Alpha-lipoic acid does not improve olfactory training results in olfactory loss due to COVID-19: a double-blind randomized trial

Abstract Objectives Olfactory loss is a recognized long-term dysfunction after Coronavirus Disease 2019 (COVID-19) infection. This investigation aimed to assess the effect of alpha-lipoic acid as an adjuvant treatment of olfactory training on the improvement of smell loss in post-COVID-19 patients. Methods This randomized controlled trial included 128 adult outpatients who had persistent smell loss for more than 3-months after COVID-19 infection. The participants were randomly allocated into two groups: the intervention treatment group, which received alpha-lipoic acid associated to olfactory training, and comparison treatment group, which received placebo pills associated to olfactory training. The participants were followed-up for 12-weeks. Olfactory dysfunction was assessed in terms of Visual Analog Scale (VAS), and the Connecticut Chemosensory Clinical Research Center (CCCRC) test for the Brazilian population. Results A total of 100 participants completed the follow-up period and were analyzed in this study. Both groups have improved CCCRC score (p= 0.000), olfactory threshold (p= 0.000), identification score (p= 0.000) and VAS score (p= 0.000) after 12-weeks follow-up. No significant differences were determined between the intervention and comparison treatment groups in CCCRC score (p= 0.63), olfactory threshold (p= 0.50), identification score (p= 0.96) and VAS score (p= 0.97). In all these criteria, comparison treatment group went slightly worse. At the endpoint of the study, the frequency of anosmia reduced to 2% in the intervention treatment group and to 7.8% in the comparison treatment group. Also, 16.8% of the intervention group' subjects, and 15.7% of comparison treatment group's patients reached normosmia. Conclusions Overall, there was a strongly significant difference in olfactory function between baseline and endpoint for both groups. However, based on the lack of significant difference between the intervention treatment and the comparison treatment groups in terms of olfactory changes, our study appoints that the alpha-lipoic acid is not better than olfactory training alone to treat olfactory loss after COVID-19. Level of evidence Level 2.

Síndrome pós-COVID-19 entre hospitalizados por COVID-19: estudo de coorte após 6 e 12 meses da alta hospitalar / Síndrome post-COVID-19 entre hospitalizados por COVID-19: estudio de cohorte tras 6 y 12 meses del alta hospitalaria / Post-COVID-19 syndrome among hospitalized COVID-19 patients: a cohort study assessing patients 6 and 12 months after hospital discharge

A síndrome pós-COVID-19 é um termo usado para descrever um conjunto diversificado de sintomas que persistem por mais de 12 semanas da infecção diagnosticada. O objetivo deste estudo foi analisar a síndrome pós-COVID-19 entre hospitalizados por COVID-19 após 6 e 12 meses da alta hospitalar. Trata-se de estudo de coorte ambidirecional, realizado com indivíduos que receberam alta em três dos principais hospitais da capital de Mato Grosso, Brasil, entre outubro e dezembro de 2021 e janeiro e março de 2022. Após coleta de dados em prontuários, os indivíduos foram entrevistados por telefone após 6 e 12 meses da alta hospitalar, sendo questionados sobre a presença de sintomas persistentes ou novos, para a avaliação de sua frequência segundo características sociodemográficas, econômicas, relativas à internação e condições de saúde. Dos 277 prontuários avaliados, 259 pacientes foram elegíveis para o estudo, 190 aos seis meses e 160 após 12 meses da alta hospitalar. Aos seis meses, 59% eram mulheres, 40% com 60 anos ou mais de idade e 87,4% referiram a presença de pelo menos um sintoma. Aos 12 meses, 58,7% eram mulheres, 37,5% com 30 a 49 anos e 67,5% referiram a presença de pelo menos um sintoma. A fadiga foi o sintoma mais comum após 6 e 12 meses de alta hospitalar (55,3% e 40,6%, respectivamente), seguido de problemas de memória (36,8%; 20%) e perda de cabelo (26,8%; 11,2%). Foi maior a prevalência de síndrome pós-COVID-19 entre indivíduos de maior faixa etária, menor renda, hipertensos, diabéticos e com maior gravidade durante a internação. Os fatores de risco da síndrome pós-COVID-19 contribuem para a compreensão dos efeitos a longo prazo e da importância do acompanhamento após a fase aguda da doença.

