Abstract
Atrial biophysical simulations have the potential to enhance outcomes by enabling the simulation of pharmacological and ablative strategies. However, the high computational times associated with such simulations render them unsuitable for diagnostic purposes. To address this challenge, discrete models such as cellular automata (CA) have been developed, which consider a finite number of states, thus significantly reducing computational times. Yet, there is a pressing need to determine whether CA can replicate pathological simulations with accuracy. The analysis of simulations under different degrees of electrical remodeling shows an expected increase of Action Potential Duration (APD) with the previous Diastolic Interval (DI) interval, indicating short-term memory of atrial cardiomyocytes: shorter APD0 provoked shorter APD+1, and previous DI has a similar effect on APD+1. Independent prediction using both APD0 and DI was found to provide a far better estimation of APD+1 values, compared to relying on DI alone (p<<0.01). Finally, the CA models were able to replicate reentrant patterns and cycle lengths of different states of atrial remodeling with a high degree of accuracy when compared to biophysical simulations. Overall, the use of atrial CA with short-term memory allows accurate reproduction of arrhythmic behavior in pathological tissue within a clinically relevant timeframe.Clinical Relevance- Discrete electrophysiological models simulate pathological self-sustained arrhythmias in diagnostic times.

Abstract
Patients that have suffered a myocardial infarction are at high risk of developing ventricular tachycardia. Patient stratification is often determined by characterization of the underlying myocardial substrate by cardiac imaging methods. In this study, we show that computer modeling of cardiac electrophysiology based on personalized fast 3D simulations can help to assess patient risk to arrhythmia. We perform a large simulation study on 21 patient digital twins and reproduce successfully the clinical outcomes. In addition, we provide the sites which are prone to sustain ventricular tachycardias, i.e, onset sites around the scar region, and validate if they colocalize with exit sites from slow conduction channels.Clinical relevance- Fast electrophysiological simulations can provide advanced patient stratification indices and predict arrhythmic susceptibility to suffer from ventricular tachycardia in patients that have suffered a myocardial infarction.

Abstract
Most mitigation strategies to reduce enteric methane (CH4) production in the rumen induce an excess of rumen dihydrogen (H2) that is expelled and consequently not redirected to the synthesis of metabolites that can be utilised by the ruminant. We hypothesised that phenolic compounds can be potential H2 acceptors when added to the diet, as they can be degraded to compounds that may be beneficial for the animal, using part of the H2 available when ruminal methanogenesis is inhibited. We performed four in vitro incubation experiments using rumen inoculum from Murciano-Granadina adult goats: Experiment 1 examined the inhibitory potential of Asparagopsis taxiformis (AT) at different concentrations (0, 1, 2, 3, 4 and 5% of the substrate on a DM basis) in 24 h incubations; Experiment 2 investigated the effect of a wide range of phenolic compounds (phenol, catechol, resorcinol, hydroquinone, pyrogallol, phloroglucinol, gallic acid and formic acid) at different doses (0, 2, 4, and 6 mM) on rumen fermentation for 24 h; Experiment 3 evaluated the combined effect of each phenolic compound at 6 mM with AT at 2% DM in sequential batch cultures for 5 days; and Experiment 4 examined the dose-response effect of phloroglucinol at different concentrations (0, 6, 16, 26 and 36 mM) combined with AT in sequential batch cultures for 5 days. Results from Experiment 1 confirmed that AT at 2% DM substantially inhibited CH4 production while significantly increasing H2 accumulation and decreasing the acetate:propionate ratio. Results from Experiment 2 showed that phenolic compounds did not negatively affect rumen fermentation at any dose. In Experiment 3, each phenolic compound at 6 mM combined with AT at 2% DM inhibited CH4 production. Phloroglucinol numerically decreased H2 accumulation and significantly increased total gas production (TGP), volatile fatty acid (VFA) production and the acetate:propionate ratio. In Experiment 4, phloroglucinol at increasing doses supplemented with AT at 2% DM significantly decreased H2 accumulation and the abundances of archaea, protozoa and fungi abundances, and increased TGP, total VFA production and the acetate:propionate ratio in a dose-dependent way. In conclusion, combined treatment with AT and phloroglucinol was successful to mitigate CH4 production while preventing the accumulation of H2, leading to an increase in acetate and total VFA production and therefore an improvement in rumen fermentation in goats.

