Abstract
PURPOSE To compare the detection of human cytomegalovirus (HCMV) in bronchoalveolar lavage (BAL) fluid by viral culture and quantitative polymerase chain reaction (qPCR), and to establish a viral load threshold that can identify cases of HCMV replication indicative of pneumonitis. There is currently no universal viral load cut-off to differentiate between patients with and without pneumonitis, and the interpretation of qPCR results is challenging. METHODS 176 consecutive BAL samples from immunosuppressed hosts with signs and/or symptoms of respiratory infection were prospectively studied by viral culture and qPCR. RESULTS Concordant results were obtained in 81.25% of the BAL samples. The rest were discordant, as only 34% of the qPCR-positive BAL samples were positive by culture. The median HCMV load was significantly higher in culture-positive than in culture-negative BAL samples (5,038 vs 178 IU/mL). Using a cut-off value of 1,258 IU/mL of HCMV in BAL, pneumonia was diagnosed with a sensitivity of 76%, a specificity of 100%, a VPP of 100% and VPN of 98%, and HCMV was isolated in 100% of the BAL cultures. CONCLUSION We found that a qPCR-negative was a quick and reliable way of ruling out HCMV pneumonitis, but a positive result did not always indicate clinically significant replication in the lung. However, an HCMV load in BAL fluid of ≥1,258 IU/mL was always associated with disease, whereas <200 IU/mL rarely so.

Abstract
INTRODUCTION Obstructive sleep apnea (OSA) has been proposed as a factor that worsens stroke prognosis. Our aim was to determine if an OSA intervention could improve quality of life (QOL, first objective) and modified Rankin score (mRS, second objective). PATIENTS AND METHODS The intervention group of this quasi-experimental study included patients with acute ischemic stroke <72 hours who underwent polygraphy and Continuous Positive Airway Pressure (CPAP) and hygienic-dietary measures if required. The control group followed routine clinical practice. The Short Form 36 Health Survey (SF-36) and mRS were applied at the sixth month after stroke in both groups. RESULTS Fifty-five vs. sixty-two patients were included in the intervention and control group respectively. In the intervention group, 64.71% of patients accepted the proposed CPAP (16 cases with a good adherence). An improvement in SF-36 items was detected in the intervention group: physical functioning (p = 0.008), role physical (p = 0.002), bodily pain (p = 0.008), general health (p <0.001), vitality (p = 0.001) and role emotional (p = 0.015). In a per-protocol analysis, all these improvements were verified in the group of patients treated with good CPAP adherence (p < 0.05 in all the same SF-36 items). The percentage of patients with physical component summatory = 50 was higher in the intervention group (p = 0.003). There were no differences in the median of mRS (p = 0.262). CONCLUSIONS Although more evidence is needed, a significant improvement in QOL was suggested after our OSA intervention, particularly in patients with good CPAP adherence.

Abstract
Quantum materials are notoriously sensitive to their environments, where small perturbations can tip a system toward one of several competing ground states. Graphene hosts a rich assortment of such competing phases, including a bond density wave instability ("Kekulé distortion") that couples electrons at the K/K' valleys and breaks the lattice symmetry. Here, we report observations of a ubiquitous Kekulé distortion across multiple graphene systems. We show that extremely dilute concentrations of surface atoms (less than three adsorbed atoms every 1000 graphene unit cells) can self-assemble and trigger the onset of a global Kekulé density wave phase. Combining complementary momentum-sensitive angle-resolved photoemission spectroscopy (ARPES) and low-energy electron diffraction (LEED) measurements, we confirm the presence of this density wave phase and observe the opening of an energy gap. Our results reveal an unexpected sensitivity of the graphene lattice to dilute surface disorder and show that adsorbed atoms offer an attractive route toward designing novel phases in two-dimensional materials.

