Continuous intravenous (IV) infusion bumetanide has been associated with severe myalgia in case reports, and the package labeling lists a reported incidence of 0.2% for severe myalgia. The primary objective of this study was to quantify the incidence of bumetanide infusion-induced severe myalgia in patients with acute heart failure (AHF). Secondary objectives were to assess a dose-response relationship between bumetanide infusion rate and occurrence of myalgia and to investigate potential risk factors associated with bumetanide-induced myalgia. ⋯ The incidence of severe myalgia in patients with AHF receiving bumetanide infusion was 5.8%, 29-fold higher than incidence rate listed in the package labeling. Patients receiving infusion rates > 1 mg/hour were 4-fold more likely to experience bumetanide-induced severe myalgia than those receiving rates ≤ 1 mg/hour.

Enoxaparin is a widely used anticoagulant to prevent venous thromboembolism (VTE). A fixed dose is recommended for VTE prophylaxis. However, fixed prophylactic doses of enoxaparin in low-weight patients may be close to the weight-based dosing recommended for VTE treatment. ⋯ A lower dose of enoxaparin may be reasonable in low-weight patients for VTE prophylaxis. There appears to be no safety concerns with reduced enoxaparin dosing in low-weight patients. More robust data are needed to confirm these findings.

Oral azithromycin (AZM) has been shown to reduce airway inflammation and disrupt biofilm formation. However, chronic AZM therapy may result in QT interval (QTc) prolongation. ⋯ An association between chronic AZM therapy and longer QTc intervals or significant QTc prolongation was not shown.

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.
