Magyarországon végzett infrarenalis aortaaneurysma-műtétek eredményei az Érsebészeti Regiszter adatai alapján (2010–2014)

Absztrakt Bevezetés: A Magyar Angiológiai és Érsebészeti Társaság az Érsebészeti Regiszter létrehozása után elhatározta, hogy az egyes beavatkozások eredményeiről rendszeresen beszámol. Célkitűzés: A szerzők 5 év alatt végzett infrarenalis aortaaneurysma-műtétek eredményeinek bemutatását tűzték ki célul. Módszer: A prospektíven rögzített multicentrikus adatokat retrospektíve dolgozták fel. Az Érsebészeti Regiszter 2010. január 1. és 2014. december 31. közötti adatainak statisztikai elemzéséhez Fischer-féle egzakt próbát és esélyhányadost használtak. Eredmények: Az 1435 beavatkozás 16,72%-ára aneurysmaruptura miatt került sor. A műtétek 78,4%-át 5 nagy betegforgalmú intézet végezte. A rupturált aortaaneurysma csoportba tartozó betegek életkora 71,77±9,82 (átlag±SD) év, a perioperatív mortalitás 33,75%, a nem rupturált aortaaneurysma csoport átlagéletkora 69,50±8,46 év, a perioperatív mortalitás 3,51% volt. Endovascularis beavatkozásoknál mindkét csoportban szignifikánsan kisebb volt a halálozás (rupturált: p<0,05, OR = 0,11; nem rupturált: p<0,05, OR = 0,26), illetve az ápolási időszak (rupturált: p<0,05, OR = 4,55; nem rupturált: p<0,001, OR = 4,27) a nyitott műtétekhez képest. Nagy betegforgalmú intézetekben mindkét csoportban szignifikánsan kisebb volt a halálozás (rupturált: p<0,0001, OR = 0,32; nem rupturált: p<0,0001, OR = 0,23) és az ápolási időszak (rupturált: p<0,05, OR = 3,16; nem rupturált: p<0,001, OR = 3,84) a kis betegforgalmú intézetekhez képest. Következtetések: Stentgraft-implantáció és nagy betegforgalmú intézetek esetében szignifikánsan alacsonyabb a perioperatív mortalitás és a posztoperatív ápolási napok száma. Orv. Hetil., 2015, 156(49), 1991–2002

Screening of bat faeces for arthropod-borne apicomplexan protozoa: Babesia canis and Besnoitia besnoiti-like sequences from Chiroptera

Background : 45 Microbats (Chiroptera: Microchiropte ra) are among the most eco - epidemiologically important 46 mammals, owing to their presence in human settlements and ani mal keeping facilities . 47 Roosting of bats in buildings may bring pathogens of veterinary - medical importance into the 48 environment of domestic animals and humans. In this context bats have long been studied as 49 carriers of various pathogen groups. However, despite their close association with arthropods 50 (both in their f oo d and as their ectoparasites), only a few molecular surveys have been 51 publish ed on their role as carriers of vector - borne protozoa. The aim of the present study was 52 to compensate for this scarcity of information. 53 Findings : 54 Altogether 221 (mostly individual) bat faecal samples were collected in Hungary and the 55 Netherlands. The DNA w as extracted , and analysed with PCR and sequencing for the 56 presence of arthropod - borne apicomplexan protozoa. Babesia canis canis (with 99 - 100% 57 homology) was identified in five samples, all from Hungary. Because it was excluded with an 58 Ixodidae - specific PC R that the relevant bats consumed ticks, these sequences derive either 59 from insect carriers of Ba. canis , or from the infection of bats. In one bat faecal sample from 60 the Netherlands a sequence having the highest (99%) homology to Besnoitia besnoiti was 61 am plified. 62 Conclusions : 63 The se findings suggest that some aspects of the epidemiology of canine babesiosis are 64 underestimated or unknown, i.e. the potential role of insect - borne mechanical transmission 65 and/or the susceptibility of bats to Ba. canis . In addit ion, b ats need to be added to future 66 studies in the quest for the final host of Be. besnoiti

Trends in major lower limb amputations related to peripheral arterial disease in Hungary : A nationwide study (2004-2012)

ObjectivesTo assess the trends of peripheral arterial disease associated major lower limb amputation in Hungary over a 9 year period (2004–2012) in the whole Hungarian population.MethodsThis was a retrospective cohort study employing administrative health care data. Major amputations were identified in the entire Hungarian population during a 9 year period (2004–2012) using the health care administrative data. Direct standardization was used to eliminate the potential bias induced by the different age and sex structure of the compared populations. For external direct standardization, the ESP 2013 was chosen as reference.Results76,798 lower limb amputations were performed. The number of major amputations was 38,200; these procedures affected 32,084 patients. According to case detection, 50.4% of the amputees were diabetic. The overall primary amputation rate was 71.5%. The annual crude and age adjusted major amputation rates exhibited no significant long-term pattern over the observation period. The major lower limb amputation incidence for the overall period was 42.3/105 in the total population and 317.9/105 in diabetic population.ConclusionAccording to this whole population based study from Hungary, the incidence of lower limb major amputation is high with no change over the past 9 years. An explanation for this remains to be determined, as the traditional risk factors in Hungary do not account for it. The characteristics of major amputation (the rate of primary amputation, the ratio of below to above knee amputation and the age of the affected population) underline the importance of screening, early detection, improved vascular care and an optimal revascularization policy. Standardization and validation of amputation detection methods and reporting is essential

