INTRODUCTION: Pulmonary embolism (PE) is a life threatening preventable medical condition involving sudden occlusion of arteries within the lungs. Systemic lupus erythematosus (SLE) is an inflammatory disorder and therefore independently poses a risk of PE. We aimed to determine the association of SLE and PE using National Hospital Discharge Survey data, a national representative sample of hospital discharges throughout the United States. METHODS: Retrospective population-based analysis was done using National Hospital Discharge Survey data for the period 2001 to 2010...

BACKGROUND: Psoriasis, atopic dermatitis or eczema (AD-E), pemphigus, bullous pemphigoid (BP), and hidradenitis are chronic inflammatory skin disorders associated with systemic immune activation, considerable symptom burden, stigma, functional disturbances, and mental health symptoms. All of these might increase cardiovascular risk. OBJECTIVE: The objective of this study was to determine whether these inflammatory skin diseases are associated with increased cardiovascular/cerebrovascular risk and/or disease...

OBJECTIVE: The aim of this study was to evaluate the association between prenatally diagnosed isolated single umbilical artery (iSUA) and perinatal outcomes. METHODS: We searched Medline, Embase, the Cochrane Library, and KoreaMed from inception to January 2016, with no language or regional restrictions, for cohort and case-control studies reporting on the relationship of iSUA and perinatal outcomes. We assessed the odds ratios (ORs) and 95% confidence intervals (CIs) for the occurrence of small for gestational age, preterm birth, pregnancy-induced hypertension, neonatal intensive care unit admission, and perinatal mortality in fetuses with iSUA compared with those in fetuses with three vessel cord...

Incontinentia pigmenti (IP; Bloch-Sulzberger syndrome) is a rare, genetic syndrome inherited as an X-linked dominant trait. It primarily affects female infants and is lethal in the majority of males during fetal life. The clinical findings include skin lesions, developmental defects, and defects of the eyes, teeth, skeletal system, and central nervous system. Cardiovascular complications of this disease in general, and pulmonary hypertension in particular, are extremely rare. This report describes the case of a 3-year-old girl with IP complicated by pulmonary arterial hypertension...

Experimental or spontaneous genomic mutations of the renin-angiotensin system or its pharmacological inhibition in early life leads to renal abnormalities, including poorly developed renal medulla, papillary atrophy, hydronephrosis, inability to concentrate the urine, polyuria, polydipsia, renal failure, and anemia. At the core of such complex phenotype is the presence of unique vascular abnormalities: the renal arterioles do not branch or elongate properly and they have disorganized, concentric hypertrophy...

CYP11B2 is a key enzyme involved in the synthesis of the mineralocorticoid aldosterone. CYP11B2 expression in the adrenal glands is controlled by the renin-angiotensin system (RAS), and plays an important role in the maintenance of electrolyte metabolism in higher organisms. Abnormal overexpression of CYP11B2 results in the disruption of mineral balance and can lead to hypertension. Though the molecular mechanism of the regulation of CYP11B2 expression has remained elusive, we hypothesize that compounds that prevent CYP11B2 expression could represent a novel class of antihypertensive drugs...

Change in 6-minute walk distance (6MWD) has been used as a clinical marker in pulmonary hypertension. Determinants and worsening of 6MWD remain a matter of debate because nonpulmonary factors have an impact on the 6MWD. We hypothesized that future reduction of 6MWD in patients with systemic sclerosis (SSc) was more closely associated with cardiac dysfunction. We prospectively performed standard clinical and echocardiographic evaluations in SSc patients with the 6-minute walk test at enrollment. Features associated with the 6MWD were sought in a multiple linear regression analysis and compared using standardized β...

The prevalence of noncommunicable diseases, including chronic kidney disease (CKD), continues to increase worldwide, and mortality from noncommunicable diseases is projected to surpass communicable disease-related mortality in developing countries. Although the treatment of CKD is expensive, unaffordable, and unavailable in many developing countries, the current structure of the health care system in such countries is not set up to deliver comprehensive care for patients with chronic conditions, including CKD...

BACKGROUND: The Fontan circulation, a result of a palliative procedure in patients with single systemic ventricles, is defined by chronically elevated pulmonary vascular resistance. When traditional heart failure therapies fail, pharmacological agents that reduce pulmonary artery pressures may be used. These include endothelial-receptor antagonists, prostanoids and phosphodiesterase type 5 inhibitors. We report the first use of macitentan, an endothelin-receptor antagonist, in a patient with a Fontan circulation...

