O objetivo deste trabalho foi analisar os efeitos do distanciamento social à saúde psicossocial da pessoa idosa no período da pandemia da COVID-19. Metodologia: Estudo revisão integrativa, realizado entre abril e Setembro de 2022, documentos dispo- nível como artigos científicos; ano de publicação 2020 a 2022. Os critérios de exclusão foram artigos de revisão, arquivos do tipo dissertação e teses. A pesquisa incluiu 47 do- cumentos; posteriormente foi realizada leitura crítica e reflexiva dos assim, estabeleceu- se a amostra de 11 artigos. Resultados e Discussão: Mediante todas as medidas tomadas para conter a pandemia, o distanciamento social é a estratégia até então mais eficiente para evitar a disseminação do vírus. Entretanto, as evidências mostram que o mesmo pode trazer prejuízos de natureza psicológica e psicossomática à população, principalmente à população idosa, que é um dos grupos de risco para contágio da doença. Além disso, pode provocar hábitos como o sedentarismo e inatividade física, condições que também são atreladas ao desenvolvimento de doenças físicas, mentais e, consequentemente, ao risco de morte em populações vulneráveis. Conclusão: Trata-se de um fenômeno social com- plexo e que exige atenção das entidades prestadoras de serviço à comunidade idosa, assim como os gestores e familiares. Desse modo, as linhas de cuidado devem se basear nas respostas em rede, que realizam esforços intersetoriais que envolvem políticas públicas de saúde, apoio do estado, assistência social, seguridade e justiça em ação das proteções de direitos, instituídos no Estatuto do Idoso.

The objective of this work was to analyze the effects of social distancing on the psychosocial health of the elderly during the COVID-19 pandemic. Methodology: Integrative review study, carried out between April and September 2022, documents available as scientific articles; year of publication 2020 to 2022. Exclusion criteria were review articles, dissertation and theses type files. The research included 47 documents; later, a critical and reflective reading of the articles was carried out, thus, a sample of 11 articles was established. Results and Discussion: Through all the measures taken to contain the pandemic, social distancing is the most efficient strategy so far to prevent the spread of the virus. However, evidence shows that it can bring psychological and psychosomatic damage to the population, especially the elderly population, which is one of the risk groups for contagion of the disease. In addition, it can cause habits such as physical inactivity and physical inactivity, conditions that are also linked to the development of physical and mental illnesses and, consequently, to the risk of death in vulnerable populations. Conclusion: It is a complex social phenomenon that requires attention from entities providing services to the elderly community, as well as managers and family members. In this way, the lines of care must be based on network responses, which carry out intersectoral efforts that involve public health policies, state support, social assistance, security and justice in action of the protections of rights, established in the Statute of the Elderly.

Efficacy of personal protective equipment to prevent environmental infection of COVID-19 among healthcare workers: a systematic review

BACKGROUND@#Healthcare workers (HCWs) employed personal protective equipment (PPE) during the COVID-19 pandemic, crucial to protecting themselves from infection. To highlight the efficacy of PPE in preventing environmental infection among HCWs, a systematic review was conducted in line with PRISMA guidance.@*METHODS@#A search of the PubMed and Web of Science databases was conducted from January 2019 to April 2021 using pre-defined search terms. Articles were screened by three researchers. The approved papers were read in full and included in this review if relevance was mutually agreed upon. Data were extracted by study design and types of PPEs.@*RESULTS@#47 of 108 identified studies met the inclusion criteria, with seven reviews and meta-analyses, seven cohort, nine case-control, fifteen cross-sectional studies, four before and after, four case series, and one modeling studies. Wearing PPE offered COVID-19 protection in HCWs but required adequate training. Wearing surgical masks provided improved protection over cloth masks, while the benefit of powered air-purifying respirators is less clear, as are individual gowns, gloves, and/or face shields.@*CONCLUSIONS@#Wearing PPE, especially facial masks, is necessary among HCWs, while training in proper use of PPE is also important to prevent COVID-19 infection.

