Covid-19 em Viçosa-MG: análise quantitativa, vacinal, etária e de gênero das pessoas infectadas e os impactos da vacinação / Covid-19 in Viçosa-MG: quantitative, vaccine, age, and gender analysis of infected people and the impacts of vaccination

Este estudo teve como objetivo analisar o número de casos e óbitos por Covid-19 em relação a gênero e idade, quantidade total de vacinas aplicadas e relação entre a aplicação das vacinas e número de mortes, de janeiro a novembro de 2021, na cidade e região de Viçosa, Minas Gerais. Os dados foram fornecidos pelo Setor de Vigilância Epidemiológica do município e pelos boletins diários da prefeitura. Em média, houve mais de mil casos de infectados/mês de janeiro a julho, a maior parte adultos do gênero feminino. A mortalidade também foi maior entre as mulheres. Foi registrada queda do número de casos e de mortes coincidente com a aplicação da primeira dose de vacina em pessoas sem comorbidades e com início de aplicação da segunda dose nos grupos prioritários. Tal achado indica a importância da imunização coletiva no controle da pandemia.

This study aimed to analyze the number of cases and deaths from Covid-19 in relation to gender and age, the total vaccines applied, and the relationship between the vaccine application and the number of deaths between January and November 2021, in the municipality and region of Viçosa, state of Minas Gerais. Data were provided by the Epidemiological Surveillance Sector of the municipality of Viçosa and by the Daily Bulletins, published by the city hall. On average, there were more than 1,000 cases per month from January to July, mostly female adults. Mortality was also higher for females. There was a drop in the number of cases and deaths, coincident with the application of the first dose of vaccine in people without comorbidities and the initial period of application of the second dose in priority groups, indicating the importance of collective immunization to control the pandemic.

Effectiveness and impact of Covid-19 response and vaccination challenges in Namibia: a systematic review

Introduction: Namibia, as with many countries around the world is experiencing devastating impact of Covid-19 disease on the economy, psycho-social interactions, and well-being of the populace. These countries implemented several measures to limit the spread of the virus responsible for the severe acute respiratory syndrome (SARS-CoV-2). Namibia also put measures in place to curtail the spread and fatalities due to the virus. However, the nature and implementation strategies of Public Health regulations seriously have impact on preventing the spread and curtailing fatalities arising from the virus. Objective: This article presents a report on the effectiveness and impact of Public Health measures instituted by the Health Authority towards curtailing the scourge of covid-19 on the general populace. Method: Elements of the PRISMA protocol was utilised in the review which enabled the synthesis of data on focused area. Multifaceted databases on covid19 such as Scopus, ScienceDirect, Google Scholar, World Health Organisation and the Ministry of Health and Social Services of Namibia (MoHSS) among others was used. Result: A steady increase in covid-19 infection at an average rate of eleven (11) per day was noted in the country up till June 2021. Highest rate was linked to densely populated regions of Erongo and Khomas. Control measures for infection prevention and vaccination drive was ineffective majorly as a result of misinformation. 3

Risk factors for hospitalization and death due to COVID-19 among frail community-dwelling elderly people: a retrospective cohort study

ABSTRACT BACKGROUND: Advanced age, multiple chronic diseases and frailty have been correlated with worse prognosis among coronavirus disease 2019 (COVID-19) inpatients. OBJECTIVE: To investigate potential risk factors for hospitalization and death due to COVID-19 among frail community-dwelling elderly people. DESIGN AND SETTING: Retrospective cohort study of patients followed up at a geriatric outpatient clinic in Belo Horizonte, Minas Gerais, Brazil. METHODS: The associations of demographic characteristics (age and sex) and clinical characteristics (frailty, multimorbidity, number of medications with long-term use, obesity, smoking, diabetes mellitus, pulmonary diseases, cardiovascular diseases, cerebrovascular disease, and chronic kidney disease) with the risk of hospitalization and death due to COVID-19 were explored using a multivariable logistic regression model. RESULTS: 5,295 patients (mean age 78.6 ± 9.4 years; 72.6% females) were included. After adjustments, the number of medications with long-term use was found to increase the odds of hospitalization due to COVID-19 (odds ratio, OR: 1.13; 95% confidence interval, CI: 1.06-1.22). Frailty, multimorbidity and diabetes mellitus also increased the odds of hospitalization (OR: 1.06, 95% CI: 1.02-1.09; OR: 1.17, 95% CI: 1.09-1.26; and OR: 2.27, 95% CI: 1.45-3.54, respectively) and the odds of death due to COVID-19 (OR: 1.07, 95% CI: 1.00-1.14; OR: 1.16, 95% CI: 1.03-1.32; and OR: 2.69, 95% CI: 1.79-6.14, respectively). CONCLUSIONS: Multimorbidity, frailty and diabetes mellitus increased the odds of hospitalization and death due to COVID-19 and the number of medications with long-term use increased the odds of hospitalization due to COVID-19 among frail community-dwelling elderly people.

