Good Health-Related Quality of Life in Older Patients One Year after mTBI despite Incomplete Recovery: An Indication of the Disability Paradox?

Background: Older adults (OAs) with mild traumatic brain injury (OA-mTBI) are a growing population, but studies on long-term outcomes and quality of life are scarce. Our aim was to determine the health-related quality of life (HRQoL) in OA-mTBI one year after injury and to assess the early predictors of HRQoL. Methods: Data from a prospective follow-up study of 164 older (≥60 years) and 289 younger mTBI patients (<60 years) admitted to the emergency department were analyzed. Post-traumatic complaints, emotional distress and coping were evaluated 2 weeks post-injury using standardized questionnaires. At 12 months post-injury, HRQoL and functional recovery were determined with the abbreviated version of the World Health Organization Quality of Life scale and Glasgow Outcome Scale Extended (GOSE), respectively. Results: One year post-injury, 80% (n = 131) of the OA-mTBI rated their HRQoL as "good" or "very good", which was comparable to younger patients (79% (n = 226), p = 0.72). Incomplete recovery (GOSE <8) was present in 43% (n = 69) of OA-mTBI, with 67% (n = 46) reporting good HRQoL. Two weeks post-injury, fewer OA-mTBI had (≥2) post-traumatic complaints compared to younger patients (68% vs. 80%, p = 0.01). In the multivariable analyses, only depression-related symptoms (OR = 1.20 for each symptom, 95% CI = 1.01-1.34, p < 0.01) were predictors of poor HRQoL in OA-mTBI. Conclusions: Similar to younger patients, most OA-mTBI rated their HRQoL as good at one year after injury, although a considerable proportion showed incomplete recovery according to the GOSE, suggesting a disability paradox. Depression-related symptoms emerged as a significant predictor for poor HRQoL and can be identified as an early target for treatment after mTBI.

Identification of At-Risk Patients That Need More Intensive Treatment Following mTBI: Post-Hoc Insights From the UPFRONT-Study.

To investigate which factors within an at-risk group make patients less likely to benefit from preventive treatment following mild traumatic brain injury (mTBI). Inclusion in 3 level I trauma centers in the Netherlands. Data collection through surveys as outpatients. mTBI patients (18-66 years), reporting 3 or more complaints 2 weeks postinjury (at-risk status). Eighty-four patients included and randomized (39 patients cognitive behavioral therapy, 45 patients telephonic counseling). Eighty patients filled out the questionnaires 12 months postinjury. Post hoc analysis investigating 80 patients as 1 at-risk group receiving psychological treatment. Post hoc study of a randomized controlled trial (RCT). Binomial logistic regression performed determining which variables 2 weeks postinjury contributed strongly to unsuccessful return to work/study (RTW) and unfavorable outcome at 12 months. RTW and functional outcome as measured with the Glasgow Outcome Scale-Extended (GOSE) at 12 months postinjury. Out of 80 patients, 43 (53.8%) showed a favorable functional outcome at 12 months, and 56 (70%) patients had a full RTW. Patients with unfavorable outcome had a higher age and higher reports of anxiety, depression at 2 weeks and 12 months postinjury. Patients with an unsuccessful RTW had a higher age and higher reports of depression, and posttraumatic stress disorder at 2 weeks and 12 months postinjury. A logistic regression model for functional outcome (GOSE) was statistically significant (χ² 7 = 40.30, P < .0001). Of 6 predictor variables, 3 were significant: anxiety, depression, and treatment condition. For RTW, logistic regression was also statistically significant (χ² 7 = 19.15, P = .008), with only 1 out of 6 predictor variables (ie, age) being significant. Main findings comprise differences in demographic and psychological measures between patients with favorable and unfavorable outcomes and patients with RTW versus no RTW. Prediction models of outcome and RTW showed several psychological measures at 2 weeks greatly determining patients' likelihood benefitting from the preventive treatment. Results suggest that from the beginning there are some patients for whom a short preventive treatment is not sufficient. Selection and treatment of at-risk patients might be better based on psychological symptoms instead of posttraumatic complaints.

