Early Treatment With Metformin in a Mice Model of Complex Regional Pain Syndrome Reduces Pain and Edema.
Metformin, an adenosine monophosphate (AMP)-activated protein kinase activator, as well as a common drug for type 2 diabetes, has previously been shown to decrease mechanical allodynia in mice with neuropathic pain. The objective of this study is to determine if treatment with metformin during the first 3 weeks after fracture would produce a long-term decrease in mechanical allodynia and improve a complex behavioral task (burrowing) in a mouse tibia fracture model with signs of complex regional pain syndrome. ⋯ The important finding of this study was that early treatment with metformin reduces mechanical allodynia in a complex regional pain syndrome model in mice. Our findings suggest that AMP-activated protein kinase activators may be a viable therapeutic target for the treatment of pain associated with complex regional pain syndrome.

Randomized Controlled Trial Multicenter StudyIntrathecal Drug Delivery Systems for Cancer Pain: An Analysis of a Prospective, Multicenter Product Surveillance Registry.
The safety and efficacy of intrathecal drug delivery systems (IDDSs) for the treatment of cancer-related pain have been demonstrated in randomized controlled clinical trials (RCTs). Despite positive evidence for this therapy, IDDS remains underutilized to treat cancer pain. Real-world registry data augment existing safety and effectiveness data and are presented here to broaden awareness of this therapeutic option, needed for adequate cancer-related pain treatment, and as a viable tool addressing concerns with systemic opioid use. ⋯ Adequate and improved pain control in patients with cancer, even in advanced stages, with concurrent quality of life maintenance is attainable. Results from this large-scale, multicenter, single-group cohort supplement existing RCT data that support IDDS as a safe and effective therapeutic option with a positive benefit-risk ratio in the treatment of cancer pain.

Observational StudyPrevalence of Isoelectric Electroencephalography Events in Infants and Young Children Undergoing General Anesthesia.
In infants and young children, anesthetic dosing is based on population pharmacokinetics and patient hemodynamics not on patient-specific brain activity. Electroencephalography (EEG) provides insight into brain activity during anesthesia. The primary goal of this prospective observational pilot study was to assess the prevalence of isoelectric EEG events-a sign of deep anesthesia-in infants and young children undergoing general anesthesia using sevoflurane or propofol infusion for maintenance. ⋯ Isoelectric EEG events were common in infants and young children undergoing sevoflurane or propofol anesthesia. Although the clinical significance of these events remains uncertain, they suggest that dosing based on population pharmacokinetics and patient hemodynamics is often associated with unnecessary deep anesthesia during surgical procedures.

Multicenter StudyRetrospective Analysis of Obstetric Intensive Care Unit Admissions Reveals Differences in Etiology for Admission Based on Mode of Conception.
The use of in vitro fertilization is increasing. The incidence of adverse outcomes is greater for women who undergo in vitro fertilization, potentially leading to intensive care unit admission. This study aimed to assess the etiology and course of intensive care unit admission in women who underwent in vitro fertilization compared to those who did not, with specific focus on intensive care unit admission due to postpartum hemorrhage. ⋯ Among patients admitted to the intensive care unit, patients with different modes of conception had dissimilar etiologies for intensive care unit admission with intensive care unit admission due to hemorrhage greater in those with in vitro fertilization. Higher rates of multiple gestation pregnancies may explain this difference. Differences in pregnancies conceived via in vitro fertilization versus without in vitro fertilization may affect the obstetric intensive care unit case mix.
