- OBJECTIVES: To explore treatment outcomes preferred by patients with early rheumatoid arthritis (RA) and how these change throughout the early disease stage across three European countries.METHODS: A longitudinal, qualitative, multicentre study was conducted in Belgium, the Netherlands and Sweden. 80 patients with early RA were individually interviewed 3-9 months after treatment initiation and 51 of them participated again in either a focus group or an individual interview 12-21 months after treatment initiation. Data were first analysed by country, following the Qualitative Analysis Guide of Leuven (QUAGOL). Thereafter, a meta-synthesis, inspired by the principles of meta-ethnography and the QUAGOL, was performed, involving the local research teams.RESULTS: The meta-synthesis revealed 11 subthemes from which four main themes were identified: disease control, physical performance, self-accomplishment and well-being. 'A normal life despite RA' was an overarching patient-preferred outcome across countries. Belgian, Dutch and Swedish patients showed many similarities in terms of which outcomes they preferred throughout the early stage of RA. Some outcome preferences (eg, relief of fatigue and no side effects) developed differently over time across countries.CONCLUSIONS: This study on patient-preferred outcomes in early RA revealed that patients essentially want to live a normal life despite RA. Our findings help to understand what really matters to patients and provide specific insights into the early stage of RA, which should be addressed by clinicians of different disciplines from the start of treatment onwards. © Author(s) (or their employer(s)) 2020.

- To summarize all available data on pregnancy outcome of acromegaly patients exposed to the growth hormone receptor antagonist pegvisomant (PEGV) during pregnancy as present in the Pfizer's Global Safety Database. Pfizer's Global Safety Database contains adverse event data obtained from the following sources: spontaneous reports, health authorities, Pfizer-sponsored post-marketing surveillance program (ACROSTUDY), customer engagement programs, and clinical studies, reported regardless of outcome. The safety database was searched up to 10th March 2014. From the 35 pregnancy cases, 27 involved maternal [mean age (range) 33.3 years (23-41) and 8 paternal (33.7 years (32-38)] PEGV exposure. Two female patients were reported with two pregnancy cases each. Fetal outcome was normal in 14 (4 paternal) of the 18 reported as live birth, while 4 cases (1 paternal) did not specify the birth outcome. At conception, PEGV mean dose (range) was 15.3 mg/d (4.3-30). In 3 cases of maternal exposure of the 18 cases reporting live birth, PEGV was continued throughout the pregnancy in a dose of 12.1 mg/d (10-15). In 5 cases (all maternal) an elective termination of the pregnancy was performed with no reported fetal abnormalities, 2 cases (maternal) reported a non-PEGV-related spontaneous abortion and in 1 maternal case an ectopic pregnancy occurred. In 9 cases (3 paternal), the fetal outcome was not reported. Three women reported gestational diabetes; one woman continued PEGV treatment during pregnancy. Although the number of reported pregnancies with exposure to PEGV is very small, the presented data reflect the largest series of data available to date and do not suggest adverse consequences of PEGV on pregnancy outcome. Nevertheless, it should be stressed that PEGV should not be used during pregnancy unless absolutely necessary.

Forskningsöversikt (refereegranskat)abstract
- Thirty-seven laboratories from 25 countries present the development of an inter-laboratory testing scheme for the analysis of seven illicit drug residues in standard solutions, tap- and wastewater. Almost 10 000 concentration values were evaluated: triplicates of up to five samples and 26 laboratories per year. The setup was substantially improved with experiences gained across the six repetitions (e.g. matrix type, sample conditions, spiking levels). From this, (pre-)analytical issues (e.g. pH adjustment, filtration) were revealed for specific analytes which resulted in formulation of best-practice protocols for inter-laboratory setup and analytical procedures. The results illustrate the effectiveness of the interlaboratory setup to assess laboratory performance in the framework of wastewater-based epidemiology. The exercise proved that measurements of laboratories were of high quality (>80% satisfactory results for six out of seven analytes) and that analytical follow-up is important to assist laboratories in improving robustness of wastewater-based epidemiology results.

