Prevalence and predictors of depression, pain, and fatigue in older- versus younger-adult cancer survivors.

BACKGROUND: As the number of older adults in the United States continues to grow, there will be increasing demands on health care providers to address the needs of this population. Cancer is of particular importance, with over half of all cancer survivors older than 65 years. In addition, depression, pain, and fatigue are concerns for older adults with cancer and have been linked to poorer physical outcomes. METHODS: For this retrospective chart review, 1012 eligible participants were identified via a query of the Electronic Medical Record for all patients referred to 1 of 4 Survivorship Clinics at Memorial Sloan Kettering Cancer Center. All patients were between the ages of 30 to 55 (younger adults) and >65 (older adults). Depression was measured using the Patient Health Questionnaire-9 (PHQ-9). RESULTS: The overall rate of depression in this sample of adult cancer survivors was 9.3%. There were no differences in the rates of clinically significant depression (defined as PHQ-9 score ≥10) between younger and older adult cohorts. However, there was a small trend toward higher mean PHQ-9 scores in the younger adult cohort (3.42 vs 2.95; t = 1.763, P = .10). Women reported greater rates of depression and higher pain and fatigue scores. Hispanic/Latino patients also reported significantly greater rates of depression. CONCLUSION: There were no observed differences in depression between older and younger adult cancer survivors. Gender and ethnic discrepancies in depression were observed. Future research should focus on understanding the nature of these differences and targeting interventions for the groups most vulnerable to depression after cancer treatment.

Role of surface electromagnetic waves in metamaterial absorbers.

Metamaterial absorbers have been demonstrated across much of the electromagnetic spectrum and exhibit both broad and narrow-band absorption for normally incident radiation. Absorption diminishes for increasing angles of incidence and transverse electric polarization falls off much more rapidly than transverse magnetic. We unambiguously demonstrate that broad-angle TM behavior cannot be associated with periodicity, but rather is due to coupling with a surface electromagnetic mode that is both supported by, and well described via the effective optical constants of the metamaterial where we achieve a resonant wavelength that is 19.1 times larger than the unit cell. Experimental results are supported by simulations and we highlight the potential to modify the angular response of absorbers by tailoring the surface wave.

Assessing anxiety in Black men with prostate cancer: further data on the reliability and validity of the Memorial Anxiety Scale for Prostate Cancer (MAX-PC).

PURPOSE: The National Cancer Institute has highlighted the need for psychosocial research to focus on Black cancer patients. This applies to Black men with prostate cancer, as there is little systematic research concerning psychological distress in these men. This study was designed to validate the Memorial Anxiety Scale for Prostate Cancer (MAX-PC) in Black men with prostate cancer to help facilitate research within this group. METHODS: At three institutions, Black men with prostate cancer (n = 101) completed the MAX-PC, the Hospital Anxiety and Depression Scale (HADS), the Functional Assessment of Cancer Therapy (FACT) Quality of Life Questionnaire, and the Distress Thermometer. RESULTS: The average age of the 101 men was 66 (SD = 10) and 58 % had early-stage disease. The MAX-PC and its subscales (Prostate Cancer Anxiety, PSA Anxiety, and Fear of Recurrence) produced strong coefficient alphas (0.89, 0.88, 0.71, and 0.77, respectively). Factor analysis supported the three-factor structure of the scale established in earlier findings. The MAX-PC also demonstrated strong validity. MAX-PC total scores correlated highly with the Anxiety subscale of the HADS (r = 0.59, p < 0.01) and the FACT Emotional Well-Being subscale (r = -0.55, p < 0.01). Demonstrating discriminant validity, the correlation with the HADS Depression subscale (r = 0.40, p < 0.01) and the CES-D (r = 0.42, p < 0.01) was lower compared to that with the HADS Anxiety subscale. CONCLUSIONS: The MAX-PC is valid and reliable in Black men with prostate cancer. We hope the validation of this scale in Black men will help facilitate psychosocial research in this group that is disproportionately adversely affected by this cancer.

Optimism and barriers to colonoscopy in low-income Latinos at average risk for colorectal cancer.

