Plasma Renin Concentration is Associated With Hemodynamic Deficiency and Adverse Renal Outcome in Septic Shock.

Background: In septic shock, both systemic vasodilatation and glomerular arteriole dilatation are responsible for the drop in glomerular filtration observed in early acute kidney injury. Angiotensin II has been shown to act on both mechanisms. Our objective was to evaluate the impact of renin angiotensin system activation, on hemodynamic deficiency and renal outcome in patient with septic shock and to assess whether urinary sodium could be a reliable test for high plasma renin concentration screening.

Percutaneous ultrasound-guided balloon-assisted embolization of iatrogenic femoral artery pseudoaneurysms with Glubran2 cyanoacrylate glue: safety, efficacy and outcomes.

Background: Femoral pseudoaneurysm (PA) is a frequent complication of arterial access for endovascular procedures. Surgery has traditionally been considered as the gold standard of therapy. We aimed to report our experience of percutaneous ultrasound (US)-guided balloon-assisted embolization with cyanoacrylate glue for the treatment of iatrogenic femoral PAs.

End-of-life situations in cardiology: a qualitative study of physicians' and nurses' experience in a large university hospital.

Background: Professional societies call for integration of end-of-life discussions early in the trajectory of heart failure, yet it remains unclear where current practices stand in relation to these recommendations. We sought to describe the perceptions and attitudes of caregivers in cardiology regarding end-of-life situations.

Methods: We performed a qualitative study using semi-directive interviews in the cardiology department of a university teaching hospital in France.

Actinomycosis: An infrequent disease in renal transplant recipients?

Actinomycosis is a rare and heterogeneous infection involving Gram-positive anaerobic bacteria, which are commensals in the oral cavity and digestive tract. Only four cases of actinomycosis in renal transplant recipients have been reported to date. We performed a retrospective study in French renal transplantation centers to collect data about actinomycosis, patients, and transplantation.

Epinephrine Versus Norepinephrine for Cardiogenic Shock After Acute Myocardial Infarction.

Background: Vasopressor agents could have certain specific effects in patients with cardiogenic shock (CS) after myocardial infarction, which may influence outcome. Although norepinephrine and epinephrine are currently the most commonly used agents, no randomized trial has compared their effects, and intervention data are lacking.

Objectives: The goal of this paper was to compare in a prospective, double-blind, multicenter, randomized study, the efficacy and safety of epinephrine and norepinephrine in patients with CS after acute myocardial infarction.

Persistence of gastric or esophageal varices on final angiography increases transjugular intrahepatic portosystemic shunt revision rate after polytetrafluoroethylene-covered stent shunt creation.

Background: To assess the association between final polytetrafluoroethylene (PTFE)-covered stent transjugular intrahepatic portosystemic shunt (TIPS) angiographic parameters and free shunt revision survey.

Methods: Series of two comparison groups were generated with persistence of varices or not, the 25, 50, and 75 percentile as cutoff for each angle and a 15-mm distance as cutoff for distance D. Kaplan Meier free shunt revision curves were then created and compared with Log Rank test.

What are the ethical questions raised by the integration of intensive care into advance care planning?

A major goal of intensive care units (ICUs) is to offer optimal management, but for many patients admitted to the ICU, they are unlikely to yield any lasting benefit. In this context, the ICU physician remains a key intermediary, particularly when a decision regarding possible limitation or withdrawal of life-sustaining therapy becomes necessary. The possibility of admission to the ICU, and the type of care the patient would like to receive there, should be integrated into the healthcare project in agreement with the patient, regardless of the stage of disease that the patient suffers from.

Can qualitative research play a role in answering ethical questions in intensive care?

Scientific and technological progress, as well as increased patient autonomy have profoundly changed the world of healthcare, giving rise to new situations that are increasingly complex and uncertain. Quantitative paradigms, of which the main bastion is evidence-based medicine (EBM), are beginning to reach their limits in daily routine practice of medicine, and new approaches are emerging that can provide novel heuristic perspectives. Qualitative research approaches can be useful for apprehending new areas of knowledge that are fundamental to recent and future developments in intensive care.

What are the ethical aspects surrounding the collegial decisional process in limiting and withdrawing treatment in intensive care?

