BACKGROUND: Postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) may complicate a patient's postoperative recovery in several ways. Monitoring of processed electroencephalogram (EEG) or evoked potential (EP) indices may prevent or minimize POD and POCD, probably through optimization of anaesthetic doses. OBJECTIVES: To assess whether the use of processed EEG or auditory evoked potential (AEP) indices (bispectral index (BIS), narcotrend index, cerebral state index, state entropy and response entropy, patient state index, index of consciousness, A-line autoregressive index, and auditory evoked potentials (AEP index)) as guides to anaesthetic delivery can reduce the risk of POD and POCD in non-cardiac surgical or non-neurosurgical adult patients undergoing general anaesthesia compared with standard practice where only clinical signs are used...

Objective: To evaluate the therapeutic potential of bortezomib, a proteasome inhibitor that target plasma cells, in order to revive stalled recovery in patients with anti- N -methyl-d-aspartate (NMDA) receptor encephalitis who remain bedridden even after aggressive immunotherapy. Methods: We consecutively enrolled patients with anti-NMDA receptor encephalitis who remained bedridden after first-line immunotherapy (steroids and intravenous immunoglobulin), second-line immunotherapy (rituximab), and tocilizumab treatment, and treated them with subcutaneous bortezomib...

BACKGROUND: Patients with chronic disorders of consciousness face a significant lack of treatment options. OBJECTIVE: We aimed at investigating the feasibility and the behavioral effects of home-based transcranial direct current stimulation (tDCS), applied by relatives or caregivers, in chronic patients in minimally conscious state (MCS). METHODS: Each participant received, in a randomized order, 20 sessions of active and 20 sessions of sham tDCS applied over the prefrontal cortex for 4 weeks; separated by 8 weeks of washout...

Objective: Severe thermal injury induces metabolic and physiological stress, prompting a disruption in the hypothalamic-pituitary-adrenal axis. The objective of this study was to evaluate potential confounding effects of Lactated Ringer's (LR) resuscitation on adrenal damage and cortisol production following burn. Methods: Anesthetized swine were instrumented with jugular catheters and sustained 40% TBSA burns from brass probes heated to 100ºC. Animals recovered to consciousness and received IV fluid resuscitation with LR at two different volumes: 15 mL/kg/day (Limited Volume; LV, n=6) or 2 mL/kg/%TBSA/day (Modified Brooke; MB, n=6)...

Self-report measures of sexuality may be influenced by people's conscious concerns about confidentiality and social desirability. Alternatively, non-conscious measures (e.g., implicit association tests; IATs) are designed to minimize these validity concerns. We constructed an IAT measure of sex guilt using 154 male and female university students. The sex guilt IAT demonstrated convergent validity as it correlated with various sexual behaviors and incremental validity as it improved the prediction of several sexual behaviors beyond that provided by the Mosher sex guilt scale...

STUDY OBJECTIVE: Two clinical decision rules, the Canadian CT Head Rule and the New Orleans Criteria, set the standard to guide clinicians in determining which patients with minor head trauma need computed tomography (CT) imaging. Both rules were derived with patients with minor head injury who had had a loss of consciousness or witnessed disorientation. No evidence exists for evaluating patients and need for CT imaging with minimal head injury; that is, patients who had a head injury but no loss of consciousness or disorientation and therefore would have been excluded from the Canadian CT Head Rule and New Orleans Criteria trials...

Modeling and simulations have gained a leading position in contemporary attempts to describe, explain, and quantitatively predict the human brain's operations. Computer models are highly sophisticated tools developed to achieve an integrated knowledge of the brain with the aim of overcoming the actual fragmentation resulting from different neuroscientific approaches. In this paper we investigate the plausibility of simulation technologies for emulation of consciousness and the potential clinical impact of large-scale brain simulation on the assessment and care of disorders of consciousness (DOCs), e...

BACKGROUND AND PURPOSE: The GOLIATH trial (General or Local Anesthesia in Intra-Arterial Therapy) compared infarct growth and outcome in patients undergoing endovascular therapy under either general anesthesia or conscious sedation. Magnetic resonance imaging was performed before and after the procedure to study infarct growth. In this post hoc analysis of GOLIATH, we aimed to characterize the workflow of patients undergoing magnetic resonance imaging selection before endovascular therapy...

OBJECTIVE: The management of patients with disorders of consciousness (DOC) has raised several important ethical, social, and medical issues. It is also known that families and caregivers are subjected to physical and emotional load due to their assistance activity. The aim of this observational study was to compare distress and coping strategies used among caregivers of two kinds of DOC: vegetative state (VS) and minimally conscious state (MCS). METHODS: We have enrolled 80 caregivers (mean age 47...

