Background: This study assessed the cost-effectiveness of proton beam therapy (PBT) compared to conventional radiotherapy (CRT) for treating patients with brain tumors in Sweden. Methods: Data from a longitudinal non-randomized study performed between 2015 and 2020 was used, and included adult patients with brain tumors, followed during treatment and through a one-year follow-up. Clinical and demographic data were sourced from the longitudinal study and linked to Swedish national registers to get information on healthcare resource use. A cost-utility framework was used to evaluate the cost-effectiveness of PBT vs. CRT. Patients in PBT group (n = 310) were matched with patients in CRT group (n = 40) on relevant observables using propensity score matching with replacement. Costs were estimated from a healthcare perspective and included costs related to inpatient and specialized outpatient care, and prescribed medications. The health outcome was quality-adjusted life-years (QALYs), derived from the EORTC-QLQ-C30. Generalized linear models (GLM) and two-part models were used to estimate differences in costs and QALYs. Results: PBT yielded higher total costs, 14,639 US$, than CRT, 13,308 US$, with a difference of 1,372 US$ (95% CI, -4,914–7,659) over a 58 weeks' time horizon. Further, PBT resulted in non-significantly lower QALYs, 0.746 compared to CRT, 0.774, with a difference of -0.049 (95% CI, -0.195–0.097). The probability of PBT being cost-effective was < 30% at any willingness to pay. Conclusions: These results suggest that PBT cannot be considered a cost-effective treatment for brain tumours, compared to CRT. Trial registration: Not applicable. Novelty and Impact: This study informs on the cost-effectiveness of proton beam therapy (PBT) versus conventional radiotherapy (CRT) for patients with brain tumors in Sweden. Amidst global concerns regarding the cost-effectiveness of PBT, our investigation fills a notable gap by providing evidence from the Swedish healthcare landscape. Using real-world data, our study demonstrates the application of established health economic methodology to compare PBT and CRT for brain tumors, furthering research in this area.

Introduction/objectives: Primary health care visits post-discharge could potentially play an important role in efforts of reducing hospital readmission. Focusing on a single or a particular type of visit obscures nuances in types of primary care contacts over time and fails to quantify the intensity of primary health care visits during the follow-up period. The aim of this study was to explore associations between the number and type of primary health care visits post-discharge and the risk of hospital readmission within 30 days. Methods: A register-based closed cohort study. The study population of 6135 individuals were residents of Stockholm who were discharged home from any of the 3 geriatric inpatient departments, excluding those who were readmitted within the next 24 h. The dependent variable was hospital readmission within 30 days of discharge. The key independent variable was the number and type of primary health care visits in 30 days post-discharge. Cox-regression with time-varying covariates was employed for data analyses. Results: Approximately, 12% of the participants were readmitted to hospital within 30 days. There was no statistically significant association between number of primary care visits post-discharge and readmission (HR 1.00; 95% CI 1.00-1.01). Compared to no primary health care visit, no statistically significant association were found for administrative care related visits (HR 0.33, 95%CI 0.08-1.33), clinic visits (HR 0.93, 95%CI 0.71-1.21), home visits (HR 1.03, 95%CI 0.84-1.27), or team visits (HR 0.76, 95%CI 0.54-1.07). Conclusions: There were no associations between primary health care visits post-discharge and hospital readmission after geriatric inpatient care. Further studies using survey or qualitative approaches can provide insights into the factors that are relevant to post-discharge care but are unavailable in this type of register data studies.

Summary: In this large population-based matched cohort study, patients with primary aldosteronism were at increased risk of hip fracture, particularly subgroups traditionally considered at higher risk of osteoporosis such as women, patients older than 56 years at diagnosis, patients with established cardiovascular disease at diagnosis, and patients treated with MRA. Purpose: Previous studies suggest that primary aldosteronism (PA) is associated with dysregulated bone homeostasis. The aim of this study was to evaluate the incidence of hip fractures in patients with PA. Methods: We studied a nationwide cohort of 2419 patients with PA (1997–2019) and 24 187 age and sex matched controls from the general population. Hip fractures were identified by ICD codes in the Swedish National Patient Register. We estimated hazard ratios (HRs) for incident hip fractures, adjusted for prior fractures, socioeconomic factors, diabetes, osteoporosis, hyperparathyroidism, and cardiovascular disease (CVD). Pairwise subgroup comparisons were performed by age (18–56 and > 56 years), sex, CVD at baseline, and treatment for PA. Results: During a mean follow up of 8 ± 5 years, 64 (2.6%) patients had a hip fracture after being diagnosed with PA, compared to 401 (1.7%) controls. After adjustments, PA was associated with a 55% increased risk of hip fracture compared to controls (HR 1.55 [1.18–2.03]). HRs were increased in women (HR 1.76 [95% CI 1.24–2.52]), patients aged > 56 years (HR 1.62 [95% CI 1.21–2.17]), and patients with CVD at diagnosis (HR 2.15 [95% CI 1.37–3.37]). PA patients treated with adrenalectomy did not have higher risk than controls (HR 0.84 [95% CI 0.35–2.0]), while patients treated with mineralocorticoid receptor antagonists (MRA) retained a greater risk (HR 1.84 [95% CI 1.20–2.83]). Conclusion: PA is associated with increased hip fracture risk, especially in women, patients diagnosed after the age of 56 years and patients with established CVD at diagnosis. Also, patients treated with MRA seem to have an increased risk of hip fractures, while adrenalectomy may be protective. [ABSTRACT FROM AUTHOR]

Background: To prevent the spread of SARS‐CoV‐2, hospitals around the world adopted protocols that, in varying ways, resulted in the exclusion of partners from hospital postnatal care wards. The objective of this study was to examine the effect this exclusion had on partners' satisfaction with postnatal care. Methods: An online survey (the Swedish Pregnancy Panel) including free‐text comments was conducted before and during the first wave of the COVID‐19 pandemic; partners of pregnant women were recruited at an early ultrasound appointment and followed until 2 months after childbirth. Data were linked to the Swedish Pregnancy Register. Results: The survey was completed by 524 partners of women who gave birth during the pandemic and 203 partners of women who gave birth before. Partners' satisfaction with hospital postnatal care dropped 29.8 percent (−0.94 OLS, 95% CI = −1.17 to −0.72). The drop was largest for partners of first‐time mothers (−1.40 OLS, 95% CI = −1.69 to −1.11), but unrelated to clinical outcomes such as mode of birth and most social backgrounds, except higher income. The qualitative analysis showed that partners (1) felt excluded as partners and parents, (2) thought the strain on staff led to deficiencies in the care provided, and (3) perceived the decision about partner restrictions as illogical. Conclusions: The exclusion of partners from the hospital postnatal wards clearly impaired satisfaction with care, and partners of first‐time mothers were particularly affected. Planning for future restrictions on partners from hospital wards should factor in these consequences. [ABSTRACT FROM AUTHOR]

Objective: To investigate the prevalence of diabetes retinopathy and evaluate the factors influencing its occurrence both at the onset of type 2 diabetes (T2D) and three years into its duration. Design: Retrospective population-based study. Setting: Data was retrieved from Regional Healthcare Information Platform in Region Halland 2016–2020. Subjects: Patients 35-75 years old in Region Halland receiving first-time diabetes diagnosis according to ICD-code E11-14 in 2016–17. The total cohort consisted of 1659 patients. Main outcome measures: The main outcome measure of the study was the occurrence of diabetes retinopathy at onset and within three years from the diabetes diagnosis. Multivariate logistic regression analysis was conducted for diabetes retinopathy at onset and within three years, adjusted for age, gender, comorbidities, levels of HbA1c, cholesterol, kidney functional and blood pressure. Results: At onset, there were 12% with diabetes retinopathy and after three years, 32% of the patients had developed diabetes retinopathy. In the study cohort, 71 of patients who were examined with fundus photography within three years after onset, and 8% had had dietary recommendation without pharmacotherapy. High HbA1c levels, blood pressure values and impaired renal function already at onset were associated with development of diabetes retinopathy at onset and this association persisted after three years. The odds ratio for diabetes retinopathy was increased adjusted for HbA1c elevations, renal impairment, and increased blood pressure at index and when adjusted for these variables three years from index. Conclusion: These findings indicate that the risk of developing diabetes retinopathy is present early on at onset and within the first three years of diabetes diagnosis. This highlights the importance of promptly regulating glucose- and blood-pressure levels and follow up kidney dysfunction to mitigate the risk of diabetes retinopathy. KEY POINTS: Among patients with type 2 diabetes, 12% had developed diabetes retinopathy already at onset. Among patients with type 2 diabetes, one-third had developed diabetes retinopathy after three years from onset. The presence of diabetes retinopathy already at diabetes onset, was associated with elevated HbA1c levels, renal impairment and elevated blood pressure. Diabetes retinopathy three years after the onset of the disease, was associated with increased HbA1c levels, high blood pressure, and renal dysfunction. [ABSTRACT FROM AUTHOR]

Objectives: To investigate whether intensified cooperation between general practitioner (GP), care manager and rehabilitation coordinator (RC) for patients sick-listed for stress-related mental disorder, combined with a person-centred dialogue meeting with employer, could reduce sick-leave days compared with usual care manager contact. Design: Pragmatic cluster-randomised controlled trial, randomisation at primary care centre (PCC) level. Setting: PCCs in Region Västra Götaland, Sweden, with care manager organisation. Participants: Of 30 invited PCCs, 28 (93%) accepted the invitation and recruited 258 patients newly sick-listed due to stress-related mental disorder (n = 142 intervention, n = 116 control PCCs). Intervention: Cooperation between GP, care manager and rehabilitation coordinator from start of illness notification plus a person-centred dialogue meeting between patient and employer within 3 months. Regular contact with care manager was continued at the control PCCs. Main outcome measures: 12-months net and gross number of sick-leave days. Secondary outcomes: Symptoms of stress, depression, anxiety; work ability and health related quality of life (EQ-5D) over 12 months. Results: There were no significant differences between intervention and control groups after 12 months: days on sick-leave (12-months net sick-leave days, intervention, mean = 110.7 days (95% confidence interval (CI) 82.6 − 138.8); control, mean = 99.1 days (95% CI 73.9 − 124.3)), stress, depression, or anxiety symptoms, work ability or EQ-5D. There were no significant differences between intervention and control groups concerning proportion on sick-leave after 3, 6, 12 months. At 3 months 64.8% were on sick-leave in intervention group vs 54.3% in control group; 6 months 38% vs 32.8%, and12 months 16.9% vs 15.5%. Conclusion: Increased cooperation at the PCC between GP, care manager and RC for stress-related mental disorder coupled with an early workplace contact in the form of a person-centred dialogue meeting does not reduce days of sick-leave or speed up rehabilitation.

