1.	Fang, Fang, et al. (författare) Risk of infection-related cancers after the loss of a child : a follow-up study in Sweden 2011 Ingår i: Cancer Research. - Philadelphia, USA : American Association for Cancer Research. - 0008-5472 .- 1538-7445. ; 71:1, s. 116-22 Tidskriftsartikel (refereegranskat)abstract It is unknown whether severe emotional stress due to loss of a child influences the risk of cancers susceptible to immune modulation such as infection-related cancers. We conducted a historic cohort study in 1990 to 2004 on the basis of the Swedish Multi-Generation Register including 4,687,073 parents. Death of a child was identified through the Causes of Death Register. Poisson regression was used to derive the relative risks (RR) and 95% confidence intervals (CI) of infection-related cancers, comparing the incidence rates of parents who lost a child with those who never lost a child. A total of 101,306 parents (2%) had lost a child during follow-up, among whom 1,608 subsequently developed infection-related cancers. After adjustment for age, sex, calendar year, educational level, and civil status, the overall RR of 14 cancers studied was 1.07 (95% CI: 1.02-1.12). Parents who lost a child were particularly at a higher risk for cancers potentially associated with human papilloma virus (HPV) infection such as cervical cancer (RR: 1.46; 95% CI: 1.17-1.80). Higher RRs for most cancers were obtained within 5 years after child loss and excess risk for liver and stomach cancers was confined to that period. No association was observed for lymphoma and nonmelanoma skin cancer at any time point after child loss. Although potential confounding by unmeasured factors cannot be ruled out, our findings lend support to the hypothesis that severe life stressors, such as child loss, may raise the risk for several, chiefly HPV-related, cancers.

(författare) Optimal communication associated with lower risk of acute traumatic stress after lung cancer diagnosis 2022 Ingår i: Supportive Care in Cancer. - : Springer. - 0941-4355 .- 1433-7339. ; 30:1, s. 259-269 Tidskriftsartikel (refereegranskat)abstract Purpose: The aim of this study was to assess the role of the patient's background and perceived healthcare-related factors in symptoms of acute stress after lung cancer diagnosis.Methods: The study population consisted of 89 individuals referred for diagnostic work-up at Landspitali National University Hospital in Iceland and subsequently diagnosed with lung cancer. Before diagnosis, the patients completed questionnaires on sociodemographic characteristics, pre-diagnostic distress (Hospital Anxiety and Depression Scale), social support, and resilience. At a median of 16 days after diagnosis, the patients reported symptoms of acute stress on the Impact of Event Scale-Revised (IES-R) and experience of communication and support from healthcare professionals and family during the diagnostic period.Results: Patients were on average 68 years and 52% reported high levels of post-diagnostic acute stress (IES-R > 23) while 24% reported symptoms suggestive of clinical significance (IES-R > 32). Prior history of cancer (beta = 6.7, 95% CI: 0.1 to 13.3) and pre-diagnostic distress were associated with higher levels of post-diagnostic acute stress (beta = 8.8, 95% CI: 2.7 to 14.9), while high educational level (beta = - 7.9, 95% CI: - 14.8 to - 1.1) was associated with lower levels. Controlling for the abovementioned factors, the patients' perception of optimal doctor-patient (beta = - 9.1, 95% CI: - 14.9 to - 3.3) and family communication (beta = - 8.6, 95% CI: - 14.3 to - 2.9) was inversely associated with levels of post-diagnostic acute stress after lung cancer diagnosis.Conclusions: A high proportion of patients with newly diagnosed lung cancer experience high levels of acute traumatic stress of potential clinical significance. Efforts to improve doctor-patient and family communication may mitigate the risk of these adverse symptoms.
3.	Hardardottir, Hronn, et al. (författare) Psychobiological stress response to a lung cancer diagnosis : a prospective study of patients in Iceland and Sweden 2023 Ingår i: Acta Oncologica. - : Taylor & Francis. - 0284-186X .- 1651-226X. ; 62:10, s. 1338-1347 Tidskriftsartikel (refereegranskat)abstract Background: A diagnostic work-up leading to a lung cancer diagnosis is a severely stressful experience that may impact tumor progression. Yet, prospective data are scarce on psychological and biological components of stress at the time of lung cancer diagnosis. The aim of this study was to assess pre-to-post diagnosis change in psychological distress and urinary excretion of catecholamines in patients with suspected lung cancer.Methods: Participants were 167 patients within the LUCASS study, recruited at referral for suspected lung cancer to University Hospitals in Iceland and Sweden. Patients completed questionnaires on perceived distress (Hospital Anxiety and Depression Scale, HADS) before and after diagnosis of lung cancer or a non-malignant origin. A subpopulation of 85 patients also provided overnight urine for catecholamine analysis before and at a median of 24 days after diagnosis but before treatment.Results: A lung cancer diagnosis was confirmed in 123 (73.7%) patients, with a mean age of 70.1 years. Patients diagnosed with lung cancer experienced a post-diagnosis increase in psychological distress (p = 0.010), while patients with non-malignant lung pathology showed a reduction in distress (p = 0.070). Both urinary epinephrine (p = 0.001) and norepinephrine (p = 0.032) levels were higher before the diagnosis among patients eventually diagnosed with lung cancer compared to those with non-malignant lung pathology. We observed indications of associations between pre-to-post diagnosis changes in perceived distress and changes in urinary catecholamine levels.Conclusion: Receiving a lung cancer diagnosis is associated with an increase in psychological distress, while elevated catecholamine levels are evident already before lung cancer diagnosis.

(författare) Childhood Bereavement and Lower Stress Resilience in Late Adolescence 2018 Ingår i: Journal of Adolescent Health. - : Elsevier. - 1054-139X .- 1879-1972. ; 63:1, s. 108-114 Tidskriftsartikel (refereegranskat)abstract PURPOSE: Although childhood traumatic experiences are recognized as important determinants for adolescent psychiatric health in general, our objective was to explore the specific influence of childhood bereavement on the stress resilience development trajectory.METHODS: In this national register-based cohort study, we identified 407,639 men born in Sweden between 1973 and 1983, who underwent compulsory military enlistment examinations in late adolescence, including measures of psychological stress resilience. We defined exposure as loss of a first-degree family member in childhood, and estimated relative risk ratios (RRRs) for reduced (moderate or low), compared with high, stress resilience with 95% confidence intervals (CIs) using multinomial logistic regression.RESULTS: Loss of a parent or sibling in childhood conferred a 49% increased risk of subsequent low stress resilience (RRR, 1.49, 95% CI, 1.41-1.57) and an 8% increased risk of moderate stress resilience (RRR, 1.08, 95% CI, 1.03-1.13) in late adolescence. There was also a graded increase in risk with increasing age at loss; teenagers were at higher risk for low resilience (RRR, 1.64, 95% CI, 1.52-1.77) than children aged 7-12 (RRR, 1.47, 95% CI, 1.34-1.61) and ≤6 years (RRR, 1.16 95% CI, 1.02-1.32). The excess risk was observed for all causes of death, including suicide and unexpected deaths as well as deaths due to other illnesses. The associations remained after exclusion of parents with a history of hospitalization for psychiatric diagnoses.CONCLUSIONS: The long-term consequences of childhood bereavement may include lower stress resilience in late adolescence.

