Item type:Publication, Indicators of abdominal obesity: waist circumference and waist-to-hip ratio in adolescence of North Macedonia(Macedonian Association of Anatomists, 2021-04-02); ; ; ; Obesity in children and adolescents in the world is reaching a scale of an epidemic. It is considered the most widespread disease in children in many countries, especially in developed countries. The aim of this study was to define WC and WHR among Macedonian adolescents aged 11 to 14 years. A cross-sectional study was performed in 2013-2015, comprising a sample of 1267 adolescents of the Republic of Macedonia aged 11 to 14 years; 646 males and 621 females. Weight, height, body mass index (BMI), waist circumference (WC), hip circumference (HC) and waist-to-hip ratio (WHR) were measured and percentiles were calculated using Cole’s Lambda, Mu and Sigma (LMS) method. The relation between WHR and general obesity, as defined by the International Obesity Task Force, was investigated with receiver operating characteristic (ROC) analysis. The boys had statistically significant higher values in all anthropometric measures, except in HC where statistically significant gender differences were not found. BMI, WC, and HC increased with the age. The obtained reference percentile curves can be used temporarily for obesity screening in children and adolescents. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, ANATOMICAL VARIATIONS OF THE AORTIC ARCH BRANCHING PATTERN(Faculty of Medicine, Ss. Cyril and Methodius University in Skopje, 2018); ; ; ; Anatomical variations of the aortic arch and its branches are fairly common and can have important implications on prognosis and management of surgical interventions, as well as on radiological diagnostics and interventional radiology. The aim of this study was to present the anatomical variations in branching pattern of the aortic arch in a large group of patients using CTA and consequently to determine their prevalence in our population. The study population included 1000 patients with referral diagnoses requiring CTA chest radiography, which visualizes the aortic arch. The course of the aortic arch was clearly observed in all of the 1000 patients. The anatomic features of the aortic arch itself and supra-aortic vessels were analyzed, and anatomical variations were recorded on each CT image. The results showed that 89.3% of the cases had the usual branching pattern of the aortic arch. The most common variation was aortic arch with two branches, with left common carotid artery arising from brachiocephalic trunk (7.9%). Separate origin of the left vertebral artery between the left common carotid artery and the left subclavian artery was present in 2.8% of cases. The knowledge of the anatomy of the aortic arch and its branches and the awareness of vascular variations is an imperative in diagnostic procedures and in planning surgical interventions during clinical practice. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Waist circumference, waist-to-hip ratio cut-off points to predict obesity and metabolic syndrome among student population in skopje, North Macedonia(Faculty of Medicine, Ss. Cyril and Methodius University in Skopje, 2021-06-21); ; ; ; Abdominal obesity is the most frequently observed component of metabolic syndrome. Any anthropometric measure is only the first step in identifying people at ‘early health risk’. This study aimed to determine a cut-off point of selected anthropometric indicators and to analyze the prevalence of normal weight obesity and abdominal obesity among university students. The study included 839 healthy students aged 18-20 (411 males and 428 females) from the Ss. Cyril and Methodius University in Skopje, R. North Macedonia. The following anthropometric parameters were measured: weight, height, two circumferences (waist WC and hip HC) using a standard protocol. The following indices were taken into consideration: Body Mass Index (BMI), WC and Waist-to-Hip Ratio (WHR). The prevalence of obesity across BMI cut-off points among Macedonian students was 22.22%. In the underweight group, the number of female students was significantly higher (12.61% vs 2.19%), while in the overweight and obesity group a higher percentage of male students was observed (27.5% vs 9.11% and 6.81% vs 1.41%). Prevalence of abdominal obesity according to WC and WHR cut-off among Macedonian students were: female had the prevalence of abdominal obesity (overweight and obese) of 25.47% WC and WHR 43.23%, respectively. Both cut-off points for the males were 34.55% WC and 52.81% WHR. However, the Macedonian cut-off points for WC and WHR showed a higher prevalence of abdominal obesity among males. These results and determination of BMI, WC, WHR cut-off values can be used for the prediction of consequences associated with obesity. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Somatotype in 11 years old Macedonian adolescents(Macedonian Association of Anatomists and Morphologists, 2018-04-12); ; ; ; Kavecan, IvanaObjectives. The aim of this study was to evaluate sex and ethnic differences of somatotype in Macedonian adolescents at the age of 11 years. Subjects and Methods. In this study 315 adolescent students (167 males and 148 females), from Macedonian and Albanian nationality at age of 11 years were included from primary schools in two cities: Skopje and Strumica in R. Macedonia. Ten anthropometric parameters were measured using standard equipment and measurement technique to assess the somatotype according to Heat–Carter somatotyping method. Results. Although there were not significant sex and ethnic differences of somatotype components between the groups at the age of 11 years, from the obtained results we concluded that males and females of Macedonian ethnic group had higher values for endomorph component than their Albanian pears, who had higher values for mesomorph and ectomoph component. Conclusion. Ethnic group should be taken in mind for easier evaluation and understanding of differences in anthropometric parameters of growth and body composition in Macedonian adolescents. