Sexual behaviour of Croatian blood donors as a threat to the health of blood recipients.

BACKGROUND In this cross-sectional study we assessed the prevalence of the various blood safety sexual risk behaviours among blood donors from East Croatia and the possibilities for improving the present blood donor screening procedure. MATERIALS AND METHODS The study included 423 blood donors of both sexes who completed a specially designed anonymous questionnaire immediately after their blood donations. The questionnaire contained questions on demographic data, sexual preferences, and possible sexual risk behaviours in the period before the blood donation. RESULTS The study revealed that the most common forms of sexual risk behaviour among Croatian blood donors had been irregular condom use during sexual contacts with new partners (294/423; 69.5%) and five or more sexual partners during the lifetime (213/423; 50.4%). More male than female subjects had had five or more sexual partners during their lifetime (p<0.0001). Compared to married donors, single subjects more frequently reported sexual contacts without using a condom with their new partners in the period from the last blood donation (p<0.0001) and also in the period of 1 month before current blood donation (p=0.0060). A larger number of younger than older subjects had practiced different types of sexual intercourses during the lifetime (p=0.0002) but more older than younger subjects reported irregular use of condom on sexual contacts with a new partner during their lifetime (p=0.0231). CONCLUSION Blood donors who were involved in various forms of sexual risk behaviour represent a serious threat to the health of blood recipients. In this respect a new approach to blood donor screening procedure with additional questions on sexual behaviour in anonymous donor questionnaires would improve the safety of transfusion treatment in East Croatia.

Attitudes toward Nutrition Care among General Practitioners in Croatia

Nutrition care should be an integral part of general practitioners’ (GPs’) daily work with patients. The aim of this study was to assess the attitudes of Croatian GPs toward nutrition and nutrition care, and to evaluate the interconnection between their attitudes and implementation of nutrition care in GPs offices. A cross-sectional study was conducted among 17.0% of randomly selected GPs, from May to July of 2013, via a specially designed anonymous questionnaire. The study showed that 36.0% of the Croatian GPs had satisfactory number of positive attitudes (5 or more) toward nutrition and nutrition care. There was statistically significant difference in the median number of positive attitudes based on the additional education of GPs in nutrition and their ailment from chronic diseases (p < 0.001 and p = 0.022, respectively). The Spearman rank correlation between GPs’ attitudes toward nutrition and nutrition care and their practice, i.e., the implementation of nutrition care in GPs’ everyday work with patients was rs = −0.235 (p < 0.001). In order to provide nutrition care in GPs’ offices in Croatia, strategies for changing GPs’ attitudes toward nutrition and nutrition care are needed.

Nutrition Counselling Practices among General Practitioners in Croatia

Chronic non-communicable diseases are a significant public health problem and imbalanced nutrition is one of the most significant risk factor for them. The objective of this study was to examine Croatia’s general practitioners’ nutrition counselling practice and determine the factors that influence such practice. A cross-sectional study was conducted among 444 (17.0%) randomly selected general practitioners (GPs) in Croatia from May to July 2013 via a 32-item anonymous questionnaire. Study showed that 77.0% of participants had provided nutrition counselling exclusively to patients with specific health risks; 18.7% participants had provided nutrition counselling for all patients, regardless of their individual risks, while 4.3% had not provide nutrition counselling. As the most significant stimulating factor for implementing nutrition counselling in their daily work with patients, 55.6% of the participants identified personal interest regarding nutrition and the effects it has on health. The latter factor was more frequently emphasized among female general practitioners (p < 0.001) and general practitioners without chronic diseases (p < 0.001). The most significant barrier for nutrition counselling was lack of time (81.6%). It is necessary to make additional efforts to increase the frequency of nutrition counselling provided by general practitioners in Croatia. The majority of Croatian general practitioners could increase their nutrition counselling practice in order to promote balanced nutrition and improve the overall health status of their patients.

