Transurethral and suprapubic mesh resection after Prolift® bladder perforation: a case report
Bladder perforation is a complication which can occur after a Prolift® procedure and may enhance vesicovaginal fistula formation. Different methods of management of bladder perforation caused by mesh procedures are described in the literature, and most authors advise complete excision of the mesh. In the case described in this article, we propose a combined transurethral and suprapubical approach as the optimal method for maximal tape removal, being both minimally invasive and less damaging to the vesical wall. A suprapubical catheter can be removed shortly after surgery to enable optimal tissue healing of the vesical mucosa
Антибіотикопрофілактика в хірургії
Наук. кер.: М.Г. КононенкоГнійно-запальні післяопераційні ускладнення за останні десятиріччя набувають все більшої актуальності. Це вже стає проблемою. Такі ускладнення необхідно попереджувати. Для забезпечення тканин операційного поля антибіотиком у ефективній (бактерицидній) концентрації на весь період хірургічного втручання проводять антибіотикопрофілактику (АБП). Вона є складовою частиною комплексної профілактики гнійно-запальних ускладнень.

Identification of losses to follow-up in a community-based antiretroviral therapy clinic in South Africa using a computerized pharmacy tracking system
BACKGROUND: High rates of loss to follow-up (LTFU) are undermining rapidly expanding antiretroviral treatment (ART) services in sub-Saharan Africa. The intelligent dispensing of ART (iDART) is an open-source electronic pharmacy system that provides an efficient means of generating lists of patients who have failed to pick-up medication. We determined the duration of pharmacy delay that optimally identified true LTFU. METHODS: We conducted a retrospective cross-sectional study of a community-based ART cohort in Cape Town, South Africa. We used iDART to identify groups of patients known to be still enrolled in the cohort on the 1st of April 2008 that had failed to pick-up medication for periods of ≥ 6, ≥ 12, ≥ 18 and ≥ 24 weeks. We defined true LTFU as confirmed failure to pick up medication for 3 months since last attendance. We then assessed short-term and long-term outcomes using a prospectively maintained database and patient records. RESULTS: On the date of the survey, 2548 patients were registered as receiving ART but of these 85 patients (3.3%) were found to be true LTFU. The numbers of individuals (proportion of the cohort) identified by iDART as having failed to collect medication for periods of ≥ 6, ≥ 12, ≥ 18 and ≥ 24 weeks were 560 (22%), 194 (8%), 117 (5%) and 80 (3%), respectively. The sensitivities of these pharmacy delays for detecting true LTFU were 100%, 100%, 62.4% and 47.1%, respectively. The corresponding specificities were 80.7%, 95.6%, 97.4% and 98.4%. Thus, the optimal delay was ≥ 12 weeks since last attendance at this clinic (equivalent to 8 weeks since medication ran out). Pharmacy delays were also found to be significantly associated with LTFU and death one year later. CONCLUSIONS: The iDART electronic pharmacy system can be used to detect patients potentially LTFU and who require recall. Using a short a cut-off period was too non-specific for LTFU and would require the tracing of very large numbers of patients. Conversely prolonged delays were too insensitive. Of the periods assessed, a ≥ 12 weeks delay appeared optimal. This system requires prospective evaluation to further refine its utility
P15-13. HVTN 503(Phambili) trial discontinuation of enrolment/vaccination: the impact on trial participant attitudes to vaccine trials and scientific research
Background: The HVTN 503/Phambili trial, a phase IIB study of the Merck Ad-5 HIV vaccine, suspended enrollment and vaccinations following results of the HVTN502/STEP study. Participants were notified of their treatment allocation and continue to be followed. We investigated the impact of the suspension on trial participants' attitudes towards HIV vaccine trials and scientific research. Methods: A self-administered questionnaire investigating knowledge and attitudes utilising a five-point likert scale, was administered 12–18 months post suspension at the 4 Phambili trial sites implementing the latest protocol. Results: Of 544 participants enrolled at 4 sites, 490 completed the questionnaire. 51% understood that vaccination, and 31% that enrolment had been permanently discontinued. Although 85% knew Phambili DSMB recommendations were based on results of the STEP study, only 51% knew that the results showed more infections in the vaccine arm. Although 90% knew they should continue protecting themselves against HIV, only 33% acknowledged trialists' concerns that the vaccine may make them more susceptible to HIV. Knowledge was similar across sites. 12% had tested for HIV antibodies outside of the trial before unblinding to establish their treatment allocation. 46% felt disappointed, angry or afraid, primarily because the vaccine would not prevent HIV in their community. 79% said they would engage in less risk behaviour. 94% thought the study team had made the correct decision by unblinding them and 96% thought site-participant communication was appropriate. 91% felt they made the right decision to enrol in Phambili and 91% planned to continue attending scheduled visits. 86% support scientific research and 80% would want to participate in future HIV vaccine. Conclusion: Despite site communications, knowledge levels were low. Importantly, most knew they should continue to protect themselves against HIV. Although almost half of participants reported negative feelings, most attitudes towards trial sites, scientific research and HIV vaccine trials were positive

Needs and opportunities in mineral evolution research
Progress in understanding mineral evolution, Earth’s changing near-surface mineralogy through time, depends on the availability of detailed information on mineral localities of known ages and geologic settings. A comprehensive database including this information, employing the mindat.org web site as a platform, is now being implemented. This resource will incorporate software to correlate a range of mineral occurrences and properties vs. time, and it will thus facilitate studies of the chang- ing diversity, distribution, associations, and characteristics of individual minerals as well as mineral groups. The Mineral Evolution Database thus holds the prospect of revealing mineralogical records of important geophysical, geochemical, and biological events in Earth history.Organismic and Evolutionary Biolog
Correlators of Giant Gravitons from dual ABJ(M) Theory
We generalize the operators of ABJM theory, given by Schur polynomials, in
ABJ theory by computing the two point functions in the free field and at finite
limits. These polynomials are then identified with the states of
the dual gravity theory. Further, we compute correlators among giant gravitons
as well as between giant gravitons and ordinary gravitons through the
corresponding correlators of ABJ(M) theory. Finally, we consider a particular
non-trivial background produced by an operator with an -charge of
and find, in presence of this background, due to the contribution of
the non-planar corrections, the large expansion is replaced by
and respectively.Comment: Latex, 32+1 pages, 2 figures, journal versio
