Summary: This case report described the occurrence of periprosthetic femoral fractures after hip arthroplasty in a 54-year-old female patient. The patient underwent revision surgery using the Solution prosthesis, but later experienced a mid-femoral prosthesis fracture. A second revision surgery and allogeneic bone plate fixation were performed, resulting in satisfactory outcomes.

Summary: Hip arthroplasty is a common procedure, but some patients experience persistent pain after the surgery. The complications depend on various factors such as post-operative delay, material type, patient characteristics, and surgical approach. Radiographs, CT, and MRI are commonly used imaging modalities for diagnosis, but there is still no consensus on the optimal imaging workup for complications.

Summary: The study developed novel algorithms to simulate the cumulative process of local slippage based on modified Iwan models, confirming the reliability of previous theoretical analytical results. The mechanism of local slippage accumulation was revealed and critical local slippage accumulation was studied. The proposed novel thread structures showed superior anti-loosening performance compared to existing products, and were easy to install and remove.

Summary: The study compared the remodeling process after femoral revisions for proximal femoral periprosthetic fractures (PFF) and femoral aseptic loosening (AL), finding that proximal femoral bone stock reconstitutes much quicker around PFF. The Global Radiological Score (GRxS) measurements on plain radiographs showed good reproducibility for everyday use in a revision arthroplasty practice.

Summary: This study evaluated the impact of susceptibility artifacts from hip prostheses on cancer detection rate (CDR) in prostate MRI. The results showed that moderate to severe artifacts led to a decrease in CDR by 74%. This is clinically significant and may require expanding the indications for biopsy.

Summary: The study aimed to assess the associations of physical activity (PA) volume, PA intensity distribution, and moderate-to-vigorous PA (MVPA) with bone mineral content, lean mass, and fat mass in children. The results showed that PA volume was positively associated with bone mineral content in both females and males, and positively associated with lean mass (males) or negatively associated with fat mass (males). PA intensity was negatively associated with bone mineral content in males. MVPA was positively associated with lean mass and negatively associated with fat mass in both females and males.

Summary: This study analyzed accelerometer data from individuals aged 17 to 23 to assess the associations between accelerometer metrics and bone outcomes at age 23. The results showed that shorter epoch lengths (1-5 seconds) were more appropriate for assessing the associations between accelerometer metrics and bone outcomes. Acceleration was positively associated with bone density in males, while intensity was important for bone outcomes in both sexes.

Summary: This study examined the association between self-reported walking pace and all-cause mortality (ACM), and found that the association persisted across different categories of accelerometer-assessed physical activity status. The results showed that a higher walking pace was associated with higher physical activity levels and lower risk of all-cause mortality. The findings highlight the importance of both self-reported walking pace and accelerometer-assessed physical activity in predicting mortality risk.

Summary: This study aimed to compare raw triaxial acceleration data from two accelerometer brands (GENEActiv and ActiGraph GT3X+), as well as different placement positions (non-dominant wrist, dominant wrist, and waist). Thresholds for differentiating inactivity, moderate intensity, and vigorous intensity were derived. The results showed that the acceleration increases with the intensity of activities, regardless of brand or placement. The thresholds obtained from this study can be used to classify movement behaviors in adults accurately.

Summary: High physical activity levels during wake are beneficial for health, while high movement levels during sleep are detrimental to health. The associations of accelerometer-assessed physical activity and sleep disruption with adiposity and fitness were compared using standardized and individualized wake and sleep windows. The results showed that average acceleration and intensity distribution during the wake window were beneficially associated with adiposity and fitness, while average acceleration during the sleep window was detrimentally associated with adiposity and fitness. The standardized wake and sleep windows may have stronger associations with health.

Summary: The aim of this study was to compare the differences in device-measured physical activity (PA) behaviors and physical function (PF) in patients with type 2 diabetes mellitus (T2DM) with and without peripheral artery disease (PAD). The results showed that T2DM patients with PAD had lower levels of physical activity and poorer physical function. These differences persisted even after controlling for confounding factors.

Summary: This study examined the associations between physical activity measured by thigh-worn and wrist-worn accelerometers and cardiometabolic health. The results showed that both thigh-worn and wrist-worn accelerometers were associated with cardiometabolic risk and individual health markers. However, only the wrist-worn accelerometer captured aspects of intensity distribution related to cardiometabolic health.