The Nutrition Knowledge of Croatian General Practitioners

Nutrition care delivered in primary health care setting is an effective and necessary preventive health care measure. General practitioners (GPs) nutrition knowledge is related to their nutrition care practice. The aim of this study was to explore the nutrition knowledge of Croatian GPs, and to investigate its connection with the implementation of nutrition care in GPs’ offices. A cross-sectional study was conducted among 17.0% of randomly selected GPs, from May to July 2013, via an anonymous questionnaire. The study showed that only 35.8% of the Croatian GPs had an adequate level of nutrition knowledge (five or more correct answers to nutrition questions). The study further revealed that females, GPs with additional education in nutrition and GPs who had not suffered from chronic diseases with poor nutrition posing as a risk factor had better nutrition knowledge (p = 0.029, p < 0.001 and p = 0.041, respectively). The Spearman rank correlation between GPs’ nutrition knowledge and the implementation of nutrition care in their offices during daily work with patients was rs = −0.190 (p < 0.001). To provide nutrition care in GPs’ offices in Croatia, strategies for improving GPs’ nutrition knowledge are needed.

Alcohol-Related Injuries Among Eastern Croatian University Students

ABSTRACT The aim of this study was to describe the alcohol consumption patterns and to identify the association of injury with excess drinking among Croatian students. This cross-sectional study was conducted among 845 university students by the use of the WHO AUDIT questionnaire. A total of 39.9% of the university students reported some level of excess drinking and 21.3% reported that injury to themselves or others occurred as a result of their alcohol use. Conclusively, these results demonstrate a significant need for comprehensive programs to reduce alcohol intake and associated alcohol problems, as well as programs to reduce injuries among Croatian university students.

Psoriasis Severity—A Risk Factor of Insulin Resistance Independent of Metabolic Syndrome

Background: It is still debatable whether psoriasis increases cardiovascular risk indirectly since it is associated with metabolic syndrome or is an independent cardiovascular risk factor. The aim of this study was to evaluate psoriasis severity as an independent predictor of insulin resistance (IR) irrespective of the presence of metabolic syndrome (MetS). Methods: This was a case control study including 128 patients stratified into two groups: patients with psoriasis and metabolic syndrome vs. patients with psoriasis and no metabolic syndrome. MetS was diagnosed according to ATP III criteria with homeostatic model assessment of insulin resistance (HOMA-IR), as well as a homeostatic model assessment of beta cell function (HOMA-β) were calculated. Results: Compared to subjects without metabolic syndrome, patients with metabolic syndrome had a significantly higher Psoriasis Area Severity Index (PASI) values (p < 0.001). The strongest correlation was established for HOMA-IR and the PASI index (p < 0.001), even after adjustment for body mass index (BMI) in regression analysis model. In patients without MetS and severe forms of disease, the HOMA-IR and HOMA-β values were significantly higher compared to mild forms of disease (p < 0.001 for all) while in subjects with MetS no difference was established for HOMA-IR or HOMA-β based on disease severity. Conclusions: Psoriasis severity is an independent risk factor of HOMA-IR, the strongest association being present in the non-MetS group, who still had preserved beta cell function suggesting direct promotion of atherosclerosis via insulin resistance depending on the disease severity, but irrespective of the presence of metabolic syndrome.

Influence of Dietary Supplementation of Propolis and Bee Pollen on Liver Pathology in Broiler Chickens

Simple Summary Today, there are increased demands for consumers to use natural products as alternative additives in broiler feeding. In this study, we evaluated the effects of propolis and bee pollen as potential new additives on liver pathology in broilers. The results of this study showed that supplementation of broilers with propolis and/or bee pollen has a strong protective effect on liver pathology. Thus, these natural agents can be used as alternative additives in modern broiler production. Such an approach will enable the production of chicken meat enriched with bioactive substances from propolis and/or bee pollen, such as flavonoids, that have been proven beneficial for human health. Abstract One of the major problems in intensive breeding of chickens is liver damage. The objective of this study was to determine the influence of dietary supplementation with propolis and bee pollen on liver pathology in broiler chickens. The study was conducted on 200 Ross 308 chickens equally distributed by sex that were divided into five groups. Throughout the whole study, the control group of chickens was fed with a basal diet, while the experimental groups of chickens were fed with the same diet further supplemented with propolis and bee pollen, each supplement given separately or in combination in a certain proportion. The study showed that the clusters of lymphocytes in the hepatocytes, the vacuolar degeneration and necrosis of the liver parenchyma, the bile ductule hyperplasia, and the various forms of pathological changes in the liver arteries and veins were more frequent in liver tissue samples of the control group compared to liver tissue samples of all the experimental groups (p < 0.001). The study further showed that all the previously mentioned histopathological lesions of liver tissue were always more extensive in the liver tissue samples of the control group than in the liver tissue samples of all the experimental groups (p < 0.001). The supplementation of broiler chickens with propolis and/or bee pollen has a strong protective effect on liver pathology in broiler chickens.

