title: Cardiopulmonary Exercise Testing in Post-COVID-19 Patients: Where Does Exercise Intolerance Come From?

description: Abstract Background Post-COVID-19 exercise intolerance is poorly understood. Cardiopulmonary exercise testing (CPET) can identify the underlying exercise limitations. Objectives To evaluate the source and magnitude of exercise intolerance in post-COVID-19 subjects. Methods Cohort study assessing subjects with different COVID-19 illness severities and a control group selected by propensity score matching. In a selected sample with CPET prior to viral infection, before and after comparisons were performed. Level of significance was 5% in the entire analysis. Results One hundred forty-four subjects with COVID-19 were assessed (median age: 43.0 years, 57% male), with different illness severities (60% mild, 21% moderate, 19% severe). CPET was performed 11.5 (7.0, 21.2) weeks after disease onset, with exercise limitations being attributed to the peripheral muscle (92%), and the pulmonary (6%), and cardiovascular (2%) systems. Lower median percent-predicted peak oxygen uptake was observed in the severe subgroup (72.2%) as compared to the controls (91.6%). Oxygen uptake differed among illness severities and controls at peak and ventilatory thresholds. Conversely, ventilatory equivalents, oxygen uptake efficiency slope, and peak oxygen pulse were similar. Subgroup analysis of 42 subjects with prior CPET revealed significant reduction in only peak treadmill speed in the mild subgroup and in oxygen uptake at peak and ventilatory thresholds in the moderate/severe subgroup. By contrast, ventilatory equivalents, oxygen uptake efficiency slope, and peak oxygen pulse did not change significantly. Conclusions Peripheral muscle fatigue was the most common exercise limitation etiology in post-COVID-19 patients regardless of the illness severity. Data suggest that treatment should emphasize comprehensive rehabilitation programs, including aerobic and muscle strengthening components.

title: Secondary Pharmacological Prevention of Coronary Artery Disease among Patients Submitted to Clinical Management, Percutaneous Coronary Intervention, or Coronary Artery Bypass Graft Surgery

description: Abstract Background Secondary prevention is recommended for patients with evidence of coronary artery disease (CAD) regardless of the indication for treatment by coronary artery bypass graft surgery (CABG) or percutaneous coronary intervention (PCI). Objectives This study evaluated whether clinical treatment, PCI or CABG had an influence on adherence to the pharmacological secondary prevention in patients with stable CAD. Methods This cohort included patients aged ≥40 years with stable CAD confirmed by coronary angiography. The decision for medical treatment alone, or additionally with PCI or CABG, was made by the attending physicians. Adherence to the prescribed drugs recommended by the guidelines for secondary prevention (optimal pharmacological treatment), including antiplatelet agents, lipid-lowering drugs, beta-blockers, and renin-angiotensin-aldosterone system blockers, was assessed at follow-up. Differences were considered significant for p values &lt;0.05. Results From 928 patients enrolled at baseline, 415 had mild CAD and 66 moderate to severe CAD. The average follow-up was 5.2 ± 1.5 years. Patients submitted to CABG were more likely to receive the optimal pharmacological treatment than those submitted to PCI or treated clinically (63.5% versus 39.1% versus 45.7% respectively, p=0.003). Baseline factors independently associated with greater probability of having a prescription of optimal treatment at follow-up were CABG [39% higher (6% - 83%, p=0.017) and diabetes [25% higher (1% - 56%), p=0.042] than their counterparts treated by other methods and participants without diabetes, respectively. Conclusions Patients with CAD submitted to CABG are more commonly treated with optimal pharmacological secondary prevention than patients treated by PCI or exclusively with medical therapy.

title: Evaluation of the behavioral program in type 2 diabetes mellitus: a randomized clinical trial

description: Abstract The scope of this article was to evaluate the effect of the behavioral group education program and telephone intervention in modifying psychological attitudes, enhancing empowerment, and self-care practices aimed at improving clinical control in type 2 diabetes mellitus. It involved a randomized cluster clinical trial, carried out with 199 people with diabetes. In order to perform intragroup comparisons (final and initial phases) and between groups with respect to the indices of the psychological attitude, empowerment, self-care and glycated hemoglobin level variables, the Generalizing Estimating Equation (GEE) approach was used. In all analyses, a 5% significance level and 95% confidence interval were used. When compared to the CG, the IG showed a significant reduction in the mean values of glycated hemoglobin (95%CI: -1.49 to -0.45), a statistically significant increase in the change in psychological attitude scores (95%CI: 9.70 to 15.40), on the empowerment scale (95%CI: 0.81 to 2.72) and adherence to self-care practices (95%CI: 1.44 to 2.10) at the end of the study. The behavioral program proved to be capable of modifying psychological attitudes, improving empowerment, self-care practices and clinical control.

