This thesis focuses on charge transport in semiconductor InSb nanowire quantum devices, including the electron transport, the hole transport, and the Cooper pair transport. Devices in which InSb semiconductor nanowire quantum dots are coupled with normal metals, superconductors or the proximity effect induced topological superconductors are fabricated and measured. Firstly, we have fabricated and

Purpose: To examine risks of attention-deficit/hyperactivity disorder (ADHD) in preterm and early term birth survivors, and potential sex-specific differences. Methods: A national cohort study was conducted of all 4061,795 singletons born in Sweden in 1973–2013 who survived infancy, followed up for ADHD identified from nationwide diagnoses and medications through 2018. Poisson regression was used

Barriers to healthcare for men who have sex with men (MSM) in sub-Saharan Africa (SSA) are rooted in stigma and discrimination against MSM fuelled by the criminalization of homosexuality. These barriers are influenced by factors involving MSM and the healthcare workers (HCWs). MSM are uncomfortable disclosing their identities and conceal symptoms of sexually transmitted infections (STIs), especial

Background Relying on freezer stored biospecimens is preferred in epidemiolocal studies exploring environmental pregnancy exposures and later offspring health. Storage duration may increase the pre-analytical variability, potentially adding measurement uncertainty. We investigated evaporation of maternal serum after long-term biobank storage using ions (sodium, Na+; chloride, Cl-) recognized for s

Objective: The purpose of this study was to determine whether alcohol use disorder (AUD) can be transmitted contagiously in siblings and likely acquaintances growing up close to one another (Propinquity-of-Rearing Defined Acquaintances [PRDAs]). Method: PRDAs were pairs of same-age subjects growing up within 1 km of each other and sharing the same school class, where one of whom (PRDA1) was first

Artikeln beskriver hur en grammatikdidaktisk modell utformad för en L1-kontext kan användas för grammatikundervisning såväl som för ett språk- och skrivutvecklande arbete i en L2-kontext. Eftersom klassrummen i Sverige, Danmark och Norge allt mer blir språkligt heterogena behöver lärare kunna erbjuda en språkutvecklande under-visning för elever med skilda språkliga förutsätThe article shows how a grammar-didactic model designed for an L1 context can be used for grammar learning as well as language and writing development in an L2 con-text. Because classrooms in Sweden, Denmark and Norway are becoming increasingly heterogenous, teachers must be able to develop the language of pupils with differing linguistic predispositions. The model that

Active vitamin D is commonly used to control secondary hyperparathyroidism in dialysis patients, but it is unknown whether active vitamin D directly improves bone strength, independently of its ability to suppress parathyroid hormone (PTH). We analyzed the association between the prescription of active vitamin D and incidence of any fracture and hip fracture in 41,677 in-center hemodialysis patien

We aimed (i) to gain a better understanding of the demographic and socioeconomical distribution of ADHD risk in Sweden; and (ii) to contribute to the critical discussion on medicalization, i.e., the tendency to define and treat behavioural and social problems as medical entities. For this purpose, we analysed the risk of suffering from ADHD in the whole Swedish population aged between 5 and 60 yea

BACKGROUND: The significant role of long non-coding 7S RNA in controlling mitochondrial transcription highlights its importance in mitochondrial function. Considering the suggested connection between mitochondrial dysfunction and the onset of mental disorders, this study aimed to explore the potential involvement of 7S RNA in the context of depression/anxiety.RESULTS: A total of 181 patients in pr

Using Swedish registers, we examine whether the prescription of and the response to antidepressants (AD), mood stabilizers (MS), and antipsychotics (AP) in the treatment of, respectively, major depression (MD), bipolar disorder (BD), and schizophrenia (SZ), are influenced by familial-genetic risk. We examined individuals born in Sweden 1960–1995 with a first diagnosis of MD (n = 257,177), BD (n =

Background Prior research has reported an association between divorce and suicide attempt. We aimed to clarify this complex relationship, considering sex differences, temporal factors, and underlying etiologic pathways. Methods We used Swedish longitudinal national registry data for a cohort born 1960-1990 that was registered as married between 1978 and 2018 (N = 1 601 075). We used Cox proportion

Background: There are two primary phenotypic models of comorbidity between post-traumatic stress disorder (PTSD) and drug use disorder (DUD), i.e. self-medication (PTSD precedes and causes DUD) and susceptibility (DUD precedes and causes PTSD). We sought to clarify the longitudinal relationship between PTSD and DUD, while examining sex differences. Method: We used approximately 23 years of longitu

Background Preterm birth is associated with pulmonary complications early in life; however, long-term risks of asthma into adulthood are unclear. Objective To determine asthma risks from childhood into adulthood associated with gestational age at birth in a large population-based cohort. Methods A national cohort study was conducted of all 4 079 878 singletons born in Sweden during 1973-2013, foll

Background: Pain is associated with falls, disability and a poor quality of life among older adults. It is highly prevalent in many societies, and studies have shown that pain could be preventable or managed more effectively at the population level. However, few studies have investigated who is at higher risk of pain in the general population, which is important for development of effective interv

Cardiovascular disease (CVD) development may be linked to persistent organic pollutants (POPs), including organochlorine compounds (OCs) and perfluoroalkyl and polyfluoroalkyl substances (PFAS). To explore underlying mechanisms, we investigated metabolites, proteins, and genes linking POPs with CVD risk. We used data from a nested case-control study on myocardial infarction (MI) and stroke from th

BACKGROUND: Suicidal behavior and substance use disorders (SUDs) are important public health concerns. Prior suicide attempts and SUDs are two of the most consistent predictors of suicide death, and clarifying the role of SUDs in the transition from suicide attempt to suicide death could inform prevention efforts. METHODS: We used national Swedish registry data to identify individuals born 1960-19

Background One potential cause of comorbidity is the direct causal effect of one disorder - A - on risk for subsequent onset of disorder B. Could genetic risk scores be utilized to test for such an effect? If disorder A causally impacts on risk for disorder B, then genetic risk for disorder A should be lower in cases of disorder A with v. without a prior onset of B. Methods In all individuals (n =

We used Swedish national-register data (N = 2,828,777) to examine divorce and its associated patterns of family genetic-risk scores (FGRSs; personalized measures of genetic risk inferred from diagnoses in relatives) across 10 psychiatric disorders: major depression, anxiety disorders, obsessive compulsive disorder, bipolar disorder, schizophrenia, anorexia nervosa, alcohol use disorder, drug use d