The effects of propolis and bee pollen supplementation on biochemical blood parameters of broilers

Abstract The aim of this study was to determine the effect of propolis and bee pollen on selected biochemical blood parameters in broiler chickens. This experimental study was conducted on 200 Ross 308 chickens of equally distributed sex, which were divided into five groups (a control group and four experimental groups). Throughout the whole study the control group of chickens was fed the control feed mixture while the feed mixture that was fed to the experimental groups of chickens contained additives (propolis and/or bee pollen, each supplemented separately or in combination in a certain proportion). The results obtained by this study are: significantly lower blood glucose, cholesterol and calcium levels (P < 0.001), as well as significantly lower triglycerides levels (P = 0.002), but also significantly higher sodium and chloride (P < 0.001), phosphorus (P = 0.004) and globulins levels (P = 0.027) in chickens of the experimental groups compared to the chickens of the control group on the 21st day of fattening. Furthermore, this study has found significantly lower blood glucose (P = 0.033) levels and significantly higher levels of total proteins and globulins (P = 0.003), as well as albumins (P = 0.040) in chickens of the experimental groups compared to the chickens of the control group on the 42nd day of fattening. It can be concluded that the application of propolis and bee pollen as additives in broiler feeds enables the production of more vital and healthier animals, which significantly improves the fattening of chickens.

Transgenerational transmission of violence among parents of preschool children in Croatia

The aim of this study was to determine whether there is a transgenerational transmission of violence within the family on a sample of parents of preschool children in Croatia, and to identify the factors that increase the likelihood of child abuse. The Child Abuse Questionnaire was self-administered to the sample of 118 parents of preschool children (91 mothers and 27 fathers) during February 2013. There were 7.7% of mothers and 3.8% of fathers who answered that they slapped their child, while 15.4% of the fathers answered that they even hit their child with a fist. We found the subjects who were psychologically and/or physically abused in childhood by their parents to have a higher probability of following the exact model of violence on their children. So, children suffer physical violence in larger families from parents who, in turn, suffered physical violence in childhood from their fathers, controlled for all other factors in the model. Children suffer psychological violence from parents who experienced psychological violence from their own parents during childhood, controlled for all other factors in the model. We also found the higher number of family members in a household to be a risk factor for abuse. The study has confirmed that additional interventions are necessary to break the model of transmitting violence from generation to generation.

Is there connection between the exposure to various physical factors of the working environment and the occurrence of sick building syndrome

Background: The sick building syndrome (SBS) is environmentally related condition with increased prevalence of non-specific symptoms among the populations of certain buildings. Aim: To determine the frequency of exposure of the employees of public institutions from the city of Osijek to harmful physical factors of the working environment, to assess whether there is a connection between the exposure to these factors and the incidence of SBS symptoms and to clarify the nature of this connection. Methods: This cross-sectional study was conducted during May 2013 among 178 employees (33.7% males and 66.3% females ; average age 39.3±10.4 years) of public institutions in the city of Osijek (eastern Croatia). An anonymous questionnaire which contained questions relating to demographic data and working status of the participants, questions concerning their exposure to various harmful physical factors of the working environment and occurrence of certain symptoms of SBS among them was used as a research tool. Results: 80.9 % (144/178) of participants were exposed to harmful physical factors of the working environment. Employees exposed to those factors more frequently expressed symptoms of SBS. The incidence and the number of symptoms of SBS among employees simultaneously grew with the increase of the number of harmful physical factors of the working environment to which they were exposed. Conclusion: There is a need for continuous implementation of preventive activities in the workplace aimed at preventing and mitigating the impact of harmful physical factors of the working environment, which will help prevent SBS and also significantly improve health of employees.
