Promoting childbirth in a rural health facility: A quasi-experimental study in western Kenya.

BACKGROUND: The high maternal and neonatal mortality rate in sub-Saharan Africa could be reduced by using navigation by means of mobile devices to increase the number of women who choose to give birth in a health center (HC) with a skilled healthcare practitioner. METHODS: A quasi-experimental design was used to test a midwife-delivered navigation by means of mobile phone. A total of 208 women were randomized to two groups (intervention and control). Women in the intervention group received up to three navigation calls from midwives. Women in the control group received usual antenatal education during prenatal visits. Data were collected using semistructured questionnaires. Childbirth location was determined through medical records. RESULTS: Overall, 180 (87%) women gave birth in a HC with a 3% advantage for the intervention group. A total of 86% (88/102) of the control group gave birth in a HC versus 89% (92/103) for the intervention group (Χ2 = 0.44, p-value = 0.51), with an unadjusted odds ratio of 1.33 (95% CI: 0.57, 3.09). Among those with personal phones, 91% (138/152) had a birth in a HC versus 79% (42/53) in those without a personal phone (Χ2 = 4.89, p-value = 0.03). CONCLUSIONS: The results of this study indicate that it is feasible to deliver phone-based navigation to support birth in a HC; personal phone ownership may be a factor in the success of this strategy.

Citrus-Gene interaction and melanoma risk in the UK Biobank.

High citrus consumption may increase melanoma risk; however, little is known about the biological mechanisms of this association, or whether it is modified by genetic variants. We conducted a genome-wide analysis of gene-citrus consumption interactions on melanoma risk among 1563 melanoma cases and 193 296 controls from the UK Biobank. Both the 2-degrees-of-freedom (df) joint test of genetic main effect and gene-environment (G-E) interaction and the standard 1-df G-E interaction test were performed. Three index SNPs (lowest P-value SNP among highly correlated variants [r2 > .6]) were identified from among the 365 genome-wide significant 2-df test results (rs183783391 on chromosome 3 [MITF], rs869329 on chromosome 9 [MTAP] and rs11446223 on chromosome 16 [DEF8]). Although all three were statistically significant for the 2-df test (4.25e-08, 1.98e-10 and 4.93e-13, respectively), none showed evidence of interaction according to the 1-df test (P = .73, .24 and .12, respectively). Eight nonindex, 2-df test significant SNPs on chromosome 16 were significant (P < .05) according to the 1-df test, providing evidence of citrus-gene interaction. Seven of these SNPs were mapped to AFG3L1P (rs199600347, rs111822773, rs113178244, rs3803683, rs73283867, rs78800020, rs73283871), and one SNP was mapped to GAS8 (rs74583214). We identified several genetic loci that may elucidate the association between citrus consumption and melanoma risk. Further studies are needed to confirm these findings.

Citrus Consumption and Risk of Non-Melanoma Skin Cancer in the UK Biobank.

Background: Non-melanoma skin cancer (NMSC) incidence has been dramatically increasing worldwide. Psoralen, a known photocarcinogen, is naturally abundant in citrus products, leading to the hypothesis that high citrus consumption may increase NMSC risk.Methods: We fitted age- and multivariable-adjusted logistic regression models to evaluate the association between citrus consumption and NMSC risk among 197,372 UKBB participants. A total of 9,613 NMSC cases were identified using International Classification of Disease 10 codes. Citrus consumption data were collected via five rounds of 24-hour recall questionnaires.Results: We found no association between high total citrus consumption and NMSC risk, although a slightly elevated NMSC risk was observed among participants who consumed >0 to half a serving of total citrus per day (OR [95% CI] = 1.08 [1.01-1.16]). There was no association between individual citrus products and NMSC risk.Conclusion: High citrus consumption was not associated with an increased risk of NMSC in our UKBB sample. Further studies are needed to clarify these associations.Supplemental data for this article is available online at https://doi.org/10.1080/01635581.2021.1952439 .

