Act or Wait? Presentation Delay in Symptomatic Breast Cancer in China.

BACKGROUND: In Western countries, factors contributing to breast cancer presentation delay have been identified, but little is known about presentation delay in China, where culture and healthcare systems are quite different. OBJECTIVE: To describe the delay interval among newly diagnosed breast cancer patients in China and to identify factors influencing delay, including the COVID-19 pandemic. METHODS: Using a cross-sectional design, we recruited 154 participants within 3 months of pathological diagnosis of breast cancer. Data were collected using standardized scales and open-ended questions. RESULTS: We found 44.8% of participants delayed ≥1 month, and 24.7% delayed ≥3 months before presentation, after self-discovery of symptoms. Logistic regression analysis showed that factors associated with longer delay (≥1 month) included preferring female physicians for breast examination, fewer negative emotions (afraid, anxious, distressed) regarding breast symptoms, more competing priorities, believing folk therapy can help treat lumps, and visiting a secondary or tertiary hospital instead of primary healthcare providers (P < .05 for all). Interaction tests showed perceived seriousness of symptoms significantly predicted delay of ≥1 month only when perceived healthcare access or trust in physicians was low. Patients (14%) reported delaying due to fear of COVID-19 infection and inability to leave home. CONCLUSIONS: Presentation delays were substantial and multilevel barriers to timely presentation were identified, which would be expected to contribute to later-stage cancer at diagnosis. IMPLICATIONS FOR PRACTICE: Findings suggest that nursing interventions and improved health policies are urgently needed in China, including breast cancer education to increase awareness.

Health Behavior Adherence in a Metropolitan-Based Metabolic Syndrome Management Program during the COVID-19 Pandemic.

Background: The COVID-19 pandemic increased the worldwide prevalence of metabolic syndrome. The purpose of this study was to assess health behavior adherence during the pandemic in adults who had engaged in a metabolic syndrome management program for at least 6 months. This assessment included an evaluation of health behavior changes, factors influencing adherence, and clinical parameters. The city-wide program was operated by the Seoul Metropolitan Government. Methods: Baseline and follow-up data were compared in 116 participants who engaged in the program for at least 6 months prior to the pandemic. Health behaviors and clinical parameters were examined. Generalized estimating equation analysis was used to identify sociodemographic variables influencing health behavior adherence over time. Results: Systolic blood pressure, waist circumference, and blood glucose improved (all P<0.05), and risk factors decreased (P<0.001) from baseline to follow-up (mean±standard deviation, 1.13±0.91 years). All six health behaviors, physical activity and weight control, eating habits, alcohol consumption and smoking, stress management, sleep and rest, and medication compliance and medical examination improved (all P<0.001) from baseline to follow-up (2.37±1.05 years). Smoking and employment negatively influenced adherence to health behaviors (P<0.05). Participants felt the most beneficial part of the program was receiving sequential medical examination results with follow-up consultations by public health professionals without charge. Conclusion: Our study demonstrated the durability of the impact of the Seoul Program on all six targeted health behaviors as well as clinical parameters. Findings encourage participation in such broad-based programs and development of novel approaches to facilitate success for smokers and employed participants.

Impact of genomic testing on urologists' treatment preference in favorable risk prostate cancer: A randomized trial.

INTRODUCTION: The Oncotype Dx Genomic Prostate Score (GPS) is a 17-gene relative expression assay that predicts adverse pathology at prostatectomy. We conducted a novel randomized controlled trial to assess the impact of GPS on urologist's treatment preference for favorable risk prostate cancer (PCa): active surveillance versus active treatment (i.e., prostatectomy/radiation). This is a secondary endpoint from the ENACT trial which recruited from three Chicago hospitals from 2016 to 2019. METHODS: Ten urologists along with men with very low to favorable-intermediate risk PCa were included in the study. Participants were randomly assigned to standardized counseling with or without GPS assay. The main outcome was urologists' preference for active treatment at Visit 2 by study arm (GPS versus Control). Multivariable best-fit binary logistic regressions were constructed to identify factors independently associated with urologists' treatment preference. RESULTS: Two hundred men (70% Black) were randomly assigned to either the Control (96) or GPS arm (104). At Visit 2, urologists' preference for prostatectomy/radiation almost doubled in the GPS arm to 29.3% (29) compared to 14.1% (13) in the Control arm (p = 0.01). Randomization to the GPS arm, intermediate NCCN risk level, and lower patient health literacy were predictors for urologists' preference for active treatment. DISCUSSION: Limitations included sample size and number of urologists. In this study, we found that GPS testing reduced urologists' likelihood to prefer active surveillance. CONCLUSIONS: These findings demonstrate how obtaining prognostic biomarkers that predict negative outcomes before treatment decision-making might influence urologists' preference for recommending aggressive therapy in men eligible for active surveillance.

