Evaluating Nurses' Time to Response by Severity and Cancer Stage in a Remote Symptom Monitoring Program for Patients With Breast Cancer.

PURPOSE: Remote symptom monitoring (RSM) using electronic patient-reported outcomes enables patients with cancer to communicate symptoms between in-person visits. A better understanding of key RSM implementation outcomes is crucial to optimize efficiency and guide implementation efforts. This analysis evaluated the association between the severity of patient-reported symptom alerts and time to response by the health care team. METHODS: This secondary analysis included women with stage I-IV breast cancer who received care at a large academic medical center in the Southeastern United States (October 2020-September 2022). Symptom surveys with at least one severe symptom alert were categorized as severe. Response time was categorized as optimal if the alert was closed by a health care team member within 48 hours. Odds ratios (ORs), predicted probabilities, and 95% CIs were estimated using a patient-nested logistic regression model. RESULTS: Of 178 patients with breast cancer included in this analysis, 63% of patients identified as White and 85% of patients had a stage I-III or early-stage cancer. The median age at diagnosis was 55 years (IQR, 42-65). Of 1,087 surveys included, 36% reported at least one severe symptom alert and 77% had an optimal response time by the health care team. When compared with surveys that had no severe symptom alerts, surveys with at least one severe symptom alert had similar odds of having an optimal response time (OR, 0.97; 95% CI, 0.68 to 1.38). The results were similar when stratified by cancer stage. CONCLUSION: Response times to symptom alerts were similar for alerts with at least one severe symptom compared with alerts with no severe symptoms. This suggests that alert management is being incorporated into routine workflows and not prioritized based on disease or symptom alert severity.

NCCN Guidelines® Insights: Distress Management, Version 2.2023.

These NCCN Guidelines for Distress Management discuss the identification and treatment of psychosocial problems in patients with cancer. All patients experience some level of distress associated with a cancer diagnosis and the effects of the disease and its treatment regardless of the stage of disease. Clinically significant levels of distress occur in a subset of patients, and identification and treatment of distress are of utmost importance. The NCCN Distress Management Panel meets at least annually to review comments from reviewers within their institutions, examine relevant new data from publications and abstracts, and reevaluate and update their recommendations. These NCCN Guidelines Insights describe updates to the NCCN Distress Thermometer (DT) and Problem List, and to the treatment algorithms for patients with trauma- and stressor-related disorders.

Adaptation of Remote Symptom Monitoring Using Electronic Patient-Reported Outcomes for Implementation in Real-World Settings.

PURPOSE: Despite evidence of clinical benefits, widespread implementation of remote symptom monitoring has been limited. We describe a process of adapting a remote symptom monitoring intervention developed in a research setting to a real-world clinical setting at two cancer centers. METHODS: This formative evaluation assessed core components and adaptations to improve acceptability and fit of remote symptom monitoring using Stirman's Framework for Modifications and Adaptations. Implementation outcomes were evaluated in pilot studies at the two cancer centers testing technology (phase I) and workflow (phase II and III) using electronic health data; qualitative evaluation with semistructured interviews of clinical team members; and capture of field notes from clinical teams and administrators regarding barriers and recommended adaptations for future implementation. RESULTS: Core components of remote symptom monitoring included electronic delivery of surveys with actionable symptoms, patient education on the intervention, a system to monitor survey compliance in real time, the capacity to generate alerts, training nurses to manage alerts, and identification of personnel responsible for managing symptoms. In the pilot studies, while most patients completed > 50% of expected surveys, adaptations were identified to address barriers related to workflow challenges, patient and clinician access to technology, digital health literacy, survey fatigue, alert fatigue, and data visibility. CONCLUSION: Using an implementation science approach, we facilitated adaptation of remote symptom monitoring interventions from the research setting to clinical practice and identified key areas to promote effective uptake and sustainability.

Evaluating the implementation and impact of navigator-supported remote symptom monitoring and management: a protocol for a hybrid type 2 clinical trial.

