Introduction Prior studies suggest that exposure to the natural environment may impact health. The present study examines the association between objective measures of block-level greenness ...(vegetative presence) and chronic medical conditions, including cardiometabolic conditions, in a large population-based sample of Medicare beneficiaries in Miami-Dade County, Florida. Methods The sample included 249,405 Medicare beneficiaries aged ≥65 years whose location (ZIP+4) within Miami-Dade County, Florida, did not change, from 2010 to 2011. Data were obtained in 2013 and multilevel analyses conducted in 2014 to examine relationships between greenness, measured by mean Normalized Difference Vegetation Index from satellite imagery at the Census block level, and chronic health conditions in 2011, adjusting for neighborhood median household income, individual age, gender, race, and ethnicity. Results Higher greenness was significantly associated with better health, adjusting for covariates: An increase in mean block-level Normalized Difference Vegetation Index from 1 SD less to 1 SD more than the mean was associated with 49 fewer chronic conditions per 1,000 individuals, which is approximately similar to a reduction in age of the overall study population by 3 years. This same level of increase in mean Normalized Difference Vegetation Index was associated with a reduced risk of diabetes by 14%, hypertension by 13%, and hyperlipidemia by 10%. Planned post-hoc analyses revealed stronger and more consistently positive relationships between greenness and health in lower- than higher-income neighborhoods. Conclusions Greenness or vegetative presence may be effective in promoting health in older populations, particularly in poor neighborhoods, possibly due to increased time outdoors, physical activity, or stress mitigation.

Cachexia is a common complication of cancer and is associated with poor quality of life and a decrease in survival. Many patients with cancer cachexia suffer from inflammation associated with ...elevated cytokines, such as interleukin-1beta (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor (TNF). Single-agent trials to treat cancer cachexia have not led to substantial benefit as the type of cytokine which is elevated has rarely been specified and targeted. Cachexia may also be multifactorial, involving inflammation, anorexia, catabolism, depression, and pain, and targeting the multiple causes will likely be necessary to achieve improvement in weight and appetite. A PUBMED search revealed over 3000 articles on cancer cachexia in the past ten years. We attempted to review any studies related to inflammation and cancer cachexia identified by Google Scholar and PUBMED and further search for articles listed in their references. The National Comprehensive Cancer Network (NCCN) guidelines do not provide any suggestion for managing cancer cachexia except a dietary consult. A more targeted approach to developing therapies for cancer cachexia might lead to more personalized and effective therapy.

•CHOICES DA is a plain language cancer clinical trials participation decision aid targeting minority cancer patients.•CHOICES DA significantly improved knowledge and decision readiness both ...immediately and at 2-week follow-up.•Willingness to participate in trials was high at all survey time points and for all sample sub-groups.•Few significant differences in outcomes by race/ethnicity were observed.
To evaluate the impact of a web-based, plain language decision aid (CHOICES DA) on minority cancer survivors’ knowledge of cancer clinical trials (CCTs), readiness for making decisions about clinical trial participation, and willingness to participate in a clinical trial.
Participants were 64 Black and Hispanic cancer survivors from Miami, Florida. In a single arm intervention study, participants completed self-report assessments of CCT knowledge, decision readiness regarding clinical trial participation, and willingness to participate at three time points.
Black and Hispanic participants did not differ on demographic characteristics. Post-test and follow-up measures of CCT knowledge and decision readiness were significantly greater than pre-test measures for the sample overall, and for Black and Hispanic participants separately. Few significant differences were observed between Black and Hispanic participant outcomes at each survey time point, and willingness to participate did not change overall and for either group independently.
Reviewing the CHOICES DA was associated with significantly improved knowledge and decision readiness to participate in a CCT immediately and at 2-week follow-up.
These findings suggest that CHOICES DA may support informed decision making about CCT participation within an acute, yet clinically relevant window of time for minority cancer patients who are substantially under-represented in cancer research.

