RESUMO

A new carbazole-substituted bisterpyridine with pronounced delayed fluorescence is presented. While the molecular donor-acceptor-donor design suggests the origin of this to be thermally activated delayed fluorescence (TADF), results from various photophysical characterizations, OLED characteristics, temperature-dependent NMR spectroscopy, and DFT calculations all point against the involvement of triplet states. The molecule exhibits blue emission at about 440 nm with two or more fast decay channels in the lower nanosecond range in both solution and thin films. The delayed emission is proposed to be caused by rotational vibrational modes. We suggest that these results are generally applicable, especially for more complex molecules, and should be considered as alternative or competitive emissive relaxation pathways in the field of organic light emitting materials.

RESUMO

INTRODUCTION: Uterus transplantation is a novel surgical procedure that allows women with absolute uterine factor infertility to carry a pregnancy and give birth. While previous studies have explored the attitudes of women with absolute uterine factor infertility toward uterus transplantation, none have surveyed and compare their views with other groups of interest (Morris syndrome women, relatives of Morris syndrome and Rokitansky syndrome women, infertile women and women of childbearing age) in the same sociocultural setting. The objective of this study was to evaluate attitudes and insights regarding uterus transplantation among women with Rokitansky syndrome and other groups of interest. MATERIAL AND METHODS: We designed a cross-sectional study including five groups of women: women with Rokitansky syndrome, women with Morris syndrome, relatives of women with Morris and Rokitansky syndrome, infertile women, and childbearing-age women. We conducted an online survey through the REDCap platform. The link was distributed by mail, telephone and in hospital outpatient visits. Baseline demographic information was assessed and information regarding motherhood preferences, attitude toward uterus transplantation, preferred uterus graft and perception of risk of the procedure was collected. RESULTS: We obtained a total of 200 responses, with a mean participant age of 34.5 years (±9.8). Overall, 17.5% (n = 35) were women with Rokitansky syndrome, 5.5% (n = 11) Morris syndrome women, 21.5% (n = 43) infertile women, 26.5% (n = 53) relatives of Morris and Rokitansky syndrome women and 29% (n = 58) childbearing-age women. 71.5% of women with Rokitansky syndrome would undergo uterus transplantations ahead of adoption and surrogacy with no statistically significant differences found between groups. Overall, more than one-half (58%) would prefer deceased over living donor. CONCLUSIONS: The results of this survey indicate that uterus transplantation is desired by most women who would benefit from the procedure, including those with either Morris syndrome or absolute uterine factor infertility. This was also the preferred option for motherhood if absolute uterine factor infertility was diagnosed among surveyed infertility patients or women of childbearing age with no known reproductive difficulties. Overall, most respondents indicated a deceased donor was preferable to a living donor and that patients may not be sufficiently aware of potential risks of uterus transplantation, highlighting the importance of adequate counseling by medical providers.

RESUMO

INTRODUCTION: Alterations in microbiota composition have been implicated in a variety of human diseases. Patients with adenomyosis present immune dysregulation leading to a persistent chronic inflammatory response. In this context, the hypothesis that alterations in the microbiota may be involved in the pathogenesis of adenomyosis, by affecting the epigenetic, immunologic, and biochemical functions of the host, has recently been postulated. The aim of the present study was to compare the microbiota composition in the vagina, endometrium, and gut of individuals with and without adenomyosis. MATERIAL AND METHODS: Cross-sectional study including 38 adenomyosis patients and 46 controls, performed between September 2021 and October 2022 in a university hospital-based research center. The diagnosis of adenomyosis was based on sonographic criteria. Fecal, vaginal, and endometrial samples were collected. Study of the microbiota using 16S rRNA gene sequencing. RESULTS: Patients with adenomyosis exhibited a significant reduction in the gut microbial alpha diversity compared with healthy controls (Chao1 p = 0.012, Fisher p = 0.005, Observed species p = 0.005). Beta-diversity analysis showed significant differences in the compositions of both gut and vaginal microbiota between adenomyosis patients and the control group (Adonis p-value = 0.001; R2 = 0.03 and Adonis p-value = 0.034; R2 = 0.04 respectively). Specific bacterial taxa were found to be either overrepresented (Rhodospirillales, Ruminococcus gauvreauii group, Ruminococcaceae, and Actinomyces) or underrepresented in the gut and endometrial microbiota of adenomyosis patients compared with controls. Distinct microbiota profiles were identified among patients with internal and external adenomyosis phenotypes. CONCLUSIONS: The study revealed reduced gut microbiota diversity in adenomyosis patients, accompanied by distinct compositions in gut and vaginal microbiota compared with controls. Overrepresented or underrepresented bacterial taxa were noted in the gut and endometrial microbiota of adenomyosis patients, with variations in microbiota profiles among those with internal and external adenomyosis phenotypes. These findings suggest a potential association between microbiota and adenomyosis, indicating the need for further research to comprehensively understand the implications of these differences.

