Changing trends in the outpatient dental visits during the COVID – 19 pandemic in a tertiary care hospital

The coronavirus pandemic has caused a global public health crisis with an unprecedented shutdown of major establishments and non-emergency services. Disruptions across the country in dental hospitals led to challenges in addressing patient’s dental complaints. The present study aimed to analyse the difference in the pattern of the Outpatient dental visits during the pandemic period in comparison to that of the pre-pandemic period in a tertiary care hospital. This retrospective study was carried out by retrieving the patient data from the diagnostic register of the Department of Oral Medicine and Radiology for a period of one year. The data that was retrieved from 24th September 2019 to 23rd March 2020 was categorized under the pre-pandemic period and the data from 24th March 2020 to 24th September 2020 was grouped under the pandemic period. Patient data regarding the age, gender and clinical diagnosis was recorded and categorized under three main categories: “Emergency”, “urgent” and “elective”. 7550 patients during pre-pandemic period and 4035 patients during the pandemic period visited the dental hospital during the study period. Under the “emergency dental care” category, during the pre-pandemic period, majority of the cases reported of acute dental pain (71.0%) followed by cellulitis and space infection (20.1%) and maxillofacial trauma (8.7%). During the pandemic period, acute dental pain consisted of all emergency visits (n = 307). The proportion of emergency dental visits during the pandemic were significantly higher than the pre-pandemic period. Elective dental visits were significantly higher during pre-pandemic period in comparison to the pandemic period. (P < 0.001). There was a notable change in the outpatient trend of the dental visits during the COVID-19 pandemic in comparison to the pre-pandemic period. Emergency dental services were utilized at a higher rate during the pandemic period in comparison to the pre-pandemic counterpart.     

Incidence of gynaecological cancer during the COVID-19 pandemic: A population-based study in the Netherlands

ObjectiveTo study the impact of the COVID-19 pandemic and consequent lockdown on the number of diagnoses of gynaecological malignancies in the Netherlands.MethodsWe performed a retrospective cohort study using data from the Netherlands Cancer Registry (NCR) on women of 18 years and older diagnosed with invasive endometrial, ovarian, cervical or vulvar cancer in the period 2017–2021. Analyses were stratified for age, socioeconomical status (SES) and region.ResultsThe incidence rate of gynaecological cancer was 67/100.000 (n = 4832) before (2017–2019) and 68/100.000 (n = 4833) during (2020) the COVID-19 pandemic. Comparing the number of diagnoses of the two periods for the four types of cancer separately showed no significant difference. During the first wave of COVID-19 (March-June 2020), a clear decrease in number of gynaecological cancer diagnoses was visible (20–34 %). Subsequently, large increases in number of diagnoses were visible (11–29 %). No significant differences in incidence were found between different age groups, SES and regions. In 2021 an increase of 5.9 % in number of diagnoses was seen.ConclusionIn the Netherlands, a clear drop in number of diagnoses was visible for all four types of gynaecological cancers during the first wave, with a subsequent increase in number of diagnoses in the second part of 2020 and in 2021. No differences between SES groups were found. This illustrates good organisation of and access to health care in the Netherlands.     

Impact of the COVID-19 pandemic in the early-onset colorectal cancer

The COVID19 pandemic has affected the spectrum of cancer care worldwide. Early onset colorectal cancer (EOCRC) is defined as diagnosis below the age of 50. Patients with EOCRC faced multiple challenges during the COVID19 pandemic and in some institutions it jeopardized cancer diagnosis and care delivery. Our study aims to identify the clinicopathological features and outcomes of patients with EOCRC in our Centre during the first wave of the pandemic in comparison with the same period in 2019 and 2021.Patients with EOCRC visited for the first time at Vall d'Hebron University Hospital in Spain from the 1st March to 31st August of 2019, 2020 and 2021 were included in the analysis. 177 patients with EOCRC were visited for the first time between 2019 and 2021, of which 90 patients met the inclusion criteria (2019: 30 patients, 2020: 29 patients, 2021: 31 patients). Neither differences in frequency nor in stage at diagnosis or at first visit during the given periods were observed. Of note, indication of systemic therapy in the adjuvant or metastatic setting was not altered. Days to treatment initiation and enrollment in clinical trials in this subpopulation was not affected due to the COVID-19 outbreak.     

