Relevance. The problem of effective prevention and treatment of traumatic brain injuries (TBI) of various etiologies has not been resolved in all countries of the world. Primary brain damage from trauma initiates secondary damage to the nervous tissue. As a result, the interaction of brain neural networks is disrupted and the control of somatic and visceral functions of the body is weakened. The article is based on our own clinical observations and comparison of results with literature data and provides a discussion of the prospects for the use of cell technologies in the prevention of fatal disorders of vital functions control in traumatic brain injuries. Objective. To evaluate the effectiveness of intranasal perineural implantation of mesenchymal stem cells (MSCs) in the complex therapy of patients with TBI. Materials and methods. The technique intranasal perineural administration of MSCs was used in complex therapy of 15 patients with severe TBI. The patients were 19÷69 years old, 13 men and two women. A cell suspension was isolated from the adipose tissue of the patient's abdominal wall and centrifuged for 10 min at 1500 rpm. The cell pellet was washed in phosphate buffered saline and DMEM. Cells were cultured in plastic culture flasks in a humidified atmosphere with 5% CO2 content. The cell mass was trypsinized according to standard technique and resuspended in physiological saline on the day of implantation. Dynamics of culture growth, pluripotency, phenotyping of MSCs were monitored. MSCs were injected under general anesthesia into the submucosa of the nasal cavity 3-4 times with an interval of 3-7 days, depending on the growth rate of MSCs, in a single dose from 12.0×106 to 35.0×106 cells. Results. The use of allogeneic and predominantly autologous MSCs of adipose tissue in the complex treatment of patients with severe TBI by intranasal perineural delivery to the area of traumatic brain injury does not cause complications and is a safe technique. 8 patients with severe TBI showed from 4 to 7 points according to the Glasgow Outcome Scale Extended, with an average of 5.4±1.1 points after 6 months. The main result is that complex therapy, including intranasal implantation of MSCs in acute and subacute periods of severe TBI, contributes to the survival of patients and restoration of neurological – including cognitive – functions control. Conclusions. The effectiveness of intranasal perineural implantation of MSCs in the complex therapy of patients with TBI has been demonstrated. The mechanisms of the beneficial effects of perineural implantation of MSCs in patients with TBI require further research.

Abstract Objective This study aimed at determining the prevalence of traumatic brain injuries (TBI) among guests staying at a low-barrier homeless shelter who represent an especially vulnerable subset of individuals experiencing homelessness. Results A total of 21 out of 35 shelter guests participated in the survey. We found that 17 (81.0%) had experienced at least one traumatic brain injury in their lifetime and 15 (71.3%) had TBI associated with loss of consciousness. In addition, 7 (33.3%) of the participants had experienced TBIs rated as moderate to severe. Of the participants with head trauma history, 16 (94.1%) experienced their injury before their first onset of homelessness. Compared to both the general population and the broader population of individuals experiencing homelessness, those in this sample were significantly more likely to experience TBI (95% CI 0.0000:0.2857; p < 0.001 and 95% CI 0.3333:0.7619; p < 0.015, respectively) and significantly more likely to experience severe TBI (95% CI 0.0000:0.09524; p < 0.001).

Experimental Traumatic Brain Injury

Traumatic brain injury is one of the leading causes of mortality and morbidity worldwide. At present there is no effective treatment. Previous studies have demonstrated that topical application of adipose tissue-derived mesenchymal stem cells can improve functional recovery in experimental traumatic brain injury. In this study, we evaluated whether hypoxic preconditioned mesenchymal stem cells could enhance the recovery from traumatic brain injury. Traumatic brain injury was induced with an electromagnetically controlled cortical impact device. Two million mesenchymal stem cells derived from the adipose tissue of transgenic green fluorescent protein Sprague-Dawley rats were cultured under either hypoxic (2.5% O2 for 18 hours) ( N = 30) or normoxic (18% O2) ( N = 30) conditions, then topically applied to the exposed cerebral cortex within 1 hour after traumatic brain injury. A thin layer of fibrin was used to fix the cells in position. No treatment was given to the animals with traumatic brain injury ( N = 30). Animals that underwent craniectomy without traumatic brain injury were treated as the sham group ( N = 15). Neurological functions were evaluated with water maze, Roto-rod and gait analysis. Animals were sacrificed at days 3, 7, and 14 for microscopic examinations and real-time polymerase chain reaction analysis. The rats treated with hypoxic mesenchymal stem cells showed the greatest improvement in neurological function recovery. More green fluorescent protein-positive cells were found in the injured brain parenchyma treated with hypoxic mesenchymal stem cells that co-expressed glial fibrillary acidic protein, Nestin, and NeuN. Moreover, there was early astrocytosis triggered by the infiltration of more glial fibrillary acidic protein-positive cells and microgliosis was suppressed with fewer ionized calcium binding adapter molecule 1-positive cells in the penumbra region of hypoxic mesenchymal stem cells group at day 3. Compared with normoxic mesenchymal stem cells and traumatic brain injury only groups, there was significantly ( p < 0.05) less neuronal death in both the hippocampus and penumbral regions in sections treated with hypoxic mesenchymal stem cells as determined by Cresyl violet and terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling staining respectively. The expression of pro-inflammatory genes (interleukin 6, interleukin 1a, interleukin 1b, tumor necrosis factor α) was upregulated and apoptotic gene (Caspase-3) expression was suppressed at day 3. Anti-inflammatory (interleukin 10) and anti-apoptotic (BCL2 associated agonist of cell death) gene expression was upregulated at days 7 and 14. Our study showed that a hypoxic precondition enhanced the beneficial effects of mesenchymal stem cells on neurological recovery after traumatic brain injury.