El síndrome post-COVID-19 es un término utilizado para describir un conjunto diversificado de síntomas que persisten durante más de 12 semanas de la infección diagnosticada. El objetivo fue analizar el síndrome post-COVID-19 entre hospitalizados por COVID-19 tras 6 y 12 meses del alta hospitalaria. Se trata de un estudio de cohorte ambidireccional, realizado con individuos que fueron dados de alta en tres de los principales hospitales de la capital de Mato Grosso, Brasil, entre octubre y diciembre de 2021 y enero y marzo de 2022. Tras recolectar los datos en registros médicos, se entrevistaron los individuos por teléfono tras 6 y 12 meses del alta hospitalaria, cuestionándoles sobre la presencia de síntomas persistentes o nuevos y evaluando su frecuencia conforme las características sociodemográficas, económicas, relacionadas con la hospitalización y condiciones de salud. De los 277 registros médicos evaluados, se eligieron 259 pacientes para el estudio, 190 a los 6 meses y 160 tras 12 meses del alta hospitalaria. A los 6 meses, el 59% eran mujeres, el 40% tenían 60 años o más y el 87,4% refirieron la presencia de al menos un síntoma. A los 12 meses, el 58,7% eran mujeres, el 37,5% tenían entre 30 y 49 años y el 67,5% refirieron la presencia de al menos un síntoma. La fatiga fue el síntoma más común tras 6 y 12 meses del alta hospitalaria (el 55,3% y el 40,6%, respectivamente), seguido de los problemas de memoria (el 36,8% y el 20%) y caída del pelo (el 26,8% y el 11,2%). La prevalencia de síndrome post-COVID-19 fue más alta entre los individuos de mayor edad, menor renta, hipertensos, diabéticos y con mayor gravedad durante la hospitalización. Los factores de riesgo del síndrome post-COVID-19 contribuyen para la comprensión de los efectos a largo plazo y de la importancia del seguimiento tras la fase aguda de la enfermedad.

Post-COVID-19 syndrome involves a variety of symptoms that last more than 12 weeks after COVID diagnosis. This study aimed to analyze post-COVID-19 syndrome among hospitalized COVID-19 patients 6 and 12 months after hospital discharge. This is an ambidirectional cohort study conducted with individuals who were discharged from three main hospitals in the capital of Mato Grosso State, Brazil, between October and December 2021 and January and March 2022. After data collection from medical records, the individuals were interviewed by telephone 6 and 12 months after hospital discharge, when they were asked about the presence of ongoing or new symptoms and when symptom frequency was evaluated according to sociodemographic and economic characteristics hospitalization, and health conditions. Of all 277 medical records evaluated, 259 patients were eligible to participate in the study, 190 patients six months after discharge and 160 patients 12 months after hospital discharge. At six months, 59% were female patients, 40% were aged 60 years or older, and 87.4% reported at least one symptom. At 12 months, 58.7% were female patients, 37.5% were aged 30 to 49 years, and 67.5% reported at least one symptom. Fatigue was the most common symptom 6 and 12 months after hospital discharge (55.3% and 40.6%, respectively), followed by memory problems (36.8%; 20%), and hair loss (26.8%; 11.2%). The prevalence of post-COVID-19 syndrome was higher among patients of older age, lower income, with hypertension, diabetes, and more severe infection during hospitalization. The risk factors for post-COVID-19 syndrome help understand the long-term effects and the importance of monitoring after the acute phase of the disease.

Long COVID: neurological manifestations - an updated narrative review / COVID longa: manifestações neurológicas - uma revisão narrativa atualizada

ABSTRACT. Infection with the SARS-CoV-2 virus can lead to neurological symptoms in the acute phase and in the Long COVID phase. These symptoms usually involve cognition, sleep, smell disorders, psychiatric manifestations, headache and others. This condition is more commonly described in young adults and women. This symptomatology can follow severe or mild cases of the disease. The importance of this issue resides in the high prevalence of neurological symptoms in the Long COVID phase, which entails significant morbidity in this population. In addition, such a condition is associated with high health care costs, with some estimates hovering around 3.7 trillion US dollars. In this review, we will sequentially describe the current knowledge about the most prevalent neurological symptoms in Long COVID, as well as their pathophysiology and possible biomarkers.

RESUMO. A infecção pelo vírus SARS-CoV-2 pode levar a sintomas neurológicos na fase aguda e na fase de COVID longa. Esses sintomas geralmente envolvem cognição, sono, distúrbios do olfato, manifestações psiquiátricas, dor de cabeça e outros. Esta condição é mais comumente descrita em adultos jovens e mulheres. A sintomatologia pode acompanhar casos graves ou leves da doença. A importância desta questão reside na elevada prevalência de sintomas neurológicos na fase de COVID longa, o que acarreta morbilidade significativa nesta população. Além disso, tal condição está associada a elevados custos de cuidados de saúde, com algumas estimativas em torno de 3,7 trilhões de dólares americanos. Nesta revisão, descrevemos sequencialmente o conhecimento atual sobre os sintomas neurológicos mais prevalentes na COVID longa, bem como sua fisiopatologia e possíveis biomarcadores.

Persistence of symptoms and lung function in mild cases of COVID-19 six months after infection: a cross-sectional study / Persistência de sintomas e função pulmonar em casos leves de COVID-19 seis meses após a infecção: um estudo transversal

ABSTRACT Objectives: To describe persistent symptoms and lung function in mild cases of COVID-19 six months after infection. Methods: Data collection was performed through a semi-structured questionnaire containing information on the participants' demographic and anthropometric data, the disease in the acute phase, and persistent symptoms six months after COVID-19 using spirometry and manovacuometry. Results: A total of 136 participants were evaluated, of whom 64% were male, with a mean age of 38.17 ± 14.08 years and a body mass index (BMI) of 29.71 ± 17.48 kg/m2. The main persistent symptoms reported were dyspnea on exertion (39.7%), memory loss (38.2%), and anxiety (48.5%). Considering lung function, the participants reached 88.87 ± 17.20% of the predicted forced vital capacity (FVC), 86.03 ± 22.01% of the forced expiratory volume in one second (FEV1), and 62.71 ± 25.04% of peak expiratory flow (PEF). Upon manovacuometry, 97.41 ± 34.67% of the predicted inspiratory force (Pimax) and 66.86 ± 22.97% of the predicted expiratory force (Pemax) were observed. Conclusions: Six months after COVID-19 infection, a reduction in PEF and MEP was observed. Among the most commonly reported persistent symptoms were fatigue, tiredness with the slightest exertion, anxiety and depression, memory loss, and deficits in concentration.