OBJECTIVES: Colorectal cancer (CRC) screening continues to be underused, particularly by Latinos. CRC and colonoscopy fear, worry, and fatalism have been identified as screening barriers in Latinos. The study purpose was to examine the relationship of optimism, fatalism, worry, and fear in the context of Latinos referred for CRC screening. METHODS: Our sample included 251 Latinos between the ages of 50 and 83 years who had no personal or immediate family history of CRC, no personal history of gastrointestinal disorder, no colonoscopy in the past 5 years, and received a referral for a colonoscopy. Face-to-face interviews were performed, and data were analyzed using regression models. RESULTS: Greater optimism (ß = -1.72, p < 0.000), lower fatalism (ß = 0.29, p < 0.01), and absence of family history of cancer (ß = 1, p < 0.01) were associated with decreased worry about the colonoscopy. Being female (ß = 0.85, p < 0.05) and born in the USA (ß = 1.1, p < 0.01) were associated with greater worry about colonoscopy and the possibility of having CRC. Family history of cancer (ß = 2.6, p < 0.01), female gender (ß = 2.9, p < 0.000), not following the doctor's advice (ß = 2.7, p < 0.01), and putting off medical problems (ß = 1.9, p < 0.05) were associated with greater fear. In the multiple regression model, lower optimism (ß = -0.09, p < 0.05), higher fatalism (ß = 0.28, p < 0.01), and female gender (ß = 0.9, p < 0.05) were associated with greater worry. CONCLUSIONS: Interventions that address fatalism and promote optimistic beliefs may reduce worry among Latinos referred for colonoscopy. Interventions that alleviate colonoscopy fear because of family history of cancer particularly among Latino women may help improve distress about CRC screening.

Psychological correlates of sexual dysfunction in female rectal and anal cancer survivors: analysis of baseline intervention data.

INTRODUCTION: Sexual dysfunction represents a complex and multifactorial construct that can affect both men and women and has been noted to often deteriorate significantly after treatment for rectal and anal cancer. Despite this, it remains an understudied, underreported, and undertreated issue in the field of cancer survivorship. AIM: This study examined the characteristics of women enrolled in an intervention trial to treat sexual dysfunction, and explored the relationship between sexual functioning and psychological well-being. METHODS: There were 70 female posttreatment anal or rectal cancer survivors assessed as part of the current study. Participants were enrolled in a randomized intervention trial to treat sexual dysfunction and completed outcome measures prior to randomization. MAIN OUTCOMES MEASURES: The main outcome measures are quality of life (QOL) (European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire [EORTC-QLQ-C30] and Colorectal Cancer-Specific Module [QLQ-CR38]), sexual functioning (Female Sexual Functioning Index), and psychological well-being (Brief Symptom Inventory Depression/Anxiety, Impact of Events Scale-Revised, CR-38 Body Image). RESULTS: Women enrolled in the study intervention were on average 55 years old, predominantly Caucasian (79%), married (57%), and a median of 4 years postprimary treatment. For those reporting sexual activity at baseline (N=41), sexual dysfunction was associated with a range of specific measures of psychological well-being, all in the hypothesized direction. The Sexual/Relationship Satisfaction subscale was associated with all measures of psychological well-being (r=-0.45 to -0.70, all P<0.01). Body image, anxiety, and cancer-specific posttraumatic distress were notable in their association with subscales of sexual functioning, while a global QOL measure was largely unrelated. CONCLUSIONS: For sexually active female rectal and anal cancer survivors enrolled in a sexual health intervention, sexual dysfunction was significantly and consistently associated with specific measures of psychological well-being, most notably Sexual/Relationship Satisfaction. These results suggest that sexual functioning may require focused assessment by providers, beyond broad QOL assessments, and that attention to Sexual/Relationship Satisfaction may be critical in the development and implementation of interventions for this cohort of patients.

Frequency, characteristics, and correlates of pain in a pilot study of colorectal cancer survivors 1-10 years post-treatment.

OBJECTIVE: The long-term effects of disease and treatment in colorectal cancer (CRC) survivors are poorly understood. This study examined the prevalence and characteristics of pain in a sample of CRC survivors up to 10 years post-treatment. DESIGN: One hundred cancer-free CRC survivors were randomly chosen from an institutional database and completed a telephone survey using the Brief Pain Inventory, Neuropathic Pain Questionnaire-Short Form, Quality of Life Cancer Survivor Summary, Brief Zung Self-Rating Depression Scale, Zung Self-Rating Anxiety Scale, and Fear of Recurrence Questionnaire. RESULTS: Participants were primarily Caucasian (90%) married (69%) males (53.5%) with a mean age of 64.7 years. Chronic pain was reported in 23% of CRC survivors, with a mean moderate intensity rating (mean = 6.05, standard deviation = 2.66) on a 0-10 rating scale. Over one-third (39%) of those with pain attributed it to their cancer or treatment. Chi-square and t-test analyses showed that survivors with pain were more likely to be female, have lower income, be more depressed and more anxious, and show a higher endorsement of suicidal ideation than CRC survivors without chronic pain. On average, pain moderately interfered with daily activity. CONCLUSIONS: Chronic pain is likely a burdensome problem for a small but not inconsequential minority of CRC survivors requiring a biopsychosocial treatment approach to improve recognition and treatment. Open dialogue between clinicians and survivors about physical and emotional symptoms in long-term follow-up is highly recommended.

