Government, Perception, Middle East, Arab countries, COVID-19, Level of satisfaction, Public aspects of medicine, and RA1-1270

Abstract Background Public acceptance of governmental measures are key to controlling the spread of infectious diseases. The COVID-19 pandemic has placed a significant burden on healthcare systems for high-income countries as well as low- and middle-income countries (LMICs). The ability of LMICs to respond to the challenge of the COVID-19 pandemic has been limited and may have affected the impact of governmental strategies to control the spread of COVID-19. This study aimed to evaluate and compare public opinion on the governmental COVID-19 response of high and LMICs in the Middle East and benchmark it to international countries. Methods An online, self-administered questionnaire was distributed among different Middle Eastern Arab countries. Participants’ demographics and level of satisfaction with governmental responses to COVID-19 were analyzed and reported. Scores were benchmarked against 19 international values. Results A total of 7395 responses were included. Bahrain scored highest for satisfaction with the governmental response with 38.29 ± 2.93 on a scale of 40, followed by the Kingdom of Saudi Arabia (37.13 ± 3.27), United Arab Emirates (36.56 ± 3.44), Kuwait (35.74 ± 4.85), Jordan (23.08 ± 6.41), and Lebanon (15.39 ± 5.28). Participants’ country of residence was a significant predictor of the satisfaction score (P

covid-19, medical education, acceptance, vaccine, and Medicine

Background: COVID-19 was declared a public health emergency of global concern by the World Health Organization (WHO) on January 30, 2020. Vaccination is one of the most effective methods for halting the pandemic and preventing complications. Vaccine hesitancy is a possible threat to global public health. Understanding the key determinants that influence the community's preferences and demands for a future vaccine may aid in the development of strategies to improve the global vaccination program. The aim of this study was to assess the beliefs, barriers, and acceptance of COVID-19 vaccination among Taif University students in Saudi Arabia. Materials and Method: This was a descriptive cross-sectional study, based study in Taif University, Saudi Arabia. Data was collected using a designed self-administered questionnaire that was shared as a link through social media. 332 students were considered eligible to participate voluntarily. Data were analyzed using the (SPSS) program version 25. Results: Out of 332 participants, 278 (83.7%) were accepting to take the covid vaccine, while 54 (16.3%) refused. Believes in vaccine safety and effectiveness and trust in the ability of the vaccine to prevent the complication, were all associated with high acceptance rate. Fear about side effects is considered a major factor for vaccination refusal. Conclusion: Most of the participants have the willingness to be vaccinated. The majority of students who agreed to take the vaccine were in the medical field, and that is mostly due to their high knowledge exposure. This indicates the importance of raising the awareness of the non-medical students.

Online Learning, Teaching, Pedagogy of Care, Technology, Holistic Education, Digital Learning, Special aspects of education, and LC8-6691

This article discusses the importance of pedagogy of care designed for online teaching and learning settings. We offer a model for care in online education built on theoretical foundations, including Jerome Bruner’s (1996) work on folk pedagogies. Through the lens of Bruner’s folk pedagogies, there are new possibilities for developing folk pedagogies designed for care in online spaces. Threading this with experiential learning, humanistic psychology, and theory about technologies, we identify tensions within human-technological intersections, including the intersections of agency between human and machine. While such tensions are important to identify, there is also a need to move beyond the tensions and the implied binary between the human and the technological to envision new assemblages and creative possibilities that afford care and allow for student agency. Stemming from this model, we offer practical implications for educators and researchers towards a human-centered pedagogy of care for online learning pointing to technological futures.

