RESUMEN

BACKGROUND: Bovine colostrum with egg powder (BC/egg) is rich in essential amino acids and immunoactive compounds. OBJECTIVES: This trial tested the hypothesis that a daily supplement of BC/egg would reduce linear growth faltering and environmental enteric dysfunction (EED) in Malawian infants when compared with an isoenergetic ration of corn/soy flour used as a control. EED was defined by a lactulose permeability test. METHODS: This was a prospective, randomized, blinded, placebo-controlled clinical trial in which 9-mo-old infants received BC/egg or a control for 3 mo. The primary outcomes were change in length-for-age z-score (ΔLAZ) and urinary lactulose excretion (%L) at 12-mo-old. Secondary outcomes included episodes of diarrhea, stunting, EED, and the 16S configuration of the fecal microbiota. RESULTS: Of the 277 children enrolled, 267 completed the intervention phase of the study. LAZ decreased in all children from 9 to 17 mo, although ΔLAZ was less in children receiving BC/egg from 9 to 12 mo (difference = 0.12 z-scores; P = 0.0011). This difference persisted after feeding was completed, with less ΔLAZ (difference = 0.09 z-scores). A lower prevalence of stunting was seen in the intervention group (n = 47/137) than the control group (n = 62/127) at 17 mo (RR = 0.70; 95% CI: 0.52, 0.94).The median %L at 12 mo of age in the children receiving BC/egg was 0.14%, compared with 0.17% in the control group (P = 0.74). In children with %L >0.45% at enrollment (severe EED), the BC/egg group had more children with normal %L at 12 mo of age (10/20, 50%) than was seen in controls (2/15, 13%; P = 0.024). Episodes of diarrhea and ß-diversity of the 16S configuration of fecal microbiota did not differ between the 2 groups. CONCLUSIONS: Addition of BC/egg to complementary feeding in Malawian infants resulted in less linear growth faltering. This trial was registered at clinicaltrials.gov as NCT03801317.

RESUMEN

BACKGROUND: Interest in marijuana edibles has increased as perceptions of harm from marijuana have decreased. Media and peer influences impact youth substance use, and YouTube is the most popular video-sharing website. No studies have examined the content and accessibility of YouTube videos related to marijuana edibles. OBJECTIVES: To describe the messages conveyed to viewers in YouTube videos about edibles and determine their accessibility to youth. METHODS: On June 12, 2015, we searched YouTube for videos about marijuana/cannabis/weed edibles. A total of 51 videos were coded for presence of an age restriction, purpose(s) of the videos, consumption of edibles during the video, effects, and safety concerns. RESULTS: Total views across all 51 videos were >9 million. Only 14% (7/51) were restricted to viewers over the age of 18 years. Over half (27/51, 53%) were informative videos, most (20/27, 74%) teaching how to make edibles, and 37% (19/51) were entertaining videos. Someone consumed an edible in 31% (16/51) of the videos, and the type of high was mentioned in 51% (26/51) of the videos, including delayed (18/26, 69%) or intense high (13/26, 50%). Fifty-five percent (28/51) mentioned delta-9-tetrahydrocannabinol potency or dosage. Only 10 of these (36%) presented this information specifically as a warning to prevent adverse effects. Conclusions/Importance: Edibles-related videos are easily found on YouTube, often instructing how to bake your own edibles and lacking information needed for safe consumption, and most are not age-restricted. Videos showing how to make edibles or presenting edibles use in an entertaining way that could influence youth to initiate use.

RESUMEN

With an increase in the legalization of recreational marijuana across the USA, advertising for marijuana products is more widespread, especially on the Internet where such practices pose a regulatory challenge. In this study, we examined the content of marijuana advertising on Weedmaps, a popular website that markets marijuana retailers online. A total of 146 recreational marijuana retailers in Colorado and Washington were examined on Weedmaps. We studied the age verification practices made in retailers' own websites, the presence of health claims they made about marijuana on Weedmaps, and the characteristics of followers of Weedmaps on social media sites. Many retailers had no security measure to determine age (41 % in Colorado, 35 % in Washington). Approximately 61 % of retailers in Colorado and 44 % in Washington made health claims about the benefits of marijuana, including anxiety reduction, treatment of depression, insomnia, and pain/inflammation. Inferred demographic characteristics of followers of Weedmaps on Twitter and Instagram revealed that over 60 % were male and nearly 70 % or more were age 20-29 years old, yet some (15-18 %) were under the age of 20. Our findings indicate that marijuana retailers have a visible presence on the Internet. Potential customers might be enticed by retailers who tout health claims about marijuana use. It may also be appealing for a younger demographic to overlook age restrictions and engage with marijuana retailers via social media. As a whole, our findings can help to guide future policy making on the issue of marijuana-related advertising.
