Background: COVID-19 is the largest recorded pandemic in history. It causes several complications such as shock, pneumonia, acute respiratory distress syndrome, and organ failure. The objective was to determine COVID-19 outcomes and risk factors in the intensive care (ICU) setting., Methods: A retrospective review of prospectively collected data was conducted. Adult patients with a positive RT-PCR test for COVID-19 admitted to ICUs of a tertiary care hospital between 2020 and 2022 were included. Patients who had severe complex trauma were excluded. The outcomes examined included ventilation use and duration, length of stay (LOS), and mortality., Results: A total of 964 patients were included. The mean ( ± standard deviation, SD) age was 63.7 ± 16.9 years. The majority of the patients were males (59.0 %) and Saudi (75.7 %). Ventilation use was documented in 443 (57.1 %) patients, with a mean ( ± SD) ventilation duration of 9.7 ± 8.4 days. Death occurred in 361 (37.4 %) patients after a mean ( ± SD) of 33.3 ± 44.5 days from infection. The mean ( ± SD) LOS was 30.6 ± 54.1 days in hospital and 5.2 ± 5.4 days in ICU. Ventilation use was associated with older age, males, longer ICU LOS, mortality, and admission to medical-surgical ICU. Crude mortality use was associated with older age, longer ICU LOS, use of ventilator, shorter ventilation duration, and admission to medical-surgical or respiratory ICUs., Conclusions: COVID-19 patients admitted to adult ICUs are at high risk of death and mechanical ventilation. The crude risks of both outcomes are higher in older age and longer ICU LOS and are very variable by ICU type., Competing Interests: Declaration of Competing Interest This manuscript is an original work and is not under consideration for publication by other journals. Some of this study’s findings have been presented at a conference KSA ID week on 13 December 2022., (Copyright © 2024 King Abdulaziz Medical City. Published by Elsevier Ltd.. All rights reserved.)

This retrospective study compared central line-associated bloodstream infection (CLABSI) rates per 1 000 central line days, and overall mortality before and during the COVID-19 pandemic in adult, paediatric, and neonatal ICU patients at King Abdul-Aziz Medical City-Riyadh who had a central line and were diagnosed with CLABSI according to the National Healthcare Safety Network standard definition. The study spanned between January 2018 and December 2019 (pre-pandemic), and January 2020 and December 2021 (pandemic). SARS-CoV-2 was confirmed by positive RT-PCR testing. The study included 156 CLABSI events and 46 406 central line days; 52 and 22 447 (respectively) in pre-pandemic, and 104 and 23 959 (respectively) during the pandemic. CLABSI rates increased by 2.02 per 1 000 central line days during the pandemic period (from 2.32 to 4.34, p  < 0.001). Likewise, overall mortality rates increased by 0.86 per 1 000 patient days (from 0.93 to 1.79, p  = 0.003). Both CLABSI rates (6.18 vs. 3.7, p  = 0.006) and overall mortality (2.72 vs. 1.47, p  = 0.014) were higher among COVID-19 patients compared to non-COVID-19 patients. The pandemic was associated with a substantial increase in CLABSI-associated morbidity and mortality.

Background: The general human immune responses similarity against different coronaviruses may reflect some degree of cross-immunity, whereby exposure to one coronavirus may confer partial immunity to another. The aim was to determine whether previous MERS-CoV infection was associated with a lower risk of subsequent COVID-19 disease and its related outcomes., Methods: We conducted a retrospective cohort study among all patients screened for MERS-CoV at a tertiary care hospital in Saudi Arabia between 2012 and early 2020. Both MERS-CoV positive and negative patients were followed up from early 2020 to September 2021 for developing COVID-19 infection confirmed by RT-PCR testing., Results: A total of 397 participants followed for an average 15 months during COVID-19 pandemic (4.9 years from MERS-CoV infection). Of the 397 participants, 93 (23.4%) were positive for MERS-CoV at baseline; 61 (65.6%) of the positive cases were symptomatic. Out of 397, 48 (12.1%) participants developed COVID-19 by the end of the follow-up period. Cox regression analysis adjusted for age, gender, and major comorbidity showed a marginally significant lower risk of COVID-19 disease (hazard ratio = 0.533, p = 0.085) and hospital admission (hazard ratio = 0.411, p = 0.061) in patients with positive MERS-CoV. Additionally, the risk of COVID-19 disease was further reduced and became significant in patients with symptomatic MERS-CoV infection (hazard ratio = 0.324, p = 0.034) and hospital admission (hazard ratio = 0.317, p = 0.042)., Conclusions: The current findings may indicate a partial cross-immunity, where patients with symptomatic MERS-CoV have a lower risk of future COVID-19 infection and related hospitalization. The present results may need further examination nationally using immunity markers., (© 2023. The Author(s).)

