Východiska: Systematické review (SR) představuje v kontextu s přístupem a filozofií Evidence-Based Healthcare (EBHC) nejvýznamnější a nejhodnotnější typ studie v rámci úrovně vědeckých důkazů. Hallux valgus (HV) patří mezi nejčastější deformity v oblasti přednoží. SR, zabývající se vlivem operace HV na chůzi, kvalitu života, spokojenost a současně i bolest, ve světovém písemnictví chybí. Cíle: Hlavním cílem tohoto propedeuticky zaměřeného článku bylo poukázat na význam SR v rámci přístupu EBHC a přiblížit rigorózní a systematickou metodiku jeho tvorby příkladem dílčích výsledků SR zaměřeného na hodnocení efektu operační korekce deformity HV. Metodika: Nejprve jsme formulovali review otázku a specifikovali kritéria pro zařazení a vyloučení primárních studií do SR. Protokol SR jsme vypracovali pomocí softwaru, vyvinutého Joanna Briggs Institute pro tvorbu SR. Systematické vyhledávání publikovaných i nepublikovaných primárních studií zahrnovalo 3 kroky: 1. Iniciální vyhledávání v Medline, Embase a Cinahl; 2. sekundární vyhledávání v 13 databázích; 3. prostudování referenčních seznamů relevantních studií. Vyhledávali jsme randomizované kontrolované studie (RCT) bez časového omezení a ve všech jazycích. Výsledky: Celkem jsme nalezli 2412 studií a odstranili 767 duplikátů. Na základě dvoufázového hodnocení relevance a kritického hodnocení metodologické kvality studií pomocí standardizovaného hodnotícího nástroje JBI-MAStARI bylo zařazeno 27 RCT. V současné době probíhá extrakce výsledků pomocí standardizovaného nástroje JBI-MAStARI a příprava dat na meta-analýzu. Dílčí výsledky ukázaly nejednotnost použitých metod k hodnocení bolesti a spokojenosti pacientů po operaci HV v zahrnutých RCT. Závěry: SR představují velmi významné pojítko mezi vědeckými důkazy a jejich implementací do klinické praxe. Evidence-Based přístup je možné použít ve všech oblastech, v nichž se tvoří kvalitní primární vědecké důkazy., Background: Systematic review (SR), as secondary research is in the context of Evidence-Based Healthcare (EBHC) classified as the most important and valuable type of publication within the level of evidence hierarchy. Hallux valgus (HV) is a common forefoot deformity. In the current literature, there is no SR which has reviewed the effect of HV surgery on gait, pain or function in the global evidence. Aim: Main aim of this propedeutically focused paper was to highlight the importance of SR within EBHC approach and explain rigorous and systematic methods of its development by example of partial results of the SR focusing on evaluation of the effect of the hallux valgus surgery. Medhods: Firstly, we formulated an answerable review question and specified inclusion and exclusion criteria. Protocol of the SR was prepared using soware developed by Joanna Briggs Institute for SR preparation. Systematic search of published and unpublished studies included three steps: 1. Initial search in Medline, Embase and Cinahl; 2. secondary search in 13 databases; 3. hand-search in the reference lists of relevant papers. We have searched randomized controlled trials (RCT) in any date and language. Results: We found 2412 papers and deleted 767 duplicates. en a paper retrieval according to inclusion and exclusion criteria and critical appraisal of methodological quality were done using standardized critical appraisal instruments JBI-MAStARI. 27 RCT were included into SR. Currently, we are extracting data using JBI MAStARI and preparing them for meta-analysis. Partial results showed heterogeneity of used method for evaluation of pain and patient satisfaction aer HV surgery in included RCT. Conclusions: SR is a very important link between scientific evidence and their implementation into clinical practice. Evidence-Based approach can be used in all areas with high quality of primary scientific evidence., and Jitka Klugarová, Miloslav Klugar, Jana Marečková
We consider almost-complex structures on ℂP 3 whose total Chern classes differ from that of the standard (integrable) almost-complex structure. E. Thomas established the existence of many such structures. We show that if there exists an ''exotic'' integrable almost-complex structures, then the resulting complex manifold would have specific Hodge numbers which do not vanish. We also give a necessary condition for the nondegeneration of the Frölicher spectral sequence at the second level.
We studied the potassium channel in the basolateral membrane of the rat proximal convoluted tubule as affected by cyclosporine A. Proximal convoluted tubules were dissected from the rat kidney under a stereoscopic microscope, without a preliminary enzyme treatment. The standard configuration for single-channel tight seal patch-clamp technique
was used to record channel currents. A small conductance, stretch-sensitive potassium channel could be observed spontaneously in most of the cell-attached patches as the gigaohm seal was formed. In the inside-out configuration, channel activity was diminished. The K+
channel appeared to be an inward rectifier. The limiting inward slope
conductance was 28.3±1.7 pS (Vp was between 40 mV and 80 mV, n=6) and the outward chord conductance was 5.6±0.3 pS (Vp was between -40 and -60 mV, n=5). The open dwell time constants of the potassium channel were 0.524 ms and 5.087 ms, while the closed dwell time constants were 1.029 ms and 16.500 ms. The opening probability of the
channel decreased when the extracellular fluid was acidified. Cyclosporine A had no significant effect on the potassium channel of the proximal tubular cell in the basolateral membrane at concentrations of 10 and 50 μg/ml, while at 100 μg/ml, it decreased the opening probability.
Let $f$ be a transcendental meromorphic function. We propose a number of results concerning zeros and fixed points of the difference $g(z)=f(z+c)-f(z)$ and the divided difference $g(z)/f(z)$.
The paper extends the results given by M. Křížek and L. Somer, {\it On a connection of number theory with graph theory}, Czech. Math. J. 54 (129) (2004), 465--485 (see [5]). For each positive integer $n$ define a digraph $\Gamma (n)$ whose set of vertices is the set $H=\{0,1,\dots ,n - 1\}$ and for which there is a directed edge from $a\in H$ to $b\in H$ if $a^3\equiv b\pmod n.$ The properties of such digraphs are considered. The necessary and the sufficient condition for the symmetry of a digraph $\Gamma (n)$ is proved. The formula for the number of fixed points of $\Gamma (n)$ is established. Moreover, some connection of the length of cycles with the Carmichael $\lambda $-function is presented.