Preliminary Recommendations on the Timing of Lung Surgery after Novel Coronavirus Infection in Patients with Pulmonary Nodules and Lung Cancer / 中国肺癌杂志

In recent years, the corona virus disease 2019 (COVID-19) pandemic has had a huge impact on the global medical, political and economic fields. Since the beginning of the COVID-19 epidemic, our understanding of the impact of COVID-19 has grown exponentially. Recently, the COVID-19 epidemic has changed rapidly in China, and there has been controversy over how to carry out surgical operations for patients with lung neoplastic lesions. Some studies have shown that lung cancer patients undergoing surgery are more likely to experience respiratory failure and perioperative death after contracting COVID-19 than the general population, however, delays in cancer treatment are also associated with increased mortality among these patients. In particular, the novel coronavirus Omikron variant has a higher transmissibility and may escape the immunity obtained through the previous novel coronavirus infection and vaccination. In order to minimize the risk of novel coronavirus infection in surgical patients, it is necessary to develop new treatment guidelines, expert consensus and preventive measures. However, the current rapid change of the epidemic situation has led to insufficient time and evidence to develop guidelines and consensus. Therefore, thoracic surgeons need to evaluate specific patient populations at higher risk of severe complications before surgery and weigh the benefit of surgical treatment against the risk of novel coronavirus infection. We try to give some recommendations on lung surgery during the current domestic epidemic situation based on the guidelines and consensus of oncology and thoracic surgery organizations in different regions on lung surgery.

Perinatal and neonatal management plan for prevention and control of SARS-CoV-2 infection (3rd Edition) / 中国当代儿科杂志

Since the global pandemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in 2020, the virus has been evolving through mutations to acquire enhanced infectivity but reduced virulence. With a wide vaccination coverage among Chinese population, China is entering a new stage of SARS-CoV-2 infection control. The Working Group for the Prevention and Control of Neonatal SARS-CoV-2 Infection in the Perinatal Period of the Editorial Committee of Chinese Journal of Contemporary Pediatrics released the first and second editions of perinatal and neonatal management plan for prevention and control of SARS-CoV-2 infection in January and March 2020, respectively. In order to follow up new prevention and control needs, it is necessary to update the management plan to better guide clinical practice. Therefore, the Working Group formulated the 3rd-edition plan.

Host protection against Omicron BA.2.2 sublineages by prior vaccination in spring 2022 COVID-19 outbreak in Shanghai / 医学前沿

The Omicron family of SARS-CoV-2 variants are currently driving the COVID-19 pandemic. Here we analyzed the clinical laboratory test results of 9911 Omicron BA.2.2 sublineages-infected symptomatic patients without earlier infection histories during a SARS-CoV-2 outbreak in Shanghai in spring 2022. Compared to an earlier patient cohort infected by SARS-CoV-2 prototype strains in 2020, BA.2.2 infection led to distinct fluctuations of pathophysiological markers in the peripheral blood. In particular, severe/critical cases of COVID-19 post BA.2.2 infection were associated with less pro-inflammatory macrophage activation and stronger interferon alpha response in the bronchoalveolar microenvironment. Importantly, the abnormal biomarkers were significantly subdued in individuals who had been immunized by 2 or 3 doses of SARS-CoV-2 prototype-inactivated vaccines, supporting the estimation of an overall 96.02% of protection rate against severe/critical disease in the 4854 cases in our BA.2.2 patient cohort with traceable vaccination records. Furthermore, even though age was a critical risk factor of the severity of COVID-19 post BA.2.2 infection, vaccination-elicited protection against severe/critical COVID-19 reached 90.15% in patients aged ≽ 60 years old. Together, our study delineates the pathophysiological features of Omicron BA.2.2 sublineages and demonstrates significant protection conferred by prior prototype-based inactivated vaccines.

