Aims: to assess occurrence and clinical correlates of neurogenic heterotopic ossifications (NHO) in patients with prolonged disorder of consciousness (DoC). Design: multi-center cross-sectional observational study. Setting: 23 intensive neurorehabilitation units. Subjects: 287 patients with prolonged disorder of consciousness (DoC; 150 in vegetative state, VS, and 128 in minimally conscious state, MCS) of different etiology (vascular = 125, traumatic = 83, anoxic = 56, others = 14). Main Measures: clinical evidence of NHO confirmed by standard radiological and/or sonographic evaluation; Coma Recovery Scale-Revised; Disability Rating Scale (DRS); Early Rehabilitation Barthel Index; presence of ventilator support, spasticity, bone fractures and paroxysmal sympathetic hyperactivity. Results: 31 patients (11.2%) presented NHO. Univariate analyses showed that NHO was associated with VS diagnosis, traumatic etiology, high DRS category and total score, and high occurrence of limb spasticity and bone fractures. A cluster-corrected binary logistic regression model (excluding spasticity available in a subset of patients) showed that only lower DRS total score and presence of bone fractures were independently associated with NHO. Conclusions: NHO are relatively frequent in patients with DoC, and are independently associated with functional disability, bone fractures and spasticity. These findings contribute to identifying patients with DoC prone to develop NHO and requiring special interventions to improve functional recovery. [ABSTRACT FROM AUTHOR]

Aim: to assess overall clinical complexity of patients with acquired disorders of consciousness (DoC) in vegetative state/unresponsive wakefulness syndrome (VS/UWS) vs. minimally conscious state- MCS) and in different etiologies.. Design: Multi-center cross-sectional observational study. Setting: 23 intensive neurorehabilitation units. Subjects: 264 patients with DoC in the post-acute phase: VS/UWS = 141, and MCS = 123 due to vascular (n = 125), traumatic (n = 83) or anoxic (n = 56) brain injury. Main Measures: Coma Recovery Scale-Revised, and Disability Rating Scale (DRS); presence of medical devices (e.g., for eating or breathing); occurrence and severity of medical complications. Results: patients in DoC, and particularly those in VS/UWS, showed severe overall clinical complexity. Anoxic patients had higher overall clinical complexity, lower level of responsiveness/consciousness, higher functional disability, and higher needs of medical devices. Vascular patients had worse premorbid clinical comorbidities. The two etiologies showed a comparable rate of MC, higher than that observed in traumatic etiology. Conclusion: overall clinical complexity is significantly higher in VS/UWS than in MCS, and in non-traumatic vs. traumatic etiology. These findings could explain the worse clinical evolution reported in anoxic and vascular etiologies and in VS/UWS patients and contribute to plan patient-tailored care and rehabilitation programmes.

Objectives: To analyse the possible presence of reduced cognitive efficiency in family caregivers of patients with prolonged disorders of consciousness (DOC). Subjects: The participants were 27 caregivers of 25 patients with DOC admitted to the severe brain injury units of the ICS Maugeri, Institutes of Telese Terme and Sciacca, Italy. Methods: We examined cognitive functions such as short- and long-term memory, executive functions and attention by means of standardized tests. We also assessed features of psychological distress such as anxiety, depression, psychophysiological symptoms, prolonged grief disorder, psychological burden and quality of life. All scores on neuropsychological tests were compared with those of the 15 matched control subjects. Results: Enrolled family caregivers showed high frequency of clinically relevant depressive symptoms and anxiety; half of them met the criteria for prolonged grief disorder. Caregivers achieved scores lower than the matched controls on tests for selective attention, verbal fluency and long-term spatial memory. Conclusions: Family caregivers’ burden is associated with a reduced efficiency of selected executive measures and visuospatial learning. These results emphasize the need for appropriate psychological and cognitive supporting therapies for family caregivers of patients with DOC, also considering their delicate involvement in clinical decision-making and in providing care.
