OBJECTIVE: To discuss the recent literature on paternal obesity, focusing on the possible mechanisms of transmission of the phenotypes from the father to the children. SOURCES: A non-systematic review in the PubMed database found few publications in which paternal obesity was implicated in the adverse transmission of characteristics to offspring. Specific articles on epigenetics were also evaluated. As the subject is recent and still controversial, all articles were considered regardless of year of publication...

OBJECTIVE: Although blood pressure (BP) is a major determinant of arterial stiffness, whether high pulse wave velocity (PWV) adversely influences cardiac parameters and cardiovascular (CV) outcome in patients without high BP remains unclear. METHODS: Outpatients without high BP (n=320), defined as systolic BP ≥140 mm Hg, were enrolled in this retrospective study. At baseline, all patients underwent echocardiography and multidetector CT to determine the coronary artery calcification (CAC) score...

Lead exposure is increasingly becoming an important risk factor for osteoporosis. In adults, approximately 80-90 % of absorbed lead is stored in the bones. These bone lead deposits are released into the blood during periods of enhanced bone resorption like menopause, forming a potential endogenous source of lead exposure. Postmenopausal women are at a higher risk for bone lead release because of hormonal and age related changes in bone metabolism. Estrogen deficiency is associated with increase in osteoclasts number and activity leading to both the early and late form of osteoporosis...

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disorder in industrialized countries and is associated with increased risk of cardiovascular, hepatic and metabolic diseases. Molecular mechanisms on the root of the disrupted lipid homeostasis in NAFLD and potential therapeutic strategies can benefit of in vivo and in vitro experimental models of fatty liver. Here, we describe the high fat diet (HFD)-fed rat in vivo model, and two in vitro models, the primary cultured rat fatty hepatocytes or the FaO rat hepatoma fatty cells, mimicking human NAFLD...

PURPOSE: Acromegaly is a rare disease generally brought about by a benign tumour in the pituitary and characterized by growth hormone (GH) and insulin-like growth factor 1 (IGF-1) excess. Increased mortality has been related to cardiovascular events that could be linked to these hormones and patients suffer from high rates of diabetes and hypertension. In this study, we examine if the incidence of myocardial infarction (MI) and stroke differ from that of the general population. METHODS: Data from the German Acromegaly Registry in seven specialized endocrine centres were analysed (n = 479, 56% female, 46 years old at diagnosis, 5549 person-years from diagnosis)...

BACKGROUND: Ecdysteroids, a group of steroid hormones found in insects and many plants, have been shown to prevent various changes in mammalian tissues after female sex hormone deprivation. PURPOSE: To examine whether an ecdysteroid, 20-hydroxyecdysone (20-HE), exhibits regulatory or protective roles in the cardiovascular system. STUDY DESIGN/METHOD: Blood pressure and cardiac function were evaluated in spontaneously hypertensive rats (SHR) during and after daily treatment with 20-HE for six weeks...

The worlds of observational, clinical and basic science collided in 2002 with the publication of results of the Women's Health Initiative (WHI), a large scale, prospective, blinded, randomized-controlled trial designed to provide evidence regarding use of hormone treatment to prevent cardiovascular disease in menopausal women. The results of the WHI dramatically changed clinical practice, negatively impacted funding for hormone research and left scientists to unravel the "why" of the results. Now over a decade and a half since the initial publication of the WHI results, basic and clinical scientists often do not interpret the results of the WHI with the precision needed to move the science forward...

BACKGROUND: Vascular calcification is common among patients with chronic kidney disease (CKD), and it is associated with all-cause and cardiovascular disease mortality. Deoxycholic acid, a metabolite of circulating bile acids, is elevated in CKD and induces vascular mineralization and osteogenic differentiation in animal models. STUDY DESIGN: Cohort analysis of clinical trial participants. SETTING & PARTICIPANTS: 112 patients with moderate to severe CKD (estimated glomerular filtration rate, 20-45mL/min/1...

The mechanisms of vascular alterations resulting from early thyroid hormones deficiency are poorly understood. We tested the hypothesis that antenatal/early postnatal hypothyroidism would alter the activity of endothelial NO-pathway and Rho-kinase pathway, which are specific for developing vasculature. Dams were treated with propylthiouracil (PTU, 7 ppm) in drinking water during gestation and 2 weeks after delivery, their progeny had normal body weight but markedly reduced blood levels of thyroid hormones (ELISA)...

According to life history theory, increased investment in reproductive function (physiology and behaviour) at different times throughout the life course affects the risk of many diseases and, ultimately, longevity. Although genetic factors contribute to interindividual and interpopulation variation in reproductive traits, the dominant source of variability is phenotypic plasticity during development and adult life. Reproductive traits in both sexes evolved sensitivity to ecological conditions, as reflected in contemporary associations of hormone concentrations with geographical setting, nutritional status, and physical activity level...

