Developing an organizing framework to guide nursing research in the Children’s Oncology Group (COG)

Objectives To describe the development and application of an organizing research framework to guide COG Nursing research. Data Sources Research articles, reports and meeting minutes Conclusion An organizing research framework helps to outline research focus and articulate the scientific knowledge being produced by nurses in the pediatric cooperative group. Implication for Nursing Practice The use of an organizing framework for COG nursing research can facilitate clinical nurses’ understanding of how children and families sustain or regain optimal health when faced with a pediatric cancer diagnosis through interventions designed to promote individual and family resilience., The Children’s Oncology Group (COG) is the sole National Cancer Institute (NCI)-supported cooperative pediatric oncology clinical trials group and the largest organization in the world devoted exclusively to pediatric cancer research. It was founded in 2000 following the merger of the four legacy NCI-supported pediatric clinical trials groups (Children’s Cancer Group [CCG], Pediatric Oncology Group [POG], National Wilms Tumor Study Group, and Intergroup Rhabdomyosarcoma Study Group). The COG currently has over 200 member institutions across North America, Australia, New Zealand and Europe and a multidisciplinary membership of over 8,000 pediatric, radiation, and surgical oncologists, nurses, clinical research associates, pharmacists, behavioral scientists, pathologists, laboratory scientists, patient/parent advocates and other pediatric cancer specialists. The COG Nursing Discipline was formed from the merger of the legacy CCG and POG Nursing Committees, and current membership exceeds 2000 registered nurses. The discipline has a well-developed infrastructure that promotes nursing involvement throughout all levels of the organization, including representation on disease, protocol, scientific, executive and other administrative committees (e.g., nominating committee, data safety monitoring boards). COG nurses facilitate delivery of protocol-based treatments for children enrolled on COG protocols, and Nursing Discipline initiatives support nursing research, professional and patient/family education, evidence-based practice, and a patient-reported outcomes resource center. The research agenda of the Nursing Discipline is enacted through a well-established nursing scholar program

Anti-Stokes luminescence cooling of Tm3+ doped BaY2F8

We report laser-induced cooling with thulium-doped BaY2F8 single crystals grown using the Czochralski technique. The spectroscopic characterization of the crystals has been used to evaluate the laser cooling performance of the samples. Cooling by 3 degrees below ambient temperature is obtained in a single-pass geometry with 4.4 Watts of pump laser power at lambda = 1855 nm

Safety of dietary camelina oil supplementation in healthy, adult dogs

This study aimed to determine whether camelina oil is safe for use in canine diets, using canola oil and flax oil as controls, as they are similar and generally regarded as safe (GRAS) for canine diets. A total of thirty privately-owned adult dogs of various breeds (17 females; 13 males), with an average age of 7.2 ± 3.1 years (mean ± SD) and a body weight (BW) of 27.4 ± 14.0 kg were used. After a 4-week wash-in period using sunflower oil and kibble, the dogs were blocked by breed, age, and size and were randomly allocated to one of three treatment oils (camelina (CAM), flax (FLX), or canola (OLA)) at a level of 8.2 g oil/100 g total dietary intake. Body condition score (BCS), BW, food intake (FI), and hematological and select biochemical parameters were measured at various timepoints over a 16-week feeding period. All of the data were analyzed with ANOVA using the PROC GLIMMIX of SAS. No biologically significant differences were seen between the treatment groups in terms of BW, BCS, FI, and hematological and biochemical results. Statistically significant differences noted among some serum biochemical results were considered small and were due to normal biological variation. These results support the conclusion that camelina oil is safe for use in canine nutrition

Validating a Shortened Depression Scale (10 Item CES-D) among HIV-Positive People in British Columbia, Canada

Objective To establish the reliability and validity of a shortened (10-item) depression scale used among HIV-positive patients enrolled in the Drug Treatment Program in British Columbia, Canada. Methods The 10-item CES-D (Center for Epidemiologic Studies Depression Scale) was examined among 563 participants who initiated antiretroviral therapy (ART) between August 1, 1996 and June 30, 2002. Internal consistency of the scale was measured by Cronbach’s alpha. Using the original CES-D 20 as primary criteria, comparisons were made using the Kappa statistic. Predictive accuracy of CES-D 10 was assessed by calculating sensitivity, specificity, positive predictive values and negative predictive values. Factor analysis was also performed to determine if the CES-D 10 contained the same factors of positive and negative affect found in the original development of the CES-D. Results The correlation between the original and the shortened scale is very high (Spearman correlation coefficient = 0.97 (P<0.001). Internal consistency reliability coefficients of the CES-D 10 were satisfactory (Cronbach α = 0.88). The CES-D 10 showed comparable accuracy to the original CES-D 20 in classifying participants with depressive symptoms (Kappa = 0.82, P<0.001). Sensitivity of CES-D 10 was 91%; specificity was 92%; and positive predictive value was 92%. Factor analysis demonstrates that CES-D 10 contains the same underlying factors of positive and negative affect found in the original development of the CES-D 20. Conclusion The 10-item CES-D is a comparable tool to measure depressive symptoms among HIV-positive research participants