Purpose: Return-to-work coordinators (RTWCs) give people on sick leave individualized support and coordinate between different stakeholders, including physicians. The aim of this study was to explore physicians' experience of RTWCs and investigate factors that influence how much physicians collaborate with RTWCs, or refer patients to them, in primary, orthopaedic, and psychiatric care clinics. Materials and methods: Of the 1229 physicians responding to a questionnaire, 629 physicians who had access to a RTWC in their clinic answered to questions about collaborating with RTWCs. Results: Among physicians who had access to a RTWC, 29.0% collaborated with a RTWC at least once a week. Physicians with a more favourable experience of RTWCs reported more frequent collaboration (adjusted OR 2.92, 95% CI 2.06–4.15). Physicians also collaborated more often with RTWCs if they reported to often deal with problematic sick-leave cases, patients with multiple diagnoses affecting work ability, and conflicts with patients over sickness certification. Conclusions: Physicians who had more problematic sick-leave cases to handle and a favourable experience of RTWCs, also reported collaborating more often with RTWCs. The results indicate that RTWCs' facilitation of contacts with RTW stakeholders and improvements in the sickness certification process may be of importance for physicians. IMPLICATIONS FOR REHABILITATION: This study of physicians' experience of collaborating with return-to-work coordinators (RTWCs) observes that physicians reported more collaboration with or referrals to coordinators if they had a favourable experience of coordinators. The results indicate that physicians report more collaboration with or referrals to RTWCs if they had more problematic sick-leave cases to handle in the clinic. These findings imply that it might be possible to increase the collaboration between physicians and RTWCs in clinical settings by managing factors of importance. [ABSTRACT FROM AUTHOR]

Background: Venous thromboembolism (VTE) has a high mortality rate and can be the first manifestation of cancer. We investigated the incidence of cancer after first-ever VTE and the association between VTE and all-cause mortality. Methods: A Swedish cohort study that included 105,997 participants without previous cancer who underwent a health examination from 1985–2014 was conducted. Manually validated first-ever VTE events, incident cancer according to the Swedish cancer registry, and mortality were registered. Participants were followed until September 5, 2014. Results: The mean age at inclusion was 46.2 years, and 50.3% of participants were female. We identified 1303 persons in the cohort with a VTE and no previous cancer. Among these, 179 (13.7%) were diagnosed with cancer after the VTE event, resulting in a cancer incidence of 26.4 (95% CI 22.8–30.6) cases per 1000 person-years. The incidence was highest during the first 6 months after the VTE. In the study population, VTE was associated with an increased risk of cancer (HR 1.95 [95% CI 1.67–2.29] in a multivariable model). VTE was also associated with an increased risk of death (HR 6.30 [95% CI 5.82–6.81]) in a multivariable model). There was an interaction between sex and VTE in relation to both risk of cancer and mortality, with a stronger association in women. Conclusions: The incidence of cancer is high after first-ever VTE, especially close to the VTE event. VTE seems to be a stronger risk marker in women than in men for both cancer and death.

Evidence of inequality in the utilisation of mental health care (MHC) by adolescents in Nordic countries is mixed. This study aims to investigate if there are socioeconomic differences in the utilisation of MHC, while accounting for adolescents' mental health status. We analysed a cohort of 3517 adolescents, followed from 7 to 9th grade (ages 13–16), to examine the association between parental socioeconomic position (SEP: education and disposable income), adolescents' estimated needs, and the utilisation of MHC (defined as visits to secondary psychiatric care or receipt of psychotropic medication). Logistic and negative binomial regression models, with mental health status as moderator, were used to predict utilisation during each grade. Lower SEP predicted higher odds of utilising MHC in adolescents with no/mild symptoms (e.g., odds ratio, OR = 1.33, 95% CI 1.04–1.72, lower vs highest education), but not in those with moderate-to-severe symptoms (estimates close to one and non-significant). This pattern was largely explained by treatment of attention deficit hyperactivity disorder/autism spectrum disorders (ADHD/ASD) in boys. For girls with severe symptoms, lower SEP predicted reduced odds of utilising MHC for other mental disorders (OR = 0.48, 95% CI 0.25–0.92, lower education), and fewer outpatient visits when in contact with such care, although non-significant (incidence rate ratio, IRR = 0.51, 95% CI 0.25–1.05, lowest vs highest income). Our findings suggest a more equitable use of MHC for treating ADHD/ASD, but not other mental disorders such as depression and anxiety, particularly among girls. [ABSTRACT FROM AUTHOR]

Cervical cancer screening (CCS) is an important public health measure for early detection of cervical cancer and prevents a large proportion of cervical cancer deaths. However, participation in CCS is relatively low and varies substantially by country and socio-economic position. This study aimed to provide up-to-date participation rates and estimates on educational inequalities in CCS participation in 24 European countries with population-based CCS programmes. This was a cross-sectional study. Using data from the European Health Interview Survey (EHIS) conducted in 2019, 80,479 women aged 25–64 years were included in the analyses. First, standardized participation rates and standardized participation rates by educational attainment were calculated for all 24 countries based on each country-specific screening programme organization. Second, a series of generalized logistic models was applied to assess the effect of education on CCS participation. Screening participation rates ranged from 34.1% among low-educated women in Romania to 97.1% among high-educated women in Finland. We observed that lower-educated women were less likely to attend CCS than their higher-educated counterparts. Largest educational gaps were found in Sweden (odds ratio [OR] = 6.36, 95% confidence interval [CI] = 3.89–10.35) and Poland (odds ratio = 5.80, 95% CI = 4.34–7.75). Population-based screening initiatives have successfully reduced participation differences between women with medium and high educational attainment in some countries; however, persistent disparities still exist between women with low and high levels of education. There is an urgent need to increase participation rates of CCS, especially among lower-educated women. [ABSTRACT FROM AUTHOR]

Background Some studies have reported an increase in suicides after the start of daylight saving time (DST), but the evidence is mixed and more research about proposed mechanisms (disrupted sleep, changing light exposure) is needed. Methods In our preregistered study, we analyzed change in suicide rates in the 2 weeks before/after DST, based on data between 1980 and 2022 from Austria, Switzerland and Sweden, using Poisson regression models and changepoint analyses. To explore the impact of disrupted sleep, we repeated the analysis for retired people who are likely less bound to DST, and for younger people. To explore the effect of changed daylight exposure, we repeated the analysis for northern and southern regions because twilight and daylight exposure varies by latitude. Results Suicide rates did not significantly increase after the start of DST (adjusted incidence rate ratio IRR = 0.98, 95% CI 0.91–1.06, P  = 0.66, n  = 13 362 suicides) or after DST ended (adjusted IRR = 0.99, 95% CI 0.91–1.07, P  = 0.76, n  = 12 319 suicides). There were no statistically significant findings among younger or older subgroups and also not in Sweden and Austria/Switzerland. No changepoints were detected. Conclusions There were no significant changes in suicide rates associated with DST and no clear evidence to support proposed mechanisms (light exposure, disruption of sleep). Our study is one of the largest and was adequately powered. Nonetheless, even larger studies to detect smaller effects could be important to inform the debate about harms and benefits of DST.

