Additional secure circular suture during sphincteroplasty — preliminary results on the efficacy of fecal incontinence surgery in urogynecological patients

Objectives: The paper is a ten case series study presenting women with complex pelvic floor disorders involving fecal incontinence (FI) with stress urinary incontinence or pelvic organ prolapse.  Our study aimed at ascertaining whether FI-induced sphincteroplasty with an additional secure circular suture around the external anal sphincter muscle (EAS) may improve long term success rates.  Materials and methods: Twelve patients had scheduled urogynecological surgery and overlapping sphincteroplasty with the placement of an additional circular suture around the EAS. Of these, the status of ten women was established by way of the Cleveland Clinic Fecal Incontinence Score/Wexner Score before and about 70 months after surgery.  Results: Statistical analysis of fecal incontinence score showed that patients were not completely cured from FI, but were significantly better (p = 0.011).  Conclusions: A circular secure suture around the external anal sphincter in FI patients may help to improve anal sphincter function. 

Enhancing of catalytic properties of vanadia via surface doping with phosphorus using atomic layer deposition

A 34, 01A135 (2016) and may be found at https://doi.org/10.1116/1.4936390.Atomic layer deposition is mainly used to deposit thin films on flat substrates. Here, the authors deposit a submonolayer of phosphorus on V2O5 in the form of catalyst powder. The goal is to prepare a model catalyst related to the vanadyl pyrophosphate catalyst (VO)2P2O7 industrially used for the oxidation of n-butane to maleic anhydride. The oxidation state of vanadium in vanadyl pyrophosphate is 4+. In literature, it was shown that the surface of vanadyl pyrophosphate contains V5+ and is enriched in phosphorus under reaction conditions. On account of this, V2O5 with the oxidation state of 5+ for vanadium partially covered with phosphorus can be regarded as a suitable model catalyst. The catalytic performance of the model catalyst prepared via atomic layer deposition was measured and compared to the performance of catalysts prepared via incipient wetness impregnation and the original V2O5 substrate. It could be clearly shown that the dedicated deposition of phosphorus by atomic layer deposition enhances the catalytic performance of V2O5 by suppression of total oxidation reactions, thereby increasing the selectivity to maleic anhydride.DFG, 53182490, EXC 314: Unifying Concepts in Catalysi

Older Adults and Voice Interaction: A Pilot Study with Google Home

In this paper we present the results of an exploratory study examining the potential of voice assistants (VA) for some groups of older adults in the context of Smart Home Technology (SHT). To research the aspect of older adults' interaction with voice user interfaces (VUI) we organized two workshops and gathered insights concerning possible benefits and barriers to the use of VA combined with SHT by older adults. Apart from evaluating the participants' interaction with the devices during the two workshops we also discuss some improvements to the VA interaction paradigm

Perspectives for the pharmacological treatment of overactive bladder syndrome

It has been found that antimuscarinic drugs, viewed as the “gold standard” in overactive bladder syndrome (OAB) treatment, have an unsatisfactory tolerance profile and limited clinical effectiveness. This fact has given a clear impetus to search for new options in OAB pharmacotherapy. The conducted pre-clinical trials have led to the development of new solutions for the treatment of OAB, which stand a good chance of being applied in clinical practice. The said compounds are characterised by higher receptor and organ specificity than currently used medications

Does intraoperative application of TachoSil reduce the number of lymphoceles after pelvic lymphadenectomy?

Objectives: The degree of lymphoceles prevention was assessed using collagen patches coated with human coagulation factors (TachoSil, Nycomed International Management GmbH, Zurich, Switzerland). The study enrolled 50 consecutive patients with endometrial and cervical cancer stages IB to II who had undergone open hysterectomy and pelvic lymphadenectomy (PL). In addition, the drainage volumes of 22 patients with hypertension were compared to that of the rest of the study population. Furthermore, occurrence of lymphocele in patients with endometrial and cervical cancer were compared after completion of adjuvant treatment. Material and methods: Patients were simultaneously randomized in two groups: as a control (side without TachoSil applied) and study group (side with TachoSil applied). All surgical parameters were collected, and patients underwent ultrasound examination on postoperative days 1, 6, and 30, and at the end of treatment. Results: The TachoSil Group showed a lower drainage volume, 30 days after surgery, while outflow of fluid occurred in 11 (22%) of all TachoSil Group cases and 22 (44%) of all control group cases. Furthermore, two patients in the control group had symptomatic lymphocele, while the same number of cases was observed in the TachoSil Group. However, the TachoSil Group demonstrated a decreased tendency to lymphocele occurrence after the end of adjuvant therapy. Here, patients with the collagen patch developed lymphocele in 12% of all cases, as opposed to 18% without TachoSil. Conclusions: TachoSil is a useful support treatment option for reducing drainage volume and preventing lymphocele development after lymphadenectomy

VR Accessibility in Distance Adult Education

As virtual reality (VR) technology becomes more pervasive, it continues to find multiple new uses beyond research laboratories. One of them is distance adult education -- the potential of VR to provide valuable education experiences is massive, despite the current barriers to its widespread application. Nevertheless, recent trends demonstrate clearly that VR is on the rise in education settings, and VR-only courses are becoming more popular across the globe. This trend will continue as more affordable VR solutions are released commercially, increasing the number of education institutions that benefit from the technology. No accessibility guidelines exist at present that are created specifically for the design, development, and use of VR hardware and software in distance education. The purpose of this workshop is to address this niche. It gathers researchers and practitioners who are interested in education and intend to work together to formulate a set of practical guidelines for the use of VR in distance adult education to make it accessible to a wider range of people.Comment: 7 pages, 1 figur
