Descripción de las intervenciones broncoscópicas en estenosis traqueales posterior a infección por COVID-19 / Description of Bronchoscopic Interventions in Post-COVID Tracheal Stenosis

Introducción: La infección por SARS-CoV-2 puede presentar síndrome de distrés res-piratorio agudo con requerimiento de ventilación mecánica prolongada y retraso en la realización de traqueostomía. Esto trae como consecuencia un incremento en casos de estenosis traqueal y la necesidad de métodos menos invasivos para su abordaje. Métodos: Estudio descriptivo de corte transversal, desde marzo 2020 hasta diciem-bre 2021 en el Hospital Universitario Nacional de Colombia, en adultos con estenosis traqueal postintubación asociado SARS-CoV-2. Se realizó análisis univariado entre los grupos con infección o no por SARS-CoV-2 como control, y reintervención, grado de estenosis, uso de inyección intramucosa con dexametasona intratraqueal o múltiples estenosis como desenlaces de importancia. Se usó test exacto de Fisher, t Student y Man-Whitney según la naturaleza de variables. Se consideró p estadísticamente significativo menor a 0.05.Resultados: Se identificaron 26 pacientes, 20 tenían COVID-19 y 6 no. Se encontraron diferencias en edad (p=0,002), epilepsia (p=0,007) y estenosis múltiple (p= 0,04). En 85% de los casos se utilizó láser blue más dilatación con balón pulmonar, en 35% inyección intramucosa con dexametasona intratraqueal y reintervención en 35%, sin diferencias significativas entre grupos. Conclusiones: Se observó un incremento tres veces mayor de pacientes con estenosis múltiple en el grupo de infección por COVID-19, así mismo se encontró que el método más utilizado en este grupo para la recanalización fue el uso de láser blue más dilatación con balón pulmonar y la innovación en el uso de inyección intramucosa.

Introduction: SARS-CoV-2 infection can lead to acute respiratory distress syndrome with a prolonged need for mechanical ventilation and delayed tracheostomy, resulting in an increase in cases of tracheal stenosis and the necessity for less invasive approaches.Methods: A descriptive cross-sectional study was conducted from March 2020 to December 2021 at the Hospital Universitario Nacional de Colombia, focusing on adults with post-intubation tracheal stenosis associated with SARS-CoV-2. Univariate analysis was performed between groups with or without SARS-CoV-2 infection as a control, considering reintervention, degree of stenosis, use of intratracheal steroids, or multiple stenoses as important outcomes. Fisher's exact test, Student's t-test, and Mann-Whit-ney test were employed based on the nature of variables. A p-value less than 0.05 was considered statistically significant.Results: A total of 26 patients were included, with 20 having COVID-19 and 6 without. Significant differences were found in age (p=0.002), epilepsy (p=0.007), and multiple stenosis (p=0.04). In 85% of cases, laser blue plus balloon pulmonary dilation was used, intratracheal dexamethasone in 35%, and reintervention in 35%, with no significant differences between groups.Conclusions: A threefold increase in subglottic stenosis was observed during the SARS-CoV-2 pandemic, with more instances of multiple stenosis and predominantly the use of laser blue plus balloon pulmonary dilation as a successful recanalization technique. There was a higher use of intratracheal dexamethasone in this group compared to oth-er pathologies causing tracheal stenosis.

Eficácia da ivermectina e atazanavir no tempo de recuperação dos sintomas de covid-19: uma coorte prospectiva / Effectiveness of ivermectin and atazanavir on time to resolution from covid-19 symptoms: a prospective cohort / Eficacia de ivermectina y atazanavir en el tiempo hasta lá resolución de los síntomas de covid-19: una cohorte prospectiva

Objetivo: avaliar a eficácia da Ivermectina e do Atazanavir em comparação com placebo no tempo de resolução dos sintomas e no tempo de duração da doença por COVID-19. Método: estudo observacional, de coorte prospectivo, longitudinal, descritivo e analítico com pacientes sintomáticos ambulatoriais, acompanhados por 06 meses em duas Unidades Básicas de Saúde para atendimento de COVID-19 em Teresina- Piauí, Brasil, no período de novembro a abril de 2021 identificados por amostragem aleatória 1:1:1. Foram realizados exames Reverse transcription polymerase chain reaction (RT-PCR) para confirmação laboratorial da suspeita de infecção pelo novo coronavírus e avaliação sociodemográfica e clínica. Resultados: dos 87 pacientes randomizados, 62,1% (n=54) eram do sexo masculino, com média de idade de 35,1 anos, possuíam companheira (53,9%), baixa renda (50,6%), eutróficos (40,7%) e sem comorbidades de saúde (78,2%). Não houve diferença entre o tempo médio para resolução dos sintomas, que foi de 21 dias (IQR, 8-30) no grupo atazanavir, 30 dias (IQR, 5-90) no grupo ivermectina em comparação com 14 dias (IQR, 9-21) no grupo controle. No dia 180, houve resolução dos sintomas em 100% no grupo placebo, 93,9% no grupo atazanavir e 95% no grupo ivermectina. A duração mediana da doença foi de 08 dias em todos os braços do estudo. Conclusão: o tratamento com atazanavir (6 dias) e ivermectina (3 dias) não reduziu o tempo de resolução dos sintomas e nem o tempo de duração da doença entre os pacientes ambulatoriais com COVID-19 leve em comparação com o grupo placebo. Os resultados não suportam o uso de ivermectina e atazanavir para tratamento de COVID-19 leve a moderado.

