On-line capacity-building program on "analysis of data" for medical educators in the South Asia region: a qualitative exploration of our experience

BACKGROUND AND OBJECTIVE

In medical education, using the World Wide Web is a new approach for building the capacity of faculty. However, there is little information available on medical education researchers' needs and their collective learning outcomes in such on-line environments. Hence, the present study attempted: 1)to identify needs for capacity-building of fellows in a faculty development program on the topic of data analysis; and 2) to describe, analyze and understand the collective learning outcomes of the fellows during this need-based on-line session.

MATERIALS AND METHODS

The present research is based on quantitative (on-line survey for needs assessment) and qualitative (contents of e-mails exchanged in listserv discussion) data which were generated during the October 2009 Mentoring and Learning (M-L) Web discussion on the topic of data analysis. The data sources were shared e-mail responses during the process of planning and executing the M-L Web discussion. Content analysis was undertaken and the categories of discussion were presented as a simple non-hierarchical typology which represents the collective learning of the project fellows.

RESULTS

We identified the types of learning needs on the topic 'Analysis of Data' to be addressed for faculty development in the field of education research. This need-based M-L Web discussion could then facilitate collective learning on such topics as 'basic concepts in statistics', tests of significance, Likert scale analysis, bivariate correlation, and simple regression analysis and content analysis of qualitative data.

CONCLUSIONS

Steps like identifying the learning needs for an on-line M-L Web discussion, addressing the immediate needs of learners and creating a flexible reflective learning environment on the M-L Web facilitated the collective learning of the fellows on the topic of data analysis. Our outcomes can be useful in the design of on-line pedagogical strategies for supporting research in medical education.

Exocrine pancreatic function (serum immunoreactive trypsin, fecal chymotrypsin, and pancreatic isoamylase) in Indian diabetics

Forty-nine patients with tropical calcific pancreatitis (TCP), 51 insulin-dependent diabetics (IDDMs), 87 non-insulin-dependent diabetics (NID-DMs), and 66 nondiabetic controls were studied to evaluate their exocrine pancreatic function by measurement of serum immunoreactive trypsin (IRT, normal for white caucasians from the U.K. of 140-414 micrograms/L), pancreatic isoamylase (PIA, normal of 35-125 U/L), and fecal chymotrypsin (FCT, normal of greater than 6.6 u/g). The majority of patients were studied within 1 year of diagnosis. TCP subjects included 7 nondiabetics, 6 with impaired glucose tolerance (IGT-TCP), and 36 diabetics [fibrocalculous pancreatic diabetes (FCPD)]. There was evidence of active pancreatitis (IRT greater than 800 micrograms/L) and partial preservation of function in nondiabetic TCP subjects [median IRT of 220 micrograms/L (range of 102-1,360 micrograms/L), FCT of 2.2 u/g (range 0.7-12.8 u/g)] and also in IGT-TCP subjects [IRT of 370 micrograms/L (range of 30-1,360 micrograms/L), FCT of 4.2 u/g (range of 1-38 u/g)]. FCPDs showed severely diminished exocrine function [IRT of 50 micrograms/L (range of 0-184 micrograms/L), FCT of 0.23 u/g (range of 0-10.4 u/g)]; none showed IRT greater than 800 micrograms/L. IDDMs and NIDDMs also showed diminished exocrine pancreatic function in approximately 30 and approximately 10%, respectively. Controls showed a wide range of IRT and FCT concentrations; IRT concentrations tended to be higher than those reported in white Caucasians from the U.K. Three controls, one IDDM, and two NIDDMs showed "pancreatic" IRT concentrations in the absence of symptoms. PIA concentrations were diminished in FCPD but were similar in IDDM and NIDDM subjects compared to controls.(ABSTRACT TRUNCATED AT 250 WORDS)

The spectrum of pancreatic exocrine and endocrine (beta-cell) function in tropical calcific pancreatitis

Exocrine pancreatic marker (immunoreactive-trypsin) and endocrine Beta-cell function (plasma insulin and C-peptide during an oral glucose tolerance test) were studied in 40 subjects with tropical-calcific-pancreatitis [seven non-diabetic, seven with impaired-glucose-tolerance and 26 diabetic (fibro-calculous-pancreatic-diabetes)]. In non-diabetic and impaired-glucose-tolerance subjects there was evidence of active pancreatitis in some and exocrine function was partially preserved. Fibro-calculous-pancreatic-diabetic subjects showed severely diminished exocrine pancreatic function; none showed 'pancreatitic' elevation of immunoreactive-trypsin. Beta-cell function was preserved in non-diabetic and impaired-glucose-tolerance subjects; diabetic subjects showed variable Beta-cell function but it was severely diminished in more than 75%. Immunoreactive-trypsin and C-peptide were directly correlated (rs = 0.55, p less than 0.01). This cross sectional study demonstrates, for the first time, that the Beta-cell loss in tropical-calcific-pancreatitis is related to the exocrine loss. It suggests that diabetes in tropical-calcific-pancreatitis is either secondary to pancreatitis or that a common factor(s) acts simultaneously on both components.