Use and management of disinfectants by dentists in San Luis Potosi, Mexico, during the covid-19 pandemic / Uso y manejo de desinfectantes por odontólogos de San Luis Potosí, México durante la pandemia covid-19

Introduction: Chlorine, ethyl alcohol, and quaternary ammonium are disinfectants with antiviral activity against SARS-Cov2. However, there are no previous reports of their use and handling for cleaning and disinfection in dental offices. Objetive: To determine the use and management of disinfectants in critical and non-critical areas used by dentists in San Luis Potosí, Mexico, during the COVID-19 pandemic. Material and Methods: A validated cross-sectional survey was applied online to 100 dentists in San Luis Potosí between February and June 2021. Participants were informed about the handling of personal data according to the standard DOF regulations (DOF 07-05-2010). Results: A total of 100 dentists were included in the study, 63% female and 37% male, with a mean age of 26 years. The most widely used disinfectants during the pandemic in critical areas were Lysol® and 0.1% sodium hypochlorite in non-critical areas. Eighty-five percent of dentists know the adverse effects of inappropriate use of disinfectants, 72% did not have any sign or symptom associated with the use of disinfectants. The most used protection barrier was gloves (97%). Sixty-seven per cent of dentists disposed of disinfectant waste down the drain. Conclusion: Sodium hypochlorite and quaternary ammonium compounds and/or ethanol are used to clean non-critical and critical areas in dental offices. However, appropriate measures for their management are not adopted. It is necessary to implement educational strategies to improve the use and management of disinfectants in dental practice.

Plantas com ação no sistema nervoso central que constam na relação nacional de plantas medicinais de interesse ao sus (RENISUS) / Plants acting on the central nervous system: review plantas com ação no sistema nervoso central que constam na relação nacional de plantas medicinais de interesse ao sus (RENISUS) / Plantas con acción sobre el sistema nervioso central incluidas en la lista nacional de plantas medicinales de interés para sus (RENISUS)

A depressão é uma doença grave que atinge a população em geral, estudos epidemiológicos estimam que a prevalência da depressão ao longo da vida no Brasil está em torno de 15,5%. Os fatores que desencadeiam o aparecimento da depressão incluem fatores sociais, psicológicos, biológicos e também fatores externos específicos como eventos estressantes, solidão, consumo de álcool e drogas, doenças crônicas e dar á luz (depressão pós-parto). O objetivo da presente pesquisa consistiu em realizar uma revisão bibliográfica sobre as principais plantas medicinais com ação antidepressiva. A ansiedade vem se tornando um dos principais problemas da atualidade, sendo intensificada pela pandemia causada pelo coronavírus, onde constatou-se que durante o pico da pandemia onde os casos confirmados de COVID-19 no Brasil ascenderam de 45.757 para 330.890, e as mortes, de 2.906 para 21.048, o sentimento de tristeza/depressão atingiu 40% dos adultos brasileiros. Os sintomas de depressão podem ser amenizados quando a disponibilidade sináptica de monoaminas são aumentadas, e esse aumento pode ocorrer através da diminuição da metabolização desses neurotransmissores. Neste sentido, busca-se através da farmacoterapia a utilização de antidepressivos que disponibilizem as monoaminas na fenda sináptica. A escolha do fármaco é feita com base nos sintomas da depressão e na boa resposta a uma determinada classe de antidepressivos. Em fevereiro de 2009 o Ministério da saúde lançou a Relação Nacional de Plantas Medicinais de Interesse ao SUS (RENISUS), contendo 71 espécies vegetais que são distribuídas de forma in natura nas unidades básicas de saúde (UBS). Destas, somente três espécies apresentam efeito antidepressivo e ansiolítico comprovados na literatura sendo Matricharia chamomilla, Erytrinum mulungu e a Passiflora incarnata que também fazem parte da RENISUS. Além destas, outras espécies como a Melissa officinalis, Lippia alba, Valeriana officinalis e Piper methysticum são utilizadas pela população para tratar ansiedade, insônia e depressão, sugerindo desta forma que estas espécies sejam incluídas na RENISUS.

