1Transient elastography(Fibro Scan~?) with controlled attenuation parameter in the assessment of liver steatosis and fibrosis in patients with nonalcoholic fatty liver disease- Where do we stand?显示文摘Non-alcoholic fatty liver disease(NAFLD) is the most common cause of chronic liver disease worldwide. Currently, the routinely used modalities are unable to adequately determine the levels of steatosis and fibrosis(laboratory tests and ultrasonography) or cannot be applied as a screening procedure(liver biopsy). Among the non-invasive tests, transient elastography(Fibro Scan?, TE) with controlled attenuation parameter(CAP) has demonstrated good accuracy in quantifying the levels of liver steatosis and fibrosis in patients with NAFLD, the factors associated with the diagnosis and NAFLD progression. The method is fast, reliable and reproducible, with good intra- and interobserver levels of agreement, thus allowing for population-wide screening and disease follow-up. The initial inability of the procedure to accurately determine fibrosis and steatosis in obese patients has been addressed with the development of the obese-specific XL probe. TE with CAP is a viable alternative to ultrasonography, both as an initial assessment and during follow-up of patients with NAFLD. Its ability to exclude patients with advanced fibrosis may be used to identify low-risk NAFLD patients in whom liver biopsy is not needed, therefore reducing the risk of complications and the financial costs.Ivana Mikolasevic Lidija Orlic Neven Franjic Goran Hauser Davor Stimac Sandra Milic 2016World Journal of Gastroenterology2016,22,32:33
2Nonalcoholic fatty liver disease-A multisystem disease?显示文摘Non-alcoholic fatty liver disease(NAFLD) is one of the most common comorbidities associated with overweight and metabolic syndrome(Met S). Importantly, NAFLD is one of its most dangerous complications because it can lead to severe liver pathologies, including fibrosis, cirrhosis and hepatic cellular carcinoma. Given the increasing worldwide prevalence of obesity, NAFLD has become the most common cause of chronic liver disease and therefore is a major global health problem. Currently, NAFLD is predominantly regarded as a hepatic manifestation of Met S. However, accumulating evidence indicates that the effects of NAFLD extend beyond the liver and are negatively associated with a range of chronic diseases, most notably cardiovascular disease(CVD), diabetes mellitus type 2(T2DM) and chronic kidney disease(CKD). It is becoming increasingly clear that these diseases are the result of the same underlying pathophysiological processes associated with Met S, such as insulin resistance, chronic systemic inflammation and dyslipidemia. As a result, they have been shown to be independent reciprocal risk factors. In addition, recent data have shown that NAFLD actively contributes to aggravation of the pathophysiology of CVD, T2 DM, and CKD, as well as several other pathologies. Thus, NAFLD is a direct cause of many chronic diseases associated with MetS, and better detection and treatment of fatty liver disease is therefore urgently needed. As non-invasive screening methods for liver disease become increasingly available, detection and treatment of NAFLD in patients with MetS should therefore be considered by both(sub-) specialists and primary care physicians.Ivana Mikolasevic Sandra Milic Tamara Turk Wensveen Ivana Grgic Ivan Jakopcic Davor Stimac Felix Wensveen Lidija Orlic 2016World Journal of Gastroenterology2016,22,43:32
3Preventing post-endoscopic retrograde cholangiopancreatography pancreatitis: What can be done?显示文摘Post-endoscopic retrograde cholangiopancreatographypancreatitis(PEP) is the most common complication of endoscopic retrograde cholangiopancreatography. The incidence of post-endoscopic retrograde cholangiopancreatography(ERCP) pancreatitis varies substantially and is reported around 1%-10%, although there are some reports with an incidence of around 30%. Usually, PEP is a mild or moderate pancreatitis, but in some instances it can be severe and fatal. Generally, it is defined as the onset of new pancreatictype abdominal pain severe enough to require hospital admission or prolonged hospital stay with levels of serum amylase two to three times greater than normal, occurring 24 h after ERCP. Several methods have been adopted for preventing pancreatitis, such as pharmacological or endoscopic approaches. Regarding medical prevention, only non-steroidal anti-inflammatory drugs, namely diclofenac sodium and indomethacin, are recommended, but there are some other drugs which have some potential benefits in reducing the incidence of post-ERCP pancreatitis. Endoscopic preventive measures include cannulation(wire guided) and pancreatic stenting, while the adoption of the early pre-cut technique is still arguable. This review will attempt to present and discuss different ways of preventing post-ERCP pancreatitis.Goran Hauser Marko Milosevic Davor Stimac Enver Zerem Predrag Jovanovi?