Delayed Presentation, Diagnosis, and Treatment of Breast Cancer Among Chinese Women: An Integrative Literature Review.

BACKGROUND: Delays before treatment initiation increase the likelihood of later-stage diagnosis of breast cancer and reduce survival. Among Chinese women living in mainland China, Hong Kong, and Taiwan, the amount of time lost in delay and the factors influencing it are unclear. OBJECTIVE: This integrative review aimed to characterize delay intervals among Chinese women, identify factors contributing to delay, and develop a conceptual model of these factors. METHODS: Using Whittemore and Knafl's methodology for integrative reviews, PubMed, CINAHL, Web of Science, SCOPUS, PsycINFO, and China National Knowledge Infrastructure were searched for primary research articles. For 15 selected studies, quality evaluation was performed employing the Crowe Critical Appraisal Tool. A narrative synthesis was developed to summarize and explain the findings. RESULTS: Total delay intervals (from first discovery of breast symptoms to treatment initiation) exceeded 3 months for 50.2% to 52% of breast cancer patients. The greatest delay occurred between symptom discovery and first presentation (patient intervals). Factors affecting delay in presentation, diagnosis, and treatment included symptom appraisal, Chinese cultural factors, knowledge of breast cancer symptoms and screening, health history, personality, social and healthcare factors, and background factors. CONCLUSIONS: Half of Chinese breast cancer patients delayed long enough to lower their chances of survival. Our review sheds light on how the reviewed factors contribute to delay and their unique influences in this population. IMPLICATIONS FOR PRACTICE: Factors identified can inform nursing interventions that raise breast cancer awareness and promote timely diagnosis and treatment in Chinese women.

Effectiveness of an online support program to help female cancer patients manage their health and illness: Protocol for a randomized controlled trial.

Background: The aim of the trial is to evaluate the effectiveness of interventions provided by online support program apps, adopting health-related quality of life (HR-QOL) scores as indicators. Methods: The design is as an open, randomized, parallel-group trial with longitudinal data collection. The subjects will be female cancer patients receiving treatment in a Japanese National Cancer Hospital. Patients assigned to the experimental group will use three apps: an app for them to monitor their own health (monitoring app), an app to assess their understanding of their diagnosis and treatment and their readiness to receive treatment (confirmation app), and an app to address mental health issues (writing app); patients assigned to the control group will use only the monitoring app. At baseline (before patients undergo cancer treatment) and three other times during the study, evaluation indicators will be obtained from three different standardized HR-QOL scales that are incorporated in the monitoring app. The study hypothesis is that at 6 months after patients' baseline health monitoring, patients in the experimental group will have improved HR-QOL as compared with patients in the control group. Conclusion: This study is based on self-regulation theory, so it is important that the online support program works in an efficient way with respect to patients finding and setting their own health-related goals and adapting their behaviors to achieve those goals. Verifying the effectiveness of the combination of the three apps will show that it is a scientifically valid approach to maintaining or improving the HR-QOL of cancer patients.

Recruitment and Retention of Urban Pregnant Women to a Clinical Study Administering an Oral Isotope Dietary Tracer.

