According to WHO’s weekly operational report, published on 16th February 2021, we have 110,384,747 confirmed cases and 2,446,008 deaths globally (https://www.who.int/emergencies/diseases/novelcoronavirus-2019/situation-reports). SARS-CoV-2 has been highly infectious, and it did not take long to cross the borders of China and soon become a global health threat with implications of unpredictable magnitude[1]. Noticeably, the rate of new infections is still high, with more than 2.7 million new cases per week, and there is a great concern regarding public health events associated with SARS-CoV-2 variants. Concerning cardiac surgery units, there was a clear impact on the daily routine in different ways[2-5]. Many changes took place regarding admission procedures, aggressive infection mitigation strategies in the operating room and during surgical recovery, intensive care guidelines and restrictions. Also, a necessity rose to postpone elective cardiac surgeries, to manage healthcare workers’ resources differently, to deal with the increased risk of infection for both patients and health professionals, along with the exaggerated skepticism among patients, affecting their willingness to undergo a cardiac surgery. In an international survey during the first wave of the pandemic, with the participation of more than 600 cardiac surgeons from America, Europe, Asia, and Australia, a median reduction in the volume of cardiac surgery cases was 50% to 75%, as most centers postponed elective cases and more than one-third of the centers reported more than 50% reductions in intensive care capacity[6]. This led to modifications in policies and guidelines regarding cardiac surgery priority to confront the pandemic requirements and scarce resources. However, these recommendations should be considered on case-by-case basis with a clear need for regular updates[7-9].

Methods Initially, healthy male Sprague Dawley rats were treated with streptozocin to induce diabetes. Then, three weeks after the induction, Dex or lentiviral vector (LV)-HIF-1α was injected into the rats 30 minutes prior to the MIR modeling. After four weeks, lung tissues were harvested for pathological changes observation and the wet/dry weight (W/D) ratio determination. Afterwards, oxidative stress indicators and pro-inflammatory factors were measured. In addition, HIF-1α expression was assessed by immunohistochemistry and western blot analysis. Results Dex could suppress inflammatory cell infiltration, improve lung tissue structure, reduce pathological score and the W/D ratio, and block oxidative stress and inflammatory response in MIR-induced ALI of diabetic rats. Besides, Dex could also inhibit HIF-1α expression. Moreover, Dex + LV-HIF-1α reversed the protective role of Dex on diabetic MIR-induced ALI. Conclusion Our study has made it clear that Dex inhibited the upregulation of HIF-1α in diabetic MIR-induced ALI, and thus protect lung functions by quenching the accumulation of oxygen radical and reducing lung inflammatory response.","PeriodicalId":54481,"journal":{"name":"Revista Brasileira De Cirurgia Cardiovascular","volume":"37 1","pages":"370 - 379"},"PeriodicalIF":0.0,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41581867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Culprits for Retrosternal Deformation After Coronary Artery Bypass Surgery","authors":"Abdulkerim Özhan, M. Baştopçu","doi":"10.21470/1678-9741-2021-0507","DOIUrl":"https://doi.org/10.21470/1678-9741-2021-0507","url":null,"abstract":"We have read with interest the article “Retrosternal Deformations after Coronary Artery Bypass Surgery Using Statistical Shape Analysis” by Bademci et al.[1] The authors have used novel statistical methods to demonstrate geometric changes in the mediastinum following coronary artery bypass grafting (CABG) surgery. The authors conclude that, following CABG, “the main pulmonary artery approximates to the sternum” with “narrowing of the retrosternal area”. They attribute this finding to the formation of scar tissue and adhesions which are the result of inflammation associated with cardiac surgery. We would like to inquire if the authors believe operative techniques affect the geometric changes in the mediastinum. Surgeons vary greatly in their CABG techniques, choice of grafts, pericardial closure, and use of cardiopulmonary bypass (CPB). On-pump CABG may precipitate inflammatory processes more potently compared to off-pump CABG[2]. Another technique that produces less inflammation is the mini-extracorporeal circulation (MECC) during CABG[3]. Therefore, postoperative adhesions and scar tissue formation could be attenuated in patients who are revascularized with offpump CABG or using MECC. It is also possible that CPB times, blood transfusions, perioperative medications, and patient factors affect the amount of inflammatory response in the postoperative period. Data related to CPB and other factors that induce inflammation in the patient group in the study may be relevant. The cannulation strategy is also important, as central arterial cannulation may result in more retrosternal adhesions than femoral cannulation. The placement of a pulmonary vent catheter and the extent of tissue dissection around the pulmonary artery may influence the adhesions present in the postoperative period. For their statistical shape analysis, the authors have compared patients with previous CABG with a control group without a history of cardiac surgery. In our opinion, this overlooks interpersonal geometric differences in mediastinal anatomy. The size of the great vessels can be different in the population of patients who require cardiothoracic surgery than individuals who did not require an operation. Comorbidities accompanying heart diseases, including, but not limited to, aortic enlargement or elevated pulmonary pressure increasing great vessel diameters, may complicate the comparison of retrosternal distance[4]. If the authors can identify a cohort of patients who had chest computed tomography before and after surgery, their methods can be applied to distinctly assess the effect of CABG surgery on retrosternal adhesions. This would also allow controlling or comparing other important factors in inflammation. We congratulate the authors for their study in the underexplored field of retrosternal adhesions in cardiac surgery. The findings from this study can guide cardiac surgeons who face the perils of retrosternal adhesions in redo operations.","PeriodicalId":54481,"journal":{"name":"Revista Brasileira De Cirurgia Cardiovascular","volume":"37 1","pages":"422 - 422"},"PeriodicalIF":0.0,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45622326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods Case studies and relevant research articles were analyzed to understand the recent advances in medical scientific knowledge on TBAA. Recent clinical case reports on TBAA were searched from the year 2010 to 2020. Results Case reports indicated a higher prevalence of TBAA in the male population. The most affected age group was 15 to 79 years. The most common treatment for TBAA included surgery followed by antituberculous medication. The case reports discussed in this review reflected open surgery, endovascular repair, coil embolization, laparotomy, aortic valve and root replacement as some of the surgical procedures used depending on the complication and type of aneurysm. The treatment outcome was considered effective in most cases. Conclusion Postoperative chemotherapy and medications reduce the risk of severity. Early diagnosis of TBAA is imperative, followed by surgical resection and postoperative antituberculous medication with careful follow-up to prevent relapse.","PeriodicalId":54481,"journal":{"name":"Revista Brasileira De Cirurgia Cardiovascular","volume":"37 1","pages":"385 - 393"},"PeriodicalIF":0.0,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48015779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Warfarin is widely used by the Brazilian population, possibly due to its lower cost than other oral anticoagulants. However, it has a high risk of serious adverse effects if used incorrectly. The Anticoagulation Knowledge Tool (AKT) can assess a patient’s knowledge about her/his oral anticoagulant therapy and can assist health professionals in identifying patients with difficulties in adherence. This study aimed to translate, culturally adapt, and validate the AKT into Brazilian Portuguese. Methods After a standard forward-backward procedure to translate the AKT into Brazilian Portuguese (AKT-Br), a version of the instrument was applied in three groups (patients, pharmacists, and the general population). The reliability of the AKT-Br was tested using an internal consistency measure and test-retest. The validity of the instrument was confirmed with data from the contrasted groups. All statistical analyses were performed with RStudio. Results The median scores obtained with the AKT-Br were 29.0, 17.0, and 7.5 for pharmacists, patients, and the general population, respectively (maximum score of 35 points). There was moderate internal consistency for the instrument and test-retest reliability was satisfactory. Analysis of variance for validity of the groups revealed a significant relationship between the total score and the evaluated groups. Conclusion The ATK-Br is a reliable and valid tool to assess knowledge about oral anticoagulants. AKT-Br can be used in clinical practice as an auxiliary tool to improve patient care through personalised educational interventions.","PeriodicalId":54481,"journal":{"name":"Revista Brasileira De Cirurgia Cardiovascular","volume":"37 1","pages":"356 - 369"},"PeriodicalIF":0.0,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42297557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some prostheses available in the market cannot be fractured. In an ex vivo test, the possibility of ring fracture of aortic valve bioprostheses produced in Brazil when submitted to radial force application using a high-pressure non-compliant balloon was evaluated. Methods One unit of each aortic valve bioprosthesis model, sizes 19 and 21 mm, produced by Brazilian companies (Braile Biomédica, Cardioprótese, and Labcor), was used. In the experiment, a non-compliant high-pressure balloon (Atlas®-Gold), 1 mm larger than the external diameter of the prosthesis, was positioned inside the valve annulus and inflated gradually aiming to fracture the prosthesis. Fracture pressures and photographic and radiological images of the prostheses before and after test were recorded. Results All prostheses were fractured. In the models with metal ring, the fracture pressures were between 23 and 25 atm. In the other prostheses, the rupture occurred between 10 and 13 atm. No deformations in the structure were observed, which could potentially damage the aortic root. Conclusion All the Brazilian prostheses evaluated were fractured, although the presence of a metal ring in the prosthesis framework increases the pressure required for fracture. The information obtained helps in the planning of valve-in-valve procedures in patients with aortic valve bioprostheses.","PeriodicalId":54481,"journal":{"name":"Revista Brasileira De Cirurgia Cardiovascular","volume":"37 1","pages":"301 - 305"},"PeriodicalIF":0.0,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42345510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Beyan et al.[1] commented that “The control group did not consist of healthy volunteers, and it was made up of individuals who applied in the hospital at the same time. The fact that the control group is not composed of healthy volunteers and does not represent the society makes it difficult to interpret the results obtained.”. Our study results have a statistically significant value, and while we have excluded the patients previously diagnosed with hematological malignancy, chronic obstructive pulmonary disease (or COPD), autoimmune liver disease, cirrhosis, metastatic bone marrow infiltration, acute or chronic inflammatory disease — such as physical trauma, tonsillitis, asthma, rheumatoid arthritis, and active hepatitis —, and current or recent treatment (in the past three months) with oral or intravenous steroids or other medications that might cause pancytopenia from the control group according to their background, it is possible that all the exclusion criteria cannot be made in a retrospective study and that there can be pre-analytical and analytical errors, but this does not change the statistical difference. Additionally, Beyan et al.[1] tried to draw attention that mean platelet volume (MPV) is a complete blood count parameter whose measurement has not been standardized to date and, therefore, it has been reported to have no role in diagnosis and prognosis of acquired diseases according to a study, but there are many studies about the prognostic value of MPV in many clinical diseases. Vardon-Bounes et al.[3] reported that MPV was an independent predictive factor of 90-day mortality. They suggested that continuous monitoring of MPV may be a useful parameter to stratify mortality risk in septic shock. Ma et al.[4] reported that high MPV can be considered as an independent biomarker for predicting three-month mortality in patients with hepatitis B virus-related decompensated cirrhosis.
