Abstract
INTRODUCTION AND OBJECTIVES The optimal approach for persistent atrial fibrillation (AF) ablation remains unknown. In patients with persistent AF, we compared an ablation strategy based on pulmonary vein isolation (PVI) plus ablation of drivers (PVI+D), with a conventional PVI-only approach performed in a 1:1 propensity score-matched cohort. METHODS Drivers were subjectively identified using conventional high-density mapping catheters (IntellaMap ORION, PentaRay NAV or Advisor HD Grid), without dedicated software, as fractionated continuous or quasicontinuous electrograms on 1 to 2 adjacent bipoles, which were ablated first; and as sites with spatiotemporal dispersion (the entire cycle length comprised within the mapping catheter) plus noncontinuous fractionation, which were only targeted in patients without fractionated continuous electrograms, or without AF conversion after ablation of fractionated continuous electrograms. Ablation included PVI plus focal or linear ablation targeting drivers. RESULTS A total of 50 patients were included in each group (61±10 years, 25% women). Fractionated continuous electrograms were found and ablated in 21 patients from the PVI+D group (42%), leading to AF conversion in 7 patients. In the remaining 43 patients, 143 sites with spatiotemporal dispersion plus noncontinuous fractionation were targeted. Globally, AF conversion was achieved in 21 patients (42%). The PVI+D group showed lower atrial arrhythmia recurrences at 1 year of follow-up (30.6% vs 48%; P=.048) and at the last follow-up (46% vs 72%; P=.013), and less progression to permanent AF (10% vs 40%; P=.001). CONCLUSIONS Subjective identification and ablation of drivers, added to PVI, increased 1-year freedom from atrial arrhythmia and decreased long-term recurrences and progression to permanent AF.

Abstract
The implantation of percutaneous balloon expandable valves in native or patched right ventricular outflow tracts (nRVOT) is a challenging technique due to the diversity of anatomies and shapes, the large sizes, and the distensibility of the nRVOT, for which specific techniques have been developed. We present a single center experience with balloon expandable percutaneous pulmonary valves in nRVOT, describing the techniques used, complications observed, and a short-mid term follow-up.. This is a single center descriptive study of patients who underwent a percutaneous pulmonary valve implantation in a nRVOT with a balloon expandable pulmonary valve in our center between September 2012 and June 2022.. We implanted successfully 45 valves in 46 patients (20 Sapien and 25 Melody). Tetralogy of Fallot or pulmonary atresia with VSD were the main congenital heart disease (n = 32). All were pre-stented, 18 in a one step procedure. We used a Dryseal sheath in 13/21 Sapien. In 6 patients we used the anchoring technique, 5 with a very large nRVOT and one pyramidal nRVOT. In the 3.5 year follow-up 7 patients developed endocarditis and 3 required a valve redilation, no fractures were observed. PPVI of native RVOT with balloon expandable valves is feasible in a number of selected anatomies, including large or pyramidal nRVOT, using specific techniques, (presenting, LPA anchoring).

Abstract
BackgroundEndobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) is the technique of choice in the study of mediastinal and hilar lesions; however, it can be affected by the insufficiency of intact biopsy samples, which might decrease its diagnostic yield for certain conditions, thus requiring re-biopsies or additional diagnostic procedures such as mediastinoscopy when probability of malignancy remains high.ObjectivesOur objectives were to 1) attempt to reproduce this technique in the same conditions that we performed EBUS-TBNA, that is, in the bronchoscopy suite and under moderate sedation; 2) describe the method used for its execution; 3) determine its feasibility by accessing different lymph node stations applying our method; 4) analyze the diagnostic yield and its complications.MethodsProspective study of 50 patients who underwent EBUS-TBNA and EBUS-guided TMC in a single procedure using a 22-G TBNA needle and a 1.1 mm cryo-probe subsequently between January and August 2022. Patients with mediastinal lesions greater than 1 cm were recruited and EBUS-TBNA and TMC were performed in the same lymph node station.ResultsThe diagnostic yield was 82% and 96% for TBNA and transbronchial mediastinal cryobiopsy, respectively. Diagnostic yields were similar for sarcoidosis, while cryobiopsy was more sensitive than TBNA in lymphomas and metastatic lymph nodes. As for complications, there was no pneumothorax and in no case was there significant bleeding. There were no complications during the procedure or in the follow-up of these patients.ConclusionsTMC following our method is a minimally invasive, rapid, and safe technique that can be performed in a bronchoscopy suite under moderate sedation, with a higher diagnostic yield than EBUS-TBNA, especially in cases of lymphoproliferative disorders and mestastatic lymph nodes, or when more biopsy sample is needed for molecular determinations.

Abstract
The number of maps deposited in public databases (Electron Microscopy Data Bank, EMDB) determined by cryo-electron microscopy has quickly grown in recent years. With this rapid growth, it is critical to guarantee their quality. So far, map validation has primarily focused on the agreement between maps and models. From the image processing perspective, the validation has been mostly restricted to using two half-maps and the measurement of their internal consistency. In this article, we suggest that map validation can be taken much further from the point of view of image processing if 2D classes, particles, angles, coordinates, defoci, and micrographs are also provided. We present a progressive validation scheme that qualifies a result validation status from 0 to 5 and offers three optional qualifiers (A, W, and O) that can be added. The simplest validation state is 0, while the most complete would be 5AWO. This scheme has been implemented in a website https://biocomp.cnb.csic.es/EMValidationService/ to which reconstructed maps and their ESI can be uploaded.

