Yan Xu, Yanpeng Cai, Tao Sun, Qian Tan
In this paper, an improved multi-scale integrated modeling framework has been established to evaluate coastal reclamation intensity (CRI). About 7 indicators are considered, including ecological degradation intensity (EDI), hydrodynamic disturbance (IHD), engineering types, water quality, economic investment, population growth, and reclaimed land area. Meanwhile, an integrated framework enhanced methods in terms of (a) measuring intensity of ecological degradation process under multi-scale impact, (b) developing the indicator system of CRI, and discussing the driving forces and trends of coastal reclamation, (c) determining fuzzy preference relations of weight and calculating the specific value of CRI with the case study areas of Yellow River estuary from 2000 to 2015...

Caroli disease (CD) is a rare congenital malformation of the liver characterized by non-obstructive, segmental, cystic dilatation of the intrahepatic bile ducts (IHDs). The clinical course is usually asymptomatic for the first 5-20 years, and symptoms may seldom occur throughout the patient's life. Bile stagnation leads to recurrent episodes of cholangitis, stone formation, or liver abscesses, and biliary cirrhosis usually occurs years later. Here we report on a 42-year-old man diagnosed with diffuse-type CD with a characteristic central dot sign, who had multiple intrahepatic and common bile duct (CBD) stones...

OBJECTIVE: Although contemporary mortality data are important for health assessment and planning purposes, their availability lag several years. Statistical projection techniques can be employed to obtain current estimates. This study aimed to assess annual trends of mortality in Puerto Rico due to cancer and Ischemic Heart Disease (IHD), and to predict shorterm and longterm cancer and IHD mortality figures. METHODS: Age-adjusted mortality per 100,000 population projections with a 50% interval probability were calculated utilizing a Bayesian statistical approach of Age-Period-Cohort dynamic model...

BACKGROUND: Obese insulin-resistance is one of the most important risk factor for cardiovascular diseases including ischemic heart disease (IHD). Growing evidences suggest that the susceptibility to myocardial ischemia-reperfusion (I/R) injury is increased in an obese insulin-resistance condition. Based on the currently available evidence from human and animal studies, this review mainly focuses on the influence of obese insulin-resistance on the outcome of the I/R insult to the heart...

BACKGROUND: The pathogenic role of ischemic heart disease (IHD) in heart failure (HF) with reduced ejection fraction (HFrEF; EF <40%) is well established, but its pathogenic and prognostic significance in HF with midrange (HFmrEF; EF 40%-50%) and preserved EF (HFpEF; EF ≥50%) has been much less explored. METHODS AND RESULTS: We evaluated 42 987 patients from the Swedish Heart Failure Registry with respect to baseline IHD, outcomes (IHD, HF, cardiovascular events, and all-cause death), and EF change during a median follow-up of 2...

James Thomas Connell
Saphenovenous graft aneurysm is a rare complication of coronary artery bypass grafts that is likely underdiagnosed. It is typically asymptomatic, slow growing, and often diagnosed incidentally on angiography or following catastrophic rupture. There is no consensus on best management but PCI and surgery appear to have more favourable mortality outcomes relative to conservative management. We present the case of a 48-year-old male with a cardiovascular risk profile hallmarked by diabetes mellitus, end stage renal failure, recalcitrant hyperlipidaemia, and IHD previously treated with CABG...

BACKGROUND: The American College of Cardiology (ACC) Appropriate Use Criteria (AUC) for radionuclide myocardial perfusion scans (MPS) was developed to promote its rational use in the assessment of stable ischaemic heart disease (IHD). We sought to validate the applicability of this document in the Australian context. METHODS: 1009 consecutive patients who underwent MPS were retrospectively audited at a single major metropolitan hospital in Victoria, Australia. Appropriateness was assigned based on the 2013 ACC AUC, and common indications and predictors of positive scan results were examined...

