Are video-urodynamics superior to traditional urodynamic studies in changing treatment decision with urinary symptoms?

: To investigate the utility of video-urodynamic studies (VUDS) in patients with various urinary conditions and to evaluate if the addition of fluoroscopic imaging changes the treatment plans one would pursue if urodynamic studies (UDS) alone were performed as VUDS increases cost, radiation exposure, and patient discomfort. : A retrospective chart review was conducted on all women who underwent VUDS from 2013 to 2015 at one institution. We hypothesised that the addition of the fluoroscopic images would not change the treatment plan.

Patient-Reported Outcome Measures (PROMs) in Pelvic Floor Disorders.

Purpose Of Review: Patient-reported outcome measures (PROMs) are tools that are widely used by clinicians and researchers across different medical specialties. In this review, we examine the use of PROMs in the evaluation of female pelvic floor disorders (PFD).

Recent Findings: PROM development in the assessment of urinary incontinence is more advanced than other pelvic disorders.

Acid ceramidase upregulation in prostate cancer cells confers resistance to radiation: AC inhibition, a potential radiosensitizer.

Radiation resistance in a subset of prostate tumors remains a challenge to prostate cancer radiotherapy. The current study on the effects of radiation on prostate cancer cells reveals that radiation programs an unpredicted resistance mechanism by upregulating acid ceramidase (AC). Irradiated cells demonstrated limited changes of ceramide levels while elevating levels of sphingosine and sphingosine-1-phosphate.

Acid ceramidase inhibition: a novel target for cancer therapy.

During the last decade, sphingolipid deregulation, namely the balance between the pro-apoptotic molecule ceramide and the anti-apoptotic sphingolipid sphingosine-1-phosphate, has emerged as an important factor in cancer pathology and resistance to therapy. Thus, our research has been focused on developing drugs that are able to restore normal sphingolipid balance, precisely through increasing the levels of ceramide and decreasing sphingosine-1-phosphate. Particularly, inhibition of the ceramide metabolizing enzyme acid ceramidase, whose over-expression in cancer cells has been implicated in resistance to treatment, is proving to be an efficient and promising strategy.

The functional effects of acid ceramidase overexpression in prostate cancer progression and resistance to chemotherapy.

Among the many processes regulating cell death, ceramide signaling is a vital component. We previously determined that acid ceramidase (AC) is upregulated in 60% of primary prostate cancer (PCa) tissues, suggesting that AC may play a role in tumor development. In order to determine the significance of AC elevation, stable clones of DU145 cells with AC overexpression (AC-EGFP) were generated.

Role of acid ceramidase in resistance to FasL: therapeutic approaches based on acid ceramidase inhibitors and FasL gene therapy.

Head and neck squamous cell cancers (HNSCC) are particularly aggressive and are resistant to many forms of treatment. Ceramide metabolism has been shown to play an important role in cancer progression and cancer resistance to therapy in many tumor models, including HNSCC. Here, we study the role of the ceramide-metabolizing enzyme acid ceramidase (AC) in therapeutic responses in HNSCC.
