In conclusion , preoperative exercise-based training improves pulmonary function before surgery and reduces in-hospital length of stay and postoperative complications after lung resection surgery for lung cancer
Lung cancer is the leading cause of cancer-related death worldwide .
For early stages of the disease , lung resection surgery remains the best treatment with curative intent , but significant morbidity is associated , especially among patients with poor pulmonary function and cardiorespiratory fitness .
In those cases , the implementation of a preoperative exercise-based intervention could optimize patient 's functional status before surgery and improve postoperative outcomes and enhance recovery .
The aim of this systematic review is to provide the current body of knowledge regarding the effectiveness of a preoperative exercise-based intervention on postoperative and functional outcomes in patients with lung cancer su bmi tted to lung resection surgery .
Newcastle-Ottawa Scale: comparing reviewers’ to authors’ assessments
Background Lack of appropriate reporting of method ological details has previously been shown to distort risk of bias assessment s in r and omized controlled trials . The same might be true for observational studies . The goal of this study was to compare the Newcastle-Ottawa Scale ( NOS ) assessment for risk of bias between review ers and authors of cohort studies included in a published systematic review on risk factors for severe outcomes in patients infected with influenza . Methods Cohort studies included in the systematic review and published between 2008–2011 were included . The corresponding or first authors completed a survey covering all NOS items . Results were compared with the NOS assessment applied by review ers of the systematic review . Inter-rater reliability was calculated using kappa ( K ) statistics . Results Authors of 65/182 ( 36 % ) studies completed the survey . The overall NOS score was significantly higher ( p < 0.001 ) in the review ers ’ assessment ( median = 6 ; interquartile range [ IQR ] 6–6 ) compared with those by authors ( median = 5 , IQR 4–6 ) . Inter-rater reliability by item ranged from slight ( K = 0.15 , 95 % confidence interval [ CI ] = −0.19 , 0.48 ) to poor ( K = −0.06 , 95 % CI = −0.22 , 0.10 ) . Reliability for the overall score was poor ( K = −0.004 , 95 % CI = −0.11 , 0.11 ) . Conclusions Differences in assessment and low agreement between review ers and authors suggest the need to contact authors for information not published in studies when applying the NOS in systematic review
