Positron emission tomography in the evaluation of endometriosis: A systematic review.

Despite the profound impact of endometriosis worldwide, delays in diagnosis and suboptimal surveillance techniques are well-recognised issues. Case studies have reported incidental uptake of 18F-FDG PET tracer in endometriotic lesions. However, the utility of PET imaging as a non-invasive diagnostic tool for endometriosis is currently unclear. The purpose of this systematic review was to summarise the existing evidence and determine the value of available PET scanning techniques in the detection and monitoring of endometriosis. MEDLINE, EMBASE, CENTRAL, SCOPUS and Web of Science were searched from conception to 05/03/23. Eligible studies included participants with a history of known or suspected endometriosis who underwent a PET scan for any indication. All PET tracers and protocols were eligible. Outcomes included correlation of PET tracer uptake with the presence of endometriosis seen at laparoscopy or confirmed on histology, sensitivity of tracer uptake, specificity of tracer uptake, site of lesions with tracer uptake, stage of lesions with tracer uptake, SUVmax of endometriosis lesions and adverse reactions to PET imaging. The protocol for this review was registered with PROSPERO (ID: CRD42023405260). Eight studies describing 110 participants were eligible for inclusion. Six studies assessed 18F-FDG with combined PET-CT, one study assessed 18F-FDG PET alone, and the remaining study assessed PET-CT with an alternative tracer, 68Ga-DOTATATE. For 18F-FDG imaging, the correlation of PET avidity with lesions or sites of endometriosis ranged from 0-55 %. Pre-operative 68Ga-DOTATATE PET-CT detected endometriosis in 33 % of cases. All included studies were cohort studies, six were assessed to have low risk of bias, one with moderate risk and one with high risk of bias. Overall, 18F-FDG PET scanning does not appear to consistently identify endometriotic lesions, and therefore its reliability and usefulness in endometriosis diagnosis is limited. The utility of 68Ga-DOTATATE PET-CT remains uncertain. Findings are constrained by limited available evidence reporting outcomes of PET imaging for endometriosis. Other existing PET tracers with biological plausibility in the detection or monitoring of endometriosis warrant further investigation.

The relationship between sleep disturbances and endometriosis: A systematic review.

OBJECTIVE: Endometriosis is associated with a range of symptoms that can negatively impact a person's quality of life. While pain and infertility have received at lot of attention, sleep disturbances in individuals with endometriosis has been overlooked in both clinical practice and research. Therefore, the primary aim of this systematic review was to gather evidence from the current literature to illustrate the association between sleep disturbances and endometriosis. STUDY DESIGN: A literature search was conducted using three electronic databases (OVID EMBASE, MEDLINE, and Web of Science). Observational studies, published in English, that involved participants aged 18 years or older that compared sleep outcomes between endometriosis patients and those without a history of endometriosis were included. The quality of each study was assessed using the Joanna Briggs Institute critical appraisal tools. RESULTS: Nine studies (six case-control and three cross-sectional) were included in this review; 7 with low risk of bias and 2 with moderate risk of bias. The studies demonstrated heterogeneity in the assessment of sleep disturbances. However, 7 studies reported a significant positive association between endometriosis and sleep disturbances. Moreover, this impact on sleep was further complicated by the complex interaction between pain, fatigue and quality of life. CONCLUSION: Current studies suggest an association between sleep disturbances and endometriosis, which may provide a blueprint for future clinical recommendations to screen and treat sleep disturbances in individuals with endometriosis to improve their quality of life. Future studies should aim to standardise the methods of assessing sleep disturbances and explore potential contributing factors.

Evidence for the role of multidisciplinary team care in people with pelvic pain and endometriosis: A systematic review.

BACKGROUND: Endometriosis is a chronic, inflammatory condition characterised by the presence of endometrial-like tissue outside the uterine cavity. Given the multi-system nature of the disease and the potential for significant negative impact on quality of life, there has been a long-standing recognition of the need for multidisciplinary care for people with endometriosis. However, there is paucity to the data supporting this approach, and much of the evidence is anecdotal. AIM: This systematic review aims to describe recent evidence-based models and patient-centred perspectives of multidisciplinary care for endometriosis, to improve understanding of the role of an integrated, multidisciplinary team in effectively addressing patients' care needs. MATERIALS AND METHODS: PubMed, Medline, Embase and Web of Science were searched for relevant articles published between 1 January 2010 to 7 July 2022. RESULTS: Nineteen studies met the inclusion and exclusion criteria and pinpointed a multidisciplinary team consisting of gynaecologists, pain specialists, nurses, physiotherapists, psychologists, sex therapists, nutritionists, complementary medicine practitioners, and social workers to be most commonly utilised in holistically managing people with pelvic pain and endometriosis. Furthermore, patient perspectives on care highlighted the need for reliable information, respect and validation of experiences or preferences, discussion of long-term treatment plans and social and emotional supports. CONCLUSION: The trend for multidisciplinary team care for people with endometriosis is growing. Further consumer-driven clinical studies and outcome evaluations need to be conducted to determine the effect of multidisciplinary care on improvements to quality of life for people living with endometriosis and or pelvic pain.

