Relapsing White Matter Disease and Subclinical Optic Neuropathy: From the National Multiple Sclerosis Society Case Conference Proceedings

O'Neill, Kimberly A; Dugue, Andrew; Abreu, Nicolas J; Balcer, Laura J; Branche, Marc; Galetta, Steven; Graves, Jennifer; Kister, Ilya; Magro, Cynthia; Miller, Claire; Newsome, Scott D; Pappas, John; Rucker, Janet; Steigerwald, Connolly; William, Christopher M; Zamvil, Scott S; Grossman, Scott N; Krupp, Lauren B
A 16-year-old adolescent boy presented with recurrent episodes of weakness and numbness. Brain MRI demonstrated subcortical, juxtacortical, and periventricular white matter T2 hyperintensities with gadolinium enhancement. CSF was positive for oligoclonal bands that were not present in serum. Despite treatment with steroids, IV immunoglobulins, plasmapheresis, and rituximab, he continued to have episodes of weakness and numbness and new areas of T2 hyperintensity on imaging. Neuro-ophthalmologic examination revealed a subclinical optic neuropathy with predominant involvement of the papillomacular bundle. Genetic evaluation and brain biopsy led to an unexpected diagnosis.

Evaluation of novel candidate filtration markers from a global metabolomic discovery for glomerular filtration rate estimation

Fino, Nora; Adingwupu, Ogechi M; Coresh, Josef; Greene, Tom; Haaland, Ben; Shlipak, Michael G; Costa E Silva, Veronica T; Kalil, Roberto; Mindikoglu, Ayse L; Furth, Susan L; Seegmiller, Jesse C; Levey, Andrew S; Inker, Lesley A
Creatinine and cystatin-C are recommended for estimating glomerular filtration rate (eGFR) but accuracy is suboptimal. Here, using untargeted metabolomics data, we sought to identify candidate filtration markers for a new targeted assay using a novel approach based on their maximal joint association with measured GFR (mGFR) and with flexibility to consider their biological properties. We analyzed metabolites measured in seven diverse studies encompasing 2,851 participants on the Metabolon H4 platform that had Pearson correlations with log mGFR and used a stepwise approach to develop models to < -0.5 estimate mGFR with and without inclusion of creatinine that enabled selection of candidate markers. In total, 456 identified metabolites were present in all studies, and 36 had correlations with mGFR < -0.5. A total of 2,225 models were developed that included these metabolites; all with lower root mean square errors and smaller coefficients for demographic variables compared to estimates using untargeted creatinine. Seventeen metabolites were chosen, including 12 new candidate filtration markers. The selected metabolites had strong associations with mGFR and little dependence on demographic factors. Candidate metabolites were identified with maximal joint association with mGFR and minimal dependence on demographic variables across many varied clinical settings. These metabolites are excreted in urine and represent diverse metabolic pathways and tubular handling. Thus, our data can be used to select metabolites for a multi-analyte eGFR determination assay using mass spectrometry that potentially offers better accuracy and is less prone to non-GFR determinants than the current eGFR biomarkers.

Loeb, Stacy; Sanchez Nolasco, Tatiana; Byrne, Nataliya; Allen, Laura; Langford, Aisha T; Ravenell, Joseph; Gomez, Scarlett Lin; Washington, Samuel L; Borno, Hala T; Griffith, Derek M; Criner, Nickole
PURPOSE/UNASSIGNED:Although the majority of US adults obtain health information on the internet, the quality of information about prostate cancer is highly variable. Black adults are underrepresented in online content about prostate cancer despite a higher incidence of and mortality from the disease. The goal of this study was to explore the perspectives of Black patients with prostate cancer on the importance of racial representation in online content and other factors influencing trust. MATERIALS AND METHODS/UNASSIGNED:We conducted 7 virtual focus groups with Black patients with prostate cancer in 2022 and 2023. Participants completed an intake questionnaire with demographics followed by a group discussion, including feedback on purposefully selected online content. Transcripts were independently analyzed by 2 investigators experienced in qualitative research using a constant comparative method. RESULTS/UNASSIGNED:Most participants use online sources to look for prostate cancer information. Racial representation is an important factor affecting trust in the content. A lack of Black representation has consequences, including misperceptions about a lower risk of prostate cancer and discouraging further information-seeking. Other key themes affecting trust in online content included the importance of a reputable source of information, professional website structure, and soliciting money. CONCLUSIONS/UNASSIGNED:Underrepresentation of Black adults in prostate cancer content has the potential to worsen health disparities. Optimal online communications should include racially diverse representation and evidence-based information in a professional format from reputable sources without financial conflict.

Prostate cancer and podcasts: an analysis and assessment of the quality of information about prostate cancer available on podcasts

Scott, Colin; Campbell, Peter; Nemirovsky, Amy; Loeb, Stacy; Malik, Rena
Podcasts represent a new source of information for patients and families dealing with prostate cancer, but no studies have been conducted evaluating the quality of information in them. Evaluating for: (1) quality based on the validated DISCERN criteria, (2) understandability and actionability based on the Patient Education Materials Assessment Tool (PEMAT), (3) misinformation, and (4) commercial bias, we concluded that podcasts are currently not good sources of information for lay health consumers.

