Title: [Pulmonary Rehabilitation Before and After Lung Transplantation.][Article in German]
Authors: Kenn K, Sczepanski B.
Source: Pneumologie. 2011 Feb 22. [Epub ahead of print].

Summary: Kenn et al. present the importance, aims and specific features of rehabilitation prior to and following lung transplantation. Finally the therapeutic concept will be discussed with regard to the economic burden and the limited resources in lung transplantation.

Title: Rehabilitation in COPD patients admitted for exacerbation.
Authors: Clini E, Venturelli E, Crisafulli E.
Source: Pneumonol Alergol Pol. 2011;79(2):116-20.

Summary: This review updates the application of early pulmonary rehabilitation and main physical therapies both during hospital acute care and following discharge of COPD patients who have experienced exacerbation.

Title: Skeletal muscle effects of electrostimulation after COPD exacerbation: a pilot study.
Authors: Abdellaoui A, Préfaut C, Gouzi F, Couillard A, Coisy-Quivy M, Hugon G, Molinari N, Lafontaine T, Jonquet O, Laoudj-Chenivesse D, Hayot M.
Source: Eur Respir J. 2011 Feb 24. [Epub ahead of print].

Summary: Muscle dysfunction is a major problem in chronic obstructive pulmonary disease (COPD), particularly after exacerbations. Abdellaoui et al . studied whether neuromuscular electrostimulation (NMES) might be directly useful following an acute exacerbation and if such a therapy decreases muscular oxidative stress and/or alters muscle fibre distribution. This study shows that following COPD exacerbation, NMES is effective in counteracting muscle dysfunction and decreases muscle oxidative stress.

Title: Improvement of heart rate variability after exercise training and its predictors in COPD.
Authors: Camillo CA, Laburu VD, Gonçalves NS, Cavalheri V, Tomasi FP, Hernandes NA, Ramos D, Marquez Vanderlei LC, Cipulo Ramos EM, Probst VS, Pitta F.
Source: Respir Med. 2011 Feb 20. [Epub ahead of print].

Summary: Camillo et al. aimed to investigate changes in heart rate variability after two exercise training programs in patients with COPD and to investigate the determinants of these eventual changes. High-intensity exercise training improves heart rate variability at rest and during orthostatic stimulus in patients with COPD. Better baseline total HRV, muscle force and daily physical activity level are predictors of HRV improvements after the training program.

Authors: Arnold E, Bruton A, Donovan-Hall M, Fenwick A, Dibb B, Walker E.
Source: BMC Pulm Med. 2011 Feb 11;11:9.

Summary: The aim of this study was to obtain in-depth information about perceptions and use of prescribed ambulatory oxygen systems from patients with COPD to inform ambulatory oxygen design, prescription and management. Arnold et al. conclude that increased user involvement in both system development and service provision planning, could have avoided many of the difficulties highlighted by this study.

Problematic activities of daily life

Title: Development and validation of the living with chronic obstructive pulmonary disease questionnaire.
Authors: McKenna SP, Meads DM, Doward LC, Twiss J, Pokrzywinski R, Revicki D, Hunter CJ, Glendenning GA.
Source: Qual Life Res. 2011 Feb 11. [Epub ahead of print]

Summary: The purpose of the study was to develop a patient-based patient-reported outcome measure for COPD that captures the overall everyday impact of living with COPD from the patient's perspective. The Living with COPD is a new measure examining the everyday impact of living with COPD. It demonstrates good scaling properties and may prove valuable in understanding treatment benefits.

Skeletal muscles

Title: Evidence that a higher ATP cost of muscular contraction contributes to the lower mechanical efficiency associated with COPD: preliminary findings.
Authors: Layec G, Haseler LJ, Hoff J, Richardson RS.
Source: Am J Physiol Regul Integr Comp Physiol. 2011 Feb 9. [Epub ahead of print].

Summary: Layec et al. used (31)P-magnetic resonance spectroscopy ((31)P-MRS) to examine the energy cost and skeletal muscle energetics in six patients with COPD during dynamic plantar flexion exercise in comparison to six well-matched healthy control subjects. The results reveal, for the first time that in a small subset of patients with COPD a higher ATP cost of muscle contraction may substantially contribute to the lower mechanical efficiency previously reported in this population. In addition, it appears that some patients with COPD have preserved mitochondrial function and normal energy supply in lower limb skeletal muscle.
