The "freeze-all" strategy seems to improve the chances of birth in adenomyosis-affected women.

OBJECTIVE: To compare assisted reproductive technologies (ARTs) outcomes between fresh vs. freeze-all strategies in infertile women affected by adenomyosis. DESIGN: A single-center observational study. SETTINGS: University hospital-based research center. PATIENTS: Adenomyosis-affected women undergoing blastocyst embryo transfer after in vitro fertilization and intracytoplasmic sperm injection between January 1, 2018, and November 31, 2021. The diagnosis of adenomyosis was based on imaging criteria (i.e., transvaginal ultrasound and/or magnetic resonance imaging). INTERVENTION(S): Women who underwent a freeze-all strategy were compared with those who underwent a fresh embryo transfer (ET) strategy. MAIN OUTCOME MEASURE(S): Cumulative live birth rate (LBR). RESULTS: A total of 306 women were included in the analysis: 111 in the fresh ET group and 195 in the freeze-all group. The adenomyosis phenotype (internal diffuse adenomyosis, external focal adenomyosis, and adenomyoma) was not significantly different between the two groups. The cumulative LBR (86 [44.1%] vs. 34 [30.6%], respectively), and the cumulative ongoing pregnancy rate (88 [45.1%] vs. 36 [32.4%], respectively) were significantly higher in the freeze-all group compared with the fresh ET group. After multivariate logistic regression analysis, the freeze-all strategy in women with adenomyosis was associated with significantly higher odds of live birth compared with fresh ET (odds ratio = 1.80; 95% confidence interval = 1.02-3.16). CONCLUSION: The freeze-all strategy in women afflicted with adenomyosis undergoing ART was associated with significantly higher cumulative LBRs. Our preliminary results suggest that the freeze-all strategy is an attractive option that increases ART success rates. Additional studies, with a randomized design, should be conducted to further test whether the freeze-all strategy enhances the pregnancy rate in adenomyosis-affected women.

Magnetic resonance imaging presentation of diffuse and focal adenomyosis before and after pregnancy.

RESEARCH QUESTION: Is there a change in magnetic resonance imaging (MRI) criteria of diffuse and focal phenotypes of adenomyosis before and after pregnancy? DESIGN: A retrospective, monocentric, observational study in a single academic tertiary referral centre for endometriosis diagnosis and management. Women were followed for symptomatic adenomyosis, and without a prior history of surgery who give birth after 24+0 weeks. For each patient, pelvic MRI pre- and post-pregnancy was performed by two experienced radiologists with the same image acquisition protocol. Diffuse and focal adenomyosis MRI presentation were analysed before and after pregnancy. RESULTS: Between January 2010 and September 2020, of the 139 patients analysed, 96 (69.1%) had adenomyosis at MRI distributed as follow: 22 (15.8%) presented diffuse adenomyosis, 55 (39.6%) focal adenomyosis and 19 (13.7%) both phenotypes. The frequency of isolated diffuse adenomyosis on MRI was significantly lower before versus after pregnancy (n = 22 [15.8%] versus n = 41 [29.5%], P = 0.01). The frequency of isolated focal adenomyosis was significantly higher before pregnancy than after pregnancy (n = 55 [39.6%] versus n = 34 [24.5%], P = 0.01). The mean volume of all focal adenomyosis lesions on MRI decreased significantly after pregnancy, from 6.7 ± 2.5 mm3 to 6.4 ± 2.3 mm3, P = 0.01. CONCLUSION: The current data indicate that, based on MRI, there is an increase in diffuse adenomyosis and a decrease in focal adenomyosis after pregnancy.

Adolescent endometriosis: prevalence increases with age on magnetic resonance imaging scan.

