Inequitable access to surveillance colonoscopy among Medicare beneficiaries with surgically resected colorectal cancer.

BACKGROUND: After colorectal cancer (CRC) surgery, surveillance with colonoscopy is an important step for the early detection of local recurrence. Unfortunately, surveillance colonoscopy is underused, especially among racial/ethnic minorities. This study assesses the association between patient and neighborhood factors and receipt of surveillance colonoscopy. METHODS: This retrospective, population-based cohort study used Surveillance, Epidemiology, and End Results-Medicare linked data (2009-2014). Beneficiaries with surgically resected stage II or III CRC between the ages of 66 and 85 years were identified, and multivariable logistic regression was used to assess the effect of factors on receipt of colonoscopy. RESULTS: Overall, 57.5% of the patients received initial surveillance colonoscopy. After adjustments for all factors, Blacks and Hispanics had lower odds of receiving colonoscopy than non-Hispanic Whites (NHWs; 29.6% for Blacks; P = .002; 12.9% for Hispanics; P > .05). NHWs with Medicaid coverage had 35% lower odds of surveillance colonoscopy than NHWs without Medicaid coverage. Minority patients with Medicaid were more likely to receive colonoscopy than their racial/ethnic counterparts without Medicaid coverage (P > .05). Hispanics residing in neighborhoods with incomes of ≥$90,000 had significantly lower odds of surveillance colonoscopy than Hispanics residing in neighborhoods with incomes of $0 to $30,000. CONCLUSIONS: Receipt of initial surveillance colonoscopy remains low, and there are acute disparities between Black and NHW patients. The association between factors that assess a patient's ability to access colonoscopy and actual receipt of colonoscopy suggests inequitable access to surveillance colonoscopy within and across racial/ethnic groups.

The interdisciplinary and psychosocial gap in cancer survivorship: A longitudinal study in a Latin American Cancer Center.

BACKGROUND AND OBJECTIVES: There is lack of information on the quality of care provided to the rapidly increasing population of cancer survivors in Latin America. Our study attempts to address this gap and to identify areas needed to be improved. METHODS: A random sample of 210 breast and colorectal cancer survivors were selected from a hospital-based registry in Chile. Cancer registry information, electronic chart review, and personal interviews were used to assess medical and nonmedical care over a 5-year period. Survivorship care practices were compared to a standardized reference based on the US Institute of Medicine domains and the American Cancer Association guidelines. RESULTS: Over 80% of breast and colorectal cancer survivors received appropriate medical care, ongoing testing surveillance and risk factors assessment. Only a third of survivors were assessed for psychosocial disorders and 25% of them received interdisciplinary care. Overall, 66.1% of breast and 58.6% of colorectal cancer survivors reached the expected quality level of cancer survivorship care according to the reference standard (p < .001). CONCLUSION: Medical care practices reached a high standard in a leading cancer center in Latin America. However, a much stronger psychosocial assessment and interdisciplinary care is needed to improve survivorship cancer quality care.

Eat Healthy, Be Active Community Workshops implemented with rural Hispanic women.

BACKGROUND: In the U.S., obesity disproportionately affects some racial/ethnic groups more than others; 42.5% of Hispanic adults are obese, compared to 32.6% of non-Hispanic whites (NHW). Research also shows that Mexican American women are 40% more likely to be overweight, as compared to NHW women. With high obesity rates among Hispanics, improving healthier lifestyle practices is an important step for reducing health disparities. The Eat Healthy, Be Active (EHBA) community workshops were developed to assist individuals in translating national nutrition and physical activity recommendations into action. Promotora-led EHBA workshops could be used to promote obesity-related health behavior lifestyle changes among Hispanics. METHODS: Hispanic women from rural communities in Washington state were recruited to participate in a six-week Promotora-led workshop series. This pilot study used a pre- and post-test study design to examine differences in healthy lifestyle knowledge and practices. RESULTS: A total of 49 Hispanic women participated in the workshops, of whom 45% were obese. Six-weeks after implementation of EHBA, women had improvements in healthy lifestyle practices, including an increase in nutrition label literacy, decrease in consumption of food eaten in restaurants, and an increase in the number of times a woman performed physical activity long enough to make them sweat. CONCLUSION: The findings from this pilot study indicate that delivering EHBA workshops through promotoras is a feasible culturally relevant approach to promoting healthier lifestyle practices among Hispanic women. Further, focusing on females, who do the food shopping and preparation in their homes, may help increase awareness among whole families.

