ABSTRACT

Aim: Secondary spontaneous pneumothorax is caused by underlying lung disease, while barotraumatic pneumothorax results from mechanical ventilation. SARS-CoV2 (COVID-19) is a disease that is transmitted through droplets and affects many organs such as the lungs, brain, kidney, and liver. The lungs are the most affected organ and have the greatest influence on mortality. In SARS-CoV2 infection, progression of consolidations and expansion towards the upper lobes, the development of pleural or pericardial fluid, the development of lymphadenopathy, the presence of bronchiectasis, the development of cavitation, and pneumothorax are poor prognostic factors. In our study, we aimed to compare factors contributing to the development of pneumothorax in 29 patients who developed pneumothorax during the treatment of COVID-19 infection and follow-up.Material and Methods: Age, gender, habits, co-morbid diseases, clinical, radiological, laboratory, treatment, mortality and morbidity results of 29 patients who developed pneumothorax during the treatment and follow-up of COVID-19 infection were evaluated. Patients were divided into two groups as deceased (Group1) and surviving (Group 2) patients. The results of the groups were compared.Results: We found that mean age, lymphocyte elevation, mechanical ventilator applications, length of stay in the intensive care unit, and complication development after thoracostomy were more significant in Group 1 than in Group 2 (p<0.05), whereas gender, pneumothorax localization, blood group, Rh differences, and smoking were not significant (p>0.05).Discussion: Although the number and ratio of the comparison criteria included in the study were in favor of Group 1, certain parameters were statistically significant. However, the development of pneumothorax is an important cause of mortality in SARS-CoV2 patients.

ABSTRACT

Face masks are commonly used to protect an individual's respiratory system from inhaling fine particulate matter (PM2.5) in polluted air, as well as the airborne pathogens, especially during the ongoing coronavirus disease 2019 (COVID-19) pandemic. However, all conventional masks with anti-PM2.5 function suffer from insufficient facial thermal comfort, particularly in a hot and humid environment. Herein, we demonstrated a novel infrared-transmittance visible-opaque PM2.5 media for radiative cooling utilizing rutile titanium dioxide particle-embedded polyamide 6 (PA6-TiO2). The transmission of visible light and infrared and PM2.5 removal performance of composite media containing a variety of microstructures, such as TiO2 particles of varying sizes, shapes, and contents, were numerically examined to determine the optimal ranges. Then the PA6-TiO2 media was effectively electrospun by controlling the arrangement of fibers and the morphology of TiO2 particles. By transmitting more than 85% of the thermal radiation from the human body and selectively blocking solar irradiance, the developed PA6-TiO2(flower-shaped) media cooled the simulative skin by 10.3°C as compared with commercial masks under strong solar irradiance. Additionally, they demonstrated a high PM2.5 removal efficiency of 95.3%, a low air resistance of 22.5 Pa (at 5.3 cm/s), and a sound water vapor transmission rate of 0.0169 g cm−2 h−1. This study presents an effective strategy for making thermally comfortable anti-PM2.5 masks, which will significantly benefit the public health prevention and control. © The Author(s) 2022.

ABSTRACT

One of the diseases still suffered by many Indonesian people, especially in the city of Depok, is respiratory disease. Currently, respiratory tract disease is a case with a high number of sufferers. An effort to handle these cases is to provide counseling and education for the community. This education aims to enable people to apply a healthy lifestyle independently and prevent various types of diseases. During the COVID-19 pandemic, this role was somewhat difficult to carry out due to limited movement and space. As a solution to this problem, the part of information technology is crucial. One is utilizing multimedia technology as a medium for health education for the community, namely animation. Animation can describe and visualize something so that information can be presented clearly and visually. This study aims to develop animation as a medium of health education for the community, especially in respiratory health. The animation video was generated using the MDLC (Multimedia Development Life Cycle) method. The resulting animated video can inform the public about health that focuses on the health of the respiratory system. 85 % of users stated that this animated video helps them to understand the material presented. © 2022 IEEE.

