Median age was 60 years at the time of diagnosis, and 18 of 23 (78.2%) were male. Pathologic analysis of the base-of-tongue specimens showed a primary tumor in only three of 23 (13.0%) of patients. CONCLUSION Despite prior evidence suggesting a high rate of primary site identification in HPV-related disease, robotic base-of-tongue mucosectomy may not be indicated for HPV-negative unknown primary carcinoma based on a low likelihood of finding the primary.

The possibility to use insects for the valorization of by-products from these value chains may represent a sustainable solution. This study aims at investigating the by-products obtained from different food chains for the rearing of black soldier fly prepupae to evaluate lipid content and profile and outline its possible applications. The substrates used in this experiment were (i) industrial by-products (brewery spent grains, cow's milk whey, grape stalks, and tomato peels and seeds) and (ii) by-products from retailers (bread dough, fish scraps, and spent coffee ground). Fat extracted from prepupae using an adjusted Folch method was utilized for total lipid content and fatty acids profile. RESULTS Best larval performances were obtained from beer (0.22 gweight per prepupa), tomato (0.19 gweight per prepupa), and cheese (0.14 gweight per prepupa) food-chain by-products. The extremely different composition of the substrate was reflected in the differentiated lipid profile of black soldier fly prepupae and in a range of ratios between unsaturated and saturated fatty acids comprised from 0.37 for cow's milk way to 1.34 for tomato peels and seeds.
