The impact and effectiveness of faculty development program in fostering the faculty’s knowledge,skills, and professional competence: A systematic review and meta-analysis

BackgroundFaculty vitality is the main ingredient to enhance professional education and competence. Enriching the faculty vitality in key domains of teaching, assessing, research, professionalism, and administration is perceived to improve educational environment significantly and enhances the academic performance of learners. Faculty development program (FDP) has been considered as a stand-alone educational pedagogy in fostering knowledge and professional skills of faculty. However, few studies have provided objective reports about the impact of such programs in a healthcare system.MethodsThis research was conducted by selecting data sources of PubMed-Medline, Wiley online library, Cochrane library, Taylor & Francis Online, CINAHL, Springer link, Proquest, ISI Web of knowledge, ScienceDirect, EJS, EBSCO, Blackwell, Emerald and ABI Inform. This search followed a step-wise approach defined by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A total of 37 studies that explored the impact of FDPs on medical and allied health faculty’s professional development were selected.ResultsThis meta-analysis reported a mean effect size of 0.73 that reflects a significant and positive impact of FDPs in enhancing faculty’s knowledge and professional competence (z-statistics of 4.46 significant at p-value < 0.05) using the random effects model and forest plot.ConclusionThis article reiterates the incorporation of FDPs in all healthcare institutions for improving the academic performance of faculty with resultant enrichment of learners’ knowledge and skills.     

Human-specific LAIR2 contributes to the high invasiveness of human extravillous trophoblast cells

The placenta is a temporary vital organ for intra-uterine development and growth. The anatomical structure of the placenta has evolved substantially, resulting in broad inter-species diversity. In particular, human placental extravillous trophoblast cells (EVTs) have evolved aggressive features, although the mechanism underlying this aggressiveness remains elusive. In the present study, we compared the human and mouse homologous gene databases and obtained 2272 human-specific genes, 807 of which are expressed in the placenta according to the UniGene database. Using the human trophoblast cell line HTR8/SVneo, we further verified the expression and function of one of these genes, the leukocyte-associated immunoglobulin-like receptor 2 (LAIR2). This gene shows increased expression during pregnancy and its reduced expression is associated with pregnancy complications. Although LAIR2 was expressed in the human placenta villus and decidua in the first trimester of pregnancy, it was not expressed in mouse tissues. Knockdown of LAIR2 markedly improved cell viability and inhibited the invasive ability of HTR8/SVneo cells. These data suggest that species-specific genes are pivotal to the evolution of a more aggressive human placenta to match the physiological demands of human development. Further investigation is required to obtain evidence on the function of LAIR2 and other specific genes in the placenta, providing insight on the mechanism, properties, and possible applications of this in humans.
