Effect of postoperative physical training on activity after curative surgery for non-small cell lung cancer: a multicentre randomised controlled trial.

OBJECTIVE: To evaluate the effect of a combined hospital plus home exercise programme following curative surgery for non-small cell lung cancer (NSCLC). DESIGN: Randomised controlled trial. SETTING: Teaching hospital. PARTICIPANTS: One hundred and thirty-one subjects with NSCLC admitted for curative surgery. INTERVENTIONS: Participants were randomised to usual care or a hospital plus home exercise programme. OUTCOMES: The primary outcome was the between-group difference in physical activity 4 weeks after surgery. Secondary outcomes were the difference in quadriceps strength, exercise tolerance and quality of life [Short Form-36 (SF-36) and European Organisation for Research and Treatment of Cancer (EORTC) QLQ-LC13] from pre-operatively (baseline) to 4 weeks after surgery. RESULTS: The participants (n=131) had a mean age of 68 [standard deviation (SD) 11] years and mean forced expiratory volume in 1 second of 2.4 (SD 1.1)l. There were no significant differences in physical activity between the groups 4 weeks after surgery [mean difference adjusted for baseline 12minutes/day, 95% confidence interval (CI) -20.2 to 44.1]. In addition, there were no significant differences in total SF-36 or EORTC QLQ-LC13 scores from baseline to 4 weeks after surgery. Both groups had recovered their pre-operative walking distance 4 weeks after surgery, and there were no differences between the groups (mean difference in Incremental Shuttle Walk Test from baseline to 4 weeks after surgery (-26m, 95% CI -94.2 to 42.3). CONCLUSIONS: A hospital plus home exercise programme showed little benefit in unselected patients with NSCLC following surgery. Regardless of group allocation, the patients had recovered their pre-operative exercise tolerance levels by 4 weeks after surgery.

An exploratory study into the unmet supportive needs of breast cancer patients.

This study explores the unmet supportive needs of people with breast cancer attending a London NHS Foundation Trust Hospital. A mixed methods approach was used. One hundred and one patients completed a specially designed questionnaire focusing on their concerns in the previous week, and whether they felt they had been offered sufficient support from health professionals. Seven semi-structured interviews were then completed in order to gain insight into the need for future developments of services for patients with breast cancer. Pearson's chi-squared analysis was used to examine whether symptoms reported within 1 year of diagnosis differed from symptoms reported more than 1 year post diagnosis. Fatigue was the most common concern expressed (53%) with no significant difference between the two groups. Emotional concerns and pain were also highly reported (35% and 36%). Only 32% of the questionnaire participants reported that they had been offered support in dealing with their concerns. Most participants (65%) would have liked more support from the healthcare team. From the interviews it was clear that whilst there are gaps in services available, participants were not aware of the range of services already available for people with breast cancer. The results of this study have helped to inform service development, particularly around the management of fatigue.

Increased augmentation index in patients with cystic fibrosis.

Increased large artery stiffness occurs in a range of inflammatory conditions indicating an ageing of the vasculature and additionally being an independent risk factor for cardiovascular events. We determined large artery parameters in adults with cystic fibrosis (CF). 50 clinically stable adult patients with CF (mean+/-sd age 28.0+/-8.2 yrs) and 26 controls matched for age, sex and body mass index were studied. Central aortic blood pressure, augmentation index (AIx) and aortic pulse wave velocity (PWV) were determined using applanation tonometry. Lung function, diabetic status and C-reactive protein (CRP) were also determined. Mean+/-sd AIx was greater in patients than controls, 8.5+/-11.1% and -1.8+/-13.1%, respectively (p<0.001), while PWV was similar. Although AIx was greatest in the sub-group with CF-related diabetes (CFRD), it was also increased in the non-CFRD sub-group when compared with controls. In patients, AIx was related to log(10) CRP (r = 0.33) and forced vital capacity (r = -0.34; both p<0.05), and CRP remained predictive in multiple regression. AIx is increased in adults with CF, in the presence of a normal blood pressure and independent of diabetic status. AIx was related to the systemic inflammatory status. These findings have implications for management and require further exploration so that cardiovascular health can be maintained.

Poly(N-acryloylsarcosine methyl ester) protein-resistant surfaces.

A new class of protein-resistant film based on N-substituted glycine derivatives is described. Pulsed plasma deposited poly(N-acryloylsarcosine methyl ester) coatings are shown to be resistant toward the adsorption of fibrinogen and lysozyme. Deposition and UV irradiation of the polymer through a masked grid are found to be effective ways for generating negative and positive image protein arrays, respectively, onto a range of different substrate materials.
