Knowledge, attitudes, and willingness of adolescents towards coronavirus disease 2019 vaccine in Bangkok, Thailand

Background: The outbreak of coronavirus disease 2019 (COVID-19) was declared by the World Health Organization (WHO) as a COVID-19 pandemic on March 11, 2020. Therefore, the availability of vaccines will help develop immunity and protect people from this pandemic. The present systematic study examined knowledge, attitudes, and willingness of adolescents towards COVID-19 vaccine in Bangkok, Thailand. Objectives: The objective of the study was to evaluate the knowledge, attitudes, and willingness toward COVID-19 vaccine of key stage 4A-5 students at Satit Prasarnmit International Programme in Bangkok towards COVID-19 vaccine. Materials and Methods: The study was conducted using an online questionnaire. A total of 136 students participated. Knowledge, attitudes, and willingness of adolescents toward the COVID-19 vaccine were assessed. Differences between outcomes and socio-demographic characteristics of participants were analyzed through independent t-tests and the ANOVA. The level of willingness to vaccinate against COVID-19 was analyzed by a generalized linear model. Results: Students revealed moderate knowledge about COVID-19, correctly answering 11.08 out of 15 points (SD = 1.74), a low level of attitudes toward COVID-19 vaccine 8.49 out of 15 points (SD = 2.51), and low level of willingness to vaccinate against COVID-19 vaccine 2.29 out of 5 points (SD = 1.26), in total of 35 points (28 questions). There are statistically significant positive correlations shown between attitude towards COVID-19 vaccine and the level of willingness to vaccinate against COVID-19 vaccine (I2 = 0.384, P < 0.01%). Conclusion: This study revealed students in Satit Prasarnmit International Programme had moderate knowledge towards COVID-19, negative attitudes toward COVID-19 vaccine and low willingness to vaccinate against COVID-19. Furthermore, it indicates that there is a casual relationship between attitudes toward COVID-19 vaccine and the willingness of individuals to be vaccinated against COVID-19 vaccine. Thus, attitude toward COVID-19 vaccine acts as a major predictive factor toward the willingness to vaccinate against COVID-19 vaccine. Therefore, to increase peopleA's willingness to be vaccinated against COVID-19 vaccine, it is necessary to increase peopleA's attitude toward COVID-19 vaccine.

Expressions of miR-21 TGF-beta/Smad signaling pathway in peripheral blood of bronchial asthma patients complicated with respiratory virus infection

OBJECTIVE: To investigate the expressions of peripheral blood microRNA-21(miR-21) and transforming growth factor-beta(TNF-beta)/Smad signaling transduction pathway in patients with bronchial asthma complicated with respiratory virus infection. METHODS: Totally 109 patients with asthma complicated with respiratory virus infection(study group) and 104 patients without virus infection(control group) in the Third People's Hospital of Gansu Province between Feb.2019 and Feb.2021 were selected for the cross-sectional study. The basic data of the two groups were collected, and parameters including vital signs, lung function, peripheral blood miR-21 and TGF-beta/Smad signaling pathway proteins were measured. According to the guidelines, the patients of the two groups were divided into acute exacerbation phase and stable phase. The examination results of each group were compared and the levels of peripheral blood miR-21 and TGF-beta/Smad signaling pathway proteins expression of patients with asthma complicated with respiratory virus infection were analyzed. RESULTS: In study group, the proportion of respiratory virus infection among 109 patients was 33.94% for influenza virus, 23.85% for human rhinovirus, 19.27% for respiratory syncytial virus, 10.09% for parainfluenza virus, 6.42% for adenovirus, 4.59% for human coronavirus and 1.83% for human metapneumovirus respectively. The proportion of patients with acute exacerbation phase in the study group was higher than that in the control group, and the levels of peripheral blood miR-21, TGF-beta1, Smad7, pSmad2 and pSmad3 were higher than those in control group(P<0.05). The levels of miR-21, TGF-beta1, Smad2, Smad3, Smad7, pSmad2 and pSmad3 in peripheral blood of patients with acute exacerbation phase of asthma were higher than those of patients with stable phase of asthma(P<0.05). There were no statistical differences in peripheral blood miR-21, TGF-beta1, Smad2, Smad3, Smad7, pSmad2 and pSmad3 levels in asthma patients with different virus infections. CONCLUSION: Early respiratory virus infections might lead to increased expression of peripheral blood miR-21 and increased activation of TGF-beta/Smad signaling pathway in patients with asthma, which played an important role in acute attack of asthma.

