This narrative review focuses on the most recent data concerning lung function changes during healthy pregnancy. The major findings are as follows: pregnancy is associated with a reduction in static lung volumes reaching 20% of residual functional capacity; it is also associated with chronic alveolar hyperventilation; lastly, it is not associated with significant changes in variables measured by spirometry such as vital capacity, forced expiratory volume in one second and peak expiratory flow, or airway resistance.

AIM: The aim of the present study is to present the epidemiology of pre-XDR and XDR TB and the evolution over time of patients with multidrug-resistant TB. METHODS: This retrospective study covered the activities from 2019 to 2022 of the Nkembo anti-tuberculosis center. RESULTS: Fifteen patients were eligible, including 11 (73.3%) pre-XDR patients and 4 (26.7%) XDR-TB patients. Three (20.0%) patients had HIV/TB co-infection. The sample consisted of 7 men (46.7%) and 8 women (53.3%), a sex ratio (M/F) of 0.87. The average age was 35.6 years, and the median 34 years, with extremes of 23 and 60 years. Eight patients (53.3%) represented new cases of pre-XDR or XDR-TB tuberculosis. The majority (60%; n=9) came from deprived neighborhoods with widespread promiscuity. The therapeutic success rate among pre-XDR patients was 4 (36.4%) versus 2 (50.0%) among XDR-TB patients. Reported mortality occurred 5 (33.3%) patients during treatment, including 3 pre-XDR and 2 XDR-TB patients. In all cases, they died before the end of the first trimester of follow-up. CONCLUSION: The high frequency of primary pre-extensively drug-resistant tuberculosis underscores the pervasiveness of resistance to anti-tuberculosis drugs and underlines a pressing need for detection of contact cases and early treatment.

The objective of this study was to evaluate the different practices in our center regarding mediastinal lymph node sampling in lung cancer patients. METHODS: Data were collected from patients having undergone mediastinal lymph node sampling by video-assisted-mediastinoscopy (VM) or by endobronchial ultrasound (EBUS) in our center between August 2020 and July 2023. The modalities of the two procedures and their diagnostic accuracy were analyzed, as was their evolution over time. RESULTS: The 362 patients comprised 217 who were sampled by EBUS and 145 by VM. Overall, the procedures became more frequent, with EBUS tending to supersede VM. The number of harvested lymph nodes gradually grew, and less unforeseen lymph node invasion and upstaging occurred. CONCLUSION: The arrival in our center of endobronchial ultrasound yielded an overall increase of lymph node sampling despite a decrease in the number of mediastinoscopy procedures performed. Reinforced compliance with guidelines is needed to improve the diagnostic accuracy of these techniques and to better ensure quality of care.

As they are carried out during spontaneous breathing, oscillometry measurements do not require forced breathing maneuvers or the patient's active cooperation. The technique is complementary to conventional pulmonary function testing methods for the investigation of respiratory function, diagnosis and monitoring of respiratory diseases, and assessment of response to treatment. The present review aims to describe the theoretical foundations and practical methodology of oscillometry. It describes the gaps in scientific evidence regarding its clinical utility, and provides examples of current research and clinical applications.

METHODS: Outreach to the public occupying outdoor spaces led to immediate collection of responses over the course of 13 actions carried out in November 2022, a tobacco-free month. RESULTS: Thirty-two percent of the persons interrogated were smokers, 38% among patients, 26% among professionals and 18% among nursing students. A majority expressed support for smoke-free building entrances, which were viewed by half of the smokers as an encouragement to quit or cut down on their consumption. However, a quarter of participants anticipated difficulties, particularly the "heaviest" smokers. In the psychiatry sector, 54% were smokers, and they were relatively unfavorable to the initiative. As for non-smokers, most voiced discomfort regarding the smell of tobacco, the infiltration of smoke in indoor spaces, passive smoking, a negative image of the hospital, and the detrimental ecological impact. CONCLUSIONS: The tobacco-free hospital entrance initiative is relevant and of benefit to hospitals. In order to succeed, it must involve all stakeholders, whether they are users or professionals, in a concerted attempt to optimize assistance to smokers wishing to quit, by applying an educational and synergistic approach at all levels.

