Over the past two decades,the USA has witnessed a steep rise in the incidence of acute cholecystitis(AC),[1]even among children,[2]with over 200,000 cases annually.[3]Patients with AC often present to the emergency department(Ed)experiencing severe distress,with most describing their pain level as“intolerable.”[4]Furthermore,there is usually a considerable delay before surgery,with a median time from diagnosis of AC to surgery of 28.5 h,[5]and a substantial percentage of patients wait as long as 10 d.[6]Prolonged delays before surgery lead to increased opioid use,which is associated with extended hospital stays and higher rates of readmission after cholecystectomy.[7]Furthermore,opioids can lead to vomiting,respiratory depression,delirium,and ultimately addiction.[8]We propose a novel regional anesthesia technique for managing AC:right phrenic nerve *** method could offer improved pain control and a more favorable risk profile in selected patients when compared to current Ed practices.

Laparoscopic hepatectomy for the treatment of hepatocellular carcinoma(HCC)has been shown to have superior short-term and comparable long-term outcomes compared with open hepatectomy in experienced centres(1).Short-term advantages include small incisions,reduced post-operative pain,faster recovery,reduced blood loss and lower risk of complications(2).However,the loss of tactile sensation makes it challenging to accurately locate lesions and define tumour margins.

Recently there have been exciting research advances in neuroprotective therapies for ischemic stroke. In the past, the search for neu- roprotective agents has been fraught with failure at the clinical trials stage due to numerous factors, including subject heterogeneity and improper therapeutic windows （Tymianski, 2017）. Moreover, it is becoming clearer that the complex and evolving pathobiology of stroke requires multimodal therapeutic approaches capable of modulating the numerous axes that contribute to ischemia/reperfusion damage, rather than targeting a single axis （bernstock et al., 2018a）. With the success of recent endovascular thrombectomy （EVT） trials, it has been suggested that clinical trials of EVT with adjunct neuroprotection can overcome past difficulties and maximize the effect size by using imaging to reduce patient heterogeneity （i. e., selecting those with large vessel occlusions, small ischemic cores, and good collateral circulation）, restoring perfusion using better EVT devices, and enrolling patients in the correct therapeutic window （i.e., when they still have salvageable brain tissue）（Tymianski, 2017）. Considering the opportunity that this represents for new, better clinical trials of neuroprotective agents, the search is on for high-potential compounds that may be investigated in these future studies.