Risk factors for COVID-19 incidence and mortality in patients on maintenance hemodialysis

Patients on maintenance hemodialysis (MHD) are highly susceptible to SARS-CoV-2 and with high mortality rates due to Coronavirus disease 2019, mainly because of the older age in this group of patients, comorbidities, compromised immune status due to uremia, as well as inability to keep social isolation because of the necessity for regular physical presence in dialysis facility. Several retrospective studies of patients on MHD in Europe, America and Asia, show high susceptibility to SARS-CoV-2 in this group of patients with very high rates of critical course of the disease and high mortality rates, reaching more than 40% The aim of this retrospective observational study was to identify risk factors among patients on intermittent hemodialysis for infection with SARS-CoV-2 as well as predictors of severe COVID-19 and fatal outcome. Materials and methods. We analyzed 69 patients receiving intermittent dialysis in Aleksandrovska University Hospital - Hemodialysis Unit. 34 of them have been tested positive for SARS-CoV-2 in the period from September 2020 (when the first case of the disease was registered for our dialysis center) up to March 2022, and are compared with a control group of 35 dialysis-dependent patients without COVID-19. Data about comorbidities, main laboratory and radiologic findings, need of hospitalization and treatment in ICU, as well as data for conducted treatment, are collected from electronic medical records. To identify predictors of severe COVID and poor outcome we compared the group of survivors with the one of non-survivors. Results. There are no significant differences between patients on MHD with and without COVID-19 except higher frequency of COPD and hypoproteinemia in the positive group. Older age, female gender, history of smoking, lymphopenia with neutrophilia, treatment in ICU and need of mechanical ventilation, signs of malnutrition - hypoproteinemia and lower levels of serum creatinine, are risk factors for severe disease and fatal outcomes. Conclusions. The course of COVID infection in dialysis-dependent patients is severe and with high mortality rate, in line with other studies worldwide. Malnutrition is the main risk factor for COVID and also main predictor for poor outcomes.

Intention to vaccinate against COVID-19 of Thai people in Trang province, Thailand: a cross-sectional study

Background: Coronavirus disease 2019 (COVID-19) is an epidemic that has greatly affected the daily life of people around the world. This epidemic, in addition to affecting lives, also affects other matters such as the economy or government administration that need to find ways to reduce the epidemic rate. That is to provide adequate quality vaccines for the people of the country. Finally, the government finds measures to stop the spread of COVID-19. Objectives: This study aimed to assess an acceptance to be vaccinated against COVID-19. Materials and Methods: Intention to be vaccinated against COVID-19 was measured with a question A"When a vaccine for COVID-19 is ready for you, will you get vaccinated?A" Response options were A"yes, A" A"not sureA" and A"no.A" Participants who responded A"not sureA" or A"noA" were asked to provide a reason. Results: A total of 400 responses were received. Overall, 38.5% (n = 154) of participants intended to get vaccinated, 29.5% (n = 117) were unsure, and 32.25% (n = 129) were not planning to get vaccinated. Factors that are independently related to vaccine hesitancy (A"not sureA" or A"yesA" response) include being male, risk perception of getting COVID-19, confidence in the government in handling the pandemic. Conclusion: A total of 400 participants, in the study, 38.5% (n = 154) of participants intended to get vaccinated, 29.5% (n = 117) were unsure, and 32.25% (n = 129) were not planning to get vaccinated. Male participants had a higher chance to refuse to vaccinate more than female 2.69 times. Predictive factors for COVID-19 vaccination were risk perception of contracting COVID-19 and lack of confidence in the government handling the pandemic of COVID-19.