Computer applications to medicine. Medical informatics, R858-859.7, Public aspects of medicine, and RA1-1270

Objective: Many studied investigated the manifestations of COVID-19, yet few described the pattern and severity of otolaryngological symptoms. We aim to describe the picture of COVID-19-associated otorhinolaryngological manifestations and recovery to explore individualized treatment, onward referral, and complications prevention. Design: Prospective longitudinal questionnaire-based study. Setting: The online questionnaire was filled 3 times through a remote interview over a period of 1 month from June 2020 to July 2020. Participants: Patients with confirmed COVID-19 by RT-PCR who were clinically stable. Main Outcome Measures: Date of diagnosis, sociodemographic data, and the presence of predictive factors, such as nasal and paranasal disease, anosmia and dysgeusia. Validated tools were used, such as Sino-nasal Outcome Test (SNOT-22), smell test (medical academy screening tool), Voice Handicap Index (VHI), and Reflux Symptoms Index (RSI). Result: The questionnaire was sent to 363 patients and the response rate was 70.80% (n = 257). The mean age was 34.58 years (SD = 11.22) and the rate of male participants was 60.7%. The most common otorhinolaryngological symptoms at the time of enrollment was fever (48.6%), whilst the commonest severe symptom was cough (57%). After 1 month, only 11 participants had persistent severe symptoms, especially sleep and psychological symptoms (73%), and the majority were female (63.6%). All of them had at least 1 comorbidity. There was a significant difference between the mean age of participants with severe symptoms (mean = 27.45, SD = 8.39) and without severe symptoms (mean = 34.90, SD = 2.53, t (255) = 2.17, P = .031). Conclusion: COVID-19 has a wide-ranged spectrum of presentations, with otorhinolaryngological symptoms being the commonest and most serious. Studying these symptoms is vital to advance management options.

Vestibular rehabilitation, Referral, Physical therapy modalities, Evidence-based practice, Vestibular disorders, Balance disorders, and Medicine

Objectives There is compelling scientific evidence about the role of physiotherapists in vestibular rehabilitation. However, patients with vestibular-associated dizziness and balance disturbances are seldom referred to physiotherapists in Saudi Arabia. Therefore, this study aims to achieve insight into perceptions, knowledge, attitudes, and referral practices among Saudi Arabian medical doctors relating to the role of physiotherapists in vestibular rehabilitation. Methods A sample of 381 medical doctors practicing in Saudi Arabia participated in this nationwide cross-sectional study. The sample was obtained from 226 hospitals across 13 provinces of Saudi Arabia by stratified sampling method. The 23-item questionnaire developed by a team of experts was emailed to medical doctors practicing in various hospitals across Saudi Arabia. Results Out of 1,231 medical doctors invited, 381 medical doctors responded, giving a response rate of 30.9%. One hundred ninety-three (50.6%) medical doctors reported managing patients with vestibular rehabilitation. The most preferred specialist for managing patients with vestibular disorders was an Ear Nose Throat (ENT) specialist (n = 173, 89.6%). Related Sample Cochran’s Q test showed statistically significant difference between preferred specialist for managing patients with vestibular disorders (ENT specialists, physiotherapists, nurses, occupational therapists and audiologists) (χ2(4) = 482.476, p = 0.001). Out of 193 medical doctors, 153 (79.2%) reported no role of the physiotherapist in vestibular rehabilitation. One hundred forty-five (75.1%) of medical doctors reported that they were not aware of the role of physiotherapists in vestibular rehabilitation. Only 27 (15.5%) medical doctors reported referring patients with vestibular disorders to physiotherapists. Conclusion The study reports that physiotherapy services are underutilized in vestibular rehabilitation due to limited referral from Saudi Arabian medical doctors. Therefore, there is a need to increase the awareness among Saudi Arabian doctors about the physiotherapist’s role in vestibular rehabilitation.