Background: Generalized joint hypermobility as a characteristic feature of Ehlers–Danlos syndromes (EDS) is among the factors contributing to temporomandibular disorders (TMD). Objective: To evaluate the prevalence of TMD symptoms and their risk factors among women born in Sweden or Finland who were 27‐ to 78‐year‐olds with diagnosed hypermobile EDS (hEDS). Methods: A cohort of women with confirmed hEDS (n = 185) was constructed from the members of the National EDS Associations in both countries. Based on questionnaire data, frequency of independent variables in terms of socio‐demographic, general health and oral health‐related factors, comorbid symptoms and psychological distress for self‐reported TMD symptoms as the dependent variables, were calculated first. Prevalence ratios (PR) and their 95% confidence interval (95% CI) were estimated for the association between independent and dependent variables. Results: Nearly all participants reported TMD symptoms (98%) with TMD pain (95%), TMJ clicking (90%) and jaw fatigue (80%) as the most common symptoms and TMJ crepitation (63%) and luxation (44%) as the least common symptoms. Risk factors for TMD among 27‐ to 50‐year‐olds participants were Finland as a country of birth, living alone and self‐reported worst pain in the body (not the joints). The respective risk factors among the 51‐ to 78‐year‐olds were Finland as a country of birth, family history of EDS, tinnitus and regularly taking contraceptives. Conclusions: Among adult women with confirmed hEDS, socio‐demographic and health‐related factors and comorbid symptoms were significantly associated with TMD but with differences regarding age group. Therefore, management of TMD requires a multidisciplinary approach among the affected. [ABSTRACT FROM AUTHOR]

Aims: There is substantial evidence that previous working conditions influence post-retirement health, yet little is known about previous working conditions' association with old-age dependency. We examined job strain, hazardous and physical demands across working life, in relation to the risk of entering old-age dependency of care. Methods: Individually linked nationwide Swedish registers were used to identify people aged 70+ who were not receiving long-term care (residential care or homecare) at baseline (January 2014). Register information on job titles between the years 1970 and 2010 was linked with a job exposure matrix of working conditions. Random effects growth curve models were used to calculate intra-individual trajectories of working conditions. Cox regression models with age as the timescale (adjusted for living situation, educational attainment, country of birth, and sex) were conducted to estimate hazard ratios for entering old-age dependency during the 24 months of follow-up (n = 931,819). Results: Having initial adverse working conditions followed by an accumulation throughout working life encompassed the highest risk of entering old-age dependency across the categories (job strain: HR 1.23, 95% CI 1.19–1.27; physical demands: HR 1.36, 95% CI 1.31–1.40, and hazardous work: HR 1.35, 95% CI 1.30–1.40). Initially high physical demands or hazardous work followed by a stable trajectory, or initially low-level physical demand or hazardous work followed by an accumulation throughout working life also encompassed a higher risk of dependency. Conclusions: A history of adverse working conditions increased the risk of old-age dependency. Reducing the accumulation of adverse working conditions across the working life may contribute to postponing old-age dependency. [ABSTRACT FROM AUTHOR]

Aims: This study aimed to examine the association between gender composition in the workplace and sickness absence days during a one-year period. Methods: The study population was drawn from the Northern Swedish Cohort (wave 3; 2007) by Statistics Sweden and consisted of all participants belonging to a specific workplace (n =837) as well as all co-workers at the workplace of the participants (n =132,464; 67,839 women and 64,625 men). Exposure was the gender composition of the workplace, and outcome was cumulative sickness absence days (⩾ 90 days or not) during 2007, provided through a link to the Database for Health Insurance and Labour Marked Studies of Statistics Sweden. Covariates were gender, age, educational level and branch of industry from the same data source. We performed descriptive analyses and multivariable regression analyses. Results: Workers in extremely female-dominated workplaces had a significantly higher risk of cumulative sickness absence days (⩾90 days) compared with gender-equal workplaces (fully adjusted odds ratio (OR)=1.27; 95% confidence interval (CI) 1.09–1.48), whereas those working in extremely and moderately male-dominated workplaces had a significantly lower sickness absence risk (OR=0.62 and 0.66, respectively). Stratified by gender, the higher absence risk at female-dominated workplaces was fully explained by variation in branches of industry. Women working in extremely male-dominated workplaces had a significantly lower absence risk (OR=0.75), as did men working in moderately male-dominated workplaces (OR=0.78). Conclusions: Workplaces dominated by women had a significantly higher risk of days lost to sickness absence compared to gender-equal workplaces. Stratified by gender, this higher risk was explained by branch of industry. [ABSTRACT FROM AUTHOR]

Background: Operative treatment is widely used for acute proximal hamstring avulsions, but its effectiveness compared with that of nonoperative treatment has not been shown in randomized trials. Methods: In this noninferiority trial at 10 centers in Sweden and Norway, we enrolled patients 30 to 70 years of age with a proximal hamstring avulsion in a randomized trial and a parallel observational cohort. Treatments were operative reinsertion of the tendons or nonoperative management. The primary end point was the Perth Hamstring Assessment Tool (PHAT) at 2 years of follow-up. Secondary outcomes included scores on the Lower Extremity Functional Scale (LEFS). Results: A total of 119 patients were enrolled in the randomized trial and 97 patients in the observational cohort. In the per-protocol analysis of the randomized trial, the mean (±standard deviation) PHAT scores were 79.9±19.5 and 78.5±19.4 in the operative and nonoperative groups, respectively (PHAT scores range from 0 to 100, with higher scores indicating higher function). The prespecified noninferiority limit of 10 points was not crossed (mean difference, -1.2; 95% confidence interval [CI], -8.6 to 6.2; P=0.009 for noninferiority). Analyses of secondary outcomes, including a mean difference in the LEFS score of -1.6 (95% CI, -5.2 to 2.0), aligned with the primary outcome. The observed numbers of adverse events in the randomized trial were nine in the operative group versus three in the nonoperative group (odds ratio, 0.3; 95% CI, 0.1 to 1.2). In the analysis of the observational cohort, the mean PHAT score difference between the nonoperative and operative treatment groups was -2.6 (95% CI, -9.9 to 4.6). Conclusions: In patients 30 to 70 years of age with proximal hamstring avulsions, nonoperative treatment was noninferior to operative treatment.

Background: Lower respiratory tract infections (LRTIs) have an immediate significant impact on morbidity and mortality among older adults. However, the impact following the infectious period of LRTI remains understudied. We aimed to assess the short- to long-term impact of LRTIs on hospitalization, mortality, and healthcare utilization in older adults. Methods: Data from the Swedish National Study of Aging and Care in Kungsholmen (SNAC-K) was analyzed, with data from 2001 to 2019 for mortality and 2001–2016 for healthcare utilization. LRTI-exposed participants were identified and matched with LRTI-nonexposed based on sociodemographics, lifestyle factors, and functional and clinical characteristics. Statistical models evaluated post-LRTI hospitalization risk, days of inpatient hospital admissions, healthcare visits, and mortality. Results: 567 LRTIs-exposed participants during the study period and were matched with 1.701 unexposed individuals. LRTI-exposed individuals exhibited increased risk of hospitalization at 1-year (HR 2.14, CI 1.74, 2.63), 3-years (HR 1.74, CI 1.46, 2.07), and 5-years (HR 1.59, CI 1.33, 1.89). They also experienced longer post-LRTI hospital stays (IRR 1.40, CI 1.18, 1.66), more healthcare visits (IRR 1.47, CI 1.26, 1.71), specialist-care visits (IRR 1.46, CI 1.24, 1.73), and hospital admissions (IRR 1.57, CI 1.34, 1.83) compared to nonexposed participants over 16-years of potential follow-up. Additionally, the 19-year risk of mortality was higher among LRTI-exposed participants (HR 1.45, CI 1.24, 1.70). Men exhibited stronger associations with these risks compared to women. Conclusions: LRTIs pose both short- and long-term risks for older adults, including increased risks of mortality, hospitalization, and healthcare visits that transpire beyond the acute infection period, although these effects diminish over time. Men exhibit higher risks across these outcomes compared to women. Given the potential preventability of LRTIs, further public health measures to mitigate infection risk are warranted.

Background: Short- and midterm evaluations of arthroscopic meniscal surgery have shown little or no effect in favor of surgery, although long-term effects, including radiographic changes, are unknown. Purpose: To compare the 10-year outcomes in middle-aged patients with meniscal symptoms between a group that received an exercise program alone and a group that received knee arthroscopy in addition to the exercise program with respect to the prevalence of radiographic and symptomatic osteoarthritis (OA), patient-reported outcomes, and clinical status. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Of 179 eligible patients aged 45 to 64 years, 150 were randomized to undergo either 3 months of exercise therapy (nonsurgery group) or knee arthroscopy in addition to the exercise therapy (surgery group). Surgery usually consisted of partial meniscectomy (n = 56) or diagnostic arthroscopy (n = 8). Radiographs were assessed according to the Kellgren-Lawrence score at the baseline and 5- and 10-year follow-ups. Patient-reported outcome measures were reported at the baseline and 1-, 3-, 5-, and 10-year follow-ups. Clinical status was assessed at a 10-year follow-up. The primary outcomes were radiographic OA and changes in the Knee injury and Osteoarthritis Outcome Score Pain subscale (KOOSPAIN) from the baseline to the 10-year follow-up. The primary analysis was performed using the intention-to-treat approach. Results: At the time of the 10-year follow-up, eight patients had died, leaving 142 eligible patients. Radiographic OA was assessed for 95 patients (67%), questionnaires were answered by 110 (77%), and the clinical status was evaluated for 95 (67%). Radiographic OA was present in 67% of the patients in each group (P ≥.999); symptomatic OA was present in 47% of the nonsurgery group and 57% of the surgery group (P =.301). There were no differences between groups regarding changes from baseline to 10 years in any of the KOOS subscales. Conclusion: Knee arthroscopic surgery, in most cases consisting of partial meniscectomy or diagnostic arthroscopy, in addition to exercise therapy in middle-aged patients with meniscal symptoms, did not increase the rates of radiographic or symptomatic OA and resulted in similar patient-reported outcomes at the 10-year follow-up compared with exercise therapy alone. Considering the short-term benefit and no long-term harm from knee arthroscopic surgery, the treatment may be recommended when first-line treatment—including exercise therapy for ≥3 months—does not relieve patient's symptoms.

