Identifying correlates of breaks in occupational sitting: a cross-sectional study

Office workers are commonly targeted in interventions to modify their sitting behaviour, yet there is limited evidence of the correlates of breaks in sitting to inform intervention development. This study identifies the individual, workplace and spatial configuration correlates of the frequency of breaks in sitting (number/hour) in office workers (n?=?5531) stratified by office type (private-enclosed, shared, open plan). All behaviours and potential correlates were measured via self-report using an online cross-sectional survey. Regression analyses revealed age was the only socio-demographic characteristic associated with frequency of breaks in sitting in all office types. Greater job autonomy and local connectivity were positively associated with frequency of breaks in sitting in shared and open-plan offices. In open-plan offices co-worker proximity was negatively associated with frequency of breaks in sitting. Co-worker visibility was positively associated with frequency of breaks in sitting in all office types. This study demonstrates that individual, workplace and spatial configuration factors are all associated with the frequency of breaks in sitting and that these relationships differ by office type. These observations extend prior studies that have only examined correlates at a single level (e.g. the individual). This evidence could be useful to guide future interventions in the design of workplaces to increase breaks in sitting and workers’ physical activity.     

Thoracoscopic-assisted pulmonary resection in lung cancer

BACKGROUND: Thoracoscopic-assisted pulmonary resection for lung cancer is controversial. The appropriateness of this approach has to be compared with the golden standard of an open resection. METHODS: This study consists of 66 patients with a clinical stage 1 disease. A thoracoscopic exploration was executed in 41 patients. Only in 16 cases was a thoracoscopic resection finally possible. The clinical and pathological TNM classification, the histological types and the surgical procedure are reported. The reasons for conversion are documented. RESULTS: To investigate the appropriateness of the thoracoscopic approach we evaluated only the pathologically proven stage 1 disease in both groups. Postoperative complications, hospital stay and survival are compared. CONCLUSION: Until now we can conclude that there is no adverse effect on survival because of the thoracoscopic approach.
