Oportunidades de inclusión en el deporte. Estudio de caso de un deportista con parálisis cerebral

This paper studies the case of Maikel, an athlete with cerebral palsy (CP) who practices sports in an inclusive and specific or segregated environment. Using qualitative methodology, the aim is to identify the meanings attributed to the practice of sport in different scenarios involving players with and without disability, both together and separately. The results show that it is in the specific sport context where players with CP best cope with possible psychological problems caused by discrimination and prejudice from other people without disabilities. In conclusion, the facilitating role of psychomotor and non-competitive practices in inclusive groups is emphasized, as well as the existing inclusive component in sport-specific situations. The results suggest that it is in the specific sport context and in non-competitive psychomotor practices in inclusive groups where athletes with CP best cope with discrimination and prejudice from other people without disabilities. Segregated sport practices become safe environments, which enhances interpersonal relationships among all participants. Like inclusive environments, specific or segregated sport can be an efficient strategy to promote the social inclusion of people with CP.En el presente trabajo se estudia el caso de Maikel, un deportista con parálisis cerebral (PC) que practica deportes tanto en grupo inclusivo como específico o segregado. A partir de la metodología cualitativa se pretende identificar los significados atribuidos a la práctica deportiva en escenarios diversos en los que toman parte deportistas con y sin discapacidad, tanto de forma conjunta como separada. Los resultados sugieren que es en el contexto deportivo específico y en prácticas psicomotrices sin competición en grupos inclusivos donde las y los deportistas con PC mejor hacen frente a la discriminación y los prejuicios de otras personas sin discapacidad. Las prácticas deportivas segregadas se convierten en entornos seguros, lo cual aumenta las relaciones interpersonales entre todas las participantes. Al igual que los entornos inclusivos, el deporte específico o segregado puede ser una estrategia eficiente para promover la inclusión social de las personas con PC

Malignant epithelioid hemangioendothelioma of the liver successfully treated with Sorafenib

Hepatic epithelioid hemangioendothelioma (HEH) is a rare disease of unknown etiology for which a standard systemic treatment has not been established. The common expression of vascular endothelial growth factor (VEGF) and its receptor in HEH provide a rationale for the reported use of antiangiogenic drugs, including bevacizumab, lenalidomide and thalidomide. We report a case of a young male patient with HEH who was treated with sorafenib for almost 2 years. Sorafenib was used instead of other VEGF inhibitors due to its convenient oral route, its dual antiangiogenic and antiproliferative activity, and its favorable safety profile. Sorafenib therapy resulted in durable stabilization with progressive calcification of liver tumors and minor but stable response of lung lesions

Five-year follow-up mortality prognostic index for colorectal patients

Correction to: Five-year follow-up mortality prognostic index for colorectal patients. Int J Colorectal Dis. 2023 Jun 24;38(1):177. doi: 10.1007/s00384-023-04472-z. PMID: 37354325.Purpose: To identify 5-year survival prognostic variables in patients with colorectal cancer (CRC) and to propose a survival prognostic score that also takes into account changes over time in the patient's health-related quality of life (HRQoL) status. Methods: Prospective observational cohort study of CRC patients. We collected data from their diagnosis, intervention, and at 1, 2, 3, and 5 years following the index intervention, also collecting HRQoL data using the EuroQol-5D-5L (EQ-5D-5L), European Organization for Research and Treatment of Cancer's Quality of Life Questionnaire-Core 30 (EORTC-QLQ-C30), and Hospital Anxiety and Depression Scale (HADS) questionnaires. Multivariate Cox proportional models were used. Results: We found predictors of mortality over the 5-year follow-up to be being older; being male; having a higher TNM stage; having a higher lymph node ratio; having a result of CRC surgery classified as R1 or R2; invasion of neighboring organs; having a higher score on the Charlson comorbidity index; having an ASA IV; and having worse scores, worse quality of life, on the EORTC and EQ-5D questionnaires, as compared to those with higher scores in each of those questionnaires respectively. Conclusions: These results allow preventive and controlling measures to be established on long-term follow-up of these patients, based on a few easily measurable variables. Implications for cancer survivors: Patients with colorectal cancer should be monitored more closely depending on the severity of their disease and comorbidities as well as the perceived health-related quality of life, and preventive measures should be established to prevent adverse outcomes and therefore to ensure that better treatment is received.

