Concerns of Health Care Professionals Managing non-COVID Patients during The COVID-19 Pandemic: A Descriptive Cross- Sectional Study.

CONTEXT: The coronavirus pandemic has put an unprecedented burden on the health-care workers who are the cornerstone of the work system, preparing to mitigate its effects. Due to the lack of protective equipments, guidelines for managing patients, or proper training and education regarding the same, health care professionals (HCPs) working in non-COVID areas may face even greater problems than those working in COVID areas of a hospital. Our aim was to find out the concerns of HCPs working in non-COVID areas. SUBJECTS AND METHODS: After obtaining institutional ethics approval, a descriptive cross-sectional study was planned. An online Google-based questionnaire was rolled out to all doctors through various social media platforms who were dealing with COVID-negative patients. RESULTS: We received a total of 110 responses. 84.5% of participants were concerned about the risk of infection to self and family, 67.3% were concerned by the disruption of their daily activities. 56.4% of HCPs were disturbed by the lack of any concrete protocol for patient management. Less staff availability, delay in discharging duties toward their patients, and increased workload were other concerns. More than half of the doctors received N-95 masks whenever required and were trained in donning and doffing of Personal protective equipment. Sixty-eight percemt of our respondents labeled their current quality of life as stressful. CONCLUSION: It is the need of the hour to develop a comprehensive strategy focussing on the above challenges that HCPs working in non-COVID areas are facing. This will go a long way in not only providing holistic care to the patients but also in controlling this pandemic.

Concerns of Health-care Professionals Managing COVID Patients under Institutional Isolation during COVID-19 Pandemic in India: A Descriptive Cross-sectional Study.

OBJECTIVE: Health-care professionals (HCPs) are the frontline warriors in the time of this uncertain and unpredictable crisis of COVID. They face many challenges while caring for these patients, yet they are expected to cope with it and deliver their duties for the betterment of humankind. Our primary aim was to identify and assess the concerns of HCPs working in COVID area in a tertiary institutional isolation center. METHODOLOGY: An online Google-based questionnaire survey was distributed through various social media platforms after approval of the institutional review board to a total of 100 HCPs who were treating and managing COVID-positive patients. RESULTS: Of 100 responses, 72% were concerned about the risk of infection to self and family, while 46% reported disruption of their daily activities at a personal level. At the institutional level, 17% were concerned about inadequate personal protective equipment-related challenges. 20% had inadequate knowledge and training about COVID. 16% of participants were anxious all the time, 11% feared all the time, and 12% had stress all the time while treating COVID patients. Connectedness and communication with family and friends, word of appreciation, music, and TV were few strategies to cope up with these challenges. CONCLUSION: There is a need to identify and address the concerns and challenges faced by HCPs and to develop a comprehensive strategy and guideline to provide a holistic care and to ensure their security in the workplace.

Factors of sexual quality of life in gynaecological cancers: a systematic literature review.

BACKGROUND: The impact of cancer diagnosis and treatment on sexual quality of life (SQoL) is a well-established survivorship issue for gynaecological cancer survivors (GCS), yet little is known on how to intervene. PURPOSE: The aim of this systematic review was to identify the factors explaining the variability in SQoL for GCS. METHODS: We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework and the software Covidence. Electronic databases Scopus, Web of Science, PUBMED and CINAHL were searched for original research on GCS published between 2002 and 2018. We performed a two-stage screening process against selection criteria and quality assessment of individual studies. The Salutogenic Theory and the PRECEDE-PROCEED model were used as theoretical frameworks to identify and categorise factors. RESULTS: The initial search yielded 3,505 articles resulting in a total of 46 studies used to examine the association between factors of SQoL and gynaecological cancers. Our findings suggested that SQoL varies across subgroups based on age, menopausal status, relationship status, and treatment modality. Protective factors included clinicians' knowledge and confidence, preventive medical approach, risk and needs assessment, patient-clinician communication, relationship quality, psychosocial support, symptom management, accessibility of psychosexual care, and self-efficacy in the rediscovery of sexuality. CONCLUSION: Despite the high incidence and long-term impact of sexual health issues on quality of life, supportive care needs are not being met. A better understanding of the evidence base around the factors of SQoL can help health professionals take steps to protect and improve SQoL in GCS.