(författare) Psychiatric comorbidities in women with cardiometabolic conditions with and without ADHD : a population-based study 2023 Ingår i: BMC Medicine. - : BioMed Central (BMC). - 1741-7015. ; 21:1 Tidskriftsartikel (refereegranskat)abstract BACKGROUND: Leveraging a large nationwide study of Icelandic women, we aimed to narrow the evidence gap around female attention-deficit/hyperactivity disorder (ADHD) and cardiometabolic comorbidities by determining the prevalence of obesity, hypertension, type 2 diabetes, and cardiovascular diseases among women with ADHD and examine the association between cardiometabolic conditions and co-occurring ADHD with anxiety and mood disorders, alcoholism/substance use disorder (SUD), self-harm, and suicide attempts.METHODS: We conducted a cross-sectional analysis of the nationwide, all-female, population-based SAGA Cohort Study (n = 26,668). To ascertain diagnoses and symptoms, we used self-reported history of ADHD diagnoses, selected cardiometabolic conditions and psychiatric disorders, and measured current depressive, anxiety, and PTSD symptoms through appropriate questionnaires (PHQ-9, GAD-7, and PCL-5). We calculated age-adjusted prevalences of cardiometabolic conditions by women's ADHD status and estimated adjusted prevalence ratios (PR) and 95% confidence intervals (CI), using modified Poisson regression models. Similarly, we assessed the association of cardiometabolic conditions and co-occurring ADHD with current psychiatric symptoms and psychiatric disorders, using adjusted PRs and 95% CIs.RESULTS: We identified 2299 (8.6%) women with a history of ADHD diagnosis. The age-adjusted prevalence of having at least one cardiometabolic condition was higher among women with ADHD (49.5%) than those without (41.7%), (PR = 1.19, 95% CI 1.14-1.25), with higher prevalence of all measured cardiometabolic conditions (myocardial infarctions (PR = 2.53, 95% CI 1.83--3.49), type 2 diabetes (PR = 2.08, 95% CI 1.66-2.61), hypertension (PR = 1.23, 95% CI 1.12-1.34), and obesity (PR = 1.18, 95% CI 1.11-1.25)). Women with cardiometabolic conditions and co-occurring ADHD had, compared with those without ADHD, substantially increased prevalence of (a) all measured mood and anxiety disorders, e.g., depression (PR = 2.38, 95% CI 2.19-2.58), bipolar disorder (PR = 4.81, 95% CI 3.65-6.35), posttraumatic stress disorder (PR = 2.78, 95% CI 2.52-3.07), social phobia (PR = 2.96, 95% CI 2.64-3.32); (b) moderate/severe depressive, anxiety, and PTSD symptoms with PR = 1.76 (95% CI 1.67-1.85), PR = 1.97 (95% CI 1.82-2.12), and PR = 2.01 (95% CI 1.88-2.15), respectively; (c) alcoholism/SUD, PR = 4.79 (95% CI 3.90-5.89); and (d) self-harm, PR = 1.47 (95% CI 1.29-1.67) and suicide attempts, PR = 2.37 (95% CI 2.05-2.73).CONCLUSIONS: ADHD is overrepresented among women with cardiometabolic conditions and contributes substantially to other psychiatric comorbidities among women with cardiometabolic conditions.

7.	Thorarinsdottir, Kristjana, et al. (författare) Reducing Intrusive Memories of Childhood Trauma Using a Visuospatial Intervention: Case Study in Iceland 2021 Ingår i: JMIR Formative Research. - : JMIR Publications. - 2561-326X. ; 5:11, s. e29873- Tidskriftsartikel (refereegranskat)abstract Background: Additional interventions are needed for survivors of psychological trauma because of several barriers to and limitations of existing treatment options (eg, need to talk about the trauma in detail). Case studies are an important step in exploring the development of novel interventions, allowing detailed examination of individual responses to treatment over time. Here, we present a case study that aims to test a novel intervention designed to disrupt memory reconsolidation, taking a single-symptom approach by focusing on intrusive memories of a traumatic event.Objective: This study aims to examine a novel brief cognitive intervention to reduce the number of intrusive memories of trauma in an Icelandic setting and to extend previous studies by examining long-term effects for up to 3 months. The intervention was guided by a clinical psychologist and comprised a brief memory reminder, followed by Tetris gameplay with mental rotation, targeting one memory at a time in each session.Methods: This was a single case study in Iceland with a woman in her 50s (drawn from an epidemiological study of trauma) with subthreshold posttraumatic stress disorder and a diagnosis of obsessive-compulsive disorder and social anxiety disorder. The participant had four different intrusive memories from a traumatic event that happened in her childhood. The primary outcome was the change in the number of intrusive memories from baseline to intervention phase and to follow-ups. The number of intrusions was monitored in a daily diary for 4 weeks preintervention, 8 weeks during the intervention, and 1 week at 1-month and 3-month follow-ups. Intrusions were targeted one by one over six intervention sessions, creating four repetitions of an AB design (ie, length of baseline A and intervention phase B varied for each memory). We examined changes in both the total number of intrusions (summed across all four memories) and individually for each memory. In addition, we explored whether having fewer intrusive memories would have an impact on functioning, posttraumatic stress, and depression or anxiety symptoms.Results: The total number of intrusions per week was 12.6 at baseline, 6.1 at the intervention phase (52% reduction from baseline), 3.0 at the 1-month follow-up (76% reduction), and 1.0 at the 3-month follow-up (92% reduction). Reductions in the symptoms of posttraumatic stress and depression were observed postintervention. Sleep, concentration, stress, and functioning improved. The participant considered the gameplay intervention acceptable and helpful in that she found that the memories disappeared while she was playing.Conclusions: This guided brief cognitive intervention reduced the number of intrusive memories over the intervention phase and follow-ups. The brief memory reminder was well tolerated, removing the need to discuss trauma in detail. The next steps require an extension to more cases and exploring remote delivery of the intervention.

10.	Arnberg, Filip K, 1981-, et al. (författare) Psychiatric disorders and suicide attempts in Swedish survivors of the 2004 southeast Asia tsunami : a 5 year matched cohort study 2015 Ingår i: The Lancet Psychiatry. - Stockholm : Karolinska Institutet, Dept of Medical Epidemiology and Biostatistics. - 2215-0366 .- 2215-0374. ; 2:9, s. 817-824 Tidskriftsartikel (refereegranskat)abstract BackgroundSurvivors of natural disasters are thought to be at an increased risk of psychiatric disorders, however the extent of this risk, and whether it is linked to pre-existing psychopathology, is not known. We aimed to establish whether Swedish survivors of tsunamis from the 2004 Sumatra–Andaman earthquake had increased risks of psychiatric disorders and suicide attempts 5 years after repatriation.MethodsWe identified Swedish survivors repatriated from southeast Asia (8762 adults and 3742 children) and 864 088 unexposed adults and 320 828 unexposed children matched for sex, age, and socioeconomic status. We retrieved psychiatric diagnoses and suicide attempts from the Swedish patient register for the 5 years after the tsunami (from Dec 26, 2004, to Jan 31, 2010) and estimated hazard ratios (HRs), then adjusted for pre-tsunami psychiatric disorders, and, for children, for parental pre-tsunami disorders.Findings Exposed adults were more likely than unexposed adults to receive any psychiatric diagnosis (547 [6.2%] vs 47 734 [5.5%]; adjusted HR 1.21, 95% CI 1.11–1.32), particularly stress-related disorders (187 [2.1%] vs 8831 [1.0%]; 2.27, 1.96–2.62) and suicide attempts (38 [0.43%] vs 2752 [0.32%]; 1.54, 1.11–2.13), but not mood or anxiety disorders. Risk of psychiatric diagnoses did not differ between exposed and unexposed children and adolescents (248 [6.6] vs 22 081 [6.9%]; 0.98, 0.86–1.11), although exposed children and adolescents had a higher risk for suicide attempts with uncertain intent (1.43; 1.01–2.02) and stress-related disorders (1.79; 1.30–2.46), mainly during the first 3 months after the tsunami.InterpretationThe 2004 tsunami was, independently of previous psychiatric morbidity, associated with an increased risk of severe psychopathology, mainly stress-related disorders and suicide attempts, in children and adults. Survivors of natural disasters should be targeted with early interventions and active long-term follow-up to prevent, detect, and alleviate psychiatric disorders that might follow.

12.	Asgeirsdottir, Hildur Guony, et al. (författare) Low preparedness before the loss of a wife to cancer and the widower's chronic pain 4-5 years later-a population-based study 2013 Ingår i: Psycho-Oncology. - : Wiley. - 1099-1611 .- 1057-9249. ; 22:12, s. 2763-2770 Tidskriftsartikel (refereegranskat)abstract ObjectiveThe focus of this study was on the impact of spousal loss on the development of chronic pain thereafter. More specifically, the aim was to investigate the effect of experiencing low preparedness before a wife's death and the widower's chronic pain 4-5 years after loss. MethodsIn a population-based study in the years 2004-2005, anonymous questionnaires were sent out to 907 men in Sweden who had lost a wife to cancer in 2000 and 2001. The questionnaires contained questions on the man's preparedness for his wife's death and his physical and psychological health at follow-up. ResultsAltogether, 691 out of 907 questionnaires were retrieved (76%). Younger widowers (38-61 years old) with a low degree of preparedness for their wife's death had an increased risk of experiencing symptoms of chronic pain (odds ratio 6.67; 2.49-17.82) 4-5 years after loss. The same results did not apply for older widowers (62-80 years old) (odds ratio 0.81; 0.32-2.05). Widowers who experienced chronic pain were at an increased risk for psychological morbidity, depression (relative risk [RR] 2.21; 1.31-3.74), anxiety (RR 2.11; 1.33-3.37), and sleep disorders (RR 2.19; 1.30-3.69). ConclusionOur data suggest that low preparedness for a wife's death may increase risk of chronic pain among younger widowers 4-5 years after loss. In addition, we found comorbidity between psychological symptoms and chronic pain among widowers. These findings call for studies on possible mechanisms in the association between low preparedness and morbidity and on how to increase preparedness for a wife's death to cancer.

