Introduction
Androgen deprivation therapy (ADT) is widely used for the treatment of prostate cancer. ADT is associated with reduced bone density leading to an increased risk of osteoporotic fracture. ...The objective of this retrospective cohort study was to quantify fracture risk in men treated with ADT for prostate cancer in real-world practice in Japan.
Materials and methods
Data were extracted from the Japanese Medical Data Vision (MDV) database. Men initiating ADT for treatment of prostate cancer between April 2010 and March 2021 were identified and matched to a cohort of prostate cancer patients not taking ADT using a propensity score. Fracture rates were estimated by a cumulative incidence function and compared between cohorts using a Cox cause-specific hazard model. Information was extracted on demographics, comorbidities and bone densitometry.
Results
30,561 men with PC starting ADT were matched to 30,561 men with prostate cancer not treated with ADT. Following ADT initiation, <5% of men underwent bone densitometry. Prescription of ADT was associated with an increased fracture risk compared to not taking ADT (adjusted hazard ratio: 1.63 95% CI 1.52–1.75).
Conclusion
ADT is associated with a 1.6-fold increase in the risk of osteoporotic fracture in men with prostate cancer. Densitometry in this population is infrequent and monitoring urgently needs to be improved in order to implement effective fracture prevention.

Aim
Patients with hip fractures have a high rate of mortality or decreased mobility, despite early operative treatment and rehabilitation. The first aim of this study was to investigate the factors ...of decreased walking ability after hip fracture based on whether walking ability was or was not maintained postoperatively. The second aim was to examine the usefulness of the Comprehensive Geriatric Assessment 7 (CGA7), modified from the conventional Comprehensive Geriatric Assessment, for predicting postoperative walking ability.
Methods
This study included patients who were treated surgically for hip fractures. We divided patients by whether they did or did not maintain their walking ability postoperatively. We registered the following demographic data: walking ability preadmission and at discharge, CGA7 score, cognitive impairment, the patient's prefracture status, fracture type, surgical waiting time, hospital stay duration, limitation of weight‐bearing, postoperative complications, transfer to rehabilitation hospital, final living place, and follow‐up period. The characteristics of the two groups were compared using Wilcoxon's rank‐sum test, the chi‐squared test, or Fisher's exact test.
Results
Among 855 patients, 616 (73.0%) patients maintained walking ability and 239 (27.0%) patients did not. Multivariate logistic regression revealed that the factors of age, sex, preoperative walking ability, and postoperative complications were significantly associated with maintaining postoperative walking ability. Furthermore, the higher the CGA7 score, the more likely were patients to maintain their walking ability (odds ratio, 0.72; 95% confidence interval, 0.61–0.85;
P
< 0.001).
Conclusions
Patients who had a low CGA7 score had the potential risk of decreased walking ability.

To evaluate the efficacy of denosumab for progressive bone erosion in risk factor subgroups of Japanese RA patients.
This study included 340 RA patients on MTX from the dose-response study of ...Denosumab in patients with RheumatoId arthritis on methotrexate to Validate inhibitory effect on bone Erosion (DRIVE study-a 12-month, multicentre, randomized, double-blind, placebo-controlled, phase II study). The patients were randomized to receive placebo or denosumab 60 mg every 6 months, 3 months or 2 months. Subgroup analyses involved baseline RF, ACPA, swollen joint count, CRP level, RA duration, ESR and glucocorticoid use.
Patients with risk factor positivity generally showed consistent results for the primary endpoint of the change in the modified Sharp erosion score at 12 months from baseline. In the placebo, every 6 months, every 3 months and every 2 months groups, the mean changes in the erosion score, according to the RF status (RF-positive vs -negative subgroups), were 1.18 vs 0.59, 0.25 (P = 0.0601 vs placebo) vs 0.31 (P = 0.0827), 0.21 (P = 0.0422) vs -0.02 (P = 0.0631) and 0.15 (P = 0.0010) vs -0.05 (P = 0.0332), respectively, while the mean changes in the erosion score, according to the ACPA status (ACPA-positive vs -negative subgroups), were 1.30 vs 0.07, 0.26 (P = 0.0142) vs 0.33 (P = 0.2748), 0.16 (P = 0.0058) vs 0.08 (P = 0.7166) and 0.09 (P < 0.0001) vs 0.08 (P = 0.8939), respectively.
Denosumab is a potentially useful treatment option for RA patients who are positive for RF, ACPA and other possible risk factors.

Excessive elbow valgus stress can often cause pitching elbow injuries, and rehabilitation is usually required before an athlete can resume playing. However, there is a lack of information on the ...partial load rehabilitation of pitching elbow injuries caused by valgus extension overload based on elbow valgus stress. The purpose of this study was to clarify how quantitative partial elbow valgus stress while pitching affects ball velocity and subjective pitch-effort.
Forty-six male baseball pitchers participated in this study. Each player wore a wearable device on the elbow that collected their pitch parameters. Ball velocity was measured using a radar gun. Each elbow valgus stress was measured while each player was instructed to throw 5 fastballs at full effort. Then, based on the average stress of the 5 throws (100% partial valgus stress), the 75% and 50% stresses were calculated (75% and 50% partial valgus stress, respectively). Each pitcher continued to pitch until the number of pitches thrown at the targeted elbow stress reached 5. Each player was asked about their subjective pitch-effort after completing each type of partial valgus stress pitch. Outcomes were statistically evaluated using either a 1-way repeated measures analysis of variance or 2-way analysis of variance.
The ball velocity was 72% (95% confidence interval CI, 69%-75%) and 58% (95% CI, 55%-61%) during the 75% and 50% partial valgus stress, respectively (P < .001). Subjective pitch-effort was 41% (95% CI, 38%-44%) and 19% (95% CI, 16%-22%) while pitching at 75% and 50% partial valgus stress, respectively (P < .001).
It may be desirable to instruct pitchers to throw at less than 20% subjective pitch-effort of the max if they want to pitch at 50% partial valgus stress. Elbow valgus stress might correlate with ball velocity at 75% partial valgus stress pitch. These results could enable clinicians and coaches to perform safer return-to-throwing programs and prevent excessive load on the elbow.

