The software can work with the real database and the virtual traffic of the intersection simulated by VISSIM. Therefore the dissimiliarity between the real and simulated traffic can be seen. Some interim results will be useful in further research: The perception and decision process of stopping at red light has been described by the descriptive language used in simulation (UML), and the decisions influenced by human parameter and its output have been defined. The human error in selected traffic situations was determined based on available data, and the aggressive and normal driver behaviour was described by the given definition. Theories of priori and apriori probability of human error adapted in different engineering fields were analyzed, and the method which could be applied in traffic engineering was selected

A fogpĂłtláskĂ©szĂtĂ©s szempontjai biszfoszfonáttal kezelt idĹ‘s páciens esetĂ©n
Absztrakt:
Napjainkra egyre elterjedtebbek a csont átépülésére, vérkeringésére és
homeosztázisára ható gyógyszerek, amelyek szerepe megkérdőjelezhetetlen számos
súlyos betegség terápiájában. Ilyenek például a biszfoszfonátok és más
antireszorptĂv Ă©s antiangiogenikus terápiás szerek. Pontos anamnĂ©zisfelvĂ©telt
követően minden fogorvosi praxisban detektálható, hogy az ezeket a gyógyszereket
szedő páciensek száma emelkedik. Célunk egy idős nőbeteg komplex fogászati
kezelĂ©sĂ©n bemutatva megvilágosĂtani azokat a prevenciĂłs lĂ©pĂ©seket, amelyek
betartásával minimalizálható a rizikócsoportba tartozó betegekben a gyógyszer
indukálta osteonecrosis kialakulásának valĂłszĂnűsĂ©ge. A szájsebĂ©szeti,
konzerváló fogászati és protetikai ellátás szinkronizálása kitüntetett szereppel
bĂr egy idĹ‘s, sok háttĂ©rbetegsĂ©ggel rendelkezĹ‘ páciens esetĂ©n. CĂ©lunk továbbá
felhĂvni a társszakmákban dolgozĂł kollĂ©gák figyelmĂ©t a beavatkozások
idĹ‘zĂtĂ©sĂ©nek jelentĹ‘sĂ©gĂ©re. Az állcsontnecrosis megelĹ‘zĂ©sĂ©nek alapja a
gyógyszerszedés előtti teljes körű fogászati szanálás. Amennyiben azonban a
páciens már szedi a csontmetabolizmusra hatĂł Ă©s mucotoxicus kĂ©szĂtmĂ©nyt,
megfelelő felkészültség és gondosság mellett lehet esély a súlyos, az
életminőséget komolyan befolyásoló és rossz gyógyulási hajlamot mutató
szövődmények megelőzésére. Orv Hetil. 2018; 159(48): 2031–2036.

Abstract:
Recently, drugs targeting the remodelling, vascular circulation and homeostasis
of bone are frequently applied with an unquestionable benefit in the therapy of
numerous severe medical conditions. Besides bisphosphonates, other
antiresorptive and antiangiogenic drugs are also used, however, limited
publications are focusing on data of their results. Increasing number of
patients arrives the mentioned medication is increasing in the daily dental
practice, especially when accurate anamnesis is taken. Our aim is to highlight
the preventive considerations that help minimize the occurence of
medication-related osteonecrosis of the jaw by presentating a complex dental
rehabilitation of a patient at risk. The synchronization of dental surgery,
conservative and prosthodontic treatment is essential in the case of an elderly
patient having many concomitant disorders. Our aim is also to draw the attention
of our colleagues working on different medical fields to the timing of dental
procedures. The best and simplest way to prevent jaw necrosis is to achieve good
oral health and hygiene before the introduction of antiresorptive therapy. If,
however, our patient is already taking this medication, we still have a chance
to prevent the appearance of this devastating condition by following the
preventive measures. The medication-related necrosis of the jaw is a severe
condition leading to a decreased life quality and having a reduced healing
expectancy. Orv Hetil. 2018; 159(48): 2031–2036
A gyógyszer által indukált állcsontnecrosis-kockázat mértékének meghatározása az általános fogorvosi gyakorlatban
Absztrakt:
A gyĂłgyszer indukálta osteonecrosis antireszorptĂv terápia szövĹ‘dmĂ©nyekĂ©nt lĂ©phet
fel, kezelĂ©se komoly kihĂvást jelent. A betegsĂ©g 2003. Ă©vi leĂrását követĹ‘en a
gyógyszer indukálta osteonecrosis kialakulásában szerepet játszó szisztémás és
lokális rizikófaktorokat gyűjtöttük össze. A rizikófaktorokat a
PubMed-adatbázisban az 1998 és 2018 közötti időszakban megjelent irodalmi
kutatások alapján rendszereztük. A kockázattal élő pácienseink három csoportja:
antireszorptĂv terápiát mĂ©g nem megkezdettek, már antireszorptĂv terápiában
részesülők, manifeszt osteonecrosisban szenvedők. A fogorvos feladata a
rizikĂłfaktorok felmĂ©rĂ©se, ennek megfelelĹ‘ kezelĂ©si terv felállĂtása, a
kontrollvizsgálatok gyakoriságának megszabása. Az antireszorptĂv terápiák közĂĽl
az onkológiai indikációval kapott intravénás kezelés jelenti a legnagyobb
kockázatot. További szisztĂ©más rizikĂłfaktorok: járulĂ©kos terápia, kĂsĂ©rĹ‘
betegség, életmód, személyi tényezők. A lokális rizikófaktorok a következők:
dentoalveolaris sebészi beavatkozás, periapicalis és parodontalis gyulladások,
rosszul illeszkedő kivehető fogpótlások, anatómiai eltérések. A rizikófaktorok
halmozĂłdása határozza meg a necrosis kialakulásának valĂłszĂnűsĂ©gĂ©t. Az
osteonecrosis kialakulásának akkor a legkisebb a valĂłszĂnűsĂ©ge, ha a beteg a
biszfoszfonátterápiát szanált fogazati statusszal kezdi meg. Orv Hetil. 2019;