Abstract
All disc-accreting astrophysical objects produce powerful disc winds. In compact binaries containing neutron stars or black holes, accretion often takes place during violent outbursts. The main disc wind signatures during these eruptions are blue-shifted X-ray absorption lines, which are preferentially seen in disc-dominated 'soft states'1,2. By contrast, optical wind-formed lines have recently been detected in 'hard states', when a hot corona dominates the luminosity3. The relationship between these signatures is unknown, and no erupting system has as yet revealed wind-formed lines between the X-ray and optical bands, despite the many strong resonance transitions in this ultraviolet (UV) region4. Here we report that the transient neutron star binary Swift J1858.6-0814 exhibits wind-formed, blue-shifted absorption lines associated with C IV, N V and He II in time-resolved UV spectroscopy during a luminous hard state, which we interpret as a warm, moderately ionized outflow component in this state. Simultaneously observed optical lines also display transient blue-shifted absorption. Decomposing the UV data into constant and variable components, the blue-shifted absorption is associated with the former. This implies that the outflow is not associated with the luminous flares in the data. The joint presence of UV and optical wind features reveals a multi-phase and/or spatially stratified evaporative outflow from the outer disc5. This type of persistent mass loss across all accretion states has been predicted by radiation-hydrodynamic simulations6 and helps to explain the shorter-than-expected duration of outbursts7.

Abstract
INTRODUCTION Neonatal airway examination through flexible/rigid bronchoscopy has proved to be useful in the presence of persistent stridor and extubation failure, as well as to assess complications following cardiac surgery. At our institution, these examinations are carried out by a pulmonologist, a neonatologist, an otorhinolaryngologist, and a pediatric surgeon from the pediatric airway committee, established in 2014. OBJECTIVE To analyze the airway examinations performed in neonates during their stay at the neonatology/neonatal intensive care unit since the airway committee was established. MATERIAL AND METHODS A retrospective study of the airway examinations conducted in neonates from 2015 to 2019 was carried out. Clinical and demographic data, number of examinations, indications, findings, and complications were collected. Results are presented as mean and standard deviation. Statistical significance was established at p < 0.05. RESULTS 92 airway examinations were analyzed in 51 patients (54.9% of whom were female). 51% of the patients were premature. Extubation failure and persistent respiratory symptoms following successful extubation were the most frequent indications for airway examination (35.3%). Stratification by gestational age or weight at birth was not associated with an increased risk of pathological findings at examination (p > 0.05). The most frequent finding was vocal cord paralysis (n = 14; 27.5%). In 10 patients (19.6%), no pathological findings were observed. CONCLUSION Airway examination is useful in patients with stridor to identify vocal cord paralysis following extubation failure. It also allows congenital airway pathologies to be diagnosed and treated. The number of examinations with no pathological findings was similar to that reported in international series.

Abstract
BACKGROUND In our country, transplantation centers differ in the age limit for allogeneic hematopoietic transplantation (ALOHT). In our program, transplants with age- adjusted conditioning are performed in patients until 70 years old. Currently more than 60% of ALOHT reported to the Center for International Bone Marrow Transplantation Research (CIBMTR) are performed in patients older than 40 years. AIM To report our experience with ALOHT in acute myelogenous leukemia (AML), analyzing patient age at transplantation in different periods and transplant results in different age groups. MATERIAL AND METHODS A retrospective analysis of the database of adult hematopoietic transplants in AML patients was performed. Demographic data, disease characteristics, transplant data, survival and relapse times, and mortality were collected. RESULTS In our program, 1030 transplants were performed in adults and 119 ALOHT were performed in AML patients, between 1990 and 2020. The median age of patients in all periods was 41 years, (range 16-69). The median age was 33 and 45 years, in the periods 1990-2000 and 2000-2020 respectively (p < 0.01). Seventy-eight patients received myeloablative conditioning (median age 44 years) and 41 reduced intensity conditioning (median age 53 years). Five-year overall survival was 44.6% (confidence intervals (CI) 41-48). Non relapse mortality of all periods was 19% (CI 17 - 40%) and relapse rate was 17 % (CI 16-22). No difference in five years overall survival among patients younger than 40, 41 to 50 and over 51 years was observed. CONCLUSIONS Overall Survival, non-relapse mortality and relapse rate were similar in younger and older patients in our program and similar to those previously reported in other centers.

