At 5 years, these outcomes are not significantly different between comparing groups. The complication and reoperation rate of two groups are similar both at 2 and at 5 years. In conclusion,
TDR does not show significant superiority for the treatment of lumbar DDD compared with fusion. The benefits of motion preservation and the long-term complications are still unable to be concluded. More high-quality RCTs with long-term follow-up are needed.”
“Objective: Evaluate the surgical results of axis screw instrumentation. Methods: Retrospective evaluation of the clinical and radiological data of patients submitted to axis fixation using screws. Results: Seventeen patients were surgically treated. The mean age was 41.8 years (range: GM6001 clinical trial 12-73). Spinal cord trauma was the most common cause of instability (8 patients – 47%). Bilateral axis fixation was performed in all cases, except one, with laminar screw (total of 33 axis screws). Seven patients (41.1%) underwent bilateral pars screws; laminar screws were used in six cases and pedicular screws were used in two. In two cases, we performed a hybrid construction (laminar + pars and pedicle
+ pars). There was no neurological worsening or death, nor complications directly related to use axis screws. Conclusion: Axis instrumentation was effective and safe, regardless of the technique used for stabilization. Based on our learnt experience, we proposed an algorithm to choose the best technique for axis screw fixation.”
“Background: Gender-specific differences in cardiovascular MLN4924 cost risk are well known, and current evidence Crenigacestat in vivo supports an existing
role of endothelium in these differences. The purpose of this study was to assess non invasively coronary endothelial function in male and female young volunteers by myocardial blood flow (MBF) measurement using coronary sinus (CS) flow quantification by velocity encoded cine cardiovascular magnetic resonance (CMR) at rest and during cold pressor test (CPT).
Methods: Twenty-four healthy volunteers (12 men, 12 women) underwent CMR in a 3 Tesla MR imager. Coronary sinus flow was measured at rest and during CPT using non breath-hold velocity encoded phase contrast cine-CMR. Myocardial function and morphology were acquired using a cine steady-state free precession sequence.
Results: At baseline, mean MBF was 0.63 +/- 0.23 mL.g(-1).min(-1) in men and 0.79 +/- 0.21 mL.g(-1).min(-1) in women. During CPT, the rate pressure product in men significantly increased by 49 +/- 36% (p < 0.0001) and in women by 52 +/- 22% (p < 0.0001). MBF increased significantly in both men and women by 0.22 +/- 0.19 mL.g(-1).min(-1) (p = 0.0022) and by 0.73 +/- 0.43 mL.g(-1).min(-1) (p = 0.0001), respectively. The increase in MBF was significantly higher in women than in men (p = 0.0012).
