Objective:Nutraceutical products are widely used for their claimed therapeutic benefits.However,falsified or adulterated nutraceuticals present a major health threat to consumers.This study investigates the pharmaceutical quality,safety and anti-inflammatory effects of six male enhancement nutraceuticals that claim to be 100%natural.Methods:Three batches of six male enhancement products were tested to detect the presence and levels of adulterants via high-performance liquid chromatography(HPLC).The pharmaceutical quality of the selected nutraceuticals was tested with near infrared spectroscopy(NIR)and Se De M.The cytotoxic effects of these products on HepG2 cells were determined through cell proliferation(XTT)and lactate dehydrogenase(LDH)cytotoxicity assays.Lastly,the in vitro inflammatory effects of these products were investigated using murine J774 macrophages through cytokine release analysis.Results:HPLC analysis detected the presence of sildenafil citrate,a vasodilator,and the active ingredient in Viagra and Revatio,in all batches of the products we analyzed.Amount of sildenafil citrate ranged from 0.45 mg to 51.85 mg among different batches.NIR assessment showed inter-and intra-batch heterogeneity in product composition.Results of the XTT and LDH assays showed significant cytotoxic effects of the analyzed products.XTT analysis revealed that the viability of HepG2 treated with tested products varied from 27.57%to 41.43%.Interestingly,the male enhancement products also showed anti-inflammatory effects.Conclusion:Despite their labeling as 100%natural,all products tested in this study contained levels of sildenafil citrate,which was not reported on the packaging.There was a lack of pharmaceutical uniformity among products of the same batch and across different batches.Additionally,the products we tested had cytotoxic effects.These study findings highlight the adulteration,poor quality and hazard of these nutraceuticals.Therefore,strict regulation of these products and standardization of the definition of nutra

AIM To evaluate the value of pre-treatment 18F-FDG PET/CT in patients with HCC following liver radioembolization.METHODS We identified 34 patients with HCC who underwent an FDG PET/CT scan prior to hepatic radioembolization at our institution between 2009 and 2013. Patients wereseen in clinic one month after radioembolization and then at 2-3 mo intervals. We assessed the influence of FDG tumor uptake on outcomes including local liver control(LLC), distant liver control(DLC), time to distant metastases(DM), progression free survival(PFS) and overall survival(OS).RESULTS The majority of patients were males(n = 25, 74%), and had Child Pugh Class A(n = 31, 91%), with a median age of 68 years(46-84 years). FDG-avid disease was found in 19(56%) patients with SUVmax ranging from 3 to 20. Female patients were more likely to have an FDG-avid HCC(P = 0.02). Median follow up of patients following radioembolization was 12 months(1.2-62.8 mo). FDG-avid disease was associated with a decreased 1 year LLC, DLC, DM and PFS(P < 0.05). Using multivariate analysis, FDG avidity predicted for LLC, DLC, and PFS(all P < 0.05).CONCLUSION In this retrospective study, pre-treatment HCC FDGavidity was found to be associated with worse LLC, DLC, and PFS following radioembolization. Larger studies are needed to validate our initial findings to assess the role of F-18-FDG PET/CT scans as biomarker for patients with HCC following radioembolization.