Rates of pregnancy among women living with HIV (WLHIV) have increased with the availability of effective HIV treatment. Planning for pregnancy and childbirth is an increasingly important element of ...HIV care. Though rates of unintended pregnancies are high among women in general, among couples affected by HIV, significant planning and reproductive decisions must be considered to prevent negative health consequences for WLHIV and their neonates. To gain insight into this reproductive decision-making process among WLHIV, this study explored women's knowledge, attitudes and practices regarding fertility planning, reproductive desires, and safer conception practices. It was hypothesized that pregnancy desires would be influenced by partners, families, the potential risk of HIV transmission to infants, and physicians' recommendations.
WLHIV of childbearing age were recruited from urban South Florida, and completed an assessment of demographics (N = 49), fertility desires and a conjoint survey of factors associated with reproductive decision-making.
Using conjoint analysis, we found that different decision paths exist for different types of women: Younger women and those with less education desired children if their partners wanted children; reproductive desires among those with less education, and with less HIV pregnancy-related knowledge, displayed a trend toward additional emphasis on their family's desires. Conversely, older women and those with more education appeared to place more importance on physician endorsement in their plans for childbearing.
Results of this study highlight the importance of ongoing preconception counselling for all women of reproductive age during routine HIV care. Counselling should be tailored to patient characteristics, and physicians should consider inclusion of families and/or partners in the process.

Background. Participation in cancer clinical trials is low, particularly in racial and ethnic minorities in some cases, which has negative consequences for the generalizability for study findings. ...The objective of this study was to determine what factors are associated with patients’ participation or willingness to participate and whether these factors vary by race/ethnicity. Design or Methods. White, Hispanic, and black participants were obtained through the Florida cancer registry and who were diagnosed with breast, lung, colorectal, or prostate cancer (N = 1100). Participants were surveyed via telephone to obtain demographic information, past participation, and willingness to participate in clinical trials, as well as barriers and facilitators to participation. Logistic and Poisson regressions were performed. Results. Respondents were on average 67.4 years old, 42.7% were male, and 50.1% were married. In this population, 7.7% of respondents had participated in a clinical trial, and 36.5% stated that they would be willing to participate. In multivariate models, blacks and Hispanics were equally likely as whites to be willing to participate in cancer trials, but Hispanics were less likely to have participated, and this was especially more likely in non–English-speaking Hispanics compared with English-speaking Hispanics. Notable barriers across race/ethnicity were mistrust and lack of knowledge of clinical trials. Limitations. Cross-sectional design limits cause-and-effect conclusions. Conclusions. There are racial differences in participation rates but not in willingness to participate. We hypothesize that willingness to participate is not very high because people are uninformed about participating, particularly in non–English-speaking Hispanics. Barriers and facilitators to participation vary by race. Improved understanding of cultural differences that can be addressed by physicians may restore faith, comprehension, and acceptability of clinical trials by all patients.