13.	Bjork Thordardottir, Edda, et al. (författare) Mortality and major disease risk among migrants of the 1991-2001 Balkan wars to Sweden : A register-based cohort study 2020 Ingår i: PLoS Medicine. - : Public Library of Science (PLoS). - 1549-1277 .- 1549-1676. ; 17:12 Tidskriftsartikel (refereegranskat)abstract Background: In recent decades, millions of refugees and migrants have fled wars and sought asylum in Europe. The aim of this study was to quantify the risk of mortality and major diseases among migrants during the 1991-2001 Balkan wars to Sweden in comparison to other European migrants to Sweden during the same period.Methods and findings: We conducted a register-based cohort study of 104,770 migrants to Sweden from the former Yugoslavia during the Balkan wars and 147,430 migrants to Sweden from 24 other European countries during the same period (1991-2001). Inpatient and specialized outpatient diagnoses of cardiovascular disease (CVD), cancer, and psychiatric disorders were obtained from the Swedish National Patient Register and the Swedish Cancer Register, and mortality data from the Swedish Cause of Death Register. Adjusting for individual-level data on sociodemographic characteristics and emigration country smoking prevalence, we used Cox regressions to contrast risks of health outcomes for migrants of the Balkan wars and other European migrants. During an average of 12.26 years of follow-up, being a migrant of the Balkan wars was associated with an elevated risk of being diagnosed with CVD (HR 1.39, 95% CI 1.34-1.43, p < 0.001) and dying from CVD (HR 1.45, 95% CI 1.29-1.62, p < 0.001), as well as being diagnosed with cancer (HR 1.16, 95% CI 1.08-1.24, p < 0.001) and dying from cancer (HR 1.27, 95% CI 1.15-1.41, p < 0.001), compared to other European migrants. Being a migrant of the Balkan wars was also associated with a greater overall risk of being diagnosed with a psychiatric disorder (HR 1.19, 95% CI 1.14-1.23, p < 0.001), particularly post-traumatic stress disorder (HR 9.33, 95% CI 7.96-10.94, p < 0.001), while being associated with a reduced risk of suicide (HR 0.68, 95% CI 0.48-0.96, p = 0.030) and suicide attempt (HR 0.57, 95% CI 0.51-0.65, p < 0.001). Later time period of migration and not having any first-degree relatives in Sweden at the time of immigration were associated with greater increases in risk of CVD and psychiatric disorders. Limitations of the study included lack of individual-level information on health status and behaviors of migrants at the time of immigration.Conclusions: Our findings indicate that migrants of the Balkan wars faced considerably elevated risks of major diseases and mortality in their first decade in Sweden compared to other European migrants. War migrants without family members in Sweden or with more recent immigration may be particularly vulnerable to adverse health outcomes. Results underscore that persons displaced by war are a vulnerable group in need of long-term health surveillance for psychiatric disorders and somatic disease.

(författare) Long-lasting improvements in health-related quality of life among women with chronic pain, following multidisciplinary rehabilitation 2018 Ingår i: Disability and Rehabilitation. - : Informa UK Limited. - 0963-8288 .- 1464-5165. ; 40:15, s. 1764-1772 Tidskriftsartikel (refereegranskat)abstract Purpose:To determine whether observed health-related quality-of-life improvements after four-week traditional multidisciplinary pain management program and additional neuroscience education and mindfulness-based cognitive therapy for chronic pain are sustained at six-month follow-up.Method:This observational longitudinal follow-up study, with complete follow-up of 75 women, 61.5% of initial traditional approach group (treated 2001-2005) and 56 (62.2%) receiving the new approach (treated 2006-2009). Pain intensity and quality of life were measured at baseline and six months after interventions. Analysis of variance (ANOVA) and paired samples t-tests were used for statistical analysis.Results:Both groups showed sustained improvements in pain intensity (traditional approach = -10.6 [p < 0.001]; new approach = -14.5 [p < 0.001]) and quality of life (traditional approach = 6.4 [p < 0.001]; new approach = 6.9 [p < 0.001]). Sleep was not sustained among traditional approach group (change = 2.4 [p = 0.066]), whereas all other domains among both groups were sustained. Significant decline was observed from discharge to six month among both groups with the exception of the sleep domain among the traditional approach group, pain intensity among the new approach and financial status among both groups. No baseline differences were revealed between responders and nonresponders.Conclusions:Multidisciplinary interventions for women with chronic pain conditions improved quality of life and pain intensity with lasting improvements observed half a year after treatment completion.

(författare) Health-related quality of life improvements among women with chronic pain : comparison of two multidisciplinary interventions 2016 Ingår i: Disability and Rehabilitation. - : Informa UK Limited. - 0963-8288 .- 1464-5165. ; 38:9, s. 828-836 Tidskriftsartikel (refereegranskat)abstract Purpose: To measure the effect of 4 weeks traditional multidisciplinary pain management program (TMP) versus neuroscience education and mindfulness-based cognitive therapy (NEM) on quality of life (HRQL) among women with chronic pain. Method: This observational longitudinal cohort study conducted in an Icelandic rehabilitation centre included 122 women who received TMP, 90 receiving NEM, and 57 waiting list controls. Pain intensity (visual analogue scale) and HRQL (Icelandic Quality of Life scale) were measured before and after interventions. ANOVA and linear regression were used for comparisons. Results: Compared with controls we observed statistically significant changes in pain intensity (p < 0.001) and HRQL (p < 0.001) among women receiving both interventions, while NEM participants reported significant improvements in sleep (8.0 versus 4.4 in TMP; p = 0.008). Head to head comparison between study groups revealed that pain intensity improved more among TMP participants (21.8 versus 17.2 mm; p = 0.013 adjusted). Women with low HRQL at baseline improved more than those with higher HRQL (mean TMP = 13.4; NEM = 12.9 if HRQL <= 35 versus mean TMP = 6.6 and NEM = 7.8 if HQRL > 35). Conclusions: Our non-randomized study suggests that both NEM and TMP programs improve pain and HRQL among women with chronic pain. Sleep quality showed more improvements in NEM while pain intensity in TMP. Longer-term follow-ups are needed to address whether improvements sustain. Implications for Rehabilitation Chronic pain is a debilitating condition affecting quality of life and restricting societal participation. Intensive multidisciplinary bio-psycho-social rehabilitation is essential for this patient group. This study shows improvement in health-related quality of life and pain intensity following such rehabilitation. Emphasizing mindfulness based cognitive therapy and neuroscience patient education improves sleep to more extend than more traditional approach.

(författare) Sexually transmitted infections after bereavement - a population-based cohort study 2016 Ingår i: BMC Infectious Diseases. - London, England : BioMed Central. - 1471-2334. ; 16 Tidskriftsartikel (refereegranskat)abstract Background: Loss of a loved one has consistently been associated with various health risks. Little is however known about its relation to sexually transmitted infections (STIs).Methods: We conducted a population-based cohort study during 1987-2012 using the Swedish Multi-Generation Register, including 3,002,209 women aged 10-44 years. Bereavement was defined as death of a child, parent, sibling or spouse (N = 979,579, 33 %). STIs were defined as hospital visits with an STI as main or secondary diagnosis. Poisson regression and negative binomial regression were used to estimate incidence rate ratios (IRRs) and 95 % confidence intervals (CIs) of STIs, comparing incidence rates of women who had experienced loss to those who had not.Results: Bereaved women were at significantly higher risk of nearly all STIs studied. The relative risk of any STI was highest during the first year after loss (IRR: 1.45, 95 % CI: 1.27-1.65) and predominantly among women with subsequent onset of psychiatric disorders after bereavement (IRR: 2.61, 95 % CI: 2.00-3.34). Notably, a consistent excess risk, persisting for over five years, was observed for acute salpingitis (IRR: 1.28, 95 % CI: 1.13-1.44), a severe complication of bacterial STIs.Conclusion: These data suggest that women who have experienced bereavement are at increased risk of STIs.
17.	Bränn, Emma, et al. (författare) Bidirectional association between autoimmune disease and perinatal depression : a nationwide study with sibling comparison 2024 Ingår i: Molecular Psychiatry. - : Springer Nature. - 1359-4184 .- 1476-5578. ; 29:3, s. 602-610 Tidskriftsartikel (refereegranskat)abstract Although major depression, characterized by a pro-inflammatory profile, genetically overlap with autoimmune disease (AD) and the perinatal period involve immune system adaptations and AD symptom alterations, the bidirectional link between perinatal depression (PND) and AD is largely unexplored. Hence, the objective of this study was to investigate the bidirectional association between PND and AD. Using nationwide Swedish population and health registers, we conducted a nested case-control study and a matched cohort study. From 1,347,901 pregnancies during 2001-2013, we included 55,299 incident PND, their unaffected full sisters, and 10 unaffected matched women per PND case. We identified 41 subtypes of AD diagnoses recorded in the registers and compared PND with unaffected population-matched women and full sisters, using multivariable regressions. Women with an AD had a 30% higher risk of subsequent PND (95% CI 1.2-1.5) and women exposed to PND had a 30% higher risk of a subsequent AD (95% CI 1.3-1.4). Comparable associations were found when comparing exposed women with their unaffected sisters (nested case-control OR: 1.3, 95% CI 1.2-1.5, matched cohort HR: 1.3, 95% CI 1.1-1.6), and when studying antepartum and postpartum depression. The bidirectional association was more pronounced among women without psychiatric comorbidities (nested case-control OR: 1.5, 95% CI 1.4-1.6, matched cohort HR: 1.4, 95% CI 1.4-1.5) and strongest for multiple sclerosis (nested case-control OR: 2.0, 95% CI 1.6-2.3, matched cohort HR: 1.8, 95% CI 1.0-3.1). These findings demonstrate a bidirectional association between AD and PND independent of psychiatric comorbidities, suggesting possibly shared biological mechanisms. If future translational science confirms the underlying mechanisms, healthcare providers need to be aware of the increased risk of PND among women with ADs and vice versa.

