RESUMEN
Racism has been a long-standing influential factor that has negatively impacted both past and current health disparities within the United Sates population. Existing problems of racism and its impact on both health disparities and health inequalities were only amplified during the COVID-19 pandemic. The pandemic allowed both clinicians and researchers to recognize a growing list of health concerns at the macro-, meso-, and micro-level among underserved racially minoritized patients with specific chronic illnesses such as cancer. Based on these concerns, this Special Issue was designed to highlight the challenges of cancer screening, cancer treatment, and cancer-centered educational outreach among racially minoritized communities.

This scoping review provides an overview of cancer interventions implemented with Arab Americans across the cancer control continuum, including an examination of outcomes and implementation processes. The search strategy included database searching and reviewing reference lists and forward citations to identify articles describing interventions with Arab adults living in the US, with no restrictions on date of publication or research methodology. The review included 23 papers describing 12 unique cancer interventions. Most interventions focused on individual-level determinants of breast and cervical cancer screening; used non-quasi-experimental research designs to evaluate intervention effectiveness; and demonstrated improvements in short-term cancer screening knowledge. Implementation processes were less commonly described. Most interventions were culturally and linguistically tailored to communities of focus; were delivered in educational sessions in community settings; engaged with the community mostly for recruitment and implementation; and were funded by foundation grants. Suggestions for research and intervention development are discussed.

OBJECTIVES: A major strategy to reduce the impact of breast cancer (BC) among African Americans (AA) is patient navigation, defined here as individualized assistance for reducing barriers to healthcare use. The primary focus of this study was to estimate the added value of incorporating breast health promotion by navigated participants and the subsequent BC screenings that network members may obtain. METHODS: In this study, we compared the cost-effectiveness of navigation across 2 scenarios. First, we examine the effect of navigation on AA participants (scenario 1). Second, we examine the effect of navigation on AA participants and their networks (scenario 2). We leverage data from multiple studies in South Chicago. Our primary outcome (BC screening) is intermediate, given limited available quantitative data on the long-term benefits of BC screening for AA populations. RESULTS: When considering participant effects alone (scenario 1), the incremental cost-effectiveness ratio was $3845 per additional screening mammogram. When including participant and network effects (scenario 2), the incremental cost-effectiveness ratio was $1098 per additional screening mammogram. CONCLUSION: Our findings suggest that inclusion of network effects can contribute to a more precise, comprehensive assessment of interventions for underserved communities.

This quantitative study examined the presence of culturally relevant health messages for African-Americans based on a preexisting dataset from 21 African-American churches in South Carolina (USA). Content analysis served as the primary methodological approach to code printed media messages based on their cultural relevance among African-Americans (Cohen's kappa = .74). Within the dataset (n = 2166), 477 (22%) items were identified as culturally relevant. A low prevalence of culturally relevant messages was found across the three message topics, two media types, and one media source. Due to the limited presence of culturally relevant messages, researchers should collaborate with African-American churches to design health promotion messages.

African American (AA) women experience much greater mortality due to breast cancer (BC) than non-Latino Whites (NLW). Clinical patient navigation is an evidence-based strategy used by healthcare institutions to improve AA women's breast cancer outcomes. While empirical research has demonstrated the potential effect of navigation interventions for individuals, the population-level impact of navigation on screening, diagnostic completion, and stage at diagnosis has not been assessed. An agent-based model (ABM), representing 50-74-year-old AA women and parameterized with locally sourced data from Chicago, is developed to simulate screening mammography, diagnostic resolution, and stage at diagnosis of cancer. The ABM simulated three counterfactual scenarios: (1) a control setting without any navigation that represents the "standard of care"; (2) a clinical navigation scenario, where agents receive navigation from hospital-affiliated staff; and (3) a setting with network navigation, where agents receive clinical navigation and/or social network navigation (i.e., receiving support from clinically navigated agents for breast cancer care). In the control setting, the mean population-level screening mammography rate was 46.3% (95% CI: 46.2%, 46.4%), the diagnostic completion rate was 80.2% (95% CI: 79.9%, 80.5%), and the mean early cancer diagnosis rate was 65.9% (95% CI: 65.1%, 66.7%). Simulation results suggest that network navigation may lead up to a 13% increase in screening completion rate, 7.8% increase in diagnostic resolution rate, and a 4.9% increase in early-stage diagnoses at the population-level. Results suggest that systems science methods can be useful in the adoption of clinical and network navigation policies to reduce breast cancer disparities.