Introduction: Pregnant women are a vulnerable population that are difficult to engage in clinical research. We report successful recruitment and retention strategies used in a longitudinal pilot study of urban racially/ethnically diverse pregnant women that involved administration of an orally ingested isotope tracer, multiple venipunctures, biopsy of placenta after delivery, and cord or placental blood collection. Materials and Methods: We used direct strategies to recruit English-speaking obese and nonobese pregnant women aged 17-45 years, who were in the third trimester of pregnancy. The study required data collection at 32-34 and 34-36 gestational weeks and delivery. Strategies included frequent personal engagement with participants and staff to build relationships and trust, tangible appreciation, and the study team being present at delivery. In addition, leveraging hospital information technology (IT) services was critical to ensure retention through labor and delivery (LD). Results: A racially (52% Black, 23% White, and 10% other) and ethnically (15% Hispanic or Latinx) diverse sample of pregnant women was enrolled. Of the 52 women enrolled, 85% of women completed all procedures. Conclusions: This is the first report of successful strategies for recruitment and retention of racially/ethnically diverse pregnant women in a longitudinal study requiring oral administration of an isotope tracer. Personal engagement with multiple touch points, starting with recruitment and continuing regularly throughout the third trimester, was the most successful strategy. Creating and maintaining relationships with the LD providers and staff and utilizing hospital IT, including targeted electronic medical record alerts, ensured successful retention for the duration of the study. Trial Registration: Not applicable.

Health Insurance Status as a Predictor of Mode of Colon Cancer Detection but Not Stage at Diagnosis: Implications for Early Detection.

OBJECTIVE: For colon cancer patients, one goal of health insurance is to improve access to screening that leads to early detection, early-stage diagnosis, and polyp removal, all of which results in easier treatment and better outcomes. We examined associations among health insurance status, mode of detection (screen detection vs symptomatic presentation), and stage at diagnosis (early vs late) in a diverse sample of patients recently diagnosed with colon cancer from the Chicago metropolitan area. METHODS: Data came from the Colon Cancer Patterns of Care in Chicago study of racial and socioeconomic disparities in colon cancer screening, diagnosis, and care. We collected data from the medical records of non-Hispanic Black and non-Hispanic White patients aged ≥50 and diagnosed with colon cancer from October 2010 through January 2014 (N = 348). We used logistic regression with marginal standardization to model associations between health insurance status and study outcomes. RESULTS: After adjusting for age, race, sex, and socioeconomic status, being continuously insured 5 years before diagnosis and through diagnosis was associated with a 20 (95% CI, 8-33) percentage-point increase in prevalence of screen detection. Screen detection in turn was associated with a 15 (95% CI, 3-27) percentage-point increase in early-stage diagnosis; however, nearly half (47%; n = 54) of the 114 screen-detected patients were still diagnosed at late stage (stage 3 or 4). Health insurance status was not associated with earlier stage at diagnosis. CONCLUSIONS: For health insurance to effectively shift stage at diagnosis, stronger associations are needed between health insurance and screening-related detection; between screening-related detection and early stage at diagnosis; or both. Findings also highlight the need to better understand factors contributing to late-stage colon cancer diagnosis despite screen detection.

Quality of Life and Prolonged Symptoms in Korean Breast Cancer Survivors.

BACKGROUND: A culture of serious overwork in South Korea, more than other developed countries, may impact symptoms and quality of life (QOL) experienced by Korean breast cancer survivors (BCS). OBJECTIVES: The aim of this study was to examine health-related QOL and influencing factors in BCS in Seoul, Korea, who have recovered from treatment for at least 1 year and returned to normal life and work. METHODS: In a cross-sectional study, 199 BCS completed a self-administered questionnaire in Seoul, Korea. RESULTS: Mean QOL scores were lower than expected, with 49% of the variance explained by depressive symptoms, physical fatigability, cognitive impairment, and social support. Psychological distress was high (67.8%), along with anxiety (47.2%) and depressive symptoms (36.7%). Participants reported a high prevalence of physical fatigability (71.1%), sleeping an average of only 6 hours per night, with 58.9% reporting poor quality sleep. CONCLUSIONS: Quality of life was lower in Korean BCS than comparable studies in the United States, although participants received care at a premiere medical center. Depressive symptoms and anxiety were common and did not taper off over the 5 years after diagnosis, unlike BCS elsewhere. Korean survivors experienced significant physical fatigability, much higher than reported in a US study of mixed male and female cancer survivors. Overwork was not a significant predictor of QOL, although 30% of employed women reported working 45 to 90 hours weekly. IMPLICATIONS FOR PRACTICE: Findings demonstrate the importance of continued efforts to mitigate these symptoms in clinical survivorship care, as well as future research, to provide avenues for improving QOL for BCS, particularly in Korea.

