ABSTRACT

BackgroundPsoriasis (PsO) and psoriatic arthritis (PsA) can greatly impact quality of life and result in substantial personal and societal costs. Complete and up to date data on the prevalence and incidence of these conditions and whether these change over time and vary by age is important for healthcare service planning so that specialist care and funding can be appropriately allocated.ObjectivesTo determine the prevalence and incidence of PsO and PsA in males and females from 2009-2019 across all age groups in England.MethodsWe used Clinical Practice Research Datalink AURUM, a primary care electronic health record database, including 20% of the English population. The codes used to identify patients with PsO and PsA were selected by rheumatologists and dermatologists and cross-checked with published code lists from other studies to ensure inclusion of all relevant codes. All included patients must have data for at least 1 year before their diagnosis. The annual incidence and point prevalence were calculated from 2009-2019 and stratified by age/sex. The study period ended in 2019 to avoid COVID-19 pandemic affecting results.ResultsThe prevalence of PsO and PsA in males and females increased annually, peaking in 2019 (PsO males 2.41% [95% confidence interval (CI) 2.40, 2.42];PsO females 2.60% [95% CI 2.59-2.61];PsA males 0.20% [95% CI 0.20-0.20];PsA females 0.21% [95% CI 0.21- 0.22]), as illustrated in Table 1. In 2019, the prevalence of PsO and PsA was highest in the over 65 years age group;PsO 4.25% [95% CI 4.22-4.28] and PsA 0.38% [95% CI 0.37-0.38]. The annual incidence (per 100,000 person years) of PsO has gradually decreased in males (from 168 (164-171) in 2009 to 148 (145-151) in 2019) but in females it has been stable with a slight annual decrease (from 180 (177-184) in 2009 to 173 (170-176) in 2019). The annual incidence for PsA has increased in both males and females (13 (12-14) in 2009 and 15 (14-16) in 2019 for males and 12 (11-13) in 2009 and 18 (17-19) in 2019 for females).ConclusionThe increasing prevalence of PsO and PsA highlights the importance of organising healthcare services to meet this need, particularly in the elderly population.ReferencesNIL.Table 1.Prevalence of PsO and PsA from 2009-2019 in EnglandYear20092010201120122013201420152016201720182019Population (n)1073383110910802110318501118036711343299112249341137842211657996119336261223432512420998PsO (n)216841229106239819250667259988268032276804286499295712304568311104PsO prevalence (%, 95%CI)-Male1.98 (1.96-1.99)2.06 (2.05- 2.07)2.13 (2.12-2.14)2.19 (2.18-2.20)2.24 (2.23- 2.25)2.33 (2.32- 2.34)2.37 (2.36- 2.38)2.39 (2.38- 2.40)2.40 (2.39- 2.41)2.40 (2.39- 2.42)2.41 (2.40- 2.42)-Female2.07 (2.05- 2.08)2.14 (2.13- 2.16)2.22 (2.21- 2.23)2.29 (2.28- 2.31)2.35 (2.33- 2.36)2.45 (2.43- 2.46)2.50 (2.49- 2.51)2.53 (2.52- 2.54)2.56 (2.54- 2.57)2.58 (2.56- 2.59)2.60 (2.59- 2.61)PsO incidence (100,000 person years)-Male168 (164-171)158 (155- 162)161 (158-165)153 (150-157)161 (157- 164)156 (153- 159)155 (152- 159)154 (151- 157)153 (150-156)150 (147-153)148 (145-151)-Female180 (177-184)176 (172-179)181 (177-184)171 (167-174)175 (171-178)176 (172-180)179 (176-183)178 (174-181)177 (174-181)174 (170-177)173 (170-176)PsA (n)1444515443164681752218545196182072021994232572451425683PsA prevalence (%, 95%CI)-Male0.14 (0.14- 0.14)0.15 (0.14- 0.15)0.15 (0.15- 0.16)0.16 (0.16- 0.16)0.17 (0.16- 0.17)0.18 (0.17- 0.18)0.18 (0.18- 0.19)0.19 (0.18- 0.19)0.19 (0.19- 0.20)0.20 (0.19- 0.20)0.20 (0.20- 0.20)-Female0.13 (0.13- 0.13)0.14 (0.13- 0.14)0.15 (0.14- 0.15)0.15 (0.15- 0.16)0.16 (0.16- 0.16)0.17 (0.17- 0.18)0.18 (0.18- 0.18)0.19 (0.19- 0.19)0.20 (0.19- 0.20)0.20 (0.20- 0.21)0.21 (0.21- 0.22)PsA incidence (100,000 person years)-Male13 (12- 14)12 (11- 13)13 (12- 14)12 (11- 13)13 (12-14)14 (13- 15)14 (13- 15)14 (13-15)1514-16)14(13- 15)15 (14-16)-Female12 (11- 13)13 (12- 14)13 (12- 14)14 (13-15)14 (13-15)15 (14-16)17 (16- 18)16 (15- 17)17 (16- 18)18 (17-19)18 (17-19)Acknowledgements:NIL.Disclosure of InterestsArani Vivekanantham: None declared, Edward Burn: None dec ared, Marta Pineda-Moncusí: None declared, Sara Khalid Grant/research support from: SK has received research grant funding from the UKRI and Alan Turing Institute outside this work.

