[PMID: 38608468 DOI: 10.1016/j.ajem.2024.04.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Revised: 02/26/2024] [Accepted: 04/01/2024] [Indexed: 04/14/2024] Open
Abstract
BACKGROUND AND OBJECTIVES The incidence of traumatic brain injury (TBI) in older individuals is increasing with an increase in the older population. For older people, the required medical interventions and hospitalization following minor head injury have negative impacts, which have not been reported in literature up till now. We aimed to investigate the risk factors for clinically important traumatic brain injury (ciTBI) in older patients with minor head injury. METHODS This is a retrospective single-center cohort study. Older patients aged ≥65 years presenting with head injury and a Glasgow Coma Scale (GCS) score of ≥13 upon arrival at the hospital between January 1, 2018, and October 31, 2021, were included. Patients with an injury duration of ≥24 h were excluded. The primary outcome was defined as ciTBI (including death, surgery, intubation, medical interventions, and hospital stays of ≥2 nights). Multiple logistic regression analysis was conducted to identify the risk factors. RESULTS A total of 296 patients were included initially, and 6 of them were excluded subsequently. ciTBI was identified in 62 cases. According to the results of the multiple logistic regression analysis, GCS scores of ≤14 (OR 3.72, 95% CI 1.89-7.30), high-risk mechanisms of injury (OR 2.80, 95% CI 1.39-5.64), vomiting (OR 5.01, 95% CI 1.19-21.1), and retrograde amnesia (OR 6.90, 95% CI 3.37-14.1) were identified as risk factors. CONCLUSION In older patients with minor head injury, GCS ≤14, high-risk mechanisms of injury, vomiting, and retrograde amnesia are risk factors for ciTBI.

Abstract
PURPOSE This study examined the research on older adults with a moderate to severe traumatic brain injury (TBI), with a focus on mortality and discharge disposition. METHOD Systematic searches were conducted in MEDLINE, CINAHL, EMBASE and PsycINFO for studies up to April 2022 in accordance with PRISMA guidelines. RESULTS 64 studies, published from 1992 to 2022, met the inclusion criteria. Mortality was higher for older adults ≥60 years old than for their younger counterparts; with a dramatic increase for those ≥80 yr, with rates as high as 93 %. Similar findings were reported regarding mortality in intensive care, surgical mortality, and mortality post-hospital discharge; with an 80 % rate at 1-year post-discharge. Up to 68.4 % of older adults were discharged home; when compared to younger adults, those ≥65 years were less likely to be discharged home (50-51 %), compared to those <64 years (77 %). Older adults were also more likely to be discharged to long-term care (up to 31.6 %), skilled nursing facilities (up to 46.1 %), inpatient rehabilitation (up to 26.9 %), and palliative or hospice care (up to 58 %). CONCLUSION Given their vulnerability, optimizing outcomes for older adults with moderate-severe TBI across the healthcare continuum is critical.

Abstract
The age-standardized incidence of head trauma in 2016 was 369 per 100,000 people worldwide. The Western Pacific region, including Japan, had the highest incidence. This study aimed to extract ICD-10 code data for intracranial injury (S06) and external causes of morbidity and mortality (V01-Y89), analyze their characteristics and interrelationships, and contribute to these diseases' prevention, treatment, and prognosis. The number of deaths according to injury type and external cause type of intracranial injury published by the Japanese government was statistically analyzed using JoinPoint, and univariate distribution and multivariate correlation were conducted using JMP Software. From 1999-2021, there was a downward trend in the number of deaths because of intracranial injuries: mortality from intracranial injuries was higher among those aged ≥65 years. Conversely, mortality from intracranial injuries was lower among those aged ≤14 years. Among deaths from intracranial injury, mortality from diffuse brain injury and traumatic subdural hemorrhage was more common. Among deaths from external causes of intracranial injury, mortality from falls, transport accidents, and other unforeseen accidents was more common. Mortality because of intracranial injuries increased significantly during the 2011 Great East Japan Earthquake. For some age groups and sexes, there were significant inverse correlations of mortality with traumatic subdural hemorrhage and traumatic subarachnoid hemorrhage for transport accidents, intentional self-harm and assault, and diffuse brain injury and focal brain injury for falls. We believe that the data presented in this study will be useful for preventing and treating intracranial injuries and for developing administrative measures to reduce intracranial injuries.

Abstract
BACKGROUND AND OBJECTIVE Ageing is associated with an increased risk of falls and trauma. The aim of the study was to assess the characteristics of patients over 65 years of age who consulted the ED for traumatic brain injury (TBI) in 2022, their relationship with cognitive impairment, functional dependence, use of oral antiplatelet/anticoagulant drugs and complications. MATERIALS AND METHODS Retrospective study conducted from 1 January to 31 December 2022. Demographic data were collected: age, sex, origin; cardiovascular risk factors; cognitive impairment using the Pfeiffer questionnaire; physical disability according to the Barthel Index; number of drugs; use of antiplatelet and oral anticoagulant (OAC); mechanism of fall; performance of cranial X-ray/CT, and presence of complications: intracranial haemorrhage (ICH), death. RESULTS 599 patients were included. The mean age was 82.3±8.2 years. 63.8% were female and 36.2% male. 75.3% were from home, 24.7% from residence. No dementia in 61.4%, moderate-severe dementia in 38.6%. 58.1% were functionally independent, 25.1% had moderate-severe dependence. 85.7% had CVRF: HT 476 (79.5%), dyslipidaemia 354 (59.1%), DM 217 (36.2%), obesity 173 (28.9%), smoking 15 (2.5%). The number of drugs per patient was 9.2±4.3. Polypharmacy was present in 94.7% of patients. 35.9% were taking antiplatelet drugs and 30.2% anticoagulants. Intracranial haemorrhage occurred in 11 (2.3%) patients. Four (0.7%) patients died. CONCLUSIONS The TBI in our study was caused by low-energy trauma in a female patient, without dementia, functionally independent and with polypharmacy. There were few serious complications: 2.3% ICH and 0.7% deaths. 90.1% of ICH occurred in patients on antiplatelet and/or OAC therapy.

Is There an Optimal Time Window of Placement of Intracranial Pressure (ICP) Monitor for Elderly Patients With Severe Traumatic Brain Injury? An 11-Year Institutional Cohort Study With Restricted Cubic Spline Analysis. J Neurotrauma 2024.

Abstract
Severe traumatic brain injury (sTBI) is a prominent contributor to both morbidity and mortality in the elderly population. The monitoring of intracranial pressure (ICP) is crucial in the management of sTBI patients. Nevertheless, the appropriate timing for the placement of ICP monitor in elderly sTBI patients remains uncertain. To determine the optimal timing for the placement of ICP monitor in elderly sTBI patients, in this retrospective cohort study, we collected data from elderly patients (> 65 years) who suffered sTBI and received ICP monitors at Tangdu Hospital, The Fourth Military Medical University, between January 2011 and December 2021. To examine the relationship between the time of ICP monitor placement and in-hospital mortality, we conducted a multi-variate-adjusted restricted cubic spline (RCS) analysis. Additionally, logistic regression analysis was applied to further analyze the influencing factors contributing to early or late ICP monitor placements. A total of 283 eligible elderly TBI patients were included in the current analysis. The in-hospital mortality rate was 73 out of 283 (26%). The RCS analysis demonstrated an inverted U-shaped curve in the relationship between the timing of ICP monitor placement and in-hospital mortality. For the elderly sTBI patient cohort, 6 h was identified as the crucial moment for the treatment strategy. In addition, the protective time window for ICP placement was less than 4.92 h for the GCS 3-5 group, and less than 8.26 h for the GCS 6-8 group. However, the clinical benefit of ICP placement decreased gradually over time. The relationship between ICP placement and in-hospital mortality was non-linear, exhibiting an inverted U-shaped curve in elderly patients with sTBI. For elderly patients with sTBI, early (≤ 6 h) ICP placement was associated with reduced in-hospital mortality. The clinical benefit of ICP placement decreased beyond the optimal time window.

Abstract
OBJECTIVE This study aims to identify risk factors for central nervous system (CNS) infection in elderly patients hospitalized with traumatic brain injury (TBI) and to develop a reliable predictive tool for assessing the likelihood of CNS infection in this population. METHOD We conducted a retrospective study on 742 elderly TBI patients treated at Tangdu Hospital, China. Clinical data was randomly split into training and validation sets (7:3 ratio). By conducting univariate and multivariate logistic regression analysis in the training set, we identified a list of variables to develop a nomogram for predicting the risk of CNS infection. We evaluated the performance of the predictive model in both cohorts respectively, using receiver operating characteristics curves, calibration curves, and decision curve analysis. RESULTS Results of the logistic analysis in the training set indicated that surgical intervention (P = 0.007), red blood cell count (P = 0.019), C-reactive protein concentration (P < 0.001), and cerebrospinal fluid leakage (P < 0.001) significantly predicted the occurrence of CNS infection in elderly TBI patients. The model constructed based on these variables had high predictive capability (area under the curve-training = 0.832; area under the curve-validation = 0.824) as well as clinical utility. CONCLUSIONS A nomogram constructed based on several key predictors reasonably predicts the risk of CNS infection in elderly TBI patients upon hospital admission. The model of the nanogram may contribute to timely interventions and improve health outcomes among affected individuals.

