BACKGROUND: Kidney transplantation is a complex process requiring extensive preparation and ongoing monitoring. Artificial intelligence (AI)-powered chatbots hold potential for providing accessible health information, but our understanding of their role in offering health advice for kidney transplantation and how individuals assess such advice remains limited. This study investigates how individuals evaluate ChatGPT\'s responses to kidney transplantation questions in terms of information quality and empathy, focusing on potential differences across race/ethnicity and educational backgrounds.
METHODS: We collected Reddit posts (N = 4624) regarding kidney transplantation and selected 86 questions to represent typical clinician inquiries. These questions were used as input prompts for ChatGPT. A total of 565 participants assessed ChatGPT\'s responses through online surveys, rating information quality and empathy using Likert scales.
RESULTS: Multilevel analyses (N = 2825) show that there is a significant interaction between race/ethnicity and education levels in various measures related to perceived information quality, but not perceived empathy of ChatGPT\'s responses: accuracy (p < 0.05); authenticity (p < 0.01); believability (p < 0.05); informativeness (p = 0.053); usefulness (p < 0.05); recognizing users\' feelings (p = 0.70) and understanding feelings and situations (p = 0.65). Among non-White individuals, higher education levels predicted higher perceived quality of ChatGPT\'s responses across all information quality measures. Notably, this trend was reversed for White individuals, where higher education levels led to lower perceived information quality.
CONCLUSIONS: Our results highlight the importance of developing AI tools sensitive to diverse communication styles and information needs.

UNASSIGNED: To assess the effectiveness and safety of bimatoprost sustained release (SR) glaucoma implant as a treatment for open-angle glaucoma and ocular hypertension in a real-world private practice setting with a significant American Indian population.
UNASSIGNED: This retrospective study included 156 eyes from adult patients who received a single injection of bimatoprost implant between June 2020 and May 2022 at the Oklahoma Eye Surgeons. Patients were stratified by baseline intraocular pressure (IOP) (≥21 mmHg versus IOP<21 mmHg). The co-primary endpoints were changes in the mean IOP and the number of topical IOP-lowering medications from baseline to Month 6.
UNASSIGNED: At 6 months, eyes with baseline IOP≥21 mmHg had a significantly lower mean IOP (19.85±8.01 versus 26.25±4.84 mmHg; p<0.0001) and the mean number of IOP-lowering medications (1.04±1.44 versus 1.38±1.50; p=0.048) compared with baseline. One year after implantation, 73.58% of eyes had a ≥20% reduction in IOP, 41.51% were medication-free and 30.19% were receiving at least one fewer medication. Among eyes with baseline IOP<21 mmHg, there was a significant reduction in the mean number of IOP-lowering medicines by Month 6 (0.61±1.03 versus 1.93±1.21 at baseline; p<0.0001), with no change in IOP. At 12 months, 24.27% of eyes had a ≥20% decrease in IOP, 43.69% of eyes did not require any medications and 63.11% had at least one fewer medication compared with baseline. An analysis using Welch\'s two-sample t-test showed no significant differences in the outcomes between the overall population and the American Indian population (number of eyes, 23).
UNASSIGNED: Bimatoprost SR glaucoma implant lowered IOP in eyes with high, uncontrolled baseline IOP, while it reduced the number of medications in eyes with a controlled baseline IOP. No clinically meaningful and statistically significant differences in the efficacy of bimatoprost were observed in patients of American Indian descent.

Chronic musculoskeletal pain is a leading cause of disability worldwide. Previous research indicates ethnic/race groups are disproportionately affected by chronic pain conditions. However, when considering socioenvironmental factors these disparities are no longer observed. Ethnic/race group differences have also been reported in pain-related brain structure. Given that environmental and sociocultural factors influence biology and health outcomes, this study aimed to investigate possible environmental and sociocultural contributions to structural differences in pain-related brain regions. A total of 147 non-Hispanic black and non-Hispanic white, middle and older aged adults with knee pain in the past month and a brain MRI are included in the analyses. Individuals also provided information specific to health and pain history and environmental and sociocultural resources. In hierarchical multiple regression models, sociocultural and environmental factors explained 6%-37% of the variance in thickness of pain-related brain regions, with seven of the eight brain regions being statistically significant. In the amygdala, hippocampus, insula, bilateral primary somatosensory cortex, and thalamus, ethnicity/race provided an additional 4%-13% of explanatory value. In the rostral/caudal anterior cingulate and dorsolateral prefrontal cortex, ethnicity/race was not a predictor after accounting for environmental, sociocultural, and other demographic measures. Findings inform health disparities research by elucidating the complexity of factors contributing to previously reported ethnicity/race group differences.

