Concept: Safe


This paper presents an innovative access control system, based on human detection and path analysis, to reduce false automatic door system actions while increasing the added values for security applications. The proposed system can first identify a person from the scene, and track his trajectory to predict his intention for accessing the entrance, and finally activate the door accordingly. The experimental results show that the proposed system has the advantages of high precision, safety, reliability, and can be responsive to demands, while preserving the benefits of being low cost and high added value.

Over 50,000 homicides and suicides occur each year. An estimated half of all U.S. households are believed to have a firearm present, making them one of the most ubiquitous consumer products. Our goal was to determine if the manner of storage of a firearm in a home could potentially make a difference in the outcomes of intentional and unintentional injuries involving a firearm; specifically addressing the use of gun safes and devices that block/disable firearm function (trigger locks, cable locks, etc.).

Ultrasound-guided PCNL in Galdakao-modified supine Valdivia (GMSV) position has taken into consideration during the last decade; however, guidewire slippage during tract dilatation is still a big concern in this approach. Here we presented our results of combination of this modification with ureteroscopic guidewire retrieval to ensure a safe and confident renal access.

Some studies have suggested that radial access (RA) for percutaneous coronary intervention (PCI) reduces vascular complications and bleeding compared to femoral access (FA). The purpose of this study was to investigate the routine use of hemostatic devices and bleeding complications among RA, brachial access (BA), and FA. Between January 2015 and December 2015, 298 patients treated for PCI with RA were compared with 158 patients using BA and 206 patients using FA. The radial sheath was routinely removed with ADAPTY, the brachial sheath with BLEED SAFE, and the femoral sheath with Perclose ProGlide. In-hospital bleeding complications were investigated. Cardiogenic shock was most frequent in patients in the femoral group (RA 1.3%, BA 2.5%, FA 9.2%, p < 0.0001). The rate of major bleeding was highest in the femoral group (RA 1.0%, BA 2.5%, FA 5.3%, p = 0.01). Blood transfusion rates were highest in the femoral group (RA 0.7%, BA 1.3%, FA 4.4%, p = 0.01). Retroperitoneal bleeding was observed in 1.9% of patients in the femoral group. Patients in the brachial group had large hematomas (RA 0.7%, BA 4.4%, FA 1.5%, p = 0.01). Pseudoaneurysm formation needing intervention occurred most frequently in the brachial group (RA 0%, BA 1.3%, FA 0%, p = 0.04). In conclusion, compared to the brachial and femoral approaches, the radial approach appears to be the safest technique to avoid local vascular bleeding complications. The brachial approach has the highest risk of large hematoma and pseudoaneurysm formation among the three groups.

The importance of mechanical thrombectomy in acute stroke treatment has grown over recent years. Mechanical thrombectomy comprises many different techniques. Technical improvements in the catheter material have led to the development of large-bore distal access catheters which can enter tortuous intracranial vessels. This has promising applications for endovascular stroke treatment. This study evaluated the safety and success rate of ultra-distal access of the middle cerebral artery (MCA) M1 segment with the 5 Fr Navien 58 distal access catheter in the treatment of acute stroke in combination with stent retrievers.

Several surgical approaches to the posterior malleolus have been described. However, these approaches may make it difficult for fixation of associated lateral malleolar and anterior syndesmotic fractures. A single incision approach is described that allows safe access to the posterior malleolus while also facilitating access to the lateral malleolus and anterior syndesmosis.
