Objectives: The purpose of the present study was to assess neck-to-height ratio (NtHR) and its possible association with other anthropometric measures of obesity and blood pressure (BP) values in Bosnian university students stratified by new 2017 American College of Cardiology/American Heart Association Task Force hypertension (HT) guidelines.Methods: The present study included 417 subjects with median age 20 (19-21) years that were divided into normal BP, elevated BP, stage 1 HT, and stage 2 HT groups based on BP measurements using auscultatory methods. Standard anthropometric indices including neck circumference (NC) were measured. NtHR (cm/m) was calculated in each participant based on the NC and height. Differences between groups were assessed by Kruskal-Wallis followed by Man-Whitney test and correlations were determined by Spearman test.Results: The prevalence of elevated BP was 19.2%, stage 1 HT 21.6%, and stage 2 HT 11.0 %. NtHR was highest in the stage 2 HT group. NtHR correlated significantly with all anthropometric measures in all groups. No correlation between NtHR, systolic BP, and diastolic BP was found, except in the stage 1 HT group, where a significant correlation between NtHR and systolic BP was uncovered.Conclusions: Based on the observed correlations between NtHR and standard measures of obesity, NtHR could be included in clinical practice, since it is simple and does not induce discomfort. The high prevalence of elevated BP found in the present study suggests HT prevention requires the implementation of programs aimed at promoting healthy dietary habits, physical activity, as well as effective stress management and coping mechanisms.

Abstract Objective. The present study assessed the impact of type 2 diabetes mellitus (T2DM) duration on the serum asymmetric dimethylarginine (ADMA) and C-reactive protein (CRP) concentration in Bosnian patients. Methods. Participants for this cross-sectional study were randomly selected from the Family Medicine Clinic (Sarajevo, Bosnia and Herzegovina). Serum ADMA concentration was determined by ELISA. Serum high-sensitivity (hs-CRP) was determined by particle-enhanced immunonephelometry. ANOVA test followed by Scheffe post-hoc test or Kruskal-Wallis test followed by Man-Whitney test were used for statistical analysis. Results. The study included 38 patients in up to 10 years diabetes duration (≤10 years T2DM) group, 22 patients in greater than 10 years diabetes duration (>10 years T2DM) group, and 60 controls. Serum ADMA concentration in the >10 years T2DM group (1.81±0.15 μmol/L) was significantly higher compared to serum ADMA concentration in the ≤10 years T2DM group (1.38±0.41 μmol/L; p<0.001) and in controls (0.62±0.15 μmol/L; p<0.001). A significant difference in serum ADMA concentration was found between the <10 years T2DM group and the controls (p<0.001). The serum CRP concentration in the >10 years T2DM group [5.95 (4.20–9.12) mg/L] was significantly higher compared to serum CRP concentration in the <10 years T2DM group [2.35 (1.40–4.30) mg/L; p<0.001] and controls [0.85 (0.50–1.30) mg/L; p<0.001]. Significant difference in serum CRP concentration was observed between the <10 years T2DM group and controls (p<0.001). Conclusions. The present study showed an increase in the serum ADMA and CRP concentrations with the advancement of T2DM. These results suggest that ADMA and CRP may serve as indicators of endothelial dysfunction and chronic low-grade inflammation progression in patients with T2DM. Larger prospective studies are required to confirm the observed findings.

Aim To evaluate the efficacy (rate of recanalization) of therapy with novel oral anticoagulants (NOAC; rivaroxaban, apixaban) compared to conventional treatment (low molecular weight heparin - LMWH and vitamin K antagonist) in the treatment of deep vein thrombosis (DVT) of the proximal segments of lower extremities. Methods The first group consisted of patients diagnosed with DVT and treated with NOAC (n = 100), while the second group consisted of patients diagnosed with DVT, who were treated by conventional treatment (low molecular weight heparin and vitamin K antagonists) (n = 100). In the first group, NOAC was included in the initial treatment. Patients in the second group were treated with LMWH for four days, and on the fifth day vitamin K antagonist was included in therapy, international ratio (INR) was titrated to therapeutic values (2.0-3.0), and then low molecular weight heparin was excluded from the therapy. Results There was a statistically significant difference in the estimated values of free lumen of the blood vessel between the examined groups after 30 days (p=0.0001), after 90 days (p=0.0001) and after 180 days (p=0.0001). After 180 days, the average free lumen values in the NOAC group were 85% (81-89%), which was significantly higher than the free lumen values in the second group, 73% (69-79%). Conclusion The use of NOAC represents more efficient treatment of DVT comparing to vitamin K antagonists.

