Cyril &amp; Methodius University, Skopje, (North Macedonia) filled out the Motivated Strategies for Learning Questionnaire. In this questionnaire-based, cross-sectional, observational study emphasis was given to the first-year students (n=109). Cohort distribution was determined according to scores expressing the level of practicing instruments of each learning strategy. Percentiles and lo­west scores were used for tracing the least adopted strategies.</p> <p><strong>Results: </strong>Majority of the first-year students (52.49%) use learning strategies at medium level, 26.60% at high and 20.89% at low level. For three subscale areas the percentile of students practicing at low level is especially high (39.45% for critical thinking, 40.36% for peer learning and 36.69% for help seeking). For these subscales also students’ scores have the lowest values.</p> <p><strong>Conclusion:</strong> Our first-year students use a different level of learning strategies. As 20.89% of students practice less than 55% of the instruments of each learning strategy and critical thinking, peer learning and help seeking (shown to be less adopted) are basic instruments for deeper and effective learning, the need to assist the first-year students in better adopting lear­ning strategies is obvious.</p> 2021-12-30T00:00:00+00:00 Copyright (c) 2021 Academic Medical Journal https://amj.mk/index.php/amj/article/view/42 NON-METRIC VARIATIONS OF THE AXIAL SKELETON BONES IN MEDIEVAL SKELETONS FROM VINICA FORTRESS (VINICHKO KALE) 2021-11-13T06:57:57+00:00 Niki Matveeva nikimatveeva@gmail.com Fanica Veljanovska fveljanovska@yahoo.com Julija Zhivadinovik zivadinovikj@yahoo.com Biljana Zafirova zafirovab17@gmail.com Elizabeta Chadikovska elizabeta.chadikovska@medf.ukim.edu.mk Ace Dodevski a.dodevski@medf.ukim.edu.mk Biljana Trpkovska biljana.trpkovska@medf.ukim.edu.mk Biljana Bojadzieva Stojanoska bojadzievab@medf.ukim.edu.mk <p>The majority of researchers use cranial and infracranial non-metric traits as separate entities in their investigations of the past populations. We decided to focus our investigation on the axial skeleton non-metric traits, consisting of components such as cranial and vertebral column skeleton. The main goal of our study was to gain some insight into the expression of axial skeleton non-metric traits in a medieval population sample. We investigated 72 well preserved skeletons from the medieval period documented collection (11-12 century AD) in order to examine axial skeleton non-metric traits. The skeletons belonged to individuals aged 20 to 65 years, of both sexes, exhumed from the necropolis Vinichko Kale.</p> <p>Analysis of cranial non-metric traits in our population sample showed a high prevalence of occipital bone cranial traits, such as os apicis (13.9%) and torus occipitalis (20.8%). Among vertebral column non-metric traits, a high prevalence of cervical spine traits, such as ponticulus posterior atlantis (11%), foramen transversarium partitum - FTP (33.3%), foramen transversarium apertum - FTA (13.9%) and cervical ribs (13.9%) was noted. Our findings of skeletal non-metric traits in the medieval population can provide additional knowledge in the skeletal growth and development in general.</p> <p> </p> 2022-01-10T00:00:00+00:00 Copyright (c) 2021 Academic Medical Journal https://amj.mk/index.php/amj/article/view/57 EFFECTS OF RAMADAN FASTING ON SOME BIOCHEMICAL PARAMETERS 2021-12-13T20:09:10+00:00 Katerina Tosheska-Trajkovska katerina.tosheska.trajkovska@medf.ukim.edu.mk Melda Emin melda.emin@medf.ukim.edu.mk Irena Kostovska irena.kostovska@medf.ukim.edu.mk Ampova Hristina hristina.ampova@medf.ukim.edu.mk Elena Petrushevska-Stanojevska elena.ps@medf.ukim.edu.mk Coshkun Kerala kerala.coshkun@medf.edu.ukim.mk Dragan Cibrev dragan.cibrev@medf.edu.ukim.mk Natasha Toseska-Spasova ntoseska@stomfak.ukim.edu.mk Ognen Kostovski ognen.kostovski@medf.ukim.edu.mk Svetlana Cekovska svetlana.cekovska@medf.ukim.edu.mk Jasna Bogdanska jasna.bogdanska@medf.ukim.edu.mk Sonja Topuzovska sonja.topuzovska@medf.ukim.edu.mk <p><strong>Introduction:</strong> Holy month Ramadan lasts for about 29-30 days. It is mandatory for all adult individuals of the Islamic faith to fast during the holy month of Ramadan. During this period, healthy Muslims do not eat or drink (i.e., total abstinence from food and fluids) and refrain from tobacco, daily from pre‑dawn until dusk.