Deep venous thrombosis (DVT) has insidious clinical symptoms, and only a few patients suffer from lower limb swelling, tenderness and dorsal flexion pain. We aimed to explore the ultrasonographic features and risk factors of postoperative lower limb DVT in patients with lower limb fractures. Ninety patients with lower limb fractures admitted from January 1st, 2021 to June 30th, 2023 were selected. Color Doppler ultrasonography was performed one month after operation, and the ultrasonographic features were recorded. DVT was diagnosed according to the results of venography, based on which the patients were divided into a DVT group and a non-DVT group. Their basic and treatment-related data were compared. The risk factors for postoperative DVT were screened by multivariate logistic regression analysis. A total of 63 cases were diagnosed with DVT by venography, with a detection rate of 70.00%. A total of 69 cases were diagnosed with DVT by ultrasonography, with a detection rate of 76.67% (P>0.05). The concurrent internal medicine diseases, associated injuries, no preventive measures for thrombosis, operation time ≥2 h, no active or passive exercise after operation, pelvic and proximal femoral fractures, knee fractures and tibiofibular fractures were risk factors for postoperative DVT in patients with lower limb fractures (P<0.05). Ultrasonography is effective for diagnosing postoperative lower limb DVT in patients with lower limb fractures. Related preventive measures should be taken promptly to control the risk factors.

Stair-descent phenotypes in community-dwelling older adults determined using high-level balance tasks.

Background: Falls on stairs are a major cause of severe injuries among older adults, with stair descent posing significantly greater risks than ascent. Variations in stair descent phenotypes may reflect differences in physical function and biomechanical stability, and their identification may prevent falls.
Aims: This study aims to classify stair descent phenotypes in older adults and investigate the biomechanical and physical functional differences between these phenotypes using hierarchical cluster analysis.

Tumor necrosis factor-α (TNF-α) induces a multitude of actions and consequences in bone and cartilage resorption and immune response augmentation. In this research, we aimed to investigate the effects of TNF-α on osteogenesis parameters in newborn mice. Experimental research was conducted on 42 pregnant mice, dividing into seven groups as follows: control (no injection), vehicle 1 (PBS injection on 7-9th pregnancy days (PD)), vehicle 2 (PBS injection during pregnancy), experimental 1 (injection of 10 ng/kg of TNF-α on 7-9th PD), experimental 2 (injection of 100 ng/kg of TNF-α on 7-9th PD), experimental 3 (injection of 10 ng/kg of TNF-α during pregnancy) and experimental 4 (injection of 100 ng/kg of TNF-α during pregnancy).

The present study aims to examine the effect of 4 h of continuous sitting on cerebral endothelial function, which is a crucial component of cerebral blood flow regulation. We hypothesized that 4 h of sitting may impair cerebral endothelial function similarly to how it affects lower limb vasculature. Thirteen young, healthy participants were instructed to remain seated for 4 h without moving their lower limbs.

The maintenance of an appropriate ratio of body fat to muscle mass is essential for the preservation of health and performance, as excessive body fat is associated with an increased risk of various diseases. Accurate body composition assessment requires precise segmentation of structures. In this study we developed a novel automatic machine learning approach for volumetric segmentation and quantitative assessment of MRI volumes and investigated the efficacy of using a machine learning algorithm to assess muscle, subcutaneous adipose tissue (SAT), and bone volume of the thigh before and after a strength training.

Background: Krabbe disease (KD; globoid cell leucodystrophy) is a rare autosomal recessive lipid storage disorder that affects the white matter of the peripheral and central nervous. Late-onset KD is less frequently diagnosed and often presents with milder symptoms, making accurate diagnosis challenging, especially when distinguishing it from peripheral neuropathy. In this report, we present two cases of late-onset KD in a Chinese family.
