The estimated prevalence of osteoporosis in Bahrain: a multi-centered-based study.

OBJECTIVES: the primary aim of this study was to examine the prevalence and risk factors of low bone mineral density in Bahrain. METHODS: this was a retrospective study, which targeted a cohort of 4822 Bahraini subjects (mean age 59.36 years: 93% females). Demographic data and results of lumbar and femur DEXA scan for the targeted sample, over the period 2016-2018, were retrieved from four hospitals. RESULTS: The prevalence of low BMD was 62.3% (46.4% had osteopenia and 15.9% had osteoporosis). The highest rate of osteopenia was detected at the age group younger than 44 years. However, with increasing age, the rate of osteopenia declined, whereas osteoporosis increased (P < 0.001). Females were found to be at higher risk of developing both osteopenia (45.8%) and osteoporosis (18.1%) compared to males (39% and 12.4%, respectively) (P < 0.001). Postmenopausal women exhibited higher rates of low BMD (42.4% osteopenia, 22.3% osteoporosis) compared to elderly men (30.9% osteopenia, 9% osteoporosis). CONCLUSIONS: We reported high prevalence of osteopenia and osteoporosis in Bahrain. Low BMD was more common in females, especially in postmenopausal women. Highest prevalence of osteopenia happened at young age. Therefore, we advocate screening at younger age than previously recommended.

Comparing Online and Face-to-Face Performance in Scientific Courses: A Retrospective Comparative Gender Study of Year-1 Students.

Purpose: As a result of COVID-19 pandemic, medical education at the Arabian Gulf University was instructed to apply online teaching instead of face-to-face for all phases of teaching at the University. Phase-1 is concerned with basic science courses delivered to year 1 students. We conducted this study to detect if there are any differences in the performance of medical students between online and face-to-face ways of learning. Also, a comparison between male and female performance in scientific courses was carried out in pre and during COVID-19 periods. Methods: The participant were first year students for pre COVID-19 period from 2018 to 2019 and during COVID-19 period from 2020 to 2021. The university used Moodle and Zoom as an online way of teaching. The students' performance in the year 1 (three-semester) -online period of teaching were compared with a three-semester-performance of conventional teaching prior to COVID-19. This is a retrospective study that attempts to shed some light on the efficiency of AGU experience in online learning for year 1 (Phase I) students. This study evaluates the outcome of both, online and face-to-face examinations for scientific courses. Results: The results showed that the mean performance of year one medical students in all basic scientific courses (Phase I) during the coronavirus pandemic was greater than the mean performance before the pandemic with the exception of the Biostatistics course. The results by gender showed that the mean performance of females was better than males across all scientific courses before coronavirus. Also, during the COVID pandemic, the mean performance of females was better than males in all basic science courses. Conclusion: Year -1 students' performance in science courses during the coronavirus period seems better than pre COVID19 era. Females' performance was better than males' in both periods; pre and during COVID -19 periods.

Telemedicine in non-communicable chronic diseases care during the COVID-19 pandemic: exploring patients' perspectives.

Purpose: This study aimed to explore challenges facing patients using Telemedicine consultations in non-communicable chronic disease clinics in primary care settings and to evaluate their satisfaction and willingness to use this service in the future. Methods: This is an analytical cross-sectional study enrolling participants who were randomly selected from representative primary care centers in Bahrain and providing Telemedicine consultations. A semi-structured questionnaire permitted data collection using telephone interviews. Results: A total of 251 individuals participated in the study of whom the majority were Bahraini (90.04%), and the mean age was 54.48 ± 10.78 years. Most of the participants 231 (92.03%) were satisfied with the Telemedicine consultation while only 142 (56.80%) were willing to use this service in the future. The main perceived challenges related to Teleconsultations were the lack of physical examination, inadequate time of TM consultation, fear of medical errors, and lack of privacy. The willingness to use TM consultation in the future was mainly determined by the degree of comfort to tell private information (p < 0.01) and to less extent the ease of the communication tool (p = 0.005) on multivariate analysis. Conclusion: TM consultations could be a good complement to conventional consultation formats in the future. The sustainability of this innovative healthcare delivery tool requires addressing acceptability by users, ease of use, patient-centeredness, and technological advances to ensure privacy.