Abstract
INTRODUCTION Recurrent tracheoesophageal fistula (RTEF) is a frequent complication (5-10%) in patients with esophageal atresia (EA). Open RTEF surgery has a high morbidity and mortality, so the endoscopic approach represents a promising alternative. We present the long-term results of fibrin glue (FG) bronchoscopic application in patients with RTEF secondary to EA, which was first used by our team in 1994. MATERIAL AND METHODS A retrospective review of all patients diagnosed with RTEF following EA repair and treated with FG bronchoscopic application from 1993 to 2019 was carried out. In most cases, diathermy was applied prior to FG sealing. The maximum number of endoscopic sessions was 5. In case of persistent RTEF following the fifth session, open surgery was performed. RESULTS 14 RTEF patients were treated with FG. In all but the first 3 cases (11 patients, 78.6%), diathermy was applied concomitantly. Mean first treatment day was day 85 of life (range: 14-770). Patients received a mean of 2.1 (1-5) endoscopic sessions. Mean follow-up was 12.1 (10-20) years. Overall success rate was 71.4%, without significant differences according to whether diathermy was concomitantly applied or not (72.7% vs. 66.6%). CONCLUSIONS Fibrin glue bronchoscopic application associated or not associated with diathermy is an excellent option for RTEF treatment in EA patients. The endoscopic approach should be considered as the first-choice treatment for RTEF.

Abstract
Graphene is a powerful playground for studying a plethora of quantum phenomena. One of the remarkable properties of graphene arises when it is strained in particular geometries and the electrons behave as if they were under the influence of a magnetic field. Previously, these strain-induced pseudomagnetic fields have been explored on the nano- and micrometer-scale using scanning probe and transport measurements. Heteroepitaxial strain, in contrast, is a wafer-scale engineering method. Here, we show that pseudomagnetic fields can be generated in graphene through wafer-scale epitaxial growth. Shallow triangular nanoprisms in the SiC substrate generate strain-induced uniform fields of 41 T, enabling the observation of strain-induced Landau levels at room temperature, as detected by angle-resolved photoemission spectroscopy, and confirmed by model calculations and scanning tunneling microscopy measurements. Our work demonstrates the feasibility of exploiting strain-induced quantum phases in two-dimensional Dirac materials on a wafer-scale platform, opening the field to new applications.

Abstract
This paper presents a study carried out to determine the feasibility to obtain bioethanol from an industrial algae waste. The influence of some parameters on acid hydrolysis was studied. The results indicated that the overall hydrolysis ability is a function of the combined action of acid concentration, temperature and reaction time. The hydrolysates with higher amount of reducing sugars were used for ethanolic fermentation using S. Cerevisiae. The highest bioethanol yield 11.6 gEtOH/galgae was obtained at 70 min, a sulphuric acid concentration of 9% wt. and acid/dried algae ratio of 7. The present study showed that the industrial waste of Euchema Spinosum contains carbohydrates that can be converted into bioethanol with an efficiency of 75%. Moreover, the potential of the residue after acid hydrolysis process as sustainable solid fuel regarding its properties was analysed. The results were compared with those obtained from the literature and discussed according to international standards.

Abstract
INTRODUCTION Pediatric subglottic pathology still represents a challenge when it comes to choosing the right treatment. We present the management of patients followed in our center for this reason during the last 5 years. MATERIAL AND METHODS Retrospective study of patients followed by glotosubglottic pathology (stenosis, cysts or granulomas) between 2011 and 2016 in a third level hospital. RESULTS Twenty-seven patients were included in the review. Treatment options varied according to the nature, location and severity of the subglottic stenosis. Two patients with congenital subglottic stenosis were treated by laryngotracheoplasty. Seventeen patients with acquired subglottic stenosis were included: in one (5.9%) laryngotracheoplasty was performed, one (5.9%) received cricotracheal split, two of them (11.8%) underwent partial cricotracheal resection (PCTR) , seven patients (41.2%) underwent microsurgery, three (17.6%) received tracheal dilatation, and the last three (17.6%) were submitted to observation without needing further treatment. Five patients with post-intubation subglottic cysts received microsurgery. Of three patients diagnosed with post-intubation subglottic granuloma, two (66%) resolved spontaneously and one (33%) required microsurgery. CONCLUSIONS Management of pediatric subglottic pathology remains a major challenge. Since the creation of the Airway Committee in our center, the improvement in the management of these patients has led to a multidisciplinary management, with the consequent impact on the clinical results.