ABSTRACT

In the context of the COVID-19, respiratory diseases have become the focus of social attention, and the elderly, as a susceptible population, is more significantly affected by the epidemic. In order to fully protect the respiratory system of the elderly and enhance their satisfaction with the function of smart products, this study proposes a design method for smart health care product based on the cognitive behavior of elderly users. Firstly, the user demand gap is explored and determined by using the A-Kano model;secondly, a functional model is created based on the FAST functional theory. After converting the user demand into function, and then the TRIZ theory is applied to choose to use 40 invention principles and 39 general engineering parameters to analyze the problem and get conflict domain solutions, so as to filter out the most ideal solution and innovate its function;Finally, by the design and practice of the smart health care air purification product, its purification range, monitoring data and wearing method will be effectively optimized, and the feasibility of the design solution will be verified by the user interaction satisfaction questionnaire. The study provides new ideas for the design of smart health care products and the solutions of contradictory problems, which would also be a theoretical guidance for relevant designer and researchers. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

ABSTRACT

The World Health Organization (WHO) declared the coronavirus accession as a global pandemic on 11th March 2020. COVID-19 infection outcrops in all age groups, and children might be less probably to become infected or, if infected, may show milder signs. We searched MEDLINE via PubMed, Scopus, Web of Science Core Collection (WoS), Science Direct, Google Scholar (as English databases);Magiran, Iran Medex, Iran Doc, and SID (as Persian databases). In this study, more than 80 publications from December 2019 to mid-September 2020 were reviewed with the most relevant papers about COVID-19 in children. According to the latest reports of previous studies treatmentd in Iran, the average age of children with COVID-19 infection has been reported as ranging from less than 4 months to 15 years. Also, most reported cases were males. Death in this age group was rare, but it can simply occur in children with severe conditions. The all over course of sickness, mainly pulmonary involvement- of the infected children tend to be milder compared to adults. Laboratory tests and computed tomography (CT) scan findings were nonspecific and milder compared to those at older ages. It should be noted that there is no specific passd medication for treatment of COVID-19-infected children. According to recent reports, COVID-19 characteristicss in children are not yet fully understood, which poses a remarkable problem for children's medical specialists. It should be considered that most children are asignatic or have mild signs and signs.

ABSTRACT

Covid-19 is a disease caused by a new type of coronavirus, namely SARS-CoV-2 (Severe Acute Respiratory Syndrome-Coronavirus-2). Covid-19 attacks humans in the respiratory system ranging from mild flu-like symptoms, to lung infections such as Covid-19 pneumonia spreads very quickly, namely through droplets, aerosols, etc. which are not visible to the naked eye. With these conditions, so an innovation is needed to prevent and overcome it with UVD robots. UVD Robot (Ultraviolet Disinfection Robot) is a robot that can disinfect viruses in a room with UVC light. UVD Robot Robot can be controlled automatically or manually so that it can be controlled from several meters. UVC (Ultraviolet C) light with a wavelength of 254 nm has the ability to prevent viral replication at the appropriate dose, distance, and time. The way UVC light works is to damage the structure of the DNA and RNA viruses so that they cannot replicate themselves. This research is based on the speed and trajectory of the UVD robot in order to obtain an effective configuration without reducing the ability of the UVD robot.

ABSTRACT

Virus, bacteria and fungi are the most common causes for spreading illness in human and in animals. These are the microorganisms and they can cause epidemic and pandemic diseases. World is passing through many viral epidemics affecting respiratory system since last twenty years. It includes SARS-CoV 2002-2003, H1N1 Influenza 2009, MERS-CoV 2012 to the recent COVID-2019. COVID-19 is a viral pandemic infection this is air borne illness that is spreading through droplet infection. This virus especially affects the respiratory system by doing immunosuppression in person. In Ayurveda there are references of Janapadodhwamsa in Charaka samhita vimansthan. Janapadodhwamsa – is the term coined by Charak which means destruction of population living in same place at the same time because of 4 main reasons i.e. Dushit vayu (Air), Dushit jala (water), Dushit desh (land), Dushit kaal (time) Janapadodhwamsha causes death of individuals in the affected area inflicting huge destruction.

