AIMS To investigate if diet quality is related to incidence of cardiovascular (CV) events. SUBJECTS AND METHODS A diet quality index based on the 2005 Swedish Nutrition Recommendations and the Swedish Dietary Guidelines was created and included six dietary components: saturated fatty acids, polyunsaturated fatty acids, fish and shellfish, dietary fiber, fruit and vegetables, and sucrose. The ...

A study on natural radioactivity in virgin and agricultural soil samples collected from Sungai Petani was conducted using high-purity germanium. The mean activity concentrations of 226Ra, 232Th, and 40K in virgin soils were 51.06±5.83, 78.44±6.42, and 125.66±7.26 Bq kg−1, respectively, while those in agricultural soils were 80.63±5.78, 116.87±7.87, and 200.66±18.24 Bq kg−1, respectively. The co...

BACKGROUND AND PURPOSE The American Heart Association developed the ideal cardiovascular health (CVH) index as a simple tool to promote CVH; yet, its association with brain atrophy and dementia remains unexamined. METHODS Our aim was to investigate the prospective association of ideal CVH with vascular brain injury, including the 10-year risks of incident stroke and dementia, as well as cogni...

Survival analysis focuses on modeling and predicting the time to an event of interest. Many statistical models have been proposed for survival analysis. They often impose strong assumptions on hazard functions, which describe how the risk of an event changes over time depending on covariates associated with each individual. In particular, the prevalent proportional hazards model assumes that co...

Objective The purpose of this study was to present the recent clinical profiles and the real-world management of infective endocarditis (IE). Methods All medical records of patients with IE were reviewed retrospectively for their clinical data, including clinical presentation, laboratory results, blood cultures, echocardiographic findings, treatments and complications. Using the clinical data c...

Introduction: One of the sources of natural occurring radiation was soils. The purpose of article was to determine soil pollution by radiation absorbed dose rate, radium equivalent activity, external hazard index, annual gonad dose equivalent and annual effective dose equivalent. Methods & Materials: The soil samples was located in Chahbahar city in Blouchestan of Iran, was chosen for studyin...

BACKGROUND Functional dependency, the need for help in basic activities of daily living, is an important patient-oriented outcome. We aimed to describe the development of dependency in Parkinson's disease (PD) and identify independent prognostic factors for this outcome. METHODS We analyzed data from the Parkinsonism Incidence in North-East Scotland (PINE) study, a prospective, community-base...

This thesis centers on nonparametric inferences of the cumulative hazard function of a right truncated variable. We present three variance estimators for the Nelson-Aalen estimator of the cumulative hazard function and conduct a simulation study to investigate their performances. A close match between the sampling standard deviation and the estimated standard error is observed when an estimated...

Background: The concentrations of heavy metals in the tissues and organs of fishes indicate the concentrations of heavy metals in water and their accumulation in food chains. In the present study, the concentrations of Zn, Cu, Cd, Ni, V and Pb in three common species of fish and the potential health risks to local residents via consumption of the fishes were estimated.  Methods: The con...