Rural Cancer Disparities: Understanding Implications for Breast and Cervical Cancer Diagnoses.

BACKGROUND: Rural populations experience several disparities, influenced by structural-, community-, and individual-level barriers, across the breast and cervical cancer continuum. OBJECTIVES: This study seeks to identify structural-, community-, and individual-level barriers that affect rural populations across the cancer continuum, understand the role of nurses serving rural populations in breast and cervical cancer screening and diagnostics, and provide recommendations for working with rural patients. METHODS: This is a secondary analysis of qualitative interviews conducted with public health nurses serving rural populations. FINDINGS: Emergent themes indicate that rural populations experience barriers that affect disparities across the breast and cervical cancer continuum, including a changing healthcare landscape, access to cancer-focused care, access to insurance, collective poverty, and demographic factors. Nurses working with rural communities can address these disparities as they fulfill multiple roles and responsibilities.

Psychometric properties of the Korean version of the Pittsburgh Fatigability Scale in breast cancer survivors.

BACKGROUND: Fatigability has recently emerged in oncology as a concept that anchors patients' perceptions of fatigue to defined activities of specified duration and intensity. This study aimed to examine the psychometric properties of the Korean version of the Pittsburgh Fatigability Scale (K-PFS) for women with breast cancer. METHODS: This cross-sectional study involved 196 women with breast cancer recruited from a tertiary hospital in Seoul, Korea. Reliability was evaluated using Cronbach's alpha, and confirmatory factor analysis was conducted to examine the factor structure of the K-PFS. Four goodness-of-fit values were evaluated: (1) the comparative fit index (CFI), (2) the Tucker-Lewis index (TLI), (3) the root mean square error of approximation (RMSEA), and (4) the standardized root mean square residual (SRMR). RESULTS: Of the 196 survivors, 71.1% had greater physical fatigability (K-PFS Physical score ≥ 15) and 52.6% had greater mental fatigability (K-PFS Mental score ≥ 13). The Cronbach's alpha coefficient for the total K-PFS scale was 0.926, and the coefficients for the physical and mental fatigability domains were 0.870 and 0.864, respectively. In the confirmatory factor analysis for physical fatigability, the SRMR value (0.076) supported goodness of fit, but other model fit statistics did not (CFI = 0.888, TLI = 0.826, and RMSEA = 0.224). For mental fatigability, although three goodness-of-fit values were acceptable (CFI = 0.948, TLI = 0.919, and SRMR = 0.057), the RMSEA value (0.149) did not indicate good model fit. However, each item coefficient was statistically significant (> 0.5), and the K-PFS was therefore found to be valid from a theoretical perspective. CONCLUSION: This study provides meaningful information on the reliability and validity of the K-PFS instrument, which was developed to meet an important need in the context of breast cancer survivors. Additional research should examine its test-retest reliability and construct validity with performance measures.

Prepregnancy Obesity Does Not Impact Placental Iron Trafficking.

BACKGROUND: Iron is critical for fetal development. Neonates of obese women may be at risk for poor iron status at birth as a result of maternal inflammation-driven overexpression of hepcidin. OBJECTIVES: The objective of this study was to determine differences in placental transfer of oral iron (57Fe) and expression of placental transferrin receptor 1 (TFR1) and ferroportin (FPN) mRNA and protein and their association with maternal and neonatal iron-related parameters, including maternal hepcidin, among women with and without prepregnancy (PP) obesity. METHODS: 57Fe ingested during the third trimester of pregnancy was recovered in venous umbilical cord blood among 20 PP obese [BMI (in kg/m2): 30.5-43.9] and 22 nonobese (BMI: 18.5-29.0) women aged 17-39 y. Placental TFR1 and FPN mRNA and protein expression were quantified via qPCR and Western blot. Maternal and neonatal markers of iron status and regulation, as well as inflammation, were measured. Descriptive and inferential statistical tests (e.g., Student t test, Pearson correlation) were used for data analysis. RESULTS: There was no difference in cord blood enrichment of 57Fe or placental mRNA or protein expression of TFR1 or FPN among the women with and without PP obesity. Maternal hepcidin was not correlated with cord blood enrichment of 57Fe or placental FPN mRNA or protein expression. Maternal log ferritin (corrected for inflammation) was inversely correlated with log percent enrichment of 57Fe in cord blood (partial r = -0.50; P < 0.01, controlled for marital status) and protein expression of TFR1 (r = -0.43; P = 0.01). CONCLUSIONS: Placental iron trafficking did not differ among women with and without PP obesity. Findings reinforce the importance of maternal iron stores in regulating placental iron trafficking.

