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.

Examination of clinical data and semen analysis results of patients undergoing orchiectomy for testicular tumor.
Testicular tumor constitutes 1% of male neoplasms. Infertility can be determined in patients with testicular tumors before orchiectomy due to the deterioration of spermatogenesis. The aim of this study was to show the clinical, radiological, and pathological characteristics and spermiogram results of patients with testicular tumor and their relationship with each other. ⋯ Spermatogenesis adversely affected before the treatment due to local and systemic effects of testicular cancer. Fertility expectations can be increased in the subsequent years by semen analysis and referral to cryopreservation.

Some inflammatory markers and chest computerized tomography in patients with severe acute respiratory syndrome coronavirus infection.
We retrospectively assessed whether there was a relationship between lung complications and some easily accessible markers to predict the presence of pulmonary consolidation in patients with coronavirus disease 2019 (COVID-19). ⋯ Increased age and C-reactive protein (CRP) may suggest pulmonary infiltration on chest CT in patients with COVID-19.

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.
