Summary: This study conducted plane strain tests on coarse frozen sand under different temperatures and loading conditions, analyzing the strain localization characteristics with PIV technique. The results show that temperature and strain rate have little influence on shear band formation, and X shape shear bands are more likely to be generated at lower strain rates. Additionally, most of the strain field is in a dilatancy state at failure, and the shear band inclination angle and width are inversely proportional to temperature.

Summary: This study aimed to determine the thickness and stiffness of the iliotibial band (ITB) in patients with knee osteoarthritis (KOA) and to identify the gait parameters that are associated with ITB properties. The results showed that patients with KOA had higher shear wave velocity, indicating greater stiffness of the ITB, compared to asymptomatic adults. The knee adduction moment and hip flexion moment were associated with the shear wave velocity, while no parameters were associated with the thickness. This suggests that KOA patients have a stiffer ITB, which is related to greater knee adduction and hip flexion moments during walking.

Summary: This study used shear wave elastography to evaluate the stiffness of muscles in patients with iliotibial band syndrome. The results showed significant differences in the stiffness of the lateral thigh muscles in patients compared to healthy controls, indicating a potentially larger role of hip abductor muscles in the pathophysiology of ITBS.

Summary: There is currently inconclusive evidence regarding sex-related differences in muscle force and torque control. This study investigated sex differences in knee extensor muscle torque control using different measures of magnitude and complexity. The findings showed that males had higher absolute magnitude of torque fluctuations compared to females, but there were no sex differences when fluctuations were normalized to mean torque output. Additionally, males had lower complexity and higher fluctuation analysis, indicating sex differences in muscle torque control strategies. These results suggest the importance of considering both magnitude and complexity when examining sex differences in muscle force control.

Summary: High strain rate compression of Ti-60 titanium alloy with equiaxed structure was studied using split-Hopkinson pressure bar technique. The results showed that increasing temperature led to a decrease in flow stress and yield stress for Ti60 alloy, with the formation of adiabatic shear bands and recrystallization grains.

Summary: In this study, the evolution of shear bands in Cu50Zr50 metallic glasses under different strain rates was investigated using molecular dynamics simulation. The results showed that the synchronized evolutions of microstructure, deformation, and mechanical properties were less affected by loading conditions or strain rates. However, an increase in strain rate resulted in a noticeable retardation of the initiation and propagation of the dominate shear band, leading to a change in the fracture mode of the metallic glasses.

Summary: The aim of this systematic review is to determine the current evidence on sex differences in the association between risk factors and knee osteoarthritis (KOA) and their prevalence. The results showed that women are associated with high BMI, alcohol consumption, atherosclerosis, and high vitamin E levels, while men are associated with high physical activity, soft drink consumption, and abdominal obesity. Knee injury, high blood pressure, and low step rate seem to affect both women and men. However, more high-quality studies are needed to assess the impact of sex differences on risk factors for KOA, especially for symptomatic/clinical OA.

Summary: The objective of this study was to investigate the sex differences in late gadolinium enhancement (LGE) in patients with acute myocarditis (AM) using cardiovascular magnetic resonance (CMR). A retrospective study was conducted on 135 consecutive patients with AM who met the Lake Louise criteria. The results showed that women were more likely to present with dyspnea, higher prevalence of septal LGE, and increased global circumferential strain parameters compared to men. Multivariate analysis revealed that female sex remained an independent determinant of septal LGE. These findings highlight the sex-based differences in cardiovascular diseases.

Summary: Despite increasing interest and calls to action for studying sex differences in cardiovascular disease, only a small fraction of publications in the past decade have addressed this issue. There was no significant growth in the proportion of sex-specific publications over a recent 10-year period, except for general research articles.

Summary: This study compared the iliotibial tract thickness between individuals with patellofemoral pain (PFP) and asymptomatic individuals, and analyzed the correlation between iliotibial tract thickness and self-reported pain and function. The study found that women with PFP had greater iliotibial tract thickness compared to asymptomatic women, but there was no association between iliotibial tract thickness and subjective measures of pain and function.

Summary: Research shows that individuals in same-sex marriages who give birth have similar perinatal outcomes to those in different-sex marriages, but the use of assisted reproductive technologies can affect these outcomes. More studies are needed to understand why the use of assisted reproductive technology does not pose a risk for poor birth outcomes in same-sex marriages.

Summary: The study aimed to determine the shear wave velocity of the iliotibial band (ITB) in different tasks and regions, showing higher SWV during contraction and Ober test, and in the middle region during standing and pelvic drop. A tendency of decreased SWV was observed after running. The reliability was moderate-to-good in the middle region for standing tasks.

Summary: This scoping review summarized tasks, outcome measures, and inclusion criteria commonly used in RCTs assessing sensorimotor function following ankle sprain and CAI. It found that single-limb stance was the most common task, posterior-medial reach distance of the SEBT was the most common outcome measure, and different inclusion criteria were used. The wide range of assessments and criteria used could complicate comparisons and generalizations of study results.

Summary: There is a lack of standardized concussion education for collegiate athletes in Japan, leading to variations in guidelines by sport. This study aimed to assess the knowledge and attitudes toward concussion among Japanese male collegiate athletes and their experiences with suspected concussion symptoms. The findings revealed that a significant number of athletes had experienced symptoms of suspected concussion, but many did not report these symptoms. Recognition of concussion symptoms was lower for some symptoms compared to previous studies, suggesting that educational initiatives are important to improve athletes' understanding and reporting behavior.