</p> <p><strong>Materials and Methods:</strong> The present study included healthy adult male and female Muslim volunteers from different towns in the Republic of North Macedonia. The number of subjects in the study was 195. Blood samples from all subjects were collected twice during the study - once 2-3 days prior to the beginning of Ramadan and then again, the last day of Ramadan fasting. The following biochemical parameters were taken into consideration: total cholesterol, triglycerides, HDL cholesterol, glucose, insulin, total proteins, albumin, total and direct bilirubin, urea, creatinine and uric acid.</p> <p><strong>Results:</strong> It was observed that compared to pre‑fasting levels, total cholesterol (TC) and triglycerides (TG) were significantly decreased (P=0.000) and high‑density lipoprotein cholesterol (HDL‑C) level had significantly increased (P=0.000); total proteins were significantly increased (P=0.000); albumins were significantly increased (P=0.004); urea was significantly increased (P=0.004); total and direct bilirubin were significantly increased (P=0.000), glucose was significantly increased (P=0.000); there was no change in insulin levels (P&lt;0.1)</p> <p><strong>Conclusion:</strong> This study showed that Ramadan fasting has an effect on biochemical parameters. We can conclude that reduction in total cholesterol and triglycerides along with a rise in levels of HDL‑C have beneficial effects on lipid profile post-Ramadan fasting period.</p> 2021-12-30T00:00:00+00:00 Copyright (c) 2021 Academic Medical Journal https://amj.mk/index.php/amj/article/view/53 COMPARATIVE ANALYSIS OF PREOPERATIVE AND POSTOPERATIVE DIAGNOSIS IN SKIN MELANOMA 2021-12-18T13:36:59+00:00 Lazo Noveski lazo_noveski@yahoo.com Boro Dzonov bdzonov@yahoo.com Elizabeta Mirchevska elizabetamircevska@yahoo.com Margarita Peneva mapeneva@yahoo.com Vladislav Gruev ado638@yahoo.com Jasmina Dobrevska jasmina.dobrevska@yahoo.com <p><strong>Introduction:</strong> Taking into account the increase in incidence and high mortality in advanced stages, early diagnosis is a prerequisite for successful treatment of melanoma.</p> <p><strong>The aim</strong> of this study was to determine the concordance between dermatological (with dermoscopy), surgical and pathohistological diagnosis in patients with a suspicious finding of skin melanoma.</p> <p><strong>Material and methods:</strong> A comparison between the clinical and pathohistological diagno­sis of patients of both sexes, of all ages, with a referral diagnosis of skin melanoma was made.</p> <p><strong>Results:</strong> Out of a total of 535 analyzed cases, 469 (87.5%) had preoperative dermato­lo­gical findings.

The aim of this study was to retrospectively investigate the spectrum of fungi responsible for skin and soft tissue infections over a 3-year period, and to compare the results with those from other parts of the world.</p> <p><strong>Material</strong> <strong>and</strong> <strong>methods:</strong> The study was performed during a 3-year period (2017-2019) and included analysis of 11,863 wound samples, which were obtained from patients hospital­lized at the University Clinics of the “Mother Theresa” campus, City hospital ”8<sup>th</sup> September” and University Clinic for Surgical Diseases “St. Naum Ohridski” in Skopje. All specimens were analyzed by standard mycological methods at the Institute of Microbiology and Parasitology.</p> <p><strong>Results: </strong>Growth of fungi was confirmed in 5.5%, 5% and 6.2% of the positive speci­mens, during a 3-year period, respectively. <em>C</em><em>. </em><em>albicans</em> was a predominant yeast (67.6%, 63%, 63.2% in 2017, 2018 and 2019, respectively). Molds were represented by <em>Aspergillus </em>confirmed in 3, 4 and 5 specimens, and <em>Fusarium</em> was confirmed in 2, 3 and 3 specimens during the 3-year period, respectively. <em>Mucor </em>was detected in 3 patients, in 2019 only.</p> <p><strong>Conclusion:</strong> Species identification of fungal microbes in wound specimens revealed that <em>Candida</em> species was the most predominant species, followed by <em>Aspergillus</em> and non-<em>Aspergillus</em> molds. It is crucial for every institution that treats patients with wounds to be aware of fungi as possible etiological agents of wound infections.</p> 2021-12-30T00:00:00+00:00 Copyright (c) 2021 Academic Medical Journal https://amj.mk/index.php/amj/article/view/46 SAPS 2 SCORE VALID PARAMETER FOR OUTCOME IN SEVERE INFLUENZA 2021-11-20T17:45:13+00:00 Marija Cvetanovska mcvetanovska2001@yahoo.com Ilir Demiri ilirdemiri@yahoo.com Krsto Grozdanovski kgrozdanov@hotmail.com Katerina Spasovska kspasovskamk@yahoo.com Vlatko Cvetanovski vcvetanovski@yahoo.com <p>The <strong>aim</strong> of study was to identify the<strong> </strong>significance of SAPS 2 score admission values on outcome in severe influenza.