- Introduction: Recently settled refugee populations have consistently been reported to have high rates of mental health problems, particularly Post-traumatic stress disorder, depression, and anxiety disorders. The aim of this study was to investigate psychotropic drug use among young adult refugees according to duration of residence during the first 10 years in Sweden. Methods: Cross-sectional register study of a national cohort of 43 403 refugees and their families (23-35 years old) from Iraq, Iran, Eritrea, Ethiopia, Somalia and Afghanistan and a comparison population of 1.1 million Swedish-born residents. Logistic regression was used to assess the association between duration of residence in Sweden and the dispensing of at least one psychotropic medication during 2009 in four categories (any drug, neuroleptics, antidepressants and anxiolytics/hypnotics), adjusting for age, gender and domicile. Results: Rates of dispensed psychotropic drugs among recently settled refugees were low, compared to the Swedish-born, with an increase with duration of residence. For refugee men and women from Iraq/Iran who had resided for 0-3 years the adjusted ORs compared to Swedish natives, were 0.83 (95% CI 0.77-0.90) and 0.48 (0.44-0.53) respectively; for men and women from the Horn of Africa the ORs were 0.50 (0.42-0.61) and 0.36 (0.30-0.41) respectively. After 7-10 years of residence, the ORs in these refugee groups approached the Swedish comparison population. Refugees from Afghanistan presented ORs similar to the Swedish-born, with no consistent trend by duration of residence. Women from the Horn of Africa and Iraq/Iran consumed less psychotropic drugs compared with men from these regions of origin, relative to the Swedish-born (p < 0.01). The ORs for dispensed neuroleptics were similar between the different refugee study groups, while the ORs for dispensed antidepressants differed fourfold between the group with the lowest (Horn of Africa) and the highest (Afghanistan). Conclusion: The rates of dispensed psychotropic drugs in the newly settled refugee populations in this study were low, with an increase with longer duration of residence. This pattern suggests barriers to access mental health care. Interventions that can lower these barriers are needed to enable newly settled refugees to access mental health care on equal terms with the native population.

- AIMS: Peak left ventricular (LV) relaxation normally precedes peak filling (E), which supports the hypothesis that LV suction contributes to early-diastolic filling. The significance of similar temporal discordance in late diastole has previously not been studied. We describe the time relationships between mitral annular motion and LV filling in early and late diastole and examine the effect of normal ageing on these time intervals. METHODS AND RESULTS: A total of 128 healthy subjects aged 25-88 years were studied. Transmitral and pulmonary venous flow reversals (Ar) were recorded by Doppler echocardiography. Mitral annular diastolic displacement-early (E(m)) and late (A(m))-were recorded by Doppler tissue imaging. With reference to electrocardiographic R and P-waves, the following measurements were made: R to peak E-wave (R-E) and E(m) (R-E(m)); onset P to peak A-wave (P-pA), A(m) (P-pA(m)), and Ar (P-pAr). The differences between [(R-E) and (R-E(m))] for early-diastolic temporal discordance (EDTD) and [(P-A) and (P-A(m))] for late-diastolic temporal discordance (LDTD) were calculated. Isovolumic relaxation time (IVRT) was also measured. Early-diastolic temporal discordance was approximately 26 ms in all age groups. Late-diastolic temporal discordance, however, was inversely related to age (r = -0.35, P < 0.001) and IVRT (r = -0.34, P < 0.001) and therefore decreased in the elderly vs. young (13 +/- 10 vs. 23 +/- 10 ms; P < 0.001). In multivariate analysis, age failed to predict LDTD in the presence of IVRT. A, A(m), and Ar were simultaneous at onset, and peak A(m) coincided with peak Ar in all age groups (r = 0.97, P < 0.001). No significant differences were noted in the RR intervals. CONCLUSIONS: Sequential prolongation of IVRT with ageing reduces LDTD, thus converging the peaks of A(m), A, and Ar (atrial mechanical alignment)-a potential novel method to identify subjects at increased dependency on atrial contraction for late-diastolic filling.

- AIMS: Although pulmonary venous flow reversal (Ar) is useful in the evaluation of left ventricular (LV) diastolic function, it is often difficult to study with transthoracic echocardiography (TTE). We determined the relationship between Ar and left atrial (LA) mechanical function and sought to define surrogate measurements for Ar. METHODS AND RESULTS: A total of 130 healthy subjects, mean age 54.3+/-18.3 years, 62 women, were studied and classified into three groups: [young (Y), 25-44 years; n=44], [middle-age (M), 45-64 years; n=43] and [elderly (E), > or =65 years; n=43]. Pulmonary venous flow and LV inflow studies were performed by TTE and LV basal free-wall motion was studied by Doppler tissue imaging (DTI). All images were acquired with a superimposed electrocardiogram. RR interval was similar in all groups while LA dimension and PR interval were increased in Group E vs. Y (P<0.001). LA contraction (A(m)) on DTI, transmitral A-wave (A) and Ar were simultaneous and started 84ms after onset of P wave and this interval increased with age (P=0.02). Similarly, the time intervals from the same landmark to peak A(m), A, and Ar were prolonged with age (all, P<0.001). Despite this prolongation, peak A(m) coincided with peak Ar in every age group (r=0.97, P<0.001) and Ar acceleration and deceleration times were consistently equal. CONCLUSION: The timing of A(m) obtained by DTI can be used to accurately estimate corresponding measurements of Ar recorded by TTE in subjects without cardiac disease.