Abstract
Some antimethanogenic feed additives for ruminants promote rumen dihydrogen (H2) accumulation potentially affecting the optimal fermentation of diets. We hypothesised that combining an H2 acceptor with a methanogenesis inhibitor can decrease rumen H2 build-up and improve the production of metabolites that can be useful for the host ruminant. We performed three in vitro incubation experiments using rumen fluid from lactating Holstein cows: Experiment 1 examined the effect of phenolic compounds (phenol, catechol, resorcinol, hydroquinone, pyrogallol, phloroglucinol, and gallic acid) at 0, 2, 4, and 6 mM on ruminal fermentation for 24 h; Experiment 2 examined the combined effect of each phenolic compound from Experiment 1 at 6 mM with two different methanogenesis inhibitors (Asparagopsis taxiformis or 2-bromoethanesulfonate (BES)) for 24 h incubation; Experiment 3 examined the effect of a selected phenolic compound, phloroglucinol, with or without BES over a longer term using sequential incubations for seven days. Results from Experiment 1 showed that phenolic compounds, independently of the dose, did not negatively affect rumen fermentation, whereas results from Experiment 2 showed that phenolic compounds did not decrease H2 accumulation or modify CH4 production when methanogenesis was decreased by up to 75% by inhibitors. In Experiment 3, after three sequential incubations, phloroglucinol combined with BES decreased H2 accumulation by 72% and further inhibited CH4 production, compared to BES alone. Interestingly, supplementation with phloroglucinol (alone or in combination with the CH4 inhibitor) decreased CH4 production by 99% and the abundance of methanogenic archaea, with just a nominal increase in H2 accumulation. Supplementation of phloroglucinol also increased total volatile fatty acid (VFA), acetate, butyrate, and total gas production, and decreased ammonia concentration. This study indicates that some phenolic compounds, particularly phloroglucinol, which are naturally found in plants, could improve VFA production, decrease H2 accumulation and synergistically decrease CH4 production in the presence of antimethanogenic compounds.

Abstract
Current evidence and recent publications have led to the recognition that aerosol-borne transmission of COVID-19 is possible in indoor areas such as educational centers. A crucial measure to reduce the risk of infection in high occupancy indoors is ventilation. In this global pandemic context of SARS-CoV-2 virus infection, a study has been carried out with the main objective of analyzing the effects of natural ventilation conditions through windows on indoor air quality and thermal comfort during on-site examinations in higher education centers during the winter season, as this implies situations of unusual occupation and the impossibility in many cases of taking breaks or leaving classrooms, as well as the existence of unfavorable outdoor weather conditions in terms of low temperatures. For this purpose, in situ measurements of the environmental variables were taken during different evaluation tests. As the main results of the study, ventilation conditions were generally adequate in all the tests carried out, regardless of the ventilation strategy used, with average CO2 concentration levels of between 450 and 670 ppm. The maximum CO2 concentration value recorded in one of the tests was 808 ppm. On this basis, the limit for category IDA 2 buildings, corresponding to educational establishments, was not exceeded in any case. However, these measures affected the thermal comfort of the occupants, especially when the outside temperature was below 6 °C, with a dissatisfaction rate of between 25 and 72%. Examinations carried out with outside temperatures above 12 °C were conducted in acceptable comfort conditions regardless of outside air supply and classroom occupancy. In these cases, the dissatisfaction rate was less than 10%. The results obtained have made it possible to establish strategies for ventilation in the implementation of future exams, depending on the climatic conditions outside.

Abstract
Cancer vaccines (CVs) represent a long-sought therapeutic and prophylactic immunotherapy strategy to obtain antigen (Ag)-specific T-cell responses and potentially achieve long-term clinical benefit. However, historically, most CV clinical trials have resulted in disappointing outcomes, despite promising signs of immunogenicity across most formulations. In the past decade, technological advances regarding vaccine delivery platforms, tools for immunogenomic profiling, and Ag/epitope selection have occurred. Consequently, the ability of CVs to induce tumor-specific and, in some cases, remarkable clinical responses have been observed in early-phase clinical trials. It is notable that the record-breaking speed of vaccine development in response to the coronavirus disease-2019 pandemic mainly relied on manufacturing infrastructures and technological platforms already developed for CVs. In turn, research, clinical data, and infrastructures put in place for the severe acute respiratory syndrome coronavirus 2 pandemic can further speed CV development processes. This review outlines the main technological advancements as well as major issues to tackle in the development of CVs. Possible applications for unmet clinical needs will be described, putting into perspective the future of cancer vaccinology.