Ethics and Responsibility in Facing COVID-19 in the Context of Brazilian Public Agents

The year 2020 will be remembered as the year in which a pandemic caused by the SARS-CoV-2 virus precipitated a major disruption in the functioning of contemporary societies. A global event with peculiar regional consequences. It is in this context that we will discuss the ethical aspects of the actions under the responsibility of public officials, namely the ones on national Brazilian relevance for the confrontation of COVID-19. The analysis of the pandemic's effects in Brazil should be based not only on the events triggered at the current moment, whose transience is still an insufficiently known factor, but also on the social, political, and historically economic determinants that heavily interfere in the present events, as well as in the post epidemic future, highlighting the possible scenarios that the political normative, governmental, social, and economic choices underway point to. The tragedy of our time once again presents us with a challenge that is not new, the challenge of a new order, a global order of survival and, therefore, necessarily, a new ethic, an ethic of a global and profound responsibility. This path can only be treated with wisdom and compassion through a model of responsible governance.

El 2020 será recordado como el año en el cual una pandemia causada por el virus SARS-CoV-2 precipitó una mayor disrupción en el funcionamiento de las sociedades contemporáneas. Se trata de un evento global con peculiares consecuencias regionales. Es en este contexto que discutiremos los aspectos éticos de las acciones bajo la responsabilidad de los agentes oficiales, particularmente aquellos de relevancia nacional para el tratamiento del COVID-19 en Brasil. El análisis de los efectos de la pandemia en el país debiera estar basado no solo en los eventos desencadenados en el momento presente, cuya provisionalidad constituye un factor aún insuficientemente conocido, sino también en los determinantes sociales, políticos y económicos que históricamente han tenido una alta injerencia en los eventos actuales, así como en el futuro pos-pandémico, resaltando los escenarios posibles a los que apuntan las políticas normativas, gubernamentales y sociales y las alternativas económicas en curso. La tragedia de nuestro tiempo nos confronta una vez más con un desafío que no es nuevo, el reto de un nuevo orden, un orden global de supervivencia y, por lo tanto, necesariamente, con una nueva ética, una ética de una profunda responsabilidad global. Este camino solo puede ser abordado con sabiduría y compasión a través de un modelo de gobernanza responsable.

O ano de 2020 será lembrado como o ano no qual uma pandemia causada pelo vírus sars-CoV-2 provocou uma grande ruptura no funcionamento das sociedades contemporâneas. Um evento global com consequências regionais peculiares. É nesse contexto que discutimos os aspectos éticos das ações que estavam sob responsabilidade de agentes públicos, a saber, os agentes de relevância nacional no enfrentamento da covid-19 no Brasil. A análise dos efeitos da pandemia no Brasil deve se basear não somente nos eventos desencadeados no momento - cuja transição ainda é um fator insuficientemente conhecido -, mas também nos determinantes sociais, políticos e historicamente econômicos que interferem significativamente nos eventos atuais, bem como no futuro pós-epidêmico, com destaque para os possíveis cenários que as escolhas políticas normativas, governamentais, sociais e econômicas em andamento apontam. A tragédia do nosso tempo nos apresenta novamente um desafio que não é inédito: o desafio de uma nova ordem, uma ordem global de sobrevivência e, portanto, necessariamente, uma nova ética, uma ética de uma responsabilidade global e profunda. Esse caminho só pode ser tratado com sabedoria e compaixão mediante um modelo de governança responsável.

Taquicardia auricular macro-reentrante del tipo flutter auricular en paciente de dos meses infectado con SARS-CoV-2

Introducción: El 11 de marzo de 2020 se confirmaron los primeros casos de la enfermedad en Cuba. Objeto: Examinar una complicación de la infección por SARS-CoV-2 infrecuente en edad pediátrica y su tratamiento. Presentación del caso: Lactante de 2 meses de edad producto de un parto distócico por cesárea a las 41,5 semanas, procedente de la provincia de Guantánamo. Por condiciones maternas permaneció con su madre en el hospital durante 45 días. Egresa y a los 15 días en casa, consultan por fiebre de 38 ℃ durante tres días consecutivos. Se constata frecuencia cardiaca muy elevada y estado eutérmico. El test de antígeno y las pruebas de reacción en cadena de la polimerasa con transcriptasa inversa y PCR para SARS-CoV-2 fueron positivas, por lo que se ingresa en terapia intensiva pediátrica con impresión diagnóstica de taquicardia supraventricular que se define finalmente como flutter auricular. El tratamiento aplicado controló la arritmia cardiaca y contribuyó a su favorable evolución posterior. Conclusiones: Los hallazgos del examen físico y los datos en la anamnesis permiten realizar el diagnóstico del paciente en su etapa temprana. La fisiopatología de las complicaciones en niños está en la regulación local de la expresión de los receptores ACE2, aumento de la producción de catecolaminas y una mayor incidencia de toxicidad por medicamentos que producen lesión cardíaca aguda y arritmia, síntomas que pueden estar asociados con disfunción del sistema respiratorio y cambios hematológicos o no en la edad pediátrica.