BACKGROUND: Symptoms in patients with advanced cancer are often inadequately captured during encounters with the healthcare team. Emerging evidence demonstrates that weekly electronic home-based patient-reported symptom monitoring with automated alerts to clinicians reduces healthcare utilization, improves health-related quality of life, and lengthens survival. However, oncology practices have lagged in adopting remote symptom monitoring into routine practice, where specific patient populations may have unique barriers. One approach to overcoming barriers is utilizing resources from value-based payment models, such as patient navigators who are ideally positioned to assume a leadership role in remote symptom monitoring implementation. This implementation approach has not been tested in standard of care, and thus optimal implementation strategies are needed for large-scale roll-out. METHODS: This hybrid type 2 study design evaluates the implementation and effectiveness of remote symptom monitoring for all patients and for diverse populations in two Southern academic medical centers from 2021 to 2026. This study will utilize a pragmatic approach, evaluating real-world data collected during routine care for quantitative implementation and patient outcomes. The Consolidated Framework for Implementation Research (CFIR) will be used to conduct a qualitative evaluation at key time points to assess barriers and facilitators, implementation strategies, fidelity to implementation strategies, and perceived utility of these strategies. We will use a mixed-methods approach for data interpretation to finalize a formal implementation blueprint. DISCUSSION: This pragmatic evaluation of real-world implementation of remote symptom monitoring will generate a blueprint for future efforts to scale interventions across health systems with diverse patient populations within value-based healthcare models. TRIAL REGISTRATION: NCT04809740 ; date of registration 3/22/2021.

Examining the association among fear of COVID-19, psychological distress, and delays in cancer care.

BACKGROUND: Given the high risk of COVID-19 mortality, patients with cancer may be vulnerable to fear of COVID-19, adverse psychological outcomes, and health care delays. METHODS: This longitudinal study surveyed the pandemic's impact on patients with cancer (N= 1529) receiving Patient Advocate Foundation services during early and later pandemic. Generalized estimating equation with repeated measures was conducted to assess the effect of COVID-19 on psychological distress. Logistic regression with repeated measures was used to assess the effect of COVID-19 on any delays in accessing health care (e.g., specialty care doctors, laboratory, or diagnostic testing, etc.). RESULTS: Among 1199 respondents, 94% considered themselves high risk for COVID-19. Respondents with more fear of COVID-19 had a higher mean psychological distress score (10.21; 95% confidence intervals [CI] 9.38-11.03) compared to respondents with less fear (7.55; 95% CI 6.75-8.36). Additionally, 47% reported delaying care. Respondents with more fear of COVID-19 had higher percentages of delayed care than those with less (56; 95% CI 39%-72% vs. 44%; 95% CI 28%-61%). These relationships persisted throughout the pandemic. For respondents with a COVID-19 diagnosis in their household (n = 116), distress scores were similar despite higher delays in care (58% vs. 27%) than those without COVID-19. CONCLUSIONS: Fear of COVID-19 is linked to psychological distress and delays in care among patients with cancer. Furthermore, those who are personally impacted see exacerbated cancer care delays. Timely psychosocial support and health care coordination are critical to meet increased care needs of patients with cancer during the COVID-19 pandemic.

Witnesses and Victims Both: Healthcare Workers and Grief in the Time of COVID-19.

Heathcare Workers (HCWs) recognize their responsibility to support the bereaved loved ones of our patients, but we also must attend to our own professional and personal grief in the COVID-19 pandemic. COVID-19 grief is occurring in the setting of incomplete grief, disenfranchised grief, fractured US governmental leadership, and evidence of great mistrust, systemic racism, and social injustice. In the intensity and pervasiveness of COVID-19, HCW fears for themselves, their colleagues, and their own loved ones are often in conflict with professional commitments. Even at the dawn of promising national and global vaccination programs, significant HCW morbidity and mortality in COVID-19 has already become clear, will continue to grow, and these effects likely will last far into the future. Given the risks of complicated grief for HCWs in the setting of COVID-19 deaths, individual HCWs must put every effort into their own preparation for these deaths as well as into their own healthy grieving. Equally importantly, our healthcare systems have a primary responsibility both to prepare HCWs and to support them in their anticipatory and realized grief. Special attention must be paid to our HCW trainees, who may have not yet developed personal or professional grief management strategies and are coming into healthcare practice during a time of great disruption to both teaching and clinical care.

