The worldwide prevalence of psoriatic arthritis-a systematic review and meta-analysis.

Objectives: Previous attempts to pool prevalence studies in PsA have failed to take account of important methodological differences between studies which may have created biased estimates. The aim of this review is to estimate the prevalence of PsA within the adult general population worldwide, considering potential differences between population-based and health administrative studies separately.

Methods: Four electronic databases were systematically searched for articles reporting the prevalence of PsA.

Distinguishing between straight and curved sounds: Auditory shape in pitch, loudness, and tempo gestures.

Sound-based trajectories or sound gestures draw links to spatiokinetic processes. For instance, a gliding, decreasing pitch conveys an analogous downward motion or fall. Whereas the gesture's pitch orientation and range convey its meaning and magnitude, respectively, the way in which pitch changes over time can be conceived of as gesture shape, which to date has rarely been studied in isolation.

Hearing triangles: Perceptual clarity, opacity, and symmetry of spectrotemporal sound shapes.

In electroacoustic music, the spectromorphological approach commonly employs analogies to non-sonic phenomena like shapes, gestures, or textures. In acoustical terms, sound shapes can concern simple geometries on the spectrotemporal plane, for instance, a triangle that widens in frequency over time. To test the auditory relevance of such triangular sound shapes, two psychoacoustic experiments assessed if and how these shapes are perceived.

[Behavior of parameters of liver metabolism in intermediate-term use of the gestagen dienogest in the treatment of endometriosis].

The effects of the progestational compound dienogest (17 alpha-cyanomethyl-17 beta-hydroxy-estra-4,9-dien-3-one) on liver metabolism have been studied in 101 otherwise healthy women with endoscopically proven endometriosis. The women aged 17 to 45 years were treated with 2 mg dienogest in tablet form daily for 24 weeks. Aspartate amino transferase (ASAT), alanine amino transferase (ALAT), gamma glutamate transferase (GGT), alkaline phosphatase (AP), lactate dehydrogenase (LDH), and total bilirubin (BILI) were determined in serum before and after 1, 3 and 6 months use of the progestin.
