Cardiovascular complications induced by high fat are one of the most challenging health problems presently. Oxidative stress, inflammation and fibrosis are major components included in the pathology of diabetic cardiomyopathy. Nuclear factor erythroid 2-related factor 2 (Nrf2) has been reported as an essential therapeutic target in various diseases for its induction of anti-oxidant enzymes, and other protective enzymes. Additionally, a number of Nrf2 activators showed strong anti-inflammatory properties. In the study, we calculated the Nrf2-dependent anti-oxidant, anti-inflammatory and anti-fibrosis effects of chrysophanol in high fat diet-induced diabetic heart injury...

Human-activity recognition (HAR) and energy-expenditure (EE) estimation are major functions in the mobile healthcare system. Both functions have been investigated for a long time; however, several challenges remain unsolved, such as the confusion between activities and the recognition of energy-consuming activities involving little or no movement. To solve these problems, we propose a novel approach using an accelerometer and electrocardiogram (ECG). First, we collected a database of six activities (sitting, standing, walking, ascending, resting and running) of 13 voluntary participants...

BACKGROUND: The cardiorenal syndrome (CRS) is a major health problem in our aging population. The term was introduced to cover disorders of the kidneys and heart, whereby dysfunction of one organ may induce dysfunction of the other. As the natural history of the CRS is mostly slow, hence difficult to explore in clinical trials, adequate animal models combining cardiovascular and renal disease are required. Therefore, we developed and characterized a usable model for CRS type 4, i.e. chronic kidney disease (CKD) causing cardiac dysfunction...

Viral infections of the heart cause serious clinical problems, either as infectious myocarditis, which usually is a consequence of acute infection or as idiopathic dilated cardiomyopathy, resulting rather from a chronic infection. This minireview presents an up-to-date view on pathomechanisms of viral infection of the heart tissues, the role of immune system in controlling infectious process at its various stages and current possibilities of recognizing viral infection of the heart with use of both cardiological and virological methods...

BACKGROUND AND OBJECTIVE: Histological images have characteristics, such as texture, shape, colour and spatial structure, that permit the differentiation of each fundamental tissue and organ. Texture is one of the most discriminative features. The automatic classification of tissues and organs based on histology images is an open problem, due to the lack of automatic solutions when treating tissues without pathologies. METHOD: In this paper, we demonstrate that it is possible to automatically classify cardiovascular tissues using texture information and Support Vector Machines (SVM)...

OBJECTIVES: Communication and planning for heart failure (HF) care near the end of life is known to be complex. Little is known about how the patient experience of palliative assessment and communication needs change over time, and how this might inform management. Our aim was to explore experiences of giving or receiving a prognosis and advanced palliative care planning (ACP) for those with HF. METHODS: We carried out a longitudinal grounded theory study, employing in-depth interviews with 14 clinicians (primary and secondary care) and observations of clinic and home appointments, followed by a series of interviews with 13 patients with HF and 9 carers...

OBJECTIVE: Studies have shown that famine exposure during early life may increase the risk of cardiovascular disease (CVD), hypertension, and diabetes during adulthood. We aimed to assess whether exposure to the Chinese famine (1959-1961) modifies the association between hypertension and CVD. METHODS: We investigated data of 5772 adults born between 1954 and 1964 from the China Health and Retirement Longitudinal Study. CVD was based on self-reported doctor's diagnosis of heart problems (heart attack, coronary heart disease, angina, congestive heart failure, or other heart problems) and stroke...

INTRODUCTION: In times of organ shortage, death while on the heart waiting-list still represents a major problem. As a consequence, bridging to transplant as well as the decision when to escalate therapy play a very important role. METHODS AND RESULTS: We report on two young patients with dilated cardiomyopathy and acute decompensation who were successfully bridged to heart transplantation with both left and temporary right ventricular assist devices in just 2 months...

