by Ye Ji Lee, Min A. Yuh, In Soo Kim, Byul Nym Hee Cho, Seon Hee Woo, Sungyoup Hong Background People experienced various stress and psychological responses to the coronavirus disease 2019 (COVID-19) pandemic. This study aimed to examine the changes in emergency medical services (EMSs) utilization by self-harm patients in early pandemic and the impacts of physical distancing measures on the EMSs utilization by self-harm patients. Methods Data for all patients presenting to emergency departments (EDs) after self-harm injuries including self-poisoning were collected from the National ED Information System (NEDIS). Characteristics of patients in two study regions (urban versus rural) were compared. Weekly and annual ED visit rates after self-harm (VRSH) per 100,000 population were calculated. Mobile phone mobility index (MPMI) was calculated by dividing a region’s aggregated mobile phone mobility by mid-year population. Joinpoint regression analysis was conducted to assess changes in 2020 over pre-pandemic years. Test for presence of joinpoint at the end of 2019 was performed. A cross-correlation function was used to estimate the maximal morphological similarity and lag time between changes in MPMI and VRSH. Results In 2020, in early phases of the pandemic, there was a moderate decline in self-harm-related ED visits to 30,797 from a continuously increasing trend seen in previous years. However, proportions of young people (50.1%) and females (62.3%) increased over previous years. VRSHs among women and young people aged 15–34 years showed higher levels in 2020 than in previous five years. There was a significant decrease in the proportion of patients transported directly from the scene. In addition, there was a polarization of mental state upon ED arrival from alert and unresponsive. The median correlation coefficient between MPMI values and VRSH values was 0.601 (interquartile range [IQR]: 0.539–0.619) in urban regions and 0.531 (IQR: 0.454–0.595) in rural regions, showing no statistically significant difference between the two. Conclusion Physical distancing measures adopted to prevent the spread of transmittable diseases following the pandemic had the effect of decreasing ED visits due to self-harm. When the pandemic has ended, and daily life has been restored, it will be particularly important to pay attention to the increased numbers of self-harm patients expected to visit EDs compared to during the pandemic.

by Yingjun Nie, Yuanyan Ma, Xiaozhi Yao, Yijia Gao, Xiangping Zheng Background COVID-19 caused severe effects on the psychological well-being of Chinese students overseas (COS). Physical activity (PA) is critical to strengthen immunity, prevent infection, and reduce the psychological burden caused by COVID-19. However, there is a severe lack of effective PA intervention for mental health in most countries, and COS have limited access to mental healthcare during the pandemic. Objective We aim to examine the effects of PA on COS’ mental health during the pandemic abroad and to better understand that certain types of PA might be associated with a greater reduction in psychological burdens during the pandemic. Methods and results In a multi-country cross-sectional analysis, a questionnaire was distributed to COS living in 37 foreign countries via WeChat Subscription using a snowball sampling strategy. A total of 10,846 participants were included. Descriptive statistics and Binary logistic regression analysis were used for statistical analysis. We found that COS had negative psychology during the pandemic, especially with fear (2.90, 95% CI 2.88−2.92), anxiety (2.84, 95% CI 2.82−2.85), and stress (2.71, 95% CI 2.69−2.73). PA had meaningful effects on reducing COS self-reported mental health burdens (3.42, 95% CI 3.41–3.44) during the pandemic. The largest associations were seen for recreational and home-based PA (i.e., family games, home aerobic exercise), individual outdoor PA (i.e., walking or running, rope skipping), and PA with a duration of 30 to 70 min per session at frequencies of 4 to 6 times and a total of 150 to 330 min of moderate and vigorous intensity per week tends to be an optimal choice during social distancing times. Conclusions COS had several poor mental health conditions during the pandemic. The improvement of PA on COS’ psychology was positively effective during the pandemic. Specific types, intensities, durations, and frequencies of PA might have advantages over others for improving COS’ mental health during periods of public health emergencies, and the topic may merit interventional study to reveal multiple factors causing COS’ psychological burdens and enrich the PA forms for all COS’ mental health improvement (i.e., infected, recovered, and asymptomatic COS).