Foreign bodies, Respiratory tract, Bronchoscopy, Tracheostomy, Case report, Otorhinolaryngology, and RF1-547

Aspiration of foreign body into the airway is a common emergency in pediatric population and has high risk of morbidity and mortality. Clinical presentation of foreign body aspiration varies between children. Some children may present to emergency department with acute life-threatening presentations that require immediate intervention, while others might have long term coarse of symptoms that were misdiagnosed and mistreated for long time. Variation of clinical presentations based on location of dislodged foreign body in the airway tree and size of the aspirated foreign body. Large impacted foreign body creates extra challenge and possible complications during attempt of retrieval via endoscopy alone. We report a case of large aspirated foreign body that had multiple failed attempts of endoscopic removal, and eventually retrieved using combined endoscopic and open approach without tracheostomy. This technique is safe and efficient in cases that failed conventional endoscopy due to large foreign body size.

Medicine (General) and R5-920

Summary: Background: Hearing loss affects over 50% of people in the US across their lifespan and there is a lack of decision modeling frameworks to inform optimal hearing healthcare delivery. Our objective was to develop and validate a microsimulation model of hearing loss across the lifespan in the US. Methods: We collaborated with the Lancet Commission on Hearing Loss to outline model structure, identify input data sources, and calibrate/validate DeciBHAL-US (Decision model of the Burden of Hearing loss Across the Lifespan). We populated the model with literature-based estimates and validated the conceptual model with key informants. We validated key model endpoints to the published literature, including: 1) natural history of sensorineural hearing loss (SNHL), 2) natural history of conductive hearing loss (CHL), and 3) the hearing loss cascade of care. We reported the coefficient of variance root mean square error (CV-RMSE), considering values ≤15% to indicate adequate fit. Findings: For SNHL prevalence, the CV-RMSE for model projected male and female age-specific prevalence compared to sex-adjusted National Health and Nutrition Examination Survey (NHANES) data was 4.9 and 5.7%, respectively. Incorporating literature-based age-related decline in SNHL, we validated mean four-frequency average hearing loss in the better ear (dB) among all persons to longitudinal data (CV-RMSE=11.3%). We validated the age-stratified prevalence of CHL to adjusted NHANES data (CV-RMSE=10.9%). We incorporated age- and severity-stratified time to first hearing aid (HA) use data and HA discontinuation data (adjusted for time-period of use) and validated to NHANES estimates on the prevalence of adult HA use (CV-RMSE=10.3%). Interpretation: Our results indicate adequate model fit to internal and external validation data. Future incorporation of cost and severity-stratified utility data will allow for cost-effectiveness analysis of US hearing healthcare interventions across the lifespan. Further research might expand the modeling framework to international settings. Funding: This study was funded by the National Institute on Deafness and Other Communication Disorders and the National Institute on Aging (3UL1-TR002553–03S3 and F30 DC019846).

arts and design, college students, creativity, meditation, mindfulness, Social sciences (General), and H1-99

Given the applied nature of creativity in the arts and design, it is important to understand the conditions and practices that support it. Most research suggests that ideal conditions for creativity are often mental and emotional – involving relaxed, yet alert and focused, states of mind. This article explores the connection between mindfulness and creativity in the experiences of students in a college of arts and design, through a mindfulness teaching practice to support creative processes. In a “scholarship of teaching and learning” inquiry, we consider how mindfulness practice may affect arts and design learners’ feelings about their own creativity. Students in a large United States university school of arts and design practiced mindfulness meditation for several months, and submitted a written reflection on their experience. We qualitatively analyze this to consider how mindfulness supports creative practices in arts and design learners’ education. Our findings involve three key themes, which are: “Processing anxiety and negative feelings”, “Focusing the mind”, and “Managing the ‘Voice of Judgment’”. These thematic findings reflect how arts and design students perceive the effects of mindfulness on their creative process. We offer implications for teaching practices related to mindfulness meditation practice aimed to support learners’ perceptions of their creativity.

