[Summary of the existing knowledge about electronic cigarettes]. / Az elektronikus cigarettáról meglévo ismeretek összefoglalása.

The decreasing proportion of smokers due to smoking restrictions have led producers to invent and disseminate electronic cigarettes (e-cigarettes) worldwide as a new form of nicotine enjoyment. This review summarizes the existing knowledge about e-cigarettes based on publications of PubMed, and on reviews and research data published by national and international scientific institutions. Present knowledge about the composition of e-cigarettes confirms that they are harmful products since their vapor is equally detrimental to the health of users and bystanders. Their benefits in smoking cessation still have not been justified by adequate scientific evidence, however, it has been proven that e-cigarettes uphold nicotine addiction and may increase the risk of starting conventional cigarette use by youth. In order to ensure the results of tobacco control policy and to assist smoking cessation, the same regulations are to be applied to e-cigarettes as to conventional tobacco products.

Tobacco endgame measures and their adaptation in selected European countries: A narrative review synthesis.

Due to the continued detrimental effects of tobacco use, a growing number of countries are embracing the idea of tobacco endgame, meaning ending the tobacco epidemic instead of controlling it. This narrative review aims to synthesize and update the evidence from earlier scientific reviews on effective tobacco endgame measures, as well as to assess their integration to current national strategies among European countries with official tobacco endgame goals. The synthesis of the prior scientific literature found most evidence on product-focused and some evidence for supply-focused policies. Little evidence was detected for user- and institutional-focused measures. An update for the tobacco-free generation measure showed uncertainty in reducing smoking prevalence, especially for adolescents' reactions to age-restrictive laws. All the countries that established a tobacco endgame strategy have included product standards in their measures, predominantly based on European Union regulations on conventional tobacco products, yet standards above this level and considering other products were also common. Cessation measures were given strong emphasis in strategies, yet none of the countries linked these to specific endgame measures. Despite commonly mentioning vulnerable groups, such as youth and pregnant women, adoption of measures to reduce tobacco use among these groups was scarce. Lastly, the decline in tobacco use seems to be modest, implying challenges in meeting the endgame goals. To meet these goals, European countries should reinforce the implementation of known effective tobacco control measures such as tax increases. Furthermore, new innovative strategies and measures to meet the objective of an endgame should be explored.

Diversity of picornaviruses in rural Bolivia.

The family Picornaviridae is a large and diverse group of viruses that infect humans and animals. Picornaviruses are among the most common infections of humans and cause a wide spectrum of acute human disease. This study began as an investigation of acute flaccid paralysis (AFP) in a small area of eastern Bolivia, where surveillance had identified a persistently high AFP rate in children. Stools were collected and diagnostic studies ruled out poliovirus. We tested stool specimens from 51 AFP cases and 34 healthy household or community contacts collected during 2002-2003 using real-time and semi-nested reverse transcription polymerase chain reaction assays for enterovirus, parechovirus, cardiovirus, kobuvirus, salivirus and cosavirus. Anecdotal reports suggested a temporal association with neurological disease in domestic pigs, so six porcine stools were also collected and tested with the same set of assays, with the addition of an assay for porcine teschovirus. A total of 126 picornaviruses were detected in 73 of 85 human individuals, consisting of 53 different picornavirus types encompassing five genera (all except Kobuvirus). All six porcine stools contained porcine and/or human picornaviruses. No single virus, or combination of viruses, specifically correlated with AFP; however, the study revealed a surprising complexity of enteric picornaviruses in a single community.

[Smoking habits in Hungary: analysis based on surveys of the past decade]. / Dohányzási szokások Magyarországon: az utóbbi évtized felméréseinek elemzése.

