Background: Studies have supported the correlation between mean platelet volume and COPD. However, there are limited data on the relationship between COPD exacerbation and mean platelet volume. We aimed to evaluate the mean platelet volume trend in patients with COPD exacerbation.
Methods: A total of 81 subjects, 62 men and 19 women, who were admitted to the hospital because of exacerbation of COPD during 9 months, were enrolled in this prospective observational study. The levels of mean platelet volume, C-reactive protein, complete blood count, and percent-of-predicted FEV1 were measured in subjects at admission (exacerbation period) and after 3 months (stable period). Thirty-seven age- and sex-matched healthy individuals constituted the control group.
Results: Subjects in the exacerbation period had significantly higher levels of C-reactive protein (P = .001), white blood cell count (P = .01), and percentage of neutrophils (P = .01) and lower percent-of-predicted FEV1 than in the stable period (P = .02). Mean platelet volume levels were significantly decreased in the exacerbation period (P = .001). Considering a cut-off point of mean platelet volume levels <8.2 fL for indicating COPD exacerbation showed a sensitivity of 80% and a specificity of 76%. Also, mean platelet volume levels correlated significantly with increase of C-reactive protein level, white blood cell count, and neutrophil percentage in the exacerbation period (P = .01, P = .01, and P = .02, respectively).
Conclusions: Mean platelet volume may be an inflammatory marker in exacerbation of COPD, and the measurement of mean platelet volume values may be useful for identifying patients who are at increased risk for exacerbations of illness.

Background: Rapid, reproducible, and noninvasive diagnostic methods like Ultrasonography (US) and plethysmographic measurements such as the perfusion index (PI) and pleth variablity index (PVI) have great potential value for emergency trauma cases in which blood loss needs to be recognized quickly and accurately.
Objectives: We planned this study to evaluate the utility of US, PI, and PVI in detecting early-stage hemorrhage and mimicking volume replacement using a platelet apheresis model.
Methods: This prospective, observational study included 46 healthy platelet apheresis volunteers who met inclusion criteria.

Background: Spontaneous intracerebral hemorrhage (SICH) is the second most common cause of cerebrovascular disease after ischemic stroke, with high mortality and disability rates, imposing a significant economic burden on families and society. This retrospective study aimed to develop and evaluate an interpretable machine learning model to predict functional outcomes 3 months after SICH.
Methods: A retrospective analysis was conducted on clinical data from 380 patients with SICH who were hospitalized at three different centers between June 2020 and June 2023.

Introduction: The Reveos automated blood processing system is the only system developed till date, which can separate whole blood into components on complete automation. Their proprietary LR and NLR blood collection sets have their own advantages and disadvantages. Using LR sets, leukodepleted components can be prepared but individual platelet units cannot be prepared.
