Lung cancer patient preferences indicate that EX program timing should take into account whether the patient has undergone surgery. Lung cancer survivors' EX levels declined after diagnosis and engaging in EX after treatment may improve fatigue and QoL.

Confusion and controversy exist regarding the cardiovascular effects of dietary supplements containing caffeine and Citrus aurantium (bitter orange) extract. The primary protoalkaloidal ingredient in bitter orange extract is p-synephrine which has some structural similarities to ephedrine and nor-epinehrine, but exhibits markedly different pharmacokinetic and receptor binding properties. The goal of this study was to investigate the cardiovascular effects of a product containing caffeine, bitter orange extract (p-synephrine) and green tea extract in mildly overweight individuals. Fourteen female and nine male subjects (age 24.7 ±7.4 yrs, BMI: 26.6 ±3.8) volunteered in this randomized, placebo-controlled, crossover, double-blind designed study. On day one, subjects entered the laboratory following an overnight fast. Heart rate and blood pressure were recorded at 60 min. Expired air was analyzed for the next 10 min of the session. At each of three meals, subjects ingested one capsule that was either a non-caloric placebo or a dietary supplement that contained 13 mg p-synephrine and 176 mg caffeine. On the following day, the subjects returned and repeated the protocol for data collection beginning 60 min after consuming one capsule of the placebo or the dietary supplement. No effects of the dietary supplement on heart rate, systolic and diastolic blood pressure or mean arterial pressure were observed. No between or within group differences were observed when data were analyzed for gender and caffeine usage. A small but significant decrease in resting respiratory exchange ratio was observed for the low caffeine user group in response to the product containing caffeine and p-synephrine. The results of this study indicate that ingestion of a product containing bitter orange extract, caffeine and green tea extract does not lead to increased cardiovascular stress and that fat oxidation may increase in certain populations.

With the rise in the use of the Internet for health-related purposes, social networking sites (SNSs) have become a prominent platform for cancer communication and information exchange. Studies of cancer communication on SNS have mostly focused on understanding the quantity, content, quality, and user engagement (eg, likes and comments) with cancer-related information on SNS. There is less of an understanding of when and why people coping with cancer turn to SNS for cancer-related information, and how users appraise the credibility of cancer-related information obtained on SNS. In this study, we use data from in-depth qualitative interviews with 40 primary caregivers of pediatric patients with cancer to examine how cancer caregivers engage in information appraisal and credibility assessment of cancer-related information obtained on SNS. Findings show that cancer caregivers turned to SNS for cancer-related information because information on SNS was immediate, targeted in response to specific caregiver questions and concerns, and tailored to the specific information needs of cancer caregivers. Cancer caregivers evaluated the credibility of cancer-related information obtained on SNS through assessment of the SNS user who posted the information, frequency the same information was shared, and external corroboration. Findings have important implications for cancer communication and information interventions and point to elements of SNS cancer communication that can be integrated into health professional-facilitated communication and cancer information strategies.

Background: The identification of new therapeutic targets to improve health behaviors among cancer survivors (CS) is likely to improve cancer treatment outcomes. Delay discounting (DD) rate is the degree to which one devalues rewards as a function of time to receipt. Lower DD rates (i.e., prioritizing long-term over immediate rewards) are associated with healthier behaviors. CS often experience distress and thoughts of early mortality that can potentially shift priorities to the present and negatively impact DD rates, especially when newly diagnosed. Understanding relations between DD and health behaviors among CS will contribute to the examination of DD as a therapeutic target for improving health behaviors for CS. Methods: CS (n=1,001) were recruited from a web-panel and administered a web-based questionnaire. Multivariate models examined relations among DD rate, years since diagnosis, and 10 healthy behavior indicators. We hypothesized that 1) higher DD rates would be associated with fewer years since diagnosis, and 2) lower DD rates would be associated with healthier behaviors, moderated by years since diagnosis. Results: In general, higher DD rates were associated with fewer years since diagnosis. Higher DD rates were also associated with more alcohol consumption, cigarette smoking, other tobacco use, tanning booth use, and conversely, greater adherence to annual primary care visits, but a significant interaction between DD rate and years since diagnosis was not found. Conclusions: Lower DD rates are associated with several important healthy lifestyle behaviors. DD rate is a promising therapeutic target for new interventions to improve multiple health behaviors among CS.

Traumatic brain injury (TBI) and substance use are highly prevalent conditions among military populations. There is a significant body of evidence that suggests greater approval of substance use (i.e., norms) is related to increased substance use. The objective of this work is to understand the impact of TBI and military service on substance use norms of soldiers and their partners. Data are from the baseline assessment of Operation: SAFETY, an ongoing, longitudinal study of US Army Reserve/National Guard (USAR/NG) soldiers and their partners. Multiple regression models examined associations between alcohol, tobacco, illicit drug use, and non-medical use of prescription drug (NMUPD) norms within and across partners based on current military status (CMS) and TBI. Male USAR/NG soldiers disapproved of NMUPD, illicit drug use and tobacco use. There was no relation between military status and alcohol use. Among females, there was no relation between CMS and norms. The NMUPD norms of wives were more likely to be approving if their husbands reported TBI symptoms and had separated from the military. Husbands of soldiers who separated from the military with TBI had greater approval of the use of tobacco, NMUPD, and illicit drugs. Overall, there is evidence to suggest that, while generally disapproving of substance use, soldiers and partners become more accepting of use if they also experience TBI and separate from the military. Future research should examine the longitudinal influence of TBI on substance use norms and subsequent changes in substance use over time.
