Summary: This study aimed to investigate the association between recent fragility fractures and 8-year risks of revision THA, periprosthetic fracture, and secondary fragility fracture. The study found that patients with recent fragility fractures within 3 years prior to THA had significantly increased risks of revision THA, periprosthetic fracture, and secondary fragility fracture.

Summary: This study aimed to investigate the association of hip bone mineral density with mortality risk after hip fracture. The results showed that all hip bone densities were significantly associated with mortality risks, and hip trochanter bone mineral density showed the strongest correlation.

Summary: This study analyzed differences in 3D DXA parameters at the hip site among patients with acromegaly or AGHD and healthy controls. The study found cortical bone impairment in AGHD patients and highlighted the trochanter as the site with greater cortical bone differences between acromegaly patients and controls. 3D-DXA provided useful information about bone involvement in GH-related disorders, with AGHD patients showing distinct involvement of the cortical structure.

Summary: This study compared lumbar volumetric bone mineral density (vBMD) assessed by a convolutional neural network (CNN)-based framework in routine CT to vBMD from dedicated quantitative CT (QCT). The study found that automated opportunistic osteoporosis screening in routine CT of various scanner setups is feasible and may demonstrate high diagnostic accuracy for prevalent vertebral fractures (VFs).

Summary: Vertebral fractures (VFx) are common in older adults, especially at the mid-thoracic and thoracolumbar regions of the spine. This study aimed to determine activities that cause the largest vertebral load-to-strength ratios (LSRs) and examine patterns of LSRs along the spine for high-load activities in a sample of adult men and women. The results highlight the importance of considering a variety of activities when evaluating vertebral LSRs and provide guidance for future studies on the biomechanics of VFx.

Summary: This study evaluated the prevalence of vertebral fractures (VF) among middle-aged and elderly Chinese men and women, and compared the lumbar spine volumetric bone mineral density (vBMD) between those with a grade 1 vertebral fracture and non-fractured individuals. The study found that the prevalence of VF increased rapidly in women after the age of 50, while it grew more slowly in men. Participants with a grade 1 VF had lower vBMD compared to non-fractured individuals, except for men under the age of 50.

Summary: The study indicates that changes in total body lean mass and fat mass during adolescence are associated with bone outcomes. Total body lean mass has a greater influence on bone development than total body fat mass, with lean mass being the predominant predictor of bone outcomes.

Summary: Maintenance of vigorous exercise habits from young to old age is considered protective against hip fractures. This study found that continuing high-intensity exercise in old age is associated with a lower hazard rate of hip fractures, although this protective effect diminishes with age.

Summary: This study examined the long-term survival and incidence of secondary fractures after fragility hip fractures. The 5-year survival rate was 62%, with higher mortality risk in patients with GNRI < 92. The 5-year incidence of secondary fractures was 22%, which was significantly higher in patients with a BMI < 20.

Summary: This study investigated the relationship between BMD and risk of fragility fracture in native Chinese population. The findings showed that decreasing BMD measurement parameters and anthropometric indicators increased the risk of clinical fragility fracture, with variations in fracture HR based on gender and site.

Summary: This study aimed to identify risk factors for hip fractures in elderly Korean patients, especially in patients with osteoporosis. The retrospective analysis of 168 patients showed that lower body weight, BMI, and BMD Z-scores were associated with a higher incidence of intertrochanteric fractures compared to femoral neck fractures. This suggests that there is a correlation between low body weight, BMI, and BMD Z-scores and an increased risk of intertrochanteric fractures in elderly Korean patients.

Summary: Past research suggests that men are more likely to smoke and have a higher risk of smoking-related conditions than women. A meta-analysis was conducted to assess the association between smoking and fracture risk in men. The analysis found a significant increase in fracture risk associated with smoking in men. This highlights the importance of smoking cessation in reducing the risk of fractures in male smokers.

Summary: Fragility fractures are a significant public health issue globally, with hip fractures being most prevalent in women aged 80 and above. Older age and recent fractures were identified as independent risk factors for further fracture events. There was a significant excess mortality rate in individuals aged 80 and above with a previous hip fracture.

Summary: This study evaluated the image quality of different reconstruction methods in unenhanced PCCTs of the head. The results showed that the polyenergetic reconstruction was superior to virtual monoenergetic reconstructions in terms of signal-to-noise ratio and contrast-to-noise ratio. Although certain virtual monoenergetic reconstructions performed better in terms of artifacts, there is still room for improvement. This study is important for further improving the image quality of PCCT.

Summary: The study evaluated the diagnostic accuracy of virtual non-contrast images acquired with the first clinical photon counting CT scanner for the assessment of hepatic steatosis. The results showed that the spectral datasets from the PCCT scanner allowed reliable reconstruction of VNC images for accurate evaluation of hepatic steatosis. Adjusting the cut-off values improved the performance of the CT indices, offering excellent sensitivity and specificity.

Summary: Radical esophagectomy with lymphadenectomy is the primary treatment for advanced esophagus carcinoma. Advances in surgical techniques, such as minimally invasive and robotic oesophagectomy, have improved the outcomes in the last two decades. Perioperative management, including prehabilitation, PDK application, early mobilization, and early food intake, also contribute to reducing complications. Early detection and interdisciplinary management are key to increasing the safety of esophageal surgery.

Summary: This study reports the initial clinical experience with NHCA as a liquid embolic agent for neurovascular embolization. The results show that NHCA is feasible and effective, particularly for small and tortuous vessels that require low-profile catheterization and a slow and controlled polymerization. Further studies are needed to prove the benefits of NHCA over established embolic agents.

Summary: This study aimed to compare a novel contrast-free and triggering-free vascular imaging technique (REACT) with CE-MRA in the detection of carotid artery stenosis and plaques, as well as image quality, in stroke patients. The results showed that REACT had comparable sensitivity and specificity to CE-MRA in detecting stenosis and plaques, and yielded similar image quality.

Summary: This study found that in endovascular therapy for large ischemic strokes, mTICI 3 did not improve functional outcomes at 90 days compared with mTICI 2b. The study suggests that the additional maneuvers to seek for mTICI 3 in large ischemic strokes might not be warranted based on the benefit/risk ratio.
