Oral health and systemic inflammatory, cardiac and nitroxid biomarkers in hemodialysis patients

Periodontal diseases have systemic inflammatory effects and have been adversely associated with cardiovascular diseases, which are also the most frequent cause of death in the end-stage renal disease. The aim of this cross-sectional study was to investigate the oral health and serum biomarkers among the hemodialysis (HD) patients in Slovenia. 111 HD patients were periodontally examined and their sera were assayed for C reactive protein (CRP), cardiac troponin T (TnT), nitrite/nitrate (NOx) and antibody levels to A. actinomycetemcomitans and P. gingivalis. The association of oral health with systemic response was analyzed with Kruskal-Wallis test, Fisher?s exact test and multivariate linear regression. Bleeding on probing without periodontal pockets was present in 5.2%, calculus without periodontal pockets in 42.1%, shallow periodontal pockets in 39.5% and deep periodontal pockets in 13.2% of dentate patients. There were 28.8% edentulous participants. 63.1% of the patients had CRP levels higher than 3 mg/L and 34.2% higher than 10 mg/L. TnT was detectable in all participants, with 25.2% exhibiting levels higher than 100 ng/L. The median level of NOx was 43.1 µmol/L. Participants with higher CRP were more likely to be edentulous and have higher TnT levels. A direct association of oral health with TnT or NOx was not detected. HD patients in Slovenia have compromised oral health and increased serum inflammatory and cardiac biomarkers. Edentulousness was an independent predictor for the increased CRP, indicating a need for improved dental care to retain the teeth as long as possible

Smjernice za farmakološko liječenje epilepsije

SAŽETAK Međunarodne smjernice za farmakološko liječenje epilepsija općenite su, sveobuhvatne i ne prepoznaju lokalne specifičnosti poput ekonomskih i tehničkih mogućnosti u pojedinim državama, dostupnosti pojedinih antiepileptika ili drugih metoda liječenja i slično. Stoga se nameće potreba izrade nacionalnih smjernica, čiji su zapravo temelj međunarodne smjernice Internacionalne lige protiv epilepsije. Hrvatske smjernice za farmakološko liječenje epilepsija plod su suradnje svih relevantnih stručnih društava i referentnih centara u RH, na čelu s Hrvatskom ligom protiv epilepsije te Hrvatskim neurološkim društvom i Hrvatskim društvom za dječju neurologiju Hrvatskoga liječničkog zbora, a odražavaju aktualne socioekonomske i regulatorne specifičnosti u našoj zemlji, najnovije spoznaje farmakoloških profila i učinkovitosti pojedinih antiepileptika kao i ekspertna mišljenja. Antiepileptička terapija se uvodi nakon postavljanja dijagnoze epilepsije, stoga profilaktička primjena nije opravdana. Nakon postavljanja dijagnoze potrebno je bolesnika informirati o prognozi bolesti, mogućnostima liječenja i samopomoći, životnim ograničenjima te mogućim neželjenim događajima. Ciljevi farmakoterapije epilepsija su potpuna kontrola napada uz izbjegavanje nuspojava te održavanje ili poboljšanje kvalitete života. Zlatni standard liječenja je monoterapija odnosno primjena adekvatnog antiepileptika u adekvatnoj dozi. Izbor i titracija lijeka su individualni, a temelje se na smjernicama za liječenje pojedinih vrsta napada, karakteristikama bolesnika i regulatorno specifičnim čimbenicima. Nakon neuspjeha inicijalne monoterapije, potrebna je reevalucija anamnestičkih i dijagnostičkih podataka te potom postupna i spora zamjena antiepileptika. Racionalna politerapija podrazumijeva kombinaciju dvaju antiepileptika različitih mehanizama djelovanja, prvog ili eventualno drugog izbora za postavljenju dijagnozu, niskoga interakcijskog potencijala, različitog profila nuspojava i sinergističkog ili aditivnog djelovanja. Zamjena generičkih ili originalnog i generičkog oblika lijeka nije preporučljiva, a poglavito nakon postizanja remisije ili prilikom uzimanja visokih doza lijeka. Ukidanje antiepileptičke terapije treba biti postupno i sporo, u slučaju politerapije jedan po jedan lijek, a u donošenju odluke o ukidanju, kao i o uvođenju antiepileptika, mora biti uključen bolesnik i njegova obitelj

