Role of the one-minute sit-to-stand test in the diagnosis of post COVID-19 condition: a prospective cohort study.

OBJECTIVE: To analyze the relationship between one-minute sit-to-stand test (1MSTST) parameters and a diagnosis of post COVID-19 condition in a cohort of patients who previously had COVID-19. METHODS: This was a prospective cohort study of patients with post COVID-19 condition referred for body plethysmography at a tertiary university hospital. Post COVID-19 condition was defined in accordance with the current WHO criteria. RESULTS: Fifty-three patients were analyzed. Of those, 25 (47.2%) met the clinical criteria for post COVID-19 condition. HR was lower in the patients with post COVID-19 condition than in those without it at 30 s after initiation of the 1MSTST (86.2 ± 14.3 bpm vs. 101.2 ± 14.7 bpm; p < 0.001) and at the end of the test (94.4 ± 18.2 bpm vs. 117.3 ± 15.3 bpm; p < 0.001). The ratio between HR at the end of the 1MSTST and age-predicted maximal HR (HRend/HRmax) was lower in the group of patients with post COVID-19 condition (p < 0.001). An HRend/HRmax of < 62.65% showed a sensitivity of 78.6% and a specificity of 82.0% for post COVID-19 condition. Mean SpO2 at the end of the 1MSTST was lower in the patients with post COVID-19 condition than in those without it (94.9 ± 3.6% vs. 96.8 ± 2.4%; p = 0.030). The former group of patients did fewer repetitions on the 1MSTST than did the latter (p = 0.020). CONCLUSIONS: Lower SpO2 and HR at the end of the 1MSTST, as well as lower HR at 30 s after initiation of the test, were associated with post COVID-19 condition. In the appropriate clinical setting, an HRend/HRmax of < 62.65% should raise awareness for the possibility of post COVID-19 condition.

[The Impact of the COVID-19 Pandemic on the Healthcare System and on the Mental Health of Primary Health Care Providers]. / Repercussão da Pandemia de COVID-19 nos Serviços de Saúde e na Saúde Mental dos Profissionais dos Cuidados de Saúde Primários.

INTRODUCTION: The COVID-19 pandemic forced the reorganization of primary health care services. The aim of this study was to describe how the health services responded to organizational requests; how the health services involved and supported their employees; how professionals perceived their involvement in the procedures and what support was provided to them. Additions aims included assessing the levels of anxiety and depression of professionals and their association with the perceived support, availability of personal protective equipment and involvement in pandemic-related tasks. MATERIAL AND METHODS: Cross-sectional, analytical study directed at professionals from three health center groups using an online questionnaire. We collected information from sociodemographic data, access to personal protective equipment, perceived support, workload and levels of anxiety and depression. Between each variable and the levels of anxiety and depression, multivariate logistic regression was applied. RESULTS: There were responses from 237 professionals (83.8% women; mean age 43.7 years; 43.2% physicians). Almost 60% worked with COVID-19 patients. The availability of personal protective equipment in March versus June 2020 increased (17.7% vs 55.3%). There was a risk management plan in 86% of the workplaces. A high workload (90%) and time pressure (74.6%) were identified. Physicians and nurses had a higher prevalence of depression associated with workload and fatigue (p < 0.001). Protective anxiety factors were having space to talk about problems, support in face of these problems and having a place to relax in the health unit. A lower risk of depression was found in the administrative staff group, in those who felt supported, and in those who actively participated in the contingency plans. CONCLUSION: The COVID-19 pandemic led to considerable changes in the dynamics of primary health care. The time pressure to carry out tasks and the level of concentration required were associated with a higher risk of mental disease. The support felt by healthcare professionals regarding their problems and concerns and the existence of places to relax in the health units were identified as protective factors. Health promotion, the maintenance of the social contacts of healthcare professionals and their involvement in the processes should be taken into account in the organizational dynamics of the institutions.

Introdução: A pandemia de COVID-19 forçou a reorganização dos serviços dos cuidados de saúde primários. Com este estudo pretendemos descrever como responderam os serviços de saúde às solicitações organizacionais, como envolveram e apoiaram os seus colaboradores; como os profissionais percecionaram o seu envolvimento nos procedimentos e que apoio lhes foi fornecido. Pretendemos também avaliar os níveis de ansiedade e depressão dos profissionais e a sua associação não só com o apoio sentido pelos profissionais, mas também com a disponibilidade de equipamentos de proteção individual e com o seu envolvimento nas tarefas relacionadas com a pandemia.Material e Métodos: Estudo transversal analítico dirigido aos profissionais de três agrupamentos de centros de saúde usando um questionário online. Colhemos dados sociodemográficos, informação sobre o acesso a equipamento de proteção individual, apoio percecionado, carga de trabalho e níveis de ansiedade e depressão. Entre cada variável e os níveis de ansiedade e depressão aplicou-se regressão logística multivariada.Resultados: Responderam 237 profissionais (83,8% mulheres; idade média 43,7 anos; 43,2% de médicos). Quase 60% trabalhou com doentes COVID-19. A disponibilidade de equipamento de proteção individual em março versus junho de 2020 aumentou (17,7% vs 55,3%). Existia plano de gestão do risco em 86% dos locais. Identificou-se uma alta carga de trabalho (90%) e pressão do tempo (74,6%). Médicos e enfermeiros apresentavam maior prevalência de depressão associada à carga de trabalho e fadiga (p < 0,001). Ter espaço para falar dos problemas, apoio sentido perante esses problemas e dispor na unidade de saúde de um espaço para relaxar foram alguns fatores protetores de ansiedade. Foi encontrado menor riso de depressão no grupo do secretariado clínico, nos profissionais que se sentiram apoiados, e nos que tiveram participação ativa nos planos de contingência.Conclusão: A pandemia de COVID-19 levou a grandes alterações na dinâmica dos CSP. A pressão do tempo para realização de tarefas e a concentração exigida associaram-se a maior risco de desenvolvimento de patologia mental. O apoio sentido pelos profissionais perante os seus problemas e preocupações, e a existência de espaços para relaxar nas USF foram identificados como fatores protetores. A promoção da saúde, a manutenção dos contactos sociais dos profissionais e o seu envolvimento nos processos deverão ser tidos em conta na dinâmica organizacional das instituições.

