AIM: The aim of this work was to evaluate the concordance between the low anterior resection syndrome (LARS) and preoperative LARS (POLARS) scores regarding the incidence of LARS in a Chilean population undergoing rectal surgery for cancer in a high-volume hospital. METHOD: The LARS score questionnaire, following telephone requests, was used to determine the presence and severity of LARS. The POLARS score was calculated based on variables described previously. Correlations and qualitative and quantitative concordance were evaluated using Spearman's correlation coefficient, the kappa coefficient and the Bland-Altman plot with Lin's concordance correlation coefficient. RESULTS: A total of 120 patients met the inclusion criteria: 37.5% underwent neoadjuvant radiotherapy, 61% underwent total mesorectal excision (TME) and 51.6% underwent ostomy. A total of 49% of patients did not present with LARS, whereas 28% had major LARS. The correlation between scales was poor, with a fair qualitative concordance to determine the presence/absence of LARS and a slight qualitative concordance to determine the degree of the intensity. The quantitative concordance was poor. CONCLUSION: In the Chilean population, concordance between the LARS and POLARS scores was qualitatively fair to determine the presence/absence of the disease and qualitatively slight to determine the degree of intensity. We do not suggest using the POLARS score in the perioperative period in the Chilean population deliberately, as the score may help to determine the presence/absence of LARS but cannot determine its degree of intensity. Additional evaluations are required to determine the factors contributing to the degree of agreement between the scales.

OBJECTIVE: This article tests the protective effect of a commercially available mixture of hyaluronic acid, chondroitin sulfate, and poloxamer 407 on the damage caused by the exposure of esophageal mucosa to button batteries in an animal model. METHODS: Experimental study. Sixty porcine esophageal samples were distributed in three groups: control (CG), exposure (EG), and exposure-protection (EPG). In EG and EPG, one CR2032 button battery per sample was inserted, both were subdivided into 2-, 4-, 6-, and 24-hour exposure subgroups, with subsequent battery removal. EPG samples were irrigated with the solution 1 hour after battery exposure. Esophageal pH and final voltage of the battery were measured. RESULTS: pH in CG remained stable. No significant differences in pH at 1 hour were found between EG and EPG. In EPG, the pH of the mucosa exposed to the anode was lower than in GE at 2 hours (12.44 vs. 11.89, p = 0.203) and 4 hours (13.78 vs. 11.77, p < 0.0001). In the cathode pH was significantly higher in EG at 2 hours (2.5 vs. 4.11, p < 0.0001), 4 hours (2.33 vs. 4.78, p < 0.0001), and 6 hours (2.17 vs. 2.91, p < 0.0001). Significant voltage reduction at 1 hour was found in EG compared to EPG (0.48 vs. 1.08 V, p = 0.004). CONCLUSION: Exposure to hyaluronic acid solution buffers the acidification on the side exposed to the cathode and basification on the anode. This effect can be maintained up to 3 to 5 hours, even after stopping its application. Our results suggest that a solution containing hyaluronic acid could be used as an esophageal protector after accidental ingestion of button batteries.

