Abstract
BACKGROUND Small cell lung cancer (SCLC) has a tendency towards recurrence and limited survival. Standard-of-care in 1st-line is platinum-etoposide chemotherapy plus atezolizumab or durvalumab,based on landmarkclinical trials. METHODS IFCT-1905 CLINATEZO is a nationwide, non-interventional, retrospectivestudy of patients with extensive-SCLC receivingatezolizumab plus chemotherapy as part of French Early Access Program. Objectives were to analyse effectiveness,safetyand subsequent treatments. RESULTS The population analyzed included 518 patients who received atezolizumabin 65 participating centers. There were 66.2% male,mean age was 65.7 years; 89.1% had a performance status (PS) 0/1 and 26.6% brain metastases. Almost all(95.9%) were smokers. Fifty-five (10.6%) received at least 1 previous treatment. Median number of atezolizumab injections was 7.0 (range [1.0-48.0]) for a median duration of 4.9 months (95% CI 4.5-5.1). Atezolizumab was continued beyond progression in 122 patients (23.6%) for a median duration of 1.9 months (95% CI: [1.4-2.3]). Best objective response was complete and partialin 19 (3.9%) and 378 (77.1%)patients. Stable diseasewas observed in 50 patients (10.2%). Median follow-up was30.8 months (95% CI: [29.9-31.5]). Median overall survival (OS), 12-, 24-month OS rates were 11.3 months (95% CI: [10.1-12.4]), 46.7% (95% CI [42.3-50.9]) and 21.2% (95% CI [17.7-24.8]). Median real-world progression-free survival, 6-, 12-month rates were 5.2 months (95% CI [5.0-5.4]), 37.5% (95% CI [33.3-41.7]) and 15.2% (95% CI [12.2-18.6]). For patients with PS 0/1, median OS was 12.2 months (95% CI [11.0-13.5]). For patients with previous treatment, median OS was 14.9 months (95% CI [10.1-21.5]). Three-hundred-and-twenty-six patients(66.4%) received subsequent treatment and27 (5.2%) were still underatezolizumabat date of last news. CONCLUSIONS IFCT-1905 CLINATEZO shows reproductibility, in real-life,ofIMpower-133survival outcomes, possibly attributed to selection of patients fit for this regimen, adoption of pragmatic approaches,including concurrent radiotherapy and treatment beyond progression.

Abstract
INTRODUCTION Lung cancer is the leading cause of cancer-related death in France and has a 5-year survival rate of 20%. Recent prospective randomized controlled trials revealed that lung cancer-specific mortality decreased in patients who underwent screening using low-dose chest computed tomography (low-dose CT). The DEP KP80 pilot study conducted in 2016 showed that an organized lung cancer screening campaign involving general practitioners was feasible. MATERIAL AND METHOD We conducted a descriptive observational study of screening practices by sending a self-reported questionnaire to 1013 general practitioners practicing in the Hauts-de-France region. Our study's primary aim was to investigate the knowledge and practices of general practitioners in the Hauts-de-France region of France regarding lung cancer screening using low-dose CT. The secondary endpoint was to compare practices between general practitioners in the Somme department who had experience of experimental screening and their colleagues in the rest of the region. RESULTS The response rate was 18.8% (190 completed questionnaires). Even though 69.5% of the physicians were unaware of the potential benefits of organized low-dose CT screening for lung cancer, 76% proposed screening tests for individual patients. Despite its proven ineffectiveness, chest radiography was still the most widely recommended screening modality. Half of the physicians stated that they had already prescribed chest CT to screen for lung cancer. Additionally, only 36.3% proposed chest CT screening for patients aged over 50 years with a history of more than 30 pack-years. The physicians working in the Somme department (61% had participated in the DEP KP80 pilot study) were more aware of low-dose CT as a screening modality, and offered it significantly more than their colleagues in the other departments (61.1% vs 13.4% p<0.01). All the physicians were in favor of an organized screening program. CONCLUSION More than a third of general practitioners in the Hauts-de-France region offered for lung cancer screening using chest CT, although only 18% specified low-dose CT. Before an organized screening program can be set up, good practice guidelines must be made available about lung cancer screening.

