Tidskriftsartikel (refereegranskat)abstract
- We present a spatial omics approach that combines histology, mass spectrometry imaging and spatial transcriptomics to facilitate precise measurements of mRNA transcripts and low-molecular-weight metabolites across tissue regions. The workflow is compatible with commercially available Visium glass slides. We demonstrate the potential of our method using mouse and human brain samples in the context of dopamine and Parkinson’s disease.

- Recent molecular studies have identified substantial fungal diversity in indoor environments. Fungi and fungal particles have been linked to a range of potentially unwanted effects in the built environment, including asthma, decay of building materials, and food spoilage. The study of the built mycobiome is hampered by a number of constraints, one of which is the poor state of the metadata annotation of fungal DNA sequences from the built environment in public databases. In order to enable precise interrogation of such data – for example, “retrieve all fungal sequences recovered from bathrooms” – a workshop was organized at the University of Gothenburg (May 23-24, 2016) to annotate public fungal barcode (ITS) sequences according to the MIxS-Built Environment annotation standard (http://gensc.org/mixs/). The 36 participants assembled a total of 45,488 data points from the published literature, including the addition of 8,430 instances of countries of collection from a total of 83 countries, 5,801 instances of building types, and 3,876 instances of surface-air contaminants. The results were implemented in the UNITE database for molecular identification of fungi (http://unite.ut.ee) and were shared with other online resources. Data obtained from human/animal pathogenic fungi will furthermore be verified on culture based metadata for subsequent inclusion in the ISHAM-ITS database (http://its.mycologylab.org).

Medication communication with older adults experiencing chronic illness and polypharmacy
- 2023
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Populations in many high-income countries are ageing, with an ever-increasing proportion of the population aged 65 years or older. Despite increasingly better health in older people, susceptibility to chronic illness increase with age. As life expectancy increases, the length of time people can live with chronic illness increases correspondingly, mainly due to improved medication treatments. Decreased number of hospital beds per capita and length of stay in hospital has gained primary care an increasing role in the healthcare system, with higher demands on patients and their knowledge and abilities to manage medications and self-management.Aim: The overarching aim of this thesis was to explore how medication regimens are communicated in primary care consultations and in written discharge letters.Methods: In Study I, passive participant observations of primary care consultations were audio-recorded, transcribed and analysed using content analysis. Study II had a convergent mixed methods design. An assessment matrix, constructed based on previous research, was used to assess and quantify discharge letter content. The quantified discharge letter content, questionnaires and register data were used to calculate correlations between discharge letter content and readmission rate as well as self-rated quality of care transition. Finally, associations between discharge letter content and time to readmission were calculated both univariable and multivariable. In addition to discharge letter content, several other potential independent variables were included in the multivariable analysis.Results: Both studies show that physicians were prone to give information about medications and blood-samples or other examinations performed in advance to the consultation (Study I) or during the hospital admission (Study II). The physicians were, however, less prone to inform patients about self-management and lifestyle changes, symptoms to be aware of, and what to do in case they would appear. Communication was occasionally hindered by misunderstandings, e.g., when vague expressions or words with ambiguous meaning was used. Ambiguities e.g., arose due to dialectal disparity. Although physicians mainly communicated in plain language with patients, medication names imposed a significant problem for patients and in communication about medications. Discharge letter content was not associated to readmissions, the only significant predictor variables for time to readmission were previous admission the past 180 days and birth outside the Nordic countries. Discharge letters with more content were, on the other hand, correlated to worse self-estimated quality of care transition from hospital to home (Study II).Conclusions: Physicians informed patients about tests and examinations performed in the past time, and comprehensive information was provided about medications, both during consultations and in discharge letters. However, information about symptoms to be aware of and measures to take in case they would appear was scarce in consultations and discharge letters. In conversations where lifestyle changes were raised, the topic was quickly dropped without recommendations or offering support if the patient showed unconcern. Lifestyle changes in relation to chronic illness and medications were rarely discussed. Improved lifestyle as a means of reducing the need for medications was not discussed or informed about in discharge letters. Discharge letter content did not have any impact on readmissions.