OBJECTIVE: The objective of this study was to analyze whether patients undergoing esophageal atresia (EA) surgery benefit from a cross-disciplinary follow-up program, based on current clinical guidelines, implemented in our institution. MATERIALS AND METHODS: An observational, analytical, retrospective study of patients undergoing EA surgery from 2012 to 2022 was carried out. The results of a joint pediatric surgery and gastroenterology consultation program -which was implemented in 2018 and applies a protocol based on the new ESPGHAN-NASPGHAN guidelines- were analyzed. Patients were divided according to whether they had been treated before or after 2018. Quantitative variables -follow-up losses, anti-reflux treatment initiation and duration, and enteral nutrition initiation- and qualitative variables -prevalence of gastroesophageal reflux, anti-reflux surgery, respiratory infections, anastomotic stenosis, re-fistulizations, dysphagia, impaction episodes, need for gastrostomy, and endoscopic results- were compared. RESULTS: 38 patients were included. 63.2% had gastroesophageal reflux. 97.4% received anti-reflux treatment in the first year of life, with treatment being subsequently discontinued in 47.4%. Discontinuation time decreased by a mean of 24 months following program implementation (p< 0.05). A 4.6-fold increase in the frequency of pH-metries was noted following program implementation. The protocol standardized endoscopies in asymptomatic patients when they turn 5 and 10 years old. 25 endoscopies with biopsy were carried out after 2018, with histological disorders being detected in 28% of them. The number of follow-up losses significantly decreased following protocol implementation (p< 0.05). CONCLUSIONS: Digestive-surgical cross-disciplinary follow-up of EA patients has a positive impact on patient progression. Applying the guidelines helps optimize treatment and early diagnosis of complications.
OBJETIVOS: El objetivo de este estudio es analizar si los pacientes intervenidos de atresia de esófago (AE) se benefician de un programa de seguimiento multidisciplinar, basado en las guías clínicas actuales, implantado en nuestro centro. MATERIAL Y METODOS: Estudio retrospectivo, observacional y analítico incluyendo los pacientes intervenidos de AE entre 2012 y 2022. Se analizaron los resultados de la implantación en 2018 de un programa de consultas conjuntas de gastroenterología y cirugía pediátrica aplicando un protocolo basado en las nuevas guías ESPGHAN-NASPGHAN. Se dividieron a los pacientes tratados antes y después de 2018 y se compararon las variables cuantitativas: pérdidas de seguimiento, inicio y duración del tratamiento antirreflujo e inicio de nutrición enteral, y cualitativas: prevalencia de reflujo gastroesfoágico, realización de cirugía antirreflujo, infecciones respiratorias, estenosis de la anastomosis, refistulizaciones, disfagia, episodios de impactación, necesidad de gastrostomía y resultados de las endoscopias. RESULTADOS: Se incluyeron 38 pacientes. Un 63,2% presentaron reflujo gastroesofágico. El 97,4% tomaron tratamiento antirreflujo el primer año de vida que posteriormente se retiró en el 47,4%. El tiempo de retirada se redujo una media de 24 meses tras la aplicación del programa (p< 0,05). Se realizaron 4,6 veces más pHmetrías tras la implantación del programa. El protocolo estandarizó la realización de endoscopias en pacientes asintomáticos al cumplir 5 y 10 años. Se realizaron 25 endoscopias con tomas de biopsia después de 2018, detectando alteraciones histológicas en un 28%. El número de pérdidas de seguimiento se redujo de forma significativa tras la implantación del protocolo (p< 0,05). CONCLUSIONES: El seguimiento multidisciplinar digestivo-quirúrgico de los pacientes con AE genera un impacto positivo en su evolución. La aplicación de las guías facilita la optimización del tratamiento y el diagnóstico precoz de las complicaciones.

Introducción En el año 2020, en España, se diagnosticaron 282.421 nuevos casos de cáncer, encontrándose las neoplasias urológicas (NU) entre las más frecuentes. El tratamiento del cáncer en personas mayores es todo un reto, debido a su fragilidad y comorbilidades. Para responder a las necesidades que plantean las NU en las personas mayores, es necesaria una adecuada planificación de la enfermedad, comenzando por analizar los registros de cáncer. El objetivo fue, considerando a la población española de más de 65 años, proporcionar un análisis detallado de incidencia y mortalidad de las NU en el año 2020, así como las estimaciones para el año 2040. Material y métodos Las NU que se incluyeron fueron: testículo, vejiga, pene, riñón y próstata. Las estimaciones de incidencia y mortalidad fueron obtenidas de la base de datos GLOBOCAN. Resultados En el año 2020 se diagnosticaron en España 63.278 NU. Exceptuando la neoplasia de testículo, todas las neoplasias se diagnosticaron con mucha mayor frecuencia en el grupo de mayores de 65 años. Para el año 2040 se estima un aumento del 41,5%, alcanzando los 89.507 nuevos casos por año, de los cuales aproximadamente tres cuartas partes tendrán lugar en mayores de 65. El número de fallecidos mayores de 65 aumentará un 60,15% en 2040. Conclusión En las próximas 2 décadas es esperable que los nuevos casos de NU en mayores de 65 años aumenten por encima del 50%. Mayores recursos económicos y humanos, además de equipos multidisciplinares con experiencia y formación geriátrica, serán necesarios (AU)
Introduction In 2020, 282,421 new cases of cancer were diagnosed in Spain, and urological neoplasms (UN) were among the most frequent ones. Cancer treatment in elderly people is challenging due to frailty and comorbidities. Healthcare resources must be optimized in order to meet the needs of treating UN in the elderly, and deep analysis of cancer registries becomes mandatory. The objective of this work was to provide a detailed analysis of the incidence and mortality of UN in patients over 65 years old in the last year 2020 in Spain, as well as the estimates for the year 2040. Material and methods Incidence and mortality estimates were obtained from the GLOBOCAN database. The UN included were testicle, bladder, penis, kidney, and prostate. Results In 2020, 63,278 cases of UN were diagnosed in Spain. Most UN were much more frequent among patients > 65 years old, except for testicular cancers. For the year 2040, an increased incidence of 41.5% is estimated, reaching 89,507 new cases of UN per year, with approximately 3 out of 4 patients over 65 years of age. Deaths in people over 65 will increase by 60.15% in 2040. Conclusion In the next two decades, it is expected that new cases of UN in people over 65 years will rise above 50%. More financial and human resources, as well as multidisciplinary teams with experience and geriatric training, will be necessary (AU)

