Muscle wasting is common in patients with chronic kidney disease (CKD). Many studies report that mitochondrial dysfunction and endoplasmic reticulum (ER) stress are involved in the development of muscle wasting. However, treatment approaches to protect against muscle wasting are limited. In this study, we investigated the benefits and potential mechanism of Mito-TEMPO, a mitochondria-targeted antioxidant on uremic-induced muscle wasting. ⋯ Mito-TEMPO improved muscle wasting in CKD mice possibly through alleviating mitochondrial dysfunction and endoplasmic reticulum stress, providing a potential new therapeutic approach for preventing muscle wasting in chronic kidney disease.

Effect of mirtazapine on pruritus in patients on hemodialysis: a cross-over pilot study.
Uremic pruritus (UP) is a highly prevalent and disturbing problem in patients with advanced chronic kidney disease (CKD); however, treatment of UP is largely unsatisfactory. The present study was designed to investigate the effectiveness of mirtazapine, an atypical antidepressant agent with potent antagonistic activity against serotonin (5HT2, 5HT3) and histamine (H1) receptors, in the treatment of pruritus in hemodialysis (HD) patients. ⋯ Although preliminary, our study provides evidence that mirtazapine can be an effective therapy for UP in patients who are on maintenance HD. However, further studies would be necessary to confirm effectiveness as well as the safety of mirtazapine in the long-term management of chronic pruritus.

To evaluate the association of intravesical prostatic protrusion (IPP) and overactive bladder (OAB) in male patients with lower urinary tract symptoms (LUTS). IPP has been suggested to correlate with storage symptoms in addition to bladder outlet obstruction. ⋯ IPP is not a good predictor of OAB in men presenting with LUTS. However, grade 3 IPP indicates higher frequency of nocturia.

Our aim was to identify the independent prognostic factors in patients with primary urethral carcinoma (PUC) and to predict their overall survival (OS) and cancer-specific survival (CSS) at 3, 5, and 8 years. ⋯ We developed and validated nomograms for predicting OS and CSS in patients with PUC, which can help clinicians make treatment decisions.