Abstract
Introduction
Hepatic ones are some of the most described somatic complications in anorexia nervosa (AN) affected patients. They can be due to malnutrition, which is the more usual thing, or due to re-feeding. The first one can lead to more marked elevations of the hepatic enzymes, especially alanine-aminotransferase (ALT). It’s been also described the relation between a sharply decreased body mass index (BMI) and this kind of complications, but there are still to determine more predictors.
Objectives
Identifying clinical predictors of hepatic complications in AN.
Methods
We analysed data from 71 AN affected patients hospitalized at Bellvitge Hospital from January 2016 to October 2021. We used IBM SPSS Statistics 22 to do all the statistics in this work.
Results
The medium age of the sample was 27.66 years with 10.8 years of evolution of AN. The medium BMI was 13.88. 33.80% of them had some sort of hepatic enzymes elevation, two of them a several one. AST, ALT and ALP were significantly more elevated in those patients with lower BMI. GGT was significantly more elevated in patients with more years of disorder development. We didn’t identify correlation between any purgative method and hepatic alterations.
Conclusions
The elevation of ALT, AST and ALP seems to be related with the BMI of the patients, while the elevation of the GGT turns out to be related to the time of evolution of the eating disorder. Purgative methods don’t seem to be related to the development of hepatic alterations in AN.

Abstract
Image processing in cryogenic electron tomography (cryoET) is currently at a similar state as Single Particle Analysis (SPA) in cryogenic electron microscopy (cryoEM) was a few years ago. Its data processing workflows are far from being well defined and the user experience is still not smooth. Moreover, file formats of different software packages and their associated metadata are not standardized, mainly since different packages are developed by different groups, focusing on different steps of the data processing pipeline. The Scipion framework, originally developed for SPA (de la Rosa-Trevín et al., 2016), has a generic python workflow engine that gives it the versatility to be extended to other fields, as demonstrated for model building (Martínez et al., 2020). In this article, we provide an extension of Scipion based on a set of tomography plugins (referred to as ScipionTomo hereafter), with a similar purpose: to allow users to be focused on the data processing and analysis instead of having to deal with multiple software installation issues and the inconvenience of switching from one to another, converting metadata files, managing possible incompatibilities, scripting (writing a simple program in a language that the computer must convert to machine language each time the program is run), etcetera. Additionally, having all the software available in an integrated platform allows comparing the results of different algorithms trying to solve the same problem. In this way, the commonalities and differences between estimated parameters shed light on which results can be more trusted than others. ScipionTomo is developed by a collaborative multidisciplinary team composed of Scipion team engineers, structural biologists, and in some cases, the developers whose software packages have been integrated. It is open to anyone in the field willing to contribute to this project. The result is a framework extension that combines the acquired knowledge of Scipion developers in close collaboration with third-party developers, and the on-demand design of functionalities requested by beta testers applying this solution to actual biological problems.

Abstract
Introduction Neuroimaging findings have reported aberrant functional connectivity in brain regions involved reward system in individuals with anorexia nervosa (AN) altering hedonic processing over food. Likewise, endocannabinoids such as Anandamide (AEA) and 2-Arachidonoylglycerol (2-AG) have been involved in rewarding aspects of food intake. Objectives To identify nucleus accumbens (NAcc) functional connectivity with whole-brain comparing between individuals with AN and controls. Furthermore, in a sub-study, to explore the interaction between NAcc functional connectivity and peripheral AEA and 2-AG levels. Methods A total of 60 adult women (18 to 56 years of age) took part in the present study. Twenty-six individuals belonged to the AN group (BMI<18) and 34 to the HC group (BMI=18-24.99). All participants underwent functional magnetic resonance in resting-state, and blood samples were obtained in fasting. Results Negative functional connectivity was observed in the AN group compared with the control group between the NAcc and the cerebellum (pFWE<.001), between the NAcc and the insula (pFWE<.001), between the NAcc and the supramarginal gyrus (pFWE=.019), and between the NAcc and the postcentral gyrus (pFWE=.010). Analyses exploring the association between NAcc functional connectivity and peripheral endocannabinoids levels displayed altered NAcc-cerebellum functional connectivity was negatively associated with peripheral 2-AG levels in the AN group (r= -.553; p=.011). Conclusions Understanding the interaction between the reward system and peripheral endocannabinoids in patients with AN could contribute to better elucidate the pathophysiology of this disorder. Future studies will need to further investigate the clinical and therapeutic implications of these findings in patients with AN. Disclosure No significant relationships.

Abstract
Introduction COVID19 lockdown is having a significant impact on mental health, patients with eating disorders (ED) are particularly vulnerable. Objectives 1) To explore changes in eating and other psychological features due to confinement in patients with ED from various European and Asian countries; and 2) to assess differences related to diagnostic subtypes, age and geography. Methods The sample comprised 829 participants, diagnosed with an ED according to DSM-5 criteria from specialized ED units in Europe and Asia. Participants were assessed using the COVID19 Isolation Scale (CIES). Results On one hand, patients with Binge Eating Disorder experienced the highest impact on weight and ED symptoms due to confinement. Together with subjects diagnosed with Other Specified Feeding and Eating Disorders (OFSED), they also experienced a deterioration in general psychological state. On the other hand, there was less symptomatic impact on people with Bulimia Nervosa or Anorexia Nervosa and asian and younger individuals appeared to be more resilient in this situation. Conclusions The impact of COVID varied by cultural context and individual variation in age and form of illness. Services may need to target preventive measures and adapting therapeutic approaches for the most vulnerable patients. Disclosure No significant relationships.

