Prioritising climate change actions post COVID-19 amongst university students, a Q methodology perspective in the United Arab Emirates

The COVID-19 pandemic caused strict regulations to lower transmission rates. Industries were shut down, people were in lockdown, and travel was curtailed. Restrictions were in effect for an enough period for people's behaviour to change. For example, online meetings rather than needing to travel. This opens the possibility for alterations to the perception that it is possible to commit to effective climate change actions. A Q methodology study was conducted to analyse how 33 university environmental students across the United Arab Emirates perceive the importance of prioritising climate change actions post-pandemic. Statistical analysis yielded four discourses. The first emphasises the need to learn lessons about climate sustainability and sustain them post-pandemic. The second, more pessimistic but advocates preventing a return to pre-pandemic norms by implementing post-pandemic climate change regulations. The third expects economic recovery to take priority over reducing emissions. The fourth raises opportunities and challenges for environmental sustainability post-COVID-19.

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.

Attitude and acceptance toward COVID-19 vaccines among Kabul city's residents: a cross sectional study

Objective: The present study aimed to assess the attitude and perception of Kabul city's residents toward COVID-19 vaccines hesitancy and acceptance. Methods: Applying a cross-sectional study design, the data was collected from 665 participants in Kabul city using a predesigned validated questionnaire. For statistical analysis, Spearman correlation, chi-square, and logistic regression techniques were used. Results: Although the vaccine availability was limited for the public during the survey period, 70.5% of the participants were willing to receive COVID-19 vaccines. Meanwhile, 49.2% participants were concerned about the COVID-19 vaccines side effects. The presence of positive COVID-19 cases among family members and friends (OR: 2.7), presence of fears during COVID-19 pandemic (OR: 4.4) and beliefs that vaccine has important and vital role in people's protection against COVID-19 (OR: 5.3), increase the likelihood of vaccine acceptance among the participants. On the other hand, participant's mistrust of the safety of COVID-19 vaccines (OR: 0.21) and disbelief on ministry of public health "MoPH" advice about COVID-19 vaccine safety and efficiency (OR: 0.27) decrease the odds of COVID-19 vaccine acceptance among the respondents. In addition, a strong correlation was found between vaccine attitude and vaccine acceptance scales (Spearman p=0.52, p<0.001). Conclusion: Although majority of the participants were willing to receive the COVID-19 vaccines, due to high level of participant's concerns about COVID-19 vaccines-related side effects, a great proportion of the respondents were hesitate to receive the COVID-19 vaccines. Accordingly, public awareness about COVID-19 vaccines must be increased to counteract incorrect and misleading propaganda about vaccination and immunization.

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.

Stress and coping among elderly during the COVID-19 pandemic in Sulaimanya city in Kurdistan region of Iraq

This study aimed to find out the level of stress and coping methods among elderly in Sulaimanya city during the pandemic COVID-19. Through the snowballing sampling method, 394 elders were included to this study. After validation, two scales were used in this study;stress subscale from Depression, Anxiety and Stress Scale (DASS-21) and a culture-bound scale for determining coping methods. The results of this study showed that participants experienced a mild level of stress. Male participants, elders who live with their family, unvaccinated elders, physically passive elders have had higher stress level than female, elderly home, vaccinated, physical active elders. The findings also indicated that spiritual connection was the most common coping method used by the sample. Results of this study are the first and foremost way to share elder's unexpressed messages;it also can be a way for verbalizing their unspoken feelings. These results may also inform the elder's caregivers that elder's stress level and illness anxiety was not very high, strengthening their social support and spiritual connection may help them to reduce their distress into a lesser degree.

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.