RESUMO Objetivos: Descrever os sintomas persistentes e a função pulmonar em casos leves de COVID-19 seis meses após a infecção. Métodos: A coleta de dados foi realizada por meio de um questionário semiestruturado contendo informações sobre dados demográficos e antropométricos dos participantes, a doença na fase aguda e os sintomas persistentes seis meses após a COVID-19, utilizando espirometria e manovacuometria. Resultados: Um total de 136 participantes foram avaliados, dos quais 64% eram do sexo masculino, com uma idade média de 38,17 ± 14,08 anos e índice de massa corporal (IMC) de 29,71 ± 17,48 kg/m2. Os principais sintomas persistentes relatados foram dispneia ao esforço (39,7%), perda de memória (38,2%) e ansiedade (48,5%). Considerando a função pulmonar, os participantes atingiram 88,87 ± 17,20% da capacidade vital forçada (CVF) prevista, 86,03 ± 22,01% do volume expiratório forçado no primeiro segundo (VEF1) e 62,71 ± 25,04% do pico de fluxo expiratório (PFE). Na manovacuometria, observou-se 97,41 ± 34,67% da força inspiratória prevista (Pimáx) e 66,86 ± 22,97% da força expiratória prevista (Pemáx). Conclusões: Seis meses após a infecção por COVID-19, observou-se uma redução no PFE e na PEM. Dentre os sintomas persistentes mais comumente relatados estavam fadiga, cansaço com o mínimo esforço, ansiedade e depressão, perda de memória e déficits de concentração.

Cardiorespiratory optimal point in post-COVID-19 patients: a cross-sectional study

ABSTRACT The varied clinical presentations of SARS-CoV-2 infection have raised concerns about long-term consequences, especially "long-COVID" or "post-COVID-19 syndrome." In this context, the cardiorespiratory optimal point (COP) within the Cardiopulmonary Exercise Test (CPET) emerges as a crucial metric for evaluating functional capacities and detecting cardiovascular and pulmonary anomalies post-COVID-19. This study aimed to assess COP values among post-COVID-19 patients and categorized them based on the initial severity of their disease. In this cross-sectional study conducted in the Northeast Brazil, 80 patients (26 females and 54 males) previously infected with SARS-CoV-2 underwent CPET. We clinically stratified patients into mild, moderate, or severe COVID-19 categories and assessed COP values and other cardiorespiratory metrics. We found differences in the predicted COP between patients with mild and severe COVID-19 (p=0.042). Additionally, patients with moderate and severe COVID-19 record had an average COP value exceeding 22. Other parameters, including respiratory exchange ratio, heart rate, and oxygen uptake efficiency slope, did not differ across the groups. Patients with a history of severe COVID-19 showed altered COP values, suggesting potential discrepancies in cardiovascular and respiratory system integration. The outcomes emphasize the importance of continuous monitoring and assessment of the cardiorespiratory domain for post-COVID-19 patients. Further research is needed to understand the relationship between elevated COP in post-severe COVID-19 and its long-term prognostic implications.

Cognitive impairment in post-acute COVID-19 syndrome: a scoping review / Comprometimento cognitivo na síndrome pós-COVID-19 aguda: uma revisão de escopo

Abstract Emerging studies indicate the persistence of symptoms beyond the acute phase of COVID-19. Cognitive impairment has been observed in certain individuals for months following infection. Currently, there is limited knowledge about the specific cognitive domains that undergo alterations during the post-acute COVID-19 syndrome and the potential impact of disease severity on cognition. The aim of this review is to examine studies that have reported cognitive impairment in post-acute COVID-19, categorizing them into subacute and chronic phases. The methodology proposed by JBI was followed in this study. The included studies were published between December 2019 and December 2022. The search was conducted in PubMed, PubMed PMC, BVS - BIREME, Embase, SCOPUS, Cochrane, Web of Science, Proquest, PsycInfo, and EBSCOHost. Data extraction included specific details about the population, concepts, context, and key findings or recommendations relevant to the review objectives. A total of 7,540 records were identified and examined, and 47 articles were included. The cognitive domains most frequently reported as altered 4 to 12 weeks after acute COVID-19 were language, episodic memory, and executive function, and after 12 weeks, the domains most affected were attention, episodic memory, and executive function. The results of this scoping review highlight that adults with post-acute COVID-19 syndrome may have impairment in specific cognitive domains.

