Cognitive Motor Dissociation in Disorders of Consciousness.

BACKGROUND: Patients with brain injury who are unresponsive to commands may perform cognitive tasks that are detected on functional magnetic resonance imaging (fMRI) and electroencephalography (EEG). This phenomenon, known as cognitive motor dissociation, has not been systematically studied in a large cohort of persons with disorders of consciousness. METHODS: In this prospective cohort study conducted at six international centers, we collected clinical, behavioral, and task-based fMRI and EEG data from a convenience sample of 353 adults with disorders of consciousness. We assessed the response to commands on task-based fMRI or EEG in participants without an observable response to verbal commands (i.e., those with a behavioral diagnosis of coma, vegetative state, or minimally conscious state-minus) and in participants with an observable response to verbal commands. The presence or absence of an observable response to commands was assessed with the use of the Coma Recovery Scale-Revised (CRS-R). RESULTS: Data from fMRI only or EEG only were available for 65% of the participants, and data from both fMRI and EEG were available for 35%. The median age of the participants was 37.9 years, the median time between brain injury and assessment with the CRS-R was 7.9 months (25% of the participants were assessed with the CRS-R within 28 days after injury), and brain trauma was an etiologic factor in 50%. We detected cognitive motor dissociation in 60 of the 241 participants (25%) without an observable response to commands, of whom 11 had been assessed with the use of fMRI only, 13 with the use of EEG only, and 36 with the use of both techniques. Cognitive motor dissociation was associated with younger age, longer time since injury, and brain trauma as an etiologic factor. In contrast, responses on task-based fMRI or EEG occurred in 43 of 112 participants (38%) with an observable response to verbal commands. CONCLUSIONS: Approximately one in four participants without an observable response to commands performed a cognitive task on fMRI or EEG as compared with one in three participants with an observable response to commands.

Admission Viscoelastic Hemostatic Assay Parameters Predict Poor Long-Term Intracerebral Hemorrhage Outcomes.

BACKGROUND: Viscoelastic hemostatic assays (VHAs) provide more comprehensive assessments of coagulation compared with conventional coagulation assays. Although VHAs have enabled guided hemorrhage control therapies, improving clinical outcomes in life-threatening hemorrhage, the role of VHAs in intracerebral hemorrhage (ICH) is unclear. If VHAs can identify coagulation abnormalities relevant for ICH outcomes, this would support the need to investigate the role of VHAs in ICH treatment paradigms. Thus, we investigated whether VHA assessments of coagulation relate to long-term ICH outcomes. METHODS: Patients with spontaneous ICH enrolled into a single-center cohort study receiving admission Rotational Thromboelastometry (ROTEM) VHA testing between 2013 and 2020 were assessed. Patients with previous anticoagulant use or coagulopathy on conventional coagulation assays were excluded. Primary ROTEM exposure variables were coagulation kinetics and clot strength assessments. Poor long-term outcome was defined as modified Rankin Scale ≥ 4 at 6 months. Logistic regression analyses assessed associations of ROTEM parameters with clinical outcomes after adjusting for ICH severity and hemoglobin concentration. RESULTS: Of 44 patients analyzed, the mean age was 64 years, 57% were female, and the median ICH volume was 23 mL. Poor 6-month outcome was seen in 64% of patients. In our multivariable regression models, slower, prolonged coagulation kinetics (adjusted odds ratio for every second increase in clot formation time 1.04, 95% confidence interval 1.00-1.09, p = 0.04) and weaker clot strength (adjusted odds ratio for every millimeter increase of maximum clot firmness 0.84, 95% confidence interval 0.71-0.99, p = 0.03) were separately associated with poor long-term outcomes. CONCLUSIONS: Slower, prolonged coagulation kinetics and weaker clot strength on admission VHA ROTEM testing, not attributable to anticoagulant use, were associated with poor long-term outcomes after ICH. Further work is needed to clarify the generalizability and the underlying mechanisms of these VHA findings to assess whether VHA-guided treatments should be incorporated into ICH care.

