RESUMO
Objective: As of December 2021, two types of vaccines are applied in our country: inactive Coronavac and BNT162b2 mRNA vaccine. In this study, it was aimed to compare the rates of Covid-19 disease infection, pneumonia development rates and hospitalization requirement of individuals vaccinated with different vaccines. Materials and methods: Individuals at least one dose vaccinated with Coronavac inactive or mRNA active were compared for the evaluation of oxygen saturation values, SARS-CoV-2 reverse transcriptase polymerase chain reaction (RT-PCR) results for the development of pneumonia, and hospitalization. Results: 71 individuals vaccinated with mRNA vaccine and 145 individuals vaccinated with inactive Coronavac vaccine, a total of 216 individuals were evaluated. There was no significant difference between the two groups in terms of the presence of fever complaints and Sars-CoV-2 Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) positivity rates. 5.6% (n=4) of the individuals vaccinated with the mRNA vaccine had pneumonic infiltration on non-contrast computed tomography (CT) images of the thorax, while 2.8% (n=2) required hospitalization. 17.9% (n=4) of the individuals vaccinated with inactive Coronavac vaccine had pneumonic infiltration on non-contrast thoracic CT images, while 11.7% (n=17) had hospitalization requirement. Conclusion: There are currently no studies in the literature comparing the effectiveness of an inactive vaccine and an mRNA vaccine. In our study, we concluded that even if people vaccinated with the mRNA vaccine were infected with Sars-CoV-2, the pneumonic involvement and hospitalization requirements for thoracic CT were lower compared to those without the vaccine and those vaccinated with the inactive Coronavac vaccine.
RESUMO
School closures due to the Covid-19 pandemic have changed education forever and we have witnessed the rise of online learning platforms. The education units of the countries made great efforts to adapt to this new order. The expanding, quick spread of the virus and careful steps have prompted the quest for reasonable choices for continuing education to guarantee students get appropriate education and are not impacted logically or mentally. Different methods were attempted to understand how students were affected by this big change. In addition to the significance of traditional surveys and consulting services, the utilization of social media analysis is used as a supportive approach. This paper analyzes the feedback of students on social media via tweets. Deep sentiment analysis is employed to identify embedded emotions such as negative, neutral, and positive. We also aimed to classify irrelevant tweets as the fourth category. Our experiments showed that the tweets are mostly biased toward negative emotions. © 2022 IEEE.
RESUMO
Objective: Coronavirus disease 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) virus, the first cases of which were reported in Wuhan, China in December 2019. The disease often presents with major respiratory symptoms. In addition, gastrointestinal (GI) symptoms are observed. They may be the first or even the only symptoms of the disease. The aim of this study is to demonstrate the presentation of GI symptoms and their relationship to other symptoms, the clinical course and prognosis of patients with COVID-19. Methods: Included in this study were patients over 18 years of age who had been hospitalised for treatment in clinics and intensive care units due to COVID-19 between March and June 2020. The symptoms reported by the patients at the time of admission and the data collected as a result of the clinical follow-up were evaluated. Results: Out of the 1,045 patients with COVID-19, 140 patients (13.4%) had GI symptoms. The complaints of these 140 patients were nausea (53.6%), vomiting (32.1%), abdominal pain (11.4%), diarrhea (45.7%), anorexia (43.6%) and loss of taste (5.6%). In 3.2% of the patients, only GI symptoms were present, without any respiratory symptoms. Conclusion: Gastrointestinal symptoms were present at the time of admission in 13.4% of the patients with COVID-19. The most common GI symptom in the patients was nausea. Length of stay in hospital and mortality rate were higher in patients with only GI symptoms. Therefore, GI symptoms should be considered in patients with suspected COVID-19.
RESUMO
Introduction: In this study, we aimed to better understand the role of chest CT as an initial workup tool among all COVID-19 patients admitted to a tertiary hospital. Materials and Methods: We retrospectively evaluated the data of patients that were suspected for COVID-19. All patients who had both noncontrast chest CT scan with RT-PCR test results included in the study. Symptomatic patients were divided into four groups according to time between the onset of symptoms and chest CT;4 days, 5-8 days, 9-13 days, and 14 days. Chest CT findings according to symptom status, duration, and RT-PCR positivity were evaluated. Results: Data for a total of 791 patients were evaluated. The mean patient age was 51.7 19.7 years. 459 (58%) patients were male, and 332 (42%) were female. 55.1% of patients had positive and 44.9% negative RT-PCR tests. Typical, indeterminate, atypical and negative chest CT findings were seen in 241 (30.5%), 131 (16.6%), 154 (19.5%), and 265 (33.5%) patients, respectively. Among 355 patients with negative RT-PCR results, 152 (42.8%) had typical or indeterminate chest CT findings. Asymptomatic patients had a 91.9% of RT-PCR positivity. Only 123 (61.5%) patients had typical or indeterminate CT findings among symptomatic and RT-PCR positive cohort. Conclusion: The greatest value of our study is in demonstrating the value of chest CT in both patients that had symptoms but had negative RT-PCR test results and insignificance of chest CT in asymptomatic but had suspected contact with COVID-19 patients.