4Nonalcoholic fatty liver disease and liver transplantation-Where do we stand?显示文摘Nonalcoholic fatty liver disease/nonalcoholic steatohepatitis(NAFLD/NASH) is a challenging and multisystem disease that has a high socioeconomic impact. NAFLD/NASH is a main cause of macrovesicular steatosis and has multiple impacts on liver transplantation(LT), on patients on the waiting list for transplant, on posttransplant setting as well as on organ donors. Current data indicate new trends in the area of chronic liver disease. Due to the increased incidence of metabolic syndrome(Met S) and its components, NASH cirrhosis and hepatocellular carcinoma caused by NASH will soon become a major indication for LT. Furthermore, due to an increasing incidence of Met S and, consequently, NAFLD, there will be more steatotic donor livers and less high quality organs available for LT, in addition to a lack of available liver allografts. Patients who have NASH and are candidates for LT have multiple comorbidities and are unique LT candidates. Finally, we discuss long-term grafts and patient survival after LT, the recurrence of NASH and NASH appearing de novo after transplantation. In addition, we suggest topics and areas that require more research for improving the health care of this increasing patient population.Ivana Mikolasevic Tajana Filipec-Kanizaj Maja Mijic Ivan Jakopcic Sandra Milic Irena Hrstic Nikola Sobocan Davor Stimac Patrizia Burra 2018World Journal of Gastroenterology2018,24,14:14
5Endoscopic retrograde cholangiopancreatography-induced and non-endoscopic retrograde cholangiopancreatographyinduced acute pancreatitis:Two distinct clinical and immunological entities?显示文摘Acute pancreatitis(AP) is common gastrointestinal disease of varied aetiology. The most common cause of AP is gallstones, followed by alcohol abuse as an independent risk factor. With the increased need for invasive techniques to treat pancreatic and bile duct pathologies such as endoscopic retrograde cholangiopancreatography(ERCP), AP has emerged as the most frequent complication. While severe AP following ERCP is rare(0.5%), if it does develop it has a greater severity index compared to non-ERCP AP. Development of a mild form of AP after ERCP is not considered a clinically relevant condition. Differences in the clinical presentation and prognosis of the mild and severe forms have been found between non-ERCP AP and postendoscopic pancreatitis(PEP). It has been proposedthat AP and PEP may also have different immunological responses to the initial injury. In this review, we summarise the literature on clinical and inflammatory processes in PEP vs non-ERCP AP.Ivana Plavsic Ivana Zitini Ivana Mikolasevic Goran Poropat Goran Hauser 2018World Journal of Gastrointestinal Endoscopy2018,10,10:14
6Local Proinflammatory Effects of Repeated Skin Exposure to Warfarin, An Anticoagulant Rodenticide in Rats显示文摘Objective: To evaluate the effects of epicutaneous application of anticoagulant warfarin, by examining the presence of tissue injury and immune/inflammatory activity in exposed skin. Methods: Rats were exposed to warfarin by applying 10 μg of warfarin‐sodium to 10‐12 cm 2 skin (range 0.8‐1 μg per 1 cm 2 ) for 3 consecutive days. Tissue injury was evaluated by lipid peroxidation, histomorphological changes and signs of reparative activity in skin. T cell infiltration and selected aspects of epidermal cell activity were examined as indicators of immune/inflammatory skin response to warfarin application. Results: Repeated warfarin application exerted no effect on skin metabolic viability, but resulted in tissue injury (increased malondialdehyde, MDA, production, evident histo‐morphological changes in epidermis and dermis depicting cell injury and death). Increased numbers of proliferating cell nuclear antigen (PCNA + ) cells indicated reparative processes in injured skin. Infiltration of CD3 + cells (T lymphocytes) along with the increased production of tumor necrosis factor‐α (TNF‐α) by epidermal cells from warfarin‐treated skin and their co‐stimulatory effect in an in vitro T‐cell activation assay demonstrated immunomodulatory effects of epicutaneous warfarin. Conclusion: Presented data have documented tissue damage associated with immune/ inflammatory activity in skin exposed to warfarin. Observed effects are relevant to immunotoxic potential of this anticoagulant in settings of external exposure.Aleksandra POPOV Ivana MIRKOV Lidija ZOLOTAREVSKI Milena JOVIC Sandra BELIJ Dragan KATARANOVSKI Milena KATARANOVSKI 2011Biomedical and Environmental Sciences2011,24,2:13
