The emergence of the SARS-CoV-2 Omicron variant has raised concerns due to its increased transmissibility and potential implications on clinical characteristics and outcomes in infected individuals. The aims of this report were to study the profile of SARS-CoV-2 infection with omicron variant, investigate the infection outcome, reinfection rates with associated factors, antibody levels, and explore the associations between biochemical markers and disease severity. This prospective cohort study was conducted in Duhok city in the Northern of Iraq. All volunteers with confirmed SARS-CoV-2 RT–PCR and confirmed Omicron infection who were older than 18 years old and agreed to participate were recruited for this study. The study was carried out from January to April 2022. There were 234 cases of confirmed SARS-CoV-2 RT–PCR Omicron infection. The mean age was 48.12±17.3 years, 43.2% were vaccinated, and 40.2% were male. Among the recruited patients, 99.1% recovered and did not need hospitalization. In this study, (38.9%) had a history of previously confirmed COVID-19 infection. Reinfection was significantly higher in females than males (p=0.04; OR= 0.56). It was found that the IgG antibody levels were higher in patients who received Pfizer-BioNTech than in those who received other vaccines (p=0.001). The levels of IgG were also significantly higher in patients with mild infection (p=0.046), whereas the levels of D-dimer were significantly higher in patients with severe cases of the infection compared to those with mild or moderate cases (p=0.001). Additionally, the levels of C-reactive protein (CRP) were observed to be higher in individuals with moderate cases of infection than in mild and severe cases (0.001). Individuals who contracted the Omicron strain generally had positive outcomes. Reinfection with the Omicron variant was relatively high. IgG levels were higher in patients with mild disease, implying that they were associated with decreased disease severity. We found significant associations between D-dimer levels and the severity of the disease. Additional research is required to investigate the long-term effects of Omicron infection.

Background: Medical education is continually evolving particularly through the modern implementation of educational technology. Enhancing interactive learning in the classroom or lecture settings is one of the growing uses of educational technology. The role and potential benefits of such technology may not be as evident in developing educational systems like the one in Iraq. The purpose of this study was to examine the effect and perception of the use of an audience response system (ARS) on interactive medical education in Iraq. A mixed quantitative and qualitative research methodology approach was used to study the effects and users' perceptions (both student and tutor) of the ARS., Method: The study was conducted in an Iraqi medical school in the Head and Neck course during the spring semester for third-year medical students. The course involved fifteen one-hour lectures over fifteen weeks. Users' perceptions were evaluated by survey and focus group discussions (FGD). Descriptive statistics were used for quantitative measures and thematic analysis for the qualitative data. An ARS system was installed and integrated into the course lectures throughout the course period of three months to enhance interactive learning. Three to five interactive questions were used in each lecture. Anonymous participation and answers were maintained. The appropriate discussion was initiated when pertinent depending on students' answers., Result: Most students (77% of survey, 85% of FGD) perceived the use of ARS as impactful on their learning. They found the ARS engaging (70%), motivating (76%), promoting interactions (73%), and augment learning through better understanding and remembering (81%). Through the FGD, students expressed improved focus, enhanced thinking and reflection, and joyful learning. The educator perceived the ARS use as practical, interactive, thinking-stimulator, and reflective of student's understanding. The required technology skills were reasonable; however, it demanded extra non-insignificant time to learn the use., Conclusion: The perception of the ARS in this study was overall positive, providing encouragement for wide application of this technology in medical education in the developing world. Further studies are needed to validate and prioritize ARS usage in medical education in Iraq., (© 2022. The Author(s).)