Abstract
Introduction Anandamide (AEA) and 2-Arachidonoylglycerol (2-AG) play a pivotal role in food intake and reward aspects of feeding. Aberrant functioning in the endocannabinoid system has been observed in patients with eating disorders (EDs). This dysfunction may influence the incentive processes stimulating behaviors towards food acquisition or the hedonic evaluation of ingested food. Objectives The aims of this study are to compare fasting peripheral levels of AEA and 2-AG in ED patients, obese subjects (OB) and healthy controls (HCs), and to explore their association with clinical and anthropometric variables. Methods The sample included a total of 63 adult women. Peripheral blood samples were collected to investigate fasting levels of AEA and 2-AG in 31 ED patients: 22 Anorexia Nervosa (AN) and 9 Binge Eating Disorder (BED), compared to 21 OB and 11 HCs. Several clinical and anthropometric variables were also assessed. Results Comparing groups, significant differences in AEA levels were found (p=0.001). Specifically, individuals with AN exhibited lower AEA than OB (p<0.001) and BED (p=0.007), while OB showed higher AEA than HCs (p=0.015). 2-AG was positively correlated with hostility dimension in EDs and negatively associated with impulsive traits in OB. AEA showed a direct association with body dissatisfaction in AN, contrary to OB. Finally, in AN, AEA negatively correlated with the body mass index, while 2-AG was positively associated with the fat mass. Conclusions These results suggest an interaction between biological and clinical factors defining a vulnerability pathway that could help fitting personalized therapeutic approaches in each condition.

Abstract
PURPOSE Reentrant atrial tachycardias (ATs) use areas of slow conduction that can be visualized as fragmented electrograms. We aimed to test an ablation strategy based on the identification and ablation of spots with fragmented electrograms in reentrant ATs, using Rhythmia navigation system. METHODS All consecutive patients from June 2016 to June 2019 were included. The IntellaMap ORION Catheter was used to detect sites with fragmentation, arbitrarily defined as fragmented electrograms > 70 ms. Entrainment was used to check if these areas belonged to the AT circuit. Ablation targeted the longest fragmented electrogram within the circuit: focal ablation for microreentries and lines for macroreentries. Ablation success was defined from each AT as conversion to sinus rhythm or another AT. RESULTS Twenty-seven consecutive patients with 44 mappable ATs were included. All ATs showed sites with fragmented electrograms (104 sites; 2.4 sites per AT); 43/44 ATs had fragmented electrograms within the circuit, which were the target of ablation. Ablation success: 34/36 ATs (94%); success could not be assessed in 8 circuits, in 6 due to mechanical conversion to sinus rhythm at the target fragmented site. Fragmented electrograms within the AT circuits were longer than electrograms outside the circuits (110 ± 30 vs 90 ± 15 ms, p < 0.001). A fragmentation duration > 100 ms/ > 40% of the AT cycle length predicted to be a successful site for ablation with 72.3%/73.8% specificity, respectively. Sixty-two percent of the patients were free from atrial arrhythmias at 1 year. CONCLUSIONS Most ATs had detectable fragmented electrograms within the circuit, which could be the target of ablation with high efficacy.

Abstract
IntroductionThe Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5) introduced severity indices for Eating Disorders (ED).ObjectivesThis study assessed in a male ED sample the DSM-5 severity indices for Anorexia Nervosa (AN), Bulimia Nervosa (BN) and Binge Eating Disorder (BED) and compared them to an alternative transdiagnostic drive for thinness (DT) severity category and a combined DSM-5/DT severity categorizationMethods178 males with EDs were classified using: a.) a DT categorisation based on the EDI-2 DT subscale; b.) the DSM-5 severity categories for AN, BN and BED and c.) a combination of the DT and the DSM-5 severity categorisation. These severity classifications were then compared based on psychopathology and personality.ResultsFor the DSM-5 severity indices, the “mild” category was most prevalent for AN and BN, and the “moderate to extreme” group for BED. For the EDI-2 DT severity classification, the “mild” category was overrepresented in all subtypes. For the combined DSM-5/DT categorization, the “mild combined” severity group was the most prevalent for AN, while for BN and BED the “severe/extreme” combined group was most prevalent. Clinically significant findings were strongest for the DT categorization followed by the combined DSM-5/DT approach. Almost non-significant findings were revealed for the DSM-5 severity categories for all ED subtypes. These findings were most pronounced for AN and BN and almost non-existent for BED.ConclusionsOur findings provide support for DT as an alternative transdiagnostic severity category for EDs in males that may be more meaningful than the DSM-5 severity indices for AN and BN, but not BED.DisclosureNo significant relationships.