Abstract
INTRODUCTION Tracheal tumors are rare, they are most often malignant and can manifest themselves by a non-specific respiratory symptomatology with progressively increasing dyspnea orienting in the first place towards a COPD or even an asthma. Among them, tracheal lipoma is exceptional. Its management is based on removal by rigid bronchoscopy. OBSERVATION We report the case of a 73-year-old male patient who presented with non-specific dyspnea that progressively worsened over several months. The EFR showed a flattening of the flow-volume curves, the CT scan showed an anterolateral oval tracheal tumor with fatty density, the bronchial endoscopy showed a tumor lesion with stenosis of about 90% of the airway. Management consisted of a rigid bronchoscopy to delete obtruction with biopsies. Anatomopathology concluded to a tracheal lipoma. CONCLUSION Progressively worsening dyspnea, especially if there are signs of inspiratory dyspnea, required a systematic bronchial endoscopy to avoid the possibility of a tracheal tumor.

Abstract
INTRODUCTION Over the last few years, lung cancer screening by low-dose CT scan has demonstrated a decrease in lung cancer mortality. While this method has been in use since 2013 in the United States of America, no European country has yet implemented a systematic screening program. We hereby report the results from the second round of screening from a French cohort study. PATIENTS AND METHODS DEP KP80 is a prospective study evaluating lung cancer screening by means of three low-dose computer tomography (CT) scans at 1-year intervals in 1,307 participants, aged 55 to 74 years old, all smokers or former smokers, having quit within the last 15 years, with over 30 pack years. The results of the first round demonstrated it was possible to conduct effective screening in real-life situations. RESULTS Participation was lower in this second round than in the first (35.3% vs. 73.1%, P < .001). The rate of negative results was significantly higher and that of undetermined results lower than those produced in the first round. Overall, 75% of cancers revealed were Stage 1 and 87.5% benefitted from surgical treatment. The incidence of cancer in the second round was 2.43%. CONCLUSION As with the first round, the results of this second round confirm the feasibility and efficacy of lung cancer screening. The lower participation rate for this second round is proof of the need to improve awareness among participants and healthcare professionals of the relevance of committing to an annual screening program.

Abstract
INTRODUCTION A study on lung cancer screening using low-dose computed tomography (DEP KP80) was conducted in the Somme department in northern France between May 2016 and December 2018. We conducted a cross-sectional survey of family physicians in that department to identify potential predictive factors for their participation in this pilot study. METHODS A survey questionnaire was sent to the 545 general practitioners (GPs) of the Somme department. This survey rendered it possible to identify the investigators who were active in the DEP KP80 study. The questionnaire's content was focused on the socio-demographic conditions of GPs, their professional practices, and their medical practice situations. RESULTS The response rate was 38% (206 completed questionnaires). Active investigators in DEP KP80 accounted for 55% (n=113) of the GPs surveyed, and non-investigators for 45% (n=93). Age, gender, or medical practice situation were not related to the active GPs' participation in DEP KP80. A multivariate analysis revealed that two factors were correlated with active participation in organized screening: (1) prescription of nicotine replacement therapy; (2) smoking history of the GP. CONCLUSIONS Securing the active involvement of family physicians and of the French regional cancer screening coordination centers seems essential for the future organization of lung cancer screening on a regional or national level. Our results demonstrate that incorporating smoking cessation support structures into the program would maximize the mechanism's potential.

