Objective: To identify the indications for physiotherapy and to evaluate physiotherapy practices in patients with COVID-19 admitted to the ICU (on mechanical ventilation) or to the ward (spontaneously breathing). Methods: An online, 50-item survey was completed by physiotherapists who had been treating hospitalized patients with COVID-19 in Brazil. Results: Of the 644 physiotherapists who initiated the survey, 488 (76%) completed it. The main reasons for indications for physiotherapy in both settings reported as "very frequently" and "frequently" both in the ICU and the ward by most respondents were oxygenation improvement (> 95%) and prevention of general complications (> 83%). Physical deconditioning was considered an infrequent indication. When compared with mobilization strategies, the use of respiratory interventions showed great variability in both work settings, and techniques considered effective were underutilized. The most frequently used respiratory techniques in the ICU were positioning (86%), alveolar recruitment (73%), and hard/brief expiratory rib cage compression (46%), whereas those in the ward were active prone positioning (90%), breathing exercises (88%), and directed/assisted cough (75%). The mobilization interventions reported by more than 75% of the respondents were sitting on the edge of the bed, active and resistive range of motion exercises, standing, ambulation, and stepping in place. Conclusions: The least common reason for indications for physiotherapy was avoidance of deconditioning, whereas oxygenation improvement was the most frequent one. Great variability in respiratory interventions was observed when compared with mobilization therapies, and there is a clear need to standardize respiratory physiotherapy treatment for hospitalized patients with COVID-19.

Objective: The present study aimed to assess the functional status of children diagnosed with COVID-19 at the time of hospitalization and the associations with clinical features. Methods: This prospective cohort study was carried out with children diagnosed with COVID-19 admitted to a tertiary hospital. The patients' functioning was assessed using the pediatric Functional Status Scale (FSS). Results: A total of 62 children with a median age of 3 years old were included in the study, and 70% had some comorbidity prior to the diagnosis of COVID-19. The median length of stay was nine days, during which period five patients died. The FSS assessment of the sample showed that approximately 55% had some functional alteration. The group of patients with the highest FSS scores presented a lengthier hospital stay (p = 0.016), required more oxygen therapy (p < 0.001), mechanical ventilation (p = 0.001), and intensive care unit admissions (p = 0.019), and had more cardiac (p = 0.007), neurological (p = 0.003), and respiratory (p = 0.013) comorbidities. In the multivariate analysis, there was an association between the dependent variable length of stay and the total FSS score (b = 0.349, p = 0.004) and the presence of comorbidities (b = 0.357, p = 0.004). Conclusions: We observed that more than half of the children hospitalized due to COVID-19 had some level of functional change. Greater alterations in functional status were associated with the presence of previous comorbidities, a greater need for ventilatory support, and longer hospital stays.

Objective: To describe the prevalence of anemia and of its types in hospitalized patients with pulmonary tuberculosis. Methods: This was a descriptive, longitudinal study involving pulmonary tuberculosis inpatients at one of two tuberculosis referral hospitals in the city of Rio de Janeiro, Brazil. We evaluated body mass index (BMI), triceps skinfold thickness (TST), arm muscle area (AMA), ESR, mean corpuscular volume, and red blood cell distribution width (RDW), as well as the levels of C-reactive protein, hemoglobin, transferrin, and ferritin. Results: We included 166 patients, 126 (75.9%) of whom were male. The mean age was 39.0  10.7 years. Not all data were available for all patients: 18.7% were HIV positive; 64.7% were alcoholic; the prevalences of anemia of chronic disease and iron deficiency anemia were, respectively, 75.9% and 2.4%; and 68.7% had low body weight (mean BMI = 18.21 kg/m2). On the basis of TST and AMA, 126 (78.7%) of 160 patients and 138 (87.9%) of 157 patients, respectively, were considered malnourished. Anemia was found to be associated with the following: male gender (p = 0.03); low weight (p = 0.0004); low mean corpuscular volume (p = 0.03);high RDW (p = 0; 0003); high ferritin (p = 0.0005); and high ESR (p = 0.004). We also found significant differences between anemic and non-anemic patients in terms of BMI (p = 0.04), DCT (p = 0.003), and ESR (p < 0.001). Conclusions: In this sample, high proportions of pulmonary tuberculosis patients were classified as underweight and malnourished, and there was a high prevalence of anemia of chronic disease. In addition, anemia was associated with high ESR and malnutrition.