Systematic assessments of the presence and severity of particular symptoms over time are relatively uncommon for Lyme disease patients in the United States, and especially for Lyme disease patients with extracutaneous manifestations (ECLD).
Symptoms and symptom severity of 12 particular symptoms were evaluated in a prospective study at baseline and at 12 months for 35 adult Lyme disease patients with ECLD, 91.4% of whom were already started on antibiotic therapy, and compared with 52 adult Lyme disease patients with erythema migrans, who were untreated at study entry.
No significant difference in the frequency of having at least 1 symptom of the 12 evaluated was found between the 2 groups at either the baseline visit or the 12-month evaluation. Demographic variables were also similar between the 2 study groups, except that the ECLD patients were significantly less likely to be Caucasian: 24/35 (68.6%) of the ECLD cases vs 48/52 (92.3%) of the erythema migrans cases; P = .008.
Lyme disease patients with ECLD had a similar frequency of symptoms at baseline compared with patients with erythema migrans. ECLD subjects, however, were significantly less likely to be Caucasian, raising the question of whether a preceding erythema migrans skin lesion may have been missed in persons with a darker skin color. An important limitation of our study, however, is that we did not record skin color per se, which should be considered for future studies.

Preemptive wait-listing of deceased donor kidney transplant (DDKT) candidates before maintenance dialysis increases the likelihood of transplantation and improves outcomes among transplant patients. Previous studies have identified substantial disparities in rates of preemptive listing, but a gap exists in examining geographic sources of disparities, particularly for sub-regional units. Identifying small area hot spots where delayed listing is particularly prevalent may more effectively inform both health policy and regionally appropriate interventions.
We conducted a retrospective cohort study utilizing 2010-2020 Scientific Registry of Transplant Recipients (SRTR) data for all DDKT candidates to examine overall and race-stratified geospatial hot spots of post-dialysis wait-listing in U.S. zip code tabulation areas (ZCTA). Three geographic clustering methods were utilized to identify robust statistically significant hot spots of post-dialysis wait-listing.
Novel sub-regional hot spots were identified in the southeast, southwest, Appalachia, and California, with a majority existing in the southeast. Race-stratified results were more nuanced, but broadly reflected similar patterns. Comparing transplant candidates in hot spots to candidates in non-clusters indicated a strong association between residence in hot spots and high area deprivation (OR: 6.76, 95%CI: 6.52-7.02), indicating that improving access healthcare in these areas may be particularly beneficial.
Our study identified overall and race-stratified hot spots with low rates of preemptive wait list placement in the U.S., which may be useful for prospective healthcare policy and interventions via targeting of these narrowly defined geographical areas.

Mucosal melanoma (MM) is a rare melanoma subtype with distinct biology and poor prognosis. Data on the efficacy of immune checkpoint inhibitors (ICIs) are limited. We determined the efficacy of ICIs in MM, analyzed by primary site and ethnicity/race.
A retrospective cohort study from 25 cancer centers in Australia, Europe, USA and Asia was carried out. Patients with histologically confirmed MM were treated with anti-programmed cell death protein 1 (PD-1) ± ipilimumab. Primary endpoints were response rate (RR), progression-free survival (PFS), overall survival (OS) by primary site (naso-oral, urogenital, anorectal, other), ethnicity/race (Caucasian, Asian, Other) and treatment. Univariate and multivariate Cox proportional hazards model analyses were conducted.
In total, 545 patients were included: 331 (63%) Caucasian, 176 (33%) Asian and 20 (4%) Other. Primary sites included 113 (21%) anorectal, 178 (32%) urogenital, 206 (38%) naso-oral and 45 (8%) other. Three hundred and forty-eight (64%) patients received anti-PD-1 and 197 (36%) anti-PD-1/ipilimumab. RR, PFS and OS did not differ by primary site, ethnicity/race or treatment. RR for naso-oral was numerically higher for anti-PD-1/ipilimumab [40%, 95% confidence interval (CI) 29% to 54%] compared with anti-PD-1 (29%, 95% CI 21% to 37%). Thirty-five percent of patients who initially responded progressed. The median duration of response (mDoR) was 26 months (95% CI 18 months-not reached). Factors associated with short PFS were Eastern Cooperative Oncology Group (ECOG) performance status (PS) ≥3 (P < 0.01), lactate dehydrogenase (LDH) more than the upper limit of normal (ULN) (P = 0.01), lung metastases (P < 0.01) and ≥1 previous treatments (P < 0.01). Factors associated with short OS were ECOG PS ≥1 (P < 0.01), LDH >ULN (P = 0.03), lung metastases (P < 0.01) and ≥1 previous treatments (P < 0.01).
MM has poor prognosis. Treatment efficacy of anti-PD-1 ± ipilimumab was similar and did not differ by ethnicity/race. Naso-oral primaries had numerically higher response to anti-PD-1/ipilimumab, without difference in survival. The addition of ipilimumab did not show greater benefit over anti-PD-1 for other primary sites. In responders, mDoR was short and acquired resistance was common. Other factors, including site and number of metastases, were associated with survival.

