A neurotherapy protocol to remediate cognitive deficits after adjuvant chemotherapy: a pilot study.

OBJECTIVES: Adjuvant chemotherapy for breast cancer is undeniably effective in increasing survival rates but many breast cancer survivors (BCS) exhibit side effects including nausea, fatigue, stress, and neurocognitive deficits, known as "chemobrain." This pilot study explored how neurotherapy, or EEG biofeedback, a non-pharmacological approach, improved neurocognitive, behavioral, and neurophysiological deficits associated with BCS who underwent chemotherapy. METHODS: Subjects underwent 18 sessions of EEG biofeedback training, in which audio and visual feedback occurred with successful shifting of EEG patterns. RESULTS: Quantitative EEG and assessment tests demonstrated neurophysiological, cognitive, and behavioral deficits in all nine subjects prior to training. EEG biofeedback resulted in significant improvements in neurophysiological, neurocognitive, and psychological functions in all nine subjects after training. CONCLUSIONS: We propose that this intervention and related forms of EEG biofeedback have the potential to significantly alleviate common side effects of chemotherapy in BCS and therefore merits additional research attention.

Psychological Distress in Hospitalized Patients Awaiting Organ Transplantation: Case Examples, Thematic Exploration, and Suggestions for Intervention.

Organ transplantation is a life-saving mechanism with a large public health burden given the necessity of individuals to donate their organs in the event of their own death. Understanding the psychological and medical sequelae of individuals receiving an organ transplant is invaluable in a successful transplant. The waiting period for transplantation is the most psychologically difficult period, and is an important window during which to intervene psychologically and medically. Patients who are hospitalized during this waiting period make up the most vulnerable population given the psychological difficulties of not only awaiting transplant but of a prolonged and difficult hospitalization. This paper is a first step in understanding the psychological landscape of hospitalized patient's awaiting transplant and the potential research avenues and intervention strategies that may be utilized in order to decrease the psychological burden as well as influence successful medical outcomes in organ transplantation.

The father-daughter relationship in the wake of maternal death from breast cancer.

OBJECTIVES: This paper examines whether a relationship exists between paternal psychological stability and daughters' symptomatology following the death of a wife/mother from breast cancer. Specifically, is there a relationship between paternal parenting style and the daughters' subsequent capacity to form committed relationships later in life? METHODS: We assessed 68 adult daughters (average age = 23.5 years) since the mother's breast cancer diagnosis by means of a semistructured clinical interview and psychological testing. RESULTS: The daughters were subdivided into three psychiatric risk groups. Those in the highest risk group were most likely to be single and to have high CES-Depression and STAI-Anxiety scores. Daughters in the highest risk group were also most likely to have fathers who abused substances, fathers who had experienced a serious psychiatric event, and families with the most closed communication about the mother's cancer. SIGNIFICANCE OF RESULTS: Psychopathology in fathers correlated with increasing anxiety and depression in adult daughters. Daughters at the highest level of risk had the most severe affective states, the most disturbed father-daughter bonding, and the least ability to create successful interpersonal relationships as adults. We suggest specific interventions for these daughters of the lowest-functioning fathers.

Psychosocial Characteristics of Adult Daughters of Breast Cancer Patients: Comparison of Clinic and Community Caregivers Samples.

OBJECTIVE: The long-term psychosocial impact of adult daughters caring for their mothers with breast cancer has been recognized but understudied. The objectives of this study were to characterize the psychosocial functioning of women who served as informal caregivers during their mothers. treatment for breast cancer in two distinct samples, community and high risk clinic, and to determine differences in psychosocial functioning between the two samples. METHODS: Using a cross-sectional design, a sample of mostly married, Caucasian and college educated women (N = 59) were administered a battery of questionnaires assessing socio-demographic and psychosocial factors (i.e. coping, caregiving tasks and difficulty, social support, spirituality, mental distress, depressive symptoms). RESULTS: Using descriptive analysis, chi-square and T tests, results demonstrated significant differences between the two samples in time since caregiving, with the community sample reporting few years since the caregiving episode (e.g. 2.1 versus 15.1 years); coping strategies, with the clinic sample reporting higher scores on active coping, behavioral disengagement, planning, and self-blame; support type care tasks difficulty, with the clinic sample reporting higher scores on emotional support and tangible support, and all domains of spirituality (e.g. peace, meaning, faith), with higher levels being reported by the community sample. Although participants did not exhibit clinically significant levels of emotional distress, almost 25% of the community sample and 10% of the clinic sample had clinically significant depressive symptoms. CONCLUSIONS: Findings underscore the need for interventions tailored for caregivers to consider the unique psychosocial characteristics of caregivers across settings.