Impact of a Genomic Test on Treatment Decision in a Predominantly African American Population With Favorable-Risk Prostate Cancer: A Randomized Trial.

PURPOSE: The Genomic Prostate Score (GPS), performed on biopsy tissue, predicts adverse outcome in prostate cancer (PCa) and has shown promise for improving patient selection for active surveillance (AS). However, its impact on treatment choice in high-risk populations of African Americans is largely unknown and, in general, the effect of the GPS on this difficult decision has not been evaluated in randomized trials. METHODS: Two hundred men with National Comprehensive Cancer Network very low to low-intermediate PCa from three Chicago hospitals (70% Black, 16% college graduates) were randomly assigned at diagnosis to standard counseling with or without a 12-gene GPS assay. The primary end point was treatment choice at a second postdiagnosis visit. The proportion of patients choosing AS was compared, and multivariable modeling was used to estimate the effects of various factors on AS acceptance. RESULTS: AS acceptance was high overall, although marginally lower in the intervention group (77% v 88%; P = .067), and lower still when men with inadequate specimens were excluded (P = .029). Men with lower health literacy who received a GPS were seven-fold less likely to choose AS compared with controls, whereas no difference was seen in men with higher health literacy (Pinteraction = .022). Among men with low-intermediate risk, 69% had GPS values consistent with unfavorable intermediate or high-risk cancer. AS choice was also independently associated with a family history of PCa and having health insurance. CONCLUSION: In contrast to other studies, the net effect of the GPS was to move patients away from AS, primarily among men with low health literacy. These findings have implications for our understanding of how prognostic molecular assays that generate probabilities of poor outcome can affect treatment decisions in diverse clinical populations.

Advance Care Planning for African American Caregivers of Relatives With Dementias: Cluster Randomized Controlled Trial.

BACKGROUND AND OBJECTIVES: African-American family caregivers may have insufficient knowledge to make informed end-of-life (EOL) decisions for relatives with dementias. Advance Care Treatment Plan (ACT-Plan) is a community-based education intervention to enhance knowledge of dementia and associated EOL medical treatments, self-efficacy, intentions, and behavior (written EOL care plan). This study evaluated efficacy of the intervention compared to attention control. RESEARCH DESIGN AND METHODS: In a theoretically based, 2-group, cluster randomized controlled trial, 4 similar Midwestern urban megachurches were randomized to experimental or control conditions. Each church recruited African-American caregivers, enrolling concurrent waves of 5 to 9 participants in 4 weekly 1-hour sessions (358 total: ACT-Plan n = 173, control n = 185). Dementia, cardiopulmonary resuscitation (CPR), mechanical ventilation (MV), and tube feeding (TF) treatments were discussed in ACT-Plan classes. Participants completed assessments before the initial class, after the final class (week 4), and at week 20. Repeated measures models were used to test the intervention effect on changes in outcomes across time, adjusting for covariates as needed. RESULTS: Knowledge of CPR, MV, TF, and self-efficacy to make EOL treatment decisions increased significantly more in the ACT-Plan group at weeks 4 and 20. Knowledge of dementia also increased more in the ACT-Plan group at both points, reaching statistical significance only at week 20. Intentions to make EOL treatment decisions and actually an advance care plan were similar between treatment arms. DISCUSSION AND IMPLICATIONS: Findings demonstrate promise for ACT-Plan to increase informed EOL treatment decisions for African American caregivers of individuals with dementias.

Race and Gender Differences in Awareness of Colorectal Cancer Screening Tests and Guidelines Among Recently Diagnosed Colon Cancer Patients in an Urban Setting.

