Harmonizing methods for wildlife abundance estimation and pathogen detection in Europe-a questionnaire survey on three selected host-pathogen combinations

__Background:__ The need for wildlife health surveillance as part of disease control in wildlife, domestic animals and humans on the global level is widely recognized. However, the objectives, methods and intensity of existing wildlife health surveillance programs vary greatly among European countries, resulting in a patchwork of data that are difficult to merge and compare. This survey aimed at evaluating the need and potential for data harmonization in wildlife health in Europe. The specific objective was to collect information on methods currently used to estimate host abundance and pathogen prevalence. Questionnaires were designed t

Quality indicators for patients with traumatic brain injury in European intensive care units

Background: The aim of this study is to validate a previously published consensus-based quality indicator set for the management of patients with traumatic brain injury (TBI) at intensive care units (ICUs) in Europe and to study its potential for quality measur

Changing care pathways and between-center practice variations in intensive care for traumatic brain injury across Europe

Purpose: To describe ICU stay, selected management aspects, and outcome of Intensive Care Unit (ICU) patients with traumatic brain injury (TBI) in Europe, and to quantify variation across centers. Methods: This is a prospective observational multicenter study conducted across 18 countries in Europe and Israel. Admission characteristics, clinical data, and outcome were described at patient- and center levels. Between-center variation in the total ICU population was quantified with the median odds ratio (MOR), with correction for case-mix and random variation between centers. Results: A total of 2138 patients were admitted to the ICU, with median age of 49 years; 36% of which were mild TBI (Glasgow Coma Scale; GCS 13–15). Within, 72 h 636 (30%) were discharged and 128 (6%) died. Early deaths and long-stay patients (> 72 h) had more severe injuries based on the GCS and neuroimaging characteristics, compared with short-stay patients. Long-stay patients received more monitoring and were treated at higher intensity, and experienced worse 6-month outcome compared to short-stay patients. Between-center variations were prominent in the proportion of short-stay patients (MOR = 2.3, p < 0.001), use of intracranial pressure (ICP) monitoring (MOR = 2.5, p < 0.001) and aggressive treatme

Variation in Structure and Process of Care in Traumatic Brain Injury: Provider Profiles of European Neurotrauma Centers Participating in the CENTER-TBI Study.

INTRODUCTION: The strength of evidence underpinning care and treatment recommendations in traumatic brain injury (TBI) is low. Comparative effectiveness research (CER) has been proposed as a framework to provide evidence for optimal care for TBI patients. The first step in CER is to map the existing variation. The aim of current study is to quantify variation in general structural and process characteristics among centers participating in the Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) study. METHODS: We designed a set of 11 provider profiling questionnaires with 321 questions about various aspects of TBI care, chosen based on literature and expert opinion. After pilot testing, questionnaires were disseminated to 71 centers from 20 countries participating in the CENTER-TBI study. Reliability of questionnaires was estimated by calculating a concordance rate among 5% duplicate questions. RESULTS: All 71 centers completed the questionnaires. Median concordance rate among duplicate questions was 0.85. The majority of centers were academic hospitals (n = 65, 92%), designated as a level I trauma center (n = 48, 68%) and situated in an urban location (n = 70, 99%). The availability of facilities for neuro-trauma care varied across centers; e.g. 40 (57%) had a dedicated neuro-intensive care unit (ICU), 36 (51%) had an in-hospital rehabilitation unit and the organization of the ICU was closed in 64% (n = 45) of the centers. In addition, we found wide variation in processes of care, such as the ICU admission policy and intracranial pressure monitoring policy among centers. CONCLUSION: Even among high-volume, specialized neurotrauma centers there is substantial variation in structures and processes of TBI care. This variation provides an opportunity to study effectiveness of specific aspects of TBI care and to identify best practices with CER approaches

Machine learning algorithms performed no better than regression models for prognostication in traumatic brain injury

Objective: We aimed to explore the added value of common machine learning (ML) algorithms for prediction of outcome for moderate and severe traumatic brain injury. Study Design and Setting: We performed logistic regression (LR), lasso regression, and ridge regression with key baseline predictors in the IMPACT-II database (15 studies, n = 11,022). ML algorithms included support vector machines, random forests, gradient boosting machines, and artificial neural networks and were trained using the same predictors. To assess generalizability of predictions, we performed internal, internal-external, and external validation on the recent CENTER-TBI study (patients with Glasgow Coma Scale <13, n = 1,554). Both calibration (calibration slope/intercept) and discrimination (area under the curve) was quantified. Results: In the IMPACT-II database, 3,332/11,022 (30%) died and 5,233(48%) had unfavorable outcome (Glasgow Outcome Scale less than 4). In the CENTER-TBI study, 348/1,554(29%) died and 651(54%) had unfavorable outcome. Discrimination and calibration varied widely between the studies and less so between the studied algorithms. The mean area under the curve was 0.82 for mortality and 0.77 for unfavorable outcomes in the CENTER-TBI study. Conclusion: ML algorithms may not outperform traditional regression approaches in a low-dimensional setting for outcome prediction after moderate or severe traumatic brain injury. Similar to regression-based prediction models, ML algorithms should be rigorously validated to ensure applicability to new populations

