Specificities of hand trauma in agriculture

Background/Aim. Hand injuries in agriculture are characterized by massive destruction of all tissues, frequent amputations of finger, hand and often the whole extremity. These injuries are mutilant and can cause death. The aim of this paper was to show the specificities of hand injuries in agriculture in regard to hand injuries of other etiology. Methods. We analyzed patients that were treated in the Department for Plastic and Reconstructive Surgery, Clinical Center Vojvodina, during a five-year period (2003-2007) because of hand injuries. Results. In a five-year period there were 366 patients hospitalized because of hand injuries, out of whom 36 injuries were related to agricultural machinery use. In both groups the number of patients trended to increased, with male gender being dominant. Most of the patients were young or middle-aged men. In agricultural injuries most of the patients were in the group of 41-50-year old (30%), while in the other group, the patients were younger (21-30-year old). Hand injuries in agriculture resulted in finger amputation in 92%, while in the other group that number was much smaller (13%). Skin defect reconstruction in agricultural injuries required complex methods of skin grafting or skin flaps in more than 71%, while this was necessary in only 10% of other hand injuries. Conclusion. Hand injuries in agriculture are very mutilant and often result in conquassation and finger amputation. A possibility to preserve tissue damaged in this way is very limited, and skin closer usually requires complex methods

FUNKCIJA INTERNE REVIZIJE I USKLAĐENOSTI POSLOVANJA U DRUŠTVIMA ZA OSIGURANJE/REOSIGURANJE

U cilju unapređenja efikasnosti sistema upravljanja rizikom i sistema interne kontrole u društvima za osiguranje neophodno je uspostaviti tzv. model "tri linije odbrane". Prva linija odbrane jeste interna kontrola, koja se uspostavlja putem politika i pisanih procedura. Druga linija odbrane jesu funkcije koje su deo sistema upravljanja ili sistema internih kontrola, ali nikako nisu interne kontrole, dok treću liniju odbrane predstavlja interna revizija. Treća linija odbrane je ex post kontrola u odnosu na internu kontrolu i funkcije koje su deo sistema upravljanja. Nacionalni propisi iz oblasti osiguranja su u prethodnom periodu u velikoj meri usaglašeni sa pravnim tekovinama Evropske unije. Međutim, kada je u pitanju definisanje sistema upravljanja u društvima za osiguranje neophodno je izvršiti dodatna usklađivanja. Kao primer može se navesti Zakon o osiguranju Republike Hrvatske, koji jasno definiše četiri funkcije sistema upravljanja u društvima za osiguranje. To su: funkcija upravljanja rizicima, funkcija praćenja usklađenosti, funkcija interne revizije i aktuarska funkcija. Sistem upravljanja u društvima za osiguranje, prvi put je u Republici Srbiji detaljnije uređen Zakonom o osiguranju iz 2014. godine. Osim Zakona on je uređen Odlukom o sistemu upravljanja u društvima za osiguranje/reosiguranje, a kojom takođe nije definisana funkcija praćenja usklađenosti kao samostalna funkcija navedenog sistema. Pomenutim podzakonskim aktom ona je definisana u okviru funkcije sistema interne kontrole tj. kao njen sastavni deo, a što je prema mišljenju autora pogrešan pristup. U cilju boljeg razumevanja i unapređenja sistema upravljanja, a naročito funkcije praćenja usklađenosti, neophodno je u narednom periodu izmeniti nacionalne propise u oblasti osiguranja. Kako je Strategijom za implementaciju solventnosti II u Republici Srbiji iz 2016. godine, Narodna banka predvidela da će se u narednom periodu izvršiti dodatno usklađivanja propisa iz oblasti osiguranja sa propisima Evropske unije, autori nastoje u ovom radu da daju svoje preporuke za unapređenje nacionalnog zakonodavstva

