International audience; ObjectivesIn 2013, the French National Health Insurance set up a programme to help patients with heart failure to return home and stay there (PRADO). During a hospitalization for cardiac decompensation, the medical team decides on the inclusion of the patient in the programme based on eligibility criteria defined. The objective of this study was to identify the factors most associated with the inclusion of heart failure patients in the PRADO program.Materials and MethodsThis was a monocentric retrospective analytical stratified case-control study. It focused on the analysis of patient records hospitalized for cardiac decompensation between 01/01/2017 and 31/12/2018 in the cardiology department of the Centre Hospitalier de Troyes. For each patient included in the PRADO Heart Failure programme, one or two controls, not included in the PRADO Heart Failure programme were matched. The matching was exact without discounting. It was performed on the following criteria: age in 10-year increments, sex, main diagnosis of the stay, major category of diagnosis of the stay and its type (medical or surgical), the severity score of the Homogeneous Group of Patients of the stay and the Charlson score.ResultsA total of 40 patients included in PRADO Heart Failure were matched to 56 controls not included in PRADO Heart Failure. Patients with respiratory disease (3.77 [1.07 – 13.29]), as well as patients on renin-angiotensin system inhibitors (2.24 [1.61 – 5.31]) were more often included in the PRADO Heart Failure programme. The most frequent criteria for non-eligibility were the need to transfer the patient to a specialised institution and significant impairment of higher functions.ConclusionRespiratory comorbidity and renin-angiotensin system blocker treatment are the factors most associated with the inclusion of heart failure patients in the PRADO Heart Failure programme.; Objectifs : En 2013, l'Assurance Maladie a mis en place un "Programme d'aide au retour et maintien à domicile (PRADO)" pour les patients insuffisants cardiaques. Au cours d'une hospitalisation pour décompensation cardiaque, l’équipe médicale décide de l'inclusion du patient dans le programme en se basant sur des critères d’éligibilité définis par l'Assurance Maladie. L'objectif de cette étude était d'identifier les facteurs les plus associés à l'inclusion des patients insuffisants cardiaques dans le programme PRADO Insuffisance Cardiaque. Matériels et méthodes : Il s'agissait d'une étude cas-témoins rétrospective analytique monocentrique. Elle portait sur l'analyse de dossiers patients hospitalisés pour décompensation cardiaque entre le 01/01/2017 et le 31/12/2018 dans le service de cardiologie du Centre Hospitalier de Troyes. Pour chaque patient inclus dans le programme PRADO Insuffisance Cardiaque, un ou deux témoins, non inclus dans le programme PRADO Insuffisance Cardiaque ont été appariés. L'appariement était exact sans remise. Il a été réalisé sur les critères suivants : l’âge par tranches de 10 ans, le sexe, le diagnostic principal du séjour, la catégorie majeure de diagnostic du séjour et son type (médical ou chirurgical), le score de sévérité du Groupe homogène de malades du séjour et le score de Charlson. Résultats : Au total, 40 patients inclus dans le PRADO Insuffisance Cardiaque ont été appariés à 56 témoins non inclus dans le PRADO Insuffisance Cardiaque. Les patients présentant une pathologie respiratoire (3,77 [1,07 – 13,29]), ainsi que les patients sous inhibiteurs du système rénine-angiotensine (2,24 [1,61 – 5,31]) étaient plus souvent inclus dans le programme PRADO Insuffisance Cardiaque. Les critères de non-éligibilité les plus fréquents étaient la nécessité de transférer le patient vers une institution spécialisée et l'altération significative des fonctions supérieures.

International audience; During the dispensing process of medical orders (MOs), community pharmacists (CPs) can manage drug-related problems (DRPs) by performing pharmacist interventions (PIs). There is little evidence that the PI rate is higher with MOs from hospitals (MOHs) than ambulatory (MOAs) settings, and their impact on the patient and community pharmacy is unknown. The primary objective of this study was to compare the MOH and MOA PI rates. The secondary objective was to describe PIs and their clinical and organizational impacts on patient and community pharmacy workflow. A total of 120 CPs participated in a prospective study. Each CP included 10 MOH and 10 MOA between January and June 2020. DRP and PI description and clinical and organizational impacts between MOH and MOA were assessed and compared. We analyzed 2325 MOs. PIs were significantly more frequent in MOH than in MOA (9.7% versus 4.7%; p < 0.001). The most reported PI was the difficulty of contacting hospital prescribers (n = 45; 52.2%). MOHs were associated with a longer dispensing process time and a greater impact on patient pathway and community pharmacy workflow than MOAs. Lack of communication between hospital and primary care settings partly explains the results. Implementation of clinical pharmacy activities at patient discharge could alleviate these impacts.

