Measurement of Electron-Neutrino Charged-Current Cross Sections on

Using an 185-kg NaI[Tl] array, COHERENT has measured the inclusive electron-neutrino charged-current cross section on ^{127}I with pion decay-at-rest neutrinos produced by the Spallation Neutron Source at Oak Ridge National Laboratory. Iodine is one the heaviest targets for which low-energy (≤50 MeV) inelastic neutrino-nucleus processes have been measured, and this is the first measurement of its inclusive cross section. After a five-year detector exposure, COHERENT reports a flux-averaged cross section for electron neutrinos of 9.2_{-1.8}^{+2.1}×10^{-40} cm^{2}. This corresponds to a value that is ∼41% lower than predicted using the MARLEY event generator with a measured Gamow-Teller strength distribution. In addition, the observed visible spectrum from charged-current scattering on ^{127}I has been measured between 10 and 55 MeV, and the exclusive zero-neutron and one-or-more-neutron emission cross sections are measured to be 5.2_{-3.1}^{+3.4}×10^{-40} and 2.2_{-0.5}^{+0.4}×10^{-40} cm^{2}, respectively.

Robot assisted radical prostatectomy in fit older patients compared to a standard population: Clinical characteristics, surgical, oncological and functional outcomes.

INTRODUCTION: To compare robotic assisted radical prostatectomy (RARP) in well-selected older patients with clinically localized prostate cancer, compared to a younger population. Primary endpoint was perioperative outcomes comparison and secondary endpoint were oncological and functional outcomes comparison to a younger population. METHODS: Single tertiary center cohort of consecutive patients treated with RARP (2017-2020) with retrospective analysis. Patients were classified by age in two groups: <75: control group (CG) and ≥75: study group (SG). Patients aged ≥75 had a comprehensive geriatric assessment (CGA) and only patients classified Balducci ≤2 were admitted to surgery. RESULTS: Two hundred and sixty-nine patients were included, 56 in SG and 213 in CG. Median follow-up was 9.8 months. Univariate analysis showed no statistically significant (SS) difference between the groups for patients' characteristics (PSA, digital rectal examination -DRE- and biopsy Gleason Score), perioperative data (operative time, hospitalization length, transfusions rate, immediate complications, Clavien-Dindo complications, 30-days re-interventions and 30-days re-hospitalisation), oncological (TNM, margins, extraprostatic extension, postoperative PSA, BCR, metastases, overall survival -OS- and cancer specific survival -CSS-) and functional outcomes. Median perioperative blood loss was lower in the SG: 200.00 cc IQR [100.00, 300.00] vs 200.00cc IQR [100.00, 400.00] in the CG (P<0.05). A multivariate regression considering age>75, DRE, GS, PSA, cardiovascular history and diabetes showed none of variables associated with early BCR. Limitations are retrospective design, small number of patients and short follow-up. CONCLUSIONS: RARP shows similar perioperative, oncologic and functional outcomes for older patients selected by a CGA when compared to younger patients. The SG shows a minor perioperative bleeding. LEVEL OF EVIDENCE: IV.

First Probe of Sub-GeV Dark Matter beyond the Cosmological Expectation with the COHERENT CsI Detector at the SNS.

The COHERENT Collaboration searched for scalar dark matter particles produced at the Spallation Neutron Source with masses between 1 and 220 MeV/c^{2} using a CsI[Na] scintillation detector sensitive to nuclear recoils above 9 keV_{nr}. No evidence for dark matter is found and we thus place limits on allowed parameter space. With this low-threshold detector, we are sensitive to coherent elastic scattering between dark matter and nuclei. The cross section for this process is orders of magnitude higher than for other processes historically used for accelerator-based direct-detection searches so that our small, 14.6 kg detector significantly improves on past constraints. At peak sensitivity, we reject the flux consistent with the cosmologically observed dark-matter concentration for all coupling constants α_{D}<0.64, assuming a scalar dark-matter particle. We also calculate the sensitivity of future COHERENT detectors to dark-matter signals which will ambitiously test multiple dark-matter spin scenarios.

