ReviewUnderstanding the complexity of cardiogenic shock management: the added value of advanced computational modeling.
The purpose of this review is to explain the value of computational physiological modeling for in-depth understanding of the complex derangements of cardiopulmonary pathophysiology during cardiogenic shock, particularly when treated with temporary mechanical circulatory support (tMCS) devices. ⋯ The use of computational physiological models is increasingly appreciated for educational purposes as they help to understand the complexity of cardiogenic shock, especially when sophisticated management of tMCS is involved in addition to multimodal critical care support. Practical implementation of computational models as clinical decision support tools at the bedside is at the horizon but awaits rigorous clinical validation.

ReviewBeyond one-size-fits-all in cardiogenic shock: impella, extracorporeal membrane oxygenation or tailored use of mechanical circulatory support?
This article offers an overview of recent randomized controlled trials (RCTs) testing the efficacy of veno-arterial extracorporeal membrane oxygenation (VA ECMO) and microaxial flow pump (mAFP) in treating cardiogenic shock, including findings from the DanGer shock trial. It summarizes the clinical implications and limitations of these studies and key decision-making considerations for cardiogenic shock device use. ⋯ Recent trials offer insights into mechanical circulatory support in cardiogenic shock, but their real-world applicability is limited. Despite potential benefits, the use of VA ECMO and mAFP is associated with significant complication rates, emphasizing the need for personalized use.

The use of noninvasive techniques [noninvasive ventilation (NIV) or high flow nasal cannula (HFNC) oxygen therapy] to support oxygenation and/or ventilation in patients with respiratory failure has become widespread, even more so since the coronavirus disease 2019 pandemic. The use of these modalities may impair the patient's ability to eat. "To breath or to eat" may become a dilemma. In this review, we identify the patients at risk of malnutrition that require medical nutritional therapy and understand the mechanisms of function of the devices to better give adapted nutritional indications for noninvasive ventilation or high flow nasal cannula. ⋯ The patient requiring noninvasive ventilation presents one of the most challenging nutritional challenges. The main steps to improve nutrition administration are to assess nutritional status, evaluate the presence of dysphagia, choose the most adequate tool of respiratory support, and adapt nutritional therapy (oral, enteral, or parenteral) accordingly.

ReviewProtected cardiac surgery: strategic mechanical circulatory support to improve postcardiotomy mortality.
To examine the evolving landscape of cardiac surgery, focusing on the increasing complexity of patients and the role of mechanical circulatory support (MCS) in managing perioperative low cardiac output syndrome (P-LCOS). ⋯ This paper explores the shifting demographics and complexities in cardiac surgery patients. It emphasizes the importance of proactive, multidisciplinary approaches to identify high-risk patients and implement early MCS to prevent P-LCOS and improve outcomes. The concept of protected cardiac surgery, involving planned MCS use and shared decision-making, is highlighted. The paper also discusses MCS strategies tailored to specific cardiac procedures and the ethical considerations surrounding MCS implementation.