7Clinical implications of hepatitis B virus mutations:Recent advances显示文摘Hepatitis B virus(HBV)infection is a major cause of acute and chronic hepatitis,and of its long-term complications.It is the most variable among DNA viruses,mostly because of its unique life cycle which includes the activity of error-prone enzyme,reverse transcriptase,and the very high virion production per day.In last two decades,numerous research studies have shown that the speed of disease progression,reliability of diagnostic methods and the success of antiviral therapy and immunization are all influenced by genetic variability of this virus.It was shown that mutations in specific regions of HBV genome could be responsible for unwanted clinical outcomes or evasion of detection by diagnostic tools,thus making the monitoring for these mutations a necessity in proper evaluation of patients.The success of the vaccination programs has now been challenged by the discovery of mutant viruses showing amino acid substitutions in hepatitis B surface antigen(HBsAg),which may lead to evasion of vaccine-induced immunity.However,the emergence of these mutations has not yet raised concern since it was shown that they develop slowly.Investigations of HBV genetic variability and clinical implications of specific mutations have resulted in significant advances over the past decade,particularly in regard to management of resistance to antiviral drugs.In the era of drugs with high genetic barrier for resistance,on-going monitoring for possible resistance is still essential since prolonged therapy is often necessary.Understanding the frequencies and clinical implications of viral mutations may contribute to improvement of diagnostic procedures,more proper planning of immunization programs and creating the most efficient therapeutic protocols.Ivana Lazarevic 2014World Journal of Gastroenterology2014,20,24:12

9Treatment approach to type 2 diabetes:Past,present and future显示文摘Type 2 diabetes mellitus(DM) is a lifelong metabolic disease, characterized by hyperglycaemia which gradually leads to the development and progression of vascular complications. It is recognized as a global burden disease, with substantial consequences on human health(fatality) as well as on health-care system costs. This review focuses on the topic of historical discovery and understanding the complexity of the disease in the field of pathophysiology, as well as development of the pharmacotherapy beyond insulin. The complex interplay of insulin secretion and insulin resistance developed from previously known 'ominous triumvirate' to 'ominous octet' indicate the implication of multiple organs in glucose metabolism. The pharmacological approach has progressed from biguanides to a wide spectrum of medications that seem to provide a beneficial effect on the cardiovascular system. Despite this, we are still not achieving the target treatment goals. Thus, the future should bring novel antidiabetic drug classes capable of acting on several levels simultaneously. In conclusion, given the raising burden of type 2 DM, the best present strategy that could contribute the most to the reduction of morbidity and mortality should be focused on primary prevention.Kristina Blaslov Fran Stjepan Naranda Ivan Kruljac Ivana Pavlic Renar 2018World Journal of Diabetes2018,9,12:7
10How to treat an extensive form of primary intestinal lymphangiectasia?显示文摘We report a case of a 42-year-old man with a rare disorder known as primary intestinal lymphangiectasia,which is characterized by dilated intestinal lymphatics that lead to the development of protein-losing enteropathy. The patient presented with a grand mal seizure caused by malabsorption-derived electrolytes and a protein disorder. Signs of the disease, including chronic diarrhea and peripheral edema, manifested10 years ago, but a diagnosis was never made. The diagnosis was suspected because of the clinical manifestations, laboratory tests, imaging and endoscopic findings. Hyperemic and edematous mucosa of the small intestine corresponded to scattered white spots with dilated intestinal lymphatics and whitish villi in the histological specimen of the biopsied jejunal mucosa.Although numerous therapeutic strategies are available,only octreotide therapy proved to be an effective means of therapeutic resolution in this patient. Although the patient had a partial remission following the use of a slow release formula of octreotide, his prognosis, clinical course, and future treatment challenges are yet to be determined.Rosana Troskot Dragan Jurcic Ante Bilic Marija Gomercic Palcic Stanko Tezak Ivana Brajkovic 2015World Journal of Gastroenterology2015,21,23:6

