Procedural skills of Australian general practice registrars: A cross-sectional analysis.

Background: Procedural skills are an essential component of general practice vocational training. The aim of this study was to investigate the type, frequency and rural or urban associations of procedures performed by general practice registrars, and to establish levels of concordance of procedures performed with a core list of recommended procedural skills in general practice training.

Methods: A cross-sectional analysis of a cohort study of registrars' consultations between 2010 and 2016 was undertaken.

Occurrence and concentration of caffeine in Oregon coastal waters.

Caffeine, a biologically active drug, is recognized as a contaminant of freshwater and marine systems. We quantified caffeine concentrations in Oregon's coastal ocean to determine whether levels correlated with proximity to caffeine pollution sources. Caffeine was analyzed at 14 coastal locations, stratified between populated areas with sources of caffeine pollution and sparsely populated areas with no major caffeine pollution sources.