The purpose of this study was to first characterize the prevalence of recall, recognition, and knowledge of colon cancer screening tests and guidelines (collectively, "awareness") among non-Hispanic black (NHB) and NH white (NHW) urban colon cancer patients. Second, we sought to examine whether awareness was associated with mode of cancer detection. Low awareness regarding colon cancer screening tests and guidelines may explain low screening rates and high prevalence of symptomatic detection. We examined recall, recognition, and knowledge of colorectal cancer (CRC) screening tests and guidelines and their associations with mode of cancer detection (symptomatic versus screen-detected) in 374 newly diagnosed NHB and NHW patients aged 45-79. Patients were asked to name or describe any test to screen for colon cancer (recall); next, they were given descriptions of stool testing and colonoscopy and asked if they recognized each test (recognition). Lastly, patients were asked if they knew the screening guidelines (knowledge). Overall, awareness of CRC screening guidelines was low; just 20% and 13% of patients knew colonoscopy and fecal test guidelines, respectively. Awareness of CRC screening tests and guidelines was especially low among NHB males, socioeconomically disadvantaged individuals, and those diagnosed at public healthcare facilities. Inability to name or recall a single test was associated with reduced screen-detected cancer compared with recall of at least one test (36% vs. 22%, p = 0.01). Low awareness of CRC screening tests is a risk factor for symptomatic detection of colon cancer.

Comparing the roles of social context, networks, and perceived social functioning with health-related quality of life among self-reported rural female cancer survivors.

PURPOSE: Rural women, compared to urban, experience worse survivorship outcomes, including poorer health-related quality of life (QOL). There is a need to characterize the role of multilevel social factors that contribute to QOL, including context, networks, and functioning. Our objectives were to (1) use latent class analysis to identify distinct classes of social context and social networks and (2) examine how multilevel social factors (context, networks, and functioning) are associated with health-related QOL. METHODS: We recruited self-identified rural survivors to the Illinois Rural Cancer Assessment (2017-2018), via community-based sampling methods, and participants completed the survey online, by phone, or on paper. We used latent class analysis to generate multidimensional variables for contextual and network factors. We next modeled each social factor sas a predictor in separate, bivariable linear regressions for the QOL outcomes, followed by multivariable, adjusted regressions. RESULTS: For our first objective, there were three classes each of county-level contexts (1, highly rural, socioeconomically disadvantaged, and mostly lacking in cancer-related services; 2, mostly rural, moderately disadvantaged, and underserved; 3, mostly metropolitan, less disadvantaged, and most-resourced) and social networks (1, no caregivers; 2, only spousal caregivers with whom they communicated daily; 3, multiple caregivers with varying daily communication). For our second objective, among all social factors, only functioning was associated with better mental health-related QOL. No factors were associated with physical health-related QOL. CONCLUSIONS: Our findings suggest a rich diversity of social context and networks among rural female cancer survivors, and social functioning is particularly important for mental health-related QOL.

Assessing the relationship between patient-provider communication quality and quality of life among rural cancer survivors.

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.

Prepregnancy Obesity Is Not Associated with Iron Utilization during the Third Trimester.

BACKGROUND: An adequate maternal iron supply is crucial for maternal red blood cell (RBC) expansion, placental and fetal growth, and fetal brain development. Obese women may be at risk for poor iron status in pregnancy due to proinflammatory-driven overexpression of hepcidin leading to decreased iron bioavailability. OBJECTIVE: The objective of this study was to determine the impact of prepregnancy (PP) obesity on third-trimester maternal iron utilization. DESIGN: Using the stable isotope 57Fe, we measured iron utilization in the third trimester in PP obese [BMI (in kg/m2): ≥30] and nonobese (BMI: 18.5-29.9) women. We also assessed iron status, hepcidin, inflammation, erythropoietin, dietary iron intake, and gestational weight gain. Descriptive and inferential statistical tests (e.g., Student t test, Pearson correlation) were used for data analysis. RESULTS: Fifty pregnant women (21 PP obese, 29 PP nonobese) were included. Mean age was 27.6 ± 6.8 y and mean gestational age at time of 57Fe administration was 32.7 ± 0.7 wk. Anemia (hemoglobin <11 g/dL for non-black and <10.2 g/dL for black women) affected 38% of women (43% PP obese compared with 35% PP nonobese; P = 0.55). Women with PP obesity had significantly higher C-reactive protein (8.5 compared with 3.4 mg/L, P = 0.0007) and total body iron corrected for inflammation (6.0 compared with 4.3 mg/kg, P = 0.04) compared with the nonobese women. There was no difference in serum hepcidin or iron utilization between the PP BMI groups. CONCLUSION: This is the first study to assess the impact of PP obesity on maternal iron utilization. We found no difference in iron utilization in the third trimester of pregnancy in women with and without PP obesity. Despite higher frequency of anemia, women with PP obesity had less depleted body iron stores, suggesting some degree of iron sequestration. This finding should be followed up and extended to understand effects on fetal iron bioavailability.

