There are limited data available about the prevalence of human milk (HM) sharing and selling in the general population. We aimed to describe attitudes toward HM selling among participants in a qualitative-interview study and prevalence of HM sharing and selling among a national sample of U.S. mothers. Mothers (n = 41) in our qualitative-interview study felt that sharing or donating HM was more common than selling; none had ever purchased or sold HM. Three themes related to HM selling emerged from this work: questioning the motives of those selling HM, HM selling limits access to HM to those with money, and HM selling is a legitimate way to make money. Some mothers had reservations about treating HM as a commodity and the intentions of those who profit from the sale of HM. Nearly all participants in our national survey of U.S. mothers (94%, n = 429) had heard of infants consuming another mother's HM. Approximately 12% had provided their milk to another; half provided it to someone they knew. Fewer mothers (6.8%) reported that their infant had consumed another mother's HM; most received this HM from someone they knew. A smaller proportion of respondents (1.3%) had ever purchased or sold HM. Among a national sample of U.S. mothers, purchasing and selling HM was less common than freely sharing HM. Together, these data highlight that HM sharing is not uncommon in the United States. Research is required to create guidelines for families considering HM sharing.

Creatine monohydrate supplementation (CrM) is a safe and effective intervention for improving certain aspects of sport, exercise performance, and health across the lifespan. Despite its evidence-based pedigree, several questions and misconceptions about CrM remain. To initially address some of these concerns, our group published a narrative review in 2021 discussing the scientific evidence as to whether CrM leads to water retention and fat accumulation, is a steroid, causes hair loss, dehydration or muscle cramping, adversely affects renal and liver function, and if CrM is safe and/or effective for children, adolescents, biological females, and older adults.

H5Nx A/Goose/Guangdong/1/96 Eurasian lineage high pathogenicity avian influenza (HPAI) viruses have been the main HPAI strains detected globally since 2005. These have spread around the world, causing a panzootic that has spanned six continents, with continual threat to not only wild and captive birds and poultry, but also wild, captive and domestic mammals and humans. The viruses' ecology and epidemiology - especially the 2.

Optical imaging access to nanometer-level protein distributions in intact tissue is a highly sought-after goal, as it would provide visualization in physiologically relevant contexts. Under the unfavorable signal-to-background conditions of increased absorption and scattering of the excitation and fluorescence light in the complex tissue sample, superresolution fluorescence microscopy methods are severely challenged in attaining precise localization of molecules. We reasoned that the typical use of a confocal detection pinhole in MINFLUX nanoscopy, suppressing background and providing optical sectioning, should facilitate the detection and resolution of single fluorophores even amid scattering and optically challenging tissue environments.

Importance: Safer supply programs were implemented in Canada to provide pharmaceutical-grade alternatives to the toxic unregulated drug supply. While research shows clinical benefits and reduced overdose mortality among safer supply patients, medication diversion remains a concern.
Objective: To examine provider (prescribing clinicians and allied health professionals) and patient perspectives on diversion of opioids prescribed in safer supply programs.

Biosimilars and generics have led to reduced cancer drug prices. The effect of biosimilar or generic drug competition on drug manufacturer revenue has not been previously described. In this study, the majority of top selling cancer drugs had a greater than 50 % decline in sales revenue within 2 years of generic or biosimilar market entry, reflecting both the decline in market share and reduction in unit drug price.
