Afraid and tired: A longitudinal study of the relationship between cancer-related fatigue and fear of cancer recurrence in long-term cancer survivors.

OBJECTIVE: Cancer-related fatigue (CRF) and fear of cancer recurrence (FCR) are two common concerns experienced by cancer survivors. However, the relationship between these two concerns is poorly understood, and whether CRF and FCR influence each other over time is unclear. METHODS: Data were from a national, prospective, longitudinal study, the American Cancer Society's Study of Cancer Survivors-I (SCS-I). Surveys were completed by 1395 survivors of 10 different cancer types at three time-points, including assessment 1.3 years (T1), 2.2 years (T2) and 8.8 years (T3) following their cancer diagnosis. CRF was assessed using the fatigue-inertia subscale of the Profile of Mood States, and FCR by the FCR subscale of the Cancer Problems in Living Scale. Multiple group random intercepts cross-lagged panel models investigated prospective associations between CRF and FCR. RESULTS: For younger participants (at or below median age of 55 years, n = 697), CRF at T1 and T2 marginally and significantly predicted FCR at T2 and T3, respectively, but no lagged effects of FCR on subsequent CRF were observed. Cross-lagged effects were not observed for survivors over 55 years of age. CONCLUSION: Both CRF and FCR are debilitating side effects of cancer and its treatments. Given that CRF may be predictive of FCR, it possible that early detection and intervention for CRF could contribute to lowering FCR severity.

Longitudinal analysis of peer social support and quitting Smoking: Moderation by sex and implications for cessation interventions.

Social support predicts better health and lower mortality, but the benefits of peer social support for helping cigarette smokers quit are unclear. Moreover, sex as a moderating factor has not been investigated despite sex differences in social support processes. This study of smokers' perceived availability of peer social support in quitting cigarette smoking is a secondary analysis of 1,010 individuals enrolled in an RCT that provided quitting assistance using tailored emails scheduled around a quit date. Participants completed measures of peer support for quitting cigarettes at enrollment (baseline), and at 1-, 3-, and 6-month follow-ups. Peer support at follow-ups was categorized as never-present, always-present, or mixed. A Generalized Estimating Equation (GEE) examined the association between peer support and 7-day point prevalence abstinence at follow-ups, controlling for baseline peer support, experimental condition, stress, depression, and sociodemographic and smoking behavior-related variables. Interactions of peer support × time, and peer support × sex, were tested. Results indicated that among women, always-present or mixed peer support was associated with, respectively, odds of abstinence that were 4.36 (95 % CI, 2.54-7.49, p = 0.0001), and 2.21 (OR = 2.21, 95 % CI, 1.27-3.85, p = 0.005) greater than among women reporting never-present peer support. Among men, peer support did not predict abstinence. Women who smoke may be especially receptive to the benefits of peer support when attempting to quit. Investigation of the basis of their perceptions, how they might be increased, and whether interventions to change them would be effective, is warranted.

Cancer health self-efficacy improvement in a randomized controlled trial.

BACKGROUND: eHealth interventions can help cancer survivors self-manage their health outside the clinic. Little is known about how best to engage and assist survivors across the age and cancer treatment spectra. METHODS: The American Cancer Society conducted a randomized controlled trial that assessed efficacy of, and engagement with, Springboard Beyond Cancer, an eHealth self-management program for cancer survivors. Intent-to treat analyses assessed effects of intervention engagement for treatment (on-treatment vs completed) overall (n = 176; 88 control, 88 intervention arm) and separately by age (<60 years vs older). Multiple imputation was used to account for participants who were lost to follow-up (n = 41) or missing self-efficacy data (n = 1) at 3 months follow-up. RESULTS: Self-efficacy for managing cancer, the primary outcome of this trial, increased significantly within the intervention arm and for those who had completed treatment (Cohen's d = 0.26, 0.31, respectively). Additionally, participants with moderate-to-high engagement in the text and/or web intervention (n = 30) had a significantly greater self-efficacy for managing cancer-related issues compared to the control group (n = 68), with a medium effect size (Cohen's d = 0.44). Self-efficacy did not differ between the intervention and control arm at 3 months post-baseline. CONCLUSIONS: Study results suggest that cancer survivors benefit variably from eHealth tools. To maximize effects of such tools, it is imperative to tailor information to a priori identified survivor subgroups and increase engagement efforts.