Men's experience with sexual dysfunction post-rectal cancer treatment: a qualitative study.

In an effort to address reports from men that their sex life is worse after treatment for rectal cancer, this qualitative study was designed to better understand their experience with sexual dysfunction following rectal cancer treatment, thus providing information on the adaptation of a psycho-educational sexual health intervention for male rectal cancer survivors and simultaneously investigating barriers and promoters that would influence their participation in a psycho-educational sexual health intervention. Thirteen male rectal cancer survivors who were treated at Memorial Sloan-Kettering Cancer Center (MSKCC) for rectal cancer participated (median time post-treatment was 6.4 years). Six survivors participated in individual semi-structured phone interviews, and seven others took part in focus groups. We performed standard procedures of qualitative thematic text analysis, which involved independent review of interview and focus group transcripts by several analysts followed by consensus meetings to identify key themes. Participants reported bowel dysfunction (N = 13, or 100%) and erectile dysfunction (N = 12, or 92%) as chief complaints. The participants thought a psychoeducational sexual health intervention post-surgery would be helpful because it would provide educational information regarding the etiology of their problems and treatments to improve their sexual health (N = 8, or 62%). Most participants' primary concern immediately after treatment was surviving their disease; improving sexual functioning seemed to become more important over time. Barriers to potentially participating in a psycho-educational sexual health intervention included geographical distance from MSKCC (N = 3, or 3/13) and the risk of embarrassment when discussing sexual issues (N = 5, or 5/13). Men reported that a psycho-educational sexual health intervention would be helpful to improve their sexual functioning post-treatment. Discussion of bowel issues and logistical concerns gave information on the psycho-educational sexual health intervention.

Taming the blackbody with infrared metamaterials as selective thermal emitters.

In this Letter we demonstrate, for the first time, selective thermal emitters based on metamaterial perfect absorbers. We experimentally realize a narrow band midinfrared (MIR) thermal emitter. Multiple metamaterial sublattices further permit construction of a dual-band MIR emitter. By performing both emissivity and absorptivity measurements, we find that emissivity and absorptivity agree very well as predicted by Kirchhoff's law of thermal radiation. Our results directly demonstrate the great flexibility of metamaterials for tailoring blackbody emission.

Screening for abuse risk in pain patients.

As opioid prescribing has dramatically expanded over the past decade, so too has the problem of prescription drug abuse. In response to these now two major public health problems - the problem of poorly treated chronic pain and the problem of opioid abuse - a new paradigm has arisen in pain management, namely risk stratification. Once a prescriber has determined that opioids will be used (a medical decision based on how intense the pain is, what has been tried and failed and, to some extent, what type of pain the patient has), he/she must then decide how opioid therapy is to be delivered. Different models of delivery of opioid therapy can be utilized, beginning the process with a risk assessment that is highly individualized to each patient. Recently, researchers have produced a wide variety of literature regarding assessment tools to be used for this purpose. And while there remains a need for larger prospective studies to examine the ability of each tool to predict aberrant drug-taking behaviors, clinicians can and should utilize one or more of these screening tools and understand their benefits and limitations. This chapter will describe the nature of current screening assessments, their potential for use in the pain population in various settings, past clinical observations and suggestions for moving forward.

Infrared spatial and frequency selective metamaterial with near-unity absorbance.

We demonstrate, for the first time, a spatially dependent metamaterial perfect absorber operating in the infrared regime. We achieve an experimental absorption of 97% at a wavelength of 6.0   µm, and our results agree well with numerical full-wave simulations. By using two different metamaterial sublattices we experimentally demonstrate a spatial and frequency varying absorption which may have many relevant applications, including hyperspectral subsampling imaging.

Substance abuse in cancer pain.

In the oncology community, opioids recently have become the cornerstone of cancer pain management. This has led to a rapid increase in opioid prescribing in an effort to address the growing public health problem of chronic pain. A new paradigm in noncancer pain management has emerged, that of risk assessment and stratification in opioid therapy. Techniques foreign to cancer pain management have now become commonplace in the noncancer pain setting, such as the use of monitoring compliance via urine drug screens. Amidst these strides in opioid use for pain management, cancer has been changing. The survival rate has increased, and a group of these patients with chronic pain were treated with opioid therapy. With opioid exposure being longer and against the backdrop of prescription drug abuse, the question is how much of the adaptation of the risk management paradigm in chronic pain management is to be imported to cancer pain management?

The sexual health of female rectal and anal cancer survivors: results of a pilot randomized psycho-educational intervention trial.

