Background: Childhood constipation is increasingly common, yet its prevalence is uncertain. This study examines comprehensive national data for trends in medically treated childhood constipation over a period of 18 years.Methods: Included were all Swedish children, 0-14 years, 2006-2023, and all prescriptions for constipation, using the national Swedish Prescribed Drug register.

To investigate if left and right atrioventricular plane displacement (AVPD) or regional contributions to SV are prognostic for outcome in patients with pulmonary arterial hypertension (PAH). Seventy-one patients with PAH and 20 sex- and age-matched healthy controls underwent CMR. Myocardial borders and RV insertion points were defined at end diastole and end systole in cine short-axis stacks to co

To meet and work with teenagers may be a challenge for caregivers as adolescence is a period when youths try to establish autonomy. Although asthma is an increasing problem worldwide, few studies have addressed professional caregivers' motives and actions. Therefore, the aim of this study was to describe professional caregivers' strategies in their work with teenagers with asthma. Grounded theory,

Different radiological methods play an important role in the work-up of patients complaining of spine pain. Depending on the symptoms and the suspected underlying etiology different methods are selected. In the following presentation we briefly present the different radiological and magnetic resonance tomography methods that are at hand, give some guidance in which method to use, and present the t

The overall aims of this thesis were to improve prediction, diagnostics and knowledge on epidemiology of sepsis. In paper I, we developed and evaluated an integrated platform for rapid analysis of sepsis-causing organisms directly from blood samples. Testing with blood samples spiked with bacteria and samples from septic patients indicate that the detection limit of the system is in the upper part

We present a low-complexity transceiver for ultrawideband communications with moderate (1-15 Mbit/s) data rate. This transceiver is based on time-frequency-interleaved frequency-shift-keying (TF-FSK), and shows a high degree of compatibility with multiband-OFDM, the currently envisioned standard for high-data-rate (>100 Mbit/s) UWB communications. We show that for dual-mode devices, the major part

Many machines and robots working today in factories are programmed to perform the same task repeatedly. By observing the tracking error in each iteration of the same task it becomes clear that it is actually repetitive, even though disturbances from noise and possibly sligthly changing friction dynamics affect the response. The idea of Iterative learning Control D ILC E is to use the knowledge fro

Histatins are a family of human salivary peptides which act as a part of the innate immune system. There are three main members of the family: Histatin 1 (Hst1), Histatin 3 (Hst3), and Histatin 5 (Hst5). Histatins have long been known to possess differing antimicrobial properties, such as antifungal and antiviral capabilities. Hst5 is generally described as the most potent antifungal peptide in th

As the EU considers tougher rules for returning asylum seekers who had their applicationrejected, more people might be placed in detention and the possibility of voluntary returncould be limited

Many control objectives can be expressed in terms of a criterion function. Generally, explicit solutions to such optimization problem require full knowledge of the plant and disturbances and complete freedom in the complexity of the controller. In practice, the plant and the disturbances are seldom known, and it is often desirable to achieve the best possible performance with a controller of presc

A novel integrated approach to high-accuracy machining with industrial robots is presented in this paper. By combining a conventional industrial robot with an external compensation mechanism, a significantly higher bandwidth of the control of the relative position between the tool and the workpiece can be achieved. A model-based feedback controller for the compensation mechanism, as well as a mid-

Are you worried about the climate and biodiversity crises and related events like heavy rainfalls and floods, high carbon emissions, sudden heat waves, or loss of species? Are you already doing something to help solve these problems? To reduce flood risks, we can give rivers more space by reconnecting floodplains. To store carbon and help to slow down climate change, we can protect and establish w
