    Helicobacter pylori is a Gram-negative bacterium that colonizes the stomach almost half the world's population. Infection of the stomach with this bacteria leads to chronic gastritis and peptic ulcer disease. Further, long infection with H. pylori can cause the development of gastric cancer disease. Therefore, the eradication of H. pylori is very important, but it is difficult because the resistance to the antibiotic regimes, especially metronidazole and clarithromycin increases. Therefore, the compounds with antimicrobial activity but not antibiotics are very important in the treatment of H. pylori infections, especially if they have an effect on H. pylori strains resistant to antibiotics. Plants and fungi are a very important source of compounds with antimicrobial activity. Previous studies have shown that fungi such as Pseudonocardia sp. CL38489, Phanerochaete velutina CL6387, Hericium erinaceus, Fomes fomentarius and Antrodia camphorata can be an important source of compounds with activity against H. pylori. Different groups of chemical compounds may be responsible for manifested antibacterial activity, including phenols and beta-glucans. In addition to antibacterial activity, an important mechanism of action against the bacterium H. pylori is the inhibition of the adhesion of bacteria to the gastric epithelium.Helicobacter pylori je Gram negativna bakterija koja kolonizira želudac skoro polovine svetske populacije. Infekcija želuca ovom bakterijom dovodi do hroničnog gastritisa i peptičkog ulkusa. Duga infekcija bakterijom H. pylori može da dovede do razvoja gastričnog kancera. Zbog toga je eradikacija H. pylori veoma važna, ali je otežana jer se rezistencija na antibiotoke, posebno metronidazol i klaritromicin, povećava. Zbog toga su jedinjenja sa antimikrobnim delovanjem koja nisu antibiotici veoma važna u tretmanu H. pylori infekcije, naročito ukoliko deluju na H. pylori sojeve koji su rezistentni na antibiotike. Biljke i gljive predstavljaju veoma važne izvore jedinjenja sa antimikrobnim delovanjem. DosadaÅ”nja istraživanja gljiva, pokazala su da gljive Pseudonocardia sp. CL38489, Phanerochaete velutina CL6387, Hericium erinaceus, Fomes fomentarius i Antrodia camphorata mogu biti značajan izvor jedinjenja sa aktivnoŔću protiv bakterije H. pylori. Različite grupe hemijskih jedinjenja mogu biti odgovorne za ispoljenu antibakterijsku aktivnost, uključujući fenole i beta-glukane. Pored antibakterijske aktivnosti, značajan mehanizam delovanja sastojaka pečuraka protiv bakterije H. pylori je i inhibicija adhezije bakterije za gastrični epitel

    Komercijalni uzorci nadzemnih delova Origanum vulgare L. i Ocimum basilicum L. (Lamiaceae) su koriŔćeni za određivanje antimikrobne aktivnosti. Aktivnost ekstrakata različite polarnosti je testirana protiv izabranih mikroorganizama, uključujući laboratorijski soj Helicobacter pilori NCTC 12868. Testirani ekstrakti su imali umerenu aktivnost. Ekstrakti O. vulgare su bili aktivniji protiv bakterija, posebno Gram pozitivnih bakterija sa minimalnim inhibitornim koncentracijama (MIK) između 62,5 i 125 Ī¼g/mL, od ekstrakata O. basilicum koji su pokazali aktivnost protiv Candida albicans (MIK 125 Ī¼g/mL). Cikloheksanski ekstrakt O. vulgare nije pokazao antimikrobnu aktivnost na testirani H. pylori, dok su ostali testirani ekstrakti bili aktivni sa MIK vrednostima između 250 Ī¼g/mL i 500 Ī¼g/mL. Identifikovana i kvantifikovana ruzmarinska kiselina i druga polarna jedinjenja mogu predstavljati aktivna jedinjenja sa antibakterijskom aktivnoŔću u ovim začinima.The commercial samples of aerial parts of Origanum vulgare L. and Ocimum basilicum L. (Lamiaceae) were tested for antimicrobial activity. The activity of the extracts with different polarity was tested against a panel of microorganisms, including laboratory strain Helicobacter pylori NCTC 12868. The tested extracts showed a moderate activity. The extracts of O. vulgare were more active against bacteria, especially against Gram positive bacteria with the minimal inhibitory concentration (MIC) between 62.5 and 125 Ī¼g/mL, than the extracts of O. basilicum which were active against Candida albicans (MIC 125 Ī¼g/mL). Cyclohexane extract of O. vulgare did not show any activity against tested H. pylori, while all other tested extracts were active with MICs between 250 Ī¼g/mL and 500 Ī¼g/mL. Identified and quantified rosmarinic acid and other polar compounds could be active antibacterial compounds in these spices