Background: Sickness absence has been linked to short and long, as well as poor, sleep in a few studies. Such studies have started from a baseline measurement and followed up on subsequent sickness absence. In the present study, however, we focused on the change in biennial reports of sickness absence and sleep measures (using work-related variables as possible modifiers). We also searched for an interaction between predictors and gender since women report more sleep problems. Methods: A total of 5377 individuals (random sample from the Swedish working population) participated across five biennial points of measurement. Data were analyzed using mixed-model logistic regression. Results: The multivariable analysis of variation across the five time points showed that the significant sleep-related predictors of sickness absence (at least one occurrence during the preceding year) were sleep duration during days off (OR = 1.16, 95% Cl = 1.08;1.24) and sleep problems (OR = 1.42, 95% CI = 1.33;1.51). These also remained significant after the addition of psychosocial work factors. Sensitivity analyses indicated that a 9 h sleep duration during days off may represent a critical level in terms of increased sickness absence and that late rising contributed to the association between sickness absence and long sleep duration during days off. Women reported a higher sickness absence than men (OR = 2.16, 95% CI = 1.74;2.68) and had a higher probability of sickness absence for long sleep during days off and during the workweek than men. Conclusions: It was concluded that increases in sleep problems and sleep duration during days off are longitudinally associated with changes in sickness absence and that women have a closer link between the two. This suggests that treatment for sleep problems may reduce the risk of sickness absence. [ABSTRACT FROM AUTHOR]

To investigate whether the association between depression and inflammatory joint disease (IJD; rheumatoid arthritis [RA], psoriatic arthritis [PsA], ankylosing spondylitis/spondyloarthropathies [AS], and juvenile idiopathic arthritis [JIA]) is affected by the severity or treatment-resistance of depression. Parallel cohort studies and case-control studies among 600,404 patients with a depressive episode identified in Swedish nationwide administrative registers. Prospective and retrospective risk for IJD in patients with depression was compared to matched population comparators, and the same associations were investigated in severe or treatment-resistant depression. Analyses were adjusted for comorbidities and sociodemographic covariates. Patients with depression had an increased risk for later IJD compared to population comparators (adjusted hazard ratio (aHR) for any IJD 1.34 [95% CI 1.30–1.39]; for RA 1.27 [1.15–1.41]; PsA 1.45 [1.29–1.63]; AS 1.32 [1.15–1.52]). In case-control studies, patients with depression more frequently had a history of IJD compared to population controls (adjusted odds ratio (aOR) for any IJD 1.43 [1.37–1.50]; RA 1.39 [1.29–1.49]; PsA 1.59 [1.46–1.73]; AS 1.49 [1.36–1.64]; JIA 1.52 [1.35–1.71]). These associations were not significantly different for severe depression or TRD. IJD and depression are bidirectionally associated, but this association does not seem to be influenced by the severity or treatment resistance of depression. [ABSTRACT FROM AUTHOR]

Aims: We estimated the prevalence of substance use disorders (SUDs) in the Norwegian, Danish and Swedish prison populations and compared the prevalence of SUDs in the national prison populations with country‐specific general population prevalence rates. Design: A multi‐national cohort study using data from the National Prison Registries linked to the National Patient Registries in Norway, Denmark and Sweden. Setting and participants: We used data from the PriSUD‐Nordic study, including national prison populations aged 19 years and older in Norway (2010–19), Denmark (2010–18) and Sweden (2010–13). A total of 119 507 Individuals (108 971 men and 10 536 women) contributing to 191 549 incarcerations were included in the study (Norway: 45432 men; 5429 women, Denmark: 42 162 men; 3370 women, Sweden: 21 377 men; 1737 women). Measurement: We calculated a study prevalence and prevalence at entry to prison for all types of SUDs before imprisonment each consecutive year of observation in each prison population. We also extracted country‐specific 1‐year prevalence rates from the Global Burden of Diseases database to calculate comparative national prevalence ratios. Findings The study prevalence of any SUD was approximately 40% [Norway: 44.0%, 95% confidence interval (CI) = 43.6–44.5%; Denmark: 39.9%, CI = 39.5–40.4%; Sweden: 39.1%, CI = 38.4–39.7%] in all three countries. Women had a significantly higher study prevalence of any SUD compared with men (Norway: 55.8 versus 42.6%, P < 0.001; Denmark 43.1 versus 39.7%, P = 0.004; Sweden: 51.7 versus 38.0%, P < 0.001). Prevalence estimates were higher for SUDs among people in prison than in the general population. We observed an increasing proportion of people with SUDs entering prison in Norway (P = 0.003), while the proportion was more stable in Denmark and Sweden. Conclusions: Substance use disorders (SUDs) appear to be highly prevalent among the Scandinavian prison populations compared with the general population, especially among women. In Norway, there was a relative increase in SUDs from 2010 to 2019. [ABSTRACT FROM AUTHOR]

Background: Sex differences in stroke are well documented, with females being older at onset, with more severe strokes and worse outcomes than males. Females receive less comprehensive stroke unit treatment. Similarly, older individuals receive poorer quality care than younger ones. There is limited research on sex differences in factors that impact 3‐month poststroke functional outcome in people older than 80 years. Methods: This register‐based and cross‐sectional study analyzed data from two stroke quality registers in Sweden from 2014 through 2019. The study included patients aged ≥80 with a diagnosis of ischemic or hemorrhagic stroke. Sociodemographic features, prestroke condition, stroke severity on admission (National Institutes of Health Stroke Scale [NIHSS]), stroke unit care, rehabilitation plans, and 3‐month poststroke functional outcome measured with the modified Rankin Scale were analyzed. Ordinal regression analyses stratified by sex were conducted to assess sex differences in factors that impact poststroke functional outcome 3 months after the stroke. Results: A total of 2245 patients were studied with the majority (59.2%) being females. Females experienced more severe strokes (NIHSS median 4 vs. 3, p = 0.01) and were older at stroke onset than males (87.0 vs. 85.4, p < 0.001). Females were also less independent prestroke (69.9% vs. 77.4%, p < 0.001) and a higher proportion of females lived alone (78.2% vs. 44.2%, p < 0.001). Males received intravenous thrombolysis more often than females (16.3% vs. 12.0%, p = 0.005). Regarding 3‐month functional outcome, males benefited more from thrombolysis (odds ratio [OR] 0.52, 95% confidence interval [CI] 0.30–0.83), whereas females benefited more from thrombectomy (OR 0.40, 95% CI 0.20–0.71). Conclusion: Stroke care should be adapted to sex disparities in older individuals, while clinicians should be aware of these sex disparities. Further research could clarify the mechanisms behind these disparities and lead to a more personalized approach to stroke care of the older population. [ABSTRACT FROM AUTHOR]

Objective Patients with RA treated with Janus kinase inhibitors (JAKis) are at increased risk of herpes zoster (HZ). The objective of this study was to investigate the serological immunogenicity and safety of the HZ subunit (HZ/su) vaccine in RA patients treated with JAKi, for which little is known. Methods RA patients treated with JAKi (n  = 82) at the Department of Rheumatology, Skåne University Hospital, Lund and Malmö, Sweden, and healthy controls (n  = 51) received two doses of the HZ/su vaccine (Shingrix). Vaccine-specific antibody responses were analysed using indirect ELISA. Post-vaccination antibody levels were compared between patients and controls using analysis of covariance. Potential predictors for vaccine response were investigated using a multivariable linear regression analysis. Self-reported adverse events (AEs) and changes in RA disease activity were analysed. Results Following vaccination, vaccine-specific antibody levels increased significantly in both patients and controls (P  < 0.0001). A total of 80.5% of patients and 98.0% of controls achieved a ≥4-fold increase in antibody levels. Post-vaccination antibody levels were lower in patients than controls [ratio 0.44 (95% CI 0.31, 0.63)] and lower in patients receiving JAKi + methotrexate than JAKi monotherapy [ratio 0.43 (95% CI 0.24, 0.79)]. AEs, mostly mild/moderate, were common. One patient developed HZ and six patients (6.5%) had increased RA disease activity following vaccination. Conclusion The HZ/su vaccine was serologically immunogenic in most RA patients treated with JAKi. Moreover, the vaccine had an acceptable safety profile. These results support recommendations for use of the HZ/su vaccine in this vulnerable population. Trial registration ClinicalTrials.gov (https://clinicaltrials.gov), NCT03886038.