[Review of parenteral nutrition practices in four university hospital's pharmacies in Auvergne-Rhône-Alpes region]. / État des lieux des pratiques de nutrition parentérale dans quatre pharmacies à usage intérieur de centre hospitalier et universitaire de la région Auvergne-Rhône-Alpes.

OBJECTIVES: To carry out an assessment of parenteral nutrition (PN) practices in hospital pharmacies of the Auvergne-Rhône-Alpes region in order to explore a harmonisation of practices and a collaboration between the different centres. METHODS: Status of practices was carried out on the basis of an observational study inspired by the survey of the General Inspectorate of Social Affairs. It was carried out in Auvergne-Rhône-Alpes region in four university hospital pharmacies with a production unit of PN. It focused on the different stages of the PN process: prescription, formulation, compounding and quality control. It also covered the support processes such as the quality assurance system and the management of premises and equipment. RESULTS: Most preparations made in the region are individualized parenteral nutritional admixtures for paediatric and neonatal hospitalization departments. The production units of PN of each centre are located in premises in compliance with Good Preparation Practices. However, compounding equipment and raw materials used are heterogeneous in the four centres. All centres control the quality of their finished preparations. But, the performance of analytical control is disparate in terms of equipment and specifications. CONCLUSION: This assessment explains the similarities and differences in PN practices between various university hospitals in the Auvergne-Rhône-Alpes region and thus makes possible to provide a collective regional work to harmonise practices.

Measurement of the Coherent Elastic Neutrino-Nucleus Scattering Cross Section on CsI by COHERENT.

We measured the cross section of coherent elastic neutrino-nucleus scattering (CEvNS) using a CsI[Na] scintillating crystal in a high flux of neutrinos produced at the Spallation Neutron Source at Oak Ridge National Laboratory. New data collected before detector decommissioning have more than doubled the dataset since the first observation of CEvNS, achieved with this detector. Systematic uncertainties have also been reduced with an updated quenching model, allowing for improved precision. With these analysis improvements, the COHERENT Collaboration determined the cross section to be (165_{-25}^{+30})×10^{-40} cm^{2}, consistent with the standard model, giving the most precise measurement of CEvNS yet. The timing structure of the neutrino beam has been exploited to compare the CEvNS cross section from scattering of different neutrino flavors. This result places leading constraints on neutrino nonstandard interactions while testing lepton flavor universality and measures the weak mixing angle as sin^{2}θ_{W}=0.220_{-0.026}^{+0.028} at Q^{2}≈(50 MeV)^{2}.

A pilot study investigating the feasibility of using a fully automatic software to assess the RENAL and PADUA score.

PURPOSE: Image-based morphometric scoring systems such as the RENAL and PADUA scores are useful to evaluate the complexity of partial nephrectomy for renal cell carcinoma (RCC). The main aim of this study was to develop a new imaging software to enable an automatic detection and a 3D visualization of RCC from CT angiography (CTA) and to address the feasibility to use it to evaluate the features of the RENAL and the PADUA scores. METHODS: A training dataset of 210 patients CTA-scans manually segmented was used to train a deep learning algorithm to develop the automatic detection and 3D-visualization of RCC. A trained operator blindly assessed the RENAL and PADUA scores on a testing dataset of 41 CTA from patients with RCC using a commercialized semi-automatic software (ground truth) and the new automatic software. Concordance between the two methods was evaluated. RESULTS: The median PADUA score was 9 (7-11) and the renal score was 8 (5.5-9). The automatic software enabled to automatically detect the tumoral kidney and provided a 3D-visualization in all cases, with a computational time less than 20 seconds. Concordances for staging the anatomical features of the RENAL scores were respectively: 87.8% for radius, 85.4% for exophytic rate, 82.9% for location to the polar lines and 92.7% for the antero-posterior location. For the PADUA scores, concordances were 90.2% for tumor size, 85.4% for exophytic rate, 87.8% for polar location and 100% for renal rim. CONCLUSION: By enabling an automatic 3D-visualization of tumoral kidney, this software could help to calculate morphometric scores, save time and improve reproducibility for clinicians.