Whole-population trends in pathology-confirmed cancer incidence in Northern Ireland,Scotland and Wales during the SARS-CoV-2 pandemic: A retrospective observational study

IntroductionThe COVID-19 epidemic interrupted normal cancer diagnosis procedures. Population-based cancer registries report incidence at least 18 months after it happens. Our goal was to make more timely estimates by using pathologically confirmed cancers (PDC) as a proxy for incidence. We compared the 2020 and 2021 PDC with the 2019 pre-pandemic baseline in Scotland, Wales, and Northern Ireland (NI).MethodsNumbers of female breast (ICD-10 C50), lung (C33–34), colorectal (C18–20), gynaecological (C51–58), prostate (C61), head and neck (C00-C14, C30–32), upper gastro-intestinal (C15–16), urological (C64–68), malignant melanoma (C43), and non-melanoma skin (NMSC) (C44) cancers were counted. Multiple pairwise comparisons generated incidence rate ratios (IRR).ResultsData were accessible within 5 months of the pathological diagnosis date. Between 2019 and 2020, the number of pathologically confirmed malignancies (excluding NMSC) decreased by 7315 (14.1 %). Scotland experienced early monthly declines of up to 64 % (colorectal cancers, April 2020 versus April 2019). Wales experienced the greatest overall change in 2020, but Northern Ireland experienced the quickest recovery. The pandemic's effects varied by cancer type, with no significant change in lung cancer diagnoses in Wales in 2020 (IRR 0.97 (95 % CI 0.90–1.05)), followed by an increase in 2021 (IRR 1.11 (1.03–1.20).ConclusionPDC are useful in reporting cancer incidence quicker than cancer registrations. Temporal and geographical differences between participating countries mirrored differences in responses to the COVID-19 pandemic, indicating face validity and the potential for quick cancer diagnosis assessment. To verify their sensitivity and specificity against the gold standard of cancer registrations, however, additional research is required.     

The psychological impact of the covid-19 pandemic on radiotherapy cancer patients

In March 2020, the World Health Organization (WHO) characterized the outbreak of the coronavirus disease 2019 (COVID-19) as a pandemic. The aim of this study was to evaluate the psychological impact of the COVID-19 pandemic on cancer patients undergoing radiotherapy.Were enrolled 210 patients in treatment and in follow-up who had access to the Radiation Oncology Department of the Campus Bio-Medico University Hospital Foundation between April and May 2020. The sample was subjected to structured interview and validated questionnaires. 37% of patients showed significant levels of distress; depressive symptoms were reported by 22.4% of patients and 99% of sample had clinically significant anxiety symptoms. All patients anxiety worsened during the COVID-19 pandemic (p=< 0.001). Patients on active treatment had higher levels of distress (3.5 vs 2.6; p = 0.04) and anxiety (3.5 vs 2.6; p = 0.04). Lung cancer patients appeared to be more afraid of COVID-19 than other patients (24.2 vs 22.2). This study highlights the presence of clinically significant anxiety in 99% of sample. This conclusion reflects the condition of emotional distress present during the pandemic which makes it necessary to treat patients in a multidisciplinary perspective that includes psychological support in the care plan.     

Pediatric dental emergency management and parental treatment preferences during COVID-19 pandemic as compared to 2019

Pediatric dental emergency management were temporarily suspended during the COVID-19 pandemic, which worsened urgent dental needs. This retrospective study investigated the management of pediatric emergencies during COVID-19 lockdown and the trends in parental preferences from March to July in 2019 and 2020. Pediatric dental emergencies managed during pandemic was collated, procedures were categorized (emergency, restorative, preventive, elective) and trends in parental treatment preference was compared from March-July 2019/2020. Bivariate analysis was performed using fisher-exact test and statistical significance was set at 5%. Total 1081 children were treated during COVID-19 lockdown, and 1509 procedures were performed, of which 20.8% were emergency, 42% restorative, 24.4% preventive, 12.6% elective. In 2019, 7462 children were treated; and except for emergency (10.6%), other procedures were comparable to 2020. Extractions (267) predominated in 2020 followed by sealants (195); but in 2019, pulectomy (1268), scaling (1251) were predominant. None of the residents who performed aerosol procedures got infected with COVID-19 during the lockdown. Emergency dental needs among pediatric patients were very high during the COVID-19 pandemic in South India, and there was not much change in the trend in parental treatment preference in 2019 and 2020. Further, aerosol procedures did not increase the risk of COVID-19 during the pandemic provided proper universal precautions were followed.     