OBJECTIVE: To analyze the characteristics and variables associated with prolonged noninvasive ventilation performed completely in Emergency Departments (NIV-ED) and its influence upon effectiveness. DESIGN: A prospective, multicenter, observational multipurpose cohort study was carried out. SETTING: VNICAT Registry. SUBJECTS: Patients in which NIV-ED was performed in 11 Catalan hospitals in the months of February or March 2015. INTERVENTION: No. VARIABLES: The study variable was NIV-ED, which as a function of time was defined as prolonged or not prolonged. The efficacy variable was the success of the technique in terms of patient improvement. RESULTS: A total of 125 patients were included, with a median NIV-ED duration of 12 h, which was the cut-off point for the comparator groups. In 60 cases (48%) NIV-ED was not prolonged (<12 h), while in 65 cases (52%) ventilation was prolonged (≥12 h). Non-prolonged NIV-ED was associated to the indication of acute heart failure and prolonged ventilation to the presence of diabetes. There were no differences between non-prolonged and prolonged NIV-ED in terms of efficacy, and the success rate in terms of improvement was 68.3% and 76.9%, respectively, with an adjusted odds ratio of 1.49 (95%CI 0.61-3.60). CONCLUSIONS: Prolonged NIV-ED is a frequent situation, but few variables associated to it have been studied. The presence of prolonged ventilation did not influence the success rate of NIV.

INTRODUCTION: Congenital paraesophageal hernia (CPH) is a rare pathology in pediatric patients. Clinical signs may occur as early as in newborns, which means it requires early surgical repair. CLINICAL CASES: This is a series of three patients under 1 year of age diagnosed with type IV CPH - with symptoms occurring since they were newborns - who underwent laparoscopic surgical repair. One patient had been diagnosed prenatally. Age at surgery was 6 days, 36 days, and 9 months, respectively. Weight at surgery was 3.60 kg, 3.79 kg, and 8.20 kg, respectively. The patients underwent laparoscopy, with removal of the hernia sac, closure of the diaphragmatic pillars, placement of a reinforcement absorbable mesh, and Nissen fundoplication. Mean operating time was 130 minutes. No intraoperative complications were recorded. One patient developed a sliding hernia, which was subsequently repaired without complications. Mean follow-up time was 24 months.