Awake craniotomy does not lead to increased psychological complaints.

Patients with brain tumours are increasingly treated by using the awake craniotomy technique. Some patients may experience anxiety when subjected to brain surgery while being fully conscious. However, there has been only limited research into the extent to which such surgeries actually result in anxiety or other psychological complaints. Previous research suggests that undergoing awake craniotomy surgery does not lead to psychological complaints, and that post-traumatic stress disorders (PTSD) are uncommon following this type of surgery. It must be noted, however, that many of these studies used small random samples. In the current study, 62 adult patients completed questionnaires to identify the degree to which they experienced anxiety, depressive and post-traumatic stress complaints following awake craniotomy using an awake-awake-awake procedure. All patients were cognitively monitored and received coaching by a clinical neuropsychologist during the surgery. In our sample, 21% of the patients reported pre-operative anxiety. Four weeks after surgery, 19% of the patients reported such complaints, and 24% of the patients reported anxiety complaints after 3months. Depressive complaints were present in 17% (pre-operative), 15% (4weeks post-operative) and 24% (3months post-operative) of the patients. Although there were some intra-individual changes (improvement or deterioration) in the psychological complaints over time, on group-level postoperative levels of psychological complaints were not increased relative to the preoperative level of complaints. The severity of post-operative PTSD-related complaints were rarely suggestive of a PTSD. Moreover, these complaints were seldom attributed to the surgery itself, but appeared to be more related to the discovery of the tumour and the postoperative neuropathological diagnosis. The results of the present study do not indicate that undergoing awake craniotomy is associated with increased psychological complaints. Nevertheless, psychological complaints may well exist as a result of other factors. Consequently, monitoring the patient's mental wellbeing and offering psychological support where necessary remain important.

Diagnostic values of history taking, physical examination and KT-1000 arthrometer for suspect anterior cruciate ligament injuries in children and adolescents: a prospective diagnostic study

BackgroundDiagnosing anterior cruciate ligament (ACL) injuries in children and adolescents are more challenging compared to adults. Delayed diagnosis may result in meniscal or chondral injuries. The aim of this study was to determine the diagnostic values of history taking, physical examination and KT-1000 arthrometer for suspect ACL injuries in children and adolescents.MethodsIn this prospective diagnostic study, all children and adolescents (< 18 years) with post-traumatic knee complaints presenting at the out-patient department of the Máxima MC were eligible for inclusion. One experienced knee specialised orthopaedic surgeon was blinded and performed history taking, physical examination and KT-1000 arthrometer measurement. All patients had a magnetic resonance imaging (MRI) for the final diagnosis. Diagnostic values of interest were sensitivity, specificity, positive and negative predictive values (PPV and NPV). The outcomes of the KT-1000 arthrometer were drafted in a relative operating characteristics (ROC) curve to determine the optimal cut-off points.ResultsSixty-six patients were included, of which 50 had an ACL rupture and 16 had no ACL rupture on MRI. Report of a popping sensation during trauma had a specificity and PPV of 100% for diagnosing ACL injuries. The PPV and NPV of the Lachman test (in case of describing end-feel) were 95 and 82%, of the anterior drawer test 87 and 90% and of the pivot shift test 95 and 81% respectively. The optimal cut-off point of the KT-1000 arthrometer at 133 N force was an absolute translation of ≥7 mm with a PPV and NPV of 97 and 88% respectively.ConclusionsReport of a popping sensation during trauma has a specificity and PPV of 100% for diagnosing ACL injuries in children and adolescents. Although potentially difficult in children, the Lachman test, anterior drawer test and pivot shift test have a high PPV and NPV when performed by an experienced orthopaedic surgeon. An absolute anterior translation of ≥7 mm of the injured knee in the KT-1000 arthrometer at 133 N has the highest diagnostic values of all tests for diagnosing ACL injuries.Level of evidence3

