The synopsis by Hines et al reports various definitions of bronchopulmonary dysplasia (BPD) (1). We agree there is a need to harmonise the definition of BPD and our definition (2) was adapted from the National Institute of Child Health and Human Development network definition by Jobe and Bancalari (3) It incorporates important aspects that have evolved over time, such as the use of high-flow nasal cannulas, and takes into account differences between clinical centres, including different target oxygen saturations...

Free fatty acids (FFAs) are important substrates for mitochondrial oxidative metabolism and ATP synthesis but also cause serious stress to various tissues, contributing to the development of metabolic diseases. CD36 is a major mediator of cellular FFA uptake. Inside the cell, saturated FFAs are able to induce the production of cytosolic and mitochondrial reactive oxygen species (ROS), which can be prevented by co-exposure to unsaturated FFAs. There are close connections between oxidative stress and organellar Ca(2+) homeostasis...

OBJECTIVES: Viral-lower respiratory tract disease is common in young children worldwide and is associated with high morbidity. Acute respiratory failure due to viral-lower respiratory tract disease necessitates PICU admission for mechanical ventilation. In critically ill patients in PICU settings, early fluid overload is common and associated with adverse outcomes such as prolonged mechanical ventilation and increased mortality. It is unclear, however, if this also applies to young children with viral-lower respiratory tract disease induced acute respiratory failure...

It has been reported in the 3 Benefits of Oxygen Saturation Targeting (BOOST-II) trials that changes in oximeter calibration software resulted in clearer separation between the oxygen saturations in the two trial target groups. A revised analysis of the published BOOST-II data does not support this conclusion.

OBJECTIVE: Tuberculosis (TB) is a devastating disease that remains a major health threat worldwide. The appearance of Mycobacterium tuberculosis strains resistance to current antibiotics is a growing problem, both in the third world and in developed countries. Completion of genomic sequencing of M. tuberculosis provides a strong foundation for subsequent identification of proteins to aid the understanding of protein function and the discovery of new drug targets or a TB vaccine. This study employed a proteomics approach to identify proteins from antibiotic resistant M...

BACKGROUND: Recently, several trials have shown that closed-loop sedation is feasible. No study has used automated sedation in extremely frail patients, such as those scheduled for transcatheter aortic valve implantation (TAVI). We developed and tested a novel automated sedation system for this kind of population and surgery. The system integrates a decision support system that detects respiratory and hemodynamic events via smart alarms, which provide pertinent/related clinical suggestions and treatment options...

BACKGROUND: Circulatory vulnerability reflected by low systemic venous oxygen saturation after surgical palliation of hypoplastic left heart syndrome predicts adverse neurologic outcome and reduced survival, and targeting venous saturation may improve outcome. We herein test the hypothesis that near-infrared spectroscopy (NIRS)-derived cerebral and somatic/renal regional saturations can predict survival. METHODS: Patient data, from a prospective Institutional Review Board-approved registry of hemodynamic measures after initial palliation of hypoplastic left heart syndrome, were analyzed with logistic and multivariable mixed regression methods to determine relationships between standard hemodynamic measures, direct and NIRS measures of saturation, and outcome...

Arterial desaturation impairs exercise performance in a dose-dependent manner. However, new theories of exercise-induced fatigue suggest that increasing rates of arterial deoxygenation augment the fatigue response during exercise. The purpose of this dissertation is to clarify if self-selected exercise intensity, while exercising at a constant rate of perceived exertion (RPE), is sensitive to alterations in the absolute arterial saturation (SPO2) and/or the rate of change in SPO2. Subjects performed constant RPE exercise for 30 min...

INTRODUCTION: The pulmonary embolism severity index (PESI) or simplified version (sPESI) are widely validated risk scores for the identification of eligible patients for outpatient treatment. Saturation is one of these criteria. For this metric, saturation of 90% or greater is assigned zero points. However, 90% saturation does not always exclude hypoxemic respiratory failure. OBJECTIVE: The aims of this study were first was to define corresponding partial arterial oxygen pressure (PaO2 ) values according to saturation in pulmonary embolism (PE) patients, and the second was to define a target saturation that can exclude hypoxemic respiratory failure and enable secure discharge of PE patients from emergency departments...

REVIEW
John C Greenwood, Clinton J Orloski
Resuscitation goals for the patient with sepsis and septic shock are to return the patient to a physiologic state that promotes adequate end-organ perfusion along with matching metabolic supply and demand. Ideal resuscitation end points should assess the adequacy of tissue oxygen delivery and oxygen consumption, and be quantifiable and reproducible. Despite years of research, a single resuscitation end point to assess adequacy of resuscitation has yet to be found. Thus, the clinician must rely on multiple end points to assess the patient's overall response to therapy...
