Objective: To compare the outcomes of the fixation of complete and displaced supracondylar humeral fractures in children with two different Kirschner wire configurations.
Methods: The type of fixation was randomized to either crossed (19 cases), or two divergent lateral Kirschner wires (24 cases). The comparison was made six months later between the two treated groups and each group with the non-fractured elbow (clinical alignment, range of motion, Baumann angle, and lateral humeral capitellar angle).
Results: 43 children were evaluated (65% boys) with a mean age of six years and five months. The carrying angle (p = 0.94), extension (p = 0.89), and the Flynn´s criteria (p = 0.56) were similar between the groups. The flexion was slightly smaller for the crossed wire group (p = 0.04), but similar to the uninjured side. The Baumann angle was not different between the two fixations (p = 0.79) and the contralateral side (p = 0.1). The lateral humeral capitellar angle was slightly greater for the lateral pinning (p = 0.08), but with no difference with the uninjured elbow (p = 0.62). No iatrogenic injuries were observed.
Conclusion: Both fixations presented similar outcomes that did not significantly affect the carrying angle in relation to the non-fractured side.

: Supracondylar humerus fractures (SCHFs) are the most common pediatric elbow injuries and often require surgical intervention. Despite guidelines, optimal timing for surgical management, particularly for cases without neurovascular compromise, remains unclear. This study evaluates the influence of surgical timing on short-term outcomes, focusing on fracture reduction quality and surgical parameters.

The pulmonary valve (PV), although often less emphasized than other heart valves, is crucial for cardiac function and hemodynamics. Historically, the PV has been underrepresented in echocardiographic assessments due to its rare involvement in pathological conditions, particularly in adults. Additionally, the anatomical position of the PV makes it one of the most challenging valves to visualize using conventional echocardiography.

The ability to characterize periodic nanostructures in the laboratory gains more attention as nanotechnology is widely utilized in a variety of application fields. Scanning-free grazing-emission X-ray fluorescence spectroscopy (GEXRF) is a promising candidate to allow non-destructive, element-sensitive characterization of sample structures down to the nanometer range for process engineering. Adopting a complementary metal-oxide semiconductor (CMOS) detector to work energy-dispersively single-photon detection, the whole range of emission angles of interest can be recorded at once.

In the pursuit of sustainable engineering solutions, material selection is increasingly directed toward resources that offer functional efficacy, economic feasibility, and minimal environmental impact. To replace environmentally damaging materials like aluminum with more sustainable alternatives like wood-based materials, it is essential to improve the durability and longevity of wood. This study explores the potential suitability of modified veneers as an outer protective layer for unmodified wooden load-bearing elements, providing a cost-effective and resource-efficient alternative to bulk modification.

Article Synopsis
- Chronic alcohol-related myopathy (CAM) is a condition that results in muscle weakness and atrophy due to long-term excessive alcohol consumption.
- The mechanisms behind how alcohol causes muscle loss are not fully understood, but this article explores how changes in lipid profiles may play a significant role.
- The authors review existing studies on lipid changes in individuals with CAM and suggest that disrupted lipid regulation could be a key factor in the muscle wasting linked to alcohol use, proposing new directions for research and treatment.