Cognitive impairment and outcomes in older adults with non-ST-elevation acute coronary syndrome

Dirjayanto, Valerie Josephine; Alkhalil, Mohammad; Dodson, John; Mills, Gregory; Pompei, Graziella; Rubino, Francesca; Kunadian, Vijay
OBJECTIVE:This study aimed to explore the prognostic impact of cognitive impairment on the long-term risk of major adverse cardiovascular events (MACEs) in older patients with non-ST-elevation acute coronary syndrome (NSTEACS) undergoing invasive treatment. METHODS:Patients aged ≥75 years with NSTEACS undergoing an invasive strategy were included in the multicentre prospective study (NCT01933581). Montreal Cognitive Assessment was used to evaluate cognitive status at baseline (scores ≥26 classified as normal, <26 as cognitive impairment). Long-term follow-up data were obtained from electronic patient care records. The primary endpoint was MACE as a composite of all-cause deaths, reinfarction, stroke/transient ischaemic attack, urgent revascularisation and significant bleeding. RESULTS:239 patients with baseline cognitive assessment completed long-term follow-up. Median age was 80.9 years (IQR 78.2-83.9 years) and 62.3% were male. On 5-year follow-up, there was no significant difference in the occurrence of MACE between the cognitively impaired group and the normal cognition group (p=0.155). Cognition status was not associated with MACE (HR 1.37 (95% CI 0.96 to 1.95); p=0.082). However, there was significantly more deaths (p=0.005) in those with cognitive impairment. Kaplan-Meier survival analysis (log-rank p=0.003) and Cox regression analysis (aHR 1.85 (95% CI 1.11 to 3.08); p=0.018) revealed increased risk of all-cause mortality, even after adjusting for frailty and GRACE (Global Registry of Acute Coronary Events) score. CONCLUSION/CONCLUSIONS:Cognitive impairment in older patients with NSTEACS undergoing an invasive strategy was associated with long-term all-cause mortality. Routine cognitive screening may aid risk stratification and further studies are needed to identify how this should influence management strategies and individual decision-making in this patient group.

Factors Associated with Patient Adherence to Biofeedback Therapy Referral for Migraine: An Observational Study

Minen, Mia T; George, Alexis; Cuneo, Ami Z
Biofeedback has Grade A evidence for the treatment of migraine, yet few studies have examined the factors associated with patients' decisions to pursue biofeedback treatment recommendations. We sought to examine reasons for adherence or non-adherence to referral to biofeedback therapy as treatment for migraine. Patients with migraine who had been referred for biofeedback by a headache specialist/behavioral neurologist were interviewed in person or via Webex. Patients completed an enrollment questionnaire addressing demographics and questions related to their headache histories. At one month, patients were sent a follow-up questionnaire via REDCap and asked if they had pursued the recommendation for biofeedback therapy, their reasons for their decision, and their impressions about biofeedback for those who pursued it. Nearly two-thirds (65%; 33/51) of patients responded at one month. Of these, fewer than half (45%, 15/33) had contacted biofeedback providers, and only 18% (6/33) completed a biofeedback session. Common themes emerged for patients who did not pursue biofeedback, including feeling that they did not have time, concern for financial obstacles (e.g., treatment cost and/or insurance coverage), and having difficulty scheduling an appointment due to limited provider availability. When asked about their preference between type of biofeedback provider (e.g., a physical therapist or psychologist), qualitative responses were mixed; many patients indicated no preference as long as they took insurance and/or were experienced, while others indicated a specific preference for a physical therapist or psychologist due to familiarity, or prior experiences with that kind of provider. Patients with migraine referred for biofeedback therapy face numerous obstacles to pursuing treatment.

Serious illness communication skills training for emergency physicians and advanced practice providers: a multi-method assessment of the reach and effectiveness of the intervention

Adeyemi, Oluwaseun; Ginsburg, Alexander D; Kaur, Regina; Cuthel, Allison M; Zhao, Nicole; Siman, Nina; Goldfeld, Keith S; Emlet, Lillian Liang; DiMaggio, Charles; Yamarik, Rebecca Liddicoat; Bouillon-Minois, Jean-Baptiste; Chodosh, Joshua; Grudzen, Corita R; ,
BACKGROUND:EM Talk is a communication skills training program designed to improve emergency providers' serious illness conversational skills. Using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework, this study aims to assess the reach of EM Talk and its effectiveness. METHODS:EM Talk consisted of one 4-h training session during which professional actors used role-plays and active learning to train providers to deliver serious/bad news, express empathy, explore patients' goals, and formulate care plans. After the training, emergency providers filled out an optional post-intervention survey, which included course reflections. Using a multi-method analytical approach, we analyzed the reach of the intervention quantitatively and the effectiveness of the intervention qualitatively using conceptual content analysis of open-ended responses. RESULTS:A total of 879 out of 1,029 (85%) EM providers across 33 emergency departments completed the EM Talk training, with the training rate ranging from 63 to 100%. From the 326 reflections, we identified meaning units across the thematic domains of improved knowledge, attitude, and practice. The main subthemes across the three domains were the acquisition of Serious Illness (SI) communication skills, improved attitude toward engaging qualifying patients in SI conversations, and commitment to using these learned skills in clinical practice. CONCLUSION/CONCLUSIONS:Our study showed the extensive reach and the effectiveness of the EM Talk training in improving SI conversation. EM Talk, therefore, can potentially improve emergency providers' knowledge, attitude, and practice of SI communication skills. TRIAL REGISTRATION/ NCT03424109; Registered on January 30, 2018.

