Estrategias para mejorar el aprendizaje de una lengua extranjera (inglés) con la utilización de las tic en el grado 6º a jornada de la mañana de la i.e.d. lorencita villegas de santos, del banco magdalena

El proyecto realizado está relacionado con estrategias para mejorar y fortalecer el aprendizaje de una lengua extranjera, para este caso, inglés, con la utilización de las TIC para un grado especifico 6 A jornada de la mañana de la Institución Educativa Departamental Lorencita Villegas de Santos de El Banco, Magdalena por medio de un aula virtual. La utilización de una LMS surge por la necesidad de aumentar el nivel de conocimiento en el área de inglés en la Institución desde el pre escolar hasta el grado11 debido a la falta de docentes especializados y a la poca intensidad horaria que contempla el PEI de nuestra Institución, lo cual no se está llevando a cabo, y por ende, al llegar los estudiantes a grado 6 y a grado 11 cuando presentan las pruebas Saber, se ve reflejada la falta de ese conocimiento en el no alcance de las competencias y habilidades comunicativas

Influence of HLA Matching on the Efficacy of Allogeneic Mesenchymal Stromal Cell Therapies for Osteoarthritis and Degenerative Disc Disease

Producción CientíficaThe necessity for more effective therapies for chronic osteoarticular diseases has led to the development of treatments based on mesenchymal stem cells (MSCs), the natural precursors of musculoskeletal tissue. Treatments with autologous MSCs yielded excellent results, with nearly 70% improvement of pain and disability in osteoarthritis and degenerative disc disease. Using allogeneic MSCs is logistically more convenient and would widen the pool of eligible patients, but potential immune rejection should be considered. In this context, MSCs are purportedly immune evasive and better tolerated than other cell types. Methods We used samples collected during the performance of 2 randomized clinical trials using allogeneic bone marrow MSCs for treatment of osteoarthritis (NCT01586312) and degenerative disc disease (NCT01860417). Serum samples were used to determine anti-HLA antibodies, whereas either blood or MSC samples were used for HLA typing of recipients and donors, respectively. Algofunctional indexes were used as indicators of clinical evolution, and the correlation between the number of donor-host HLA mismatches and the efficacy of treatment was determined. Results Immune response was weak and transient, with reactivity decaying during the first year. Consistently, better donor-recipient HLA matching did not enhance efficacy. Conclusions This lack of reactivity is presumably due to the cooperation of 2 factors, (1) downregulation of the host immune responses by the transplanted MSCs and (2) effective insulation of these cells inside the articular cavity or the intervertebral disc, respectively. Interestingly, better HLA matching did not enhance efficacy. These observations have medical relevance as they support the clinical use of allogeneic cells, at least as a single-dose administration. Multiple-dose applications will require further research to exclude possible sensitization.Red de Terapia Celular of the Instituto de Salud Carlos III (RD16/0011/0003) and Centro en Red de Medicina Regenerativa de Castilla y Leó

Outcomes after intensive chemotherapy for secondary and myeloid-related changes acute myeloid leukemia patients aged 60 to 75 years old: a retrospective analysis from the PETHEMA registry

© 2024 Ferrata Storti Foundation Published under a CC BY-NC license.Treatment options for patients with secondary acute myeloid leukemia (sAML) and AML with myeloid-related changes (AMLMRC) aged 60 to 75 years are scarce and unsuitable. A pivotal trial showed that CPX-351 improved complete remission with/without incomplete recovery (CR/CRi) and overall survival (OS) as compared with standard "3+7" regimens. We retrospectively analyze outcomes of 765 patients with sAML and AML-MRC aged 60 to 75 years treated with intensive chemotherapy, reported to the PETHEMA registry before CPX-351 became available. The CR/CRi rate was 48%, median OS was 7.6 months (95% confidence interval [CI]: 6.7-8.5) and event-free survival (EFS) 2.7 months (95% CI: 2-3.3), without differences between intensive chemotherapy regimens and AML type. Multivariate analyses identified age ≥70 years, Eastern Cooperative Oncology Group performance status ≥1 as independent adverse prognostic factors for CR/CRi and OS, while favorable/intermediate cytogenetic risk and NPM1 were favorable prognostic factors. Patients receiving allogeneic stem cell transplant (HSCT), autologous HSCT, and those who completed more consolidation cycles showed improved OS. This large study suggests that classical intensive chemotherapy could lead to similar CR/CRi rates with slightly shorter median OS than CPX-351.This study was partially supported by the Jazz Pharmaceuticals and Cooperative Research Thematic Network (RTICC) grant RD12/0036/014 (ISCIII & ERDF).Peer reviewe

