Abstract
Coupons of a medical grade PLDL polymer matrix uniaxially reinforced with a 15% volume fraction of Mg wires have been manufactured by fused filament fabrication for the first time. Two different types of Mg wires, without and with a surface treatment by plasma electrolytic oxidation were used. Both composite materials were subjected to degradation in phosphate buffer solution over a 3-week period, and their degradation and deformation micromechanisms were analysed in detail. Additionally, the materials were subjected to extensive mechanical testing under various loading conditions, and the interface strength was also analysed. It was found that the presence of the Mg wires improves the mechanical behaviour and accelerates the corrosion rate of the composite with respect that of the polymer matrix and these properties can be further tailored through the surface-modification of Mg wires by plasma electrolytic oxidation. The additive manufacturing strategy presented opens the path to fabricate multimaterial implants and scaffolds with complex shape and tailored properties provided by biodegradable polymers reinforced with either Mg and Zn particles and/or wires.

Abstract
INTRODUCTION We present the Spanish Society of Neurorehabilitation's guidelines for adult acquired brain injury (ABI) rehabilitation. These recommendations are based on a review of international clinical practice guidelines published between 2013 and 2020. DEVELOPMENT We establish recommendations based on the levels of evidence of the studies reviewed and expert consensus on population characteristics and the specific aspects of the intervention or procedure under research. CONCLUSIONS All patients with ABI should receive neurorehabilitation therapy once they present a minimal level of clinical stability. Neurorehabilitation should offer as much treatment as possible in terms of frequency, duration, and intensity (at least 45-60minutes of each specific form of therapy that is needed). Neurorehabilitation requires a coordinated, multidisciplinary team with the knowledge, experience, and skills needed to work in collaboration both with patients and with their families. Inpatient rehabilitation interventions are recommended for patients with more severe deficits and those in the acute phase, with outpatient treatment to be offered as soon as the patient's clinical situation allows it, as long as intensity criteria can be maintained. The duration of treatment should be based on treatment response and the possibilities for further improvement, according to the best available evidence. At discharge, patients should be offered health promotion, physical activity, support, and follow-up services to ensure that the benefits achieved are maintained, to detect possible complications, and to assess possible changes in functional status that may lead the patient to need other treatment programmes.

Abstract
The mechanical, thermal, and biological performance of fabrics manufactured with hybrid PLA/PCL commingled yarns were studied. Commingled hybrid yarns take advantage of the higher elastic modulus of PLA and the higher ductility and toughness of PCL to produce yarns and fabrics with high strength and ductility that is transferred to the woven textiles. Furthermore, PLA and PCL exhibit different degradation rates and also allow to tailor this property. Degradation of the textiles was carried out in phosphate-buffered saline solution for up to 160 days at 37 °C and 50 °C (accelerated degradation). Neither the thermal nor the mechanical properties were altered by immersion at 37 °C during 80 days and a slight degradation was observed as a result of chain scission of the PLA fibres after 160 days. However, immersion at 50 °C led to a rapid reduction in strength after 40 days due to the hydrolysis of PLA, and the fabric was highly degraded after 160 days as a result of chain scission in PCL. Finally, while indirect tests did not predict optimal biocompatibility, the direct tests provided a different perspective of the cell interaction between the textile and pre-osteoblasts regarding cell attachment and cell morphology. These results show the potential of hybrid commingled yarns to manufacture textile scaffolds of biodegradable polymers with tailored mechanical properties and good ductility for connective tissue engineering (ligaments and tendons).

Abstract
The gut microbiome can metabolise food components, such as dietary fibres and various phytochemicals; and the microbiome can also synthesise some nutrients, for example B vitamins. The metabolites produced by bacteria and other micro-organisms in the colon can have implications for health and disease risk. Some of these metabolites are epigenetically active, and can contribute to changes in the chemical modification and structure of chromatin by affecting the activity and expression of epigenetically-active enzymes, for example histone deacetylases and DNA methyltransferases. The epigenetic activity of such gut microbiome metabolites is reviewed herein.

Abstract
BACKGROUND The Coronavirus pandemic outbreak in 2019 and the saturation of healthcare system led to an increased use of digital tools for surveillance. In this study we described our experience using telemedicine to follow-up on patients with intraductal papillary mucinous neoplasms during the COVID-19 era and analyze those factors associated to patients' satisfaction. METHODS This 1-year retrospective observational study enrolled patients with intraductal papillary mucinous neoplasms followed-up by telemedicine during COVID-19 outbreak. Patients with high-risk features needing on-site physical examination or declining remote follow-up were excluded. A 13-question survey was conducted; demographic, geographic, and employment information was collected. Univariate and multivariate analyses were performed to evaluate those factors associated to patients' satisfaction. RESULTS Out of 287, a total of 177 patients with intraductal papillary mucinous neoplasms were included: the mean age was 69 (44-87) years and the male/female ratio was 0.78. A total of 80 (45.2%) patients had previously experienced abdominal pain. Most patients (85.3%) were satisfied with telemedicine: at univariate analysis, age ≥70 years (P = .007), retirement (P = .001), and absence of previous abdominal pain (P = .05) were significantly associated with patient satisfaction. At multivariate analysis, the absence of previous abdominal pain was the only factor independently associated with patient satisfaction (odds ratio 5.964, 95% confidence interval 2.21-16.11, P < .001). CONCLUSION Telemedicine allows a new follow-up strategy that can be used in selected patients with intraductal papillary mucinous neoplasms. The absence of previous abdominal pain is associated with patient satisfaction during follow-up. Further studies are needed to evaluate safety of remote follow-up in patients with intraductal papillary mucinous neoplasms.