Background: There is still debate regarding the association between arthrometric knee laxity measurements and subjective knee outcome and revision surgery after primary anterior cruciate ligament reconstruction (ACLR). Purpose: To assess whether arthrometric knee laxity (measured with the KT-1000 arthrometer) 6 months after primary ACLR was associated with the 1-, 2-, and 5-year subjective knee outcomes or revision ACLR at a 5-year follow-up. Study Design: Cohort study, Level of evidence 3. Methods: Patients who underwent primary ACLR with a hamstring tendon autograft at the authors' institution between January 1, 2005, and December 31, 2017, with no concomitant ligamentous injuries, were identified. Anterior knee laxity (KT-1000 arthrometer, 134 N) was assessed 6 months postoperatively. The Knee injury and Osteoarthritis Outcome Score (KOOS) was collected preoperatively and 1, 2, and 5 years postoperatively. Patients who underwent revision ACLR at any institution in the country within 5 years of primary surgery were identified through the Swedish National Knee Ligament Registry. Results: A total of 4697 patients (54.3% male) with available KT-1000 arthrometer measurements were included (normal: side-to-side [STS] ≤2 mm, 3015 [64.2%]; nearly normal: STS 3-5 mm, 1446 [30.8%]; abnormal: STS >5 mm, 236 [5.0%]). The only significant difference in subjective knee outcome between the groups was for the KOOS Symptoms subscale at the 1-year follow-up (STS ≤2 mm, 79.9 ± 16.2; STS 3-5 mm, 82.5 ± 14.8; STS >5 mm, 85.1 ± 14.2; P <.001). No other significant differences between the groups were found preoperatively or at 1, 2, or 5 years postoperatively for any of the KOOS subscales. The hazard for revision ACLR within 5 years of the primary surgery was significantly higher for the groups with an STS of 3 to 5 mm (6.6%; 95/1446) (hazard ratio [HR], 1.42; 95% CI, 1.07-1.87; P =.01) and an STS >5 mm (11.4%; 27/236) (HR, 2.61; 95% CI, 1.69-4.03; P <.001) compared with the group with an STS ≤2 mm (3.8%; 116/3015). Conclusion: A high grade of postoperative knee laxity (STS 3-5 mm and STS >5 mm) 6 months after primary ACLR was associated with an increased hazard of revision ACLR within 5 years, but it was not associated with an inferior subjective knee outcome.

Background Stimulating activities are associated with a decreased risk of dementia. However, the extent to which this reflects a protective effect of activity or non-participation resulting from dementia is debated. We investigated the association of stimulating leisure-time activity in late adulthood with the risk of dementia across up to two decades' follow-up. Methods We used data from five prospective cohort studies from Finland and Sweden. Mental, social, outdoor, consumptive and physical leisure-time activities were self-reported. Incident dementia was ascertained from clinical diagnoses or healthcare and death registers. Cox regression was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Results Of the 33 263 dementia-free individuals aged ≥50 years at baseline, 1408 had dementia during a mean follow-up of 7.0 years. Active participation in mental (HR: 0.52, 95% CI: 0.41 to 0.65), social (HR: 0.56 95% CI: 0.46 to 0.72), outdoor (HR: 0.70, 95% CI: 0.58 to 0.85), consumptive (HR: 0.67, 95% CI: 0.53 to 0.94) and physical (HR: 0.62, 95% CI: 0.51 to 0.75) activity, as well as variety (HR: 0.54, 95% CI: 0.43 to 0.68) and the overall frequency of activity (HR: 0.41, 95% CI: 0.34 to 0.49) were associated with a reduced risk of dementia in <10 years' follow-up. In ≥10 years' follow-up all associations attenuated toward the null. Conclusion Stimulating leisure-time activities are associated with a reduced risk of dementia in short-term but not long-term follow-up. These findings may reflect a reduction in leisure-time activity following preclinical dementia or dilution of the association over time. [ABSTRACT FROM AUTHOR]

Aims: The aim of the study was to estimate the effect of household relative poverty on the risk of diabetic ketoacidosis at diagnosis of children with type 1 diabetes using an international standard measurement of relative poverty. Methods: A national population‐based retrospective study was conducted. The Swedish National Diabetes Register (NDR) was linked with data from Sweden's public statistical agency (Statistics Sweden). Children who were diagnosed with new‐onset type 1 diabetes in the period of 2014–2019 were common identifiers. The definition of diabetic ketoacidosis was venous pH <7.30 or a serum bicarbonate level <18 mmol/L. The exposure variable was defined according to the standard definition of the persistent at‐risk‐of‐poverty rate used by the statistical office of the European Union (Eurostat) and several other European public statistical agencies. Univariate and multi‐variable analyses were used to calculate the effect of relative poverty on the risk of diabetic ketoacidosis. Results: Children from households with relative poverty had a 41% higher risk of diabetic ketoacidosis (1.41, CI 1.12–1.77, p = 0.004) and more than double the risk of severe diabetic ketoacidosis (pH <7.10) (RR 2.10, CI 1.35–3.25, p = 0.001), as compared to children from households without relative poverty. Conclusions: Relative poverty significantly increases the risk of diabetic ketoacidosis at onset of type 1 diabetes in children, even in a high‐income country with publicly reimbursed health care.

Aims: This study aims to investigate trends in four types of adolescent mental health problems; that is, psychosomatic symptoms, depressive symptoms, suicidal ideations, and suicide attempts 2004–2020. A second aim is to investigate the moderating roles of socioeconomic status and sex in these trends. Methods: The analysis is based on repeated cross-sectional data 2004–2020 among grade 9 students in secondary schools in a Swedish county. In total, data from 19,873 students were included in the analysis. We fitted linear and logistic regression equations and used survey-years' coefficients to estimate the trends. We also estimated the moderating effects of socioeconomic status and sex using interactions between survey year and socioeconomic status and sex, respectively. Results: The trends in all mental health problems declined over time. Through its interaction with survey year, socioeconomic status moderated the trends; psychosomatic symptoms (B = −0.115, P <0.001), depressive symptoms (B = −0.084, P <0.001) and suicidal ideations (odds ratio 0.953, confidence interval 0.924–0.983) significantly declined over time among those with high socioeconomic status. However, socioeconomic status did not have an association with the trend in suicide attempts. Interaction between sex and year of survey was associated with significant decreasing trends in depressive symptoms and suicidal ideations only among girls. Conclusions: Adolescent mental health problems have decreased over time, but only for adolescents with high socioeconomic status, or only in depressive symptoms and suicidal ideations for girls. The results shed light on the growing inequalities in health outcomes across levels of socioeconomic status. [ABSTRACT FROM AUTHOR]

Background and Hypothesis Recent research showed that young people who presented to hospital with self-harm in Finland had a significantly elevated risk of later psychosis. We investigated the prospective relationship between hospital presentation for self-harm and risk of psychosis in an unprecedentedly large national Swedish cohort. Study Design We used inpatient and outpatient healthcare registers to identify all individuals born between 1981 and 1993 who were alive and living in Sweden on their 12th birthday and who presented to hospital one or more times with self-harm. We compared them with a matched cohort, followed up for up to 20 years, and compared the cumulative incidence of psychotic disorders. Furthermore, we examined whether the strength of the relationship between hospital presentation for self-harm and later psychosis changed over time by examining for cohort effects. Study Results In total, 28 908 (2.0%) individuals presented to hospital with self-harm without prior psychosis diagnosis during the follow-up. For individuals who presented to hospital with self-harm, the cumulative incidence of diagnosed psychosis was 20.7% at 20 years follow-up (hazard radio = 13.9, 95% CI 13.3–14.6, P -value <5 × 10−308). There was no evidence of a dilution of the effect over time: while the incidence of hospital self-harm presentation increased, this did not result in an attenuation over time of the strength of the relationship between hospital self-harm presentation and subsequent psychosis. Conclusions Individuals who present to hospital with self-harm in their teens and 20s represent an important risk group for psychosis prediction and prevention. [ABSTRACT FROM AUTHOR]

Purpose: To study the association between the use of drugs for hypertension or heart failure, particularly diuretics, and risk of death in COVID-19. Methods: We conducted a cohort study, based on record linked individual-based data from national registers, of all Swedish inhabitants 50 years and older (n = 3,909,321) at the start of the first SARS-CoV-2 wave in Sweden. The association between use of angiotensin-converting enzyme inhibitors (ACEI), angiotensin II receptor blockers (ARB), thiazides, loop diuretics, aldosterone antagonists, beta blocking agents and calcium channel blockers at the index date 6 March 2020, and death in COVID-19 during 7 March to 31 July 2020, was analysed using Cox-proportional hazards regression, adjusted for a wide range of possible confounders. Results: Use of loop diuretics was associated with higher risk [adjusted hazard ratio (HR) 1.26; 95% confidence interval (95% CI) 1.17–1.35] and thiazides with reduced risk (0.78; 0.69–0.88) of death in COVID-19. In addition, lower risk was observed for ACEI and higher risk for beta-blocking agents, although both associations were weak. For ARB, aldosterone antagonists and calcium channel blockers no significant associations were found. Conclusion: In this nationwide cohort of nearly 4 million persons 50 years and older, the use of loop diuretics was associated with increased risk of death in COVID-19 during the first SARS-CoV-2 wave in Sweden. This contrasted to the decreased risk observed for thiazides. As treatment with loop diuretics is common, particularly in the elderly, the group most affected by severe COVID-19, this finding merit further investigation. [ABSTRACT FROM AUTHOR]

Background: Despite the better prognosis associated with human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC), some patients experience relapse and succumb to the disease; thus, there is a need for biomarkers identifying these patients for intensified treatment. Leucine-rich repeats and immunoglobulin-like domain (LRIG) protein 1 is a negative regulator of receptor tyrosine kinase signaling and a positive prognostic factor in OPSCC. Studies indicate that LRIG1 interacts with the LIM domain 7 protein (LMO7), a stabilizer of adherence junctions. Its role in OPSCC has not been studied before. Methods: A total of 145 patients diagnosed with OPSCC were enrolled. Immunohistochemical LMO7 expression and staining intensity were evaluated in the tumors and correlated with known clinical and pathological prognostic factors, such as HPV status and LRIG1, CD44, Ki67, and p53 expression. Results: Our results show that high LMO7 expression is associated with significantly longer overall survival (OS) (p = 0.044). LMO7 was a positive prognostic factor for OS in univariate analysis (HR 0.515, 95% CI: 0.267–0.994, p = 0.048) but not in multivariate analysis. The LMO7 expression correlated with LRIG1 expression (p = 0.048), consistent with previous findings. Interestingly, strong LRIG1 staining intensity was an independent negative prognostic factor in the HPV-driven group of tumors (HR 2.847, 95% Cl: 1.036–7.825, p = 0.043). Conclusions: We show for the first time that high LMO7 expression is a positive prognostic factor in OPSCC, and we propose that LMO7 should be further explored as a biomarker. In contrast to previous reports, LRIG1 expression was shown to be an independent negative prognostic factor in HPV-driven OPSCC. [ABSTRACT FROM AUTHOR]

