Published: March 2021

BACKGROUND

There is still room for improvement in the modified LEMON (look, evaluate, Mallampati, obstruction, neck mobility) criteria for difficult airway prediction and no prediction tool for first-pass success in the emergency department (ED).

OBJECTIVE

We applied modern machine learning approaches to predict difficult airways and first-pass success.

METHODS

In a multicenter prospective study that enrolled consecutive patients who underwent tracheal intubation in 13 EDs, we developed 7 machine learning models (eg, random forest model) using routinely collected data (eg, demographics, initial airway assessment). The outcomes were difficult airway and first-pass success. Model performance was evaluated using c-statistics, calibration slopes, and association measures (eg, sensitivity) in the test set (randomly selected 20% of the data). Their performance was compared with the modified LEMON criteria for difficult airway success and a logistic regression model for first-pass success.

RESULTS

Of 10,741 patients who underwent intubation, 543 patients (5.1%) had a difficult airway, and 7690 patients (71.6%) had first-pass success. In predicting a difficult airway, machine learning models—except for k-point nearest neighbor and multilayer perceptron—had higher discrimination ability than the modified LEMON criteria (all, <i>P</i>≤.001). For example, the ensemble method had the highest c-statistic (0.74 vs 0.62 with the modified LEMON criteria; <i>P</i><.001). Machine learning models—except k-point nearest neighbor and random forest models—had higher discrimination ability for first-pass success. In particular, the ensemble model had the highest c-statistic (0.81 vs 0.76 with the reference regression; <i>P</i><.001).

CONCLUSIONS

Machine learning models demonstrated greater ability for predicting difficult airway and first-pass success in the ED.

Background and objectives
Vitamin D receptor activators and calcimimetics (calcium-sensing receptor agonists) are two major options for medical treatment of secondary hyperparathyroidism. A higher serum calcification propensity (a shorter T50 value) is a novel surrogate marker of calcification stress and mortality in patients with CKD. We tested a hypothesis that a calcimimetic agent etelcalcetide is more effective in increasing T50 value than a vitamin D receptor activator maxacalcitol.

Design, setting, participants, & measurements
A randomized, multicenter, open-label, blinded end point trial with active control was conducted in patients with secondary hyperparathyroidism undergoing hemodialysis in Japan. Patients were randomly assigned to receive intravenous etelcalcetide 5 mg thrice weekly (etelcalcetide group) or intravenous maxacalcitol 5 or 10 µg thrice weekly (maxacalcitol group). The primary, secondary, and tertiary outcomes were changes in T50 value, handgrip strength, and score of the Dementia Assessment Sheet for Community-Based Integrated Care System from baseline to 12 months, respectively.

Results
In total, 425 patients from 23 dialysis centers were screened for eligibility, 326 patients were randomized (etelcalcetide, n=167; control, n=159), and 321 were included in the intention-to-treat analysis (median age, 66 years; 113 women [35%]). The median (interquartile range) of T50 value was changed from 116 minutes (interquartile range, 90–151) to 131 minutes (interquartile range, 102–176) in the maxacalcitol group, whereas it was changed from 123 minutes (interquartile range, 98–174) to 166 minutes (interquartile range, 127–218) in the etelcalcetide group. The increase in T50 value was significantly greater in the etelcalcetide group (difference in change, 20 minutes; 95% confidence interval, 7 to 34 minutes; P=0.004). No significant between-group difference was found in the change in handgrip strength or in the Dementia Assessment Sheet for Community-Based Integrated Care System score.

Conclusions
Etelcalcetide was more effective in increasing T50 value than maxacalcitol among patients on hemodialysis with secondary hyperparathyroidism. There was no difference in handgrip strength or cognition between the two drugs.

Published: March 2021

The main target of the current study is to explain the metacognition of junior high school students with Field Independent (FI) and Field Dependent (FD) cognitive styles in mathematics problem-solving. It should be noted that the statistical population of this study was all junior high school students in the Sragen regency in the 2018/2019 academic year. To reach the research purpose, different instruments such as the cognitive style tests, the problem-solving exercises, and the interview guidance were used. Data analysis was carried out by data collection, data reduction, data presentation, and conclusion. The results indicated that the students who have field-independent cognitive style had high self-confidence that they were able to solve the problem correctly, able to do planning steps, able to make important decisions for themselves, so they can solve the problem properly. Students with FD cognitive style are completely confident that their answer is correct, but they have not yet clarified the steps they need to solve their problems and have not yet focused on their shortcomings in mathematics problem solving, so their task results in mathematics problem-solving incorrectness answer.

