Effects of the COVID-19-induced lockdown period on general well-being, perceived stress and activity levels in the Faroe Islands.

AIMS: Detrimental effects on health and well-being were reported during the COVID-19-induced lockdown periods in several countries, but these associations have not been studied in small-scale island societies. This study aimed to examine the lockdown period's impact on general well-being, perceived stress and activity levels in the Faroe Islands. METHODS: We used cross-sectional data from two extensive population-based surveys of the general health conducted in November 2019 (the pre-COVID survey; n=2906), and four to six weeks into the first national lockdown (the lockdown survey; n=1204). RESULTS: A larger proportion of participants in the lockdown survey versus pre-COVID survey displayed excellent/very good self-rated health (68.1% vs. 62.0%; p<0.001), and the same pattern was observed for reporting good quality of life (85.7% vs. 82.7%; p<0.05). These associations remained statistically significant in a logistic regression model after adjusting for characteristics for which varying impact of the pandemic has been shown. Indicators of health behaviour showed that larger proportions of participants kept active during the lockdown survey versus pre-COVID survey, and these differences were statistically significant for physical, mental and spiritual activities (p<0.001). On the other hand, similar stress levels in the pre-COVID/lockdown periods were observed, but stratified analysis showed that participants with a high-stress level displayed better self-rated health in the lockdown period compared to the pre-COVID period (p=0.001). CONCLUSIONS: Findings indicate that self-reported health and quality of life improved during the early phase of the COVID lockdown, and individuals reported higher activity levels associated with good mental health during the COVID-19-induced lockdown period.

COVID-19 vaccination in patients with primary immunodeficiencies: an international survey on patient vaccine hesitancy and self-reported adverse events.

Introduction: The Sars-CoV-2 pandemic caused great concern for this novel virus among patients with primary immunodeficiency (PID) or inborn errors of immunity (IEI) and their families. When COVID-19 vaccination program started, no data existed on adverse events (AEs) in this particular patient population, nor if patients felt hesitancy being vaccinated. Objectives: To explore i) reasons for COVID-19 vaccination hesitancy, ii) the number and symptoms of AEs and their severity, durability and management. Method: The organisations International Patient Organisation for Primary Immunodeficiencies (IPOPI), European Society for Immunodeficiencies (ESID) and International Nursing Group for Immunodeficiencies (INGID) distributed a global self-administered online survey. Results: The survey was completed by 1317 patients (mean 47, range 12-100, years) from 40 countries. 41.7% of the patients denoted some hesitancy to COVID-19 vaccination, mainly having doubts about postvaccination protection related to their underlying PID and concerns about negative long-term effects. More women (22.6%) reported "very" or "pretty much" hesitancy compared to men (16.4%) (P<0.05). The most common systemic AEs were fatigue, muscle/body pain and headache, usually the same day or the day after the vaccination and lasting for 1-2 days. 27.8% of the respondents reported severe systemic AEs after any dose of COVID-19 vaccine. Only a minority (7.8%) of these patients visited a health-care professional and 20 patients (1.5%) were hospitalized or seen at emergency room without specifying subsequent admission at the hospital. Significantly more local and systemic AEs were reported after the second dose. No differences regarding AEs were observed across different PID subgroups or vaccine types. Conclusion: At the time of the survey, almost half of the patients reported having felt hesitancy to COVID-19 vaccination highlighting the importance and need of developing joint international guidelines and education programs about COVID-19 vaccination. The types of AEs were comparable to healthy controls, but more frequent AEs were reported. Clinical studies and prospective, detailed registration of AEs related to COVID-19 vaccines in this patient population is of great importance. It is crucial to elucidate whether there is a coincidental or causal association between COVID-19 vaccine and some severe systemic AEs. Our data do not contradict that patients with PID can be advised to be vaccinated against COVID-19, in accordance with applicable national guidelines.

Validation of Generalized Anxiety Disorder 6 (GAD-6)-A Modified Structure of Screening for Anxiety in the Adolescent French Population.