Seroprevalence of COVID-19 in Riyadh city during the early increase of COVID-19 infections in Saudi Arabia,June 2020

Severe acute respiratory syndrome coronavirus (SARS-CoV-2) emerged in December 2019 and caused a global pandemic of the Coronavirus Disease 2019 (COVID-19). More than 170 million cases have been reported worldwide with mortality rate of 1–3%. The detection of SARS-CoV-2 by molecular testing is limited to acute infections, therefore serological studies provide a better estimation of the virus spread in a population. This study aims to evaluate the seroprevalence of SARS-CoV-2 in the major city of Riyadh, Saudi Arabia during the sharp increase of the pandemic, in June 2020. Serum samples from non-COVID patients (n = 432), patients visiting hospitals for other complications and confirmed negative for COVID-19, and healthy blood donors (n = 350) were collected and evaluated using an in-house enzyme-linked immunosorbent assay (ELISA). The overall percentage of positive samples was 7.80% in the combined two populations (n = 782). The seroprevalence was lower in the blood donors (6%) than non-COVID-19 patients (9.25%), p = 0.0004. This seroprevalence rate is higher than the documented cases, indicating asymptomatic or mild unreported COVID-19 infections in these two populations. This warrants further national sero-surveys and highlights the importance of real-time serological surveillance during pandemics.     

The influence of the COVID-19 pandemic on spring turkey hunting

The rapid rise of COVID-19 and the governmental response to slow the spread of the pandemic occurred prior to, or during, the opening of the spring wild turkey (Meleagris gallopavo) hunting seasons (Mar to May 2020) in the United States. The response of fish and wildlife agencies to the pandemic varied throughout the United States during the spring turkey season. The Nebraska Game and Parks Commission (NGPC) suspended the sale of non-resident, spring turkey hunting permits on 30 March 2020 in a proactive effort to minimize the spread of COVID-19. In this study, we evaluated the extent that the COVID-19 pandemic affected the spring turkey permit sales and harvest in Nebraska, USA. We combined information from NGPC's electronic licensing system, responses from 2017–2019 spring turkey hunter surveys (pre-pandemic), and responses from the 2020 (during the pandemic) spring turkey hunter survey, which included additional questions about the influence of COVID-19 on respondents' hunting experiences. There was an increase in the number of resident hunters (23%) and resident permits sold (26%) and a decrease in the number of non-resident hunters (−88%) and non-resident permits sold (−89%) in 2020 as compared to the 3 years prior. Further, non-residents, more so than Nebraska residents, claimed that the COVID-19 pandemic affected their spring turkey hunting in their precautions taken, overall satisfaction, pre-season planning for the spring turkey season, and plans made prior to the outbreak. Wildlife agencies should prepare for the potential effects that significant disruptions (like that observed with the COVID-19 pandemic) might have on hunting participation, especially if a significant portion of revenue is derived from non-resident permit sales, and develop plans and policies so that they can react appropriately.     

Epidemiological determinants for the spread of COVID-19 in Riyadh Province of Saudi Arabia

