- Mental health problems are increasing among children and adolescents. School-based mindfulness interventions are gaining popularity worldwide and may be a way to decrease depression and anxiety symptoms in students. However, before introducing large-scale mindfulness interventions in school settings, more research is needed on feasible, easily applicable practices that are possible to fit in the school schedule. In this controlled intervention study, a total of 1399 students aged 9-16 were included. The 10-week classroom-based mindfulness intervention comprised daily, brief mindfulness sessions led by schoolteachers or via audio files. Symptoms of depression and anxiety were evaluated with Beck scales prior to and after the intervention. In addition to whole group analyses, subgroup analyses on age, sex as well as mode of delivery were performed. ClinicalTrials.gov ID: NCT03327714. No significant differences between the intervention and control group in change of depression or anxiety symptoms after the intervention were detected. However, the subgroup of students who received teacher-led mindfulness sessions (16%) had a significant decrease of depression and anxiety symptoms after 10 weeks compared to those who received the sessions via audio files. Brief mindfulness sessions on daily basis did not have any detectable overall effect on depression and anxiety symptoms among schoolchildren. Our findings do not support an introduction of large-scale mindfulness interventions in schools although the potential influence of mode of delivery needs to be further examined.Clinical trial registration: The study was registered at ClinicalTrials.gov (identifier: NCT03327714).

- Background: Patients with squamous cell skin cancer (SCC) have an excellent prognosis but second primary cancers (SPCs) weaken survival prospects. Family history is a known risk factor for cancer but whether it is a risk factor for SPC in patients with SCC is not known. Objectives: To quantify the risk of family history on SPCs in patients with SCC and estimate survival probabilities of patients with SPCs depending on family history. Methods: With 13 945 histologically verified SCCs, relative risks (RRs) were estimated for family history using a generalized regression model. For survival analysis, hazard ratios (HRs) were assessed using a multivariable Cox proportional-hazards model. Results: Family history of invasive SCC increased risk of second invasive SCC [RR = 42·92, 95% confidence interval (CI) 33·69–50·32] compared with risk without family history (RR 19·12, 95% CI 17·88–21·08). Family history of any nonskin cancer in invasive SCC increased risk of the same cancers to be diagnosed as SPC (RRFH = 1·48, 95% CI 1·35–1·61 vs. RRno FH = 1·40, 95% CI 1·32–1·48); significant increases were observed for seven different nonskin cancers. Most results were replicated for in situ SCC. SPC was deleterious for survival irrespective of family history; HR for patients with SPC was 4·28 (95% CI 3·83–4·72) vs. those without SPC (1·04). Conclusions: Family history of nonskin cancer was associated with approximately a doubling of risk for SPCs in patients with SCC. SPC increases the death rate in patients with SCC 3–4 times, irrespective of family history. Taking family history into account at SCC diagnosis may help prevention or early detection of SPCs. What's already known about this topic? Second primary cancers (SPCs) are frequently diagnosed in patients with invasive and in situ squamous cell carcinoma (SCC); some epidemiological studies suggest a link to immune dysfunction. Family history of cancer is a risk factor for practically all first primary cancers but whether it also influences risk of SPCs in patients with SCC is not known. The possible influence of family history on survival in patients with SCC remains to be established.

Tidskriftsartikel (refereegranskat)abstract
- Background: Few longitudinal studies investigate predictors of substance use incidence among immigrants. The current study describes substance use disorders in immigrants to Sweden, focusing on drinking culture in the country of origin and socioeconomic status (SES), and how these intersect with generational status to influence risk. Methods: Using pseudonymized Swedish population registry data, we track onset of alcohol use disorder and drug use disorder in a longitudinal study of 815,778 first-generation immigrants and 674,757 second-generation immigrants from 64 countries over a 6-year period. Cox regression analysis estimated risks of alcohol and drug use disorders in second-generation immigrants compared to first-generation, and moderation analyses assessed interactions of generational status with country-of-origin per capita alcohol consumption and SES. Results: Immigrants and second-generation immigrants originating from countries with high levels of alcohol consumption had higher risks for alcohol and drug use disorders. Immigrants with high SES had lower risks for alcohol and drug use disorders. The interaction between generational status and country-of-origin alcohol consumption was significant for drug use disorder (not for alcohol use disorder), with drug use disorder risk for second-generation immigrants being highest for those from countries with the lowest level of country-of-origin per capita alcohol consumption. The interaction between generational status and SES was significant for alcohol use disorder, with low-SES second-generation immigrants showing markedly higher risk than first-generation immigrants with comparable SES. Conclusions: Among immigrants in Sweden, second-generation immigrants are at increased risk of developing alcohol and drug use disorders, particularly if they have lower SES. Policy and community attention to these high-risk subgroups in immigrant communities is warranted.