ASSOCIATION OF URIC ACID LEVELS WITH COVID-19 SEVERITY DURING 2020 AND 2021 YEARS

BackgroundThe decrease in uric acid levels attracts more and more attention from clinicians every year [1]. In particular, a factor such as Covid-19 can cause a significant decrease in uric acid due to its increased excretion by the kidneys [2]. This retrospective study aimed to determine changes in the level of uric acid in different years, which allows us to assume the influence of different strains of Covid-19 on uric acid.ObjectivesTo analyze the relationship between uric acid levels through admission to the hospital and Covid-19 severity during 2020 and 2021 years.MethodsOur retrospective study includes 127 hospitalized patients with confirmed Covid-19 in 2021 and 63 patients in 2020 (only patients who didn't receive urate-lowering therapy). Most patients were over 45 years old (84,2% vs 90,5%), women and men almost equally. The severity of Covid-19 we determined by the type and presence of oxygen support ((1) without O2, (2) O2 by mask or nasal cannula, (3) continuous positive airway pressure, (4) positive bi-pressure in the airways or high-flow oxygen, (5) invasive ventilation). A chi-squared test and comparison of means were used.ResultsWe cannot establish the dependence of the uric acid level on the severity of the course of the Covid-19 disease, which is determined by the type of oxygen support in both 2020 and 2021. For example, in 2021, the difference between the least severe type (without O2) and the most severe (invasive ventilation) was almost the same (246.2 vs 277.12 µmol/L), as between O2 by mask or nasal cannula and positive bi-pressure in the airways or high-flow oxygen (257 vs 239.1 µmol/L). However, it was established that in 2020, higher indicators of the level of uric acid were observed for all types of oxygen support. For example, for patients who were without O2, it is higher by 72.95 µmol/L, which is statistically significant. In addition, we analyzed the dependence of the uric acid level on such indicators as the patient's age, the level of lymphocytes, C-reactive protein, and LDH at admission to the hospital. As a result of the analysis, it was found that the dependence is present for the LDH indicator (the lower the LDH, the higher the uric acid: chi-square at the level of 0.05), and for all other indicators, it was absent in 2021. In 2020, a positive relationship between CRP, LDH, and uric acid levels was also observed.ConclusionAlthough there is a trend towards lower uric acid levels in the background of Covid-19, it is not a marker of a severe disease course. The lower uric acid levels in 2021 are likely due to a feature of the strains circulating in 2021 that caused more significant renal excretion of uric acid.References[1]Hu F, Guo Y, Lin J, Zeng Y, Wang J, Li M, Cong L.

Characteristics of COVID-19 patients and risk factors of mortality in the early times of pandemic, Herat-Afghanistan

Objective: Coronaviruses are a large family of viruses that cause different types of diseases. This study aims to evaluate the risk factors for mortality based on comorbidity and sociodemographic characteristics among COVID-19 patients. Methods: This cross-sectional study conducted in Herat, Afghanistan, from February 24 to July 5, 2020, used data provided by the public health department, including sociodemographics, symptoms, comorbidities, hospitalization, contact history, and COVID-19 test type. The Chi-square test was used to observe differences between categorical variables. In bivariate analysis, all independent variables with a significant p-value were put into the model. Odds ratios and 95% confidence intervals were calculated, and a p-value less than 0.05 was considered statistically significant. Results: The study analyzed 11,183 COVID-19 cases, with a 53.5% positivity rate. Recovery rates in the city and Herat province districts were 96.2% and 94.7%, respectively. Case-fatality rates varied with age, with 0.4% for those aged 1-29 and 33% for those aged 80-105. Mortality rates were highest for those with COPD and cancer, at 12.5% and 18.2%, respectively. In the logistic regression results, age, gender, and COPD were significant variables for COVID-19 mortality. Conclusion: By providing more health service facilities to people in risk groups, especially in rural areas, the mortality rate of COVID-19 and other diseases can be decreased.