Introduction: On March 11, 2020, the first cases of COVID-19 were confirmed in Cuba. Purpose: To examine a complication of SARS-CoV-2 infection uncommon in pediatric ages and its treatment. Case presentation: A 2-month-old infant from Guantánamo province was delivered by cesarean section at 41.5 weeks. Due to maternal conditions, the newborn remained with the mother in the hospital for 45 days. Then the newborn was discharged and after 15 days at home was evaluated due to fever of 38 ° C during three consecutive days. A very high heart rate and euthermic state were observed. The antigen test and reverse transcriptase polymerase chain reaction and PCR tests for SARS-CoV-2 were positive, so the newborn was admitted to the pediatric intensive care unit with diagnostic impression of supraventricular tachycardia that is finally defined as atrial flutter. The treatment applied controlled the cardiac arrhythmia and contributed to its subsequent favorable evolution. Conclusions: The findings of the physical examination and the data in the anamnesis allow the diagnosis of the patient in its early stage. The pathophysiology of complications in children is in the local regulation of ACE2 receptor expression, increased catecholamine production and an increased incidence of toxicity by drugs that produce acute cardiac injury and arrhythmia, symptoms that may be associated with dysfunction of the respiratory system and hematological changes or not in pediatric age.

COVID-19, aterosclerosis y la respuesta inflamatoria en la enfermedad reumática / COVID - 19, atherosclerosis and the inflammatory response in rheumatic disease

Introducción: La enfermedad por el coronavirus 2019 (COVID-19) es causada por el síndrome respiratorio agudo severo coronavirus-2 (SARS-CoV-2). Además de la invasión tisular directa, el SARS-CoV-2 también puede provocar una respuesta inmune exagerada del huésped, que con frecuencia conduce a una tormenta de citocinas, que contribuye, significativamente, a la disfunción multiorgánica. Las enfermedades autoinmunes se caracterizan por un estado proinflamatorio, aterosclerosis acelerada e incremento de la incidencia de complicaciones vasculares por lo que en estos pacientes existe un alto riesgo de complicaciones ante la presencia del SARS-CoV-2. La alteración en la regulación del sistema inmunológico, el aumento de la demanda metabólica y la actividad procoagulante probablemente explican parte del mayor riesgo de resultados adversos en las personas con enfermedad aterosclerótica relacionada con la COVID-19. Objetivo: Actualizar los conocimientos del personal de salud en el manejo de estas enfermedades. Método: Se realizó una búsqueda de artículos en PubMed, SciELO y Google Scholar con estrategia de vocabulario controlado, de diciembre 2019 a noviembre 2020. Se seleccionaron un total de 50 artículos. Desarrollo: La elevada producción de autoanticuerpos ya sea secundaria a la enfermedad reumática o por una infección intercurrente, puede estar implicada en el desarrollo de la disfunción endotelial, la progresión y la ruptura de la placa aterosclerótica. Conclusiones: Se ha demostrado que estas enfermedades crónicas autoinmunitarias se asocian a una elevada morbimortalidad cardiovascular por lo que el médico de estos tiempos tiene que ser capaz de reconocer estos pacientes(AU)

Introduction: Coronavirus disease 2019 (Covid-19) is caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). In addition to direct tissue invasion, SARS-CoV-2 can also elicit an exaggerated host immune response, often leading to a cytokine storm, significantly contributing to multi-organ dysfunction. Autoimmune diseases are characterized by a pro-inflammatory state, accelerated atherosclerosis and an increased incidence of vascular complications, which is why there is a high risk of complications in the presence of SARS-CoV-2 in these patients. Altered immune system regulation, increased metabolic demand, and procoagulant activity likely explain part of the increased risk of adverse outcomes in people with Covid-19-related atherosclerotic disease. Objective: To update the knowledge of health personnel in the management of these diseases. Method: We reviewed articles in PubMed, SciELO and Google Scholar with a controlled vocabulary strategy, from December 2019 to November 2020. We selected a total of 50 articles. Findings: The high production of autoantibodies, whether secondary to rheumatic disease or due to intercurrent infection, may be involved in the development of endothelial dysfunction, the progression and rupture of the atherosclerotic plaque. Discussion: It has been shown that these autoimmune chronic diseases are associated with high cardiovascular morbidity and mortality, so the doctor of these times must be able to recognize these patients(AU)

El enigma del coronavirus - Covid-19 durante el Bicentenario de la Independencia del Perú - El síndrome poscovid - Las vacunas - La gestante / The coronavirus conundrum - Covid-19 during the Bicentennial of the Independence of Peru - The postcovid syndrome The vaccines - The pregnant woman