OBJECTIVES: Despite the benefits of genetic counseling and testing (GCT), utilization is particularly low among African American (AA) women who exhibit breast cancer features that are common in BRCA-associated cancer. Underutilization is especially problematic for AA women who are more likely to die from breast cancer than women from any other race or ethnicity. Due to medical mistrust, fear, and stigma that can be associated with genetic services among racial/ethnic minorities, reliance on trusted social networks may be an impactful strategy to increase dissemination of knowledge about hereditary cancer risk. Informed by the social cognitive theory, the purpose of this study is to determine: 1) which AA patients diagnosed with breast cancer and with identified hereditary risk are sharing information about hereditary risk with their networks; 2) the nature of the information dissemination; and 3) if personal GCT experiences is associated with dissemination of information about hereditary risk. METHODS: Among consented participants (n = 100) that completed an interview administered using a 202-item questionnaire consisting of open- and closed-ended questions, 62 patients were identified to be at higher risk for breast cancer. Descriptive statistics, bivariable chi-square, Pearson's exact tests, and regression analyses were conducted to examine differences in characteristics between high-risk participants who disseminated hereditary risk information and participants who did not. RESULTS: Among high-risk participants, 25 (40%) indicated they had disseminated information about hereditary risk to at least one member in their family/friend network and 37 (60%) had not. Receipt of both provider recommendations and receipt of GCT services was associated with greater odds of disseminating information about hereditary risk with networks, OR = 4.53, 95%CI [1.33, 15.50], p = .02. CONCLUSION: Interventions that increase self-efficacy gained through additional personalized knowledge and experience gained through provider recommendations and by undergoing GCT may facilitate information dissemination among social/familial networks.

BACKGROUND: Robotic surgery for colorectal pathology has gained interest as it can overcome technical challenges and limitations of traditional laparoscopic surgery. A lack of training and costs have been cited as reasons for limiting its use in Canada. The objective of this paper was to assess the impact of robotic surgery on outcomes and costs in a Canadian setting. METHODS: This is a retrospective study of consecutive patients undergoing left sided colorectal surgery ("Pre-Robotic Phase" n = 145 vs. "Post Robotic Phase" n = 150) and a single tertiary care centre in Ontario, Canada. Utilization and success of minimally invasive surgery (MIS), length of stay, complications and hospital costs were compared. Univariate and Multivariate analysis was used for these comparisons. RESULTS: Characteristics, diagnosis and type of resection were similar between groups. Robotic Implementation resulted in higher rates of successful MIS (i.e. attempt at MIS without conversion) (85% vs. 47%, P < 0.001), shorter mean length of stay (4.7 days vs. 8.4 days, P < 0.001), and similar mean operative times (3.9 h vs. 3.9 h, P = 0.93). Emergency Department visits were fewer in the Robotic Phase (24% vs. 34%, P = 0.04), with no difference in readmission, anastomotic leak or unplanned reoperation. After robotic implementation, the mean total hospital costs decreased, but this was not statistically significant (-$1453, 95% CI -$3974 to +$1068, P = 0.25). Regression analysis, adjusting for age, gender, obesity, ASA and procedure showed similar findings (Robotic Phase -$657, 95% CI -$3038 to +$1724, vs Pre Robotic Phase [Reference], P = 0.59). INTERPRETATION: Implementation of a robotic colorectal surgery program in a Canadian tertiary care centre showed improved clinical outcomes, without a significant increase in the cost of care. Although this study is from a single institution, we have demonstrated that robotic colorectal surgery is feasible and can be cost effective in the right setting.