Published: March 2021

The usage of the Internet and other related technologies has never been without any consequences. One such consequence is what commonly referred to as cyber aggression, a new form of abusing someone online, which has become a new growing problem in today's society. Cyber aggression offers convenient opportunities to humiliate, bully, or harass another person online. Global studies on cyber aggression found that youths who were aggressed online are reported feeling depressed, anxious, afraid, showing poor academic performance, experiencing eating disorders, and substance abuse usages such as drugs and alcohol. On that account, the study aims to investigate the interrelationships between predictive factors namely peer attachment, parental attachment, exposure to the Internet and cyber aggression-victimization among youths. The renowned general aggression model (GAM) is applied to understand the phenomenon. A sample of 430 urban youths aged between 13 and 18 years living within Klang Valley area were randomly selected to participate in the study. Data were gathered through a self-report questionnaire and later analyzed using SPSS and AMOS. The results revealed several noteworthy findings; the majority of respondents made use of the Internet approximately 7 to 21 hours per day especially during weekends with surfing social media being the major purpose, followed by entertainment and playing online games. A relatively significant number of youths are engaged with cyber victimization through written-verbal and online exclusion. Finally, the structural path analysis indicates that the Internet exposure is the strongest predictor associated with cyber aggression-victimization. Based on these findings, the implications and recommendations for future investigations with reference to the current theoretical framework and empirical findings on cyber aggression-victimization are thoroughly discussed.

An Analysis on the Implementation of Professional Learning Communities in Malaysian Secondary Schools
Authors: Abdull Kareem Omar , Mei Kin Tai 
Published: March 2021

The main objective of the study was to examine the implementation of Professional Learning Communities (PLCs) in Malaysian secondary schools. The study was conducted by using quantitative method whereby a total of 971 principals, senior assistants and teachers were involved in the survey. The descriptive statistical analysis was employed to obtain scores and means whereas the t-test and ANOVA were adopted to test the significance of the concerned variables. The result revealed that, i) the schools were rated as Quite Good in practising PLCs; ii) comparing the two dimensions of PLCs, Organizational Factor achieved a higher mean score than Non-organizational Factor; iii) among all the sub-dimensions, Principals’ Commitment and Support achieved the highest whereas External Support System achieved the lowest mean score. The study summarized that although contextual factors such as decentralized school system, the policy environment and teachers’ workload are potential factors that might impact the development of PLCs, the incompetence of the teachers in practising Collaborative Learning, Collective Inquiry and Reflective Dialogue would significantly hinder their professional practices in PLCs. The study offers an analysis in exploring PLCs towards sustained school improvement and may help move the current available literature to a more coherent, theoretical perspective for practical engagement.

Abstract

OBJECTIVE
To compare soil concentrations of macrolide- and rifampicin-resistant Rhodococcus equi strains (MRRE) on horse-breeding farms that used thoracic ultrasonographic screening (TUS) to identify foals with subclinical pneumonia combined with subsequent administration of macrolides and rifampin to affected foals (TUS farms) versus soil concentrations on farms that did not (non-TUS farms), determine whether the combined use of TUS and antimicrobial treatment of subclinically affected foals was associated with soil concentration of MRRE, and assess whether there were temporal effects on soil concentrations of MRRE during the foaling season.

SAMPLES
720 soil samples and 20 completed questionnaires from 20 horse-breeding farms (10 TUS farms and 10 non-TUS farms) in central Kentucky.

PROCEDURES
A questionnaire was used to gather information from participating farms about their 2019 foaling season. Soil samples were collected during January, March, May, and July 2019 for bacterial culture and antimicrobial susceptibility testing to identify any isolates of MRRE. Results were compared for TUS farms versus non-TUS farms. Linear mixed-effects modeling was used to evaluate for potential associations between the soil concentration of MRRE and the use of TUS.

RESULTS
Overall, the sum of the mean soil concentrations of MRRE was significantly higher for TUS farms (8.85 log10-transformed CFUs/g) versus non-TUS farms (7.37 log10-transformed CFUs/g).

