Randomized Controlled Trial
The effect of a controlled mandible position mouthguard on upper body strength and power in trained rugby athletes - A randomized within subject study.
It is widely accepted that mouthguards are effective for injury protection in sports. However, findings on the effects of mouthguards in strength and power production remains controversial. Therefore, the aim of this study was to determine whether controlled-mandible position mouthguards influence strength and power production in well trained athletes. ⋯ Controlled mouthguards enhance peak force and peak acceleration in the ballistic bench press exercise without negatively affecting any other measure assessed in this study. We speculate that this is possibly due to an increased stability of temporomandibular joint.

Effect of Dexmedetomidine infusion during hip fracture surgery on hemodynamic parameters and blood loss: A triple-blinded Randomized Clinical Trial.
Introduction In this study, we aim to assess the intra-operative effect of dexmedetomidine administration on the hemodynamic parameters and bleeding volume during hip fracture surgery. Patients and methods we designed and implemented a triple-blinded randomized clinical trial to objectively compare the effects of 0.5 µg/kg/h infusion of dexmedetomidine with placebo (equal amount of normal saline) during hip fracture surgery. All included cases were between 30 and 70 years old and underwent surgery for fixation of a proximal femur fracture from September 26, 2020 until February 15, 2021. ⋯ No significant effect on hemodynamic parameters was observed. Conclusion Based on the current study, intravenous infusion of dexmedetomidine during hip fracture surgery under general anesthesia reduced the amount of intraoperative bleeding without causing any significant hemodynamic disturbances. Registration number IRCT20191222045857N1 (Iranian Registry of Clinical Trials).

Is proximal femoral nailing of unstable intertrochanteric fractures in the lateral decubitus position without a traction table as safe and effective as on a traction table?
Using proximal femoral nailing (PFN) in the lateral decubitus (lateral) position may be an option when no traction table is available. We hypothesized that applying PFN would be effective and reliable in the lateral position without a traction table. To test our hypothesis, we compared the two techniques in a prospective, randomized controlled study. ⋯ We concluded that PFN is a safe and effective alternative for the treatment of unstable intertrochanteric femoral fractures when a traction table is not available in the operating room.

Topical administration of tranexamic acid in elderly patients undergoing short femoral nailing for intertrochanteric fracture: A randomised controlled trial.
Topical application of tranexamic acid (TXA) has been proposed as an alternative to intravenous administration to reduce perioperative bleeding in orthopaedic surgery. The purpose of this randomised controlled trial was to evaluate the efficacy and safety of 1 g topically applied TXA in patients undergoing fixation of intertrochanteric hip fractures by short femoral nailing. ⋯ A 1 g dose of topically administered TXA did not produce any difference in blood loss, transfusion requirements, thromboembolic complications, or 90-day mortality. Future trials may consider the effect of larger doses in patients undergoing hip fracture fixation surgery.

Comparison of vacuum sealing drainage and conventional drainage for postoperative drainage in closed calcaneal fracture: A randomized controlled trial.
The objective of this study was to compare the outcomes of vacuum sealing drainage (VSD) and conventional drainage after surgery in the treatment of closed calcaneal fracture. We hypothesize that VSD is superior to conventional drainage in reducing volume of drainage, time of wound drying, time of skin fold, time of wound healing, VAS at day 3 postoperatively, wound complications and increasing wound healing grade. ⋯ Our hypothesis was confirmed that VSD was superior in terms of some aspects than conventional drainage. Therefore, VSD is a safe and effective postoperative wound drainage method in the treatment of closed calcaneal fracture. However, more and higher evidence needs to be carried to demonstrate the results.
