METAKOGNICIJA I INTERNET KAO ALATI SAVREMENOG MEDICINSKOG OBRAZOVANJA- ANALIZA MEĐUSOBNE POVEZANOSTI

 Uvod: Unapređenje obrazovnog okruženja i podsticanje samostalnog aktivnog učenja studenata, nameće i pitanje razumevanja i razvoja strategija učenja kod studenata.
 Ključnu ulogu u tome ima metakognicija koju možemo definisati kao znanje i regulaciju sopstvenih kognitivnih procesa, odnosno sposobnost da se prate, kontrolišu i planiraju
 aktivnosti povezane sa učenjem i rešavanjem problema. Razvoj modernih tehnologija i korišćenje internet u procesu učenja je jedan od faktora koji utiču na metakognitivne
 sposobnosti. Za procenu metakognitivne sposobnosti koristi se „Upitnik za procenu metakognitivne svesnosti“,(engl. Metacognitive Awareness Inventory – MAI, koji je validiran
 za srpsku populaciju.
 Cilj rada: Ispitati povezanost potrebe interneta u toku studiranja sa komponentama metakognicije. 
Metode rada: Istraživanje je sprovedeno kao studija preseka u oktobru 2024. godine na Medicinskom fakultetu, Univerziteta u Prištini, Kosovska Mitrovica. Obuhvaćeni su svi
 student 3. godine medicine koji su pored klasične nastave iz Medicinske statistike i informatike imali i elektronsko učenje. Nastavni materijali su bili dostupni preko Moodle
 platforme i pripremljeni u vidu metakognitivni problemski baziranih modula u okviru Erazmus + projekta „Razvoj i implementacija metakognitivnih problemski baziranih
 modula u kursevima mešovite nastave u medicinskim naukama“, br. 101082790. Na stranici kursa bila je postavljena i srpska, validirana verzija MAI upitnika uz dodatak
 sociodemografski podataka i pitanja vezanih za proces studiranja. Upitnik je obuhvatao dve komponente. “Znanje o kogniciji”, (sa podkomponentama, deklarativno znanje,
 procedualno znanje, uslovno znanje) i “Regulaciju kognicije” (planiranje, strategija upravljanja informacijama, praćenje učenja i razumevanja, strategija za ispravljanje
 grešaka i evaluacija).
 Upitnik ima ukupno 52 stavke sa odgovorima ocenjenim Likertovom skalom sa 5 nivoa – od 1, „Uvek netačno“ do 5 „Uvek tačno“, a sabiranjem svih stavki u okviru jedne  
subkomponente dobijen je zbirni rezultat za datu potkategoriju metakognicije. Studenti su popunjavali upitnik pre pristupa nastavnim materijalima koji su se nalazili na kursu.
 Rezultati: Istraživanjem je obuhvaćeno 82 studenta, prosečne starosti 20,9±0,9. Ispitivani uzorak je činilo 32,9% osoba muškog i 67,1% ženskog pola, koji su se izjasnili o
 potrebi internet u toku studiranja i  na skali od 1 “malo” do 5 “mnogo”, ocenili da je prosečna potreba za internetom tokom studiranja iznosila 4,4. Veći nivo procedualnog
 znanja je bio povezan sa većom potrebom za internetom tokom studiranja (r=0,289. p=0,008). Pozitivna korelacija potrebe internet je zabeležena i sa svim subkomponentama  
“Regulacije kognicije”, za planiranje (r=0,249; p=0,024), strategiju upravljanja informacijama (r=0,396; p<0,001), praćenje učenja i razumevanja (r=0,316; p=0,004),
 strategiju za ispravljanje grešaka (r=0,275; p=0,012) i evaluaciju (r=0,294; p=0,007). Najača povezanost potrebe internet tokom studiranja je bila sa strategijom upravljanja
 informacijama. Veća potreba korišćenja interneta među studentima  je uticala da uspore sa radom kada naiđu na važne informacije (4,4), fokusiraju se na nove informacije
 (4,3), teže da ih preformulišu svojim rečima (4,4) i povezuju ih sa onim što već znaju (4,4).
 Zaključak: Korišćenje internet tokom studiranja utiče na veći stepen metakognicije i svesnosti studenata da prepoznaju nove i važne informacije. Pomaže im kako da usvoje
 nove informacije, da se na njih fokusiraju, da ih preformulisu i kako da ih povežu sa već postojećim znanjem.
 Ključne reči: Metakognicija, upotreba internet, studenti medicine, MAI

