Background
In response to the SARS-CoV-2 epidemic, a convenient, rapid, and sensitive diagnostic method for detecting COVID-19 is crucial for patient control and timely treatment.

Objective
This study aimed to validate the detection of SARS-CoV-2 with the Pluslife SARS-CoV-2 rapid test kit developed based on a novel thermostatic amplification technique called RNase hybridization-assisted amplification.

Methods
From November 25 to December 8, 2022, patients with suspected or confirmed COVID-19, close contacts, and health care workers at high risk of exposure were recruited from 3 hospitals and 1 university. Respiratory specimens were collected for testing with the Pluslife SARS-CoV-2 rapid test kit and compared with reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and a commercial antigen assay kit. Samples from 1447 cases were obtained from 3 “ready-to-test” scenarios in which samples were collected on site and tested immediately, and samples from 503 cases were obtained from a “freeze-thaw test” scenario in which samples were collected, frozen, and thawed for testing.

Results
Pluslife SARS-CoV-2 rapid testing of samples from the “ready-to-test” scenario was found to be accurate (overall sensitivity and specificity of 98.3% and 99.3%, respectively) and diagnostically useful (positive and negative likelihood ratios of 145.45 and 0.02, respectively). Pluslife SARS-CoV-2 rapid testing of samples from the “freeze-thaw test” scenario was also found to be accurate (overall sensitivity and specificity of 71.2% and 98.6%, respectively) and diagnostically useful (positive and negative likelihood ratios of 51.01 and 0.67, respectively). Our findings demonstrated that the time efficiency and accuracy of the results in a “ready-to-test” scenario were better. The time required from sample preparation to the seeing the result of the Pluslife SARS-CoV-2 rapid test was 10 to 38 minutes, which was substantially shorter than that of RT-qPCR (at least 90 minutes). In addition, the diagnostic efficacy of the Pluslife SARS-CoV-2 rapid test was better than that of a commercial antigen assay kit.

Conclusions
The developed RNase hybridization-assisted amplification assay provided rapid, sensitive, and convenient detection of SARS-CoV-2 infection and may be useful for enhanced detection of COVID-19 in homes, high-risk industries, and hospitals.

Experimental Validation of a High-Speed Tracked Vehicle Powertrain Simulation Model
Authors: Ponorac Luka , Blagojević Ivan 
Published: October 2023

Abstract
High-speed tracked vehicles have complex powertrains that, in addition to power transfer and transformation, also perform the functions of vehicle steering and braking systems, as well as power supply system for various subsystems on the vehicle. Analyzing the power balance of a tracked vehicle, especially in specific moving scenarios such as the turning process, is of great importance for understanding the power requirements and workload of the powertrain components and their optimization. A simulation model was developed, based on the construction parameters of an experimentally tested high-speed tracked vehicle to reduce the time and material resources required for experimental testing. Both the simulation and experimental tests were conducted using the same input parameters and driving conditions for different vehicle turning scenarios. Simulation and experimental test results are compared to verify the accuracy of the simulation model. The analysis of the obtained results shows that the average value of the relative rpm error is about 5%, the average value of the relative torque error is about 7%, while the average value of the relative power error is about 6.5%.
Analysis of Heart Pulse Transmission Parameters Determined from Multi-Channel PPG Signals Acquired by a Wearable Optical Sensor
Authors: Přibil Jiří , Přibilová Anna , Frollo Ivan 
Published: October 2023

Abstract
The article describes the development and testing of a special prototype wearable device consisting of three optical photoplethysmography (PPG) sensors. The functionality of the developed triple PPG sensor was tested under normal laboratory conditions and in a running magnetic resonance imaging (MRI) scanner working with a low magnetic field. The results of the first measurements under normal laboratory conditions show that the obtained mutual positions of systolic/diastolic blood pressure values and heart pulse transmission parameters determined from the PPG waves can be fitted by a line segment with a sufficiently high slope. Measurement experiments inside the open-air MRI tomograph show the practical influence of vibrations and acoustic noise on the cardiac system of the examined persons, which was confirmed by a slight increase in the heart pulse rate and changes in pulse transmission time and pulse wave velocity. We plan to perform further measurements inside the whole-body MRI device producing more intensive vibrations and noise with expected higher stress impact on an exposed person.
Those Fighting with Burden on Their Back: Elite Taekwondo Players’ Perfectionism and Fear of Failure
Authors: Alp Ayşegül Funda , Kocaekşi Serdar 
Published: October 2023

