title: Current account equilibrium exchange rate in Colombia (2000-2020)

description: ABSTRACT Using estimations by Bresser-Pereira et al. (2021), this paper analyses the misalignment between the real exchange rate and the current account equilibrium exchange rate in Colombia in the last two decades (2000-2020). Evidence suggests that the commodity boom and bust cycle in this period is important to explain (i) the main trend of the misalignment, (ii) the deterioration of the current account in recent years and (iii) the general macroeconomic performance of the Colombian economy. A discussion about macroeconomic development and stability is also provided in the context of the Colombian financial configuration, characterized by a flexible exchange rate regime, central bank independence and inflation targeting. Ideas in this paper are consistent with key elements in the New Developmentalism Theory.

title: Disclosure of information in medicine: analysis of judicial cases

description: Abstract Consent expresses a voluntary decision, taken after disclosure of information, to accept treatment considering risks, benefits, and possible consequences. This study analyzed the role of consent forms in decisions by the São Paulo State Court of Justice. Bibliographic search was conducted using the keywords “consent form” and “medical error.” The 65 rulings identified were analyzed using Excel. Of the 15 cases in which patients were not presented with a consent form, 12 showed lack of information disclosure. In 31% of the cases, the defendant was found guilty, and most of the plaintiffs who received financial compensation were awarded moral damages. Plastic surgery, gynecology and obstetrics were the branches that most often featured as defendants. The findings attest the relevant role played by the consent form and the medical expert.

title: Evaluation of Plasma Asprosin Concentration in Patients with Coronary Artery Disease

description: Abstract Introduction: The goal of this study is to investigate the association between diagnosis and severity of coronary artery disease (CAD) and Asprosin level. Methods: Patients diagnosed with CAD who underwent conventional coronary angiography for the first time were included in the present study. The patients were divided into four groups, each consisting of 20 individuals, as medical group, single coronary lesion group, double coronary lesion group, and multiple coronary lesions group. Serum Asprosin values and Gensini scores of the groups were compared in terms of compliance. Results: In this study, Asprosin values were found to be significantly higher in the multiple coronary lesions group than in the medical, single coronary, and double coronary lesion groups (P&lt;0.05). In the double coronary lesion group, Asprosin values were significantly higher (P&lt;0.05) than the in the medical and single coronary lesion groups. It was also found that Asprosin values did not differ at significant levels in the medical and single coronary lesion groups (P&gt;0.05). It was determined that the increases in Asprosin values and Gensini scores were compatible with each other. Conclusion: The present study showed that the increases in serum Asprosin levels, along with the increases in the number of coronary arteries with critical stenosis, might be a marker in diagnosing and determining the severity of CAD.

title: Pericardial-Peritoneal Window as an Alternative Treatment for Large and Recurrent Pericardial Effusion Post-Pericardiotomy

description: Abstract Introduction: The presence of mild to moderate pericardial effusion after cardiac surgery is common and oral medical therapy is usually able to treat it. Larger effusions are less frequent and surgical intervention is usually necessary. However, there are some rare cases of large effusions that are recurrent even after intervention and become challenging to treat. Methods: We describe the case of a patient submitted to coronary artery bypass grafting (CABG) without any intraoperative complications, who was regularly discharged from the hospital. She was referred to our emergency department twice after surgery with large pericardial effusion that was drained. Even after those two interventions and with adequate oral medication, the large effusion recurred. Results: During follow-up, the patient had her symptoms resolved, with no need for further hospital admission. Her echocardiograms after the last intervention showed no pericardial effusion. The present surgical technique demonstrated to be easy to perform, thus it should be considered as a treatment option for these rare cases of large and repetitive effusions, which do not respond to the traditional methods. Conclusions: In challenging cases of recurrent and large pericardial effusions, the pericardial-peritoneal window is an alternative surgical technique that brings clinical improvement and diminishes the risk of cardiac tamponade.

title: The role of the State on foreign direct investment regulation in China

description: ABSTRACT This article intends to corroborate the argument advocated by heterodox economists such as Akyüz, Chang and Furtado that state regulation is crucial to extracting the possible benefits of foreign direct investment (FDI). We do so by analyzing the policies used by China since its opening to this type of investment in 1979. The article innovates by scrutinizing China’s major FDI laws, regulations and guidelines that compose the formal framework under which foreign-owned enterprises have operated in the country for almost 40 years. We then address the traditional view that China developed simply because it increasingly opened its market to foreign investment and adopted a foreign investment-led growth model. We argue that it was because of this strong regulation that FDI had such a positive effect, contributing to technological transfer and trade expansion, although not defining the ratio of capital accumulation.