The Impact of Depression on Health Care Utilization in Patients with Cancer.

Background: Depression is common in the oncology patient population. Little data exist on the impact of depression on health care utilization. Objectives: We evaluated the prevalence of depression and the relationship between depression and health care utilization in patients with cancer. Design: This cross-sectional study utilized patient-reported outcome data from predominately Medicare beneficiaries with cancer. We examined the emergency department visits and inpatient admissions within 3 months from survey. The relationship between depression and hospital visits was assessed using generalized linear models. Results: Of 1038 patients included in the study, 13% had moderate to severe depression. In adjusted models, patients with moderate or severe depression trended toward increased risk of hospitalizations compared with patients without depression (risk ratio: 1.25, 95% confidence interval: 0.97-1.62). Conclusions: Clinically significant depression is not uncommon in cancer patients. Further research is needed evaluating the relationship between depression, health care utilization, and early psychiatric intervention in oncology.

Implementing a Clinic-Based Telehealth Support Service (FamilyStrong) for Family Caregivers of Individuals with Grade IV Brain Tumors.

Background: Nearly 3 million U.S. family caregivers support someone with cancer. However, oncology clinic-based service lines that proactively screen, assess, and support cancer caregivers are nearly nonexistent. Objective: To examine first-year experiences of a nurse-led clinic-based telehealth support service (FamilyStrong) for family caregivers of patients with recently diagnosed grade IV brain tumors. Methods: This is a retrospective evaluation of operational outcomes from initial implementation of the FamilyStrong Service, developed in partnership with Caregiver and Bereavement Support Services at the University of Alabama at Birmingham (UAB) and the UAB Center for Palliative and Supportive Care. From August 2018 to December 2019, 53 family caregivers were proactively identified and enrolled by a palliative care nurse, working approximately one day/week, who performed monthly caregiver distress thermometer screenings by phone and provided emotional, educational, problem-solving, and referral support. Results: Enrolled family caregivers were a mean age of 53.5 years and mostly female (62.3%), full- or part-time employed (67.9%), and the patient's spouse/partner (79.3%). Caregivers provided support 6.7 days/week for 11.2 hours/day. The palliative care nurse performed 235 distress screenings and provided support that included 68 documented instances of emotional, problem-solving, and educational support, 41 nurse-facilitated communications with the neuro-oncology team about patient issues, and 24 referrals to UAB and community services (e.g., counseling). The most common problems caregivers wanted assistance with included: managing their relative's health condition and symptoms (51%), coordinating care/services (21%), and planning for the future/advance care planning (17%). Discussion: The FamilyStrong Program is among the first "real world" oncology clinic-based formal support services for advance cancer family caregivers.

X-ray processing of a realistic ice mantle can explain the gas abundances in protoplanetary disks.

The Atacama Large Millimeter Array has allowed a detailed observation of molecules in protoplanetary disks, which can evolve toward solar systems like our own. While CO, [Formula: see text], HCO, and [Formula: see text] are often abundant species in the cold zones of the disk, [Formula: see text] or [Formula: see text] are only found in a few regions, and more-complex organic molecules are not observed. We simulate, experimentally, ice processing in disks under realistic conditions, that is, layered ices irradiated by soft X-rays. X-ray emission from young solar-type stars is thousands of times brighter than that of today's sun. The ice mantle is composed of a [Formula: see text]:[Formula: see text]:[Formula: see text] mixture, covered by a layer made of [Formula: see text] and CO. The photoproducts found desorbing from both ice layers to the gas phase during the irradiation converge with those detected in higher abundances in the gas phase of protoplanetary disks, providing important insights on the nonthermal processes that drive the chemistry in these objects.

The project ENABLE Cornerstone randomized pilot trial: Protocol for lay navigator-led early palliative care for African-American and rural advanced cancer family caregivers.