A dedicated antenatal clinic for pregnant women with morbid and super-obesity: Patient characteristics, outcomes, perceptions and lessons learnt from establishing the DIAMOND clinic.

BACKGROUND: The DIAMOND antenatal clinic was established to provide multidisciplinary continuity of care to pregnant women living with morbid (body mass index (BMI) ≥40 kg/m2 ) or super-obesity (BMI ≥50 kg/m2 ). AIM: The aim was to describe clinic processes, demographics, clinical outcomes and women's perceptions of the clinic. METHODS: Women who received antenatal care in the clinic between 2016 and 2019 (n = 257) had routine data collected for retrospective analysis. A patient satisfaction survey was conducted for women who received care in 2019 (n = 89). RESULTS: The median BMI was 49 kg/m2 (max = 81 kg/m2 ). The mean age was 32 years. The largest proportion of women (27.6%) resided in the most disadvantaged suburbs of the region. Primipara comprised 29.6%, and 4.7% of women identified as Aboriginal or Torres Strait Islander. Diabetes was present in 47.5%, and 9.3% developed pre-eclampsia. Half (49.4%) had their labour induced (49.8% required cervical ripening), and 37% had an elective caesarean section. Almost a quarter (24.1%) of women underwent emergency caesarean section. One in six women had a measured blood loss of more than 1000 mL. The unadjusted stillbirth rate was 0.8%. Blood transfusions were required by 3.9%, and 1.9% of women required intensive care admission. Survey responses showed women valued the clinic for the enhanced surveillance, continuity, care coordination and respectful care. Improvements to waiting times were recommended. CONCLUSIONS: Establishing a dedicated clinic for women living with high BMI provides a well-liked environment for a high-risk cohort of women. Our review identified opportunities for improvement in clinic processes. We plan to assess overall impact on perinatal outcomes.

Comparison of Organoids from Menstrual Fluid and Hormone-Treated Endometrium: Novel Tools for Gynecological Research.

Endometrial organoids (EMO) are an important tool for gynecological research but have been limited by generation from (1) invasively acquired tissues and thus advanced disease states and (2) from women who are not taking hormones, thus excluding 50% of the female reproductive-aged population. We sought to overcome these limitations by generating organoids from (1) menstrual fluid (MF; MFO) using a method that enables the concurrent isolation of menstrual fluid supernatant, stromal cells, and leukocytes and (2) from biopsies and hysterectomy samples from women taking hormonal medication (EMO-H). MF was collected in a menstrual cup for 4-6 h on day 2 of menstruation. Biopsies and hysterectomies were obtained during laparoscopic surgery. Organoids were generated from all sample types, with MFO and EMO-H showing similar cell proliferation rates, proportion and localization of the endometrial basalis epithelial marker, Stage Specific Embryonic Antigen-1 (SSEA-1), and gene expression profiles. Organoids from different disease states showed the moderate clustering of epithelial secretory and androgen receptor signaling genes. Thus, MFO and EMO-H are novel organoids that share similar features to EMO but with the advantage of (1) MFO being obtained non-invasively and (2) EMO-H being obtained from 50% of the women who are not currently being studied through standard methods. Thus, MFO and EMO-H are likely to prove to be invaluable tools for gynecological research, enabling the population-wide assessment of endometrial health and personalized medicine.

Concordance of maternal and paternal decision-making and its effect on choice for vaginal birth after caesarean section.

BACKGROUND: The proportion of women who plan for a repeat elective caesarean section (CS) is one of the major determinants of the overall rate of CS, and programs aiming to reduce the rate of CS have not been greatly successful. To date, there appear to have been no large studies directly addressing paternal influences on decision-making regarding vaginal birth after caesarean (VBAC). This study aimed to compare the reactions of fathers and mothers to the prospect of VBAC. METHODS: Couples were recruited from three Australian hospitals and were eligible with a singleton pregnancy, a normal morphology ultrasound, and where there was no condition in the new pregnancy that would preclude a vaginal birth. Questionnaires were scheduled for 20 weeks' gestation, 32-36 weeks' gestation and six weeks postnatal and were sent separately to each partner. RESULTS: Seventy-five couples completed the full sets of questionnaires during the study period. In total, 31 women (41%) ultimately attempted vaginal delivery, and 44 (59%) were delivered by planned CS. When the paternal rating of risk fell between the second and third trimesters, the couple were likely to attempt VBAC (P < 0.05). Where the maternal rating of importance was 3 or less, 92% had a planned CS compared to 63% for the same paternal scores (P = 0.02). CONCLUSION: This study suggests that interventions that improve the paternal perceptions of risk during a pregnancy might increase the chance that a couple will attempt VBAC.
