There is no definite recommendation for testing platelet aggregation (PA) in acute coronary syndromes (ACS) due to inconclusive evidence on the usefulness of platelet function tests to guide therapy and improve clinical outcomes. The evaluation of PA with multiple electrode impedance platelet aggregometr...

ABSTRACT Objective: To compare the neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios as possible parameters of systemic inflammation in hyperglycemic and normoglycemic subjects. Methods: A retrospective, cross-sectional study of data collected from patients tested for fasting blood glucose, gl...

OBJECTIVES: Thirty to sixty percent of prepared blood products are not transfused. Blood reserves for surgeries lead to many unused blood products, which increases hospital costs. The aim of this study is to identify the request and use profiles of blood products for elective surgeries in different surgi...
Abstract Purpose: To investigate the prognostic value of 17 platelet-based prognostic scores in patients with malignant hepatic tumors after TACE therapy. Methods: In total, 92 patients were divided into death group and survival group according to long-term follow-up results. The AUC was calculated to ...

Objective: to determine the platelet recovery and yield of the PRGF-U1 protocol in a peruvian population. methods: an observational, descriptive and cross-sectional study was conducted with a simple random probability sample of 32 patients who attended the laboratorio Scalab in Trujillo, Peru. a blood sa...
We report a 51-year-old female who had a first episode of thrombocytopenia at 23 years of age during a pregnancy. At the age of fifty, a hysterectomy was indicated due to a metrorrhagia: a platelet count of 21,000/ul was detected. She was treated with eltrombopag with a good response. The family history ...