Search for a light CP -odd Higgs boson in radiative decays of J /&#968;

none406siWe search for a light Higgs boson A0 in the fully reconstructed decay chain of J/ψ→γA0, A0→μ+μ- using (225.0±2.8)×106 J/ψ events collected by the BESIII experiment. The A0 is a hypothetical CP-odd light Higgs boson predicted by many extensions of the Standard Model including two spin-0 doublets plus an extra singlet. We find no evidence for A0 production and set 90% confidence-level upper limits on the product branching fraction B(J/ψ→γA0)×B(A0→μ+μ-) in the range of (2.8-495.3)×10-8 for 0.212≤mA0≤3.0 GeV/c2. The new limits are five times below our previous results, and the nature of the A0 is constrained to be mostly singlet.noneAblikim, M.; Achasov, M.N.; Ai, X.C.; Albayrak, O.; Albrecht, M.; Ambrose, D.J.; Amoroso, A.; An, F.F.; An, Q.; Bai, J.Z.; Baldini Ferroli, R.; Ban, Y.; Bennett, D.W.; Bennett, J.V.; Bertani, M.; Bettoni, D.; Bian, J.M.; Bianchi, F.; Boger, E.; Boyko, I.; Briere, R.A.; Cai, H.; Cai, X.; Cakir, O.; Calcaterra, A.; Cao, G.F.; Cetin, S.A.; Chang, J.F.; Chelkov, G.; Chen, G.; Chen, H.S.; Chen, H.Y.; Chen, J.C.; Chen, M.L.; Chen, S.J.; Chen, X.; Chen, X.R.; Chen, Y.B.; Cheng, H.P.; Chu, X.K.; Cibinetto, G.; Dai, H.L.; Dai, J.P.; Dbeyssi, A.; Dedovich, D.; Deng, Z.Y.; Denig, A.; Denysenko, I.; Destefanis, M.; De Mori, F.; Ding, Y.; Dong, C.; Dong, J.; Dong, L.Y.; Dong, M.Y.; Dou, Z.L.; Du, S.X.; Duan, P.F.; Fan, J.Z.; Fang, J.; Fang, S.S.; Fang, X.; Fang, Y.; Fava, L.; Feldbauer, F.; Felici, G.; Feng, C.Q.; Fioravanti, E.; Fritsch, M.; Fu, C.D.; Gao, Q.; Gao, X.L.; Gao, X.Y.; Gao, Y.; Gao, Z.; Garzia, I.; Goetzen, K.; Gong, W.X.; Gradl, W.; Greco, M.; Gu, M.H.; Gu, Y.T.; Guan, Y.H.; Guo, A.Q.; Guo, L.B.; Guo, Y.; Guo, Y.P.; Haddadi, Z.; Hafner, A.; Han, S.; Harris, F.A.; He, K.L.; Held, T.; Heng, Y.K.; Hou, Z.L.; Hu, C.; Hu, H.M.; Hu, J.F.; Hu, T.; Hu, Y.; Huang, G.M.; Huang, G.S.; Huang, J.S.; Huang, X.T.; Huang, Y.; Hussain, T.; Ji, Q.; Ji, Q.P.; Ji, X.B.; Ji, X.L.; Jiang, L.W.; Jiang, X.S.; Jiang, X.Y.; Jiao, J.B.; Jiao, Z.; Jin, D.P.; Jin, S.; Johansson, T.; Julin, A.; Kalantar-Nayestanaki, N.; Kang, X.L.; Kang, X.S.; Kavatsyuk, M.; Ke, B.C.; Kiese, P.; Kliemt, R.; Kloss, B.; Kolcu, O.B.; Kopf, B.; Kornicer, M.; Kühn, W.; Kupsc, A.; Lange, J.S.; Lara, M.; Larin, P.; Leng, C.; Li, C.; Li, Cheng; Li, D.M.; Li, F.; Li, F.Y.; Li, G.; Li, H.B.; Li, J.C.; Li, Jin; Li, K.; Li, K.; Li, Lei; Li, P.R.; Li, T.; Li, W.D.; Li, W.G.; Li, X.L.; Li, X.M.; Li, X.N.; Li, X.Q.; Li, Z.B.; Liang, H.; Liang, Y.F.; Liang, Y.T.; Liao, G.R.; Lin, D.X.; Liu, B.J.; Liu, C.X.; Liu, D.; Liu, F.H.; Liu, Fang; Liu, Feng; Liu, H.B.; Liu, H.H.; Liu, H.H.; Liu, H.M.; Liu, J.; Liu, J.B.; Liu, J.P.; Liu, J.Y.; Liu, K.; Liu, K.Y.; Liu, L.D.; Liu, P.L.; Liu, Q.; Liu, S.B.; Liu, X.; Liu, Y.B.; Liu, Z.A.; Liu, Zhiqing; Loehner, H.; Lou, X.C.; Lu, H.J.; Lu, J.G.; Lu, Y.; Lu, Y.P.; Luo, C.L.; Luo, M.X.; Luo, T.; Luo, X.L.; Lyu, X.R.; Ma, F.C.; Ma, H.L.; Ma, L.L.; Ma, Q.M.; Ma, T.; Ma, X.N.; Ma, X.Y.; Maas, F.E.; Maggiora, M.; Mao, Y.J.; Mao, Z.P.; Marcello, S.; Messchendorp, J.G.; Min, J.; Mitchell, R.E.; Mo, X.H.; Mo, Y.J.; Morales Morales, C.; Muchnoi, N.
