[Pulmonary lipofibroblasts in adults and alveolar regeneration in emphysema]. / Lipofibroblastes pulmonaires chez l'adulte et régénération alvéolaire au cours de l'emphysème.

Lipofibroblasts form a sub-population of fibroblasts located in the mesenchymal alveolar stem cell niche. They show close proximity with alveolar epithelial type 2 cells and play a key role in alveolar development and lung homeostasis. Their role in various diseases such as acute respiratory distress syndrome, pulmonary fibrosis and emphysema is progressively better understood. Through the activation of signaling pathways such as PPARg lipofibroblasts may help to induce endogenous alveolar regeneration.

[Nurse practitioners as key actors in pulmonary rehabilitation for chronic obstructive pulmonary disease]. / L'infirmier en pratique avancée, un acteur-clé dans le développement de la réadaptation respiratoire chez le patient atteint de BPCO.

INTRODUCTION: While pulmonary rehabilitation is registered in the COPD management guidelines with a high level of evidence, it is not adequately performed in accordance with patients' needs. Advanced nurse practitioners (IPA, in French) provide expertise enabling improved access and enhanced implementation of rehabilitation programs. Based on foreign experience, the present study has been designed to propose avenues for the development of more effective practices in France. METHODS: Using Google Scholar and Pubmed databases, a search algorithm was used to identify international publications from 2003 to 2022 dealing with the role of nurse practitioners (IP, in French) in respiratory rehabilitation for COPD patients. RESULTS: Fourteen articles, mainly from English-speaking countries, were analysed. The involvement of nurse practitioners in pulmonary rehabilitation is very broad-based, their main missions being initial disease assessment, therapeutic education, improved professional sensitivity and patient follow-up at all stages of a rehabilitation program. CONCLUSION: Nurse practitioners have a major role in the implementation of pulmonary rehabilitation programs for COPD patients. Their involvement at different levels can improve access and success of programs over time.

[Predictive factors for skeletal-related events in lung cancer]. / Facteurs prédictifs de survenue d'évènements osseux dans le cancer bronchique.

INTRODUCTION: Skeletal-related events (SRE) are common in patients with bone metastatic lung cancer and have a negative impact on quality of life and survival. The objective of this study is to identify predictive factors for SRE occurrence among this population. METHODS: We conducted a 3-year retrospective study including 100 lung cancer patients with bone metastasis. RESULTS: Eighty-two patients presented at least one SRE (69.5% at baseline). The median occurrence for SRE was 4.5 months and severe bone pain was the most common SRE (56%). The alkaline phosphatase serum level>120IU/L (hazard ratio [sHR]=2.8; 95% confidence interval (CI) [1.5-5.4]; P=0.002) and calcemia>2.6mmol/L ([sHR]=9.7; 95% CI [5.1-18.4]; P<0.001) were identified as risk factors for SRE occurrence while the presence of an initial SRE was associated with a decrease of this risk ([sHR]=0.2; 95% CI [0.1-0.4]; P<0.001). CONCLUSION: The elevated alkaline phosphatase serum level and hypercalcemia are risk factors for SRE occurrence in bone metastatic lung cancer patients and should be used as biomarkers to adapt current medical practice for these patients.

[Early determinants of chronic obstructive pulmonary disease: Lung regeneration, a new therapeutic target?] / Déterminants précoces de la bronchopneumopathie chronique obstructive : la régénération pulmonaire, une nouvelle piste thérapeutique ?

Chronic obstructive pulmonary disease, a disease of increasing incidence, is related mainly to smoking. Although symptoms only appear at adulthood, the disease can develop from early life events. For example, bronchopulmonary dysplasia, which occurs in preterm infants, is characterized by airspace enlargement and could lead to late lung consequences. Once the lesions are established, no curative treatment is available. Stimulating lung regeneration from endogenous stem cells is therefore an exciting research domain, particularly through the activation of the mesenchymal contingent located in the lung stem cell niche.

[Complementary and alternative medicine use by lung cancer patients]. / Le recours aux médecines « complémentaires et alternatives ¼ par les patients atteints d'un cancer bronchique.

INTRODUCTION: Complementary and alternative medicine (CMA) use is frequent among cancer patients. Only few results are available about lung cancer patients. The aim of this study was to evaluate how often the CMA were used by lung cancer patients and to define the type of CMA used. METHODS: Every lung cancer patients with an ongoing chemotherapy in the respiratory department of the University Hospital of Nancy were approached between November 2014 to July 2015. A detailed and anonymous survey was conducted and the socioeconomic characteristics were collected from medical records. RESULTS: Ninety-one patients were questioned. On 82 patients having answered, 19.5 % had used at least a CMA. The main CMA used was the physical exercise in 50 % of the patients. CMA users were significantly younger with a mean age of 56.4 years versus 65.4 years (P=0.0007). More than half patients did not indicate to their specialist that they used a CMA. The main information source was the circle of acquaintances. CONCLUSIONS: CMA use is frequent among lung cancer patients. The physical exercise is quoted most of the time among the various CMA. There is a real lack of communication on the subject between the physician and the patient. It is thus imperative that the pulmonologists give much interest to these practices in order to give better advices and to reinforce the patient-physician relationship.