Depression is a serious disease that affects the general population, epidemiological studies estimate that the prevalence of depression throughout life in Brazil is around 15.5%. The factors that trigger the onset of depression include social, psychological, biological and also specific external factors such as stressful events, loneliness, alcohol and drug consumption, chronic diseases and giving birth (postpartum depression). The objective of the present research was to carry out a literature review on the main medicinal plants with antidepressant action. Anxiety has become one of the main problems of today, being intensified by the pandemic caused by the coronavirus, where it was found that during the peak of the pandemic where confirmed cases of COVID-19 in Brazil rose from 45,757 to 330,890, and deaths, from 2,906 to 21,048, the feeling of sadness/depression reached 40% of Brazilian adults. Symptoms of depression can be alleviated when synaptic availability of monoamines is increased, and this increase can occur through decreased metabolization of these neurotransmitters. In this sense, the use of antidepressants that make monoamines available in the synaptic cleft is sought through pharmacotherapy. The choice of drug is based on symptoms of depression and good response to a particular class of antidepressants. In February 2009, the Ministry of Health launched the National List of Medicinal Plants of Interest to the SUS (RENISUS), containing 71 plant species that are distributed in natura form in basic health units (UBS). Of these, only three species have antidepressant and anxiolytic effects proven in the literature, being Matricharia chamomilla, Erytrinum mulungu and Passiflora incarnata, which are also part of RENISUS. In addition to these, other species such as Melissa officinalis, Lippia alba, Valeriana officinalis and Piper methysticum are used by the population to treat anxiety, insomnia and depression, thus suggesting that these species are included in RENISUS.

Los estudios epidemiológicos estiman que la prevalencia de la depresión a lo largo de la vida en Brasil es de alrededor del 15,5%.

Los síntomas de la depresión pueden aliviarse cuando se aumenta la disponibilidad sináptica de las monoaminas, y este aumento puede producirse mediante una disminución de la metabolización de estos neurotransmisores. En este sentido, se busca a través de la farmacoterapia el uso de antidepresivos que hagan disponibles las monoaminas en la hendidura sináptica. La elección del fármaco se hace en función de los síntomas de la depresión y de la buena respuesta a una clase concreta de antidepresivos. En febrero de 2009, el Ministerio de Salud lanzó la Lista Nacional de Plantas Medicinales de Interés para el SUS (RENISUS), que contiene 71 especies de plantas que se distribuyen in natura en unidades básicas de salud (UBS). De ellas, sólo tres especies tienen efectos antidepresivos y ansiolíticos probados en la literatura: Matricharia chamomilla, Erytrinum mulungu y Passiflora incarnata, que también forman parte del RENISUS.

Review Covid-19 (sars-cov-2) and medicinal plants ­ literature / Revisão Covid-19 (sars-cov-2) e plantas medicinais - literatura / Revisión Covid-19 (sars-cov-2) y plantas medicinales - bibliografía

In December 2019, a new coronavirus originating from the city of Wuhan in China started an epidemic that brought many countries into chaos and despair. SARS-CoV-2, as identified, gave rise to the severe acute respiratory syndrome called COVID-19. Its transmission happens through droplets of saliva, hand or contaminated surfaces. Since its discovery, COVID-19 has led many to death, therefore, researchers from around the world have joined efforts to develop strategies to contain the virus. In this race, drugs such as Chloroquine and Hydroxychloroquine have become possible options for showing an antiviral effect, however, studies contest their efficiency, generating uncertainties. Therefore, other alternatives have been investigated in this context, and the study of medicinal plants has been the target of research for the treatment of COVID-19 in search of bioactive natural products that can exert an antiviral action. The study aimed to analyze the published literature on COVID-19 (SARS-CoV-2) and its relationship with medicinal plants. Bibliographical survey. So far, no specific treatment against the disease has been found, only supportive, with drugs that aim to improve the individual's immune system and ensure that the virus does not replicate, for example, there are options such as chloroquine, hydroxychloroquine, remdesivir and convalescent plasma. On the other hand, studies have revealed that medicinal plants such as garlic, among others, showed efficiency in modulating proteins with a view to preventing viral replication and improving immunity against COVID-19. So far, there are no drugs that are completely safe and have been shown to have activity against the new coronavirus (SARS-CoV-2). However, medicinal plants can contribute to the development of specific therapies against SARS-CoV-2 in a safe and effective way.