Biomarkers, Breast cancer, Ceramide expression, Molecular subtypes, Saudi Arabia, Therapeutics. Pharmacology, and RM1-950

Background/Introduction: Despite advances in the diagnosis and management of breast cancer (BC), it is still associated with high mortality rates. New biomarkers are being developed for the diagnosis, treatment, and prediction of responses of BC. Ceramide (CER), a bioactive sphingolipid, has emerged recently as a useful diagnostic tool in several types of tumors. In this study, we evaluated CER expression in invasive BC and assessed its relation to the molecular subtypes of BC. Materials and methods: The clinical data and histopathological slides of 50 patients with invasive ductal carcinoma were retrieved and reviewed. The cases were then stained with a mouse monoclonal anti-ceramide antibody. Pearson correlation was used to assess the correlation between CER percentage and intensity and other clinical and pathological variables. Results: CER expression showed a direct relationship with estrogen and progesterone receptors Allred scores. However, it showed an inverse relation with tumor grade, HER2/neu status and Ki-67 index. Conclusions: CER expression is likely to be associated with luminal BC molecular subtypes. However, more research is needed to confirm these results and to explore its relation to the different clinical outcomes, including response to treatment and prognosis.

knowledge production, technology, learner identity, solidarity, social practices, bottom-up pedagogies, producción de conocimiento, tecnología, identidad, solidaridad, prácticas sociales, pedagogías emergentes, producció de coneixement, tecnologia, identitat, solidaritat, pràctiques socials, and pedagogies emergents

This paper identifies trends in the emerging models of knowledge production available in our society. We suggest it is crucial not only to be aware of these emerging models but also to be open to opportunities and possibilities that may still develop. We consider how people may express different levels of solidarity and commitment to these trends and models in their information consumption and distribution processes. We discuss how educators are now engaging in profound pedagogical renewal by expressing deeper levels of solidarity and commitment to knowledge production and educational projects through professional and personal interactions. These interactions are producing pedagogical models that allow both teachers and learners to become knowledgeable while simultaneously breaking away from domain conventions. These bottom-up pedagogies foster creativity, collaboration and the use of new digital tools. They are driven by learner interests and, as such, have the potential to bring the joy back into the learning process. Finally, we argue that emerging models of knowledge construction mediated by ICT provide new cultural landscapes and ecologies of learning that disrupt traditional inscriptions of individual identities and racial-cultural affinities.
En este artículo, se identificarán algunos modelos y tendencias emergentes en la producción de conocimiento. Se hará hincapié especialmente en cómo los individuos implicados en los procesos de consumo y de distribución de la información expresan diferentes niveles de solidaridad y de compromiso, y se sugerirá que es crucial que las personas no solo conozcan estos procesos, sino que también estén abiertas a otros modelos, oportunidades y posibilidades que, dadas las condiciones sociotecnológicas y comunicativas actuales, aún deben desarrollarse. Se abordará con especial interés el ámbito de la educación, puesto que se entiende que los educadores están participando de forma comprometida en una profunda renovación pedagógica a través de proyectos compartidos cimentados en interacciones profesionales y personales facilitadas por las redes. Estas interacciones favorecen la emergencia de modelos pedagógicos que permiten a profesores y a alumnos convertirse en expertos al mismo tiempo que rompen con muchas convenciones epistemológicas clásicas. Estas pedagogías generadas de abajo arriba no solo fomentan la creatividad y la colaboración, y se sustentan en el uso de nuevas herramientas digitales, sino que las promueven e impulsan los intereses del alumnado, y por ello, tienen el potencial suficiente para devolverle la alegría al proceso de aprendizaje. Por último, se argumentará que los modelos emergentes en la construcción del conocimiento a través de las TIC ofrecen nuevos paisajes culturales y ecologías de aprendizaje que trastocan las inscripciones tradicionales de las identidades individuales y las afinidades raciales y culturales.
En aquest article, s’identificaran alguns models i tendències emergents en la producció de coneixement. Es farà èmfasi especialment en com els individus implicats en els processos de consum i de distribució de la informació expressen diferents nivells de solidaritat i de compromís, i se suggerirà que és crucial que les persones no només coneguin aquests processos, sinó que també estiguin obertes a altres models, oportunitats i possibilitats que, donades les condicions sociotecnològiques i comunicatives actuals, encara s’han de desenvolupar. S’abordarà amb especial interès l’àmbit de l’educació, ja que s’entén que els educadors estan participant de forma compromesa en una profunda renovació pedagògica a través de projectes compartits cimentats en interaccions professionals i personals facilitades per les xarxes. Aquestes interaccions afavoreixen l’emergència de models pedagògics que permeten a professors i a alumnes convertir-se en experts al mateix temps que trenquen amb moltes convencions epistemològiques clàssiques. Aquestes pedagogies generades d’avall cap amunt no només fomenten la creativitat i la col·laboració i se sustenten en l’ús de noves eines digitals, sinó que les promouen i impulsen els interessos de l’alumnat, i per això, tenen el potencial suficient per tornar l’alegria al procés d’aprenentatge. Per acabar, s’argumentarà que els models emergents en la construcció del coneixement a través de les TIC ofereixen nous paisatges culturals i ecologies d’aprenentatge que trastoquen les inscripcions tradicionals de les identitats individuals i les afinitats racials i culturals.

