Using a positive self-talk intervention to enhance coping skills in breast cancer survivors: lessons from a community-based group delivery model

PURPOSE

Cancer survivorship is a distinct phase of the cancer continuum, and it can have myriad associated stresses and challenges. The purpose of the present study was to evaluate the effectiveness of a positive self-talk (pst) intervention in enhancing the coping skills and improving the psychological well-being of breast cancer survivors.

METHODS

Participants (n = 38) were recruited from 5 support groups in a small eastern Canadian province. Support groups were randomly assigned to either a control (n = 18) or an intervention (n = 20) condition. Intervention participants were pre-tested, received a 2-hour pst in-person group workshop and a 10-minute "booster" session by telephone, and completed post-test questionnaires 1 month later.

RESULTS

Intervention participants reviewed the workshop favourably. Nearly all participants used the intervention in everyday life, were able to accurately describe how pst works, and found that pst had a considerable impact on their ability to cope with cancer and related sequelae. However, the descriptive findings from the workshop evaluation did not translate into significant differences between the intervention and control groups on the psychometric measures.

CONCLUSIONS

The pst intervention, delivered in a community group model, was positively received and effective in teaching participants about pst and how pst can be used to enhance coping skills for breast cancer patients. However, the intervention did not promote significantly greater levels of change in anxiety, depression, mood disturbance, or coping ability for intervention participants. The unique challenges of community-level psychological intervention are explored.

Strengthening clinical cancer research in the United Kingdom

BACKGROUND

In 1999, 270,000 cases of cancer were registered in the United Kingdom, placing a large burden on the NHS. Cancer outcome data in 1999 suggested that UK survival rates were poorer than most other European countries. In the same year, a Department of Health review noted that clinical trials accrual was poor (<3.5% of incident cases) and hypothesised that increasing research activity might improve outcomes and reduce the variability of outcomes across England. Thus, the National Cancer Research Network (NCRN) was established to increase participation in cancer clinical research.

METHODS

The NCRN was established in 2001 to provide a robust infrastructure for cancer clinical research and improvements in patient care. Remit of NCRN is to coordinate, support and deliver cancer clinical research through the provision of research support staff across England. The NCRN works closely with similar networks in Scotland, Wales and the Northern Ireland. A key aim of NCRN is to improve the speed of research and this was also assessed by comparing the speed of study delivery of a subset of cancer studies opening before and after NCRN was established.

RESULTS

Patient recruitment increased through NCRN, with almost 32,000 (12% of annual incident cases) cancer patients being recruited each year. Study delivery has improved, with more studies meeting the recruitment target - 74% compared with 39% before NCRN was established.

CONCLUSION

The coordinated approach to cancer clinical research has demonstrated increased accrual, wide participation and successful trial delivery, which should lead to improved outcomes and care.

Germline single-nucleotide polymorphisms (SNPs) associated with response of urothelial carcinoma (UC) to platinum-based therapy: The role of the host

236

Background: Platinum-based therapy improves outcome in neoadjuvant and metastatic UC. Since cell-line and human subject studies in other cancers show germline associations with platinum response, we hypothesized that germline variation also identifies genes that determine UC response to platinum-based therapy.

Methods: Saliva or blood was prospectively collected from 651 UC patients (pts) diagnosed between 1984 and 2010. SNPs (n=80) were selected based on previously reported associations with UC and/or platinum response and genotyped using Sequenom MassArray iPLEX system. Samples and SNPs were filtered for genotyping rate (<0.8), minor allele frequency (<0.05) and departures from Hardy-Weinberg equilibrium (<1E-03). Clinical data were ascertained and linked with the genomic data in an anonymized manner. This analysis focused on 199 pts who received cisplatin or carboplatin and were eligible for response assessment (RES=partial response or complete response, n=90). Associations between SNPs and RES were tested using one and two degree of freedom tests.

Results: Sixty-nine pts received neoadjuvant therapy (RES=54%), 126 chemo-naive pts received first-line metastatic treatment (RES=37%) and 4 received systemic treatment after prior chemoradiotherapy (RES=25%). We expected 4 associations due to chance alone at p < 0.05. However, on univariate analysis using a 2 degree of freedom test, 9 SNPs were associated (p < 0.05) with RES. Individual odds ratios (ORs) ranged from 0.32 to 3.29 with p-values ranging from 0.006 to 0.05. In analysis of rs9344 (CCND1) in all treated pts, 75/148 (51%) responded with AG/GG compared to 12/44 (27%) with AA [p=0.005312, OR 2.74 (CI 1.34, 5.92)]. In neoadjuvant pts treated with cisplatin, rs9344 analysis showed 29/48 (60%) responses in AG/GG pts compared to 5/17 (29%) with AA [p=0.026, OR 3.66 (CI 1.16, 13.1)].