ABSTRACT

The 2019 Coronavirus (COVID-19) virus has caused damage on people's respiratory systems over the world. Computed Tomography (CT) is a faster complement for RT-PCR during peak virus spread times. Nowadays, Deep Learning (DL) with CT provides more robust and reliable methods for classifying patterns in medical pictures. In this paper, we proposed a simple low training proposed customized Convolutional Neural Networks (CNN) customized model based on CNN architecture that layers which are optionals may be included such as the layer of batch normalization to reduce time taken for training and a layer with a dropout to deal with overfitting. We employed a huge dataset of chest CT slices images from diverse sources COVIDx-CT, which consists of a 16,146-image dataset with 810 patients of various nationalities. The proposed customized model's classification results compared to the VGG-16, Alex Net, and ResNet50 Deep Learning models. The proposed CNN model shows robustness by achieving an overall accuracy of 93% compared to 88%, 89%, and 95% for the VGG-16, Alex Net, and ResNet50 DL models for the classification of 3 classes. When this relates to binary classification, the classification accuracy of the proposed model and the VGG-16 models were identical (almost 100% accurate), with 0.17% of misclassification in the class of Non-Covid-19, the Alex Net model achieved almost 100% classification accuracy with 0.33% misclassification in the class of Non-Covid-19. Finally, ResNet50 achieved 95% classification accuracy with 5% misclassification in the Non-Covid-19 class. © The Author(s).

ABSTRACT

A novel coronavirus disease (COVID-19) has been a severe world threat to humans since December 2020. The virus mainly affects the human respiratory system, making breathing difficult. Early detection and Diagnosis are essential to controlling the disease. Radiological imaging, like Computed Tomography (CT) scans, produces clear, high-quality chest images and helps quickly diagnoses lung abnormalities. The recent advancements in Artificial intelligence enable accurate and fast detection of COVID-19 symptoms on chest CT images. This paper presents COVIDnet, an improved and efficient deep learning Model for COVID-19 diagnosis on chest CT images. We developed a chest CT dataset from 220 CT studies from Tamil Nadu, India, to evaluate the proposed model. The final dataset contains 5191 CT images (3820 COVID-infected and 1371 normal CT images). The proposed COVIDnet model aims to produce accurate diagnostics for classifying these two classes. Our experimental result shows that COVIDnet achieved a superior accuracy of 98.98% when compared with three contemporary deep learning models. © 2022,International Journal of Advanced Computer Science and Applications.

ABSTRACT

ObjectiveTo describe the incidence and burden of illness at the Tokyo 2020 Paralympic Games, which was organised with strict COVID-19 countermeasures.MethodsDaily illnesses were recorded via the web-based injury and illness surveillance system (teams with their own medical staff;n=81), and local polyclinic services (teams without their own medical staff;n=81). Illness proportion, incidence and burden were reported for all illnesses and in subgroups by sex, age, competition period, sports and physiological system.Results4403 athletes (1853 female and 2550 male) from 162 countries were monitored for the 15-day period of the Tokyo Paralympic Games (66 045 athlete days). The overall incidence of illnesses per 1000 athlete days was 4.2 (95% CI 3.8 to 4.8;280 illnesses). The highest incidences were in wheelchair tennis (7.1), shooting (6.1) and the new sport of badminton (5.9). A higher incidence was observed in female compared with male athletes (5.1 vs 3.6;p=0.005), as well as during the precompetition versus competition period (7.0 vs 3.5;p<0.0001). Dermatological and respiratory illnesses had the highest incidence (1.1 and 0.8, respectively). Illness burden was 4.9 days per 1000 athlete days and 23% of illnesses resulted in time loss from training/competition>1 day.ConclusionThe incidence of illness at the Tokyo 2020 Paralympic Games was the lowest yet to be recorded in either the summer or winter Paralympic Games. Dermatological and respiratory illnesses were the most common, with the burden of respiratory illness being the highest, largely due to time loss associated with COVID-19 cases. Infection countermeasures appeared successful in reducing respiratory and overall illness, suggesting implementation in future Paralympic Games may mitigate illness risk.

