Kidney transplantation has been considered as the most effective therapy for patients with end-stage renal disease. However, less attention was attached to infertility. The present meta-analysis was conducted to compare the semen quality between patients with dialysis and patients after kidney transplantation. An extensive search in MEDLINE, PubMed and Web of Science was conducted from inception to March 2021. The data extracted for meta-analysis included sample size and characteristics, main reported outcomes like semen quality and hormone levels. For the semen quality and hormone levels, the standardized mean difference (SMD) and 95% confidential interval (CI) were calculated to evaluate the effect size. Finally, 5 studies were included in meta-analysis. Kidney transplantation could improve the sperm density of patients undergoing dialysis (SMD 1.58 [0.02, 3.15]). Additionally, the sperm motility was also improved after the kidney transplantation (SMD 3.26 [0.73, 5.79]). The sperm density of kidney transplantation patients was lower than that in healthy subjects (SMD -0.75 [-1.42, -0.07]), same as the sperm motility (SMD -0.50 [-0.80, -0.20]). Our meta-analysis suggests kidney transplantation could improve semen quality of patients with ESRD, including sperm density and sperm motility. Of note, semen quality of renal transplantation recipient still is inferior to healthy subjects.Gamma hydroxybutyric acid (GHB) has been approved clinically to treat excessive daytime sleepiness and cataplexy in patients with narcolepsy, alcohol and opioid withdrawal, and as an anesthetic. The use of GHB clinically is limited due to its high abuse potential. The absorption, clearance and tissue uptake of GHB is mediated by proton-dependent and sodium-coupled monocarboxylate transporters (MCTs and SMCTs) and inhibition of these transporters may result in a change in GHB pharmacokinetics and pharmacodynamics. Previous studies have reported that non-steroidal anti-inflammatory drugs (NSAIDs) may inhibit these monocarboxylate transporters. Therefore, the purpose of this work was to analyze the interaction between GHB (at a dose of 600 mg/kg i. v.) and the NSAID, diclofenac, by examining the effects of this drug on the in vivo pharmacokinetics and pharmacodynamics in rat studies. The pharmacodynamic effect evaluated was respiratory depression, a measure of toxicity observed by GHB at this dose. There was an improvement in the respiratory rate with diclofenac administration suggesting an effect of diclofenac on GHB toxicity. In vitro studies with rat blood brain endothelial cells (RBE4) that express MCT1 indicated that diclofenac can inhibit GHB transport with an IC50 of 10.6 μM at pH 7.4. In vivo studies found a decrease in brain GHB concentrations and a decrease in the brain-to-plasma concentration ratio following diclofenac treatment. With this study we can conclude that diclofenac and potentially other NSAIDs can inhibit the transport of GHB into the brain, therefore decreasing GHB's pharmacodynamic effects and toxicity.In a health crisis of the calibre of the COVID-19 pandemic, the development of effective and safe vaccines is considered the most powerful measure to save lives and minimise the tremendous negative impact on health, social systems and global economics. Vaccines must be evaluated and approved by the appropriate regulatory and/or health authorities. To date, the worldwide regulatory landscape for vaccines is very broad. Bringing COVID-19 vaccines to the market, the authorities followed at least 51 different pathways, offering various types of accelerated vaccine approval. 1 China, Russia and the United Arab Emirates initiated the vaccine administration before the conclusion of clinical trials. This patchwork of approval processes has revived a long-standing question, how to better facilitate harmonization in vaccine regulation and whether a harmonized approval process would make the vaccine development procedures more effective, quicker, broadly accessible and administered by the whole world and even less expensive. In this issue, experts from the Paul-Ehrlich Institute, the regulatory institution for vaccine development in Germany, describe the regulatory procedures, concepts and requirements that are applied to guide and promote the accelerated development and licensure of safe and efficacious COVID-19 vaccines in Europe.2.Retraction "Expression of nestin in embryonic tissues and its effects on clinicopathological characteristics of patients with placenta previa," by Yan-Yan Qiao, Ping Chu, J Cell Biochem. 2018; 2061-2072 The above article, published online on 18 August 2017 in Wiley Online Library (https//onlinelibrary.wiley.com/doi/10.1002/jcb.26368) has been retracted by agreement between the the journal's Editor in Chief, Prof. Dr. Christian Behl, and Wiley Periodicals LLC.

To characterize the clinical features associated with sinonasal complaints after maxillectomy with free flap reconstruction as well as propose a screening and treatment algorithm.

Retrospective review of patients who underwent maxillectomy and free flap reconstruction at a tertiary care center.

Fifty-eight patients were included, 25 (43.1%) of them had documented sinonasal complaints postoperatively. 2-Aminoethyl molecular weight Eleven patients subsequently underwent revision surgery for sinonasal complaints. Among the 25 patients with sinonasal complaints, 22 patients (88.0%) had nasal crusting, 17 (68.0%) had nasal obstruction, 12 (48.0%) had rhinorrhea, 9 (36.0%) had facial pain or pressure, and 7 (28.0%) had foul odor. Twenty-two patients (88.0%) had multiple sinonasal complaints. There was a higher incidence of both sinonasal complaints and surgical intervention in patients who underwent adjuvant radiation, but this was not statistically significant (47.7% vs 28.6%, P= .235; 29.4% vs 7.1%, P= .265).

Sinonasal complaints are common following free flap reconstruction for a maxillectomy defect and should be screened for at postoperative visits, with early referral to a rhinologist for consideration of endoscopic sinus surgery.
