Distonía laríngea post COVID-19: reporte de dos casos y posible explicación fisiopatogénica

La distonía laríngea (DL), también conocida como disfonía espasmódica, es un desorden focal tarea-específico del movimiento, que afecta primariamente la producción de la voz. Los movimientos distónicos de las cuerdas vocales producen fenómenos diferentes, especialmente quiebres o interrupciones vocales y tensión en el tipo de distonía laríngea aductora (DLAD), e interrupciones y soplo o segmentos áfonos en el tipo abductor (DLAB). Más del 80% de pacientes sufren de DLAD o DEAD (disfonía espasmódica aductora). Dos pacientes de sexo femenino desarrollaron DL un mes después de haber contraído una infección del tracto respiratorio superior causada por COVID-19. Ambas presentaron distonía laríngea de tipo aductor. En el análisis acústico de la vocal /a/ sostenida se han observado quiebres o interrupciones, cambios frecuenciales y aperiodicidad. El rango de habla fue estudiado en ambas pacientes mediante el fonetograma, dando un resultado alterado. Posiblemente la inflamación de los nervios periféricos de la laringe, causada por COVID-19, produjo una alteración sensitiva con una respuesta mal adaptativa en estas pacientes con una base genética quizás predisponente. O la activación inmunológica, o la invasión del germen a través de la vía retrógrada alteraron las redes neuronales involucradas en la génesis de la DL.

Laryngeal dystonia (LD), also known as spasmodic dysphonia, is a task-specific focal movement disorder, primarily affecting voice production. The dystonic movements of the vocal folds result in a varied phenomenology, typically hard vocal breaks and strain in the adductor-type laryngeal dystonia (ADLD), and breathy breaks or aphonia in the abductor-type laryngeal dystonia (ABLD). More than 80% of patients have suffered from ADLD. Two female patients developed LD a month after presenting an upper respiratory tract infection by COVID-19. They had the adductor-type laryngeal dystonia. Through the acoustic study of the vowel /a/ breaks, frequency changes and aperiodicity were observed. Speech was studied using the phonetogram, and the range of speech is altered in both patients. The inflammation of the peripheral nerves of the larynx by COVID-19 produced a sensory alteration, with a maladaptive response in these patients, who perhaps had predisposing genetic basis, or the immunological activation or the invasion of the germ by retrograde pathway altered the neuronal networks involved in the genesis of LD.

Etapa subaguda de pos-COVID-19 grave o crítico. Rehabilitación musculoesquelética, respiratoria y uso de corticoides. Experiencia de la Unidad de Rehabilitación del Hospital del Banco de Seguros del Estado (URHBSE)

está disponible en el texto completo

Introduction: In patients with severe or critical COVID-19, the use of prednisone and musculoskeletal and respiratory rehabilitation has been described. The role of these interventions and the optimal time for their initiation are not clearly established. This study presents the results of the Rehabilitation Unit of the Banco de Seguro del Estado Hospital, which implemented a comprehensive rehabilitation program and the use of corticosteroids in the subacute stage of patients with severe or critical post-COVID-19, with a systematic approach, working interdisciplinary and centered on the person being treated. Findings at admission, oxygen requirement, Barthel scale, tomographic patterns, use of corticosteroids, their response, and complications are reported. The results of this approach on clinical, respiratory, and functional variables are described. Method: Descriptive, retrospective study of post-COVID-19 patients who completed rehabilitation at the Rehabilitation Unit of the Banco de Seguros del Estado Hospital (URHBSE) in the period April-August 2021. Data obtained from review of medical records, statistical analysis with PRISM (v8.2.1). Results: Eighty-four patients completed the rehabilitation program. Upon admission to the URHBSE, 55% had total or severe dependence on the Barthel scale. Forty-eight percent were unable to walk. Eighty-nine-point two percent required oxygen, with a mean saturation of 90.3 ± 4.8. Twenty-five percent of patients were admitted requiring a reservoir mask. All patients who entered the program were in the subacute phase of the disease (4 to 12 weeks) and received a comprehensive and individualized rehabilitation plan. The objective was to achieve a functional situation similar to what they had before COVID-19. The length of stay at the URHBSE was 23.5 ± 13.8 days. A total of 76 patients (90.5%) underwent high-resolution chest tomography (HRCT), which was pathological in 96.1% of cases. The predominant findings were ground-glass opacity in 49.3% of cases, consolidation in 8.23%, and a fibrosis-like pattern in 30.13%. "Non-typical" post-COVID damage tomographic alterations were detected (pleural effusion, cavitary nodules, apical cavities, etc.) in 11.8% of the tomographies. In 2 patients (2.6%), pulmonary aspergillosis was found, and in 6.6%, pulmonary thromboembolism. Forty-four patients (52.3%) received prednisone. In 63.4% of cases, oxygen supplementation was discontinued within the first 15 days from the start of prednisone. We found an association between the ground-glass opacity tomographic pattern and early discontinuation of oxygen supplementation from the start of prednisone (p = 0.047). Despite the high degree of colonization, we did not observe infections by colonizing microorganisms, even in those who used prednisone. Comparing admission and discharge, statistically significant differences were found in the following parameters: degree of dyspnea, oxygen requirement (only one patient was discharged with oxygen), saturation, degree of instrumentation (tracheostomy, nasogastric tube, etc.), and the Barthel dependency scale. Regarding respiratory variables, we only have data on the presence of dyspnea in the first 35 patients. Of these, 83% had dyspnea at admission, while only 17% had it at discharge (p < 0.0001). There were also significant differences in the oxygen requirement between admission and discharge (p < 0.0001) and in the degree of dependency measured on the Barthel scale. Fifty-five percent of patients had total or severe dependence at admission, compared to only 3.4% at discharge. Conclusions: The interventions carried out in the subacute stage of the disease were associated with significant improvements in clinical variables of interest. More studies are needed to define the role and the exact timing of the initiation of corticosteroids and rehabilitation in this group of patients.

