Frontal crash seat belt restraint effectiveness and comfort accessories used by older occupants.

Conclusions: Accessories placed between the seat back and the lumbar region of an occupant have the potential to increase the risk of submarining due to a change in posture and should be avoided if such a change in posture when seated with an accessory is excessive. Sitting on seat cushions resulted in the greatest increase in seat belt anchor to hip distances and hence largest increase in sternal deflection. Given the fragility, frailty and particular importance of chest injuries among older vehicle occupants, further investigation is needed to determine whether these changes in ATD sternal deflection observed with seat cushion use results in injury threshold limits being exceeded and whether pretensioners and load limiters would ameliorate these effects without causing other negative changes in occupant response or kinematics.

CONCLUSIONS: Opioid dependence is associated with impairments in decision making, executive function, working memory, and attention. Co-morbid cannabis dependence had similar profiles of cognitive impairments. SCIENTIFIC SIGNIFICANCE: Co-morbid cannabis dependence might not add on to the existing cognitive dysfunction in opioid dependence. Further studies should be done with a larger sample.

Conclusion: In conclusion, observed differences between the occupant models' head injury metric output were quantified. Loading direction had a large effect on metric outcome and metric comparability across models, with frontal and rear impacts with low vertical acceleration tending to be the most similar. One explanation for these differences could be the differences in neck stiffness between the models that allowed more rotation in the GHBMC and THOR. Care should be taken when using ATDs as human volunteer surrogates in these low energy events. PMID: 31951749 [PubMed - as supplied by publisher]

AbstractPurpose of ReviewThis review informs the practicing clinician regarding the pathophysiology of mild traumatic brain injury and its implication on the anesthetic management of patients presenting for surgery. It highlights several areas where data is sparse that might spark the interest of researchers. It proposes a broad guideline for managing patients who present for surgery.Recent FindingsThe post-concussive brain has a vulnerable window of risk in which secondary insult might worsen long-term outcome. Scheduling elective surgery beyond this window of vulnerability might be beneficial. Several biomarkers may prov...