Abstract
This study aimed to examine levels of perfectionism and fear of failure of elite athletes in the Turkish national taekwondo team through qualitative research methods. A total of 11 national team athletes (6 females and 5 males) participated in the research. The data were collected using a semi-structured interview technique. In the study, opinions, emotions and thoughts of elite national team athletes about the concept of perfectionism and fear of failure were determined. In the theme of perfectionism, there were 7 categories and 35 codes; in the theme of fear of failure, 6 categories and 36 codes were revealed. It might be concluded that perfectionism and fear of failure have a more complex structure than it seems for elite and high-ranking athletes, and this might affect their motivation in many positive and negative ways. In addition, it was found that when the coach is a family member, two concerns of athletes (the coach is upset due to failure, and the family is upset due to failure) come together. Therefore, those who are both a coach and parent should be more careful with their children/athletes. It should also be kept in mind that while perfectionism is a great source of motivation and self-confidence, it has the potential to make athletes drop out of sports.

Abstract
Air pollution is increasing every year, especially due to the continuous process of industrialization and modernization. In this observational study, we included 38 COPD patients with frequent exacerbating phenotypes and we wanted to see if the values of microparticles with a size of 1.0, 2.5 and 10 μm, recorded in their homes, are above the values recommended by the World Health Organization (WHO). An air quality monitoring source was installed in each patient’s home for at least 24 hr and microparticles with a size of 1.0, 2.5 and 10 μm, temperature, pressure and humidity were measured. MEAN PM2.5 values were higher than the values recommended by the WHO, 25.33 µg/m3 vs. 15 µg/m3. Our analysis showed that the levels of microparticles in the homes of patients with COPD, and frequently exacerbating phenotype, are above the limits recommended by the WHO.
Coexistence of multiple forms of tuberculosis – a delayed diagnosis
Authors: Amalia Militaru Laura , Emanuela Vastag , Cristian Oancea 
Published: October 2023

Abstract

Introduction
Tuberculosis (TB) can be located in any segment of the osteoarticular system, being the most common in the spine, with approximately 50% of cases. In only 10% of the cases of osteoarticular TB the location is multiple; generally, it is monoarticular or located at the level of a single segment of the spine. The diagnosis can be delayed in the early stages due to its varied and hidden presentation and the probability of being confused with other pathologies of the osteoarticular system. Delay in diagnosis can lead to chronic pain, joint destruction and progression to symptomatic bony ankylosis.

Case Presentation
A 64-year-old man presented with left lower limb, coccyx pain and peri-anal discharge. CT scan of the pelvis showed recto-integumentary perianal fistulous trajectory externalised on the left side of the anus and osteomyelitis. Left ankle CT: Cystic image of approximately 4.2/6/10 cm well-demarcated, with some central microcalcifications, located in the postero-tibial soft parts, communicating with the tibiotalar joint.

Conclusion
This case highlights the importance of considering TB as a diagnosis if unusual sites are involved.

Abstract
The impact of COVID-19 on lung function is an indisputable reality that has posed major management problems to all categories of specialists who have treated patients with SARS-CoV-2 infection. This disease presents an impressive multisystemic feature, in correlation with clinical, paraclinical, imaging and functional heterogeneity. Although most COVID-19 cases have a complete resolution, the evolution of vulnerable patients (elderly or people with multiple comorbidities such as cardiovascular, metabolic, renal, neoplastic or respiratory problems) or those with moderate to severe forms of the disease can be slower or even unfavourable. Recent data in the literature have shown that many of these patients return to hospital due to symptoms and respiratory dysfunction more than 6–12 months after the acute viral episode, highlighting the need for rigorous evaluation and further pulmonary function testing among patients with a history of COVID-19 to anticipate the appearance of long-term respiratory functional sequelae.
