Abstract
BACKGROUND recently much studies evidenced the potential role of photo-biomodulation (PBM) in patients affected by Age-related Macular Degeneration (AMD). We designed a new wearable device for self-medication that employs the same broadband red light described in literature, but with extremely low irradiance. AIM to demonstrate the safety and effectiveness of low-fluence light stimulations emitted by a LED source with appropriate wavelengths through our new device in improving short-term visual function in patients affected by severe non neovascular AMD. MATERIALS AND METHODS we prospectively enrolled patients affected by severe non-neovascular AMD with a relative sparing of the foveal region. All the patients were randomly assigned in placebo or in treatment group. The treatment consisted of 10 sessions of 10-min each, using the new device comprised of micro-LEDs that emitted light onto an amorphous support assembled within Metallic eyeglasses. The placebo group blindly underwent the same number of PBM sessions with the micro-LED turned off. Before and after each placebo/treatment sessions all the patients received: optical coherence tomography (OCT), Best-Corrected Visual Acuity (BCVA) and Microperimetry (MP). RESULTS no significant differences in the anatomical parameters were observed in the two groups. The MP mean sensitivity and the central visual function both far and near significantly improved in the treated group (respectively p < 0.001, p < 0.001). CONCLUSIONS our pivotal demonstrated that the LED PBM delivered through our new device is a safe and effective tool for improving short-term visual function in patients affected by severe non-neovascular AMD.

Abstract
The transforming growth factor-β (TGF-β) family member activin A (hereafter Activin-A) is overexpressed in many cancer types, often correlating with cancer-associated cachexia and poor prognosis. Activin-A secretion by melanoma cells indirectly impedes CD8+ T cell-mediated anti-tumor immunity and promotes resistance to immunotherapies, even though Activin-A can be proinflammatory in other contexts. To identify underlying mechanisms, we here analyzed the effect of Activin-A on syngeneic grafts of Braf mutant YUMM3.3 mouse melanoma cells and on their microenvironment using single-cell RNA sequencing. We found that the Activin-A-induced immune evasion was accompanied by a proinflammatory interferon signature across multiple cell types, and that the associated increase in tumor growth depended at least in part on pernicious STING activity within the melanoma cells. Besides corroborating a role for proinflammatory signals in facilitating immune evasion, our results suggest that STING holds considerable potential as a therapeutic target to mitigate tumor-promoting Activin-A signaling at least in melanoma.

Abstract
Background We previously described the KINSSHIP syndrome, an autosomal dominant disorder associated with intellectual disability (ID), mesomelic dysplasia and horseshoe kidney,caused by de novo variants in the degron of AFF3. Mouse knock-ins and overexpression in zebrafish provided evidence for a dominant-negative (DN) mode-of-action, wherein an increased level of AFF3 resulted in pathological effects. Methods Evolutionary constraints suggest that other mode-of-inheritance could be at play. We challenged this hypothesis by screening ID cohorts for individuals with predicted-to-be deleterious variants in AFF3. We used both animal and cellular models to assess the deleteriousness of the identified variants. Results We identified an individual with a KINSSHIP-like phenotype carrying a de novo partial duplication of AFF3 further strengthening the hypothesis that an increased level of AFF3 is pathological. We also detected seventeen individuals displaying a milder syndrome with either heterozygous LoF or biallelic missense variants in AFF3. Consistent with semi-dominance, we discovered three patients with homozygous LoF and one compound heterozygote for a LoF and a missense variant, who presented more severe phenotypes than their heterozygous parents. Matching zebrafish knockdowns exhibit neurological defects that could be rescued by expressing human AFF3 mRNA, confirming their association with the ablation of aff3. Conversely, some of the human AFF3 mRNAs carrying missense variants identified in affected individuals did not complement. Overexpression of mutated AFF3 mRNAs in zebrafish embryos produced a significant increase of abnormal larvae compared to wild-type overexpression further demonstrating deleteriousness. To further assess the effect of AFF3 variation, we profiled the transcriptome of fibroblasts from affected individuals and engineered isogenic cells harboring +/+, DN/DN, LoF/+, LoF/LoF or DN/LoF AFF3 genotypes. The expression of more than a third of the AFF3 bound loci is modified in either the DN/DN or the LoF/LoF lines. While the same pathways are affected, only about one-third of the differentially expressed genes are common to these homozygote datasets, indicating that AFF3 LoF and DN variants largely modulate transcriptomes differently, e.g. the DNA repair pathway displayed opposite modulation. Conclusions Our results and the high pleiotropy shown by variation at this locus suggest that minute changes in AFF3 function are deleterious.

Abstract
For ethical, economical, and scientific reasons, animal experimentation, used to evaluate the potential neurotoxicity of chemicals before their release in the market, needs to be replaced by new approach methodologies. To illustrate the use of new approach methodologies, the human induced pluripotent stem cell-derived 3D model BrainSpheres was acutely (48 h) or repeatedly (7 days) exposed to amiodarone (0.625-15 µM), a lipophilic antiarrhythmic drug reported to have deleterious effects on the nervous system. Neurotoxicity was assessed using transcriptomics, the immunohistochemistry of cell type-specific markers, and real-time reverse transcription-polymerase chain reaction for various genes involved in the lipid metabolism. By integrating distribution kinetics modeling with neurotoxicity readouts, we show that the observed time- and concentration-dependent increase in the neurotoxic effects of amiodarone is driven by the cellular accumulation of amiodarone after repeated dosing. The development of a compartmental in vitro distribution kinetics model allowed us to predict the change in cell-associated concentrations in BrainSpheres with time and for different exposure scenarios. The results suggest that human cells are intrinsically more sensitive to amiodarone than rodent cells. Amiodarone-induced regulation of lipid metabolism genes was observed in brain cells for the first time. Astrocytes appeared to be the most sensitive human brain cell type in vitro. In conclusion, assessing readouts at different molecular levels after the repeat dosing of human induced pluripotent stem cell-derived BrainSpheres in combination with the compartmental modeling of in vitro kinetics provides a mechanistic means to assess neurotoxicity pathways and refine chemical safety assessment for humans.

