- Background: In interview studies, men under surveillance for screening-detected abdominal aortic aneurysms have reported ambivalence towards this diagnosis: the knowledge was welcomed together with worries, feelings of anxiety and existential thoughts about life's fragility and mortality due to the diagnosis. Previous surveys about health-related quality of life aspects among men under surveillance for screening-detected aneurysm have all used generic patient-reported outcomes. Therefore, the aim of this study was to extend the core-questionnaire Consequences of Screening for use in abdominal aortic aneurysm screening by testing for comprehension, content coverage, dimensionality, and reliability.Methods: In interviews, the suitability, content coverage, and relevance of the core-questionnaire Consequences of Screening were tested on men under surveillance for a screeningdetected abdominal aortic aneurysm. The results were thematically analysed to identify the key consequences of abnormal screening results. Item Response Theory and Classical Test Theory were used to analyse data. Dimensionality, differential item functioning, local response dependency and reliability were established by item analysis, examining the fit between item responses and Rasch models.Results: The core-questionnaire Consequences of Screening was found to be relevant for men offered regular follow-up of an asymptomatic screening-detected abdominal aortic aneurysm.Fourteen themes especially relevant for men diagnosed with a screening-detected abdominal aortic aneurysm were extracted from the interviews: 'Uncertainty about the result of the ultra sound examination', 'Change in body perception', 'Guilt', 'Fear and powerlessness', 'Negative experiences from the examination', 'Emotional reactions', 'Change in lifestyle', 'Better not knowing', 'Fear of rupture', 'Sexuality', 'Information', 'Stigmatised', 'Self-blame for smoking', 'Still regretful smoking'. Altogether, 55 new items were generated: 3 were single items and 13 were only relevant for former or current smokers. 51 of the 52 items belonging to a theme were confirmed to fit Rasch models measuring fourteen different constructs. No differential item functioning and only minor local dependency was revealed between some of the 51 items.Conclusions: The reliability and the dimensionality of a condition-specific measure with high content validity for men under surveillance for a screening-detected abdominal aortic aneurysm have been demonstrated. This new questionnaire called COS-AAA covers in two parts the psychosocial experience in abdominal aortic aneurysm screening.

- Background: In order to reduce the incidence of abdominal aortic aneurysm rupture and mortality, the Swedish Medical Council has introduced a national abdominal aortic aneurysm (AAA) screening program that offers ultrasound examination of 65-year-old men. Screening programmes of AAA may confer both benefits and harms. The study aim was to investigate the psychosocial consequences of AAA screening among men with screening-detected AAA as compared to men identified as AAA-negative at screening, using an AAA-specific questionnaire. Methods: This cross-sectional study investigated the psychosocial consequences of AAA screening mea-sured with a condition-specific questionnaire. This study focused on the Experience of the Diagnosis and the Screening Procedure in terms of Anxiety, Sense of Dejection and Existential Values. One hundred and fifty-eight men with AAA (63%) and 275 with normal aorta size (55%) completed the diagnosis-specific questionnaire. Results: Ninety-six percent of men with screening detected AAA did not regret the screening examination, the corresponding figure for controls being 99.6%. Seventy percent of AAA patients were surprised that something was wrong in their body. Some (85%) of men with AAA were current or previous smokers, about half of them (45%) felt guilty about it and 78% of the current smokers in the AAA group had considered stopping smoking. Both groups considered changing lifestyle, although at a higher rate (32%) among AAA cases than controls (20%), with differences both in intention to change their ways to exercise ( p = 0.019) and food intake ( p = 0.001). Intergroup differences were identified for the majority of items as captured by the questionnaire where men identified with AAA reported more negative psycho-social consequences for all evaluated items except for the items: Regret of the screening examination ( p = 0.069) and feeling terrified ( p = 0.10). Fifty-one percent of AAA cases stated that they feared rupture, and 12% were anxious about rupture dur-ing sexual activity whereas 57% were worried about rupture during intense physical activity. Conclusion: Men who were diagnosed with AAA reported more psychosocial consequences compared to controls; still only a minority of AAA cases reported psychosocial consequences in greater occurrence. To some degree, men with AAA also feared rupture during various types of activities. There appears to be a need for improved patient information and easy access to caregivers for men with screening-detected AAA, which might help to reduce psychosocial consequences associated with the diagnosis.(c) 2023 Society for Vascular Nursing, Inc.

