ReviewParental Factors Associated with Recovery after Mild Traumatic Brain Injury: A Systematic Review.
While parental factors have been shown to potentially influence recovery after mild traumatic brain injury (mTBI) in children, both the strength and direction of the relationships remain unclear. We performed a systematic review regarding the association between parental factors and recovery after mTBI. PubMed, CINHL, Embase, PsychINFO, Web of Science, ProQuest, Cochrane Central, and Cochrane databases were queried for articles published between September 1, 1970, and September 10, 2022, reporting any parental factor and its association with recovery after mTBI in children younger than 18 years old. ⋯ The current review highlights literature describing several parental factors that significantly influence recovery from mTBI. It will likely be useful for future studies to incorporate parental SES, education, stress/distress, anxiety, quality of parent-child relationships, and parenting style when examining modifying factors in recovery after mTBI. Future studies should also consider how parental factors may serve as potential interventions or policy levers to optimize sport concussion-related policy and return-to-play guidelines.

Introduction/Aims: Traumatic brain injuries (TBIs) are one of the leading causes of death and disability in children and adolescents. A significant number of those who survive suffer from the lasting cognitive, physical, or behavioral effects of TBI while the loss is devastating for families. The aim of the study is to characterize the pediatric population and formulate referral criteria for palliative care (PC) consults who would guide the most beneficial allocation of resources. ⋯ Discussion: PC programs are a finite resource and should be available to and focused on those with greatest need. The proposed criteria provide empirically based guidance on when to consult, or consider consulting, specialist pediatric PC. Further testing of these criteria and their relationship with improved outcomes are desirable.

Traumatic brain injury (TBI) is a leading cause of death and disability worldwide. Pathophysiological processes following initial insult are complex and not fully understood. Ionized calcium (Ca++) is an essential cofactor in the coagulation cascade and platelet aggregation, and hypocalcemia may contribute to the progression of intracranial bleeding. On the other hand, Ca++ is an important mediator of cell damage after TBI and cellular hypocalcemia may have a neuroprotective effect after brain injury. We hypothesized that early hypocalcemia might have an adverse effect on the neurological outcome of patients suffering from isolated severe TBI. In this study, we aimed to evaluate the relationship between admission Ca++ level and the neurological outcome of these patients. ⋯ Our study demonstrates that among patients with isolated severe TBI, mild admission hypocalcemia is associated with better neurological status at hospital discharge. The prognostic value of Ca++ may be greater among patients with admission Glasgow Coma Scale > 8. Trials are needed to investigate the role of hypocalcemia in brain injury.

Fixed time point analysis reveals repetitive mild traumatic brain injury effects on resting state fMRI connectivity and neuro-spatial protein profiles.
Repetitive mild traumatic brain injuries (rmTBIs) are serious trauma events responsible for the development of numerous neurodegenerative disorders. A major challenge in developing diagnostics and treatments for the consequences of rmTBI is the fundamental knowledge gaps of the molecular mechanisms responsible for neurodegeneration. It is both critical and urgent to understand the neuropathological and functional consequences of rmTBI to develop effective therapeutic strategies. ⋯ Our analyses revealed aberrant connectivity changes in the thalamus, independent of microstructural damage or neuroinflammation. We also identified distinct changes in the levels of proteins linked to various neurodegenerative processes including total and phospho-tau species and cell proliferation markers. Together, our data show that rmTBI significantly alters brain functional connectivity and causes distinct protein changes in morphologically intact brain areas.

Observational Study
Creatinine Clearance in Acute Brain Injury: A Comparison of Methods.
Currently, the measurement of glomerular filtration rate is very complex and costly, so its daily evaluation is performed using endogenous markers, of which creatinine is the most frequently used. It allows the estimation of glomerular filtration rate by means of its clearance or by formulas based on its serum and urine concentration. Augmented renal clearance (ARC) is frequent among critically ill patients and is defined as creatinine clearance (CrCl) > 130 ml/min/1.73 m2. The aim of this study was to compare measured CrCl (MCC) and estimated CrCl obtained with the Cockcroft-Gault formula (CG), the Modification of Diet in Renal Disease Study equation (MDRD), and the Chronic Kidney Disease Epidemiology Collaboration formula (CKD-EPI) in patients with severe traumatic brain injury and nontraumatic subarachnoid hemorrhage. The second aim was to assess the incidence of ARC in this population of neurocritical patients. ⋯ In this population, there was a weak statistical correlation between measured and estimated methods. In patients with ARC, formulas underestimated MCC. MCC should probably be the preferred methodology for renal function assessment in the clinical setting to better adjust drug dosage and guarantee drug effectiveness.
