Mindfulness and Coping Are Inversely Related to Psychiatric Symptoms in Patients and Informal Caregivers in the Neuroscience ICU: Implications for Clinical Care.
To assess the correlation of psychosocial resiliency factors (mindfulness and coping) with symptoms of posttraumatic stress, anxiety, and depression in patients recently admitted to the neuroscience ICU and their primary informal caregivers. ⋯ Rates of clinically significant psychiatric symptoms were high, equally prevalent in patients and caregivers, and interdependent between patients and their caregivers. For both patients and caregivers, psychological resiliency factors were associated with both self and partner psychiatric symptoms. Findings suggest that attending to the psychiatric health of both patients and caregivers in the neuroscience ICU is a priority and that patients and their caregivers must be considered together in a system to fully address either individual's psychiatric symptoms.

Observational StudyThe Use of Ferritin to Identify Critically Ill Patients With Secondary Hemophagocytic Lymphohistiocytosis.
Thrombocytopenia is a common, multifactorial, finding in ICU. Hemophagocytosis is one of the main explanatory mechanisms, possibly integrated into hemophagocytic lymphohistiocytosis syndrome, of infectious origin in the majority of cases in ICU. The hemophagocytic lymphohistiocytosis is probably underdiagnosed in the ICU, although it is associated with dramatic outcomes. The main objectives of this work were to identify the frequency of secondary hemophagocytic lymphohistiocytosis, and the main prognostic factors for mortality. ⋯ Hemophagocytosis is common in thrombocytopenic patients with sepsis, frequently included in a postinfectious hemophagocytic lymphohistiocytosis setting. Our study reveals that ferritin could be a reliable prognostic marker in these patients, and hold particular interest in discussing a specific treatment for hemophagocytic lymphohistiocytosis.

Validity of Different Delirium Assessment Tools for Critically Ill Children: Covariates Matter.
To evaluate test validity of the Pediatric Confusion Assessment Method for the ICU, the Pediatric Anesthesia Emergence Delirium scale, and the newly developed severity scale for the Pediatric Confusion Assessment Method for the ICU; to prospectively assess covariates and their influence on test validity of the scores. ⋯ The severity scale for the Pediatric Confusion Assessment Method for the ICU showed the best test validity when used in critically ill children of 5 years old or older. Nevertheless, validity of delirium screening itself depends on patient specific factors. These factors should be taken into consideration when choosing a delirium screening instrument.

Case ReportsPeripheral IV Insulin Infusion Infiltration Presenting as "Insulin Resistance".
We present the case of a 66-year-old woman who developed hypoglycemia following the prolonged infiltration of a high dose continuous peripheral IV insulin infusion. ⋯ Peripheral IV insulin infusion infiltration should be considered when patients do not respond to increasing rates of insulin infusion.

4-Aminopyridine, A Blocker of Voltage-Dependent K+ Channels, Restores Blood Pressure and Improves Survival in the Wistar Rat Model of Anaphylactic Shock.
Anaphylactic shock is associated with severe hypotension. Potassium channel blockers, such as 4-aminopyridine, induce vasoconstriction. The objective of this study was to test the ability of 4-aminopyridine to restore blood pressure and increase survival in anaphylactic shock. ⋯ Our data suggest that voltage-dependent K+ channel inhibition with 4-aminopyridine treatment restores blood pressure and increases survival in the Wistar rat model of anaphylactic shock. 4-aminopyridine or related voltage-dependent K channel blockers could be a useful additional therapeutic approach to treatment of refractory anaphylactic shock.
