Surviving critical COVID-19: How functionality, physical, mental and cognitive outcomes evolve?

PURPOSE: To analyze the long-term consequences of critical COVID-19, regarding physical, mental, cognitive and functional impairments, and to describe its evolution through time. METHODS: Prospective cohort study, with consecutive inclusion of patients admitted due to SARS-CoV-2 to intensive care units(ICU) of a tertiary-care center, between May/2020 and September/2021. All included patients were included in Physical and Rehabilitation Medicine(PRM) inpatient programs during ICU stay. Eligible patients were evaluated on PRM appointments 6 and 12 months after ICU discharge. In each visit, physical examination and a predefined set of scales were applied, aiming to comprehensively evaluate the three domains (physical, mental and cognitive) of post-intensive care syndrome and the patients' functionality. Statistical analysis encompassed descriptive and univariate analysis. RESULTS: A total of 42 patients were included: 66.7% males, mean age of 62 yo. In the physical domain, 6 months after ICU discharge, there was a significant reduction in quality of life (p-value = 0.034), muscle strength (p-value = 0.002), gait ability (p-value<0.001) and balance (p-values<0.001) and increased fatigue levels (p-value = 0.009), in comparison with reference values. Yet, a significative positive evolution was observed in all referred subdomains (p-values<0.05). Nevertheless, 12 months after discharge, muscle strength (p-value = 0.001), gait (p-value<0.001) and balance (p-value<0.001) were still significantly compromised. Regarding the mental domain, both at 6 and 12 months after discharge, the levels of anxiety and depression were significantly increased (p-values<0.001). Nonetheless, a positive evolution was also found (p-values<0.02). Cognitive performance was significantly impaired in comparison with reference values, both at 6 and 12 months (p-value<0.001). Yet, a global improvement was also depicted (p-value = 0.003). Six months after ICU discharge, 54.8% were autonomous in activities of daily living, a value that improved to 74.0% in the subsequent 6 months (p-value = 0.002). CONCLUSION: Critical COVID-19 survivors present significant physical, mental and cognitive impairments 6 and 12 months after ICU discharge, despite their positive evolution through time.

Socioeconomic Inequalities and Predictors of Cardiac Rehabilitation Referral: Real-World Evidence.

OBJECTIVE: The aim of the study is to identify factors associated with cardiac rehabilitation referral after an acute coronary syndrome at a university hospital. DESIGN: We analyzed 2814 hospitalizations due to acute coronary syndrome between 2017 and 2019 in Centro Hospitalar São João. The hospital's morbidity database was used to retrieve patient information. Cardiac rehabilitation referral and participation were identified from administrative databases and clinical records. Socioeconomic data were obtained from municipality of residence-level data rather than patient-specific data. RESULTS: Of 2814 hospitalizations, 72% (2028 cases) were eligible for cardiac rehabilitation. Mean age was 65.2 ± 13.4 yrs; 72% men, 33% diabetic, 57.1% hypertensive, and 63.6% dyslipidemic. Cardiac rehabilitation referral rate was low, at 18.8%, with 42 (11.0%) not attending cardiac rehabilitation and 39 (10.2%) dropping out. Females (odds ratio = 0.72 [95% confidence interval = 0.52-1.00]), older patients (odds ratio = 0.57 [0.42-0.77]; 55-64 vs. <55 yrs), and those coming from lower-income municipalities (odds ratio = 0.53 [0.41-0.69], below median vs. above median) with lower education level (odds ratio = 0.70 [0.54-0.92]; ≤4 vs. >4 yrs) were less likely to be referred to cardiac rehabilitation. CONCLUSIONS: There is a need for new strategies to promote cardiac rehabilitation in disadvantaged groups, as sex, age, and socioeconomic inequities in access to cardiac rehabilitation remain unresolved.

The PRINCOVID Retrospective Study: A Predictive Model of Pressure Injuries for Critical COVID-19 Patients.

OBJECTIVE: The aim of the study is to characterize pressure injuries, identify risk factors, and develop a predictive model for pressure injuries at intensive care unit admission for critical COVID-19 patients. DESIGN: This study was a retrospective analysis of a consecutive sample of patients admitted to intensive care unit between May 2020 and September 2021. Inclusion criteria encompassed the diagnosis of acute respiratory distress syndrome due to SARS-CoV-2, requiring invasive mechanical ventilation more than 48 hrs. The following predictors were evaluated: sociodemographic characteristics, comorbidities, as well as clinical and laboratory findings at intensive care unit admission. The primary outcome was the presence of pressure injuries. RESULTS: Two hundred five patients were included, mostly males (73%) with a mean age of 62 yrs. Pressure injury prevalence was 58%. On multivariable analysis, male sex, hypertension, hemoglobin, and albumin at intensive care unit admission were independently associated with pressure injuries, constituting the PRINCOVID model. The model reached an area under the receiver operating characteristic curve of 0.71, surpassing the Braden scale ( P = 0.0015). The PRINCOVID score ranges from 0 to 15, with two risk groups: "at risk"(≤7 points) and "high risk"(>7 points). CONCLUSIONS: This study proposes PRINCOVID as a multivariable model for developing pressure injuries in critical COVID-19 patients. Based on four parameters (sex, hypertension, hemoglobin, and albumin at intensive care unit admission), this model fairly predicts the development of pressure injuries. The PRINCOVID score allows patients' classification into two groups, facilitating early identification of high-risk patients.