Implementation of an integrated framework for a breast cancer screening and navigation program for women from underresourced communities.

BACKGROUND: Trends in breast cancer mortality in the United States are decreasing, but racial disparities persist. Using an implementation science framework to inform evidence-based breast cancer screening and navigation within federally qualified health centers (FQHCs) with community stakeholders can mitigate barriers to screening. METHODS: Using an integrated theoretical framework of the Practical, Robust Implementation and Sustainability Model and the Social Ecological Model, the University of Illinois Cancer Center and Mile Square Health Centers (MSHC) FQHC developed a breast cancer screening and navigation program, known as the Mile Square Accessible Mammogram Outreach and Engagement (Mi-MAMO) program, to tackle breast cancer disparities in Chicago among underresourced communities. To increase access to screening, patient navigators conducted community outreach activities. Partnerships were forged with community-based organizations, health care systems, and insurers. Outcomes were monitored with standardized performance measures. RESULTS: Between January and December 2017, 103 women received a screening mammogram at MSHC. To increase screening rates, Mi-MAMO was started in August 2017. Between January and December 2018, the number of women who received a screening mammogram increased to 567. From August 2017 to December 2018, 779 women received navigation to screening and/or diagnostic services through the Mi-MAMO program. The majority of women were uninsured (63.9%), and 95.5% were racial/ethnic minorities. Twenty-four percent (n = 185) completed diagnostic services, and 10 women received positive breast cancer diagnoses (mean age, 49.7 years); all successfully navigated to treatment. The Mi-MAMO program is ongoing. CONCLUSIONS: Deploying an integrated framework for patient navigation programs can increase breast cancer screening utilization and awareness among underresourced populations at higher risk for breast cancer.

Understanding a Diverse Cancer Center Catchment Area: A Qualitative Needs Assessment Built on a Theoretical Framework.

INTRODUCTION: Quantitative approaches to the cancer incidence and mortality of a geographic region may lack understanding of the human context in the region thereby affecting how relevant cancer prevention and control activities can best be targeted to a cancer center's catchment area. OBJECTIVES: The objective of this study was to obtain and analyze qualitative data that described the barriers and facilitators in a cancer center's catchment area. A further objective was to use the assessment to plan a comprehensive approach to cancer prevention and control activities in the region. METHODS: Extensive qualitative data were gathered from 32 key informants in the 13 county catchment area. We used the Warnecke Model for Analysis of Population Health and Health Disparities to analyze the qualitative data. We coded factors affecting cancer prevention and control using a directed content analysis approach guided by the Warnecke Model. RESULTS: Four outcome types included fundamental barriers such as political environment and discrimination, gaps in resources, and lack of coordinated activities. Social and physical barriers included distrust, diverse language and cultures, and geographic distance. Individual barriers included lack of system negotiation, health literacy, and poverty. Biological barriers were disparate disease rates in specific groups. CONCLUSION: The analysis and assessment led to the creation of a catchment area wide coalition that used the results to formulate a comprehensive strategic plan to address the barriers in the region.

Moving closer to death: understanding psychosocial distress among older veterans with advanced cancers.