BACKGROUND: Patient navigation is an increasingly widespread intervention to address the persistent, severe, and disproportionate breast cancer (BC) burden that African Americans (AA) face. Navigation may have more widespread effects than previously estimated due to patient-driven diffusion of BC information. METHODS: This pilot study examined the network effects of a randomized controlled trial via recruitment of navigated and non-navigated AA BC patients as well as their network members. We estimated study arm differences in patient BC promotion (i.e., number of individuals to whom BC patients promote BC screening) and network BC screening (i.e., % BC screening among network members). RESULTS: Among our sample of 100 AA BC patients, navigated patients promoted BC screening to more individuals than non-navigated patients. BC patients were more likely to promote BC screening to children and individuals with whom they communicated more frequently. Some models further suggested more network BC screening among "navigated" network members relative to "non-navigated" network members. CONCLUSIONS: Navigated AA patients promoted BC screening more widely throughout their networks than non-navigated AA BC patients. There were also suggestive findings regarding increased BC screening among their network members. Our pilot study highlights the potential for social network analysis to improve the precision of intervention effect estimates and to inform future innovations (e.g., integrating navigation and network-based interventions) with multilevel effects on cancer health disparities.

PURPOSE: Social support improves several quality of life (QOL) domains among African American breast cancer survivors. How different dimensions of social support are associated with QOL among African American breast cancer survivors may however differ from other populations. This study explores this hypothesis by examining associations of positive social support (supportive interactions that promote affection) and negative social support (non-supportive interactions wherein the provider of support may not have the best intended actions) with QOL among Chicago-based African American breast cancer survivors. METHODS: Study participants were eligible if they (1) were identified as being an African American female, (2) were at least 18 years of age or older, and (3) were diagnosed with breast cancer during or after navigation was implemented at the study hospital. Participants completed validated questionnaires via telephone or in-person interviews. RESULTS: Among our sample of 100 participants, positive support was associated with greater mental well-being in non-imputed (Std ß=1.60, CI: 0.51, 2.69, p= 0.004) and imputed models (Std ß= 1.67, CI: 0.68, 2.73, p=0.001). There was also a weaker inverse association with negative support and mental well-being when using non-imputed data (Std ß=-0.82, CI:-1.65, 0.02, p= 0.05). CONCLUSIONS: Our findings suggest that positive support, in particular, is highly influential for improving mental well-being among African American breast cancer survivors. Simultaneously, negative support appears to be an independent, albeit weaker, determinant of mental well-being.

Motor learning is a lifelong process. However, age-related changes to musculoskeletal and sensory systems alter the relationship (or mapping) between sensory input and motor output, and thus potentially affect motor learning. Here we asked whether age affects the ability to adapt to and retain a novel visuomotor mapping learned during overground walking. We divided participants into one of three groups (n = 12 each) based on chronological age: a younger-aged group (20-39 years old); a middle-aged group (40-59 years old); and an older-aged group (60-80 years old). Participants learned a new visuomotor mapping, induced by prism lenses, during a precision walking task. We assessed retention one-week later. We did not detect significant effects of age on measures of adaptation or savings (defined as faster relearning). However, we found that older adults demonstrated reduced initial recall of the mapping, reflected by greater foot-placement error during the first adaptation trial one-week later. Additionally, we found that increased age significantly associated with reduced initial recall. Overall, our results suggest that aging does not impair adaptation and that older adults can demonstrate visuomotor savings. However, older adults require some initial context during relearning to recall the appropriate mapping.

