BACKGROUND:Type 2 diabetes (T2D) contributes to significant morbidity and mortality for Chinese immigrants in the United States, exacerbated by social determinants of health (SDOH) barriers such as language barriers, limited access to healthy foods, and low health literacy. OBJECTIVE:The goal of the Integrating Cultural Aspects into Diabetes Education (INCLUDE) study is to test a social media-based intervention adapting the Diabetes Prevention Program (DPP) for Chinese immigrants alongside a culturally adapted, community-supported agriculture program. Here, we report the protocol for the INCLUDE study. METHODS:INCLUDE is a 3-year randomized controlled trial (n=150). Participants with prediabetes or at risk for T2D are enrolled and randomized into either the control or intervention group (n=75 each). Participants from the intervention group receive 2-3 culturally tailored, in-language DPP videos weekly for 12 weeks, as well as biweekly phone calls from bilingual study staff to review video content, support goal setting, and assess and address SDOH-related barriers such as food insecurity. Intervention participants will also be given produce for 10 weeks as part of the community-supported agriculture program. Weight (primary outcome), self-efficacy, diet, physical activity, and food insecurity (secondary outcomes) are measured at baseline, 3-month, and 6-month intervals. Splined linear mixed models will be used to examine group differences in longitudinal weight and other secondary outcomes. The INCLUDE study was approved by the Institutional Review Board at the NYU Grossman School of Medicine. RESULTS:Recruitment started in May 2023, with the first cohort of 75 participants enrolled and randomized into 2 groups in July 2023. The 3-month and 6-month assessment of the first-year cohort has been completed. We have recruited 75 participants for the second cohort as of July 2024. CONCLUSIONS:The INCLUDE study will serve as an innovative model for culturally adapted, multilevel interventions for underserved communities previously unable to access evidence-based diabetes prevention initiatives. Aligning with several national calls for multilevel interventions, the INCLUDE intervention will provide critical data that will inform how researchers and public health professionals address SDOH barriers faced by underserved populations and prevent diabetes.

PURPOSE/UNASSIGNED:Greater disease burden is a well-established predictor of poorer outcomes following chimeric antigen receptor T-cell (CAR T) therapy. Although bridging therapy (BT) is widely used between leukapheresis and CAR T infusion, limited data have evaluated the impact of BT on CAR T outcomes. In this study, we hypothesized that the quantitative dynamics of radiomic cytoreduction during bridging are prognostic. EXPERIMENTAL DESIGN/UNASSIGNED:Patients with large B-cell lymphoma treated with CD19-CAR T from 2016 to 2022 were included in the study. Metabolic tumor volume (MTV) was determined for all patients on pre-leukapheresis PET and on post-BT/pre-infusion PET in those who received BT. Patients were stratified into "High" and "Low" disease burden using an MTV cutpoint of 65.4cc established by maximally selected log-rank statistic for progression-free survival (PFS). RESULTS/UNASSIGNED:Of 191 patients treated with CAR T, 144 (75%) received BT. In the BT cohort, 56% had a reduction in MTV post-BT. On multivariate analysis, the MTV trajectory across the bridging period remained significantly associated with PFS (P < 0.001); however, notably, patients with improved MTV (High->Low) had equivalent PFS compared with those with initially and persistently low MTV (Low->Low; HR for High->Low MTV: 2.74; 95% confidence interval, 0.82-9.18). There was a reduction in any grade immune effector cell-associated neurotoxicity syndrome in the High->Low MTV cohort as compared with the High->High MTV cohort (13% vs. 41%; P = 0.05). CONCLUSIONS/UNASSIGNED:This is the first study to use radiomics to quantify disease burden pre- and post-BT in a large real-world large B-cell lymphoma cohort. We demonstrate that effective BT can enable initially high-disease burden patients to achieve post-CAR T outcomes comparable with low-disease burden patients.

Highly effective antiobesity and diabetes medications such as glucagon-like peptide 1 (GLP-1) agonists and glucose-dependent insulinotropic polypeptide/GLP-1 (dual) receptor agonists (RAs) have ushered in a new era of treatment of these highly prevalent, morbid conditions that have increased across the globe. However, the rapidly escalating use of GLP-1/dual RA medications is poised to overwhelm an already overburdened health care provider workforce and health care delivery system, stifling its potentially dramatic benefits. Relying on existing systems and resources to address the oncoming rise in GLP-1/dual RA use will be insufficient. Generative artificial intelligence (GenAI) has the potential to offset the clinical and administrative demands associated with the management of patients on these medication types. Early adoption of GenAI to facilitate the management of these GLP-1/dual RAs has the potential to improve health outcomes while decreasing its concomitant workload. Research and development efforts are urgently needed to develop GenAI obesity medication management tools, as well as to ensure their accessibility and use by encouraging their integration into health care delivery systems.