RESUMO

A systematic review and meta-analysis were performed to identify if there is a subset of patients with POI who are more likely to show follicular growth after ovarian fragmentation for follicular activation (OFFA) or in vitro activation (IVA). Five studies met inclusion criteria for meta-analysis with a total of 164 patients. Forty-three patients showed follicle development (26.21%). Of those, the pregnancy rate was 35.58% (11/43) and the live birth rate was 20.93% (9/43). Our meta-analysis showed that age was not associated with follicle growth. However, lower baseline FSH, lower duration of amenorrhea/diagnosis, and presence of follicles remaining in biopsy were statistically significant for follicle development. Patients with basal characteristics mentioned before may have more chances to show follicle growth after OFFA or IVA. Taking into account that approximately 20% of patients with follicle growth had live birth, these results are very promising. Given the overall certainty of evidence, future studies are needed to confirm said results.

RESUMO

OBJECTIVES: The number of susceptibility loci currently associated with vasculitis is lower than in other immune-mediated diseases due in part to small cohort sizes, a consequence of the low prevalence of vasculitides. This study aimed to identify new genetic risk loci for the main systemic vasculitides through a comprehensive analysis of their genetic overlap. METHODS: Genome-wide data from 8467 patients with any of the main forms of vasculitis and 29 795 healthy controls were meta-analysed using ASSET. Pleiotropic variants were functionally annotated and linked to their target genes. Prioritised genes were queried in DrugBank to identify potentially repositionable drugs for the treatment of vasculitis. RESULTS: Sixteen variants were independently associated with two or more vasculitides, 15 of them representing new shared risk loci. Two of these pleiotropic signals, located close to CTLA4 and CPLX1, emerged as novel genetic risk loci in vasculitis. Most of these polymorphisms appeared to affect vasculitis by regulating gene expression. In this regard, for some of these common signals, potential causal genes were prioritised based on functional annotation, including CTLA4, RNF145, IL12B, IL5, IRF1, IFNGR1, PTK2B, TRIM35, EGR2 and ETS2, each of which has key roles in inflammation. In addition, drug repositioning analysis showed that several drugs, including abatacept and ustekinumab, could be potentially repurposed in the management of the analysed vasculitides. CONCLUSIONS: We identified new shared risk loci with functional impact in vasculitis and pinpointed potential causal genes, some of which could represent promising targets for the treatment of vasculitis.

RESUMO

Stilbenes are phenolic compounds naturally synthesized as secondary metabolites by the shikimate pathway in plants. Research on them has increased in recent years due to their therapeutic potential as antioxidant, antimicrobial, anti-inflammatory, anticancer, cardioprotective and anti-obesity agents. Amongst them, resveratrol has attracted the most attention, although there are other natural and synthesized stilbenes with enhanced properties. However, stilbenes have some physicochemical and pharmacokinetic problems that need to be overcome before considering their applications. Human clinical evidence of their bioactivity is still controversial due to this fact and hence, exhaustive basis science on stilbenes is needed before applied science. This review gathers the main physicochemical and biological properties of natural stilbenes, establishes structure-activity relationships among them, emphasizing the current problems that limit their applications and presenting some promising approaches to overcome these issues: the encapsulation in different agents and the structural modification to obtain novel stilbenes with better features. The bioactivity of stilbenes should move from promising to evident.

