Longitudinal Study of Cytokine Expression, Lipid Profile and Neuronal Growth Factors in Human Breast Milk from Term and Preterm Deliveries
2015
Breast milk (BM) is considered as a reference for infant nutrition. The role of bioactive components, such as cytokines, hormones, growth factors (GFs) and fatty acids (FAs) is poorly known, but they might be implicated in immune response development. The aim of this study was to identify the lipid profile and the spectrum of cytokines and neuronal GF in BM samples and analyse the influence of gestational age and lactation time on these components. This study used a longitudinal prospective method for the characterization of cytokines, FAs and GFs global profiles in 120 BM samples from 40 healthy mothers (20 preterm and 20 term) collected as colostrum, transitional and mature milk. The cyto…
Bruxismo Infantil: Estudio de factores intrínsecos y ambientales en su etiología
2020
El bruxismo se define como un comportamiento, que incluye movimientos involuntarios, de los músculos de la masticación además de un contacto dental no funcional, apretando y/o rechinando los dientes. Puede ocurrir durante el día y /o la noche, en este último caso, suele suceder en micro despertares en la primera y segunda fase del sueño no REM. El bruxismo afecta por igual a ambos sexos y tiende a disminuir con la edad. La prevalencia obtenida en los diferentes estudios publicados oscila entre el 3,5% al 88%, aunque la mayoría se sitúan en un intervalo de prevalencia comprendido entre el 3,5 y el 40,6% . Los síntomas más frecuentes relativos al bruxismo son: dolor en la articulación temporo…
Relación del Índice de Masa Corporal elevado asociado a la postura del pie y la actividad deportiva en la edad pediátrica
2019
[Resumen] Objetivos: Establecer el tipo de pie y el Índice de Masa Corporal que predomina en la edad pediátrica. Material y métodos: Se ha realizado una descriptiva de la muestra estudio analizando la prueba del Foot Posture Índex y el Índice de Masa Corporal a 31 sujetos de 8 años. También se ha analizado la actividad deportiva y la frecuencia con la que se realiza además de valorar si llevaban tratamiento ortopodológico. Resultados: El 50% de la muestra presenta pies pronados. El Índice de Masa Corporal es mayor en el sexo masculino, siendo el 30% de los sujetos los que presentan sobrepeso y el 12% de la muestra obesidad. Conclusiones: No se puede concluir que los pacientes con un Índice …
Infantile Hemangioma Detection using Deep Learning
2020
Infantile hemangiomas are the most common type of benign tumor which appear in the first weeks of life. As currently there is no robust protocol to monitor and assess the hemangioma status, this study proposes a preliminary method to detect the lesion. Therefore, in this paper we describe a hemangiomas classifier based on a linear convolutional neural network architecture. The challenge was to achieve a good classification using a relatively small internal database of 240 images from 40 different patients. The results are promising as the CNN performance evaluation showed a level of accuracy on the test set of 93.84%. Five metrics were calculated to assess the proposed model performances: a…
Thymic transplantation for relief of immunodeficiency diseases.
1979
Tremendous advances have been made in replacement therapy regimens for the correction of immunodeficiency in transplant patients. Recently, cultured thymic fragments were shown to be devoid of lethal graft-versus-host cells and research in this area indicates that thymic transplantation may have a sustained positive effect in immunosuppressed patients.
Saving Lives at Birth: The Impact of Home Births on Infant Outcomes
2012
Many developed countries have recently experienced sharp increases in home birth rates. This paper investigates the impact of home births on the health of low-risk newborns using data from the Netherlands, the only developed country where home births are widespread. To account for endogeneity in location of birth, we exploit the exogenous variation in distance from a mother’s residence to the closest hospital. We find that giving birth in a hospital leads to substantial reductions in newborn mortality. We provide suggestive evidence that proximity to medical technologies may be an important channel contributing to these health gains.
Diagnosis of the neuronal ceroid lipofuscinoses: An update
2006
Abstract For the majority of families affected by one of the neuronal ceroid lipofuscinoses (NCLs), a biochemical and/or genetic diagnosis can be achieved. In an individual case this information not only increases understanding of the condition but also may influence treatment choices and options. The presenting clinical features prompt initial investigation and also guide clinical care. The clinical labels “infantile NCL”, “late infantile NCL” and “juvenile NCL”, therefore remain useful in practice. In unusual or atypical cases ultra-structural analysis of white blood cells or other tissue samples enables planning and prioritisation of biochemical and genetic tests.This review describes cu…

Amino acid contents of infant foods.
2006
The protein quality of three milk-cereal-based infant foods (paps) was evaluated by determining their amino acid contents and calculating the amino acid score. Proteins were subjected to acid hydrolysis, prior to which cysteine and methionine were oxidized with performic acid. Amino acids were determined by reverse-phase high-performance liquid chromatography with fluorescence detection with a prior derivatization with 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate. Tryptophan was determined by reverse-phase high-performance liquid chromatography with ultraviolet detection after basic hydrolysis. Glutamic acid, proline and leucine were the most abundant amino acids, whereas tryptophan and …
“Click” on PLGA-PEG and hyaluronic acid: Gaining access to anti-leishmanial pentamidine bioconjugates
2017
Pentamidine (Pent), an antiparasitic drug used for the treatment of visceral leishmaniasis, has been modified with terminal azide groups and conjugated to two different polymer backbones (PLGA-PEG [PP] copolymer and hyaluronic acid [HA]) armed with alkyne end-groups. The conjugation has been performed by Copper Catalyzed Azido Alkyne Cycloaddition (CuAAC) using CuSO4 /sodium ascorbate as metal source. The novel PP-Pent and HA-Pent bioconjugates are proposed, respectively, as non-targeted and targeted drug delivery systems against Leishmania infections. Moreover, Pent has been encapsulated into PP nanoparticles by the oil-in-water emulsion method, with the aim to compare the biological activ…