Predicting reattendance at a high-risk breast cancer clinic.

OBJECTIVE: The research about follow-up patterns of women attending high-risk breast-cancer clinics is sparse. This study sought to profile daughters of breast-cancer patients who are likely to return versus those unlikely to return for follow-up care in a high-risk clinic. METHOD: Our investigation included 131 patients attending the UCLA Revlon Breast Center High Risk Clinic. Predictor variables included age, computed breast-cancer risk, participants' perceived personal risk, clinically significant depressive symptomatology (CES-D score ≥ 16), current level of anxiety (State-Trait Anxiety Inventory), and survival status of participants' mothers (survived or passed away from breast cancer). RESULTS: A greater likelihood of reattendance was associated with older age (adjusted odds ratio [AOR] = 1.07, p = 0.004), computed breast-cancer risk (AOR = 1.10, p = 0.017), absence of depressive symptomatology (AOR = 0.25, p = 0.009), past psychiatric diagnosis (AOR = 3.14, p = 0.029), and maternal loss to breast cancer (AOR = 2.59, p = 0.034). Also, an interaction was found between mother's survival and perceived risk (p = 0.019), such that reattendance was associated with higher perceived risk among participants whose mothers survived (AOR = 1.04, p = 0.002), but not those whose mothers died (AOR = 0.99, p = 0.685). Furthermore, a nonlinear inverted "U" relationship was observed between state anxiety and reattendance (p = 0.037); participants with moderate anxiety were more likely to reattend than those with low or high anxiety levels. SIGNIFICANCE OF RESULTS: Demographic, medical, and psychosocial factors were found to be independently associated with reattendance to a high-risk breast-cancer clinic. Explication of the profiles of women who may or may not reattend may serve to inform the development and implementation of interventions to increase the likelihood of follow-up care.

Evolution of Emotional Symptoms Over Time Among Daughters of Patients With Breast Cancer.

OBJECTIVE: This study longitudinally profiled anxiety and depressive symptoms of daughters of patients with breast cancer and examined the mother׳s survival status, the daughter׳s age at the time of mother׳s diagnosis, and the style of family communication about breast cancer as moderators of change in symptomatology across participants׳ first 3 appointments at the University of California, Los Angeles Revlon Breast Center High Risk Clinic. METHODS: We evaluated the effects of hypothesized predictors on change in anxiety and depressive symptoms, 3 (symptomatology at first, second, and third clinic visits) × 2 (mother survived or died) × 2 (<20 or ≥20y old at diagnosis) × 2 (open or closed family communication) repeated-measures analyses of variance were employed. RESULTS: There was a main effect for time of diagnosis on state anxiety, demonstrating a significant reduction in anxiety across clinic visits overall (p < 0.001). There were also significant 3-way interactions. For state anxiety, mother׳s survival status moderated the time of diagnosis × age at diagnosis and time of diagnosis × family communication interaction effects. For daughters whose mothers died, decreased anxiety was observed in those who were younger at the time of diagnosis (p = 0.001). For daughters whose mothers survived, anxiety was decreased for those with closed family communication styles (p = 0.001). The time of diagnosis × mother׳s survival × age at diagnosis interaction was also significant for depressive symptoms (p = 0.001). Among daughters whose mothers died, those who were younger showed decreases in symptoms (p = 0.004). CONCLUSION: These daughters appeared to benefit from the high-risk program as demonstrated by decreased symptomatology, particularly daughters whose mothers died who were younger at the time of diagnosis.

A retrospective study predicting psychological vulnerability in adult daughters of breast cancer patients.