A user centered design approach to development of an online self-management program for cancer survivors: Springboard Beyond Cancer.

OBJECTIVE: The American Cancer Society and the National Cancer Institute launched and evaluated a personalized online program leveraging behavioral science principles to help people self-manage physical and emotional symptoms, improve communication skills, and lead healthier lives during and after a cancer diagnosis. METHODS: Cancer survivors were recruited from an academic medical and a community clinical setting (N = 40) to complete in-person user testing of the Springboard Beyond Cancer website, which included action decks and content to promote self-management. Action decks were printable or savable collections of information and action steps related to a cancer topic or treatment side effect. Participants performed structured tasks to evaluate the program's content and usability. Comments and reactions were recorded, and qualitative thematic analyses were conducted. RESULTS: Most participants successfully found information about fatigue (95%), pain (83%), sexual side effects (90%), and support groups (85%). Survivors, particularly those in treatment, found information on the site to be clear, concise, and meeting their needs. Use of action decks to create self-management plans was inconsistent. Survivors reported needing more instruction and support within the program on how to best utilize enhanced functionality in action decks to prioritize their most pressing concerns. CONCLUSIONS: Early stakeholder engagement throughout the multiple phases of prototyping and deployment are needed to fully maximize end user engagement. Providing actionable self-management content and activating tools to cancer survivors via an eHealth program is a feasible and scalable approach to increasing access to self-management tools and addressing cancer survivor needs.

Disentangling Efficacy and Expectations: A Prospective, Cross-lagged Panel Study of Cancer Survivors' Physical Activity.

Background: Despite demonstrated utility of Bandura's social cognitive theory for increasing physical activity among cancer survivors, the validity of the originally hypothesized relationships among self-efficacy, outcome expectations, and physical activity behavior continues to be debated. Purpose: To explore the temporal ordering of outcome expectations and self-efficacy as they relate to moderate-to-vigorous physical activity behavior. Methods: Longitudinal data from cancer survivors (N = 1,009) recently completing treatment were used to fit six cross-lagged panel models, including one parent model, one model representing originally hypothesized variable relationships, and four alternative models. All models contained covariates and used full information maximum likelihood and weighted least squares mean and variance adjusted estimation. Tests of equal fit between the parent model and alternative models were conducted. Results: The model depicting Bandura's originally hypothesized relationships showed no statistically significant relationship between outcome expectations and physical activity (p = .18), and was a worse fit to the data, compared with the parent model [Χ2 (1) = 5.92, p = .01]. An alternative model showed evidence of a reciprocal relationship between self-efficacy and outcome expectations, and was statistically equivalent to the parent model [Χ2(1) = 2.01, p = .16]. Conclusions: This study provides evidence against Bandura's theoretical assertions that (a) self-efficacy causes outcome expectations and not vice versa, and (b) outcome expectation has a direct effect on physical activity. Replication within population subgroups and for other health behaviors will determine whether the social cognitive theory needs modification. Future trials should test whether differential construct ordering results in clinically meaningful differences in physical activity behavior change.

Evaluation of Colorectal Cancer Screening in Federally Qualified Health Centers.

INTRODUCTION: Screening for colorectal cancer in average-risk adults is recommended beginning at age 50 years and continuing until age 75 years. This study was conducted to provide evidence for the effectiveness of an American Cancer Society grant program promoting colorectal cancer screening by implementing evidence-based interventions proven to increase screening rates. METHODS: Analysis compared colorectal cancer screening rates in 77 grant-funded federally qualified health centers between 2013 and 2015 to those of a sample of 77 nonfunded federally qualified health centers selected using a genetic matching technique. The Uniform Data System from 2013 to 2015 provided data used in the analysis performed in 2016. RESULTS: Funded grantees differed significantly from nongrantees on several indicators at baseline. Genetic matching resulted in good-quality matched samples. Both matched samples increased colorectal cancer screening rates over time. Grantees increased their colorectal cancer screening rates significantly more than nongrantees, especially between 2013 and 2014, where funded federally qualified health centers increased by 9% and nonfunded federally qualified health centers increased by 3%. Across the 3 years, increases were 12% and 9%, respectively. CONCLUSIONS: The findings suggest grant funding was effective in promoting improvements in colorectal cancer screening rates in funded federally qualified health centers, and these improvements exceed those of nonfunded federally qualified health centers. Funding that results in targeted, intensive efforts supported by technical assistance and accountability for data and reporting, can result in improved system policies and practices that, in turn, can increase screening rates among uninsured and underserved populations.

