Background: This study evaluates the utility of CT angiography (CTA) and the Expanded Denver Criteria (EDC) in detecting blunt cerebrovascular injuries (BCVI) in blunt cervical trauma, assaults, and strangulation. Methods: A retrospective review of 748 patients undergoing CTA for blunt cervical trauma, assaults, and strangulation (2013–2023) was conducted. After exclusions, 344 CTA reports were analyzed. Inclusion criteria: patients ≥18 years with complete medical records who underwent CTA for trauma evaluation. Exclusions: penetrating injuries, preexisting cerebrovascular abnormalities, incomplete records, or CTA not performed. Results: BCVI was identified in 38/344 cases (11%), with 55% classified as Grade I (Biffl). Posterior circulation (71%) and internal carotid arteries (36.8%) were most affected. Eight BCVI cases (21%) did not meet EDC; MVCs accounted for seven. MVCs (68%) and falls (29%) were the leading causes, while no BCVIs were observed in assaults or strangulations. Conclusions: MVCs and high-impact falls pose the highest BCVI risk, warranting CTA beyond EDC indications. In contrast, CTA may be less necessary for assaults and strangulations. Further studies across trauma centers are needed to confirm these findings.

Seventy Duroc × Landrace weanling pigs (initial weight 20 kg) were used in a 91-day experiment in a semi-tropical environment, to determine the effects of deletion of the vitamin-antibiotic or mineral supplement to a corn-sucrose-soya bean meal diet on performance of pigs in Coastal Bermuda grass pasture lots. Pigs fed the complete diet in confinement in concrete-floor pens had significantly faster body-weight gain than pigs fed the same diet on pasture. Pigs fed the complete diet on pasture gained weight significantly faster than those given the same diet but without a vitamin-antibiotic premix. Those fed the complete diet without a Ca-P-trace mineral supplement on pasture gained weight significantly more slowly than all other groups, and showed lameness and femur and rib fractures (2 animals) indicative of Ca deficiency rickets.