Front Med (Lausanne) 2023; 10:1290201. [PMID: 38152301 PMCID: PMC10751787 DOI: 10.3389/fmed.2023.1290201] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Accepted: 11/02/2023] [Indexed: 12/29/2023] Open
Abstract
Introduction The elderly population constitutes one of the fastest-growing demographic groups globally. Within this population, mild to moderate traumatic brain injuries (TBI) resulting from ground level falls (GLFs) are prevalent and pose significant challenges. Between 50 and 80% of TBIs in older individuals are due to GLFs. These incidents result in more severe outcomes and extended recovery periods for the elderly, even when controlling for injury severity. Given the increasing incidence of such injuries it becomes essential to identify the key factors that predict complications and in-hospital mortality. Therefore, the aim of this study was to pinpoint the top predictors of complications and in-hospital mortality in geriatric patients who have experienced a moderate TBI following a GLF. Methods Data were obtained from the American College of Surgeons' Trauma Quality Improvement Program database. A moderate TBI was defined as a head AIS ≤ 3 with a Glasgow Coma Scale (GCS) 9-13, and an AIS ≤ 2 in all other body regions. Potential predictors of complications and in-hospital mortality were included in a logistic regression model and ranked using the permutation importance method. Results A total of 7,489 patients with a moderate TBI were included in the final analyses. 6.5% suffered a complication and 6.2% died prior to discharge. The top five predictors of complications were the need for neurosurgical intervention, the Revised Cardiac Risk Index, coagulopathy, the spine abbreviated injury severity scale (AIS), and the injury severity score. The top five predictors of mortality were head AIS, age, GCS on admission, the need for neurosurgical intervention, and chronic obstructive pulmonary disease. Conclusion When predicting both complications and in-hospital mortality in geriatric patients who have suffered a moderate traumatic brain injury after a ground level fall, the most important factors to consider are the need for neurosurgical intervention, cardiac risk, and measures of injury severity. This may allow for better identification of at-risk patients, and at the same time resulting in a more equitable allocation of resources.

Abstract
Use of anticoagulants is increasing with the aging of societies. The safe first-line drug is likely to be a direct oral anticoagulant (DOAC), but outcomes of treatment of traumatic brain injury (TBI) with anticoagulants are uncertain. Therefore, we examined the clinical effect of idarucizumab as reversal therapy in elderly patients with TBI who were treated with dabigatran. A retrospective multi-center observational study was performed in patients ≥65 years of age who developed acute traumatic subdural hematoma during treatment with dabigatran and underwent reversal therapy with idarucizumab. The items examined included patient background, neurological and imaging findings at arrival, course after admission, complications, and outcomes. A total of 23 patients were enrolled in the study. The patients had a mean age of 78.9 years. Cause of TBI was fall in 60.9% of the subjects. Mean Glasgow Coma Scale score at arrival was 8.7; anisocoria was present in 31.8% of cases. Exacerbation of consciousness was found in 30.4%, but only in 13.3% of subjects treated with idarucizumab before consciousness and imaging findings worsened. Dabigatran was discontinued in 81.8% of cases after hematoma development, with a mean withdrawal period of 12.1 days. The favorable outcome rate was 21.7%, and mortality was 39.1%. In multi-variate analysis, timing of idarucizumab administration was associated with a favorable outcome. There were ischemic complications in 3 cases (13.1%), and all three events occurred ≥7 days after administration of idarucizumab. These findings suggest that in cases that develop hematoma during treatment with dabigatran, it is important to administer idarucizumab early and restart dabigatran after conditions stabilize.

Abstract
BACKGROUND Some patients with subdural hematoma (SDH) with acute extra-arachnoid lesions and without concomitant subarachnoid blood or contusions may present in similarly grave neurological condition compared with the general population of patients with SDH. However, these patients often make an impressive neurological recovery. This study compared neurological outcomes in patients with extra-arachnoid SDH with all other SDH patients. METHODS We compared a prospective series of extra-arachnoid SDH patients without subarachnoid hemorrhage or other concomitant intracranial injury with a Transforming Research and Clinical Knowledge in TBI control group with SDH only. We performed inverse probability weighting for key characteristics and ordinal regression with and without controlling for midline shift comparing neurological outcomes (Extended Glasgow Outcome Scale score) at 2 weeks. We used the Corticosteroid Randomization After Significant Head Injury prognostic model to predict mortality based on age, Glasgow Coma Scale score, pupil reactivity, and major extracranial injury. RESULTS Mean midline shift was significantly different between extra-arachnoid SDH and control groups (7.2 mm vs. 2.7 mm, P < 0.001). After weighting for group allocation and controlling for midline shift, extra-arachnoid SDH patients had 5.68 greater odds (P < 0.001) of a better 2-week Extended Glasgow Outcome Scale score than control patients. Mortality in the extra-arachnoid SDH group was less than predicted by the Corticosteroid Randomization After Significant Head Injury prognostic model (10% vs. 21% predicted). CONCLUSIONS Patients with extra-arachnoid SDH have significantly better 2-week neurological outcomes and lower mortality than predicted by the Corticosteroid Randomization After Significant Head Injury model. Neurosurgeons should consider surgery for this patient subset even in cases of poor neurological examination, older age, and large hematoma with high degree of midline shift.

Abstract
Older adults account for a disproportionate share of the morbidity and mortality after traumatic brain injury (TBI). Predicting functional and cognitive outcomes for individual older adults after TBI is challenging in the acute phase of injury. Given that neurologic recovery is possible and uncertain, life-sustaining therapy may be pursued initially, even if for some, there is a risk of survival to an undesired level of disability or dependence. Experts recommend early conversations about goals of care after TBI, but evidence-based guidelines for these discussions or for the optimal method for communicating prognosis are limited. The time-limited trial (TLT) model may be an effective strategy for managing prognostic uncertainty after TBI. TLTs can provide a framework for early management: specific treatments or procedures are used for a defined period of time while monitoring for an agreed-upon outcome. Outcome measures, including signs of worsening and improvement, are defined at the outset of the trial. In this Viewpoint article, we discuss the use of TLTs for older adults with TBI, their potential benefits, and current challenges to their application. Three main barriers limit the implementation of TLTs in these scenarios: inadequate models for prognostication; cognitive biases faced by clinicians and surrogate decision-makers, which may contribute to prognostic discordance; and ambiguity regarding appropriate endpoints for the TLT. Further study is needed to understand clinician behaviors and surrogate preferences for prognostic communication and how to optimally integrate TLTs into the care of older adults with TBI.

Abstract
INTRODUCTION A difficult question in autopsy practice is whether intracranial haemorrhage has resulted from or brought about a fall. MATERIAL AND METHODS To address this we undertook a retrospective study of all autopsy reports (N = 2126) complied over a 10 year period (2009-2018). Of 720 patients who underwent a comprehensive post mortem neuropathologic examination we found 226 patients who had a history of a fall. RESULTS Of the 226 with a history of fall, 175 (79%) had an intracranial haemorrhage which was classified as truamatic (n = 134, 77%) or spontaneous (n = 41, 23%. Within the traumatic group, falls from a standing height (51%) were more common than falls involving stairs (31%) or falls from a height (12%). Cerebral contusional injury (51%) and subdural haemorrhage (45%) were the most common type of haemorrhage in the traumatic group. In the spontaneous haemorrhage group cerebral amyloid angiopathy (49%) was the commonest detected cause and was typically lobar in distribution). CONCLUSION We are of the view that a comprehensive analysis of fatal falls with intracranial haemorrhage warrants a detailed neuropathologic examination as part of the overall death analysis.

Abstract
Background Anticoagulants prevent thrombosis in patients with atrial fibrillation (AF) and venous thromboembolism but increase the risk of hemorrhagic complications. If severe bleeding occurs with anticoagulant use, discontinuation and rapid reversal are essential. However, the optimal timing for resuming anticoagulants after using reversal agents remains unclear. Here, we report early cerebral infarction following the use of andexanet alfa (AA), a specific reversal agent for factor Xa inhibitors, in a patient with traumatic acute subdural hematoma (ASDH). The possible causes of thromboembolic complication and the optimal timing for anticoagulant resumption are discussed. Case Description An 84-year-old woman receiving rivaroxaban for AF presented with impaired consciousness after a head injury. Computed tomography (CT) revealed right ASDH. The patient was administered AA and underwent craniotomy. Although the hematoma was entirely removed, she developed multiple cerebral infarctions 10 h after the surgery. These infarctions were considered cardiogenic cerebral embolisms and rivaroxaban was therefore resumed on the same day. This case indicates the possibility of early cerebral infarction after using a specific reversal agent for factor Xa inhibitors. Conclusion Most studies suggest that the safest time for resuming anticoagulants after using reversal agents is between 7 and 12 days. The present case showed that embolic complications may develop much earlier than expected. Early readministration of anticoagulant may allow for adequate prevention of the acute thrombotic syndromes.