PURPOSE: We explored relationships between patient-provider communication quality (PPCQ) and three quality of life (QOL) domains among self-identified rural cancer survivors: social well-being, functional well-being, and physical well-being. We hypothesized that high PPCQ would be associated with greater social and functional well-being, but be less associated with physical well-being, due to different theoretical mechanisms. METHODS: All data were derived from the 2017-2018 Illinois Rural Cancer Assessment (IRCA). To measure PPCQ and QOL domains, we respectively used a dichotomous measure from the Medical Expenditure Panel Survey's Experience Cancer care tool (high, low/medium) and continuous measures from the Functional Assessment of Cancer Therapy-General (FACT-G). RESULTS: Our sample of 139 participants was largely female, non-Hispanic White, married, and economically advantaged. After adjusting for demographic and clinical variables, patients who reported high PPCQ exhibited greater social well-being (Std. ß = 0.20, 95% CI: 0.03, 0.35, p = 0.02) and functional well-being (Std. ß = 0.20, 95% CI: 0.05, 0.35, p = 0.03) than patients with low/medium PPCQ. No association was observed between PPCQ and physical well-being (Std. ß = 0.06, 95% CI: - 2.51, 0.21, p = 0.41). Sensitivity analyses found similar, albeit attenuated, patterns. CONCLUSION: Our findings aligned with our hypotheses. Future researchers should explore potential mechanisms underlying these differential associations. Specifically, PPCQ may be associated with social and functional well-being through interpersonal mechanisms, but may not be as associated with physical well-being due to multiple contextual factor rural survivors disproportionately face (e.g., limited healthcare access, economic hardship) and stronger associations with clinical factors.

BACKGROUND: Social needs may affect cancer survivors' health-related quality of life (HRQOL) above and beyond sociodemographic and cancer-related factors. The purpose of this study was to estimate associations between social needs and HRQOL. METHODS: Results included data from 1754 participants in the Detroit Research on Cancer Survivors cohort, a population-based study of African American survivors of breast, colorectal, lung, and prostate cancer. Social needs included items related to food insecurity, utility shutoffs, housing instability, not getting health care because of cost or a lack of transportation, and perceptions of neighborhood safety. HRQOL was measured with the validated Functional Assessment of Cancer Therapy-General (FACT-G). Linear regression models controlled for demographic, socioeconomic, and cancer-related factors. RESULTS: More than one-third of the survivors (36.3%) reported social needs including 17.1% of survivors reported 2 or more. The prevalence of social needs ranged from 14.8% for food insecurity to 8.9% for utility shutoffs. FACT-G score differences associated with social needs were -12.2 (95% confidence interval [CI] to -15.2 to -9.3) for not getting care because of a lack of transportation, -11.3 (95% CI, -14.2 to -8.4) for housing instability, -10.1 (95% CI, -12.7 to -7.4) for food insecurity, -9.8 (95% CI, -12.7 to -6.9) for feeling unsafe in the neighborhood, -8.6 (95% CI, -11.7 to -5.4) for utility shutoffs, and -6.7 (95% CI, -9.2 to -4.1) for not getting care because of cost. CONCLUSIONS: Social needs were common in this cohort of African American cancer survivors and were associated with clinically significant differences in HRQOL. Clinical oncology care and survivorship care planning may present opportunities to screen for and address social needs to mitigate their impact on survivors' HRQOL.

PURPOSE: Clergy have influence on the health of congregations and communities yet struggle with health behaviors. Interventions tailored to their occupation-specific demands and unique needs may provide a solution. Qualitative methods were used to identify opportunities and resources for the development of an effective obesity-related program for clergy. APPROACH: Ninety-minute focus groups were held with clergy (3 groups) and spouses (3 separate groups). Discussion explored: Program target(s); Opportunities and barriers that influence diet, physical activity, and stress-reduction practices; Empowering and culturally relevant health promotion strategies. SETTING: All study activities took place in Memphis, TN. PARTICIPANTS: Eighteen clergy and fourteen spouses participated. All clergy were male, all spouses were female. METHOD: Previous research with clergy informed the interview guide and the PEN-3 framework aided in organizing the coding of clergy and spouse focus groups. Focus groups were audio recorded and transcripts analyzed using NVivo® 12. RESULTS: Themes included: 1) Intervention targets-clergy, spouses, congregations; 2) Opportunities and barriers-making time, establishing boundaries, church traditions, individuals who support and hinder behavior change; 3) Intervention strategies-tools for healthy eating, goal setting, camaraderie, combining face-to-face with eHealth modalities. CONCLUSION: The relationship between clergy, spouse, and congregation make it important for obesity-related programs to target the unique needs of both clergy and spouses. Strategies should focus on healthy eating and personal connections no matter the modality used.