Gender- and Race-Based Differences in Barriers and Facilitators to Early Detection of Colon Cancer.

Background: Early detection of colon cancer is essential to successful treatment and survival, yet most patients are diagnosed only after onset of symptoms. Previous studies suggest differences in colon cancer screening and presentation by gender and race, but reasons for this are not understood. The purpose of this study was to identify barriers and facilitators to early detection of colon cancer and to compare by gender and race. Materials and Methods: In the Colon Cancer Patterns of Care in Chicago study, non-Hispanic Black and White (NHB, NHW) patients aged 30-79 newly diagnosed with colon cancer between 2010 and 2014 (n = 249) underwent in-depth semistructured interviews regarding the pathway to colon cancer diagnosis. Mixed qualitative and quantitative methods were used to analyze patient narratives and to compare response patterns by gender and race within prespecified domains: health care access factors, provider-related factors, patient-related factors, and diagnostic workup factors. Results: Women reported more barriers than facilitators to early detection than men (barrier: facilitator ratio of 0.60 vs. 0.48). Thematic differences were seen, with women reporting more barriers related to health care access, scheduling of follow-ups, symptom recognition, and inappropriate or inconclusive diagnostic tests. Fewer women than men reported facilitators related to provider factors such as ease of scheduling follow-ups and receiving referrals for screening or a specialist. NHBs and NHWs reported similar ratios of barriers to facilitators (0.55 vs. 0.53), but more NHBs than NHWs reported barriers related to health care access, scheduling follow-ups, and clinical delays, and fewer NHBs reported facilitators related to health care accessibility (existing relationship with provider, ease of scheduling follow-ups). Conclusions: In this diverse population of patients recently diagnosed with colon cancer, we identified substantive gender- and race-based differences in the types and burden of barriers and facilitators to early detection experienced in the path to diagnosis. These differences should be explored further as they may contribute to disparities in the diagnosis and prognosis of colon cancer.

Reliability and validity of the Japanese version of the Quality of Life Index for patients with cancer.

This study was designed to evaluate the psychometric properties of the newly completed Japanese translation of the Ferrans and Powers Quality of Life Index Cancer Version III (QLI). Using a cross-sectional descriptive design, 136 ambulatory patients with gastrointestinal cancer (55 receiving chemotherapy, 76 with stable health status after treatment, and five status not known) completed a questionnaire at a one-time point, and 26 patients (stable health status) completed the questionnaire again 2 weeks later. Internal consistency reliability was supported by Cronbach's α of .96 for the total scale, with subscales ranging from .83 to .93. A test-retest correlation of 0.76 (total scale) provided evidence of stability reliability over a 2-week period, with subscale retest correlations ranging from 0.70 to 0.83. Confirmatory factor analysis showed the same four domains for the Japanese translation as the original QLI, supporting construct validity. We also assessed construct validity by examining the relationships between the Japanese QLI and six other concepts known to be related to the quality of life. As hypothesized, all correlations were moderate and in the expected direction (pain -0.39, anxiety -0.54, depression -0.63, stress -0.51, pain interfering with functioning -0.52, and general health 0.62). This evidence of the reliability and validity of the Japanese translation of the QLI supports its use in research and clinical practice to evaluate the impact of cancer and treatment. This new translation can be used to assess the patient's perspective of their quality of life, both within Japan and in cross-cultural studies with the QLI in other languages.
