BACKGROUND: Rheumatoid arthritis (RA) is a chronic inflammatory condition characterised by reduced heart rate variability (HRV) of unknown cause. We tested the hypothesis that low HRV, indicative of cardiac autonomic cardiovascular dysfunction, was associated with systemic inflammation and pain. Given the high prevalence of hypertension (HTN) in RA, a condition itself associated with low HRV, we also assessed whether the presence of hypertension further reduced HRV in RA. METHODS: In RA-normotensive (n=13), RA-HTN (n=17), normotensive controls (NC; n=17) and HTN (n=16) controls, blood pressure and heart rate were recorded...

The purpose of the present study was to investigate the effect of salidroside (Sal) on myocardial injury in lipopolysaccharide (LPS)-induced endotoxemic in vitro and in vivo. SD rats were randomly divided into five groups: control group, LPS group (15 mg/kg), LPS plus dexamethasone (2 mg/kg), LPS plus Sal groups with different Sal doses (20, 40 mg/kg). Hemodynamic measurement and haematoxylin and eosin staining were performed. Serum levels of creatine kinase (CK), lactate dehydrogenase, the activities of the antioxidant enzymes catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GSH-px), glutathione, tumour necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β) were measured after the rats were killed...

BACKGROUND: Advances in radiotherapy (RT) have allowed an increased proportion of lung cancer patients to be treated curatively. High doses delivered to critical thoracic organs can result in excess mortality with tolerance doses poorly defined. This work presents a novel method of identifying anatomical dose-sensitive regions within the thorax. METHODS: A high-resolution, normal-tissue dosimetric analysis was performed to identify regions in the heart that correlate with poorer survival...

Breast carcinoma is the most common invasive cancer in women worldwide. It metastasizes commonly to bone, lungs, regional lymph nodes and brain. Cardiac metastasis of lung and breast cancers is a known but rare complication of advanced disease with tumour metastasising to pericardium via the locoregional lymphatic system. Here we present a case of 59-year-old female presenting with right upper limb oedema, facial puffiness and features of Superior Vena Cava (SVC) syndrome 15 years after mastectomy and adjuvant chemotherapy, radiotherapy for carcinoma of the right breast...

Liposarcoma is regarded as the second most common soft tissue malignant tumour. Metastasis of liposarcoma to the heart is very rare, and to date, less than 40 cases have been reported in the literature. We report a 46 year-old male with myxoid liposarcoma of the lower extremity who developed extensive metastasis to the left ventricle, pulmonary artery, and pericardium. The patient presented with acute symptoms of dyspnea 16 years after surgical resection of the primary tumour, and his dyspnea progressed to cardio-respiratory arrest within the first few days of hospital admission...

The carcinoid syndrome is rare but it is associated with carcinoid heart disease in more than a half of the cases. Carcinoid heart disease is typically characterised by morphological and functional modifications of right-sided valves. Its aetiology is probable multifactorial but serotonin appears to play a key role in the development of this valvular disease. Unlike gastrointestinal neuroendocrine tumours, ovarian neuroendocrine tumours can present with carcinoid syndrome and carcinoid heart disease in the absence of liver metastases; such ovarian neuroendocrine tumours are a unique clinical entity...

Heart valve diseases (HVDs) arise from a number of different processes that affect both the structure and function of the valve apparatus. Despite diverse aetiologies, treatments for HVDs are limited to percutaneous or surgical interventions. The search for medical therapies to prevent or slow the progression of HVDs has been hampered by our poor understanding of the progression from subclinical to symptomatic phases, and our limited knowledge of the molecular signals that control the susceptibility of valve interstitial cells to pathological remodeling...

Meditation is a popular form of stress management, argued to mediate stress reactivity. However, many studies in this field commonly fail to include an active control group. Given the frequency with which people are selecting meditation as a form of self-management, it is important to validate if the practice is effective in mediating stress-reactivity using well-controlled studies. Thus, we aimed to conduct a meta-analysis investigating the neurobiological effects of meditation, including focused attention, open monitoring and automatic self-transcending subtypes, compared to an active control, on markers of stress...