12Inactive matrix Gla protein is elevated in patients with inflammatory bowel disease显示文摘BACKGROUND Matrix Gla protein(MGP)is a vitamin K dependent peptide which has an established role in suppression of vascular calcification.Recent studies have pointed to a possible link between immunomodulatory effect of MGP and inflammatory bowel disease(IBD).AIM To compare plasma levels of dephosphorylated and uncarboxylated MGP(dpucMGP)between IBD patients and controls.METHODS This cross-sectional study was conducted on 70 patients with IBD(30 patients with ulcerative colitis and 40 patients with Crohn’s disease)and 60 age and gender matching healthy controls.Plasma dp-ucMGP levels were analyzed from blood samples by CLIA method using IDS-iSYS InaKtif MGP(Immunodiagnostic Systems,Frankfurt,Germany)according to the manufacturer's instructions.fecal calprotectin(FC)levels were determined from stool samples by turbidimetric immunoassay method using Bühlmann fecal calprotectin turbo assay(Bühlmann Laboratories Aktiengesellschaft,Schonenbuch,Switzerland).Other parameters were analyzed according to the standard laboratory procedures.RESULTS Plasma levels of dp-ucMGP were significantly higher in patients with IBD compared to the healthy control group(629.83±124.20 pmol/mL vs 546.7±122.09 pmol/mL,P<0.001),and there was no significant difference between patients with Crohn’s disease and patients with ulcerative colitis(640.02±131.88 pmol/mL vs 616.23±113.92 pmol/mL,P=0.432).Furthermore,a significant positive correlation of plasma dp-ucMGP levels was found with both FC levels(r=0.396,P<0.001)and high sensitivity C-reactive protein(hsCRP)levels(r=0.477,P<0.001).Moreover,in the total study population a significant positive correlation was found between dp-ucMGP with age(r=0.210,P=0.016)and waist circumference(r=0.264,P=0.002).Multiple linear regression analysis showed that dp-ucMGP levels retained significant association with FC(β±SE,0.06±0.02,P=0.003).CONCLUSION Study results support experimental data of MGP immunomodulatory IBD effect and indicate potential involvement in the pathophysiology of the disease,and possibly extraintestinal manifestations.Darko Brnic Dinko Martinovic Piero Marin Zivkovic Daria Tokic Marino Vilovic Doris Rusic Ivana Tadin Hadjina Christian Libers Sandro Glumac Daniela Supe-Domic Ante Tonkic Josko Bozic 2020World Journal of Gastroenterology2020,26,32:5
13Current concept in the diagnosis,treatment and rehabilitation of patients with congestive heart failure显示文摘Heart failure(HF)is a major public health problem with a prevalence of 1%-2%in developed countries.The underlying pathophysiology of HF is complex and as a clinical syndrome is characterized by various symptoms and signs.HF is classified according to left ventricular ejection fraction(LVEF)and falls into three groups:LVEF≥50%-HF with preserved ejection fraction(HFpEF),LVEF<40%-HF with reduced ejection fraction(HFrEF),LVEF 40%-49%-HF with mid-range ejection fraction.Diagnosing HF is primarily a clinical approach and it is based on anamnesis,physical examination,echocardiogram,radiological findings of the heart and lungs and laboratory tests,including a specific markers of HF-brain natriuretic peptide or N-terminal pro-B-type natriuretic peptide as well as other diagnostic tests in order to elucidate possible etiologies.Updated diagnostic algorithms for HFpEF have been recommended(H2FPEF,HFA-PEFF).New therapeutic options improve clinical outcomes as well as functional status in patients with HFrEF(e.g.,sodium-glucose cotransporter-2-SGLT2 inhibitors)and such progress in treatment of HFrEF patients resulted in new working definition of the term“HF with recovered left ventricular ejection fraction”.In line with rapid development of HF treatment,cardiac rehabilitation becomes an increasingly important part of overall approach to patients with chronic HF for it has been proven that exercise training can relieve symptoms,improve exercise capacity and quality of life as well as reduce disability and hospitalization rates.We gave an overview of latest insights in HF diagnosis and treatment with special emphasize on the important role of cardiac rehabilitation in such patients.Ivana Sopek Merkas Ana Marija Sliskovic Nenad Lakusic 2021World Journal of Cardiology2021,13,7:5
