Minimally invasive percutaneous nephrolithotomy (PCNL) was introduced to decrease the morbidity of the standard PCNL (sPCNL). Thereafter, many modifications and techniques have been presented with the introduction of different miniaturized PCNL (mPCNL) techniques, such as micro-PCNL and ultra-mini-PCNL (UMP). As of present, none of the techniques has displaced the sPCNL. Nonetheless, mini-PCNL has continuously widening indications and has been proposed to have significant advantages over sPCNL. In the current review, each technique is presented while discussing the advantages and disadvantages of each approach. A comprehensive review of the current literature has been performed. Articles related to the topic were retrieved and critically analyzed. Less peri-operative bleeding and shorter hospital stay were the most important advantages advocated for mini-PCNL. Although the performance of mini-PCNL is safe, the utilization of micro-PCNL and UMP should be done with caution.Objective There is an increasing trend to incorporate Simulator-based training in urology residency programs. The study was designed to determine the construct validity of UroSim® for that we compared the performance of transurethral resection of bladder tumor (TURBT) between experts and novices. Material and methods We conducted a cross sectional study at a university hospital to determine the construct validity of UroSim® for TURBT. We compared the outcome measures between experts (urology consultants) and novices (residents) to determine relationship between clinical experience and performance on simulator. Primary outcome measure was resection time and secondary outcome measures were safety, bleeding, and visualization during TURBT on UroSim. We requested participant to resect three tumors to assess the test content of the simulator. Comparison of continuous variables such as resection time, resection, bleeding control, and visualization and blood loss using student t test. selleck chemicals Comparison of categorical variable, i.e. perforation of bladder, using Fischer exact test. Results We included 30 experts and 30 novices. There was a statistically significant difference in the mean resection time between the groups (196±67.4 sec versus 374.6±179.7 sec; p=0.01), suggesting a positive relationship between clinical experience and performance on simulator. Additionally, safety parameters, namely, bleeding control, inadvertent cuts into bladder wall, ureteric orifices, and bladder perforations varied between the two groups. Conclusion We observed significant differences of parameters in performance between experts and novices. Simulator is a useful tool for teaching TURBT as it demonstrates good construct validity and recommended in urology training for teaching psychomotor skills.Objective Augmentation cystoplasty is a treatment option for neurogenic lower urinary tract dysfunction as well as severe, refractory, complicated idiopathic overactive bladder. In some patients, symptoms may persist or recur postoperatively, and there is little guidance on management in this setting. In this study, we reviewed the use of intravesical onabotulinum toxin type A (BTX-A) in patients who had undergone augmentation cystoplasty. Material and methods Retrospective chart review was performed at two institutions, identifying patients who underwent augmentation cystoplasty and were subsequently treated with intravesical BTX-A. Demographics, and preoperative and postoperative findings were collected. Results In total, 21 (16 female, 5 male) patients (mean age 37.2 years) with previous augmentation cystoplasty were identified. In 17 patients with urodynamic data, mean maximum cystometric capacity was 312 mL, and decreased compliance and detrusor overactivity were noted in 53% and 48% patients, respectively. Combined intradetrusor/intra-augment injections were performed in 11 patients, and the remaining 10 patients received detrusor-only injections. A total of 18 patients (86%) reported subjective improvement with no significant difference associated with site of injection (p=0.59). A total of 17 patients (77%) underwent repeat injections; on average, patients underwent 3.3 injections with interval of 8.8 months between injections. Conclusion BTX-A injection was shown to subjectively improve storage symptoms and continence after augmentation cystoplasty in the majority of patients. In this cohort, patients had good subjective response regardless of site of injection, and most patients benefited from repeat injections. Prospective studies are needed to better evaluate the efficacy and ideal sites of BTX-A injection in the setting of refractory voiding dysfunction following augmentation cystoplasty.Background There are around 40,000 new cases of malignant pleural effusion in the UK each year. Insertion of talc slurry via a chest tube is the current standard treatment in the UK. However, some centres prefer local anaesthetic thoracoscopy and talc poudrage. There is no consensus as to which approach is most effective. Objective This trial tested the hypothesis that thoracoscopy and talc poudrage increases the proportion of patients with successful pleurodesis at 3 months post procedure, compared with chest drain insertion and talc slurry. Design This was a multicentre, open-label, randomised controlled trial with embedded economic evaluation. Follow-up took place at 1, 3 and 6 months. Setting This trial was set in 17 NHS hospitals in the UK. Participants A total of 330 adults with a confirmed diagnosis of malignant pleural effusion needing pleurodesis and fit to undergo thoracoscopy under local anaesthetic were included. Those adults needing a tissue diagnosis or with evidence of lung entrapment were exclS (evaluating the efficacy of Thoracoscopy And talc Poudrage versus Pleurodesis using talc Slurry) trial has robustly demonstrated that there is no additional clinical effectiveness or cost-effectiveness benefit in performing talc poudrage at thoracoscopy over bedside chest drain and talc slurry for the management of malignant pleural effusion.

