Article Synopsis
- Additive manufacturing of porous materials, particularly through selective laser melting (SLM), is revolutionizing the production of customized medical implants like stents, offering benefits such as greater design freedom and reproducibility.
- The paper discusses the SLM fabrication process for CoCr stents, detailing the initial analysis of CoCr powder and a two-stage method to ensure both quality and accuracy in manufacturing.
- Overall, the development includes simulating a single-track fusion process and analyzing various manufacturing conditions, leading to insights on optimizing laser parameters and refining surface quality of stents.
We compared two de-escalation strategies guided by either extravascular lung water or global end-diastolic volume-oriented algorithms in patients with sepsis and ARDS. Sixty patients with sepsis and ARDS were randomized to receive de-escalation fluid therapy, guided either by the extravascular lung water index (EVLWI, = 30) or the global end-diastolic volume index (GEDVI, = 30). In cases of GEDVI > 650 mL/m or EVLWI > 10 mL/kg, diuretics and/or controlled ultrafiltration were administered to achieve the cumulative 48-h fluid balance in the range of 0 to -3000 mL.

Design: A single-center, prospective, observational study.
Setting: At a 1,000-bed university hospital.
Objective: This study aimed to assess the predictive value of invasive and non-invasive dynamic parameters for evaluation of fluid responsiveness after off-pump coronary artery bypass grafting.
Methods: Thirty-two adult patients after off-pump coronary surgery were enrolled into a single-center pilot prospective observational study. After arrival to the intensive care unit, all patients received standard fluid challenge test to assess fluid responsiveness.
The Relevance Of The Study: Is dictated by the insufficient strength of the bases of removable plate prostheses made of acrylic plastic masses. The literature data confirm the high prevalence of strips of removable plate prostheses made of acrylic plastics, regardless of the complexity of the clinical situation, but in great dependence on the time of use of prostheses. The search for new approaches to reduce the risks of structural failures, regardless of the operating time, led to the emergence of a metal mesh and a composite frame.