Introdução: O uso de prednisona e reabilitação musculoesquelética e respiratória foi descrito no tratamento de pacientes com COVID-19 grave ou crítico. O papel destas intervenções e o momento ideal para o seu início não estão claramente estabelecidos. Este trabalho mostra os resultados da Unidade de Reabilitação Hospitalar do Banco de Seguro del Estado que implementou um programa abrangente de reabilitação e uso de corticosteroides na fase subaguda de pacientes graves ou críticos pós-COVID-19, com uma abordagem sistematizada, trabalhando de forma interdisciplinar e centrada no paciente. São relatados os achados na admissão, a necessidade de oxigênio, a escala de Barthel, os padrões tomográficos, o uso de corticosteroides, a resposta ao tratamento e as complicações. Os resultados desta abordagem sobre variáveis clínicas, respiratórias e funcionais são descritos. Material e métodos: Estudo descritivo e retrospectivo de pacientes pós-COVID-19 que completaram reabilitação na Unidade de Reabilitação do Hospital Banco de Seguros del Estado (URHBSE) no período de abril a agosto de 2021. Os dados foram obtidos dos prontuários de pacientes com posterior análise estatísticas usando PRISM (v8.2.1). Resultados: 84 pacientes completaram o programa de reabilitação. No momento da admissão na URHBSE, 55% apresentavam dependência total ou grave da escala de Barthel. 48% não conseguiam se mover. 89,2% necessitaram oxigênio com saturação média de 90,3 ± 4,8. 25% dos pacientes foram internados necessitando máscara com reservatório. Todos os pacientes que ingressaram no programa estavam na fase subaguda da doença (4 a 12 semanas) e receberam um plano de reabilitação abrangente e individualizado. O objetivo era alcançar uma situação funcional semelhante à que apresentavam antes da COVID-19. O tempo de permanência na URHBSE foi de 23,5±13,8 dias. A tomografia de tórax de alta resolução (TCAR) foi realizada em 76 pacientes (90,5%); os resultados foram patológicos em 96,1%. O vidro fosco predominou em 49,3% deles, a consolidação em 8,23% e o padrão fibroso em 30,13%. Alterações tomográficas "atípicas" de danos pós-COVID (derrame pleural, nódulos cavitados, cavidades apicais, etc.) foram detectadas em 11,8% dos exames tomográficos. Aspergilose pulmonar foi encontrada em 2,6% dos pacientes e tromboembolismo pulmonar em 6,6%. 44 pacientes (52,3%) receberam prednisona. Em 63,4% a oferta de oxigênio foi suspensa nos primeiros 15 dias após o início da mesma. Encontramos associação entre o padrão tomográfico em vidro fosco e a suspensão precoce da oferta de oxigênio desde o início da administração da prednisona (p = 0,047). Apesar do alto grau de colonização, mesmo naqueles que usaram prednisona, não observamos infecções. Em relação às variáveis respiratórias, só temos dados sobre a presença de dispneia nos primeiros 35 pacientes; destes, 83% apresentavam dispneia na admissão, enquanto apenas 17% a apresentavam na alta (p< 0,0001). Observou-se também diferenças significativas na necessidade de O2 entre a admissão e a alta (p< 0,0001) e no grau de dependência medido pela escala de Barthel, com 55% dos pacientes apresentando dependência total ou grave na admissão e apenas 3,4% na alta. Conclusões: As intervenções realizadas na fase subaguda da doença foram associadas a melhorias significativas nas variáveis de interesse clínico. São necessários mais estudos para definir o papel e o momento exato do início dos corticosteroides e da reabilitação neste grupo de pacientes.

