[Cross-sectional study on the use of masks among occupational groups with high-risk positions for overseas import and pollution transmission].

Objective: To investigate the wearing of masks and the knowledge of masks among high-risk positions for overseas import and pollution transmission. Methods: From May 14 to 17, 2022, a convenient sampling method was used to conduct an online survey among 963 workers in high-risk positions for overseas import and pollution transmission in Beijing. The behaviors of individual use and wearing masks, the distribution and supervision of the unit, the knowledge of personal mask protection and the subjective feelings of wearing masks were analyzed. The χ(2) test and logistic regression model were used to analyze the influencing factors of the correct selection of masks. Results: The majority of the workers in high-risk positions for overseas import and pollution transmission were male (86.0%, 828/963), age concentration in 18-44 years old (68.2%, 657/963), and the majority of them had college or bachelor degrees (49.4%, 476/963). 79.4%(765/963) of the workers chose the right type of masks, female, 45-59 years old and high school education or above were the risk factors for correct selection of masks (P <0.05). Workers had good behaviors such as wearing/removing masks, but only 10.5% (101/963) could correctly rank the protective effect of different masks. 98.4% (948/963) of the workers believed that their work units had provided masks to their employees, and 99.1% (954/963) and 98.2%(946/963) of them had organized training and supervision on the use of masks, respectively. 47.4%(456/963) of the workers were uncomfortable while wearing masks. Conclusion: The overall selection and use of masks among occupational groups in high-risk positions for overseas import and pollution transmission in China need to be further standardized. It is necessary to strengthen supervision and inspection on the use of masks among occupational groups, and take improvement measures to improve the comfort of wearing masks.

Delivery of menopause care during a pandemic: an evaluation of patient satisfaction with telephone visits.

OBJECTIVE: We aimed to evaluate patient satisfaction with telephone appointments during the first wave of the COVID-19 pandemic, determine visit type preference (in-person vs telephone), and predictors of those preferences. METHODS: In this cross-sectional study, patient visits during the first wave of COVID-19 (March 20 to July 15, 2020) were characterized (in-person vs telephone) in a single provider's weekly menopause clinic in Toronto, Canada. Patients attending telephone appointments were asked to complete a modified Telemedicine Satisfaction Questionnaire with 5-point Likert-scale responses. Demographic information was collected along with the patient-reported cost to attend an in-person appointment (monetary, travel time, and time away from work). Of those who experienced both visit types, preference was evaluated and bivariate analysis was performed identifying factors associated with visit type preference and included in a multivariable binary logistic regression model. RESULTS: During the first wave of the COVID-19 pandemic, 214 women had 246 visits, attending mostly by telephone (221/246, 90%). Mean Telemedicine Satisfaction Questionnaire composite score was 4.23 ±â€Š0.72. Of those who attended a prepandemic in-person appointment (118/139, 85%), a minority (24/118, 20%) preferred in-person visits. Those favoring in-person were more likely to commute less than 30 minutes (OR 3.78, 95% CI 1.16-12.29, P = 0.027), require less than 2 hours away from work (OR 4.05, 95% CI 1.07-15.4, P = 0.04), and spend less than $10 to attend (OR 3.67, 95% CI 1.1-12.26, P = 0.035). CONCLUSIONS: Menopause clinic telephone appointments had high patient satisfaction, with most preferring this visit type, although in-person visits are preferred among a minority of women.

Neurologic manifestations associated with COVID-19: a multicentre registry.

