The objective of this study was to analyse microbiological organisms in different locations and regions for physical activity in the city of João Pessoa, Brazil. Samples were collected on various objects used, such as: mattresses, drinking fountains, gloves, cell phones and others. The samples were collected in João Pessoa-PB, following the Standard Operating Procedure-SOP/ Microbiology of a specialized laboratory. The collection took place in the five macro-regions: North, South, East, West and Center. Foreach region samples were collected in one public place (square), a private one (gym) and one school (public or private), totaling fifteen collected sites and 450 samples. The following microorganisms were studied in all analyzed surfaces: Bacillus sp, Escherichia Coli, Klebsiella sppor Enterobacter sppand Coag. Neg. Staphylococcus.All regions had a high contamination level by some microorganism. The highest rates were found in the western, central and northern regions -96, 94 and 93% respectively. The Coag. Neg.Staphylococcus presented the highest and lowest incidence rates in the South and East regions, with 43.33 and 6.67%, respectively, as well as Klebsiella sppor Enterobacter spp, which presented high levels. It is concluded that there is a microorganisms' contamination in the most varied places and regions where physical activity practices are developed, with a predominance of Coag. Neg.Staphylococcusand Klebsiella sppor Enterobacter spp. These results lead to a warning about the hygiene importance in places for physical activity practice, especially in pandemic times (COVID-19), since almost all the evaluated surfaces were contaminated.

Abstract Up to today, there is no specific treatment against SARS-CoV-2 / COVID-19 infection; there the necessity to search for alternatives that help patients with COVID-19. The objective of this study was to review the use of ozone therapy as adjunct treatment for SARS-CoV-2 / COVID-19 infection, highlighting the mechanisms of action, forms of application and current clinical evidence. A systematic review was conducted in electronic databases, searching the terminology Ozone "or" Ozone therapy "and" SARS-CoV-2 or COVID-19 or Coronavirus. Results: nineteen studies were included; ten were editorials, comments, brief reports or reviews, and nine clinical studies. We found that ozone therapy could be favorable for treating patients infected with SARS-CoV-2 / COVID-19, through a direct antiviral effect, regulation of oxidative stress, immunomodulation and improvement of oxygen metabolism. Patients who were treated with ozone therapy responded favorably; therefore, ozone therapy appears to be a promising treatment for patients infected with SARS-CoV-2 / COVID-19. Its mechanism of action justifies its use as an adjuvant therapy; however, scientific evidence is based on case series and clinical trials are necessary to corroborate its effectiveness and safety.

INTRODUCCIÓN: La enfermedad COVID-19, además de presentar síntomas respiratorios, puede afectar otros órganos como la piel. Al momento, se han descrito cinco variantes clínicas de manifestaciones cutáneas por COVID-19. Pocos reportes abordan el tema de la gravedad de las dermatosis cutáneas de COVID-19 y el pronóstico. OBJETIVO: Describir patrones clínicos e histológicos de dermatosis en pacientes con COVID-19. Pacientes y MÉTODOS: Es una cohorte para pacientes del IMSS-T1 en León, Guanajuato, México, entre septiembre 2020 y enero 2021. Identificamos pacientes con dermatosis asociada a COVID-19 desde su ingreso hospitalario y aquellos que la desarrollaron durante su estancia. Se les invitó a participar para evaluación clínica y toma de biopsia que fueron descritas por un patólogo experto. RESULTADOS: La frecuencia de las dermatosis por COVID-19 fue de 15,7%. Los que desarrollaron las lesiones durante su estancia hospitalaria presentaron mayor morbi-mortalidad (p = 0,001). Las lesiones vaso-oclusivas fueron las más diagnosticadas y asociadas con mayor mortalidad (p = 0,003). Histológicamente el hallazgo más común fue trombosis superficial y profunda (58%). CONCLUSIONES: Los pacientes que desarrollaron las lesiones durante su hospitalización y aquellos con lesiones vaso-oclusivas tuvieron la mayor morbi-mortalidad. Las lesiones vaso-oclusivas pueden ser un factor de mal pronóstico en pacientes con COVID-19.

