title: Oral hyperpigmentation as an initial clinical aspect of hand foot syndrome

description: Abstract Hand-foot syndrome (HFS) is a common adverse effect of anticancer therapy. It is known to cause dermatological symptoms including acral erythema and dysesthesia of the palms and soles of the feet, swelling, pain, itching, and scaling. Some drugs, like capecitabine, are known to trigger this condition. However, pigmentation of the oral mucosa is a rare adverse effect. This study aims to report a case of oral mucosa hyperpigmentation caused by capecitabine therapy before the clinical diagnosis of HFS. A 58-year-old female, diagnosed with invasive breast duct carcinoma, had the central nervous system, liver, skin, and lung metastasis, using capecitabine every day for 14 cycles. Oral examination revealed multifocal black macules on the hard palate, bilateral buccal mucosa, gingival mucosa, and dorsum of the tongue. The clinical hypothesis was oral mucosa hyperpigmentation by capecitabine use and only periodic follow-up was necessary. Hyperpigmentation of oral mucosa by capecitabine is a rare consequence of neoplastic therapy and your association with HFS is unclear, and poorly reported. The report of these events is important to alert oncology health teams about the individual tolerance to capecitabine therapy.

title: Growth, centralization, and financialization of Diagnostic and Therapeutic Support Services (SADT) in Brazil: a study of selected companies from 2008 to 2016

description: This article discusses the dynamics of the Diagnostic and Therapeutic Support Services subsector from 2008 to 2016 in Brazil. Through an exploratory approach, the study aimed to operationalize key concepts from the literature on the pattern of accumulation characterizing contemporary capitalism. The research focused on the activity of six Brazilian diagnostic companies in three main dimensions: (1) net worth; (2) accounting-finance; and (3) policy. The results reveal a subsector experiencing vigorous growth via increases in the volume and prices of the services provided. The evidence corroborates traits of a pattern of financialized accumulation, especially aggressive strategies of mergers and acquisitions by leading companies, with centralization as a result. However, some characteristics associated with the concept of financialization appear not to be relevant. The article also discusses the prospects for competition in activities in the Diagnostic and Therapeutic Support Services subsector and the possible effects for the effort to consolidate Brazilian Unified National Health System (SUS).

title: Between subordinates and hosts: the complex relationship between women and History

description: ABSTRACT This article aims to analyze Judy Chicago’s work of art, The Dinner Party, in the light of the concepts developed by the Women’s History. Such relationship occurs through the interpretation of the work of Chicago from the context in which it was conceived, that of the second wave of the feminist movement that contributed to the development of the Women’s History as a theoretical field. The studies inserted in the Women’s History, however, are not limited to just pointing out the existence of women throughout History, but also raises questions about the reason and how they were erased. Chicago’s work, rich in symbolism, was chosen precisely because it closed these two biases present in the these epistemological assumptions, connecting the affirmation of identities, the recovery of memories and the re-reading of a History defined by the genre.

title: ANALYSIS OF THE MECHANICAL BEHAVIOR OF THE POSTERIOR CRUCIATE LIGAMENT IN A PORCINE MODEL

description: ABSTRACT Introduction: The knee has shown a significant increase in the frequency of injury due to sports practice. This increase and the improvement of surgical techniques of ligament reconstruction have led to a greater indication of this treatment to achieve a function close to normal. Objective: To conduct a preliminary analysis of the ligament behavior. Methods: The study consisted of the validation of an anatomical model of the pig, in which five models were subjected to mechanical tests. The data on the loads of the in situ model and the strains of the posterior cruciate ligament were collected. Results: The analysis of the tensile load showed, at first, a nonlinear increase in stresses. Subsequently, the pig’s knee showed a relatively linear intermediate response until failure around 1,200 N. Strain × time showed a response of the posterior cruciate ligament, which also has a relatively linear response. Conclusion: We observed a linear behavior in the range of 1,000 to 5,000 microstrains in the strain of the posterior cruciate ligament. We suggest further studies to understand knee ligaments regarding their behavior in their function. Level of Evidence IV, Biomechanical Study.

title: Recent changes and continuity of technological and economic dependency in the pharmaceutical industry in Brazil

description: This article presents the results of a study on the pharmaceutical industry in Brazil in the recent period, as part of the multicenter project Health Economic-Industrial Complex, Innovation and Capitalist Dynamics: Structural Challenges for Construction of the Universal Health System in Brazil. The four components studied in the evolution of the Brazilian pharmaceutical industry were: State industrial policies; changes in the financial and shareholding composition of companies with domestic capital; trends in production; and trade balance behavior. The analyses considered the theoretical framework proposed by Luiz Filgueiras and Reinaldo Gonçalves concerning the implementation of a “liberal and peripheral model” in the Brazilian economy since the 1990s. Data were collected and analyzed on the situation with the Product Development Partnerships (PDP) for medicines from 2009 to 2020 from the Annual Industrial Survey (PIA) of the Brazilian Institute of Geography and Statistics (IBGE) from 1996 to 2018 and data on the evolution of the sector’s trade balance from 1996 to 2019. The results show that the State’s agenda for the sector favored the growth in production of generic drugs and over-the-counter drugs and started some technology transfer projects via PDPs for production of biological and synthetic drugs. Despite this evolution, Brazil is still dependent on the importation of chemical and pharmaceutical inputs and finished drugs. This keeps Brazil in a situation of technological and economic vulnerability in relation to global suppliers, besides a growing trade deficit in the sector.

