Arq. bras. oftalmol; 79 (4), 2016
ABSTRACT Purpose: The objective of this study was to evaluate subfoveal choroidal thickness (SFCT) using enhanced depth imaging optical coherence tomography (EDI-OCT) in patients with naïve branch retinal vein occlusion (BRVO) before and after intravitreal dexamethasone implant (Ozurdex®) injection. ...

Oxidative stress of crystalline lens in rat menopausal model

Arq. bras. oftalmol; 79 (4), 2016
ABSTRACT Purpose: To evaluate lenticular oxidative stress in rat menopausal models. Methods: Forty Wistar female albino rats were included in this study. A total of thirty rats underwent oophorectomy to generate a menopausal model. Ten rats that did not undergo oophorectomy formed the control group (Gr...

Economic evaluation of the new oral anticoagulants for the prevention of thromboembolic events: a cost-minimization analysis

Säo Paulo med. j; 134 (4), 2016
ABSTRACT CONTEXT AND OBJECTIVE: Randomized clinical trials have shown that the new oral anticoagulants have at least similar impact regarding reduction of thromboembolic events, compared with warfarin, with similar or improved safety profiles. There is little data on real costs within clinical practice...

Air pollution and respiratory diseases: ecological time series

Säo Paulo med. j; 134 (4), 2016
ABSTRACT CONTEXT AND OBJECTIVE: Exposure to air pollutants is one of the factors responsible for hospitalizations due to respiratory diseases. The objective here was to estimate the effect of exposure to particulate matter (such as PM2.5) on hospitalizations due to certain respiratory diseases among re...

Subjective visual vertical with the bucket method in Brazilian healthy individuals

ABSTRACT INTRODUCTION: The capacity of a healthy individual to estimate the true vertical in relation to the Earth when a fluorescent line is aligned in a completely dark room is called the subjective visual vertical. OBJECTIVE: To evaluate subjective visual vertical using the bucket method in health...

Primary Hyperparathyroidism: The Influence of Bone Marrow Adipose Tissue on Bone Loss and of Osteocalcin on Insulin Resistance

Clinics; 71 (8), 2016
OBJECTIVES: Bone marrow adipose tissue has been associated with low bone mineral density. However, no data exist regarding marrow adipose tissue in primary hyperparathyroidism, a disorder associated with bone loss in conditions of high bone turnover. The objective of the present study was to investigate ...
