ABSTRACT
This study aims to understand the mechanisms of consumers' online grocery shopping (OGS) acceptance in the current COVID-19 pandemic. Through this perspective, an extended technology acceptance model is employed by including the fear of COVID-19 factor to reveal the extent of the Turkish consumers' acceptance of OGS. We have tested the proposed research model on 455 survey participants living in various cities of Turkey. Structural equation modeling is employed to test the eleven research hypotheses. The results indicate that perceived ease of use, perceived usefulness, and attitude are valid predictors of OGS acceptance. Besides, the fear of COVID-19 negatively moderates these relationships. By revealing these empirical results, this study provides some useful insights into our understanding of the acceptance mechanisms of OGS processes in a pandemic situation. We hope to pinpoint the underlying reasons for the vast expansion of OGS among Turkish customers in pandemic times. © 2022 The authors.
ABSTRACT
In this study, we present the ultrasound imaging features of lymph nodes arising in the regional lymph node chain after the first or second dose of the Pfizer-BioNTech COVID-19 vaccine. Ipsilateral lymphadenopathy adjacent to the vaccine injection site is an extremely rare but expected adverse reaction following COVID-19 vaccination. Although axillary lymphadenopathy is more common, cases of supraclavicular lymphadenopathy have also been reported after widespread vaccination against COVID-19. Ultrasonography examinations were performed on seven patients with no previous pathological conditions, who presented to our radiology department after receiving the Pfizer-BioNTech COVID-19 vaccine. Bilateral axillary, supraclavicular and subclavicular lymph node stations were explored. These patients typically present with enlarged hypoechoic lymph nodes with the loss of fatty hilum, asymmetric or diffuse cortical thickening, and increased hilar and cortical vascularization on the color doppler ultrasonography of the ipsilateral axillary and supraclavicular regions. Radiologists and clinicians should be aware of the ultrasonographic features of these lymph nodes and should inform the patient that these lymph nodes are often a self-limiting process. Thus, unnecessary axillary lymph node biopsies should be avoided, and patients should be treated conservatively.
ABSTRACT
COVID-19 has caused many radical changes in our daily life. The main purpose of this study is to examine the impact of the pandemic on household behavior and waste changes in the largest city of Turkey, Istanbul. Research data were collected from 946 participants in the period May to December 2020 through an online survey, and frequency and logistic regression analyses were conducted. Frequency analysis of the data showed that mask, glove, disposable bag usage, cooking at home, online shopping, home delivery, dishwasher and washing machine usage increased, while ordering food from outside decreased. In line with these behavioral changes, we found that medical, food, disposable bag and plastic wastes generated by the sampled households increased as well. We then conducted logistic regression analysis to examine the correlation between changes in household behavior and waste disposal and the income and size of households during this pandemic period. The empirical findings highlight the importance of developing special management strategies for medical, food and plastic wastes and for households with different socio-economic backgrounds to reduce the unsustainable environmental impact of COVID-19. © 2022, Bentham Science Publishers.

ABSTRACT
Coronavirus disease (COVID-19) is a major health crisis with more than 100 million cases and almost 3 million deaths having been reported to date. According to the World Health Organization (WHO), vaccination of the majority of the global population is the most critical strategy to return to normal. Vaccines are approved following meticulous work regarding safety and efficacy;however, very little attention is paid to the injection itself. Shoulder injury related to vaccine administration (SIRVA) is a complication due to erroneous injection. SIRVA can be easily prevented, and with millions of people now having COVID-19 vaccine injections, it is crucial to be aware of this complication. In this article, it was aimed to present 2 cases of SIRVA developing secondary to COVID vaccine injection. In the first case, a 30-year-old female presented with pain and limitation of movement in the right shoulder joint. Her complaints started within the first 24 hours following the COVID vaccine. In MRI examination, bursitis and bone marrow edema were present. In the second case, a 53-year-old female had a painful shoulder joint. Her complaints started approximately one day after the COVID vaccine, similar to the first case, bursitis was observed in the MRI.