Comorbidity, cognitive dysfunction, physical functioning, and quality of life in older breast cancer survivors.

PURPOSE: Older breast cancer survivors (BCS) may be at greater risk for cognitive dysfunction and other comorbidities; both of which may be associated with physical and emotional well-being. This study will seek to understand these relationships by examining the association between objective and subjective cognitive dysfunction and physical functioning and quality of life (QoL) and moderated by comorbidities in older BCS. METHODS: A secondary data analysis was conducted on data from 335 BCS (stages I-IIIA) who were ≥ 60 years of age, received chemotherapy, and were 3-8 years post-diagnosis. BCS completed a one-time questionnaire and neuropsychological tests of learning, delayed recall, attention, working memory, and verbal fluency. Descriptive statistics and separate linear regression analyses testing the relationship of each cognitive assessment on physical functioning and QoL controlling for comorbidities were conducted. RESULTS: BCS were on average 69.79 (SD = 3.34) years old and 5.95 (SD = 1.48) years post-diagnosis. Most were stage II (67.7%) at diagnosis, White (93.4%), had at least some college education (51.6%), and reported on average 3 (SD = 1.81) comorbidities. All 6 physical functioning models were significant (p < .001), with more comorbidities and worse subjective attention identified as significantly related to decreased physical functioning. One model found worse subjective attention was related to poorer QoL (p < .001). Objective cognitive function measures were not significantly related to physical functioning or QoL. CONCLUSIONS: A greater number of comorbidities and poorer subjective attention were related to poorer outcomes and should be integrated into research seeking to determine predictors of physical functioning and QoL in breast cancer survivors.

Acceptance and commitment therapy for patient fatigue interference and caregiver burden in advanced gastrointestinal cancer: Results of a pilot randomized trial.

BACKGROUND: Fatigue often interferes with functioning in patients with advanced cancer, resulting in increased family caregiver burden. Acceptance and commitment therapy, a promising intervention for cancer-related suffering, has rarely been applied to dyads coping with advanced cancer. AIM: To examine the feasibility, acceptability, and preliminary efficacy of acceptance and commitment therapy for patient-caregiver dyads coping with advanced gastrointestinal cancer. Primary outcomes were patient fatigue interference and caregiver burden. DESIGN: In this pilot trial, dyads were randomized to six weekly sessions of telephone-delivered acceptance and commitment therapy or education/support, an attention control. Outcomes were assessed at baseline and at 2 weeks and 3 months post-intervention. SETTING/PARTICIPANTS: Forty patients with stage III-IV gastrointestinal cancer and fatigue interference and family caregivers with burden or distress were recruited from two oncology clinics and randomized. RESULTS: The eligibility screening rate (54%) and retention rate (81% at 2 weeks post-intervention) demonstrated feasibility. At 2 weeks post-intervention, acceptance and commitment therapy participants reported high intervention helpfulness (mean = 4.25/5.00). Group differences in outcomes were not statistically significant. However, when examining within-group change, acceptance and commitment therapy patients showed moderate decline in fatigue interference at both follow-ups, whereas education/support patients did not show improvement at either follow-up. Acceptance and commitment therapy caregivers showed medium decline in burden at 2 weeks that was not sustained at 3 months, whereas education/support caregivers showed little change in burden. CONCLUSIONS: Acceptance and commitment therapy showed strong feasibility, acceptability, and promise and warrants further testing. TRIAL REGISTRATION: ClinicalTrials.gov NCT04010227.

Process Evaluation of a Mailed Interactive Educational DVD in a Comparative Effectiveness Trial to Promote Colorectal Cancer Screening.

