Kisspeptin, a peptide hormone, plays a pivotal role in fertility and neuroendocrine regulation of hypothalamo-pituitary-gonadal axis. Increased kisspeptin and reproductive hormones are responsible for fertility in male and females. This study aimed to explore the role of kisspeptin on hypothalamo-pituitary-gonadal axis by comparing the levels of kisspeptin in fertile and infertile subjects and identifying single nucleotide polymorphisms (SNPs) of KISS1 gene in exon 2 and exon 3 of infertile male and female cohorts. A cross-sectional study was carried out on 80 males (44 infertile and 36 fertile) and 88 females (44 in each group). Significantly high levels of kisspeptin (KP), …

Background & Objective: Kidney Injury Molecule-1 (KIM-1) is a peptide whose release into circulation is specific to tubular injury. This study aimed to estimate levels of kidney injury molecule-1 in diabetic patients with and without kidney disease. And evaluate the role of KIM-1 as an early screening marker of progressive kidney injury.
Methods: This follow-up study included n=85 subjects from the diabetic clinic of Jinnah Post Graduate Medical Center (JPMC) in collaboration with Aga Khan University from November 2016 till September 2017. They were divided as: i) Group A1 (n=30) participants with diabetes for <5 years without microalbuminuria ii) Group A2 (n= 30) subjects with diabetes for 6-10 years with microalbuminuria; iii) Group B (n=25) subjects as healthy control group. All study participants were followed for 6 months and their blood glucose, urea, creatinine, electrolytes, albuminuria and serum KIM-1 were assayed.
Results: High KIM-1 at baseline was …

Objective: To compare stress markers and reproductive hormones in fertile and infertile females, and to relate the markers with age, duration and cause of infertility, and body mass index..
Methods: The case-control study was conducted at Aga Khan University Hospital, Karachi, from March 2017 to February 2018. Females aged 16-50 years regardless of ethnic background were recruited from the Australian Concept Infertility Medical Centre, Karachi, and were equally divided into infertile cases group A, and fertile controls group B. Serum follicular stimulating hormone, luteinizing hormone, estradiol, glutathione reductase and cortisol were measured using enzyme-linked innmunosorbent assay. SPSS 19 …

Background: Problem-based learning (PBL) is one of the main pedagogical approaches utilized in the undergraduate medical education (UGME) program at a private medical college in Karachi, Pakistan. Video-enhanced cases and formative assessments were introduced at the end of PBL sessions to evaluate their effectiveness in enhancing student engagement.
Methods: A mixed methods study was conducted with Year 2 medical students (n=102; divided into 11 groups) and faculty (n=11) facilitating the PBL process. Of the 10 PBL cases, five were converted to video-enhanced cases and five were kept as paper-based, “traditional” cases. “Micro” videos were used to introduce clinical scenarios, augmented …
