Abstract
Introduction The COVID-19 pandemic drastically changed the daily routine of all healthcare systems worldwide, and endoscopy units were no exception. Endoscopic exams were considered to have a high risk of transmission, and therefore, the safety of endoscopy units and the consequent need for pre-endoscopy SARS-CoV-2 screening were questioned early on. The aim of our study was to assess the safety of endoscopy units during the COVID-19 pandemic, as well as the effectiveness/necessity for SARS-CoV-2 screening prior to endoscopies. Material and Methods This is a retrospective and single-center study carried out in a Portuguese tertiary hospital. All patients who underwent endoscopic procedures between September 1, 2020 and February 28, 2021 were included. The pre-endoscopy screening consisted of a specific questionnaire or a RT-PCR test for SARS-CoV-2 (nasal and oropharyngeal swab). Data were obtained through patient's clinical records and the Trace COVID platform. Results A total of 2,166 patients were included. Patients had a mean age of 61.8 years and were predominantly male (56.2%, n = 1,218). Eighty-one (3.7%) patients had previous SARS-CoV-2 infection, with a median difference of 74 days (IQ 40.5:160.5) between infection and endoscopy. Most patients (70.2%, n = 1,521) underwent PCR screening for SARS-CoV-2 up to 72 h before the procedure, with the remaining patients (29.8%, n = 645) answering a questionnaire of symptoms and risk contacts up to 3 days before endoscopy. Of the patients who underwent RT-PCR screening for SARS-CoV-2, 21 (1.4%) tested positive, and all were asymptomatic at the time of the screening. The evaluation for SARS-CoV-2 infection up to 14 days after the endoscopic exams identified 9 positive patients (0.42%) for SARS-CoV-2. The median difference in days between endoscopy and the diagnosis of infection was 10 days. Discussion/Conclusion Pre-endoscopy screening with RT-PCR test for SARS-CoV-2 identified a very small number of patients with COVID-19 infection as well as patients with COVID-19 infection in the following 14 days. Therefore, the risk of infection in endoscopy units is negligible if screening of symptoms and risk contacts is applied and individual protective equipment is used.

Abstract
Empyema necessitans is a rare entity that consists on the development of an abscess that begins in the pleural space and then extends to the adjacent tissues. This case shows a rare and very late complication of a total pneumonectomy, emphasizing the importance of the multidisciplinary approach and the potential of endoscopic therapy with over-the-scope clips.

Abstract
Background and Aims Colonoscopy is effective to detect and remove colorectal lesions. However, after a negative colonoscopy, cancers could be detected during the interval follow-up. This study was designed to identify characteristics and risk factors for postcolonoscopy colorectal cancer - interval type. Methods Medical records of individuals who were newly diagnosed with colorectal cancer between January 2018 and December 2019 were reviewed. Clinical, demographic, and endoscopic variables were analyzed. Those with the diagnosis of colorectal cancer between two consecutive colonoscopies performed within the appropriated surveillance range were considered to have postcolonoscopy colorectal cancer - interval type. A comparison between the group of patients with non-postcolonoscopy colorectal cancer - interval type and the group of patients with postcolonoscopy colorectal cancer - interval type was then performed. Results During the study period, 491 patients were newly diagnosed with colorectal cancer. Among them, 61 (12.4%) had postcolonoscopy colorectal cancer - interval subtype. Postcolonoscopy colorectal cancer - interval type was three times more prevalent on the proximal colon (p = 0.014) and was associated with the presence of two or more cardiovascular risk factors (aOR = 4.25; p = 0.016), cholecystectomy in the past (aOR = 10.09; p = 0.019), and family history of colorectal cancer on a first-degree relative (aOR = 4.25; p = 0.006). Moreover, isolated cardiovascular risk factors revealed a protective effect for the absence of all cardiovascular risk factors (aOR = 20; p = 0.034). The ROC curve associated with the multivariate model revealed a predictive power of 77.8% (p < 0.001). Conclusions Postcolonoscopy colorectal cancer - interval type is more common in the proximal colon and in patients with a family history (first-degree relative) of colorectal cancer, two or more cardiovascular risk factors, and a history of cholecystectomy. All of these are easily detectable in clinical practice and may be of extreme importance in the control of postcolonoscopy colorectal cancer in the near future.

