Introduction: Acknowledging the evolved landscape in thoracic transplantation, professional employment becomes an important outcome measure to quantify the success of this costly procedure.
Objective: We aimed to assess rates of and characterize factors associated with professional employment in patients following thoracic transplantation, and create an evidence-base on the relationship between professional employment and relevant outcome parameters.
Methods: We systematically searched Medline, Cinahl, and GoogleScholar to identify studies published between 1998 and 2021 reporting on professional employment following heart and lung transplantation.
Background: Joint data analysis from multiple nutrition studies may improve the ability to answer complex questions regarding the role of nutritional status and diet in health and disease.
Objective: The objective was to identify nutritional observational studies from partners participating in the European Nutritional Phenotype Assessment and Data Sharing Initiative (ENPADASI) Consortium, as well as minimal requirements for joint data analysis.
Methods: A predefined template containing information on study design, exposure measurements (dietary intake, alcohol and tobacco consumption, physical activity, sedentary behavior, anthropometric measures, and sociodemographic and health status), main health-related outcomes, and laboratory measurements (traditional and omics biomarkers) was developed and circulated to those European research groups participating in the ENPADASI under the strategic research area of "diet-related chronic diseases.
Background: The valid estimation of the usual dietary intake remains a challenge till date. We applied the method suggested by the National Cancer Institute (NCI) to data from the 2nd Bavarian Food Consumption Survey (BVS II) and compared it to an individual means approach.
Methods: Within the cross-sectional BVS II, 1,050 Bavarian residents aged 13-80 years participated in a personal interview and completed three 24-h dietary recalls by telephone interview.
Background/objectives: Only few epidemiologic studies examined sleep characteristics in relation to dietary behaviour. Our aim was to analyse associations of sleep duration, midpoint of sleep and sleep quality with dietary intake among the Bavarian population.
Subjects/methods: Within the cross-sectional Bavarian Food Consumption Survey II, 1050 subjects aged 13-81 years were recruited.
Background/objectives: The aim of this systematic review and meta-analysis was to assess the effect of season on food intake from selected food groups and on energy intake in adults.
Subjects/methods: The search process was based on selecting publications listed in the following: Medline, Scopus, Web of Science, Embase and Agris. Food frequency questionnaires, 24-h dietary recalls and food records as methods for assessment of dietary intake were used to assess changes in the consumption of 11 food groups and of energy intake across seasons.