Cerebral venous thrombosis (CVT) is a cerebrovascular disorder that causes venous infarction and intracerebral hemorrhage (ICH) with occlusion of cerebral veins, and its incidence is estimated to be ...5 per 1 million people per year, accounting for 0.5% to 1.0% of all strokes. Despite advances in the recognition of CVT, the diagnosis and treatment may be difficult because of the diversity of underlying risk factors. A rare case of ICH due to CVT during surgery is described.
A 69-year-old-man presented to our department with a history of paralyzed extremities after a backward fall and head trauma. The patient had a history of pharyngeal cancer treated with neck dissection and radiotherapy. Computed tomography (CT) images showed continuous ossification of the posterior longitudinal ligament (OPLL) at C2-5 levels and a fracture line at the caudal end plate of the C5 body. The diagnosis was traumatic cervical cord injury, so that posterior cervical decompression and fusion was performed. Immediately after surgery, the patient developed an epileptic seizure and the disturbance of consciousness persisted. MR venography and contrast CT images showed absence of flow from the superior sagittal sinus to the transverse sinus.
The diagnosis in this case was ICH due to CVT.
The patient was treated with anticoagulation using unfractionated heparin.
The patient ultimately made a complete recovery from CVT.
Although risk factors for CVT are diverse, head and neck injury, patient's position during surgery, and postoperative radical neck dissection for pharyngeal cancer might have been the factors in this case. While the measures to prevent this disease are uncertain, early diagnosis and treatment are needed to avoid serious complications.
Atypical ulnar fracture (AUF) is a rare condition that may occur in patients treated with bisphosphonates. We describe the clinical course of a patient who had an AUF during treatment with denosumab. ...An 86-year-old woman treated with denosumab for 5 years experienced a complete transverse fracture of the proximal left ulna after falling from a standing height. Intraoperative photographs showed cortical thickening around the fracture site. Therefore, we diagnosed the patient with AUF and performed internal fixation with a locking plate. However, a re-fracture occurred 2.5 months after surgery, which was treated with locking plate replacement with a longer one with a bone graft. One year after the second surgery, the fracture healed. To our knowledge, this is the second case report of an AUF occurring during denosumab treatment. Our case highlights the importance of careful follow-up of patients receiving not only bisphosphonate, but also denosumab.

Introduction
There are approximately 13 million patients with osteoporosis in Japan; however, only 20% of them receive treatment. This study compared the 4‐year continuation rates of osteoporosis ...drugs at different dosing intervals across throughout Japan.
Materials and methods
Receipt data were analyzed to determine the continuation of osteoporosis medication in patients who began treatment at 210 hospitals throughout Japan between October 2016 and September 2017. Continuation rates were compared using Kaplan–Meier curves and log‐rank tests.
Results
The 4‐year continuation rates of daily, weekly, monthly, semi‐annual, and yearly medications nationwide were 8.6%, 16.5%, 13.5%, 31.0%, and 26.0%, respectively. The 4‐year continuation rates for semi‐annual and yearly drugs were significantly higher than daily, weekly, monthly drugs.
Conclusion
Throughout Japan, the 4‐year treatment continuation rates of daily, weekly, monthly, semi‐annual, and yearly osteoporosis drugs all decreased over time. However, the continuation rates of semi‐annual and yearly drugs in the fourth year were significantly higher than those for the other dosing regimens. Therefore, injectable drugs with dosing intervals ≥6 months may improve continuation rates of osteoporosis drugs. Geriatr Gerontol Int 2023; 23: 665–670.
In various regions of Japan, the 4‐year treatment continuation rates of daily, weekly, monthly, semi‐annual, and yearly drugs of osteoporosis drugs with different dosing intervals decreased over time. However, the continuation rates of semi‐annual and yearly drugs in the fourth year were significantly higher than those of the other drugs.

Aim
In 2022, the Japanese Orthopaedic Association developed “Locomo Age,” which can be used to measure mobility. The potential effects of measuring Locomo Age on motivation to exercise are yet to be ...explored. This study aimed to determine whether the measurement of Locomo Age improved motivation for exercise.
Methods
In total, 90 fitness club users (17 men and 73 women) were enrolled in the study. The participants performed the locomotive syndrome risk test. These results were entered on a smartphone website, and their Locomo Age was automatically calculated. Questionnaires about impressions of Locomo Age and changes in motivation for exercise after measuring Locomo Age were surveyed.
Results
The mean Locomo Age of the participants was 84.4 ± 8.5 years, which was significantly higher than their actual age (75.9 ± 7.2 years, P < 0.001). Questionnaires showed that 55 participants (61.1%) felt that their Locomo Age was higher than expected; 42 participants (46.7%) had increased motivation for exercise, and only two participants (2.2%) had decreased motivation. The rate of improvement in motivation for exercise was higher in the group of participants who reported having an older Locomo Age than they expected compared with that of the group with a Locomo Age that was the same as they expected (P < 0.05).
Conclusions
The measurement of Locomo Age improved the motivation for exercise. This result remained true even when the Locomo Age was higher than expected, as it did not decrease the participants' motivation. Locomo Age allows for the comprehension of participants' mobility without medical knowledge. Geriatr Gerontol Int 2023; 23: 589–594.
The measurement of Locomo Age improved motivation for exercise in fitness club users. This result remained true even if Locomo Age was higher than expected.
