Male Stress Urinary Incontinence: A Review of Surgical Treatment Options and Outcomes
Introduction and Objective. Iatrogenic male stress urinary incontinence (SUI) affects a percentage of men undergoing urologic procedures with a significant impact on quality of life. The treatment of male SUI has evolved significantly with multiple current options for treatment available. The current paper discusses preoperative evaluation of male SUI, available surgical options with reported outcomes, and postoperative complication management. Methods. A pubMed review of available literature was performed and summarized on articles reporting outcomes of placement of the artificial urinary sphincter (AUS) or male slings including the bone anchored sling (BAS), retrourethral transobturator sling (RTS), adjustable retropubic sling (ARS), and quadratic sling. Results. Reported rates of success (variably defined) for BAS, RTS, ARS, and AUS are 36–67%, 9–79%, 13–100%, and 59–91% respectively. Complications reported include infection, erosion, retention, explantation, and transient pain. Male slings are more commonly performed in cases of low-to-moderate SUI with decreasing success with higher degrees of preoperative incontinence. Conclusions. An increasing number of options continue to be developed for the management of male SUI. While the AUS remains the gold-standard therapy for SUI, male sling placement is a proven viable alternative therapy for low-to-moderate SUI

Early renal failure after domino hepatic transplantation using the liver from a compound heterozygous patient with primary hyperoxaluria
Background. To cover the shortage of cadaveric organs, new approaches to expand the donor pool are needed. Here we report on a case of domino liver transplantation (DLT) using an organ harvested from a compound heterozygous patient with primary hyperoxaluria (PHO), who underwent combined liver and kidney transplantation. The DLT recipient developed early renal failure with oxaluria. The time to the progression to oxalosis with renal failure in such situations is unknown, but, based on animal data, we hypothesize that calcineurin inhibitors may play a detrimental role. Methods. A cadaveric liver and kidney transplantation was performed in a 52-year-old male with PHO. His liver was used for a 64-year-old patient with a non-resectable, but limited cholangiocarcinoma. Results. While the course of the PHO donor was uneventful, in the DLT recipient early post-operative, dialysis-dependent renal failure with hyperoxaluria developed. Histology of a kidney biopsy revealed massive calcium oxalate crystal deposition as the leading aetiological cause. Conclusions. DLT using PHO organs for marginal recipients represents a possible therapeutic approach regarding graft function of the liver. However, it may negatively alter the renal outcome of the recipient in an unpredictable manner, especially with concomitant use of cyclosporin. Therefore, we suggest that, although DLT should be promoted, PHO organs are better excluded from such procedure
Expedient synthesis of an atypical oxazolidinone compound library
In order to address the current downturn in the drug discovery pipeline, initiatives are being undertaken to synthesise screening libraries of sp3-rich, low molecular weight compounds. As part of the European Lead Factory initiative, the synthesis and derivatisation of a simple hexahydrooxazolo[5,4-c]pyridin-2(1H)-one bicyclic carbamate has been achieved. The synthetic route employed involved a telescoped hetero-Diels-Alder/[2,3]-sigmatropic rearrangement/cyclisation sequence to deliver the desired core scaffold containing two points for further diversification. When applied, this synthesis was found to be robust and scalable which allowed the production of a 155 compound library
Kassiopeia: A Modern, Extensible C++ Particle Tracking Package
The Kassiopeia particle tracking framework is an object-oriented software
package using modern C++ techniques, written originally to meet the needs of
the KATRIN collaboration. Kassiopeia features a new algorithmic paradigm for
particle tracking simulations which targets experiments containing complex
geometries and electromagnetic fields, with high priority put on calculation
efficiency, customizability, extensibility, and ease of use for novice
programmers. To solve Kassiopeia's target physics problem the software is
capable of simulating particle trajectories governed by arbitrarily complex
differential equations of motion, continuous physics processes that may in part
be modeled as terms perturbing that equation of motion, stochastic processes
that occur in flight such as bulk scattering and decay, and stochastic surface
processes occuring at interfaces, including transmission and reflection
effects. This entire set of computations takes place against the backdrop of a
rich geometry package which serves a variety of roles, including initialization
of electromagnetic field simulations and the support of state-dependent
algorithm-swapping and behavioral changes as a particle's state evolves. Thanks
to the very general approach taken by Kassiopeia it can be used by other
experiments facing similar challenges when calculating particle trajectories in
electromagnetic fields. It is publicly available at

Mutations that affect the surface expression of TRPV6 are associated with the upregulation of serine proteases in the placenta of an infant
Recently, we reported a case of an infant with neonatal severe under-mineralizing skeletal dysplasia caused by mutations within both alleles of the TRPV6 gene. One mutation results in an in frame stop codon (R(510)stop) that leads to a truncated, nonfunctional TRPV6 channel, and the second in a point mutation (G(660)R) that, surprisingly, does not affect the Ca(2+) permeability of TRPV6. We mimicked the subunit composition of the unaffected heterozygous parent and child by coexpressing the TRPV6 G(660)R and R(510)stop mutants and combinations with wild type TRPV6. We show that both the G(660)R and R(510)stop mutant subunits are expressed and result in decreased calcium uptake, which is the result of the reduced abundancy of functional TRPV6 channels within the plasma membrane. We compared the proteomic profiles of a healthy placenta with that of the diseased infant and detected, exclusively in the latter two proteases, HTRA1 and cathepsin G. Our results implicate that the combination of the two mutant TRPV6 subunits, which are expressed in the placenta of the diseased child, is responsible for the decreased calcium uptake, which could explain the skeletal dysplasia. In addition, placental calcium deficiency also appears to be associated with an increase in the expression of proteases

EELISA Credential: The Recognition Of Commitment And Impact In The Addressing Of Societal Challenges In The EELISA Alliance
EELISA Credential is a unique recognition process provided to EELISA students, professional and alumni who are part of the mission-driven EELISA communities and reflects the commitment and impact level achieved in the addressing of a societal challenge.
The EELISA Credential is an individual, progressive environment on which students collect badges. These badges are acquired after verifying the achievement of an educational outcome level after participating in community\u27s educational activities. A badge represents the unit of learning acquisition and impact that corresponds to an educational outcome. It is reflected in the EELISA Credential which itself refers to an impact level and a Sustainable Development Goal (SDG).
The impact level represents the badge measurement scale. In the EELISA Credential, there are 5 levels of impact (discovery, knowledge, engagement, action, transformation) that correspond to learning objectives relative to SDGs.
The education activities proposed by EELISA Communities are defined around a societal challenge defined by a problem owner (faculty, students, local communities). Each activity is centered in 1 or 2 SDGs, and recognizes a maximum of 4 badges.
Through the involvement in the activities of EELISA Communities, students enrich their EELISA Credential in areas addressing Sustainable Developments Goals (SDGs), progressively improving their capacity for understanding, action and transformation.
In this practice paper, we will present the requirements for activities to be part of the EELISA Credential, representative and successful activities, the Quality Assurance system, the lessons learnt in the process of implementing the credential and how EELISA Credential will evolve in the future
