Background: The Society for Cardiovascular Angiography and Intervention (SCAI) Shock Classification can define shock severity. We evaluated the vasoactive-inotropic score (VIS) combined with the SCAI Shock Classification for mortality risk stratification. Methods: This was a single-center retrospective cohort analysis including Mayo Clinic cardiac intensive care unit patients from 2007 to 2015. ⋯ A gradient of in-hospital mortality was observed according to the VIS at 1 h and the increase in VIS from 1 to 24 h. Conclusions: Higher vasoactive drug requirements portend a higher risk of mortality, particularly a high VIS early after admission. The VIS provides incremental prognostic information beyond the SCAI Shock Classification, emphasizing the continuum of risk that exists across the spectrum of shock severity.

Observational StudyImmune Profiling Panel Gene Set Identifies Critically Ill Patients With Low Monocyte Human Leukocyte Antigen-DR Expression: Preliminary Results From the REAnimation Low Immune Status Marker (REALISM) Study.
There is a crucial unmet need for biomarker-guided diagnostic and prognostic enrichment in clinical trials evaluating immune modulating therapies in critically ill patients. Low monocyte expression of human leukocyte antigen-DR (mHLA-DR), considered as a reference surrogate to identify immunosuppressed patients, has been proposed for patient stratification in immunostimulation approaches. However, its widespread use in clinic has been somewhat hampered by technical constraints inherent to flow cytometry technology. The objective of the present study was to evaluate the ability of a prototype multiplex polymerase chain reaction tool (immune profiling panel [IPP]) to identify immunosuppressed ICU patients characterized by a low mHLA-DR expression. ⋯ This study reports on the potential of the IPP gene set to identify ICU patients presenting with mHLA-DR less than 8,000 AB/C. Upon further optimization and validation, this molecular tool may help in the stratification of patients that could benefit from immunostimulation in the context of personalized medicine.

The Association Between Central Line-Associated Bloodstream Infection and Central Line Access.
Identifying modifiable risk factors associated with central line-associated bloodstream infections (CLABSIs) may lead to modifications to central line (CL) management. We hypothesize that the number of CL accesses per day is associated with an increased risk for CLABSI and that a significant fraction of CL access may be substituted with non-CL routes. ⋯ The number of daily CL accesses is independently associated with risk of CLABSI in the next 3 days. In the pediatric population examined, most medications delivered through CLs could be safely administered peripherally. Efforts to reduce CL access may be an important strategy to include in contemporary CLABSI-prevention bundles.

Sepsis is one of the leading causes of morbidity and mortality worldwide. Monocytes seem to undergo functional reprogramming during sepsis, resulting in dysregulated host immune response. To clarify this dysregulation mechanism, we investigated three histone modifications found in promoters of genes involved in innate immune response, and associated these findings with gene transcription in septic patients. ⋯ In addition, we found moderate to strong correlation between gene transcription and the enzymes that modulate these histone modifications in the transcriptome data sets. Our study, one of the pioneering by evaluating septic patients' samples, suggests that epigenetic enzymes modulate the prevalent histone marks in promoters of genes involved in the immune-inflammatory response, altering the transcription of these specific genes during sepsis. Furthermore, nonsurviving sepsis patients have a more pronounced epigenetic dysregulation compared with survivors, suggesting a more dysfunctional response.

Successful anesthetics occur when safe, effective perioperative care is coupled with patient satisfaction. We present the case of a 63-year-old woman with advanced Parkinson's disease who presented for a deep brain stimulation (DBS) device battery change under monitored anesthesia care (MAC). While MAC is commonly utilized for a DBS battery change, our patient reported previously experiencing intraoperative pain, anxiety, and the inability to communicate discomfort under MAC, leading to posttraumatic stress disorder. This case report highlights the importance of preoperative informed consent, discussion of patient expectations, and proactive planning for intraoperative communication strategies when MAC is the chosen method.
