Association Between Social Determinants of Health and Glycemic Control Among African American People with Type 2 diabetes: The Jackson Heart Study.

BACKGROUND: Social determinants of health have a significant impact on health outcomes. However, the complexity and interaction of multiple factors influencing glycemic control remain understudied. PURPOSE: This study examined associations of socioeconomic position (income, education, and occupation), environmental (physical activity facilities, neighborhood social cohesion, neighborhood problem, and violence), behavioral (physical activity, nutrition, and smoking), and psychological factors (depressive symptoms, stress, and discrimination) with glycemic control (hemoglobin A1c [A1c]) using the World Health Organization Social Determinants of Health framework in African American adults with type 2 diabetes. METHODS: A secondary data analysis was conducted using a longitudinal cohort of 1,240 African American adults with type 2 diabetes who participated in the community-based Jackson Heart Study. Socioeconomic position, environmental, behavioral, and psychological factors were measured using validated instruments in the Jackson Heart Study. Longitudinal structural equation modeling was used with glycemic control (A1c) collected over time (Exams 1-3) as the study outcome. RESULTS: Our study presents the complex interplay of socioeconomic determinants of health and glycemic control over time. Higher socioeconomic position (higher income, higher level of education, and professional occupation) was directly associated with improvement in glycemic control over time. An association of socioeconomic position on glycemic control mediated through health behavior factors was also observed. CONCLUSIONS: In this analysis, socioeconomic position components were determinants of glycemic control in African American adults with type 2 diabetes. Future studies aimed at reducing health disparities and achieving equality of outcomes in this population will benefit from embedding socioeconomic position components into their design.

Methodologic Considerations for Epigenomic Investigation of Preterm Birth in African American Women.

Epigenetic modifications are chemical changes that can modify gene expression without changing the sequence of the gene. These modifications are potentially identifiable and reversible, making the epigenome an important area of research for discovering biomarkers to identify those who may be at risk and providing therapeutic interventions to prevent adverse health outcomes. African Americans bear a disproportionate risk of adverse health outcomes (e.g., hypertension, cancer). Indeed, African American women experience preterm birth (PTB; <37 completed weeks gestation) at more than twice the rate of non-Hispanic White women. Research suggests that environmental influences may play a significant role in PTB outcomes for this population. However, the biological pathways by which these influences contribute to PTB are poorly understood. This paper describes research methods and ethical considerations for the collection and analysis of biological samples based on our study examining the epigenetic regulation of stress pathways in PTB in pregnant African American women.

Feasibility and Acceptability of a Reiki Intervention With Very Young Children Receiving Palliative Care.

BACKGROUND: Very little research has been reported examining nonpharmacological symptom management strategies for very young, hospitalized children receiving palliative care, and none has involved Reiki-a light touch therapy. OBJECTIVES: The aim of this study was to determine if completing a Reiki intervention with hospitalized 1- to 5-year-old children with chronic, life-limiting conditions receiving palliative care was feasible and acceptable. METHODS: Children ages 1-5 years receiving palliative care who were expected to be hospitalized for at least 3 weeks were recruited for a single-arm, mixed-methods, quasi-experimental pre- and poststudy. Six protocolized Reiki sessions were conducted over 3 weeks. We calculated feasibility by the percentage of families enrolled in the study and acceptability by the percentage of families who completed all measures and five out of six Reiki sessions. Measures were collected at baseline, at the end of the intervention period, and 3 weeks later. At the final follow-up visit, parents were verbally asked questions relating to the acceptability of the intervention in a short structured interview. RESULTS: We screened 90 families, approached 31 families, and recruited 16 families, whereas 15 families declined. Reasons for not participating included that the child had "a lot going on," would be discharged soon, and families were overwhelmed. Of those enrolled, most completed all measures at three time points and five out of six Reiki sessions. We completed nearly all scheduled Reiki sessions for families that finished the study. All parents reported that they would continue the Reiki if they could, and almost all said they would participate in the study again; only one parent was unsure. DISCUSSION: Young children and their parents found Reiki acceptable; these results are comparable to an earlier study of children 7-16 years of age receiving palliative care at home and a study of massage for symptom management for hospitalized children with cancer. These findings add to the literature and support further investigation of Reiki's efficacy as a nonpharmacological symptom management intervention.

