Where should bulking agents for female urodynamic stress incontinence be injected?

For bulking agents used for female stress urinary incontinence, the recommendation for the anatomical placement varies as some injectables are to be placed close to the bladder neck and others midurethrally. Aim of the study was to determine if there are differences concerning the outcome after transurethral collagen injections depending on the anatomical placement midurethrally or at the bladder neck. We randomly assigned 30 elderly female patients with urodynamic stress incontinence to either transurethral collagen injection midurethrally or to the bladder neck. Prior to injection and at ten month follow-up, maximum urethral closure pressure (MUCP), functional urethral length (FUL), maximum flow rate and cough test were performed and the patient was asked to estimate her bladder condition using a visual analogue scale. Postoperative contentness was 8 (median, 95% confidence interval 5-9) in the midurethral group and 8 (median, 95% confidence interval 7-10) in the bladder neck group with a p value of 0.012, 95% confidence interval -2.464 to -0.2859, in favour to midurethral injections. MUCP and FUL increased significantly in both groups and flow rate decreased in both groups. Continence was 66.6% in the midurethral group and 60% for the bladder neck group respectively. Both midurethral and bladder neck collagen injections improve patients' satisfaction almost equally with a small advantage for midurethral injection

CONDIÇÕES SOCIAIS PARA A FORMAÇÃO DO CONHECIMENTO: COMO COMPREENDER O “FA ZER CIENTÍFICO”: CONSIDERAÇÕES SOBRE A POSIÇÃO EPISTEMOLÓGICA DE PIERRE BOURDIEU E JÜRGEN HABERMAS

RESUMO: O presente trabalho discute “o fazer científico” da Sociologia, indicando algumas modificações importantes na forma de construção do conhecimento. Neste sentido, são apresentadas percepções de dois pesquisadores (Bourdieu e Habermas) que partindo de bases epistemológicas diferentes, indicam que é preciso desacomodar os pesquisadores sociais da sua posição supostamente neutra em relação à produção do conhecimento

Bipartitions of Highly Connected Tournaments

We show that if $T$ is a strongly $10^9k^6\log(2k)$-connected tournament, there exists a partition $A, B$ of $V(T)$ such that each of $T[A]$, $T[B]$ and $T[A,B]$ is strongly $k$-connected. This provides tournament analogues of two partition conjectures of Thomassen regarding highly connected graphs.Comment: The main result of the current version strengthens the previous on

On the random greedy F-free hypergraph process

Let $F$ be a strictly $k$-balanced $k$-uniform hypergraph with $e(F)\geq |F|-k+1$ and maximum co-degree at least two. The random greedy $F$-free process constructs a maximal $F$-free hypergraph as follows. Consider a random ordering of the hyperedges of the complete $k$-uniform hypergraph $K_n^k$ on $n$ vertices. Start with the empty hypergraph on $n$ vertices. Successively consider the hyperedges $e$ of $K_n^k$ in the given ordering, and add $e$ to the existing hypergraph provided that $e$ does not create a copy of $F$. We show that asymptotically almost surely this process terminates at a hypergraph with $\tilde{O}(n^{k-(|F|-k)/(e(F)-1)})$ hyperedges. This is best possible up to logarithmic factors