Anxiety disorders remain underdiagnosed and undertreated, especially in child and adolescent populations. This study aimed to examine the construct validity of the Generalized Anxiety Disorder Scale 7 (GAD-7) in a sample of French adolescents by combining the Classical Test Theory (CTT) and the Item Response Theory (IRT) and to assess the invariance of items. A total of 284 adolescents enrolled in school in the Lorraine region were randomly selected to participate in a cross-sectional study. A psychometric evaluation was performed using a combination of CTT and IRT analyses. The study of psychometric properties of GAD-7 revealed poor adequation to the sample population, and engendered the deletion of one item (#7) and the merger of two response modalities (#2 and #3). These modifications generated the new GAD-6 scale, which had a good internal consistency reliability (Cronbach α = 0.85; PSI = 0.83), acceptable goodness-of-fit indices (χ2 = 28.89, df = 9, P = 0.001; RMSEA (90% CI) = 0.088 [0.054; 0.125]; SRMR = 0.063; CFI = 0.857), and an acceptable convergent validity (r = -0.62). Only one item (#5) had a consistent Differential Item Functioning (DIF) by gender. This study evaluated the structure of the GAD-7 scale, which was essentially intended at discriminating adolescent patients with high levels of anxiety, and adapted it to a population of adolescents from the general population. The GAD-6 scale presents better psychometric properties in this general population than the original GAD-7 version.

Lack of freedom predicted poor self-reported health among family caregivers of children with disabilities during the COVID-19 pandemic in Europe.

AIM: We aim to assess the effects of the COVID-19 pandemic on self-reported health and quality of life among family caregivers of children with disabilities across Europe. DESIGN: Cross-sectional study. METHODS: Data from the survey by the Eurocarers and IRCCS-INRCA were used. The data were collected between November 2020 and March 2021 from 16 European countries. Data analysis was done using regression analysis to identify family caregivers' self-reported health and well-being predictors. RESULTS: This study included 289 caregivers. The mean age of children was 12 years. Their family caregiver's mean age was 44, and they were mainly women. Experience of lack of freedom predicted family caregivers' poor self-reported health and quality of life. Children's interrupted health and social services also predicted family caregivers' poor self-reported mental well-being. Longitudinal evidence on the pandemic's effects and a diverse view of family caregivers of children with disabilities are needed to plan effective post-pandemic health services and nursing practice. No Patient or Public Contribution.

Teachers' Emotional Intelligence, Burnout, Work Engagement, and Self-Efficacy during COVID-19 Lockdown.

Teachers' psychological well-being is a crucial aspect that influences learning in a classroom climate. The aim of the study was to investigate teachers' emotional intelligence, burnout, work engagement, and self-efficacy in times of remote teaching during COVID-19 lockdown. A sample of 65 teachers (Mage = 50.49), from early childhood through lower secondary education, were recruited during a period of school closure to answer self-report questionnaires and other measures assessing study variables. Results showed that during the COVID-19 pandemic, teachers reported higher levels of burnout and lower levels of self-esteem due to multiple challenges related to remote teaching and the growing sense of insecurity regarding health safety in the school environment. However, the negative effects of COVID-19 on teachers' self-efficacy, work engagement, and burnout varied according to their own levels of emotional intelligence. These results demonstrate that emotional intelligence may support teachers in facing these challenges.

Hearing healthcare utilisation among older adults with self-reported hearing loss during the COVID-19 pandemic in the United States.

OBJECTIVE: To ascertain the prevalence, causes, and risk factors of hearing healthcare delays in older people with self-reported hearing loss in the United States. DESIGN: This cross-sectional study used data from the National Health and Ageing Trends Study (NHATS), a nationally representative survey of Medicare beneficiaries. A supplemental COVID-19 survey was mailed to the participants from June to October 2020. STUDY SAMPLE: By January 2021, 3257 participants had returned completed COVID-19 questionnaires, with the majority having been self-administered between July and August 2020. RESULTS: The participants in the study represented 32.7 million older adults in the US, with 29.1% reporting hearing loss. Among over 12.4 million older adults who put off needed or planned medical care, 19.6% of those with self-reported hearing loss and 24.5% of hearing aid or device users stated they delayed hearing appointments. Approximately 629,911 older adults with hearing devices were impacted by the COVID-19 outbreak for audiological services. The top three reasons were deciding to wait, service cancellation, and fear of going. Education and race/ethnicity were associated with delaying hearing healthcare. CONCLUSIONS: The COVID-19 pandemic impacted hearing healthcare utilisation among older adults with self-reported hearing loss in 2020, with both patient- and provider- initiated delays.

