Diagnosis of acute mesenteric ischemia in the early stages is now possible with modern computed tomography (CT), using intravenous contrast enhancement and imaging in the arterial and/or portal venous phase. The availability of CT around the clock means that more patients with acute mesenteric ischemia may be treated with urgent intestinal revascularization. ⋯ Intestinal revascularization in patients with arterial occlusive mesenteric ischemia reduces bowel morbidity and mortality. Observational studies report that both endovascular and open vascular therapy options are effective, but endovascular technique may be preferred in these often elderly and fragile patients.

ReviewReversal of the novel oral anticoagulants dabigatran, rivoraxaban, and apixaban.
We summarize the available data related to reversing the anticoagulant effect of the oral direct thrombin and factor Xa inhibitors and provide our opinion on treating patients presenting with severe and life-threatening hemorrhage related to these agents. ⋯ In the absence of evidence in bleeding patients, animal models and ex-vivo studies suggest administration of coagulant factors in the form of hemostatic agents may be of benefit in reversing the effect of direct thrombin and factor Xa inhibitors. Specific reversal agents and clinical data in patients with hemorrhage remain an unmet need.

Although detailed practice parameters have been developed to help guide physicians in brain death determination, guidelines based on these parameters widely vary. The recent case of Jahi McMath not only highlights social misconceptions but also serves as a call to action to decrease medical variability and confusion regarding brain death determination. This review discusses common sources of variations in brain death determination - we divide these sources into before, during, and after brain death declaration. ⋯ Diagnosing brain death is confusing because of numerous variations in practice, but this variation can be improved. Improved and standardized physician training can help create a formal certification process for examiners and help create uniformity in brain death determination. National standards will also help decrease variability of practice.

ReviewLiver transplantation in the context of organ shortage: toward extension and restriction of indications considering recent clinical data and ethical framework.
The scarcity of liver grafts requires to optimize the results of transplantation. Extensions and alternatives of liver transplantation have to be regularly evaluated. ⋯ Before implementation of these potential changes into decisional algorithms for listing and organ allocation, their consequences, either for patient's individual benefit or for global transplant outcomes, should be closely evaluated using objective long-term end points and taking into account the ethical recommendations for organ transplantation.

ReviewBlood pressure management in acute intracerebral hemorrhage: current evidence and ongoing controversies.
Spontaneous intracerebral hemorrhage (ICH) is associated with high rates of morbidity and mortality. Although treatment options are limited, a potential acute medical intervention is blood pressure (BP) reduction. The review will summarize the current evidence and remaining knowledge gaps with respect to acute BP management in acute ICH. ⋯ Recent trials have shown that BP lowering (<140 mmHg systolic) is well tolerated and may improve functional outcomes. Ongoing trials will provide insight into the overall benefit of early aggressive BP reduction in acute ICH.