Objective: Because SARS-CoV-2 infection can severely affect the lungs and persistent functional changes can occur after severe disease, we aimed to determine lung function parameters of COVID-19 patients at 45 days after hospital discharge and compare changes according to the severity of the disease. Methods: This was a prospective descriptive analytical multicenter study. The participants were allocated into three groups: ward admission (WA) group; ICU admission not on mechanical ventilation (ICU/MV-) group; and ICU admission on MV (ICU/MV+) group. Lung volumes, DLco, MIP, MEP, and six-minute walk distance (6MWD) were measured 45 days after discharge. Results: The sample comprised 242 patients (mean age = 59.4 ± 14.8 years; 52.1% of males), and 232 (96%) had altered lung function. In the total cohort, restrictive disorder was observed in 96%, as well as reductions in DLco (in 21.2% of the patients), FEV1/FVC (in 39.7%), and PEmax (in 95.8%), with no differences between the groups. Comparing the groups, the ICU/MV+ group had reduced DLco in 50% of the patients (p < 0.001) and a lower mean 6MWD % of the predicted value (p = 0.013). Oxygen desaturation in the six-minute walk test was observed in 32.3% of the cohort and was less frequent in the IE group. Conclusions: This is the first South American study involving severe COVID-19 survivors whose lung function was assessed 45 days after hospital discharge. Changes were frequent, especially in those on MV, which highlights the importance of lung function evaluation after severe COVID-19.

Objective: Currently, little is known about the long-term outcomes of COVID-19 in the pediatric population. The aim of this study was to investigate the long-term clinical outcomes of pediatric patients hospitalized with COVID-19. Methods: This was a prospective cohort study involving unvaccinated children and adolescents admitted to a tertiary hospital in southern Brazil with a COVID-19 diagnosis. Data were collected from electronic medical records for one year after the diagnosis. Results: A total of 66 children were included: the median age was 2.9 years; 63.6% were male; and 48.5% were under 2 years of age. Over 70% had at least one comorbidity prior to the COVID-19 diagnosis. During the one-year follow-up period, 59.1% of the children revisited the emergency department, 50% required readmission, and 15.2% died. Younger children with longer hospital stays were found to be at greater risk of readmission. Having cancer and impaired functionality were found to increase the risk of death within one year. Conclusions: Our findings indicate that most children hospitalized with COVID-19 have comorbidities. Younger age at admission and a longer hospital stay seem to be risk factors for readmission. In addition, the presence of cancer and impaired functionality are apparently associated with the poor outcome of death within the first year after the diagnosis of COVID-19.

Objective: Although COPD is a prevalent disease, it is undertreated, and there are no available data regarding previous treatment of COPD in Brazil. This study aimed to determine the appropriateness of maintenance treatment in COPD patients prior to their hospitalization and to identify variables associated with inappropriate treatment. Methods: This was an observational, cross-sectional, analytical study involving 50 inpatients with COPD at two hospitals in the city of Florianópolis, Brazil. The patients completed a questionnaire on parameters related to the maintenance treatment of COPD. Non-pharmacological management and pharmacological treatment were assessed based on the recommendations made by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) in 2011 and by the Brazilian National Ministry of Health in the chronic respiratory diseases section of its Caderno de Atenção Básica (CAB, Primary Care Guidebook). Results: In most of the patients, the COPD was classified as being severe or very severe. Regarding non-pharmacological management, 33% of the patients were smokers, only 32% had been advised to receive the flu vaccine, 28% had received pneumococcal vaccine, and only 6.5% of the patients in the B, C, and D categories received pulmonary rehabilitation. Regarding GOLD and CAB recommendations, pharmacological treatment was inappropriate in 50% and 74% of the patients, respectively. Based on GOLD recommendations, 38% were undertreated. A low level of education, low income, not receiving oxygen therapy, and not receiving the flu vaccine were associated with inappropriate treatment. Conclusions: The application of various non-pharmacological management recommendations was unsatisfactory. Regarding the GOLD recommendations, the high rate of inappropriate maintenance treatment was mainly due to undertreatment. In Brazil, even in severe COPD cases, optimizing treatment to achieve greater benefits continues to be a challenge.

