Does stress increase risk of breast cancer? A 15-year prospective study.

OBJECTIVE: The possible impact of stress on cancer incidence remains controversial. We prospectively evaluated associations between life event stressors, social support, personality characteristics (optimism, anger control, antiemotionality), and risk of developing primary breast cancer (BCa), in women at increased familial risk of BCa. METHODS: A prospective cohort, repeated measures design was used. Recruitment was through the Kathleen Cuningham Foundation Consortium for Research into Familial Breast Cancer, which collects genetic, epidemiological, and clinical data from Australasian families with multiple BCa cases. Acute and chronic stressors for the prior 3 years and psychosocial, clinical, and epidemiological variables were measured at cohort entry and at 3-yearly intervals. Cox proportional hazard regression analysis controlling for BCa risk factors and familial clustering was undertaken. The primary outcome was histopathologically confirmed BCa (invasive or ductal carcinoma in situ, including occult cases diagnosed during risk-reducing mastectomy). RESULTS: Of 3595 consecutive women invited to participate, 3054 (85.0%) consented. Of these, 2739 (89.7%) from 990 families (range 1-16 per family) completed at least 1 assessment point. During the study, 103 women were diagnosed with BCa. No stressor or psychosocial variable or interaction between them was significantly associated with BCa in unadjusted or adjusted models (total acute stressors HR = 1.03 [0.99-1.08], P = .19; total chronic stressors HR = 1.0 [0.90-1.11], P = .98). CONCLUSIONS: This study did not demonstrate an association between acute and chronic stressors, social support, optimism, antiemotionality or anger control, and BCa risk. Women should focus on proven methods of BCa risk reduction.

KContact, an enhanced intervention for contact between children in out-of-home care and their parents: protocol for a cluster randomised controlled trial.

BACKGROUND: When children are unable to safely live at home with their parents, contact between these children and their parents is considered, in most cases, important for maintaining children's sense of identity and relationships with their parents. However, the research evidence on contact is weak and provides little guidance on how to manage contact and when it is beneficial or potentially harmful. The evidence in relation to contact interventions with parents and their children who are to remain in long-term care is the most limited. A small number of studies have been identified where interventions which were therapeutic, child-focused and with clear goals, particularly aimed at preparing and supporting parents, showed some promising results. This trial aims to build on the existing evidence by trialling an enhanced model of contact in multiple sites in Australia. METHODS/DESIGN: This study is a cluster randomised controlled trial of an enhanced contact intervention with children in long-term care who are having supervised contact with their parents. Intervention sites will implement the kContact intervention that increases the preparation and support provided to parents in relation to contact. Baseline and follow-up interviews are being conducted with parents, carers and agency workers at intervention and control sites. Follow-ups interviews will assess whether there has been an increase in children's emotional safety and a reduction in distress in response to contact visits with their parents (the primary outcome variable as measured using the Strength and Difficulties Questionnaire), improved relationships between children and their parents, improved parental ability to support contact, and fewer contact visits cancelled. DISCUSSION: By increasing the evidence base in this area, the study aims to better guide the management and supervision of contact visits in the out-of-home care context and improve outcomes for the children and their families. TRIAL REGISTRATION: Trial registered on 7 April 2015 with the Australian New Zealand Clinical Trials Registry ACTRN12615000313538.

Long-term outcomes of risk-reducing surgery in unaffected women at increased familial risk of breast and/or ovarian cancer.

This study prospectively investigated long-term psychosocial outcomes for women who opted for risk-reducing mastectomy (RRM) and/or risk-reducing salpingo-oophorectomy (RRSO). Unaffected women from high-risk breast cancer families who had completed baseline questionnaires for an existing study and subsequently underwent RRM and/or RRSO, completed measures of perceived breast and ovarian cancer risk, anxiety, depression, cancer-related anxiety, body image, sexual functioning, menopausal symptoms, use of hormone replacement therapy and decision regret 3 years post-surgery. Outcomes were compared to age- and risk-matched controls. Participants (N = 233) were 17 women who had RRM (39 controls), 38 women who had RRSO (94 controls) and 15 women who had RRM + RRSO (30 controls). Women who underwent RRM and those who underwent RRM + RRSO reported reductions in perceived breast cancer risk and perceived breast and ovarian cancer risk respectively, compared to their respective controls. RRM women reported greater reductions in cancer-related anxiety compared with both controls and RRSO women. RRSO women reported more sexual discomfort than controls and more urogenital menopausal symptoms than controls and RRM only women. No differences in general anxiety, depression or body image were observed. Regret was associated with greater reductions in body image since surgery and more sexual discomfort, although overall regret levels were low. Women who undergo RRM experience psychological benefits associated with reduced breast cancer risk. Although women who undergo RRSO experience some deterioration in sexual and menopausal symptoms, they do not regret their surgery decision. It is vital that women considering these procedures receive detailed information about potential psychosocial consequences.

Supporting Family Caregivers With Palliative Symptom Management: A Qualitative Analysis of the Provision of an Emergency Medication Kit in the Home Setting.

PURPOSE: The purpose of this qualitative analysis was to examine the experiences of family caregivers supporting a dying person in the home setting. In particular, it explores caregivers' perceptions of receiving palliative care at home when supplied with an emergency medication kit (EMK). RESULTS: Most family caregivers described preexisting medication management strategies that were unable to provide timely intervention in symptoms. The EMK was largely viewed as an effective strategy in providing timely symptom control and preventing readmission to inpatient care. Caregivers reported varying levels of confidence in the administration of medication. CONCLUSION: The provision of an EMK is an effective strategy for improving symptom control and preventing inpatient admissions of home-dwelling palliative care patients.

