Efficacy of IOTA simple rules, O-RADS, and CA125 to distinguish benign and malignant adnexal masses.

OBJECTIVE: Ovarian cancer is the most deadly deadliest gynecological tumor in the female reproductive system. Therefore, the present study sought to determine the diagnostic performance of International Ovarian Tumor Analysis Simple Rules (IOTA SR), the Ovarian-Adnexal Reporting and Data System (O-RADS), and Cancer Antigen 125 (CA125) in discriminating benign and malignant ovarian tumors. The study also assessed whether a combination of the two ultrasound categories systems and CA125 can improve the diagnostic performance. METHODS: A total of 453 patients diagnosed with ovarian tumors were retrospectively enrolled from Fujian Cancer Hospital between January 2017 and September 2020. The data collected from patients included age, maximum lesion diameter, location, histopathology, levels of CA125, and detailed ultrasound reports. Additionally, all ultrasound images were independently assessed by two ultrasound physicians with more than 5 years of experience in the field, according to the IOTA simple rules and O-RADS guidelines. Furthermore, the area under the curve (AUC), sensitivity, and specificity of the above mentioned predictors were calculated using the receiver operating characteristic curve. RESULTS: Out of the 453 patients, 184 had benign lesions, while 269 had malignant ovarian tumors. In addition, the AUCs of IOTA SR, O-RADS, and CA125 in the overall population were 0.831, 0.804, and 0.812, respectively, and the sensitivities of IOTA SR, O-RADS, and CA125 were 94.42, 94.42, and 80.30%, respectively. On the other hand, the AUCs of IOTA SR combined with CA125, O-RADS combined with CA125, and IOTA SR plus O-RADS combined with CA125 were 0.900, 0.891, and 0.909, respectively. The findings also showed that the AUCs of a combination of the three approaches were significantly higher than those of individual strategies (p<0.05) but not significantly higher than the AUC of a combination of two methods (p>0.05). CONCLUSION: The findings showed that a combination of IOTA SR or O-RADS in combination with CA125 may improve the ability to distinguish benign from malignant ovarian tumors.

Menopausal Symptoms and Sleep Quality During Menopausal Transition and Postmenopause.

BACKGROUND: Menopausal symptoms and sleep difficulty were physiological processes that were affected by genetic and other factors. This study was to investigate the prevalence of menopausal symptoms and sleep quality in menopausal transition (MT) and postmenopause (PM) women in Taiyuan, Shanxi. METHODS: A community-based survey of women's menopausal symptoms and sleep quality was conducted between July 2012 and May 2013 at six municipal districts of Taiyuan, Shanxi. A sample of 2429 women aged 40-59 years was divided into four groups: early MT, late MT, early PM, and late PM. Sleep quality in the past 2 weeks before the interview was recorded. The data were analyzed using SPSS 16.0. RESULTS: The prevalence of menopausal symptoms was 49.8%. Mild, moderate, and severe symptoms were observed in 28.9%, 18.5%, and 2.5% of participants, respectively. The highest prevalence of menopausal symptoms occurred in the early postmenopausal stage; the subsequences were the late postmenopausal stage and the early MT stage. Interestingly, among the 13 items of modified Kupperman index, the five most common symptoms were fatigue, arthralgia and myalgia, decreased libido, insomnia, and nervousness. Meanwhile, 55% perimenopausal women had poor sleep. CONCLUSIONS: Menopausal symptoms are common but mild among women in Taiyuan, Shanxi during MT and PM. In these stages, the prevalence of poor sleep is high.

Effect of cervus and cucumis peptides on osteoblast activity and fracture healing in osteoporotic bone.

Osteoporosis is associated with delayed and/or reduced fracture healing. As cervus and cucumis are the traditional Chinese treatments for rheumatoid arthritis, we investigated the effect of supplementation of these peptides (CCP) on bone fracture healing in ovariectomized (OVX) osteoporotic rats in vitro and in vivo. CCP enhanced osteoblast proliferation and increased alkaline phosphatase activity, matrix mineralization, and expression of runt-related transcription factor 2 (Runx2), bone morphogenetic protein 4 (BMP4), and osteopontin. In vivo, female Sprague-Dawley rats underwent ovariectomy and the right femora were fractured and fixed by intramedullary nailing 3 months later. Rats received intraperitoneal injections of either CCP (1.67 mg/kg) or physiological saline every day for 30 days. Fracture healing and callus formation were evaluated by radiography, micro-CT, biomechanical testing, and histology. At 12 weeks after fracture, calluses in CCP-treated bones showed significantly higher torsional strength and greater stiffness than control-treated bones. Bones in CCP-treated rats reunified and were thoroughly remodeled, while two saline-treated rats showed no bone union and incomplete remodeling. Taken together, these results indicate that use of CCP after fracture in osteoporotic rats accelerates mineralization and osteogenesis and improves fracture healing.