BACKGROUND: Phase II trials suggested that survival rates for locally advanced lung cancer could be increased by radiotherapy dose escalation. However, results of the phase III RTOG 0617 trial illustrated an imminent risk of treatment-related death. This could be thwarted with strict constraints to organs at risk (OARs) and control of the delivered dose. This study investigates the impact of anatomical changes during radiotherapy on escalated dose distributions used in the Danish NARLAL2 dose escalation trial...

REVIEW
Nicholas D Hastie
The study of genes mutated in human disease often leads to new insights into biology as well as disease mechanisms. One such gene is Wilms' tumour 1 (WT1), which plays multiple roles in development, tissue homeostasis and disease. In this Primer, I summarise how this multifaceted gene functions in various mammalian tissues and organs, including the kidney, gonads, heart and nervous system. This is followed by a discussion of our current understanding of the molecular mechanisms by which WT1 and its two major isoforms regulate these processes at the transcriptional and post-transcriptional levels...

BACKGROUND/AIMS: C1q and tumour necrosis factor-related protein 1 (CTRP1) possesses anti-atherogenic and anti-inflammatory effects. This study investigated whether the CTRP1 levels in the plasma and epicardial adipose tissue (EAT) were associated with congestive heart failure (CHF) and to disclose possible molecular mechanisms. METHODS: Plasma and tissue samples were obtained from subjects with or without CHF. Plasma levels of CTRP1 were measured by ELISA. The mRNA levels of CTRP1 and inflammatory cytokines were detected by RT-PCR...

Blood cysts are benign, congenital tumours of the heart endothelium, found most commonly on heart valves. Adult cases are rare, since most spontaneously regress with age. However, reports of symptomatic cases with embolic phenomena and valve dysfunction have been described. We present a case of a previously healthy 44-year-old woman with no cardiovascular risk factors who developed acute myocardial infarction caused by coronary artery embolism from a blood cyst of the anterior mitral valve leaflet.

BACKGROUND AND AIMS: Paediatric cardiac surgery with cardiopulmonary bypass (CPB) is associated with a marked inflammatory response and triggers release of inflammatory cytokines. The aim of this study was to study the effect of ketamine on the inflammatory response during correction of congenital cyanotic heart diseases. METHODS: Sixty-six patients with congenital cyanotic heart diseases scheduled for cardiac surgery were randomised into three groups. Group A patients did not receive ketamine (control group), Group B patients received 2 mg/kg ketamine intravenous (IV) and Group C patients received ketamine 2 mg/kg IV and an IV infusion of ketamine (50 μg/kg/min)...

Vasovagal tonus index (VVTI) is an indirect measure of heart rate variability and may serve as a marker of disease severity. Higher heart rate variability has predicted lower tumour burden and improved survival in humans with various tumour types. The purpose of this pilot study was to evaluate VVTI as a biomarker of remission status in canine lymphoma. The primary hypothesis was that VVTI would be increased in dogs in remission compared to dogs out of remission. Twenty-seven dogs were prospectively enrolled if they had a diagnosis of intermediate to high-grade lymphoma and underwent multidrug chemotherapy...

Caffeic acid phenethyl ester (CAPE), extracted from propolis, was proven to inhibit colon cancer. Caffeic acid p-nitro-phenethyl ester (CAPE-pNO2), a derivative of CAPE, was determined to be an anti-platelet agent and a protector of myocardial ischaemia with more potent effects. In the present study, CAPE-pNO2 showed stronger cytotoxic activity than CAPE. We revealed interactions between CAPE-pNO2 and experimental cells. CAPE-pNO2 induced apoptosis in HT-29 cells by up-regulating P53, cleaved-caspase-3, Bax, P38 and CytoC; CAPE-pNO2 also up-regulated P21(Cip1) and P27(Kip1) and down-regulated CDK2 and c-Myc to promote cell cycle arrest in G0/G1...

Malignant fibrous histiocytoma (MFH) represents a rare malignant affection of heart and aorta. Its clinical presentation depends on the localisation, size, degree of invasion and metastasis. Previously, relatively few cases of acute tumour mass embolisation into the visceral and limb arterial system were described in the literature. In the present case study we describe a case of acute ischemia of both lower extremities caused by thromboembolic mass of MFH cells. According to literary sources this tumour type is characterized by poor prognosis as it was in the case of our patient...
