title: Morphological Changes in Endothelial Cell Organelles in a No-Touch Saphenous Vein Graft

description: ABSTRACT Introduction: Improved long-term patency of the no-touch (NT) saphenous vein graft has been reported to result from the preservation of a healthy vascular microstructure, especially endothelial cells. However, the precise morphology of endothelial cells and their organelles in NT saphenous vein graft has not been fully investigated. In this study, we assessed the ultrastructure of preserved endothelial cells in saphenous vein graft using transmission electron microscopy. Methods: Intact control (IC) vein, NT saphenous vein graft, and conventional (CT) saphenous vein graft were harvested from a patient. After observation by light microscopy, the nuclei and mitochondria in the preserved endothelial cells were compared among IC, NT, and CT using transmission electron microscopy, and the endothelial organelles were assessed quantitatively. Results: Light microscopy showed that the preservation of endothelial cells was comparable in IC, NT, and CT. Subsequent transmission electron microscopy observation showed that the nuclei in preserved endothelial cells appeared more swollen in CT than that in NT. Quantitative analysis revealed that nuclear size and circularity of preserved endothelial cells in NT and IC were similar, but those in CT were larger and higher, respectively, than those in IC and NT. In addition, the mitochondrial size in preserved endothelial cells in CT was larger than that in IC and NT. Conclusion: Necrotic changes in endothelial organelles characterized by swelling of nuclei and mitochondria were prominent in CT saphenous vein graft. The normally maintained ultrastructure of preserved endothelial cells in NT saphenous vein graft could contribute to long-term patency.

title: Early and Midterm Outcomes of “No-Touch” Saphenous Vein Grafts in Japanese Institutions

description: ABSTRACT Introduction: There have been several attempts to overcome the poor graft patency of saphenous vein grafts. “No-touch” saphenous vein graft (NT-SVG) could be a solution to improve graft patency. We aimed to investigate the early and midterm outcomes of coronary artery bypass grafting (CABG) using NT-SVGs in our hospitals. Methods: This is a retrospective study of 105 patients who underwent CABG using 130 NT-SVGs between August 2013 and December 2021. NT-SVGs were harvested with about a 5-mm margin of surrounding tissue on both sides of the vein with minimal manipulation. Then, the NT-SVG was dilated by natural arterial pressure without manual distension. After surgery, most of NT-SVGs were assessed by cardiac catheterization or multidetector computed tomography (MDCT) to determine early graft patency. Late graft assessments by MDCT were performed about every five years after surgery. Results: The early graft patency of NT-SVGs was 100% (125/125); however, two cases of graft twisting were found. Both cases spontaneously resolved. Leg wound infections of NT-SVG harvesting site were seen in 6.2% of patients. Peripheral neuropathy of the legs such as skin numbness and tingling were frequently observed, which lasted up to one year, but no more than two years after surgery. The midterm graft patency of NT-SVGs was excellent (five-year patency of NT-SVGs was 95.8%). Conclusion: The early and midterm graft patency of NT-SVGs was satisfactory. Although leg wound complications can be seen on the harvesting NT-SVG site, the “no-touch” harvesting technique of SVG could improve graft patency and clinical outcomes of CABG.

title: The enormity of a booklet: first edition and target audience of Thomas Davatz’s (1858) first edition of The colonists in St. Paulo province, Brazil

description: ABSTRACT The Sharecroppers’ Riot (1856-1857), which took place at Ibicaba farm, is one of the best-known episodes in the history of immigration to Brazil. Beyond its intrinsic relevance, the abundance of sources facilitated and attracted historiographical investigations about the event, particularly the account written by its leader, the schoolmaster Thomas Davatz, who published a book in 1858 with the revised version of his report on the living and working conditions in the farms of São Paulo. This article investigates the history of the writing of that book and the materiality of its first edition, published by Leonhard Hitz, in Chur, Switzerland. The titles published by Hitz and listed in the backcover of Thomas Davatz’s book give us an overview of his target audience. Based on a bibliographical survey on a sample of such books, this paper estimates the cost of Davatz’s brochure in two francs. This estimate and the materiality of the book indicate the low-cost nature of the edition, although the price was non-negligible for the poorest parcel of the population - precisely those interested in emigrating -, corresponding to ca. 10.5 hours of an average Swiss laborer in the 1850s. Finally, by studying its cover, the text raises some hypotheses regarding the editorial decisions made in the first translation into Portuguese by Sérgio Buarque de Holanda for the Biblioteca Histórica Brasileira, a collection organized by Rubens Borba de Moraes. The Brazilian translation is much aligned with the original cover title, which, to a certain extent, differs from that in the coversheet.

