Background: Medical Ethics (ME) is considered an integral component of medical education around the world. However, limited training is being offered to medical students in Pakistan. Objectives: This study was designed to evaluate medical students' perspectives regarding medical ethics and to explore their experiences about medical ethics as a subject at a private medical college in Lahore, where Medical Ethics was formally introduced as part of the undergraduate curriculum in 2017. Methods: This mixed-method study included medical students from all five years of medical college. Quantitative component included a survey questionnaire, and the sample size was 410. Convenient sampling technique was used. Qualitative component included focus group discussions. The students who have attended medical ethics lectures were included in the study. Results: The response rate was 82.72%. There were more females in gender distribution; 76.1% were female and 23.9% were male. Most respondents (74.9%) found medical ethics classes interesting and 72% thought that lecture sessions were important in medical ethics. Conclusions: Medical students find medical ethics as an important component of medical education. Although it is hard to correlate ethics education with their clinical experience as medical students, they believe that medical ethics education can be useful. Social and cultural issues inform clinical decision-making in Pakistan and hence these discussions should be incorporated into medical education. Further studies must be conducted on the actions that need to be taken to help students internalize the ethical issues.
Pakistan has a strong geo-strategic location in South Asia that served as a corridor for subsequent human migration events which configured its genetic variation. Besides, Indo-Pak has previous history of frequent invasions that contributed to the diversity of culture and reshaped its genetic makeup. Pakistani population is categorized in various ethnic groups major of them are Punjabi, Pathan, Baloch, Sindhi, Kashmiri, Hazara and Makrani. I have characterized mitochondrial DNA control region, Y-Chromosomal STRs and autosomal STRs on 318 random individuals from three ethnic groups; Sindhi, Kashmiri and Hazara. Mitochondrial DNA control region analysis revealed that the major proportion of Sindhi and Kashmiri maternal lineage was contributed by South Asian and Eurasian haplogroups respectively. The minor proportion was contributed by East Asian, American and African haplogroups. In Hazara population major maternal components were comprised of Eurasian and South Asian whereas minor maternal components of American and East Asian. Consequently, a series of invasions were reflected in Y-Chromosome gene pool of Pakistani population. Paternally inherited Y-Chromosome STRs analysis showed great haplotype diversity of Sindhi (0.999677), Kashmiri (0.99752) and Hazara (0.99989) populations which were illustrated through median joining network based on haplotypes frequencies. Allelic frequency distribution exhibited that locus DYS385b was more diverse and polymorphic in Kashmiri (0.8001), Sindhi (0.8373) and Hazara (0.8373) populations whereas locus DYS391 was least diverse in Kashmiri (0.4374) and locus DYS392 displayed minimum diversity value in Sindhi (0.4515) and Hazara (0.4515) population. Moreover, in this study 318 individuals from Sindhi, Kashmiri and Hazara populations were genotyped for 15 autosomal STRs. Distribution of allele frequency and other forensic efficiency parameters; for instance Power of Exclusion (PE), Matching Probability (MP) and Power of Discrimination (PD) were estimated for Sindhi, Kashmiri and Hazara populations. Locus D2S1338 exhibited maximum power of discrimination in Sindhi (0.9594), Kashmiri (0.963) and Hazara (0.967). Pairwise linkage disequilibrium was also estimated at a probability level of p<0.05 revealed that three loci D3S1358, TPOX and D8S1179 in Sindhi population were significantly deviated from Hardy-Weinberg equilibrium. On the other hand after applying the Bonferroni correction (p<0.003) only one locus TPOX remain deviated from Hardy-Weinberg equilibrium. Locus D18S51 and D19S433 in Kashmiri and Hazara population respectively displayed deviation at the probability level of p<0.005 however, no deviation was observed after Bonferroni correction (p<0.003). Accordingly, the pattern of heterogeneous admixture and genetic variation of selected Pakistani populations were further unveiled by the comparison with local and global populations through Principal Component Analysis (PCA), Multidimensional Scaling (MDS) and Phylogenetic analysis. PCA based on mitochondrial haplogroups frequency revealed the genetic closeness of all Pakistani populations to each other and also with Uzbekistan. MDS based on Y-chromosome haplotypes exhibited nearness of Kashmiri population with Greece and Serbia whereas Sindhi population indicated the genetic affinity with East Anatolia and Iran. Bipaternal phylogenetic analysis displayed that Sindhi population was in vicinity of Iraq and Kashmiri population was near to South India. Hazara population shared ancestors with Siberia and Mongol populations. Furthermore, the data generated in this comprehensive study can be used to establish lineage of Sindhi, Kashmiri and Hazara population and to develop a data base of Pakistani population for forensic purpose.
