Methods In a simulated strong geomagnetic outbreak, the MI/RI rat models were radiated, and their area of myocardial infarction, hemodynamic parameters, creatine kinase (CK), lactate dehydrogenase (LDH), melatonin, and troponin I values were measured after a 24-hour intervention. Results Our analysis indicates that the concentrations of troponin I in the geomagnetic shielding+operation group were lower than in the radiation+operation group (P<0.05), the concentrations of melatonin in the shielding+operation group and normal+operation group were higher than in the radiation + operation group (P<0.01), and the concentrations of CK in the shielding + operation group were lower than in the radiation + operation group and normal + operation group (P<0.05). Left ventricular developed pressure (LVDP) and ± dP/dtmax in the radiation+operation group were lower than in the shielding + operation group and normal+operation group (P<0.01). Left ventricular end-diastolic pressure (LEVDP) in the shielding + operation group was higher than in the normal + operation group (P<0.05). There was no significant difference in area of myocardial infarction and LDH between the shielding + operation group and the radiation + operation group. Conclusion Our data suggest that geomagnetic activity is important in regulating myocardial reperfusion injury. The geomagnetic shielding has a protective effect on myocardial injury, and the geomagnetic radiation is a risk factor for aggravating the cardiovascular and cerebrovascular diseases.","PeriodicalId":54481,"journal":{"name":"Revista Brasileira De Cirurgia Cardiovascular","volume":"34 1","pages":"674 - 679"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43477956","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}

However, in recent years, information technology has significantly impacted medical practice, and with this, several challenges have emerged, such as the provision and dissemination of health care information. With the constant growth of health research, falsification, plagiarism, and data fabrication have been having a deleterious effect on the results presented. Unethical conduct in research drains the foundations of science which, by their very nature, are built on previous evidences, and if these are false, these foundations are logically weakened. In this context, it is up to the hard work of the editors of major scientific publications to ensure to the researchers and the society the dissemination of papers with reliable and transparent results. Research misconduct means fabrication, falsification, or plagiarism in proposing, performing, or reviewing research, or in reporting research results[1]. It is important to point out that misconduct does not include honest mistakes or differences of opinion. Scientific integrity consists in sticking to strategies that allow the promotion and development of ethical and honest scientific standards that guarantee objectivity, clarity, reproducibility, openness, and accessibility, the caring duty, fairness in providing references and giving credit, and responsibility to future scientists and researchers. This is one of the main concerns that scientific editors face daily, and this topic has been included in the Brazilian Journal of Cardiovascular Surgery’s (BJCVS) new instructions.

Fatahian","doi":"10.21470/1678-9741-2019-0309","DOIUrl":"https://doi.org/10.21470/1678-9741-2019-0309","url":null,"abstract":"Despite developing new standards and advances in anesthetic and surgical techniques, postoperative atrial fibrillation (POAF) is one of the most frequent complications and a significant unsolved clinical problem after cardiac surgery[1]. Occurrence of POAF is associated with significant increased risk of long-term mortality, morbidity, and long intensive care unit (ICU) and hospital stays, which consequently impose additional cost on both health system and patient[2]. Considering the potential significant adverse effects of POAF in patients undergoing cardiac surgery and the limited efficacy of current preventive strategies, concerted efforts to identify and implement new preventive strategies are necessary[1,2]. Recently, injection of botulinum toxin into epicardial fat pads in patients undergoing cardiac surgery has been suggested as a promising modality for prevention of POAF. In a study by Pokushalov et al.[3], it has been shown that 50 U botulinum toxin injection, at four major epicardial fat pads, during surgery in patients undergoing coronary artery bypass grafting (CABG) provided considerable atrial tachyarrhythmia suppression, in both early and one-year followups[3]. Also, a three-year follow-up of this study indicates a sustained and significant reduction in atrial fibrillation (AF) incidence and burden, along with reduction in patients' hospitalizations. Besides, no serious adverse events related to injection of botulinum toxin for prevention of POAF after CABG have been reported[4]. Suppression of atrial autonomic remodeling has been suggested as a potential mechanism of botulinum toxin injection for prevention of POAF[34]. Another study by Waldron et al.[5] showed that injection of 50 U of botulinum toxin into each five epicardial fat pads (immediately after beginning of cardiopulmonary bypass) in patients undergoing cardiac surgery reduced the incidence of POAF compared to placebo (36.5% and 47.8%, respectively), however this difference was not statistically significant. Also, no significant differences were seen between length of hospital stay and occurrence of adverse effects in patients who received botulinum toxin injection or placebo[5]. In this study, patients who underwent CABG or valve surgery or combined CABG and valve surgery were included; whereas in Pokushalov et al.[3] one-year and three-year follow-up studies[4], only CABG patients were included and evaluated. Additionally, the left atrial sizes, as a marker of atrial structural remodeling, which commonly is associated with increased risk for AF, were considerably different between these studies (3.9±0.6 and 3.9±0.7 cm vs. 4.7±0.8 and 4.8±0.6, respectively). These issues may be possible explanations for the inconsistent results between studies. In sum, it seems that botulinum toxin injection into epicardial fat pads may be considered as a potentially promising and safe modality for prevention of POAF after cardiac surgery. However, further well-designed studies will be","PeriodicalId":54481,"journal":{"name":"Revista Brasileira De Cirurgia Cardiovascular","volume":"34 1","pages":"643 - 643"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49209640","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}

It is believed that interventions for these diseases on overtime hours (night shifts or weekend shifts) may increase mortality. In this study, we investigated the effect of performing acute type A aortic dissection surgery on overtime hours in terms of postoperative outcomes. Methods 206 patients who underwent emergency surgery for acute type A aortic dissection were retrospectively evaluated. Two groups were constituted: patients operated on daytime working hours (n=61), and patients operated on overtime hours (n=145), respectively. Results Chronic obstructive pulmonary disease and repeat surgery were higher in group 1. There was no statistically significant difference between the two groups in terms of operative and postoperative results. Mortality rates and postoperative neurological complications in group 1 were 9.8% and 13.1%, respectively. In group 2, these rates were 13.8% and 12.4%, respectively (P=0.485 - P=0.890). Multivariate analysis identified that cross-clamp time, amount of postoperative drainage, preoperative loss of consciousness and postoperative neurological complications are the independent predictors of mortality.

Methods This is a double-blind randomized clinical trial study. Fifty patients (50-80 years old) who had CABG surgery were selected. The intervention group received 5 g of intravenous vitamin C before anesthesia induction and 5 g of vitamin C in cardioplegic solution. The control group received the same amount of placebo (normal saline). Arterial blood samples were taken to determine the serum levels of CK-MB, troponin I, and LDH enzymes. Left ventricular ejection fraction was measured and hemodynamic parameters were recorded at intervals. Results High doses of vitamin C in the treatment group led to improvement of ventricular function (ejection fraction [EF]) and low Intensive Care Unit (ICU) stay. The cardiac enzymes level in the vitamin C group was lower than in the control group. These changes were not significant between the groups in different time intervals (anesthesia induction, end of bypass, 6 h after surgery, and 24 h after surgery) for CK-MB, LDH, and troponin I.