Determinant factors of the improvement of nutritional status (based on height-for-age index category) in children during the COVID-19 pandemic: a cohort study of children's growth and development in Bogor

The COVID-19 pandemic is predicted to trigger a global economic and food supply crisis, which further affects children's nutritional status as a vulnerable group. This study aimed to observe alterations in nutritional status before and during the COVID-19 pandemic (during 2019-2021) and determinant factors involved in the improvement of nutritional status (based on the height-for-age Z-score (HAZ) index category) during the COVID-19 pandemic. The findings were intended as evidence-based suggestions for policy formulation concerning the improvement of child nutritional status and stunting reductions. This study was part of a cohort study of children's growth and development conducted by National Institute of Health Research and Development (NIHRD) in Bogor city-Indonesia. The analysis was conducted on 565 children under five in 2019 with height measurement data in 2019 and 2021, environmental conditions, parental education, consumption habits, and social assistance. Children were classified as having an improved nutritional status if the HAZ category increased in 2021 compared to 2019. In addition, multiple logistic regression analyses were performed to predict determinant factors involved in improving the child's nutritional status. In this study, 17.5% of children had improved nutritional status, and 79.3% had a steady nutritional status. However, there were 3.2% of children with decreased nutritional status. Model factors determinant related to improved nutritional status includes consumption more than once per week of red meat (adjusted odds ratio (aOR) = 2.15;95% confidence interval (CI): 1.06-4.35, p=0.034), milk consumption more than once per week (aOR = 1.56;95% CI: 0.89-2.74, p=0.119), and age under 5 years old (aOR = 1.86;95% CI: 1.14-3.15, p=0.016). Children under five years old, the consumption of red meat and milk more than once a week have the opportunity to improve nutritional status (by height-for-age index) in children.

Gastrointestinal features of the multisystem inflammatory syndrome in children (MIS-C) following COVID-19 infection in selected referral hospitals in Iran

Background and purpose: Multisystem Inflammatory Syndrome in Children (MIS-C) occurs after having COVID-19. The severity and outcomes of COVID-19 with gastrointestinal symptoms are higher. The aim of this study was to investigate gastrointestinal manifestations in MIS-C patients in selected referral hospitals in Iran to obtain comprehensive information about the treatment and prevention of MIS-C. Materials and methods: In this cross-sectional study, all MIS-C patients <21 years in Dec 2019 to Oct 2021 were included. The patients were identified by the Centers for Disease Control and Prevention (CDC) checklist and data were analyzed applying t-test and Chi-square in STATA11. Results: There were 225 patients with a median age of 55 months (26-96 months), including 59.56% boys and all had fever on admission. At least one gastrointestinal symptom was seen in 200 patients and the most common symptoms were vomiting (60.9%) and abdominal pain (45.77%). Almost 60% of the patients had positive RT-PCR results. Among the patients with and without gastrointestinal symptoms 85.5% and 48% were admitted to intensive care unit (ICU), respectively. There were significant differences between the two groups in respiratory symptoms, ALT, AST, NT-pro BNP, ESR, and PLT (P < 0.05). All patients without gastrointestinal symptoms were discharged but nine patients in the group with gastrointestinal symptoms deceased. Conclusion: According to the current study, gastrointestinal symptoms are common in MIS-C patients and are associated with higher rates of death and intensive care unit admission. Therefore, in providing services to COVID-19 patients, all typical and atypical signs and symptoms should be considered to prevent unnecessary interventions.

The impact of the COVID-19 pandemic on medical education: adaptability and remote learning experience of the Peruvian American Medical Society

The COVID-19 pandemic had a significant impact on medical care and medical education in Peru. In response, the Peruvian American Medical Society (PAMS), a charitable medical organization based in the USA, pursued its medical and educational missions in Peru by adopting virtual learning technology. We developed closer collaborative relationships with several medical schools and the Peruvian Association of Medical Schools (ASPEFAM) while offering a faculty panel of twenty-four members to provide lectures and multidisciplinary webinars in Spanish. We conducted 19 webinars including COVID -19 and non-COVID-19 related topics that over the last two years attracted 14,489 participants from 23 countries. They were the foundation for twenty publications in Peruvian medical journals. Our clinical investigations competition was positively received as was our pilot project on research mentorship. The COVID -19 pandemic had a positive effect on the educational mission of PAMS in Peru.