Abstract
A 50-year-old male was referred to a Gastroenterology appointment after a screening colonoscopy with a 25mm exophytic lesion, with a depressed central area, on the transverse colon. Histologic examination of the biopsy specimen showed low-grade dysplasia. The patient was submitted to a new colonoscopy and what was seen was a flat lesion with central depression, with no lift-sign (Figure 1a and 1b) and, therefore, endoscopic resection was not performed. New endoscopic biopsies were taken and showed no dysplasia.

Abstract
Every year, the VISion Understanding and Machine intelligence (VISUM) summer school runs a competition where participants can learn and share knowledge about Computer Vision and Machine Learning in a vibrant environment. 2021 VISUM's focused on applying those methodologies in fashion. Recently, there has been an increase of interest within the scientific community in applying computer vision methodologies to the fashion domain. That is highly motivated by fashion being one of the world's largest industries presenting a rapid development in e-commerce mainly since the COVID-19 pandemic. Computer Vision for Fashion enables a wide range of innovations, from personalized recommendations to outfit matching. The competition enabled students to apply the knowledge acquired in the summer school to a real-world problem. The ambition was to foster research and development in fashion outfit complementary product retrieval by leveraging vast visual and textual data with domain knowledge. For this, a new fashion outfit dataset (acquired and curated by FARFETCH) for research and benchmark purposes is introduced. Additionally, a competitive baseline with an original negative sampling process for triplet mining was implemented and served as a starting point for participants. The top 3 performing methods are described in this paper since they constitute the reference state-of-the-art for this particular problem. To our knowledge, this is the first challenge in fashion outfit complementary product retrieval. Moreover, this joint project between academia and industry brings several relevant contributions to disseminating science and technology, promoting economic and social development, and helping to connect early-career researchers to real-world industry challenges.

Abstract
BACKGROUND For the prevention of cardiovascular diseases, the practice of physical exercises is an effective strategy in improving or maintaining cardiorespiratory health; however, a lack of time is a barrier to access and interval training appears as possible facilitator. This study aims to compare the effects of two interval training protocols on cardiac autonomic modulation in healthy women. METHODS we conducted a randomized clinical trial with 43 women with a mean age of 29.96 ± 6.25 years, allocated into two groups; high-intensity interval training (HIIT) consisting of four four-minute high-intensity sprints interspersed with three minutes of active recovery and the Sprint interval training (SIT) with four 30-s sprints all-out, interspersed with four minutes of recovery (active or passive). RESULTS the HIIT group presented better results for the patterns without variation (0V) variables (p = 0.022); Shannon entropy (p = 0.004) Conditional Entropy (p = 0.025). However, there was a significant group effect for some variables, Oxygen Volume (VO2) (p = 0.004), Square root of the mean quadratic differences between the adjacent normal R-R intervals (p = 0.002) and standard deviation of all normal R-R intervals recorded in a time interval (p = 0.003), demonstrating an improvement independent of the protocol. CONCLUSION we conclude that eight weeks of interval training were able to produce positive effects on cardiac autonomic modulation in healthy women, with better results for HIIT in this population.

Abstract
BACKGROUND Suicide is one of the main causes of excess of premature death in psychotic patients. Published studies found that suicide risk begins in ultra-high risk of psychosis and continues in early years of the disease. Previous studies identifying predictive and risk factors associated with suicidality in first-episode psychosis (FEP) are highly inconsistent. Also, there are relatively few longitudinal studies on suicidal behaviour in FEP. The aim of this study was to examine prevalence, evolution and predictors of suicidal behaviour at baseline and the 12-month follow-up in patients presenting with FEP. METHODS One hundred and eighteen patients presenting with FEP were recruited from two early psychosis units in Portugal. A comprehensive assessment examining socio-demographic and clinical characteristics was administered at baseline and the 12-month follow-up. Odds ratio were calculated using logistic regression analyses. McNemar test was used to evaluate the evolution of suicidal behaviour and depression prevalence from baseline to 12 months of follow-up. RESULTS Follow-up data were available for 60 participants from the 118 recruited. Approximately 25.4% of the patients had suicidal behaviour at the baseline evaluation, with a significant reduction during the follow-up period to 13.3% (p = 0.035). A multivariate binary logistic regression showed that a history of suicidal behaviour and depression at baseline independently predicted suicidal behaviour at baseline, and a history of suicidal behaviour and low levels of total cholesterol predicted suicidal behaviour at the 12-month follow-up. A significant proportion of patients also had depression at the baseline evaluation (43.3%), with the last month of suicidal behaviour at baseline independently predicting depression at this time. CONCLUSIONS The findings of our study indicate that suicidal behaviour was prevalent on the year after FEP. Patients with a history of suicidal behaviour, depression at baseline and low levels of cholesterol should undergo close evaluation, monitoring and possible intervention in order to reduce suicide risk in the early phases of psychosis.