citizen science, conservation, evaluation, grizzly bear, government, principles, Veterinary medicine, SF600-1100, Zoology, and QL1-991

Citizen science offers an excellent opportunity to engage the public in scientific data collection, educational opportunities, and applied management. However, the practicalities of developing and implementing citizen science programming are often more complex than considered. Some challenges to effective citizen science include scientists’ skepticism about the ability of public participants to rigorously collect quality data; a lack of clarity on or confidence in the utility of data; scientists’ hesitancy in engaging the public in projects; limited financial commitments; and challenges associated with the temporal and geographic scales of projects. To address these challenges, and provide a foundation upon which practitioners, scientists, and the public can credibly engage in citizen science, the Government of Alberta developed a set of citizen science principles. These principles offer a framework for planning, designing, implementing, and evaluating citizen science projects that extend beyond Alberta. Here, we present a case study using these principles to evaluate GrizzTracker, a citizen science program developed to help inform provincial species-at-risk recovery efforts. While we found that GrizzTracker applied each of the six principles in some way, including successful public engagement, strengthened relationships, and raising public awareness about northwest Alberta’s grizzly bears, we also identified a number of challenges. These included ongoing skepticism from the traditional scientific community about the utility of citizen science and governance challenges related to program leadership, staff capacity, and funding. By using the principles as a guideline, we provide policy recommendations for future citizen science efforts, including considerations for program design, implementation, and evaluation.

cardiac fibrosis, energy metabolism, fibroblast, myofibroblast, glutaminolysis, transcription, Biology (General), and QH301-705.5

Fibrosis is an energy-intensive process requiring the activation of fibroblasts to myofibroblasts, resulting in the increased synthesis of extracellular matrix proteins. Little is known about the transcriptional control of energy metabolism in cardiac fibroblast activation, but glutaminolysis has been implicated in liver and lung fibrosis. Here we explored how pro-fibrotic TGFβ and its effector scleraxis, which drive cardiac fibroblast activation, regulate genes involved in glutaminolysis, particularly the rate-limiting enzyme glutaminase (GLS1). The GLS1 inhibitor CB-839 attenuated TGFβ-induced fibroblast activation. Cardiac fibroblast activation to myofibroblasts by scleraxis overexpression increased glutaminolysis gene expression, including GLS1, while cardiac fibroblasts from scleraxis-null mice showed reduced expression. TGFβ induced GLS1 expression and increased intracellular glutamine and glutamate levels, indicative of increased glutaminolysis, but in scleraxis knockout cells, these measures were attenuated, and the response to TGFβ was lost. The knockdown of scleraxis in activated cardiac fibroblasts reduced GLS1 expression by 75%. Scleraxis transactivated the human GLS1 promoter in luciferase reporter assays, and this effect was dependent on a key scleraxis-binding E-box motif. These results implicate scleraxis-mediated GLS1 expression as a key regulator of glutaminolysis in cardiac fibroblast activation, and blocking scleraxis in this process may provide a means of starving fibroblasts of the energy required for fibrosis.

