The influence of healthy habits acquired by school-age adolescents in relation to physical education classes

The main aim of this research is to know the habits of our students due to our concern to educate students about the importance of caring for and improving their health. Students of the First Cycle of ESO of the Centres of the Cordoba regions of the south of the province have fulfilled a survey about their daily habits related to health; In addition, to know the thoughts, beliefs and knowledge of the Physical Education teachers of these students through the conduct of a Discussion Group, in order to learn more about this perspective in relation to Physical Education and Education for Health. Among other data from the analysis and taking into account the food pyramid for these ages, it can be deduced that the students eat few vegetables and that a percentage close to 25% of the students consumes sweets 3-4 days a week. It is noteworthy that 59.3% of boys and 24.1% of girls regularly do physical activity, apart from the Physical Education class. Regarding the teaching sector, teachers thinks that students are aware of what is advisable to take and what is not; since in schools the diet is changing towards healthier habits, however, the students sometimes eat food that is not conducive to them and they do not even eat. As for hygiene habits, the teachers say that they are consolidated, but the same does not happen with postural habits that they consider not to have correct habits

A escola como agente de socialização e sua influência na aquisição e manutenção de hábitos saudáveis e não saudáveis

Introducción: Mediante ciertos entes de la sociedad que llamamos “agentes” se realiza la socialización, porque permiten que ésta tenga lugar, dichos agentes son por excelencia, la familia, el “grupo de pares”, la escuela y los medios de comunicación. A través de este trabajo de investigación concretamente estudiaremos la influencia que uno de ellos, la escuela, tiene sobre la adquisición y mantenimiento de hábitos saludables y no saludables en el alumnado de Educación Secundaria. La información para comprobar el grado de influencia se obtiene a través de las opiniones del profesorado de Educación Física expresadas en un Grupo de Discusión, así como, de las respuestas del alumnado a los ítems de un cuestionario validado debidamente.Introduction: Through certain entities of the society that we call "agents", socialization takes place, because they allow it to take place, these agents are par excellence, the family, the "peer group", the school and the media.

NKG2D-CAR memory T cells target pediatric T-cell acute lymphoblastic leukemia in vitro and n vivo but fail to eliminate leukemiai nitiating cells

[Introduction]: Refractory/relapsed pediatric acute leukemia are still clinically challenging and new therapeutic strategies are needed. Interactions between Natural Killer Group 2D (NKG2D) receptor, expressed in cytotoxic immune cells, and its ligands (NKG2DL), which are upregulated in leukemic blasts, are important for anti-leukemia immunosurveillance. Nevertheless, leukemia cells may develop immunoescape strategies as NKG2DL shedding and/or downregulation. [Methods]: In this report, we analyzed the anti-leukemia activity of NKG2D chimeric antigen receptor (CAR) redirected memory (CD45RA-) T cells in vitro and in a murine model of T-cell acute lymphoblastic leukemia (T-ALL). We also explored in vitro how soluble NKG2DL (sNKG2DL) affected NKG2D-CAR T cells’ cytotoxicity and the impact of NKG2D-CAR T cells on Jurkat cells gene expression and in vivo functionality. [Results]: In vitro, we found NKG2D-CAR T cells targeted leukemia cells and showed resistance to the immunosuppressive effects exerted by sNKG2DL. In vivo, NKG2D-CAR T cells controlled T cell leukemia burden and increased survival of the treated mice but failed to cure the animals. After CAR T cell treatment, Jurkat cells upregulated genes related to proliferation, survival and stemness, and in vivo, they exhibited functional properties of leukemia initiating cells. [Discussion]: The data here presented suggest, that, in combination with other therapeutic approaches, NKG2D-CAR T cells could be a novel treatment for pediatric T-ALL.This work was supported by a grant from the Instituto de Salud Carlos III to LF PI21/01049, the II and V awards from UNOENTRECIENMIL Foundation, and a grant from CRIS FOUNDATION to Beat Cancer as part of the projects “Cell therapy based on NKG2D-CAR for pediatric leukemia” and “NKG2D-CAR as treatment for pediatric patients suffering from acute leukemia and juvenile myelomonocytic leukemia”.

Optimizing the procedure to manufacture clinical‐grade NK cells for adoptive immunotherapy