Super-spreading social events for COVID-19 transmission: evidence from the investigation of six early clusters in Bahrain.

Introduction: This study aimed to characterize six early clusters of COVID-19 and derive key transmission parameters from confirmed cases that were traced between April and June 2020 in Bahrain. Methods: Pairs of "infector-infectee" allowed us to map the clusters and estimate the incubation period serial interval as the secondary attack rate. The chi-squared test, with a p-value computed using the Monte Carlo test, measured associations between categorical variables. Statistical analysis was performed using R software and the "data.tree, tidyverse" libraries. Results: From 9 April to 27 June 2020, we investigated 596 individuals suspected of COVID-19, of whom 127 positive cases were confirmed by PCR and linked in six clusters. The mean age was 30.34 years (S.D. = 17.84 years). The male-to-female ratio was 0.87 (276/318), and most of the contacts were of Bahraini citizenship (511/591 = 86.5%). Exposure occurred within the family in 74.3% (411/553), and 18.9% of clusters' cases were symptomatic (23/122 = 18.9%). Mapped clusters and generations increased after 24 May 2020, corresponding to "Aid El-Fitr." The mean incubation period was 4 days, and the mean serial interval ranged from 3 to 3.31 days. The secondary attack rate was 0.21 (95% C.I.) = [0.17-0.24]. Conclusion: COVID-19 transmission was amplified due to the high number of families mixing during "Aid El Fitr" and "Ramadhan," generating important clusters. Estimated serial intervals and incubation periods support asymptomatic transmission.

Validity and reliability of the WHOQOL-BREF in the measurement of the quality of life of Sickle disease patients in Bahrain.

Background: Limited attention is devoted to the improvement of the quality of life of patients suffering from the negative consequences of Sickle cell disease (SCD). Our study focuses on the evaluation of the performance of the WHOQOL-BREF as a tool to measure the quality of life of SCD Patients in Bahrain. Methods: We conducted a cross-sectional study that enrolled 273 SCD patients selected using a simple random sampling technique from primary health-care centers in Bahrain in 2019. A designed questionnaire including the WHOQOL-BREF was filled by the patients in the health centers. The reliability of the WHOQOL-BREF was assessed by standardized Cronbach's alpha coefficient, and the validity was measured by convergent validity, principal component analysis and confirmatory factor analysis. Results: The WHOQOL-BREF had good internal consistency as Cronbach's alpha coefficient for the overall scale was 0.91. The convergent validity results indicated that the correlation coefficients values for all scale domains are significantly correlated at α < 0.01. Confirmatory factor analysis found that the four-domain structure produced a robust fit to the data. Conclusion: The WHOQOL-BREF tool has high internal consistency and validity in assessing the quality of life of Sickle Disease patients in Bahrain.

Lifestyle and Dietary Patterns during the COVID-19 Lockdown in Bahrain: A Web-Based Cross-Sectional Study.

Lifestyle factors such as dietary habits, perceived weight, sleep, and physical activity worsened during the COVID-19 pandemic. Through this study, we aimed to understand the impact of COVID-19 on these lifestyle factors in Bahrain. A cross-sectional study was conducted among 1005 adult Bahrainis. Data were collected online using a structured and validated questionnaire for the assessment of eating habits, physical activity, and lifestyle during the COVID-19 pandemic. Participants were snowballed through those who agreed to answer the online questionnaire. There was a higher consumption of fast food, and a higher dependence on takeaways during the COVID-19 pandemic. About 63.5% of the participants consumed >4 meals per day, compared to 36.5% before the COVID-19. About 30% reported consumption of sugar sweetened beverages from two to three times a day. Weight loss was predominantly observed in persons exercising 1-3 times a week. The consumption of sugar-sweetened beverages was also high, with about 19% reporting drinking sweet beverages once every day, 10.6% from two to three times a day, and 40.4% from one to four times a week. A higher proportion of the participants reported poor sleep quality during the pandemic (31.2%) compared to before (12.2%), and 39.7% of the participants reported feeling lazy. Screen time use also doubled during the pandemic, with participants spending more than five hours per day on screens for entertainment, which went from 22.4% before to 51.9% during the pandemic. The lifestyle and dietary habits changed drastically for our study participants during the pandemic. The increased reliance on processed fast food instead of healthier options is a challenge to be tackled in any future pandemic situation. Future research needs to focus on strategies to promote healthier lifestyle modifications during situations such as the COVID-19 pandemic.

