Rol del terapeuta ocupacional en la evaluación y tratamiento de prematuros en las unidades de cuidados intensivos neonatales. Revisión sistemática / Occupational therapist role in the assessment and treatment of premature infants in neonatal intensive care units. A systematic review

OBJETIVOS: conocer las diferentes funciones del o de la terapeuta ocupacional en las Unidades de Cuidados de Neonatología en la evaluación y tratamiento de prematuros menores de 1500g. MÉTODO: se realizó una revisión bibliográfica utilizando 3 bases de datos donde fueron seleccionados los artículos que daban respuesta a la pregunta de estudio para conocer el trabajo de la persona profesional terapeuta ocupacional en las unidades neonatales durante los últimos 15 años. RESULTADOS: fueron evaluados un total de dieciseis estudios en los que se incluye al terapeuta ocupacional como profesional de las unidades UCI, donde se resalta que el es el que debe llevar a cabo técnicas y procesos, que permitan continuar con su crecimiento y desarrollo neurológico. CONCLUSIÓN: se concluye que, sería conveniente llevar a cabo más estudios para demostrar la necesidad de terapia ocupacional en unidades de neonatología

OBJECTIVE: To know the different occupational therapist duties in neonatal intensive care units in the evaluation and treatment of premature infants with birth weight under 1500g. METHOD: A bibliographic review was carried out using 3 databases selecting only those studies answering the study question, that is, occupational therapy's role in neonatal units throughout the last 15 years. RESULTS: Sixteen studies were evaluated in which an occupational therapist was included as part of the intensive care unit, emphasizing their role as the health care professional in charge of implementing the techniques and processes which allow infants to continue their growth and neurological development. CONCLUSION: Further studies are necessary in order to prove the need of occupational therapy practitioners in neonatal units

Infection Exposure Promotes ETV6-RUNX1 Precursor B-cell Leukemia via Impaired H3K4 Demethylases.

ETV6-RUNX1 is associated with the most common subtype of childhood leukemia. As few ETV6-RUNX1 carriers develop precursor B-cell acute lymphocytic leukemia (pB-ALL), the underlying genetic basis for development of full-blown leukemia remains to be identified, but the appearance of leukemia cases in time-space clusters keeps infection as a potential causal factor. Here, we present in vivo genetic evidence mechanistically connecting preleukemic ETV6-RUNX1 expression in hematopoetic stem cells/precursor cells (HSC/PC) and postnatal infections for human-like pB-ALL. In our model, ETV6-RUNX1 conferred a low risk of developing pB-ALL after exposure to common pathogens, corroborating the low incidence observed in humans. Murine preleukemic ETV6-RUNX1 pro/preB cells showed high Rag1/2 expression, known for human ETV6-RUNX1 pB-ALL. Murine and human ETV6-RUNX1 pB-ALL revealed recurrent genomic alterations, with a relevant proportion affecting genes of the lysine demethylase (KDM) family. KDM5C loss of function resulted in increased levels of H3K4me3, which coprecipitated with RAG2 in a human cell line model, laying the molecular basis for recombination activity. We conclude that alterations of KDM family members represent a disease-driving mechanism and an explanation for RAG off-target cleavage observed in humans. Our results explain the genetic basis for clonal evolution of an ETV6-RUNX1 preleukemic clone to pB-ALL after infection exposure and offer the possibility of novel therapeutic approaches.