OBJECTIVES: To provide an overview of the spectrum, characteristics and outcomes of neurologic manifestations associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. METHODS: We conducted a single-centre retrospective study during the French coronavirus disease 2019 (COVID-19) epidemic in March-April 2020. All COVID-19 patients with de novo neurologic manifestations were eligible. RESULTS: We included 222 COVID-19 patients with neurologic manifestations from 46 centres in France. Median (interquartile range, IQR) age was 65 (53-72) years and 136 patients (61.3%) were male. COVID-19 was severe or critical in 102 patients (45.2%). The most common neurologic diseases were COVID-19-associated encephalopathy (67/222, 30.2%), acute ischaemic cerebrovascular syndrome (57/222, 25.7%), encephalitis (21/222, 9.5%) and Guillain-Barré syndrome (15/222, 6.8%). Neurologic manifestations appeared after the first COVID-19 symptoms with a median (IQR) delay of 6 (3-8) days in COVID-19-associated encephalopathy, 7 (5-10) days in encephalitis, 12 (7-18) days in acute ischaemic cerebrovascular syndrome and 18 (15-28) days in Guillain-Barré syndrome. Brain imaging was performed in 192 patients (86.5%), including 157 magnetic resonance imaging (70.7%). Among patients with acute ischaemic cerebrovascular syndrome, 13 (22.8%) of 57 had multiterritory ischaemic strokes, with large vessel thrombosis in 16 (28.1%) of 57. Brain magnetic resonance imaging of encephalitis patients showed heterogeneous acute nonvascular lesions in 14 (66.7%) of 21. Cerebrospinal fluid of 97 patients (43.7%) was analysed, with pleocytosis found in 18 patients (18.6%) and a positive SARS-CoV-2 PCR result in two patients with encephalitis. The median (IQR) follow-up was 24 (17-34) days with a high short-term mortality rate (28/222, 12.6%). CONCLUSIONS: Clinical spectrum and outcomes of neurologic manifestations associated with SARS-CoV-2 infection were broad and heterogeneous, suggesting different underlying pathogenic processes.

[Evidence of the validity of a Brazilian version of the Fear of COVID-19 Scale]. / Evidências de validade de uma versão brasileira da Fear of COVID-19 Scale.

This study sought to analyze the evidence of the validity of a Brazilian version of the Fear of COVID-19 Scale (FCV-19S), based on indicators relating to: (1) the internal structure; (2) the internal consistency; (3) the relation with external variables; and (4) the content. The instrument was culturally adapted, focusing on semantic and specifically Brazilian linguistic aspects. The Brazilian version of the FCV-19S was then applied, in a virtual environment, to 211 participants (72.98% female) with an average age of 37.07 years (SD=13.03), together with the Self-Perception Questionnaire on Mental Health in Pandemics and the Sociodemographic and Functional Questionnaire. The confirmatory factor analysis revealed one-dimensionality. The internal consistency indices obtained (Cronbach's alpha =0.921; McDonald's omega =0.926) can be considered high. The correlation between fear and obsessive thinking of the disease, generalized anxiety, generalized stress, phobic-avoidant behavior and bereavement due to the pandemic was found to be statistically significant. Evidence of the validity related to content, derived from a qualitative approach, were satisfactory. The conclusion drawn is that the Brazilian version of the FCV-19S proved to be adequate regarding the evidence of the expected validity.

O presente estudo teve como objetivo analisar evidências de validade de uma versão brasileira da Fear of COVID-19 Scale (FCV-19S), com base em indicadores concernentes: (1) à estrutura interna; (2) à consistência interna; (3) à relação com variáveis externas; e (4) ao conteúdo. Procedeu-se a adaptação cultural do instrumento, com foco em aspectos semânticos e linguísticos próprios do Brasil. A seguir, esta versão brasileira da FCV-19S foi aplicada, em um ambiente virtual, em 211 participantes (72,98% do sexo feminino), com idade média de 37,07 anos (DP=13,03), juntamente com o Questionário de Autopercepção de Saúde Mental em Pandemia e o Questionário Sociodemográfico e Funcional. A análise fatorial confirmatória atestou unidimensionalidade. Os índices de consistência interna obtidos (alfa de Cronbach =0,921; ômega de McDonald =0,926) podem ser considerados elevados. Constatou-se correlação estatisticamente significativa entre medo e pensamento obsessivo, ansiedade generalizada, estresse generalizado, comportamento fóbico-evitativo e vivência de luto pela pandemia. As evidências de validade relativas ao conteúdo, oriundas de uma abordagem qualitativa, foram satisfatórias. Conclui-se que esta versão brasileira da FCV-19S mostrou-se adequada quanto às evidências de validade contempladas.

Death following pulmonary complications of surgery before and during the SARS-CoV-2 pandemic.

