Russian adolescent mental health in 2002, 2015 and during the COVID-19 pandemic in 2021.

BACKGROUND: Adolescent mental health is a global concern, however, time trends and the COVID-19-related restrictions vary across countries. This study examined changes in adolescent mental health and substance use in Russia between 2002, 2015 and during the pandemic in 2021. METHODS: Cross-sectional school-based surveys of 12- to 18-year-olds were carried out in a Siberian city in 2002 (N = 713), 2015 (N = 840) and 2021 (N = 721) using the Strengths and Difficulties Questionnaire, data on tobacco, alcohol and drug use and socio-demographic information. We examined the effect of cohort, gender, family composition and parental occupation on mental health and substance use. RESULTS: There were increases in emotional symptoms and internalising problems (B = 0.93, p < .001) and decreases in substance use over 19 years (B = -.73, p < .001). Changes in adolescent mental health and substance use were substantial from 2002 to 2015 and nonsignificant from 2015 to 2021. Increases in mental health problems were evident only among girls; a decrease in alcohol use was larger among boys. Family composition and parental occupation did not account for these changes. CONCLUSIONS: These results suggest that the mental health of Russian adolescent girls has worsened in the 21st century; the gender gap in mental health has widened; the gender gap in alcohol use was reversed in 2021. The findings highlight the need for research into gender-specific factors and for effective interventions. The lack of changes in Russian adolescent mental health and substance use from 2015 to during the pandemic in 2021 suggests successful coping; however, more research is needed.

Emergency room imaging findings in patients presenting after COVID-19 vaccination.

Objectives: Data on potential side effects of COVID-19 vaccines remains limited. This study aims to evaluate the relationship between the clinical presentations and imaging findings of emergency room (ER) patients presenting with suspected side effects or complications of recent COVID-19 vaccination. Materials and Methods: An Institutional Review Board-approved retrospective analysis of vaccinated patients who underwent imaging studies in the ER between December 2020 and August 2021 was conducted. Reports were analyzed for imaging modality, chief complaints, and imaging findings. Results: A total of 173 studies on 161 patients were included: 73 X-rays, 57 computed tomographys, 12 magnetic resonance imagings, and 31 ultrasounds. Analysis of the 168 reports dictated in these 173 studies revealed chest pain (27%), shortness of breath (17%), headache (12.5%), fever (10%), and cough (11.9%) as the most common presenting signs/symptoms. About 57.7% of reports showed no post-vaccine complications. Of the 42.3% of reports with findings, lung opacities/consolidation (36.6%) and cervical and/or axillary adenopathy (35.2%) were most commonly seen; other major findings included saddle embolus (1.4%) and vertebral artery occlusion (1.4%). Conclusion: Chest pain, cough, shortness of breath, and headache were the most common presenting symptoms in the ER after COVID-19 vaccination, and chest X-ray and computed tomography chest angiography were the most commonly ordered studies to assess vaccine-related complications. Lung opacities/consolidations were the most common findings. Given that vascular post-vaccine complications are considered the most dangerous and 2.8% of reports demonstrated positive vascular findings, concern for vascular complications should initiate appropriate imaging to ensure prompt diagnosis and management.

Understanding mobile payment continuance intention on mobile food ordering apps (MFOAs) during COVID-19 Pandemic

Mobile Food Ordering Application (MFOAs) has driven growth during the COVID-19 pandemic in Indonesia. The research goals were to examining variables of mobile payment continuance intention on MFOAs during this phenomenon. Authors chose PLS-SEM as study research with a judgment sampling approach for gaining data and Smart PLS version 3.0 as a statistical tool. The research model is developed based on ECM and TAM by integrating security and trust as an extended variable. The study result is based on 400 respondents from October - November 2020 who are active using non-bank mobile payment in Jabodetabek area and city of Bandung. Data was collected using purposive sampling and use Smart PLS as a tool for the research SEM model. In this research, all five variables indicate a significant impact on the Continuance Intention variable through trust. The Ease of Use variable has the most considerable influence on usefulness than the other variables. The Usefulness variable also has a significant impact on continuance intention through satisfaction. © 2021 IEEE.

