Racial and socioeconomic disparities in pediatric heart transplant outcomes in the era of anti-thymocyte globulin induction.

BACKGROUND: Black race is associated with worse outcomes across solid organ transplantation. Augmenting immunosuppression through antithymocyte globulin (ATG) induction may mitigate organ rejection and graft loss. We investigated whether racial and socioeconomic outcome disparities persist in children receiving ATG induction. METHODS: Using the Pediatric Heart Transplant Society registry, we compared outcomes in Black and White children who underwent heart transplant with ATG induction between 2000 and 2020. The primary outcomes of treated rejection, rejection with hemodynamic compromise (HC), and graft loss (death or re-transplant). We explored the association of these outcomes with race and socioeconomic disparity, assessed using a neighborhood deprivation index [NDI] score at 1-year post-transplant (high NDI score implies more socioeconomic disadvantage). RESULTS: The study cohort included 1,719 ATG-induced pediatric heart transplant recipients (22% Black, 78% White). There was no difference in first year treated rejection (Black 24.5%, White 28.1%, p = 0.2). During 10 year follow up, the risk of treated rejection was similar; however, Black recipients were at higher risk of HC rejection (p = 0.009) and graft loss (p = 0.02). Black recipients had a higher mean NDI score (p < 0.001). Graft loss conditional on 1-year survival was associated with high NDI score in both White and Black recipients (p < 0.0001). In a multivariable Cox model, both high NDI score (HR 1.97, 95% CI 1.23-3.17) and Black race (HR 2.22, 95% CI 1.40-3.53) were associated with graft loss. CONCLUSION: Black race and socioeconomic disadvantage remain associated with late HC rejection and graft loss in children with ATG induction. These disparities represent important opportunities to improve long term transplant outcomes.

Examining racial and socioeconomic disparity in the pediatric heart transplant evaluation.

Racial disparities have been reported among pediatric patients waitlisted for and undergoing heart transplantation but have not been studied further upstream in the transplant candidate evaluation process. We retrospectively studied our single-center experience in order to investigate any potential biases in the evaluation process. Results of the heart transplant evaluation in children ≤18 years old at our institution were analyzed. Primary outcome was final disposition to waitlist or not. Race was defined by family self-identification. Descriptive and comparative statistical analyses were performed. From 2013 to 2019, 133 unique patients were referred for listing consideration. While Black patients comprised 44% of the referral population and had more markers of socioeconomic disadvantage, they comprised 43% of the patients who were listed for transplantation with no significant difference between these proportions (p = .96). Black and White patients made up a similar proportion of patients deemed too well or too ill for listing. Black patients had lower annual household income estimates and rates of household marriage. Despite identifying significant social challenges in 27 patients (18 of them Black), only five patients (3 Black and 2 White) were turned down for listing due to social barriers. While limited by the small number of patients turned down for social barriers, our transplant evaluation process does not appear to result in racial disparities in access to listing. Further studies are needed using national cohorts to explore possible racial disparities upstream from waitlisting and transplantation, such as during the referral and evaluation.

Kawasaki Disease and Clinical Outcome Disparities Among Black Children.

OBJECTIVE: To determine whether Black children with Kawasaki disease exhibit disparities in prevalence, sequelae, and response to intravenous gamma globulin (IVIG) treatment. STUDY DESIGN: International Classification of Diseases codes were used to identify children with Kawasaki disease admitted to a tertiary center in the southeastern US. Subjects diagnosed and treated according to American Heart Association criteria were included. Demographic, laboratory, clinical, and echocardiographic data from the electronic medical record (2000-2015) were compared between Blacks and Whites. RESULTS: Data from 369 subjects (52% Whites and 48% Blacks) were included in our analysis. No significant differences related to timely admission, IVIG treatment, or coronary artery (CA) abnormalities during hospitalization were observed. Blacks showed lower IVIG response rates than Whites for patients administered IVIG within 10 days of fever onset (86.6% vs 95.6%; P = .007). Blacks received more ancillary drugs (9.6% vs 2.6%; P = .003), and endured longer hospitalizations (mean, 5 ± 3.9 days vs 3.4 ± 2.2 days; P = .001). Blacks presented with higher C-reactive protein level and erythrocyte sedimentation rate and lower hemoglobin, albumin, and sodium levels. Blacks had a higher proportion of persistent CA abnormalities than Whites at second follow-up echocardiogram (14.5% vs 6.3%; P = .03), and at third follow-up echocardiogram (21.2% vs 6.9%; P = .01). CONCLUSIONS: Compared with White children, Black children with Kawasaki disease had higher IVIG refractory prevalence, more severe inflammation, more ancillary treatments, and longer hospitalizations. Despite no racial differences in time to diagnosis or initial treatment, there was greater CA abnormality persistence among Black children at follow-up.

