Iatrogenic tube jejunostomy complicating suprapubic cystostomy: A case report

Suprapubic cystostomy (SPC) can be done by open or percutaneous technique. The procedure is considered simple and generally safe even in less experienced hands. However, some complications may arise occasionally, including bowel injury. We report a 60-year-old man who presented with acute-on-chronic urinary retention 6 months after a SPC in a peripheral hospital for chronic urinary retention. The catheter was draining scanty turbid fluid and was changed regularly. Abdominal exploration revealed an intact full bladder with the supposed suprapubic catheter passing through a small perforation into the jejunum. He had repair of the perforation and proper SPC was inserted. The recovery was uneventful, and he was discharged home after a week.Keywords: suprapubic cystostomy; complications; bowel injury; tube jejunostom

Weak entanglement improves quantum communication using only passive linear optics

We show that noisy entangled states, that cannot violate any Bell inequality, can be used to improve quantum communication when measurements are limited to being compatible with standard, ancilla-free, linear optics. We introduce a communication task inspired by the cryptographic primitive known as secret sharing and show that entanglement that is too weak to permit possible Einstein-Podolsky-Rosen steering can still enhance the success rate when using only standard partial Bell state analysers for decoding. We then go further and show that even the simplest type of decoding, namely product measurements, which require no optical interference at all, can still lead to an advantage when the entanglement is steerable but still Bell-local. We demonstrate the former advantage by preparing polarisation qubits in an unsteerable entangled state and by using only beam-splitters and phase-shifters observing a boost in the success rate of beyond the best entanglement-unassisted qubit protocol

Management of obstructive nephropathy in a tertiary hospital in North West Nigeria: A five-year review

Background: Obstructive nephropathy is managed initially with urinary diversion and possibly haemodialysis before definitive therapy. This study was aimed at determining the pattern of presentation, aetiology and management options of obstructive nephropathy in our practice.Methods: This was a five-year retrospective study of the patients managed for obstructive nephropathy at our facility from January 2011-December 2015. Data were collected via a pro forma and analysed using SPSS version 20.0.Results: There were 106 patients managed for obstructive nephropathy with a mean age of 48.3 ± 17. 4 years and age range of 4 months to 85 years. The male: female ratio was 10:1. The most common causes of obstructive nephropathy were bladder cancer (49.1%), benign prostatic hyperplasia (BPH, 22.6%), bilateral ureteric stone (5.7%) and bilateral schistosomal lower ureteric obstruction (4.7%). Urethral or suprapubic catheterisation (22.6%), nephrostomy (2.8%) and dialysis (10.4%) were the initial treatments. Chemoradiation was done for the patients with bladder cancer and 17.9% of the patients had operative interventions, which included ureteroneocystostomy, open prostatectomy or transurethral resection of the prostate, and ureteroscopy + lithotripsy. Fifty-two patients (49.1%) died while awaiting dialysis and four patients (3.8%) developed end-stage renal disease.Conclusions: Bladder carcinomas, BPH, ureteric obstruction are the commonest causes of obstructive nephropathy in our practice. The initial treatment includes urinary diversion and or dialysis before definitive treatment.Keywords: obstructive nephropathy; bladder cancer; acute kidney injury; chronic kidney injury; urinary diversion; dialysi

Coherent states for polynomial su(1,1) algebra and a conditionally solvable system

In a previous paper [{\it J. Phys. A: Math. Theor.} {\bf 40} (2007) 11105], we constructed a class of coherent states for a polynomially deformed $su(2)$ algebra. In this paper, we first prepare the discrete representations of the nonlinearly deformed $su(1,1)$ algebra. Then we extend the previous procedure to construct a discrete class of coherent states for a polynomial su(1,1) algebra which contains the Barut-Girardello set and the Perelomov set of the SU(1,1) coherent states as special cases. We also construct coherent states for the cubic algebra related to the conditionally solvable radial oscillator problem.Comment: 2 figure

A New Conjugate Gradient Coefficient for Unconstrained Optimization Based On Dai-Liao

This paper, proposes a new conjugate gradient method for unconstrained optimization based on Dai-Liao (DL) formula; descent condition and sufficient descent condition for our method are provided. The numerical results and comparison show that the proposed algorithm is potentially efficient when we compare with (PR) depending on number of iterations (NOI) and the number of functions evaluation (NOF)

Impact of DWDM at 50GHz spacing in the 2µm waveban

In this paper, we show for the first time the impact of decreasing DWDM channel spacing to 50GHz in the 2mm waveband, using 6x12.5Gbit/s and 2x8Gbit/s OOK signals

The Spread of HIV in Pakistan: Bridging of the Epidemic between Populations

In the last two decades, ‘concentrated epidemics’ of human immunodeficiency virus (HIV) have established in several high risk groups in Pakistan, including Injecting Drug Users (IDUs) and among men who have sex with men (MSM). To explore the transmission patterns of HIV infection in these major high-risk groups of Pakistan, 76 HIV samples were analyzed from MSM, their female spouses and children, along with 26 samples from a previously studied cohort of IDUs. Phylogenetic analysis of HIV gag gene sequences obtained from these samples indicated a substantial degree of intermixing between the IDU and MSM populations, suggesting a bridging of HIV infection from IDUs, via MSM, to the MSM spouses and children. HIV epidemic in Pakistan is now spreading to the female spouses and offspring of bisexual MSM. HIV control and awareness programs must be refocused to include IDUs, MSM, as well as bisexual MSM, and their spouses and children

SPARC 2019 Fake news & home truths : Salford postgraduate annual research conference book of abstracts

Welcome to the Book of Abstracts for the 2019 SPARC conference. This year we not only celebrate the work of our PGRs but also our first ever Doctoral School Best Supervisor awards, which makes this year’s conference extra special. Once again we have received a tremendous contribution from our postgraduate research community; with over 90 presenters, the conference truly showcases a vibrant, innovative and collaborative PGR community at Salford. These abstracts provide a taster of the inspiring, relevant and impactful research in progress, and provide delegates with a reference point for networking and initiating critical debate. Find an abstract that interests you, and say “Hello” to the author. Who knows what might result from your conversation? With such wide-ranging topics being showcased, we encourage you to take up this great opportunity to engage with researchers working in different subject areas from your own. To meet global challenges, high impact research needs interdisciplinary collaboration. This is recognised and rewarded by all major research funders. Engaging with the work of others and forging collaborations across subject areas is an essential skill for the next generation of researchers. Even better, our free ice cream van means that you can have those conversations while enjoying a refreshing ice lolly