by Amir Hossein Khoshakhlagh, Saeid Yazdanirad, Hamid Reza Saberi, Masoud Motalebi Kashani, Fatemeh Ghanaei Khaledabadi, Fazel Mohammadi-Moghadam, Muhammet Gul The need for a biological disease risk assessment method to prevent the contagion of these diseases, particularly among healthcare personnel, is crucial. Therefore, this study aimed to develop and validate a biological risk assessment tool for biological agents among hospital personnel under COVID-19 conditions. This cross-sectional study was performed on 301 employees in two hospitals. Firstly, we identified the items affecting the contagion of biological agents. Then, we computed the weight of the items using the Fuzzy Analytical Hierarchy Process (FAHP) method. We used the identified items and the estimated weights in the next step to develop a predictive equation. The outcome of this tool was the risk score of biological disease contagion. After that, we used the developed method to evaluate the biological risk of the participants. The ROC curve was also used to reveal accuracy of developed method. In this study, 29 items were identified and categorized into five dimensions, including environmental items, ventilation items, job items, equipment-related items, and organizational items. The weights of these dimensions were estimated at 0.172, 0.196, 0.255, 0.233, and 0.144, respectively. The final weight of items was used to develop a predictive equation. The area under ROC curves (AUC) was also calculated as 0.762 (95% CI: 0.704, 0.820) (p

Brown, Hemda Garelick, Jan Hofman, Barbara Kasprzyk-Hordern, Azeem Majeed, Sally Priest, Hubert Denise, Mohammad Khalifa, Irene Bassano, Matthew J. Wade, Jasmine Grimsley, Lian Lundy, Andrew C. Singer, Mariachiara Di Cesare Background Schools are high-risk settings for infectious disease transmission. Wastewater monitoring for infectious diseases has been used to identify and mitigate outbreaks in many near-source settings during the COVID-19 pandemic, including universities and hospitals but less is known about the technology when applied for school health protection. This study aimed to implement a wastewater surveillance system to detect SARS-CoV-2 and other public health markers from wastewater in schools in England. Methods A total of 855 wastewater samples were collected from 16 schools (10 primary, 5 secondary and 1 post-16 and further education) over 10 months of school term time. Wastewater was analysed for SARS-CoV-2 genomic copies of N1 and E genes by RT-qPCR. A subset of wastewater samples was sent for genomic sequencing, enabling determination of the presence of SARS-CoV-2 and emergence of variant(s) contributing to COVID-19 infections within schools. In total, >280 microbial pathogens and >1200 AMR genes were screened using RT-qPCR and metagenomics to consider the utility of these additional targets to further inform on health threats within the schools. Results We report on wastewater-based surveillance for COVID-19 within English primary, secondary and further education schools over a full academic year (October 2020 to July 2021). The highest positivity rate (80.4%) was observed in the week commencing 30th November 2020 during the emergence of the Alpha variant, indicating most schools contained people who were shedding the virus. There was high SARS-CoV-2 amplicon concentration (up to 9.2x106 GC/L) detected over the summer term (8th June - 6th July 2021) during Delta variant prevalence. The summer increase of SARS-CoV-2 in school wastewater was reflected in age-specific clinical COVID-19 cases. Alpha variant and Delta variant were identified in the wastewater by sequencing of samples collected from December to March and June to July, respectively. Lead/lag analysis between SARS-CoV-2 concentrations in school and WWTP data sets show a maximum correlation between the two-time series when school data are lagged by two weeks. Furthermore, wastewater sample enrichment coupled with metagenomic sequencing and rapid informatics enabled the detection of other clinically relevant viral and bacterial pathogens and AMR. Conclusions Passive wastewater monitoring surveillance in schools can identify cases of COVID-19. Samples can be sequenced to monitor for emerging and current variants of concern at the resolution of school catchments. Wastewater based monitoring for SARS-CoV-2 is a useful tool for SARS-CoV-2 passive surveillance and could be applied for case identification and containment, and mitigation in schools and other congregate settings with high risks of transmission. Wastewater monitoring enables public health authorities to develop targeted prevention and education programmes for hygiene measures within undertested communities across a broad range of use cases.

Influenza is an acute respiratory infection caused by influenza viruses that circulate worldwide. The annual epidemics are estimated to result in about 3 to 5 million cases of severe illness, and about 290 000 to 650 000 respiratory deaths in the world [1]. In addition, 4.8%-18.9% of children with influenza develop various neurologic complications, including febrile seizure, influenza-associated encephalopathy/encephalitis, transverse myelitis, Guillain-Barré syndrome, and Reye\'s syndrome [2, 3].

Background: The COVID-19 pandemic led to an increase in the number of deaths among all populations, including people with diagnosed HIV (PWDH). The aim of this study was to analyze the top causes of death (COD) among PWDH prior to the start of the COVID-19 pandemic, during the start of the COVID-19 pandemic, and a year later, to determine changes in the leading COD among PWDH, as well as determine if the historical trend of decreasing deaths related to HIV continued through the pandemic. Methods: To examine mortality among PWDH in New York State (NYS), records for PWDH who died from 2015-2021 were extracted from the NYS HIV registry and Vital Statistics Death Data. Results: The number of deaths among PWDH in New York State (NYS) increased 32% from 2019 to 2020 and continued in 2021. COVID-19 was one of the most common underlying COD among PWDH in 2020. In 2021, COVID-19 related deaths decreased while HIV and diseases of the circulatory system remained the top COD. HIV listed as either the underlying or contributing COD showed a consistent downward trend in the percentage of HIV related deaths among PWDH, from 45% in 2015 to 32% in 2021. Conclusions: There was a large increase in deaths among PWDH in 2020, with a substantial percent related to COVID-19. However, even with the introduction of COVID-19 in 2020, the percentage of deaths related to HIV— one of the goals of the Ending the Epidemic Initiative in NYS—continued to decrease.