BACKGROUND: COVID-19 disease, besides presenting respiratory manifestations, can affect other organs such as kidneys, gastrointestinal system, heart, and skin. So far, five clinical variants of dermatoses have been described. Few reports discuss the severity associated with the cutaneous manifestations of COVID-19 and the prognosis. AIM: To describe the clinical and histopathological patterns of dermatoses in patients with COVID-19 infection. PATIENTS AND METHODS: Prospective cohort study conducted in patients admitted to "IMSS T1" in Leon, Guanajuato, Mexico from September 2020 to January 2021. We identified those with COVID-19 dermatosis from the moment they were admitted; and those who developed them during hospitalization. Patients were invited to participate for a clinical evaluation and biopsy. The biopsies were described by an expert pathologist. RESULTS: The frequency of dermatological lesions was 15.7%. Those who developed dermatosis during their hospital stay presented higher mortality (p = 0.001) and severity of COVID-19 (p = 0.001) Vasoocclusive lesions were the most frequent in the hospital setting, and were associated to higher mortality (p = 0.003). The most frequent histopathological feature was superficial and deep thrombosis (58%). CONCLUSIONS: Patients who developed dermatologic lesions during hospitalization and those with vaso-occlusive dermatoses had higher morbi-mortality. Vaso-occlusive lesions could be considered as a poor prognostic factor.

SUMMARY: Obesity and fatty liver steatosis are already considered metabolic risk factors which may aggravate the severity of COVID-19. This study aims to investigate the correlation between COVID-19 severity, obesity, and liver steatosis and fibrosis. 230 consecutive patients with laboratory-confirmed COVID-19 aged between 15 and 84? years, admitted to a hospital devoted to COVID-19 patients, were enrolled in the study. COVID-19 severity was classified as severe versus non-severe based on admission to ICU. Obesity was assessed by Body Mass Index (BMI). CT-scan was used to check for the liver steatosis. Fibrosis-4 score was calculated. The study was conducted in March-May 2020. Obesity strongly and positively correlated with severe COVID-19 illness r: 0.760 (P<0.001). Hepatic steatosis had rather less of a correlation with COVID-19 severity r: 0.365 (P<0.001). Multivariable-adjusted association between hepatic steatosis or obesity, or both (as exposure) and COVID-19 severity (as the outcome) revealed increased risk of severe COVID-19 illness with obesity (Adjusted model I OR: 465.3, 95 % CI: 21.9-9873.3, P<0.001), with hepatic steatosis (Adjusted model I OR: 5.1, 95 % CI: 1.2-21.0, P<0.025), and with hepatic steatosis among obese patients (Adjusted model I OR: 132, 95 % CI: 10.3-1691.8, P<0.001). Obesity remained the most noticeable factor that strongly correlated with COVID-19 severity, more than liver steatosis. However, the risk to COVID-19 severity was greater in those with both factors: obesity and liver steatosis.

RESUMEN: La obesidad y la esteatosis del hígado graso ya se consideran factores de riesgo metabólico que pueden empeorar la gravedad de la COVID-19. Este estudio tiene como objetivo investigar la correlación entre la gravedad de COVID- 19, la obesidad y la esteatosis y fibrosis hepática. El estudio se realizó en 230 pacientes consecutivos entre 15 y 84 años con COVID-19 confirmado por laboratorio, ingresados en un hospital dedicado a pacientes con COVID-19. La gravedad de COVID-19 se clasificó como grave, versus no grave según el ingreso a la UCI. La obesidad se evaluó mediante el índice de masa corporal (IMC). Se utilizó una tomografía computarizada para verificar la esteatosis hepática. Se calculó la puntuación de Fibrosis-4. El estudio se realizó entre marzo-mayo de 2020. La obesidad se correlacionó fuerte y positivamente con la enfermedad grave de COVID-19 r: 0,760 (P <0,001). La esteatosis hepática tuvo una correlación bastante menor con la gravedad de COVID-19 r: 0.365 (P <0.001). La asociación ajustada multivariable entre la esteatosis hepática u obesidad, o ambas (como exposición) y la gravedad de COVID-19 (como resul- tado) reveló un mayor riesgo de enfermedad grave por COVID- 19 con obesidad (OR del modelo ajustado I: 465,3, IC del 95%: 21,9 -9873,3, P <0,001), con esteatosis hepática (OR del modelo I ajustado: 5,1, IC del 95 %: 1,2-21,0, P <0,025) y con esteatosis hepática entre los pacientes obesos (OR del modelo I ajustado: 132, IC del 95 % : 10,3-1691,8, P <0,001). La obesidad siguió siendo el factor más notable que se correlacionó significativamente con la gravedad de COVID-19, más que la esteatosis hepática. Sin embargo, el riesgo de gravedad de COVID-19 fue mayor en aquellos con ambos factores: la obesidad y esteatosis hepática.

