Review Meta AnalysisDiastolic dysfunction and mortality in septic patients: a systematic review and meta-analysis.
Myocardial dysfunction may contribute to the haemodynamic instability which accompanies sepsis, and may result in circulatory failure. There is no association between systolic dysfunction (SD) and mortality in septic patients and there is conflicting evidence regarding the effects of diastolic dysfunction (DD) on mortality in septic patients. ⋯ Diastolic dysfunction is common in septic patients and it is associated with mortality. Systolic dysfunction is less common and is not associated with mortality in this group of patients.

ReviewUnderstanding and Reducing Disability in Older Adults Following Critical Illness.
To review how disability can develop in older adults with critical illness and to explore ways to reduce long-term disability following critical illness. ⋯ Older adults who survive critical illness have physical and cognitive declines resulting in disability at greater rates than hospitalized, noncritically ill and community dwelling older adults. Interventions derived from widely available geriatric care models in use outside of the ICU, which address modifiable risk factors including immobility and delirium, are associated with improved functional and cognitive outcomes and can be used to complement ICU-focused models such as the ABCDEs.

Effects of weight loss on airway responsiveness in obese asthmatics: Does weight loss lead to reversibility of asthma?
The growing epidemics of obesity and asthma are major public health concerns. Although asthma-obesity links are widely studied, the effects of weight loss on asthma severity measured by airway hyperresponsiveness (AHR) have received limited attention. The main study objective was to examine whether weight reduction reduces asthma severity in obese adults with asthma. ⋯ Weight loss in obese adults with asthma can improve asthma severity, AHR, asthma control, lung function, and quality of life. These findings support the need to actively pursue healthy weight-loss measures in this population.

Because anesthetic machines have become more complex and more expensive, they have become less suitable for use in the many isolated hospitals in the poorest countries in the world. In these situations, they are frequently unable to function at all because of interruptions in the supply of oxygen or electricity and the absence of skilled technicians for maintenance and servicing. Despite these disadvantages, these machines are still delivered in large numbers, thereby expending precious resources without any benefit to patients. ⋯ Additional economies are achieved by completely eliminating spillage of oxygen from the breathing system and by recycling the driving gas into the breathing system to increase the Fraction of Inspired Oxygen (FIO2) at no extra cost. Savings also are accrued when using the drawover breathing system as the need for nitrous oxide, compressed air, and soda lime are eliminated. The Glostavent enables the administration of safe anesthesia to be continued when standard machines are unable to function and can do so with minimal harm to the environment.

ReviewOptimal technique for deep breathing exercises after cardiac surgery.
Cardiac surgery patients often develop a restrictive pulmonary impairment and gas exchange abnormalities in the early postoperative period. Chest physiotherapy is routinely prescribed in order to reduce or prevent these complications. Besides early mobilization, positioning and shoulder girdle exercises, various breathing exercises have been implemented as a major component of postoperative care. ⋯ Arbitrary instructions are given, and recommendations on performance and duration vary between hospitals. Deep breathing exercises are a major part of this therapy, but scientific evidence for the efficacy has been lacking until recently, and there is a lack of trials describing how postoperative breathing exercises actually should be performed. The purpose of this review is to provide a brief overview of postoperative breathing exercises for patients undergoing cardiac surgery via sternotomy, and to discuss and suggest an optimal technique for the performance of deep breathing exercises.