Objectives: To determine the impact of high doses of corticosteroids (HDCT) in critically ill COVID-19 patients with nonresolving acute respiratory distress syndrome (ARDS) who had been previously treated with dexamethasone as a standard of care. Design: Prospective observational cohort study. Eligible patients presented nonresolving ARDS related to severe acute respiratory syndrome coronavirus 2 infection and had received initial treatment with dexamethasone. We compared patients who had received or not HDCT during ICU stay, consisting of greater than or equal to 1 mg/kg of methylprednisolone or equivalent for treatment of nonresolving ARDS. The primary outcome was 90-day mortality. We assessed the impact of HDCT on 90-day mortality using univariable and multivariable Cox regression analysis. Further adjustment for confounding variables was performed using overlap weighting propensity score. The association between HDCT and the risk of ventilator-associated pneumonia was estimated using multivariable cause-specific Cox proportional hazard model adjusting for pre-specified confounders. Setting: We included consecutive patients admitted in 11 ICUs of Great Paris area from September 2020 to February 2021. Patients: Three hundred eighty-three patients were included (59 in the HDCT group, 324 in the no HDCT group). Interventions: None. Measurements and Main Results: At day 90, 30 of 59 patients (51%) in the HDCT group and 116 of 324 patients (35.8%) in the no HDCT group had died. HDCT was significantly associated with 90-day mortality in unadjusted (hazard ratio [HR], 1.60; 95% CI, 1.04–2.47; p = 0.033) and adjusted analysis with overlap weighting (adjusted HR, 1.65; 95% CI, 1.03–2.63; p = 0.036). HDCT was not associated with an increased risk of ventilator-associated pneumonia (adjusted cause-specific HR, 0.42; 95% CI, 0.15–1.16; p = 0.09). Conclusions: In critically ill COVID-19 patients with nonresolving ARDS, HDCT result in a higher 90-day mortality.

Although the bacille Calmette-Guérin (BCG) vaccine is used primarily to protect against tuberculosis, previous research has suggested it might also guard against other infections. At the start of the COVID-19 pandemic, researchers hypothesized that vaccination with BCG, which seems to cause epigenetic changes in immune cells that promote a stronger immune response against pathogens, might be effective against COVID-19.

Griffiths, Scholastic Ashaba Background Students in sub-Saharan African countries experienced online classes for the first time during the COVID-19 pandemic. For some individuals, greater online engagement can lead to online dependency, which can be associated with depression. The present study explored the association between problematic use of the internet, social media, and smartphones with depression symptoms among Ugandan medical students. Methods A pilot study was conducted among 269 medical students at a Ugandan public university. Using a survey, data were collected regarding socio-demographic factors, lifestyle, online use behaviors, smartphone addiction, social media addiction, and internet addiction. Hierarchical linear regression models were performed to explore the associations of different forms of online addiction with depression symptom severity. Results The findings indicated that 16.73% of the medical students had moderate to severe depression symptoms. The prevalence of being at risk of (i) smartphone addiction was 45.72%, (ii) social media addiction was 74.34%, and (iii) internet addiction use was 8.55%. Online use behaviors (e.g., average hours spent online, types of social media platforms used, the purpose for internet use) and online-related addictions (to smartphones, social media, and the internet) predicted approximately 8% and 10% of the severity of depression symptoms, respectively. However, over the past two weeks, life stressors had the highest predictability for depression (35.9%). The final model predicted a total of 51.9% variance for depression symptoms. In the final model, romantic relationship problems (ß = 2.30, S.E = 0.58; p

by Sofie J. Lorijn, Lydia Laninga-Wijnen, Maaike C. Engels, Gerine M. A. Lodder, René Veenstra The COVID-19 measures raised societal concerns about increases in adolescents’ loneliness. This study examined trajectories of adolescents’ loneliness during the pandemic, and whether trajectories varied across students with different types of peer status and contact with friends. We followed 512 Dutch students (Mage = 11.26, SD = 0.53; 53.1% girls) from before the pandemic (Jan/Feb 2020), over the first lockdown (March-May 2020, measured retrospectively), until the relaxation of measures (Oct/Nov 2020). Latent Growth Curve Analyses (LGCA) showed that average levels of loneliness declined. Multi-group LGCA showed that loneliness declined mostly for students with a victimized or rejected peer status, which suggests that students with a low peer status prior to the lockdown may have found temporary relief from negative peer experiences at school. Students who kept all-round contact with friends during the lockdown declined in loneliness, whereas students who had little contact or who did not (video) call friends did not.

