RESUMO

OBJECTIVE: Onset of the Coronavirus Disease 2019 (COVID) pandemic has increased students' perceived burdens. The current study aimed to examine COVID-related changes and to identify potential factors that contribute to students' stress. METHOD: Adopting a cross-sectional cohort-study design, we examined perceived stress and depressive and anxiety symptoms with a specific focus on the role of study-related variables such as perceived study-related demands, study-related resources, academic procrastination, and stress-enhancing beliefs. Two cohorts (Npre-COVID = 2,175; NCOVID = 959) were recruited at the same university and matched with regard to their propensity score (age, gender, semester). RESULTS: Compared with the pre-COVID cohort, university students in the COVID cohort reported more perceived stress, more depressive and anxiety symptoms, more academic procrastination due to fear of failure, more stress-enhancing beliefs, more distress due to the housing situation, and more perceived study-related challenges (Cohen's d = 0.15-0.45). A stepwise regression analysis identified depressive symptoms, procrastination due to fear of failure, general self-efficacy, increased study demands, perceived difficulties with self-organized learning, distress due to housing, and stress-enhancing beliefs as predictors of perceived stress in the COVID cohort. DISCUSSION: Findings suggest that the switch to online-only education increased the study-related burden for students, primarily due to exams being replaced by a greater amount of regular coursework and imposing demands on self-organized learning. Possibly, stress-enhancing beliefs and procrastination due to fear of failure might have been elevated due to less opportunity for social referencing and lack of felt social support by peer students. CONCLUSION: Experienced increased burden in students during the COVID pandemic was mostly accounted for by a lack of perceived individual resources rather than by an increase in objective study-related demands.

RESUMO

PURPOSE: The COVID-19 pandemic has led to changes in global health care. Medical societies had to update guidelines and enhance new services such as video consultations. Cancer treatment had to be modified. The aim of this study is to ensure optimal care for cancer patients with the help of high-quality training even in times of crisis. We therefore conducted a nationwide survey of physicians in training in oncological disciplines during the pandemic to assess the impact on their education. METHODS: The survey was sent to tumour centres, hospitals, specialist societies, and working and junior research groups and distributed via newsletters and homepages. Interim results and a call for participation were published as a poster (DEGRO) [26] and in the German Cancer Society (DKG) journal FORUM [42]. The survey contained 53 questions on conditions of education and training and on clinical and scientific work. Statistics were carried out with LimeSurvey and SPSS (IBM Corp., Armonk, NY, USA). RESULTS: Between February and November 2022, 450 participants answered the survey, with radio-oncologists being the largest group (28%). Most colleagues (63%) had access to digital training methods. Virtual sessions were rated as a good alternative, especially as multidisciplinary meetings (54%) as well as in-house and external training programs (48%, 47%). The time spent by training supervisors on education was rated as less than before the pandemic by 57%. Half of all participants perceived communication (54%), motivation (44%) and atmosphere (50%) in the team as bad. The participants felt strongly burdened by extra work (55%) and by a changed team atmosphere (49%). One third felt a change in the quality of training during the pandemic and rated it as negative (35%). According to 37% of the participants, this had little influence on their own quality of work. Additional subgroup analyses revealed significant differences in gender, specialty and education level. CONCLUSION: In order to improve oncology training in times of crisis, access to digital training options and meetings should be ensured. Participants wish for regular team meetings in person to enable good team spirit, compensation for overtime work and sufficient time for training supervisors for discussion and feedback.

RESUMO

BACKGROUND: Both COVID-19 and its associated societal restrictions have affected individuals' health and everyday life. In Sweden, more lenient public health restrictions were implemented, with individuals asked to act responsibly in terms of reducing spread of disease. The majority of studies reporting on experiences of Covid-19 restrictions have been in the context of more substantial mandatory rules aimed at reducing social contact, therefore it is important to describe how more lenient restrictions have impacted individuals' well-being. This study aims to describe perceptions of everyday life during the first wave of the COVID-19 pandemic, perceived by individuals with no underlying medical condition, and living with more lenient public health restrictions in Sweden. METHOD: The participants were recruited from individuals who originally had participated in an online survey about life satisfaction, health, and physical activity. Fifteen individuals (median age 49, range 26-76 years, seven women) in various social situations, such as living alone/cohabiting, having children at home, geographical area and size of city were interviewed. Qualitative content analysis was applied to the data. RESULTS: An overall theme "Both hindrances and opportunities in important life domains were experienced within the same person during lenient Covid-19 restrictions" was derived and covered three categories: "New possibilities of flexibility in work and better health", "Life went on as usual with minor adjustments" and "Everyday life changed and became more difficult" together with eight subcategories. For most participants, both facilitating and hindering important domains in life were described. Unexpected findings were positive experiences regarding working from home, physical activities, leisure time activities and the balance between work and leisure time. In areas where only minor adjustments were made, life was perceived as going on as before. On the other hand, restrictions increased worries and were perceived to have negative effects on social participation. CONCLUSION: The impact of the pandemic and lenient restrictions in Sweden on the participants´ everyday life was multifaceted. Both hindrances and opportunities in important life domains were experienced within the same person. An increased flexibility in work- and leisure activities were perceived having positive effects for health and wellbeing and led to a better balance in life.