Post-COVID-19 unilateral upper lip numbness: A case report

@#This is a case of a 63-year-old female with post-COVID-19 unilateral upper lip pain and numbness. Neurologic examination did not reveal any deficits other than deficits on pinprick in the maxillary division (V2) of the left trigeminal nerve. Brain neuroimaging showed signs of acute inflammation of the left maxillary sinus. Neuropraxia of the infraorbital nerve, a branch of the trigeminal nerve, was the diagnosis considered. Reports on trigeminal neurosensory changes following acute sinusitis are few, and isolated trigeminal neuropathy is rare except in cases of dental disorders. Up to this writing, there have been no reports on post-COVID-19 unilateral upper lip numbness and pain. This study will also serve as a concise review on the correlative neuroanatomy of the trigeminal nerve.

Síndrome post COVID-19. Gravedad y evolución en 4673 trabajadores sanitarios / Post COVID-19 syndrome. Severity and evolution in 4673 health care workers

Resumen Introducción : La evolución del síndrome post COVID ha sido variable y carecemos de información sobre su impacto en los profesionales de la salud. Métodos : Realizamos una encuesta a través de una red social en profesionales de la salud sobre casos de síndrome post COVID-19 confirmados con PCR. En un cuestionario web, preguntamos sobre 21 síntomas, su gravedad, duración, grado de afectación de la actividad y reincorporación al trabajo. Resultados : Respondieron 4673 profesionales sanita rios de 21 países, edad media de 47 años, 64% mujeres. El curso inicial fue asintomático en el 9%, síntomas leves en el 36%, síntomas moderados sin hospitalización en el 40% o con hospitalización en el 11%, y síntomas graves en el 1%. Los síntomas más prevalentes fueron fatiga (67%), insomnio (44%), ansiedad (42%), mialgia (41%) y anosmia (41%). La prevalencia se redujo a la mitad en los primeros 5 cinco meses, pero en muchos casos se prolongó durante más de un año. En el análisis multi variado los síntomas tendieron a agruparse en clusters (cognitivos, neuropsiquiátricos, cardiorrespiratorios, digestivos, otros). La necesidad de cambiar de área de trabajo fue del 16% y la falta de reincorporación al tra bajo del 7%, relacionadas con la mayor edad, el número de síntomas y la gravedad del curso inicial. Conclusión : En muchos casos la persistencia de los síntomas post COVID-19 puede ser prolongada y te ner un impacto laboral en los profesionales sanitarios, requiriendo la adopción de políticas específicas para reducir el daño.

Abstract Background : The evolution of post COVID-19 syn drome has been variable and we lack information on its impact on healthcare professionals. Methods : We conducted a survey through a social network in health professionals on post COVID-19 syn drome cases confirmed with PCR. In a web-based ques tionnaire, we asked about 21 symptoms, their severity, duration, degree of activity impairment and return to work. Results : 4673 health professionals from 21 countries responded, mean age of 47 years, 64% women. The initial course was asymptomatic in 9%, mild symptoms 36%, moderate symptoms without hospitalization 40% or with hospitalization 11%, and severe symptoms 1%. The most prevalent symptoms were fatigue (67%), insomnia (44%), anxiety (42%), myalgia (41%) and anosmia (41%). Prevalence dropped by half in the first 5 five months, but in many cases, it lasted for more than a year. In the mul 670 tivariate analysis, symptoms tended to be grouped into clusters (cognitive, neuropsychiatric, cardiorespiratory, digestive, others). The need to change the work area was 16% and lack of return to work 7%, related to older age, number of symptoms and severity of the initial course. Conclusion : in many cases the persistence of post- COVID symptoms can be prolonged and have an occu pational impact on healthcare professionals, requiring the adoption of specific policies to reduce harm.