Critical Care Nurses' Physical and Mental Health, Worksite Wellness Support, and Medical Errors.

BACKGROUND: Critical care nurses experience higher rates of mental distress and poor health than other nurses, adversely affecting health care quality and safety. It is not known, however, how critical care nurses' overall health affects the occurrence of medical errors. OBJECTIVE: To examine the associations among critical care nurses' physical and mental health, perception of workplace wellness support, and self-reported medical errors. METHODS: This survey-based study used a cross-sectional, descriptive correlational design. A random sample of 2500 members of the American Association of Critical-Care Nurses was recruited to participate in the study. The outcomes of interest were level of overall health, symptoms of depression and anxiety, stress, burnout, perceived worksite wellness support, and medical errors. RESULTS: A total of 771 critical care nurses participated in the study. Nurses in poor physical and mental health reported significantly more medical errors than nurses in better health (odds ratio [95% CI]: 1.31 [0.96-1.78] for physical health, 1.62 [1.17-2.29] for depressive symptoms). Nurses who perceived that their worksite was very supportive of their well-being were twice as likely to have better physical health (odds ratio [95% CI], 2.16 [1.33-3.52]; 55.8%). CONCLUSION: Hospital leaders and health care systems need to prioritize the health of their nurses by resolving system issues, building wellness cultures, and providing evidence-based wellness support and programming, which will ultimately increase the quality of patient care and reduce the incidence of preventable medical errors.

The ties that bind: Cancer history, communication, and screening intention associations among diverse families.

OBJECTIVE: Breast and cervical cancers are screen-detectable; yet, challenges exist with ensuring uptake of mammography and Pap smear. Family, a central factor in developing knowledge to carry out health promotion behaviors, may be an asset to improving intention to screen among non-adherent women from underrepresented minority groups. We explored familial cancer; communication; and breast and cervical screening intention among non-adherent Black, Latina, and Arab women in the United States who participated in a randomized controlled trial of the Kin KeeperSM Cancer Prevention Intervention study. The intervention was a culturally-targeted breast and cervical cancer literacy tool for Black, Latina, and Arab women, consisting of two family-focused education sessions on the cancers, their screening guidelines, and risk-reducing health-related behaviors. METHODS: For this secondary analysis, we assessed family cancer history, family communication, and screening intention for breast and cervical cancer in age-eligible, non-adherent participants. Descriptive statistics examined sample characteristics of the intervention and control groups. Odds ratios were estimated from logistic regression modeling to assess the intervention and sample characteristic effects on screening intention. RESULTS: Of the 516 participants, 123 and 98 were non-adherent to breast and cervical cancer screening, respectively. The intervention (OR = 1.95 for mammography; OR = 1.62 for Pap smear) and highly communicative (OR = 2.57 for mammography; OR = 3.68 for Pap smear) families reported greater screening intention. Family history of cancer only increased screening intention for mammography (OR = 2.25). CONCLUSION: Family-focused approaches supporting communication may increase breast and cervical cancer screening intention among non-adherent, underrepresented minority groups.

Strain Among Caregivers of Older Adults Diagnosed With Breast Cancer.

OBJECTIVES: To illustrate the predictors of strain among caregivers of older adults diagnosed with breast cancer. SAMPLE & SETTING: This study involved 39 women diagnosed with breast cancer who were aged 69 years or older, receiving any type of treatment, and seeking an initial assessment in a geriatric oncology program at a large cancer center in the midwestern United States and their caregivers. METHODS & VARIABLES: This cross-sectional study evaluated relationships among the variables of caregiver strain, age, employment status, patient characteristics, and patient scores on the comprehensive geriatric assessment. Bivariate statistics and logistic regression models were used. RESULTS: Increasing age of the caregiver was associated with less caregiver strain. Caregivers employed part-time experienced greater strain than those employed full-time. IMPLICATIONS FOR NURSING: Nurses must assess for strain in caregivers of individuals diagnosed with cancer, particularly if they are younger and employed part-time. Caregivers of depressed patients should be assessed for strain and offered support.

Utilization of an audit tool to evaluate accuracy of treatment summary and survivorship care plans.

