Background: Primary indication for catheter ablation of atrial fibrillation (AF) is to reduce symptoms and improve health-related quality of life (HRQoL). There are data showing differences between the genders and between younger and older patients. To evaluate this, we studied a large Scandinavian cohort of patients referred for catheter ablation of AF. Methods: Consecutive patients filled out th
Recent warming in the Arctic, which has been amplified during the winter1–3, greatly enhances microbial decomposition of soil organic matter and subsequent release of carbon dioxide (CO2)4. However, the amount of CO2 released in winter is not known and has not been well represented by ecosystem models or empirically based estimates5,6. Here we synthesize regional in situ observations of CO2 flux f
Background: Medical advancements have resulted in better survival and life expectancy among those with spina bifida, but a significantly increased risk of perinatal and postnatal mortality for individuals with spina bifida remains. Objectives: To examine stillbirth and infant and child mortality among those affected by spina bifida using data from multiple countries. Methods: We conducted an obser
During the few past decades, intensive efforts have been focused toward optimizing ‘wiring’ of thylakoid membranes (TMs) to conductive surfaces for their further application for light-energy conversion and production of an electron flow. This review summarizes recent progress and current state of photobioelectrodes and systems based on TMs. We consider various electrode materials and surface modif
The self-assembly of small colloidal clusters, so-called colloidal molecules, into crystalline materials has proven extremely challenging, the outcome often being glassy, amorphous states where positions and orientations are locked. In this paper, a new type of colloidal molecule is therefore prepared, assembled from poly(N-isopropylacrylamide) (PNIPAM)-based microgels that due to their well docum
Wastewater treatment and subsequent effluent recycling for non-drinking purposes such as irrigation contributes to the mitigation of the pressure on freshwater resources. In this study, two vertical sub-surface flow constructed wetland (VSSF-CW) pilot plants were operated to treat municipal wastewater and their effluents were reused for irrigation purposes. One of the wetlands was vegetated with P
The experimental methodology achieved in the present study signified that the adsorption and precipitation were main mechanisms occurred together in the removal of nickel from aqueous solution by sorption using cement kiln dust (CKD) byproduct as sorbent. Finding the contribution of each mechanism in the removal process and derivation an analytical model for finding the portion of precipitation we
OBJECTIVE: To assess the effects of different durations of simulated microgravity exposure on ventricular repolarization (VR) in terms of T-wave alternans (TWA) as well as to test whether an increase in VR heterogeneity could be detected once normal gravity was restored. APPROACH: A total of 63 healthy volunteers were recruited in several head-down bed-rest (HDBR) experiments in the context of the
In regions where sunlight exposure is limited, dietary vitamin D intake becomes important for maintaining status. However, Swedish children have been shown to have deficient or marginal status during the winter months even if the recommended dietary intake is met. Since low vitamin D status has been associated with several disease states, this study investigated the metabolic changes associated wi
Biomolecule derivatives are transversally used in nanotechnology. Deciphering their aggregation behavior is a crucial issue for the rational design of functional materials. To this end, it is necessary to build libraries of selectively functionalized analogues and infer general rules. In this work we enrich the highly applicative oriented collection of steroid derivatives, by reporting a rare exam
OBJECTIVE: To assess the impact of the Swedish health authority recommendation against the use of knee arthroscopy in patients aged ≥40 years with knee osteoarthritis (OA).DESIGN: Interrupted time series analysis.SETTING: Public health care in Skåne region.PARTICIPANTS: Patients aged ≥40 years who underwent knee arthroscopy from January 2010 to December 2015.INTERVENTION(S): National guideline's r
Objective: To determine the nationwide prevalence of primary dystonia, ataxia and hereditary spastic paraplegia (HSP) in Sweden. Methods: We extracted data on all patients who were registered in The National Patient Register (NPR) in Sweden (population 9.64 million) at least twice during five consecutive years with a diagnosis of primary dystonia, ataxia or HSP. We excluded patients with an additi
As a result of an increasing number of bacteria developing resistance against antibiotics, antimicrobial peptides (AMPs) are attracting significant interest, particularly in relation to identification of peptides displaying potent but selective effects. Much less focus has been placed on delivery systems for AMPs, despite AMPs suffering from delivery challenges related to their size, cationicity,
Mnemonic discrimination, the ability to distinguish similar events in memory, relies on subregions in the human medial temporal lobes (MTLs). Tau pathology is frequently found within the MTL of older adults and therefore likely to affect mnemonic discrimination, even in healthy older individuals. The MTL subregions that are known to be affected early by tau pathology, the perirhinal-transentorhina
Study region: Rukarara River Watershed (RRW), Rwanda. Study focus: DOC leaching has important environmental consequences for both terrestrial and aquatic ecosystems. This paper measures leached dissolved organic carbon (LDOC) and the factors controlling its variation in the RRW, a mixed agriculture and forest watershed in Rwanda. The study describes the relationship of LDOC with land use/land cove
OBJECTIVE: To explore stroke survivors' experiences of healthcare-related facilitators and barriers concerning return to work after stroke. DESIGN: A qualitative study. SETTING: Outpatient stroke rehabilitation unit at a University Hospital in southern Sweden. PARTICIPANTS: A convenient sample of 20 persons admitted to Skåne University Hospital for acute stroke care (median age 52 years), in emplo
The incidence of stroke and dementia are diverging across the world, rising for those in low-and middle-income countries and falling in those in high-income countries. This suggests that whatever factors cause these trends are potentially modifiable. At the population level, neurological disorders as a group account for the largest proportion of disability-adjusted life years globally (10%). Among
Background: Sweden is a major host nation for asylum-seeking immigrants, and residential placement of these immigrants is an important policy concern. This quasi-experimental study estimated of the impact of being placed into an “immigrant enclave” on risk of officially-recognized drug involvement (ORDI) among asylum-seeking immigrants over a 15-year period. Methods: All data come from Swedish reg
Background: Few studies have investigated the effect of hydration status on appetite for food in healthy adults. Prior work suggests hydration status does not alter appetite or energy intake, with mixed findings regarding appetite hormone secretion. However, an extensive investigation into both the psychological and physiological appetitive responses to hydration status has never been conducted. O