Abstract
Experiments on neutral gas-phase nucleosides are often complicated by thermal lability. Previous mass spectrometry studies of nucleosides have identified enhanced relative production of nucleobase ions (e.g. uracil+ from uridine) as a function of desorption temperature to be the critical indicator of thermal decomposition. On this basis, the present multi-photon ionization (MPI) experiments demonstrate that laser-based thermal desorption is effective for producing uridine, 5-methyluridine, and 2′-deoxyuridine targets without thermal decomposition. Our experiments also revealed one notable thermal dependence: the relative production of the sugar ion C5H9O4+ from intact uridine increased substantially with the desorption laser power and this only occurred at MPI wavelengths below 250 nm (full range studied 222–265 nm). We argue that this effect can only be rationalized plausibly in terms of changing populations of different isomers, tautomers, or conformers in the target as a function of the thermal desorption conditions. Furthermore, the wavelength threshold behavior of this thermally-sensitive MPI channel indicates a critical dependence on neutral excited state dynamics between the absorption of the first and second photons. The experimental results are complemented by density functional theory (DFT) optimizations of the lowest-energy structure of uridine and two further conformers distinguished by different orientations of the hydroxymethyl group on the sugar part of the molecule. The energies of the transitions states between these three conformers are low compared with the energy required for decomposition. This work reveals the first experimental evidence supporting isomer-dependence in the radiation response of a nucleoside.![]()

Abstract
Abstract
Funding Acknowledgements
Type of funding sources: None.
Background
Syncope is a common reason for emergency department attendance. This entity may be associated with significant morbidity and mortality and its differential diagnosis is not straightforward. Arrhythmic causes include tachycardia and bradycardia; the later may require pacemaker implantation. Many hospitals lack a dedicated syncope unit to approach these patients. So, patients’ triage may fall into medical or surgical (trauma) areas.
Purpose
To describe the population of patients that required permanent pacemaker implantation in the year of 2019, particularly those who had a previous visit to the emergency department with syncope or presyncope.
Methods
Single-center descriptive analysis of patients that implanted a permanent pacemaker in 2019 (inclusion criteria). Additional information was collected in patients with emergency department visits in the 365 days that preceded the device implantation.
Results
In 2019, a total of 398 patients were admitted for pacemaker implantation in 2019, 55% male (n = 218), 45% female (n = 180), with mean age of 79 years. Regarding indications for pacing, 41% (n= 156) had complete atrioventricular (AV) block, 26% (n = 105) had a second degree AV block, 16% (n = 64) had sinus node dysfunction, 13.5% (n = 53) had atrial fibrillation with slow ventricular conduction, and 3.5% (n = 14) had other indications.
Twenty-two percent (n = 88) of patients had a previous visit to the emergency department (other than the ones that triggered the pacemaker implantation) with complaints of syncope (60%) or presyncope (40%). Of these, 73% (n = 64) were referred to a medical area and 27% (n = 24) were referred to a surgical area; 40 patients presented with traumatic lesions (68% cranioencephalic trauma and 32% other traumas). Of the 88 patients, only 67% (n = 59) performed an ECG and only 23% (n = 20) were referred for observation by a cardiologist in the emergency department.
Comparing medical and surgical triage, we observe that patients referred to the surgical area were less likely to perform an ECG and to be observed by a cardiologist (with statistical significance).
Conclusions
Our work describes a common problem in hospitals without dedicated syncope evaluation units. As all the patients ended up implanting a pacemaker, it is interesting to observe that 22%of these had a "warning" visit to the emergency and 33% of the last did not get and ECG. Also, trauma-oriented approaches result in a lower likelihood of performing a complete evaluation of the cause of the syncopal event. This analysis highlights the need for a comprehensive and multidisciplinary approach of patients presenting with syncope and presyncope to promote early identification and treatment of arrhythmic causes, reducing patient morbidity and healthcare costs.