Abstract
Bone marrow (BM) cellularity assessment is a crucial step in the evaluation of BM trephine biopsies for hematologic and nonhematologic disorders. Clinical assessment is based on a semiquantitative visual estimation of the hematopoietic and adipocytic components by hematopathologists, which does not provide quantitative information on other stromal compartments. In this study, we developed and validated MarrowQuant 2.0, an efficient, user-friendly digital hematopathology workflow integrated within QuPath software, which serves as BM quantifier for 5 mutually exclusive compartments (bone, hematopoietic, adipocytic, and interstitial/microvasculature areas and other) and derives the cellularity of human BM trephine biopsies. Instance segmentation of individual adipocytes is realized through the adaptation of the machine-learning-based algorithm StarDist. We calculated BM compartments and adipocyte size distributions of hematoxylin and eosin images obtained from 250 bone specimens, from control subjects and patients with acute myeloid leukemia or myelodysplastic syndrome, at diagnosis and follow-up, and measured the agreement of cellularity estimates by MarrowQuant 2.0 against visual scores from 4 hematopathologists. The algorithm was capable of robust BM compartment segmentation with an average mask accuracy of 86%, maximal for bone (99%), hematopoietic (92%), and adipocyte (98%) areas. MarrowQuant 2.0 cellularity score and hematopathologist estimations were highly correlated (R2 = 0.92-0.98, intraclass correlation coefficient [ICC] = 0.98; interobserver ICC = 0.96). BM compartment segmentation quantitatively confirmed the reciprocity of the hematopoietic and adipocytic compartments. MarrowQuant 2.0 performance was additionally tested for cellularity assessment of specimens prospectively collected from clinical routine diagnosis. After special consideration for the choice of the cellularity equation in specimens with expanded stroma, performance was similar in this setting (R2 = 0.86, n = 42). Thus, we conclude that these validation experiments establish MarrowQuant 2.0 as a reliable tool for BM cellularity assessment. We expect this workflow will serve as a clinical research tool to explore novel biomarkers related to BM stromal components and may contribute to further validation of future digitalized diagnostic hematopathology workstreams.

Abstract
More than 70% of human breast cancers (BCs) are estrogen receptor α-positive (ER+). A clinical challenge of ER+ BC is that they can recur decades after initial treatments. Mechanisms governing latent disease remain elusive due to lack of adequate in vivo models. We compare intraductal xenografts of ER+ and triple-negative (TN) BC cells and demonstrate that disseminated TNBC cells proliferate similarly as TNBC cells at the primary site whereas disseminated ER+ BC cells proliferate slower, they decrease CDH1 and increase ZEB1,2 expressions, and exhibit characteristics of epithelial-mesenchymal plasticity (EMP) and dormancy. Forced E-cadherin expression overcomes ER+ BC dormancy. Cytokine signalings are enriched in more active versus inactive disseminated tumour cells, suggesting microenvironmental triggers for awakening. We conclude that intraductal xenografts model ER + BC dormancy and reveal that EMP is essential for the generation of a dormant cell state and that targeting exit from EMP has therapeutic potential.

The mRNA expression of genes involved in embryo implantation (HOXA10, HOXA11, BTEB1 and LIF) does not change in patients with and without CE.
What is known already
CE is an inflammatory disorder of the endometrium with a detrimental effect on embryo implantation and its prevalence in women with repeated implantation failure (RIF) is up to 30%. During the implantation window, the expression of some genes plays a key role in determining the success of embryo implantation. The homeobox genes HOXA10, HOXA11 and the basic transcriptional element binding protein 1 (BTEB1) gene are essential for endometrial cells growth regulation and for embryonic development and the leukaemia inhibitory factor (LIF) has a role in the embryo–endometrium interaction.
Study design, size, duration
A single centre-prospective case-control study was conducted at the Women’s and Children’s Health Department at Padua University, on infertile women with RIF from June 2020 to November 2021. 29 women with RIF were prospectively enrolled.
Participants/materials, setting, methods
An endometrial biopsy using a Novak curette was performed for each patient and the obtained tissue samples were divided in two aliquots, one for immunohistochemistry for histological examination (endometrial dating and CE diagnosis) and one for RNA extraction and gene expression analysis that has been performed using RT-PCR. Sample of patients with and without CE were compared using non-parametric Mann–Whitney U-test. A p-value <.05 was considered as statistically significant.
Main results and the role of chance
Enrolled women were divided in two groups according to the histological diagnosis of CE: 13 patients with CE, 16 without CE. In all samples, appropriate histological dating (WOI) was evaluated according to Noyes criteria. After the comparison of all investigated genes (HOXA10, HOXA11, BTEB1 and LIF), no significant difference in mRNA expression was detected between women with and without CE (p value >.05). In the literature, defective endometrial expression of HOXA10, HOXA11 and LIF genes has been associated with abnormal implantation and the reduced expression of BTEB1 gene results in subfertility and progesterone resistance. Although the negative role of CE in altering embryo implantation is known, our results suggest that the CE has no effect on the expression of HOXA10, HOXA11, BTEB1 and LIF genes. Probably the detrimental effect of CE on embryo implantation does not act through HOXA10, HOXA11, BTEB1 and LIF gene expression.
Limitations, reasons for caution
This is a non-randomized observational study with a limited number of patients. Further studies are needed to confirm our data with immunohistochemistry evaluation to define the protein expression levels of the investigated genes.
Wider implications of the findings
Understanding the pathogenic mechanism of CE on endometrial receptivity is crucial for identifying markers that best correlate with possible implantation failure and for identifying the appropriate therapy to treat the disease and restore the embryo implantation capacity.

