Ambulatory MiniArc Precise sling under local anesthesia for stress urinary incontinence: Feasibility and outcome

Aims: The aim of the study is to assess the feasibility of ambulatory stress urinary incontinence (SUI) surgery using the MiniArc Precise single-incision urethral sling without increasing the number of complications. Settings and design: This was a retrospective observational study of prospectively collected data carried out in a Tertiary Referral Hospital in Barcelona, Spain. Materials and methods: Forty patients diagnosed with SUI or stress predominant mixed urinary incontinence (MUI) treated surgically between November 2011 and November 2013. The MiniArc Precise® sling was inserted under local anesthesia in the ambulatory setting. Satitistical analysis used: Descriptive statistics included frequencies and percentages for categorical variables and mean and range for quantitative variables. The statistical package used was SPSS version 17.0. Results: Urodynamic studies showed SUI in 78% of cases and stress predominant MUI in 17%. Clinical findings included SUI in 56% of cases and MUI in 44%, with positive stress tests in all participants. The mean intraoperative pain (1-10 Visual Analog Scale) was 2. All patients were satisfied with the use of local anesthesia in the outpatient setting. Perioperative complications did not occur. One case of urinary retention and two cases of urinary tract infection (UTI) developed within this 1st month after operation and were successfully managed conservatively. Midterm complications included eight cases of UTI and four de novo urge incontinence. Conclusions: Placement of the MiniArc Precise sling under local anesthesia is a feasible and safe technique, which when carried out by an experienced surgeon allows to be done as an outpatient basis without increasing the rate of postprocedural complications. Keywords: Ambulatory surgical procedures, local anesthesia, MiniArc Precise, patient satisfaction, stress urinary incontinence, suburethral sling

Second breast-conserving therapy with interstitial brachytherapy (APBI) as a salvage treatment in ipsilateral breast tumor recurrence: a retrospective study of 40 patients

Purpose: breast-conserving treatment (BCT) have emerged as an alternative to mastectomy in patients with ipsilateral breast tumor recurrence (IBTR). We evaluated survival outcomes and treatment-related toxicity in a series of 40 patients with IBTR, who underwent tumorectomy plus interstitial brachytherapy (APBI) as a salvage treatment. Material and methods: retrospective analysis included 40 patients diagnosed with IBTR and treated with intraoperative (26 patients) or post-operative (14 patients) multicatheter brachytherapy for APBI at our institution between June 2002 and October 2017. We assessed cosmesis, toxicity, overall survival (OS), and cancer-specific survival (CSS). Results: tumorectomy was performed in all cases, including intraoperative tumor margin assessment and sentinel node biopsy. Median age was 65 years (range, 41-92). The total prescribed dose was 32 Gy (8 fractions) in 19 patients and 34 Gy (10 fractions) in 20 patients. One elderly patient (age 92) received a single fraction of 16 Gy. Median follow-up was 61.5 months (range, 6-153). A median of 14 tubes were inserted. Mean treated V100 was 115 cc. Two patients developed a second relapse at 3 and 5 years after salvage treatment: one patient underwent salvage mastectomy and remains alive 10 years after brachytherapy, and the second one developed both local relapse and bone metastasis. The disease is stable at present. Five-year OS and CSS rates were 85.3% and 97.5%, respectively. Two patients died from cancer-related causes. Acute and late toxicity rates were low; seven patients developed acute infectious mastitis. Late fibrosis > grade 3 and late mastitis were observed in 14 and 6 cases, respectively. Conclusions: second BCT with APBI as a salvage treatment in ipsilateral breast recurrence achieves good local disease control, with a satisfactory toxicity profile compared to mastectomy. This approach seems to be safe and effective, although more data from randomized trials are needed

Ecto-nucleotidases activities in the contents of ovarian endometriomas: potential biomarkers of endometriosis

Endometriosis, defined as the growth of endometrial tissue outside the uterus, is a common gynecologic condition affecting millions of women worldwide. It is an inflammatory, estrogen-dependent complex disorder, with broad symptomatic variability, pelvic pain, and infertility being the main characteristics. Ovarian endometriomas are frequently developed in women with endometriosis. Late diagnosis is one of the main problems of endometriosis; thus, it is important to identify biomarkers for early diagnosis. The aim of the present work is to evaluate the ecto-nucleotidases activities in the contents of endometriomas. These enzymes, through the regulation of extracellular ATP and adenosine levels, are key enzymes in inflammatory processes, and their expression has been previously characterized in human endometrium. To achieve our objective, the echo-guided aspirated fluids of endometriomas were analyzed by evaluating the ecto-nucleotidases activities and compared with simple cysts. Our results show that enzyme activities are quantifiable in the ovarian cysts aspirates and that endometriomas show significantly higher ecto-nucleotidases activities than simple cysts (5.5-fold increase for ATPase and 20-fold for ADPase), thus being possible candidates for new endometriosis biomarkers. Moreover, we demonstrate the presence of ecto-nucleotidases bearing exosomes in these fluids. These results add up to the knowledge of the physiopathologic mechanisms underlying endometriosis and, open up a promising new field of study