Coronavirus Disease 2019 in Children.

Since its appearance in Wuhan in mid-December 2019, acute respiratory syndrome coronavirus 2 (SARS-CoV-2) related 19 coronavirus disease (COVID-19) has spread dramatically worldwide. It soon became apparent that the incidence of pediatric COVID-19 was much lower than the adult form. Morbidity in children is characterized by a variable clinical presentation and course. Symptoms are similar to those of other acute respiratory viral infections, the upper airways being more affected than the lower airways. Thus far, over 90% of children who tested positive for the virus presented mild or moderate symptoms and signs. Most children were asymptomatic, and only a few cases were severe, unlike in the adult population. Deaths have been rare and occurred mainly in children with underlying morbidity. Factors as reduced angiotensin-converting enzyme receptor expression, increased activation of the interferon-related innate immune response, and trained immunity have been implicated in the relative resistance to COVID-19 in children, however the underlying pathogenesis and mechanism of action remain to be established. While at the pandemic outbreak, mild respiratory manifestations were the most frequently described symptoms in children, subsequent reports suggested that the clinical course of COVID-19 is more complex than initially thought. Thanks to the experience acquired in adults, the diagnosis of pediatric SARS-CoV-2 infection has improved with time. Data on the treatment of children are sparse, however, several antiviral trials are ongoing. The purpose of this narrative review is to summarize current understanding of pediatric SARS-CoV-2 infection and provide more accurate information for healthcare workers and improve the care of patients.

How to deliver aerosolized medications through high flow nasal cannula safely and effectively in the era of COVID-19 and beyond: A narrative review.

BACKGROUND: The treatments of COVID-19 involve some degree of uncertainty. Current evidence also shows mixed findings with regards to bioaerosol dispersion and airborne transmission of COVID-19 during high flow nasal cannula (HFNC) therapy. While coping with this global pandemic created hot debates on the use of HFNC, it is important to bring detached opinions and current evidence to the attention of health care professionals (HCPs) who may need to use HFNC in patients with COVID-19. AIM: The purpose of this paper is to provide a framework on the selection, placement, and use of nebulizers as well as HFNC prongs, gas flow, and delivery technique via HFNC to help clinicians deliver aerosolized medications through HFNC safely and effectively in the era of COVID-19 and beyond. METHODS: We searched PubMed, Medline, CINAHL, and Science Direct to identify studies on aerosol drug delivery through HFNC using the following keywords: ("aerosols," OR "nebulizers") AND ("high flow nasal cannula" OR "high flow oxygen therapy" OR "HFNC") AND ("COVID-19," OR "SARS-CoV-2"). Twenty-eight articles including in vitro studies, randomized clinical trials, scintigraphy studies, review articles, prospective and retrospective research were included in this review. DISCUSSION AND RESULTS: It is not clear if the findings of the previous studies on bacterial contamination could be applied to viral transmission because they do not provide data that could be extrapolated to the risk of SARS-CoV-2 transmission. In the face of the unknown risk with the transmission of COVID-19 during HFNC therapy, the benefits of HFNC must be weighed against the risk of infection to HCPs and other patients. Due to the limited number of ventilators available in hospitals and the confirmed effectiveness of HFNC in treating hypoxemic respiratory failure, HFNC may prevent early intubation, and prolonged intensive care unit stays in patients with COVID-19. CONCLUSION: Clinicians should review the magnitude of this risk based on current evidence and use the suggested strategies of this paper for safe and effective delivery of aerosolized medications through HFNC in the era of COVID-19 and beyond.

Hospital-Based Health Care Worker Perceptions of Personal Risk Related to COVID-19.

