Quality of life and emotional distress in advanced prostate cancer survivors undergoing chemotherapy

Prostate cancer continues to occur in over 230,000 men each year. Although the majority of these will be diagnosed in the early stages, there remains a proportion who will either be diagnosed in late stage disease or develop progressive disease. In patients with advanced disease, research has recently focused on using chemotherapy for symptom management and palliation. Given that the focus is not on cure, the effect of chemotherapy on quality of life is of utmost importance. The present article will 1) summarize the current chemotherapeutic studies that have included a quality of life component, with a particular focus on pain and fatigue, 2) discuss the issue of distress in advanced prostate cancer patients treated with chemotherapy, and 3) suggest future research directions. From the studies that have investigated quality of life, it appears that several chemotherapeutic agents reduce pain and fatigue, although the development of fatigue is often the dose-limiting factor of some agents. The assessment of overall quality of life has occurred in several studies, however, an examination into the impact of chemotherapy on functional status and interpersonal relationships has not been studied. Finally, in contrast to the numerous studies in early stage prostate cancer patients, the presence and effect of distress in chemotherapy-treated prostate patients has not been examined. As such, increased attention is needed to quality of life during phase I-III chemotherapy trials

Minimal Contact Intervention with Autologous BMT Patients: Impact on QOL and Emotional Distress

Bone marrow transplantation (BMT) is often a last treatment option for individuals who have experienced relapse or treatment failure and is often accompanied by increased levels of distress and reductions in quality of life (QOL). Despite this, few studies have been designed to improve post-BMT QOL and reduce distress. The current study examined the course of distress and QOL in 26 autologus BMT patients and the effect on distress and QOL of providing a minimal contact workbook intervention. Physical well-being decreased following the BMT, but increased at 2- and 6-month follow-up assessments, and distress did not significantly vary over the course of the study for patients in the standard care and workbook intervention groups. Examination of the reasons for the lack of group differences revealed that approximately half of the individuals randomized to the workbook intervention did not look at the material; with those that did reporting higher QOL, decreased anxiety, more adaptive coping, and decreased religiosity. The results argue for the importance of targeting patients at need prior to the transplant procedure, triaging them based on specific characteristics, and providing treatments that match these characteristics.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44854/1/10880_2004_Article_464477.pd

Understanding Chest Pain: What Every Psychologist Should Know

Chest pain is one of the most frequent presenting complaints in Emergency Rooms and other medical settings. A considerable number of these patients do not have significant coronary artery disease. This led to plausible alternative explanations for these presenting symptoms and these patients tend to have unremarkable cardiac outcomes. Nevertheless, many studies have also documented that symptoms and related disability persist in the face of reassurances about benign cardiac status. Given the implied threat of chest pain (e.g., myocardial infarction) and the presence of chest pain symptoms in other noncardiac conditions (including anxiety and panic), it is not surprising that many of these patients present with considerable emotional distress. Consequently, chest pain symptoms represent diagnostic and treatment dilemmas for physicians and psychologists alike. The extent to which cardiac and noncardiac factors contribute to all forms of chest pain remains unknown. The function of this review is to provide mental health professionals with a primer on relevant clinical issues in chronic chest pain. We examine several common medical and psychiatric causes of chronic chest pain and selectively review (1) the relevant medical and psychiatric diagnostic and treatment considerations for chest pain and (2) the hypothetical biobehavioral mechanisms relevant to psychological intervention, (3) while expanding on existing conceptual models for understanding chest pain, and (4) offering some suggestions for future research.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44862/1/10880_2004_Article_418731.pd

Lipid levels and emotional distress among healthy male college students

Low lipid levels have been found in some studies to be associated with non-illness deaths (i.e. suicides, homicides and accidents). Likewise, low lipids have been associated with measures of emotional distress (e.g. anxiety, depression, hostility) in medical, psychiatric and forensic populations whose age, health status and/or personal habits make interpretation of the association problematic. The present study examined the relationship of lipid levels to emotional distress in young, healthy, male college students. To investigate possible confounding/mediating relationships, a number of clinical risk factors and demographic variables were also studied (age, drug use, alcohol use, nicotine use, exercise, obesity and resting hemodynamic values). Bivariate correlations showed that measures of emotional distress (SCL-90-R subscales, Toronto Alexithymia Scale) and clinical/demographic factors (alcohol use, age, blood pressure, weight and heart rate) were associated with lipid levels. In a hierarchical set multiple regression, only alcohol use, age, resting systolic blood pressure and the positive symptom total from the SCL-90-R were unique correlates of total cholesterol. These results add additional support to the growing evidence of an association between lipid levels and emotional functioning. Importantly, this relationship appears to exist apart from other risk factors. While various studies have focused on specific dimensions of emotional distress (i.e. anxiety, depression, hostility), the results of the present study suggest that more global measures of emotional distress might better account for the association with lipid levels.