by Aldo Córdova-Palomera, Csaba Siffel, Chris DeBoever, Emily Wong, Dorothée Diogo, Sandor Szalma As findings on the epidemiological and genetic risk factors for coronavirus disease-19 (COVID-19) continue to accrue, their joint power and significance for prospective clinical applications remains virtually unexplored. Severity of symptoms in individuals affected by COVID-19 spans a broad spectrum, reflective of heterogeneous host susceptibilities across the population. Here, we assessed the utility of epidemiological risk factors to predict disease severity prospectively, and interrogated genetic information (polygenic scores) to evaluate whether they can provide further insights into symptom heterogeneity. A standard model was trained to predict severe COVID-19 based on principal component analysis and logistic regression based on information from eight known medical risk factors for COVID-19 measured before 2018. In UK Biobank participants of European ancestry, the model achieved a relatively high performance (area under the receiver operating characteristic curve ~90%). Polygenic scores for COVID-19 computed from summary statistics of the Covid19 Host Genetics Initiative displayed significant associations with COVID-19 in the UK Biobank (p-values as low as 3.96e-9, all with R2 under 1%), but were unable to robustly improve predictive performance of the non-genetic factors. However, error analysis of the non-genetic models suggested that affected individuals misclassified by the medical risk factors (predicted low risk but actual high risk) display a small but consistent increase in polygenic scores. Overall, the results indicate that simple models based on health-related epidemiological factors measured years before COVID-19 onset can achieve high predictive power. Associations between COVID-19 and genetic factors were statistically robust, but currently they have limited predictive power for translational settings. Despite that, the outcomes also suggest that severely affected cases with a medical history profile of low risk might be partly explained by polygenic factors, prompting development of boosted COVID-19 polygenic models based on new data and tools to aid risk-prediction.

Abstract Background Besides impaired respiratory function and immune system, COVID-19 can affect renal function from elevated blood urea nitrogen (BUN) or serum creatinine (sCr) levels to acute kidney injury (AKI) and renal failure. This study aims to investigate the relationship between Cystatin C and other inflammatory factors with the consequences of COVID-19. Methods A total of 125 patients with confirmed Covid-19 pneumonia were recruited in this cross-sectional study from March 2021 to May 2022 at Firoozgar educational hospital in Tehran, Iran. Lymphopenia was an absolute lymphocyte count of less than 1.5 × 109/L. AKI was identified as elevated serum Cr concentration or reduced urine output. Pulmonary consequences were evaluated. Mortality was recorded in the hospital one and three months after discharge. The effect of baseline biochemical and inflammatory factors on odds of death was examined. SPSS, version 26, was used for all analyses. P-vale less than 0.05 was considered significant. Results The highest amount of co-morbidities was attributed to COPD (31%; n = 39), dyslipidemia and hypertension (27%; n = 34 for each) and diabetes (25%; n = 31). The mean baseline cystatin C level was 1.42 ± 0.93 mg/L, baseline creatinine was 1.38 ± 0.86 mg/L, and baseline NLR was 6.17 ± 4.50. Baseline cystatin C level had a direct and highly significant linear relationship with baseline creatinine level of patients (P

Background: Data supporting dementia as a risk factor for COVID-19 mortality relied on ICD-10 codes, yet nearly 40% of individuals with probable dementia lack a formal diagnosis. Dementia coding is not well-established for people with HIV (PWH), and its reliance may affect risk assessment. Methods: This retrospective cohort analysis of PWH with SARS-CoV-2 polymerase chain reaction positivity includes comparisons to people without HIV (PWoH), matched by age, sex, race, and zipcode. Primary exposures were dementia diagnosis, by ICD-10 codes, and cognitive concerns, defined as possible cognitive impairment up to 12 months before COVID-19 diagnosis after clinical review of notes from the electronic health record. Logistic regression models assessed the effect of dementia and cognitive concerns on odds of death (OR [95% confidence interval]); models adjusted for VACS Index 2.0. Results: Sixty-four PWH were identified out of 14,129 patients with SARS-CoV-2 infection and matched to 463 PWoH. Compared to PWoH, PWH had a higher prevalence of dementia (15.6% vs. 6%, p = 0.01) and cognitive concerns (21.9% vs. 15.8%, p = 0.04). Death was more frequent in PWH (p