[Medico-economic evaluation of the impact of measures to adapt to the switch to surgery robot-assisted in urology]. / Évaluation médico-economique de l'impact de mesures d'adaptation au virage de la chirurgie robot-assistée en urologie.

INTRODUCTION: The development of robot-assisted urological surgery is held back by the lack of robust medico-economic analyses and their heterogeneity. We conducted a medico-economic study to evaluate the implementation of measures to optimize the transition to robotic surgery. METHOD: We carried out a single-center, controlled study from the point of view of the public healthcare establishment for 4 years. Economic data collection was based on a micro-costing method and revenues from stay-related groups. Clinical data corresponded to mean lengths of stay, operating duration, complications and stays in intensive care. The measures to optimize the transition to robotic, implemented mid-study period, enabled before/after comparison. RESULTS: Altogether, 668 patients undergoing robotic surgery were included. Robotic activity increased significantly from periods 1 to 2 to 256% (P=<0.001) as did the overall proportion of robotic by 45% to 85% (P=<0.001). The mean lengths of stay fell significantly, 6.8 d vs. 5.1 d (P<0.001). Costs and revenues increased significantly, resulting in a persistent deficit for the activity €226K vs. €382K (P=<0.001). With increased volume of activity, the deficit per operation and the cost per minute of robotic operating room fell significantly, €3,284 vs. €1,474/procedure (P=<0.001) and €27 vs €24/min (P=<0.029), tending towards a break-even point (=zero deficit) at 430 operations per year. CONCLUSIONS: Robotic-assisted surgery can be significantly optimized by implementing measures for the robotic turn to reach a break-even point at 430 operations per year. A better multidisciplinary case mix could lower the break-even volume of activity in short term. LEVEL OF EVIDENCE: 3.

Shared decision-making interventions: An overview and a meta-analysis of their impact on vaccine uptake.

BACKGROUND: The interest in shared decision making (SDM) and the use of patient decision aids have increased significantly. Research indicates that this approach has benefits, and yet, implementation remains a challenge. To illustrate this development, we focus on vaccine hesitancy which has become a serious public health challenge during the COVID-19 pandemic. Various strategies have been used in healthcare, with limited success, to help patients overcome vaccine hesitancy. It is unclear whether SDM interventions can increase vaccination rates. AIMS: Our aim was two-fold: to provide an overview of SDM and the use of patient decision aids and to determine the effect of SDM interventions on vaccine uptake. METHODS: To provide an overview, we drew on our knowledge of the field and summarized the most recent systematic reviews. We examined the impact on vaccine hesitancy by searching for randomized controlled trials (RCTs) of SDM interventions, conducted a meta-analysis and calculated a pooled odds ratio. Additional outcomes were reported in a narrative synthesis. RESULTS: SDM is viewed as the pinnacle of patient-centred care, supported by an ethical imperative and by empirical evidence of benefits. We found 10 RCTs that met our inclusion criteria. SDM interventions significantly increased vaccine uptake compared to control groups (odds ratio = 1.45; 95% confidence interval [1.17-1.80]; p < 0.01). Some RCTs also reported significantly decreased decisional conflict and increased decision confidence. CONCLUSION: Future healthcare delivery systems will need to consider how to support the implementation of SDM. Interventions designed to facilitate this approach can represent a helpful, ethically defensible, strategy to increase vaccination rates.

Surgery under COVID: An observational study.

AIM: To evaluate the surgery program strategy adopted in an adult otorhinolaryngology and head and neck surgery department in an area badly affected by the Covid-19 epidemic peak. The main objective was to analyze the reasons for not cancelling surgeries and the postoperative course of operated patients. The secondary objective was to assess the situation of postponed patients. MATERIAL AND METHODS: A single-center observational study carried out during the COVID-19 period in France included 124 patients scheduled for surgery during the period March 21-May 20, 2020. The number and nature of operations, both performed and postponed, were reviewed. RESULTS: A total of 54.0% patients were operated on during the COVID period and 46.0% were postponed. Operations were maintained in urgent or semi-urgent cases. The operated patients did not show any signs of infection during their hospital stay. A total of 29.8% of postponed patients were lost to follow-up and 49.1% were rescheduled. CONCLUSION: The application of national and international recommendations minimized the risk of loss of chance for operated patients without increasing the risk of contamination. The postponement of canceled operations resulted in considerable loss to follow-up. Intensified follow-up is necessary for these patients.

