Traumatic brain injury research: a review of clinical studies

The Effectiveness of Brain Injury Family Intervention in Improving the Psychological Well-Being of Caregivers of Patients With Traumatic Brain Injury: Protocol for a Randomized Controlled Trial

BACKGROUND

Globally, traumatic brain injury (TBI) is recognized as one of the most significant contributors to mortality and disability. Most of the patients who have experienced TBI will be discharged home and reunited with their families or primary caregivers. The degree of severity of their reliance on caregivers varies. Therefore, the task of delivering essential care to the patients becomes demanding for the caregivers. A significant proportion of caregivers expressed considerable burden, distress, and discontentment with their lives. Therefore, it is critical to comprehend the dynamic of TBI and caregivers to optimize patient care, rehabilitation, and administration. The effectiveness of the Brain Injury Family Intervention (BIFI) program tailored for caregivers of patients with TBI has been widely proven in Western countries. However, the impact is less clear among caregivers of patients with TBI in Malaysia.

OBJECTIVE

This study aims to assess the effectiveness of BIFI in reducing emotional distress and burden of care, fulfilling the needs, and increasing the life satisfaction of caregivers of patients with TBI at government hospitals in Malaysia.

METHODS

This is a 2-arm, single-blinded, randomized controlled trial. It will be conducted at Hospital Rehabilitasi Cheras and Hospital Sungai Buloh. In total, 100 caregivers of patients with TBI attending the neurorehabilitation unit will be randomized equally to the intervention and control groups. The intervention group will undergo the BIFI program, whereas the control group will receive standard treatment. Caregivers aged ≥18 years, caring for patients who have completed >3 months after the injury, are eligible to participate. The BIFI program will be scheduled for 5 sessions as recommended by the developer of the module. Each session will take approximately 90 to 120 minutes. The participants are required to attend all 5 sessions. A total of 5 weeks is needed for each group to complete the program. Self-reported questionnaires (ie, Beck Depression Inventory, Positive and Negative Affect Schedule, Caregiver Strain Index, Satisfaction With Life Scale, and Family Needs Questionnaire) will be collected at baseline, immediately after the intervention program, at 3-month follow-up, and at 6-month follow-up. The primary end point is the caregivers' emotional distress.

RESULTS

The participant recruitment process began in January 2019 and was completed in December 2020. In total, 100 participants were enrolled in this study, of whom 70 (70%) caregivers are women and 30 (30%) are men. We are currently at the final stage of data analysis. The results of this study are expected to be published in 2024. Ethics approval has been obtained.

CONCLUSIONS

It is expected that the psychological well-being of the intervention group will be better compared with that of the control group after the intervention at 3-month follow-up and at 6-month follow-up.

Astrocytes Mediate Protective Actions of Estrogenic Compounds after Traumatic Brain Injury

Traumatic brain injury (TBI) is a serious public health problem. It may result in severe neurological disabilities and in a variety of cellular metabolic alterations for which available therapeutic strategies are limited. In the last decade, the use of estrogenic compounds, which activate protective mechanisms in astrocytes, has been explored as a potential experimental therapeutic approach. Previous works have suggested estradiol (E2) as a neuroprotective hormone that acts in the brain by binding to estrogen receptors (ERs). Several steroidal and nonsteroidal estrogenic compounds can imitate the effects of estradiol on ERs. These include hormonal estrogens, phytoestrogens and synthetic estrogens, such as selective ER modulators or tibolone. Current evidence of the role of astrocytes in mediating protective actions of estrogenic compounds after TBI is reviewed in this paper. We conclude that the use of estrogenic compounds to modulate astrocytic properties is a promising therapeutic approach for the treatment of TBI.

The Distribution of Transplanted Umbilical Cord Mesenchymal Stem Cells in Large Blood Vessel of Experimental Design With Traumatic Brain Injury

The authors aim to track the distribution of human umbilical cord mesenchymal stem cells (MSCs) in large blood vessel of traumatic brain injury -rats through immunohistochemical method and small animal imaging system. After green fluorescent protein (GFP) gene was transfected into 293T cell, virus was packaged and MSCs were transfected. Mesenchymal stem cells containing GFP were transplanted into brain ventricle of rats when the infection rate reaches 95%. The immunohistochemical and small animal imaging system was used to detect the distribution of MSCs in large blood vessels of rats. Mesenchymal stem cells could be observed in large vessels with positive GFP expression 10 days after transplantation, while control groups (normal group and traumatic brain injury group) have negative GFP expression. The vascular endothelial growth factor in transplantation group was higher than that in control groups. The in vivo imaging showed obvious distribution of MSCs in the blood vessels of rats, while no MSCs could be seen in control groups. The intravascular migration and homing of MSCs could be seen in rats received MSCs transplantation, and new angiogenesis could be seen in MSCs-transplanted blood vessels.

Functioning and disability in traumatic brain injury: the Italian patient perspective in developing ICF Core Sets

OBJECTIVE

The purpose of the study was to explore the aspects of functioning and health relevant to patients with traumatic brain injury (TBI) and to the caregivers of TBI patients explicitly involved in the preliminary study for the Development of the ICF Core Set for TBI using a qualitative research method.