Abstract
Study question Do the different types of vaccines against SARS-CoV-2 influence the results of an Assisted Reproduction treatment? Summary answer The type of vaccine administered against SARS-CoV-2 does not affect the results in women performing an Assisted Reproduction treatment. What is known already Since the COVID-19 pandemic was declared, the search for vaccines has become the priority, so its development has represented a step towards herd immunity in a short period of time. Despite this encouraging advance, vaccine hesitancy in reproductive-aged women has been heightened because of the spread of misinformation stating that COVID-19 vaccines will cause sterility. Due to the lack of information and the clinical relevance, the objective of this work was to evaluate the impact of the different types of vaccines on women’s fertility. Study design, size, duration Retrospective and observational study during January-October 2021 in women vaccinated against SARS-CoV-2 and performing an Assisted Reproductive treatment in any of the 11 clinics belonging to the IVIRMA group in Spain. The Control group included patients performing a treatment during the same study period but who had not yet been vaccinated. The study was approved by an Institutional Review Board (2109-MADR-084-AR) Participants/materials, setting, methods All women, those who had received the complete vaccination schedule, regardless of the type of vaccine administered mRNA or viral vector, and women from the control group underwent the same ovarian stimulation protocol. The Assisted Reproduction treatment was performed with their own oocytes in all cases. Statistical analyses were performed using the Statistical Package for Social Sciences 19.0 (IBM Corporation, Armonk, NY, USA). Main results and the role of chance We included 510 patients distributed as follows: 13.5% (n = 69) received a viral vector vaccine either the adenovirus serotype 26 vector vaccine (Ad26.CoV2.S; Johnson & Johnson; n = 31) or the chimpanzee adenovirus vector vaccine (ChAdOx; AstraZeneca; n = 38). The remaining 86.5% (n = 441) received an mRNA vaccine from either Pfizer-BioNTech (n = 336) or Moderna (n = 105). Sample size for control group was n = 1190 Our results showed that women vaccinated with Johnson & Johnson have a higher average age (39.7 ± 4.3) than the other groups, although no statistical difference was observed (p = 0.072); that is, AstraZeneca (36.8 ± 1.7), Moderna (35.7 ± 1.5), Pfizer (34.6 ± 1.6) and the control group (37.8 ± 2.7). This circumstance did not affect other parameters such as the days of stimulation (p = 0.336) or the doses of FSH administered (p = 0.392), where no statistical differences were recorded between the vaccinated and the control group. Finally, the number of oocytes were as follows, Johnson & Johnson (9.2 ± 2.6), AstraZeneca (7.7 ± 1.2), Moderna (11.3 ± 1.8), Pfizer (12.6 ± 1.0), and the control group (10.2 ± 1.5), p = 0.06. Limitations, reasons for caution This is an observational study, and thus possible confounders cannot be excluded entirely. More data are needed to draw firm conclusions, and it will be critical to increase the sample size to check if the results observed in this work remains in the general population Wider implications of the findings This is the first study to assess whether the type of vaccine administered against SARS-CoV-2, mRNA, or viral vector, affects ovarian function in ART. These early findings suggest no measurable detrimental on ovarian response regardless of vaccine received. Trial registration number not applicable

Abstract
Yeast selection for the wine industry in Spain started in 1950 for the understanding of the microbial ecology, and for the selection of optimal strains to improve the performance of alcoholic fermentation and the overall wine quality. This process has been strongly developed over the last 30 years, firstly on Saccharomyces cerevisiae, and, lately, with intense activity on non-Saccharomyces. Several thousand yeast strains have been isolated, identified and tested to select those with better performance and/or specific technological properties. The present review proposes a global survey of this massive ex-situ preservation of eukaryotic microorganisms, a reservoir of biotechnological solutions for the wine sector, overviewing relevant screenings that led to the selection of strains from 12 genera and 22 species of oenological significance. In the first part, the attention goes to the selection programmes related to relevant wine-producing areas (i.e. Douro, Extremadura, Galicia, La Mancha and Uclés, Ribera del Duero, Rioja, Sherry area, and Valencia). In the second part, the focus shifted on specific non-Saccharomyces genera/species selected from different Spanish and Portuguese regions, exploited to enhance particular attributes of the wines. A fil rouge of the dissertation is the design of tailored biotechnological solutions for wines typical of given geographic areas.

