BioloŔke komplikacije cementom retiniranih nadoknada na implantatima
Dental cements have been established in practice since 1878, and technological advances in the field of implant pros-thetics have directly influenced the development of materials in this area. Although the retention type of implant-supported restorations can be dual, it is nowadays known that the overall rate of technical complications is higher for cement-retained restorations by 2% over screw-retained restorations. Biological complications, including peri-implant mucositis, periimplantitis, bone loss around implants, soft-tissue recession and fistula suppuration, are also more frequent with cement-retained restorations. The most common of these, periimplantitis is often related to factors depending on a clinician.Materijali za fiksiranje zubnih protetskih nadoknada utemeljeni su u stomatoloÅ”koj praksi od 1878. godine, a tehnoloÅ”ki napredak na polju implant-protetike direktno je uticao i na razvoj materijala u ovoj oblasti. Iako mehanizam vezivanja fiksnih nadoknada može biti dvojak, danas se zna da je ukupna stopa tehniÄkih komplikacija veÄa kod cementno retiniranih nadoknada za 2% u odnosnu na retenciju Å”rafom. BioloÅ”ke komplikacije u koje se ubrajaju periimplantatni mukozitis, periimplantitis, gubitak kosti oko implantata, recesija mekih tkiva i pojava fistule, takoÄe su uÄestalije kod cementno retiniranih zubnih nadoknada. Najzastupljenija meÄu njima, periimplantitis, Äesto se dovodi u vezu sa "lekar-zavisnim" parametrima
UÄinak razlike u procjeni osobne i supružnikove vrijednosti kao partnera na procjenu kvalitete braÄnog odnosa: dijadni pristup
The main aim of this study was to investigate the effects of
mate value assessment and mate value discrepancy on
perceived marital quality, using an assessment of personal
and partner mate value obtained by both partners. The
sample included 442 heterosexual couples that have lived
together for at least a year. The Actor-Partner
Interdependence Model (APIM) was used to investigate the
effects of personal and partner mate value assessment on
the evaluation of marital quality. In addition, two interaction
effects were added to the model to examine the effect of
mate value discrepancy on perceived marital quality. The
APIM model showed significant actor and partner effects of
the partner\u27s mate value assessment on the evaluation of
both husbands\u27 and wives\u27 marital quality. The model also
showed a significant effect of personal mate value assessed
by wives on husbands\u27 marital quality assessment. However,
the current evidence does not confirm the assumption of a
possible combination of partners\u27 mate value promoting
marital quality above and beyond the contribution of both
partners\u27 mate value.Glavni cilj ovog istraživanja bio je istražiti uÄinke procjene
osobne i supružnikove vrijednosti kao partnera i razlike u
spomenutim vrijednostima na procjenu kvalitete braÄnog
odnosa, koristeÄi se procjenom osobne i supružnikove
vrijednosti dobivene od oba partnera. Uzorak istraživanja
obuhvaÄao je 442 heteroseksualna para, koji su zajedno živjeli najmanje godinu dana. Model meÄuovisnosti aktora i
partnera (APIM) iskoriÅ”ten je za istraživanje uÄinaka procjene
osobne i supružnikove vrijednosti kao partnera na procjenu
kvalitete braka. Osim navedenoga, modelu su dodana dva
interakcijska uÄinka, kako bi se istražio uÄinak razlike u
procjeni osobne i supružnikove vrijednosti kao partnera na
procijenjenu kvalitetu braka. APIM model pokazao je
znaÄajne aktorske i partnerske uÄinke procjene supružnikove
vrijednosti kao partnera na procijenjenu kvalitetu braka
obaju supružnika. Model je pokazao i znatan uÄinak
procjene osobne vrijednosti supruge kao partnerice na
suprugovu procjenu kvalitete braÄnog odnosa. MeÄutim,
model ne potvrÄuje pretpostavku o interakcijskom uÄinku
procjene osobne i supružnikove vrijednosti kao partnera na
procjenu kvalitete braka
Uloga socijalne podrÅ”ke u relaciji izmeÄu razliÄitih strategija prevladavanja gubitka i emocionalnog distresa kod tugujuÄih starih osoba
Cilj ovog istraživanja je bio da se provere osnovne pretpostavke Dualnog proce- sa modela
prevladavanja gubitka, kao i da se utvrdi da li socijalna (emocional- na i instrumentalna)
podrÅ”ka moderira relaciju izmeÄu strategija prevladavanja iz ovog modela i emocionalnog
distresa tugujuÄih starih osoba. U istraživanju je uÄestvovalo 64 ispitanika, ujednaÄenih po polu,
