Állami támogatások és gazdasági teljesítmény. Támogatás-túladagolás a magyar gazdaságfejlesztésben? (An overdose of state aid in the Hungarian economy)

Magyarországon az elmúlt évtizedben a vállalatoknak nyújtott állami támogatás GDP-arányosan számolva az európai uniós átlag 2,7-szerese volt. A cikk megvizsgálja, hogy a támogatások hatása megjelenik-e a magyar gazdaság beruházási, foglalkoztatási, jövedelemtermelési teljesítményében és versenyképességében. Arra a következtetésre jut, hogy egyik területen sem jobb a helyzet, mint azokban az országokban, amelyekben lényegesen alacsonyabb a támogatási arány. A mikroszintű elemzések, értékelések sem támasztják alá azt a vélekedést, hogy az állami támogatások érzékelhetően javítják a gazdasági teljesítményt. A források bősége önmagában is okoz hatékonysági problémákat, mert sok program és szervezet versenyez egymással. A rossz (gyengébb hatékonysági követelményeket támasztó) programok kiszorítják a jó programokat. Ha a versenyképességet érdemben befolyásoló tényezők, például a kedvező jogi szabályozási környezet és az üzleti szolgáltatások jól működő piacai nem adottak, akkor ezek hiányát nem ellensúlyozza a támogatások magas szintje. Magyarország az idén indult hétéves programozási időszakban tovább kívánja növelni a vállalatoknak nyújtott állami támogatások mértékét, miközben nincs egyértelmű válasz arra a kérdésre, hogy milyen módon növelhető a támogatási rendszer jelenleg alacsony hatékonysága. _____ State aid given to enterprises as a proportion of Hungary�s GDP has been 2.7 times the EU average over the past decade. The article examines whether any impact of this high level of state aid can be discerned in investment, employment, income- generation performance, or competitiveness of the Hungarian economy. It seems that in none of these areas is the situation better than in countries that have a markedly lower rate of state aid. Micro-level analyses and evaluations do not support the belief that state aid appreciably improves economic performance. A wealth of resources on its own can cause problems with efficiency, as many programs and organizations compete with each other. Bad (less demanding) programs nudge out the good ones. If the factors significantly determining competitiveness, including a favourable legal and regulatory environment and well-functioning markets of business services, are not in place, a high level of state aid cannot be a proxy for them. In the seven-year programming period beginning this year, Hungary plans to further increase the amount of state aid to enterprises, while there is no clear answer as to how to improve the currently poor efficiency of the state aid system.

Characteristics of hospital-treated intentional drug overdose in Ireland and Northern Ireland

OBJECTIVES This study compared the profile of intentional drug overdoses (IDOs) presenting to emergency departments in Ireland and in the Western Trust Area of Northern Ireland between 2007 and 2012. Specifically the study aimed to compare characteristics of the patients involved, to explore the factors associated with repeated IDO and to report the prescription rates of common drug types in the population. METHODS We utilised data from two comparable registries which monitor the incidence of hospital-treated self-harm, recording data from deliberate self-harm presentations involving an IDO to all hospital emergency departments for the period 1 January 2007 to 31 December 2012. RESULTS Between 2007 and 2012 the registries recorded 56,494 self-harm presentations involving an IDO. The study showed that hospital-treated IDO was almost twice as common in Northern Ireland than in Ireland (278 vs 156/100,000, respectively). CONCLUSIONS Despite the overall difference in the rates of IDO, the profile of such presentations was remarkably similar in both countries. Minor tranquillisers were the drugs most commonly involved in IDOs. National campaigns are required to address the availability and misuse of minor tranquillisers, both prescribed and non-prescribed.

Use of analgesics in intentional drug overdose presentations to hospital before and after the withdrawal of distalgesic from the Irish market

