RESUMEN

PURPOSE: Physical activity is important for enhancing quality of life and cancer control among prostate cancer survivors. The purpose of this study was to characterize adherence to physical activity guidelines among African American and white prostate cancer survivors based on social and clinical determinants and psychosocial factors. METHODS: Observational study of meeting guidelines for moderate intensity physical activity in a retrospective cohort of African American and white prostate cancer survivors (n = 89). RESULTS: Thirty-four percent of survivors met the recommended guidelines for moderate intensity physical activity. There were no racial differences in physical activity between African American and white prostate cancer survivors; however, the likelihood of meeting guidelines was associated significantly with stage of disease, self-rated health, and perceptions of stress. Survivors who had stage pT2c or higher disease had a significantly reduced likelihood of meeting recommended guidelines for physical activity (OR = 0.27, 95% CI = 0.08, 0.86, p = 0.03). The likelihood of meeting guidelines was also reduced among survivors who rated their health as being the same or worse than before they were diagnosed with prostate cancer (OR = 0.32, 95% CI = 0.11, 0.96, p = 0.04). As perceived stress increased, the likelihood of being physically active according to guidelines also decreased (OR = 0.48, 95% CI = 0.26, 0.89, p = 0.02). CONCLUSION: The results of this study underscore the need to develop, implement, and evaluate strategies to enhance physical activity among prostate cancer survivors, regardless of their racial background. Complementary and alternative strategies for physical activity may be one strategy for enhancing activity levels and managing stress among prostate cancer survivors.

RESUMEN

BACKGROUND: The emergence of reactive stroma is a hallmark of prostate cancer (PCa) progression and a potential source for prognostic and diagnostic markers of PCa. Collagen is a main component of reactive stroma and changes systematically and quantitatively to reflect the course of PCa, yet has remained undefined due to a lack of tools that can define collagen protein structure. Here we use a novel collagen-targeting proteomics approach to investigate zonal regulation of collagen-type proteins in PCa prostatectomies. METHODS: Prostatectomies from nine patients were divided into zones containing 0%, 5%, 20%, 70% to 80% glandular tissue and 0%, 5%, 25%, 70% by mass of PCa tumor following the McNeal model. Tissue sections from zones were graded by a pathologist for Gleason score, percent tumor present, percent prostatic intraepithelial neoplasia and/or inflammation (INF). High-resolution accurate mass collagen targeting proteomics was done on a select subset of tissue sections from patient-matched tumor or nontumor zones. Imaging mass spectrometry was used to investigate collagen-type regulation corresponding to pathologist-defined regions. RESULTS: Complex collagen proteomes were detected from all zones. COL17A and COL27A increased in zones of INF compared with zones with tumor present. COL3A1, COL4A5, and COL8A2 consistently increased in zones with tumor content, independent of tumor size. Collagen hydroxylation of proline (HYP) was altered in tumor zones compared with zones with INF and no tumor. COL3A1 and COL5A1 showed significant changes in HYP peptide ratios within tumor compared with zones of INF (2.59 ± 0.29, P value: .015; 3.75 ± 0.96 P value .036, respectively). By imaging mass spectrometry COL3A1 showed defined localization and regulation to tumor pathology. COL1A1 and COL1A2 showed gradient regulation corresponding to PCa pathology across zones. Pathologist-defined tumor regions showed significant increases in COL1A1 HYP modifications compared with COL1A2 HYP modifications. Certain COL1A1 and COL1A2 peptides could discriminate between pathologist-defined tumor and inflammatory regions. CONCLUSIONS: Site-specific posttranslational regulation of collagen structure by proline hydroxylation may be involved in reactive stroma associated with PCa progression. Translational and posttranslational regulation of collagen protein structure has potential for new markers to understand PCa progression and outcomes.