A process evaluation was conducted as part of a comparative effectiveness trial of a mailed interactive educational DVD intervention to promote colorectal cancer screening among average-risk patients who did not attend a scheduled colonoscopy. Participants (n = 371) for the trial were randomized to (1) mailed DVD, (2) mailed DVD plus patient navigation, or (3) usual care. Participants (n = 243) randomized to the two DVD intervention arms were called 2 weeks after mailing materials to complete a process evaluation interview about the DVD (September 2017-February 2020). Forty-nine (20%) participants were not reached, and 194 (80%) participants watched the DVD and completed the interview. The process evaluation assessed whether (1) the DVD content was helpful, (2) any new information was learned by participants, (3) the appropriate amount of information was included in the DVD, (4) participants were engaged when watching the DVD, (5) the DVD content was relevant, (6) participants were satisfied with the DVD (7) participants would recommend the DVD to others, and (8) their opinion about colorectal cancer screening was changed by watching the DVD. Among participants who watched the DVD, 99% reported the screening information was very or somewhat helpful, 47% learned new information, 75% said the DVD included the right amount of information, they were engaged (M = 3.35 out of 4, SD = 0.49), 87% reported all or most information applied to them, they were satisfied (M = 3.42 out of 4, SD = 0.39) with DVD content, 99% would recommend the DVD to others, and 45% reported changing their opinion about screening. To understand the effects of interventions being tested in trials and to plan the dissemination of evidence-based interventions, process evaluation is critical to assess the dose received and acceptability of behavioral interventions.

The impact of fear of cancer recurrence on healthcare utilization among long-term breast cancer survivors recruited through ECOG-ACRIN trials.

OBJECTIVE: To examine the relationship between fear of cancer recurrence (FCR) and healthcare utilization among long-term breast cancer survivors (BCS). METHODS: In a cross-sectional survey study, 505 younger survivors (YS: ≤45 years) and 622 older survivors (OS: 55-70 years) 3-8 years from diagnosis completed a questionnaire assessing demographics, medical history, FCR, and healthcare utilization. Healthcare utilization consisted of breast cancer (BC) and non-BC-related routine and nonroutine utilization. RESULTS: YS had significantly higher FCR than OS (p < 0.01). Independent of age, FCR was significantly associated with all three types of BC-related utilization (p < 0.05). In the multivariate models, we found a significant, positive interaction effect between FCR and increased comorbidities on nonroutine BC appointments (p = 0.01) and BC-related emergency room visits (p = 0.03). Additionally, comorbidities were associated with non-BC-related utilization (p < 0.01), and nonwhites were more likely to utilize nonroutine resources, both BC and non-BC-related (p < 0.01). CONCLUSIONS: Increased FCR has been associated with hypervigilance among survivors and may lead to increased healthcare utilization. YS are at higher risk for increased FCR and psychosocial concerns, which may lead to overutilization. Providers should be aware that higher FCR may be related to increased use of healthcare resources and that these patients might be better served with supportive resources to increase quality of life and decrease inappropriate utilization. While this study provides increased evidence of the relationship between FCR and healthcare utilization, interventions are needed for survivors at risk to address unmet needs, especially as life expectancy increases among BCS.

The mediating role of avoidant coping in the relationships between physical, psychological, and social wellbeing and distress in breast cancer survivors.

OBJECTIVE: Many breast cancer survivors (BCSs) recover from the negative sequelae of cancer treatment. However, some report persistent and disruptive distress well into disease-free survivorship. More information is needed on the predictors of distress in this growing population of BCS, including the role of avoidant coping, or attempts to avoid thoughts, feelings, and reminders of cancer, in mediating the relationship between distress and psychological, physical, and social domains of well-being. METHODS: In a large cross-sectional study, BCS (n = 1,127), who were 3 to 8 years post-diagnosis, completed a survey assessing demographic characteristics, medical history, distress (anxiety and depressive symptoms), avoidant coping, and physical (fatigue), psychological (fear of recurrence, attention, body image), and social (social support from a partner, social constraints from a partner) well-being. Multiple mediation analyses were conducted to determine if avoidant coping mediated the relationship between each distress variable (anxiety and depressive symptoms) and each well-being (fear of recurrence, attention, body image, fatigue, social support, and social constraints) variable. RESULTS: In all six mediation models, avoidant coping significantly (p < 0.001) mediated the relationship between each well-being variable (fear of recurrence, attention, body image, fatigue, social support, and social constraints) and each distress indicator (depression and anxiety). Avoidant coping mediated 19%-54% of the effects of the contributing factors on the distress variables. CONCLUSIONS: Avoidant coping may indicate risk for, or presence of, distress among BCS. Interventions to reduce distress may benefit from addressing avoidant coping styles.

