Association of Serum Thyroxine and Atrial Fibrillation in Patients on Levothyroxine.

Introduction: Excess thyroid hormone is a well-documented risk factor for the development of atrial fibrillation (AF). The purpose of the study is to assess incidence of AF in patients taking levothyroxine for hypothyroidism and correlate it with biochemical thyroid function.

Materials And Methods: This was a retrospective cohort study of patients aged 18 years and older who were treated with levothyroxine.

Using Contact-Based Education to Reduce Diabetes-Related Stigma Among Medical Residents in a Military Health System.

Introduction: Healthcare provider-related stigma against patients with diabetes is associated with worse doctor-patient relationships and patient self-care. A previous feasibility study showed benefit in using a contact-based education approach to improve attitudes of medical students toward patients with diabetes. We hosted a panel of people who had personal experience with diabetes.

Neutral effect of exenatide on serum testosterone in men with type 2 diabetes mellitus: A prospective cohort.

Background: Endogenous testosterone increases with weight loss from diet, exercise, and bariatric surgery. However, little is known about testosterone levels after weight loss from medication.

Objectives: Uncover the effects of Glucagon-Like Peptide-1 receptor agonist (GLP-1 RA) therapy on serum testosterone.

Adrenal Adenoma Anarchy: A Case of an ACTH-Secreting Pheochromocytoma.

. Pheochromocytomas are rare neuroendocrine tumors that arise from sympathetic adrenomedullary chromaffin tissue. Depending on the amount of catecholamines they secrete, they have variable presentations.

IMPACT OF STRUCTURED INSULIN ORDER SETS ON INPATIENT HYPOGLYCEMIA AND GLYCEMIC CONTROL.

In hospitalized patients, glycemic excursions outside recommended glycemic targets have been associated with increased morbidity and mortality. Despite recommendations to avoid use of correctional insulin alone for managing hyperglycemia, this approach remains common. We performed a quality improvement project aimed at both reducing hypoglycemic events and promoting increased use of basal insulin by updating our insulin order sets to reflect clinical practice guideline recommendations.

Transient Central Diabetes Insipidus after Discontinuation of Vasopressin.

Central diabetes insipidus (CDI) is an uncommon condition resulting from lack of vasopressin secretion from the posterior pituitary gland typically caused by some form of destruction of the gland. Here we present a case of transient CDI after discontinuation of vasopressin used for septic shock without evidence of overt pituitary damage. Serum sodium concentration peaked at 160 mmol/L in the setting of polyuria within days of vasopressin discontinuation without identified alternative etiologies.

Analysis of current thyroid function test ordering practices.

Rationale: Current guidelines recommend thyroid stimulating hormone (TSH) alone as the best test to detect and monitor thyroid dysfunction, yet free thyroxine (FT4) and free triiodothyronine (FT3) are commonly ordered when not clinically indicated. Excessive testing can lead to added economic burden in an era of rising healthcare costs, while rarely contributing to the evaluation or management of thyroid disease.

Objective: To evaluate our institution's practice in ordering thyroid function tests (TFTs) and to identify strategies to reduce inappropriate FT4 and FT3 testing.

Effect of magnesium chloride on psychomotor activity, emotional status, and acute behavioural responses to clonidine, d-amphetamine, arecoline, nicotine, apomorphine, and L-5-hydroxytryptophan.

Background: The beneficial effects of magnesium (Mg) salts on central manifestations of Mg deficiency are well known. Mg replacement therapy can be effective to prevent some of the serious depression-like and anxiety-related behaviour sequelae of Mg deficiency. However, few experimental studies have been undertaken on Mg-deficiency-induced behavioural changes.