PURPOSE: A quality review process was implemented to determine compliance with the requirement from the Commission on Cancer to use the American Society of Clinical Oncology (ASCO) template as the minimum data set for Treatment Summary and Survivorship Care Plans (TS/SCP) provided to cancer survivors. METHODS: TS/SCPs generated during 2017 (N = 1257) were audited for concordance with each of the 66 TS/SCP line items on ASCO's template. Descriptive statistics and chi-square statistics were used to examine line item concordance, overall and by services groups (survivorship vs. other oncology service). Mixed-effects logistic regression was used to estimate the effects of service delivery group on the concordance. RESULTS: Institutional compliance with the ASCO template was very high; 76% of the 66 line items were present in at least 75% of the delivered TS/SCPs. There was a significantly higher rate of concordance for TS/SCPs provided by the survivorship service (83% vs. 66%, P = 0.006). TS/SCPs provided by the survivorship service were nearly twice as likely to be concordant with ASCO template (OR = 1.88, 95% CI = 1.77-2.00) compared to those by other service groups. CONCLUSIONS: Use of the electronic medical record to auto-populate information was instrumental in achieving a high rate of concordance. Institutions should consider providing training to improve or maintain quality of these documents. IMPLICATIONS FOR CANCER SURVIVORS: Ensuring that the information contained on the TS/SCP is consistently present is necessary for a high-quality survivorship visit between the clinician, PCP, and survivor and as a record of care for future health care encounters.

Associations Between Stress and Cardiovascular Disease Risk Factors Among Million Hearts Priority Populations.

PURPOSE: To estimate the effects of stress on hypertension and high cholesterol with a focus on Million Hearts priority populations. DESIGN: A population-based cross-sectional survey on cardiovascular health and its risk factors. SETTING: Million Hearts cardiovascular community screenings. SAMPLE: Deidentified data were collected on a convenience sample of 59 798 participants. MEASURES: Self-reported stress score using the Perceived Stress Scale-4 (PSS-4), blood pressure, and total cholesterol. ANALYSIS: Descriptive statistics were used to estimate the prevalence of high stress (PSS-4 score ≥ 9), prehypertension or hypertension, and elevated total cholesterol. Multiple logistic regression modeling was used to estimate the effect of stress on the risk of elevated blood pressure and total cholesterol. RESULTS: Twenty-four percent of the participants had high stress. Younger participants had an increased prevalence of high stress than older participants (28% vs 20%, P < .001). African Americans had a high prevalence of stress (26.4%), prehypertension or hypertension (65.4%), and elevated total cholesterol (48.6%). Compared to those with low stress, high stress was associated with significant higher risks of having prehypertension/hypertension (odds ratio [OR] = 1.40, 95% confidence interval [CI] = 1.28-1.53) and elevated cholesterol (OR = 1.53, 95% CI = 1.41-1.66). CONCLUSIONS: Stress needs to be routinely identified and treated, especially in Million Hearts priority populations. More research is needed in designing culturally sensitive and effectively tailored interventions relative to both stress and disease management.

Relationships between stress, demographics and dietary intake behaviours among low-income pregnant women with overweight or obesity.

OBJECTIVE: To identify demographic risk factors associated with high stress and examine the relationships between levels of stress, demographics and dietary fat, fruit and vegetable intakes in low-income pregnant women with overweight or obesity. DESIGN: A cross-sectional study. SETTING: Participants were recruited from the Special Supplemental Nutrition Program for Women, Infants, and Children in Michigan, USA.ParticipantsParticipants (n 353) were non-Hispanic Black (black) or White (white). RESULTS: Women aged 35 years or older (OR=4·09; 95% CI 1·45, 11·51) and who had high school or less education (OR=1·88; 95% CI 1·22, 2·89) or were unemployed (OR=1·89; 95% CI 1·15, 3·12) were significantly more likely to report high stress than women who were younger, had at least some college education or were employed/homemakers. However, race and smoking status were not associated with level of stress. Women with high stress reported significantly lower fruit and vegetable intakes but not fat intake than women with low stress. Women aged 35 years or older reported significantly higher vegetable but not fat or fruit intake than women who were 18-24 years old. Black women reported significantly higher fat but not fruit or vegetable intake than white women. Education, employment and smoking status were not significantly associated with dietary intake of fat, fruits and vegetables. CONCLUSIONS: Nutrition counselling on reducing fat and increasing fruit and vegetable intakes may consider targeting women who are black or younger or who report high stress, respectively.

