Small, dense low-density lipoproteins (LDL) are predictors of cardio- and cerebro-vascular events in subjects with the metabolic syndrome
2009
Summary Objective Small, dense low-density lipoproteins (LDL) are a feature of the metabolic syndrome (MS) but their predictive role still remains to be established. We performed a 2-year follow-up study in 124 subjects with MS (63 ± 6 years), as defined by the American Heart Association/National Heart, Lung and Blood Institute guidelines, to assess clinical and biochemical predictors of cerebro- and cardio-vascular events. Methods and results Beyond traditional cardiovascular risk factors, we measured LDL size and subclasses by gradient gel electrophoresis. Clinical events were registered in the 25% of subjects. At univariate analysis subjects with events had increased prevalence of elev…
Prevalence and impact of metabolic syndrome on hospital outcomes in acute myocardial infarction.
2005
The impact of metabolic syndrome after acute myocardial infarction (AMI) has not yet been studied. In a population-based sample of patients with AMI, we sought to determine the prevalence of metabolic syndrome in patients with AMI, its impact on hospital outcomes, and to assess the relative influence of each of the components of the National Cholesterol Education Program (NCEP) Adult Treatment Panel (ATP) III definition of metabolic syndrome on the risk of death and heart failure.A total of 633 unselected, consecutive patients hospitalized with AMI were categorized according to the NCEP ATP III metabolic syndrome criteria (presence of/=3 of the following: hyperglycemia; triglyceride level/=…
Early subclinical ventricular dysfunction in patients with insulin resistance
2014
AIMS: The aim of our study was to evaluate the relationship between insulin resistance and the detection of precocious echocardiographic signs of heart failure in patients with cardiovascular risk factors. METHODS: We enrolled 34 consecutive patients with cardiovascular risk factors. All patients underwent coronary angiography, echocardiography, and laboratory tests. Exclusion criteria were diabetes (fasting glucose greater than 126 mg/dl or treatment with insulin or oral hypoglycemic agents), coronary artery disease, creatinine above 1.5 mg/dl, left-ventricular hypertrophy, valvular heart disease, ejection fraction below 50%, atrial fibrillation, or other severe arrhythmia. The presence of…
Unrecognised cardiovascular disease in type 2 diabetes: is it time to act earlier?
2018
Abstract Cardiovascular disease (CVD) is the most significant prognostic factor in individuals with type 2 diabetes (T2D). However, a significant number of individuals may develop CVD that does not present with the classic angina-related or heart failure symptoms. In these cases, CVD may seem to be ‘silent’ or ‘asymptomatic’, but may be more accurately characterised as unrecognised diabetic cardiac impairment. An initial step to raise awareness of unrecognised CVD in individuals with T2D would be to reach a consensus regarding the terminology used to describe this phenomenon. By standardising the terminologies, and agreeing on the implementation of an efficient screening program, it is anti…
Flat Panel Computed Tomography Pooled Blood Volume and Infarct Prediction in Endovascular Stroke Treatment
2019
Background and Purpose— Patients with large-vessel stroke frequently need to be transferred to comprehensive stroke centers for endovascular treatment. An update of physiological perfusion parameters and stroke progression on arrival is desirable. We examined the reliability of preinterventional pooled blood volume (PBV)-maps acquired by flat-panel detector computed tomography (CT) in the interventional angiography suite. Methods— The volumes of preinterventional perfusion deficit in flat-panel detector CT-PBV source images were compared with final infarct volume on follow-up multislice-CT after endovascular treatment of 29 consecutive patients with occlusion of the middle cerebral artery …
A negative rapid urease test is unreliable for exclusion of Helicobacter pylori infection during acute phase of ulcer bleeding
2003
Abstract Background. The reliability of the rapid urease test has not been proven in patients with peptic ulcer bleeding. Some studies show bad diagnostic results with the rapid urease test for gastrointestinal bleeding. Aims. To evaluate the efficacy of the rapid urease test in patients with bleeding gastric or duodenal ulcers. Patients and methods. A total of 96 patients with acute peptic ulcer bleeding without proton pump inhibitor or antibiotic therapy within the last 14 days before bleeding were included into the study. During index endoscopy, specimens for histological and rapid urease test were obtained from the antrum and corpus mucosa of the stomach. Patients were also investigated…
Stool antigen assay (HpSA) is less reliable than urea breath test for post-treatment diagnosis of Helicobacter pylori infection
2002
Summary Background : The diagnostic yield of the stool antigen test (HpSA) in evaluating the results of Helicobacter pylori eradication therapy is controversial, but many studies have used only the 13C-urea breath test (13C-UBT) as a gold standard which has greatly reduced their relevance. Aim : To compare the reliability of HpSA and 13C-UBT in patients post-treatment using biopsy-based methods as reference tests. Methods : A total of 100 consecutive dyspeptic patients (42 male and 58 female; mean age, 56 ± 18 years) were enrolled in our study. All patients were H. pylori positive on the basis of at least two biopsy-based methods, and underwent 1 week of treatment with various triple therap…
Diagnostic Accuracy of <sup>13</sup>C-Urea Breath Test in the Diagnosis of <i>Helicobacter pylori</i> Infection in Patients w…
2001
<i>Aims:</i> We investigated the diagnostic properties of the <sup>13</sup>C-urea breath test (<sup>13</sup>C-UBT) prospectively. These are well validated in nonresected patients before and after treatment of <i>Helicobacter pylori</i> infection but not in patients with partial gastric resection due to peptic ulcer disease. <i>Methods:</i> Hospitalized patients with previous gastric resection and indications for upper gastrointestinal endoscopy were recruited for the study. Biopsy specimens were obtained from the fundus mucosa and the gastric remnant adjacent to the gastroenteric anastomosis for histological examination and rapid u…
Cancer screening and health system resilience: Keys to protecting and bolstering preventive services during a financial crisis
2012
The aim of this paper is to elucidate the rationale for sustaining and expanding cost-effective, population-based screening services for breast, cervical and colorectal cancers in the context of the current financial crisis. Our objective is not only to promote optimal delivery of high-quality secondary cancer prevention services, but also to underline the importance of strengthening comprehensive cancer control, and with it, health system response to the complex care challenges posed by all chronic diseases. We focus primarily on issues surrounding planning, organisation, implementation and resources, arguing that given the growing cancer burden, policymakers have ample justification for e…
Unusual Neuroendocrine Differentiation in a Small Round Cell Angiosarcoma: A Potential Histologic Mimicker of Superficial Ewing Sarcoma.
2018
Neuroendocrine differentiation or aberrant expression of neuroendocrine markers is very uncommon in angiosarcomas (AS) and creates a challenging differential diagnosis with other superficial or soft tissue tumors. Herein, we report a new case of superficial AS presenting as a tumor lesion on the little finger of the right hand of a 52-year-old man. The tumor displayed CD56, chromogranin-A, and synaptophysin immunoreactivity. Tumor cells were positive for vascular markers (CD31, FLI1, ERG, D2-40, VE-cadherin, VEGR1,2, and 3), CD99, and EMA, but were negative for S100, CK (AE1/AE3), CK20, polyomavirus, and myogenic (desmin and myogenin) and melanocyte markers (melan-A and HMB45).
