PRELIMINARY ANALYSIS OF CO-AUTHORSHIP NETWORKS ATTHE UNIVERSITY OF RIJEKA

U radu je opisana preliminarna analiza mreža koautorstva Sveučilišta u Rijeci za četiri odabrane sastavnice. Mreža koautorstva prikazuje suradnju znanstvenika u objavljivanju znanstvenih publikacija. Konstruira se tako da je svaki znanstvenik čvor, a veza između dvaju čvorova postoji ako su ta dva znanstvenika objavila zajedničku publikaciju. Težina veze predstavlja broj objavljenih publikacija dvaju znanstvenika. Cilj je analizirati i usporediti suradnju na nekoliko različitih sastavnica Sveučilišta u Rijeci. Za potrebe analize korištene su metode analize kompleksnih mreža. U prvoj fazi eksperimenta podaci su prikupljeni s mrežnih stranica Hrvatske znanstvene bibliografije (CROSBI) i obrađeni te formatirani u odgovarajući oblik. U drugoj fazi eksperimenta konstruirane su mreže koautorstva i provedena je analiza podataka. Prvo su analizirane i uspoređene numeričke vrijednosti globalnih mjera mreža. Nakon toga je prikazana analiza i vizualizacija zajednica na središnjoj razini mreže. Na kraju su na lokalnoj razini analizirani centralni čvorovi u mrežama primjenom triju različitih lokalnih mjera centralnosti. Pokazalo se da promatrane mreže imaju neka zajednička globalna svojstva, no rezultati ukazuju i na to da se sastavnice prilično razlikuju u broju i strukturi zajednica. Analizom na lokalnoj razini također je ustanovljeno da broj ostvarenih zajedničkih publikacija značajno varira po sastavnicama.In this paper we describe preliminary co-authorship network analysis performed for the four constituents of the University of Rijeka. Co-authorship network describes scientific collaboration among scientists. It is constructed in a way that each scientist is represented as a node and a link between two nodes is constructed if these two scientists collaborate on the same scientific publication. The weight on the link represents the number of scientific publications. The goal of this experiment has been to analyse and compare scientific collaboration among several constituents of the University of Rijeka. For this experiment the methods of complex networks analysis have been used. In the first phase of the experiment the dataset from web pages: Croatian Scientific Bibliography (CROSBI) is collected. In the second phase of the experiment five networks are constructed and analysed. The numeric values of the global network measures are analysed first. After that, the communities at the mesoscale network level are identified and visualised. At the end, central nodes are found (according to the three centrality measures). It is shown that all networks have similar global properties. However, there are differences between networks in the community structure. According to the local-level analysis, the number of publications among constituents vary substantially

Cognitive Functions in Combat Posttraumatic Stress Disorder

Posttraumatic stress disorder (PTSD) is associated with changes in cognitive functions. The aim of the study was to investigate differences in cognitive abilities between PTSD patients and healthy controls. As PTSD is often accompanied by comorbidity, the PTSD patients with comorbid diagnoses were also included in our study. The study participants in¬cluded 254 Croatian combat veterans (60 PTSD and 194 PTSD plus comorbidity) and control group of 125 healthy Cro¬atian military and civilian pilots. The diagnosis of PTSD was made by clinical scale for PTSD assessment (CAPS), while cognitive abilities were measured by Wechsler intelligence scale (WAIS-III-R) and Rey test (ROCFT). The study results have confirmed that there is a significant difference in cognitive functions between the PTSD patients and healthy controls regarding age and education. The PTSD patients (PTSD only and PTSD with comorbidity) have shown lower general intellectual abilities, reduced capacity of working, numerical and visual memory, and decreased executive functions when compared to healthy controls. These results are an additional contribution to a better understanding and determination of changes in cognitive functions that occur in combat PTSD as a result of traumatic stress

CONSERVATION AND RESTORATION OF THE SCULPTURES FROM THE FACADE OF THE PARISH CHURCH OF ST. PETER IN SUPETAR ON THE ISLAND OF BRAČ