This study was an attempt to identify vulnerability factors in two cohorts of daughters of breast cancer patients. One cohort consisted of daughters whose mothers survived breast cancer and the other consisted of daughters whose mothers died from breast cancer. The results revealed significant main effects. Greater caretaking involvement was associated with higher levels of cancer-related grief. Maternal loss to breast cancer predicted higher levels of cancer-related depression. Also, a history of a depression diagnosis in the daughters was associated with current depressive symptoms. Several significant interactions also emerged. Survival status of the mother and level of daughters' involvement in mother's breast cancer was shown to significantly affect the daughters' current depressive symptoms. Daughters who reported the lowest level of involvement with their mother's breast cancer reported the highest level of current depressive symptoms. Daughters who were less than 12 years of age at the time of their mother's diagnosis reported significantly higher current state anxiety than daughters who were 12 to 19 at the time of their mother's diagnosis. Daughters whose mothers died from breast cancer, who also had a past diagnosis of depression, reported significantly higher levels of cancer-related depression than daughters without a past diagnosis of depression. We concluded that maternal death among daughters who reported very low caretaking involvement reflects the most significant vulnerability to show current depressive symptoms. We also concluded that daughters possessing potential genetic vulnerability to depression are the most sensitized to traumatic life events such as maternal illness and death.

Post-traumatic disorder symptoms and blunted diurnal cortisol production in partners of prostate cancer patients.

Prostate cancer (PC) is the most common cancer diagnosed in men, and research suggests that coping with this illness can cause significant distress in patients as well as their partners. This study examined the relationship of caregiving for a partner with PC with diurnal cortisol output in women between the ages of 42 and 75 years old. Participants were women whose partners had PC (n = 19) and women who were in relationships with men with no diagnosed medical illness (n = 26). Women provided saliva samples (4 times per day over 3 days) in their natural environment. The Structured Clinical Interview for DSM-IV Axis-I Disorders was also conducted to assess for the presence of post-traumatic stress disorder (PTSD) and major depression. Partners of men with PC had lower daily cortisol output across the three days than controls, F(1,444.08) = 20.72, p<.001). They were also more likely to report PTSD symptoms with 68.4% of PC partners fulfilling criteria for sub-threshold PTSD as compared to 23.1% of controls (χ(2) = 11.30, p = .01). Mixed model analyses revealed that the presence of sub-threshold PTSD symptoms significantly predicted cortisol production, F(1,419.64) = 5.10, p<.01). Regardless of caregiver status, women who reported at least sub-threshold PTSD symptoms had lower cortisol production than those with no PTSD symptoms. Major depression did not explain differences in cortisol production between partners of PC patients and controls. Although these findings are preliminary, they highlight the importance of developing interventions aimed at reducing risk of psychopathology in partners of men with PC.

Diurnal cortisol in Complicated and Non-Complicated Grief: slope differences across the day.

Although grief has been described primarily as a psychological phenomenon, empirical evidence reveals that grief also has physiological correlates that have consequences for health. The present study investigates the diurnal cortisol production patterns in women who have been bereaved in the past 18 months. Specifically, the study compares women with Complicated Grief (n=12) from those with Non-Complicated Grief (n=12), testing whether cortisol slope distinguishes the two groups. Results demonstrate that the two groups do not differ on demographic variables (except education), but as hypothesized, those with Complicated Grief have a flatter slope across the day, controlling for education and body mass index.

In the midnight hour: Cancer and nightmares. A review of theories and interventions in psycho-oncology.

OBJECTIVES: The purposes of this study were: (1) to explore cancer patients' complaints of poor sleep, which often involve a combination of somatic symptoms and nightmares; and (2) to understand these sleep disturbances in the light of modern dream theories and intervention modalities. METHOD: The literature search originated with several major articles (Revonsuo, 2000; Krakow & Zadra, 2006; Hobson, 2009) which then opened up the search through their references. We also used the database PubMed, and employed the following key words: cancer, nightmares/dreams, sleep disturbances, and dream theory. The literature search covered the interval between 1900 (Freud, 1900) and 2009. Our criteria for selecting studies included the most recent major review articles on the neuroscience of sleep and dreams; articles reviewing sleep disturbances in cancer patients and relevant treatments; and articles reviewing interventions for traumatic dreams. Approximately 30 articles were deemed worthy of inclusion. RESULTS: Thirty article/books/chapters met the criteria for relevance related to key theories and clinical interventions related to nightmares and traumatic dreams of cancer patients. Key concepts involve threat simulation theory and imagery rehearsal therapy in regard to theoretical and interventional paradigms significantly generalizable to cancer patients. The dream material included in this article presents patients' attempts to deal with complex threats such as intense dependency/ loss of self-sufficiency, disfigurement, and death. This is especially true with regard to the doctor-patient relationship at all stages of the illness and disease. Imagery rehearsal can facilitate empowerment in light of highly threatening and conflictual cancer-related dreams in which the patient feels helpless and victimized. SIGNIFICANCE OF RESULTS: This review offers a new lens on current dream theories and understanding of sleep disturbance in cancer patients as well as their familes and medical caregivers. Modern theories lead to opportunities for intervention that can both relieve symptoms and improve communication between medical caregivers and patients and families.