Monitoring of the French multicenter Asbestos-Related Disease Cohort (ARDCO), which ensures post-occupational medical surveillance of subjects having been exposed to asbestos, provides information on (1) the medico-legal steps taken following screening by computed tomography (CT) for benign thoracic diseases, and (2) recognition of OD as a causal factor in malignant diseases. METHODS: OD recognition - and possible compensation - was analyzed in July 2021 among 13,289 volunteers in the cohort recruited between 2003 and 2005. RESULTS: Fifteen percent of the subjects in the cohort were found to have at least one recognized asbestos-related OD (78.2% benign pleural disease, 10.3% asbestosis, 14.2% lung cancer, and 6.0% mesothelioma). Only 58% of pleural plaques reported by the radiologist who performed the CT resulted in their recognition as ODs. On a parallel track, 88.7% of the mesotheliomas identified based on French National health insurance data and 46.9% of lung cancers were recognized as ODs. CONCLUSIONS: This study confirms the feasibility of a system designed to facilitate recognition, leading to possible compensation, of asbestos-related occupational diseases. The system could be improved by better training of the medical actors involved.

Low-dose MTX (MTX-LD) is associated with a risk of haematological, hepatic, gastrointestinal and pulmonary toxicity, which may up until now have limited its use. STATE OF THE ART: In RA, data from retrospective cohorts have reported a possible excess risk of methotrexate toxicity in cases of underlying interstitial lung disease (ILD). However, recent prospective and retrospective multicentre studies have found no such increased risk, and have reassuringly concluded that MTX-LD can be prescribed in cases of RA-associated ILD (RA-ILD). PERSPECTIVES AND CONCLUSIONS: Current recommendations are not to delay the introduction of MTX in patients with RA at risk of developing ILD or in the presence of RA-ILD with mild to moderate respiratory impairment.

Bulbar involvement and cough weakness contribute to respiratory morbidity and mortality. ALS-related respiratory failure significantly affects quality of life and is the leading cause of death. Non-invasive ventilation (NIV), which is the main recognized treatment for alleviating the symptoms of respiratory failure, prolongs survival and improves quality of life. However, the optimal timing for the initiation of NIV is still a matter of debate. NIV is a complex intervention. Multiple factors influence the efficacy of NIV and patient adherence. The aim of this work was to develop practical evidence-based advices to standardize the respiratory care of ALS patients in French tertiary care centres. METHODS: For each proposal, a French expert panel systematically searched an indexed bibliography and prepared a written literature review that was then shared and discussed. A combined draft was prepared by the chairman for further discussion. All of the proposals were unanimously approved by the expert panel. RESULTS: The French expert panel updated the criteria for initiating NIV in ALS patients. The most recent criteria were established in 2005. Practical advice for NIV initiation were included and the value of each tool available for NIV monitoring was reviewed. A strategy to optimize NIV parameters was suggested. Revisions were also suggested for the use of mechanically assisted cough devices in ALS patients. CONCLUSION: Our French expert panel proposes an evidence-based review to update the respiratory care recommendations for ALS patients in daily practice.

Whatever the pathology responsible for respiratory symptoms and/or functional impairment, repeated PFTs make it possible to establish a prognosis (pulmonary function trajectories…) and to orient preventive interventions. PFT can be performed routinely from the age of three years, provided that the following requirements are met: suitable techniques and equipment, staff trained to apply the techniques and to receive young children, reference values for each technique indicating the limits of normal values and of between-test significant variation. From the age of three, children can be subjected to tidal breathing measurement of: resistance of the respiratory system (oscillometry, Rrs; airflow interruption, Rint) or of airways specific resistance (sRaw) and functional residual capacity (by applying a dilution technique). With maturity, the child will become capable of mobilizing his or her slow vital capacity to measure total lung capacity (TLC), once again by applying a dilution technique, then later by breathing against a closed shutter (plethysmography TLC and Raw). Finally, the child will be able to carry out forced expiration (forced spirometry) along with all of the other PFTs. It is important to take into account the paediatric adaptations specified in the international recommendations regarding the performance, reproducibility and quality of PFTs targeting this population.

Women experience greater dyspnea and a more impaired quality of life. The main objective of this study was to assess the effect of gender on dyspnea during a pulmonary rehabilitation program (PRP). METHODS: Retrospective study including COPD patients having participated in PRPs. The following data were analyzed according to gender before and after a PRP: dyspnea, quality of life, anxiety and depression, exercise capacity, muscle function (quadriceps and inspiratory muscles). RESULTS: More than 500 patients (252 men and 252 women) were included. We did not find a significant effect of gender on the evolution of dyspnea, anxiety or depressive disorders, exercise capacity, inspiratory muscle strength, or overall quality of life score. That said, we found a possible effect on the sub-scores of the quality of life questionnaire, and regarding quadriceps strength. All criteria improved during the program in both groups. CONCLUSIONS: During a PRP, gender does not impact the evolution of dyspnea. While women may nonetheless benefit to a greater extent in terms of quality of life sub-scores (impact, activities, symptoms) and quadriceps strength, these results still require confirmation.