Objective: to evaluate the effectiveness of Ivermectin and Atazanavir compared to placebo in the time to resolution of symptoms and duration of illness due to COVID-19. Method: observational, prospective, longitudinal, descriptive and analytical cohort study with symptomatic outpatients, followed for 06 months in two Basic Health Units for COVID-19 care in Teresina-Piauí, Brazil, from November to April 2021 identified by 1:1:1 random sampling. Reverse transcription polymerase chain reaction (RT-PCR) tests were performed for laboratory confirmation of suspected infection with the new coronavirus and sociodemographic and clinical evaluation. Results: of the 87 randomized patients, 62.1% (n=54) were male, with a mean age of 35.1 years, had a partner (53.9%), low income (50.6%), eutrophic (40.7%) and without health comorbidities (78.2%). There was no difference between the median time to resolution of symptoms, which was 21 days (IQR, 8-30) in the atazanavir group, 30 days (IQR, 5- 90) in the ivermectin group compared with 14 days (IQR, 9- 21) in the control group. At day 180, there was resolution of symptoms in 100% in the placebo group, 93.9% in the atazanavir group, and 95% in the ivermectin group. The median duration of illness was 8 days in all study arms. Conclusion: Treatment with atazanavir (6 days) and ivermectin (3 days) did not reduce the time to symptom resolution or the duration of illness among outpatients with mild COVID-19 compared to the placebo group. The results do not support the use of ivermectin and atazanavir for the treatment of mild to moderate COVID-19.

Objetivo: evaluar la efectividad de Ivermectina y Atazanavir en comparación con placebo en el tiempo de resolución de los síntomas y duración de la enfermedad por COVID-19. Método: estudio de cohorte observacional, prospectivo, longitudinal, descriptivo y analítico con pacientes ambulatorios sintomáticos, seguidos durante 06 meses en dos Unidades Básicas de Salud para atención de COVID-19 en Teresina-Piauí, Brasil, de noviembre a abril de 2021 identificados por 1:1:1 muestreo aleatorio. Se realizaron pruebas de reacción en cadena de la polimerasa con transcriptasa inversa (RT-PCR) para confirmación de laboratorio de sospecha de infección por el nuevo coronavirus y evaluación sociodemográfica y clínica. Resultados: de los 87 pacientes aleatorizados, 62,1% (n=54) eran del sexo masculino, con una edad media de 35,1 años, tenían pareja (53,9%), bajos ingresos (50,6%), eutróficos (40,7%) y sin comorbilidades de salud (78,2%). No hubo diferencia entre la mediana de tiempo hasta la resolución de los síntomas, que fue de 21 días (RIC, 8-30) en el grupo de atazanavir, 30 días (RIC, 5- 90) en el grupo de ivermectina en comparación con 14 días (RIC, 9 - 21) en el grupo control. En el día 180, hubo una resolución de los síntomas del 100 % en el grupo de placebo, del 93,9 % en el grupo de atazanavir y del 95 % en el grupo de ivermectina. La mediana de duración de la enfermedad fue de 8 días en todos los brazos del estudio. Conclusión: El tratamiento con atazanavir (6 días) e ivermectina (3 días) no redujo el tiempo de resolución de los síntomas ni la duración de la enfermedad entre los pacientes ambulatorios con COVID-19 leve en comparación con el grupo placebo. Los resultados no respaldan el uso de ivermectina y atazanavir para el tratamiento de la COVID-19 de leve a moderada.

Reinfección por SARS-CoV-2 en pacientes con antecedentes de MIS-C. Presentación de dos casos / MIS-C patients who were reinfected with SARS-CoV-2. Report of 2 cases

El síndrome inflamatorio multisistémico pediátrico (MIS-C, por su sigla en inglés) es una enfermedad rara. Se desconoce si los niños que se recuperaron del MIS-C tienen riesgo de recurrencia de MIS-C cuando presentan reinfección por SARS-CoV-2. El objetivo de este estudio es describir los casos de dos niñas que se recuperaron del MIS-C y presentaron reinfección por SARS-CoV-2 sin recurrencia de MIS-C.

Multisystem inflammatory syndrome in children (MIS-C) is a rare condition. It is still unknown if children who have recovered from MIS-C are at a risk of recurrence of MIS-C when they are reinfected with SARS-CoV-2. In this study, we aimed to report 2 children who recovered from MIS-C and reinfected with SARS-CoV-2 without recurrence of MIS-C.

Structural Brain Alterations in Individuals Post-COVID-19: A Systematic Review / Alteraciones Estructurales Cerebrales en Individuos Post COVID-19: Una Revisión Sistemática

SUMMARY: Although COVID-19 is primarily considered a respiratory pathology, it has been observed to impact other bodily systems, including the nervous system. While several studies have investigated anatomical changes in brain structures, such as volume or thickness post-COVID-19, there are no comprehensive reviews of these changes using imaging techniques for a holistic understanding. The aim of this study was to systematically analyze the literature on brain changes observed through neuroimaging after COVID-19. We conducted a systematic review according to PRISMA guidelines using Web of Science, Scopus, Medline, Pubmed, Sciencedirect, and LitCOVID. We selected studies that included adult patients during or after COVID-19 development, a control group or pre-infection images, and morphometric measurements using neuroimaging. We used the MSQ scale to extract information on sample characteristics, measured anatomical structures, imaging technique, main results, and methodological quality for each study. Out of 1126 identified articles, we included 19 in the review, encompassing 1155 cases and 1284 controls. The results of these studies indicated a lower volume of the olfactory bulb and variable increases or decreases in cortical and limbic structures' volumes and thicknesses. Studies suggest that brain changes occur post-COVID-19, primarily characterized by a smaller olfactory bulb. Additionally, there may be variations in cortical and limbic volumes and thicknesses due to inflammation or neuroplasticity, but these findings are not definitive. These differences may be attributed to methodological, geographical, and temporal variations between studies. Thus, additional studies are required to provide a more comprehensive and quantitative view of the evidence.

