Effectiveness and experiences of team-based learning in nurse education programs: a mixed methods systematic review protocol.

REVIEW OBJECTIVES/QUESTIONS: The objective of this mixed methods systematic review is to develop an integrated synthesis of quantitative and qualitative research evidence on team-based learning (TBL) in undergraduate nurse education programs to inform active learning strategies among students.More specifically, the objectives are.

A Comparison of Discovered Regularities in Blood Glucose Readings across Two Data Collection Approaches Used with a Type 1 Diabetic Youth.

BACKGROUND: Type 1 diabetes requires frequent testing and monitoring of blood glucose levels in order to determine appropriate type and dosage of insulin administration. This can lead to thousands of individual measurements over the course of a lifetime of a single individual, of which very few are retained as part of a permanent record. The third author, aged 9, and his family have maintained several years of written records since his diagnosis with Type 1 diabetes at age 20 months, and have also recently begun to obtain automated records from a continuous glucose monitor. OBJECTIVES: This paper compares regularities identified within aggregated manually-collected and automatically-collected blood glucose data visualizations by the family involved in monitoring the third author's diabetes. METHODS: 7,437 handwritten entries of the third author's blood sugar readings were obtained from a personal archive, digitized, and visualized in Tableau data visualization software. 6,420 automatically collected entries from a Dexcom G4 Platinum continuous glucose monitor were obtained and visualized in Dexcom's Clarity data visualization report tool. The family was interviewed three times about diabetes data management and their impressions of data as presented in data visualizations. Interviews were audiorecorded or recorded with handwritten notes. RESULTS: The aggregated visualization of manually-collected data revealed consistent habitual times of day when blood sugar measurements were obtained. The family was not fully aware that their existing life routines and the third author's entry into formal schooling had created critical blind spots in their data that were often unmeasured. This was realized upon aggregate visualization of CGM data, but the discovery and use of these visualizations were not realized until a new healthcare provider required the family to find and use them. The lack of use of CGM aggregate visualization was reportedly because the default data displays seemed to provide already abundant information for in-the-moment decision making for diabetes management. CONCLUSIONS: Existing family routines and school schedules can shape if and when blood glucose data are obtained for T1D youth. These routines may inadvertently introduce blind spots in data, even when it is collected and recorded systematically. Although CGM data may be superior in its overall density of data collection, families do not necessarily discover nor use the full range of useful data visualization features. To support greater awareness of youth blood sugar levels, families that manually obtain youth glucose data should be advised to avoid inadvertently creating data blind spots due to existing schedules and routines. For families using CGM technology, designers and healthcare providers should consider implementing better cues and prompts that will encourage families to discover and utilize aggregate data visualization capabilities.

Efficient isolation of genes differentially expressed on cellulose by suppression subtractive hybridization in Agaricus bisporus.

The production of cellulases on minimal medium in the edible mushroom Agaricus bisporus is regulated by the carbon source: induced by cellulose and repressed by glucose. In order to isolate cellulose-growth specific sequences, a cDNA library from A. bisporus using suppression subtractive hybridization (SSH) was constructed. Northern blot analysis indicated that a high level of enrichment was achieved; 183 clones were isolated. A preliminary screen with cellulose-specific genes of A. bisporus (cel1, cel2, cel3 and cel4) using Southern hybridization resulted in 28 clones to be cel3, and 5 clones were cel2. The remaining 144 clones were sequenced. Partial sequences of the following genes were found: a beta-glucosidase homologue of the blvk gene of Kluyveromyces marxianus; a cellulase homologue of an endoglucanase (avicellase III) of Aspergillus aculeatus, four different xylanases homologue of the xyn genes of different fungi, and one hexose transporter homologue to the hxtA gene of Aspergillus parasiticus. The apparent full-length of two hydrophobins homologue to the abh3 gene of A. bisporus and one histone homologue to the h2a gene of Aspergillus niger were also found. The remaining sequences did not have homology to any known genes.