Little is known about the potential influence on the risk for self-injury of factors that could be clinically relevant to and modifiable by the health-care professionals involved in the care of the dying parent.METHODS: In a nationwide population-based anonymous study, 622 (73.1%) youths (aged 18-26) who, 6 to 9 years earlier at ages 13 to 16, had lost a parent to cancer answered study-specific questions about self-injury and factors related to the family and parental health care.RESULTS: Univariable analyses showed that the risk for self-injury was increased among cancer-bereaved youths who reported poor family cohesion the years before (relative risk [RR], 3.4, 95% confidence interval [CI], 2.5-4.6) and after the loss (RR, 3.3, 95% CI, 2.4-4.4), distrust in the health care provided to the dying parent (RR, 1.7, 95% CI, 1.2-2.4), perceiving poor health-care efforts to cure the parent (RR 1.5, 95% CI, 1.1-2.1) and poor efforts to prevent suffering (RR, 1.6, 95% CI, 1.1-2.4), that at least one of their parents had been depressed or had troubles in life (RR, 1.5, CI, 1.1-2.1) and believing 3 days before the loss that the treatment would probably cure the parent (RR, 1.6, CI, 1.1-2.3). In the total multivariable models, only poor family cohesion before and after the loss remained statistically significantly associated with self-injury.CONCLUSION: Poor family cohesion before and after the loss of a parent to cancer is associated with an increased risk of self-injury in teenage children.

(författare) Teenagers want to be told when a parent's death is near: A nationwide study of cancer-bereaved youths' opinions and experiences. 2015 Ingår i: Acta oncologica (Stockholm, Sweden). - 1651-226X .- 0284-186X. ; 54:6, s. 944-950 Tidskriftsartikel (refereegranskat)abstract Background. We aimed to investigate cancer-bereaved youths' opinions and experiences of being told about a parent's imminent death from cancer and of barriers to this communication. Material and methods. This nationwide population-based survey included 622/851 (73%) youths (aged 18-26) who at age 13-16, 6-9 years earlier had lost a parent to cancer. Results. In total 595 of 610 (98%) of the participants stated that teenage children should be informed when the parent's death was imminent (i.e. a matter of hours or days, not weeks). 59% stated that they themselves had been told this, 37% by the parents, 7% by parents and healthcare professionals together and 8% by professionals only. Frequent reasons for why the teenager and parents did not talk about imminent death before loss were that one (n = 106) or both (n = 25) of the parents together with the teenage child had pretended that the illness was not that serious, or that none of the parents had been aware that death was imminent (n = 80). Up to a couple of hours before the loss, 43% of participants had not realized that death was imminent. Conclusion. In this population-based study virtually all youth who at ages 13-16 had lost a parent to cancer afterwards stated that teenagers should be told when loss is near, i.e. a matter of hours or days, not weeks. Many stated that they had not been given this information and few were informed by professionals, with implications for future improvements in end-of-life care of patients with teenage children.

The Icelandic volcano Eyjafjallajökull exposed residents in southern Iceland to continuous ash fall for more than 5 weeks in spring 2010. This study was conducted during November 2010-March 2011, 6-9 months after the Eyjafjallajökull eruption.PARTICIPANTS: Adult (18-80 years of age) eruption-exposed South Icelanders (N=1148) and a control population of residents of Skagafjörður, North Iceland (N=510). The participation rate was 72%.MAIN OUTCOME MEASURES: Physical symptoms in the previous year (chronic), in the previous month (recent), General Health Questionnaire (GHQ-12) measured psychological morbidity.RESULTS: The likelihood of having symptoms during the last month was higher in the exposed population, such as; tightness in the chest (OR 2.5; 95% CI 1.1 to 5.8), cough (OR 2.6; 95% CI 1.7 to 3.9), phlegm (OR 2.1; 95% CI 1.3 to 3.2), eye irritation (OR 2.9; 95% CI 2.0 to 4.1) and psychological morbidity symptoms (OR 1.3; 95% CI 1.0 to 1.7). Respiratory symptoms during the last 12 months were also more common in the exposed population; cough (OR 2.2; 95% CI 1.6 to 2.9), dyspnoea (OR 1.6; 95% CI 1.1 to 2.3), although the prevalence of underlying asthma and heart disease was similar. Twice as many in the exposed population had two or more symptoms from nose, eyes or upper-respiratory tract (24% vs 13%, p<0.001); these individuals were also more likely to experience psychological morbidity (OR 4.7; 95% CI 3.4 to 6.5) compared with individuals with no symptoms. Most symptoms exhibited a dose-response pattern within the exposed population, corresponding to low, medium and high exposure to the eruption.CONCLUSIONS: 6-9 months after the Eyjafjallajökull eruption, residents living in the exposed area, particularly those closest to the volcano, had markedly increased prevalence of various physical symptoms. A portion of the exposed population reported multiple symptoms and may be at risk for long-term physical and psychological morbidity. Studies of long-term consequences are therefore warranted.

Respiratory health effects of exposure to PM and traffic pollutants are well documented, yet this is one of the first studies to investigate short-term health effects of ambient H 2S exposure. Objectives: The aim of this study was to investigate the associations between daily ambient levels of H 2S, PM 10, nitrogen dioxide (NO 2) and ozone (O 3), and the use of drugs for obstructive pulmonary diseases in adults in Iceland's capital area. Methods: The study period was 8 March 2006 to 31 December 2009. We used log-linear Poisson generalized additive regression models with cubic splines to estimate relative risks of individually dispensed drugs by air pollution levels. A three-day moving average of the exposure variables gave the best fit to the data. Final models included significant covariates adjusting for climate and influenza epidemics, as well as time-dependent variables. Results: The three-day moving average of H 2S and PM 10 levels were positively associated with the number of individuals who were dispensed drugs at lag 3-5, corresponding to a 2.0% (95% confidence interval [CI] 0.4, 3.6) and 0.9% (95% CI 0.1, 1.8) per 10μg/m 3 pollutant concentration increase, respectively. Conclusion: Our findings indicated that intermittent increases in levels of particle matter from traffic and natural sources and ambient H 2S levels were weakly associated with increased dispensing of drugs for obstructive pulmonary disease in Iceland's capital area. These weak associations could be confounded by unevaluated variables hence further studies are needed. © 2012 Elsevier Inc.

(författare) Increased respiratory morbidity associated with exposure to a mature volcanic plume from a large Icelandic fissure eruption. 2021 Ingår i: Nature Communications. - : Springer Science and Business Media LLC. - 2041-1723. ; 12:1 Tidskriftsartikel (refereegranskat)abstract The 2014-15 Holuhraun eruption in Iceland was the largest fissure eruption in over 200 years, emitting prodigious amounts of gas and particulate matter into the troposphere. Reykjavík, the capital area of Iceland (250km from eruption site) was exposed to air pollution events from advection of (i) a relatively young and chemically primitive volcanic plume with a high sulphur dioxide gas (SO2) to sulphate PM (SO42-) ratio, and (ii) an older and chemically mature volcanic plume with a low SO2/SO42- ratio. Whereas the advection and air pollution caused by the primitive plume were successfully forecast and forewarned in public advisories, the mature plume was not. Here, we show that exposure to the mature plume is associated with an increase in register-measured health care utilisation for respiratory disease by 23% (95% CI 19.7-27.4%) and for asthma medication dispensing by 19.3% (95% CI 9.6-29.1%). Absence of public advisories is associated with increases in visits to primary care medical doctors and to the hospital emergency department. We recommend that operational response to volcanic air pollution considers both primitive and mature types of plumes.