Effects of Menthol Flavor Cigarettes or Total Urinary Menthol on Biomarkers of Nicotine and Carcinogenic Exposure and Behavioral Measures.

INTRODUCTION: The effects of either menthol flavor cigarettes or total urinary menthol on nicotine dependence, biomarkers of addictive and carcinogenic exposure, and behavioral measures may inform differences and similarities of these two approaches. METHODS: Stratified recruitment by cigarette (menthol flavor or regular) and race (African American and white) yielded a balanced sample of 136 adult smokers in a 36-hour inpatient protocol. Exposure measures assessed during 24-hour data collection included urinary menthol, total NNAL [4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol], 10 polycyclic aromatic hydrocarbon metabolites, baseline plasma cotinine, plasma nicotine pre- and post-smoking, exhaled carbon monoxide pre- and post-smoking, and cigarette puff volumes. The latter three were measured at four specified timepoints throughout the day. RESULTS: There were no significant differences between menthol flavor and regular cigarette smokers in measures of nicotine dependence, biomarkers of addictive and carcinogenic exposures, or behavioral measures. Significant race × cigarette type interaction effects were found for two biomarkers: plasma nicotine and 3-hydroxyphenanthrene. Total urinary menthol was significantly associated with higher levels of nearly all dependent variables including puff volume, exhaled carbon monoxide, plasma nicotine and cotinine, NNAL, and polycyclic aromatic hydrocarbons. The significant effects of total urinary menthol were sustained after adjusting for menthol flavor and regular cigarette type and other covariates (eg, number of cigarettes per day, baseline cotinine, and baseline nicotine). CONCLUSIONS: Urinary menthol is an independent predictive biomarker for nicotine dependence, addictive and carcinogenic exposure, and behaviors. IMPLICATIONS: Comparison of the effects of menthol flavor and total urinary menthol on nicotine dependence, biomarkers of addictive and carcinogenic exposure, and behavioral measures emphasizes the important significant contribution of total urinary menthol concentrations in contrast to no significant associations by dichotomous cigarette type with these biomarkers.

Perceptions of overdetection of breast cancer among women 70 years of age and older in the USA: a mixed-methods analysis.

OBJECTIVES: Current research on the perceptions of overdiagnosis or overdetection of breast cancer has largely been conducted outside of the USA and with women younger than 70 years.Therefore, we explored older women's perceptions about the concept of overdetection of breast cancer and its influence on future screening intentions. DESIGN: Mixed-methods analysis using purposive sampling based on race/ethnicity, age and educational level. Semistructured interviews, including two hypothetical scenarios illustrating benefits and harms of screening and overdetection, were analysed using inductive and deductive thematic approaches. An inferential clustering technique was used to assess overall patterns in narrative content by sociodemographic characteristics, personal screening preferences or understanding of overdetection. SETTING: Houston/Galveston, Texas, USA. PARTICIPANTS: 59 English-speaking women aged 70 years and older with no prior history of breast cancer. RESULTS: Very few women were familiar with the concept of overdetection and overtreatment. After the scenarios were presented, half of the women still demonstrated a lack of understanding of the concept of overdetection. Many women expressed suspicion of the concept, equating it to rationing. Women who showed understanding of overdetection were more likely to express an intent to discontinue screening, although 86% of the women stated that hearing about overdetection did not influence their screening decision. Themes identified did not differ by race/ethnicity, education, age or screening preferences. Differences were identified between women who understood overdetection and women who did not (r=0.23, p<0.001). CONCLUSIONS: Many older women did not understand the concept of overdetection, in addition to being suspicious of or resistant to the concept. Providing older women with descriptions of overdetection may not be sufficient to influence screening intentions.

The Sun Solutions Intervention for Operating Engineers: A Randomized Controlled Trial.

