Multimorbidity as a predictor of health service utilization in primary care: a registry-based study of the Catalan population

Background: Multimorbidity is highly relevant for both service commissioning and clinical decision-making. Optimization of variables assessing multimorbidity in order to enhance chronic care management is an unmet need. To this end, we have explored the contribution of multimorbidity to predict use of healthcare resources at community level by comparing the predictive power of four different multimorbidity measures. Methods: A population health study including all citizens ≥18 years (n = 6,102,595) living in Catalonia (ES) on 31 December 2014 was done using registry data. Primary care service utilization during 2015 was evaluated through four outcome variables: A) Frequent attendants, B) Home care users, C) Social worker users, and, D) Polypharmacy. Prediction of the four outcome variables (A to D) was carried out with and without multimorbidity assessment. We compared the contributions to model fitting of the following multimorbidity measures: i) Charlson index; ii) Number of chronic diseases; iii) Clinical Risk Groups (CRG); and iv) Adjusted Morbidity Groups (GMA). Results: The discrimination of the models (AUC) increased by including multimorbidity as covariate into the models, namely: A) Frequent attendants (0.771 vs 0.853), B) Home care users (0.862 vs 0.890), C) Social worker users (0.809 vs 0.872), and, D) Polypharmacy (0.835 vs 0.912). GMA showed the highest predictive power for all outcomes except for polypharmacy where it was slightly below than CRG. Conclusions: We confirmed that multimorbidity assessment enhanced prediction of use of healthcare resources at community level. The Catalan population-based risk assessment tool based on GMA presented the best combination of predictive power and applicability

Esofagitis eosinofílica, eficacia de las alternativas terapéuticas en el adulto: revisión sistemática

Fundamentos: La esofagitis eosinofílica es hoy en día la principal causa de disfagia en el adulto. La elección de la terapia se debe consensuar con el paciente. El objetivo de este trabajo fue revisar la bibliografía científica para conocer la eficacia de las distintas opciones terapéuticas de la esofagitis eosinofílica en el adulto. Métodos: Se realizó una búsqueda de artículos durante el mes de febrero de 2023 en las bases de datos de PubMed, Web of Science, Scopus y Scielo, empleando los términos de búsqueda eosinophilic esophagitis, therapeutics y treatment, seleccionándose los ensayos clínicos y estudios observacionales publicados en los últimos diez años en adultos. Resultados: Se obtuvieron un total de 1.138 artículos, de los cuales 41 fueron seleccionados tras aplicar los criterios de elegibilidad. De las terapias disponibles, el tratamiento más frecuentemente analizado fueron los corticoides deglutidos, seguido de las dietas de eliminación y de los inhibidores de la bomba de protones, predominando los ensayos clínicos. Los estudios arrojan resultados sobre la eficacia de estas terapias en la remisión histológica y clínica, tanto en la inducción como a largo plazo. Conclusiones: Existen fundamentalmente tres terapias en la esofagitis eosinofílica en el adulto, siendo todas superiores frente a placebo en respuesta histológica y clínica

Efectos adversos inmunomediados gastrointestinales y hepáticos inducidos por los inhibidores del punto de control inmunitario: estudio descriptivo observacional

