Randomized Controlled Trial
One-year outcome of the sevoflurane in acute myocardial infarction randomized trial.
Sevoflurane is an inhalation anesthetic that has cardioprotective effects. There is limited information regarding its use outside of the operating room and its potential protective effect for patients presenting with myocardial infarction. ⋯ In this study, we did not find an effect of sevoflurane on left ventricular function or myocardial injury at one year post STEMI. This trial was registered at www.clinicaltrials.gov ; identifier: NCT00971607.

Case ReportsQuinidine in the treatment of KCNT1 positive epilepsies.
We report 2 patients with drug-resistant epilepsy caused by KCNT1 mutations who were treated with quinidine. Both mutations manifested gain of function in vitro, showing increased current that was reduced by quinidine. ⋯ The other, who had a novel phenotype, with severe nocturnal focal and secondary generalized seizures starting in early childhood with developmental regression, did not improve. Although quinidine represents an encouraging opportunity for therapeutic benefits, our experience suggests caution in its application and supports the need to identify more targeted drugs for KCNT1 epilepsies.

ReviewEEG as an Indicator of Cerebral Functioning in Postanoxic Coma.
Postanoxic coma after cardiac arrest is one of the most serious acute cerebral conditions and a frequent cause of admission to critical care units. Given substantial improvement of outcome over the recent years, a reliable and timely assessment of clinical evolution and prognosis is essential in this context, but may be challenging. In addition to the classic neurologic examination, EEG is increasingly emerging as an important tool to assess cerebral functions noninvasively. ⋯ Here, the most frequently encountered EEG patterns in postanoxic coma are summarized and their relations with outcome prediction are discussed. This article also addresses the influence of targeted temperature management on brain signals and the implication of the evolution of EEG patterns over time. Finally, the article ends with a view of the future prospects for EEG in postanoxic management and prognostication.

Biomarker Profiles in Asthma with High vs. Low Airway Reversibility and Poor Disease Control.
High bronchodilator reversibility in adult asthma is associated with distinct clinical characteristics. This analysis compares lung function, biomarker profiles, and disease control in patients with high reversibility (HR) and low reversibility (LR) asthma. ⋯ HR is a physiologic indicator of reduced lung function and is more often associated with elevations in Th2 biomarkers than LR in moderate to severe asthma. However, the majority of patients with HR and LR asthma in this analysis had a Th2-low biomarker profile. Moreover, a Th2-high biomarker profile was not associated with worse disease control.

Randomized Controlled Trial Observational Study
The discriminatory value of cardiorespiratory interactions in distinguishing awake from anaesthetised states: a randomised observational study.
Depth of anaesthesia monitors usually analyse cerebral function with or without other physiological signals; non-invasive monitoring of the measured cardiorespiratory signals alone would offer a simple, practical alternative. We aimed to investigate whether such signals, analysed with novel, non-linear dynamic methods, would distinguish between the awake and anaesthetised states. We recorded ECG, respiration, skin temperature, pulse and skin conductivity before and during general anaesthesia in 27 subjects in good cardiovascular health, randomly allocated to receive propofol or sevoflurane. ⋯ The phase coherence was reduced by both agents at frequencies below 0.145 Hz (p < 0.05), whereas the cardiorespiratory synchronisation time was increased (p < 0.05). A classification analysis based on an optimal set of discriminatory parameters distinguished with 95% success between the awake and anaesthetised states. We suggest that these results can contribute to the design of new monitors of anaesthetic depth based on cardiovascular signals alone.
