Intrarenal hypoxia has been suggested a unifying pathway to chronic kidney disease (CKD) and increased mitochondria leak respiration, which increases mitochondrial oxygen usage and is one important mechanism contributing to the development of the hypoxia. Previous studies indicate that angiotensin II (Ang II) effects on mitochondria function could be dose dependent. We investigated how moderate and high levels of Ang II affect kidney mitochondria function and pathways of leak respiration. ⋯ In conclusion, Ang II dose-dependently affects mitochondrial function and leak respiration. Thus, Ang II has the potential to directly affect cellular metabolism during conditions of altered Ang II signaling.

Review Meta Analysis
Stand-alone virtual reality exposure therapy as a treatment for social anxiety symptoms: a systematic review and meta-analysis.
Social anxiety is common and can have far-reaching implications for affected individuals, both on social life and working performance. Usage of virtual reality exposure therapy (VRET) has gained traction. The aim of the present systematic review was to evaluate the effect of stand-alone VRET on social anxiety symptoms. ⋯ Stand-alone VRET may reduce social anxiety symptoms. However, despite promising results, there is still uncertainty as the effect estimate is based on few studies with few participants each and a high risk of bias.

Randomized Controlled Trial
No effects on heart rate variability in depression after treatment with dorsomedial prefrontal intermittent theta burst stimulation.
The purpose of this study was to investigate whether treatment of a depressive episode with intermittent theta burst stimulation (iTBS) over the dorsomedial prefrontal cortex (DMPFC) had any effects on heart rate variability (HRV). We also investigated if changes in HRV covaried with symptom change after iTBS and if HRV could predict symptom change. ⋯ Treatment for depression with dorsomedial iTBS had neither negative nor positive effects on the cardiac autonomic nervous system.

The esophageal-tracheal Combitube (ETC) was developed for the management of difficult airways but can also be used for general anaesthesia. ⋯ We conclude that the Combitube may be used for short procedures requiring general anaesthesia, but the high rate of minor complications limits its value when other alternatives such as a laryngeal mask airway are available. The tested method appears safe regarding major complications, but minor complications are common. Adherence to recommended cuff volumes, experience with the ETC and limiting its use to surgeries lasting less than 2 h might reduce the rate of complications.
