RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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}.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

OBJECTIVES: To assess whether the initial treatment of non-muscle invasive bladder cancer (NMIBC) was performed according to the guidelines, and to determine the reasons why initial treatment was not provided in nonadherence cases. MATERIALS AND METHODS: We retrospectively reviewed all patients with NMIBC who underwent their first transurethral resection of bladder tumor (TURBT) at a peripheral hospital, between 2007 and 2016. The treatment offered to the patient was compared to the European Association of Urology guidelines according to risk stratification. For each patient who did not receive the treatment according to the guidelines, one of the following reasons was identified: poor patient compliance, poor patient general health status, urologist's decision, lack of resources. RESULTS: One hundred fifty-nine patients were included with a mean age of 72.2 years at the time of NMIBC diagnosis. The low-risk patients were strictly treated according to the guidelines. Among the intermediate-risk patients, 14% received mitomycin C. Among the high-risk patients, 39% received intravesical Bacillus Calmette-Guerin. In the nonadherence cases (61%), the reasons were related to the patient in 44% of cases (poor compliance, 21%; poor patient general health status, 23%), urologist's decision in 54% of cases, and lack of resources in 2% of cases. Thirty-seven percent of the high-risk patients underwent re-resection. CONCLUSIONS: Overall, adherence to NMIBC guidelines was low in all treatment types (intravesical therapy, re-resection, or cystectomy for very high-risk patients), but this finding was similar to that in previous studies. Reasons were mainly related to the urologist's decision or to the patient condition (poor compliance or poor general health status). LEVEL OF EVIDENCE: 3.

RESUMO

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.

RESUMO

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.

RESUMO

We prove that optimal control of light energy storage in disordered media can be reached by wave front shaping. For this purpose, we build an operator for dwell times from the scattering matrix and characterize its full eigenvalue distribution both numerically and analytically in the diffusive regime, where the thickness L of the medium is much larger than the mean free path ℓ. We show that the distribution has a finite support with a maximal dwell time larger than the most likely value by a factor (L/ℓ)^{2}≫1. This reveals that the highest dwell-time eigenstates deposit more energy than the open channels of the medium. Finally, we show that the dwell-time operator can be used to store energy in resonant targets buried in complex media, without any need for guide stars.

RESUMO

BACKGROUND: Head-to-head comparisons of combinations of more than one non-opioid analgesic (NOA) with morphine alone, for postoperative analgesia, are lacking. The objective of this multicentre, randomised, double-blind controlled trial was to compare the morphine-sparing effects of different combinations of three NOAs-paracetamol (P), nefopam (N), and ketoprofen (K)-for postoperative analgesia. METHODS: Patients from 10 hospitals were randomised to one of eight groups: control (C) received saline as placebo, P, N, K, PN, PK, NK, and PNK. Treatments were given intravenously four times a day during the first 48 h after surgery, and morphine patient-controlled analgesia was used as rescue analgesia. The outcome measures were morphine consumption, pain scores, and morphine-related side-effects evaluated 24 and 48 h after surgery. RESULTS: Two hundred and thirty-seven patients undergoing a major surgical procedure were included between July 2013 and November 2016. Despite a failure to reach a calculated sample size, 24 h morphine consumption [median (inter-quartile range)] was significantly reduced in the PNK group [5 (1-11) mg] compared with either the C group [27 (11-42) mg; P<0.05] or the N group [21 (12-29) mg; P<0.05]. Results were similar 48 h after surgery. Patients experienced less pain in the PNK group compared with the C, N, and P groups. No difference was observed in the incidence of morphine-related side-effects. CONCLUSIONS: Combining three NOAs with morphine allows a significant morphine sparing for 48 h after surgery associated with superior analgesia the first 24 h when compared with morphine alone.