Abstract
Abstract
Study question
Does adjuvant therapy after frozen-thawed embryo-transfer (FRET) with CardioAspirin and Prednisone enhance clinical pregnancy rate (CPR) and live birth rate (LBR)?
Summary answer
Adjuvant therapy enhanced CPR and LBR in study-group. A significant correlation was found confronting blastocyst FRET in study-group versus controls.
What is known already
Embryo implantation is a rate-limiting step of FRET cycles. It’s a complex process resulting from a balance between inflammation pathways and maternal immune tolerance. Low-dose aspirin unlocks Prostaglandin-F2 synthesis by Cyclooxygenase–1, thus increasing uterine vascular permeability and attachment reaction while reducing vasoconstriction. Pregnancy results from a balance between helper and regulatory T-cells (Treg), the latter protect the embryo from maternal immune attack. Treg cells’ immunosuppressive function is pivotal in pregnancy establishment. Prednisone increases the proportion of Treg cells thus inhibiting inflammation. Many therapy schedules for implantation enhancement are currently used worldwide, although there is no consistent shared evidence.
Study design, size, duration
Retrospective cohort-control study including 237 subjects who underwent FRET after artificial endometrial-preparation from January 2018 to March 2020. Estrogenic stimulation was either oral or transdermic. The study-group received luteal support (vaginal Progesterone 600 mg/die) and adjuvant therapy (CardioAspirin and Prednisone 25–5 mg); the control-group received luteal support only. Pregnancy test (PT) was scheduled 10–14 days post-transfer (blastocysts or cleavage stage embryos). Second PT and ultrasound were performed 7 days later if the first was positive.
Participants/materials, setting, methods
Patients referred to Padua University Hospital’s Human Reproduction Pathophysiology Unit. Exclusion criteria: >50/<18 years, fresh embryo-transfer cycles, oocyte-thawing cycles, natural/natural-modified cycles. Male factor was the prevalent fertility issue. Single embryo-transfer was performed in both groups. Mean endometrial thickness was 9 mm trilaminar in both groups. Statistical analysis were carried out using JMP Pro 14 software. Categorical variables were analyzed using Chi-square test or Fisher’s exact test where appropriate.
Main results and the role of chance
In the study-group, 87 subjects were given luteal support and adjuvant therapy, while in the control-group, 150 subjects received luteal support only. Groups were homogeneous for age, number of embryos transferred, endometrial thickness, endometrial features (trilaminarity) and fertilization tecniques (108 IVF/ 127 ICSI). CPR and LBR were significantly higher in the study-group. CPR was 31.4% in study-group versus 14.8% in controls (p = 0.002), LBR was 27.4% in study-group versus 11.6% in controls (p = 0.002). Since heterogeneity between groups was found regarding the type of embryo transferred (55.3% cleavage-stage versus 44.7% blastocyst, p < 0.01), the groups were split analyzed basing upon the type if embryo transferred. In the cleavage-stage FRET condition no relevant correlation was found between groups. However in blastocyst-FRET group CPR (34.5% study-group versus 18% controls, p = 0.04) and LBR (30.9% study-group versus 12% controls, p = 0.017) were significantly higher in the study-group, thus showing that adjuvant therapy could improve CPR and LBR.
Limitations, reasons for caution
Limited sample size negatively impacts the study’s power. It would be appropriate to expand the sample to obtain more reliable results.
Wider implications of the findings: Although no unanimous consent exists for tout-court adjuvant therapy administration, scientific literature shows that such therapy can help patients with repeated implantation failures or anti-nuclear-antibodies positivity. Assuming that a single-therapy-regimen could perfectly fit all patients is not realistic. We have to move towards patient-tailored adjuvant therapy thinking.

Abstract
Abstract
Study question
How does the septate uterus and his metroplasty influence pregnancy rate (PR), live birth rate (LBR), spontaneous abortion rates (SA) and preterm labour rates (PL)?
Summary answer
Uterine septum is associated with a poor reproductive outcome. Metroplasty reduce the rate of SA but non-conclusive evidence can be extrapolated about PR and PL.
What is known already
Different studies evaluated the correlation between uterine septum and reproductive outcomes. On one hand, studies reported its association with poor obstetrics outcomes. On the other hand, recent studies raised doubts about the effectiveness of septum metroplasty to improve reproductive outcomes, although recent position papers continue to propose metroplasty in patients with a septate uterus and a history of infertility or miscarriages. Debate is still ongoing on reproductive outcomes of uterine septum on infertile patients and especially on patients with recurrent miscarriage, leading to an unanswered question whether or not these women should be treated.
Study design, size, duration
Systematic review and meta-analysis of published studies that evaluated the clinical impact of uterine septum and its metroplasty on reproductive and obstetrics outcomes. The meta-analysis included study with infertile patients or patients with a history of recurrent miscarriage.
Searches were conducted using the following search terms: uterine septum, septate uterus, metroplasty, pregnancy rate, live birth rate, spontaneous miscarriage, infertility, preterm delivery. Primary outcomes were PR and LBR. Secondary outcomes were SA and PL.
Participants/materials, setting, methods
The meta-analysis was written following the PRISMA guidelines. Fifty-nine full-text articles were preselected based on title and abstract. Endpoints were evaluated in three subgroups: 1) infertile/recurrent miscarriage patients with septum versus no septum 2) infertile/recurrent miscarriage patients with treated versus untreated septum 3) infertile/recurrent miscarriage patients before-after septum removal. Odds-ratios (OR) with 95% confidence intervals (CI) were calculated for outcome measures. Random-effect meta-analysis was performed and a p-value less than 0.05 was considered statistically significant.
Main results and the role of chance
Data from 37 articles were extracted. In the first subgroup (10 studies), a lower PR and LBR were associated with septate uterus vs. controls, respectively (OR 0.39, 95% CI 0.26 to 0.58; p < 0.000; low-heterogeneity and OR 0.21, 95% CI 0.12 to 0.39; p < 0.0001; small-heterogeneity) and a higher proportion of SA and PL was associated with septate uterus vs. controls, respectively (OR 4.17, 95% CI 2.83 to 6.15; p < 0.000; moderate-heterogeneity and OR 2.18, 95% CI 1.27 to 3.76; p = 0.005; low-heterogeneity). In the second subgroup (8 studies), PR and PL were not different in removed vs. unremoved septum, respectively (OR 1.10, 95% CI 0.49 to 2.49; p = 0.82; moderate heterogeneity and OR 0.44, 95% CI 0.18 to 1.08; p = 0.08;low-heterogeneity) and a lower proportion of SA was associated with removed vs. unremoved septum (OR 0.40, 95% CI 0.17 to 0.95; p = 0.001; substantial-heterogeneity). In the third subgroup (19 studies), the proportion of LBR was higher after the removal of septum (OR 49.58, 95% CI 29.93 to 82.13; p < 0.0001; moderate-heterogeneity) and the proportion of SA and PL was lower after the removal of septum, respectively (OR 0.02, 95% CI 0.02 to 0.04; p < 0.000; moderate-heterogeneity and OR 0.05, 95% CI 0.03 to 0.08; p = <0.000; low-heterogeneity).
Limitations, reasons for caution
The present meta-analysis is limited by the observational design of included studies because, in literature, there are no prospective randomized controlled trials (RCTs). In the second and third subgroup of analysis clinical heterogeneity within and between studies represents another limitation.
Wider implications of the findings
The results of this meta-analysis confirm the detrimental effect of uterine septum on PR, LBR, SA and PL. Its treatment seems to reduce the rate of SA. Metroplasty should still be considered as good clinical practice in patients with a history of infertility and recurrent abortion.

