Purpose:
Romosozumab reportedly increases bone density in patients with severe osteoporosis; however, data on its clinical effects are limited. We conducted a multicenter retrospective survey to study the bone density-increasing effects of romosozumab and blood test-based predictive factors in patients with severe osteoporosis, examining its effects in clinical practice.
Materials and Methods:
This was a multicenter retrospective observational study. The subjects were patients with severe osteoporosis who were treated with romosozumab at the participating facilities. The increase in bone density was assessed by comparing bone density changes (as a percentage) in the lumbar spine, femoral neck, and total femur before and 12 months after administration using dual-energy X-ray absorptiometry. The association between changes in bone density at each site and pre-treatment bone metabolism markers (Tracp 5b, P1NP), serum calcium levels, nutritional status [Conut score: albumin, total cholesterol (TCho), and total lymphocyte count], and kidney function (eGFR) was assessed.
Results:
In both naïve patients and those switching from bone resorption inhibitors, the bone density increased significantly. In naïve patients, eGFR were positively associated with bone density in the total femur. In cases of switching from bone resorption inhibitors, correlations were found between Tracp 5b and lumbar spine bone mineral density (BMD), as well as between Tracp 5b, Alb, T-Cho, and eGFR in the total femur BMD.
Conclusion
Romosozumab administration significantly increases bone density in osteoporosis, and assessing key predictive factors is necessary to ensure clinical effectiveness.

An 82-year-old male patient who had a history of ischemic heart disease (IHD) and Debranching Thoracic Endovascular Aortic Repair (TEVAR) (right axillary artery-left axillary artery-left common carotid artery) was admitted to our hospital due to sudden chest pain. The diagnosis revealed acute coronary syndrome: 2-vessel lesions, including the left main trunk (LMT) (right coronary artery (RCA) #2 75%, #3 90%, LMT #5 50%, and left anterior descending (LAD) branch #7 75%). Plain Old Balloon Angioplasty (POBA) was performed on the responsible lesion, RCA (#2-3). Off-pump Coronary Artery Bypass Grafting (OPCAB) was initially planned for the remaining lesion. However, cardiogenic shock occurred, and an emergency OPCAB (SVG-LAD, SVG-#4PD) was performed via partial sternotomy (inverted L-shaped incision on the left side), using intra-aortic balloon pumping (IABP). The patient underwent revascularization using great saphenous vein grafts due to the potential for postoperative pleuroperitoneal communication in patients undergoing peritoneal dialysis, as well as the risk of impaired internal thoracic artery (ITA) flow caused by debranching in future involving internal shunts for dialysis. It is important to consider not only the graft but also the thoracotomy, taking into account the perspectives of early weaning and the prevention of perioperative complications.

We report on a rare case of a left subclavian artery aneurysm concomitant with Loeys-Dietz Syndrome (LDS) which required us to operate in childhood. A 12-year-old female, who had been diagnosed with LDS by genetic examination one year eariler, was revealed to be suffering from a left subclavian artery aneurysm (25 mm in diameter) by follow up chest MRI scan. Hybrid surgery consisting of coil embolization of aneurysm and surgical revascularization of the left subclavian artery and left vertebral artery was performed successfully. The patient was discharged on postoperative day 8.

Objective: In recent years, repetitive transcranial magnetic stimulation (rTMS) has shown promise in treating aphasia. While previous reports used the Standard Language Test of Aphasia (SLTA) for evaluation of language functions, the difficulty level of each task in SLTA varies. To show the effects of rTMS in more detail, it is necessary to use weighted values for the SLTA scores. This study aimed to assess the impact of high-frequency rTMS on aphasia using the deviation values of the SLTA.Methods: Thirty-one post-stroke aphasic patients participated in this study [mean (SD) age 58.0 (10.1) years, 15 infarction and 16 hemorrhage] from 2017 to 2021. The average (SD) duration from the onset of stroke to the intervention was 41.1 (31.1) months. Prior to admission, brain sites for rTMS were determined by detecting activation during the word-repeat task using functional MRI. A two-week inpatient treatment, including daily high-frequency rTMS and speech language hearing therapy (excluding Sundays), was conducted. In statistical analysis, SLTA scores were converted into deviation values, with participants grouped by rTMS sites (frontal lobe, temporal lobe, left/right hemisphere) for pre- and post-treatment comparisons.Results: rTMS sites included right frontal lobe (6 cases), left frontal lobe (10 cases), right temporal lobe (5 cases), and left temporal lobe (10 cases). Pre- and post-treatment comparisons showed significant improvements in overall mean scores and speech items in all groups. Additionally, significant enhancements in auditory comprehension items were observed in the right hemisphere and frontal lobe stimulation groups.Conclusion: High-frequency rTMS shows promise that it can improve language function regardless of the stimulation site, and auditory comprehension may be improved specifically by the right hemisphere and left frontal lobe stimulation. This suggests its potential as a valuable therapeutic intervention.