BACKGROUND: Distalgesic, the prescription-only analgesic compound of paracetamol (325 mg) and dextropropoxyphene (32.5 mg) known as co-proxamol in the UK, was withdrawn from the Irish market as of January 2006. This study aimed to evaluate the impact of the withdrawal of distalgesic in terms of intentional drug overdose (IDO) presentations to hospital emergency departments (EDs) nationally. METHODS: A total of 42,849 IDO presentations to 37 of the 40 hospitals EDs operating in Ireland in 2003-2008 were recorded according to standardised procedures. Data on sales of paracetamol-containing drugs to retail pharmacies for the period 1998-2008 were obtained from IMS Health. RESULTS: The withdrawal of distalgesic from the Irish market resulted in an immediate reduction in sales to retail pharmacies from 40 million tablets in 2005 to 500,000 tablets in 2006 while there was a 48% increase in sales of other prescription compound analgesics. The rate of IDO presentations to hospital involving distalgesic in 2006- 2008 was 84% lower than in the three years before it was withdrawn (10.0 per 100,000). There was a 44% increase in the rate of IDO presentations involving other prescription compound analgesics but the magnitude of this rate increase was five times smaller than the magnitude of the decrease in distalgesic-related IDO presentations. There was a decreasing trend in the rate of presentations involving any paracetamol-containing drug that began in the years before the distalgesic withdrawal. CONCLUSIONS: The withdrawal of distalgesic has had positive benefits in terms of IDO presentations to hospital in Ireland and provides evidence supporting the restriction of availability of means as a prevention strategy for suicidal behaviour.

Nonfatal heroin overdoses in Queensland, Australia : an analysis of ambulance data

In the past decade, the utilization of ambulance data to inform the prevalence of nonfatal heroin overdose has increased. These data can assist public health policymakers, law enforcement agencies, and health providers in planning and allocating resources. This study examined the 672 ambulance attendances at nonfatal heroin overdoses in Queensland, Australia, in 2000. Gender distribution showed a typical 70/30 male-to-female ratio. An equal number of persons with nonfatal heroin overdose were between 15 and 24 years of age and 25 and 34 years of age. Police were present in only 1 of 6 cases, and 28.1% of patients reported using drugs alone. Ambulance data are proving to be a valuable population-based resource for describing the incidence and characteristics of nonfatal heroin overdose episodes. Future studies could focus on the differences between nonfatal heroin overdose and fatal heroin overdose samples.

If you don’t know, you can’t help: A practical guide for alcohol and other drug screening in psychological services

Alcohol is implicated in over 60 diseases and injuries and accounted for 6.2 per cent of all male deaths globally in 2004 (WHO, 2011). Alcohol and other drug (AOD) abuse causes significant individual, family and social harms at all age levels and across all socioeconomic groups. These may result from intoxication (e.g., overdose, vulnerability to physical injury/trauma or death, consequences of impulsive behaviour, aggression and driving under the influence) and longer-term consequences (e.g., alcohol or drug-related brain injury, cardiovascular and liver diseases, blood borne viruses e.g., Chikritzhs et al., 2003, Roxburgh et al., 2013). Mental health problems may be triggered or exacerbated, and family breakdown, poor self-esteem, legal issues and lack of community engagement may also be evident. Despite the prevalence of substance use disorders and evident consequences for the individual, family and wider community, it would seem that health professionals, including psychologists, are reluctant to ask about substance use.

Bioavailability aspects of hydrophobic contaminant degradation in soils

This thesis concentrates on bioavailability of organic soil contaminants in the context of bioremediation of soil contaminated with volatile or non-volatile hydrophobic pollutants. Bioavailability and biodegradation was studied from four viewpoints: (i) Improvement of bioavailability and biodegradation of volatile hydrocarbons in contained bioremediation systems at laboratory - and pilot-scale. (ii) Improvement of bioavailability of non-volatile, hydrophobic compounds in such systems. (iii) Biodegradation of a non-volatile hydrophobic compound in soil organic matter in microcosms. (iiii) Bioavailability of nitrogen in an open, full-scale bioremediation system. It was demonstrated that volatility of organic compounds can be controlled by amending the soil with adsorbents. The sorbed hydrocarbons were shown to be available to soil microbiota. As the result, biodegradation of the volatile hydrocarbons was greatly favored at the expense of volatilization. PAH compounds were shown to be mobilized and their bioavailability improved by a hydrophobic, non-toxic additive, vegetable oil. Bioavailability of the PAHs was recorded as an increased toxicity of the soil. In spite of the increased bioavailability, biodegradation of the PAHs decreased. In microcosms simulating boreal forest organic surface soil, PAH-compound (pyrene) was shown to be removed from soil biologically. Therefore hydrophobicity of the substrate does not necessarily mean low availability and biodegradation in organic soil. Finally, in this thesis it was demonstrated that an unsuitable source of nitrogen or its overdose resulted in wasteful spending of this nutrient and even harmful effects on soil microbes. Such events may inhibit rather than promote the bioremediation process in soil.