Introducción: En el proceso de capacitación continua de los estudiantes de Medicina resulta necesario incorporar temas de actualidad; asimismo, es importante conocer los problemas para buscar soluciones con el apoyo de la ciencia. Objetivo: Diagnosticar el proceso formativo del estudiante de Medicina en cuanto a la detección de secuelas discapacitantes pos-COVID-19. Métodos: Se realizó un estudio observacional, descriptivo y transversal, con enfoque cualitativo, de 20 estudiantes del quinto año de la carrera de Medicina, pertenecientes a la Universidad de Ciencias Médicas de Camagüey, durante su estancia por la asignatura Salud Pública, desde julio hasta diciembre del 2022. Para tal propósito se diseñó y aplicó un instrumento evaluativo con dimensiones e indicadores. Resultados: Se halló que 50,0 % de dichos estudiantes se ubicó en el rango de edad de 21-26 años, mientras que 65,0 % correspondió al sexo femenino. La dimensión cognitiva fue evaluada de mal, pues 3 indicadores, de los 4 que la integraban, recibieron esa calificación; del mismo modo sucedió con la dimensión instrumental. En cambio, la dimensión actitudinal y sus 2 indicadores fueron calificados de bien. Conclusiones: Existieron insuficiencias en el proceso formativo del estudiante de Medicina, lo que obstaculiza su desempeño profesional. Sobre la base del diagnóstico realizado, se confirma como fortaleza el interés por la búsqueda de información relacionada con la detección de secuelas discapacitantes pos-COVID-19.

Introduction: In the continuous training process of medical students, it is necessary to incorporate current issues; likewise, it is important to know the problems to seek solutions with the science support. Objective: To diagnose the training process of medical students as for the detection of incapacitating sequelae post-COVID-19. Methods: An observational, descriptive and cross-sectional study, with qualitative approach, of 20 students from 5th year of Medicine career, belonging to the University of Medical Sciences in Camagüey was carried out during their stay for the Public Health subject, from July to December, 2022. For such a purpose it was designed and applied an evaluative instrument with dimensions and indicators. Results: It was found that 50.0% of these students were in the age range of 21-26 years, while 65.0% were female. The cognitive dimension was evaluated as bad because 3 indicators, of the 4 that made it up, received that qualification; the same happened with the instrumental dimension. On the other hand, the attitudinal dimension and its 2 indicators were qualified as good. Conclusions: Inadequacies existed in the training process of medical students, which block their professional performance. On the base of the diagnosis, the interest in searching for information related to the detection of post-COVID-19 incapacitating sequelae is confirmed as strength.

Analysis of pulmonary function in post-Covid-19 patients at a university hospital / Análise da função pulmonar de pacientes com síndrome pós-covid-19 em um hospital universitário

Objective: Evaluate the spirometry pattern of patients who persisted with respiratory symptoms after infection with SARS-Cov-2. Methods: Cross-sectional, observational, retrospective study in a single center, approved by the local Ethics Committee (registration number: 5,120,720). Patients who underwent spirometry due to Post-Covid Syndrome were evaluated to analyze the spirometric pattern presented. The following were collected: exam identification data, sex, age, symptom time, the need for mechanical ventilation, and quality of spirometry, in addition to the following exam parameters: FVC, FEV1, FEV1/FVC, FEV 25-75/FVC, and FEV 75, evaluating the Lower Limit of Normality, pre-bronchodilator and post-bronchodilator values. Results: Data from 72 patients were collected. Of these, 55.5% of patients had spirometry results within normal limits. The most frequent respiratory alteration was obstructive respiratory disorder, present in 29.2% of the patients. Conclusions: The presence of dyspnea in patients with normal spirometry may indicate further evaluation of lung function and other etiologies for dyspnea (AU).