Abstract
The feasibility to manufacture scaffolds of poly-lactic acid reinforced with Zn particles by fused filament fabrication is demonstrated for the first time. Filaments of 2.85 mm in diameter of PLA reinforced with different weight fractions of μm-sized Zn - 1 wt.% Mg alloy particles (in the range 3.5 to 17.5 wt.%) were manufactured by a double extrusion method in which standard extrusion is followed by precision extrusion in a filament-maker machine. Filaments with constant diameter, negligible porosity and a homogeneous reinforcement distribution were obtained for Zn weight fractions of up to 10.5%. It was found that the presence of Zn particles led to limited changes in the physico-chemical properties of the PLA that did not affect the window temperature for 3D printing nor the melt flow index. Thus, porous scaffolds could be manufactured by fused filament fabrication at 190 °C with poly-lactic acid/Zn composites containing 3.5 and 7 wt.% of Zn and at 170 °C when the Zn content was 10.5 wt.% with excellent dimensional accuracy and mechanical properties.

Abstract
BACKGROUND AND AIMS Emergency General Surgery (EGS) conditions account for millions of deaths worldwide, yet it is practiced without benchmarking-based quality improvement programs. The aim of this observational, prospective, multicenter, nationwide study was to determine the best benchmark cutoff points in EGS, as a reference to guide improvement measures. METHODS Over a 6-month period, 38 centers (5% of all public hospitals) attending EGS patients on a 24-h, 7-days a week basis, enrolled consecutive patients requiring an emergent/urgent surgical procedure. Patients were stratified into cohorts of low (i.e., expected morbidity risk <33%), middle and high risk using the novel m-LUCENTUM calculator. RESULTS A total of 7258 patients were included; age (mean ± SD) was 51.1 ± 21.5 years, 43.2% were female. Benchmark cutoffs in the low-risk cohort (5639 patients, 77.7% of total) were: use of laparoscopy ≥40.9%, length of hospital stays ≤3 days, any complication within 30 days ≤ 17.7%, and 30-day mortality ≤1.1%. The variables with the greatest impact were septicemia on length of hospital stay (21 days; adjusted beta coefficient 16.8; 95% CI: 15.3 to 18.3; P < .001), and respiratory failure on mortality (risk-adjusted population attributable fraction 44.6%, 95% CI 29.6 to 59.6, P < .001). Use of laparoscopy (odds ratio 0.764, 95% CI 0.678 to 0.861; P < .001), and intraoperative blood loss (101-500 mL: odds ratio 2.699, 95% CI 2.152 to 3.380; P < .001; and 500-1000 mL: odds ratio 2.875, 95% CI 1.403 to 5.858; P = .013) were associated with increased morbidity. CONCLUSIONS This study offers, for the first time, clinically-based benchmark values in EGS and identifies measures for improvement.

Abstract
Background: The purpose of this study is to develop and validate a low-cost simulation model and training program for the acquisition of basic skills in endoscopic sinus surgery. Methodology: Experimental study. An eight-task low-cost simulation model was developed based on feeding bottles. Junior residents, general otolaryngologists, and fellowship-trained rhinologists (experts) were recorded performing each task. Operative time and number of errors were measured. Videos were evaluated by two blinded experts using a validated global rating scale (GRS) and a specific rating scale (SRS). A group of residents completed a six-session training program and then were recorded and evaluated using the same methodology. Results: Twenty-five participants were recruited. Statistically significant higher scores in the GRS and SRS and lower operative time and errors at higher levels of expertise were found. A significant correlation between SRS and GRS was found. Seven residents completed the training program. A significant improvement of SRS and GRS scores and reduction of operative time and errors were observed after training. Moreover, compared to experts, statistically significant fewer errors were made by residents after training, and no significant differences were found in terms of performance quality and operative time among these groups. Conclusions: Our low-cost simulation model can be accurately used as a validated objective assessment and training tool for basic endoscopic skills necessary for FESS, and can be potentially used in any otolaryngology surgical training program for residents.

Abstract
Struvite from nutrient-rich wastewaters has been identified as a potential substitute for commercial mineral fertilisers, with the added benefit of reducing threats to global food security by prolonging phosphate rock reserves. A fertilisation test using grass (Brachiaria brizantha Marandú) and a sand column leaching test was conducted to determine the agronomic effectiveness of struvite precipitates produced from the supernatant of dewatered sewage sludge (centrate) from a municipal Wastewater Treatment Plant (WWTP). The performance of this struvite as a fertiliser was compared with biosolids and commercial fertilisers (Urea and Triple15). The results show that the concentration of heavy metals in struvite was lower than in biosolids and below the limits of Colombia and European fertiliser regulations. Struvite increased the uptake of N and P in grass, resulting in crop yields similar to other treatments tested. Struvite use as an effective slow-release fertiliser is highly dependent on the size of crystal particles, particularly in achieving low P losses, but resulted in high N loss in the sand columns tested; N loses from struvite were higher than in the commercial fertilisers due to the struvite small particle size. Therefore, struvite represents a suitable opportunity to recover and recycle nutrients from municipal sewage sludge, facilitating the effective reuse of P and N in agriculture and uptake by plants.

