Social inequalities in multimorbidity patterns in Europe: A multilevel latent class analysis using the European Social Survey (ESS)

Multimorbidity is associated with lower quality of life, greater disability and higher use of health services and is one of the main challenges facing governments in Europe. There is a need to identify and characterize patterns of chronic conditions and analyse their association with social determinants not only from an individual point of view but also from a collective point of view. This paper aims to respond to this knowledge gap by detecting patterns of chronic conditions and their social determinants in 19 European countries from a multilevel perspective. We used data from the ESS round 7. The final sample consisted of 18,933 individuals over 18 years of age, and patterns of multimorbidity from 14 chronic conditions were detected through Multilevel Latent Class Analysis, which also allows detecting similarities between countries. Gender, Age, Housing Location, Income Level and Educational Level were used as individual covariates to determine possible associations with social inequalities. The goodness-of-fit indices derived in a model with six multimorbidity patterns and five countries clusters. The six patterns were "Back, Digestive and Headaches", "Allergies and Respiratory", "Complex Multi -morbidity", "Cancer and Cardiovascular", "Musculoskeletal" and "Cardiovascular"; the five clusters could be associated with some geographical areas or welfare states. Patterns showed significant differences in the cova-riates of interest, with differences in education and income being of particular interest. Some significant dif-ferences were found among patterns and the country groupings. Our findings show that chronic diseases tend to appear in a combined and interactive way, and socioeconomic differences in the occurrence of patterns are not only of the individual but also of group importance, emphasising how the welfare states in each country can influence in the health of their inhabitants

Effect of Fish Oil Parenteral Emulsion Supplementation on Inflammatory Parameters after Esophagectomy

(Background) Esophagectomy (EPG) presents high morbidity and mortality. Omega-3 fatty acids (omega-3FA) are a pharmaconutrient with benefits for postoperative morbidity. Studies of omega-3FA administered parenterally after esophagectomy are scarce. This study proposes to investigate the effect of combining fish oil lipid emulsions (LE) administered parenterally with enteral nutrition support. (Methods) Randomization was 1:1:1 in three groups: Group A received a LE mixture of 0.4 g/kg/day of fish oil and 0.4 g/kg/day of LCT/MCT 50:50, Group B received 0.8 g/kg/day of fish oil LE, and Group C received 0.8 g/kg/day of LCT/MCT 50:50. Variables were measured at recruitment time and day +1, +3, and +5. Inflammatory variables studied were Interlukin-6, C-reactive protein (CRP), tumoral necrosis factor-alpha (TNF-alpha), IL-10, IL-8 and CD25s. Safety, nutritional parameters and complications were analyzed. (Results) Administration of omega-3LE in the immediate postoperative period did not modulate the earlier inflammatory response. Statistically significant differences were found in IL-6 and CRP overall temporal evolution but were not found when studying the type of LE administered or in patients needing critical care. Administration of omega-3 resulted in safe and improved hypertriglyceridemia, depending on the dose. (Conclusions) omega-3FA has no impact on the early inflammatory postoperative response assessed for a short period but was safe. More studies for longer periods are needed

La WebQuest: una herramienta disponible en la Web 2.0 que permite renovar las prácticas docentes

La WebQuest corresponde a una herramienta didáctica sustentada en las corrientes constructivistas del aprendizaje, cuya característica central es el uso de Internet. Esta cualidad nos ha servido como antecedente para aprovechar sus ventajas e incorporarla en nuestra labor docente. No obstante, consideramos que antes de querer introducir cualquier recurso TIC en el aula, necesitamos tener un profundo conocimiento sobre cómo estos recursos pueden ser utilizados con un sentido didáctico. Por tal razón, hemos considerado necesario llevar a cabo este trabajo en etapas progresivas. La primera, focalizada hacia la apropiación de la WebQuest como herramienta didáctica, la definición de criterios comunes sobre el qué, el cómo y el para qué de su implementación. La segunda, orientada al diseño de WebQuest en base a parámetros de calidad y de acuerdo a la disciplina de cada docente que conforma esta Red, así como también la generación de espacios de reflexión y valoración de evaluación de las mismas. La tercera, focalizada en la aplicación directa de esta herramienta en nuestras clases y el seguimiento de sus resultados con fines investigativos. En esta comunicación se presenta el proceso llevado a cabo en la primera etapa