Pattern of self-reported adverse events related to COVID-19 vaccines in Saudi Arabia: A nationwide study.

Background: Vaccination against coronavirus disease 2019 (COVID-19) is the most effective way to end the pandemic. Any development of adverse events (AEs) from various vaccines should be reported. We therefore aimed to explore major and minor AEs among vaccinated individuals in Saudi Arabia. Methods: This is a nationwide report based on the Saudi Arabian Ministry of Health (MOH) registry. It included those who received COVID-19 vaccines from 17th December 2020 to 31st December 2021. The study included spontaneous self-reported adverse effects to COVID-19 vaccines where the study participants used a governmental mobile app (Sehhaty) to report their AEs following vaccination using a checklist option that included a selection of side-effects. The primary outcome was to determine AEs reported within 14 days of vaccination which included injection site itching, pain, reaction, redness, swelling, anxiety, dizziness, fever, headache, hoarseness, itchiness, loss of consciousness, nausea, heartburn, sleep disruption, fatigue, seizures, anaphylaxis, shortness of breath, wheezing, swelling of lips, face, and throat, loss of consciousness, and admissions into the intensive care unit (ICU). Results: The study included a total number of 28,031 individuals who reported 71,480 adverse events (AEs); which were further classified into minor and major adverse events including ICU admissions post vaccination. Of the reported AEs, 38,309 (53. 6%) side-effects were reported following Pfizer-BioNTech, 32,223 (45%) following Oxford-AstraZeneca, and 948 (1.3%) following Moderna. The following reported AEs were statistically significant between the different vaccine types: shortness of breath\difficulty of breathing, dizziness, fever above 39°C, headache, hoarseness, injection site reactions, itchiness, nausea, sleep disruption, fatigue, wheezing, swelling of lips/face and\or throat, and loss of consciousness (p-value < 0.05). Fever and seizure were the only statistically significant AEs amongst the number of vaccine doses received (p-value < 0.05). Ten ICU admissions were reported in the 14 days observation period post-COVID-19 vaccination with the following diagnoses: acute myocardial infarction, pneumonia, atherosclerosis, acute respiratory failure, intracranial hemorrhage, grand mal seizure, Guillain-Barré syndrome, abnormal blood gas levels, and septic shock. Conclusion: This study demonstrated that the most prevalent SARS-CoV-2 vaccine side-effects among adults in Saudi Arabia were mild in nature. This information will help reduce vaccine hesitancy and encourage further mass vaccination to combat the COVID-19 pandemic, especially as booster doses are now available. Further studies are warranted to obtain a better understanding of the association between risk factors and the experiencing of side-effects post vaccination.

Sociobehavioural Factors Associated With Child Oral Health During COVID-19.

OBJECTIVES: The aim of this study was to identify the sociobehavioural factors that influenced children's oral health during the COVID-19 pandemic. METHODS: The online cross-sectional study was conducted in Al Jouf Province in the northern region of Saudi Arabia. A total of 960 parents of children aged 5 to 14 years were invited by multistage stratified random sampling. Descriptive, multinomial, and multiple logistic regression analyses were performed to estimate odds ratios and determine the relationship between independent and dependent variables. P < .05 was considered statistically significant. RESULTS: Of the 960 participants, 693 (72.1%) reported that their child had 1 or more untreated dental decay. The children of uneducated parents were 1.6-fold more likely to have 1 or more untreated dental decay (adjusted odds ratio [AOR], 1.66; 95% CI, 0.74-3.73; P < .001). The children of unemployed parents were 4.3-fold more likely to have a financial burden for a child dental visit (AOR, 4.34; 95% CI, 2.73-6.89; P < .001). Parents from a rural area were 26.3-fold more likely to have spent a lag period of over 2 years since their child's last dental visit (AOR, 26.34; 95% CI, 7.48-92.79; P < .001). Nursery-level children were 5.4-fold more likely to need immediate care (AOR, 5.38; 95% CI, 3.01-9.60; P < .001). CONCLUSIONS: The present study demonstrated a very high prevalence of 1 or more untreated dental decay in our cohort. Children of rural areas, uneducated, unemployed, widow/divorced, low- and middle-income parents and nursery school children were linked to poorly predictive outcomes of child oral health during the pandemic.