Abstract
Ecuador is a signatory of the Stockholm Convention on chemical substances and hazardous waste and is responsible for complying with the guidelines for the environmentally adequate disposal of Polychlorinated Biphenyls (PCBs) in the country until 2025. The global management of PCBs begins with the sampling of transformers, analysis of dielectric oil, characterization and final disposal of transformers, oil and PCB material belonging to the electricity sector and private owners. The information on the characterization of PCBs is recorded and stored in a computer system called the National PCB Inventory and Monitoring System (SNIS-PCB), in which, the information of 216,632 transformers must be recorded for the present investigation. In the past 2018, the system registered 90,346 transformers, equivalent to 40% of the inventory, 3,494 of them were contaminated and are owned by electricity companies, and it was estimated that there are 1,063 contaminated transformers from private owners. The objective of the research is to analyze the economic and technical feasibility of the technologies available and allowed in the national regulations for the final disposal of these hazardous wastes. According to the technical characteristics of the technologies, logistical limitations and quantity of PCBs in the country, it has been determined that Dichlorination is a technological option that can be used for the treatment of PCBs, also offering the opportunity of decontamination, reuse of the material, and it is friendly with the environment.

Abstract
Single-exon coding sequences (CDSs), also known as ‘single-exon genes’ (SEGs), are defined as nuclear, protein-coding genes that lack introns in their CDSs. They have been studied not only to determine their origin and evolution but also because their expression has been linked to several types of human cancers and neurological/developmental disorders, and many exhibit tissue-specific transcription. We developed SinEx DB that houses DNA and protein sequence information of SEGs from 10 mammalian genomes including human. SinEx DB includes their functional predictions (KOG (euKaryotic Orthologous Groups)) and the relative distribution of these functions within species. Here, we report SinEx 2.0, a major update of SinEx DB that includes information of the occurrence, distribution and functional prediction of SEGs from 60 completely sequenced eukaryotic genomes, representing animals, fungi, protists and plants. The information is stored in a relational database built with MySQL Server 5.7, and the complete dataset of SEG sequences and their GO (Gene Ontology) functional assignations are available for downloading. SinEx DB 2.0 was built with a novel pipeline that helps disambiguate single-exon isoforms from SEGs. SinEx DB 2.0 is the largest available database for SEGs and provides a rich source of information for advancing our understanding of the evolution, function of SEGs and their associations with disorders including cancers and neurological and developmental diseases.

Abstract
IntroductionThe hormonal imbalance produced by antipsychotics can be detected by symptoms, such as: infertility, acne, hirsutism, sexual dysfunction and galactorrhea. We consider especially important the study of women's diseases, which may develop due to hyperprolactinemia, specifically: breast cancer, endometrial cancer and osteoporosis.ObjectiveTo undertake a systematic review about the relationship between hyperprolactinemia as a result of the treatment with antipsychoticsand endometrial and breast cancer.MethodAn exhaustive search was performed on PUBMED and COCHRANE (from 2006 to 2015).Fifteen papers were selected including comparative studies, clinical trials and clinical reviews.ResultsWith respect to endometrial carcinoma, there is no direct relationship with the use of antipsychotics. However, most papers have suggested that the blood prolactin elevation is a risk factor in the development of endometrial engrossment, which could lead to endometrial hyperplasia, polyps and endometrial cancer. Related to the use of antipsychotics as a treatment for schizophrenic women and breast carcinoma, a significant association was found and this association is strengthened through the interaction of other factors like the fact that women with schizophrenia are less worried about going to the clinical screening reviews in their health centre, smoking, and lower physical activity than healthy women.ConclusionsAripiprazolis associated with a low prevalence of hyperprolactinemia. Menopausal women, the obese, and women who smoke receiving antipsychotics that produce hyperprolactinemia have the greatest risk of developing endometrial pathology. Schizophrenic women with hyperprolactinemia due to antipsychotics and loss of motivation to go to screening activities have a greater risk of breast cancer. Sexual dysfunction could be a non-adherence treatment factor.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
INTRODUCTION The diagnosis of growth hormone deficiency (GHD) is difficult to determine, and could be associated with severe complications, especially in the neonatal period. The stimulation test of growth hormone (GH) secretion is considered the gold standard for diagnosis, but it has methodological complications and is associated with adverse effects. Neonates present physiological increased secretion of GH, representing a diagnostic window. OBJECTIVE To evaluate if the dried blood spot on filter paper obtained in the neonatal period, as part of a neonatal screening for con genital hypothyroidism and phenylketonuria, allows differentiating patients with GHD from those who do not have it. PATIENTS AND METHOD Study of cases and controls by measuring the GH concen tration in dried blood spot on filter paper obtained in the neonatal period, comparing controls with GHD with cases with discarded deficiency. The sample was extracted from the filter paper, obtaining two 0.125 inch discs per each patient from the center of the blood spot on the paper, for a highly sen sitive ELISA assay for human GH based on the use of polyclonal antibodies against 22 kDa recom binant human GH. RESULTS Seven cases of GHD and ten controls were obtained. The median GH concentration of the dried blood spot in the cases is 2.0 ng/ml (Interquartile range 3.6 ng/ml) and 2.05 ng/ml (Interquartile range 2.0 ng/ml) in the controls, Mann-Whitney U test 30.5 (p = 0.68). The two cases with multiple pituitary-hormone deficiency (MPHD) present concentrations lower than 1 ng/ml. CONCLUSION The dried blood spot sample did not differentiate GHD patients from control cases, although MPHD cases present much lower concentrations compared to isolated growth hor mone deficiency (IGHD).