</p> <p><strong>Materials and methods:</strong> The investigation was prospective, group comparison, con­duc­ted at the University Clinic for Infectious Diseases, Skopje in a three-year period. The study included adult patients with severe influenza divided in two groups, survived and deceased. Demographic, clinical and biochemical data were noted on admission. The variables of the univariate analysis that showed a significant difference in terms of the outcome were used for creating multivariate logistic and regression analysis of the outcome as dependent factors. The independent predictors for lethal outcome in severe cases of influenza were identified by using logistic regression.</p> <p> <strong>Results:</strong> The study included 87 patients with clinical and laboratory confirmed severe influenza divided in two groups: survived (n=75) and deceased (n=12). The overall mortality was 13.79%. Multivariate analysis conducted on admission identified SAPS II score (p=0.048) as independent predictor of the outcome in severe influenza. The increase of the SAPS II score in one point increased the chance of death in patients with influenza by 1.2% (OR=1.12 95% CI 1.01-2.976).</p> <p><strong>Conclusion:</strong> In our study the SAPS II score has been identified as an independent va­riab­le, which has predicted the outcome in patients with severe influenza on hospital admission. The early identification of the outcome predictors in patients with severe influenza will ensure implementation of adequate medical procedures, and also, it will contribute to decreasing the mortality of this disease.</p> 2021-12-30T00:00:00+00:00 Copyright (c) 2021 Academic Medical Journal https://amj.mk/index.php/amj/article/view/48 BONY COCHLEAR NERVE CANAL IN CHILDREN WITH BILATERAL PROFOUND SENSORINEURAL HEARING LOSS – A PILOT STUDY 2021-11-22T17:53:02+00:00 Marija Dokoska m_dokoska@yahoo.com Marina Davceva-Chakar marinacakar@yahoo.com Sonja Nikolova sonikmk@gmail.com Gordana Kiteva-Trencevska g.kiteva.trencevska@gmail.com <p><strong>Introduction:</strong> The aim of this study was to evaluate the width of the bony cochlear nerve canal (BCNC) in children with congenital sensorineural hearing loss (SNHL) and "normal" findings on thin section temporal bone CT.</p> <p><strong>Material and methods: </strong>The width of the BCNC was retrospectively evaluated in two groups of patients. The study group included 11 children (22 bone canals) aged 2-12 years, with congenital, bilateral SNHL who underwent cochlear implantation (CI) from July to De­cember 2019 and no abnormalities of the inner ear were detected on their preoperative CT scans. Eleven patients (22 bone canals), aged 3-10 years, in whom no sensorineural hearing loss had been diagnosed were taken as controls and CT scan of the temporal bone was perfor­med for another reason - suspected acute mastoiditis, chronic otitis media, or perforation of the tympanic membrane. Axial sections of their CT scans were used to measure the width of the BCNC.</p> <p><strong>Results:</strong> BCNC width values in patients with bilateral, profound sensorineural hearing loss ranged from 1.0 to 2.3 mm and the mean value was 1.5±0.3 mm. In patients with normal hearing, the values for the canal width were higher, with mean value of 2.1±0.3 mm.</p> <p><strong>Conclusion: </strong>The results obtained showed that the width of the BCNC in children with bilateral, profound sensorineural hearing impairment was significantly smaller than in the con­trol group with normal hearing for p &lt;0.05 (t-test=6.62912, p=0.000000).</p> 2021-12-30T00:00:00+00:00 Copyright (c) 2021 Academic Medical Journal https://amj.mk/index.php/amj/article/view/43 CCNG1 AND FDXR GENE EXPRESSION LEVELS AFTER RADIATION THERAPY IN BREAST CANCER PATIENTS 2021-11-20T06:24:34+00:00 Katerina Trenceva ktrenceva@yahoo.com Aleksandar Eftimov aleks.eftimov@yahoo.com Aleksandar Petlichkovski aleksandar.petlichkovski@medf.ukim.edu.mk Zlatko Jakovski drjakovski@gmail.com Sonja Topuzovska sonjatopuzovska@yahoo.com <p><strong>Introduction: </strong>Radiation biomarkers represent parameters which, through their quan­ti­fication, reflect the interaction of the biological system with ionizing radiation (IR) as а physical agent in the