Background: Distraction osteogenesis for craniosynostosis is associated with significant hemorrhage. Additionally, patients usually require several transfusions. Tranexamic acid (TXA) is effective for reducing blood loss and the need for transfusions during surgeries. ⋯ The duration of mechanical ventilation and the number of postoperative respiratory-related complications were significantly greater in the control group than they were in the TXA group. Conclusions: TXA infusion based on population pharmacokinetic analysis is effective in reducing blood loss and the need for transfusions during the surgical treatment of craniosynostosis. It can also prevent the increase in D-dimer levels without affecting systemic hemostasis.

Evidence-Based Medicine (EBM) is the way we are expected to deliver our healthcare in the 21st century. It has been described as the integration of information from best available evidence with the doctor's experience and the patient's point of view. ⋯ Problems related to the reliability of evidence and to the way guidelines are constructed, implemented and followed are discussed in detail. It is mandatory that the whole medical community takes responsibility and tries to reverse this apparently inexorable process so to re-establish a proper evidence-based care, where patients and their healing relation with practitioners are at the centre and where doctors are able to critically evaluate the available evidence and use it in light of their personal experience and knowledge.

Background: The study examined the difference in the expression of the receptor for activated C kinase 1 (RACK1) between anaesthesia with propofol and isoflurane in rats with myocardial ischemia-reperfusion injury (IRI). Methods: Male Sprague-Dawley rats were studied. Anaesthesia was induced with xylazine 20 µg/g by intraperitoneal injection and maintained with propofol or isoflurane. ⋯ However, the heart injury scores in the two groups did not differ significantly (3.56 ± 0.29 vs. 4.33 ± 0.23 in the propofol and isoflurane groups, respectively, p=0.33). Conclusion: There were significant differences in inflammation and apoptosis, including the expression of RACK1 and TLR4, after myocardial IRI between the propofol and isoflurane groups. However, both groups had similar heart injury scores.

Background: Due to the increased prevalence of osteoporosis and direct health care cost of osteoporosis-related fractures, there is a growing interest in identifying genetic markers associated with osteoporosis phenotypes in order to develop genetic screening strategies. We aimed to analyze the possible associations between calcaneal Quantitative ultrasound (QUS), a valuable screening tool for assessing bone status in clinical practice, and ZBTB40 (rs7524102, rs6426749), SP7 (rs2016266) and AKAP11 (rs9533090) genes. Methods: A cross-sectional study was conducted on 550 healthy individuals of Caucasian ancestry (381 females and 169 males, median age 20.46±2,69). ⋯ After applying the Bonferroni correction for multiple testing (p=0.012), only the association of rs9533090 in AKAP11 remained significant. Conclusion:AKAP11 gene (rs9533090) influences QUS trait in a population of Caucasian young adults. The rs9533090 SNP may be considered a factor affecting peak bone mass acquisition.

Renal tubule cell apoptosis plays a pivotal role in the progression of chronic renal diseases. The previous study indicates that Sirolimus is effective on unilateral ureteral obstruction (UUO)-induced renal fibrosis. However, the role of Sirolimus in renal tubular apoptosis induced by UUO has not yet been addressed. ⋯ After UUO, there was an increase in tubular and interstitial apoptosis in untreated controls as compared to Sirolimus treatment rats (P<0.05). In addition, the expression of PCNA, Bcl-2, Bax, caspase-9, and caspase-3 in obstructed kidney was characterized by immunohistochemistry and Western blot analyses demonstrating that sirolimus treatment significantly reduced PCNA, Bax, caspase-9 and cleaved caspase-3 expression compared to those observed in controls (P<0.05), whereas, Bcl-2 in the obstructed kidney were decreased in untreated controls compared to Sirolimus treatment rats subjected to the same time course of obstruction (P<0.05). We demonstrated a marked renoprotective effect of sirolimus by inhibition of UUO-induced renal tubular apoptosis in vivo.