Abstract
Abstract
Study question
TSH blood levels play a role in terms of ovarian stimulation and pregnancy? Do we need to treat patients with TSH out of range?
Summary answer
Euthyroid patients with negative autoantibodies during COS should not be treated even if basal TSH is higher than 2.5 U/L
What is known already
Abnormal thyroid function is associated with adverse pregnancy outcomes, being essential during embryo implantation and early pregnancy. TSH receptors can be found in endometrial and ovarian tissues and during controlled ovarian stimulation TSH levels suffer modifications because of hyperestrogenemia. Subclinical hypothyroidism is defined as a TSH level greater than 4.5 mIU/L with normal FT4 levels. It is controversial whether or not to use first-trimester pregnancy and infertility thresholds for upper limit of 2.5 mIU/L TSH. However, neither American Thyroid Association nor the American Society Reproductive Medicine recommendations have clearly defined how infertile patients need to be treated.
Study design, size, duration
Between April 2016 and December 2019, we performed a retrospective observational study at the University Hospital of Padua, including patients who underwent IVF/ICSI treatments. We included patients with idiopathic or tubal infertility or with poor ovarian reserve, in presence of basal TSH≤ 4,5 U/L and negative anti-TPO Ab and anti-Tg Ab. Exclusion criteria were severe male factor, TSH<0,2 or > 4,5 U/L, BMI higher than 30, oncologic patients, uterine disease.
Participants/materials, setting, methods
We enrolled a total of 389 patients. We checked TSH blood levels on the day before starting stimulation (T0). We divided our patients according to TSH level < 2,5U/L (group A) or ≥ 2,5U/L (group B). We then checked TSH on the day of hCG trigger (ThCG). Delta TSH (ThCG-T0) was calculated and correlated to endometrial thickness, number of occytes retrieved, embryos obtained and frozen, Clinical Pregnancy Rate (CPR) and Live Birth Rate (LBR).
Main results and the role of chance
Group A (251) and group B (138) were homogeneous for age, body mass index, AMH levels, antral follicular count. Short ovarian stimulation cycle with GnRH antagonist and long cycle with GnRH agonist proportions were similar in both groups. Also, FSH recombinant and hMG gonadotropin use and total amount were similar for the two groups. No statistically significant difference was found between the groups in terms of endometrial thickness, follicles greater than 14 mm as medium diameter, number of oocytes retrieved, number of mature oocytes (MII), embryos obtained, number of embryos cryopreserved, CPR and LBR. However, when considering the Delta TSH, we found possible correlations in group A. In particular, the number of oocytes retrieved was higher in Delta TSH positive (3.4±2.2) rather than in Delta negative women (2.6±1.7) with a p value of 0.002. Moreover, mature oocytes (MII) were retrieved more frequently in Delta TSH positive (5.7±3.8) rather than in Delta negative women (4.5±3) with a p value of 0.008. Group B Delta TSH did not show any possible statistically significant correlations.
Limitations, reasons for caution
This is a retrospective study and results must be confirmed on a well-designed randomized controlled study. Moreover, since we use strict eligibility criteria, we enrolled few patients. Correlations must be considered with caution since the role of TSH is under study, especially when considering LBR outcome.
Wider implications of the findings: Our results are congruent with previous studies. In particular, we suggest not to treat patients with TSH levels on range (between 0.2mIU/L and 4.5 mIU/L). TSH increase during COS in euthyroid patients could be interpreted as a positive physiological response and it is associate with better COS outcomes.

Abstract
One of the hallmarks of COVID-19 is the cytokine storm that provokes primarily pneumonia followed by systemic inflammation. Emerging evidence has identified a potential link between elevated interleukin-17A (IL-17A) levels and disease severity and progression. Considering that per se, IL-17A can activate several inflammatory pathways, it is plausible to hypothesize an involvement of this cytokine in COVID-19 clinical outcomes. Thus, IL-17A could represent a marker of disease progression and/or a target to develop therapeutic strategies. This hypothesis paper aims to propose this "unique" cytokine as a silent amplifier of the COVID-19 immune response and (potentially) related therapy.

Abstract
Hormonal contraception exposes women to synthetic progesterone receptor (PR) agonists, progestins, and transiently increases breast cancer risk. How progesterone and progestins affect the breast epithelium is poorly understood because we lack adequate models to study this. We hypothesized that individual progestins differentially affect breast epithelial cell proliferation and hence breast cancer risk. Using mouse mammary tissue ex vivo, we show that testosterone-related progestins induce the PR target and mediator of PR signaling-induced cell proliferation receptor activator of NF-κB ligand (Rankl), whereas progestins with anti-androgenic properties in reporter assays do not. We develop intraductal xenografts of human breast epithelial cells from 36 women, show they remain hormone-responsive and that progesterone and the androgenic progestins, desogestrel, gestodene, and levonorgestrel, promote proliferation but the anti-androgenic, chlormadinone, and cyproterone acetate, do not. Prolonged exposure to androgenic progestins elicits hyperproliferation with cytologic changes. Androgen receptor inhibition interferes with PR agonist- and levonorgestrel-induced RANKL expression and reduces levonorgestrel-driven cell proliferation. Thus, different progestins have distinct biological activities in the breast epithelium to be considered for more informed choices in hormonal contraception.

Abstract
Abstract
Invasive lobular carcinoma (ILC) is the most frequent special histological subtype of breast cancer, typically characterized by loss of E-cadherin. It has clinical features distinct from other estrogen receptor-positive (ER+) breast cancers but the molecular mechanisms underlying its characteristic biology are poorly understood because we lack experimental models to study them. By xenografting lobular cells to the milk ducts, we recapitulate the human disease, including invasion and metastasis to clinically relevant organs. Using patient-derived intraductal xenografts from lobular and non-lobular ER+ HER2- tumors to compare global gene expression we identify extracellular matrix modulation as a lobular carcinoma cell-intrinsic trait. Analysis of TCGA patient datasets shows matrisome signature is enriched in lobular carcinomas with overexpression of elastin, collagens, and the collagen modifying enzyme LOXL1. Pharmacological treatment and silencing of LOXL1 expression decrease tumor growth, invasion, and metastasis by disrupting ECM structure resulting in decreased ER signaling. We conclude that LOXL1 inhibition is a promising therapeutic strategy for ILC. This is the first study of a hormone-responsive ER+ preclinical lobular model that mimics their clinical counterparts and opens opportunities for the development and evaluation of therapies.