- This paper presents an empirical study carried out in the automotive industry, with the aim to bring forward new experiences and knowledge on management of requirements in practice. Adopting a qualitative systems approach, and using multiple information sources, the requirements management process during the development of a passenger car cockpit has been mapped out. More specifically, the intention has been to identify and describe progress, changes, deviations, and compromises regarding the requirements and their fulfilment linked to the different phases of the product development. The logical reconstruction of the requirements management process is complemented with broad descriptions of associated phenomena, such as important events, organisational structures, competences, and attitudes. Findings are presented, analysed and discussed considering also factors underlying observed phenomena. Accompanying the empirical findings, the paper concludes with recommendations for constructive and efficient requirements management in practice.

Konferensbidrag (refereegranskat)abstract
- Universitetskanslerämbetet (UKÄ) ställer numera krav på svenska lärosäten att vi ska utvärdera oss själva. Vi på LTH bör då gemensamt försöka hitta sätt att uppfylla UKÄs krav som även ger de verktyg vi själva behöver för att förbättra våra utbildningars kvalitét.Hur tar vi reda på våra utbildningars styrkor och svagheter och vad vi kan göra för att förbättra dem ytterligare? Ett sätt är att undersöka hur väl studenterna uppfyller examensmålen. Vad som ska räknas som belägg för studenters måluppfyllelse är dock svårt, av flera olika skäl. Vår rekommendation blir att triangulera olika typer av belägg samt att tydligt involvera institutionerna i arbetet.

A dedicated photoelectron spectroscopy instrument for studies of catalytic reactions at pressures exceeding 1 bar
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Here, we present a new high-pressure x-ray photoelectron spectroscopy system dedicated to probing catalytic reactions under realistic conditions at pressures exceeding 1 bar. The instrument builds around the concept of a “virtual cell” in which a gasflow is directed onto the sample surface creating a local high pressure on top of the sample. This allows the instrument to maintain a low pressure of a few mbars in the main chamber, while simultaneously keeping a local pressure of around 1 bar. Synchrotron radiation based grazing incidence photoemission within ± 5° is used to enhance the surface sensitivity in the experiment. The aperture, separating the high-pressure region from the differential pumping of the electron spectrometer, consists of multiple, evenly spaced, mm sized holes matching the footprint of the x-ray beam on the sample surface. As the photo-emitted electrons are subject to strong scattering in the gas phase and the resulting signal is therefore highly dependent on the sample to aperture distance, the latter is controlled with high precision using a fully integrated manipulator that allows for sample movement with step sizes of 10 nm between 0 and –5 mm with very low vibrational amplitude. The instrumental features allows acquisition of metallic bulk spectra at He pressures up to 2.5 bar and also allows for following C1s spectra under realistic gas mixtures of CO + H2with various temperatures up to 500°C. This capability opens for studies of catalytic reactions in operandi.

Tidskriftsartikel (refereegranskat)abstract
- We present a new high-pressure x-ray photoelectron spectroscopy system dedicated to probing catalytic reactions under realistic conditions at pressures of multiple bars. The instrument builds around the novel concept of a "virtual cell" in which a gas flow onto the sample surface creates a localized high-pressure pillow. This allows the instrument to be operated with a low pressure of a few millibar in the main chamber, while simultaneously a local pressure exceeding 1 bar can be supplied at the sample surface. Synchrotron based hard x-ray excitation is used to increase the electron mean free path in the gas region between sample and analyzer while grazing incidence <5 degrees close to total external refection conditions enhances surface sensitivity. The aperture separating the high-pressure region from the differential pumping of the electron spectrometer consists of multiple, evenly spaced, micrometer sized holes matching the footprint of the x-ray beam on the sample. The resulting signal is highly dependent on the sample-to-aperture distance because photoemitted electrons are subject to strong scattering in the gas phase. Therefore, high precision control of the sample-to-aperture distance is crucial. A fully integrated manipulator allows for sample movement with step sizes of 10 nm between 0 and -5 mm with very low vibrational amplitude and also for sample heating up to 500 degrees C under reaction conditions. We demonstrate the performance of this novel instrument with bulk 2p spectra of a copper single crystal at He pressures of up to 2.5 bars and C1s spectra measured in gas mixtures of CO + H-2 at pressures of up to 790 mbar. The capability to detect emitted photoelectrons at several bars opens the prospect for studies of catalytic reactions under industrially relevant operando conditions.