Assessment of adjustment disorder in people with COVID-19 infection

Objective: This study aimed to evaluate the development of adjustment disorder according to the ADNM-20 (Adjustment Disorder New Module-20) scale in participants who were followed up for Covid-19 infection. Methods: A cross-sectional survey was conducted from September to November 2020. After sample size calculation, we aimed to reach minimum 170 people out of 1290 people who applied to the hospital for Covid-19 disease treatment. Participants were selected from the patients admitted to the hospital using a simple stratified random sampling method. We reached 182 people after treating the patients who were followed up with Covid-19 infection in a University Hospital in Istanbul, Turkey. A questionnaire and the Adjustment Disorder New Module-20 scale were applied via phone / mail at the end of the 6th month after Covid-19 related hospital admission by researchers. Results: Adjustment disorder was found in 28.8% (n=42) of the participants disorder according to the ADNM-20 scale. While the rate of development of adjustment disorder due to Covid-19-related stress was 26.7% (n=39);the rate of development of adjustment disorder due to non-Covid-19 stress was found to be 2.1% (n=3). With the increase in stress load, the development of adjustment disorder increased significantly. The frequency of developing Covid-19-related stress-related adjustment disorder was statistically significantly increased with the duration of exposure to stress. Conclusion: We have found out that one out of every four people who apply to the hospital for healthcare services due to Covid-19 infection may develop an adjustment disorder. Assessment of the adjustment disorder more frequently and making early interventions may contribute to the prevention of progressive mental disorders.

Assessment of positive airway pressure treatment adherence and sleep quality in sleep apnea patients during COVID-19 pandemic: multi-center cross-sectional study results

Background: Patients with obstructive sleep apnea (OSA), related to their disease consequences and treatment modalities, are physically and mentally vulnerable during the outbreak. Objectives: To investigate the association between pandemic-related changes and positive airway pressure (PAP) adherence and sleep quality in OSA patients. Methods: This was a multi-center cross-sectional study, and the necessary data were collected prospectively. A total of 221 patients were included in the study, who were invited from four different centers from June 1 - December 1, 2020. Pittsburgh Sleep Quality Index (PSQI) was administered to evaluate sleep quality. Information on demographics positive airway pressure (PAP) device use, Coronavirus disease (COVID-19) a questionnaire collected related changes. Patients >18 years with a diagnosis of OSA and prescribed PAP treatment before the pandemic period were included in the study. Lack of cooperation with the questionnaires and incompliant with PAP treatment for longer than one year were the exclusion criteria. Results: Of the 221 participants, 79.2% were men. The mean apnea-hypopnea index was obtained at 40.8+or-24.3. A positive COVID-19 test was reported in nine cases, and three patients had hospitalization. During the pandemic, 102 (46.2%) subjects were retired, 26 (11.8%) lost their jobs, and 34 (15.3%) reported home office work or on-call or on leave. Poor sleep quality was found in 54 (24.4%) individuals. It was also reported that poor sleep quality was more common in those who reported mask use difficulty (38.7% vs. 18.9%;P=0.004) and increased or decreased PAP use (increased, decreased, no change in PAP use: 45.5%, 36.0%, 19.4%, respectively;P=0.01). The good sleep quality group had higher PAP use than the poor sleep quality group (6.2+or-1.5 vs. 5.3+or-2.4 night/week;P=0.002;6.2+or-1.5 vs. 5.5+or-2.2 hour/night;P=0.01). Conclusions: Pandemic period had several negative effects on sleep apnea patients regarding sleep quality and social lives which also influenced PAP adherence in OSA patients. Most patients did not change their regular PAP use attitudes during this period. Similar to the pre-COVID-19 disease period, PAP adherence and compliance positively influenced sleep quality;people who were "good sleepers" were the ones who were the "good PAP device users".

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.

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.

Whole-inactivated SARS-CoV-2 vaccines: from fear to hope

Undoubtedly, vaccination can be one of the promising approaches to control infectious diseases such as the COVID-19 pandemic. Inactivated viral vaccines have a history of "vaccine-induced enhanced disease", which may occur when neutralizing antibodies bind to viral antigens without blocking or clearing the infection. This can cause additional inflammation through the mechanisms described for other respiratory pathogens and lead to acute respiratory distress syndrome. Since the structure and function of SARS-CoV-2 glycoproteins are well known, vaccine manufacturers appear to be careful when inactivating the virus to completely inactivate and maintain the viral epitopes necessary for protective immune induction. It seems that caution should be taken in the usage of inactivated vaccines in children to ensure they are safe and efficacious, vaccinated children should be well monitored and any symptoms should be reported immediately.