0642 Characterizing Actigraphy-Measured Sleep Disturbance in Veterans and Service Members with Post-traumatic Headache following Mild Traumatic Brain Injury

Abstract Introduction Post-traumatic headache (PTH) frequently occur following traumatic brain injury (TBI) is particularly prevalent in Veterans with deployment-related TBI. PTH is associated with a range of physical and mental health symptoms, including post-traumatic stress disorder (PTSD), depression, anxiety, post-concussive symptoms, and subjective sleep complaints. Subjective sleep disturbance is associated with greater pain severity, and headaches (HA) are associated with poorer sleep. Poor sleep may be a mechanism by which PTH exerts both direct and indirect effects on health outcomes Despite the high prevalence of sleep problems in individuals with PTH, we know little about sleep disturbance in Veterans and military personnel with PTH. This study sought to characterize the relationship between objective sleep disturbance and HA in Veterans and military personnel with chronic PTH following mild TBI. Methods Veterans and active-duty service members (N=39, Mage= 49.4, 89.7% male) were included from a larger study evaluating prazosin as prophylactic treatment for persistent PTH. Participants completed baseline measures of PTSD symptoms, insomnia, sleep quality, HA frequency and impairment, as well as 7-day actigraphy, sleep diary, and HA logs. Actigraphy-derived sleep parameters include sleep onset latency (SOL), total sleep time (TST), sleep efficiency (SE), and wake after sleep onset (WASO). Daily HA logs were used to assess HA severity and duration. Analyses were conducted in SPSS 26.0 using multilevel modeling, controlling for the effects of time. Results Preliminary results suggest number of HA days at baseline was significantly associated with self-reported sleep quality (r=-.398, p= .016), but not with subjective SOL, TST, or WASO. Number of HA days was significantly correlated with actigraphy-measured WASO (r=.178, p=.003). Actigraphy-measured SOL, SE, WASO, and TST were not significantly associated with same-day HA severity and duration. Conclusion This preliminary data suggest examination of sleep fragmentation may be important in enhancing our understanding of PTH and related impairment. Findings support the importance of using both subjective and objective measures in the assessment of sleep in Veterans and service members with PTH.

Effects of Mild Traumatic Brain Injury on Resting State Brain Network Connectivity in Older Adults

Older age is associated with worsened outcome after mild traumatic brain injury (mTBI) and a higher risk of developing persistent post-traumatic complaints. However, the effects of mTBI sequelae on brain connectivity at older age and their association with post-traumatic complaints remain understudied.We analyzed multi-echo resting-state functional magnetic resonance imaging data from 25 older adults with mTBI (mean age: 68 years, SD: 5 years) in the subacute phase (mean injury to scan interval: 38 days, SD: 9 days) and 20 age-matched controls. Severity of complaints (e.g. fatigue, dizziness) was assessed using self-reported questionnaires. Group independent component analysis was used to identify intrinsic connectivity networks (ICNs). The effects of group and severity of complaints on ICNs were assessed using spatial maps intensity (SMI) as a measure of within-network connectivity, and (static) functional network connectivity (FNC) as a measure of between-network connectivity.Patients indicated a higher total severity of complaints than controls. Regarding SMI measures, we observed hyperconnectivity in left-mid temporal gyrus (cognitive-language network) and hypoconnectivity in the right-fusiform gyrus (visual-cerebellar network) that were associated with group. Additionally, we found interaction effects for SMI between severity of complaints and group in the visual(-cerebellar) domain. Regarding FNC measures, no significant effects were found.In older adults, changes in cognitive-language and visual(-cerebellar) networks are related to mTBI. Additionally, group-dependent associations between connectivity within visual(-cerebellar) networks and severity of complaints might indicate post-injury (mal)adaptive mechanisms, which could partly explain post-traumatic complaints (such as dizziness and balance disorders) that are common in older adults during the subacute phase.

