Providing bone turnover marker results is not an effective way to enhance early compliance and persistence with drug therapy. While the women in our study felt that bone marker results and educational information were helpful to them, there was no difference in persistence between those who received either bone marker information and/or educational information and those who did not. Because of the unexpected rate of primary nonadherence, this study may be underpowered.
Background and Objectives Remdesivir is an antiviral drug used to treat coronavirus disease 2019 (COVID-19) with a relatively obscure cardiac effect profile. Previous studies have reported bradycardia associated with remdesivir, but few have examined its clinical characteristics. The objective of this study was to investigate remdesivir associated bradycardia and its associated clinical characteristics and outcomes. Methods This is a single-institution retrospective study that investigated bradycardia in 600 patients who received remdesivir for treatment of COVID-19. A total of 375 patients were included in the study after screening for other known causes of bradycardia (atrioventricular [AV] nodal blockers). All patients were analyzed for episodes of bradycardia from when remdesivir was initiated up to 5 days after completion, a time frame based on the drug’s putative elimination half-life. Univariate and multivariate statistical tests were conducted to analyze the data. Results The mean age of the sample was 56.63 ± 13.23 years. Of patients who met inclusion criteria, 49% were found to have bradycardia within 5 days of remdesivir administration. Compared to the cohort without a documented bradycardic episode, patients with bradycardia were significantly more likely to experience inpatient mortality (22% vs 12%, p = 0.01). The patients with bradycardia were found to have marginally higher serum D-dimer levels (5.2 vs 3.4 µg/mL, p = 0.05) and were more likely to undergo endotracheal intubation (28% vs 14%, p = 0.008). Male sex, hyperlipidemia, and bradycardia within 5 days of completing remdesivir were significant predictors of inpatient mortality. No significant differences in length of stay were found. Conclusions Bradycardia that occurs during or shortly after remdesivir treatment in COVID-19 patients may be associated with an increased rate of in-hospital mortality. However, COVID-19 and its cardiac complications cannot be excluded as potential contributors of bradycardia in the present study. Future studies are needed to further delineate the cardiac characteristics of COVID-19 and remdesivir.

Objective. To compare the efficacy, discontinuation rates, and safety of once nightly versus twice daily dosing of pregabalin in a community-based trial. Methods. This multicenter, double-blind, 8-week randomized clinical trial compared the effects of 300-mg daily doses of pregabalin given either twice daily or once nightly for the treatment of fibromyalgia in 177 patients. The primary outcome was the comparison of end point mean pain scores derived from a daily diary. Results. Both twice daily (88 patients randomized) and once nightly (89 patients) pregabalin significantly reduced the average severity of pain experienced by patients (P < 0.001 for both). Treatment-emergent adverse events were reported by significantly more patients in the twice daily group than those in the once nightly group (P ؍ 0.023). There were no significant differences between the groups for the frequencies of individual adverse events (P > 0.05 for all). There was no significant difference in adverse events or efficacy in patients taking both pregabalin and a selective serotonin and norepinephrine reuptake inhibitor or selective serotonin uptake inhibitor. Conclusion. While a nightly dosing schedule of pregabalin has been used by clinicians hoping to improve treatment, this study showed no significant difference (either beneficial or detrimental) between either treatment option. While there was a decrease in total patient-reported adverse events in the once nightly arm, the lack of specificity in relation to a particular adverse event suggested no real difference in adverse events.
Teriparitide (TPD) is a novel anabolic agent that stimulates bone formation. TPD reduces risk of vertebral and nonvertebral fracture. Due to its positive effects on bone formation, many new uses of TPD are being explored. It has been studied and approved for glucocorticoid-induced osteoporosis. Many questions about the use of TPD remain including use of follow-up therapy, combination therapy, sequential therapy, and its potential role in fracture healing and treatment of back pain related to osteoporosis.
IntroductionThe FRAX calculator combines a set of clinical risk factors with country-specific incidence rates to determine the ten-year absolute risk of major osteoporotic fracture. However, regional or country-specific databases from Central American countries are not available. We compared the use of various FRAX databases and the Pluijm algorithm in determining risk of fracture.MethodsWe collected clinical risk factor data needed for the FRAX calculator and Pluijm algorithm of Hispanic women in Guatemala and calculated the FRAX absolute risk measures of major osteoporotic fracture and hip fracture. Subjects were postmenopausal women greater than age 40 with no history of using medication that affect bone. A random sample of 204 women in 34 different regions women in Guatemala City was visited in their homes to complete the surveys. The Pluijm risk score and FRAX risk score using the US Hispanic, Spain, and Mexican databases were calculated.ResultsWe used the US NOF guidelines for treatment which suggest a treatment threshold for patients with a 10-year hip fracture probability ≥3% or a 10-year major osteoporotic fracture risk ≥20%. The number of patients meeting the suggested threshold limits for treatment using the Spain and Mexico calculators were identical. There was 100% conformity in threshold limits for both hip and major osteoporotic fracture risk. The mean conformity for any fracture risk between US Hispanic and the other two databases was 97.5%. Conformity was 99.0% based on major osteoporotic fracture and 97.5% based on risk of hip fracture. The Pluijm evaluation shows conformity of 87.2% and 83.3%, respectively, when compared to the US Hispanic and Spain/Mexico FRAX thresholds for risk of fracture.DiscussionAlthough the different FRAX databases provide variations in the absolute risk of fracture, the overall conformity to treatment thresholds amongst the US Hispanic, Spain, and Mexico databases show the database used would have little effect as to the decision to treat. The Pluijm tool conforms to the FRAX thresholds and can be used as well. It does not matter which country-specific calculator or assessment tool is used, as there are a similar number of patients that would meet the intervention threshold.
