BACKGROUND: If immune responses to vaccination differ between males and females, sex-specific vaccination schedules may be indicated. We systematically reanalysed childhood vaccination studies conducted in The Netherlands for sex-differences in IgG-responses. To assess the impact of potential sex-differences in IgG-responses, we explored sex-differences in vaccine failure/effectiveness and reactogenicity. METHODS: Six studies with IgG-measurements for 1577 children following infant pneumococcal (PCV7/PCV10/PCV13) and/or DTaP-IPV-Hib(-HepB) vaccinations, or the pre-school DTaP-IPV booster were included...

Pilonidal disease (PD) is a chronic situation which may cause pain, discomfort, inflammation, discharges, and inability to do daily routines. Among two main methods of surgery, open healing is preferred by surgeons since it associates with lower risk of recurrence; however, it could complicate the wound condition by delaying the healing process. For this meta-analysis, a search in Medline, Embase, and Scopus was performed in June 2017 with no restrictions placed on the publication date or languages. Then, time to healing was considered as the effect size and all the data from trials were extracted...

BACKGROUND: Androgenetic alopecia (AGA), the most common cause of hair loss in both sexes, accounts for 95% of all cases of hair loss. Although the literature has suggested that both nonactivated (n-PRP) and activated autologous (a-PRP) PRP can be used to treat AGA, we did not find any study investigating the use of homologous PRP (h-PRP) for this purpose. Also, to the best of our knowledge, there are no studies comparing the efficacy of h-PRP, a-PRP, or n-PRP on AGA therapy. OBJECTIVES: The aim of this study was to compare the increase in hair density, average number of platelets, complications, preparation, and duration of application in the treatment of AGA using a-PRP, n-PRP, and h-PRP...

Concentrated leukocytes in leukocyte and platelet‑rich plasma (L‑PRP) may deliver increased levels of pro‑inflammatory cytokines to activate the nuclear factor (NF)‑κB signaling pathway, to counter or overwhelm the beneficial effects of growth factors on cartilage regeneration. However, to date, no relevant studies have substantiated this. In the present study, L‑PRP and pure platelet‑rich plasma (P‑PRP) were prepared, and leukocytes, platelets, pro‑inflammatory cytokines and growth factor concentrations were quantified; they were then used to treat human articular chondrocytes (HACs)...