Abstract
Background Traumatic brain injury (TBI) is one of the most common trauma-related diagnoses among the elderly population treated in emergency departments (ED). Identification of patients with increased or decreased risk of intracranial bleeding is of clinical importance. The objective of this study was to evaluate the implication of cutaneous impact location (CIL) on the prevalence of intracranial injury after suspected or confirmed TBI irrespective of its severity. Methods This was a retrospective, single-center, descriptive observational study of geriatric patients aged 65 years and older treated for suspected or confirmed TBI in a trauma surgery ED. The primary outcome of the study was the assessment of a CIL of the injury and its association with the prevalence of intracranial lesions found on a head computed tomography scan. Results Among 381 patients included in the analysis, the CIL of interest (temporo-parietal and occipital impacts) was present among 178 (46.7%) cases. Thirty-six (9.5%) patients were diagnosed with intracranial bleeding. The prevalence of intracranial bleeding was higher in the CIL of interest group compared with other locations outside (12.9% vs 6.4%; p = 0.030). CIL of interest was a predictor of intracranial bleeding (p = 0.033; OR: 2.17; 95% CI: 1.06 to 4.42). Conclusion The CIL of head injury is a predictor of intracranial lesions among geriatric patients with traumatic brain injury. Physicians should be aware of this association when assessing elderly patients with head injuries. More studies are needed to develop a clinical management tool incorporating CIL to guide the diagnosis of TBI in this population.

Abstract
BACKGROUND As the population worldwide is aging, the need for surgery in elderly patients with neurotrauma is increasing. The aim of this study was to compare the outcome of elderly patients undergoing surgery for neurotrauma with younger patients and to identify the risk factors for mortality. METHODS We retrospectively analyzed consecutive patients undergoing craniotomy or craniectomy for neurotrauma at our institution from 2012 to 2019. Patients were divided into two groups (≥70 years or <70 years) and compared. The primary outcome was the 30-day mortality rate. Potential risk factors for 30-day mortality were assessed in a uni- and multivariate regression model for both age groups, forming the basis of a 30-day mortality prediction score. RESULTS We included 163 consecutive patients (average age 57.98 ± 19.87 years); 54 patients were ≥70 years. Patients ≥70 years showed a significantly better median preoperative Glasgow Coma Scale (GCS) score compared with young patients (P < 0.001), and fewer pupil asymmetry (P = 0.001), despite having a higher Marshall score (P = 0.07) at admission. Multivariate regression analysis identified low pre- and postoperative GCS scores and the lack of prompt postoperative prophylactic low-molecular-weight heparin treatment as risk factors for 30-day mortality. Our score showed moderate accuracy in predicting 30-day mortality with an area under the curve of 0.76. CONCLUSIONS Elderly patients after neurotrauma present with a better GCS at admission despite having more severe radiographic injuries. Mortality and favorable outcome rates are comparable between the age groups.

Abstract
Importance Firearm injuries are associated with devastating visual outcomes. Several studies have demonstrated disparities in trauma care and discharge to rehabilitation and other advanced care facilities (ACFs) due to race and ethnicity and insurance status. The identification of possible disparities in disposition of patients admitted with firearms-associated ocular injuries (FAOIs) is a crucial step in moving toward health equity. Objective To describe disposition patterns following admission for FAOI trauma. Design, Setting, and Participants This retrospective analysis of National Trauma Data Bank (NTDB) from 2008 through 2014 used hospitalized trauma cases from over 900 US facilities detailed in the NTDB. Participants included patients admitted with ocular injuries. Statistical analysis was conducted between April 16, 2017, and December 15, 2021. Exposure Firearm injuries. Main Outcomes and Measures Patients admitted with FAOIs were identified using International Classification of Diseases, Ninth Revision, Clinical Modification diagnostic codes and E-codes. Demographic data, location, injury type and severity, and insurance status were documented. The primary outcome was the odds of discharge to ACFs. Results A total of 8715 of 235 254 firearms injuries involved the eye (3.7%). Of the 8715 included patients, 7469 were male (85.7%), 3050 were African American (35.0%), and 4065 White (46.6%), with a mean (SD) age of 33.8 (16.9) years. Common payments were government insurance (31.5%), self-paid insurance (29.4%), and commercial insurance plans (22.8%). Frequent dispositions were home (48.8%) and ACF (20.5%). Multivariate analysis demonstrated that the following factors were associated with the highest odds of discharge to an ACF: hospital stays 6 days or longer (odds ratio [OR], 3.05; 95% CI, 2.56-3.63; P < .001), age 65 years or older (OR, 2.94; 95% CI, 1.94-4.48; P < .001), associated traumatic brain injury (OR, 2.32; 95% CI, 1.94-2.78; P < .001), severe traumatic brain injury (OR, 2.10; 95% CI, 1.79-2.46; P < .001), and very severe Injury Severity Score (OR, 2.22; 95% CI, 1.88-2.62; P < .001). White race (OR, 2.00; 95% CI, 1.71-2.33; P < .001) was associated with higher odds than Medicare insurance (OR, 1.64; 95% CI, 1.16-2.31; P = .01). Conclusions and Relevance These findings suggest that older, more severely injured, Medicare-insured, or White patients have higher odds of ACF placement than younger, less severely injured, otherwise insured, and Black and Hispanic patients. This study is limited by its retrospective nature and the study team was unable to explore the basis for these disposition differences. Nevertheless, this work highlights that disparities may exist in disposition after FAOIs that may limit the rehabilitation potential of specific populations.

Abstract
INTRODUCTION Elderly patients receiving antithrombotic treatment have a significantly higher risk of developing an intracranial hemorrhage when suffering traumatic brain injury (TBI), potentially contributing to higher mortality rates and worse functional outcomes. It is unclear whether different antithrombotic drugs carry a similar risk. OBJECTIVE This study aims to investigate injury patterns and long-term outcomes after TBI in elderly patients treated with antithrombotic drugs. METHODS The clinical records of 2999 patients ≥ 65 years old admitted to the University Hospitals Leuven (Belgium) between 1999 and 2019 with a diagnosis of TBI, spanning all injury severities, were manually screened. RESULTS A total of 1443 patients who had not experienced a cerebrovascular accident prior to TBI nor presented with a chronic subdural hematoma at admission were included in the analysis. Relevant clinical information, including medication use and coagulation lab tests, was manually registered and statistically analyzed using Python and R. In the overall cohort, 418 (29.0%) of the patients were treated with acetylsalicylic acid before TBI, 58 (4.0%) with vitamin K antagonists (VKA), 14 (1.0%) with a different antithrombotic drug, and 953 (66.0%) did not receive any antithrombotic treatment. The median age was 81 years (IQR = 11). The most common cause of TBI was a fall accident (79.4% of the cases), and 35.7% of the cases were classified as mild TBI. Patients treated with vitamin K antagonists had the highest rate of subdural hematomas (44.8%) (p = 0.02), hospitalization (98.3%, p = 0.03), intensive care unit admissions (41.4%, p < 0.01), and mortality within 30 days post-TBI (22.4%, p < 0.01). The number of patients treated with adenosine diphosphate (ADP) receptor antagonists and direct oral anticoagulants (DOACs) was too low to draw conclusions about the risks associated with these antithrombotic drugs. CONCLUSION In a large cohort of elderly patients, treatment with VKA prior to TBI was associated with a higher rate of acute subdural hematoma and a worse outcome, compared with other patients. However, intake of low dose aspirin prior to TBI did not have such effects. Therefore, the choice of antithrombotic treatment in elderly patients is of utmost importance with respect to risks associated with TBI, and patients should be counselled accordingly. Future studies will determine whether the shift towards DOACs is mitigating the poor outcomes associated with VKA after TBI.

Abstract
BACKGROUND Recovery after traumatic brain injury (TBI) in older adults is usually affected by the presence of comorbidities, leading to more severe sequelae in this age group than in younger patients. However, there are only few reports that prospectively perform in-depth assessment of outcome following TBI in elderly. OBJECTIVE This study aims at documenting structural brain characteristics and functional outcome and quality of life in elderly patients 6 months after TBI and comparing these data with healthy volunteers undergoing the same assessments. METHODS Thirteen TBI patients ≥ 65 years old, admitted to the University Hospitals Leuven (Belgium), between 2019 and 2022 due to TBI, including all injury severities, and a group of 13 healthy volunteers with similar demographic characteristics were prospectively included in the study. At admission, demographic, injury, and CT scan data were collected in our database. Six months after the accident, a brain MRI scan and standardized assessments of frailty, sleep quality, cognitive function, motor function, and quality of life were conducted. RESULTS A total of 13 patients and 13 volunteers were included in the study, with a median age of 74 and 73 years, respectively. Nine out of the 13 patients presented with a mild TBI. The patient group had a significantly higher level of frailty than the control group, presenting a mean Reported Edmonton Frailty Scale score of 5.8 (SD 2.7) vs 0.7 (SD 1.1) (p < 0.01). No statistically significant differences were found between patient and control brain volumes, fluid attenuated inversion recovery white matter hyperintensity volumes, number of lesions and blackholes, and fractional anisotropy values. Patients demonstrated a significantly higher median reaction time in the One Touch Stockings of Cambridge (22.3 s vs 17.6, p = 0.03) and Reaction Time (0.5 s vs 0.4 s, p < 0.01) subtests in the Cambridge Neuropsychological Test Automated Battery. Furthermore, patients had a lower mean score on the first Box and Blocks test with the right hand (46.6 vs 61.7, p < 0.01) and a significantly higher mean score in the Timed-Up & Go test (13.1 s vs 6.2 s, p = 0.02) and Timed Up & Go with cognitive dual task (16.0 s vs 10.2 s, p < 0.01). Substantially lower QOLIBRI total score (60.4 vs 85.4, p < 0.01) and QOLIBRI-OS total score (53.8 vs 88.5, p < 0.01) were also observed in the patients' group. CONCLUSION In this prospective study, TBI patients ≥ 65 years old when compared with elder controls showed slightly worse cognitive performance and poorer motor function, higher fall risk, but a substantially reduced QoL at 6 months FU, as well as significantly higher frailty, even when the TBI is classified as mild. No statistically significant differences were found in structural brain characteristics on MRI. Future studies with larger sample sizes are needed to refine the impact of TBI versus frailty on function and QoL in elderly.