Passing the amendments to the anti-smoking law in Hungary indicates a firm determination of the Department of Health to curb tobacco use. Professional steps were destined to follow policies and control measures. The Methodological Support Center for Smoking Cessation began operation at the National Korányi Institute of Tuberculosis and Pulmonology, Budapest, Hungary in 2012. The objective is to provide methodological assistance for evidence based smoking cessation support. The Center aspires to unite and direct the activities aimed at tobacco control, as well as initiate the drafting of appropriate medical guidelines. The Center works to ensure that information regarding smoking and personalized cessation support reaches wide range of Hungarian smokers through individual group and telephone counseling methods. Analysis of the results of national surveys conducted during the past decade on the adult population reveals that the proportion of daily smokers in Hungary has decreased to 28-29%. The proportion of men smokers (32-34%) indicates a more significant decrease, while the proportion of women smokers (24-25%) levels. Groups that are most affected by increased risk of smoking are people with low level of education, those facing economic hardship, the age groups of 17-34 and 35-64 years and women.

[The impact of the COVID-19 epidemic on the course of the most common respiratory diseases]. / A COVID­19-járvány hatása a leggyakoribb légzoszervi megbetegedések lefolyására.

INTRODUCTION: SARS-CoV-2 has defined our everyday lives over the past three years and by constituting a serious risk factor for patients with pre-existing respiratory illnesses, it placed an unexpected burden on the health care systems worldwide. OBJECTIVE: The aim of this study was to explore the association between COVID-19 and pre-existing respiratory comorbidities such as chronic obstructive pulmonary disease (COPD) and asthma. METHOD: In our current study, we retrospectively processed the data of nearly 29 000 Hungarian patients. RESULTS: We found that COPD was directly associated with the severity of COVID-19 and slightly increased the risk of intensive care unit admission and the need for mechanical ventilation during the SARS-CoV-2 infection. On the other hand, the presence of asthma influenced neither the severity of COVID-19 nor the need for intensive care unit admission or mechanical ventilation significantly. DISCUSSION: International studies suggest that COPD does not significantly increase the risk of SARS-CoV-2 infection. However, the likelihood of hospitalization due to COVID-19 is much higher in COPD patients and the presence of COPD is associated with a more severe disease course. Given the structural alterations and abnormal regeneration processes of the airways that occur during lung injury in COPD patients, these individuals require increased attention and personalized rehabilitation protocols after the onset of the viral infection. CONCLUSION: Altogether, the assessment of clinical manifestations associated with different COPD phenotypes (as well as other chronic lung diseases) and SARS-CoV-2 infection is essential for the implementation of personalized therapeutic approach in the future.

Tobacco endgame in the WHO European Region: Feasibility in light of current tobacco control status.

INTRODUCTION: To assess the feasibility of developing World Health Organization (WHO) European Region countries' goals and measures in line with tobacco endgame objectives, information on the current tobacco control context and capacity is needed. The aim of this study was to assess the implementation of the Framework Convention on Tobacco Control (WHO FCTC) and MPOWER measures in the region. METHODS: In this cross-sectional study we used data from the WHO FCTC implementation reports and MPOWER from 2020 in 53 WHO European Region countries. Six domains (i.e. capacity, taxation and price policies, other national key regulations, public awareness raising and communication, tobacco use cessation, and monitoring) were formed. Subsequently, available indicators under these domains were scored and the level of implementation was computed for each country. Mann-Whitney tests were carried out to compare the scores between the group of countries with and without official endgame goals. RESULTS: Overall, implementation of the WHO FCTC with the selected indicators at the country level ranged from 28% to 86%, and of MPOWER from 31% to 96%. Full implementation was achieved by 28% of WHO FCTC Parties in the region in taxation and price policies, 12% in public awareness raising and communication, and 42% in monitoring. In capacity, tobacco use cessation and other national key regulations, none of the Parties in the region reached full implementation. Overall median WHO FCTC scores were significantly higher in countries with official endgame goals than in those without (p<0.001). CONCLUSIONS: There is unequal implementation of both WHO FCTC and MPOWER measures among WHO European Region countries. MPOWER and WHO FCTC provide all the measures for the necessary first steps, followed by innovative measures, to accomplish tobacco endgame goals.