ABSTRACT

Medical waste has been excessively generated in various medical facilities due to COVID-19, and its treatment has become an important concern. Previously, an optimized medical waste sterilization and shredding system was developed for hospital scale but due to increased demand, it is necessary to scale such a system for different facilities. Therefore, in this paper, a sensitivity analysis for the design variables of the shredding system has been conducted and a surrogate model is developed for stress estimation. The surrogate model was generated using LHS (Latin hypercube sampling), which can represent the overall information of the design domain with a limited number of samples. The surrogate model was then used to increase the number of samples for sensitivity analysis which helped in reducing the computational time for finite element analysis. The sensitive variables for the shredder system were then estimated using sensitivity analysis. Consequently, an efficient design framework for various capacities of medical waste shredder was suggested using sensitivity analysis and a data-driven surrogate model.

ABSTRACT

Coronavirus or COVID-19 is an infectious disease that has been identified in humans. The symptoms range from mild to extremely severe when a person infected with COVID-19 may suffer from pneumonia. Chest imaging that may include radiography, computed tomography (CT), and ultra-sound can be used for detecting thepresence of the virus. The certain distinctive factors that help differentiate COVID-19 from pneumonia are that COVID-19 affects both lungs as opposed to one and lungs may show a ground-glass appearance and abnormalities in liver et cetera. A drawback anyway about this method is that it requires an expert radiologist and provided the size of this pandemic, and the number of cases greatly outnumbers the radiologists. This paper aims to establish a proposal to a reliable, fully automated diagnosis powered by deep learning for diagnosis of COVID-19 from CT. The approach is divided into three phases. The first phase is to look out for abnormalities in lungs. The second phase is to determine the presence of pneumonia using OpenCV for pointingout the regions of interest. The third is to distinguish COVID-19 from pneumonia proceeding on the guidelines mentioned above, which are both the lungs affected as opposed to one, and using the regions that were obtained using OpenCV, endorsing the potential presence of COVID-19. The model, based on convolutional networks, takes advantage of TensorFlow 2.1 and Keras deep learning libraries since both were later integrated and can be used conjointly for the identification and the OpenCV library for image loading and preprocessing. Tenfold method is used for the division of training and test set, and the evaluation metric is accuracy. The model was trained against a dataset of a thousand images (owing to the lack of x-ray images of patients affected with coronavirus), with images of normal versus abnormal lungs in a ratio of 1:1, and was tested for accuracy using the confusion matrix. It provided an accuracyof 86% in pointing out the abnormalities in lungs. Then, the identification of images with normal pneumonia versus those infected with coronavirus was done with an accuracy of 75%. © 2022 Scrivener Publishing LLC.

ABSTRACT

Recruiting and retaining sufficient participants is one of the biggest challenges researchers face while conducting clinical trials (CTs). This is due to the fact of misconceptions and insufficient knowledge concerning CTs among the public. The present cross-sectional study was conducted from April 2021 to May 2022. We evaluated knowledge and attitude among 480 participants using a pretested Arabic questionnaire. The correlation between knowledge and attitude score was tested through Spearman's correlation test, and the logistic regression test evaluated the associated factors for knowledge and attitude. Of the studied participants, 63.5% were male and belonged to the age group less than 30 years (39.6%). Nearly two-thirds (64.6%) of them had never heard of CT. More than half of the participants had poor knowledge (57.1%) and attitude (73.5%) towards CTs. Participants' knowledge scores were significantly associated with education level (p = 0.031) and previous participation in health-related research (p = 0.007). Attitude scores were significantly related to marital status (p = 0.035) and the presence of chronic diseases (p = 0.008). Furthermore, we found a significant positive correlation between knowledge and attitude scores (p < 0.001, Spearman's rho = 0.329). The present study revealed that most of the study population had poor knowledge and moderate attitudes towards CT. Targeted health education programs at different public places are recommended to improve the public's knowledge of the importance of CT participation. In addition, exploratory and mixed-methods surveys in other regions of KSA is required to recognize the region-specific health education needs.