BACKGROUND:Anabolic androgenic steroids (AAS) are synthetic forms of testosterone frequently used as performance enhancing drugs among gay, bisexual, and queer (GBQ) men. Despite widespread use, associated harms, and the likely existence of an AAS use disorder, there is no medical consensus on standards of care for people who use AAS, with most medical providers focusing exclusively on abstinence. Individuals using AAS have developed community-based harm reduction strategies to mitigate these harms. METHODS:This paper is a sub-analysis of qualitative data obtained through semi-structured interviews with GBQ men using AAS for 8 or more weeks recruited through convenience and snowball sampling from clinical sites and LGBTQ + venues in New York City as well as through social media. Interviews were coded with themes developed using reflexive thematic analysis. Data related to harm reduction techniques were then re-analyzed through a prevention strategies framework lens of primary, secondary, and tertiary harm prevention. RESULTS:Thematic saturation was reached at twelve interviews in the primary analysis, with men reporting frequent use of multiple harm reduction techniques. For primary prevention, men avoided oral steroids and simultaneous substance use, tried to obtain AAS from reputable sources, used "cycling" to dose steroids, and practiced sterile injection techniques. Secondary prevention methods included patient-directed lab testing for hematocrit, liver and kidney function, cholesterol, prostate specific antigen, testosterone, and self-performed blood pressure checks. Tertiary prevention included donating blood and the use of medications without a prescription, including aromatase inhibitors, selective estrogen receptor blockers, aspirin, statins, angiotensin receptor blockers, clomiphene, and human chorionic gonadotropin. CONCLUSIONS:Despite many GBQ men experiencing harms from anabolic androgenic steroids, community members have often sought harm reduction techniques in lieu of abstinence. Though many of these techniques embrace clinical reasoning and may be more broadly applicable, additional research is needed to understand the impact of each intervention on the overall health of individuals using AAS.

Medical ethics education is crucial for medical students and trainees, helping to shape attitudes, beliefs, values, and professional identities. Exploration of ethical dilemmas and approaches to resolving them provides a broader understanding of the social and cultural contexts in which medicine is practiced, as well as the ethical implications of medical decisions, fostering critical thinking and self-reflection skills imperative to providing patient-centered care. However, exposure to medical ethics topics and their clinical applications can be limited by curricular constraints and the availability of institutional resources and expertise. Podcasts, among other Free Open Access Medical Education (FOAMed) resources, are a novel educational tool that offers particular advantages for self-directed learning, a process by which learners engage in asynchronous educational opportunities outside of traditional academic or clinical settings. Podcasts can be readily distributed to wide audiences and played at any time, reducing barriers to access and offering a level of flexibility that is not possible with traditional forms of education and is well-suited to busy schedules. Podcasts can also use real voices and storytelling to make the content memorable and eminently human. This paper describes the development, production process, and impact of Core IM's "At the Bedside," a podcast focusing on issues in medical ethics and the medical humanities, intending to supplement standard bioethics curricula in an accessible, relevant, and engaging way. The authors advocate for broad incorporation of podcasts into medical ethics education.

BACKGROUND:Weight stigma is a fundamental cause of health inequality. Body positivity may be a counterbalance to weight stigma. Social media is replete with weight-stigmatizing content and is a driver of poor mental health outcomes; however, there remains a gap in understanding its potential to mitigate the prevalence and impact of harmful messaging and to promote positive effects on a large scale. OBJECTIVE:We selected musical artist Lizzo, whose brand emphasizes body positivity and empowerment, for an instrumental case study on the discourse on social media and specifically Instagram. We focused on 3 domains, including body positivity, physical health, and emotional well-being. These domains challenge social norms around weight and body size and have the potential to positively affect the physical and psychological health of people with diverse body sizes. METHODS:We evaluated posts by Lizzo, comments from Instagram users, and replies to comments over a 2-month period (October 11 to December 12, 2019). Two coders rated Lizzo's posts and Instagram users' comments for their sentiments on the 3 domains. Replies to Instagram users' comments were assessed for their reactions to comments (ie, did they oppose or argue against the comment or did they support or bolster the comment). Engagement metrics, including the number of "likes," were also collected. RESULTS:The final sample included 50 original posts by Lizzo, 250 comments from Instagram users, and 1099 replies to comments. A proportion of Lizzo's content included body positive sentiments (34%) and emotional well-being (18%); no posts dealt explicitly with physical health. A substantial amount Instagram users' comments and replies contained stigmatizing content including the use of nauseated and vomiting emojis, implications that Lizzo's body was shameful and should be hidden away, accusations that she was promoting obesity, and impeachments of Lizzo's health. In spite of the stigmatizing content, we also discovered content highlighting the beneficial nature of having positive representation of a Black woman living in a larger body who is thriving. Moreover, analysis of the discourse between users illustrated that stigmatizing expressions are being combated online, at least to some degree. CONCLUSIONS:This study demonstrates that Lizzo has exposed millions of social media users to messages about body positivity and provided more visibility for conversations about weight and shape. Future research should examine the extent to which body positive messages can lead to greater acceptance of individuals living in larger bodies. Instagram and other social media platforms should consider ways to reduce body-shaming content while finding ways to promote content that features diverse bodies. Shifting the landscape of social media could decrease stereotypes about weight and shape while increasing dialog about the need for greater acceptance and inclusion of people with diverse bodies.

Although St-Jules et al have presented the case for postprandial hyperkalemia with food, including plant foods, there (still) is little to no direct evidence supporting the occurrence of postprandial hyperkalemia, mostly due to a lack of studies performed exclusively using food. Food is different than salts or supplements, and it is likely that a banana behaves differently than potassium salts. A growing body of evidence supports the use of plant foods without causing hyperkalemia in patients with kidney disease. Currently, only 1 study has reported on the postprandial effects of hyperkalemia. In this study, there was a substantial reduction in the instances of postprandial hyperkalemia in participants consuming a diet that included more plant foods and more fiber. At the time of this writing, there is no evidence to support risk or safety of certain foods with regard to postprandial hyperkalemia, and additional research is warranted.
