Review Meta AnalysisAminophylline for bradyasystolic cardiac arrest in adults.
In cardiac ischaemia, the accumulation of adenosine may lead to or exacerbate bradyasystole and diminish the effectiveness of catecholamines administered during resuscitation. Aminophylline is a competitive adenosine antagonist. Case studies suggest that aminophylline may be effective for atropine-resistant bradyasystolic arrest. ⋯ The prehospital administration of aminophylline in bradyasystolic arrest is not associated with improved return of circulation, survival to admission or survival to hospital discharge. The benefits of aminophylline administered early in resuscitative efforts are not known.

Review Meta AnalysisAirway clearance techniques for bronchiectasis.
People with non-cystic fibrosis bronchiectasis commonly experience chronic cough and sputum production and these features may be associated with progressive decline in clinical status. Airway clearance techniques (ACTs) are often prescribed to facilitate expectoration of sputum from the lungs, but the efficacy of these techniques in a stable clinical state or during an acute exacerbation of bronchiectasis is unclear. ⋯ ACTs appear to be safe for individuals (adults and children) with stable bronchiectasis, where there may be improvements in sputum expectoration, selected measures of lung function and health-related quality of life. The role of these techniques in people with an acute exacerbation of bronchiectasis is unknown. In view of the chronic nature of bronchiectasis, more data are needed to establish the clinical value of ACTs over the short and long term on patient-important outcomes, including symptoms, on physiological outcomes which may clarify the rationale for each technique and on long-term parameters that impact on disease progression in individuals with stable bronchiectasis. This is necessary in order to provide further guidance of specific ACT prescription for people with bronchiectasis. It may also be important to establish the comparative effect of different types of ACTs in people with bronchiectasis.

Review Meta AnalysisExercise training undertaken by people within 12 months of lung resection for non-small cell lung cancer.
Decreased exercise capacity and impairments in health-related quality of life (HRQoL) are common in people following lung resection for non-small cell lung cancer (NSCLC). Exercise training has been demonstrated to confer gains in exercise capacity and HRQoL for people with a range of chronic conditions, including chronic obstructive pulmonary disease and heart failure, as well as in people with cancers such as prostate and breast cancer. A programme of exercise training for people following lung resection for NSCLC may confer important gains in these outcomes. To date, evidence of its efficacy in this population is unclear. ⋯ The evidence summarised in our review suggests that exercise training may potentially increase the exercise capacity of people following lung resection for NSCLC. The findings of our systematic review should be interpreted with caution due to disparities between the studies, methodological limitations, some significant risks of bias and small sample sizes. This systematic review emphasises the need for larger RCTs..

Review Meta AnalysisExercise for improving outcomes after osteoporotic vertebral fracture.
Vertebral fractures are associated with increased morbidity (e.g., pain, reduced quality of life), and mortality. Therapeutic exercise is a non-pharmacologic conservative treatment that is often recommended for patients with vertebral fractures to reduce pain and restore functional movement. ⋯ No definitive conclusions can be made regarding the benefits of exercise for individuals with vertebral fracture. Although individual trials did report benefits for some pain, physical function and quality of life outcomes, the findings should be interpreted with caution given that findings were inconsistent and the quality of evidence was very low. The small number of trials and variability across trials limited our ability to pool outcomes or make conclusions. Evidence regarding the effects of exercise after vertebral fracture, particularly for men, is scarce. A high-quality randomized trial is needed to inform exercise prescription for individuals with vertebral fractures.

ReviewEarly versus delayed post-operative bathing or showering to prevent wound complications.
Many people undergo surgical operations during their life-time, which result in surgical wounds. After an operation the incision is closed using stiches, staples, steri-strips or an adhesive glue. Usually, towards the end of the surgical procedure and before the patient leaves the operating theatre, the surgeon covers the closed surgical wound using gauze and adhesive tape or an adhesive tape containing a pad (a wound dressing) that covers the surgical wound. There is currently no guidance about when the wound can be made wet by post-operative bathing or showering. Early bathing may encourage early mobilisation of the patient, which is good after most types of operation. Avoiding post-operative bathing or showering for two to three days may result in accumulation of sweat and dirt on the body. Conversely, early washing of the surgical wound may have an adverse effect on healing, for example by irritating or macerating the wound, and disturbing the healing environment. ⋯ There is currently no conclusive evidence available from randomised trials regarding the benefits or harms of early versus delayed post-operative showering or bathing for the prevention of wound complications, as the confidence intervals around the point estimate are wide, and, therefore, a clinically significant increase or decrease in SSI by early post-operative bathing cannot be ruled out. We recommend running further randomised controlled trials to compare early versus delayed post-operative showering or bathing.