Resumo Estudos emergentes indicam a persistência dos sintomas além da fase aguda da COVID-19. O comprometimento cognitivo foi observado em alguns indivíduos durante meses após a infecção. Atualmente, há pouco conhecimento sobre os domínios cognitivos específicos que sofrem alterações durante a síndrome pós-aguda da COVID-19 e o possível impacto da gravidade da doença na cognição. O objetivo desta revisão é examinar estudos que relataram comprometimento cognitivo na COVID-19 pós-aguda, categorizando-os em fases subaguda e crônica. A metodologia proposta pela Joanna Briggs Institute foi seguida neste estudo. Os estudos incluídos foram publicados entre dezembro de 2019 e dezembro de 2022. A busca foi realizada no PubMed, PubMed PMC, BVS - BIREME, Embase, SCOPUS, Cochrane, Web of Science, Proquest, PsycInfo e EBSCOHost. A extração de dados incluiu detalhes específicos sobre a população, os conceitos, o contexto e as principais descobertas ou recomendações relevantes para os objetivos da revisão. Um total de 7.540 registros foi identificado e examinado, e 47 artigos foram incluídos. Os domínios cognitivos mais frequentemente relatados como alterados de 4 a 12 semanas após a COVID-19 aguda foram linguagem, memória episódica e função executiva e, após 12 semanas, os domínios mais afetados foram atenção, memória episódica e função executiva. Os resultados dessa revisão de escopo destacam que adultos com síndrome pós-aguda da COVID-19 podem apresentar comprometimento em domínios cognitivos específicos.

Observaciones a partir del registro de evaluación cardiológica pos-COVID-19

Objetivo: Evaluar la prevalencia y características de los hallazgos cardiológicos "de Novo" (HCDN) en pacientes pos-COVID a partir de una secuencia diagnóstica cardiológica básica; asimismo, describir los resultados obtenidos en estos pacientes con los distintos métodos diagnósticos, detectar variables clínicas asociadas a la aparición de HCDN durante la evaluación y, por último, detectar el valor diagnóstico de distintos datos de la historia clínica (HC). Materiales y métodos: Se evaluó a pacientes >18 años que padecieron la COVID-19, internados o en su domicilio, mediante interrogatorio, examen físico, electrocardiograma (ECG), ecocardiograma (ECO), rutina de laboratorio y biomarcadores cardíacos entre los 30 y 120 días después del alta. Se incluyeron 246 pacientes (edad: 52 ± 13 años; mujeres: 48 %; COVID-19 leve [37 %], moderado [39 %], grave [24 %]). El 24 % de la población no presentaba síntomas en el momento de la evaluación; en los sintomáticos, la disnea fue lo más frecuente (28 %). El interrogatorio fue el método que reveló mayor porcentaje de sospecha (45 %). El examen físico, el ECG, el ECO y los biomarcadores fueron normales en el 60 %, 55 %, 75 % y 96 % de los pacientes, respectivamente. Resultados: Se detectaron HCDN en 62 pacientes (25,2 %): trastornos del ritmo en 42 (17 %) y disfunción ventricular en 20 (8 %). Cinco presentaron enfermedad coronaria; 6, miocarditis, y 2, valvulopatías. Además, se detectó tromboembolismo pulmonar (TEP) pos-COVID en 10 pacientes, de los cuales seis (2,4 %) debieron internarse nuevamente. Asimismo, en un análisis multivariado, las variables predictoras independientes de los HCDN fueron antecedentes de enfermedad pulmonar obstructiva crónica (EPOC), intervalo QTc > 440 ms, leucocitosis y complicación cardiológica intra-COVID (CCIC). La HC mostró baja sensibilidad y valor predictivo positivo para los HCDN. Conclusiones: Aunque los HCDN se observaron en un cuarto de la población, solo fueron relevantes en el 2 %. De acuerdo con estos datos, mediante esta secuencia diagnóstica y en este lapso, el énfasis debería estar puesto en los pacientes con antecedentes de EPOC y/o complicaciones cardiológicas durante la etapa aguda y/o intervalo QTc prolongado. Los síntomas pos-COVID tuvieron un valor limitado para el diagnóstico de arritmias o disfunción ventricular.

Objective: To evaluate the prevalence and characteristics of "de novo" cardiovascular findings (DNCFs) among post-COVID-19 patients based on a basic cardiovascular diagnostic procedure. Moreover, to describe the patients' results obtained by means of different diagnostic methods, to determine the clinical variables associated with DNCFs during the examination and, finally, to find out the diagnostic value of different data from medical records (MRs). Materials and methods: Patients aged > 18 years who had COVID-19 either at the hospital or at home were evaluated by clinical interviews, physical examination, electrocardiogram (EKG), echocardiogram, routine lab tests and cardiac biomarkers between 30 and 120 days after discharge. A total of 246 patients (age: 52 ± 13 years; women: 48 %; mild, moderate and severe COVID-19: 37 %, 39 % and 24 %, respectively) were included in the study. Twenty-four percent of the population were asymptomatic at the time of the evaluation. In those patients who developed symptoms, dyspnea was the most frequent one (28 %). Interviews were the method with the highest index of suspicion (45 %). Physical examination, EKG, echocardiogram and biomarkers showed normal values among 61 %, 60 %, 75 % and 96 % of the patients, respectively. Results: DNCFs were found in 62 patients (25.2 %): heart rhythm disorders in 42 (17 %) and ventricular dysfunction in 20 (8 %). Five patients had coronary artery disease, six had myocarditis and two had valvular heart disease. In addition, post-COVID-19 pulmonary embolism (PE) was detected in 10 patients, six of whom (2.4 %) had to be rehospitalized. Furthermore, in a multivariate analysis, the independent predictive variables of DNCFs were prior history of chronic obstructive pulmonary disease (COPD), QTc > 440 msec, leukocytosis and intra-COVID-19 cardiovascular complication. MRs showed both low sensitivity and positive predictive value for DNCFs. Conclusions: Although DNCFs were observed in 25 % of the population, only 2 % were significant. According to the data collected from this diagnostic procedure and in this time frame, special attention should be paid to patients with prior history of COPD and/or cardiovascular complications during the acute stage and/or prolonged QTc interval. Post-COVID-19 symptoms were of limited value for the diagnosis of arrhythmias or ventricular dysfunction.