BACKGROUND: Health care workers treating Coronavirus disease 2019 (COVID-19) patients face significant stressors such as caring for critically ill and dying patients, physically demanding care requiring new degrees of personal protective equipment use, risk of contracting the disease, and putting loved ones at risk. This study investigates the stress impact from COVID-19 exposure and how nurses and medical providers (eg, physicians, nurse practitioners, physician assistants) experience these challenges differently. METHODS: An electronic, self-administered questionnaire was sent to all hospital staff over 6 weeks surveying exposure to COVID-19 patients and degree of stress caused by this exposure. Responses from medical providers and nurses were analyzed for significant contributors to stress levels, as well as comparing responses from medical providers versus nurses. RESULTS: Stress levels from increased risk of disease contraction while on the job, fear of transmitting it to family or friends, and the resulting social stigma were highest in medical staff during the COVID-19 pandemic. Compared with medical providers, nurses had nearly 4 times the odds of considering job resignation due to COVID-19. However, most health care workers (77.4% of medical providers and 52.9% of nurses) strongly agreed or agreed with the statements indicating high levels of altruism in their desire to treat COVID-19 patients. CONCLUSION: The significant stress burden placed on nurses likely contributes to increased thoughts of job resignation. However, health care providers displayed high levels of altruism during this time of extreme crisis, despite their personal risks of caring for COVID-19 patients.

Early and Mid-Term Implications of the COVID-19 Pandemic on the Physical, Behavioral and Mental Health of Healthcare Professionals: The CoPE-HCP Study Protocol.

INTRODUCTION: The COVID-19 pandemic has led to unprecedented strain to healthcare systems worldwide and posed unique challenges to the healthcare professionals (HCPs) and the general public. OBJECTIVES: The aim of this study is to evaluate the impact of COVID-19 on the mental health, behavioral, and physical wellbeing of HCPs in the early and mid-term periods of the pandemic in comparison to non-HCPs. Thus, facilitating and guiding optimum planning and delivery of support to HCPs. METHODS AND ANALYSIS: An observational cross-sectional survey and cohort study aiming to enroll over 1050 participants (minimum, 800 HCPs and 250 controls). Study questionnaires will be completed at baseline and after 6-weeks and 4-months. Recruitment initiated July 2020. The study was designed in London, United Kingdom, but open to participants worldwide. Baseline: Questionnaires comprising of validated self-administered screening tools for depression, anxiety, sleep-related issues, wellbeing, and burnout. The questionnaires also explore changes in behavior and physical wellbeing of the participants. In addition, associations of these mental health and behavioral factors with work-related factors and support will be explored. Six-weeks and 4-months follow-up: Follow-up questionnaires will assess change in symptoms of anxiety and depression, sleep disorders, use of alcohol and other substances, behavioral or interpersonal relationship changes. Physical wellbeing will be assessed through the presence of suspected or confirmed COVID-19 infection and absence from work. We will also evaluate the impact of variable provision of personal protection equipment (supply and training), extended working hours, and concern for the wellbeing of family members, anxiety levels, and evidence of burnout. STATISTICAL CONSIDERATIONS: The study has 80% power to detect a 10% difference of combined depression and/or anxiety symptoms between the groups using two-sided type 1 error at 0.05 at baseline. Assuming that only 50% of these HCPs agree to be a part of a cohort survey, we will have 80% power to detect around 12% difference in the two groups in reported physical symptoms (20% vs. 32.3%), or prevalence of depression and/or anxiety at the end of the study. ETHICS: The study was approved by the Cambridge East, Research Ethics Committee (20/EE/0166). TRIAL REGISTRATION NUMBER: ClinicalTrials.gov, NCT04433260.

Gastrointestinal manifestations of COVID-19.

Gastrointestinal (GI) symptoms are seen in patients with COVID-19. The prevalence could be as high as 50%, but most studies show ranges from 16% to 33%. Presenting with GI symptoms increases the risk of testing positive for SARs-CoV-2. Approximately 50% of patients with COVID-19 have detectable virus in their stool. Having GI symptoms has been associated with more severe disease. Management of GI symptoms is mainly supportive. Healthcare providers should be aware of the GI manifestations of COVID-19 and perform SARS-CoV-2 testing for patients presenting with digestive changes, especially in those with respiratory symptoms.

Risk Factors Associated with COVID-19 Infected Healthcare Workers in Muscat Governorate, Oman.