Enhanced Adipogenic Differentiation of Human Dental Pulp Stem Cells in Enzymatically Decellularized Adipose Tissue Solid Foams

Engineered 3D human adipose tissue models and the development of physiological human 3D in vitro models to test new therapeutic compounds and advance in the study of pathophysiological mechanisms of disease is still technically challenging and expensive. To reduce costs and develop new technologies to study human adipogenesis and stem cell differentiation in a controlled in vitro system, here we report the design, characterization, and validation of extracellular matrix (ECM)-based materials of decellularized human adipose tissue (hDAT) or bovine collagen-I (bCOL-I) for 3D adipogenic stem cell culture. We aimed at recapitulating the dynamics, composition, and structure of the native ECM to optimize the adipogenic differentiation of human mesenchymal stem cells. hDAT was obtained by a two-enzymatic step decellularization protocol and post-processed by freeze-drying to produce 3D solid foams. These solid foams were employed either as pure hDAT, or combined with bCOL-I in a 3:1 proportion, to recreate a microenvironment compatible with stem cell survival and differentiation. We sought to investigate the effect of the adipogenic inductive extracellular 3D-microenvironment on human multipotent dental pulp stem cells (hDPSCs). We found that solid foams supported hDPSC viability and proliferation. Incubation of hDPSCs with adipogenic medium in hDAT-based solid foams increased the expression of mature adipocyte LPL and c/EBP gene markers as determined by RT-qPCR, with respect to bCOL-I solid foams. Moreover, hDPSC capability to differentiate towards adipocytes was assessed by PPAR-γ immunostaining and Oil-red lipid droplet staining. We found out that both hDAT and mixed 3:1 hDAT-COL-I solid foams could support adipogenesis in 3D-hDPSC stem cell cultures significantly more efficiently than solid foams of bCOL-I, opening the possibility to obtain hDAT-based solid foams with customized properties. The combination of human-derived ECM biomaterials with synthetic proteins can, thus, be envisaged to reduce fabrication costs, thus facilitating the widespread use of autologous stem cells and biomaterials for personalized medicine.This research was funded by the Basque Government (IT1751-22; to G.I.; ELKARTEK program 566 PLAKA KK-2019-00093; to N.B.), the Health Department of the Basque Government (grant No. 2021333012; to J.R.P.), and grant No. RYC-2013-13450 and grant No. PID2019-104766RB-C21 funded by MCIN/AEI/10.13039/501100011033 by the European Union (NextGenerationEU) “Plan de Recuperación Transformación y Resiliencia” (grants to J.R.P.)

Endothelial-specific deficiency of megalin in the brain protects mice against high-fat diet challenge

Background: The increasing risk of obesity and diabetes among other metabolic disorders are the consequence of shifts in dietary patterns with high caloric-content food intake. We previously reported that megalin regulates energy homeostasis using blood-brain barrier (BBB) endothelial megalin-deficient (EMD) mice, since these animals developed obesity and metabolic syndrome upon normal chow diet administration. Obesity in mid-life appears to be related to greater dementia risk and represents an increasing global health issue. We demonstrated that EMD phenotype induced impaired learning ability and recognition memory, neurodegeneration, neuroinflammation, reduced neurogenesis, and mitochondrial deregulation associated with higher mitochondrial mass in cortical tissue

Osteogenic differentiation of human dental pulp stem cells in decellularised adipose tissue solid foams