Abstract
Photon statistics is a powerful tool for characterizing the emission dynamics of nanoscopic systems and their photophysics. Recent advances that combine correlation spectroscopy with scanning tunneling microscopy induced luminescence (STML) have allowed the measurement of the emission dynamics from individual molecules and defects, demonstrating their nature as single-photon emitters. The application of correlation spectroscopy to the analysis of the dynamics of a well-characterized adsorbate system in an ultrahigh vacuum remained to be demonstrated. Here, we combine single-photon time correlations with STML to measure the dynamics of individual H2 molecules between a gold tip and an Au(111) surface. An adsorbed H2 molecule performs recurrent excursions below the tip apex. We use the fact that the presence of the H2 molecule in the junction modifies plasmon emission to study the adsorbate dynamics. Using the H2 molecule as a chopper for STM-induced optical emission intensity, we demonstrate bunching in the plasmonic photon train in a single measurement over 6 orders of magnitude in the time domain (from microseconds to seconds) that takes only a few seconds. Our findings illustrate the power of using photon statistics to measure the diffusion dynamics of adsorbates with STML.

Abstract
Ultra-High Pressure Homogenization Sterilization (UHPHS) allows the sterilization of fluid foods at low temperatures or even in refrigeration. UHPHS is a continuous technique that allows to process 10,000 L/h with a single pump working at 300 MPa with an imbalance of 1 MPa (Ypsicon EP2409583). During the process, fluid temperature increases less than 5 ∘C. The technique is sensory gentle not affecting molecules formed by covalent bonds so aroma and pigments are unaltered. During the process of white musts, the complete elimination of yeasts, bacteria and spores can be achieved and the must may remain unfermented for several months-years if stored in amicrobic conditions. The technique is also effective in the destruction of polyphenol oxidase (PPO) enzymes. Final size particle is 100–300 nm allowing to increase the availability of yeast assimilable nitrogen and opens the opportunity to nano-encapsulate flavours. Destruction of PPOs and elimination of microorganisms help to reduce sulphites in wines. UHPHS facilitates the use of new biotechnologies such as the use of non-Saccharomyces yeasts and yeast-bacteria co-inoculations by enabling a better implantation of the starters in absence of competition with wild grape microorganisms.

Abstract
PURPOSE To retrospectively assess outcomes and to identify prognostic factors in patients diagnosed with intermediate-risk (IR) prostate cancer (PCa) treated with primary external beam radiotherapy (EBRT). MATERIALS AND METHODS Data were obtained from the multi-institutional Spanish RECAP database, a population-based prostate cancer registry in Spain. All IR patients (NCCN criteria) who underwent primary EBRT were included. The following variables were assessed: age; prostate-specific antigen (PSA); Gleason score; clinical T stage; percentage of positive biopsy cores (PPBC); androgen deprivation therapy (ADT); and radiotherapy dose. The patients were stratified into one of three risk subcategories: (1) favourable IR (FIR; GS 6, ≤ T2b or GS 3 + 4, ≤ T1c), (2) marginal IR (MIR; GS 3 + 4, T2a-b), and (3) unfavourable IR (UIR; GS 4 + 3 or T2c). Biochemical relapse-free survival (BRFS), disease-free survival (DFS), cancer-specific survival (CSS), and overall survival (OS) were assessed. RESULTS A total of 1754 patients from the RECAP database were included and stratified by risk group: FIR, n = 781 (44.5%); MIR, n = 252 (14.4%); and UIR, n = 721 (41.1%). Mean age was 71 years (range 47-86). Mean PSA was 10.4 ng/ml (range 6-20). The median radiotherapy dose was 74 Gy, with mean doses of 72.5 Gy (FIR), 73.4 Gy (MIR), and 72.8 Gy (UIR). Most patients (88%) received ADT for a median of 7.1 months. By risk group (FIR, MIR, UIR), ADT rates were, respectively, 88.9, 86.5, and 86.9%. Only patients with ≥ 24 months of follow-up post-EBRT were included in the survival analysis (n = 1294). At a median follow-up of 52 months (range 24-173), respective 5- and 10-year outcomes were: OS 93.6% and 79%; BRFS 88.9% and 71.4%; DFS 96.1% and 89%; CSS 98.9% and 94.6%. Complication rates (≥ grade 3) were: acute genitourinary (GU) 2%; late GU 1%; acute gastrointestinal (GI) 2%; late GI 1%. There was no significant association between risk group and BRFS or OS. However, patients with favourable-risk disease had significantly better 5- and 10-year DFS than patients with UIR: 98.7% vs. 92.4% and 92% vs. 85.8% (p = 0.0005). CSS was significantly higher (p = 0.0057) in the FIR group at 5 (99.7% vs. 97.3%) and 10 years (96.1% vs. 93.4%). On the multivariate analyses, the following were significant predictors of survival: ADT (BRFS and DFS); dose ≥ 74 Gy (BRFS); age (OS). CONCLUSIONS This is the first nationwide study in Spain to report long-term outcomes of patients with intermediate-risk PCa treated with EBRT. Survival outcomes were good, with a low incidence of both acute and late toxicity. Patients with unfavourable risk characteristics had significantly lower 5- and 10-year disease-free survival rates. ADT and radiotherapy dose ≥ 74 Gy were both significant predictors of treatment outcomes.