Abstract
Vulvovaginal pathology impairs the quality of life of both women in menopause and those who are not. Different therapies have been proposed, mainly related to estrogen therapy in postmenopausal women. However, some contraindications limit its use, and different moisturizers or lubricants have been tested. Hyaluronic acid is a promising and widely used vaginal medical treatment with a moisturizing action and appears to provide a solution. For this reason, we performed a systematic review of the literature. We searched for original articles without date restriction until 30 April 2020. We included all clinical trials which administered local hyaluronic acid in the vulva or vagina. Only English studies and those performed in humans were eligible. Seventeen original studies were included in the review (from randomized controlled trials to longitudinal studies). Hyaluronic acid was generally found to be effective in improving vulvovaginal symptoms (dyspareunia, itching, burning, dryness) and signs (bleeding, atrophy, vaginal pH). In conclusion, hyaluronic acid has the properties to be an efficient moisturizer for women suffering from vulvovaginal atrophy who have contraindications for estrogen therapy and for vulvovaginal signs and symptoms affecting sexual well-being. However, a well-designed randomized controlled trial is needed in order to clarify its efficacy and safety profile.

Abstract
Invasive lobular carcinoma (ILC) is the most frequent special histological subtype of breast cancer, typically characterized by loss of E-cadherin. It has clinical features distinct from other estrogen receptor-positive (ER+ ) breast cancers but the molecular mechanisms underlying its characteristic biology are poorly understood because we lack experimental models to study them. Here, we recapitulate the human disease, including its metastatic pattern, by grafting ILC-derived breast cancer cell lines, SUM-44 PE and MDA-MB-134-VI cells, into the mouse milk ducts. Using patient-derived intraductal xenografts from lobular and non-lobular ER+ HER2- tumors to compare global gene expression, we identify extracellular matrix modulation as a lobular carcinoma cell-intrinsic trait. Analysis of TCGA patient datasets shows matrisome signature is enriched in lobular carcinomas with overexpression of elastin, collagens, and the collagen modifying enzyme LOXL1. Treatment with the pan LOX inhibitor BAPN and silencing of LOXL1 expression decrease tumor growth, invasion, and metastasis by disrupting ECM structure resulting in decreased ER signaling. We conclude that LOXL1 inhibition is a promising therapeutic strategy for ILC.

Abstract
BACKGROUND Energy drinks (ED) are popular among young people despite evidence of associated health risks. Research into the prevalence and pattern of ED intake among young people is sparse. The present study investigates the prevalence and pattern of ED intake among a large sample of adolescents, including how many consume them, how often, for what reasons and in what contexts. METHODS In 2018, all students in grades 7-12 attending 25 randomly selected Western Australian schools were invited to complete an online self-report survey about EDs. RESULTS Of the 3688 respondents, 51.2% reported consuming an ED. Of these 'ever consumers', 23.4% drank them monthly, 19.2% weekly and 2% every day. The average age of first intake was 10.7 years. One-fifth (19.7%) of 'ever consumers' reported consuming more than two EDs in 1 day. Reasons for ED use included taste, to boost energy levels, sport performance and studying. CONCLUSIONS The findings add to limited international evidence about adolescent ED use and provide valuable information to help ensure interventions to reduce intake address the underlying reasons and contexts of ED consumption.

Abstract
The Eukaryotic Promoter Database (EPD), available online at https://epd.epfl.ch, provides accurate transcription start site (TSS) information for promoters of 15 model organisms plus corresponding functional genomics data that can be viewed in a genome browser, queried or analyzed via web interfaces, or exported in standard formats (FASTA, BED, CSV) for subsequent analysis with other tools. Recent work has focused on the improvement of the EPD promoter viewers, which use the UCSC Genome Browser as visualization platform. Thousands of high-resolution tracks for CAGE, ChIP-seq and similar data have been generated and organized into public track hubs. Customized, reproducible promoter views, combining EPD-supplied tracks with native UCSC Genome Browser tracks, can be accessed from the organism summary pages or from individual promoter entries. Moreover, thanks to recent improvements and stabilization of ncRNA gene catalogs, we were able to release promoter collections for certain classes of ncRNAs from human and mouse. Furthermore, we developed automatic computational protocols to assign orphan TSS peaks to downstream genes based on paired-end (RAMPAGE) TSS mapping data, which enabled us to add nearly 9000 new entries to the human promoter collection. Since our last article in this journal, EPD was extended to five more model organisms: rhesus monkey, rat, dog, chicken and Plasmodium falciparum.

Abstract
BACKGROUND Positional weight matrix (PWM) is a de facto standard model to describe transcription factor (TF) DNA binding specificities. PWMs inferred from in vivo or in vitro data are stored in many databases and used in a plethora of biological applications. This calls for comprehensive benchmarking of public PWM models with large experimental reference sets. RESULTS Here we report results from all-against-all benchmarking of PWM models for DNA binding sites of human TFs on a large compilation of in vitro (HT-SELEX, PBM) and in vivo (ChIP-seq) binding data. We observe that the best performing PWM for a given TF often belongs to another TF, usually from the same family. Occasionally, binding specificity is correlated with the structural class of the DNA binding domain, indicated by good cross-family performance measures. Benchmarking-based selection of family-representative motifs is more effective than motif clustering-based approaches. Overall, there is good agreement between in vitro and in vivo performance measures. However, for some in vivo experiments, the best performing PWM is assigned to an unrelated TF, indicating a binding mode involving protein-protein cooperativity. CONCLUSIONS In an all-against-all setting, we compute more than 18 million performance measure values for different PWM-experiment combinations and offer these results as a public resource to the research community. The benchmarking protocols are provided via a web interface and as docker images. The methods and results from this study may help others make better use of public TF specificity models, as well as public TF binding data sets.

Abstract
Estrogens and progesterone control breast development and carcinogenesis via their cognate receptors expressed in a subset of luminal cells in the mammary epithelium. How they control the extracellular matrix, important to breast physiology and tumorigenesis, remains unclear. Here we report that both hormones induce the secreted protease Adamts18 in myoepithelial cells by controlling Wnt4 expression with consequent paracrine canonical Wnt signaling activation. Adamts18 is required for stem cell activation, has multiple binding partners in the basement membrane and interacts genetically with the basal membrane-specific proteoglycan, Col18a1, pointing to the basement membrane as part of the stem cell niche. In vitro, ADAMTS18 cleaves fibronectin; in vivo, Adamts18 deletion causes increased collagen deposition during puberty, which results in impaired Hippo signaling and reduced Fgfr2 expression both of which control stem cell function. Thus, Adamts18 links luminal hormone receptor signaling to basement membrane remodeling and stem cell activation. How hormonal signaling in the mammary epithelium controls the surrounding extracellular matrix is unclear. Here, the authors show that a secreted protease, Adamts18, induced by upstream estrogen-progesterone activated Wnt4 in myoepithelial cells, remodels the basement membrane and contributes to mammary epithelial stemness.