RESUMO

Care for family carers of people with dementia in municipal communities during the pandemic: A Qualitative Study Abstract: Background: The availability of support services for family carers of persons with dementia in the municipal community shows deficits due to the Corona pandemic and thus entails a change in the support of carers. Research question: The questions arise, what changes in the care of family carers of people with dementia do those affected perceive, how do actors from the municipal community experience the care situation during the pandemic and to what extent do the perceptions of the groups coincide or differ. Method: The database consists of town hall talks and focus groups from 13 municipal communities in Germany. Participants were family carers and actors from the municipal community. For data analysis, a qualitative content analysis was carried out. Result: Negative changes in the care of caregivers can be seen, for example, in the omission of care services or groups of relatives. Above all, actors perceived positive changes, such as advancing digitalization or increased neighborly help. The perception of changes in the care situation differs in several subcategories between carers and actors. Conclusion: Although large gaps in care have been created by the pandemic, emerging challenges also create new ways for support such as digital groups for family carers. In the future, opportunities need to be created to implement already developed interventions in such a way that the target group can make use of them.

RESUMO

This study examines the COVID-19 vulnerability and subsequent market dynamics in the volatile hospitality market worldwide, by focusing in particular on individual Airbnb bookings-data for six world-cities in various continents over the period January 2020-August 2021. This research was done by: (i) looking into factual survival rates of Airbnb accommodations in the period concerned; (ii) examining place-based impacts of intra-city location on the economic performance of Airbnb facilities; (iii) estimating the price responses to the pandemic by means of a hedonic price model. In our statistical analyses based on large volumes of time- and space-varying data, multilevel logistic regression models are used to trace 'corona survivability footprints' and to estimate a hedonic price-elasticity-of-demand model. The results reveal hardships for the Airbnb market as a whole as well as a high volatility in prices in most cities. Our study highlights the vulnerability and 'corona echo-effects' on Airbnb markets for specific accommodation segments in several large cities in the world. It adds to the tourism literature by testing the geographic distributional impacts of the corona pandemic on customers' choices regarding type and intra-urban location of Airbnb accommodations.

RESUMO

Many people relied on their faith as one resource in order to cope during the COVID-19 pandemic. In Germany, between the eighteen months from June 2020 to November 2021, different participants at different times were assessed during different phases of the COVID-19 pandemic. The total sample of this continuous cross-sectional survey consisted of 4,693 participants. Analyses revealed that with the 2nd wave of the infection and its 2nd lockdown, trust in a Higher Source, along with praying and meditation decreased. Also, the sharp increase in corona-related stressors was associated with a decline of wellbeing and a continuing loss of faith. These developments were observed in both Catholics and Protestants, and in both younger and older persons. In addition, the long phases of insecurity and social isolation lacking the significant support usually given by religious communities may have likewise challenged the religious-coping capacities of religious/spiritual people themselves.

RESUMO

The emergence of more transmissible or aggressive variants of SARS-CoV-2 requires the development of antiviral medication that is quickly adjustable to evolving viral escape mutations. Here we report the synthesis of chemically stabilized small interfering RNA (siRNA) against SARS-CoV-2. The siRNA can be further modified with receptor ligands such as peptides using CuI -catalysed click-chemistry. We demonstrate that optimized siRNAs can reduce viral loads and virus-induced cytotoxicity by up to five orders of magnitude in cell lines challenged with SARS-CoV-2. Furthermore, we show that an ACE2-binding peptide-conjugated siRNA is able to reduce virus replication and virus-induced apoptosis in 3D mucociliary lung microtissues. The adjustment of the siRNA sequence allows a rapid adaptation of their antiviral activity against different variants of concern. The ability to conjugate the siRNA via click-chemistry to receptor ligands facilitates the construction of targeted siRNAs for a flexible antiviral defence strategy.