Objective: To assess the routine use of barium swallow study in patients with chronic cough. Methods: Between October of 2011 and March of 2012, 95 consecutive patients submitted to chest X-ray due to chronic cough (duration > 8 weeks) were included in the study. For study purposes, additional images were obtained immediately after the oral administration of 5 mL of a 5% barium sulfate suspension. Two radiologists systematically evaluated all of the images in order to identify any pathological changes. Fisher's exact test and the chi-square test for categorical data were used in the comparisons. Results: The images taken immediately after barium swallow revealed significant pathological conditions that were potentially related to chronic cough in 12 (12.6%) of the 95 patients. These conditions, which included diaphragmatic hiatal hernia, esophageal neoplasm, achalasia, esophageal diverticulum, and abnormal esophageal dilatation, were not detected on the images taken without contrast. After appropriate treatment, the symptoms disappeared in 11 (91.6%) of the patients, whereas the treatment was ineffective in 1 (8.4%). We observed no complications related to barium swallow, such as contrast aspiration. Conclusions: Barium swallow improved the detection of significant radiographic findings related to chronic cough in 11.5% of patients. These initial findings suggest that the routine use of barium swallow can significantly increase the sensitivity of chest X-rays in the detection of chronic cough-related etiologies.

Objective: To describe the demographic and clinical characteristics of patients with tuberculosis hospitalized in the Nestor Goulart Reis Hospital, located in the city of Américo Brasiliense, Brazil. Methods: Epidemiological investigation by means of an observational, retrospective, descriptive study based on the medical charts of patients diagnosed with tuberculosis and hospitalized between 1994 and 2004. Results: There were 1787 patients diagnosed with tuberculosis during the period evaluated. Of those, 117 (7%) were females, 1670 (93%) were males; 1215 (68%) were single, separated or widowed. Most of the patients (74%) had not completed middle school, and most (63%) were between 30 and 50 years of age. In addition, 61% suffered from alcoholism. The most common occupation was farm worker (25% of the patients), and 70% of the patients were unemployed. The most common clinical form of the disease was the pulmonary form (in 92%). The rate of medical discharge was 60%. The treatment regimen differed from the standard (rifampin, isoniazid and pyrazinamide) in 34% of the cases. Conclusions: The profile of the patients with tuberculosis hospitalized in the hospital studied showed that they had special requirements: they were unable to take care of themselves (social cases) and required alternative treatment regimens, which justified their hospitalization. This hospital played an important social role in the treatment and guidance of these patients.

Objective: To describe the rates of adherence to the 2019 European Society of Cardiology guideline recommendations on the setting of care for patients with acute pulmonary embolism (PE) of varying severity. Methods: This was a retrospective cohort study of PE patients treated in a referral hospital in Colombia between 2019 and 2022. Results: We analyzed 506 patients with acute PE (median age, 67 years). Of those, 58% were women, and 33% had a history of cancer. In-hospital mortality was 9.2%, and 30-day mortality was 17.9%. Of the total of patients, 8.3% were classified as low-risk patients, 77.6% were classified as intermediate-low-risk patients, 11.2% were classified as intermediate-high-risk patients, and 2.7% were classified as high-risk patients. Of the total of low-risk patients, 9.5% were discharged early in accordance with the guideline recommendations. Of the total of intermediate-high-risk patients, 43.8% were treated in the general ward instead of being transferred to the ICU for monitoring. Of the total of high-risk patients, 92.8% were treated in the ICU. No cancer patients were discharged early. Conclusions: These results suggest that clinical practice guideline recommendations regarding the setting of care for patients with acute PE are not being followed. This is particularly true for low-risk PE patients who may be candidates for early discharge. Further studies are needed to investigate the reasons why low-risk patients are not being discharged early.