Background Nature exposures may be associated with reduced risk of heart disease. The present study examines the relationship between objective measures of neighborhood greenness (vegetative ...presence) and 4 heart disease diagnoses (acute myocardial infarction, ischemic heart disease, heart failure, and atrial fibrillation) in a population-based sample of Medicare beneficiaries. Methods and Results The sample included 249 405 Medicare beneficiaries aged 65 years and older whose location ( ZIP +4) in Miami-Dade County, Florida, did not change from 2010 to 2011. Analyses examined relationships between greenness, measured by mean block-level normalized difference vegetation index from satellite imagery, and 4 heart disease diagnoses. Hierarchical regression analyses, in a multilevel framework, assessed the relationship of greenness to each heart disease diagnosis, adjusting successively for individual sociodemographics, neighborhood income, and biological risk factors (diabetes mellitus, hypertension, and hyperlipidemia). Higher greenness was associated with reduced heart disease risk, adjusting for individual sociodemographics and neighborhood income. Compared with the lowest tertile of greenness, the highest tertile of greenness was associated with reduced odds of acute myocardial infarction by 25% (odds ratio, 0.75; 95% CI , 0.63-0.90), ischemic heart disease by 20% (odds ratio, 0.80; 95% CI , 0.77-0.83), heart failure by 16% (odds ratio, 0.84; 95% CI , 0.80-0.88), and atrial fibrillation by 6% (odds ratio, 0.94; 95% CI , 0.87-1.00). Associations were attenuated after adjusting for biological risk factors, suggesting that cardiometabolic risk factors may partly mediate the greenness to heart disease relationships. Conclusions Neighborhood greenness may be associated with reduced heart disease risk. Strategies to increase area greenness may be a future means of reducing heart disease at the population level.
•Cancer clinical trial information resources should support informed decision-making.•Feasibility, acceptability, and effectiveness of two cancer clinical trial information resources were ...examined.•Both interventions improved knowledge and clarity of opinions.•Both interventions reduced decisional conflict.•Some improvements in one intervention arm were associated with educational attainment.
To assess intervention feasibility and acceptability, and compare the effectiveness of the CHOICES Decision Aid (DA) versus the National Cancer Institute (NCI) Cancer Clinical Trials (CCT) website to improve knowledge about CCTs and preparedness to make an informed decision.
Oncology patients (n = 101) with a scheduled clinic visit were enrolled and randomized. Decision-making variables were collected at two timepoints. Post-intervention scores were examined via paired t-tests and multivariate regression analyses. Predictors of the magnitudes of the change in scores were examined in multivariable regression analyses.
The interventions were feasible to implement and acceptable to participants. Both interventions increased objective and subjective knowledge, improved clarity of opinions, and reduced decisional conflict (p-values < 0.01). Improvements in the belief that one could find out about CCTs were observed in the CHOICES DA arm (p < 0.001). Multivariable analyses controlling for educational attainment showed no significant differences in the magnitude of change in outcome variables between intervention arms, but did find that improvements in some variables in the NCI arm – but not CHOICES DA arm – were associated with previous educational attainment.
Interventions were feasible to implement and acceptable. Improvements in knowledge and decision-making outcomes were observed in both arms, supporting the view that interventions to improve CCT decision making are effective and feasible. Our results suggest that the CHOICES DA may be more effective than an informational website in improving decision-making outcomes regardless of participants’ educational attainment.
CCT resources should support informed decision-making among all cancer survivors, regardless of educational attainment.