RESUMEN

BACKGROUND: Social isolation is an important social determinant that impacts health outcomes and mortality among patients. The National Academy of Medicine recently recommended that social isolation be documented in electronic health records (EHR). However, social isolation usually is not recorded or obtained as coded data but rather collected from patient self-report or documented in clinical narratives. This study explores the feasibility and effectiveness of natural language processing (NLP) strategy for identifying patients who are socially isolated from clinical narratives. METHOD: We used data from the Medical University of South Carolina (MUSC) Research Data Warehouse. Patients 18 years-of-age or older who were diagnosed with prostate cancer between January 1, 2014 and May 31, 2017 were eligible for this study. NLP pipelines identifying social isolation were developed via extraction of notes on progress, history and physical, consult, emergency department provider, telephone encounter, discharge summary, plan of care, and radiation oncology. Of 4195 eligible prostate cancer patients, we randomly sampled 3138 patients (75%) as a training dataset. The remaining 1057 patients (25%) were used as a test dataset to evaluate NLP algorithm performance. Standard performance measures for the NLP algorithm, including precision, recall, and F-measure, were assessed by expert manual review using the test dataset. RESULTS: A total of 55,516 clinical notes from 3138 patients were included to develop the lexicon and NLP pipelines for social isolation. Of those, 35 unique patients (1.2%) had social isolation mention(s) in 217 notes. Among 24 terms relevant to social isolation, the most prevalent were "lack of social support," "lonely," "social isolation," "no friends," and "loneliness". Among 1057 patients in the test dataset, 17 patients (1.6%) were identified as having social isolation mention(s) in 40 clinical notes. Manual review identified four false positive mentions of social isolation and one false negatives in 154 notes from randomly selected 52 controls. The NLP pipeline demonstrated 90% precision, 97% recall, and 93% F-measure. The major reasons for a false positive included the ambiguities of the experiencer of social isolation, negation, and alternate meaning of words. CONCLUSIONS: Our NLP algorithms demonstrate a highly accurate approach to identify social isolation.

RESUMEN

Prior research and systematic reviews have examined strategies related to weight management, less is known about lifestyle and behavioral counseling interventions optimally suited for implementation in primary care practices generally, and among racial and ethnic patient populations. Primary care practitioners may find it difficult to access and use available research findings on effective behavioral and lifestyle counseling strategies and to assess their effects on health behaviors among their patients. This systematic review compiled existing evidence from randomized trials to inform primary care providers about which lifestyle and behavioral change interventions are shown to be effective for changing patients' diet, physical activity and weight outcomes. Searches identified 444 abstracts from all sources (01/01/2004-05/15/2014). Duplicate abstracts were removed, selection criteria applied and dual abstractions conducted for 106 full text articles. As of June 12, 2015, 29 articles were retained for inclusion in the body of evidence. Randomized trials tested heterogeneous multi-component behavioral interventions for an equally wide array of outcomes in three population groups: diverse patient populations (23 studies), African American patients only (4 studies), and Hispanic/Mexican American/Latino patients only (2 studies). Significant and consistent findings among diverse populations showed that weight and physical activity related outcomes were more amenable to change via lifestyle and behavioral counseling interventions than those associated with diet modification. Evidence to support specific interventions for racial and ethnic minorities was promising, but insufficient based on the small number of studies.

RESUMEN

Implementing behavioral interventions for cardiovascular risk reduction and weight management is challenging in primary care. Primary care patients and providers were recruited for qualitative interviews to identify priorities and preferences for addressing weight management. Thematic analysis was used to identify relevant resources, barriers to lifestyle modification, health behavior change, and implementation of weight management strategies into care. Patients and providers prioritized increasing physical activity and healthy diets when managing chronic disease; and reported decreased patient motivation, knowledge, and limited organizational capacity and time among providers to deliver intensive interventions. Providers and patients disagreed regarding who owns accountability for weight management.

RESUMEN

We examined beliefs about genetically targeted care (GTC) among African American men and women in a hospital-based sample and identified sociodemographic, cultural, and clinical factors having significant independent associations with these beliefs. Specifically, beliefs about GTC were evaluated after respondents were randomly primed with a racial or non-racial cue about race and genetics. Despite priming with a racial or non-racial cue, many respondents had positive beliefs about GTC. But, 49% believed that GTC would limit access to medical treatment, 46% believed that people will not trust GTC, and 20% believed that people like them would not benefit from GTC. Racial and non-racial priming did not have significant associations with negative beliefs about GTC. However, cultural beliefs related to temporal orientation were associated significantly with believing that genetically targeted care will limit access to medical treatment. Greater levels of future temporal orientation were associated with a reduced likelihood of endorsing this belief (OR = 0.70, 95% CI = 0.49, 1.01, p = 0.05). Respondents who had a chronic medical condition had an almost three-fold greater likelihood of believing that they would not benefit from GTC (OR = 2.90, 95% CI = 1.00, 8.37, p = 0.05). Greater exposure to information about genetic testing for chronic conditions was also associated with a reduced likelihood of believing that they would not benefit from GTC (OR = 0.40, 95% CI = 0.64, 0.91, p = 0.02). African Americans have diverse beliefs about GTC that should be considered as genetic and genomic services are offered.