Objective: Studies assessing the characteristics and management of patients hospitalized with asthma have been limited to a small number of facilities and have evaluated short time periods. The present study evaluated long-term changes among hospitalized asthma patients at a large number of facilities. Methods: This was a retrospective, hospital-based observational case series, designated the Study of Severe Asthma in Latin America and Spain, which was conducted in Spain and in eight Latin-American countries. We reviewed the hospital records of 3,038 patients (age range, 15-69 years) hospitalized with acute severe asthma at one of nineteen tertiary-care hospitals in 1994, 1999 and 2004. Results: Over time, the use of inhaled corticosteroids and long-acting β2 agonists increased significantly, whereas the use of theophylline as a controller medication decreased. The utilization of pulmonary function tests also increased. There was a significant reduction in the mean hospital stay (8.5 days, 7.4 days and 7.1 days in 1994, 1999 and 2004, respectively, p = 0.0001) and a significant increase in the mean of the lowest arterial pH at hospital admission. In contrast, there was a significant decrease in the proportion of cases in which PEF was determined in the emergency room (48.6% in 1994 vs. 43.5% in 2004, p = 0.0001). We found the quality of asthma management and care to be generally better in Spain than in Latin America. Conclusions: Although there have been certain improvements in the management of asthma between severe exacerbations and during hospitalization, asthma management remains suboptimal in Spain and, especially, in Latin America.

Objective: To determine the epidemiological profile of inpatients at a TB referral hospital. Methods: This was a descriptive, retrospective study of the medical charts of patients with TB hospitalized at the Hospital Estadual Santa Maria (HESM), in the city of Rio de Janeiro, Brazil, between January of 2002 and December of 2003. Data were collected using a standardized form. Results: Of the 451 patients included in the study, 313 (69.4%) had been referred to the HESM from health care clinics, and 302 (67.0%) were male. Most of the patients were in the 30-59  year age bracket, 443 (98.2%) lived in the greater metropolitan region of Rio de Janeiro, and 298 (66.1%) lived in the city of Rio de Janeiro itself. The most common reason for hospitalization was poor health status (in 237, 52.5%). The most common comorbidity was AIDS (in 137, 30.4%). The most common signs and symptoms at admission were weight loss, fever and productive cough. Sputum smear microscopy was positive in 122 (71.0%) of the patients presenting with productive cough at admission. Of the 212 patients being retreated, 156 (73.6%) reported noncompliance with previous treatment. Regarding the outcome, 273 (65.8%) of the patients were referred to municipal health care centers, 83 (18.4%) died, 44 (9.8%) were cured, and 27 (6%) were discharged against medical advice. Conclusions: Providing hospitals specializing in TB is relevant for TB control, especially in metropolitan regions. In addition to taking biosafety measures, these hospitals must be prepared to treat patients with TB-related comorbidities and social problems. This study has resulted in improvements at the HESM.