Aunque el COVID-19 se considera principalmente una patología respiratoria, se ha observado que afecta otros sistemas corporales, incluido el sistema nervioso. Si bien varios estudios han investigado los cambios anatómicos en las estructuras cerebrales, como el volumen o el grosor posteriores a la COVID-19, no hay revisiones exhaustivas de estos cambios que utilicen técnicas de imágenes para una comprensión holística. El objetivo de este estudio fue analizar sistemáticamente la literature sobre los cambios cerebrales observados a través de neuroimagen después de COVID-19. Realizamos una revisión sistemática de acuerdo con las pautas PRISMA utilizando Web of Science, Scopus, Medline, Pubmed, Sciencedirect y LitCOVID. Seleccionamos estudios que incluyeron pacientes adultos durante o después del desarrollo de COVID-19, un grupo de control o imágenes previas a la infección y mediciones morfométricas mediante neuroimagen. Utilizamos la escala MSQ para extraer información sobre las características de la muestra, las estructuras anatómicas medidas, la técnica de imagen, los principales resultados y la calidad metodológica de cada estudio. De 1126 artículos identificados, incluimos 19 en la revisión, que abarca 1155 casos y 1284 controles. Los resultados de estos estudios indicaron un menor volumen del bulbo olfatorio y aumentos o disminuciones variables en los volúmenes y espesores de las estructuras corticales y límbicas. Los estudios sugieren que los cambios cerebrales ocurren después del COVID-19, caracterizados principalmente por un bulbo olfatorio más pequeño. Además, pueden haber variaciones en los volúmenes y grosores corticales y límbicos debido a la inflamación o la neuroplasticidad, pero estos hallazgos no son definitivos. Estas diferencias pueden atribuirse a variaciones metodológicas, geográficas y temporales entre estudios. Por lo tanto, se requieren estudios adicionales para proporcionar una visión más completa y cuantitativa de la evidencia.

Introdução: A COVID-19 pode afetar o sistema auditivo, justificando a avaliação da audição de indivíduos infectados. Objetivo: analisar a via auditiva até o tronco encefálico de indivíduos acometidos por COVID-19 comparados ao grupo controle. Método: Estudo observacional transversal analítico realizado em uma amostra não probabilística de adultos que tiveram COVID-19, que foram comparados com um grupo controle, sem queixa auditiva. A avaliação consistiu em: medidas de imitância acústica, audiometria tonal liminar (ATL), emissões otoacústicas evocadas por estímulo transiente (EOET) e potencial evocado auditivo de tronco encefálico (PEATE). Resultados: Foram avaliados 77 indivíduos, sendo, 41 participantes do grupo COVID-19 (idade média de 26,3) e 36 do grupo controle (idade média de 25,8). Os limiares auditivos estavam dentro dos padrões da normalidade para todos os indivíduos do grupo COVID-19, sendo significativamente maiores para as frequências de 1000, 2000 e 3000 Hz à direita. A amplitude das EOET foi significativamente menor na banda de frequência de 1500 à direita. Houve correlação significativa e negativa para as frequências de 1000 Hz e 3000 Hz à direita e para as frequências de 1000, 2000 e 3000 Hz à esquerda, entre EOET e ATL. Foi verificado aumento da latência absoluta da onda I, do PEATE, na orelha esquerda. Conclusão: a COVID-19 afetou locais específicos do sistema auditivo. Houve diminuição da acuidade auditiva e do funcionamento das células ciliadas externas da cóclea, bem como aumento do tempo de condução neural do som na porção distal do VII par craniano à esquerda.

Introduction: COVID-19 can affect the auditory system, justifying the evaluation of the hearing of infected individuals. Objective: to analyze the auditory pathway to the brainstem of individuals affected by COVID-19 compared to the control group. Method: Analytical cross-sectional observational study carried out in a non-probabilistic sample of adults who had COVID-19, who were compared with a control group, without hearing complaints. The evaluation consisted of: acoustic immittance measurements, pure tone audiometry (PTA), transient stimulus-evoked otoacoustic emissions (TEOAE) and brainstem auditory evoked potential (BAEP). Results: 77 individuals were evaluated, 41 participants in the COVID-19 group (average age of 26.3) and 36 in the control group (average age of 25.8). Hearing thresholds were within normal limits for all individuals in the COVID-19 group, being significantly higher for the frequencies of 1000, 2000 and 3000 Hz on the right. TEOAE amplitude was significantly lower in the 1500 frequency band on the right. There was a significant and negative correlation for the frequencies of 1000 Hz and 3000 Hz on the right and for the frequencies of 1000, 2000 and 3000 Hz on the left, between TEOAE and PTA. An increase in the absolute latency of wave I, of the BAEP, was observed in the left ear. Conclusion: COVID-19 affected specific locations in the auditory system. There was a decrease in auditory acuity and the functioning of the outer hair cells of the cochlea, as well as an increase in the neural conduction time of sound in the distal portion of the VII cranial nerve on the left.