Results of the Cologne Corona Surveillance (CoCoS) study - a cross-sectional study: survey data on risk factors of SARS-CoV-2 infection in adults.

BACKGROUND: The personal, environmental, and behavioral risk factors that play an important role in the spread of SARS-CoV-2 are still largely unclear. At the same time, there is limited evidence on the effectiveness of specific countermeasures for SARS-CoV-2. As a first approach to these questions, we use data from the Cologne Corona Surveillance (CoCoS) study, a large cross-sectional study conducted in Cologne, Germany, in June 2021. METHODS: This study was conducted in Cologne, Germany. Six thousand randomly selected Cologne residents who were 18 years of age or older were invited to participate in this study. Participant information was obtained via an online survey. Previous SARS-CoV-2 infections were recorded using self-reports. Sociodemographic and environmental information such as age, sex, living situation were collected. Potential SARS-CoV-2 risk behaviors were captured (workplace situation, adherence to hygiene regulations, and regular use of public transportation). Adherence to hygiene regulations was surveyed by determining the compliance with the 'AHA'-rules (German acronym that stands for keeping a distance of 1.5 m from fellow citizens, hand disinfection, and wearing a face mask). Binary logistic regression analysis was used to identify risk factors for SARS-CoV-2 infection. RESULTS: A sample of 2,433 study participants provided information. Comparison of the sample with the general population showed representativeness for most sociodemographic characteristics with a preference for higher level of education in the study sample. Younger age, as well as living with minor children (under 18 years) in the same household were associated with a higher number of self-reported SARS-CoV-2 infections. Adherence to hygiene regulations was associated with fewer self-reported SARS-CoV-2 infections in adults. Gender, size of living space per person, workplace situation (work from home versus working with contact to colleagues/customers), and regular use of public transportation showed no significant association with self-reported SARS-CoV-2 infections in multivariable analysis. CONCLUSION: The presented results provide initial indications of which sociodemographic and behavioral factors may be associated with SARS-CoV-2 infection. However, the fact that these factors were recorded without exact dates and could have changed accordingly during the pandemic or after infection limits the strength of the results.

Design, Implementation, and Evaluation of Online Bioinformatics and Neuroinformatics Labs

In recent years, online laboratories have become highly integrated into the educational process due to the development of distance learning tools as well as circumstances associated with the Covid-19 pandemic. As part of a master's degree program in bioinformatics and neuroinformatics, in the academic years 2020–2021 and 2021–2022, the mandatory module "Laboratory Education (LE)” included 9 labs which transitioned to online delivery. A questionnaire was administered to all participants examining their self-reported learning as well as their satisfaction with each lab, the educational material associated with each lab, as well as the facilitator in each lab. A total of 73 postgraduate students completed the questionnaire. According to the results, the overall satisfaction from each laboratory ranged from 3.94 to 4.49/5.00. Furthermore, there is a variety of values in self-reported learning ranging from 23 to 50/50. Finally, although 7 out of 10 students indicated they are satisfied with the distance structure of LE, 8 out of 10 say they prefer LE to be carried out with a physical presence in the labs. © 2023,International journal of online and biomedical engineering.

Immigrant Integration in Europe. A Subjective Well-Being Perspective. Angela Paparusso (2021).

This book explores immigrant integration in Europe in all its complexity and multidimensional character. The author begins by providing a brief historical background of immigration in Europe in order to understand the evolution of this phenomenon towards something structural. She then goes into the traditional models of immigration in that continent and the immigration policies implemented in the different countries, assessing its effect by making reference to the Migrant Integration Policy Index 2020 affected by the COVID-19 pandemic. What makes this book original, in this sphere, is the introduction of the concept of subjective well-being applied both to immigrants and European host countries. This subject is tackled through surveys which lead to the analysis of self-reported life satisfaction among first generation immigrants in seven European countries. In this respect, Angela Paparusso focuses particularly in Italy where she studies the wellbeing and integration of children with a migrant background In her conclusions, she dwells on policy making which calls for the incorporation of local, national, and international governmental institutions and further proposes novel lines of study.

