Objective. This meta-analysis aimed to determine the prognostic performance of quick sequential organ failure assessment (qSOFA) score in comparison systemic inflammatory response syndrome (SIRS) predicting in-hospital mortality emergency department (ED) patients. Methods. Eligible studies comparing qSOFA and SIRS death ED patients were identified from searching PubMed, Embase, Cochrane. Raw data collected, pooled sensitivity specificity calculated for SIRS. The summary receiver operating...
To evaluate the prognostic value of Prehospital Index (PHI) for hospitalized patients with acute trauma.PHI score and Injury Severity Score (ISS) were determined in 1,802 trauma. Receiver-operator characteristic (ROC) curves used to compare PHI ISS subgroups, corresponding prediction indicators calculated.There significant differences between survival group death (Z=2.674, P=0.007). The area under ROC curve was 0.871 (95% CI 0.855-0.886) 0.792 0.773-0.811) ISS. Optimal cutoff points...
The aim of the present study was to investigate safety tirofiban alone and in combination with various treatments acute ischemic stroke (AIS). A total 120 patients AIS were included study, these divided into three treatment groups: Group (tirofiban alone, n=68), group B plus thrombolytic therapy, n=26), C as a 'bridging therapy', n=26). Risk factors, severity, initial imaging, regimens, complications long‑term outcomes analyzed. In total, eight (6.7%) [six (23.1%) two (7.7%) C] had...
Abstract Background While the influence of meteorology on carbon monoxide (CO) poisoning has been reported, few data are available association between air pollutants and prediction CO poisoning. Our objective is to explore meteorological pollutant patterns associated with establish a predictive model. Results was found be significantly patterns: low temperatures, wind speeds, concentrations sulfur dioxide (SO 2 ) ozone (O 3 8h), high daily temperature changes ambient (r absolute value range:...
In the context of global warming leading to rapidly changing Arctic sea ice and environment, it is necessary understand statistical characteristics noise under existing ocean environmental conditions. The data recorded from August 1, 2018 November 2, 2019, on Chukchi Plateau, have been studied analyze relationship between transient events non-Gaussian statistics under-ice noise. ice-generated largely contributes total exhibits due occurrence these transients. number transients has a strong...
Low-frequency ocean noise (50–500 Hz) was recorded by a single omnidirectional hydrophone in the open waters of Chukchi Plateau from 31 August 2021 to 6 September (local time). After other non-wind interference filtered out, wind-generated source levels (NSLs) were extracted noise. The correlation coefficients between one-third octave NSLs and sea surface wind speed exceed 0.84, an improvement approximately 10% compared those raw data speed. For 200–500 Hz, are highly consistent with...
To obtain a better estimation frequency band for source bearing estimation, experiments using an ice-mounted geophone were performed at three sites on the Arctic ice cap. By transforming to domain, errors of in number bands within 1000 Hz and horizontal peak displacements received by corresponding obtained. After comparing variation same band, it is found that are related displacements, higher displacement values mean smaller errors. When incident angle acoustic thickness meet certain...
Objective To study the utility and feasibility of CRAMS score to assess prognosis patients with acute trauma.Methods A retrospective review 1 802 trauma was conducted calculate ISS score.Receiver operation characteristic curve (ROC) used measure prognostic role in comparison ISS.Results Area under (RUC) 0.885 for (95 ％ CI 0.870-0.900) 0.792 (95％ 0.773-0.811),with statistical difference two scoring systems (Z=4.280,P ＜0.01).To identify potential critical illness,optimal cut-off point was≤7...
Based on the data of Argo float, satellite altimeter merged data, and HYCOM model output, we analyzed temporal-spatial variations a mesoscale cold eddy in east Luzon Strait, used FOR3D to simulate effects this sound propagation, Calculated out transmission loss(TL) with or without eddy.Result show that presence led significant variation propagation.Typically, distances convergence zones were narrowed several kilometers, gain inhibited about 2 dB.
The characteristic of wind-driven ocean ambient noise had been analyzed in the north area Zhongsha island. hydrophone receiving depths is from 155m to 875m. It shown that correlation coefficient between and wind speeds > 0.5 when frequency ≥ 500 Hz non-typhoon periods. decreased with increase depth 250 Hz. this band mainly generated sources near sea surface. In typhoon period, 0.55 it nomadically increased depth. also originated long distances not only local sources. may be deduced traveling...
Argo floats and multi-satellite data were used to analyze the effects of typhoon Usagi (2013) on underwater sound propagation in Eastern Luzon Strait. Results showed that (1) when passed by, sea surface temperature (SST) surrounding areas significantly decreased by ~ 2°C average significant wave height (SWH) increased obviously. The right region track was more influenced, mixed-layer depth from 25 75 m. (2) At source (SD) = 10 m frequency (SF) 1000 Hz, had a great effect whether receiver...
Objective To study the significance and feasibility of modified early warning scores (MEWS) assessing conditions death prediction among pre-hospital acute poisoning patients.Methods We performed a prospective,observational patients between January 1,2010 December 31,2010.Data was collected to calculate MEWS.Numeration data presented in percentage by using chi-square test,and measurement expressed mean with standard deviation,and P ＜ 0.05 considered be different statistical...
Objective To investigate the value of ISS in predicting mortality after multiple trauma.Methods A total 550 patients with trauma treated from March 2007 to May 2011 were divided into survivor group (n =473) and death =77) according outcome.ISS acute physiology chronic health evaluation Ⅱ (APACHE Ⅱ]) used predict patients' risk death.Receiver operation characteristic curve (ROC) was developped compare area under (AUC),optimal cut-off point,and prediction index for two scoring systems.Results...