RESUMO

The corona pandemic changed the lives of people in Germany in 2020. Completely new challenges had to be met in outpatient care and of course also in rheumatology practices. The rapid development, the constant changes, the readjustment, the accompaniment of patients and staff team in this global catastrophe are described. The influence on the daily work and the implementation of new scientific knowledge, e.g. the recommendations of the German Society of Rheumatology (DGRh), are reported. Experiences and insights into what can be learned and taken away from crisis situations are outlined. A detailed chronology of the events, taking the special rheumatological features into account, completes this report of experiences.

RESUMO

Neurological diseases are the most common cause of disability worldwide. In addition to physical limitations, they often lead to cognitive deficits that make active participation in professional and social life difficult. Due to physical and cognitive deficits, it is often difficult for neurological patients to gain access to specialized knowledge or to receive specialized treatment and is associated with greatly increased effort. Neurological diseases account for 11.6% of global disability-adjusted life years (DALYs, a measure for quantifying disease burden) and 16.5% of deaths, and remain the leading cause of DALYs and the second leading cause of death worldwide. Neurorehabilitation encompasses the goal of reintegrating patients with neurological dysfunctions into everyday life. The ongoing situation in the context of the COVID-19 pandemic poses new challenges for the healthcare system. Social distancing and quarantine have deprived many people with neurological disorders of access to routine medical care. The corona pandemic is a catalyst for the widespread use of telemedicine in the field of neurology and neurorehabilitation. Projects such as the Brunei project of the Nordwest Krankenhaus Frankfurt as well as an MS clinic in Canada show that highly specialized medicine and neurorehabilitation can be delivered to remote areas or in the living room of patients or any doctor's office. Telemedical, telerehabilitative and teletherapeutic applications offer the opportunity to supplement and optimize existing care structures and with modern technology to make a new and contemporary interpretation of old-fashioned medical and therapeutic home visits.

RESUMO

The COVID-19 pandemic has confronted mathematics teachers with the challenge of developing alternative teaching practices-in many cases at a distance through digital technology-because schools were closed. To investigate what distance practices in secondary mathematics education have emerged and how teachers experienced them, we set out online questionnaires in Flanders-the Dutch-speaking part of Belgium-, Germany, and the Netherlands. The questionnaire focused on teaching practices, teacher beliefs, didactics, and assessment. Data consisted of completed questionnaires by 1719 mathematics teachers. Results show that the use of video conferencing tools increased massively, while the use of mathematics-specific tools that teachers used before the lockdown reduced substantially. Further findings are that teachers' confidence in using digital technologies increased remarkably during the lockdown and that their experiences and beliefs only marginally impacted their distance learning practices. Also, we observed some differences between the three countries that might be explained by differences in educational policies and in technological facilities and support. For future research, it would be relevant to investigate long-term changes in teachers' practices, as well as students' views and experiences related to the teacher's practices.

RESUMO

BACKGROUND: During the peak times of the COVID-19 pandemic, which were characterized by contact restrictions, many companies initiated telework for their employees due to infection prevention. OBJECTIVE: In this literature review working from home and therefore digital cooperation in a virtual team was investigated, focusing on the organization of occupational health promotion aspects in the context of prevention of social isolation. RESULTS: The current occupational health psychology research identified appropriate and enriched information and communication media accompanied by sufficient and understandable technical support as basic prerequisites for the collaboration of location-independent teams. Also, a continuous socially supporting communication within the team and with the supervisor as well as health-promoting leadership have a positive impact on the employees' mental health. Additionally, individual (digital) health promotion interventions and flexible working hours are recommended. CONCLUSION: These multifactorial approaches to measures derived from the literature are suggested for companies with employees working predominantly from home to reduce work-related adverse health effects from the crisis, especially with respect to social isolation and to promote their employees' health.

RESUMO

The COVID-19 pandemic has caused massive restrictions on public life. A survey of more than 1500 local councilors showed that councils at the local level are restricted in their capacity. After a total lockdown in March 2020 at the local level, the local central committee (Hauptausschuss) took over, substituting for and representing the full city council's local decision-making capacity. Later on, in some cities, councils were able to implement council meetings with half of the councilors. In this "executive hour," several local committees and commissions as well as political events organized by the civil society could not be implemented.Before the local elections on September 22 in North Rhine-Westphalia, the pandemic affected the registration of political parties, which became problematic. Appropriate space, as well as digital infrastructure, was lacking. With more mitigated COVID-19 restrictions and new regulations for local elections by the province of North Rhine-Westphalia, electoral party registration was facilitated, and deadlines were extended. In particular, smaller political parties and new candidates for the mayoral direct election experienced problems in presenting themselves during electoral campaigns; new parties and candidates were often disadvantaged compared with the political incumbent and the established political parties.Furthermore, electoral street campaigning, panel discussions, and canvassing were extremely limited. In this time of "forced digitization," the established political parties in particular were able to focus on e­campaigning. Because of these disadvantages, smaller parties requested postponement of the local elections. The majority in all political parties refused postal voting.