The Use of Emergency Medication Kits in Community Palliative Care: An Exploratory Survey of Views of Current Practice in Australian Home-Based Palliative Care Services.

Improving symptom management for palliative care patients has obvious benefits for patients and advantages for the clinicians, as workload demands and work-related stress can be reduced when the emergent symptoms of patients are managed in a timely manner. The use of emergency medication kits (EMKs) can provide such timely symptom relief. The purpose of this study was to conduct a survey of a local service to examine views on medication management before and after the implementation of an EMK and to conduct a nationwide prevalence survey examining the use of EMKs in Australia. Most respondents from community palliative care services indicated that EMKs were not being supplied to palliative care patients but believed such an intervention could improve patient care.

Delirium in advanced cancer: screening for the incidence on admission to an inpatient hospice unit.

BACKGROUND: Delirium is a common underdiagnosed condition in advanced cancer leading to increased distress, morbidity, and mortality. Screening improves detection but there is no consensus as to the best screening tool to use with patients with advanced cancer. OBJECTIVE: To determine the incidence of delirium in patients with advanced cancer within 72 hours of admission to an acute inpatient hospice using clinical judgement and validated screening tools. METHOD: One hundred consecutive patients with advanced cancer were invited to be screened for delirium within 72 hours of admission to an acute inpatient hospice unit. Two validated tools were used, the Delirium Rating Scale-Revised 98 (DRS-R-98) and the Confusion Assessment METHOD (CAM) shortened diagnostic algorithm. These results were compared with clinical assessment by review of medical charts. RESULTS: Of 100 consecutive admissions 51 participated and of these 22 (43.1%) screened positive for delirium with CAM and/or DRS-R-98 compared to 15 (29.4%) by clinical assessment. Eleven (21.6%) were identified as hypoactive delirium and 5 (9.8%) as subsyndromal delirium. CONCLUSION: This study confirms that delirium is a common condition in patients with advanced cancer. While there remains a lack of consensus regarding the choice of delirium screening tool this study supports the CAM as being appropriate. Further research may determine the optimal screening tool for delirium enabling the development of best practice clinical guidelines for routine medical practice.

Establishing research in a palliative care clinical setting: perceived barriers and implemented strategies.

There are many challenges in developing research projects in research-naïve clinical settings, especially palliative care where resistance to participate in research has been identified. These challenges to the implementation of research are common in nursing practice and are associated with attitudes towards research participation, and some lack of understanding of research as a process to improve clinical practice. This is despite the professional nursing requirement to conduct research into issues that influence palliative care practice. The purpose of this paper is to describe the process of implementing a clinical research project in collaboration with the clinicians of a palliative care community team and to reflect on the strategies implemented to overcome the challenges involved. The challenges presented here demonstrate the importance of proactively implementing engagement strategies from the inception of a research project in a clinical setting.

Body image as a predictor of psychopathology in surgical patients with colorectal disease.

OBJECTIVE: This study aimed to test the relevance of a cognitive behavioural model of body image in a prospective study of colorectal surgery patients and to determine if pre-existing body image disturbance influenced psychological adjustment following surgery. METHODS: Sixty-seven adult consecutive colorectal surgery patients completed measures assessing psychopathology, body image related beliefs and health related quality of life during pre-admission for surgery using a questionnaire battery. Each participant was followed up three months after surgery. RESULTS: Depression and anxiety were positively correlated with body image disturbance and self evaluation at baseline. Those patients who went on to receive stomas experienced a significant deterioration in their body image that was not observed in those whose surgery did not result in the formation of a stoma. In the regression analysis, body image disturbance was a significant predictor of baseline levels of depression and emotional quality of life. Initial levels of body image disturbance remained a significant predictor of depression and anxiety at follow up assessment after medical variables and baseline levels of depression and anxiety, respectively, had been controlled for. CONCLUSION: Our findings support the hypothesis that pre-existing vulnerabilities in body image influence emotional adjustment during the recovery phase following surgery. Further research on screening for body image disturbance in surgical patients in order to promote adjustment is warranted.

Predictors of breast cancer screening behavior in women with a strong family history of the disease.

This study applied the self-regulation model to examine cognitive and emotional predictors of screening in unaffected women with a strong family history of breast cancer. 748 unaffected female members of an Australian registry of multiple-case breast cancer families formed the sample. Participants completed a baseline psychosocial questionnaire and a screening questionnaire 3 years later. Multinomial logistic regression was employed to determine predictors of under- and over-screening according to national guidelines. At follow-up 16% of women under-screened and 10% over-screened with mammography; 55% under-screened with clinical breast examination (CBE); and 9% over-screened with breast self-examination (BSE). Of the women found screening according to guidelines for mammography 72% reported ever having received specific recommendations for mammography screening from a health professional. Compared to appropriate screeners, under-screeners on mammography were less likely to have received a screening recommendation (as were under-screeners on CBE), were younger and reported lower perceived breast cancer risk, but were at higher relative risk (RR) of breast cancer and were more likely to report elevated depression. Over-screeners on mammography were more likely to be younger and have a lower RR of breast cancer. Over-screeners on BSE reported elevated cancer-specific anxiety, were less likely to be university educated and more likely to have received a recommendation for BSE. Under- and over-screening is common in women with a strong family history of breast cancer. Evaluation of interventions targeting perceived risk of breast cancer, anxiety and depression are needed to ensure women obtain accurate advice from relevant specialists and enact screening recommendations.
