The predictive value of blood pressure (BP) for cardiovascular morbidity and mortality diminishes in the elderly, which may be confounded and compensated by the BP differences across the 4 limbs, markers of peripheral arterial disease. In a prospective elderly (≥60 years) Chinese study, we performed simultaneous 4-limb BP measurement using an oscillometric device in the supine position, and cal...

BACKGROUND This study was conducted to assess the validity and reliability of ankle-brachial index (ABI) by oscillometric blood pressure (BP) measurement as compared with an automated ABI as a gold standard. MATERIALS AND METHODS This study was conducted at Golden Jubilee Medical Center, Thailand. All the data were collected from 303 patients at risk of peripheral arterial disease (PAD) who w...

Cardiovascular disease remains a major cause of morbidity and mortality in the United States. Peripheral artery disease (PAD) is a manifestation of systemic atherosclerosis that confers a significantly increased risk of myocardial infarction, stroke, and death. Whether cardiovascular risk can be reduced by implementation of secondary prevention therapies (such as antiplatelet therapy, statins, ...

Purpose: To determine the usefulness of pulse oximetry in patients receiving iloprost infusion for treatment of critical limb ischemia unsuitable for revascularization. Material and methods: A total of 42 patients [28 male, mean age 61.80±5.81 years] were included. Patients were those who considered as unsuitable for revascularization based on angiographic study and received single-dose infusio...

BACKGROUND Peripheral arterial disease is a common condition in the hemodialysis population with an estimated prevalence ranging from 17-48%. Many studies have been conducted to know the prevalence of peripheral vascular disease in hemodialysis population. However no such study has been conducted so far in Nepal. OBJECTIVE This study was carried out with an objective to assess the prevalence ...

The southern oscillation index (SOI) is a characteristic of the El Niño phenomenon. SOI monthly averaged data is analyzed for the time interval 1866-2000. The tail of the cumulative distribution of the fluctuations of SOI signal is studied in order to characterize the amplitude scaling of the fluctuations and the occurrence of extreme events. Large fluctuations are more likely to occur than the...

In literature, we can find different metrics to evaluate the detected edges in digital images, like Pratt's figure of merit (FOM), Jaccard's index (JI) and Dice's coefficient (DC). These metrics compare two images, the first one is the reference edges image, and the second one is the detected edges image. It is important to mention that all existing metrics must binarize images before their eva...

Background Questionnaires are essential for measurement of tinnitus severity and treatment-related change. Yet no standard measure is used across clinical and research settings. Current tinnitus questionnaires are limited to measuring severity or change, but not both [1,2]. The Tinnitus Functional Index (TFI) was developed as both a diagnostic measure of the functional impact of tinnitus and to...