VALIDITY AND RELIABILITY OF MEASUREMENT OF PERIPHERAL OXYGEN SATURATION DURING THE 6-MINUTE WALK TEST IN PATIENTS WITH SYSTEMIC SCLEROSIS

BackgroundThe 6-Minute Walk Test (6MWT) is a standardised method routinely used to screen for and monitor interstitiel lunge disease and/or pulmonary arterial hypertension in patients with systemic sclerosis (SSc). Studies shows that esaturations during the 6MWT are associated with severity of pulmonary manifestations in patients with SSc [1]. Digital sensors are commonly used to measure peripheral oxygen saturation (SpO2) during the 6MWT. However, digital-based sensors may have important limitations in patients with SSc due to disease-related microangiopathy, Raynaud's phenomenon, sclerodactyly and motion artifacts during the 6MWT [2]. Sensors located at more central body positions may therefore be more accurate as these as less prone to Raynaud attacks.ObjectivesTo determine the validity and re-test reliability of peripheral oxygen saturation measured at the finger, forehead, and ear during the 6MWT in patients with SSc.Methods82 patients with SSc had an arterial line placed while performing the 6MWT. Peripheral oxygen saturation was simultaneously measured by finger, forehead, and earlobe sensors and compared to the arterial oxygen saturation (SaO2) measured before and after the 6MWT. 40 patients repeated the 6MWT one week later. We used Bland-Altman plots to display the agreement between SpO2 and SaO2, and between the minimal SpO2 (minSpO2) one week apart. The intraclass correlation coefficient (ICC, 95% confidence interval 95% CI]) for repeated measurement of minSpO2 was calculated.ResultsThe mean difference (SpO2 - SaO2, ± standard deviation [SD]) after the 6MWT was –3.3% (±4.82), 0.15% (±1.55), and 1.36% (±1.93) for the finger, forehead, and earlobe, respectively (Table 1).The finger minSpO2 also demonstrated the poorest re-test reliability: The mean difference in minSpO2 (visit2-visit1, ±SD) was 1.28% (±5.3), 0.74% (±4.36) and –1.10% (±2.87),). The ICC (95% CI) showed good agreement using the ear and forehead probe (ICCear = 0.89 [0.80;0.94];ICCforehead = 0.88 [0.60;0.87]), while a modest reliability was found using the finger probe (ICCfinger = 0.65 [0.43;0.80]).ConclusionPeripheral oxygen saturation should be measured using either the earlobe or forehead during the 6MWT in patients with SSc.References[1]Villalba, W.

Relationship between social support and psychological resilience and post-traumatic stress disorder in college students

Objective To investigate the characteristics of post-traumatic stress disorder (PTSD) in college students during the outbreak of COVID-19, and to explore the mediating role of psychological resilience between social support and PTSD. Methods By using direct selection method, 572 college students in Anhui and Shanghai were selected and administered with General Characteristics Questionnaire, the PTSD Checklist-Civilian Version(PCL-C), Psychological Resilience Scale(PRS) and Social Support Rating Scale(SSRS). Results Among the participants, 25.0% had moderate PTSD symptoms, 11.7% had obvious PTSD symptoms, and the positive rate of PTSD was 36.7%. The prevalence of PTSD in college students was higher in males than in females (X2=4.31, P < 0.05). The junior students were higher than other students (X2=16.81, P < 0.01). The scores of social support, psychological resilience and PTSD were (33.79+or-4.83), (92.17+or-13.39) and (35.50+or-11.39), respectively. The correlations of all variables were statistically significant(r=-0.49-0.76, P < 0.05);The mediation test showed that social support could not only negatively predict PTSD directly(direct effect was -0.35), but also indirectly affect PTSD through psychological resilience(indirect effect was -0.32). Conclusion More than one third of college students have PTSD symptoms, and psychological resilience plays a partial mediating role in the relationship between social support and PTSD, social support can both directly and negatively predict PTSD and indirectly affect PTSD by increasing an individual's psychological resilience.