Morbilidad de las fracturas vertebrales osteoporóticas durante el aislamiento social en la pandemia COVID-19 / Osteoporotic vertebral fractures morbidity during social isolation on COVID-19 pandemic

Introducción: la pandemia por COVID-19 afectó negativamente los sistemas de salud. Las fracturas vertebrales osteoporóticas y el aislamiento social se relacionan con mayor morbimortalidad. Objetivos: caracterizar la morbilidad de las fracturas vertebrales osteoporóticas y evaluar una posible relación entre morbilidad y nivel de aislamiento social se-cundario al estado de pandemia. Material y métodos: estudio observacional, analítico y transversal. Resultados: se incluyeron en el estudio 45 adultos. La fractura fue mayorita-riamente lumbar con una evolución superior de 3 meses. El 35% presentaba seguimiento, el 48% había recibido tratamiento para osteoporosis y el 48% presentaba fracturas previas documentadas. El 46% refirió falta de accesibilidad al sistema. Se evaluó el aisla-miento social con la escala sociofamiliar de Gijón, que evidenció una situación buena en el 75% y un deterioro social intermedio/severo en el 24%. El Índice de Oswestry mostró una discapacidad mínima/moderada en el 66% y severa o mayor en el 33%. Se evaluó el dolor por la Escala análoga visual (VAS) y se obtuvo un VAS mayor de 5 en el 57%. Al comparar el grupo de situación sociofamiliar buena con el de deterioro social intermedio/severo se observó una diferencia en multipli-cidad de fracturas (p 0,030), hipovitaminosis D (p 0,045) y falta de accesibilidad (p 0,029). En discapacidad y dolor no hubo diferencias. Conclusión: el grupo con mayor aislamiento presentó una enfermedad más severa en términos de multiplicidad de fracturas e hipovitaminosis D; esto podría indicar una asociación entre aislamiento social secundario al estado de pandemia y morbilidad por las fracturas vertebrales. (AU)

Introduction: the COVID-19 pandemic had a negative impact on healthcare systems. Osteoporotic vertebral fractures and social isolation have a significant morbidity in our setting. Objectives: to characterize the morbidity of osteoporotic vertebral fractures and evaluate a potential relationship between morbidity and the level of social isolation secondary to the pandemic. Material and methods: observational, analytical and cross-sectional study. Results: forty-five adults were included. Fractures were mostly lumbar with a history of over 3 months. Thirty-five percent (35%) had been followed-up, 48% had been treated for osteoporosis and 48% had previous documented fractures. Forty-six percent (46%) reported lack of accessibility to healthcare. Social isolation was measured using Gijón ́s social-familial evaluation scale, which showed a good situation in 75% of cases and an intermediate/severe social deterioration in 24%. According to the Oswestry index, disability was minimal/moderate in 66% of cases and severe or worse in 33%. Pain was assessed using the Visual Analogue Scale (VAS), with a score greater than 5 recorded in 57% of patients. When comparing the group with a good social-familial situation vs. the group with intermediate/severe social deterioration, differences were found in multiplicity of fractures (p 0.030), hypovitaminosis D (p 0.045) and lack of accessibility (p 0.029). No differences were found in disability and pain. Conclusion: the group with higher levels of isolation exhibited more severe disease in terms of multiplicity of fractures and hypovitaminosis D, which might suggest an association between social isolation secondary to the pandemic and morbidity due to vertebral fractures.

Manifestações orais e Covid-19: Revisão Sistemática da literatura / Oral Manifestations and Covid-19: Systematic literature review

A doença COVID-19, que se tornou uma pandemia em pouco espaço de tempo, apresenta uma ameaça grave para a saúde global. As condições bucais de pacientes com COVID-19 foram analisadas em vários estudos. Diante disso, observou-se que diversas manifestações bucais foram encontradas nesses pacientes. O objetivo deste trabalho foi realizar uma revisão de literatura sistemática sobre as manifestações bucais que podem estar associadas à doença COVID-19. A pesquisa foi realizada por meio de uma revisão sistemática nas bases de dados Bireme, PubMed e SciELO, no período de 30 de abril de 2021 a 11 de maio de 2023. A busca utilizou os descritores "COVID-19", "coronavirus" e "oral manifestations". Foram utilizados como critério de inclusão a presença do artigo completo disponível na íntegra e publicado nos anos de 2020 a 2023 e excluídos aqueles que não relatavam alguma manifestação da COVID-19 ou que não abordavam formas de tratamento. Foram incluídos 19 artigos. As informações foram compiladas de forma a compreender a importância de se investigar as manifestações orais em decorrência dessa doença, devido a sua importância internacional dadas às suas circunstâncias devastadoras. Concluiu-se que é notável a importância da anamnese e o exame intraoral para diagnosticar as manifestações orais nos pacientes sob suspeita ou confirmados com a COVID-19, e o diagnóstico precoce das alterações é fundamental para assegurar um suporte adequado ao paciente acometido. Mais estudos são necessários para comprovar a associação direta entre a COVID-19 e as manifestações orais relatadas.

