Controlling patient temperature is important for a wide variety of clinical conditions. Cooling to normal or below normal body temperature is often performed for neuroprotection after ischemic insult (e.g. hemorrhagic stroke, subarachnoid hemorrhage, cardiac arrest, or other hypoxic injury). Cooling from febrile states treats fever and reduces the negative effects of hyperthermia on injured neurons. Patients are warmed in the operating room to prevent inadvertent perioperative hypothermia, which is known to cause increased blood loss, wound infections, and myocardial injury, while also prolonging recovery time...

Left ventricular assist devices (LVADs) improve survival in patients with advanced heart failure. As LVAD use increases, so do the number of patients with LVADs who also have kidney disease. However, there are only sparse data on how best to care for these patients. This review provides an overview of LVAD principles and indications, including blood pressure assessment and criteria for receipt of both destination and bridge to transplantation LVADs. Following LVAD implantation, kidney function may improve in the short term, particularly if cardiorenal physiology was present; in the longer term, data remain limited...

BACKGROUND: Self-expanding nitinol stents must be oversized at least by a minimal amount to ensure contact with the vessel wall and prevent migration. Once the stent is deployed it exerts a continuous force upon the vascular wall, termed chronic outward force (COF). Animal studies have found an increased neointimal hyperplasia in stents with high oversizing and thus high COF. Data about correlation between COF and neointimal hyperplasia in humans are currently lacking. The objective of the BIOFLEX-COF trial is to prospectively investigate differences in formation of intimal hyperplasia at 1 and 2 years after implantation of nitinol stents with high versus low COF in de novo femoropopliteal occlusive arterial lesions...

REVIEW
Wee-Song Yeo, Qin Xiang Ng
End-stage kidney disease (ESKD), one of the most prevalent diseases in the world and with increasing incidence, is associated with significant morbidity and mortality. Current available modes of renal replacement therapy (RRT) include dialysis and renal transplantation. Though renal transplantation is the preferred and ideal mode of RRT, this modality may not be available to all patients with ESKD. Moreover, renal transplant recipients are constantly at risk of complications associated with immunosuppression and immunosuppressant use, and posttransplant lymphoproliferative disorder...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) using a self-expanding valve has been shown to be superior to an open operation in high-risk patients. Extensive iliofemoral peripheral vascular disease can prohibit femoral access. In these cases, direct aortic (DA) implantation may be a suitable option. METHODS: The current analysis compared outcomes in patients undergoing TAVR with the self-expanding CoreValve prosthesis (Medtronic, Minneapolis, MN) by direct aortic (DA) access vs iliofemoral (IF) access...

As the result of requests from several state boards of nursing, the Infusion Nurses Society (INS) convened a task force to determine whether insertion of central vascular access devices by appropriately trained registered nurses (RNs) should be recommended. The task force consisted of RNs and advanced practice registered nurses with infusion therapy experience in various practice settings. The results are presented in INS' newest position paper, adopted by the INS Board of Directors, September 2017.

Aortic stenosis is a common valvular condition with increasing prevalence in aging populations. When severe and symptomatic, the downstream prognosis is poor without surgical or transcatheter aortic valve replacement. Transcatheter aortic valve replacement is now considered a viable alternative to surgical aortic valve replacement in patients considered high and intermediate risk for surgery. Pre-intervention imaging with echocardiography and CT are essential for procedure planning and device selection to help optimize clinical outcomes with MR angiography playing largely a complementary role...