Objective: To evaluate the agreement between the criteria used for hospitalization of patients with community-acquired pneumonia (CAP) and those of the Brazilian Thoracic Association guidelines, and to evaluate the association of that agreement with 30-day mortality. Secondarily, to evaluate the agreement between the treatment given and that recommended in the guidelines with length of hospital stay, microbiological profile, 12-month mortality, complications, ICU admission, mechanical ventilation, and 30-day mortality. Methods: This was a retrospective study involving adult patients hospitalized between 2005 and 2007 at the Federal University of Minas Gerais Hospital das Clínicas, located in Belo Horizonte, Brazil. Medical charts and chest X-rays were reviewed. Results: Among the 112 patients included in the study, admission and treatment criteria were in accordance with the guidelines in 82 (73.2%) and 66 (58.9%), respectively. The 30-day and 12-month mortality rates were 12.3% and 19.4%, respectively. The 30-day mortality rate was lower for patients in whom the CRB-65 (mental Confusion, Respiratory rate, Blood pressure, and age ≥ 65 years) score was 1-2 and the antibiotic therapy was in accordance with the guidelines (p = 0.01). Cerebrovascular disease and appropriate antibiotic therapy showed independent associations with 30-day mortality. There was a trend toward an association between guideline-concordant antibiotic therapy and shorter hospital stay. Conclusions: In the population studied, admission and treatment criteria that were in accordance with the guidelines were associated with favorable outcomes in hospitalized patients with CAP. Cerebrovascular disease, as a risk factor, and guideline-concordant antibiotic therapy, as a protective factor, were associated with 30-day mortality.

Objective: To assess differences in the sputum microbiota of community-acquired pneumonia (CAP) patients with either COPD or asthma, specifically focusing on a patient population in Turkey. Methods: This retrospective study included hospitalized patients > 18 years of age with a diagnosis of pneumonia between January of 2021 and January of 2023. Participants were recruited from two hospitals, and three patient groups were considered: CAP patients with asthma, CAP patients with COPD, and CAP patients without COPD or asthma. Results: A total of 246 patients with CAP were included in the study, 184 (74.8%) and 62 (25.2%) being males and females, with a mean age of 66 ± 14 years. Among the participants, 52.9% had COPD, 14.2% had asthma, and 32.9% had CAP but no COPD or asthma. Upon analysis of sputum cultures, positive sputum culture growth was observed in 52.9% of patients. The most commonly isolated microorganisms were Pseudomonas aeruginosa (n = 40), Acinetobacter baumannii (n = 20), Klebsiella pneumoniae (n = 16), and Moraxella catarrhalis (n = 8). CAP patients with COPD were more likely to have a positive sputum culture (p = 0.038), a history of antibiotic use within the past three months (p = 0.03), utilization of long-term home oxygen therapy (p < 0.001), and use of noninvasive ventilation (p = 0.001) when compared with the other patient groups. Additionally, CAP patients with COPD had a higher CURB-65 score when compared with CAP patients with asthma (p = 0.004). Conclusions: This study demonstrates that CAP patients with COPD tend to have more severe presentations, while CAP patients with asthma show varied microbial profiles, underscoring the need for patient-specific management strategies in CAP.

Objective: To evaluate, for the first time, the characteristics of patients with acute asthma who died during hospitalization in Spain and Latin America, as well as to evaluate factors associated with asthma mortality. Methods: A retrospective review of hospital records of 3,038 patients with asthma (aged 15-69 years) admitted to nineteen tertiary care hospitals in Spain and in eight Latin-American countries in 1994, 1999, and 2004. Results: There were 25 deaths (0.8% of all hospitalized patients) during the three years studied. Although there was a tendency towards a reduction in in-hospital mortality (from 0.97% in 1994 to 0.69% in 2004), there were no significant differences in terms of year or geographic area. Intensive care unit admissions and cases of out of hospital cardiopulmonary arrest increased the mortality rates to 8.3% and 24.7%, respectively. The multivariate analysis showed that gender (female; OR = 25.5; 95% CI: 2.6-246.8), out of hospital cardiopulmonary arrest (OR = 22.5; 95% CI: 4.4-114.7), and arterial pH < 7.3 during hospitalization (OR = 1.0; 95% CI: 1.1-3.4) were strongly associated with asthma mortality. Conclusions: Our study on mortality in patients hospitalized for acute severe asthma showed that deaths occurred almost exclusively in female patients and in patients who suffered out of hospital cardiopulmonary arrest, confirming previous findings from studies conducted in developed countries.

