Identification of patients with increased or decreased risk of intracranial bleeding is of clinical importance. The objective of this study was to evaluate the implication of cutaneous impact location (CIL) on the prevalence of intracranial injury after suspected or confirmed TBI irrespective of its severity.Methods: This was a retrospective, single-center, descriptive observational study of geriatric patients aged 65 years and older treated for suspected or confirmed TBI in a trauma surgery ED. The primary outcome of the study was the assessment of a CIL of the injury and its association with the prevalence of intracranial lesions found on a head computed tomography scan.Results: Among 381 patients included in the analysis, the CIL of interest (temporo-parietal and occipital impacts) was present among 178 (46.7%) cases. Thirty-six (9.5%) patients were diagnosed with intracranial bleeding. The prevalence of intracranial bleeding was higher in the CIL of interest group compared with other locations outside (12.9% vs 6.4%; p = 0.030). CIL of interest was a predictor of intracranial bleeding (p = 0.033; OR: 2.17; 95% CI: 1.06 to 4.42).Conclusion: The CIL of head injury is a predictor of intracranial lesions among geriatric patients with traumatic brain injury. Physicians should be aware of this association when assessing elderly patients with head injuries. More studies are needed to develop a clinical management tool incorporating CIL to guide the diagnosis of TBI in this population.Keywords: cutaneous impact location, traumatic brain injury, TBI, geriatric TBI

We explore the use of radiance fields (RFs) to reconstruct photorealistic 3D urban scenes, creating digital twins (DTs) for autonomous driving (AD) by leveraging Nerfacto and Splatfacto models integrated with the CARLA simulator. Our research demonstrates that publicly available RFs can be utilized through Nerfstudio library to create photorealistic urban scenes and extract arbitrary images based on the camera pose. These scenes can serve as simulations for AD or as DT repositories for static environments within the vehicular metaverse. Additionally, we quantitatively evaluate RF models and use masking to remove dynamic objects, successfully simulating real-world scenarios. Quantitative evaluation shows that the Splatfacto model achieves a peak signal-to-noise ratio (PSNR) of up to 26.40, a structural similarity index measure (SSIM) of 0.84, and a learned perceptual image patch similarity (LPIPS) score of 0.21, consistently outperforming the Nerfacto model.

Two new Re(iv) compounds of formulae H2tppz[ReCl6] (1) and [Cu(bpzm)2(μ-Cl)ReCl3(μ-ox)Cu(bpzm)2(μ-ox)ReCl3(μ-Cl)]n (2) [tppz = 2,3,5,6-tetrakis(2-pyridyl)pyrazine and bpzm = bis(pyrazolyl-1-yl)methane] have been prepared and their crystal structures determined by X-ray diffraction on single crystals. Compound 1 is a mononuclear species whose structure consists of octahedral hexachlororhenate(iv) anions and diprotonated H2tppz2+ cations which are arranged in the unit cell as alternating anionic and cationic layers, held together by electrostatic forces. The structure of 2 is made up of alternating [Cu(1)(bpzm)2]2+ and [(ox)ReCl3(μ-Cl)Cu(2)(bpzm)2(μ-Cl)ReCl3(ox)]2− entities interlinked by oxalate bridges to afford a neutral heterobimetallic chain. The oxalate group adopts the didentate (at Re)/monodentate (at Cu) bridging mode. The magnetic behavior of 1 and 2 has been investigated over the temperature range 1.9–295 K. 1 is a magnetically diluted Re(iv) complex, the relatively large value of the zero-field splitting of the ground level [D = −15.8(2) cm−1] accounting for the variation of χMT in the low temperature range. Weak intrachain ferromagnetic interactions between Re(iv) and Cu(ii) through oxalate (J1 = +0.15 cm−1) and single chloro (J2 = +4.9 cm−1) bridges occur in 2 which are obscured by the large zero-field splitting of the Re(iv) ion (DRe = 42 cm−1). In addition, interchain antiferromagnetic interactions are also involved in 2 which are responsible for the metamagnetic behavior observed, the value of the critical dc magnetic field (Hc) being 20 kOe.