Reduced Prevalence of Obesity in 14 Disadvantaged Black Communities in the United States: A Successful 4-Year Place-Based Participatory Intervention.

OBJECTIVES: To assess the impact of a large-scale place-based intervention on obesity prevalence in Black communities. METHODS: The Racial and Ethnic Approaches to Community Health across the United States (REACH US) project was conducted in 14 predominantly Black communities in California, Illinois, Massachusetts, New York, Ohio, Pennsylvania, South Carolina, Virginia, Washington, and West Virginia. We measured trends from 2009 to 2012 in the prevalence of obesity. We used Behavioral Risk Factor Surveillance System data to compare these trends with trends among non-Hispanic Whites and non-Hispanic Blacks in the United States and in the 10 states where REACH communities were located, and with a propensity score-matched national sample of non-Hispanic Blacks. RESULTS: The age-standardized prevalence of obesity decreased in REACH US communities (P = .045), but not in the comparison populations (P = .435 to P = .996). The relative change was -5.3% in REACH US communities versus +2.4% in propensity score-matched controls (P value for the difference = .031). The net effect on the reduction of obesity prevalence was about 1 percentage point per year for REACH. CONCLUSIONS: Obesity prevalence was reduced in 14 disadvantaged Black communities that participated in the REACH project.

Predicting Positive Education Outcomes for Emerging Adults in Mental Health Systems of Care.

Emerging adults who receive services based on positive youth development models have shown an ability to shape their own life course to achieve positive goals. This paper reports secondary data analysis from the Longitudinal Child and Family Outcome Study including 248 culturally diverse youth ages 17 through 22 receiving mental health services in systems of care. After 12 months of services, school performance was positively related to youth ratings of school functioning and service participation and satisfaction. Regression analysis revealed ratings of young peoples' perceptions of school functioning, and their experience in services added to the significant prediction of satisfactory school performance, even controlling for sex and attendance. Finally, in addition to expected predictors, participation in planning their own services significantly predicted enrollment in higher education for those who finished high school. Findings suggest that programs and practices based on positive youth development approaches can improve educational outcomes for emerging adults.

Relationship between child care centers' compliance with physical activity regulations and children's physical activity, New York City, 2010.

INTRODUCTION: Physical activity may protect against overweight and obesity among preschoolers, and the policies and characteristics of group child care centers influence the physical activity levels of children who attend them. We examined whether children in New York City group child care centers that are compliant with the city's regulations on child physical activity engage in more activity than children in centers who do not comply. METHODS: A sample of 1,352 children (mean age, 3.39 years) served by 110 group child care centers in low-income neighborhoods participated. Children's anthropometric data were collected and accelerometers were used to measure duration and intensity of physical activity. Multilevel generalized linear regression modeling techniques were used to assess the effect of center- and child-level factors on child-level physical activity. RESULTS: Centers' compliance with the regulation of obtaining at least 60 minutes of total physical activity per day was positively associated with children's levels of moderate to vigorous physical activity (MVPA); compliance with the regulation of obtaining at least 30 minutes of structured activity was not associated with increased levels of MVPA. Children in centers with a dedicated outdoor play space available also spent more time in MVPA. Boys spent more time in MVPA than girls, and non-Hispanic black children spent more time in MVPA than Hispanic children. CONCLUSION: To increase children's level of MVPA in child care, both time and type of activity should be considered. Further examination of the role of play space availability and its effect on opportunities for engaging in physical activity is needed.

Evaluation design of New York City's regulations on nutrition, physical activity, and screen time in early child care centers.

This article describes the multi-method cross-sectional design used to evaluate New York City Department of Health and Mental Hygiene's regulations of nutrition, physical activity, and screen time for children aged 3 years or older in licensed group child care centers. The Center Evaluation Component collected data from a stratified random sample of 176 licensed group child care centers in New York City. Compliance with the regulations was measured through a review of center records, a facility inventory, and interviews of center directors, lead teachers, and food service staff. The Classroom Evaluation Component included an observational and biometric study of a sample of approximately 1,400 children aged 3 or 4 years attending 110 child care centers and was designed to complement the center component at the classroom and child level. The study methodology detailed in this paper may aid researchers in designing policy evaluation studies that can inform other jurisdictions considering similar policies.