kojima je u poslednjih 40 dana preminuo partner2. ProseÄna starost ispitanika bila je 71.9 godina
(SD=6.02) sa
rasponom od 65 do 89 godina. Za merenje moderatorskih varijabli koriÅ”Äene su jednoajtemske mere
emocionalne i instrumentalne podrÅ”ke, za merenje predik- torskih varijabli je koriÅ”Äen
Upitnik dnevnog udoviÄkog života (IDWL; Caserta &Lund, 2007), a za merenje kriterijumske varijable Skala depresivnosti, anksiozno- sti i stresa
(DASS-21, Lovibond & Lovibond, 1995). Rezultati najpre sugeriŔu da je usmerenost na gubitak u
pozitivnoj, a usmerenost na proradu u negativnoj vezi sa emocionalnim distresom. Osim toga,
emocionalna i instrumentalna podrŔka ostvaruju glavne efekte na emocionalni distres, ali i
moderiraju vezu izmeÄu stra- tegija prevladavanja i ovog ishoda adaptacije na gubitak. Stari koji
su visoko usme- reni na gubitak imaju ujednaÄeno visok nivo emocionalnog distresa, bez obzira na
nivo socijalne podrÅ”ke. MeÄutim, stari koji su niske usmerenosti na gubitak, a koji imaju viÅ”u
socijalnu podrŔku, imaju manji emocionalni distres od starih koji imaju nižu socijalnu podrŔku. Sa druge strane, stari koji su niske usmerenosti na proradu, a imaju viŔu emocionalnu
podrÅ”ku imaju manji emocionalni distres od onih sa nižom emocionalnom podrÅ”kom. Diskutovane su teorijske i praktiÄne

Therapeutic efficacy of connective tissue autotransplants with periosteum and platelet rich plasma in the management of gingival recession
Background/Aim. Gingival recession progression in clinical practaice has influenced the development of various surgical procedures and techniques for solving esthetic imperfections and subjective difficulties coused by gingival recession. The aim of this study was to verify efficacy of surgical procedures and to compare both of surgical procedures through the keratinized tissue width. Methods. The study included 20 teeth with gingival recesion, MĆ¼ller class I and II. Ten teeth with gingival recession were treated with connective tissue autotransplants with periosteum in combination with coronary guided surgical flap (CTG group). On the contralateral side 10 teeth with gingival recession were treated with the same surgical procedures but in combination with platelet-rich plasma (CTGPRP group). We measured the keratinized tissue width. For statistical significance we used the Student's t-test. Results. The study reveled a statistical significance in reducing vertical deepress of recession by both used treatments. Root deepness in CTG and CTG-PRP group was 90% and 93.5%, respectively. With both surgical techniques we achieved larger zone of keratinized gingiva but with a wide zone of keratinized tissue in CTG - the PRP group. Conclusion. The concept regeneration technique with PRP and with the stimulating influence of platele activated growth factors results in the regeneration of deep periodontal tissue as an important prerequisite for the successful treatment of gingival recession
PALLIATIVE CARE OF PATIENT WITH GASTROINTESTINAL CANCER IN FAMILY MEDICINE
Palijativna skrb je potpuna skrb za bolesnika Äiju bolest viÅ”e nije moguÄe aktivno lijeÄiti. Svrha palijativne skrbi je kontrola simptoma, produženje života uz postizanje najveÄe moguÄe kvalitete života za bolesnike i Älanove njihovih obitelji. U zavrÅ”nom razdoblju bolesti bolesnici 90 % vremena zadnje godine života provode u svom domu u skrbi obiteljskog lijeÄnika i njegovih suradnika te obitelji bolesnika. Bolesnici koji boluju od raka u posljednja tri mjeseca života imaju prosjeÄno 11,9 simptoma. NajÄeÅ”Äe su prisutni simptomi probavnog trakta te bol. Rast i Å”irenje raka kao i poduzeti terapijski postupci su najvažniji uzroci simptoma. NajÄeÅ”Äi simptomi u bolesnika s rakom probavnog sustava su muÄnina, povraÄanje, konstipacija, bol, kaheksija i anoreksija te psiholoÅ”ki problemi. Ovi najÄeÅ”Äi, ali i drugi simptomi bit Äe razliÄitog intenziteta i pojavnosti ovisno o sijelu i
