EFFICACY OF A LIPID-LOWERING DIET ON KEY FATTY ACID RATIOS AND OMEGA-3 INDEX IN HYPERLIPIDEMIC SUBJECTS.

Polyunsaturated fatty acid (PUFA) dietary intake, status and serum key fatty acid (FA) ratios may aid in cardiovascular disease-related risk assessment. The aim of this study was to investigate the effects of lipid-lowering diet on key FA ratios in serum phospholipids and omega-3 index in erythrocyte phospholipids in moderately hyperlipidemic subjects. The study included 41 subjects, mean age 56±6 years.

Work motivation and job satisfaction of health workers in urban and rural areas.

Background/aim: Motivated and job satisfied health professionals represent a basis of success of modern health institutions. The aim of this study was to investigate whether there was a difference in work motivation and job satisfaction between health workers in urban and rural areas in the region of Central Serbia.

Methods: The study included 396 health professionals from urban setting, and 436 from a rural area, employed in four randomly selected health facilities.

[The relationship between C-reactive protein and subclinical carotid arteriosclerosis in military pilots].

Background/aim: Inflammation plays a key role in the physiopathology of arteriosclerosis. C-reactive protein (CRP) and common carotid artery intima-media thickness are independent predictors of cardiovascular events and diabetes mellitus in apparently healthy men, but relationship between them is not fully elucidated. The aim of the study was to assess the cross-sectional relationship between CRP and cardiovascular risk factors with common carotid artery intima-media thickness in military pilots as representatives of healthy men.

[Effect of acclimation on changes in water and electrolyte homeostasis in soldiers during exertional heat stress].

Background/aim: Exertional heat stress is a common problem in military services. The aim of this study was to exemine changes in body water and serum concentrations of some electrolites in soldiers during exertional heat stress (EHST), as well as effects of 10-day passive or active acclimation in a climatic chamber.

Methods: Forty male soldiers with high aerobic capacity, performed EHST either in cool (20 degrees C, 16 degrees C WBGT-wet bulb globe temperature), or hot (40 degrees C, 25 degrees C WBGT) environment, unacclimatized, or after 10 days of passive or active acclimation.

[Influence of orlistat therapy on serum insulin level and morphological and functional parameters of peripheral arterial circulation in obese patients].

Background/aim: Insulin resistance is related to accelerated atherosclerosis, whereas weight loss is associated with the increasing insulin sensitivity, the improvement of functional and the morphological parameters of arterial circulation, and the reduction of cardiovascular morbidity and mortality. The aim of our study was to evaluate the influence of orlistat treatment on serum insulin level and functional and morphologic parameters of peripheral arterial circulation.

Methods: We conducted a prospective, randomized, double - blind, placebo - controlled study.

[Cigarette smoking in military pilots and intima-media thickness of the carotid arteries].

Background: It is well known that smoking is associated with an increase in arterial wall thickness. However, most studies of this problem have been undertaken in age and sex heterogenous groups, as well as in patients with already present other conventional risk factors. The aim of this study was to assess the effect of cigarette smoking on arterial wall thickness of the common carotid artery in asymptomatic pilots.