The Spectrum of Pulmonary Histomorphology Changes in COVID-19 Cases

Introduction/Objective Pulmonary specimens following COVID-19 virus infection demonstrate a spectrum of pulmonary histomorphology. Six patients with a history of COVID-19 infection are summarized in this review. The purpose of our study is to elucidate any possible correlations between clinical, laboratory, radiographic, and pathologic findings in COVID-19 patients. Further, we aim to characterize both non-specific and specific histomorphology and cytomorphology in COVID-19 patients. Methods/Case Report Six patients with known COVID-19 infection and lung biopsies/resections are identified. A chart review is performed to collect clinical histories, the results of COVID-19 PCR testing, radiographic impressions, pathologic interpretations of histology, and clinical outcomes. Information is summarized and tabulated. Results (if a Case Study enter NA) The most common, non-specific histological findings are focal/diffuse acute lung injury, organizing lung injury, or a combination of both patterns. Unique features of COVID-19 infection are identified in three cases, which illustrate viral cytopathic changes within hyperplastic pneumocytes. These include basophilic, vacuolated, granular cytoplasm and variably sized cytoplasmic/nuclear inclusions. Virus-loaded pneumocytes are typically identified in the organizing phase, and rarely in the acute lung injury phase. Immunohistochemical staining of anti-nuclear capsule antibody with appropriate controls shows focal positive staining in one case. SARS-CoV-2 PCR is positive in formalin-fixed paraffin-embedded (FFPE) tissue, while a serum PCR assay is negative. Conclusion The severity of clinical symptoms and clinical outcome are unrelated to the degree of lung involvement. Viral cytopathic changes are identified in three cases, with these specific findings associated with the organizing phase of lung injury, and either concurrent PCR positivity or positive immunohistochemical staining.

Influence of massage on respiratory and circulatory parameters in a post- COVID-19 patient: a case study

Monitoring the SaO2 levels and other respiratory function parameters after recovering from COVID-19 can have essential meaning in the assessment of the efficacy of using physiotherapy methods, including classical massage. Purpose of the research was to assess the influence of an individual classical back massage session as well as the effects of an entire 8-session back massage therapy on SaO2, HR and spirometry parameters in a patient after recovering from COVID-19, with constant monitoring of massage areas' temperature changes. Data and methods. The study comprised a case study of a patient who recovered from COVID-19. The patient was subjected to a classical back and spine massage therapy utilising all the basic techniques. The design was based on the results of the following tests: lung x-ray, SaO2, HR, spirometry parameters, and the 6-minute walking distance test. The degree of the influence of the classical massage techniques was monitored using the infrared thermography. Results. Continuous oxygen saturation monitoring during the massage sessions enabled to observe a decrease in the level of this parameter during utilisation of rubbing and tapotement on muscles of both the right and the left side of the back. During the usage of the intense massage techniques SaO2 dropped maximally to 92-93%. Such decrease was noted after massaging the right as well as the left side of the back, during every massage session. I addition it was found that in the case of the patient who recovered from COVID-19 changing the body position from sitting down to lying down after the massage session the level of tissues saturation decreased. The observed changes in the VA/Q ratio that occurred in response to the 8-session massage therapy lasting for 3 weeks might indicate that better conditions for ventilation and oxygen perfusion at the alveolar surface were reached. This translated in the patient who recovered from COVID-19 into 2% increase in oxygen saturation level after completing the massage therapy. Conclusion. Utilising the intense rubbing and tapotement techniques has to be carefully considered due to their significant influence on decrease in the level of saturation.

Life expectancy and COVID-19 infection: a population-based cross-sectional study

Background and Objective: Life expectancy and the consequences of its impairment may affect quality of life and suicide. The aim of this study was to assess the impact of COVID-19 on life expectancy in residents of Gonabad city. Methods: This cross-sectional study was conducted on 300 Gonabad residents (general population) from February 2021 to April 2022 using stratified-random sampling method. Data collection was performed through phone interview. Demographic questionnaire and Schneider's life expectancy scale were used. Data analysis was performed using the SPSS software version 23. Findings: Of the 300 participants (53% female and 47% male), 153 were COVID-19 recovered and 147 did not have the history of COVID-19. The average life expectancy score in COVID-19 recovered participants was significantly lower compared to those without the history of COVID-19 (29.17 +or- 5.96 and 31.94+or-4.34, respectively, p=0.001). Also, there was a significant and positive relationship between mean scores of life expectancy and age, gender, education, economic status, the presence of high-risk individuals at home, history of underlying diseases, and smoking (p<0.05). Conclusion: The results of this study stated that life expectancy score in COVID-19 recovered participants was a lower than that of participants without COVID-19 history. Therefore, the role of other variables, including age, gender, and disease history on life expectancy was more prominent on life expectancy in COVID-19 recovered participants.