A Bibliometric Analysis of Select Information Science Print and Electronic Journals in the 1990s

This paper examines three e-journals and one paper journal begun in the 1990s within the information science genre. In addition, these journals are compared to what is perhaps the leading information science journal, one that has been published continuously for fifty years. The journals we examine are CyberMetrics, Information Research, the Journal of Internet Cataloging, Libres, and the Journal of the American Society for Information Science. We find that there are a number of important differences among the journals. These include frequency of publication, publication size, number of authors, and the funding status of articles. We also find differences among journals for distributions of authors by gender and corporate authors by region. Some of the regional differences can be explained by journal maturation -- the more mature the journal the greater the dispersion. We also find that women are more likely to publish in the newer journals than in JASIS. The fact that a journal is or is not an e-journal does not appear to affect its presence or behaviour as an information science journal

Physical Activity Levels of Patients Undergoing Bariatric Surgery in the Longitudinal Assessment of Bariatric Surgery (LABS) Study

Background- Bariatric surgery candidates' physical activity (PA) level may contribute to the variability of weight loss and body composition changes following bariatric surgery. However, there is little research describing the PA of patients undergoing bariatric surgery to inform PA recommendations in preparation for, and following, surgery. Objectives- Describe PA assessment in the LABS-2 study and report pre-surgery PA level. Examine relationships between objectively determined PA level and 1) BMI and 2) self-reported purposeful exercise. Setting- Six sites in the U.S. Methods- Participants wore an accelerometer and completed a PA diary. Standardized measures of height and weight were obtained. Results- Of 757 participants, 20% were sedentary (<5000 steps/day), 34% low active (5000-7499 steps/day), 27% somewhat active (7500-9999 steps/day), 14% active (10000-12499 steps/day), and 6% were highly active (greater than or equal to 12500 steps/day). BMI was inversely related to mean steps/day and mean steps/minute during the most active 30 minutes each day. The most commonly reported activities were walking, 44%; gardening, 11%; playing with children, 10%; and stretching, 7%. Self-report of minutes of exercise accounted for 2% of the variance in objectively determined steps. Conclusion- Patients present for bariatric surgery with a wide range of PA levels, with almost half categorized as somewhat active or active. BMI is inversely related to total amount and intensity of PA. Few patients report a regular pre-operative exercise regimen suggesting most PA is accumulated from activities of daily living. Patient report of daily minutes of walking or exercise may not be a reliable indication of their PA level. Originally published Surgery for Obesity and Related Diseases, Vol. 4, No. 6, Nov-Dec 200

Intracranial hypotension secondary to spinal arachnoid cyst rupture presenting with acute severe headache: a case report

<p>Abstract</p> <p>Introduction</p> <p>Headache is a common presenting complaint and has a wide differential diagnosis. Clinicians need to be alert to clues that may suggest an underlying secondary aetiology. We describe a novel case of headache secondary to intracranial hypotension which was precipitated by the rupture of a spinal arachnoid cyst.</p> <p>Case report</p> <p>A 51-year-old Indian female presented with sudden onset severe headache suggestive of a subarachnoid haemorrage. Investigations including a computed tomography brain scan, cerebrospinal fluid examination and a magnetic resonance angiogram were normal. The headache persisted and magnetic resonance imaging revealed bilateral thin subdural collections, a spinal subarachnoid cyst and a right-sided pleural effusion. This was consistent with a diagnosis of headache secondary to intracranial hypotension resulting from spinal arachnoid cyst rupture.</p> <p>Conclusions</p> <p>Spinal arachnoid cyst rupture is a rare cause of spontaneous intracranial hypotension. Spontaneous intracranial hypotension is a common yet under-diagnosed heterogeneous condition. It should feature significantly in the differential diagnosis of patients with new-onset daily persistent headache.</p