BACKGROUND: Dementia is a worldwide health concern, which leads to loss of autonomy. To date no curative treatment is available so focus on modifiable risk factors is of particular interest. Hypertension, particularly midlife high blood pressure, has been associated with an increased risk for cognitive decline and dementia including vascular dementia (Vad) and Alzheimer Disease (AD). In this context, antihypertensive treatments might have a preventive effect. OBJECTIVES: To examine the relationship between antihypertensive therapy and cognitive decline or dementia...

BACKGROUND/AIMS: A recent study revealed that global overexpression of ET-1 causes a slight reduction in systemic blood pressure. Moreover, heterozygous ET-1 knockout mice are hypertensive. The role of ET-1 in human hypertension was so far not addressed by a strict meta-analysis of published human clinical studies. METHODS: We included studies published between January 1, 1990 and February 28, 2017. We included case control studies analyzing untreated essential hypertension or hypertensive patients where antihypertensive medication was discontinued for at least two weeks...

BACKGROUND AND AIMS: Catheter-based renal denervation for the treatment of drug-resistant hypertension has been intensively investigated in recent years. To date, only limited data have been published using multi-electrode radiofrequency ablation systems that can deliver lesions with a pre-determined pattern. This study was designed to evaluate the safety and performance of the second generation EnligHTN™ Renal Denervation System. METHODS: This first-in-human, prospective, multi-center, non-randomized study included 39 patients (62% male, mean age 63 years, and mean baseline office blood pressure 174/93 mmHg) with drug-resistant hypertension...

BACKGROUND: Treatment modifications are necessary for addressing issues related to efficacy and tolerance of first-line monotherapy, but they increase the economic burden on patients and their health plans. Understanding the differences in costs between alternative treatment modification strategies, if any, can serve as a guideline for clinical decision making and for designing cost-containment strategies. OBJECTIVE: To compare the health care utilization costs between (a) addition (i...

Pulmonary arterial hypertension (PAH) has demonstrated multi-serotonin receptor dependent pathologies, characterized by increased tone (5-HT1B receptor) and complex lesions (SERT, 5-HT1B, 5-HT2B receptors) of the pulmonary vasculature together with right ventricular hypertrophy, ischemia and fibrosis (5-HT2B receptor). Selective inhibitors of individual signaling elements - SERT, 5-HT2A, 5HT2B, and combined 5-HT2A/B receptors, have all been tested clinically and failed. Thus, inhibition of tryptophan hydroxylase 1 (TPH1), the rate limiting step in 5-HT synthesis, has been suggested as a more broad, and thereby more effective, mode of 5-HT inhibition...

During hypoxia, the tissues do not obtain adequate oxygen. Chronic hypoxia can lead to many health problems. A relatively common cause of chronic hypoxia is sleep apnea. Sleep apnea is a sleep breathing disorder that affects 3 to 7% of the population. During sleep, the patient's breathing starts and stops. This can lead to hypertension, attention deficits, and hearing disorders. In this study, we apply an established chronic intermittent hypoxemia (CIH) model of sleep apnea to study its impact on auditory processing...

PURPOSE OF REVIEW: The central nervous system plays a pivotal role in the regulation of extracellular fluid volume and consequently arterial blood pressure. Key hypothalamic regions sense and integrate neurohumoral signals to subsequently alter intake (thirst and salt appetite) and output (renal excretion via neuroendocrine and autonomic function). Here, we review recent findings that provide new insight into such mechanisms that may represent new therapeutic targets. RECENT FINDINGS: Implementation of cutting edge neuroscience approaches such as opto- and chemogenetics highlight pivotal roles of circumventricular organs to impact body fluid homeostasis...

A 15-year-old girl presented with a unilateral sixth nerve palsy and papilledema following a severe headache. MR imaging showed thrombosis of the superior sagittal sinus and proximal right transverse sinus that were attributed to oral contraceptive use after a coagulation workup was negative. Systemic anticoagulation caused a hemorrhagic papillopathy in both eyes, raising the question as to whether anticoagulation should be discontinued. Diagnostic and management issues regarding cerebral venous sinus thrombosis with secondary intracranial hypertension are discussed...