RESUMEN Han trascurrido dieciocho meses desde que se declaró como pandemia la infección COVID-19 ocasionada por el SARS-CoV-2. No existe aún tratamiento contra el virus, salvo el sintomático y recuperativo. El rápido reconocimiento del nuevo coronavirus permitió la elaboración de vacunas que están siendo usadas de emergencia y han permitido disminuir los casos graves, hospitalizaciones, uso de unidades de cuidados intensivos, ventilación mecánica y muertes. Pero aún quedan incógnitas sobre las modificaciones genéticas y variantes que el virus utiliza para una mejor invasión y adaptación a las defensas del ser humano, así como sobre sus consecuencias inmediatas y a largo plazo en el hombre, la mujer y su niño. Parece distante alcanzar la inmunización de rebaño, porque desconocemos la inmunidad proporcionada por la infección y por las vacunas, así como su duración, y por la importante parte de la población que no desea vacunarse. Además, existe insuficiente capacidad de oferta de vacunas, accesibilidad limitada a los servicios de salud, situación económica desfavorable, incremento de la pobreza y sus consecuencias, disminución temporal de la expectativa de vida y otras complicaciones secundarias a la infección por el virus. La presente revisión es un recuento breve de lo avanzado recientemente en el conocimiento y manejo del COVID-19, en momentos en que el Perú celebra el Bicentenario de la Independencia del país del dominio español, un 28 de julio de 1821, y que encuentra a los peruanos en medio de una pandemia agresiva, elusiva y mortal, y con aspectos humanos, poblacionales, económicos y políticos a resolver.

ABSTRACT Eighteen months have passed since the COVID-19 infection caused by SARS-CoV-2 was declared a pandemic. There is still no treatment for the virus other than symptomatic and recuperative. The rapid recognition of the novel coronavirus allowed the development of vaccines that are being used on an emergency basis and have led to a decrease in severe cases, hospitalizations, use of intensive care units, mechanical ventilation and deaths. But there are still unknowns about the genetic modifications and variants that the virus uses for better invasion and adaptation to human defenses, as well as about its immediate and long-term consequences in men, women and their children. Herd immunization seems distant to achieve, because we do not know the immunity provided by the infection and vaccines, as well as its duration, and because a large part of the population that does not want to be vaccinated. In addition, there is insufficient vaccine supply capacity, limited accessibility to health services, unfavorable economic situation, increased poverty and its consequences, temporary decrease in life expectancy and other complications secondary to infection by the virus. The present review is a brief account of recent advances in the knowledge and management of COVID-19, at a time when Peru is celebrating the Bicentennial of the country's Independence from Spanish rule, on July 28, 1821, and when Peruvians find themselves in the midst of an aggressive, elusive and deadly pandemic, with human, population, economic and political issues to be resolved.

Manifestaciones orales y disfunción olfativa y gustativa en el síndrome respiratorio agudo severo por corona virus 2 (VIRUS SARS-COV-2): una revisión sistemáticaA / Oral Manifestations and Olfactory and Gustatory Dysfunction in Severe Acute Respiratory Syndrome Corona Virus 2 (SARSCov-2 Virus) Disease: A Systematic Review

La enfermedad del corona virus 2 del síndrome respiratorio agudo severo (virus SARS-CoV-2) apareció por primera vez en diciembre de 2019 en Wuhan, China, y desde entonces se ha extendido rápidamente por todo el mundo. Desde entonces, el brote de esta grave enfermedad viral se ha convertido en una amenaza global para la humanidad. El diagnóstico precoz y el aislamiento son las medidas más importantes necesarias para prevenir su propagación. La evidencia anecdótica reciente ha sugerido manifestaciones orales con o sin deterioro olfativo y gustativo en asociación con la enfermedad por coronavirus (COVID-19). La enzima convertidora de angiotensina-2 (ECA-2) se expresa en la mucosa oral en grandes cantidades y, por tanto, puede contribuir a las primeras manifestaciones de esta enfermedad viral mortal. Las manifestaciones bucales de la enfermedad por coronavirus pueden presentarse en forma de lesiones ulcerativas irregulares en relación con diferentes partes de la cavidad oral y, en particular, en relación con la mucosa adherida en la región del paladar duro, así como inflamación y posterior atrofia de las diversas papilas de la lengua. La disfunción olfativa y gustativa asociada también puede conducir a una pérdida parcial y / o incluso completa de la capacidad para oler y saborear en las primeras etapas del inicio de la enfermedad. La evidencia también ha sugerido la presencia de ácido nucleico del SARS-CoV-2 en la saliva humana, lo que la convierte en portadora de la enfermedad viral infecciosa y ayuda en su diagnóstico. Hemos buscado sistemáticamente la base de datos médica para el mismo y hemos revisado toda la literatura disponible hasta el 29 de junio de 2020

Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2 virus) disease had first appeared in December 2019 in Wuhan, China and has been spreading quickly throughout the world since then. Since then, the outbreak of this severe viral disease has become a global threat to humanity. An early diagnosis and isolation are the most significant measures required to prevent its spread. Recent anecdotal evidence has suggested oral manifestations with or, without olfactory and gustatory impairment in association with corona virus disease (COVID-19). Angiotensin converting enzyme-2 (ACE-2) is expressed in oral mucosa in large amounts and can, thus, contribute in the early manifestations of this deadly viral disease. The oral manifestations of corona virus disease can occur in the form of irregular ulcerative lesions in relation to different parts of the oral cavity and particularly, in relation to the attached mucosa in the hard palate region as well as inflammation and subsequent, atrophy of the various tongue papilla. The associated olfactory and gustatory dysfunction can, also, lead to partial and/or, even a complete loss of the ability to smell and taste in the early stages of the disease onset. Evidence has, also, suggested the presence of SARS-CoV-2 nucleic acid in human saliva making it the carrier of the infectious viral disease as well as aiding in its diagnosis. We have systemically searched medical database for the same and have reviewed all the literature available up to 29th of June 2020.

La incógnita del coronavirus - ¿Una tercera ola? - Vacunas y variantes virales -La gestante y su niño

El virus SARS-CoV-2 sigue reproduciéndose velozmente y muestra variantes más infecciosas. La segunda ola de la enfermedad va apaciguándose en Europa y Estados Unidos de América del Norte, menos en América del Sur. En el Perú, las cifras de fallecidos han sido sinceradas a más del doble, encontrándose mayor mortandad en los hombres y en los mayores de 70 años. Se ha corroborado en el mundo que la gestante sufre una enfermedad más severa -a veces con un proceso similar a la preeclampsia-, con más posibilidad de muerte que la mujer no gestante y mayor muerte fetal y prematuridad. Las vacunas iniciales elaboradas en los EE UU y Europa están siendo efectivas en disminuir las infecciones, hospitalizaciones y muertes en los países donde la vacunación ha avanzado más rápido. Está siendo administrada en gestantes sin efectos secundarios mayores, recomendándoseles se vacunen para evitar la infección severa. Mientras tanto, no se conoce la duración de la inmunidad dada por la infección COVID-19 y por la vacuna. Se está considerando una tercera dosis de refuerzo y el cambio de marca en los vacunados. Y se está en espera de una tercera ola de infecciones debido a la aparición de las variantes brasilera e india (delta).

The SARS-CoV-2 virus continues to reproduce rapidly and is showing more infectious variants. The second wave of the pandemic is subsiding in Europe and the United States of North America, but not in South America. In Peru, the number of deaths has more than doubled, with a higher mortality rate in men and in those over 70 years of age. It has been corroborated worldwide that pregnant women suffer a more severe disease -sometimes with a process similar to preeclampsiawith a greater possibility of death than non-pregnant women and greater fetal death and prematurity. Initial vaccines developed in the USA and Europe are proving effective in reducing infections, hospitalizations and deaths in countries where vaccination has advanced more rapidly. It is being administered in pregnant women without major side effects, and they are recommended to be vaccinated to avoid severe infection. As of now, the duration of immunity given by COVID-19 infection and by the vaccine is not known. A third booster dose and rebranding of vaccinees is being considered. And a third wave of infections is expected due to the emergence of the Brazilian and Indian (Delta) variants.

RESUMEN A finales de 2020 se aprobaron las vacunas desarrolladas en el mundo occidental contra el virus SARS-CoV-2, que ya están siendo inoculadas, conjuntamente con vacunas chinas y rusas. Mientras tanto, estamos en una segunda oleada de la enfermedad y el nuevo coronavirus se ha ido transformando para permitirse una mejor propagación, alojamiento y replicación en el ser humano. La enfermedad se manifiesta ahora con nueva sintomatología, mayor contagio, inclemencia y variación en el número de fallecimientos. La infección de la gestante por coronavirus se está presentando con severidad y consecuencias materno perinatales. Ya se inició la vacunación en gestantes y madres lactantes, previa conversación con su ginecólogo sobre los riesgos y beneficios. Este artículo ofrece un breve relato de los acontecimientos que tuvieron lugar durante la transición de 2020 a 2021.

ABSTRACT In late 2020, vaccines developed in the Western world against the SARS-CoV-2 virus were approved and are currently being inoculated, together with Chinese and Russian vaccines. In the meantime, we are in a second wave of the disease and the new coronavirus has been transforming to allow for better propagation, harboring and replication in humans. The disease now manifests itself with new symptoms, greater contagiousness, severity and variation in the number of deaths. Coronavirus infection of pregnant women is occurring with harshness and maternal and perinatal consequences. Vaccination has been initiated in pregnant women and nursing mothers, after discussion with their gynecologists about risks and benefits.

