Published: September 2023

La investigación sobre educación especial ha crecido de manera sustancial en los últimos años. En este documento se ofrece una visión general de la investigación sobre educación especial llevada a cabo en Europa en la última década, la cual está basada en un análisis de los documentos publicados en la European Journal of Special Needs Education (Revista) entre los años 1998 a 2007. En estos se cubrió un amplio rango de temas, entre los que se encuentran: padres, familia, docentes y sus actitudes, políticas en educación especial, desarrollo social y emocional de los alumnos, oferta y desarrollo del lenguaje a temprana edad. Muchos de los documentos fueron empíricos, tanto cuantitativos como cualitativos, aunque también se publicaron un buen número de teóricos y descriptivos. Aunque los textos se originaron en Europa, la gran mayoría provienen del Reino Unido, los Países Bajos, países escandinavos, Israel y Grecia. Para el futuro, se recomienda una mayor concentración de esfuerzos en cuanto a investigación, así como mayor atención a algunos temas clave que hasta el momento han sido poco investigados.Descriptores: Investigación, europa, educación especial Special Education Research in EuropeResearch in special education has grown substantially in recent years.

El Acceso y el Abandono de la Educación Básica Obligatoria en México, 1990-2005. Balance Demográfico de las Oportunidades Educativas de los Jóvenes de 15 a 19 años
Authors: Tapia Guillermo 
Published: September 2023

Las reformas educativas impulsadas en 1990 y 2000 se justificaron en México con el objetivo de mejorar la calidad de la educación. Varias políticas buscaron mejorar la eficiencia del sistema educativo. Otras se orientaron hacia una mayor equidad en la distribución de oportunidades educativas. Este trabajo pretende observar el comportamiento de los indicadores básicos de acceso y abandono de la educación básica por parte de la población de 15 a 19 años, en el periodo 1990-2005. Este grupo etario permite verificar el impacto general de las políticas federales orientadas a favorecer un mayor acceso y permanencia de la población en la educación básica obligatoria, considerando que la educación secundaria fue declarada como tal en 1993. La observación se realiza desde una perspectiva demográfica. Se analizan los datos como indicadores de resultado. La población observada superó la edad normativa (15 años) para cursar la educación básica formal en los servicios regulares. El análisis se realiza en dos ejes: trasversal (entidades federativas) y longitudinal (años 1990-2000-2005). Esto permite apreciar algunos efectos de las políticas compensatorias, en combinación con la dinámica de la población. Descriptores: Exclusión educativa, igualdad de oportunidades, indicadores educativos, educación básica, México. The Access and Abandonment of the Mandatory Basic Education in Mexico, 1990-2005. Demographic Balance of Educational Opportunities the 15 to 19 year oldsThe educational reforms promoted in 1990 and 2000 were justified in Mexico to improve the quality of education. Several policies are oriented to improve the efficiency of the education system. Others were directed towards a more equitable distribution of educational opportunities. This work aims to observe the behavior of the core indicators of access and neglect of basic education by the population 15 to 19 years in the period 1990-2005. This age group can verify the overall impact of federal policies designed to increase access and retention of people in the compulsory basic education, whereas education was declared as such in 1993. The observation is made from a demographic perspective. The data analysis make with outcome indicators. The population observed over the age rules (15 years) to attend formal education in the regular services. The analysis is performed in two directions: transversal (states) and longitudinal (years 1990-2000-2005). Here we can see some effects of compensation policy, in combination with population dynamics.Keywords: Educational exclusion, equal opportunities, education indicators, basic education, México.
The Senior Resident–Fellow Dynamic on Pediatric Hospital Medicine Teams: A Qualitative Study
Authors: Barak Gal , Dean Andrea , Haq Heather , Falco Carla , Singhal Geeta 
Published: September 2023

BACKGROUND AND OBJECTIVES
With the Accreditation Council for Graduate Medical Education accreditation in place for pediatric hospital medicine (PHM) fellowships, fellows are playing a larger role in resident education. However, the impact of PHM fellows on pediatric residency training is not well described. We aimed to identify the factors that affect the dynamic between senior residents and fellows working together on PHM teams.

