Hemotherapy performed in our clinic was investigated in patients operated on in the years 1973 and 1982. A total of 832 operations (638 gynaecological interventions and 194 cesarean sections) were used for evaluation. - Transfusion rates decreased from 72% (1973) to 13% (1982) due to systematic application of crystalloid and colloidal infusions to cases of blood loss of up to 20% of the total blood volume. The percentage of erythrocyte concentrate applied increased from 0.4% (1973) to 42% (1982), while it even reached 80% when related to the total blood transfusions of our clinic. To conclude, strict principles should be adopted in deciding for blood transfusion as well as in purposefully applying blood constituents lost. The advantageous development in the economy of surgery is outlined.

Objective: The potential of robot-assisted (RA) single-position (SP) lateral lumbar interbody fusion (LLIF) warrants further investigation. This study aimed to assess the efficacy of RA-SP-LLIF in improving both clinical and radiographic outcomes in patients undergoing lumbar spinal fusion surgery.
Methods: A total of 59 patients underwent either RA-SP-LLIF (n = 31 cases) or traditional LLIF (n = 28 cases).
Evaluation of Jaundice in Adults.

Jaundice is an indication of hyperbilirubinemia and is caused by derangements in bilirubin metabolism. It is typically apparent when serum bilirubin levels exceed 3 mg/dL and can indicate serious underlying disease of the liver or biliary tract. A comprehensive medical history, review of systems, and physical examination are essential for differentiating potential causes such as alcoholic liver disease, biliary strictures, choledocholithiasis, drug-induced liver injury, hemolysis, or hepatitis.

Background: Teaching severe pelvic trauma poses a significant challenge in orthopedic surgery education due to the necessity of both clinical reasoning and procedural operational skills for mastery. Traditional methods of instruction, including theoretical teaching and mannequin practice, face limitations due to the complexity, the unpredictability of treatment scenarios, the scarcity of typical cases, and the abstract nature of traditional teaching, all of which impede students' knowledge acquisition.
Objective: This study aims to introduce a novel experimental teaching methodology for severe pelvic trauma, integrating virtual reality (VR) technology as a potent adjunct to existing teaching practices.
Food groups, macronutrient intake and objective measures of total carotenoids and fatty acids in 16-to-24-year-olds following different plant-based diets compared to an omnivorous diet.

Background: Knowledge about the diet quality among youth who follow different types of plant-based diets is essential to understand whether support is required to ensure a well-planned diet that meets their nutritional needs. This study aimed to investigate how food groups, macronutrient intake, and objective blood measures varied between Norwegian youth following different plant-based diets compared to omnivorous diet.
Methods: Cross-sectional design, with healthy 16-to-24-year-olds (n = 165) recruited from the Agder area in Norway, following a vegan, lacto-ovo-vegetarian, pescatarian, flexitarian or omnivore diet.
BCAA interactions: how do they influence broiler performance, intestinal morphometry, lipid profile, and liver health?

An experiment was conducted to assess the effects of the BCAA and their interactions on performance, carcass composition, lipid metabolism, liver health, and intestinal morphometry in broiler chickens. Male chickens ( = 1080) were randomly assigned into floor pens in a 3 × 3 factorial design with 3 dietary ratios of SID Leu:Lys (110, 150, and 190%), and 3 dietary ratios of SID Ile-Val:Lys (68-77, 78-87, and 88-97%). Performance parameters were assessed from 1 to 35 days of age.
