Résumé
ABSTRACT Purpose: To analyze the prevalence of lower urinary tract symptoms (LUTS) in patients who survived moderate and severe forms of COVID-19 and the risk factors for LUTS six months after hospitalization. Materials and Methods: In this prospective cohort study, patients were evaluated six months after hospitalization due to COVID-19. LUTS were assessed using the International Prostate Symptom Score. General health was assessed through the Hospital Anxiety and Depression Scale and the EQ5D-L5 scale, which evaluates mobility, ability to perform daily activities, pain and discomfort and completed a self-perception health evaluation. Results: Of 255 participants, 54.1% were men and the median age was 57.3 [44.3 - 66.6] years. Pre-existing comorbidities included diabetes (35.7%), hypertension (54.5%), obesity (30.2%) and physical inactivity (65.5%). One hundred and twenty-four patients (48.6%) had a hospital stay >15 days, 181 (71.0%) were admitted to an ICU and 124 (48.6%) needed mechanical ventilation. Median IPSS was 6 [3-11] and did not differ between genders. Moderate to severe LUTS affected 108 (42.4%) patients (40.6% men and 44.4% women; p=0.610). Nocturia (58.4%) and frequency (45.9%) were the most prevalent symptoms and urgency was the only symptom that affected men (29.0%) and women (44.4%) differently (p=0.013). LUTS impacted the quality of life of 60 (23.5%) patients with women more severely affected (p=0.004). Diabetes, hypertension, and self-perception of worse general health were associated with LUTS. Conclusions: LUTS are highly prevalent and bothersome six months after hospitalization due to COVID-19. Assessment of LUTS may help ensure appropriate diagnosis and treatment in these patients.
Résumé
La propuesta de extender hasta dos o tres años la observación de las consecuencias negativas de la infección por el virus SARS-CoV-2 se considera razonable, al alargar el tiempo de seguimiento de un padecimiento anteriormente desconocido. El propósito de esta comunicación es aportar nuevas consideraciones sobre una realidad: existen personas que no se han recuperado totalmente, en un tiempo prudencial, después de haber padecido de COVID-19. Se enfatiza que todavía estamos lejos de conocer todos los efectos biológicos que tendrá en el tiempo, la "inmunoestimulación masiva" de la pandemia en algunas personas. Se plantean algunas recomendaciones prácticas como a) Incluir el dato de haber padecido de COVID-19 en los antecedentes patológicos personales de los pacientes; b) Insistir en el seguimiento periódico de los enfermos, sobre todo los que manifiesten quejas de una convalecencia prolongada. Otras consecuencias, además de las netamente biológicas, son también importantes, entre ellas: mentales, sociales, laborales, económicas, consumo de servicios de salud y de servicios sociales. En relación a la pos-COVID siempre el reto estará vinculado a la aplicación de estrategias eficaces para la prevención y el control de la COVID-19. Pero si se presentan enfermos, el desafío consistirá en evitar las posibles causas de la pos-COVID, así como prevenir o atenuar la aparición de sus diferentes formas clínicas con conductas coherentes, en dependencia de las características de cada caso, así como atenuar, por todos, las consecuencias que se han provocado en las personas afectadas y para la sociedad.
The proposal to extend the negative consequences of infection with the SARS-CoV-2 virus observation to two or three years is considered reasonable, by lengthening the follow-up time of a previously unknown condition. This communication' purpose is to provide new considerations about a fact: there are people who have not fully recovered, in a reasonable time, after having suffered from COVID-19. It is emphasized that we are still far from knowing all the biological effects that the "massive immunostimulation" of the pandemic will have over time on some people. Some practical recommendations are proposed, such as a) Include the information of having suffered from COVID-19 in the patients' personal pathological history; b) Insist on periodic monitoring of patients, especially those who express complaints of prolonged convalescence. Other consequences, in addition to the purely biological ones, are also important, including: mental, social, labor, economic, consumption of health services and social services. In relation to post-COVID, the challenge will always be linked to the application of effective strategies for the COVID-19 prevention and control. But if illness people appear, the challenge will be to avoid the possible causes of post-COVID, as well as prevent or mitigate the appearance of its different clinical forms with coherent behaviors, depending on the characteristics of each case, as well as mitigate, by all, the consequences that have been caused to the affected people and to society.