Abstract
BACKGROUND One of the most critical points in the planning of hip replacement surgeries is the selection of the implant, since its survival significantly impacts the patients health. However, the ideal survival time that an implant must prove to be selected has not been defined. The objective of this consensus is to define minimum performance standards for the selection of conventional primary hip replacement prosthesis. MATERIAL AND METHODS The consensus was carried out using the methodology of nominal group. This included: 1. A review of the available evidence and the issues to be evaluated, 2. Meeting for the vote and discussion, 3. Quantitative statistical analysis with median (M) and interquartile range (IQR) and qualitative one with proportions of the results to generate recommendations. RESULTS The primary source of information for prosthesis selection (M: 8; IQR: 7-9), choice in the event of conflicting evidence (M: 8; IQR: 7-9), or limited evidence in the literature (M: 7; IQR: 4.75-825) should be national registries. The minimum acceptable follow-up is 10 years (M: 9; IQR: 8-9) and the minimum acceptable survival is 90% at 10 years (M: 8; IQR: 5-8.5). DISCUSSION According to these results, the consensus of experts proposed that the selection of the implant for conventional primary hip replacement must be based on the information published in the national registries and that the prosthesis must have a minimum follow-up of 10 years and show a minimum survival of 90%.

Abstract
BACKGROUND Examine the evolution of stunting in <5 years of age in Peru and its relationship with birth interval (BI), and associated factors from 1996 to 2014. METHODS Data were extracted from the National Demographic and Health Survey of Peru (DHS) for the years 1996, 2000, 2005, 2010 and 2014 on children <5 years of age for stunting (height / age ≤ 2DS). The main independent variable of interest was BI dichotomized by interval between date of last and penultimate birth (≤24 months vs. >24 months) and others sociodemographic variables. Crude and adjusted odds ratios with 95% confidence intervals were estimated in logistic regression for the effect of BI and other variables on stunting by each survey year. RESULTS Between 1996 and 2014, stunting declined in both BI groups: ≤24 months: 35.8% to 21.8%; >24 months: 29.5% to 14.3%. BI was associated with stunting after adjustment for other variables in each survey except 2005. Of the other factors, sex, birth order (fourth child or more), maternal education and poverty were independently associated with stunting in all survey years. Residence in rural areas and in Amazon forest and highland regions was associated with stunting 1996 and 2000. Maternal age was not independently associated with stunting. CONCLUSIONS While stunting showed a decreasing trend from 1996 to 2014, birth interval exceeding 24 months exerted a protective effect on stunting across the years surveyed. Poverty, low maternal education and high birth order were associated with stunting in all survey years.

Abstract
The present work was planned to research epidemiological and immunological features of systemic lupus erythematosus (SLE) in a Caucasian population from the north of Spain (Asturias). There is only one specialized immunology laboratory in this region where samples from all patients with a plausible or a firm diagnosis of SLE are referred for immunological analysis. Since 1992 we have reviewed registered data from samples submitted to the immunology laboratory with a firm, definitive diagnosis of SLE, based on the fulfillment of the American College of Rheumatology (ACR) criteria. We have constructed a database, which included 367 SLE patients. The point prevalencewas 34.12/100 000 (95% CI: 30.63-37.61/100 000), whereas the incidence rate calculated during the last five years was 2.15/100 000/year (95% CI: 1.76-2.54/100 000/year). The female/male ratio varied according to the age at diagnosis, being maximum (50: 1) between 22 and 28 years. The median age at diagnostis was significantly lower in females than in males. Immunological features also yielded sex and age peculiarities. The percentage of patients with anti-SSa antibodies yielded significant differences between males (18.6%) and females (34.6%). Anti-RNP and anti-Sm antibodies were more frequently present in childhood-onset patients, the difference with the oldest-onset group being statistically significant. Other analyses did not show significant differences, although, as a whole, we observed a trend towards a higher presence of autoantibodies related to an early disease onset.