- Global dust storms on Mars are rare1,2 but can affect the Martian atmosphere for several months. They can cause changes in atmospheric dynamics and inflation of the atmosphere3, primarily owing to solar heating of the dust3. In turn, changes in atmospheric dynamics can affect the distribution of atmospheric water vapour, with potential implications for the atmospheric photochemistry and climate on Mars4. Recent observations of the water vapour abundance in the Martian atmosphere during dust storm conditions revealed a high-altitude increase in atmospheric water vapour that was more pronounced at high northern latitudes5,6, as well as a decrease in the water column at low latitudes7,8. Here we present concurrent, high-resolution measurements of dust, water and semiheavy water (HDO) at the onset of a global dust storm, obtained by the NOMAD and ACS instruments onboard the ExoMars Trace Gas Orbiter. We report the vertical distribution of the HDO/H2O ratio (D/H) from the planetary boundary layer up to an altitude of 80 kilometres. Our findings suggest that before the onset of the dust storm, HDO abundances were reduced to levels below detectability at altitudes above 40 kilometres. This decrease in HDO coincided with the presence of water-ice clouds. During the storm, an increase in the abundance of H2O and HDO was observed at altitudes between 40 and 80 kilometres. We propose that these increased abundances may be the result of warmer temperatures during the dust storm causing stronger atmospheric circulation and preventing ice cloud formation, which may confine water vapour to lower altitudes through gravitational fall and subsequent sublimation of ice crystals3. The observed changes in H2O and HDO abundance occurred within a few days during the development of the dust storm, suggesting a fast impact of dust storms on the Martian atmosphere.

- Purpose: The role of antigen(s) in shaping the T-cell repertoire in chronic lymphocytic leukemia, although relevant for understanding malignant cell interactions with cognate T cells, is largely unexplored. Experimental Design: Here we profiled the T-cell receptor beta chain gene repertoire in 58 chronic lymphocytic leukemia patients, focusing on cases assigned to well-characterized subsets with stereotyped clonotypic B-cell receptor immunoglobulins, therefore those cases most evidently selected by antigen (subsets #1, #2, and #4). Results: Remarkable repertoire skewing and oligoclonality were observed, and differences between subsets were noted regarding both T-cell receptor b chain gene usage and the extent of clonality, with subset #2 being the least oligoclonal. Longitudinal analysis of subset #4 cases revealed that although the repertoire may fluctuate over time, certain clonotypes persist, thus alluding to persistent antigenic stimulation. Shared ("stereotyped") clonotypes were found between different patients, reflecting selection by common antigenic elements. Cross-comparison of our dataset with public databases showed that some T-cell clonotypes may have expanded secondary to common viral infections; however, the majority of clonotypes proved to be disease-specific. Conclusions: Overall, the T-cell receptor b chain repertoire in chronic lymphocytic leukemia is likely shaped by antigen selection and the implicated antigenic elements may concern epitopes that also select the malignant B-cell progenitors or, more intriguingly, chronic lymphocytic leukemia-derived epitopes.

IgG-Switched CLL Has a Distinct Immunogenetic Signature from the Common MD Variant : Ontogenetic Implications

