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

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

Population Bottlenecks as a Potential Major Shaping Force of Human Genome Architecture

The modern synthetic view of human evolution proposes that the fixation of novel mutations is driven by the balance among selective advantage, selective disadvantage, and genetic drift. When considering the global architecture of the human genome, the same model can be applied to understanding the rapid acquisition and proliferation of exogenous DNA. To explore the evolutionary forces that might have morphed human genome architecture, we investigated the origin, composition, and functional potential of numts (nuclear mitochondrial pseudogenes), partial copies of the mitochondrial genome found abundantly in chromosomal DNA. Our data indicate that these elements are unlikely to be advantageous, since they possess no gross positional, transcriptional, or translational features that might indicate beneficial functionality subsequent to integration. Using sequence analysis and fossil dating, we also show a probable burst of integration of numts in the primate lineage that centers on the prosimian–anthropoid split, mimics closely the temporal distribution of Alu and processed pseudogene acquisition, and coincides with the major climatic change at the Paleocene–Eocene boundary. We therefore propose a model according to which the gross architecture and repeat distribution of the human genome can be largely accounted for by a population bottleneck early in the anthropoid lineage and subsequent effectively neutral fixation of repetitive DNA, rather than positive selection or unusual insertion pressures

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’.

Outcomes in children with hemophilia A with inhibitors: Results from a noninterventional study

Background: Data regarding management of pediatric persons with hemophilia A (PwHA) with factor VIII (FVIII) inhibitors are limited. This prospective noninterventional study (NCT02476942) evaluated annualized bleeding rates (ABRs), safety, and health-related quality of life (HRQoL) in pediatric PwHA with FVIII inhibitors. Procedure: PwHA aged &lt;12 years with current FVIII inhibitors and high-titer inhibitor history were enrolled. Participants remained on usual treatment; no interventions were applied. Outcomes included ABR, safety, and HRQoL. Results: Twenty-four PwHA aged 2-11 years (median 7.5) were enrolled and monitored for 8.7-44.1 weeks (median 23.4). In the episodic (n = 10) and prophylactic (n = 14) groups, respectively, 121 of 185 (65.4%) and 101 of 186 (54.3%) bleeds were treated using activated prothrombin complex concentrate (aPCC) and/or recombinant activated FVII (rFVIIa). ABRs (95% confidence interval) were 19.4 (13.2-28.4) and 18.5 (14.2-24.0) for treated bleeds, and 32.7 (20.5-52.2) and 33.1 (22.4-48.9) for all bleeds, respectively. Most prophylactic group participants (92.9%) were prescribed aPCC; 50% adhered to their prescribed treatment regimen. Adherence to prophylactic rFVIIa was not assessed. Serious adverse events included hemarthrosis (12.5%) and mouth hemorrhage (12.5%); the most common nonserious adverse event was viral upper respiratory tract infection (12.5%). HRQoL showed functional impairment at baseline; scores remained stable throughout, with little intergroup variation. Conclusions: ABRs remained high in pediatric PwHA with inhibitors receiving standard treatment. This study demonstrates the need for more effective treatments, with reduced treatment burden, to prevent bleeds, increase prophylaxis adherence, and improve patient outcomes.Was funded by F.
