Abstract
OBJECTIVES To describe a concept of standardized preoperative one-day evaluation before urinary reconstructive or diversion surgery for the treatment of neurogenic lower urinary tract (LUT) dysfunction, and to evaluate its feasibility and its impact on the care pathway. MATERIALS AND METHODS All patients who underwent a one-day standardized evaluation before a urinary reconstructive or derivation surgery for the treatment of neurogenic LUT dysfunction between January 2017 and December 2021 in our institution were included. Data were collected retrospectively from standardized reports. The main outcome was the rate of completion of the tests and consultations planned during this evaluation. Secondary outcomes included the findings from the one-day evaluation and changes in the urological surgical strategy at different time points within one year. RESULTS One hundred and thirty-one patients benefited from this one-day standardized evaluation. The overall completeness rate of the data collected was 77.5%, increasing from 62.3% in 2017 to 89.3% in 2021. The urological surgical plan was modified for 19.1% of patients following this preoperative evaluation. The indication was then confirmed for 114 patients (87.0%) by the multidisciplinary meeting and was carried out unchanged during the following year for 89 patients (67.9%). An associated colostomy procedure was proposed for 18.3% of patients and was finally performed in 11.5%. CONCLUSION A standardized multidisciplinary preoperative one-day evaluation before performing reconstructive or diversion surgery for the treatment of neurogenic LUT dysfunction seems feasible and makes it possible to optimize the surgical plan and adapt the course of care.

Abstract
PURPOSE The study sought to estimate the prevalence of primary non-aortic lesions (PNAL) unrelated to extension of aortic dissection (AD) in a cohort of patients with Marfan syndrome (MFS). METHODS Adult patients presenting with pathogenic FBN1 mutations and an available pan-aortic contrast-enhanced CTA in eight French MFS clinics from April to October 2018 were included. Clinical and radiological data, particularly the presence of aortic lesions and PNAL (including aneurysm and ectasia), were retrospectively analyzed. RESULTS Out of 138 patients, 28 (20.3%) had PNAL. In total, 27 aneurysms in 13 patients and 41 ectasias in 19 patients were reported mainly in the subclavian, iliac, and vertebral segments. Four patients (31%) with aneurysms and none with ectasia required prophylactic intervention during follow-up (median: 46 months). In multivariate analysis, factors associated with PNAL were history of AD (OR = 3.9, 95%CI: 1.3-12.1, p = 0.018), history of previous descending aortic surgery (OR = 10.3, 95%CI: 2.2-48.3, p = 0.003) and age (per 10 years OR = 1.6, 95%CI: 1.1-2.4, p = 0.008). CONCLUSION PNAL is not rare in MFS patients with evolutive aortic disease. Natural history may differ between aneurysms and ectasia, emphasizing the need for standardized definitions and systematic screening for PNAL.

Abstract
Genotyping of Staphylococcus aureus isolated from mastitis has become a fundamental tool to understand its complex epidemiology and to evaluate spillover events. The aim of this study was to describe the frequency of genotypes of the S. aureus strains isolated from intramammary infections by spa typing technique, and to evaluate the association between genotypes and the ability to form biofilm under in vitro conditions. Sixty-six strains of S. aureus recovered from bovines intramammary infections on 56 dairy herds located in 14 municipalities of the department of Antioquia were characterized. The majority of strains (65/66) were isolated from milk samples collected from dairy cows with subclinical intramammary infections. Nineteen different spa types were found in this study, t521 (19.70%), t267 (15.15%), and t605 (12.12%) being the most frequent. The strains from the t605 spa type showed the highest biofilm production. The high frequency of spa types with zoonotic potential found in this study, identified cattle as an important reservoir of theses clones for people in close proximity, such as milkers and consumers of unpasteurized dairy products.

Abstract
Cetaceans adjust their distribution and abundance to encountered conditions across years and seasons, but we poorly understand such small-scale changes for many species, especially in winter. Crucial challenges confront some populations during this season, such as the high levels of fisheries-induced mortality faced by the common dolphin (Delphinus delphis) in the Northeast Atlantic shelves. For such species, understanding the winter fine-scale dynamics is crucial. We aimed to identify the dolphin distribution drivers during the winters of 2020 and 2021, with a focus on determining the lag between changes in oceanographic conditions and dolphin distribution. The changes were related to temporal delays specific to the nature and cascading effects that oceanographic processes had on the trophic chain. By determining the most important conditions and lags to dolphin distributions, we shed light on the poorly understood intrusions of dolphins within coastal waters during winter: they displayed a strong preference for the coastal-shelf waters front and extensively followed its spatial variations, with their overall densities increasing over the period and peaking in March-April. The results presented here provide invaluable information on the winter distribution dynamics and should inform management decisions to help reduce the unsustainable mortalities of this species in the by-catch of fisheries.