OBJECTIVE: To evaluate the prevalence on magnetic resonance imaging (MRI) of ovarian endometrioma (OMA) and deep infiltrating endometriosis (DIE) in adolescents presenting with severe dysmenorrhea. DESIGN: Prospective study. SETTING: Clinic. PATIENT(S): A total of 345 adolescents aged 12-20 years referred to the radiologic MRI department unit between September 2019 and June 2020. INTERVENTION(S): Multiplanar pelvic MRI with cine MRI was performed. Data on the medical history with systematic questioning were collected for each patient before the scan. MAIN OUTCOME MEASURE(S): Data on the endometriosis phenotypes (OMA and/or DIE), distribution of anatomical lesions, and adenomyosis were evaluated and recorded using a dedicated MRI spreadsheet. Myometrial contractions were systematically reported for each case. The data were correlated with the characteristics of the patients and severity of painful symptoms evaluated using a visual analog scale. RESULT(S): The prevalence rates of endometriosis and adenomyosis were 39.3% (121 patients) and 11.4% (35 patients), respectively. Among the adolescents with endometriosis, 25 (20.7%) presented with OMA, and 107 (88.4%) presented with DIE. The odds ratios (confidence intervals) for each pairwise comparison between the age distributions were 2.3 (1.4-3.8) for 15-18 vs. <15 years of age and 3.3 (1.2-8.5) for 18-20 vs. <15 years of age, highlighting a predominance of cases after 18 years of age. Uterine contractions were visualized in 34.4% of cases, with no particular association with endometriosis. No clinical risk factor was identified as being particularly associated with endometriosis. Notably, the visual analog scale score was the same for cases with and without endometriosis. CONCLUSION(S): Severe endometriosis phenotypes (OMA and/or DIE) can be observed in adolescents with intense dysmenorrhea, with a linear increase in prevalence over time resulting in a clear predominance after 18 years of age. Endometriosis in adolescents is a challenging clinical problem with a long delay in diagnosis. Imaging can help reduce this delay in young patients with suggestive symptoms. CLINICAL TRIAL REGISTRATION NUMBER: NCT05153512.

Endometriosis increases the rate of spontaneous early miscarriage in women who have adenomyosis lesions.

RESEARCH QUESTION: In women with radiologically diagnosed adenomyosis, is the presence of endometriosis associated with a higher rate of miscarriage? DESIGN: An observational cohort study of women who received medical care for benign gynaecological conditions between May 2005 and May 2018. Women who had adenomyosis lesions visualized by uterine magnetic resonance imaging (MRI) were included. Women who had never been pregnant were excluded. Women with adenomyosis identified by MRI but who did not have endometriosis lesions (control group) were compared with women with adenomyosis and endometriosis lesions (study group). Primary outcome was rate of a previous history of early miscarriage. RESULTS: A total of 214 pregnancies in the study group and 53 pregnancies in the control group were analysed. The rate of a previous miscarriage was significantly higher among women with adenomyosis and endometriosis lesions compared with women in the control group (61/214 [28.5%] versus 6/53 [11.3%], respectively, P = 0.009). A multivariable generalized estimating equation logistic regression model, adjusted for adenomyosis and endometriosis phenotypes, found that the association between endometriosis and adenomyosis significantly increased the risk of miscarriage (OR 3.2, 95% CI 1.1 to 9.65). The risk was significantly higher with deep infiltrating endometriosis (OR 4.37, 95% CI 1.32 to 14.53). CONCLUSIONS: Women affected by endometriosis had a significantly higher rate of previous spontaneous miscarriage than women without endometriosis with adenomyosis lesions identified by MRI. Mechanistic studies are needed to establish the complex link between the presence of endometriosis and adenomyosis and the rate of spontaneous miscarriage.

Human placental perfusion measured using dynamic contrast enhancement MRI.