Prevalence and Determinants of Long COVID among the COVID-19 Survivors: A Cross-sectional Study from A Rural Area of Maharashtra

Background: Most patients infected with the COVID-19 virus may experience long-term effects from COVID-19 infection, known as post-COVID or long COVID conditions. Long COVID may last for weeks, months or years and may limit ones day to day activities and needs health care. Aim & Objective: To study the prevalence and risk factors of long COVID among the COVID-19 survivors of a rural area of Maharashtra. Methods and Material: A Community-based cross-sectional study was conducted in adult subjects residing in Chanai village from Maharashtra who have had a history of COVID-19 and have passed more than 3 months since the diagnosis from May 2022 to June 2022. The interview of the study participants was conducted with the help of a pre-designed, semi-structured questionnaire for data collection. Statistical Analysis: Data was analyzed using Microsoft Excel 2010, Open EPI-Info version 3.01 updated on 2013/04/06. Data was presented in tables, graphical format, frequencies and percentages and the statistical association was shown using the chi- square test. Results: The majority of participants were males (59%), from 19 to 39 years of age group (57%), having fever as presenting symptom (83%), with mild COVID (13%), and required hospitalization (53%). Long COVID was associated with the elderly age group, male sex (27.1%), severe COVID presentation (88.2%) after 12 weeks, and those required intubation (80%). Conclusion: The prevalence of long COVID was 17.5%. Determinants associated with long COVID were the elderly age group, male sex, severe COVID presentation and who required intubation.

Lung and physical function in post COVID-19 and clinical and functional associations: a cross-sectional study in Brazil

SUMMARY OBJECTIVE: The purpose of this study was to assess exercise capacity, lung and physical function in COVID-19 survivors, and the association of lesion-level characteristics assessed by chest computed tomography, probable sarcopenia, and percentage of diffusing capacity of the lung for carbon monoxide with clinical and functional variables. METHODS: This study was conducted in Salvador, Bahia, Brazil. All patients had a laboratory-confirmed SARS-CoV-2 infection. The sociodemographic characteristics, COVID-19 exposure history, pulmonary function, computed tomography, and functionality of the participants between 1 and 3 months of diagnosis of the disease were collected. RESULTS: A total of 135 patients after COVID-19 recovery were included in this study. Probable sarcopenia, reduction in percentage of diffusing capacity of the lung for carbon monoxide, and a lower 6-min walk distance were observed after COVID-19 infection. Computed tomography>50% was associated with a longer length of stay and a lower percentage of diffusing capacity of the lung for carbon monoxide. Probable sarcopenia diagnosis was associated with a worse percentage of the predicted 6-min walk distance in relation to the predicted, absolute 6-min walk distance (m), percentage of diffusing capacity of the lung for carbon monoxide, and percentage of total lung capacity. CONCLUSION: Muscle disability and lung dysfunction are common in COVID-19 survivors. Hospitalization was associated with the worst muscle force and diffusing capacity of the lung for carbon monoxide. Computed tomography characteristics could be a marker of prolonged hospital stay after the acute phase of COVID-19. Additionally, the probable diagnosis of sarcopenia could be a marker of impact on walking distance. These results highlight the need for long-term follow-up of those patients and rehabilitation programs.

Role of the one-minute sit-to-stand test in the diagnosis of post COVID-19 condition: a prospective cohort study / Papel do teste de se sentar e levantar durante um minuto no diagnóstico de síndrome pós-COVID-19: estudo prospectivo de coorte

