Summary: This study aimed to objectively assess the elasticity of the pelvic floor during rest and contraction in postmenopausal women using shear wave elastography and electromyography. Results showed higher elasticity in the pelvic floor during active muscle contraction, indicating shear wave elastography as an effective method for objectively assessing pelvic floor muscle strength.

Summary: This study aimed to determine the perioperative characteristics associated with an increased risk of postoperative urinary retention (POUR) following vaginal pelvic floor surgery. Through comparing 18 variables, including age, menopausal status, and intraoperative blood loss, a POUR risk calculator has been developed to help physicians predict the risk of POUR and provide potential management options for patients preoperatively.

Summary: This study examined the self-perception of pelvic floor muscle (PFM) contractions in women receiving repeated verbal instructions during exercise classes, as well as the prevalence and severity of urinary stress incontinence. The results showed that most women were able to correctly contract their PFM, but there was a lack of voluntary contractions during leg movement. However, the instruction group had a higher perception of PFM contraction during knee flexion towards the chest. Women who received instructions to contract their PFM had less severe incontinence compared to the control group.

Summary: This study investigated the effects of extracorporeal magnetic innervation (ExMI) therapy on the bladder neck (BN) and urinary symptoms in women with stress urinary incontinence (SUI). The findings suggest that ExMI therapy is effective for SUI by strengthening the pelvic floor muscle without significantly decreasing BN mobility. The therapy resulted in a significant reduction in urinary frequency and SUI incidence, improved pelvic floor muscle strength, and showed positive effects on female sexual function.

Summary: Vaginal fractional CO2 laser treatment can improve the biomechanical and physiological properties of the vagina, leading to increased vaginal tightening and improved pelvic floor structures. The treatment resulted in significant improvements in female sexual function, vaginal health, and urinary incontinence. Additionally, imaging and histological examinations confirmed the positive effects of the treatment.

Summary: This study systematically reviewed the evidence for increased pelvic floor muscle tone in various pelvic health conditions. The results showed that despite the large number of studies, only a few provided convincing evidence for increased tone/overactivity of pelvic floor muscles in pelvic health conditions. The interpretation of the findings was hampered by design and measurement issues, and terminology was often inaccurate. Few studies explored the effects in male, transgender, and pediatric populations.

Summary: This study investigated pelvic floor changes in primiparas with postpartum stress urinary incontinence (SUI) after vaginal delivery using pelvic floor MRI. The results suggest that increased retrovesicourethral angle, shortened functional urethral length, and the presence of bladder funnel may be important anatomical predictors for SUI in the early postpartum period.

Summary: This study investigated the effect of intravaginal electrical stimulation on the ability of women with involuntary pelvic floor muscles contraction to contract their muscles voluntarily and reduce urinary incontinence. The results showed that after 8 weeks of intervention, the experimental group exhibited significant improvement in pelvic floor muscle contraction ability compared to the control group, as well as a reduction in the severity of urinary incontinence symptoms.

Summary: The study showed that combining PFMT with GT did not significantly improve PFM pressure, urinary incontinence, or perception of improvement compared to PFMT alone in women with mixed urinary incontinence. However, both treatments were effective in relieving symptoms of urinary incontinence.

Summary: Pelvic floor muscle strength and thickness are significantly lower in women with stress urinary incontinence compared to continent women, both antenatally and postnatally. The study showed a positive correlation between the digital assessment and transperineal ultrasound methods in measuring these factors.

Summary: This study examines the association between dietary patterns at 4 years old and cognitive abilities at 10-13 years old, and explores whether adiposity mediates these associations. The results suggest that unhealthy dietary patterns at early age are associated with lower cognitive abilities in children, and this association does not seem to be mediated by adiposity.

Summary: This study developed a new computational model using the Radial Point Interpolation Method to simulate cell proliferation. The experiment found that an integration scheme of 6 x 6 per integration cell and influence-domains with only seven nodes can predict cellular growth and division with the best balance between relative error and computing cost. It was also observed that using irregular meshes does not influence the solution. The results indicate that the algorithm might be a potential tool to study cell proliferation and the Radial Point Interpolation Method is a suitable method for this type of process.

Summary: Tympanosclerosis is an abnormal disorder of the middle ear or eardrum due to recurrent ear infections. A 3D finite element model was developed to simulate different cases of tympanosclerosis, and the magnitude and phase angle of umbo and stapes displacement were obtained. The middle ear sound transfer function was determined for different stimulus levels and frequencies applied to the outer surface of the eardrum. It was found that worse outcomes (hearing loss) occur when the entire ossicular chain is affected by tympanosclerosis.

Summary: This study found that the presence of a tumor can alter the stiffness of the bladder wall, which may affect the progression of bladder cancer. Using atomic force microscopy, the researchers measured the micromechanical properties of the bladder wall layers and observed that tumors promote the development of muscle-like structures in the mucosa.

Summary: An ACL tear, a severe sports injury common among young athletes, is poorly understood, particularly regarding the role of external rotation in the injury mechanism. This study used a finite element model to evaluate knee kinetics and found that combined knee valgus, flexion, tibial external rotation, and high axial load result in higher ACL stress and strain. The study highlights the significance of external rotation and the need for further research in this area. The findings contribute to the prevention, diagnosis, and treatment of ACL injuries.

Summary: Oral maxillofacial rehabilitation of the atrophic maxilla commonly requires vertical and horizontal bone augmentation, with the standard technique being maxillary sinus augmentation. The rupture of the sinus membrane during this procedure increases the risk of contamination. A new bioactive kinetic screw (BKS) bone implant model simplifies and performs autogenous grafting, sinus augmentation, and implant fixation in a single step.

Summary: In this study, the elastic and plastic properties of two TPMS-based cellular structures (gyroid and primitive surface) were analyzed using numerical homogenization. Material laws for the homogenized Young's modulus and yield stress were developed and found to be consistent with experimental data. The developed material laws can be used to optimize functionally graded structures for various applications. A case study on an optimized femoral stem showed that a porous stem made of Ti-6Al-4V can minimize stress shielding while maintaining load-bearing capacity. Additionally, the stiffness of the cementless femoral stem implant with graded gyroid foam was comparable to trabecular bone, with lower maximum stress.