INTRODUCTION: Coronavirus disease 2019 (COVID-19) has spread rapidly worldwide, causing a global public health crisis. Healthcare workers (HCWs) are vulnerable due to their role in the management of COVID-19 infected patients. As of June 2020, a total of 847 HCWs in Oman had reportedly contracted COVID-19, with an incidence rate of 1.47%. This study therefore aimed to identify factors associated with COVID-19 infection among HCWs in Muscat Governorate, Oman, as well as to evaluate adherence to infection prevention and control (IPC) measures. METHODS: This cross-sectional study involved cases of laboratory-confirmed COVID-19 infection among HCWs working under the Directorate General of Health Services of Muscat Governorate, Ministry of Health, between February and June 2020. Data regarding the participants' sociodemographic characteristics, risk factors, pre-existing medical conditions, and adherence to IPC measures were collected using a self-administered questionnaire distributed via a web-based mobile application. RESULTS: A total of 126 HCWs with confirmed COVID-19 infection participated in the study. Of these, 72.2% were female, 53.2% worked in primary care facilities, and 61.1% were medical doctors or nurses. Only 18.1% were over 45 years of age and 30.2% had pre-existing medical conditions. While 29.4% had never received IPC training, the majority followed recommended hand hygiene practice (96.8%) and social distancing protocols (93.7%) and wore protective facemasks for routine patient care (96.9%). CONCLUSION: While the majority of HCWs followed crucial IPC measures, one-third had never received specific IPC training or faced restrictions on PPE use. HCWs, including those in housekeeping and administrative functions are recommended to undergo rigorous IPC training. In addition, high-risk HCWs could be assigned duties away from active COVID 19 cases. It is recommended to restructure health facilities for better adherence to IPC standards.

Challenges and concerns of patients with congenital bleeding disorders affected by coronavirus disease 2019.

Coronavirus disease 2019 (COVID-19) is a new medical challenge for all individuals, especially for those with underlying disorders, such as congenital bleeding disorders (CBDs). Therefore, the pandemic might significantly change the behaviour of patients with CBDs and results in some challenges. In the present study, we assessed the main challenges of COVID-19 infection to patients with CBDs. Data were collected from medical files and interviews of patients with CBDs who had COVID-19 infection. Follow-ups were performed on patients who had active severe acute respiratory syndrome coronavirus 2 infection between April and October 2020. All patients were interviewed by an expert in order to collect the pertinent data. Some questions were about patients' preventive behaviors and feelings prior to infection, and some were about the consequences of infection on patients' replacement therapy and bleeding management. Among 25 patients, infection and death of loved ones (n: 7, 28%), and their own (n: 5, 20%) or family members' (n: 1, 4%) infection, and the resulting economic burden (n: 2, 8%) were main concerns. Six patients experienced depression during the pandemic. The pandemic caused all severely affected patients but one (n: 11, 92%) to abandon replacement therapy. However, two received on-demand therapy after exacerbation of their bleeding. Only one (25%) of four patients on prophylaxis received in-home therapy, whereas the others (75%) abandoned prophylaxis. It seems that COVID-19 infection has great consequences on the lives of patients with CBDs, causing some to take dangerous actions, such as abandonment of their treatment. Healthcare systems, and healthcare providers, should have an appropriate strategy for management of patients with CBDs that prevents infection and provides timely replacement therapy.

Understanding Drivers of Coronavirus Disease 2019 Vaccine Hesitancy Among Blacks.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has disproportionately affected communities of color, with black persons experiencing the highest rates of disease severity and mortality. A vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has the potential to reduce the race mortality gap from COVID-19; however, hesitancy toward the vaccine in the black community threatens vaccine uptake. METHODS: We conducted focus groups with black barbershop and salon owners living in zip codes of elevated COVID-19 prevalence to assess their attitudes, beliefs, and norms around a COVID-19 vaccine. We used a modified grounded theory approach to analyze the transcripts. RESULTS: We completed 4 focus groups (N = 24 participants) in July and August 2020. Participants were an average age of 46 years, and 89% were black non-Hispanic. Hesitancy against the COVID-19 vaccine was high due to mistrust in the medical establishment, concerns with the accelerated timeline for vaccine development, limited data on short- and long-term side effects, and the political environment promoting racial injustice. Some participants were willing to consider the vaccine once the safety profile is robust and reassuring. Receiving a recommendation to take the vaccine from a trusted healthcare provider served as a facilitator. Health beliefs identified were similar to concerns around other vaccines and included the fear of getting the infection with vaccination and preferring to improve one's baseline physical health through alternative therapies. CONCLUSIONS: We found that hesitancy of receiving the COVID-19 vaccine was high; however, provider recommendation and transparency around the safety profile might help reduce this hesitancy.