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

RESUMO Objetivo: Analisar a relação entre parâmetros do teste de se sentar e levantar durante um minuto (TSL1) e o diagnóstico de síndrome pós-COVID-19 em uma coorte de pacientes que anteriormente apresentaram COVID-19. Métodos: Estudo prospectivo de coorte de pacientes com síndrome pós-COVID-19 encaminhados para realizar pletismografia corporal em um hospital universitário terciário. A síndrome pós-COVID-19 foi definida conforme os critérios atuais da OMS. Resultados: Foram analisados 53 pacientes. Destes, 25 (47,2%) preencheram os critérios clínicos de síndrome pós-COVID-19. A FC foi menor nos pacientes com síndrome pós-COVID-19 do que naqueles sem a síndrome 30 s após o início do TSL1 (86,2 ± 14,3 bpm vs. 101,2 ± 14,7 bpm; p < 0,001) e no fim do teste (94,4 ± 18,2 bpm vs. 117,3 ± 15,3 bpm; p < 0,001). A relação entre a FC no fim do TSL1 e a FC máxima prevista para a idade (FCfim/FCmáx) foi menor nos pacientes com síndrome pós-COVID-19 (p < 0,001). A relação FCfim/FCmáx < 62,65% apresentou sensibilidade de 78,6% e especificidade de 82,0% para síndrome pós-COVID-19. A média da SpO2 no fim do TSL1 foi menor nos pacientes com síndrome pós-COVID-19 do que naqueles sem a síndrome (94,9 ± 3,6% vs. 96,8 ± 2,4%; p = 0,030). Os pacientes com síndrome pós-COVID-19 realizaram menos repetições durante o TSL1 do que os sem a síndrome (p = 0,020). Conclusões: SpO2 e FC mais baixas no fim do TSL1 e FC mais baixa 30 s após o início do teste apresentaram relação com síndrome pós-COVID-19. No contexto clínico apropriado, a relação FCfim/FCmáx < 62,65% deve alertar para a possibilidade de síndrome pós-COVID-19.

Impact of impaired pulmonary function on clinical outcomes in survivors of severe COVID-19 without pre-existing respiratory disease / Impacto do comprometimento da função pulmonar nos desfechos clínicos em sobreviventes de COVID-19 grave sem doenças respiratórias preexistentes

ABSTRACT Objective: To investigate the impact of impaired pulmonary function on patient-centered outcomes after hospital discharge due to severe COVID-19 in patients without preexisting respiratory disease. Methods: This is an ongoing prospective cohort study evaluating patients (> 18 years of age) 2-6 months after hospital discharge due to severe COVID-19. Respiratory symptoms, health-related quality of life, lung function, and the six-minute walk test were assessed. A restrictive ventilatory defect was defined as TLC below the lower limit of normal, as assessed by plethysmography. Chest CT scans performed during hospitalization were scored for the presence and extent of parenchymal abnormalities. Results: At a mean follow-up of 17.2 ± 5.9 weeks after the diagnosis of COVID-19, 120 patients were assessed. Of those, 23 (19.2%) reported preexisting chronic respiratory diseases and presented with worse lung function and exertional dyspnea at the follow-up visit in comparison with their counterparts. When we excluded the 23 patients with preexisting respiratory disease plus another 2 patients without lung volume measurements, a restrictive ventilatory defect was observed in 42/95 patients (44%). This subgroup of patients (52.4% of whom were male; mean age, 53.9 ± 11.3 years) showed reduced resting gas exchange efficiency (DLCO), increased daily-life dyspnea, increased exertional dyspnea and oxygen desaturation, and reduced health-related quality of life in comparison with those without reduced TLC (50.9% of whom were male; mean age, 58.4 ± 11.3 years). Intensive care need and higher chest CT scores were associated with a subsequent restrictive ventilatory defect. Conclusions: The presence of a restrictive ventilatory defect approximately 4 months after severe COVID-19 in patients without prior respiratory comorbidities implies worse clinical outcomes.

RESUMO Objetivo: Investigar o impacto do comprometimento da função pulmonar nos desfechos centrados no paciente após a alta hospitalar em pacientes sem doenças respiratórias preexistentes que foram hospitalizados em virtude de COVID-19 grave. Métodos: Trata-se de um estudo prospectivo de coorte em andamento, no qual pacientes com COVID-19 grave (com idade > 18 anos) são avaliados 2-6 meses depois da alta hospitalar. Avaliamos os sintomas respiratórios, a qualidade de vida relacionada à saúde, a função pulmonar e a distância percorrida no teste de caminhada de seis minutos. A definição de distúrbio ventilatório restritivo foi CPT abaixo do limite inferior da normalidade na pletismografia. As imagens de TC de tórax realizadas durante a hospitalização foram avaliadas quanto à presença e extensão de alterações parenquimatosas. Resultados: Em média 17,2 ± 5,9 semanas depois do diagnóstico de COVID-19, foram avaliados 120 pacientes. Destes, 23 (19,2%) relataram doenças respiratórias crônicas preexistentes e apresentaram pior função pulmonar e maior dispneia aos esforços na consulta de acompanhamento quando comparados aos outros participantes. Quando excluímos os 23 pacientes com doenças respiratórias preexistentes e mais 2 pacientes (sem medidas de volumes pulmonares), observamos distúrbio ventilatório restritivo em 42/95 pacientes (44%). Esse subgrupo de pacientes (52,4% dos quais eram do sexo masculino, com média de idade de 53,9 ± 11,3 anos) apresentou menor eficiência das trocas gasosas (DLCO), maior dispneia na vida diária e dessaturação de oxigênio ao exercício e redução da qualidade de vida relacionada à saúde em comparação com aqueles sem redução da CPT (50,9% dos quais eram do sexo masculino, com média de idade de 58,4 ± 11,3 anos). A necessidade de terapia intensiva e pontuações mais altas no escore de alterações parenquimatosas na TC de tórax apresentaram relação com distúrbio ventilatório restritivo subsequente. Conclusões: A presença de distúrbio ventilatório restritivo aproximadamente 4 meses depois da COVID-19 grave em pacientes sem comorbidades respiratórias prévias implica piores desfechos clínicos.