Abstract
BACKGROUND There is growing evidence about the relationship between sleep quality (SQ) and disease activity in inflammatory bowel disease (IBD). This study aimed to identify the prevalence of sleep disturbance in IBD and its predictive factors and to assess its association with worse outcome. METHODS IBD patients were prospectively enrolled. Clinical activity, inflammatory activity (high C-reactive protein or fecal calprotectin), and SQ (assessed using the Pittsburgh Sleep Quality Index) were evaluated, and logistic regression was used to identify predictors of poor SQ at baseline. The development of disability or disease progression at 6 months (surgery, hospitalization, development of stenosis, penetrating or perianal disease, steroid dependency, or start/change immunosuppression) was compared between patients with and without poor SQ. RESULTS Two hundred and five patients were enrolled, with 44.9% (n = 92) reporting poor SQ. On multivariate analysis, current smoking (OR 2.80), extraintestinal manifestations (OR 2.68), clinical activity (OR 3.31), and inflammatory activity (OR 4.62) were predictive factors of poor SQ. Cox proportional hazards model showed that poor SQ was predictive of worse prognosis at 6 months (HR 2.470). CONCLUSION There is a high prevalence of poor SQ in IBD patients, highlighting the importance of its inclusion in patient-reported outcomes. Sleep disturbance seems to have prognostic value in IBD.

Abstract
AIM There is currently no national plan for early intervention in first-episode psychosis in Portugal. Consequently, there is some heterogeneity in the evaluation and treatment of first-episode psychosis across the country. The aim of this article is to provide a complete description of the early intervention programme Programa de Intervenção nas Fases Iniciais da Psicose (PROFIP) in Lisbon, a pioneering team in Portugal for treating first-episode psychosis (FEP) patients. We also describe the baseline socio-demographic and clinical data obtained from new patients over a 1-year period. PROFIP programme accepts all cases of FEP, taking a transdiagnostic approach. METHODS Description of PROFIP programme and baseline socio-demographic and clinical data obtained from new patients over a 1-year period. RESULTS The team was constituted to provide early detection, treatment and support to people aged 16 to 35 years with affective and non-affective FEP. Over a 1-year period, 39 patients were included in the PROFIP programme. The majority of patients were young male patients with a diagnosis of non-affective psychosis, and with 56% of patients reporting cannabis use. Patients received pharmacological and psychosocial interventions based on evidence and individual needs. CONCLUSIONS Our team allowed young people with early psychosis to receive effective care. We do need improvements, namely in referrals and the education of health professionals. More teams in our country should be constituted, allowing larger numbers of patients with early psychosis to be treated by specialized teams.

Abstract
The Plectranthus genus is commonly used in traditional medicine due to its potential to treat several illnesses, including bacterial infections and cancer. As such, aiming to screen the antibacterial and cytotoxic activities of extracts, sixteen selected Plectranthus species with medicinal potential were studied. In total, 31 extracts obtained from 16 Plectranthus spp. were tested for their antibacterial and anticancer properties. Well diffusion method was used for preliminary antibacterial screening. The minimum inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) values of the five most active acetonic extracts (P. aliciae, P. japonicus, P. madagascariensis var. “Lynne”, P. stylesii, and P. strigosus) were determined. After preliminary toxicity evaluation on Artemia salina L., their cytotoxic properties were assessed on three human cancer cell lines (HCT116, MCF-7, and H460). These were also selected for mechanism of resistance studies (on NCI-H460/R and DLD1-TxR cells). An identified compound—parvifloron D—was tested in a pair of sensitive and MDR-Multidrug resistance cancer cells (NCI-H460 and NCI-H460/R) and in normal bronchial fibroblasts MRC-5. The chemical composition of the most active extract was studied through high performance liquid chromatography with a diode array detector (HPLC-DAD/UV) and liquid chromatography–mass spectrometry (LC–MS). Overall, P. strigosus acetonic extract showed the strongest antimicrobial and cytotoxic potential that could be explained by the presence of parvifloron D, a highly cytotoxic diterpene. This study provides valuable information on the use of the Plectranthus genus as a source of bioactive compounds, namely P. strigosus with the potential active ingredient the parvifloron D.