A review on indoor environmental quality in sports facilities: Indoor air quality and ventilation during a pandemic

Because of COVID-19, the indoor environmental quality (IEQ) in sports facilities has been a concern to environmental health practitioners. To develop an overall understanding of the available guidelines and standards and studies performed on IEQ in sports facilities, an extensive literature study was conducted, with the aim of identifying: (1) indicators that are being used to assess IEQ in different sports facilities;(2) indicators that are potentially interesting to be used to assess indoor air, in particular;(3) gaps in knowledge to determine whether sports facilities are safe, healthy and comfortable for people to stay and perform their activities. The outcome indicates that most current standards and previous investigations on IEQ in sports facilities mainly focused on dose-related indicators (such as ventilation rate), while building-related indicators (such as ventilation regime) and occupant-related indicators (such as IEQ preferences) were rarely considered. Little attention is given to the fact that ventilation systems may play an important role in the air quality of the location, and few investigations have been performed on the transmission of SARS-CoV-2. This study recommends more research into both occupant and building-related indicators as well as cross-modal effects between various IEQ factors for developing future standards on sports facilities.

COVID-19 Pandemic Experiences across the Shelter-Care Continuum in Older Adults

The COVID-19 pandemic's impact on older adults (55+) living at the mid-point of the shelter-care continuum, in seniors housing (SH) and assisted living (AL), remains largely unexplored. This study compares survey responses of SH and AL residents with those of age peers living in private conventional community-based dwellings (CD) in British Columbia, Canada. Despite more SH/AL residents reporting feelings of isolation and changes to social support access, the pandemic appears to have had a greater negative impact on the routines of CD older adults. AL residents were more likely to engage in advance care planning discussions before and since the COVID-19 outbreak. These data are important for improving response to current and future disasters across the shelter-care continuum, particularly in ways to reduce the psychosocial effects of isolation or routine disruption, and strategies to increase advance care planning engagement.

Association Between Smoking and SARS-CoV-2 Infection: Cross-sectional Study of the EPICOVID19 Internet-Based Survey.

BACKGROUND: Several studies have reported a low prevalence of current smoking among hospitalized COVID-19 cases; however, no definitive conclusions can be drawn. OBJECTIVE: We investigated the association of tobacco smoke exposure with nasopharyngeal swab (NPS) test results for SARS-CoV-2 infection and disease severity accounting for possible confounders. METHODS: The nationwide, self-administered, cross-sectional web-based Italian National Epidemiological Survey on COVID-19 (EPICOVID19) was administered to an Italian population of 198,822 adult volunteers who filled in an online questionnaire between April 13 and June 2, 2020. For this study, we analyzed 6857 individuals with known NPS test results. The associations of smoking status and the dose-response relationship with a positive NPS test result and infection severity were calculated as odds ratios (ORs) with 95% CIs by means of logistic and multinomial regression models adjusting for sociodemographic, clinical, and behavioral characteristics. RESULTS: Out of the 6857 individuals (mean age 47.9 years, SD 14.1; 4516/6857, 65.9% female), 63.2% (4334/6857) had never smoked, 21.3% (1463/6857) were former smokers, and 15.5% (1060/6857) were current smokers. Compared to nonsmokers, current smokers were younger, were more educated, were less affected by chronic diseases, reported COVID-19-like symptoms less frequently, were less frequently hospitalized, and less frequently tested positive for COVID-19. In multivariate analysis, current smokers had almost half the odds of a positive NPS test result (OR 0.54, 95% CI 0.45-0.65) compared to nonsmokers. We also found a dose-dependent relationship with tobacco smoke: mild smokers (adjusted OR [aOR] 0.76, 95% CI 0.55-1.05), moderate smokers (aOR 0.56, 95% CI 0.42-0.73), and heavy smokers (aOR 0.38, 95% CI 0.27-0.53). This inverse association also persisted when considering the severity of the infection. Current smokers had a statistically significantly lower probability of having asymptomatic (aOR 0.50, 95% CI 0.27-0.92), mild (aOR 0.65, 95% CI 0.53-0.81), and severe infections (aOR 0.27, 95% CI 0.17-0.42) compared to those who never smoked. CONCLUSIONS: Current smoking was negatively associated with SARS-CoV-2 infection with a dose-dependent relationship. Ad hoc experimental studies are needed to elucidate the mechanisms underlying this association. TRIAL REGISTRATION: ClinicalTrials.gov NCT04471701; https://clinicaltrials.gov/ct2/show/NCT04471701.

