- The general aim was to meet the need for empirical comparative studies of health-related quality of life (HRQoL) assessment instruments, by evaluating and comparing the psychometric properties and results of three different, widely used, generic HRQoL instruments in a population sample. The specific aims were to evaluate the subscales of the different instruments that measure the same domain and to assess the association between the HRQoL measures and a single-item self-rated health scale.An observational cross-sectional study.A population-based sample from Gothenburg, Sweden, was studied in 2008 in the WHO MONItoring of trends and determinants for CArdiovascular disease.A total of 414 subjects were included, 77% women, age range 39-78 years.The Nottingham Health Profile (NHP), the Short Form-36 questionnaire (SF-36), the Psychological General Well-Being Index (PGWB) and a self-rated health scale were used.Scores were analysed for their psychometric properties, internal consistency (Cronbach's α), construct validity (Spearman's rank correlations and R2 coefficients) and discriminative ability for the presence of self-rated ill-health.PGWB and SF-36 had higher Cronbach's α scores than NHP. All correlations calculated between the subscales that were conceptually similar were significant (p<0.01). All subscales could differentiate the presence of self-rated ill-health according to the self-rated health scale (p<0.001). The self-rated health scale correlated strongly with all of the three HRQoL instruments used.There was a high concordance between the instruments within each domain that was conceptually similar. All three HRQoL instruments (PGWB, SF-36 and NHP) could discriminate the presence of self-rated ill-health. The simple and quick self-rated health scale correlated strongly with the more time-consuming PGWB, SF-36 and NHP. The result supports the existence of a strong association between the self-rated health scale and HRQoL in the general population.

- The factors that affect the Health-Related Quality of Life (HRQoL) of women with Turner Syndrome (TS) are controversial.The aim was to describe the HRQoL of women with TS with a focus on how given growth hormone (GH) treatment and comorbidity influence HRQoL in adulthood, and to compare HRQoL of women with TS with that of women in the general population.Longitudinal cohort study, up to 20 years.The Turner Center at the Section for Endocrinology and Department of Reproductive Medicine at Sahlgrenska University Hospital, Gothenburg, Sweden.Women with TS, n=200, age range 16-78 yrs, were included consecutively and monitored every fifth year between 1995 and 2018. Women from the WHO-MONICA project were used as reference populations.HRQoL was measured using the Psychological General Well-Being index (PGWB) and the Nottingham Health Profile (NHP). Associations with somatic variables were assessed using longitudinal linear regression models.HRQoL was not associated with GH treatment in TS in spite of a mean 5.7 cm taller height. HRQoL was only associated with height per se in one of 13 subscales (p<0.01). HRQoL was negatively affected by higher age, higher age at diagnosis, and hearing impairment in TS. Women with TS reported a similar HRQoL to the reference population.No association between previous GH treatment and HRQoL was found during the up to 20-yrs of follow-up in women with TS. HRQoL of women with TS and the reference population was similar.

- Bariatric surgery can lead to nutrient deficiencies. Gastric by-pass (GBP) entails restriction and malabsorption, whereas, vertical banded gastroplasty (VBG) is only restrictive.The objective of this study is to study whether GBP-patients develop iodine deficiency from malabsorption, and if GBP- and VBG-patients develop lower 24-h urinary iodine excretion (24-UIE) than obese non-operated controls (OB-controls) due to lower iodine intake.The Swedish Obese Subjects (SOS) study is a prospective, non-randomized study of 4047 obese patients included 1987-2001, who chose bariatric surgery or non-surgical treatment. SOS-groups were compared at baseline, after 2 and 10years and with population-based subsamples (MONICA-controls).One hundred eighty-eight GBP-patients were matched with 188 VBG-patients and 188 OB-controls and with three subgroups from 412 MONICA-controls.Primary outcome was 24-UIE. Secondary outcomes were iodine intake, iodine supplementation, TSH, FT4, and thyroid morbidity.At baseline, median 24-UIE was higher in GBP-patients, VBG-patients and OB-controls than in MONICA-controls (214, 201, 203 and 137μg/day, p<0.001). At 10years, 24-UIE in GBP-patients (161μg/day) and VBG-patients (149μg/day) was lower compared with baseline (p<0.01) and OB-controls (189μg/day, p<0.01), but similar to 24-UIE in MONICA-controls (137μg/day). The 10-year-dietary iodine intake was similar in GPB-patients and OB-controls, but higher in VBG-patients. Iodine supplementation was taken by 0-9% in SOS-groups.After surgery, GBP- and VBG-patients did not suffer from iodine deficiency, but both groups had lower iodine status than OB-controls. Dietary supplements recommended after bariatric surgery do not need to include iodine, in iodine sufficient countries.clinicaltrials.gov : NCT01479452.

- Context Obesity is considered to have a detrimental impact on health-related quality of life (HRQoL). Objective To compare HRQoL in a well-defined group of people with obesity with a population-based control group from the general public. Design Observational cross-sectional cohort study with a reference population. Setting The Regional Obesity Center at the Department of Medicine at Sahlgrenska University Hospital, Gothenburg, Sweden. Participants People with obesity (n = 1122) eligible for surgical and non-surgical obesity treatment in routine care were included consecutively between 2015 and 2017 into the BASUN study. Men and women from the WHO-MONICA-GOT project were used as a reference population (n = 414). Main outcome measures HRQoL was measured with the RAND-36/Short Form-36 questionnaire (SF-36) and a Visual Analogue Scale (VAS) for self-related health (SRH). Prescription drugs for hypertension, diabetes mellitus, depression, and anxiety were taken as a proxy for these conditions. Results People with obesity rated their overall HRQoL lower than the reference population according to the SRH-VAS. Lower scores were reported on physical and social functioning, vitality, general and mental health after adjustment for age and use of prescription drugs (considered a proxy for burden of disease, or comorbidities) using the RAND-36/SF-36 questionnaire. Use of some psychopharmacological agents was more common in patients with obesity. Conclusion People with obesity seeking help with weight reduction are more likely to have lower physical and mental self-reported HRQoL than the general population.

