Automatic segmentation of a cerebral glioblastoma using a smart computational technique
(Sociedad Venezolana de Farmacología Clínica y Terapéutica, 2018)
We propose an intelligent computational technique for the
image segmentation of a type IV brain tumor, identified as
multiform glioblastoma (MGB), which is present in multi-layer
computed tomography images. This technique consists of
3 stages developed in the three-dimensional domain. They
are: pre-processing, segmentation and validation. During the
validation stage, the Dice coefficient (Dc) is considered in
order to compare the segmentations of the MGB, obtained
automatically, with the segmentations of the MGB generated
manually, by a ...
Comparación de índices antropométricos para agregación de múltiples factores de riesgo en adultos de Cuenca, Ecuador
(Instituto Nacional de Salud, 2018)
Objetivos. El objetivo de este estudio es comparar la capacidad predictiva de diferentes índices antropométricos en la
determinación de la agregación de múltiples factores de riesgo (AMFR) en la población adulta de la ciudad de Cuenca,
Ecuador. Materiales y métodos. Se realizó un estudio descriptivo transversal con un muestreo aleatorio multietápico en
318 sujetos adultos a quienes se les realizó una evaluación clínica, antropométrica y de laboratorio; siendo la circunferencia
abdominal, índice de masa corporal (IMC) e índice cintura altura ...
Importance of high triglycerides levels between novel coronary risk factors
(Sociedad Colombiana de Cardiología y Cirugía Cardiovascular., 2017-11)
Introduction: The analysis of new cardiovascular risk factors is under an extensive debate in
the cardiology and metabolic research fields.
Objective: To determine the main factors that contribute to the classification of individuals
with higher coronary risk in the adult population from Maracaibo, Venezuela.
Methods: A descriptive, cross-sectional study with multistage random sampling in 1379 individuals
belonging to the Maracaibo City Metabolic Syndrome Prevalence Study (MMSPS) was
performed. They were classified according to the coronary ...
Neurofeedback effects on cognitive performance in children with attention deficit
(Sociedad Venezolana de Farmacología Clínica y Terapéutica, 2018)
The objective of this research was to analyze the effects of
an intervention program through neurofeedback, on the cognitive
performance in children with inattention indicators. A
quasi-experimental pretest-posttest study was used under a
positivist epistemology, with a comparative analysis for each
evaluated cognitive process. A sample of 29 cases was intentionally
selected from a group of children and young adolescents
with low performance indicators from a Therapeutic
Center from Cucuta-Colombia. The neurofeedback program
was developed ...
Fto gene: historic background and its relationship with chronic-degenerative diseasesGene FTO: Aspectos históricos y su relación con enfermedades crónicas no comunicables
(Sociedad Latinoamericana de Hipertención, 2018-07-15)
Alteraciones en el desarrollo de la atención
y la organización conductual pueden
configurar cuadros clínicos como
el trastorno déficit de atención (TDA) que puede estar
acompañado o no de hiperactividad (TDAH), este último
parece tener una relación directa con otros diagnósticos
de tipo endocrino como la obesidad. El objetivo del estudio
es analizar la relación que existe entre el TDAH y la
obesidad. Es por ello que se realiza una revisión sistemática
de estudios científicos revelando relaciones y diferencias
entre ambos trastornos desde ...
Data Mining and Endocrine Diseases: A New Way to Classify?
(Elsevier, 2018-04)
Data mining consists of using large database analysis to detect patterns, relationships and
models in order to describe (or even predict) the appearance of a future event; to accomplish
this, it uses classification methods, rules of association, regression patterns, link and
cluster analyses. Recently this approach has been used to propose a new diabetes mellitus
classification, using information analysis techniques through which the selection bias
minimally influences categorization, this new focus that includes data mining previously
implemented ...
Efecto del consumo de alimentos preparados en el hogar y adquiridos en la escuela sobre el perfil lipídico de escolares en Maracaibo, Venezuela
(Cooperativa servicios y suministros 212518 RS, 2018)
Propósito: En décadas recientes, ha aumentado en la población
infantil la prevalencia de enfermedades como obesidad
y dislipidemias, de manera atribuible a prácticas propias
de la sociedad occidentalizada. Esto incluye sobreingesta
calórica, incluso en el desayuno, una particularmente
importante para ésta demografía. Por lo tanto, el objetivo
de este estudio fue analizar efecto del consumo de alimentos
preparados en el hogar (APH) o alimentos adquiridos en
la institución educativa (AIE) y la ingesta nutricional diaria
en el perfil lipídico ...
Perirenal fat thickness is associated with metabolic risk factors in patients with chronic kidney disease
(The Korean Society of Nephrology, 2019)
Adipose tissue accumulation in specific body compartments has been associated with diabetes, hypertension and dyslipidemia. Perirenal fat (PRF) may lead to have direct lipotoxic effects on renal function and intrarenal hydrostatic pressure. This study was undertaken to explore the association of PRF with cardiovascular risk factors and different stages of chronic kidney disease (CKD). We studied 103 patients with CKD of different stages (1 to 5). PRF was measured by B-mode renal ultrasonography in the distal third between the cortex and the hepatic ...
Is “Leptin Resistance” Another Key Resistance to Manage Type 2 Diabetes?
(Bentham Science Publishers, 2020)
Although novel pharmacological options for the treatment of type 2 diabetes mellitus (DM2) have been observed to modulate the functionality of several key organs in glucose homeostasis, successful regulation of insulin resistance (IR), body weight management, and pharmacological treatment of obesity remain notable problems in endocrinology. Leptin may be a pivotal player in this scenario, as an adipokine which centrally regulates appetite and energy balance. In obesity, excessive caloric intake promotes a low-grade inflammatory response, which ...
Optimal cutoff for the evaluation of insulin resistance through triglyceride-glucose index: A cross-sectional study in a Venezuelan population [version 1; referees: awaiting peer review]
(F1000 Research Ltd., 2017-08-07)
Background: Insulin resistance (IR) evaluation is a fundamental goal in clinical
and epidemiological research. However, the most widely used methods are
difficult to apply to populations with low incomes. The triglyceride-glucose index
(TGI) emerges as an alternative to use in daily clinical practice. Therefore the
objective of this study was to determine an optimal cutoff point for the TGI in an
adult population from Maracaibo, Venezuela.
Methods: This is a sub-study of Maracaibo City Metabolic Syndrome
Prevalence Study, a descriptive, ...
