Scarce data are available regarding the technique and outcomes for patients with RCC and Mayo III caval thrombi. To report surgical and oncological outcomes of RCC patients with Mayo III thrombi treated with radical nephrectomy and thrombectomy after liver mobilization (LM) and Pringle Manoeuvre (PM).
Retrospective analysis of surgical technique, outcomes and cancer control in 19 patients undergoing LM and PM in a single tertiary care institution.
Overall, 78% of the patients had performance status ECOG 1 and 58% had a comorbidity index >2. Median surgical time was 305 minutes (IQR 264-440). Intraoperative complications were reported for 39% of patients and postoperative ones for 58% (only Grade 1 and 2). Intensive Care Unit support was necessary in 16% of the cases. Median length of hospital stay was 9 days (IQR 7-11). Thirty- and 90-day mortality were 5% and 15%. Twoyear overall survival and cancer-specific survival were 60% and 62%, respectively.
We reported surgical techniques, intra and perioperative complications and follow-up in the largest cohort of RCC patients requiring LM and PM.

To compare the risk of cardiovascular disease (CVD) following gonadotropin-releasing hormone (GnRH) agonist and GnRH antagonist therapy for patient with prostate cancer (PCa).
We searched PubMed, Web of science, Opengery, Cochrane library databases and international congress reports for studies published before December 2019. This meta-analysis was conducted using Stata version 12.0. Relative ratios (RRs) and their credible intervals (CI) were applied for the cardiovascular safety evaluation of androgen-deprivation therapy (ADT) medical interventions, including GnRH agonist and GnRH antagonist therapy. In addition, fixed-effect or random-effect models were applied in the statistical analyses according to the heterogeneity.
Six articles including 32,997 participants were analyzed with a random effects model. The results of meta-analysis showed that compared with GnRH agonist, the incidents of CVD was equal to GnRH antagonist therapy for patient with PCa (RR 0.98, 95% CI 0.94-1.02). When considering, under sub-group analysis with randomized controlled trials (RCTs) or controlled clinical trials (CCTs), no statistical differences in risk of CVD were found in two sub-group analyses. No evidence of publication bias was found in our meta-analysis by a funnel plot (Pr> | z |=0.26).
This meta-analysis indicates that compared treatment with GnRH antagonist, risks of CVD in PCa patients was the same as GnRH agonist. c-RET inhibitor Further RCTs are strongly required to provide more definitive evidence.

Bacteria-derived outer membrane vesicles (OMVs) are commonly associated with various biological activities and functions. Helicobacter pylori-derived OMVs are thought to contribute to pathogenesis. This study aimed to investigate the effects of H. pylori-derived OMVs.
H. pylori strains were isolated from patients with gastritis, gastric ulcer, or gastric cancer using endoscopic biopsy. The U-937, AGS, and MKN-45 cell lines were exposed to H. pylori and H. pylori-derived OMVs. The expression of interleukin 8 (IL-8) messenger RNA (mRNA) was assessed using reverse transcription-polymerase chain reaction (RT-PCR) and real-time RT-PCR, and IL-8 secretion was analyzed using enzyme-linked immunosorbent assay. Nuclear factor kappa B (NF-κB) activation was evaluated by Western blotting.
H. pylori and H. pylori-derived OMVs induced the expression of IL-8 mRNA and protein. Importantly, the bacteria induced higher IL-8 mRNA and protein expression than the OMVs. IL-8 expression was induced to different levels in response to H. pylori-derived OMVs from hosts with different gastric diseases. Western blotting revealed the increased phosphorylation and reduced degradation of inhibitor of NF-κB alpha in cells exposed to OMVs.
H. pylori-derived OMVs may aid the development of various gastric diseases by inducing IL-8 production and NF-κB activation.

First we would like to comment on the role of frailty in assessment of burns. The elderly population is of special interest in all fields of clinical medicine, owing to the ageing of the world population [1]. The definition of frailty is relatively concise. It is defined as a state of depletion of the homeostatic reserve due to changes accumulated during lifetime. In consequence, resolution of stressor sequelae is impaired [2]. Although the definition is straightforward, the methods of its application and quantification of frailty are not unequivocally accepted [3]. Ward and Romanowski in their papers used the Clinical Frailty Scale [4]. Other developed scales, to mention only a few, are the general Korean Frailty Index for Primary Care [5], the Modified Frailty Index 5 (mFI-5) [6], the more specialized Emergency General Surgery Frailty Index [7], and the Burn Frailty Index [8]. Some of them were evaluated in surgery patients, and the Burn Frailty Index was developed by Maxwell specifically to be used in burn patients [8]. A study comparing the usefulness of various frailty scales in a burn ward would be a welcome addition to the discussion about burn outcomes. We would also like to address one more aspect of frailty. Generally, the term is connected with the elderly population, i.e. more than 65 years old. This is based on the fact that one's frailty is a sum of deficits accumulated over the whole lifetime [9]. Yet even in younger age groups various tools used to assess frailty show a relatively high percentage of frail people [10, 11]. Research including patients undergoing orthopaedic surgery has proven that frailty assessment is a viable choice to predict complications even in younger groups [12]. Therefore we assume that frailty indexes will gradually become tools used also in younger groups of patients.
