Modern aspects of social development brings new concerns that contribute to obesity, as a direct result of the overall abundance. Almost that there is declarative consistent view that obesity, according to its frequency, a global epidemic of the new millennium and that is because of the effect on the overall health of the necessary complementary multidisciplinary approach, because its prevention can prevent and significantly reduce the mortality rate. Technological development, automation in the food production, reduced participation of manual labor and a sedentary lifestyle, obesity causes an increase not only in highly industrialized, but in the less developed countries. Obesity is a direct temptations of modern civilization and a major challenge for a community where food is plentiful. This fact increases the responsibility of each individual and placed before him the obligation to recognize the causes of obesity, so that, by changing their behavior, could reduce the burden involved with obesity.

Tests have shown that adipose tissue is very important in the production of chemical substances that have a major impact on atherosclerosis. The basic fat cells adiposity is very active in bio secretion hormones and other substances. Adiposities secrete chemical substances such as leptin, resistin, adiponectin, and others who participate in metabolic processes. One of the most important adipocytokine affecting the formation and the regression of atheromas plaque in the coronary blood vessels are adiponectin and resistin. So our aim was to determine the value of the concentration of adiponectin and resistin on patient with myocardial heart attack and determine their correlation with the control group of healthy subjects. In this study were included 68 subjects, 40 with myocardial heart attacks and 28 control groups of normal healthy. In the group with myocardial 78.6% of respondents were male and 21.4% female. Tests have shown that the concentration of adiponectin in the group with myocardial heart attack was significantly lower than the control group (4.94 to 6.74, p=0.043, p<0.05. In the same study group average value of resistin was significantly higher than in the control group (15.73 to 7.88, p=0.001, p<0.01) (Student's t-test, p = 0.581, p> 0.05). All this indicates that in patients with myocardial heart attack there is a decline in the concentration of adiponectin, which has cardio protective effect. The increase in resistin in myocardial heart attack in directly related to the appearance of athermanous plaques in the coronary blood vessels and has a bad prognostic significance.

Fear of falling (FOF) is a significant health problem that can be present in the elderly, both in those that had experienced falling and in those that hadn`t. The aim of the study was to establish correlation of FOF with the following characteristics of the participants: sex, age, education, marital status and the number of falls in the previous year. Performed from October to December 2014, the research included 100 participants from general population older than 65 and covered by health visiting service of Dom Zdravlja Nis. The questionnaire for assessment of FOF - Falls Efficacy Scale (FES) and the epidemiological questionnaire were used in all participants. We established that there is statistically significant difference of FES values (hi-kvadrat=7.668, p<0.05) between different age groups. It was found that median value of FES questionnaire is statistically significantly higher in participants living as singles in relation to those living in a community (U=828.0, p<0.05). There is satistically significant medium correlation between FES values and the number of falls in the previous year (r=0.661, p<0.01). This research established that FOF is associated with age and the number of falls in the previous year, that implies the need for prevention of FOF, especially in elder people and in people that experienced one or more falls. Implementation of prevention is also important in people living alone because FOF is excessive in their case.

Karcinom grlića materice je ozbiljan javno zdravstveni problem kako u svetu tako i kod nas. Kontrola karcinoma grlića materice pored prevencije podrazumeva ranu dijagnostiku i lečenje, ali i preciznu registraciju i praćenje obolelih žena. Da bi bila obezbeđena dobra kontrola bolesti, svi ovi delovi sistema moraju funkcionisati paralelno. Cilj rada je sagledavanje osnovnih deskriptivno-epidemioloških karakteristika obolelih i umrlih žena od raka grlića materice u svetu, Evropi i Srbiji. Poseban osvrt i detaljan epidemiološki prikaz usmeren je na područje centralne Srbije za period od 1999. do 2011. godine. U radu je primenjen deskriptivno-epidemiološki metod. Kao izvor podataka korišćeni su podaci Globocan-a (softver za procenu opterećenja bolesti populacije, pokrenut od strane WHO), kao i podaci Registra za rak centralne Srbije za analizirani period. U svetu, broj novoobolelih slučajeva za 2012. g. je 527624 (standardizovana stopa incidencije je 14,0 na 100000 žena). U pogledu mortaliteta, za dotičnu godinu broj umrlih žena je 265653 (standardizovana stopa mortaliteta je 6,8 na 100000 žena). Od karcinoma grlića materice na svaka 2 minuta u svetu umre jedna žena (720 dnevno). U Evropi, ukupan broj novoobolelih žena za 2012. g. je 58348 (11,44 na 100000 žena). Ukupan broj umrlih žena je 24378 (3,75 na 100000 žena). U Srbiji, ukupan broj novoobolelih žena za 2012. g. je 1501 (23,8 na 100000 žena). Ukupan broj umrlih žena je 609 (7,7 na 100000 žena). Pozicija Srbije u Svetu u pogledu obolevanja je 62 (od 182. zemlje), dok je 84. u pogledu mortaliteta, što nas svrstava u gornju polovinu liste svih zemalja u svetu. Prema podacima Registara za rak za centralnu Srbiju, prosečna standardizovana stopa incidencije od 23,9/100000 žena i mortaliteta od 7,2/100000 za period 1999-2011. godine ukazuju na nepovoljnu epidemiološku situaciju ovog malignoma u centralnoj Srbiji. Mada se analizom pomenutog vremenskog intervala registruje blagi pad trenda obolevanja u centralnoj Srbiji (y=27,13-0,47x; p>0,05, otprilike jedan slučaj karcinoma grlića materice na 100000 žena manje za sledeće dve godine). Naprotiv, za isti analizirani period, beleži se porast umiranja (y=7,16+0,01x; p>0,05).

