ABSTRACT

OBJECTIVE: The aim of this review is to summarize the current evidence and future perspectives of bladder-sparing treatment for MIBC. METHODS: A non-systematic literature search in Medline/Pubmed was performed in October 2023 with the following keywords "bladder cancer", "bladder-sparing", "trimodal therapy", "chemoradiation", "biomarkers", "immunotherapy", "neoadjuvant chemotherapy", "radiotherapy". RESULTS: Urology guidelines recommend radical cystectomy as the standard curative treatment for muscle-invasive urothelial bladder cancer, reserving radiotherapy for patients who are unfit or who want to preserve their bladder. Given the morbidity and mortality of cystectomy and its impact on quality of life and bladder function, modern oncologic therapies are increasingly oriented toward organ preservation and maximizing functional outcomes while maintaining treatment efficacy. Trimodal therapy, which incorporates maximal transurethral resection followed by radiotherapy with concurrent radiosensitizing chemotherapy, is an effective regimen for bladder function preservation in well-selected patients. Despite the absence of comparative data from randomized trials, the two approaches seem to provide comparable oncologic outcomes. Studies are evaluating the expansion of eligibility criteria for trimodal therapy, the optimization of radiotherapy and immunotherapy delivery to further improve outcomes, and the validation of biomarkers to guide bladder preservation. CONCLUSIONS: Trimodal therapy has shown acceptable outcomes for bladder preservation; therefore, it provides a valid treatment option in well-selected patients.

ABSTRACT

A polyad-conserving algebraic model applied to vibrational excitations of asymmetric isotopologues of CO2 is presented. First, the problem of vibrational excitations is studied by taking into account only the minimum subspace of states to characterize the Fermi interaction. This analysis allows an estimation of the force constants as well as the feasibility of describing the system in a local mode scheme, in terms of SU(2) operators associated with Morse ladder operators for the stretches. This description together with the algebraic U(3) for the bends establishes the dynamical group SU1(2) × U(3) × SU2(2) for a series of isotopologues. Six isotopologues are considered, namely, 16O12C18O, 16O12C17O, 16O13C18O, 16O13C17O, 17O13C18O, and 17O12C18O in their electronic ground states. For isotopologues 16O12C18O, 16O12C17O, 17O12C18O, and 16O13C18O, the vibrational description was carried out using a Hamiltonian involving 14 parameters. For this series of isotopologues with a number of energy terms 90, 57, 42, and 40, the deviations obtained were rms = 0.15, 0.10, 0.06, and 0.07 cm-1, respectively. For 16O13C17O, with 28 experimental energies and involving 13 parameters, the deviation was rms = 0.05 cm-1, while for 17O13C18O, a different strategy was proposed since only 12 experimental energy levels. In all cases, the polyad scheme P212 = 2(ν1 + ν3) + ν2 was considered. In addition, a new criterion of locality/normality degree is proposed, embracing the case of molecules with normal mode behavior, in particular, the isotopologues of CO2.

ABSTRACT

INTRODUCTION: The Andalusian Registry of Pregnancies in patients with multiple sclerosis is the largest Spanish registry on multiple sclerosis (MS) and family planning. For the first time, it includes information on the fertility of men with MS. The influence of the use of a disease-modifying treatment (DMT) on the health of the foetus/newborn and the impact of breastfeeding on MS are also analysed. SUBJECTS AND METHODS: This is a multicentre, prospective and observational study. Recruitment of patients took place between December 2018 and December 2020. Women were followed up for one year after delivery. Altogether 100 women and 16 men were included, with a total of 103 newborn infants. RESULTS: The annualised relapse rate of the women with MS decreased significantly during pregnancy (from 0.23 to 0.065). A total of 11.2% of patients resorted to assisted reproductive techniques in order to conceive a child. No association was found between the use of a DMT at conception and/or pregnancy and the risk of miscarriage, prematurity or low birth weight. Over half the women with MS (54.2%) chose to breastfeed (26.7% of them while on a DMT). CONCLUSIONS: MS does not affect the fertility of men. Neither does the use of a DMT at the time of conception affect their fertility or their children's health. Assisted reproductive techniques did not have a negative impact on the course of MS. Breastfeeding is a common practice among women with MS and there is no evidence of positive or negative effects on disease progression.


