Systematic review: Predictors of students' success in baccalaureate nursing programs.

Nursing schools strive to select a diverse student population who are likely to succeed by ensuring timely student progression through the program and effective use of educational sources. The purpose of this systematic literature review is to explore the preadmission variables and selection criteria that predict student success in 4-year baccalaureate nursing programs in the U.S. Sixteen articles met the eligibility criteria, and six measures were used to define student success: (a) early academic success, particularly during the first and second year; (b) attrition; (c) timely completion of the program; (d) graduation; (e) performance in nursing courses; and (f) academic performance in other science courses. Typically, the core set of cognitive predictors used in the admission process in nursing schools were pre-nursing GPA, pre-nursing collegiate science GPA, and scores on standardized aptitude exams. This review suggests that it is challenging to isolate one single variable as the best predictor of student success; however, using a combination of variables can offer a reliable prediction method. More researchers should consider using a theoretical basis to guide their inquiry on this topic. Additionally, researchers should examine admission variables that are most relevant across programs.

Systematic review of program evaluation in baccalaureate nursing programs.

Program evaluation is a common practice in nursing education programs; however, evidence indicates that many schools only focus on program evaluation around the scheduled accreditation period, thus reducing the potential value of the evaluation. This systematic review explores the current program evaluation practices of prelicensure baccalaureate nursing programs. ERIC, CINAHL, and Scopus databases were searched to locate original research articles published in English. Twenty articles met the inclusion criteria. The purposes of the evaluated studies varied from needing to meet external accountability requirements to proposing conceptual frameworks and evaluation tools. However, most studies focused on summative evaluation assessing program products and on providing evidence of program evaluation based on descriptive data. Notably, few studies employed a rigorous method to evaluate and interpret program evaluation findings. Most studies solicited information from multiple stakeholder groups, with students being the most represented. Despite the wide range of data collection tools used in the reviewed studies, reporting of validity and reliability was limited. Student grade point average, graduation rate, NCLEX passing rate, and satisfaction with the learning experience were the most common variables. Further studies are needed to assess the effectiveness of current educational program evaluation practices in nursing education.

Antifibrotic and tumor microenvironment modulating effect of date palm fruit (Phoenix dactylifera L.) extracts in pancreatic cancer.

Date palm fruit (Phoenix dactylifera L.) is an endemic functional food, with great nutritional and economic importance due to its phytochemical compositions. The microenvironment of pancreatic cancer consists of cellular and acellular components, including fibroblasts, myofibroblasts, pancreatic stellate cells (PSCs), immune cells, blood vessels, extracellular matrix (ECM) and soluble proteins, such as cytokines and growth factors. The ECM represents a physical barrier that protects the tumor cell from active therapeutic compounds. In this study, four different solvents; water, ethanol, acetone, and ethyl acetate have been used to extract natural products from date palm fruit using a maceration method. The prepared extracts were investigated for antifibrotic (expression of fibronectin-1 and alpha-smooth muscle actin) and antiproliferative activity in tumor necrosis factor (TNF) stimulated PSCs in vitro. Based on the pharmacological test results, the ethyl acetate extract was subsequently partitioned into nine fractions based on polarity using silica gel column chromatography. These nine collective fractions were further evaluated for their activity. Ethanol, ethyl acetate and acetone, but not water extract significantly reduced PSC proliferation (p < 0.05). Date fruit fractions reduced fibrosis, decreased PSC activity and reversed the PSCs' fibrotic phenotype. The findings suggest a new approach for targeting pancreatic cancer through the modulation of PSC activity, thereby possibly enhancing the effect of known anticancer drugs. Moreover, date palm fruit appears to have chemopreventive activity protecting from pancreatic and probably other types of cancer, and thereby might be useful candidate to the pharmaceutical and nutraceutical industries in the development of natural compound-based industrial anticancer product.

Date Palm Tree (Phoenix dactylifera L.): Natural Products and Therapeutic Options.

Many plants, including some of the commonly consumed herbs and spices in our daily food, can be safely and effectively used to prevent and/or treat some health concerns. For example, caffeine the active ingredient found in coffee beans (Coffea), shows biological activity in the treatment of the central nervous system (CNS) disorders, indole-3-carbinol, and 3,3'-diindolylmethane are both broccoli (Brassica oleracea) derived phytochemicals with potential anti-cancer activity, and resveratrol, isolated from grape (Vitis vinifera), is reported to extend lifespan and provide cardio-neuro-protective, anti-diabetic, and anti-cancer effects. Date palm fruits possess high nutritional and therapeutic value with significant antioxidant, antibacterial, antifungal, and anti-proliferative properties. This review focuses on the date fruit extracts and their benefits in individual health promoting conditions and highlights their applications as useful to the pharmaceutical and nutraceutical industries in the development of natural compound-based industrial products.
