Abstract

Titanium (Ti) and titanium alloys are among the most-commonly used metallic materials for implantation in the human body for the purpose of replacing hard tissue. Although Ti and its alloys are widely used for such an aim, in implants of a long duration they exhibit some shortcomings due to the loosening of the very implant. This phenomenon is highly dependent on the interaction between the organic tissues and the surface of the implant…..

Resumen

El titanio (Ti) y las aleaciones de titanio están entre los materiales metálicos más comúnmente utilizados para la implantación en el cuerpo humano con el propósito de reemplazar el tejido duro. Aunque Ti y sus aleaciones son ampliamente utilizados para tal fin, en implantes de larga duración presentan algunas deficiencias debidas al aflojamiento del mismo implante. Este fenómeno depende en gran medida de la interacción entre los tejidos orgánicos y la superficie del implante…..

Ketamina / Ketamine

Ketamina. 50 años modulando la mente Ketamine: 50 Years of Modulating the Mind. Li L1, Vlisides PE2. Front Hum Neurosci. 2016 Nov 29;10:612. eCollection 2016. Author information Abstract Ketamine was introduced into clinical practice in the 1960s and continues to be both clinically useful and scientifically fascinating. With considerably diverse molecular targets and neurophysiological properties, ketamine's effects on the central nervous system remain incompletely understood. Investigators have leveraged the unique characteristics of ketamine to explore the invariant, fundamental mechanisms of anesthetic action. Emerging evidence indicates that ketamine-mediated anesthesia may occur via disruption of corticocortical information transfer in a frontal-to-parietal ("top down") distribution. This proposed mechanism of general anesthesia has since been demonstrated with anesthetics in other pharmacological classes as well. Ketamine remains invaluable to the fields of anesthesiology and critical care medicine, in large part due to its ability to maintain cardiorespiratory stability while providing effective sedation and analgesia. Furthermore, there may be an emerging role for ketamine in treatment of refractory depression and Post-Traumatic Stress Disorder. In this article, we review the history of ketamine, its pharmacology, putative mechanisms of action and current clinical applications.

Manejo prehospitalario de la vía aérea / Prehospital airway management

Avances en el manejo prehospitalario de la vía aérea Advances in prehospital airway management. Jacobs P1, Grabinsky A1. Int J Crit Illn Inj Sci. 2014 Jan;4(1):57-64. doi: 10.4103/2229-5151.128014. Abstract Prehospital airway management is a key component of emergency responders and remains an important task of Emergency Medical Service (EMS) systems worldwide. The most advanced airway management techniques involving placement of oropharyngeal airways such as the Laryngeal Mask Airway or endotracheal tube. Endotracheal tube placement success is a common measure of out-of-hospital airway management quality. Regional variation in regard to training, education, and procedural exposure may be the major contributor to the findings in success and patient outcome. In studies demonstrating poor outcomes related to prehospital-attempted endotracheal intubation (ETI), both training and skill level of the provider are usually often low. Research supports a relationship between the number of intubation experiences and ETI success. National standards for certification of emergency medicine provider are in general too low to guarantee good success rate in emergency airway management by paramedics and physicians. Some paramedic training programs require more intense airway training above the national standard and some EMS systems in Europe staff their system with anesthesia providers instead. ETI remains the cornerstone of definitive prehospital airway management, However, ETI is not without risk and outcomes data remains controversial. Many systems may benefit from more input and guidance by the anesthesia department, which have higher volumes of airway management procedures and extensive training and experience not just with training of airway management but also with different airway management techniques and adjuncts.

Christ M1, von Auenmueller KI1, Amirie S1, Sasko BM1, Brand M1, Trappe HJ1. Med Sci Monit. 2016 Jun 13;22:2013-20. Abstract BACKGROUND More than half of all non-traumatic out-of-hospital cardiac arrest (OHCA) patients die in the hospital. Early-onset pneumonia (EOP) has been described as one of the most common complications after successful cardiopulmonary resuscitation. However, the expanded use of alternative airway devices (AAD) might influence the incidence of EOP following OHCA. MATERIAL AND METHODS We analyzed data from all OHCA patients admitted to our hospital between 1 January 2008 and 31 December 2014. EOP was defined as proof of the presence of a pathogenic microorganism in samples of respiratory secretions within the first 5 days after hospital admission. RESULTS There were 252 patients admitted: 155 men (61.5%) and 97 women (38.5%), with a mean age of 69.1±13.8 years. Of these, 164 patients (77.6%) were admitted with an endotracheal tube (ET) and 62 (27.4%) with an AAD. We found that 36 out of a total of 80 respiratory secretion samples (45.0%) contained pathogenic microorganisms, with Staphylococcus aureus as the most common bacteria. Neither bacterial detection (p=0.765) nor survival rates (p=0.538) differed between patients admitted with ET and those with AAD. CONCLUSIONS Irrespective of increasing use of AAD, the incidence of EOP remains high.