Computer-tailored intervention increases colorectal cancer screening among low-income African Americans in primary care: Results of a randomized trial.

INTRODUCTION: Although African Americans have the highest colorectal cancer (CRC) incidence and mortality rates of any racial group, their screening rates remain low. STUDY DESIGN/PURPOSE: This randomized controlled trial compared efficacy of two clinic-based interventions for increasing CRC screening among African American primary care patients. METHODS: African American patients from 11 clinics who were not current with CRC screening were randomized to receive a computer-tailored intervention (n = 335) or a non-tailored brochure (n = 358) designed to promote adherence to CRC screening. Interventions were delivered in clinic immediately prior to a provider visit. Univariate and multivariable logistic regression models analyzed predictors of screening test completion. Moderators and mediators were determined using multivariable linear and logistic regression analyses. RESULTS: Significant effects of the computer-tailored intervention were observed for completion of a stool blood test (SBT) and completion of any CRC screening test (SBT or colonoscopy). The colonoscopy screening rate was higher among those receiving the computer-tailored intervention group compared to the nontailored brochure but the difference was not significant. Predictors of SBT completion were: receipt of the computer-tailored intervention; being seen at a Veterans Affairs Medical Center clinic; baseline stage of adoption; and reason for visit. Mediators of intervention effects were changes in perceived SBT barriers, changes in perceived colonoscopy benefits, changes in CRC knowledge, and patient-provider discussion. Moderators of intervention effects were age, employment, and family/friend recommendation of screening. CONCLUSION: This one-time computer-tailored intervention significantly improved CRC screening rates among low-income African American patients. This finding was largely driven by increasing SBT but the impact of the intervention on colonoscopy screening was strong. Implementation of a CRC screening quality improvement program in the VA site that included provision of stool blood test kits and follow-up likely contributed to the strong intervention effect observed at that site. The trial is registered at ClinicalTrials.gov as NCT00672828.

Acceptance and commitment therapy for breast cancer survivors with fear of cancer recurrence: A 3-arm pilot randomized controlled trial.

BACKGROUND: Fear of cancer recurrence (FCR) has a profound negative impact on quality of life (QOL) for many cancer survivors. Breast cancer survivors (BCS) are particularly vulnerable, with up to 70% reporting clinically significant FCR. To the authors' knowledge, evidence-based interventions for managing FCR are limited. Acceptance and commitment therapy (ACT) promotes psychological flexibility in managing life's stressors. The current study examined the feasibility and preliminary efficacy of group-based ACT for FCR in BCS. METHODS: Post-treatment BCS (91 patients with stage I-III disease) with clinical FCR randomly were assigned to ACT (6 weekly 2-hour group sessions), survivorship education (SE; 6 weekly 2-hour group sessions), or enhanced usual care (EUC; one 30-minute group coaching session with survivorship readings). FCR severity (primary outcome) and avoidant coping, anxiety, post-traumatic stress, depression, QOL, and other FCR-related variables (secondary outcomes) were assessed at baseline (T1), after the intervention (T2), 1 month after the intervention (T3), and 6 months after the intervention (T4) using intent-to-treat analysis. RESULTS: Satisfactory recruitment (43.8%) and retention (94.5%) rates demonstrated feasibility. Although each arm demonstrated within-group reductions in FCR severity over time, only ACT produced significant reductions at each time point compared with baseline, with between-group differences at T4 substantially favoring ACT over SE (Cohen d for effect sizes, 0.80; P < .001) and EUC (Cohen d, 0.61; P < .01). For 10 of 12 secondary outcomes, only ACT produced significant within-group reductions across all time points. By T4, significant moderate to large between-group comparisons favored ACT over SE and EUC with regard to avoidant coping, anxiety, depression, QOL, and FCR-related psychological distress. CONCLUSIONS: Group-based ACT is a feasible and promising treatment for FCR and associated outcomes in BCS that warrants testing in larger, fully powered trials.