Abstract
Abstract
Background
Body composition is a parameter that is evaluated to predict the nutritional status of the population. This is assessed by bioelectric impedance analysis, which reports BMI, fat percentage, skeletal muscle mass, phase angle (AP), among others. The latter, in recent years has become important because it is a direct electrical measurement in the body, used for the clinical prognosis of diseases such as cancer, anorexy nervous, sarcopenia and chronic liver disease. AP is an index of vitality and integrality of the cell membrane and an indicator of muscle strength and endurance; likewise, it is inversely related to BMI, age and gender, normal values in healthy populations range between 5.5° to 9°, it is believed that physical activity and sport can also modify AP values. Therefore, the purpose of the study was to determine the relationship between body composition and AP in soccer players in Bogotá, Colombia.
Methods
Quantitative, cross-sectional, correlational approach. The sample was 84 soccer players (age: 18.67 + 2.9 years; height: 1.73 + 0.07 m; weight: 66.58 + 9.94 Kg), who were assessed using the Bioimpedance method through InBody 770®.
Results
The averages obtained were: AP 6.46°+0.58; muscle mass 32.25 + 5.06 Kg, percentage of fat mass 15.90 + 3.97. There was a direct relationship between AP, skeletal muscle mass and lean mass in the right, left arm, trunk and right leg (p < 0.01), while with the percentage of body fat mass of the right and left arm the relationship was inverse.
Conclusions
Body composition with high values of musculoskeletal mass and AP favor the functionality and development of strength, which in turn are protective factors for the presence of diseases such as sarcopenia.
Key messages
The Phase Angle is constituted as an easily accessible marker of nutritional health and morphofunctional profile in athletes. The Phase Angle and body composition as determinants of the profile in athletes.

Abstract
OBJECTIVE To demonstrate that the analysis of the atrioventricular, intraventricular, and interventricular asynchrony by point-of-care ultrasound (POCUS) could be an alternative tool for assessing complex arrhythmias in pediatric patients with congenital heart diseases, mainly when an epicardial register or electrophysiology study is not available. DESIGN Descriptive, retrospective case series study. SETTING The pediatric intensive care unit of a university-affiliated tertiary hospital in Spain. PATIENTS The authors included 12 patients with congenital heart disease younger than 18 years admitted to the authors' pediatric intensive care unit (PICU) from January 2018 to December 2019, with complex arrhythmias after surgery, managed by performing a bedside echocardiography when an electrophysiology test or epicardial auriculogram was unavailable. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The authors included a total of 14 complex arrhythmias in 12 postsurgical patients in whom a comprehensive transthoracic electrocardiogram was not conclusive. The presence of atrioventricular, intraventricular, or interventricular asynchrony was assessed in standard echo views by performing M-mode and Doppler mitral inflow analysis, checking the heart motion. The final POCUS diagnoses were atrial flutter (n = 5), postsurgical atrioventricular block (n = 4), asynchrony induced by pacemaker (n = 2), junctional ectopic tachycardia (n = 1), nodal rhythm plus ventricular extrasystole (n = 1), and supraventricular tachycardia (n = 1). In all patients, regardless of the type of arrhythmia, detecting motion asynchrony was crucial for making the correct diagnosis. Offline cardiologist analysis of the POCUS scans showed full agreement. CONCLUSIONS POCUS is a useful tool for initial diagnosis and management of complex arrhythmias in the PICU, mainly when epicardial auriculogram or electrophysiology studies are unavailable.

Abstract
BACKGROUND AND AIMS Protein-losing enteropathy (PLE) after Fontan surgery carries significant morbimortality. Its pathophysiology and association with other Fontan complications are poorly understood. Our aims were to examine whether Fontan-PLE is associated with greater liver damage and to assess the presence of systemic and intestinal inflammation. METHODS Fontan patients with PLE and Fontan controls without PLE matched for age and Fontan surgery procedure were included. Data were prospectively compiled on blood and stool tests, liver imaging, elastography, cardiac-MRI and cardiac catheterization. RESULTS Twenty-nine Fontan patients were enrolled (14 with PLE and 15 controls without PLE). Patients with PLE had more advanced liver disease estimated by non-invasive methods: blunt liver margins on ultrasonography (71.4% vs 26.7%, P = .027), greater median liver stiffness (25.4 vs 14.5 kPa, P = .003) and higher FIB-4 (P = .016). Portal hypertension-related signs were more common in patients with PLE including ascites (P = .035), larger spleen size (P = .005), oesophageal varices/splanchnic collateral shunts (P = .03), higher liver stiffness-spleen size-to-platelet ratio risk score (P < .001) and lower platelet count (P = .01). Systemic proinflammatory cytokines (TNF-α, interleukin-6), biomarkers of intestinal permeability (intestinal fatty-acid binding protein) and faecal calprotectin concentrations were also significantly increased in Fontan-PLE (P < .05). Faecal calprotectin directly correlated with alpha-1 antitrypsin clearance and inversely with cardiac index, total serum proteins and body mass index. CONCLUSION Fontan-PLE is associated with advanced liver disease and increased markers of systemic inflammation and intestinal permeability. Faecal calprotectin is elevated and correlates with Fontan-PLE severity. Liver assessment is mandatory in all Fontan patients, and especially in those with PLE.

Abstract
BACKGROUND AND AIMS Steroid-refractoriness is a common and unpredictable phenomenon in ulcerative colitis [UC], but there are no conclusive studies on the molecular functions involved. We aimed to assess the mechanism of action related to steroid failure by integrating transcriptomic data from UC patients, and updated molecular data on UC and glucocorticoids. METHODS MicroRNA [miRNA] and mRNA expression were evaluated by sequencing and microarrays, respectively, from rectal biopsies of patients with moderately-to-severe active UC, obtained before and on the third day of steroid treatment. The differential results were integrated into the mathematical models generated by a systems biology approach. RESULTS This computational approach identified 18 proteins that stand out either by being associated with the mechanism of action or by providing a means to classify the patients according to steroid response. Their biological functions have been linked to inflammation, glucocorticoid-induced transcription and angiogenesis. All the selected proteins except ANP32E [a chaperone which has been linked to the exchange of H2A.z histone and promotes glucocorticoid receptor-induced transcription] had previously been related to UC and/or glucocorticoid-induced biological actions. Western blot and immunofluorescence assays confirmed the implication of this chaperone in steroid failure in patients with active UC. CONCLUSIONS A systems biology approach allowed us to identify a comprehensive mechanism of action of steroid-refractoriness, highlighting the key role of steroid-induced transcription and the potential implication of ANP32E in this phenomenon.