The economic implications of the COVID-19 outbreak on tourism industry: empirical evidence from Turkey

The novel coronavirus (COVID-19) pandemic has caused tremendous fear and uncertainty and affected health, economy, and social life in an unprecedented form worldwide. Yet, the level of knowledge on its economic implications is very limited. Therefore, it is of paramount importance to explain the health, social, and economic impacts of COVID-19. Because the tourism is one of the most affected industries by the pandemic, this study aims to explain the effects of COVID-19 cases and deaths, global fear, and government responses on Turkey's tourism industry. Empirical findings show that the tourism industry reacts negatively to new cases, number of deaths, and global fear measures. Also, government containment and health measures and economic supports positively affect the tourism industry. Furthermore, government stringency policies drive down the tourism industry's performance. The findings of this study provide significant implications for tourism and travel firms, policy makers, and future research.

Effect of synbiotics on inflammatory markers and white blood cell count in COVID-19 patients: a randomized, double-blind, placebo-controlled clinical trial. (Special Issue: The relationship between nutrition and COVID-19.)

Purpose: Today, coronavirus disease-19 (COVID-19) treatment is an evolving process, and synbiotic administration has been suggested as a new therapeutic strategy. This study aims to investigate the effect of synbiotic supplementation in COVID-19 patients. Design/methodology/approach: In this placebo-controlled trial, 80 patients were randomized to receive oral synbiotic capsule (containing fructooligosaccharide and seven bacterial strains;Lactobacillus (L) casei, L. rhamnosus, Streptococcus thermophilus, Bifidobacterium breve, L. acidophilus, Bifidobacterium longum, L. bulgaricus, each one 109 colony-forming units) or placebo for two months. Inflammatory markers (Interleukin-6 [IL-6], C-reactive protein [CRP], erythrocyte sedimentation rate [ESR]) and white blood cell (WBC) count were evaluated at two timepoints (baseline, two months later). The measured variables were adjusted for confounders and analyzed by SPSS v21.0. Findings: All 80 enrolled patients completed the study. The study adherence was good (approximately 70%). The mean changes for IL-6 were not significant ( = -0.6 +or- 10.4 pg/mL vs = +11.2 +or- 50.3 pg/mL, p > 0.05). There were no significant improvements for CRP, ESR and WBC. Originality/value: Administration of synbiotics for two months did not improve inflammatory markers in COVID-19 patients.

Educational needs of people in Mazandaran province about COVID-19 in 2020: an Internet-based study

Background and purpose: Considering the global spread of COVID-19, it seems that correct information obtained from reliable sources and training based on the need for self-care behaviors are useful solutions to reduce the harm caused by the disease. This study aimed at assessing the educational needs of people in Mazandaran province about COVID-19. Materials and methods: In a cross-sectional study, 1220 people were recruited via convenience sampling in 2020. A researcher-made questionnaire was administered and information such as demographic characteristics, disease condition, and educational needs for COVID-19 were recorded. Data were analyzed using descriptive statistics and parametric tests, correlation, analysis of variance, and t-test. Results: The mean age of the participants was 39.34 +or- 8.74. Educational level included diploma (42.5%) and university education (38.9%). About 73.3% of the participants were women. According to findings the main sources of information about COVID-19 were social networks (68.4%), satellite programs (20.9%), Ministry of Health notices (8.1%), national media (1.6%), other sources (0.6%), and family members (0.4%). Online methods were the most desirable educational methods (94.6%) reported by the people living in Mazandaran province. The overall mean score for educational needs was 3.89+or-0.96. The educational need for the disease (3.76+or-0.84) and self-care needs (4.03+or-1.07) indicated high needs for educational trainings and significant differences between these areas (P=001). Conclusion: In this study, social networks and media were the primary sources of information about COVID-19. Designing and implementing self-management and self-care training programs could improve the health of people in Mazandaran province and prevent the spread of COVID-19.

