ABSTRACT
Purpose: This study aims to identify the dietary patterns of two groups of subjects (with and without COVID-19), and to assess the relationship of findings with the prognosis of COVID-19 and metabolic risk parameters. Design/methodology/approach: This study included 100 individuals in the age range of 19-65 years. The medical history, and data on biochemical, hematological and inflammatory indicators were retrieved from the files. A questionnaire for the 24-h food record and the food intake frequency was administered in face-to-face interviews, and dietary patterns of subjects were assessed. Findings: In individuals with COVID-19, the hip circumference, the waist-hip ratio and the body fat percentage were significantly higher (p < 0.05), and the muscle mass percentage was significantly lower (p < 0.05). Mediterranean diet adherence screener (MEDAS), dietary approaches to stop hypertension (DASH) and healthy eating index-2015 (HEI-2015) scores were low in the two groups. A linear correlation of DASH scores was found with the muscle mass percentage (p = 0.046) and a significant inverse correlation of with the body fat percentage (p = 0.006). HEI-2015 scores were significantly and negatively correlated with body weight, body mass index, waist circumference, hip circumference and neck circumference (p < 0.05). Every one-unit increase in MEDAS, DASH and HEI-2015 scores caused reductions in C-reactive protein levels at different magnitudes. Troponin-I was significantly and negatively correlated with fruit intake (p = 0.044), a component of a Mediterranean diet and with HEI-2015 total scores (p = 0.032). Research limitations/implications: The limitation of this study includes the small sample size and the lack of dietary interventions. Another limitation is the use of the food recall method for the assessment of dietary patterns. This way assessments were performed based on participants' memory and statements. Practical implications: Following a healthy diet pattern can help reduce the metabolic risks of COVID-19 disease. Originality/value: Despite these limitations, this study is valuable because, to the best of the authors' knowledge, it is the first study demonstrating the association of dietary patterns with disease prognosis and metabolic risks concerning COVID-19. This study suggests that dietary patterns during the COVID-19 process may be associated with several metabolic risks and inflammatory biomarkers.
ABSTRACT
Background : Thromboelastography (TEG) may estimate the dynamics of blood coagulation from the activation of clotting factors to fibrin formation, clot stabilization, and clot lysis. Therefore, TEG may be helpful to predict thromboembolic events and estimate clinical outcome in patients with COVID-19. Aims : In this study, we wanted to evaluate the coagulation abnormalities including TEG analyses in children that are hospitalized for COVID-19 and aimed to assess the utility of TEG in clinical practice in terms of course of the disease, treatment response, and outcome. Methods : A total of 66 patients who were ≤18 years old and hospitalized in infection ward for COVID-19 were evaluated prospectively. Clinical and laboratory findings at admission, course of the disease, treatment modalities, development of MIS-C, and outcome of patients were noted. Haemoscope TEG analyzer (Haemoscope, USA) was used. Results : Five patients (7.6%) had thrombocytopenia. PT was prolonged in 5 patients (7.6%) and APTT in 3 patients (4.5%). Eight patients (12.1%) had elevated levels of D-dimer. A total of 16 patients (24.2%) had at least one abnormality at in TEG analysis. Eleven patients (16.6%) had an abnormality related to hypercoagulation such as decreased R/K, increased MA/Angle or increased CI. MIS-C developed in 3 patients (4.5%) during clinical follow-up;all of them had a normal graphic for TEG, even though they had increased D-dimer levels (>3000 ng/mL) at admission. There was no difference in TEG abnormalities between treated and untreated patients ( P = 0.76). Thromboembolic complications or bleeding events were not observed. None of the patients needed mechanical ventilation. None of them died. Conclusions : Abnormal TEG features may be the most common finding regarding coagulopathy at admission in these patients, followed by elevated D-dimer levels. Abnormal TEG results at admission is not able to predict the course of the disease, treatment results, and outcome in pediatric patients who did not need mechanical ventilation.
ABSTRACT
Objective: SARS-CoV-2, emerged in December 2019 in the city of Wuhan in the People's Republic of China affects children as well as all age groups. The aim of the study was to evaluate the clinical features and outcomes of pediatric cases with COVID-19 in the first month of the epidemic in Turkey. Method: This single center cross-sectional study was conducted in University of Health Sciences Dr Behcet Uz Child Diseases and Pediatric Surgery Training and Research Hospital during the period of March 11 - April 20, 2020. Demographic, epidemiological and clinical data were collected from medical records. All patients were confirmed by real time reverse transcription- polymerase chain reaction. Chidren were classified as asymptomatic, mild, moderate, severe, and critically ill patients. Results: In this study, we reported the clinical characteristics of a case series involving 30 chilren with COVID-19 aged from 23 days to 16 years. Twenty-nine (96.7%) patients had confirmed contact with family members for COVID-19. The majority of patients were asymptomatic (50%) or had mild symptoms (26.7%). Fever (46.6%) and cough (33.3%) were the most common symptoms. Conclusion: Our study indicated that COVID 19 in children exhibited less severe symptoms and had better outcomes
ABSTRACT
The COVID-19 pandemic caused significant disruptions to ordinary lives. These disruptions included restricting human movement through local ‘`lockdowns’'. This paper applies a multi-temporal analysis of Differential Interferometric Synthetic Aperture Radar (DInSAR) to evaluate the relationship between restrictions on movement and solid waste production in landfill sites. We selected three landfill sites from Africa, Euro-Asia, and America to assess the impact of restricted mobility on waste production. Our research shows that solid waste production and restrictions on human mobility are significantly correlated. Our study indicates that a reduction in human mobility increases human waste production even after accounting for changes in economic activities. The research highlights the benefit of using remote sensing SAR data for monitoring the impact of human activities on the environment. The use of remote sensing data is crucial for these applications, given that the outcomes might be counter-intuitive.

ABSTRACT
The research aims to examine the perceptions and attitudes of students studying in the department of sports management towards the Covid-19 epidemic. Covid-19 has had a huge impact on the world and has affected many segments of society. The research was conducted using a descriptive survey model, one of the quantitative research methods. The data obtained in the study went through statistical processes. In the research, the scores and differences between the students were examined by considering the variables of gender, class, and age. The statistical processing process of the data obtained from the research was carried out in the SPSS 22.0 program.