Abstract
During ischemia/reperfusion (I/R), cardiomyocytes activate pathways that regulate cell survival and death and release factors that modulate fibroblast-to-myofibroblast differentiation. The mechanisms underlying these effects are not fully understood. Polycystin-1 (PC1) is a mechanosensor crucial for cardiac function. This work aims to assess the role of PC1 in cardiomyocyte survival, its role in profibrotic factor expression in cardiomyocytes, and its paracrine effects on I/R-induced cardiac fibroblast function. In vivo and ex vivo I/R and simulated in vitro I/R (sI/R) were induced in wild-type and PC1-knockout (PC1 KO) mice and PC1-knockdown (siPC1) neonatal rat ventricular myocytes (NRVM), respectively. Neonatal rat cardiac fibroblasts (NRCF) were stimulated with conditioned medium (CM) derived from NRVM or siPC1-NRVM supernatant after reperfusion and fibroblast-to-myofibroblast differentiation evaluated. Infarcts were larger in PC1-KO mice subjected to in vivo and ex vivo I/R, and necrosis rates were higher in siPC1-NRVM than control after sI/R. PC1 activated the pro-survival AKT protein during sI/R and induced PC1-AKT-pathway-dependent CTGF expression. Furthermore, conditioned media from sI/R-NRVM induced PC1-dependent fibroblast-to-myofibroblast differentiation in NRCF. This novel evidence shows that PC1 mitigates cardiac damage during I/R, likely through AKT activation, and regulates CTGF expression in cardiomyocytes via AKT. Moreover, PC1-NRVM regulates fibroblast-to-myofibroblast differentiation during sI/R. PC1, therefore, may emerge as a new key regulator of I/R injury-induced cardiac remodeling.

Abstract
Cannabis sativa is a source of food, fiber and specialized metabolites such as cannabinoids, with psychoactive and pharmacological effects. Due to its expanding and increasingly-accepted use in medicine, cannabis cultivation is acquiring more importance and less social stigma. Humans initiated different domestication episodes whose later spread gave rise to a plethora of landrace cultivars. At present, breeders cross germplasms from different gene pools depending on their specific use. The fiber (hemp) and drug (marijuana) types of C. sativa differ in their cannabinoid chemical composition phenotype (chemotype) and also in the accumulation of terpenoid compounds that constitute a strain's particular flavor and scent. Cannabinoids are isoprenylated polyketides among which cannabidiolic acid (CBDA) and (-)-trans-Δ⁹-tetrahydrocannabinol acid (THCA) have been well-documented for their many effects on humans. Here, we review the most studied specialized metabolic pathways in C. sativa, showing how terpenes and cannabinoids share both part of the isoprenoid pathway and the same biosynthetic compartmentalization (i.e. glandular trichomes of leaves and flowers). We enlist the several studies that have deciphered these pathways in this species including physical and genetic maps, QTL analyses and localization and enzymatic studies of cannabinoid and terpene synthases. In addition, new comparative modeling of cannabinoid synthases and phylogenetic trees are presented. We describe the genome sequencing initiatives of several accessions with the concomitant generation of next-generation genome maps and transcriptomic data. Very recently, proteomic characterizations and systems biology approaches such as those applying network theory or the integration of multi-omics data have increased the knowledge on gene function, enzyme diversity and metabolite content in C. sativa. In this revision we drift through the history, present and future of cannabis research and on how second- and third-generation sequencing technologies are bringing light to the field of cannabis specialized metabolism. We also discuss different biotechnological approaches for producing cannabinoids in engineered microorganisms.

Abstract
Leishmaniasis is a zoonotic disease caused by intracellular protozoa of the Leishmania genus that are spread and transmitted by sandflies. Natural infection and clinical disease in domestic cats and dogs appear to be rare or perhaps largely under-reported in endemic areas. However, previous reports on infected domestic animals usually implicate the same Leishmania species that affect humans in tropical and subtropical areas of the world suggesting a potential role for zoonotic transmission. In the present study we assessed a representative sample of cats and dogs from endemic urban / suburban areas of Lara state in central western Venezuela. In both dogs and cats, cutaneous disease exhibits a spectrum of manifestations that range from single papules or nodules, which may evolve into ulcerative, plaque-like or scaly lesions. Cytochrome b (cyt b) PCR gene sequence analysis revealed L. mexicana as the causative agent in all cases, including two human cases proceeding from the same study area at the same time the study was carried out. In order to improve our understanding on feline/canine infection with Leishmania mexicana, and address potential zoonotic concerns it is necessary to characterize its enzootic reservoirs and vectors as well as the possible anthropophilic players linking to the peridomestic and domestic cycles.

