Not Having Been Breastfed May Protect Chinese Women From Developing Deep Infiltrating Endometriosis: Results From Subgroup Analyses of the FEELING Study.

Background: This study aimed to investigate potential factors, especially early-life exposures, associated with endometrioma (OMA) and/or deep infiltrating endometriosis (DIE) in Chinese women.

Methods: This is a subgroup analyses of the FEELING study, which was a case-control study that investigated the clinical, lifestyle, and environmental factors associated with OMA and/or DIE in China, Russia, and France. In this subgroup analysis, the data for the Chinese participants were further analyzed using logistic regression model.

Factors associated with deep infiltrating endometriosis versus ovarian endometrioma in China: a subgroup analysis from the FEELING study.

Background: To compare potential factors associated with deep infiltrating endometriosis (DIE) versus ovarian endometrioma (OMA) among endometriosis patients in China.

Methods: A subgroup analysis of factors associated with DIE versus OMA was performed in Chinese women from the FEELING study. This study included 156 OMA patients and 78 DIE patients.

Genome-wide profiling of long noncoding ribonucleic acid expression patterns in ovarian endometriosis by microarray.

Objective: To profile the long noncoding RNA (lncRNA) expression patterns in ovarian ectopic endometrial tissue compared with paired eutopic endometrial tissue.

Design: Genome-wide expression analysis of human tissue.

Setting: University hospital.

Prevalence and associated factors of female sexual dysfunction in women with endometriosis.

Objective: The issue of female sexual function is often overlooked in women with endometriosis, especially in mainland China. The objectives of this study were to estimate the prevalence and associated factors of female sexual dysfunction in endometriosis in China.

Methods: This cross-sectional study was conducted at a referral university hospital in Beijing, Peoples Republic of China from July 2011 to April 2012.

Translation and psychometric evaluation of the simplified Chinese-version Endometriosis Health Profile-30.

Study Question: What are the psychometric properties in mainland China of the 30-item Endometriosis Health Profile (EHP-30) translated into simplified Chinese?

Summary Answer: The simplified Chinese version of the EHP-30 is a valid, reliable and acceptable tool for the measurement of the health-related quality of life (HRQoL) of women with endometriosis in the context of mainland China.

What Is Known Already: Endometriosis can critically affect women's HRQoL. The EHP-30 is currently the most reliable instrument to measure the HRQoL in women with endometriosis.

Plasma miR-17-5p, miR-20a and miR-22 are down-regulated in women with endometriosis.

Study Question: Can plasma microRNAs be used as a non-invasive diagnostic test for the detection of endometriosis?

Summary Answer: Plasma miR-17-5p, miR-20a and miR-22 are down-regulated in women with endometriosis compared with those without endometriosis in mainland China.

What Is Known Already: There is currently a pressing need to develop a non-invasive diagnostic test for endometriosis. Altered circulating microRNA profiles have already been linked to various disease states.

Health-related quality of life in women with endometriosis: a systematic review.

Endometriosis has critical implications for women's quality of life. However, an overview of the current knowledge of this issue is limited. The objective of this systematic review was to determine the extent of endometriosis and its treatment upon women's health-related quality of life (HRQoL).
