1. Autonomic heart rate modulation in patients with coronavirus disease 2019 in mechanical ventilation
SUMMARY BACKGROUND: Patients with coronavirus disease 2019 on automatic mechanical ventilation have greater heart rate modulation with greater parasympathetic modulation. OBJECTIVE: To analyze the autonomic modulation of heart rate in critically ill patients with coronavirus disease 2019 on invasive mechanical ventilation. METHODS: A cross-section study w

2. Cardiovascular involvement in COVID-19: not to be missed
Abstract In December 2019, a striking appearance of new cases of viral pneumonia in Wuhan led to the detection of a novel coronavirus (SARS-CoV2). By analyzing patients with severe manifestations, it became apparent that 20 to 35% of patients who died had preexisting cardiovascular disease. This finding warrants the important need to discuss the influence of

3. Inflammatory lung injury in rabbits: effects of high-frequency oscillatory ventilation in the prone position
RESUMO Objetivo: Comparar os efeitos das posições prona e supina durante ventilação oscilatória de alta frequência (VOAF) sobre oxigenação e inflamação pulmonar, lesão histológica e estresse oxidativo em um modelo de lesão pulmonar aguda (LPA) em coelhos. Métodos: Trinta coelhos Norfolk machos brancos foram submetidos à LPA por meio de lavag

4. Active surveillance to determine the impact of methicillin resistance on mortality in patients with bacteremia and influences of the use of antibiotics on the development of MRSA infection
Introduction Methicillin-resistant Staphylococcus aureus (MRSA) is among the most important pathogens of nosocomial infections, mainly in intensive care units (ICUs), and accounts for 40-60% of all healthcare-associated S. aureus infections. We evaluated the incidence of nosocomial infection by S. aureus, identified the risk factors for MRSA infection, and

5. Efeitos fisiológicos da ventilação de alta frequência usando ventilador convencional em um modelo experimental de insuficiência respiratória grave / Physiological effects of high frequency ventilation with conventional ventilator in an experimental model of severe respiratory failure
Introduction: Acute respiratory distress syndrome (ARDS) has a high incidence and mortality between critical ill patients. The mechanical ventilation is the most important support for these patients with ARDS. However, until now there is an important debate about how is the best ventilatory strategy to use, because the mechanical ventilation if not well set

6. Clinical and microbiological characterization of pneumonia in mechanically ventilated patients
OBJECTIVE: To characterize mechanical ventilation-associated pneumonia (MVAP). METHOD: This is an observational descriptive study to characterize MVAP in 61 ventilated patients admitted in the intensive care units of the Hermanos Ameijeiras hospital during 2011. This study also aimed to isolate the bacteria causing MVAP and characterize their resistance to a

7. Toxicidade da deltametrina (formulação Butox CE25) nas respostas cardio-respiratórias da tilápia-do-Nilo (Oreochromis niloticus)
Deltamethrin is a synthetic pyrethroid pesticide, type II, considered of low persistence in the environment and widely utilized in agriculture and aquaculture to control plagues and aquatic parasites respectivamently. In spite of it low toxicity in mammals, this pesticide can be extremely toxic for fish. In this study, we evaluate the effects of a sub-lethal

8. A scanographic assessment of alveolar recruitment and overinflation during high frequence ventilation : preliminary results in three patients
BACKGROUND AND OBJECTIVES: High-frequency ventilation (HFV) may offer an attractive alternative to conventional strategies in the ventilation of the acute respiratory distress syndrome (ARDS) or acute lung injury (ALI) because it can minimize lung injury. Maintaining ventilation between lower and upper inflection points, it can warrant alveolar recruitment w

Objective: To describe epidemiologic frequency and characteristics of intra-hospital neonatal deaths associated to perinatal asphyxia in the country side of Alagoas state in 2009. Method: Prospective cross-seccional study with weekly active search for medical records of mothers and their newborn infants who died before 28 days of age from January 1st to Dece

10. Acute application of bilevel positive airway pressure influences the cardiac autonomic nervous system
INTRODUCTION: Noninvasive positive pressure has been used to treat several diseases. However, the physiological response of the cardiac autonomic system during bilevel positive airway pressure (Bilevel) remains unclear. OBJECTIVE: The aim of this study was to evaluate the heart rate variability (HRV) during Bilevel in young healthy subjects. METHODS: Twenty

11. Concentrações de mediadores inflamatórios em crianças com idade inferior a três meses e infecção do trato respiratório inferior pelo vírus sincicial respiratório / Concentrations of inflammatory mediators in children less than three months of age with respiratory syncytial virus lower respiratory tract infection
INTRODUCTION: The high frequency and morbimortality of respiratory syncytial virus (RSV) lower respiratory tract infections (LRTI) in children, besides the lack of studies in Brazil that evolutionally correlate the inflammatory response in respiratory epithelium and in peripheral blood with RSV respiratory disease severity, have stimulated this research.

12. Utilization of the lower inflection point of the pressure-volume curve results in protective conventional ventilation comparable to high frequency oscillatory ventilation in an animal model of acute respiratory distress syndrome
INTRODUCTION: Studies comparing high frequency oscillatory and conventional ventilation in acute respiratory distress syndrome have used low values of positive end-expiratory pressure and identified a need for better recruitment and pulmonary stability with high frequency. OBJECTIVE: To compare conventional and high frequency ventilation using the lower infl