U radu je obrađen tijek i metodologija konzervatorsko-restauratorskog postupka na kamenim skulpturama sa glavnog pročelja župne crkve sv. Petra u Supetru na Braču. Opisan je tretman površinskih oštećenja, skrama, mehaničkih lomova i potpune degradacije forme i dijelova skulpture kao i način njihova spajanja i rekonstrukcije.Construction of the parish church of St. Peter in Supetar began in the 16th century, upon the remains of an early-Christian basilica. The original church burned down in a fire in 1792, and the citizens of Supetar soon began work on a new one. By the end of the 19th century, the church had been expanded several times, but its western facade, decorated with stone sculptures (the Holy Father and two angels, an angel relief and six vases), remained unchanged. The main problem with these pieces was the possibility that they would fall from their place on the façade, due to the inadequate manner in which they were fastened to their bases, thus endangering the faithful and passers by. The sculptures were taken down and transported to the "Neir" company workshop in Split, where they underwent conservation and restoration procedures. By studying the observed state of the pieces, various forms of damage and impurities in the stone were observed, as a result of environmental influences and natural material degradation. The surface of these sculptures was extremely cracked and eroded by water, as well as the application of inadequate cleaning methods which were used in the past. Corrosion on the iron elements that were used to fasten the pieces to the church\u27s facade caused the stone to break in places, so certain pieces were irrevocably lost. These spots were reconstructed using mortar with a base of gray portland cement, which is inappropriate for the restoration of stone as it contains large quantities of harmful salts which seep into the structure of the material when exposed to moisture, thus contaminating it. By combining the results of preliminary conservation and restoration research, which includes a detailed study of the observed state of the pieces, with diagnostic testing of the concentration of harmful salts in the stone, a course was set for the conservation and restoration effort. This includes removing the impurities, desalinization, replacing the iron elements with stainless steel splints, applying a hydrophobic coating and properly installing the pieces, so as to prevent or at least slow down any harmful processes, and preserve the pieces as well as possible

Management of fetal supraventricular tachyarrhythmia - case report

The conduction system of the fetal heart is defined by the16th week of gestation when it matures and normally produces a regular rhythm and rate between 110 and 160 beats per minute (bpm) for the remainder of the pregnancy. Deviations from these parameters are fetal arrhythmias. They are diagnosed in 2% of unselected pregnancies. They are mostly benign and transient but some of them are persistent and associated with structural defects or can cause heart failure, fetal hydrops and intrauterine death. Routine prenatal care includes screening for fetal arrhythmias in the second and third trimester with fetal ultrasound examinations which include a view of the four cardiac chambers and both ventricular outflow tracts. The fetal outcomes are improved upon appropriate antepartum diagnosis and care. Here we present a pregnancy and multidisciplinary management, prenatal evaluation and intervention with maternal transplacental treatment of a 28-year-old female, gravida II, para II, in 28+5 weeks of gestation with fetal arrhythmia, in tertiary university hospital. She had a history of previous caesarean section, in the 40th week of gestation due to an infection of the synus pylonidalis. We confirmed suspected fetal arrhythmia as supraventricular tachyarrhythmia without fetal hydrops, based on the ultrasound doppler M mode imaging, and started transplacental administration of antiarrhythmyc agent, digoxin. It has been considered the first line agent for treatment of fetal supraventricular tachycardia but higher maternal doses are required to maintain a therapeutic serum level. We converted fetal heartbeat into normal sinus rhythm after three days of administration of digoxin. We continued to monitor the fetus once a week with controlling levels of digoxin and electrolytes in maternal blood until the end of the pregnancy at 38+6 weeks of gestation

Diskordantni rast u dikorionskih blizanaca i rizik prijevremenog porođaja

The aim was to determine whether discordant twin growth has an impact on preterm birth in dichorionic pregnancies. This retrospective study included dichorionic twin pregnancies in the period from January 1, 2013 to December 31, 2015. The following variables were investigated: maternal age (years), parity, body mass index (kg/m2), week (≤366/7 and ≥37) and mode of delivery (vaginal and cesarean section), birth weight (grams) and Apgar score (≤7, 8-10). Discordant twin growth in dichorionic pregnancies was found to be associated with preterm birth (χ2=4.74; p=0.03) but had no impact on the mode of delivery (χ2=0.119; p=0.73). There was a statistically significant difference in the rate of small for gestational age (SGA) neonates (χ2=16.4556; p=0.000267) and Apgar score (χ2=7.9931; p<0.05) between the study groups. Mode of conception in dichorionic pregnancies was not a risk factor for preterm delivery (χ2=1.417; p=0.23). In conclusion, discordant twin growth in dichorionic pregnancies is a risk factor for preterm delivery and has no impact on the mode of delivery but has an impact on the rate of SGA and Apgar score.Cilj istraživanja je bio ustanoviti ima li diskordantni rast blizanaca u dikorionskim blizanačkim trudnoćama utjecaja na pojavnost prijevremenog porođaja. U studiju su uključene dikorionske blizanačke trudnoće u razdoblju od 1. siječnja 2013. do 31. prosinca 2015. Istraživane varijable su bile majčinska dob (godine), paritet, indeks tjelesne mase (kg/m2), način po-rođaja (vaginalno i carski rez), porođajna masa (grami) i zbroj APGAR (≤7, 8-10). U blizanačkim trudnoćama s diskordantnim rastom bila je veća učestalost prijevremenog porođaja (χ2=4,74; p=0,03), ali nije bilo razlike u načinu dovršetka trudnoće ­između istraživanih skupina (χ2=0,119; p=0,73). Utvrđena je statistički značajna razlika u pojavnosti hipotrofične djece (χ2=16,4556; p=0,000267) i zbroju APGAR (χ2=7,9931; p<0,05) između istraživanih skupina. Način zanošenja u dikorionskim trudnoćama nije bio činitelj rizika za prijevremeni porođaj u istraživanim skupinama (χ2=1,417; p=0,23). Zaključno, diskordantni rast blizanaca u dikorionskim trudnoćama predstavlja činitelj rizika za prijevremeni porođaj, hipotrofiju novorođenčadi i niži zbroj APGAR, ali nema utjecaja na način dovršetka trudnoće

