COVID-19-Related Fear and Mental Distress Among Tunisian Primary, Middle and High School Teachers: Prevalence and Predictive Factors.

This study aimed to determine the prevalence and predictive factors of fear of COVID-19 and serious mental distress among teachers in public schools of Southern Tunisia. This was a cross sectional study among a representative sample of 525 teachers. The level of Fear was assessed using the Fear of COVID-19 Scale (FCV-19S). A high level was defined as an FCV-19S ≥ 22. Kessler 6 (K6) was performed to predict serious mental distress. Serious mental distress was defined as a K6 score ≥ 13. The prevalence rates of high level of fear of COVID-19 and serious mental distress were 32.8% and 63.8%, respectively. Independent factors associated with a high level of fear of COVID-19 were female gender (Adjusted odds ratio (AOR)=1.6 [1.1-2.5]), chronic disease (AOR=1.6 [1.1-2.4]), home-living children (AOR=3.3 [1.4-7.8]), and poor material working conditions (AOR=1.5 [1.2-2.1]). The high level of fear of COVID-19 (AOR=3.1 [1.8-5.1]) was independently associated with serious mental distress. Living in a rural area (AOR=0.4 [0.3-0.8]), previous COVID-19 infection (AOR=0.5 [0.4-0.8]) and going to school on foot (AOR=0.3 [0.2-0.51]) were independently associated with a lower prevalence of serious mental distress.

Adverse effects of personnel protective equipment among first line COVID-19 healthcare professionals: A survey in Southern Tunisia.

BACKGROUND: Health care professionals (HCP) were obliged to wear personal protective equipment (PPE) during pandemic in order to minimize the risk of transmission of the emerging virus. The objective of the study was to estimate the prevalence of adverse effects related to the wear of PPE among HCP and to determinate their predictive factors. METHODS: This was a cross-sectional study including a representative sample of 300 randomized HCP at Hedi Chaker University Hospital Sfax, Tunisia, during the period August-September 2021. Data collection was carried out by an anonymous self-administered questionnaire. RESULTS: PPE related adverse effects were noted among 87 HCP with a prevalence of 57.2%. Multivariate analysis showed that factors independently associated with PPE adverse effects were female gender (Adjusted Odds Ratio (AOR) = 1.8; p = 0.048), chronic diseases (AOR = 0.29; p = 0.001) and previous infection with COVID-19 (AOR = 0.46; p = 0.004). Frequent use of bleach or other disinfection product without protection and use of hot water at work were independently associated with a high risk of adverse effects ((AOR = 2.22; p = 0.003) and (AOR = 2.83; p = 0.005), respectively). Similarly, a duration of use of PPE>4 h per day (AOR = 1.98; p = 0.039), as well as use of visors and/or glasses (AOR = 1.84; p = 0.045) were independently associated with PPE related adverse effects. CONCLUSION: The prevalence of adverse effects related to the wear of PPE was alarmingly high among HCP. Multiple risk factors were highlighted, notably professional aspects. Adequate and repetitive training for caregivers on the correct use of PPE remain essential to manage this problem.

E-safe: Smart Ecg-based Authentication On-wrist Healthcare Wearable System

E-SAFE, an IoT-based multimodal health monitoring system, offers a low-cost wrist-based gadget designed especially for the elderly facing the high risk of falling. This paper introduced an affordable solution to securely monitor the elderly health vitals, particularly in the current Covid-19 pandemic. The suggested system integrates a biometric ECGbased authentication process, allowing users to safely access a mobile health monitoring application in real-time. This on-wrist system is a proof-of-concept realized on the Arduino platform to monitor vital health parameters, namely temperature, ECG (electrocardiogram), oxygen saturation (SPO2), heart rate and falls. The obtained experimental results conducted on human subjects carrying out different daily activities show good ECGbased user identification accuracy of 94% using the SVM model and efficient fall-detection using only an accelerometer.

Prevalence and Factors Affecting Willingness to Accept or Refuse Vaccination against COVID-19 among Healthcare Professionals in Southern Tunisia.

BACKGROUND: The COVID-19 pandemic continues to spread throughout the world causing serious morbidity and mortality. Health care professionals (HCP) are on the front line in the face of this pandemic and are identified as priorities for COVID-19 vaccination. This study aimed to estimate the acceptability rate of the COVID-19 vaccination among HCP and to identify their predisposing factors. Methods: This was a cross-sectional study using an anonymous self-administered questionnaire including a randomized sample of HCP in Southern Tunisia, on March-April 2021. Results: Among 300 participants, the COVID-19 vaccine acceptability rate was 65.3%. Factors independently associated with vaccine acceptability were age groups <30 years [Adjusted Odds Ratio (AOR)=4.36; p = 0.002)], urbanity of residence (AOR = 3.44; p = 0.027), medical professional category (AOR = 2.69; p = 0.023) and caring for coronavirus infected patients (AOR = 2.32; p = 0.047). Belief that COVID-19 vaccination is important to work safely as a health care provider (AOR = 3.26; p = 0.013), should be available for all HCP (AOR = 17.98; p = 0.004) and has been quickly developed before it has been thoroughly vetted and tested for efficacy and safety (AOR = 5.88; p < 0.01) were independently associated with willingness to accept vaccine. Planning to get a COVID-19 vaccine for the next years and recommending it to the family were independent predictive factors of accepting COVID-19 vaccine ((AOR = 6.88; p < 0.001) and (AOR = 25.03; p < 0.001), respectively).Conclusion: The acceptance rate of vaccination against COVID-19 among Tunisian HCP is still low in South Tunisian hospitals. Socio-demographic, cultural and professional factors predisposing to the vaccination willingness were highlighted. Combating the vaccine hesitancy of HCP through enhancing sensibilization campaigns is essential to promote vaccination in general population.

Thromboembolic events in COVID-19 ambulatory patients: An observational study about incidence, and thromboprophylaxis outcomes.

INTRODUCTION: There are no clear data about the incidence and the prophylactic strategies of arterial and venous thromboembolic events (TE) in COVID-19 ambulatory patients. Thus, we conducted this study to analyze thromboembolic complications in this setting and to assess thromboprophylaxis management and outcomes in the real life. PATIENTS AND METHODS: This is an observational study including Covid-19 ambulatory patients. We assessed incidence of venous and arterial TE events as well as thromboprophylaxis outcomes and hemorrhagic complications. We defined high risk thrombo-embolic factor according to the Belgian guidelines which are the only guidelines that described thromboprophylaxis in COVID-19 ambulatory patients. RESULTS: We included 2089 patients with a mean age of 43±16 years. The incidence of 30 days venous and arterial TE complications in our cohort was 1%. Venous thromboembolic complications occurred in 0.8% and arterial thromboembolic complications occurred in 0.3%.We noted at least one high-risk TE factor in 18.5% of patients but thromboprophylaxis was prescribed in 22.5% of the cases, LMWH in 18.1%, and Rivaroxaban in 3.7%. Hemorrhagic events occurred in eight patients (0.3%): five patients showed minor hemorrhagic events and three patients showed major ones (0.14%). CONCLUSIONS: Our study showed that the incidence of thromboembolic complications is very low in COVID-19 ambulatory patients. Paradoxically, there is an over prescription of thrombo-prophylaxis in this population.