Role of Magnetic Resonance Imaging in Evaluation of Post Traumatic Ankle Joint

Background: The ankle joint injuries are common emergency and account for about 10% of all visits to emergency departments. This is usually due to a sprain related to sports, walking, fall, or road traffic accident. Ankle joint has a complex three-dimensional anatomy, so MRI is considered the modality of the choice in evaluating patients with ankle problems. MRI provides precise information about soft tissue, skeletal and extra-skeletal lesions. Objectives: To evaluate the role of magnetic resonance imaging (MRI) in the detection of abnormalities and injuries associated with post traumatic ankle joint. Patients and methods: A descriptive cross-sectional study was conducted from July 2019 to April 2021. Sixty patients with post-traumatic ankle joint complaints underwent MRI examination during this period. All patients performed MRI examination in the Radiology Department, Menoufia University Hospital after signing informed consent. Results: Out of 60 patients, nine (16%) were diagnosed with ligamentous injuries, 29 (48.3%) were diagnosed with tendon injuries and 35 (58.3%) were diagnosed with bone injuries. Nine (15%) were fractures, one (1.7%) was bone necrosis and 34 (56.7%) were bone contusions. 55 (91.7%) had joint effusion and 11 (18.3%) had sinus tarsi syndrome. Conclusion: MRI is the modality of choice in evaluating ankle injuries because of its high soft tissue contrast resolution and multi-planar capabilities. It is an ideal modality for global evaluation of the osseous and soft tissue structures of the ankle.

Visuomotor reaction time difference between patellofemoral pain syndrome and healthy individuals: Cross-sectional study

ObjectiveAlthough many studies indicated a decreased reaction time in post-traumatic complaints including ACL injury, no study has been devoted to measure reaction time in patients with patellofemoral pain syndrome (PFPS). The purpose of the present study was to compare the visuomotor reaction time between PFPS and healthy individuals. MethodsTwenty five patients with PFPS (20 women and 5 men, mean age 29.28 years, SD 5.59) and 25 healthy controls (19 women, 6 men, mean age 29.32, years SD 5.30) were recruited in the present study. The dependent variables were upper extremity reaction time, upper extremity error rate, knee extension reaction time in both involved and non-involved legs, plantar flexion reaction time in both involved and non-involved legs. ResultsThe results of one-way multiple analysis of variance showed that patients with PFPS had slower upper extremity reaction time (P=0.047, Effect size (ES)=0.39) and plantar flexion reaction time (symptomatic side) (P<0.001, ES=0.77) as compared with healthy control. The symptomatic knee extension reaction time was slower than the healthy matched leg, but this difference was not statistically significant (P=0.296, ES= 0.19). ConclusionThe present study suggests that the reaction time might be considered as a factor associated with PFPS.

Patients with mild traumatic brain injury and acute neck pain at the emergency department are a distinct category within the mTBI spectrum: a prospective multicentre cohort study

BackgroundAcute neck pain (ANP) has recently been demonstrated to be a predictor of persistent posttraumatic complaints after mild traumatic brain injury (mTBI). The aim of this study was to determine specific characteristics of patients with ANP following mTBI, their posttraumatic complaints and relationship with functional outcome.MethodsData from a prospective follow-up study of 922 mTBI patients admitted to the emergency department (ED) in three level-one trauma centres were analysed. Patients were divided into two groups: 156 ANP patients and 766 no acute neck pain (nANP) patients. Posttraumatic complaints were evaluated 2 weeks and 6 months post-injury using standardized questionnaires and functional outcome was evaluated at 6 months with the Glasgow Outcome Scale Extended (GOSE).ResultsANP patients were more often female (p < 0.01), younger (38 vs. 47 years, p < 0.01) with more associated acute symptoms at the ED (p < 0.05) compared to nANP patients. More motor vehicle accidents (12% vs. 6%, p = 0.01) and less head wounds (58% vs. 73%, p < 0.01) in ANP patients indicated ‘high-energy low-impact’ trauma mechanisms. ANP patients showed more posttraumatic complaints 2 weeks and 6 months post-injury (p < 0.05) and more often incomplete recovery (GOSE < 8) was present after 6 months (56% vs. 40%, p = 0.01).ConclusionsMTBI patients with acute neck pain at the ED constitute a distinct group within the mTBI spectrum with specific injury and demographic characteristics. Early identification of this at risk group already at the ED might allow specific and timely treatment to avoid development of incomplete recovery.

