Summary: In recent years, microfluidics has been crucial to the advancement of nerve regeneration research. Microfluidic devices accurately simulate the in vivo microenvironment for various research purposes such as analyzing growth inhibitory factors, screening drugs, evaluating nerve growth factors, and investigating neural injury and regeneration mechanisms. The platform enables precise control of cell behavior, such as neuron isolation, single-cell manipulation, neural patterning, and axon guidance, providing technical support for nerve regeneration.

Summary: Neurodegenerative diseases and neurotraumatic injuries can lead to the loss of neurological functions. Using current screening methods with neurons that do not match the age and sex of the target population is a barrier for translational success. By modifying the processing method of adult neurons, we have developed age- and sex-appropriate models for in vitro screening, which greatly increases the relevance of finding neuroprotective compounds.

Summary: Sterile inflammation in the eye can partially reverse the failure of mammalian retinal ganglion cells (RGCs) to regenerate axons and survive after optic nerve injury. This reversal is mediated by the expression of axogenic protein oncomodulin (Ocm) by infiltrative myeloid cells. Additionally, stromal cell-derived factor 1 (SDF1) expressed by infiltrative macrophages plays a central role in enhancing Ocm activity and promoting inflammation-induced regeneration and RGC survival.

Summary: This review discusses the heterogeneity of retinal ganglion cells (RGCs) and their differential resilience to injury and regeneration. By identifying molecular features and studying different regeneration models, specific RGC types that exhibit preferential survival and regeneration have been discovered. Cellular characteristics and the selective expression of certain genes may contribute to their reparative capacity. These studies lay an important groundwork for identifying factors that promote neural regeneration and developing targeted therapy for RGC degeneration and neurodegenerative diseases in general.

Summary: Reactive gliosis, characterized by increased expression of S100 beta and intermediate filaments (GFAP, vimentin, and nestin), plays a significant role in tissue repair during retinal degeneration. The expression of gliotic markers was elevated in the damaged area of both mouse and human retinal samples. In zebrafish, the expression of S100 beta was detected earlier than GFAP and nestin. The different expression patterns of intermediate filaments suggest that targeting S100 beta may help suppress chronic gliosis in retinal degeneration.

Summary: Tracheal tube introducers and stylets are effective aids for intubation in the prehospital environment, with bougies having a statistical advantage in first pass ETI success when video technology is available, while stylets lead to shorter intubation times and are easier to use. There is no statistical difference in success rates and complication rates between different devices, and device selection may ultimately depend on the clinical scenario, practitioner expertise, and personal preference.

Summary: Traumatic brain injury (TBI) is a global health problem, and there is currently a lack of therapeutics to improve survival and outcomes. Current neuromonitoring methods cannot accurately reflect the complex pathophysiological processes occurring after TBI. Raman spectroscopy (RS) is a powerful optical tool that can provide detailed biochemical data in vivo. This systematic review evaluates the evidence for the use of RS in TBI and highlights its potential in identifying injury severity and metabolic dysfunction.

Summary: Ventilation strategies for primary blast lung injury (PBLI) should aim to minimize lung injury by utilizing conventional low tidal volume ventilation, airway pressure release ventilation, and high frequency oscillatory ventilation. Conventional low tidal volume ventilation with variable positive end-expiratory pressure and permissive hypercapnia has shown to reduce inflammation and mortality. Airway pressure release ventilation has the potential to reduce dynamic strain and extravascular lung water while encouraging spontaneous breathing. High frequency oscillatory ventilation is able to effectively avoid lung injury but may not necessarily reduce mortality.

Summary: This study aimed to explore the efficacy and safety of localised insulin administration on wound healing in non-diabetic adults. The findings showed a significant improvement in wound healing rate in the insulin treated group, but other parameters were not statistically significant. Therefore, larger prospective studies are needed to fully investigate the effects of insulin on different wounds.

Summary: Carpal tunnel syndrome (CTS) is a common condition that causes numbness and weakness in the hand and arm. Neurodynamic modulation techniques have been used as a non-surgical treatment for CTS, but their effectiveness has been unclear. This systematic review found that neurodynamic techniques significantly reduced symptom severity, pain, and motor latency in CTS patients, while improving nerve conduction velocities.

Summary: Cerebral small vessel disease is characterized by decreased cerebral blood flow and blood-brain barrier impairments, leading to the development of white matter lesions. Cerebral hypoperfusion induces hypoxia and affects the signaling between oligodendrocyte precursor cells and endothelial cells, resulting in blood-brain barrier dysfunction. In this study, a mouse model of cerebral hypoperfusion was used to investigate the role of hypoxia-induced VEGFA expression in the development of white matter lesions. The results suggest that VEGFA upregulation in hypoxic oligodendrocyte precursor cells mediates blood-brain barrier permeability, which is associated with increased VEGFA plasma levels in cerebral small vessel disease patients.

Summary: This study found that the overexpression of DYRK1A protein in Down syndrome mice varies with age, sex, and brain region, and reducing the copy number of Dyrk1a can decrease the expression of DYRK1A. These sex-specific patterns of DYRK1A overexpression may provide mechanistic targets for therapeutic intervention in Down syndrome.