title: Impact of Early and Regular Mobilization on Vital Signs and Oxygen Saturation in Patients Undergoing Open-Heart Surgery

description: Abstract Introduction: This quasi-experimental study aimed to evaluate the impact of early and regular mobilization on vital signs and oxygen saturation in open-heart surgery patients. Methods: The study universe comprised patients undergoing open-heart surgery in the cardiovascular intensive care unit of a heart center. The study sample consisted of patients who underwent open-heart surgery from November 2016 to April 2017, met the inclusion criteria, and voluntarily agreed to participate in the study. The study included 75 patients. Of these, 67 completed the mobilization program in two days, starting on the first postoperative day. Each patient was mobilized three times: twice on the first postoperative day and once on the second postoperative day. Vital signs and oxygen saturation for each patient were measured 10 minutes before and 20 minutes after each mobilization. Results: The difference between pulse and systolic blood pressure values measured before and after the first mobilization was statistically significant (P&lt;0.05). In addition, the difference between the mean systolic blood pressure values before the first mobilization and after the third mobilization (123.43±14.09 mmHg and 117.94±14.05 mmHg, respectively) was statistically significant (P&lt;0.05). The other parameters measured in relation to the mobilizations were in the normal range. Conclusion: Early and frequent mobilization did not cause vital signs and oxygen saturation to deviate from normal limits in open-heart surgery patients.

title: The Current Role of Surgery in the Treatment of Cardiac Metastases from Malignant Melanoma: an Educational Presentation

description: Abstract A 71 year-old male with a history of multiple excisions of an initial Clark's level V melanoma of the breast followed by combined radiation and interferon treatment, as well as a recurrence, 3 years later, of a BRAF-positive tumor of the shoulder, with subsequent therapy with dabrafenib and trametinib, presented again with progressive intracardiac masses causing significant right ventricular outflow obstruction. Additionally, the patient complained of dyspnea and fatigue on exertion, thus he was scheduled for surgical resection.

title: Traversing the Learning Curve Associated with a New Minimal Access Aortic Valve Replacement Service

description: Abstract Objective: Isolated aortic valve replacement is a safe and frequently performed cardiac surgical procedure. Although minimal access approaches including right anterior thoracotomy and partial sternotomy have been adopted by some surgeons in recent years, concerns about additional procedural morbidity and mortality during the early phase of the learning curve persist. The aim of this study was to assess the impact of the learning curve on outcomes for a single surgeon implementing a new minimal access aortic valve replacement service. Methods: Ninety-three patients undergoing minimal access aortic valve replacement performed by a single surgeon in our institution between October 2014 and March 2019 were analysed. Patients were divided into tertiles according to procedure order. Endpoints included peri-operative mortality and post-operative complications, and these were compared across tertiles to assess the impact of the learning curve on procedural outcomes. Results: Overall in-hospital mortality was 2.15% (n=2). Despite significantly longer cardiopulmonary bypass and cross-clamp duration in the early tertile, there was no significant difference in the rate of post-operative complications, post-operative length of stay or in-hospital mortality between tertiles. Conclusions: Although our results have demonstrated a significant learning curve effect associated with the introduction of this minimally invasive approach to aortic valve replacement, as demonstrated by the significant reduction in cardiopulmonary bypass and cross-clamp duration over time, our findings suggest that a minimal access aortic valve replacement service can be safely commenced by an experienced surgeon without concerns about the learning curve significantly affecting post-operative morbidity and mortality.

title: Effect of Ammonia Gas in Poultry Litter Contaminated with Salmonella Heidelberg

description: ABSTRACT Salmonella Heidelberg is an emerging pathogen in Brazilian poultry production. The traditional methods (quicklime, windrowing and tarpaulin-on-surface) used for disinfecting reused poultry litter between flocks does not guarantee its elimination, thus allowing the transmission of this agent from one flock to another. The new tarpaulin-on-surface method with controlled injection of ammonia gas has proven to be effective in its control, however, it is still unknown what dose of ammonia gas is needed to eliminate Salmonella Heidelberg in reused poultry litter. The objective of this study was to evaluate the effect of ammonia gas at different concentrations in sterile poultry litter artificially contaminated with Salmonella Heidelberg. Then, ammonia gas was injected in concentrations of 0.25%, 0.5%, and 1%, and 48 hours later, a sample was collected from each repetition in an entirely randomized design, and bacterial isolation was performed. All treatments, including positive and negative controls, were tested in quadruplicate and the parameters temperature, humidity, pH and water activity were evaluated. In the 0.5% and 1% treated samples the pathogen was not isolated, while in the 0.25% concentration one of the four samples tested was positive. The study reveals that ammonia gas is efficient in killing Salmonella Heidelberg in poultry litter at concentrations of 0.5 % or more within a 48-hour period and that the litter treated with ammonia gas increases its pH and water activity.
