Topical tranexamic acid in hip fractures: a randomized, placebo-controlled double-blinded study.

BACKGROUND: Tranexamic acid (TXA) has been shown to reduce perioperative blood loss in elective orthopedic surgery. The safety of intravenous TXA in nonelective hip fracture surgery is uncertain. The purpose of this study was to evaluate the efficacy and safety of topical TXA in hip fracture surgery. METHODS: Adult patients presenting to a community hospital with a hip fracture requiring surgery were randomly assigned to receive topical TXA or placebo. Hemoglobin and troponin I levels were measured preoperatively and on postoperative days 1, 2 and 3. All postoperative blood transfusions were recorded. Complications, including acute coronary syndrome (ACS), venous thromboembolism (VTE), cerebrovascular accidents (CVA), surgical site infections (SSI) and 90-day mortality, were recorded. RESULTS: Data were analyzed for 65 patients (31 in the TXA group, 34 in the control group). Hemogloblin level was significantly higher on postoperative days 1 and 2 in the TXA group than in the control group. The difference in hemoglobin level between the groups was not statistically significant by postoperative day 3. Significantly fewer units of packed red blood cells were transfused in the TXA group (2 units v. 8 units); however, 2 of the units in the control group were given intraoperatively, and when these were excluded the difference was not significant. The incidence of ACS, CVA, VTE, SSI, transfusion and all-cause mortality at 90 days did not differ significantly between the groups. CONCLUSION: Topical TXA reduces early postoperative blood loss after hip fracture surgery without increased patient risk. TRIAL REGISTRATION: Clinicaltrials.gov, no. NCT02993341.

Surgical peripheral nerve decompression for the treatment of painful diabetic neuropathy of the foot - A level 1 pragmatic randomized controlled trial.

AIMS: To assess the efficacy of surgical decompression of lower extremity nerves for the treatment of painful diabetic peripheral sensorimotor polyneuropathy (DPN). METHODS: People with painful diabetic neuropathy were randomized single-blind to a lower extremity decompression surgery (n = 12) or observation (n = 10) for 1 year. RESULTS: Pain was the primary outcome assessed with 2 measures. The McGill pain visual analogue scores over time changed within the groups (p for time < 0.0001), and changed differently over time within the groups (p for group × time = 0.0138). The NeuroQoL pain sensitivity analysis significantly changed from baseline to 12 months comparing intervention to control (p = 0.0079), and the joint effect of group and time on pain scores was statistically significant (p for group × time = 0.0009). At the study end-point of 12 months, intervention group participants had over 3 times the odds of rating their pain as "better" compared to "unchanged" or "worse" in the control group (p = 0.0177). CONCLUSIONS: Surgical decompression of lower limb nerves was an effective treatment for decreasing pain in patients with DPN and superimposed nerve compressions.

Community based intervention to optimize osteoporosis management: randomized controlled trial.

BACKGROUND: Osteoporosis-related fractures are a significant public health concern. Interventions that increase detection and treatment of osteoporosis are underutilized. This pragmatic randomised study was done to evaluate the impact of a multifaceted community-based care program aimed at optimizing evidence-based management in patients at risk for osteoporosis and fractures. METHODS: This was a 12-month randomized trial performed in Ontario, Canada. Eligible patients were community-dwelling, aged ≥55 years, and identified to be at risk for osteoporosis-related fractures. Two hundred and one patients were allocated to the intervention group or to usual care. Components of the intervention were directed towards primary care physicians and patients and included facilitated bone mineral density testing, patient education and patient-specific recommendations for osteoporosis treatment. The primary outcome was the implementation of appropriate osteoporosis management. RESULTS: 101 patients were allocated to intervention and 100 to control. Mean age of participants was 71.9 ± 7.2 years and 94% were women. Pharmacological treatment (alendronate, risedronate, or raloxifene) for osteoporosis was increased by 29% compared to usual care (56% [29/52] vs. 27% [16/60]; relative risk [RR] 2.09, 95% confidence interval [CI] 1.29 to 3.40). More individuals in the intervention group were taking calcium (54% [54/101] vs. 20% [20/100]; RR 2.67, 95% CI 1.74 to 4.12) and vitamin D (33% [33/101] vs. 20% [20/100]; RR 1.63, 95% CI 1.01 to 2.65). CONCLUSIONS: A multi-faceted community-based intervention improved management of osteoporosis in high risk patients compared with usual care. TRIAL REGISTRATION: This trial has been registered with clinicaltrials.gov (ID: NCT00465387).