This study aims to evaluate the rate, predictors, and causes of 30-day readmissions in a single tertiary hospital in the United Kingdom. We conducted a retrospective study of all patients admitted between 2012 and 2014 with a diagnosis of acute myocardial infarction, who were in the Myocardial Infarction National Audit Project register. Data on patient demographics, comorbidities, care received, and in-hospital mortality were collected. Rates of 30-day readmission and causes of readmission were evaluated. Univariate and multiple logistic regressions were used to identify predictors of all-cause, cardiac, and noncardiac readmission...

Thomas A Schwann
Coronary artery disease remains a formidable challenge to clinicians. Percutaneous interventions and surgical techniques for myocardial revascularization continue to improve. Concurrently, in light of emerging data, multiple practice guidelines have been published guiding clinicians in their therapeutic decisions. The multidisciplinary Heart Team concept needs to be embraced by all cardiovascular providers to optimize patient outcomes.

Metabolic disease is a significant problem that causes a range of species-specific comorbidities. Recently, a better understanding of glucose-dependent insulinotropic polypeptide (GIP) biology has led to the suggestion that inhibiting its action may attenuate obesity in several species. In horses, antagonism of GIP may also reduce hyperinsulinemia, which leads to insulin-associated laminitis, a painful comorbidity unique to this species. However, little is known about GIP in horses. The aims of this study were to examine the tissue distribution of equine GIP receptors (eGIPR), to determine whether eGIPR can be blocked using a GIP antagonist not tested previously in horses, and to establish whether there is any association between GIP concentrations and body mass in this species...

INTRODUCTION: Emotion dysregulation (ED) has long been recognized in clinical descriptions of attention-deficit hyperactivity disorder (ADHD), but a renewed interest in ED has advanced research on the overlap between the two entities. Autonomic reactivity (AR) is a neurobiological correlate of emotion regulation; however, the association between ADHD and AR remains unclear. Our aim was to explore the clinical differences, AR, and subjective emotional responses to visual emotional stimuli in ADHD children with and without ED...

Coronary heart disease preoperative diagnosis plays an important role in the treatment of vascular interventional surgery. Actually, most doctors are used to diagnosing the position of the vascular stenosis and then empirically estimating vascular stenosis by selective coronary angiography images instead of using mouse, keyboard and computer during preoperative diagnosis. The invasive diagnostic modality is short of intuitive and natural interaction and the results are not accurate enough. Aiming at above problems, the coronary heart disease preoperative gesture interactive diagnostic system based on Augmented Reality is proposed...

BACKGROUND: The potential harm from exposure to nonessential metals, particularly mercury (Hg) and lead (Pb), has been the focus of research for years. Initial interest focused on relatively high exposures; however, recent evidence suggests that even background exposures might have adverse consequences for child development. Identifying the extent of these consequences is now a priority. METHODS: We assessed blood Pb and Hg levels in a biracial sample of 9-11 year-old children (N = 203)...

INTRODUCTION: Several studies report a decrease of fetal heart rate (FHR) short-term variation (STV) after corticosteroids for improvement of fetal maturity and advice not to deliver a fetus for low STV within 2-3days after corticosteroids. However, literature is not unanimous in this respect. This study intends to asses STV longitudinally after corticosteroid administration. MATERIAL AND METHODS: A retrospective cohort study in a tertiary perinatal centre from 2009 to 2015 included all women who had been treated with corticosteroids at gestational age of 26-34 weeks, had a computerized cardiotocography (cCTG) before and after medication and did not deliver within 48h...

Previous research has revealed a consistent association between heart rate at rest and during stress and behavioral problems, potentially implicating autonomic nervous system (ANS) functioning in the etiological development of antisocial behavior. A complementary line of research has focused on the potential independent and interactive role of the two subsystems that comprise the ANS, the parasympathetic nervous system (PNS) and the sympathetic nervous system (SNS), on behavioral problems. The current study aims to contribute to the existing literature by examining the influence of heart rate (HR) reactivity, high-frequency heart rate variability (HF-HRV) reactivity, and catecholamine activity on a comprehensive measure of anger in a large, nationally-representative sample of adults from the United States...
