RESUMEN
PURPOSE: To evaluate the safety and efficacy of new staple-line reinforcement (SLR) in pulmonary resection through a prospective study and to compare the results of this study with historical control data in an exploratory study. METHODS: The subjects of this study were 48 patients who underwent thoracoscopic lobectomy. The primary endpoint was air leakage from the staple line. The secondary endpoints were the location of air leakage, duration of air leakage, and postoperative pulmonary complications. RESULTS: The incidence of intraoperative air leakage from the staple line was 6.3%. Three patients had prolonged air leakage as a postoperative pulmonary complication. No malfunction was found in patients who underwent SLR with the stapling device. When compared with the historical group, the SLR group had a significantly lower incidence of air leakage from the staple line (6.3% vs. 28.5%, P < 0.001) and significantly shorter indwelling chest drainage time (P = 0.049) and length of hospital stay (P < 0.001). CONCLUSIONS: The use of SLR in pulmonary resection was safe and effective. When compared with conventional products, SLR could control intraoperative air leakage from the staple line and shorten time needed for indwelling chest drainage and the length of hospital stay.

In this randomized, controlled trial, sequential therapy with once-weekly subcutaneous injection of teriparatide for 72 weeks, followed by alendronate for 48 weeks resulted in a significantly lower incidence of morphometric vertebral fracture than monotherapy with alendronate for 120 weeks in women with osteoporosis at high risk of fracture. PURPOSE: To determine whether the anti-fracture efficacy of sequential therapy with teriparatide, followed by alendronate is superior to that of monotherapy with alendronate, a prospective, randomized, open-label, blinded-endpoint trial was performed. METHODS: Japanese women aged at least 75 years were eligible for the study, if they had primary osteoporosis and if they were at high risk of fracture. Patients were randomly assigned (1:1) to receive the sequential therapy (once-weekly subcutaneous injection of teriparatide 56.5 µg for 72 weeks, followed by alendronate for 48 weeks) or monotherapy with alendronate for 120 weeks. The primary endpoint in the final analysis was the incidence of morphometric vertebral fracture during the 120-week follow-up period. RESULTS: Between October 2014 and June 2020, 505 patients in the sequential therapy group and 506 in the monotherapy group were enrolled. Of these, 489 and 496, respectively, were included in the main analysis. The incidence of morphometric vertebral fracture during the 120-week follow-up period in the sequential therapy group (64 per 627.5 person-years, annual incidence rate 0.1020) was significantly lower than that in the monotherapy group (126 per 844.2 person-years, annual incidence rate 0.1492), with a rate ratio of 0.69 (95% confidence interval 0.54 to 0.88, P < 0.01). After 72 weeks, no patient had a severe adverse event that was considered related to the study drug. CONCLUSION: Once-weekly injection of teriparatide, followed by alendronate resulted in a significantly lower incidence of morphometric vertebral fracture than alendronate monotherapy in women with osteoporosis who were at high risk of fracture.

Associations between urinary pentosidine, one of the advanced glycation end products in collagen, and the risk of fracture in patients with severe osteoporosis are unknown. In this study, we investigated whether the urinary pentosidine level is associated with the incidence of morphometric vertebral fracture and nonvertebral fracture using data of a randomized, controlled trial, JOINT-05. JOINT-05 enrolled Japanese women aged 75 years or older with primary osteoporosis. Patients were randomly assigned (1:1) to receive sequential therapy (teriparatide followed by alendronate) or monotherapy with alendronate for 120 weeks. Incidences of vertebral and nonvertebral fractures were assessed morphologically. During treatment, urinary levels of pentosidine and serum levels of bone turnover markers (osteocalcin, procollagen type I amino-terminal propeptide, and tartrate-resistant acid phosphatase 5b) were measured. A total of 967 patients with baseline pentosidine levels were included in the study. Of these, 137 had vertebral fractures, and 42 had nonvertebral fractures. The rate ratios for vertebral fracture for the second (30-39 pmol/mL), third (40-49 pmol/mL), and fourth quartile (≥50 pmol/mL) groups divided by pentosidine level compared with the first quartile (<30 pmol/mL) group were 1.65 (95% confidence interval [CI] 0.99-2.75, p = 0.06), 1.51 (95% CI 0.87-2.61, p = 0.14), and 1.69 (95% CI 1.01-2.83, p = 0.05), respectively. The corresponding rate ratios for nonvertebral fracture were 3.07 (95% CI 0.88-10.70, p = 0.08), 2.34 (95% CI 0.61-8.95, p = 0.22), and 3.95 (95% CI 1.14-13.67, p = 0.03), respectively. The association of the urinary pentosidine level with the incidence of nonvertebral fracture was the strongest among the biomarkers assessed in the study. In conclusion, the urinary pentosidine level was associated with the risk of fracture in patients with severe osteoporosis receiving teriparatide or alendronate. © 2022 The Authors.