RESUMEN

Social determinants are important to cancer screening among African Americans. To evaluate the association between social determinants (e.g., psychological characteristics, perceived social environment, cultural beliefs such as present temporal orientation) and colorectal cancer (CRC) screening among African Americans. African American adults (n = 262) ages 50-75 completed a telephone interview. Multivariate logistic regression analysis was used to identify factors having significant independent associations with CRC screening. Only 57% of respondents reported having CRC screening. The likelihood of screening increased with greater neighborhood satisfaction (OR = 1.38, 95% CI = 1.01, 1.90, p = 0.04), older age (OR = 1.75, 95% CI = 1.24, 2.48, p = 0.002), greater self-efficacy (OR = 2.73, 95% CI = 1.40, 5.35, p = 0.003), and health care provider communication (OR = 10.78, 95% CI = 4.85, 29.94, p = 0.0001). Community resources are important precursors to CRC screening and outcomes among African Americans. In addition to addressing psychological factors and patient-provider communication, efforts to ensure the availability of quality health care facilities that provide CRC screening in the neighborhoods where African Americans live are needed.

RESUMEN

The US is experiencing a severe shortage of underrepresented biomedical researchers. The purpose of this paper is to present two case examples of cancer research mentoring programs for underrepresented biomedical sciences students. The first case example is a National Institutes of Health/National Cancer Institute (NIH/NCI) P20 grant titled "South Carolina Cancer Disparities Research Center (SC CaDRe)" Training Program, contributing to an increase in the number of underrepresented students applying to graduate school by employing a triple-level mentoring strategy. Since 2011, three undergraduate and four graduate students have participated in the P20 SC CaDRe program. One graduate student published a peer-reviewed scientific paper. Two graduate students (50 %) have completed their master's degrees, and the other two graduate students will receive their degrees in spring 2015. Two undergraduate students (67 %) are enrolled in graduate or professional school (grad./prof. school), and the other graduate student is completing her final year of college. The second case example is a prostate cancer-focused Department of Defense grant titled "The SC Collaborative Undergraduate HBCU Student Summer Training Program," providing 24 students training since 2009. Additionally, 47 students made scientific presentations, and two students have published peer-reviewed scientific papers. All 24 students took a GRE test preparation course; 15 (63 %) have applied to graduate school, and 11 of them (73 %) are enrolled in grad./prof. school. Thirteen remaining students (54 %) are applying to grad./prof. school. Leveraged funding provided research-training opportunities to an additional 201 National Conference on Health Disparities Student Forum participants and to 937 Ernest E. Just Research Symposium participants at the Medical University of South Carolina.

RESUMEN

Background/Objective: Linking data is a critical feature of precision medicine initiatives that involves integrating information from multiple sources to improve researchers' and clinicians' ability to deliver care. We have limited understanding of how individuals perceive linking data as it relates to precision medicine. The aim of this study was to identify how sociodemographics, comorbidities, and beliefs about precision medicine influence two outcomes related to linking data: beliefs about linking data and concerns about linking data among men. Methods: We recruited 124 adult men from primary care practices at a large clinical research university to complete a cross-sectional survey that included questions about sociodemographic characteristics, comorbidities, beliefs, benefits, and limitations of precision medicine, and two outcomes of interest: beliefs about the value of linking data and concerns about linking data. Descriptive statistics, bivariate associations, and multivariable regression were conducted. Results: Participants had positive beliefs about linking data for precision medicine (M = 4.05/5) and average concern about linking data (M = 2.1/5). Final multivariable models revealed that higher levels of loneliness are associated with more positive beliefs about linking data (ß = 0.41, p = 0.027). Races other than African American (ß = -0.64, p = 0.009) and those with lower perceived limitations of precision medicine were less likely to be concerned about linking data (ß = -0.75, p = 0.0006). Conclusion: Our results advance the literature about perceptions of linking data for use in clinical and research studies among men. Better understanding of factors associated with more positive perceptions of data linkages could help improve how researchers recruit and engage participants.

