Stereotactic minimally invasive surgery (sMIS) has been used in the treatment of intracerebral hemorrhage (ICH) in recent years and has obtained promising results. However, the outcomes of patients are associated with many factors. The aim of the present study was to retrospectively observe the relationship between hematoma shape features and the outcome of patients with spontaneous ICH following sMIS. ⋯ Patients with regular-shaped hematomas exhibited more favorable outcomes. Irregular-shaped hematomas and postoperative residual hematoma volume predicted a poor outcome in patients with ICH following sMIS.

Catheter-associated urinary tract infections (CAUTIs) account for 25% of all hospital-acquired infections. Neuro-critically ill patients are at 2-5 times greater risk of developing CAUTI because of increased use of indwelling urinary catheters due to neurogenic urinary retention. Despite the heightened risk of CAUTI occurrence for the neuro-critically ill, there is little data on specific characteristics of CAUTIs and risk factors among this population. The aim of this study was to identify characteristics and risk factors associated with CAUTI development in the neuro-critical patient population. ⋯ Stool incontinence, older age, female sex, longer neuroICU LOS and presence of comorbidities such as HTN and diabetes were associated with CAUTI development in the neuro-critically ill population. Average Time-to-CAUTI after catheter placement was 6 days with earlier occurrence if more frequent catheterizations. Colonization of urinary catheters without infection might contribute to CAUTI diagnosis. Prospective research is needed to determine impact of prevention protocols incorporating these factors.

Neurovascular-based imaging techniques such as functional MRI (fMRI) may reveal signs of consciousness in clinically unresponsive patients but are often subject to logistical challenges in the intensive care unit (ICU). Near-infrared spectroscopy (NIRS) is another neurovascular imaging technique but low cost, can be performed serially at the bedside, and may be combined with electroencephalography (EEG), which are important advantages compared to fMRI. Combined NIRS-EEG, however, has never been evaluated for the assessment of neurovascular coupling and consciousness in acute brain injury. ⋯ We suggest that NIRS-EEG for monitoring of acute brain injury in the ICU is worthy of further exploration. Normalization of neurovascular coupling may herald recovery of consciousness after acute brain injury.

Observational Study
High Serum Levels of Caspase-3 and Early Mortality in Patients with Severe Spontaneous Intracerebral Hemorrhage.
Apoptotic cell death leads to secondary brain injury after spontaneous intracerebral hemorrhage (SIH). There is an association between serum caspase-3 levels and late mortality (at 6 months) in patients with SIH in basal ganglia. The new objective of this study was to determine whether there exists an association between serum caspase-3 levels and early mortality (at 30 days) in patients with SIH at different sites and not only in basal ganglia. ⋯ The new findings of our study are that serum caspase-3 levels are associated with early mortality in patients with severe supratentorial SIH at different sites and that those levels during the first week of SIH are higher in non-survivors than in survivors.

Infection and venous thromboembolism (VTE) are associated with worse outcomes after intracerebral hemorrhage (ICH). The relationship between infection and VTE in ICH patients is unclear. We hypothesized that infection would be associated with subsequent VTE after ICH. ⋯ Infections are associated with subsequent risk of VTE among patients with ICH. Further investigation is required to elucidate mechanisms behind this association and to improve VTE prevention after ICH.
