While thrombocytopenia's link to mortality is known, the prognostic impact of longitudinal trajectories platelet indices in combination with analysis mediating role remains unexplored. This first study that addresses this significant gap by investigating association between seven trajectory subphenotypes and ICU mortality, considering influence.

Immature platelet fraction (IPF) estimation is a non-invasive and sensitive test that available on recently introduced Sysmex XN-series of automated haematology analysers. It direct cellular indicator thrombopoiesis. The aim this study was to establish reference intervals for IPF, both absolute (A-IPF) percentage (%-IPF) measurements.A total 2366 samples met the inclusion criteria were assayed full blood count XN-10 non-parametric percentile method used calculating intervals.After outliers...

This study aimed to define the sex-divided reference intervals for platelet indices (mean volume (MPV), distribution width (PDW), large cell ratio (P-LCR) and plateletcrit (PCT)) on Sysmex XN-10.A total of 2376 samples were assayed full blood count XN-10 haematology analyzer. After removing outliers, calculated using mean±2SD. The P value 0.05 was adopted denote statistical significance.There a significance (α=0.05) between MPV (p=0.007), P-LCR (p=0.015) PCT (p<0.001), thus separate these...

Introduction The management of non-alcoholic steatohepatitis (NASH) is an unmet clinical need. Misoprostol, a structural analogue naturally occurring prostaglandin E1, has been reported to decrease proinflammatory cytokine production and may have potential role in treating NASH. We aimed evaluate the efficacy safety misoprostol patients with Methods In this phase 2, double-blind, randomised, placebo-controlled trial, NASH were randomly assigned 1:1 ratio receive 200 µg or placebo thrice...

Background The Immature Platelet Fraction (IPF) is an indicator of thrombopoiesis which a useful parameter in thrombocytopenia. It demonstrates compensatory mechanisms production platelets, but currently not implemented routine clinical practice. aim this study was to establish the reproducibility and stability IPF, for both percentage (%-IPF) absolute (A-IPF) measurements.Material/methods: A total 71 samples, 45 26 analysis, were assayed full blood count using Sysmex XN-10 analyser at room...

Background: Insulin resistance, a major pathogenic factor in Gestational Diabetes Mellitus (GDM), has an inverse correlation with adiponectin; therefore, the role of adiponectin pathogenesis GDM been suggested. The study aimed to determine mean levels and frequency hypoadiponectinemia patients GDM. Methods: was carried out at Dr. Ziauddin University Hospital, Karachi from June 2016 December 2017. A total 99 women age group 15-45 years diagnosed on Oral Glucose Tolerance Test (OGTT) 24-28...