Abstract
Abstract
Medullary breast carcinoma (MBC) is a rare subtype of triple negative breast cancer (TNBC)with specific genomic features within the spectrum of basal-like carcinoma. The frequent association between BRCA constitutive mutation and MBC phenotype has been reported previously. In this study including 19 MBC and 36 non-MMB basal-like carcinoma (BLC), we refine the genomic and transcriptomic knowledge about this entity. Using pan genomic Affymetrix genome-wide human SNP6.0 array, we show that i/ MBC harbour more copy number alterations and losses of heterozygocity than BLC and that ii/ the high frequency of BRCAness genomic trait among MBC. Unsupervised and supervised analysis of GeneChip Uman Genome U133 Plus 2.0 Array transcriptomic generated data confirmed that MBC clearly differ from BLC in terms of gene expression level, with 92 genes overexpressed and 154 genes underexpressed in MBC over BLC. Immune response and inflammatory response are the most differentially represented pathways in MBC over BLC. Pro apoptotic gene BCLG is by far the more overexpressed gene in MBC. A validation study conducted with RT-QPCR among 526 breast tumors form all molecular subtype confirmed the specificity of BCLG overexpression in MBC, which was confirmed at protein level using immunohistochemisytry. Moreover, we show that a vast majority of MBC belong o the immunomodulatory TNBC subtype according to Lehman et al. Finally, we confirm the better prognosis of MBC toward BLC. Our observations epitomize the importance of developing DNA repair targeting drugs and immunotherapy based trials in order to improve the outcome of such a specific entity.

Abstract
Long synthetic peptides and CpG-containing oligodeoxynucleotides are promising components for cancer vaccines. In this phase I trial, 19 patients received a mean of 8 (range 1-12) monthly vaccines s.c. composed of the long synthetic NY-ESO-179-108 peptide and CpG-B (PF-3512676), emulsified in Montanide ISA-51. In 18/18 evaluable patients, vaccination induced antigen-specific CD8+ and CD4+ T-cell and antibody responses, starting early after initiation of immunotherapy and lasting at least one year. The T-cells responded antigen-specifically, with strong secretion of IFNγ and TNFα, irrespective of patients' HLAs. The most immunogenic regions of the vaccine peptide were NY-ESO-189-102 for CD8+ and NY-ESO-183-99 for CD4+ T-cells. We discovered a novel and highly immunogenic epitope (HLA-DR7/NY-ESO-187-99); 7/7 HLA-DR7+ patients generated strong CD4+ T-cell responses, as detected directly ex vivo with fluorescent multimers. Thus, vaccination with the long synthetic NY-ESO-179-108 peptide combined with the strong immune adjuvant CpG-B induced integrated, robust and functional CD8+ and CD4+ T-cell responses in melanoma patients, supporting the further development of this immunotherapeutic approach.

Abstract
The activated sludge process is the most widely used wastewater treatment. The main drawback of this technology is the excess sludge production (ESP). The ozonation of sludge of the recirculation line is used to reduce the ESP. In this study, ozonation was applied on a fraction of sludge of the recirculation line in a full-scale plant (50,000 population equivalent) at a lower-specific ozone dose (SOD) compared to previous studies. The results of batch tests to predict the main effect of the technology on the biomass activities are reported. Specifically, tests at 0.7-5 g O₃/kg MLVSS (mixed liquor volatile suspended solids) doses were made to evaluate the changes of the nitrification and denitrification rates, the population of phosphate-accumulating organisms and the gravitational properties. A certain reduction of the impact of ozonation on the kinetic parameters of sludge for values of SOD over 2 g O₃/kg MLVSS was found. The present study highlights also the use of the ratio of ozonated biomass to total biomass as an important operative parameter for ozonation in full-scale plants. Reduction in ESP in the wastewater treatment plant was equal to 10% as dry solids applying a SOD from 1.03 to 1.63 g O₃/kg MLVSS. An analysis of the economic cost of the technique is also reported.