Abstract
Previously we have demonstrated that the GJ protein connexin 30.2 (Cx30.2) is expressed in pancreatic beta cells and endothelial cells (ECs) of the islet. In the present study, we address whether Cx30.2 is expressed in the exocrine pancreas, including its vascular system. For this, adult mouse pancreatic sections were double labeled with specific antibodies against Cx30.2 and CD31, an endothelial cell marker, or with anti-α-actin smooth muscle, a smooth muscle cell (SMC) marker or anti-mucin-1, a marker of epithelial ductal cells, using immunofluorescence (IF) studies. Cx30.2-IF hot spots were found at junctional membranes of exocrine ECs and SMCs of blood vessels. Furthermore, Cx30.2 was localized in mucin-1 positive cells or epithelial ductal cells. Using immunohistochemistry (IHC) studies, it was found that in vessels and ducts of different diameters, Cx30.2 was also expressed in these cell types. In addition, it was found that Cx30.2 is already expressed in these cell types in pancreatic sections of 3, 14 and 21 days postpartum. Moreover, this cell specific pattern of expression was also found in the adult rat, hamster and guinea pig pancreas. Expression of Cx30.2 mRNA and protein in the pancreas of all these species was confirmed by RT-PCR and Western blot studies. Overall, our results suggest that intercellular coupling mediated by Cx30.2 intercellular channels may synchronize the functional activity of ECs and SMCs of vascular cells, as well as of epithelial ductal cells after birth.

Abstract
Actions taken to prevent or reduce coastal erosion often do not have the desired effect, leading to major problems instead of solving the original one. This research focuses on why a nourished beach- with borrowed sand and 0.05% of particles <0.063 mm- causes the presence of suspended particles that are observed by beach users as turbidity. This means that the colour of the water was not its characteristic blue, even with calm wave conditions. This research involved a shoreline evolution analysis and a sedimentological study of the sand from 1977 to 2017. The results show that the turbidity episodes that occurred after the beach fill of May 2017 do not coincide with major storms that affected the beach. Furthermore, prior to this beach nourishment, even after the most important storms turbidity was not so pronounced. However, when the pre-nourishment and post-nourishment sediment are compared and analysed in detail, by studying the microstructure and morphology of the sand particles, their composition and morphology were observed to be completely different. These differences are also reflected in the accelerated particle weathering test, with the post-nourishment particles showing greater dissolution of carbonates. From its mineralogy, the post-nourishment material presents a smaller proportion of quartz in its composition and a significant amount of particles (9.6%) formed by clusters of Calcium and Silicon. The separation of this mineralogical composition produced by waves explains the formation of particles measuring <0.063 mm, a fact that has also been confirmed by the accelerated particle weathering test. This is, therefore, the cause of turbidity in the swash zone of the beach.

Abstract
CR-39 nuclear track material is frequently used for the detection of protons accelerated in laser-plasma interactions. The measurement of track densities allows for determination of particle angular distributions, and information on the kinetic energy can be obtained by the use of passive absorbers. We present a precise method of measuring spectral distributions of laser-accelerated protons in a single etching and analysis process. We make use of a one-to-one relation between proton energy and track size and present a precise calibration based on monoenergetic particle beams. While this relation is limited to proton energies below 1 MeV, we show that the range of spectral measurements can be significantly extended by simultaneous use of absorbers of suitable thicknesses. Examples from laser-plasma interactions are presented, and quantitative results on proton energies and particle numbers are compared to those obtained from a time-of-flight detector. The spectrum end points of continuous energy distributions have been determined with both detector types and coincide within 50-100 keV.

Abstract
Infections due to multidrug-resistant bacteria (MDR) are currently a clinical challenge, mainly in elderly patients. The antimicrobial spectrum, safety and efficacy of ceftolozane/tazobactam (C/T) make it an attractive option for the treatment of MDR bacterial infections beyond the indications approved to date. Here we report our experience with C/T in four cases of osteomyelitis and three cases of skin and soft-tissue infections due to extensively-drug-resistant Pseudomonas aeruginosa.

Abstract
Transbronchial biopsy using forceps (TBB) is the first diagnostic technique performed on patients with interstitial lung disease (ILD). However, the small size of the samples and the presence of artefacts in the tissue obtained make the yield variable. Our objectives were 1) to attempt to reproduce transbronchial cryobiopsy under the same conditions with which we performed conventional TBB, that is, in the bronchoscopy unit without intubating the patient and without fluoroscopy or general anaesthesia; 2) to describe the method used for its execution; and 3) to analyse the diagnostic yield and its complications. We carried out a prospective study that included 106 patients with clinical and radiological features suggestive of ILD who underwent cryo-transbronchial lung biopsy (cryo-TBB) under moderate sedation without endotracheal intubation, general anaesthesia or use of fluoroscopy. We performed the procedure using two flexible bronchoscopes connected to two video processors, which we alternated until obtaining the number of desired samples. A definitive diagnosis was obtained in 91 patients (86%). As for complications, there were five pneumothoraces (4.7%) and in no case was there severe haemorrhage or exacerbation of the underlying interstitial disease. Cryo-TBB following our method is a minimally invasive, rapid, safe and economic technique that can be performed in a bronchoscopy suite under moderate sedation without the need for intubating the patient or using fluoroscopy and without requiring general anaesthesia.