Natural killer (NK) cells represent promising tools for cancer immunotherapy. We report the optimization of an NK cell activation–expansion process and its validation on clinical‐scale. Methods: RPMI‐1640, stem cell growth medium (SCGM), NK MACS and TexMACS were used as culture mediums. Activated and expanded NK cells (NKAE) were obtained by coculturing total peripheral blood mononuclear cells (PBMC) or CD45RA+ cells with irradiated K562mbIL15‐41BBL or K562mbIL21‐41BBL. Fold increase, NK cell purity, activation status, cytotoxicity and transcriptome profile were analyzed. Clinical‐grade NKAE cells were manufactured in CliniMACS Prodigy. Results: NK MACS and TexMACs achieved the highest NK cell purity and lowest T cell contamination. Obtaining NKAE cells from CD45RA+ cells was feasible although PBMC yielded higher total cell numbers and NK cell purity than CD45RA+ cells. The highest fold expansion and NK purity were achieved by using PBMC and K562mbIL21‐41BBL cells. However, no differences in activation and cytotoxicity were found when using either NK cell source or activating cell line. Transcriptome profile showed to be different between basal NK cells and NKAE cells expanded with K562mbIL21‐41BBL or K562mbIL15‐41BBL. Clinical‐grade manufactured NKAE cells complied with the specifications from the Spanish Regulatory Agency. Conclusions: GMP‐grade NK cells for clinical use can be obtained by using different starting cells and aAPCThis work was supported by the National Health Service of Spain, Instituto de Salud Carlos III (ISCIII), FONDOS FEDER grant (FIS) PI18/01301 to Pérez-Martínez A, CRIS Foundation to Beat Cancer to Escudero A, Fernández A; Navarro A, Mirones I, and Fundación Mari Paz Jiménez Casado and La Sonrisa de Álex to Vela

Prognosis Stratification Tools in Early-Stage Endometrial Cancer: Could We Improve Their Accuracy?

There are three prognostic stratification tools used for endometrial cancer: ESMO-ESGO-ESTRO 2016, ProMisE, and ESGO-ESTRO-ESP 2020. However, these methods are not sufficiently accurate to address prognosis. The aim of this study was to investigate whether the integration of molecular classification and other biomarkers could be used to improve the prognosis stratification in early-stage endometrial cancer. Relapse-free and overall survival of each classifier were analyzed, and the c-index was employed to assess accuracy. Other biomarkers were explored to improve the precision of risk classifiers. We analyzed 293 patients. A comparison between the three classifiers showed an improved accuracy in ESGO-ESTRO-ESP 2020 when RFS was evaluated (c-index = 0.78), although we did not find broad differences between intermediate prognostic groups. Prognosis of these patients was better stratified with the incorporation of CTNNB1 status to the 2020 classifier (c-index 0.81), with statistically significant and clinically relevant differences in 5-year RFS: 93.9% for low risk, 79.1% for intermediate merged group/CTNNB1 wild type, and 42.7% for high risk (including patients with CTNNB1 mutation). The incorporation of molecular classification in risk stratification resulted in better discriminatory capability, which could be improved even further with the addition of CTNNB1 mutational evaluation.Peer reviewe

Advanced Molecular Characterisation in Relapsed and Refractory Paediatric Acute Leukaemia, the Key for Personalised Medicine

Relapsed and refractory (R/r) disease in paediatric acute leukaemia remains the first reason for treatment failure. Advances in molecular characterisation can ameliorate the identification of genetic biomarkers treatment strategies for this disease, especially in high-risk patients. The purpose of this study was to analyse a cohort of R/r children diagnosed with acute lymphoblastic (ALL) or myeloid (AML) leukaemia in order to offer them a targeted treatment if available. Advanced molecular characterisation of 26 patients diagnosed with R/r disease was performed using NGS, MLPA, and RT-qPCR. The clinical relevance of the identified alterations was discussed in a multidisciplinary molecular tumour board (MTB). A total of 18 (69.2%) patients were diagnosed with B-ALL, 4 (15.4%) with T-ALL, 3 (11.5%) with AML and 1 patient (3.8%) with a mixed-phenotype acute leukaemia (MPL). Most of the patients had relapsed disease (88%) at the time of sample collection. A total of 17 patients (65.4%) were found to be carriers of a druggable molecular alteration, 8 of whom (47%) received targeted therapy, 7 (87.5%) of them in addition to hematopoietic stem cell transplantation (HSCT). Treatment response and disease control were achieved in 4 patients (50%). In conclusion, advanced molecular characterisation and MTB can improve treatment and outcome in paediatric R/r acute leukaemias

Whole-Exome Sequencing of 24 Spanish Families: Candidate Genes for Non-Syndromic Pediatric Keratoconus

Keratoconus is a corneal dystrophy that is one of the main causes of corneal transplantation and for which there is currently no effective treatment for all patients. The presentation of this disease in pediatric age is associated with rapid progression, a worse prognosis and, in 15–20% of cases, the need for corneal transplantation. It is a multifactorial disease with genetic variability, which makes its genetic study difficult. Discovering new therapeutic targets is necessary to improve the quality of life of patients. In this manuscript, we present the results of whole-exome sequencing (WES) of 24 pediatric families diagnosed at the University Hospital La Paz (HULP) in Madrid. The results show an oligogenic inheritance of the disease. Genes involved in the structure, function, cell adhesion, development and repair pathways of the cornea are proposed as candidate genes for the disease. Further studies are needed to confirm the involvement of the candidate genes described in this article in the development of pediatric keratoconus