The aim of this study was to determine if exposure to extreme SO 2levels affected the health of individuals working at the eruption site. Methods During January‒March 2015, earth scientists, technicians, and law enforcement personnel who were about to work at the eruption site were invited to a respiratory health examination. Symptom reports and lung function measures, forced expiratory volume in one second (FEV 1) and forced vital capacity (FVC) were collected before and after an eruption site visit. Those with previous exposure (N=27) reported symptoms retrospectively. Results Altogether, 41 individuals were invited to participate, 32 underwent a clinical examination at a hospital respiratory health clinic (baseline); 27 reported symptoms during earlier visits to the eruption site (retrospective symptom reports), 17 were re-examined 1-6 days after visiting the eruption site (follow-up). All participants' lung function was within normal range both before and after exposure. At baseline, average FEV 1was 107.4% of predicted versus 106.6 at follow-up (P =0.82); average FVC was 107.0% of predicted at baseline versus 107.4% at follow-up (P=0.35). Eye and nasal irritation were more frequently reported during eruption site exposure by 24% versus 6% (P =0.37) for both. Conclusion Although "healthy-worker" effects cannot be excluded, our data indicate that SO 2exposure was associated with relatively mild and transient respiratory symptoms with no clinical signs of airway inflammation or airway obstruction.

(författare) Severe volcanic SO2 exposure and respiratory morbidity in the Icelandic population – a register study 2021 Ingår i: Environmental Health: A Global Access Science Source. - : Springer Science and Business Media LLC. - 1476-069X. ; 20 Tidskriftsartikel (refereegranskat)abstract Background: The Holuhraun volcanic eruption September 2014 to February 2015 emitted large amounts of sulfur dioxide (SO ). The aim of this study was to determine the association between volcanic SO gases on general population respiratory health some 250 km from the eruption site, in the Icelandic capital area. Methods: Respiratory health outcomes were: asthma medication dispensing (AMD) from the Icelandic Medicines Register, medical doctor consultations in primary care (PCMD) and hospital emergency department visits (HED) in Reykjavík (population: 215000) for respiratory disease from 1 January 2010 to 31 December 2014. The associations between daily counts of health events and daily mean SO concentration and high SO levels (24-h mean SO > 125 μg/m3) were analysed using generalized additive models. Results: After the eruption began, AMD was higher than before (129.4 vs. 158.4 individuals per day, p < 0.05). For PCMD and HED, there were no significant differences between the number of daily events before and after the eruption (142.2 vs 144.8 and 18.3 vs 17.5, respectively). In regression analysis adjusted for other pollutants, SO was associated with estimated increases in AMD by 0.99% (95% CI 0.39–1.58%) per 10 μg/m at lag 0–2, in PCMD for respiratory causes 1.26% (95% CI 0.72–1.80%) per 10 μg/m SO at lag 0–2, and in HED by 1.02% (95% CI 0.02–2.03%) per 10 μg/m SO at lag 0–2. For days over the health limit, the estimated increases were 10.9% (95% CI 2.1–19.6%), 17.2% (95% CI 10.0–24.4%) for AMD and PCMD. Dispensing of short-acting medication increased significantly by 1.09% (95% CI 0.49–1.70%), and PCMD for respiratory infections and asthma and COPD diagnoses and increased significantly by 1.12% (95% CI 0.54–1.71%) and 2.08% (1.13–3.04%). Conclusion: High levels of volcanic SO are associated with increases in dispensing of AMD, and health care utilization in primary and tertiary care. Individuals with prevalent respiratory disease may be particularly susceptible. 2 2 2 2 2 2 2 2 2 3 3 3

(författare) Childhood injury after a parental cancer diagnosis 2015 Ingår i: eLIFE. - Stockholm : eLife Sciences Publications Ltd. - 2050-084X. ; 4 Tidskriftsartikel (refereegranskat)abstract A parental cancer diagnosis is psychologically straining for the whole family. We investigated whether a parental cancer diagnosis is associated with a higher-than-expected risk of injury among children by using a Swedish nationwide register-based cohort study. Compared to children without parental cancer, children with parental cancer had a higher rate of hospital contact for injury during the first year after parental cancer diagnosis (hazard ratio [HR]=1.27, 95% confidence interval [CI]=1.22-1.33), especially when the parent had a comorbid psychiatric disorder after cancer diagnosis (HR=1.41, 95% CI=1.08-1.85). The rate increment declined during the second and third year after parental cancer diagnosis (HR=1.10, 95% CI=1.07-1.14) and became null afterwards (HR=1.01, 95% CI=0.99-1.03). Children with parental cancer also had a higher rate of repeated injuries than the other children (HR=1.13, 95% CI= 1.12-1.15). Given the high rate of injury among children in the general population, our findings may have important public health implications.

This study aimed to investigate the associations of parental cancer with IQ, stress resilience, and physical fitness of the affected men during early adulthood.Materials and methods: In this Swedish population-based study, we included 465,249 men born during 1973-1983 who underwent the military conscription examination around the age of 18 years. We identified cancer diagnoses among the parents of these men from the Cancer Register. IQ, stress resilience, and physical fitness of the men were assessed at the time of conscription and categorized into three levels: low, moderate, and high (reference category). We used multinomial logistic regression to assess the studied associations. Results: Overall, parental cancer was associated with higher risks of low stress resilience (relative risk ratio [RRR]: 1.09 [95% confidence interval (CI) 1.04-1.15]) and low physical fitness (RRR: 1.12 [95% CI 1.05-1.19]). Stronger associations were observed for parental cancer with a poor expected prognosis (low stress resilience: RRR: 1.59 [95% CI 1.31-1.94]; low physical fitness: RRR: 1.45 [95% CI 1.14-1.85]) and for parental death after cancer diagnosis (low stress resilience: RRR: 1.29 [95% CI 1.16-1.43]; low physical fitness: RRR: 1.40 [95% CI 1.23-1.59]). Although there was no overall association between parental cancer and IQ, parental death after cancer diagnosis was associated with a higher risk of low IQ (RRR: 1.11 [95% CI 1.01-1.24]).Conclusion: Parental cancer, particularly severe and fatal type, is associated with higher risks of low stress resilience and low physical fitness among men during early adulthood. Men who experienced parental death after cancer diagnosis also have a higher risk of low IQ.

(författare) Marital status, telomere length and cardiovascular disease risk in a Swedish prospective cohort 2020 Ingår i: Heart. - : BMJ Publishing Group Ltd. - 1355-6037 .- 1468-201X. ; 106:4, s. 267-272 Tidskriftsartikel (refereegranskat)abstract OBJECTIVE: To investigate if marital status is associated with risk of cardiovascular disease (CVD) and to explore the potential influence of leucocyte telomere length (LTL), a marker of biological ageing, on such association.DESIGN: Population-based prospective cohort study SETTINGS: Swedish Twin Registry.PARTICIPANTS: Based on the Screening Across the Lifespan Twin Study from the Swedish Twin Registry, we included 10 058 twins born between 1900 and 1958 who underwent an interview between 1998 and 2002 during which information about marital status was collected. Blood samples from these participants were subsequently collected between 2004 and 2008 and used for LTL assessment using quantitative PCR technique.MAIN OUTCOME MEASURES: Incident cases of CVD were identified through the Swedish Patient Register and Causes of Death Register through December 31, 2016. Multivariable linear regression and Cox proportional hazards regression models were used to estimate the regression coefficients (βs) and HRs with 95% CIs respectively. Potential confounders included age, sex, educational attainment and body mass index.RESULTS: A total of 2010 participants were diagnosed with CVD during a median follow-up of 9.8 years. LTL was shorter among individuals living singly, including those who were divorced or separated (β:-0.014, 95% CI: -0.035, 0.007), widowed (β:-0.035, 95% CI: -0.061, -0.010), or living alone (β:-0.033, 95% CI: -0.052, -0.014), than individuals who were married or cohabitating. One SD increase of LTL was associated with a lower risk of CVD (HR: 0.79, 95% CI: 0.66, 0.93). Individuals who were divorced or separated, widowed, or living alone had a higher risk of CVD than individuals who were married or cohabitating. The summary HR of CVD was 1.21 (95% CI: 1.08, 1.35) when comparing individuals who were living singly, regardless of reason, with the individuals who were married or cohabitating. LTL appeared to mediate little of the association between marital status and CVD (HR additionally adjusted for LTL: 1.20; 95% CI: 1.08, 1.34).CONCLUSIONS: Living singly, regardless of reason, was associated with a shorter LTL and a higher risk of CVD. The association between marital status and CVD was however not greatly attributable to telomere shortening.

