Biomimetic ECM nerve guidance conduit with dynamic 3D interconnected porous network and sustained IGF-1 delivery for enhanced peripheral nerve regeneration and immune modulation.

Recent advancements in tissue engineering have promoted the development of nerve guidance conduits (NGCs) that significantly enhance peripheral nerve injury treatment, improving outcomes and recovery rates. However, utilising tailored biomimetic three-dimensional (3D) topological porous structures combined with multiple bio-effect neurotrophic factors to create environments similar to neural tissues, regulate local immune responses, and develop a supportive microenvironment to promote peripheral nerve regeneration and repair poses significant challenges. Herein, a biomimetic extracellular matrix (ECM) NGC featuring an interconnected 3D porous network and sustained delivery of insulin-like growth factor-1 (IGF-1) is designed using multi-functional gelatine microcapsules (GMs).

Exposure to Perinatal Trauma Modifies Nociception and Gene Expression in the Prefrontal Cortex and Hypothalamus of Adolescent Rats.

The perinatal period encompasses a critical window for neurodevelopment that renders the brain highly responsive to experience. Trauma, such as intimate partner violence (IPV) and early life stress/neglect, during this period negatively affects physical and mental health outcomes, including increasing ones risk for chronic pain. Although epigenetic programming likely contributes, the mechanisms that drive the relationship between perinatal trauma and adverse health outcomes, are not fully understood.

Developing a codebook for assessing auditory hallucination complexity using mixed methods.

Introduction: In recent years there has been a notable expansion of psychotherapeutic approaches to treat people experiencing auditory verbal hallucinations (AVH). While many psychotherapists conceptualize voices as "dissociative parts" and apply therapeutic techniques derived from the field of dissociation, research investigating AVH from this perspective is limited. Despite the acknowledgment that voices encountered in dissociative identity disorder (DID) often exhibit high complexity and autonomy, there is a critical need for assessment tools capable of exploring voice complexity across different clinical groups.

Presenting predictions and performance of probabilistic models for clinical decision support in trauma care.

Introduction: Both predictions and performance of clinical predictive models can be presented with various verbal and visual representations. This study aims to investigate how different risk and performance presentations for probabilistic predictions affect clinical users' judgement and preferences.

Methods: We use a clinical Bayesian Network (BN) model that has been developed for predicting the risk of Trauma Induced Coagulopathy (TIC).

Associations Between Instrumented Mouthguard-Measured Head Acceleration Events and Post-Match Biomarkers of Astroglial and Axonal Injury in Male Amateur Australian Football Players.

Background: Advances in instrumented mouthguards (iMGs) allow for accurate quantification of single high-acceleration head impacts and cumulative head acceleration exposure in collision sports. However, relationships between these measures and risk of brain cell injury remain unclear.

Aim: The purpose of this study was to quantify measures of non-concussive head impact exposure and assess their association with blood glial fibrillary acidic protein (GFAP), neurofilament light (NfL) and phosphorylated-tau-181 (p-tau-181) levels in male Australian football players.

Early high-dose cryoprecipitate to reduce mortality in adult patients with traumatic haemorrhage: the CRYOSTAT-2 RCT with cost-effectiveness analysis.

Background: Traumatic haemorrhage is common after severe injury, leading to disability and death. Cryoprecipitate, a source of fibrinogen, may improve outcomes for patients with traumatic haemorrhage.

Objective: To investigate the effects of early fibrinogen supplementation in the form of 3 pools (15 units, approximately 6 g of fibrinogen) of cryoprecipitate on 28-day mortality.

Implantable and transcutaneous photobiomodulation promote neuroregeneration and recovery of lost function after spinal cord injury.

Spinal cord injury (SCI) is a cause of profound and irreversible damage, with no effective therapy to promote functional recovery. Photobiomodulation (PBM) may provide a viable therapeutic approach using red or near-infrared light to promote recovery after SCI by mitigating neuroinflammation and preventing neuronal apoptosis. Our current study aimed to optimize PBM dose regimens and develop and validate the efficacy of an invasive PBM delivery paradigm for SCI.

Counterfactual reasoning using causal Bayesian networks as a healthcare governance tool.

Background: Healthcare governance (HG) is a quality assurance processes that aims to maintain and improve clinical practice. Clinical decisions are routinely reviewed after the outcome is known to learn lessons for the future. When the outcome is positive, then practice is praised, but when practice is suboptimal, the area for improvement is highlighted.

A scoping review, novel taxonomy and catalogue of implementation frameworks for clinical decision support systems.