Human papillomavirus, Female schoolteachers, Unawareness, HPV vaccine, HPV vaccine uptake, HPV transmission routes, Infectious and parasitic diseases, RC109-216, Public aspects of medicine, and RA1-1270

Background: Human papillomavirus (HPV) is the most common viral infection of the reproductive tract. This cross-sectional study among female schoolteachers assessed the prevalence of i) unawareness of HPV infection’s causal role in cervical cancer; ii) unawareness of HPV vaccine availability and iii) examined the sociodemographic variables associated both the outcome variables. Methods: This cross-sectional study was conducted among female schoolteachers employed in public and private sectors schools in Kuwait using a structured questionnaire for data collection. Prevalence of each of the outcome variables was computed. Multivariable logistic regression analyses were used to evaluate independent predictors of two dependent variables. Results: A total 1341 female schoolteachers were enrolled. Of the participants, 60% were unaware of HPV causal role in cervical cancer and 88% were unaware of HPV vaccine availability. Among those who were aware of HPV vaccine availability, 83.8% were unvaccinated. Multivariable logistic regression (MLR) model showed that 20–29 years old participants or those with low family income (< 500 KD/month) were significantly (p < 0.05) more likely to be unaware of HPV causal role in cervical cancer. Moreover, participants with family/ personal history of cervical cancer were significantly (p < 0.05) less likely to be unaware of HPV role in causation of cervical cancer. A separate MLR model revealed that the participants were significantly more likely to be unaware of HPV vaccine availability if they were Kuwaiti nationals or non-Kuwaiti Arabs (p < 0.05), employed in public schools (p = 0.003) or less likely to be unaware if they had personal or family history of cervical cancer (p < 0.001). Conclusion: High prevalences of unawareness of causal role of HPV in cervical cancer and unawareness of HPV vaccine availability were recorded. Targeted education among identified sociodemographic groups with high levels of unawareness is warranted. If undertaken, future studies may evaluate the impact of recommended efforts.

drugs, FDA, oligonucleotides, peptides, antibody-drug conjugate, inclisiran, Medicine, Pharmacy and materia medica, and RS1-441

From the medical, pharmaceutical, and social perspectives, 2021 has been a year dominated by the COVID-19 pandemic. However, despite this global health crisis, the pharmaceutical industry has continued its endeavors, and 2021 could be considered an excellent year in terms of the drugs accepted by the US Food and Drug Administration (FDA). Thus, during this year, the FDA has approved 50 novel drugs, of which 36 are new chemical entities and 14 biologics. It has also authorized 10 TIDES (8 peptides, 2 oligonucleotides), in addition to 2 antibody-drug conjugates (ADCs) whose structures contain peptides. Thus, TIDES have accounted for about 24% of the approvals in the various drug categories. Importantly, this percentage has surpassed the figure in 2020 (10%), thus reflecting the remarkable success of TIDES. In this review, the approved TIDE-based drugs are analyzed on the basis of their chemical structure, medical target, mode of action, administration route, and adverse effects.

epiregulin, leptin receptor, ERK, EGFR, glucose uptake, energy metabolism, Biology (General), and QH301-705.5