Abstract
Abstract
Objectives
Imaging-guided needle biopsy is a reliable alternative to surgical biopsy in the diagnosis of breast pathologies. However, false-positive results are common. Rad-Path correlation is crucial in identifying such results, thus allowing appropriate diagnosis and follow-up. We report our experience of Rad-Path correlation results in a community teaching hospital.
Methods
The tumor board data at Danbury Hospital were searched for Rad-Path conferences held from 2013 to 2018. Benign breast biopsies obtained from SNOMED, a monthly pathology list of imaging-guided needle biopsies performed at Danbury Hospital, were presented at these conferences. Data from the list were used for this research. Fibroadenoma cases were excluded in the analysis. The total number of cases presented and proportion of concordant and discordant cases were reviewed. Data on discordant cases were further reviewed to determine the reasons for discordance and follow-up outcomes.
Results
In the last 6 years, 64 Rad-Path meetings were held. A total of 393 benign breast biopsies were presented. Of the 393 cases, 24 (6.1%) were discordant. The radiologic findings for the discordant cases were as follows: mass/nodule, 15; calcifications, 7; linear nonmass enhancement, 1; and duct debris, 1. All the suspicious radiologic findings received a benign pathologic diagnosis. These discrepancies in Rad-Path findings were discussed in detail during the multidisciplinary tumor board. Out of 24 discordant cases, 5 (20.8%) were reviewed by the sign-out radiologist and their BI-RADS updated accordingly, another 5 (20.8%) cases had excisional biopsies, 9 (37.5%) cases were recommended for 6- or 12-month radiology follow-up, and the remaining 5 (20.8%) cases were lost to follow-up.
Conclusion
Rad-Path correlation is a key component of imaging-guided breast biopsy reporting. It facilitates detection of discordant radiologic and pathologic findings, and it prevents misdiagnosis and unnecessary repeat interventional procedures. This practice ultimately results in improved patient management.

Abstract
Pancreatic cancer remains one of the most lethal cancers worldwide, with an extremely poor prognosis. This cancer is considered the 5th leading cause of cancer related death. The median survival after diagnosis is generally 2-8 months and five-year survival rate is less than 5%. In recent years, nanotechnology is emerging as a rising approach for drug delivery since it has opened up new landscapes in medicine through introduction of smart nanocarrier systems that can selectively deliver the therapeutic agent in a specific region and in appropriate levels, reducing the adverse side effects. This review covers the main delivery systems developed so far for anticancer drug delivery to the pancreas over a period of 20 years, from polymeric to lipidic-based nanosystems, with a particular emphasis on albumin as core material.

Abstract
PLA2G6-associated neurodegeneration (PLAN) and hereditary spastic paraplegia (HSP) are 2 groups of heterogeneous neurodegenerative diseases. In this study, we report PLA2G6 gene mutations in 3 families from Turkey, Morocco, and Romania. Two affected Turkish siblings presenting HSP adds the disease to PLAN phenotypes. They were homozygous for the PLA2G6 missense c.2239C>T, p.Arg747Trp variant and the ages of onset were 9 and 21. Parkinsonism, dystonia or cognitive decline were not the clinical elements in these patients contrary to the cases that has been previously reported with the same variant, however, iron accumulation was evident in their cranial magnetic resonance imaging. The Moroccan patient was homozygous for a novel missense c.1786C>T, p.Leu596Phe variant and the Romanian patient had 2 novel mutations; c.1898C>T, p.Ala633Val and c.1765_1768del, p.Ser589ThrfsTer76. Both of these patients conformed better to childhood onset PLAN with the age of onset at 4 and 7 years, respectively. Interestingly, all identified mutations were affecting the highly conserved patatin-like phospholipase domain of the PLA2G6 protein.