Abstract
Abstract
Background: Panitumumab is an antibody targeting the epidermal growth factor receptor (EGFR) for which an important role has been suggested in TNBC. Consequently, we evaluated a combination of the standard chemotherapy (FEC 100 followed by docetaxel) with panitumumab as neoadjuvant therapy of operable TNBC. Complete pathologic response (pCR) was the primary endpoint, with clinical response, toxicity, and outcome as secondary endpoints. An investigation of biomarkers possibly predictive of pCR accompanied this trial. Here we focus on tumor recurrence, after a median follow up of 33 months [25-40] as on April, 1, 2013.
Methods: Sixty patients (pts) with stage II-IIIA TNBC were prospectively included. Systemic neoadjuvant treatment (ST) consisted of the anti-EGFR antibody panitumumab combined with FEC 100, followed by 4 cycles of docetaxel. All pts underwent surgery after ST completion. Patient characteristics: median tumor size: 40 mm [20-120]; SBR grade III: 71.7%; pCR rate: 55.3% and 46.8% (the Sataloff and the Chevallier classifications, respectively). Paraffin-embedded and frozen tumor samples were collected before and after ST for biomarker analysis. EGFR, IGF-1R, MET, cytokeratins 5/6 and 8/18, PTEN, P-cadherin, ALDH1, Ki-67, p53, tumoral FOXP3 expression and the number of FOXP3+ or CD8+ tumor-infiltrating lymphocytes (TIL) were evaluated by immunohistochemistry.
Results :.We have observed 9 recurrences: 1 local and 8 distant recidives, including 1 both local and distant.
The distant recidives (metastases) were as follows: brain (4 pts); brain and lungs (1 pt); lungs only (1 pt), pleura (1 pt); liver (1 pt). 6 out of the 8 metastatic pts died and all were non-pCR post-ST. The 2 alive pts had brain metastases, but reached a pCR after the ST.
Among the 9 relapsed pts 6 were 55 years old or less at the diagnosis. Seven out of those 9 pts had tumors with the clinical size equal or higher than 4 cm.
As previously reported (SABCS 2012, abstract 1081), the pCR-predictive biomarkers in this study were high CD8+ TIL count (p = 3.4.10−6) and high ratio between the CD8+ and FOXP3+ TIL counts (CD8+/FOXP3+ > 1.23, p = 8.5.10−5). With this in mind, we have evaluated whether those parameters, assessed before or after the ST, could predict the recurrences. No difference was found in the preoperative CD8+ and the FOXP3+ TIL counts, as well as in the CD8+/FOXP3+ ratio, between the patiens who have recurred and the others.
Conclusion : As it has been reported in previous studies, in our cohort of TNBC pts, the relapses occurred early after the administration of the last systemic treatment. The patients who relapsed died rapidly and most of them have not reached pCR after the ST. In addition, half of the metastatic pts got brain deposits. This implies that research on the resistance factors in TNBC should focus on those important for seeding of the “sanctuaries”, like brain. This research is ongoing in our group.

Abstract
BACKGROUND Dietary treatment for obese adolescents should aim to ensure adequate growth and development, by reducing excessive fat mass accumulation, avoiding loss of lean body mass, improving well-being and self-esteem and preventing cyclical weight regain. The aim of this article is to describe the dietary intervention design and the methods used to evaluate nutritional knowledge and behavior in the EVASYON study (Development, implementation and evaluation of the efficacy of a therapeutic programme for overweight/obese adolescents). METHODS/DESIGN EVASYON is a multi-centre study conducted in 5 Spanish hospital settings (Granada, Madrid, Pamplona, Santander and Zaragoza), where 204 overweight/obese Spanish adolescents were treated in groups of 9 to 11 subjects over 20 visits. The study was implemented in two stages: an intensive, calorie-restricted period for the first 9 weeks, and an extensive body-weight follow-up period for the last 11 months. A moderate energy intake restriction was applied in the intensive period according to the degree of obesity, on the basis of a balanced diet supplying 50-55% of daily energy as carbohydrates; 30-35% as fats and 10-15% as proteins. In the intensive period, adolescents were prescribed both a fixed full-day meal plan for the first three weeks and a full day meal plan with different food-choices for 6 weeks. Later, adolescents received a flexible meal plan based on food exchanges for the follow-up period until the end of the trial. Data on food intake, dietary and meal-related habits and behavior were collected by means of dietary questionnaires. To analyse nutritional knowledge, adolescents were examined regarding nutrient concepts and food adoitems for a healthy diet with the appropriate tools. Participants were given nutritional information with complementary teaching material, which was available on the EVASYON website (www.estudioevasyon.com). DISCUSSION The dietary intervention of the EVASYON programme with a moderate calorie restriction for a limited period of time could be a good strategy in treating overweight and obese adolescents and that will be tested further. Moreover, combining fixed plan with free-choice menus may help adolescents and their families to make right decisions for every day meals.