Auditory performance after cochlear reimplantation.

AIM: The aim of this study was to evaluate the impact of cochlear reimplantation (CR) on hearing performance in children and adults with severe to profound hearing loss. MATERIAL AND METHODS: Retrospective observational study. OBJECTIVES: The main objective of this study was to determine whether there was a difference in hearing performance before and after CR. Secondary objectives were to analyze reasons for CR; to assess correlations between auditory performance and complete electrode reinsertion during CR, age, gender, explantation-to-CR interval, and interval between first implantation and CR; and to assess difference in APCEI score and the French evaluation protocol for implanted patients before and after CR. RESULTS: Comparison of speech perception scores before and after explantation-reimplantation showed no significant difference (P>0.005) at 1 year or at 2 years after CR. In 80% of cases, reimplantation was due to hard implant failure. In other cases, it was undertaken for soft failure (diminished performance but no abnormalities on integrity testing) (8%), medical reasons (6%), or undetermined reasons (6%). There was no significant correlation between auditory performance at 1 or 2 years and complete or incomplete reinsertion of electrodes, age, gender, explantation-to-CR interval, or interval between first implantation and CR (P>0.005). For the adult subgroup, the French evaluation protocol scores did not differ after reimplantation (P=0.62). Likewise, for the child sub-group, APCEI and CAP results did not deteriorate after reimplantation. CONCLUSION: Reimplantation had no negative impact on hearing and speech perception, but provided performance equivalent to or better than after initial implantation.

[Outcomes following the triage of patients for urological cancer and non-cancer surgery during Covid-19 pandemic peak]. / Évaluation des mesures de triages de la première vague pandémique Covid-19 pour sélectionner les patients à opérer pour cancers et urgences urologiques.

INTRODUCTION: Faced with the first wave of Covid-19 pandemic, guidelines for surgical triage were developed to free up healthcare resources. The aim of our study was to assess clinical characteristics and surgical outcomes of triaged patients during the first Covid-19 crisis. METHOD: We conducted a cohort-controlled, non-randomized, study in a University Hospital of south-eastern France. Data were collected prospectively from consecutive patients after triage during the period from March 15th to May 1st and compared with control data from outside pandemic period. Primary endpoint was intensive care unit (ICU) admissions for surgery-related complications. Rates of surgery-specific death, postponed operations, positive PCR testing and Clavien-Dindo complications and data from cancer and non- cancer subgroups were assessed. RESULTS: After triage, 96 of 142 elective surgeries were postponed. Altogether, 71 patients, median age 68 y.o (IQR: 56-75 y.o), sex ratio M/F of 4/1, had surgery, among whom, 48 (68%) had uro-oncological surgery. No patients developed Covid-19 pneumonia in the post-surgery period. Three (4%) were admitted to the ICU, one of whom died from multi-organ failure due to septic shock caused by klebsiella pneumonia following a delay in treatment. Three Covid-19 RT-PCR were done and all were negative. There was no difference in mortality rates or ICU admission rates between control and Covid- era patients. CONCLUSIONS: Surgery after triage during the first Covid-19 pandemic was not associated with worse short-term outcomes. Urological cancers could be operated on safely in our context but delays in care for aggressive genitourinary diseases could be life threatening. LEVEL OF EVIDENCE: 3.

The Anti-inflammatory Effect of the Tricyclic Antidepressant Clomipramine and Its High Penetration in the Brain Might Be Useful to Prevent the Psychiatric Consequences of SARS-CoV-2 Infection.