Abstract
RATIONALE This feasibility trial proposes to set up in the department of the Somme an annual screening for lung cancer with low-dose thoracic CT. It responds to the first objective of the third cancer plan and follows the publication of the results of the National Lung Screening Trial in 2011. METHODS The method of this study is to use the existing networks among and between healthcare professionals and the departmental cancer screening structure. The inclusion criteria will be those of the National Lung Screening Trial. Screening will be proposed by treating physicians and chest physicians. The CT-scan will be performed in radiological centers that adhere to the good practice charter for low radiation scanning. A copy of CT results will be sent to the departmental structure of cancer screening (ADEMA80) which will ensure traceability and will perform statistical analysis. The study received funding from the Agence régionale de santé de la Picardie and la ligue contre le cancer. EXPECTED RESULTS The primary endpoints of this screening will be the number of cancers diagnosed and the survival of the patients. The follow-up of positive examinations, delays in management and the level of participation will also be assessed.

Abstract
Thoracic endometriosis is a rare disease, which presents in women at a mean age of 35 years, later than for pelvic endometriosis. There are no known predisposing factors for the condition and its pathogenesis is not yet clearly established. The symptoms always appear in connection with the periods of the person affected by the condition, occurring within 24-48 h after the start of menstruation. Catamenial pneumothorax is the most common clinical entity. It is associated with pelvic endometriosis in 30-50% of cases. Thoracoscopy, preferably performed during menstruation, allows full inspection of the diaphragm and the pleural cavity for defects in the diaphragm, endometrial nodules and bullae. The level of CA 125 is often elevated but this is not a reliable or specific marker. Medical treatment is aimed at blocking the action of estrogen on the endometrium and ectopic endometrial implants. GnRH analogues or danazol are the preferred treatments. Surgery to repair and strengthen the diaphragm and/or resect nodules or bullae also has a role, supplemented by pleurodesis to prevent further pneumothorax or effusions. The main risk is recurrence, and thus the current usual practice is to combine surgery, immediately followed by hormone therapy focusing on GnRH analogues.

Abstract
INTRODUCTION Pulmonary epithelioid haemangioendothelioma (PEH) is a rare vascular tumour of intermediate malignancy that predominantly affects women. CLINICAL CASE REPORTS We report three cases of PEH. Though all three diagnoses were confirmed by surgical biopsy, it is notable that, in one case, a tracheal biopsy by flexible bronchoscopy was contributory. Two patients had undergone positron emission tomography, which showed the lesions to be well established. The three cases show that the evolution of this pathology can be very varied. In the first case, the disease was multifocal and needed to be treated with several pulmonary resections. In the second case no recurrence has been observed after surgery; in the third case the patient died following a haemothorax. CONCLUSION The discovery of a PEH is usually fortuitous. The diagnosis is confirmed by immuno-chemical analysis of a lung biopsy. No standard treatment has been validated and no treatment is necessary if the disease is asymptomatic. If there is only one nodule, surgery is the treatment of choice. The prognosis is variable. Usually the evolution is slow except when the disease is complicated by haemoptysis, pleural effusion, haemothorax, mediastinal lymphadenopathy or hepatic spread.

Abstract
Nitrate transporters are important for nitrogen acquisition by plants and in algae some require two gene products, NRT2 and NAR2, for function. The NRT2 family was already described and the recent identification of a family of the NAR2-type genes in higher plants showed that there was a homologue in Arabidopsis, AtNAR2.1. Using heterologous expression in yeast and oocytes we showed that the two Arabidopsis AtNRT2.1 and AtNAR2.1 proteins interacted to give a functional high affinity nitrate transport system (HATS). The gene knock out mutant atnar2.1-1 is deficient specifically for HATS activity and the resulting growth phenotype on low nitrate concentration is more severe than for the atnrt2.1-1 knock out mutant. Physiological characterisation of the plant N status and gene expression revealed a pattern that was characteristic of severe nitrogen deficiency. Consistent with the down regulation of AtNRT2.1 expression, the atnar2.1-1 plants also displayed the same phenotype as atnrt2.1 mutants in lateral root (LR) response to low nitrate supply. Using atnar2.1-1 plants constitutively expressing the NpNRT2.1 gene, we now show a specific role for AtNAR2.1 in LR response to low nitrate supply. AtNAR2.1 is also involved in the repression of LR initiation in response to high ratios of sucrose to nitrogen in the medium. Therefore the two component system itself is likely to be involved in the signaling pathway integrating nutritional cues for LR architecture regulation. Using a green fluorescent protein-NRT2.1 protein fusion we show the essential role of AtNAR2.1 for the presence of AtNRT2.1 to the plasma membrane.