Abstract Placental pathophysiology in SARS-CoV-2 infection can help researchers understand more about the infection and its impact on thematernal/neonatal outcomes. This brief review provides an overview about some aspects of the placental pathology in SARSCoV- 2 infection. In total, 11 papers were included. The current literature suggests that there are no specific histopathological characteristics in the placenta related to SARSCoV- 2 infection, but placentas frominfected women aremore likely to show findings of maternal and/or fetal malperfusion. The most common findings in placentas from infected women were fibrin deposition and intense recruitment of inflammatory infiltrates. The transplacental transmission of this virus is unlikely to occur, probably due to low expression of the receptor for SARS-CoV-2 in placental cell types. Further studies are needed to improve our knowledge about the interaction between the virus and the mother-fetus dyad and the impact on maternal and neonatal/fetal outcomes.

Resumo A fisiopatologia da placenta na infecção por SARS-CoV-2 pode ajudar os pesquisadores a entender mais sobre a infecção e seu impacto nos resultados maternos/neonatais. Esta revisão breve fornece uma visão geral sobre alguns aspectos da patologia placentária na infecção por SARS-CoV-2. Ao todo, 11 artigos foram incluídos. A literatura atual sugere que não há características histopatológicas específicas nas placentas relacionadas à infecção por SARS-CoV-2, mas as placentas de mulheres infectadas têm maior probabilidade de apresentar achados de má perfusão materna e/ou fetal. Os achados mais comuns em placentas de mulheres infectadas foram deposição de fibrina e intenso recrutamento de infiltrado inflamatório. A transmissão transplacentária deste vírus é improvável, devido à baixa expressão do receptor para SARS-CoV-2 em tipos de células da placenta. Mais estudos são necessários para melhorar nosso conhecimento sobre a interação entre o vírus e a díade mãe-feto e o impacto nos resultados maternos e neonatais/fetais.

Introdução:A população idosa constitui um dos grupos mais vulneráveis à infecção pelo novo coronavírus. Tal fragilidade é ainda mais evidente naqueles que residem em Instituições para Idosos, por apresentar maior risco de contaminação e, ainda, de morbimortalidade. Objetivo: Identificar o impacto da COVID-19 na saúde de pessoas idosas residentes nas Instituições de Longa Permanência. Metodologia:Trata-se de estudo retrospectivo de revisão integrativa da literatura, entre os meses de novembro/2020 e março/2021, sintetizando estudos publicados sobre a temática. A partir do objetivo traçado para este estudo, determinamos quais seriam as questões norteadoras: 1. "Quais medidas estão sendo adotadas para minimizar os efeitos da COVID-19 nas Instituições de Longa Permanência para Idosos?" 2. "Quais os principais impactos causados por essas medidas?". Estes eixos colaboram para a compreensão dos acontecimentos de significativa relevância social. Resultados:As instituições para idosos, como ambientes coletivos, possuem residentes com elevada vulnerabilidade à infecção pelo novo coronavírus. Naqueles idosos acometidos por quadros de demência e outras doenças neurológicas, o isolamento social aprofunda a gravidade da infecção pela COVID-19, dificultando, assim, as atividades relacionadas à atenção e assistência realizadas pelos cuidadores. Ademais, caracteriza-se como medida fundamental a adoção do rastreamento laboratorial precoce para potencializar a prevenção de casos e promover o controle da infecção. Percebe-se ainda uma deficiência referente à construção de um protocolo com medidas de profilaxia e manejo adequado de modo mais direcionado dentro dessas instituições. Conclusão:Torna-se urgente um olhar mais atento às necessidades da população idosa, especialmente dogrupo institucionalizado, de modo a promover políticas de investimento em cuidados de saúde integrais e realizados por equipe multiprofissional (AU).