Structure of historical brass tongues and shallots from Baroque organs

The composition and microstructure of historic tongues and shallots from reed pipes of various Baroque organs has been studied. They contain Cu-Zn solid solution (α-brass with 23-29 wt. % Zn) and lead particles. Lead is mainly present as spherical bulk or lens-like grain boundary (GB) inclusions. However, in two samples Pb wets the brass GBs. In this case Pb forms the branched root-like structures. Grain size in brass scatters from 10 to 200 μm. Around 50% of all GBs in brass are Σ=3 twin GBs. The high-indexed coincidence site lattice facets were observed in twin GBs. The increase of number of various facets roughly correlates with decreasing grain size. It may indicate the variation in annealing temperature used by organbuilders in Baroque Era. The annealing temperature has been estimated using the faceting phase diagram for twin GBs in Cu

Brain MRI post-processing with MAP07 in the preoperative evaluation of patients with pharmacoresistant epilepsy – Croatian single centre experience

Objective: This study aimed to determine the role of brain MRI post-processing method MAP07 (Morphometric Analysis Program) in detecting epileptogenic brain lesions in patients with pharmacoresistant epilepsy (PE). MAP07 is a sophisticated diagnostic program that offers several morphometric maps and facilitates the detection and localization of hippocampal sclerosis (HS), focal cortical dysplasias (FCD), and other types of cortical malformations, which could be undetected by conventional visual MRI analysis (CVA). ----- Methods: 120 patients aged > 16 years with PE have been recruited. 3 T MRI was performed according to epilepsy imaging protocol followed by image postprocessing with a fully automated MATLAB script, MAP07, by applying SPM5 algorithms. Statistical analysis was performed in IBM SPSS Statistics, version 25.0. ----- Results: Analysis in our patients showed a high sensitivity of MAP07 with low specificity and with a high proportion of false-positive patients. After MRI analysis, out of 120 patients, 32 were found to have no structural abnormalities by conventional visual analysis in whom after MAP07 in 5 patients structural lesions were found (in one HS, in one FCD, in two perinatal vascular lesions, and in one hippocampal hyperintensity). There was a quite high overall coincidence of the findings of MAP07 and MRI for the detection of FCD, HS, perinatal ischemia/chronic vascular lesions, heterotopias, and polymicrogyria (kappa coefficient above 0.700). ----- Conclusions: MAP07 analysis is a useful, additional, and automated method that may guide re-evaluation of MRI by highlighting suspicious cortical regions, as a complementary method to CVA, by enhancing the visualization of cortical malformations and lesions

Single oral inoculation with Escherichia coli (ATCC 25922) stimulates generalised production of nitric oxide in mice

Nitric oxide (NO) production was investigated in the lungs, thoracic aorta, heart, liver, spleen, kidneys and brain of mice inoculated orally with Escherichia coli ATCC 25922. Detection of NO was performed by electron paramagnetic resonance (EPR) using diethyldithiocarbamate (DETC) spin trap. Nitric oxide synthase (NOS) inhibitors [nonselective: L-NAME and inducible NOS (iNOS) selective: 1400W] were used to determine the source of NO. Spin-trap only and untreated mice were included as controls. Within 2.5 hours (h) of a single oral inoculation with E. coli half of the animals had increased NO levels in all investigated organs. Thereafter the signals dropped before increasing again to reach maximal median values by 25 h in all organs of all inoculated mice. The most intense response occurred in livers, followed by aorta and lungs. Early (2.5 h) inhibition of the signal was achieved using both NOS inhibitors. L-NAME was also effective at 25 h, while 1400W-treated mice had increased NO levels beyond 7 h. The generalised increase in NO production in the short and longer term indicates a host response to E. coli administered by the oral route of infection