Abstract
Head trauma and delirium are two common conditions in the elderly population. They both carry a heavy burden in terms of mortality and morbidity and are associated with one another through several environmental and clinical factors, such as comorbidities, age, and sex. One factor that may play a role in both these conditions is inflammation, which might also represent a link between them. In particular, head trauma can cause both systemic and neuroinflammation, while delirium appears to be precipitated by inflammatory conditions, while also involving a number of inflammatory pathways in its pathogenesis. Interleukin 6 and tumor necrosis factor α are only two of the main actors in this crosstalk, which also involves microglia and immune cells. An indirect proof is that anti-inflammatory drugs have proven effective in reducing post-traumatic delirium, thus demonstrating the importance of inflammation in the pathophysiology of this disease. In this paper, we have revised the available literature exploring the links between inflammation, head trauma and delirium and we will discuss the mechanisms of this relationship, paying particular attention to the possible future implications.

Abstract
Domestic cow-related injuries can carry significant morbidity and mortality among livestock farmers. We report a case of an 83-year-old male farmer with severe facial trauma and a potentially compromised airway caused by a domestic dairy cow during his routine work while taking oral anticoagulants. Since head and neck trauma caused by domestic cows can be severe, preventive measures should be taken to protect cattle farmers in those exposed areas.

Abstract
OBJECTIVE Cognitive symptoms are common in the initial weeks after mTBI, but recovery is generally expected within three months. However, there is limited information about recovery specifically in older age cohorts. Therefore, this study investigated cognitive outcome three months after mTBI in older adults (≥ 65 years) compared to trauma and community age-matched controls and explored risk factors for outcome after traumatic injury. METHODS Older mTBI patients (n = 40) and older adults with mild traumatic injury but without head injury (n = 66) were compared to a noninjured community control group (n = 47). Cognitive assessment included neuropsychological and computerized tests. Group differences were compared on individual tasks and overall cognitive performances using composite scores. Regression analyses identified predictors of outcome for trauma patients and moderator analyses explored possible interactions of mTBI severity with age and cognition. RESULTS As well as lower performances in processing speed and memory, both trauma groups had significantly lower performance on composite neuropsychological (d = .557 and .670) and computerized tasks (d = .783 and .824) compared to noninjured controls. Age, education, and history of depression were direct predictors of cognitive performance after mild traumatic injury (with or without head injury). Further moderation analysis demonstrated that mTBI severity (Glasgow Coma Scale < 15) moderated the impact of older age on computerized assessment (β = -.138). CONCLUSIONS Three months after mild trauma (regardless of head injury), older people demonstrate lower cognition compared to noninjured peers. However, severity of mTBI (Glasgow Coma Scale < 15) can interact with older age to predict poorer cognitive outcomes.

Abstract
Background Skiing is a very popular sport worldwide, with increasing trends over the past decades. This study aimed to evaluate the importance of traumatic brain injury (TBI), especially in the elderly, after a ski accident, and to describe its short-term repercussions. Methodology Patients were analyzed who were admitted to our neurotrauma center from 2012–2018 after a head trauma while skiing. Three different age groups were differentiated and analyzed for the severity of TBI depending on the initial Glasgow Coma Scale as the primary outcome and as secondary outcomes need and type of surgery, Glasgow Outcome Score, preexisting use of anticoagulant or antiplatelet drugs, time to presentation, and pattern of brain injury. TBI severity was adjusted to the time to initial medical consultation. Results No significant difference in TBI severity was found when comparing the middle (>29–54) and older (≥54) age groups to the reference group <30 years (OR:0.45, p = 0.127; OR:0.46, p = 0.17). Acute subdural hemorrhage was present in 21.2% of the ≥55 group and 14.5% of the 30–54 age group, compared to 12.8% of the youngest group (p = <0.001). Overall, 39.4% of the patients in the ≥55 group and 8.1% of the 30–54 age group presented with chronic subdural hemorrhage, whereas none of the youngest patients did (p = <0.001). Conclusion No differences were observed in terms of TBI severity between age groups after acute trauma. Nonetheless, a different pattern of head injury after TBI in older patients was demonstrated. Accordingly, the management differs for these TBIs compared to those of younger patients.

Abstract
OBJECTIVE Older age is often identified as a risk factor for poor outcome from traumatic brain injury (TBI). However, this relates predominantly to mortality following moderate-severe TBI. It remains unclear whether increasing age exerts risk on the expected recovery from mild TBI (mTBI). In this systematic review of mTBI in older age (60+ years), a focus was to identify outcome through several domains - cognition, psychological health, and life participation. METHODS Fourteen studies were identified for review, using PRISMA guidelines. Narrative synthesis is provided for all outcomes, from acute to long-term time points, and a meta-analysis was conducted for data investigating life participation. RESULTS By 3-month follow-up, preliminary findings indicate that older adults continue to experience selective cognitive difficulties, but given the data it is possible these difficulties are due to generalised trauma or preexisting cognitive impairment. In contrast, there is stronger evidence across time points that older adults do not experience elevated levels of psychological distress following injury and endorse fewer psychological symptoms than younger adults. Meta-analysis, based on the Glasgow Outcome Scale at 6 months+ post-injury, indicates that a large proportion (67%; 95% CI 0.569, 0.761) of older adults can achieve good functional recovery, similar to younger adults. Nevertheless, individual studies using alternative life participation measures suggest more mixed rates of recovery. CONCLUSIONS Although our initial review suggests some optimism in recovery from mTBI in older age, there is an urgent need for more investigations in this under-researched but growing demographic. This is critical for ensuring adequate health service provision, if needed.

Abstract
BACKGROUND Patients sustaining critical TBI [initial Glasgow Coma Scale (GCS) ≤ 5] generally have poor outcomes. Little is known about the frequency, mortality rate, and functional outcomes of such patients in Iran. METHODS In this retrospective, registry-based cohort study, the demographic and clinicoradiological findings of TBI patients were queried from March 21, 2017, to March 21, 2020. We included TBI patients with initial GCS of 3-5. The functional outcome was assessed using the Glasgow Outcome Score-extended 6 (GOSE-6) months after the hospital discharge. Patients were classified as having unfavorable (GOSE-6 ≤ 4) and favorable (GOSE-6 > 4) outcomes. Gathered data were compared between groups. Multivariable logistic regression analysis was done to find factors affecting the outcome. RESULTS Four hundred ninety-seven patients (mean age = 37.59 ± 17.89) were enrolled, and 69.2% had unfavorable outcomes. Elderly patients (age ≥ 65 years) were highly overrepresented among the unfavorable group. 48.9% had bilateral fixed dilated pupils (BDFP), who mostly attained unfavorable outcomes. The overall in-hospital mortality rate was 50.3%. The in-hospital mortality rate was appalling among elderly patients with BFDP and GCS 3( 90%) and GCS 4(100%). Age ≥ 65 years [odds ratio (OR) 3.45, 95% confidence interval (CI) 1.19-10.04], and BFDP (OR 4.48, 95% CI 2.60-7.73) increase the odds of unfavorable outcomes according to the regression analysis. CONCLUSION The survival rate and favorable outcomes of critical TBI patients are generally poor. However, we believe that the neurotrauma surgeons should discuss with patients' proxies and explain the clinical conditions and possible outcomes.

Abstract
OBJECTIVES This review aimed to identify the demographic and clinical differences between those older adults admitted directly under neurosurgical care and those that were not, and whether EMS clinicians could use these differences to improve patient triage. METHODS The authors searched for papers that included older adults who had suffered a TBI and were either admitted directly under neurosurgical care or were not. Titles and abstracts were screened, shortlisting potentially eligible papers before performing a full-text review. The Newcastle-Ottawa Scale was used to assess the risk of bias. RESULTS A total of nine studies were eligible for inclusion. A high abbreviated injury score head, Marshall score or subdural hematoma greater than 10 mm were associated with neurosurgical care. There were few differences between those patients who did and did not receive neurosurgical intervention. CONCLUSIONS Absence of guidelines and clinician bias means that differences between those treated aggressively and conservatively observed in the literature are fraught with bias. Further work is required to understand which patients would benefit from an escalation of care and whether EMS can identify these patients so they are transported directly to a hospital with the appropriate services on-site.