    Vokalni profesionalci su osobe kojima je glas osnovno sredstvo za obavljanje posla, u pravilu, i glavni izvor prihoda za život. Odgojitelji i učitelji pripadaju skupini vokalnih profesionalaca. Izloženost većim glasovnim naporima čini ove dvije skupine posebno podložnim glasovnim poremećajima. Cilj rada je ispitati i usporediti rezultate samoprocjene glasa u skupinama učitelja i odgojitelja Voice Handicap Indexom (VHI), upitnikom za samoprocjenu glasa. U radu je primijenjena prevedena hrvatska inačica VHI upitnika. Ljestvica daje konačni nestandardizirani rezultat koji predstavlja stupanj subjektivnog doživljaja problema, a javljaju se kao posljedica poremećaja glasa. Uzorak čine dvije skupine ispitanika: učitelji (N=40) i odgojitelji (N=40). Rezultati istraživanja pokazuju da je skupina odgojitelja postigla statistički značajno viÅ”e rezultate na svim podljestvicama, kao i na ukupnom rezultatu VHI upitnika. Rezultati istraživanja upućuju na to da odgojitelji imaju viÅ”e subjektivnih teÅ”koća, povezanih s mogućim poremećajima glasa u odnosu na skupinu učitelja

    Urinary tract infections are inflammations processes on lower or upper parts of urinary tract. Therapy of urinary tract infections differs for complicated and non-complicated infections and site of infection. The aim of this paper is pharmacoeconomic analysis of different strategies in management of urinary tract infections from the perspective of Republic Fond for Health Insurance. The decision tree was constructed to evaluate costs and effectiveness of different strategies used for treatment of non-pregnant, adult women. As a positive outcome of the treatment number of cases where simptoms disapered is used. The results implied that the least costly strategy available is empiric treatment. More expensive but with greater outcomes was the strategy involving laboratory test together with empiric treatment. Although the empiric treatment proved to be cost-effective and in accordance with current recommendations and guidelines for therapy, recognition of the impact of this strategy upon antibiotic resistance may lead to conclusion that the dipstick strategy is superior strategy.Infekcije urinarnog trakta zahvataju donje i gornje delove urinarnog trakta. Terapija infekcija se razlikuje u zavisnosti da li su u pitanju komplikovane ili nekomplikovane infekcije kao i od mesta infekcije. Cilj ovog rada je farmakoekonomska analiza isplativosti primene različitih strategija u lečenju infekcija urinarnog trakta iz perspektive Republičkog fonda za zdravstveno osiguranje. Zarad procene troÅ”kova i efikasnosti primene različitih strategija u lečenju infekcija urinarnog trakta u odraslih žena koje nisu trudne konstruisano je drvo odlučivanja. Kao ishod lečenja posmatran je broj slučajeva u kojima je doÅ”lo do prestanka simptoma. Rezultati istraživanja su pokazali da je najisplativija strategija empirijska primena antibiotika. NeÅ”to skuplja i efikasnija strategija je primena laboratorijskih testova uz empirijsku primenu antibiotika. Iako je empirijska primena antibiotika troÅ”kovno isplativa i u skladu sa važećim preporukama i protokolima lečenja infekcije urinarnog trakta, ukoliko se razmotri i antibiotska rezistencija kao rastući zdravstveni problem, strategija primene dipstik testa može biti superiorna

These guidelines have been written by the representatives of the Croatian Society of Clinical Nutrition, Croatian Medical Association, Croatian Neurological Society, Croatian Medical Association, Croatian Society of Gastroenterology and Croatian Society of Nutritionists and Dietitians. The aim of these guidelines is to raise the awareness about NOD that is encountered in acute and chronic neurological diseases, especially in patients with stroke, extrapyramidal diseases, neuromuscular and demyelinisation diseases and dementia. We provide a detailed description of diagnostics of dysphagia, and we recommend the establishment of a multidisciplinary team for dysphagia involving neurologists, internists, speech therapists, dietitians, pharmacists and nurses with special competences for the management of NOD. An educated team member conducts diagnostics and rehabilitation in accordance with the validated tools, classifications and categorizations shown in these guidelines to allow a systematic and consistent treatment. The guidelines also provide detailed algorithms for introducing nutritional support ā€“ from the application of modified texture foods, proper hydration to artificial nutrition (enteral and parenteral nutrition)

    No full text
    Metabolic syndrome (MS) is a modern medical condition characterized by central obesity, hyperglycaemia, hypercholesterolemia and hypertension. The beneficial effects of mushrooms in lowering the symptoms of MS were known from both traditional and conventional medicine. Edible mushrooms, their extracts, polysaccharide fractions and isolated compounds possessed hypoglycaemic, cholesterol and triglyceride lowering ability, hypotensive effects, as well as weight managing activity by influencing satiety. The most active compounds are polysaccharides, called - glucans, as well as lectines and small compounds such as eritadenin, triterpenes, sterols and phenolic compounds
