BACKGROUND In the Netherlands, the proportion of patients with amyotrophic lateral sclerosis (ALS) who choose the option of euthanasia or physician-assisted suicide (PAS) is relatively high (20%). The objective of this study was to determine which factors influence end-of-life practices in ALS and whether rates are changing over time. METHODS In a cohort(More)
BACKGROUND To assess whether the premorbid dietary intake of fatty acids, cholesterol, glutamate or antioxidants was associated with the risk of developing amyotrophic lateral sclerosis (ALS). METHODS Patients referred to our clinic during 2001-2002, who had definite, probable or possible ALS according to El Escorial criteria, without a familial history(More)
IMPORTANCE Because dietary intake may influence pathophysiologic mechanisms in sporadic amyotrophic lateral sclerosis (ALS), the association between premorbid dietary intake and the risk of sporadic ALS will provide insight into which mechanisms are possibly involved in ALS pathophogenesis. OBJECTIVE To systematically determine the association between(More)
BACKGROUND The objective was to develop an index based on the Dutch Guidelines for a healthy Diet of 2006 that reflects dietary quality and to apply it to the Dutch National Food Consumption Survey (DNFCS) to examine the associations with micronutrient intakes. METHODS A total of 749 men and women, aged 19-30 years, contributed two 24-hour recalls and(More)
BACKGROUND Invalid information on dietary intake may lead to false diet-disease associations. This study was conducted to examine the relative validity of the food frequency questionnaire (FFQ) used to assess dietary intake in the Leiden Longevity Study. METHODS A total of 128 men and women participating in the Leiden Longevity Study were included in the(More)
BACKGROUND In Western countries the prevalence of cardiovascular disease (CVD) is often higher in non-Western migrants as compared to the host population. Diet is an important modifiable determinant of CVD. Increasingly, dietary patterns rather than single nutrients are the focus of research in an attempt to account for the complexity of nutrient(More)
The authors automated the selection of foods in a computer system that compiles and processes tailored FFQ. For the selection of food items, several methods are available. The aim of the present study was to compare food lists made by MOM2, which identifies food items with highest between-person variance in intake of the nutrients of interest without taking(More)
BACKGROUND Postpartum weight retention affects many women and increases the risk of becoming overweight. The research objective was to study modifiable factors contributing to weight change at one year postpartum. METHODS In this prospective cohort, postpartum behavior, such as physical activity, sedentary behavior, sleep, and intake of total energy,(More)
BACKGROUND Differences in dietary patterns between ethnic groups have often been observed. These differences may partially be a reflection of differences in socio-economic status (SES) or may be the result of differences in the direction and strength of the association between SES and diet. OBJECTIVE We aimed to examine ethnic differences in dietary(More)
PURPOSE We investigated whether group-level bias of a 24-h recall estimate of protein and potassium intake, as compared to biomarkers, varied across European centers and whether this was influenced by characteristics of individuals or centers. METHODS The combined data from EFCOVAL and EPIC studies included 14 centers from 9 countries (n = 1,841). Dietary(More)
