Black cohosh extract (BCE) is a widely used dietary supplement marketed to women to alleviate symptoms of gynecological ailments, yet its toxicity has not been well characterized. The National Toxicology Program (NTP) previously reported significant increases in micronucleated erythrocytes in peripheral blood of female Wistar Han rats and B6C3F1/N mice administered 15-1,000 mg BCE/kg/day by gavage for 90 days. These animals also developed a dose-dependent nonregenerative macrocytic anemia characterized by clinical changes consistent with megaloblastic anemia...

BACKGROUND: Impaired healing of the uterine scar after cesarean has been associated with adverse gynecological and obstetric outcomes. Although a large number of studies have been conducted on the events leading to this, information obtained from prospective randomized studies examining the role of suture material in the formation of cesarean scar defect (CSD) is lacking. OBJECTIVE: To evaluate the effects of synthetic suture materials on CSD formation. STUDY DESIGN: We performed a two-arm 1:1 randomized study in women with singleton pregnancies undergoing elective primary cesarean delivery after the 38th week of gestation...

Noncaseating granulomas are seen surrounding tumors with varying frequency, possibly as part of an immune response to tumor cells. However, data about the association of sarcoid with gynecologic malignancy is sparse. We performed a search of our institutional database for all EBUS-TBNA biopsies conducted within the past five years that revealed granulomatous inflammation. All adult female patients with a history of gynecologic malignancy were included. Patients with a history of sarcoidosis or fungal or mycobacterial infection were excluded...

Endometrial carcinoma (EC) is the most common malignant gynecologic tumor in women. EC is thought to be caused by increasing estrogen levels relative to progesterone in the body. Hesperidin (Hsd), a biologically active flavonoid, could be extracted from Citrus species. It has been recently shown that Hsd could exert anticarcinogenic properties in different cancer types. However, the effects of Hsd and its molecular mechanisms on EC remain unclear. In this study, the antiproliferative, apoptotic and genomic effects of Hsd in EC and its underlying mechanisms were identified...

BACKGROUND: Quality of life (QoL) is important for clinicians to evaluate how cancer survivors judge their sense of well-being, and WHOQOL-BREF may be a good tool for clinical use. However, at least three issues remain unresolved: (1) the psychometric properties of the WHOQOL-BREF for cancer patients are insufficient; (2) the scoring method used for WHOQOL-BREF needs to be clarify; (3) whether different types of cancer patients interpret the WHOQOL-BREF similarly. METHODS: We recruited 1000 outpatients with head/neck cancer, 1000 with colorectal cancer, 965 with liver cancer, 1438 with lung cancer and 1299 with gynecologic cancers in a medical center...

BACKGROUND: Ovarian cancer is one of the most deadly gynecological malignancies and inclined to recurrence and drug resistance. Previous studies showed that the tumorigenesis of ovarian cancers and their major histotypes are associated with genomic instability caused by defined sets of pathogenic mutations. In contrast, the mechanism that influences the development of drug resistance and disease recurrence is not well elucidated. Solid tumors are prone to chromosomal instability (CIN) and micronuclei formation (MN)...

Background: Mutations in ALPL, which encodes tissue-nonspecific isozyme alkaline phosphatase (TNSALP), cause hypophosphatasia (HPP). HPP is suspected by a low serum alkaline phosphatase (AlkP). We hypothesized that some patients with bone or dental disease have undiagnosed HPP caused by ALPL variants. Our objective was to discover the prevalence of these gene variants in the Vanderbilt DNA biobank (BioVU) and to assess phenotypic associations. Methods: We identified subjects in BioVU, a repository of DNA, that had at least one of three known rare HPP disease-causing variants in ALPL: rs199669988, rs121918007, rs121918002...