title: Comparison Between Treatment Strategies of Carotid Stenosis in Patients Undergoing Coronary Artery Bypass Grafting

description: ABSTRACT Introduction: In patients undergoing coronary artery bypass grafting (CABG), stroke is a major complication that increases morbidity and mortality. The presence of carotid stenosis (CS) increases risk of stroke, and the optimal treatment remains uncertain due to the lack of randomized clinical trials. The aim of this study is to compare three management approaches to CS in patients submitted to CABG. Methods: From 2005 to 2015, 79 consecutive patients with significant CS submitted to CABG were retrospectively evaluated. Patients were divided in three groups, according to CS treatment: 17 underwent staged carotid endarterectomy (CEA)-CABG, 26 underwent synchronous CEA-CABG, and 36 underwent isolated CABG without carotid intervention. The primary outcomes were composed by 30-day postoperative acute myocardial infarction (MI), 30-day postoperative stroke, and death due to all causes during the follow-up. Results: Patients were evaluated during an average 2.05 years (95% confidence interval = 1.51-2.60) of follow-up. Major adverse cardiac events, including death, postoperative MI, and postoperative stroke, occurred in 76.5% of the staged group, 34.6% of the synchronous group, and 33.3% of the isolated CABG group (P=0.007). As for MI, the rates were 29.4%, 3.85%, and 11.1% (P=0.045), respectively. There was no statistically significant difference in total mortality rates (35.3%, 30.8%, and 25.0%, respectively; P=0,72) and stroke (29.4%, 7.7%, and 8.3%, respectively; P=0,064) between groups. Conclusion: Staged CEA-CABG is associated with higher major adverse cardiac events and MI rate when compared to the strategy of synchronous and isolated CABG, but without statistically difference in total mortality during the entire follow-up.

title: 2-(Pyridin-4yl)benzothiazole and Its Benzimidazole-Analogue: Biophysical and in silico Studies on Their Interaction with Urease and in vitro Anti-Helicobacter pylori Activities

description: In this study, the interaction between benzothiazole (BTA, concentration of a drug required for 50% inhibition in vitro (IC50) = 0.77 mM) and benzimidazole (BIA, IC50 = 2.14 mM) with urease was quantitatively assessed, using UV-Vis, molecular fluorescence, and circular dichroism. The results showed that both compounds interact with urease by a static fluorescence quenching mechanism with a non-fluorescent complex formation. The main forces responsible for stabilizing the supramolecular complex between BTA and urease were hydrophobic while, for BIA, van der Waals interactions and hydrogen bonds were the main ones. Urease conformation changes due to the interaction process were analyzed by circular dichroism and synchronous fluorescence. Besides, a competitive assay with substrate and inhibitors was used to evaluate the preferential urease site of interaction with BTA and BIA. Our experimental and theoretical studies supported that both, BTA and BIA, are mixed-inhibitors of ureases with a slight preference to the active site of such enzymes. Finally, both BTA and BIA showed to possess anti-Helicobacter pylori (one reference strain and six clinical isolates) activity, presenting minimal inhibitory concentration (MIC) values ranging from 38-150 and 20-164 µM, respectively. The urease inhibitors omeprazole and hydroxyurea showed MIC values in the range of 46-185 µM and 1683-&gt; 3366 µM, respectively.

title: From community pharmacies to big pharmacy chains: private provision of medicines, health system, and financialization of the Brazilian retail pharmacy market

description: The provision of medicines in Brazil is marked by the predominance of private expenditures and supply in pharmacies and by the historically liberal regulation of retail drug sales. The first two decades of the 21st century witnessed the expansion and concentration of the retail pharmaceutical sector and growing financialization of the health sector. The article analyzes the characteristics of financialization of Brazilian retail pharmaceutical companies, considering the following three crosscutting dimensions: ownership structure, financial/accounting, and political. Quantitative and qualitative data from various sources were analyzed including ownsership and account informations of the ten biggest Brazilian retail pharmacies chains and political action of four business associations. The information collected was stored in the source project database. The ownership structure dimension revealed verticalization, diversification, capitalization via financial and shareholding operations, intensification of mergers and acquisitions, opening of pharmacy branches, entry of investors, and changes in internal management and organization. The financial/accounting dimension revealed an increase in size (revenues, assets, net worth) and good performance (return on equity capital, capital turnover, and third-party capital) of the networks compared to Brazilian companies and health companies. The policy arena revealed both clashes and collaborations between representative associations and government (Executive, Legislative, and Judiciary), depending on the issue, with outcomes that were generally favorable to the pharmaceutical sector and leadership by the Brazilian Association of Pharmacy and Drugstore Networks (Abrafarma). The financialization of the retail pharmaceutical companies’ accumulation pattern and the strengthening of their political action proved relevant for understanding the changes in the provision of medicines and in the pharmaceutical market.
