Fraud in nutritional supplements for athletes: a narrative review
Nutr Hosp. 2021 May 10. doi: 10.20960/nh.03413. Online ahead of print.ABSTRACTThe use of nutritional supplements (NSs) is a widespread practice in both professional and amateur athletes. Their choice must be based on criteria of safety, legality, and effectiveness. There are several risks that some of these products can trigger, this being a reason for fraud to the consumer. By way of example, the presence of a legal substance in doses higher than its recommendation may cause unwanted side effects; on the other hand, its presence in quantities lower than necessary (effective threshold) may not have the effect expected or a...

Instacash: The Ethics of Leveraging Medical Student Status on Social Media
Some medical students leverage their medical student status for profit as social media influencers on platforms such as Instagram. Depending on the size of their following and the brand they are promoting, students can make thousands of dollars per year by advertising products ranging from scrubs to protein powder to mattresses. Yet, they receive few tools as part of their education to help them understand how to reconcile their professional obligations with a desire to generate an income. After examining the potential benefits and harms of social media use, this article considers the possibility of medical student financi...

Powder suspensions in non-aqueous vehicles for delivery of therapeutic proteins.
Abstract
Formulating biopharmaceuticals is a challenging task due to their complex and sensitive nature. Protein drugs are typically marketed either as an aqueous solution or as a lyophilizate. Usually aqueous solutions are preferred as neither drying nor reconstitution are required. But it may be unfeasible if the protein features low stability. An interesting alternative to avoid at least reconstitution are protein powder suspensions in non-aqueous vehicles. Such formulations combine the ready-to-use approach with the high protein stability in the solid state. Additionally, protein powder suspensions off...

Molecules, Vol. 25, Pages 2522: Detecting Low Concentrations of Nitrogen-Based Adulterants in Whey Protein Powder Using Benchtop and Handheld NIR Spectrometers and the Feasibility of Scanning through Plastic Bag
This study developed robust models using benchtop and handheld spectrometers to predict low concentrations of urea, glycine, taurine, and melamine in whey protein powder (WPP). Effectiveness of scanning samples through optical glass and polyethylene bags was also tested for the handheld NIRS. WPP was adulterated up to six concentration levels from 0.5% to 3% w/w. The two spectrometers were used to obtain three datasets of 819 diffuse reflectance spectra each that were pretreated before linear discriminant analysis (LDA) and regression (PLSR). Pretreatment was effective and revealed important absorption bands that could be ...
