Macrophage polarization is a process when macrophage expresses different functional programs in response to microenvironmental signals and two extreme forms exist; M1 and M2 macrophages. M1 macrophages are highly microbicidal and anticancer with enhanced ability to kill and phagocytose pathogens, upregulate pro-inflammatory cytokines and reactive molecular species, and present antigens; M2 macrophages and the related tumour associated macrophages (TAMs) regulate tissue remodelling and promote tissue repair and angiogenesis and can amplification of metabolic pathways that can suppress adaptive immune responses. It is demonstrated that ROS production, critical for the activation and functions of M1 macrophages, is necessary for the differentiation of M2 macrophages and TAMs, and that antioxidant therapy blocks TAMs differentiation and tumorigenesis in mouse models of cancer. In order to study how caffeic acid (CA), a natural antioxidant, affects macrophage function, polarization, angiogenesis and tumour growth we injected mice with Ehrlich ascites tumour (EAT) cells and treated them for 10 days with CA in a dose of 40 and/or 80 mg kg−1. Macrophage polarization was further characterized by quantifying secreted pro- and anti-inflammatory cytokines, nitric oxide and arginase 1 activity. CA may increase the cytotoxic actions of M1 macrophages and inhibit tumour growth; inhibitory activity on TAMs may be mediated through its antioxidative activity. Taken together, we conclude that the antitumour activity of CA was the result of the synergistic activities of different mechanisms by which CA acts on proliferation, angiogenesis, immunomodulation and survival. The continuous administration of CA efficiently blocked the occurrence of TAMs and markedly suppressed tumorigenesis in mouse cancer models. Targeting TAMs by antioxidants can be a potentially effective method for cancer treatment. © 2016 Elsevier Ireland Ltd

OBJECTIVE: To compare the efficacy of 4 dosage regimens of cetrorelix pamoate, a sustained release formulation that allows for more convenient dosing, in patients with symptomatic benign prostatic hyperplasia (BPH). Repeated dosing with cetrorelix acetate was shown to be active in the treatment of BPH symptoms. METHODS: Double-blind, randomized, multicenter study was undertaken among patients with International Prostate Symptom Score (IPSS) <13. After a single-blind placebo run-in phase of 4 weeks, treatment was administered at 2-week intervals as follows: 30 + 30 mg, 30 + 30 + 30 mg, 60 + 30, 60 + 60 mg cetrorelix pamoate, or matching placebo. Patients were followed-up for 28 weeks after randomization. RESULTS: A statistically significant overall difference was found with respect to the primary variable, the IPSS (P ≤.001). Optimal results, a 4-point improvement in IPSS in excess of the changes observed in the placebo group, were achieved with a starting dose of 60 mg cetrorelix pamoate followed by a dose of 30 mg 2 weeks later. In all dosage groups, the symptomatic improvement was paralleled by an increase in uroflow. There was a marked dissociation between only moderate and transient testosterone suppression and the persisting effects on BPH signs and symptoms. Tolerability was good at all cetrorelix dosages. CONCLUSIONS: Intramuscular injections of 60 and 30 mg of cetrorelix pamoate within 2 weeks provide rapid symptomatic improvements of BPH that are sustained for the following 6 months. © 2010 Elsevier Inc.

Toll-like receptor (TLR) 4 signaling pathway has been shown to support tumor cell growth in vitro and in vivo. Its stimulation on breast cancer cell lines induces β1 integrin and promotes tumor invasiveness. However, its role in predicting clinical behavior of tumor is not yet clarified. Therefore, we investigated TLR4 and β1 integrin expression on 133 primary breast cancer samples by immunohistochemistry and correlated it with overall survival and disease-free survival of patients as well as with clinicopathological characteristics of the tumor. We found higher β1 integrin expression in invasive lobular cancer in comparison with other tumor types. No significant association of TLR4 and β1 integrin expression with overall survival or disease-free survival was seen. Therefore, we conclude that expression of these markers is of biological interest but appears to be of little additional use as predictive clinical marker. © Springer Science+Business Media, LLC 2011.

