In patients with acute respiratory distress syndrome (ARDS), the use of assisted mechanical ventilation is a subject of debate. Assisted ventilation has benefits over controlled ventilation, such as preserved diaphragm function and improved oxygenation. Therefore, higher level of "patient control" of ventilator assist may be preferable in ARDS. However, assisted modes may also increase the risk of high tidal volumes and lung-distending pressures. The current study aims to quantify how differences in freedom to control the ventilator affect lung-protective ventilation, breathing pattern variability, and patient-ventilator interaction. ⋯ In patients with mild-to-moderate ARDS, increasing freedom to control the ventilator maintains lung-protective ventilation in terms of tidal volume and lung-distending pressure, but it improves patient-ventilator interaction and preserves respiratory variability.

Review Case Reports
Lower urinary tract dysfunction in the neurological patient: clinical assessment and management.
Lower urinary tract (LUT) dysfunction is a common sequela of neurological disease, resulting in symptoms that have a pronounced effect on quality of life. The site and nature of the neurological lesion affect the pattern of dysfunction. The risk of developing upper urinary tract damage and renal failure is much lower in patients with slowly progressive non-traumatic neurological disorders than in those with spinal cord injury or spina bifida; this difference in morbidity is taken into account in the development of appropriate management algorithms. ⋯ Intradetrusor injections of onabotulinumtoxinA have transformed the management of neurogenic detrusor overactivity. Neuromodulation offers promise for managing both storage and voiding dysfunction. An individualised, patient-tailored approach is required for the management of LUT dysfunction associated with neurological disorders.

In Germany approximately 3000 body organs are transplanted annually. In general, all artificially ventilated patients with diagnosed brain death are potential organ donors. All German hospitals are obliged to report potential organ donors and be actively involved in the organ donation process. ⋯ Brain death is associated with complex pathophysiological changes in cardiopulmonary function as well as fluid, electrolyte and metabolic homeostasis. In the case of diagnosed brain death and with permission for organ donation, a precise organ-protective therapy is initiated, essentially focussing on optimal organ perfusion and oxygenation. The quality of organ protection has a direct influence on the outcome of transplantation.

Boxer's fractures are common hand injuries, but their management varies greatly. Two years ago, a boxer's fracture care pathway was developed for use in the Royal London Hospital emergency department to standardise management. ⋯ The evaluation examined the functional outcomes of patients with boxer's fractures with 50° or less palmar angulation who were discharged with no follow up. Findings show that most returned to work immediately and had good functional outcomes, which suggests that the pathway is safe for uncomplicated fractures with 50° or less palmar angulation.

Overactivity (activity engagement that significantly exacerbates pain) is a common term in the chronic pain literature. Overactivity is accepted clinically as a behaviour that adversely affects an individual's daily functioning and is the target of one of the most widely endorsed pain management strategies among health professionals (ie, activity pacing). Little research, however, has investigated links between overactivity behaviour and indicators of patient functioning, and activity pacing has not been evaluated as a stand-alone treatment specifically for individuals with chronic pain who are habitually overactive. ⋯ Some participants who were followed up 3 to 6 months after a pain management program were able to learn pacing strategies and enact behaviour change with health professional support; however, the majority reported difficulties changing their behaviour after treatment. It is suggested that provision of pacing education, alone, to chronic pain patients who engage in overactivity behaviour may not be effective in eliciting behavioural change. Key factors that participants believed to contribute to the development and maintenance of their overactive behaviour in this study should be considered in future clinical approaches and empirical investigations.