Abstract
The aim of this study was to examine the effect of a pepsin egg white hydrolysate (EWH) on metabolic complications using a high-fat/high-dextrose diet-induced Metabolic Syndrome (MetS) experimental model. Male Wistar rats were divided into 4 groups which received: standard diet and water (C), standard diet and a solution with 1 g kg-1 day-1 of EWH (CH), high-fat/high-dextrose diet and water (MS), and high-fat/high-dextrose diet and a solution with 1 g kg-1 day-1 of EWH (MSH). EWH consumption normalized body weight gain; abdominal obesity and peripheral neuropathy developed in MetS animals, and adipose tissue and liver weight, as well as plasma glucose were reduced. Oxidative stress and inflammation biomarkers were normalized in MSH animals. In conclusion, the oral administration of EWH could be used as a functional food ingredient to improve some complications associated with MetS induced by unhealthy diets.

Abstract
PURPOSE Gastroenteropancreatic neuroendocrine tumors are a heterogeneous group of low incidence neoplasms characterized by a low proliferative activity and slow growth. Their response to targeted therapies is heterogeneous and often does not lead to tumor shrinkage. Thus, evaluation of the therapeutic response should differ from other kind of tumors. METHODS To answer relevant questions about which techniques are best in the assessment of progression or treatment response a RAND/UCLA-based consensus process was implemented. Relevant clinical questions were listed followed by a systematic search of the literature. The expert panel answered all questions with recommendations, combining available evidence and expert opinion. Recommendations were validated through a questionnaire and a participatory meeting. RESULTS Expert recommendations regarding imaging tools for tumor assessment and evaluation of progression were agreed upon. Available imaging techniques were reviewed and recommendations for best patient monitoring practice and the best way to evaluate treatment response were formulated.

Abstract
There is a lack of longitudinal data linking physical inactivity and chronic diseases among Mexicans. Objective. To examine the relationship between total, leisure and occupational moderate-to-vigorous physical activity (MVPA) and incidence of type II diabetes (T2D) and hypertension in the Mexico City Diabetes Study. Study design and population. A prospective cohort study was conducted from 1989 to 2009 among 2282 men and non-pregnant women residing in six low-income neighborhoods in Mexico City. Main outcome. Incidence of T2D and hypertension. Results. After controlling for confounders, <1 MET/min/week of MVPA during leisure time was associated with higher risk of hypertension (HR 1.29, CI 95% 1.01, 1.66) and T2D (HR 1.31 CI 95% 1.00, 1.74). In addition, accumulating <1 MET/min/week of occupational MVPA was associated with higher risk of hypertension (HR 1.47, CI 95% 1.13, 1.90). Conclusion. The absence of leisure and occupational MVPA was associated with an increased risk of hypertension. However, no associations were found between occupational MVPA and T2D.

Abstract
OBJECTIVE Reducing the time required for diagnosis is one of the major challenges to improving and accelerating the management of patients. The aim of this work is to describe an organizational innovation in the management of patients with hepatobiliary or pancreatic diseases, and to report the initial results. MATERIALS AND METHODS A multidisciplinary and multi-professional working group designed and instituted a patient-centered organizational system that optimizes the investigation of liver and pancreatic diseases, in order to achieve diagnosis in one day. From January 2017 to June 2017, all patients referred for consultation for hepatobiliary or pancreatic pathology were included in this new management pathway. Data were collected prospectively in a standardized form. RESULTS Fifty-six patients with hepatobiliary or pancreatic disease were evaluated in the program during dedicated slots over a total of 20 days. Of these, four patients underwent evaluation in the program twice. The average number of patient slots in the program was three per day (range: 1-5). An additional computed tomography (CT) and/or magnetic resonance imaging (MRI) was required in 23 (41.7%) of the visits. These imaging studies were performed the same day, including nine patients who required both types of imaging (16.7% of cases). "One-day diagnosis" established an accurate diagnosis by the end of the day in 49 patient encounters (81.7%). Overall assessment of this organization was considered excellent by 46 (83%) of patients. CONCLUSION An organizational innovation has made it possible to effectively diagnose hepatobiliary or pancreatic pathology within one day in the majority of cases, with good patient satisfaction. It is now necessary to evaluate the medico-economic aspect of this organization, and more generally to develop a methodology for multidimensional evaluation of organizational innovations.