Abstract
BACKGROUND Mortality caused by Traumatic Brain Injury (TBI) remains high, despite improvements in trauma and critical care. Polytrauma is naturally associated with high mortality. This study compared mortality rates between isolated TBI (ITBI) patients and polytrauma patients with TBI (PTBI) admitted to ICU to investigate if concomitant injuries lead to higher mortality amongst TBI patients. METHODS A 3-year cohort study compared polytrauma patients with TBI (PTBI) with AIS head ≥3 (and AIS of other body regions ≥3) from a prospective collected database to isolated TBI (ITBI) patients from a retrospective collected database with AIS head ≥3 (AIS of other body regions ≤2), both admitted to a single level-I trauma center ICU. Patients <16 years of age, injury caused by asphyxiation, drowning, burns and ICU transfers from and to other hospitals were excluded. Patient demographics, shock and resuscitation parameters, multiple organ dysfunction syndrome (MODS), acute respiratory distress syndrome (ARDS), and mortality data were collected and analyzed for group differences. RESULTS 259 patients were included; 111 PTBI and 148 ITBI patients. The median age was 54 [33-67] years, 177 (68%) patients were male, median ISS was 26 [20-33]. Seventy-nine (31%) patients died. Patients with PTBI developed more ARDS (7% vs. 1%, p = 0.041) but had similar MODS rates (18% vs. 10%, p = 0.066). They also stayed longer on the ventilator (7 vs. 3 days, p=<0.001), longer in ICU (9 vs. 4 days, p=<0.001) and longer in hospital (24 vs. 11 days, p=<0.001). TBI was the most prevalent cause of death in polytrauma patients. Patients with PTBI showed no higher in-hospital mortality rate. Moreover, mortality rates were skewed towards ITBI patients (24% vs. 35%, p = 0.06). DISCUSSION There was no difference in mortality rates between PTBI and ITBI patients, suggesting TBI-severity as the predominant factor for ICU mortality in an era of ever improving acute trauma care.

Abstract
OBJECTIVE As the global population ages, the incidence of traumatic brain injury (TBI) increases. While mild TBI can impair the cognitive function of older adults, the cause and background of mild TBI-induced cognitive impairment remains unclear, and the evaluation of risk factors for cognitive impairment after mild TBI remain open for consideration especially in the current aging society. This study aimed to evaluate the risks associated with cognitive impairment following mild TBI. METHODS Between January 2006 and December 2018, 2,209 patients with TBI required hospitalization in Shimane Prefectural Central Hospital. Mild TBI was defined as a Japan coma scale ≤ 10 at admission. The cognitive function of the patients was measured with the Hasegawa Dementia Rating Scale-revised or Mini-mental state examination at least twice during the patients' hospital stays. The odds ratio (OR) and 95% confidence interval (CI) of each considered risk factor was calculated with multivariable logistic regression analysis after univariate analysis. RESULTS Among 1,674 patients with mild TBI, 172 patients underwent cognitive function examinations, and 145 patients (84.3%) were found to have cognitive impairment at discharge. Significant risk factors for cognitive impairment included age (P = 0.008) and hypertension (P = 0.013) in univariate analysis; and age (OR 1.04: 95% CI 1.01-1.07) and hypertension (OR 5.81: 95% CI 1.22-27.68) by multivariable analysis. CONCLUSIONS Older patients with hypertension displayed significantly higher cognitive impairment risk after even mild TBI. For these patients, we should take carefully management even after mild TBI.

Surgical safety criteria for burr hole surgery with urokinase in patients with acute subdural hematoma: Retrospective comparison between burr hole surgery and craniotomy. Surg Neurol Int 2021; 12:574.

Abstract
Background: Acute subdural hematoma (ASDH) is a common disease and craniotomy is the first choice for removing hematoma. However, patients for whom craniotomy or general anesthesia is contraindicated are increasing due to population aging. In our department, we perform burr hole surgery under local anesthesia with urokinase administration for such patients. We compared the patient background and outcomes between burr hole surgery and craniotomy to investigate the surgical safety criteria for burr hole surgery. Methods: We reviewed 24 patients who underwent burr hole surgery and 33 patients who underwent craniotomy between January 2010 and April 2020 retrospectively. Results: The median age of the burr hole surgery group was older (P = 0.01) and they had multiple pre-existing conditions. Compared with the craniotomy group, neurological deficits and CT findings were minor in the burr hole surgery group, whereas the maximum hematoma thickness was not significantly different. The hematoma was excreted after a total of 54,000 IU of urokinase was administered for a median of 3 days. The Glasgow Coma Scale score improved in all patients in the burr hole surgery group and there were no deaths. Age, especially over 65 y.o., (OR 1.16, 95% CI 1.04–1.30) and the absence of basal cistern disappearance (OR 0.04, 95% CI 0.004–0.39) were significant factors. Conclusion: Burr hole surgery was performed safely in all patients based on the age, especially older than 65 y.o., and the absence of basal cistern disappearance. ASDH in the elderly is increasing and less invasive burr hole surgery with urokinase is suitable for the super-aging society.

Abstract
OBJECTIVE Examine effects of age cohort on post-injury life satisfaction in elderly persons with TBIDesign: Retrospective cohortSetting: TBI Model Systems centers. PARTICIPANTS 5,109 elderly participants with TBI in the TBI Model Systems National DatabaseInterventions: Not applicableMain Outcome Measures: Demographics, injury characteristics and cause, outcomes, age at time of analysis, time to follow commands, maximum follow-up period, and scores on the Satisfaction With Life Scale (SWLS) and Participation Assessment with Recombined Tools-Objective (PART-O) scores at 1, 2, 5, or 10 years post-injury. RESULTS Life satisfaction post-TBI across groups increased with age. The young-old sub-group demonstrated the poorest life satisfaction outcomes, while the oldest sub-group experienced greatest life satisfaction. In contrast, participation decreased with age. CONCLUSIONS Findings show diversity in satisfaction with life following moderate to severe TBI for three elderly age-cohorts. Differences may be due to variations in generation-based lived experience, in perceived meaningfulness of participation, could echo prior evidence of greater resilience in the oldest group, or could reflect bias within the study sample. Further research into between- and within- differences for elderly TBI age cohorts is needed to more precisely meet their needs for physical and functional rehabilitation as well as psychological supports.

Abstract
OBJECTIVES This study evaluated the impact of a 12-week, 24-session multimodal group cognitive rehabilitation intervention, the Cognitive Enrichment Program (CEP), on executive functioning and resumption of daily activities after traumatic brain injury (TBI) in older individuals as compared with an active control group that received individual holistic rehabilitation as usual care. METHODS In total, 37 patients with a TBI and aged 57 to 90 years were assigned to experimental (n = 23) and control (n = 14) groups in a semi-randomized, controlled, before-after intervention trial with follow-up at 6 months, with blinded outcome measurement. The CEP's executive function module included planning, problem solving, and goal management training as well as strategies focusing on self-awareness. Efficacy was evaluated by neuropsychological tests (Six Elements Task-Adapted [SET-A], D-KEFS Sorting test and Stroop four-color version); generalization was measured by self-reporting questionnaires about daily functioning (Dysexecutive Functioning Questionnaire, forsaken daily activities). RESULTS ANCOVA results showed significant group-by-time interactions; the experimental group showed a statistically significant improvement on Tackling the 6 subtasks and Avoiding rule-breaking measures of the SET-A, with medium effect sizes. The generalization measure, the Dysexecutive Functioning Questionnaire, showed a significant reduction in experimental patient-significant other difference on the Executive cognition subscale. The number of forsaken daily activities was reduced in the experimental versus control group, which was not significant immediately after the CEP but was significant 6 months later. CONCLUSIONS Our study shows that older adults with TBI can improve their executive functioning, with a positive impact on everyday activities, after receiving multimodal cognitive training with the CEP.

[PMID: 34302502 DOI: 10.1007/s00068-021-01753-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Accepted: 07/18/2021] [Indexed: 11/30/2022]
Abstract
PURPOSE Most mild traumatic brain injuries (TBIs) can be treated conservatively. However, some patients deteriorate during observation. Therefore, we tried to evaluate the characteristics of deterioration and requirement for further management in mild TBI patients. METHODS From 1/1/2017 to 12/31/2017, patients with mild TBI and positive results on CT scans of the brain were retrospectively studied. Patients with and without neurological deteriorations were compared. The characteristics of mild TBI patients with further neurological deterioration or the requirement for interventions were delineated. RESULTS One hundred ninety-two patients were enrolled. Twenty-three (12.0%) had neurological deteriorations. The proportions of deterioration occurring within 24 h, 48 h and 72 h were 23.5, 41.2 and 58%, respectively. Deteriorated patients were significantly older than those without neurological deteriorations (69.7 vs. 60.2; p = 0.020). More associated extracranial injuries were observed in deteriorated patients [injury severity score (ISS): 20.2 vs. 15.9; p = 0.005). Significantly higher proportions of intraventricular hemorrhage (8.7 vs. 1.2%; p = 0.018) and multiple lesions (78.3 vs. 53.8%; p = 0.027) were observed on the CT scans of patients with neurological deteriorations. Subset analysis showed that deteriorated patients who required neurosurgical interventions (N = 7) had significantly more initial GCS defects (13 or 14) (71.4 vs. 12.5%; p = 0.005) and more initial decreased muscle power of extremities (85.7 vs. 18.8%; p = 0.002). CONCLUSION More attention should be given to mild TBI patients with older age, GCS defects, decreased muscle power of the extremities, multiple lesions on CT scans and other systemic injuries (high ISS). Most deteriorations occur within 72 h after trauma.