METHOD

The sampling of patients followed the maximum variation strategy. To respect this strategy, we involved patients with different degrees of impairment and so, for some people it was not possible to join the group because of their severe cognitive impairment, in this case we interviewed their caregivers. The focus groups were digitally recorded and transcribed verbatim. The meaning condensation procedure was used for the data analysis. After qualitative data analyses, the resulting concepts were linked to ICF categories according to established linking rules.

RESULTS

Eighteen focus groups and five single interviews were performed. Forty-one patients participated in 10 focus groups. Thirty-three caregivers participated in eight focus group and six caregivers underwent a single interview. Saturation at 10% cutoff was reached. Based on 10 patient focus groups, we linked the concepts to 144 2nd level ICF different categories. In the eight focus group with caregiver we linked the concepts to 129 2nd level categories. In the single interviews, we could link the concepts only to Environmental factors and we linked to 25 ICF different categories.

CONCLUSION

A broad range of aspects of functioning and health as well as several Environmental factors important to patients with TBI were explored and included in the preparatory phase of the development of ICF Core Sets for TBI. Whereas patients focused on problems in mobility, employment and recreation and leisure the caregivers highlighted several issues related to self-care as being important for the patients.

Les perceptions d’adolescents cérébrolésés, de leurs parents et des professionnels impliqués dans leur inclusion sociale

Cette étude qualitative a pour but d'explorer les perceptions d’adolescents, de leurs parents et de professionnelles quant à l'inclusion sociale d’adolescents ayant vécu un traumatisme craniocérébral (TCC) modéré. Le modèle écologique de Bronfenbrenner (1979, 1986), adapté par Lefebvre et Levert (2005) auprès de la clientèle TCC, est utilisé comme cadre de référence. Des entrevues semi-dirigées ont été réalisées auprès d’adolescents cérébrolésés et leurs parents. Les résultats montrent que les perceptions des familles portent sur différents aspects de leur vie, indiquant une multitude de répercussions qui facilitent ou contraignent l’inclusion sociale de l’adolescent TCC modéré. En général, les professionnelles partagent les mêmes perceptions qu’eux. Les résultats de cette étude devraient permettre aux professionnels de la santé une meilleure compréhension de l'inclusion sociale vécue par ces personnes, en plus d'offrir des balises permettant à ceux-ci de mieux soutenir l'inclusion sociale d’adolescents TCC et de venir en aide aux familles dans cette situation difficile.

Urban-rural differences in pediatric traumatic head injuries: A prospective nationwide study

AIMS

To estimate differences in the incidence of recorded traumatic head injuries by gender, age, severity, and geographical area.

METHODS

The study was prospective and nationwide. Data were collected from all hospitals, emergency units and healthcare centers in Iceland regarding all Icelandic children and adolescents 0-19 years old consecutively diagnosed with traumatic head injuries (N = 550) during a one-year period.

RESULTS

Annual incidence of minimal, mild, moderate/severe, and fatal head injuries (ICD-9 850-854) was 6.41 per 1000, with 95% confidence interval (CI) 5.9, 7.0. Annual incidence of minimal head injuries (ICD-9 850) treated at emergency units was 4.65 (CI 4.2, 5.1) per 1000, mild head injuries admitted to hospital (ICD-9 850) was 1.50 (CI 1.3, 1.8) per 1000, and moderate/severe nonfatal injuries (ICD-9 851-854) was 0.21 (CI 0.1, 0.3) per 1000. Death rate was 0.05 (CI 0.0, 0.1) per 1000. Young children were at greater risk of sustaining minimal head injuries than older ones. Boys were at greater risk than girls were. In rural areas, incidence of recorded minimal head injuries was low.

CONCLUSIONS

Use of nationwide estimate of the incidence of pediatric head injury shows important differences between urban and rural areas as well as between different age groups.

Living with moderate or severe traumatic brain injury: the meaning of family members' experiences

Traumatic brain injury (TBI) has long-lasting consequences not only for the individual with the injury but also for family members. The aim of this study is to elucidate the meaning of family members' experiences of living with an individual with moderate or severe TBI. The data have been collected by means of qualitative research interviews with 8 family member participants. A phenomenological hermeneutic interpretation (Ricouer, 1976) of the data reveal that family members struggle with their own suffering while showing compassion for the injured person. Their willingness to assume care for the injured person is derived from their feeling of natural love and the ethical demand to be responsible for the other. Hope and natural love from close relatives, the afflicted person, and other family members give the family members strength. It is important that professionals pay more attention to the suffering of close relatives.

Interdisciplinary Family Intervention Program

Throughout the delivery of care after traumatic brain injury, the type of relationship that develops between the family and the professionals has a major effect on the day-by-day adjustment of traumatic brain injury individuals and their relatives. Seventeen health professionals from different disciplines working with the traumatic brain injury clientele at different stages of the continuum of trauma care underwent training in the form of e-learning to apply the Interdisciplinary Family Intervention Program, or PRIFAM. The study methodology was mixed: participants' evaluation of the PRIFAM training was assessed through a quantitative questionnaire, whereas their experience and learning were documented in semiguided, qualitative interviews conducted before and after training. The results show that the training stimulated personal and professional reflective thought in participants and fostered the forging of an interdisciplinary partnership. The training had a positive impact on communication between professionals and with the families and helped to develop a sense of self-efficacy among health professionals.