Abstract
Parkinson disease (PD) is characterized by a pivotal progressive loss of substantia nigra dopaminergic neurons and aggregation of α-synuclein protein encoded by the SNCA gene. Genome-wide association studies identified almost 100 sequence variants linked to PD in SNCA. However, the consequences of this genetic variability are rather unclear. Herein, our analysis on selective single nucleotide polymorphisms (SNPs) which are highly associated with the PD susceptibility revealed that several SNP sites attribute to the nucleosomes and overlay with bivalent regions poised to adopt either active or repressed chromatin states. We also identified large number of transcription factor (TF) binding sites associated with these variants. In addition, we located two docking sites in the intron-1 methylation prone region of SNCA which are required for the putative interactions with DNMT1. Taken together, our analysis reflects an additional layer of epigenomic contribution for the regulation of the SNCA gene in PD.

Abstract
Studying the genetic basis of gene expression and chromatin organization is key to characterizing the effect of genetic variability on the function and structure of the human genome. Here we unravel how genetic variation perturbs gene regulation using a dataset combining activity of regulatory elements, gene expression, and genetic variants across 317 individuals and two cell types. We show that variability in regulatory activity is structured at the intra- and interchromosomal levels within 12,583 cis-regulatory domains and 30 trans-regulatory hubs that highly reflect the local (that is, topologically associating domains) and global (that is, open and closed chromatin compartments) nuclear chromatin organization. These structures delimit cell type-specific regulatory networks that control gene expression and coexpression and mediate the genetic effects of cis- and trans-acting regulatory variants on genes.

Abstract
Several studies have compared the effectiveness of corifollitropin alfa versus daily gonadotropins in poor ovarian responders (PORs) undergoing controlled ovarian stimulation (COS), showing conflicting results in terms of IVF outcomes. Given the heterogeneity of patients included in the classification of POR according to 'Bologna criteria', the aim of this study was to evaluate the impact of corifollitropin alfa in two different categories of POR distinguished according to patients' antral follicle count (AFC). We retrospectively evaluated 104 infertile POR, split into two groups according to AFC (Group A ≤ 5; Group B > 5) and subgroups according to the ovarian stimulation regimen (corifollitropin alfa plus daily gonadotropins (Subgroup 1) versus daily gonadotropins alone (Subgroup 2)). Outcome measures were total oocytes, MII oocytes, total embryos, follicular output rate (FORT), implantation rate (IR), clinical pregnancy rate (CPR), miscarriage rate (MR), and live birth rate (LBR). Subgroup A1 experienced a lower number of total oocytes, MII oocytes, total embryos, and FORT (p < .05) in comparison to Subgroup A2, while no difference was found when comparing Subgroups B1 and B2. No difference was found between subgroups even in terms of IR, CPR, MR, and LBR. In conclusion, corifollitropin alfa may be as effective as daily gonadotropins in POR with AFC > 5 undergoing COS, while it might be inferior to daily gonadotropins in POR with AFC ≤ 5.

Abstract
The Mass Genome Annotation (MGA) repository is a resource designed to store published next generation sequencing data and other genome annotation data (such as gene start sites, SNPs, etc.) in a completely standardised format. Each sample has undergone local processing in order the meet the strict MGA format requirements. The original data source, the reformatting procedure and the biological characteristics of the samples are described in an accompanying documentation file manually edited by data curators. 10 model organisms are currently represented: Homo sapiens, Mus musculus, Danio rerio, Drosophila melanogaster, Apis mellifera, Caenorhabditis elegans, Arabidopsis thaliana, Zea mays, Saccharomyces cerevisiae and Schizosaccharomyces pombe. As of today, the resource contains over 24 000 samples. In conjunction with other tools developed by our group (the ChIP-Seq and SSA servers), it allows users to carry out a great variety of analysis task with MGA samples, such as making aggregation plots and heat maps for selected genomic regions, finding peak regions, generating custom tracks for visualizing genomic features in a UCSC genome browser window, or downloading chromatin data in a table format suitable for local processing with more advanced statistical analysis software such as R.

Abstract
Regulation of mRNA stability by RNA-protein interactions contributes significantly to quantitative aspects of gene expression. We have identified potential mRNA targets of the AU-rich element binding protein AUF1. Myc-tagged AUF1 p42 was induced in mouse NIH/3T3 cells and RNA-protein complexes isolated using anti-myc tag antibody beads. Bound mRNAs were analyzed with Affymetrix microarrays. We have identified 508 potential target mRNAs that were at least 3-fold enriched compared to control cells without myc-AUF1. 22.3% of the enriched mRNAs had an AU-rich cluster in the ARED Organism database, against 16.3% of non-enriched control mRNAs. The enrichment towards AU-rich elements was also visible by AREScore with an average value of 5.2 in the enriched mRNAs versus 4.2 in the control group. Yet, numerous mRNAs were enriched without a high ARE score. The enrichment of tetrameric and pentameric sequences suggests a broad AUF1 p42-binding spectrum at short U-rich sequences flanked by A or G. Still, some enriched mRNAs were highly unstable, as those of TNFSF11 (known as RANKL), KLF10, HES1, CCNT2, SMAD6, and BCL6. We have mapped some of the instability determinants. HES1 mRNA appeared to have a coding region determinant. Detailed analysis of the RANKL and BCL6 3’UTR revealed for both that full instability required two elements, which are conserved in evolution. In RANKL mRNA both elements are AU-rich and separated by 30 bases, while in BCL6 mRNA one is AU-rich and 60 bases from a non AU-rich element that potentially forms a stem-loop structure.

Abstract
The influence of thyroid autoimmunity in assisted reproductive technology (ART) outcome in euthyroid women is still controversial. In this study, we retrospectively evaluated embryo quality in 123 euthyroid women undergoing ART with or without thyroid autoantibodies (TAA). Embryo quality was assessed in 119 embryos of 29 infertile patients with TAA and in 394 embryos of 94 infertile patients without TAA. Our results showed not statistically significant differences in age, body mass index, anti-Müllerian hormone, follicle stimulating hormone, free triiodothyronine, and free thyroxine levels between cases and controls. Thyroid stimulating hormone was within the normal range, but significantly higher in TAA patients compared with the controls (2.4 ± 0.8 vs. 2 ± 0.9 mIU/L, respectively, p < .01). The number of oocytes picked up and fertilized was comparable between the two groups. Embryo quality was significantly impaired in women with at least one autoantibody (p < .001). Implantation rate, pregnancy rate, and ongoing pregnancy rate were comparable in the two groups. These results suggest a negative impact of thyroid autoimmunity in embryo quality in women undergoing ART even when thyroid function is normal.

