Abstract	Background While obesity is recognisably associated with changes in heart rate variability (HRV), the association between skeletal muscle mass and HRV is less clear. Aims In this cross sectional study, we analysed the association of body fat (four parameters) and muscle mass (five parameters) with indicators of HRV activity. Subjects and methods Assessment of body composition and HRV was performed in n = 180 young-to-middle age healthy men exposed to high occupational physical activity, using the multi-frequency bioelectrical impedance device and the PPG-StressFlow® HRV photoplethysmography device, respectively. Results Mean values of parameters of fat tissue were above normal/reference values. Muscle tissue indicators were higher or within the reference ranges. Fat tissue parameters were significantly higher in participants with lower parasympathetic nervous system (PNS) indicators. Weight-adjusted skeletal muscle index (wSMI) was significantly lower in men with reduced PNS parameters. Fat tissue parameters were negatively correlated with PNS parameters, while wSMI was positively correlated with PNS parameters. Conclusions Participants with higher fat mass and lower muscle mass had poorer parasympathetic activity. Since mean values of HRV parameters indicated mild parasympathetic dominance, we conclude that physical activity and consequently good muscle mass potentially compensated for the negative interaction between fat tissue and HRV.

Abstract	Aim: Hemodialysis patients present with signs of chronic systemic inflammation. Periodontitis can also trigger systemic inflammation and thus affect sarcopenia. The aim of the study was to examine the presence of sarcopenia and periodontitis in patients on chronic hemodialysis and see whether there is a correlation between them. Methods: The study included 53 patients on hemodialysis. Oral status and routine laboratory parameters, as well as body composition and handgrip strength, were measured. Results: 20.8% of patients had sarcopenia, while 69% had stage 4. periodontitis. No statistically significant correlation was found between sarcopenia and periodontitis, but fat mass (FM%) correlated positively with tooth loss (rho = 0.313, p = 0.027), as well as muscle fat (IMAT) (rho = 0.393, p = 0.005). Percentage of skeletal muscle in relation to body weight (wSMI) correlated negatively with tooth loss (rho = -0.393, p = 0.005), as well as the grip strength of the dominant hand (rho = -0.294, p = 0.043). Conclusion: In this pilot study, the correlation between sarcopenia and periodontitis in patients on HD ‘was not determined, but a significant correlation of body composition parameters with tooth loss was found, which should be tested in a larger cohort of patients.

Abstract	Objectives: Osteoprotegerin (OPG) has an important role in bone remodeling, and it has been proposed that the OPG gene might be a candidate gene for osteoporosis predisposition. Several studies have already assessed the connection between OPG gene polymorphism and bone mineral density (BMD). In this study we wanted to analyze the association of two polymorphisms in the OPG gene with BMD and bone turnover markers in women with and without osteoporosis. Material and methods: In 22 postmenopausal women with osteoporosis (aged 65.6 ±12.6) and 59 women without osteoporosis (aged 60.8 ±8.7) we analyzed the association of two polymorphisms in the OPG gene with BMD, measured by dual energy absorptiometry and with bone turnover markers (crosslaps and osteoprotegerin). A163G, G209A, T245G and G1181C polymorphisms were determined. Results: No significant differences in age, anthropometry, number of fractures, osteocalcin and cross-laps were found between women with and without osteoporosis. Women with osteoporosis were significantly longer in postmenopause. Significantly more women with osteoporosis had AG polymorphism (p = 0.038) compared to women without osteoporosis, while no significant difference was found in prevalence of TT and GG polymorphism between patients with and without osteoporosis. No relationship was found between investigated polymorphism and bone turnover markers. A significant negative correlation between total hip BMD and crosslaps (p = 0.046) as well as between total hip T score and crosslaps (p = 0.044) was found in women without osteoporosis Conclusions : Postmenopausal women with osteoporosis had AG polymorphism more frequently than women without osteoporosis. Our results indicate that A163G polymorphism could have an impact on higher bone loss in postmenopausal women.