Prevalence of persistent symptoms after having COVID-19 in a cohort in Suriname / Prevalencia de síntomas persistentes tras la COVID-19 en una cohorte en Suriname / Prevalência de sintomas persistentes após COVID-19 em uma coorte no Suriname

ABSTRACT Objectives. To determine the prevalence of persistent symptoms after having coronavirus disease 2019 (COVID-19) in a cohort in Suriname, and assess the factors associated with long COVID. Methods. A sample of adults 18 years and older who were registered 3-4 months previously in a national database because of a positive COVID-19 test were selected. They were interviewed about socioeconomic characteristics, pre-COVID-19 health status and lifestyle, and symptoms during and after COVID-19. A subset of participants underwent a physical examination to determine body mass index, waist circumference, cardiovascular parameters, lung function, and functionality. Results. A total of 106 participants (mean age 49 (standard deviation 15) years; 62.3% female) were interviewed, of whom 32 were physically examined. The greatest proportion of participants was of Hindustani descent (22.6%). Overall, 37.7% of participants were physically inactive, 26.4% had hypertension or diabetes mellitus, and 13.2% had been previously diagnosed with heart disease. Most participants (56.6%) had experienced mild COVID-19 and 14.2% had experienced severe COVID-19. A large proportion (39.6%) had experienced at least one persistent symptom after recovery from acute COVID-19 and more women were affected (47.0% of women versus 27.5% of men). Fatigue and alopecia were the most common symptoms, followed by dyspnea and sleep disturbance. Differences were observed between ethnic groups. Based on physical examination, 45.0% of the subset was obese and 67.7% had very high waist-circumference. Conclusions. About 40% of the cohort had at least one persistent symptom 3-4 months after having had COVID-19, with differences observed by sex and ethnic group.

Challenges and construction of knowledge by nurses in care for people with post-covid-19 syndrome / Desafíos y construcción del conocimiento por parte de los enfermeros en la asistencia a personas con síndrome post-covid-19 / Desafios e construção de conhecimentos por enfermeiros na assistência às pessoas com síndrome pós-covid-19

ABSTRACT OBJECTIVE: to understand how nurses describe the challenges and construction of knowledge related to the care provided to people with post-COVID-19 syndrome. METHOD: this is qualitative-descriptive research, guided by the social constructionist perspective, carried out with seven nurses in a 24-hour Emergency Care Unit located in Minas Gerais. Data were collected from March to June 2022 through recorded semi-structured interviews. Data analysis took place through the transcription of interviews, followed by a curious reading of the material and definition of categories, step-by-step, anchored by social constructionism. The theoretical framework was composed of the set of authors who helped in the analysis and discussion of the categories constructed to respond to the study objectives. RESULTS: four categories emerged from the interviews, namely: 1) Initial reflexes of the pandemic, in which nurses' feelings of fear, concern and insecurity were evidenced; 2) COVID-19 traces, of which the respiratory sequels caused by the disease stood out; 3) Knowledge about post-COVID-19 syndrome, which detected lack of knowledge about signs and symptoms and nursing care, due to lack of training and use of protocols; 4) Care for post-COVID-19 syndrome, which highlighted the lack of knowledge about referring people to rehabilitation services. CONCLUSION: despite the lack of protocols and training provided by the institution, nursing professionals provided assistance care on knowledge provided by their experiences and the exchange of experiences with other collaborators.

RESUMEN OBJETIVO: comprender cómo los enfermeros describen los desafíos y la construcción de conocimientos relacionados con el cuidado prestado a las personas con síndrome post-COVID-19. MÉTODO: investigación cualitativa-descriptiva, guiada por la perspectiva construccionista social, realizada con siete enfermeros en una Unidad de Atención de Emergencia 24 horas, ubicada en Minas Gerais. Los datos fueron recolectados de marzo a junio de 2022 a través de entrevistas semiestructuradas grabadas. El análisis de datos se realizó a través de la transcripción de entrevistas, seguida de una lectura curiosa del material y definición de categorías, paso a paso anclado en el construccionismo social. El marco teórico estuvo compuesto por el conjunto de autores, quienes ayudaron en el análisis y discusión de las categorías construidas para responder a los objetivos del estudio. RESULTADOS: de las entrevistas surgieron cuatro categorías, a saber: 1) Reflexiones iniciales de la pandemia, en las que se evidenciaron los sentimientos de miedo, preocupación e inseguridad de las enfermeras; 2) Los rastros del COVID-19, de los cuales se destacaron las secuelas respiratorias provocadas por la enfermedad; 3) Conocimiento sobre el síndrome post-COVID-19, que detectó falta de conocimiento sobre signos y síntomas y cuidados de enfermería, por falta de capacitación y uso de protocolos y; 4) Atención al síndrome post-COVID-19, que destacó el desconocimiento sobre la derivación de personas a los servicios de rehabilitación. CONCLUSIÓN: incluso, ante la falta de protocolos y capacitación brindada por la institución, los profesionales de enfermería brindaron asistencia a partir del conocimiento brindado por sus experiencias y el intercambio de experiencias con otros colaboradores.