ABSTRACT

Novel coronavirus (nCoV) namely "SARS-CoV-2" is being found responsible for current PANDEMIC commenced from Wuhan (China) since December 2019 and has been described with epidemiological linkage to China in about 221 countries and territories until now. In this study we have characterized the genetic lineage of SARS-CoV-2 and report the recombination within the genus and subgenus of coronaviruses. Phylogenetic relationship of thirty nine coronaviruses belonging to its four genera and five subgenera was analyzed by using the Neighbor-joining method using MEGA 6.0. Phylogenetic trees of full length genome, various proteins (spike, envelope, membrane and nucleocapsid) nucleotide sequences were constructed separately. Putative recombination was probed via RDP4. Our analysis describes that the "SARS-CoV-2" although shows great similarity to Bat-SARS-CoVs sequences through whole genome (giving sequence similarity 89%), exhibits conflicting grouping with the Bat-SARS-like coronavirus sequences (MG772933 and MG772934). Furthermore, seven recombination events were observed in SARS-CoV-2 (NC_045512) by RDP4. But not a single recombination event fulfills the high level of certainty. Recombination mostly housed in spike protein genes than rest of the genome indicating breakpoint cluster arises beyond the 95% and 99% breakpoint density intervals. Genetic similarity levels observed among "SARS-CoV-2" and Bat-SARS-CoVs advocated that the latter did not exhibit the specific variant that cause outbreak in humans, proposing a suggestion that "SARS-CoV-2" has originated possibly from bats. These genomic features and their probable association with virus characteristics along with virulence in humans require further consideration.

ABSTRACT

PURPOSE: The burden of the coronavirus disease of 2019 (COVID-19) pandemic on the healthcare sector has been overwhelming, leading to drastic changes in access to healthcare for the public. We aimed to establish the impact of implemented government partial and complete lockdown policies on the volume of surgical patient admissions at a tertiary referral center during the pandemic. METHODS: A database was retrospectively created from records of patients admitted to the surgical ward through the emergency department. Three 6-week periods were examined: The complete lockdown period (CLP), which included a ban on the use of cars with the exception of health service providers and essential sector workers; A pre-COVID period (PCP) 1 year earlier (no lockdown); and a partial lockdown period (PLP) that involved a comprehensive curfew and implementing social distancing regulations and wear of personal protective equipment (e.g., masks) in public places. RESULTS: The number of patients admitted to the surgery ward was significantly higher in the PCP cohort compared to the CLP and PLP cohorts (p = 0.009), with a 42.1% and 37% decline in patients' admissions, respectively. Admission rates for patients with biliary pathologies and vascular thrombotic events increased. 30-day mortality rates did not differ significantly between the three periods (p = 0.378). CONCLUSIONS: While COVID-19 lockdown regulations had a significant impact on patient admission rates, surgical outcomes were not affected and the standards of care were maintained. Future protocols should strive to improve access to healthcare to avoid complications caused by delayed diagnosis and treatment.

ABSTRACT

Background: During COVID-19 lockdown periods, several studies reported decreased numbers of myocardial infarction (MI) admissions. The lockdown impact has not yet been determined in developing countries. The aim of this study was to investigate the impact that of the lockdown measures might have had on the mean number of MI hospital admissions in Northern Jordan. Methodology: A single-center study examined consecutive admissions of MI patients during COVID-19 outbreak. Participants' data was abstracted from the medical records of King Abdullah University Hospital between 2018 and 2020. Mean and percentages of monthly admissions were compared by year and by lockdown status (pre-lockdown, lockdown, and post-lockdown time intervals). Results: A total of 1380 participants were admitted with acute MI symptoms: 59.2% of which were STEMI. A decrease in number of MI admissions was observed in 2020, from 43.1 (SD: 8.017) cases per month in 2019 to 40.59 (SD: 10.763) in 2020 (P < 0.0001) while an increase in the numbers during the lockdown was observed. The mean number during the pre-lockdown period was 40.51 (SD: 8.883), the lockdown period was 44.74 (SD: 5.689) and the post-lockdown was 34.66 (SD: 6.026) (P < 0.0001 for all comparisons). Similar patterns were observed when percentages of admissions were used. Conclusion: Upon comparing the lockdown period both to the pre- and post-lockdown periods separately, we found a significant increase in MI admissions during the lockdown period. This suggests that lockdown-related stress may have increased the risk of myocardial infarction.