The effects of immunocastration on male pig yield parameters and meat quality

The aim of this study was to evaluate the effects of immunocastration on pork meat and carcass quality, compared to meat from surgically castrated males and entire males. Ninety (Duroc x Pietrain) x (Landrace x Yorkshire) crossbred pigs were assigned to three experimental groups: surgically castrated males (barrows; castrated up to the seventh day of age), entire males (males), and vaccinated males (immunocastrates). Carcass and meat quality characteristics such as weight of hot and chilled carcass, meat yield, chilling loss and chemical parameters were examined. Surgically castrated pigs had significantly lower (p lt 0.01; p lt 0.05) weight before slaughter, than males and immunocastrates, and also lower (p lt 0.01) warm carcass weight than males. The average carcass meatiness of castrates was significantly lower (p lt 0.01) than the average meatiness of males and immunocastrates. Chilling loss of barrows was significantly lower (p lt 0.01) than chilling loss of males or immunocastrates. It was also found that the chilling loss of immunocastrates was significantly lower (p lt 0.05) than chilling loss of males. According to the results obtained, it can be concluded that immunocastration could be a good alternative to surgical castration considering meat and carcass quality characteristics

Koncentracija arsena i teških metala u tkivu puževa

The aim of this study was to determine arsenic and heavy metal concentrations (lead, mercury, copper, cadmium, zinc, iron and manganese) in snail tissues (foot and digestive gland) obtained from snail farms in Serbia (near urban areas). Snail samples were analysed using atomic absorption spectrophotometry. A total of 730 individual snail samples were included in this study. Snails were packed into plastic bags and transported to the laboratory at the Faculty of Veterinary Medicine, University of Belgrade. The levels of arsenic and mercury in the examined snail tissues were below the detection limit of the analytical method. Concentrations of heavy metals were higher in digestive gland tissues than in foot tissues.Cilj ovog ispitivanja bio je utvrđivanje koncentracije arsena i teških metala (olova, žive, bakra, kadmijuma, cinka, gvožđa i mangana) u tkivima puževa (stopalo i digestivni trakt) poreklom sa odabranih farmi u Srbiji (u blizini urbanih područja). Uzorci puževa su analizirani pomoć u atomskog apsorpcionog spektrofotometra. U ovu studiju uključeno je ukupno 730 pojedinačnih uzoraka puževa. Uzorci su upakovani u plastične kese, dopremljeni u laboratoriju Veterinarskog fakulteta, Univerziteta u Beogradu. Nivo arsena i žive u ispitivanim uzorcima puževa bio su ispod granice detekcije analitičke metode. Koncentracija teških metala bila je već a u digestivnom tkivu u poređenju sa koncentracijom teških metala u stopalu puževa

Element concentration and fatty acid composition of Serbian bee bread

The element concentration (Cu, Fe, Zn, Mn, Cr, Co, Ni, Se, K, Na, Ca and Mg), heavy metal concentration (Cd, Hg, Pb and As) and fatty acid composition of 12 Serbian bee bread samples from different geographical origins were examined. The element concentration was examined using ICP-MS, and total lipids for fatty acid determination were extracted from homogenized bee bread samples with hexane/isopropanol mixture by accelerated solvent extraction. Potassium was the major element, ranging between 5515 +/- 361.20 mg/kg and 7487 +/- 381.50 mg/kg. The highest As and Pb concentrations were found in bee breads from Lazarevac. This bee bread also contained the highest level of PUFA and SFA. Also, the n-6/n-3 ratio ranged between 0.86 +/- 0.28 and 1.40 +/- 0.05, indicating bee bread can be a good source of unsaturated fatty acids. Bee bread could be useful in monitoring environmental contamination by heavy metals (Cd, Hg, Pb and As), although complex studies of all bee products give sufficient information on this topic

Psychosocial characteristics and motivational factors in woman seeking cosmetic breast augmentation surgery

