title: WHAT IS WOMEN’S POSITION IN BRAZIL’S BOARD INTERLOCKING NETWORK? AN ANALYSIS COVERING THE PERIOD FROM 1997 TO 2015

description: ABSTRACT Until recently, the companies’ boards of directors have shown a strong male predominance, while controversial results regarding the insertion of women in these bodies have prevailed. Given this context, this research aimed to investigate the evolution of women’s participation in the boards of directors of Brazilian companies listed on B3 and the position of these directors in the corporate board interlock network, between 1997 and 2015. To understand this phenomenon, the Social Network Analysis (SNA) methodology was adopted and several indicators were. The results indicate that women’s participations have increased top management positions of the Brazilian corporate environment and women have begun to integrate the boards of directors, a scenario still far from the reality observed in developed countries. Nonetheless, by analyzing the members connected in the corporate network, we have concluded that women reach high proximity, since they have a high degree of centrality in the network, but they also lack the potential for intermediation. Such results signal the need to increase gender diversity at the top level of companies, which could raise the quality of debate on boards of directors and improve levels of corporate governance.

title: Probiotic Saccharomyces boulardii Alleviates Lung Injury by Reduction of Oxidative Stress and Cytokine Response Induced by Supraceliac Aortic Ischemia-Reperfusion Injury in Rats

description: Abstract Objectives: Ischemia-reperfusion injury is an important cause of multiple organ failure in cardiovascular surgery. Our aim is to investigate the effect of the probiotic Saccharomyces boulardii on oxidative stress, inflammatory response, and lung injury in an experimental model of aortic clamping. Methods: Twenty-one Wistar rats were randomized into three groups (n=7). Control group animals received saline gavage for a week before undergoing median laparotomy. In other groups, supraceliac aorta was clamped for 45 minutes to induce ischemia followed by reperfusion for 60 minutes. In the ischemia-reperfusion group, saline gavage was given preoperatively for one week. Ischemia-reperfusion+probiotic group rats received probiotic gavage for seven days before aortic clamping. The levels of oxidative stress markers and pro-inflammatory cytokines were determined in both serum and lung tissue samples. Ileum and lung tissues were harvested for histological examination. Results: Ischemia-reperfusion caused severe oxidative damage and inflammation evident by significant increases in malondialdehyde and cytokine levels (tumor necrosis factor alpha and interleukin-1 beta) and decreased glutathione levels in both serum and lung tissues. There was severe histological tissue damage to the lung and ileum in the ischemia-reperfusion group. Probiotic pretreatment before aortic clamping caused significant suppression of increases in serum and lung tissue malondialdehyde and tumor necrosis factor alpha levels. Histological damage scores in tissue samples decreased in the ischemia-reperfusion+probiotic group (P&lt;0,005). Conclusions: Oral supplementation of probiotic S. boulardii before supraceliac aortic ischemia-reperfusion in rats alleviates lung injury by reducing oxidative stress, intestinal cellular damage, and modulation of inflammatory processes.

title: COVID-19 Positive Cohort Undergoing Cardiac Surgery: A Possible Un(3H)oly Trinity of Hypoxia-Hemolysis-Hyperinflammation

description: Abstract While the fraternity continues to ponder on the mechanisms by which coronavirus disease (COVID-19) positivity affects the outcome of cardiac surgical subset, we put forth a 3H (Hypoxia-Hemolysis-Hyperinflammation) trilogy aimed at elucidating the liaison between cardiopulmonary bypass (commonly employed for cardiac surgical conduct) and COVID-19 infection. A sound comprehension of the same can doubtlessly assist the perioperative team in staging a well-directed pathophysiology-driven management approach.

title: Effect of High-Intensity Interval Training on Aerobic Capacity and Heart Rate Control of Heart Transplant Recipients: a Systematic Review with Meta-Analysis

description: Abstract Introduction: Heart transplantation (HTx) is the gold standard procedure for selected individuals with refractory heart failure. High-intensity interval training (HIIT) is safe and allows patients to exercise in high intensity for longer time when compared to moderate-intensity continuous training (MICT). The primary aim of this study was to perform a systematic review and meta-analysis about the effect of HIIT compared to MICT on exercise capacity, peak heart rate, and heart rate reserve in HTx recipients. Secondarily, we pooled data comparing MICT and no exercise training in these patients. Methods: This systematic review followed the standardization of the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement and the Cochrane Collaboration Handbook. We presented the treatment effects of HIIT on the outcomes of interest as mean difference (MD) and 95% confidence interval (CI). Meta-analysis was performed using the random-effects, generic inverse variance method. Results: HIIT improved peak oxygen consumption (peakVO2) (MD = 2.1; 95% CI 1.1, 3.1; P&lt;0.0001), peak heart rate (MD = 3.4; 95% CI 0.8, 5.9; P=0.009), and heart rate reserve (MD = 4.8; 95% CI -0.05, 9.6; P=0.05) compared to MICT. Improvements on peakVO2 (MD = 3.5; 95% CI 2.3, 4.7; P&lt;0.00001) and peak heart rate (MD = 5.6; 95% CI 1.6, 9.6; P=0.006) were found comparing HIIT and no exercise training. Conclusion: Current available evidence suggests that HIIT leads to improvements on peakVO2, peak heart rate, and heart rate reserve compared to MICT in HTx recipients. However, the superiority of HIIT should be tested in isocaloric protocols.

