The Validation of the Japanese Version of the Scoliosis Research Society-30 Questionnaire for Adolescent Idiopathic Scoliosis Patients.

Introduction: The Scoliosis Research Society-30 (SRS-30) is a questionnaire originally developed from the SRS-22r questionnaire and is used to evaluate adolescent idiopathic scoliosis (AIS). It comprised questions on five domains: function, pain, self-image, mental health, and satisfaction, with seven additional questions related to postoperative aspects. In addition to the original English version, translations in multiple languages have been effectively applied.

Retroperitoneal low-grade fibromyxoid sarcoma.

Introduction: Low-grade fibromyxoid sarcoma is an uncommon deep-seated soft-tissue sarcoma that occurs rarely in young adults and children. Although surgical resection provides a long-term prognosis, late local recurrence and metastasis may occur.

Case Presentation: A 44-year-old woman with no prior medical history presented with breathing and abdominal discomfort.

Immune mediators as predictive biomarkers for anti-PD-1 antibody therapy in urothelial carcinoma.

This study aimed to identify immune mediators, including cytokines, chemokines, and growth factors, in the plasma for predicting treatment efficacy and immune-related adverse events (irAEs) in advanced urothelial carcinoma (aUC) treated with immune checkpoint inhibitors (ICIs). We enrolled 57 patients with aUC who were treated with the anti-programmed cell death protein 1 (PD-1) antibody pembrolizumab after the failure of platinum-based chemotherapy between February 2018 and December 2020. Plasma levels of 73 soluble immune mediators were measured before and 6 weeks after initiating pembrolizumab therapy.

Prevalence and the Influence of Trapeziometacarpal Osteoarthritis on Patients with Carpal Tunnel Syndrome.

The coexistence of carpal tunnel syndrome (CTS) and trapeziometacarpal (TMC) osteoarthritis have been previously described. The influence of TMC osteoarthritis in the outcomes of CTS surgery is yet to be elucidated. The purpose of this study is to examine the prevalence of TMC osteoarthritis in patients who underwent open carpal tunnel release (OCTR) and to analyse the influence of osteoarthritis on the postoperative outcomes of CTS.

Association between physical activity and mortality in the Japanese general population with mild to moderate impaired renal function: the Jichi Medical School (JMS) cohort study.

Background: The association between physical activity volume or intensity and mortality in general population with impaired renal function is unclear. We assessed these relationships among Japanese residents with impaired renal function.

Methods: We analyzed 638 individuals with estimated creatinine clearance below 60 ml/min in the Jichi Medical School cohort study.

Frequency of Change in Assessment from Bony Union to Nonunion after Lumbar Interbody Fusion: A Multicenter Study.

Introduction: Assessments of early postoperative bony union after posterior lumbar interbody fusion via computed tomography (CT) have revealed cases in which interbody fixation by bony union resulted in nonfusion due to bone absorption. The apparent bone union state reverted to a nonunion state several months later, exhibiting a so-called "fake union" phenomenon. Additionally, few reports have evaluated the effect of teriparatide on bony union.

Re-Challenging with Nivolumab in Metastatic Renal Cell Carcinoma After Immune-Related Interstitial Pneumonia: A Case Report.

BACKGROUND The efficacy and safety of re-challenge with immune checkpoint inhibitors after immune-related adverse events have not been established. We report a case of successful re-administration of nivolumab in metastatic renal cell carcinoma after discontinuation due to immune-related adverse events. CASE REPORT Laparoscopic nephrectomy was performed on a 52-year-old man diagnosed with renal cell carcinoma pT1bN0M0.

Early detection of anastomotic leakage after esophagectomy using drain amylase levels.

Background: Early diagnosis of anastomotic leakage (AL) after esophagectomy is essential to minimize postoperative complications. In this study, we hypothesized that drain amylase levels may be useful for early AL detection, and measuring drain amylase levels could reduce severe postoperative AL incidence. We, therefore, analyzed the usefulness of measuring drain fluid amylase levels after esophagectomy, in esophageal cancer patients.

Impact of Early Intervertebral Osseous Union After Posterior Lumbar Interbody Fusion on Health-Related Quality of Life.

Study Design: Retrospective cohort study.