agresivnosti raka probavnog sustava, oblika lijeÄenja te kondicije bolesnika. Bolesnici s uznapredovalim rakom preživljavaju sve dulje i svi zdravstveni profesionalci ukljuÄeni u skrb bolesnika trebaju imati sve viÅ”e znanja i vjeÅ”tina nužnih za uÄinkovito suzbijanje raznolikih simptoma. Koordinacija, organizacija i provoÄenje palijativne skrbi u obiteljskoj medicini kada se veliki dio skrbi pruža u domu bolesnika je jedan od najkompleksnijih zadataka lijeÄnika obiteljske medicine Taj zadatak zahtijeva od lijeÄnika obiteljske medicine specifi Äna znanja i vjeÅ”tine kako bi znao i mogao uÄinkovito pomoÄi u kontroli brojnih simptoma te pružiti primjerenu potporu bolesniku i njegovoj obitelji. Komunikacija izmeÄu lijeÄnika i bolesnika koji boluje od uznapredovalog raka probavnog sustava je temeljni aspekt skrbi. Kvaliteta komunikacije znaÄajno utjeÄe na tok lijeÄenja, dobrobit bolesnika i njegove obitelji, odluke o izboru lijeÄenja i suradljivost u lijeÄenju te na planiranje skrbi u buduÄnosti. U zbrinjavanju bolesnika s uznapredovalim rakom probavnog sustava lijeÄnik obiteljske medicine treba osigurati holistiÄki pristup te uvažavati bolesnika kao osobu i poÅ”tivati njegove odluke.Palliative care is defi ned as the care for patients whose disease is not responsive to curative treatment. The goals of palliative
care are symptom control, life prolongation and enabling the best possible quality of life for patients and their families. For most
patients with an advanced progressive incurable disease, 90% of care in their last year of life is provided at home by family physician
and his team and patient family. Patients suffering from cancer have a mean of of 11.9 symptoms in the last three months
of life. The most common symptoms are digestive tract symptoms and pain. The growth and spread of cancer, as well as the
therapeutic procedures applied are the most important causes of symptoms. The most common symptoms in patients with cancer
of digestive system are nausea, vomiting, constipation, pain, cachexia, anorexia, and psychological problems. These most
common symptoms and many others will be of varying intensity and appearance depending on localization and aggressiveness
of digestive system cancer, modality of treatment and patient condition. Patients with advanced cancer have longer survival
and all health care professionals involved in the care of patients should have more knowledge and skills necessary to effectively
treat various symptoms. Coordination, organization and implementation of palliative care in family medicine, when large part of
care is provided at patient home, are one of the most complex tasks of family physician. This task requires a family practitioner with specifi c knowledge and skills to know how effectively control a number of symptoms and to provide adequate support to the patient and his family. Communication between doctor and patient suffering from advanced cancer of digestive system is a fundamental aspect of care. The quality of communication signifi cantly affects the course of treatment, the benefi t to patients and their families, the choice of treatment and adherence to treatment, as well as care planning. In the management of patients with advanced cancer of the digestive system, family physician should use holistic approach and respect the patient as a person and his decision
Zadovoljstvo vezom kod homoseksualnih i heteroseksualnih parova: dijadski model
Rooted in Huston\u27s (2000) model of adjustment in romantic
relationships, the present study examined differences in
individual and relationship characteristics and the predictive
value of those characteristics for relationship satisfaction,
regarding four groups of participants, based on gender and
sexual orientation. The sample included a total of 100
heterosexual couples and 50 male and female homosexual
couples each. Of the individual characteristics, need for
affect achieves significant both actor and partner effects on
relationship satisfaction in all subsamples, except for
heterosexual women. A personal expression of love achieves
both actor and partner effects on relationship satisfaction for
heterosexual and homosexual men. The partner\u27s expression
of love (actor effect) on relationship satisfaction was
registered in all groups, except for homosexual men. The
present study offers the possibility of integrating knowledge
of the differences between heterosexual and homosexual
couples in the context of the model of adjustment in romantic
relationships.Ukorijenjena u Hustonovom (2000) modelu prilagodbe u
romantiÄnim vezama, svrha je ove studije bila provjeriti
postoje li razlike u individualnim znaÄajkama i znaÄajkama
veza izmeÄu Äetiriju skupina sudionika koje su formirane na
temelju spola i seksualne orijentacije te utvrditi prediktivnu
vrijednost jednih i drugih znaÄajki za zadovoljstvo vezom.