title: Information on food additives on food labels in Brazil: a critical analysis

description: ABSTRACT Questions about the safety of food additives and their consumption have been raised in recent years. The increased exposure to these substances, either by intake of ultra-processed foods or by the broad use and combination of various categories of additives, may be related to higher risks to consumer health. This article comments on the results of a study that quantified and characterized food additives found on the labels of 9,856 packaged foods and beverages available in Brazilian supermarkets. The study adopted a field diary method to record and analyze nonconformities in the lists of ingredients. The objective of this article is to discuss the use of additives identified on the labels and the limitations of Brazilian legislation, which should guarantee the right to information and health.

title: Oxidative Stress and Changes of Important Metabolic Gene Expressions as a Potential Biomarker in the Diagnosis of Atherosclerosis in Leukocytes

description: ABSTRACT Introduction: Presenilin 1 (PSEN1), catalase (CAT), glutathione-S-transferase (GST) and paraoxonase 1 (PON1) play a vital role in prediction, diagnosis and therapy of metabolic disorders. Methods: Metabolic enzyme activities and lipid peroxidation in serum of cerebrovascular diseases (CVD) and coronary artery diseases were measured by spectrophotometric methods. mRNA was isolated from leukocytes of the patient group and healthy adult patients. Quantitative gene expression of PSEN1, CAT and GST mRNA was identified by quantitative real-time polymerase chain reaction (qPCR). Results: The PSEN1, CAT and GST expression in patients showed significant differences compared to the control group. PSEN1 expression in leukocytes was significantly about twice as high as that of the control group in patients with CVD. The GST, CAT and PON1 activity showed significant differences in patient groups compared to the control group. Conclusion: The mRNA expression levels can be used as a potential biomarker in the diagnosis of atherosclerosis that occurs as a result of the metabolic disorder. In atherosclerotic patients, antioxidant status is independently related to an increased risk of cardiovascular events. Antioxidant activities and mRNA expressions may have predictive value, as well as available risk factors.

title: The recurring debate about the end of labor with technological unemployment

description: ABSTRACT The article analyses a recurrent question about the loss of centrality of labor with technological innovations and immaterial labor, both from a theoretical and empirical point of view. Theoretically, the centrality of labor is discussed both in relation to the theory of labor value as a form of social domination in capitalism, and in relation to the limits of technological unemployment in this mode of production. Empirically, the article presents world and Brazilian economic data on the main causes of unemployment, comparing them with technological unemployment.

title: Prognostic Value of the Leuko-Glycaemic Index in the Postoperative Period of Coronary Artery Bypass Grafting

description: Abstract Introduction: High leuko-glycaemic index (LGI) (&gt; 2000) has been associated with poor prognosis in many critical care settings. However, there is no evidence of LGI’s prognostic value in the postoperative period of coronary artery bypass grafting (CABG). This study aims to analyze the prognostic value of LGI in the postoperative period of CABG. Methods: Single-center retrospective analysis of prospectively collected data was performed. Consecutive adult patients undergoing CABG between 2007 and 2019 were included. Blood glucose levels and white blood cells count were evaluated in the immediate postoperative period. LGI was calculated by multiplying both values and dividing them by 1,000 and analyzed in quartiles. Receiver operating characteristic curve was used to determine the best cutoff value. The primary combined endpoint was in-hospital mortality, low cardiac output (LCO), or acute kidney injury (AKI). Secondary endpoints included in-hospital death, AKI, atrial fibrillation, and LCO. Results: The study evaluated 3,813 patients undergoing CABG (88.5% male, 89.8% off-pump surgery, aged 64.6 years [standard deviation 9.6]). The median of LGI was 2,035. Presence of primary endpoint significantly increased per LGI quartile (9.2%, 9.7%, 11.8%, and 15%; P&lt;0.001). High LGI was associated with increased occurrence of in-hospital mortality, LCO, AKI, and atrial fibrillation. The best prognostic cutoff value for primary endpoint was 2,000. In a multivariate logistic regression model, high LGI was independently associated with in-hospital death, LCO, or AKI. Conclusion: High LGI was an independent predictor of in-hospital mortality, LCO, or AKI in postoperative period of CABG. It was also associated with higher in-hospital death.

title: Therapeutic limitation for children: a systematic review on end-of-life

description: Abstract This systematic review sought to identify difficulties faced by professionals in the clinical management of end-of-life child patients. Bibliographic search was conducted on the SciELO and LILACS databases using the descriptors “therapeutic limitation,” “hospice care” and “comfort measures,” combined with the descriptor “child.” Of the 102 complete studies identified, nine met the established inclusion criteria. The results point to difficulties regarding decision making and therapeutic limitation for infant patients. In conclusion, when professionals feel better prepared to address issues related to the process of death and dying, they can provide more humanized care to patients and families.