The present study is the first of its kind where oral tissues was fixed, processed and stained with a kitchen microwave in three different thickness. The results obtained was statistically analyzed using IBM SPSS Statistics version 21.0 software. RESULTS: The new technique of fixation, tissue processing and staining using a microwave employed in the present study represented a major change from conventional method and achieved significant reduction in time taken. CONCLUSION: The ease of application and speed of this technique significantly reduced turnaround time in diagnostic labs.
RESUMEN
PURPOSE: Racial/ethnic breast cancer survivorship disparities persist as minority breast cancer survivors (MBCSs) report fragmentation in survivorship care, namely in the access and delivery of survivorship care plans (SCPs). To better understand care coordination of MCBS, this review elucidated concerns of female MBCS about their preparation for post-treatment survivorship care, the preferred practices for the delivery of a SCP, and the associated content to improve post-treatment survivorship care understanding. METHODS: A systematic search of articles from PubMed, Ovid-Medline, CINAHL databases, and bibliographic reviews included manuscripts using keywords for racial/ethnic minority groups and breast cancer survivorship care coordination terms. Salient themes and article quality were analyzed from the extracted data. RESULTS: Fourteen included studies represented 5,854 participants and over 12 racial/ethnic groups. The following themes of post-treatment MBCS were identified from the review: (1) uncertainty about post-treatment survivorship care management is a consequence of sub-optimal patient-provider communication; (2) access to SCPs and related materials are desired, but sporadic; and (3) advancements to the delivery and presentation of SCPs and related materials are desired. CONCLUSIONS: Representation of only 14 studies indicates that the MBCSs' perspective post-treatment survivorship care is underrepresented in the literature. Themes from this review support access to, and implementation of, culturally tailored SCP for MBCS. There was multi-ethnic acceptance of SCPs as a tool to help improve care coordination. IMPLICATIONS FOR CANCER SURVIVORS: These findings highlight the importance of general education about post-treatment survivorship, post-treatment survivorship needs identification, and the elucidation of gaps in effective SCP delivery among MBCS.

PURPOSE: We explored how lifetime comorbidities and treatment-related cancer symptoms were associated with quality of life (QOL) in rural cancer survivors. METHODS: Survivors (n = 125) who were rural Illinois residents aged 18+ years old were recruited from January 2017 to September 2018. We conducted 4 multivariable regressions with QOL domains as outcomes (social well-being, functional well-being, mental health-MHQOL, physical health-PHQOL); the number of physical and psychological comorbidities (e.g., arthritis, high blood pressure, stroke) and treatment-related cancer symptoms (e.g., worrying, feeling sad, lack of appetite, lack of energy) as predictors; and, cancer-related and demographic factors related to these variables as covariates. RESULTS: The number of comorbidities and number of treatment-related symptoms were inversely associated with functional well-being (Std ß = - 0.36, p < 0.0001 and - 0.18, p = 0.03), and MHQOL (Std ß = - 0.30, p = 0.001 and Std ß = - 0.25, p = 0.004). Comorbidities were associated inversely with social well-being (Std ß = - 0.27, p = .003). Comorbidities and treatment-related symptoms were not associated with PHQOL (p = 0.20-0.24). Sensitivity analyses suggested that psychological comorbidities, treatment-related psychological symptoms, and physical comorbidities were associated with social well-being, functional well-being, and MHQOL. CONCLUSIONS: Our study highlights the utility of risk-based survivorship care plans to address the negative, additive impact of comorbidities and the treatment-related symptoms to improve the health-related QOL among rural survivors. Future research should assess how contextual factors (e.g., geographic distance to oncologists and other providers) should be incorporated in survivorship care planning and implementation for rural survivors.