Conclusions: We identified associations between 9 SNPs and response of UC to platinum-based therapy that are biologically and clinically relevant. A larger study will be required to independently validate these findings. Additional investigation of associations with time to metastasis and overall survival is ongoing.

Müller glial dysfunction during diabetic retinopathy in rats is linked to accumulation of advanced glycation end-products and advanced lipoxidation end-products

AIMS/HYPOTHESIS

The impact of AGEs and advanced lipoxidation end-products (ALEs) on neuronal and Müller glial dysfunction in the diabetic retina is not well understood. We therefore sought to identify dysfunction of the retinal Müller glia during diabetes and to determine whether inhibition of AGEs/ALEs can prevent it.

METHODS

Sprague-Dawley rats were divided into three groups: (1) non-diabetic; (2) untreated streptozotocin-induced diabetic; and (3) diabetic treated with the AGE/ALE inhibitor pyridoxamine for the duration of diabetes. Rats were killed and their retinas were evaluated for neuroglial pathology.

RESULTS

AGEs and ALEs accumulated at higher levels in diabetic retinas than in controls (p < 0.001). AGE/ALE immunoreactivity was significantly diminished by pyridoxamine treatment of diabetic rats. Diabetes was also associated with the up-regulation of the oxidative stress marker haemoxygenase-1 and the induction of glial fibrillary acidic protein production in Müller glia (p < 0.001). Pyridoxamine treatment of diabetic rats had a significant beneficial effect on both variables (p < 0.001). Diabetes also significantly altered the normal localisation of the potassium inwardly rectifying channel Kir4.1 and the water channel aquaporin 4 to the Müller glia end-feet interacting with retinal capillaries. These abnormalities were prevented by pyridoxamine treatment.

CONCLUSIONS/INTERPRETATION

While it is established that AGE/ALE formation in the retina during diabetes is linked to microvascular dysfunction, this study suggests that these pathogenic adducts also play a role in Müller glial dysfunction.

Factors influencing uptake of HIV care and treatment among children in South Africa - a qualitative study of caregivers and clinic staff

Despite antiretroviral therapy rollout in South Africa, fewer children than expected are accessing HIV care services. Our objectives were to describe barriers and facilitators of uptake of HIV care among children. Our study involved six private-sector clinics which provide HIV care free-of-charge in and around Gauteng province, South Africa. In-depth interviews were conducted in July 2008 with 21 caregivers of HIV-infected children attending these clinics, 21 clinic staff members and three lead members of staff from affiliated care centres. Many children were only tested for HIV after being recurrently unwell. The main facility-related barriers reported were long queues, negative staff attitudes, missed testing opportunities at healthcare facilities and provider difficulties with paediatric counselling and venesection. Caregivers reported lack of money for transport, food and treatments for opportunistic infections, poor access to welfare grants and lack of coordination amongst multiple caregivers. Misperceptions about HIV, maternal guilt and fear of negative repercussions from disclosure were common. Reported facilitators included measures implemented by clinics to help with transport, support from family and day-care centres/orphanages, and seeing children's health improve on treatment. Participants felt that better public knowledge about HIV would facilitate uptake. Poverty and the implications of children's HIV infection for their families underlie many of these factors. Some staff-related and practical issues may be addressed by improved training and simple measures employed at clinics. However, changing caregiver attitudes may require interventions at both individual and societal levels. Healthcare providers should actively promote HIV testing and care-seeking for children.

European guidelines on managing adverse effects of medication for ADHD

The safety of ADHD medications is not fully known. Concerns have arisen about both a lack of contemporary-standard information about medications first licensed several decades ago, and signals of possible harm arising from more recently developed medications. These relate to both relatively minor adverse effects and extremely serious issues such as sudden cardiac death and suicidality. A guidelines group of the European Network for Hyperkinetic Disorders (EUNETHYDIS) has therefore reviewed the literature, recruited renowned clinical subspecialists and consulted as a group to examine these concerns. Some of the effects examined appeared to be minimal in impact or difficult to distinguish from risk to untreated populations. However, several areas require further study to allow a more precise understanding of these risks.

Mental health nurses' and allied health professionals' perceptions of the role of the Occupational Health Service in the management of work-related stress: how do they self-care?