The aim of this work was to evaluate to what extent the scope and content of information provided to patients is standardized across medical biochemistry laboratories in Croatia.Two on-line self-report surveys were sent out: Survey A regarding attitudes on importance of patient preparation and Survey B on the contents of patient preparation instructions.13/118 laboratories (11%) do not provide written instructions to patients on how to prepare for laboratory testing, and 36 (40%) do not include information about water intake in their instructions. Only half of laboratories provide instructions for prostate-specific antigen (53.8%), female sex hormones (53.7%) and therapeutic drug monitoring (TDM) (52.5%). Inadequate information about fasting status (55.0%) and 24 hour urine collection (77.9%) were frequent errors with high severity and were associated with the greatest potential to cause patient harm.Laboratory professionals in Croatia have a positive attitude towards the importance of patient preparation for laboratory testing. However, the information for laboratory testing is not standardized and frequently lacks guidance for tests related to TDM, coagulation and endocrinology. This study highlights the need for standardized, updated and evidence-based recommendations for patient preparation in order to minimize the risk for patients.

Recurrent epistaxis is a rare presentation of internal carotid artery C4/C5 segment pseudoaneurysm rupture. We describe a case of a traumatic internal carotid artery pseudo-aneurysm with recurrent epistaxis as a leading symptom that was finally managed with endovascular treatment with stent-assisted coil placement. Clopidogrel and acetylsalicylic acid orally were introduced in the therapy for further stent thrombosis prevention and epistaxis did not recur on six-month follow-up. Endovascular treatment with stent-assisted coil placement seems to be a good method for pseudo-aneurysm treatment while keeping the lumen of the parent artery patent.

To examine the informed consent process implementation and quality in Croatia using a specially developed instrument.A cross-sectional questionnaire study was conducted in 300 patients (response rate 73%) from six hospitals in Croatia, along with psychometric evaluation of the questionnaire.Signing the informed consent form was a formality for 64% of patients, 54% of patients did not give their written consent, and in 39% of cases physicians made treatment decisions by themselves. The overall informed consent process score was 4.060.60 (of 5.00). Physician-patient relationship score was 4.610.57, Verbal information 3.990.98, Decision making 3.940.75, and Written information 3.601.42. The overall Cronbachs alpha coefficient was 0.890. Significant correlations were found in relation to Physician-patient relationship and education levels (OR=0.43, 95% CI=0.18-0.99, p=0.048), and Verbal information and duration of health problems (OR=1.83, 95% CI=1.02-3.25, p=0.041).The developed questionnaire is reliable and valid. The informed consent process quality in Croatia was reasonably high, although insufficient and inadequate written materials represent a weak spot that require enhancement.The study contributes to the development of suitable measuring instrument for assessment of the informed consent process quality in clinical practice. The questionnaire could be of use in the hospital accreditation process.

Down syndrome (DS) is one of the most common chromosomal abnormalities among newborns. In recent years advances in perinatal and neonatal care have improved chance of survival for the children with DS. The objective of this Registry-Based study was to get more accurate data of DS prevalence with evaluation of antenatal screening, neonatal and maternal features among total births in Croatia from 2009 to 2012.We used retrospectively collected data for DS newborns from the medical birth database and perinatal mortality database for the period of 2009-2012. Differences between DS and the referent population for each year in quantitative measures were assessed with the independent t-test. Other differences in nominal and categorical values were analyzed with the chi-square test.The total prevalence for DS in the period of 2009-2012 was 7.01 per 10,000 births, while the live-birth prevalence was 6.49 per 10,000 births. The significant differences (p<0.05) between the DS and reference populations for each year were noticed for birth weight and length, gestational age, mother age, Apgar score of 6 after 5min and breastfeeding. Among newborns with DS, there were 64 (53.33%) males and 56 (46.67%) females versus 88,587 (51.76%) males and 82,553 (48.23%) females in the reference population. In the DS group compared to the reference population the mean birth weight was 2845 grams versus 3467 grams in males and 2834 grams versus 3329 grams in females, respectively, with a mean birth length of 47cm versus 50cm for both genders. The mean gestational age of the DS births was 37weeks and the mean age of the mothers was 32.6years, versus 39weeks and 29.1years, respectively, in the reference population. Only 68.3% of children with DS were breastfed from birth, compared with 94.72% of children in the reference population.The significant differences for neonatal and maternal features between DS and the referent population were found similar to other studies. The total prevalence of DS in Croatia in the period of 2009-2012 was lower than the previously estimated prevalence based on EUROCAT data. The establishment of a new national registry of congenital malformations covering 99% of all births in Croatia is necessary to improve the health and prosperity of children, adolescents and adults with DS in Croatia.