Abstract Introduction Objectives of this study, as part of a nation-wide HIV pre-exposure prophylaxis (PrEP) evaluation project, were to determine the incidence of infections with HIV, chlamydia, gonorrhea, syphilis, hepatitis A/B/C in persons using PrEP, and to describe the health care funded PrEP use in Germany. Additionally, factors associated with chlamydia/gonorrhea and syphilis infections were assessed. Methods Anonymous data of PrEP users were collected at 47 HIV-specialty centers from 09/2019–12/2020. Incidence rates were calculated per 100 person years (py). Using longitudinal mixed models, we analyzed risk factors associated with sexually transmitted infections (STIs). Results 4620 PrEP users were included: 99.2% male, median age 38 years (IQR 32–45), 98.6% men who have sex with men (MSM). The median duration of PrEP exposure was 451 days (IQR 357–488), totaling 5132 py. Four HIV infections were diagnosed, incidence rate 0,078/100py (95% CI 0.029–0.208). For two, suboptimal adherence was reported and in the third case, suboptimal adherence and resistance to emtricitabine were observed. One infection was likely acquired before PrEP start. Incidence rates were 21.6/100py for chlamydia, 23.7/100py for gonorrhea, 10.1/100py for syphilis and 55.4/100py for any STI and decreased significantly during the observation period. 65.5% of syphilis, 55.6% of chlamydia and 50.1% of gonorrhea cases were detected by screening of asymptomatic individuals. In a multivariable analysis among MSM younger age, PrEP start before health insurance coverage and daily PrEP were associated with greater risk for chlamydia/gonorrhea. Symptom triggered testing and a history of STI were associated with a higher risk for chlamydia/gonorrhea and syphilis. A significantly lower risk for chlamydia/gonorrhea and syphilis was found for observations during the COVID-19 pandemic period. Conclusions We found that HIV-PrEP is almost exclusively used by MSM in Germany. A very low incidence of HIV infection and decreasing incidence rates of STIs were found in this cohort of PrEP users. The results were influenced by the SARS-CoV-2 pandemic. Rollout of PrEP covered by health insurance should be continued to prevent HIV infections. Increased PrEP availability to people at risk of HIV infection through the elimination of barriers requires further attention. Investigation and monitoring with a longer follow-up would be of value.

To assess DDS (Doctor of Dental Surgery) graduation exams, this study analyzed their 2021 implementation in comparison to onsite exams conducted in 2020 and 2022 at the Faculty of Odonto-Stomatology, University of Medicine and Pharmacy at Ho Chi Minh City, Viet Nam (FOS-UMPH). The final online examination comprises two main sessions: a synchronous online examination using FOS-UMPH e-Learning for theories (consisting of 200 MCQs and 3 written tests with 3 clinical situations needed be solved) and a synchronous online examination using Microsoft Teams for practicum (comprising of 12 online OSCE stations). The final grades were evaluated using the same metrics in face-to-face final examinations in 2022 and 2020. A total of 114, 112 and 95 students were recruited for the first-time exams in 2020, 2021 and 2022, respectively. In order to analyze the reliability, histogram and k-mean clustering were employed. The histograms from 2020, 2021 and 2022 showed a striking similarity. However, fewer students failed in 2021 and 2022 (13% and 12.6%, respectively) compared to 2020 (28%), with clinical problem-solving part grades (belonging to theory session) being notably higher in 2021 and 2022. Intriguingly, the MCQ Score results showed the identical patterns. The courses of orthodontics, dental public health, and pediatrics subjects (in the group of prevention and development dentistry) stood out for their exceptional accuracy across both sessions. After examining data gathered over three years, we identified three distinct clusters: the first comprised of scattered average and low scores, the second characterized by high scores but unstable and scattered and the third cluster boasting consistently high and centered scores. According to our study, online and onsite traditional graduation exam results are relatively equivalent, but additional measures are necessary to standardize the final examination and adapt to the new normal trend in dental education.

by Anja Davis Norbye, Erlend Hoftun Farbu, Christoffer Lilja Terjesen, Nils Fleten, Anje Christina Höper Background Concerns about disease and an increase in health anxiety levels are expected consequences of the COVID-19 pandemic. However, there have been few longitudinal studies of health anxiety in the general population during this time period. The aim of this study was to examine health anxiety levels before and during the COVID-19 pandemic in an adult, working population in Norway. Material and methods This study included 1012 participants aged 18–70 years with one or more measurements of health anxiety (1402 measurements total) from the pre-pandemic period (2015 to March 11, 2020) and/or during the COVID-19 pandemic (March 12, 2020 to March 31, 2022). Health anxiety was measured with the revised version of the Whiteley Index-6 scale (WI-6-R). We estimated the effect of the COVID-19 pandemic on health anxiety scores with a general estimation equation analysis, and age, gender, education, and friendship were included in subgroup analyses. Results We found no significant change in health anxiety scores during the COVID-19 pandemic compared to the pre-pandemic period in our adult, working population. A sensitivity analysis restricted to participants with two or more measurements showed similar results. Moreover, the effect of the COVID-19 pandemic on health anxiety scores was not significant in any subgroup analysis. Conclusion Health anxiety remained stable, with no significant change observed between the pre-pandemic period and the first 2 years of the COVID-19 pandemic in an adult, working population in Norway.