Validation of the FACT-BRM with interferon-α treated melanoma patients

The somatic, neurocognitive, and psychiatric side effects of biological response modifiers (BRMs) have been documented in specific patient samples. Although these side effects likely have a predictable impact on patients quality of life (QOL), no instrument currently measures the cumulative effect of the various complaints patients’ report. The current study investigated the reliability and validity of the Functional Assessment of Cancer Treatment-Biological Response Modifier (FACT-BRM) scale for measuring QOL in a sample of melanoma patients receiving interferon. Measures of distress, depression, and fatigue were also obtained using standardized, well-validated instruments. Results indicate increased symptom burden, depression, and fatigue, and decreased quality of life over 4months of IFN therapy. The FACT-BRM demonstrated good psychometrics and sensitivity to change, and thus appears to be a good instrument for measuring QOL in patients receiving BRMs.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43568/1/11136_2004_Article_1694.pd

Sorting of chromosomes by magnetic separation

Chromosomes were isolated from Chinese hamster x human hybrid cell lines containing four and nine human chromosomes. Human genomic DNA was biotinylated by nick translation and used to label the human chromosomes by in situ hybridization in suspension. Streptavidin was covalently coupled to the surface of magnetic beads and these were incubated with the hybridized chromosomes. The human chromosomes were bound to the magnetic beads through the strong biotin-streptavidin complex and then rapidly separated from nonlabeled Chinese hamster chromosomes by a simple permanent magnet. The hybridization was visualized by additional binding of avidin-FITC (fluorescein) to the unoccupied biotinylated human DNA bound to the human chromosomes. After magnetic separation, up to 98% of the individual chromosomes attached to magnetic beads were classified as human chromosomes by fluorescence microscopy

Randomized clinical trial of a brief and extensive dyadic intervention for advanced cancer patients and their family caregivers

Background Few intervention programs assist patients and their family caregivers to manage advanced cancer and maintain their quality of life (QOL). This study examined (i) whether patient–caregiver dyads (i.e., pairs) randomly assigned to a brief or extensive dyadic intervention (the FOCUS Program) had better outcomes than dyads randomly assigned to usual care and (ii) whether patients' risk for distress and other factors moderated the effect of the brief or extensive program on outcomes. Methods Advanced cancer patients and their caregivers ( N  = 484 dyads) were stratified by patients' baseline risk for distress (high versus low), cancer type (lung, colorectal, breast, or prostate), and research site and then randomly assigned to a brief (three‐session) or extensive (six‐session) intervention or control. The interventions offered dyads information and support. Intermediary outcomes were appraisals (i.e., appraisal of illness/caregiving, uncertainty, and hopelessness) and resources (i.e., coping, interpersonal relationships, and self‐efficacy). The primary outcome was QOL. Data were collected prior to intervention and post‐intervention (3 and 6 months from baseline). The final sample was 302 dyads. Repeated measures MANCOVA was used to evaluate outcomes. Results Significant group by time interactions showed that there was an improvement in dyads' coping ( p  < 0.05), self‐efficacy ( p  < 0.05), and social QOL ( p  < 0.01) and in caregivers' emotional QOL ( p  < 0.05). Effects varied by intervention dose. Most effects were found at 3 months only. Risk for distress accounted for very few moderation effects. Conclusions Both brief and extensive programs had positive outcomes for patient–caregiver dyads, but few sustained effects. Patient–caregiver dyads benefit when viewed as the ‘unit of care’.

Cancer-specific worry interference in women attending a breast and ovarian cancer risk evaluation program: impact on emotional distress and health functioning

Intrusive thoughts about cancer, often identified as ‘cancer-specific worries’ or ‘cancer-specific distress’, have been postulated to be associated with dysfunction in women at increased risk of developing breast or ovarian cancer. The current study discusses the development and validation of a measure designed to assess women's perceptions of the interference such worries create in their daily functioning. Analyses revealed that approximately two-thirds of a high-risk breast cancer clinic sample perceived worries about breast cancer as interfering with their functioning across a variety of life domains. Multiple regression analyses indicated that worry interference scores predicted Profile of Mood States (POMS) Anxiety and Confusion, and Short Form-36 (SF-36) Role-Emotional and Mental Health scores after the effects of other variables such as frequency of worry about breast cancer, and having a family history of cancer had been considered. Women who perceived their worries as interfering with their functioning reported higher levels of anxiety and confusion, and diminished mental health and role functioning. The results add to the expanding area of anxiety/distress in at-risk populations by providing (1) a direct measure of the perceived interference associated with breast cancer-specific thoughts, (2) a validation of the measure via its associations with standard measures of emotional distress and health functioning, and (3) evidence of the measure's incremental predictive value in explaining distress and quality of life, after consideration of background variables, such as having a family history of cancer.

A Gene Catalogue of the Euchromatic Male-Specific Region of the Horse Y Chromosome: Comparison with Human and Other Mammals

Studies of the Y chromosome in primates, rodents and carnivores provide compelling evidence that the male specific region of Y (MSY) contains functional genes, many of which have specialized roles in spermatogenesis and male-fertility. Little similarity, however, has been found between the gene content and sequence of MSY in different species. This hinders the discovery of species-specific male fertility genes and limits our understanding about MSY evolution in mammals. Here, a detailed MSY gene catalogue was developed for the horse – an odd-toed ungulate. Using direct cDNA selection from horse testis, and sequence analysis of Y-specific BAC clones, 37 horse MSY genes/transcripts were identified. The genes were mapped to the MSY BAC contig map, characterized for copy number, analyzed for transcriptional profiles by RT-PCR, examined for the presence of ORFs, and compared to other mammalian orthologs. We demonstrate that the horse MSY harbors 20 X-degenerate genes with known orthologs in other eutherian species. The remaining 17 genes are acquired or novel and have so far been identified only in the horse or donkey Y chromosomes. Notably, 3 transcripts were found in the heterochromatic part of the Y. We show that despite substantial differences between the sequence, gene content and organization of horse and other mammalian Y chromosomes, the functions of MSY genes are predominantly related to testis and spermatogenesis. Altogether, 10 multicopy genes with testis-specific expression were identified in the horse MSY, and considered likely candidate genes for stallion fertility. The findings establish an important foundation for the study of Y-linked genetic factors governing fertility in stallions, and improve our knowledge about the evolutionary processes that have shaped Y chromosomes in different mammalian lineages
