The tremendous increase in the growth of misinformation in news articles has the potential threat for the adverse effects on society. Hence, the detection of misinformation in news data has become an appealing research area. The task of annotating and detecting distorted news article sentences is the immediate need in this research direction. Therefore, an attempt has been made to formulate the legitimacy annotation guideline followed by annotation and detection of the legitimacy in Bengali e-papers. The sentence-level manual annotation of Bengali news has been carried out in two levels, namely “Level-1 Shallow Level Classification” and “Level-2 Deep Level Classification” based on semantic properties of Bengali sentences. The tagging of 1,300 anonymous Bengali e-paper sentences has been done using the formulated guideline-based tags for both levels. The validation of the annotation guideline has been done by applying benchmark supervised machine learning algorithms using the lexical feature, syntactic feature, domain-specific feature, and Level-2 specific feature in both levels. Performance evaluation of these classifiers is done in terms of Accuracy, Precision, Recall, and F-Measure. In both levels, Support Vector Machine outperforms other benchmark classifiers with an accuracy of 72% and 65% in Level-1 and Level-2, respectively.

The clinical laboratory in today’s world is a rapidly evolving field which faces a constant pressure to produce quick and reliable results. Sigma metric is a new tool which helps to reduce process variability, quantitate the approximate number of analytical errors, and evaluate and guide for better quality control (QC) practices.To analyze sigma metrics of 16 biochemistry analytes using ERBA XL 200 Biochemistry analyzer, interpret parameter performance, compare analyzer performance with other Middle East studies and modify existing QC practices.This study was undertaken at a clinical laboratory for a period of 12 months from January to December 2020 for the following analytes: albumin (ALB), alanine amino transferase (SGPT), aspartate amino transferase (SGOT), alkaline phosphatase (ALKP), bilirubin total (BIL T), bilirubin direct (BIL D), calcium (CAL), cholesterol (CHOL), creatinine (CREAT), gamma glutamyl transferase (GGT), glucose (GLUC), high density lipoprotein (HDL), triglyceride (TG), total protein (PROT), uric acid (UA) and urea. The Coefficient of variance (CV%) and Bias % were calculated from internal quality control (IQC) and external quality assurance scheme (EQAS) records respectively. Total allowable error (TEa) was obtained using guidelines Clinical Laboratories Improvement Act guidelines (CLIA). Sigma metrics was calculated using CV%, Bias% and TEa for the above parameters. It was found that 5 analytes in level 1 and 8 analytes in level 2 had greater than 6 sigma performance indicating world class quality. Cholesterol, glucose (level 1 and 2) and creatinine level 1 showed >4 sigma performance i.e acceptable performance. Urea (both levels) and GGT (level 1) showed <3 sigma and were therefore identified as the problem analytes. Sigma metrics helps to assess analytic methodologies and can serve as an important self assessment tool for quality assurance in the clinical laboratory. Sigma metric evaluation in this study helped to evaluate the quality of several analytes and also categorize them from high performing to problematic analytes, indicating the utility of this tool. In conclusion, parameters showing lesser than 3 sigma need strict monitoring and modification of quality control procedure with change in method if necessary.

Zusammenfassung Hintergrund Die tatsächliche Anzahl verunglückter E‑Scooter-Fahrer in Deutschland scheint deutlich höher zu sein, als es die aktuellen Zahlen des Statistischen Bundesamtes vermuten lassen. Diese epidemiologische Studie untersucht E‑Scooter-Verletzungen und vergleicht diese mit E‑Bike- und Fahrradverletzungen. Fragestellung Zur Schaffung einer vergleichbaren Datenlage über die Gefahren von E‑Scootern, E‑Bikes und Fahrrädern wurden die typischen Verletzungsmuster analysiert und daraus Präventionsmöglichkeiten abgeleitet. Material und Methode Es wurden alle Patienten, die sich nach Unfällen mit Beteiligung von E‑Scootern, E‑Bikes und Fahrrädern über die universitäre Notaufnahme eines Level-1-Traumazentrums im Zeitraum vom 15. Juni 2019 bis 31. Oktober 2020 vorstellten, prospektiv untersucht. Ergebnisse Es wurden 68 verunglückte E‑Scooter-Fahrer erfasst. Davon waren signifikant mehr männlich als weiblich (p = 0,032). Das mittlere Alter betrug 31,1 (±13) Jahre, und lediglich 11,8 % (n = 8) der Unfälle wurden polizeilich registriert. Im gleichen Zeitraum wurden 34 verunglückte E‑Bike- und 356 Fahrradfahrer erfasst. In allen 3 Gruppen waren die meisten Verletzungen im Kopfbereich, gefolgt von Verletzungen an den oberen Extremitäten. Signifikant mehr E‑Scooter-Fahrer hatten einen ISS ≥ 16 als in der Gruppe der verunglückten Fahrradfahrer (p = 0,016). Verunglückte E‑Scooter-Fahrer hatten eine signifikant längere Krankenhausverweildauer (KHVD) als E‑Bike-Fahrer (p = 0,003) und als Fahrradfahrer (p = 0,001). Einen Helm trugen 52,9 % (n = 18) der E‑Bike- und 53,3 % (n = 113) der Fahrradfahrer, dagegen nur 1,5 % (n = 1) der E‑Scooter-Fahrer. Die häufigste Unfallursache bei E‑Bike- (17,7 %; n = 6) und Fahrradfahrern (10,4 %; n = 37) war das Wegrutschen auf Straßenbahnschienen, bei E‑Scooter-Fahrern die Kollision mit einem Bordstein (7,4 %; n = 5). Diskussion Die 3 untersuchten Patientenkollektive zeigten differierende Verletzungsursachen und -profile. Als Ursachen für einen erhöhten Anteil von Schwerverletzten im Vergleich zu Fahrradfahrern sind die Elektromobilität, Fahren unter Alkoholeinfluss und das unzureichende Tragen eines Helms bei E‑Scootern bei Dominanz von Kopfverletzungen zu nennen. Da 73,5 % (n = 50) der erfassten E‑Scooter-Unfälle nicht polizeilich registriert wurden, ist von einer sehr viel höheren Anzahl von E‑Scooter-Unfällen auszugehen als bisher angenommen. Präventive Maßnahmen könnten die Einführung einer Helmpflicht, eine höhere Anzahl von Verkehrskontrollen, Fahrsicherheitstrainings und der Ausbau von Fahrradwegen sein.

