Introduction: one of the most prominent extra-pulmonary manifestations in patients with chronic respiratory disease are changes in body weight and composition. However, the frequency and functional consequences of low appendicular lean mass (ALM) or sarcopenic obesity (SO) in patients with asthma is largely unknown. Therefore, the aims of the current study were to assess the frequency and functional consequences of low appendicular lean mass index (ALMI) and SO in patients with asthma. Methods: a retrospectively analyzed cross-sectional study was conducted in 687 patients with asthma (60% female, 58 +/- 13 years, FEV1 76 +/- 25%pred) referred for comprehensive pulmonary rehabilitation (PR). Body composition, pulmonary function, exercise capacity, quadriceps muscle function, and quality of life were assessed. Patients were classified as presenting low ALMI according to the 10th percentiles of age-sex-body mass index (BMI)-specific reference values and as having SO according to the diagnostic procedure proposed by the 2022 ESPEN/EASO consensus. In addition, clinical outcomes between patients with normal and low ALMI or with and without SO were compared.Results: the frequency of patients classified as low ALMI was 19%, whereas 45% of the patients were obese. Among the obese patients, 29% had SO. In patients with normal weight, those with low ALMI were younger and had worse pulmonary function, exercise capacity and quadriceps muscle function than those with normal ALMI (all p

SUMMARY OBJECTIVE: Our study aimed to evaluate the correlation of cardiac troponin T levels with comorbidities and in-hospital outcomes in patients with coronavirus disease-2019 in Brazil. METHODS: Data from a cohort of 3,596 patients who were admitted with suspected coronavirus disease-2019 in a Brazilian tertiary center, between March and August 2020, were reviewed. A total of 2,441 (68%) patients had cardiac troponin T determined in the first 72 h of admission and were stratified into two groups: elevated cardiac troponin T (cardiac troponin T >0.014 ng/mL) and normal cardiac troponin T. Associations between troponin, comorbidities, biomarkers, and outcomes were assessed. Regression models were built to assess the association of several variables with in-hospital mortality. RESULTS: A total of 2,441 patients were embraced, of which 924 (38%) had normal cardiac troponin T and 1,517 (62%) had elevated cardiac troponin T. Patients with elevated cardiac troponin T were older and had more comorbidities, such as cardiovascular disease, hypertension, diabetes, arrhythmia, renal dysfunction, liver disease, stroke, cancer, and dementia. Patients with abnormal cardiac troponin T also had more altered laboratory parameters on admission (i.e., leukocytes, C-reactive protein, D-dimer, and B-type natriuretic peptide), as well as more need for intensive care unit, vasoactive drugs, mechanical ventilation, dialysis, and blood transfusion. All-cause mortality was markedly higher among patients with increased cardiac troponin T (42 vs. 16%, P

Objectives:To identify the characteristics of individuals with Chronic Obstructive Pulmonary Disease (COPD) that exacerbate or not during a exercise training (ET) program, and check if any these groups are less likely to the benefits of ET. Methods:Individuals with COPD were evaluated for lung function, respiratory muscle strength, body composition, 6-minute walk test (6MWT), peripheral muscle strength, quality of life, functional status, dyspnea sensation in daily life (Medical Research Council [MRC] scale), anxiety and depression. All individuals performed a high-intensity exercise training (ET) program with aerobic exercises and strength training (three times/week, 12 weeks). For analysis, the individuals were separated into two groups (Group that Exacerbated [GE] and Group that did Not Exacerbate [GNE], and compared as to their characteristics. Results: 44 individuals completed the ET (26 in the GNE [FEV1 46±16%predicted] and 18 in the GE [FEV1 42±18 %predicted]). In pre-training, GE individuals were younger, more anxious and with worse forced vital capacity than GNE. After the ET, only the GE showed significant improvement in dyspnea (pre vs post-training: MRC 4 [3–4] vs 3 [2–4]; P=0.03) and only the GNE in the 6MWT (478 [424-519] vs 516 [467–558]; P

Introduction: Interstitial lung diseases (ILD) present similar clinical characteristics such as dyspnea and exercise intolerance. These characteristics are accentuated during physical exertion, although this has not yet been investigated in depth in this population. Aims: To compare the subjective sensation of dyspnea and fatigue by workload during exercise testing (ET) between patients with ILD and healthy subjects. Methods: The individuals performed the CPET on a cycle ergometer with an incremental protocol. At each stage of the test, the sensation of exertion was collected using the Borg scale of dyspnea (D) and fatigue (F). The slopes of the D and F curves by stage in the test were compared using linear regression using the Zar method (F test). Results: 37 patients with ILD and 29 controls were studied. The ILD group had a lower maximum load (60[40-80] vs healthy 120[100-160]; (P

There are several emerging threads from the field of Green Criminology (GC) that provide for a dialogue with, and extension of, our collective analysis of environmental harm, of escalating social conflict on the frontiers of resource extraction and cultivation, and the indivisibility of ecological damage from corporeal rupture for the subjects of this study. The regular transgression of regional, national and international legal instruments supposedly protecting environments and human rights involves the often opaque and complex organisation of, and inter-relation between, local, corporate and state actors whose activities constitute- but are rarely prosecuted as- criminal behaviour. GC has shifted a focus beyond the immediacy of environmental crime to consider the broader motivations for and outcomes of environmental disruption and this invites a closer interrogation of the social relations and tensions that underpin a seemingly uncontrollable territorial advance of environmental degradation, and an intensification in conflict in culturally and bio-diverse regions. This paper builds upon the class oriented and southern perspectives on green crime to contextualise and analyse resistance by riverine, quilombolo , indigenous and agrarian communities in the globally important Amazon and Cerrado biomes of Brazil. These have been the target of violent land invasions and massive scale hydro energetic, mining and agribusiness projects, yet the communities have organised in ways that merit attention due to the different spaces and scales of contestation with relative success.