RESUMO

A novel material with dual activity toward organophosphate (OP) poisoning, based on Zr-MOF-808 and neutral oxime RS69N, has been prepared. The hybrid material has a significant drug payload (5.2 ± 0.9 oxime to MOF-808 molar ratio) and shows a sustained oxime release in simulated physiological media, leading to the successful reactivation of OP-inhibited acetylcholinesterase. At the same time, the hybrid system presents an efficient and moderately fast removal rate of a toxic organophosphorus model compound (diisopropylfluorophosphate) from simulated physiological media (t1/2 = 183 min; 95% removal rate after 24 h).

RESUMO

STUDY OBJECTIVE: To compare the accuracy of preoperative ultrasound (US) in predicting the laparoscopically defined 2021 American Association of Gynecologic Laparoscopists (AAGL) Endometriosis Staging. DESIGN: Retrospective multicenter study of patients treated at 3 specialized endometriosis centers. SETTING: Three specialized endometriosis surgical centers in São Paulo (Brazil), Barcelona (Spain), and Avellino (Italy) participated. PATIENTS: A total of 878 patients aged 15 to 45 years with no history of pelvic malignancy underwent laparoscopic (LPS) treatment for suspected endometriosis. INTERVENTIONS: Retrospective review of preoperative transvaginal and transabdominal US (index test) assessed for endometriosis at all sites used in the 2021 AAGL Endometriosis Classification and classified patients into AAGL-US stages 1 to 4. Results were compared with reference-standard LPS (AAGL-LPS) staging. MEASUREMENTS AND MAIN RESULTS: The AAGL-US and AAGL-LPS stage were concordant in 586 cases (66.7%) (weighted kappa [WK] 0.759; intraclass correlation = 0.906), with the highest agreement observed in patients with no endometriosis (n = 70, 75.3% concordance), AAGL-LPS stage 1 (104, 50.7%) and stage 4 disease (358, 88.2%). Endometriosis was most accurately diagnosed in the rectum/sigmoid colon (WK 0.862), bladder (WK 0.911), and ovaries (WK 0.835/0.795 for right/left, respectively) and least accurately diagnosed at superficial peritoneal (WK 0.442), tubal (WK 0.391/0.363 for right/left, respectively), and retrocervical/uterosacral ligament (WK 0.656) sites. CONCLUSION: Sonographic estimation of the 2021 AAGL Endometriosis Staging is greatest in AAGL-LPS stages 1 and 4 and among patients with no endometriosis. US best identifies endometriosis of the ovaries, bladder, and bowel but is more limited for the tubes and superficial peritoneum.

RESUMO

There has been increasing interest in the study of new pathogenic mechanisms in endometriosis (END), including the coagulation/fibrinolysis system and its link with inflammation and tissue remodeling. It has been suggested that END patients, especially with deep-infiltrating (DE) forms, could present a hypercoagulable state revealing higher levels of proinflammatory and procoagulant markers, such as total circulating microparticles (cMPs) and cMP-TF (tissue factor), released by cells in response to damage, activation, or apoptosis. However, no previous study has assessed the effect of END hormonal treatments on cMP and cMP-TF levels. Therefore, the aim of this study was to evaluate the impact of these treatments on cMP and cMP-TF levels in DE patients. Three groups were compared: DE patients receiving a continuous combined oral contraceptive regimen (CCOCR) (n = 41), DE patients without CCOCR (n = 45), and a control group (n = 43). cMP and cMP-TF levels were evaluated in platelet-free plasma. A significant decrease in the total cMP levels was found in the DE group with CCOCR versus the group without CCOCR, reflecting a higher chronic inflammatory status in DE patients that decreased with the treatment. cMP-TF levels were higher in DE patients receiving CCOCR versus those not receiving CCOCR, suggesting that treatments containing estrogens play a predominant role in suppressing the inhibitory pathway of TF.