A análise dos dados ocorreu por meio da transcrição das entrevistas, seguida pela leitura curiosa do material e definição de categorias, passo-a-passo ancorado pelo construcionismo social. O referencial teórico foi composto pelo conjunto de autores, que auxiliaram na análise e discussão das categorias construídas para responder aos objetivos do estudo. RESULTADOS: emergiram das entrevistas quatro categorias, a saber: 1) reflexos iniciais da pandemia, na qual foram evidenciados sentimentos de medo, preocupação e insegurança das enfermeiras; 2) os rastros da COVID-19, dos quais, destacaram-se as sequelas respiratórias ocasionadas pela doença; 3) o saber sobre a síndrome pós-COVID-19, que detectou o desconhecimento acerca dos sinais e sintomas e assistência de enfermagem, devido à falta de treinamentos e uso de protocolos e; 4) atendimento à síndrome pós-COVID-19, que destacou a falta de conhecimento acerca do encaminhamento das pessoas aos serviços de reabilitação. CONCLUSÃO: mesmo diante da falta de protocolos e treinamentos proporcionados pela instituição, as profissionais de enfermagem prestaram assistência baseada no conhecimento proporcionado pelas suas vivências e pela troca de experiências com outros colaboradores.

Long COVID-19 syndrome associated with Omicron XBB.1.5 infection: a case report

BACKGROUND There is interest in lingering non-specific symptoms after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, referred to as Long coronavirus disease 2019 (Long COVID-19). It remains unknown whether the risk of Long COVID-19 is associated with pre-existing comorbidities or initial COVID-19 severity, including infections due to new Omicron lineages which predominated in 2023. OBJECTIVES The aim of this case report was to characterize the clinical features of acute XBB.1.5 infection followed by Long COVID-19. METHODS We followed a 73-year old female resident of Rio de Janeiro with laboratory-confirmed SARS-CoV-2 during acute infection and subsequent months. The SARS-CoV-2 lineage was determined by genome sequencing. FINDINGS The participant denied comorbidities and had completed a two-dose vaccination schedule followed by two booster doses eight months prior to SARS-CoV-2 infection. Primary infection by viral lineage XBB.1.5. was clinically mild, but the participant subsequently reported persistent fatigue. MAIN CONCLUSIONS This case demonstrates that Long COVID-19 may develop even after mild disease due to SARS-CoV-2 in fully vaccinated and boosted individuals without comorbidities. Continued monitoring of new SARS-CoV-2 lineages and associated clinical outcomes is warranted. Measures to prevent infection should continue to be implemented including development of new vaccines and antivirals effective against novel variants.

Guillain Barré syndrome in the paediatric population. Consequence of active infection or long Covid?

Background: Guillain-Barre syndrome is a polyradiculoneuropathy that has been associated with infectious diseases as triggers. There is currently little medical evidence exploring the relationship between the development of Guillain-Barre syndrome caused by SARS-CoV-2 infection and long Covid. Objective: To synthesize the medical evidence that describes the relationship between post Covid syndrome and Guillain-Barre syndrome in the paediatric population. Methodology: A scoping review was developed using Scopus and PubMed databases, including analytical and/or descriptive experimental and observational studies. Results: The main clinical manifestations presented by paediatric patients were distal and ascending weakness in the lower limbs and myalgia. The diagnostic approach was based on clinical findings, imaging findings on spinal magnetic resonance and electromyography. The therapeutic strategy is based on the use of intravenous human immunoglobulins. Conclusion: Guillain-Barre syndrome is a frequent disease in the paediatric population with active SARS-CoV-2 infection or in survivors, however, it is necessary to encourage further clinical studies that increase the medical literature that describes this association.

Introducción: El síndrome de Guillain-Barré es una polirradiculoneuropatía que se ha asociado con enfermedades infecciosas como desencadenantes. En la actualidad es escasa la evidencia médica que explore la relación entre el desarrollo del síndrome de Guillain-Barré causado por la infección por SARS-CoV-2 y la COVID prolongada. Objetivo: Sintetizar la evidencia médica que describe la relación entre el síndrome pos-COVID y el síndrome de Guillain-Barré en la población pediátrica. Metodología: Se realizó una revisión exploratoria utilizando las bases de datos de Scopus y PubMed, incluyendo estudios experimentales y observacionales analíticos o descriptivos. Resultados: Las principales manifestaciones clínicas presentadas por los pacientes fueron debilidad distal y ascendente en miembros inferiores y mialgias. El enfoque diagnóstico se apoyó en los hallazgos clínicos, hallazgos imagenológicos por resonancia magnética de columna y electromiografía. La estrategia terapéutica se basó en el uso de inmunoglobulinas humanas intravenosas. Conclusión: El síndrome de Guillain-Barré es una enfermedad frecuente en la población pediátrica con infección activa por SARS-CoV-2 o en sobrevivientes, sin embargo, es necesario incentivar el desarrollo de estudios clínicos que incrementen la literatura médica que describe esta asociación.
