Comparison of open and robotic-assisted partial nephrectomy approaches using multicentric data (UroCCR-47 study)

We compared the outcomes of robotic-assisted partial nephrectomy (RPN) and open partial nephrectomy (OPN) using contemporary data to respond to unmet clinical needs. Data from patients included in the registry who underwent partial nephrectomy between January 01, 2014 and June 30, 2017 within 20 centres of the French Network for Research on Kidney Cancer UroCCR were collected (NCT03293563). Statistical methods included adjusted multivariable analyses. Rates of peri- and post-operative transfusion, and of surgical revision, were lower in the RPN (n = 1434) than the OPN (n = 571) group (2.9% vs. 6.0%, p = 0.0012; 3.8% vs. 11.5%, p < 0.0001; 2.4% vs. 6.7%, p < 0.0001, respectively). In multivariable analyses, RPN was independently associated with fewer early post-operative complications than OPN (overall: odds-ratio [95% confidence interval, CI] = 0.48 [0.35–0.66]; severe: 0.29 [0.16–0.54], p < 0.0001 for both) and shorter hospital stays (34% [30%; 37%], p < 0.0001). RPN was also a significantly associated with a decresedrisk of post-operative acute renal failure, and new-onset chronic kidney disease at 3 and 12 months post-surgery. There were no between-group differences in oncological outcomes. In comparison with OPN, RPN was associated with improved peri- and post-operative morbidity, better functional outcomes, and shorter hospital stays. Our results support the use of RPN, even for large and complex tumours

Genome of Diuraphis noxia, a global aphid pest of small grains

Background: The Russian wheat aphid, Diuraphis noxia Kurdjumov, is one of the most important pests of small grains throughout the temperate regions of the world. This phytotoxic aphid causes severe systemic damage symptoms in wheat, barley, and other small grains as a direct result of the salivary proteins it injects into the plant while feeding.Results: We sequenced and de novo assembled the genome of D. noxia Biotype 2, the strain most virulent to resistance genes in wheat. The assembled genomic scaffolds span 393 MB, equivalent to 93% of its 421 MB genome, and contains 19,097 genes. D. noxia has the most AT-rich insect genome sequenced to date (70.9%), with a bimodal CpG(O/E) distribution and a complete set of methylation related genes. The D. noxia genome displays a widespread, extensive reduction in the number of genes per ortholog group, including defensive, detoxification, chemosensory, and sugar transporter groups in comparison to the Acyrthosiphon pisum genome, including a 65% reduction in chemoreceptor genes. Thirty of 34 known D. noxia salivary genes were found in this assembly. These genes exhibited less homology with those salivary genes commonly expressed in insect saliva, such as glucose dehydrogenase and trehalase, yet greater conservation among genes that are expressed in D. noxia saliva but not detected in the saliva of other insects. Genes involved in insecticide activity and endosymbiont-derived genes were also found, as well as genes involved in virus transmission, although D. noxia is not a viral vector.Conclusions: This genome is the second sequenced aphid genome, and the first of a phytotoxic insect. D. noxia's reduced gene content of may reflect the influence of phytotoxic feeding in shaping the D. noxia genome, and in turn in broadening its host range. The presence of methylation-related genes, including cytosine methylation, is consistent with other parthenogenetic and polyphenic insects. The D. noxia genome will provide an important contrast to the A. pisum genome and advance functional and comparative genomics of insects and other organisms.Peer reviewedBiochemistry and Molecular Biolog

Sequential treatment with ProACT™ device implantation after male sling failure for male urinary incontinence

International audienceThere is no strong evidence for second line therapy after male sling failure for post-prostatectomy urinary incontinence (PPUI). We report the outcomes after periurethral balloons implantation for persistence or recurrence of mild PPI symptoms after male sling implantation.L’inefficacité d’une bandelette sous-urétrale TOMS dans le traitement de l’incontinence urinaire légère à modérée amène à rechercher des alternatives thérapeutiques de seconde intention. Il existe très peu de données sur la pose de ballons ACT après bandelette sous-urétrale

Robot-assisted orthotopic “W” ileal neobladder in male patients: step-by-step video-illustrated technique and preliminary outcomes

The objective\ua0was\ua0to describe our step-by-step technique for robot-assisted orthotopic “W” ileal neobladder (INB) for urinary diversion following radical cystectomy for oncological purpose, and to report the outcomes of this technique for the first six male\ua0patients treated at our center. Patients underwent robot-assisted radical cystoprostatectomy for bladder cancer and had a “W” ileal neaobladder as urinary diversion. Our surgical technique is described step by step and video illustrated. Patients and operative data were collected and reported. The Expanded Prostate Cancer Index Composite Short Form (EPIC-26) self-administered questionnaire was used to assess the urinary, sexual and bowel functions outcomes at 90\ua0days postoperatively. The mean operative time was 475\ua0min [420–525] and mean length of stay was 13\ua0days [11–15]. No major complications occurred (Clavien grade ≥ 3). Regarding the continence four patients reported they leaked urine rarely or never and two patients having urine leak once a day. Two patients did not wear any pad, the four others reported using pad at night. Two patients reported urinary function as not a problem, one as a very small problem, two as a small problem and one as a moderate problem. These results from our six first cases using the technique described here are promising with interesting early functional outcomes. This has to be confirmed on larger cohort and with long-term follow-up

Long-term outcomes of I-Stop TOMS™ male sling implantation for post-prostatectomy incontinence management

International audienceOBJECTIVES:To report long-term outcomes after I-Stop TOMS™ implantation for PPI.PATIENTS AND METHODS:A retrospective evaluation was conducted in three tertiary reference centers. All consecutive patients implanted with an I-Stop TOMS™ sling between 2007 and 2012 for mild to moderate PPI (24-hour Pad test<400g) without history of pelvic radiation therapy were included. Evaluation had been conducted preoperatively, at one and six months postoperative and yearly thereafter. The main outcome criterion was the number of pads per day. Secondary criteria were International Consultation on Incontinence Questionnaire (ICIQ), SF-36 questionnaire, and complications.RESULTS:A hundred patients were evaluated with a median follow-up of 58months [19-78]. Pad use was significantly reduced and quality of life improved at last follow-up (P<0.0001). The percentage of patients dry and socially continent (0 or 1 pad) were 40% and 77% at 1 year, then dropped to 15% and 22%, respectively after 5years. Twelve patients were treated by artificial urinary sphincter implantation, five by ProACT™ balloons and one by a re-do I-Stop TOMS™. No severe complications were recorded at last follow-up.CONCLUSIONS:I-Stop TOMS™ implantation is a safe and effective option in the short-term for mild to moderate PPI management. However, a significant trend to recurrence of leakage has been established after long-term follow-up. If confirmed by further studies, these results may substantially impact patient information before male sling implantation