RESUMO

Celiac disease (CeD) is an immune-mediated disorder triggered by gluten ingestion that damages the small intestine. Although CeD has been associated with a higher risk for cancer, the role of CeD as a risk factor for specific malignancies, such as enteropathy-associated T-cell lymphoma (EATL), remains controversial. Using two-sample Mendelian randomization (2SMR) methods and the summarized results of large genome-wide association studies from public repositories, we addressed the causal relationship between CeD and eight different malignancies. Eleven non-HLA SNPs were selected as instrumental variables (IVs), and causality estimates were obtained using four 2SMR methods: random-effects inverse variance-weighted, weighted median estimation, MR-Egger regression, and MR pleiotropy residual sum and outlier (MR-PRESSO). We identified a significant causal relationship between CeD and mature T/NK cell lymphomas. Under a multivariate Mendelian randomization model, we observed that the causal effect of CeD was not dependent on other known lymphoma risk factors. We found that the most instrumental IV was located in the TAGAP locus, suggesting that aberrant T cell activation might be relevant in the T/NK cell malignization process. Our findings provide new insights into the connection between immune imbalance and the development of severe comorbidities, such as EATL, in patients with CeD.

RESUMO

ITGAM-ITGAX (rs11150612, rs11574637), VAV3 rs17019602, CARD9 rs4077515, DEFA (rs2738048, rs10086568), and HORMAD2 rs2412971 are mucosal immune defence polymorphisms, that have an impact on IgA production, described as risk loci for IgA nephropathy (IgAN). Since IgAN and Immunoglobulin-A vasculitis (IgAV) share molecular mechanisms, with the aberrant deposit of IgA1 being the main pathophysiologic feature of both entities, we assessed the potential influence of the seven abovementioned polymorphisms on IgAV pathogenesis. These seven variants were genotyped in 381 Caucasian IgAV patients and 997 matched healthy controls. No statistically significant differences were observed in the genotype and allele frequencies of these seven polymorphisms when the whole cohort of IgAV patients and those with nephritis were compared to controls. Similar genotype and allele frequencies of all polymorphisms were disclosed when IgAV patients were stratified according to the age at disease onset or the presence/absence of gastrointestinal or renal manifestations. Likewise, no ITGAM-ITGAX and DEFA haplotype differences were observed when the whole cohort of IgAV patients, along with those with nephritis and controls, as well as IgAV patients, stratified according to the abovementioned clinical characteristics, were compared. Our results suggest that mucosal immune defence polymorphisms do not represent novel genetic risk factors for IgAV pathogenesis.

RESUMO

The use of thermally activated delayed fluorescence (TADF) emitters and emitters that show preferential horizontal orientation of their transition dipole moment (TDM) are two emerging strategies to enhance the efficiency of OLEDs. We present the first example of a liquid crystalline multi-resonance TADF (MR-TADF) emitter, DiKTa-LC. The compound possesses a nematic liquid crystalline phase between 80 °C and 110 °C. Importantly, the TDM of the spin-coated film shows preferential horizontal orientation, with an anisotropy factor, a, of 0.28, which is preserved in doped poly(vinylcarbazole) films. Green-emitting (λEL =492 nm) solution-processed OLEDs based on DiKTa-LC showed an EQEmax of 13.6 %. We thus demonstrate for the first time how self-assembly of a liquid crystalline TADF emitter can lead to the so-far elusive control of the orientation of the transition dipole in solution-processed films, which will be of relevance for high-performance solution-processed OLEDs.

RESUMO

Betalains are the nitrogenous pigments that replace anthocyanins in the plant order Caryophyllales. Here, we describe unconventional decarboxylated betalains in quinoa (Chenopodium quinoa) grains. Decarboxylated betalains are derived from a previously unconsidered activity of the 4,5-DOPA-extradiol-dioxygenase enzyme (DODA), which has been identified as the key enzymatic step in the established biosynthetic pathway of betalains. Here, dopamine is fully characterized as an alternative substrate of the DODA enzyme able to yield an intermediate and structural unit of plant pigments: 6-decarboxy-betalamic acid, which is proposed and described. To characterize this activity, quinoa grains of different colors were analyzed in depth by chromatography, time-of-flight mass spectrometry, and reactions were performed in enzymatic assays and bioreactors. The enzymatic-chemical scheme proposed leads to an uncharacterized family of 6-decarboxylated betalains produced by a hitherto unknown enzymatic activity. All intermediate compounds as well as the final products of the dopamine-based biosynthetic pathway of pigments have been unambiguously determined and the reactions have been characterized from the enzymatic and functional perspectives. Results evidence a palette of molecules in quinoa grains of physiological relevance and which explain minor betalains described in plants of the Caryophyllales order. An entire family of betalains is anticipated.

