Enterococci are a major cause of bloodstream infections in hospitalized patients and have limited antimicrobial treatment options due to their many resistance mechanisms. Molecular technologies have significantly shortened the time to enterococcal isolate identification compared with conventional methods. We evaluated the impact of rapid organism(More)
Microfluidics applications can benefit from a dry film approach in multiple ways – particularly in the preparation of multi-layer, multi-level fluidic channels and structures on patternable substrates and covers [1,2,3,4]. Of special benefit is the extreme simplicity in the use of the dry film sheets. A standard lamination approach allows one to apply the(More)
SUEX epoxy Thick Dry Film Sheets (TDFS) are a promising material for a wide range of MEMS applications. They contain a cationically cured modified epoxy formulation utilizing an antimony-free photo acid generator (PAG). A highly controlled solvent-less process provides uniform resist coatings between two throw-away layers of protective polyester (PET) film(More)
PURPOSE Critically ill patients who develop sepsis may be at a higher risk of venous thromboembolism (VTE) prophylaxis failure; however, studies in this population are limited. The objective of this study was to identify the incidence of VTE prophylaxis failure in this population. METHODS This retrospective review of patients admitted to the intensive(More)
BACKGROUND With a growing obesity epidemic, the approach to care of this patient remains controversial and in many circumstances different than the general population. Appropriate hemodynamic support, although still controversial, remains a cornerstone of septic shock therapy. Catecholamines are currently recommended by guidelines without a preferred dosing(More)
PURPOSE The purpose of this study was to identify risk factors associated with inappropriate continuation of neuroleptics postdischarge from the intensive care unit (ICU) and hospital. MATERIALS AND METHODS A retrospective chart review was performed including all patients greater than 18 years of age who received neuroleptic medications in an ICU. (More)
Acute respiratory distress syndrome (ARDS) is a syndrome of acute lung injury that is characterized by noncardiogenic pulmonary edema and severe hypoxemia second to a pathogenic impairment of gas exchange. Despite significant advances in the area, mortality remains high among ARDS patients. High mortality and a limited spectrum of therapeutic options have(More)
BACKGROUND Patients in intensive care units (ICUs) may be placed on contact isolation for meticillin-resistant Staphylococcus aureus (MRSA) colonization to prevent transmission. Prior studies suggest that isolated patients may receive substandard care compared with non-isolated patients. An optimal level of sedation is required to facilitate mechanical(More)