An Overview of the IberSpeech-RTVE 2022 Challenges on Speech Technologies

Evaluation campaigns provide a common framework with which the progress of speech technologies can be effectively measured. The aim of this paper is to present a detailed overview of the IberSpeech-RTVE 2022 Challenges, which were organized as part of the IberSpeech 2022 conference under the ongoing series of Albayzin evaluation campaigns. In the 2022 edition, four challenges were launched: (1) speech-to-text transcription; (2) speaker diarization and identity assignment; (3) text and speech alignment; and (4) search on speech. Different databases that cover different domains (e.g., broadcast news, conference talks, parliament sessions) were released for those challenges. The submitted systems also cover a wide range of speech processing methods, which include hidden Markov model-based approaches, end-to-end neural network-based methods, hybrid approaches, etc. This paper describes the databases, the tasks and the performance metrics used in the four challenges. It also provides the most relevant features of the submitted systems and briefly presents and discusses the obtained results. Despite employing state-of-the-art technology, the relatively poor performance attained in some of the challenges reveals that there is still room for improvement. This encourages us to carry on with the Albayzin evaluation campaigns in the coming years.This work was partially supported by Radio Televisión Española through the RTVE Chair at the University of Zaragoza, and Red Temática en Tecnologías del Habla (RED2022-134270-T), funded by AEI (Ministerio de Ciencia e Innovación); It was also partially funded by the European Union’s Horizon 2020 research and innovation program under Marie Skłodowska-Curie Grant 101007666; in part by MCIN/AEI/10.13039/501100011033 and by the European Union “NextGenerationEU”/ PRTR under Grants PDC2021-120846C41 PID2021-126061OB-C44, and in part by the Government of Aragon (Grant Group T3623R); it was also partially funded by the Spanish Ministry of Science and Innovation (OPEN-SPEECH project, PID2019-106424RB-I00) and by the Basque Government under the general support program to research groups (IT-1704-22), and by projects RTI2018-098091-B-I00 and PID2021-125943OB-I00 (Spanish Ministry of Science and Innovation and ERDF) as well

Active methods in electricity and magnetism courses: Influence of degree, academic level and gender on student performance

[EN] The performance of first-year students in electromagnetism (E&M) courses of different engineering degrees at a Spanish public university was measured using the Brief Electricity and Magnetism Assessment (BEMA), a standard research-based instrument to assess students' understanding after attending introductory courses in electricity and magnetism. In all cases, Flipped classroom (FC) built on information and communications technology was used. The objective of this paper is to analyse if the gain in the BEMA pre and post-test results is influenced by several factors such as the degree, the students' academic grade, and gender. Moreover, as some studies have shown that the students' retention of the concepts was significantly stronger in active learning than in traditional approaches, a third BEMA test was performed by the students to analyse the long-term retention gain dependence on the same factors. Students from different engineering degree programs were asked to complete two BEMA tests during the course and a third one after a few months. ANOVA tests were used to analyse the existence of significant differences in gain between student degree programs, student academic level and student gender. Results have shown no differences in the BEMA performance by degree program, but significant differences were found by academic level and gender. Retention did not depend on the degree course but on the academic level. Mean gain value by academic level, and gender was obtained and concluded that the best students presented the best gain results and that gain depends on the students' gender: males outperformed females in the BEMA tests, although there were no significant differences in the course grades. It is thus necessary to understand these differences and to implement measures in daily teaching work to improve women's performance.Authors would like to thank the Instituto de Ciencias de la Educacion (ICE) in the Universitat Politecnica de Valencia for their help, through the Innovation and Educational Quality Program and for supporting the team of the Innovacion en Metodologias Activas para el Aprendizaje de la Fisica (e-MACAFI) .