BACKGROUND: Early identification of psychosocial distress is important to address the needs of vulnerable populations and influence symptom management. Older veterans diagnosed with life-limiting cancers are particularly vulnerable because they often have unmet needs, experiencing psychological or emotional problems and gaps in healthcare communication, which extends suffering. Lack of emotional support, ongoing physical pain, and unresolved symptom control can further increase distress among older veterans, contributing to complexity of decision-making for end of life (EOL) care. OBJECTIVE: We explored older veterans' experiences and identification of psychosocial distress in cancer care to better understand how they describe distress while facing the end of life. METHODS: Guiding this study is a conceptual framework from psychosocial oncology with the multifactorial experience of distress indicated by NCCN guidelines for distress screening. We use a phenomenological approach to explore the experience of psychosocial distress among older veterans diagnosed with advanced cancers at risk for dying within a year. INCLUSION CRITERIA: Provider response of "no" to, "Would you be surprised if your patient died within a year?" and "yes", to the question, "Have you talked with your patient about the severity of their illness as being life-limiting, terminal?" RESULTS: Five themes emerged: (1) the meaning of distress: "It's hard to explain"; (2) severity of advanced cancer: "There's no stage five"; (3) distressing thoughts about the possibility of dying: "Either way, it's life limiting"; (4) coping: "Deal with it and hope for a better day"; and (5) personal factors: "I don't want to be anything but a man who can handle adversity." Findings suggest older veterans may have unique cancer experiences different from other populations. CONCLUSION: Older veterans in this study exhibited distressing symptoms which demonstrate they are at risk for declining health and in need of support for their distress. Healthcare providers are urged to understand the complexity of distress to provide the best possible treatment for older veterans.

Role of Family Obligation Stress on Ugandan Women's Participation in Preventive Breast Health.

BACKGROUND: The purpose of this study is to determine the role of family obligation stress on Ugandan women's participation in preventive breast health through the receipt of breast cancer education and health check-ups. MATERIALS AND METHODS: A validated survey was conducted on a community sample of Ugandan women, providing a multi-item scale to assess preventive breast-health-seeking behaviors and measure family obligation stress (FO; range 6-18). Univariate and multivariate linear regression was used to assess associations between sociodemographic factors and FO. Univariate and multivariate linear regression (used in conjunction with the robust sandwich estimator for standard errors) and probability differences (PDs) were used to evaluate associations between preventive breast-health-seeking behaviors, sociodemographic factors, and FO. RESULTS: A total of 401 Ugandan women ages 25-74 participated in the survey. Most had three or more children in the home (60%) and were employed full time (69%). Higher FO was associated with increasing number of children and/or adults in the household (p < .05), full-time employment (p < .001), and being single (p = .003). Women with higher FO were less likely to participate in breast cancer education (PD = -0.02 per 1-point increase, p = .008) and preventive health check-ups (PD = -0.02, p = .018), associations that persisted on multivariate analysis controlling for sociodemographic factors. CONCLUSION: Ugandan women with high FO are less likely to participate in preventive breast cancer detection efforts including breast cancer education and preventive health check-ups. Special efforts should be made to reach women with elevated FO, because it may be a risk factor for late-stage presentation among women who develop breast cancer. IMPLICATIONS FOR PRACTICE: High family obligation stress (FO) significantly reduces women's participation in preventive health check-ups and breast cancer education. These findings support research in U.S. Latinas showing high FO negatively affects women's health, suggesting that FO is an important factor in women's health-seeking behavior in other cultures. Addressing family obligation stress by including family members involved in decision-making is essential for improving breast cancer outcomes in low- and middle-income countries, such as Uganda.

Educating Latinas about cervical cancer and HPV: a pilot randomized study.

INTRODUCTION: The purpose of this study was to assess effects of three different educational intervention arms on knowledge of and intention to receive Pap testing and HPV co-testing. METHODS: Three active educational intervention arms were developed: a fotonovela, a radionovela, and a digital story. A pilot randomized controlled trial of 160 Latinas was conducted to assess the effectiveness of the intervention arms in increasing knowledge of cervical cancer and HPV and intention to be screened for cervical cancer compared to an attention control group (flu vaccination). RESULTS: Women in all three treatment arms significantly increased knowledge about cervical cancer compared to control arm (p = 0.02). Knowledge about cervical cancer screening also increased in the active arms compared to control (p = 0.0003). Knowledge of HPV risk also increased relative to the control (p = 0.0001). There were no significant differences between the intervention arms in increased knowledge of cervical cancer or cervical cancer screening (p = 0.57 and 0.16, respectively). DISCUSSION: This study supported the use of small media interventions in narrative education form as effective in increasing knowledge and intention to be screened for cervical cancer. The three culturally relevant interventions, built on qualitative data, were all successful in increasing knowledge.

County of Residence and Screening Practices among Latinas and Non-Latina Whites in Two Rural Communities.

