Measuring Depression In Prostate Cancer Patients: Does The Scale Used Make A Difference?, Christopher Sharpley, Vicki Bitsika, David Christie, Myra Hunter Nov 2015

Measuring Depression In Prostate Cancer Patients: Does The Scale Used Make A Difference?, Christopher Sharpley, Vicki Bitsika, David Christie, Myra Hunter

Vicki Bitsika

This study investigated differences in the scores, relative severity and major depressive disorder (MDD) and subsyndromal depression status from three standardised self-report scales for depression in prostate cancer (PCa) patients. The Hospital Anxiety and Depression Scale Depression subscale (HADS-D), the Self-rating Depression Scale (SDS) and the Patient Health Questionnaire (PHQ-9) for depression were administered to a sample of 138 PCa patients via mail-out self-reports in Queensland, Australia during May 2014. Despite significant correlations between the total scores from the three scales, severity classification differed across the three scales and there was evidence of considerable underestimation of depression by the HADS-D …

Several dual-specificity phosphatases (DUSPs) that play key roles in the direct or indirect inactivation of different MAP kinases (MAPKs) have been implicated in human cancers over the past decade. This has led to a growing interest in identifying DUSPs and their specific inhibitors for further testing and validation as therapeutic targets in human cancers. However, the lack of understanding of the complex regulatory mechanisms and cross-talks between MAPK signaling pathways, combined with the fact that DUSPs can act as a double-edged sword in cancer progression, calls for a more careful and thorough investigation. Among the various types of brain cancer, …

Benefits And Barriers Of Cancer Practitioners Discussing Physical Activity With Their Cancer Patients, Justin Keogh, Alicia Olsen, Mike Climstein, Sally Sargeant, Lynette Jones

Sally Sargeant

Our aim was to synthesise the existing empirical literature and theoretical perspectives on the physical activity (PA) promotion practices and determinants of cancer clinicians and health professionals. We conducted a narrative review of theory and evidence to develop practice recommendations for improving the promotion of PA to cancer patients. Surveyed health professionals were aware of many benefits of PA for their cancer patients, although only ~40 % promoted PA to selected cancer patients. Walking was the most commonly promoted form of PA, with this promoted to assist patients control their weight and cardiovascular health risk. Barriers to promotion of PA …


Predictors Of Depression In Prostate Cancer Patients: A Comparison Of Psychological Resilience Versus Pre-Existing Anxiety And Depression, Christopher Sharpley, Vicki Bitsika, Addie Wootten, David Christie Jul 2015

Predictors Of Depression In Prostate Cancer Patients: A Comparison Of Psychological Resilience Versus Pre-Existing Anxiety And Depression, Christopher Sharpley, Vicki Bitsika, Addie Wootten, David Christie

Vicki Bitsika

Background: Previous anxiety and depression can influence current anxiety and depression, and psychological resilience may be a buffer against current anxiety and depression. However, despite the relevance of these two sets of predictors of anxiety and depression, and their potential in treatment planning, no reports have been published on their role in post-diagnosis anxiety and depression among prostate cancer (PCa) patients. Therefore, this study aimed to determine the roles of these predictors in a sample of men with prostate cancer. Method: Retrospective self-reports of anxiety and depression for how they were before receiving their diagnosis of PCa and at the …

Lydia Johnson

This work reports a new method to improve our recent demonstration of zinc oxide (ZnO) nanoparticles (NPs) selectively killing certain human cancer cells, achieved by incorporating Fe ions into the NPs. Thoroughly characterized cationic ZnO NPs (∼6 nm) doped with Fe ions (Zn(1-x )Fe (x) O, x = 0-0.15) were used in this work, applied at a concentration of 24 μg/ml. Cytotoxicity studies using flow cytometry on Jurkat leukemic cancer cells show cell viability drops from about 43% for undoped ZnO NPs to 15% for ZnO NPs doped with 7.5% Fe. However, the trend reverses and cell viability increases with …

joseph Ciarrochi

Background This preliminary study examined the effectiveness of an Acceptance and Commitment Therapy (ACT) intervention at improving the quality of life among cancer patients. It was hypothesised that over the course of the intervention, patients would report increased psychological flexibility through acceptance of unpleasant thoughts and feelings, and that increased psychological flexibility would lead to improvements in distress, mood, and quality of life. Method Forty-five cancer patients participated in an ACT intervention. Outcome measures included self-reported distress, mood disturbance, psychological flexibility, and quality of life. Data were collected at pre, mid, and post-intervention and at 3-month follow-up. Results The data …