BACKGROUND: Patients newly-diagnosed with advanced cancer often rely on family caregivers to provide daily support to manage healthcare needs and maintain quality of life. Early telehealth palliative care has been shown to effectively provide an extra layer of support to family caregivers, however there has been little work with underserved populations, especially African-Americans and rural-dwellers. This is concerning given the lack of palliative care access for these underserved groups. STUDY DESIGN: Single-site, small-scale pilot randomized controlled trial (RCT) of Project ENABLE (Educate, Nurture, Advise, Before Life Ends) Cornerstone, a lay navigator-led, early palliative care coaching intervention for family caregivers of African-American and rural-dwelling patients with newly-diagnosed advanced cancer. Family caregivers are paired with a trained lay navigator overseen by specialist palliative care clinicians and receive a series of brief in-person and telehealth sessions focusing on stress management and coping, caregiving skills and organization, getting help, self-care, and preparing for the future/advance care planning. This pilot trial is assessing acceptability of the intervention, feasibility of recruitment and data collection procedures, and preliminary efficacy compared to usual care on caregiver and patient quality of life and mood over 24 weeks. CONCLUSION: Once acceptability and feasibility are determined and issues addressed, the ENABLE Cornerstone intervention for underserved family caregivers of persons with advanced cancer will be primed for a fully powered efficacy RCT. Given its use of lay navigators and telehealth delivery, the intervention is potentially highly scalable and capable of overcoming many of the geographic, human resource, and cultural obstacles to accessing early palliative care support.

Distress Management, Version 3.2019, NCCN Clinical Practice Guidelines in Oncology.

Distress is defined in the NCCN Guidelines for Distress Management as a multifactorial, unpleasant experience of a psychologic (ie, cognitive, behavioral, emotional), social, spiritual, and/or physical nature that may interfere with the ability to cope effectively with cancer, its physical symptoms, and its treatment. Early evaluation and screening for distress leads to early and timely management of psychologic distress, which in turn improves medical management. The panel for the Distress Management Guidelines recently added a new principles section including guidance on implementation of standards of psychosocial care for patients with cancer.

Looking Back, Moving Forward: A Retrospective Review of Care Trends in an Academic Palliative and Supportive Care Program from 2004 to 2016.

Objective: To examine a rural-serving HBPC program's 12-year experience and historical trends to inform future program direction and expansion. Background: There is limited information about longitudinal trends in mature hospital-based palliative care (HBPC) programs serving racially diverse rural populations. Methods: This is a retrospective cross-sectional study of operational and patient-reported outcomes from the University of Alabama at Birmingham (UAB) Center for Palliative and Supportive Care (CPSC) inpatient (n=11,786) and outpatient (n=315) databases from October 2004 to March 2016. Results: Inpatients were a mean age of 63.7 years, male (50.1%), white (62.3%), general medicine referred (19.5%), primarily for goals of care (84.4%); 47.1% had "do not resuscitate/do not intubate" status and 46.9% were transferred to the Palliative Care and Comfort Unit (PCCU) after consultation. Median time from admission to consultation was three days, median PCCU length of stay (LOS) was four days, and median hospital LOS was nine days. Increased emergency department and cardiology referrals were notable in later years. Outpatients' mean age was 53.02 years, 63.5% were female, 76.8% were white, and 75.6% had a cancer diagnosis. Fatigue, pain, and disturbed sleep were the most common symptoms at the time of the visit; 34.6% reported mild-to-moderate depressive symptoms. Of patients reporting pain (64.8%), one-third had 50% or less relief from pain treatment. Discussion: The CPSC, which serves a racially diverse rural population, has demonstrated robust growth. We are poised to scale and spread our lessons learned to underserved communities.

Lay Patient Navigators' Perspectives of Barriers, Facilitators and Training Needs in Initiating Advance Care Planning Conversations With Older Patients With Cancer.

