Objective The association between the neck circumference (NC) and components of metabolic syndrome in different countries and ethnic groups has been insufficiently investigated. The aim of the present study was to assess the impact of gender on NC values and to determine whether NC correlates with standard anthropometric measures and blood pressure values in Bosnian young adults. Materials and Methods Study participants were recruited by the snowball method. The NC, body mass index (BMI), waist circumference (WC), systolic blood pressure (SBP), and diastolic blood pressure (DBP) were measured by trained personnel. Differences between the means were assessed by a Student's t-test. Coefficients of correlation were determined by Pearson's test. Results In young men (n=49), the value of NC was 37.71±1.79 cm, while in young women, (n=62) the value of NC was 32.23±1.83 cm (p<0.001). A significant positive correlation in both genders between the NC and BMI (r=0.70, p<0.001 in men; r=0.53,p<0.001 in women), and between the NC and WC (r=0.48, p<0.001 in men; r=0.38, p=0.01 in women), was found. A significant correlation between the NC and SBP (r=0.08, p=0.57), and DBP (r=0.20, p=0.17), in young men was not determined. Likewise, in young women, a significant correlation between the NC and SBP (r=0.08, p=0.54), and DBP (r=0.09, p=0.49), was not observed. Conclusion Our results suggest that the NC measurement can be used as a valid method in obesity assessment in young adults. A lack of association between the NC and blood pressure requires additional investigation.

Introduction: The main aim of the study was to examine the interdependence of values of the nutrition index, the use of medicaments, and alcohol consumption in the group of subjects with post-traumatic stress disorder (PTSD) and in control group without PTSD. Methods: To determine the interdependence of different indices of nutrition and the alcohol and drug consumption in both groups, the crosstab model was used. Results: In both of the tested groups, medicament users had higher average values for nutritional indexes compared to the subjects that are not the consumers of medicaments, but the confirmed differences were not statistically significant. The subjects with PTSD who consume alcohol had lower average values for nutritional indexes compared to the subjects who do not consume alcohol. In the control group, subjects who consumed alcohol had higher mean values for nutritional indexes than those who did not consume alcohol. Differences in the values of the nutrition index between alcohol and non-alcohol subjects were not statistically significant either in the PTSD group or in the control group. The subjects with PTSD had less average values of all the used nutrition indexes compared to the control group subjects, but the confirmed differences were not statistically significant. Conclusion: Our results indicate that medicaments use and alcohol consumption do not exert a statistically significant effect on the values of the nutrition index in any of the study groups. Possible concomitant use of drugs with the opposite effect on the monitored parameter (nitrazepam and amitriptyline vs. SSRI and bupropion) can lead to findings like this. We recommend further research to eliminate influence of pharmacodynamic effects of alcohol, drugs, and stress on the development of weight gain or loss.

Background: The femur is supplied princially by the diaphyseal nutrient artery which enters the bone throught the nutrient foramen. This supply is essential during the growing period, the early phases of ossification, and in different surgical procedures. The aim of present study was to examine the morphology and topography of the femur nutrient foramen to provide detalied data on such features.Methods: This was a cross-sectional-descriptive study in which we observed 50 femurs. We analysed the number and location of nutrient foramina, the length of the bone, the position of the nutrient foramen regarding to values of FI, correlation between number of nutrient foramen and length of femur, correlation between position of nutrient foramen and side of extremity to which femur belongs.Results: The double foramina were common in right (57.1%) and left (42.1%) femur, mostly located in medial lip of aspera line in right (64.3%) and on the lateral lip in left femur (68.4%), with statistically significant correlation, χ = 4.85; p = 0.03, p <0.05.  The foramina in left (89.5%) and right (96.4%) femur were commonly observed at their middle third, with no statistically significant correlation between position of foramen accordingly to Foraminal Index value and side of extremity on which femur belongs (p=0.56; p>0.05). There is positive correlation between length of right and left femur and number of foramina.Conclusions: The study provides data of the nutrient foramina on femur, which is helpful for clinicians to help preserve bone vascularization during surgery.

