- P>Background: Previous studies have indicated that patients with obstructive sleep apnoea (OSA) have altered ventilation and lung volumes awake and the results suggest that this may be a determinant of severity of desaturations during sleep. However, little is known about regional lung aeration during sleep in patients with OSA. Methods: Twelve patients with OSA were included in the study. Computed tomography was used to study regional lung aeration during wakefulness and sleep. Lung aeration was calculated in ml gas/g lung tissue in four different regions of interest (ROI1-4), along the border of the lung from ventral to dorsal. Results: Lung aeration in the dorsal (dependent) lung region (ROI4) was lower during sleep compared to wakefulness 0 center dot 78 +/- 0 center dot 19 versus 0 center dot 88 +/- 0 center dot 19 (mean +/- SD) ml gas/g lung tissue (P = 0 center dot 005). Associations were found between awake expiratory reserve volume and change in lung aeration from wakefulness to sleep in ROI4 (r = -0 center dot 69; P = 0 center dot 012). In addition, the change in lung aeration in the dorsal region correlated to sleep time (r = 0 center dot 69; P = 0 center dot 014) but not to time in supine position. The difference in lung aeration between inspiration and expiration (i.e. ventilation), was larger in the ventral lung region when expressed as ml gas per g lung tissue. In two patients it was noted that, during on-going obstructive apnoea, lung aeration tended to be increased rather than decreased. Conclusions: Aeration in the dorsal lung region is reduced during sleep in patients with OSA. The decrease is related to lung volume awake and to sleep time.

Incidence of and risk factors for neonatal morbidity after active perinatal care : extremely preterm infants study in Sweden (EXPRESS)
- 2010
-
In: Acta Paediatrica. - : Wiley. - 0803-5253 .- 1651-2227. ; 99:7, s. 978-992
-
Journal article (peer-reviewed)abstract
- Aims: The aim of this study was to determine the incidence of neonatal morbidity in extremely preterm infants and to identify associated risk factors. Methods: Population based study of infants born before 27 gestational weeks and admitted for neonatal intensive care in Sweden during 2004-2007. Results: Of 638 admitted infants, 141 died. Among these, life support was withdrawn in 55 infants because of anticipation of poor long-term outcome. Of 497 surviving infants, 10% developed severe intraventricular haemorrhage (IVH), 5.7% cystic periventricular leucomalacia (cPVL), 41% septicaemia and 5.8% necrotizing enterocolitis (NEC); 61% had patent ductus arteriosus (PDA) and 34% developed retinopathy of prematurity (ROP) stage >= 3. Eighty-five per cent needed mechanical ventilation and 25% developed severe bronchopulmonary dysplasia (BPD). Forty-seven per cent survived to one year of age without any severe IVH, cPVL, severe ROP, severe BPD or NEC. Tocolysis increased and prolonged mechanical ventilation decreased the chances of survival without these morbidities. Maternal smoking and higher gestational duration were associated with lower risk of severe ROP, whereas PDA and poor growth increased this risk. Conclusion: Half of the infants surviving extremely preterm birth suffered from severe neonatal morbidities. Studies on how to reduce these morbidities and on the long-term health of survivors are warranted.

Prognostic scoring systems for myelodysplastic syndromes (MDS) in a population-based setting : a report from the Swedish MDS register
- 2018
-
In: British Journal of Haematology. - : Wiley. - 0007-1048 .- 1365-2141. ; 181:5, s. 614-627
-
Journal article (peer-reviewed)abstract
- The myelodysplastic syndromes (MDS) have highly variable outcomes and prognostic scoring systems are important tools for risk assessment and to guide therapeutic decisions. However, few population-based studies have compared the value of the different scoring systems. With data from the nationwide Swedish population-based MDS register we validated the International Prognostic Scoring System (IPSS), revised IPSS (IPSS-R) and the World Health Organization (WHO) Classification-based Prognostic Scoring System (WPSS). We also present population-based data on incidence, clinical characteristics including detailed cytogenetics and outcome from the register. The study encompassed 1329 patients reported to the register between 2009 and 2013, 14% of these had therapy-related MDS (t-MDS). Based on the MDS register, the yearly crude incidence of MDS in Sweden was 2.9 per 100000 inhabitants. IPSS-R had a significantly better prognostic power than IPSS (P < 0001). There was a trend for better prognostic power of IPSS-R compared to WPSS (P=0.05) and for WPSS compared to IPSS (P=0.07). IPSS-R was superior to both IPSS and WPSS for patients aged <= 70years. Patients with t-MDS had a worse outcome compared to de novo MDS (d-MDS), however, the validity of the prognostic scoring systems was comparable for d-MDS and t-MDS. In conclusion, population-based studies are important to validate prognostic scores in a real-world' setting. In our nationwide cohort, the IPSS-R showed the best predictive power.

