Traumatic brain injury (TBI) is common and costly. Although neuroimaging modalities such as resting-state functional MRI (rsfMRI) promise to differentiate injured from healthy brains prognosticate long-term outcomes, the field suffers heterogeneous findings. To assess whether this heterogeneity stems variability in TBI populations studied or imaging methods used, determine a consensus exists literature, we performed first systematic review of studies comparing rsfMRI connectivity (FC) patients with matched controls for seven canonical networks across severity, age, chronicity, population type, various methods. Searching PubMed, Web Science, Google Scholar, ScienceDirect, 1,105 manuscripts were identified, 50 fulfilling our criteria.

It is increasingly evident that blood biomarkers have potential to improve the diagnosis and management of both acute chronic neurological disorders. The most well-studied candidates, arguably those with broadest utility, are proteins highly enriched in neural tissues released into circulation upon cellular damage. currently unknown how brain expression levels these influenced by demographic factors such as sex, race, age. Given source tissue abundance likely a key determinant observed during pathology, understanding influences important terms identifying clinical scenarios could produce diagnostic bias. In this study, we leveraged existing mRNA sequencing data originating from 2,642 normal specimens harvested 382 human donors examine variability genes which code for 28 candidate Existing mass spectrometry 26 additional separate was subsequently used tentatively assess whether transcriptional variance corresponding protein abundance. Genes associated several or emerging including neurofilament light chain (NfL), ubiquitin carboxyl-terminal hydrolase isozyme L1 (UCH-L1), neuron-specific enolase (NSE), synaptosomal-associated 25 (SNAP-25) exhibited significant differences respect many instances, align well provide mechanistic explanation previously reported levels.

Abstract Background Head impacts are common in contact sports such as boxing and occur at times of elevated core body brain temperatures induced by the exercise. Following impact, temperature may lead to development exacerbated injury that can be monitored blood biomarkers. We hypothesized acute head-and-neck cooling, recently shown shorten return-to-play concussed ice hockey players, applied acutely following a bout is associated with an attenuated release biomarkers improved symptom rating. Methods The trial academically driven funded external hospital research funds. Young, healthy elite boxers ≥ 18 years old recruited. Prior to, immediately after competitive over 3x2 or 3x3 minutes, samples drawn. Boxers randomized intervention control management 1:1 allocation prior baseline testing. After initial post-fight sample drawn rating using concussion assessment tool-5 (SCAT-5) has been collected, receive either selective cooling for 45 min, routine management. number head counted all on match video recordings. In both groups, minutes post-bout sample, well 3 6 days post-fight. At time points sampling, symptoms (NOS) severity score (SSS) assessed part SCAT-5. primary endpoint difference biomarker levels (GFAP, NF-L, tau, UCH-L1, neuronal-specific enolase) between pre-intervention levels, those obtained SCAT-5 NOS SSS secondary endpoints. Discussion There no treatment available boxing-induced injury. Biomarkers surrogate yet objective marker injury, attenuate injury-related reduce attained during fight. Potentially, option bout.