RESUMO

Chenopodium quinoa (quinoa) is a pseudo-cereal that forms part of the cultural heritage of Andean countries, and its grains have high nutritional value and potential health benefits. Betalains are nitrogenous water-soluble pigments and bioactive molecules that contribute to these health-promoting properties. Betalains are restricted to plants of the order Caryophyllales, to which quinoa belongs. A new family of betalains has been discovered in the form of unconventional decarboxylated pigments. Here, we show that these pigments accumulate in ripening quinoa grains of fluorescent nature, and are putatively based on a dopamine-cleaving activity. This study describes for the first time the purification and molecular and functional characterization of a 4,5-dopamine extradiol dioxygenase enzyme from plants. It is a monomeric protein with a molecular mass of 34.5 kDa characterized by chromatography, electrophoresis, and time-of-flight mass spectrometry. We demonstrate that this key enzyme has a dual function in a square-shaped biosynthetic pathway towards the formation of both carboxylated and decarboxylated pigments. Enzyme kinetic properties are characterized for the production of 6-decarboxy-betalamic acid and 3,4-dihydroxy-l-phenylalanine-derived betalamic acid, the two structural units of plant pigment in nature. The profile of multiple betalains present in quinoa grains has been reproduced in one-pot bioreactors containing the novel enzyme and two competing substrates.

RESUMO

BACKGROUND: The quality of life of women with deep infiltrating endometriosis (DIE) is impaired and may improve with combined oral contraceptives (COCs). AIM: To compare the overall and sexual quality of life of patients diagnosed with DIE with or without associated adenomyosis (AD) with that of healthy controls and determine the influence of a COC containing 2 mg dienogest/30 µg ethinyl estradiol on these aspects. METHODS: We enrolled 42 women diagnosed with DIE; 31 diagnosed with DIE + AD by transvaginal ultrasound, and 39 non-AD/DIE controls. All patients were interviewed regarding pain symptoms (dysmenorrhea, dyspareunia, dyschezia, and dysuria), heavy menstrual bleeding using the Pictorial Blood Loss Assessment Chart, quality of life using the Short Form-36 questionnaire (SF-36), and sexual quality of life using the Sexual Quality of Life-Female questionnaire (SQOL-F) and the Brief Profile of Female Sexual Function (B-PFSF) before starting COCs and after 12 months of treatment. OUTCOMES: There was significant improvement in overall and sexual quality of life after treatment in DIE and DIE + AD patients. RESULTS: Non-AD/DIE controls showed significantly higher scores in the B-PFSF, the SQOL-F and the SF-36 questionnaires (P < .05) at baseline versus the other groups. DIE + AD patients showed poorer quality of sexual life and greater intensity in pain symptoms compared with DIE patients. After 12 months of treatment, there was a significant improvement in overall and sexual quality of life in the DIE and DIE + AD groups, with improvement in sexual quality of life being slightly greater in DIE + AD patients compared with DIE patients. Pain symptoms also decreased in both groups. CLINICAL IMPLICATIONS: Patients with DIE + AD showed greater impairment in overall and sexual quality of life compared with patients with isolated DIE which seems to improve with a COC containing 2 mg dienogest/30 µg ethinyl estradiol. STRENGTHS & LIMITATIONS: Strengths include the long-term follow up, assessment of the impact of two associated conditions, and administration of the same COC in all patients. Limitations include the relatively small sample size, and the fact that we did not assess the effectiveness of a flexible extended COC regimen containing 2 mg dienogest/30 µg ethinyl estradiol since the groups were different at baseline. CONCLUSION: Patients diagnosed with DIE with or without AD have a decreased quality of life which may improve with a COC containing 2 mg dienogest/30 µg ethinyl estradiol. Further research is needed to confirm our results. Alcalde AM, Martínez-Zamora MÁ, Gracia M, et al.