O estudo teve como objetivo analisar a literatura publicada sobre COVID-19 (SARS-CoV-2) e sua relação com plantas medicinais. Levantamento bibliográfico. Até o momento, não foi encontrado nenhum tratamento específico contra a doença, apenas de suporte, com medicamentos que visam melhorar o sistema imunológico do indivíduo e garantir que o vírus não se replique, por exemplo, há opções como cloroquina, hidroxicloroquina, remdesivir e convalescença plasma. Por outro lado, estudos revelaram que plantas medicinais como o alho, entre outras, mostraram eficiência na modulação de proteínas visando prevenir a replicação viral e melhorar a imunidade contra a COVID-19. Até o momento, não existem medicamentos completamente seguros e que tenham demonstrado atividade contra o novo coronavírus (SARS-CoV-2). No entanto, as plantas medicinais podem contribuir para o desenvolvimento de terapias específicas contra o SARS-CoV-2 de forma segura e eficaz.

Durante el período prepandémico los motivos de testeo fueron control de salud 47,6% (n=225) y situaciones de riesgo/síntomas 52,4% (n=248), mientras que en el período pandémico fueron control de salud 27,5% (n=38) y situaciones de riesgo/síntomas 72,5% (n=100) respectivamente, p=0.0001. Tests positivos: 5,7% (n=27) vs. 8,7% (n=12), p=0.28. Las medianas de recuento de linfocitos T CD4+ y carga viral fueron: 327 cel/uL (135-718) y 66300 copias/mL (5260-192000), sin diferencias significativas.Conclusiones: La cantidad de testeos realizados durante la pandemia corresponde a un tercio de los realizados durante el período previo, con un descenso en aquellos motivados por controles de salud, evidenciando el impacto de la pandemia en el diagnóstico de VIH

INTRODUCTION: HIV infection remains as a public health worldwide problem. The restrictions taken during the COVID-19 pandemic could have affected the scope of the 95-95-95 goals proposed by UNAIDS. The aim of this work is to determine the impact of the COVID-19 pandemic on the performance of rapid HIV tests in an Acute General Hospital.METHODS: Retrospective analysis of data from patients over 16 years old, of both sexes, who underwent a rapid HIV test during the COVID-19 pandemic vs. the previous period.RESULTS: Of 611 tests, 473 (77.4%) correspond to the pre-pandemic period and 138 (22.6%) to the pandemic. The median age (interquartile range) was 32 years old (24-40); male sex 386 (63.2%), without significant differences. During the pre-pandemic vs pandemic period, the reasons for testing were: health control 47.6% (n=225) and risk situations/symptoms 52.4% (n=248), vs 27.5% (n= 38) and 72.5% (n=100) respectively, p=0.0001. Positive tests: 5.7% (n=27) vs 8.7% (n=12), p=0.28. The median CD4+ T lymphocyte count and viral load were: 327 cells/uL (135-718) and 66,300 copies/mL (5,260-192,000), with no significant differences.CONCLUSIONS: The number of tests carried out during the pandemic equals to a third of those performed during the previous period, with a decrease in those motivated by health controls; evidencing the impact of the pandemic on the diagnosis of HIV

La infección por vih en tiempos de pandemia: muchos retrocesos, innumerables desafíos / HIV infection in times of pandemic: many setbacks, countless challenges

Resumen Desde la llegada de la pandemia por COVID-19, se ha descrito un sinnúmero de consecuencias respecto a la infección por VIH en Chile, tanto en su diagnóstico como en su prevención, principalmente manifestadas en el descenso de la realización de exámenes serológicos, la interrupción de la atención, el retraso en el inicio de la terapia antirretroviral y la falta de acceso a métodos preventivos. A ello, se le suma el deterioro en algunas condiciones relacionadas con aspectos sociales y sobre salud mental. Todo esto implica, entre otras consecuencias, un probable empeoramiento en la situación epidemiológica de la infección por VIH en Chile. En el presente artículo, se revisarán algunos de los impactos señalados y se plantean algunos desafíos, para el enfrentamiento de esta problemática.