The Utility of the Mayo-Portland Adaptability Inventory Participation Index (M2PI) in US Military Veterans With a History of Mild Traumatic Brain Injury.

To examine the utility of the Mayo-Portland Adaptability Inventory-4th Edition Participation Index (M2PI) as a self-report measure of functional outcome following mild traumatic brain injury (mTBI) in US Military veterans. Department of Veterans Affairs Polytrauma Rehabilitation Center specialty hospital. On hundred thirty-nine veterans with a history of self-reported mTBI. Retrospective cross-sectional examination of data collected from regular clinical visits. M2PI, Neurobehavioral Symptoms Inventory with embedded validity measures, Posttraumatic Stress Disorder Checklist-Military Version. Forty-one percent of the sample provided symptom reports that exceeded established cut scores on embedded symptom validity tests. Invalid responders had higher levels of unemployment and endorsed significantly greater functional impairment, posttraumatic stress symptoms, and postconcussive complaints. For valid responders, regression analyses revealed that self-reported functioning was primarily related to posttraumatic stress complaints, followed by postconcussive cognitive complaints. For invalid responders, posttraumatic stress complaints also predicted self-reported functioning. Caution is recommended when utilizing the M2PI to measure functional outcome following mTBI in military veterans, particularly in the absence of symptom validity tests.

Structural Validity of the World Assumption Scale.

The World Assumption Scale (WAS) is a frequently used measure in trauma research. The 32 items of the WAS are intended to represent eight assumptions about the benevolence of the world, the meaningfulness of events, and the worthiness of the self. Debate about the validity of the WAS is ongoing, particularly in terms of its empirical factor structure; some studies have confirmed a model of eight correlated factors whereas several other studies have not. The WAS items were administered to a clinical sample of patients who sought professional help because of posttraumatic complaints (n = 1,791) as well as a sample of healthcare professionals (n = 236). We split the clinical sample into three subsamples, then performed exploratory factor analysis using data from one subsample and tested the factor structure with confirmatory factor analysis using the other two subsamples. A consistent model of eight correlated factors was demonstrated, with almost all factors showing acceptable reliability, Cronbach's αs = .68–.84. We tested this factor model against data from the sample of healthcare professionals with increasingly stringent levels of invariance and found it to be scalar invariant (same structure, loadings, and thresholds). In a regression analysis, five factors showed significant associations with posttraumatic stress disorder (PTSD) symptoms, and two factors had unique associations with PTSD symptoms after we controlled for traumatic events: Self‐Worth, β = −.31; and Luck, β = −.15. Future research should aim to distinguish between different assumptions and their individual influences on posttraumatic complaints.

Early Predictors for Long-Term Functional Outcome After Mild Traumatic Brain Injury in Frail Elderly Patients.

