Teleostei, Scophthalmidae: four-spot megrim spotted in Norwegian waters

The flatfish four-spot megrim (Lepidorhombus boscii) was registered in Norwegian waters, both in trawl catches and video observations. The records represent a considerable northward extension of the species. Specimens of up to 49 cm were measured, representing also a new maximum size for this species. The number of registrations has increased within the last years, indicating that the species got more common in this area

Marinbiologisk mangfold i Andfjorden marine verneområde

Andfjorden marine verneområde er et stort område som strekker seg fra fjord til hav. Området har en variert topografi som gir levested for en stor variasjon av marine arter. Her finnes rekefelt og gyteområder for torsk, kveite, uer og rognkjeks. En rekke naturtyper er kartlagt i området slik som skjellsand, tareskog og ruglbunn. Sårbare naturtyper som korallrev, bambuskorallskog, hardbunnskorallskog, svampskog og sjøfjærbunn er observert gjennom Mareano undersøkelser og av fiskere i Andfjorden. For første gang er biotop-modellering brukt som redskap for å predikere forekomsten av hardbunnskoraller, bløtbunnskoraller og svampskog i et marint verneområde på norskekysten.publishedVersio

Lebetus scorpioides and Buenia jeffreysii (Teleostei: Gobiidae) found north of the Arctic Circle

Two gobiid species, Lebetus scorpioides and Buenia jeffreysii, were recorded in northern Norway, for the first time north of the Arctic Circle. While both species were found on the continental shelf west of the Lofoten islands, one of them, L. scorpioides, was found north of 70°N off western Finnmark. The records represent a considerable northward extension of the distribution of these species. Being well within the size of reproductive individuals, the specimens appear to belong to resident populations most probably missed by earlier samplings

Coeliac disease in the Trøndelag Health Study (HUNT), Norway, a population-based cohort of coeliac disease patients

Purpose: Coeliac disease (CD) is a common disorder and affects about 1% of the population worldwide. CD in the Trøndelag Health Study (HUNT) is a population-based cohort study which was established to provide new knowledge about CD that can improve the diagnostics and management, prevent the onset or progression and expand the knowledge about the role of genetics of the disease.Participants: The cohort is based on the fourth wave of the population-based HUNT study (HUNT4), Norway, performed during 2017–2019, also including linkage to hospital records and the Norwegian Patient Registry (NPR). A total of 54 541 HUNT4 participants with available sera were screened for CD by serology. All seropositive participants were invited to a clinical assessment, including endoscopy with duodenal biopsies, during 2019–2023.Findings to date: A total of 1107 HUNT4 participants (2%) were seropositive for CD and 1048 were eligible for clinical assessment, including biopsy. Of these, 724 participants attended the clinical assessment and 482 were identified with CD. In addition, 371 participants with CD were identified through the hospital records and NPR. In total, 853 participants in HUNT4 with biopsy-verified CD diagnosis were identified.Future plans: All participants in the study will be invited to a follow-up assessment after at least 1 year, including repeated standard serological testing, endoscopy and tissue sampling. The collected data and material will be used to establish the true population-based prevalence of CD. The consequences of CD, including symptoms, deficiencies and comorbidity, will be investigated and possible triggers and predictors, will be studied. With access to serum samples from the previous HUNT surveys in HUNT Biobank, serological signs of CD in prediagnostic samples of seropositive individuals will be used. Genetic studies will identify new CD markers, assess genotype–phenotype links and explore gene–environment correlations
