Resuscitation fluid practices in Brazilian intensive care units: a secondary analysis of Fluid-TRIPS.

Objective: To describe fluid resuscitation practices in Brazilian intensive care units and to compare them with those of other countries participating in the Fluid-TRIPS.

Methods: This was a prospective, international, cross-sectional, observational study in a convenience sample of intensive care units in 27 countries (including Brazil) using the Fluid-TRIPS database compiled in 2014. We described the patterns of fluid resuscitation use in Brazil compared with those in other countries and identified the factors associated with fluid choice.

Effect of Lung Recruitment and Titrated Positive End-Expiratory Pressure (PEEP) vs Low PEEP on Mortality in Patients With Acute Respiratory Distress Syndrome: A Randomized Clinical Trial.

Importance: The effects of recruitment maneuvers and positive end-expiratory pressure (PEEP) titration on clinical outcomes in patients with acute respiratory distress syndrome (ARDS) remain uncertain.

Objective: To determine if lung recruitment associated with PEEP titration according to the best respiratory-system compliance decreases 28-day mortality of patients with moderate to severe ARDS compared with a conventional low-PEEP strategy.

Design, Setting, And Participants: Multicenter, randomized trial conducted at 120 intensive care units (ICUs) from 9 countries from November 17, 2011, through April 25, 2017, enrolling adults with moderate to severe ARDS.

Effect of lycopene on doxorubicin-induced cardiotoxicity: an echocardiographic, histological and morphometrical assessment.

Doxorubicin is an excellent chemotherapeutic agent utilized for several types of cancer but the irreversible doxorubicin-induced cardiac damage is the major limitation for its use. Oxidative stress seems to be associated with some phase of the toxicity mechanism process. To determine if lycopene protects against doxorubicin-induced cardiotoxicity, male Wistar rats were randomly assigned either to control, lycopene, doxorubicin or doxorubicin + lycopene groups.

Myxedema ascites with elevated serum CA 125 concentration.

We report a case of myxedema ascites and markedly elevated serum CA 125 concentration. The cause of ascites and elevated tumor markers in hypothyroidism remains unknown. Diagnosis was characterized by no evidence of malignancy seen by transvaginal ultrasonography or abdominal computed tomography and ascites resolution with serum CA 125 normalization after adequate hormonal treatment.

[Tropical pyomyositis: atypical presentations].

Tropical pyomyositis is a primary infection of the skeletal muscles, that occurs mainly in tropical countries. At onset its manifestation is nonspecific, thereby hindering the diagnostic. The natural history of this disease is commonly benign, with rare complications.

Mortality decline after implementation of standard protocols for treating patients with acute myocardial infarction.

Objective: To compare 30-day mortality in patients receiving different types of medication from 1992 to 1997, when no consensual treatment for acute myocardial infarction was available, versus 30-day mortality in patients being treated between 2000 and 2002 after standardization of that treatment was obtained in our service.

Methods: In the first and second study periods, 172 and 143 patients, respectively, admitted with the diagnosis of acute myocardial infarction were retrospectively assessed. Their diagnoses were confirmed, and the following statistical tests were performed: the chi-square test for comparing proportions and the Student t test and the Mann-Whitney test for comparing the means or medians.
