Teriparatide, denosumab, alendronate, and risedronate are effective in reducing the risk of vertebral and nonvertebral fractures in postmenopausal women with osteoporosis. Furthermore, denosumab, alendronate, and risedronate can reduce the risk of hip fracture, and risedronate can also reduce the risk of upper-arm fracture.

Our results suggest that AGFs downregulated IL-1beta-induced chondrocyte ageing and overexpression of caveolin-1 in human chondrocytes, which is mediated by kinase cascades involving the p42/44 MAP kinase and PI3-K/Akt signalling pathways.

Background and Objective Loxoprofen (LOX) is a nonsteroidal anti-inflammatory drug (NSAID). Although oral administration of LOX has been widely prescribed, clinical guidelines for osteoarthritis generally recommend topical rather than oral NSAIDs in specific patients. However, there is limited information on the effects of loxoprofen sodium oral (LOX-O) versus loxoprofen sodium hydrogel transdermal patch (LOX-T) in myalgia patients. Hence, this non-inferiority study was designed to compare the efficacy and safety of LOX-O versus LOX-T in Chinese patients with myalgia. Methods In this double-blind, double-dummy, parallel-group, randomized controlled trial, 182 Chinese patients were enrolled and randomized equally to either LOX-T or LOX-O treatment for 2 weeks. Patients in the LOX-T group applied one sheet of the active LOX-T once a day on the affected site and took one placebo tablet three times a day immediately after meals, whereas patients in the LOX-O group applied one sheet of the placebo patch once a day and took one active LOX-O three times a day. Primary endpoint was the proportion of patients with 50% overall improvement or higher at the final visit. The cutoff value of a non-inferiority difference was set as − 10%. Results In the full analysis set, the primary endpoint of final efficacy rate was 81.3% ( n = 91) in the LOX-T group and 72.2% ( n = 88) in the LOX-O group. The difference between the two groups was 9.1% [95% confidence interval (CI) − 3.1 to 21.3%], which showed that LOX-T was non-inferior compared with LOX-O. No serious adverse events occurred in either group. Conclusions This trial showed the non-inferiority of LOX-T compared with LOX-O in efficacy and safety in Chinese patients with myalgia. Also, the characteristic features of topical LOX-T, such as better compliance and lower risk-benefit ratio, make it more favorable for clinical practice. Trial Registration The study was registered in the isrctn.com registry (ISRCTN trial ID: ISRCTN16227145).

This study aimed to assess the responsiveness of ultrasonography (US)-7 in patients with rheumatoid arthritis (RA). Eighty-two RA patients were recruited and followed up for 22 weeks. The clinical, laboratory, and X-ray assessments, along with grayscale US (GSUS) and power Doppler US (PDUS) examinations were performed at baseline, 6, 14, and 22 weeks after infliximab treatment. GSUS for synovitis and PDUS for synovitis and paratendinitis/tenosynovitis were assessed by a semi-quantitative (0 to 3) score, while GSUS for paratendinitis/tenosynovitis and bone erosion was qualitatively assessed as absent or present (0 or 1). US scores in both 7-joint (US7) and 12-joint (US12) systems were evaluated. After 6, 14, and 22 weeks of treatment with infliximab, indices such as US scores, 28-joint disease activity (DAS28) score, and tender and swelling joint count were all significantly improved compared to baseline. US7 scores were significantly correlated with that of US12. Strong correlations were identified between most US7 scores with DAS28, health assessment questionnaire (HAQ), and C-reactive protein (CRP) levels. When DAS28 was used as a reference, the US7 cutoff for disease remission was less than 35 for GS + PD and also less than 29 for GS and 1 for PD, respectively. Additionally, the positive percent agreement, negative percent agreement, and overall percent agreement for GS + PD were 77.78, 76.19, and 76.67 %, respectively, which were all higher than that of GS or PD. US7 may be a feasible tool to assess the therapeutic response in RA patients.