Background: Because Operating Engineers (heavy equipment operators) are outdoor workers at risk for skin cancer, interventions are needed to promote sun safety. The objectives were to determine changes in sunscreen use and sunburning among Operating Engineers randomized to four conditions in the Sun Solutions study: (i) education only; (ii) education and text message reminders; (ii) education and mailed sunscreen; and (iv) education, text message reminders, and mailed sunscreen.Methods: In this randomized controlled trial, Operating Engineers (N = 357) were recruited at required safety training sessions throughout Michigan during winter/spring of 2012 to 2013 and provided baseline surveys. The four interventions were delivered over the summer. Postintervention surveys were collected in the fall (82.1% follow-up).Results: Sunscreen use improved significantly from baseline to follow-up in all four conditions (P < 0.05), except sunscreen use among those receiving education and text message reminders was only marginally significant (P = 0.07). There were significantly greater increases in sunscreen use in the two conditions that were mailed sunscreen (P < 0.001). There was a significant decrease in the number of reported sunburns from baseline to follow-up in all four conditions (P < 0.001), but there were no significant differences in sunburns among the groups. Participant evaluated the interventions highly with those who received mailed sunscreen rating the intervention the highest.Conclusions: Providing proper sun-safety education and minimizing barriers to sunscreen use can increase sunscreen use and decrease reported sunburns.Impact: The implementation of the Sun Solutions intervention may be an effective method to modify skin cancer-related behaviors.

Supplementation with eicosapentaenoic acid and docosahexaenoic acid reduces high levels of circulating proinflammatory cytokines in aging adults: A randomized, controlled study.

BACKGROUND: High levels of circulating proinflammatory cytokines are characteristic of inflammaging, a term coined to describe age-related chronic systemic inflammation involved in the etiology of many age-related disorders including nonhealing wounds. Some studies have shown that supplementing diets with n-3 polyunsaturated fatty acids (eicosapentaenoic acid [EPA] and docosahexaenoic acid [DHA]) lowers systemic levels of key proinflammatory cytokines associated with inflammaging. However, findings from the few studies that have focused exclusively on older adults are inconclusive. As such, the objective of this randomized controlled study was to test the effects of EPA+DHA therapy on circulating levels of proinflammatory cytokines in adults in middle to late adulthood. METHODS: Plasma levels of fatty acids and interleukin (IL)-6, IL-1ß and tumor necrosis factor-α (TNF-α) were measured in 35 participants with chronic venous leg ulcers (mean age: 60.6 years) randomnly assigned to 8 weeks of EPA+DHA therapy (2.5 g/d) or placebo therapy. RESULTS: EPA+DHA therapy had a significant lowering effect on levels of IL-6, IL-1ß and TNF-α after 4 weeks of therapy and an even greater lowering effect after 8 weeks of therapy. Further, after adjusting for baseline difference, the treatment group had significantly lower levels of IL-6 (p = 0.008), IL-1ß (p < 0.001), and TNF-α (p < 0.001) at Week 4 and at Week 8 [IL-6 (p = 0.007), IL-1ß (p < 0.001), and TNF-α (p < 0.001)] compared to the control group. CONCLUSION: Adults in middle to late adulthood receiving EPA+DHA therapy demonstrated significantly greater reductions in circulating levels of proinflammatory cytokines compared with those receiving placebo therapy. EPA+DHA therapy may be an effective low-risk dietary intervention for assuaging the harmful effects of inflammaging.

Factors Associated With Poor Sleep in Older Women Diagnosed With Breast Cancer

OBJECTIVES: To determine the relationship among gait, grip strength, cognition, depression, pain, and fatigue, and to identify which variables are most predictive of poor sleep. SAMPLE & SETTING: 60 women with breast cancer aged 69 years or older who were receiving treatment in the Senior Adult Oncology Program at the James Cancer Hospital at the Ohio State University. METHODS & VARIABLES: The variables were gait and grip strength (functional domains), cognition, depression, pain, and fatigue. Patients were tested using the Timed Up and Go Test (TUG), Jamar Hydraulic Hand Dynamometer, Mini-Cog, Numeric Pain Rating Scale, Brief Fatigue Inventory, Geriatric Depression Scale, and Pittsburgh Sleep Quality Index. Pearson correlation coefficients and logistic regression models were used. RESULTS: The mean age of the sample was 78 years. Pain and fatigue, depression and pain, and depression and fatigue each were positively related, and grip strength and TUG scores were negatively related. Fatigue was the strongest predictor of poor sleep. IMPLICATIONS FOR NURSING: These findings are important to the comprehensive care of older women diagnosed with breast cancer. Understanding symptoms associated with poor sleep helps nurses develop comprehensive care plans for older adults with breast cancer.