RESUMO

BACKGROUND: During the COVID-19 pandemic, most people had to cope with the restrictions of the lockdown, leaving them to their fears, insecurity and isolation. On the other hand, due to the unexpected 'extra time' there was room for new experiences and for personal reflections on what is essential in life, to perceive nature and relations more consciously etc. We, therefore, intended to analyze perceived changes of attitudes and behaviors during the time of lockdown, and whether these perceptions would contribute to personal wellbeing during the pandemic. METHODS: An anonym cross-sectional online survey was performed for data collection, using standardized questionnaires, i.e., the WHO-Five Well-being Index (WHO-5), Brief Multidimensional Life Satisfaction Scale (BMLSS), Awe/Gratitude scale (GrAw-7), and the newly developed Perceived Changes Questionnaire (PCQ). RESULTS: Within the number of respondents (n = 1277), women were predominating (67.5%). Participants' mean age was 50.9 ± 14.9 years. Exploratory factor analyses showed that the 24-item Perceived Changes Questionnaire differentiated five factors that would account for 61% of variance: (1) Nature/Silence/Contemplation (Cronbach's alpha = .87), (2) Spirituality (Cronbach's alpha = .83), (3) Relationships (Cronbach's alpha = .80), (4) Reflection on life (Cronbach's alpha = .74), (5) Digital media usage (Cronbach's alpha = .74). Strongest changes were observed for Relationships and Nature/Silence/Contemplation. Perceived changes were stronger among older persons, among persons with higher wellbeing, and among those who relied on their faith as a resource. These changes were predicted best by a person's perception of wondering awe in distinct situations with subsequent feelings of gratitude. Stepwise regression analyzes revealed that participants' wellbeing was explained best by low perceived burden and high life satisfaction (R2 = .46). Awe/gratitude, perceived changes in terms of Nature/Silence/Contemplation and low Reflections of live are further variables that would predict a person's wellbeing among the COVID-19 pandemic. CONCLUSIONS: During the Corona pandemic, people tried to find ways to adapt to the outcomes of the restrictions. The perceived changes of attitudes and behaviors can be interpreted in terms of a reappraisal strategy. These can be measured with the extended version of the PCQ which was found to have good quality indices and a plausible factor structure. The reported changes contribute to persons' wellbeing only to some extend, indicating that they represent an independent quality of relevance in peoples' life.

RESUMO

The corona pandemic has led to a number of restrictions and prohibitions, which in turn place large psychosocial or spiritual burdens on patients with COVID-19, their families and relatives and the treating personnel in the healthcare system. Patients with COVID-19 are not allowed to receive visitors and many hospitals and nursing homes have completely banned visitors. Many support services have been reduced or stopped completely. Necessary treatment interventions for other patients with critical and life-limiting diseases have been delayed or suspended in order to free resources for the expected COVID-19 patients; however, these people need to feel social connectedness with their relatives. Palliative care patients should be exempted from any ban on visitors. Families should be able to visit dying patients even on intensive care units or isolation wards, using adequate protective equipment. Alternative options, such as video telephone calls or via social media should be explored for patients in isolation. Families should also be enabled to say goodbye to the deceased with adequate protective equipment or should be offered alternative real or virtual options for remembrance and commemoration. Health care professionals coping with the exceptional stress should be continuously supported. This requires clear communication and leadership structures, communication training, psychosocial support, but most of all optimal framework conditions for the clinical work.

RESUMO

Health care and especially care of the elderly have come under massive pressure from the corona pandemic. Structural deficits and weak points that are not really new are now more apparent because COVID-19 has brought these back into focus. In the entire healthcare system new questions arise in the face of the current challenges. Problems and gaps now become obvious in the health care services and in the provision of care for the elderly-some of them specifically related to one area, but to a greater extent these are cross-sectoral. Based on relevant national and international studies and publications and from the perspective of social gerontology, this article focuses on the current situation in the 'long-term nursing care in Germany' in the context of the SARS-CoV­2 virus. The results of this analysis are used to derive and outline what a new professional orientation can look like with a view to the future and what possible knowledge can be gained from the corona pandemic.