Nontuberculous mycobacteria (NTM) are opportunistic pathogens found in natural and human-engineered waters. In 2009, a relative increase in the isolation of Mycobacterium gordonae from pulmonary samples originating from General Hospital Zabok was noted by the National Mycobacteria Reference Laboratory. An epidemiological survey revealed a contamination of the cold tap water with M. gordonae and guidelines regarding sputum sample taking were issued. In addition, all incident cases of respiratory infection due to NTM reported from 2007 to 2012 at General Hospital Zabok were included in a retrospective review. Out of 150 individual NTM isolates, M. gordonae was the most frequently isolated species (n = 135; 90%) and none of the cases met the criteria of the American Thoracic Society for pulmonary NTM disease. While concomitant Mycobacterium tuberculosis infection was confirmed in only 6 (4%) patients, anti-tuberculosis treatment was initiated for a significant portion of patients (n = 64; 42.6%) and unnecessary contact tracing was performed. This study points out the need to enhance the knowledge about NTM in our country and indicates the importance of faster NTM identification, as well as the importance of good communication between laboratory personnel and physicians when evaluating the significance of the isolated NTM.

Perinatal mortality indicators are considered the most important measures of perinatal outcome. The indicators reliability depends on births and deaths reporting and recording. Many publications focus on perinatal deaths underreporting and misclassification, disabling proper international comparisons.Description of perinatal health care quality assessment key indicators in Croatia.Retrospective review of reports from all maternities from 2001 to 2014.According to reporting criteria for birth weight 500g, perinatal mortality (PNM) was reduced by 31%, fetal mortality (FM) by 32%, and early neonatal mortality (ENM) by 29%. According to reporting criteria for 1000g, PNM was reduced by 43%, FM by 36%, and ENM by 54%. PNM in 22 weeks (wks) gestational age (GA) was reduced by 28%, FM by 30%, and ENM by 26%. The proportion of FM at 32-36wks GA and at term was the highest between all GA subgroups, as opposed to ENM with the highest proportion in 22-27wks GA. Through the period, the maternal mortality ratio varied from 2.4 to 14.3/100,000 live births. The process indicators have been increased in number by more than half since 2001, the caesarean deliveries from 11.9% in 2001 to 19.6% in 2014.The comprehensive perinatal health monitoring represents the basis for the perinatal quality assessment.

Atherosclerosis is a complex multifocal arterial disease involving interactions of multiple genetic and environmental factors. Advances in techniques of molecular genetics have revealed that genetic ground significantly influences susceptibility to atherosclerotic vascular diseases. Besides further investigations of monogenetic diseases, candidate genes, genetic polymorphisms, and susceptibility loci associated with atherosclerotic diseases have been identified in recent years, and their number is rapidly increasing. This paper discusses main genetic investigations fields associated with human atherosclerotic vascular diseases. The paper concludes with a discussion of the directions and implications of future genetic research in arteriosclerosis with an emphasis on prospective prediction from an early age of individuals who are predisposed to develop premature atherosclerosis as well as to facilitate the discovery of novel drug targets.