To identify the effect of frailty and early postinjury measures on the long-term outcome after mild traumatic brain injury in elderly patients. Patients admitted to 3 Dutch hospitals designated as level 1 trauma centers. The elderly (≥60 years) with mild traumatic brain injury (N = 161). A prospective observational cohort study. Posttraumatic complaints and the Hospital Anxiety and Depression Scale determined 2 weeks postinjury; the Glasgow Outcome Scale Extended and Groningen frailty indicator determined 1 to 3 years postinjury. A total of 102 nonfrail (63%) and 59 frail elderly (37%) patients, mean age of 70.8 (6.3) years were included. Most patients (54%; 72% nonfrail and 24% frail) recovered completely 1 to 3 years postinjury. Two weeks postinjury, 81% had posttraumatic complaints (83% frail and 80% nonfrail elderly), and 30% showed emotional distress (50% frail and 20% nonfrail). Frailty (odds ratio, 2.1; 95% confidence interval, 1.59-2.77) and presence of early complaints (odds ratio, 1.13; 95% confidence interval, 1.01-1.27) (Nagelkerke R = 46%) were found to predict long-term outcome, whereas age was not a significant predictor. The frail elderly had worse long-term outcome, and early complaints were found to be a stronger predictor of unfavorable outcome than age. Understanding the implications of frailty on outcome could help clinicians recognize patients at risk of a poor outcome and allocate care more efficiently.

Eye movement desensitization and reprocessing (EMDR) in children and adolescents with subthreshold PTSD after medically related trauma: design of a randomized controlled trial

ABSTRACTBackground: Three in every 10 children and adolescents admitted to a hospital or undergoing medical treatment develop subthreshold symptoms of posttraumatic stress disorder (PTSD). When untreated, subthreshold PTSD can have a serious impact on psychosocial functioning, quality of life and long-term psychopathology. However, research investigating subthreshold PTSD and its treatment following paediatric medical interventions and/or hospitalization is scarce. Eye Movement Desensitization and Reprocessing (EMDR) is a fast and non-invasive psychosocial treatment for posttraumatic stress complaints. However, the effectiveness of EMDR in paediatric patients with subthreshold PTSD has not previously been systematically investigated.Objective: Describing the design of a randomized controlled trial (RCT) set up to evaluate the effectiveness of EMDR in children with subthreshold PTSD after hospitalization.Method: Children aged 4–15 years who have undergone a one-time (trauma type I) or repeated (trauma type II) hospitalization up to five years ago will be included. Participating children will be first screened with a standardized questionnaire for PTSD-symptoms. Subsequently, children with subthreshold PTSD will be randomly assigned to (1) approximately six sessions of standardized EMDR or (2) care as usual (CAU). Children with full diagnostic PTSD do not participate in the RCT, but are referred for direct treatment. Follow-up measurements will take place after eight weeks and eight months.Discussion: Considering the scarce evidence for the effectiveness of EMDR in children with medically related trauma, clinicans, researchers and children treated in hospitals can benefit from this study. Potential strengths and limitations of this study are discussed.Trial Registration: Netherlands Trial Register NTR5801

The Default Mode Network as a Biomarker of Persistent Complaints after Mild Traumatic Brain Injury: A Longitudinal Functional Magnetic Resonance Imaging Study.

The objective of this study was to examine longitudinal functional connectivity of resting-state networks in patients with and without complaints after uncomplicated mild traumatic brain injury (mTBI). Second, we aimed to determine the value of network connectivity in predicting persistent complaints, anxiety, depression and long-term outcome. Thirty mTBI patients with three or more post-traumatic complaints at 2 weeks post-injury, 19 without complaints, and 20 matched healthy controls were selected for this study. Resting-state functional MRI (fMRI) was performed in patients at 1 month and 3 months post-injury, and once in healthy controls. Independent component analysis (ICA) was used to investigate the default mode, executive and salience networks. Persistent post-traumatic complaints, anxiety, and depression were measured at 3 months post-injury, and outcome was determined at 1 year post-injury. Within the group with complaints, higher functional connectivity between the anterior and posterior components of the default mode network at 1 month post-injury was associated with a greater number of complaints at 3 months post-injury (ρ = 0.59, p = 0.001). Minor longitudinal changes in functional connectivity were found for patients with and without complaints after mTBI, which were limited to connectivity within the precuneus component of the default mode network. No significant results were found for the executive and salience networks. Current results suggest that the default mode network may serve as a biomarker of persistent complaints in patients with uncomplicated mTBI.