Introduction:The elderly population is one of the groups most vulnerable to infection by the new coronavirus. Such fragility is even more evident in those who live in Institutions for the Aged, as it presents a higher risk of contamination and, even, of morbidity and mortality. Objective: To identify the impact of COVID-19 on the health of elderly people residing in Long Term Institutions for the Aged. Methodology:This is a retrospective study of integrative literature review, between the months of November/2020 and March/2021, synthesizing published studies on the theme. Based on the objective outlined for this study, we determined what the guiding questions would be: 1. "What measures are being taken to minimize the effects of COVID-19 on Long Term Care Institutions for the Aged?" 2. "What are the main impacts caused by these measures?. These axes contribute to the understanding of events of significant social relevance. Results:Institutions for the aged, as collective environments, have residents with high vulnerability to infection with the new coronavirus. In those aged people affected by dementia and other neurological diseases, social isolation deepens the severity of the infection by COVID-19, thus hampering the activities related to the care and assistance performed by caregivers. In addition, the adoption of early laboratory screening is characterized as a fundamental measure to enhance the prevention of cases and promote infection control. It is also perceived a deficiency regarding the construction of a protocol with prophylaxis measures and adequate management in a more targeted way within these institutions.Conclusions:It is urgent to look more closely at the needs of the aged population, especially the institutionalized group, in order to promote investment policies in comprehensive health care carried out by a multidisciplinary team (AU).

Introducción: la población anciana es uno de los grupos más vulnerables a la infección por el nuevo coronavirus. Tal fragilidad es aún más evidente en quienes viven en Instituciones de Ancianos, ya que presenta un mayor riesgo de contaminación e, incluso, de morbilidad y mortalidad. Objetivo: Identificar el impacto del COVID-19 en la salud de los ancianos que residen en Instituciones de Atención de Larga Duración. Metodología: Se trata de un estudio retrospectivo de revisión integradora de la literatura, entre los meses de noviembre/2020 y marzo/2021, sintetizando los estudios publicados sobre el tema. Con base en el objetivo delineado para este estudio, determinamos cuáles serían las preguntas orientadoras: 1. "¿Qué medidas se están tomando para minimizar los efectos del COVID-19 en las Instituciones de Atención de Larga Duración para el Anciano?" 2. "¿Cuáles son los principales impactos provocados por estas medidas?". Estos ejes contribuyen a la comprensión de hechos de relevancia social significativa.Resultados:Las instituciones para los ancianos, como entornos colectivos, tienen residentes conalta vulnerabilidad a la infección por el nuevo coronavirus. Aquellos ancianos afectados por demencia y otras enfermedades neurológicas, el aislamiento social profundiza la gravedad de la infección por COVID-19, dificultando así las actividades relacionadas con el cuidado y asistencia que realizan los cuidadores. Además, la adopción del cribado precoz de laboratorio se caracteriza por ser una medida fundamental para potenciar la prevención de casos y promover el control de infecciones. También se percibe una deficiencia en la construcción de un protocolo con medidas de profilaxis y manejo adecuado de manera más focalizada dentro de estas instituciones. Conclusiones: Es urgente mirar más de cerca las necesidades de la población anciana, especialmente del grupo institucionalizado, para promover políticas de inversión en la atención integral de salud llevadas a cabo por un equipo multidisciplinario (AU).

ABSTRACT Objective: To evaluate and discuss the prevention and management of dental trauma in primary teeth during the COVID-19 pandemic. Material and Methods: Critic literature review, searching electronic databases and Google for articles and guidelines published in English that described prevention and management of dental trauma in primary dentition during the pandemic of COVID-19. Results: 5 publications regarding management and 1 leaflet about prevention for parents were identified. Urgent care is required when the child presents tooth fracture resulting in pain or causing soft tissue trauma and luxation affecting bite. Avulsed teeth should not be replanted and advice and self-help may be sufficient in some situations. Instructions about soft diet and hygiene must be provided. Remote consults are recommended for non-urgent situations and during follow-up to evaluate the presence of sequelae. Aerosol generating procedures should be avoided and, in cases of poor prognosis, extraction is recommended to prevent recurring visits to the dental office. Conclusion: During COVID-19 pandemic, remote consults should be recommended to evaluate traumatic dental injuries in primary dentition. Follow-up should not be neglected and may be performed through remote consultation.

