ABSTRACT

Objetivo investigar a correlação da circunferência do pescoço com outros parâmetros antropométricos, com a pressão arterial, com a glicemia capilar e com fatores de risco modificáveis e não modificáveis presentes. Método estudo transversal descritivo, com pacientes de uma policlínica, mediante aplicação de questionário semiestruturado. Circunferência do pescoço aferida considerando posição natural da cabeça, entre ponto médio cervical e do pescoço anterior. Risco cardiovascular determinado pela medida da circunferência abdominal e pelos fatores de risco modificáveis ou não modificáveis. Resultados encontradas correlações positivas entre circunferência do pescoço e índice de massa muscular, circunferência abdominal, pressão arterial sistólica, glicemia capilar e idade, além de ter sido identificado alto risco cardiovascular na maioria dos participantes do sexo masculino, com tendência de medida ser maior em indivíduos com hipertensão, diabetes e dislipidemias. Conclusão circunferência do pescoço correlacionou-se significativamente com índice de massa corpórea, circunferência abdominal, pressão sistólica, glicemia capilar e idade.

Objective to investigate the correlation of neck circumference with other anthropometric parameters, with blood pressure, capillary glycemia and with modifiable and non-modifiable risk factors present. Method descriptive cross-sectional study, with patients from a polyclinic, by applying a semi-structured questionnaire. Neck circumference was measured considering the natural position of the head, between cervical midpoint and anterior neck. Cardiovascular risk was determined by measurement of abdominal circumference and modifiable or non-modifiable risk factors. Results positive correlations were found between neck circumference and muscle mass index, abdominal circumference, systolic blood pressure, capillary glycemia and age, besides identifying high cardiovascular risk in most male participants, with a tendency to be higher in individuals with hypertension, diabetes and dyslipidemias. Conclusion neck circumference was significantly correlated with body mass index, abdominal circumference, systolic pressure, capillary glycemia and age.

ABSTRACT

RESUMEN Introducción: El perímetro de cuello en la actualidad es una medida útil asociada de manera significativa a la resistencia a la insulina y al riesgo cardiometabólico. Objetivo: Determinar la relación entre el perímetro de cuello y los factores de riesgo cardiometabólico en mujeres de 45 a 60 años de edad. Métodos: Se realizó un estudio en 270 mujeres aparentemente sanas, de 45 a 60 años de edad. Se tomaron medidas antropométricas como peso corporal, índice de masa corporal, perímetro de cintura, perímetro de cuello y el tejido adiposo visceral por bioimpedancia. Se determinaron niveles séricos de glucosa, perfil lipídico (colesterol, triglicéridos, HDL-colesterol, LDL-colesterol), HbA1c, insulina y proteína C reactiva. Resultados: El índice de masa corporal de las participantes fue de 28,2 ± 4,2. Se encontró que 38,1 por ciento de las mujeres presentaban síndrome metabólico y mayor perímetro de cuello, en comparación con las participantes sin síndrome (36,8 + 2,1 vs 35,1 + 1,6 cm, respectivamente, p< 0,0001). El perímetro de cuello se asoció positivamente con índice de masa corporal (r= 0,690, p= 0,0001), tejido adiposo visceral (r= 0,548, p= 0,0001), circunferencia de Cintura (r= 0,640, p< 0,0001), glucosa (r= 0,251, p= 0,0001), triglicéridos (r= 0,143, p= 0,019), HbA1c (r= 0,160, p= 0,010) y proteína C reactiva (r= 0,342, p= 0,001). Conclusiones: Las mujeres con incremento en el perímetro de cuello presentan un perfil de riesgo cardiometabólico aumentado. La medición del perímetro de cuello representa un método útil y práctico en la predicción del riesgo cardiometabólico(AU)


ABSTRACT Introduction: Neck´s perimeter is nowadays a useful measure significantly associated to insulin resistance and to cardiometabolic risk. Objective: To determine the relation between the neck´s perimeter and the cardiometabolic risk factors in women from 45 to 60 years old. Methods: A study was performed in 270 apparently healthy women, aging 45 to 60 years old. Anthropometric measurements were taken such as weight, body mass index, waist circumference, neck´s perimeter and visceral adipose tissue by bioelectrical impedance analysis. There were identified serum levels of glucose, lipid profile (cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol), HbA1c, insulin and C-reactive protein. Results: The body mass index of the participants was 28.2 ± 4.2. It was found that 38.1 percent of the women had a metabolic syndrome and a higher perimeter of neck, in comparison with participants without the syndrome (36.8 + 2.1 vs 35.1 + 1.6 cm, respectively, p< 0.0001). The neck´s perimeter was positively associated with body mass index (r = 0.690, p= 0.0001), visceral adipose tissue (r = 0.548, p= 0.0001), waist circumference (r = 0.640, p< 0.0001), glucose (r = 0.251, p= 0.0001), triglycerides (r = 0.143, p = 0.019), HbA1c (r = 0.160, p = 0.010) and C-reactive protein (r = 0.342, p = 0.001). Conclusions: Women with an increase in the neck´s perimeter have a profile of increased cardiometabolic risk. The measurement of neck´s perimeter represents a useful and practical method for the prediction of cardiometabolic risk(AU)

ABSTRACT

El desarrollo embrionario de las regiones facial, del cuello, cavidades nasales y oral en conjunto con las glándulas asociadas, involucra el crecimiento y fusión tridimensional de múltiples procesos. Existe participación de elementos derivados de las 3 capas embrionarias locales y adicionalmente de células derivas de la cresta neural, procedentes de los rombómeros vecinos. Estas últimas se ven involucradas en la formación del esqueleto local, entre otras estructuras. El estudio evolutivo desde los vertebrados sin mandíbula nos enseña como se expresan los genes Hox en las diferentes especies, y como esto determina la formación de diferentes estructuras. En la siguiente revisión contemplamos algunos aspectos morfológicos, moleculares y evolutivos básicos del desarrollo facial y cervical, con énfasis en mamíferos con un epílogo referente a las malformaciones de la región en humanos.


The embryonic development of the facial area, neck, nasal, oral and pharyngeal cavities with glands, involves growth and fusion of multi-dimensional processes. There is involvement of elements from the embryo-derived local 3 layers cells further neural crest derived cells from the neighbors rhombomeres. The neural crest cells are involved in the formation of local skeleton, among other structures. The study of evolution from jawless vertebrates shows us how Hox genes are expressed in different species, and how this determines the formation of different structures. The following review contemplate some morphological, molecular and evolutionary basis of facial and neck development, with emphasis on mammals with an epilogue concerning to the face and neck malformations in humans.

ABSTRACT

In this manuscript the thyroid is described by a new model. Efficiencies of a NaI(Tl) detector, for 364 keV photons, are calculated using Monte Carlo simulation. Contributions from thyroid size, detector placement and tissue overlay thickness, to the efficiency uncertainty, are evaluated considering the thyroid of a 12 year old subject as a limit for the adult thyroid. For a shielded 3" x 3" NaI(Tl) detector, placed at 20 cm from the neck, a contribution of 18% to the efficiency uncertainty was found.