Predicting the determinants of continuance intention to use e-wallet in indonesia post-covid-19 pandemic

Digital payment, such as e-wallet, is not unfamiliar in Indonesia;the number of e-wallet usage has constantly been growing in these past years and is expected to overtake bank transfers in the future. With the increasing usage of e-wallet, the payment method trend is slowly shifting, leaving the cash method behind. Nevertheless, since the COVID-19 pandemic starts in the year 2020, it shifts to accelerate the circumstances of e-wallet usage differ from the typical situations. This study dwells on predicting determinants of continuous intention to use e-wallet post-COVID-19 pandemic by using PLS-SEM. With the purposive sampling method, data was gathered via an online questionnaire from 483 respondents in October-November 2020, consisting of e-wallet users located in Jakarta, Bogor, Depok, Tangerang, and Bandung. In this model, Attitude, Inertia, Subjective Norm, and Trust are variables influencing continuance intention, while Satisfaction is the variable affecting Inertia. All hypotheses are found to be significant. © 2021 IEEE.

Multisystem Imaging Manifestations of COVID-19, Part 2: From Cardiac Complications to Pediatric Manifestations.

Infection with severe acute respiratory syndrome coronavirus 2 results in coronavirus disease 2019 (COVID-19), which was declared an official pandemic by the World Health Organization on March 11, 2020. COVID-19 has been reported in most countries, and as of August 15, 2020, there have been over 21 million cases of COVID-19 reported worldwide, with over 800 000 COVID-19-associated deaths. Although COVID-19 predominantly affects the respiratory system, it has become apparent that many other organ systems can also be involved. Imaging plays an essential role in the diagnosis of all manifestations of the disease and its related complications, and proper utilization and interpretation of imaging examinations is crucial. A comprehensive understanding of the diagnostic imaging hallmarks, imaging features, multisystem involvement, and evolution of imaging findings is essential for effective patient management and treatment. In part 1 of this article, the authors described the viral pathogenesis, diagnostic imaging hallmarks, and manifestations of the pulmonary and peripheral and central vascular systems of COVID-19. In part 2 of this article, the authors focus on the key imaging features of the varied pathologic manifestations of COVID-19, involving the cardiac, neurologic, abdominal, dermatologic and ocular, and musculoskeletal systems, as well as the pediatric and pregnancy-related manifestations of the virus.

Multisystem Imaging Manifestations of COVID-19, Part 1: Viral Pathogenesis and Pulmonary and Vascular System Complications.

Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) results in coronavirus disease 2019 (COVID-19), which was declared an official pandemic by the World Health Organization on March 11, 2020. The infection has been reported in most countries around the world. As of August 2020, there have been over 21 million cases of COVID-19 reported worldwide, with over 800 000 COVID-19-associated deaths. It has become apparent that although COVID-19 predominantly affects the respiratory system, many other organ systems can also be involved. Imaging plays an essential role in the diagnosis of all manifestations of the disease, as well as its related complications, and proper utilization and interpretation of imaging examinations is crucial. With the growing global COVID-19 outbreak, a comprehensive understanding of the diagnostic imaging hallmarks, imaging features, multisystemic involvement, and evolution of imaging findings is essential for effective patient management and treatment. To date, only a few articles have been published that comprehensively describe the multisystemic imaging manifestations of COVID-19. The authors provide an inclusive system-by-system image-based review of this life-threatening and rapidly spreading infection. In part 1 of this article, the authors discuss general aspects of the disease, with an emphasis on virology, the pathophysiology of the virus, and clinical presentation of the disease. The key imaging features of the varied pathologic manifestations of this infection that involve the pulmonary and peripheral and central vascular systems are also described. Part 2 will focus on key imaging features of COVID-19 that involve the cardiac, neurologic, abdominal, dermatologic and ocular, and musculoskeletal systems, as well as pediatric and pregnancy-related manifestations of the virus. Vascular complications pertinent to each system will be also be discussed in part 2. Online supplemental material is available for this article. ©RSNA, 2020.
