1. Izolacija in priprava celičnih linij ledvic z namenom razvoja novih in vitro modelov nefrotoksičnostiTadej Petreski, 2025, doctoral dissertation Abstract: Ledvice so ključne za številne homeostatske mehanizme in so odgovorne za velik delež izločanja snovi iz telesa, zaradi česar so posebej dovzetne za delovanje nefrotoksičnih spojin. Med različnimi vrstami ledvičnih celic so proksimalne tubulne epitelijske celice (PTEC), ki sodelujejo pri tubularni sekreciji snovi, najbolj izpostavljene in zato ključnega pomena za razumevanje nefrotoksičnosti ter interakcij med zdravili v predkliničnih raziskavah. Omejena razpoložljivost in funkcionalna variabilnost komercialno dostopnih PTEC predstavlja ozko grlo pri teh raziskavah, zato je razvoj zanesljivih protokolov za njihovo izolacijo ključna za nadaljnji razvoj področja.
V tej disertaciji sta predstavljena dva optimizirana protokola za izolacijo primarnih PTEC iz rutinskih biopsij ledvičnega tkiva, pridobljenih od 13 bolnikov. Rezultat tega sta dve celični liniji, poimenovani MFUM-RPTEC-1 in MFUM-RPTEC-2. Obe celični liniji izražata za PTEC celice ključne označevalce, vključno s SGLT2, MRP4, OAT1, OAT3, OCT2, P-gp, MATE1, N-kadherinom, ZO-1 in CK-18. Ob gojenju na Transwell ploščah so celice pokazale ustrezno polarizacijo, saj so bili transportni proteini lokalizirani na predvideni (apikalni ali bazolateralni) strani, kar je bilo potrjeno tudi s konfokalno mikroskopijo.
Potencial ustvarjenih celičnih linij za uporabo v predkliničnih raziskavah smo preverjali s pripravo enostavnega in vitro modela za raziskovanje nefrotoksičnosti in interakcij med izbranimi zdravili. Celice so ohranile svojo viabilnost tudi po izpostavitvi nefrotoksičnim spojinam, kot so ciklosporin, omeprazol in njuni kombinaciji, kar dokazuje potencial celičnih linij za nadaljnji razvoj orodij in vzpostavitev raziskav na področju farmakologije ledvic.

2. Clinical reasoning needs to be explicitly addressed in health professions curricula : recommendations from a European consortiumIoannis Parodis, Lina Andersson, Steven J. Durning, Inga Hege, Jure Knez, Andrzej Kononowicz, Marie Lidskog, Tadej Petreski, Magdalena Szopa, Samuel Edelbring, 2021, original scientific article Abstract: Clinical reasoning entails the application of knowledge and skills to collect and integrate information, typically with the goal of arriving at a diagnosis and management plan based on the patient’s unique circumstances and preferences. Evidence-informed, structured, and explicit teaching and assessment of clinical reasoning in educational programs of medical and other health professions remain unmet needs. We herein summarize recommendations for clinical reasoning learning objectives (LOs), as derived from a consensus approach among European and US researchers and health professions educators. A four-step consensus approach was followed: (1) identification of a convenience sample of the most relevant and applied national LO catalogues for health professions educational programs (N = 9) from European and US countries, (2) extraction of LOs related to clinical reasoning and translation into English, (3) mapping of LOs into predefined categories developed within the Erasmus+ Developing, implementing, and disseminating an adaptive clinical reasoning curriculum for healthcare students and educators (DID-ACT) consortium, and (4) synthesis of analysis findings into recommendations for how LOs related to clinical reasoning could be presented and incorporated in LO catalogues, upon consensus. Three distinct recommendations were formulated: (1) make clinical reasoning explicit, (2) emphasize interprofessional and collaboration aspects of clinical reasoning, and (3) include aspects of teaching and assessment of clinical reasoning. In addition, the consortium understood that implementation of bilingual catalogues with English as a common language might contribute to lower heterogeneity regarding amount, structure, and level of granularity of clinical reasoning LOs across countries. These recommendations will hopefully motivate and guide initiatives towards the implementation of LOs related to clinical reasoning in existing and future LO catalogues.
