Statistical characteristics of under-ice noise on the Arctic Chukchi Plateau.

In the context of global warming leading to rapidly changing Arctic sea ice and the environment, it is necessary to understand the statistical characteristics of noise under existing Arctic ocean environmental conditions. The data recorded from August 1, 2018 to November 2, 2019, on the Arctic Chukchi Plateau, have been studied to analyze the relationship between the ice transient events and the non-Gaussian statistics of under-ice noise. The ice-generated transient noise largely contributes to the under-ice noise environment, and the total under-ice noise exhibits non-Gaussian statistics due to the occurrence of these ice transients.

Ocean ambient noise on the Chukchi Plateau and its environmental correlates.

Conducting research on ocean ambient noise under different sea ice conditions is highly important for the comprehension of the rapidly changing Arctic. We present the first results of ambient noise and its relationship to environmental forcing during the open-water, ice transition and ice-covered periods on the Chukchi Plateau. The ambient noise level (ANL) in the 20 Hz to 2 kHz band is higher, intermediate and lower during the open-water, ice transition and ice-covered periods, respectively.

Prognostic Accuracy of qSOFA and SIRS for Mortality in the Emergency Department: A Meta-Analysis and Systematic Review of Prospective Studies.

Objective: This meta-analysis aimed to determine the prognostic performance of quick sequential organ failure assessment (qSOFA) score in comparison to systemic inflammatory response syndrome (SIRS) in predicting in-hospital mortality in the emergency department (ED) patients.

Methods: Eligible studies comparing the performance of qSOFA and SIRS in predicting in-hospital death of ED patients were identified from searching PubMed, Embase, and Cochrane. Raw data were collected, and the pooled sensitivity and specificity were calculated for qSOFA and SIRS.

Baseline assessment of ocean ambient noise in the western Clarion Clipperton Zone, Pacific Ocean.

Ocean noise in the western Clarion Clipperton Zone, Pacific Ocean was recorded for 5 min every hour during 2017 and 2018, at a depth of 300 m. The monthly and hourly mean spectrum levels in the 20-1000 Hz band were calculated, along with their skewness, kurtosis, percentile distributions, and spectral probability densities. The high noise levels at low frequencies generated from distant shipping and vocalizations of whales were found to range between 70 and 100 dB (<100 Hz) and 64-93 dB (100-200 Hz), respectively.

Carbon monoxide poisoning: a prediction model using meteorological factors and air pollutant.

Background: While the influence of meteorology on carbon monoxide (CO) poisoning has been reported, few data are available on the association between air pollutants and the prediction of CO poisoning. Our objective is to explore meteorological and pollutant patterns associated with CO poisoning and to establish a predictive model.

Results: CO poisoning was found to be significantly associated with meteorological and pollutant patterns: low temperatures, low wind speeds, low air concentrations of sulfur dioxide (SO) and ozone (O8h), and high daily temperature changes and ambient CO (r absolute value range: 0.

Prehospital Index provides prognosis for hospitalized patients with acute trauma.

Objective: To evaluate the prognostic value of the Prehospital Index (PHI) for hospitalized patients with acute trauma.

Materials And Methods: PHI score and the Injury Severity Score (ISS) were determined in 1,802 hospitalized patients with acute trauma. Receiver-operator characteristic (ROC) curves were used to compare the PHI and ISS in subgroups, and corresponding prediction indicators were calculated.

The application of a trauma index to assess injury severity and prognosis in hospitalized patients with acute trauma.

Objective: The aim of this study was to determine the application value of a trauma index (TI) to assess condition and likelihood of death in hospitalized patients with acute trauma (AT).

Methods: Trauma index scores and injury severity scores (ISS) were assessed in 1,802 randomly selected cases of AT-hospitalized patients. The receiver operating characteristic (ROC) curve was used to compare the clinical values of TI and ISS values to predict outcomes in AT-hospitalized patients.

Safety of tirofiban for patients with acute ischemic stroke in routine clinical practice.

The aim of the present study was to investigate the safety of tirofiban alone and in combination with various treatments in acute ischemic stroke (AIS). A total of 120 patients with AIS were included in the study, and these patients were divided into three treatment groups: Group A (tirofiban alone, n=68), group B (tirofiban plus thrombolytic therapy, n=26), and group C (tirofiban as a 'bridging therapy', n=26). Risk factors, stroke severity, initial imaging, treatment regimens, complications and long-term outcomes were analyzed.