Higher rates of stress-related sickness are found in health care professionals when compared with other sectors. The annual direct cost of absence to the National Health Service is £1.7 billion. Increased clinical demand, long hours, low staffing and a lack of support from colleagues and management are contributing to absenteeism, somatic complaints and mental health problems. Mental health work is inherently stressful and levels of work stress experienced by mental health nurses are especially high. The study investigated mental health nurses' and allied health professionals' (AHPs) awareness and knowledge of the service provided by the Occupational Health Service (OHS) and identified work-related stress and self-care strategies within these two groups. Nurses and AHP staff employed in mental health services in a Scottish healthboard area were invited to complete an anonymous questionnaire. Results demonstrated that staff found their contact with the OHS to be a positive experience. They considered direct patient care to be less stressful than the organizational constraints they work under, and they reported a lack of support from both their peer groups and management. There should be recognition of the increased stress that hospital-based nurses and AHPs experience. These areas should be scrutinized and reviewed further to support staff within these environments in accordance with organizational objectives.

Ophthalmic, clinical and visual electrophysiological findings in children born to mothers prescribed substitute methadone in pregnancy

BACKGROUND AND AIMS

There are growing concerns regarding visual outcome of infants exposed to opiates (including substitute methadone) and/or benzodiazepines in utero. We describe the combined ophthalmology and visual electrophysiology findings in 20 infants and children who had been exposed to substitute methadone and other drugs of misuse in utero.

METHODS

This was a descriptive case series of 20 patients, all of whom had been referred to a paediatric visual electrophysiology service because of concerns regarding visual function, and all of whom had been exposed to methadone in utero. All children underwent a full ophthalmic and orthoptic examination as well as visual electrophysiology testing deemed appropriate on an individual basis. A review was undertaken of paediatric case notes and of maternal antenatal urine toxicology.

RESULTS

Ophthalmic abnormalities included reduced acuity (95%), nystagmus (70%), delayed visual maturation (50%), strabismus (30%), refractive errors (30%), and cerebral visual impairment (25%). Visual electrophysiology was abnormal in 60%. A quarter of the children had associated neurodevelopmental abnormalities. The majority of children with nystagmus (79%) had been treated for neonatal abstinence syndrome (NAS).

CONCLUSION

Infants born to drug-misusing mothers prescribed methadone in pregnancy are at risk of a range of visual problems, the underlying causes of which are not clear. Those infants with NAS severe enough to receive pharmaceutical treatment may be at particular risk of developing nystagmus. The inclusion of visual electrophysiology in comprehensive visual assessment of children exposed to substance misuse in utero may help clarify the underlying causes by differentiating abnormalities of retinal and cortical origin.

Visual electrophysiological findings in CHARGE syndrome with bilateral colobomas: a case report

Colobomas are the major ophthalmic manifestation of CHARGE syndrome. Ophthalmological advice may be sought for an infant diagnosed with CHARGE syndrome presenting with coloboma, and electrophysiology can be particularly useful in assessing retinal and cortical function at an early age. Here we describe electrophysiology findings in a four-week-old infant born with bilateral coloboma, more extensive in the right eye, as part of CHARGE syndrome. The left eye showed robust ERGs indicating near-normal rod and cone function. The right eye ERG amplitudes were relatively reduced being around one half to two-thirds that of the left eye ERGs. Flash VEPs were present from both left and right eyes, but the right eye VEP was smaller and delayed relative to that of the left eye. By 5 years of age, right eye acuity was approximately 6/1000 and left eye acuity was 6/12 (Cardiff cards). In cases such as this, it is helpful to give parents a reasonable prediction of visual outcome as soon as possible, allowing instigation of appropriate management and permitting parents to begin to come to terms with the diagnosis. Electrophysiology can provide valuable information on visual function when behavioural testing is limited by the child's ability to co-operate, such as during the early weeks of life.

The economic impact on families when a child is diagnosed with cancer

OBJECTIVE

In a study conducted in New Brunswick and Newfoundland and Labrador, we examined the economic impact on families caring for a child with cancer.

METHODS

We undertook semi-structured interviews with 28 French and English families with a child diagnosed with cancer in the last 10 years.

RESULTS

Families who care for a child with cancer incur considerable costs during the diagnostic, treatment, and follow-up care phases of the disease. Four major themes emerged from this qualitative study as contributing factors for these expenses: necessary travel; loss of income because of a reduction or termination of parental employment; out-of-pocket treatment expenses; and inability to draw on assistance programs to supplement or replace lost income. In addition, many of the decisions with regard to the primary caregiver were gendered. Typically, the mother is the one who terminated or reduced work hours, which affected the entire family's financial well-being.

CONCLUSIONS

For families with children diagnosed with cancer, financial issues emerged as a significant concern at a time when these families were already consumed with other challenges. This economic burden can have long-term effects on the financial security, quality of life, and future well-being of the entire family, including the siblings of the affected child, but in particular the mother. Financial assistance programs for families of seriously ill children need to be revisited and expanded.