BACKGROUND: This study aimed to determine the impact of pulmonary complications on death after surgery both before and during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. METHODS: This was a patient-level, comparative analysis of two, international prospective cohort studies: one before the pandemic (January-October 2019) and the second during the SARS-CoV-2 pandemic (local emergence of COVID-19 up to 19 April 2020). Both included patients undergoing elective resection of an intra-abdominal cancer with curative intent across five surgical oncology disciplines. Patient selection and rates of 30-day postoperative pulmonary complications were compared. The primary outcome was 30-day postoperative mortality. Mediation analysis using a natural-effects model was used to estimate the proportion of deaths during the pandemic attributable to SARS-CoV-2 infection. RESULTS: This study included 7402 patients from 50 countries; 3031 (40.9 per cent) underwent surgery before and 4371 (59.1 per cent) during the pandemic. Overall, 4.3 per cent (187 of 4371) developed postoperative SARS-CoV-2 in the pandemic cohort. The pulmonary complication rate was similar (7.1 per cent (216 of 3031) versus 6.3 per cent (274 of 4371); P = 0.158) but the mortality rate was significantly higher (0.7 per cent (20 of 3031) versus 2.0 per cent (87 of 4371); P < 0.001) among patients who had surgery during the pandemic. The adjusted odds of death were higher during than before the pandemic (odds ratio (OR) 2.72, 95 per cent c.i. 1.58 to 4.67; P < 0.001). In mediation analysis, 54.8 per cent of excess postoperative deaths during the pandemic were estimated to be attributable to SARS-CoV-2 (OR 1.73, 1.40 to 2.13; P < 0.001). CONCLUSION: Although providers may have selected patients with a lower risk profile for surgery during the pandemic, this did not mitigate the likelihood of death through SARS-CoV-2 infection. Care providers must act urgently to protect surgical patients from SARS-CoV-2 infection.

This study compared death rates in patients who developed pulmonary complications of surgery before and during the pandemic in two large, international studies. Patients who underwent surgery during the pandemic tended to be younger and fitter. Overall, 4.3 per cent were diagnosed with SARS-CoV-2 infection after surgery in the pandemic cohort. Deaths within 30 days after surgery tripled during the first wave of the pandemic (from 0.7 to 2.0 per cent), whereas the rate of pulmonary complications remained the similar (7.1 to 6.3 per cent). Over half of these excess deaths (54.8 per cent) were estimated to be related to SARS-CoV-2 infection.

Tonic Pupil Following COVID-19.

ABSTRACT: A 37-year-old patient presented to our emergency department with sudden onset decreased vision with a history of being treated for COVID 19 3 weeks earlier. On examination, she was found to have a tonic right pupil, which was confirmed with a dilute pilocarpine test. As tonic pupils are known to be caused by neurotropic viruses and our current understanding of the SARS-CoV-2 is that it does affect the nervous system, we feel that the tonic pupil in our patient may be secondary to COVID 19.

Regulatory CD4+ and CD8+ T cells are negatively correlated with CD4+ /CD8+ T cell ratios in patients acutely infected with SARS-CoV-2.

Regulatory T cell can protect against severe forms of coronaviral infections attributable to host inflammatory responses. But its role in the pathogenesis of COVID-19 is still unclear. In this study, frequencies of total and multiple subsets of lymphocytes in peripheral blood of COVID-19 patients and discharged individuals were analyzed using a multicolor flow cytometry assay. Plasma concentration of IL-10 was measured using a microsphere-based immunoassay kit. Comparing to healthy controls, the frequencies of total lymphocytes and T cells decreased significantly in both acutely infected COVID-19 patients and discharged individuals. The frequencies of total lymphocytes correlated negatively with the frequencies of CD3- CD56+ NK cells. The frequencies of regulatory CD8+ CD25+ T cells correlated with CD4+ /CD8+ T cell ratios positively, while the frequencies of regulatory CD4+ CD25+ CD127- T cells correlated negatively with CD4+ /CD8+ T cell ratios. Ratios of CD4+ /CD8+ T cells increased significantly in patients beyond age of 45 years. And accordingly, the frequencies of regulatory CD8+ CD25+ T cells were also found significantly increased in these patients. Collectively, the results suggest that regulatory CD4+ and CD8+ T cells may play distinct roles in the pathogenesis of COVID-19. Moreover, the data indicate that NK cells might contribute to the COVID-19 associated lymphopenia.

Metformin - a new approach.

Metformin is a widely used biguanide drug recommended as a first-line antidiabetic for type 2 diabetes. Currently, metformin is used not only in the treatment of diabetes but also in other diseases. Some studies have shown that metformin causes weight loss in insulin-sensitive and insulin-resistant overweight and obese patients. Metformin is an effective and safe option for women with gestational diabetes and type 2 diabetes in pregnancy, and it may also increase the ovulation rate in patients with polycystic ovary syndrome (PCOS). Longer survival times have been observed in cancer patients using metformin. Metformin has been shown to significantly correlate with lower mortality in obese or type 2 diabetic women hospitalized for COVID-19. It also has a protective effect on the development and progression of many types of cancer. The mechanisms of action of metformin are complex and still not fully understood. Metformin has been shown to act through both AMP-activated protein kinase (AMPK)-dependent mechanisms and AMPK-independent mechanisms. This paper presents the benefits of using metformin in the treatment of various diseases.

