Hepatitis A and hepatitis E are enteric transmitted viral diseases occurring in epidemic and sporadic forms especially in developing countries. Previous studies in Turkey showed that most residents are infected with HAV by the second decade of life. Since HEV is generally transmitted by the same route as HAV we conducted a community-based seroprevalence study for HAV and HEV infection in Ahatli area in Antalya, Turkey where socioeconomic conditions are low. Anti-HAV total immunoglobulin was tested by using a microparticle EIA (Axsym-Abbott Lab). Anti-HEV IgG was assayed by a micro ELISA method (Genelabs-Singapore). Of the 338 sera tested, 112 (33.1%) were positive for anti-HAV total antibody. Anti-HEV Ig G was detected in three (0.89%) of the serum samples. Seropositivity rates of HAV in preschool and school children were 19.9% and 43.9% respectively (p<0.001). No antibody to HEV was detected in preschool children, while the prevalence of anti-HEV Ig G was 1.6% in children attending school. Our data showed that seroprevalence of anti-HAV is high among children samples but HEV infection appears to be relatively rare in pediatric age groups.

Our paper seeks answers to the following questions: What are the determinants of permanent emigration from Poland and how do they vary for specific economic age groups (pre-working, working, and post-working age)? Do the causes of permanent emigration differ over space in these categories, and if so, how? We applied GIS and ESDA instruments, including geographically weighted regression, which allowed us to identify the variability of regression coefficients in the geographical space. Our research indicated socio-economic factors (among others: poviats budget income, feminisation rate, unemployment rate), which, with varying force and in varying directions, affected the studied variable in specific parts of the country. The analyses were performed on the basis of statistical data on the numbers of de-registrations for residence abroad in Poland’s NUTS-4 in three economic age groups (pre-working, working, and post-working age) for the time span from 2005 to 2013.

The water soluble proteins of the lens collected from different age group of the fish Catla catla were subjected to Sephadex G 200 gel filtration to fractionate and to characterize the protein and further to determine the elution volume (Ve) of different fractions. The relative proportion of each fraction was also calculated. Total number of fractions F1 to F4 was discernible through gel filtration. The molecular weight of these varied from 35,000 Da to 640,000 Da. Three subfractions were also noted in F1 fraction. Interesting observations were, presence of a, bH, bL crystallins in all age groups and LMW proteins in older age group. a-crystallin present in major amounts in comparison to bH & bL crystallins. Decrease of a-crystallins (except in age group II) with the increase of age, counter balanced by the increase of bH crystallins. Increase of bH crystallins was followed by the decrease of bL crystallins. Results suggest that proportionate distribution of different classes of proteins determined by column chromatography is widely variable.

Abstract  

A statistical analysis is made of two data sets and it is found that the distribution of major scientific and technological achievements in terms of the age of those achievement makers is Weibull distribution. Pearson'sx 2 test results are satisfactory. This finding holds for different centuries, different nations and different disciplines.

Összefoglaló. Bevezetés: Nagyszámú kutatás igazolta, hogy a dohányzás növeli a legjelentősebb krónikus betegségek kockázatát. Habár 2009 óta csökkenő tendenciát mutat Magyarországon a hagyományos dohányzók aránya, az e-cigarettát kipróbálóké az utóbbi években folyamatosan növekszik. Célkitűzés: A 2018-ban a felnőtt lakosság körében végzett Népegészségügyi Felmérés dohányzásra és e-cigaretta-használatra vonatkozó eredményeinek bemutatása az előző vizsgálatok tükrében. Módszer: A kérdőíves felmérésben 1586 fő került személyesen lekérdezésre. Az iteratív súlyozás a többlépcsős mintavételi designhatást és a 2016-os mikrocenzus adatait vette figyelembe. Eredmények: 2018-ban a dohányzók aránya a magyar felnőtt lakosság körében 28,7% (95% MT: 26,3–31,1%), az e-cigarettát használók aránya pedig 1,7% (95% MT: 1,1–2,5%) volt. Az iskolai végzettség a 65 év alattiak esetében a dohányzást befolyásoló tényező volt (EH: 3,32; 95% MT: 2,53–4,34), de a 65 éves és annál idősebb korcsoportban már nem (EH: 1,11; 95% MT: 0,59–2,09). Az e-cigarettát kipróbálók és használók között a leginkább említett (54,3% 95% MT: 44,0–64,5%) motivációs tényezőcsoport a dohányzásról való leszokással, az ártalomcsökkentéssel és a visszaesés megelőzésével volt kapcsolatos. A 65 éves és idősebb korcsoportban a dohányzók aránya 2015-höz képest emelkedett. 2018-ban az alapfokú iskolai végzettségűek körében volt a legmagasabb a dohányzók aránya, míg 2014-ben az érettségivel nem rendelkező középfokú végzettségűek körében. Következtetés: Bár összességében csökkent, az alacsony iskolai végzettségűek és az idősek körében emelkedett a dohányzók aránya Magyarországon. Az e-cigarettát kipróbálók és használók száma növekvő tendenciát mutat hazánkban. Eredményeink az alacsony iskolai végzettségűekre kiemelten fókuszáló, megelőző és leszokást támogató népegészségügyi alprogramokat is tartalmazó komplex beavatkozást sürgetnek.

Summary. Introduction: The body of evidence suggests that smoking increases the risk of the most prevalent chronic diseases. Although the proportion of traditional smokers in Hungary has been on a declining trend since 2009, the proportion of those who tried e-cigarette has been steadily increasing in recent years. Objective: To present – in the light of previous studies – the results of the Public Health Survey among adults in 2018 on smoking and e-cigarette use. Method: 1586 persons were personally interviewed in a survey. The iterative weighting algorithm considered both the design effect of multistaged sampling and the 2016 Hungarian microcensus. Results: In 2018, the proportion of smokers in the Hungarian adult population was 28.7% (95% CI 26.3–31.1%), and the proportion of e-cigarette users was 1.7% (95% CI 1.1–2.5%). Educational level was a predictor of smoking among respondents younger than 65 years old (OR 3.32; 95% CI 2.53–4.34), but not for those aged 65 years or older (OR 1.11; 95% CI 0.59–2.09). Among e-cigarette ever or current users, the most commonly mentioned (54.3% 95% CI 44.0–64.5%) motivational factor-group to try or use e-cigarettes included motivations to quit smoking, to reduce harm, and to avoid relapsing. In the population aged 65 years old or older, the proportion of smokers increased compared to 2015. The proportion of smokers was the highest among those with primary education in 2018, while in 2014, it was the highest among those with secondary education without a graduation certificate. Conclusion: In Hungary, although overall smoking rates are declining, the smoking rate in the low educational group and among the elderly increased. The number of people trying or using e-cigarettes is showing an increasing trend in our country. Our results call for a complex public health intervention program including prevention and smoking cessation supporting subprograms with high focus on those with primary education.