Introducción Los inhibidores del punto de control inmunitario (immune checkpoint inhibitors [ICI]) son fármacos eficaces en el tratamiento de diversas neoplasias. Sin embargo, se han relacionado con eventos adversos inmunomediados (EAI) gastrointestinales y hepáticos que pueden desencadenar su interrupción temporal o definitiva. Objetivo Evaluar, en condiciones de práctica real, la eficacia y la toxicidad gastrointestinal y hepática de los ICI en tratamientos oncológicos. Material y métodos Estudio retrospectivo con inclusión de pacientes con diagnóstico de neoplasia avanzada que habían recibido al menos una dosis de ICI entre mayo de 2015 y septiembre de 2018. Resultados Se incluyeron 132 pacientes con neoplasia de pulmón no microcítico (65, 15%, n = 86), melanoma (22, 7%, n = 30), carcinoma renal (9, 09%, n = 12) y otros tumores (3%, n = 4). Los fármacos empleados fueron nivolumab (n = 82), pembrolizumab (n = 28), atezolizumab (n = 13), durvalumab (n = 2), ipilimumab (n = 1) y la combinación anti-CTLA-4/PD-1 (n = 6). El 38, 6% (n = 51) desarrollaron EAI, de tipo gastrointestinal en el 12, 9% (n = 17). De ellos, el 47% (n = 8) requirieron esteroides, y un paciente precisó cirugía por perforación intestinal. En el 3, 03% (n = 4) se objetivaron EAI hepáticos grado I: el 50% (n = 2) requirieron corticoterapia y en un paciente fue preciso interrumpir el tratamiento. Entre los pacientes con tratamiento combinado, el 66, 6% (n = 4) presentaron EAI gastrointestinales. La incidencia de EAI no se relacionó con la edad, ni con el sexo, ni con la respuesta al fármaco empleado. Conclusiones Los EAI gastrointestinales figuran entre los más frecuentemente observados en pacientes en tratamiento con ICI. El manejo multidisciplinar y un mayor conocimiento de dichos eventos podrían ayudarnos a reducir su morbilidad, así como las interrupciones del tratamiento. Introduction Immune checkpoint inhibitors (ICIs) are effective agents against several malignancies. However, they are associated with gastrointestinal and liver immune-related adverse events (GI-IrAEs and LI-IrAEs), which can lead to their temporary or permanent discontinuation. Aim The aim of this study was to evaluate the efficacy and gastrointestinal and liver toxicity of ICIs in oncological treatments in actual clinical practice. Material and methods Patients with advanced cancer who received at least 1 ICI dose between May 2015 and September 2018 were retrospectively assessed. Results 132 patients with non-small cell lung cancer (65.15%, n = 86); melanoma (22.7%, n = 30); renal carcinoma (9.09%, n = 12); and other tumours (3%, n = 4) were included. The treatments administered were nivolumab (n = 82), pembrolizumab (n = 28), atezolizumab (n = 13), durvalumab (n = 2), ipilimumab (n = 1) and the antiCTLA-4/PD-1 combination (n = 6). In total, 51 patients (38.6%) developed IrAEs, 17 (12.9%) of which experienced GI-IrAEs. Of these, 8 (47%) needed steroids and 1 patient required surgery due to intestinal perforation. Grade I Li-IrAEs were observed in 4 patients (3.03%): 2 (50%) required corticosteroids and 1 patient had to discontinue treatment. Four patients (66.6%) who received combination therapy experienced GI-IrAEs. IrAE incidence were not associated with age, gender or drug response. Conclusions GI-IrAEs are one of the most common adverse events in patients receiving ICIs. A multidisciplinary approach and a greater understanding of these events could help to reduce morbidity and therapy discontinuation

Modular classes of skew algebroid relations

Skew algebroid is a natural generalization of the concept of Lie algebroid. In this paper, for a skew algebroid E, its modular class mod(E) is defined in the classical as well as in the supergeometric formulation. It is proved that there is a homogeneous nowhere-vanishing 1-density on E* which is invariant with respect to all Hamiltonian vector fields if and only if E is modular, i.e. mod(E)=0. Further, relative modular class of a subalgebroid is introduced and studied together with its application to holonomy, as well as modular class of a skew algebroid relation. These notions provide, in particular, a unified approach to the concepts of a modular class of a Lie algebroid morphism and that of a Poisson map.Comment: 20 page

SARS-CoV-2 infection induces a dual response in liver function tests: Association with mortality during hospitalization

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is associated with abnormal liver function tests. We hypothesized that early altered liver biochemistries at admission might have different clinical relevance than subsequent changes during hospitalization. A single-center retrospective study was conducted on 540 consecutive hospitalized patients, PCR-diagnosed with SARS-CoV-2. Liver test abnormalities were defined as the elevation of either gamma-glutamyltransferase (GGT), alanine aminotransferase (ALT), or aspartate aminotransferase (AST), above the upper limit of normality set by our laboratory. Linear mixed models (LMM) evaluated longitudinal associations, incorporating all available follow-up laboratory chemistries. By the end of the follow-up period, 502 patients (94.5%) were discharged (109 (20.5%) died). A total of 319 (64.3%) had at least one abnormal liver test result at admission. More prevalent were elevated AST (40.9%) and GGT (47.3%). Abnormalities were not associated with survival but with respiratory complications at admission. Conversely, LMM models adjusted for age and sex showed that longitudinal increases during hospitalization in ferritin, GGT, and alkaline phosphatase (ALP), as well as a decreased albumin levels, were associated with reduced survival. This dual pattern of liver damage might reconcile previous conflicting reports. GGT and ALP trajectories could be useful to determine who might need more surveillance and intensive care

