Cardiovascular disease is the leading cause of morbidity and mortality among patients with diabetes mellitus, as well as the leading diabetes-associated health care cost. The prevalence and associated impact of cardiovascular disease among those with diabetes engenders the need to identify cardiovascular effects of antihyperglycemic agents. This review seeks to evaluate the impact of canagliflozin, a SGLT2 inhibitor, on cardiovascular risk factors and outcomes. The 14 published trials to-date exploring various cardiovascular risk factors and outcomes among patients receiving canagliflozin were identified and included within the review. Overall these studies demonstrate that among patients with type 2 diabetes mellitus, canagliflozin results in decreased systolic and diastolic blood pressure, lower body weight, and also exhibits reno-protective effects. These findings were similar when canagliflozin was compared to placebo or other antihyperglycemic agents and explored among subsets such as those with chronic kidney disease. In addition, findings from the three trials exploring cardiovascular outcomes of canagliflozin included reduction in cardiovascular mortality and lower incidence of heart failure-associated hospitalizations. Results from studies including other SGLT2 inhibitors suggest that cardiovascular benefits are likely a class-effect found among current SGLT2 inhibitors. Continued research specific to canagliflozin is needed to clarify risks of adverse effects and determine optimal dosing requirements for canagliflozin in regard to cardiovascular risk reduction.

Purpose: Rifampin is commonly used to treat device-related infections (DRIs) due to its activity against biofilms, despite a history of limited clinical evidence to support its use. Evidence published since 2011 regarding rifampin use for DRIs is reviewed to describe the contemporary findings and ongoing considerations for rifampin use in these infections. Summary: A literature review was performed by searching PubMed and Google Scholar to identify relevant studies evaluating systemic rifampin use for the treatment of DRIs published from 2011 to 2023. References of identified studies were also screened for additional pertinent studies. Sixty-eight studies were identified, and 48 met the inclusion criteria. Rifampin efficacy was evaluated as both a primary outcome for cardiac device infections (n = 3) and prosthetic joint infections (n = 21) and as a nonprimary outcome (n = 24). Overall, the studies were primarily retrospective (n = 36) and small, with sample sizes ranging from 14 to 842 patients, and varied greatly with respect to prosthesis site, surgical intervention, pathogen, infection time frame, and antibiotic combination and duration. Efficacy outcome results varied greatly, with statistically significant evidence for the efficacy of rifampin combination in DRIs limited to a single study of prosthetic vascular graft infections and 13 studies of prosthetic joint infections. Conclusion: The modern literature provides conflicting results regarding the benefit and lack of benefit with rifampin combination therapy in DRIs. Additional, robust research is imperative to solidify the ongoing role of rifampin in DRIs.

IntroductionDuring menopause, the majority of women experience vasomotor symptoms which may lead to several untoward effects and negatively impact quality of life. Fezolinetant, a novel agent directly targeting the underlying pathophysiology of menopause-associated vasomotor symptoms, offers an alternative to hormonal therapies for which many patients have a contraindication or unwillingness to take due to safety concerns.Areas coveredThis review summarizes key pharmacologic, pharmacokinetic, and pharmacodynamic parameters of fezolinetant along with efficacy and safety data derived from clinical trials. A literature search of peer-reviewed publications evaluating the efficacy and safety of fezolinetant was conducted using PubMed and EMBASE databases. A review of registered trials in clinicaltrials.gov was evaluated to identify ongoing studies.Expert opinionPlacebo-controlled studies demonstrated that fezolinetant led to a statistically significant reduction in vasomotor symptom frequency and severity among patients with moderate-to-severe vasomotor symptoms. The most common adverse event is headache (5-10%) and no serious safety signals have been noted. Direct head-to-head comparison with hormonal therapies and nonhormonal therapies for vasomotor symptoms, assessment of sleep outcomes, and evaluation of efficacy and safety beyond 1 year are key areas where additional data are still needed.
