BACKGROUND: Acute hyponatremia is a medical emergency which confers high mortality, attributed primarily to cerebral edema. Expert guidelines advocate the use of intravenous boluses of hypertonic saline, rather than traditional continuous infusion, in order to achieve a faster initial rise in plasma sodium concentration. However, there is a limited evidence base for this recommended policy change. METHODS: We prospectively assessed the clinical and biochemical outcomes in patients treated for symptomatic hyponatremia due to syndrome of inappropriate antidiuresis (SIAD), in response to intravenous bolus treatment with 3% saline (100ml, repeated up to two more times), and compared the outcomes to retrospective data from patients treated with continuous intravenous infusion of low dose (20ml/hour) 3% saline...

CONTEXT: xytocin (OT) and vasopressin share anatomical pathways of synthesis and secretion, and patients with central diabetes insipidus (CDI) are presumably at risk for OT deficiency. However, an oxytocin-deficient state in hypopituitary patients has not been established. OBJECTIVES: We hypothesized that in men with CDI compared to (1) patients with similar anterior pituitary deficiencies but no CDI (APD) and (2) healthy controls (HC) of similar age and BMI, plasma OT levels would be lower and associated with increased psychopathology...

OBJECTIVES: The understanding of the mechanisms underlying thyroid cancer immune escape can lead to the identification of new molecular targets and/or efficacy biomarkers. For this purpose, we performed immune expression profiling in thyroid cancers to obtain a comprehensive view on immune mechanisms activated during cancer progression. METHODS: The study was conducted retrospectively in 25 papillary thyroid carcinomas (PTC), 14 poorly differentiated thyroid carcinomas (PDTC), 13 anaplastic thyroid carcinomas (ATC) and 7 normal thyroid tissue samples (NT)...

OBJECTIVE: changes in bile flow after bariatric surgery may beneficially modulate secretion of insulin and incretins leading to diabetes remission. However, the exact mechanism(s) involved are still unclear. We here propose an alternative method to investigate the relation between alterations in physiological bile flow and insulin and incretin secretion by studying the changes in gut-pancreatic function in extrahepatic cholestasis in non-diabetic humans. METHODS: to pursue this aim, 58 non-diabetic patients with recent diagnosis of periampullary tumors underwent an OGTT, and a subgroup of 16 patients also underwent 4-hour mixed meal tests and hyperinsulinemic euglycemic clamps...

INTRODUCTION: Pegvisomant (PEG) in monotherapy or combined with somatostatin analogs (SSAs) is used to control acromegaly, improving metabolism. However, the metabolic changes induced by PEG have not been systematically reviewed. OBJECTIVE: To address the following questions: Does 1) PEG or 2) the combination of PEG and SSAs affect fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1c), glucose load (2h-OGTT), insulin levels (FPI), homeostatic model assessment of insulin resistance and β-cell function (HOMA-I and HOMA-β), triglycerides (TGDs), total cholesterol, HDL-cholesterol, LDL-cholesterol or body mass index? 3) Are the effects disease-related or drug-related? DATA SOURCES: Indexed databases up to January 2019...

CONTEXT: For decades, there has been epidemiologic evidence linking chronic toxic metal exposure with cardiovascular disease, suggesting a therapeutic role for metal chelation. Given the lack of compelling scientific evidence however, the indications for metal chelation were never clearly defined. To determine the safety and efficacy of chelation therapy, the National Institutes of Health funded the Trial to Assess Chelation Therapy (TACT). TACT was the first double blind, randomized, controlled trial to demonstrate an improvement in cardiovascular outcomes with edetate disodium therapy in patients with prior myocardial infarction...
