Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this thesis is to study representations of identity and (in)visibility in Swedish lesbian novels written in the 1930s, and to provide a summary of Swedish lesbian literature up to the early 21st century. This study has been done through a close reading primarily of Charlie by Margareta Suber (1932), Fröknarna von Pahlen by Agnes von Krusenstjerna (1930–1935) and Kris by Karin Boye (1934). Lesbian literature is discussed as a loose category, a construction which can be used as an analytical tool in a conscious and reflexive way, with its basis in the categories of author, text and reader. In short, I define lesbian literature as novels written by women, about lesbian figures and/or relationships, and for lesbian readers in the sense that the literature depicts lesbians from an insider’s perspective. As regards the period before 1930, the focus is on romantic friendship and the excitement zone when the romantic friendship becomes a sexual one, as seen in the fictitious case of Sin fars dotter (1920) by Lydia Wahlström. Sexological theories, the image of “the new woman” and changes to the law all colour the first half of the 20th century. This is seen in Charlie by Margareta Suber, where the author makes use of many such explanations in her creation of a lesbian figure. A reading of Fröknarna von Pahlen by Agnes von Krusenstjerna shows an intricate pattern of relationships at its heart. My analysis charts several same-sex couples, a lesbian single woman and two collectives; that is to say, the female collective and the male homosexual collective. The relationships between women are many-faceted and include everything from romantic friendship, kinship and sensualism to eroticism and shared parenthood. In my analysis of Kris by Karin Boye, I focus on Malin, the main character, and the development of her sense of identity, in which the struggle between the language of the world around her and her own emotional experience of love for a woman is a central theme. After the 1930s, the historical context changed in terms of everything from decriminalisation in 1944 via the homophobic panic of the 1950s to the impact of queer theory in the 1990s. Swedish lesbian literature addresses everything from crime of passion (murder) to the coming out process of young women. There exists in all novels from the 1930s an interplay that is (in)visible: the characters or lesbian relationships depicted are both visible and invisible at the same time. The characters are more or less aware of the potential risks attached to being visible as a lesbian, and often they do not notice themselves when this occurs. During the course of the 20th century, (in)visibility becomes replaced by openness and secrecy, and the visibility of the lesbian characters is politicised.

- Background: Maximum exercise workload (WMAX) is today assessed as the first part of Cardiopulmonary Exercise testing. The WMAX test exposes patients with COPD, often having cardiovascular comorbidity, to risks. Our research project was initiated with the final aim to eliminate the WMAX test and replace this test with a predicted value of WMAX, based on a prediction algorithm of WMAX derived from multicentre studies. Methods: Baseline data (WMAX, demography, lung function parameters) from 850 COPD patients from four multicentre studies were collected and standardized. A prediction algorithm was prepared using Random Forest modelling. Predicted values of WMAX were used in a new WMAX test, which used a linear increase in order to reach the predicted WMAX within 8 min. The new WMAX test was compared with the standard stepwise WMAX test in a pilot study including 15 patients with mild/moderate COPD. Results: The best prediction algorithm of WMAX included age, sex, height, weight, and six lung function parameters. FEV1 and DLCO were the most important predictors. The new WMAX test had a better correlation (R2 = 0.84) between predicted and measured WMAX than the standard WMAX test (R2 = 0.66), with slopes of 0.50 and 0.46, respectively. The results from the new WMAX test and the standard WMAX test correlated well. Conclusion: A prediction algorithm based on data from four large multicentre studies was used in a new WMAX test. The prediction algorithm provided reliable values of predicted WMAX. In comparison with the standard WMAX test, the new WMAX test provided similar overall results.

- Two new protocols have been developed for bicycle exercise testing in chronic obstructive pulmonary disease (COPD) with an individualized cardiopulmonary exercise test (ICPET) and subsequent customized endurance test (CET), which generate less interindividual spread in endurance time compared with the standard endurance test. Main objectives of this study were to improve the prediction algorithm for WMAX for the ICPET and validate the CET by examining treatment effects on exercise performance of indacaterol/glycopyrronium (IND/GLY) compared with placebo. Methods: COPD patients, with forced expiratory volume in 1 s (FEV1) 40–80% predicted, were recruited. Pooled baseline data from two previous studies (n = 38) were used for the development of an improved WMAX prediction algorithm. Additional COPD patients (n = 14) were recruited and performed the ICPET, using the new prediction formula at visit 1. Prior to the CET at visits 2 and 3, they were randomized to a single dose of IND/GLY (110/50 µg) or placebo. Results: The improved multiple regression algorithm for WMAX includes diffusing capacity for carbon monoxide (DLCO), FEV1, sex, age and height and correlated to measured WMAX (R2 = 0.89 and slope = 0.89). Treatment with IND/GLY showed improvement in endurance time versus placebo, mean 113 s [95% confidence interval (CI): 6–220], p = 0.037, with more prominent effect in patients with FEV1 < 70% predicted. Conclusion: The two new protocols for ICPET (including the new improved algorithm) and CET were retested with consistent results. In addition, the CET showed a significant and clinically relevant prolongation of endurance time for IND/GLY versus placebo in a small number of patients.

- Purpose: For exercise testing of COPD patients, a standard endurance test (ET) with constant workload is recommended. The test suffers from large inter-individual variability and need for large sample sizes in order to evaluate treatment effects. Methods: A new protocol for ET in COPD was designed. In contrast to the standard ET, the new ET involved an increasing workload in order to reduce the standard deviation of endurance time. Two new ETs were compared with the standard ET. In Study A, the new ET started at 75% of the patient’s maximum workload (WMAX) and increased stepwise with 3%/2 min until exhaustion. Study B started at 70% of WMAX and increased linearly with 1%/ min. Results: In Study A, that included 15 patients, the standard deviation and range for endurance time and work capacity were narrower for the new versus the standard ET. However, the higher mean workload at end and the low mean work capacity relative to the standard ET indicated that the stepwise increase was too aggressive. In Study B, that included 18 patients, with a modified protocol, the averages for endurance time, workload at end and work capacity were similar for new and standard ET, while the standard deviations and ranges for endurance time and work capacity were kept more narrow in the new ET. The variances for endurance time were not equal between the standard ET and the two new ETs (p<0.05 for both according to Levene’s test). Conclusion: The new ET reduced the number of patients with extreme endurance times (short and long) compared to the standard test. The new test showed a significant lower variance for endurance time, which potentially can lead to fewer patients needed in com-parative studies. The overall best results were observed with a low linear increase during endurance.