Perceptions of health care workers on maternal and child health services in Pakistan during COVID-19: A cross-sectional study.

Background: Maternal and child healthcare service delivery in vulnerable and fragile health systems has suffered a tremendous impact owing to the shift in focus to curtail the COVID-19 pandemic. We aimed to evaluate the impact of the COVID-19 pandemic on maternal and child healthcare services to inform policy advice for a more resilient maternal and child healthcare service delivery in Pakistan. Methods: A descriptive cross-sectional study was conducted. A structured and validated questionnaire was transformed into an online version and a link was first sent to about 300 healthcare professionals to achieve a sample size of 203, including medical doctors, nurses, and other paramedical staff working in public sector health facilities of the four provinces of Pakistan. The questionnaire was responded to by 195 participants. The Chi-Square test was used to determine the statistical differences between the categorical variables. Results: Although about two-thirds of the participants reported a moderate adherence to protocols and procedures to prevent COVID-19 in their health facilities, the maternal and child health service delivery-related indicators declined during the pandemic. For instance, 66.8% and 62.4% of the participants, respectively, did not agree that a Neonatal Intensive Care Unit and an Intensive Care Unit to admit sick newborns and women with obstetric complications during the COVID-19 pandemic were available during the COVID-19 pandemic. In addition, 23% and 20% of the participants, respectively, reported that staff availability and the provision of cesarean section were moderate to extremely affected. The association between job designation and the impact of COVID-19 was statistically significant (χ2 p = 0.038). Conclusions: The study suggests that maternal and child healthcare services including C-Section, perinatal care, and inpatient care of newborns in Pakistan may have been moderately affected by the COVID-19 pandemic.

Insomnia and Related Factors During the Delta Wave of the COVID-19 Pandemic in the Kingdom of Bahrain: A Cross-Sectional Study.

Purpose: This study aims to estimate the prevalence of insomnia and related risk factors during the Delta wave of the COVID-19 pandemic in the Kingdom of Bahrain. Methods: An analytical cross-sectional study included 646 individuals from the general population aged 18 years and over, living in the Kingdom of Bahrain during the Delta wave of the pandemic. Data were collected by an anonymous online questionnaire using the snowball-sampling technique between June and August 2021. We used the Insomnia Severity Index (ISI) and the generalized anxiety disorder scale (GAD-7) to measure the level of insomnia and anxiety, respectively. Results: A total of 646 individuals participated in the study. Most of the participants were females (86%). The mean age was 38.7 ± 12.7 years (age range 18-89) and around half of the participants were 35 years or older. Clinical insomnia was reported by 20% [95% CI, 16.9-20.0] of the participants, and 50.1% [95% CI, 46.2-50.1] had subclinical insomnia according to ISI. The proportion of insomnia was significantly higher among females, healthcare workers, participants with lower educational levels, a lower or decreased monthly income during the pandemic, or participants who reported anxiety symptoms (all P < 0.01). Scales of anxiety and insomnia revealed a high correlation (r2 = 0.347, P< 0.01). The logistic regression model confirmed that factors independently associated with insomnia are female gender (OR=1.94, 95% CI, 1.00-3.76, P < 0.050) as well as presence of anxiety (GAD-7 score ≥ 5) [OR=12.98, 95% CI, 5.61-30.00, P < 0.001]. Conclusion: The burden of insomnia was significant among the general population in the Kingdom of Bahrain during the Delta wave of the COVID-19 pandemic despite the low severity of this variant. Mental health programs are a high priority during the pandemic and afterward. Detection of insomnia could be used to treat some mental health problems at an early stage.

Predictive validity of admission criteria in predicting academic performance of medical students: A retrospective cohort study.

