Use of DNA image cytometry in conducting oral cancer screening in rural India.

OBJECTIVES: Oral cancer screening can assist in the early detection of oral potentially malignant lesions (OPMLs) and prevention of oral cancers. It can be challenging for clinicians to differentiate OPMLs from benign conditions. Adjunct screening tools such as fluorescence visualisation (FV) and DNA image cytometry (DNA-ICM) have shown success in identifying OPMLs in high-risk clinics. For the first time we aimed to assess these technologies in Indian rural settings and evaluate if these tools helped clinicians identify high-risk lesions during screening. METHODS: Dental students and residents screened participants in five screening camps held in villages outside of Hyderabad, India, using extraoral, intraoral, and FV examinations. Lesion and normal tissue brushings were collected for DNA-ICM analysis and cytology. RESULTS: Of the 1116 participants screened, 184 lesions were observed in 152 participants. Based on white light examination (WLE), 45 lesions were recommended for biopsy. Thirty-five were completed on site; 25 (71%) were diagnosed with low-grade dysplasias (17 mild, 8 moderate) and the remaining 10 showed no signs of dysplasia. FV loss was noted in all but one dysplastic lesion and showed a sensitivity of 96% and specificity of 17%. Cytology combined with DNA-ICM had a sensitivity of 64% and specificity of 86% in detecting dysplasia. CONCLUSION: DNA-ICM combined with cytology identified the majority of dysplastic lesions and identified additional lesions, which were not considered high-risk during WLE and biopsy on site. Efforts to follow-up with these participants are ongoing. FV identified most high-risk lesions but added limited value over WLE.

Influence of nurse navigation on wait times for breast cancer care in a Canadian regional cancer center.

BACKGROUND: The wait times for breast cancer care in our region do not meet acceptable benchmarks. We implemented the Interior Breast Rapid Access Investigation and Diagnosis (IB-RAPID) nurse navigation program to address this issue. METHODS: The IB-RAPID prospective database was reviewed for patients entering the program between April 1, 2011 and April 30, 2012 (2011/2012 cohort), and was compared with patients from the same area in 2010. The main end point was the time between the 1st diagnostic imaging test and the surgery. Multiple linear regression was performed to investigate factors influencing the wait times. RESULTS: The wait times decreased with the introduction of IB-RAPID (59 vs 48 days; median). Stage of disease, total number of biopsies, and magnetic resonance imaging (MRI) use influenced wait times. MRI significantly delayed surgical intervention in both groups with those not having an MRI having a shorter wait time to surgery (68.5 vs 57.6 days; mean) in 2011/2012. CONCLUSION: The implementation of nurse navigation for patients with breast cancer appears to be effective at reducing the wait times for surgical treatment.

Controversies in acute stroke treatment.

The evidence base supporting the management of patients with acute stroke is evolving at a rapid rate, as new methods that aim to reduce disability and death from stroke are explored. Intravenous tissue plasminogen activator remains the only treatment shown in numerous studies to reduce disability 3 months after stroke with no increase in the risk of death and a relatively minor rate of symptomatic intracerebral hemorrhage complications. Despite these findings, health care providers have been slow to adopt this evidence-based treatment, which results in many patients experiencing disability caused by stroke. Numerous controversies exist related to the management of patients with acute stroke, including the use of tissue plasminogen activator, positioning and early mobility, blood pressure lowering in acute intracerebral hemorrhage, and even the use of innovative advanced practice nurse-led stroke treatment teams, with varying amounts of evidence available to provide direction. This article explores controversies associated with both approved and evolving treatments for ischemic and hemorrhagic stroke and makes recommendations for practice on the basis of the body of existing evidence, with an aim to improve the delivery of acute stroke treatment.

On the road again: patient perspectives on commuting for palliative care.

OBJECTIVE: The aim of this research project was to gain an understanding of the experiences of rural cancer patients who commute to an urban cancer center for palliative care. METHOD: The study utilized a mixed method design. Fifteen individuals with a palliative designation participated in semi-structured interviews and filled out the Problems and Needs in Palliative Care Questionnaire. RESULTS: Qualitative findings included three major themes: cultures of rural life and care, strategies for commuting, and the effects of commuting. Participants valued their rural lifestyles and gained significant support from their communities. Strategies included preparing for the trip with particular attention to pain management, making the most of time, and maintaining significant relationships. Establishing a routine helped to offset the anxiety of commuting. Commuting was costly but the quality of life and supportive relationships obtained through treatment were significant benefits. Questionnaire data suggested that participants were experiencing a number of problems but few indicated they desired more professional attention to those problems. SIGNIFICANCE OF RESULTS: Rural lifestyles are often an important part of overall well-being and commuting for care is both costly and complex. Health care providers should assist individuals to weigh the relative contributions of staying in their rural locale versus commuting for care to their overall quality of life. Palliative-care individuals in this study indicated a number of ongoing problems but were not inclined to seek further assistance from health care providers in addressing those problems. Clinicians should actively inquire about problems and further research is needed to understand why patients are reluctant to seek help.

Rural Palliative Care: A Comprehensive Review.

Abstract Background: Access to integrated, palliative care regardless of location of residence is a palliative care standard yet we know such access is limited for those living in rural and remote settings. As a beginning step in the development of research aimed at informing policy and program development, a comprehensive review of the state of knowledge regarding palliative care in rural contexts is required. Purpose: To identify, evaluate and synthesize the published literature on rural palliative care. Design: Comprehensive review. Methods: Computer searches were conducted on PubBMed, ISI Web of Science, PsycInfo, CINAHL, and Ageline using the search terms palliative care, hospice, terminal care, end-of-life care, end-of-life, and rural or remote. Results: One hundred fifty-eight studies were retrieved. After screening using relevance and quality criteria, 79 studies were included in the review. Studies were grouped by subject matter into one of three categories: patient and caregiver perspectives; professional attitudes, knowledge and practice issues; and health care services. Conclusion: The body of research literature is small and eclectic, which means there is little strong evidence to inform palliative policy and service development in rural settings. Coordinated programs of research are clearly required to develop a body of knowledge that is adequate to support effective service and policy development.
