Background: Our aim was to study the association between the country of birth and incident end-stage kidney disease (ESKD) in several immigrant groups in Sweden, using individuals born in Sweden or with Swedish-born parents as referents. Methods: A cohort study of first- and second-generation immigrants residing in Sweden between January 1, 1998 and December 31, 2012 was performed. Outcomes were d
With complete genealogical and cohabitation information, new genetic-epidemiological designs can be developed to clarify causes of parent-offspring transmission. We propose the Multiple Parenting Relationships (MPR) Design and apply it to drug abuse (DA) and alcohol use disorder (AUD). Using national Swedish registries, we identified four kinds of informative parents with multiple children with wh
Background: Abdominal obesity is on the increase worldwide and ethnic minority groups are at high risk. However, studies of the underlying causes are scarce. The aims of this study were to investigate the prevalence of abdominal obesity and to identify metabolic, lifestyle and socio-demographic risk factors associated with abdominal obesity in male and female residents of Malmö, a city in southern
Risk of dementia is increased in patients with atrial fibrillation (AF). We aimed to study associations between relevant comorbidities and prevalent as well as incident dementia in AF patients. Study population included all adults (n = 12,283) ≥ 45 years diagnosed with AF at 75 primary care centers in Sweden 2001–2007. Logistic regression was used to calculate odds ratios (OR) with 95% confidence
Previous high-risk family designs in psychiatry have focused largely on offspring of affected parents. We take a pedigree-based approach and examine the social, psychological, and psychiatric features of offspring from extended pedigrees selected for high-densities of alcohol use disorder (AUD) or drug abuse (DA). We identified, from the Swedish population, 665,715 pedigrees containing a mean of 1
Background: Spirometry, the main tool for diagnosis and follow-up of COPD, incompletely describes the disease. Based on volumetric capnography (VCap), an index was developed for the diagnosis and grading of COPD, aimed as a complement or alternative to spirometry. Methods: Nine non-smokers, 10 smokers/former smokers without COPD and 54 smokers/ former smokers with COPD were included in the study.
Background: Glaucoma has a familial component but detailed data on the modification of familial risks are lacking. The aim of the study was to determine detailed familial risks for medically diagnosed glaucoma based on nationwide hospital and population records. Methods: Subjects were obtained from the Multigeneration Register, contains the Swedish population in families, and glaucoma patients wer
Background: According to the literature the three stone diseases, sialolithiasis (SL), urolithiasis (UL) and cholelithiasis (CL) share comorbidities. We assess familial and spouse risks between these stone disease and compare them to familial risks for concordant (same) stone disease. Methods: Study population including familiar relationships was obtained from the Swedish Multigeneration Register
Background: With continuous increases in survival rates following breast cancer (BC) diagnosis, the challenge of multiple primary cancers has become an issue. The data on familial risk of SPCs after BC diagnosis and the related mortality in BC patients are scarce. Methods: A total of 87 752 female BC patients were followed for SPC diagnoses and records of death. Relative risks (RRs) of SPC in BC p
Background Raised blood pressure is an important risk factor for cardiovascular diseases and chronic kidney disease. We estimated worldwide trends in mean systolic and mean diastolic blood pressure, and the prevalence of, and number of people with, raised blood pressure, defined as systolic blood pressure of 140 mm Hg or higher or diastolic blood pressure of 90 mm Hg or higher. Methods For this an
Improvement of survival in lymphocytic leukaemia has been accompanied by the occurrence of second primary cancer (SPCs). Based on Swedish Family Cancer Database, we applied bi-directional analyses in which relative risks (RRs) were calculated for any SPCs in patients with chronic lymphocytic leukaemia (CLL), acute lymphoblastic leukaemia (ALL) and hairy cell leukaemia (HCL) and the risks of these
Inhibition of amyloid β peptide (Aβ) aggregation is an important goal due to the connection of this process with Alzheimer's disease. Traditionally, inhibitors were developed with an aim to retard the overall macroscopic aggregation. However, recent advances imply that approaches based on mechanistic insights may be more powerful. In such approaches, the microscopic steps underlying the aggregatio
Aim: To study association between country of birth and risk of first-onset atrial fibrillation (AF) in first- and second-generation immigrants to Sweden under 45 y of age.Methods: The study population included all individuals (n = 3 248 457) under the age of 45 y in Sweden, including immigrants (n = 722 249). AF was defined as first registered diagnosis in the National Patient Register. Associatio
Characteristics of the built environment, including access to unhealthy food outlets, are hypothesized to contribute to type 2 diabetes mellitus (T2D). Swedish nationwide registry data on 4,718,583 adults aged 35-80 years living in 9,353 neighborhoods, each with at least 1 food outlet, were geocoded and linked to commercial registers (e.g., restaurants and grocery stores). Multilevel logistic regr
AIMS: Some 15% of the Swedish population is born outside Sweden, originating from all continents of the world. Thalassemia and sickle cell anemia constitute the most common inherited recessive disorders globally and they are endemic in areas of Africa and Asia, origins of many immigrants to Sweden. We aimed at investigating the origins of the Swedish sickle cell and thalassemia patients.METHODS: P
Introduction: The hospitalization rate of paroxysmal supraventricular tachycardia (PSVT) in a nationwide study is not established. We determined age- and sex-specific hospitalization rates and time trends for hospitalized PSVT in the Swedish population between 1987 and 2010. Methods: This nationwide study is based on the Swedish Hospital Discharge Register. The patients with first PSVT diagnoses b
Background: Breakthroughs in the treatment of preterm birth approximately 40 years ago have enabled a generation of preterm survivors to now reach mid-adulthood. Understanding their health sequelae is essential for guiding their long-term care. We did a study to examine preterm birth in relation to mortality into mid-adulthood. Methods: A national cohort study was done of all 4 296 814 singleton l
AD730® is a new type of nickel-based superalloy, developed by Aubert & Duval, with high temperature properties exceeding conventional superalloys such as Alloy 718. This paper presents the tool life model for this superalloy for the purpose of process optimization and manufacturing cost estimation. The tool life modelling is based on comprehensive machining tests, using the Colding model. The
Chronic handicap in early life may have a long-term impact on children's psychosocial well-being. Here, we investigated whether Brachialis Plexus Birth Injury (BPBI)-an unpredictable injury at birth-is associated with worse mental health later on, as indicated by prescription and use of psychotropic drugs in adolescence. We explored further whether this association is different depending on socioe
