Heart rate variability and perception of mental stress among medical students and residents at an emergency department.

Background: When Medical Residents (MR) and Medical Students (MS) are assigned to the demanding environment of an Emergency they inevitably encounter stress. The aims of this study are to measure short-term heart rate variability (HRV) before and after shifts, estimate perceived stress levels, and assess the recovery patterns after their shifts.

Methods: We assessed HRV parameters in MS and MR using the wristband physiological monitor Polar® Verify Sense before and after day (DS) and night shifts (NS).

Residual C-peptide in patients with Type 1 diabetes and multiethnic backgrounds.

Objective: To evaluate serum C-peptide in 88 patients from a multiethnic population with Type-1 diabetes and variable disease durations.

Method: Eighty-eight patients with a mean disease duration of 8.1 +7.

[GADA persistence and detectable C peptide in patients with long standing diabetes mellitus type 1].

Objective: The aim of this study was to evaluate if GADA+ and detectable CP had any influence in other autoimmune diseases, glycemic control, and risks of retinopathy in diabetes mellitus type 1 (T1DM) lasting longer than 3 years of duration.

Subjects And Methods: Fifty T1DM subjects were interviewed, performed fundoscopic examination, and measured CP before and after glucagon, HbA1C, and GADA.

Results: GADA+ (n = 17) had a higher frequency of other autoimmune diseases when compared to GADA (p = 0.

Management of prolactinomas in Brazil: an electronic survey.

Dopamine agonists are the treatment of choice for prolactinomas. However, there are still controversies concerning dose, treatment duration and criteria for drug withdrawal in different clinical situations. The aim of this study was to assess diagnostic and therapeutic approaches to prolactinomas among members of the Brazilian Society of Endocrinology and Metabolism (SBEM).