Abstract Background Coagulopathy is still a serious pattern of coronavirus-19 disease. We aimed to evaluate COVID-19-associated coagulopathy and multiple hemostatic markers in Egyptian patients. In addition, to assess coagulation acute phase reactants and its effect on the outcome. Methods The study included 106 COVID-19 patients, and 51 controls. All patients were positive for COVID-19 infection by nasopharyngeal swab for detection of viral RNA by real-time PCR. In addition to baseline data and radiological findings, the coagulation profile was done with special attention to Fibrinogen, d-dimer, Factor VIII, von Willebrand factor (VWF), Protein C, Protein S, Antithrombin III (ATIII) and Lupus anticoagulant (LA)-1 and 2. Results The results showed significantly higher VWF, d-dimer, and LA1 (screening) and LA2 (confirmation) in patients than a control group. Significantly higher d-dimer FVIII, VWF and LA1-2 were detected in the severe group. ATIII had high diagnostic accuracy in severity prediction. We found a significantly higher international randomized ratio (INR) and VWF among patients with thrombotic events. For prediction of thrombosis; VWF at cutoff > 257.7 has 83.3% sensitivity and 83.3% specificity. Conclusion Patients with COVID-19 infection are vulnerable to different forms of coagulopathy. This could be associated with poor outcomes. d-Dimer is a chief tool in diagnosis, severity evaluation but not thrombosis prediction. Early screening for this complication and its proper management would improve the outcome.

ObjectivesTo describe and compare the initial clinical characteristics of a cohort of patients with suspected COVID-19 managed by general practitioners (GPs); to assess whether 3-month persistent symptoms were more frequent among confirmed cases than among no-COVID cases; and to identify factors predictive of persistent symptoms and adverse outcomes among confirmed cases. Design and settingA comparative, prospective, multicentre cohort study in primary care in the Paris region of France. Participants521 patients aged ≥18 with suspected COVID-19 were enrolled between March and May 2020. Outcome measuresInitial symptoms, COVID-19 status, persistent symptoms 3 months after inclusion and a composite criterion for potentially COVID-19-related events (hospitalisation, death, emergency department visits). The final COVID-19 status (‘confirmed’, ‘no-COVID’ and ‘uncertain’ cases) was determined by the GP after the receipt of the laboratory test results. Results516 patients were analysed; 166 (32.2%) were classified into the ‘confirmed COVID’ group, 180 (34.9%) into the ‘no-COVID’ group and 170 (32.9%) in the ‘uncertain COVID’ group. Confirmed cases were more likely to have persistent symptoms than no-COVID cases (p=0.09); initial fever/feeling feverish and anosmia were independently associated with persistent symptoms. At 3 months, we observed 16 (9.8%) COVID-19-related hospital admissions, 3 (1.8%) intensive care unit admissions, 13 (37.1%) referrals to an emergency department and no death. Age >70 and/or at least one comorbidity (OR 6.53; 95% CI 1.13–37.84; p=0.036), abnormalities in a lung examination (15.39; 95% CI 1.61–146.77; p=0.057) and two or more systemic symptoms (38.61; 95% CI 2.30–647.40; p=0.011) were associated with the composite criterion. ConclusionsAlthough most patients with COVID-19 in primary care had mild disease with a benign course, almost one in six had persistent symptoms at 3 months. These symptoms were more frequent in the ‘confirmed COVID’ group. Our findings need to be confirmed in a prospective study with longer follow-up.