Axillary lymph node dissection versus radiotherapy in breast cancer with positive sentinelnodes after neoadjuvant therapy (ADARNAT trial)

Introduction: Breast cancer surgery currently focuses on de-escalating treatment without compromising patient survival. Axillary radiotherapy (ART) now replaces axillary lymph node dissection (ALND) in patients with limited sentinel lymph node (SLN) involvement during the primary surgery, and this has significantly reduced the incidence of lymphedema without worsening the prognosis. However, patients treated with neoadjuvant systemic treatment (NST) cannot benefit from this option despite the low incidence of residual disease in the armpit in most cases. Data regarding the use of radiotherapy instead of ALND in this population are lacking. This study will assess whether ART is non-inferior to ALND in terms of recurrence and overall survival in patients with positive SLN after NST, including whether it reduces surgery-related adverse effects. Methods and analyses: This multicenter, randomized, open-label, phase 3 trial will enroll 1660 patients with breast cancer and positive SLNs following NST in approximately 50 Spanish centers over 3 years. Patients will be stratified by NST regimen and nodal involvement (isolated tumoral cells or micrometastasis versus macrometastasis) and randomly assigned 1:1 to ART without ALND (study arm) or ALND alone (control arm). Level 3 and supraclavicular radiotherapy will be added in both arms. The primary outcome is the 5-year axillary recurrence determined by clinical and radiological examination. The secondary outcomes include lymphedema or arm dysfunction, quality of life based (EORTC QLQ-C30 and QLQ-BR23 questionnaires), disease-free survival, and overall survival. Discussion: This study aims to provide data to confirm the efficacy and safety of ART over ALND in patients with a positive SLN after NST, together with the impact on morbidity. Ethics and dissemination: The Research Ethics Committee of Bellvitge University Hospital approved this trial (Protocol Record PR148/21, version 3, 1/2/2022) and all patients must provide written informed consent. The involvement of around 50 centers across Spain will facilitate the dissemination of our results

Chromatin regulation by Histone H4 acetylation at Lysine 16 during cell death and differentiation in the myeloid compartment

Histone H4 acetylation at Lysine 16 (H4K16ac) is a key epigenetic mark involved in gene regulation, DNA repair and chromatin remodeling, and though it is known to be essential for embryonic development, its role during adult life is still poorly understood. Here we show that this lysine is massively hyperacetylated in peripheral neutrophils. Genome-wide mapping of H4K16ac in terminally differentiated blood cells, along with functional experiments, supported a role for this histone post-translational modification in the regulation of cell differentiation and apoptosis in the hematopoietic system. Furthermore, in neutrophils, H4K16ac was enriched at specific DNA repeats. These DNA regions presented an accessible chromatin conformation and were associated with the cleavage sites that generate the 50 kb DNA fragments during the first stages of programmed cell death. Our results thus suggest that H4K16ac plays a dual role in myeloid cells as it not only regulates differentiation and apoptosis, but it also exhibits a non-canonical structural role in poising chromatin for cleavage at an early stage of neutrophil cell death

Long‐term predictors of residual or recurrent cervical intraepithelial neoplasia 2‐3 after treatment with a large loop excision of the transformation zone: a retrospective study

Objective: To assess the long-term risk factors predicting residual/recurrent cervical intraepithelial neoplasia (CIN 2–3) and time to recurrence after large loop excision of the transformation zone (LLETZ). Design: Retrospective study. Setting: Colposcopy clinic. Population: 242 women with CIN 2–3 treated between 1996 and 2006 and followed up until June 2016. Methods: Age, margins and high risk-human papillomavirus (HR-HPV) were estimated using Cox proportional hazard and unconditional logistic regression models. The cumulative probability of treatment failure was estimated by Kaplan-Meier analysis. Main Outcome measure: Histologically confirmed CIN 2-3, HR-HPV, margins, age. Results: CIN 2-3 was associated with HR-HPV (HR =30.5; 95% CI =3.80-246.20); age >35 years (HR =5.53; 95% CI =1.22-25.13); and margins (HR = 7.31; 95% CI = 1.60–33.44). HR-HPV showed a sensitivity of 88.8% and a specificity of 80%. Ecto(+)/endocervical(+)(16.7%), uncertain (19.4%) and ecto(-)/endocervical(+) margins (9.1%) showed a higher risk of recurrence (OR = 13.20(95% CI =1.02-170.96), 15.84(95% CI =3.02-83.01), and 6.60(95% CI =0.88-49.53)), respectively. Women with involved margins and/or HR-HPV positive had more treatment failure than those who were HR-HPV negative or had clear margins (P-log rank<0.001). Conclusions: HR-HPV and margins seem essential for stratifying post- LLETZ risk, and enable personalised management. Given that clear margins present a lower risk, a large excision may be indicated in older women in order to reduce the risk. Funding statement: This study has received no funding