Abstract
BACKGROUND Despite a widely acknowledged increase in older people presenting with traumatic injury in western populations there remains a lack of research into the optimal prehospital management of this vulnerable patient group. Research into this cohort faces many uniqu1e challenges, such as inconsistent definitions, variable physiology, non-linear presentation and multi-morbidity. This scoping review sought to summarise the main challenges in providing prehospital care to older trauma patients to improve the care for this vulnerable group. METHODS AND FINDINGS A scoping review was performed searching Google Scholar, PubMed and Medline from 2000 until 2020 for literature in English addressing the management of older trauma patients in both the prehospital arena and Emergency Department. A thematic analysis and narrative synthesis was conducted on the included 131 studies. Age-threshold was confirmed by a descriptive analysis from all included studies. The majority of the studies assessed triage and found that recognition and undertriage presented a significant challenge, with adverse effects on mortality. We identified six key challenges in the prehospital field that were summarised in this review. CONCLUSIONS Trauma in older people is common and challenges prehospital care providers in numerous ways that are difficult to address. Undertriage and the potential for age bias remain prevalent. In this Scoping Review, we identified and discussed six major challenges that are unique to the prehospital environment. More high-quality evidence is needed to investigate this issue further.

Abstract
Objetivo Caracterizar os aspectos demográficos e sociais e o ônus econômico do traumatismo craniencefálico no sistema público de saúde brasileiro na última década. Métodos Analisaram-se os dados provenientes da base de dados do Departamento de Informática do Sistema Único de Saúde referentes ao período entre janeiro de 2008 e dezembro de 2019. Resultados Entre 2008 e 2019 ocorreram, em média, no Brasil, 131.014,83 internações por traumatismo craniencefálico ao ano, com incidência de 65,54 por 100 mil habitantes. Deve-se salientar a elevada incidência de traumatismo craniencefálico em adultos idosos (acima de 70 anos), acompanhada de altas taxas de mortalidade. Além disso, há também elevada incidência de traumatismo craniencefálico em adultos jovens (20 a 29 anos e 30 a 39 anos). Os dados aqui apresentados demonstram uma proporção de traumatismos craniencefálicos de 3,6 homens/mulheres. Conclusão Embora se acredite que os dados apresentados subestimem a incidência e mortalidade associadas com o traumatismo craniencefálico no Brasil, este estudo pode ajudar na implantação de futuras estratégias de promoção da saúde para a população brasileira e mundial, com o objetivo de diminuir a incidência, a mortalidade e os custos do traumatismo craniencefálico.

Abstract
BACKGROUND Acute subdural hematomas (aSDHs) occur in approximately 10% to 20% of all closed head injury and represent a significant cause of morbidity and mortality in traumatic brain injury patients. Conventional craniotomy is an invasive intervention with the potential for excess blood loss and prolonged postoperative recovery time. OBJECTIVE To evaluate the outcomes of minimally invasive endoscopy for evacuation of aSDHs in a pilot feasibility study. METHODS We retrospectively reviewed the records of consecutive patients with aSDHs who underwent surgical treatment at our institution with minimally invasive endoscopy using the Apollo/Artemis Neuro Evacuation Device (Penumbra, Alameda, California) between April 2015 and July 2018. RESULTS The study cohort comprised three patients. The Glasgow Coma Scale on admission was 15 for all 3 patients, median preoperative hematoma volume was 49.5 cm3 (range 44-67.8 cm3), median postoperative degree of hematoma evacuation was 88% (range 84%-89%), and median modified Rankin Scale at discharge was 1 (range 0-3). CONCLUSION Endoscopic evacuation of aSDHs can be a safe and effective alternative to craniotomy in appropriately selected patients. Further studies are needed to refine the selection criteria for endoscopic aSDH evacuation and evaluate its long-term outcomes.

Older Adults with Traumatic Brain Injury in the Most Aged and Most Rapidly Aging Country: An Analysis of the Nationwide Trauma Registry of Japan. World Neurosurg 2021; 150:e570-e576. [PMID: 33746100 DOI: 10.1016/j.wneu.2021.03.059] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2021] [Revised: 03/10/2021] [Accepted: 03/11/2021] [Indexed: 11/18/2022]
Abstract
BACKGROUND Despite the increasing numbers of older adults with traumatic brain injury (TBI), minimal data are available to support the development of treatment strategies. We aimed to comprehensively describe the incidence, characteristics, outcomes, and predictive accuracy of the severity indicators among older adults with TBI. METHODS Using the Japan Trauma Data Bank, we identified patients aged ≥18 years with TBI from 2004 to 2019. The patients were grouped according to age, and their baseline characteristics, radiological findings, severity, complications, and in-hospital mortality were assessed. Receiver operating characteristic curves were used to assess the accuracy of severity indicators for predicting in-hospital mortality. RESULTS Of the 94,180 patients who met the inclusion criteria, 50,990 (54.1%) were older adults (aged ≥65 years). Their proportion had increased at 2.1% annually, which exceeded the 0.5% annual increase in the general population. The proportion of women and the prevalence of comorbidities increased significantly with age. Traffic accidents were the leading cause of TBI among young adults, and falling at ground level was the leading cause for those aged ≥75 years. The radiological findings were significantly different among the age groups. The proportion of acute epidural hemorrhage, skull fracture, and diffuse axonal injury decreased and that of acute subdural hemorrhage increased with age. The predictive accuracy of the Glasgow coma scale, revised trauma score, and injury severity score decreased with increasing age. CONCLUSIONS The proportion of older patients with TBI increased more quickly than did the proportion of older people in the general population. The characteristics and predictive accuracy of the severity indicators differed significantly among the different age groups. TBI studies that focus on older patients are necessary.

Abstract
Purpose The world population is aging. As direct consequence, geriatric trauma is increasing both in absolute number and in the proportion of annual admissions causing a challenge for the health-care system worldwide. The aim of this review is to delineate the specific and practice rules for the management of mild brain trauma in the elderly. Methods Systematic review of the last 15 years literature on mild traumatic brain injury (nTBI) in elderly patients. Results A total of 68 articles met all eligibility criteria and were selected for the systematic review. We collected 29% high-quality studies and 71% low-quality studies. Conclusion Clinical advices for a comprehensive management are provided. Current outcome data from mTBIs in the elderly show a condition that cannot be sustained in the future by families, society, and health-care systems. There is a strong need for more research on geriatric mild brain trauma addressed to prevent falls, to reduce the impact of polypharmacy, and to define specific management strategies.

Abstract
Background The Glasgow Coma Scale (GCS) score has been adapted into categories of severity (mild, moderate, and severe) and are ubiquitous in the trauma setting. This study sought to revise the GCS categories to account for an interaction by age and to determine the discrimination of the revised categories compared with the standard GCS categories. Methods The American College of Surgeons National Trauma Data Bank registry was used to identify patients with traumatic brain injury (TBI; ICD-9 codes 850-854.19) who were admitted to participating trauma centers from 2010 to 2015. The primary exposure variables were GCS score and age, categorized by decade (teens, 20s, 30s…, 80s). In-hospital mortality was the primary outcome for examining TBI severity/prognostication. Logistic regression was used to calculate the conditional probability of death by age decade and GCS in a development dataset (75% of patients). These probabilities were used to create a points-based revision of the GCS, categorized as low (mild), moderate, and high (severe). Performance of the revised versus standard GCS categories was compared in the validation dataset using area under the receiver operating characteristic (AUC) curves. Results The final population included 539,032 patients with TBI. Age modified the performance of the GCS, resulting in a novel categorization schema for each age decile. For patients in their 50s, performance of the revised GCS categories mirrored the standard GCS categorization (3-8, 9-12, 13-15); all other revised GCS categories were heavily modified by age. Model validation demonstrated the revised GCS categories statistically significantly outperformed the standard GCS categories at predicting mortality (AUC: 0.800 vs 0.755, p<0.001). The revised GCS categorization also outperformed the standard GCS categories for mortality within pre-specified subpopulations: blunt mechanism, isolated TBI, falls, non-transferred patients. Discussion We propose the revised age-adjusted GCS categories will improve severity assessment and provide a more uniform early prognostic indicator of mortality following traumatic brain injury. Level of evidence III epidemiologic/prognostic.

Abstract
Objective With the aging of the global population, an increase in the proportion of elderly patients presenting with traumatic brain injury (TBI) is expected. This population presents several distinctive characteristics that impact management and outcome of TBI, such as comorbidities, frailty, and preinjury use of medications - specially antiplatelets and anticoagulants. The purpose of this study was to assess the general characteristics and prognostic factors of elderly patients with TBI that were surgically managed at a single institution. Methods The authors performed a retrospective review of all elderly patients (age ≥ 65 years) with a history of TBI that underwent cranial neurosurgical procedures at their institution, between 2015 and 2019. Clinical characteristics, laboratory tests, and radiological scans, as well as surgeries, performed, outcome, and prognostic factors were analyzed, comprising 133 consecutive cases overall. Results The mean age of patients was 76.6 ± 7.3 years, ranging from 65 years to 97 years. There was a predominance of males (71.4%) and the most frequent mechanism of injury was fall (80.4%). Mild TBI comprised 57.1% of the cases, followed by severe TBI in 25.6%. Frequent signs and symptoms were impaired consciousness (69.9%), focal motor deficits (32.3%), and gait disturbances (12.8%). The majority had reported comorbidities upon admission (79.7%), with cardiac disease (79.2%) and diabetes (24.5%) as the most frequent. Preinjury anticoagulation was reported in 18.8% and use of antiplatelet drugs in 17.3%. The most common finding in the head CT was chronic subdural hematoma (48.1%), followed by acute subdural hematoma (37.6%). Coagulation was found to be altered in 12.8% of the patients. The most common neurosurgical procedure performed was trephination for hematoma evacuation (56.3%), followed by craniotomy (21.2%). Blood product transfusion was needed in 61.7% of the patients. Overall mortality was 42.1%, with the majority in the first month after admission (83.9%). Unfavorable outcome (Glasgow Outcome Scale <5) at discharge was identified in 73% of the patients. Identified prognostic factors were TBI severity, absent pupillary reactivity, acute intracranial bleeding on head CT, basal cisterns obliteration, altered coagulation status, and need for blood transfusion. Conclusions TBI severity, pupillary reactivity, coagulation status, need for blood products transfusion and acute bleeding, as well as basal cisterns obliteration found in head CT, are factors that influenced the outcome in this series of elderly patients with TBI that need surgical management. It is paramount to observe the particularities of this population in this context, to optimize outcomes, avoid complications and ultimately generate awareness focused on prevention.