Vibrational spectra of C60C8H8 and C70C8H8 in the rotor-stator and polymer phases

C60-C8H8 and C70-C8H8 are prototypes of rotor-stator cocrystals. We present infrared and Raman spectra of these materials and show how the rotor-stator nature is reflected in their vibrational properties. We measured the vibrational spectra of the polymer phases poly(C60C8H8) and poly(C70C8H8) resulting from a solid state reaction occurring on heating. Based on the spectra we propose a connection pattern for the fullerene in poly(C60C8H8), where the symmetry of the C60 is D2h. On illuminating the C60-C8H8 cocrystal with green or blue light a photochemical reaction was observed leading to a similar product to that of the thermal polymerization.Comment: 26 pages, 8 figures, to appear in Journal of Physical Chemistry B 2nd version: minor changes in wording, accepted version by journa

Evaluation of Colour Versions of Wild Sage (Salvia nemorosa L.)

In the continental weather zone, more and more frequently occurring extreme conditions require continuous renewal of the market which generates constant challenge for the ornamental plant breeders. Most of the traditionally used decorative ornamental plants are sensitive to these extreme conditions. In 2001, Department of Plant Biotechnology, Debrecen University initiated an interdisciplinary breeding program in collaborations with Zoltan Kovats (he dealt with hungarian drought-tolerant plant species) to produce new or reintroduce forgotten drought-tolerant ornamental species into public parks and roadsides. From ~900 species of Salvia genus, Salvia nemorosa L. has been known as a medical plant, however, because of its high adaptation ability and decorative nature it is a highly recommended ornamental plant as well. Salvia nemorosa L. has a low maintenance, extremely droughttolerant, fast growing plant, generates proper cover, and highly competing weeds on roadsides. Nowadays, 50-60 varieties are available; however this number could be increased by new hybrids. Great morphological and colour variation could be seen within the species, from different white to deep violet. The main goal of this research is the production of elite lines with wide colour and morphological variation in wild sage. We have already obtained 25 different clones for further investigation without eliminating the original plants generating an in vitro gene bank as it has been done by Italian breeders

The Medicago truncatula Vacuolar iron Transporter-Like proteins VTL4 and VTL8 deliver iron to symbiotic bacteria at different stages of the infection process

The symbiotic relationship between legumes and rhizobium bacteria in root nodules has a high demand for iron, and questions remain regarding which transporters are involved. Here, we characterize two nodule-specific Vacuolar iron Transporter-Like (VTL) proteins in Medicago truncatula. Localization of fluorescent fusion proteins and mutant studies were carried out to correlate with existing RNA-seq data showing differential expression of VTL4 and VTL8 during early and late infection, respectively. The vtl4 insertion lines showed decreased nitrogen fixation capacity associated with more immature nodules and less elongated bacteroids. A mutant line lacking the tandemly-arranged VTL4-VTL8 genes, named 13U, was unable to develop functional nodules and failed to fix nitrogen, which was almost fully restored by expression of VTL8 alone. Using a newly developed lux reporter to monitor iron status of the bacteroids, a moderate decrease in luminescence signal was observed invtl4mutant nodules and a strong decrease in 13U nodules. Iron transport capability of VTL4 and VTL8 was shown by yeast complementation. These data indicate that VTL8, the closest homologue of SEN1 in Lotus japonicus, is the main route for delivering iron to symbiotic rhizobia. We propose that a failure in iron protein maturation leads to early senescence of the bacteroids

ACE and ACTN3 genes polymorphisms among female Hungarian athletes in the aspect of sport disciplines

The aim of the study was to determine the importance of two sport-associated gene polymorphisms, alpha-actinin-3 R577X (ACTN3) and angiotensin-converting enzyme I/D (ACE), among Hungarian athletes in different sports. The examination was carried out only on women (n = 100). Sport-specific groups were formed in order to guarantee the most homogeneous clusters. Human genomic DNA was isolated from blood, and genotyping was performed by polymerase chain reaction. To measure the differences between the participating groups, Chi-squared test was performed using Statistica 9.0 for Windows® (significance level: p 0.05) were compared. A similarity was detectable in the I allele frequencies of the water polo (61.11%) and kayaking/rowing (56.67%) groups. The ACTN3 R/X polymorphism showed no differences in comparison with the sport groups. R allele frequencies were higher in every group compared to the X allele. The potential significance of the ACE I allele in sports of an aerobic nature was not clearly confirmed among Hungarian athletes