Resumen ANTECEDENTES: La pandemia mundial de SARS-CoV-2 también afecta a las embarazadas. Los casos más graves ameritan hospitalización y tratamiento en una sala de cuidados intensivos. CASO CLÍNICO: Paciente de 30 años y embarazo con feto único, de 33 semanas, con antecedentes de fibromialgia, un aborto y miomatosis uterina. La paciente negó el contacto con personas sospechosas o infectadas por el virus SARS-CoV-2. El cuadro clínico se inició con infección de las vías respiratorias superiores que evolucionó a neumonía con prueba PCR positiva para COVID-19 a partir del exudado naso-faríngeo, que condicionó el síndrome de insuficiencia respiratoria aguda severa, tratada con asistencia mecánica ventilatoria durante16 días en la unidad de cuidados intensivos. En el trascurso de la hospitalización se complicó con neumotórax bilateral y urosepsis por Candida tropicalis. La paciente superó la enfermedad viral, las complicaciones de la ventilación y la infección urinaria oportunista.

Abstract BACKGROUND: The worldwide SARS-CoV-2 pandemic also affects pregnant women. The most severe cases require hospitalization and treatment in an intensive care unit. CLINICAL CASE: A 30-year-old woman with a 33-week singleton pregnancy and a history of fibromyalgia, one miscarriage and uterine myomatosis. The patient denied contact with persons suspected or infected with SARS-CoV-2 virus. The clinical picture began with upper respiratory tract infection that progressed to pneumonia with positive PCR test for COVID-19 from nasopharyngeal exudate, which led to severe acute respiratory failure syndrome, treated with mechanical ventilation for 16 days in the Intensive Care Unit. During hospitalization, she was complicated with bilateral pneumothorax and urosepsis due to Candida tropicalis. The patient overcame the viral disease, ventilatory complications and the opportunistic urinary tract infection.

RESUMEN El siglo XXI se ha caracterizado desde sus inicios por una problemática de salud que ha afectado al mundo y Cuba no ha podido escapar de esta situación. A fines de 2019, se identificó un nuevo coronavirus, denominado coronavirus 2 del síndrome respiratorio agudo severo (SARS-CoV-2), no identificado anteriormente en seres humanos, como la causa del COVID-19.Con el objetivo de caracterizar el comportamiento de los casos deCOVID-19 en la provincia Granma, se realizó un estudio descriptivo, retrospectivo y transversal. Se presenta a los 13 casos confirmados de la COVID-19 en la provincia Granma, entre el 11 de marzo de 2020 y 31 de mayo de 2020.Desde el comienzo de la Fase pre-epidémica en Cuba hasta el 31 de mayo de 2020 en la provincia Granma, se habían procesado mil 785 muestras de PCR en tiempo real, resultando positivas el 0,72 %. En el periodo que se describe la tasa de incidencia de la provincia fue de 1,6 por 100 mil habitantes. Predominó ligeramente el sexo masculino con 53,8 %, el grupo de edad con mayor incidencia fue el 20 a 49 años con seis casos (45,1 %), la mayoría correspondió a casos que refirieron como fuente de infección el contacto con extranjeros el 54,0 %. Granma en el periodo que se analiza es la provincia con menor riesgo de enfermar por COVID-19 en Cuba. En la serie predominaron: sexo masculino, grupo de edad 20-49 años, fuente de infección contacto con extranjeros y como síntoma, tos seca.

ABSTRACT The 21st century has been characterized from its beginnings by a health problem that has affected the world and Cuba has not been able to escape from this situation. In late 2019, a new coronavirus, called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), previously unidentified in humans, was identified as the cause of COVID-19, with the aim of characterizing the behavior of in the cases of COVID-19 in the Granma province, a descriptive, retrospective and cross-sectional study was carried out. It is presented to the 13 confirmed cases of COVID-19 in the Granma province, between March 11, 2020 and May 31, 2020, from the beginning of the pre-epidemic phase in Cuba until May 31, 2020 in in the Granma province, 1,785 real-time PCR samples had been processed, with 0.72% being positive. In the period described, the incidence rate of the province was 1.6 per 100,000 inhabitants. The male sex predominated slightly with 53.8%, the age group with the highest incidence was 20 to 49 years with six cases (45.1%), the majority corresponded to cases that referred contact with foreigners as the source of infection the 54.0%. Granma in the period analyzed is the province with the lowest risk of becoming ill with COVID-19 in Cuba. The series was dominated by: male sex, age group 20-49 years, source of infection contact with foreigners and as a symptom, dry cough.