The leptin receptor (LepR) acts as a signaling nexus for the regulation of glucose uptake and obesity, among other metabolic responses. The functional role of LepR under leptin-deficient conditions remains unclear. This study reports that epiregulin (EREG) governed glucose uptake in vitro and in vivo in Lepob mice by activating LepR under leptin-deficient conditions. Single and long-term treatment with EREG effectively rescued glucose intolerance in comparative insulin and EREG tolerance tests in Lepob mice. The immunoprecipitation study revealed binding between EREG and LepR in adipose tissue of Lepob mice. EREG/LepR regulated glucose uptake without changes in obesity in Lepob mice via mechanisms, including ERK activation and translocation of GLUT4 to the cell surface. EREG-dependent glucose uptake was abolished in Leprdb mice which supports a key role of LepR in this process. In contrast, inhibition of the canonical epidermal growth factor receptor (EGFR) pathway implicated in other EREG responses, increased glucose uptake. Our data provide a basis for understanding glycemic responses of EREG that are dependent on LepR unlike functions mediated by EGFR, including leptin secretion, thermogenesis, pain, growth, and other responses. The computational analysis identified a conserved amino acid sequence, supporting an evolutionary role of EREG as an alternative LepR ligand.

Children, Intensive care, SARS-CoV-2, Mortality, Infectious and parasitic diseases, RC109-216, Public aspects of medicine, and RA1-1270

Background: Characteristics of critical Severe Acute Respiratory Syndrome-related Coronavirus 2 (SARS-CoV-2) infection in children is not well understood. This study described the clinical characteristics of children admitted to intensive care units (ICU) and explored factors associated with the need for invasive ventilation or mortality. Methods: A multicenter, retrospective, cohort study was conducted over eight medical centers, including all patients younger than 18 years of age and admitted to the ICU due to a direct consequence of coronavirus disease 2019 (COVID-19). Patients who were admitted to the ICU for any alternate reason and tested positive for SARS-CoV-2 by screening test, and patients who were admitted due to multi-inflammatory syndrome in children, were excluded. Demographic, laboratory, imaging, and clinical data were collected. Descriptive statistics were used to compare survivors and non-survivors. Fine and Gray’s hazard model was used to estimate the association between clinical variables and ICU death. Results: During the study period, 25 pediatric COVID-19 patients received care in the ICUs. The median age was 2.78 years (IQR 0.21–8.51), and 60% were male. Only three patients were reported to be previously healthy at admission. Nine (36%) patients required invasive mechanical ventilation, including two were on extracorporeal membrane oxygenation. Four (16%) patients died during ICU care. In univariate analysis, the presence of comorbidity (HR 0.0001; 95%CI 0.00001–0.00016), platelets count (HR 0.99; 95% CI 0.98–0.99), elevated procalcitonin (HR 1.05; 95%CI 1.016–1.09), and circulatory compromise (HR 16.34; 95%CI 1.99–134.35), all at the time of ICU admission, were associated with in-ICU mortality. Conclusion: Our findings suggest that children admitted to the ICU with SARS-CoV-2 infection, generally, have a favorable outcome. Low platelets count, elevated procalcitonin, presence of comorbidity, and shock at the time of ICU admission were associated with death. This study may shed more light on the disease dynamics of critical pediatric COVID-19.

age of acquisition, bilingualism, english as a second language, perception of speech in noise, signal-to-noise ratio, snr loss, Otorhinolaryngology, RF1-547, Industrial medicine. Industrial hygiene, and RC963-969

Background: Previous studies have highlighted that bilingual listeners have a deficit in speech perception in their second language compared with monolingual listeners in noisy listening environments. This deficit may give rise to educational and occupational implications for bilingual speakers who are studying or working in non-native language environments in poor acoustic conditions. Objectives: To compare the speech perception performance of monolingual English speakers and English as a second language (ESL) bilinguals within environments with various levels of background noise and to examine whether bilinguals with an early age of second language acquisition would perform better than those with a late age of acquisition. Study sample: Two groups of adult listeners with normal hearing participated: monolingual British English listeners (N = 15) and bilingual Arabic listeners for whom English was their second language and who were proficient in English (N = 15). The quick speech-in-noise (QuickSIN) test was used to assess signal-to-noise ratio (SNR) loss and SNR-50 for both groups. Results: The QuickSIN test results indicated that bilingual Arabic listeners with normal hearing displayed a mild SNR loss comparable to that observed for a person with hearing loss, indicating a higher SNR needed for this population to achieve a comparable level of comprehension to their monolingual English peers. Conclusion: Results highlight the importance of measuring SNR loss to obtain accurate diagnosis and potential rehabilitative information that is not available from audiogram studies.