Background: The primary aim of this scoping review was to synthesise key domains and sub-domains described in existing clinical decision support systems (CDSS) implementation frameworks into a novel taxonomy and demonstrate most-studied and least-studied areas. Secondary objectives were to evaluate the frequency and manner of use of each framework, and catalogue frameworks by implementation stage.

Methods: A scoping review of Pubmed, Scopus, Web of Science, PsychInfo and Embase was conducted on 12/01/2022, limited to English language, including 2000-2021.

A novel spine tester TO GO.

Background: Often after large animal experiments in spinal research, the question arises-histology or biomechanics? While biomechanics are essential for informed decisions on the functionality of the therapy being studied, scientists often choose histological analysis alone. For biomechanical testing, for example, flexibility, specimens must be shipped to institutions with special testing equipment, as spine testers are complex and immobile. The specimens must usually be shipped frozen, and, thus, biological and histological investigations are not possible anymore.

Comparing the effectiveness and safety of videolaryngoscopy and direct laryngoscopy for endotracheal intubation in the paediatric emergency department: a systematic review and meta-analysis.

Introduction: Endotracheal intubation is an uncommon procedure for children in the emergency department but can be technically difficult and cause significant adverse effects. Videolaryngoscopy (VL) offers improved first-pass success rates over direct laryngoscopy (DL) for both adults and children undergoing elective surgery. This systematic review was designed to evaluate current evidence regarding how the effectiveness and safety of VL compares to DL for intubation of children in emergency departments.

Pathophysiology, blood biomarkers, and functional deficits after intimate partner violence-related brain injury: Insights from emergency department patients and a new rat model.

Intimate partner violence is a serious, but underappreciated, issue that predominantly affects women and often results in concussion (i.e., mild traumatic brain injury).

Papain Injection Creates a Nucleotomy-like Cavity for Testing Gels in Intervertebral Discs.

Biomaterials, such as hydrogels, have an increasingly important role in the development of regenerative approaches for the intervertebral disc. Since animal models usually resist biomaterial injection due to high intradiscal pressure, preclinical testing of the biomechanical performance of biomaterials after implantation remains difficult. Papain reduces the intradiscal pressure, creates cavities within the disc, and allows for biomaterial injections.

Plasma biomarkers in chronic single moderate-severe traumatic brain injury.

Blood biomarkers are an emerging diagnostic and prognostic tool that reflect a range of neuropathological processes following traumatic brain injury (TBI). Their effectiveness in identifying long-term neuropathological processes after TBI is unclear. Studying biomarkers in the chronic phase is vital because elevated levels in TBI might result from distinct neuropathological mechanisms during acute and chronic phases.

How cervical and cervicothoracic scoliosis influence the atlantoaxial joint.

Introduction: Children with cervical or cervicothoracic congenital scoliosis are limited in their ability to compensate for the main curve of the deformity because there are only a few mobile segments in their cervical spine. Over the years, we have frequently observed coronal atlantoaxial dislocation (CAAD) in a lateral direction (from left to right or vice versa) in these patients. It was anticipated that CAAD might compensate for the horizontal position of the head, and it is hypothesized that CAAD depends on the degree of scoliotic deformity.

Cumulative sum (CUSUM) analysis: A 10 year experience of outcome monitoring in a regional burn centre.

Introduction: Outcome monitoring can identify fluctuations in healthcare. Cumulative sum (CUSUM) analysis can detect when mortality deviates from expected, allowing early intervention through targeted audit. We present a 10-year experience of the prospective use of CUSUM methodology in a regional burn centre.

Current Concepts in Management of Distal Femur Fractures.

Recent studies report the overall incidence of distal femur fractures as 8.7/100,000/year. This incidence is expected to rise with high energy motor vehicle collisions and elderly osteoporotic fractures in native and prosthetic knees keep increasing.

Background: Equine-assisted services (EAS) involves the use of horses within therapy, learning or horsemanship sessions and has been used with military veterans suffering from post-traumatic stress disorder (PTSD). This study systematically reviewed existing research on the use of EAS in the treatment of PTSD in military veterans and evaluated its effectiveness.

Methods: A systematic review was performed, in May 2023, with searches and data extraction carried out from three separate databases (PubMed, JSTOR and Science Direct) related to testing the effect of EAS on PTSD outcomes in veterans.

Management of Traumatic Cerebral Venous Sinus Thrombosis: A United Kingdom and Ireland Survey on Practice Variation.

Traumatic cerebral venous sinus thrombosis (tCVST) is an increasingly recognized sequela of traumatic brain injury (TBI), with skull fractures and extradural hematomas overlying venous sinuses recognized as risk factors. Although it may be treated with anticoagulation, the decision to treat tCVST is nuanced by the risk of new or worsening hemorrhage. Presently, there are no guidelines on the investigation and management of tCVST.
