However, there is currently a lack of literature regarding the biomechanical effectiveness of hip braces. The purpose of this study was to investigate the biomechanical effect of hip braces after hip arthroscopic surgery for FAI.

Delayed cortical bone healing due to impaired nuclear Nrf2 translocation in COPD mice.

The effect of the pathogenesis of chronic obstructive pulmonary disease (COPD) on bone fracture healing is unknown. Oxidative stress has been implicated in the systemic complications of COPD, and decreased activity of Nrf2 signaling, a central component of the in vivo antioxidant mechanism, has been reported. We investigated the process of cortical bone repair in a mouse model of elastase-induced emphysema by creating a drill hole and focusing on Nrf2 and found that the amount of new bone in the drill hole was reduced and bone formation capacity was decreased in the model mice.

The concept of aggressive nutrition therapy and clinical indication: A position paper.

Aggressive nutrition therapy is a nutritional management method that sets energy intake requirements by adding the amount of energy accumulated to energy consumption. It is used to treat patients with undernutrition and sarcopenia. However, evidence for aggressive nutrition therapy is insufficient, and validation through high-quality clinical research is essential.

The prevalence and risk factors of pubic bone marrow edema in femoroacetabular impingement and hip dysplasia.

Femoroacetabular impingement syndrome (FAIS) has been associated with osteitis pubis; however, it is still unclear whether hip dysplasia is associated with osteitis pubis. This study aimed to investigate (i) the incidence of pubic bone marrow edema (BME) on magnetic resonance imaging in symptomatic patients with FAIS, borderline developmental dysplasia of the hip (BDDH) and developmental dysplasia of the hip (DDH) undergoing hip arthroscopic surgery with labral preservation and (ii) the demographic and radiographic factors associated with pubic BME. A total of 259 symptomatic patients undergoing hip arthroscopic surgery between July 2016 and April 2019 were retrospectively reviewed and divided into three groups: FAIS (180 patients), BDDH (29 patients) and DDH (50 patients).

Outcomes and Survivorship at a Median of 8.9 Years Following Hip Arthroscopy in Adolescents with Femoroacetabular Impingement: A Matched Comparative Study with Adults.

Background: Because of the unique theoretical surgical risks, including osteonecrosis, acute iatrogenic slipped capital femoral epiphysis, and epiphyseal injury, the optimal treatment strategy for femoroacetabular impingement (FAI) in growing adolescents has yet to be established. The aim of this study was to compare the clinical outcomes of primary arthroscopic treatment of FAI in growing adolescents with a matched adult group.

Methods: Patients with FAI who underwent arthroscopic treatment with a minimum follow-up of 2 years were included.

Prognostic Value of the Three-Dimensional Right Ventricular Ejection Fraction in Patients With Asymptomatic Aortic Stenosis.

The right ventricular (RV) function is an important prognostic marker of asymptomatic aortic stenosis (AS). However, previous publications have not addressed the additive value of conventional RV parameters over left heart parameters. Whether three-dimensional echocardiography (3DE)-derived RV ejection fraction (RVEF) has prognostic utility independent of 3DE derived left heart parameters is also unknown.

[Accuracy of VSRAD Analysis Using Scout Images: Comparison with Conventional 3D-TWI].

The voxel-based specific regional analysis system for Alzheimer's disease (VSRAD), which targets volume loss in medial temporal lobe, was developed as a sensitive diagnostic tool to detect early stages of Alzheimer's disease. However, conventional three-dimensional T -weighted image (3D-TWI) for VSRAD analysis acquires relatively long acquisition time. Recently, it became possible to acquire Scout images (Scout) for positioning as a 3D image in a short time.

Cotyloid Fossa Coverage Percentages May Be Associated With Alpha Angle, Labral Tear, and Clinical Outcomes in Patients With Femoroacetabular Impingement.

Background: Within the hip joint, the anatomy of the acetabulum and cotyloid fossa is well established. There is little literature describing the association between the size of the cotyloid fossa relative to the acetabulum and characteristics of patients with femoroacetabular impingement (FAI).

Purpose/hypothesis: The purpose was to calculate the cotyloid fossa coverage percentage in the acetabulum and determine its association with patient characteristics, radiographic parameters, intra-articular findings, and preoperative patient-reported outcomes in patients with FAI.

Introduction And Hypothesis: To compare the perioperative costs analysis between laparoscopic/transvaginal and the mesh/non-mesh surgeries for pelvic organ prolapse (POP) in Japan.

Materials And Methods: From April 2013 to April 2017, 890 patients who underwent POP surgeries were enrolled in this study. Regarding transvaginal native tissue repair (TV-NTR: transvaginal hysterectomy with colpocleisis), transvaginal mesh surgery (TVM), laparoscopic native tissue repair (L-NTR: laparoscopic hysterectomy and uterosacral ligament colposuspension), and laparoscopic sacrocolpopexy (LSC), a retrospective observational study was performed.

Editorial Commentary: Mesenchymal Stem Cell Preparation Methods Affect the Properties of Shoulder Subacromial Bursa-Derived Cells.

Augmentation of mesenchymal stem cells (MSCs) from the subacromial bursa in the setting of irreparable rotator cuff tears is a powerful candidate for future regenerative medicine. However, little is known about whether the preparation technique affects the individual differences and potentials of subacromial bursa-derived MSCs. The yields obtained by chopping or cell-expansion techniques with a high-density of initial nucleated cells seem to be lower than those obtained with low-density cell-expansion techniques.

Changes of intravaginal microbiota and inflammation after self-replacement ring pessary therapy compared to continuous ring pessary usage for pelvic organ prolapse.

Aim: Continuous usage of a ring pessary for pelvic organ prolapse may cause a disturbance of intravaginal microbiota and intravaginal mucosal damage. To avoid the side effects of continuous ring pessary therapy, daily self-replacement of the ring pessary is recommended. The purpose of this study is to evaluate the outcomes of self-replacement versus continuous ring usage, by analysing clinical findings and intravaginal microbiota.

Lanthanum Deposition in the Gastroduodenal Mucosa of Dialysis Patients.

Lanthanum (La) carbonate (LC) is one of the most popular phosphate binders used in dialysis patients with end-stage renal disease. Only a small amount of LC is believed to be absorbed from the gastrointestinal (GI) tract because LC strongly binds to dietary phosphate and forms insoluble complexes. La deposition in the gastroduodenal mucosa has been recently identified.

Editorial Commentary: Are We Ready to Apply Stem Cell Therapy in Rotator Cuff Tear Surgery?

For rotator cuff tear surgery, application of mesenchymal stem cells (MSCs) is a promising new option. Among various MSC sources, synovial tissue contains a high number of MSCs with high chondrogenic potential. Because chondrogenic formation is an important factor in enthesis healing in rotator cuff repair, synovial MSCs derived from the subacromial bursa are superior candidates for the augmentation of rotator cuff tear surgery.