El desafío ambiental: enseñanzas a partir de la COVID-19 / The environmental challenge: teachings with COVID-19 as a starting point

Las cuestiones ambientales están ligadas a la emergencia de epidemias. La crisis que enfrenta hoy el mundo ha tenido su origen en las constantes perturbaciones ambientales, lo que se ha reflejado en las preocupaciones manifestadas por la Organización de las Naciones Unidas en cada celebración del Día Mundial del Medio Ambiente. Los ecosistemas degradados no pueden ofrecer servicios ecológicos que garanticen bienestar y salud; así, una crisis lleva a otra. En este artículo se expone cómo al romperse el equilibrio natural que protege al hombre de múltiples riesgos, este queda expuesto a más de un millón de microorganismos patógenos desconocidos que podrían cruzar la barrera de las especies, tal es el caso del nuevo virus SARS-CoV-2; a ello se suma la amenaza del cambio climático, que es un impulsor de muchos riesgos. Los problemas sanitarios estarán siempre sujetos a la interacción de cada civilización con su entorno, lo que depende, en esencia, del carácter de la relación hombre-naturaleza.

The environmental questions are linked to the emergency of epidemics. The crisis that world faces today has had its origin in the constant environmental interferences, what has been reflected in the concerns manifested by the United Nations Organization in each celebration of the Environment World Day. The degraded ecosystems cannot offer ecological services that guarantee well-being and health; this way, a crisis takes to another. In this work it is exposed how men are exposed to more than a million of unknown pathogens microorganisms that could cross the barrier of the species when breaking the natural balance that protects him of multiple risks, such is the case of the SARS-CoV-2 new virus; this comes on top of the threat of the climatic change that is an instigator of many risks. Health problems will always be subject to the interaction of each civilization with their environment, what depends, in essence, of the character in man-nature relationship.

Novel epitope based peptides for vaccine against SARS-CoV-2 virus: immunoinformatics with docking approach

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative viral strain for the contagious pandemic respiratory illness in humans which is a public health emergency of international concern. There is a desperate need for vaccines and antiviral strategies to combat the rapid spread of SARS-CoV-2 infection.Methods: The present study based on computational methods has identified novel conserved cytotoxic T-lymphocyte epitopes as well as linear and discontinuous B-cell epitopes on the SARS-CoV-2 spike (S) protein. The predicted MHC class I and class II binding peptides were further checked for their antigenic scores, allergenicity, toxicity, digesting enzymes and mutation.Results: A total of fourteen linear B-cell epitopes where GQSKRVDFC displayed the highest antigenicity-score and sixteen highly antigenic 100% conserved T-cell epitopes including the most potential vaccine candidates MHC class-I peptide KIADYNYKL and MHC class-II peptide VVFLHVTYV were identified. Furthermore, the potential peptide QGFSALEPL with high antigenicity score attached to larger number of human leukocyte antigen alleles. Docking analyses of the allele HLA-B*5201 predicted to be immunogenic to several of the selected epitopes revealed that the peptides engaged in strong binding with the HLA-B*5201 allele.Conclusions: Collectively, this research provides novel candidates for epitope-based peptide vaccine design against SARS-CoV-2 infection.

Respuesta a diferentes escenarios y complicaciones hematológicas en COVID-19 / Response to different scenarios and hematological complications in COVID-19.

Las enfermedades infecciosas emergentes y reemergentes son desafíos constantes para la salud pública en todo el mundo. Los casos recientes de neumonía de causa desconocida en Wuhan, China, han llevado al descubrimiento de un nuevo tipo de Coronavirus (2019-nCoV), que son virus de Ácido Ribonucleico (RNA) envueltos, de forma común encontrados en humanos, otros mamíferos y aves, capaces de causar enfermedades respiratorias, entéricas, hepáticas y neurológicas 1. La amenaza a la salud de la infección por Coronavirus 2 asociado al SRAS (SARS-CoV-2) y la enfermedad que produce el mismo llamada Enfermedad por Coronavirus (COVID-19) ya está estable- cida con sus tasas de infección y mortalidad de manera considerable más altas si se lo compara con otros virus respiratorios adquiridos en la comunidad 2. En tal sentido es necesario dar una respuesta por parte de la Unidad Técnica de Hematología en relación a esta pandemia con el ánimo de aportar al manejo integral de estos pacientes, homogeneizar criterios clínicos, lidiar de mejor manera con la incertidumbre en el diagnóstico y tratamiento de COVID-19. El SARS CoV-2 y su enfermedad COVID-19, en la mayoría de pacientes tiene una presentación con síntomas leves. Sin embargo, en el 5% de los casos diagnosticados requerirán de una Unidad de Cuidados Intensivos (UCI)3, ya que presentan Síndrome de Dificultad Respiratoria Aguda (SDRA), shock séptico, Insuficiencia Multiorgánica y coagulopatía hemorrágica, así como trombótica, incluyendo Coagulación Intravascular Diseminada (CID), alcanzado en las salas de UCI una tasa mortalidad por COVID-19 entre el 22% al 62% en algunas series 4. Adicional, se ha observado que el grupo de pacientes con mala evolución presentan un estado hiperinflamatorio, asemejándose al cuadro clínico descrito de una linfohistiocitosis hemofagocítica secundaria, que en este caso sería desencadenada por SARS CoV-2 5. Un grupo de Hematólogos de diferentes hospitales de la ciudad de Quito: Especialidades Carlos Andrade Marín-Instituto Ecuatoriano de Seguridad Social (HECAM-IESS), Metropolitano; y, hospitales de la ciudad de Guayaquil: Teodoro Maldonado Carbo-IESS, Hospital Luis Vernaza y Clínica Gilbert, basados en la evidencia científica disponible y experticia profesional, elaboraron éste protocolo con las recomendaciones según los diferentes escenarios y complicaciones hematológicas.