COVID-19, which has become a pandemic in a short time, poses a serious threat to global health. The oral conditions of patients with COVID-19 have been analyzed in several studies. Therefore, it was observed that several manifestations were found in these patients. The objective of the work is to carry out a systematic literature review on the oral manifestations that may be associated with the disease COVID-19. The research was carried out through a systematic review in the databases Bireme, PubMed and SciELO, from April 30, 2021 o May 11, 2023. The search using the descriptors "COVID-19", "coronavirus" and "Oral manifestations". Inclusion criteria were the presence of the full article available in full and published in 2020 and 2023. Articles that did not report any manifestation of COVID-19 or those that did not address forms of treatment were excluded. 19 articles were included. The information was compiled in order to understand the importance of investigating oral manifestations as a result of this disease, due to its international importance given to its devastating entities. It was concluded that the importance of anamnesis and intraoral examination for the diagnosis of oral manifestations in patients suspected or confirmed with COVID-19 is remarkable, and the early diagnosis of alterations is essential to ensure adequate support for the affected patient. Further studies are needed to prove the direct association between COVID-19 and the reported oral manifestations.

Bruxismo como consequência do estresse pandêmico: revisão integrativa / Bruxism as a consequence of pandemic stress: integrative review

O período pandêmico com todas as suas implicações possibilitou um aumento dos níveis de estresse em parte da população, que teve como consequência a obtenção ou o agravamento do bruxismo. Objetivo: O objetivo deste artigo foi realizar uma revisão integrativa sobre como o estresse causado pela pandemia de COVID-19 influenciou no desenvolvimento do bruxismo, considerando o perfil dos indivíduos acometidos. Realizou-se uma revisão integrativa da literatura a partir da seleção de artigos publicados nas bases de dados BVS, PubMed e EBSCOhost. Para isto, a seguinte questão de pesquisa foi formulada: "Existe relação entre o bruxismo e a pandemia de COVID-19?". A busca objetivou encontrar artigos publicados em português, espanhol e inglês, durante os anos de 2019 a 2023, utilizando os descritores "bruxismo", "COVID-19" e "estresse psicológico" e as suas respectivas versões em inglês, juntamente com a estratégia de busca AND. Revisão de literatura: Vinte estudos foram incluídos, ficando evidente uma prevalência do bruxismo como consequência do estresse pandêmico em pessoas jovens, do sexo feminino, além de estudantes/profissionais da área da saúde. Considerações finais: Acredita-se que a pandemia de COVID-19 vivenciada entre os anos de 2019 e 2023 tenha causado e/ou exacerbado estresse, sendo este um importante fator causador do bruxismo.(AU)

The pandemic period with all its implications allowed an increase in stress levels in part of the population, which resulted in the obstruction or worsening of bruxism.

Estrés, burnout y emociones en personal de salud ante la emergencia por COVID-19 / Stress, burnout and emotions in health workers´ emergency conditions due to the COVID-19

La situación epidemiológica originada por la COVID-19 provocó nuevas demandas a las ya existentes en el personal de salud. Objetivos: Describir las dimensiones del síndrome de burnout: agotamiento emocional, despersonalización y falta de realización profesional en el personal del área de salud, determinar los niveles de estrés, explorar el ambiente emocional en sus dimensiones de afectividad positiva y negativa y delimitar la relación entre estas variables. Estudio cuantitativo con un diseño descriptivo de corte transversal, en un Policlínico durante el mes de diciembre del 2021. En personal médico (n=23) y de enfermería (n=16), se aplica el Inventario de burnout de Maslach, la Escala sintomática de estrés y la Escala de afectividad positiva y negativa. Resultados: Se obtiene agotamiento emocional alto en el 30,8%, medio en 33,3%; despersonalización, en un sujeto fue alto, y en 6 medio; la eficacia profesional en 9 sujetos fue medio y en 1 bajo; el nivel de estrés fue patológico en 41%, la afectividad positiva es alta en 53,8%, la negativa en el 5,1%. No existen diferencias respecto al sexo, ocupación y haber padecido o no COVID-19, se constata relación inversa entre la despersonalización y la edad. Conclusiones: La relación directa entre el estrés, agotamiento emocional y afectividad negativa son expresión de un desgaste producto de las respuestas fisiológicas y emocionales a situaciones mantenidas de movilización de recursos en el entorno laboral, lo cual se manifiesta en el grupo estudiado. Se recomiendan acciones dirigidas a intervenir de modo participativo y prevenir el ambiente emocional negativo(AU)

The epidemiological situation originated by COVID-19 caused new demands to those already existing in health personnel. Objectives: Describe the dimensions of the burnout syndrome, determine the levels of stress explore the emotional environment in its positive and negative affectivity dimensions and define the relationship between these variables. Quantitative study with crosssectional design, in a polyclinic during the month of December 2021. In medical (n=23) and nursing (n=16) staff the Scale of Positive and Negative Affect -PANAS- the Symptomatic Scales of Stress and the Maslach Burnout Inventory were applied. Measures of central tendency, absolutes and relative frequencies, measures of association and correlation coefficients with a reliability of 95% were used. Results: High emotional exhaustion is obtained in 30.8%, medium in 33.3%, depersonalization in one subject was high and in 6 medium, professional efficacy in 9 subjects was medium and in 1 low; the level of pathological stress in 41%, the positive affectivity is high in 53,8%, the negative in the 5.1%. There are no differences regarding sex, occupation and having suffered or not COVID-19. An inverse relationship between depersonalization and age is verified. Conclusions: The direct relationship between stress, emotional exhaustion and negative affectivity are expressions of a wear due to the physiological and emotional response to chronic situations of mobilization of resource at work. Actions aimed at intervening in a participatory way and preventing the negative emotional environment is recommended(AU)