Civilian Casualty of Landmine – The Pattern of Injury and Course of Treatment

In Croatia civilian casualties of landmine explosions 20 years after the war are still present. The presented case is a 42 years old housewife who sustained multiple body and face injuries while cleaning her courtyard. The treatment was performed in several steps. Initial treatment included thoracic drainage, abdominal surgery and the rigid fixation of the mandibular defect. Four months later mandibular reconstruction with free flap was performed. After plate removal the restoration of dental status was performed by partial denture although the application of dental implants would be superior. The optimal rehabilitation was omitted because heath insurance policy does not provide the reimbursement of dental implants costs for outpatients even in cases of landmine victims traumatic teeth loss

PSYCHOLOGICAL FACTORS IN EXPERIENCE OF PAIN DURING CHILDBIRTH

Aim: Pain during delivery is unique because it is accompanied by powerful emotions. Emotions that occur in women during labor and delivery are closely tied to upbringing and culture in which they were raised and consequently with the sensation of experienced pain. According to the Melzack-Wall Theory of Pain, general mood is directly related to the intensity and quality of pain and it is therefore justifiable to presuppose that certain psychosocial factors will be linked with the intensity and quality of pain experienced during childbirth. (Melzack et al., 1981). We endeavored to show the effect of psychosocial factors that influence the intensity and quality of labor pain. Methods: Data were collected in a sample of 176 parturient women who delivered without Cesarean sections or epidural anesthesia. The intensity and quality of pain were obtained through the administration of the McGill Pain Questionnaire - Short Form. Psychosocial factors included: number of births, presence of partner, self-evaluation of knowledge of physio-anatomical aspects of birth and the completion of a pregnancy course. Results: Labor and delivery pain is of high intensity and the quality of pain is most frequently characterized as smarting, cramping, exhausting, and sharp. The presence of a partner and the completion of a pregnancy course is exercised by a small number of parturients. Self-evaluation of preexisting knowledge of physio-anatomical aspects of delivery is predictive of the affective component of intensity of childbirth pain. Conclusion: Psychosocial factors have been shown as significant for the intensity and quality of experienced childbirth pain

Postoji li razlika u perinatalnom ishodu jednoplodnih i blizanačkih trudnoća nakon medicinski potpomognute oplodnje

The aim of the study was to compare perinatal outcome of singleton and twin pregnancies conceived after assisted reproductive technologies (ART ). This retrospective study included singleton and twin pregnancies conceived after ART in the period from January 1, 2007 until December 31, 2008. The study variables were maternal age (years), parity, body mass index (BMI; kg/m2), week (≤366/7 and ≥37) and mode of delivery (vaginal and cesarean section), birth weight (grams) and APGAR score (≤7; 8-10). During the study period, there were 195 pregnancies after ART that fulfilled inclusion criteria. We found no between-group difference in parity (χ2=0.0133; P=0.9081), but such difference was found in mean age (t=2.0486; p=0.0419) and BMI (χ2=31.038; P=0.001). A statistically significant difference was recorded in preterm delivery rate (χ2=25.539; P=0.001), average duration of pregnancy (t=12.8591; p=0.001), average birth weight (t=10.5446; P=0.001) and mode of delivery (χ2=13,691; P=0.001). A statistically significant difference was found in low birth weight babies (χ2=102.02; P=0.001) and APGAR score (χ2=19.96; P=0.001), but there was no difference in the prevalence of small for gestational age babies (χ2=0.90629; P=0.635). In conclusion, this study indicated the perinatal outcome after ART to be considerably poorer in twins than in singletons.Cilj ove studije bio je istražiti razliku u perinatalnom ishodu jednoplodnih i blizanačkih trudnoća nakon medicinski potpomognute oplodnje (MPO). Ispitana je medicinska dokumentacija jednoplodnih i blizanačkih trudnoća u žena koje su rodile živorođenu djecu nakon MPO u dvogodišnjem razdoblju u Klinici za ženske bolesti i porode, KBC Split, od 1. siječnja 2007. do 31. prosinca 2008. godine. Istraživane varijable bile su dob, paritet, indeks tjelesne mase (kg/m2), navršeni tjedan poroda (prijevremeni ≤366/7 i terminski ≥37), način dovršetka porođaja (vaginalno i carski rez), porođajna masa djeteta (grami), trofičnost djeteta (hipertrofično, eutrofično i hipotrofično) i APGAR zbroj novorođenčeta (≤7, 8-10). U promatranom razdoblju 195 trudnica je rodilo nakon neke od metoda MPO. Između rodilja s jednoplodnom i blizanačkom trudnoćom koje su zanijele nekom metodom MPO nije bilo razlike u paritetu (χ2=0,0133; P=0,9081), dok su razlike pronađene u prosječnoj dobi (t=2,0486; p=0,0419) i indeksu tjelesne mase (χ2=31,038; p=0,001). Statistički značajna razlika nađena je u učestalosti prijevremenog poroda (χ2=25,539; P=0,001), prosječnom trajanju trudnoće (t=12,8591; p=0,001) i prosječnoj porodnoj masi djece (t=10,5446; P=0,001). Blizanačke trudnoće u usporedbi s jednoplodnim trudnoćama nakon MPO češće se dovršavaju carskim rezom (χ2=13,691; P=0,001). Pronađena je statistički značajna razlika između istraživanih skupina u rađanju djece niske porodne mase (<2500 g) (χ2=102,02; P=0,001) i APGAR zbroju novorođenčadi (χ2=19,96; P=0,001). Nije bilo statistički značajne razlike u učestalosti rađanja hipotrofične djece između istraživanih skupina (χ2=0,90629; P=0,635). U zaključku, perinatalni ishod nakon MPO je lošiji u blizanačkih nego u jednoplodnih trudnoća