Abstract
OBJECTIVE To explore the potential relationship between erectile dysfunction (ED), low testosterone levels, and the Charlson Comorbidity Index (CCI). MATERIAL AND METHODS Cross-sectional study on patients referred to the andrology unit in 7 Spanish centers. The ED was diagnosed and graded using the International Index of Erectile Function (IIEF-5) score. Total testosterone, the prevalence of each comorbidity, and the CCI were compared between patients with different grades of ED. Besides, the correlation between total testosterone and the CCI score, the influence of each comorbidity, and the ED severity on the CCI was assessed in a multiple linear regression. RESULTS The study included 430 men with a mean age of 61 years. The mean CCI was 3.5, and mean total testosterone 15.2 nmol/L; 389 (91%) subjects had some grade of ED: 97 (23%) mild, 149 (35%) mild-to-moderate, 86 (20%) moderate, and 57 (13%) severe. The increase in ED severity was significantly associated with a decrease in total testosterone (P=.002), and an increase in the CCI score (P<.001). Testosterone levels were significantly lower in patients with obesity, diabetes, hypercholesterolemia, and hypertriglyceridemia (P<.05). However, only the prevalence of diabetes and hypertension was significantly associated with the severity of ED. The multivariate analysis including variables related to all assessed comorbidities, total testosterone levels, and the DE severity significantly predicted the CCI score (P<.001, R2=.426). The severity of ED significantly contributed to this model (P=.011), but total testosterone did not (P=.204). CONCLUSIONS The CCI is significantly associated with the ED severity, but it shows a weak correlation with the testosterone levels.

Abstract
INTRODUCTION The lymphocyte positional parameters included in Sysmex XN have been suggested as useful means to differentiate lymphoproliferative disorders (LPD), mononucleosis syndrome (MNS) and other lymphocytoses. METHODS We evaluated Sysmex XN analysers, which supply 6 lymphocyte positional parameters that can be measured in the WDF scattergram: LY-X, LY-Y, LY-Z, LY-WX, LY-WY and LY-WZ. RESULTS We collected 301 samples from normal controls, polyclonal lymphocytosis, MNS and LPD. MNS and monoclonal expansion of T granular lymphocyte (T-GL) diagnostic groups accumulated higher numbers of significant differences in the mean values in comparison with the other groups. We propose a new algorithm that can differentiate T-GL cases from other diagnostic groups with an SE of 67.5%, an SP of 98.2%, a PPV of 87.1% and an NPV of 94.3%. Another algorithm showed its efficiency to differentiate MNS cases from other diagnostic groups with an SE of 63.6%, an SP of 97.5%, a PPV of 70.0% and an NPV of 96.7%. In 38.5% of all cases, the analyser did not generate any morphologic flag. Abnormal results in lymphocyte positional parameters were useful to detect 72.5% of these samples. CONCLUSION The lymphocyte positional parameters provided by Sysmex XN analysers are useful to differentiate expansions of T-GLs from other LPD and to differentiate MNS cases from other diagnostic groups. In addition, these parameters are very useful for detecting changes in the lymphocytes that make it necessary to review blood smears in samples without morphological flagging.

Abstract
Incorporation of pseudoisocytidine (psC), a neutral analogue of protonated cytidine, in i-motifs has been studied by spectroscopic methods. Our results show that neutral psC:C base pairs can stabilize i-motifs at neutral pH, but the stabilization only occurs when psC:C base pairs are located at the ends of intercalated C:C+ stacks. When psC occupies central positions, the resulting i-motifs are only observed at low pH and psC:C+ or psC:psC+ hemiprotonated base pairs are formed instead of their neutral analogs. Overall, our results suggest that positively charged base pairs are necessary to stabilize this non-canonical DNA structure.

Abstract
IntroductionAnimal hoarding is considered an under-reported problem, which affects the welfare of both people and animals. Few reports on animal hoarding are available in scientific literature, particularly outside North America.ObjectivesWe designed a study to analyse cases of animal hoarding in Catalonia.AimsWe wanted to expose the presence and consequences of this disorder in our area and to check for cross-cultural similarities with previous studies in other countries.MethodsData was obtained retrospectively from 23 case reports of animal hoarding in Catalonia collected by city councils and the Catalonian police from 1992 to 2015.ResultsThirty-three people (20 women and 13 men) and 1521 animals, mainly dogs and cats, were involved. Most cases (n = 13) involved a sole animal hoarder. Most cases (n = 14) were chronic (lasting longer than 5 years). Object hoarding co-morbidity was found in most cases (n = 17). All hoarders were over 40-years-old, with half of them aged over 65. Only in 4 cases was an intervention by the healthcare system reported. Most of the hoarders (9 out of 13) actively opposed animal removal. In more than 50% of cases, the hoarder's personal care, health and financial situation were precarious. No awareness of the impaired welfare of the animals was found in most cases.ConclusionsTo the author's knowledge, this is the first study on animal hoarding in Catalonia and one of the few available in Europe. Our results are aligned with previous research, adding evidence of cross-cultural common elements of animal hoarding.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
INTRODUCTION To date, no formal study has been published regarding how Colombian patients with skin disorders could be affected according to their perception of disease. OBJECTIVE To determine the impact in quality of life of skin diseases in a Colombian population. METHODS This multicenter study included patients with skin disease from almost the whole country. Individuals >18 years old; of any gender; with any skin disease and who signed informed consent, were included. We applied the Colombian validated version of the Skindex-29 instrument. RESULTS A total of 1896 questionnaires had sufficient information for the analyses. No significant differences in sociodemographic characteristics of patients who returned the questionnaire incomplete vs. complete, were found. Participants mean age was 41.5 years. There were no statistical differences in men vs. women regarding the global (p=0.37), symptoms (p=0.71) and emotions (p=0.32) domains, whereas statistical differences were found in the function domain (p=0.04; Mann-Whitney U test). Psoriasis, contact dermatitis, atopic dermatitis, urticaria, hair disorders, Hansen's disease, scars, hyperhidrosis and genital human papillomavirus disease scored the highest. LIMITATIONS Skindex-29 score variability as a result of differences in the location of the skin lesions, their inflammatory or non-inflammatory nature, and the start of therapy. CONCLUSIONS Even the most localized or asymptomatic skin lesion in our population leads to a disruption at some level of patient's wellness. This study adds well supported scientific data of the burden of skin diseases worldwide.

