ReviewIs it time to abandon glucose control in critically ill adult patients?
To summarize the advances in literature that support the best current practices regarding glucose control in the critically ill. ⋯ A 'personalized' approach to glycemic control in the critically ill, with recognition of preadmission glycemia, is supported by an emerging literature and is suitable for testing in future interventional trials.

Although vitamin C is essentially a nontoxic vitamin; however, it is important to be aware regarding the safety of high doses before the wide clinical use. ⋯ Data regarding the safety of high doses of vitamin C are scant. Until more data become available, caution should be applied in the use of high doses of vitamin C in patients with hemochromatosis, glucose-6-phosphate dehydrogenase deficiency, renal dysfunction, kidney stone, oxaluria, and pediatrics.

This review provides an update of recently conducted studies and randomized controlled trials evaluating prokinetic drugs. ⋯ It may not be feasible to establish superiority of a prokinetic drug within a randomized controlled trial with a patient-centered event as the primary outcome. The use of metoclopramide and erythromycin as prokinetic drugs is based on observations from trials measuring surrogate physiological outcomes. Randomized controlled trials of alternative drug regimens and novel prokinetic drugs have recently been completed and results outlined.

Stress ulcer prophylaxis in critically-ill patients has been a subject of extensive research, with multiple clinical trials attempting to study the best method of stress ulcer prophylaxis with the least adverse effects. Until recently, pharmacologic prophylaxis has prevailed as the primary choice for the prevention of stress ulcers but recent clinical studies have attempted to evaluate the role of enteral nutrition in stress ulcer prophylaxis. ⋯ The results of multiple recent clinical studies call for re-evaluation of the routine use of PPIs in critically ill patients who tolerates enteral nutrition in the ICU. Despite the promising preliminary results, definitive recommendations need larger clinical trials that are powered to evaluate any added benefits of using PPI in critically ill patients who tolerate enteral nutrition given the low incidence of CIGB in the current era.

ReviewMechanical circulatory support devices in cardiogenic shock and acute heart failure: current evidence.
The main purpose of this review is to highlight and summarize recently published studies on the usage of short-term mechanical circulatory support devices for treatment of cardiogenic shock. Importantly, this review will focus on percutaneously implanted devices. ⋯ Randomized, controlled trials are utterly needed to guide treatment with mechanical circulatory support for patients with cardiogenic shock. Importantly, such trials should focus patient selection criteria.
