Advances in virtual surgical planning and three-dimensionally-printed guides have enabled increased precision in vascularized free fibula flap reconstruction of the mandible and valuable preoperative planning. However, virtual surgical planning currently requires high-resolution computed tomographic scans, exposing patients to ionizing radiation. The aim of this study was to determine whether black bone magnetic resonance imaging can be used for accurate surgical planning and three-dimensionally-printed guide creation, thus reducing patient radiation exposure. This study included 10 cadaver heads and 10 cadaver lower extremities. A mock fibula free flap for mandible reconstruction was performed. Five operations were planned with guides created using black bone magnetic resonance imaging, whereas the other five were planned and performed using guides created with computed tomographic scan data. All specimens underwent a postoperative computed tomographic scan, and three-dimensional reconstruction of scans waic resonance imaging demonstrated high accuracy to the surgical plan. There was no statistically significant difference in postoperative deviation from the plan when black bone magnetic resonance imaging versus computed tomographic scanning was used for virtual surgical planning and guide creation. Both modalities led to a postoperative positive or negative deviation from the virtual plan within 0.8 mm. This study demonstrates that virtual surgical planning and three-dimensionally-printed guide creation for free fibula flaps for mandible reconstruction can be performed using black bone magnetic resonance imaging with comparable accuracy to computed tomographic scanning. This could reduce radiation exposure for patients and enable a more streamlined imaging process for head and neck cancer patients.
Venous thromboembolism is a common complication after hip fractures. However, there are no reliable laboratory assays to identify patients at risk for venous thromboembolic (VTE) events after major orthopaedic surgery.

(1) Are rotational thromboelastometry (ROTEM) findings associated with the presence or development of symptomatic VTE after hip fracture surgery? (2) Were any other patient factors associated with the presence or development of symptomatic VTE after hip fracture surgery? (3) Which ROTEM parameters were the most accurate in terms of detecting the association of hypercoagulability with symptomatic VTE?

This retrospective study was conducted over a 13-month period. In all, 354 patients with femoral neck and peritrochanteric fractures who underwent hip hemiarthoplasty or cephallomedullary nailing were assessed for eligibility. Of those, 99% (349 of 354) were considered eligible for the study, 1% (3 of 354) of patients were excluded due to coagulation disorders, and another 1% (2 of 354) were work by demonstrating that ROTEM has a high accuracy in detecting the level of hypercoagulability that is associated with symptomatic VTE. However, until its performance is validated in a study that applies a diagnostic gold standard (such as venography, duplex/Doppler, or chest CT) in all patients having ROTEM to confirm its performance, ROTEM should not be used as a regular part of clinical practice.

We sought to determine the racial and ethnical disparities in the delivery of TAVR and to evaluate the in-hospital outcomes and utilization of TAVR stratified by patient ethnicity.

Using a national inpatient sample database between 2011 and 2015, we identified all adult patients who had TAVR. Races were identified and white race was set as control. Multiple logistic regression analysis was performed for the primary outcome of in-hospital mortality.

Out of 58 174 patients who underwent TAVR, 50 809 (87.3%) were white, 2327 (4.0%) were black, 2311 (4.0%) were Hispanic, 640 (1.1%) Asian, 105 (0.2%) Native American and 1982 (3.4%) of other ethnicities. We found a statistically significant linear uptrend in the utilization of TAVR in patients of all races between the years 2011 and 2015. White, black, Hispanic and Native American patients had a downward linear trend for mortality during the studied years (P ≤ 0.005 for all). Black patients had lower in-hospital mortality [2.8 vs. 3.6%, odds ratio (OR) = 0.62; 95% confidence interval (CI) 0.44, 0.81 P < 0.001] compared with white patients, whereas Hispanic patients and Native Americans had higher in-hospital mortality compared with white patients (4.5% OR 1.26; 95% CI 1.01, 1.56 P = 0.041), (9.5% OR 4.44; 95% CI 2.25, 8.77 P < 0.001), respectively.

Overall, TAVR utilization is associated with lower mortality. There is a rising trend in utilization of TAVR in the black population with a significantly favorable mortality trend compared with the white population.

Acute kidney injury (AKI) may complicate transcatheter aortic valve replacement (TAVR) leading to higher mortality. Cilengitide in vivo The relationship between AKI, obesity, and mortality, however, is controversial. We sought to investigate the impact of body habitus on the prognostic value of AKI in TAVR.

Among the 645 patients who underwent successful TAVR in a single high-volume centre, we retrospectively evaluated the association between AKI-TAVR and 30-day, 6-month, and 1-year mortality, and whether this relationship was affected by BMI. AKI was defined according to the Valve Academic Research Consortium-2 criteria. Patients were categorized into three groups by BMI low-to-normal weight (<25 kg/m2), overweight (25-30 kg/m2), obese (>30.0 kg/m2).

Three-hundred and twenty-four (50.2%) patients were low-to-normal weight, 223 (34.6%) overweight, and 98 (15.2%) obese. AKI occurred in 141 (21.9%), similarly across BMI groups. Thirty-day, 6-month, and 1-year mortality rates were 2.2, 3.7, and 7.9%, without differences across BMI groups. Among patients who developed AKI-TAVR, 30-day (8.7 vs. 2.0 vs. 0.0%), 6-month (13.0 vs. 6.1 vs. 4.3%), and 1-year (20.3 vs. 12.2 vs. 4.3%) mortality showed a decreasing trend across increasing BMI categories (all P < 0.05); the same trend was not observed for patients without AKI-TAVR. In multivariate models, AKI was associated with 30-day [odds ratio (OR) 2.46, 95% confidence interval (CI) 1.70-8.67], 6-month (OR 2.75, 95% CI 1.32-7.59), and 1-year mortality (OR 1.84, 95% CI 1.22-3.71, all P < 0.05). The interaction between AKI and BMI, when added to the models, was consistently significant (all P < 0.05).

Higher BMI is associated with better survival in TAVR patients who develop AKI.
