Objectives: The aim of this study was to investigate the potential impact of gestational age (GA) estimation on the basis of the last menstrual period (LMP) in comparison with GA based on ultrasound examination on rates of survival and neonatal morbidity among extremely preterm infants. Methods: The Swedish national registry of infants born extremely preterm (Extremely Preterm Infants in Sweden St
We report on the measurement of two-pion correlation functions from pp collisions at root s = 900 GeV performed by the ALICE experiment at the Large Hadron Collider. Our analysis shows an increase of the Hanbury Brown-Twiss radius with increasing event multiplicity, in line with other measurements done in particle- and nuclear collisions. Conversely, the strong decrease of the radius with increasi
The phase behavior of amphiphiles, e.g., lipids and surfactants, at low water content is of great interest for many technical and pharmaceutical applications. When put in contact with air having a moderate relative humidity, amphiphiles often exhibit coexistence between solid and liquid crystalline phases, making their complete characterization difficult. This study describes a (13)C solid-state N
To develop and validate a biomarker-based index to optimize referral and diagnosis of patients with suspected ovarian cancer. Furthermore, to compare this new index with the Risk of Malignancy Index (RMI) and Risk of Ovarian Malignancy Algorithm (ROMA).
Changes in the tropical hydrological cycle have been recorded world wide in speleothem records dating back more than 200,000 years for some areas. Numerous empirical and modelling studies have demonstrated a strong link between the intensity of the northern hemisphere monsoon and the precessional insolation cycle (similar to 23 ka (thousand years)). Here we present simulations of the climate condi
At the LHC all processes are QCD ones, whether 'signal' or 'background'. In this review the frontiers of current QCD research are addressed, towards increased understanding, improved calculational precision, and role in potential future discoveries. Issues raised include: the limits of perturbative QCD calculations and parton distribution usage, the nature of multiparton interactions, the impact o
Background: Necrotizing fasciitis is a soft tissue infection characterized by rapid progression and a high mortality rate. The objective of this study was to investigate diagnosis, causative microbial agents, comorbidities, antibiotic regimen and outcome regarding this disease at Skåne University Hospital in Malmö, Sweden. Methods: From medical records, we identified 33 patients treated from Janua
Early exiting from the labor force and into disability pension (DP) represents a major social problem in Sweden and elsewhere. We examined how being asymmetric (A-SGA) or symmetric (S-SGA) small for gestational age predicts transitioning into DP. We analyzed a longitudinal sample of 8125 men and women from the Stockholm Birth Cohort (SBC), born in 1953 and not on DP in 1990. The SBC consists of da
The emotional salience of faces has previously been shown to induce memory distortions in recognition memory tasks. This event-related potential (ERP) study used repeated runs of a continuous recognition task with emotional and neutral faces to investigate emotion-induced memory distortions. In the second and third runs, participants made more false alarms to distracters (repeated from previous ru
Warfarin treatment discontinuation is significant among patients with atrial fibrillation (AF). For AF patients with stroke a warfarin persistence rate of 0.45 after 2years has previously been reported. No consistent predictors for discontinuation have been established.
The balance between self-renewal and differentiation is crucial for the maintenance of hematopoietic stem cells (HSCs). Whereas numerous gene regulatory factors have been shown to control HSC self-renewal or drive their differentiation, we have relatively few insights into transcription factors that serve to restrict HSC differentiation. In the present work, we identify ETS (E-twenty-six)-related
During the last five decades, survival of childhood cancer has increased from 25% to 80%. At the same time, however, it has become evident that survivors experience a broad range of therapy-related late adverse health effects. The aim of the Adult Life after Childhood Cancer in Scandinavia (ALiCCS) study is to investigate long-term health consequences of past and current therapies in order to impr
Forest carbon cycles play an important role in efforts to understand and mitigate climate change. Large amounts of carbon (C) are stored in deep mineral forest soils, but are often not considered in accounting for global C fluxes because mineral soil C is commonly thought to be relatively stable. We explore C fluxes associated with forest management practices by examining existing data on forest C
Carcinogenic aromatic amines derived from hair dyes have recently received new attention. One of these is ortho (o)-toluidine, which is classified as carcinogenic to humans.
The outcome of management of diabetic foot ulcers is poor, and there is continuing uncertainty concerning optimal approaches to management. It was for these reasons that in 2006 the International Working Group of the Diabetic Foot (IWGDF) working group on wound healing undertook a systematic review of the evidence to inform protocols for routine care and to highlight areas which should be consider
Chronic pulmonary disease is a recognized risk factor for invasive pneumococcal disease (IPD). However, previous studies have often not been large enough to allow detailed analyses of less prevalent pulmonary diseases, and findings regarding case fatality have been inconsistent. We examined the associations between an underlying pulmonary disease and IPD, and the impact of these diseases on the ca
The human antimicrobial peptide cathelicidin LL-37 has, besides its antimicrobial properties, also been shown to regulate apoptosis in a cell type-specific manner. Mechanisms involved in LL-37-regulated apoptotic signaling are not identified. Here, we show that LL-37 reduces the human osteoblast-like MG63 cell number and cell viability in the micromolar concentration range with an IC(50) value of
The purpose of this work is the development, identification and validation of a model for the simulation of a thermomechanical multistage production process chain for sheet steels. The process of interest consists of forming (in particular deep-drawing) followed by cutting and heat treatment. For the forming and cutting stages, the complete model is based in particular on a model for thermoelastic
