Commercial blood cell separation systems versus tube centrifugation methods for the preparation of platelet-rich plasma: a preliminary cross-sectional study.
Clinical studies claim that platelet-rich plasma (PRP) accelerates tissue healing due to its high concentration of growth factors and that the combination with leukocytes improves the antimicrobial effect of the concentrate. Most of these studies obtained PRP using different separation systems, and few analyzed the content of the PRP used for treatment. This study characterized the composition of PRP and white blood cells (WBC) from a single donor produced by three commercially available PRP separation systems and two anticoagulated general analytical tubes. ⋯ The Easy PRP Kit concentrates WBC-rich PRP, resulting in increased WBC concentrations, compared with low WBC-low PRP of GloPRP and general tube methods for EDTA and citrate analysis and the even lower concentration of PRP from the Wego Kit, with the absence of leukocytes.

Relationship between body mass index and waist-to-height ratio in childhood.
To evaluate whether there is an association between the body mass index z-score and waist-to-height ratio of children and adolescents. ⋯ There was a significant correlation between body mass index and waist-to-height ratio. This association was higher in adolescents. The waist-to-height ratio is easy to apply and may be useful as a predictor of cardiometabolic risk.

Motor development of infants (6-12 months) with low birth weight.
The aim of this study was to describe the motor development (MD) and growth of infants born with low birth weight (LBW) versus adequate birth weight (ABW) by using the Alberta Infant Motor Scale (AIMS). ⋯ A frequency of 45% of suspected or abnormal behavior was observed in the evaluated infants, with a higher frequency of occurrence in those aged 9-12 months (54.6%).

A comparison of computerized tomography findings of COVID-19 infection by gender and age groups.
To compare the computed tomography (CT) imaging findings of coronavirus disease 2019 (COVID-19) by gender and age groups. ⋯ The chest CT findings of COVID-19 show significant changes according to age and gender. The findings that are more common in elderly and male patients should be carefully evaluated in terms of the prognosis of the disease.