OBJECTIVE: Even though thyroid surgery is rare in pediatric patients, frequency has increased in the last years. The objective of this study was to analyze the causes and results of these procedures in a pediatric surgical facility. PATIENTS AND METHODS: Retrospective study including all patients requiring thyroid surgery in our department from 2000 to 2019. Demographic data, diagnostic data, associated pathology, type of surgical procedure, pathological results, and intraoperative and postoperative complications were recorded. RESULTS: 47 patients with a mean age of 8.9 ± 3.9 years at surgery were included. The most frequent diagnosis was MEN syndrome (n = 30, 29 MEN 2A and 1 MEN 2B), followed by thyroid papillary carcinoma (n = 5), follicular adenoma (n = 5), multinodular goiter (n = 4), follicular carcinoma (n = 1), thyroglossal duct papillary carcinoma (n = 1), and Graves-Basedow syndrome (n = 1). 38 total thyroidectomies (73.7% of which were prophylactic), 3 double hemithyroidectomies, 5 hemithyroidectomies, and 5 lymphadenectomies were performed. No intraoperative complications or recurrent laryngeal nerve lesions were noted. Mean postoperative hospital stay was 1.3 ± 0.6 days. 7 patients had transitory asymptomatic hypoparathyroidism, and 1 patient had persistent symptomatic hypoparathyroidism. Pathological results of prophylactic thyroidectomies were: 18 C cell hyperplasias, 7 microcarcinomas, and 3 cases without histopathological disorders. CONCLUSIONS: Thyroid surgery in pediatric patients is safe if performed by specialized personnel. Even though it remains rare, frequency has increased in the last years.

The magnetic properties of [Formula: see text], a paradigmatic hexaferrite for permanent magnet applications, have been addressed in detail combining density functional theory including spin-orbit coupling and a Hubbard U term with Monte Carlo simulations. This multiscale approach allows to estimate the Néel temperature of the material from ab initio exchange constants, and to determine the influence of different computational conditions on the magnetic properties by direct comparison versus available experimental data. It is found that the dominant influence arises from the choice of the Hubbard U term, with a value in the 2-3 eV range as the most adequate to quantitatively reproduce the two most relevant magnetic properties of this material, namely: its large perpendicular magnetocrystalline anisotropy and its elevated Néel temperature.

OBJECTIVE: The prevalence of premenstrual discomfort among Spanish women is very high, and has a negative impact on their quality of life. By adopting the biopsychosocial approach, this study aims to understand women's experiences and insights, delve further into their beliefs and attitudes towards premenstrual syndrome and menstrual suppression, and to identify their proposals in order to adapt healthcare professionals' response to their needs and demands. METHODS: A qualitative study was conducted based on individual in-depth interviews with 16 women located in the Granada region. Purposive sampling was made using theoretical profiles. Informed consent was given. The study included data assessment, investigator triangulation, and a literature review. RESULTS: Premenstrual discomfort has an impact on physical and psychological health, disrupting daily lives and resulting in self-medication. Healthcare is considered deficient, since remedies are limited to medicalisation, but the source of the discomfort is not investigated. Different beliefs about the premenstrual syndrome (PMS) were found: PMS is inherent to menstrual cycle and cannot be avoided; PMS is the result of endogenous factors (such as genetics, defects or biochemical and hormonal disorders); exogenous factors (such as stress, eating habits, or exercise); the science and industry describe and treat PMS as a disease. Menstrual suppression is considered an option by women with children, though there is reticence due to the side effects found. Health education programmes for women are proposed, as well as the appropriate training for health professionals in order to overcome the pharmacological approach. CONCLUSIONS: The biopsychosocial approach helps to determine the perspective of the women, their needs and expectations in order to provide better healthcare services to premenstrual discomfort patients.

