ReviewEvolving Role of Local Anesthetics in Managing Postsurgical Analgesia.
Opioid analgesics, the cornerstone of effective postsurgical pain management, may be associated with risk of opioid-related adverse drug events (ADEs) that may complicate the postsurgical experience. Perioperative multimodal analgesic regimens have the potential to improve postsurgical pain control and may permit use of lower analgesic doses and reduce the incidence of opioid-related ADEs. Utility of traditional local anesthetic formulations to provide analgesia over the entire postsurgical period is limited by their short duration of action. Liposome bupivacaine, a liposomal formulation of bupivacaine indicated for single-dose administration into the surgical site to produce postsurgical analgesia, was evaluated in multiple surgical models as part of multimodal analgesic regimens and was found in clinical trials to provide postsurgical analgesia for up to 72 hours. Here, we provide an overview of the available multimodal analgesic options and recent recommendations for optimal postsurgical pain management. ⋯ Use of multimodal analgesic regimens is a practical way to achieve good postsurgical analgesia while minimizing reliance on opioids and associated adverse events. Taken as a whole, evidence from the clinical studies of liposome bupivacaine suggests this local anesthetic formulation may be a useful component of multimodal analgesic regimens for managing postsurgical pain in select patients, with the potential to reduce opioid use and opioid-related ADEs in the postsurgical setting. As with bupivacaine, appropriate use of liposome bupivacaine to optimize clinical effects, economic implications, and patient tolerability will depend on appropriate patient selection, practitioner training, and institutional protocols. As a component of a multimodal analgesic regimen, liposome bupivacaine represents a new approach to extending the duration of postsurgical analgesia. Further studies across a range of surgical settings should help clarify the most appropriate roles for this prolonged-release formulation of bupivacaine.

ReviewThe Role of Sodium-Glucose Co-Transporter 2 Inhibitors in the Treatment of Type 2 Diabetes.
Diabetes is a chronic metabolic disorder characterized by hyperglycemia that results from insulin resistance, diminished or absent insulin secretion, or both. Approximately one-half of patients with diabetes fail to achieve acceptable glycemic control. Consequently, morbidity and mortality associated with diabetes is high, resulting from complications such as cardiovascular disease and nephropathy. The sodium-glucose co-transporter 2 (SGLT2) inhibitors are a new class of medications for the treatment of type 2 diabetes. This article provides an overview of efficacy and safety data for the SGLT2 inhibitors and outlines their role in the management of diabetes. ⋯ With their unique mechanism of action and good safety and tolerability profiles, the SGLT2 inhibitors are an important addition to existing treatments for type 2 diabetes. Because of the lack of data with this class of drugs when current treatment guidelines for diabetes were published, the SGLT2 inhibitors are recommended as second- or third-line therapies for diabetes. Forthcoming data on the long-term efficacy and safety profile of these agents should help to solidify the role of SGLT2 inhibitors in the management of diabetes.

Meta AnalysisExamining the Time to Therapeutic Effect of Pregabalin in Spinal Cord Injury Patients With Neuropathic Pain.
In 2 large-scale, placebo-controlled trials, pregabalin improved both pain and pain-related sleep interference in patients with neuropathic pain due to spinal cord injury (SCI). In both trials, pregabalin found statistically significant improvement compared with placebo after 1 week of treatment. However, the effects of pregabalin in the days immediately after initiation of treatment are unknown. The purpose of the present analysis was to determine timing of pregabalin's therapeutic effect in the days after initiation of treatment. ⋯ Treatment with pregabalin results in rapid time to significant improvement in both pain and pain-related sleep interference in patients with neuropathic pain due to SCI. These findings should only be used as a guide to physicians and patients as to when clinical response to pregabalin may be expected.

Meta AnalysisPerioperative Pregabalin for Acute Pain After Gynecological Surgery: A Meta-analysis.
Pregabalin has been used as an adjuvant in some trials to control postoperative pain after gynecologic surgery. However, the potential clinical advantage remains debatable. ⋯ Pregabalin has an analgesic and opioid-sparing effect and does not increase the frequency of adverse effects in acute postoperative pain management after gynecologic surgery.

ReviewGut-Microbiota-Brain Axis and Its Effect on Neuropsychiatric Disorders With Suspected Immune Dysregulation.
Gut microbiota regulate intestinal function and health. However, mounting evidence indicates that they can also influence the immune and nervous systems and vice versa. This article reviews the bidirectional relationship between the gut microbiota and the brain, termed the microbiota-gut-brain (MGB) axis, and discusses how it contributes to the pathogenesis of certain disorders that may involve brain inflammation. ⋯ Recognition of the relationship between the MGB axis and the neuroimmune systems provides a novel approach for better understanding and management of these disorders. Appropriate preventive measures early in life or corrective measures such as use of psychobiotics, fecal microbiota transplantation, and flavonoids are discussed.