PURPOSE: Older adults with glaucoma show inappropriate gaze strategies during routine mobility tasks. Furthermore, glaucoma is a risk factor for falling and colliding with objects when walking. However, effective interventions to rectify these strategies and prevent these adverse events are scarce. We designed a gaze training program with the goal of providing proof-of-concept that we could modify mobility-related gaze behavior in this population. METHODS: A total of 13 individuals with moderate glaucoma participated in this study. We taught participants general and task-specific gaze strategies over two 1-hour sessions. To determine the efficacy of this gaze training program, participants performed walking tasks that required accurate foot placement onto targets and circumventing obstacles before and after training. We used a mobile eye tracker to quantify gaze and a motion-capture system to quantify body movement. RESULTS: After training, we found changes in the timing between gaze shifts away from targets relative to stepping on them (P < 0.05). In the obstacle negotiation task, we found a greater range of gaze shifts early in walking trials and changes in the timing between gaze shifts away from obstacles after training (P < 0.05), each suggesting better route planning. A posttraining reduction in foot-placement error and obstacle collisions accompanied these changes (P < 0.05). CONCLUSIONS: Our results demonstrated that it is possible to modify mobility-related gaze behavior and mobility performance in older adults with glaucoma. TRANSLATIONAL RELEVANCE: This study provides proof-of-concept for a gaze training program for glaucoma. A larger, randomized controlled trial is warranted.
RESUMEN
Objective: The purpose of this study was to carry out a systematic review of literature of effective reading intervention for students with - intellectual disabilities (ID), intellectual and developmental disabilities (IDD), and multiple disabilities (MD). Findings and recommendations for future research are discussed. Background and rationale: For students with ID, IDD, and MD ability to read can lead to a better quality of life and better integration into the mainstream society. Several studies have expressed a concern over more emphasis placed on social, personal, and vocational skills for individuals with ID, IDD, and MD than on reading and literacy learning. Having a repertoire of effective interventions carried out with this population will help teachers, teacher educators, and anyone else working with the individuals. Method: This study synthesized findings from previous research with 167 students with ID, IDD, and/or MD to assess effectiveness of instruction for key elements of effective reading instruction such as phonemic awareness, phonics, vocabulary, fluency, and comprehension. The review made it explicit that literature reviewed conforms to standards and quality indicators for experimental and quasi-experimental studies. Outcomes: The 12 studies identified and included in this review collectively provided evidence-based strategies for developing components of effective reading at elementary grades and sustaining effective reading at secondary levels. Four tables included describe details of participants, setting, strategies, and evidence of effectiveness. Implications for future research: Recommendations offered included carrying out more studies using qualitative and/or mixed-method approaches to further study use of these strategies in different classrooms and at different grade levels. An exclusive and systematic review of studies that used technology and assistive technology to teach reading could also be carried out.
RESUMEN
People must decide where, when, and for how long to allocate gaze to perform different motor behaviours. However, the factors guiding gaze during these ongoing, natural behaviours are poorly understood. Gaze shifts help acquire information, suggesting that people should direct gaze to locations where environmental details most relevant to the task are uncertain. To explore this, human subjects stepped on a series of targets as they walked. We used different levels of target uncertainty, and through instruction, altered the importance of (or subjective value assigned to) foot-placement accuracy. Gaze time on targets increased with greater target uncertainty when precise foot placement was more important, and these longer gaze times associated with reduced foot-placement error. Gaze times as well as the gaze shifts to and from targets relative to stepping differed depending on the target's position in the sequence and uncertainty level. Overall, we show that gaze is allocated to reduce uncertainty about target locations, and this depends on the value of this information gain for successful task performance. Furthermore, we show that the spatial-temporal pattern of gaze to resolve uncertainty changes with the evolution of the motor behaviour, indicating a flexible strategy to plan and control movement.

Odontogenic tumors comprise an unusual group of lesions of the jaw and present diverse histological patterns. Derived from the primordial tooth-forming tissues, they represent a heterogeneous group of lesions that range from hamartomas to benign and malignant neoplasms of variable aggressiveness. Sporadic case reports and diverse complex histogenetic source also defy categorization of odontogenic tumors. Many can be diagnosed accurately based on the distinctive clinical, radiological and histopathological presentation. Considerable variations in the clinicopathological presentation of odontogenic tumors can be confusing, increasing the chance of misdiagnosis. An interesting case of adenoid ameloblastoma reported in a 55-year-old male patient in the mandible, presenting with a diverse and intriguing histopathology, is discussed here.