- Background The COVID Stress Scales (CSS) assess health- and contamination-related distress in the face of a medical outbreak like the ongoing COVID-19 pandemic. Though the CSS is translated into 21 languages, it has not been validated in a Swedish national sample. Aim Our general objective is to provide a translation, replication, and validation of the CSS and test its convergent- and discriminant validity in relation to anxiety, health anxiety, depression, and stress in the general Swedish population. We also present latent psychometric properties by modelling based on item response theory. Methods Participants consisted of 3044 Swedish adults (> 18 years) from a pre-stratified (gender, age, and education) sample from The Swedish Citizen Panel. Mental health status was assessed by validated instruments, including the CSS, PHQ-4, SHAI-14, and PSS-10. Results Results indicate that our Swedish translation of CSS has good psychometric properties and consists of 5 correlated factors. Discussion The CSS is useful either as a unidimensional or multidimensional construct using the CSS scales to measure key facets of pandemic-related stress. Conclusions The findings support the cross-cultural validity of the CSS and its potential utility in understanding many of the emotional challenges posed by the current and future pandemics.

- Health inequality linked to socioeconomic status (SES) has increased in many parts of the world. Since economic inequality also has been reported to be on the rise, it is pivotal to investigate how socioeconomic inequality affects health disparities annually. The present study is based on a yearly repeated cross-sectional probability sample of Swedish citizens (N = 141 619) collected between 1999 and 2021. We show that the relative level of SES has increased significantly in Sweden. In addition, the level of economic inequality has also increased. Based on self-rated health (SRH), we report a clear disparity between low and high SES and subjective social class (SSS), where higher SES and SSS are associated with better SRH. We observe a stronger association between SRH and reported present SSS (i.e., subjective social class aimed at capturing current situation) than between SRH and reported childhood SSS (i.e., subjective social class focusing on the situation when growing up). We show that the annual marginal effect of SES is not increasing but instead contributes with a stable annual contribution on SRH. Interestingly, the annual effect of education on SRH was substantially attenuated when adjusting for income, whereas the effect of income on SRH was only moderately different when adjusting for education. Potential mechanisms and remedies are discussed.

Konferensbidrag (refereegranskat)abstract
- This work combines fiber optic sensors with additive manufacturing to enable integration of temperature and strain sensors in metal components. In this paper, we present a fiber optic sensor network integrated in press hardening tools to monitor the contact between the tool and the metal sheet during forming operation. The tools are manufactured through metal powder bed fusion using laser melting processes (PBF-SLM), after which the tools are prepared for sensor integration. A demonstrator press hardening tool with integrated fiber optic sensors was heated using an electric heat foil and the sensor measurements was compared to a thermal simulation model. The sensor technology is based on Fiber Bragg Gratings (FBGs), integrated at several positions along the optical fiber. FBGs are in-fiber sensors that are multiplexed. lt is possible to place hundreds of FBG sensors along one single fiber, thus allowing for quasidistributed sensing of temperature or strain. The optical fiber itself can be less than 100 micrometer in diameter, allowing for sensing at several points in a minimally invasive way, when integrated in a tool or component.

- Objective: To describe the effects of switching treatment from ongoing first-line injectable therapies to rituximab on inflammatory activity measured by MRI and levels of CSF neurofilament light chain (CSF-NFL) in a cohort of patients with clinically stable relapsing-remitting multiple sclerosis (RRMS).Method: Seventy-five patients with clinically stable RRMS treated with the first-line injectables interferon-β (IFN-β) and glatiramer acetate (GA) at 3 Swedish centers were switched to rituximab in this open-label phase II multicenter study. After a run-in period of 3 months, 2 IV doses of 1,000 mg rituximab were given 2 weeks apart followed by repeated clinical assessment, MRI, and CSF-NFL for 24 months.Results: The mean cumulated number of gadolinium-enhancing lesions per patient at months 3 and 6 after treatment shift to rituximab was reduced compared to the run-in period (0.028 vs 0.36, p = 0.029). During the first year after treatment shift, the mean number of new or enlarged T2 lesions per patient was reduced (0.01 vs 0.28, p = 0.004) and mean CSF-NFL levels were reduced by 21% (p = 0.01).Conclusions: For patients with RRMS, a treatment switch from IFN or GA to rituximab is associated with reduced inflammatory activity measured by MRI and CSF-NFL.Classification of evidence: This study provides Class IV evidence that rituximab has an equal or superior effect in reducing inflammatory activity in RRMS measured by MRI and CSF-NFL compared to first-line injectables during the first year after treatment shift.
