The evolution of a quality improvement curriculum in a family nurse practitioner residency program.

There is a wide variation in the curricular emphasis and implementation nationally across programs for teaching quality improvement (QI) in family nurse practitioner (FNP) programs. This variation among curriculum plans often leaves NP graduates unsure as to how to identify and effect change within their organizations. This manuscript describes the development of an initial QI curriculum and subsequent enhancements over a 3-year time frame and outlines the curriculum development process, implementation, and program outcomes within an FNP residency program.

Beyond competence and retention: Developing a comprehensive evaluation framework for a rural primary care nurse practitioner residency program.

With the rise in nurse practitioner (NP) residency programs, evaluations have largely focused on retention and competency completion for residents. There is a need for expanded evaluation to ensure the sustainability of NP residency programs, to ensure timely adaptations to address resident satisfaction, and to solidify a long-term pathway of NPs well prepared for rural practice. We created a family nurse practitioner (FNP) residency program with a comprehensive evaluation framework to prepare residents for practice in rural settings.

Relative fitness of susceptible and Cry1A.105/Cry2Ab2-single-/dual-protein-resistant Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae) on non-Bt diet and a diet containing a low concentration of two proteins.

Cry75Aa (Mpp75Aa) Insecticidal Proteins for Controlling the Western Corn Rootworm, , (Coleoptera: Chrysomelidae), Isolated from the Insect Pathogenic Bacteria .

This study describes three closely related proteins, cloned from strains, that are lethal upon feeding to LeConte, the western corn rootworm (WCR). Mpp75Aa1, Mpp75Aa2 and Mpp75Aa3 were toxic to WCR larvae when fed purified protein. Transgenic plants expressing each mMpp75Aa protein were protected from feeding damage and showed significant reduction in adult emergence from infested plants by both susceptible and Cry3Bb1 and Cry34Ab1/Cry35Ab1-resistant WCR.

A new Bacillus thuringiensis protein for Western corn rootworm control.

The Western corn rootworm (WCR) Diabrotica virgifera virgifera LeConte is one of the most economically important insect pests in North America. Since 2003, transgenic maize expressing WCR-active proteins from Bacillus thuringiensis (Bt) have been widely adopted as the main approach to controlling WCR in the U.S.

Performance of Bt-susceptible and -heterozygous dual-gene resistant genotypes of Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) in seed blends of non-Bt and pyramided Bt maize.

Physical activity impacts insulin sensitivity post metabolic bariatric surgery in adolescents with severe obesity.

Background/objectives: We hypothesized that physical activity (PA) improves insulin sensitivity in adolescents with severe obesity beyond that attributable to metabolic bariatric surgery (MBS).

Subjects/methods: StepWatch monitors objectively measured PA in 88 participants in the Teen Longitudinal Assessment of Bariatric Surgery (Teen-LABS) study. Primary outcomes included absolute change in fasting insulin, HOMA-IR, and fasting glucose from pre-surgery (baseline) to 6, 12, 24, and 36 months post-MBS.

Inheritance of Bacillus thuringiensis Cry2Ab2 protein resistance in Helicoverpa zea (Lepidoptera: Noctuidae).

Background: The corn earworm, Helicoverpa zea (Boddie), is a major target pest of pyramided Bt corn and cotton in the United States. Field-evolved practical resistance to Cry1 and Cry2 proteins in H. zea has been documented in multiple locations in the United States.

Extended evaluation of Bt protein cross-pollination in seed blend plantings on survival, growth, and development of Helicoverpa zea feeding on refuge ears.

Background: A seed blend, also called refuge in a bag (RIB), is used as a strategy to provide refuge for planting pyramided Bt corn in the U.S. Corn Belt.

Physical Activity Improves Lipid and Weight-Loss Outcomes After Metabolic Bariatric Surgery in Adolescents with Severe Obesity.

Objective: This study tested the hypothesis that physical activity improves cardiovascular disease-related lipids beyond that associated with weight loss in adolescents with severe obesity after metabolic/bariatric surgery (MBS).

Methods: Objective activity monitor data from 108 participants of the Teen Longitudinal Assessment of Bariatric Surgery (Teen-LABS) study from baseline to 3 years post MBS were used. Primary outcomes included absolute change in LDL cholesterol (LDL-C) and non-HDL cholesterol (non-HDL-C) from baseline.

We simulated larval feeding behavior in seed blends of non-Bt and Bt maize to determine if seed blends create more favorable conditions for heterozygous-resistant insects over their Bt-susceptible counterparts. Survival, growth, development, and progeny production of four genotypes of the fall armyworm, Spodoptera frugiperda, Bt-susceptible (aabb), Cry1A.105 heterozygous resistant (Aabb), Cry2Ab2 heterozygous resistant (aaBb), and Cry1A.

Background: Fall armyworm, Spodoptera frugiperda, is a major target pest of the Vip3A protein. The fitness of Bacillus thuringiensis (Bt)-resistant insects on refuges is an important factor in determining the speed of resistance development. Fitness costs associated with Bt resistance can vary among host plants.

Background: Gene-pyramiding by combining two or more dissimilar Bacillus thuringiensis (Bt) proteins into a crop has been used to delay insect resistance. The durability of gene-pyramiding can be reduced by cross-resistance. Fall armyworm, Spodoptera frugiperda, is a major target pest of the Cry2Ab2 protein used in pyramided Bt corn and cotton.

Cry3Bb1-Resistant Western Corn Rootworm, Diabrotica virgifera virgifera (LeConte) Does Not Exhibit Cross-Resistance to DvSnf7 dsRNA.

Background And Methodology: There is a continuing need to express new insect control compounds in transgenic maize against western corn rootworm, Diabrotica virgifera virgifera (LeConte) (WCR). In this study three experiments were conducted to determine cross-resistance between the new insecticidal DvSnf7 dsRNA, and Bacillus thuringiensis (Bt) Cry3Bb1; used to control WCR since 2003, with field-evolved resistance being reported. Laboratory susceptible and Cry3Bb1-resistant WCR were evaluated against DvSnf7 dsRNA in larval diet-incorporation bioassays.