Background: Attention deficit hyperactivity disorder (ADHD) is associated with risk taking and negative health‐related outcomes across the lifespan. Due to delay in referral and diagnostics, young females with ADHD may not be identified, nor appropriately supported by adequate interventions. Methods: A total of 85,330 individuals with ADHD, all of whom were residents in Stockholm County between January 01, 2011, and December 31, 2021, were included as participants in this population‐based, cross‐sectional cohort study. Population controls (n = 426,626) were matched by age, sex, and socioeconomic status (SES). Data was obtained from Regional Healthcare Data Warehouse of Region Stockholm (VAL) in Stockholm County. Exposure was ADHD‐index, defined as the first record of either ICD‐10 F90 diagnosis and/or ATC‐code for stimulant or non‐stimulant ADHD‐medication during the study period. Primary outcome was age at ADHD‐index. Secondary outcome measures were psychiatric comorbidity, pharmacological treatment, and health care utilization, prior to and after ADHD‐index. Results: Females were older at ADHD‐index (23.5 years, SD 13.8) compared to males (19.6 years, SD 13.9, 95% CI of difference 3.74–4.11). Overall, females with ADHD showed higher rates of psychiatric comorbidity, pharmacological treatment, and health care utilization, compared to males with ADHD and female controls. Conclusions: Females with ADHD receive diagnosis and treatment for ADHD approximately 4 years later than males. They have a higher burden of comorbid psychiatric conditions and health care utilization, compared to males with ADHD and female controls, both prior to and after ADHD‐index. To prevent long‐term adverse consequences for females with ADHD, methods, and tools for early diagnosis and treatments that mitigate personal suffering and societal burden are warranted.

Background: Prior research has reported an association between divorce and suicide attempt. We aimed to clarify this complex relationship, considering sex differences, temporal factors, and underlying etiologic pathways. Methods: We used Swedish longitudinal national registry data for a cohort born 1960–1990 that was registered as married between 1978 and 2018 (N = 1 601 075). We used Cox proportional hazards models to estimate the association between divorce and suicide attempt. To assess whether observed associations were attributable to familial confounders or potentially causal in nature, we conducted co-relative analyses. Results: In the overall sample and in sex-stratified analyses, divorce was associated with increased risk of suicide attempt (adjusted hazard ratios [HRs] 1.66–1.77). Risk was highest in the year immediately following divorce (HRs 2.20–2.91) and declined thereafter, but remained elevated 5 or more years later (HRs 1.41–1.51). Divorcees from shorter marriages were at higher risk for suicide attempt than those from longer marriages (HRs 3.33–3.40 and 1.20–1.36, respectively). In general, HRs were higher for divorced females than for divorced males. Co-relative analyses suggested that familial confounders and a causal pathway contribute to the observed associations. Conclusions: The association between divorce and risk of suicide attempt is complex, varying as a function of sex and time-related variables. Given evidence that the observed association is due in part to a causal pathway from divorce to suicide attempt, intervention or prevention efforts, such as behavioral therapy, could be most effective early in the divorce process, and in particular among females and those whose marriages were of short duration.

We investigated the association between maternal grandmaternal early pregnancy body mass index (BMI) and grandoffspring stillbirth risk in a Swedish population-based 3-generation cohort of 176 908 grandmothers (F0), 197 579 mothers (F1), and 316 459 grandoffspring (F2) born 1997-2016. There were 998 stillbirths (risk, 3.2 per 1000 births). Compared with grandmaternal BMI 18.5-24.9, adjusted relative risks (RRs) of grandoffspring stillbirth for BMIs of 25.0-29.9 and ≥30.0 were, respectively, 1.41 (95% CI, 1.15-1.72) and 1.62 (95% CI, 1.14-2.30). RRs for corresponding maternal (F1) BMI categories were, respectively, 1.32 (95% CI, 1.06-1.65) and 1.77 (95% CI, 1.39-2.25). Maternal BMI mediated only 19% of this relationship. Grandmaternal preeclampsia and maternal small-for-gestational age (SGA) birth were related to increased F2 stillbirth risk but did not mediate the association between grandmaternal BMI and grandoffspring stillbirth risk. To explore whether this association was explained by factors shared within families, we studied the relationship of maternal full sisters' BMI and stillbirth risk in 101 368 pregnancies. Stillbirth RRs for full sisters' BMI 25.0-29.9 and ≥30.0 compared with 18.5-24.9 were, respectively, 0.76 (95% CI, 0.51-1.13) and 0.88 (95% CI, 0.55-1.40). In conclusion, grandmaternal overweight and obesity were associated with grandoffspring stillbirth. This association is not fully explained by shared familial factors. [ABSTRACT FROM AUTHOR]

Background Limited language fluency can impede healthcare system navigation. In Sweden, the national telehealth line (Healthcare Guide 1177) offers interpretation in Arabic and Somali. We compared calls by language to identify differences in healthcare use for immigrant populations, focusing on three contact causes: pregnancy; vomiting or nausea in children; and worry/anxiety. Methods We conducted a cross-sectional analysis of 3.9 million (n  = 18 351 Arabic, n  = 7199 Somali) telehealth calls (2014–18). Using multivariable logistic regression, we investigated associations between language of the call (Arabic, Somali, non-interpreted) and each contact cause. Potential confounders (age, region, year, and additionally for vomiting or nausea, month) and an interaction between age and language were considered. Results Compared with non-interpreted calls, interpreted calls were associated with increased odds of being for pregnancy, especially for 19 to 29-year-olds [adjusted odds ratio (aOR) (95% CI) = 4.04 (3.66–4.46) and 4.60 (4.05–5.23), for Arabic and Somali calls, respectively]. Vomiting or nausea showed similar results, with aOR increasing with age: from 0.90 (0.75–1.07) (Arabic, <1 year) to 3.79 (2.86–5.01) (Somali, 5–9 years). In contrast, in unadjusted analyses, Arabic and Somali calls were associated with decreased odds of being for worry/anxiety [OR = 0.47 (0.38–0.58) and 0.34 (0.21–0.50)], respectively, compared with non-interpreted calls. Conclusion Our results suggest callers to the interpreted lines may need additional assistance navigating the healthcare system for pregnancy and for vomiting or nausea among children. These findings can inform healthcare services planning for immigrants to Sweden and highlight a novel use of telehealth data as a way to uncover disparities in healthcare use within a multi-linguistic population.

Aim: A primary goal of obstetric care of women with type 1 diabetes (T1D) is to reduce the risks of preterm birth (PTB). Besides hyperglycaemia, maternal obesity is an important risk factor for PTB in T1D. However, it's unclear if public health efforts decreased risks of maternal obesity and PTB in pregnancies with T1D. We examined time‐trends over the last 20 years in the distribution of gestational ages at birth (GA) in offspring of women with T1D in Sweden, and in maternal BMI in the same mothers. Methods: Population‐based cohort study, using data from national registries in Sweden. To capture differences not only in the median values, we used quantile regression models to compare the whole distributions of GA's and early pregnancy BMI between deliveries in 1998–2007 (P1) and 2008–2016 (P2). Multivariable models were adjusted for differences in maternal age, smoking and education between periods 1 and 2. Results: The study included 7639 offspring of women with T1D between 1998 and 2016. The 10% percentile GA, increased with 0.09 days (95% CI: −0.11 to 0.35) between P1 and P2. The 90% percentile for BMI was 1.20 kg/m2 higher (95% CI: 0.57 to 1.83) in P2. Risks of PTB remained stable over time also when adjusting for maternal BMI. Conclusion: Despite modern diabetes management, the distribution of GA, and consequently the risk of PTB in T1D, remained unchanged from 1998 to 2016. During the same time, maternal BMI increased, particularly in the already obese. [ABSTRACT FROM AUTHOR]

Aims: The aim of this study was to investigate associations between having visited the theatre/cinema and an arts exhibition during the past year and all-cause, cardiovascular disease (CVD), cancer and other-cause mortality. Methods: The 2008 public health postal survey in Scania, Sweden, was distributed to a stratified random sample of the adult population (18–80 years old). The participation rate was 54.1%, and 25,420 participants were included in the present study. The baseline 2008 survey data were linked to cause-of-death register data to create a prospective cohort with 8.3-year follow-up. Associations between visit to the theatre/cinema, visit to an arts exhibition and mortality were investigated in survival (Cox) regression models. Results: Just over a quarter (26.5%) had visited both the theatre/cinema and an arts exhibition during the past year, 36.6% only the theatre/cinema, 4.9% only an arts exhibition and 32% neither of the two. Not visiting the theatre/cinema during the past year was associated with higher all-cause and CVD mortality. Not visiting an arts exhibition was associated with higher all-cause and other-cause mortality. The combination of having visited neither the theatre/cinema nor an arts exhibition during the past year was associated with higher all-cause, CVD and other-cause mortality. Conclusions: There is an association between attending arts and culture activities and a reduced risk of CVD and other-cause mortality but not cancer mortality, although model imperfections are possible.

