Article Abstract
This study aimed to study the expression of homeobox (HOX)A11-AS1 ( HOXA11 antisense RNA) long noncoding RNA (lncRNA) and the expression of homeobox A ( HOXA9, HOXA10, HOXA11, and HOXA13) genes in the eutopic (EU) and ectopic (EC) endometria of women with peritoneal endometriosis. A total of 30 women undergoing laparoscopic surgery for peritoneal endometriosis and 15 infertile women without endometriosis were enrolled in this study. Peritoneal EC tissue samples were obtained through surgery. The EU tissues were obtained by curettage. The EC and EU lncRNA and messenger RNA (mRNA) expression levels were measured using real-time reverse transcriptase-polymerase chain reaction. The HOXA11-AS1 lncRNA and HOXA9, HOXA10, HOXA11, and HOXA13 mRNA were expressed at significantly lower levels in the EU than in the EC, that is, in women with peritoneal endometriosis ( P < .05). The expression levels of HOXA10 and HOXA11 in the EU were significantly lower in women with peritoneal endometriosis compared to the control group participants ( P < .05), whereas the levels of lncRNA ( HOXA11-AS1), HOXA9, and HOXA13 did not differ significantly between the 2 patient groups ( P > .05). In conclusion, the study findings suggest that HOXA11-AS1 lncRNA may play a role in the development of peritoneal endometriosis, but HOXA11-AS1 may not influence endometrial receptivity in endometriosis-associated infertility.

Objective: Exosomes are secreted by most cell types and reflect the internal state of their cells of origin, playing crucial roles in the progression of various pathological conditions. Endometriosis is a chronic, estrogen-dependent inflammatory disease characterized by the ectopic presence of endometrial-like tissue outside the uterus, including in the ovaries, fallopian tubes, and peritoneal cavity. It primarily affects women of reproductive age and is often associated with infertility.

The leading hypothesis for disease etiology is via the reflux of menstrual effluent (ME) into the peritoneal cavity. ME is a complex mixture of viable endometrial tissue, proteins, and immune cells which serve specialized functions during menstruation to support and repair the endometrium.

One of its main symptoms is chronic pain and inflammation leading to a decreased quality of life. This is a common disease, as at least one in ten female-born individuals have endometriosis.

Study Question: How reliable are self-reported endometriosis or adenomyosis data compared with medical reports in online patient surveys?
Summary Answer: In our sample, reliability was strong to excellent for diagnosis, age at diagnosis, and stage at diagnosis, while reliability for macro-phenotype of endometriosis ranged from fair to substantial.
What Is Known Already: Many online surveys rely on self-reported endometriosis data. Previous research has shown validation rates ranging from 72% to 95% for self-reported endometriosis diagnosis in population cohorts, but this rate is unknown in the context of online surveys among patient populations or patient e-cohorts.

Background/aim: Endometriosis is characterized by the accumulation of immune cells in endometrial lesions and the peritoneal cavity. Macrophages contribute to the growth and neovascularization of endometriotic lesions. Vascular endothelial growth factor receptor-1 (VEGFR1) is involved in neovascularization, while peritoneal macrophages (PMs) play a critical role in endometriosis development and establishment.
