Combined hormonal contraceptives possess an inherent risk of thrombus-related events. The purpose of this study is to elucidate alterations in the coagulation profile among young women using combined oral contraceptive (COC) or combined vaginal contraceptive (CVC) compared to a normal, healthy, female control group using the Sonoclot coagulation analyzer. We enrolled 159 participants (64 control individuals, 51 COC users, and 44 CVC users). Each participant completed a survey of medical history, family medical history, and lifestyle choices. Citrated venous whole blood was collected and analyzed using the Sonoclot coagulation analyzer. After adjusting for age, race, alcohol consumption, sleeping habits, and family history of cardiovascular disease, and stroke, we observed COC and CVC users had mostly similar coagulation profiles except when compared to the control, and COC and CVC users had an elevated glass bead peak signal while COC users had a shorter peak time.

Parkinson's disease (PD) is the second-most prevalent neurodegenerative disease worldwide, which worsens with advancing age. It is a common movement disorder and is often associated with several vascular diseases with decreased stroke frequency. Circulating platelets substantially regulate vascular complications, including stroke, and share striking similarities with PD neurons.

Platelets are essential component of circulation that plays a major role in hemostasis and thrombosis. During activation and its demise, platelets release platelet-derived microvesicles, with lysophosphatidylcholine (LPC) being a prominent component in their lipid composition. LPC, an oxidized low-density lipoprotein, is involved in cellular metabolism, but its higher level is implicated in pathologies like atherosclerosis, diabetes, and inflammatory disorders.

Background: To find a new bedside method to monitor the anticoagulation effects of low-molecular-weight heparins (LMWHs) in patients with a high risk of venous thromboembolism (VTE).
Research Design And Methods: A total of 32 hospitalized patients (aged ≥60 years) who were at high risk of VTE were assigned to receive subcutaneous LMWH for 5 to 14 days. Plasma anti-factor Xa (anti-Xa) activity was conducted by a chromogenic method, and the glass bead-activated whole blood clotting time (gb-ACT) value was obtained by a Sonoclot Analyzer.

Maternal age has significantly increased among Chinese women, thereby posing risk of pregnancy-related complications. Preeclampsia is a leading cause of maternal and perinatal morbidity and mortality, and coagulation analysis in conjunction with clinical signs and symptoms are generally used for its diagnosis with limited efficacy. Sonoclot coagulation analyzer is effective in assessing coagulation function used during cerebral surgery and cardiovascular surgery.

Article Synopsis
- The study assesses the accuracy of Sonoclot analysis as a platelet function (PF) parameter for transfusions during cardiovascular surgery, compared to thromboelastography (TEG6s).
- Forty-two patients were randomly assigned to either the Sonoclot only group or the combined Sonoclot and TEG6s group, focusing on intraoperative platelet concentrate (PC) needs.
- Results showed no significant difference in transfusion volumes between the two methods, with Sonoclot demonstrating a moderate correlation with platelet count, while TEG6s showed a stronger correlation.
