Article Abstract
Background: Spinal cord ischemia is a major complication of treatment for descending thoracic aorta (DTA) disease. Our objectives were (1) to describe the value of angiographic cone-beam CT (angio-CBCT) and 3D road-mapping to visualize the Adamkiewicz artery (AA) and its feeding artery and (2) to evaluate the impact of AA localization on the patient surgical strategy.
Methods: Between 2018 and 2020, all patients referred to our institution for a surgical DTA disorder underwent a dedicated AA evaluation by angio-CBCT. If the AA feeding artery was not depicted on angio-CBCT, selective artery catheterization was performed, guided by 3D road-mapping. Intervention modifications, based on AA location and one month of neurologic follow-up after surgery, were recorded.
Results: Twenty-one patients were enrolled. AA was assessable in 100% of patients and in 15 (71%) with angio-CBCT alone. Among them, 10 patients needed 3D road-mapping-guided DSA angiography to visualize the AA feeding artery. The amount of contrast media, irradiation dose, and intervention length were not significantly different whether the AA was assessable or not by angio-CBCT. AA feeding artery localization led to surgical sketch modification for 11 patients.
Conclusions: Angio-CBCT is an efficient method for AA localization in the surgical planning of DTA disorders.

Effects of isoflavone supplementation, via red clover hay, on the growth and postgraze physiological recovery of beef steers grazing endophyte-infected tall fescue pastures.

Livestock grazing endophyte-infected (E+) tall fescue can exhibit persistent systemic vasoconstriction and fescue toxicosis. Isoflavones in legumes, most notably red clover (RC), are known hypotensive agents. The objective of the experiment was to evaluate the effect of isoflavone supplementation via RC hay, every day or every other day (QOD), on average daily gain (ADG) of steers grazing E+ tall fescue pastures and their physiological recovery after grazing when managed on a non-toxic diet (28-d).

Superior mesenteric artery (SMA) syndrome is a rare condition characterized by the narrowing of the space between the SMA and the aorta, resulting in the compression of the third portion of the duodenum. This syndrome has many names, including cast syndrome, arterio-mesenteric duodenal compression syndrome, and Wilkie syndrome. This is attributed to the loss of the intervening mesenteric fat pad, posing diagnostic and therapeutic challenges due to its nonspecific presentation.

Aims: To determine the optimal extent of lymph node dissection for non-metastatic colon cancer by tumor location based on the therapeutic value index (TVI) for each lymph node station.
Methods: Consecutive patients with surgical stage I-III colon or rectosigmoid cancer in the Japanese Society for Cancer of the Colon and Rectum database who underwent curative resection between January 2003 and December 2014 were analyzed. The TVI was defined as the incidence of lymph node metastasis multiplied by 5-year overall survival and calculated for each nodal station stratified by tumor location.

Background: The liver cone unit (Tokyo 2020 terminology) of the peripheral portal vein territory represents the smallest anatomical and functional unit of the liver. While this unit enables anatomical, subsegmental resection, particularly in patients with cirrhosis, the tumor-bearing cone unit can be challenging to identify intraoperatively. PATIENTS AND METHODS: A 58-year-old man with hepatitis C-related cirrhosis (Child-Pugh B) was diagnosed with a subcapsular hepatocellular carcinoma (HCC) in segment 8.

Cardiometabolic syndrome (CMS) encompasses a cluster of metabolic abnormalities, including obesity, insulin resistance, dyslipidemia, and hypertension that collectively increase the risk of cardiovascular disease and type 2 diabetes. Animal models are widely used to study CMS, with diet-induced models being the most physiologically relevant. A lack of reporting standards and variability in dietary composition, feeding duration, and macronutrient content across studies hinder reproducibility assessment and translational impact evaluation.