OBJECTIVES: To evaluate the feasibility of dynamic contrast enhanced magnetic resonance imaging (DCE MRI) and measure values of in vivo placental perfusion in women. METHODS: This study was part of the Placentimage trial (NCT01092949). Gadolinium-chelate (Gd) enhanced dynamic MRI was performed two days before termination of pregnancies at 16 to 34 weeks gestational age (GA). Quantitative analysis was performed using one-compartment intravascular modeling. DCE perfusion parameters were analyzed across GA and were compared in IUGR and AGA fetuses. RESULTS: 134 patients were enrolled. After quality control check, 62 DCE MRI were analyzed including 48 and 14 pregnancies with normal and abnormal karyotypes, respectively. Mean placental blood flow was 129±61 mL/min/100ml in cases with normal karyotypes. Fetuses affected by IUGR (n = 13) showed significantly lower total placental blood flow values than AGA fetuses (n = 35) (F total = 122±88 mL/min versus 259±34 mL/min, p = 0.002). DCE perfusion parameters showed a linear correlation with GA. CONCLUSIONS: Measuring placental perfusion in vivo is possible using DCE MRI. Although this study has many limitations it gives us the first DCE MRI values that provide a potential standard for future research into placental perfusion methods and suggests that placental functional parameters are altered in IUGR pregnancies.

Prenatal-onset of congenital neuronal ceroid lipofuscinosis with a novel CTSD mutation.

BACKGROUND: Neuronal ceroid lipofuscinoses (NCLs) form a clinically and genetically heterogeneous group of inherited neurodegenerative disorders that share common neuropathological features. Although they are the first cause of neurodegenerative disorders in children, their congenital forms are rarely documented. They are classically due to mutations in the CTSD gene (the CLN10 disease). Affected newborns usually present severe microcephaly, seizures and respiratory failure leading to death within the first postnatal days or weeks. CASES: We report on two siblings, in which exome sequencing identified a novel homozygous CTSD variant. The first sib presented at birth with seizures, rapidly progressive postnatal microcephaly and visual deficiency related to retinal dysfunction. Progressive neurological deterioration leads to death at the age of 24 months. Cathepsin D activity was reduced in the cultured fibroblasts of this patient. The second sib, a fetus of 36 weeks of gestation, was delivered after pregnancy termination for brain abnormalities (in accordance with French Legislation) suggesting a recurrence of the disease. Fetal postmortem examination disclosed neuropathological features consistent with NCL. CONCLUSIONS: Congenital NCL related to CTSD mutations is a neuronal storage disorder that produces in the developing brain diffuse neurodegeneration and white matter atrophy resulting in a progressive and rapidly lethal microcephaly.

MRI based morphological examination of the placenta.

Ultrasound is widely used as the initial diagnostic imaging modality during pregnancy with both high spatial and temporal resolution. Although MRI in pregnancy has long focused on the fetus, its use in placental imaging has greatly increased over recent years. In addition to the possibilities of evaluating function, MRI with a wide field of view and high contrast resolution allows characterization of placental anatomy, particularly in situations that are difficult to specify with ultrasound, especially for suspected placenta accreta. MRI also appears to be a particularly useful examination for the anatomical evaluation of the placenta independent of maternal body habitus or fetal position. Indeed, surprisingly little attention is paid to the placenta in MRI when the indication for the examination is fetal. Thus, some aspects of the placenta seem to us to be important to be recognized by the radiologist and to be described on the MRI report. In this review, we will describe MRI sequences used for, and common features seen in, imaging of i) the normal placenta, ii) abnormal aspects of the placenta that should be identified on MRI performed for fetal reason, and iii) placental anomalies for which placental MRI may be indicated.

Ultrasound and Fetal MRI Complementary Contributions to Appropriate Counseling in Small Bowel Obstruction.

OBJECTIVE: Bowel obstructions beyond the duodenum represent a heterogeneous group of congenital anomalies with a highly variable prognosis, the main issue being postnatal short bowel syndrome (SBS). The objective of our study was to evaluate the contributions of fetal MRI in cases of bowel obstruction. MATERIALS AND METHODS: A retrospective analysis of all newborns, for whom both ante-natal ultrasound and fetal MRI were available, referred to our center for suspected bowel obstruction was performed. Examinations were reviewed blinded to the postnatal outcome. Key outcome measures included exact diagnosis and the existence of postoperative SBS. We evaluated the contribution of MRI in determining precise location and etiology of the bowel obstruction, dilatation of the proximal bowel loops, and assessment of the quality of the remaining distal bowel loops. RESULTS: Twenty-five newborns were included. There were 19 single obstructions and 6 complex forms (4 apple peel syndromes and 2 multiple atresias). MRI correctly identified the affected segment of the small bowel in 59.1% of the cases. MRI identified the mechanism of obstruction in 72% of cases. MRI reliably predicted an abnormal appearance of the bowel distal to the obstruction in 100% of the severe cases (3/3) and in 66.7% of complex forms (4/6). CONCLUSION: Our study suggests that fetal MRI, when done in addition to prenatal ultrasound, is contributory in the management of fetuses with suspected bowel obstruction. MRI may be particularly useful in determining the location and origin of the bowel obstruction and in assessing the quality of the bowel distal to the obstruction, which might assist in the prediction of SBS and more detailed prenatal counseling.