Résumé
Caracterizada por sintomas que permanecem ou aparecem pela primeira vez em até três meses após a infecção pelo SARS-CoV-2, a COVID longa pode se manifestar de diferentes formas, inclusive entre casos não hospitalizados ou assintomáticos. Nesse sentido, este artigo apresenta um panorama da COVID longa no Brasil, com ênfase no diagnóstico, nos sintomas e nos desafios para a nova gestão da saúde. Foram utilizados dados de um estudo realizado com objetivo de investigar a COVID longa em pessoas acometidas pela COVID-19, com dados originais de um inquérito com indivíduos brasileiros adultos (18 anos ou mais) que tiveram COVID-19, coletados entre 14 de março e 14 de abril de 2022, por meio de questionário divulgado em redes sociais. O questionário abordou características sociodemográficas, histórico de infecções por COVID-19, vacinação contra a doença, investigação da situação de saúde e da qualidade de vida antes e após a COVID-19, além da busca e acesso a tratamento. Dos 1.728 respondentes, 720 foram considerados elegíveis para a análise. Desses, 496 (69%) tiveram COVID longa. Os indivíduos com COVID longa reportaram manifestações clínicas como ansiedade (80%), perda de memória (78%), dor generalizada (77%), falta de atenção (75%), fadiga (73%), queda de cabelo (71%), alterações de sono (70%), alterações de humor (62%), indisposição (60%) e dor nas articulações (59%). A maioria procurou os serviços de saúde durante e após a fase aguda de COVID-19 (94% e 80%, respectivamente), o que representa a necessidade de estruturar o sistema de saúde para atender esses pacientes.
Characterized by symptoms that remain or appear for the first time within three months of SARS-CoV-2 infection, long COVID can manifest itself in different ways, including in non-hospitalized or asymptomatic cases. Thus, this study offers an overview of long COVID in Brazil, especially of its diagnosis, symptoms, and challenges for new health management. Data from a study that investigated long COVID in people affected by COVID-19 were used. These original data stem from a survey with adult Brazilians (aged 18 years or older) who had COVID-19 that collected information from March 14 to April 14, 2022, by a questionnaire on social media. The questionnaire addressed sociodemographic characteristics, history of COVID-19 infections, vaccination against the disease, investigation of health status and quality of life before and after COVID-19, and search and access to treatment. Of the 1,728 respondents, 720 were considered eligible for analysis, of which 496 (69%) had long COVID. Individuals with long COVID reported clinical manifestations such as anxiety (80%), memory loss (78%), generalized pain (77%), lack of attention (75%), fatigue (73%), hair loss (71%), sleep changes (70%), mood swings (62%), malaise (60%), and joint pain (59%). Most sought health services during and after the acute phase of COVID-19 (94 and 80%, respectively), representing the need to structure the healthcare system for these patients.

Résumé
ABSTRACT. The repercussions of Long COVID demand specialised rehabilitation care. Interdisciplinary interventions in a 58-year-old patient were implemented to improve the clinical, motor and cognitive complaints associated with COVID-19. The rehabilitation team performed quantitative and qualitative evaluations in the initial phase and after 12 months of follow-up. The patient's neuropathic pain, ankle and foot muscle strength, gait pattern, general cognitive functioning, initiative, emotional expressiveness, processing speed, neuropsychiatric symptoms and quality of life improved. She demonstrated gains in metacognition and expanded the use of compensatory strategies, resuming her routine and professional activities, although still with signs of executive dysfunction. It is concluded that a rehabilitation program calibrated to the profile of the patient with Long COVID had positive effects on functionality and satisfaction with quality of life.
