Testosterone Therapy for the Treatment of Age-Related Hypogonadism: Risks with Uncertain Benefits.

Testosterone replacement therapy has been approved in the United States since the 1950s for men with "classical" hypogonadism. These men have specific and well-recognized hypothalamic, pituitary, or testicular conditions leading to deficient or absent endogenous testosterone. A more controversial treatment population is aging men, many with comorbidities, who have low serum testosterone concentrations compared with young healthy men and who do not have the well-recognized medical conditions that cause "classical" hypogonadism.

2017 Cardiovascular and Stroke Endpoint Definitions for Clinical Trials.

This publication describes uniform definitions for cardiovascular and stroke outcomes developed by the Standardized Data Collection for Cardiovascular Trials Initiative and the U.S. Food and Drug Administration (FDA).

2017 Cardiovascular and Stroke Endpoint Definitions for Clinical Trials.

This publication describes uniform definitions for cardiovascular and stroke outcomes developed by the Standardized Data Collection for Cardiovascular Trials Initiative and the US Food and Drug Administration (FDA). The FDA established the Standardized Data Collection for Cardiovascular Trials Initiative in 2009 to simplify the design and conduct of clinical trials intended to support marketing applications. The writing committee recognizes that these definitions may be used in other types of clinical trials and clinical care processes where appropriate.

A protocol for active surveillance of acute myocardial infarction in association with the use of a new antidiabetic pharmaceutical agent.

Purpose: To describe a protocol for active surveillance of acute myocardial infarction (AMI) in users of a recently approved oral antidiabetic medication, saxagliptin, and to provide the rationale for decisions made in drafting the protocol.

Methods: A new-user cohort design is planned for evaluating data from at least four Mini-Sentinel data partners from 1 August 2009 (following US Food and Drug Administration's approval of saxagliptin) through mid-2013. New users of saxagliptin will be compared in separate analyses with new users of sitagliptin, pioglitazone, long-acting insulins, and second-generation sulfonylureas.

Impact of cardiovascular outcomes on the development and approval of medications for the treatment of diabetes mellitus.

All medications currently approved by the Food and Drug Administration (FDA) for the treatment of type 2 diabetes mellitus are indicated to improve glycemic control. Since 1995, FDA has used HbA1c as the primary basis for approval of these therapies because a reduction in blood glucose lessens the symptoms of hyperglycemia and lowering of HbA1c has been shown to reduce the risk for some of the chronic complications of diabetes. Despite evidence of clinical benefit with therapies that reduce HbA1c, concerns have been raised that some diabetes medications may increase cardiovascular risk in a patient population that is already vulnerable to cardiovascular disease.

Adrenocortical hormone abnormalities in men with chronic prostatitis/chronic pelvic pain syndrome.

Objectives: To identify adrenocortical hormone abnormalities as indicators of endocrine dysfunction in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).

Methods: We simultaneously measured the serum concentrations of 12 steroids in patients with CP/CPPS and controls, using isotope dilution liquid chromatography, followed by atmospheric pressure photospray ionization and tandem mass spectrometry.

Results: We evaluated 27 patients with CP/CPPS and 29 age-matched asymptomatic healthy controls.

FDA's proactive role in the development of an artificial pancreas for the treatment of diabetes mellitus.

One of the critical path initiatives of the Food and Drug Administration (FDA) is to accelerate the development and availability of a safe and effective artificial pancreas for the treatment of diabetes mellitus. The FDA has established a multidisciplinary group of scientists and clinicians, in partnership with the National Institutes of Health (NIH), to address the clinical, scientific and regulatory challenges related to this unique medical product.:

Beneficial effects of eplerenone versus hydrochlorothiazide on coronary circulatory function in patients with diabetes mellitus.

Context: Impaired coronary circulatory function predicts cardiovascular events, the leading cause of death in patients with diabetes mellitus. Aldosterone causes cardiovascular injury and is not suppressed by chronic angiotensin converting enzyme (ACE) inhibitor therapy.

Objective: Our objective was to assess whether mineralocorticoid receptor activation contributes to coronary circulatory dysfunction in patients with diabetes who are already receiving ACE inhibitor therapy.

Few predictors of massive deep vein thrombosis.

Factors that predispose to thrombus propagation from the femoropopliteal veins to the pelvic veins are poorly understood. Our goal was to determine whether there are characteristics that identify patients with massive deep vein thrombosis (DVT). We compared the 122 (2.

Sex hormone-binding globulin and serum testosterone are inversely associated with C-reactive protein levels in postmenopausal women at high risk for cardiovascular disease.

Purpose: C-reactive protein (CRP), androgens, and menopausal loss of endogenous estrogens are associated with cardiovascular disease (CVD). We hypothesized that high androgens, low estradiol, and low sex hormone-binding globulin (SHBG) would be associated with high CRP in postmenopausal women.

Methods: CRP, SHBG, estradiol, and total testosterone were measured using baseline bloods of 221 hormone therapy (HT)-nonusers and 162 HT-users from a cross-sectional analysis in a nested case-control sample of the Women's Health Study.

Effect of aldosterone and mineralocorticoid receptor blockade on vascular inflammation.

Aldosterone, the final product of the renin-angiotensin-aldosterone system, is classically viewed as a regulator of renal sodium and potassium handling, blood volume, and blood pressure. Recent studies suggest that aldosterone can cause microvascular damage, vascular inflammation, oxidative stress and endothelial dysfunction. In animal models, aldosterone-mediated vascular injury in the brain, heart, and kidneys leads to stroke, myocardial injury, and proteinuria.

Upper-extremity deep vein thrombosis: a prospective registry of 592 patients.

Background: Upper-extremity deep vein thrombosis (UEDVT) occurs spontaneously or sometimes develops as a complication of pacemaker use, long-term use of a central venous catheter (CVC), or cancer.

Methods And Results: To improve our understanding of UEDVT, we compared the demographics, symptoms, risk factors, prophylaxis, and initial management of 324 (6%) patients with central venous catheter (CVC)-associated UEDVT, 268 (5%) patients with non-CVC-associated UEDVT, and 4796 (89%) patients with lower-extremity DVT from a prospective US multicenter DVT registry. The non-CVC-associated UEDVT patients were younger (59.

Warfarin dosing and cytochrome P450 2C9 polymorphisms.

Two cytochrome P450 2C9 (CYP2C9) polymorphisms, CYP2C9*2 and *3, metabolize warfarin inefficiently. We assessed the extent to which these polymorphisms explain very low warfarin dose requirements and hemorrhagic complications after excluding non-genetic determinants of warfarin dosing. In this retrospective observational study, 73 patients with stable warfarin doses for > or =1 month and International Normalized Ratios (INR) of 2.

Laboratory thrombophilias and venous thromboembolism.

Inherited abnormalities of coagulation are increasingly recognized in patients with venous thromboembolism. Common causes of hypercoagulability, also known as thrombophilia, include factor V Leiden, the prothrombin gene mutation, hyperhomocysteinemia, and antiphospholipid antibodies. Thrombophilia should be suspected in patients who develop idiopathic venous thromboembolism at a young age, recurrent thrombosis, thromboses at unusual sites, recurrent unexplained pregnancy loss, or if there is a family history of thrombotic disorders.