- Aim To describe the structure, content, and the communicative and pedagogic strategies in discharge consultations between patients and professionals after colorectal cancer surgery. Background Both nurses and surgeons play an important role in preparing patients for discharge from hospital following surgery for colorectal cancer (CRC). Design An explorative quantitative and qualitative research based on analysis of transcriptions of 13 audio-taped discharge consultations between patients and nurses and patients and surgeons conducted between January - March 2012. Methods In the quantitative analysis, the structure of each consultation was described in phases, subtopics, and main topics. The proportion of the main topics in relation to the whole conversation was counted in percentages. The text from the consultations was then analysed qualitatively with the support from Ricoeur's theory of interpretation. Results The language constituted the essence in the consultations regardless of other communicative and pedagogical strategies. The pedagogic strategies used were explanation model, information transfer, task orientation, and dialogue. Topics occurring in the consultations were Operation, Symptoms, Medication, Thromboprophylaxis, Recovery after surgery, Bowel function, Spreading, and Follow-up. The surgeons and nurses used similar topics, but the surgeons used more communicative and pedagogic strategies. Conclusion Language was fundamental for communication and independent of the communicative and pedagogical strategies. Using preparedness communication more consistent in discharge consultation can help patients to better understand the recovery process after CRC surgery and regain control over their life. It is important that the consultations build on the patient as an active and learning person.

- Purpose The aims of the study were to develop and psychometrically evaluate a patient-reported outcome instrument for the measurement of preoperative preparedness in patients undergoing surgery for colorectal cancer. Methods This study was conducted in two stages: a) instrument development (item generation, construction of items and domains), empirical verification and b) instrument evaluation. A questionnaire with 28 items measuring preparedness for surgery was developed covering four domains and was tested for content validity with an expert panel and with patients. Psychometric testing of the questionnaire was conducted on 240 patients undergoing elective surgery for colorectal cancer. Results The scale content validity index of the preparedness items was 0.97. The final version consisted of 24 items measuring 4 subscales: Searching for and making use of information, Understanding and involvement in the care process, Making sense of the recovery process and Support and access to medical care. Confirmatory factor analysis revealed good model fit with standardized factor loadings ranging from 0.58 to 0.97. A well-fitting second-order factor model provided support for a total preparedness score with second-order factor loadings ranging from 0.75 to 0.93. The ordinal alpha values of the four latent factors ranged from 0.92 to 0.96, indicating good internal consistency. The polyserial correlations with the total score were 0.64 (p<0.01) for the overall preparedness question and 0.37 (p<0.01) for overall well-being. Conclusion The Swedish Preparedness for Colorectal Cancer Surgery Questionnaire for use in the preoperative phase demonstrated good psychometric properties based on a sound conceptualization of preparedness. © 2016 Elsevier Ltd

Structure and content in consultations with patients undergoing surgery for colorectal cancer
- 2013

Journal article (peer-reviewed)abstract
- Purpose: To explore the structure and content of pre-planned consultations as part of the care and treatment of patients undergoing surgery for colorectal cancer. Methods: The study was based on 50 transcripts of audio-recorded pre-planned consultations between seven patients and 36 healthcare professionals from the time of diagnosis, pre-operative consultation, discharge consultation and pathology report in a colorectal unit. Results: The spread of consultation time between professions was considerable. Total mean consultation time for patients during the care process (7 consultations/patient) was 111 mm (range 83-191). The mean consultation time for surgeons was 18 min (7-40), anaesthesiologists 12 min (5-18) and nurses 14 min (5-49). Patients took up 40% of the word space, healthcare professionals used 59% and significant others 1%. Word space changed in such a way that the patient became more active towards the final consultation. Neither during the diagnosis consultation nor during the pre-operative consultation did the patients meet the operating surgeon. Six major subjects emerged: general health, diagnosis, surgical procedure, pre-operative preparations, recovery and treatment and follow-up. Conclusions: There is a need for clearer structure in the consultations. Most consultations lacked a clear introduction to the subject of the conversation. The study makes it possible to develop methods and structure for supporting conversations in which the patient is given space to help with the difficult issues present after undergoing surgery for colorectal cancer. The study also contributes to providing knowledge of how to organise surgical consultations in order to optimise person-centeredness, teamwork and clinical efficiency. (C) 2013 Elsevier Ltd.

