An appreciation of the post-ICU burden for family members, as well as the ways to prevent and minimize their symptoms of stress, anxiety, and depression. ⋯ A high proportion of family members present with symptoms of anxiety (70%) and depression (35%). Acute stress disorder and posttraumatic stress disorder (PTSD) related symptoms are also common. These symptoms are significantly more frequent when the relative is a spouse, or in bereaved family members. Few long-term data are available. However, in family members of dying patients, 1 year after the loss, up to 40% of them present with criteria for psychiatric illness such as generalized anxiety, major depressive disorders, or complicated grief. Prevention of post-ICU burden, mostly based on communication strategies, has been proposed to assist relatives.

ReviewInterventions to decrease the morbidity and mortality associated with implantable cardioverter-defibrillator shocks.
Implantable cardioverter-defibrillator (ICD) implantation is the standard of care for secondary prevention in patients with previous cardiac arrest and for primary prevention in appropriately selected patients with cardiomyopathy. However, ICD therapies and the arrhythmias that trigger these therapies cause decreased quality of life as well as increased morbidity and mortality. In this review, we summarize the recent evidence for interventions that may prevent ICD therapies. ⋯ Pharmacologic therapy and appropriate device programming remain essential to the overall care of ICD patients. The role of CRT continues to grow as we gain a better understanding of its benefits. Advancements in the fields of catheter ablation and new understanding of the autonomic nervous system's effects on ventricular arrhythmias allow interventions to decrease the frequency of ICD shocks.

ReviewSevere acute respiratory infections in the postpandemic era of H1N1.
Shortly after the advent of severe acute respiratory syndrome and the avian influenza, the emergence of the influenza A(H1N1)2009 pandemic caused significant vibrations to the public health authorities and stressed the health systems worldwide. We sought to investigate whether this experience has altered our knowledge and our current and future practice on the management of severe acute respiratory infections (SARI) and community-acquired pneumonia. ⋯ The recent influenza A(H1N1)2009 pandemic has highlighted our weaknesses relating to the diagnosis and assessment of severity of SARI, compromising early treatment and ultimate outcomes; further research based on this experience will help to improve prognosis and boost our future preparedness. An important message is the necessity of international collaboration for the rapid dissemination of locally acquired knowledge.

Acute ST-elevation myocardial infarction (STEMI) is a major cause of morbidity, mortality, and disability. This review summarizes recent advances in the treatment of patients with STEMI. ⋯ Primary PCI with stent implantation as soon as possible is the best treatment strategy for patients with STEMI. Aspirin, bivalirudin, and either prasugrel or ticagrelor are the best antithrombotic agents to support primary PCI. Thrombus aspiration and intra-aortic balloon counterpulsation are important device adjuncts. Systemic hypothermia appears to be an important advance for survivors of cardiac arrest with anoxic encephalopathy, but the benefits of stem cell therapy have yet to be proven.

ReviewHeart rescue: the role of mechanical circulatory support in the management of severe refractory cardiogenic shock.
Cardiogenic shock is present in 3.5% of patients presenting with acute decompensated heart failure. Despite advances in therapy, mortality remains high, approaching 70% in some settings. Recent management strategies have incorporated the use of mechanical circulatory support (MCS), which has been associated with better survival in nonrandomized trials. MCS is increasingly used in the acute setting and has become an important treatment modality for cardiogenic shock. ⋯ This article will review novel strategies in the management of cardiogenic shock including percutaneous MCS (intra-aortic balloon pump, Impella, TandemHeart, venoarterial extracorporeal membrane oxygenation) and surgically implanted devices (CentriMag) that are used for short-term management. We will review the mechanisms involved in cardiogenic shock and discuss management and device selection strategies.