Influenza vaccination in older adults during the COVID-19 pandemic: a population-based study in 133 Brazilian cities. / Vacinação para influenza em idosos na pandemia COVID-19: estudo de base populacional em 133 cidades brasileiras.

Routine immunization during pandemics can be harmed. This study estimated the influenza vaccination coverage in older adults during the COVID-19 through the EPICOVID-19, a population-based study conducted in 133 cities from the 26 Brazilian states and Federal District. We selected 25 census tracts per city, with probability proportional to the tract's size, ten households by census tract, and one random individual interviewed. A total of 8,265 older adults (≥60 years old) were interviewed and asked whether they had been vaccinated against flu in 2020. Vaccination coverage was 82.3% (95% CI: 80.1-84.2) with no difference by gender, age, and region; higher vaccination coverage was observed among the wealthiest (84.7% versus 80.1% in the poorest) and among the more educated (87.3% versus 83.2% less educated); lower coverage among indigenous (56.9% versus > 80% among other ethnic groups). A positive association was identified with the number of comorbidities among men but not among women. Most of the population was vaccinated (97.5%) in the public health system. The private network was chosen mainly in the South by the wealthiest and more educated. Vaccination coverage was seven percentage points lower than the government target (90%), and inequalities should be reversed in future campaigns.

Imunizações de rotina durante pandemias podem ser prejudicadas. Este estudo estimou a cobertura vacinal para influenza em idosos durante a COVID-19 através do EPICOVID-19, inquérito populacional realizado em 133 cidades sentinelas dos 26 estados brasileiros e Distrito Federal. Selecionou-se 25 setores censitários por cidade, amostragem proporcional ao tamanho, dez domicílios por setor e uma pessoa por domicílio, aleatoriamente. O quantitativo de 8.265 idosos (≥ 60 anos) foram entrevistados e responderam se haviam sido vacinados contra gripe em 2020. A cobertura foi 82,3% (IC95% 80,1; 84,2), sem diferenças por sexo, idade ou região. Maiores coberturas ocorreram nos mais ricos (84,7% versus 80,1% nos mais pobres) e nos mais escolarizados (87,3% versus 83,2% nos menos escolarizados). Menor cobertura nos indígenas (56,9% versus coberturas superiores a 80% nos demais grupos étnicos). Houve associação positiva com número de comorbidades entre homens, mas não entre mulheres. A maioria vacinou-se na rede pública (97,5%), sendo a rede privada mais utilizada na região Sul, pelos mais escolarizados e mais ricos. Conclui-se que a cobertura vacinal ficou sete pontos percentuais abaixo da meta governamental (90%), e que desigualdades devem ser revertidas em futuras campanhas.

Clinical analysis of 132 cases COVID-19 from Wuhan.

Numerous cases of pneumonia from a novel coronavirus (SARS-CoV-2) emerged in Wuhan, China during December 2019.We determined the correlations of patient parameters with disease severity in patients with COVID-19.A total of 132 patients from Wuhan Fourth Hospital who had COVID-19 from February 1 to February 29 in 2020 were retrospectively analyzed.Ninety patients had mild disease, 32 had severe disease, and 10 had critical disease. The severe/critical group was older (P < .05), had a higher proportion of males (P < .05), and had a greater mortality rate (0% vs 61.9%, P < .05). The main symptoms were fever (n = 112, 84.8%) and cough (n = 96, 72.7%). Patients were treated with antiviral agents (n = 94, 71.2%), antibiotics (n = 92, 69.7%), glucocorticoids (n = 46, 34.8%), intravenous immunoglobulin (n = 38, 27.3%), and/or traditional Chinese medicine (n = 40, 30.3%). Patients in the severe/critical group received mechanical ventilation (n = 22, 16.7%) or high-flow nasal can-nula oxygen therapy (n = 6, 4.5%). Chest computed tomography (CT) indicated bilateral pneumonia in all patients. Relative to the mild group, the severe/critical group had higher levels of leukocytes, C-reactive protein (CRP), procalcitonin (PCT), D-dimer, B-type natriuretic peptide (BNP), liver enzymes, and myocardial enzymes (P < .05), and decreased levels of lymphocytes and blood oxygen partial pressure (P < .05).The main clinical symptoms of patients from Wuhan who had COVID-19 were fever and cough. Patients with severe/critical disease were more likely to be male and elderly. Disease severity correlated with increased leukocytes, CRP, PCT, BNP, D-dimer, liver enzymes, and myocardial enzymes, and with decreased lymphocytes and blood oxygen partial pressure.