Inmunización con vacunas ARN mensajero contra la COVID-19 en pacientes adolescentes con antecedente de síndrome inflamatorio multisistémico: serie de casos / Immunization with messenger RNA vaccines against COVID-19 in adolescents with a history of multisystem inflammatory

Los niños cursan mayormente la infección por el virus SARS-CoV-2 en forma leve. Sin embargo, de forma muy infrecuente algunos pueden desarrollar una patología con marcada gravedad denominada síndrome inflamatorio multisistémico en niños relacionado temporalmente con COVID-19 (SIM-C). Dado su reciente surgimiento, aún hay aspectos de su fisiopatología que se desconocen. La posibilidad de recidiva en caso de reinfección o ante la vacunación contra SARS-CoV-2 son nuevos interrogantes a los que nos enfrentamos. Reportamos una serie de casos de 4 pacientes adolescentes que cursaron SIM-C y meses después han sido vacunados contra SARS-CoV-2 con plataformas ARN mensajero (ARNm) sin presentar recurrencia de la enfermedad ni efectos adversos cardiológicos

In most cases, children with SARS-CoV-2 have a mild infection. However, very rarely, some children may develop a severe disease called multisystem inflammatory syndrome in children temporally associated with COVID-19 (MIS-C). Given its recent emergence, some aspects of its pathophysiology are still unknown. The possibility of recurrence in case of reinfection or SARS-CoV-2 vaccination are new questions we are facing. Here we report a case series of 4 adolescent patients who developed MIS-C and, months later, received the SARS-CoV-2 vaccine with messenger RNA (mRNA) platforms without disease recurrence or cardiac adverse events.

Brazilian Black Women are at Higher Risk for COVID-19 Complications: An Analysis of REBRACO, a National Cohort / Mulheres negras brasileiras correm maior risco de complicações da COVID-19: uma análise do REBRACO, uma coorte nacional

Abstract Objective To evaluate the impact of the race (Black versus non-Black) on maternal and perinatal outcomes of pregnant women with COVID-19 in Brazil. Methods This is a subanalysis of REBRACO, a Brazilian multicenter cohort study designed to evaluate the impact of COVID-19 on pregnant women. From February2020 until February 2021, 15 maternity hospitals in Brazil collected data on women with respiratory symptoms. We selected all women with a positive test for COVID-19; then, we divided them into two groups: Black and non-Black women. Finally, we compared, between groups, sociodemographic, maternal, and perinatal outcomes. We obtained the frequency of events in each group and compared them using X2 test; p-values < 0.05 were considered significant. We also estimated the odds ratio (OR) and confidence intervals (CI). Results 729 symptomatic women were included in the study; of those, 285 were positive for COVID-19, 120 (42.1%) were Black, and 165 (57.9%) were non-Black. Black women had worse education (p = 0.037). The timing of access to the health system was similar between both groups, with 26.3% being included with seven or more days of symptoms. Severe acute respiratory syndrome (OR 2.22 CI 1.17-4.21), intensive care unit admission (OR 2.00 CI 1.07-3.74), and desaturation at admission (OR 3.72 CI 1.41-9.84) were more likely to occur among Black women. Maternal death was higher among Black women (7.8% vs. 2.6%, p = 0.048). Perinatal outcomes were similar between both groups. Conclusion Brazilian Black women were more likely to die due to the consequences of COVID-19.

Resumo Objetivo Avaliar o impacto da raça (negra versus não negra) nos desfechos maternos e perinatais de gestantes com COVID-19 no Brasil. Métodos Esta é uma subanálise da REBRACO, um estudo de coorte multicêntrico brasileiro desenhado para avaliar o impacto da COVID-19 em mulheres grávidas. De fevereiro de 2020 a fevereiro de 2021, 15 maternidades do Brasil coletaram dados de mulheres com sintomas respiratórios. Selecionamos todas as mulheres com teste positivo para COVID-19; em seguida, as dividimos em dois grupos: mulheres negras e não negras. Finalmente, comparamos, entre os grupos, os resultados sociodemográficos, maternos e perinatais. Obtivemos a frequência dos eventos em cada grupo e comparamos usando o teste X2; Valores de p <0,05 foram considerados significativos. Também estimamos o odds ratio (OR) e os intervalos de confiança (IC). Resultados 729 mulheres sintomáticas foram incluídas no estudo; desses, 285 foram positivos para COVID-19, 120 (42,1%) eram negros e 165 (57,9%) não eram negros. As mulheres negras apresentaram pior escolaridade (p = 0,037). O tempo de acesso ao sistema de saúde foi semelhante entre os dois grupos, com 26,3% incluídos com sete ou mais dias de sintomas. Síndrome respiratória aguda grave (OR 2,22 CI 1,17-4,21), admissão em unidade de terapia intensiva (OR 2,00 CI 1,07-3,74) e dessaturação na admissão (OR 3,72 CI 1,41-9,84) foram mais prováveis de ocorrer entre mulheres negras. A mortalidade materna foi maior entre as negras (7,8% vs. 2,6%, p = 0,048). Os resultados perinatais foram semelhantes entre os dois grupos. Conclusão Mulheres negras brasileiras tiveram maior probabilidade de morrer devido às consequências da COVID-19.