BACKGROUND: Sexual dysfunction is a frequently reported consequence of rectal/anal cancer treatment for female patients. PURPOSE: The purpose of this study was to conduct a small randomized controlled trial to assess the efficacy of a telephone-based, four-session Cancer Survivorship Intervention-Sexual Health (CSI-SH). METHODS: Participants (N = 70) were stratified by chemotherapy, stoma, and menopause statuses before randomization to CSI-SH or assessment only (AO). Participants were assessed at baseline, 4 months (follow-up 1), and 8 months (follow-up 2). RESULTS: The intervention had medium effect sizes from baseline to follow-up 1, which decreased by follow-up 2. Effect sizes were larger among the 41 sexually active women. Unadjusted means at the follow-ups were not significantly different between the treatment arms. Adjusting for baseline scores, demographics, and medical variables, the intervention arm had significantly better emotional functioning at follow-ups 1 and 2 and less cancer-specific stress at follow-up 1 compared to the AO arm. CONCLUSION: The data supported the hypothesized effects on improved sexual and psychological functioning and quality of life in CSI-SH female rectal/anal cancer survivors compared to the AO condition. This pilot study (N = 70) of CSI-SH supported the impact of this intervention on sexual and psychological functioning and quality of life on rectal and anal cancer survivors compared with an AO condition. However, intervention effects were stronger at follow-up 1 as compared to follow-up 2 and were stronger for sexually active women. IMPLICATIONS FOR CANCER SURVIVORS: Women may benefit from a brief, four-session, sexual health intervention after treatment from rectal and anal cancer.

Polysomnographic Study of Sleep in Survivors of Breast Cancer.

STUDY OBJECTIVE: Insomnia is a frequent complaint in breast cancer patients during and after treatment. Breast cancer survivors, 1-10 years posttreatment, underwent in-lab polysomnography (PSG) to objectively define the insomnia in those patients with such a complaint. METHODS: Twenty-six breast cancer survivors (aged 39-80, mean 54.0 months posttreatment) spent 2 nights in the sleep laboratory. Sleep on Night 2 was scored for sleep stages, sleep onset latency, REM sleep onset latency, wake time, apneas and hypopneas, periodic limb movements and arousals. Subjects were allocated into 2 groups by their scores on the Pittsburgh Sleep Quality Index (PSQI): no/ mild sleep disturbance (PSQI score ≤ 9, n = 15) or moderate/ severe sleep disturbance (PSQI ≥ 10, n = 11). RESULTS: Standard PSG/EEG parameters failed to differentiate insomniacs from non-insomniacs. The single variable that distinguished the insomnia group was periodic limb movements in sleep (PLMS). PLMS were significantly correlated (r ≅ 0.7, p < 0.02) with subjective report of insomnia on PSQI and insomnia severity index. Log[Number of PLMS] was higher in the moderate/severe insomnia group (p = 0.008). Five of 11 patients in the moderate/severe insomnia group had a PLMS index ≥ 15, compared to only one of 15 patients in the none/mild insomnia group (p = 0.02). Menopausal symptoms and use of caffeine, hypnotics, and antidepressants were unrelated to insomnia severity or PLMS. CONCLUSIONS: PLMS was the sole PSG variable that separated breast cancer survivors with moderate/severe insomnia from those with no/mild sleep disturbance. Further study of the incidence and significance of PLMS in breast cancer survivors with the complaint of insomnia is merited.

Ethnic disparities in colonoscopy use among colorectal cancer survivors: a systematic review.

PURPOSE: After curative treatment for colorectal cancer (CRC), routine colonoscopies are recommended. We aimed to identify all studies of ethnic disparities in CRC surveillance and examine any association between race/ethnicity and colonoscopy use. METHODS: We conducted a systematic literature review to address the association between race/ethnicity and colonoscopy use among CRC survivors. We searched Medline for relevant articles. Two authors reviewed titles, abstracts, and articles based on pre-determined inclusion/exclusion criteria. RESULTS: Of the 1,544 titles reviewed, eight studies published since 2001 investigated racial/ethnic disparities in colonoscopy use. Four articles showed a small significant ethnic disparity in the receipt of timely colonoscopy, and the remaining four articles showed a nonsignificant trend in the same direction. The effect did not vary by time of diagnosis or proportion of minorities in each study, though studies with larger samples showed somewhat greater racial/ethnic disparities in colonoscopy use. CONCLUSIONS: We found at least a small disparity in the use of colonoscopy among CRC survivors, suggesting that ethnic disparities continue beyond prevention, detection, and treatment of CRC. It is important to identify areas of unequal care in CRC survivorship and to promote timely surveillance among CRC survivors who belong to racial/ethnic minorities to decrease disparities in mortality. IMPLICATIONS FOR CANCER SURVIVORS: CRC survivors who belong to racial/ethnic minorities may be less likely to receive follow-up colonoscopies on time, which could contribue to higher rates of death from CRC among minorities.
