To determine whether skip metastases (SM) in high-grade appendicular osteosarcoma (HG-OS) are an indicator of more aggressive disease. Retrospective review of patients with histologically confirmed diagnosis HG-OS of the long bones from 2007 to 2020, who had whole-bone MRI to identify SM. Data collected included patient age/gender, bone involved, the presence of SM, the presence of lung metastases from chest CT, the presence of distant bone metastases from whole-body bone scintigraphy or whole-body MRI, and chemotherapy response from resection specimen histology. The presence of lung or bone metastases and chemotherapy response were compared between patients without and with SM. The study included 241 patients (146 males; 95 females mean age 18.2years; range 4-73years). Based on whole-bone MRI, 202 (83.8%) patients had no SM and 39 (16.2%) patients had a SM. Of patients without a SM, lung metastases were identified in 44 (22%) and distant bone metastases in 6 (3%) cases, while 80 (43%) had a good chemotherapy response and 105 (57%) had a poor chemotherapy response. Of patients with a SM, lung metastases were identified in 22 (58%) and distant bone metastases in 8 (21%) cases, while 11 (32%) had a good chemotherapy response and 23 (68%) had a poor chemotherapy response. The presence of SM was significantly associated with both lung metastases (p < 0.001) and skeletal metastases (p < 0.001), but not with chemotherapy response (p = 0.24). Patients with SM also had poorer survival (p < 0.001). The presence of SM in appendicular HG-OS suggests more aggressive disease. The presence of SM in appendicular HG-OS suggests more aggressive disease.Although lithium-ion batteries are broadly applied for various purposes, they suffer from safety problems, high cost, and short life. Due to widespread availability, low cost, and nontoxicity of potassium, potassium ion batteries (PIBs) can be applied instead of lithium-ion batteries. Here, dispersion-corrected B3LYP calculations were used to explore potential application of pristine carbon nanocone (CNC) as well as its B- and N-doped models in PIBs. The K cation and K atom were adsorbed onto the center of the apex ring of CNC, and the energies of adsorption were - 19.3 and - 9.0 kcal/mol. The CNC creates a cell voltage of 0.44 V as an anode material which is very small. We showed that substituting some C atoms of CNC by the electron-rich N atoms makes the nanocone more appropriate for application in the PIBs, while B-doping meaningfully decreases the cell voltage. The cell voltage created by the considered nanocones in the PIBs has the following order N-CNC (~ 1.24 V) > CNC (~ 0.45 V) > > B-CNC (~ 0.24 V). This work illustrated that the N-CNC may be a promising electrode material for PIBs. Recent work suggests patients with moderately depressed Glasgow Coma Scale (GCS) score in the Emergency Department (ED) who do not undergo immediate head CT (CTH) have delayed neurosurgical intervention and longer ED stay. The present study objective was to determine the impact of time to first CTH on functional neurologic outcomes in this patient population. Blunt trauma patients presenting to our Level I trauma center (11/2015-10/2019) with first ED GCS 9-12 were retrospectively identified and included. Transfers and those with extracranial AIS ≥ 3 were excluded. The study population was stratified into Immediate (≤ 1 h) and Delayed (1-6 h) CTH groups based on time from ED arrival to first CTH. MLSI3 Outcomes included functional outcomes at hospital discharge based on the Modified Rankin Scale (mRS). After exclusions, 564 patients were included 414 (73%) with Immediate CTH and 150 (27%) Delayed CTH. Both groups arrived with median GCS 11 and alcohol/drug intoxication did not differ (p > 0.05).
