Background and Objectives: Hospitalization by Covid‐19 can cause persistent functional consequences after hospital discharge due to direct and indirect effects of SARS‐COV‐2 in several organs and systems of the body added to post‐intensive care syndrome and prolonged bed rest. These impacts can lead to dependency in activities of daily living, mainly in older people due to aging process and functional decline. This study aimed to compare the effects of hospitalization by Covid‐19 on functional capacity of adults and older people and to identify its associated factors. Methods: Cross‐sectional observational study of 159 survivors of hospitalization by Covid‐19 after 1 month from discharge at Hospital das Clínicas of the University of São Paulo, divided into groups: adults (aged < 60 years) and older people (aged ≥ 60 years). Those who did not accept to participate, without availability or without ability to understand the questionnaires were excluded. Functional capacity was assessed by the Barthel Index and patients were classified according to their scores. Data analysis was performed in JASP Statistics program and the sample was compared between the age groups. Wilcoxon test was applied to compare before and after periods, Mann–Whitney test was used for between groups comparison. We adopted alpha = 0.05. Results: The total Barthel Index median score was lower 1 month after hospital discharge than in the pre‐Covid‐19 period. Older people had worse functional status than adults before and also showed greater impairment after hospital discharge. Both groups showed lower Barthel Index classification than before, and older people presented more functional dependence than adults in both periods. Age, sarcopenia and frailty were associated factors. Discussion: Hospitalization by Covid‐19 impacts functional capacity after 1 month from discharge, especially in older people. Age, sarcopenia and frailty are associated factors. These results suggest need for care and rehabilitation of Covid‐19 survivors. [ABSTRACT FROM AUTHOR]

Heart disease (HD) can stress the alveolar blood-gas barrier, resulting in parenchymal inflammation and remodeling. Patients with HD may therefore display any of the symptoms commonly attributed to primary pulmonary disease, although tissue documentation of corresponding changes through surgical lung biopsy (SLB) is rarely done. Intent on exploring the basis of HD-related alveolar-capillary barrier dysfunction, a retrospective analysis of SLB histopathology was conducted in patients with clinically diagnosed HD, diffuse pulmonary infiltrates, and no evidence of primary pulmonary disease. Patients eligible for the study had a clinical diagnosis of heart disease, acute or chronic, and presented with diffuse infiltrates on chest X-ray. All qualified subjects (N = 23) who underwent diagnostic SLB between January 1982 and December 2005 were subsequently examined. Specific biopsy parameters investigated included demonstrable edema, siderophage influx, hemorrhage, venous and lymphatic ectasia, vascular sclerosis, capillary congestion, and fibroblast proliferation. Based on observed alveolar-capillary barrier (ACB) alterations, three main morphologic groups emerged: one group (6 patients) with alveolar edema; a second group (11 patients) characterized by pulmonary congestion; and a final group (6 patients) showing microscopic foci of acute ACB lung injury. Alveolar-capillary stress due to acute high-pressure or volume overload often manifests as diffuse pulmonary infiltrates with variable but generally predictable histopathology. In patients with biopsy-proven alveolar edema, pulmonary congestion, or acute microscopic lung injury, the clinician must be alert for the possibility of primary heart disease, particularly if the patient is elderly or when a history of myocardial, valvular, or coronary vascular disease exists. Keywords Heart disease * Pulmonary histological patterns * Pulmonary edema * Pulmonary congestion * Surgical lung biopsy * Microfoci of acute lung injury, Introduction Cardiac dysfunction typically involves one of the following mechanisms: blood loss, irregular heartbeat, obstructed flow, regurgitating flow, contractile dysfunction (systolic failure), or inadequate filling (diastolic failure) (1) .

Background: Capacity strain negatively impacts patient outcome, and the effects of patient surge are a continuous threat during the COVID-19 pandemic. Evaluating changes in mortality over time enables evidence-based resource planning, thus improving patient outcome. Our aim was to describe baseline risk factors associated with mortality among COVID-19 hospitalized patients and to compare mortality rates over time. Methods: We conducted a retrospective cohort study in the largest referral hospital for COVID-19 patients in Sao Paulo, Brazil. We investigated risk factors associated with mortality during hospitalization. Independent variables included age group, sex, the Charlson Comorbidity Index, admission period according to the stage of the first wave of the epidemic (early, peak, and late), and intubation. Results: We included 2949 consecutive COVID-19 patients. 1895 of them were admitted to the ICU, and 1473 required mechanical ventilation. Median length of stay in the ICU was 10 (IQR 5–17) days. Overall mortality rate was 35%, and the adjusted odds ratios for mortality increased with age, male sex, higher Charlson Comorbidity index, need for mechanical ventilation, and being admitted to the hospital during the wave peak of the epidemic. Being admitted to the hospital during the wave peak was associated with a 33% higher risk of mortality. Conclusions: In-hospital mortality was independently affected by the epidemic period. The recognition of modifiable operational variables associated with patient outcome highlights the importance of a preparedness plan and institutional protocols that include evidence-based practices and allocation of resources.

Background: The decision to intubate COVID-19 patients receiving non-invasive respiratory support is challenging, requiring a fine balance between early intubation and risks of invasive mechanical ventilation versus the adverse effects of delaying intubation. This present study analyzes the association between intubation day and mortality in COVID-19 patients. Methods: We performed a unicentric retrospective cohort study considering all COVID-19 patients consecutively admitted between March 2020 and August 2020 requiring invasive mechanical ventilation. The primary outcome was all-cause mortality within 28 days after intubation, and a Cox model was used to evaluate the effect of time from onset of symptoms to intubation in mortality. Results: A total of 592 (20%) patients of 3020 admitted with COVID-19 were intubated during study period, and 310 patients who were intubated deceased 28 days after intubation. Each additional day between the onset of symptoms and intubation was significantly associated with higher in-hospital death (adjusted hazard ratio, 1.018; 95% CI, 1.005–1.03). Conclusion: Among patients infected with SARS-CoV-2 who were intubated and mechanically ventilated, delaying intubation in the course of symptoms may be associated with higher mortality. Trial registration: The study protocol was approved by the local Ethics Committee (opinion number 3.990.817; CAAE: 30417520.0.0000.0068). [ABSTRACT FROM AUTHOR]