At the time of writing (December 2020), coronavirus disease 2019 (COVID-19) has already caused more than one million deaths worldwide, and therefore, it is imperative to find effective treatments. The "cytokine storm" induced by Severe Acute Respiratory Syndrome-Coronavirus type 2 (SARS-CoV-2) is a good target to prevent disease worsening, as indicated by the results obtained with tocilizumab and dexamethasone. SARS-CoV-2 can also invade the brain and cause neuro-inflammation with dramatic neurological manifestations, such as viral encephalitis. This could lead to potentially incapacitating long-term consequences, such as the development of psychiatric disorders, as previously observed with SARS-CoV. Several pathways/mechanisms could explain the link between viral infection and development of psychiatric diseases, especially neuro-inflammation induced by SARS-CoV-2. Therefore, it is important to find molecules with anti-inflammatory properties that penetrate easily into the brain. For instance, some antidepressants have anti-inflammatory action and pass easily through the blood brain barrier. Among them, clomipramine has shown very strong anti-inflammatory properties in vitro, in vivo (animal models) and human studies, especially in the brain. The aim of this review is to discuss the potential application of clomipramine to prevent post-infectious mental complications. Repositioning and testing antidepressants for COVID-19 management could help to reduce peripheral and especially central inflammation and to prevent the acute and particularly the long-term consequences of SARS-CoV-2 infection.

Bariatric surgery related proximal myopathy: A partially reversible complication.

Deficiency neuropathies and rhabdomyolysis have previously been reported after bariatric surgery (BS) but never myopathies. We report cases of five patients with morbid obesity who developed within 2 to 4 months of a BS, proximal myopathy following significant and rapid weight loss worsened by postoperative gastrointestinal complications. Muscle weakness concerned lower limbs in particular in quadriceps and less frequently in upper limbs and diaphragm, sometimes mimicked a Guillain-Barré syndrome. Muscle biopsy performed in 1 patient, revealed selective atrophy of type 2 fibers. Weakness slowly decreased with refeeding with vitamins supplementation. We enlarge here the clinical pattern of post-BS complications.

[ECMO for post cardiotomy refractory cardiogenic shock: Experience of the cardiac surgery department of the Grenoble Alpes University Hospital]. / ECMO pour choc cardiogénique réfractaire post cardiotomie : expérience du service de chirurgie cardiaque du CHU de Grenoble Alpes.

OBJECTIVE: The objective of our study is to detail our experience relating to ECMO implantations for post-cardiotomy refractory shock, by analyzing the pre-ECMO factors (history, type of surgery, LVEF), factors relating to ECMO (implantation time, duration) and post-ECMO factors (weaning, complications) in order to highlight those possibly associated with high mortality. METHODS: This is a univariate and multivariate retrospective study of ECMO data implemented between 2011 and 2019 at the Grenoble Alpes University Hospital Center following cardiac surgery. The time to implantation of ECMO was less than 3hours (intraoperative) between 3 and 24hours (early postoperative) and between 24 and 48hours after aortic unclamping (late postoperative). Preoperative or postoperative intra-aortic balloon counterpulsation (CPBIA) could be associated. RESULTS: 114 veino-arterial ECMOs were implanted for refractory cardiogenic shock after 5702 cardiac surgeries (1.9%) with a survival rate of 30.7%. The mean age of the patients was 68.6+- 10.5 years. The implantation of ECMO was performed intraoperatively in 71 patients (62.2%), early postoperatively in 22 patients (19.2%) and late postoperatively in 21 patients (18.4%). The duration of assistance was less than 48hours in 27 patients (23.6%), between 48hours and one week in 58 patients (50.9%) and more than one week in 29 patients (25.5%). Univariate analysis revealed a statistically significant association between mortality rate and male sex (P=0.002), association absent with other preoperative characteristics, delay in implantation of ECMO, installation of CPBIA, post-operative characteristics and resuscitation suites. Multivariate analysis of the entire study population demonstrated that the use of ECMO for cardio-respiratory arrest was the only independent risk factor for mortality (OR=7.57 [1.41-40, 62]). After multivariate reanalysis excluding patients with ECMO placement for cardio respiratory arrest, age, preoperative renal failure, type of procedure and EuroSCORE II were risk factors for mortality. CONCLUSION: In this study, male gender, type of intervention, occurrence of cardiac arrest were significantly associated with the death rate. A study of greater power, multicentric, and with a larger sample, will have to be carried out to reach significance.