Abstract Since the arrival of the COVID-19 pandemic, countless consequences have been described regarding HIV infection in Chile, both in its diagnosis and prevention, mainly manifested in the decrease in serological tests, the interruption of care, the delay in starting antiretroviral therapy, and the lack of access to preventive methods. Added to this is the deterioration in some conditions related to social aspects and mental health. All this implies, among other consequences, a probable worsening in the epidemiological situation of HIV infection in Chile. Some of the designated impacts are reviewed in this article, and some challenges are raised to confront this problem.

Vigilancia epidemiológica en pandemia de COVID-19: Sistema EPIVIGILA / Epidemiological surveillance in COVID- 19 pandemic: EPIVIGILA system

En marzo 2020 se despliega la primera versión de EPIVIGILA en un ambiente productivo, plataforma de integración tecnológica de vigilancia epidemiológica nacional para enfermedades de notificación obligatoria (a pocos días del caso 1 de COVID- 19 local). Anteriormente, Chile usaba un proceso manual que probablemente hubiese fracasado ante un volumen máximo superior a 38 000 notificaciones diarias, en un país con 18 millones de habitantes, de geografía larga y angosta y gobernanza centralizada. El objetivo del trabajo es relevar la importancia que tiene en el manejo de la pandemia el sistema nacional de vigilancia electrónico EPIVIGILA. La principal fortaleza del sistema es su capacidad de adaptación a las necesidades de información fidedigna, precisa, oportuna y en tiempo real. EPIVIGILA fue capaz de incluir, en el curso de las circunstancias, distintos flujos, actores, datos y funcionalidades con altas expectativas de exactitud. Ello permitió que las autoridades pudieran evaluar el impacto de las medidas implementadas para el manejo y control de la pandemia. Su versatilidad posiciona a esta plataforma entre las pocas en el mundo que opera datos nacionales en una pandemia con un alto nivel de granularidad en un único sistema. En Chile, EPIVIGILA es la principal fuente de información para los reportes diarios, informes epidemiológicos y datos publicados en sitios web gubernamentales sobre COVID- 19. Así, el uso de sistemas electrónicos muestran ser un soporte fundamental para la salud pública, porque el registro y procesamiento de los datos genera información clara, confiable y oportuna, contribuyendo a que las autoridades puedan tomar decisiones orientadas a disminuir la propagación de enfermedades transmisibles, evitar muertes y mejorar la calidad de vida de la población.

In March 2020, the first version of EPIVIGILA was deployed in a productive environment a few days after the first local case of COVID- 19. This system is a technological integration plat-form for national epidemiological surveillance of notifiable diseases. Previously, Chile used a manual process that would probably have failed with a peak volume of more than 38 000 daily notifications; in a country with 18 million inhabitants, long and narrow geography, and centralized governance. This work highlights the importance of the national electronic surveillance system ­ EPIVIGILA ­ in managing the pandemic. The system's main strength is its ability to adapt to the needs of reliable, precise, timely, and real- time information. EPIVIGILA was able to include, under the circumstances, different flows, actors, data, and functionalities with high expectations of accuracy. This valuable information allowed the authorities to assess the impact of the measures to manage and control the pandemic. Its versatility positions this platform among the few globally that operates national data with a high level of granularity in a single system through a pandemic. In Chile, EPIVIGILA is the primary source of information for daily reports, epidemiological reports, and data published on government websites about COVID- 19. Thus, electronic systems prove fundamental for public health because the recording and processing of data generate clear, reliable, and timely information, helping authorities make decisions to reduce the spread of infectious diseases, prevent deaths, and improve the population's quality of life.