Abstract
Background: The aim of this study was to evaluate the aortic diameter and volume during the first year after a type A repair to predict the long-term prognosis of a residual aortic dissection (RAD). Methods: All patients treated in our center for an acute type A dissection with a RAD and follow-up > 3 years were included. We defined two groups: group 1 with dissection-related events (defined as an aneurysmal evolution, distal reintervention, or aortic-related death) and group 2 without dissection-related events. The aortic diameters and volume analysis were evaluated on three postoperative CT scans: pre-discharge (T1), 3−6 months (T2) and 1 year (T3). Results: Between 2009 and 2016, 54 patients were included. Following a mean follow-up of 75.4 months (SD 31.5), the rate of dissection-related events was 62.9% (34/54). The total aortic diameters of the descending thoracic aorta were greater in group 1 at T1, T2 and T3, with greater diameters in the FL (p < 0.01). The aortic diameter evolution at 3 months was not predictive of long-term dissection-related events. The total thoracic aortic volume was significantly greater in group 1 at T1 (p < 0.01), T2 (p < 0.01), and T3 (p < 0.01). At 3 months, the increase in the FL volume was significantly greater in group 1 (p < 0.01) and was predictive for long-term dissection-related events. Conclusion: This study shows that an initial CT scan volume analysis coupled with another at 3 months is predictive for the long-term evolution in a RAD. Based on this finding, more aggressive treatment could be given at an earlier stage.

Abstract
Introduction: Inulin and its analog sinistrin are fructose polymers used in the food and pharmaceutical industries. In 2018, The French National Agency for the Safety of Medicines and Health Products (ANSM) decided to withdraw products containing sinistrin and inulin due to several reports of serious hypersensitivity reactions, including a fatal outcome. Objective: To assess the safety of inulin and sinistrin use in France. Methods: We searched multiple sources to identify adverse reactions (ARs) to inulin or sinistrin: first, classical pharmacovigilance databases including the French Pharmacovigilance (FPVD) and the WHO Database (VigiBase); second, data from a clinical trial, MultiGFR; third, data regarding current use in an hospital. All potential ARs to inulin or sinistrin were analyzed with a focus on hypersensitivity reactions and relationships to batches of sinistrin. Results: From 1991 to 2018, 134 ARs to inulin or sinistrin were registered in the FPVD or VigiBase. Sixty-three cases (47%) were classified as serious, and 129 cases (96%) were hypersensitivity reactions. We found an association between a batch of sinistrin and the occurrence of hypersensitivity reactions. During the MultiGFR clinical trial, 7 patients (7/163 participants) had an Adverse reaction; of these, 4 were hypersensitivity reactions including one case of grade 4 anaphylactic shock. In the hospital, no ARs were observed. In the literature, ARs to inulin and sinistrin are very rarely reported and mostly benign. Conclusion: Most ARs to inulin and sinistrin are hypersensitivity reactions that appear to be associated with sinistrin batches.

Abstract
OBJECTIVES We investigated the anatomical evolution of residual aortic dissection after type A repair and factors associated with poor prognosis at a high-volume aortic centre. METHODS Between 2017 and 2019, all type A aortic dissections were included for prospective follow-up. Patients without follow-up computed tomography (CT) scan available for radiological analysis and patients without residual aortic dissection were excluded from this study. The primary end point was a composite end point defined as dissection-related events including aneurysmal evolution (increased diameter > 5 mm/year), aortic reintervention for malperfusion syndrome, aortic diameter >55 mm, rapid aortic growth >10 mm/year or aortic rupture and death. The secondary end points were risk factors for dissection-related events and reintervention analysis. All immediate and last postoperative CT scans were analysed. RESULTS Among 104 patients, after a mean follow-up of 20.4 months (8-41), the risk of dissection-related events was 46.1% (48/104) and the risk of distal reintervention was 17.3% (18/104). Marfan syndrome (P < 0.01), aortic bicuspid valve (P = 0.038), innominate artery debranching (P = 0.025), short aortic cross-clamp time (P = 0.011), initial aortic diameter >40 mm (P < 0.01) and absence of resection of the primary entry tear (P = 0.015) were associated with an increased risk of dissection-related events or reintervention during follow-up. CONCLUSIONS Residual aortic dissection is a serious disease requiring close follow-up at an expert centre. This study shows higher reintervention and aneurysmal development rates than currently published. To improve long-term outcomes, the early demographic and anatomic poor prognostic factors identified may be used for more aggressive treatment at an early phase.