3D cell culture systems based on biological scaffold materials obtainable from both animal and human tissues constitute very interesting tools for cell therapy and personalised medicine applications. The white adipose tissue (AT) extracellular matrix (ECM) is a very promising biomaterial for tissue engineering due to its easy accessibility, malleability and proven biological activity. In the present study, human dental pulp stem cells (hDPSCs) were combined in vitro with ECM scaffolds from porcine and human decellularised adipose tissues (pDAT, hDAT) processed as 3D solid foams, to investigate their effects on the osteogenic differentiation capacity and bone matrix production of hDPSCs, compared to single-protein-based 3D solid foams of collagen type I and conventional 2D tissue-culture-treated polystyrene plates. pDAT solid foams supported the osteogenic differentiation of hDPSCs to similar levels to collagen type I, as assessed by alkaline phosphatase and alizarin red stainings, reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR) and osteocalcin/bone gamma-carboxyglutamate protein (BGLAP) immunostaining. Interestingly, hDAT solid foams showed a markedly lower capacity to sustain hDPSC osteogenic differentiation and matrix calcification and a higher capacity to support adipogenesis, as assessed by RT-qPCR and oil red O staining. White ATs from both human and porcine origins are relatively abundant and available sources of raw material to obtain high quality ECM-derived biomedical products. These biomaterials could have promising applications in tissue engineering and personalised clinical therapy for the healing and regeneration of lesions involving not only a loss of calcified bone but also its associated soft non-calcified tissues.This research was supported by the Basque Government (ELKARTEK program PLAKA KK- 2019-00093; to NB), MICINN retos I+D+i (PID2019- 104766RB-C21, to JRP) and UPV/EHU (PPGA20/22; to FU, GI).

Diversity of mechanisms to control bacterial GTP homeostasis by the mutually exclusive binding of adenine and guanine nucleotides to IMP dehydrogenase.

IMP dehydrogenase(IMPDH) is an essential enzyme that catalyzes the rate-limiting step in the guanine nucleotide pathway. In eukaryotic cells, GTP binding to the regulatory domain allosterically controls the activity of IMPDH by a mechanism that is fine-tuned by post-translational modifications and enzyme polymerization. Nonetheless, the mechanisms of regulation of IMPDH in bacterial cells remain unclear. Using biochemical, structural, and evolutionary analyses, we demonstrate that, in most bacterial phyla, (p)ppGpp compete with ATP to allosterically modulate IMPDH activity by binding to a, previously unrecognized, conserved high affinity pocket within the regulatory domain. This pocket was lost during the evolution of Proteobacteria, making their IMPDHs insensitive to these alarmones. Instead, most proteobacterial IMPDHs evolved to be directly modulated by the balance between ATP and GTP that compete for the same allosteric binding site. Altogether, we demonstrate that the activity of bacterial IMPDHs is allosterically modulated by a universally conserved nucleotide-controlled conformational switch that has divergently evolved to adapt to the specific particularities of each organism. These results reconcile the reported data on the crosstalk between (p)ppGpp signaling and the guanine nucleotide biosynthetic pathway and reinforce the essential role of IMPDH allosteric regulation on bacterial GTP homeostasis.post-print540 K

Preventive behavior against SARS-CoV-2 infection in adults according to whether or not they live with children. A combined analysis of the nationwide COSMO-SPAIN and ENE-COVID surveys

Introduction: The protection of children is a major driver of behavior among those in charge of their care. We evaluated whether compliance with preventive measures against SARS-CoV-2 infection among adults living with children was different from that of those not living with them, in 2020. Methods: We used the COSMO-SPAIN (N = 867) and the nationally representative ENE-COVID (N = 29,926) surveys to estimate prevalence of compliance (95% confidence interval). Logistic model based standardization methods were applied to estimate standardized prevalence differences (SPrD) to the overall distribution of age, sex, education, history of COVID-19, and residence of other >60 yrs in the household. Results: We observed that adults living with children more frequently avoided bars (SPrDENE-COVID: 4.2%; 95% CI: 2.3-6.1), crowded places (SPrDCOSMO: 8.0%; 95% CI: 0.6-15.1) and did not use public transportation (SPrDENE-COVID: 4.9%; 95% CI: 3.0-6.7). They were also more worried about work and family conciliation (SPrDCOSMO: 12.2%; 95% CI: 4.8-19.5) and about closure of education centers (SPrDCOSMO: 26.5%; 95% CI: 19.4-33.6). Discussion: In general, adults living with children adopted slightly more frequently social distancing measures.IJ was hosted in the National Center of Epidemiology, thanks to a grant of Women for Africa 6th edition, with the contribution of ENDESA.