Abstract
AimsThe aim of this study was to compare transscleral resection technique performed without hypotensive anaesthesia (TSRWH) with iodine-125 brachytherapy (IBT) in the treatment of choroidal melanoma.Patients and methodsThis was a retrospective surgical cohort study. Nineteen eyes treated with TSRWH were matched with 53 eyes treated with IBT according to: tumour size, distance to fovea, distance to optic nerve, and follow-up time. Best-corrected visual acuity (BCVA), local recurrence, secondary enucleation, metastasis, overall and specific survival, and complications were evaluated.ResultsPatients treated with TSRWH had significantly better BCVA than those treated with IBT. The local recurrence risk was significantly higher when ciliary body was involved (HR=11.4, 95% CI 2.24-49.7, P=0.04). Metastatic disease was observed in 14 of 53 patients (26.4%) in the IBT group vs 3 patients (15.8%) in the TSRWH group (P=0.531). Multivariate analysis showed that iris involvement (HR=16.0, 95% CI 4.2-170.2, P=0.033) and large tumour (HR=2.3, 95% CI 1.2-4.8, P=0.04) increased the probability of metastasis. During follow-up, six patients (11.3%) in IBT group died vs two (10.5%) in the TSRWH group (P≥0.999). Nine patients required secondary enucleation: 5 (9.4%) in the IBT group vs 4 (21.1%) in the TSRWH group (P=0.231). The most common complications in IBT group were radiation-induced retinopathy (45.3%), neovascular glaucoma (28.3%), and macular oedema (24.5%), whereas rhegmatogenous retinal detachment (21.1%), ocular hypertension (21.1%), and submacular haemorrhage (15.8%) were the most frequent complications after TSRWH.ConclusionTSRWH is a technically challenging procedure. However, when performed successfully, this technique achieves better preservation of visual acuity than IBT and without the limitations inherent in hypotensive anaesthesia.

Abstract
INTRODUCTION Recent studies have demonstrated a relationship between low-grade proteinuria and worse graft survival, but this has not been fully studied in expanded criteria donor (ECD) kidney transplant recipients. AIM The aim of this study was to assess whether the combination of early low-grade proteinuria (<1 g/d) and allograft dysfunction at the third month post-transplantation predicts outcomes in terms of survival in ECD kidney transplant recipients. MATERIAL AND METHODS We studied a cohort of 269 ECD kidney transplant recipients subdivided into 4 groups according to clinically relevant proteinuria (300 mg/d) and median creatinine (Cr; 1.7 mg/dL; interquartile range, 1.4-2.1 mg/dL) at the third month post-transplantation: Group A (Cr <1.7 mg/dL and proteinuria <300 mg/24 h; n = 97), Group B (Cr <1.7 mg/dL and proteinuria ≥300 mg/24 h; n = 38), Group C (Cr ≥1.7 mg/dL and proteinuria <300 mg/24 h; n = 79), and Group D (Cr ≥1.7 mg/dL and proteinuria ≥300 mg/24 h; n = 55). RESULTS Death-censored graft survival was significantly lower in Group D compared with the rest (P < .007). Multivariate Cox regression analysis using fixed covariates showed that the combination of low-grade proteinuria and a lower estimated glomerular filtration rate (eGFR) as associated with graft failure (hazard rate [HR] 2.5, 95% confidence interval [CI], 1.09-5.97; P = .03). CONCLUSIONS The early association of low-grade proteinuria and allograft dysfunction represents an important risk factor for graft loss in ECD kidney transplant recipients. Strategies to optimize renal function could improve the outcome in this specific population.