RESUMEN

Background: A better understanding of neighborhood-level factors' contribution is needed in order to increase the precision of cancer control interventions that target geographic determinants of cancer health disparities. This study characterized the distribution of neighborhood deprivation in a racially diverse cohort of prostate cancer survivors. Methods: A retrospective cohort of 253 prostate cancer patients who were treated with radical prostatectomy from 2011 to 2019 was established at the Medical University of South Carolina. Individual-level data on clinical variables (e.g., stage, grade) and race were abstracted. Social Deprivation Index (SDI) and Healthcare Professional Shortage (HPS) status was obtained from the Robert Graham Center and assigned to participants based on their residential census tract. Data were analyzed with descriptive statistics and multivariable logistic regression. Results: The cohort of 253 men consisted of 168 white, 81 African American, 1 Hispanic and 3 multiracial men. Approximately 49% of 249 men lived in areas with high SDI (e.g., SDI score of 48 to 98). The mean for SDI was 44.5 (+27.4), and the range was 97 (1−98) for all study participants. African American men had a significantly greater likelihood of living in a socially deprived neighborhood compared to white men (OR = 3.7, 95% C.I. 2.1−6.7, p < 0.01), while men who lived in areas with higher HPS shortage status were significantly more likely to live in a neighborhood that had high SDI compared to men who lived in areas with lower HPS shortages (OR = 4.7, 95% C.I. = 2.1−10.7, p < 0.01). African Americans had a higher likelihood of developing biochemical reoccurrence (OR = 3.7, 95% C.I. = 1.7−8.0) compared with white men. There were no significant association between SDI and clinical characteristics of prostate cancer. Conclusions: This study demonstrates that SDI varies considerably by race among men with prostate cancer treated with radical prostatectomy. Using SDI to understand the social environment could be -particularly useful as part of precision medicine and precision public health approaches and could be used by cancer centers, public health providers, and other health care specialists to inform operational decisions about how to target health promotion and disease prevention efforts in catchment areas and patient populations.

RESUMEN

African-Americans experience a disproportionate share of thoracic cancer burden compared to Whites. Low socioeconomic status (SES) and race are factors in low clinical trial enrollment, accounting for the disparities between African-Americans and Whites. Less than 3% of newly diagnosed cancer patients enroll in clinical trials, and of that number, only 10% represent ethnic minorities. The value of clinical trials research is not generalizable without sufficient representation by ethnic minorities. Patient navigation, an intervention designed to ensure timely and efficient access to healthcare, may improve clinical trial enrollment among African-Americans in lung and esophageal trials by influencing a patient's perception of clinical trials. The lack of navigation programs and training may negatively influence standardization of navigation techniques. The purpose of this project was to deliver and evaluate an evidence-based navigation-training curriculum for "lay" navigators. The primary outcomes measured were confidence in the role as navigator, understanding a navigator's role, and knowledge and perception of clinical trials. The results revealed overall confidence in the role as lay navigators increased from pre-to-post test. Lessons learned included the need for preparatory classes to build the navigator's confidence, and additional training components in death and dying. A larger study is warranted to confirm the findings.

RESUMEN

The purpose of this study was to examine the association between neighborhood social deprivation and individual-level characteristics on breast cancer staging in African American and white breast cancer patients. We established a retrospective cohort of patients with breast cancer diagnosed from 1996 to 2015 using the South Carolina Central Cancer Registry. We abstracted sociodemographic and clinical variables from the registry and linked these data to a county-level composite that captured neighborhood social conditions-the social deprivation index (SDI). Data were analyzed using chi-square tests, Student's t-test, and multivariable ordinal regression analysis to evaluate associations. The study sample included 52,803 female patients with breast cancer. Results from the multivariable ordinal regression model demonstrate that higher SDI (OR = 1.06, 95% CI: 1.02-1.10), African American race (OR = 1.35, 95% CI: 1.29-1.41), and being unmarried (OR = 1.17, 95% CI: 1.13-1.22) were associated with a distant stage at diagnosis. Higher tumor grade, younger age, and more recent year of diagnosis were also associated with distant-stage diagnosis. As a proxy for neighborhood context, the SDI can be used by cancer registries and related population-based studies to identify geographic areas that could be prioritized for cancer prevention and control efforts.