Introduction: Admission to medical school is one of the most competitive entry points in higher education. Medical school admissions committees need accurate and precise screening tools to select among well-qualified applicants. This study explores data from a cohort of graduated medical students over 6 years to offer a critical perspective on predictive validity in medical school admissions. Methods: A retrospective cohort study of 160 students was performed to identify the predictive validity of admission criteria for medical students to predict academic performance over 6 years for a cohort of all students enrolled in the medical program during the academic year 2013-2014. Results: The main results indicated that there was a statistically significant positive correlation between the admission criteria and Students' performance in Year 1, Year 4, B.Sc. (Bachelor of Medical Science) exam, and Medical Doctor (MD) exam across the 6 years of the medical program, except for the English Test, which showed that there was no significant correlation with average MD exam scores for students who enrolled directly in Year 1. The results related to students who were admitted to the Foundation Program showed that there was no significant correlation between high school Grade Point Average (HSGPA) and their academic performance in Year 1, Year 4, B.Sc. exam, and MD exam. The overall results related to all study samples indicated that all predictor variables correlate significantly with all outcome variables (academic performance), and the results showed that Science test scores demonstrated 27.7, 15.0, 19.7, and 12.6% of variation in Students' performance in Year 1, Year 4, B.Sc. exam, and MD exam, respectively. Conclusion: Science test scores were found to be more predictive of academic performance compared to other predictors. Not all the admission criteria used for student selection are good indicators of their achievement in the medical program. It is recommended that other valid and reliable admission tools, such as the multiple mini-interviews and the questionnaire for a candidate's suitability to follow a problem-based learning curriculum, should be considered.

Is laterality in breast Cancer still worth studying? Local experience in Bahrain.

BACKGROUND: Laterality in breast cancer means an increased frequency of left-sided breast cancers compared to right-sided breast cancers ranging between 1.05 and 1.26. It was first described in 1935 by Fellenberg, Sweden. The explanation of this phenomenon is not clear, but the association with other factors was found. This study aimed to explore the laterality of breast cancer in Bahrain as a model for Arabian countries. The association of laterality with the clinicopathological characteristics of the tumor was also analyzed to explore any applied clinical value. METHODS: This is a cross-sectional, retrospective review of a particular ethnic population to study laterality of breast cancer versus a number of clinicopathological factors, as well as prognosis. The study analyzed 228 breast cancer patients treated in Arabian Gulf University facilities in Bahrain between 1999 and 2020. Three bilateral breast cancer and two malignant phyllodes patients were excluded. The following variables were analyzed: laterality ratio (Lt/Rt) and the association between laterality and clinicopathological characteristics (age at diagnosis, family history of malignancy, size of the tumor, tumor grade, histological type, hormonal receptors and HER2, axillary lymph node status, tumor stage, five-year survival rate, nulliparity, and multifocality). RESULTS: The laterality ratio (Lt/Rt) was 1.06 and was 0.97 for patients below 50 years of age, and 1.19 for patients 50 years of age and above. Analysis of our data showed a statistically significant association between laterality and tumor stage (p. value =0.025) at presentation, and laterality and family history of malignancy (p. value =0.052). Right-sided breast cancer was associated with a higher positive family history of malignancy and an increased ratio of locally advanced and metastatic disease, and a reduced 5-year survival in relation to size and stage. Left-sided breast cancer was associated with higher early tumor stage. CONCLUSION: This is the first study exploring the issue of breast cancer laterality in a defined Arabian population. The laterality ratio in this study was 1.06, which is consistent with the globally published range (1.05 to 1.26) and is increasing with increasing age. The association between breast cancer laterality, and the hormonal and HER2 is still not widely addressed in the available literature, although other clinicopathological characteristics were extensively analyzed.

Innovations in Medical Education During the COVID-19 Era and Beyond: Medical Students' Perspectives on the Transformation of Real Public Health Visits Into Virtual Format.

