Hydroxychloroquine (HCQ) has been used for the treatment of novel coronavirus disease cases. However, evidence of efficacy remains limited, and adverse events can be associated with its use. Here, we report a case of a patient with severe COVID-19 who, after being administered HCQ, exhibited a 10-fold increase in serum levels of transaminases, followed by a rapid decrease after HCQ was withdrawn. Considering the significantly increased use of HCQ during the COVID-19 pandemic, this case alerts us to the potential for HCQ to be associated with hepatotoxicity and the need to monitor liver function during HCQ therapy.

BackgroundFew data exist on regional systems of care for the treatment of ST‐segment–elevation myocardial infarction (STEMI) in developing countries. Our objective was to describe temporal trends in 30‐day mortality and identify predictors of mortality among STEMI patients enrolled in a prospective registry in Brazil.Methods and ResultsFrom January 2011 to June 2013, 520 patients who received initial STEMI care at 23 nonspecialized public health units or hospitals, some of whom were transferred to a public cardiology referral center, were identified through a regional STEMI network supported by telemedicine and the local prehospital emergency medical service. We stratified patients into five 6‐month periods based on presentation date. Mean age (±SD) of patients was 62.0 (±12.2) years, and 55.6% were men. The mean Global Registry of Acute Coronary Events (GRACE) score was 145 (±34). Overall mortality at 30 days was 15.0%. Use of dual antiplatelet therapy and statins increased significantly from baseline (January 2011) to period 5 (June 2013): 61.8% to 93.6% (P<0.001) and 60.4% to 79.7% (P<0.001), respectively. Rates of primary reperfusion also increased (29.1%–53.8%; P<0.001), and more patients were transferred to the referral center (44.7%–76.3%; P=0.001). Thirty‐day mortality rates decreased from 19.8% to 5.1% (P<0.001). In multivariable analysis, factors independently associated with 30‐day mortality were higher GRACE score, history of previous stroke, lack of transfer to the referral center, and lack of use of optimized medical therapy.ConclusionsImplementation of a regional STEMI system was associated with lower mortality and higher use of evidence‐based therapies.

objective: To identify the proportion of emergency physicians certified in immersion courses (ACLS -Advanced Cardiac Life Support and ATLS -Advanced Trauma Life Support) correlating the variables of age, gender, medical specialty, academic title, and type of hospital with the level of theoretical knowledge on the care of Cardiac Arrest (CA) victims. Methods:Emergency physicians from public and private hospitals of the city of Salvador, State of Bahia -Brazil, were consecutively evaluated from November, 2003 to July, 2004. They volunteered to participate in the study, and responded to a questionnaire consisting of information on the following variables of interest: professional profile, participation or not in ACLS and ATLS immersion courses, and cognitive assessment with 22 objective questions on Cardiopulmonary Resuscitation (CPR). A score of correct answers was calculated for each participant, and then designated as score variable. This questionnaire was validated based on the result of the score obtained by ACLS course instructors in Salvador, BA. Results:Of the 305 physicians who responded to the questionnaire, 83 (27.2%) had attended the ACLS course and had a mean score variable of 14.9+3.0 compared with the 215 physicians (70.5%) who had not attended the course and whose mean was 10.5+ 3.5 (p=0.0001). The mean score of the 65 cardiologists (21.5%) was 14.1+3.3 compared with the mean of 9.7+3.7(p=0.0001) of the 238 physicians (78.5%) from other specialties. No difference was observed in the mean scores between physicians who had attended the ATLS course or not (p=0.67). Conclusion:In the sample studied, theoretical knowledge on CPR was higher among physicians who had attended the ACLS course, as opposed to those who had attended the ATLS course. Cardiologists who had attended the ACLS demonstrated a higher theoretical knowledge on the care of CA patients when compared to physicians from other specialties taken as whole -Internal Medicine, Surgery, and Orthopedics.
Objective ICU severity scores such as the Sequential Organ Failure Assessment (SOFA) determine neurologic dysfunction based on the Glasgow Coma Scale, a tool that may be limited in a critically ill population. It remains unknown whether alternative methods to assess for neurologic dysfunction, such as FOUR and RASS, are superior. This study aimed to determine the predictive performance of a modified SOFA tool in a large Brazilian ICU cohort. Design Prospective cohort single center study.
Evaluate host and pathogen factors associated with mortality in those with hospital acquired infections (HAI) in a tertiary intensive care unit in Brazil. Methods: Observational and analytical cohort single center study in a general intensive care unit (ICU) in Northeastern Brazil between January 2016 and August 2018, including those over 18 years of age admitted to the ICU found to have a HAI. Results: A total of 165 patients were included, with a mean age of 72 years and male predominance (53.3%) and observed mortality of 46%. Mortality in those with HAI was significantly associated with older age, increased ICU length of stay and readmission to the ICU in univariate analysis. Multivariate analysis revealed that development of septic shock and obtundation during ICU admission was significantly associated with an increased risk of death (OR: 6.94, 95% CI 1.23-39.27, OR: 2.48, 95% CI 1.17-5.29, respectively). A trend towards mortality risk was noted in those with increased age and prior cardiovascular disease. Surprisingly, mortality risk was independent of site of infection, type of pathogen and antibiotic resistance. Furthermore, having more than one HAI over the course of the ICU admission did not impact mortality. Conclusion: Risk of death in those with HAI is associated with obtundation and septic shock, in addition to vasopressor use. Host factors, rather than pathogen-specific characteristics or infecting site, impact risk of death related to HAI in the ICU.