ABSTRACT Objective: To determine the relationship of transmission of COVID-19 virus knowledge with dental care during a pandemic. Material and Methods: Online questionnaire using Google forms distributed through social media (WhatsApp groups, Facebook, line groups) using a combination of convenience and snowball sampling. The level of knowledge about coronavirus transmission was measured using a questionnaire consisting of 5 statement items. This questionnaire uses the Guttman scale with 3 response and anxiety categories for dental care as measured using a modified questionnaire from the Dental Fear Survey. This questionnaire consisted of 9 question items using a Likert scale. Results: 285 respondents came from WhatsApp media users (89.9%) with an average age of 29.91 years. Respondents who experienced "dental health problems" during the pandemic were 44.7%. The knowledge of respondents about the transmission of the COVID-19 virus in dental care was 79.9% and the knowledge of the fear of caring during the pandemic period was 31.85% afraid. Statistical analysis showed a significant relationship between knowledge about transmission of the COVID-19 virus and fear of dental care (rs=0.388, p<0.001). Conclusion: The results obtained have a significant relationship between knowledge about transmission and fear for dental care during the COVID-19 pandemic in South Sulawesi Province.

BACKGROUND@#Coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has rapidly spread throughout the world. In this study, we aimed to identify the risk factors for severe COVID-19 to improve treatment guidelines.@*METHODS@#A multicenter, cross-sectional study was conducted on 313 patients hospitalized with COVID-19. Patients were classified into two groups based on disease severity (nonsevere and severe) according to initial clinical presentation. Laboratory test results and epidemiological and clinical characteristics were analyzed using descriptive statistics. Univariate and multivariate logistic regression models were used to detect potential risk factors associated with severe COVID-19.@*RESULTS@#A total of 289 patients (197 nonsevere and 92 severe cases) with a median age of 45.0 (33.0, 61.0) years were included in this study, and 53.3% (154/289) were male. Fever (192/286, 67.1%) and cough (170/289, 58.8%) were commonly observed, followed by sore throat (49/289, 17.0%). Multivariate logistic regression analysis suggested that patients who were aged ≥ 65 years (OR: 2.725, 95% confidence interval [CI]: 1.317-5.636; P = 0.007), were male (OR: 1.878, 95% CI: 1.002-3.520, P = 0.049), had comorbid diabetes (OR: 3.314, 95% CI: 1.126-9.758, P = 0.030), cough (OR: 3.427, 95% CI: 1.752-6.706, P < 0.001), and/or diarrhea (OR: 2.629, 95% CI: 1.109-6.231, P = 0.028) on admission had a higher risk of severe disease. Moreover, stratification analysis indicated that male patients with diabetes were more likely to have severe COVID-19 (71.4% vs. 28.6%, χ2 = 8.183, P = 0.004).@*CONCLUSIONS@#The clinical characteristics of those with severe and nonsevere COVID-19 were significantly different. The elderly, male patients with COVID-19, diabetes, and presenting with cough and/or diarrhea on admission may require close monitoring to prevent deterioration.

OBJECTIVE@#Traditional Chinese medicine plays a significant role in the treatment of the pandemic of coronavirus disease 2019 (COVID-19). Tanreqing Capsule (TRQC) was used in the treatment of COVID-19 patients in the Shanghai Public Health Clinical Center. This study aimed to investigate the clinical efficacy of TRQC in the treatment of COVID-19.@*METHODS@#A retrospective cohort study was conducted on 82 patients who had laboratory-confirmed mild and moderate COVID-19; patients were treated with TRQC in one designated hospital. The treatment and control groups consisted of 25 and 57 cases, respectively. The treatment group was given TRQC orally three times a day, three pills each time, in addition to conventional Western medicine treatments which were also administered to the control group. The clinical efficacy indicators, such as the negative conversion time of pharyngeal swab nucleic acid, the negative conversion time of fecal nucleic acid, the duration of negative conversion of pharyngeal-fecal nucleic acid, and the improvement in the level of immune indicators such as T-cell subsets (CD3, CD4 and CD45) were monitored.@*RESULTS@#COVID-19 patients in the treatment group, compared to the control group, had a shorter negative conversion time of fecal nucleic acid (4 vs. 9 days, P = 0.047) and a shorter interval of negative conversion of pharyngeal-fecal nucleic acid (0 vs. 2 days, P = 0.042). The level of CD3@*CONCLUSION@#Significant reductions in the negative conversion time of fecal nucleic acid and the duration of negative conversion of pharyngeal-fecal nucleic acid were identified in the treatment group as compared to the control group, illustrating the potential therapeutic benefits of using TRQC as a complement to conventional medicine in patients with mild and moderate COVID-19. The underlying mechanism may be related to the improved levels of the immune indicator CD3