Background: Active involvement of students in class using technology is associated with effective learning and understanding. This work intended to analyze the impact of interactive teaching on medical students' engagement, learning, performance, understanding and attendance in virtual classes of physiology, pathology, and pharmacology during COVID-19 pandemic., Methods: A descriptive cross-sectional study was carried out at college of medicine at King Saud bin Abdulaziz University for Health Sciences (KSAU-HS) in Riyadh during January-April 2022. Third- and fourth-year medical students filled a self-reported questionnaire that assessed students' engagement, understanding, performance, and attendance during the sessions of three courses within the curriculum. The Chi-square test or Fisher's exact test was used to compare the difference between the survey responses., Results: A total of 184/234 questionnaires were completed and returned, with an overall response rate of 78.6%. Fifty-five percent of the participants were involved at least more than 5 times in polls during the class. Majority (86.9%), of the students agreed on enjoying participation in polls during the class, and 88.9% recommended the utilization of the polls again. Participation in polls improved understanding and performance of 88%, and 63% of students respectively. In addition, 38% were neutral regarding attendance improvement and spending more time for the class. Around 53% students agreed that polls improved their grades., Conclusion: In conclusion, this study showed that there is an impact of using interactive polls in virtual classes in medical students at KSAU-HS. It is recommended to continue using polls in all subjects in on-site sessions. This will be a great preface step toward switching the traditional teaching to the interactive teaching using flipped classroom strategy in the future., (© 2023. The Author(s).)

Background: With the rapid transmission of COVID-19 globally, countries have implemented strict governmental measures and social distancing rules that aimed to minimize the spread of the virus. School closures, quarantine orders, and social isolation, coupled with a surge in family stress and lack of peer interactions, are probable causes of mental health complications and psychological symptoms faced by children. This study aims at comparing the HRQoL of children and adolescents with type 1 diabetes (T1D) and affected by COVID-19 infection (personal or familial) and those who were not affected by COVID-19., Materials and Methods: A random sample was selected from children and adolescents diagnosed with T1D at the six major governmental diabetes centers in Kuwait. To measure HRQoL, parent-proxy and self-reports from the Pediatric Quality of Life Inventory (PedsQL TM ) 3.0 Diabetes Module were used., Results: A sample of 455 children and adolescents with T1D diabetes (44.6% male participants and 41.98% affected by COVID-19 infection) was studied. The total score of the HRQoL self-reports was significantly higher compared with parent-proxy reports (79.06 ± 15.19 vs. 73.79 ± 15.17, p < 0.01). Children reported significantly higher HRQoL scores in the "treatment I" domain and "worry" domain and lower scores in the "diabetes" symptoms domain, compared with their parents' reports ( p < 0.01). In the COVID-19-affected group, a major difference was noticed between the total scores of children and parent-proxy reports (77.04 ± 15.81 vs. 72.80±14.90, p = 0.047). The affected children reported significantly lower scores in "diabetes" symptoms (59.50) ( p < 0.01) and higher scores in the "treatment I" domain (81.43) than their parent-proxy reports (72.05) ( p < 0.01)., Conclusion: This is the first report on the health-related quality of life of children with T1D in Kuwait during the COVID-19 era. Parents' or caregivers' experience of caring for their children was negative, as they worried, and reported poorer HRQoL compared with their children's perceptions. There is a need to empower healthcare professionals to support parents and caregivers of children with chronic diseases such as T1D in promoting self-management, enhancing physical and psychological wellbeing, treatment adherence, and continuous health education during pandemics of any kind., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Al-Abdulrazzaq, Khalifa, Alqaisi, Al-Juailla, Othman, Qabazard and Al-Kandari.)

Background: The higher risk of COVID-19 in health care workers (HCWs) is well-known. However, the risk within HCWs is not fully understood. The objective was to compare the COVID-19 risk in intensive care unit (ICU) vs non-ICU locations., Methods: A prospective surveillance study was conducted among HCWs at a large tertiary care facility in Riyadh between March 1st to November 30th, 2020. HCWs included both clinical (provide direct patient care) and nonclinical positions (do not provide direct patient care)., Results: A total 1,594 HCWs with COVID-19 were included; 103 (6.5%) working in ICU and 1,491 (93.5%) working in non-ICU locations. Compared with non-ICU locations, ICU had more nurses (54.4% vs 22.1%, P < .001) and less support staff (2.9% vs 53.1%, P < .001). COVID-19 infection was similar in ICU and non-ICU locations (9.0% vs 9.8%, P = .374). However, it was significantly higher in ICU nurses (12.3% vs 6.5%, P < .001). Support staff had higher risk than other HCWs, irrespective of ICU working status (15.1% vs 7.2%, P < 0.001). The crude relative risk of COVID-19 in ICU vs non-ICU locations was 0.92, 95% confidence interval ( was 0.76-1.11 (P = .374). However, relative risk adjusted for professional category was significantly increased to 1.23, 95% confidence interval 1.01-1.50 (P = .036)., Conclusions: ICU had a significantly higher risk of COVID-19 infection only after adjusting for the distribution and risk of different professional categories. The latter is probably determined by both exposure level and protection practices. The finding underscores the importance of strict implementation of preventive measures among all HCWs, including those performing nonclinical services., (Copyright © 2022 Association for Professionals in Infection Control and Epidemiology, Inc.