T cells isolated from G-CSF-treated multiple myeloma patients are suitable for the generation of BCMA-directed CAR-T cells

Autologous cell immunotherapy using B cell maturation antigen (BCMA)-targeted chimeric antigen receptor (CAR)-T cells is an effective novel treatment for multiple myeloma (MM). This therapy has only been used for relapsed and refractory patients, at which stage the endogenous T cells used to produce the CAR-T cells are affected by the immunosuppressive nature of advanced MM and/or side effects of previous therapies. An alternative pool of fitter T cells is found in leukocytoapheresis products that are routinely collected to obtain hematopoietic progenitor cells for autologous stem cell transplantation (ASCT) early in the treatment of MM. However, to mobilize the progenitor cells, patients are dosed with granulocyte colony-stimulating factor (G-CSF), which is reported to adversely affect T cell proliferation, function, and differentiation. Here, we aimed to first establish whether G-CSF treatment negatively influences T cell phenotype and to ascertain whether previous exposure of T cells to G-CSF is deleterious for anti-BCMA CAR-T cells. We observed that G-CSF had a minimal impact on T cell phenotype when added in vitro or administered to patients. Moreover, we found that CAR-T cell fitness and anti-tumor activity were unaffected when generated from G-CSF-exposed T cells. Overall, we showed that ASCT apheresis products are a suitable source of T cells for anti-BCMA CAR-T cell manufacture

Case report : Challenges in immune reconstitution following hematopoietic stem cell transplantation for CTLA-4 insufficiency-like primary immune regulatory disorders

Cytotoxic T-lymphocyte antigen-4 (CTLA-4) haploinsufficiency is a T-cell hyperactivation disorder that can manifest with both immunodeficiency and immune dysregulation. Approximately one-third of patients may present mild symptoms and remain stable under supportive care. The remaining patients may develop severe multiorgan autoimmunity requiring lifelong immunosuppressive treatment. Hematopoietic stem cell transplantation (HSCT) is potentially curable for patients with treatment-resistant immune dysregulation. Nevertheless, little experience is reported regarding the management of complications post-HSCT. We present case 1 (CTLA-4 haploinsufficiency) and case 2 (CTLA-4 insufficiency-like phenotype) manifesting with severe autoimmunity including cytopenia and involvement of the central nervous system (CNS), lung, and gut and variable impairment of humoral responses. Both patients underwent HSCT for which the main complications were persistent mixed chimerism, infections, and immune-mediated complications [graft-versus-host disease (GVHD) and nodular lung disease]. Detailed management and outcomes of therapeutic interventions post-HSCT are discussed. Concretely, post-HSCT abatacept and human leukocyte antigen (HLA)-matched sibling donor lymphocyte infusions may be used to increase T-cell donor chimerism with the aim of correcting the immune phenotype of CTLA-4 haploinsufficiency

Multimorbidity Patterns and Their Association with Social Determinants, Mental and Physical Health during the COVID-19 Pandemic

Background: The challenge posed by multimorbidity makes it necessary to look at new forms of prevention, a fact that has become heightened in the context of the pandemic. We designed a questionnaire to detect multimorbidity patterns in people over 50 and to associate these patterns with mental and physical health, COVID-19, and possible social inequalities. Methods: This was an observational study conducted through a telephone interview. The sample size was 1592 individuals with multimorbidity. We use Latent Class Analysis to detect patterns and SF-12 scale to measure mental and physical quality-of-life health. We introduced the two dimensions of health and other social determinants in a multinomial regression model. Results: We obtained a model with five patterns (entropy = 0.727): ‘Relative Healthy’, ‘Cardiometabolic’, ‘Musculoskeletal’, ‘Musculoskeletal and Mental’, and ‘Complex Multimorbidity’. We found some differences in mental and physical health among patterns and COVID-19 diagnoses, and some social determinants were significant in the multinomial regression. Conclusions: We identified that prevention requires the location of certain inequalities associated with the multimorbidity patterns and how physical and mental health have been affected not only by the patterns but also by COVID-19. These findings may be critical in future interventions by health services and governments17 página

Inflammatory processes involved in the alteration of liver function biomarkers in adult hospitalized patients treated with parenteral nutrition