Abstract
PURPOSE Roughly two-thirds of early breast cancer cases are associated with negative axillary nodes and do not benefit from axillary surgery at all. Accordingly, there is an ongoing search for non-surgical staging procedures to avoid lymph-node dissection or sentinel node biopsy (SNB). Non-invasive imaging techniques with very high sensitivity (Se) and negative predictive value (NPV) could eventually replace SNB. We aimed to establish the role of axillary US and MRI, alone or in combination, associated with ultrasound-guided fine-needle aspiration biopsy (US-FNAB) in the prediction of axillary node involvement. METHODS/PATIENTS Between January 2003 and September 2015, we included 1505 of the 1538 breast cancer patients attending our centres. All patients had been referred from a single geographical area. Axillary US, magnetic resonance imaging and ultrasound-guided fine-needle aspiration biopsy (US-FNAB) were performed if required. RESULTS 1533 axillary US examinations and 1351 axillary MRI studies were analyzed. For axillary US, Se, Specificity (Sp), Positive Predictive Value (PPV), and NPV were 47.5, 93.6, 82.5, and 73.8%, respectively. For axillary MRI, corresponding values were 29.8, 96.6, 84.9, and 68.4%. When both tests were combined, Sp and PPV slightly improved over individual tests alone. US-FNAB showed a 100% Sp and PPV, with a Se of 80%. CONCLUSION We may confidently state that axillary US and US-FNAB have to be included in the preoperative work-up of breast cancer patients.

Abstract
The ability of the human isolate Lactobacillus fermentum UCO-979C to form biofilm and synthesize exopolysaccharide on abiotic and biotic models is described. These properties were compared with the well-known Lactobacillus casei Shirota to better understand their anti-Helicobacter pylori probiotic activities. The two strains of lactobacilli synthesized exopolysaccharide as detected by the Dubois method and formed biofilm on abiotic and biotic surfaces visualized by crystal violet staining and scanning electron microscopy. Concomitantly, these strains inhibited H. pylori urease activity by up to 80.4% (strain UCO-979C) and 66.8% (strain Shirota) in gastric adenocarcinoma (AGS) cells, but the two species showed equal levels of inhibition (~84%) in colorectal adenocarcinoma (Caco-2) cells. The results suggest that L. fermentum UCO-979C has probiotic potential against H. pylori infections. However, further analyses are needed to explain the increased activity observed against the pathogen in AGS cells as compared to L. casei Shirota.

Abstract
BACKGROUND Studies in adults show that central obesity increases the likelihood of Type 2 diabetes (T2DM). OBJECTIVE To determine the association between waist circumference (WC) and non-traditional risk factors such as magnesium (Mg), phosphorus, and uric acid in indigenous children living at high altitudes. METHODS A total of 354 (166 M) indigenous school children, aged 9.6 + 2.3 years, were enrolled in a cross-sectional study in November 2011. Central obesity was defined as WC > 90th percentile according to age and sex. Low Mg and phosphorus levels were defined as serum Mg <1.8 mg/dL and phosphorus <2.4 mg/dL . Hyperuricemia was defined as serum uric acid > 7 mg/dL. RESULTS The prevalence of central obesity was 6.8% (24/354). None of the children had hyperuricemia or low P levels. HypoMg was identified in 21.7% (57/263). There was a significant association between WC (z-score) and Mg (r-015), uric acid (r0.28), phosphorus (r-0.30), HOMA-IR (r0.49), Triglycerides (r0.24), and HDL-C (r0.24). However, calcium, sodium, and potassium were not significantly associated with WC. As z-WC quartiles increased Mg and phosphorus levels significantly decreased, whereas uric acid levels increased. Multiple linear regression analysis showed that z-WC was associated significantly and directly with uric acid (B0.31), triglycerides (B0.004), and HOMA-IR (B0.35); and inversely with Mg (B-0.83) and phosphorus (B-0.25), adjusted for confounding variables (R2 0.34). CONCLUSION Our results indicate that central obesity was significantly and inversely associated with Mg and phosphorus and directly with uric acid in indigenous school children. Supplementation with Mg and/or phosphorus could prevent future cardiovascular disease. Prospective and randomized studies should be performed to confirm these findings.
