- A lack of knowledge of naturally occurring pathogens is limiting our ability to use the Antarctic to study the impact human-mediated introduction of infectious microorganisms have on this relatively uncontaminated environment. As no large-scale coordinated effort to remedy this lack of knowledge has taken place, we rely on smaller targeted efforts to both study present microorganisms and monitor the environment for introductions. In one such effort, we isolated Campylobacter species from fecal samples collected from wild birds in the Antarctic Peninsula and the sub-Antarctic island of South Georgia. Indeed, in South Georgia, we found Campylobacter lari and the closely related Campylobacter peloridis, but also distantly related human-associated multilocus sequence types of Campylobacter jejuni. In contrast, in the Antarctic Peninsula, we found C. tart and two closely related species, Campylobacter subantarcticus and Campylobacter volucris, but no signs of human introduction. In fact, our finding of human-associated sequence types of C. jejuni in South Georgia, but not in the Antarctic Peninsula, suggests that efforts to limit the spread of infectious microorganisms to the Antarctic have so far been successful in preventing the introduction of C. jejuni. However, we do not know how it came to South Georgia and whether the same mode of introduction could spread it from there to the Antarctic Peninsula.

Konstnärligt arbete (övrigt vetenskapligt/konstnärligt)abstract
- This Swedish violinist and marimba a duo is confidently carving a genre of their own. Granmo-Berg’s years of experience and passion shines through every moment of this High-End live recording. With only two microphones, the sound is natural, dynamic and lively. The music is an eclectic mixture of Classical, Percussion and Latin composed by Bach, Vivaldi and Béla Bartók. It also includes works by well known Swedish composers, and songs written by themselves. Recorded by renowned musician and producer Peter Axelsson at Marten Recordings state-of-the-art studio.

Sinnenas musik : En exkursion i sex satser
- 2023
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- Vad händer när musik möter människans olika sinnen? Hur påverkas vi av musiken vi hör, och vad kan vi med sinnenas hjälp lära oss? Hur låter champagne, hur doftar Vivaldi och vad kan klanger ge för aromatiska associationer? ”Sinnenas musik” är en utforskning av musikens betydelse för våra sinnen och hur våra sinnen korsbefruktar varandra. Att musik har betydelse för både kropp och själ har nog de flesta personlig erfarenhet av. Inte minst hjärnans olika funktioner påverkas av tonkonst, som motivation, uppmärksamhet, känslor, minne och språkförmåga. Ny forskning visar också att kultur i olika former kan vara skyddande mot bland annat Alzheimers sjukdom. Så vare sig du lever i allegrissimo eller i ett lugnare andante, i dur eller moll, gillar ensemblespel eller föredrar solouppträdanden, påverkas alla dina sinnen av musik kanske också på ett sätt som du inte är helt medveten om. Boken har tillkommit efter en seminarieserie på Jonsereds herrgård vid Göteborgs universitet. Redaktörer är Anna Falkenland och Lena Ulrika Rudeke. Textförfattaren Eva Lundgren är redaktör och journalist. Förord av Catharina Dyrssen, professor emerita i arkitektur och designmetodik. Länk till musik med Duo Granmo-Berg – Tobias Granmo, violinist och lektor i kammarmusik, och Daniel Berg, slagverkare, kompositör och professor i musikalisk gestaltning. Boken avslutas med en ackompanjerande bildsvit för fortsatt utforskande av sinnenas korsbefruktning.

Sudden Cardiac Death Prediction in Arrhythmogenic Right Ventricular Cardiomyopathy : A Multinational Collaboration
- 2021

Tidskriftsartikel (refereegranskat)abstract
- Background: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is associated with ventricular arrhythmias (VA) and sudden cardiac death (SCD). A model was recently developed to predict incident sustained VA in patients with ARVC. However, since this outcome may overestimate the risk for SCD, we aimed to specifically predict life-threatening VA (LTVA) as a closer surrogate for SCD. Methods: We assembled a retrospective cohort of definite ARVC cases from 15 centers in North America and Europe. Association of 8 prespecified clinical predictors with LTVA (SCD, aborted SCD, sustained, or implantable cardioverter-defibrillator treated ventricular tachycardia >250 beats per minute) in follow-up was assessed by Cox regression with backward selection. Candidate variables included age, sex, prior sustained VA (≥30s, hemodynamically unstable, or implantable cardioverter-defibrillator treated ventricular tachycardia; or aborted SCD), syncope, 24-hour premature ventricular complexes count, the number of anterior and inferior leads with T-wave inversion, left and right ventricular ejection fraction. The resulting model was internally validated using bootstrapping. Results: A total of 864 patients with definite ARVC (40±16 years; 53% male) were included. Over 5.75 years (interquartile range, 2.77-10.58) of follow-up, 93 (10.8%) patients experienced LTVA including 15 with SCD/aborted SCD (1.7%). Of the 8 prespecified clinical predictors, only 4 (younger age, male sex, premature ventricular complex count, and number of leads with T-wave inversion) were associated with LTVA. Notably, prior sustained VA did not predict subsequent LTVA (P=0.850). A model including only these 4 predictors had an optimism-corrected C-index of 0.74 (95% CI, 0.69-0.80) and calibration slope of 0.95 (95% CI, 0.94-0.98) indicating minimal over-optimism. Conclusions: LTVA events in patients with ARVC can be predicted by a novel simple prediction model using only 4 clinical predictors. Prior sustained VA and the extent of functional heart disease are not associated with subsequent LTVA events.