Measurement of compliance with New York City's regulations on beverages, physical activity, and screen time in early child care centers.

INTRODUCTION: Policy interventions designed to change the nutrition environment and increase physical activity in child care centers are becoming more common, but an understanding of the implementation of these interventions is yet to be developed. The objective of this study was to explore the extent and consistency of compliance with a policy intervention designed to promote nutrition and physical activity among licensed child care centers in New York City. METHODS: We used a multimethod cross-sectional approach and 2 independent components of data collection (Center Evaluation Component and Classroom Evaluation Component). The methods were designed to evaluate the impact of regulations on beverages served, physical activity, and screen time at child care centers. We calculated compliance scores for each evaluation component and each regulation and percentage agreement between compliance in the center and classroom components. RESULTS: Compliance with certain requirements of the beverage regulations was high and fairly consistent between components, whereas compliance with the physical activity regulation varied according to the data collection component. Compliance with the regulation on amount and content of screen time was high and consistent. CONCLUSION: Compliance with the physical activity regulation may be a more fluid, day-to-day issue, whereas compliance with the regulations on beverages and television viewing may be easier to control at the center level. Multiple indicators over multiple time points may provide a more complete picture of compliance - especially in the assessment of compliance with physical activity policies.

PKCγ receptor mediates visceral nociception and hyperalgesia following exposure to PTSD-like stress in the spinal cord of rats.

BACKGROUND: Clinical studies indicate that patients with post-traumatic stress disorder (PTSD) frequently share comorbidity with numerous chronic pain conditions. However, the sustained effects of PTSD-like stress over time on visceral nociception and hyperalgesia have been rarely studied, and the underlying mechanisms of stress-induced modulation of visceral hyperalgesia remain elusive. The purpose of this study was to investigate the characterization of visceral nociception and hyperalgesia over time in rats exposed to PTSD-like stress, and to explore the potential role of protein kinase C gamma (PKCγ) in mediating visceral hyperalgesia following exposure to PTSD-like stress. RESULTS: On day 1, the rats exposed to single-prolonged stress (SPS, an established animal model for PTSD) exhibited an analgesic response and its visceromotor response (VMR) to graded colorectal distention (CRD) at 40 and 60 mmHg was reduced compared with the control group (all P < 0.05). On day 6, the VMR returned to the baseline value. However, as early as 7 days after SPS, VMR dramatically increased compared with its baseline value and that in the controls (all P < 0.001) and this increase persisted for 28 days, with the peak on day 9. Abdominal withdrawal reflex (AWR) scores were higher in SPS rats than in controls on days 7, 9, 14, 21 and 28 (all P < 0.001). Intrathecal administration of GF109203X (an inhibitor of PKC gamma), attenuated the SPS-induced increase in both VMR and AWR scores on days 7, 14, 21 and 28 (all P < 0.05). PKCγ protein expression determined by immunofluorescence was reduced in the spinal cord within 3 days after the exposure to SPS (P < 0.01), which returned to normal levels between days 4 and 6, and significantly increased from day 7, and this increase was maintained on days 14, 21, and 28 (all P < 0.001), with the peak on day 9. In addition, Western blotting showed a consistent trend in the changes of PKCγ protein expression. CONCLUSIONS: The modified SPS alters visceral sensitivity to CRD, and contributes to the maintenance of visceral hyperalgesia, which is associated with enhanced PKCγ expression in the spinal cord. Functional blockade of the PKCγ receptors attenuates SPS-induced visceral hyperalgesia. Thus, the present study identifies a specific molecular mechanism for visceral hyperalgesia which may pave the way for novel therapeutic strategies for PTSD-like conditions.

Characterization of the Visceral Antinociceptive Effect of Glial Glutamate Transporter GLT-1 Upregulation by Ceftriaxone.