Abstract
Sports-related traumatic brain injury (TBI) is one of the common neurological maladies experienced by athletes. Earlier the term 'punch drunk syndrome' was used in the case TBI of boxers and now this term is replaced by chronic traumatic encephalopathy (CTE). Sports-related brain injury can either be short term or long term. A common instance of brain injury encompasses subdural hematoma, concussion, cognitive dysfunction, amnesia, headache, vision issue, axonopathy, or even death if remain undiagnosed or untreated. Further, chronic TBI may lead to pathogenesis of neuroinflammation and neurodegeneration via tauopathy, formation of neurofibrillary tangles, and damage to the blood-brain barrier, microglial, and astrocyte activation. Thus, altered pathological, neurochemical, and neurometabolic attributes lead to the modulation of multiple signaling pathways and cause neurological dysfunction. Available pharmaceutical interventions are based on one drug one target hypothesis and thereby unable to cover altered multiple signaling pathways. However, in recent time's pharmacological intervention of nutrients and nutraceuticals have been explored as they exert a multifactorial mode of action and maintain over homeostasis of the body. There are various reports available showing the positive therapeutic effect of nutraceuticals in sport-related brain injury. Therefore, in the current article we have discussed the pathology, neurological consequence, sequelae, and perpetuation of sports-related brain injury. Further, we have discussed various nutraceutical supplements as well as available animal models to explore the neuroprotective effect/ upshots of these nutraceuticals in sports-related brain injury.

Are There Any Red Flag Injuries in Severely Injured Patients in Older Age? J Clin Med 2021; 10:jcm10020185. [PMID: 33430174 PMCID: PMC7825590 DOI: 10.3390/jcm10020185] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2020] [Revised: 01/01/2021] [Accepted: 01/05/2021] [Indexed: 11/16/2022] Open
Abstract
Introduction: Severely injured elderly patients pose a significant burden to trauma centers and, compared with younger patients, have worse prognoses and higher mortality rates after major trauma. The objective of this study was to identify the etiological mechanisms that are associated with severe trauma in elderly patients and to detect which injuries correlate with high mortality in elderly patients. Methods: Using a prospect cohort study model over an 11-year period, severely injured patients (ISS ≥ 16) were divided into two age groups (Group 1: 18–64; Group 2: 65–99 years). A comparison of the groups was conducted regarding injury frequency, trauma mechanism, distribution of affected body parts (AIS and ISS regions) and injury related mortality. Results: In total, 1008 patient were included (Group 1: n = 771; Group 2: n = 237). The most relevant injury in elderly patients was falling from low heights (<3 m) in contrast to traffic accident in young patients. Severely injured patients in the older age group showed a significantly higher overall mortality rate compared to the younger group (37.6% vs. 11.7%; p = 0.000). In both groups, the 30-day survival for patients without head injuries was significantly better compared to patients with head injuries (92.7% vs. 85.3%; p = 0.017), especially analyzing elderly patients (86.6% vs. 58.6%; p = 0.003). The relative risk of 30-day mortality in patients who suffered a head injury was also higher in the elderly group (OR: Group 1: 4.905; Group 2: 7.132). Conclusion: In contrast to younger patients, falls from low heights (<3 m) are significant risk factors for severe injuries in the geriatric collective. Additionally, elderly patients with an ISS ≥ 16 had a significantly higher mortality rate compared to severe injured younger patients. Head injuries, even minor head traumata, are associated with a significant increase in mortality. These findings will contribute to the development of more age-related therapy strategies in severely injured patients.

[PMID: 33069218 PMCID: PMC7568018 DOI: 10.1186/s12883-020-01943-6] [Citation(s) in RCA: 29] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2020] [Accepted: 09/29/2020] [Indexed: 12/21/2022] Open
Abstract
Background Ageing is associated with worse treatment outcome after traumatic brain injury (TBI). This association may lead to a self-fulfilling prophecy that affects treatment efficacy. The aim of the current study was to evaluate the role of treatment bias in patient outcomes by studying the intensity of diagnostic procedures, treatment, and overall 30-day mortality in different age groups of patients with TBI. Methods Included in this study was consecutively admitted patients with TBI, aged ≥ 15 years, with a cerebral CT showing intracranial signs of trauma, during the time-period between 2015–2018. Data were extracted from our prospective quality control registry for admitted TBI patients. As a measure of management intensity in different age groups, we made a composite score, where placement of intracranial pressure monitor, ventilator treatment, and evacuation of intracranial mass lesion each gave one point. Uni- and multivariate survival analyses were performed using logistic multinomial regression. Results A total of 1,571 patients with TBI fulfilled the inclusion criteria. The median age was 58 years (range 15–98), 70% were men, and 39% were ≥ 65 years. Head injury severity was mild in 706 patients (45%), moderate in 437 (28%), and severe in 428 (27%). Increasing age was associated with less management intensity, as measured using the composite score, irrespective of head injury severity. Multivariate analyses showed that the following parameters had a significant association with an increased risk of death within 30 days of trauma: increasing age, severe comorbidities, severe TBI, Rotterdam CT-score ≥ 3, and low management intensity. Conclusion The present study indicates that the management intensity of hospitalised patients with TBI decreased with advanced age and that low management intensity was associated with an increased risk of 30-day mortality. This suggests that the high mortality among elderly TBI patients may have an element of treatment bias and could in the future be limited with a more aggressive management regime.

Clinical characteristics and outcomes in patients with traumatic brain injury in China: a prospective, multicentre, longitudinal, observational study. Lancet Neurol 2020; 19:670-677. [PMID: 32702336 DOI: 10.1016/s1474-4422(20)30182-4] [Citation(s) in RCA: 74] [Impact Index Per Article: 18.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2019] [Revised: 05/02/2020] [Accepted: 05/04/2020] [Indexed: 12/27/2022]
Abstract
BACKGROUND Large-scale studies are required to better characterise traumatic brain injury (TBI) and to identify the most effective treatment approaches for TBI. However, evidence is scarce and mostly originates from high-income countries. We aimed to describe the existing care for patients with TBI and the outcomes in China. METHODS The Collaborative European NeuroTrauma Effectiveness Research in TBI (CENTER-TBI) China registry is a prospective, multicentre, longitudinal, observational study done in 56 neurosurgical centres across China. We collected data of patients who were admitted to hospital with a clinical diagnosis of TBI and an indication for CT. Patients who were discharged directly from the emergency room were excluded. The primary endpoint was survival on discharge. Prognostic analyses were applied to identify predictors of mortality. Variations in mortality were compared between centres and provinces within China. Mortality was compared with expected mortality, estimated using the CRASH basic model. This study was registered with ClinicalTrials.gov, NCT02210221. FINDINGS From Dec 22, 2014, to Aug 1, 2017, 13 627 patients with TBI from 56 centres were enrolled in the registry. Data from 13 138 patients from 52 hospitals in 22 provinces of China were analysed. Most patients were male (9782 [74%]), with a median age of 48 years (IQR 33-61). The median Glasgow Coma Scale (GCS) score was 13 (IQR 9-15), and the leading cause of injury was road-traffic incident (6548 [50%]). Overall, 637 (5%) patients died, including 552 (20%) patients with severe TBI. Age, GCS score, injury severity score, pupillary light reflex, CT findings (compressed basal cistern and midline shift ≥5 mm), presence of hypoxia, systemic hypotension, altitude higher than >500 m, and GDP per capita were significantly associated with survival in all patients with TBI. Variation in mortality existed between centres and regions. The expected 14-day mortality was 1116 (13%), but 544 (7%) deaths within 14 days were observed (observed to expected ratio 0·49 [95% CI 0·45-0·53]). INTERPRETATION The results show differences in mortality between centres and regions across China, which indicates potential for identifying best practices through comparative effectiveness research. The risk factors identified in prognostic analyses might contribute to developing benchmarks for assessing quality of care. FUNDING None.