An Epidemiological Study of Population Health Reveals Social Smoking as a Major Cardiovascular Risk Factor.

PURPOSE: To present nationally representative data on the prevalence of "social" smoking and its relationship to cardiovascular health. DESIGN: A population-based, cross-sectional survey on cardiovascular health and its risk factors across the United States. SETTING: Million Hearts® cardiovascular screenings that took place in community settings. PARTICIPANTS: De-identified data were collected on a convenient sample of 39, 555 participants. MEASURES: Reported smoking status, blood pressure, and total cholesterol. ANALYSIS: The prevalence of current smoking, social smoking, and non-smoking were cross-tabulated and stratified by sample characteristics. The adjusted estimates were derived from multiple logistic regression models, adjusting for demographics and other biometric measures. RESULTS: Ten percent identified as social smokers. Social smokers were more likely to be aged between 21 and 40, male, and Hispanic. Social smokers had significantly higher risks of having hypertension (odds ratio [OR]: 2.08, 95% confidence interval [CI]: 1.80-2.41) and elevated cholesterol (OR: 1.53, 95% CI: 1.33-1.75) than non-smokers. There was no significant difference between social smokers and current smokers (OR = 0.94, 95% CI = 0.80-1.14 for hypertension and OR = 0.95, 95% CI = 0.81-1.11 for elevated cholesterol). CONCLUSION: This is the first population health study to compare the blood pressure and cholesterol levels of people who self-identify as current verses social smokers. Although previous smoking behavior was not controlled for in the analysis, this study demonstrates there is no significant difference in the prevalence of elevated blood pressure or cholesterol among the 2 smoking groups.

A National Study Links Nurses' Physical and Mental Health to Medical Errors and Perceived Worksite Wellness.

OBJECTIVE: The aim of this study was to describe (1) nurses' physical and mental health; (2) the relationship between health and medical errors; and (3) the association between nurses' perceptions of wellness support and their health. METHODS: A cross-sectional descriptive survey was conducted with 1790 nurses across the U.S. RESULTS: Over half of the nurses reported suboptimal physical and mental health. Approximately half of the nurses reported having medical errors in the past 5 years. Compared with nurses with better health, those with worse health were associated with 26% to 71% higher likelihood of having medical errors. There also was a significant relationship between greater perceived worksite wellness and better health. CONCLUSION: Wellness must be a high priority for health care systems to optimize health in clinicians to enhance high-quality care and decrease the odds of costly preventable medical errors.

Perceptions of Cervical Cancer Screening, Screening Behavior, and Post-Migration Living Difficulties Among Bhutanese-Nepali Refugee Women in the United States.

Bhutanese-Nepali refugees are one of the largest refugee groups to be resettled in the U.S. in the past decade. Cervical cancer is a leading cause of cancer disparity in this population, yet screening rates are suboptimal. Nepali-speaking interviewers administered a community health needs questionnaire to a convenience sample of Bhutanese-Nepali refugees in a Midwestern city between July to October of 2015. Descriptive statistics were used to describe socio-demographic characteristics, Pap smear beliefs, post-migration living difficulties, and screening status. Differences in Pap test uptake between groups were tested using t test and Chi square statistics. Of the 97 female participants, 44.3% reported ever having had a Pap smear. Screening rates were lowest among women who did not know English at all. Most women had positive perceptions of Pap smears (80%) and 44.4% had received a Pap test recommendation from their healthcare provider, family, or friends. Pap testing was significantly higher among those who had positive perceptions (58.3 vs. 11.1% for women of negative perception, p = 0.01) and those who had received a recommendation (87.5 vs. 18.6% for women who had no recommendations, p < 0.001). Significant predictors of having a Pap smear were having a healthcare provider/family/friends recommendation (OR 65.3, 95% CI 11.4-373.3) and greater number of post-migration living difficulties (OR 1.18, 95% CI 1.02-1.37). The results of this study have important implications for the development of cervical cancer prevention programs targeting Bhutanese-Nepali refugees. Providing cancer prevention interventions early in the resettlement process could impact Pap test uptake in this population.

