Feasibility of implementing current best clinical practice for people who are using anabolic androgenic steroids within a Swiss primary care practice: a quality assurance study.

Background: The non-medical use of anabolic androgenic steroids for the improvement of aesthetic and sports performance purposes has become a global substance use disorder, particularly among men in recreational sports. Health outcomes among people who are using anabolic androgenic steroids may be detrimental, yet healthcare services for these users are scarce. Therefore, the aim of this project was to conduct a quality assurance study to evaluate the feasibility of providing current best clinical practice for anabolic androgenic steroids users based on the published literature within a primary care practice in Zurich (Switzerland).

[Primary neuroendocrine tumor of the kidney. A rarity].

This article presents a rare case of a primary neuroendocrine tumor (NET) of the kidney. Abdominal magnetic resonance imaging (MRI) was performed in a 56-year-old man during the follow-up of an adrenal adenoma. Incidentally a renal tumor at the upper pole of the left kidney was diagnosed and was suspected of being a renal cell carcinoma.

Differential effects of visual feedback on subjective visual vertical accuracy and precision.

The brain constructs an internal estimate of the gravitational vertical by integrating multiple sensory signals. In darkness, systematic head-roll dependent errors in verticality estimates, as measured by the subjective visual vertical (SVV), occur. We hypothesized that visual feedback after each trial results in increased accuracy, as physiological adjustment errors (A-/E-effect) are likely based on central computational mechanisms and investigated whether such improvements were related to adaptational shifts of perceived vertical or to a higher cognitive strategy.