Uzorak je obuhvatio ukupno 100 heteroseksualnih parova i

Prevalencija Äetiri gena virulentnosti u sojevima Campylobacter jejuni izoliranima iz mesa brojlera u Srbiji
Campylobacter jejuni is a major cause of human diarrheal disease. The objective of this research study was to determine the prevalence of different virulence genes in isolates recovered from broiler meat at slaughterhouses in Serbia. Out of 115 Campylobacter spp. samples recovered, a total of 35 isolates were identified as C. jejuni on the basis of morphological, biochemical-based detection, multiplex PCR, and sequencing of the highly conserved region of the dnaJ gene encoding the DnaJ Hsp40 family protein. The isolates were screened for the presence of four pathogenic genes, namely flaA, cadF, cdtB, and cgtB, which are responsible for the expression of adherence, colonization, cytotoxin production in C. jejuni, and the onset of Guillain-Barre syndrome. The isolates showed a wide variation in the presence of these genes. All the isolates were positive for flaA. Furthermore, a high genetic heterogeneity in the C. jejuni population was found in this study, showing a pattern partially different from other reported virulence genes. Of the C. jejuni studied, 94.3%, 97.1% and 5.7% were positive for cadF, cdtB and cgtB, respectively. This study provides initial data on the prevalence and distribution of the flaA, cadF, cdtB, and cgtB genes in C. jejuni isolated from broiler meat in Serbia.Campylobacter jejuni vodeÄi je uzroÄnik crijevnih bolesti koje se oÄituju proljevom kod ljudi. Cilj ovoga istraživanja bio je utvrditi prevalenciju razliÄitih gena virulentnosti u izolatima dobivenima iz mesa brojlera u klaonicama u Srbiji. Na prisutnost vrsta roda Campylobacter spp. ukupno je pretraženo 115 uzoraka. MorfoloÅ”ko-biokemijskim pretragama, multipleks PCR tehnikom kao i sekvenciranjem visokooÄuvane regije gena dnaJ, koji kodira sintezu proteina DnaJ iz obitelji proteina Hsp40, 35 izolata identificirano je kao C. jejuni. Izolati su pretraženi na prisutnost Äetiri gena patogenosti: flaA, cadF, cdtB i cgtB. Ti su geni odgovorni za ekspresiju adherencije, kolonizacije, sinteze citotoksina C. jejuni kao i nastanak Guillain-Barreova sindroma. Izolati su pokazali Å”iroku varijaciju u prisutnosti tih gena. Svi su izolati bili pozitivni na gen flaA, pri Äemu je u populaciji C. jejuni iz ovoga istraživanja utvrÄena visoka heterogenost u genetskoj strukturi, koja je djelomice razliÄita od rezultata drugih autora. Kod 94,3 % izolata C. jejuni utvrÄen je gen cadF, kod 97,1 % gen cdtB, a kod 5,7 % gen cgtB. Ovo istraživanje pruža poÄetne podatke o prevalenciji i distribuciji gena flaA, cadF, cdtB i cgtB kod C. jejuni izoliranih iz mesa brojlera u klaonicama u Srbiji
Voice analysis before and after vocal tiredness
Background/Aim. A school teacher's occupation is one of the most vocal demanding professions. Vocal tiredness affects acoustic characteristics of voice, leads to the change in acoustic quality during vocal production. The aim of this study was to examine the influence of vocal tiredness on voice acoustic characteristics of school teachers. Methods. The study included 36 school teachers (16 male and 20 female) of 27-58 years of age. Vocal tiredness was evaluated by analyzing acoustic parameters of voice, using computerized laboratory "Kay Elemetrics". The voices were recorded before the first class on the beginning of a working week and after the last class at the end of a working week. Signal, noise and tremor parameters were processed. In their analysis the methods of descriptive statistics, as well as the analytical statistics (Student's t-test for paired samples, chi(2) test, Mann Whitney U-test and Pearson's correlation coefficient) were applied. Results. The obtained results showed statistically significant differences in average values of parameters as a consequence of the vocal tiredness (p lt 0.01), while gender, age and being smoker or not, did not have a significant effect on voice acoustic characteristics in this group of examinees (p > 0.05). Conclusion. The results of the study suggest a casual relationship between vocal tiredness and voice quality in vocal professionals
Wooden breast - a novel myopathy recognized in broiler chickens
Abnormally hard breast fillet consistency began to emerge in commercial broiler chickens around 2010. Due to the remarkable muscle hardness, the condition acquired the vernacular name wooden breast myopathy. This myopathy starts to develop after two weeks of age at the earliest and typically proceeds into chronic myodegeneration in three to four weeks of age. The lesion begins focally and typically develops into a diffuse lesion that involves the entire major pectoral muscle. The restricted location of wooden breast lesion in the m. pectoralis major distinguishes it from several other myodegenerative diseases that widely affect the skeletal muscle system and often the cardiac and smooth muscle systems too. Although industry-wide incidence rates are difficult to assess, it has been estimated that approximately 5-10% of commercially produced breast fillets exhibit severe WB. Even at low incidence rates, the costs to industry are substantial, as breast fillets with the wooden breast condition are often downgraded and sold at a discount, used for further processing, or in extreme cases, discarded. Because the etiology of wooden breast is still unclear, in the future, study of the early lesions, pathogenesis and the possible reduction of animal welfare are likely to gain more attention