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Morphologic characteristics of sacra associated with assimilation of the last lumbar vertebra(VM Media sp. z o.o. VM Group sp.k., Grupa Via Medica, 2016); ; ; Background: The impact of lumbosacral transitional states on biomechanics of load transmission between the spine and the legs has been sporadically reported. The aims of the study were to identify morphostructural alterations of sacra associated with assimilation of the last lumbar vertebra and to analyse them in the light of their biomechanical impact. Materials and methods: Linear dimensions of sacrum, its body and base and articular surfaces were measured in 31 normal and 41 transitory sacra. Nineteen sacra presented articular and 22 osseous fusion of the last lumbar vertebra. Measured parameters were compared between normal sacra and the two variations of transitory sacra. Results: Sacra with articular fusion of the last lumbar vertebra showed more pronounced concavity of the sacral curvature and wider than long sacral bodies. The first sacral segment was modified, broaden, ventrally wider and elevated. Almost the whole segment bore at its sides auricular surfaces. Very small portion of the segment was non-articular with less pronounced wedging. Sacra with osseous fusion of the last lumbar vertebra showed similar concavity of the sacral curvature as normal sacra, but longer than wide sacral bodies. The ventral sloping half of the newly formed first segment bore auricular surfaces. The non-articular part was enlarged with pronounced wedging. Conclusions: The term "sacralisation" includes both types of transitory sacra with mutually different morphostructural characteristics in contrast to the normal sacra. Analysis of these morphologic variations may help in understanding the different biomechanical properties and patterns of load transmission. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Anatomy of coronary sinus ostium(VM Media sp. z o.o. VM Group sp.k., Grupa Via Medica, 2016); ; ; Background: The coronary sinus is the main cardiac vein and it has become a clinically important structure especially through its role in providing access for different cardiac procedures. Materials and methods: The study was carried out on 100 randomly selected adult human cadaver hearts fixed in 10% formalin. The transverse and craniocaudal diameters of the coronary sinus ostium (CSO) were directly measured. The presence of the Thebesian valve was noted and the anatomical details of the valve were documented in each case in terms of the shape and extent of coverage of the CSO. Results: Considerable variations in the diameter of the CSO were observed. The mean craniocaudal diameter of the CSO was 8.1 ± 1.51 mm, and the mean transverse diameter was 7.67 ± 1.72 mm. Heart specimens without Thebesian valve tended to have larger ostia. The mean craniocaudal diameter and the mean transverse diameter of the CSO were statistically larger in the specimens without Thebesian valves (p = 0.000 and p = 0.001, respectively). Conclusions: The Thebesian valves were observed in 86 hearts, and a wide variety of their morphology was seen. The majority of the Thebesian valves were semilunar in shape (74.42%). The extent to which the valve covered the ostium was variable, including remnant valves that covered < 15% of the CSO (35%), and valves that were large and covered at least 75% of the CSO (22.09%). In 3 specimens the valve completely occluded the ostium. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Sex and age specific differences of anthropometric parameters in Macedonian adolescents(Macedonian Association of Anatomists and Morphologists, 2015); ; ; The aim of this study was to evaluate sex and age-specific differences of anthropometric parameters in Macedonian adolescents. This study included 1183 adolescent students (622 males and 561 females) at the age of 15 to 18 years. Anthropometric parameters, which define longitudinal and transversal measures of skeleton, were measured using standard equipment and measurement technique. BMI was calculated from body height and weight (kg/m2 ). Two skin-folds were measured: triceps and subscapular. We found a significant sex-specific difference for body height, weight, elbow and knee diameter at the age of 15 to 18 years in favour of boys. Height, weight and two transversal parameters had higher values in boys.Triceps and subscapular skin-folds as indicators for subcutaneous fat component and a valuable technique for evaluating the nutritional status had higher values in females in all age groups. Sex-specific differences were registered for triceps skin-fold at the age of 15 to 18 years, and for subscapular skin-fold at the age from 15 to 17 years in favor of females. Populations share their own genetic background and environmental factors, so anthropometric characteristics of the body of Macedonian adolescents can be used as criteria for the assessment of growth and nutrition within this group. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Anatomy and variations in the origin of the vertebral artery(Macedonian Association of Anatomists and Morphologists, 2011); ; ; ; The vertebral artery (a. vertebralis, VA) is classically described as the first branch of the ipsilateral subclavian artery (a. subclavia), but multiple variations in the origin of that vessel have been reported in the literature. This examination was made on 110 unselected human hearts without pathoanatomical changes, obtained after autopsy of newborns, fixed in 10% formaldehyde. Standard anatomical methods, inspection and dissection were used for the analyzing of the origin of a. vertebralis. The analysis showed that 102 of the specimens (92.7%) had the usual pattern of the aortic arch and its branches, with the usual topographic relations. In three of the specimens (2.7%) a. vertebralis sinistra had a separate origin between a. carotis communis sinistra and a.subclavia sinistra. In one specimen a. vertebralis sinistra had a separate origin as the fourth branch between a. carotis communis sinistra and a. subclavia sinistra and there was a fifth branch originating distal to a. subclavia sinistra.