Objetivo: Avaliar o padrão de espirometria de pacientes que persistiram com sintomas respiratórios após a infecção pelo SARS-CoV-2. Métodos: Estudo transversal, observacional e retrospectivo realizado em um único centro, aprovado pelo Comitê de Ética local (número do parecer: 5.120.720). Foram avaliados pacientes submetidos a espirometria devido à Síndrome Pós-Covid, a fim de analisar o padrão espirométrico apresentado. Os seguintes dados foram coletados: identificação do exame, sexo, idade, tempo de sintomas, necessidade de ventilação mecânica, qualidade da espirometria, além dos seguintes parâmetros do exame: CVF, VEF1, VEF1/CVF, VEF 25-75/CVF e VEF 75, avaliando o Limite Inferior da Normalidade, valores pré-broncodilatador e pós-broncodilatador. Resultados: Foram coletados dados de 72 pacientes. Destes, 55,5% apresentaram resultados espirométricos dentro dos limites normais. A alteração respiratória mais frequente foi o distúrbio ventilatório obstrutivo, presente em 29,2% dos pa-cientes. Conclusões: A presença de dispneia em pacientes com espirometria dentro da normalidade pode indicar uma avaliação adicional da função pulmonar, assim como outras etiologias para a dispneia (AU).

Frontal osteomyelitis post-COVID-19 associated mucormycosis

Rhino-orbito-cerebral mucormycosis (ROCM) is the most commonly noted form of mucormycosis, which is the most common secondary fungal infection following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Osteomyelitis is one of the rare sequelae of ROCM, frontal osteomyelitis being the rarest. We present four patients of coronavirus disease 2019 (COVID-19)-associated mucormycosis, who presented with frontal bone osteomyelitis after being treated for ROCM surgically and medically. This is the first case series highlighting this complication in post–COVID-19 mucormycosis patients and needs utmost attention as it can be life-threatening and can cause extreme facial disfiguration. All four patients are alive with salvage of the affected globe and vision being preserved in one patient. If identified early, disfiguration of face and intracranial extension can be avoided.

Pleural empyema after COVID-19: A delayed presentation

Globally, the number of coronavirus disease-2019 (COVID-19) cases and deaths shows a declining trend since a peak in January 2022. For now, the pandemic phase looks to be ended, until a severe new variant may trigger another wave. At present, in India, small pockets of COVID-19 cases and post-COVID complications are still being reported. Therefore, physicians should remain vigilant about the atypical presentations and potential delayed or long-term complications of SARS-CoV-2 infection, even in individuals who had a mild COVID-19 infection. Here, we present the case of a 52-year-old male patient with a history of hypertension, who is a non-smoker and developed culture-negative pleural empyema 7 months after a mild COVID-19 infection. The patient was successfully treated with antibiotics and early video-assisted thoracoscopic surgery

Diarrea en pacientes con COVID-19 y en el síndrome pos-COVID

La COVID-19, actual pandemia global, es causada por el coronavirus SARS-CoV-2, capaz de provocar un síndrome respiratorio agudo grave. Esta enfermedad es multisistémica y heterogénea, y no siempre se relaciona con la gravedad de la enfermedad pulmonar. De hecho, hasta un tercio de los pacientes puede presentar síntomas gastrointestinales como la diarrea -que se ha reportado como uno de los de mayor impacto-, tanto a consecuencia de la infección aguda como del síndrome pos-COVID-19. Además, los diversos esquemas de tratamientos que se indican pueden tener efectos sobre la diarrea, lo que la convierte en un motivo frecuente de consulta en la especialidad de gastroenterología. Los pacientes con enfermedades intestinales previas podrían ser más susceptibles a esta manifestación. Debido a esto, se realizó una búsqueda exhaustiva de artículos sobre el tema, publicados en revistas científicas de alta visibilidad, cubanas y extranjeras, con el objetivo de exponer las causas y características de la diarrea que se presenta en pacientes infectados con SARS-CoV-2. Se recopilaron 168 artículos, de los cuales 30 fueron utilizados en la presente revisión, que permitirá documentar a los médicos de asistencia, para un mejor manejo de la diarrea en pacientes en las fases mencionadas.

COVID-19, the current global pandemic, is produced by the SARS-CoV-2 coronavirus, capable of causing a severe acute respiratory syndrome. This disease is multi-systemic and heterogeneous, and is not always related to the severity of the lung disease. In fact, up to a third of the patients can show gastrointestinal symptoms like diarrhea-which has been reported as one of the most impactful-both as a consequence of the acute infection and of the post-COVID-19 syndrome. In addition, the various treatment schemes indicated may have effects on diarrhea, what makes them a frequent reason for consultation in the specialty of gastroenterology. Patients with previous intestinal diseases could be more susceptible to this manifestation. Due to this, an exhaustive search of articles on the theme, published in Cuban and foreign journals of high visibility, was carried out, with the aim of exposing the causes and characteristics of the diarrhea that occurs in patients infected by SARS-CoV-2. 168 articles were compiled, of which 30 were used in the current review, which will allow documenting the attending physician for a better management of diarrhea in patients in the mentioned phases.

