Evaluating the Role of Platelet Indices, with a Focus on Immature Platelet Fraction (IPF), in Differentiating Hyper-Destructive and Hypo-Productive Thrombocytopenia: A Study from Ludhiana, Punjab, India
Abstract: Background: Thrombocytopenia, characterized by a reduction in platelet count, is commonly observed in clinical settings. Its etiology can be broadly classified into hyper-destructive thrombocytopenia, where platelets are destroyed at an accelerated rate, and hypo-productive thrombocytopenia, where platelet production is impaired. Differentiating between these two causes is essential for effective management. The Immature Platelet Fraction (IPF) has emerged as a promising non-invasive diagnostic tool to distinguish these causes. Objectives: The primary …

Successful Treatment of Clinical Ketosis in Dairy Cattle
Abstract: Ketosis is a post-parturient metabolic disease encountered in high yielders due to imbalance in production and feeding leading to gluconeogenesis along with formation of abnormally high levels of ketone bodies. The disorder is particularly seen within the first few weeks after calving. It arises due to a negative energy balance when energy demands for milk production exceed dietary energy intake, leading to excessive mobilization of body fat reserves and resulting …