Anatomical variants of circle of Willis

Introduction: The circle of Willis is the major source of collateral blood flow between the carotid and vertebrobasilar system. Its potential depends on the presence and size of arteries that vary greatly among normal individuals and therefore their adequate observation by a radiologist is necessary. Aim: Determine the type of the circle of Willis and their frequency. Determine the type, frequency and localization of anatomical variants of arteries, as well as their average diameter. Compare these variables according to the age and gender of the examinees. Material and methods: A retrospective study was performed at the Center for Radiology of the Clinical Center Nis during 2017. All subjects underwent CT or MR angiography according to a standard endocranial protocol. The anterior and posterior parts of the circle were specially observed, with an emphasis on the presence or absence of anatomical variants of the arteries, with the measurement of their diameter. The obtained data were classified into variants of the front or rear part of the ring as well as the type of ring according to integrity. The frequency of these variables and their comparison by sex and age were measured. Results: The research included 92 examinees. According to the configuration of the Willis arterial ring, the adult type was the most often represented (71.7%). The most common type in terms of integrity was partially complete. The most common anatomical variants obtained in our work was aplasia of AcoA (27.2%) and aplasia of one or both PCoA (21%). PcoA hypoplasia was occured in women with a frequency of 13.5% while in men it was not present. Conclusion: Adequate understanding of the morphology of the circle of Willis by radiological methods is a good guide for neurosurgical and radiological intervention procedures. In this way, potentially significant neurological complications and the risk of morbidity and mortality could be reduced.

CLINICAL-MORPHOLOGICAL CHARACTERISTICS OF PATHOLOGICAL CHANGES IN THE PROSTATE

The most significant prostate diseases (PD) are benign prostatic hyperplasia (BPH), prostatic intraepithelial neoplasia
(PIN) and prostate cancer (PC). Generally, all PD are rare before the age of 50 with growing number of patients, primarily
with BHP, with each next decade, but about decade later the highest number of PIN and PC began to report. The aim of this
paper is to examine some of clinical, biochemical and histopathological characteristics of BPH, PIN and PC. Our sample
consisted of 169 men. Statisticaly the most common PD was BPH-77.5%, and the rarest PIN-8.3% (p<0.001). The average age of patients was 70.6±7.5 years (51-89) with no significant differences between diagnosis (p=0.415). PIN and PC are more often found in people from urban areas (p=0.004). In the central prostate area BPH is significantly higher in 88.5% (p<0.001). Peripheral parts are significantly more common places of PIN and PC (p<0.001). Median serum PSA values is statistically highest in PC-87.2 ng/ml (12.7-372.5), (p<0,001), especially those with predominantly peripheral parts localization. Gleason score is an important prognostic factor, with average value at PC is 7.32±1.4 (5-10), with a significantly higher values for diffuse PC. BPH is the most common, and PIN rarest PD. All diseases have occurred in people older than 50 years. Usually, BPH is in central and PIN and PC in peripheral prostate parts. PSA values were highest at PC, which is a prove of its importance in malignancy early detection.

SERUM VITAMIN D ANALYSIS IN ACUTE VIRAL BRONCHIOLITIS

Bronchiolitis is an acute viral disease of lower respitatory pathways in children under 2 years of age. It is manifested by coughing, whistling and refusing food intake. The most common cause of bronchiolitis is a respiratory syncytial virus. Vitamin D is a steroid hormone which is synthesized in the skin after sun exposure or food intake. With discovery of Vitamin D receptors and hydroxylated enzymes in immune cells, a potential role for Vitamin D in maintaining immune homeostasis was seen. It has been established that Vitamin D induces a change of the antimicrobial polypeptide, cathelicidin, which has both antibacterial and antiviral roles.