TITLE: Planificación familiar en hombres y mujeres con esclerosis múltiple. Análisis del Registro Andaluz (2018-2022).Introducción. El Registro Andaluz de Embarazos en pacientes con esclerosis múltiple (EM) es el mayor registro español sobre EM y planificación familiar. Por primera vez se incluye información sobre la fertilidad de hombres con EM. También se analizan la influencia del uso de un tratamiento modificador de la enfermedad (TME) en la salud del feto o recién nacido y el impacto de la lactancia materna en la EM. Sujetos y métodos. Es un estudio observacional, prospectivo y multicéntrico. El reclutamiento de pacientes se hizo entre diciembre de 2018 y diciembre de 2020. El seguimiento de las mujeres tras el parto fue de un año. Se incluyó a 100 mujeres y 16 hombres, con un total de 103 recién nacidos. Resultados. La tasa anualizada de brotes de las mujeres con EM descendió durante el embarazo de forma significativa (de 0,23 a 0,065). Un 11,2% de los pacientes recurrieron a técnicas de reproducción asistida para conseguir la gestación. No se encontró relación entre el uso de un TME en la concepción y/o embarazo y el riesgo de aborto, prematuridad o bajo peso al nacer. El 54,2% de las mujeres con EM optaron por dar lactancia (el 26,7% de ellas usando un TME). Conclusiones. La EM no afecta a la fertilidad de los hombres. Tampoco influye en ésta, ni en la salud de sus hijos, el uso de un TME en el momento de la concepción. Las técnicas de reproducción asistida no impactaron negativamente en la evolución de la EM. La lactancia se impone como una práctica habitual entre las mujeres con EM y no se evidencian efectos positivos o negativos sobre la evolución de la enfermedad.

ABSTRACT

El síndrome de obesidad hipoventilación (SOH) se define como la coexistencia de obesidad (índice de masa corporal≥ 30 kg/mg²), alteraciones respiratorias durante el sueño e hipoventilación alveolar crónica que acarrea hipercapnia diurna(pCO2 ≥ 45 mmHg), cuando otras causas de hipoventilación han sido excluidas. Los pilares de tratamiento para el SOH sonla pérdida de peso y la presión positiva en la vía aérea (PAP) durante el sueño. El manejo de estos pacientes ha de sermultidisciplinario, con modificación de hábitos de vida, intensificación de la actividad física y estrategias de intervenciónfarmacológica o quirúrgica para la pérdida de peso, individualizando las terapias según cada paciente y sus comorbilidades.El modo de inicio de la PAP dependerá de la coexistencia de apnea obstructiva del sueño (AOS), considerando que apro-ximadamente el 90% de los pacientes con SOH presentan concomitantemente AOS, aunque de estos el 73% se consideraAOS grave. En aquellos pacientes con SOH y AOS grave en situación de estabilidad clínica se inclinará por inicio conpresión positiva continua en la vía aérea. Por otra parte, en aquellos pacientes sin AOS grave o durante una hospitalización,se recomienda iniciar directamente ventilación mecánica no invasiva. El seguimiento del paciente debe contemplar loscambios de estrategia necesarios para intentar un control óptimo del peso y el cumplimiento de la PAP.(AU)


Obesity hypoventilation syndrome (OHS) is defined as the coexistence of obesity (body mass index ≥ 30 kg/mg²), respiratorydisturbances during sleep and chronic alveolar hypoventilation leading to daytime hypercapnia (pCO2 ≥ 45 mmHg), whenother causes of hypoventilation have been excluded. The mainstays of treatment for OHS are weight loss and positive airwaypressure (PAP) during sleep. The management of these patients must be multidisciplinary, with modification of lifestyle habits,intensification of physical activity and pharmacological or surgical intervention strategies for weight loss, individualizing thera-pies according to each patient and their comorbidities. The mode of onset of PAP will depend on the coexistence of obstruc-tive sleep apnea (OSA), considering that approximately 90% of patients with OHS present concomitant OSA, although 73%of these are considered severe OSA. In those patients with OHS and severe OSA in a situation of clinical stability, it is recom-mended to start with continuous positive airway pressure. On the other hand, it is recommended to start non invasive mecha-nical ventilation directly for those patients without severe OSA or during hospitalization. The follow-up of the patient mustconsider the necessary changes in strategy to try to achieve optimal weight control and compliance with the PAP.(AU)