Aim To present haemoglobin and ferritin parameters in donors to highlight the importance of serum ferritin testing for the purpose of evaluating iron depots in order to make recommendations for preserving a population of blood donors. Method A prospective study was conducted on 80 blood donors divided in two groups: group I (regular donors, n =40) and group II (irregular donors, n=40). Haemoglobin and ferritin were measured twice every 45 days, before two consecutive blood donations. Results By measuring haemoglobin and ferritin values before donation in both groups, a decrease of initial ferritin value in Group I relative to Group II was observed (without statistical significance). A significant decrease was found between repeated measurements for both parameters in both groups, indicating equal intensity of the decline in value regardless of a donor status. Measurement of ferritin before and after donation revealed statistically significant loss of ferritin in all examinees (p=0.011). The decline in haemoglobin after donation, although significant, did not fall below the reference value for donation in either women or men. Conclusion Results indicate the need for periodic monitoring of the plasma value of ferritin in voluntary donors who donate blood more than twice a year and the possible oral supplementation with iron.

Background Altered levels of many hematological parameters have been directly associated with diabetes in adults, while studies on children with type 1 diabetes mellitus are lacking. The aim of this study was to determine hematological indices in diabetic Bosnian children in comparison to healthy controls as well as to correlate their levels to blood glucose and hemoglobin A1c. Methods 100 healthy and 100 children with type 1 diabetes mellitus (age 1-18) were included in this study. Complete blood count, hemoglobin A1c, and glucose were tested. Results were analysed by IBM SPSS Statistics version 23. Results Significant differences (p<0.05) between healthy and diabetic children were found in relation to HbA1c, glucose, mean platelet volume, the number of white blood cells and erythrocytes, hematocrit, hemoglobin and MCH values. No gender differences or significant age differences were seen for hemoglobin, hematocrit, and MCV, while platelets, MPV, and MCH differed by age only in healthy children. When diabetic children were classified according to HbA1c levels, significant differences were seen for erythrocyte count and hematocrit value (p=0.013 and 0.019, respectively). The number of erythrocytes and white blood cells correlated significantly with HbA1c (p=0.037 and 0.027, respectively). Conclusions Lower levels of erythrocytes, hematocrit, and hemoglobin in diabetic compared to healthy children indicate possible development of anemia, while higher MCV, MCH, and MPV values indicate an alteration in erythrocyte morphology. Hematological indices could be a useful inexpensive tool in the diagnosis and follow up of type 1 diabetes in children.

Introduction Acute appendicitis (AA) is the most common surgical condition of the abdomen in children. The aim of this study was to analyse the possible use of the neutrophil-to-lymphocyte ratio (NLR) in the diagnosis and prediction of AA complications in children. Material and methods We included 170 AA patients under 15 years of age, who were divided into the following groups: Group 1 – non-operated patients with AA, and Group 2 – patients who underwent appendectomy. Based on pathologic grades of AA, Group 2 was subdivided into: Group A – phlegmonous, Group B – gangrenous, and Group C – perforated AA. NLR was calculated as the absolute neutrophil count divided by the absolute lymphocyte count. Results In Group 2 NLR was significantly higher than in Group 1 (5.5 (1.9–9.9) vs. 2.3 (1.2–3.7); p < 0.001). A significant difference in NLR was found between Group C and Group A (p < 0.001), and as well as between Group B and Group A (p = 0.001). The determined optimal cut-off value of NLR in differentiating Group 1 vs. Group 2 was ≥ 3.48 (p < 0.001). In differentiating Group A from Group C the optimal cut-off value of NLR was ≥ 5.61 (p < 0.001). Furthermore, optimal cut-off value of NLR in differentiating Group A from Group B was ≥ 5.45 (p = 0.001). Conclusions The obtained results suggest that NLR could be used as a simple and reliable test in the diagnosis and prediction of AA complications in children. However, to draw definite conclusions on the predictive power of NLR as a marker of AA large multicentric studies are required.

Introduction: Neuralgic amyotrophy (NA) or Parsonage Turner syndrome is a clinical syndrome characterized by sudden attack of neuropathic pain, motor weakness and sensory loss that could be more or less clinically present. Different interpretations regarding the differential diagnosis, symptoms, cause and treatment were given till now. Aim: We report our experience with a 66-year-old male who had a sudden pain attack and palsy in shoulder region, without sensory loss, and associated calcific tendinitis of rotator cuff and degenerative changes in cervical spine. Case report: Patient came to our hospital with strong pain in shoulder area and signs of frozen shoulder. Active abduction and anteflexion was only to 30 degrees. He experienced the intense pain with visual analogue scale (VAS) 10/10 a night before, during his sleep. No trauma. Neurontin (gabapentin) was given to the patient. After 4 days, he felt better with abduction and anteflexion to 90 degrees. After 2 weeks VAS was 3/10, abduction and anteflection to 100 degrees. Conclusion: Neuralgic amyotrophy (NA) is a self-limiting inflammatory disorder usually with idiopathic etiology. The condition can be challenging to treat since many associated symptoms and diagnostic tests and procedures may mimic NA. In that case, accurate differential diagnosis is essential.

