Objective: Premature adrenarche (PA) has been associated with an increase in adrenal androgens, and the hyperandrogenic hormonal environment is known to lead to increased platelet (PLT) aggregation. Here, we evaluated the effects of PA on PLT aggregation in PLT-rich plasma samples from female patients.
Methods: The study included 40 female patients diagnosed with PA between February, 2014 and June, 2018 and 30 healthy female individuals as a control group. Adenosine diphosphate (ADP) and collagen-induced PLT aggregation were studied via the photometric aggregometry method.
Results: There were no significant differences in the PLT count or volume values between those participants with PA and the control group. Additionally, the ADP-induced maximum aggregation time, value, and slope values did not significantly differ between the patient and control groups (p>0.05). However, the collagen-induced maximum aggregation time, value, and slope values were significantly higher in the studygroup (p<0.001).
Conclusion: Increased collagen-induced PLT aggregation was detected in female patients with PA. As PA is associated with a higher risk of cardiovascular events later in life, close follow-up of PA in this respect may be beneficial.

Patients with transfusion-dependent β-thalassemia (TDT) with iron overload have been linked to hypercoagulability and increased platelet (PLT) activation that causes thrombosis. Green tea extract (GTE) rich in epigallocatechin-3-gallate (EGCG) exerts iron-chelating and antithrombotic properties. The study aimed to assess the effects of GTE treatment on plasma coagulation state and PLT function in vitro and in patients with TDT.

Background: Pathogen reduction (PR) may be used as an alternative to gamma or x-ray irradiation (I) to prevent transfusion associated graft versus host disease (TA-GVHD) if the pathogen reduction technology has been shown to inactivate residual lymphocytes. However, as I is considered the gold standard for reducing the risk of TA-GVHD, some centers continue to perform I in addition to PR. This study investigated the effect of concurrent pathogen reduction and irradiation (PR/I) on the biochemical characteristics of apheresis platelets at day 1, 5, and 7 of storage at room temperature.

Objective: Cardiovascular diseases (CVDs) are the leading cause of death worldwide, with atherosclerosis serving as a primary factor in their development. Platelets, leukocytes, and their interactions play a crucial role in initiating and amplifying atherosclerosis. This study aims to evaluate the levels of platelet-monocyte aggregates (PMA) and specific integrins involved in leukocyte recruitment, including macrophage-1 antigen (Mac-1) and lymphocyte functionassociated antigen-1 (Lfa-1), in patients with acute coronary syndrome (ACS).

Introduction: Platelets (PLT) and host systemic inflammatory response (SIR) are known to be effective in the aggregation of cancer cells and the formation of metastasis. There are studies pointing out to the prognostic efficacy of lymphocyte-monocyte ratio (LMR) showing SIR activation and mean platelet volume (MPV) values indicating platelet activation in various cancer types. We predict that easy-to-access hemogram parameters such as MPV, MPV/PLT, and LMR can be guiding in the clinical follow-up period of patients with epidermal growth factor receptor (EGFR) positive mutation and who received EGFR, tyrosine kinase inhibitor (TKI) in the first-line treatment in predicting the progression of the disease, predicting the survival time of the patients, and evaluating the response to treatment.

Objective: The investigation purpose was to examine the correlation between the aggregate index of systemic inflammation (AISI) and rheumatoid arthritis (RA) by utilizing the NHANES database from the years 1999 to 2018.
Methods: The NHANES database was utilized to extract data spanning from 1999 to 2018. AISI, comprising neutrophils (NEU), monocytes (MONO), platelets (PLT), and lymphocytes (LYM), was computed based on counts.