Background: At the College of Medicine and Medical Sciences (CMMS), Arabian Gulf University (AGU), Bahrain, the Public Health Program comprises two core components, namely, lectures and field visits (consumer products safety, communicable diseases control, and food safety). Digital transformation has innovated the medical educational activities during the COVID-19 pandemic where the real public health field visits were transformed into a virtual format. This study is aimed to examine the potential effect of converting the real public health field visit programs into a virtual format during the COVID-19 pandemic. Methods: All medical students who have submitted online feedback evaluation forms upon completing the Public Health Program in the academic years 2019-2020 (180 students; before the COVID-19 pandemic) and 2020-2021 (167 students; during the COVID-19 pandemic) were included in the study, a total sample size of 347 responses. Independent samples t-test was employed to compare students' feedback on Public Health Program before and during the COVID-19 pandemic while the Pearson chi-square test was used for categorical data. A p-value of <0.05 was considered statistically significant. Results: The mean score of students' satisfaction from the virtual program during the COVID-19 pandemic toward the consumer products safety and food safety field visits was significantly higher than that for students before the COVID-19 pandemic (the real field visits). However, there was no observed statistically significant difference for the Communicable Diseases Control visit. In addition, no significant differences were detected between the mean responses of male and female students toward all field visits, whether the feedback was provided before or during the COVID-19 pandemic. Conclusion: Transformation of real public health field visits into virtual format is acceptable and applicable during the COVID-19 era and maybe beyond.

Perception of online and face to face microbiology laboratory sessions among medical students and faculty at Arabian Gulf University: a mixed method study.

BACKGROUND: The COVID-19 pandemic has impacted all spheres of society including medical education and healthcare systems. In response to the pandemic, there has been a transition in medical education practice from traditional forms of teaching to online instruction delivery and virtual learning. Effective clinical microbiology education involves a combination of 'hands-on' practical learning and instructional delivery of scientific knowledge. Microbiology practical laboratories are critical learning environments offering 'hands-on' learning experiences that cannot be replicated through online learning. We conducted a mixed-methods study to understand the perception of online and face-to-face microbiology laboratory sessions among the medical students and microbiology faculty at Arabian Gulf University (AGU). METHODS: The study participants were third and fourth-year undergraduate medical students and faculty involved in delivering microbiology labs at AGU. The questionnaire consisted of questions ranging from perceived learning style to attitude towards online delivery of microbiology curriculum. After the questionnaire administration (google form), focus group discussion (FGD) was conducted for students and microbiology faculty separately. RESULTS: Among 168 students, 50.6% preferred face-to-face lab sessions as compared to 30.4% who preferred online labs, and 51.8% considered online labs to be an essential addition to face-to-face labs. Among the faculty, 85.7% preferred the face-to-face mode of teaching. All the faculty (100%) disagreed that all the microbiology labs teaching should be online. 57.2% considered online labs to be an essential addition to traditional face-to-face labs. Both faculty and students hold that a blended mode of instructional delivery is vital and indispensable for the transfer of skills and knowledge for microbiology students. CONCLUSION: The blended mode of delivering microbiology laboratory sessions in medical school is successful and well-received by both students and faculty. Students take the responsibility for furthering their own learning and understanding of concepts. Instructors have also noticed that blending learning strategies also successfully enhances the development of cognitive skills and problem-solving abilities in students. A review of the microbiology lab curriculum is necessary to identify content areas that can be delivered effectively through online, face-to-face lab sessions, or both, supported with appropriate tools and infrastructure.

Safety and Immunogenicity of COVID-19 BBIBP-CorV Vaccine in Children 3-12 Years Old.

BACKGROUND AND OBJECTIVES: In the current COVID-19 pandemic, children below the age of 12 could manifest COVID-19 symptoms and serve as a reservoir for the virus in the community. The present study was conducted to evaluate the reactogenicity, and immunogenicity of BBIBP-CorV, prior to involving this age group in the vaccination program in the kingdom of Bahrain. SUBJECTS AND METHODS: The study included 582 children from 3 to 12 years old of Bahraini and non-Bahraini nationality, all of which contributed to the reactogenicity study. Of those, 401 contributed to the immunogenicity study. All children received 2 doses of BBIBP-CorV inactivated virus 3 weeks apart. To assess reactogenicity, children were followed up for 5 weeks to evaluate any vaccine-related adverse events (AE). To assess immunogenicity, blood was collected on day 0 and day 35 to assess antibody titer against S, N, and neutralizing antibody. RESULTS: Of the 582 participants, (45.4%) were female, (54.61%) were male, with 49% in 9-12 age group. Of the 401 children contributing to the immunogenicity study, 274 (68.3%) had no prior exposure to COVID-19. The overall incidence of AE was 27.7%. No significant difference was found among different age groups. The most frequent AE was local (at the injection site) and occurred in 16% of children, followed by fever in 9.3%. No serious adverse events were reported. The Seroconversion rate was 100% among children with no prior exposure to COVID-19. Children with previous COVID-19 exposure had higher averages of anti-S (2379 U/mL compared to 409.1), anti-N (177.6 U/mL compared to 30.9) and neutralizing antibody (93.7 U/mL compared to 77.1) than children with no prior exposure at day 35. CONCLUSIONS: Two doses of COVID-19 BBIBP-CorV on the subjects aged between 3 to 12 has good safety and tolerance and can induce an effective immune response and neutralizing antibody titer.