AbstractBackgroundIt is unknown whether convalescent immunoglobulins (cIgG) are better than convalescent plasma (CP) for COVID-19 patients.MethodsIn this randomized trial we assigned high risk COVID-19 with ≤10 days of symptoms, to receive cIgG or CP. The primary endpoint was improvement on day 14 according to the WHO scale. Secondary endpoints were survival on day 14, and improvement, survival, and percent of ventilated patients on day 28 and treatment response in unvaccinated and vaccinated patients.Results319 patients were included; 166 received cIgG, and 153 CP. Median age was 64-66 years. 112 patients (67.5%) in the cIgG and 103 patients (67.3%) in the CP group reached the primary endpoint. Difference between groups was 0.1 (95%CI -10.1-10.4, p=0.026), failing to reach non-inferiority.

by Milla Summanen, Mikko Kosunen, Ville Kainu, Anniina Cansel, Severi Niskanen, Lalli Nurmi, Riikka-Leena Leskelä, Outi Isomeri Ever since COVID-19 was announced as a global pandemic in March 2020, healthcare systems around the world have struggled with the burden of the disease. Vaccinations and other preventive measures have decreased this burden, but severe forms of COVID-19 leading to hospitalizations and even deaths still effect certain risk groups, such as the elderly and patients with multiple comorbidities. The objective of this retrospective observational study was to identify which risk groups are at the highest risk for a severe COVID-19 infection in Finland using national registry data ranging from January 2021 to June 2022. The data was analysed in three time periods, enabling comparisons in high-risk groups between epidemiological waves caused by different variants of SARS-CoV-2. The summary level data were stratified according to predefined groups based on two criteria: age (≥18 years, 18–59 years, and ≥60 years) and risk group. The results include analysis of infection hospitalisation rate (IHR), case fatality rate (CFR) and average length of stay (LOS) in both primary and specialty care for each risk group and age group. Our results confirm that despite the decrease in COVID-19 hospitalisations and deaths observed during the study period, a significant proportion of patients are still hospitalised, and deaths occur especially in the 60+ population. Also, even though the average length of stay of hospitalised COVID-19 patients has decreased, it is still long compared to specialty care hospitalisations in general. Old age is a significant risk factor for severe COVID-19 in all patient groups and certain risk factors such as chronic kidney disease clearly increase the risk for severe COVID-19 outcomes. Early treatment should be considered with a low threshold for risk group patients and for elderly patients in order to avoid severe disease courses, and to ease the burden on hospitals where resources are currently very strained.

by Parisa Abdolrezapour, Sahar Jahanbakhsh Ganjeh, Nasim Ghanbari Motivation as a catalyst for human conduct has been associated with lots of variables. However, self-efficacy and resilience as two important components of the individuals’ psychological capital have not received enough scientific attention. This gets more significance considering the global COVID-19 pandemic with noticeable psychological consequences for the learners receiving online education. Hence, the current study proceeded to investigate the relationship between students’ self-efficacy, resilience, and academic motivation in online education. To this aim, a convenience sample of 120 university students coming from two state universities in south of Iran participated in an online survey. The questionnaires used in the survey included the self-efficacy questionnaire, resilience questionnaire, and academic motivation questionnaire. Pearson correlation and multiple regression statistical methods were applied to analyze the obtained data. The results pointed to a positive relationship between self-efficacy and academic motivation. In addition, those with a higher degree of resilience were found to experience higher academic motivation. Moreover, the results of multiple regression test revealed that self-efficacy and resilience can significantly predict the academic motivation of the students involved in an online mode of education. The research proposes a number of recommendations for developing the learners’ level of self-efficacy and resilience through enacting various pedagogical interventions. In this way, a heightened level of academic motivation would enhance EFL learners’ learning rate.

by Mónica Granja, Luís Alves, Sofia Correia Background In 2020, Portugal had high levels of unmet health care needs. Primary Care was reported as the main source of unmet needs. Objectives To describe face-to-face and remote access to GPs in Portugal during the COVID-19 pandemic. To discover patient experiences and attitudes to access to care. To identify determinants of access to care. Methods A survey of a random sample of 4,286 adults registered in a group of Family Practices was conducted in 2021. Paper questionnaires were sent by post to patients who had no e-mail address registered with the practice. Patients with an e-mail address were sent a link to an online questionnaire. Outcomes were reported waiting times for face-to-face and remote contacts with GPs, dichotomized to ascertain compliance with standards. Associations between participant characteristics and outcome variables were tested using logistic regression. Results Waiting times for face-to-face consultations with GPs during the pandemic often exceeded the maximum waiting times (MWT) set by the National Health Service. Remote contacts were mostly conducted within acceptable standards. Waiting times for speaking with the GP over the phone were rated as ‘poor’ by 40% and 27% reported requests for these calls as unmet. The odds of getting care over MWT increased for participants who reported poorer digital skills. Participants were less likely to get non-urgent consultations over MWT if they found it easy to use the online patient portal to book appointments (odds ratio 0.24; 99% confidence intervals 0.09–0.61), request prescriptions (0.18; 0.04–0.74) or insert personal data (0.18; 0.04–0.95). Conclusion Patient reported access to GPs during the pandemic was uneven in Portugal. Obtaining non-urgent consultations and remote contacts over MWT affected mainly those patients with poor digital skills. Telephone access to GPs received the worse ratings. Access through traditional pathways must remain available, to prevent the widening of inequities.