environment and are object of study of the biological dosimetry. Of all identified radioresponsive genes that consist “gene signatures” of IR, the gene for ferredoxin reductase, FDXR, is prominent with its promptness and relevance in estimation of exposition to IR. It is also known as adrenodoxin reductase. The gene for CCNG1 represents another <em>in vitro </em>and <em>in vivo </em>validated radiation biomarker involved<strong>. </strong></p> <p><strong>Materials and methods: </strong>In this non-randomized, controlled open-trial clinical study, 57 patients with diagnosed breast cancer and 50 healthy individuals were included. Isolation of RNA from 3 mL peripheral blood and gene expression analysis with qRT-PCR were performed for detection of expression of FDXR and CCNG1 genes.</p> <p><strong>Results: </strong>A statistically significant difference in the threshold cycle was confirmed for FDXR and CCNG1 in the analyzed period between 24 and 48 h after radiation.</p> <p><strong>Conclusion: </strong>Gene expression is emerging as a highly powerful readout for biodosimetry. Exposure to IR leads to many cellular responses including modification of gene expression. Many genes have been reported to be radiation-responsive at the transcriptional level and monitoring of their expression in blood samples can potentially be used for rapid, minimally invasive high-throughput biological dosimetry purposes.</p> 2021-12-30T00:00:00+00:00 Copyright (c) 2021 Academic Medical Journal https://amj.mk/index.php/amj/article/view/49 HYPOTHYROIDISM AND ITS ASSOCIATION WITH CHANGES IN THE LIPID PROFILE 2021-11-25T14:28:35+00:00 Maja Jazheva Davchevska maja_jazeva@yahoo.com Vesela Maleska Ivanovska vesela.maleska@yahoo.com Vesna Velic Stefanovska vesnamia@t.mk <p><strong>Introduction: </strong>Thyroid gland dysfunction is presented as overt or subclinical hypothy­roidism and has repercussions on patient’s lipid profile.</p> <p><strong>Aims:</strong> To present patients lipid status with hypothyroidism versus a control group and to determine an association of thyroid status elements with lipid parameters.</p> <p><strong>Material and methods:</strong> This case-controlled retrospective study included a sample of 82 patients, examined group (N=56), who were divided into two subgroups according to the established TSH level (ТЅН&lt;4ulU/ml and ТЅН&gt;4ulU/ml) and a control group (ТЅН&lt;4ulU/ml) (N=26). We analyzed the parameters of the thyroid function (TSH, FT4, FT3, anti-TPO) and se­lec­ted lipid status parameters (cholesterol, triglycerides, HDL-cholesterol and LDL-cholesterol).</p> <p><strong>Results:</strong> The comparative analysis between the examined and the control group of patients, as well as between the two subgroups, found no significant difference in the lipid pa­ra­meter levels in relation to selected parameters of the lipid status. The performed correlation among the elements of the lipid status with the thyroid parameters determined a significant linear negative weak correlation between the fT4 and cholesterol, and between fT4 and triglycerides.</p> <p><strong>Conclusion: </strong>These three examined groups did not differ in lipid status, although dyslipidemia is an expected finding in untreated hypothyroidism. The statin therapy influenced on reduction of lipid fraction values ​​in all groups. Therefore, in newly diagnosed patients with hypothyroidism and dyslipidemia, before starting statin therapy, levothyroxine is recommended to be initially administered. Even under conditions of concomitant use of statins, cholesterol and triglyceride levels showed a negative correlation with fT4 and anti-TPO.</p> 2021-12-30T00:00:00+00:00 Copyright (c) 2021 Academic Medical Journal https://amj.mk/index.php/amj/article/view/55 IMPACT OF COVID-19 RELATED STRESSORS ON MENTAL HEALTH IN JUNIOR MEDICAL STUDENTS 2021-12-13T19:11:10+00:00 Sanja Manchevska sanjamancevska@gmail.com Jasmina Pluncevic Gligoroska jasmina.pluncevic@medf.ukim.edu.mk <p><strong>Introduction: </strong>Concern for mental health consequences in general population world­wide has been apparent since the start of the actual pandemic. <strong> </strong></p> <p><strong>Aim of the study</strong> was to assess the impact of COVID-19 related stressors on mental health in junior medical students during December 2020 COVID-19 related lockdown.</p> <p><strong>Material and methods:</strong> The investigation included 275 second-year medical students aged 19-28 years, from the Faculty of Medicine, Ss.
