OBJECTIVE Sternum infection remains one of the primary causes of postoperative morbidity and mortality after median sternotomy. We report the clinical efficacy for primary reinforcement of the sternum with a new design of thorax support vest. METHODS A prospective randomized study including 455 patients was started in September 2007 to evaluate the effectiveness of the Posthorax sternum vest ...

We present a new package, VEST (Vector Einstein Summation Tools), that performs abstract vector calculus computations in Mathematica. Through the use of index notation, VEST is able to reduce three-dimensional scalar and vector expressions of a very general type to a well defined standard form. In addition, utilizing properties of the Levi-Civita symbol, the program can derive types of multi-te...

Aortic flow and pressure relations and aortic diameter were examined during sinus rhythm, internal cardiac massage, vest cardiopulmonary resuscitation, conventional manual cardiopulmonary resuscitation and high impulse manual cardiopulmonary resuscitation in 14 anesthetized large dogs. During sinus rhythm and during internal cardiac massage, ascending aortic flow and pressure increased simultan...

Wearing a liquid cooling garment (LCG) that offers near-zone improves the thermal comfort of pilots working in hot environments. Four LCG samples with different arrangements tubes for distributing were developed. Based on analysis overall and local efficiency four using manikin tests, another novel horizontal-vertical combined tube was proposed to achieve optimal performance. Human trials condu...

Background: Personal protective equipment (PPE) is an essential component of safely treating suspected or confirmed SARS-CoV-2 patients. PPE acts as a barrier to heat loss, therefore increasing the risk thermal strain which may impact on cognitive function. Healthcare workers (HCWs) need be able prioritize and execute complex tasks effectively ensure patient safety. This study evaluated pre-coo...

Nowadays, despite the evolution of personal protective equipment (PPE), number firefighters injured and burned during fire extinguishing operations is still very high, leading in some cases to loss life. Therefore, research development new solutions minimize firefighters’ heat load skin burns, with consecutive improvements commercial suits, extreme importance. The integration phase change mater...