Critical COVID-19 and neurological dysfunction - a direct comparative analysis between SARS-CoV-2 and other infectious pathogens. / COVID-19 crítico e disfunção neurológica - uma análise comparativa direta entre o SARS-CoV-2 e outros agentes infecciosos.

OBJECTIVE: To evaluate whether critical SARS-CoV-2 infection is more frequently associated with signs of corticospinal tract dysfunction and other neurological signs, symptoms, and syndromes, than other infectious pathogens. METHODS: This was a prospective cohort study with consecutive inclusion of patients admitted to intensive care units due to primary infectious acute respiratory distress syndrome requiring invasive mechanical ventilation > 48 hours. Eligible patients were randomly assigned to three investigators for clinical evaluation, which encompassed the examination of signs of corticospinal tract dysfunction. Clinical data, including other neurological complications and possible predictors, were independently obtained from clinical records. RESULTS: We consecutively included 54 patients with acute respiratory distress syndrome, 27 due to SARS-CoV-2 and 27 due to other infectious pathogens. The groups were comparable in most characteristics. COVID-19 patients presented a significantly higher risk of neurological complications (RR = 1.98; 95%CI 1.23 - 3.26). Signs of corticospinal tract dysfunction tended to be more prevalent in COVID-19 patients (RR = 1.62; 95%CI 0.72 - 3.44). CONCLUSION: Our study is the first comparative analysis between SARS-CoV-2 and other infectious pathogens, in an intensive care unit setting, assessing neurological dysfunction. We report a significantly higher risk of neurological dysfunction among COVID-19 patients. As such, we suggest systematic screening for neurological complications in severe COVID-19 patients.

OBJETIVO: Avaliar se a infecção grave pelo SARS-CoV-2 está mais comumente associada a sinais de disfunção do trato corticoespinhal e outros sinais, sintomas e síndromes neurológicas, em comparação com outros agentes infecciosos. MÉTODOS: Este foi um estudo de coorte prospectivo com inclusão consecutiva de doentes admitidos a unidades de cuidados intensivos devido a síndrome do desconforto respiratório agudo infeccioso primário, com necessidade de ventilação mecânica invasiva por > 48 horas. Os doentes incluídos foram atribuídos aleatoriamente a três investigadores para a avaliação clínica, a qual incluía a pesquisa de sinais de disfunção do trato corticoespinhal. Os dados clínicos, incluindo outras complicações neurológicas e possíveis preditores, foram obtidos independentemente a partir dos registros clínicos. RESULTADOS: Foram incluídos consecutivamente 54 doentes com síndrome do desconforto respiratório agudo, 27 devido a SARS-CoV-2 e 27 devido a outros agentes infecciosos. Os grupos eram comparáveis na maioria das características. Os doentes com COVID-19 apresentavam risco significativamente superior de complicações neurológicas (RR = 1,98; IC95% 1,23 - 3,26). Os sinais de disfunção do trato corticoespinhal tendiam a ser mais prevalentes em doentes com COVID-19 (RR = 1,62; IC95% 0,72 - 3,44). CONCLUSÃO: Este estudo foi a primeira análise comparativa visando avaliar disfunção neurológica, entre doentes com infecção SARS-CoV-2 e outros agentes infecciosos, em um contexto de unidade de cuidados intensivos. Reportamos um risco significativamente superior de disfunção neurológica em doentes com COVID-19. Como tal, sugere-se o rastreio sistemático de complicações neurológicas em doentes com COVID-19 crítico.

What is the impact of previous cerebrovascular disease on critical COVID-19 patients' mortality? A prospective cohort study.

