1. Risk factors for systemic reactions in typical cold urticaria : results from the COLD-CE studyMitja Košnik, Dejan Dinevski, Simon Francis Thomsen, Daria Fomina, Elena Borzova, Kanokvalai Kulthanan, Raisa Meshkova, Dalia Melina Ahsan, Mona Al-Ahmad, Jovan Miljković, Dorothea Terhorst, 2022, izvirni znanstveni članek Opis: Background: Cold urticaria (ColdU), i.e. the occurrence of wheals or angioedema in response to cold exposure, is classified into typical and atypical forms. The diagnosis of typical ColdU relies on whealing in response to local cold stimulation testing (CST). It can also manifest with cold-induced anaphylaxis (ColdA). We aimed to determine risk factors for ColdA in typical ColdU.
Methods: An international, cross-sectional study COLD-CE was carried out at 32 urticaria centers of reference and excellence (UCAREs). Detailed history was taken and CST with an ice cube and/or TempTest® performed. ColdA was defined as an acute cold-induced involvement of the skin and/or visible mucosal tissue and at least one of: cardiovascular manifestations, difficulty breathing, or gastrointestinal symptoms.
Results: Of 551 ColdU patients, 75% (n=412) had a positive CST and ColdA occurred in 37% (n=151) of the latter. Cold-induced generalized wheals, angioedema, acral swelling, oropharyngeal/laryngeal symptoms, and itch of earlobes were identified as signs/symptoms of severe disease. ColdA was most commonly provoked by complete cold water immersion and ColdA caused by cold air was more common in countries with a warmer climate. Ten percent (n=40) of typical ColdU patients had a concomitant chronic spontaneous urticaria (CSU). They had a lower frequency of ColdA than those without CSU (4% vs 39%, p=0.003). We identified the following risk factors for cardiovascular manifestations: previous systemic reaction to a Hymenoptera sting, angioedema, oropharyngeal/laryngeal symptoms, and itchy earlobes.
Conclusion: ColdA is common in typical ColdU. High-risk patients require education about their condition and how to use an adrenaline autoinjector.

2. Biometrija, spolna dvoličnost in razmnoževalna biologija izbranih vrst rakovic (crustacea: decapoda) v severnem jadranuMona Rezaei, 2020, doktorska disertacija Opis: Povzetek
Raziskovana je bila distribucija in struktura populacije 4 vrst rakovic (Decapoda: Crustacea), Medorippe lanata, Goneplax rhomboides, Liocarcinus depurator in Liocarcinus vernalis, glede morebitnih učinkov na ribištvo in uporabo vlečnih mrež na njihovo populacijo. Raziskava je bila narejena v severnem Jadranu.
Kot del ribiške odprave, je bilo decembra 2013 v vodah severnega Jadrana ulovljenih skupaj 1100 primerkov, vseh 4 vrst. Rakovice so bile zbrane iz 32 vzorčnih postaj. Globina voda se je gibala med 10,6 m in 84 m. Izvedene so bile biometrične meritve ter prešteto je bilo število jajčec. (L. depurator in L. vernalis).
Razmerje samic in samcev (L. depurator, L. vernalis, M. lanata in G. rhomboides) je bilo sledeče - 1:1.5, 1:2, 1:0.8 in 1:57. Med vrstama L. depurator in L. vernalis ni bilo pomembnejših razlik v številu jajčec. Nobene pomembne povezave ni bilo ugotovljene med zunanjim oklepom (širina / dolžina) in številom jajčec teh rakovic. G. rhomboides ima očitno večji Fultonov pogojni indeks kot ostale vrste. Povezava med globino vode in merjenimi biometričnimi parametri so dale šibke, vendar pomembne rezultate, v glavnem pri samcih L. Vernalis. Rakovic obeh spolov je bilo obilo na vseh proučevanih globinah in ni bilo pomembnejše povezave med globino morja in številom rakovic. Samo v primeru (M. Lanata) je bila razporeditev le teh bolj izrazita na globinah manjših od 50 metrov, ne glede na spol. Samci L.vernalis so bili precej večji od samic, kar kaže na velikost spolne dvoličnosti. Ta velikost dvoličnosti je bila opažena pri M. lanata na stopnji zunanjega oklepa, brez večje razlike v mokri teži. Vseeno pri tej vrsti so bile samice večje, pri merjenju zunanjega oklepa, kot samci.