Background and objectiveCoronavirus Disease 2019 (COVID-19) has affected millions of individuals all over the world. In addition to the patients' compelling indications, various sociodemographic characteristics were identified to influence infection complications. The purpose of this study was to assess the impact of the aforementioned parameters on the dissemination of COVID-19 among residents of Saudi Arabia's Riyadh region.Materials and methodsIn the Saudi Arabian province of Riyadh, a cross-sectional retrospective analysis of COVID-19 incidences, recoveries, and case-fatality ratio (CFR) was undertaken. The study was carried out by gathering daily COVID-19 records from the ministry of health's official websites between October 2020 and September 2021. The influencing factors were obtained from the statistical authority. Using the SPSS IBM 25 software, the data was examined. The association between demographic factors as well as the presence of comorbidity on the COVID-19 outcome was determined using Spearman's correlation and regression tests. P < 0.05 was considered to indicate the significance of the results.ResultsThe data from the study indicated that the highest number of COVID-19 cases were recorded in June 2021, and peak recovery was observed in July 2021. The CFR declined progressively from October 2020 to just over 1, even when the cases peaked. A significant (p < 0.05) correlation between diabetes and COVID-19 incidences was observed. The recovery rate had a significant (p < 0.05) association with the literacy rate and those aged 14–49 years old. Presences of co-morbidities such as Dyslipidemia, hypertension, diabetes, asthma, stroke and heart failure have negatively affected the recovery from COVID-19 in the population. The CFR is significantly (p < 0.05) associated with people over 60, hypertensive patients, and asthma patients. Regression analysis suggested that the risk of complications due to COVID-19 infection is more in males, people above 60 years age and those suffering from co-morbidities.ConclusionsThe findings of the study indicate an association between several of the characteristics studied, such as gender, age, and comorbidity, and the spread of infection, recovery, and mortality. To restrict the spread of COVID-19 and prevent its complications, effective measures are required to control the modifiable risk factors.     

Diagnosis and treatment of lung cancer in Denmark during the COVID-19 pandemic

BackgroundWe examined the number of lung cancers diagnosed, the quality of care and the socio-economic and clinical characteristics among patients with lung cancer during the COVID-19 pandemic compared to previous years.MethodsWe included all patients ≥ 18 years old diagnosed with lung cancer from 01 January 2018 to 31 August 2021 as registered in the Danish Lung Cancer Registry. Using a generalised linear model, we estimated prevalence ratios (PR) and 95% confidence intervals (CI) of the associations between the pandemic and socioeconomic and clinical factors, and indicators of quality.ResultsWe included 18,113 patients with lung cancer (82.0% non-small cell lung cancer (NSCLC)), which was similar to the preceding years, although a decline in NSCLC cases occurred during the first lockdown period in 2020. No difference in distribution of income or educational level was observed. No difference was observed in the quality of treatment – as measured by curative intent, proportion of patients resected or who died within 90 days of diagnosis.ConclusionUsing nationwide population-based data, our study reassuringly shows no adverse effects of the COVID-19 pandemic on the diagnosis, socio-economic characteristics nor quality of treatment of lung cancer, as compared to the preceding years.     

Molecular deconvolution of the neutralizing antibodies induced by an inactivated SARS-CoV-2 virus vaccine

Dear Editor, The rapid emergence and persistence of the pandemic caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) has had enormous impacts on global health and the economy.Effective vaccines against SARS-CoV-2 are urgently needed to control the coronavirus disease 2019(COVID-19) pandemic,and multiple vaccines have been found to be efficacious in preventing symptomatic COVID-19(Polack et al.,2020;Wu et al.,2020;Jones and Roy,2021).We have developed a traditional beta-propiolactone-inacti-vated aluminum hydroxide-adjuvanted whole-virion SARS-CoV-2 vaccine (BBIBP-CorV),which elicited protective immune responses in clinical trials (Wang et al.,2020;Xia et al.,2021).The vaccine has been granted conditional approvals or emergency use authorizations (EUAs) in China and other countries.     

Increased Incidence and Severity of New Graves Disease Diagnoses in Youth During the COVID-19 Pandemic