Introduction: Poor glycemic control, assessed by higher glycated hemoglobin (HbA1c) levels, is associated with greater risk of diabetic complications. Aim: The aim of this study was to assess the association of triglyceride - to - HDL cholesterol (TG/HDL-C) ratio and triglyceride glucose (TyG) index with HbA1c and to evaluate their potential role as predictors of glycemic control in patients with diabetes mellitus type 2 (DM2). Patients and methods: This cross-sectional study was conducted in Health Center Banovici and included a total of 113 patients with DM2 classified according to their HbA1c values in two groups: DM2 HbA1c <7% - DM2 patients with good glycemic control (n=39) and DM2 HbA1c ≥7% - DM2 patients with poor glycemic control (n=74). Anthropometric, biochemical parameters and blood pressure values were measured, while TG/HDL-C ratio and TyG index were calculated. Results: TG/HDL-C ratio and TyG index were significantly higher in DM2 HbA1c≥7% compared to DM2 HbA1c<7% group (p=0.003 and p<0.001; respectively). Both TG/HDL-C ratio and TyG index were positively associated with HbA1c levels (Rho=0.29; p=0.002; Rho=0.37; p<0.001; respectively). In linear regression analysis TG/HDL-C ratio and BMI, and also TyG index and BMI were significantly independently associated with HbA1c even after controlling for age, gender, diabetes duration and smoking. When we stratified patients according to BMI values, independent association between TG/HDL-C ratio and HbA1c remained significant only in normal weight subjects (OR 0.21; 95%CI: 0.05-0.37; β=0.65; p=0.017), while independent association between TyG index and HbA1c remained significant only in overweight and obese subjects (OR 0.063; 95%CI: 0.01- 0.12; β=0.24; p =0.027). Conclusion: TG/HDL-C ratio might be a useful predictor of glycemic control in normal weight, and TyG index in overweight and obese patients with DM2.

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.

Background: Multiple myeloma (MM) is a disease of B cell population with excessive secretion of immunoglobulins and presence of free light chains (FLCs) that are by products of immunoglobulin synthesis. Free light chains play crucial role in causing renal damage. Interleukine-6 (IL-6) supports the survival and/or expansion of MM cells by stimulating cells as well as by preventing programmed cell death. Aims and Objectives: The aim of this study was to evaluate serum and urine free light chains (FLC)measurement and compare with IL-6 levels in patients with different stages of Multiple Myeloma (MM) and control group of subjects and to determine their relevance in acute kidney injury occurrence. Materials and Methods: Recruitment of patients with MM (n=62) made the hematologist that followed clinical Solomon-Durie MM classification. Control group consisted of 20 healthy individuals. Results: Patients with MM and renal function injury had significantly higher concentration of urine κ chains compared to control group and group of MM without renal function injury (p<0.005), whereas this difference was not observed when the patients were divided into disease stages groups. Concentration of IL-6 was significantly higher in patients at MM steady stage compared to control group (p<0.001) and significant difference was also detected in patients with MM at relapse stage and control group (p<0.0005). Concentration of IL-6 in MM patients without renal function and with renal function injury was significantly higher compared to control group (p< 0.001; p<0.0005 respectively). Statistically significant correlation was determined between sera κ and urine κ chains (rho=0.437; p<0.01) as well as between urine λ and sera λ chains (rho=0.505; p<0.01) and between urine κ and urine λ chains (rho=0.364; p<0.01). Conclusion: Results showed that urine κ chains, sera κ chains and IL-6 are constructing a fine tuned net and point to conclusion that FLC and IL-6 are important for an early treatment response detection for patients with potentially reversible renal failure.

AN IMPACT OF DIABETES DURATION ON SERUM ASYMMETRIC DIMETHYLARGININE CONCENTRATION

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.

Significant correlation of NC with SBP (r=0.08; P=0.57), and with DBP (r=0.20; P=0.17) in young men was not determined. Likewise, in young women significant correlation of NC with SBP (r=0.08; P=0.54), and with DBP (r=0.09; P=0.49) was not observed. Conclusions: Results of the present study suggest possible use of NC measurement as a valid method of obesity assessment in young adults. Lack of an association between NC and blood pressure values requires additional investigation.