Abstract
Introduction Myocardial injury is frequently observed in patients hospitalized with Coronavirus disease 2019 (COVID-19) pneumonia. Different cardiac abnormalities have been reported during the acute COVID-19 phase but there is limited information on late cardiac sequelae in patients who have recovered from acute COVID-19 illness. Objective To document the presence and quantify the extent of myocardial functional alterations in patients hospitalized 6 months earlier for COVID-19 infection. Methods and results We conducted a prospective echocardiographic evaluation of 48 patients (58 ± 13 years, 69% male) hospitalized 6 ± 1 month earlier for a laboratory-confirmed and symptomatic COVID-19. Thirty-two (66.6%) had pre-existing cardiovascular risks factors (hypertension, T2DM or dyslipidemia) and three patients (6.2%) had a known prior myocardial infarction. Sixteen patients (33.3%) experienced myocardial injury during the index COVID-19 hospitalization as identified by a rise in cardiac troponin levels. Six months later, 60.4% of patients still reported clinical symptoms including exercise dyspnea for 56%. Echocardiographic measurements under resting conditions were not different between patients with vs. without myocardial injury during the acute COVID-19 phase. In contrast, low-level exercise (25 W for 3 minutes) induced a significant increase in the average E/e’ ratio (10.1 ± 4.3 vs. 7.3 ± 11.5, P = 0.01) and the systolic pulmonary artery pressure (33.4 ± 7.8 vs. 25.6 ± 5.3 mmHg, P = 0.02) in patients with myocardial injury during the acute COVID-19 phase. Sensitivity analyses showed that these alterations of left ventricular diastolic markers were observed regardless of cardiovascular disorders indicating SARS-CoV-2 infection as a primary cause. Conclusions Six months after the acute COVID-19 phase, significant cardiac diastolic abnormalities are observed in patients who experienced myocardial injury but not in patients without cardiac involvement.

Abstract
OBJECTIVE There are no recommendations for screening for thoracic aortic aneurysms (TAAs), even in patients with infrarenal abdominal aortic aneurysms (AAAs). The aims of this study were to determine the prevalence of TAAs in patients with AAAs and to analyse the risk factors for this association. METHODS This was a multicentre prospective study. The Aortic Concomitant Thoracic and Abdominal Aneurysm (ACTA) study included 331 patients with infrarenal AAAs > 40 mm between September 2012 and May 2016. These patients were prospectively enrolled in three French academic hospitals. RESULTS Patients were classified as having a normal, aneurysmal, or ectatic (non-normal, non-aneurysmal) thoracic aorta according to their maximum aortic diameter indexed by sex, age, and body surface area. Thoracic aortic ectasia (TAE) was defined as above or equal to the 90th percentile of normal aortic diameters according to gender and body surface area. Descending TAA was defined as ≥ 150% of the mean normal value, and ascending TAA as > 47 mm in men and 42 mm in women; 7.6% (n = 25) had either an ascending (seven cases; 2.2%) or descending aortic TAA (18 cases; 5.4%), and 54.6% (n = 181) had a TAE. Among the 25 patients with TAAs, five required surgery; two patients had TAAs related to penetrating aortic ulcers < 60 mm in diameter, and three had a TAA > 60 mm. In the multinomial regression analysis, atrial fibrillation (AF) (odds ratio [OR] 11.36, 95% confidence interval [CI] 2.18 - 59.13; p = .004) and mild aortic valvulopathy (OR 2.89, 1.04-8.05; p = .042) were independent factors associated with TAAs. Age (OR 1.06, CI 1.02 - 1.09; p = .003) and AF (OR 4.36, 1.21 - 15.61; p = .024) were independently associated with ectasia. CONCLUSION This study confirmed that TAAs coexisting with AAAs are not rare, and one fifth of these TAAs are treated surgically. Systematic screening by imaging the whole aorta in patients with AAAs is clinically relevant and should lead to an effective prevention policy.