Abstract
The identification of a family of NAR2-type genes in higher plants showed that there was a homolog in Arabidopsis (Arabidopsis thaliana), AtNAR2.1. These genes encode part of a two-component nitrate high-affinity transport system (HATS). As the Arabidopsis NRT2 gene family of nitrate transporters has been characterized, we tested the idea that AtNAR2.1 and AtNRT2.1 are partners in a two-component HATS. Results using the yeast split-ubiquitin system and Xenopus oocyte expression showed that the two proteins interacted to give a functional HATS. The growth and nitrogen (N) physiology of two Arabidopsis gene knockout mutants, atnrt2.1-1 and atnar2.1-1, one for each partner protein, were compared. Both types of plants had lost HATS activity at 0.2 mm nitrate, but the effect was more severe in atnar2.1-1 plants. The relationship between plant N status and nitrate transporter expression revealed a pattern that was characteristic of N deficiency that was again stronger in atnar2.1-1. Plants resulting from a cross between both mutants (atnrt2.1-1 x atnar2.1-1) showed a phenotype like that of the atnar2.1-1 mutant when grown in 0.5 mm nitrate. Lateral root assays also revealed growth differences between the two mutants, confirming that atnar2.1-1 had a stronger phenotype. To show that the impaired HATS did not result from the decreased expression of AtNRT2.1, we tested if constitutive root expression of a tobacco (Nicotiana plumbaginifolia) gene, NpNRT2.1, previously been shown to complement atnrt2.1-1, can restore HATS to the atnar2.1-1 mutant. These plants did not recover wild-type nitrate HATS. Taken together, these results show that AtNAR2.1 is essential for HATS of nitrate in Arabidopsis.

Abstract
The PII signal transducing protein is involved in carbon/nitrogen (C/N) sensing in bacteria and cyanobacteria. In higher plants the function of the PII homolog GLB1 is not known. GLB1 transcripts were found in all plant organs tested, while in Arabidopsis leaves GLB1 expression and PII protein levels were not significantly affected by either the day/night cycle or N-nutrition. Its putative regulatory role in plants has been studied by analysing Arabidopsis thaliana T-DNA insertion lines in the GLB1 gene. These PII mutants showed an 80% (PIIV1 mutant) and 100% (PIIS2 mutant) reduced AtGLB1 transcript level and no detectable PII protein. They did not display an altered growth or developmental phenotype when grown under non-limiting conditions suggesting that the PII protein does not play a crucial role in plants. However, in vitro grown PII mutants did show a higher sensitivity to nitrite (NO (2) (-) ) compared to the wild-type plants. This observation is reminiscent of the role of PII in the regulation of NO (2) (-) metabolism in cyanobacteria. Furthermore, when grown hydroponically, the PII mutants displayed a slight increase in carbohydrate (starch and sugars) levels in response to N starvation and a slight decrease in the levels of ammonium (NH (4) (+) ) and amino acids (mainly Gln) in response to NH (4) (+) resupply. Although the phenotypic changes are rather small in the mutant lines, these data support the hypothesis of a subtle involvement of the PII protein in the regulation of some steps of primary C and N metabolism.