- PURPOSE:IgG-switched chronic lymphocytic leukemia (G-CLL) is a rare variant of CLL, whose origin and ontogenetic relationship to the common IgM/IgD (MD-CLL) variant remains undefined. Here we sought for clues regarding the ontogeny of G-CLL versus MD-CLL by profiling the relevant IG gene repertoires.EXPERIMENTAL DESIGN:Using purpose-built bioinformatics methods, we performed detailed immunogenetic profiling of a multinational CLL cohort comprising 1256 cases, of which 1087 and 169 expressed IG mu/delta and gamma heavy chains, respectively.RESULTS:G-CLL has a highly skewed IG gene repertoire that is distinct from MD-CLL, especially in terms of: (i) overuse of the IGHV4-34 and IGHV4-39 genes; and, (ii) differential somatic hypermutation (SHM) load. Repertoire differences held also when comparing subgroups with similar SHM status and were mainly attributed to the exclusive representation in G-CLL of two major subsets with quasi-identical (stereotyped) B-cell receptors. These subsets, namely #4 (IGHV4-34/IGKV2-30) and #8 (IGHV4-39/IGKV1(D)-39), were found to display sharply contrasting SHM and clinical behavior.CONCLUSIONS:G-CLL exhibits an overall distinct immunogenetic signature from MD-CLL, prompting speculations about distinct ontogenetic derivation and/or immune triggering. The reasons underlying the differential regulation of SHM among G-CLL cases remain to be elucidated.

Tidskriftsartikel (refereegranskat)abstract
- Recent prospective studies have shown that dysregulation of the immune system may precede the development of B‐cell lymphomas (BCL) in immunocompetent individuals. However, to date, the studies were restricted to a few immune markers, which were considered separately. Using a nested case–control study within two European prospective cohorts, we measured plasma levels of 28 immune markers in samples collected a median of 6 years before diagnosis (range 2.01–15.97) in 268 incident cases of BCL (including multiple myeloma [MM]) and matched controls. Linear mixed models and partial least square analyses were used to analyze the association between levels of immune marker and the incidence of BCL and its main histological subtypes and to investigate potential biomarkers predictive of the time to diagnosis. Linear mixed model analyses identified associations linking lower levels of fibroblast growth factor‐2 (FGF‐2 p = 7.2 × 10−4) and transforming growth factor alpha (TGF‐α, p = 6.5 × 10−5) and BCL incidence. Analyses stratified by histological subtypes identified inverse associations for MM subtype including FGF‐2 (p = 7.8 × 10−7), TGF‐α (p = 4.08 × 10−5), fractalkine (p = 1.12 × 10−3), monocyte chemotactic protein‐3 (p = 1.36 × 10−4), macrophage inflammatory protein 1‐alpha (p = 4.6 × 10−4) and vascular endothelial growth factor (p = 4.23 × 10−5). Our results also provided marginal support for already reported associations between chemokines and diffuse large BCL (DLBCL) and cytokines and chronic lymphocytic leukemia (CLL). Case‐only analyses showed that Granulocyte‐macrophage colony stimulating factor levels were consistently higher closer to diagnosis, which provides further evidence of its role in tumor progression. In conclusion, our study suggests a role of growth‐factors in the incidence of MM and of chemokine and cytokine regulation in DLBCL and CLL.

Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- According to the statutes of the United Nations everyone has the right to know his own history, but many family trees have branches which have not yet seen the light of day because of lack of documentation. The survey is about the emigration from the south of Sweden to Denmark and Germany which took place in the shadow of the great emigration to America, which has been thoroughly documented.The survey illuminates a large amount of different sources and theories about the so called forgotten emigration. It describes the motives for the emigration, what their route looked like, where they went and what their lives developed into.The survey shows the way the mobility and rootlessness of people is viewed from a perspective of morality and what it would mean to men and women, married and unmarried, children and adults.The study also shows the effect of the powers that be on the women’s organizations, emigrant agents and immigration, in the different areas of emigration and reception.Among other things it illuminates how the structures of society on different levels handled the situation of the poor lower class. Cheap labor was set against the wish for a better life of the individual. This created a mobile seasonal work force which was not documented by the authorities. Many people stayed abroad and eventually became German and Danish citizens. It is however very difficult to map these historical seasonal travels and neutralizations due to the poor documentation of the hundreds of thousands people between Sweden and Denmark and Germany.Through different types of empirical studies this survey shows that unregistered people from Blekinge can be found in Denmark and Germany.Lastly a contemptuous view on these travelers to Denmark and Germany can be ascertained in the source material which illustrates the perspective of the powers that be.