Receipt of Cancer Screening Is a Predictor of Life Expectancy.

BACKGROUND: Obtaining cancer screening on patients with limited life expectancy has been proposed as a measure for low quality care for primary care physicians (PCPs). However, administrative data may underestimate life expectancy in patients who undergo screening. OBJECTIVE: To determine the association between receipt of screening mammography or PSA and overall survival. DESIGN: Retrospective cohort study from 1/1/1999 to 12/31/2012. Receipt of screening was assessed for 2001-2002 and survival from 1/1/2003 to 12/31/2012. Life expectancy was estimated as of 1/1/03 using a validated algorithm, and was compared to actual survival for men and women, stratified by receipt of cancer screening. PARTICIPANTS: A 5 % sample of Medicare beneficiaries aged 69-90 years as of 1/1/2003 (n = 906,723). INTERVENTIONS: Receipt of screening mammography in 2001-2002 for women, or a screening PSA test in 2002 for men. MAIN MEASURES: Survival from 1/1/2003 through 12/31/2012. KEY RESULTS: Subjects were stratified by life expectancy based on age and comorbidity. Within each stratum, the subjects with prior cancer screening had actual median survivals higher than those who were not screened, with differences ranging from 1.7 to 2.1 years for women and 0.9 to 1.1 years for men. In a Cox model, non-receipt of screening in women had an impact on survival (HR = 1.52; 95 % CI = 1.51, 1.54) similar in magnitude to a diagnosis of complicated diabetes or heart failure, and was comparable to uncomplicated diabetes or liver disease in men (HR = 1.23; 1.22, 1.25). CONCLUSIONS: Receipt of cancer screening is a powerful marker of health status that is not captured by comorbidity measures in administrative data. Because life expectancy algorithms using administrative data underestimate the life expectancy of patients who undergo screening, they can overestimate the problem of cancer screening in patients with limited life expectancy.

Decreased miR-199 augments visceral pain in patients with IBS through translational upregulation of TRPV1.

OBJECTIVE: Many patients with irritable bowel syndrome IBS not only have abdominal pain but also may suffer from visceral hypersensitivity and heighted visceral nociception. Moreover, IBS has few effective therapeutic agents and mechanisms of disease are unclear. Our goals were to (i) identify microRNA (miRNA) expression, signalling and targets in human colon (controls; patients with IBS); (ii) verify in vitro, IBS-associated changes in miRNAs, especially miR-199, which is complementary to the transient receptor potential vanilloid type 1 (TRPV1) gene; and (iii) determine whether modulating the expression of miRNAs in vivo, especially miR-199, reverses associated changes and pathological hallmarks of visceral hypersensitivity via TRPV1 signalling. DESIGN: We evaluated 45 patients with diarrhoea-predominant IBS (IBS-D) and 40 controls with (1) visceral pain severity score and (2) colonoscopy with biopsies. miRNA expression was evaluated in human colon following miRNA array analysis. Luciferase assays were done to confirm relationships between miR-199 and TRPV1 expression. A rat model of visceral hypersensitivity was used to study miR-199 and its target gene (TRPV1) expression in dorsal root ganglion (DRG) and colon in vivo. RESULTS: Gut miR-199a/b expression in IBS-D was significantly decreased, which correlated directly with both increased visceral pain scores and TRPV1 expression. In vivo upregulation of miR-199a by intraperitoneal injection of lenti-miR-199a precursors decreased visceral hypersensitivity via diminished TRPV1 signalling. CONCLUSIONS: Decreased colonic miR-199a/b correlates with visceral pain in patients with IBS-D. Similarly, reduced miR-199a expression in rat DRG and colon tissue is associated with heightened visceral hypersensitivity. In vivo upregulation of miR-199a decreases visceral pain via inhibition of TRPV1 signalling. Thus, miR-199 precursors may be promising therapeutic candidates for the treatment in patients with visceral pain.
