Objective - To investigate the feasibility of monophasic action potential ( MAP) mapping using an electro-anatomical mapping system ( CARTO) in obtaining information on global dispersion of atrial repolarization and to evaluate the role of dispersion of repolarization in the genesis of paroxysmal atrial fibrillation ( PAF). Methods and results - Right atrial MAPs were recorded from 53 +/- 18 sites
Background: Some improvement has been seen in survival after cardiac arrest but the outcome is still poor and 50-70% of patients do not survive despite successful return of spontaneous circulation (ROSC). The cause of death is multifactorial. The majority of patients die from brain injury, but up to 35% die as a result of circulatory failure. Purpose: First, to investigate the release profiles
Coastal hypoxia is increasing in the global coastal zone, where it is recognized as a major threat to biota. Managerial efforts to prevent hypoxia and achieve recovery of ecosystems already affected by hypoxia are largely based on nutrient reduction plans. However, these managerial efforts need to be informed by predictions on the thresholds of hypoxia (i.e. the oxygen levels required to conserve
Temperature not only has direct effects on microbial activity, but can also affect activity indirectly by changing the temperature dependency of the community. This would result in communities performing better over time in response to increased temperatures. We have for the first time studied the effect of soil temperature (5-50 degrees C) on the community adaptation of both bacterial (leucine in
Bell's palsy is an acute unilateral weakness or paralysis of the face of unknown cause. The incidence of the disease is 30 individuals per 100,000 per year. It is a diagnosis of exclusion and other known causes for acute peripheral facial palsy must be ruled out. The prognosis is overall favorable and about 70% of the patients recover completely within 6 months without treatment. Recent randomized
Aims: A study was undertaken to investigate the relationship between country of birth, time in Sweden, and overweight and obesity. Methods: Approximately 4,000 people aged 20-80 participated in a cross-sectional survey in 1994. The ethnic differences in overweight and obesity were analysed in a multivariate logistic regression analysis adjusting for age and education. The effect of number of years
76 patients were examined clinically and radiologically 27 to 36 years after a fracture of the distal radius. The average age was 31 years at the time of injury and 63 years at follow-up. In 81% of the patients there was no difference between the fractured and the non-fractured side. No patient had to change his or her occupation or leisure activities because of the fracture. There were more degen
Within administrative surveying work in Sweden, a transition to a client-centered team-based organization was made during 1998. The aim of this study was to describe the employees’ perceptions and expectations of job and organizational practices when working as a generalist in a client-centered team-based organization; job and organizational practices and well-being and effectiveness measures were
Real-time monitoring of patient’s blood metabolites, such as glucose and lactate, could potentially improve surgery and recovery outcomes for patients in surgical and intensive care units. Our enzyme thermometric biosensor which is based on flow injected calorimetric determination of immobilized enzyme reaction is capable of performing continuous, fast, and quantitative analysis of metabolites usi
Our contemporary time is haunted by fabricated stories or so called “fake news”. Some of them are threatening the long-term work to promote health carried out by bodies, such as the WHO. The origin of human immunodeficiency virus (HIV) being a contamination and a mutation originating from primates is well-documented. Despite this well documented fact, alternative narratives are often being heard o
Nanowire solar cells are a promising candidate for future photovoltaic applications as they promise the high efficiency of thin film III-V semiconductor solar cells while simultaneously keeping the costs low, due to reduced material consumption. In order to progress towards this direction, further understanding is needed to optimize the power conversion efficiencies of nanowire single junction sol
This paper provides evidence on the causal relationship between education and poverty. I construct a novel database comprising compulsory schooling reforms in 32 European countries and use them as instruments for education. I find economically large poverty-reducing effects of education among people aged 30 to 80. This holds true for both objective measures of poverty (relative income poverty, lac
Left ventricular assist devices (LVADs) have dramatically improved short-term outcomes among patients with advanced heart failure. While neurohormonal blockade (NHB) is the cornerstone of treatment for patients with heart failure with reduced ejection fraction, its effect after LVAD placement has not been established. We reviewed medical records of 307 patients who underwent primary LVAD implantat
Purpose – The purpose of this paper is to explore, describe and categorise practices of managing product returns empirically in internet retailing.Design/methodology/approach – A multiple case study was conducted involving 12 e-commerce firms and 4 logistics service providers. An integrative data collection approach of semi-structured interviews, documentation and observations was used to gain com
We have analyzed decade-long methane flux data set from a boreal fen, Siikaneva, together with data on environmental parameters and carbon dioxide exchange. The methane flux showed seasonal cycle but no systematic diel cycle. The highest fluxes were observed in July–August with average value of 73 nmol m−2 s−1. Wintertime fluxes were small but positive, with January–March average of 6.7 nmol m−2 s
Objective: To study whether locally administered recombinant inactivated human coagulation factor VIIa (FFR-rFVIIa) would reduce the thrombus formation and improve patency in an experimental venous thrombosis model without inducing systematic changes in the coagulation. Design: Experimental double-dummy randomised study. Materials: In 20 healthy New Zealand White rabbits both juguIar veins were ex
Loss and fragmentation of semi-natural grasslands have had negative consequences for grassland biodiversity, such as butterflies. Urban parks and other urban green spaces have so far largely been overlooked as suitable butterfly habitats, although they could potentially sustain diverse butterfly populations over time. We analysed the temporal change in butterfly species assemblages in urban green
Background: The rising prevalence of obesity represents an important public health issue. An assessment of its costs may be useful in providing recommendations for policy and decision makers. This systematic review aimed to assess the economic burden of obesity and to identify, measure and describe the different obesity-related diseases included in the selected studies. Methods: A systematic liter