Ultrasound-guided central venous access for patients in the Intensive Care Unit in prone position: report of three cases

Abstract The prone position is extensively used to improve oxygenation in patients with severe acute respiratory distress syndrome caused by SARS-CoV-2 pneumonia. Occasionally, these patients exhibit cardiac and respiratory functions so severely compromised they cannot tolerate lying in the supine position, not even for the time required to insert a central venous catheter. The authors describe three cases of successful ultrasound-guided internal jugular vein cannulation in prone position. The alternative approach here described enables greater safety and well-being for the patient, reduces the number of episodes of decompensation, and risk of tracheal extubation and loss of in-situ vascular lines.

Oral lesions after infection by SARS CoV 2: two case reports / Lesiones bucales posteriores a infección por SARS CoV 2 presentación de dos casos

Introduction: The SARS CoV 2 infection has resulted in several health, economic, and social crises in all areas. The disease shows a substantial biological diversity in humans causing a series of sequels in the trans- or post-infection period in the entire organism. Case Report: The manifestations that occur in the oral cavity and pharynx have not been evaluated. In this study, two clinical cases are reported. The first patient, a 67-year-old male, presents erosive lesions on the dorsal surface of his tongue after SARS CoV 2 infection. Results: Therapy consisting of reinforcing oral cleaning, use of antifungal solutions, mouthwashes containing superoxidation solution and B complex was given to the patient. The reported lesions improved satisfactorily. The second case, a 47-year-old male patient, presented vesiculobullous lesions on the lingual and labial mucosa accompanied by severe painful symptoms after SARS CoV 2 infection. An incisional biopsy was performed. The histopathological result was compatible with pemphigus vulgaris, and the treatment protocol was started with 0.1% topical mometasone and 2g miconazole gel, observing adequate involution of the lesions after 20 days. Conclusions: The aim of this study is to report on the lesions affecting the oral cavity and pharynx in post-COVID patients with the aim of carrying out a thorough intraoral examination, establishing a clinical or histopathological diagnosis to implement a specific treatment plan in each case to improve the health and quality of life of the patients. Keywords: SARS-CoV-2; Oral manifestations; Oral ulcer; Pemphigus; Mouth; Mucous membrane.

Introducción: La infección por virus de SARS CoV 2 ha dejado a su paso una estela de crisis en materia de salud, económica, social y en todos los ámbitos a la fecha seguimos realizando la observación del comportamiento de la enfermedad en los seres humanos con una diversidad biológica importante y que ha traído como consecuencia una serie de secuelas que se presentan en el periodo trans o posterior a la infección en toda la economía corporal. Reporte de Caso: Se ha evaluado poco las manifestaciones que se presentan en la cavidad bucal y faringe; se presentan dos casos clínicos el primero paciente masculino de 67 años de edad posterior a la infección por SARS CoV 2 presenta diluciones de continuidad en bordes laterales de la lengua se indica terapia y refuerza limpieza bucal, antimicótico, colutorios con solución de superoxidación y complejo B, las úlceras involucionan de manera satisfactoria. Resultados: El segundo caso masculino de 47 años posterior a la infección por SARS CoV 2 debuta con lesiones vesículo-ampollosas en mucosa lingual, labial con sintomatología dolorosa severa, se realiza biopsia incisional donde el resultado histopatológico es compatible con pénfigo vulgar, se inicia protocolo de tratamiento con mometasona tópica al 0.1% y miconazol gel 2g observándose una adecuada involución de las lesiones a los 20 días. Conclusiones: El objetivo de este trabajo es poner en contexto de la comunidad médica y científica las lesiones concernientes a la cavidad bucal y faringe que están presentando los pacientes postcovid con el objetivo de realizar una exhaustiva exploración intraoral, establecer un diagnóstico clínico o histopatológico y con base en esto instaurar un plan de tratamiento específico en cada caso en particular con el fin fundamental de mejorar la salud y calidad de vida del paciente.

Brote de histoplasmosis en el contexto de la pandemia por COVID-19 / Histoplasmosis outbreak in the context of the COVID-19 pandemic

La histoplasmosis es una micosis profunda de distribución mundial causada por el Histoplasma capsulatum var. capsulatum. Se caracteriza por una variabilidad clínica que depende principalmente de la carga fúngica, del estado inmunológico del paciente y de la virulencia del germen. Se describe un brote de histoplasmosis pulmonar aguda en militares, producido en el contexto epidemiológico de la COVID-19. El episodio tuvo lugar a partir de actividad laboral en cuevas donde participaron cuatro militares, tres de los cuales desarrollaron síntomas y fueron admitidos en el Hospital Dr. Gustavo Aldereguía Lima de Cienfuegos en enero de 2022. La información fue obtenida a través de la entrevista médica y la historia clínica. Se evidenció que en el contexto epidemiológico de la pandemia por COVID-19 no se debe subestimar el diagnóstico de otras enfermedades respiratorias, incluidas las micosis endémicas(AU)

Histoplasmosis is a deep mycotic infection of worldwide distribution caused by Histoplasma capsulatum var. capsulatum. It is characterized by clinical variability that depends mainly on the fungal load, the patient's immune status and the virulence of the germ. We describe an outbreak of acute pulmonary histoplasmosis among military officers, which occurred in the epidemiological context of COVID-19. The episode occurred during work activities in caves in which four soldiers participated, three of whom developed symptoms and were admitted to the "Dr. Gustavo Aldereguía Lima" Hospital in Cienfuegos in January 2022. The information was obtained through medical interviews and clinical records. It was evidenced that in the epidemiological context of the COVID-19 pandemic, the diagnosis of other respiratory diseases, including endemic mycoses, should not be underestimated(AU)