Abstract
Sistemas aquáticos que apresentam águas calmas e com região delimitada, por exemplo, lagoas, lagos e pântanos, são denominados ambientes lênticos. O Parque Carlos Alberto de Souza, localizado em Sorocaba-SP, é um dos parques existentes na cidade contendo lago artificial, onde habitam peixes, tartarugas e garças. É frequentado por crianças e adultos para lazer ou prática de exercícios. Sendo assim, uma boa qualidade de água é fundamental para a vida no lago. O objetivo deste trabalho foi analisar a qualidade da água, usando índices de qualidade adotados pela CETESB (Companhia de Tecnologia de Saneamento Ambiental). Os resultados apresentaram valor elevado de coliformes termotolerantes e baixa concentração de oxigênio. Considerando a ponderação dos parâmetros a água foi classificada como boa, porém o índice referente à presença de nutrientes classificou o corpo hídrico como hipertrófico, o que pode causar aflorações de algas e mortandades de peixes. Os resultados representam um alerta quanto à necessidade de monitoramento da qualidade dos ambientes lênticos e a necessitade de alertas à população que frequentam o ambiente.

Abstract
AIM: To evaluate the efficacy and safety of endoscopic sphincterotomy (EST) + endoscopic papillary large balloon dilation (EPLBD) vs isolated EST.
METHODS: We conducted a retrospective single center study over two years, from February 2010 to January 2012. Patients with large (≥ 10 mm), single or multiple bile duct stones (BDS), submitted to endoscopic retrograde cholangio-pancreatography (ERCP) were included. Patients in Group A underwent papillary large balloon dilation after limited sphincterotomy (EST+EPLBD), using a through-the-scope balloon catheter gradually inflated to 12-18 mm according to the size of the largest stone and the maximal diameter of the distal bile duct on the cholangiogram. Patients in Group B (control group) underwent isolated sphincterotomy. Stones were removed using a retrieval balloon catheter and/or a dormia basket. When necessary, mechanical lithotripsy was performed. Complete clearance of the bile duct was documented with a balloon catheter cholangiogram at the end of the procedure. In case of residual lithiasis, a double pigtail plastic stent was placed and a second ERCP was planned within 4-6 wk. Some patients were sent for extracorporeal lithotripsy prior to subsequent ERCP. Outcomes of EST+EPLBD (Group A) vs isolated EST (Group B) were compared regarding efficacy (complete stone clearance, number of therapeutic sessions, mechanical and/or extracorporeal lithotripsy, biliary stent placement) and safety (frequency, type and grade of complications). Statistical analysis was performed using χ2 or Fisher’s exact tests for the analysis of categorical parameters and Student’s t test for continuous variables. A P-value of less than 0.05 was considered statistically significant.
RESULTS: One hundred and eleven patients were included, 68 (61.3%) in Group A and 43 (38.7%) in Group B. The mean diameter of the stones was similar in the two groups (16.8 ± 4.4 and 16.0 ± 6.7 in Groups A and B, respectively). Forty-eight (70.6%) patients in Group A and 21 (48.8%) in Group B had multiple BDS (P = 0.005). Overall, balloon dilation was performed up to 12 mm in 10 (14.7%) patients, 13.5 mm in 17 (25.0%), 15 mm in 33 (48.6%), 16.5 mm in 2 (2.9%) and 18 mm in 6 (8.8%) patients, taking into account the diameter of the largest stone and that of the bile duct. Complete stone clearance was achieved in sixty-five (95.6%) patients in Group A vs 30 (69.8%) patients in Group B, and was attained within the first therapeutic session in 82.4% of patients in Group A vs 44.2% in Group B (P < 0.001). Patients submitted to EST+EPLBD underwent fewer therapeutic sessions (1.1 ± 0.3 vs 1.8 ± 1.1, P < 0.001), and fewer required mechanical (14.7% vs 37.2%, P = 0.007) or extracorporeal (0 vs 18.6%, P < 0.001) lithotripsy, as well as biliary stenting (17.6% vs 60.5%, P < 0.001). The rate of complications was not significantly different between the two groups.
CONCLUSION: EST+EPLBD is a safe and effective technique for treatment of difficult BDS, leading to high rates of complete stone clearance and reducing the need for lithotripsy and biliary stenting.

Abstract
Can markets assist by providing support for ecological restoration, and if so, under what conditions? The first step in addressing this question is to develop a consistent methodology for economic evaluation of ecological restoration projects. A risk analysis process was followed in which a system dynamics model was constructed for eight diverse case study sites where ecological restoration is currently being pursued. Restoration costs vary across each of these sites, as do the benefits associated with restored ecosystem functioning. The system dynamics model simulates the ecological, hydrological and economic benefits of ecological restoration and informs a portfolio mapping exercise where payoffs are matched against the likelihood of success of a project, as well as a number of other factors (such as project costs and risk measures). This is the first known application that couples ecological restoration with system dynamics and portfolio mapping. The results suggest an approach that is able to move beyond traditional indicators of project success, since the effect of discounting is virtually eliminated. We conclude that systems dynamic modelling with portfolio mapping can guide decisions on when markets for restoration activities may be feasible.