IntroductionLiver damage has been associated with the accumulation of phytosterols (PS) in patients treated with parenteral nutrition (PN). We aimed to study the association of inflammatory markers with liver function biomarker (LFB) alterations in patients treated with PN containing PS.Materials and methodsProspective observational study. Simple linear and stepwise multiple linear regression tests and interactions were performed.ResultsNineteen patients were included. In the multivariable model, determinations based on LFBs as dependent and phytosterols (and their fractions) as independent variables showed an association between increases in gamma-glutamyltransferase (GGT) and lanosterol (p < 0.001), stigmasterol (p < 0.001), interleukin-10 (IL-10) × total phytosterols (Phyt) (p < 0.009), tumor necrosis factor-α (TNF-α) × Phyt (p < 0.002), IL-10 × sitosterol (p < 0.002), TNF-α × sitosterol (p < 0.001), IL-10 × campesterol (p < 0.033), IL-10 (p < 0.006 and p < 0.015), TNF-α (p < 0.048 and p < 0.027). Increases in alanine aminotransferase (ALT) were associated with Phyt (p < 0.006), lanosterol (p < 0.016), C-reactive protein (CRP) × campesterol (p < 0.001), interleukin-6 (IL-6) × stigmasterol (p < 0.030), CRP (p < 0.08), and IL-6 (p < 0.042). Alkaline phosphatase (AP) increases were associated with CRP (p < 0.002).DiscussionInflammation in the presence of plasmatic PS seems to have a synergistic effect in impairing liver function, mainly altering GGT but also ALT

La Webquest: una metodología apoyada en la red para renovar la docencia en Educación Superior

La WebQuest responde a una estrategia didáctica basada en la incorporación de las TIC en el aula, cuyo sustento teórico está en las corrientes constructivistas y el aprendizaje colaborativo, siendo de este modo pertinente a las directrices del EEES. En virtud de ello, nos hemos propuesto enfocar nuestras prácticas docentes aprovechando dicha estrategia didáctica y los recursos disponibles en la Web 2.0. Ahora bien, consideramos que como paso previo a la implementación de cualquier recurso TIC necesitamos tener un profundo conocimiento sobre el mismo. Es por ello que, para el desarrollo del trabajo, hemos considerado llevar a cabo un proceso gradual dividido en tres fases. La primera, centrada en la apropiación de la WebQuest como herramienta metodológica, la unificación de criterios y significados en torno al qué, al cómo y al para qué de su implementación. La segunda, focalizada en el diseño de WebQuest y la generación de espacios colaborativos de evaluación de las mismas. La tercera, enfatiza la aplicación directa de WebQuest en nuestras clases y el seguimiento de éstas con fines investigativos. En esta comunicación damos cuenta del proceso llevado a cabo en la primera fase, destacando la multidisciplinaridad que caracteriza al equipo de trabajo

Post-mortem neuropathologic examination of a 5-case series of CAR T-cell treated patients

Introduction: Chimeric antigen receptor (CAR) T-cell therapy is a promising immunotherapy for the treatment of refractory hematopoietic malignancies. Adverse events are common, and neurotoxicity is one of the most important. However, the physiopathology is unknown and neuropathologic information is scarce.Materials and methods: Post-mortem examination of 6 brains from patients that underwent CAR T-cell therapy from 2017 to 2022. In all cases, polymerase chain reaction (PCR) in paraffin blocks for the detection of CAR T cells was performed.Results: Two patients died of hematologic progression, while the others died of cytokine release syndrome, lung infection, encephalomyelitis, and acute liver failure. Two out of 6 presented neurological symptoms, one with extracranial malignancy progression and the other with encephalomyelitis. The neuropathology of the latter showed severe perivascular and interstitial lymphocytic infiltration, predominantly CD8+, together with a diffuse interstitial histiocytic infiltration, affecting mainly the spinal cord, midbrain, and hippocampus, and a diffuse gliosis of basal ganglia, hippocampus, and brainstem. Microbiological studies were negative for neurotropic viruses, and PCR failed to detect CAR T -cells. Another case without detectable neurological signs showed cortical and subcortical gliosis due to acute hypoxic-ischemic damage. The remaining 4 cases only showed a mild patchy gliosis and microglial activation, and CAR T cells were detected by PCR only in one of them.Conclusions: In this series of patients that died after CAR T-cell therapy, we predominantly found non-specific or minimal neuropathological changes. CAR T-cell related toxicity may not be the only cause of neurological symptoms, and the autopsy could detect additional pathological findings