Abstract
BACKGROUND Compulsive buying behavior (CBB) is receiving increasing consideration in both consumer and psychiatric-epidemiological research, yet empirical evidence on treatment interventions is scarce and mostly from small homogeneous clinical samples. OBJECTIVES To estimate the short-term effectiveness of a standardized, individual cognitive behavioral therapy intervention (CBT) in a sample of n=97 treatment-seeking patients diagnosed with CBB, and to identify the most relevant predictors of therapy outcome. METHOD The intervention consisted of 12 individual CBT weekly sessions, lasting approximately 45minutes each. Data on patients' personality traits, psychopathology, sociodemographic factors, and compulsive buying behavior were used in our analysis. RESULTS The risk (cumulative incidence) of poor adherence to the CBT program was 27.8%. The presence of relapses during the CBT program was 47.4% and the dropout rate was 46.4%. Significant predictors of poor therapy adherence were being male, high levels of depression and obsessive-compulsive symptoms, low anxiety levels, high persistence, high harm avoidance and low self-transcendence. CONCLUSION Cognitive behavioral models show promise in treating CBB, however future interventions for CBB should be designed via a multidimensional approach in which patients' sex, comorbid symptom levels and the personality-trait profiles play a central role.

Abstract
One of the main problems that coasts around the world present, is the regression and erosion of beaches. However, the factors involved in these processes are unclear. In this study, the influence of sediment erosion on beach regression has been analysed. In order to do that, a three-step investigation has been carried out. Firstly, coastline variations of four Spanish beaches have been analysed. Secondly, a study on sediment position along the beach profile has been developed. Finally, the process that beach sediments undergo along the surf zone when they are hit by the incident waves has been simulated by an accelerated particle weathering test. Samples of sand and shells were subjected to this accelerated particle weathering test. Results were supplemented with those from carbonate content test, XRD, SEM and granulometric analysis. Results shows a cross-shore classification of sediments along the beach profile in which finer particles move beyond offshore limit. Besides, it was observed that sediment erosion process is divided into three sages: i) particles wear due to crashes ii) dissolution of the carbonate fraction, and iii) breakage and separation of mineral and carbonate parts of particles. All these processes lead to a reduction of particle size. The mechanism responsible of beach erosion would consist of multiples and continuous particle location exchanges along the beach profile as a consequence of grain-size decrease due to erosion.

Abstract
The expression of CD64 in neutrophils (nCD64) has shown utility in the diagnosis of sepsis. The aim of this study was to assess the usefulness of nCD64 expression to identify patients with community-acquired pneumonia (CAP) at risk of a poor outcome. A prospective study of nCD64 expression (determined by flow cytometry) in patients with CAP was performed. The sensitivity/specificity of nCD64 in predicting poor outcome [defined as intensive care unit (ICU) admission and/or clinical deterioration after arrival at the emergency department] was calculated. Eighty-three adults with CAP were included; 14.5 % had septic shock, 19.3 % required ICU admission, and 10.8 % presented clinical deterioration after admission. The mean of the median fluorescence intensity (MFI) of nCD64 expression was 1140 (±1097). Patients with nCD64 expression ≥2700 MFI had more clinical deterioration (36.4 vs. 7.2 %, p = 0.015) and more ICU admission (45.5 vs. 14.5 %, p = 0.028). To identify clinical deterioration and ICU admission, nCD64 expression showed a sensitivity of 44.4 and 33.3 % and a specificity of 90.1 and 90.8 %, respectively. The addition of nCD64 expression to the Pneumonia Severity Index and CURB-65 severity scores did not improve the accuracy of predicting these outcomes. Although nCD64 expression is associated with an increased risk of ICU admission or clinical deterioration after admission, its accuracy in predicting these poor outcomes is modest and does not significantly improve the predictive ability of the PSI and CURB-65 severity scores.

Abstract
INTRODUCTION Ultrasound guidance for vascular cannulation seems safer and more effective than an anatomical landmark approach, though it has not gained widespread support partly due to workflow interference of wired probes. A wireless ultrasound transducer (WUST) may overcome this issue. We report the effectiveness, time consumption, and safety of the first-in-human experience in axillary vein cannulation guided with a novel WUST for the implantation of cardiovascular implantable electric devices (CIEDs). METHODS AND RESULTS After a one-month training period, we routinely performed WUST-guided puncture to all first implants, prospectively registering data from the first 50 patients. We analyzed the time needed for preparing the WUST and for achieving each vein cannulation, and the rate of unsuccessful or accidental arterial punctures and complications. WUST-guided axillary vein access was successful in 49 out of 50 patients, totaling 86 cannulated veins. Median WUST preparation time was 55 [44-62] seconds and median time needed for each venous cannulation was 56 [36-71] seconds. A total of 84.9% of the veins were cannulated at the first attempt. There were 7 unsuccessful puncture attempts and 1 accidental arterial puncture. No pneumothorax, hemothorax, or nervous injury occurred in the 49 successfully cannulated patients. The unsuccessful one (distal subclavian occlusion) developed a minor local subcutaneous emphysema with no confirmed radiologic pneumothorax, not requiring intervention. During a follow-up of 2.5 ± 1.1 months, a patient developed a pocket infection, with no other significant complications. CONCLUSION Ultrasound-guided axillary vein cannulation using a wireless transducer for the implantation of CIEDs is a feasible, fast, and safe method.