title: Gymnopilus ianthinilophus (Agaricales, Basidiomycota), a new species from the Brazilian Amazon

description: Abstract Gymnopilus is an agaricoid genus of mostly wood-rotting mushrooms, with ca. 200 species worldwide distributed, of which 23 of them are currently known in Brazil. In the Amazon region, Gymnopilus taxa correspond mostly to very old names described under Agaricus, later recombined into Gymnopilus, such as G. marasmioides, G. panurensis, G. psamminus, and G. trailii. Based on the examination of a well-annotated exsiccate at the INPA Herbarium, Gymnopilus ianthinilophus is described as a new species. It is characterized by the densely cespitose habit, squarrose pileus with blackish brown squamules, adnate to subdeccurent lamellae with decurrent tooth, violaceous brown stipe, weakly dextrinoid basidiospores 7.6-9.2 × 5.1-6.1 µm, interwoven pileus trama, lageniform with capitate or subcapitate apex cheilocystidia measuring 15.3-25.5 × 5.6-8.2 µm, and absence of pleurocystidia and caulocystidia. Description, photographs, illustrations of the new species, and discussion and comparison with morphologically similar taxa are provided.

title: Intimate partner physical violence and inadequate weight gain in pregnancy

description: Abstract Objectives: to evaluate the association between intimate partner physical violence (IPPV) and inadequate gestational weight gain (GWG). Methods: cross-sectional study composed of 554 women who attended four Basic Health Units in the city of Rio de Janeiro between 2005 and 2009. The GWG was calculated through the difference between the final weight of pregnancy and pre-gestational weight. For the measurement of IPPV, the Portuguese version of the Conflict Tactics Scales (CTS-1) was used. Data analysis was based on multinomial logistic regression models, estimating odds ratios and respective 95% confidence intervals for associations between the variables of interest. Results: the prevalence of minor and severe IPPV was 31.6% and 16.3%, respectively. Almost two-thirds of the women had insufficient or excessive GWG. After adjusting the model, it was observed that the presence of IPPV increased by 1.66 (CI95%=1.05-2.64) times the chances of insufficient GWG, compared to couples who did not experience this type of violence. Concerning the excessive GWG, the associations with IPPV were not statistically significant. Conclusion: women who experience IPPV in their relationships are more likely to have insufficient GWG during pregnancy. From this perspective, prenatal care becomes an essential service for screening domestic violence and its possible repercussions.

title: Polyunsaturated fatty acids alter the formation of lipid droplets and eicosanoid production in Leishmania promastigotes

description: BACKGROUND The knowledge about eicosanoid metabolism and lipid droplet (LD) formation in the Leishmania is very limited and new approaches are needed to identify which bioactive molecules are produced of them. OBJECTIVES Herein, we compared LDs and eicosanoids biogenesis in distinct Leishmania species which are etiologic agents of different clinical forms of leishmaniasis. METHODS For this, promastigotes of Leishmania amazonensis, L. braziliensis and L. infantum were stimulated with polyunsaturated fatty acids (PUFA) and LD and eicosanoid production was evaluated. We also compared mutations in structural models of human-like cyclooxygenase-2 (GP63) and prostaglandin F synthase (PGFS) proteins, as well as the levels of these enzymes in parasite cell extracts. FINDINGS PUFAs modulate the LD formation in L. braziliensis and L. infantum. Leishmania spp with equivalent tissue tropism had same protein mutations in GP63 and PGFS. No differences in GP63 production were observed among Leishmania spp, however PGFS production increased during the parasite differentiation. Stimulation with arachidonic acid resulted in elevated production of hydroxyeicosatetraenoic acids compared to prostaglandins. MAIN CONCLUSIONS Our data suggest LD formation and eicosanoid production are distinctly modulated by PUFAS dependent of Leishmania species. In addition, eicosanoid-enzyme mutations are more similar between Leishmania species with same host tropism.