RESUMO

Following cardiac surgery, hyperlactatemia due to anaerobic metabolism is associated with an increase in both morbidity and mortality. We previously found that an elevated respiratory quotient (RQ) predicts anaerobic metabolism. In the present study we aimed to demonstrate that it is also associated with poor outcome following cardiac surgery. This single institution, prospective, observational study includes all those patients that were consecutively admitted to the intensive care unit (ICU) after cardiac surgery with cardiopulmonary bypass, that had also been monitored using pulmonary artery catheter. Data were recorded at admission (H0) and after one hour (H1) including: oxygen consumption ([Formula: see text]), carbon dioxide production ([Formula: see text]), RQ ([Formula: see text]), lactate levels and mixed venous oxygen saturation ([Formula: see text]). The primary endpoint was defined as mortality at 30 days. Comparison of the area under the curve (AUC) for receiver operating characteristic curves was used to analyze the prognostic predictive value of RQ, lactate levels and [Formula: see text], in terms of patient outcome. We studied 151 patients admitted to the ICU between May 2015 and February 2016. Seventy eight patients experienced a worse than expected outcome in the post-operative period, and among those seven died. RQ at H1 in non-survivors ([Formula: see text]) was higher than in survivors ([Formula: see text]; p = 0.02). The AUC for RQ to predict mortality was 0.77 (IC95% [0.70-0.84]), with a threshold value of 0.76 (sensitivity 64%, specificity 100%). By comparison, the AUC for lactate levels was significantly superior (AUClact 0.89, IC95% [0.83-0.93], p = 0.02). In this study, elevated RQ appeared to be predictive of mortality after cardiac surgery with CPB.

RESUMO

Aim The aim of this review was to evaluate the efficacy of magnetic resonance imaging (MRI) in determining appendicitis during pregnancy. Methods We retrospectively reviewed the clinical course for all pregnant patients with suspected appendicitis from 2013-2018. We evaluated the efficacy of MRI and Alvarado scoring and its impact on management. Results Twenty-nine pregnant patients with suspected appendicitis had an MRI. The majority (90%, n=26/29) had normal diagnostics with two patients (10.3%) having findings consistent with acute appendicitis. Two other patients proceeded to laparoscopy, one with an inconclusive MRI, and one patient with clinical appendicitis. We found no accurate correlation between pregnancy and Alvarado scoring. Conclusion MRI is a safe adjunct in accurately diagnosing appendicitis in pregnancy. Its routine use could help reduce rates of negative appendectomies and the potential risk to maternal and fetal health.

RESUMO

Secondary surgeries for single craniosynostosis surgeries are mainly esthetic refinements rather than functional indications. However, cranioplasties for bone defects correction or insufficient corrections may be undertaken. Management of syndromic craniosynostoses usually requires multiple surgical interventions, the sequence of which might vary per the genetic mutation. It is commonplace to start with posterior vault expansion before age 6 months, then treat cerebellar tonsillar herniation by the age of twelve months, and delay fronto-facial monobloc advancement until at least 18-24 months of age. Ventricular shunting is preferably avoided or delayed. Failure to respect these guidelines can significantly complicate the subsequent management. Primary fronto-orbital advancement or early facial osteotomy type Le Fort3, may compromise the subsequent fronto-facial monobloc advancement. However, this salvage secondary monobloc may be undertaken in some instances despite previous anterior osteotomies with a higher morbidity.

RESUMO

Background: Local initiatives to reduce alcohol harms are common. One UK approach, Community Alcohol Partnerships (CAPs), involves partnerships between the alcohol industry and local government, focussing on alcohol misuse and anti-social behaviour (ASB) among young people. This study aimed to assess the evidence of effectiveness of CAPs. Methods: We searched CAP websites and documents, and databases, and contacted CAPs to identify evaluations and summarize their findings. We appraised these against four methodological criteria: (i) reporting of pre-post data; (ii) use of comparison area(s); (iii) length of follow-up; and (iv) baseline comparability of comparison and intervention areas. Results: Out of 88 CAPs, we found three CAP evaluations which used controlled designs or comparison areas, and further data on 10 other CAPs. The most robust evaluations found little change in ASB, though few data were presented. While CAPs appear to affect public perceptions of ASB, this is not a measure of the effectiveness of CAPs. Conclusions: Despite industry claims, the few existing evaluations do not provide convincing evidence that CAPs are effective in reducing alcohol harms or ASB. Their main role may be as an alcohol industry corporate social responsibility measure which is intended to limit the reputational damage associated with alcohol-related ASB.