International audience; In paediatric acute lymphoblastic leukaemia (ALL), focus has shifted towards preventing treatment-related complications, including venous thromboembolism, the cause of significant mortality and morbidity. To better understand thrombogenic mechanisms during induction treatment, we studied the number, origin and procoagulant activity of extracellular vesicles (EVs) and P-selectin level throughout the induction course in 24 paediatric patients. EVs were mainly of platelet origin. We observed a significant increase in EV number, in platelet EV number and P-selectin level throughout the induction course. There was a correlation between higher EV and platelet EV number, P-selectin level, higher platelet count and leucocyte count. We also observed a correlation between higher EV procoagulant activity and higher platelet count and leucocyte count and higher P-selectin level. Older age and T phenotype were associated with a higher EV procoagulant activity. Platelet EV generation may play a role in thrombogenic complications in ALL patients and could serve as a biomarker to identify patients with a high risk of thrombosis. As a marker of platelet activation, P-selectin may be another relevant marker with the advantage of being easier to analyse in clinical practice.

International audience; OBJECTIVES: To describe circumstances of the diagnosis and access to dermatological care for patients with cutaneous melanoma (CM) and to investigate factors associated with early detection. DESIGN: Retrospective population-based study of incident cases of invasive CM in 2004, using questionnaires to physicians and a survey of cancer registries and pathology laboratories. SETTING: Five regions in northeastern France. PATIENTS: Six hundred fifty-two patients who were referred to dermatologists by general practitioners (group 1) or by other specialists (group 2), who directly consulted a dermatologist for CM (group 3), or who were diagnosed as having CM during a prospective follow-up of nevi (group 4) or when consulting a dermatologist for other diseases (group 5). MAIN OUTCOME MEASURES: Characteristics of patients, tumors, and patients' residence in each group, including the geographical concentration of dermatologists. We performed multivariate analysis of these factors to determine association with Breslow thickness. RESULTS: Age, tumor location, Breslow thickness, ulceration, histological type, and geographical concentration of dermatologists significantly differed among groups. Patients consulting dermatologists directly formed the largest group (45.1%). Those referred by general practitioners (26.1%) were the oldest and had the highest frequency of thick (>3 mm), nodular, and/or ulcerated CM. Patients from groups 4 (8.4%) and 5 (14.1%) had the thinnest CMs. Ulcerated and/or thick tumors were absent in group 4. In multivariate analysis, histological types superficial spreading melanoma and lentigo maligna melanoma, younger age, high concentration of dermatologists, and detection by dermatologists were significantly associated with thinner CMs. CONCLUSION: Easy access of patients to dermatologists, information campaigns targeting elderly people, and education of general practitioners are complementary approaches to improving early detection.

Background Previous studies showed that at the individual level, positron emission tomography (PET) has some benefits for patients and physicians in terms of cancer management and staging. We aimed to describe the benefits of (PET) in the management of solitary pulmonary nodules (SPNs) in a population level, in terms of the number of diagnostic and invasive tests performed, time to diagnosis and factors determining PET utilization. Methods In an observational study, we examined reports of computed tomography (CT) performed and mentioning "spherical lesion", "nodule" or synonymous terms. We found 11,515 reports in a before-PET period, 2002–2003, and 20,075 in an after-PET period, 2004–2005. Patients were followed through their physician, who was responsible for diagnostic management. Results We had complete data for 112 patients (73.7%) with new cases of SPN in the before-PET period and 250 (81.4%) in the after-PET period. Patients did not differ in mean age (64.9 vs. 64.8 years). The before-PET patients underwent a mean of 4 tests as compared with 3 tests for the after-PET patients (p = 0.08). Patients in the before-PET period had to wait 41.4 days, on average, before receiving a diagnosis as compared with 24.0 days, on average, for patients in the after-PET period who did not undergo PET (p < 0.001). In the after-PET period, 11% of patients underwent PET during the diagnostic process. A spiculated nodule was more likely to determine prescription for PET (p < 0.001). Multivariate analysis revealed that patients in both periods underwent fewer tests when PET was prescribed by general practitioners (p < 0.001) and if the nodule was not spiculated (p < 0.001). The proportion of unnecessary invasive approaches prescribed (47% vs. 49%) did not differ between the groups. Conclusion In our study, 1 year after the availability of PET, the technology was not the first choice for diagnostic management of SPN. Even though we observed a tendency for reduced number of tests and mean time to diagnosis with PET, these phenomena did not fully relate to PET availability in health communities. In addition, the availability of PET in the management of SPN diagnosis did not reduce the overall rate of unnecessary invasive approaches.

International audience; AGEs (advanced glycation end-products) accumulate in collagen molecules during uraemia and diabetes, two diseases associated with high susceptibility to bacterial infection. Because neutrophils bind to collagen during their locomotion in extravascular tissue towards the infected area we investigated whether glycoxidation of collagen (AGE-collagen) alters neutrophil migration. Type I collagen extracted from rat tail tendons was used for in vitro glycoxidation (AGE-collagen). Neutrophils were obtained from peripheral blood of healthy adult volunteers and were used for the in vitro study of adhesion and migration on AGE- or control collagen. Glycoxidation of collagen increased adhesion of neutrophils to collagen surfaces. Neutrophil adhesion to AGE-collagen was inhibited by a rabbit anti-RAGE (receptor for AGEs) antibody and by PI3K (phosphoinositide 3-kinase) inhibitors. No effect was observed with ERK (extracellular-signal-regulated kinase) or p38 MAPK (mitogen-activated protein kinase) inhibitors. AGE-collagen was able to: (i) induce PI3K activation in neutrophils, and (ii) inhibit chemotaxis and chemokinesis of chemoattractant-stimulated neutrophils. Finally, we found that blocking RAGE with anti-RAGE antibodies or inhibiting PI3K with PI3K inhibitors restored fMLP (N-formylmethionyl-leucyl-phenylalanine)-induced neutrophil migration on AGE-collagen. These results show that RAGE and PI3K modulate adhesion and migration rate of neutrophils on AGE-collagen. Modulation of adhesiveness may account for the change in neutrophil migration rate on AGE-collagen. As neutrophils rely on their ability to move to perform their function as the first line of defence against bacterial invasion, glycoxidation of collagen may participate in the suppression of normal host defence in patients with diabetes and uraemia.