Abstract
AIM Vascular rings are a rare cause of compression of the trachea and/or the esophagus, causing stridor and/or severe dysphagia. We present our experience in the diagnosis and management of vascular rings. METHODS Retrospective study in which we analyzed clinical history, diagnosis and management of 18 patients diagnosed with vascular ring between January 1985 and December 2013. We evaluate endoscopy as a diagnostic method. RESULTS A total of 18 patients were included, with a median age of 2 years. 83.3% (15/18) had some type of symptom: 46.7% (7/15) had respiratory symptoms such as respiratory distress, stridor, recurrent respiratory infections, bronchospasm with wheezing or asthma in older children; 20% (3/15) had digestive symptoms such as dysphagia, vomiting and regurgitation; and 33.3% (5/15) combined respiratory and digestive symptoms. The remaining patients, 16.7% (3/18) were asymptomatic and the diagnosis was casual. The most common types of vascular rings were double aortic arch (27.8%) and aberrant subclavian right artery (27.8%). In 3 cases (16.7%) a Kommerell diverticulum was associated. 44.4% (n = 8) was operated on, the remaining did not present symp- toms which justify the intervention (n = 10). 37.5% of patients had postoperative complications (iatrogenic recurrent paralysis and persistent tracheomalacia). There was no mortality in our series. The median follow-up was 6.4 years. At the moment, 88.9% of patients are asymptomatic, and 33.3% have been definitely discharged. CONCLUSIONS Vascular rings are rare, and usually presented with common symptoms in childhood. Therefore, in front of a longstanding and recurrent respiratory symptoms, or dysphagia, we should think of a vascular ring. Not all subjects are candidates for surgical correction; therefore a multidisciplinary evaluation is essential.

Abstract
In 2008, Trypanosoma evansi was detected on a camel farm in mainland Spain. The animals were isolated, confined in a closed stable, and treated twice with melarsamine (Cymelarsan(®), Merial, Lyon, France) with an interval of 1 month. Clinical and laboratory examinations by means of parasitological, serological, and molecular procedures (polymerase chain reaction (PCR)) were carried out regularly for 6 years. After the treatment, all parasitemic camels were cleared of parasites, and in the seropositive camels a progressive decrease in antibody levels was observed, with complete disappearance of antibodies between 15 and 21 months, except in one animal which showed doubtful Ag-Ab reaction at 21 months post treatment. In the next assessment, 6 months later, the diagnostic tests conducted on all animals had a negative result. The diagnostic and therapeutic tools recently developed against T. evansi will evidence new and alternative approaches after the parasite is detected, particularly if outbreak occurs in geographically localized areas in territories free of the disease.

Abstract
OBJECTIVES In view of the fact that mucosal damage associated with HIV-1 infection leads to microbial translocation despite successful antiretroviral treatment, we analysed microbial translocation and expression of the gut-homing β7 receptor on peripheral T cells in HIV-1-infected individuals. METHODS Fifteen long-term suppressed HIV-1-infected patients, of whom seven had their treatment intensified with maraviroc and eight with raltegravir, were included in the study. Samples at baseline, at week 48 of intensification, and at weeks 12 and 24 after deintensification were analysed for soluble CD14, lipopolysaccharide (LPS), LPS-binding protein, gut-homing β7 receptor and T-cell subsets. RESULTS The increases in both microbial translocation and expression of the gut-homing β7 receptor on activated CD8 T cells found during maraviroc intensification were reduced after deintensification. Moreover, the correlations between activated β7(+) T cells and LPS levels found during intensification with maraviroc (P = 0.036 and P = 0.010, respectively) were lost during deintensification. In contrast, microbial translocation was stable during raltegravir intensification, with the exception of decreased LPS levels and activated CD4 β7(+) T cells, which reverted to baseline values after deintensification. CONCLUSIONS Microbial translocation is an important factor in gut immune activation and mucosa inflammation, as evidenced by the association between the dynamics of microbial translocation and activated T cells expressing the gut-homing β7 receptor. The recruitment of activated β7(+) T cells to the gut tract when alteration of microbial translocation is maximum may be the major mechanism for recovery of mucosal integrity.