Non-small cell lung cancer (NSCLC) is among the leading causes of cancer death in the United States. Previous studies found mixed results regarding disparities in survival by race, ethnicity, and ...socioeconomic status (SES). However, race comparisons were usually limited, with comparisons made between black and white patients only or by merging race and ethnicity together as non-Hispanic black, non-Hispanic white, and Hispanic patients. Even fewer studies included race, ethnicity, and SES together while controlling for extensive confounding variables. Thus, because we have access to a large and unique population-based database that includes tumor characteristics and patient comorbidities, the purpose of this study was to explore disparities in NSCLC survival.
We linked data from the 1996 to 2007 Florida Cancer Data System registry to the Florida's Agency for Health Care Administration and the US Census (n = 98,541). Survival time was from date of diagnosis to death or last contact. Race was white, black, Native American, Asian, Pacific Islander, Asian Indian/Pakistani, or other. Ethnicity was non-Hispanic or Hispanic. Socioeconomic status was measured as percentage of the participant's census tract living below the federal poverty line. Median survival and survival rates were calculated by Kaplan-Meier method. Cox proportional hazards regression models produced unadjusted and adjusted hazard ratios (HRs) and 95% confidence intervals (95% CIs).
The majority of patients were white (91.9%) and non-Hispanic (94.1%). Blacks had the lowest median survival (8.4 months). At 5 years after diagnosis, survival rate was highest in whites (16.3%) and lowest for Pacific Islanders (6.4%). In the adjusted model, Asians had significantly improved survival compared with whites (HR, 0.85; 95% CI, 0.76-0.95). Patients in middle-low (HR, 0.96; 95% CI, 0.94-0.99), middle-high (HR, 0.92; 95% CI, 0.89-0.94), and highest (HR, 0.87; 95% CI, 0.84-0.91) SES areas had significantly improved survival compared with those in lowest areas. Significantly worse survival was found for patients with complicated diabetes (HR, 1.05; 95% CI, 1.01-1.08), weight loss (HR, 1.08; 95% CI, 1.06-1.11), fluid and electrolyte disorders (HR, 1.08; 95% CI, 1.06-1.11), and alcohol abuse (HR, 1.11; 95% CI, 1.07-1.14).
We found strong evidence for racial and socioeconomic disparities in Floridian NSCLC survival. Asians had improved survival compared with whites, a novel finding. Our findings confirmed that patients living in lower socioeconomic neighborhoods have worse outcomes than their wealthier neighborhood counterparts. Finally, we found an association between some modifiable factors/comorbidities and worse survival. Clinicians may be able to use this information to improve patients' likelihood of better outcomes.
Background.
Cancer patients often do not make informed decisions regarding clinical trial participation. This study evaluated whether a web‐based decision aid (DA) could support trial decisions ...compared with our cancer center's website.
Methods.
Adults diagnosed with cancer in the past 6 months who had not previously participated in a cancer clinical trial were eligible. Participants were randomized to view the DA or our cancer center's website (enhanced usual care UC). Controlling for whether participants had heard of cancer clinical trials and educational attainment, multivariable linear regression examined group on knowledge, self‐efficacy for finding trial information, decisional conflict (values clarity and uncertainty), intent to participate, decision readiness, and trial perceptions.
Results.
Two hundred patients (86%) consented between May 2014 and April 2015. One hundred were randomized to each group. Surveys were completed by 87 in the DA group and 90 in the UC group. DA group participants reported clearer values regarding trial participation than UC group participants reported (least squares LS mean = 15.8 vs. 32, p < .0001) and less uncertainty (LS mean = 24.3 vs. 36.4, p = .025). The DA group had higher objective knowledge than the UC group's (LS mean = 69.8 vs. 55.8, p < .0001). There were no differences between groups in intent to participate.
Conclusions.
Improvements on key decision outcomes including knowledge, self‐efficacy, certainty about choice, and values clarity among participants who viewed the DA suggest web‐based DAs can support informed decisions about trial participation among cancer patients facing this preference‐sensitive choice. Although better informing patients before trial participation could improve retention, more work is needed to examine DA impact on enrollment and retention.
Implications for Practice:
This paper describes evidence regarding a decision tool to support patients’ decisions about trial participation. By improving knowledge, helping patients clarify preferences for participation, and facilitating conversations about trials, decision aids could lead to decisions about participation that better match patients’ preferences, promoting patient‐centered care and the ethical conduct of clinical research.

Objective
To assess the impact of the dollar value of federal low‐income housing assistance on adult health outcomes and whether this impact varies across housing assistance programs.
Data Sources
We ...use the National Health Interview Survey (NHIS) from 1999 to 2016 linked with administrative records from the Department of Housing and Urban Development (HUD) tracking receipt of low‐income housing assistance from 1999 to 2017.
Design
We use two approaches to assess the impact of the value of housing assistance among HUD housing assistance recipients on outcomes capturing overall health and mental health, chronic and acute health conditions, health care hardship, and food insecurity. First, we use multivariable regression models that adjust for a wide array of possible confounders. Second, we use an instrumental variable approach in which the county‐level supply of HUD housing serves as an instrument for the value of housing assistance.
Data Collection/Extraction Methods
Our sample includes all 12,031 adult HUD linkage‐eligible NHIS respondents who were currently in HUD housing at the time of their NHIS interview.
Principal Findings
We find the most consistent associations between the value of housing assistance and measures of health care hardship, a relationship that is most robust for Housing Choice Voucher recipients, where we find a $100 increase in the value of housing assistance is associated with a 6.2 percentage point decrease in probability of needing but not being able to afford medical care. We find little evidence that the value of housing assistance impacts overall health or chronic health outcomes.
Conclusions
The relationship between the value of housing assistance and health likely operates via an income effect, wherein receipt of a more valuable benefit frees up resources to spend on needed care. Policy changes to increase the value of housing assistance may have tangible health benefits for tenants receiving housing assistance.