Expert Perspectives on the Management of Alpha 1-Antitrypsin Deficiency.

Alpha 1-antitrypsin deficiency is an inherited autosomal codominant disorder, which predisposes patients to lung and/or liver disease. Even though it is considered rare, it is one of the most frequent genetic disorders worldwide, albeit remaining underdiagnosed. Several organizations and societies, including the Portuguese Society of Pulmonology have been elaborating guidelines and recommendations for the diagnosis and management of alpha 1-antitrypsin deficiency. Nevertheless, some important matters are yet to be included in those, mainly due to lack of robust scientific evidence, and continue to represent a point of discussion. This article reviews some important scientific publications and expresses the perspectives of a group of Portuguese experts regarding the management of alpha 1-antitrypsin deficiency, namely in terms of the pre and neonatal diagnosis, the impact of the COVID-19 pandemic, the validity of replacement therapy in lung transplant-receiving, and finally, alternative strategies of alpha 1-antitrypsin deficiency treatment to improve the patients' quality of life.

A deficiência de alfa 1-antitripsina é uma doença hereditária autossómica codominante que aumenta a predisposição para o desenvolvimento de doença pulmonar e/ou hepática. Esta doença, embora seja considerada rara, é um dos distúrbios genéticos mais comuns em todo o mundo. Contudo, atualmente ainda constitui uma doença subdiagnosticada. Várias organizações e sociedades, incluindo a Sociedade Portuguesa de Pneumologia, elaboraram recomendações e diretrizes para o diagnóstico e gestão da deficiência de alfa 1-antitripsina. Porém, estes documentos ainda não abordam alguns temas relevantes associados à gestão da deficiência de alfa 1-antitripsina, principalmente devido à falta de robustez na evidência científica, que continuam a representar um ponto de discussão entre a comunidade médica. Neste artigo é feita a revisão de publicações científicas relevantes acerca da deficiência de alfa 1-antitripsina, e são descritas as perspetivas de especialistas portugueses sobre a gestão da deficiência de alfa 1-antitripsina, nomeadamente ao nível do diagnóstico pré e neonatal, do impacto da pandemia COVID-19, da validação da terapêutica de aumento em doentes que receberam um transplante pulmonar e, por fim, estratégias alternativas para a melhoria do tratamento da deficiência de alfa 1-antitripsina de modo a promover a qualidade de vida dos doentes.

Reduction of Severe Exacerbations of COPD during COVID-19 Pandemic in Portugal: A Protective Role of Face Masks?

Viral infections are known to be the main trigger for Chronic obstructive pulmonary disease (COPD) exacerbations. Face masks are acknowledged for effective viral aerosol shedding reduction. COVID-19 pandemic generated an opportunity to study the impact of face masks and confinement on droplet transmission diseases, usually implicated in acute exacerbations of COPD (AECOPD). We aimed to evaluate the variation on severe AECOPD (sAECOPD) rate in a Portuguese COPD cohort during the first COVID-19 lockdown and following months. This retrospective self-controlled study enrolled 322 adult patients followed at COPD-specialized consultation in a tertiary hospital from February 2016 to July 2020, of whom 286 met inclusion criteria. Severe AECOPD events were registered from March 2020 (beginning of state of emergency) until July 2020. From 2016 to 2019 there was a mean of 38 patients per year with sAECOPD. During 2020, 11 patients experienced sAECOPD. Over the course of 2020 there was a 73.4% (p < 0.001) decrease in sAECOPD events comparing with previous years' average. After the end of State of Emergency, the rate of sAECOPD events also declined by 74.6% (p < 0.001) comparing with the same timeline of previous years. Results were consistent and statistically significant when comparing 2020 with each of previous years for every period of analysis. Our findings suggest a sustained decrease in the rate of sAECOPD during confinement and in the following months. The widespread use of face mask and social distancing during COVID-19 pandemic may play an important role in preventing the transmission of respiratory infections and consequently reducing sAECOPD.
