Assessment of training needs and preferences for geographic information systems (GIS) mapping in state comprehensive cancer-control programs

Geographic information systems (GIS) mapping technologies have potential to advance public health promotion by mapping regional differences in attributes (e.g., disease burden, environmental exposures, access to health care services) to suggest priorities for public health interventions. Training in GIS for comprehensive cancer control (CCC) has been overlooked. State CCC programs' GIS training needs were assessed by interviewing 49 state CCC directors. A majority perceived a need for GIS training, slightly more than half of state CCC programs had access to geocoded data, and the majority of programs did not require continuing education credits of their staff. CCC directors perceived judging maps and realizing their limitations as important skills and identified epidemiologists, CCC staff, public health officials, policy makers, and cancer coalition members as training audiences. They preferred in-class training sessions that last a few hours to a day. Lessons learned are shared to develop training programs with translatable GIS skills for CCC.     

Enhanced chemotherapy delivery by intraarterial infusion and blood-brain barrier disruption in the treatment of cerebral metastasis

BACKGROUND: Cerebral metastases are clinically significant in 10% to 30% of patients with neoplasia. Multiple cerebral metastases are typically treated with palliative radiotherapy. There is no consensus on the role of enhanced chemotherapy delivery as an adjuvant treatment modality in this disease. In this report, the authors detailed their experience with intraarterial (IA) chemotherapy infusion with and without blood-brain barrier disruption (BBBD) in patients with multiple cerebral metastases. METHODS: From November 1999 to May 2005, 38 patients with multiple cerebral metastases were enrolled in a prospective study. Patients were treated with IA carboplatin, except for those with cerebral metastases of systemic lymphoma, who were administered IA methotrexate. Osmotic BBBD was offered to patients without the presence of a significant mass effect. These regimens were coupled with intravenous etoposide and cyclophosphamide. Cycles were repeated every 4 weeks. RESULTS: Survival was calculated from study entry and radiologic response was based on MacDonald criteria. Kaplan-Meier estimates were generated for all subgroups. Mean and median survival obtained was as follows: 34 and 29.6 months for the whole group; 33.6 and 42.3 months for ovarian carcinoma; 15.3 and 13.5 months for lung adenocarcinomas; 8.3 and 8.8 months for small cell lung carcinoma; 8.9 and 8.1 months for breast carcinoma; and 24.8 and 16.3 months, respectively, for cerebral metastasis from systemic lymphoma. CONCLUSIONS: Even with a small number of patients in each subgroup, the results obtained seem promising for multiple brain metastasis of ovarian carcinoma, adenocarcinoma of lung, small cell lung carcinoma, and systemic lymphoma.     

Healthcare experiences of patients with Down syndrome who are Black,African American,of African descent,or of mixed race

Scant research has explored the healthcare experiences of people with Down syndrome (DS) in the United States who are Black, African American, of African descent, or of mixed race. The purpose of this study was to identify and describe the barriers and facilitators that such patients and their caregivers face when accessing healthcare. We gathered data in three ways: focus groups with caregivers, a national survey completed by caregivers, and in-depth interviews with primary care providers. Many caregivers and primary care physicians felt that patients with DS who are Black, African American, of African descent, or of mixed race receive a lower quality of medical care than their white counterparts with DS. Caregivers mentioned feeling tired of being reminded by the medical community about their race and wanting acknowledgment that raising a child with DS can be hard at times. Many felt that the medical community's conscious and unconscious racial biases do negatively impact the care of their loved ones with DS. Caregivers desired more race concordant medical providers or, when not possible, medical providers who are willing to learn more about DS and build trusted, longitudinal relationships. Primary care providers discussed the need for funded resources and support services to effectively care for their patients with DS.     

A Multivariate Validation of the Defining Characteristics of Fatigue

PURPOSE. To validate the nursing diagnosis fatigue by providing evidence to identify, confirm, and consolidate the defining characteristics.
METHODS. The Revised Piper Fatigue Scale and the Schwartz Measurement of Fatigue scales were used to collect data from four groups of healthy women (N = 182). Data were analyzed by maximum-likelihood factor analysis with varimax rotation, and major and minor defining characteristics were identified and clustered.
FINDINGS. The identified defining characteristics tended to group into the dimensions identified in prior fatigue studies. Although the majority of the NANDA defining characteristics were validated, differences were found.
CONCLUSIONS. atigue is a multidimensional construct. Replication of the study with a variety of samples from different geographic locations and a variety of patient populations will further cross-validate the defining characteristics of fatigue.
PRACTICE IMPLICATIONS. Fatigue is a commonly experienced phenomenon in both health and illness. As the knowledge base about fatigue builds, so will the accuracy of nursing assessments and the effectiveness of nursing interventions.     

Varicella zoster meningitis in a pregnant woman with acquired immunodeficiency syndrome

Between 6000 and 7000 women in the United States infected with human immunodeficiency virus (HIV) give birth annually. It is well known that HIV-related immunosuppression significantly increases the risk for acquiring opportunistic infections (OIs). However, there is limited information regarding the relationship of pregnancy in the setting of HIV/AIDS infection, subsequent development of OIs, and maternal and fetal outcomes. A pregnant 36-year-old woman with AIDS was diagnosed with varicella zoster meningitis. Weight-based therapy with acyclovir was initiated with clinical improvement in symptoms. Care of a pregnant HIV-infected patient with an OI poses a unique diagnostic and therapeutic challenge for clinicians. Early diagnosis and initiation of appropriate treatment may provide an opportunity to improve both maternal and fetal outcomes.     

Mouse cells surviving polyoma virus infection generally retain the whole viral genome

Permissive mouse 3T6 cells were exposed to polyoma virus--either wild-type or early mutant--at high multiplicities of infection. From colonies arising from surviving cells, so-called lines and clones were derived under conditions precluding superinfection. These lines and clones were examined for the presence of viral genetic information, using a variety of techniques. Two salient findings were made: most lines or clones analyzed had retained viral genetic material; generally, this material was nondefective, as evidenced by the production of virus and/or viral DNA molecules of genomic size. These findings indicate that mouse cells can survive for many generations while carrying a complete, infectious, and potentially cytocidal polyoma virus genome.