Contribution of magnetic resonance imaging to the prenatal diagnosis of common congenital vascular anomalies.

BACKGROUND: Screening ultrasound (US) has increased the detection of congenital vascular anomalies in utero. Complementary magnetic resonance imaging (MRI) may improve the diagnosis, but its real utility is still not well established. OBJECTIVES: We aimed to describe the imaging findings on prenatal US and MRI of the most frequent congenital vascular anomalies (lymphatic malformations and congenital hemangiomas) to assess the accuracy of prenatal US and MRI exams for diagnosis and to evaluate the relevance of the additional information obtained by complementary fetal MRI. MATERIALS AND METHODS: All confirmed postnatal congenital vascular anomalies detected in the last 10 years at 3 university hospitals were retrospectively identified. The prenatal diagnosis was compared with the final diagnosis for both methods and the clinical relevance of additional MRI information was evaluated. A second MRI in advanced pregnancy was performed in fetuses with lesions in a sensitive anatomical location and the clinical relevance of the additional information was evaluated. RESULTS: Twenty-four cases were included in the study, 20 lymphatic malformations and 4 hemangiomas. MRI slightly improved the diagnosis of lymphatic malformation, 85% vs. 80% at US, especially for abdominal lesions. Both methods had a low identification rate (25%) for tumors. MRI performed late in five fetuses with lymphatic malformation allowed optimized management at birth. CONCLUSION: MRI improves the diagnosis of congenital lymphatic malformations whereas hemangiomas remain difficult to identify in utero. The main role of MRI is to provide high-defined anatomical data to guide management at birth.

Assessment of BOLD response in the fetal lung.

OBJECTIVE: Assessment of lung development and maturity is of utmost importance in prenatal counseling. Blood oxygen level-dependent (BOLD) effect MRI was developed for functional evaluations of organs. To date, no data are available in fetal lungs and nothing is known about the existence of a BOLD effect in the lungs. The aim of our study was to evaluate if a BOLD response could be detected in fetal lungs. MATERIALS AND METHODS: From January 2014 to December 2016, 38 healthy pregnant women were prospectively enrolled. After a routine scan on a 1.5-T MRI device (normoxic period), maternal hyperoxia was induced for 5 min before the BOLD sequence (hyperoxic period). R2* was evaluated by fitting average intensity of the signal, both for normoxic (norm) and hyperoxic (hyper) periods. RESULTS: A significant BOLD response was observed after maternal hyperoxia in the lungs with a mean R2* decrease of 12.1 ± 2.5% (p < 0.001), in line with the placenta response with a mean R2* decrease of 19.2 ± 5.9% (p < 0.0001), confirming appropriate oxygen uptake. Conversely, no significant BOLD effect was observed for the brain nor the liver with a mean ∆R2* of 3.6 ± 3.1% (p = 0.64) and 2.8 ± 3.7% (p = 0.23). CONCLUSION: This study shows for the first time in human that a BOLD response can be observed in the normal fetal lung despite its prenatal "non-functional status." If confirmed in congenital lung and chest malformations, this property could be used in addition to the lung volume for a better prediction of postnatal respiratory status. KEY POINTS: • Blood oxygen level-dependent (BOLD) effect MRI was developed for functional evaluations of organs and could have interesting implications for the fetal organs. • Assessment of lung development is of utmost importance in prenatal counseling, but to date no data are available in fetal lungs. • BOLD response can be observed in the normal fetal lung opening the way to studies on fetus with pathological lungs.