Associations of metabolic syndrome and C-reactive protein with mortality from total cancer, obesity-linked cancers and breast cancer among women in NHANES III.

Although metabolic syndrome (MetS) is a prognostic factor for cancer occurrence, the association of MetS and cancer mortality remains unclear. The purpose of this study was to evaluate whether MetS, components of MetS and C-reactive protein (CRP) are associated with cancer mortality in women. A total of 400 cancer deaths, with 140 deaths from obesity-linked-cancers (OLCas), [breast (BCa), colorectal, pancreatic and endometrial], linked through the National Death Index, were identified from 10,104 eligible subjects aged ≥18 years. Cox proportional hazards regression was used to estimate multivariable-adjusted hazard ratios (HR) for cancer mortality. MetS was associated with increased deaths for total cancer [HR = 1.33, 95% confidence interval (CI) 1.04-1.70] and BCa [HR = 2.1, 95% CI, 1.09-4.11]. The risk of total cancer [HR = 1.7, 95% CI, 1.12-2.68], OLCas [HR = 2.1, 95% CI, 1.00-4.37] and BCa [HR = 3.8, 95% CI, 1.34-10.91] mortality was highest for women with all MetS components abnormal, compared to those without MetS. Linear associations of blood-pressure [HR = 2.5, 1.02-6.12, Quartile (Q) 4 vs Q1, p trend = 0.004] and blood-glucose [HR = 2.2, 1.04-4.60, Q4 vs. Q1, p trend = 0.04] with total-OLCas mortality were observed. A threefold increased risk of BCa mortality was observed for women with enlarged waist circumference, ≥100.9 cm, [HR = 3.5, 1.14-10.51, p trend = 0.008] and in those with increased blood glucose, ≥101 mg/dL, [HR = 3.2, 1.11-9.20, p trend = 0.03] compared to those in Q1. None of the components of MetS were associated with total-cancer mortality. CRP was not associated with cancer mortality. In conclusion, MetS is associated with total-cancer and breast-cancer mortality, with waist circumference, blood pressure and blood glucose as independent predictors of OLCas and BCa mortality.

Acceptance and commitment therapy for symptom interference in metastatic breast cancer patients: a pilot randomized trial.

PURPOSE: Breast cancer is the leading cause of cancer mortality in women worldwide. With medical advances, metastatic breast cancer (MBC) patients often live for years with many symptoms that interfere with activities. However, there is a paucity of efficacious interventions to address symptom-related suffering and functional interference. Thus, this study examined the feasibility and preliminary efficacy of telephone-based acceptance and commitment therapy (ACT) for symptom interference with functioning in MBC patients. METHODS: Symptomatic MBC patients (N = 47) were randomly assigned to six telephone sessions of ACT or six telephone sessions of education/support. Patients completed measures of symptom interference and measures assessing the severity of pain, fatigue, sleep disturbance, depressive symptoms, and anxiety. RESULTS: The eligibility screening rate (64%) and high retention (83% at 8 weeks post-baseline) demonstrated feasibility. When examining within-group change, ACT participants showed decreases in symptom interference (i.e., fatigue interference and sleep-related impairment; Cohen's d range = - 0.23 to - 0.31) at 8 and 12 weeks post-baseline, whereas education/support participants showed minimal change in these outcomes (d range = - 0.03 to 0.07). Additionally, at 12 weeks post-baseline, ACT participants showed moderate decreases in fatigue and sleep disturbance (both ds = - 0.43), whereas education/support participants showed small decreases in these outcomes (ds = - 0.24 and - 0.18 for fatigue and sleep disturbance, respectively). Both the ACT and education/support groups showed reductions in depressive symptoms (ds = - 0.27 and - 0.28) at 12 weeks post-baseline. Group differences in all outcomes were not statistically significant. CONCLUSIONS: ACT shows feasibility and promise in improving fatigue and sleep-related outcomes in MBC patients and warrants further investigation.