Urban park use and self-reported physical, mental, and social health during the COVID-19 pandemic: An on-site survey in Beijing, China.

The COVID-19 pandemic created unprecedented challenges for people's health. Studies have demonstrated the positive impact of urban green spaces, particularly urban parks, on physical and mental health. However, few studies have evaluated social health, which is a component of human health, and more understanding of the relationship between urban parks and human health during the COVID-19 pandemic is required. This study examined the effects of urban parks on people's health using a canonical correlation model. Physical, mental, and social health were the dependent health variables, and five factors related to urban parks were the independent variables. This study investigated 22 urban parks inside the Forth Ring Road in Beijing, China using a questionnaire survey. The results demonstrated a positive association between urban parks and human health during the pandemic. Distance to the parks, park area, and park size were positively correlated with physical, mental, and social health. Furthermore, frequency and duration of visits to urban parks were positively associated with mental health and contact with neighbors. The health effects of urban park use varied with park types and locations' urbanization background. These findings can provide insights for health-oriented urban park planning and construction.

Two Routes to Status, One Route to Health: Trait Dominance and Prestige Differentially Associate with Self-reported Stress and Health in Two US University Populations.

Objective: Social status has been extensively linked to stress and health outcomes. However, two routes by which status can be earned - dominance and prestige - may not uniformly relate to lower stress and better health because of inherent behavioral and stress-exposure differences in these two routes. Methods: In one exploratory and two preregistered studies, participants (total N = 978) self-reported their trait dominance and prestige and self-reported several stress and health outcomes. Results: The meta-effects evident across the three studies indicate that higher trait dominance was associated with worse outcomes - higher stress, poorer physical and mental health, poorer behavioral health, poorer life satisfaction, higher negative affect (range of absolute values of non-zero correlations, |r| = [0.074, 0.315], ps < 0.021) - and higher trait prestige was associated with better outcomes - lower stress, better physical and mental health, better behavioral health, better life satisfaction, higher positive and lower negative mood (|r| = [0.134, 0.478], ps < 0.001). These effects remained evident (with few exceptions) after controlling for socioeconomic status, other status-relevant traits, or self-enhancing motives; associations with behavior relevant to the COVID19 pandemic generally were not robust. Conclusions: This work indicates that evolved traits related to the preferred route by which status is earned likely impact self-reported stress and health outcomes. Future research is necessary to examine physiological and other objective indicators of stress and health in more diverse populations.

Health Impacts of the COVID-19 Lockdown Measure in a Low Socio-Economic Setting: A Cross-Sectional Study on Reunion Island.

In March 2020, the French government implemented nation-wide measures to reduce social contact and slow the progression of the emerging coronavirus responsible for COVID-19, the most significant being a complete home lockdown that lasted 8 weeks. Reunion Island is a French overseas department marked by large social inequalities. We draw the hypothesis that distancing and lockdown measures may have contributed to an increase in the social inequalities in health (SIH) on Reunion Island. The aim of our study was to describe the SIH during lockdown in the Reunionese population. We implemented a cross-sectional telephone survey conducted between 13 May and 22 July 2020, using a retrospective data collection on the lockdown period. A total of 892 adult participants (≥18 years) were recruited in the 114 large Reunionese neighborhoods using the quota method within the national "White Pages" telephone directory. Degraded psychological states, an increase in addictive behaviors, difficulties in accessing food, a decrease in physical activity, delayed medical appointments, violence against women, and health problems in children were driven by the socio-economic characteristics of the population, most often to the disadvantage of social groups exposed to poor living conditions. These results suggest that the COVID-19 lockdown contributed to an increase in SIH.