METHODS
In this qualitative study, we used purposive sampling and interviewed 15 senior residents and 8 PHM fellows between April and September 2020. We created a conceptual framework for the senior resident–fellow dynamic to develop the interview guide. Using verbatim transcripts uploaded into Dedoose software, 2 authors coded responses and identified themes using directed content analysis.

RESULTS
Twelve themes emerged as factors that impact the senior resident–fellow dynamic and fell into 6 categories: Team organization, role clarity, teaching, fellow approachability, decision-making, and attending involvement. Both senior residents and PHM fellows described an optimal dynamic in which a hierarchal approach to team structure, teaching, and decision-making is counterbalanced by fellow approachability. Role uncertainty, especially with increased attending involvement, led to conflict between residents and fellows.

CONCLUSIONS
This study demonstrated that a structured hierarchy surrounding supervision, decision-making, and teaching promoted level-appropriate autonomy for both senior residents and fellows. These findings can be used to design an intervention, such as a leadership curriculum for fellows and senior residents, to target behaviors that facilitate a stepwise approach to supervision and patient care.

Effects of anobiid damage on shear strength parallel to the grain in single step joints
Authors: Lima Daniel F. , Branco Jorge M. , Parracha João , Machado José S. , Nunes Lina 
Published: September 2023

AbstractTraditional carpentry joints can be found worldwide in many timber truss structures connecting rafter and tie beam. One failure mode of this connection result from shear in the tie beam beyond the notch either due to bad design or deterioration. In this article, the reduction in shear strength of Single Step Joints (SSJ) resulting from biological attack by anobiids was analysed. For this purpose, tests were carried out in non-degraded scots pine (Pinus sylvestris L.) specimens (reference) and compared to artificially degraded specimens with three different levels of degradation. The reduction of shear resistance was analysed in relation to the density of holes drilled during the degradation simulation, the loss of mass, and the reduction of the shear-resistant area. At lower degradation levels, no significant reduction in shear strength was observed. On the other hand, the linear regression shows a trend of resistance reduction with increasing degradation. Despite the relatively low coefficient of determination (r2 = 0.25), the parameter that best correlated with the residual strength was the reduction in the shear-resistant area.
Interfacial bond strength and failure modes of traditional and modern repair materials for historic fibrous plaster

Published: September 2023

AbstractMany culturally important historic buildings contain fibrous plaster ceilings. The collapse at London’s Apollo Theatre in 2013, which injured 88 people, highlighted the importance of inspecting and restoring ceilings effectively. This study focuses on traditional and modern materials which are applied to the topsides of existing historic fibrous plaster ceiling elements during repair and maintenance. Fibrous plaster ceilings are commonly suspended from primary or secondary structural roof members using fibrous plaster wadding ties or ‘wads’. The application of additional repair material requires the formation of an interface, defining the strength of the repair. Properties of this interface were evaluated through a novel methodology employing pull-off tests’ of approximately 200 specimens consisting of Alpha plaster, Beta plaster, Jesmonite and Aramid gel. Notably, the effect of fibrous reinforcement, and compatibility with historic and degraded material was also investigated. This study has enabled quantification of interfacial properties and evaluated cohesive and adhesive failure modes. Importantly, the extent of redundancy within historic plaster ceiling practice has been demonstrated, with pull-off occurring from 0.5 kN to 2 kN loading, and the ductile behaviour of repair materials evaluated. Results highlight the importance of surface condition, with clean surfaces exhibiting double the tensile loading capacity compared to soiled (dirty) surfaces representative of those encountered on-site. The significance of this study lies in the quantification of repair material performances and consideration of variations in performance, methodology and in-situ environmental factors. Impact stems from the ability of practitioners to make informed decisions relating to adhesion performance when carrying out repairs. A key outcome is more effective preservation of historic elements in heritage buildings, higher levels of safety and serviceability.