Emerging and reemerging infectious diseases are constant challenges to public health worldwide. Recent cases of pneumonia of unknown cause in Wuhan, China have led to the discovery of a new type of Coronavirus (2019-nCoV), which are enveloped ribonucleic acid (RNA) viruses, commonly found in humans, other mammals, and birds, capable of cause respiratory, enteric, liver and neurological diseases 1. The health threat of SARS-associated coronavirus 2 (SARS-CoV-2) and the disease that produces it called COVID-19 has already been established with its considerably higher infection and mortality rates compared to other respiratory viruses acquired in the community 2. In this sense, it is necessary to give a response from the Hematology Technical Unit in relation to this pandemic in order to contribute to the comprehensive management of these patients, homogenize clinical criteria, better deal with uncertainty in the diagnosis and treatment of COVID-19. SARS CoV-2 and its disease COVID-19, in the majority of patients have a presentation with mild symptoms. However, in 5% of diagnosed cases they will require an Intensive Care Unit (ICU) 3, since they present Acute Respiratory Distress Syndrome (ARDS), septic shock, Multiple Organ Failure and hemorrhagic coagulopathy, as well as thrombotic, including Coagulation Disseminated Intravascular (DIC), achieved in the ICU wards a mortality rate for COVID-19 between 22% and 62% in some series 4. Additionally, it has been observed that the group of patients with poor evolution present a hyperinflammatory state, resembling the clinical picture of secondary hemopha- gocytic lymphohistiocytosis, which in this case would be triggered by SARS CoV-2 5. The group of Hematologists from the hospitals of the city of Quito: Specialties Carlos Andrade Marín HECAM-IESS, Metropolitano; and, hospitals in the city of Guayaquil: Teodoro Maldonado Carbo-IESS, Luis Vernaza Hospital and Gilbert Clinic, based on the available scientific evidence and professional expertise, prepared this protocol with the recommendations according to the different hematological scenarios and complications.

Cirugía durante la pandemia del SARS-COV-2 / COVID-19: el efecto de la generación de aerosoles de partículas en escenarios quirúrgicos / Surgery during the SARS-COV-2 / COVID-19 pandemic: the effect of particle aerosol generation on surgical scenarios

Hasta el momento no se ha publicado información conclusiva que respalde la teoría de que los virus respiratorios se transmitan a través del humo quirúrgico o el neumoperitoneo. Por lo tanto, las alertas sobre los riesgos de la laparoscopia emitidas durante las primeras semanas de la pandemia deben ser analizadas con precaución y a la luz de la evidencia cambiante sobre el tema. Tanto la cirugía abierta como la laparoscópica tienen el potencial de generar aerosoles de partículas y por lo tanto, en ambos escenarios es fundamental la protección de todo el equipo de trabajo dentro del quirófano. En todos los procedimientos durante la época de pandemia, se deben buscar las estrategias más efectivas para controlar las potenciales fuentes de trasmisión y minimizar la exposición del personal en los momentos de mayor riesgo, relacionados con el manejo de la vía aérea y las cavidades del paciente. La siguiente es una revisión narrativa de literatura sobre las cirugías durante la pandemia del SARS-CoV-2 / COVID-19 y el efecto de los aerosoles durante estos procedimientos, con el fin de integrar y dar a conocer las principales medidas que se han propuesto a nivel global, para manejar este nuevo grupo de pacientes

To date no conclusive information has been published to support the theory that respiratory viruses are transmitted through surgical smoke or pneumoperitoneum. Therefore, alerts about the risks of laparoscopy issued during the first weeks of the pandemic should be viewed with caution and in light of changing evidence on the subject. Both open and laparoscopic surgery have the potential to generate aerosols of particles and therefore, in both scenarios, the protection of all the surgical team within the operating room is essential. In all procedures during the pandemic season, the most effective strategies should be sought to control potential sources of transmission and minimize staff exposure at times of greatest risk related to the management of the patient's airway and cavities. The following is a narrative review of the literature on surgeries during the SARS-CoV-2 / COVID-19 pandemic and the effect of aerosols during these procedures, in order to integrate and publicize the main measures that have been proposed globally, to manage this new group of patients
