Background There is a need for reliable noninvasive methods for diagnosing and monitoring nonalcoholic fatty liver disease (NAFLD). Thus, the multidisciplinary Non-invasive Biomarkers of Metabolic Liver disease (NIMBLE) consortium was formed to identify and advance the regulatory qualification of NAFLD imaging biomarkers. Purpose To determine the different-day same-scanner repeatability coefficient of liver MRI biomarkers in patients with NAFLD at risk for steatohepatitis. Materials and Methods NIMBLE 1.2 is a prospective, observational, single-center short-term cross-sectional study (October 2021 to June 2022) in adults with NAFLD across a spectrum of low, intermediate, and high likelihood of advanced fibrosis as determined according to the fibrosis based on four factors (FIB-4) index. Participants underwent up to seven MRI examinations across two visits less than or equal to 7 days apart. Standardized imaging protocols were implemented with six MRI scanners from three vendors at both 1.5 T and 3 T, with central analysis of the data performed by an independent reading center (University of California, San Diego). Trained analysts, who were blinded to clinical data, measured the MRI proton density fat fraction (PDFF), liver stiffness at MR elastography (MRE), and visceral adipose tissue (VAT) for each participant. Point estimates and CIs were calculated using χ2 distribution and statistical modeling for pooled repeatability measures. Results A total of 17 participants (mean age, 58 years ± 8.5 [SD]; 10 female) were included, of which seven (41.2%), six (35.3%), and four (23.5%) participants had a low, intermediate, or high likelihood of advanced fibrosis, respectively. The different-day same-scanner mean measurements were 13%-14% for PDFF, 6.6 L for VAT, and 3.15 kPa for two-dimensional MRE stiffness. The different-day same-scanner repeatability coefficients were 0.22 L (95% CI: 0.17, 0.29) for VAT, 0.75 kPa (95% CI: 0.6, 0.99) for MRE stiffness, 1.19% (95% CI: 0.96, 1.61) for MRI PDFF using magnitude reconstruction, 1.56% (95% CI: 1.26, 2.07) for MRI PDFF using complex reconstruction, and 19.7% (95% CI: 15.8, 26.2) for three-dimensional MRE shear modulus. Conclusion This preliminary study suggests that thresholds of 1.2%-1.6%, 0.22 L, and 0.75 kPa for MRI PDFF, VAT, and MRE, respectively, should be used to discern measurement error from real change in patients with NAFLD.

Uptake of preexposure prophylaxis (PrEP) has been slow, but is increasing. Although PrEP is indicated for many patients, it has been concentrated among men who have sex with men (MSM). Awareness of PrEP is limited among non-MSM individuals, and among some MSM. As such, individuals at risk for HIV who are unaware of PrEP must rely on their medical providers to initiate conversations about PrEP. Members of a national professional organization of HIV specialists with prescribing privileges, including physicians, nurse practitioners, and physician assistants, participated in an online survey (n = 342) to characterize their PrEP prescribing behaviors and the demographic membership of their PrEP patients. Results indicated that when discussing PrEP with their patients, providers who more frequently initiated these conversations had a higher percentage of non-MSM patients in their PrEP caseload (e.g., women, people who inject drugs, transgender patients). Encouraging providers to initiate discussions about PrEP with their patients and helping them locate support to offset the cost may help increase uptake, particularly among at-risk patients who are underrepresented in PrEP adoption.

This article examines Washed Ashore: Art to Save the Sea, a project developed by the Artula Institute for Arts and Environmental Education of Bandon, Oregon. Using art to shed light on issues related to trash found in the ocean environment, the Washed Ashore project brings increased awareness to this growing crisis and the resulting beach litter through a traveling exhibit that features massive, awe-inspiring sculptures constructed of only recovered, recycled trash from the sea. Like many artists, such as Andy Goldsworthy, Alan Sonfist, Marina DeBris, and Aviva Rahmani, the Washed Ashore team creates an eco-art series that "inspires caring and respect for the world in which we live, stimulates dialogue, sparks imagination and contributes to the socio-cultural transformations whereby the diversity of life forms found on earth may flourish" (Wallen, 2012, p. 235). Their pieces offer elementary and middle school students a meaningful and concrete example of an integrative STEAM (science, technology, engineering, art, and math) lesson on how art can help renew the ocean ecosystem worldwide.

The article explores Afro-Asian histories through intersectional theory and art practice. It identifies tensions and solidarities in African American and Asian American history and explains the proposed tenets of intersectionality including interdependent social labels, intersecting power relations that produce social inequalities and shape individual experiences and perspectives, and solving of social problems. The implications of forming racial allyship for art education is discussed.