RESUMO. As repercussões da COVID Longa demandam atendimentos especializados de reabilitação. Intervenções interdisciplinares em paciente de 58 anos foram implementadas com o objetivo de melhorar as queixas clínicas, motoras e cognitivas associadas à COVID-19. A equipe de reabilitação realizou avaliações quantiqualitativas na fase inicial e após 12 meses de acompanhamento. A paciente evoluiu com melhora da dor neuropática, da força muscular de tornozelo e pé, do padrão de marcha, do funcionamento cognitivo geral, da iniciativa, da expressividade emocional, da velocidade de processamento, dos sintomas neuropsiquiátricos e da qualidade de vida (domínios físico e psicológico). Demonstrou ganhos na metacognição e ampliou o uso de estratégias compensatórias, retomando suas atividades rotineiras e profissionais, embora ainda com indícios de disfunção executiva. Conclui-se que um programa de reabilitação calibrado ao perfil do paciente com COVID longa trouxe efeitos positivos na funcionalidade e satisfação com a qualidade de vida.

ABSTRACT After the acute phase of COVID-19, many patients have persistent symptoms or develop sequelae, which leads them to seek physiotherapy rehabilitation services. Therefore, this study aimed to investigate the knowledge and experience of physiotherapists on the assessment and treatment of post-COVID-19 patients. The cross-sectional observational study was carried out with 73 physiotherapists using an online questionnaire about academic background, areas of expertise, knowledge about COVID-19, and knowledge and experience of assessment and treatment resources in post-COVID-19 rehabilitation, in addition to barriers to the care of these patients in the ambulatory care. Most physiotherapists had heard of post-COVID-19 syndrome, however, only 44% felt sufficiently informed about post-COVID-19 rehabilitation. There was a discrepancy between the degree of importance and experience with the frequency of use of assessment resources, especially the use of specific assessment instruments for skeletal muscle strength, mobility, and respiratory function, in addition to scales and questionnaires to assess disabilities, quality of life, and sleep quality. On the other hand, most reported the importance and had sufficient experience to treat post-COVID-19 patients using cheap and accessible resources. However, less than half use techniques related to respiratory muscle training and/or more sophisticated equipment. Thus, we conclude that most physiotherapists recognize the importance and report sufficient experience to assess and treat post-COVID-19 patients, however, there is a discrepancy between the assessment in the biopsychosocial context of the patient and the treatment process.
RESUMEN Terminada la fase aguda de la COVID-19, muchos pacientes presentan síntomas persistentes o desarrollan secuelas, lo que requiere servicios de rehabilitación fisioterapéutica. Ante esto, el objetivo de este estudio fue identificar los conocimientos y la experiencia de los fisioterapeutas respecto a la evaluación y el tratamiento de los pacientes post-COVID-19. Este estudio observacional transversal se llevó a cabo con 73 profesionales, mediante un cuestionario en línea sobre formación académica, áreas de actuación, conocimientos sobre la COVID-19 y experiencia con los recursos de evaluación y tratamiento en la rehabilitación post-COVID-19, además de las barreras para la atención de estos pacientes en el ámbito ambulatorio. Aunque la mayoría de los fisioterapeutas tenían algún conocimiento sobre el síndrome post-COVID-19, solamente el 44% de ellos se sentían suficientemente informados sobre la rehabilitación post-COVID-19. Se observa una discrepancia entre el grado de importancia y experiencia y la frecuencia de uso de los recursos de evaluación, especialmente el uso de herramientas de evaluación específicas para la fuerza muscular esquelética, la movilidad y la función respiratoria, además de escalas y cuestionarios para evaluar la discapacidad, la calidad de vida y la calidad del sueño. Por otro lado, la mayoría informó de la importancia de este tratamiento, afirmando tener experiencia suficiente para tratar a los pacientes post-COVID-19 utilizando recursos baratos y accesibles. Así, menos de la mitad de los profesionales utilizan técnicas vinculadas al entrenamiento de la musculatura respiratoria y/o equipos más sofisticados. Por lo tanto, se concluye que la mayoría de los fisioterapeutas reconocen la importancia de tratar a los pacientes post-COVID-19 y declaran tener experiencia suficiente para evaluarlos y tratarlos; sin embargo, hay una discrepancia entre el proceso de evaluación en el contexto biopsicosocial del paciente y el proceso de tratamiento.