OBJECTIVE: To analyze bronchoalveolar lavage diagnostic effectiveness and impact on therapeutic management in pediatric patients. MATERIAL AND METHODS: Retrospective study of patients undergoing bronchoalveolar lavage at the pediatric surgery department from 2009 to 2019. The sample was divided into two groups: hemato-oncological patients and non-hemato-oncological patients. Demographic variables, bronchoalveolar lavage result, and subsequent therapeutic attitude were collected. RESULTS: 45 bronchoalveolar lavages were carried out in 38 patients. The hemato-oncological group consisted of 25 bronchoalveolar lavages. Patient mean age was 9.99 ± 2.34 years. 80% of patients had received anti-infective treatment prior to bronchoalveolar lavage. Bronchoalveolar lavage culture was positive in 52% of cases. Bronchoalveolar lavage results translated into therapeutic management change in 24% of cases (6/25). 3 postoperative complications were recorded, all mild. In the non-hemato-oncological group (n = 20), mean age was 6.70 ± 5.17 years. Bronchoalveolar lavage was positive in 25% of cases, and translated into management change in 5% of patients. Complication rate in this group was 30%. 2 patients required mechanical ventilation. CONCLUSIONS: According to our results, bronchoalveolar lavage in hemato-oncological patients helps achieve microbiological diagnosis in infectious respiratory conditions and is relatively well-tolerated. In non-hemato-oncological patients, diagnostic and therapeutic usefulness is low, and complication rate is not negligible. The risk-benefit balance should be individually considered in each patient.
OBJETIVO: Analizar la eficacia diagnóstica del lavado broncoalveolar y su impacto en el manejo terapéutico en pacientes pediátricos. MATERIAL Y METODOS: Estudio retrospectivo incluyendo a los pacientes a los que se les realizó un lavado broncoalveolar por parte del Servicio de Cirugía Pediátrica entre 2009 y 2019. Se ha dividido la muestra en dos grupos: pacientes hemato-oncológicos y no hemato-oncológicos. Se han recogido variables demográficas, el resultado del lavado broncoalveolar y la actitud terapéutica posterior. RESULTADOS: Se realizaron 45 lavados broncoalveolares en 38 pacientes. El grupo hemato-oncológico constaba de 25 lavados broncoalveolares. Los pacientes tenían una edad media de 9,99 ± 2,34 años. El 80% de los pacientes tenían tratamiento antiinfeccioso previo al lavado broncoalveolar. El cultivo del lavado broncoalveolar fue positivo en el 52% de los casos. El resultado del lavado broncoalveolar influyó en un cambio de manejo terapéutico en un 24% (6/25). Se produjeron 3 complicaciones postoperatorias, todas leves. En el grupo no hemato-oncológico (n = 20) la edad media era de 6,70 ± 5,17 años. El lavado broncoalveolar fue positivo en el 25% y supuso un cambio de manejo en un 5% de los pacientes. Este grupo tuvo una tasa de complicación del 30%, 2 pacientes requirieron ventilación mecánica. CONCLUSIONES: Según nuestros resultados, el lavado broncoalveolar en los pacientes hemato-oncológicos ayuda al diagnóstico microbiológico en procesos respiratorios infecciosos y es relativamente bien tolerado. En los no hemato-oncológicos, tiene una baja rentabilidad diagnóstico-terapéutica con una tasa de complicaciones no desdeñable. Sería necesario individualizar el balance beneficio-riesgo en cada paciente.

OBJECTIVE: To analyze bronchoalveolar lavage diagnostic effectiveness and impact on therapeutic management in pediatric patients. MATERIALS AND METHODS: Retrospective study of patients undergoing bronchoalveolar lavage at the pediatric surgery department from 2009 to 2019. The sample was divided into two groups: hemato-oncological patients and non-hemato-oncological patients. Demographic variables, bronchoalveolar lavage result, and subsequent therapeutic attitude were collected. RESULTS: 45 bronchoalveolar lavages were carried out in 38 patients. The hemato-oncological group consisted of 25 bronchoalveolar lavages. Patient mean age was 9.99 ± 2.34 years. 80% of patients had received anti-infective treatment prior to bronchoalveolar lavage. Bronchoalveolar lavage culture was positive in 52% of cases. Bronchoalveolar lavage results translated into therapeutic management change in 24% of cases (6/25). 3 postoperative complications were recorded, all mild. In the non-hemato-oncological group (n = 20), mean age was 6.70 ± 5.17 years. Bronchoalveolar lavage was positive in 25% of cases, and translated into management change in 5% of patients. Complication rate in this group was 30%. 2 patients required mechanical ventilation. CONCLUSIONS: According to our results, bronchoalveolar lavage in hemato-oncological patients helps achieve microbiological diagnosis in infectious respiratory conditions and is relatively well-tolerated. In non-hemato-oncological patients, diagnostic and therapeutic usefulness is low, and complication rate is not negligible. The risk-benefit balance should be individually considered in each patient