Abstract
Abstract
Many siRNAs and shRNAs induce a form of cell death in all cancer cells that involves silencing a set of critical survival genes, a process called death induced by survival gene elimination (DISE). Mechanistically a 6mer seed sequence (position 2-7 of the guide strand) is sufficient to confer DISE-inducing activity. We have now performed a strand specific screen testing the toxicity of all 4096 possible 6mer seed sequences in a neutral double stranded siRNA backbone. We found an asymmetric preference for guanine in positions 1-3 of the 6mer seed in the most toxic siRNAs which target survival genes that are GC rich in their 3'UTR. During over 800 million years of evolution miRNAs have evolved to avoid guanine in their seed sequences. However, two tumor suppressive miRNAs were found to be killing cancer cells through DISE using G rich toxic seeds in cells exposed to genotoxic stress: 1) the p53 inducible miR-34 family and most of its cell death inducing activity comes from its 6mer seed; and 2) miR-320a, a noncanonical miRNA that is still expressed in cancer cells when miRNA processing genes are mutated. Ago bound upregulated miR-320a is converted from a poorly to a highly toxic miRNA by removal of two adenine nucleotides from its 5' end. Our data suggest that most miRNAs have evolved to avoid induction of DISE but certain tumor suppressive miRNAs utilize this mechanism to kill cancer cells.

Abstract
A total of 1095 patients with operable breast cancer and en-rolled in a randomized clinical trial were analysed for estrogen (ER) and progesterone (PgR) receptor content of their primary tumor, and the relationships between steroid receptor status and several epidemiologic characteristics were studied. The proportion of ER+ and median ER levels increased with age: compared to women younger than 40, those aged 66 or more were approximately three times more likely to have an ER+ tumor (OR = 3.0, 95% C.I. = 1.6–5.7). This difference tended to be more marked after comparison between patients with ER > 100 fmol/mg protein and ER- within the same age groups: OR = 7.04, 95 % C.I. = 2.89–17.12. No association emerged between age and PgR. ER status and concentrations were independent of menopausal status after adjustment for age, whereas the proportion of PgR+ and PgR levels were significantly lower in postmenopausal patients of the same age. The distribution of ER and PgR profiles was similar in relation to family history of breast cancer, reproductive events and other selected epidemiologic characteristics of the patients.

Abstract
SNP2TFBS is a computational resource intended to support researchers investigating the molecular mechanisms underlying regulatory variation in the human genome. The database essentially consists of a collection of text files providing specific annotations for human single nucleotide polymorphisms (SNPs), namely whether they are predicted to abolish, create or change the affinity of one or several transcription factor (TF) binding sites. A SNP's effect on TF binding is estimated based on a position weight matrix (PWM) model for the binding specificity of the corresponding factor. These data files are regenerated at regular intervals by an automatic procedure that takes as input a reference genome, a comprehensive SNP catalogue and a collection of PWMs. SNP2TFBS is also accessible over a web interface, enabling users to view the information provided for an individual SNP, to extract SNPs based on various search criteria, to annotate uploaded sets of SNPs or to display statistics about the frequencies of binding sites affected by selected SNPs.

Thanks to the abundant release of new high-throughput transcript mapping data (CAGE, TSS-seq, GRO-cap) the database could be extended to plant and fungal species. We further report on the expansion of the mass genome annotation (MGA) repository containing promoter-relevant chromatin profiling data and on improvements for the EPD entry viewers. Finally, we present a new data access tool, ChIP-Extract, which enables computational biologists to extract diverse types of promoter-associated data in numerical table formats that are readily imported into statistical analysis platforms such as R.

Abstract
BACKGROUND ChIP-seq and related high-throughput chromatin profilig assays generate ever increasing volumes of highly valuable biological data. To make sense out of it, biologists need versatile, efficient and user-friendly tools for access, visualization and itegrative analysis of such data. RESULTS Here we present the ChIP-Seq command line tools and web server, implementing basic algorithms for ChIP-seq data analysis starting with a read alignment file. The tools are optimized for memory-efficiency and speed thus allowing for processing of large data volumes on inexpensive hardware. The web interface provides access to a large database of public data. The ChIP-Seq tools have a modular and interoperable design in that the output from one application can serve as input to another one. Complex and innovative tasks can thus be achieved by running several tools in a cascade. CONCLUSIONS The various ChIP-Seq command line tools and web services either complement or compare favorably to related bioinformatics resources in terms of computational efficiency, ease of access to public data and interoperability with other web-based tools. The ChIP-Seq server is accessible at http://ccg.vital-it.ch/chipseq/ .

Abstract
PURPOSE Spironolactone (SP) is an effective treatment for polycystic ovary syndrome (PCOS), but it is often associated with menstrual abnormalities whose mechanism is still under investigation. In this study, we investigated the serum sex steroids and endometrial thickness in 30 PCOS patients, before and after one-month 100 mg SP treatment. METHODS Serum FSH, LH, estradiol, progesterone and endometrial thickness were evaluated at the 14th and 16th day of the menstrual cycle, before and during short-term SP treatment. According to the presence (15 cases) or absence (15 cases) of menstrual bleeding at the 14th day during SP, the patients were divided into two groups, which were then compared using a two-tailed Student's t test. RESULTS Serum estradiol and endometrial thickness were lower than pretreatment at both determinations in all patients, but patients with bleeding had significantly lower estradiol values than non-bleeding ones, both before and after therapy. Endometrial thickness was significantly lower in the bleeding group compared with non-bleeding group only at the 16th day of the cycle. These differences were significant, even though the values of estradiol and endometrial thickness remained in the normal range. CONCLUSIONS SP therapy can reduce the values of estradiol and the endometrial thickness in patients with PCOS compared with pretreatment, but PCOS patients with bleeding had pretreatment estradiol values lower than the patients who did not complain of this side effect. Intermenstrual abnormalities may represent the low estrogen impregnation of endometrium due to SP, whose mechanism is complex, involving several factors, such as the effects of some metabolites of SP on estradiol and progesterone production, on their receptors, and the individual metabolism of SP in vivo.