Knowledge, understanding, attitude, and preventive behavior toward COVID-19: a study among high school students in Loei Pittayakom, Thailand

Background: COVID-19 pandemic has affected humanity in several aspects of life. Not only create health problems, but also economic and social problems. To cope with this pandemic, we need to know and understand how to have the COVID-19 preventive behavior. Hence, this study will be focusing on factors that influence people to have COVID-19 preventive behavior. Objectives: The aim of this study is to assess knowledge, attitude, and COVID-19 preventive behavior of high school students. Materials and Methods: The study was conducted using a questionnaire. A total of 325 students participated. Knowledge, attitude without presence of rules, and attitude with presence of rules toward COVID-19 preventive behavior were assessed. Independent t-test and analysis of variance were used to analyze differences between outcomes and socio-demographic. COVID-19 preventive behavior was analyzed by a generalized linear model. Results: Students revealed a good level of COVID-19 related knowledge, correctly answering 4.48 (standard deviation [SD] = 0.70) questions in a total of 5, good levels of attitude both without and with the presence of rules, average score was 11.05 (SD = 1.16) of four questions and 15.86 (SD = 2.07) of six questions, respectively, and a good level of COVID-19 preventive behavior, the average scores at 44.28 (SD = 6.68), in a total of 11 questions. Conclusion: This study revealed a good level of knowledge, attitude both without and with the presence of rules and COVID-19 preventive behavior among high school students at Loei Pittayakom School, Thailand. Mainly, the factor that may influence them to get a high score in all four sections is staying active with news and the latest information presented on the internet. In addition, the study demonstrated that there was a relationship between attitude with the presence of rules and COVID-19 preventive behavior. Therefore, having regulations can lead to having preventive behavior.

Analysis of using telemedicine application for pregnant women during COVID-19 pandemic based on ISO 9241-11

Background: The COVID-19 pandemic has affected the performance of several sectors, one of which is the quality of maternal and child health services. One of the factors contributing to the decline in the quality of maternal and child health services is limited access during the COVID-19 pandemic. Telemedicine is here as one of the answers to overcome the problem of limited access to health services during the COVID-19 pandemic. This study aims to analyze the use of telemedicine applications by pregnant women during the COVID-19 pandemic using the ISO 9241-11 framework. Subjects and Method: This research method is an observational study with a descriptive approach to analyze usability in three measurement aspects namely effectiveness, efficiency, and satisfaction. The number of samples used was 42 pregnant women who had used telemedicine applications that had been determined during the COVID-19 period with a sampling technique using random sampling. The instrument used is an adaptation of the Standardized Usability Questionnaire (SUQ) which will be analyzed using the Structural Equation Modeling-Partial Least Square (SEM-PLS) technique to determine the usability score of the application. Results: Based on the results of the Structural Equation Model-Partial Least Square (SEM-PLS) analysis, the ISO 9241-11 model has a goodness-of-fit model with an R-square value of 0.760 and a Q-square value of 0.577 with a Goodness of Fit (GoF) of 0.780. The effectiveness variable has a significant effect on the usability variable of the Teman Bumil application at a significance level of 5% with a statistical T value of 1,955. There is not enough evidence for the efficiency and satisfaction variables to say they have a significant effect on the usability of the Teman Bumil application at a 5% significance level with T-statistic values of 0.866 and 1.452. The usability score for the Friends Pregnant application is 44.45. Conclusion: The usability score obtained by the Teman Bumil application is 44.45, which means that Sahabat Bumil application has not been accepted by users as a system product that can help effectively, efficiently and satisfactorily.

