The effect of atmospheric pressure on oxygen saturation and dyspnea: the Tromsø study.

A drop in atmospheric pressure, as observed at high altitudes, leads to decreased oxygen saturation. The effect of regular changes in barometric pressure at sea level has never been studied in a general population. A cohort of adults aged 40 years were examined with pulse oximetry at two separate visits, and the local barometric pressure was available from the local weather station.

'Secretly, it's a competition': a qualitative study investigating what helped employees quit smoking during a workplace smoking cessation group training programme with incentives.

Objectives: Smoking cessation programmes in combination with financial incentives have shown to increase quit rates in smokers, but it is not clear which elements of this intervention help smokers to succeed in their quit attempt. The aim of this study was to explore the view of successful and unsuccessful quitters about which factors had affected their ability to quit smoking.

Design: Semistructured qualitative interviews were conducted and analysed using the Framework method.
