Socioeconomic inequalities and infant mortality of 46 470 preterm infants born in Sweden between 1992 and 2006. Paediatric and Perinatal Epidemiology 2011; 25: 357-365. Studies on possible sociodemographic inequities in the survival of preterm infants are scarce. Individual and neighbourhood sociodemographic factors are related to preterm birth and to infant mortality in full-term infants. The aim

Background: Adenocarcinomas of the rectum shed viable cells, which have the ability to implant. Intraoperative rectal washout decreases the amount and viability of these cells, but there is no conclusive evidence of the effect of rectal washout on local recurrence after rectal cancer surgery. Methods: Data were analysed from a population-based registry of patients who had anterior resection from 1

Recent reforms in Swedish primary care have involved choice of provider for the population combined with freedom of establishment and privatisation of providers. This study focus to what extent individuals feel they have exercised a choice of provider, why they exercise choice and where they search for information, based on a population survey in three Swedish counties. The design of the study ena

The individual prognosis of infants with atopic dermatitis (AD) is important for parents, healthcare professionals, and society. The aim of this study was to investigate predictors for remission of infant AD until school age. A systematic review was carried out of clinical and epidemiological studies investigating the effect of filaggrin gene (FLG) loss-of-function mutations, sex, exposure to pets

The cerebellum is classically considered to be mainly involved in motor processing, but studies have suggested several other functions, including pain processing. Calcitonin-gene-related peptide (CGRP) is a neuropeptide involved in migraine pathology, where there is elevated release of CGRP during migraine attacks and CGRP receptor antagonists have antimigraine efficacy. In the present study, we e

Several valuable substances are released from wood during the production of thermomechanical pulp. These substances can be isolated and purified for use as value-added chemicals. The hemicellulose galactoglucomannan (GGM) has attracted a great deal of interest because of its possible applications as an oxygen barrier film in packaging materials, as a hydrogel in biomedical products and as an emuls

Determining climate change feedbacks from tropical rainforests requires an understanding of how carbon gain through photosynthesis and loss through respiration will be altered. One of the key changes that tropical rainforests may experience under future climate change scenarios is reduced soil moisture availability. In this study we examine if and how both leaf photosynthesis and leaf dark respira

Depressive personality disorder (DPD) is highly studied and common in clinical settings. Nevertheless, it is rife with controversies and often overshadowed by major depression and dysthymia with which it shares many similarities but also is clinically distinct. Possibly as a result, DPD is underdiagnosed and misunderstood in clinical care. Thus the goal of this practice review is to present a case

Human land use changes perturb biogeochemical silica (Si) cycling in terrestrial ecosystems. This directly affects Si mobilisation and Si storage and influences Si export from the continents, although the magnitude of the impact is unknown. A major reason for our lack of understanding is that very little information exists on how land use affects amorphous silica (ASi) storage in soils. We have qu

In 728 Swedish cases of monoclonal gammopathy of undetermined significance (MGUS), followed up to 30 years (median 10 years), we estimated the cumulative risk of hematologic disorders originating from lymphoid and myeloid lineages. Using Cox regression models, we examined associations of demographic and laboratory factors with progression and determined the discriminatory power of three prediction

In adipocytes, lipolysis is a highly regulated process involving hormonal signals, lipid droplet-associated proteins, and lipases. The discovery of new lipid droplet-associated proteins added complexity to the current model of lipolysis. In this study, we used cultured human adipocytes to demonstrate that fat-specific protein 27 (FSP27), an abundantly expressed protein in adipocytes, regulates bot

Insulin resistance results in compensatory increase in insulin secretion to maintain normoglycemia. Conversely, high insulin sensitivity results in reduced insulin secretion to prevent hypoglycemia. The mechanisms for this inverse adaptation are not well understood. We utilized highly insulin sensitive mice, due to adipocyte specific overexpression of the FOXC2 transcription factor, to study mecha

Collagen IX containing the N-terminal non-collagenous domain 4 (NC4) domain is unique to cartilage and a member of the family of fibril-associated collagens with both collagenous and non-collagenous domains. Collagen IX is located at the surface of fibrils formed by collagen II and a minor proportion of collagen XI, playing roles in tissue stability and integrity. The NC4 domain projects out from

The adsorption properties of water on the stoichiometric (101) surface of anatase TiO2 in the temperature range 160-400 K has been studied by synchrotron radiation core level photoelectron spectroscopy. O 1s spectra give clear evidence for the formation of a first layer of water that comprises both H2O and OH. The composition is 0.77 +/- 0.05 ML H2O and 0.47 +/- 0.05 ML OH. Decreasing the coverage

Combining pheromone trapping and genetic analyses can be useful whentrying to resolve complexes of closely related insect taxa that are difficult to distinguishbased on morphological characters. Nearctic and Palearctic populations of the spruceseed moth, Cydia strobilella L., have been considered taxonomically synonymoussince 1983, but more recent work revealing distinct sex pheromones for Canadia

The type I interferon system genes IKBKE and IFIH1 are associated with the risk of systemic lupus erythematosus (SLE). To identify the sequence variants that are able to account for the disease association, we resequenced the genes IKBKE and IFIH1. Eighty-six single-nucleotide variants (SNVs) with potentially functional effect or differences in allele frequencies between patients and controls dete

The forest, savanna, and grassland biomes, and the transitions between them, are expected to undergo major changes in the future due to global climate change. Dynamic global vegetation models (DGVMs) are very useful for understanding vegetation dynamics under the present climate, and for predicting its changes under future conditions. However, several DGVMs display high uncertainty in predicting v

A wide range of factors shapes irrigation institutions and collective action with regard to irrigation. They include the distribution of land across irrigation command areas and across classes, land tenure systems, access to new technology such as bore wells, the availability and cost of electricity and other energy sources for lifting groundwater, and, above all, state policies related to irrigat

Background: Terra preta do indio or 'dark earth' soils formed as a result of a long-term addition of organic matter by indigenous peoples in Amazonia. Aims: Here we report on the first study of productivity, allocation and carbon cycling from a terra preta plot in eastern Amazonia (Caxiuana, Para, Brazil), and contrast its dynamics with a nearby plot on infertile soil (ferralsols). Methods: We det