Objectives: Latinas are less likely than non-Latina Whites (NLW) to utilize mammographic screening and are more likely to be diagnosed with late-stage breast cancer. Here, we examine the effects of county-level factors on guideline-concordant breast-cancer screening behaviors in Latinas and NLWs. Design: Latinas (N=108) and NLW women (N=132) aged >40 years, residing in two adjacent rural, medically underserved counties in eastern Washington State, completed a baseline questionnaire on mammography utilization and demographics. Main Outcome Measures: Differences in socioeconomic variables and knowledge of screening practices were examined by ethnicity and county of residence. Predictors of having had a mammogram within the past two years were analyzed using multivariate logistic regression. Results: Ethnicity was not associated with having a guideline-concordant mammogram; however, age (odds ratio [OR]=1.04, 95%CI:1.01-1.08); having >12 years of education (OR=2.09, 95%CI:1.16-3.79); having a regular clinic for health care (OR=2.22, 95%CI:1.05-4.70); having had a prior clinical breast exam (OR=5.07, 95%CI:1.71-15.02), and county of residence (OR=2.27, 95%CI:1.18-4.37) were all associated with having had a guideline-concordant mammogram. Conclusions: County of residence and having had a prior CBE were strong predictors of screening utilization. Community-level factors in medically underserved areas may influence screening patterns.

Developing a Culturally Informed Survey Instrument to Assess Biomedical Research Participation Among Latinos on the U.S.-Mexico Border.

Racial/ethnic minorities, rural populations, and those with low socioeconomic status income are underrepresented in research in the United States (U.S.). Assessing preferences for recruitment, participation, and the role of beliefs about biomedical research in specific and unique underserved communities represents a potentially critical step in reducing barriers to biomedical research participation. We developed a culturally informed survey to measure factors related to participation, knowledge, expectations, and barriers to biomedical research participation among Latinos living in a U.S. border community. We employed a multidisciplinary team approach to a sequential, three-phase qualitative study that included interviews ( n = 35), focus groups ( n =24), and "think-aloud" cognitive interviews ( n = 5). Our study demonstrates the value of applying multiple qualitative approaches to inform a culturally relevant quantitative survey incorporating words and constructs relevant to the population of interest. The study contributes to qualitative method research paradigms by developing a research protocol that integrates the expertise and perspectives of researchers and community members from multiple disciplines and institutions.

Una Mano Amiga: Pilot Test of a Patient Navigator Program for Southwest New Mexico.

We conducted a pilot test of a patient navigation intervention (Una Mano Amiga) to address cancer health disparities in three rural counties in southwest New Mexico. We trained two bilingual lay health workers (promotoras) as patient navigators (PNs) to help adult cancer patients and their participating families in Grant, Luna, and Hidalgo counties "navigate" the health care system, including appropriate access to social and financial services. Our hypothesized outcome was a reduction in time from diagnosis to treatment initiation compared to the average time without PNs in each of the three counties (2000-2009). We enrolled 85 eligible patients and 43 eligible family members who had completed psychosocial and demographic forms in this PN intervention. Mean time from cancer diagnosis to treatment initiation among 41 study patients was 59.6 days across the three counties. Mean time from non-intervention comparison data was 47.1 days. In the intervention group, on a 0-10 satisfaction scale (higher = more), patient mean scores for three items ranged from 9.3 to 9.6, family members, 8.9-9.3. Caregiver stress as measured by a Caregiver Self-Assessment score ≥ 10 (highest stress = 16) decreased from 23.8% of caregivers at study entry to 14.3% at follow-up (not statistically significantly different). Although the PN intervention did not decrease time from diagnosis to treatment initiation compared to three comparison counties, positive reactions of patients and family members support further research with larger samples.

Social factors matter in cancer risk and survivorship.

Greater attention to social factors, such as race/ethnicity, socioeconomic position, and others, are needed across the cancer continuum, including breast cancer, given differences in tumor biology and genetic variants have not completely explained the persistent Black/White breast cancer mortality disparity. In this commentary, we use examples in breast cancer risk assessment and survivorship to demonstrate how the failure to appropriately incorporate social factors into the design, recruitment, and analysis of research studies has resulted in missed opportunities to reduce persistent cancer disparities. The conclusion offers recommendations for how to better document and use information on social factors in cancer research and care by (1) increasing education and awareness about the importance of inclusion of social factors in clinical research; (2) improving testing and documentation of social factors by incorporating them into journal guidelines and reporting stratified results; and (3) including social factors to refine extant tools that assess cancer risk and assign cancer care. Implementing the recommended changes would enable more effective design and implementation of interventions and work toward eliminating cancer disparities by accounting for the social and environmental contexts in which cancer patients live and are treated.