ABSTRACT

Introducción: Los anestésicos locales (AL) son fármacos ampliamente utilizados para procedimientos anestésicos por su perfil riesgo/beneficio favorable respecto a los anestésicos generales. No obstante, estos fármacos no están exentos de efectos adversos. Caso clínico: Hombre de 44 años sin antecedentes neurológicos que presenta un cuadro de toxicidad sistémica por AL tras la instilación de bupivacaína intratecal para ser intervenido de artroplastia de cadera. Conclusiones: Los cuadros de toxicidad sistémica por AL pueden producir sintomatología neurológica asociada o no a inestabilidad hemodinámica. Habitualmente, los síntomas neurológicos ocurren de forma precoz y deben alertar sobre la posible ocurrencia de eventos hemodinámicos ulteriores que pueden comprometer la vida del paciente. Conocer la existencia y el manejo clínico de estos cuadros de toxicidad resulta fundamental para mejorar la evolución y el pronóstico de este cuadro potencialmente mortal.(AU)


Introduction: Local anaesthetics (LA) are drugs that are widely used in anaesthetic procedures because of their favourable risk/benefit profile compared to general anaesthetics. Yet, these drugs also have some adverse effects. Case report: We report the case of a 44-year-old man with no neurological history who presented systemic toxicity due to LA after instillation of intrathecal bupivacaine for hip arthroplasty surgery. Conclusions: Systemic toxicity caused by LA can give rise to neurological symptoms that may or may not be associated with haemodynamic instability. Neurological symptoms usually occur early on and should alert to the possible occurrence of further life-threatening haemodynamic events. Being aware of the existence of these toxicities and their clinical management is essential to improve the evolution and prognosis of this potentially fatal condition.(AU)

ABSTRACT

This work aims to contribute to the debate on practical utilization of different location models for consolidation, redistribution, and repackaging centers in a supply chain to optimize shipments, thereby reducing food loss and waste, within the framework of quality of customer service improvement. The scenario in question is the creation of a redistribution center for highly perishable products (fruits and vegetables) from southeast Spain-the leading European supplier-for customers throughout Europe. It is estimated that 10% of exports (more than 530,000 metric tons) from this area are returned by customers due to minor defects. These products cannot be reused and are therefore wasted. Regarding the methodology, comparisons were made between the p-median, gravity p-median, and p-center models. Scenarios of change in demand and randomness in distances were also tested. In addition, the modelling used included the cost and time within a multicriteria optimization framework to assess the possibility of a transport mode change. It was observed, for example, that the gravity p-median model proved useful for perishable products and the logistics strategy chosen. Furthermore, the p-median model displayed strong robustness against long-term changes in demand and random distances. In general, it was demonstrated that this strategy would successfully reduce the response time and distance of shipment from the distribution center to the customers and thereby improve sustainability of the service, reducing the waste related to direct shipments. Furthermore, this research also demonstrated the difficulty of using intermodality in this context, mainly due to transit time, which would undoubtedly increase the waste generated.

ABSTRACT

Facing worldwide environmental and social concerns, manufacturing firms are trying to adopt effective environmentally friendly actions to mitigate their environmental impacts. Although the existent literature has provided many insights about the drivers of sustainable product innovation, little is known about the impact of firm growth. Thus, we intend to contribute to this gap in the literature by examining the impact that firm growth can have on sustainable product innovation. To achieve this goal, the partial least square (PLS) modeling technique was used to analyze a dataset of 3250 manufacturing firms from 39 different countries. The results reveal that firm growth exerts a positive effect on sustainable product innovation and that the relationship is partially mediated by the adoption of environmental practices. The findings also indicate that managerial barriers lessen the effectiveness of the adoption of environmental practices in facilitating the development of sustainable product innovation, while improving labor conditions increases it. However, operational barriers do not exert a significant moderating effect between the adoption of environmental practices and sustainable product innovation. These results prompt interesting insights related to theory development in environmental management and sustainable product innovation research.