Prediction of work resumption and sustainability up to 1 year after mild traumatic brain injury.

To study return to work (RTW) after mild traumatic brain injury (mTBI) at several intervals after injury and to predict RTW on the basis of occupational factors in addition to demographic, personality, and injury-related factors at 6 and 12 months after injury. This was a prospective cohort study (UPFRONT study, n = 1,151) of patients with mTBI admitted to the emergency department. Patients received questionnaires at 2 weeks and 3, 6, and 12 months after injury. RTW was divided into 3 levels: complete (cRTW), partial (pRTW), and no RTW. Rates of cRTW increased from 34% at 2 weeks to 77% at 12 months after injury, pRTW varied from 8% to 16% throughout the year. Logistic regression (complete vs incomplete RTW) demonstrated that apart from previously identified predictors such as demographics (e.g., age and education) and injury characteristics (e.g., cause and severity of injury) and indicators of psychological distress, occupational factors were of influence on work resumption after 6 months (area under the curve [AUC] = 0.82), At 12 months, however, the model was based solely on the presence of extracranial injuries and indicators of maladaptation after injury (AUC = 0.81). RTW after mTBI is a gradual process, with varying levels of RTW throughout the first year after injury. Different predictors were relevant for short- vs long-term work resumption, with occupational factors influencing short-term RTW. However, for both short- and long-term RTW, posttraumatic complaints and signs of psychological distress early after injury were relevant predictors, allowing early identification of patients at risk for problematic work resumption.

Cognitive Behavioral Intervention Compared to Telephone Counseling Early after Mild Traumatic Brain Injury: A Randomized Trial.

Many patients do not return to work (RTW) after mild traumatic brain injury (mTBI) because of persistent complaints that are often resistant to therapy in the chronic phase. Recent studies suggest that psychological interventions should be implemented early post-injury to prevent patients from developing chronic complaints. This study is a randomized, controlled trial that examines the effectiveness of a newly developed cognitive behavioral therapy (CBT) intervention (CBTi) compared to telephonic counseling (TC) in at-risk mTBI patients (patients with high reports of early complaints). Patients underwent either five sessions of CBT treatment or five phone conversations starting 4-6 weeks post-trauma. The main outcome measure was RTW 6 and 12 months post-trauma. Secondary measures comprised functional outcome at 6 and 12 months, and depression, anxiety, and reported post-traumatic complaints at 3, 6, and 12 months post-injury. After excluding dropouts, CBTi consisted of 39 patients and TC of 45 patients. No significant differences were found with regard to RTW, with 65% of CBTi patients and 67% of TC patients reporting a RTW at previous level. However, TC patients reported fewer complaints at 3 (8 vs. 6; p = 0.010) and 12 months post-injury (9 vs. 5; p = 0.006), and more patients in the TC group showed a full recovery 12 months post-injury compared to the CBTi group (62% vs. 39%). The results of this study suggest that early follow-up of at-risk patients can have a positive influence on patients' well-being, and that a low-intensive, low-cost telephonic intervention might be more effective than a CBT intervention at improving outcome in at-risk patients.

The association between microhaemorrhages and post - traumatic functional outcome in the chronic phase after mild traumatic brain injury.

