Cieľ štúdie: Zistiť výhody supraklavikulárnej blokády brachiálneho plexu pri vytváraní artériovenóznych fistúl pre hemodialyzačnú liečbu, porovnanie periférnej nervovej blokády, celkovej anestézie a lokálnej infiltračnej anestézie pri tvorbe artériovenóznych fistúl. Typ štúdie: Prospektívna nerandomizovaná štúdia. Schválená etickou komisiou JLF UK v Martine. Typ pracoviska: Klinické pracovisko univerzitnej nemocnice. Materiál a metóda: Súbor pacientov, ktorým bola vytvorená artériovenózna fistula, bol rozdelený do 3 skupín. Skupina 20 pacientov bola operovaná v periférnej nervovej blokáde, skupina 20 pacientov bola operovaná v lokálnej infiltračnej anestézii a skupina 5 pacientov bola operovaná v celkovej anestézii. Hlavným sledovaným parametrom bola zachovaná funkcia fistuly 24 hodín a 6 týždňov po operácii. Inklúzne kritériá pacientov boli: vek 19–75 rokov, ASA 3–4, hmotnosť 40–120 kg, BMI do 40. Použili sa štatistické metódy: Mannov-Whitneyov U test a exaktný obojstranný test, Shapirov-Wilkov test, Fisherov obojstranný exaktný test, párový Wilcoxonov exaktný obojstranný test. Výsledky: Po 24 hodinách boli funkčné všetky fistuly vytvorené v periférnej nervovej blokáde, 90 % v lokálnej infiltračnej anestézii a 80 % v celkovej anestézii. Nepreukázala sa štatisticky významná závislosť medzi funkčnosťou fistuly a niektorým typom anestézie. Po 6 týždňoch bolo funkčných 80 % fistúl vytvorených v celkovej anestézii alebo periférnej nervovej blokáde a iba 50 % fistúl v lokálnej infiltračnej anestézii. Štatisticky významný rozdiel bol zistený medzi skupinou pacientov operovaných v periférnej nervovej blokáde a lokálnej infiltračnej anestézii, a to v prospech periférnej nervovej blokády (p < 0,05). Záver: Periférna nervová blokáda sa v našej štúdii spájala s lepším prežívaním fistuly oproti lokálnej infiltračnej anestézii. Pri celkovej anestézii bolo prežívanie fistuly porovnateľné ako pri periférnej nervovej blokáde, bola však spojená s vyšším výskytom komplikácií.
Objective: To determine the advantages of supraclavicular blockade of the brachial plexus in the formation of arteriovenous fistulas for hemodialysis treatment. Comparison of peripheral nerve block, general and local infiltration anesthesia in the formation of fistulas. Design: Prospective non-randomized study. Approved by the ethics committee of JLF UK in Martin. Setting: University hospital. Material and methods: Three groups of patients who were created arteriovenous fistula. A group of 20 patients were operated under peripheral nerve block anesthesia, 20 patients were operated under local infiltration anesthesia and 5 patients were operated under general anesthesia. The main monitored parameter was the preserved function of the fistula 24 hours and 6 weeks after the operation. Inclusion criteria: age 19–75 years, ASA 3–4, weight 40–120 kg, BMI up to 40. Statistical methods: Mann-Whitney U test and exact two-tailed test, Shapiro-Wilk test, Fisher's two-tailed exact test, paired Wilcoxon's exact two-tailed test. Results: After 24 hours, all fistulas created under peripheral nerve block anesthesia were functional, 90 % under local infiltration anesthesia and 80 % under general anesthesia. There was no statistically significant dependence between the functionality of the fistula and any type of anesthesia. After 6 weeks, 80 % of fistulas created under general or peripheral nerve block anesthesia and only 50 % of fistulas under local infiltration anesthesia were functional. For peripheral nerve block anesthesia and local infiltration anesthesia, a statistically significant difference was found in favor of peripheral nerve block anesthesia (p < 0.05). Conclusion: Peripheral nerve block anesthesia was associated with better fistula survival compared to local infiltration anesthesia in our study. General anesthesia had fistula survival comparable to peripheral nerve block anesthesia, but was associated with a higher incidence of complications.

OBJECTIVES: The default mode resting state network (DMRSN) constitutes a circuit which is active in conditions when the subject is at rest. We tested the hypothesis that its function will be altered during unconsciousness. METHODS: Changes in the mean squared coherences in five conventional frequency bands (delta to gamma) in DMRSN during general anaesthesia (GA) were investigated in 39 patients. They were compared with the normal EEG of 86 alert subjects, severely abnormal EEG of 112 patients with dementia and/or encephalopathy, and the mathematical model of brain death. RESULTS: Anaesthetised patients showed significant decrease in the gamma coherence in the posterior area of the DMRSN compared to both the control group and the patients with dementia and/or encephalopathy. Among the anaesthetized patients 21 had a clear burst suppression pattern with prolonged epochs of suppression in EEG. In suppressed EEG segment the differences between the connections of the anterior to posterior parts and connections between the posterior parts of the DMRSN were almost lost. However, they still showed highly significant differences in most items when compared with coherences in the mathematical model of brain death. CONCLUSION: The functional connectivity in the DMRSN could be a reliable and robust method for assessing the depth of anaesthesia and maybe also disorders of consciousness in general. The mean squared coherences in the gamma frequency band indicated the highest sensitivity for the depth of unconsciousness. The measure is not dependent on the diffused slowing in dementia or encephalopathy patients as long as they remain in a full consciousness.

The regulation of gene transcription allows yeast cells to respond properly to changing environmental conditions. Several protein complexes take part in this process. They involve RNA polymerase complexes, chromatin remodeling complexes, mediators, general transcription factors and specific transcriptional regulators. Using Saccharomyces cerevisiae as reference, the genomes of six species (Ashbya gossypii, Kluyveromyces lactis, K. waltii, Candida albicans, C. glabrata and Schizosaccharomyces pombe) that are human pathogens or important for the food industry were analyzed for their complement of genes encoding the homologous transcriptional regulators. The number of orthologs identified in a given species correlated with its phylogenetic distance from S. cerevisiae. Many duplicated genes encoding transcriptional regulators in S. cerevisiae and C. glabrata were reduced to one copy in species diverged before the ancestral whole genome duplication. Some transcriptional regulators appear to be specific for S. cerevisiae and probably reflect the physiological differences among species. Phylogenetic analysis and conserved gene order relationships indicate that a similar set of gene families involved in the control of multidrug resistance and oxidative stress response already existed in the common ancestor of the compared fungal species.