Aim To assess triglyceride - to high-density lipoprotein cholesterol (TG/HDL)-C ratio in patients with acute coronary syndrome (ACS) and to verify its association with renal dysfunction. Methods A cross sectional study included 85 ACS patients divided in two groups with (ACS - RD) and without (ACS-nRD) presence of renal dysfunction, and 35 healthy subjects. Blood pressure, blood glucose, C-reactive protein, urea, creatinine, eGFR and serum lipids levels (total cholesterol, triglycerides, LDL-C, HDL-C) was measured in all participants. Based on the values of the measured lipid fractions TG/HDLc ratio was calculated. Results Patients in ACS group had significantly lower HDL-C level (p<0.0005) but significantly higher TG level (p=0.046) and TG/HDL-C ratio (p<0.0005) than controls. There was a significant increase (p<0.0005) in TG/HDL-C ratio in ACS-RD group compared to ACS-nRD group. The ACS-RD group had significantly higher level of TG (p=0.001), serum urea (p=0.02) and creatinine (p<0.0005) compared to the ACS-nRD group. With a cut-off level of 1.135 TG/HDL-C ratio had a sensitivity of 77.6% and a specificity of 62.9% in distinguishing between ACS patients and healthy subjects. With cut-off value of 1.905 TG/HDL-C ratio had a sensitivity of 75.9% and a specificity of 78.6% in distinguishing between ACS patients with and without renal dysfunction. Conclusion This study confirms the reliability of the TG/HDLC ratio as a simple, low cost and useful marker in distinguishing between patients with ACS and healthy subjects and ACS patients with and without renal dysfunction.

AN IMPACT OF DIABETES DURATION ON SERUM ASYMMETRIC DIMETHYLARGININE CONCENTRATION

Introduction: Diabetes mellitus type 2 has become a global health-care problem of modern society due to a pronounced increase of prevalence to pandemic proportions and vascular complications. At present, glycated hemoglobin (HbA1c) is widely accepted as a measure of glycemic control in established diabetes. The aim of this study was to analyze the lipid profile in serum of patients with diabetes mellitus type 2, and its relationship with HbA1c levels. Methods: The observational cross-sectional study included 60 diabetic patients, 30 men, and 30 women, age 32–94 years. Patients were assigned into two groups based on HbA1c values; Group 1: HbA1c ≤ 7% (good glycemic control) and Group 2: HbA1c > 7% (poor glycemic control). We analyzed the concentration of glucose, HbA1c, and lipid profile including total cholesterol levels, triglycerides (TAG), low-density lipoproteins (LDL), and high-density lipoproteins (HDL). Results: Significantly lower values of glucose concentration, TAG and the ratio TAG/HDLc were obtained in the group of patients with good glycemic control. (p < 0.0005) Patients with good glycemic control had lower values of Castelli 1 and Castelli 2 index, and atherogenic index of plasma, compared to patients with poor glycemic control, but this difference was not significant. (p > 0.005) Our study revealed a significant positive correlation between HbA1c and triglyceride level (r = 0.375; p = 0.003) and HbA1c and ratio triglyceride/HDLc (r = 0.335; p = 0.009). Conclusion: HbA1c can also be used as a predictor of dyslipidemia in type 2 diabetics in addition to as a glycemic control parameter.

Background: Neck circumference (NC) is an index of subcutaneous adipose tissue distribution in an area of the upper part of the body. The aim of this study was to assess whether NC can be used as an indicator of central obesity and to determine the prevalence of central obesity in apparently healthy Bosnian young adults. Methods: Participants for this cross-sectional study were recruited using the snowball method. NC was measured in horizontal straight position by placing the top edge of a plastic tape only below the laryngeal prominence and perpendicular to the longitudinal axis of the neck, with the head positioned in the Frankfort horizontal plane. Body mass index, waist circumference (WC), and waist-to-hip ratio were taken following the WHO guidelines. Results: The study included 111 second year University of Sarajevo Dentistry students (49 students of male gender and 62 students of the female gender). Determined the optimal cutoff value of NC in the detection of central obesity based on WC values in healthy young participants of male gender was ≥37.45 cm (P < 0.001), while in healthy young participants of the female gender, it was ≥32.75 cm (P < 0.001). Based on the WHO guidelines for WC, central obesity was determined in 24.49% (n = 12) of male patients, and in 29.03% (n = 18) of female participants included in our investigation (P < 0.05). Conclusions: The results of the present study indicate that NC may be used as a screening tool for central obesity in healthy young adults. Prevalence of central obesity observed among student population suggests that there is a justified need for an implementation of healthy lifestyle programs in this population that would have preventive purposes.

Aim To investigate total homocysteine (tHcy) serum concentration in patients with probable vascular dementia (VD) and in agematched controls, as well as to determine an association between tHcy serum concentration and cognitive impairment in patients with probable VD. Methods Serum concentration of tHcy was determined by the Fluorescence Polarization Immunoassay on the AxSYM System. Cognitive impairment was tested by the Mini Mental Status Examination (MMSE) score. Body mass index (BMI) was calculated for each subject included in the study. Results Age, systolic, diastolic blood pressure and BMI did not differ significantly between the two groups. Mean serum tHcy concentration in the control group of subjects was 13.35 µmol/L, while in patients with probable VD it was significantly higher, 19.45 µmol/L (p=0.002). A negative but insignificant association between serum tHcy concentration and cognitive impairment in patients with probable VD was found. Conclusion Increased tHcy concentration in patients with probable VD suggests the possible independent role of Hcy in the pathogenesis of VD.