Farnesyltransferase Inhibitors Reduce Ras Activation and Ameliorate Acetaminophen-Induced Liver Injury in Mice

Hepatotoxicity due to overdose of the analgesic and antipyretic acetaminophen (A-PAIP) is a major cause of liver failure in adults. To better understand the contributions of different signaling pathways, the expression and role of Ras activation was evaluated after oral dosing of mice with APAP (400-500 mg/kg). Ras-guanosine triphosphate (GTP) is induced early and in an oxidative stress-dependent manner. The functional role of Ras activation was studied by a single intraperitoneal injection of the neutral sphingomyelinase and farnesyltransferase inhibitor (FTI) manumycin A (I mg/kg), which lowers induction of Ras-GTP and serum amounts of alanine aminotransferase (ALT). APAP dosing decreases hepatic glutathione amounts, which are not affected by manumycin A treatment. However, APAP-induced activation of c-Jun N-terminal kinase, which plays an important role, is reduced by manumycin A. Also, APAP-induced mitochondrial reactive oxygen species are reduced by manumycin A at a later time point during liver injury. Importantly, the induction of genes involved in the inflammatory response (including iNos, gp91phox, and Fasl) and serum amounts of proinflammatory cytokines interferon-gamma (IFN gamma) and tumor necrosis factor alpha, which increase greatly with APAP challenge, are suppressed with manumycin A. The FTI ctivity of manumycin A is most likely involved in reducing APAP-induced liver injury, because a specific neutral sphingomyelinase inhibitor, GW4869 (I mg/kg), did not show any hepatoprotective effect. Notably, a structurally distinct FTI, gliotoxin (I mg/kg), also inhibits Ras activation and reduces serum amounts of ALT and IFN-gamma after APAP dosing. Finally, histological analysis confirmed the hepatoprotective effect f manumycin A and gliotoxin during APAP-induced liver damage. Conclusion: This study identifies a key role for Ras activation and demonstrates the therapeutic efficacy of FTIs during APAP-induced liver injury.

Ketoprofeenin biologinen käytettävyys ja farmakokinetiikka sioilla eri antotavoilla ja ketoprofeeniyliannoksen farmakokinetiikka ja vaikutus munuaisiin lampailla

Ketoprofeeni on yleisesti käytetty ei-steroidinen tulehduskipulääke (NSAID) lampaiden ja sikojen kivunlievityksessä. Tietoa ketoprofeenin oikeista annosmääristä eri eläinlajeilla on saatavilla rajallisesti. Oikeaa lääkeainemäärää ei voida luotettavasti ekstrapoloida toisten eläinlajien tai ihmisten perusteella. Epäillyissä tulehduskipulääkemyrkytyksissä ongelmana on tietää, oliko eläimen saama lääkeannos toksinen. Lampailla tehdyn tutkimuksen tavoitteena oli selvittää, muuttuuko ketoprofeenin kinetiikka kymmenkertaisella yliannoksella, tutkia yliannoksen vaikutusta munuaisiin ja löytää yksinkertainen tapa diagnosoida yliannos virtsasta. Sioilla tehdyn tutkimuksen tavoitteena oli selvittää ketoprofeenin biologista käytettävyyttä ja ketoprofeenin farmakokinetiikkaa sioilla intravaskulaarisella, intramuskulaarisella ja peroraalisella annolla. Keskeiset tutkimuksessa määritettävät muuttujat olivat AUC0-_, Cmax ja tmax. Hyötyosuus laskettiin i.v. -annon perusteella. Kuudelle lampaalle annettiin 30 mg/kg i.v. -ketoprofeenia. Ketoprofeenin pitoisuuksia seurattiin 24 tunnin ajan plasmanäytteillä, joiden perusteella määritettiin farmakokineettiset parametrit. Veri- ja virtsanäytteistä tutkittiin muun muassa mahdollisesta munuaisvauriosta kertovia entsyymejä. 24 tunnin kuluttua lääkkeenannosta lampaat lopetettiin ja munuaiset tutkittiin histologisesti. Tutkittaville kahdeksalle sialle annosteltiin 3 mg/kg intravaskulaarista, intramuskulaarista ja oraalista ketoprofeenia sekä 6 mg/kg oraalista ketoprofeenia. Tutkimus suoritettiin satunnaistettuna vaihtovuorotutkimuksena. Ketoprofeenin pitoisuuksia seurattiin plasmanäytteillä 48 tunnin ajan lääkkeenannosta ja kaikille antotavoille laskettiin farmakokineettiset parametrit. Lisäksi tutkittiin valmisteiden biologinen samanarvoisuus. Molempien tutkimusten in vivo -kokeet suoritettiin Eläinlääketieteellisessä tiedekunnassa. Samoin munuaisten histologinen tutkimus ja virtsasta ja verestä tehdyt määritykset, lukuun ottamatta ketoprofeeninpitoisuuden analysointia. Plasman ketoprofeenipitoisuus analysoitiin korkean erotuskyvyn nestekromatografialla (HPLC). Ketoprofeenimääritykset ja farmakokineettinen analyysi suoritettiin Farmasian tiedekunnassa. Lampaiden kymmenkertainen ketoprofeeniyliannos oli toksinen. Seerumin urea- ja kreatiniinipitoisuus nousivat ja histologisissa näytteissä näkyi akuutti munuaistiehyen vaurio. Useiden entsyymien pitoisuus nousi virtsassa. Selvimmin ja nopeimmin nousi virtsan laktaattidehydrogenaasipitoisuus, jonka määrittäminen vaikuttaa potentiaaliselta tavalta diagnosoida ketoprofeenin toksinen annos. Ketoprofeenin eliminaation puoliintumisaika toksisella annoksella oli samaa suuruusluokkaa kuin aiemmissa tutkimuksissa terapeuttisella annoksella, joten yliannos ei muuttanut ketoprofeenin kinetiikkaa. AUC- ja Cmax -arvot olivat suhteessa suurempia kuin terapeuttisella annoksella, joten tutkimuksen perusteella kyseiset arvot eivät nousseet lineaarisesti annoksen noustessa toksiseksi. Sioille annetut ketoprofeenivalmisteet eivät olleet biologisesti samanarvoisia keskenään. Hyötyosuus oli erittäin hyvä kaikilla antotavoilla. tmax oli kaikilla antotavoilla hieman yli tunnin kuluttua lääkkeenannosta. Oraalisen 3 mg/kg -annoksen Cmax oli 5,1 mg/l ja AUC 32 mg l-1 h ja intramuskulaarisen vastaavat arvot olivat 7,6 mg/l ja 37 mg l-1 h. Oraalisen ketoprofeenin annostasojen AUC- ja Cmax -arvot korreloivat keskenään, joten ketoprofeenin kinetiikka oli lineaarista. Intravaskulaarisen ja oraalisen annon puoliintumisajoissa oli tilastollisesti merkitsevä ero. Ketoprofeenin jakautumistilavuudessa ja puhdistumassa ei ollut tilastollisesti merkitsevää eroa eri antotapojen välillä.

