- In an analysis of 31,717 cancer cases and 26,136 cancer-free controls from 13 genome-wide association studies, we observed large chromosomal abnormalities in a subset of clones in DNA obtained from blood or buccal samples. We observed mosaic abnormalities, either aneuploidy or copy-neutral loss of heterozygosity, of >2 Mb in size in autosomes of 517 individuals (0.89%), with abnormal cell proportions of between 7% and 95%. In cancer-free individuals, frequency increased with age, from 0.23% under 50 years to 1.91% between 75 and 79 years (P = 4.8 × 10(-8)). Mosaic abnormalities were more frequent in individuals with solid tumors (0.97% versus 0.74% in cancer-free individuals; odds ratio (OR) = 1.25; P = 0.016), with stronger association with cases who had DNA collected before diagnosis or treatment (OR = 1.45; P = 0.0005). Detectable mosaicism was also more common in individuals for whom DNA was collected at least 1 year before diagnosis with leukemia compared to cancer-free individuals (OR = 35.4; P = 3.8 × 10(-11)). These findings underscore the time-dependent nature of somatic events in the etiology of cancer and potentially other late-onset diseases.

- Analyses of genome-wide association study (GWAS) data have revealed that detectable genetic mosaicism involving large (>2 Mb) structural autosomal alterations occurs in a fraction of individuals. We present results for a set of 24,849 genotyped individuals (total GWAS set II [TGSII]) in whom 341 large autosomal abnormalities were observed in 168 (0.68%) individuals. Merging data from the new TGSII set with data from two prior reports (the Gene-Environment Association Studies and the total GWAS set I) generated a large dataset of 127,179 individuals; we then conducted a meta-analysis to investigate the patterns of detectable autosomal mosaicism (n = 1,315 events in 925 [0.73%] individuals). Restricting to events >2 Mb in size, we observed an increase in event frequency as event size decreased. The combined results underscore that the rate of detectable mosaicism increases with age (p value = 5.5 x 3 10(-31)) and is higher in men (p value = 0.002) but lower in participants of African ancestry (p value = 0.003). In a subset of 47 individuals from whom serial samples were collected up to 6 years apart, complex changes were noted over time and showed an overall increase in the proportion of mosaic cells as age increased. Our large combined sample allowed for a unique ability to characterize detectable genetic mosaicism involving large structural events and strengthens the emerging evidence of non-random erosion of the genome in the aging population.

- OBJECTIVE: To study the expression, distribution, and function of thyroid-stimulating hormone receptor (TSHR) and thyroid hormone receptors (TR) alpha1, alpha2, and beta1 in human endometrium. DESIGN: Experimental clinical study. SETTING: University hospital. PATIENT(S): 31 fertile women. INTERVENTION(S): Endometrial biopsy samples obtained throughout the menstrual cycle. MAIN OUTCOME MEASURE(S): Real-time reverse transcriptase polymerase chain reaction, immunohistochemistry and Western blot to study the expression of TSHR, TRalpha1, TRalpha2, and TRbeta1 messenger RNA (mRNA) and proteins in human endometrium. RESULT(S): We found TSHR, TRalpha1, TRalpha2 and TRbeta1 mRNA and proteins expressed in human endometrium. Immunostaining for TSHR in the luminal epithelium and TRalpha1 and beta1 in the glandular and luminal epithelium increased statistically significantly on luteinizing hormone (LH) days 6 to 9, coinciding with appearance of pinopodes. Endometrial stromal and Ishikawa cells expressed mRNA for TSHR, TR, and iodothyronine deiodinases 1-3. After 48 hours, TSH significantly increased leukemia inhibitory factor (LIF) and LIF receptor (LIFR) messenger RNA (mRNA) in endometrial stromal cells, but decreased their expression in Ishikawa cells. Glucose transporter 1 mRNA was up-regulated by TSH in Ishikawa cells. We found that TSH statistically significantly increased secretion of free triiodothyronine (T(3)) and total thyroxin (T(4)) by Ishikawa cells compared with nonstimulated cells. CONCLUSION(S): Thyroid hormones are directly involved in endometrial physiology.

- Autoimmune polyglandular syndrome type I (APS I) is an autosomal recessive disorder characterized by a combination of autoimmune manifestations affecting endocrine and non-endocrine organs. APS I usually presents in childhood. The three most common manifestations are chronic mucocutaneous candidiasis, hypoparathyroidism and Addison's disease. At least two of these must be present to fulfill the diagnostic criteria of this syndrome. The spectrum of other associated diseases includes gonadal insufficiency, alopecia, vitiligo and chronic active hepatitis. APS I is caused by a mutation in the AIRE-gene (autoimmune regulator) located on chromosome 21. Analysis of specific autoantibodies against intracellular enzymes, particularly enzymes in the synthesis of steroids and neurotransmittors, can be used in the diagnosis of APS I and to predict different manifestations of the disease.

