Knowledge, acceptance, motivators and barriers of booster dose of COVID-19 vaccination among dental patients: A cross-sectional study.

Given the lingering threat of COVID infection, questions are being raised if coronavirus disease 2019 (COVID-19) vaccine needs annual or regular boosters to maintain high levels of immunity against both the original virus and variants. This study was designed to evaluate the knowledge, acceptance, motivators and barriers of the booster dose of COVID-19 vaccine among the dental patients of District Lucknow, India. A total of 297 respondents were selected by a convenience sampling method in this cross-sectional study from various dental clinics. An anonymous, self-administered, closed-ended questionnaire was used. Overall 37.7% respondents reported to have taken all 3 doses and 57.9% had taken single/double doses. Correct information about booster doses shows a significant association with the number of doses taken. The majority had information about the availability of the Pfizer booster vaccine (69.0%). About 58% of participants had information about the technology used in booster doses. The hesitancy for booster doses and the development of natural immunity by infection show significant associations with the number of doses taken. Only 18.2% patients had hesitation about the booster dose and most of them 78.8% recommended others to take the booster vaccine as soon as possible. The majority assumed that previous COVID-19 vaccines can help them get immune (21.5%) followed by not much research has been done on the booster vaccines (15.5%) and their chronic diseases warn them against the booster dose administration (12.5%). Nearly 18.2% of respondents had hesitation about booster dose and less than one third of the respondents trusted a government source for information about booster dose of COVID vaccine. Nearly 36 % did not know that the booster dose of COVID vaccine is available at health centers. Dental health professionals and policymakers should implement and support strategies to ensure people are vaccinated for COVID-19 booster doses.

A Novel COVID-19 Diagnostic System Using Biosensor Incorporated Artificial Intelligence Technique.

COVID-19, continually developing and raising increasingly significant issues, has impacted human health and caused countless deaths. It is an infectious disease with a high incidence and mortality rate. The spread of the disease is also a significant threat to human health, especially in the developing world. This study suggests a method called shuffle shepherd optimization-based generalized deep convolutional fuzzy network (SSO-GDCFN) to diagnose the COVID-19 disease state, types, and recovered categories. The results show that the accuracy of the proposed method is as high as 99.99%; similarly, precision is 99.98%; sensitivity/recall is 100%; specificity is 95%; kappa is 0.965%; AUC is 0.88%; and MSE is less than 0.07% as well as 25 s. Moreover, the performance of the suggested method has been confirmed by comparison of the simulation results from the proposed approach with those from several traditional techniques. The experimental findings demonstrate strong performance and high accuracy for categorizing COVID-19 stages with minimal reclassifications over the conventional methods.

Obesity Concerns and the Future of a Nation's Health: A Cross-Sectional Study of Physical Activity and Related Awareness of Doctors-in-The-Making, Staff, and Faculty in a Saudi Arabian Medical College.

Background: Saudi Arabian population has amongst the highest prevalence of obesity globally. Apart from nutritional measures, physical activity is considered a major modifiable risk factor for the prevention of obesity and its consequences. An insight into the physical activity and awareness parameters of healthcare professionals and those in the making can provide an insight into how prepared we are to deal with the epidemic of non-communicable diseases. The aim of this study is to find out about the degree of physical activity undertaken by the medical students, faculty and staff at the College of Medicine, King Khalid University, as well as their awareness regarding physical activity guidelines. Methods: This study surveyed 300 adult participants - medical students, faculty and staff - in the College of Medicine, King Khalid University. An international validated questionnaire was used to assess the physical activity profile of participants as well as BMI parameters. Moreover, awareness and knowledge of the recommended physical activity guidelines for adults were also assessed. Results: The study participants comprised around 83% students, 9% faculty members, and 7% staff members. Around 55% of the participants were male, while the rest were female. More than 65% of participants across all categories reported low levels of physical activity, with only about 4.5% of participants across various age groups reporting high levels of physical activity. There was no significant difference by gender across the group (P value = 0.227). Only 17% of the study participants were knowledgeable of the recommended physical activity guidelines for adults. Conclusion: We found a low level of physical activity as well as inadequate awareness about the physical activity guidelines amongst our study participants. This study reiterates the urgent need for well-researched and well-funded health promoting interventions to promote physical activity, especially in the context of health professions' education.

Students' perception of asynchronous versus synchronous distance learning during COVID-19 pandemic in a medical college, southwestern region of Saudi Arabia.

BACKGROUND: COVID-19 preventive measures required a drastic shift to online teaching-learning in most of countries. Institutions used different combinations of live online lectures (synchronous) requiring students to attend the class in real-time, as well as recorded lectures uploaded by the instructors to be accessed by students as per their own convenience (asynchronous). We undertook this study to assess and compare the perceptions of students regarding their learning experiences in the synchronous versus asynchronous mode of instruction using  their teaching-learning during the compulsory online mode of instruction at the peak of the COVID-19 pandemic. METHODOLOGY: This cross-sectional questionnaire-based study received responses from 122 final-year medical students studying at the College of Medicine, King Khalid University, Abha, Saudi Arabia. An online 5-point Likert scale-based questionnaire was used to collect data regarding experience and perception towards synchronous and asynchronous learning. Statistical analysis was done using Statistical Package for Social Sciences (SPSS) version 21.0. A P-value less than 0.05 was considered significant. RESULT: All the students found both synchronous and asynchronous learning to be equally satisfying, enjoyable and comfortable. No statistically significant difference was found when both the methods were analyzed for enhancement of knowledge. The students opined that asynchronous learning helped them manage their time better whereas synchronous learning encouraged more interaction during the live lectures. CONCLUSION: Overall, the students' perceptions regarding both synchronous and asynchronous online learning were positive. As both methods have their advantages/limitations, a mix of both synchronous and asynchronous methods may be adopted depending upon the content of the topic and the desired learning outcomes.