Journal article (peer-reviewed)abstract
- Antimicrobial surfaces are important in medical, clinical, and industrial applications, where bacterial infection and biofouling may constitute a serious threat to human health. Conventional approaches against bacteria involve coating the surface with antibiotics, cytotoxic polymers, or metal particles. However, these types of functionalization have a limited lifetime and pose concerns in terms of leaching and degradation of the coating. Thus, there is a great interest in developing long-lasting and non-leaching bactericidal surfaces. To obtain a bactericidal surface, we combine micro and nanoscale patterning of borosilicate glass surfaces by ultrashort pulsed laser irradiation and a non-leaching layer-by-layer polyelectrolyte modification of the surface. The combination of surface structure and surface charge results in an enhanced bactericidal effect against both Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli bacteria. The laser patterning and the layer-by-layer modification are environmentally friendly processes that are applicable to a wide variety of materials, which makes this method uniquely suited for fundamental studies of bacteria-surface interactions and paves the way for its applications in a variety of fields, such as in hygiene products and medical devices.

Journal article (peer-reviewed)abstract
- A contact-active antibacterial approach based on the physical adsorption of a cationic polyelectrolyte onto the surface of a cellulose material is today regarded as an environment-friendly way of creating antibacterial surfaces and materials. In this approach, the electrostatic charge of the treated surfaces is considered to be an important factor for the level of bacteria adsorption and deactivation/killing of the bacteria. In order to clarify the influence of surface charge density of the cellulose on bacteria adsorption as well as on their viability, bacteria were adsorbed onto cellulose model surfaces, which were modified by physically adsorbed cationic polyelectrolytes to create surfaces with different positive charge densities. The surface charge was altered by the layer-by-layer (LbL) assembly of cationic polyvinylamine (PVAm)/anionic cellulose nanofibril/PVAm onto the initially differently charged cellulose model surfaces. After exposing the LbL-treated surfaces to Escherichia coli in aqueous media, a positive correlation was found between the adsorption of bacteria as well as the ratio of nonviable/viable bacteria and the surface charge of the LbL-modified cellulose. By careful colloidal probe atomic force microscopy measurements, it was estimated, due to the difference in surface charges, that interaction forces at least 50 nN between the treated surfaces and a bacterium could be achieved for the surfaces with the highest surface charge, and it is suggested that these considerable interaction forces are sufficient to disrupt the bacterial cell wall and hence kill the bacteria.

Journal article (peer-reviewed)abstract
- Diamond-Blackfan anaemia (DBA) is a constitutional erythroblastopenia characterized by absent or decreased erythroid precursors. The disease, previously mapped to human chromosome 19q13, is frequently associated with a variety of malformations. To identify the gene involved in DBA, we cloned the chromosome 19q13 breakpoint in a patient with a reciprocal X;19 chromosome translocation. The breakpoint occurred in the gene encoding ribosomal protein S19. Furthermore, we identified mutations in RPS19 in 10 of 40 unrelated DBA patients, including nonsense, frameshift, splice site and missense mutations, as well as two intragenic deletions. These mutations are associated with clinical features that suggest a function for RPS19 in erythropoiesis and embryogenesis.

En båge genom tiden - ritualer kring en göteborgshistoria. Om Flickläroverket i Artisten
- 2024
-
Editorial collection (other academic/artistic)abstract
- 1929 bildades Göteborgs första Högre allmänna läroverk för Flickor – Flickläroverket som fick en byggnad 1935 i det kulturella centrumet, Götaplatsen. Efter några år som Kjellbergska gymnasiet, sedan Komvux, blev byggnaden del av Artisten, Högskolan för scen och musik, HSM 1992. Byggnaden har burit kvinnors utbildning, konst och kultur över många generationer, en minneskedja som nu är bruten. Boken - En båge genom tiden – ritualer kring en göteborgshistoria – en konst- och forskningsantologi – är resultatet av de offentliga minnesdagar där de deltagande drygt 200 kvinnorna (70– 97 år) som varit elever på Flickläroverket, studenter vid Artisten, konstnärer och forskare – bidrog till och deltog i gestaltande ritualer, minnesrum, dans, utställningar och samtal som gav liv åt en utbildningskultur och konst som berört samhället i generationer. I boken bidrar ett 20-tal Göteborgsbaserade konstnärer och forskare med olika perspektiv på byggnadens poetiska, sociala och konstnärliga dimensioner. Bland annat beskrivs återskapandet av Bågdansen, som dansades varje år vid Lucia mellan 1934-1972. Här beskrivs även den medie-debatt som ledde till räddningen av målningen Dansen av Nils Nilsson från 1935 och hur nedtagningen gick till. Tillsammans med ett rikt foto- och bildmaterial, filmdokumentationer och ett ljudarkiv utgör boken ett tidsdokument där konst fungerar som minnesbärare över tid och rum.
