BACKGROUND Desflurane has adverse environmental effects, but has clinical advantages to speed emergence and return of protective airway reflexes compared with sevoflurane. We hypothesized that weaning of the inspired sevoflurane during the final 15 minutes of surgery would eliminate differences in airway reflex recovery between these agents. METHODS After obtaining IRB approval and informed consent, 40 patients undergoing elective surgery (≥1-hour) randomly received desflurane or sevoflurane. Patients swallowed 20 mL of water without drooling or coughing, and then received sedation and PONV pre-medication. Anesthesia was induced using propofol and fentanyl and maintained with desflurane or sevoflurane through a laryngeal mask airway maintaining a bispectral index of 45-50 and 50-60 during the final 15 minutes before surgery end. Cardiorespiratory variables and age-adjusted minimal alveolar concentration were recorded. The duration between anesthetic discontinuation and first appropriate response to command was measured; the laryngeal mask airway was removed. Two minutes after responding to command, patients were positioned semi-upright and attempted to swallow water. If successful swallowing was not achieved, the test was repeated every 4 minutes after each failure until successful swallowing was achieved. AEB071 cell line RESULTS Average anesthetic concentration and bispectral index was similar in patients receiving desflurane vs sevoflurane. Response times after discontinuation of anesthetics were similar. There were no differences in the recovery of swallowing ability between desflurane and sevoflurane groups. CONCLUSION Weaning of sevoflurane during the final 15 minutes of surgery eliminates clinical advantages of the more rapid return of airway reflexes with desflurane. Published 2019.

A discrete choice experiment was performed to explore patient preferences regarding outcome (overall response rate, 2-year survival rate, progression-free survival, time to response, type of adverse events, probability of adverse event-related treatment discontinuation) and process attributes (frequency and route of administration, frequency of consultations) of modern treatments for melanoma. Mean preferences of 150 patients with melanoma stage IIC–IV were highest for overall response rate (relative importance score (RIS) 26.8) and 2-year survival (RIS 21.6), followed by type of adverse events (RIS 11.7) and probability of adverse event-related treatment discontinuation (RIS 9.2). Interest in overall response rate and 2-year survival declined with increasing age, whereas process attributes gained importance. Participants who had experienced treatment with immune checkpoint inhibitors valued overall response rate more highly and worried less about the type of adverse events. In conclusion, patients with advanced melanoma consider efficacy of treatment options most important, followed by safety, but preferences vary with individual and disease-related characteristics.BACKGROUND Acquired brain injury can cause disorders of consciousness. An additive effect of cerebrolysin and amantadine has been postulated, but not systematically studied. The present study aimed to investigate this additive effect in patients with disorders of consciousness secondary to acquired brain injury. METHODS The medical records of patients diagnosed with disorders of consciousness after acquired brain injury were reviewed. The patients were categorized into 2 groups single regimen (amantadine only) and dual regimen (amantadine plus cerebrolysin). The patients' conscious states were assessed using the Coma Recovery Scale-Revised (CRS-R) before, and after 4 weeks of drug administration. RESULTS Data for a total of 84 patients were analysed. The degree of change in CRS-R and the proportion of patients in the disorders of consciousness category showing a change was higher in the dual regimen group than in the single regimen group. Analysis of patients who had initially been in a prolonged vegetative state or minimally conscious state minus before administration showed that the patients in the dual regimen group had greater increases in CRS-R scores than those in the single regimen group. CONCLUSION This study identified that an amantadine-plus-cerebrolysin regimen additively affects patients with prolonged disorders of consciousness. A future controlled trial is needed to investigate the efficacy of each regimen in patients with prolonged disorders of consciousness secondary to acquired brain injury, particularly for patients who have remained in a prolonged vegetative state after acquired brain injury.The spreading hypothesis of neurodegeneration assumes an expansion of neural pathologies along existing neural pathways. Multimodal neuroimaging studies have demonstrated distinct topographic patterns of cerebral pathologies in neurodegeneration. For Parkinson's disease the hypothesis so far rests largely on histopathological evidence of α-synuclein spreading in a characteristic pattern and progressive nigrostriatal dopamine depletion. Functional consequences of nigrostriatal dysfunction on cortical activity remain to be elucidated. Our goal was to investigate multimodal imaging correlates of degenerative processes in Parkinson's disease by assessing dopamine depletion and its potential effect on striatocortical connectivity networks and cortical metabolism in relation to parkinsonian symptoms. We combined 18F-DOPA-PET, 18F-fluorodeoxyglucose (FDG)-PET and resting state functional MRI to multimodally characterize network alterations in Parkinson's disease. Forty-two patients with mild-to-moderate stage Parkine for network-dependent degeneration in Parkinson's disease by outlining the impact of functional nigrostriatal pathway impairment on striatocortical functional connectivity networks and cortical metabolism. © The Author(s) (2020).