Abstract
1. This study investigated the oxidative status of broilers fed diets containing selenium (Se) from 14 to 35 d of age and reared at two different constant temperatures. Measurements of oxidative status included blood glutathione peroxidase (GSH-Px) and plasma total antioxidant status (TAS). Other variables included feed intake (FI), weight gain (WG), feed conversion ratio (FCR), Se levels in breast and liver tissue, jejunal villus morphometry, percentage weight of organs in relation to body weight; apparent metabolisable energy adjusted for nitrogen (AMEn); dry matter retention (DMR); fat retention (FR) and nitrogen retention (NR).2. The experiment started at 14 d of age, when 240 birds were randomly allocated to 48 pens (12 pens in four rooms). Treatments included a control diet 1 (SFC; 209.4 g/kg CP and 12.98 MJ/kg ME and no added Se containing saturated fat); diet 2 (SFSe) the control plus 12.605 mg/kg Se additive; diet 3 (USFC) was a second control diet (208.2 g/kg CP and 13.10 MJ/kg ME with no added Se containing unsaturated fat as rapeseed oil); diet 4 (USFSe) was the latter control plus 12.605 mg/kg Se additive. Two rooms were kept at a standard temperature of 20°C (ST) and two rooms were kept at high temperature of 35°C (HT).3. A temperature x Se interaction existed for GSH-Px in birds reared at ST (P < 0.05), and these birds had the highest levels of Se in liver tissue (P < 0.05). Fat x Se interactions were evident in breast tissue with highest levels in USFSe (P < 0.05). Adding Se improved jejunal VH: CD in USFSe fed birds (P < 0.001).4. Birds reared at ST had higher FI and WG than those reared at HT (P < 0.001), and had lower FCR than those reared at HT (P < 0.05). AMEn (MJ/kg DM) and FR were higher in birds fed USF diets, and lowest in birds fed SF (P < 0.50 and P < 0.001 respectively). NR was highest in birds raised at ST (P < 0.50).5. Broiler growth performance was reduced by HT. Oxidative status and Se in liver tissue was improved by adding Se in both diets.

Abstract
1. This study examined the effects of different dietary sources and levels of selenium (Se) on growth performance, hepatic and breast meat Se content, glutathione peroxidase (GSH-Px) activity and total antioxidant status (TAS) in blood, when fed to broilers from 14 to 35 d of age and reared at two different temperatures (20°C and 35°C). 2. Five hundred and sixty male Ross 308 broilers were reared in a single floor pen and fed the same proprietary starter diet from 0 to 14 d age (229.9 g/kg CP and 12.67 MJ/kg ME, without Se supplementation). 3. The experiment started at 14 d age, and the birds randomly assigned to 112 raised-floor pens (0.36 m2 area, 5 birds/pen). Each of the seven experimental diets were offered to birds in 16 pens within four rooms. Two rooms were at 20°C and two rooms were maintained at 35°C. The experimental diets were fed from 14 to 35 d age and contained 214.9 g/kg CP and 13.11 MJ/kg ME. The experimental diets were as follows; control diet containing background Se only (0.189 mg/kg; C); low level sodium selenite (0.376 mg/kg; LSS): high level sodium selenite (0.558 mg/kg; HSS); low level commercial B Traxim® Se (0.244 mg/kg) (LBT); high level B Traxim® Se (0.448 mg/kg; HBT); low level selenised yeast (0.290 mg/kg; LSY); high level selenised yeast (0.487 mg/kg; HSY). 4. Birds consumed more when raised at 20°C compared to birds reared at 35°C (P ≤ 0.05). Birds fed lower Se level reared at 35°C had higher weight gain versus those fed higher Se level (P < 0.05). Birds fed SY had the lowest feed intake, weight gain and FCE (P < 0.05). The greatest GSH-Px activity was observed in birds fed SS diets (P < 0.001). There were interactions between diet x level for TAS, which were highest in birds fed LBT compared to birds fed HBT (P < 0.05). Breast Se content was higher in birds fed HSY compared to LSY (P < 0.001). The highest hepatic Se was seen in birds fed SY and lowest in C (P < 0.001). 5. Birds fed BT diets showed similar levels of Se to those birds fed inorganic Se, and similar levels of GSH-Px to birds fed SY. Further comparative work with broilers fed BT and other Se supplemented diets may elucidate the findings from this report.

Abstract
1. This study was conducted to determine the effect of different sources of selenium (Se) on breast and liver tissue deposition, apparent metabolisable energy (AME), growth performance and antioxidant status of broilers, measured as Se content in liver and breast tissues and glutathione peroxidase (GSH-Px) in blood, when used in 0-35 d broiler chicken diets. 2. A total of 200 male Ross 308 broilers were used in the feeding trial, which comprised two dietary phases, a starter from 0 to 21 d and finisher from 21 to 35 d of age. Four treatments with 10 replications each were used. A control diet (C) was formulated that was sufficient in protein and energy (230 and 215 g/kg of crude protein and 12.67 and 13.11 MJ/kg of metabolisable energy, respectively), for both phases, but contained background Se only from the feed ingredients. Diet 2 (IS) was supplemented with 10.35 g/t inorganic, elemental source of Se. Diet 3 (SY) was supplemented with 136.36 g/t selenised yeast, an organic source derived from Saccharomyces cerevisiae. Diet 4 (SS) was supplemented with 0.666 g/t sodium selenite, an inorganic source. 3. Birds fed the SY diet consumed less and weighed less than those fed IS or C (P < 0.05; 0-35 d of age), but there was no difference compared to birds fed SS diets. There were no differences in FCR or dietary AME between broilers fed different Se sources. All diets containing supplementary Se increased concentrations in the liver and breast muscle, and for GSH-Px levels in blood compared to birds fed the C diet (P < 0.001). Birds fed SY diets had greater Se levels in liver and breast tissues compared to birds fed any of the other diets (P < 0.001). 4. Diets supplemented with Se had variable effects on broiler growth performances and antioxidant status. Feeding Se from a yeast source has higher transfer into breast tissues. Feeding different sources and levels of Se to birds in a more challenging situation to induce oxidative stress may bring more conclusive results.