Polycystic ovary syndrome, Binge eating disorder, Health related quality of life, Depression disorder, Riyadh, Biology (General), and QH301-705.5

Background & objectives: Polycystic ovary syndrome (PCOS) is the most common endocrinal disorder, and the greatest cause of infertility in women. Despite availability of individual data on impact of multiple endocrinal, reproductive and even metabolic factors in PCOS individuals, the data on the co-existence of BED and depression in PCOS patients with its relationship on the quality of life in Saudi Arabian females is not found. Hence this study is aimed to elucidate the implication of PCOS on eating behaviour, induction of depression and general health quality in Saudi Arabian population of Riyadh. Materials and methods: This is a cross-sectional study carried out in multiple health facilities of Riyadh from January to March 2019. The study samples (494) were recruited by convenience sampling and administered validated questionnaire by trained research participants. The data obtained was analysed by binary logistic regression using SPSS-IBM 25. Results: Of the total 494 women participated in the study, 23.48% (116) were PCOS individuals. The odds of developing abnormal health related quality of (HRQ) in patients with PCOS was significantly (P = 0.000, OR = 3.472) high when compared to non-PCOS participants. The odds of showing high binge eating disorder (BED, P = 0.007, OR = 2.856) and depression (P = 0.000, OR = 2.497) scores in PCOS participants were significantly more than patients who were not having PCOS. Out of the three parameters studied, abnormal health related quality of life possessed a higher influence of PCOS compared to depression and abnormal eating behavior. Interpretation & conclusion: In conclusion, the present study shows that women with PCOS are at a significant risk for depressive disorders, disorganized eating behavior and impaired quality of life. Therefore, necessary care and screening is required to minimize the impact of PCOS on already burdened individuals.

Computer applications to medicine. Medical informatics, R858-859.7, Public aspects of medicine, and RA1-1270

Background COVID-19 has affected global communities with multiple neurological complications in addition to other critical medical issues. COVID-19 binds to the host’s angiotensin-converting enzyme 2 (ACE2) receptors, which are expressed in the neurons and glial cells, acting as an entry port to the central nervous system (CNS). ACE2 receptors are abundantly expressed on dopamine neurons, which may worsen the prognosis of motor symptoms in Parkinson’s disease (PD). SARS-CoV-2 may lead to an indirect response via immune-mediated cytokine storms and propagate through the CNS leading to damage. In this systematic review, we aim to provide thorough analyses of associations between COVID-19 and neurological outcomes for patients with PD. Methods Using PRISMA statement 2020, a systematic review was conducted to isolate confirmed COVID-19 patients and analyze the PD-associated neurological outcomes using the following databases: PubMed, Science Direct, Google Scholar, and Cochrane databases. The following keywords were used “COVID19, SARS-CoV-2, Parkinson’s disease, Pandemic, Mortality.” A modified Delphi process was employed. Results Of the 355 studies located during the initial round of screening, 16 were included in the final synthesis. Of PD patients who tested positive for SARS-CoV-2, worsening motor symptoms and other viral-associated symptoms were reported. These symptoms included bradykinesia, tremors, gait disturbances, delirium and dementia, and severe spasms of arms and legs. Encephalopathy was presented in 2 of the included studies. Increased mortality rates were identified for hospitalized patients due to COVID-19 and PD as compared to other patient groups. Conclusion Patients with PD may experience substantial worsening of symptoms due to COVID 19. Given the novelty of neurological-viral associations, clinical studies in the future ought to explore the disease severity and neurological outcomes in COVID-19 positive patients with PD as compared to non-PD patients, in addition to understanding the role of ACE2 in increased vulnerability to contracting the infection and as a treatment modality.
