#1
Ángel Gil, Julio Plaza-Diaz, María Dolores Mesa
BACKGROUND: Classically, vitamin D has been implicated in bone health by promoting calcium absorption in the gut and maintenance of serum calcium and phosphate concentrations, as well as by its action on bone growth and reorganization through the action of osteoblasts and osteoclasts cells. However, in the last 2 decades, novel actions of vitamin D have been discovered. The present report summarizes both classic and novel actions of vitamin D. SUMMARY: 1,25(OH)2 vitamin D, the active metabolite of vitamin D, also known as calcitriol, regulates not only calcium and phosphate homeostasis but also cell proliferation and differentiation, and has a key a role to play in the responses of the immune and nervous systems...

Shprintzen-Goldberg syndrome is a rare systemic connective tissue disorder characterized by craniosynostosis, skeletal abnormalities, infantile hypotonia, mild-to-moderate intellectual disability and cardiovascular anomalies. To our knowledge, this is the first report of a Shprintzen-Goldberg syndrome patient who developed a thoraco-abdominal aortic aneurysm. The aneurysm grew rapidly necessitating emergent thoraco-abdominal aortic replacement. The postoperative course was uneventful, and a careful lifetime follow-up was planned...

This review describes the positive effects of growth hormone (GH) on the cardiovascular system. We analyze why the vascular endothelium is a real internal secretion gland, whose inflammation is the first step for developing atherosclerosis, as well as the mechanisms by which GH acts on vessels improving oxidative stress imbalance and endothelial dysfunction. We also report how GH acts on coronary arterial disease and heart failure, and on peripheral arterial disease, inducing a neovascularization process that finally increases flow in ischemic tissues...

Fibroblast activation protein-α (FAPα) is a promising tumor-associated target expressed by reactive stromal fibroblasts in tumor tissue. FAPα has a postprolyl peptidase activity and can specifically cleave N-terminal benzyloxycarbonyl (Z)-blocked peptides, such as the substrate Z-Gly-Pro-AMC. Doxorubicin (DOX) is an effective antitumor drug, but its application is greatly limited by toxic adverse effects owing to poor tumor selectivity. Based on these facts, we previously designed a FAPα-targeting prodrug of doxorubicin (FTPD) which can be selectively hydrolyzed by FAPα...

Introduction The metabolic syndrome includes a constellation of several well-established risk factors, which need to be aggressively treated in order to prevent overt type 2 diabetes and cardiovascular disease. While recent guidelines for the treatment of individual components of the metabolic syndrome focus on cardiovascular benefits as resulted from clinical trials, specific recent recommendations on the pharmacological management of metabolic syndrome are lacking. The objective of present paper was to review the therapeutic options for metabolic syndrome and its components, the available evidence related to their cardiovascular benefits, and to evaluate the extent to which they should influence the guidelines for clinical practice...

AIMS: Variability in response to Renin-Angiotensin-Aldosterone System (RAAS) inhibition has been shown in clinical trials but its occurrence and impact in clinical practice are unknown. We assessed variability in systolic blood pressure (SBP) and albuminuria (UACR) responses in patients with type 2 diabetes mellitus initiating RAAS inhibition, and assessed the association of response variability with cardiovascular outcomes. METHODS: We performed an observational cohort study in patients with type 2 diabetes who started RAAS inhibition between 2007 and 2013 (n=1600) were identified from general practices in the Netherlands...

Background: Several human studies reported that the combined use of renin-angiotensin system blockers (RASBs) and vitamin D receptor activators (VDRAs) resulted in decreased urinary protein excretion. However, it is unknown whether this combination therapy influences the incidence of cardiovascular (CV) events in dialysis patients. Methods: The study was a multicenter nonrandomized prospective cohort analysis including 1,518 patients. Patients were classified into 4 groups based on medications prescribed before dialysis initiation: those who did not receive RASBs or oral VDRAs (N group), those receiving only RASBs, those receiving only VDRAs, and those receiving a combination of RASBs and VDRAs (RD group)...

Background: A higher risk of atherothrombotic cardiovascular events, which are platelet-driven processes, has been described during acute exacerbations of chronic obstructive pulmonary disease (AECOPD). However, the relevance of platelet reactivity during AECOPD and whether this is affected by antiplatelet agents are not fully elucidated to date. This study aimed to evaluate whether platelet reactivity is augmented during an exacerbation in COPD patients with and without antiplatelet therapy and its association with systemic inflammatory parameters...

BACKGROUND: MicroRNAs (miRNAs) are a key factor in epigenetic regulation of gene expression, but miRNA responses to fine particulate matter (PM2.5) air pollution and their potential contribution to cardiovascular effects of PM2.5 are unknown. OBJECTIVE: We explored the potential influence of PM2.5 on the expression of selected cytokines relevant to systemic inflammation, coagulation, and vasoconstriction, and on miRNAs that may regulate their expression. METHODS: We designed a double-blind, randomized crossover study in which true and sham air purifiers were used to expose 55 healthy young adult students in Shanghai, China, to reduced or ambient levels of indoor PM2...

BACKGROUND: Methylmercury (MeHg) exposure is associated with adverse effects on neurodevelopment and cardiovascular health. Previous work indicates most MeHg is from marine fish sold in the commercial market, but does not fully resolve supply regions globally. This information is critical for linking changes in environmental MeHg levels to human exposure in the U.S. population. OBJECTIVES: We used available data to estimate the geographic origins of seafood consumed in the United States (major ocean basins, coastal fisheries, aquaculture, freshwater) and how shifts in edible supply affected MeHg exposures between 2000-2002 and 2010-2012...

Studies have shown a relationship between maternal periodontal diseases (PDs) and premature delivery. PDs are commonly encountered oral diseases which cause progressive damage to the periodontal ligament and alveolar bones, leading to loss of teeth and oral disabilities. PDs also adversely affect general health by worsening cardiovascular and metabolic diseases. Moreover, maternal PDs are thought to be related to increasing the frequency of preterm-birth with low birth weight (PBLBW) new-borns. Prematurity and immaturity are the leading causes of prenatal and infant mortality and is a major public health problem around the world...

BACKGROUND: Treatment nonadherence and clinical inertia perpetuate poor cardiovascular disease (CVD) risk factor control. Telemedicine interventions may counter both treatment nonadherence and clinical inertia. INTRODUCTION: We explored why a telemedicine intervention designed to reduce treatment nonadherence and clinical inertia did not improve CVD risk factor control, despite enhancing treatment adherence versus usual care. METHODS: In this analysis of a randomized trial, we studied recipients of the 12-month telemedicine intervention...

The use of imaging represents a major impact on the refinement and the reduction of in vivo studies in animal models, in particular for allowing longitudinal monitoring of the onset and the progression of disease within the same animal, and studying the biological effects of drug candidate and their therapeutic effectiveness. But the use of imaging procedures can affect animal physiology, and the need to anesthetize the animals for imaging entails potential health risks. During anesthesia, there is an inevitable autonomic nervous system depression which induces cardiovascular depression, respiratory depression, and hypothermia...

Dobutamine is the inotrope most commonly used in septic shock patients to increase cardiac output and correct hypoperfusion. Although some experimental and clinical studies have shown that dobutamine can improve systemic and regional hemodynamics, other research has found that its effects are heterogenous and unpredictable. In this review, we analyze the pharmacodynamic properties of dobutamine and its physiologic effects. Our goal is to show that the effects of dobutamine might differ between healthy subjects, in experimental and clinical cardiac failure, in animal models and in patients with septic shock...
