Metabolomic data presents challenges for epidemiological meta-analysis: a case study of childhood body mass index from the ECHO consortium.

Introduction: Meta-analyses across diverse independent studies provide improved confidence in results. However, within the context of metabolomic epidemiology, meta-analysis investigations are complicated by differences in study design, data acquisition, and other factors that may impact reproducibility.

Objective: The objective of this study was to identify maternal blood metabolites during pregnancy (> 24 gestational weeks) related to offspring body mass index (BMI) at age two years through a meta-analysis framework.

The Nurses Self-Concept Instrument (NSCI): assessment of psychometric properties for Australian domestic and international student nurses.

Background: Professional self-concept is a critical driver of job satisfaction. In Australia, as international nursing enrolments rise, nursing is increasingly characterised by a professional body of international nurses who may differ from domestic Australian nurses in their nursing self-concept. At present, no psychometrically sound instrument for assessing nursing self-concept for Australian domestic and international nursing students is available.

The nurses' self-concept instrument (NSCI): a comparison of domestic and international student nurses' professional self-concepts from a large Australian University.

Professional self-concept is a critical driver of job satisfaction. In Australia, as international nursing enrolments rise, nursing is increasingly characterised by a professional body of international nurses who may differ from domestic Australian nurses in their nursing self-concept. At present, little is known about the extent to which domestic and international students nurses' self-concepts may differ.