Objective: Traumatic brain injury (TBI) is increasingly recognized as a common and impactful health determinant in homeless and precariously housed populations. We sought to describe the history of TBI in a precariously housed sample and evaluate how TBI was associated with the initial loss and lifetime duration of homelessness and precarious housing. Method: We characterized the prevalence, mechanisms, and sex difference of lifetime TBI in a precariously housed sample. We also examined the impact of TBI severity and timing on becoming and staying homeless or precariously housed; 285 precariously housed participants completed the Brain Injury Screening Questionnaire in addition to other health assessments. Results: A history of TBI was reported in 82.1% of the sample, with 64.6% reporting > 1 TBI, and 21.4% reporting a moderate or severe TBI. Assault was the most common mechanism of injury overall, and females reported significantly more traumatic brain injuries due to physical abuse than males (adjusted OR = 1.26, 95% CI = 1.14 to 1.39, P < 0.0001). The first moderate or severe TBI was significantly closer to the first experience of homelessness ( b = 2.79, P = 0.003) and precarious housing ( b = 2.69, P < 0.0001) than was the first mild TBI. In participants who received their first TBI prior to becoming homeless or precariously housed, traumatic brain injuries more proximal to the initial loss of stable housing were associated with a longer lifetime duration of homelessness (RR = 1.04, 95% CI = 1.02 to 1.06, P < 0.0001) and precarious housing (RR = 1.03, 95% CI = 1.01 to 1.04, P < 0.0001). Conclusions: These findings demonstrate the high prevalence of TBI in this vulnerable population, and that aspects of TBI severity and timing are associated with the loss and lifetime duration of stable housing.

Intracranial Hematomas

Multiple traumatic hematomas (MG) account for 0.74% of all traumatic brain injuries. A comprehensive diagnostic approach to multiple traumatic intracranial hematomas allows to establish a diagnosis in the early stages of traumatic brain injury and to determine treatment tactics. A differentiated approach to the choice of surgical treatment of multiple hematomas allows to achieve satisfactory results and treatment outcomes, which accordingly contributes to the early activation of the patient, a reduction in hospital stay, a decrease in mortality and disabilityin patients with traumatic brain injury

Effect Sizes

Hyperbaric oxygen therapy has been proposed as a method to treat traumatic brain injuries. The combination of pressure and increased oxygen concentration produces a higher content of dissolved oxygen in the bloodstream, which could generate a therapeutic benefit for brain injuries. This dissolved oxygen penetrates deeper into damaged brain tissue than otherwise possible and promotes healing. The result includes improved cognitive functioning and an alleviation of symptoms. However, randomized controlled trials have failed to produce consistent conclusions across multiple studies. There are numerous explanations that might account for the mixed evidence, although one possibility is that prior evidence focuses primarily on statistical significance. The current analyses explored existing evidence by calculating an effect size from each active treatment group and each control group among previous studies. An effect size measure offers several advantages when comparing across studies as it can be used to directly contrast evidence from different scales, and it provides a proximal measure of clinical significance. When exploring the therapeutic benefit through effect sizes, there was a robust and consistent benefit to individuals who underwent hyperbaric oxygen therapy. Placebo effects from the control condition could account for approximately one-third of the observed benefits, but there appeared to be a clinically significant benefit to using hyperbaric oxygen therapy as a treatment intervention for traumatic brain injuries. This evidence highlights the need for design improvements when exploring interventions for traumatic brain injury as well as the importance of focusing on clinical significance in addition to statistical significance.