Health-Related Quality of Life, Depression and Anxiety Correlate with the Degree of Hirsutism
- 2013
-
In: Dermatology. - : Karger. - 1018-8665 .- 1421-9832. ; 227:3, s. 278-284
-
Journal article (peer-reviewed)abstract
- Background: Hirsutism has a negative impact on womens quality of life. The relation between quality of life, anxiety, depression and the level of hairiness has not been described. Aims: To investigate the correlations between the levels of hairiness, quality of life, anxiety and depression. Methods: 200 patients from Malmo, Orebro and Uppsala, who had been in contact with the clinics for problems with excessive hair growth, were invited to answer a self-administered questionnaire including sociodemographic questions, EQ-5D index score, Dermatology Life Quality Index (DLOI), Hospital Anxiety and Depression Scale (HADS) and Ferriman-Gallwey scale (F-G); of these, 127 women participated in the study. Results: The mean values were: EQ-5D index 0.73 (SD = 0.27), EQ visual analogue scale 61.0 (SD = 22.6), HADS-anxiety 9.5 +/- 5.3 and HADS-depression 6.5 +/- 4.6. The mean DLQI was 11.8 +/- 8.4, indicating a very large effect on patients lives. All were significantly correlated with the amount of hairiness. Conclusions: Higher levels of hair growth were significantly correlated with a lower level of quality of life and symptoms of both anxiety and depression.

Hirsutism and quality of life with aspects on social support, anxiety and depression
- 2013
-
Doctoral thesis (other academic/artistic)abstract
- Hirsutism is excessive hair growth in women. The prevalence is estimated at 5%. The aim of this thesis was to describe different aspects of how life is affected for women suffering from hirsutism. Both qualitative and quantitative methods were used. Study I showed that hirsutism deeply affects women’s experiences of their bodies in a negative way and was experienced as a life sorrow. In Study II the patient-physician relationship was described. The patient-physician relationship from the patient’s perspective was suboptimal, as most meetings included feelings of being rejected and even humiliation. In Study III the aim was to translate and psychometrically evaluate an instrument that measures perceived social support, “The Multidimensional Scale of Perceived Social Support” (MSPSS). The translation was performed according to WHO:s official process, and validation was performed in a sample that consisted of 281 participants, 127 women with hirsutism (main sample) and 154 nursing students. MSPSS had good psychometric properties with regard to factor structure, construct validity, internal consistency and reproducibility. Study IV described different aspects of HRQoL in the main sample, the correlation of anxiety, depression, level of hairiness, age and BMI. The F-G scores were dichotomized into minor (F-G ≤14) and major (F-G≥15) hair growth. Higher levels of hair growth were significantly correlated to a lower level of QoL measured by DLQI, EQ-5D and symptoms of both anxiety and depression measured by HADS. Study V investigated if social support was associated with quality of life and outcome of HRQoL compared to a reference group of women (n=1115). SF-36, the MSPSS and the F-G scale were used. Compared to the reference group, women with hirsutism reported lower quality of life in all dimensions of SF-36 (p<0.01) The dimension most affected was vitality (VT=41.2), which had a lower value than has been reported for patients with MS and myasthenia gravis. A Multiple Regression Analysis showed a significant relation between quality of life and social support, indicating its importance for the ability to adapt, in spite of low quality of life.

Social support : an important factor for quality of life in women with hirsutism
- 2014
-
In: Health and Quality of Life Outcomes. - : Springer Science and Business Media LLC. - 1477-7525 .- 1477-7525. ; 12
-
Journal article (peer-reviewed)abstract
- Background: Women with hirsutism have reported imparied health and health-related quality of life (HRQoL). Social support is a factor that might increase HRQoL in chronic diseases, but little is known about this association among women with hirsutism. Aim: The aim of the study was to describe social support and explore its association with HRQoL among women with hirsutism. A further aim was to compare HRQoL in women with hirsutism with a Swedish normal population. Methods: A questionnaire including socio-demographic questions, Short-Form Health Survey (SF-36), the Multidimensional Scale of Perceived Social Support (MSPSS), and a self-estimation of hairiness using the Ferriman-Gallway scale (F-G scale) was answered by 127 women with hirsutism. Results: Multiple regression analyses showed significant associations between social support and all health dimensions in the SF-36, also after the model was adjusted for age, hairiness and body mass index. Compared to the normal Swedish population, women with hirsutism reported significantly lower HRQoL in all dimensions of the SF-36 (p < 0.01). Conclusions: There is a significant positive association between social support and HRQoL, demonstrating its importance for the ability to adapt to problems associated with hirsutism. As women with hirsutism reported poorer HRQoL compared to the normal population, social support may be a factor to consider in clinical practice.