This study aims to assess adherence to chest physiotherapy in adults with cystic fibrosis who not treated with tritherapy and to analyze the impact of certain factors on adherence. METHODS: Thus is a cross-sectional study, conducted using a questionnaire and a physiotherapy evaluation. Adherence to this treatment was measured in terms of quantitative and qualitative aspects. The impact on adherence of 15 factors was then assessed. RESULTS: Only 47% of patients could be considered as adherent, with a significant disparity between a quantitative and qualitative assessment. Gender, working time, pathology severity, the fact of being regularly followed by a physiotherapist, the perceived benefit of the sessions and their replacement by physical activity, seem associated with adherence to this treatment. CONCLUSIONS: Taking into account the qualitative aspect of the sessions, our study reveals a low rate, in our cohort, of adherence to respiratory physiotherapy, and highlights six factors likely to predominate. Regular follow-up by a physiotherapist seems to be a determining factor in adherence to this treatment.

While non-invasive ventilation (NIV) currently represents the first-line ventilatory strategy in patients exhibiting hypercapnic ARF, the operating principles and physiological effects of HFNO could be interesting and useful in the initial management of hypercapnic ARF and/or after extubation, particularly in acute exacerbations of chronic obstructive pulmonary disease. Under these conditions, HFNO could be used either alone continuously or in combination with NIV during breaks in spontaneous breathing, depending on the severity and etiology of the underlying hypercapnic ARF.

In the absence of oncogenic addiction, first-line immunotherapy, alone or in combination with chemotherapy, is the current standard of care. This review aims to synthesize the available data regarding the efficacy of immunotherapy in these patients, and to discuss the possibility of its being coordinated with local treatments such as radiotherapy. STATE OF THE ART: NSCLC patients with brain metastases appear to have survival benefits with immunotherapy similar to those of NSCLC patients without brain metastases. However, this finding is based on mainly prospective studies having included highly selected patients with pre-treated and stable brain metastases. Several retrospective studies and two prospective single-arm studies have confirmed the intracranial efficacy of immunotherapy, either alone or in combination with chemotherapy. PERSPECTIVES: The indications and optimal timing for cerebral radiotherapy remain subjects of debate. To date, there exists no randomized study assessing the addition of brain radiotherapy to first-line immunotherapy. That said, a recent meta-analysis showed increased intracerebral response when radiotherapy complemented immunotherapy. CONCLUSIONS: For NSCLC patients with brain metastases, the available data suggest a clear benefit of first-line immunotherapy, whether alone or combined with chemotherapy. However, most of these data are drawn from retrospective, non-randomized studies with small sample sizes.

This study aimed at assessing its medico-economic impact. METHODS: This was a retrospective database study of patients included in the PRADO BPCO between 2017 and 2019. Data were extracted from the National Health Data System. A control group was built using propensity score matching. Morbi-mortality and costs (national health insurance perspective) were measured during the year following hospitalization. RESULTS: While the proportion of patients with a care pathway complying with recommendations from the National Health Authority was higher in the PRADO group, there was no significant effect on mortality and 12-month rehospitalization. In the PRADO group, the rehospitalization rate was lower when the care pathway was optimal. Healthcare costs per patient were 670 € higher in the PRADO group. CONCLUSIONS: The PRADO COPD improves quality of care but without decreasing rehospitalizations and mortality, although rehospitalizations did decrease among PRADO group patients benefiting from an optimal care pathway.

These abnormalities are particularly common in Southeast Asia and French Polynesia. A 51-year-old Tahitian female non-smoker was diagnosed in 2018 with stage IV lung adenocarcinoma harboring a p.L858R EGFR mutation. She received gefitinib as first-line treatment. Due to locoregional progression and the presence of a resistance mutation (p.T790M of EFGR), she received osimertinib as second-line treatment, after which chemotherapy was proposed as 3rd-line treatment. An additional biopsy detected not only the previously known EGFR mutation, but also a BRAF p.V600E mutation. Following disease progression during chemotherapy, the patient received targeted therapies combining dabrafenib, trametinib and osimertinib. Due to a dissociated response after four months of treatment, a 5th line of paclitaxel bevacizumab was initiated. Subsequent to additional progression and given the ALK rearrangement shown on the re-biopsy, 6th-line treatment with alectinib was proposed. As the response was once again dissociated, a final line was proposed before stopping active treatments due to their toxicity and overall deterioration in the patient's state of health. This exceptional case is characterized by resistance to anti-EGFR through the successive and cumulative acquisition of two new oncogene addictions. The authors underline the importance of re-biopsy at each progression, leading (if at all feasible) to yet around round of targeted therapy.

It may present with hemoptysis, which can occur with or without antibiotic therapy and bronchial artery embolization may be required. We report here a case of pulmonary actinomycosis with imaging by thoracic CT, digital subtraction angiography, and pathological specimens.