ABSTRACT

- Covid-19 is an infectious disease that attacks the respiratory system caused by the coronavirus found in 2019. It has a deadly infection and rapid spread worldwide without exception in Indonesia. Then since the year, World Health Organization (WHO) has declared it a world pandemic. One way to prevent the spread of Covid-19, especially in the closed public area, is by spraying disinfectant to kill the virus. In this project, a low-end disinfectant sprayer has been built based on an Arduino system. The sprayer has been applied to a 10.3mx7.8m classroom with 30 units of the misting device. Performance test of the system shows that the sprayer can work accurately at the timetable to spray the classroom by consuming 58.31 W in operation and 19.80W in standby mode. The total hardware implementation cost is IDR 904,225 or less than USD 65, making affordability for implementing the system.

ABSTRACT

Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) a virus from the Coronaviridae family that causes the Coronavirus disease (COVID-19), has emerged and spread since December 2019. Since then, many in vitro and in vivo models for COVID-19 research has been developed. Objective(s): This study aimed to determine infectivity rate of various SARS-CoV-2 strains in the Vero E6 cell line. Material(s) and Method(s): Four SARS-CoV-2 strains (Wuhan, Alpha, Beta, and Delta) were isolated from clinical samples. Virus titre concentration of all strains were measured using Tissue Culture Infectious Dose (TCID50) assay and Plaque assay. At similar virus titre concentration, all strains were incubated in the Vero E6 cells at 37degreeC for 72 hours. At the end of incubation period, all virus cultures were terminated and analysed using TCID50 assay. Result(s) and Conclusion(s): It was found that the Wuhan strain has the highest infectivity rate (3601 PFU/mL/72hours) towards the Vero E6 cells, followed by Alpha (2946 PFU/mL/72hours), Beta (1780 PFU/mL/72hours) and Delta (571 PFU/mL/72hours). Vero E6 cell is commonly used for virus isolation and propagation, however this cell does not mimic the primary entry sites in the human respiratory track. The successful isolation and culture of SARS-CoV-2 in the Vero E6 cell is multifactorial, with high viral titre in source clinical samples and low passage number of cell culture as key factors. Vero E6 cell is susceptible towards all SARS-CoV-2 strains and can be used as in vitro COVID-19 culture model. Further studies can be conducted to determine the influence of different cell lines on the COVID-19 infectivity.

ABSTRACT

Chronic obstructive pulmonary disease (COPD) is a common lung disease that is characterized by long-term respiratory symptoms and airflow limitation. It is important to investigate whether patients with COPD are at the increased risk of infection with SARS-CoV-2 and what are the clinical outcomes of Coronavirus disease 2019 (COVID-19). Since both diseases affect the respiratory tract, the purpose of this review was to determine whether there is an interrelationship between COPD and COVID-19. Currently, it is not clear whether COPD patients are at higher risk of SARS-CoV-2 infection;however, it is confirmed that, if they are affected by COVID-19, there is a higher rate of hospitalisation and death. COPD patients should continue prescribed COPD therapy even if they have COVID-19 infection because it is not confirmed that taking these medications changes the clinical outcomes of COVID-19 infection. Protective measures are very important in times of higher prevalence of COVID-19 since they reduce the risk of infection and help COPD patients maintain their health.

ABSTRACT

Coronavirus disease-2019 (COVID-19) is associated with cytokine storm and is characterized by acute respiratory distress syndrome (ARDS) and pneumonia problems. The respiratory system is a place of inappropriate activation of the immune system in people with multiple sclerosis (MS), and this may cause damage to the lung and worsen both MS and infections.The concerns for patients with multiple sclerosis are because of an enhance risk of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The MS patients pose challenges in this pandemic situation, because of the regulatory defect of autoreactivity of the immune system and neurological and respiratory tract symptoms. In this review, we first indicate respiratory issues associated with both diseases. Then, the main mechanisms inducing lung damages and also impairing the respiratory muscles in individuals with both diseases is discussed. At the end, the leading role of physical exercise on mitigating respiratory issues inducing mechanisms is meticulously evaluated.
