We determined the role of mean platelet volume (MPV) and platelet distribution width (PDW) in the prediction of placental abruption (PA) prior to caesarean section. Data obtained between January 2011 and July 2014 from patients (n = 33) with PA and healthy control subjects (n = 67) matched for age- and gestation-stage were analysed. Pre-operative and post-operative MPV and PDW were significantly different between the PA and control groups when cut-off values for MPV were set at 9.23; sensitivity at 87.8% and specificity at 46.2%; positive predictive value (PPV) at 48.3%; and negative predictive value (NPV) at 90.0%. When the cut-off value for PDW was set at 18.5, the sensitivity was 100% and specificity 71.6%, PPV 40.7% and NPV 59.3% for the prediction of PA. MPV and PDW levels were significantly higher in cases of PA. These results suggest that clinical evaluation of MPV and PDW displays reasonable sensitivity and specificity as a marker of PA, prompting the need for more research in this area of clinical study.

Background: Platelets are correlated with myeloid leukemia (ML), but to date, there have been no studies confirming the causal relationship between them.
Methods: Platelet count (PLT), mean platelet volume (MPV), plateletcrit (PCT), and platelet distribution width (PDW) data were obtained from the GWAS catalog database as exposure factors. Acute myeloid leukemia (AML) and chronic myeloid leukemia (CML) data were obtained from the FinnGen database as outcome indicators.

Percutaneous valve implantation or surgical replacement with mechanical or biological valves are standard therapies for severe valvular heart diseases. Prosthetic valve thrombosis, though rare, is a serious complication, particularly with mechanical prostheses. This study aimed to investigate the predictive value of platelet volume parameters, including mean platelet volume (MPV), platelet distribution width (PDW), and platelet-large cell ratio (P-LCR), for valvular thrombosis risk in patients undergoing valve replacement therapy.

Introduction: Colorectal cancer (CRC) staging is essential for effective treatment planning and prognosis. While platelet indices have shown promise in indicating CRC aggressiveness, a platelet index-based predictor for CRC staging has not been established in Indonesia. This study aimed to explore the relationship between platelet indices and CRC stage and to develop a predictive model and application.

The elevated risk of cardiovascular disease (CVD) associated with inflammatory rheumatic diseases has long been recognized. Patients with established rheumatoid arthritis (RA) have a higher mortality rate compared to the general population due to abnormal platelet activation. Thymidine phosphorylase (TYMP) plays a crucial role in platelet activation and thrombosis, following bridging the link between RA and CVD.

Objectives: To explore the mechanism of Granules (QJZG) for improving thrombocytopenia in a mouse model of systemic lupus erythematosus (SLE).
Methods: Twenty-four MRL/lpr lupus mice were randomized equally into 4 groups for treatment with daily gavage of saline, QJZG or prednisone (Pred) or intraperitoneal injection (twice a week) of CaMKK2 activator, with 6 C57BL/6 mice with saline gavage as the control group. After 8 weeks of treatment, the mice were examined for PLT, PCT, PDW, MPV, serum levels of TPO, IL-6, IL-10, TNF-α and IFN-γ, and calcium ion fluorescence intensity using ELISA or flow-through assay.