Recent studies demonstrate that glial glutamate transporter-1 (GLT-1) upregulation attenuates visceral nociception. The present work further characterized the effect of ceftriaxone- (CTX-) mediated GLT-1 upregulation on visceral hyperalgesia. Intrathecal pretreatment with dihydrokainate, a selective GLT-1 antagonist, produced a reversal of the antinociceptive response to bladder distension produced by CTX. The hyperalgesic response to urinary bladder distension caused by intravesicular acrolein was also attenuated by CTX treatment as was the enhanced time spent licking of abdominal area due to intravesicular acrolein. Bladder inflammation via cyclophosphamide injections enhanced the nociceptive to bladder distension; cohorts administered CTX and concomitant cyclophosphamide showed reduced hyperalgesic response. Cyclophosphamide-induced bladder hyperalgesia correlated with a significant 22% increase in GluR1 AMPA receptor subunit expression in the membrane fraction of the lumbosacral spinal cord, which was attenuated by CTX coadministration. Finally, neonatal colon insult-induced hyperalgesia caused by intracolonic mustard oil (2%) administration at P9 and P11 was attenuated by CTX. These studies suggest that GLT-1 upregulation (1) attenuates the hyperalgesia caused by bladder irritation/inflammation or by neonatal colonic insult, (2) acts at a spinal site, and (3) may produce antinociceptive effects by attenuating GluR1 membrane trafficking. These findings support further consideration of this FDA-approved drug to treat chronic pelvic pain syndromes.

Peripheral nervous system neuropathology and progressive sensory impairments in a mouse model of Mucopolysaccharidosis IIIB.

The lysosomal storage pathology in Mucopolysaccharidosis (MPS) IIIB manifests in cells of virtually all organs. However, it is the profound role of the neurological pathology that leads to morbidity and mortality in this disease, and has been the major challenge to developing therapies. To date, MPS IIIB neuropathologic and therapeutic studies have focused predominantly on changes in the central nervous system (CNS), especially in the brain, and little is known about the disease pathology in the peripheral nervous system (PNS). This study demonstrates characteristic lysosomal storage pathology in dorsal root ganglia affecting neurons, satellite cells (glia) and Schwann cells. Lysosomal storage lesions were also observed in the myoenteric plexus and submucosal plexus, involving enteric neurons with enteric glial activation. Further, MPS IIIB mice developed progressive impairments in sensory functions, with significantly reduced response to pain stimulation that became detectable at 4-5 months of age as the disease progressed. These data demonstrate that MPS IIIB neuropathology manifests not only in the entire CNS but also the PNS, likely affecting both afferent and efferent neural signal transduction. This study also suggests that therapeutic development for MPS IIIB may benefit from targeting the entire nervous system.

Referral patterns for youths identified at risk for suicide by trained gatekeepers.

BACKGROUND: In order to better understand the posttraining suicide prevention behavior of gatekeeper trainees, the present article examines the referral and service receipt patterns among gatekeeper-identified youths. METHODS: Data for this study were drawn from 26 Garrett Lee Smith grantees funded between October 2005 and October 2009 who submitted data about the number, characteristics, and service access of identified youths. RESULTS: The demographic characteristics of identified youths are not related to referral type or receipt. Furthermore, referral setting does not seem to be predictive of the type of referral. Demographic as well as other (nonrisk) characteristics of the youths are not key variables in determining identification or service receipt. LIMITATIONS: These data are not necessarily representative of all youths identified by gatekeepers represented in the dataset. The prevalence of risk among all members of the communities from which these data are drawn is unknown. Furthermore, these data likely disproportionately represent gatekeepers associated with systems that effectively track gatekeepers and youths. CONCLUSIONS: Gatekeepers appear to be identifying youth across settings, and those youths are being referred for services without regard for race and gender or the settings in which they are identified. Furthermore, youths that may be at highest risk may be more likely to receive those services.

Gender differences in patterns of child risk across programmatic phases of the CMHI: a multiple group latent class analysis (LCA).

Data from 18,437 children enrolled in the national evaluation of the Children's Mental Health Initiative between 1994 and 2005 were used to examine the evolution of patterns of risk among boys and girls across funding phases using multigroup latent class analysis. Consistent with previous research, this study identified four subgroups of children with similar patterns of child risk. Membership to these risk subgroups varied as a function of age and was associated with differences in impairment levels. Changes in the distribution of boys and girls in the risk classes suggest that, over time, an increasing proportion of boys have entered the system of care program with complex histories of risk. Information on children's exposure to child risk factors can aid policy makers, service providers, and clinicians in identifying children who may need more intensive services and tailoring services to their needs.