Endometriosis and the Urinary Tract: From Diagnosis to Surgical Treatment.

We aim to describe the diagnosis and surgical management of urinary tract endometriosis (UTE). We detail current diagnostic tools, including advanced transvaginal ultrasound, magnetic resonance imaging, and surgical diagnostic tools such as cystourethroscopy. While discussing surgical treatment options, we emphasize the importance of an interdisciplinary team for complex cases that involve the urinary tract. While bladder deep endometriosis (DE) is more straightforward in its surgical treatment, ureteral DE requires a high level of surgical skill. Specialists should be aware of the important entity of UTE, due to the serious health implications for women. When UTE exists, it is important to work within an interdisciplinary radiological and surgical team.

Focal adenomyosis of the outer myometrium and deep infiltrating endometriosis severity.

OBJECTIVE: To determine whether the presence of focal adenomyosis of the outer myometrium (FAOM) at preoperative magnetic resonance imaging is associated with the severity of deep infiltrating endometriosis. DESIGN: Observational cross-sectional study involving 255 symptomatic deep infiltrating endometriosis patients. Comparisons were performed according to the presence of FAOM. SETTING: University hospital. PATIENT(S): Women with a preoperative magnetic resonance imaging and complete surgical exeresis of endometriotic lesions with histologically documented deep infiltrating endometriosis. INTERVENTION(S): Surgical management for deep infiltrating endometriosis. MAIN OUTCOME MEASURE(S): The presence of multiple deep infiltrating endometriosis lesions, the mean number and location of deep infiltrating endometriosis lesions, and the mean total revised American Society for Reproductive Medicine scores. RESULT(S): The prevalence of FAOM at preoperative magnetic resonance imaging in the 255 patients with deep infiltrating endometriosis was 56.5%. The mean number of deep infiltrating endometriosis lesions was significantly higher in the FAOM(+) group than in the FAOM(-) group: 3.5 ± 2.1 vs. 2.2 ± 1.5. The mean total revised American Society for Reproductive Medicine score was higher in case of FOAM coexisting with deep infiltrating endometriosis. After adjusting for confounding factors, the presence of FAOM was significantly associated with multiple deep lesions. CONCLUSION(S): FAOM was significantly associated with greater deep infiltrating endometriosis severity. This needs to be integrated into the management strategy. Furthermore, a pathogenic link between deep infiltrating endometriosis and FAOM cannot be excluded.

The use of image fusion in prenatal medicine.

Fusion imaging (FI), the simultaneous display of the same anatomical region using two imaging modalities, has been used in other areas of medicine for both diagnosis and guiding interventions. Examples include positron emission tomography-computed tomography (PET-CT) imaging in oncology and ultrasound-magnetic resonance imaging (US-MRI) fusion in biopsies of the prostate gland. The underlying principle is to take advantage of the complementary information in each modality to improve accuracy, be it diagnostic accuracy or targeting accuracy in biopsies. For example, PET-CT overlays the metabolic activity of lesions on the superb spatial and anatomical detail of CT. While the historical mainstay of fetal imaging has been ultrasound, advances in ultrafast MR imaging together with advances in fetal MRI over the past two decades, have resulted in the opportunity to explore fusion imaging in fetal medicine. We present an overview of the principles of US-MRI fusion imaging in prenatal medicine, report our local experience, and review the literature in this emerging area. We share our perspective on how FI can improve diagnostic confidence, be used as an educational tool, and potentially enhance guidance in certain fetal procedures.

Arterial Spin Labeling and Central Precocious Puberty.