Characterization of organophosphate pesticides in urine and home environment dust in an agricultural community.

CONTEXT: Organophosphorus insecticides (OPs) have been used to control agricultural pests found in Washington state. Farmworkers (FW) have higher exposure to OP pesticides than non-farmworkers (NFW), and FW children may in turn have higher exposure than NFW children. OBJECTIVE: To examine the association between the concentration in house dust of five OPs used commonly in pome fruit orchards and the concentration in urine of dialkylphosphate metabolites (DAP), in a cohort of Hispanic FW and NFW and their children. METHODS: Parents and children participated in three data collection periods over the course of one year. Urine samples were evaluated for the DAPs characteristic of OP exposure, and dust from homes and vehicles was evaluated for intact OP residues. RESULTS: Geometric mean (GM) concentrations of OPs in house and vehicle dust were higher in FW households than NFW households in all agricultural seasons. GM concentration of urinary DAPs was higher for children in FW households than NFW households. DISCUSSION: Regression analysis found a positive association between OP residues in house dust and the children's urinary DAPs. CONCLUSIONS: To our knowledge, this study is the first to report an association between pesticides in house dust and their biological metabolites in urine.

Knowledge and social engagement change in intention to be screened for colorectal cancer.

OBJECTIVE: Innovative technologies have been used to promote colorectal cancer (CRC) screening among the underserved. However, the impact of these innovative technologies on knowledge and social engagement likelihood as they relate to subsequent intention to be screened across different populations has not been fully explored. DESIGN: Using a pre-post-test design with an inflatable walk-through colon, we assessed changes in knowledge and social engagement likelihood across populations and their associations with intention to be screened in two community settings. One was a community setting in Washington State (WA); the other, a college campus in New Mexico (NM). Differential effects on knowledge and social engagement likelihood were examined across demographic groups (race/ethnicity, gender, age, education, insurance status, and geographic region). Finally, we assessed if changes in knowledge and social engagement likelihood were associated with CRC screening intention. RESULTS: NM males had greater gains in CRC knowledge than NM females; in WA, Hispanics, younger, less educated, and uninsured participants had greater gains in knowledge. NM females and younger WA participants were more likely to discuss CRC with their social networks than NM males and older WA participants. In WA, Hispanics and older adults reported greater intention to be screened for CRC. Change in social engagement likelihood, but not knowledge, was associated with intention to be screened. CONCLUSIONS: The effectiveness of health promotion technologies on knowledge and social engagement may vary across different demographic characteristics. Further, the importance of social engagement likelihood in interacting with intention to be screened was substantiated.

Association between iq'mik smokeless tobacco use and cardiometabolic risk profile among Yup'ik Alaska Native people.

OBJECTIVE: The traditional lifestyle of Yup'ik Alaska Native people, including a diet abundant in marine-based foods and physical activity, may be cardio-protective. However, iq'mik, a traditional form of smokeless tobacco used by >50% of Yup'ik adults, could increase cardiometabolic (CM) risk. Our objective was to characterize the associations between iq'mik use and biomarkers of CM status (low-density lipoprotein cholesterol [LDL-C], high-density lipoprotein cholesterol [HDL-C], triglycerides [TG], systolic blood pressure [SBP] and diastolic blood pressure [DBP], glycated hemoglobin [HbA1c], fasting blood glucose [FBG], waist circumference [WC], and body mass index [BMI]). DESIGN: We assessed these associations using data from a cross-sectional sample of Yup'ik adults (n = 874). Current iq'mik use, demographic, and lifestyle data were collected through interviews. Fasting blood samples were collected to measure LDL-C, HDL-C, TG, HbA1c, and FBG. SBP, DBP, WC, and BMI were obtained by physical examination. We characterized the association between current iq'mik use and continuous biomarkers of CM status using multiple approaches, including adjustment for measures of Yup'ik lifestyle and a propensity score. RESULTS: Based on either adjustment method, current iq'mik use was significantly and positively associated with at least 5% higher HDL-C, and significantly associated but in an inverse direction with multiple biomarkers of CM status including 7% lower TG, 0.05% lower HbA1c, 2% lower FBG, 4% lower WC, and 4% lower BMI. Observed associations for LDL-C, SBP, and DBP varied by adjustment method. CONCLUSIONS: This inverse association between iq'mik use and cardiometabolic risk status has not been previously reported. Additional research is needed to replicate these findings and explore physiological mechanisms and/or confounding factors.