Conducting a narrative medicine workshop in ambulatory palliative care: A feasibility and exploratory study.

OBJECTIVES: This pilot study aimed to assess the feasibility and impact of a narrative medicine group for patients receiving palliative care. METHODS: This pilot study aimed to assess the feasibility of a six-session, physician-led narrative medicine group for patients receiving palliative care. Ten patients were recruited by their outpatient providers. Symptom severity and patient dignity scores were collected pre-intervention, at the mid-point, and post-intervention using the Patient Dignity Inventory (PDI) and Edmonton Symptom Assessment Survey (ESAS). Qualitative reports of pain, expectations, and anticipated challenges were collected before the intervention. Participant interviews were conducted after the intervention to assess overall experience in the group, challenges experienced, recommendations for future endeavors, and general feedback. RESULTS: No significant changes in PDI or ESAS scores were observed at baseline, 3 weeks, and 6 weeks. Participants reported overall satisfaction, with 8 of 9 participants stating they "strongly agree" they would participate in the group again and recommend the group to others. Qualitative responses indicated benefits in the realms of relating to other patients, subjective reduction in pain, and relieving feelings of isolation. SIGNIFICANCE OF RESULTS: A narrative medicine group for ambulatory patients receiving palliative care appeared to be both beneficial and feasible when delivered through a virtual format. A randomized trial with a larger sample is needed to fully assess the impacts of engaging in narrative work on symptom burden, survival, and quality of life.

Injury patterns associated with cognitive motor dissociation.

In unconscious appearing patients with acute brain injury, wilful brain activation to motor commands without behavioural signs of command following, known as cognitive motor dissociation (CMD), is associated with functional recovery. CMD can be detected by applying machine learning to EEG recorded during motor command presentation in behaviourally unresponsive patients. Identifying patients with CMD carries clinical implications for patient interactions, communication with families, and guidance of therapeutic decisions but underlying mechanisms of CMD remain unknown. By analysing structural lesion patterns and network level dysfunction we tested the hypothesis that, in cases with preserved arousal and command comprehension, a failure to integrate comprehended motor commands with motor outputs underlies CMD. Manual segmentation of T2-fluid attenuated inversion recovery and diffusion weighted imaging sequences quantifying structural injury was performed in consecutive unresponsive patients with acute brain injury (n = 107) who underwent EEG-based CMD assessments and MRI. Lesion pattern analysis was applied to identify lesion patterns common among patients with (n = 21) and without CMD (n = 86). Thalamocortical and cortico-cortical network connectivity were assessed applying ABCD classification of power spectral density plots and weighted pairwise phase consistency (WPPC) to resting EEG, respectively. Two distinct structural lesion patterns were identified on MRI for CMD and three for non-CMD patients. In non-CMD patients, injury to brainstem arousal pathways including the midbrain were seen, while no CMD patients had midbrain lesions. A group of non-CMD patients was identified with injury to the left thalamus, implicating possible language comprehension difficulties. Shared lesion patterns of globus pallidus and putamen were seen for a group of CMD patients, which have been implicated as part of the anterior forebrain mesocircuit in patients with reversible disorders of consciousness. Thalamocortical network dysfunction was less common in CMD patients [ABCD-index 2.3 (interquartile range, IQR 2.1-3.0) versus 1.4 (IQR 1.0-2.0), P < 0.0001; presence of D 36% versus 3%, P = 0.0006], but WPPC was not different. Bilateral cortical lesions were seen in patients with and without CMD. Thalamocortical disruption did not differ for those with CMD, but long-range WPPC was decreased in 1-4 Hz [odds ratio (OR) 0.8; 95% confidence interval (CI) 0.7-0.9] and increased in 14-30 Hz frequency ranges (OR 1.2; 95% CI 1.0-1.5). These structural and functional data implicate a failure of motor command integration at the anterior forebrain mesocircuit level with preserved thalamocortical network function for CMD patients with subcortical lesions. Amongst patients with bilateral cortical lesions preserved cortico-cortical network function is associated with CMD detection. These data may allow screening for CMD based on widely available structural MRI and resting EEG.