Introduction: The study of importance of left ventricular contractile reserve presence and changes plasma brain natriuretic peptide levels (BNP) during exercise in patinets with idiopathic dilated cardiomyopathy is very popular today, but these two parametres have rarely been interconnected. The study of response BNP during echocardiography stress tests in patients with idiopathic dilated cardiomyopathy with or without preserved left ventricular contractile reserve. We studied 55 consecutive patients with idiopathic dilated cardiomyopathy (mean age 54.98 ± 9.84, 49 (89.1%) male) treated in the outpatient clinic for heart failure at the Institute of Cardiovascular Diseases "Dedinje". All the patients underwent the echocardiography stress test. Contractile reserve was assessed by measuring of the changes of the left ventricle ejection fraction basally and in the first minute after the strongest stress. Level of BPN was measured at rest, in the first minute and after 20 minutes of maximal exercise stress. Following the kinetics of BNP level during stress testing, we find that in patients with preserved left ventricular contractile reserve BNP level is rising at maximum load achieved (Mediana (IQR) - 59 (22-113) vs. 91 (37-135) vs. 78 (30-159) ng/L, p<0.001), whereas in patients without preserved left ventricular contractile reserve BNP level does not change significantly (Mediana (IQR) – 89 (50-322) vs. 119.5 (61.3-321.8) vs. 136 (72- 281), p=0.102). The increase in BNP in the peak load compared to its value at rest was positively correlated with preserved contractile reserve (r=0.38, p=0.009), better WMSI at rest (r=-0.28, p=0.04), greater difference in the double product (r=0.40, p=0.002), as well as the work accomplished on the test (r = 0.47, p <0.001), and longer duration of the test (r = 0.43, p = 0.001). The increase in BNP during physical exercise in patients with idiopathic dilated cardiomyopathy suggests a preserved contractile reserve of the left ventricle.

The mos Tooth whitening is a procedure that removes stains and various discolorations of tooth surface. Discoloration of teeth may be endogenous and exogenous nature. The aim of this study was to investigate the impact of bleaching combined with daily use of drinks that cause tooth discoloration. Evaluated the changes in surface structure of enamel, and changes in hardness after bleaching. Were 20 extracted teeth. The teeth are marked with longitudinal lines halves (medial vestibular and distal surfaces). Tretitana mesial half of the 16% carbamide peroxide, a distal was left as control. NDT device HL400DL, duroskopskom method of enamel hardness was measured before treatment, after treatment and after remineralization. Olympus inverted microscope GX41 enamel structures were observed in the treated and control half of the tooth. After bleaching there is a difference compared to the untreated surface, that surface is bleached a few shades lighter, but after the use of coffee and soft drinks teeth back to the original dark color. Enamel microhardness after the treatment is somewhat small but not significant. With a magnification of 2000x and see the structural changes in enamel. Tooth whitening, but that the remineralization and the abstinence from prebojenih beverages and tobacco.