Comparing the effects of endurance and resistance training programs on some pulmonary, functional, and quality of life indicators in patients with COVID-19 discharged from hospital

Background and purpose: The present study investigated the effect of six weeks of endurance and resistance training on pulmonary indices, physical performance, and quality of life in COVID-19 patients after discharge from hospital. Materials and methods: Thirty six patients with COVID-19 (mean age: 38.76+or-0.98 years, mean weight: 81.86+or-2.88 kg) were selected. At the beginning and end of the study, pulmonary (FEV1, FVC, FEV1/FVC, and MVV), physical (6-minute walk test), quality of life (SF-36), and anthropometry tests were performed. The patients were divided into three groups: Endurance training (45 minutes at 60-75% estimated HR), Resistance training (45 minutes at 40-70% of I-RM), and controls. The intervention was conducted for 6 weeks (3 sessions). One-way ANOVA test was used for statistical analysis. Results: Findings indicated a significant increase in FEV1 (P=0.029), FVC (P=0.047), FEV1/FVC (P=0.043) in the endurance training group compared to the control group, while difference was observed in MVV (P=0.041) and FEV1/FVC (P=0.022) between endurance training and resistance training groups. The 6-minute test distance increased in the endurance training (P=0.0001) and resistance training (P=0.001) groups compared to the control group, but no difference was observed between the training groups (P=0.48). Endurance and resistance training programs induced significant improvements in physical performance (P=0.024 and P=0.09, respectively) and general health (P=0.022 and P=0.015, respectively) dimensions compared to the control group. Conclusion: Moderate-intensity endurance training can improve pulmonary function, physical performance, and quality of life in patients with COVID-19 after discharge from hospital and can be used in rehabilitation programs of these patients.

Oesophageal and oral ulcer tuberculous associated with human T-cell lymphotropic virus type 1 (HTLV-1) and SARS-CoV-2 infection

Oesophageal involvement due to tuberculosis (TB) and coinfection with HTLV-1 is rare and can be complicated by the presence of other infections that affect the mucosa of the upper respiratory tract, such as COVID-19. We present the case of a 27-year-old male patient, with 3 months of illness, weight loss, dysphagia, and ulcers in the oral cavity. Tomography showed oesophageal perforation and after oesophageal ulcer biopsy, TB was diagnosed, in addition to infection by HTLV-1 and severe acute respiratory syndrome coronavirus 2 (SARS-COV-2). The patient responded satisfactorily to antituberculous treatment and corticosteroids. Considering the association between rare extrapulmonary tuberculosis and other immunosuppressive pathologies, it is crucial to identify these pathologies in such patients.

Assessing the clinical manifestations, laboratory and radiological findings of hospitalization of pediatrics patients with COVID-19 in pediatric hospital of Amirkola, Babol

Variant Omicron was discovered as a newest severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The first emergence of the omicron variant was detected in November 2021. In this study, we investigated the clinical manifestation, laboratory and radiological findings and responding to treatment of 70 pediatric patients with positive RT- PCR COVID-19 in Omicron peak. We described 20 criteria associated with efficacy, such as demographic data, clinical manifestation, laboratory and radiological findings. All of the patients received Remdesivir that 5.7% of patients responded to the treatment. No patients were given Intravenous Immunoglobulin (IVIG). This is the first study aimed at assessing symptoms clinical manifestation among hospitalization pediatrics patients in pediatric Hospital of Amir kola, Babol. The findings of this study can be effective in preventing and controlling disease transmission among children.

Respiratory manifestations of post-COVID syndrome

Overcoming infection with coronavirus disease 2019 (COVID-19) can lead to the persistence of various symptoms in some patients. The complex of symptoms causally related to severe acute respiratory coronavirus 2 infection is called post-COVID syndrome. One of the most common respiratory complications is pulmonary fibrosis, especially after critical course of the disease. In some patients, ho-wever, only the peripheral airways are affected by the air-trapping seen on high-resolution computed tomography scans. Less common respiratory complications include sarcoidosis and pneumatoceles. This narrative review summarizes current knowledge about pulmonary involvement as part of post-COVID syndrome.