OBJECTIVES: We aimed to evaluate the effect of previous cerebrovascular disease (CVD) on mortality rates of critically ill COVID-19 patients. MATERIALS & METHODS: A prospective cohort study was performed between May/2020 and May/2021, at a tertiary-care-center. We consecutively included adult patients admitted to intensive care units (ICU) having as primary diagnosis Acute Respiratory Distress Syndrome due to SARS-CoV-2, requiring invasive mechanical ventilation for >48 h. We considered as exposure the diagnosis of previous CVD and as main outcome the in-ICU mortality. RESULTS: The study sample included 178 patients: 74.2% were males, with a mean age of 63 ± 12.4 years-old(yo). Previous CVD was documented in 17 patients (9.6%). During the study period, the mortality rate at ICU was of 33.1% (n = 59). The proportion of mortality at ICU was higher in patients with prior CVD (58.8% vs 30.4%; p = 0.02). Also, older patients (66 ± 11.4 yo vs. 62 ± 12.7 yo, p = 0.04) and those with higher score at SAPSII at ICU admission (47.8 ± 15.4 vs. 40.7 ± 15.9; p = 0.01) had a higher ICU deathrate. Patients with previous CVD had a 2.70 (95%CI = 1.36-5.39) higher likelihood of dying compared to those who had no previous CVD. After adjustment (for gender, age, SAPSII and total length of stay), multivariate Cox analysis revealed that previous CVD remained a strong predictor for in-ICU death in critically ill COVID-19 patients (HR = 2.51; 95%CI = 1.15-5.51). CONCLUSIONS: Previous CVD was significantly associated to higher mortality in critical COVID-19 patients. We suggest that, in patients with previous CVD, prioritization of vaccination strategies should be implemented alongst with higher surveillance when infected with SARS-CoV-2.

Congenital muscular torticollis: where are we today? A retrospective analysis at a tertiary hospital.

BACKGROUND: The congenital muscular torticollis is characterized by a persistent lateral flexion of the head to the affected side and cervical rotation to the opposite side due to unilateral shortening of the sternocleidomastoid muscle. The majority of the cases resolve with conservative management, with parents/caregivers education and physical therapy.The aim of this study was to assess demographic and clinical characteristics, treatment options, and outcome, amongst infants referred to pediatric rehabilitation consultation due to congenital muscular torticollis. METHODS: Retrospective cohort study of infants diagnosed with congenital muscular torticollis between January 2012 and December 2014. Obstetric and perinatal data, clinical presentation, comorbidities, treatment, and outcome were abstracted from clinical records. RESULTS: One hundred six infants were included. There was no sex predominance and mean age at first pediatric rehabilitation consultation was 11.6 (10.4) weeks. Most women were primiparous (76.4%), dystocic labor predominated (73.6%), and pelvic fetal presentation occurred in 20.8%. At examination, 49.1% of the infants had abnormalities, beyond the tilt cervical, mainly range of motion restrictions and palpable nodule in sternocleidomastoid muscle. Among the 87 children who performed the cervical ultrasound, 29 (27.4%) had anomalies. Associated clinical conditions such as hip dysplasia were identified. The majority (71.7%) were submitted to conservative treatment, 30.2% in the Pediatric Rehabilitation Department. Most infants (97.2%) showed a complete resolution of the torticollis. CONCLUSIONS: Congenital muscular torticollis is the most common cause of torticollis in the infants. Early diagnosis, parent/caregivers education, and conservative treatment are crucial to achieving good results.

Musculoskeletal complaints in cardiac rehabilitation: Prevalence and impact on cardiovascular risk factor profile and functional and psychosocial status.

OBJECTIVE: To assess the prevalence of musculoskeletal complaints and their association with risk factor profile and functional and psychosocial status in patients on a cardiac rehabilitation program. METHODS: In this cross-sectional study of 449 patients admitted within three months of an acute coronary syndrome, patients were divided into those with (MSC+) and those without (MSC-) musculoskeletal complaints. The Hospital Anxiety and Depression Scale and the Short Form 36 Health Survey were used to assess psychosocial status and quality of life, and the International Physical Activity Questionnaire for physical activity. Functional capacity was estimated from exercise testing. RESULTS: Musculoskeletal pain was present in 119 patients (27%), mainly in the lower limbs (56%). MSC+ were older (mean 56.5±9.9 vs. 53.2±9.5 years; p<0.001) and more frequently women (20.2% vs. 9.1%; p<0.001). MSC+ had a higher prevalence of dyslipidemia (68.6% vs. 51.2%; p<0.001), hypertension (51.7% vs. 35.5%; p<0.001), obesity (29.4% vs. 17.9%; p<0.001) and metabolic syndrome (44.5% vs. 31.5%; p<0.001). MSC+ showed higher body mass index and waist circumference, and lower physical activity levels (p<0.05), as well as lower functional capacity (8.6±2.2 vs. 9.6±2.1 MET; p<0.05), higher scores for depression (6 [3-9] vs. 3 [1-7]; p<0.05) and anxiety (7 [3-10] vs. 5 [2-8]; p<0.05), and lower scores for physical (44.1±8.7 vs. 47.6±7.6; p<0.05) and mental (39.2±13.0 vs. 44.0±13.0; p<0.05) quality of life. CONCLUSIONS: Musculoskeletal complaints are common in cardiac rehabilitation and predict lower levels of physical activity, worse cardiovascular risk factor profile, and poorer functional capacity and psychosocial status, irrespective of age and gender.
