The frontal aslant tract (FAT) is a bilateral tract located within each frontal lobe. It connects the supplementary motor area in the superior frontal gyrus with the pars opercularis in the inferior frontal gyrus. There is a new and broader conceptualization of this tract called the extended FAT (eFAT). The eFAT tract role is believed to be related to several brain functions, including verbal fluency as one of its main domains. ⋯ The tract was successfully reconstructed, focusing on its morphology and anatomic characteristics.

To investigate poor outcomes of aneurysmal subarachnoid hemorrhage (aSAH) and compare the clinicodemographic characteristics, imaging features, intervention strategies, laboratory tests, and complications of patients with good and poor outcomes to identify potential risk factors. ⋯ Outcomes at discharge varied according to ethnic group. Han patients had worse outcomes. Age, loss of consciousness at onset, systolic blood pressure on admission, Hunt-Hess grade 4-5 on admission, epileptic seizures, modified Fisher grade 3-4, microsurgical clipping, size of the ruptured aneurysm, and cerebrospinal fluid replacement were independent risk factors for aSAH outcomes.

Facet joint orientation (FJO) and facet joint tropism (FJT) are associated with intervertebral disc degeneration and paraspinal muscle atrophy. However, none of the previous studies has evaluated the association of FJO/FJT with fatty infiltration in the multifidus, erector spinae, and psoas muscles at all lumbar levels. In the present study, we aimed to analyze whether FJO and FJT were associated with fatty infiltration in the paraspinal muscles at any lumbar level. ⋯ Sagittally oriented facet joints at lower lumbar levels could be associated with fattier erector spinae and psoas muscles at lower lumbar levels. The erector spinae at upper lumbar levels and psoas at lower lumbar levels might have become more active to compensate the FJT-induced instability at lower lumbar levels.

The C-reactive protein/albumin ratio (CAR), Glasgow coma scale score, and blood glucose level serve as reference values to evaluate the prognosis of critically ill patients. However, the prognostic significance of the admission serum CAR for patients with moderate to severe traumatic brain injury (TBI) has remained unclear. We examined the effect of the admission CAR on the outcomes of patients with moderate to severe TBI. ⋯ The CAR can serve as an independent risk factor of mortality for patients with moderate to severe TBI. Incorporating CAR into a predictive model could contribute to efficiently predicting the prognosis of adults with moderate to severe TBI.
