Background/objectives: The objective was to assess the relationships between neuropsychological impairments, functional outcome and life satisfaction in a longitudinal study of patients after a severe traumatic brain injury (TBI) (PariS-TBI study).

Patients: Out of 243 survivors, 86 were evaluated 8 years post-injury. They did not significantly differ from patients lost-to-follow up except for the latter being more frequently students or unemployed before the injury.

Background/objectives: Physical activity (PA) has significant benefits for older adults. However, the recommended PA is rarely achieved in nursing homes. In this proof of concept study, we assessed whether virtual reality (VR) could help to increase spontaneous PA during a stationary cycling session.

Article Synopsis
  • * Participants were assessed at multiple time points (1, 4, and 8 years post-injury), with over half demonstrating improvements in their Glasgow Outcome Scale Extended (GOSE) scores, mood, and cognitive functions between years 4 and 8.
  • * The findings revealed that more years of education were linked to better global functioning, and improvements in mood and reductions in anxiety and depression symptoms were also associated with these positive changes.

Background: There is variability among centres regarding the utilization of assisted peritoneal dialysis (PD). Functional impairment is one of the leading causes of assisted PD. Tools to assess the patient's ability to manipulate PD devices are required.

In this study, we report a complete (clinical, radiological, and virological) sustained (1 year) response after nivolumab salvage therapy in a progressive multifocal leukoencephalopathy patient. Analyses of the cells infiltrate in a pretreatment brain biopsy suggest that parenchymal programmed cell death-L1 macrophages could be the T-cells partnership in immune exhaustion and virus escape.

People with traumatic brain injury are frequently involved in a litigation because another person was at fault for causing the accident. A compensation amount will often be settled to compensate the victim for the past, present, future damages and losses suffered. We report descriptive data about the full and final personal compensation amount and investigated its association with patient's outcomes.

Severe traumatic brain injury is a leading cause of acquired persistent disabilities, and represents an important health and economic burden. However, the determinants of long-term outcome have rarely been systematically studied in a prospective longitudinal study of a homogeneous group of patients suffering exclusively from severe TBI Prospective observational study of an inception cohort of adult patients with severe traumatic brain injury in the Parisian area (PariS-TBI). Outcome was assessed with face-to-face interview 8 years after Traumatic Brain Injury, focusing on impairments, activity limitations, and participation restriction.

Exertional leg pain is a common and disabling condition in athletes with challenging diagnosis and management. We report the case of a 29-year-old rugby player with a history and clinical examination consistent with chronic exertional compartment syndrome (CECS). Compartment pressure measurement was supportive of the diagnosis.

Article Synopsis
  • The study aimed to create and validate a questionnaire, called the Barriers to Physical Activity After Stroke (BAPAS), to identify obstacles faced by stroke survivors in maintaining physical activity.
  • In two stages, the research combined interviews with stroke survivors and input from experts to identify and categorize these barriers.
  • The resulting BAPAS, validated through statistical methods, showed strong reliability and correlation with disability severity, indicating it can effectively assess barriers to physical activity in this population.

After a traumatic brain injury (TBI), behavioral disorders can occur without major focal brain lesion, and in these situations, their pathophysiology remains unclear. The aim of this study is to examine whether TBI patients with behavioral disorders but without any focal damage, as observed from an initial clinical CT scan, present subtle volumetric alterations that could be measured voxel-by-voxel in the whole brain with MRI. Eight male adults with severe TBI who had behavioral sequela but not major focal cerebral lesion and 17 age-matched controls underwent a volumetric T1-weighted 1.

Objective: To evaluate the patient's awareness of his or her difficulties in the chronic phase of severe traumatic brain injury (TBI) and to determine the factors related to poor awareness.

Design/setting/subjects: This study was part of a larger prospective inception cohort study of patients with severe TBI in the Parisian region (PariS-TBI study). Intervention/Main measures: Evaluation was carried out at four years and included the Brain Injury Complaint Questionnaire (BICoQ) completed by the patient and his or her relative as well as the evaluation of impairments, disability and quality of life.

Objective: To describe employment outcome four years after a severe traumatic brain injury by the assessment of individual patients' preinjury sociodemographic data, injury-related and postinjury factors.

Design: A prospective, multicenter inception cohort of 133 adult patients in the Paris area (France) who had received a severe traumatic brain injury were followed up postinjury at one and four years. Sociodemographic data, factors related to injury severity and one-year functional and cognitive outcomes were prospectively collected.

Purpose: To analyze the effect of litigation procedures on long-term outcomes in severe traumatic brain injury.

Materials And Methods: Prospective observational follow-up of an inception cohort including 504 adults with severe traumatic brain injury recruited in 2005-2007 in the Parisian area, France, with initial, one- and four-year outcomes measures.

Results: Four years after the traumatic brain injury, 147 patients, out of 257 who survived the acute phase, were assessed.

Objectives: To assess predictors and indicators of disability and quality-of-life 4 years after severe traumatic brain injury (TBI), using structural equation modelling (SEM).

Methods: The PariS-TBI study is a longitudinal multi-centre inception cohort study of 504 patients with severe TBI. Among 245 survivors, 147 patients were evaluated upon 4-year follow-up, and 85 completed the full assessment.

Objective: To assess brain injury services utilization and their determinants using Andersen's model.

Methods: Prospective follow-up of the PariS-TBI inception cohort. Out of 504 adults with severe traumatic brain injury (TBI), 245 survived and 147 received a 4-year outcome assessment (mean age 33 years, 80% men).

Article Synopsis
  • This study aimed to evaluate electromyographic changes in patients experiencing different symptoms (asymptomatic, fatigue, pseudobotulism) after receiving botulinum toxin injections.
  • It involved analyzing single-fiber electromyography (SFEMG) in specific muscles of four groups of patients with varying degrees of symptoms, finding significant abnormalities in the pseudobotulism group compared to controls.
  • The results indicated that while patients with pseudobotulism displayed notable muscle issues, those with fatigue showed no major electromyographic signs of toxin diffusion, suggesting their fatigue might stem from other causes.

The Dysexecutive Questionnaire (DEX; Wilson, Pettigrew, & Teasdale, 1998 ) has been designed to assess executive dysfunctions in daily life. However, its relationships with cognitive testing, mood, and the ability to fulfil daily life demands, have not yet been systematically addressed. The objective of this study was to address these issues in a prospective four-year follow-up study of patients with severe traumatic brain injury (TBI) (PariS-TBI study).