Abstract
BACKGROUND The natural history of type B intramural hematomas is little-known. Aneurysmal progression or an aortic dissection occurs in 15 to 20% of the cases. The study of the natural anatomical evolution could help identify the patients at risk of unfavorable evolution. METHODS All the patients monitored for a type B intramural hematoma between 2009 and 2018 were included in this monocentric retrospective study. Computed tomography angiography centerline measurement of diameters was obtained in various points of aortic segmentation on day (D) 0 and at one month (M1). Aortic volumes (lumen, intramural hematoma, and total volume) were calculated. The circulating volume was calculated using the volume rendering method. The volume of the intramural hematoma was measured using a manual section-by-section segmentation tool, and the total volume was obtained by summing up the two preceding volumes. Two groups of patients were compared: group 1 (favorable anatomical evolution) and group 2 (unfavorable anatomical evolution). RESULTS Between January 2008 and August 2018, 25 patients were managed for a type B intramural hematoma in our center. After an average follow-up of 15.5 months (1-52), 13 patients (52%) presented a favorable evolution and 12 (48%) an unfavorable evolution. At M1, a significant increase of the luminal diameters (37 mm vs. 32 mm; P < 0.01) and a significant reduction in the longitudinal extension (19 mm vs. 26 mm; P < 0.01) were observed. The maximum aortic diameter evolved significantly between D0 and M1 in the unfavorable evolution group (49 mm vs. 44 mm, respectively; P = 0.038). Such a difference was not found in the favorable evolution group (37.4 vs. 37.1, respectively; P = 0.552). An overall significant reduction in the total aortic volume (166 cm3 vs. 219 cm3; P < 0.01), the circulating volume (124 cm3 vs. 145 cm3; P = 0,026), and the volume of the hematoma (42 cm3 vs. 39 cm3; P < 0.01) was observed. The circulating volume decreased significantly between D0 and M1 in the favorable evolution group (110 cm3 vs. 135 cm3; P = 0.05), whereas no difference was noted in the unfavorable group (142 cm3 vs, 157 cm3; P = 0.24). CONCLUSIONS The progression of the maximum aortic diameter and of the circulating volume after one month of follow-up could be predictive factors of the poor long-term evolution of type B intramural hematomas.

Abstract
The aim of this article is to examine the impacts of incorporating sex and gender (s/g) analysis in integrated knowledge translation (iKT) initiatives in the field of ergonomics and occupational health. The article presents findings based on a retrospective analysis of twelve intervention-research (IR) studies, including a thematic content analysis of in-depth interviews conducted with 15 researchers involved in these IRs. The findings offer an overview of various categories of impacts, such as changes in partners' views, in workplace settings and conditions, in practices and policies, and in economic outcomes. In these types of IR, health effects measurement is not the main objective, and direct health outcomes are difficult to assess. Explicitly talking about sex/gender led more often to system-level changes but less often to workplace-level changes, compared to interventions where sex/gender was not identified as a specific object of the intervention.

