Rehabilitation in patients with radically treated respiratory cancer: A randomised controlled trial comparing two training modalities.

INTRODUCTION: The evidence on the effectiveness of rehabilitation in lung cancer patients is limited. Whole body vibration (WBV) has been proposed as an alternative to conventional resistance training (CRT). METHODS: We investigated the effect of radical treatment (RT) and of two rehabilitation programmes in lung cancer patients. The primary endpoint was a change in 6-min walking distance (6MWD) after rehabilitation. Patients were randomised after RT to either CRT, WBVT or standard follow-up (CON). Patients were evaluated before, after RT and after 12 weeks of intervention. RESULTS: Of 121 included patients, 70 were randomised to either CON (24), CRT (24) or WBVT (22). After RT, 6MWD decreased with a mean of 38m (95% CI 22-54) and increased with a mean of 95m (95% CI 58-132) in CRT (p<0.0001), 37m (95% CI -1-76) in WBVT (p=0.06) and 1m (95% CI -34-36) in CON (p=0.95), respectively. Surgical treatment, magnitude of decrease in 6MWD by RT and allocation to either CRT or WBVT were prognostic for reaching the minimally clinically important difference of 54m increase in 6MWD after intervention. CONCLUSIONS: RT of lung cancer significantly impairs patients' exercise capacity. CRT significantly improves and restores functional exercise capacity, whereas WBVT does not fully substitute for CRT

Le sevrage tabagique: une nouvelle molécule orale, la varenicline (Champix).

Varenicline orally administered nicotine acetylcholine receptor partial agonist is approved by the US FDA and the MEA for use as an aid to smoking cessation therapy. Varenicline is more effective than bupropion but does not reduce weight gain after cessation. The superiority of de varenicline on the nicotine is not demonstrated. Nausea is a frequent adverse effect. The long term safety of varenicline is unknown. The major weapons for smoking cessation are represented by the motivation of the patient and a long term psychotherapy. As to the subject of drugs, varenicline is situated in second position, after the failure of a nicotine substitute.English AbstractJournal ArticleSCOPUS: ar.jinfo:eu-repo/semantics/publishe

Two sites of airway obstruction identified by post-bronchodilation change of exhaled nitric oxide in COPD patients

Background: We have shown that the change of exhaled nitric oxide (FENO) after bronchodilation allows to identify the site of airway obstruction in asthma: FENO stability, increase, or decrease reflects obstruction relief by bronchodilation up to central, pre-acinar and intra-acinar airways (1).Aim: To investigate whether FENO change after bronchodilation is able to identify different sites of airway obstruction in COPD patients.Methods: FENO, FEV1, and the slope (S) of phase III of He, and SF6 from a single-breath test were measured in 41 stable COPD patients with median(range) FEV1 of 48(20-78)%predicted before and 20 minutes after inhalation of 400 µg salbutamol. SHe and SSF6 decrease reflects pre- and intra-acinar obstruction relief respectively. Changes (Δ) were expressed as a percentage of baseline.Results: No FENO change (info:eu-repo/semantics/publishe

Les techniques de médecine physique peuvent-elles pallier la distension?

The authors review the literature concerning the possibilities of modifying the mechanical characteristics of the respiratory system with breathing retraining and other chest physiotherapy intervention. Breathing retraining techniques with prolonged and active expiration induce increased work of breathing and do not help diaphragmatic function. Only pursed lips breathing seems to produce some mechanical advantages. The seated and forward position with fixed arms may reduce dyspnea but this does not appear to be caused by a decrease in operating lung volumes. By contrast, the dorsal decubitus position may reduce hyperinflation, giving some mechanical advantage to the diaphragm but does not reduce dyspnea and is not a position spontaneously adopted by patients. General muscular training may reduce ventilatory demand, and by reducing respiratory frequency lead to a decrease in the end expiratory lung volume; therefore inducing improvement in exercise tolerance. © 2009 SPLF.

Modification of COPD presentation during the last 25 years.

During the last decades progress has been made in the treatment of Chronic Obstructive Pulmonary Disease (COPD). We compared a random sample of patients admitted for an exacerbation in the period 2001-2005 (n = 101), with a random sample of patients hospitalized for the same reason in the period 1980-1984 (n = 51). Patients of the 2001-2005 cohort had a lower FEV1 (48 ± 3 vs. 41 ± 2% predicted, p = 0.01) for similar mean age, gender and body- mass index when compared to the historical sample. Co-morbidities, according to the Charlson's index, were more prevalent in the 2001-2005 cohort compared to the 1980-1984 cohort, with a reduction of hemoglobin (13.9 ± 0.2 gr/dl vs. 14.9 ± 0.2, p < 0.01) and higher prevalence of anemia in the most recent cohort. We found an increase in the use of cardiovascular drugs and respiratory medications over time with exception for the long-term use of oxygen. Despite lower FEV1 and more prevalent co-morbidities, no difference in length of hospitalization (13.6 ± 1.4 days vs. 12.7 ± 0.7 days, p = 0.52) and 30 months survival post-exacerbation was noted (66.6% vs. 69.3%, p = 0.85). Over the course of 20 years, the presentation of COPD patients admitted for an exacerbation seems to be changed towards a more severe phenotype with lower FEV1 and more co-morbidities. As the length of hospitalization and the overall survival were not different between the two samples, a currently improved management of COPD can be hypothesized.Comparative StudyJournal Articleinfo:eu-repo/semantics/publishe