ABSTRACT

Chinese mandarin fruits are an inexpensive and rich source of vitamin C. They have potential benefits in treating acute respiratory infections and mitigating inflammation in critical patients with COVID-19. In Egypt, citrus is the most important fruit tree but is sensitive to salinity stress, resulting in poor vegetative tree growth and reductions in productivity and fruit quality. Magnetic iron has emerged as a promising approach in the citrus tree industry, since it improves vegetative growth, yield, and fruit quality and alleviates salinity stress in Chinese mandarin trees grown in soils suffering from high salt stress. This research is aimed at studying the influence of adding magnetic iron (as soil treatment) on tree canopy growth, yield, and fruit quality of 'Chinese' mandarin trees. Therefore, the treatments were as follows: 0, 250, 500, and or 750 g of magnetic iron.tree-1. Our results indicated that all applications of magnetic iron significantly improved tree canopy volume, leaf total chlorophyll, relative water content, yield (kg.tree-1), and the fruit physical and chemical characteristics of Chinese mandarin. In contrast, leaf Na and Cl content, (%), proline, and total phenolic content were decreased by magnetic iron soil treatments. In respect to vegetative growth, our results indicated that adding magnetic iron at the concentration 750 g.tree-1 caused the best values of tree canopy volume. A similar trend was noticed regarding yield. The increase in yield attained was nearly 19%; the best values were obtained when magnetic iron were used at 750 g.tree-1. In conclusion, the application of magnetic iron can lead to improved fruit production and fruit quality of Chinese mandarin trees grown in salinity stress conditions.

ABSTRACT

BACKGROUND: AU-rich elements (AREs) are located in the 3'UTRs of 22% of human mRNAs, including most transiently expressed inflammatory mediators. By default, AREs mark mRNAs for decay and translational inhibition, but this activity can be temporarily inhibited in case of infection to allow the onset of inflammation. Morbidity and mortality in COVID-19 patients have been associated with dysregulated inflammation, a process that may include aberrant ARE activity. RESULTS: RNA-seq data from available transcriptomic studies were analyzed to investigate a possible differential expression of mRNAs that contain AREs in the context of SARS-CoV-2 infections. ARE-mRNAs turned out to be significantly overrepresented among the upregulated mRNAs after SARS-CoV-2 infection (up to 42%). In contrast, ARE-mRNAs were underrepresented (16%) in the downregulated group. Consequently, at a global scale, ARE-mRNAs are significantly more upregulated after SARS-CoV-2 infection compared to non-ARE mRNAs. This observation was apparent in lung cell line models such as A549 and Calu-3 and with infections with other respiratory viruses and cell lines. Most importantly, at the clinical level, the elevated ARE-mRNA response appeared strongest in blood cells of COVID-19 patients with mild disease. It diminished with disease severity and was least apparent in patients in need of intubation and respiratory-related death. Gene function and clustering analysis suggest that the ARE-response is rather global and the upregulated ARE-mRNAs in patients with mild disease do not particularly cluster in specific functional groups. CONCLUSIONS: Compared to the rest of the transcriptome, ARE-containing mRNAs are preferentially upregulated in response to viral infections at a global level. In the context of COVID-19, they are most upregulated in mild disease. Due to their large number, their levels measured by RNA-seq may provide a reliable indication of COVID-19 severity.

