High prevalence of SARS-CoV-2 detection and prolonged viral shedding in stools: A systematic review and cohort study.

OBJECTIVES: To: 1. Describe the frequency of viral RNA detection in stools in a cohort of patients infected with SARS-CoV-2, and 2. Perform a systematic review to assess the clearance time in stools of SARS-CoV-2. METHODS: We conducted a prospective cohort study in two centers between March and May 2020. We included SARS-CoV-2 infected patients of any age and severity. We collected seriated nasopharyngeal swabs and stool samples to detect SARS-CoV-2. After, we performed a systematic review of the prevalence and clearance of SARS-CoV-2 in stools (PROSPERO-ID: CRD42020192490). We estimated prevalence using a random-effects model. We assessed clearance time by using Kaplan-Meier curves. RESULTS: We included 32 patients; mean age was 43.7±17.7 years, 43.8% were female, and 40.6% reported gastrointestinal symptoms. Twenty-five percent (8/32) of patients had detectable viral RNA in stools. The median clearance time in stools of the cohort was 11[10-15] days. Systematic review included 30 studies (1392 patients) with stool samples. Six studies were performed in children and 55% were male. The pooled prevalence of viral detection in stools was 34.6% (twenty-four studies, 1393 patients; 95%CI:25.4-45.1); heterogeneity was high (I2:91.2%, Q:208.6; p≤0.001). A meta-regression demonstrates an association between female-gender and lower presence in stools (p=0.004). The median clearance time in stools was 22 days (nineteen studies, 140 patients; 95%CI:19-25). After 34 days, 19.9% (95%CI:11.3-29.7) of patients have a persistent detection in stools. CONCLUSIONS: Detection of SARS-CoV-2 in stools is a frequent finding. The clearance of SARS-CoV-2 in stools is prolonged and it takes longer than nasopharyngeal secretions.

The need for changes in medical education and the perception of teachers before the Covid-19 pandemic / Necessidade de mudanças na educação médica e a percepção de professores antes da pandemia da Covid-19 / Necesidad de cambios en la educación médica y la percepción de profesores antes de la pandemia de Covid-19

Este estudo objetiva analisar questões da educação médica evidenciadas pelas medidas de distanciamento social provocadas pela pandemia do coronavírus19 associadas às percepções de professores de medicina sobre esses mesmos aspectos, em um momento prévio à eclosão da crise sanitária. Realizamos um recorte de resultados de uma pesquisa de natureza qualitativa e conduzimos a discussão com base na triangulação de dados entre observações de campo e entrevistas com professores. A pandemia reacendeu debates sobre a relevância de conteúdos, a utilização de tecnologias digitais para fins pedagógicos e o valor do trabalho colaborativo. Além disso, resgatou questões que envolvem habilidades de comunicação e a saúde de estudantes nas práticas do cuidado. Discutiremos a experiência passada articulando-a às experiências recentes e o que poderemos recolher para (re)construirmos os rumos da formação dos médicos.(AU)

El análisis multivariado de los factores clínicos identificó que la edad (RR ajustado [RRa] 1,03; IC 95%: 1,00-1,06, p=0,021), el índice de masa corporal (IMC, RRa 1,03; IC 95%: 1,01-1,05; p=0,006), la HTA (RRa 1,68; IC 95%: 1,09-2,56; p=0,017), el índice de PaO2/FiO2 (RRa 0,99; IC 95%: 0,99-1,00; p<0,001), la exposición a lopinavir/ritonavir (RRa 0,83; IC 95%: 0,76-0,91; p<0,001), y corticoides sistémicos (RRa 1,18; IC 95%: 1,09-1,27; p<0,001) estuvieron asociados a la mortalidad de manera significativa. Conclusiones: la edad, IMC, HTA, índice PaO2/FiO2, y la exposición a corticoides y LPV/r estuvieron asociadas a la mortalidad en pacientes hospitalizados por neumonía por SARS-CoV-2.

