¿Existe asociación entre asma y adiposidad en la población adulta chilena?

Rev. méd. Chile; 147 (6), 2019
Background: In people with asthma, adiposity is associated with more symptoms and less control of the disease whereas on those without asthma adiposity is associated with a higher risk of developing the disease. Aim: To investigate the association between asthma and adiposity markers in Chilean adults. ...

Estandarización de la fuerza de prensión manual en adultos chilenos sanos mayores de 20 años

Rev. méd. Chile; 147 (6), 2019
Background: A low hand grip strength is a prognostic factor both in healthy people and hospitalized subjects. Local normal hand grip strength values are needed to define cutoff points of abnormality. Aim: To measure handgrip strength in Chilean people aged 20 to 70 years and propose normal values for he...

Determinación de intervalos biológicos de referencia para adultos en el equipo hematológico BC-5000 de la Escuela de Microbiología de la Universidad de Antioquia, Medellín 2017

Iatreia; 32 (2), 2019
RESUMEN Introducción: los valores del hemograma en adultos pueden variar de acuerdo con factores como el origen étnico, la edad, el sexo y la altura sobre el nivel del mar, por lo cual es indispensable conocer intervalos biológicos asociados a nuestra población. Por esto el objetivo de nuestro estu...

Does obesity affect intraocular pressure during laparoscopic surgery?

Arq. bras. oftalmol; 82 (3), 2019
ABSTRACT Purpose: Obesity is accepted as a risk factor for postoperative visual loss due to possible perioperative elevations in intraocular pressure. This study investigated whether intraocular pressure changes differed according to the body mass index of patients undergoing laparoscopic cholecystectom...

Intraocular pressure in subjects with beta-thalassemia minor

Arq. bras. oftalmol; 82 (3), 2019
ABSTRACT Purpose: Beta-thalassemia minor, a common hereditary blood disorder in Mediterranean countries such as Turkey, is associated with insulin resistance. Insulin resistance, in turn, can be associated with excessively high intraocular pressure and, therefore, intraocular pressure-induced blindness....

Association between Chagas disease and changes in the optic nerve and retinal nerve fiber layer

Arq. bras. oftalmol; 82 (3), 2019
ABSTRACT Purpose: To test the hypothesis that Chagas disease predisposes to optic nerve and retinal nerve fiber layer alterations. Methods: We conducted a cross-sectional study including 41 patients diagnosed with Chagas disease and 41 controls, paired by sex and age. The patients underwent ophthalmolo...

Lack of association between provocative test-based intraocular pressure parameters and functional loss in treated glaucoma patients

Arq. bras. oftalmol; 82 (3), 2019
ABSTRACT Purpose: To correlate provocative test-based intraocular pressure (IOP) variation parameters (fluctuation and peak) with functional status, and to compare these IOP parameters between treated eyes with asymmetric primary open-angle glaucoma (POAG). Methods: A prospective observational study in...

Multisectorial changes in the ciliary muscle during accommodation measured with high-resolution optical coherence tomography

Arq. bras. oftalmol; 82 (3), 2019
ABSTRACT Purpose: To measure changes in the anterior ciliary muscle during accommodation at the nasal, superior, temporal, and inferior sectors by means of an anterior chamber optical coherence tomographer, and correlate them with vergence changes. Methods: Twenty-four subjects with healthy, phakic eye...

Objective evaluation of vision quality in pseudophakic patients with posterior capsular opacification using double-pass retinal imaging

Arq. bras. oftalmol; 82 (3), 2019
ABSTRACT Purpose: The purpose of this study was to objectively assess the optical vision quality of patients before and after Nd:YAG capsulotomy for posterior capsular opacification using a double-pass retinal imaging system. Methods: We retrospectively analyzed the data from 26 pseudophakic eyes with ...

Sex-divided reference intervals for mean platelet volume, platelet large cell ratio and plateletcrit using the Sysmex XN-10 automated haematology analyzer in a UK population

ABSTRACT Background: This study aimed to define the sex-divided reference intervals for platelet indices (mean platelet volume (MPV), platelet distribution width (PDW), platelet large cell ratio (P-LCR) and plateletcrit (PCT)) on the Sysmex XN-10. Methods: A total of 2376 samples were assayed for full ...