Abstract
GOALS To estimate the prevalence, age distribution, impact on quality of life and type of urinary incontinence (UI) in women over 30 years in Mallorca (Spain). MATERIAL AND METHODS Cross-sectional descriptive study on a randomized sample of 673 women in the health district affiliated to Son Llàtzer Hospital and the 14 Community Health Centres on its area of influence. Following an invitation to participate in the study, women were interviewed twice by their Community Nurse, through the phone and face-to-face. Every interview comprised the completion of the Spanish versions of the ICIQ-SF and EuroQol-5D questionnaires. Prevalence, type and severity (ICIQ-SF) of UI, previous health history and quality of life of women suffering from and free from UI were all estimated. RESULTS 24% (CI 95%=20.9-27.5%) of women suffered from UI and prevalence increased significantly with age. Most frequently identified type of UI was stress incontinence (45%) followed by mixed incontinence (29%), urge incontinence (19.4%) and continuous incontinence (6.5%). For women suffering from UI, ICIQ-SF mean total score was 9.2, 25.2% of these suffering from moderate to severe UI. Women suffering from mixed or continuous UI scored highest at ICIQ-SF. Women suffering from UI showed worse quality of life in every dimension of EuroQol-5D. Quality of life was especially poor for women suffering from mixed or continuous UI. CONCLUSIONS One in four women suffers from UI. UI prevalence increases with age. Half of identified women suffered from stress UI. A fourth of identified incontinences were described as moderate to severe. Women suffering from UI showed worse quality of life.

Abstract
PURPOSE. To submit the short and long term results of long-gap esophageal atresia (EA) with two surgical techniques. METHODS. We carried out a retrospective study of long-gap type EA without fistula (n=8) and with fistula (n=2) over the last 18 years, comparing the outcome of the Schärli technique (1992) with that of the Foker technique (1997). RESULTS. We included 10 patients with long gap EA. Mean birth weight was 2,418 grams. 30% had associated diseases (VACTERL, Down Syndrome, DiGeorge Syndrome). Gastrostomy or jejunostomy was initially placed in 7 patients. Schärli technique was performed in 4 patients (mean age: 3.3 months), and Foker technique in 6 patients (median age: 23.5 days of life). Complications were: a) Schärli: dehiscence (25%), stenosis (75%), one patient died from his heart disease (25%), colonic herniation through diaphragmatic hiatus (25%). The mean number of stricture dilatations was 7 sessions (S.D. 9.2). a) Foker: dehiscence (83.3%), stenosis (83.3%), gastroesophageal reflux (GER) (83.3%), fistula (16.7%). Mean number of dilatations was 13.7 sessions (S.D. 12.8). All patients operated on with Schärli technique (6-18 years, median follow-up 12 years) were asymptomatic at the time of the study, although one of them had grade III esophagitis in the last biopsy. As for the Foker's, 5 had undergone antireflux surgery and only one was asymptomatic. The rest had complications that were still being treated (stenosis and development of fistulae). CONCLUSION. Treatment of long gap EA remains a surgical challenge. In our experience patients developed fewer complications with the Schärli technique. Nevertheless, it is difficult to make a comparison with such a limited number of patients.

Abstract
A two-dimensional bisexual branching process has recently been presented for the analysis of the generation-to-generation evolution of the number of carriers of a Y-linked gene. In this model, preference of females for males with a specific genetic characteristic is assumed to be determined by an allele of the gene. It has been shown that the behavior of this kind of Y-linked gene is strongly related to the reproduction law of each genotype. In practice, the corresponding offspring distributions are usually unknown, and it is necessary to develop their estimation theory in order to determine the natural selection of the gene. Here we deal with the estimation problem for the offspring distribution of each genotype of a Y-linked gene when the only observable data are each generation's total numbers of males of each genotype and of females. We set out the problem in a non parametric framework and obtain the maximum likelihood estimators of the offspring distributions using an expectation-maximization algorithm. From these estimators, we also derive the estimators for the reproduction mean of each genotype and forecast the distribution of the future population sizes. Finally, we check the accuracy of the algorithm by means of a simulation study.

Abstract
A new two-sex bidimensional branching process is introduced to model the evolution of the number of carriers of an allele and its mutations of a Y-linked gene. A population is assumed in which females and males coexist and mate without the gene influencing the mating process. It is deduced from the model that the key determining conditions for the extinction or survival of the allele are given by the probability that an offspring is female, the rate of mutation, and the mean number of offspring per mating unit. It is also proved that the destiny of the allele's mutations in the population also depends on the survival or extinction of the original allele.