A research on the using of bank loans in accommodation companies traded in Borsa Istanbul

The main purpose of this research is to analyze the using of bank loans provided by the banking sector in accommodation companies traded in Borsa Istanbul in terms of type, maturity and cost. The study also examined the impact of the Covid-19 outbreak on the accommodation companies' use of bank loans. In this context, the level of bank loan usage, the type of bank loans, interest rates, maturity and their distribution in currency between the years 2009 and 2021 were tried to be determined by ratio and document analysis. As a result of the analysis, it was determined that 10,84% of the assets in accommodation companies are financed by bank loans, the use of bank loans in total liabilities is 19.92% and short-term bank loans are preferred. It was also detected that accommodation companies mainly benefit from business loans, daily spot loans, revolving loans, current account loans, foreign exchange earning loans, vehicle loans and investment loans in Turkish Lira, Dollar, Euro and Sterling with interest rates varying every year. However, compared to the pre-Covid-19 outbreak period, it was observed that the level of bank loans used by accommodation companies first decreased, but then increased again.

Scenarios of COVID-19 epidemic effects on socioeconomic and health status of Iran

Background and Objectives: The COVID-19 epidemic and its subsequent effects have become a significant global challenge. In addition to being affected by this crisis, Iran is also facing many other problems, including sanctions and economic problems. So, there is a concern that it will suffer more severe consequences. Methods: Scenario planning is one of the ways to recognize future changes and environmental uncertainties. This study used the so-called global business network (GBN) method, also known as the scenario matrix method. This method is based on two key uncertainties and six steps have been taken to examine variables related to health and socio-economic factors and use the opinions of relevant experts. Results: To be expected, Iran's health system will be able to manage the epidemic in the face of various conditions with severity and weakness, and only in the pessimistic scenario or in Worst-case scenario with the default assumption of the continuation of sanctions and the spread of the epidemic. It leads to global restrictions, loss of foreign exchange reserves, loss of performance or collapse of the health system, increasing the number of deaths and diminishing the quality of life. Conclusion: Regarding the COVID-19 epidemic and the existing background factors, scenarios of Iran's health and economic conditions were narrated. Given the ability of the scenarios to understand the complexity and help in decision-making, it is considered a useful tool for policy makers to have a broader, comprehensive and reasonable look to achieve a correct consensus. This situation leads to the preservation and continuation of society health and conventional economic decisions.

Comparison of laboratory parameters during herpes zoster infection: a case-control study

Objective: We aimed to find the parameters that can change during herpes zoster infection and observe the relationship of these parameters throughout the disease. Material and Methods: We compared 40 herpes zoster patients and 2 separate control groups, who were healthy and had comorbidities similar in age and gender. Patient files were retrospectively analyzed, and laboratory parameters were compared between groups. The laboratory values of the patient group with herpes zoster were evaluated among themselves according to the duration of the symptoms. Results: Fasting glucose, creatinine, aspartate aminotransferase values, the percentage and the absolute number of monocytes, red blood cell distribution width-coefficient of variation, and C-reactive protein levels of the patients with herpes zoster were significantly higher, and the absolute number of lymphocytes, mean corpuscular volume and platelet distribution width levels were lower than the control groups. The percentage of monocytes in the first 5 days was significantly higher than in the following days, and hematocrit values were lower in the last days. Conclusion: Examining routine laboratory values during diseases may help diagnose the disease, especially in patients with faint clinical signs and zoster sine zoster. In addition, it may be useful to question patients with herpes zoster for renal dysfunction, rheumatological diseases, and malignancy.

Association between diet quality and BMI with side effects of pfizer-biontech COVID-19 vaccine and SARS-CoV-2 immunoglobulin G titers. (Special Issue: The relationship between nutrition and COVID-19.)