Tidskriftsartikel (refereegranskat)abstract
- Introduction Persons living with obesity treated with bariatric surgery are at a high risk of developing nutritional deficiencies. The primary aim of this observational cohort study was to compare vitamin D levels in patients two years after bariatric surgery (Roux-en-Y gastric bypass/ RYGB and sleeve gastrectomy/SG) with a very low-energy diet (VLED). The same subjects were also compared with a population sample from the same region at baseline. The primary hypothesis was that surgery, especially RYGB, would lead to an increased prevalence of vitamin D deficiency compared to subjects treated with VLED. 971 individuals eligible for surgical, RYGB (n = 388), SG (n = 201), and medical treatment (n = 382), in routine care, were included consecutively between 2015 and 2017. A random population sample from the WHO-MONICA project was used as a reference, (n = 414). S-calcium, S-25(OH)D (vitamin D), and S-PTH (parathyroid hormone) were measured in all persons with obesity at baseline and two years after treatment (n = 713). Self-reported use of vitamin D and calcium supplementation was registered. Results Vitamin D deficiency (S-25(OH)D <25mmol/l) was found in 5.2% of the persons with obesity at baseline versus 1.7% of the general population (SMD>0.1). S-25(OH)D increased for all treatment groups but was higher in RYGB and SG (SMD>0.1, standardized mean difference). Thirteen subjects (1.8%) had vitamin D deficiency after obesity treatment. Conclusion Surgical intervention for obesity followed by vitamin D supplementation was not associated with a higher risk for vitamin D deficiency, irrespective of surgery type, compared to individuals on medical treatment. However, persons living with obesity seeking weight loss treatment are more likely to have deficient vitamin D levels compared to the general population.

- Context: Turner syndrome (TS) is the most common chromosomal aberration in women; it is the result of structural or numeric abnormalities in the X chromosome. Autoimmune hypothyroidism has been recognized as one of the more prominent disorders associated with TS.Objective: This work aimed to study the prevalence of autoimmune diseases in TS.Methods: A cross-sectional, longitudinal, 25-year follow-up study was conducted of patients from adult Turner centers at the University Hospitals, Sweden. During 1994 to 2020, a total of 503 women aged 16 to 71 years with TS were evaluated consecutively every fifth year according to national guidelines. A random population sample of women, n = 401, aged 25 to 44 years, from the World Health Organization Monitoring of Trends and Determinants for Cardiovascular Disease (MONICA) project served as controls. Serum thyrotropin, free thyroxine, vitamin B-12, antithyroid peroxidase (anti-TPO), and antitransglutaminase antibodies were measured.Results: Mean follow-up time (years) was 16 +/- 7 for patients and 13 +/- 1 for controls. From study start, the prevalence increased in TS for hypothyroidism 40% to 58%, vitamin B-12 deficiency 5% to 12%, celiac disease 4% to 7%, positive anti-TPO 26% to 41%, and antitransglutaminase antibodies 6% to 8% (P < .0001 vs controls). Type 1 diabetes and Addison disease were rare. The only interrelationship was between hypothyroidism and vitamin B-12 deficiency, both in TS and controls. No association between autoimmune disease and karyotype, antecedent growth hormone treatment, or ongoing estrogen hormone replacement, was seen in TS.Conclusion: In women with TS up to older than 80 years, more than half developed hypothyroidism, mainly autoimmune, during follow-up. Awareness of vitamin B-12 deficiency and celiac disease throughout life is also recommended in women with TS.

- Context: Patients with hypopituitarism of various etiologies have excess mortality. The mortality in patients with nonfunctioning pituitary adenoma (NFPA), regardless of pituitary function, is less well studied. Objective: Our aim was to investigate mortality in patients with NFPA and to examine whether age at diagnosis, gender, tumor treatments, or hormonal deficiencies influence the outcome. Design: NFPA patients were identified and followed up in nationwide health registries in Sweden, 1987-2011. The criteria for identification were tested and validated in a subpopulation of the patients. Patients: A total of 2795 unique patients with NFPA (1502 men, 1293 women) were identified and included in the study. Mean age at diagnosis was 58 years (men, 60 y; women, 56 y) and mean follow-up time was 7 years (range 0-25 y). Main Outcome Measures: Standardized mortality ratios (SMRs) and annual incidence rates were calculated using the Swedish population as reference and presented with 95% confidence intervals. Results: Annual incidence of NFPA was 20.3 (18.8-21.9) cases per 1 million inhabitants. During the observation period, 473 patients died against an expected 431, resulting in an SMR of 1.10 (1.00-1.20). Patients diagnosed at younger than 40 years of age had an increased SMR of 2.68 (1.23-5.09). The SMR for patients with hypopituitarism (n = 1500) was 1.06 (0.94-1.19), and for patients with diabetes insipidus (n = 145), it was 1.71 (1.07-2.58). The SMR was increased in women with NFPA (1.29; 1.11-1.48) but not in men (1.00; 0.88-1.12). Women, but not men, with a diagnosis of hypopituitarism and/or diabetes insipidus also had an increased mortality ratio. SMRs due to cerebrovascular (1.73; 1.34-2.19) and infectious diseases (2.08; 1.17-3.44) were increased, whereas the SMR for malignant tumors was decreased (0.76; 0.61-0.94). Conclusions: This nationwide study of patients with NFPA showed an overall excess mortality in women and in patients with a young age at diagnosis. Increased mortality was seen for cerebrovascular and infectious diseases.
