Association between Fractures and Low Muscle Mass in Korean Menopausal Women: Data from Korean National Health and Nutrition Survey (2010–2011)

Objectives@#This study used the Korean National Health and Nutrition Examination Survey (KNHANES) to determine the association between fractures and low muscle mass. @*Methods@#This cross-sectional study used the 2010–2011 KNHANES data. Low muscle mass was defined as (appendicular skeletal muscle mass [kg]/Height2 [m2 ]) < 5.45 kg/m2 , which is < 2 SD below the sex-specific mean of a young reference group. Patients with T-scores between –1.0 and –2.5 indicated osteopenia, whereas those with T-scores lower than –2.5 indicated osteoporosis. @*Results@#Out of 1,306 women enrolled in the study, 330 were diagnosed with low muscle mass according to the abovementioned diagnostic criterion. The prevalence of fractures at various sites was significantly higher in postmenopausal women with low muscle mass than in those without low muscle mass (relative risk [RR], 1.64; odds ratio [OR], 1.62; 95% confidence interval [CI], 1.06–2.48; P = 0.027). Furthermore, the prevalence of fractures was increased by the presence of osteopenia or osteoporosis in addition to low muscle mass (RR, 1.59; OR, 1.60; 95% CI, 1.02–2.49; P = 0.039) and by osteoporosis only (RR, 2.12; OR, 2.29; 95% CI, 1.11–4.70; P = 0.025). @*Conclusions@#Fracture was more prevalent in postmenopausal women with low muscle mass than in those without low muscle mass.This finding is consistent in a subgroup analysis that included women who had osteoporosis or osteopenia. Moreover, the risk of fractures increased as low muscle mass worsened.

MicroRNA-139-5p Regulates Fibrotic Potentials via Modulation of Collagen Type 1 and Phosphorylated p38 MAPK in Uterine Leiomyoma

Purpose@#This study aimed to elucidate whether microRNA-139-5p is involved in the pathogenesis of uterine leiomyoma. @*Materials and Methods@#Human leiomyoma and matched human smooth muscle samples were obtained from 10 women who underwent hysterectomy for uterine leiomyoma. MicroRNA (miRNA) expression was analyzed by quantitative real-time polymerase chain reaction. To assess the effects of miR-139-5p on cultured leiomyoma cells, cell migration, collagen gel contraction, wound healing, and the expression levels of hallmark proteins were evaluated in cells transfected with a miR-139-5p mimic. @*Results@#The expression of miR-139-5p was significantly lower in leiomyoma tissues than in matched smooth muscle tissues. Restored miR-139-5p expression in miR-139-5p mimic-transfected human leiomyoma cells resulted in decreased contractility of the ECM and cell migration. In addition, upregulation of miR-139-5p decreased the protein expression of collagen type 1 and phosphorylated p38 MAPK. @*Conclusion@#Expression of miR-139-5p is downregulated in leiomyoma cells and modulation of miR-139-5p may be involved in the pathogenesis of leiomyomas through the regulation of collagen type 1 and phosphorylated p38 MAPK. Therefore, miR-139-5p is a potential therapeutic target for leiomyoma.

Diagnosis and treatment of endometriosis

Endometriosis is a common gynecological condition characterized by chronic pelvic pain, dysmenorrhea and subfertility. However, the pathophysiology of the disease remains unclear and accurate non-invasive diagnostic methods are unavailable. Although clinical symptoms, serum biomarkers, and imaging studies, such as transvaginal ultrasonography and magnetic resonance imaging are useful diagnostic aids, laparoscopy remains the gold standard for the diagnosis of endometriosis. The treatment of endometriosis should be individualized and a multi-disciplinary approach is recommended based on degree of disease-associated symptoms, patient characteristics and preferences, reproductive plans, and desired quality of life. Surgical management is effective for subfertility, chronic pain, and ovarian endometriomas. The principle of surgery is removal of all ectopic endometrial lesions while ensuring that no lesions are missed. Currently, numerous medical treatment options are available to manage endometriosis-associated symptoms; however, all modalities are suppressive rather than curative. Further studies are needed to clarify the exact pathophysiology of endometriosis to enable the development of non-invasive diagnostic tools for early detection and to indicate potential therapeutic targets for this chronic and frustrating disease.
