Background: Postural orthostatic tachycardia syndrome (POTS) is a prevalent cardiovascular disorder after COVID-19 infection. Although POTS is characterized by the presence of sinus tachycardia, other hemodynamic disturbances including blood pressure (BP) regulation, remain largely unexplored.Aims: We investigated BP changes using 24-hour ambulatory-BP-monitoring in patients with new-onset POTS af

Background: Immigrants from the Middle East (ME) have a higher prevalence of type 2 diabetes (T2D) compared to the native-born Swedish population. In individuals free from T2D, ME immigrants are more insulin resistant and have lower levels of adjusted insulin secretion (Disposition index, DIo) compared to Swedish-born individuals. The ethnic differences are not fully explained by traditional risk

The paper presents some ideas and modeling approaches that are feasible for the study of socio-technical systems. The emphasis in the paper is to discuss two approaches concerning modeling of social and technical systems, and how they can be integrated in order to assess the vulnerability of a socio-technical system. The Swedish railway system will serve as the example of a socio-technical system

Popular Abstract in Swedish Att få inopererat en höft- eller knäprotes är numera ett vanligt ingrepp. Under 80-talet visade svenska och utländska studier att 10-15% av de patienter som genomgick en sådan höftoperation drabbades av försämrad njurfunktion efter operationen. Denna försämring var övergående men kunde vara allvarlig för patienten, och kostsam för sjukvården, under den tid den kvarstod.Total hip replacement (THR) is a common procedure, generally performed in elderly persons. Previous studies indicated that the use of isoxazolyl penicillins could induce a transient post-operative renal dysfunction in these patients. By measuring urinary levels of markers for glomerular (albumin, IgG) and tubular (protein HC) function we studied the influence of systemic cloxacillin, the gentamic

In recent years it has become increasingly clear that chemical interactions play a fundamental role in aquatic habitats and have far-reaching evolutionary and ecological consequences. A plethora of studies have shown that aquatic organisms from most taxa and functional groups respond to minute concentrations of chemical substances released by other organisms. However, our knowledge of this “chemic

Reliable electrical power supply is a requirement for the modern society, therefore it is important to analyse the vulnerability of the electric power system. Network analysis has previously been used to analyse the vulnerability of electric transmission systems, however recent events in Sweden have shown that perturbations in distribution systems also can cause severe societal consequences. Thus,

Popular Abstract in Swedish Cerebral pares (CP) drabbar drygt 2 barn per 1000 födda och är den vanligaste orsaken till rörelsehinder hos barn och ungdomar. På latin betyder CP "förlamning från hjärnan" och är ett samlingsnamn för ett följdtillstånd efter en skada i den omogna hjärnan under dess utveckling från fosterstadiet t o m 2-års ålder. Skadan är av engångskaraktär men de olika symtomen föräCerebral palsy (CP) is a term for a group of conditions associated with motor disabilities, that are very heterogeneous, i.e. symptoms, severity, associated impairments, functional outcome and needs. The overall purpose of this thesis was to study the prevalence and gross motor function and to evaluate and adapt measurements in children with CP. The prevalence in Southern Sweden was 2.4 per 1000 c

Two storms in Sweden 2005 and 2007 clarified both professional crisis managers and citizens' ability to respond to the consequences. These events created an awareness of the vulnerability of society, especially in rural areas. Emergent Citizen Groups (ECG) conducted initially a large part of crisis management, such as clearing roads, supporting exposed neighbors and repairing power lines in collab

We propose a method for identifying and ranking critical components and sets of components in technical infrastructures. Criticality is defined as the vulnerability of the system to failure in a specific component, or set of components. The identification of critical components is increasingly difficult when considering multiple simultaneous failures, especially component failures with synergistic

The most common form of technology for energy utilization via anaerobic treatment is slurry digestion with a low solids contents, such as sewage sludge or manure. Process control and maintenance are relatively simple, but costs involved with liquid handling and heating favour large, centralised plants. Raising the solids content of a digester to 30% significantly improves the economy of anaerobic

Phasor measurement signals are used as only input to a wide-area power system stabilizer to increase interarea mode damping of the Icelandic system. Modal analysis and time simulations of a detailed model show that frequency difference as PSS input gives a damping improvement that is robust to drastic changes in system topology. Field data from phasor measurement units indicate high signal quality