CONCLUSIONS AND CLINICAL RELEVANCE
Our findings indicated that farms that use TUS to identify foals with subclinical pneumonia for antimicrobial treatment select for antimicrobial-resistant R equi strains. Because prognosis is worse for foals infected with resistant versus nonresistant strains of R equi, prudent use of antimicrobials to treat foals with subclinical pulmonary lesions attributed to R equi is recommended.
Clinical features, treatment, and outcome of aural hematomas in horses: 7 cases (2008–2019)
Authors: Boorman Sophie , Boone Lindsey H. , White Amelia 
Published: March 2021

Abstract

OBJECTIVE
To characterize the clinical features, treatment, and outcome of aural hematomas in horses.

ANIMALS
7 horses with 1 or 2 aural hematomas (8 ears in total) treated at a veterinary teaching hospital in 2008 through 2019.

PROCEDURES
Data retrieved from medical records included signalment, pertinent historical information, clinical signs, diagnostic procedures (including dermatologic assessment), and treatments. Case outcome was determined from documentation in the medical record or via telephone communication with owners or referring veterinarians.

RESULTS
3 horses were presented after recurrence of aural hematoma following treatment by the referring veterinarian. Four horses had a history of allergic skin disease prior to aural hematoma development. Most (6/7) horses were unilaterally affected. Diagnostic assessments included otoscopic evaluation (3 horses), ultrasonography (3 horses), cytologic examination of ear canal swab samples (3 horses), and histologic examination of a pinnal biopsy specimen (1 horse). Of the 8 pinnae, 2 were treated by nonsurgical needle drainage (1 with concurrent corticosteroid injection) and the remaining 6 underwent surgical incision and placement of compressive sutures. Follow-up information was available for 6 horses, and all affected pinnae were fibrotic with 4 horses having permanent drooping of the pinna. One horse developed a hematoma in the contralateral pinna 1 year after hospital discharge.

CONCLUSIONS AND CLINICAL RELEVANCE
Equine aural hematoma is a rare condition. The main principle of treatment is drainage, and treatment options commonly used in small animal practice can be successfully applied in horses. Permanent changes in the cosmetic appearance of the pinna are likely to develop owing to secondary fibrosis.
The usefulness of temporary balloon occlusion during transarterial embolization for scalp arteriovenous fistula
Authors: Kawano Dai , Fukuda Kenji , Fukumoto Hironori , Horio Yoshinobu , Takahara Masaki , Abe Hiroshi , Higashi Toshio , Inoue Tooru 
Published: March 2021

Background:
We present two cases of scalp arteriovenous fistula (sAVF) treated by transarterial embolization with the aid of a temporary balloon occlusion (TBO) to detect precise vasculature.

Case Description:
Case 1: A 59-year-old woman noticed a sudden onset of pulsating bruits. sAVF was fed by the right superficial temporal artery (STA) and drained to the right superficial temporal vein. We performed feeder occlusion using coils after the recognition of a single feeder and a single fistula using TBO. Case 2: A 42-year-old woman noticed a pulsating subcutaneous mass. sAVF was fed by the right occipital artery (OA) and drained to the right occipital vein (OV). We could detect another feeder of the right STA after the TBO of the OA. We performed transarterial feeder occlusion for STA and OA using coil and N-butyl-2-cyanoacrylat including OV and shunt point, because this case was a single fistula with multiple feeders.

Conclusion:
sAVFs are a relatively rare disease with a complex vascular structure. For the adequate transarterial approach, TBO was useful for detecting the precise vasculature of sAVF.

TESTIMONIAL IN (NEW) MEDIA
Authors:   Rzeszów University, Majchrowska Justyna 
Published: March 2021

The linguistic research of (the new) media so far has mainly focused on the analysis of content from broadcasters – people publishing on the Internet in order to convince the potential recipients to enter the website, read articles, explore the website as well as return after leaving it – in exchange for the material or financial benefit. Several years of observation of a variety of text types existing in the media shows that not only texts from broadcasters make it possible to notice and maintain this attention of recipients. Nowadays, similarly as in marketing and advertising, in the media (but not only there) the essential and productive content comes from the recipient. The subject of this quantitative and qualitative linguistic analysis is the title testimonial as a rapidly growing persuasive (promotional) trend in (new) media and a response to the challenges of the modern society.