Use of Champions Identified by Social Network Analysis to Reduce Health Care Worker Patient-Assist Injuries.

BACKGROUND: Safe patient handling and mobility (SPHM) programs recommend having champions, but have not indicated how to identify them and have confined their role to peer-based activities, limiting their ability to influence control measures. METHODS: In a pilot program conducted at a community access hospital in Oregon, researchers applied social network analysis (SNA) of safety advice to identify champion candidates. Candidates were invited to complete mobility, communication, and quality improvement (QI) training modules to become champions. Champions' roles included peer-based instruction and participation in QI quarterly meetings with hospital leaders. The program process was evaluated through weekly e-mail check-ins and documentation of quarterly meetings. Outcomes were evaluated with a pre-post design, observing 12-month changes in self-reported leading indicators and Good Catch reports, as well as trends in patient-assist injuries (2011-2019). RESULTS: SNA identified six candidates, four of whom became champions. Champions completed 48 weekly logs. The quarterly meetings concerned unitwide SPHM training, equipment storage, and onboarding. Results showed significant improvements in equipment use, safety participation, and safety compliance, particularly among workers who would seek SPHM advice from champions or recently hired workers. Compared with the prior year, the Good Catch monthly entries increased from 11.69 to 28.81. The average annual incidence rate of patient-assist injuries dropped from 13.01 for the six years before the program to 3.7 per 100 full-time equivalents (FTE) for the two years after. CONCLUSION: A program with SNA-identified and QI-trained champions improved safety outcomes after one year. Better-designed evaluations are needed to establish the replicability and long-term impact of this program.

An inquiry into how parents of children with autism spectrum disorder interact with their children in a motor skill-based play setting.

BACKGROUND: Most studies examining parental behaviors of parents of young children with autism spectrum disorder (ASD) and typically developing (TD) children have taken place in free play settings and have primarily focused on examining social behaviors. Motor skill-based play settings, which are distinctly different from free play settings, have not been explicitly studied as it relates to parental behaviors in these environments. AIMS: The purpose of this study was to examine parental behaviors of parents of children with and without ASD in two distinctly different play settings. METHODS: Parental behaviors of eighteen parents of children with (n = 9) and without ASD (n = 9) were examined by observation in different play settings (free play [a social-play/traditional play based setting] and a motor skill-based play setting). The examined parental behaviors included parental encouragement, negativity, sensitivity, detachment, and intrusiveness. A 2 × 2 (group × play setting) repeated measures of ANOVA was conducted to examine the main effect of group (TD vs ASD) and play setting (a social-play based setting and a motor skill-based setting) and the interaction effect between group and play setting on parental behaviors. Post-hoc independent t-tests between groups in each setting were conducted to follow-up on significant interactions indicated in the repeated measures of ANOVA RESULTS: The repeated measures ANOVA revealed that parental encouragement showed a significant interaction effect, suggesting that the effect of group on parental encouragement depended on play setting. A post-hoc analysis revealed that parents of children with ASD showed statistically significant lower parental encouragement in a motor skill-based play setting but not in a social-play based setting compared to parents of TD children. Moreover, there was a main effect of group (parents of children with ASD vs. parents of TD children) on parental intrusiveness indicating that the mean parental intrusiveness on children with ASD was significantly higher than parents of TD children across both play settings. There were no statistically significant main or interaction effects on the other parental behaviors (parental negativity, sensitivity, and detachment) between groups. CONCLUSIONS AND IMPLICATIONS: The current study indicated parental encouragement differences between parents of children with ASD and parents of TD children varied based on the play setting. These results identify a need to examine parental behaviors, especially parental encouragement and parental intrusiveness across various types of play settings. Furthermore, as parents of children with ASD displayed lower parental encouragement in a motor skill-based play setting compared to parents of TD children, future studies are warranted to improve parental encouragement of parents of children with ASD in a motor skill-based play setting.