Intersectoriality as a managerial technology in Cuba voluntary blood donations

In Cuba there is wide experience in intersectoral work to solve health problems in the community and the management of blood donations is no exception. The objective of this work was to document the intersectoral work in the management of blood donations in Cuba and to provide theoretical elements that contribute to its improvement. A bibliographic review of the literature on intersectoriality and the processes for the management of blood donations in the country was carried out; For this, works published on Internet sites were consulted, as well as texts and other documents available in repositories of the Infomed web portal network. Intersectoriality is theorized and illustrated as a managerial technology and its use and importance applied in the promotion, capture and recruitment of potential donors and in the organization of blood collections. It is concluded that the use of intersectoriality in the health management of voluntary blood donations, strengthens and distinguishes the Cuban Blood Donation Program in relation to the rest of the world, however, it is necessary to improve the strategic alliances between the health sector and other sectors of organized civil society involved in the activities that comprise this process

Intervertebral disc repair by allogeneic mesenchymal bone marrow cells: A randomized controlled trial

et al.[Background]: Degenerative disc disease often causes severe low-back pain, a public health problem with huge economic and life quality impact. Chronic cases often require surgery, which may lead to biomechanical problems and accelerated degeneration of the adjacent segments. Autologous mesenchymal stromal cells (MSC) treatments have shown feasibility, safety and strong indications of clinical efficacy. We present here a randomized, controlled trial using allogeneic MSC, which are logistically more convenient than autologous cells. [Methods]: We randomized 24 patients with chronic back pain diagnosed with lumbar disk degeneration and unresponsive to conservative treatments into 2 groups. The test group received allogeneic bone marrow MSCs by intradiscal injection of 25 × 10 cells per segment under local anesthesia. The control group received a sham infiltration of paravertebral musculature with the anesthetic. Clinical outcomes were followed up for 1 year and included evaluation of pain, disability, and quality of life. Disc quality was followed up by magnetic resonance imaging. [Results]: Feasibility and safety were confirmed and indications of clinical efficacy were identified. MSC-treated patients displayed a quick and significant improvement in algofunctional indices versus the controls. This improvement seemed restricted to a group of responders that included 40% of the cohort. Degeneration, quantified by Pfirrmann grading, improved in the MSC-treated patients and worsened in the controls. [Conclusions]: Allogeneic MSC therapy may be a valid alternative for the treatment of degenerative disc disease that is more logistically convenient than the autologous MSC treatment. The intervention is simple, does not require surgery, provides pain relief, and significantly improves disc quality.Financial support from the Red de Terapia Celular (RD12/0019/0036, RD12/0019/0001 and RD16/0011/0003), Instituto de Salud Carlos III, Ministerio de Economía y Competitividad, and the Centro en Red de Medicina Regenerativa de Castilla y León is gratefully acknowledged.Peer Reviewe

Evolving treatment patterns and outcomes in older patients (≥60 years) with AML: changing everything to change nothing?

There are no studies analyzing how therapeutic changes impact on outcomes of older AML patients. This study analyzes patient´s and disease characteristics, treatment patterns, and outcomes of 3637 AML patients aged ≥60 years reported to the PETHEMA registry. Study periods were 1999–2006 (before hypomethylating agents-HMAs availability) vs 2007–2013, and treatments were intensive chemotherapy (IC), non-intensive, clinical trial (CT), and supportive care only (SC). Median age was 72 (range, 60–99), 57% male, median ECOG 1 (range, 0–4), secondary AML 914 (30%), with adverse-risk genetic in 720 (32%). Treatment differed between study periods (1999–2006 vs 2007–2013): IC 58% vs 32%, non-intensive 1 vs 23%, CT 0 vs 2%, SC 27 vs 28% (p < 0.001). Median OS was 4.7 months (1-year OS 29% and 5-years 7%, without differences between periods), 1.2 for SC, 7.8 for non-intensive, 8.6 for IC, and 10.4 for CT (p < 0.001). OS improved in the 2007–2013 period for IC patients (10.3 vs 7.5 months, p = 0.004), but worsened for SC patients (1.2 vs 1.6 months, p = 0.03). Our real-life study shows that, despite evolving treatment for elderly patients during the last decade, OS has remained unchanged. Epidemiologic registries will critically assess whether novel therapies lead to noteworthy advances in the near future (#NCT02606825).This study was supported in part by Janssen Pharmaceutica, and the Cooperative Research Thematic Network (RTICC) (Grant RD12/0036/014 (ISCIII & ERDF)