The association between witnessing patient death and mental health outcomes in frontline COVID-19 healthcare workers.

BACKGROUND: Healthcare workers (HCW) treating coronavirus disease 2019 (COVID-19) patients face high levels of psychological stress. We aimed to compare mental health outcomes, risk and protective factors for posttraumatic stress symptoms (PTSS), probable depression, and anxiety between HCW working in COVID-19 and non-COVID-19 wards. METHODS: A self-report survey, administered in a large tertiary hospital in Israel during the peak of the COVID-19 outbreak was completed by 828 HCW (42.2% physicians, 57.8% nurses. Patient-Reported Outcomes Measurement Information System; the Patient Health Questionnaire-9; the Primary Care-Post Traumatic Stress Disorder Screen for DSM-5 (PC-PTSD-5) were used for assessing anxiety, depression, and PTSS, respectively. Pandemic-related stress factors, negative experiences, and potential protective factors were also assessed. RESULTS: Median PC-PTSD scores differed significantly between study teams (χ2 [5] = 17.24; p = .004). Prevalence of probable depression and anxiety were similar in both groups. Risk factors for mental health outcomes included mental exhaustion, anxiety about being infected and infecting family. Overall, higher proportion of the COVID-19 team witnessed patient deaths as compared to the non-COVID-19 team (50.2% vs. 24.7%). Witnessing patient death at the COVID-19 wards was associated with a four-fold increased likelihood of PTSS (odds ratio [OR] = 3.97; 95% confidence interval [CI], 1.58-9.99; p = .0007), compared with the non-COVID-19 wards (OR 0.91; 95% CI, 0.51-1.61; p = .43). CONCLUSIONS: Witnessing patient death appears to be a risk factor for PTSS unique to HCW directly engaged in treating patients with COVID-19. Our findings suggest that helping HCW cope with COVID-19 related deaths might reduce their risk of posttraumatic stress.

Covid-19 Automated Diagnosis and Risk Assessment through Metabolomics and Machine Learning.

COVID-19 is still placing a heavy health and financial burden worldwide. Impairment in patient screening and risk management plays a fundamental role on how governments and authorities are directing resources, planning reopening, as well as sanitary countermeasures, especially in regions where poverty is a major component in the equation. An efficient diagnostic method must be highly accurate, while having a cost-effective profile. We combined a machine learning-based algorithm with mass spectrometry to create an expeditious platform that discriminate COVID-19 in plasma samples within minutes, while also providing tools for risk assessment, to assist healthcare professionals in patient management and decision-making. A cross-sectional study enrolled 815 patients (442 COVID-19, 350 controls and 23 COVID-19 suspicious) from three Brazilian epicenters from April to July 2020. We were able to elect and identify 19 molecules related to the disease's pathophysiology and several discriminating features to patient's health-related outcomes. The method applied for COVID-19 diagnosis showed specificity >96% and sensitivity >83%, and specificity >80% and sensitivity >85% during risk assessment, both from blinded data. Our method introduced a new approach for COVID-19 screening, providing the indirect detection of infection through metabolites and contextualizing the findings with the disease's pathophysiology. The pairwise analysis of biomarkers brought robustness to the model developed using machine learning algorithms, transforming this screening approach in a tool with great potential for real-world application.

BCG vaccination in health care providers and the protection against COVID-19.

A number of coronavirus disease 2019 (COVID-19) vaccine candidates have shown promising results, but substantial uncertainty remains regarding their effectiveness and global rollout. Boosting innate immunity with bacillus Calmette Guérin (BCG) or other live attenuated vaccines may also play a role in the fight against the COVID-19 pandemic. BCG has long been known for its nonspecific beneficial effects that are most likely explained by epigenetic and metabolic reprogramming of innate immune cells, termed trained immunity. In this issue of the JCI, Rivas et al. add to these arguments by showing that BCG-vaccinated health care providers from a Los Angeles health care organization had lower rates of COVID-19 diagnoses and seropositivity compared with unvaccinated individuals. Prospective clinical trials are thus warranted to explore the effects of BCG vaccination in COVID-19. We posit that beyond COVID-19, vaccines such as BCG that elicit trained immunity may mitigate the impact of emerging pathogens in future pandemics.