Abstract	The aim of this study was to determine the portion of the milk and dairy products as source of energy, macronutrients and calcium in average daily diet of adolescents according to sex and living area. A group of four hundred and forty one adolescents (46 % from rural, and 54 % from urban area in Croatia), both sexes, between 15 to 18 years of age, who attended high school represented the study subject. Weight and height were determined using standard techniques and following the norms of the WHO. Food frequencyquestionnaire (FFQ) for mass and frequency as well as energy and nutritional components of dairy products intake were used. The results indicated that adolescents in urban area consumed statistically significant (p<0.05) higher amount of milk and dairy products. Higher intake of energy, protein and calcium from milk and dairy products among adolescents in urban area was also observed. Average intake of calcium according to recommendation (RDA) is adequate for sex and age among subjects in urban are. Lower calcium intake was observed among the girls. In terms of food types, higher fat content dairy products were consumed among adolescents in both living areas, while according to sex, girls mostly consumed less fat milk and dairy products. According to body mass index (BMI) adolescents in both living areas were nourished well.

Abstract	This study was performed in a group of adult vegetarians (N = 40) and matched non-vegetarian subjects (N = 40) in order to analyse differences in health-related biomarkers. Obtained results revealed differences in various biomarkers between subjects on a traditional mixed and vegetarian diet, indicating that vegetarians have a lower nutritional status of some nutrients (Ca, Cu and Zn, and vitamins B12 and D) accompanied with a lower antioxidant defence system (glutathione) and higher homocysteine and genome damage (micronuclei and DNA strand breaks), along with shorter telomeres. This suggests that the supplementation of animal derived nutrients to this particular dietary group would be beneficial for the improvement of some measured health-related biomarkers. However, the level of certain toxic metals (As and Hg) was higher in non-vegetarians. The presented multi-biomarker approach implies the necessity of evaluating a large number of different health-related biomarkers in order to obtain clear insight into dietary preferences and health outcomes.

Abstract	As an important determinant of osteoporotic fracture risk, peak bone density tends to be higher in men than in women. The aim of this study was to see whether young men and women differed in the time and skeletal region of peak bone density. We also investigated the influence of diet and physical activity on bone mass. The study group included 51 male and 75 female students aged 19 to 25 years. Bone mineral density was measured for the spine, total femur, and the distal third of the radius using dual energy x-ray absorptiometry. Dietary data were obtained using a specially designed semiquantitative food frequency questionnaire. Bone mineral density (BMD; g cm(-2)) was higher in boys than in girls at all measured sites, while bone mineral apparent density (BMAD; g cm(-3)) was higher in girls. Age negatively correlated with bone mineral density in all measured sites except in the boys' spine. Sodium, protein, and fibres were nutrients that significantly correlated with bone mineral density. The study suggests that boys achieve peak bone density later than girls, and that this delay is the most prominent in the spine. In our study group, this difference could not be explained by different nutrition or the level of physical activity.

Abstract	Metabolic parameters were determined in fasting blood serum, fasting first morning urine, and 24-hour urine of male patients with recurrent calcium oxalate stones (N = 26, age 39.1 +/- 6.2 years) as well as in male healthy controls (N = 18, age 35.0 +/- 7.1 years), recruited from the eastern part of Croatia. The 24-hour urinary calcium excretion was significantly higher (p < 0.01) for patients (5.6 +/- 2.5 mmol) than for controls (3.7 +/- 1.9 mmol), but potassium excretion was higher (p < 0.01) for controls (74.5 +/- 33.8 mmol) than for patients (49.2 +/- 15.7 mmol). The mean ionic activity product of calcium and oxalate ions, IAP(CaOx), calculated from the fasting first morning urine parameters, was 25% higher for patients than for controls, but the difference was not statistically significant (p > 0.05). Very strong correlation (r = 0.97) was obtained between IAP(CaOx) values and calculated Ogawa indices that were recommended for estimating the potential risk for calcium oxalate stone formation.