ABSTRACT

ANTECEDENTES: La colangitis biliar primaria (CBP) es una enfermedad hepática inflamatoria crónica colestásica de causa desconocida. Varios patógenos virales y bacterianos han sido propuestos como factores que podrían gatillar una respuesta inmune por mimetismo molecular, o directamente estar relacionados en la persistencia del daño biliar. Existen reportes controversiales respecto al rol de en la patogenia de CBP. OBJETIVOS: Investigar marcadores de infección de séricos y en hígado de pacientes con CBP. PACIENTES Y MÉTODOS: Veinte pacientes diagnosticados con CBP y 20 pacientes control con otras enfermedades hepáticas crónicas no colestásicas fueron estudiados. Se determinaron anticuerpos séricos anti- (IgG). Se realizó detección inmunohistoquímica de antígenos de en hígado. Se extrajo DNA de hígado para amplificación de la secuencia específica de rRNA 16S de por PCR. Fueron usados controles de amplificación de DNA bacteriano y humano. Los pacientes firmaron consentimiento informado. Se realizó un metaanálisis de la diferencia de riesgo de CBP en pacientes infectados por y en un grupo control. RESULTADOS: Los anticuerpos séricos fueron positivos en 30% de los pacientes con CBP y 50% de los controles (p = NS). Antígenos de no fueron detectados en tejido hepático de pacientes con CBP ni de controles. No se amplificó ADN bacteriano en ninguna de las muestras. El metaanálisis de la diferencia de riesgo mostró gran heterogeneidad de los estudios, por lo que no se realizó una estimación de diferencia de riesgo agrupada. DISCUSIÓN: No encontramos asociación entre infección por y CBP. En la evidencia actual, un estudio presenta resultados a favor de la asociación entre y CBP y tres estudios resultados en contra.,


Primary biliary cholangitis (PBC) is a chronic cholestatic inflammatory liver disease of unknown cause. Several viral and bacterial pathogens have been proposed as factors that could either trigger an immune response by molecular mimicry or directly be involved in the persistence of biliary damage. There are conflicting reports respecting the role of in the pathogenesis of PBC. To investigate markers of infection in serum and liver tissue from patients with PBC. Twenty patients with diagnosis of PBC and 20 control patients with other non-cholestatic chronic liver diseases were studied. Serum anti- antibodies (IgG) were determined. Liver tissue was available for immunohistochemistry detection of antigens. DNA was extracted from liver tissue and a specific sequence of 16S rRNA gene was amplified by CPR. Adequate controls of bacterial and human DNA amplification were used. Informed consent was obtained from patients. A meta-analysis of risk difference of PBC in Chlamydophila pneumoniae infected patients and in the control groupwas performed. Serum antibodies were positive in 30% of patients with PBC and 50% of controls (p = NS). antigens were not detected in liver tissue neither of patients with PBC nor controls. Bacterial DNA did not amplify in any of the samples, despite good amplification of internal and external controls. Risk difference meta-analysis showed high heterogeneity between studies. Therefore, we did not estimate a pooled risk difference. Our results do not support the association between infection and PBC. In the current literature only one study shows an association between and PBC, but other three studies do not support it.

ABSTRACT

Here we report the IR spectra of FeEnterobactin in catecholate conformations ([CatFeEB]3-) obtained by DFT calculations using PBE/QZVP and their correlation it with its experimental counterpart [SalH3FeEB]0. Fragments of FeEnterobactin and Enterobactin (H6EB) are elucidated from their MALDI-TOF mass spectrometry, and the dependence of the frontier orbitals (HOMO and LUMO) with the catecholamide dihedral angles of H6EB is reported. The frequency distribution of catecholamide dihedral angle of H6EB was carried-out using molecular dynamics (MD). The data presented enriches the understanding of [CatFeEB]3 - and H6EB frequency distribution and reactivity.