In the chronic phase after mild traumatic brain injury (mTBI), microhaemorrhages are frequently detected on magnetic resonance imaging (MRI). It is however unclear whether microhaemorrhages are associated with functional outcome and which MRI sequence is most appropriate to address this association. We aimed to determine the association between microhaemorrhages and functional outcome in the chronic posttraumatic phase after injury with the most suitable MRI sequence to address this association. One hundred twenty-seven patients classified with mTBI admitted to the outpatient clinic from 2008 to 2015 for persisting posttraumatic complaints were stratified according to the presence of MRI abnormalities (n=63 (MRI+ group) and n=64 without abnormalities (MRI- group)). For the detection of microhaemorrhages, susceptibility-weighted imaging (SWI) and T2* gradient recalled echo (T2*GRE) were used. The relation between the functional outcome (dichotomized Glasgow Outcome Scale Extended scores) and the number and localization of microhaemorrhages was analysed using binary logistic regression. SWI detected twice as many microhaemorrhages compared to T2*GRE: 341 vs. 179. Lesions were predominantly present in the frontal and temporal lobes. Unfavourable outcome was present in 67% of the MRI+ group with a significant association of total number of microhaemorrhages in the temporal cortical area on SWI (OR 0.43 (0.21-0.90) p=0.02), with an explained variance of 44%. The number of microhaemorrhages was not correlated with the number of posttraumatic complaints. An unfavourable outcome in the chronic posttraumatic phase is associated with the presence and number of microhaemorrhages in the temporal cortical area. SWI is preferably used to detect these microhaemorrhages.

Early predictors of outcome after mild traumatic brain injury (UPFRONT): an observational cohort study

Mild traumatic brain injury (mTBI) accounts for most cases of TBI, and many patients show incomplete long-term functional recovery. We aimed to create a prognostic model for functional outcome by combining demographics, injury severity, and psychological factors to identify patients at risk for incomplete recovery at 6 months. In particular, we investigated additional indicators of emotional distress and coping style at 2 weeks above early predictors measured at the emergency department. The UPFRONT study was an observational cohort study done at the emergency departments of three level-1 trauma centres in the Netherlands, which included patients with mTBI, defined by a Glasgow Coma Scale score of 13-15 and either post-traumatic amnesia lasting less than 24 h or loss of consciousness for less than 30 min. Emergency department predictors were measured either on admission with mTBI-comprising injury severity (GCS score, post-traumatic amnesia, and CT abnormalities), demographics (age, gender, educational level, pre-injury mental health, and previous brain injury), and physical conditions (alcohol use on the day of injury, neck pain, headache, nausea, dizziness)-or at 2 weeks, when we obtained data on mood (Hospital Anxiety and Depression Scale), emotional distress (Impact of Event Scale), coping (Utrecht Coping List), and post-traumatic complaints. The functional outcome was recovery, assessed at 6 months after injury with the Glasgow Outcome Scale Extended (GOSE). We dichotomised recovery into complete (GOSE=8) and incomplete (GOSE≤7) recovery. We used logistic regression analyses to assess the predictive value of patient information collected at the time of admission to an emergency department (eg, demographics, injury severity) alone, and combined with predictors of outcome collected at 2 weeks after injury (eg, emotional distress and coping). Between Jan 25, 2013, and Jan 6, 2015, data from 910 patients with mTBI were collected 2 weeks after injury; the final date for 6-month follow-up was July 6, 2015. Of these patients, 764 (84%) had post-traumatic complaints and 414 (45%) showed emotional distress. At 6 months after injury, outcome data were available for 671 patients; complete recovery (GOSE=8) was observed in 373 (56%) patients and incomplete recovery (GOSE ≤7) in 298 (44%) patients. Logistic regression analyses identified several predictors for 6-month outcome, including education and age, with a clear surplus value of indicators of emotional distress and coping obtained at 2 weeks (area under the curve [AUC]=0·79, optimism 0·02; Nagelkerke R2=0·32, optimism 0·05) than only emergency department predictors at the time of admission (AUC=0·72, optimism 0·03; Nagelkerke R2=0·19, optimism 0·05). Psychological factors (ie, emotional distress and maladaptive coping experienced early after injury) in combination with pre-injury mental health problems, education, and age are important predictors for recovery at 6 months following mTBI. These findings provide targets for early interventions to improve outcome in a subgroup of patients at risk of incomplete recovery from mTBI, and warrant validation. Dutch Brain Foundation.
