Next-generation personalized cranioplasty treatment

Decompressive craniectomy (DC) is a surgical procedure, that is followed by cranioplasty surgery. DC is usually performed to treat patients with traumatic brain injury, intracranial hemorrhage, cerebral infarction, brain edema, skull fractures, etc. In many published clinical case studies and systematic reviews, cranioplasty surgery is reported to restore cranial symmetry with good cosmetic outcomes and neurophysiologically relevant functional outcomes in hundreds of patients. In this review article, we present a number of key issues related to the manufacturing of patient-specific implants, clinical complications, cosmetic outcomes, and newer alternative therapies. While discussing alternative therapeutic treatments for cranioplasty, biomolecules and cellular-based approaches have been emphasized. The current clinical practices in the restoration of cranial defects involve 3D printing to produce patient-specific prefabricated cranial implants, that provide better cosmetic outcomes. Regardless of the advancements in image processing and 3D printing, the complete clinical procedure is time-consuming and requires significant costs. To reduce manual intervention and to address unmet clinical demands, it has been highlighted that automated implant fabrication by data-driven methods can accelerate the design and manufacturing of patient-specific cranial implants. The data-driven approaches, encompassing artificial intelligence (machine learning/deep learning) and E-platforms, such as publicly accessible clinical databases will lead to the development of the next generation of patient-specific cranial implants, which can provide predictable clinical outcomes. STATEMENT OF SIGNIFICANCE: Cranioplasty is performed to reconstruct cranial defects of patients who have undergone decompressive craniectomy. Cranioplasty surgery improves the aesthetic and functional outcomes of those patients. To meet the clinical demands of cranioplasty surgery, accelerated designing and manufacturing of 3D cranial implants are required. This review provides an overview of biomaterial implants and bone flap manufacturing methods for cranioplasty surgery. In addition, tissue engineering and regenerative medicine-based approaches to reduce clinical complications are also highlighted. The potential use of data-driven computer applications and data-driven artificial intelligence-based approaches are emphasized to accelerate the clinical protocols of cranioplasty treatment with less manual intervention and shorter intraoperative time.

Neurological rehabilitation following heat illness in the UK Armed Forces

Heat illness remains a significant threat to health in the UK Armed Forces despite recent improvements in the prevention of cases. A small number of heat illness survivors develop long-term neurological sequelae. Here we briefly review the background literature and present our experience of treating UK Armed Forces patients with neurological consequences of heat illness. In our cohort of patients, we observed significant improvements in subjective symptoms and objective assessments following a period of neurological rehabilitation at the Defence Medical Rehabilitation Centre. We conclude with recommendations for further research and for the incorporation of screening for neurological disability following heat illness into service policy.

Time between acquired brain injury and admission to community-based rehabilitation: differences in cognitive and functional gains

OBJECTIVE

To determine differences in rehabilitation gains made by people with an acquired brain injury undergoing staged community-based brain injury rehabilitation (SCBIR) at different times between injury and admission.

METHOD

Retrospective cohort analysis of routinely collected demographic and rehabilitation data from clients admitted to SCBIR service 2011-2017 (n=92). Outcome measures: Mayo-Portland Adaptability Inventory-4 (MPAI-4) and UK Functional Assessment Measure (UK FIM+FAM) collected on admission and annually thereafter until discharge. Analysis was stratified by time since injury on admission: 'Early' (<1 year (n=36)), 'Middle' (1-2 years (n=34)) and 'Late' (>2 years (n=22)). Between-group differences were tested using bootstrapped one-way ANOVA. Within-group differences were tested using paired T tests.

RESULTS

Total cohort made significant gains in MPAI-4 and UK FIM+FAM total and all subscales (p = .001). Early group made greatest change in all subscales of both outcome measures (p < .01). Middle cohort improved significantly in all subscales (p < .02) excluding MPAI-4 Adjustment. Late cohort still made statistically significant gains in all UK FIM+FAM subscales (p < .05) and MPAI-4 Participation (p < .01). Item level changes are presented.

CONCLUSION

More than 2 years after injury, people are able to make improvements in participation and functional independence following SCBIR.