Abstract
INTRODUCTION Respiratory rehabilitation is a multidisciplinary approach enabling personalized management adapted for each patient's handicap. METHOD Our ambulatory program includes twenty sessions per week (four half-days/week) for respiratory training at the ventilatory threshold, respiratory physical therapy, and health education. One hundred COPD patients participated in this retrospective study: mean age 62.1 +/- 9.6 years; FEV1: 1.51 +/- 0.66 (53 +/- 22% of theoretical). RESULTS At the ventilatory threshold, there was a significant 9% gain in oxygen uptake and a 31% gain in power. At maximal exercise, there was a 6% improvement in oxygen uptake, 21% gain in power, and 7% gain in tidal volume (p<0.05). Walking distance improved 15% (+ 61 m). Quality of life was also improved significantly, with loss of 8 points on the Saint-George's Hospital respiratory questionnaire. CONCLUSION This study demonstrates the beneficial effect of respiratory rehabilitation in terms of improved tolerance to exercise and improved quality of life for COPD patients.

Abstract
The intrinsic positive-end-expiratory pressure (PEEPi) increases the inspiratory load, the cost of breathing and thus oxygen consumption (V(O2)). It has been shown that applying an extrinsic positive-end-expiratory pressure (PEEPe) reduces the inspiratory threshold load but the optimal PEEPe level is still in debate. We hypothesize that the best level of PEEPe could induce a decrease in V(O2) by reducing the V(O2) demands from PEEPi. Nine mechanically ventilated COPD patients were included. The level of PEEPe was determined in accordance with the static PEEPi. V(O2) was measured using an automatic gas analyser during synchronized intermittent mandatory ventilation (SIMV): without PEEPe, with a PEEPe equal to 50% of static PEEPi and with a PEEPe equal to 100% of static PEEPi. Static PEEPi appeared to be significantly correlated with the degree of airflow obstruction (FEV1) (P<0.05). Applying a PEEPe equal to static PEEPi resulted in a significant decrease in V(O2) (P<0.05) whereas the change in V(O2) proved to be unpredictable for a PEEPe level of 50% of static PEEPi. In conclusion, V(O2) decreases progressively when increasing PEEPe up to a level equal to 100% of static PEEPi. Thus, in mechanically ventilated COPD patients with a FEV1 < or = 1000 ml, applying a PEEPe of 5 cmH2O should be recommended.

Abstract
Genomic projects heavily depend on genome annotations and are limited by the current deficiencies in the published predictions of gene structure and function. It follows that, improved annotation will allow better data mining of genomes, and more secure planning and design of experiments. The purpose of the GeneFarm project is to obtain homogeneous, reliable, documented and traceable annotations for Arabidopsis nuclear genes and gene products, and to enter them into an added-value database. This re-annotation project is being performed exhaustively on every member of each gene family. Performing a family-wide annotation makes the task easier and more efficient than a gene-by-gene approach since many features obtained for one gene can be extrapolated to some or all the other genes of a family. A complete annotation procedure based on the most efficient prediction tools available is being used by 16 partner laboratories, each contributing annotated families from its field of expertise. A database, named GeneFarm, and an associated user-friendly interface to query the annotations have been developed. More than 3000 genes distributed over 300 families have been annotated and are available at http://genoplante-info.infobiogen.fr/Genefarm/. Furthermore, collaboration with the Swiss Institute of Bioinformatics is underway to integrate the GeneFarm data into the protein knowledgebase Swiss-Prot.

Abstract
INTRODUCTION Aortobronchial fistulas are uncommon but generally fatal if not treated surgically. Haemoptysis is the main symptom of this pathology. STATES OF ART AND PERSPECTIVES: Aortobronchial fistulas occur most commonly in patients with thoracic aneurysms (atherosclerosis, mycotic, aortic surgery's complication...). Main investigation is CT angiography with 2 D and 3 D reconstructions. CONCLUSION Endovascular exclusion can be efficient treatment option.