Abstract
OBJECTIVE Elevated physical activity has been observed in some patients with anorexia nervosa (AN) despite their emaciated condition. However, its effects on treatment outcome remain unclear. This study aimed to examine objectively measured physical activity in this clinical population and how it might be related to a partial hospitalization therapy response, after considering potential confounders. METHOD The sample comprised 88 AN patients consecutively enrolled in a day hospital treatment program, and 116 healthy-weight controls. All participants were female and a baseline assessment took place using an accelerometer (Actiwatch AW7) to measure physical activity, the Eating Disorders Inventory-2 and the Depression subscale of the Symptom Checklist-Revised. Outcome was evaluated upon the termination of the treatment program by expert clinicians. RESULTS Although AN patients and controls did not differ in the average time spent in moderate-to-vigorous physical activity (MVPA) (P=.21), nor daytime physical activity (P=.34), fewer AN patients presented a high physical activity profile compared to the controls (37% vs. 61%, respectively; P=.014). Both lower levels of MVPA and greater eating disorder severity had a direct effect on a poor treatment outcome. Depression symptoms in the patients were associated with lower MVPA, as well as with an older age, a shorter duration of the disorder and greater eating disorder psychopathology. CONCLUSIONS There is a notable variation in the physical activity profile of AN patients, characterized by either low or very high patterns. Physical activity is a highly relevant issue in AN that must be taken into account during the treatment process.

Abstract
Intensive scientific research devoted in the recent years to understand the molecular mechanisms or neurodegeneration in spinocerebellar ataxias (SCAs) are identifying new pathways and targets providing new insights and a better understanding of the molecular pathogenesis in these diseases. In this consensus manuscript, the authors discuss their current views on the identified molecular processes causing or modulating the neurodegenerative phenotype in spinocerebellar ataxias with the common opinion of translating the new knowledge acquired into candidate targets for therapy. The following topics are discussed: transcription dysregulation, protein aggregation, autophagy, ion channels, the role of mitochondria, RNA toxicity, modulators of neurodegeneration and current therapeutic approaches. Overall point of consensus includes the common vision of neurodegeneration in SCAs as a multifactorial, progressive and reversible process, at least in early stages. Specific points of consensus include the role of the dysregulation of protein folding, transcription, bioenergetics, calcium handling and eventual cell death with apoptotic features of neurons during SCA disease progression. Unresolved questions include how the dysregulation of these pathways triggers the onset of symptoms and mediates disease progression since this understanding may allow effective treatments of SCAs within the window of reversibility to prevent early neuronal damage. Common opinions also include the need for clinical detection of early neuronal dysfunction, for more basic research to decipher the early neurodegenerative process in SCAs in order to give rise to new concepts for treatment strategies and for the translation of the results to preclinical studies and, thereafter, in clinical practice.

Abstract
OBJECTIVE To assess glycemic variability, oxidative stress and their relationship in children and adolescents with type 1 diabetes (T1DM) attending a summer camp. PATIENTS AND METHOD Cross-sectional study that included 54 children and adolescents with T1DM aged 7-16, attending a 7 day summer camp. Sociodemographic information, clinical data, and blood glucose values measured using an Accu-Chek Nano® glucose meter were recorded. Glucose variability markers (standard deviation [SD], low blood glucose index [LBGI], high blood glucose index [HBGI], mean amplitude of glycemic excursions [MAGE] and mean of daily differences [MODD]) were calculated. Oxidative stress was assessed by the measurement of 8-iso-prostaglandin F2 alpha (PGF2α) in a 24-hour urine sample collected at the end of the camp in 14 children. RESULTS The Median SD, MAGE and MODD indexes were in the high range (61, 131 and 58 mg/dl, respectively), LBGI in the moderate range (3.3), and HBGI in the low range (4.5). The mean HbA1c was 7.6% and the median urinary excretion rate of 8-iso-PGF2α was 864.39 pg/mg creatinine. The Spearman correlation coefficients between markers of glycemic variability (SD, HBGI, MAGE, MODD) were significant. Non-significant correlations were found between markers of glycemic variability and urinary 8-iso-PGF2α. CONCLUSIONS High glycemic variability was observed in children and adolescents attending a summer camp. However, no correlations were found between markers of glycemic variability and oxidative stress measured by urinary 8-iso-PGF2α. Further studies are needed to address the relationship between oxidative stress and glycemic variability in children with T1DM.