BPA is one of the most common endocrine disruptors that is widely being manufactured daily nationwide. Although scientific evidence supports claims of negative effects of BPA on humans, there is also evidence suggesting that a low level of BPA is safe. However, numerous in vivo trials contraindicate with this claim and there is a high possibility of BPA exposure could lead to obesity. It has been speculated that this does not stop with the exposed subjects only, but may also cause transgenerational effects. Direct disruption of endocrine regulation, neuroimmune and signaling pathways, as well as gut microbiata, has been identified to be interrupted by BPA exposure, leading to overweight or obesity. In these instances, cardiovascular complications are one of the primary notable clinical signs. In regard to this claim, this review paper discusses the role of BPA on obesity in the perspective of endocrine disruptions and possible cardiovascular complications that may arise due to BPA. Thus, the aim of this review is to outline the changes in gut microbiota and neuroimmune or signaling mechanisms involved in obesity in relation to BPA. To identify potentially relevant articles, a depth search was done on the databases Nature, PubMed, Wiley Online Library, and Medline & Ovid from the past 5 years. According to Boolean operator guideline, selected keywords such as (1) BPA OR environmental chemical AND fat OR LDL OR obese AND transgenerational effects or phenocopy (2) Endocrine disruptors OR chemical AND lipodystrophy AND phenocopy (3) Lipid profile OR weight changes AND cardiovascular effect (4) BPA AND neuroimmune OR gene signaling, were used as search terms. Upon screening, 11 articles were finalized to be further reviewed and data extraction tables containing information on (1) the type of animal model (2) duration and dosage of BPA exposure (3) changes in the lipid profile or weight (4) genes, signaling mechanism, or any neuroimmune signal involved, and (5) transgenerational effects were created. In toto, the study indicates there are high chances of BPA exposure affecting lipid profile and gene associated with lipolysis, leading to obesity. Therefore, this scoping review recapitulates the possible effects of BPA that may lead to obesity with the evidence of current in vivo trials. The biomarkers, safety concerns, recommended dosage, and the impact of COVID-19 on BPA are also briefly described.

The success of COVID-19 vaccination depends on individual's vaccine acceptance. There has been misinformation on the media that doubts its effectiveness, safety, and long-term risk. Such controversy could affect the acceptance toward the uptake of the COVID-19 vaccine. The objective of this study was to assess the factors influencing the acceptance and hesitancy toward the COVID-19 vaccine in Saudi Arabia. A cross-sectional study was conducted. An online survey was conducted with four parameters: Demographics, medical history, knowledge and information sources about COVID-19 and vaccine, and hesitancy/acceptance of vaccinations. Bivariate analysis between several survey items and the acceptance of COVID-19 vaccine was conducted using Chi-square test. Logistic regression was used to assess to what degree each variable affects the acceptance and the hesitancy toward the COVID-19 vaccine. Approximately 64% show a desire to accept the vaccine while 18.3% were extremely hesitant to take the vaccine. Non-demographic factors that were associated with the acceptance toward the COVID-19 vaccine were the source of health information about COVID-19 (OR:1.63; 95% CI:1.07-2.47), perception toward whether the vaccine is effective on other variants of the virus (OR:7.24; 95% CI:4.58-11.45), previous uptake of the influenza vaccine (OR:1.62; 95% CI:1.07-2.47), and potential mandatory of vaccination in order to travel internationally (OR:16.52; 95% CI:10.23-26.68). This study provides an insight into factors - other than the sociodemographic - influencing the acceptance of the COVID-19 vaccine in Saudi Arabia. The government should address the COVID-19-related misinformation and rumors to increase acceptance of COVID-19 vaccination.

Malaria is a parasitic infection that may result in an acute, life-threatening illness. It is a major public health problem in the tropical world. The disease is caused by the parasites of the genus Plasmodium and is transmitted by female Anopheles mosquitoes. Saudi Arabia is in the elimination phase of malaria control. Several parts of Saudi Arabia report cases of imported malaria among travelers and visitors. The city of Makkah in Saudi Arabia has a population of about 2.3 million. Moreover, over 6 million religious visitors from different parts of the world visit Makkah annually. During the COVID-19 outbreak, travel restrictions were enforced in Makkah to contain the spread of COVID-19. We compare the total reported cases of malaria in Makkah before, during, and after COVID-19 travel restrictions in this retrospective cross-sectional study. Data on demographics, clinical data, and laboratory parameters were collected from the medical records of the Ministry of Health, Saudi Arabia. The annual malaria incidence rates in Makkah were 29.13/million people (2018), 37.82/million people (2019), 15.65/million people (2020), 12.61/million people (2021), and 48.69/million people (2022). Most of the malaria cases in Makkah were caused by Plasmodium falciparum, followed by P. vivax. Sudan, Nigeria, Yamen, Pakistan, and India are the top five countries contributing to malaria cases in Makkah. Weekly malaria case analyses revealed that COVID-19-related travel restrictions resulted in zero malaria cases in Makkah, indicating the magnitude of the travel-related malaria burden in the city.
