Competency-based medical education (CBME) is gaining momentum across the globe. The Medical Council of India has described the basic competencies required of an Indian Medical Graduate and designed a competency-based module on attitudes and communication. Widespread adoption of a competency-based approach would mean a paradigm shift in the current approach to medical education. CBME, hence, needs to be reviewed for its usefulness and limitations in the Indian context. This article describes the rationale of CBME and provides an overview of its components, i.e., competency, entrustable professional activity, and milestones. It elaborates how CBME could be implemented in an institute, in the context of basic sciences in general and pharmacology in particular. The promises and perils of CBME that need to be kept in mind to maximize its gains are described.

Purpose To evaluate by sequential 18F-FDG PET/CT imaging the therapeutic response to a novel monoclonal antibody targeting human EMMPRIN (extracellular matrix metalloproteinase inducer) in combination with gemcitabine in a pancreatic-tumor xenograft murine model. Procedures Four groups of SCID mice bearing orthotopic pancreatic tumor xenografts were injected with PBS, gemcitabine (120mg/kg BW), anti-EMMPRIN antibody (0.2mg), or combination, respectively twice weekly for 2 weeks, while 18F-FDG PET/CT imaging was performed weekly for 3 weeks. Changes in mean standardized uptake value (SUVmean) of 18F-FDG and volume of tumors were determined. Results The tumor SUVmean change in the group receiving combination therapy was significantly lower than those of the other groups. Tumor-volume changes of groups treated with anti-EMMPRIN monotherapy or combined therapy were significantly lower than that of the control group. Conclusions These data provide support for clinical studies of anti-EMMPRIN therapy with gemcitabine for pancreatic cancer treatment.
The objective of this study was to evaluate extracelluar matrix metalloproteinase (EMMPRIN) as a novel target in orthotopic pancreatic-cancer murine models. MIA PaCa-2 human pancreatic tumor cells were implanted in groups 1 and 3-7, while MIA PaCa-2 EMMPRIN knockdown cells were implanted in group 2. Dosing with anti-EMMPRIN antibody started immediately after implantation for groups 1-3 (residual tumor model) and at 21 days after cell implantation for groups 4-7 (established tumor model). Groups 3, 5, and 7 were treated with anti-EMMRPIN antibody (0.2-1.0 mg) twice weekly for 2-3 weeks, while the other groups served as the control. In residual tumor model, tumor growth of anti-EMMPRIN treated group was successfully arrested for 21 days (15±4 mm3), significantly lower than that of EMMPRIN knockdown group (80±15 mm3; p=0.001) or control group (240±41 mm3; p<0.001). In established tumor model, anti-EMMPRIN therapy lowered tumor-volume increase about 40% compared with control regardless of dose amount. Ki67-expressed cell densities of group 5 was 939±150 mm−2, significantly lower than that of group 4 (1709±145 mm−2; p=0.006). Microvessel density of group 5 (30±6 mm−2) was also significantly lower than that of group 4 (53±5 mm−2; p=0.014), while the microvessel size of group 5 (191±22 μm2) was significantly larger than that of group 4 (113±26 μm2; p=0.049). These data show the high potential of anti-EMMPRIN therapy for pancreatic cancer, and support its clinical translation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