RESUMO

The People's Bank of China (PBoC) has implemented numerous measures to cushion the impacts of the COVID-19 health crisis on the Chinese economy. Since the current monetary policy framework features a multi-instrument mix of liquidity tools and pricing signals, we employ a dynamic-factor modelling approach to derive a composite indicator of China's monetary policy stance. Our quantitative assessment shows that the PBoC's policy response to the outbreak of the COVID-19 pandemic has been swift and decisive. Specifically, our estimates reveal that the PBoC has implemented novel policy measures to ensure that commercial banks maintain liquidity access and credit provision during the COVID-19 crisis.

RESUMO

Currently Covid-19 pandemic is a leading challenge across the globe. It is mandatory to attain and maintain good nutritional status to fight against virus. Nutritional status of individual is affected by several factors such as age, sex, health status, life style and medications. Nutritional status of individuals has been used as resilience towards destabilization during this COVID-19 pandemic. Optimal nutrition and dietary nutrient intake impact the immune system, therefore the only sustainable way to survive in current context is to strengthen the immune system. There is no evidence found that supplement can cure the immune system except Vit C, which is one of the best way to improve immune system. A proper diet can ensure that the body is in proper state to defeat the virus. However along with the dietary management guidelines the food safety management and good food practices is compulsory. This article explores the importance of nutrition to boost immunity and gives some professional and authentic dietary guidelines about nutrition and food safety to withstand COVID-19.

RESUMO

Exposure to ultrafine particles has a significant influence on human health. In regions with large commercial airports, air traffic and ground operations can represent a potential particle source. The particle number concentration was measured in a low-traffic residential area about 7 km from Frankfurt Airport with a Condensation Particle Counter in a long-term study. In addition, the particle number size distribution was determined using a Fast Mobility Particle Sizer. The particle number concentrations showed high variations over the entire measuring period and even within a single day. A maximum 24 h-mean of 24,120 cm-3 was detected. Very high particle number concentrations were in particular measured when the wind came from the direction of the airport. In this case, the particle number size distribution showed a maximum in the particle size range between 5 and 15 nm. Particles produced by combustion in jet engines typically have this size range and a high potential to be deposited in the alveoli. During a period with high air traffic volume, significantly higher particle number concentrations could be measured than during a period with low air traffic volume, as in the COVID-19 pandemic. A large commercial airport thus has the potential to lead to a high particle number concentration even in a distant residential area. Due to the high particle number concentrations, the critical particle size, and strong concentration fluctuations, long-term measurements are essential for a realistic exposure analysis.

RESUMO

Previous studies show that the QAnon conspiracy theory is especially popular among American evangelical Christians. The paper investigates the reasons behind this relationship. We hypothesize a mediation relationship between evangelical dogma and how it is practiced on the one hand and the susceptibility for conspiracy thinking on the other hand. We argue that evangelicalism due to its biblicism is characterized by the belief that its perception of reality holds absolute truth (nomization), that the world can be clearly divided into good and evil (Manichaeism), and that salvation can be achieved through political means (immanent eschatology). Those beliefs, in turn, in the uncertain times of the Covid crisis resonate with the cognitive (epistemic), the affective (moral), and conative (eschatological) elements of conspiracy theories. Using data of waves 46 (March 2019), 68 (April 2020), and 73 (September 2020) of the American Trends Panel, conducted by the PEW Research Center we show respective mediation effects: Evangelical Christians are particularly convinced that their religion alone holds absolute truth and that religion has not enough influence on politics. The latter also correlates with the conspiracy belief that "powerful people intentionally planned the Covid outbreak". QAnon support again is linked both to such Covid related conspiracy thinking and the three elements of nomization, Manichaeism, and immanent eschatology.

RESUMO

BACKGROUND: Due to the corona pandemic, face-to-face teaching was no longer permitted in the summer semester 2020 and online alternatives were quickly found. OBJECTIVE: In our article, we illustrate the switch from face-to-face to online teaching in ophthalmology at the University of Lübeck and compare online teaching with face-to-face teaching. METHODS: The central teaching evaluation takes place every semester with a standardized questionnaire. Based on the evaluation of these questions, a direct comparison of the attendance semester of the winter semester 2019/2020 with the online semester of the summer semester 2020 was carried out. RESULTS: The structure (p = 0.003), the organization (p = 0.001), the resources made available (p = 0.034), the attendance of the lectures (p < 0.001) and further dates (p = 0.041), the increase in interest (p = 0.039) and learning (p = 0.001) were rated better in the online semester than in the face-to-face semester. Overall, the digital summer semester 2020 (p < 0.01) received a significantly better overall grade than the face-to-face semester in winter 2019/2020. CONCLUSION: The structure of our courses has also been proven online. The theoretical content could be excellently mediated; however, practical exercises are not possible online. For the learning of practical skills, face-to-face instruction is still necessary.