RESUMO

INTRODUCTION: Surgical treatment for stress urinary incontinence (SUI) with mid-urethral sling (MUS) is considered to have a high success rate. However, between 5% and 20% of MUS fail, with inadequate surgical implantation being a possible cause of SUI persistence or recurrence. Misplacement of a MUS can be determined by pelvic floor ultrasound (PF-US). The aim of this study was to investigate the role of PF-US in patients with persistent or recurrent urinary incontinence (UI) symptoms after MUS surgery for SUI with a midterm follow-up. MATERIALS AND METHODS: A historical cohort study including women undergoing MUS surgery for SUI between 2013 and 2015 was designed. The primary outcome was to correlate the sonographic parameters of MUS with SUI cure (negative International Continence Society-Uniform Cough Stress Test, Incontinence Questionnaire-Short Form < 5 points and no symptoms of SUI), at 5 years postsurgery. Secondary outcomes were changes of maximum urethral closure pressure (MUCP) and symptoms of urgency urinary incontinence (UUI) at 1 and 5 years after surgery. RESULTS: Eighty-seven patients (80 transobturator-MUS, 7 retropubic-MUS) were included. At 5 years all patients referred improvement of UI and objective cure of SUI was demonstrated in 81.2%. The MUS was sonographically correct in 67 (98.5%) of the 68 patients with cure of SUI. The MUS was considered incorrectly placed in only 4 (28.6%) of the 14 patients with noncured SUI. MUCP decreased from 61.9 to 48.8 cmH2 O at 5 years of follow-up (p < 0.01) and up to 53% of women had UUI symptoms after surgery, with a nonsignificant decrease compared to baseline. CONCLUSION: Patients cured of SUI had sonographically correct MUS by PF-US. Less than one-third of cases of SUI persistence or recurrence after MUS surgery could be explained by a sonographically incorrect sling. Low urethral resistance and/or UUI symptoms could help to explain the remaining failures. Complete functional and anatomic studies, including urodynamics and PF-US, should be performed before deciding on the next management strategy in patients with SUI persistence or recurrence after MUS.

RESUMO

Adenomyosis and endometriosis are similar gynecological diseases that decrease sexual quality of life and, in the case of endometriosis, satisfaction in couple relationships. This study aimed to assess sexual quality of life and couple satisfaction in women diagnosed with adenomyosis (AD) or deep infiltrating endometriosis (DIE). The study population included three groups of couples: one composed of 58 couples in which the woman was diagnosed with AD by transvaginal ultrasound (AD group), a second group comprising 55 couples in which the woman was diagnosed with isolated DIE by transvaginal ultrasound (DIE group), and a third group composed of 60 couples in which the women did not have AD or endometriosis (non-AD/DIE group). All women completed the Sexual Quality of Life-Female (SQOL-F) questionnaire, and all the couples completed the Dyadic Adjustment Scale (DAS). Sexual quality of life was significantly worse in women with AD or DIE compared with non-AD/DIE controls. Dyadic adjustment was significantly worse in the AD and DIE groups compared with the non-AD/DIE group. AD and DIE may impair quality of sexual life and couple relationships. Clinicians should be aware of this issue when treating women with AD or DIE.

RESUMO

INTRODUCTION AND HYPOTHESIS: We aimed to evaluate the results of a readjustable sling (Remeex® system) among a selected group of women with complex stress urinary incontinence (SUI) with sonographic hypomobile urethra and assessing failure-related risk factors. METHODS: Observational, longitudinal, prospective cohort study, including patients who underwent surgery with the Remeex® system. The primary outcome was a binary outcome in change of one level or more of the severity of urinary incontinence symptoms according to the intervals of the Incontinence Questionnaire-Short Form (ICIQ-UI-SF) score (mild, moderate, severe and very severe). Secondary outcomes were postsurgical complications, absolute ICIQ-UI-SF, 24-h pad weight test (24-h PT), urodynamic SUI and Patient Global Impression of Improvement (PGI-I) score to evaluate subjective success. RESULTS: Among 120 women included, after surgery we found a 70% subjective success rate, a 76.7% decrease of urinary incontinence severity and a mean reduction of the 24-h PT of 109.6 ± 291.4 g. Women with post-surgical decreased severity of incontinence had lower mean body mass index (BMI) and 24-h PT than those without incontinence severity changes with statistically significant differences (p = 0.028 and p = 0.027, respectively). A logistic regression model demonstrated that a 1-point increase of BMI increased the risk of persistence of incontinence severity after surgery by 19% (OR = 1.19; 95% CI: 1.01-1.41; p = 0.040), and an increase of 10 g in the pre-surgical 24-h PT represented a 3% rise of the aforementioned risk (OR = 1.03; 95% CI: 1.01-1.06; p = 0.034). CONCLUSIONS: In patients with complex SUI and sonographic hypomobile urethra, use of a readjustable sling (Remeex® system) led to improvement of SUI. Patients with a greater BMI and pre-surgical 24-h PT showed worse results after surgery.