Abstract
PROBLEM Falls are the leading cause of injury deaths among adults aged 65 years and older. Characteristics of these falls may vary with alcohol use. OBJECTIVE Describe and compare characteristics of older adult fall-related emergency department (ED) visits with indication of alcohol to visits with no indication. METHODS Using nationally-representative 2015 National Electronic Injury Surveillance System-All Injury Program data, we compared demographic characteristics for fall-related ED visits by indication of alcohol consumption. Alcohol-indicated ED visits were matched on age group, sex, treatment month, and treatment day to ED visits with no alcohol indication using a 1:4 ratio and injury characteristics (i.e., diagnosis, body part injured, disposition) were compared. RESULTS AND DISCUSSION Of 38,640 ED records, 906 (1.9%) indicated use of alcohol. Fall-related ED visits among women were less likely to indicate alcohol (1.0%) compared to ED visits among men (3.8%). ED visits indicating alcohol decreased with age from 4.1% for those 65-74 years to 1.5% for those 75-84 and <1% for those 85+. After controlling for age-group, sex, and month and day of treatment, 17.0% of ED visits with no alcohol indication had a traumatic brain injury compared to 34.8% of alcohol-indicated ED visits. Practical applications: Alcohol-indicated fall ED visits resulted in more severe head injury than those that did not indicate alcohol. To determine whether alcohol use should be part of clinical risk assessment for older adult falls, more routinely collected data and detailed information on the amount of alcohol consumed at the time of the fall are needed.

The effect of milrinone on mortality in adult patients who underwent CABG surgery: a systematic review of randomized clinical trials with a meta-analysis and trial sequential analysis. BMC Cardiovasc Disord 2020; 20:328. [PMID: 32640988 PMCID: PMC7346403 DOI: 10.1186/s12872-020-01598-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2019] [Accepted: 06/25/2020] [Indexed: 12/12/2022] Open
Abstract
Background As an inodilator, milrinone is commonly used for patients who undergo coronary artery bypass graft (CABG) surgery because of its effectiveness in decreasing the cardiac index and mitral regurgitation. The aim of this study was to perform a systematic review and meta-analysis of existing studies from the past 20 years to evaluate the impact of milrinone on mortality in patients who undergo CABG surgery. Methods We performed a systematic literature search on the application of milrinone in patients who underwent CABG surgery in studies published between 1997 and 2017 in BioMed Central, PubMed, EMBASE, and the Cochrane Central Register. The included studies evaluated milrinone groups compared to groups receiving either placebo or standard treatment and further compared the systemic administration. Results The network meta-analysis included 723 patients from 16 randomized clinical trials. Overall, there was no significant difference in mortality between the milrinone group and the placebo/standard care group when patients underwent CABG surgery. In addition, 9 trials (with 440 randomized patients), 4 trials (with 212 randomized patients), and 10 trials (with 470 randomized patients) reported that the occurrence of myocardial infarction (MI), myocardial ischemia, and arrhythmia was lower in the milrinone group than in the placebo/standard care group. Between the milrinone treatment and placebo/standard care groups, the occurrence of myocardial infarction, myocardial ischemia, and arrhythmia was significantly different. However, the occurrence of stroke and renal failure, the duration of inotropic support (h), the need for an intra-aortic balloon pump (IABP), and mechanical ventilation (h) between these two groups showed no differences. Conclusions Based on the current results, compared with placebo, milrinone might be unable to decrease mortality in adult CABG surgical patients but can significantly ameliorate the occurrence of MI, myocardial ischemia, and arrhythmia. These results provide evidence for the further clinical application of milrinone and of therapeutic strategies for CABG surgery. However, along with milrinone application in clinical use, sufficient data from randomized clinical trials need to be collected, and the potential benefits and adverse effects should be analyzed and reevaluated.

Abstract
Traumatic brain injury (TBI) causes substantial mortality and long-term disability worldwide. TGFβ1 is a unique molecular and functional signature in microglia, but the role of TGFβ1 in TBI is not clear. The purpose of this study was to investigate the role of TGFβ1 in TBI. The weight dropping device was used to establish TBI model of rats. Hematoxylin eosin staining and Bielschowsky silver staining were used to assess tissue loss. Beam walking and muscle strength tests were used to assess neurological deficits. Immunohistochemical staining was used to assess axonal injures. Western blotting was used to detect expression of related proteins. RT-PCR was used to detect expression of cytokines. Immunofluorescence staining was used to assess the microglia/macrophages activation. We observed obvious axonal injury and microglia/macrophages activation in the peri-lesion cortex. The expression of inflammatory cytokines was markedly high after TBI. The expression of TGFβ1 and TGFβRI were significantly reduced after TBI. TGFβ1 promoted the functional recovery and alleviated axonal injury 1 day after TBI. TGFβ1 promoted microglia/macrophages polarizing to alternative activation and alleviated neuroinflammation. These effects of TGFβ1 could be inhibited by LY2109761, the inhibitor of TGFRI/II. These results suggested that TGFβ1 played a protective role in axonal injury and could be a potential therapeutic target in early stages following TBI.

Abstract
BACKGROUND There is considerable evidence that prolonged use of cervical collars potentially cause detrimental effects including increase in optic nerve sheath diameter (ONSD) among healthy volunteers. Different types of cervical collars immobilize cervical spine variably well and may presumably differently influence the venous compression and hence the intracranial pressure. We therefore aimed to evaluate the influence of cervical spine immobilization with 5 different types of cervical collars on ONSD measured noninvasively by ultrasound on healthy volunteers. METHODS We conducted a randomized crossover trial including 60 adult healthy volunteers. Control assessment of the optic nerve sheath thickness was performed in both sagittal and transverse planes. Patient was placed supine on a transport stretcher, cervical collar was placed, and ONSD measurement was performed after 5 and 20 minutes. During the next days, the procedure was repeated with random allocation of participants and random cervical collar. RESULTS Sixty healthy volunteers were included in our study. ONSD left diameter [mm] for the baseline was 3.8 [interquartile range (IQR): 3.65-3.93)] mm. Using AMBU after 5 min, ONSD was changed up to 4.505 (IQR 4.285-4.61; P < .001) mm. The largest change at 5 minutes and 20 minutes was using Philly 4.73 (IQR: 4.49-4.895; P < .001) and 4.925 (IQR: 4.65-5.06; P < .001), respectively. Necklite reported the lower change in ONSD: 3.92 (IQR: 3.795-4; P = 1.0) mm in 5 minutes and 3.995 (IQR: 3.875 - 4.1; P = 1.0) mm in 20 minutes. ONSD right diameter [mm] for the baseline was 3.8 (IQR 3.675-3.9) mm. Using AMBU after 5 minutes, ONSD was changed up to 4.5 (IQR 4.21-4.6) mm. The largest change at 5 minutes and 20 minutes was using Philly 4.705 (IQR 4.455-4.9) and 4.93 (IQR 4.645-5.075), respectively. Necklite reported the lower change in ONSD -33.9 (IQR 3.795-3.99) mm in 5 minutes and 3.995 (IQR 3.86-4.09) mm in 20 minutes. CONCLUSION We report significant increase of ONSD from the baseline after cervical collar placement among healthy volunteers at 5 minutes and 20 minutes interval. In addition, no significant difference was noted between ONSD measurements at 5 and 20 minutes. Clinicians should take proactive steps to assess the actual need of cervical collar case by case basis. Nonetheless, when needed, Necklite moldable neck brace seems to be a reasonable option.Registration: ClinicalTrials database (www.clinicaltrials.gov, NCT03609879).

Abstract
BACKGROUND We sought to evaluate the role of trauma center designation in the association of race and insurance status with disposition to rehabilitation centers among elderly patients with Traumatic Brain Injury (TBI). METHODS The National Trauma Data Bank (2014-2015) was used to identify elderly (age ≥ 65) patients with isolated moderate to severe blunt TBI who survived to discharge. Race, insurance status, and outcomes were stratified by trauma center designation and compared. RESULTS 3,292 patients met the inclusion criteria. Black patients were 1.5 times less likely (AOR 0.64, p = 0.01) and Latino patients were 1.7 times less likely (AOR 0.58, p = 0 0.007) to be discharged to rehabilitation centers as compared with White patients. Asian patients at Level I hospitals were more likely to be discharged to rehabilitation centers if they had private vs. non-private insurance (42.9% versus 12.7%, p = 0.01). CONCLUSION Black and Latino patients were less likely to be discharged to rehabilitation centers compared to White patients. The etiology of these disparities deserves further study.

Abstract
As part of a verification model of antibiotic therapy in cranioplasty, we evaluated the impregnation efficiency of interporous calcium phosphate materials with saline under atmospheric pressure and compared it to the efficiency of using the decompression method established by the Japanese Industrial Standard, under which pressure is reduced by 10 kPa. Five types of material formed in 1 mL cubes were selected as test samples: two consisting of hydroxyapatite (HAp) with 85% and 55% porosity and three of β-tricalcium phosphate (β-TCP) with 75%, 67%, and 57% porosity. All test samples showed an impregnation ratio of more than 70%, except for the HAp sample with 55% porosity, which had a ratio of approximately 50%. These high ratios were achieved at only 15 min. The impregnation effects were likely dependent on porosity and were independent of base material, either HAp or β-TCP. Obtaining sufficient impregnation and antimicrobial efficacy in materials with low porosity, which are commonly used in cranioplasty, would require an increased volume of antibiotics rather than increased duration of impregnation. Our findings will enable the simple preparation of drug-impregnated calcium phosphate materials, even in operating rooms not equipped with a large decompression device.