Planning for a return to normality or the new normal is a complex, multi-agency task for which healthcare scientists may not be prepared. This paper introduces a widely used military planning framework known as the Joint Military Appreciation Process, and outlines how it can be applied to deal with the next phase of the COVID-19 pandemic. Recognition of SARS-CoV-2's critical attributes, targetable vulnerabilities, and its most likely and most dangerous effects is a necessary precursor to scoping, framing and mission analysis. From this flows course of action development, analysis, concept of operations development, and an eventual decision to act on the plan. The same planning technique is applicable to the larger scale task of setting a microbiology-centric plan in the broader context of social and economic recovery.The family Alphaflexiviridae includes viruses with flexuous filamentous virions that are 470-800 nm in length and 12-13 nm in diameter. Alphaflexiviruses have a single-stranded, positive-sense RNA genome of 5.5-9 kb. They infect plants and plant-infecting fungi. They share a distinct lineage of alphavirus-like replication proteins that is unusual in lacking any recognized protease domain. With a single exception, cell-to-cell and long-distance movement is facilitated by triple gene block proteins in plant-infecting genera. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Alphaflexiviridae, which is available at www.ictv.global/report/alphaflexiviridae.A Gram-stain-negative, yellow-pigmented, aerobic, non-spore-forming, motile with a single polar flagellum and rod-shaped bacterium, Ji-3-8T, was isolated from a soil sample taken from Jiri Mountain, Republic of Korea. Comparative 16S rRNA gene sequence studies showed the isolate had clear affiliation with Alphaproteobacteria and the closest relatedness to Caulobacter rhizosphaerae KCTC 52515T, Caulobacter henricii ATCC 15253T, Caulobacter segnis ATCC 21756T, Caulobacter hibisci THG-AG3.4T, Caulobacter flavus RHGG3T and Caulobacter vibrioides CB51T showing 99.1, 98.9, 97.7, 97.6, 97.5 and 97.4 % 16S rRNA gene sequence similarity, respectively, and 94.7-96.5 % to the remaining species of genus Caulobacter. The predominant ubiquinone was Q-10 and the major fatty acids were C18 1 ω7c 11-methyl, C16 0, summed feature 8 (C18 1 ω6c and/or C18 1 ω7c) and summed feature 3 (C16 1 ω6c and/or C16 1 ω7c). The major polar lipids were found to be phosphatidylglycerol, two unidentified phosphoglycolipid and two unidentified glycolipids. The G+C content of the genomic DNA of strain Ji-3-8T was 68.1 mol%. Average nucleotide identity and digital DNA-DNA hybridization values of strain Ji-3-8T with C. rhizosphaerae KCTC 52515T, C. henricii ATCC 15253T, C. segnis ATCC 21756T, C. flavus RHGG3T and C. vibrioides were 79.7-87.7% and 23.0-34.3%, respectively. Based on the polyphasic evidence, it is proposed that strain Ji-3-8T forms a novel species in the genus Caulobacter, for which the name Caulobacter soli sp. nov. is proposed. The type strain is Ji-3-8T (=CCTCC AB 2019389T=KCTC 72990T).Domestication is a condition in which the breeding, care and feeding of animals are, at least in part, controlled by humans. Information regarding the changes in the protein composition of eggs in response to domestication is very limited. Such data are prerequisite for improvements in the reproduction of domesticated fish. The aim of this study was to examine the impact of domestication on the proteome of pikeperch eggs using two-dimensional differential in-gel electrophoresis. We analysed high-quality eggs from domesticated and wild pikeperch fish to reveal proteins that were presumably only related to the domestication process and not to the quality of eggs. Here, we show that domestication has a profound impact on the protein profile of pikeperch eggs. We identified 66 differentially abundant protein spots, including 27 spots that were more abundant in wild-caught pikeperch eggs and 39 spots that were enriched in eggs collected from domesticated females. Eggs originating from wild-caught females showed higher expression levels of proteins involved in folding, apoptotic process, purine metabolism and immune response, whereas eggs of domesticated females showed higher expression levels of proteins that participated mainly in metabolism. The changes in metabolic proteins in eggs from domesticated females can reflect the adaptation of pikeperch to commercial diets, which have profoundly distinct compositions compared with natural diets. The decrease in the abundance of proteins related to immune response in eggs from the domesticated population suggests that domestication may lead to disturbances in defence mechanisms. In turn, the lower abundance of heat shock proteins in eggs of domesticated fish may indicate their adaptation to stable farming conditions and reduced environmental stressors or their better tolerance of stress from breeding. The proteins identified in this study can increase our knowledge concerning the mechanism of the pikeperch domestication process.
