- Introduction: The incidence of hyperthyroidism has been reported in various countries to be 23-93/100000 inhabitants per year. This extended study has evaluated the incidence for similar to 40% of the Swedish population of 9 million inhabitants. Sweden is considered to be iodine sufficient country. Methods:All patients including children, who were newly diagnosed with overt hyperthyroidism in the years 2003-2005, were prospectively registered in a multicenter study. The inclusion criteria are as follows:clinical symptoms and/or signs of hyperthyroidism with plasma TSH concentration below 0.2 mIE/l and increased plasma levels of free/total triiodothyronine and/or free/total thyroxine. Patients with relapse of hyperthyroidism or thyroiditis were not included. The diagnosis of Graves' disease (GD), toxic multinodular goiter (TMNG) and solitary toxic adenoma (STA), smoking, initial treatment, occurrence of thyroid-associated eye symptoms/signs, and demographic data were registered. Results:A total of 2916 patients were diagnosed with de novo hyperthyroidism showing the total incidence of 27.6/100 000 inhabitants per year. The incidence of GD was 21.0/100 000 and toxic nodular goiter (TNG=STA+TMNG) occurred in 692 patients, corresponding to an annual incidence of 6.5/100 000. The incidence was higher in women compared with men (4.2:1). Seventy-five percent of the patients were diagnosed with GD, in whom thyroid-associated eye symptoms/signs occurred during diagnosis in every fifth patient. Geographical differences were observed. Conclusion:The incidence of hyperthyroidism in Sweden is in a lower range compared with international reports. Seventy-five percent of patients with hyperthyroidism had GD and 20% of them had thyroid-associated eye symptoms/signs during diagnosis. The observed geographical differences require further studies.

- The herpes simplex virus type 1 (HSV-1) glycoprotein gC-1 is engaged both in viral attachment and viral immune evasion mechanisms in the infected host. Besides several N-linked glycans, gC-1 contains numerous O-linked glycans, mainly localized in two pronase-resistant clusters in the N-terminal domain of gC-1. In the present study we construct and characterize one gC-1 mutant virus, in which two basic amino acids (114K and 117R) in a putative O-glycosylation sequon were changed to alanine. We found that this modification did not modify the N-linked glycosylation but increased the content of O-linked glycans considerably. Analysis of the O-glycosylation capacity of wild-type and mutant gC-1 was performed by in vitro glycosylation assays with synthetic peptides derived from the mutant region predicted to present new O-glycosylation sites. Thus the mutant peptide region served as a better substrate for polypeptide GalNAc-transferase 2 than the wild-type peptide, resulting in increased rate and number of O-glycan attachment sites. The predicted increase in O-linked glycosylation resulted in two modifications of the biological properties of mutant virus-that is, an impaired binding to cells expressing chondroitin sulfate but not heparan sulfate on the cell surface and a significantly reduced plaque size in cultured cells. The results suggested that basic amino acids present within O-glycosylation signals may down-regulate the amount of O-linked glycans attached to a protein and that substitution of such amino acid residues may have functional consequences for a viral glycoprotein involving virus attachment to permissive cells as well as viral cell-to-cell spread.

Rapport (populärvet., debatt m.m.)abstract
- Förvaltningsrapporten fokuserar på Snomed CT, eftersom det redan i dag finns rutiner för förvaltningar av termbanken och nationella hälsorelaterade klassifikationer. Ett särskilt utvecklingsarbete kommer att krävas för dessa delar.Rapporten tar upp syfte och mål med förvaltningen. Utöver det redogör rapporten för vilka konkreta ansvarsområden som ingår i förvaltningen av Snomed CT. Målet för förvaltningen är att Socialstyrelsen regelbundet ska kunna tillhandahålla en kontrollerad och uppdaterad release av Snomed CT. Det skulle möjliggöra användning inom vård och omsorg. Rapporten tar även upp behovet av kompetens, utbildning och finansiella resurser.