Supercoherent States, Super K\"ahler Geometry and Geometric Quantization

Generalized coherent states provide a means of connecting square integrable representations of a semi-simple Lie group with the symplectic geometry of some of its homogeneous spaces. In the first part of the present work this point of view is extended to the supersymmetric context, through the study of the OSp(2/2) coherent states. These are explicitly constructed starting from the known abstract typical and atypical representations of osp(2/2). Their underlying geometries turn out to be those of supersymplectic OSp(2/2) homogeneous spaces. Moment maps identifying the latter with coadjoint orbits of OSp(2/2) are exhibited via Berezin's symbols. When considered within Rothstein's general paradigm, these results lead to a natural general definition of a super K\"ahler supermanifold, the supergeometry of which is determined in terms of the usual geometry of holomorphic Hermitian vector bundles over K\"ahler manifolds. In particular, the supergeometry of the above orbits is interpreted in terms of the geometry of Einstein-Hermitian vector bundles. In the second part, an extension of the full geometric quantization procedure is applied to the same coadjoint orbits. Thanks to the super K\"ahler character of the latter, this procedure leads to explicit super unitary irreducible representations of OSp(2/2) in super Hilbert spaces of $L^2$ superholomorphic sections of prequantum bundles of the Kostant type. This work lays the foundations of a program aimed at classifying Lie supergroups' coadjoint orbits and their associated irreducible representations, ultimately leading to harmonic superanalysis. For this purpose a set of consistent conventions is exhibited.Comment: 53 pages, AMS-LaTeX (or LaTeX+AMSfonts

Evaluation of integrated care services in Catalonia: population-based and service-based real-life deployment protocols

Background: Comprehensive assessment of integrated care deployment constitutes a major challenge to ensure quality, sustainability and transferability of both healthcare policies and services in the transition toward a coordinated service delivery scenario. To this end, the manuscript articulates four different protocols aiming at assessing large-scale implementation of integrated care, which are being developed within the umbrella of the regional project Nextcare (2016–2019), undertaken to foster innovation in technologically-supported services for chronic multimorbid patients in Catalonia (ES) (7.5 M inhabitants). Whereas one of the assessment protocols is designed to evaluate population-based deployment of care coordination at regional level during the period 2011–2017, the other three are service-based protocols addressing: i) Home hospitalization; ii) Prehabilitation for major surgery; and, iii) Community-based interventions for frail elderly chronic patients. All three services have demonstrated efficacy and potential for health value generation. They reflect different implementation maturity levels. While full coverage of the entire urban health district of Barcelona-Esquerra (520 k inhabitants) is the main aim of home hospitalization, demonstration of sustainability at Hospital Clinic of Barcelona constitutes the core goal of the prehabilitation service. Likewise, full coverage of integrated care services addressed to frail chronic patients is aimed at the city of Badalona (216 k inhabitants). Methods: The population-based analysis, as well as the three service-based protocols, follow observational and experimental study designs using a non-randomized intervention group (integrated care) compared with a control group (usual care) with a propensity score matching method. Evaluation of cost-effectiveness of the interventions using a Quadruple aim approach is a central outcome in all protocols. Moreover, multi-criteria decision analysis is explored as an innovative method for health delivery assessment. The following additional dimensions will also be addressed: i) Determinants of sustainability and scalability of the services; ii) Assessment of the technological support; iii) Enhanced health risk assessment; and, iv) Factors modulating service transferability. Discussion: The current study offers a unique opportunity to undertake a comprehensive assessment of integrated care fostering deployment of services at regional level. The study outcomes will contribute refining service workflows, improving health risk assessment and generating recommendations for service selection.publishedVersio