The special case of complicated grief in women at high risk for breast cancer.

OBJECTIVE: Exploration of complicated grief focusing on the relationship of post-traumatic stress disorder (PTSD) and complicated grief in a population of women at high risk for developing breast cancer. Special reference is made to women who have experienced a material death. METHOD: We reflected on the clinical attributes of the Revlon UCLA High Risk Clinic population in terms of their own perceived risk of developing breast cancer. For part of our population, their perceived risk was coupled with their reactions to the loss of their mothers to breast cancer. We compared and contrasted this pattern of reactions to those described by Licihtenthal et al. (2004) in their developmental review of complicated grief as a distinct disorder. RESULTS: We concluded that our population of women differed from Lichtenthal et al.'s (2004) model for complicated grief. Lichtenthal's group postulated that the key element of complicated grief involves the protracted nature of separation anxiety and distress and excludes PTSD. In our populations, the daughter with complicated grief experiences a combination of separation anxiety and a type of PTSD involving anxiety over the perceived certainty of her own future diagnosis of breast cancer. It was noteworthy that Lichtenthal's model population was composed of individuals caring for terminally ill spouses. Significantly, the spousal caretakers did not have an ongoing genetic link to their partners whereas our population is genetically linked. We postulate that this accounts for the unique presentation of complicated grief and ptsd in our population. SIGNIFICANCE OF RESULTS: We submit that this combination of complicated grief and PTSD requires a cognitive reframing of their perceived inevitability of developing breast cancer and desensitization techniques to help high risk women pursue preventative health care rather than avoiding it.

When grief heats up: pro-inflammatory cytokines predict regional brain activation.

BACKGROUND: Pro-inflammatory cytokines are associated with sickness behaviors, a set of behaviors including low mood, which are orchestrated by the brain and described as shift in motivational state. The present study investigated the hypothesis that local inflammation is associated with greater subgenual anterior cingulate cortex (sACC) activation in persons undergoing chronic stress. METHODS: Women undergoing the emotional stress of bereavement had fMRI scans during a grief elicitation task. Local inflammation was measured by salivary concentrations of two markers of pro-inflammatory cytokine activity (e.g., interleukin-1beta and soluble tumor necrosis factor receptor II). RESULTS: Analyses revealed that both inflammatory markers were positively associated with ventral prefrontal activation (e.g., sACC and orbitofrontal cortex) as well as other regions important in the emotional task such as noun retrieval (e.g., temporal cortex), and visual processing (e.g., cuneus and fusiform gyrus). In separate analyses, the ventral prefrontal activations correlated with free recall of grief-related word stimuli, but not neutral word stimuli. CONCLUSIONS: This is the first study to demonstrate the relationship between emotional processing, regional brain activation and localized inflammation in a chronically stressed population of adults.

Craving love? Enduring grief activates brain's reward center.

Complicated Grief (CG) occurs when an individual experiences prolonged, unabated grief. The neural mechanisms distinguishing CG from Noncomplicated Grief (NCG) are unclear, but hypothesized mechanisms include both pain-related activity (related to the social pain of loss) and reward-related activity (related to attachment behavior). Bereaved women (11 CG, 12 NCG) participated in an event-related functional magnetic resonance imaging scan, during grief elicitation with idiographic stimuli. Analyses revealed that whereas both CG and NCG participants showed pain-related neural activity in response to reminders of the deceased, only those with CG showed reward-related activity in the nucleus accumbens (NA). This NA cluster was positively correlated with self-reported yearning, but not with time since death, participant age, or positive/negative affect. This study supports the hypothesis that attachment activates reward pathways. For those with CG, reminders of the deceased still activate neural reward activity, which may interfere with adapting to the loss in the present.