Background/Aims:
Pathological evaluation is crucial for diagnosing biliary lesions and determining appropriate treatment strategies. However, tissue sampling via the transpapillary route can be difficult. In this study, we aimed to assess the efficacy and safety of a novel tapered-tip sheath system for tissue sampling from biliary strictures.
Methods:
This single-center, randomized, parallel-group clinical trial included patients aged 20 to 85 years admitted to Kyoto University Hospital for biliary strictures. The patients were randomly assigned (1:1) to a new or conventional method group. The primary outcome was technical success of biopsy at the target bile duct using the assigned method, as determined in accordance with the intention-to-treat principle. Adverse events were assessed in all eligible patients.
Results:
Fifty-six patients were assessed for eligibility between September 2020 and March 2023; 50 patients were enrolled. The patients were randomly divided into the new (n=25) method group and the conventional (n=25) method group. Technical success was achieved in 96.0% (24/25) and 48.0% (12/25) of patients in the new and conventional method groups, respectively (risk ratio, 2.00; 95% confidence interval [CI], 1.32 to 3.03; risk difference, 48.0%; 95% CI, 27.0% to 69.0%; p<0.001). Adverse events occurred in 4.0% (1/25) and 36.0% (9/25) of patients in the new and conventional method groups, respectively (risk ratio, 0.11; 95% CI, 0.02 to 0.81; risk difference, –32.0%; 95% CI, –52.3% to –11.7%; p=0.005).
Conclusions
The novel tapered-tip sheath system is a promising option for precisely and safely delivering biopsy forceps to target sites, thereby facilitating the diagnosis of biliary strictures.

International Journal of Gastrointestinal Intervention 2025;14(1):2-8
Background:
No studies have compared balloon-assisted endoscope-guided endoscopic retrograde cholangiopancreatography (BAE-ERCP) and endoscopic ultrasonography-guided biliary drainage (EUS-BD) for emergent treatment of acute cholangitis (AC) in patients with upper gastrointestinal surgically altered anatomy (SAA).
Methods:
This study retrospectively evaluated consecutive patients who underwent emergent BAE-ERCP or EUS-BD for AC with SAA between January 2020 and March 2024. Technical success, clinical success, procedure time, and adverse events (AEs) were compared between the two groups.
Results:
This study included 23 patients in the BAE-ERCP group and 14 patients in the EUS-BD group. Technical success and clinical success rates did not significantly differ between the two groups (88% vs. 100%, P = 0.51 and 95% vs. 93%, P = 0.66). Similarly, the rate of AEs was comparable between the two groups (4% vs. 14%, P = 0.54). The median procedure time was significantly shorter in the EUS-BD group than in the BAE-ERCP group (32.5 [interquartile range; IQR, 28.8–52.5] minutes vs. 70.0 [IQR, 60.0–90.0] minutes, P < 0.01). In cases with grade 2 or 3 cholangitis, the rates of technical success, clinical success, and AEs did not significantly differ between the two groups. However, the median procedure time was significantly shorter in the EUS-BD group than in the BAE-ERCP group (32.5 [IQR, 28.8–52.5] minutes vs. 70 [IQR, 56.3–90.0] minutes, P < 0.01).
Conclusion
While both BAE-ERCP and EUS-BD can be performed safely and effectively in patients with AC and SAA, the procedure time is significantly shorter with EUS-BD than with BAE-ERCP.

Background:
Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) has been recognized as an effective treatment for patients at high risk for surgery. An antimigration metal stent with tapered thin delivery system has recently been developed. The aims of this study were to evaluate the feasibility, safety, and longterm outcomes of EUS-GBD using the new metal stent.
Methods:
Between April 2017 and March 2020, 21 patients with acute cholecystitis unsuitable for cholecystectomy underwent EUS-GBD using the metal stent. The stent was 6 mm in diameter and 6 cm in length, with a large flare at both ends for antimigration, and mounted in a 7.5 Fr delivery catheter, which requires no dilation devices. We retrospectively evaluated clinical and technical success, adverse events, and stent patency.
Results:
The technical and clinical success rates of EUS-GBD using the metal stent were 95.2% and 100%, respectively. For 75% of the patients, metal stents could be placed without dilatation of the needle tract. These patients had significantly shorter procedure time (23.6 ± 9.8 min) than patients requiring needle tract dilatation (38.4 ± 17.1 min; P = 0.036). The median follow-up periods were 336 days (interquartile range [IQR] 152–919 days) and 1,135 days (IQR 1,009–1,675 days) for all and alive patients, respectively. No adverse events or recurrence of cholecystitis due to stent occlusion that occurred in any patient at follow-up was observed.
Conclusion
In conclusion, EUS-GBD using the newly designed metal stent showed excellent safety and longterm outcomes, and may be suitable as an alternative treatment in patients who are unsuitable for cholecystectomy.