Manifestaciones Gastrointestinales de COVID-19: puesta al día y revisión de literatura / Gastrointestinal Manifestations of COVID-19: update and literature review

The Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a single-stranded RNA virus belonging to the beta coronavirus family, it is the cause of the COVID-19 disease and the pandemic that has revolutionized and challenged the medical research profession and health systems around the world. With the first coronavirus SARS-CoV, the important role of the angiotensin 2-converting enzyme (ACE2) in the pathophysiology of the disease caused by the virus was discovered, a discovery that would lay the foundations on which research on the new coronavirus is based. The virus is capable of producing disease with a wide spectrum of clinical presentation, from asymptomatic patients to patients with severe acute respiratory distress syndrome (ARDS) requiring admission to intensive care units (ICU). The most commonly described symptoms are fever, cough, myalgia, and dyspnea. However, and with advances in the knowledge of SARS-CoV-2 infection, it has been discovered that gastrointestinal (GI) symptoms are frequent and have been associated with severe disease. Viral RNA has been found in feces, urine, blood, and other fluids, which could mean that there are other routes of infection that have not been considered a threat by the medical community until now. In this article, an updated bibliographic review of this topic is presented, with articles selected from the PubMed platform.

Aprendizaje colaborativo en la plataforma WhatsApp y el teléfono celular en tiempos de pandemia / Collaborative learning in the WhatsApp platform and the cellphone during pandemic times

Introducción: La pandemia COVID-19, causada por el virus SARS-CoV-2, y su exponencial crecimiento y migración a todos los continentes del globo terráqueo, provocaron una parálisis en el proceso de enseñanza-aprendizaje en las instituciones que no contaban con infraestructura en línea para el desarrollo de las actividades docentes de manera virtual. Objetivo: Exponer los retos, las soluciones y los aprendizajes que formaron parte del proceso para preservar las discusiones de casos clínicos en grupos pequeños de estudiantes durante las fases de cuarentena obligatoria de la pandemia en Sudáfrica. Métodos: Se aplicaron las fases de la investigación-acción adaptadas a las prácticas educacionales. En su ejecución participaron los 103 estudiantes del segundo año del grado de bachiller en Medicina y Cirugía, y sus 10 tutores. El módulo de Neurociencias fue el contexto educativo en el período comprendido entre abril y julio de 2020. Resultados: Se crearon chats de comunicación entre los actores del proceso. El módulo se prolongó en duración, y flexibilizó la frecuencia y el horario de las tutorías. Se redujo el número de secciones a develar de los casos y en cada una se introdujeron tareas que guiaron a aplicar contenidos derivados de los objetivos de aprendizaje. Se escogió la aplicación WhatsApp como la plataforma donde se realizarían las sesiones de tutoría. Conclusiones: El desplazamiento del aprendizaje colaborativo de las tutorías a la aplicación WhatsApp convirtió a esta plataforma en un aula virtual accesible en áreas de pobre conectividad. Los reajustes en la extensión y duración de los casos, y las nuevas tareas en sus secciones, se adaptaron a un proceso de asimilación más lento y con más opciones de mediación. Múltiples y variados resultaron los aprendizajes para los actores del proceso; vale destacar el humano y el tecnológico.

ABSTRACT Introduction: The COVID-19 pandemic, caused by the coronavirus SARS-CoV-2, as well as its exponential growth and migration to all continents of the globe, caused a paralysis in the teaching-learning process in institutions that did not have online infrastructure for the development of virtual teaching activities. Objective: To expose the challenges, solutions and learning that were part of the process for preserving clinical case discussions in small groups of students during the mandatory quarantine phases of the pandemic in South Africa. Methods: Action research phases adapted to educational practices were applied. All 103 second-year Bachelor of Medicine and Surgery students and their ten tutors participated in its execution. The Neurosciences module was the educational context in the period from April to July 2020. Results: Communication chats were created between the actors of the process. The module was extended in length, and the frequency and schedule of tutoring sessions was made more flexible. The number of sections to be unveiled from the cases was reduced; each section included guiding tasks for applying contents derived from the learning objectives. The WhatsApp application was chosen as the platform where the tutoring sessions would take place. Conclusions: The shift of collaborative learning from tutorials to the WhatsApp application turned this platform into a virtual classroom accessible in areas of poor connectivity. The length readjustments in the cases, as well as the new tasks in their sections, were adapted to a slower assimilation process and with more mediation options. There were multiple and varied learning experiences for the actors in the process; it is worth highlighting the human and technological aspects.