Abstract:
Medication-related osteonecrosis of the jaw may appear as adverse effect in
antiresorptive therapy. Its successful treatment is challenging. We aimed to
gather the systemic and local factors playing a role in etiology, published
after its recognition. Risk factors were collected from the PubMed database
1998–2018. The three main groups of risk patients are: patients starting,
patients having antiresorptive therapy, osteonecrosis diagnosed patients. The
dentist must recognize risk factors, determine appropriate treatment plan and
frequency of check-ups. Oncological disease treated intravenously means the
greatest risk. Further systemic risk factors are: supportive therapies,
concomitant disease, way of life, individual factors. Local risk factors may be:
dentoalveolar surgery, periapical and periodontal inflammation, ill-fitting
denture, presence of some anatomical structures. The accumulation of risk
factors determines the probability of the manifestation of osteonecrosis. The
most favorable case is patient starting antiresorptive therapy with a dental
status needing no treatment. Orv hetil. 2019; 160(7): 243–251
Preparation and characterization of site-specific dechlorinating microbial inocula capable of complete dechlorination enriched in anaerobic microcosms amended with clay mineral
Short-chain halogenated aliphatic hydrocarbons (e.g. perchloroethene, trichloroethene) are among the most toxic environmental pollutants. Perchloroethene and trichloroethene can be dechlorinated to non-toxic ethene through reductive dechlorination by Dehalococcoides sp. Bioaugmentation, applying cultures containing organohalide-respiring microorganisms, is a possible technique to remediate sites contaminated with chlorinated ethenes. Application of site specific inocula is an efficient alternative solution. Our aim was to develop site specific dechlorinating microbial inocula by enriching microbial consortia from groundwater contaminated with trichloroethene using microcosm experiments containing clay mineral as solid phase. Our main goal was to develop fast and reliable method to produce large amount (100 L) of bioactive agent with anaerobic fermentation technology. Polyphasic approach has been applied to monitor the effectiveness of dechlorination during the transfer process from bench-scale (500 mL) to industrial-scale (100 L). Gas chromatography measurement and T-RFLP (Terminal Restriction Fragment Length Polymorphism) revealed that the serial subculture of the enrichments shortened the time-course of the complete dechlorination of trichloroethene to ethene and altered the composition of bacterial communities. Complete dechlorination was observed in enrichments with significant abundance of Dehalococcoides sp. cultivated at 8 °C. Consortia incubated in fermenters at 18 °C accelerated the conversion of TCE to ethene by 7–14 days. Members of the enrichments belong to the phyla Bacteroidetes, Chloroflexi, Proteobacteria and Firmicutes. According to the operational taxonomic units, main differences between the composition of the enrichment incubated at 8 °C and 18 °C occurred with relative abundance of acetogenic and fermentative species. In addition to the temperature, the site-specific origin of the microbial communities and the solid phase applied during the fermentation technique contributed to the development of a unique microbial composition.ISSN:0959-3993ISSN:1573-097

Janus Kinase Inhibitors Improve Disease Activity and Patient-Reported Outcomes in Rheumatoid Arthritis: A Systematic Review and Meta-Analysis of 24,135 Patients
Pain, fatigue, and physical activity are major determinants of life quality in rheumatoid arthritis (RA). Janus kinase (JAK) inhibitors have emerged as effective medications in RA and have been reported to exert direct analgesic effect in addition to reducing joint inflammation. This analysis aims to give an extensive summary of JAK inhibitors especially focusing on pain and patient reported outcomes (PRO). MEDLINE, CENTRAL, Embase, Scopus, and Web of Science databases were searched on the 26 October 2020, and 50 randomized controlled trials including 24,135 adult patients with active RA met the inclusion criteria. JAK inhibitors yielded significantly better results in all 36 outcomes compared to placebo. JAK monotherapy proved to be more effective than methotrexate in 9 out of 11 efficacy outcomes. In comparison to biological disease-modifying antirheumatic drugs, JAK inhibitors show statistical superiority in 13 of the 19 efficacy outcomes. Analgesic effect determined using the visual analogue scale and American College of Rheumatology (ACR) 20/50/70 response rates was significantly greater in the JAK group in all comparisons, and no significant difference regarding safety could be explored. This meta-analysis gives a comprehensive overview of JAK inhibitors and provides evidence for their superiority in improving PROs and disease activity indices in RA
