol stereoisomers. The ...

α-Tocopherol is the principal source of vitamin E, an essential nutrient that plays a crucial role in maintaining healthy brain function. Infant formula is routinely supplemented with synthetic α-tocopherol, a racaemic mixture of eight stereoisomers with less bioactivity than the natural stereoisomer RRR-α-tocopherol. α-Tocopherol stereoisomer profiles have not been previously reported in the h...

OBJECTIVE To determine whether the rates of nontraumatic dental condition (NTDC)-related emergency department (ED) visits are higher during the typical working hours of dental offices and lower during night hours, as well as the associated factors. METHODS We analyzed data from the National Hospital Ambulatory Medical Care Survey for 1997 through 2007 using multivariate binary and polytomous ...

Pure copper, specifically oxygen-free copper (OFC), is widely used in superconductive and low-temperature refrigeration technologies owing to its superior electrical thermal conductive properties at cryogenic temperatures. These properties, which can be expressed terms of the residual resistivity ratio (RRR), are associated with purity or impurity concentration. High-purity a low concentration ...

INTRODUCTION Inconsistency in the time trade-off (TTO) task in EQ-5D-5L occurs when a respondent gives a higher value to a logically worse health state, the occurrence of inconsistency compromises the quality of the data. It is not yet clear which factors are associated with individual level inconsistency. Relating inconsistency to the characteristics of the respondent, interviewer, and the int...

BACKGROUND Tumour necrosis factor (TNF) inhibitors enable tight control of disease activity in patients with rheumatoid arthritis (RA). Discontinuation of TNF inhibitors after acquisition of low disease activity (LDA) is important for safety and economic reasons. OBJECTIVE To determine whether infliximab might be discontinued after achievement of LDA in patients with RA and to evaluate progre...

BACKGROUND Little is known about the relations between dietary patterns, metabolic dysfunction, and left ventricular (LV) function. OBJECTIVE The objective was to examine associations of dietary patterns with LV mass and function and to explore the potential role of metabolic dysfunction in the association between diet and LV function. DESIGN Dietary patterns that maximally explained the va...