Examining the effect of peer helping in a coping skills intervention: a randomized controlled trial for advanced gastrointestinal cancer patients and their family caregivers.

PURPOSE: At the end of life, spiritual well-being is a central aspect of quality of life for many patients and their family caregivers. A prevalent spiritual value in advanced cancer patients is the need to actively give. To address this need, the current randomized trial examined whether adding a peer helping component to a coping skills intervention leads to improved meaning in life and peace for advanced gastrointestinal cancer patients and their caregivers. Feasibility and acceptability outcomes were also assessed. METHODS: Advanced gastrointestinal cancer patients and caregivers (n = 50 dyads) were randomly assigned to a 5-session, telephone-based coping skills intervention or a peer helping + coping skills intervention. One or both dyad members had moderate-severe distress. Peer helping involved contributing to handouts on coping skills for other families coping with cancer. Patients and caregivers completed measures of meaning in life/peace, fatigue, psychological symptoms, coping self-efficacy, and emotional support. Patient pain and caregiver burden were also assessed. RESULTS: Small effects in favor of the coping skills group were found regarding meaning in life/peace at 1 and 5 weeks post-intervention. Other outcomes did not vary as a function of group assignment, with both groups showing small decreases in patient and caregiver fatigue and caregiver distress and burden. High recruitment and retention rates supported feasibility, and high participant satisfaction ratings supported acceptability. CONCLUSIONS: Although a telephone-based intervention is feasible and acceptable for this population, peer helping in the context of a coping skills intervention does not enhance spiritual well-being relative to coping skills alone.

Spirituality, emotional distress, and post-traumatic growth in breast cancer survivors and their partners: an actor-partner interdependence modeling approach.

BACKGROUND: The association between spirituality and emotional health has been well documented in healthy individuals. A small literature has shown that spirituality plays a role in well-being for some breast cancer (BC) survivors; however, this link is virtually unexplored in partners/spouses of survivors. The current study aimed to assess the relationship between spirituality, emotional distress, and post-traumatic growth for BC survivors and their partners using a dyadic analyses approach. METHODS: A total of 498 couples who were 3-8 years post-BC diagnosis were recruited from the Eastern Oncology Group database. RESULTS: For BC survivors and their partners, greater levels of spirituality were associated with increases in their own post-traumatic growth. There was no relation between BC and partner spirituality and their own emotional distress, but partner's spirituality was associated with reduced occurrence of intrusive thoughts in the BC survivor. In contrast, BC survivors' spirituality was found to be wholly unrelated to partner's mental health and adjustment. CONCLUSIONS: Following diagnosis and treatment, spirituality appears to associate with positive growth in BC survivors and their partners. However, BC survivor and partner spirituality seem to be ineffective at impacting the other's post-traumatic growth or emotional distress, with the exception of intrusive thoughts. Dyadic analysis takes into account the reciprocal influence of close relationships on health and is an important and under-utilized methodology in behavioral oncology research and clinical practice.

Long-term fear of recurrence in young breast cancer survivors and partners.

BACKGROUND: Fear of a breast cancer recurrence is the most prevalent and disruptive source of distress for long-term survivors and their partners. However, few studies have focused on predictors of fear of recurrence. The aim of this study is to test the efficacy of the Social Cognitive Processing Theory (SCPT) in predicting fear of recurrence in long-term breast cancer survivors diagnosed at age 45 years or younger and their partners. METHODS: In a large cross-sectional study, breast cancer survivors (n = 222) 3-8 years from diagnosis and their partners completed a survey assessing demographic characteristics, fear of recurrence, social constraints, and cognitive processing (intrusive thoughts and cognitive avoidance). Mediation analyses were conducted for survivors and partners separately to determine if cognitive processing would mediate the relationship between social constraints and fear of recurrence. RESULTS: Cognitive processing mediated the relationship between social constraints and fear of recurrence both for survivors [F(3,213) = 47.541, R2 = 0.401, p < 0.001] and partners [F(3,215) = 27.917, R2 = 0.280, p < 0.001). Demographic variables were not significant predictors of fear of recurrence. CONCLUSIONS: As predicted, cognitive processing mediated the relationship between social constraints and fear of recurrence. Results expand the utility of the SCPT in long-term survivors and their partners by supporting its use in intervention design. Copyright © 2015 John Wiley & Sons, Ltd.

