Uloga nagiba padina, gustoÄe vrtaÄa i analize vodne bilance u izdvajanju kompleksnog slivnog podruÄja rijeke SlunjÄice (Hrvatska)
Due to the high vulnerability of the karst aquifer to the surface contaminants, a precisely defined catchment area has the highest priority. In this study, the influence of slope inclination, the doline density analysis, and the water budget analysis in the delineation process of a complex karst catchment area is discussed. To define hydrogeological role of lithological units, cross sections of slope inclination and doline density were combined with hydrogeological cross sections, while the degree of karstification was used to describe the permeability of rock units. The verification of karst catchment delineation area was performed with water budget analysis. The methodology used for the determination of hydrogeological behavior and delineation of a complex karst catchment area (SlunjÄica River basin, Croatia) is shown with the flow diagram. It has been found that the highest doline density appears in the range from 0 to 1Ā° of the slope inclinations, and that it decreases with a higher slope degree. Although the results of this study confirm that even with the relatively small number of input data it is possible to define the karst catchment area, it must be emphasized that the doline density analysis presents an indispensable tool in the research related to the definition of karst catchment areas.Radi vrlo visoke prirodne ranjivosti krÅ”kih vodonosnika, izrazito je važno precizno odreÄivanje slivne povrÅ”ine. U okviru ovog istraživanja razmatran je utjecaj nagiba terena, gustoÄe vrtaÄa i vodne bilance u procesu razdvajanja složenih krÅ”kih slivnih podruÄja. Za definiranje hidrogeoloÅ”ke uloge pojedinih litoloÅ”kih jedinica koriÅ”tena je kombinacija hidrogeoloÅ”kih profila s podacima o gustoÄi vrtaÄa i nagibu terena, dok je za opis propusnosti pojedinih stijenskih jedinica koriÅ”ten stupanj okÅ”enosti. Za verifikaciju i provjeru izdvojenih slivnih podruÄja koriÅ”tena je vodna bilanca. Metodologija koriÅ”tena za utvrÄivanje hidrogeoloÅ”ke uloge pojedinog podruÄja i odreÄivanje slivnog podruÄja (rijeka SlunjÄica, Hrvatska) prikazana je dijagramom toka. UtvrÄeno je da se najveÄe vrijednosti gustoÄe vrtaÄa pojavljuju u dijelovima terena s nagibom padina od 0 to 1Ā°, te se smanjuju s poveÄanjem nagiba padina. Iako rezultati istraživanja potvrÄuju da je Äak i s malim brojem ulaznih podataka moguÄe odrediti slivno podruÄje u krÅ”u, potrebno je dodatno naglasiti da analiza gustoÄe vrtaÄa predstavlja nezamjenjiv alat prilikom istraživanja vezanih za odreÄivanje slivnih podruÄja u krÅ”u
Difference in anaemia expression in men and women with renal failure treated with peritonial dyalisis
Anemija je poznata i Äesta komplikacija kroniÄnoga zatajenja bubrega (KZB) sa znaÄajnim utjecajem na morbiditet i mortalitet, smanjenje kvalitete života i troÅ”kove zdravstvene zaÅ”tite. Smjernice za lijeÄenje anemije KZB ne odreÄuju spolno specifiÄne ciljne vrijednosti hemoglobina (Hb). Iako meÄu spolovima postoje sliÄnosti u temeljnoj fiziologiji anemije KZB, sve je viÅ”e dokaza dokaza o razliÄitom odgovoru na anemiju. IzvrÅ”ili smo retrospektivnu analizu anemije bolesnika tijekom prvih Å”est mjeseci lijeÄenja peritonejskom dijalizom (PD). Spolne razlike razine Hb koje postoje kod zdrave populacije održane su i kod terminalne faze KZB na poÄetku lijeÄenja PD-om, kao i nakon Å”est mjeseci lijeÄenja. VeÄi udio žena (15-30%) zahtijeva uvoÄenje lijekova za stimulaciju eritropoeze (LSE), za razliku od muÅ”karaca. ProsjeÄna mjeseÄna doza eritropoetina bila je 70% veÄa kod žena. UnatoÄ nižim apsolutnim razinama Hb, žene pokazuju viÅ”e razine Hb u odnosu na referentne vrijednosti specifiÄne za spol, nego muÅ”karci.Anemia is recognized as a common complication of chronic kidney disease (CKD) with a significant impact on morbidity and mortality and a decline in quality of life and health care costs. Guidelines for the treatment of CKD anemia do not specify sex-specific Hb targets. There are similarities among genders in the basic physiology of anemic CKD, but there is growing evidence with respect to differential responses to anemia between genders.