This study aimed to assess the impact of parental cancer on the risk of childhood death.Methods: A population-based cohort study was conducted using the Swedish national registries, including 2,871,242 children followed during the period of 1991-2009. Parental cancer diagnosis was defined as a time-varying exposure. We used Cox proportional hazards regression to calculate the hazard ratio (HR) and its corresponding 95% confidence interval (CI) as an estimate of the association between parental cancer and childhood mortality. We adjusted for attained age, sex, gestational age, mode of delivery and birth weight of the child, maternal age at child's birth, as well as educational level and socioeconomic classification of the parents in the analyses.Results: Among 113,555 children with parental cancer, 127 deaths occurred during 561,198 person-years of follow-up. A parental cancer diagnosis was associated with an increased rate of death among children at the age of 1-18 (HR for all-cause death: 1.39; 95% CI: 1.16-1.66). For young children (aged 112), an increased rate was only noted for death due to cancer (HR: 2.06; 95% CI: 1.13-3.75) after parental cancer diagnosis. Among adolescents (aged 13-18), an increased rate was noted for all-cause death (HR: 1.52; 95% CI: 1.25-1.86), and for both non-cancer-related (HR: 1.43; 95% CI: 1.14-1.79) and cancer-related (HR: 2.07; 95% CI: 1.33-3.24) death in the exposed children.Conclusion: Children have an increased rate of death if they have a parent diagnosed with cancer as compared to children without such experience; this association appears to be slightly stronger among adolescents.

For each exposed child, we randomly selected 10 unexposed children from the general population after individual matching by year of birth and sex. The matched cohort was followed during 2001-2010. Clinical diagnoses of psychiatric disorders and use of prescribed psychiatric medications were identified for all children. Cox regression and logistic regression were used to evaluate the associations of parental cancer with psychiatric disorder diagnosis and psychiatric medication use respectively.RESULTS: Parental cancer during pregnancy was not associated with the risk of psychiatric disorders overall, although paternal cancer during pregnancy was associated with a higher risk of psychiatric medication use among females. Parental cancer after birth was associated with higher risks of psychiatric disorder diagnoses, particularly stress reaction and adjustment disorders (males:hazard ratio[HR]:1.24, 95% confidence interval[CI]:1.08-1.43; females:HR:1.27, 95%CI:1.14-1.41), and use of psychiatric medication (males:odds ratio[OR]:1.09, 95%CI:1.04-1.13;females:OR:1.14, 95%CI:1.10-1.18). The positive associations were stronger for parental cancer with poor expected survival and for parental death after cancer diagnosis.CONCLUSIONS: Parental cancer, primarily the life-threatening cancer, might confer a higher risk of psychiatric disorders among children. These findings have potential implications for healthcare professionals in providing targeted support to children living with a parent with cancer.

Cohorts were created from the Swedish Total Population Register linked to health and population registers. Data were analyzed from March 2022 to April 2023.EXPOSURES: Potentially traumatic events, including various types of assault, injuries, and bereavement (death of a child or of a spouse or partner), were ascertained from the Swedish national registers.MAIN OUTCOMES AND MEASURES: Incident psychiatric disorders were ascertained from the Swedish Patient Register. Flexible parametric and Cox models were used to estimate associations of potentially traumatic events with incident psychiatric disorders after multivariable adjustment.RESULTS: The median (IQR) age at exposure to assault, injury, and bereavement was 22 (18-31), 19 (8-40), and 60 (51-68) years, respectively. During a median (IQR) follow-up of 4.9 (2.2-8.2), 9.1 (4.1-15.6), and 8.1 (3.4-14.8) years, the incidence rates of any psychiatric disorder were 38.1, 13.9, and 9.0 per 1000 person-years for the exposed groups of the 3 cohorts, respectively. Elevated risk of any psychiatric disorder was observed during the first year after exposure to any assault (hazard ratio [HR], 4.55; 95% CI, 4.34-4.77), injury (HR, 3.31; 95% CI,3.23-3.38), or bereavement (HR, 2.81; 95% CI, 2.72-2.91) and thereafter (assault HR, 2.50; 95% CI, 2.43-2.56; injury HR, 1.69; 95% CI, 1.68-1.70; bereavement HR, 1.42; 95% CI, 1.40-1.44). Comparable associations were obtained in sibling comparison (first year: assault HR, 3.70; 95% CI, 3.37-4.05; injury HR, 2.98; 95% CI, 2.85-3.12; bereavement HR, 2.72; 95% CI, 2.54-2.91; thereafter: assault HR, 1.93; 95% CI, 1.84-2.02; injury HR, 1.51; 95% CI, 1.48-1.53; bereavement HR, 1.35; 95% CI, 1.31-1.38). The risk elevation varied somewhat by type of traumatic events and psychiatric disorders, with the greatest HR noted for posttraumatic stress disorder after sexual assault (sibling comparison HR, 4.52; 95% CI, 3.56-5.73 during entire follow-up period).CONCLUSIONS AND RELEVANCE: In this study, the long-term risk elevation of psychiatric disorders after potentially traumatic events was largely independent of familial factors. The risk elevation observed immediately after these events motivates early clinical surveillance and mental health services for these vulnerable populations.

(författare) Short-term improvement of mental health after a COVID-19 vaccination. 2023 Ingår i: PloS one. - : Public Library of Science (PLoS). - 1932-6203. ; 18:2 Tidskriftsartikel (refereegranskat)abstract The role of COVID-19 vaccination on the mental health of the general population remains poorly understood. This study aims to assess the short-term change in depressive and anxiety symptoms in relation to COVID-19 vaccination among Swedish adults.A prospective study of 7,925 individuals recruited from ongoing cohort studies at the Karolinska Institutet, Stockholm, Sweden, or through social media campaigns, with monthly data collections on self-reported depressive and anxiety symptoms from December 2020 to October 2021 and COVID-19 vaccination from July to October 2021. Prevalence of depressive and anxiety symptoms (defined as a self-reported total score of ≥10 in PHQ-9 and GAD-7, respectively) was calculated one month before, one month after the first dose, and, if applicable, one month after the second dose. For individuals not vaccinated or choosing not to report vaccination status (unvaccinated individuals), we selected three monthly measures of PHQ-9 and GAD-7 with 2-month intervals in-between based on data availability.5,079 (64.1%) individuals received two doses of COVID-19 vaccine, 1,977 (24.9%) received one dose, 305 (3.9%) were not vaccinated, and 564 (7.1%) chose not to report vaccination status. There was a lower prevalence of depressive and anxiety symptoms among vaccinated, compared to unvaccinated individuals, especially after the second dose. Among individuals receiving two doses of vaccine, the prevalence of depressive and anxiety symptoms was lower after both first (aRR = 0.82, 95%CI 0.76-0.88 for depression; aRR = 0.81, 95%CI 0.73-0.89 for anxiety) and second (aRR = 0.79, 95%CI 0.73-0.85 for depression; aRR = 0.73, 95%CI 0.66-0.81 for anxiety) dose, compared to before vaccination. Similar results were observed among individuals receiving only one dose (aRR = 0.76, 95%CI 0.68-0.84 for depression; aRR = 0.82, 95%CI 0.72-0.94 for anxiety), comparing after first dose to before vaccination.We observed a short-term improvement in depressive and anxiety symptoms among adults receiving COVID-19 vaccines in the current pandemic. Our findings provide new evidence to support outreach campaigns targeting hesitant groups.

However, given that ACEs and psychiatric disorders cluster within families, it remains to be comprehensively assessed to what extent familial confounding contributes to associations between ACEs and clinically confirmed adult psychiatric disorders.OBJECTIVE: To investigate whether associations between ACEs and adult mental health outcomes remain after adjusting for familial (genetic and environmental) confounding.DESIGN, SETTING, AND PARTICIPANTS: This Swedish twin cohort study used a discordant twin pair design based on monozygotic (MZ) and dizygotic (DZ) twins. A total of 25 252 adult twins (aged 18-47 years) from the Swedish Twin Registry born between 1959 and 1998 were followed up from age 19 years until 2016, with a maximum follow-up time of 39 years. Data were analyzed from April 2022 to November 2023.EXPOSURES: A total of 7 ACEs, including family violence, emotional abuse or neglect, physical neglect, physical abuse, sexual abuse, rape, and hate crime, were assessed with items from the Life Stressor Checklist-Revised in a web-based survey.MAIN OUTCOMES AND MEASURES: Adult (ages >18 years) clinical diagnosis of psychiatric disorders (ie, depressive, anxiety, alcohol or drug misuse, or stress-related disorders) were obtained from the Swedish National Patient Register.RESULTS: Of 25 252 twins included in the study (15 038 female [59.6%]; mean [SD] age at ACE assessment, 29.9 [8.7] years), 9751 individuals (38.6%) reported exposure to at least 1 ACE. A greater number of ACEs was associated with increased odds of any psychiatric disorder in the full cohort (odds ratio [OR] per additional ACE, 1.52; 95% CI, 1.48-1.57). The association remained but ORs per additional ACE were attenuated in DZ (1.29; 95% CI, 1.14-1.47) and MZ (1.20; 95% CI, 1.02-1.40) twin pairs. Individuals who were exposed to sexual abuse compared with those who were not exposed had increased odds of any clinically confirmed psychiatric disorder in all comparisons: full cohort (OR, 3.09; 95% CI, 2.68-3.56), DZ twin pairs (OR, 2.10; 95% CI, 1.33-3.32), and MZ twin pairs (1.80; 95% CI, 1.04-3.11).CONCLUSIONS AND RELEVANCE: This study found that associations between ACEs and adult mental health outcomes remained after controlling for shared genetic and environmental factors, which was particularly evident after multiple ACEs or sexual abuse. These findings suggest that targeted interventions may be associated with reduced risks of future psychopathology.