ObjectiveGraves disease (GD), an autoimmune disease of the thyroid, is likely caused by a combination of genetic predisposition and environmental triggers. Recent data suggest that COVID-19 may be associated with the development of autoimmune disease. The aim of this study was to assess the incidence and characteristics of new GD diagnoses in youth prior to and during the COVID-19 pandemic.MethodsWe performed a retrospective chart review of all new GD diagnoses in patients aged 0 to 18 years diagnosed at a tertiary care pediatric hospital between January 1, 2018, and December 31, 2021.ResultsOver a 4-year period, 51 patients had been diagnosed with new-onset GD. We observed an increased incidence in new-onset GD during the pandemic compared with that in the 2 prior years (P = .01). During the pandemic period, heart rates (P = .03) as well as systolic (P = .005) and diastolic (P = .01) blood pressures were higher at initial evaluation, patients more frequently reported palpitations (P = .03) and tremors (P = .04), and an increased proportion of patients required beta-blockade treatment at diagnosis (P = .002). The percentage of patients requiring thionamide treatment and thionamide doses had been similar over time.ConclusionWe identified an increase in new-onset pediatric GD diagnoses during the COVID-19 pandemic. In addition, youths had increased severity of symptoms and more frequently required beta-blockade treatment at diagnosis. Further study of the relationship between COVID-19 and autoimmune thyroid disease is needed.     

Health Care Disparities in Outpatient Diabetes Management During the Coronavirus Disease 2019 Pandemic: Where Do We Stand Now?

ObjectiveWe examined diabetes outpatient management during the first 2 years of the Coronavirus Disease 2019 pandemic in an endocrinology practice with a focus on health care disparities in outcomes.MethodsWe conducted a retrospective cohort study examining adults with diabetes during 3 time periods: T1 (March 2019-February 2020), T2 (March 2020-February 2021), and T3 (March 2021-February 2022). Clinical outcomes included body mass index (BMI), systolic blood pressure (SBP), Hemoglobin A1c (HgbA1c), low-density lipoprotein cholesterol (LDL), and urine albumin:creatinine ratio. Appointment types (virtual vs in-person) were also collected.ResultsFrequencies of HgbA1c, BMI, and SBP measurements reduced by 36.0%, 46.3%, and 48.5% in T2, respectively, and remaining 8.7% (HgbA1c), 13.4% (BMI), and 15.2% (SBP) lower at the end of the study period (P < .001) compared to prepandemic levels. However, the average HgbA1c and LDL slightly improved. Clinic appointments per patient increased during the pandemic, fueled by telehealth utilization. Women had fewer in-person visits during T2, those older than 65 had better HgbA1c, and the most socioeconomically deprived group had the worst HgbA1c during every time period. In addition, black patients had worse HgbA1c, LDL, and SBP values throughout the study, which did not worsen over the pandemic.ConclusionWhile the frequency of health measurements had not fully recovered 2 years into the pandemic, this did not translate to worse diabetes management or a widening of pre-existing disparities. Our study emphasizes the role of equitable health care in minimizing inequalities in diabetes, particularly during times of crisis.     

Variations in length of stay of inpatients with COVID-19: A nationwide test of the new model of care under vision 2030 in Saudi Arabia

ObjectiveThe coronavirus disease 2019 (COVID-19) has impacted the Kingdom of Saudi Arabia (KSA) as it has other nations. However, length of stay (LOS), as a healthcare quality indicator, has not been examined across the healthcare regions in the KSA. Therefore, this study aimed to examine factors associated with LOS to better understand the Saudi Health System's performance in response to the COVID-19 pandemic in the newly suggested five Saudi regional business units (BUs).MethodsA retrospective study was conducted using Ministry of Health (MOH) data on hospital LOS during the period from March to mid-July 2020. Participants were adult inpatients (18 years or older) with confirmed COVID-19 (n = 1743 patients). The 13 regions of the KSA were united into the defined five regional BUs during the reorganization of the health system. Covariates included demographics such as age and sex, comorbidities, and complications of COVID-19. A multiple linear regression with stepwise forward selection was used to model LOS for other explanatory variables associated with LOS, including demographic, comorbidities, and complications.ResultsThe mean LOS was 11.85 days which differed significantly across the BUs, ranging from 9.3 days to 13.3 days (p value < 0.001). BUs differed significantly in LOS for transferred patients but not for patients in the intensive care unit (ICU) or those who died in-hospital. The multiple regression analysis revealed that the LOS for inpatients admitted in the Eastern and Southern BUs was significantly shorter than for those in the Central BU. (p value < 0.001). Admission to the ICU was associated with lengthier stays (p value < 0.0001). Factors significantly associated with shorter stays (compared to the reference), were being Saudi, death during admission, and patients referred to another hospital (p value < 0.05).ConclusionThe LOS for patients with COVID-19 differed across the proposed regional healthcare BUs, suggesting regional differences in quality of care under the reorganization of the national health system. Since patient and disease characteristics did not explain these findings, differences in staffing and other resources need to be examined to develop interventions.     