Delivery of hypertrophic term newborns in Split Clinical Hospital Center

Cilj rada: Istražiti učestalost, načine i čimbenike rađanja hipertrofične novorođenčadi u Klinici za ženske bolesti i porode KBC-a Split tijekom 2008. i 2009. godine. Materijali i metode: U istraživanje su uključene sve rodilje koje su u razdoblju od 2008. do 2009. godine rodile hipertrofičnu novorođenčad (n = 792). Iz istraživanja su isključene višeplodne trudnoće, te mrtvorođena i malformirana novorođenčad. Kontrolnu skupinu čine sljedeća dva porođaja terminske eutrofične vorođenčadi u promatranom razdoblju. Podaci su prikupljeni popisnom metodom iz pisanih rađaonskih protokola Klinike za ženske bolesti i porode KBC-a Split. Rezultati: U promatranom dvogodišnjem razdoblju rođeno je 8,76% hipertrofične novorođenčadi. Carskim rezom rođeno je 18,3% hipertrofične novorođenčadi i 15,1% eutrofične novorođenčadi (P = 0,072). Majke hipertrofične novorođenčadi su češće rađale uz pomoć epiziotomije (P = 0,002). Hipertrofična novorođenčad imala su statistički značajno veću (22,9%) prosječnu porođajnu težinu (P < 0,001), za 4,9% veću duljinu (P < 0,001), te za 6,3% viši ponderalni indeks u odnosu na eutrofičnu novorođenčad (P < 0,001). Učestalost gestacijskog dijabetesa melitusa bila je statistički značajno veća u majki hipertrofične novorođenčadi (P = 0,031). Zaključak: Fetalna hipertrofija je stanje povećanog perinatalnog rizika. Ultrazvukom prepoznat ubrzani fetalni rast može usmjeriti način daljnjega nadzora trudnoće, a neposredno prije poroda pomoći u izboru načina rađanja i vođenja porođaja.Aim: To investigate the frequency, mode of delivery and perinatal factors of hypertrophic term newborns at the Department of Gynaecology and Obstetrics, Split University Hospital in a two year period (2008- 2009). Methods: The study included all parturient women who gave birth to hypertrophic term infants between 2008 and 2009 (n = 792). Multiple pregnancies, stillborns and malformed newborns were excluded from the study. The control group consisted of two term births of eutrophic newborns following each delivery from the study group. Clinical data were gathered from the birth protocol of the Department of Gynaecology and Obstetrics, Split University Hospital. Results: In the analysed period 8.76% newborns were hypertrophic. Caesarean section was performed in 18.3% hypertrophic and 15.1% eutrophic newborns (P = 0.072). An episiotomy was preformed more frequently in women with hypertrophic newborns (P = 0.002). Hypertrophic newborns had 22.9% significantly higher average birth weight (P < 0.001), 4.9% average higher length (P < 0.001) and 6.3% higher average ponderal index (P < 0,001). The frequency of gestational diabetes mellitus was significantly higher in women with hypertrophic newborns (P = 0.031).Conclusion: Fetal hypertrophy is a state of increased perinatal risk. Ultrasound detected accelerated fetal growth can help in directing a way of further pregnancy monitoring, and immediately before delivery in selection of birth mode and conduction of delivery
