Spontaneous breathing has been shown to induce both positive and negative effects on the function and on injury of lungs and diaphragm during critical illness; thus, monitoring of the breathing effort generated by the patient might be valuable for a better understanding of the mechanisms of disease and to set properly ventilation. The purpose of this review is to summarize the recent findings on the different techniques available to measure the patient's breathing effort, mainly during spontaneous assisted ventilation. ⋯ The development of measurement techniques and their introduction in clinical practice will allow us to understand the role of spontaneous breathing effort in the pathophysiology of lung injury and weaning failure, and how to adjust the breathing workload in an individual patient.

Management of ischemic stroke is targeted on four therapeutic objectives: limitation of neurological deficit, prevention of earyl stroke recurrence, protection against complications, and secondary prevention. Intravenous thrombolysis within 4.5h of stroke onset is the only proven therapy to improvefunctional outcome. ⋯ Subcutaneous heparin/low molecular weight heparin, mobilisation, nasogastric tube, and decompressive craniectomy may protect from venous thromboembolism, aspiration pneumonia, and malignant brain edema, respectively. Secondary prevention is guided by stroke etiology, e.g. oral anticoagulation in the presence atrial fibrillation or endarterectomy in case of sympomatic high-grade carotid stenosis.

Preoperative anemia impacts early postoperative recovery following autologous breast reconstruction.
Preoperative anemia impacts a significant portion of breast reconstruction patients, though this does not appear to affect surgical outcomes. The impact of anemia on postoperative physical and mental health, however, is unknown. This study aimed to prospectively evaluate the role of preoperative anemia in recovery after autologous reconstruction. ⋯ Though preoperative anemia may not impact surgical outcomes, it adversely impacts the recovery of breast reconstruction patients. Subjective physical health differences were significant in early follow-up, though this did not translate to differences in mental health or satisfaction. We advocate for preoperative optimization of hemoglobin to enhance the early recovery potential of breast reconstruction patients.

Effects of Levosimendan on Hemodynamics, Local Cerebral Blood Flow, Neuronal Injury, and Neuroinflammation After Asphyctic Cardiac Arrest in Rats.
Despite advances in cardiac arrest treatment, high mortality and morbidity rates after successful cardiopulmonary resuscitation are still a major clinical relevant problem. The post cardiac arrest syndrome subsumes myocardial dysfunction, impaired microcirculation, systemic inflammatory response, and neurological impairment. The calcium-sensitizer levosimendan was able to improve myocardial function and initial resuscitation success after experimental cardiac arrest/cardiopulmonary resuscitation. We hypothesized that levosimendan exerts beneficial effects on cerebral blood flow, neuronal injury, neurological outcome, and inflammation 24 hours after experimental cardiac arrest/cardiopulmonary resuscitation. ⋯ Levosimendan increased cerebral blood flow after experimental cardiac arrest/cardiopulmonary resuscitation. This effect coincided with reduced neuronal injury and improved neurologic outcome. Findings seem to be independent of inflammatory effects because no effects by levosimendan on cerebral or systemic inflammation could be detected. In summary, levosimendan is a promising agent to improve neurological outcome after cardiac arrest/cardiopulmonary resuscitation.

Complex regional pain syndrome (CRPS) may develop following fractures, limb trauma, or lesions of the peripheral or central nervous system. The clinical picture consists of a triad of symptoms including autonomic, sensory, and motor dysfunction. Diagnosis is based on clinical signs and symptoms according to the Budapest criteria. ⋯ Distinct methods of physical therapy and pharmacological strategies are the mainstay of therapy. Pharmacotherapy is based on individual symptoms and includes steroids, free radical scavengers, treatment of neuropathic pain, and agents interfering with bone metabolism. In some cases invasive methods may be considered.
