Frequency of Premenstrual Dysphoric Disorder (PMDD) and Comparison of Quality of Life between Female Medical Students with and without Premenstrual Dysphoric Disorder.

OBJECTIVE: To determine the frequency of Premenstrual Dysphoric Disorder (PMDD) in female medical students, and to compare the quality of life between those with and without PMDD. STUDY DESIGN: Descriptive Study. Place and Duration of the Study: Fatima Jinnah Medical University, Lahore, from November 2019 to April 2020. METHODOLOGY: The study included 635 female medical students from the third year to the final year of MBBS. Quality of life was measured by using the World Health Organization Quality of Life Brief (WHOQOL-BREF) Scale and PMDD was diagnosed as per DSM-V Diagnostic criteria. Data were entered and analysed by IBM SPSS version 23.0. Scores of 4 domains of the WHOQOL-BREF scale were compared between the female medical students with and without PMDD. A p-value of ≤0.05 was considered statistically significant. RESULTS: Significant proportion i.e., 12.1% (77) out of 635 female medical students had PMDD. There was a significant difference in the physical and psychological domains scores of the WHOQOL-BREF scale between healthy students and students with PMDD (p-value <0.001). CONCLUSION: The physical and Psychological aspects of quality of life are significantly lower in female medical students with PMDD. KEY WORDS: WHOQOL-BREF, Premenstrual dysphoric disorder, Female medical students.

Synthesis and receptor binding in trans-CD ring-fused A-CD estrogens: comparison with the cis-fused isomers.

Ligands which selectively activate only one of the estrogen receptors, ERα or ERß, are current pharmaceutical targets. Previously, we have reported on substituted cis A-CD ligands in which the B-ring of the steroidal structure has been removed and cis refers the stereochemistry of the CD ring junction as compared to trans in estradiol. These compounds often showed good potency and selectivity for ERß. Here we report the synthesis and binding affinities for a similar series of trans A-CD ligands, and compare them to the cis-series. Counterintuitively, trans A-CD ligands, which are structurally more closely related to the natural ligand estradiol, show weaker binding and less ß-selectivity than their cis-counterparts.