Perioperative challenges in managing a patient with COVID-19 undergoing debridement for massive scalp myiasis.

A young man presented to our centre needing an urgent debridement of his postcraniotomy wound due to massive myiasis during the COVID-19 pandemic in October 2020. Prior to the surgery, his nasopharyngeal swab real-time PCR test result was unknown. One day later, it returned as SARS-CoV-2 positive. All healthcare workers who were involved in the patient management avoided cross infection as they wore appropriate personal protective equipment. This article depicts the importance of adequate preparations when handling potentially infectious patients and the perioperative issues associated with it.

Self-Collected Saline Gargle Samples as an Alternative to Health Care Worker-Collected Nasopharyngeal Swabs for COVID-19 Diagnosis in Outpatients.

We assessed the performance, stability, and user acceptability of swab-independent self-collected saliva and saline mouth rinse/gargle sample types for the molecular detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in adults and school-aged children. Outpatients who had recently been diagnosed with COVID-19 or were presenting with suspected COVID-19 were asked to have a nasopharyngeal (NP) swab collected and provide at least one self-collected sample type. Participants were also asked about sample acceptability using a five-point Likert scale. For those previously diagnosed with COVID-19, all samples underwent real-time PCR testing using a lab-developed assay, and the majority were also tested using an FDA-authorized assay. For those presenting with suspected COVID-19, only those with a positive nasopharyngeal swab sample went on to have other samples tested. Saline mouth rinse/gargle and saliva samples were tested daily at time zero, day 1, and day 2 to assess nucleic acid stability at room temperature. Fifty participants (aged 4 to 71 years) were included; of these, 40 had at least one positive sample and were included in the primary sample yield analysis. Saline mouth rinse/gargle samples had a sensitivity of 98% (39/40), while saliva samples had a sensitivity of 79% (26/33). Both saline mouth rinse/gargle and saliva samples showed stable viral RNA detection after 2 days of room temperature storage. Mouth rinse/gargle samples had the highest (mean, 4.9) and health care worker (HCW)-collected NP swabs had the lowest acceptability scores (mean, 3.1). In conclusion, saline mouth rinse/gargle samples demonstrated higher combined user acceptability ratings and analytical performance than saliva and HCW-collected NP swabs. This sample type is a promising swab-independent option, particularly for outpatient self-collection in adults and school-aged children.

Evaluation of a home-based 7-day infection control strategy for healthcare workers following high-risk exposure to severe acute respiratory coronavirus virus 2 (SARS-CoV-2): A cohort study.

OBJECTIVE: Evidence-based infection control strategies are needed for healthcare workers (HCWs) following high-risk exposure to severe acute respiratory coronavirus virus 2 (SARS-CoV-2). In this study, we evaluated the negative predictive value (NPV) of a home-based 7-day infection control strategy. METHODS: HCWs advised by their infection control or occupational health officer to self-isolate due to a high-risk SARS-CoV-2 exposure were enrolled between May and October 2020. The strategy consisted of symptom-triggered nasopharyngeal SARS-CoV-2 RNA testing from day 0 to day 7 after exposure and standardized home-based nasopharyngeal swab and saliva testing on day 7. The NPV of this strategy was calculated for (1) clinical coronavirus disease 2019 (COVID-19) diagnosis from day 8-14 after exposure, and for (2) asymptomatic SARS-CoV-2 detected by standardized nasopharyngeal swab and saliva specimens collected at days 9, 10, and 14 after exposure. Interim results are reported in the context of a second wave threatening this essential workforce. RESULTS: Among 30 HCWs enrolled, the mean age was 31 years (SD, ±9), and 24 (80%) were female. Moreover, 3 were diagnosed with COVID-19 by day 14 after exposure (secondary attack rate, 10.0%), and all cases were detected using the 7-day infection control strategy: the NPV for subsequent clinical COVID-19 or asymptomatic SARS-CoV-2 detection by day 14 was 100.0% (95% CI, 93.1%-100.0%). CONCLUSIONS: Among HCWs with high-risk exposure to SARS-CoV-2, a home-based 7-day infection control strategy may have a high NPV for subsequent COVID-19 and asymptomatic SARS-CoV-2 detection. Ongoing data collection and data sharing are needed to improve the precision of the estimated NPV, and here we report interim results to inform infection control strategies in light of a second wave threatening this essential workforce.