Avoidant coping and self-efficacy mediate relationships between perceived social constraints and symptoms among long-term breast cancer survivors.

OBJECTIVE: Many breast cancer survivors feel constrained in discussing their cancer experience with others. Limited evidence suggests that social constraints (e.g., avoidance and criticism) from loved ones may negatively impact breast cancer survivors' global health, but research has yet to examine relationships between social constraints and common physical symptoms. Informed by social cognitive processing theory, this study examined whether perceived social constraints from partners and healthcare providers (HCPs) were associated with fatigue, sleep disturbance, and attentional functioning among long-term breast cancer survivors (N = 1052). In addition, avoidant coping and self-efficacy for symptom management were examined as potential mediators of these relationships. METHODS: Long-term breast cancer survivors (mean years since diagnosis = 6) completed questionnaires assessing social constraints from partners and HCPs, avoidant coping, self-efficacy for symptom management, and symptoms (i.e., fatigue, sleep disturbance, and attentional functioning). Structural equation modeling was used to evaluate the hypothesized relationships among variables in two models: one focused on social constraints from partners and one focused on social constraints from HCPs. RESULTS: Both models demonstrated good fit. Consistent with theory and prior research, greater social constraints from both partners and HCPs were associated with greater symptom burden (i.e., greater fatigue and sleep disturbance, poorer attentional functioning). In addition, all relationships were mediated by avoidant coping and self-efficacy for symptom management. CONCLUSIONS: Findings are consistent with social cognitive processing theory and suggest that symptom management interventions may be enhanced by addressing the impact of social constraints from survivors' partners and HCPs on their coping and self-efficacy.

Changes in Adult BMI and Waist Circumference Are Associated with Increased Risk of Advanced Colorectal Neoplasia.

BACKGROUND: Waist circumference (WC) is a stronger predictor of colon cancer (CRC) risk than body mass index (BMI). However, how well change in either WC or BMI predicts risk of advanced colorectal neoplasia (AN) is unclear. AIMS: To determine the relationship between change in BMI and WC from early adulthood to later age and the risk of AN and which change measure is a stronger predictor. METHODS: In 4500 adults, ages 50-80, with no previous neoplasia and undergoing screening colonoscopy, BMI and WC at age 21 and at time of screening were reported. Changes in BMI and WC were defined using universal risk cutoffs. Known CRC risk factors were controlled in the logistic models. RESULTS: Overall, model statistics showed WC change (omnibus test χ 2 = 10.15, 2 DF, p value = 0.006) was a statistically stronger predictor of AN than BMI change (omnibus test χ 2 = 5.66, 5 DF, p value = 0.34). Independent of BMI change, participants who increased WC (OR 1.44; 95% CI 1.05-1.96) or maintained a high-risk WC (OR 2.50; 95% CI 1.38-4.53) at age 21 and at screening had an increased risk of AN compared to those with a low-risk WC. Study participants who were obese at age 21 and at screening had an increased risk of AN (OR 1.87; 95% CI 1.08-3.23) compared to those who maintained a healthy BMI. Maintaining an overweight BMI or increasing BMI was not associated with AN. CONCLUSIONS: Maintaining an unhealthy BMI and WC throughout adult life may increase risk of AN. WC change may be a better predictor of AN than BMI change.

Mammography Adherence in African-American Women: Results of a Randomized Controlled Trial.