PURPOSE: To evaluate a non-invasive method to assess the progressivity of idiopathic central precocious puberty (CPP) by quantifying perfusion of the pituitary stalk with arterial spin labeling (ASL) and using the gonadotropin-releasing hormone (GnRH) test as a reference test to define progressive CPP. METHODS: In a single center retrospective study, 52 consecutive patients, observed between October 2015 and April 2017 and referred with early signs of puberty, were evaluated using the GnRH test and cerebral magnetic resonance imaging (MRI). Patients with peripheral or non-idiopathic puberty were excluded. The distribution of perfusion values between patients with progressive and non-progressive CPP was compared using a nonparametric Mann-Whitney U­test. RESULTS: In this study 35 patients were included and 29 had progressive CPP. These patients displayed significantly higher cerebral blood flow (CBF) values than the 6 patients with non-progressive CPP (p = 0.006). The median CBF for patients with non-progressive and progressive CPP was 45.25 ml/min/100 g (interquartile range 36.9-54) vs. 65 ml/min/100 g (interquartile range 55.5-74.5), respectively. To determine if the CPP was progressive, the best CBF threshold was 55.5 ml/min/100 g with a sensitivity of 76%, a specificity of 83% and an accuracy of 77%. There were strong significant correlations between CBF and LH peak (r = 0.67, p < 0.001) and between CBF and LH/FSH peaks ratio [r = 0.71, p < 0.001] during the GnRH test. CONCLUSION: Arterial spin labelling (ASL) offers a novel tool to assess the progressivity of idiopathic CPP.

The use of fetal MRI for renal and urogenital tract anomalies.

Fetal anomalies are detected in approximately 2% of all fetuses and, among these, genitourinary tract abnormalities account for 30% to 50% of all structural anomalies present at birth. Although ultrasound remains the first line diagnostic modality, fetal MRI provides important additional structural and functional information, especially with the development of faster sequences and the use of functional sequences. The added value of MRI-based imaging is three-fold: (a) improvement of diagnostic accuracy by adequate morphological examination, (b) detection of additional anomalies, and (c) in addition, MRI has the potential to provide information regarding renal function. In this review, we describe the role of fetal MRI in the anatomical evaluation of renal and urogenital tract anomalies, and we also touch upon the contribution of functional MRI to the diagnostic workup of these conditions.

Magnetic resonance imaging presentation of deep infiltrating endometriosis nodules before and after pregnancy: A case series.

OBJECTIVE: To compare the magnetic resonance imaging (MRI) features of deep infiltrating endometriosis (DIE) lesions before and after pregnancy. DESIGN: Retrospective study. SETTING: A single French university tertiary referral hospital. PATIENTS: Twenty-one women without a prior history of surgery for endometriosis with a radiological diagnosis by MRI with two sets of examinations performed before and after pregnancy. INTERVENTIONS: The volumes of the lesions were compared using the same protocol before and after pregnancy based on MRI (1.5 T) examinations by a single experienced radiologist who is a referring practitioner for image-based diagnosis of endometriosis. MAIN OUTCOME MEASURE(S): The DIE lesion volume. MEASUREMENTS AND MAIN RESULTS: Between October 2012 and December 2016, a total of 21 patients (67 lesions) were included and compared before and after pregnancy. The mean time interval between the MRI before pregnancy and delivery was 19.6 ± 8.5 months (median: 17.6, IQR 13.5-25.2 months). The mean time interval between delivery and the MRI after pregnancy was 11.0 ± 6.4 months (median: 8.3, IQR 6-15.2 months). The mean overall DIE lesion volume by MRI was significantly higher before pregnancy compared to after pregnancy (2,552 ± 3,315 mm3 vs. 1,708 ± 3,266 mm3, respectively, p < 0.01). The mean volume by MRI of the largest lesion of each patient was significantly higher before pregnancy compared to after pregnancy (4,728 ± 4,776 mm3 vs. 3165 ± 5299 mm3; p < 0.01). CONCLUSION: Our data indicate a favorable impact of pregnancy on DIE lesion volumes as measured by MRI.

Fetal MRI findings in a retrospective cohort of 26 cases of prenatally diagnosed CHARGE syndrome individuals.