The elderly population has extensively increased globally, so depression like a common problem in late life may convert to one of the economic, social, and health challenges of the 21st century. Due to the high cost of clinical diagnosis of depression, it is necessary to provide effective questionnaires like the 15-item Geriatric Depression Scale (GDS-15) for screening. But, the measurement invariance of GDS-15 is still unknown in the general population. In our study, 1473 participants of all Iran\'s ethnic groups were asked to answer GDS-15 and demographic factors such as human settlements, employment, disease, marital status, age, gender, homebound, financial status, and ethnicity. Then, the lordif package in R 3.1.3 was used to assess differential item functioning (DIF) items that behave unevenly across demographic factors. Our findings reveal that women, homebound patients, poorer, and non-Persian mother tongue score classic psychological symptoms higher than peoples of the same depression score in other groups. Since, psychologists have to remove or replace these items before using this questionnaire for screening geriatric depression.

Although many children experience trauma, few receive diagnoses and subsequent care despite experiencing trauma-related sequelae. At age nine (M = 9.11), children (N = 62; female = 46.4%) who predominantly identified as Black (78.7%) were enrolled in this first study examining how skin conductance as captured by mobile technology, eSense, related to children\'s traumatic experiences and trauma-related symptoms. Skin conductance measures were associated with degree of trauma exposure and PTSD hyperarousal symptoms. These findings suggest that physiological responses in addition to self-report measures may be easily used to assess children\'s trauma exposure and symptoms. Given eSense\'s ease-of-use, this technology could assist clinics and research institutions assess children\'s trauma-related needs.

BACKGROUND: Delayed time to listing (TTL) for pediatric transplant patients is associated with increased risks of mortality and morbidity. The full range of health disparities, sociodemographic factors, and other barriers associated with delays in listing in the pediatric transplant candidate evaluation process has not been fully examined.
METHODS: Retrospective chart reviews were conducted for 183 kidney, liver, and heart transplant candidates ages 0-18 who were referred for evaluation during 2012-2015. Demographic information and potential barriers (e g., social/medical factors, financial concerns) were gathered from pre-transplant evaluations and included in a comprehensive model to evaluate mechanisms that explain differences in TTL. Descriptive statistics, logistic regression models, Cox proportional hazards models, and path analysis were used for analyses.
RESULTS: Candidates included 26.8% heart, 33.3% liver, and 39.9% kidney patients. The most common barrier to listing was financial (71.6%), followed by caregiver psychological or substance use (57.9%), and medical problems (49.7%). Higher age, kidney, and liver organ type (relative to the heart), and presence of social, medical, administrative/motivation, and financial barriers were all directly associated with longer TTL. Public insurance was indirectly associated with TTL through social, administrative/motivation, and financial barriers. Organ type was indirectly associated with TTL through financial barriers.
CONCLUSIONS: Results suggest social problems, administrative issues, and financial issues act as mechanisms through which insurance type and liver transplant candidates face increased risk of delays in transplant listing time. There are numerous clinical implications and interventions that are warranted to reduce TTL among pediatric transplant candidates with co-occurring barriers.

Ethnicity/race and poverty are among determinants of health in older persons. However, studies involving intersectional effects of ethnicity/race and poverty on health of older adults within multi-ethnic Asian populace is limited. Hence, this study aimed to examine the intersectional effects of ethnicity/race and poverty on cognitive function, depressive symptoms, and multimorbidity among community-dwelling older adults in Malaysia.
Data were obtained from the first wave of a Peninsular Malaysia national survey - \"Identifying Psychosocial and Identifying Economic Risk Factor of Cognitive Impairment among Elderly\". Log-binomial regression was used to identify intersectional effects and associations between control variables and health outcomes. A comparison between Malay and non-Malay older adults within the same poverty group, as well as hardcore poor and non-hardcore poor older people within the same ethnicity groups, were conducted to understand the intersectional effects of ethnicity/race and poverty on health.
Prevalence of cognitive impairment was highest among hardcore poor Malay group, while the risk of depression and multimorbidity were highest among hardcore poor non-Malays. In the hardcore poor group, Malay ethnicity was associated with higher prevalence of cognitive impairment but lower prevalence of depression risk and multimorbidity. In the Malay group, hardcore poor was associated with higher prevalence of cognitive impairment; however, no association was found between hardcore poor with depression risk and multimorbidity after controlling for covariates.
Health outcomes of Malaysian older adults differ according to ethnicity and socioeconomic status. Given the importance of demographic characteristics on health outcomes, design of interventions targeting older adults within multi-ethnic settings must address specific characteristics, especially that of ethnicity and sociodemographic status so as to fulfil their needs. Several implications for future practice were discussed.