CONTEXT: Respecting Choices is an evidence-based model of facilitating advance care planning (ACP) conversations between health-care professionals and patients. However, the effectiveness of whether lay patient navigators can successfully initiate Respecting Choices ACP conversations is unknown. As part of a large demonstration project (Patient Care Connect [PCC]), a cohort of lay patient navigators underwent Respecting Choices training and were tasked to initiate ACP conversations with Medicare beneficiaries diagnosed with cancer. OBJECTIVES: This article explores PCC lay navigators' perceived barriers and facilitators in initiating Respecting Choices ACP conversations with older patients with cancer in order to inform implementation enhancements to lay navigator-facilitated ACP. METHODS: Twenty-six lay navigators from 11 PCC cancer centers in 4 states (Alabama, George, Tennessee, and Florida) completed in-depth, one-on-one semistructured interviews between June 2015 and August 2015. Data were analyzed using a thematic analysis approach. RESULTS: This evaluation identifies 3 levels-patient, lay navigator, and organizational factors in addition to training needs that influence ACP implementation. Key facilitators included physician buy-in, patient readiness, and navigators' prior experience with end-of-life decision-making. Lay navigators' perceived challenges to initiating ACP conversations included timing of the conversation and social and personal taboos about discussing dying. CONCLUSION: Our results suggest that further training and health system support are needed for lay navigators playing a vital role in improving the implementation of ACP among older patients with cancer. The lived expertise of lay navigators along with flexible longitudinal relationships with patients and caregivers may uniquely position this workforce to promote ACP.

HER2 challenge contest: a detailed assessment of automated HER2 scoring algorithms in whole slide images of breast cancer tissues.

AIMS: Evaluating expression of the human epidermal growth factor receptor 2 (HER2) by visual examination of immunohistochemistry (IHC) on invasive breast cancer (BCa) is a key part of the diagnostic assessment of BCa due to its recognized importance as a predictive and prognostic marker in clinical practice. However, visual scoring of HER2 is subjective, and consequently prone to interobserver variability. Given the prognostic and therapeutic implications of HER2 scoring, a more objective method is required. In this paper, we report on a recent automated HER2 scoring contest, held in conjunction with the annual PathSoc meeting held in Nottingham in June 2016, aimed at systematically comparing and advancing the state-of-the-art artificial intelligence (AI)-based automated methods for HER2 scoring. METHODS AND RESULTS: The contest data set comprised digitized whole slide images (WSI) of sections from 86 cases of invasive breast carcinoma stained with both haematoxylin and eosin (H&E) and IHC for HER2. The contesting algorithms predicted scores of the IHC slides automatically for an unseen subset of the data set and the predicted scores were compared with the 'ground truth' (a consensus score from at least two experts). We also report on a simple 'Man versus Machine' contest for the scoring of HER2 and show that the automated methods could beat the pathology experts on this contest data set. CONCLUSIONS: This paper presents a benchmark for comparing the performance of automated algorithms for scoring of HER2. It also demonstrates the enormous potential of automated algorithms in assisting the pathologist with objective IHC scoring.

Implementation and Impact of Patient Lay Navigator-Led Advance Care Planning Conversations.

CONTEXT: Advance care planning (ACP) improves alignment between patient preferences for life-sustaining treatment and care received at end of life (EOL). OBJECTIVES: To evaluate implementation of lay navigator-led ACP. METHODS: A convergent, parallel mixed-methods design was used to evaluate implementation of navigator-led ACP across 12 cancer centers. Data collection included 1) electronic navigation records, 2) navigator surveys (n = 45), 3) claims-based patient outcomes (n = 820), and 4) semistructured navigator interviews (n = 26). Outcomes of interest included 1) the number of ACP conversations completed, 2) navigator self-efficacy, 3) patient resource utilization, hospice use, and chemotherapy at EOL, and 4) navigator-perceived barriers and facilitators to ACP. RESULTS: From June 1, 2014 to December 31, 2015, 50 navigators completed Respecting Choices® First Steps ACP Facilitator training. Navigators approached 18% of patients (1319/8704); 481 completed; 472 in process; 366 declined. Navigators were more likely to approach African American patients than Caucasian patients (20% vs. 14%, P < 0.001). Significant increases in ACP self-efficacy were observed after training. The mean score for feeling prepared to conduct ACP conversations increased from 5.6/10 to 7.5/10 (P < 0.001). In comparison with patients declining ACP participation (n = 171), decedents in their final 30 days of life who engaged in ACP (n = 437) had fewer hospitalizations (46% vs. 56%, P = 0.02). Key facilitators of successful implementation included physician buy-in, patient readiness, and prior ACP experience; barriers included space limitations, identifying the "right" time to start conversations, and personal discomfort discussing EOL. CONCLUSION: A navigator-led ACP program was feasible and may be associated with lower rates of resource utilization near EOL.