Perceptions of Medical Students on Distance Learning During the COVID-19 Pandemic: A Cross-Sectional Study from Bahrain.

Purpose: The COVID-19 pandemic resulted in a sudden shift from face-to-face to distance learning. We explored medical students' views of online learning during this pandemic at the Arabian Gulf University in Bahrain. Methods: This was a cross-sectional study of students in years two, three and four (n= 559) using an electronic questionnaire. Data were collected from April 10 to May 5, 2021. The survey included three domains: behavioral, affective, and cognitive. We also analyzed the association between students' perceptions and certain demographic and institutional factors. Results: The number of respondents was 311 (response rate: 55.6%; 27.7% males, 72.3% females). Participants were generally satisfied with distance learning (54.6%), although they had less motivation (46.3%) and required more effort (32.2%). Most students preferred distance learning for theoretical parts, and face-to-face approach for practical components (73.3%). Participants reported that distance learning, improved interaction with instructors and classmates (45.6% and 48.9%, respectively), small group learning (47.6%), independent learning (75.3%) and problem-solving skills (44.7%). The students were comfortable with online assessment (60.1%), and reported improved achievement in written (42.1%) and practical examinations (46%), but not in professional skills grades (21.6%). There was no association between students' perceptions and gender (p= 0.079), year of study (p= 0.28) or attendance of live or recorded sessions (p= 0.904), but there was a positive association with the availability of WiFi (p< 0.01) and attendance of college-organized activities (p< 0.0001). Conclusion: Distance learning was successfully implemented during the COVID-19 pandemic. Students were generally satisfied with distance learning and online assessment, but they had concerns about the clinical skills learning. After the pandemic is over, theoretical components of the curriculum can be delivered using distance learning, whereas hands on elements should be offered face-to-face. However, those curricular reforms will likely need investing in the information technology infrastructure.

The relationship between attendance and academic performance of undergraduate medical students during surgical clerkship.

BACKGROUND: The current study aimed to evaluate the previously unexplored correlation between undergraduate medical students' attendance during their surgical clerkship and their academic performance. It also aimed to explore any difference in the attendance rate between male and female students and whether this difference, if present, affects the academic performance. METHODS: A retrospective descriptive cross-sectional study has been conducted on 331 undergraduate medical students during their surgical clerkships at the College of Medicine and Medical Sciences (CMMS) at Arabian Gulf University (AGU), Bahrain from September 2018 to June 2020. RESULTS: There was a positive statistically significant correlation between students' attendance during surgical clerkship and academic performance (r = 0.360, P <  0.01). Mean attendance rate was greater in each increasing category of academic performance: 47.95% in the weak category (less than 65%, n = 42), 57.62% in the good performance category (65% to less than 75%, n = 108), 67.82% in the very good performance category (75% to less than 85%, n = 126), 83.16% in the excellent performance category (85% and above, n = 55). The mean attendance rate of male students was 59.76% (SD = 25.73), compared to 66.92% (SD = 24.30) in the female students. T-test indicated that the difference between the mean attendance of the two groups of the students (male, female) was statistically significant (t = 2.483, p <  0.05). On the other hand, the difference between the mean academic performance for the two groups of students, male & female, (t = 0.284, p = 0.777) was not statistically significant. CONCLUSIONS: Our study showed a significant relationship between undergraduate medical students' attendance during their surgical clerkship and their academic performance. Further studies are needed to stratify this correlation according to clinical and theoretical teaching activities. No significant difference was observed in academic performance between female and male students.