Background/Aim. There are various opinions regarding the factors motivating women to undergo breast augmentation. The aim of this study was to estimate motivation for augmentation mammaplasty (AM), self-esteem and body image perception in breast augmentation patients. Methods. This prospective study involved AM patients operated in the Clinical Center of Vojvodina during a 3-year period. A total of 45 patients responded to our package of questionnaires designed to assess motivation for surgery, self-esteem level and body image perception. Those patients were compared to the control group of women who did not want to change their breast size, and who were similar in their age, social status and education level. Our package of questionnaires included a general questionnaire, Photographic Figure Rating Scale (PFRS) and Rosenberg’s Self-Esteem Scale. Results. Differences in marital status, educational level, habitation and employment status were statistically insignificant, but there was a significantly lower body mass index (BMI) in the operated women. Considering motives for surgery, a few factors were distinguished: desire to feel more feminine (82.2%), confident (75.5%) and attractive (73.3%), to feel less shy with men (64.4%), to improve their sex life (46.5%), teasing history (42.2%) and easier to find a partner (11.1%) and job (2.2%). Both groups demonstrated a high self-esteem level, but in the AM group results were lower than in the control group. The mean current self-rating by the PFRS in the group AM was lower than in the control group (4.28 ± 1.3 vs 5.12 ± 1.23, respectively) and this coincided with lower BMI in the AM group. The women in the AM group had chosen significantly smaller body size as maximally attractive, and had chosen a narrower attractive body size range than the women in the control group. Conclusion. Preoperative evaluation of patients’ motives for surgery can help surgeons to exclude woman with unrealistic expectations and different psychological problems

Microbiological status of minced pork meat in vacuum and modified atmosphere packaging

The aim of this study was to evaluate the effectiveness of different packaging conditions (vacuum and modified atmosphere) on the microbiological status (total viable count, lactic acid bacteria and Enterobacteriaceae), total volatile basic nitrogen (TVB-N) and pH in minced pork meat. Pork mince was packaged in vacuum, modified atmosphere with 20% O2, 50% CO2 and 30% N2 (MAP 1) or modified atmosphere with 20% O2, 30% CO2 and 50% N2 (MAP 2), refrigerated at 3±1°C and examined on the days 0, 3, 6, 9 and 12 of storage. The average total viable counts and total Enterobacteriaceae counts in vacuum packaged mince were statistically significantly higher (p lt 0.01; p lt 0.05) than in modified atmosphere packaged mince with both combinations of gases, on different days of storage. The largest decrease of total viable count and Enterobacteriaceae count was noted in modified atmosphere packaged mince with the higher concentration (50%) of CO2

Inhibitory effect of thyme and some essential oil components on Salmonella Senftenberg and Salmonella Give

Salmonella is a pathogen of public concern causing health and economic problems worldwide. Salmonella Enteritidis and Salmonella Typhimurium are the serotypes most commonly recognized as causes of human salmonellosis, which is why research is mainly dedicated to prevention or inhibition of these frequently reported serotypes, while less attention is dedicated to the uncommon Salmonella serotypes. Outbreaks of salmonellosis caused by rarer subspecies of Salmonella are increasing, which is why their control is needed. Essential oils derived from plants have gained attention mainly due to their antibacterial properties and potential to be used as a replacement for synthetic additives in the food industry. To the best of our knowledge, there are no literature data about the effect of essential oils on Salmonella Give. Therefore, the aim of this study was to evaluate the effect of thyme and oregano essential oils and thymol, carvacrol, cinnamaldehyde and eugenol on Salmonella Senftenberg and Salmonella Give. Results showed that there were no differences between the susceptibility of the examined Salmonella serovars to these essential oils and active compounds. Oregano essential oil, thymol and carvacrol exhibited greater antibacterial activity, followed by cinnamaldehyde, while the Salmonella serovars examined were most resistant to the effect of eugenol

Effect of conjugated linoleic acids in pig nutrition on quality of meat

Relationships among conjugated linoleic acid (CLA) in pig nutrition and carcass quality parameters (hot carcass weight, carcass yield and meatiness) and meat quality parameters (initial and pH value after 24, 48 and 72 h, temperature, drip loss, sensory color and marbling) were determined in pigs (crossbreeds Yorkshire x Landrace). Commercial CLA preparation containing 60% CLA isomers was included in the diet. No significant differences in performance parameters were found between pigs fed with CLA and control group during 60 days period. CLA supplementation in feed significantly increased SFA and decreased MUFA and PUFA fraction in pig muscles
