Familial risks of psychotic disorders and schizophrenia have been assessed in previous studies. However, the degree of familial clustering in large population datasets remains to be established. We conducted a study on familial risks of psychotic disorders and schizophrenia by linking the Multigeneration Register to the nationwide Swedish Hospital Discharge Register. All patients younger than 72 y
Population-level familial risks are not available for amyotrophic lateral sclerosis (ALS), and a few studies have analyzed familial association of ALS with other diseases. We used the Swedish Multigeneration Register to identify family members and link them to the Hospital Discharge Register to calculate standardized incidence ratios (SIRs) for familial association in ALS and 33 autoimmune disease
BACKGROUND: The aim of this study was to investigate possible associations between educational level, occupation, and hospitalization for inflammatory bowel disease.METHODS: A nationwide database was constructed by linking the Swedish Census to the Hospital Discharge Register in order to obtain data on all first hospitalizations for Crohn's disease (CD) and ulcerative colitis (UC) in Sweden during
In the era of complex disease genetics, the consideration of familial risks is important in the assessment of the likely success of these studies. In the present article, we study familial risks for multiple sclerosis (MS) among parents and offspring, singleton siblings, twins, and spouses when a family member was diagnosed with MS or any of 33 other autoimmune diseases. The availability of a Mult
BACKGROUND: Patients diagnosed with Crohn disease (CD) are known to be at an increased risk of bowel cancers and lymphoma. CD is an autoimmune disease and we hypothesize that the patients are predisposed to a wider spectrum of cancers.PATIENTS AND METHODS: A CD research database was constructed by identifying hospitalized CD patients from the Hospital Discharge Register and cancer patients from th
OBJECTIVE: Familial risks of anxiety have been assessed in small case-control studies, usually based on reported, but not medically verified, anxiety in family members; thus the degree of familial clustering of these diseases remains to be established.METHODS: The Multigeneration Register, in which all men (sons) and women (daughters) born in Sweden from 1932 onward are registered together with th
OBJECTIVE: The aim of this study was to investigate possible associations between hospitalization for multiple sclerosis (MS) and region, socioeconomic status and occupation.METHODS: A nationwide database was constructed by linking Swedish Census data to the Hospital Discharge Register (1987-2001). The hospital diagnoses of MS were based on the International Classification of Diseases. Standardize
Patients diagnosed with ulcerative colitis (UC) are known to be at an increased risk of colorectal and liver cancers and leukemia. UC is an autoimmune disease, which may present a wider spectrum of cancers. We wanted to examine the risk of cancer in a large population of UC patients in order to reach high statistical power. A UC research database was constructed by identifying UC patients from the
We present a novel family of deep neural architectures, named partially exchangeable networks (PENs) that leverage probabilistic symmetries. By design, PENs are invariant to block-switch transformations, which characterize the partial exchangeability properties of conditionally Markovian processes. Moreover, we show that any block-switch invariant function has a PEN-like representation. The DeepSe
BACKGROUND: Understanding the genetic transmission of obstructive sleep apnea syndrome (OSAS) will help clinicians identify patients at risk and offer opportunities for intervention and treatment at specialist clinics.OBJECTIVE: To estimate familial risk of hospitalization for OSAS in the adult population of Sweden, and to determine if there are any differences by age and sex.DESIGN, SETTING, AND
OBJECTIVES: To quantify the sibling risk of RA, SLE and AS. To analyse the concordant and discordant associations between RA, SLE and AS.METHODS: Follow-up study of all individuals and their siblings born in or after 1932 and hospitalized for RA, SLE or AS between 1973 and 2004 (32 yrs). Data were retrieved from a comprehensive dataconstructed by using several national Swedish data registers, incl
OBJECTIVE: To investigate possible associations between socioeconomic status, occupation, and hospitalization for rheumatoid arthritis (RA).METHODS: A nationwide database was constructed by linking the Swedish Census to the Hospital Discharge Register in order to obtain data on all first hospitalizations for RA in Sweden during the study period 1964 to 2004. Standardized incidence ratios (SIR) and
OBJECTIVE: To analyze the association between rheumatoid arthritis, systemic lupus erythematosus, and ankylosing spondylitis and hospitalization for psychiatric disorders, as well as the association between hospitalization for dementia or delirium and systemic lupus erythematosus, by using a novel, large-scale approach.DESIGN: Cohort study with follow-up between 1973 and 2004.PARTICIPANTS: The ent
BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a progressive disabling condition, for which tobacco smoking, environmental pollution, inherited alpha-antitrypsin deficiency and their interactions are predisposing factors. We carried out a family study on COPD in order to address the role of heritable and environmental risk factors at a population level.METHODS: In a nationwide study o
OBJECTIVES: Patients diagnosed with RA have been at an increased risk of many cancers and at a decreased risk of some cancers. We planned to revisit the theme by using a nation-wide population of RA patients.METHODS: An RA research database was constructed by identifying hospitalized RA patients from the Hospital Discharge Register and cancer patients from the Cancer Registry. Earlier studies from
OBJECTIVES: The aim of this study was to investigate whether there is an association between socioeconomic status, occupation and hospitalization for Parkinson's disease (PD).METHODS: A nationwide database was constructed by linking the Swedish Census to the Hospital Discharge Register to obtain data on all first adult hospitalizations for PD diagnosed in Sweden during the study period from 1987 t
OBJECTIVE: Familial risks of depression have been assessed in small case-control studies, usually based on reported, but not medically verified depressions in family members; thus the degree of familial clustering for these diseases remains to be established.METHODS: We conducted a nationwide study on familial risks of depression linking the Multigeneration Register of 0-72-year-old individuals to
This study presents an empirical approach to the use of imperfect and preterite Spanish past tenses, with state and achievement verbs by Swedish students of Spanish as a foreign language in the levels A2, B1 and B2. The main objective is to establish to what extent the participants link the use of the imperfect and the preterite in relation to state and achievement verbs. The study compares the re
