Review Meta Analysis
Establishing the Therapeutic Index of Fluid Resuscitation in the Septic Patient: A Narrative Review and Meta-Analysis.
This comprehensive review comparatively evaluates the safety and benefits of parenteral fluids used in resuscitation with a focus on sepsis. It also provides a random-effects meta-analysis of studies comparing restrictive resuscitation and usual care in sepsis with the primary outcome of mortality. In the septic patient, fluid therapy remains a complex interplay between fluid compartments in the body, the integrity of the endothelial barrier, and the inflammatory tone of the patient. ⋯ Compared with isotonic saline, balanced resuscitation fluids are associated with a lower incidence of acute kidney injury and mortality. The benefits of balanced resuscitation fluids are most evident when higher volumes of fluids are used for sepsis. Clinicians should consider these pharmacotherapeutic factors when selecting a fluid, its quantity, and rate of infusion.

To compare the efficacy and safety of once-weekly and twice-weekly bortezomib therapy in patients with hematologic malignancies. ⋯ Compared with twice-weekly bortezomib, once-weekly bortezomib had a comparable ORR and a probable lower incidence of peripheral neuropathy. More clinical trials are needed to draw a conclusion regarding the difference in peripheral neuropathy between the two groups because of the insufficient evidence detected by TSA and the inconsistent results among subgroups.

The impact of vasopressin and norepinephrine discontinuation order in the recovery phase of septic shock remains controversial. This systematic review and patient-level meta-analysis were performed to determine the impact of vasopressin and norepinephrine discontinuation order on clinically significant outcomes in the recovery phase of septic shock. ⋯ Discontinuation of norepinephrine prior to vasopressin during the recovery phase of septic shock resulted in less clinically significant hypotension but no difference in mortality or lengths of stay. Larger, prospective studies evaluating the impact of relative vasopressin deficiency and norepinephrine and vasopressin discontinuation order and timing on patient-centered outcomes are needed.

Review Meta Analysis
Re-evaluating the Utility of Stress Ulcer Prophylaxis in the Critically Ill Patient: A Clinical Scenario-Based Meta-Analysis.
Because recent studies have challenged the efficacy of stress ulcer prophylaxis (SUP) in the critically ill patient, our objective was to evaluate the efficacy of SUP with proton pump inhibitors (PPIs) or histamine2 -receptor antagonists (H2 RAs) against placebo, control, no therapy, or enteral nutrition alone in critically ill adults. ⋯ This meta-analysis demonstrated that SUP use was associated with significant reductions in bleeding but not mortality. SUP should not be abandoned until large randomized trials demonstrate the futility of this intervention.

Review Meta Analysis
Low-Dose Naloxone for Prophylaxis of Postoperative Nausea and Vomiting: A Systematic Review and Meta-analysis.
To determine whether postoperative administration of low-dose intravenous naloxone decreases the incidence of postoperative nausea and vomiting (PONV) and its impact on postoperative opioid requirements and pain scores. ⋯ This pooled analysis of data suggests that low-dose naloxone plays no role in preventing PONV, while exhibiting no significant effects on postoperative opioid needs and pain scores. The reduction demonstrated in postoperative nausea did not translate into decreases in postoperative vomiting.
