The free radical nitric oxide (NO) is considered one of the most versatile endogenous molecules and is a crucial signalling molecule in numerous biochemistry pathways of the human body. NO is directly related to pathological processes and plays an important role in many different and interrelated physiological processes. In some cases, a depletion of NO or an attenuation of its effector system could exist as in hypertension, angina and impotence; in others, an overproduction of NO may be a major cause of damage, as in circulatory shock, sepsis, neurodegenerative disorders and inflammatory responses...

Venoarterial extracorporeal membrane oxygenation has emerged as a viable treatment for patients in cardiogenic shock with biventricular failure and pulmonary dysfunction. Advances in pump and oxygenator technology, cannulation strategies, patient selection and management, and durable mechanical circulatory support have contributed to expanded utilization of this technology. However, challenges remain that require investigation to improve outcomes.

Obtaining neuroimaging in patients on cardiopulmonary support devices such as extracorporeal membrane oxygenation (ECMO) can be challenging, given the complexities in monitoring, instrumentation, and associated hemodynamic lability. Transcranial Doppler (TCD) is used as an ancillary test for the assessment of cerebral circulatory arrest, but its use in non-pulsatile blood flow in venoarterial (VA) ECMO is not well described. We report the use of TCD in a patient on VA ECMO post-cardiac arrest for evaluation of death by neurological criteria...

INTRODUCTION: Percutaneous mechanical circulatory support systems have increasingly been adopted as a bail out strategy in patients with cardiogenic shock. Since studies showed mostly mixed results, however, the use of support systems remains a case by case decision. CASE: Here, we report on a case of therapy-refractory cardiogenic shock due to acute myocardial infarction treated with percutaneous right and left ventricular assist devices (Impella RP and CP). CONCLUSION: Due to myocardial stunning, even patients with fulminant cardiogenic shock have the potential for full recovery...

PURPOSE OF REVIEW: To review the different methods available for the assessment of cardiac output (CO) and describe their specific indications in intensive care and perioperative medicine. RECENT FINDINGS: In critically ill patients, persistent circulatory shock after initial resuscitation is an indication for the assessment of CO to monitor the response to fluids and vasoactive agents. In patients with circulatory shock associated with right ventricular dysfunction, pulmonary artery hypertension, or acute respiratory distress syndrome, invasive CO monitoring using indicator dilution methods is indicated...

Acute heart failure is associated with high morbidity and mortality. Heart failure is caused by various conditions, including electrolyte imbalances. We report a rare case of hypercalcaemia-induced acute heart failure complicated by cardiogenic shock. Mechanical circulatory support was used successfully in this patient until calcium homeostasis was restored.

Evidence-based review of the existing literature ultimately recommends stocking of methylene blue (MB) as an emergency antidote in the United States. The same is reported around the world in Japan, Greece, Italy and Canada. The observation that MB is always present as the main antidote required in emergency and critical care units calls for a revisit on its effects on the NO/cGMP system to reemphasize its multisystem actions. Therefore, the present review aimed to display the role of MB in emergency units, concerning: 1) Polytrauma and circulatory shock; 2) Neuroprotection, 3) Anaphylaxis and, 4) Overdose and poisoning...

Background: Obesity is associated with increased risk, poor prognosis and outcome of therapy, in various cancers. Obesity-associated factors or adipokines, especially leptin and resistin, are purported to promote growth, survival, proliferation, and invasiveness of cancer cells. However, the mechanistic link between these adipokines and therapeutic response in malignancies is not clearly understood. Methods: ob/ob and db/db mouse models were used in this study to evaluate the role of leptin and resistin towards the outcome of dacarbazine (DTIC) therapy in melanoma...

REVIEW
Emiel Hendrik Post, Jean-Louis Vincent
The importance of personalized blood pressure management is well recognized. Because renal pressure-flow relationships may vary among patients, understanding how renal autoregulation may influence blood pressure control is essential. However, much remains uncertain regarding the determinants of renal autoregulation in circulatory shock, including the influence of comorbidities and the effects of vasopressor treatment. We review published studies on renal autoregulation relevant to the management of acutely ill patients with shock...

It is essential to understand the pathophysiology of cardiogenic shock and the possible deterioration of contractile function during high-risk PCI in order to select those patients who could benefit from mechanical support thus choosing the most suitable device in every situation. Percutaneous Ventricular Assist Devices (pVAD) provide hemodynamic support by improving cardiac output and mean arterial pressure, but their specific features result in different hemodynamic effects and degrees of myocardial ischemic protection and LV unloading...

Overdose of cardiovascular medications such as beta blockers and calcium channel blockers cause impaired cardiac contractility, vasoplegia, and/or rhythm disturbances. In addition to conventional management of limiting absorption, increasing elimination and hemodynamic support intravenous (IV) calcium infusion, hyperinsulinemia-euglycemia therapy, glucagon infusion, and IV lipid emulsion have been tried. Extracorporeal circulatory assist device support has been reported as a rescue therapy in overdose refractory to maximal medical therapy...

NEW FINDINGS: What is the central question of this study? Collagen-binding β1 -integrins function physiologically in cellular control of dermal interstitial fluid pressure (PIF ) in vivo and thereby participate in control of extravascular fluid volume. During anaphylaxis, simulated by injection of Compound 48/80 integrin αV β3 takes over this physiological function. Here we addressed the question whether integrin αV β3 can replace collagen-binding β1 -integrin to maintain a long-term homeostatic PIF ...

BACKGROUND AND OBJECTIVES: In severe circulatory failure agreement between arterial and mixed venous or central venous values is poor; venous values are more reflective of tissue acid-base imbalance. No prior study has examined the relationship between peripheral venous blood gas (VBG) values and arterial blood gas (ABG) values in hemodynamic compromise. The objective of this study was to examine the correlation between hemodynamic parameters, specifically systolic blood pressure (SBP) and the arterial-peripheral venous (A-PV) difference for all commonly used acid-base parameters (pH, Pco2 , and bicarbonate)...

BACKGROUND: Right ventricular (RV) failure due to pulmonary embolism (PE) increases morbidity and mortality and contributes to prolonged hospital length of stay and higher costs of care. RV mechanical circulatory support (MCS) including Impella RP devices have been increasingly used in hemodynamically compromised PE patients who are refractory to intravascular volume expansion and inotropic therapy. However, effectiveness and safety of Impella RP, in hemodynamically unstable PE patients is unknown...