Abstract
OBJECTIVE To determine the prevalence of voiding dysfunction (VD) in patients with persistent vulvovaginitis (PVV), and to evaluate the clinical response of PVV in the treatment of VD. PATIENTS AND METHODS Girls four years or older who consulted for PVV for at least one month and who did not respond to general measures. A physical examination was performed with visual inspection and colposcopy; vaginal samples for culture and vaginoscopy were carried out. On every patient urodynamic studies were performed. Girls who were diagnosed with VD were treated. A pediatric gynecologist did the follow-up; a successful response was considered when inflammatory symptoms and vaginal discharge ceased. RESULTS Twenty patients were included, mean age 8.6 years (range: 4.6-14 years); 75% prepubertal symptoms lasted for 1.8 years; 19 (95%) had urodynamia, 10 (52.6%) had an overactive bladder, 8 (42.1%) external bladder sphincter dyssynergia, 1 (5.2%) hypotonic bladder, and 13 (65%) showed improvement. CONCLUSION VD is an important cause when considering the etiology of PVV.

Abstract
Intensity-modulated radiation therapy (IMRT) represents one of the greatest technical innovations in modern radiotherapy. Its capacity of achieving treatments with the dose conforming largely to the irradiated area makes it possible to treat volumes close to organs at risk with great safety These characteristics make it an ideal technique for studies, whether for reducing toxicity in organs at risk, or for intensifying dosages to improve the control of the disease. The first part of the article considers what is understood by IMRT and its peculiar dosimetric characteristics, as well the types of IMRT; the second part deals with the clinical evidence in some localisations such as tumours of the head and neck, prostate and breast.

Abstract
BACKGROUND 4 methods are used in pediatric laparoscopic surgery to close trocar wounds. While tissue adhesives or adhesive strips have been shown to produce fewer wound complications and a better cosmetic result compared to trans- or only subcutaneous sutures, the choice of technique is still often based on the surgeon's personal experience. Thus, the objective of this trial was to assess the impact of tissue adhesives (Dermabond™) compared to adhesive strips (Steri-Strip™) on potential complications of wound healing, wound pain, cosmetic outcome, and patient satisfaction after laparoscopic appendectomy in children. METHODS 49 patients undergoing laparoscopic appendectomy were enrolled in this prospective randomized trial. In every patient, two 5-mm and one 10-mm port-site incision was closed either with Dermabond™ or Steri-Strip™ after placing subcuticular absorbable sutures (4-0 Vicryl™). Postoperative complications, pain, and patient satisfaction with scars were evaluated at follow-up on day 10 and day 90 after the operation using a questionnaire and a visual analogue scale (VAS). Photographs of scars taken on day 90 were evaluated on a VAS by 2 pediatric surgeons blinded to the closure method used. RESULTS According to the surgeons' evaluation of the cosmetic outcome, a significant difference between the 2 groups with regard to the cosmetic score was found on day 90 of follow-up, favoring Steri-Strip™ wound closure (p < 0.05). On day 10 and 90 there were no statistical differences between the 2 methods as regards the result of patient evaluations (p > 0.05). Only one wound infection (4%) was observed in the Steri-Strip™ group (n = 25) on day 10. At follow-up on day 90 two patients (9.1%) in the Dermabond™ group and one (4.8%) in the Steri-strip™ group complained of wound pain (p = 0.52). CONCLUSIONS Both tissue adhesives and adhesive strips are excellent "no needle" alternatives for the closure of laparoscopic port-site incisions in children. As regards cosmetic outcome, Steri-Strip™ wound closure seems to be the most suitable and is also the less expensive technique.