Abstract
OBJECTIVE The literature on later age of onset (LAO) in women with eating disorders is scarce. We compared the severity of eating disorders, eating disorder subtype, and personality profiles in a clinical sample of consecutively assessed women with eating disorders with later age of onset (LAO, > = 25 years) to women with typical age of onset (TAO, <25 years). METHOD All eating disorder patients met the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition (DSM-IV) criteria and were admitted to the Eating Disorder Unit of the University Hospital of Bellvitge in Barcelona, Spain. Ninety-six patients were classified as LAO and 759 as TAO. ASSESSMENT Measures included the Eating Attitude Test-40 (EAT-40), Eating Disorders Inventory-2 (EDI-2), Bulimic Investigatory Test Edinburgh (BITE), Symptom Checklist Revised (SCL-90-R), and the Temperament and Character Inventory-Revised (TCI-R), as well as other clinical and psychopathological indices. RESULTS LAO individuals reported significantly fewer weekly vomiting episodes, fewer self-harming behaviours, less drug abuse, and lower scores on the BITE symptoms, the EDI-2 drive for thinness, and the TCI-R harm avoidance scales than TAO individuals. Conversely, the LAO group reported more current and premorbid obesity than the TAO group. CONCLUSION LAO eating disorder patients in this sample presented with milder symptomatology and less extreme personality traits. Premorbid obesity may be more relevant to LAO than TAO eating disorders and should be routinely assessed and considered when planning treatment.

Abstract
AIMS To perform an international trial to derive alert and action levels for the use of quantitative PCR (qPCR) in the monitoring of Legionella to determine the effectiveness of control measures against legionellae. METHODS AND RESULTS Laboratories (7) participated from six countries. Legionellae were determined by culture and qPCR methods with comparable detection limits. Systems were monitored over ≥10 weeks. For cooling towers (232 samples), there was a significant difference between the log mean difference between qPCR (GU l(-1) ) and culture (CFU l(-1) ) for Legionella pneumophila (0·71) and for Legionella spp. (2·03). In hot and cold water (506 samples), the differences were less, 0·62 for Leg. pneumophila and 1·05 for Legionella spp. Results for individual systems depended on the nature of the system and its treatment. In cooling towers, Legionella spp. GU l(-1) always exceeded CFU l(-1) , and usually Legionella spp. were detected by qPCR when absent by culture. The pattern of results by qPCR for Leg. pneumophila followed the culture trend. In hot and cold water, culture and qPCR gave similar results, particularly for Leg. pneumophila. There were some marked exceptions with temperatures ≥50°C, or in the presence of supplementary biocides. Action and alert levels for qPCR were derived that gave results comparable to the application of the European Guidelines based on culture. Algorithms are proposed for the use of qPCR for routine monitoring. CONCLUSIONS Action and alert levels for qPCR can be adjusted to ensure public health is protected with the benefit that remedial actions can be validated earlier with only a small increase in the frequency of action being required. SIGNIFICANCE AND IMPACT OF THE STUDY This study confirms it is possible to derive guidelines on the use of qPCR for monitoring the control of legionellae with consequent improvement to response and public health protection.

Abstract
This paper describes an evaluation framework that allows a standardized and objective quantitative comparison of carotid artery lumen segmentation and stenosis grading algorithms. We describe the data repository comprising 56 multi-center, multi-vendor CTA datasets, their acquisition, the creation of the reference standard and the evaluation measures. This framework has been introduced at the MICCAI 2009 workshop 3D Segmentation in the Clinic: A Grand Challenge III, and we compare the results of eight teams that participated. These results show that automated segmentation of the vessel lumen is possible with a precision that is comparable to manual annotation. The framework is open for new submissions through the website http://cls2009.bigr.nl.

Abstract
BACKGROUND It is unclear whether premenstrual asthma is associated with premenstrual syndrome. The objective of this study is to compare premenstrual symptoms among asthmatic women according to whether they have premenstrual asthma or not. METHODS A questionnaire on respiratory symptoms during a single menstrual cycle was developed for asthmatics of fertile age, together with another on symptoms related to premenstrual syndrome. These included dysphoric-psychiatric symptoms (anxiety, depression, fatigue, irritability, and mood swings), edematous symptoms (abdominal and mammary tension, swelling, acne, and migraine), and other symptoms (leg pains, nausea, sweating, vomiting, and tiredness). Morning and evening peak flow scores were collected to evaluate lung function. Premenstrual asthma was determined to be a ≥ 20% objective exacerbation in the premenstrual phase over the preovulatory phase in terms of both respiratory symptoms and/or peak flow. The intensity of the change in symptoms was evaluated according to the effect size. RESULTS The study examined 103 patients of fertile age, 46 of whom (44.7%) presented with premenstrual asthma. Practically all of the monitored symptoms increased in the premenstrual phase with respect to the preovulatory phase. This increase was greater in women with premenstrual asthma, especially for abdominal tension (effect size .88 against .33; p = .009) and mammary tension (.95 against .49; p = .018). CONCLUSIONS A clear link was found between premenstrual asthma and the premenstrual exacerbation of dysphoric symptoms, and certain edematous symptoms such as abdominal and mammary tension as well as a swelling sensation.

Abstract
We describe a case of encapsulated papillary carcinoma (EPC), apocrine variant in a 50-year-old woman. The patient presented a cystic lesion in her right breast, measuring 8 cm in diameter, containing three solid papillary nodules. A fine-needle aspiration showed isolated apocrine cells containing round nuclei, irregular nuclear membranes, fine chromatin, and prominent macronucleoli. The lesion was excised and showed a pure papillary apocrine carcinoma, which stained diffusely with GCDFP-15 and androgen receptors. The lesion was totally devoid of myoepithelial cells (smooth muscle actyn, p63, calponin, and collagen IV stains were negative). With MIB1 the proliferative activity was 10%. To the best of our knowledge, this is the first report of EPC apocrine variant with cytologic and immunohistochemical study. This lesion must be included in the list of apocrine lesions of the breast.