Community Empowerment Partners (CEPs): A Breast Health Education Program for African-American Women.

Peer educators have been shown to provide effective interventions in breast cancer screening. Few studies have compared the effects of peer education on breast cancer knowledge among peer educators and the community members who are subsequently reached through the peer education. Further, little is known as to whether those who received the education then go on to educate others in the community. The purpose of this study is to address those gaps. Using a pre- and post-test study design, we trained peer educators, provided the educators with resources to train community members, and assessed changes in knowledge. We sought to train ten educators and recommended each train ten community members in breast cancer knowledge and screening strategies. A total of 14 peer educators were trained, who subsequently trained a total of 121 community members, of whom 94 were African American women. Peer educators and community members, showed comparable increases in knowledge. Community members who were educated also increased intention to discuss breast cancer and breast cancer screening with their family, friends, and acquaintances. Our study suggests that it is feasible to train peer educators to increase knowledge among community members to the same level that they themselves experience when trained. Further, community members are interested in sharing information learned related to how much they learn from peer educators.

Results of a randomized controlled trial to increase cervical cancer screening among rural Latinas.

BACKGROUND: Latinas have the highest rates of cervical cancer in the United States and the second highest rate of cervical cancer mortality. One factor in the disparity is the relatively low rate of screening for cervical cancer in this population. METHODS: Eligible women who were out of adherence with cervical cancer screening (>3 years since their last Papanicolaou [Pap] test) were identified via medical record review by a federally qualified local health center. The effects of a low-intensity intervention (video delivered to participants' homes; n = 150) and a high-intensity intervention (video plus a home-based educational session; n = 146) on cervical cancer screening uptake in comparison with a control arm (usual care; n = 147) were investigated. A cost-effectiveness analysis of the interventions was conducted: all intervention costs were calculated, and the incremental cost-effectiveness ratio was computed. Finally, women with positive Pap tests were provided navigation by a community health educator to ensure that they received follow-up care. RESULTS: A total of 443 Latinas participated. Seven months after randomization, significantly more women in the high-intensity arm received a Pap test (53.4%) in comparison with the low-intensity arm (38.7%; P < .001) and the usual-care arm (34.0%; P < .01). The incremental cost-effectiveness ratio for high-intensity women versus the control group amounted to $4.24. Twelve women had positive Pap tests, which encompassed diagnoses ranging from atypical squamous cells of unknown significance to invasive cancer; these women received navigation for follow-up care. CONCLUSIONS: A culturally appropriate, in-home, promotora-led educational intervention was successful in increasing cervical cancer screening among Latinas.

Human Oral Buccal Microbiomes Are Associated with Farmworker Status and Azinphos-Methyl Agricultural Pesticide Exposure.