RESUMO Após a fase aguda da COVID-19, muitos pacientes apresentam persistência de sintomas ou desenvolvem sequelas, o que os leva a procurar serviços de reabilitação fisioterapêutica. Sendo assim, o objetivo deste estudo foi investigar o conhecimento e a experiência de fisioterapeutas sobre a avaliação e tratamento de pacientes pós-COVID-19. O estudo observacional transversal foi realizado com 73 profissionais, por meio de um questionário online sobre formação acadêmica, áreas de atuação, conhecimento sobre a COVID-19 e experiência sobre recursos de avaliação e tratamento na reabilitação pós-COVID-19, além de barreiras para o atendimento desses pacientes no ambiente ambulatorial. A maioria dos fisioterapeutas já tinham ouvido falar da síndrome pós-COVID-19, no entanto, apenas 44% se sentiam suficientemente informados sobre a reabilitação pós-COVID-19. Houve uma discrepância entre o grau de importância e experiência e a frequência da utilização dos recursos de avaliação, principalmente o uso de instrumentos específicos de avaliação para força muscular esquelética, mobilidade e função respiratória, além de escalas e questionários para avaliar incapacidades, qualidade de vida e qualidade do sono. Em contrapartida, a maioria relatou a importância deste tratamento, alegando ter grau de experiência suficiente para tratar os pacientes pós-COVID-19 com a utilização de recursos baratos e acessíveis. Dessa forma, menos da metade dos profissionais realiza técnicas vinculadas ao treinamento muscular respiratório e/ou equipamentos mais sofisticados. Concluímos, então, que a maioria dos fisioterapeutas reconhece a importância do tratamento de pacientes pós-COVID-19 e relata uma experiência suficiente para avaliá-los e tratá-los, entretanto, há uma discrepância entre o processo de avaliação no contexto biopsicossocial do paciente e o processo de tratamento.
Résumé
ABSTRACT Post-acute COVID-19 syndrome, or long COVID, presents with persistent symptoms, including cough, dyspnea, and fatigue, extending beyond one month after SARS-CoV-2 infection. Cardiac complications such as chest pain and arrhythmias have raised concerns, with chronotropic incompetence (CI), an inadequate heart rate increase during exercise, emerging as a significant condition contributing to diminished exercise tolerance and quality of life. This study estimated the prevalence of CI and explored its association with aerobic capacity and physical activity levels in long COVID patients. A cross-sectional study was conducted at a private hospital in Sergipe, Brazil, involving 93 patients over 18 years old with persistent post-COVID-19 symptoms after confirmed SARS-CoV-2 infections. Exclusion criteria included beta-blocker use, inadequate respiratory exchange ratio, and inability to complete cardiopulmonary exercise testing (CPET). Clinical histories, CPET results, and chronotropic index calculation were used to identify CI, with logistic regression analyzing associated factors. Of the participants (mean age 45 years; average duration since COVID-19 diagnosis 120 days), 20.4% were diagnosed with CI. Logistic regression identified a strong association between CI and sedentary behavior (OR 11.80; 95% CI 2.54 to 54.78; p=0.001). Patients with CI showed lower predicted peak heart rates and maximal oxygen uptake. The prevalence of CI among long COVID patients in this study was approximately 20%, associated with decreased aerobic capacity and increased sedentary behavior. These findings highlight the need for timely diagnosis and therapeutic interventions, including cardiopulmonary rehabilitation, to enhance the quality of life in post-COVID patients with CI. The study's cross-sectional design and its specific context have limited causality inference and generalizability, underscoring the importance of further research in diverse settings.