Impacto da pandemia do COVID-19 na vacinação de crianças de até um ano de idade: um estudo ecológico / Impact of the COVID-19 pandemic on the vaccination of children 12 months of age and under: an ecological study

Resumo O objetivo do estudo foi avaliar o impacto da pandemia de COVID-19 nos valores de vacinação para as imunizações voltadas a indivíduos com menos de um ano de vida no Brasil. Analisou-se os valores de cobertura vacinal, em território nacional, de dez vacinas presentes no calendário do Programa Nacional de Imunizações (PNI) durante os últimos oito anos (2013-2020). Esse é um estudo ecológico e todos os dados foram extraídos do PNI. Comparativamente aos anos prévios, em 2020 registrou-se o menor valor de cobertura vacinal da média do conjunto das vacinas estudadas, 75,07%, enquanto em 2019 esse mesmo índice ficou em 84,44%, resultando em uma queda de 11,10% entre esses dois períodos. Além disso, no ano da pandemia, das dez vacinas analisadas, nove registraram o seu menor valor histórico de cobertura, todas estando a no mínimo 14 pontos percentuais abaixo da meta do Ministério da Saúde. Embora já houvesse uma tendência de queda na cobertura vacinal, por diversos motivos, o presente estudo demonstra que os valores registrados em 2020 foram significativamente menores, fenômeno também registrado em outros países. Portanto, mesmo não conseguindo afirmar que a pandemia de COVID-19 e as medidas de distanciamento sejam as causas da queda dos valores de imunização, podemos inferir que há uma associação.

Abstract This study aimed to evaluate the impact of the COVID-19 pandemic on the vaccination numbers for immunization geared toward individuals under 12 months of age in Brazil. This study analyzed the numbers of the nationwide vaccination coverage of ten vaccines present in the calendar from the National Immunization Program (NIP) over the past eight years (2013-2020). This is an ecological study, and all data were taken from the NIP. In comparison to the previous years, 2020 recorded the lowest figures of vaccination coverage (VC) of the average of the group of studied vaccines - 79.07% - while in 2019, this same index was 84.44%, resulting in a drop of 11.10% between these two periods. Moreover, during the year of the pandemic, of the ten analyzed vaccines, nine recorded their lowest historical VC figures, all of which were at least 14 percentage points below the goals set by the Brazilian Ministry of Health (MS, in Portuguese). Although there had already been a tendency toward a decline in VC, for various reasons, the present study illustrates that the numbers recorded in 2020 were significantly lower, a phenomenon also reported in other countries. Therefore, although it is impossible to affirm that the COVID-19 pandemic and its distancing measures are the causes for the drop in the immunization numbers, it can be inferred that there is indeed an association.

Impact of the COVID-19 pandemic on compulsory notification of meningitis during the first wave of the pandemic in Brazil: an ecological study using P-score

Abstract BACKGROUND: Meningitis is listed as one of the diseases requiring compulsory notification in Brazil. It can affect all age groups and also has no seasonality. Cases can be recorded in all months of the year and in all states of Brazil. Despite its importance, the obligation of immediate notification may have been compromised by the coronavirus disease 2019 (COVID-19) pandemic. OBJECTIVE: To analyze the immediate impact of the COVID-19 pandemic on compulsory notifications of meningitis in Brazil and its states during the first wave of the pandemic. DESIGN AND SETTING: This was an ecological study involving all confirmed cases of meningitis in Brazil, in its regions and in its states. METHODS: Data for the months from 2015 to 2020 were obtained from the database of the Notifiable Diseases Information System (Sistema de Informação de Agravos de Notificação, SINAN), in the Department of Informatics of the National Health System (Departamento de Informática do Sistema Único de Saúde, DATASUS). The P-score was used to obtain the percentage change in the numbers of cases reported in 2020. RESULTS: A 45.7% reduction in notifications of meningitis in Brazil was observed. Regarding the regions and the states, with the exception of Roraima, all of them showed a negative P-score, with decreasing curves each month. CONCLUSION: The pandemic caused a negative impact on meningitis notifications in Brazil.