Resumen Objetivo. Esta investigación tiene como objetivo describir la población atendida y los beneficios del programa "Lineamiento de atención integral por Cuidados Paliativos en el Área de Salud de Palmares, para pacientes con SARS-CoV-2 severo" con ventilación mecánica asistida, hospitalizados en unidades de cuidados intensivos de la Caja Costarricense del Seguro Social durante la pandemia en Costa Rica, del 10 de junio al 31 de octubre del 2021. Métodos. Estudio descriptivo mixto de la población y los beneficios del programa por medio de indicadores cuantitativos obtenidos del informe de aplicación y cualitativos a través de la realización de una encuesta de satisfacción a usuarios en el período de estudio. Resultados. El programa atendió a 13 pacientes, brindó apoyo en manejo del duelo a los familiares de cinco pacientes que ya habían fallecido y a los cuidadores de ocho pacientes hospitalizados, también ofreció 70 consultas médicas en un período promedio de 62 días. La edad promedio de los pacientes fue de 55 años; doce pacientes presentaban algún factor de riesgo, siendo la obesidad y la falta de esquema de vacunación completo (dos dosis) los más frecuentes. Durante la implementación del programa fallecieron cinco pacientes más, obteniendo una tasa de mortalidad del 78%. A los pacientes que sobrevivieron se les atendió en promedio por 135 días. Con el apoyo del equipo, los pacientes lograron la recuperación clínica de las complicaciones respiratorias y funcionales. Lograron independencia total de actividades básicas de la vida diaria y reinserción social en menos de tres meses después del alta hospitalaria. En general, se documentó una percepción positiva del programa en el 100% de los usuarios, con cambios en el nivel de sufrimiento manifestado por las familias y el apoyo en el manejo del duelo. Conclusión. Con la optimización de uso de los recursos ya existentes en la Caja Costarricense del Seguro Social y la participación social, este programa abordó aspectos no atendidos previamente para los pacientes que sufrieron COVID 19 severo, como el manejo del sufrimiento y/o duelo durante la hospitalización y al egreso. Además, el programa colaboró en la recuperación clínica y funcional de los usuarios sobrevivientes y documentó múltiples beneficios percibidos por el paciente, sus familias, la institución y la sociedad, como el abordaje del sufrimiento, la adecuada atención al duelo, la organización de los recursos asistenciales y la pronta recuperación física, emocional y social del paciente sobreviviente.

Abstract Aim. This research aims to describe the population served and the benefits of the program "Guidelines for integral care for patients with severe SARS-CoV-2 by Palliative Care at the Area de Salud de Palmares " to patients with assisted mechanical ventilation, hospitalized in intensive care units of the Caja Costarricense del Seguro Social during the pandemic in Costa Rica, from June 10 to October 31, 2021. Methods. This study is a mixed descriptive investigation that analyzes quantitative indicators from the report on the program's application and qualitative indicators from a satisfaction survey for the users in the study period. Results. The program treated 13 patients, provided grief management support to the relatives of five patients who had already died and to the caregivers of eight hospitalized patients, and offered 70 medical consultations in an average period of 62 days. The average age of the patients was 55 years; twelve patients had some risk factors, and obesity and lack of a complete vaccination schedule (two doses) were the most frequent. During the program implementation, five more patients died, obtaining a mortality rate of 78%. The average treatment day for surviving patients was 135 days. Through the team's support, patients accomplished clinical recovery from respiratory and functional complications. They got independent basics activities of daily living and social reintegration in less tan three months after discharge. A positive perception of the program was documented in 100% of the program's users, with changes in the level of suffering manifested by the families and the support in grief management. Conclusion. With the optimization of the use of existing resources in the the Caja Costarricense del Seguro Social and the social participation, this program addressed aspects not previously attended to patients who suffered severe COVID 19, such as the management of suffering and/or grief during hospitalization and upon discharge. In addition, the program helped in the clinical and functional recovery of the surviving users, and documented multiple benefits perceived by the patient, their families, the institution, and society, such as the approach to suffering, adequate bereavement care, organization of care resources, and early physical, emotional and social recovery of the survivor patient.

Múltiples reacciones adversas graves a fármacos en un paciente luego de la infección por COVID-19: informe de un caso / Drug-induced severe cutaneous adverse reactions in a patient after COVID-19 infection: case report

Durante la pandemia por COVID-19 se observaron diversas reacciones adversas a fármacos. Esto pudo haber estado relacionado con una mayor susceptibilidad inmunológica de los pacientes con SARS-CoV-2 a presentar este tipo de cuadros, así como también con la exposición a múltiples medicamentos utilizados en su tratamiento. Comunicamos el caso de un paciente con una infección respiratoria grave por COVID-19, que presentó 2 reacciones adversas graves a fármacos en un período corto de tiempo. (AU)

During the COVID-19 pandemic, various adverse drug reactions were observed. This could have been related to a greater immunological susceptibility of patients with SARS-CoV-2 to present this type of symptoms, as well as exposure to multiple drugs used in their treatment. We report the case of a patient with a severe respiratory infection due to COVID-19, who presented 2 serious adverse drug reactions associated with paracetamol in a short period of time. (AU)