Acute abducens nerve palsy with acute disseminated encephalomyelitis-like presentation following COVID-19 vaccination

We report two adult cases of abducens nerve palsy presenting immediately (within weeks) after they received the first dose of Covishield vaccination. Magnetic resonance imaging (MRI) of the brain obtained after the onset of diplopia demonstrated demyelinating changes. The patients had associated systemic symptoms. Post-vaccination demyelination typically known as acute disseminated encephalomyelitis (ADEM) associated with several vaccines is more common in children. Although the mechanism of the nerve palsy remains unclear, it is suspected to be related to the post-vaccine neuroinflammatory syndrome. Cranial nerve palsies and ADEM-like presentations may represent part of the neurologic spectrum following COVID-vaccination in adults, and ophthalmologists should be aware of these sequelae. Although cases of sixth nerve palsy following COVID vaccination are already reported, associated MRI changes have not been reported from India.

Post-COVID-19 pulmonary function tests in young health care workers in South Indian population – An observational study

Background: The risk of exposure to COVID-19 pandemic was substantially higher in frontline young health care workers. Due to repeated exposure while treating patients, the viral load is exponentially higher than the other population. Lungs being the earliest organ to be affected carry more risk of long-term morbidity. Thus, pulmonary function tests (PFTs) on post-COVID young health care workers provide a better view on the impact, recovery and residual effects. Aim and Objectives: The objectives of the study are as follows: (i) To assess the PFT in study group who have recovered from COVID-19 within the past 3 months; (ii) to compare their lung function with that of health care workers who have not been infected by COVID-19; and (iii) to determine obstructive, restrictive or mixed pulmonary changes if any in health care workers after 3 months of recovery. Materials and Methods: This study involving 50 young health care workers was done in the department of pulmonary medicine for a period of 4 months between January and April 2021. The study (mild COVID-19 positive) control group involved 25 participants each. PFT and diffusing capacity of lung for carbon monoxide (DLCO) were measured using computerized spirometer and single breath method. Results were analyzed using Shapiro–Wilk test, Independent sample t test, and Chi-square test. Results: A statistically significant difference was observed among the subjects of case and control group with respect to the level of FEV1 (P < 0.05), FEV1/Forced vital capacity (FVC) (P < 0.01), and FEF. FVC, Peak expiratory flow (PEF), forced expiratory time, DLCO, and peak inspiratory flow (PIF) were not statistically different between the study and control group. (P > 0.05).The 3-month post recovery values were high in males when compared to females, except for PIF, PEF and FEV1%. Conclusion: PFT and DLCO values were normal in young health care workers after 3 months of COVID-19 infection except for a decrease in FEF 25–75%.

Hallazgos en tomografía de tórax en el seguimiento a 4, 8 y 12 meses después de una neumonía grave por COVID-19 / Chest Tomography Findings in Follow-Up at 4, 8 and 12 Months after Severe COVID-19 Pneumonia

Introducción: el SARS-CoV-2 causa daño multiorgánico, con predilección al epitelio respiratorio. Los estudios de imagen en tórax han sido determinantes en muchas patologías y, durante la reciente pandemia, no fue excepción. En el seguimiento con tomografía de tórax post COVID-19 en varias series, se ha observado persistencia de lesiones al egreso y a lo largo de varios meses. El objetivo del trabajo fue describir los hallazgos tomográficos en pacientes con seguimiento hasta un año post egreso hospitalario por COVID-19 moderado-grave. Material y métodos: estudio retrospectivo, observacional, de pacientes hospitalizados por COVID-19 moderado-grave de marzo 2020 a marzo 2022 en el hospital del ISSSTE, Chiapas-México; con prueba RT-PCR SARS-CoV-2 positiva, TC de hospitalización y de seguimiento posterior al egreso (0-4 meses; 4-8 meses; 8-12 meses). Se utilizó la terminología de la sociedad Fleischner. Además, se evaluó la extensión por lóbulo afectado (>75%, 75-50%, 50-25%, <25%). Resultados: Se estudiaron 27 pacientes, 74% hombres, edad promedio 56 años. El patrón tomográfico predominante al ingreso fue el mixto con 56% y extensión pulmonar >75%; vidrio despulido 30% y 11% consolidación. Al cuarto y octavo mes el patrón mixto fue el más frecuente, al doceavo mes persistía en el 33% de los pacientes y en el 30% de los casos la tomografía fue normal. Conforme pasaron los meses, la extensión del daño fue limitándose. Conclusión: el seguimiento con tomografía en COVID-19 moderado-grave es indiscutible. Permite identificar con precisión el patrón tomográfico en los diferentes momentos de la enfermedad, optimizar el tratamiento y disminuir las secuelas.