Objectives: Nonunion after posterior lumbar interbody fusion (PLIF) is associated with poor improvements in health-related quality of life (HRQOL). We aimed to investigate the influence of early osseous union after PLIF on HRQOL.

Impact of sufficient contact between the autograft and endplate soon after surgery to prevent nonunion at 12 months following posterior lumbar interbody fusion.

Objective: Nonunion after posterior lumbar interbody fusion (PLIF) is associated with poor long-term outcomes in terms of health-related quality of life. Biomechanical factors in the fusion segment may influence spinal fusion rates. There are no reports on the relationship between intervertebral union and the absorption of autografts or vertebral endplates.

Lifetime use of complementary and alternative medicine therapies among community-dwelling older people in Japan.

[Purpose] Three complementary and alternative medicine (CAM) therapies: "Judo therapy", "acupuncture and moxibustion", and "Japanese traditional massage and finger pressure" have been partially covered by the national health insurance in Japan. The lifetime prevalence of the use of these CAM therapies is not well known. The aim of the present study was to report the prevalence of the lifetime use of these CAM therapies.

The Titanium-coated PEEK Cage Maintains Better Bone Fusion With the Endplate Than the PEEK Cage 6 Months After PLIF Surgery: A Multicenter, Prospective, Randomized Study.

Study Design: A multicenter, randomized, open-label, parallel-group trial.

Objective: To investigate interbody bone fusion rates in titanium-coated polyetheretherketone (TiPEEK) and polyetheretherketone (PEEK) cages after posterior lumbar interbody fusion (PLIF) surgery.

Summary Of Background Data: Previous clinical studies have not revealed any significant difference in bone fusion rates between TiPEEK and PEEK cages.

Association between Dietary Intake and Autistic Traits in Japanese Working Adults: Findings from the Eating Habit and Well-Being Study.

"Autistic traits" include a wide range of severity levels. They are often subclinical, and widely distributed in the general population. It is possible that food selectivity due to hyper- or hypo-reactivity to smell or texture, an autistic feature, may result in inadequate nutrient intakes even among non-clinical adults with autistic traits.

Coping behaviors for skeletal muscle injuries and disorders among community-dwelling elderly persons in Japan.

[Purpose] This study aimed to determine the coping behaviors of elderly Japanese community-dwelling persons toward their skeletal muscle injuries and disorders. [Participants and Methods] A mail-in, self-administered questionnaire survey was administered to 1,084 community-dwelling adults aged 70 years and older. Information was obtained regarding their coping behaviors when dealing with bone fractures, dislocations, sprains, bruising, stiff shoulders, low back pain, acute muscle/joint pain, chronic muscle/joint pain, and daily fatigue.

Associations of Overweight, Obesity, and Underweight With High Serum Total Cholesterol Level Over 30 Years Among the Japanese Elderly: NIPPON DATA 80, 90, and 2010.

Background: The trend of association between overweight and high serum total cholesterol (TC) among the elderly is unclear. In addition, there is little evidence of risk of underweight for high TC. Therefore, we examined the trend of association of overweight or underweight with high TC among Japanese elderly people using nationwide population-based data.

Role of Weekly Teriparatide Administration in Osseous Union Enhancement within Six Months After Posterior or Transforaminal Lumbar Interbody Fusion for Osteoporosis-Associated Lumbar Degenerative Disorders: A Multicenter, Prospective Randomized Study.

Background: For elderly patients, posterior lumbar interbody fusion (PLIF) or transforaminal lumbar interbody fusion (TLIF) is usually performed to treat lumbar degenerative diseases. However, some patients exhibit pseudarthrosis following such procedures. The anabolic agent teriparatide is an approved treatment for promoting bone formation in osteoporotic patients.

Orthopedic, ophthalmic, and psychiatric diseases primarily affect activity limitation for Japanese males and females: Based on the Comprehensive Survey of Living Conditions.

Background: Healthy life expectancy (HLE) is used as one of the primary objectives of fundamental health promotion plans and social development plans. Activity limitation is used to calculate HLE, but little study has been done to identify determinants of activity limitation in order to extend HLE. The purpose of this study is to identify diseases and injuries that commonly lead to activity limitation to prioritize countermeasures against activity limitation.