Early postoperative bleeding after isolated coronary bypasses: Changes over a period of 20 years - An observational study.

OBJECTIVES: The objectives were to analyze the evolution of the postoperative bleeding after coronary artery bypass grafting and to determine which factors impacted on this evolution. METHODS: This is a single-center retrospective study including 4590 patients undergoing coronary bypass surgery between 1995 and 2017. The study period was divided into 3 same-sized periods. We analyzed the evolution of the bleeding according to: the chest volume bleeding over the first 24hours, the severity and the rate of transfusion during the hospital stay. Intrahospital outcomes were compared between "minor" and "major" bleedings. The risk factors of major bleeding were analyzed by multiple logistic regression. RESULTS: The chest volume decreased particularly during the first years of the study period. Major bleedings decreased over the periods (7.3%, 4.9% and 3.8% respectively, P<0.0001), as did the rate of transfusion (26.4%, 23.5% and 19.6% respectively, P<0.0001). Major bleedings were correlated with hospital mortality (8.2% versus 1.1%, P<0.0001). The risk factors of major bleeding were the period 1 (1995 to 2003), a renal failure, a resternotomy, the EuroSCORE, the hematocrit prior to cardiopulmonary bypass and the duration of cardiopulmonary bypass. CONCLUSIONS: Postoperative bleeding decreased mainly in the 1990s. Progressive changes in bleeding prevention and blood recovery, surgical techniques, haemoglobin threshold for transfusion decision and practitioners' experience have contributed to these results and must be continued to optimize the postoperative outcomes.

First Measurement of Coherent Elastic Neutrino-Nucleus Scattering on Argon.

We report the first measurement of coherent elastic neutrino-nucleus scattering (CEvNS) on argon using a liquid argon detector at the Oak Ridge National Laboratory Spallation Neutron Source. Two independent analyses prefer CEvNS over the background-only null hypothesis with greater than 3σ significance. The measured cross section, averaged over the incident neutrino flux, is (2.2±0.7)×10^{-39} cm^{2}-consistent with the standard model prediction. The neutron-number dependence of this result, together with that from our previous measurement on CsI, confirms the existence of the CEvNS process and provides improved constraints on nonstandard neutrino interactions.

Low dose computed tomography of the lung for detection and grading of interstitial lung disease: A systematic simulation study.

PURPOSE: HRCT is the preferred imaging technique to evaluate Interstitial-Lung-Disease. Optimal Low-Dose-Computed-Tomography protocol for monitoring ILD with lowest radiation dose and optimal diagnostic accuracy and image quality unknown. METHODS: 28 Patients underwent HRCT. Image reconstructions with varying combinations of tube current (50mA, 20mA, 15 mA, 10mA) and image-thickness/increment (1/1mm, 2/2mm, 3/2.4mm, 5/4mm) were simulated from raw data. 448 CTs evaluated by 2 readers on image quality and ILD-specific features (ground glass opacification (ggo), honeycombing (hc), reticulation (ret)). RESULTS: Reduced dose settings with 20 mA did not show any significant difference to standard dose settings for all parameters in reader 1, while results were significantly altered in reader 2. Slice thickness did not significantly influence rating of typical ILD features like ggo, hc, ret or total disease extent. The correct differentiation between UIP and NSIP could be made on all dose settings and with all slice thickness. It was even found, that an increased slice thickness can compensate for the noise associated image quality degradation. Overall, for ggo detection a combination of 20 mA and 3 or 5 mm slice thickness was not different to the original evaluation. CONCLUSIONS: Assessment of ILD specific CT features down to 20 mA and a slice thickness of 3 or 5 mm is feasible.

Determinants of doctors' antibiotic prescriptions for patients over 75 years old in the terminal stage of palliative care.

