Influence of Perioperative Factors on Patency After Endovascular and Hybrid Treatments of TASC II D Aortoiliac Occlusive Lesions.

BACKGROUND: Treatment of Trans-Atlantic Inter-Society Consensus (TASC) II D aortoiliac occlusive disease (AIOD D) remains a controversial topic. Although current recommendations support conventional surgical treatment, several recent studies have reported promising results with endovascular and hybrid strategies. The purpose of this work was to describe the outcomes of endovascular and hybrid management of AIOD D and to investigate the influence of perioperative factors on patency. METHODS: This was a retrospective single-center study covering the period from 2016 to 2021. The primary end point was primary patency at 12 months. Secondary endpoints included technical success rate, 30-day mortality, early major complication rate, primary assisted and secondary patency at 12 months, and primary patency at 24 months. After descriptive statistical analysis, a survival analysis was conducted using the Kaplan-Meier method. Eighteen perioperative factors potentially associated with primary patency were studied by univariate and multivariate analysis adjusted by a Cox regression model. RESULTS: In all, 82 patients (112 limbs) had undergone an attempt at endovascular (n = 55, 67%) or hybrid (n = 27, 33%) treatment for AIOD D over the study period. The technical success rate was 99%. The 30-day mortality rate was 3%. The early major complication rate was 11%. The primary patency rates at 12 and 24 months were 87.9% [80.3; 96.3] and 77% [66.3; 89.3], respectively. The primary assisted and secondary patency rates at 12 months were 92.6% [86.3; 99.2] and 96% [91.4; 100]. Among the perioperative factors studied, the heavily calcified nature of the target lesions was the only variable significantly associated with primary patency loss in the multivariate analysis (P = 0.021). CONCLUSION: Although the results of endovascular and hybrid treatment of AOID D are acceptable, future studies should focus on improving patency rates in heavily calcified lesions. Specific tools of endovascular preparation (intravascular lithotripsy, atherectomy) may represent interesting ways of research.

An unusual outbreak of parvovirus B19 infections, France, 2023 to 2024.

From April 2023 to May 2024, an unusual epidemic of parvovirus B19 (B19V) infections occurred in France. The number of B19V IgM-positive serologies was four times higher than in the previous epidemic in 2019. Clinical data from emergency networks corroborated this observation. Morbidity and mortality consequences were observed in children through all data sources. In adults, the increase was only observed in laboratory-confirmed data. Physicians and decisionmakers should be informed in order to better prevent, diagnose and manage at-risk patients.

Antineoplastic chemotherapy and immunosuppression in liver transplant recipients: Squaring the circle?

BACKGROUND: Malignancies are a major cause of late death after liver transplantation (LT). In LT recipients presenting a malignancy, antineoplastic chemotherapy is central part of the therapeutic arsenal, but management of both immunosuppressive and antineoplastic chemotherapy can be very challenging. The aim of the present retrospective study was to describe a recent single center cohort of LT recipients treated with antineoplastic cytotoxic chemotherapy. METHODS: All LT recipients who received antineoplastic chemotherapy in our center between 2005 and 2021 were included. RESULTS: The study population included 72 antineoplastic chemotherapy courses in 69 patients. There was a majority of men (81.9%); median age at LT was 54.9 (range 1-68) and was 63.0 (18-79) at the diagnosis of malignancy. Lung carcinomas (23.6%), head and neck carcinomas (20.8%), lymphomas (16.7%), and recurrent hepatocellular carcinoma (HCC) (8.3%) were the most frequent malignancies. Neoadjuvant (30.6%), adjuvant (12.5%) or palliative (54.2%) chemotherapy was performed. Immunosuppressive regimen was modified from a calcineurin inhibitor (CNI)-based to an everolimus-based regimen (63.5% of CNI discontinuation). Median survival after diagnosis of malignancy was 22.5 months and 5-year survival was 30.1%. Chemotherapy regimen was considered optimal in 81.9% of the cases. Multivariate analysis disclosed that non-PTLD N+ stage malignancy (HR = 5.52 95%CI [1.40;21.69], p = .014), non-PTLD M+ stage malignancy (HR = 10.55 95%CI [3.20;34.73], p = .0001), and suboptimal chemotherapy (HR = 2.73 95%CI [1.34;5.56], p = .005) were significantly associated with poorer prognosis. No rejection episode occurred during chemotherapy. CONCLUSIONS: The present study is the first one focused on antineoplastic chemotherapy in LT recipients. Our results suggest that immunosuppressive drugs and antineoplastic chemotherapy can be managed satisfactorily in most cases but this needs confirmation from larger cohorts.

Epidemiological surveillance and infectious disease outbreaks during mass international summertime sports gatherings: A narrative review.

The XXXIIIrd Paris Summer Olympics followed by the XVIIth Paralympics Games will take place in France, predominantly in and around Paris, from July 26 to September 8, 2024. Public health stakeholders and decision-makers are called upon to set up or strengthen surveillance systems in areas hosting Olympic or Paralympic Games (OPGs) or large-scale international competitions, the objective being to detect and manage outbreaks should they occur during that period. We undertook a narrative review of the literature so as to identify major reported infectious disease outbreaks linked with or during OPGs / international sporting events during warm seasons. Our review found that since 1992, Summer Olympic and Paralympic games and international football competitions have been associated with sporadic cases of infectious diseases, principally respiratory, gastrointestinal/foodborne, but not with any major communicable or other infectious disease outbreak. Communicable disease risks should be assessed for the population taken as a whole, an integrated ecosystem with several population compartments potentially exchanging pathogens among one another. Although the Games afford an opportunity to federate or invent new surveillance systems to fill a gap, surveillance should be based on existing medical and laboratory systems, proven tools reinforced with the necessary human and financial resources. The performance of the public health surveillance system is ultimately predicated on trust on the part of participating clinicians, policymakers and international partners.