Abstract
The effect of supplying either nitrate or ammonium on nitrate reductase activity (NRA) was investigated in Brassica napus seedlings. In roots, nitrate reductase activity (NRA) increased as a function of nitrate content in tissues and decreased when ammonium was the sole nitrogen source. Conversely, in the shoots (comprising the cotyledons and hypocotyl), NRA was shown to be independent of nitrate content. Moreover, when ammonium was supplied as the sole nitrogen source, NRA in the shoots was surprisingly higher than under nitrate supply and increased as a function of the tissue ammonium content. Under 15 mM of exogenous ammonium, the NRA was up to 2.5-fold higher than under nitrate supply after 6 d of culture. The NR mRNA accumulation under ammonium nutrition was 2-fold higher than under nitrate supply. The activation state of NR in shoots was especially high compared with roots: from nearly 80% under nitrate supply it reached 94% under ammonium. This high NR activation state under ammonium supply could be the consequence of the slight acidification observed in the shoot tissue. The effect of ammonium on NRA was only observed in cotyledons and when more than 3 mM ammonium was supplied. No such NRA increase was evident in the roots or in foliar discs. Addition of 1 mM nitrate under ammonium nutrition halved NRA and decreased the ammonium content in shoots. Thus, this unusual NRA was restricted to seedling cotyledons when nitrate was lacking in the nitrogen source.

Abstract
INTRODUCTION Pulmonary diseases during the course of generalised amyloidosis are principally represented by tracheobronchial involvement and diffuse parenchymal localizations. CASE REPORT The authors report the case of a 66-year-old woman presenting with pleural amyloidosis in the context of generalised amyloidosis. Thoracoscopy performed in the investigation of recurrent transudative pleural effusions found evidence of an inflamed parietal pleura with areas of calcification. Pleural biopsies confirmed amyloid infiltration pleural ossification. Talc pleurodesis was performed. CONCLUSIONS The authors' conclusion is that, meeting an unexplained pleural effusion even transudative during the course of a generalised amyloidosis, the thoracoscopy is the diagnosis key test as it allows moreover a pleural pleurodesis to be performed.

Abstract
OBJECTIVE To determine the effects of a pressure support ventilation (PSV) of 6 cm H(2)O during spontaneous breathing on oxygen consumption of the respiratory muscles (VO(2) resp), gas exchange, respiratory rate, tidal volume and to determine if these low levels of PSV can reduce or cancel the increase in work of breathing induced by the resistances of the endotracheal tube and the circuit of the respirator. PATIENTS AND METHODS Prospective study. Twenty intubated patients were studied. The VO(2) resp was assessed by measurements of inspired and expired concentrations of oxygen (O(2)) and carbon dioxide (CO(2)) in patients during controlled ventilation and spontaneous breathing. Gas exchange, respiratory rate, minute ventilation, tidal volume and VO(2) resp were collected during spontaneous breathing with a PSV level of 6 cm H(2)O and without PSV. SETTING Respiratory Intensive Care Unit, Amiens, University Hospital 80054 Amiens. RESULTS A PSV level of 6 cm H(2)O significantly increased the spontaneous tidal volume (+12%) without any modification in respiratory rate, minute ventilation, tidal volume and gas exchange. No significant improvement in VO(2) resp was found when a PSV level of 6 cm H(2)O was added. CONCLUSION Despite a significant increase in spontaneous tidal volume, adding a PSV level of 6 cm H(2)O did not improve VO(2) resp. Thus, low level of PSV did not reduce the increased work of breathing induced by the resistances of the ventilator tubing and the endotracheal tube.

Abstract
The authors report a case of tuberculosis of the breast in a patient aged 71. The case described is an example of a rare form of extra pulmonary tuberculosis whose diagnosis can pose problems. In view of the recent increase in the incidence of tuberculosis in certain developed countries and the growth in the proportion of cases of extra pulmonary tuberculosis especially in HIV sero-positive individuals an observation such as this is useful in that it recalls for clinicians the fact that tuberculosis may present in very unusual forms which are easily forgotten.

Abstract
Sarcoidosis is a diffuse granulomatosis predominately with mediastino-pulmonary localizations. A wide range of extrathoracic localizations can also occur and when they are the initial manifestation, may lead to misdiagnosis. We observed a rare case of peritoneal sarcoidosis revealed by a surgical emergency.