Home Blood Pressure in Health and Disease
- 2024

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Hypertension is the most common preventable cause of premature all-cause mortality, primarily from cardiovascular disease (CVD). Individuals with dysglycemia, including prediabetes and diabetes, are at increased risk. Licorice intake raises blood pressure (BP) through the effects of glycyrrhizic acid (GA), but the true limit of safe intake is uncertain. Home BP has several benefits over BP measured at a clinic, including a higher predictive value for CVD. By combining office and home BP, it is possible to diagnose masked hypertension (MH), in which home but not office BP is elevated, and white coat hypertension (WCH), in which office but not home BP is elevated. The aim of this thesis was to advance our knowledge on home BP in relation to dysglycemia, markers of CVD, and licorice intake. The first 3 papers used data from the Linköping cohort of the prospective Swedish CArdioPulmonary bioImage Study (SCAPIS). Study IV was a randomized controlled cross-over study. Data was obtained from questionnaires, blood samples and office and home BP measurements. In studies I-III, pulse wave velocity (PWV), coronary artery calcium score (CACS), and carotid artery plaques as markers of CVD were also included. In Study I, we examined 5025 men and women aged 50-64 years old for the relation between dysglycemia and home BP. Both the systolic office and home BP measurements were positively as-sociated with dysglycemia. Participants with dysglycemia vs normoglycemia more often had MH. The findings were in line with previous research and strengthened the association between dysglycemia and MH. In Study II, we examined the associations between MH and markers of CVD in 4122 individuals without BP-lowering treatment. Of participants, 4.2% had MH, and these were more often men and had higher BMI than those with normotension. Participants with MH also had higher odds for CACS ≥100, an as-sociation which has previously been suggested as a trend.In Study III, we examined the relation between soluble P-se-lectin (sP-selectin) as a measure of thrombotic activity, plasma high-sensitivity C-reactive protein (hsCRP) as a measure of inflammation, and home BP in 4548 participants. Both markers were higher in each hypertension phenotype compared with sustained normotension. The quartile of participants with the highest sP-se-lectin values had higher odds for CACS ≥100 and carotid artery plaques. The association between sP-selectin and sustained hyper-tension was novel and not affected by adjustments for hsCRP. In Study IV, 28 healthy participants aged 18-30 years old were evaluated for the effects of a daily intake of licorice containing 100 mg of GA compared with a control product for 2 weeks. During the licorice intake period, the systolic home BP increased with 3.1 mmHg, and the suppression of serum aldosterone and plasma renin levels indicated that this was due to the licorice intake. In conclusion, this thesis further strengthens the idea that both home and office BP measurements have values beyond that of the other, and that home BP may be most valuable in individuals with dysglycemia and obesity, and in men. Finally, licorice may be more potent than previously known, suggesting the need for increased awareness.

Konferensbidrag (refereegranskat)abstract
- The United Nations identifies the food crisis as one of the primary overarching challenges facing the international community. Different stakeholders in the food system have widely different perspectives and interests, and challenging structural issues, such as the power differentials among them, remain largely unexamined. These challenges make rational discourse among food system actors from different disciplines, sectors and levels difficult. These challenges can often prevent them from working together effectively to find innovative ways to respond to food security challenges. This means that finding solutions to intractable and stuck issues, such as the food crisis often stall, not at implementation, but at the point of problem identification. Food system sustainability means very different things to different food system actors. These differences in no way undermine or discount the work carried out by these players. However, making these differences explicit is an essential activity that would serve to deepen theoretical and normative project outcomes. Would the impact and reach of different food projects differ if these differences were made explicit? The purpose of this initial part of a wider food system research project is not to search for difference or divergence, with the aim of critique, but rather to argue that by making these differences explicit, the overall food system project engagement will be made more robust, more inclusive and more encompassing. This paper starts with some discussion on the different food system perspectives, across scales, regions and sectors but focuses primarily on the design of processes used to understand these divergent and at times contradictory views of what a sustainable food system may be. This paper draws on ongoing work within the Mistra Urban Futures project, using the food system projects in cities as diverse as Cape Town, Manchester, Gothenburg and Kisumu as sites for this enquiry.

Infectivity of exhaled SARS-CoV-2 aerosols is sufficient to transmit covid-19 within minutes

Tidskriftsartikel (refereegranskat)abstract
- Exhaled SARS-CoV-2-containing aerosols contributed significantly to the rapid and vast spread of covid-19. However, quantitative experimental data on the infectivity of such aerosols is missing. Here, we quantified emission rates of infectious viruses in exhaled aerosol from individuals within their first days after symptom onset from covid-19. Six aerosol samples from three individuals were culturable, of which five were successfully quantified using TCID50. The source strength of the three individuals was highest during singing, when they exhaled 4, 36, or 127 TCID50/s, respectively. Calculations with an indoor air transmission model showed that if an infected individual with this emission rate entered a room, a susceptible person would inhale an infectious dose within 6 to 37 min in a room with normal ventilation. Thus, our data show that exhaled aerosols from a single person can transmit covid-19 to others within minutes at normal indoor conditions.