Patient-centered support in the survivorship care transition: Outcomes from the Patient-Owned Survivorship Care Plan Intervention.

BACKGROUND: To the authors' knowledge, few studies to date have evaluated the effects of survivorship care planning on the care transition process from specialty cancer care to self-management and primary care, patient experience, or health outcomes. The Patient-owned Survivorship Transition Care for Activated, Empowered survivors (POSTCARE) is a single coaching encounter based on the Chronic Care Model that uses motivational interviewing techniques to engage survivors of breast cancer. The current study examined the effects of the POSTCARE intervention on patient outcomes and care coordination. METHODS: A total of 79 survivors of American Joint Commision on Cancer TNM System stage 0 to IIIB breast cancer were randomized to POSTCARE (40 patients) or usual care (39 patients). Patient outcomes were assessed using the 36-Item Short Form Health Survey (SF-36), Social/Role Activities Limitations, Self-Efficacy for Managing Chronic Disease 6-Item Scale, the Patient Activation Measure-Short Form, and Patient Health Questionnaire depression scale at baseline and at 3-month follow-up. Care coordination was assessed using confirmed primary care physician visits and reported discussion of the survivorship care plan at the 3-month follow-up. Logistic and linear regression analyses were conducted to examine the effect of POSTCARE on selected outcomes. RESULTS: Participants in the intervention group versus those receiving usual care demonstrated significantly higher self-reported health (F-statistic (3,71), 3.63; P =.017) and lower social role limitations (F (3,70), 3.82; P =.014) and a trend toward greater self-efficacy (F (3,69), 2.51; P = .07). Three quality-of-life domains reached clinically meaningful improvement at the 3-month follow-up, including physical role (P =.0009), bodily pain (P =.03), and emotional role (P =.04). CONCLUSIONS: The POSTCARE intervention appeared to have a positive impact on patient outcomes and demonstrated promise as a strategy with which to improve survivors' experience, care coordination, and health outcomes.

A Pilot Feasibility Intervention to Increase Advance Care Planning among African Americans in the Deep South.

BACKGROUND: Despite growing efforts to facilitate advance care planning (ACP) to decrease health disparities in palliative care, low completion rates of advance directives (AD) have been consistently found among African Americans. OBJECTIVE: The objective was to examine the feasibility of a multicomponent ACP intervention program that integrates motivational interviewing, evidence-based ACP facilitation program (Respecting Choices(®)), and health-literacy adjusted AD. This pilot study aims to address the unique barriers to ACP engagement among African Americans in the Deep South. METHODS: The design was a mixed-method randomized controlled trial design. Analysis of covariance (ANCOVA) and thematic content analysis (TCA) were conducted to identify barriers and facilitators for ACP engagement and to assess feasibility, knowledge, and intention to complete an AD. Thirty community-dwelling African Americans (mean age M = 55.43, SD = 6.71, range = 47-73) were recruited from the Deep South and randomly assigned to receive intervention (n = 15) or educational material (n = 15) at a local university medical center. RESULTS: All participants (n = 30) reported high satisfaction (M = 4.81, SD = 0.44, max score = 5) and increased intent to complete an AD at postintervention. A significant increase in knowledge on AD from baseline to postintervention was observed in the intervention group-t(14) = -3.06, p = 0.01, d = 1.67); no significant change was found for control. Lack of information, mistrust of doctors, and avoidance of discussing death were primary barriers to ACP discussions. Facilitators include ACP education, decreased mistrust, and proactive initiation of ongoing ACP discussions. CONCLUSIONS: Feasibility data revealed successful implementation of a brief intervention to increase ACP engagement and willingness to complete an AD among southern African Americans.

Technology-Delivered Mental Health Interventions for People Living with HIV/AIDS (PLWHA): a Review of Recent Advances.