Aims: To assess the association between experiences of discrimination and mental health among the Sámi population in Sweden. Methods: Cross-sectional study among the self-identified Sámi population living in Sweden in 2021, registered in the electoral roll of the Sámi Parliament, the reindeer mark register and the 'Labour statistics based on administrative sources'. The analysis was based on a final sample of 3658 respondents aged between 18 and 84 years. Adjusted prevalence ratios aPRs for psychological distress (Kessler scale), self-reported anxiety and depression were estimated for four different forms of discrimination (direct experience of discrimination, offended because of ethnicity, historical trauma, and combined discrimination). Results: Higher aPRs of psychological distress, anxiety and depression were observed in women experiencing direct discrimination because of their ethnicity, having been offended because of their ethnicity, and those with a family history of discrimination. Among men, higher aPRs for psychological distress were observed in those experiencing the four different forms of discrimination, but not for anxiety. Depression was only detected in the case of having been offended. Adding experiences of discrimination was associated with a higher prevalence of negative outcomes for all the indicators in women and for psychological distress in men. Conclusions: The observed association between experiences of discrimination and mental health problems would support a gender approach when considering ethnic discrimination in public health policies concerning the Sámi in Sweden.

Aims: Back pain and neck/shoulder pain are common among nurses. The aim of this study was to investigate the association between nurses' exposure to a demanding psychosocial work environment during the first three years after graduation and the occurrence of severe back pain and neck/shoulder pain in the longer term, 11–15 years later. Methods: The Longitudinal Analysis of Nursing Education (LANE) study (nursing graduates from 26 Swedish universities in the years 2002, 2004 and 2006) was used to create two risk cohorts of nurses not reporting severe back pain (n =1764) or neck/shoulder pain (n =1707). Nurses exposed to a demanding psychosocial work environment for one, two or three of the first three years in their career were compared to nurses not having a demanding psychosocial work environment for any of these three years regarding the incidence of severe back pain or neck/shoulder pain at follow-up, 11–15 years later. Relative risks (RR) with 95% confidence intervals (CI) were calculated using binomial regression. Results: The RR (95% CI) of having severe back pain for nurses who had a demanding psychosocial work environment for one of the three years was 1.36 (0.82–2.28) and 2.08 (1.21–3.57) for two of the three years and 2.82 (1.43–5.55) for all three years. Corresponding RRs (95% CIs) for severe neck/shoulder pain were 1.35 (0.87–2.10), 1.49 (0.88–2.51) and 1.41 (0.62–3.20), respectively. Conclusions: Nurses who were repeatedly exposed to a demanding psychosocial work environment early in their career reported severe back pain to a higher extent in the longer term.

Background: Moral distress is a problem and negative experience among health-care professionals. Various instruments have been developed to measure the level and underlying reasons for experienced moral distress. The moral distress thermometer (MDT) is a single-tool instrument to capture the level of moral distress experienced in real-time. Aim: The aim of this study was to translate the MDT and adapt it to the Swedish cultural context. Research design: The first part of this study concerns the translation of MDT to the Swedish context, and the second part the psychometric testing of the Swedish version. Participants and research context: 89 healthcare professionals working at a hospital in northern Sweden participated. Convergent validity was tested between MDT and Measure of Moral Distress-Healthcare Professionals (MMD-HP), and construct validity was tested by comparing MDT scores among healthcare professionals. MDT was compared with responses to the final questions in MMD-HP. One-way ANOVA, Welch's ANOVA, Games–Howell post-hoc test and Pearson's correlation analysis were done. Ethical considerations: The study was approved by the Swedish Ethics Review Authority (dnr 2020-04120) in accordance with Helsinki Declaration. Results: The translated Swedish version of MDT was described as relevant to capture the experience of moral distress. The mean value for MDT was 2.26, with a median of 2 and a mode value of 0. The result showed moderate correlations between the MDT and MMD-HP total scores. There was a significant difference when comparing MDT and healthcare professionals who had never considered leaving their present position with those who had left and those who had considered leaving but had not done so, with the latter assessing significantly higher moral distress. Conclusion: The MDT is an easily available instrument useful as an extension to MMD-HP to measure the real-time experience of moral distress among healthcare professionals in a Swedish context.

Purpose: To explore the occurrence of work adjustments for people with multiple sclerosis (MS) across types of occupations (managerial, office, and manual workers). Methods: All working-aged (20–50 years) residents in Sweden diagnosed with MS were invited to participate in a web-based survey in 2021. Responses were linked to individual-level nationwide registers. Descriptive analyses were conducted to compare sociodemographic and clinical variables across occupations as well as other responses. The odds ratio of having any adjustment at work was determined using multinomial logistic regression. Results: From all 4412 respondents (52% response rate), 3313 employees were included. The majority were women (72%) and had low (24.2%) or mild disease severity (44.7%). Nevertheless, different work adjustments across occupations were observed. Compared to the other occupations, office workers reported more invisible symptoms, more work adjustments and considered adapted schedules as the most important adjustment. On the contrary, more managers reported having no limiting symptoms and consequently, disclosed their diagnosis less often. They also reported having fewer work adjustments and more opportunities to modify their work than office and manual workers. Manual workers had a higher likelihood to report needing more support at work than office workers and managers. Further, a higher likelihood of having work adjustments was associated with progressive MS, higher MS severity, and invisible symptoms. Conclusion: A more severe clinical profile of MS was associated with having work adjustments. The physical demands and responsibilities of an occupation play an important role when requesting and getting work adjustments amongst employees with MS. [ABSTRACT FROM AUTHOR]

Introduction: Hip arthroplasty is a common orthopaedic procedure worldwide. There is an ongoing debate related to the fixation and anaesthesia impact on the 30-day mortality, particularly in the aging population with higher American Society of Anaesthesiology (ASA) Physical-Status. Aim: To study the 30-day all-cause mortality in patients undergoing primary hip arthroplasty, with regards to the impact of age, ASA-class, anaesthesia techniques, indication for surgery and fixation techniques. Materials and methods: Perioperative data for primary hip arthroplasty procedures for osteoarthritis and hip fractures registered in the Swedish Perioperative Registry (SPOR) between 2013 and June 2022 were collected. Binary logistic regressions were performed to assess the impact of age, ASA-class, anaesthetic technique, indication for surgery and fixation on odds ratio for 30-day mortality in Sweden. Results: In total, 79,114 patients, 49,565 with osteoarthritis and 29,549 with hip fractures were included in the main study cohort. Mortality was significantly higher among hip fracture patients compared with osteoarthritis, cumulative 8.2% versus 0.1% at 30-days respectively (p < 0.001). Age above 80 years (OR3.7), ASA 3–5 (OR3.3) and surgery for hip fracture (OR 21.5) were associated with significantly higher odds ratio, while hybrid fixation was associated with a significantly lower odds ratio (OR0.4) of 30-day mortality. In the same model, for the subgroups of osteoarthritis and hip fracture, only age (OR 3.7) and ASA-class (OR 3.3) had significant impact, increasing the odds ratio for 30-day mortality. Hemi arthroplasty was commonly used among the hip fracture patients 20.453 (69.2%), and associated with a significantly higher odds ratio for all-cause 30-day mortality as compared to total hip arthroplasty when adjusting for age and ASA-class and fixation 2.3 (95%CI 1.9–2.3, p < 0.001). Conclusions: All-cause 30-day mortality associated with arthroplasty differed significantly between the two cohorts, hip fracture, and osteoarthritis (8.2% and 0.1% respectively) and mortality expectedly increased with age and higher ASA-class. Anaesthetic method and cement-fixation did not impact the odds ratio for all-cause 30-day mortality after adjustment for age and ASA-class. [ABSTRACT FROM AUTHOR]

Background and aims: Despite the high prevalence and negative effects of hazardous substance use, few young adults enter treatment. Community Reinforcement and Family Training (CRAFT), a support programme for concerned significant others of people with substance use disorders, has proved efficacious in promoting treatment entry. The aim of the current trial was to compare the efficacy of CRAFT with an active control for parents of young adults (aged 18–24 years) with hazardous substance use. Design: This was a randomized controlled superiority trial comparing CRAFT (n = 58) with an active control group receiving manualized counselling (n = 55), with outcome assessments at 6, 12 and 24 weeks (primary end‐point). A sequential design with a stopping rule was added post recruitment commencement. Setting: The study took place in two outpatient clinics for young adults in Stockholm, Sweden, and subsequently via video‐conference due to COVID‐19. Participants: Between October 2018 and May 2021, 113 participants (92% female) who were parents of young adults (87% male) were recruited. Recruitment was discontinued when 70% of the planned sample had been recruited, following an interim analysis of the primary outcome showing no difference between conditions. Intervention and comparator: Participants were randomized (ratio 1 : 1) to eight manual‐based individual CRAFT sessions or five individual manual‐based counselling sessions + one voluntary psychoeducative group session, delivered over maximum 14 weeks. Measurements The primary outcome measure was the rate of young adult entry in substance use treatment during the trial period (24 weeks). Findings At the 24 weeks follow‐up, 19 (33%) of CRAFT participants and 17 (31%) of counselling participants had reported young adult treatment entry, with no difference between conditions (odds ratio CRAFT versus counselling 0.84, 95% confidence interval = 0.35; 1.99, P = 0.700). Both conditions reported clinically relevant reductions in young adult substance use, but no change in participants' levels of depression, anxiety or stress. Conclusions: This trial showed no statistically significant evidence that Community Reinforcement and Family Training (CRAFT), a support programme for concerned significant others of people with substance use disorders, is more efficacious than manual‐based counselling regarding treatment entry for young adults.