A Stochastic Chemical Dynamic Approach to Correlate Autoimmunity and Optimal Vitamin-D Range

Motivated by several recent experimental observations that vitamin-D could interact with antigen presenting cells (APCs) and T-lymphocyte cells (T-cells) to promote and to regulate different stages of immune response, we developed a coarse grained but general kinetic model in an attempt to capture the role of vitamin-D in immunomodulatory responses. Our kinetic model, developed using the ideas of chemical network theory, leads to a system of nine coupled equations that we solve both by direct and by stochastic (Gillespie) methods. Both the analyses consistently provide detail information on the dependence of immune response to the variation of critical rate parameters. We find that although vitamin-D plays a negligible role in the initial immune response, it exerts a profound influence in the long term, especially in helping the system to achieve a new, stable steady state. The study explores the role of vitamin-D in preserving an observed bistability in the phase diagram (spanned by system parameters) of immune regulation, thus allowing the response to tolerate a wide range of pathogenic stimulation which could help in resisting autoimmune diseases. We also study how vitamin-D affects the time dependent population of dendritic cells that connect between innate and adaptive immune responses. Variations in dose dependent response of anti-inflammatory and pro-inflammatory T-cell populations to vitamin-D correlate well with recent experimental results. Our kinetic model allows for an estimation of the range of optimum level of vitamin-D required for smooth functioning of the immune system and for control of both hyper-regulation and inflammation. Most importantly, the present study reveals that an overdose or toxic level of vitamin-D or any steroid analogue could give rise to too large a tolerant response, leading to an inefficacy in adaptive immune function.