title: REVISITING THE NOTION OF FIELD BY PIERRE BOURDIEU TO UNDERSTAND THE PRODUCTION OF KNOWLEDGE IN BRAZILIAN PHYSICAL EDUCATION

description: ABSTRACT: This article aimed to (re) visit Pierre Bourdieu's notion of the field to understand Brazilian Physical Education as a field of non-neutral knowledge production, full of interests in power disputes. The construction of writing took place from two methodological aspects. The first was a bibliographic review of works by Bourdieu and authors of Brazilian Physical Education who studied the author. The second is based on the sociological analysis carried out on the doctoral thesis produced by one of the authors. We consider that the exercise carried out in this article allows us to think about analytical alternatives in the theoretical and methodological construction of new studies. We point out that the field is recent, under construction and permeated by academic / professional tensions that interfere with its identity. The entire route presented explains the interests of agents and institutions that play symbolically in the fabric of their conveniences. We believe it is essential to unveil the multiple elements that intend this field, mainly concerning its institutionalization, increase, and policy.

title: Predictors of Hospital Mortality Based on Primary Angioplasty Treatment: A Multicenter Case-Control Study

description: Abstract Background Identification of high-risk patients undergoing primary angioplasty (PCI) is essential. Objective Identify factors related to the causes of death in PCI patients. Methods This work consisted of a multicenter case-control study using a Brazilian registry of cardiovascular interventions as the data source. The association between each variable and death was assessed using a binary logistic regression model, p &lt;0.05 was considered significant. Results A total of 26,990 records were analyzed, of which 18,834 (69.8%) were male patients, with a median age of 61 (±17) years. In the multivariate analysis, the main variables related to the causes of death with their respective odds ratios and 95%confidence intervals (CI) were advanced age, 70-79 years (2.46; 1.64-3.79) and ≥ 80 years (3.69; 2.38-5.81), p&lt;0.001; the classification of Killip II (2.71; 1.92-3.83), Killip III (8.14; 5.67-11.64), and Killip IV (19.83; 14.85-26.69), p&lt;0.001; accentuated global dysfunction (3.63; 2,39-5.68), p&lt;0.001; and the occurrence of infarction after intervention (5.01; 2.57-9.46), p&lt;0.001. The main protective factor was the post-intervention thrombolysis in myocardial infarction (TIMI) III flow (0.18; 0.13-0.24), p&lt;0.001, followed by TIMI II (0.59; 0.41 -0.86), p=0.005, and male (0.79; 0.64-0.98), p = 0.032; dyslipidemia (0.69; 0.59-0.85), p&lt;0.001; and number of lesions treated (0.86; 0.9-0.94), p&lt;0.001. Conclusion The predictors of mortality in patients undergoing PCI were Killip’s classification, reinfarction, advanced age, severe left ventricular dysfunction, female gender, and post-intervention TIMI 0 / I flow.

title: Postharvest quality of 'Emerald' blueberry cultivated in a subtropical region

description: Abstract The objective of this work was to evaluate the qualitative attributes, at harvest and postharvest, of 'Emerald' blueberries grown in a subtropical climate region, without winter chilling, in Brazil. Fruit were harvested in the municipality of Piracicaba, in the state of São Paulo, in two harvest peaks, in August and October, and evaluated for their qualitative attributes at harvest and for their physical, chemical, and biochemical attributes at postharvest. The fruit were maintained at ambient conditions, at 22°C and 70% relative humidity, and evaluated on the day of harvest and every three days until the twelfth day of storage. The blueberries harvested in August were larger and rounder, and those harvested in October had a more intense blue coloration and higher concentrations of phenolic compounds, pH, and soluble solids, in addition to a higher total soluble solids and titratable acidity ratio. During storage, an increase was observed in the contents of anthocyanins, quercetins, and total phenolic compounds, as well as in antioxidant activity, besides a decrease in fruit acidity and firmness. Regardless of the harvest month, blueberries grown in a subtropical region of Brazil have a good postharvest shelf life up to 12 days at ambient temperature, with satisfactory fruit quality levels.

title: CAPITALISMO E DEMOCRACIA

description: Abstract There are many accounts of “right wing populism”. Some emphasize income inequality, some culture, some the specifics of particular political systems. This paper takes a step back, and provides a longer term structural view. Its central contention is that what is happening in the world today is a structural crisis of capitalist democracy. The specific political styles and causal pathways that brought men like, Trump, Bolsonaro, Duterte, and Modi to power are hard to specify. What is blindingly obvious is the increasing detachment of large parts of the population from liberal democratic forms. The underlying cause of this detachment is the unravelling of the “material basis of consent” that had marked capitalist democracies in the post-war period. Unsurprisingly this unravelling has progressed the most in precisely the periphery of the core, and the semi-periphery. It is these countries that have become the political path-breakers for the more consolidated capitalism’s of the core. I sustain these claims in what follows through a brief comparative analysis of the rise of Berlusconi in Italy who was the “canary in the coal mine” of the current wave of Bonapartist figures, and Bolsonaro who is the most important current exemplar of the type.