HIV/AIDS infection and psychiatric diagnoses are closely linked, with an estimated 50 % of HIV-infected individuals diagnosed with co-occurring mental health disorders. Mental health disorders have been shown to be associated with HIV acquisition as well as poor treatment outcomes for those infected with HIV. Therefore, behavioral interventions to improve HIV/AIDS health outcomes have included interventions addressing mental health co-morbidities, such as depression and anxiety, and the use of technology to facilitate such intervention is growing. The current review focuses on research published between January 2011 and April 2015, exploring technology-based interventions aimed to improve health outcomes among HIV/AIDS individuals with co-occurring mental health symptoms. Technologies identified in this review included telephone-delivered and computer-delivered interventions. Despite rapid advances in technology use in the medical professions, particularly in the area of psychiatric treatment, little has been translated into the area of mental health research in the context of HIV disease. This review reveals that the widespread dissemination of various technologies, especially technologies facilitating access to care among vulnerable and marginalized populations, may be a necessary way to offer evidence-based mental health interventions to HIV/AIDS populations in need.

Automated image based prominent nucleoli detection.

INTRODUCTION: Nucleolar changes in cancer cells are one of the cytologic features important to the tumor pathologist in cancer assessments of tissue biopsies. However, inter-observer variability and the manual approach to this work hamper the accuracy of the assessment by pathologists. In this paper, we propose a computational method for prominent nucleoli pattern detection. MATERIALS AND METHODS: Thirty-five hematoxylin and eosin stained images were acquired from prostate cancer, breast cancer, renal clear cell cancer and renal papillary cell cancer tissues. Prostate cancer images were used for the development of a computer-based automated prominent nucleoli pattern detector built on a cascade farm. An ensemble of approximately 1000 cascades was constructed by permuting different combinations of classifiers such as support vector machines, eXclusive component analysis, boosting, and logistic regression. The output of cascades was then combined using the RankBoost algorithm. The output of our prominent nucleoli pattern detector is a ranked set of detected image patches of patterns of prominent nucleoli. RESULTS: The mean number of detected prominent nucleoli patterns in the top 100 ranked detected objects was 58 in the prostate cancer dataset, 68 in the breast cancer dataset, 86 in the renal clear cell cancer dataset, and 76 in the renal papillary cell cancer dataset. The proposed cascade farm performs twice as good as the use of a single cascade proposed in the seminal paper by Viola and Jones. For comparison, a naive algorithm that randomly chooses a pixel as a nucleoli pattern would detect five correct patterns in the first 100 ranked objects. CONCLUSIONS: Detection of sparse nucleoli patterns in a large background of highly variable tissue patterns is a difficult challenge our method has overcome. This study developed an accurate prominent nucleoli pattern detector with the potential to be used in the clinical settings.

Rewards and unique challenges faced by African-American custodial grandmothers: the importance of future planning.

OBJECTIVES: This exploratory study examined the context and consequences of custodial grandparenting, along with attitudes and preferences regarding future planning among 22 African-American custodial grandmothers. METHOD: A mixed-method research design was employed. Based on our integration of two theories regarding future planning and health behavior change, caregiving, emotional distress, religiosity and spirituality, and future planning were assessed using questionnaires along with semi-structured interviews. RESULTS: African-American custodial grandmothers (mean age M = 53.64, SD = 9.58) perceived their caregiving role as rewarding (72%) yet challenging (86%). More than 40% reported significant emotional distress (CES-D ≥ 16) that warrants clinical attention. Findings showed that while 64% of study participants had future plans regarding who will substitute in their caregiving role if they become incapacitated, only 9% had completed a living will. Three major themes emerged regarding custodial grandmothers' caregiving role which includes: (1) rewards; (2) challenges including feeling overwhelmed and health concerns; and (3) caregiving decisions including conflicts between 'My plan was…/put self on-hold' for grandchildren and difficulty with future planning. These themes highlighted the dynamics of caregiving across time, including current context and the ongoing process of decision-making. CONCLUSION: Findings suggest that while African-American custodial grandmothers find caregiving rewarding, they face unique challenges in contemplating and developing future plans. Custodial grandmothers think about substitute caregivers for their grandchildren but need assistance communicating a plan focused on their own needs for future care. Culturally sensitive interventions designed to facilitate effective utilization of future plans within this caregiver population are needed.