Abstract
BACKGROUND Colorectal cancer is the third most common and the third most lethal cancer in both men and women in developed countries. About 75% of cases are first diagnosed when the disease is classified as localized or regional, undergo potentially curative treatment and enter a post-treatment surveillance program. Although such programs drain significant resources from health systems, empirical evidence of their efficacy is scanty. PATIENTS AND METHODS Dukes B2-C colorectal cancer patients who had no evidence of disease at the end of their front-line treatment (surgery and adjuvant radiochemotherapy, if indicated) were eligible for the trial and randomized to two different surveillance programs. These programs differed greatly in the frequency of diagnostic imaging. They had similar schedules of physical examinations and carcinoembryonic antigen (CEA) assessments. Patients received baseline and yearly health-related quality-of-life (HR-QoL) questionnaires. Primary outcomes were overall survival (OS) and QoL. RESULTS From 1998 to 2006, 1228 assessable patients were randomized, 933 with colon cancer and 295 with rectal cancer. More than 90% of patients had the expected number of diagnostic procedures. Median follow-up duration was 62 months [interquartile range (IQR) 51-86] in the minimal surveillance group and 62 months (IQR 50-85) in the intensive group. At primary analysis, 250 patients had recurred and 218 had died. Intensive surveillance anticipated recurrence, as shown by a significant difference in mean disease-free survival of 5.9 months. Comparison of OS curves of the whole intention-to-treat population showed no statistically significant differences. HR-QoL of life scores did not differ between regimens. CONCLUSION Our findings support the conclusions of other randomized clinical trials, which show that early diagnosis of cancer recurrence is not associated with OS benefit. CLINICALTRIALSGOV NCT02409472.

Abstract
We present an update of EPDNew (http://epd.vital-it.ch), a recently introduced new part of the Eukaryotic Promoter Database (EPD) which has been described in more detail in a previous NAR Database Issue. EPD is an old database of experimentally characterized eukaryotic POL II promoters, which are conceptually defined as transcription initiation sites or regions. EPDnew is a collection of automatically compiled, organism-specific promoter lists complementing the old corpus of manually compiled promoter entries of EPD. This new part is exclusively derived from next generation sequencing data from high-throughput promoter mapping experiments. We report on the recent growth of EPDnew, its extension to additional model organisms and its improved integration with other bioinformatics resources developed by our group, in particular the Signal Search Analysis and ChIP-Seq web servers.

Abstract
AIM The aim of this paper was to identify maternal/pregnancy characteristics, first trimester ultrasound parameters and biochemical indices which are significant independent predictors of large-for-gestational age (LGA) neonates. METHODS An Observational cross-sectional study was conducted at the Fetal Medicine Unit, Department of Obstetrics and Gynecology of the University of Udine (Italy). Seventy-two singleton pregnancies presenting for screening for chromosomal abnormalities by nuchal translucency and maternal serum biochemistry at 11-14 weeks. Linear regression was applied to develop first trimester prediction models for LGA. RESULTS Maternal height, parity, smoking, assisted conception and pregnancy-associated plasma protein-A were significant independent predictors of LGA. PAPP-A cut-off value expressed in MoM of 1.25 used for the study was chosen to obtain good sensitivity and specificity values. CONCLUSION Prediction for birthweight deviations (LGA) is feasible using data available at the routine 11-14 weeks' examination.

Abstract
PURPOSE Ovarian cancer is the fourth cause of death from cancer in women worldwide and the majority of its diagnoses is made in an advanced stage of the disease. Several sonographic scoring systems have been created for a better preoperative discrimination between benign and malignant pelvic masses. The aim of this study was to evaluate the performances of the Risk of the Malignancy Index 3 (RMI 3) and the Pelvic Masses Score (PMS). MATERIALS AND METHODS This retrospective study was performed in 55 women admitted to the department of Obstetrics and Gynecology of University of Udine for surgical exploration of pelvic masses between 2009 and 2012. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated for both the scores. RESULTS PMS showed a sensitivity of 100%, a specificity of 93.8%, a PPV of 70%, and a NPV of 100%, while RMI 3 yielded a sensitivity of 85%, a specificity of 91%, a PPV of 60%, and a NPV of 97.8%. CONCLUSION The authors found that, in discriminating between benign and malignant pelvic disease, the PMS method was more reliable than RMI3. PMS is a simple scoring system which can be used in clinical practice.

Abstract
PURPOSE OF INVESTIGATION To show management of patients with breast lobular carcinoma in situ (LCIS). MATERIALS AND METHODS This study is the retrospective review of 65 patients, between 1996 and 2012, with isolated LCIS of the breast, evaluated through clinical examination, ultrasound, and mammography at the first examination and follow-up. RESULTS In 53 patients (81.54%), clinical examination was negative. In 14/65 (21.54%) cases, ultrasound was positive and led to biopsy. The clusters of tiny calcifications were the predominant mammographic pattern (45 cases, 69.23%). Forty-six patients (70.77%) underwent surgical biopsy after guided stereotactic placement of metallic marker (hook-wire), 12 (18.46%) by stereotactic vacuum biopsy (SVB), 5 (7.69%) by core needle biopsy (CNB) under ultrasound guidance, two (3.08%) patients CNB with clinically palpable nodules. Fourteen (21.54%) women underwent a quadrantectomy or total mastectomy after the first diagnosis; in this latter group follow-up was negative. Among the 51 patients (78.46%) who did not undergo quadrantectomy or total mastectomy, five relapses occurred, respectively, three LCIS and two infiltrating ductal carcinomas (IDC). Follow-up ranged from 12 to 144 months. CONCLUSION LCIS is a risk factor for invasive carcinoma and should be managed with careful follow-up, but if there is a discrepancy between pathology and imaging, surgical excision is mandatory.

Abstract
PURPOSE To assess the effectiveness of inside-out TVT-ABBREVO in the surgical treatment of female stress urinary incontinence (SUI) with mean two-year follow-up. MATERIALS AND METHODS Fifty-six women underwent surgery for moderate-severe SUI. The technology used was the TVT-ABBREVO inside-out. Each woman at 12 and 24 months underwent postoperative evaluation by means of urodynamics, Q-tip test, CST, transperineal ultrasonography, and administration of "King's Health Questionnaire" (KHQ). RESULTS The mean age of the women was 57.03 +/- 11.1 years (range 42-75). Postoperative urodynamics (12 months follow-up) resulted to be normal in 43/56 patients (76.79%), in 10/56 (17.86%) cases resulted in a considerable improvement of the symptomatology, and only 1/56 (1.78%) case had de novo overactive bladder (OAB), in 2/56 (3.57%) symptomatology unchanged. After administration of the KHQ 43/56 cases (76.79%) had resolution of the symptomatology, 10/56 cases (17.86%) improvement of the symptomatology, and no change in 3/56 cases (5.36%). CONCLUSION In the authors' experience, the TVT-ABBREVO resulted technically simple. The TVT-ABBREVO procedure provides high objective and subjective long-term efficacy, a clinically meaningful improvement in patient quality of life, and an excellent safety profile.