Aged people's health needs in the face of long covid-19 and access to health services / Requerimientos de salud de adultos mayores frente a covid-19 prolongado y acceso a servicios de salud / Necessidades de saúde dos idosos frente à covid longa e o acesso aos serviços de saúde

ABSTRACT Objective: to understand the health needs of aged people who had long Covid-19 and details about access to the health system to meet these demands. Method: an exploratory and qualitative study carried out with 41 aged individuals who had Covid-19 in 2020 and presented residual symptoms 18 months after the infection. Data collection took place between February and July 2022 through semi-structured interviews via telephone calls. In the analysis, initial and focused coding analytical techniques were used and the conceptual basis was grounded on the Primary Health Care "Accessibility" attribute. Results: four categories emerged when analyzing the results, namely: Understanding the need for professional care; Recognizing the demands that led aged people to seek health services; Understanding availability of the services; and Analyzing payment capacity. Conclusion: the aged population has developed specific health demands related to long Covid-19, and public and private health services are heterogeneous in their approach to this new condition, as care based on guidelines proposed by official bodies is not unanimous in public and private services and Health Plan Operators.

RESUMEN Objetivo: averiguar las necesidades de salud de los adultos mayores que tuvieron Covid-19 prolongado y detalles del acceso al sistema de salud para suplir estos requerimientos. Método: estudio cualitativo y exploratorio realizado con 41 adultos mayores que tuvieron Covid-19 en 2020 y presentaron síntomas residuales 18 meses después de la infección. La recolección de datos tuvo lugar entre febrero y julio de 2022 por medio de entrevistas telefónicas semiestructuradas; en el análisis se utilizaron las técnicas analíticas de codificación inicial y focalizada y la base conceptual se fundamentó en el atributo "Accesibilidad" de la Atención Primaria de la Salud. Resultados: surgieron cuatro categorías en el análisis de los resultados, a saber: Comprender la necesidad de atención profesional; Reconocer los requerimientos que llevaron a los adultos mayores a procurar un servicio de salud; Percibir la disponibilidad de los servicios; y Analizar la capacidad de pago. Conclusión: la población anciana desarrolló requerimientos de la salud específicos relacionados con Covid-19 prolongado y los servicios de salud públicos y privados presentan cierta heterogeneidad en relación al enfoque de esta nueva condición, puesto que la atención basada en directrices propuestas por órganos oficiales no es unánime en los servicios públicos, privados y de Operadoras de Planes de Salud.

Conclusão: a população idosa desenvolveu demandas específicas de saúde relacionadas à Covid longa, e os serviços de saúde público e privado possuem heterogeneidade quanto à abordagem dessa nova condição, uma vez que o atendimento pautado em diretrizes propostas por órgãos oficiais não é unânime nos serviços públicos, privados e Operadoras de Plano de Saúde.

Post-acute COVID-19 in three doses vaccinated autoimmune rheumatic diseases patients: frequency and pattern of this condition