Social support and quality of life among women diagnosed with hirsutism
-
Other publication (other academic/artistic)abstract
- Background: Women with hirsutism report more anxiety, depression and lower quality of life. However, their social situation with a family and employment does not differ from other women. Social support is a factor that might increase quality of life in chronic diseases. Little is known about social support and skin diseases.Objectives: The aim was to evaluate the relation between health-related quality of life and social support among women with hirsutism.Methods: A questionnaire including socio-demographic questions, Short Form 36 (SF-36), the Multidimensional Scale of Perceived Social Support (MSPSS) and a self-estimation of hairiness using the Ferriman-Gallway scale (F-G scale) was filled out by 127. MSPSS has three sub-scales (family, friends, significant others) and a total score, that was used for calculation.Results: Compared to a Swedish population based reference group women with hirsutism reported lower quality of life in all dimensions of SF-36 (p<0.01). Multiple regression analysis showed a significant correlation between the MSPSS and SF-36 in the initial and adjusted model.Conclusions: There is a significant positive relation between quality of life and social support, demonstrating its importance for the ability to adapt to problems associated with hirsutism. It can be postulated that social support is important for the quality of life in chronic skin diseases wich merits further investigations.

Absolute lung size and the sex difference in breathlessness in the general population
- 2018

Journal article (peer-reviewed)abstract
- Background Breathlessness is associated with major adverse health outcomes and is twice as common in women as men in the general population. We evaluated whether this is related to their lower absolute lung volumes. Cross-sectional analysis of the population-based Swedish CardioPulmonarybioImage Study (SCAPIS) Pilot, including static spirometry and diffusing capacity (n = 1,013; 49% women). Breathlessness was measured using the modified Medical Research Council (mMRC) scale and analyzed using ordinal logistic regression adjusting for age, pack-years of smoking, body mass index, chronic airway limitation, asthma, chronic bronchitis, depression and anxiety in all models. Breathlessness was twice as common in women as in men; adjusted odds ratio (OR) 2.20 (95% confidence interval, 1.32-3.66). Lower absolute lung volumes were associated with increased breathlessness prevalence in both men and women. The sex difference in breathlessness was unchanged when adjusting for lung function in %predicted, but disappeared when controlling for absolute values of total lung capacity (OR 1.12; 0.59-2.15), inspiratory capacity (OR 1.26; 0.68-2.35), forced vital capacity (OR 0.84; 0.42-1.66), forced expiratory volume in one second (OR 0.70; 0.36-1.35) or lung diffusing capacity (OR 1.07; 0.58-1.97). In the general population, the markedly higher prevalence of breathlessness in women is related to their smaller absolute lung volumes.

Journal article (peer-reviewed)abstract
- Breathlessness is common in the population and can be related to a range of medical conditions. We aimed to evaluate the burden of breathlessness related to different medical conditions in a middle-aged population.Cross-sectional analysis of the population-based Swedish CArdioPulmonary bioImage Study of adults aged 50-64 years. Breathlessness (modified Medical Research Council [mMRC] ≥ 2) was evaluated in relation to self-reported symptoms, stress, depression; physician-diagnosed conditions; measured body mass index (BMI), spirometry, venous haemoglobin concentration, coronary artery calcification and stenosis [computer tomography (CT) angiography], and pulmonary emphysema (high-resolution CT). For each condition, the prevalence and breathlessness population attributable fraction (PAF) were calculated, overall and by sex, smoking history, and presence/absence of self-reported cardiorespiratory disease.We included 25,948 people aged 57.5 ± [SD] 4.4; 51% women; 37% former and 12% current smokers; 43% overweight (BMI 25.0-29.9), 21% obese (BMI ≥ 30); 25% with respiratory disease, 14% depression, 9% cardiac disease, and 3% anemia. Breathlessness was present in 3.7%. Medical conditions most strongly related to the breathlessness prevalence were (PAF 95%CI): overweight and obesity (59.6-66.0%), stress (31.6-76.8%), respiratory disease (20.1-37.1%), depression (17.1-26.6%), cardiac disease (6.3-12.7%), anemia (0.8-3.3%), and peripheral arterial disease (0.3-0.8%). Stress was the main factor in women and current smokers.Breathlessness mainly relates to overweight/obesity and stress and to a lesser extent to comorbidities like respiratory, depressive, and cardiac disorders among middle-aged people in a high-income setting-supporting the importance of lifestyle interventions to reduce the burden of breathlessness in the population.