Abstract Background The post-COVID-19 condition is a major modern challenge in medicine and has a high global impact on the health of the population. Objective To determine the main neurological and neuropsychiatric manifestations after acute COVID-19 infection in South American countries. Methods This is a systematic review study, registered on the PROSPERO platform following the PRISMA model. 4131 articles were found with the search strategies used. Neurological and neuropsychiatric manifestations were investigated in individuals three months or more after acute COVID-19 infection, and older than 18 years, including studies conducted in South American countries published between 2020 and 2022. Results Six studies (four from Brazil and two from Ecuador) were analyzed. Regarding the type of study: three were cohorts, two were case reports, and one was cross-sectional. The main outcomes found were new pain (65.5%) and new chronic pain (19.6%), new headache (39.1%), daily chronic headache (13%), paresthesia (62%), in addition to neuropsychiatric diseases, such as generalized anxiety disorder (15.1%), post-traumatic stress syndrome (13.4%), depression and anxiety (13.5%), suicidal ideation (10.1%), and several cognitive disorders. Conclusion Neurological and neuropsychiatric manifestations related to depression and anxiety, and cognition disorders are reported during the post-COVID-19 condition in South America. Symptoms associated with chronic pain appear to be associated with the condition. More studies on post-COVID-19 conditions are needed in the South America region.

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.
Résumé
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.

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.
Résumé
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.

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.

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.
Résumé
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.
Résumé
A síndrome pós-COVID-19 afeta pacientes independentemente da gravidade da doença. Os sintomas mais comuns são fadiga, cefaleia, déficit de atenção, dispneia e depressão. Para ajudar na reabilitação dos pacientes, a intervenção fisioterapêutica tem sido utilizada como estratégia. Objetivo: Analisar os efeitos de um programa de reabilitação fisioterapêutica na qualidade de vida, capacidade funcional, percepção de esforço, percepção da dor e força muscular, em indivíduos com a síndrome pós-COVID-19. Métodos: Trata-se de um estudo quase experimental, com 33 indivíduos, divididos em dois grupos: intervenção (GI) que recebeu um programa de reabilitação fisioterapêutica e controle (GC) que não recebeu. Os participantes foram avaliados antes e após o período de intervenção para força, por meio de dinamometria de preensão palmar; nível de dor, pela escala visual analógica; capacidade funcional, pelo teste de caminhada de seis minutos; percepção de esforço, através da escala modificada de BORG e qualidade de vida pelo instrumento SF-36. Resultados: Observou-se no GI aumento significativo (p<0,05) da qualidade de vida nos domínios de capacidade funcional, aspectos físicos e redução da dor e aumento da força de preensão palmar. Houve diferença significativa (p<0,05) entre os grupos para percepção de esforço nos momentos antes e após as intervenções. Para as demais variáveis não foram evidenciadas diferenças significativas. Conclusão: O programa de intervenção fisioterapêutica promoveu melhora dos domínios de capacidade funcional, aspectos físicos e da dor da qualidade de vida, e aumento da força de preensão palmar de indivíduos com sintomas da síndrome pós-COVID-19.
Post-COVID-19 syndrome affects patients regardless of the severity of the disease. The most common symptoms are fatigue, migraine, attention deficit, dyspnea, and depression. Physiotherapeutic intervention has been used as a strategy to aid the rehabilitation of patients. Objective: To analyze the effects of a physiotherapeutic rehabilitation program on quality of life, functional capacity, perceived exertion, perception of pain, and muscle strength in patients with post-COVID-19 syndrome. Methods: This is a quasi-experimental study with 33 participants, divided into two groups: an intervention group (IG) who received the physiotherapeutic rehabilitation program and a control group (CG) who did not. Participants were assessed for strength before and after the intervention period, using handgrip dynamometry and being assessed with a visual analog scale (VAS) for pain, the six-minute walk test (6MWT) for functional capacity, the BORG scale for exertion perception, and the SF-36 scale for quality of life. Results: A significant increase (p<0.05) in quality of life was observed in the IG in the SF-36 domains of physical functioning, physical role limitations, bodily pain, and increased handgrip strength. There was a significant difference (p<0.05) between the groups for perceived exertion before and after the intervention. No significant differences were found among the other variables. Conclusion: The physiotherapeutic intervention program improved the quality of life assessed with the SF-36 domains of physical functioning, physical role limitations, and bodily pain, and increased handgrip strength of patients with symptoms of post-COVID-19 syndrome.

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.
Résumé
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.
Résumé
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.
Résumé
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.
Résumé
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.