Stress and Anxiety among Healthcare Workers Associated with COVID-19 Pandemic in Russia.

BACKGROUND: Mental health of medical workers treating patients with COVID-19 is an issue of increasing concern worldwide. The available data on stress and anxiety symptoms among healthcare workers during the COVID-19 are relatively limited and have not been evaluated in Russia yet. SUBJECTS AND METHODS: The cross-sectional anonymous survey included 1,090 healthcare workers. Stress and anxiety symptoms were assessed using Stress and Anxiety to Viral Epidemics - 9 (SAVE-9) and Generalized Anxiety Disorder - 7 (GAD-7) scales. Logistic regression, Kaiser-Meyer-Olkin two component factor model, Cronbach's alpha and ROC-analysis were performed to determine the influence of different variables, internal structure and consistency, sensitivity and specificity of SAVE-9 compared with GAD-7. RESULTS: The median scores on the GAD-7 and SAVE-9 were 5 and 14, respectively. 535 (49.1%) respondents had moderate and 239 (21.9%) had severe anxiety according to SAVE-9. 134 participants (12.3%) had severe anxiety, 144 (13.2%) had moderate according to GAD-7. The component model revealed two-factor structure of SAVE-9: "anxiety and somatic concern" and "social stress". Female gender (OR - 0.98, p=0.04) and younger age (OR - 0.65, p=0.04) were associated with higher level of anxiety according to regression model. The total score of SAVE-9 with a high degree of confidence predicted the GAD-7 value in comparative ROC analysis. CONCLUSIONS: Healthcare workers in Russia reported high rates of stress and anxiety. The Russian version of the SAVE-9 displayed a good ratio of sensitivity to specificity compared with GAD-7 and can be recommended as a screening instrument for detection of stress and anxiety in healthcare workers.

Seroprevalence of SARS-CoV-2 IgG specific antibodies among healthcare workers in the Northern Metropolitan Area of Barcelona, Spain, after the first pandemic wave.

BACKGROUND: The rapid spread of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) around the world has caused a global pandemic, infecting millions of individuals, with an unprecedented impact in health care systems worldwide. Healthcare workers are one of the risk groups that need to be well protected, due to their strategic role in patient management, presently and in prevention of healthcare needs for future outbreaks. Here, we present the results of the first SARS-CoV-2 seroprevalence study in the Northern Metropolitan Area of Barcelona, Spain. METHODS: IgG SARS-CoV-2 antibodies were analyzed in serum samples from 7563 healthcare workers of the Northern Metropolitan Area of Barcelona. Samples were collected after the first pandemic wave (from May 4th to May 22nd, 2020) and were analyzed by automated chemiluminescence assays. All samples were tested for IgG anti-S1/S2. Participant samples with negative or equivocal results but with analytical signals above the limit of detection and/or previously confirmed COVID-19 diagnosis were also tested for IgG anti-Nucleocapsid. RESULTS: A total of 779 of 7563 (10.3%) healthcare workers were positive for anti-SARS-CoV-2 IgG (specific for either S1/S2 or N antigens). No significant differences were observed between those working at primary care or at the reference hospital. Interestingly, among 341 participants with a confirmed COVID-19 diagnosis, 36 (10.55%) tested negative for SARS-CoV-2 IgG (both S1/S2 and recombinant N antigen). CONCLUSION: Seroprevalence of anti-SARS-CoV-2 IgG in the healthcare workers of the North Metropolitan Area of Barcelona was higher than in the general population in the same geographical area. Safety measures have to be stressed in order to protect these essential workers from future pandemic waves.