Abstract Background Data on post-acute COVID-19 in autoimmune rheumatic diseases (ARD) are scarce, focusing on a single disease, with variable definitions of this condition and time of vaccination. The aim of this study was to evaluate the frequency and pattern of post-acute COVID-19 in vaccinated patients with ARD using established diagnosis criteria. Methods Retrospective evaluation of a prospective cohort of 108 ARD patients and 32 non-ARD controls, diagnosed with SARS-CoV-2 infection (RT-PCR/antigen test) after the third dose of the CoronaVac vaccine. Post-acute COVID-19 (≥ 4 weeks and > 12 weeks of SARS-CoV-2 symptoms) were registered according to the established international criteria. Results ARD patients and non-ARD controls, balanced for age and sex, had high and comparable frequencies of ≥ 4 weeks post-acute COVID-19 (58.3% vs. 53.1%, p = 0.6854) and > 12 weeks post-acute COVID-19 (39.8% vs. 46.9%, p = 0.5419). Regarding ≥ 4 weeks post-acute COVID-19, frequencies of ≥ 3 symptoms were similar in ARD and non-ARD controls (54% vs. 41.2%, p = 0.7886), and this was also similar in > 12 weeks post-acute COVID-19 (68.3% vs. 88.2%, p = 0.1322). Further analysis of the risk factors for ≥ 4 weeks post-acute COVID-19 in ARD patients revealed that age, sex, clinical severity of COVID-19, reinfection, and autoimmune diseases were not associated with this condition (p > 0.05). The clinical manifestations of post-acute COVID-19 were similar in both groups (p > 0.05), with fatigue and memory loss being the most frequent manifestations. Conclusion We provide novel data demonstrating that immune/inflammatory ARD disturbances after third dose vaccination do not seem to be a major determinant of post-acute COVID-19 since its pattern is very similar to that of the general population.

Prevalencia del Diagnóstico Post-COVID-19 en el Centro Integral de Atención Provisional (FIGALI) durante el Primer Trimestre del 2021

Introducción: El Síndrome Post-COVID-19 ha sido la terminología mas acuñada para el diagnóstico de las secuelas que persisten por más de 3 meses posterior a la infección por el virus SARS-CoV-2. Objetivo: Determinar la prevalencia del Diagnóstico Post-COVID-19. Metodología: Estudio descriptivo, transversal, retrospectivo y observacional. El universo consiste en todos los pacientes mayores de edad hospitalizados que ameritaron oxigenoterapia en el Centro Integral de Atención Provisional para Pacientes Moderados COVID-19 (FIGALI) durante el primer trimestre de 2021. Se describen los datos demográficos, las comorbilidades, los principales síntomas persistentes y la asistencia a Clínicas Post-COVID.Resultados: Predominaron los mayores a 50 años (66%), con una estadía promedio de 10 días, ameritando la mayoría (79%) oxigenoterapia de bajo flujo (COVID-19 moderado), con distribución equitativa del sexo y mayoría de los encuestados tenía un mínimo de 5 meses de egresados. Las principales comorbilidades reportados fueron la hipertensión arterial (57%) y la diabetes mellitus (31%). La prevalencia del Diagnóstico Post-COVID-19 fue de 74% (131/177), siendo la fatiga, la tos y la disnea los principales síntomas reportados (45%, 32%, 29%) respectivamente. En el aspecto neuro-psiquiátrico se evidencia la ansiedad con un 18% y la depresión en 14% de los pacientes encuestados. Conclusiones: tres de cada cuatro pacientes que ameritaron oxigenoterapia, han persistido con al menos 1 síntoma luego de más de 5 meses de haber estado hospitalizado, siendo la fatiga el predominante. A pesar de la alta prevalencia descrita en este estudio, tan solo uno de cada cuatro pacientes, reporta haber acudido a Clínicas Post-COVID. (provisto por Infomedic International)

Introduction: Post-COVID-19 Syndrome has been the most coined terminology for the diagnosis of sequelae that persist for more than 3 months following SARS-CoV-2 virus infection. Objective: To determine the prevalence of post-COVID-19 diagnosis. Methodology: Descriptive, cross-sectional, retrospective, and observational study. The universe consists of all hospitalized patients of legal age who required oxygen therapy at the Centro Integral de Atención Provisional para Pacientes Moderados COVID-19 (FIGALI) during the first quarter of 2021. Demographic data, comorbidities, main persistent symptoms, and attendance to Post-COVID Clinics are described. Results: Predominantly those older than 50 years (66%), with an average stay of 10 days, most (79%) requiring low-flow oxygen therapy (moderate COVID-19), with equal distribution of sex and most respondents had a minimum of 5 months of discharge. The main comorbidities reported were hypertension (57%) and diabetes mellitus (31%). The prevalence of post-COVID-19 Diagnosis was 74% (131/177), with fatigue, cough and dyspnea being the main symptoms reported (45%, 32%, 29%) respectively. In the neuro-psychiatric aspect, anxiety was evident with 18% and depression in 14% of the patients surveyed. Conclusions: three out of four patients who required oxygen therapy persisted with at least one symptom more than 5 months after hospitalization, with fatigue being the predominant symptom. Despite the high prevalence described in this study, only one out of four patients reported having attended Post-COVID Clinics. (provided by Infomedic International)