Purpose: The nutritional and anthropometric status can be essential in determining their immune response to vaccines. The purpose of this paper was to investigate the association between diet quality and anthropometric indices with the side effects of the Pfizer-BioNTech COVID-19 vaccine and the SARS-CoV-2 immunoglobulin G titer among Kurdish adults. Design/methodology/approach: This cross-sectional survey-based study was conducted between December 2021 and February 2022. This paper included data on 115 adults, 20-89 years old, from the Kurdistan region. Dietary information was collected using a short food frequency questionnaire, and diet quality was assessed using a plant-based healthy diet score. A blood test was performed to measure the SARS-CoV-2 immunoglobin G (IgG) titer after the vaccination's first and second doses. Findings: Overweight and obese subjects reported more local pain, myalgia, headache, local bruising and local reactions after receiving the first dose of the vaccine (p = 0.04). People on a less healthy diet reported more local pain, myalgia and headache (p = 0.04) and more local bruising and reactions (p = 0.01) after receiving the second dose of the vaccine. On the other hand, the authors observed that those with healthy dietary habits had more IgG titer after the first and second doses of vaccination than those with less healthy dietary habits (p = 0.001). Originality/valueThe results showed that participants with a healthy diet and normal weight status had fewer side effects of the Pfizer-BioNTech COVID-19 vaccine than obese people and those with a less healthy diet.

Assessment of serum neopterin levels in patients hospitalized with severe COVID-19

Background: COVID-19 has caused a considerable number of hospital admissions in China since December 2019. Many COVID-19 patients experience signs of acute respiratory distress syndrome, and some are even in danger of dying. Background: to measure the serum levels of D-dimer, Neutrophil-Lymphocyte count ratio (NLR), and neopterin in patients hospitalized with severe COVID-19 in Baghdad, Iraq. And to determine the cut-off values (critical values) of these markers for the distinction between the severe patients diagnosed with COVID-19 and the controls. Materials and methods: In this case-control study, we collect blood from 89 subjects, 45 were severe patients hospitalized in many Baghdad medical centers who were diagnosed with COVID-19 infection, and 44 were apparently healthy subjects as a control. The time of collection is from September 15 th to December 31 th, 2021. The optimal cut-off points (critical values) and prognostic relevance of D-dimer, Neutrophil-Lymphocyte count ratio (NLR), and neopterin were investigated using (ROC) curves analysis. Results: In severe patients hospitalized with COVID-19 the levels of D-dimer, NLR, and neopterin were statistically significantly higher than in control participants (P < 0.005). The D-dimer, NLR, and neopterin tests have areas under the receiver operating characteristic (ROC) curves of 0.920, 0.90, and 0.74 respectively, and their critical values for the differentiation between the severe patients and control were 0.22 micro g/ml, 2.56, and 3.02 nmol/L. Conclusions: D-dimer, NLR, and neopterin levels in sever COVID-19 patients were higher than control, with values of greater than 0.22 micro g/ml, 2.56 and 3.02 nmol/L respectively was linked to a severe COVID-19 infection with good sensitivity and selectivity.

E-food trade effects on purchasing approach regarding customer behavior

Our world is changing too fast. The distances have been shortened and communication has been increased by the invention and widespread use of the internet. Our habits started to change in many aspects of our lives by the development of digitalization. Especially during the pandemic Covid-19 that has started at the end of 2019, it's observed that mobility of people have been decreased and however, they began to have difficulties in meeting the needs. There has been a great demand for companies that sell over the internet. In particular, the tendencies of people to purchase food items which are their vital need over the internet have increased to a great extent. Looking at the e-commerce market on a sectorial basis during the pandemic, the biggest increase was seen in e-food trade with a growth of approximately 400%. Within that period, it is predicted that our purchasing habits will change rapidly and virtual markets will become much more important in our lives. The delivery of food products to the consumer has always been a big problem. The risk of deterioration of the products in a short time and the physical destruction of the products during their transportation has increased the importance of food logistics. The logistics channels are needed to be developed in order to increase e-food trade. For this reason, contemporary logistics channels have started to be used by integrating developed logistics applications to the traditional logistics channels. It will be much faster and cost-efficient to deliver the products to the consumer with the new logistics channels in the near future. Yield penalty due to transportation will decrease, and since the number of stock brokers is reduced, the consumer will be able to reach the product they demand at a more affordable price from the producer that they have chosen. In the future, physical stores will be replaced by logistics-supported virtual markets. The agriculture and food sector should also start working in order to accommodate quickly to the new trade order.