"CHARGE syndrome" (CS) is a multifaceted syndrome associated with a poor prognosis. The prenatal diagnosis remains challenging especially as the fetal anomalies that may evoke suspicion of CS are not comprehensively described. OBJECTIVE: This study aims to identify the anomalies in MRI with suspected CHARGE syndrome and to propose a possible standardization in the image-based prenatal diagnosis of CS. METHODS: This was a retrospective study of 26 fetuses who underwent MRI and had a confirmed diagnosis of CS, as proven by histopathological and/or neonatal examinations and/or the presence of the CHD7 gene mutation. RESULTS: The three most frequent MRI anomalies confirmed at histopathological and/or neonatal examinations were arhinencephaly in 100% (26 of 26), dysplasia of the semicircular canals agenesis (SCA) in 100% (24 of 24), and posterior fossa anomalies in 100% (22 of 22). Our study also revealed short petrous bones with a particular triangular shape in 24 of 24 cases of SCA. Other relevant findings included external ear anomalies in 36% (9 of 25), cleft lip and palate (9 of 9), ventriculomegaly (VMG) (6 of 6), short corpus callosum (3 of 3), and ocular asymmetry in 36.6% (4 of 11). CONCLUSION: Our study emphasizes the interest of fetal MRI in the diagnosis of CS with an adapted knowledge of semiology.

The Disease Phenotype of Adenomyosis-Affected Women Correlates With Specific Serum Cytokine Profiles.

BACKGROUND: Adenomyosis (ADE) is an enigmatic uterine disorder. Several types have been previously described: diffuse adenomyosis (DIF-ADE), focal adenomyosis (FOC-ADE), and association of focal and diffuse lesions (FOC/DIF-ADE). Abnormal immune phenomena have been described that may provide an understanding of the pathophysiology of adenomyosis. However, the immune imbalance in adenomyosis is however still poorly understood. OBJECTIVE: To compare serum cytokine profiles for the various adenomyosis phenotypes in adenomyosis versus disease-free women. MATERIALS AND METHODS: This cohort study included 80 women. Based on the magnetic resonance imaging (MRI) findings, the women were allocated to the ADE group (n = 60) and the control group (n = 20). The ADE group was further subdivided according to the phenotype: DIF-ADE, FOC-ADE, and FOC/DIF-ADE. For all of the women, serum cytokine levels were assayed by multiplex immunoassay. RESULTS: Serum levels of interleukin (IL) 23 (237.77 pg/mL ± 70.97 in the ADE-group versus 1855.04 ± 1411.33 in the control group, P = .019), IL25 (31.98 ± 8.54 vs 222.08 ± 170.90, respectively, P = .006), IL31 (10.13 ± 3.83 vs 91.51 ± 71.21, respectively, P = .034), IL33 (3.77 ± 1.23 vs 17.86 ± 11.49, respectively, P = .016), and IL17F (16.29 ± 2.35 vs 30.12 ± 8.29, respectively, P = .042) were significantly lower in the women with adenomyosis when compared to the controls In the FOC/DIF-ADE group, the serum levels of IL23, IL31, IL25, and IL33 were significantly lower when compared to the control group. CONCLUSION: Serum levels of IL23, IL31, IL25, and IL33 were lower in women exhibiting adenomyosis forms with associated diffuse and focal lesions when compared with controls. The pathogenesis of adenomyosis may be associated with an immunotolerant process that is more pronounced in associated FOC/DIF-ADE.

Placenta Imaging Workshop 2018 report: Multiscale and multimodal approaches.

The Centre for Medical Image Computing (CMIC) at University College London (UCL) hosted a two-day workshop on placenta imaging on April 12th and 13th 2018. The workshop consisted of 10 invited talks, 3 contributed talks, a poster session, a public interaction session and a panel discussion about the future direction of placental imaging. With approximately 50 placental researchers in attendance, the workshop was a platform for engineers, clinicians and medical experts in the field to network and exchange ideas. Attendees had the chance to explore over 20 posters with subjects ranging from the movement of blood within the placenta to the efficient segmentation of fetal MRI using deep learning tools. UCL public engagement specialists also presented a poster, encouraging attendees to learn more about how to engage patients and the public with their research, creating spaces for mutual learning and dialogue.