Abstract
This study investigated the relationships between children's secure base and emotion regulation, namely their behavioral strategies and emotional expressiveness, during different situational and social contexts in naturalistic settings. Fifty-five children ranging in age from 18 to 26 months of age and their mothers participated in this study. Children were exposed to three situational (fear, positive affect and frustration/anger) and two social (maternal constraint and involvement) contexts. Toddlers' behavioral strategies differed as function of emotion-eliciting context, maternal involvement and attachment quality. Emotional expressiveness varied as function of an interaction involving situational contexts, maternal involvement and children's attachment security.

Abstract
AIM: To evaluate small bowel cleansing quality, diagnostic yield and transit time, comparing three cleansing protocols prior to capsule endoscopy.
METHODS: Sixty patients were prospectively enrolled and randomized to one of the following cleansing protocols: patients in Group A underwent a 24 h liquid diet and overnight fasting; patients in Group B followed protocol A and subsequently were administered 2 L of polyethylene glycol (PEG) the evening before the procedure; patients in Group C followed protocol B and were additionally administered 100 mg of simethicone 30 min prior to capsule ingestion. Small bowel cleansing was independently assessed by two experienced endoscopists and classified as poor, fair, good or excellent according to the proportion of small bowel mucosa under perfect conditions for visualization. When there was no agreement between the two endoscopists, the images were reviewed and discussed until a consensus was reached. The preparation was considered acceptable if > 50% or adequate if > 75% of the mucosa was in perfect cleansing condition. The amount of bubbles was assessed independently and it was considered significant if it prevented a correct interpretation of the images. Positive endoscopic findings, gastric emptying time (GET) and small bowel transit time (SBTT) were recorded for each examination.
RESULTS: There was a trend favoring Group B in achieving an acceptable (including fair, good or excellent) level of cleansing (Group A: 65%; Group B: 83.3%; Group C: 68.4%) [P = not significant (NS)] and favoring Group C in attaining an excellent level of cleansing (Group A: 10%; Group B: 16.7%; Group C: 21.1%) (P = NS). The number of patients with an adequate cleansing of the small bowel, corresponding to an excellent or good classification, was 5 (25%) in Group A, 5 (27.8%) in Group B and 4 (21.1%) in Group C (P = 0.892). Conversely, 7 patients (35%) in Group A, 3 patients (16.7%) in Group B and 6 patients (31.6%) in Group C were considered to have poor small bowel cleansing (P = 0.417), with significant fluid or debris such that the examination was unreliable. The proportion of patients with a significant amount of bubbles was 50% in Group A, 27.8% in Group B and 15.8% in Group C (P = 0.065). This was significantly lower in Group C when compared to Group A (P = 0.026). The mean GET was 27.8 min for Group A, 27.2 min for Group B and 40.7 min for Group C (P = 0.381). The mean SBTT was 256.4 min for Group A, 256.1 min for Group B and 258.1 min for Group C (P = 0.998). Regarding to the rate of complete examinations, the capsule reached the cecum in 20 patients (100%) in Group A, 16 patients (88.9%) in Group B and 17 patients (89.5%) in Group C (P = 0.312). A definite diagnosis based on relevant small bowel endoscopic lesions was established in 60% of the patients in Group A (12 patients), 44.4% in Group B (8 patients) and 57.8% in Group C (11 patients) (P = 0.587).
CONCLUSION: Preparation with 2 L of PEG before small bowel capsule endoscopy (SBCE) may improve small bowel cleansing and the quality of visualization. Simethicone may further reduce intraluminal bubbles. No significant differences were found regarding GET, SBTT and the proportion of complete exploration or diagnostic yield among the three different cleansing protocols.