Abstract
INTRODUCTION Our studies of clipped intestinal non-perforating anastomosis (CINPA) of the small bowel in a rat model have demonstrated that all clips migrated from the outside to the inside of the small bowel during the healing process. The aim of this study was to describe how the clips migrate. MATERIAL AND METHODS In male Sprague Dawley rats small bowel anastomoses were performed with single, non-perforating metal clips. Bowel specimens were obtained from the anastomosed region for histological examination. RESULTS On the day of surgery all clips were situated in the serous membrane. On the first postoperative day, an intramural migration could be observed. By days 6, 8, and 10 no clip was found in the peritoneum. All egested clips were found either in the distal lumen of the bowel or in the solid feces. H&E staining of the anastomoses studies indicated that the bowel wall everts immediately after being cut and becomes more and more inverted during the first few days after being anastomosed. CONCLUSION Our studies showed that the observed dynamic movement of the bowel wall determines the movement of clip migration from the serosal to the mucosal side of the small bowel. In pediatric surgery the observed clip migration would be an important precondition for employing clipped intestinal non-perforating anastomosis (CINPA) routinely. However, further studies are necessary before the technique can be applied in daily practice.

Abstract
IntroductionInvoluntary admission of mentally ill patients tends to be related to clinical severity and worst therapeutic response.ObjectivesTo evaluate whether there is a relationship between involuntary admission and prescription of two or more antipsychotics (that is, polytherapy) among patients with schizophrenia and other psychosis.MethodsA total of 241 patients (40.2% females, mean age 39.7+/−13.0 years) consecutively admitted during 2009 to a psychiatric inpatient ward with diagnosis of schizophrenia and other psychoses were assessed.ResultsOut of the total sample, 150 (62.2%) patients were on polytherapy, and of the 241 patients 134 (55.6%) were involuntarily admitted. Involuntary admission was unrelated to age (p = 0.335), specific diagnosis (p = 0.452), or length of psychosis (p = 0.234). On the contrary, it was related to gender (61.8% of males vs. 46.4% of females were involuntary, p = 0.018) and to polytherapy/monotherapy prescription (62.0% of patients on polytherapy vs. 45.1% of patients on monotherapy were involuntarily admitted; and 53.3% of voluntary patients vs. 69.4% of involuntary were on polytherapy p = 0.010). After controlling for age, gender, specific diagnosis and length of psychosis the association between involuntary admission and being in polytherapy remained significant (p = 0.047).ConclusionsPatients involuntarily admitted are more prone to be on antipsychotic polytherapy.

Abstract
Many assays to evaluate the nature, breadth, and quality of antigen-specific T cell responses are currently applied in human medicine. In most cases, assay-related protocols are developed on an individual laboratory basis, resulting in a large number of different protocols being applied worldwide. Together with the inherent complexity of cellular assays, this leads to unnecessary limitations in the ability to compare results generated across institutions. Over the past few years a number of critical assay parameters have been identified which influence test performance irrespective of protocol, material, and reagents used. Describing these critical factors as an integral part of any published report will both facilitate the comparison of data generated across institutions and lead to improvements in the assays themselves. To this end, the Minimal Information About T Cell Assays (MIATA) project was initiated. The objective of MIATA is to achieve a broad consensus on which T cell assay parameters should be reported in scientific publications and to propose a mechanism for reporting these in a systematic manner. To add maximum value for the scientific community, a step-wise, open, and field-spanning approach has been taken to achieve technical precision, user-friendliness, adequate incorporation of concerns, and high acceptance among peers. Here, we describe the past, present, and future perspectives of the MIATA project. We suggest that the approach taken can be generically applied to projects in which a broad consensus has to be reached among scientists working in fragmented fields, such as immunology. An additional objective of this undertaking is to engage the broader scientific community to comment on MIATA and to become an active participant in the project.

Abstract
Intimate relationships exist between form and function of plants, determining many processes governing their growth and development. However, in most crop simulation models that have been created to simulate plant growth and, for example, predict biomass production, plant structure has been neglected. In this study, a detailed simulation model of growth and development of spring wheat (Triticum aestivum) is presented, which integrates degree of tillering and canopy architecture with organ-level light interception, photosynthesis, and dry-matter partitioning. An existing spatially explicit 3D architectural model of wheat development was extended with routines for organ-level microclimate, photosynthesis, assimilate distribution within the plant structure according to organ demands, and organ growth and development. Outgrowth of tiller buds was made dependent on the ratio between assimilate supply and demand of the plants. Organ-level photosynthesis, biomass production, and bud outgrowth were simulated satisfactorily. However, to improve crop simulation results more efforts are needed mechanistically to model other major plant physiological processes such as nitrogen uptake and distribution, tiller death, and leaf senescence. Nevertheless, the work presented here is a significant step forwards towards a mechanistic functional-structural plant model, which integrates plant architecture with key plant processes.