Participants in the current study were 26,198 women with data on 13 ACEs measured with the ACE-International Questionnaire. Self-reported coping ability was measured with the Connor-Davidson Resilience Scale and psychiatric resilience was operationalized as absence of psychiatric morbidity. Generalized linear regression assuming normal or Poisson distribution were used to assess the associations of ACEs with coping ability and psychiatric resilience controlling for multiple confounders.Results: Number of ACEs was inversely associated with adult resilience in a dose-dependent manner; every 1SD unit increase in ACE scores was associated with both lower levels of coping ability (β = -0.14; 95% CI-0.15,-0.13) and lower psychiatric resilience (β = -0.28; 95% CI-0.29,-0.27) in adulthood. Compared to women with 0 ACEs, women with ≥5 ACEs had 36% lower prevalence of high coping ability (PR = 0.64, 95% CI 0.59,0.70) and 58% lower prevalence of high psychiatric resilience (PR = 0.42; 95% CI 0.39,0.45). Specific ACEs including emotional neglect, bullying, sexual abuse and mental illness of household member were consistently associated with reduced adult resilience. We observed only slightly attenuated associations after controlling for adult socioeconomic factors and social support in adulthood.Conclusions: Cumulative ACE exposure is associated with lower adult resilience among women, independent of adult socioeconomic factors and social support, indicating that adult resilience may be largely determined in childhood.

We prospectively investigated the influence of metabolic syndrome and its components on risk of total prostate cancer and measures of aggressive disease in a cohort of Icelandic men. Men in the Reykjavik Study (n = 9,097, enrolled 1967-1987) were followed for incident (n = 1,084 total; n = 378 advanced; n = 148 high-grade) and fatal (n = 340) prostate cancer until 2014. Cox regression was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for (1) measured metabolic factors at cohort entry (body mass index (BMI), blood pressure, triglycerides, fasting blood glucose) and (2) a metabolic syndrome score (range 0-4) combining the risk factors: BMI ≥30 kg/m2 ; systolic blood pressure (SBP) ≥130 or diastolic blood pressure (DBP) ≥85 mm Hg or taking antihypertensives; triglycerides ≥150 mg/dl; fasting blood glucose ≥100 mg/dl or self-reported type 2 diabetes. Hypertension and type 2 diabetes were associated with a higher risk of total, advanced, high-grade, and fatal prostate cancer, independent of BMI. Neither BMI nor triglycerides were associated with prostate cancer risk. Higher metabolic syndrome score (3-4 vs 0) was associated with a higher risk of fatal prostate cancer (HR 1.55; 95% CI: 0.89, 2.69; p trend = 0.08), although this finding was not statistically significant. Our findings suggest a positive association between midlife hypertension and diabetes and risk of total and aggressive prostate cancer. Further, metabolic syndrome as a combination of factors was associated with an increased risk of fatal prostate cancer.
39.	Fall, Katja, 1971-, et al. (författare) Immediate risk for cardiovascular events and suicide following a prostate cancer diagnosis : prospective cohort study 2009 Ingår i: PLoS Medicine. - San Francisco, Calif. : Public Library of Science. - 1549-1277 .- 1549-1676. ; 6:12, s. e1000197- Tidskriftsartikel (refereegranskat)abstract BACKGROUND: Stressful life events have been shown to be associated with altered risk of various health consequences. The aim of the present study was to investigate whether the emotional stress evoked by a prostate cancer diagnosis increases the immediate risks of cardiovascular events and suicide.METHODS AND FINDINGS: We conducted a prospective cohort study by following all men in Sweden who were 30 y or older (n = 4,305,358) for a diagnosis of prostate cancer (n = 168,584) and their subsequent occurrence of cardiovascular events and suicide between January 1, 1961 and December 31, 2004. We used Poisson regression models to calculate relative risks (RRs) and 95% confidence intervals (CIs) of cardiovascular events and suicide among men who had prostate cancer diagnosed within 1 y to men without any cancer diagnosis. The risks of cardiovascular events and suicide were elevated during the first year after prostate cancer diagnosis, particularly during the first week. Before 1987, the RR of fatal cardiovascular events was 11.2 (95% CI 10.4-12.1) during the first week and 1.9 (95% CI 1.9-2.0) during the first year after diagnosis. From 1987, the RR for cardiovascular events, nonfatal and fatal combined, was 2.8 (95% CI 2.5-3.2) during the first week and 1.3 (95% CI 1.3-1.3) during the first year after diagnosis. While the RR of cardiovascular events declined, the RR of suicide was stable over the entire study period: 8.4 (95% CI 1.9-22.7) during the first week and 2.6 (95% CI 2.1-3.0) during the first year after diagnosis. Men 54 y or younger at cancer diagnosis demonstrated the highest RRs of both cardiovascular events and suicide. A limitation of the present study is the lack of tumor stage data, which precluded possibilities of investigating the potential impact of the disease severity on the relationship between a recent diagnosis of prostate cancer and the risks of cardiovascular events and suicide. In addition, we cannot exclude residual confounding as a possible explanation.CONCLUSIONS: Men newly diagnosed with prostate cancer are at increased risks for cardiovascular events and suicide. Future studies with detailed disease characteristic data are warranted.

A linear regression model was used to assess the potential trend of the incidence during calendar years. We also followed up the entire population registered in the 1990 Population and Housing Census for incidence of ALS. Relative risk and 95% confidence interval of ALS associated with demographic variables were estimated using Poisson regression models.Results: The age-standardized incidence rates increased from 2.32 per 100,000 person-years in 1991-1993 to 2.98 per 100,000 person-years in 2003-2005, representing an annual increase of approximately 2% during the 15 years (P value for trend, .002). The age-specific incidence rates increased in all age groups except those younger than 50 years. The observed increase remained significant when restricting the analysis to individuals born in Sweden (P value for trend, <.001). Compared with individuals born from April through June, those born from October through December were at 11% increased risk of ALS (95% confidence interval, 1.01-1.23).Conclusions: The incidence of ALS has been increasing during the last 15 years in Sweden. Further studies are warranted to explore the underlying reasons for this observed trend.

Methods: We studied the association between hospitalization for osteoarthritis prior to PCa diagnosis, as a surrogate for heavy use of NSAIDs, and PCa specific mortality in a large population of PCa patients in Sweden in 1980-2004. Results: Hospitalization for osteoarthritis before PCa diagnosis was associated to a lower PCa specific mortality (hazard ratio [HR], 0.92; 95% confidence interval [CI], 0.88-0.96), but not to the risk of death from other causes (HR, 1.03; 95% Cl, 0.99-1.08). The association was stronger among younger patients and patients diagnosed in earlier calendar years. Conclusions: Our data demonstrate a modestly decreased PCa specific mortality among PCa patients with hospitalization for osteoarthritis prior to PCa diagnosis, compared to those without such experience. This finding lends support to the hypothesis that NSAIDs use may influence PCa progression.

Follow-up started from the date of prostate cancer diagnosis to the end of first 12 calendar months after diagnosis. The relative risks of suicide and cardiovascular death were calculated as standardized mortality ratios (SMRs) comparing corresponding incidences among prostate cancer patients with those of the general US male population, with adjustment for age, calendar period, and state of residence. We compared risks in the first year and months after a prostate cancer diagnosis. The analyses were further stratified by calendar period at diagnosis, tumor characteristics, and other variables.Results: During follow-up, 148 men died of suicide (mortality rate = 0.5 per 1000 person-years) and 6845 died of cardiovascular diseases (mortality rate = 21.8 per 1000 person-years). Patients with prostate cancer were at increased risk of suicide during the first year (SMR = 1.4, 95% confidence interval [CI] = 1.2 to 1.6), especially during the first 3 months (SMR = 1.9, 95% CI = 1.4 to 2.6), after diagnosis. The elevated risk was apparent in pre-prostate-specific antigen (PSA) (1979-1986) and peri-PSA (1987-1992) eras but not since PSA testing has been widespread (1993-2004). The risk of cardiovascular death was slightly elevated during the first year (SMR = 1.09, 95% CI = 1.06 to 1.12), with the highest risk in the first month (SMR = 2.05, 95% CI = 1.89 to 2.22), after diagnosis. The first-month risk was statistically significantly elevated during the entire study period, and the risk was higher for patients with metastatic tumors (SMR = 3.22, 95% CI = 2.68 to 3.84) than for those with local or regional tumors (SMR = 1.57, 95% CI = 1.42 to 1.74).Conclusion: A diagnosis of prostate cancer may increase the immediate risks of suicide and cardiovascular death.