The COVID-19 lockdown: effects of material conditions and social context on self-reported health during confinement

Lockdown policies implemented to defeat the spread of COVID-19 have been shown to be effective from an epidemiological perspective, but little is known about how they affect wellbeing and individual health perception. Using information from the 2020 Social Survey for Andalusia (a southern region in Spain), this paper examines how lockdown affects self-reported health. Contrary to what might be expected, perceived population health generally improved, but not in every social group, with young people and low-income groups reporting a deterioration. Moreover, perceived health became more difficult to predict in terms of the classic health, socio-demographic, socio-economic and residential determinants, with lockdown-related changes being particularly relevant. Direct contact with COVID-19, economic problems resulting from the lockdown and changes in daily activities became key explanatory factors for perceived health, particularly affecting the mental and emotional state of the population.

Self-reported voice difficulties in educational professionals during COVID-19 in Quebec: a cross-sectional mixed-methods study.

Background: The health measures imposed by COVID-19 on workplaces created adverse communication settings. Our cross-sectional study aimed to document the nature and severity of the vocal difficulties experienced by educational professionals a few weeks after the implementation of health measures in schools and early childhood settings in Quebec, Canada while teaching in class.Methods: To this end, we conducted a self-report survey containing nine close-ended questions and one open-ended question regarding self-reported vocal difficulties and the implementation of health measures. The survey was answered by 194 educational professionals in October 2020.Results: Since the introduction of the health measures, respondents reported often or always: having difficulty making themselves heard (66.5%), needing to strain their voice (68.1%), having throat pain after work (38.1%), and being concerned about their vocal health (25.2%). 35.6% perceived that their voice changed moderately or a lot and 75.3% did not feel equipped to take care of their vocal health. Fisher's exact tests revealed the difficulties overall were more present in women (p < 0.05).Discussion: The qualitative analysis of open-ended question answers shows a circular process at play, where the vocal responses to the COVID-19-induced communication barriers contribute to creating more problematic communication settings, thus increasing the challenges for vocal health. Better equipping the professionals to take care of their vocal health by developing resources in their professional settings to help them face vocal challenges in both every day as well as extreme situations, should be a priority.

Could self-reported symptoms be predictors of RT-PCR positivity in suspected COVID-19 cases? The Libya experience.

Background: COVID-19 has symptoms similar to several other respiratory and non-respiratory diseases, which makes differentiating them a challenging task and could lead to unnecessary use of realtime reverse transcriptase polymerase chain reaction (RT-PCR) resources. Aims: The study aimed to assess self-reported symptoms as predictors for RT-PCR positivity in suspected COVID-19 cases. Methods: This was a cross-sectional study. We retrospectively reviewed the database of COVID-19 care centres in the eastern district of Tripoli, Libya, from May to December 2020. Presenting symptoms and RT-PCR test data were extracted. Results: Of the 4593 subjects, 923 (20.1%) had positive RT-PCR result. Sensitivity for COVID-19 disease diagnosis was very low (≤ 18.2%) for all symptoms, except for myalgia (82.1%). Specificity was high for all symptoms (90.7-99.8%), except for myalgia (11.0%). Loss of taste and smell had the highest positive likelihood ratio (LR) for RT-PCR positivity (LR+ = 3.59, 95% CI: 2.95-4.37). In the multiple logistic regression, three symptoms maintained significant contribution to RT-PCR positivity; these were loss of taste and smell (odds ratio (OR) = 3.90, 95% CI: 3.04-4.99), sore throat (OR = 1.50, 95% CI: 1.02-2.19), and myalgia (OR = 0.65, 95% CI: 0.49-0.85). Other significant predictors were history of contact with a COVID-19 case (OR = 0.50, 95% CI: 0.39-0.62), and being female (OR = 1.33, 95% CI: 1.15-1.55). Conclusion: The findings of this study do not support the use of self-reported symptoms for the confirmation of COVID-19 disease in suspected cases because of their poor diagnostic properties.