14Sodium-glucose cotransporter 2 inhibitors’ mechanisms of action in heart failure显示文摘Three major cardiovascular outcome trials(CVOTs)with a new class of antidiabetic drugs-sodium-glucose cotransporter 2(SGLT2)inhibitors(EMPAREG OUTCOME trial with empagliflozin,CANVAS Program with canagliflozin,DECLARE-TIMI 58 with dapagliflozin)unexpectedly showed that cardiovascular outcomes could be improved possibly due to a reduction in heart failure risk,which seems to be the most sensitive outcome of SGLT2 inhibition.No other CVOT to date has shown any significant benefit on heart failure events.Even more impressive findings came recently from the DAPA-HF trial in patients with confirmed and well-treated heart failure:Dapagliflozin was shown to reduce heart failure risk for patients with heart failure with reduced ejection fraction regardless of diabetes status.Nevertheless,despite their possible wide clinical implications,there is much doubt about the mechanisms of action and a lot of questions to unravel,especially now when their benefits translated to nondiabetic patients,rising doubts about the validity of some current mechanistic assumptions.The time frame of their cardiovascular benefits excludes glucoselowering and antiatherosclerotic-mediated effects and multiple other mechanisms,direct cardiac as well as systemic,are suggested to explain their early cardiorenal benefits.These are:Anti-inflammatory,antifibrotic,antioxidative,antiapoptotic properties,then renoprotective and hemodynamic effects,attenuation of glucotoxicity,reduction of uric acid levels and epicardial adipose tissue,modification of neurohumoral system and cardiac fuel energetics,sodiumhydrogen exchange inhibition.The most logic explanation seems that SGLT2 inhibitors timely target various mechanisms underpinning heart failure pathogenesis.All the proposed mechanisms of their action could interfere with evolution of heart failure and are discussed separately within the main text.Petra Grubić Rotkvić Maja Cigrovski Berković Nikola Bulj Luka Rotkvić Ivana Ćelap 2020World Journal of Diabetes2020,11,7:5
15P92抗蠕变钢管微观组织对持久性能的影响显示文摘P92钢管的生产旨在获得回火马氏体的微观组织;但在某些条件下,尤其在生产厚壁钢管时,可能会形成少量的铁素体。对此,本文对众多P92钢试样进行了大量深入的微观组织分析,并研究了回火马氏体基体中存在少量铁素体组织对其短期和持久性能的影响。发现P92钢管中可能存在成因和性能不同的2种铁素体组织;在钢液凝固过程中,如果铁素体和奥氏体形成元素未保持适当的平衡,稳定铁素体(也称δ-铁素体)会形成并保留在冷却至室温后的微观组织中;在热处理过程中,如果从奥氏体化温度冷却的速度较慢,奥氏体会分解成铁素体和碳化物,形成另一种形式的铁素体;对不含铁素体和含铁素体体积分数为8%的试样进行对比分析,未观察到P92钢短期和持久性能上的明显变化,如进行了持续时间达70 000h的蠕变性能试验,蠕变断裂数据处在基于ECCC评定数据曲线的分散带内。最后提出采用比较法测定无缝钢管和锻件中铁素体组织含量的指导方法,目前已经作为VdTV数据表,得到了确认和公布。Vida Knezevic Bruno Lefebvre Ivana Parezanovic 2016热力发电2016,45,3:5

18Subchronic Oral Cadmium Exposure Exerts both Stimulatory and Suppressive Effects on Pulmonary Inflammation/Immune Reactivity in Rats显示文摘Objective The aim of this study is to investigate the effects of oral cadmium(Cd) ingestion on the pulmonary immune response. Methods Determination of Cd content in lungs and histopathological evaluation of the tissue was performed in rats following 30-day oral Cd administration(5 and 50 mg/L). Antioxidant enzyme defense(superoxide dismutase and catalase), cell infiltration, and production of tumor necrosis factor(TNF) and interferon(IFN)-γ, as well as the activity of myeloperoxidase(MPO), nitric oxide(NO), and various cytokines [interleukin(IL)-1β, IL-6, IL-10, and IL-17] were investigated. Results Cd caused tissue damage and cell infiltration in the lungs, and this damage was more pronounced at higher doses. Cd deposition resulted in lung inflammation characterized by a dose-dependent IL-1β increase in lung homogenates, increased TNF levels at both doses, and IL-6 stimulation at low doses with inhibition observed at higher doses. Cd exerted differential effects on lung leukocytes isolated by enzyme digestion, and these effects were characterized by a lack of change in the production of reactive oxygen and nitrogen species, an inhibition of IL-1β and TNF, and stimulation of MPO and IFN-γ. The higher capacity of Cd-exposed lung cells to respond to the opportunistic pathogen Staphylococcus epidermidis was demonstrated in vitro. Conclusion The potential of ingested Cd to exert both proinflammatory and immunosuppressive effects on pulmonary tissue inflammation and immune reactivity highlights the complex immunomodulatory actions of this metal.KULAS Jelena NINKOV Marina TUCOVIC Dina POPOV Aleksandrov Aleksandra UKROPINA Mirela CAKIC MILOSEVIC Maja MUTIC Jelena KATARANOVSKI Milena MIKROV Ivana 2019Biomedical and Environmental Sciences2019,32,7:4