Glutamate transporter activators as anti-nociceptive agents.

The effective management of chronic pain remains enigmatic. There is a paucity of effective mechanistically-based approaches employed. Chronic visceral pain is a particularly difficult subcategory to manage. Glutamate is the most predominant excitatory neurotransmitter and mediates many aspects of sensory function including acute and chronic pain. There is a growing literature describing the efficacy of physiologically dominant glutamate transporter GLT-1 up-regulation in attenuating chronic visceral and somatic nociception. Since glutamate is the major excitatory neurotransmitter released in the first central synapse of the pain-transmitting afferent neurons, augmentation of GLT-1 activity, which reduces extracellular levels of glutamate, may be an important target for pain management strategies. This review summarizes studies in our laboratory and others which highlight findings that GLT-1 up-regulation by transgenic, pharmacologic and viral transfection approaches attenuate a host of nociceptive responses emanating from visceral or somatic sources in animal models. The study also outlines the future work that will be required to ascertain the translational potential of this approach.

Testing the effects of a decision aid for prostate cancer screening.

There is an ever-growing trend toward more patient involvement in making health care decisions. This trend has been accompanied by the development of "informed decision-making" interventions to help patients become more engaged and comfortable with making these decisions. We describe the effects of a prostate cancer screening decision aid on knowledge, beliefs about screening, risk perception, control preferences, decisional conflict, and decisional anxiety. Data were collected from 200 males aged 50-70 years in the general population who randomly were assigned to exposure to the decision aid or no exposure as a control condition. A Solomon four-group design was used to test for possible pretest sensitization effects and to assess the effects of exposure to the decision aid. No significant pretest sensitization effects were found. Analysis of the exposure effects found that knowledge increased significantly for those exposed to the decision aid compared with those unexposed. Exposure to the decision aid also had some influence on decreasing both decisional conflict and decisional anxiety. Decision aids can play an important role in increasing patients' knowledge and decreasing anxiety when asked to make health care decisions.

Patterns of functional impairment and their change among youth served in systems of care: an application of latent transition analysis.

This study describes patterns of youth functioning at intake and 6 months into services in systems of care and change in functioning profiles. Participants included 2,826 males and 1,335 females aged 5 to 18 at intake. Functional impairment was assessed at intake and 6 months. Latent class analysis was used to classify youth based on their functional impairment profiles, and latent class transition analysis was used to examine the conditional probabilities of transitions in class membership between intake and 6 months. Males and females enter services with distinct patterns of functional impairment. The majority of youth remained in their respective profiles. Transitions tended to be from a higher to a lower impairment class. Importantly, a small group of males and females transitioned from a low to a higher impairment class. Providers should note that gender differences existed in the nature of change in class membership over time.

Increased glial glutamate transporter EAAT2 expression reduces visceral nociceptive response in mice.

Visceral hypersensitivity is the leading complaint of functional bowel disorders. Central sensitization mediated by glutamate receptor activation is implicated in pathophysiology of visceral pain. The glial glutamate transporter EAAT2 is the principal mediator of glutamate clearance to terminate glutamate-mediated responses. Transgenic mice overexpressing human EAAT2 (EAAT2 mice), which exhibited a twofold enhanced glutamate uptake, showed 39% less writhing response to intraperitoneal acetic acid than nontransgenic littermates. Moreover, EAAT2 transgenic mice showed a 53-64% reduction in visceromotor response (VMR) to colorectal distension (CRD) in assessments of the response to graded increase in pressures. Corroborating the involvement of enhanced glutamate uptake, wild-type mice treated for 1 wk with ceftriaxone, an EAAT2 expression activator, showed a 49-70% reduction in VMR to CRD. Moreover, systemic pretreatment with the selective EAAT2 transporter blocker dihydrokainate reversed the ceftriaxone-blunted nociceptive response to CRD. However, the enhanced VMR to CRD produced by intracolonic ethanol was not significantly attenuated by 1-wk ceftriaxone pretreatment. The data suggest that enhanced glutamate uptake provides protective effects against colonic distension-induced nociception and represents an exciting new mechanistic approach leading to better therapeutic options to visceral pain disorders.