Sociodemographic factors, health seeking behaviors, reproductive history, and knowledge of cervical screening among women in Swaziland.

BACKGROUND: Cervical cancer is the leading cause of cancer among women in Swaziland; however, a low rate of cervical screening in this population has led to high rates of morbidity and mortality from cervical cancer. OBJECTIVE: To identify factors associated with lack of cervical screening among women in Swaziland. METHODS: A cross-sectional study was conducted among 300 women aged 18-69 years attending clinics in three regions of Swaziland from May to August of 2014. An investigator-administered questionnaire was used to collect data on socioeconomic factors, health-seeking behaviors, reproductive history, and cervical screening history and knowledge from the women. RESULTS: Adjusted multivariable logistic regression analysis revealed that women < 30 years of age were less likely to receive a cervical exam compared to women ≥30 years of age (Odds Ratio 0.06, 95% Confidence Interval 0.01-0.67). Women who had a tertiary education were almost 6 times more likely to receive a cervical screening (OR 5.83, 95% CI 1.11-30.50). Women who said that they did not know when to receive cervical screening were 73% less likely to have a cervical exam (OR 0.27, 95% CI 0.01-0.74). CONCLUSIONS: Younger age, lower educational level, and lack of knowledge about when to receive a cervical screening affected whether women obtained a cervical screening. This indicates the need for educating women, particularly younger women, about the importance of cervical examinations. Addressing these barriers to screening should lead to a decrease in cervical lesions and cancer, especially in this high HIV-positive population.

Evaluation of Cardiothoracic Surgery Residency and Fellowship Program Websites.

BACKGROUND: The internet is a valuable resource for residency and fellowship applicants when deciding where to apply or interview, yet program websites have shown critical deficiencies in accessibility and content. No analysis of cardiothoracic surgery program websites has been performed. METHODS: Online databases and Google were used to identify integrated, 4 + 3, and traditional cardiothoracic surgery residency and fellowship programs. The accessibility of websites from each of these sources was assessed and the presence or absence of content that may be relevant to applicants was evaluated by two reviewers. RESULTS: Eighty-nine active programs were identified and 86 had functional websites. Website content and accessibility were overall suboptimal in all 86 of these programs. Google was the most reliable means of accessing a program's website. Fifty percent of integrated program websites and 60% of traditional fellowship websites contained less than half of the content assessed. Information on 4 + 3 programs was extremely limited. CONCLUSIONS: Despite the value that a program's website could provide to applicants when making decisions during the application process, cardiothoracic surgery residency and fellowship websites remain difficult to access and are not uniformly providing information that may be important. Improving cardiothoracic website accessibility and content may have implications for attracting the most competitive applicants while limiting the financial and scheduling demands associated with the interview process. Creation of a current database containing standardized information relevant to applicants may improve applicants' ability to form an impression of a program before scheduling an interview.

Twenty-five-Year Follow-up of Short-term Cancer Research Trainees at the University of Alabama at Birmingham: a Brief Report.

Long-term follow-up is needed to evaluate the impact of short-term cancer research programs on the career trajectories of medical and graduate students. Participation in these programs may be crucial in fostering the next generation of cancer research scientists. This report presents the career outcomes and research productivity of 77 medical and public health students with 25 years of tracking data following their participation in a summer cancer research training program at the University of Alabama at Birmingham (UAB) in 1990-1998. Of 64 summer trainees with contact information, complete survey responses were received from 55 (86.0%) individuals. Over half reported clinical care of cancer patients and 18.2% stated that they were engaged in cancer research. Literature searches confirmed that 23.4% (18/77) of trainees have published cancer research papers. Future studies should explore the optimal timing of short-term post-baccalaureate academic cancer training experiences to identify participant characteristics and institutional factors that influence career choices and determine research productivity.