Association of Socioeconomic Status With Life's Essential 8 in the National Health and Nutrition Examination Survey: Effect Modification by Sex

Williams, Amaris; Nolan, Timiya S; Luthy, Jacsen; Brewer, LaPrincess C; Ortiz, Robin; Venkatesh, Kartik K; Sanchez, Eduardo; Brock, Guy N; Nawaz, Saira; Garner, Jennifer A; Walker, Daniel M; Gray, Darrell M; Joseph, Joshua J
BACKGROUND:Higher scores for the American Heart Association Life's Essential 8 (LE8) metrics, blood pressure, cholesterol, glucose, body mass index, physical activity, smoking, sleep, and diet, are associated with lower risk of chronic disease. Socioeconomic status (SES; employment, insurance, education, and income) is associated with LE8 scores, but there is limited understanding of potential differences by sex. This analysis quantifies the association of SES with LE8 for each sex, within Hispanic Americans, non-Hispanic Asian Americans, non-Hispanic Black Americans, and non-Hispanic White Americans. METHODS AND RESULTS/RESULTS:for all interactions <0.05). Among non-Hispanic Asian Americans and Hispanic Americans, the association of SES with LE8 was not different between men and women, and women had greater LE8 scores than men at all SES levels (eg, high school or less, some college, and college degree or more). CONCLUSIONS:The factors that explain the sex differences among non-Hispanic Black Americans and non-Hispanic White Americans, but not non-Hispanic Asian Americans and Hispanic Americans, are critical areas for further research to advance cardiovascular health equity.

Li, Yiting; Menon, Gayathri; Kim, Byoungjun; Bae, Sunjae; Quint, Evelien E; Clark-Cutaia, Maya N; Wu, Wenbo; Thompson, Valerie L; Crews, Deidra C; Purnell, Tanjala S; Thorpe, Roland J; Szanton, Sarah L; Segev, Dorry L; McAdams DeMarco, Mara A
IMPORTANCE/UNASSIGNED:Identifying the mechanisms of structural racism, such as racial and ethnic segregation, is a crucial first step in addressing the persistent disparities in access to live donor kidney transplantation (LDKT). OBJECTIVE/UNASSIGNED:To assess whether segregation at the candidate's residential neighborhood and transplant center neighborhood is associated with access to LDKT. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:In this cohort study spanning January 1995 to December 2021, participants included non-Hispanic Black or White adult candidates for first-time LDKT reported in the US national transplant registry. The median (IQR) follow-up time for each participant was 1.9 (0.6-3.0) years. MAIN OUTCOME AND MEASURES/UNASSIGNED:Segregation, measured using the Theil H method to calculate segregation tertiles in zip code tabulation areas based on the American Community Survey 5-year estimates, reflects the heterogeneity in neighborhood racial and ethnic composition. To quantify the likelihood of LDKT by neighborhood segregation, cause-specific hazard models were adjusted for individual-level and neighborhood-level factors and included an interaction between segregation tertiles and race. RESULTS/UNASSIGNED:Among 162 587 candidates for kidney transplant, the mean (SD) age was 51.6 (13.2) years, 65 141 (40.1%) were female, 80 023 (49.2%) were Black, and 82 564 (50.8%) were White. Among Black candidates, living in a high-segregation neighborhood was associated with 10% (adjusted hazard ratio [AHR], 0.90 [95% CI, 0.84-0.97]) lower access to LDKT relative to residence in low-segregation neighborhoods; no such association was observed among White candidates (P for interaction = .01). Both Black candidates (AHR, 0.94 [95% CI, 0.89-1.00]) and White candidates (AHR, 0.92 [95% CI, 0.88-0.97]) listed at transplant centers in high-segregation neighborhoods had lower access to LDKT relative to their counterparts listed at centers in low-segregation neighborhoods (P for interaction = .64). Within high-segregation transplant center neighborhoods, candidates listed at predominantly minority neighborhoods had 17% lower access to LDKT relative to candidates listed at predominantly White neighborhoods (AHR, 0.83 [95% CI, 0.75-0.92]). Black candidates residing in or listed at transplant centers in predominantly minority neighborhoods had significantly lower likelihood of LDKT relative to White candidates residing in or listed at transplant centers located in predominantly White neighborhoods (65% and 64%, respectively). CONCLUSIONS/UNASSIGNED:Segregated residential and transplant center neighborhoods likely serve as a mechanism of structural racism, contributing to persistent racial disparities in access to LDKT. To promote equitable access, studies should assess targeted interventions (eg, community outreach clinics) to improve support for potential candidates and donors and ultimately mitigate the effects of segregation.