Tidskriftsartikel (refereegranskat)abstract
- Objectives Distribution of take-home naloxone is suggested to reduce opioid-related fatalities, but few studies have examined the effects on overdose deaths in the general population of an entire community. This study aimed to assess the effects on overdose deaths of a large-scale take-home naloxone programme starting in June 2018, using an observational design with a historic control period. Design From the national causes of death register, deaths diagnosed as X42 or Y12 (International Classification of Diseases, 10th revision, ICD-10) were registered as overdoses. Numbers of overdoses were calculated per 100 000 inhabitants in the general population, and controlled for data including only individuals with a prior substance use disorder in national patient registers, to focus on effects within the primary target population of the programme. The full intervention period (2019-2021) was compared with a historic control period (2013-2017). Setting Skåne county, Sweden. Participants General population. Interventions Large-scale take-home naloxone distribution to individuals at risk of overdose. Primary and secondary outcome measures Decrease in overdose deaths per 100 000 inhabitants, in total and within the population with substance use disorder diagnosis. Results Annual average number of overdose deaths decreased significantly from 3.9 to 2.8 per 100 000 inhabitants from the control period to the intervention period (a significant decrease in men, from 6.7 to 4.3, but not in women, from 1.2 to 1.3). Significant changes remained when examining only prior substance use disorder patients, and decreases in overdose deaths could not be attributed to a change in treatment needs for opioid use disorders in healthcare and social services. Conclusions The present study, involving 3 years of take-home naloxone distribution, demonstrated a decreased overdose mortality in the population, however, only in men. The findings call for further implementation of naloxone programmes, and for further studies of potential effects and barriers in women. Trial registration number NCT03570099.

Tidskriftsartikel (refereegranskat)abstract
- Background: Rheumatoid arthritis (RA) is a chronic, systemic, inflammatory joint disease, that influences patients’ health in different ways, including physical, social, emotional, and psychological aspects. The goal of rheumatology care is to achieve optimal health and personalised care and therefore, it is essential to understand what health means for patients in the early course of RA. The aim of this study was to describe the understanding of health among patients with early RA.Methods: The study had a descriptive qualitative design with a phenomenographic approach. Phenomenography is used to analyse, describe, and understand various ways people understand or experience a phenomenon, in this study, patients’ understandings of health. Individual semi-structured interviews were conducted with 31 patients (22 women and nine men, aged (38–80) with early RA, defined as a disease duration of < 1 year, and disease-modifying anti-rheumatic drugs (DMARDs) for 3–7 months. The phenomenographic analysis was conducted in 7 steps, and the outcome space presents the variation in understanding and the interrelation among categories. In accordance with the European Alliance of Associations for Rheumatology’s (EULAR) recommendations, a patient research partner participated in all phases of the study.Results: The analysis revealed four main descriptive categories: ‘Health as belonging’ was described as experiencing a sense of coherence. ‘Health as happiness’ was understood as feeling joy in everyday life. ‘Health as freedom’ was understood as feeling independent. ‘Health as empowerment’ was understood as feeling capable. Essential health aspects in early RA are comprised of a sense of coherence, joy, independence, and the capability to manage everyday life.Conclusions: This study revealed that patients’ perception of health in early RA encompasses various facets, including a sense of belonging, happiness, freedom, and empowerment. It highlighted that health is multifaceted and personal, emphasizing the importance of acknowledging this diversity in providing person-centred care. The findings can guide healthcare professionals to deepen patients’ participation in treatment goals, which may lead to better treatment adherence and health outcomes. © The Author(s) 2024.

- Purpose: To explore patients’ preferred treatment outcomes during their first two years with rheumatoid arthritis (RA). Patients and Methods: A qualitative, longitudinal, multicenter study with interviews at two time points was performed in Sweden. Individual interviews were conducted at time point 1 with 31 patients with RA, defined as disease duration of ≤1 year and treatment for 3–7 months. Seven focus group interviews and five individual interviews were conducted at time point 2 with 22 patients 12–20 months after treatment initiation. The interviews were analyzed using the Qualitative Analysis Guide of Leuven. A core category with four related concepts emerged. Results: The core finding of patient-preferred treatment outcomes was “mastering a new life situation”. Patients preferred to experience control of the disease by controlling the symptoms and by experiencing absence of disease. To experience autonomy by regaining former activity level, experiencing independence, and being empowered was another preferred outcome. Patients preferred to regain identity through being able to participate, experience well-being, and regain former self-image. To experience joy in everyday life through vitality and believing in the future was another preferred outcome. Patients’ preferences developed over time from the acute phase of controlling the symptoms and wanting to return to the life they lived prior to diagnosis, to a more preventive way of self-management and empower-ment to master the new life situation. Conclusion: The patients’ preferred treatment outcomes during the first two years with RA were to master their new life situation and changed from a preference to return to a life lived prior disease onset, to a preference of living with quality of life, despite RA. This study increases the understanding of patients’ preferred treatment outcomes in the early disease course and can be a foundation for tailoring interventions to be more person-centered and to improve long-term treatment outcomes. © 2020 Landgren et al.