Abstract Current guidelines recommend the use of an intravenous fluid warmer to prevent perioperative hypothermia. Among the various methods of warming intravenous fluids, contact warmers are among the most effective and accurate, particularly in clinical conditions requiring rapid infusions of refrigerated blood or fluids. Contact warmers put the infusate in direct contact with a heating block. Some fluid warmers use heating blocks manufactured from aluminium. Several recent publications, however, have shown that uncoated aluminium blocks can leach potentially toxic amounts of aluminium into the body. In this review we performed a systematic literature review on aluminium leaching with contact fluid warmers and describe what manufacturer and competent authorities did in the past years to ensure patient safety. The search resulted in five articles describing the aluminium leaching. Four different devices (Level 1 Fluid Warmer from Smiths Medical, ThermaCor from Smisson-Cartledge Biomedical, Recirculator 8.0 from Eight Medical International BV, enFlow from Vyaire) were shown to leach high levels of aluminium when heating certain intravenous fluids. One manufacturer (Vyaire) voluntarily removed their product from the market, while three manufacturers (Eight Medical International BV, Smisson-Cartledge Biomedical, and Smiths Medical) revised the instructions for use for the affected devices. The enFlow fluid warmer was subsequently redesigned with a parylene coating over the heating block. The scientific literature shows that by using a thin parylene layer on the heating block, the leaching of aluminium can be nearly eliminated without affecting the heating performance of the device.

Background and Purpose: Pinyin is required in learning Mandarin. The challenge of Romanised Pinyin is that learners must decipher the meaning of words based on the change of tone. Communication research is often conducted without accounting for the effects of the change of tone in learning a language. With the aim of avoiding miscommunication while strengthening awareness, Campus Buddies Programme was employed to provide tone practice for learners and consequently explores the effectiveness of the intervention.   Methodology: This quantitative classroom-based research gathered information through the administration of a questionnaire. The questionnaire was distributed to 32 Mandarin Level 1 learners identified through purposive sampling. The students studied five topics from the syllabus. A total of 10 native speakers who scored A in Sijil Pelajaran Malaysia (SPM) mentored the learners during the programme. The participants were instructed to answer both pre- and post-tests. Part A consists of demographic details, whereas Part B focuses on the effectiveness of questions and Part C consists of 30 questions of content learned by the respondents. The data were then analysed using SPSS 26 software.   Findings: The respondents demonstrated a positive response towards the programme and suggested further improvement ideas such as prolonging the training session and adding more topics and oral activities. The results implicated the programme as a motivator for oral fluency. Many non-native speakers can benefit from conversation with Mandarin native speakers because it is a strong indicator and sound oral mastery strategy.   Contributions: This research provides insights into the effectiveness of the current programme in motivating students’ oral learning. The outcome is essential in determining the Mandarin conversation strategy. More studies adopting different variables are proposed to explore correlations from different perspectives in order to improve students’ oral learning.   Keywords: Tonal pronunciation, native speakers, non-native speakers, foreign language instruction, Mandarin conversation.   Cite as: Chua, N.

Abstract Background: Using Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) during air and ground transport requires coordination among the responding clinical team, transport team, and receiving surgical team. Here, we describe the development of a REBOA transport program in a civilian medical system that demonstrates the value of REBOA as part of the toolkit for safe casualty transport. Methods: The regional REBOA program was developed at St. Anthony Summit Medical Center in a multi-step planning and training process to ensure coordination among the facilities and transport resources during trauma patient care. Retrospective record review was performed on all patients (n=5) that received REBOA for transport from the Level 3 Trauma Center to the Level 1 Trauma Center, since inception of the program in March 2019. Data were gathered from hospital electronic medical records. Results: SASMC has transported five trauma patients under the REBOA program; all successfully arrived at the Level 1 Trauma Center to receive definitive care. The integrated arterial blood pressure monitoring capability in the REBOA catheter provided robust physiologic data to enable data-driven interventions during transport. Conclusion: The REBOA program described here is a model of how REBOA can be used to enable safe transport between levels of care, when, without REBOA, such transport might not be possible. The model is applicable during care of civilian trauma patients and combat casualties, where injured patients are initially treated in a prehospital or Role1/2 environment but require transport to a Level 1 Trauma Center or Role 3+ for definitive care.  Keywords: REBOA, non-compressible hemorrhage, patient transport