Background. Tumor cell proliferation in acute myeloid leukemia (AML) may manifest with high leukocyte counts. In our work, we evaluate the association of high leukocyte counts with individual mutations, as well as their total contribution to the development of leukocytosis in AML. The results obtained should improve our understanding of pathogenic mechanisms leading to the leukocytosis in AML.Aim. To study the genetic landscape of AML with leukocytosis.Materials and methods. The laboratory data of 214 AML patients admitted to the National Medical Research Center for Hematology (Moscow) from 2010 to 2022 were retrospectively examined. Real-time PCR, capillary electrophoresis and NGS (next generation sequencing) methods were used to detect mutations of FLT3, NPM1, CEBPA, IDH1/2, DNMT3A, TET2 genes, and CBFB::MYH11, RUNX1::RUNX1T1 chimeric gene transcripts.Results. Mutations of the FLT3 gene (odds ratio 5.45; p < 0.0001), inv(16)/CBFB::MYH11 (odds ratio 10.03; p = 0.0009) are most associated with leukocyte counts higher than 30 × 109 / L in the debut of AML. Translocation t(8;21)/RUNX1::RUNX1T1 and adverse cytogenetic aberrations, such as -5/del(5q); -7 / del(7q); -17 / abn(17p), complex and monosomic karyotype were significantly associated with leukocyte counts lower than 30 × 109 / L at the time of disease manifestation (p < 0.0001). In the group of patients with intermediate cytogenetic risk bearing only IDH1/2, DNMT3A, and TET2 gene mutations, leukocyte counts at AML debut were significantly lower, whereas the most pronounced leukocytosis was observed in patients with a combination of driver mutations with IDH1/2, DNMT3A, and TET2 gene mutations or FLT3, NPM1, and CEBPA gene mutations.Conclusion. In addition to the individual effect of certain genetic lesions and cytogenetic aberrations on the proliferative potential of tumor cells, there is a total contribution of various types of genetic events to the development of leukocytosis in AML. High leukocyte counts at the time of AML manifestation in patients with intermediate cytogenetic risk can serve as an indirect marker of the presence of a large number of genetic aberrations with a combination of IDH1/2, DNMT3A, and TET2 gene mutations or FLT3, NPM1, and CEBPA gene mutations.

Background. Patients with B-cell lymphoma have an extremely unfavorable prognosis after relapse or in case of refractoriness to the first and consecutive lines of immunochemotherapy with the anti-CD19 CAR-T cells being the only therapeutic option to such patients. the manual preparation of anti-CD19 CAR-T lymphocytes was reproduced in the N. N. Alexandrov republican research and practical center for oncology and medical radiology (Minsk). Their safety was demonstrated. Aim. To estimate safety, tolerability and efficacy of the in-house CAR-T cells, including objective response rate, progression-free and overall survival. Materials and methods. The second generation anti-CD19 chimeric antigen receptor contained an anti-CD19 antibody scFv fragment, CD28 transmembrane domain, 4-1BB and CD3z signaling domains. the coding sequence was cloned into the lentiviral vector S4. The cell product was obtained by expansion of CD4- and CD8-positive lymphocytes populations with IL-7 and IL-15 after initial activation and lentiviral transduction with vector S4. CAR-T cells were infused into 8 patients with refractory forms of B-cell lymphoma after the preliminary lymphodepleting chemotherapy. Persistence of CAR-T cells was assessed by flow cytometry. therapeutic efficiency was assessed by positron emission tomography-computed tomography with 18F-fluorodeoxyglucose. Results. Expansion of CAR-T cells with resulting b-cell aplasia was observed in all patients. the median of observation was 113 days (range 22–529 days). objective response rate was 100 %, complete remission was observed in 6 patients, partial response – in 1 patient. One patient died because of complications before the clinical response. Overall survival was 88 ± 12 %. cytokine release syndrome and neurotoxicity were not observed in 6 out of 8 patients despite a high tumor burden. Conclusion. Our study demonstrated efficiency and safety of the in-house CAR-T cells for the treatment of patients with refractory B-cell lymphomas.