Prognoza i izbor terapije adenokarcinoma prostate (ADKP) direktno zavise od brojnih prediktivnih faktora, među kojima su najznačajniji zbirni histološki gradus tumora (Gleason score, koji predstavlja zbir prvog i drugog dominantnog histološkog gradusa) i klinički stadijum. Novija istraživanja u ove faktore ubrajaju i tkivni androgen status i neuroendokrinu diferencijaciju. Važnost prvog i drugog dominantnog histološkog gradusa naročito postaje značajan kod ADKP Gleason score-a 7. Smatra se da goru prognozu imaju ADKP višeg Gleason score-a, uznapredovalog kliničkog stadijuma, androgen nezavisni tumori i tumori koji pokazuju veći stepen neuroendokrine diferencijacije. Cilj rada je odrediti prediktivni značaj ADKP Gleason score-a 7 (3+4) i ADKP Gleason score-a 7 (4+3) u odnosu na klinički stadijum, tkivni androgen status i stepen fokalne neuroendokrine diferencijacije. Istraživanje je obuhvatilo 33 ADKP Gleason score-a 7, odnosno 26 (78,79%) ADKP 7 (3+4) i 7 (21,21%) ADKP 7 (4+3). Svi tumori su najčešće dijagnostikovani u stadijumu D2 kada su već postojale udaljene metastaze. ADKP Gleason score-a 7 (4+3) dijagnostikovani su u većem procentu u ovom stadijumu, među njima ima više androgen nezavisnih tumora i pokazuju veći stepen fokalne neuroendokrine diferencijacije. Svi dobijeni rezultati u saglasnosti su sa podacima iz literature i navode na zaključak da ADKP Gleason score-a 7 (4+3) imaju goru prognozu od ADKP Gleason score-a 7 (3+4).

Dijagram toka studije predstavlja sastavni deo usklađenih standarda o izveštavanju (CONSORT). Preporučuje se njegova primena u izveštavanju ogleda sa klaster randomizacijom. Cilj rada je da se predstavi učestalost korišćenja dijagrama toka u klaster randomizovanim studijama u skladu sa standardima o izveštavanju. Urađeno je pretraživanje Medline-a i za analizu izdvojeno 474 studija sa klaster randomizacijom. Studije su pregledane u cilju otkrivanja upotrebe grafičkog prikaza, primene standarda o izveštavanju i vremena publikovanja studije. U zavisnosti od trajanja, studije su podeljene na one koje su prikazale završena istraživanja i one čije je izvođenje još uvek u toku. Učestalost dijagrama toka je bila statistički značajno veća u studijama koje su se pridržavale standarda (86,2%) u odnosu na studije koje nisu koristile CONSORT smernice (71,4%), i u studijama koje su prikazale završena istraživanja (81,2 %) u odnosu na studije koje su predstavljale pilot projekte (54,3%). Primena CONSORT-a je zabeležena u 145 (31%) literaturnih jedinica. Broj klaster randomizovanih studija dobijenih pretraživanjem MEDLINE-a niskom cluster randomized trial [ti] i cluster randomised trial [ti] i primena CONSORT-a u izveštajima klaster randomizovanih studija linearno rastu tokom vremena (p<0,001). Učestalost primene dijagrama toka je veća u izveštajima klaster randomizovanih studija koji su rađeni u skladu sa standardima o izveštavanju.

Tokom retrospektivne studije, koja je urđena u periodu od 01.01. do 31.12.2012.godine, pregledano je 1035 uzoraka vaginalnog sekreta, cervikalnog brisa i brisa uretre na UU i Mh. Osnovni cilj studije je bio utvrđivanje učestalosti infekcije Mikoplazmama, distribucije prema polu, godinama života pacijenata, kliničke dijagnoze zbog koje je urađeno mikrobiološko ispitivanje pacijenata i utvrđivanje osetljivosti izolovanih uzročnika na antibiotike. Od ukupno 1035 ispitanih uzoraka pozitivan nalaz je bio kod 331 pacijenta, od toga je 316 (95,5%) ženskog i 15 (4,5%) muškog pola. Razlika je statistički značajna. Nisu nađene statistički značajne razlike u prosečnoj starosnoj dobi između žena (29 godina) i muškaraca (30 godina). Infekcija samo sa UU je statistički značajno češća (70.1%) u odnosu na Mh (5.4%) i mešovitu infekciju (24.5%). Učestalost infekcije uzrokovane UU kod ženskog pola iznosila je 70%, a kod muškog pola 80%. Osobe muškog i ženskog pola ne razlikuju se statistički značajno prema učestalosti infekcije uzrokovane UU. Najveća učestalost pacijenata ženskog pola, bila je sa dijagnozom Vulvovaginitisa 34%, Colpitis je imalo 22%; Colpitis i Cervicitis-17%, dok je samo Cervicitis bio dijagnostikovan kod 10% bolesnica. Razlika u učestalosti kliničkih dijagnoza je statistički značajna. Svi izolovani uzročnici pokazuju statistički značajno veću osteljivost na tri i više antibiotika. Osetljivost na tri i više antibiotika nije statistički značajno povezana sa uzročnikom infekcije.