RESUMEN

PURPOSE: The purpose of this study was to examine racial differences in patient portal activation and research participation among patients with prostate cancer. MATERIALS AND METHODS: Participants were African American and White patients with prostate cancer who were treated with radical prostatectomy (n = 218). Patient portal activation was determined using electronic health records, and research participation was measured based on completion of a social determinants survey. RESULTS: Thirty-one percent of patients completed the social determinants survey and enrolled in the study and 66% activated a patient portal. The likelihood of enrolling in the study was reduced with greater levels of social deprivation (odds ratio [OR], 0.70; 95% CI, 0.50 to 0.98; P = .04). Social deprivation also had a signification independent association with patient portal activation along with racial background. African American patients (OR, 0.48; 95% CI, 0.23 to 0.91; P = .02) and those with greater social deprivation (OR, 0.58; 95% CI, 0.42 to 0.82; P = .002) had a lower likelihood of activating a patient portal compared with White patients and those with lower social deprivation. CONCLUSION: Although the majority of patients with prostate cancer activated their patient portal, rates of patient portal activation were lower among African American patients and those who lived in areas with greater social deprivation. Greater efforts are needed to promote patient portal activation among African American patients with prostate cancer and address access to health information technology among those who live in socially disadvantaged geographic areas.

RESUMEN

An emerging theory about racial differences in cancer risk and outcomes is that psychological and social stressors influence cellular stress responses; however, limited empirical data are available on racial differences in cellular stress responses among men who are at risk for adverse prostate cancer outcomes. In this study, we undertook a systems approach to examine molecular profiles and cellular stress responses in an important segment of African American (AA) and European American (EA) men: men undergoing prostate biopsy. We assessed the prostate transcriptome with a single biopsy core via high throughput RNA sequencing (RNA-Seq). Transcriptomic analyses uncovered impacted biological pathways including PI3K-Akt signaling pathway, Neuroactive ligand-receptor interaction pathway, and ECM-receptor interaction. Additionally, 187 genes mapping to the Gene Ontology (GO) terms RNA binding, structural constituent of ribosome, SRP-dependent co-translational protein targeting to membrane and the biological pathways, translation, L13a-mediated translational silencing of Ceruloplasmin expression were differentially expressed (DE) between EA and AA. This signature allowed separation of AA and EA patients, and AA patients with the most severe clinical characteristics. AA patients with elevated expression levels of this genomic signature presented with higher Gleason scores, a greater number of positive core biopsies, elevated dehydroepiandrosterone sulfate levels and serum vitamin D deficiency. Protein-protein interaction (PPI) network analysis revealed a high degree of connectivity between these 187 proteins.

RESUMEN

Chronic refractory angina can lead to multiple acute hospital admissions. This can be due to patient and healthcare professional misconceptions regarding the meaning of the chest pain experienced. Symptom control, psychological support and education form an important part of the management of this condition. We describe a case study where intranasal alfentanil provided rapid relief of symptoms preventing repeated hospital admissions.

RESUMEN

Objective: To examine the relationships between resiliency, sociodemographic factors, and allostatic load among male Veterans. Design/Study Participants: Cross-sectional study with minority (African American or Hispanic) and non-minority (White) male Veterans undergoing prostate biopsy. Setting: Veterans Affairs Medical Center located in Charleston, SC. Main Outcome Measures: Self-reported resilience measured using the two item sub-scale from the Connor-Davidson Resiliency Scale and allostatic load determined from biomarkers measured in blood. Results: In this small sample, bounce-back resilience and allostatic load level had a significant negative correlation, while adaptation resilience and allostatic load were slightly correlated, but the association was not statistically significant. Sixty-six percent of participants reported that they were able to adapt and 40% reported they were able to bounce back. Higher income and lower PSA level were significantly correlated with greater adaptation resilience. Minority men were significantly more likely than non-minority men to report that they are able to bounce back. Married men were also significantly more likely than unmarried men to report that they were able to bounce back. Conclusion: It may be important to target resiliency training programs to Veterans based on their social determinants and to examine the effects of these programs on allostatic load.

