Preoperative platelet count and volume could not help predict PONV in women undergoing breast cancer surgery: A prospective cohort study

The preoperative platelet to albumin ratio predicts the prognosis of hepatocellular carcinoma patients without portal hypertension after liver resection

There is little information concerning the predictive ability of the preoperative platelet to albumin ratio (PAR) in hepatocellular carcinoma (HCC) patients after liver resection. In the current study, we aimed to assess the prognostic power of the PAR in HCC patients without portal hypertension (PH) following liver resection.Approximately 628 patients were included in this study. A receiver operating characteristic (ROC) curve analysis was performed to evaluate the predictive value of the PAR for both recurrence-free survival (RFS) and overall survival (OS). Univariate and multivariate analyses were used to identify the independent risk factors for both RFS and OS.During the follow-up period, 361 patients experienced recurrence, and 217 patients died. ROC curve analysis suggested that the best cut-off value of the PAR for RFS was greater than 4.8. The multivariate analysis revealed that microvascular invasion (MVI), tumor size >5 cm, high aspartate aminotransferase-to-platelet count ratio index (APRI) and high PAR were four independent risk factors for both RFS and OS. Patients with a low PAR had significantly better RFS and OS than those with a high PAR.The PAR may be a useful marker to predict the prognosis of HCC patients after liver resection. HCC patients with a high preoperative PAR had a higher recurrent risk and lower long-term survival rate than those with a low preoperative PAR.

The role of platelet count, mean platelet volume, and the mean platelet volume/platelet count ratio in predicting postoperative vomiting in children after deep sedation

Objectives:

To determine the role of hemogram parameters such as platelet count (PLT), mean platelet volume (MPV), and the MPV/PLT ratio in predicting the risk of postoperative vomiting (POV) in children after tooth extraction under deep sedation.

Methods:

A total of 100 American Society of Anesthesiology Classification I and II pediatric patients who underwent tooth extraction procedures under a standard anesthetic method were included in the study between 2012 and 2014. The study took place at the Faculty of Dentistry, Department of Oral and Maxillofacial Surgery, Erciyes University, Erciyes, Turkey Fifty patients without POV (group 1) and 50 patients with POV (group 2) were retrospectively selected randomly from the records of 885 consecutive patients. Age, gender, duration of the operation, and preoperative hemogram findings were recorded.

Results:

There was a statistically significant difference between the 2 groups in terms of MPV (p<0.001), PLT (p=0.006), and MPV/PLT (p<0.001) ratio. Mean platelet volume and MPV/PLT ratio were higher in group 2, whereas PLT was higher in group 1.

Conclusion:

The PLT count, MPV, and MPV/PLT ratio may be used to predict POV in children.