Quality of life of couples dealing with cancer: dyadic and individual adjustment among breast and prostate cancer survivors and their spousal caregivers.

BACKGROUND AND PURPOSE: Although evidence suggests that survivors and spousal caregivers tend to experience somewhat similar levels of distress and that the survivor's distress affects his/her own quality of life, the degree to which each person's distress has an independent effect on their partner's quality of life is unknown. Thus, this study aimed to examine the dyadic effects of psychological distress on the quality of life of couples dealing with cancer. METHODS: A total of 168 married survivor-caregiver dyads participating in the American Cancer Society's Study of Cancer Survivors-I and Quality of Life Survey for Caregivers provided complete data for study variables. Participating survivors were diagnosed with either breast or prostate cancer approximately 2 years prior to participating in the study. RESULTS: Using the Actor Partner Interdependence Model, results revealed that although each person's psychological distress is the strongest predictor of their own quality of life, partner's distress and (dis)similarity in distress of the couple also play significant roles in one's quality of life. In addition, the adverse effect of having a partner who is less emotionally resourceful was especially pronounced on men's physical health. CONCLUSIONS: Our systematic investigation provided valuable evidence for identifying the subgroup of cancer survivors and their spouses who are vulnerable to poor quality of life due to their mutual psychological distress. These findings suggest that couples may benefit from interventions that enhance their ability to manage psychological distress, particularly the wife's, which may improve the mental and physical health of both partners when they are dealing with cancer.

Effects of psychological distress on quality of life of adult daughters and their mothers with cancer.

INTRODUCTION: As the population continues to age, adult daughters are more likely to be involved in caregiving. Given the fact that sharing emotional experiences is common in female relationships, (dis)similarity between mothers with cancer and their adult caregiving daughters is expected. However, the extent to which the (dis)similarity in psychological distress influences the quality of life of each person remains unknown. METHOD: This study aims at addressing this concern, using a total of 98 mother-daughter dyads participating in the American Cancer Society's Study of Cancer Survivors-I and Quality of Life Survey for Caregivers. RESULTS: Using the Actor Partner Interdependence Model, the results showed that although each person's psychological distress is the strongest predictor of their own quality of life, a mother's distress also plays a significant role in the daughter's quality of life. Specifically, when mothers experienced greater levels of psychological distress, the daughters reported better mental health but poorer physical health. CONCLUSIONS: Our findings on the disproportionately strong association between psychological distress of mothers with cancer and their adult caregiving daughters' quality of life suggest that caregiving daughters may benefit from programs designed to assist them to cope better with their mothers' psychological distress when both are living with cancer.

Family caregivers and guilt in the context of cancer care.

BACKGROUND: Guilt as a key emotional phenomenon in the cancer-caregiving experience is an understudied issue. OBJECTIVE: The purpose of this study is to identify demographic characteristics of cancer caregivers and care-related stress factors that are associated with their feelings of caregiver guilt, as well as to explore the effect of caregiver guilt on their adjustment outcomes. METHOD: A total of 739 caregivers of cancer survivors completed a survey (66.7% response rate), of which 635 provided complete data for the measures in this study. RESULTS: Hierarchical regression analyses revealed that certain caregiver demographics (i.e., younger age, adult offspring, employed) and care-related stress factors (i.e., greater impact on schedule, less perceived caregiving competence, poorer overall health of the care-recipient) were significantly related to caregiver guilt. Higher levels of psychological distress and poorer mental, social, and physical functioning were significantly associated with caregiver guilt, above and beyond the variance accounted for by the covariates. CONCLUSION: Results suggest that caregiver guilt compromises the psychosocial and somatic adjustment of cancer caregivers. Guilt may be a cardinal feature of the caregiving experience, and to fully understand the implications of this complex phenomenon, more research is needed.

Psychological distress of female cancer caregivers: effects of type of cancer and caregivers' spirituality.

