Article Abstract
Preoperative ankle/arm indices were determined in 104 lower extremities from 53 patients who underwent prosthetic graft placement for abdominal aortic aneurysms. Sixty-nine percent of the limbs (group 1) had a normal index; 31% of the limbs (group 2) had indices indicative of arterial occlusive disease. Early postoperative ankle/arm indices were determined in 87 limbs (57 in group 1 and 30 in group 2). Twelve group 1 limbs exhibited a postoperative decrease in the index. In group 2, four of the five decreases were seen when the distal anastomosis was placed above the inguinal ligament, while all 17 group 2 limbs in which the index increased had the distal anastomoses performed at the common femoral level. In 1.8% of the group 1 limbs and 6.7% of the group 2 limbs, a subsequent arterial procedure below the inguinal ligament was required. An additional 1.8% of group 1 limbs and 6.7% of group 2 limbs had undergone a distal arterial procedure prior to aneurysm resection.

Impact of single versus dual arterial supply on perfusion and function in finger replantation after complex hand injuries.
Sci Rep

Department of Plastic, Aesthetic, Hand and Reconstructive Surgery, Hannover Medical School, Carl-Neuberg-Str. 1, D-30625, Hannover, Germany.
Finger amputations following complex hand injuries (CHI) pose a significant challenge in hand surgery due to severe tissue trauma and neurovascular damage, necessitating precise arterial repair. While restoring arterial perfusion is critical, it remains unclear whether reconstructing both proper palmar digital arteries is required for optimal outcomes. This study evaluates whether restoring one or both arteries in finger replantation after complex injuries impacts perfusion and overall outcomes.

Background: Children with fractured limbs usually have moderate to high pain, and distraction can help reduce their pain and anxiety. Virtual reality technology is an emerging method of distraction. We investigated whether the use of immersive virtual reality gaming technology to treat perioperative pain in children with school-age limb fractures effectively.

Laboratory for the Study of Tactile Communication, Pushkin State Russian Language Institute, 117485 Moscow, Russia.
Background: The significance of tactile stimulation in human social development and personal interaction is well documented; however, the underlying cerebral processes remain under-researched. This study employed functional magnetic resonance imaging (fMRI) to investigate the neural correlates of social touch processing, with a particular focus on the functional connectivity associated with the aftereffects of touch.
Methods: A total of 27 experimental subjects were recruited for the study, all of whom underwent a 5-minute calf and foot massage prior to undergoing resting-state fMRI.
Specific Physical and Nutritional Preparation of a Professional Kata Karate Athlete: A Case Study with a Bronze Medallist from the Pan American Games.

Physical and Sports Performance Research Centre, Faculty of Sports Sciences, Pablo de Olavide University, 41013 Seville, Spain.
Background And Objectives: In karate, particularly in the kata discipline, there is a notable lack of studies focused on specific physical preparation for competitions. This highlights an urgent need for more in-depth research into this crucial aspect of athletic training to optimize performance and athlete preparation. The objective of this study was to analyze the influence of a dietary plan combined with specific physical preparation on the performance and body composition of a professional kata athlete preparing for a Pan American championship.

Objective: This study aimed to investigate the effects of a 12-week self-designed exercise game intervention on the kinematic and kinetic data of the supporting leg in preschool children during the single-leg jump.
Methods: Thirty 5- to 6-year-old preschool children were randomly divided into an experimental group (EG) and a control group (CG). The BTS SMART DX motion capture analysis system was used to collect single-leg jump data before the intervention.