Perceptions of Neurosurgery among Medical Students and Interns: A National Cross-Sectional Study.

Background: Neurosurgery is considered one of the most admired surgical specializations. Still, as evidenced by observations over the years, it is not amongst the top choices of medical students in Saudi Arabia. This study will help in understanding the perception and attitudes of medical students and interns toward the neurosurgery specialization, which will aid in developing strategies to increase the interest of undergraduates in neurosurgery specialization and bridge the human resource gap in this vital specialty. Objectives: This study aimed to assess perceptions, attitudes, and gender differences of medical students and interns toward neurosurgery. The influence of demographic factors on perceptions of neurosurgery of interns and senior medical students in Saudi Arabia was also investigated. Methodology: We conducted a cross-sectional study on a convenience sample of medical students (clinical years) and interns studying in different colleges of medicine in Saudi Arabia. A total of 1014 responses were included in this study (518 males and 496 females). The questionnaire comprised of two parts: the first part carried general descriptive questions, while the second part had 24-item Likert scale-based questions. Results: Around 40% of medical students and 26% of interns agreed or strongly agreed to the statement 'I would consider a career in neurosurgery. Around 70% of both interns and students agreed or strongly agreed with the statement 'Huge prestige is attached to neurosurgery'. The responses to the statement 'Neurosurgery is a male specialty' was significantly different between genders, as 36.5% of the male respondents agreed or strongly agreed with the statement while just 12.5% of the females responded likewise (p = 0.000). Only 23% of participants reported having completed a rotation in neurosurgery. About 44.7% of respondents were interested in taking an elective rotation in neurosurgery, while the remaining respondents (55.3%) responded with a negative answer. Only 23% of participants had completed an undergraduate rotation in neurosurgery. More males (65.3%) agreed or strongly agreed with the statement 'Work as a neurosurgery specialist can impede family life as compared to females (57.5%), which was highly significant (p = 0.000). More medical students (45.1%) responded in the agreement or strong agreement in response to the statement' Neurosurgery should be a compulsory rotation during internship' as compared to interns (25.8%). Around 65% of the respondents agreed or strongly agreed that teachers/seniors have a great influence on students' specialization choices. Around 67% of the respondents foresaw a purely clinical role for themselves after graduation, while 17% were interested in a clinical-academician role. Conclusions: The study reflected a generally positive attitude towards neurosurgery amongst medical students and interns. Interest in neurosurgery as a specialization can be strengthened by enhancing the exposure of students and interns to the specialty. Teachers and seniors can be useful influencers to motivate students to consider neurosurgery specialization.

Public Attitude Towards COVID-19 Vaccination: Validation of COVID-Vaccination Attitude Scale (C-VAS).

Introduction: The fear of emergence of newer strains of SARS-CoV-2 as well as concerns of waning of protection after doses of COVID-19 vaccine has created a degree of global uncertainty surrounding the pandemic. Some of the emerging strains of SARS-CoV-2 have shown potential for causing serious disease and death, a threat that has been ameliorated by ensuring the vaccine coverage in populations. Still, the vaccine coverage remains unsatisfactory in certain populations. Hence, understanding and working on the factors which affect acceptance of the vaccine amongst the public can be considered a priority for public health as much as ensuring availability of the vaccines. Objective: This research work aims to build and validate a scale to assess the public attitude towards COVID vaccination. The proposed scale has been named as COVID Vaccination Attitude Scale (C-VAS). Materials and Methods: A three-stage process was used to develop the C-VAS which includes (1) item generation (deductive and inductive approach); (2) item-refinement (pre-testing and pilot testing, exploratory factor analysis (EFA); and (3) scale validation (confirmatory factor analysis, CFA). The sample size used for this research was 840. In order to overcome the issue of common method bias, the data was collected in two phases. The sample n1 (411) was used for EFA and the sample n2 (429) was employed for undertaking CFA. Common method bias was assessed to check if variations in responses are caused by the instrument instead of the actual dispositions of the respondents. Items of the scale were taken by reviewing the extant literature about vaccination, from the relevant established theories such as health belief model and by interviewing with domain experts. The content validity of the scale was determined. Results: EFA extracted five factors, labelled as "Perceived Benefits", "Perceived Barriers", "Perceived Severity", "Health Motivation" and "Perceived Risk". To further validate the factor-item structure CFA was performed. Conclusion: The measurement model was assessed by applying CFA to examine the reliability, accuracy and validity of the scale. Development of this scale can help in understanding factors that affect vaccine acceptability behavior. This can be used in promoting COVID vaccine coverage in countries and societies which still have low vaccination rates especially due to lack of acceptance of the vaccine. This scale also has the potential to understand public behavior in relation to similar future outbreaks and the acceptance of the mitigatory vaccines.