BACKGROUND: Breast cancer is the second leading cause of cancer mortality among women in the developed world. Mammography screening is especially important for African-Americans because they experience a greater mortality (OR = 1.38) than Caucasians despite having a lower incidence of breast cancer. PURPOSE: The purpose of this study was to compare the effects of two interventions with usual care on mammography adherence among African-American women. METHODS: A subsample of African-American women (n = 244) aged 41-65 years who had not had a mammogram in the last 15 months and no history of breast cancer was randomly assigned to receive (1) mailed interactive DVD, (2) computer-tailored telephone counseling, or (3) usual care. RESULTS: The DVD intervention was five times more effective than usual care for promoting mammography screening at 6 months follow-up among women who earned less than $30,000 (OR = 5.3). Compared to usual care, neither the DVD nor phone produced significant effects for women with household incomes >$30,000. CONCLUSION: Use of a mailed DVD for low-income African-American women may be an effective way to increase mammography adherence.

Evaluating the impact of chemotherapy-induced peripheral neuropathy symptoms (CIPN-sx) on perceived ability to work in breast cancer survivors during the first year post-treatment.

PURPOSE: To describe the impact of chemotherapy-induced peripheral neuropathy symptoms (CIPN-sx) on breast cancer survivors' (BCS) perceived ability to work post-treatment. METHODS: The sample included 22 chemotherapy-treated (Ctx+) and 22 chemotherapy-naïve (Ctx-) female BCS. Data was collected at the following three time points: baseline (post-surgery, pre-chemotherapy), 1 month (1 M) post-chemotherapy, and approximately 1 year (1 Y) later. The presence, frequency, number, and severity of CIPN-sx were self-reported using the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity questionnaire (FACT/GOG-Ntx) version 4, a validated 11-item CIPN measure. Perceived ability to work was measured using an item from the Functional Well-Being subscale of the FACT/GOG-Ntx. RESULTS: At 1 Y, more than 50 % of Ctx+ reported discomfort, numbness, or tingling in their hands or feet; weakness; or difficulty feeling small objects. The presence, number, and severity of these symptoms were correlated with being less able to work for Ctx+ at 1 M but not 1 Y. Results of a regression analysis using CIPN-sx to predict work ability found that models combining (1) hand numbness and trouble feeling small objects, (2) trouble buttoning buttons and trouble feeling small objects, (3) foot numbness and foot pain, (4) foot numbness and trouble walking, and (5) trouble hearing and hand pain each predicted survivors who were "not at all" able to work at 1 M. CONCLUSIONS: Unresolved CIPN-sx may play a role in challenges working for BCS post-treatment. These findings highlight the need for research to explore the impact that CIPN-sx have on BCS' ability to work, as well as the development of interventions to improve work function in BCS with CIPN-sx.

Family caregiving challenges in advanced colorectal cancer: patient and caregiver perspectives.

PURPOSE: Family caregivers of advanced colorectal cancer patients may be at increased risk for psychological distress. Yet their key challenges in coping with the patient's illness are not well understood. Soliciting both patient and caregiver perspectives on these challenges would broaden our understanding of the caregiving experience. Thus, the purpose of this research was to identify caregivers' key challenges in coping with their family member's advanced colorectal cancer from the perspective of patients and caregivers. METHODS: Individual, semi-structured qualitative interviews were conducted with 23 advanced colorectal cancer patients and 23 primary family caregivers. Interview data were analyzed via thematic analysis. RESULTS: In nearly all cases, patient and caregiver reports of the caregiver's key challenge were discrepant. Across patient and caregiver reports, caregivers' key challenges included processing emotions surrounding the patient's initial diagnosis or recurrence and addressing the patient's practical and emotional needs. Other challenges included coping with continual uncertainty regarding the patient's potential functional decline and prognosis and observing the patient suffer from various physical symptoms. CONCLUSIONS: Findings suggest that eliciting the perspectives of both patients and caregivers regarding caregivers' challenges provides a more comprehensive understanding of their experience. Results also point to the need to assist caregivers with the emotional and practical aspects of caregiving.