Abstract
Anthropometric characteristics, physical fitness and technical skills of under-19 (U19) soccer players were compared by competitive level (elite, n=95; non-elite, n=85) and playing position (goalkeeper, central defender, fullback, midfield, forward). Fitness tests included 5- and 30-m sprints, agility, squat jump (SJ) and countermovement jump (CMJ), strength and Yo-Yo intermittent endurance test level 2 (Yo-Yo IE2). Soccer-specific skills included ball control and dribbling. Independent of position, elite players presented more hours of training per year than non-elite players (d>1.2). Stature and body mass discriminated elite from non-elite players among goalkeepers and central defenders (d>0.6). Major differences were noted between elite and non-elite goalkeepers for SJ, CMJ, Yo-Yo IE2, and ball control (d>1.2). Elite central defenders performed better than their non-elite counterparts in SJ and ball control tests (d>1.2). Elite players presented better agility and Yo-Yo IE2 performances than non-elite players within all positional roles (d>0.6). In conclusion, U19 players differed in anthropometric characteristics, physical fitness and technical skills by competitive level within field positions.

Abstract
BACKGROUND/AIMS The Lewis Score (LS) can assess inflammatory activity on small bowel capsule endoscopy (SBCE). We aimed to evaluate the LS usefulness in the setting of suspected Crohn's Disease (CD). METHODS Retrospective single-center study including 56 patients undergoing SBCE for suspected CD. Patients were divided into three groups, according to clinical presentation: Group 1 (28 patients): suspected CD not supported by the International Conference on Capsule Endoscopy (ICCE) criteria; Group 2 (19 patients): suspected CD based on two ICCE criteria; Group 3 (9 patients): patients fulfilling three or more criteria. Inflammatory activity was assessed with the LS. The diagnosis of CD required a minimum follow-up of 6 months after SBCE, basing on clinical evaluation, endoscopic, histological, radiological, and/or biochemical investigations. RESULTS SBCE detected significant inflammatory activity (LS≥135) in 23 patients (41.1%), being 5 patients from Group 1 (17.8%), 11 from Group 2 (57.9%) and 7 from Group 3 (77.8%) (p<0.05). CD was diagnosed in 23 patients (41.1%): six patients from Group 1 (21.4%), 10 from Group 2 (52.6%) and 7 from Group 3 (77.8%) (p<0.05). CD was diagnosed in 82.6% of patients with significant inflammatory activity on CE (LS≥135), but in only 12.1% of those having a LS<135 (p<0.05). The LS Positive Predictive Value, Negative Predictive Value, Sensitivity and Specificity were 82.6%, 87.9%, 82.6% and 87.9%, respectively. CONCLUSIONS The LS may be a valuable diagnostic tool in the setting of suspected CD. Patients not fulfilling the ICCE criteria have lower LS and fewer are diagnosed with CD during follow-up.

Abstract
AIM: To assess the efficacy and safety of endoscopic papillary large balloon dilation after biliary sphincterotomy for difficult bile duct stones retrieval.
METHODS: Retrospective review of consecutive patients submitted to the technique during 18 mo. The main outcomes considered were: efficacy of the procedure (complete stone clearance; number of sessions; need of lithotripsy) and complications.
RESULTS: A total of 30 patients with a mean age of 68 ± 10 years, 23 female (77%) and 7 male (23%) were enrolled. In 10 patients, a single stone was found in the common bile duct (33%) and in 20 patients multiple stones (67%) were found. The median diameter of the stones was 17 mm (12-30 mm). Dilations were performed with progressive diameter Through-The-Scope balloons (up to 12, 15) or 18 mm. Complete retrieval of stones was achieved in a single session in 25 patients (84%) and in two sessions in 4 patients (13%). Failure occurred in 1 case (6%). Mechanical lithotripsy was performed in 6 cases (20%). No severe complications occurred. One patient (3%) had mild-grade post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis.
CONCLUSION: Endoscopic balloon dilatation with a large balloon after endoscopic sphincterotomy is a safe and effective technique that could be considered an alternative choice in therapeutic ERCP.

Abstract
The preservation of musical works produced in the past requires their digitalization and transformation into a machine-readable format. The processing of handwritten musical scores by computers remains far from ideal. One of the fundamental stages to carry out this task is the staff line detection. We investigate a general-purpose, knowledge-free method for the automatic detection of music staff lines based on a stable path approach. Lines affected by curvature, discontinuities, and inclination are robustly detected. Experimental results show that the proposed technique consistently outperforms well-established algorithms.