Psychosocial Aspects Of Anal Cancer Screening: A Review And Recommendations, Jodie Landstra, Joseph Ciarrochi, Frank P. Deane Jul 2015

Psychosocial Aspects Of Anal Cancer Screening: A Review And Recommendations, Jodie Landstra, Joseph Ciarrochi, Frank P. Deane

joseph Ciarrochi

Cancer screening programs have the potential to decrease psychosocial wellbeing. This review investigates the evidence that anal cancer screening has an impact on psychosocial functioning and outlines considerations for supporting participants. The review suggested that screening has no significant effect on general mental health but may increase cancer-specific worry. Having worse anal or HIV symptoms, being younger, higher baseline distress or worse histology results were predictive of greater worry. The findings suggest the need to increase education campaigns, particularly targeting those with HIV infection and men who have sex with men. There is a need to develop a consensus on …

joseph Ciarrochi

Background Anal cancer rates are increasing in HIV-infected men. Screening programmes similar to prostate and cervical cancer have been recommended to reduce morbidity and mortality. Research shows that screening processes have psychological consequences that need to be considered. Limited investigation of the psychological impact of anal cancer screening has been conducted. Methods A prospective longitudinal survey of 291 men was conducted at three time points over 14 weeks at a public HIV clinic in Sydney, Australia. Self-report questionnaires measuring worry, distress, depression, anxiety, stress and health-related quality of life (SF-12) were collected. Results Those who had a biopsy recommended were …


Psychological Consequences Of Cancer Screening In Hiv, Jodie Landstra, Frank Deane, Joseph Ciarrochi Jul 2015

Psychological Consequences Of Cancer Screening In Hiv, Jodie Landstra, Frank Deane, Joseph Ciarrochi

joseph Ciarrochi

Purpose of review: There is a growing awareness of the increase in non-AIDS-defining cancers (NADC) in the HIV-infected population. Cancer screening is one means of reducing morbidity and mortality, but such screening may have psychological consequences across those with high and low-risk results, such as increased anxiety, worry and potential behavior change like increased self-examination or medical follow-up. This review examines the literature on psychological consequences of screening for NADC in HIV-infected populations. Recent findings: Anal cancer is the only cancer type in which the psychological consequence of screening has been investigated in HIV-infected populations. Screening increases worry about anal …

Survival time in patients with androgen-resistant prostate cancer. However, it provides only a modest increase in survival and is associated with significant toxicity. Therefore, there is an urgent need to identify potential adjunct therapies. Given the key role of autophagy in both tumour survival and chemoresistance, the impact of autophagy modulation on docetaxel toxicity was tested in vitro. PC-3 and LNCaP cells were pre-treated with the autophagy inhibitor 3- methyladenine (5 mM) and then exposed to various concentrations (0–100 μM) of docetaxel. Cytoxic effects of docetaxel were measured using resazurin reduction to resorufin, whilst autophagy and apoptosis was measured using …

Enhanced Urothelial Atp Release And Contraction Following Intravesical Treatment With The Cytotoxic Drug, Doxorubicin, Stanley Kang, Catherine Mcdermott, Stef Farr, R. Chess-Williams

Catherine M. McDermott

Intravesical administration of the cytotoxic drug doxorubicin is a common treatment for superficial carcinoma of the bladder, but it is associated with significant urological adverse effects. The aim of this study was to identify doxorubicin-induced changes in the local mechanisms involved in regulating bladder function. As a model of intravesical doxorubicin administration in patients, doxorubicin (1 mg/mL) was applied to the luminal surface of porcine bladders for 60 min. Following treatment, the release of urothelial/lamina propria mediators (acetylcholine (Ach), ATP and prostaglandin E2 (PGE2) and contractile responses of isolated tissue strips was investigated. Doxorubicin pretreatment did not affect contractile responses …