Abstract
Abstract
Introduction
Hypertension is one of the major contributors to cardiac diastolic dysfunction as observed in patients with heart failure and preserved ejection fraction. Different therapeutics strategies have been proposed to control blood pressure (BP) but their independent impact on cardiac function remain undetermined. In patients referred to our center for uncontrolled hypertension, we compared changes in cardiac parameters between two strategies consisting of sequential nephron blockade with intensive diuretics (NBD) or sequential renin angiotensin blockade (RAB).
Purpose
To determine evolution of BNP levels and echocardiographic (TTE) parameters of diastolic dysfunction according to strategies to control BP.
Methods
After 4-weeks treatment with 300mg irbesartan + 12.5mg hydrochlorothiazide + 5mg amlodipine, 140 patients with uncontrolled hypertension were randomized to either complete nephron blockade with sequential introduction of 25mg spironolactone, 20 to 40mg furosemide and 5mg amiloride (NBD group, n=74) or complete RAAS blockade with 5 to 10mg ramipril and 5 to 10mg bisoprolol (RAB group, n=67). BNP levels and TTE parameters according to ESC guidelines were assessed at baseline and week 12.
Results
BNP levels were not significantly different in the two groups at baseline (mean±SD 30.1±37.0pg/mL in NBD versus 22.6±22.3pg/mL in RAB, p=0.147) but significantly decreased in NBD at week 12 (20.1±22.7pg/mL in NBD versus 55.2±60.4pg/mL in RAB, p<0.0001). At week 12, only 9 (12%) patients in NBD presented BNP levels >35pg/mL versus 37 (55%) in RAB (p<0.001).
Concordantly, TTE parameters such as left ventricular end-diastolic diameter (mean±SD, 49±4mm in NBD and 52±5mm in RAB, p=0,004) and left atrial area (16.9±3.6cm2 in NBD and 19.1±3.7cm2 in RAB, p=0,003) improved significantly in NBD group. The proportions of patients presenting ≥2 criteria of diastolic dysfunction according to ESC guidelines in NBD and RAB group respectively were 31.2% and 19.3% at baseline vs. 3.1% and 32.2% after 12 weeks (p=0.001). In a multivariate analysis, NBD treatment was significantly associated with a decline in BNP levels (p<0.01) even after adjustment on daytime systolic BP lowering, heart rate, renal function, age and gender.
Conclusion
In patients with uncontrolled hypertension, intensive nephron blockade with sequential addition of diuretics improves markers of diastolic dysfunction independently of BP lowering.

Abstract
INTRODUCTION To compare non-continent urinary diversion (NCUD) and other bladder managements in patients with multiple sclerosis (MS), in terms of satisfaction and burden of care. MATERIAL AND METHODS All patients with MS that were proposed a NCUD in our center for refractory lower urinary tract disorders between January 2005 and March 2018 were eligible. Patients were attributed to two distinct groups: "NCUD" and "Other bladder management". The primary endpoint was the satisfaction related to the bladder management quoted by a numerical rating scale (NRS) from 0 to 10. The secondary endpoints included, among other things, the evaluation of the burden of care associated with the bladder management. RESULTS Twenty-three patients were included in the "NCUD" group and 11 in the "Other bladder management" group, with 4 patients pursuing with spontaneous voiding, 3 with intermittent catheterization, 2 that have undergone a sphincterotomy, 1 still performing self-intermittent catheterization and 1 with a supra-pubic catheter. The "NCUD" group had a significant higher NRS than the "Other bladder management" group (8.22±1.78 vs. 6.27±2.45; P=0.0056). The daily average duration of care was 16.42minutes in the "NCUD" group and 35.6minutes in the "Other bladder management" group (P=0.1111) CONCLUSION: This exploratory study, even if not conclusive, brings to light the preliminary results needed to elaborate a high level of evidence protocol regarding the satisfaction and the burden of care associated with NCUD in MS patients. LEVEL OF EVIDENCE 4.

Abstract
Objective Immune checkpoint inhibitors are now a standard of care for the management of many metastatic cancers, including non-small-cell lung cancer. Pembrolizumab, a selective anti-PD-1 monoclonal antibody, augments the host antitumoural response. This hyperactivation of the immune system has side effects, the so-called immune-related adverse effects. The objective of this case report was to review and point out a new pattern of immune checkpoint inhibitor-associated pneumonitis. Case Description A 69-year-old woman with stage iv non-small-cell lung cancer receiving pembrolizumab presented for increased dyspnea. Pembrolizumab-related obstructive bronchiolitis was diagnosed based on a new severe obstructive disorder, without bronchodilator reversibility, and mosaic attenuation on angiography, without other identifiable causes. Summary To our knowledge, this is the first description of a case of pembrolizumab-induced obstructive bronchiolitis. Various patterns of immune checkpoint inhibitor-associated lung disease have been described, and bronchiolitis should be included in the differential diagnosis.