The single-frequency precise point positioning (PPP) technique has attracted increasing attention due to its high accuracy and low cost. However, a very long convergence time, normally a few hours, is required in order to achieve a positioning accuracy level of a few centimeters. In this study, an approach is proposed to accelerate the single-frequency PPP convergence by combining quad-constellation global navigation satellite system (GNSS) and global ionospheric map (GIM) data. In this proposed approach, the GPS, GLONASS, BeiDou, and Galileo observations are directly used in an uncombined observation model and as a result the ionospheric and hardware delay (IHD) can be estimated together as a single unknown parameter...

Ischemic heart disease (IHD) remains the single most common cause of death worldwide. Ischemic cardiomyopathy is a major sequel of coronary artery disease. The economic health burden of IHD is substantial. In patients with old myocardial infarction (OMI), the extent of viable myocardium (VM) directly affects the short- and long-term outcome. There is a considerable collection of observational data showing substantial improvement in patients with significant left ventricular dysfunction when the need for revascularization is guided by preoperative assessment of viability and hibernation...

Childhood obesity predicts the risk of adult adiposity, which is associated with the earlier onset of cardiovascular disease [adult atherosclerotic cardiovascular disease, ACVD: hypertension, increased carotid intima media thickness (CIMT) stroke, ischemic heart disease (IHD)] and dysglycaemia. Because it is not known whether childhood obesity contributes to these diseases, we conducted a systematic review of studies that examine the ability of measures of obesity in childhood to predict dysglycaemia and ACVD...

REVIEW
Roxana Campisi, Fernando D Marengo
Traditional approaches for risk assessment of ischemic heart disease (IHD) are based on the physiological consequences of an epicardial coronary stenosis. Of note, normal coronary arteries or nonobstructive coronary artery disease (CAD) is a common finding in women with signs and symptoms of ischemia. Therefore, assessment of risk based on a coronary stenosis approach may fail in women. Positron emission tomography (PET) quantifies absolute myocardial blood flow (MBF) which may help to elucidate other mechanisms involved such as endothelial dysfunction and alterations in the smooth muscle cell relaxation responsible for IHD in women...

INTRODUCTION: There are no obvious guidelines for therapy of elevated blood pressure (BP) in the emergency department (ED). Diastolic BP is probably more difficult to control compared with systolic BP. AIM: To characterize patients who respond with a significant decrease in diastolic BP in the ED, whether treated or not. METHODS: In this retrospective cohort study, all patients attending a tertiary care ED with elevated BP were evaluated. Clinical characteristics of patients in whom diastolic BP decreased ≥20% were compared with those in whom diastolic BP decreased <20%...

BACKGROUND: Arterial hypertension is the commonest cause of cardiovascular death. It may lead to hypertensive heart disease (HHD), including heart failure (HF), ischemic heart disease (IHD) and left ventricular hypertrophy (LVH). MAIN BODY: According to the 2007 ESH/ESC guidelines, the recommended imaging technique is echocardiography (echo), when a more sensitive detection of LVH than that provided by ECG, is needed. Cardiovascular Magnetic Resonance (CMR), a non-invasive, non-radiating technique, offers the following advantages, beyond echo: a) more reliable and reproducible measurements of cardiac parameters such as volumes, ejection fraction and cardiac mass b) more accurate differentiation of LVH etiology by providing information about tissue characterisation c) more accurate evaluation of myocardial ischemia, specifically if small vessels disease is present d) technique of choice for diagnosis of renovascular, aortic tree/branches lesions and quantification of aortic valve regurgitation e) technique of choice for treatment evaluation in clinical trials...

The aim is to investigate if the effect of a health check differs between areas with different participation rates. The Inter99 population-based randomized lifestyle intervention study covered 73 areas within the suburbs of Copenhagen, Denmark. Adults aged 30-60years were randomly drawn from a population and were randomized to intervention group (n=11,483) or control group (n=47,122). Participation rates in the health check varied considerably between areas (mean 52%; range 35-85%). In separate survival analyses, area participation rate was included both as a continuous exposure variable and as a categorical variable (tertiles; low: 35-49%, meddle: 50-54%, high: 55-84%)...