Objectives: To verify the prevalence of tuberculosis (TB)/HIV co-infection and the ability of the clinical history to detect the HIV infection in TB inpatients. Setting: Eduardo de Menezes Hospital, reference for both TB and AIDS. Patients and methods: All patients admitted with TB in a pneumology ward were evaluated prospectively from 1/1/1997 to 1/31/1998. The clinical history was directed to the presence of risk factors for AIDS or TB, previous treatments or abandoned treatments for TB, and TB clinical forms. Patients with AIDS defining illnesses, except for TB, and with previous anti-HIV tests were excluded. All patients had an ELISA anti-HIV serology, and when positive, a Western-Blot test was performed to confirm the previous result. X-square test and Fisher test were used for statistical analysis. Results: Sixty-five patients were divided into group I (positive serology for HIV, n = 6) and group II (negative serology for HIV, n = 59). There were no statistical differences between the groups comparing the risk factors for AIDS and TB, previous treatments or abandoned treatments for TB, or TB clinical forms. Conclusions: The high prevalence of TB/HIV co-infection (9.2%) reinforces that: 1) the clinical history was not able to detect a significant number of patients with TB/HIV co-infection and that: 2) anti-HIV serology should be performed in all patients with active TB forms.

Objective: To determine the frequency of smoking among hospitalized patients in a general hospital, and to evaluate their profile. Methods: A random representative sample of 111 patients, classified as nonsmokers, former smokers or smokers, was evaluated. The smokers were submitted to the Fagerström test and measurement of expired carbon monoxide. Expired carbon monoxide higher than 6 ppm was considered a significant indicator of recent smoking. Results: Of the 111 patients in the sample, 60 (54%) were female. The mean age was 70 years. Of the 111 patients, 56 (51%) had never smoked, 36 (32%) were former smokers, and 19 (17%) were smokers. All of the smokers were male. The smokers were younger (58 ± 17 years) than the nonsmokers (68 ± 12 years) and the former smokers (73 ± 14 years)-ANOVA: F = 6.57 (p = 0.002). Among the smokers, the mean tobacco intake was 43 pack-years and the mean Fagerström score was 5.0. Of the 19 smokers, 11 (58%) had respiratory symptoms and 3 had withdrawal symptoms. The mean expired carbon monoxide in the smokers was 5.0 ppm. Expired carbon monoxide levels were higher than 6 ppm in 8 (42%) of the smokers. There was a higher prevalence of smokers in some wards: 70% of all smokers were hospitalized on only five wards. Conclusions: In a large tertiary hospital, 17% of the hospitalized patients were smokers, and 7% had smoked within the last 8 h. The smokers were younger men, hospitalized on specific wards.

Objective: The gait speed test (GST) is a physical test that can predict falls and aid in the diagnosis of sarcopenia in the elderly. However, to our knowledge, there have been no studies evaluating its reproducibility in hospitalized elderly patients. The objective of this study was to evaluate the safety and reproducibility of the six-meter GST (6GST) in hospitalized elderly patients. Methods: This repeated measures study involved hospitalized elderly patients (≥ 60 years of age) who underwent the 6GST by the fifth day of hospitalization, were able to walk without assistance, and presented no signs of dyspnea or pain that would prevent them from performing the test. The 6GST was performed three times in sequence, with a rest period between each test, in a level corridor. Gait speed was measured in meters/second. Reproducibility was assessed by comparing the means, intraclass correlation coefficients (ICCs) and Bland-Altman plots. Results: We evaluated 110 elderly patients in a total of 330 tests. All participants completed all of the tests. The comparisons between the speeds obtained during the three tests showed high ICCs and a low mean bias (Bland-Altman plots). The correlation and accuracy were greatest when the mean maximum speed was compared with that obtained in the third test (1.26 ± 0.44 m/s vs. 1.22 ± 0.44 m/s; ICC = 0.99; p = 0.001; mean bias = 0.04; and limits of agreement = −0.27 to 0.15). Conclusions: The 6GST was proven to be safe and to have good reproducibility in this sample of hospitalized elderly patients. The third measurement seems to correspond to the maximum speed, since the first two measurements underestimated the actual performance.
