The return of raptors to Scotland's skies: Investigating the diets of reintroduced red kites and white-tailed eagles using stable isotopes.

Species reintroductions are increasingly seen as important methods of biodiversity restoration. Reintroductions of red kites Milvus milvus and white-tailed eagles Halieaeetus albicilla to Britain, which were extirpated in the late 19th and early 20th centuries, represent major conservation successes. Here, we measured stable isotope ratios of carbon (δ13C) and nitrogen (δ15N) in feather keratin and bone collagen of museum specimens of red kites and white-tailed eagles, which were collected from across Scotland between the 1800s and 2010s.

Background: Bipartite medial cuneiform bone (BMC) is located at the Lisfranc joint of the midfoot, and it represents a rare variant involving two separate ossification centers in the medial cuneiform bone. Although BMC is typically asymptomatic, it can become clinically relevant under conditions of trauma or chronic stress, affecting foot stability.
Case Report: The current imaging report describes a 48-year-old female presenting with chronic dorsal midfoot pain, worsened by extended standing and ambulation.
A novel load-sensing sliding hip screw to aid in the assessment of intertrochanteric fracture healing.

Bone healing after sliding hip screw internal fixation of intertrochanteric hip fractures is difficult to monitor with radiography. In this study, we describe and evaluate a device to non-invasively determine the loading on the screw implant as a possible qualitative indicator of bone healing. A novel load-sensing sliding hip screw (LS-SHS) was fabricated containing a radio-dense tungsten indicator rod that moves and can be measured within the screw cannulation when the screw bends under load via plain radiography.

- The study examined the use of Endoscopic Endonasal Trans-Sphenoidal Approach (EETA) for removing skull base tumors, specifically macro-adenomas, and assessed its effectiveness in terms of tumor resection and recurrence rates.
- Conducted over two years with 58 patients aged around 47, the results indicated a high success rate, with 84.4% achieving complete tumor removal, while 15.6% experienced recurrence.
- The findings suggest that EETA is a safe and effective method for treating macroadenomas, significantly contributing to the surgical management of these tumors.

Article Synopsis
- The study reviews advancements in 3D printed customized prostheses for acetabular reconstruction in hip revision surgeries, highlighting their design, manufacturing, and clinical applications.
- After an extensive review of literature, 48 relevant studies were analyzed, revealing that these 3D prostheses outperform traditional ones in bone growth and mechanical properties.
- The findings suggest that 3D printed prostheses enhance surgical accuracy and recovery, but further improvements in production techniques are needed for better long-term outcomes.