The study comprised 2,694 incident ALS cases and five controls per case individually matched by year of birth, gender, and parity. Odds ratios and their corresponding 95% confidence intervals for ALS were estimated by using conditional logistic regression models. Compared with that for parents who never lost a child, the overall odds ratio of ALS for bereaved parents was 0.7 (95% confidence interval (CI): 0.6, 0.8) and decreased to 0.4 (95% CI: 0.2, 0.8) 11-15 years after the loss. The risk reduction was also modified by parental age at the time of loss, with the lowest odds ratio of 0.4 (95% CI: 0.2, 0.9) for parents older than age 75 years. Loss of a child due to malignancy appeared to confer a lower risk of ALS (odds ratio = 0.5, 95% CI: 0.3, 0.8) than loss due to other causes. These data indicate that the risk of developing ALS decreases following the severe stress of parental bereavement. Further studies are needed to explore potential underlying mechanisms.

We conducted a population-based cohort study in Sweden between 1965 and 2004, which comprised of 6642 patients with incident ALS identified from the Swedish Inpatient Register. We calculated the standardized mortality ratios (SMRs) of suicide among the patients using the suicide rates of the general Swedish population as a reference. In total, 21 patients committed suicide during follow-up, compared to the predicted 3.6 suicides. Thus, we noted an almost 6-fold increased risk for suicide among ALS patients [SMR 5.8, 95% confidence interval (CI) 3.6-8.8]. Patients who committed suicide were, on average, around 7 years younger at the time of their first period of hospitalization than patients who did not commit suicide. The highest relative risk for suicide was observed within the first year after the patients first period of hospitalization (SMR 11.2, 95% CI 5.8-19.6). After that, the relative risks decreased with time after hospitalization (P-value for trend = 0.006), but remained elevated 3 years later. The relative risks of suicide among ALS patients did not show a clear trend over time in contrast to the decreasing trend of relative risks for suicide among patients with cancer during the same period. Patients with ALS are at excess risk of suicide in Sweden and the relative risk is higher during the earlier stage of the disease.

To adjust for unmeasured confounders, we also performed a nested, self-matched case-crossover analysis among all patients with cancer who died from suicide or cardiovascular diseases in the cohort.Results: As compared with cancer-free persons, the relative risk of suicide among patients receiving a cancer diagnosis was 12.6 (95% confidence interval [CI], 8.6 to 17.8) during the first week (29 patients; incidence rate, 2.50 per 1000 person-years) and 3.1 (95% CI, 2.7 to 3.5) during the first year (260 patients; incidence rate, 0.60 per 1000 person-years). The relative risk of cardiovascular death after diagnosis was 5.6 (95% CI, 5.2 to 5.9) during the first week (1318 patients; incidence rate, 116.80 per 1000 person-years) and 3.3 (95% CI, 3.1 to 3.4) during the first 4 weeks (2641 patients; incidence rate, 65.81 per 1000 person-years). The risk elevations decreased rapidly during the first year after diagnosis. Increased risk was particularly prominent for cancers with a poor prognosis. The case-crossover analysis largely confirmed results from the main analysis.Conclusions: In this large cohort study, patients who had recently received a cancer diagnosis had increased risks of both suicide and death from cardiovascular causes, as compared with cancer-free persons.

In a population-based study, 691 (76%) of 907 Swedish men who lost a wife to breast, ovarian, or colon cancer in 2000 or 2001 answered an anonymous questionnaire in 2004 or 2005 measuring preparedness at the time of the wife's death and psychological well-being at follow-up. Men aged 38-61 years with a low degree of preparedness at the time of their spouse's death had increased risk of psychological morbidity and other symptoms, such as anxiety (adjusted relative risk (aRR) = 2.1, 95% confidence interval (CI): 1.0, 4.3), a heightened startle response (aRR = 5.3, 95% CI: 1.2, 23.6), emotional numbness (aRR = 2.1, 95% CI: 1.2, 3.6), little or no grief resolution (aRR = 2.7, 95% CI: 1.3, 5.4), and sleep disorders (aRR = 2.3, 95% CI: 1.2, 4.3), 4-5 years after the loss. For older widowers (aged 62-80 years), a low degree of preparedness increased the risk of having repeated painful memories (aRR = 2.8, 95% CI: 1.5, 5.2) and a heightened startle response (aRR = 5.7, 95% CI: 1.5, 21.4) at follow-up. These results show that to improve the long-term psychological well-being of widowers, it may be fruitful to identify care-related facilitators and inhibitors of preparedness.

A further aim of the study was to investigate if being in a new relationship at the time of follow-up affects the risk of psychological morbidity. METHOD: In a population-based cohort study, we collected data from 907 men in Sweden who lost a wife to cancer in the breast, ovary or colon 4-5years earlier. A control group of 330 married men was also included. RESULTS: Six hundred ninety-one of the widowers (76%) and 262 of the controls (79%) answered a questionnaire. Widowers in a new relationship had a similar risk of psychological morbidity compared with a control group of married men. However, compared with widowers in a new relationship, single widowers reported increased risks of (among other symptoms) the following: depression (RR 2.2, confidence interval [CI] 1.5-3.2), anxiety (RR 1.6, CI 1.1-2.5) emotional numbness (RR 2.2, CI 1.7-2.8), and waking up at night with anxiety (RR 2.2, CI 1.4-3.7). CONCLUSIONS: Men who lost a wife to cancer in Sweden in 2000 or 2001 and are single 4-5years later have increased risks of psychological morbidity, both compared with widowers who are in a new relationship at the time of follow-up and with married men. Further scientific effort is needed for improved understanding of the most likely underlying mechanisms; that is, that enhanced emotional support of a new relationship after the loss of a wife protects against psychological morbidity, or alternatively, that the healthiest widowers enter a new relationship.

(författare) Aspirin and other non-steroidal anti-inflammatory drugs and depression, anxiety, and stress-related disorders following a cancer diagnosis : a nationwide register-based cohort study 2020 Ingår i: BMC Medicine. - : BioMed Central. - 1741-7015. ; 18:1 Tidskriftsartikel (refereegranskat)abstract BACKGROUND: Cancer patients have a highly increased risk of psychiatric disorders following diagnosis, compared with cancer-free individuals. Inflammation is involved in the development of both cancer and psychiatric disorders. The role of non-steroidal anti-inflammatory drugs (NSAIDs) in the subsequent risk of psychiatric disorders after cancer diagnosis is however unknown.METHODS: We performed a cohort study of all patients diagnosed with a first primary malignancy between July 2006 and December 2013 in Sweden. Cox proportional hazards models were used to assess the association of NSAID use during the year before cancer diagnosis with the risk of depression, anxiety, and stress-related disorders during the first year after cancer diagnosis.RESULTS: Among 316,904 patients identified, 5613 patients received a diagnosis of depression, anxiety, or stress-related disorders during the year after cancer diagnosis. Compared with no use of NSAIDs, the use of aspirin alone was associated with a lower rate of depression, anxiety, and stress-related disorders (hazard ratio [HR], 0.88; 95% confidence interval [CI], 0.81 to 0.97), whereas the use of non-aspirin NSAIDs alone was associated with a higher rate (HR, 1.24; 95% CI, 1.15 to 1.32), after adjustment for sociodemographic factors, comorbidity, indications for NSAID use, and cancer characteristics. The association of aspirin with reduced rate of depression, anxiety, and stress-related disorders was strongest for current use (HR, 0.84; 95% CI, 0.75 to 0.93), low-dose use (HR, 0.88; 95% CI, 0.80 to 0.98), long-term use (HR, 0.84; 95% CI, 0.76 to 0.94), and among patients with cardiovascular disease (HR, 0.81; 95% CI, 0.68 to 0.95) or breast cancer (HR, 0.74; 95% CI, 0.56 to 0.98).CONCLUSION: Pre-diagnostic use of aspirin was associated with a decreased risk of depression, anxiety, and stress-related disorders during the first year following cancer diagnosis.
