Sensorless model-based tension control for a cable-driven exosuit.

Cable-driven exosuits have the potential to support individuals with motor disabilities across the continuum of care. When supporting a limb with a cable, force sensors are often used to measure tension. However, force sensors add cost, complexity, and distal components.

Secondary bile acid derivatives are contributors to the fecal bile acid pool and associated with bile acid modulating nutrients.

Objective: Accumulation of hydrophobic bile acids is linked with cancer development. However, derivatives of deoxycholic acid (DCA) and lithocholic acid (LCA) produced via bacterial metabolism may mitigate the proinflammatory and cytotoxic effects of hydrophobic bile acids. The impact of diet on secondary bile acid (BA) derivative production has not been determined.

Mineralocorticoid axis activity and cardiac remodeling in patients with ACTH dependent Cushing's syndrome.

Background: Arterial hypertension and left ventricular hypertrophy and remodeling are independent cardiovascular risk factors in patients with Cushing's syndrome. Changes in the renin-angiotensin system and in the mineralocorticoid axis activity could be involved as potential mechanisms in their pathogenesis, in addition to cortisol excess.

Methods: In this ancillary study of our previous study prospectively investigating patients with ACTH-dependent Cushing's syndrome by cardiac magnetic resonance imaging (NCT02202902), 11 patients without any interfering medication were cross-sectionally compared to 20 control subjects matched for age, sex and body mass index.

Diagnostic Accuracy of Lung and Abdominal Ultrasound for Tuberculosis in a German Multicenter Cohort of Patients With Presumed Tuberculosis Disease.

Background: There is limited evidence on point-of-care ultrasound for tuberculosis (TB), but studies suggest high sensitivity, especially for lung ultrasound (LUS). However, insufficient data are available on specificity of the examination and its generalizability to a broader patient population.

Aims: Our study aimed to establish accuracy for lung, chest, and abdominal ultrasound, individually and in combination, for TB diagnosis.