Objectives: This study investigated the relationship between biological maturation and success in adolescence and adulthood in male Swedish ice hockey players. Methods: Anthropometric records of players in certified ice hockey high schools between 1998 and 2017 were retrieved (n = 4787). The database was complemented with records of Swedish junior national teams (U16, U18, U20) and National Hockey League (NHL) appearances. Biological maturation was recorded as a percentage of adult height (%AH), and selection probabilities were estimated using a generalised linear mixed effects model. Biological age was determined by comparing players with age-matched growth reference values. Categories of %AH, standard deviation z-scores and biological age offset describing early, on-time and late maturation were created. Results: A total of 217 players had played on the U16 national team (junior success), and 96 reached the NHL (adult success). The difference [95% confidence interval (CI)] in baseline %AH between players with junior versus adult success was − 0.75 (− 0.39, − 1.11). Looking at age-offset categories in junior success, 30% of players were early maturing and 19% of players were late maturing, showing a bias towards early maturation (p < 0.01). In contrast, more late-maturing players (40%) achieved adult success than early-maturing players (25%), and NHL players had significantly later maturation [%AH: − 0.48 (− 0.80, − 0.16)] than non-NHL players. Conclusion: This unique 20-year analysis shows that junior success in male ice hockey is positively related to early maturation, while adult success is inversely related to advanced maturation. Ice hockey organisations should implement maturation assessments to optimise the development of both late- and early-matured players. [ABSTRACT FROM AUTHOR]

Background: This longitudinal register study aimed to investigate the association between gambling disorder (GD) and work disability and to map work disability in subgroups of individuals with GD, three years before and three years after diagnosis. Methods: We included individuals aged 19–62 with GD between 2005 and 2018 (n = 2830; 71.1% men, mean age: 35.1) and a matched comparison cohort (n = 28 300). Work disability was operationalized as the aggregated net days of sickness absence and disability pension. Generalized estimating equation models were used to calculate adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for the risk of long-term work disability (>90 days of work disability/year). Secondly, we conducted Group-based Trajectory Models on days of work disability. Results: Individuals with GD showed a four-year increased risk of long-term work disability compared to the matched cohort, peaking at the time of diagnosis (AOR = 1.89; CI 1.67–2.13). Four trajectory groups of work disability days were identified: constant low (60.3%, 5.6–11.2 days), low and increasing (11.4%, 11.8–152.5 days), medium–high and decreasing (11.1%, 65.1–110 days), and constant high (17.1%, 264–331 days). Individuals who were females, older, with prior psychiatric diagnosis, and had been dispensed a psychotropic medication, particularly antidepressants, were more likely to be assigned to groups other than the constant low. Conclusion: Individuals with GD have an increased risk of work disability which may add financial and social pressure and is an additional incentive for earlier detection and prevention of GD.

Objectives: Women living with HIV are underrepresented in clinical trials assessing outcomes of antiretroviral treatment (ART), justifying the need for observational studies. We investigated differences in viral non‐suppression between women and men in the Swedish InfCareHIV cohort and analysed results in relation to biological and socio‐demographic variables and patient‐reported outcome measures (PROMs). Methods: The study included people living with HIV (PLWH) aged ≥18 years, who initiated ART at least 6 months prior to inclusion. Data from the InfCareHIV registry 2011–2018 were collected. Associations between variables and HIV RNA ≥50 copies/mL were investigated in uni‐ and multivariable analyses using generalized estimating equations, providing relative risks (RRs) as effect size. Results: The study included 38% (n = 2981) women. Women were more likely to have HIV RNA ≥50 copies/mL than were men [RR = 1.20, 95% confidence interval (CI): 1.10–1.31]. After adjusting for origin and route of transmission, sex at birth was no longer associated with viral non‐suppression. PROMs were available in 52.4% of PLWH, and items associated with viral non‐suppression were impaired adherence in women (RR = 2.38, 95% CI: 1.79–3.17) and men (RR 1.84, 95% CI: 1.40–2.42), and experience of side effects in women (RR = 1.49, 95% CI: 1.10–2.02). Conclusions: This observational study found a 20% higher relative risk of viral non‐suppression in women than in men and the difference was associated with socio‐demographic factors. The associations between PROMs and viral non‐suppression varied between women and men. PROMs are important health outcomes that may identify PLWH in need of support to achieve viral non‐suppression.

Background: Standardised terminologies and classification systems play an increasingly important role in the continuous work towards high quality patient care. Currently, a standardised terminology for nutrition care, the Nutrition Care Process (NCP) Terminology (NCPT), is being implemented across the world, with terms for four steps: Nutrition Assessment (NA), Nutrition Diagnosis (ND), Nutrition Intervention (NI) and Nutrition Monitoring and Evaluation (NME). Objective: To explore associations between individual and contextual factors and implementation of a standardised NCPT among Swedish dietitians. Method: A survey was completed by 226 dietitians, focussing on: (a) NCPT implementation level; (b) individual factors; and (c) contextual factors. Associations between these factors were explored through a two-block logistic regression analysis. Results: Contextual factors such as intention from management to implement the NCPT (OR (odds ratio) ND 15.0, 95% Confidence Interval (CI) 3.9–57.4, NME 3.7, 95% CI 1.1–13.0) and electronic health record (EHR) headings from the NCPT (OR NI 3.6, 95% CI 1.4–10.7, NME 3.8, 95% CI 1.1–11.5) were associated with higher implementation. A positive attitude towards the NCPT (model 1 OR ND 3.8, 95% CI 1.5–9.8, model 2 OR ND 5.0, 95% CI 1.4–17.8) was also associated with higher implementation, while other individual factors showed less association. Conclusion: Contextual factors such as intention from management, EHR structure, and pre-defined terms and headings are key to implementation of a standardised terminology for nutrition and dietetic care. Implications for practice: Clinical leadership and technological solutions should be considered key areas in future NCPT implementation strategies. [ABSTRACT FROM AUTHOR]

Background: Explanations for the disproportional COVID-19 burden among immigrants relative to host-country natives include differential exposure to the virus and susceptibility due to poor health conditions. Prior to the pandemic, immigrants displayed deteriorating health with duration of residence that may be associated with increased susceptibility over time. The aim of this study was to compare immigrant–native COVID-19 mortality by immigrants' duration of residence to examine the role of differential susceptibility. Methods: A population-based cohort study was conducted with individuals between 18 and 100 years old registered in Sweden between 1 January 2015 and 15 June 2022. Cox regression models were run to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Results: Inequalities in COVID-19 mortality between immigrants and the Swedish-born population in the working-age group were concentrated among those of non-Western origins and from Finland with more than 15 years in Sweden, while for those of retirement age, these groups showed higher COVID-19 mortality HRs regardless of duration of residence. Both age groups of immigrants from Africa and the Middle East showed consistently higher COVID-19 mortality HRs. For the working-age population: Africa: HR<15: 2.46, 95%CI: 1.78, 3.38; HR≥15: 1.49, 95%CI: 1.01, 2.19; and from the Middle East: HR<15: 1.20, 95%CI: 0.90, 1.60; HR≥15: 1.65, 95%CI: 1.32, 2.05. For the retirement-age population: Africa: HR<15: 3.94, 95%CI: 2.85, 5.44; HR≥15: 1.66, 95%CI: 1.32, 2.09; Middle East: HR<15: 3.27, 95%CI: 2.70, 3.97; HR≥15: 2.12, 95%CI: 1.91, 2.34. Conclusions: Differential exposure, as opposed to differential susceptibility, likely accounted for the higher COVID-19 mortality observed among those origins who were disproportionately affected by the pandemic in Sweden.

Objective: Most international studies have concluded that exposure to the COVID-19 pandemic was associated with worse mental health. Sweden implemented lighter restrictions than many other countries. We evaluated the association between changes in exposure of COVID-19 restrictions and changes in mental health problems among Swedish adolescents. Method: Repeated cross-sectional data were derived from the Stockholm school survey, mandatory for all students in municipal schools and voluntary for students in private schools. Unexposed students were assessed in the year 2020 and exposed were assessed in 2022. Mental health was assessed using items similar to the psychosomatic problem scale. All variables were dichotomised, and a non-parametric logistic regression was used to evaluate associations. Results: A significant positive association was found between exposure of COVID-19 restrictions and self-reports of five to seven mental health problems a week for girls (odds ratio (OR) 1.29, 95% confidence interval (CI) 1.18–1.41), but a non-significant association was found for boys (also after controlling for relevant covariates). Among boys and girls (shown), changes in mental health during the pandemic were moderated by social support from parents (OR 2.23, 95% CI 1.98–2.51), bullying victimisation (OR 2.24, 95% CI 2.06–2.66), a sensation-seeking temperament (OR 1.40, 95% CI 1.24–1.58) and school achievement (OR 1.34, 95% CI 1.18–1.51). Conclusions: Compared with boys, adolescent girls self-reported worse mental health following COVID-19 exposure. Girls may have been more affected by social distancing regulations in Sweden during the pandemic than boys and may require additional psychosocial support post-pandemic. Social support from parents may play an important role. [ABSTRACT FROM AUTHOR]