Impact of meteorological factors and population density on COVID-19 pandemic in Saudi Arabia

Transmission and increase in cases and fatalities of coronavirus disease-2019 (COVID-19) are significantly influenced by the parameters of weather, human activities and population factors. However, study gap on the seasonality of COVID-19 and impact of environmental factors on the pandemic in Saudi Arabia is present. The main aim of the study is to evaluate the impact of environment on the COVID-19 pandemic. Data were analyzed from January 2020 to July 2021. The generalized estimating equation (GEE) was used to determine the effect of environmental variables on longitudinal outcomes. Spearman's rank correlation coefficient (r_s) was used to analyze the impact of different parameters on the outcome of the pandemic. Multiple sequence alignment was performed by using ClustalW. Vaccination and fatalities (r_s = ?0.85) had the highest association followed by vaccination with cases (r_s = ?0.81) and population density with the fatalities (r_s = 0.71). The growth rate had the highest correlation with sun hours (r_s = ?0.63). Isolates from variant of concern alpha and beta were detected. Most of the reference sequences in Saudi Arabia were closely related with B.1.427/429 variant. Clade GH (54%) was the most prevalent followed by O (27%), GR (9%), G (6%), and S (4%), respectively. Male to female patient ratio was 1.4:1. About 95% fatality and hospitalization were reported in patients aged >60 years. This study will create a comprehensive insight of the interaction of environmental factors and the pandemic and add knowledge on seasonality of COVID-19 in Saudi Arabia.     

新冠疫情对全球生物多样性热点地区森林面积的影响

森林是维持生物多样性的重要保障,森林面积的损失常常会导致区域生物多样性的降低或丧失。为探讨新冠疫情对全球生物多样性的影响,该文利用Image J软件筛选出全球生物多样性热点地区占国土面积超60%的国家作为研究对象,以全球生物多样性热点地区的森林损失面积、生物多样性完整性数据、年度(2020年和2021年)新冠疫情感染数据、国内生产总值(GDP)为研究对象,进行关联分析、线性混合效应模型构建和回归预测。结果表明:虽然新冠病毒的每百万人口感染数量与森林损失面积表现为显著负相关,具体表现为新冠疫情显著减少了因城市和农业大规模扩张而导致的森林损失面积,但在新冠疫情暴发的2年(2020年和2021年)期间,全球生物多样性热点地区的森林损失总量仍然持续上升,主要原因是新冠疫情间接加速了人工林和天然林的采伐。回归模型预测显示,新冠疫情期间,全球生物多样性热点地区的森林损失面积在2020年和2021年分别增加了5.83%和21.78%。综上表明,虽然新冠疫情对生物多样性热点地区的森林损失具有一定的抑制作用,但森林损失面积仍然在增加。该研究结果为制定生物多样性的保护措施提供了数据支撑。     

Japanese cancer screening programs during the COVID-19 pandemic: Changes in participation between 2017-2020

BackgroundThe impact of the coronavirus disease 2019 (COVID-19) pandemic on cancer screening participation is a global concern. A national database of screening performance is available in Japan for population-based cancer screening, estimated to cover approximately half of all cancer screenings.MethodsUtilizing the fiscal year (FY) 2017–2020 national database, the number of participants in screenings for gastric cancer (upper gastrointestinal [UGI] series or endoscopy), colorectal cancer (fecal occult blood test), lung cancer (chest X-ray), breast cancer (mammography), and cervical cancer (Pap smear) were identified. The percent change in the number of participants was calculated.ResultsCompared with the pre-pandemic period (FY 2017–2019), in percentage terms FY 2020 recorded the largest decline in gastric cancer UGI series (2.82 million to 1.91 million, percent change was −32.2 %), followed by screening for breast cancer (3.10 million to 2.57 million, percent change was −17.2 %), lung cancer (7.92 million to 6.59 million, percent change was −16.7 %), colorectal cancer (8.42 million to 7.30 million, percent change was −13.4 %), cervical cancer (4.26 million to 3.77 million, percent change was −11.6 %), and gastric cancer via endoscopy (1.02 million to 0.93 million, percent change was −9.0 %).ConclusionThe number of participants in population-based screenings in Japan decreased by approximately 10–30 % during the pandemic. The impact of these declines on cancer detection or mortality should be carefully monitored.     