INTRODUCCIÓN: En 6 meses se notificaron más de 400 mil fallecidos por COVID-19. Han surgido múltiples investigaciones para comprender su etiopatogenia, siendo la autopsia médica uno de los mejores procedimientos para obtener información. Presentamos una revisión respecto a hallazgos post mortem publicados hasta mayo, 2020. RESULTADOS: Se recolectaron 12 estudios, de un total de 109 pacientes cuyo deceso fue por complicación respiratoria, predominó el sexo masculino, edad avanzada y con múltiples comorbilidades. El estudio PCR se realizó principalmente para diagnóstico. Se demostró ARN viral en riñón, hígado, corazón, cerebro y otros órganos. Los autores relataron presencia de micro y/o macro trombosis, en 50 de 109 casos, sobre todo a nivel pulmonar y renal, de tipo microscópica y relacionados a signos de shock. Desde la perspectiva anatomopatológica, se centra en alteraciones pulmonares y renales: daño alveolar difuso, injuria tubular aguda, microtrombos y otros signos de alteración microcirculatoria. Los estudios inmunohistoquímicos, de inmunofluoresencia y microscopía electrónica sugieren tropismo del virus por células epiteliales y estromales a nivel pulmonar y renal. En otros órganos se encuentran elementos morfológicos inespecíficos, atribuibles a patologías de base o shock. CONCLUSIÓN: El patrón histopatológico de daño alveolar difuso es frecuente, principalmente en fase exudativa o temprana. En el tejido renal destaca la injuria tubular aguda y daño microcirculatorio. El número y la descripción de muestras en otros órganos es reducida, siendo necesaria mayor casuística. La trombosis, es un trastorno prevalente en pulmones y riñones de pacientes con signos de shock. El tipo de trombo con más frecuencia descrito, es el microtrombo. Si bien se puede explicar como gatillante del fenómeno trombótico la interacción entre agente y huésped, otros factores deben ser estudiados para dilucidar la patogenia.

BACKGROUND@#The proportion of recurrences after discharge among patients with coronavirus disease 2019 (COVID-19) was reported to be between 9.1% and 31.0%. Little is known about this issue, however, so we performed a meta-analysis to summarize the demographical, clinical, and laboratorial characteristics of non-recurrence and recurrence groups.@*METHODS@#Comprehensive searches were conducted using eight electronic databases. Data regarding the demographic, clinical, and laboratorial characteristics of both recurrence and non-recurrence groups were extracted, and quantitative and qualitative analyses were conducted.@*RESULTS@#Ten studies involving 2071 COVID-19 cases were included in this analysis. The proportion of recurrence cases involving patients with COVID-19 was 17.65% (between 12.38% and 25.16%) while older patients were more likely to experience recurrence (weighted mean difference (WMD)=1.67, range between 0.08 and 3.26). The time from discharge to recurrence was 13.38 d (between 12.08 and 14.69 d). Patients were categorized as having moderate severity (odds ratio (OR)=2.69, range between 1.30 and 5.58), while those with clinical symptoms including cough (OR=5.52, range between 3.18 and 9.60), sputum production (OR=5.10, range between 2.60 and 9.97), headache (OR=3.57, range between 1.36 and 9.35), and dizziness (OR=3.17, range between 1.12 and 8.96) were more likely to be associated with recurrence. Patients presenting with bilateral pulmonary infiltration and decreased leucocyte, platelet, and CD4@*CONCLUSIONS@#The main factors associated with the recurrence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) after hospital discharge were older age, moderate severity, bilateral pulmonary infiltration, laboratory findings including decreased leucocytes, platelets, and CD4