Abstract
INTRODUCTION Surgical complications after tumor operations are frequent in children, with rates of up to 30% cited in the literature. Various approaches to reduce these complication rates have been attempted, with preoperative chemotherapy holding pride of place. One approach to minimize surgical complications is better preoperative preparation. In a retrospective analysis, we evaluated the complications associated with tumor surgery. MATERIAL AND METHODS We retrospectively analyzed patient data from 1991 to 2007. The distribution of the various tumors, the type of surgery, and complications were evaluated. For neuroblastomas a differentiated analysis of complications was performed, which included staging and radiologically defined surgical risk factors (SRFs). Patients were divided into two groups: A and B. Intensified surgical planning with 3D visualization was used in patients of group B. RESULTS A total of 145 operations for abdominal tumors were performed in 123 patients. The three most common diseases were neuroblastoma (36%), nephroblastoma (26%), and ovarian tumor (19%). In 68% of patients complete resection and in 19% of cases partial resection of the tumor was carried out; open biopsy was performed in 13%. A total of 15 (10.3%) complications developed: the incidence of complications for group A was 11.8% and 7.7% for group B (p=0.5). For nephroblastoma these figures were 27.9% and 21.2% (p=1.0). In the group of patients with neuroblastoma, six complications developed in patients from group A (21.4%) and one in a group B patient (4.2%) (p=0.107). 54% of neuroblastomas were completely and 33% partially resected; these figures and the distribution of SRFs were similar in the two groups. A significant increase in the risk of complications could be seen with an increase in SRFs (p=0.0267) and with disease stages 2 and 3 (p=0.016). Tumor reduction surgery was also associated with an increase in complications (p=0.086). CONCLUSIONS In summary, tumor surgery is associated with considerable risks in children. Therefore it is very important to look for new approaches that could potentially minimize these risks. As the causes of surgical complications are multifactorial, we are of the opinion that intensified surgical planning can contribute to reducing risks. Particularly neuroblastoma surgery could profit from an increased use of 3D visualization and improved preoperative planning.

Abstract
Intensity-modulated radiation therapy (IMRT) represents one of the greatest technical innovations in modern radiotherapy. Its capacity of achieving treatments with the dose conforming largely to the irradiated area makes it possible to treat volumes close to organs at risk with great safety These characteristics make it an ideal technique for studies, whether for reducing toxicity in organs at risk, or for intensifying dosages to improve the control of the disease. The first part of the article considers what is understood by IMRT and its peculiar dosimetric characteristics, as well the types of IMRT; the second part deals with the clinical evidence in some localisations such as tumours of the head and neck, prostate and breast.

Abstract
OBJECTIVES The EORTC Quality of Life (QL) Group has developed a questionnaire, the EORTC QLQ-PR25, for evaluating QL in prostate cancer. The aim of this study is to assess the psychometric properties of the EORTC QLQPR25 when applied to a sample of Spanish patients. MATERIALS AND METHODS One hundred and thirty-seven prostate cancer patients with localised disease who started radiotherapy with radical intention combined with or without hormonotherapy prospectively completed the EORTC QLQ-C30 and EORTC QLQ-PR25 questionnaires three times: on the first and last day of radiotherapy and in the follow-up period. Psychometric evaluation of the questionnaires' structure, reliability and validity was conducted. RESULTS Multitrait scaling analysis showed that many of the item-scale correlation coefficients met the standards of convergent and discriminant validity. Exceptions appeared mainly in the scales for bowel symptoms and for hormonal- treatment-related symptoms. Cronbach's coefficients of the scales were good (0.72-0.86) for the urinary symptoms and sexual function scales but they were lower (<0.70) for the bowel and hormonal treatment scales. Most scales of the EORTC QLQ-PR25 had low to moderate intercorrelations. Correlations between the scales of the QLQ-C30 and the module were generally low. Group comparison analyses showed better QL in patients with higher Performance Status. Changes in QL appeared throughout the measurements. These were in line with the treatment process. CONCLUSIONS The EORTC QLQ-PR25 was a reliable and valid instrument when applied to a sample of Spanish prostate cancer patients. These results are in line with those of the EORTC validation study.