Sick Euthyroid Syndrome on Presentation of Patients With COVID-19: A Potential Marker for Disease Severity

ObjectivePrecise risk stratification and triage of coronavirus disease 2019 (COVID-19) patients are essential in the setting of an overwhelming pandemic burden. Clinical observation has shown a somewhat high prevalence of sick euthyroid syndrome among patients with COVID-19. This study aimed to evaluate the predictive value of free triiodothyronine (FT3) at the clinical presentation of COVID-19 for disease severity and death.MethodsThis retrospective cohort study was based on electronic medical records. The study was conducted at Sheba Medical Centre, a tertiary hospital where several acute and chronic wards have been dedicated to the treatment of patients with COVID-19. The primary outcome measure was death during hospitalization; secondary outcomes included hospitalization in intensive care, mechanical ventilation, and length of hospitalization.ResultsOf a total of 577 polymerase chain reaction-positive patients with COVID-19 hospitalized between February 27 and July 30, 2020, 90 had at least 1 measurement of thyroid-stimulating hormone, free thyroxine, and FT3 within 3 days of presentation. After applying strict exclusion criteria, 54 patients were included in the study. Patients in the lowest tertile of FT3 had significantly higher rates of mortality (40%, 5.9%, and 5.9%, P = .008), mechanical ventilation (45%, 29.4%, and 0.0%; P = .007) and intensive care unit admission (55%, 29.4%, and 5.9%, P = .006). In multivariate analyses adjusted for age, Charlson comorbidity index, creatinine, albumin, and white blood cell count. FT3 remained a significant independent predictor of death.ConclusionFT3 levels can serve as a prognostic tool for disease severity in the early presentation of COVID-19.     

Knowledge,attitude and practices of healthcare professionals of Riyadh,Saudi Arabia towards covid-19: A cross-sectional study

Background & objectivesCOVID-19 is an emerging pandemic that necessitates the implementation of effective infection prevention and control steps. The knowledge, attitudes, and practices (KAP) of healthcare professionals toward COVID-19 affect their compliance to prevention and control initiatives. During the evolving pandemic, we examined the KAP among healthcare professionals against COVID-19 in this research.Materials and methodsThis was a cross-sectional study conducted among Riyadh region health care professionals from the beginning of December 2020 to the end of February 2021 using a validated self-administered questionnaire. The knowledge questionnaire contained questions about COVID-19 clinical characteristics, prevention, and management. The evaluation of attitudes and practices included questions regarding actions and adjustments in COVID-19 response activities. Knowledge scores were measured and compared using demographic characteristics, as well as attitudes and practices toward COVID-19. Using SPSS-IBM 25, bivariate statistics were done to analyze the data.Results146 healthcare professionals completed the survey. Physicians were the most prominent party in the survey, accounting for 74 (51 percent), followed by nurses 44 (30 percent) and pharmacists 28 (19 percent). The participants' average age was 39.69 ± 8.48 years. The participant's mean knowledge, attitude, and practice scores were 11.43 ± 1.34, 3.89 ± 0.93, and 3.85 ± 0.81, respectively. With a positive attitude, the mean knowledge score was 11.52, and with proper practice, it was 11.32. With an improvement in knowledge, the attitude score increased significantly (r = 0.172, P = 0.001). Besides, there was a greater association between attitudes and practices (r = 0.170, P = 0.029). A significant enhancement in the practice score of the professionals was noted with an increase in knowledge score (r = 0.095, P = 0.010), an indicator for a positive correlation between practice and knowledge scores.Interpretation & conclusionHealthcare practitioners have a good understanding of COVID-19. Improved knowledge and a positive attitude toward COVID-19 infection are linked to appropriate practice. There is a need for more manpower, better COVID-19 management training, and strategies to reduce anxiety among healthcare professionals.