by Alden Blair, Winta Haile, Anna Muller, Luseshelo Simwinga, Richard Malirakwenda, Kimberly Baltzell Background There is a dearth of studies assessing the effects of SARS-CoV-2 on the healthcare system and access to care, especially in lower- and middle-income countries such as Malawi. We aimed to assess the impacts of COVID-19 on reported maternal and neonatal complications as well as potential changes in maternal care access to care among five primary care health facilities in Blantyre, Malawi. Methods This retrospective cohort study assessed maternal and neonatal register data from five participating health centers in Blantyre, Malawi using the Malawi District Health Information Software 2 (DHIS2) to compare outcomes from 15 months before COVID-19 emerged, defined as the pre-Covid period (January 2019 –March 2020) with nine months after COVID-19 (April 2020 –December 2020).

AbstractBackgroundFace masks have been critical in the COVID-19 pandemic, but supplies were sometimes limited and disposable masks contribute greatly to environmental waste. Studies suggest that filtration capacity is retained with repeated use, and surveys indicate many people re-use surgical masks. However, the impact of mask re-use on the host is under-studied.MethodsWe applied 16S rRNA gene sequencing to investigate the bacterial microbiome of the facial skin and oropharynx of individuals randomized to wearing fresh surgical masks daily versus masks re-used for one week.ResultsCompared to daily fresh masks, re-use was associated with increased richness (number of taxa) of the skin microbiome and trend towards greater diversity, but no difference in the oropharyngeal microbiome. Used masks had either skin-dominant or oropharynx-dominant bacterial sequences, and re-used masks had >100-fold higher bacterial content but no change in composition compared to those used for one day.ConclusionsOne week of mask re-use increased the number of low-abundance taxa on the face but did not impact the upper respiratory microbiome. Thus, face mask re-use has little impact on the host microbiome, though whether minor changes to the skin microbiome might relate to reported skin sequelae of masking (“maskne”) remains to be determined.

ObjectivesWe aim to quantify shifts in hospitalisation and mortality and how those were related to the first three phases of the epidemic and individuals’ demographics and health profile among those with a positive test for SARS-CoV-2 treated at the Mexican Social Security Institute’s facilities from March 2020 to October 2021. DesignRetrospective observational study using interrupted time series analysis to identify changes in hospitalisation rate and case fatality rate (CFR) by epidemic wave. SettingData from the Mexican Institute of Social Security’s (IMSS) Online Influenza Epidemiological Surveillance System (SINOLAVE) that include all individuals that sought care at IMSS facilities all over Mexico. ParticipantsAll individuals included in the SINOLAVE with a positive PCR or rapid test for SARS-CoV-2. Primary and secondary outcome measuresMonthly test positivity rates, hospitalisation rates, CFRs and prevalence of relevant comorbidities by age group. ResultsFrom March 2020 to October 2021, the CFR declined between 1% and 3.5%; the declines were significant for those 0–9, 20–29, 30–39, 40–49 and 70 and older. The decline was steep during the first wave and was less steep or was temporarily reversed at the beginning of the second and third waves (changes in the trend of about 0.3% and 3.8%, and between 0.7% and 3.8%, respectively, for some age groups), but then continued to the end of the analytical period. Prevalence of diabetes, hypertension and obesity among patients testing positive also declined—two for most age groups (reductions of up to 10 percentage points for diabetes, 12 percentage points for hypertension and 19 percentage points for obesity). ConclusionData suggest that the decrease in COVID-19 fatality rate is at least partially explained by a change in the profile of those contracting the disease, that is, a falling proportion of individuals with comorbidities across all age groups.

This measure caused significant adverse consequences for hospitalized patients. Volunteers’ intervention was an alternative but could also lead to cross transmission events. Aims in order to secure their intervention with patients, we implemented an infection control training to evaluate and to improve the knowledge of volunteers about infection control measures. Method We performed a before-after study in a group of five tertiary referral teaching hospitals in the suburbs of Paris. A total of 226 volunteers from three groups (religious representatives, civilian volunteers and users’ representatives) were included. Basic theoretical and practical knowledge about infection control, hand hygiene, and glove and mask use were evaluated just before and immediately after a three-hour training program. The contribution of the characteristics of the volunteers to the results was studied. Findings The initial conformity rate for theoretical and practical infection control measures ranged from 53% to 68%, depending on the participants’ activity status and education level. Some critical shortcomings in hand hygiene as well as mask and glove wearing putatively endangered the patients and volunteers. Surprisingly, serious gaps were also identified among volunteers who experienced care activities. Regardless of their origin, the program significantly improved both their theoretical and practical knowledge (p