Abstract
The aim of this paper is to describe and evaluate the benefits of epidural anesthesia in major surgery neonatal. We have performed a matched case-control (2:1) study of patients undergoing neonatal major surgery (NMSs) who received intra-and postoperative epidural anesthesia (EA) and controls with conventional general anesthesia. The matching criteria were age, weight and baseline pathology. EA was administered by caudal puncture and epidural catheter placed with ultrasound support. Levobupivacaine was selected as anesthetic drug. The time to extubation, intestinal transit time, type of analgesia and complications were studied. This study is based on 11 cases (2 esophageal atresia, 2 diaphragmatic hernias, 1 necrotizing enterocolitis, 3 intestinal atresia, 2 anorectal malformation and 1 bladder exstrophy) and 22 controls. We observed statistically significant differences in time to extubation (95% CI OR 12 1.99 to 72.35; Chi2 p = 0.004, Mann U Whytney p = 0.013) and intestinal transit time (Mann Whitney U p < 0.001, 100 Or, 95% CI 8.06-1 239; Chi2 p < 0.0001). There were no complications from epidural analgesia. Therefore we believe that the intra-and postoperative EA helps improve postoperative management in neonates and should be preferred in centers where this technique is available.

Abstract
INTRODUCTION Despite tumour cell dissemination through the intraprostatic nervous system being considered as a prostate cancer progression mechanism, the significance of perineural invasion in prostate biopsies to predict extraprostatic extension and its use as a potential prognosis factor is controversial. MATERIALS AND METHODS Retrospective study carried out at an institution on 208 patients treated with radical prostatectomy (January 2007 - July 2010) in which the presence of perineural invasion and the Gleason score in the preoperative biopsy were determined, as well as the clinical stage and the pre-surgery PSA. We classified the patients in risk groups in accordance with the D'Amico classification. We performed bivariate and multivariate statistical analyses to establish the correlations between the different variables. RESULTS We objectified PNI in 18.3% of the prostate biopsies. 71% of the prostatectomy specimens with perineural invasion presented extraprostatic extension in the previous biopsy against 23.1% when this was not found (p<0.0001) and 47% of the cases showed positive margins with PNI, against 18.3% without perineural invasion (p<0.0001). In fact, in the multivariate analysis, perineural invasion proved to be an independent risk factor in the presentation of extraprostatic extension and positive margins in the prostatectomy specimen. CONCLUSIONS The presence of perineural invasion is a useful prognostic factor for predicting extraprostatic extension and the involvement of surgical margin in the radical prostatectomy specimen. We believe that determining it may be a useful tool for improving preoperative diagnosis and planning treatment.

Abstract
The limiting genotype growth rates and the limiting genotype frequencies of Y-linked genes are studied in a two-sex monogamous population. To this end, the evolution of the numbers of females, males, and mating units of each genotype is modelled by a multitype bisexual branching process in which it assumed that the gene has no influence on the mating process. It is deduced from this model that the average numbers of female and male descendants per mating unit of a genotype determine its growth rate, which does not depend on the behaviour of the other genotypes. Hence, the dominant genotype is found. Conditions for the simultaneous survival of genotypes to have positive probability are also investigated. Finally, the main results are illustrated by means of examples.

Abstract
Trypanosoma evansi was diagnosed for the first time in camels in the Canary Islands in 1997. Several sanitary measures including treatment of infected animals were taken; however, nowadays a little area is still infected. In order to determine possible reservoirs 138 wild rodents were trapped, 64 of them in the infected farms and the remaining 74 in other areas. The captured species were Rattus rattus (24), Rattus norvegicus (69) and Mus musculus domesticus (45). Serological (CATT/T. evansi), parasitological (micro-Hematocrit Centrifugation technique and stained smears) and molecular (PCR) methods for T. evansi and T. lewisi were used as diagnostic methods. None of the examined rodents was positive for T. evansi; 18, however, showed motile trypanosomes at micro-Hematocrit Centrifugation technique and resulted positive for T. lewisi by PCR. The results would suggest that the studied rodent species would not play a relevant role in the epidemiology of T. evansi infection in Canaries.