RESUMEN

Objective: To characterize rates of co-morbidity among prostate cancer patients treated with radical prostatectomy and to examine the association between co-morbidity status and race, clinical factors, and health behaviors for cancer control. Design/Study Participants: Retrospective cohort study among prostate cancer patients treated with radical prostatectomy. Setting: Academic medical center located in the southeastern region of the United States. Main Outcome Measure: Patients with at least one of five co-morbid conditions considered were categorized as having a co-morbidity, and those without any were categorized as not having a co-morbid condition. Co-morbid conditions considered were hypertension, diabetes, heart problems, stroke, and high cholesterol, which had been recorded in the electronic medical record as part of their past medical history. Results: Fifty-one percent of participants had a co-morbidity, with hypertension being the most common. The average number of co-morbidities among study participants was .87. In a multivariate logistic regression analysis, being diagnosed with prostate cancer within the past four years was associated with an increased likelihood of having a co-morbidity (OR=4.71, 95% CI=2.69, 8.25, P=.0001) compared with diagnosis five or more years ago. Age was also associated with an increased likelihood of having a co-morbidity (OR=1.30, 95% CI=1.005, 1.68, P=.05). In this study cohort, race, stage at diagnosis, and PSA level were not statistically associated with co-morbidity status. Conclusion: Better chronic disease management is needed among prostate cancer survivors through more effective survivorship care planning and interventions that promote health behaviors.

RESUMEN

OBJECTIVES: Physiological stress responses have been suggested as a mechanism through which social and biological factors contribute to racial disparities in breast cancer outcomes. Many African Americans experience stressful life events and circumstances. These social factors may contribute to an increased risk of advanced stage disease at diagnosis and/or faster progression, but not all African American women exposed to adverse social factors develop advanced stage disease. Similarly, women who have a limited number of stressors can develop advanced stage breast cancer. Highly individualized stress reactivity may account for these inconsistent associations. METHOD: This report describes the rationale, design, and methods for an exploratory study that uses the experimental medicine approach to: (a) characterize the nature and distribution of stress reactivity among African American breast cancer survivors based on socioeconomic, clinical, and social stressors; (b) examine the impact of stress reactivity on temporal discounting; and (c) determine the extent to which stress reactivity and temporal discounting are associated with adherence to recommendations for cancer control behaviors and treatment compliance as part of the Science of Behavior Change Network. RESULTS: This study addresses several empirical gaps about the most effective ways to develop behavior change interventions for a medically underserved population that continues to experience disparities in cancer morbidity and mortality. CONCLUSIONS: Results from this research will provide the empirical and conceptual basis for future intervention protocols that target mechanisms that are critical to disparities in African American breast cancer survivors.

RESUMEN

PURPOSE: To examine financial toxicity and strain among men in an equal access healthcare system based on social determinants and clinical characteristics. METHODS: Observational study among men receiving prostate cancer care (n = 49) at a Veterans Health Administration (VHA) facility. Financial hardship included overall financial strain and financial toxicity due to healthcare costs. Financial strain was measured with one item asking how much money they have leftover at the end of the month. Financial toxicity was measured with the Comprehensive Score for Financial Toxicity (COST) scale. RESULTS: Comprehensive Score for Financial Toxicity scores among participants indicated moderate levels of financial toxicity (M = 24.4, SD = 9.9). For financial strain, 36% of participants reported that they did not have enough money left over at the end of the month. There were no racial or clinically related differences in financial toxicity, but race and income level had significant associations with financial strain. CONCLUSION: Financial toxicity and strain should be measured among patients in an equal access healthcare system. Findings suggest that social determinants may be important to assess, to identify patients who may be most likely to experience financial hardship in the context of obtaining cancer care and implement efforts to mitigate the burden for those patients.