Regeneração do autoimplante esplênico em ratos: avaliação morfofuncional e imuno-histoquímica

Diante da importância do baço, deve-se tentar a sua preservação sempre que possível e, nas situações em que a esplenectomia total é inevitável, a única alternativa para a preservação de sua função parece ser a realização do autoimplante esplênico. Neste contexto, o objetivo do presente trabalho foi analisar o desenvolvimento da regeneração morfológica do tecido autoimplantado, sob microscopia de luz e por imunomarcação, e avaliar a regeneração funcional, por meio da depuração dos corpúsculos de Howell-Jolly, em ratos submetidos a esplenectomia total combinada com autoimplante esplênico. Foram utilizados 112 ratos Wistar albinos machos adultos, distribuídos aleatoriamente em 16 grupos. Semanalmente, durante 16 semanas, os sete animais de cada grupo foram submetidos a coleta sanguínea, sendo preparadas lâminas para avaliação da presença de corpúsculos de Howell-Jolly (avaliação funcional), que estiveram presentes durante as 15 primeiras semanas, sendo que, a partir da oitava semana, houve uma diminuição significativa, mas somente não foram mais identificados na 16 semana. Em seguida à coleta sanguínea, os animais correspondentes a cada semana foram mortos por sobredose anestésica e submetidos a relaparotomia para retirada do tecido esplênico autoimplantado regenerado. Posteriormente, esse tecido regenerado foi analisado sob microscopia de luz, onde, sob coloração de hematoxilina-eosina, observou-se regeneração morfológica completa do tecido autoimplantado a partir da oitava semana, sendo encontrado um tecido morfologicamente idêntico ao baço normal. Com a técnica de resorcina-fucsina de Weigert, identificaram-se fibras do sistema elástico, demonstrando elastogênese intensa no processo de regeneração do tecido esplênico autoimplantado. Na imunomarcação com antígeno de proliferação celular nuclear (PCNA), observou-se proliferação celular, evidenciando uma expressão gradativa das células a partir da 2 semana, sendo que, nas 9 e 10 semanas, observou-se aumento significativo na imunodensidade, quando comparadas às demais, o que não ocorreu com a técnica para caspase-3, onde a apoptose mais intensa ocorreu nas primeiras semanas. Nossos resultados mostram que, com oito semanas, existe regeneração morfológica do autoimplante esplênico, assemelhando-se a um baço normal, no mesmo momento em que parece iniciar-se a sua regeneração funcional.

Avaliação estereológica glomerular em rins de ratos após isquemia-reperfusão por clampeamento arteriovenoso e arterial

A técnica de isquemia-reperfusão tem sido utilizada em cirurgias conservadoras do rim como a nefrectomia parcial e em transplantes renais. Para se realizar a isquemia pode-se fazer o bloqueio do fluxo sanguíneo da artéria renal ou o bloqueio simultâneo da artéria e da veia renal. O evento isquêmico acarreta em dano celular ao rim principalmente pelo estresse oxidativo local e a liberação de radicais livres assim como o aumento da resposta inflamatória. Diversos autores verificaram lesão renal após a isquemia-reperfusão, porém, apenas testes funcionais foram realizados até o momento. Os autores que tentaram avaliar a lesão morfológica do rim apenas fizeram a quantificação de escores subjetivos. O nosso objetivo é avaliar por quantificação estereológica o dano causado pela isquemia-reperfusão comparando o clampeamento somente arterial com o clampeamento arteriovenoso. Utilizamos 24 ratos wistar, machos, de quatro meses de idade. Os animais foram divididos em três grupos: o grupo Sham (n=8), o grupo de clampeamento somente da artéria renal (n=8) e o grupo de clampeamento simultâneo da artéria e da veia renal (n=8). Os animais foram submetidos a laparotomia mediana. Os animais do grupo Sham permaneceram os 60 minutos anestesiados mas sem obstrução do fluxo sanguíneo de seus vasos renais. Os animais do grupo de clampeamento arterial foram submetidos à clampeamento de sua arterial renal esquerda por 60 minutos e os animais do grupo de clampeamento arterial e venoso tiveram seus vasos renais esquerdos clampeados simultaneamente e em bloco pelo mesmo tempo. Após os 60 minutos os animais foram suturados e mantidos por 30 dias em caixas próprias sendo mortos por sobredose anestésica após decorrido esse tempo. Os rins foram coletados e mantidos em solução de formalina tamponada e posteriormente processados para análise histológica e estereológica. Foram analisados a densidade volumétrica (Vv) dos glomérulos, o número de glomérulos/mm3(Nv) e o volume glomerular médio (VGM). A Vv e Nv se encontrou reduzida nos rins esquerdos submetidos à isquemia mas foi somente significativa nos animais do grupo de clampeamento arterial e venoso. Mesmo usando o rato como modelo animal experimental, a partir de nossos resultados recomendamos o uso do clampeamento somente arterial nos casos em que mínina lesão ao rim é imperiosa.