The decision to limit or withdraw life-support treatment is an integral part of the job of a physician working in the intensive care unit, and of the approach to care. However, this decision is influenced by a number of factors. It is widely accepted that a medical decision that will ultimate lead to end-of-life in the intensive care unit (ICU) must be shared between all those involved in the care process, and should give precedence to the patient's wishes (either directly expressed by the patient or in written form, such as advance directives), and taking into account the opinion of the patient's family, including the surrogate if the patient is no longer capable of expressing themselves.

Ethical challenges involved in obtaining consent for research from patients hospitalized in the intensive care unit.

Clinical research remains a vital contributor to medical knowledge, and is an established and integral part of the practice of medicine worldwide. Respect for patient autonomy and ethical principles dictate that informed consent must be obtained from subjects before they can be enrolled into clinical research, yet these conditions may be difficult to apply in real practice in the intensive care unit (ICU). A number of factors serve to complexify the consent process in critically ill patients, notably decisional incapacity of the patient due to illness or sedation.

What are the ethical issues in relation to the role of the family in intensive care?

A large proportion of patients admitted to the intensive care unit (ICU) are unable to express themselves, often due to acute illness, shock or trauma, and this precludes any communication and/or consent for care that might reflect their wishes and opinions. In such cases, the only solution for the ICU physician is to include the patient's family in the healthcare decisions. This can represent a significant burden on the family, on top of the psychological distress of the ICU environment and hospitalisation of their relatives, and many family members may suffer from anxiety, depression or symptoms of post-traumatic stress disorder (PTSD) during or after the hospitalisation and/or death of a loved one in the ICU.

Intersecting vulnerabilities in professionals and patients in intensive care.

In the context of healthcare delivery, the vulnerabilities of patients in the intensive care unit (ICU) are intricately linked with those experienced on a daily basis by caregivers in the ICU in a symbiotic relation, whereby patients who are suffering can in turn engender suffering in the caregivers. In the same way, caregivers who are suffering themselves may be a source of suffering for their patients. The vulnerabilities of both patients and caregivers in the ICU are simultaneously constituted through a process that is influenced on the one hand by the healthcare objectives of the ICU, and on the other hand, by the conformity of the patients who are managed in that ICU.

Ethical aspects of admission or non-admission to the intensive care unit.

The question of admission and non-admission to the intensive care unit (ICU) raises several ethical questions. There is a fine line between the risk of loss-of-opportunity for the patient in case of non-admission, and the risk of unreasonable therapeutic obstinacy, in case of unjustified admission. Similar difficulties arise in decisions regarding re-admission or non-re-admission, with the sole difference that the intensivists already know the patient and his/her medical history.

Sucrose octasulfate dressing versus control dressing in patients with neuroischaemic diabetic foot ulcers (Explorer): an international, multicentre, double-blind, randomised, controlled trial.

Background: Diabetic foot ulcers are serious and challenging wounds associated with high risk of infection and lower-limb amputation. Ulcers are deemed neuroischaemic if peripheral neuropathy and peripheral artery disease are both present. No satisfactory treatment for neuroischaemic ulcers currently exists, and no evidence supports one particular dressing.

The ICU-Diary study: prospective, multicenter comparative study of the impact of an ICU diary on the wellbeing of patients and families in French ICUs.

Background: Post-intensive care syndrome includes the multiple consequences of an intensive care unit (ICU) stay for patients and families. It has become a new challenge for intensivists. Prevention programs have been disappointing, except for ICU diaries, which report the patient's story in the ICU.

Enteral versus parenteral early nutrition in ventilated adults with shock: a randomised, controlled, multicentre, open-label, parallel-group study (NUTRIREA-2).

Background: Whether the route of early feeding affects outcomes of patients with severe critical illnesses is controversial. We hypothesised that outcomes were better with early first-line enteral nutrition than with early first-line parenteral nutrition.

Methods: In this randomised, controlled, multicentre, open-label, parallel-group study (NUTRIREA-2 trial) done at 44 French intensive-care units (ICUs), adults (18 years or older) receiving invasive mechanical ventilation and vasopressor support for shock were randomly assigned (1:1) to either parenteral nutrition or enteral nutrition, both targeting normocaloric goals (20-25 kcal/kg per day), within 24 h after intubation.