Construction and use of a risk stratification instrument for vaccination of elderly against Covid-19 / Construção e utilização de instrumento de estratificação de risco para vacinação de idosos contra a Covid-19 / Construcción y uso de un instrumento de estratificación de riesgo para la vacunación del anciano contra el Covid- 19

Objetivo: Relatar a experiência da construção e utilização de um instrumento de estratificação de risco para vacinação de idosos contra a COVID-19. Métodos: Relato da experiência desenvolvida no município de Massapê ­ Ceará, durante o ano de 2021, a partir do início da campanha de vacinação de idosos contra a COVID-19. Descrição da Experiência: Por conta da escassez de imunobiológicos, na fase inicial da vacinação contra a COVID-19, a Secretaria da Saúde do município de Massapê, estado do Ceará, criou um instrumento para estratificação de riscos sanitários, epidemiológicos e sociais dos idosos, contendo seus dados sociodemográficos e as comorbidades. Após o estabelecimento das variáveis, foram estabelecidos escores para os estratos de risco, que foram classificados em baixo (um a três pontos), médio (quatro a seis pontos), alto (sete a nove pontos) e muito alto (dez pontos e mais). Considerações Finais: O estudo mostra que, apesar da pandemia de COVID-19, uma crise sanitária global sem precedentes como já dito, ações pontuais, mesmo que localizadas, podem ter efeito em cadeia e ser replicadas em outros cenários e momentos.

Objective: To report the experience of building and using a risk stratification instrument for vaccinating the elderly against COVID-19. Methods: Report of the experience developed in the municipality of Massapê - Ceará, during the year 2021, from the beginning of the vaccination campaign for the elderly against COVID-19. Experience Description: Due to the scarcity of immunobiologicals, in the initial phase of vaccination against COVID-19, the Department of Health of the municipality of Massapê, state of Ceará, created an instrument to stratify the health, epidemiological and social risks of the elderly, containing sociodemographic data and comorbidities of the elderly. After establishing the variables, scores were established for the risk strata, which were classified as low (one to three points), medium (four to six points), high (seven to nine points) and very high (ten points and more). Final Considerations: The study shows that, despite the COVID-19 pandemic, an unprecedented global health crisis as already mentioned, specific actions, even if localized, can have a chain effect and be replicated in other scenarios and times.

Subacute thyroiditis and thyrotoxicosis after SARS-CoV-2 vaccine: report of 2 cases / Tiroiditis subaguda y tirotoxicosis posterior a vacuna contra SARS-CoV-2: reporte de 2 casos

La enfermedad por coronavirus SARS-CoV-2 que surgió en el año 2019 (COVID-19), ha obligado al rápido desarrollo de vacunas para prevenir su propagación e intentar controlar la pandemia. Dentro de las vacunas desarrolladas, las primeras en ser aprobadas con una tecnología nueva en el campo de la vacunación, fueron las vacunas basadas en ARNm (ácido ribonucleico mensajero), que lograron tasas de efectividad cercanas al 95 % para la prevención de la enfermedad COVID-19 grave. Los eventos adversos comunes son reacciones locales leves, pero ha habido varios informes de pacientes que desarrollaron tiroiditis subaguda y disfunción tiroidea después de recibir la vacuna contra SARS-CoV-2. Este artículo presenta dos casos de tiroiditis subaguda poco después de recibir la vacuna contra COVID-19

The SARS-CoV-2 coronavirus disease which emerged in 2019 (COVID-19), has forced the rapid development of vaccines to prevent the spread of infection and attempt to control the pandemic. Among the vaccines developed, one of the first to be approved with a new technology in the field of vaccination, was the mRNA (messenger ribonucleic acid) vaccine, with rates of effectiveness close to 95% for the prevention of severe COVID-19 disease. Common adverse events are mild local reactions, but there have been some reports of patients developing sub-acute thyroiditis and thyroid dysfunction after receiving the SARS-CoV-2 vaccine. This article presents two case reports of subacute thyroiditis shortly after receiving the COVID-19 vaccine