ABSTRACT Objective: this study aimed to describe the main factors associated to mortality in a cohort of patients hospitalized with SARS-CoV-2 pneumonia in a public hospital in Lima, Peru. Materials and methods: this was a retrospective cohort study, with a non-random convenience sampling. Adult patients with confirmed/suspicious SARS-CoV-2 pneumonia with rapid and/ or molecular tests were included. Demographic, clinical, laboratory, tomographic and treatment variables were identified. Descriptive statistics, bivariate analysis, and Poisson regression techniques were used to determine the adjusted relative risk (aRR). Results: 122 patients were included, 70.5% were male, with a mean age of 55.8 years, with a history of obesity (25.4%) and high blood pressure (HBP, 13.1%). The multivariate analysis of clinical factors identified that age (aRR 1.03; 95% CI: 1,00- 1.06; p=0.021), body mass index (BMI; aRR 1.03; 95% CI: 1.01-1.05; p=0.006), HBP (aRR 1.68; 95% CI: 1.09-2.56; p=0.017), PaO2/FiO2 index (aRR 0.99; 95% CI: 0.99-1.00; p<0.001), exposure to lopinavir/ritonavir (LPV/r; aRR 0.83; 95% CI: 0.76-0.91; p <0.001), and systemic corticosteroids (aRR 1.18; 95% CI: 1.09-1.27; p<0.001) were significantly associated with mortality. Conclusions : Age, BMI, HBP, PaO2/FiO2 index, and exposure to corticosteroids and LPV/r were associated with mortality in our cohort of patients hospitalized with SARS-CoV-2 pneumonia.

[Emotional impact of the Covid-19 pandemic on healthcare workers in one of the most important infection outbreaks in Europe]. / Impacto emocional de la pandemia de Covid-19 en los trabajadores sanitarios de uno de los focos de contagio más importantes de Europa.

BACKGROUND AND OBJECTIVES: The Covid-19 pandemic has put healthcare professionals around the world in an unprecedented challenge. This may cause some emotional difficulties and mental health problems. The aim of the present study was to analyze the emotional status among the health care workers form the Hospital of Igualada (Barcelona), while they were facing with Covid-19 in one of the most affected regions in all of Europe. PATIENTS AND METHODS: A total of 395 participants were included in the study. A cross-sectional assessment was carried out between the months of March and April. Information about anxiety, depression, and stress was gathered. We also collected demographic data and concerning potentially stressful factors. RESULTS: A significant proportion of professionals reported symptoms of anxiety (31.4%) and depression (12.2%) from moderate to severe intensity. Symptoms of acute stress were reported by 14.5% of participants. We performed a regression analysis, which explained the 30% of the variance associated with the degree of emotional distress (Ry=0.30). The final model reveals that females (or young males), who are working in the frontline as nursing assistants, caretakers or radiology technicians, with the uncertainty of a possible infection, the perception of inadequate protection measures and having experienced the death of a close person by Covid-19, showed a heightened risk of experiencing psychological distress. CONCLUSIONS: Coping with the Covid-19 pandemic caused a significant impact on emotional status of healthcare workers involved in this study.

From the handling of an outbreak by an unknown pathogen in Wuhan to the preparedness and response in the face of the emergence of Covid-19 in Mexico.

On December 31, 2019, the Chinese health authorities informed the international community, through the mechanisms established by the World Health Organization (WHO), of a pneumonia epidemic of unknown etiology in Wuhan, Hubei Province. The first cases were reported early in that month and were linked to a history of having visited a market where food and live animals are sold. On January 7, 2020, isolation and identification of the culprit pathogen was achieved using next-generation sequencing, while the number of affected subjects continued to rise. The publication of full-genomes of the newly identified coronavirus (initially called 2019-nCoV, now called SARS-CoV2) in public and private databases, of standardized diagnostic protocols and of the clinical-epidemiological information generated will allow addressing the Public Health Emergency of International Concern (PHEIC), declared on January 30 by the WHO. With this document, we intend to contribute to the characterization of the pneumonia epidemic, now designated coronavirus disease (Covid-19) review the strengths Mexico has in the global health concert and invite health professionals to join the preparedness and response activities in the face of this emergency.

El 31 de diciembre de 2019, las autoridades chinas de salud informaron a la comunidad internacional, a través de los mecanismos establecidos por la Organización Mundial de la Salud (OMS), de una epidemia de neumonía con etiología desconocida en Wuhan, provincia de Hubei. Los primeros casos se notificaron a inicios de ese mes y se vincularon al antecedente de visitar un mercado de comida y animales vivos. El 7 de enero de 2020 se logró el aislamiento y reconocimiento del patógeno responsable mediante secuenciación de siguiente generación, mientras el número de afectados continuaba en ascenso. La publicación de genomas completos del nuevo coronavirus identificado (inicialmente denominado 2019-nCoV, ahora designado SARS-CoV2) en bases de datos públicas y privadas, de protocolos diagnósticos estandarizados y de la información clínica epidemiológica generada permitirá atender la Emergencia de Salud Pública de Importancia Internacional (ESPII) declarada el 30 de enero por la OMS. Con este documento pretendemos aportar a la caracterización de la epidemia de neumonía, ahora llamada enfermedad por coronavirus (Covid-19), revisar las fortalezas que tiene México en el concierto de la salud global e invitar a los profesionales de la salud a incorporarse a las actividades de preparación y respuesta ante esta emergencia.