INTRODUCTION: This study examined the effects of the survivor's cancer type (gender-specific vs nongender-specific) and the female caregiver's spirituality and caregiving stress on the caregiver's psychological distress. Cancer caregivers, who were nominated by cancer survivors, participated in a nationwide quality-of-life survey with 252 caregivers providing complete data for the variables. PATIENTS AND METHODS: Breast and ovarian cancer were categorized as gender-specific types of cancer (GTC+), whereas kidney, lung, non-Hodgkin's lymphoma (NHL), and skin melanoma cancers were GTC-. Spirituality, caregiving stress, and psychological distress were measured using the functional assessment of chronic illness therapy--spiritual well-being, stress overload subscale, and profile of mood states--short form, respectively. RESULTS AND DISCUSSION: Hierarchical regression analyses revealed that female caregivers whose care recipient was diagnosed with a nongender specific type of cancer (GTC- group) reported higher psychological distress than did the GTC+ group. The GTC- group also reported lower spirituality and higher caregiving stress related to higher psychological distress than did the GTC+ group. In addition, the beneficial effect of spirituality on reducing psychological distress was more pronounced among the GTC- group or when caregiving stress increased. CONCLUSIONS: Our findings suggest that female caregivers of survivors with a nongender-specific cancer may benefit from programs designed to reduce their psychological distress, and caregivers who are low in spirituality need help to derive faith and meaning in the context of cancer care.

Psychiatric evaluations of heart transplant candidates: predicting post-transplant hospitalizations, rejection episodes, and survival.

The authors assessed the validity of psychiatric evaluations for orthotopic heart transplant candidates with respect to predicting adverse post-transplant outcomes. A group of 108 transplant recipients were followed for an average of 970 days, and pre-transplant evaluations were retrospectively coded for psychiatric risk factors. Previous suicide attempts, poor adherence to medical recommendations, previous drug or alcohol rehabilitation, and depression significantly predicted attenuated survival times. Also, past suicide attempt was associated with a greater risk for post-transplant infection. Assessment and early treatment for these risk factors may reduce post-transplant morbidity and mortality.

Gender differences in caregiving stress among caregivers of cancer survivors.

Despite a growing body of research on male caregivers, limited information is available on male caregivers of cancer survivors. Furthermore, few studies have examined the unique contribution of caregiver esteem as well as care-recipient's functional status as potential mediators of the link between gender and caregiving stress. Thus, the present study examines how the caregiver's perception of providing care to a spouse with cancer differs by gender. The proposed mediators, caregiver's esteem and care-recipient's psychosocial and physical functioning, were tested simultaneously, utilizing structural equation modeling. Results revealed that both caregiver's esteem and care-recipient's psychosocial functioning were significant mediators, but in different directions. Specifically, husband caregivers reported higher caregiver's esteem, which resulted in reporting less stress from providing care to their wife with cancer. On the other hand, when husband caregivers provided care to their wife with poorer psychosocial functioning, they reported greater stress from caregiving. Husband caregivers will benefit from programs designed to educate them to effectively assist their wife's psychosocial adjustment to cancer by reducing their stress from providing care.

Psychological adjustment of cancer caregivers with multiple roles.

Guided by the role strain and the role enhancement theories, this study examined the effect of caregivers' multiple roles, such as being employed and taking care of minors in their household, on their psychological adjustment. Of the caregivers who completed the American Cancer Society's Quality of Life Survey for Caregivers, 457 caregivers who were middle-aged (18-64) and provided complete data for the study variables were included in the analyses. The indicators of the outcome variables, namely, the levels of the caregivers' psychological adjustment, were cancer caregiving stress, management of meaning out of providing care, and negative and positive affect. Multivariate general linear modeling analyses revealed that employed caregivers who were also taking care of children reported higher levels of caregiving stress and negative affect. In contrast, employed caregivers who were not taking care of children reported greater levels of managing meaning of caregiving experience. The findings provide partial support for the role strain theory, that the more social roles a caregiver carries out, the more likely the caregiver is to experience stress and negative affect. The findings also suggest that when providing care for cancer survivors, caregivers may benefit from being employed. These findings have significant implications for developing targeted programs to reduce the psychological distress of cancer caregivers with multiple roles and to assist them in recognizing their caregiving experience as meaningful.