ABSTRACT

Emerging and re-emerging epidemic diseases pose an ongoing threat to global health. Currently, Enterobactin and Enterobactin derivatives have gained interest, owing to their potential application in the pharmaceutical field. As it is known [J. Am. Chem. Soc (1979) 101, 20, 6097-6104], Enterobactin (H6EB) is an efficient iron carrier synthesized and secreted by many microbial species. In order to facilitate the elucidation of enterobactin and its analogues, here we propose the creation of a H6EB standard set using Density Functional Theory Infrared (IR) and NMR spectra. We used two exchange-correlation (xc) functionals (PBE including long-range corrections LC-PBE and mPW1), 2 basis sets (QZVP and 6-31G(d)) and 2 grids (fine and ultrafine) for most of the H6EB structures dependent of dihedral angles. The results show a significant difference between the OH and NH bands, while the CO amide and O(CO) IR bands are often found on top of each other. The NMR DFT calculations show a strong dependence on the xc functional, basis set, and grid used for the H6EB structure. Calculated 1H and 13C NMR spectra enable the effect of the solvent to be understood in the context of the experimental measurements. The good agreement between the experimental and the calculated spectra using LC-PBE/QZVP and ultrafine grid suggest the possibility of the systems reported here to be considered as a standard set. The dependence of electrostatic potential and frontier orbitals with the catecholamide dihedral angles of H6EB is described. The matrix-assisted laser desorption/ionization time of the flight mass spectrometry (MALDI-TOF MS) of H6EB is also reported of manner to enrich the knowledge about its reactivity.

ABSTRACT

Hepatocellular carcinoma (HCC) is the main primary liver malignancy. Its prevalence is increasing and is associated in 90% to cirrhotic patients. Hemoperitoneum secondary to spontaneous rupture of the tumor is an uncommon complication in Latin America and the Western world, being more prevalent in Asian races. However, it is associated to hemodynamic repercussion with high mortality, therefore high level of suspicion and early treatment are required. Regarding the management of the condition, in addition to hemodynamic stabilization, active hemostatic control is recommended over conservative management, transarterial chemoembolization being currently the chosen alternative. We present a series of three clinical cases of patients who debuted with clinical manifestation of hemoperitoneum during the diagnostic process of a HCC.


El carcinoma hepatocelular (CHC) corresponde a la principal neoplasia maligna primaria hepática. Su prevalencia va en aumento y se asocia en 90% a pacientes cirróticos. El hemoperitoneo secundario a rotura espontánea del tumor constituye una complicación infrecuente en Latinoamérica y Occidente, siendo más prevalente en razas asiáticas. Sin embargo, se asocia a repercusión hemodinámica con alta mortalidad, por lo que requiere un alto índice de sospecha y tratamiento oportuno precoz. En cuanto al manejo del cuadro, junto a la estabilización hemodinámica se recomienda un control hemostático activo por sobre manejo conservador, siendo la embolización transarterial la alternativa de elección actualmente. Describimos a continuación una serie de tres casos clínicos de pacientes que debutan con manifestación clínica de hemoperitoneo durante el proceso diagnóstico de un CHC.

ABSTRACT

BACKGROUND/OBJECTIVE: The objective of the study was to provide current estimates of the prevalence and trends of overweight and obesity (OW+OB) in Mexican children and adolescents. SUBJECTS/METHODS: Body mass index objectively measured was analyzed for 37 147 children and adolescents aged 0-19 years obtained in 2012 as part of the National Health and Nutrition Survey (ENSANUT-2012), a nationally representative sample of the Mexican population. In addition, data from previous National Nutrition Surveys obtained in 1988, 1999 and 2006 were compared with analyze trends over a 24-year period (1988-2012) for children <5 years of age and adolescents and over a 13-year period (1999-2012) for school-age children. World Health Organization Child Growth Standard was used to define OW+OB. RESULTS: In 2012, 33.5% of children <5 years of age (both sexes) were at risk of overweight or were overweight (OW); 32% and 36.9% of girls and boys 5-11 years of age were OW+OB, respectively, and 35.8% and 34.1% of female and male adolescents were OW+OB, respectively. Statistically significant trends were documented for all age groups during the study period. Overall change in the combined prevalence in preschool children was 6.3±1.0 percentage points (pp; P<0.001; 0.26 pp per year) in the last 24 years, showing the highest increase between 1988 and 1999, whereas for school-age girls (from 1999 to 2012) and adolescent females (from 1988 to 2012), OW+OB increased across all periods at a declining trend, with an overall change of 0.5 and 1.0 pp per year, respectively. Changes in the prevalence of OW+OB were highest among children and adolescents in the lowest quintile of the household living condition index. CONCLUSIONS: Prevalence of OW+OB among children and adolescents increased significantly during the last 13-24 years. The rate of increase has declined in the last 6 years in all age groups. Changes in prevalence of OW+OB presented here suggest that, in Mexico, the burden of obesity is shifting toward the groups with lower socioeconomic level.