Abstract
Diepoxybutane (DEB) is the most potent active metabolite of butadiene, a regulated air pollutant. We previously reported the occurrence of DEB-induced, p53-dependent, mitochondrial-mediated apoptosis in human lymphoblasts. The present study investigated the role of the extracellular signal-regulated protein kinases 1 and 2 (ERK1/2) pathway in DEB-induced apoptotic signaling in exposed human lymphoblasts. Activated ERK1/2 and mitogen-activated protein (MAP) kinase/ERK1/2 kinase (MEK) levels were significantly upregulated in DEB-exposed human lymphoblasts. The MEK inhibitor PD98059 and ERK1/2 siRNA significantly inhibited apoptosis, ERK1/2 activation, as well as p53 and phospho-p53 (serine-15) levels in human lymphoblasts undergoing DEB-induced apoptosis. Collectively, these results demonstrate that DEB induces apoptotic signaling through the MEK-ERK1/2-p53 pathway in human lymphoblasts. This is the first report implicating the activation of the ERK1/2 pathway and its subsequent role in mediating DEB-induced apoptotic signaling in human lymphoblasts. These findings contribute towards the understanding of DEB toxicity, as well as the signaling pathways mediating DEB-induced apoptosis in human lymphoblasts.

Abstract
Every year in France, nearly 50 infants live in a prison nursery with their mother. According to French law, infants can live with their mother in the prison nursery until they reach 18 months of age. The international community is concerned about the lack of validated social, medical and legal data on these infants living in prison. This was a retrospective and descriptive study. Medical and paramedical files of the General Council of Île-et-Vilaine, France, were studied. Every infant born between 1998 and 2013 while their mother was in prison were included. Fifty-four files were collected. The average length of stay was 6.2 months (n=54). The type of the mother's prison sentence was property damage in 40 % of cases, personal injury in 51.1 % of cases and both in 8.9 % of cases (n=45). The length of the mother's imprisonment was on average 45 months, ranging from 3 to 216 months (n=34). After prison, 42.9 % of the infants were placed in foster care and 57.1 % resided with their family (n=42). This child-mother incarceration could be an opportunity for positive intergenerational paramedical, medical and social services. The lack of data and problems collecting data restrict our knowledge of these families. This should motivate a national follow-up for these children.

Abstract
Intestinal strongyles are the most problematic endoparasites of equids as a result of their wide distribution and the spread of resistant isolates throughout the world. While abundant literature can be found on the extent of anthelmintic resistance across continents, empirical knowledge about associated risk factors is missing. This study brought together results from anthelmintic efficacy testing and risk factor analysis to provide evidence-based guidelines in the field. It involved 688 horses from 39 French horse farms and riding schools to both estimate Faecal Egg Count Reduction (FECR) after anthelmintic treatment and to interview farm and riding school managers about their practices. Risk factors associated with reduced anthelmintic efficacy in equine strongyles were estimated across drugs using a marginal modelling approach. Results demonstrated ivermectin efficacy (96.3% ± 14.5% FECR), the inefficacy of fenbendazole (42.8% ± 33.4% FECR) and an intermediate profile for pyrantel (90.3% ± 19.6% FECR). Risk factor analysis provided support to advocate for FEC-based treatment regimens combined with individual anthelmintic dosage and the enforcement of tighter biosecurity around horse introduction. The combination of these measures resulted in a decreased risk of drug resistance (relative risk of 0.57, p = 0.02). Premises falling under this typology also relied more on their veterinarians suggesting practitionners play an important role in the sustainability of anthelmintic usage. Similarly, drug resistance risk was halved in premises with frequent pasture rotation and with stocking rate below five horses/ha (relative risk of 0.53, p < 0.01). This is the first empirical risk factor analysis for anthelmintic resistance in equids. Our findings should guide the implementation of more sustained strongyle management in the field. 688 horses have been enrolled for Egg reduction rate measure. Ivermectin remains efficient but fendendazole is not any more. Evidence-based drenching and individual dosing lower resistance risk. Higher biosecurity is associated with higher drug efficacy. Premises with the least pasture constraints show higher drug efficacy.