RESUMO

OBJECTIVE: Evaluate antral follicle count measured after pituitary suppression (AFCaps) with a GnRH agonist as predictor of ovarian response and cumulative live birth (CLB). METHODS: This study is a large cohort analysis of retrospective data between January 2011 and September 2020 in a tertiary-care university hospital. All first initiated IVF/ICSI cycles in women under 43 years of age for whom AFCaps was registered in our database were included. To evaluate CLB rates (CLBRs), only finalized cycles were analyzed (at least one live birth and/or all embryos transferred), excluding PGT cycles and severe male factor requiring testicular sperm extraction. RESULTS: AFCaps showed a good predictive ability in predicting ovarian response to ovarian stimulation. Predicting poor response, AFCaps presented an area under the receiver-operating characteristic curve (AUCROC) of 0.85 (95% CI 0.83-0.87), for high response prediction, the AUCROC was 0.80 (95% confidence interval [CI] 0.77-0.83).Although AFCaps was statistically higher in patients who achieved at least one live birth (13.6 ± 6.05 vs. 9.79 ± 6.33) and CLBRs per started cycle significantly increase between AFCaps quartiles (15.9%, 36.2%, 45.1% and 52.9%) its ability to predict CLBR was modest, with an AUCROC of 0.67 (95% CI 0.65-0.69). CONCLUSIONS: Women undergoing their first IVF/ICSI cycle following a long agonist GnRH protocol can be counseled with AFCaps measurement about their probability of achieving poor/high response. Based on this marker physicians can personalize ovarian stimulation with the aim of optimizing ovarian response and minimizing its risks. However, AFCaps has failed to predict CLB per started IVF cycle as an isolated marker.

RESUMO

OBJECTIVES: To assess the postsurgical sonographic parameters of a readjustable sling (RAS) according to urinary incontinence (UI) symptoms after surgery and compare this RAS sonographic pattern with mid-urethral slings (MUS). METHODS: Observational, prospective multicenter study, including women undergoing stress urinary incontinence (SUI) surgery with RAS (Remeex®). The primary outcome was the association between UI symptoms and sonographic parameters measured by two-dimensional transperineal and high-frequency endovaginal ultrasound. We measured static parameters (bladder neck funneling, RAS position, symmetry, distance to the urethral lumen), and the movement of the sling on Valsalva. UI symptoms were measured with the postsurgical Incontinence Questionnaire-Short Form (ICIQ-UI-SF) questionnaire. We created two control groups including patients with transobturator-MUS (TOT-MUS) and retropubic-MUS (RT-MUS) to compare postsurgical sonographic parameters of RAS with MUS. RESULTS: Among the 55 women with RAS included, the postoperative ICIQ-UI-SF scores were significantly higher in patients with bladder neck funneling (15.0 (3.9) vs 10.6 (6.7); P = .020) and in those with discordant movement of RAS on Valsalva (14.6 (5.7) vs 10.3 (6.7); P = .045). Compared with the 109 women with TOT-MUS and the 55 with RT-MUS, RAS was more often located in the proximal urethra and farther from the urethral lumen. CONCLUSIONS: Postsurgical pelvic floor ultrasound demonstrated that in women with complex SUI and hypomobile urethra who underwent RAS (Remeex®) surgery, the presence of bladder neck funneling and discordant movement on Valsalva correlate with the persistence of UI symptoms. In these women, RAS is more often located in the proximal urethra and farther from the urethral lumen at rest in comparison with MUS.
