Comparative StudyThe Present State of Neurointensivist Training in the United States: A Comparison to Other Critical Care Training Programs.
This manuscript describes the state of neurocritical care fellowship training, compares its written standards to those of other critical care fellowship programs, and discusses how programmatic oversight by the United Council for Neurological Subspecialties should evolve to meet American College of Graduate Medical Education standards. This review is a work product of the Society of Critical Care Medicine Neuroscience section and was reviewed and approved by the Council of the Society of Critical Care Medicine. ⋯ The United Council for Neurologic Subspecialties has developed a directed program development strategy to emulate American College of Graduate Medical Education standards with the goal to have standards that are similar or identical to American College of Graduate Medical Education standards.

To determine whether contemporary β-lactam anti-infective dosing recommendations in critically ill children achieve concentrations associated with maximal anti-infective activity. The secondary objective was to describe the microbiological and clinical outcomes associated with β-lactam therapeutic drug management. ⋯ Overall, 95% of patients had subtherapeutic anti-infective concentrations and did not achieve the requisite pharmacodynamic exposure with current pediatric dosing recommendations. All patients achieved a microbiological response, and 95.7% achieved clinical response with active β-lactam therapeutic drug management. These data suggest β-lactam therapeutic drug management is a potentially valuable intervention to optimize anti-infective pharmacokinetics and the pharmacodynamic exposure. Further, these data also suggest the need for additional research in specific pediatric populations and assessing clinical outcomes associated with β-lactam therapeutic drug management in a larger cohort of pediatric patients.

Numeracy and Interpretation of Prognostic Estimates in Intracerebral Hemorrhage Among Surrogate Decision Makers in the Neurologic ICU.
Clinicians caring for patients with intracerebral hemorrhage must often discuss prognosis and goals of care with their patients' surrogate decision makers, and may make numeric estimates of likelihood of survival and functional independence, informed by validated prediction models. Surrogates' prognostic estimates are often discordant with physicians', suggesting that physicians' numeric statements may not be accurately interpreted. We sought to assess the relationship between numeracy and interpretation of prognostic estimates in intracerebral hemorrhage among surrogate decision makers. We also assessed surrogates' application of prognostic estimates to decisions regarding goals of care. ⋯ Poor numeracy is common among surrogate decision makers in an intensive care setting and poses a barrier to communication between surrogates and clinicians regarding prognosis and goals of care.

Renal Decapsulation Prevents Intrinsic Renal Compartment Syndrome in Ischemia-Reperfusion-Induced Acute Kidney Injury: A Physiologic Approach.
Acute kidney injury is a serious complication with unacceptably high mortality that lacks of specific curative treatment. Therapies focusing on the hydraulic behavior have shown promising results in preventing structural and functional renal impairment, but the underlying mechanisms remain understudied. Our goal is to assess the effects of renal decapsulation on regional hemodynamics, oxygenation, and perfusion in an ischemic acute kidney injury experimental model. ⋯ Our results strongly suggest that renal decapsulation prevents the onset of an intrinsic renal compartment syndrome after ischemic acute kidney injury.

Mesenchymal Stem Cells From Bone Marrow, Adipose Tissue, and Lung Tissue Differentially Mitigate Lung and Distal Organ Damage in Experimental Acute Respiratory Distress Syndrome.
Mesenchymal stem cells-based therapies have shown promising effects in experimental acute respiratory distress syndrome. Different mesenchymal stem cells sources may result in diverse effects in respiratory diseases; however, there is no information regarding the best source of mesenchymal stem cells to treat pulmonary acute respiratory distress syndrome. We tested the hypothesis that mesenchymal stem cells derived from bone marrow, adipose tissue, and lung tissue would lead to different beneficial effects on lung and distal organ damage in experimental pulmonary acute respiratory distress syndrome. ⋯ Mesenchymal stem cells from different sources led to variable responses in lungs and distal organs. Bone marrow and adipose tissue mesenchymal stem cells yielded greater beneficial effects than lung tissue mesenchymal stem cells. These findings may be regarded as promising in clinical trials.