In a longitudinal agricultural community cohort sampling of 65 adult farmworkers and 52 adult nonfarmworkers, we investigated agricultural pesticide exposure-associated changes in the oral buccal microbiota. We found a seasonally persistent association between the detected blood concentration of the insecticide azinphos-methyl and the taxonomic composition of the buccal swab oral microbiome. Blood and buccal samples were collected concurrently from individual subjects in two seasons, spring/summer 2005 and winter 2006. Mass spectrometry quantified blood concentrations of the organophosphate insecticide azinphos-methyl. Buccal oral microbiome samples were 16S rRNA gene DNA sequenced, assigned to the bacterial taxonomy, and analyzed after "centered-log-ratio" transformation to handle the compositional nature of the proportional abundances of bacteria per sample. Nonparametric analysis of the transformed microbiome data for individuals with and without azinphos-methyl blood detection showed significant perturbations in seven common bacterial taxa (>0.5% of sample mean read depth), including significant reductions in members of the common oral bacterial genus Streptococcus Diversity in centered-log-ratio composition between individuals' microbiomes was also investigated using principal-component analysis (PCA) to reveal two primary PCA clusters of microbiome types. The spring/summer "exposed" microbiome cluster with significantly less bacterial diversity was enriched for farmworkers and contained 27 of the 30 individuals who also had azinphos-methyl agricultural pesticide exposure detected in the blood. IMPORTANCE: In this study, we show in human subjects that organophosphate pesticide exposure is associated with large-scale significant alterations of the oral buccal microbiota composition, with extinctions of whole taxa suggested in some individuals. The persistence of this association from the spring/summer to the winter also suggests that long-lasting effects on the commensal microbiota have occurred. The important health-related outcomes of these agricultural community individuals' pesticide-associated microbiome perturbations are not understood at this time. Future investigations should index medical and dental records for common and chronic diseases that may be interactively caused by this association between pesticide exposure and microbiome alteration.

Development of mobile technologies for the prevention of cervical cancer in Santiago, Chile study protocol: a randomized controlled trial.

BACKGROUND: In Chile, more than 500 women die every year from cervical cancer, and a majority of Chilean women are not up-to-date with their Papanicolau (Pap) test. Mobile health has great potential in many health areas, particularly in health promotion and prevention. There are no randomized controlled trials in Latin America assessing its use in cervical cancer screening. The 'Development of Mobile Technologies for the Prevention of Cervical Cancer in Santiago, Chile' study aims to determine the efficacy of a text-message intervention on Pap test adherence among Chilean women in the metropolitan region of Santiago. METHODS/DESIGN: This study is a parallel randomized-controlled trial of 400 Chilean women aged 25-64 who are non-adherent with current recommendations for Pap test screening. Participants will be randomly assigned to (1) a control arm (usual care) or (2) an intervention arm, where text and voice messages containing information and encouragement to undergo screening will be sent to the women. The primary endpoint is completion of a Pap test within 6 months of baseline assessment, as determined by medical record review at community-based clinics. Medical record reviewers will be blinded to randomization arms. The secondary endpoint is an evaluation of the implementation and usability of the text message intervention as a strategy to improve screening adherence. DISCUSSION: This intervention using mobile technology intends to raise cervical cancer screening adherence and compliance among a Chilean population of low and middle-low socioeconomic status. If successful, this strategy may reduce the incidence of cervical cancer. TRIAL REGISTRATION: Clinicaltrials.gov NCT02376023 Registered 2/17/2015. First participant enrolled Feb 22nd 2016.

Exploring the role of physician communication about adjuvant endocrine therapy among breast cancer patients on active treatment: a qualitative analysis.

PURPOSE: To better understand how physicians communicate with breast cancer patients about adjuvant endocrine therapy (AET), we explored, from the breast cancer patient's perspective, dimensions of the patient-provider communication among women who were on active AET treatment. METHODS: Qualitative methods using semi-structured in-depth interviews were conducted with breast cancer patients (n = 22) who filled a prescription for AET in the previous 12 months. Interview questions aimed to elicit experiences with AET. We reviewed and coded interview transcripts using qualitative principles of inductive reasoning to identify concepts and themes from interview data. RESULTS: We grouped emergent themes into four major functions of physician-patient communication: (1) information exchange, (2) decision-making to take and continue AET, (3) enabling patient self-management and monitoring potential side effects, and (4) emotional support. Physicians exchanged information with patients in a way that they understood and enhanced patient's health literacy regarding the benefits and knowledge of AET. Physicians empowered patients to make decisions about their care. Patients expressed trust and confidence in their physician which helped them seek care when needed. Patients reported a high degree of self-efficacy to self-manage AET and were continuing treatment despite potential side effects. CONCLUSIONS: The results from our study suggest that women's interactions and communication with their physician may be an important factor that contributes to the continued use of AET. Physicians who can communicate information about AET treatment benefits, purpose, and expectations in a way that patients can understand is a critical aspect of care that needs to be further studied.
