AIMS/HYPOTHESIS: Endometriosis is a heterogeneous inflammatory condition that may influence long-term metabolic health. Prior studies have reported largely null associations with type 2 diabetes, potentially missing subtype-specific and sub…

OBJECTIVE: To study whether incident endometriosis diagnosis, staging, and typology are associated with concurrent elevated serum inflammatory markers interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor alpha (TNF- α ). …

Background: Individuals with endometriosis, a gynecologic condition affecting approximately 11% of people with a uterus, may have an elevated risk for developing cardiovascular disease (CVD) later in life. However, the mechanisms underlying…

BACKGROUND: While plausible mechanisms exist for an association between endometriosis and hypertriglyceridemia, prior studies have shown inconsistent findings, possibly due to the inability to assess endometriosis severity or subtypes. OBJ…

BACKGROUND: Endometriosis has been linked to cardiometabolic alterations, but whether these associations vary by disease severity or phenotype is unclear. We examined lipid profiles across endometriosis diagnosis, stage, and typology. MATE…

IMPORTANCE: Endometriosis has been associated with an increased risk of ovarian cancer; however, the associations between endometriosis subtypes and ovarian cancer histotypes have not been well-described. OBJECTIVE: To evaluate the associa…

(Abstracted from JAMA 2024;332(6):482–489 Ovarian, breast, and endometrial cancers are known to be associated with endometriosis. This study was designed to assess associations between endometriosis and its subtypes with the overall inciden…

BACKGROUND: Women with endometriosis may have an increased risk of adverse pregnancy outcomes. Research has focused on infertility clinic populations limiting generalisability. Few studies report differences by endometriosis severity. OBJE…

OBJECTIVE: To determine agreement on endometriosis diagnosis between real-time laparoscopy and subsequent expert review of digital images, operative reports, magnetic resonance imaging (MRI), and histopathology, viewed sequentially. DESIGN…

OBJECTIVE: To explore the relation between bisphenol A and 14 phthalate metabolites and endometriosis. DESIGN: Matched cohort design. SETTING: Fourteen clinical centers. PATIENT(S): The operative cohort comprised 495 women undergoing lap…

OBJECTIVE: We sought to identify risk factors for endometriosis and their consistency across study populations in the Endometriosis: Natural History, Diagnosis, and Outcomes (ENDO) Study. STUDY DESIGN: In this prospective matched, exposure…

There has been limited study of trace elements and endometriosis. Using a matched cohort design, 473 women aged 18-44 years were recruited into an operative cohort, along with 131 similarly aged women recruited into a population cohort. End…

ObjectiveThe purpose of this study was to determine outcomes, after the use of propensity score techniques, to create balanced groups according to whether a woman undergoes elective repeat cesarean delivery (ERCD) or trial of labor (TOL).St…

OBJECTIVE: To estimate the interrater and intrarater reliability of endometriosis diagnosis and severity of disease among gynecologic surgeons viewing operative digital images. METHODS: The study population comprised a random sample (n=148…

BACKGROUND: Environmental chemicals may be associated with endometriosis. No published research has focused on the possible role of perfluorochemicals (PFCs) despite their widespread presence in human tissues. METHODS: We formulated two sa…

BACKGROUND: An equivocal literature exists regarding the relation between persistent organochlorine pollutants (POPs) and endometriosis in women, with differences attributed to methodologies. OBJECTIVES: We assessed the association between…

OBJECTIVE: To estimate the incidence of endometriosis in an operative cohort of women seeking clinical care and in a matched population cohort to delineate more fully the scope and magnitude of endometriosis in the context of and beyond cli…

Background and Aims: Persistent organic pollutants (POPs) have been associated with endometriosis, though with equivocal results possibly reflecting choice of biospecimen. We sought to assess this ...

OBJECTIVE: To estimate the efficacy of antibiotic prophylaxis at the time of nonlaboring cesarean delivery in reducing postpartum infection-related complications. METHODS: We performed a secondary analysis of an observational study of cesa…