INTRODUCTION: Anastomotic stricture is the most common complication following esophageal atresia (EA) surgical repair. The objective of this study was to evaluate Anastomotic Stricture Index (ASI: relationship between pouch and stricture diameters in the postoperative esophagram) as a predictor of the need for esophageal dilatation. METHODS: A retrospective review of all patients undergoing EA repair in our healthcare facility from 2009 to 2017 was designed. Proximal pouch ASI (proximal ASI) and distal pouch ASI (distal ASI) in the first and second postoperative esophagram were calculated, and correlation with the number of esophageal dilatations required was studied. For statistical analysis purposes, Spearman's correlation test and ROC curves were used. RESULTS: Of the 31 patients included, 21 (67.7%) required esophageal dilatation, and 11 (35.5%) required 3 or more dilatations. The relationship between ASIs in the first esophagram and the need for esophageal dilatation was not statistically significant (p >0.05). The relationship between proximal ASI (RHO = 0.84, p <0.05) and the number of dilatations in the second esophagram was statistically significant. None of the patients with <0.55 proximal ASI required dilatation; patients with 0.55-0.79 proximal ASI required less than 3 dilatations; and patients with >0.79 proximal ASI had a high risk of requiring 3 or more dilatations. CONCLUSION: According to our study, measuring ASI in the second esophagram proves useful in predicting EA patients' postoperative management, especially when it comes to identifying patients with lower risk of undergoing multiple dilatations.
INTRODUCCION: La estenosis esofágica es la complicación más frecuente tras la corrección de la atresia esofágica (AE). El objetivo de este estudio es el análisis de los Índices de estenosis de la anastomosis (IEA: relación entre los diámetros de los bolsones y de la estenosis en el esofagograma postoperatorio) como predictores de la necesidad de dilatación esofágica. METODOS: Se diseña un estudio retrospectivo incluyendo los pacientes con AE y anastomosis esofágica en nuestro centro entre 2009-2017, calculando los IEA del bolsón proximal (IEA-proximal) y distal (IEA-distal) en el primer y segundo esofagograma postoperatorio, analizando su correlación con el número de dilataciones esofágicas que necesitaron. Para el análisis estadístico, se ha empleado el test de correlación de Spearman y las curvas ROC. RESULTADOS: Se incluyeron 31 pacientes: 21 precisaron dilatación esofágica (67%), y 11 de ellos (35%) 3 o más dilataciones. No se demostró relación estadísticamente significativa entre los IEA del primer esofagograma con la necesidad de dilatación esofágica (p >0,05). Se observó una relación entre el IEA-proximal (rho = 0,84, p <0,05) y el número de dilataciones en el segundo esofagograma. Ningún paciente con ASI-proximal <0,55 necesitó dilatación; los pacientes con ASI-proximal entre 0,55-0,79 precisaron menos de 3 dilataciones y los pacientes con ASI-proximal >0,79 presentaron alto riesgo de necesitar 3 o más dilataciones. CONCLUSION: Según los resultados de nuestro estudio, la medición de IEA en el segundo esofagograma constituye una herramienta útil para predecir el manejo postoperatorio en pacientes con AE, especialmente en la identificación de aquellos con menor riesgo de someterse a múltiples dilataciones.

A review of the present status, recent enhancements, and applicability of the Siesta program is presented. Since its debut in the mid-1990s, Siesta's flexibility, efficiency, and free distribution have given advanced materials simulation capabilities to many groups worldwide. The core methodological scheme of Siesta combines finite-support pseudo-atomic orbitals as basis sets, norm-conserving pseudopotentials, and a real-space grid for the representation of charge density and potentials and the computation of their associated matrix elements. Here, we describe the more recent implementations on top of that core scheme, which include full spin-orbit interaction, non-repeated and multiple-contact ballistic electron transport, density functional theory (DFT)+U and hybrid functionals, time-dependent DFT, novel reduced-scaling solvers, density-functional perturbation theory, efficient van der Waals non-local density functionals, and enhanced molecular-dynamics options. In addition, a substantial effort has been made in enhancing interoperability and interfacing with other codes and utilities, such as wannier90 and the second-principles modeling it can be used for, an AiiDA plugin for workflow automatization, interface to Lua for steering Siesta runs, and various post-processing utilities. Siesta has also been engaged in the Electronic Structure Library effort from its inception, which has allowed the sharing of various low-level libraries, as well as data standards and support for them, particularly the PSeudopotential Markup Language definition and library for transferable pseudopotentials, and the interface to the ELectronic Structure Infrastructure library of solvers. Code sharing is made easier by the new open-source licensing model of the program. This review also presents examples of application of the capabilities of the code, as well as a view of on-going and future developments.