RATIONALE: Given that the diagnosis of primary hyperparathyroidism (PHPT) is given at an increasingly less-symptomatic phase, and the literature data on the cardiovascular risk of patients with normocalcemic primary hyperparathyroidism (NPHPT) are controversial, the coronary calcium score (CCS), which is correlated with coronary artery disease, may be useful for clarifying the association between cardiovascular risk and NPHPT. OBJECTIVE: This research aims to describe the CCS and the clinical and laboratory variables of patients with NPHPT compared with a control group and to verify the presence of an association between NPHPT and CCS...

The focus of this edition of Clinical Pharmacolgoy & Therapeutics (CPT) is on drugs and renal function and will not include a detailed discussion of kidney disease and its treatment. It is well recognized that drugs affect the kidneys in different ways, while kidney disease impacts drug metabolism and response. It is impossible to underestimate the value of the kidneys to man in health and disease, from regulation of fluid and electrolyte balance to participating in drug metabolism and transport. Additionally, the kidneys serve as targets for drugs used to treat cardiovascular (CV) diseases including hypertension and heart failure, metabolic diseases such as diabetes mellitus and obesity, chronic kidney disease (CKD), as well as playing a role in the regulation of several hormones...

Thyroid diseases are closely associated with the development of types 1 and 2 diabetes mellitus (DM), and as a consequence, the development of effective approaches for their treatment is one of the urgent problems of endocrinology. Traditionally, thyroid hormones (TH) are used to correct functions of the thyroid system. However, they are characterized by many side effects, such as their negative effect on the cardiovascular system as well as the ability of TH to enhance insulin resistance and to disturb insulin-producing function of pancreas, exacerbating thereby diabetic pathology...

Leptin is an endocrine hormone that has a critical role in body weight homoeostasis and mediates its effects via the leptin receptor (LEPR). Common polymorphisms in the genes coding leptin receptors have been associated with metabolic abnormalities. We assessed the association of 28 LEPR polymorphisms with body mass index (BMI) and their relationship with obesity-related phenotypes, inflammation and cardiovascular disease risk biomarkers. A multicentre case-control study was conducted in 522 children (286 with obesity and 236 with normal-BMI)...

Vitamin D is a fat-soluble secosteroid hormone with pleiotropic effects. 1,25-Dihydroxyvitamin D coordinates the biosynthesis of neurotransmitters in the central nervous system, which regulate cardiovascular autonomic function and may explain its putative role in the development of cardiovascular autonomic neuropathy (CAN). CAN is an independent risk factor for mortality in patients with diabetes and prediabetes and is associated with an increased risk of developing type 2 diabetes and cardiovascular disease...

AIM: We assessed the longitudinal association between tooth loss and peripheral arterial disease (PAD) within the Nurses' Health Study. MATERIALS AND METHODS: After excluding participants with prior cardiovascular diseases, 277 out of 79,680 women were confirmed as PAD cases during 16-years of follow-up. Number of teeth and recent tooth loss were reported initially in 1992. Subsequent tooth loss was recorded in 1996 and in 2000. We evaluated the associations of baseline number of teeth and recent tooth loss with risk of PAD, adjusting for age, smoking, diabetes, hypertension, high cholesterol, aspirin use, family history of myocardial infarction, BMI, alcohol consumption, physical activity, post-menopausal hormone use, and use of vitamin E, vitamin D, multivitamin, and calcium...

Many traditional cardiovascular hormones have been implicated in metabolic function. Conversely, many hormones traditionally involved in metabolic regulation have an effect on cardiovascular function. Many of these signalling molecules exert such effects through specific actions in the paraventricular nucleus (PVN), an integrative autonomic control centre located in the hypothalamus. Here, we focus on four cardiovascular/metabolic peptide hormones that signal within the PVN, angiotensin II, orexin, adiponectin, and nesfatin-1...

It is known that autonomic modulation is responsive to ovarian hormone levels and that estrogen increases nitric oxide (NO) bioavailability. However, little is known about the interaction of nitric oxide synthase (NOS) isoforms with autonomic modulation, oxidative stress and cardiovascular risk in females. This study aimed to investigate cardiovascular, autonomic and oxidative parameters after selective NOS inhibition. A spectral analysis of systolic arterial pressure (SAP) and heart rate variability (HRV) was performed...

BACKGROUND: Low thyroid hormone (TH) levels and myocardial damage are common in dialysis patients and are associated with mortality. However, little is known about the role of THs on myocardial damage as has been described in primary thyroid diseases. The aim of this study was to explore the potential relationship between low total triiodothyronine (total T3) and biomarkers of myocardial damage and the effect of their interaction on mortality, to ascertain if cardiovascular damage is the link between low THs and the risk of death in dialysis patients with CKD...