INTRODUCTION: Notwithstanding high prevalence of presumably bacterial infections in elderly persons (EP) in palliative care (PC), there exists no recommendation on the role of antibiotic therapy (ABP) in this type of situation. OBJECTIVE: To describe the determinants of antibiotic prescription by general practitioners (GP) and by doctors practicing in institutions (DPI) for patients>75 years, in end-of-life situations in PC. METHOD: Descriptive investigation by anonymous self-administered questionnaire disseminated in France by e-mail. RESULTS: A total of 301 questionnaires analyzed: 113 GP, 188 DPIs. The latter were mainly geriatricians (69, 36.6%) and infectologists/internists (41, 21.8%). Sixty-three (55,75%) GPs and 144 (78.7%) DPIs stated that they had prescribed antibiotics. Practice in "EHPAD" retirement homes or intensive care was often associated with non-prescription of antibiotics. Age, PC training and number of patients monitored bore no influence. Family involvement in decision-making was more frequent for GPs than for DPIs. The main purpose of antibiotic therapy was to relieve different symptoms (fever, respiratory congestion, functional urinary signs). Most of the doctors (81%) had previously encountered complications (allergy, adverse effect), which represented the main causes of treatment discontinuation. CONCLUSION: Antibiotic use in end-of-life EPs in PC seems frequent. In accordance with the principle of beneficence, its goal of often symptom-related; that said, in the absence of scientific data, antibiotic prescription in end-of-life situations should be individualized in view of observing the other ethical caregiving principles (beneficence, non-maleficence, justice, patient autonomy) and re-evaluated daily.

[Assessment of a post-emergency pathway with early urological regulation]. / Analyse d'un modèle de circuit court post-urgence avec une régulation précoce urologique.

INTRODUCTION: Urological emergencies represent 7 % of the outpatients at the emergency department (ED). We assessed the effect of setting up a post-emergency consultation (CPU) after deferred urological medical regulation. METHODS: All patients admitted to the ED in a university center over the period December 2017 to July 2018 and for whom a CPU was scheduled were included. The regulation concerned the date of CPU and supplementary exams. The main outcome was the ability to provide an efficient response according to a predefined grid of specific solutions. RESULTS: One hundred and twenty-eight patients were included. The median age was 57 years (18-97). Efficacy of the CPU was 76 %. This rate was lower in no-show patients or consulting for rare and complex motives (47 %, n=60). The no-show were not reachable on the first call in 51.6 % of cases, with a similar age and motives distribution to the others. Only 6,9 % (n=128) of all consultants (n=1863) had been referred to the CPU by emergency physicians. The decision was a second consultation in 70 % (48), a new exam in 10 % (7), deferred emergency surgery in 12 % (8) and finally 18 % (12) of no follow-up. CONCLUSION: CPU following early regulation by a urologist provides an effective response in 76 % of situations. Assessment of "no-shows" helped to identify groups at risk. LEVEL OF EVIDENCE: III.

[Urodynamics: All the nurse needs to know]. / Bilan urodynamique : tout ce que l'infirmier(e) doit savoir.

Urodynamic (UD) is an exam intended to explore the mechanisms underlying lower urinary tract symptoms (LUTS) or urinary incontinence (UI). It involves the measurement of bladder and sphincter pressures using uretrovesical and rectal catheters with pressure transducers, but also the measurement of urinary flow and bladder sensation during filling. UD is far from being systematic in the assessment of LUTS or UI and must seek to tackle a specific clinical or therapeutic question. Thus, history taking, physical examination, voiding diary and questionnaires are essential prerequisites to UD per se. UD steps include a free (unintubated) uroflowmetry, a cystometry, post-void residual measurement±an urethral profilometry, a pressure-flow study or sensitization tests. The pressures are set to zero before to start the study and the validity of the equipment is tested. This control is continued throughout the procedure to ensure the quality of the recording. Any event (e.g., urine leakage, change of position, urgency) is noted during the study. A final report is made by the doctor. The competence of the nurse ensures the reliability, reproducibility and interpretability of the UD study and the nurse's humanity guarantee f an atmosphere as favourable as possible for this uncomfortable and invasive test.
