A search for heavy pseudoscalar (A) and scalar (H) Higgs bosons decaying into a top quark pair (tt) has been performed with 20.3 fb-1 of proton-proton collision data collected by the ATLAS experiment at the Large Hadron Collider at a center-of-mass energy s=8 TeV. Interference effects between the signal process and standard model tt production, which are expected to distort the signal shape from a

Background: Rheumatoid arthritis (RA) is a chronic, inflammatory rheumatic disease with the potential to induce significant disability. Patients with RA are at increased risk of cardiovascular diseases (CVD). Smokers with RA tend to experience more pain and fatigue, higher disease activity, more erosive joint destruction and a lower health-related quality of life (HR-QoL) than non-smokers. It rema

Purpose: Although adjuvant polychemotherapy improves outcomes for early breast cancer, the significant variability in terms of pharmacokinetics results in differences in efficacy and both short and long-term toxicities. Retrospective studies support the use of dose tailoring according to the hematologic nadirs. Methods: The SBG 2004-1 trial was a randomized feasibility phase II study which assesse

Aim: To investigate the fees charged by Swedish dentists for root fillings, coronal restorations and further dental interventions during a follow-up period of 5–6 years. Methodology: A total of 248 299 root fillings were linked with the tooth, the patient and the provider and entered into the Swedish Social Insurance Agency register in 2009. The data register also recorded the subsidy-based (sched

Background: Difficulty in following and understanding conversation in different daily life situations is a common complaint among persons with hearing loss. To the best of our knowledge, there is currently no published validated Norwegian questionnaire available that allows for a self-assessment of unaided communication ability in a population with hearing loss. Purpose: The aims of the present st

The inclusive cross-section for the associated production of a W boson and top quark is measured using data from proton-proton collisions at s=13 TeV. The dataset corresponds to an integrated luminosity of 3.2 fb−1, and was collected in 2015 by the ATLAS detector at the Large Hadron Collider at CERN. Events are selected requiring two opposite sign isolated leptons and at least one jet; they are se

Purpose To describe a large cohort of femtosecond laser–assisted cataract surgeries in terms of baseline characteristics and the related outcomes. Setting Eighteen cataract surgery clinics in 9 European countries and Australia. Design Prospective multicenter case series. Methods Data on consecutive eyes having femtosecond laser–assisted cataract surgery in the participating clinics were entered in

A search for long-lived, massive particles predicted by many theories beyond the Standard Model is presented. The search targets final states with large missing transverse momentum and at least one high-mass displaced vertex with five or more tracks, and uses 32.8 fb-1 of s=13 TeV pp collision data collected by the ATLAS detector at the LHC. The observed yield is consistent with the expected backg

BACKGROUND: Patients with cleft lip and/or palate can undergo numerous procedures to improve appearance, speech, dentition and hearing. We developed a cleft-specific patientreported outcome instrument to facilitate rigorous international measurement and benchmarking. METHODS: Data were collected from patients aged 8-29 years with cleft lip and/or palate at 30 hospitals in 12 countries between Octo

Results of a search for new phenomena in events with at least three photons are reported. Data from proton– proton collisions at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 20.3 fb−1, were collected with the ATLAS detector at the LHC. The observed data are well described by the Standard Model. Limits at the 95 % confidence level on new phenomena are presented bas

AIMS: To explore the perceptions of informal caregivers and healthcare professionals regarding potential reasons for the institutionalization of older persons with dementia in eight European countries. BACKGROUND: Healthcare professionals may have an important role in facilitating informal caregivers' decision-making regarding institutionalization. Little is known about the perceptions of informal

A search for heavy leptons decaying to a Z boson and an electron or a muon is presented. The search is based on pp collision data taken at root s = 8TeV by the ATLAS experiment at the CERN Large Hadron Collider, corresponding to an integrated luminosity of 20.3 fb(-1). Three high-transverse-momentum electrons or muons are selected, with two of them required to be consistent with originating from a

Proton therapy has shown potential for reducing doses to normal tissues in breast cancer radiotherapy. However data on the impact of protons when including internal mammary nodes (IMN) in the target for breast radiotherapy is comparatively scarce. This study aimed to evaluate normal tissue doses when including the IMN in regional RT with scanned proton beams, with and without respiratory gating. T

Purpose: The substantial literature showing that offspring of parents with alcohol use disorder (AUD) is at increased risk for externalizing psychopathology rarely examines the differential effects of parental and offspring sex. This literature also has other important limitations, such as modest sample sizes and use of unrepresentative samples. Using a large, nationwide Swedish sample, we aim to

Gene expression (GE) signatures and Tumor Infiltrating Lymphocytes (TIL) enumeration are predictive for response to neoadjuvant chemotherapy in HR- and in HER2+ breast cancer, but data are conflicting in HR+/HER2- disease. This study aimed to explore their predictive value in this subset, measured both at baseline and after short exposure to chemotherapy. Specifically, the PROMIX phase 2 trial enr

Sequencing of immunoglobulin germline gene loci is a challenging process, e.g. due to their repetitiveness and complexity, hence limiting the insight in the germline gene repertoire of humans and other species. Through next generation sequencing technology, it is possible to generate immunoglobulin transcript data sets large enough to computationally infer the germline genes from which the transcr

Objectives We compared the effectiveness of an intensive smoking cessation intervention among smokers with and without a severe mental disorder (SMD) and identified factors associated with successful quitting. The main hypothesis was that smokers with an SMD would be less likely to stay continuously smoke-free for 6 months. Design A prospective cohort study. Setting In all, 302 smoking cessation c

A search for the bb decay of the Standard Model Higgs boson produced through vector-boson fusion is presented. Three mutually exclusive channels are considered: two all-hadronic channels and a photon-associated channel. Results are reported from the analysis of up to 30.6 fb-1 of pp data at s=13 TeV collected with the ATLAS detector at the LHC. The measured signal strength relative to the Standard