International audience; OBJECTIVE: To describe current management of cutaneous melanoma (CM) and identify factors accounting for disparities. DESIGN: Retrospective population-based study using survey of cancer registries and pathology laboratories, and questionnaires to physicians. SETTING: Five regions covering 19.2% of the French territory and including 8.2 million inhabitants. PATIENTS: Incident cases of patients with stage I to stage II (hereinafter, stage I-II) tumors staged according to the American Joint Committee on Cancer Staging guidelines and nodal stage III CM in 2004. MAIN OUTCOME MEASURES: Modalities of diagnosis and excision, surgical margins, sentinel lymph node biopsy, adjuvant therapies and surveillance procedures, and their variations according to age, sex, residence, location of primary CM, Breslow thickness, type of physicians, modalities of decisions, and health care patterns. RESULTS: Clinical stage I-II CMs (n = 710 cases) slightly predominated in females (53%), with a lower mean Breslow thickness (1.4 mm) than in males (1.9 mm). Initial excisions were most often performed by private dermatologists and wide excisions by surgeons. Narrow margins (8%) were associated with advanced age, higher Breslow thickness, and head location. Sentinel lymph node biopsy was performed in 34% of CMs thicker than 1.0 mm, depending on geographical regions, distance from reference centers, and health care patterns. Adjuvant therapies (mainly low-dose interferon) were proposed in 53% of thick CMs (>1.5 mm), depending on the patient's age and geographical region. In contrast with French recommendations, surveillance procedures frequently included systematic medical imaging. Stage III nodal CMs (n = 89 cases) predominated in males (62%). After lymphadenectomy, adjuvant therapies (including high-dose interferon in 32% of cases and chemotherapies in 24% of cases) were proposed in 68% of cases, depending on the patient's age and geographical region. A complete 1-year high-dose interferon regimen was administered in less than 10% of cases. CONCLUSION: Large disparities still exist in the management of CM in France, depending to a greater extent on medical and geographical environment than on the characteristics of either patients or tumors.

International audience; Usual imaging after endovascular aneurysm repair (EVAR) of abdominal aortic aneurysm (AAA) consists of AAA diameter monitoring and endoleak detection. Among additional predictor parameters previously proposed to help clinicians in better identifying subgroups of AAA still at risk of rupture, AAA wall motion after EVAR has been studied, but its value was not clearly established. Tissue Doppler imaging (TDI) is an ultrasonographic modality which allows wall motion measurements along an arterial segment. The aim of the current study was to analyze AAA wall motion with TDI before and after EVAR and to describe its evolution in patients with more than 1 month of follow-up. Twenty-five consecutive patients undergoing EVAR between February 2005 and June 2007 gave informed consent to be prospectively investigated with the TDI system before EVAR and at each visit during follow-up. The mean (SD) follow-up was 13.7 (9.7) months. Maximum mean segmental dilation (MMSD), segmental compliance, dilation at maximum diameter, pressure strain elastic modulus (Ep), and stiffness were compared between three periods (before stenting, before discharge, and at last follow-up), and their relation with AAA diameter was analyzed. A significant decrease in AAA compliance was immediately observed after successful EVAR and remained stable during later follow-up. On the other hand, AAA diameter progressively decreased along time and was statistically lower at the last control compared to the initial value. MMSD, segmental compliance, and dilation at maximum diameter were positively related to AAA diameter. This means that the larger the AAA diameter after stenting, the higher the value for these parameters can be expected. On the contrary, percentage of AAA diameter decrease and percentage of MMSD decrease were not related after successful EVAR. There was no parallelism between loss in compliance and diameter decrease along time, and there is not a unique pattern of AAA diameter and compliance evolution after EVAR. Even if comparison between patients without and with endoleak was weak due to the small sample of the latter group (five patients with endoleak), compliance tended to be greater in case of endoleak. AAA wall motion after successful EVAR reflects complex interactions between all the components of the stented aneurysm which evolve over time, including true compliance of the aneurysm wall itself; intra-aneurysm sac pressure with possible different effects for peak, mean, and pulse pressures; remodeling of the thrombus; stiffness characteristics of the graft; and systemic pressure. Combining simultaneous MMSD records with actual intrasaccular pressure measurements in patients with and without endoleak would improve our understanding of the clinical pulsatility mechanism within AAA after EVAR.