ABSTRACT

SESSION TITLE: COVID-Related Critical Care Cases SESSION TYPE: Case Reports PRESENTED ON: 10/19/2022 11:15 am - 12:15 pm INTRODUCTION: We present a case of diffuse alveolar hemorrhage (DAH) secondary to Immune Thrombocytopenia (ITP) temporally related to SARS-CoV-2 (CoV) vaccine. CASE PRESENTATION: An 80-year-old female presented with dyspnea, hemoptysis, diffuse petechiae, and ecchymosis;no focal neurological deficits or hepatosplenomegaly. She had no history of bleeding or autoimmune disorders;no recent respiratory or gastrointestinal infections;but received Moderna CoV vaccine 4 weeks prior to presentation. Chest X-ray (CXR) and CTA of chest demonstrated multifocal bilateral patchy airspace opacities. Initial platelet was 1 x 109/L with normal morphology of platelet and WBC, and no schistocytes. Coagulation panel, LDH, haptoglobin, and bilirubin were all normal. CoV NAAT was negative. Dexamethasone and IVIG for high suspicion of ITP was initiated. Supportive care including platelet transfusion and oxygen via nasal cannula was maintained. Platelets were severely consumed in spite of treatment with platelets undetectable at nadir and rapid decrease of hemoglobin, approximately 6 g/dL, within 24 hours of admission. IgM and IgG plasma platelet autoantibodies returned positive, confirming ITP diagnosis. Additional workup was unremarkable for infections, rheumatologic disorders, and malignancy. Respiratory state rapidly declined with worsening hemoptysis and significant increase of bilateral airspace opacities on repeat CXR, indicative of DAH. Lung protective mechanical ventilation protocol was initiated on day 2 with medically induced deep sedation and paralysis to minimize hemorrhage exacerbation. Rituximab, romiplostim, and nebulized tranexamic acid were added for severe and refractory ITP, which eventually slowed platelet consumption, reduced pulmonary hemorrhage, and stabilized hemoglobin. Platelets recovered above 30 x 109/L on day 9, and subsequent bronchoscopy showed persistent blood on bronchoalveolar lavage. She was successfully extubated after prolonged 14-day intubation. Platelet normalized before discharge. DISCUSSION: Incidence of ITP related to CoV vaccine is approximately 0.8-0.9 case per million vaccinated. Most cases present with superficial bleeding and respond to first-line agents with rapid recovery. GI bleeding and intracranial hemorrhage, but not DAH, have been reported in several cases, requiring third-line agents to promote platelets recovery and achieve hemostasis. We report a case of DAH secondary to ITP following CoV vaccine. Temporal relationship and severe presentation are consistent with other reports of ITP with life-threatening internal bleeding probably secondary to CoV vaccine. CONCLUSIONS: When DAH is suspected, rapid escalation of treatment to include third-line agents is desired. If intubated, lung protective ventilation with paralysis is preferred to minimize further lung injury due to DAH. Reference #1: Lee EJ, Cines DB, Gernsheimer T, et al.

ABSTRACT

The purpose of this study is to determine how learners feel about distance learning as a substitute for face-to-face learning. A nationwide survey of over 11,000 students was conducted during the covid-19 outbreak to evaluate how students in grades 8-12 responded to and viewed full-time e-learning practices. Two-thirds of students had negative attitudes toward e-learning, according to the findings of the survey in the five selected issues of effectiveness, ease of use, interactivity, motivation, and academic assessment of the e-learning platform. Regardless of the students' age, gender, grade, branch, or technology used, they all had a negative opinion regarding e-learning. In addition to technological issues, the majority of students cited psychological and social factors as reasons for their negative attitudes toward e-learning, such as a lack of readiness and ability to adapt to a new style of education, ineffectiveness of the means and methods used, and poor communication with teachers and other classmate learners. On the practical side, the study's findings point to the necessity to adapt the teaching style via the electronic platform to be more acceptable to students, particularly in terms of engagement and providing a stimulating learning environment.

ABSTRACT

Objective: NA Background: Progressive multifocal leukoencephalopathy, (PML) a demyelinating disease of the brain, caused by the John Cunningham (JC Virus) is usually seen in patients who are immunocompromised. Here, we describe a case of an immunocompetent patient diagnosed with PML and a comprehensive literature review. Case Description: A 64-year-old Caucasian male presented with acute worsening of progressive neurological decline with difficulty in vision and reading. The patient was diagnosed with Coronavirus disease 2019 (COVID-19). Following COVID-19 infection he started to have difficulty in maintaining balance, poor attention span and expressive aphasia. Based on history, examination, CSF markers, histopathology, and T2/FLAIR MRI Brain at the time of presentation the patient was diagnosed with PML in a setting of no immunosuppression disorder. Results: In our literature review, it was seen that the average age of symptom presentation was 57.5 with predominance in males. Most of the patients presented with progressive neurological deficits with symptomology ranging from mild confusion, aphasia, anxiety to sensory disturbances with numbness, hemiparesis and hemianopsia. Out of the 21 cases, patients responded to mirtazapine and intravenous pulse methylprednisolone (IVMP). The mortality rate was close to 50% with 11 fatal cases and 10 non-fatal cases. None of the cases had any immunosuppressive conditions or underlying HIV, malignancy, solids organ or stem cell transplants and were not on immunosuppressive medications. Conclusions: Our case and literature review demonstrate the possibility that PML may very rarely occur in patients that are immunocompetent. Furthermore, our review showed that patients responded well to mirtazapine and IVMP. In our case, the patient was treated with Pelfilgrastim with encouraging results and could be explored as a possible treatment option. We also want to highlight that mortality rate was lower in this review and was only compared to mortality in PML associated with immunocompromised status.