Pulmonary function test results are correlated with 6-minute walk distance, distance-saturation product, and 6-minute walk work in patients with lymphangioleiomyomatosis.

BACKGROUND AND OBJECTIVE: Lymphangioleiomyomatosis (LAM) is a rare multicystic lung disease. Although a correlation between pulmonary function test (PFT) results and exercise capacity appears probable, it has not yet been demonstrated. The aim of this study was to assess whether PFT results correlate with 6-minute walk test (6MWT) results in patients with LAM. METHODS: We conducted a retrospective study of all patients with a diagnosis of LAM followed in a French reference centre over a 13-year period. PFT and 6MWT data were collected. Distance-saturation product (DSP) and 6-minute walk work (6MWORK) were calculated. RESULTS: A total of 62 patients were included. Their median forced expiratory volume in 1 s (FEV1) was 82.7 % predicted and their median forced vital capacity (FVC) was 96.7 % predicted. The median diffusing capacity of the lungs for carbon monoxide (DLCO) was 58.5 % predicted and was decreased in 79 % of the patients. The median 6-minute walk distance was 535 m, which was 90.9 % of the 602 m predicted distance. The median DSP was 497.4 m % and the median 6MWORK was 32,910 kg.m. The distance walked during the 6MWT was significantly correlated with FVC%predicted (R = 0.435), FEV1 %predicted (R = 0.303), TLC%predicted (R = 0.345), FRC%predicted (R = 0.262), RV/TLC ratio (R = -0.271), and DLCO%predicted (R = 0.279). DSP and 6MWORK were each significantly correlated with different PFT results. CONCLUSION: The present study shows that PFT results are potential predictors of the exercise capacity in patients with LAM. Additional studies are required to evaluate the interest of DSP and 6MWORK in LAM.

Neutrophilic dermatosis and hidradenitis suppurativa in patients with Behçet's disease: A neutrophilic disease in the spectrum of autoinflammatory syndromes.

BACKGROUND: Association of neutrophilic dermatosis (ND), hidradenitis suppurativa (HS) and Behçet's disease (BD) and shared efficacy of TNFα axis blockade suggests common physiopathology. OBJECTIVES: To investigate the clinical features and therapeutic response of ND and HS associated with BD. METHODS: We identified 20 patients with ND or HS associated with BD among 1462 patients with BD. RESULTS: We analysed 20 (1.4%) patients diagnosed with ND or HS associated with BD: 13 HS, 6 pyoderma gangrenosum (PG), and 1 SAPHO. Our 6 PG cases over 1462 BD patients accounts for 400/100 000 prevalence. Thirteen had bipolar aphthosis, 6 vascular, 5 neurologic, and 4 ocular involvements. All PG occurred on limbs and had typical histology with constant dermal neutrophilic infiltrate. All HS had the classical axillary-mammary phenotype. Sixty-nine percent (69%) of HS were Hurley 1 stage. Treatment consisted mainly in colchicine (n = 20), glucocorticoids (n = 12), and anti-TNFα (n = 9). Interesting results with complete or partial responses were obtained with anti-TNFα (9 cases), ustekinumab (3 cases) and tocilizumab (1 case) to treat refractory ND or HS associated with BD. CONCLUSION: PG seems overrepresented in patients with BD. Biotherapies such as anti-TNFα, ustekinumab and tocilizumab appear to be promising to treat refractory ND or HS associated with BD.

Epidemiological study of opioid use disorder in French emergency departments, 2010-2018 from OSCOUR database.

OBJECTIVES: Opioid consumption in France has remained stable over the last 15 years, with much lower levels than in the USA. However, few data are available on patients who consume opioids and their use of the health system. Emergency department (ED) data has never been used as a source to investigate opioid use disorder (OUD) in France. DESIGN/SETTINGS/PARTICIPANTS: We used the OSCOUR national surveillance network, collecting daily ED data from 93% of French ED, to select and describe visits and hospitalisations after an OUD-related ED visit between 2010 and 2018 using International Classification of Diseases, version 10 (ICD10) codes. We described the population of interest and used binomial negative regressions to identify factors significantly associated with OUD such as gender, age, administrative region, year of admission and ICD10 codes. We also analysed the related diagnoses. PRIMARY OUTCOME MEASURE: Trend in ED visits for an OUD-related ED visit. RESULTS: We recorded 34 362 OUD-related visits out of 97 892 863 ED visits (36.1/100 000 visits). OUD-related visits decreased from 39.2/100 000 visits in 2010 to 32.9/100 000 visits in 2018, resulting in an average yearly decrease of 2.1% (95% CI 1.5% to 2.7%) after multivariate analysis. We recorded 15 966 OUD-related hospitalisations out of 20 359 574 hospitalisations after ED visits (78.4/100 000 hospitalisations) with an increase from 74.0/100 000 hospitalisations in 2010 to 81.4/100 000 hospitalisations in 2018. The analysis of related diagnoses demonstrated mostly polydrug abuse in this population. CONCLUSIONS: While the proportion of OUD visits decreased in the time frame, the hospitalisation proportion increased. The implementation of a nationwide surveillance system for OUD in France using ED visits would provide prompt detection of changes over time.