Abstract
Essentials Rivaroxaban and dabigatran are substrates of the P-glycoprotein (P-gp) encoded by the ABCB1 gene. We tested the effect of ABCB1 polymorphisms and of a P-gp inhibitor on both drugs' pharmacokinetics. The ABCB1 genotype was not a clinically relevant determinant of both drugs' pharmacokinetics. Administration of P-gp inhibitors with dabigatran or rivaroxaban should be exercised with caution. SUMMARY Background The direct oral anticoagulants (DOACs) dabigatran and rivaroxaban are both substrates of the P-glycoprotein (P-gp) transporter, encoded by the ABCB1 gene. Rivaroxaban is metabolized by cytochrome P450 A4 (CYP3A4). Interindividual variability in DOAC exposure and frequent P-gp-associated drug-drug interactions have been described in patients. Objective To assess the influence of ABCB1 polymorphisms on the pharmacokinetics of dabigatran and rivaroxaban, associated or not with clarithromycin, a P-gp and CYP3A4 inhibitor. Methods Sixty healthy male volunteers, selected according to ABCB1 genotype (20 homozygous mutated, 20 heterozygous mutated, and 20 wild-type for haplotype 2677-3435), were included in this randomized, two-center, crossover study. All received sequentially a single dose of dabigatran etexilate (300 mg) and rivaroxaban (40 mg) associated or not with clarithromycin. Peak plasma concentration and area under the curve (AUC) were compared across the three ABCB1 genotypes. The effect of clarithromycin on dabigatran or rivaroxaban pharmacokinetics was assessed. Results Interindividual coefficients of variation for AUC were 77% for dabigatran and 51% for rivaroxaban. ABCB1 genotype did not significantly affect drug pharmacokinetics: AUC ratios between mutant-allele carriers and wild-type volunteers were 1.27 (95% confidence interval [CI] 0.84-1.92) and 1.20 (95% CI 0.96-1.51) for dabigatran and rivaroxaban, respectively. Clarithromycin coadministration led to a two-fold increase in both drugs' AUC, irrespective of ABCB1 genotype: ratios of geometric means were 2.0 (95% CI 1.15-3.60) and 1.94 (95% CI 1.42-2.63) for dabigatran and rivaroxaban, respectively. Conclusions ABCB1 genotype is not a significant determinant of interindividual variability in dabigatran and rivaroxaban pharmacokinetics. The levels of one drug did not predict the levels of the other. Coadministration of a P-gp/CYP3A4 inhibitor with dabigatran or rivaroxaban may warrant caution in patients at risk of overexposure.

Abstract
Adoption of next-generation sequencing (NGS) in a diagnostic context raises numerous questions with regard to identification and reports of secondary variants (SVs) in actionable genes. To better understand the whys and wherefores of these questioning, it is necessary to understand how they are selected during the filtering process and how their proportion can be estimated. It is likely that SVs are underestimated and that our capacity to label all true SVs can be improved. In this context, Locus-specific databases (LSDBs) can be key by providing a wealth of information and enabling classifying variants. We illustrate this issue by analyzing 318 SVs in 23 actionable genes involved in cancer susceptibility syndromes identified through sequencing of 572 participants selected for a range of atherosclerosis phenotypes. Among these 318 SVs, only 43.4% are reported in Human Gene Mutation Database (HGMD) Professional versus 71.4% in LSDB. In addition, 23.9% of HGMD Professional variants are reported as pathogenic versus 4.8% for LSDB. These data underline the benefits of LSDBs to annotate SVs and minimize overinterpretation of mutations thanks to their efficient curation process and collection of unpublished data.

Abstract
Whole‐exome sequencing (WES) is increasingly applied to research and clinical diagnosis of human diseases. It typically results in large amounts of genetic variations. Depending on the mode of inheritance, only one or two correspond to pathogenic mutations responsible for the disease and present in affected individuals. Therefore, it is crucial to filter out nonpathogenic variants and limit downstream analysis to a handful of candidate mutations. We have developed a new computational combinatorial system UMD‐Predictor (http://umd‐predictor.eu) to efficiently annotate cDNA substitutions of all human transcripts for their potential pathogenicity. It combines biochemical properties, impact on splicing signals, localization in protein domains, variation frequency in the global population, and conservation through the BLOSUM62 global substitution matrix and a protein‐specific conservation among 100 species. We compared its accuracy with the seven most used and reliable prediction tools, using the largest reference variation datasets including more than 140,000 annotated variations. This system consistently demonstrated a better accuracy, specificity, Matthews correlation coefficient, diagnostic odds ratio, speed, and provided the shortest list of candidate mutations for WES. Webservices allow its implementation in any bioinformatics pipeline for next‐generation sequencing analysis. It could benefit to a wide range of users and applications varying from gene discovery to clinical diagnosis.

Abstract
We study the dynamics of a linear, uniform, undamped string under harmonic base excitation, with an attachment consisting of either a spring–dashpot system or a vibration absorber. Mode complexity caused by the local damping of the attachment can lead to coexistence of vibrations and waves in the string. We consider either identical harmonic base motions at both ends or harmonic base excitation at one end. In the case of double harmonic base excitation, it is possible to choose the parameters of the attachment, so that the mode complexity is maximal in one part of the string (leading to travelling waves and elimination of vibrations) and almost zero in the other part (with standing waves or vibration modes). Similarly, for single base excitation, we analytically predict the parameters of the attachment that maximize mode complexity and enhance the interplay of vibrations and travelling waves in the string. Under such conditions, the system acts as a passive vibration confinement device, with induced energy being transmitted through travelling waves to a region where it is confined in the form of standing waves. Our results can be used for predictive design and reveal an unexpected new application of the classical linear vibration absorber.