RATIONALE: Basal ganglia hematomas resulting from the rupture of aneurysms of the distal middle cerebral artery (MCA) are extremely rare and are usually treated by craniotomy. To date, only 5 cases of MCA aneurysm have been treated using neuroendoscopy, and none of these cases involved hematomas. For the first time, we report a special case in which neuroendoscopy was used to evacuate a hematoma and clip an aneurysm at the same time. PATIENT CONCERNS: A massive basal ganglia hematoma in a 60-year-old man was evacuated using neuroendoscopy, and a distal MCA aneurysm was discovered and clipped successfully under the neuroendoscopy during the operation...

RATIONALE: Life-threatening anaphylactic shock is a rare (1 in 1 million) but documented occurrence in response to subcutaneous immunotherapy. Immediate administration of Epinephrine (Epi) is critical to save lives in these situations. The current protocol for systemic reactions in immunotherapy is for the prescribing physician to reassess the dosing and schedule as well as the risk:benefit assessment for the therapy and determine whether or not to proceed. PATIENT CONCERNS: The patient revealed concerns regarding the neurologic sequela sustained after undergoinig life-threatening anaphylactic shock...

The reliable assessment and management of avian pain is important in the context of animal welfare. Overtly expressed signs of pain vary substantially between and within species, strains and individuals, limiting the use of behaviour in pain studies. Similarly, physiological indices of pain can also vary and may be confounded by influence from non-painful stimuli. In mammals, changes in the frequency spectrum of the electroencephalogram (EEG) recorded under light anaesthesia (the minimal anaesthesia model; MAM) have been shown to reliably indicate cerebral responses to noxious stimuli in a range of species...

PURPOSE: As the number of survivors continues to increase with improvements in breast cancer treatment, greater emphasis has been placed on the aesthetic outcome following breast surgery. Effort is made to minimize scarring on the breast, yet patients who require a port for treatment inevitably have a scar on the upper chest from the port itself. We hypothesized that patients with breast cancer are conscious of their port scars, and if given a choice would prefer placement of the port in the arm rather than the chest...

Heart failure is a common adverse effect associated with doxorubicin treatment. The aim of this study is to investigate the effect of ivabradine treatment on doxorubicin-induced heart failure in conscious rats. Rats were treated with doxorubicin (2.5 mg/kg/day) or ivabradine (10 mg/kg/day) alone or along with doxorubicin injections. Changes in heart rate variability (HRV), baroreflex sensitivity, left ventricular function, serum cardiac troponin T and cardiac histological features were taken as index parameters for the development of heart failure...

For years, phenomenological psychiatry has proposed that distortions of the temporal structure of consciousness contribute to the abnormal experiences described before schizophrenia emerges, and may relate to basic disturbances in consciousness of the self. However, considering that temporality refers mainly to an implicit aspect of our relationship with the world, disturbances in the temporal structure of consciousness remain difficult to access. Nonetheless, previous studies have shown a correlation between self disorders and the automatic ability to expect an event in time, suggesting timing is a key issue for the psychopathology of schizophrenia...

It has been proposed that awareness may depend on the highly-dynamic functional connectivity of large-scale cortico-thalamo-cortical networks. We investigated how brain connectivity changes over time in the resting state in a group of patients with chronic disorders of consciousness (DoC). To this end, we assessed dynamic functional connectivity (DFC) in the resting state by analyzing the time-dependent EEG phase synchronization in five frequency bands (δ, θ, α, β, and γ). Patients in Minimally Conscious State (MCS) showed changes in DFC matrices and topography over time (mainly in the γ range), which were significantly different from those observed in patients with Unresponsive Wakefulness Syndrome (UWS)...

Placebo effects have often been attributed to cognitive processes described as "learning" and/or "expectancy," yet the role of conscious awareness is unclear. Furthermore, little is known about the placebo effects in patients with limited cognitive abilities, such as intellectual disability. Here, recent data on placebo mechanisms in patients with impaired cognitive function will be discussed, as well as experimental studies investigating how implicit cognitive processes may shape placebo effects...

We applied the following methods to resting-state EEG data from patients with disorders of consciousness (DOC) for consciousness indexing and outcome prediction: microstates, entropy (i.e. approximate, permutation), power in alpha and delta frequency bands, and connectivity (i.e. weighted symbolic mutual information, symbolic transfer entropy, complex network analysis). Patients with unresponsive wakefulness syndrome (UWS) and patients in a minimally conscious state (MCS) were classified into these two categories by fitting and testing a generalised linear model...

OBJECTIVE: Investigate the relationship between consciousness and nociceptive responsiveness (i.e., Nociception Coma Scale-Revised [NCS-R]), examine the suitability of the NCS-R for assessing nociception in participants with disorders of consciousness (DoC) and replicate previous findings on psychometric properties of the scale. DESIGN: We prospectively assessed consciousness with the Coma Recovery Scale-Revised (CRS-R). Responses during baseline, non-noxious and noxious stimulations were scored with the NCS-R, CRS-R oromotor and motor subscales...