Does neighborhood alcohol availability moderate the impact of familial liability and marital status on risk for alcohol use disorders? A Swedish national study
- 2020
-

- Objective: The purpose of this study was to determine whether ease of access to alcohol at the neighborhood level moderates the impact of familial liability and marital status on risk for alcohol use disorder (AUD). Method: Individuals in Sweden were divided into those residing in a neighborhood with (n = 14.1%) versus without (n = 85.9%) an alcohol outlet (bars/nightclubs or government stores). AUD was detected through national medical, legal, and pharmacy registries. Using an additive model predicting AUD registration over 5 years in 1,624,814 individuals, we tested for interactions between the presence of outlets in the individuals’ neighborhoods and familial risk for external-izing syndromes and marital status. Results: In both males and females, we found positive and significant interactions in the prediction of AUD between the presence versus absence of a nearby alcohol outlet with (a) familial risk and (b) single and divorced versus married status. Similar but nonsignificant interactions were seen between nearby outlets and widowed versus married status. These results changed little when all cases with prior AUD were removed from the sample. For males, most of the interaction arose from the proximity of bars/nightclubs, whereas for females the results varied across different kinds of outlets. Conclusions: Environments that provide easy access to alcohol augment the impact of a range of risk factors for AUD, especially familial vulnerability and the reduced social constraints associated with single, divorced, and widowed marital status.

Tidskriftsartikel (refereegranskat)abstract
- Background The mortality in individuals with a family history of heart failure (HF) has not been determined. This nationwide sib-pair study aimed to determine mortality in individuals with a sibling affected with HF. Methods Sib-pairs were linked using the Swedish Multi-Generation Register, the Hospital Discharge Register and the Cause of Death Register for the period 1987–2012. Families with cardiomyopathy or congenital heart disease were excluded. Mortality hazard ratios (HRs) were calculated for siblings of individuals who had been diagnosed with HF compared with siblings of individuals unaffected by HF as the reference group. Similar analyses were made for spouses. HRs were determined for overall mortality, cardiovascular mortality, and death of unknown cause. Results Among siblings, the adjusted HR for overall mortality was 1.21 (95% CI 1.18–1.25). This risk remained (HR = 1.19, 95% CI 1.15–1.23) also among subjects without HF themselves. The adjusted HRs for cardiovascular mortality and death of unknown cause were 1.39 (95% CI 1.32–1.45) and 1.58 (95% CI 1.29–1.95), respectively. The mortality risk associations with spousal HF were all minimal, with an overall mortality HR of 1.02 (1.01–1.02). Early sibling age of onset of HF

Life is pain : Fibromyalgia as a nexus of multiple liability distributions
- 2023

- Fibromyalgia is a complex disease of unclear etiology that is complicated by difficulties in diagnosis, treatment, and clinical heterogeneity. To clarify this etiology, healthcare-based data are leveraged to assess the influences on fibromyalgia in several domains. Prevalence is less than 1% of females in our population register data, and about 1/10th that in males. Fibromyalgia often presents with co-occurring conditions including back pain, rheumatoid arthritis, and anxiety. More comorbidities are identified with hospital-associated biobank data, falling into three broad categories of pain-related, autoimmune, and psychiatric disorders. Selecting representative phenotypes with published genome-wide association results for polygenic scoring, we confirm genetic predispositions to psychiatric, pain sensitivity, and autoimmune conditions show associations with fibromyalgia, although these may differ by ancestry group. We conduct a genome-wide association analysis of fibromyalgia in biobank samples, which did not result in any genome-wide significant loci; further studies with increased sample size are necessary to identify specific genetic effects on fibromyalgia. Overall, fibromyalgia appears to have strong clinical and likely genetic links to several disease categories, and could usefully be understood as a composite manifestation of these etiological sources.