We performed a retrospective analysis of patients during the first six months of peritoneal dialysis (PD) treatment. Gender differences in Hb level seen in the healthy populations are maintained in subjects with end stage renal disease at PD inception and after six months of treatment. A greater proportion (15-30%) of females require erythropoiesis stimulating agents (ESA) than males. The average monthly EPO dose was 70% higher in females. Despite lower absolute levels of Hb, women manifest higher Hb levels relative to gender-specific normative values than men
Epidemiology and Clinical Presentation of Inflammatory Bowel Disease in Zadar County, Croatia
Results of the retrospective, population-based study, 2000ā2010, on inflammatory bowel disease, ulceratice colitis (UC) and Crohn\u27s disease (CD), from Zadar County, have been presented and compared with world experience and com- parative data from Primorsko-Goranska and Vukovarsko-Srijemska Counties. The average incidence rates (per 100 000) were 8.2 and 8.4, for UC and CD, respectively. Prevalence rates, at the end of the follow up, were 133.9 for UC and 111 for CD. Constant increase in the incidence rates for both, UC and CD, have been recorded, for CD more prominently in the second part of the follow up, 2006ā2010. Prevalence rates have being continuosly rased for both diseases, data for UC ex- ceeding that for CD. Results of data comparison among the counties contribute in favour to the hypothesis of Zadar County as a rapidly developing area and strongly argue against the existence of the North-South gradient between Vukovarsko-Srijemska and Zadar Counties
KroniÄne nezarazne bolesti kod hrvatskih branitelja u odnosu na opÄu populaciju: 25 godina nakon rata
Many published reports have documented an increased prevalence of chronic
medical conditions among veterans, but there were only a few studies that compared these increases
with the general population. The aim of this study was to determine differences in chronic medical
conditions between Croatian war veterans and the general population. This study included two
groups of subjects, i.e. 1453 participants who are Croatian war veterans and 1429 participants from
the general population. Medical history, physical examination, laboratory tests and specific diagnostic
procedures were taken during systematic physical examination in both groups. The prevalence
of hypertension, diabetes, hyperlipidemia, hypothyroidism and hyperthyroidism, chronic obstructive
pulmonary disease, coronary heart disease, malignancy, psychiatric diseases, cholelithiasis, nephrolithiasis,
smoking and alcohol consumption was analyzed. Croatian war veterans were found to be more
likely to develop hypertension than individuals in the general population (29.5% vs. 24.3%), as well
as diabetes (7.3% vs. 3.8%), hyperlipidemia (56.4% vs. 27.3%), hyperthyroidism (3.1% vs. 0.8%), coronary
heart disease (4.3% vs. 1 %), malignancy (4.1% vs. 2.2%), psychiatric diseases (15.4% vs. 1.1%),
and alcohol consumption (53% vs. 29%). Significant difference was found in favor of the general
population for hypothyroidism (14.3% vs. 8%). There were no differences in the prevalence of chronic
obstructive pulmonary disease, cholelithiasis, nephrolithiasis, and smoking. Our findings confirmed
the hypothesis of a higher prevalence of cardiovascular diseases, malignancy and psychiatric diseases
among Croatian war veterans and emphasized the need of better control of their medical conditions.PoveÄana uÄestalost kroniÄnih bolesti meÄu veteranima dokumentirana je kroz brojna istraživanja, no samo ih je nekoliko
studija usporeÄivalo s opÄom populacijom. Cilj ovog istraživanja bio je utvrditi razlike u pojavnosti kroniÄnih bolesti izmeÄu
hrvatskih branitelja i opÄe populacije. Ovo istraživanje obuhvatilo je dvije skupine ispitanika, 1453 hrvatskih branitelja i
1429 sudionika iz opÄe populacije. Anamneza, fizikalni pregled, laboratorijske pretrage i specifiÄni dijagnostiÄki postupci
provedeni su tijekom sistematskog fizikalnog pregleda u obje skupine. Analizirana je uÄestalost hipertenzije, Å”eÄerne bolesti,
hiperlipidemije, hipotireoze i hipertireoze, kroniÄne opstruktivne pluÄne bolesti, koronarne bolesti, malignih bolesti, psihijatrijskih
bolesti, kolelitijaze, nefrolitijaze, puÅ”enja i konzumacije alkohola. UtvrÄeno je da hrvatski branitelji imaju veÄu
vjerojatnost za razvoj hipertenzije (29,5% prema 24,3%), dijabetesa (17,3% prema 3,8%), hiperlipidemije (56,4% prema
27,3%), hipertireoze (3,1% prema 0,8%), koronarne bolesti srca (4,3% naspram 1%), zloÄudne bolesti (4,1% naspram 2,2%),
psihijatrijske bolesti (15,4% naspram 1,1%) i ÄeÅ”Äu konzumaciju alkohola (53% naspram 29%) nego pojedinci u opÄoj populaciji.
UoÄena je znaÄajna razlika u korist opÄe populacije za hipotireozu (14,3% naspram 8%). Nije bilo razlika u uÄestalosti
kroniÄne opstruktivne pluÄne bolesti, kolelitijaze, nefrolitijaze i puÅ”enja. NaÅ”i nalazi potvrdili su hipotezu o viÅ”oj uÄestalosti
kardiovaskularnih bolesti, malignih i psihijatrijskih bolesti meÄu hrvatskim braniteljima te naglasili potrebu bolje kontrole
njihovog zdravstvenog stanja
Helicobacter Pylori Infection and Acute Stroke
The aim of this investigation was to determine whether Helicobacter pylori infection (HBPI) is an independent risk factor for acute noncardioembolic stroke, and also if there is a link between HBPI and other established and well-known risk factors for stroke, as well, to find if there is link between HBPI and severity of disease. In this prospective single centre study where enrolled 82 patients with acute stroke and control group was consistented 93 healthy individuals. The results of this study showed no difference between H.pylori seropositivity distribution in the investigate and control group (25.8 vs. 34.8%), additionally, there was no significant difference on the severity of the disease. Furthermore there was no evident association between acute stroke and HBPI in the patientes with three and more risk factors, but we found significant link between HBPI and carotid stenosis. Further studies are needed to clarify the possible causal relation between infection by this organism and stroke. It is necessary not only the elucidate of pathophysiology related to the association, but also to evaluate whether antibiotic treatment may result in clinical benefit of the patient