ABSTRACT

Objective: To assess the importance of adenosine signaling in cardiovascular disorders (thrombosis, ischemia) and novel corona virus infection. Methodology: A specified web search was done to gather the relevant information using different scientific research forums and databases like WHO database, Pubmed and Google Scholar etc. Results: Adenosine receptors are P1 type of purinergic receptors and belong to G protein-coupled receptors (GPCRs), which is the largest family of integral membrane bound proteins receptors. Adenosine receptors are further classified into four subclasses known as A1, A2A, A2B, and A3. All four subclasses are being mediated by extracellular adenosine and perform a key role in a wide range of physiological functions such as immune system modulation, angiogenesis and sleep regulation. Adenosine receptors are thought to play a significant role in many pathophysiological conditions including cardiovascular disorders such as ischemia and thrombosis and novel corona virus infection making it a key target against these disorders. Conclusion: We suggest that modulation of adenosine receptor activity could increase the regenerative phase in these disorders by increasing the proliferation and differentiation rates of damaged tissue.

ABSTRACT

COVID-19 is an acute respiratory syndrome that affects the host's breathing and respiratory system. The novel disease's first case was reported in 2019 and has created a state of emergency in the whole world and declared a global pandemic within months after the first case. The disease created elements of socioeconomic crisis globally. The emergency has made it imperative for professionals to take the necessary measures to make early diagnoses of the disease. The conventional diagnosis for COVID19 is through Polymerase Chain Reaction (PCR) testing. However, in a lot of rural societies, these tests are not available or take a lot of time to provide results. Hence, we propose a COVID-19 classification system by means of machine learning and transfer learning models. The proposed approach identifies individuals with COVID-19 and distinguishes them from those who are healthy with the help of Deep Visual Embeddings Inceptionv3, MobileNetv3, and EfficientNetB7, were used in this study along with five different pooling schemes to perform deep feature extraction. In addition, the features are normalized using standard scaling, and 4-fold cross-validation is used to validate the performance over multiple versions of the validation data. The best results of 88.86% UAR, 88.27% Specificity, 89.44% Sensitivity, 88.62% Accuracy, 89.06% Precision, and 87.52% F1-score were obtained using ResNet-50 with Average Pooling and Logistic regression with class weight as the classifier.

ABSTRACT

Background: COVID-19 had made more than 197 million infections and 4 million death. Therefore, we need to assess the prevalence of DM among COVID-19 patients and its effect on the outcome. Objectives: We aim to assess the prevalence, risk factors and outcome of diabetes among COVID-19 patients. Methods: This was a prospective, cross-sectional, hospital-based study enrolled 400 COVID-19 patients and was conducted in COVID-19 isolation centres in North Sudan. Results: Males constituted 275 (68.9%) of the study participants, and the majority of participants were aged between 40 and 60 years 150(37.4%). The prevalence of DM was found to be 49.25% in the study participants. Diabetics were significantly more likely to have a respiratory rate higher than 30 (P=0.012), and oxygen saturation less than 93% (P<0.001), to develop shock (P=0.004), to require oxygen therapy (P<0.001), to be intubated (P<0.001), to develop respiratory failure and organ failure (P<0.001), and to have a poorer outcome (P<0.001). New-onset diabetes occurred in 20 (5%) participants and their mortality was higher compared to non-patients with diabetes (P=0.04). The total mortality of participants was 15.8%. Factors associated with poorer outcome were older age (P<0.001), and having type 1 diabetes (P=0.025).Conclusion: The prevalence of diabetes is very high among COVID-19 patients, and is associated with a more severe disease and a poorer outcome. New onset diabetes was associated with poorer outcome compared to non-diabetics.
