Dog attacks on children are a widespread problem, which can occur when parents fail to realise a potentially dangerous interaction between a dog and a child. The aim of the study was to evaluate the ability of parents to identify dangerous situations from several everyday child-dog interactions and to determine whether the participants connected these situations to a particular breed of dog. Five sets of photographs depicting potentially dangerous interactions from everyday situations between children and three dogs (one of each breed) were presented via an online survey to parents of children no more than 6 years old. Data from 207 respondents were analysed using proc GLIMMIX in SAS program, version 9.3. The probability of risk assessment varied according to dog breed (p < 0.001) as well as to the depicted situation (p < 0.001). Results indicated that Labrador Retriever was considered the least likely of the three dogs to be involved in a dangerous dog-child interaction (with 49% predicting a dangerous interaction), followed by Parson Russell Terrier (63.2%) and American Pit Bull Terrier (65%). Participants considered one particular dog-child interaction named 'touching a bowl' a dangerous interaction at a high rate (77.9%) when compared with the other presented situations, which were assessed as dangerous at rates of 48.4% to 56.5%. The breed of dog seems to be an influential factor when assessing a potentially dangerous outcome from a dog-child interaction. Contrary to our hypothesis, interactions involving the small dog (Russell Terrier) were rated more critically, similarly to those of the Pit Bull Terrier. These results suggest that even popular family dog breeds, such as Labrador Retrievers, should be treated with more caution.

The study examines an analysis and evaluation of iodine content in raw cow's milk in three regions of the Czech Republic between the years 2008 and 2018. Bulk milk samples were collected at dairy farms situated in South Bohemia, Central Bohemia, and the Vysočina Region. Iodine in milk was determined on the basis of alkaline ashing, using the spectrophotometric method according to Sandell-Kolthoff. The highest mean iodine content was measured in 2009 (485.5 ± 408.2 μg/l) and the lowest in 2016 (169.2 ± 71.7 μg/l). Since 2010 there has been a gradual decline of iodine concentration, from 479.5 ± 304.9 μg/l in 2010 to 231.2 ± 63.5 μg/l in 2018. A similar decreasing tendency was recorded in all the monitored regions. The percentage of samples containing iodine above 500 μg/l was on the decrease (37% in 2009; 0% in 2016–2018) and less than 80 μg/l (8% in 2009; 0% in 2017–2018). The current state corresponds to the requirements for iodine content in milk for human consumption. The study emphasizes the importance of continuous iodine content checks in milk and the related adjustments of iodine supplementation to the feeding rations of dairy cows.

Práce obsahuje údaje o obsahu jódu v moči především studentů Jihočeské univerzity v Českých Budějovicích. Do pokusu bylo zařazeno celkem 42 studentů a 21 zaměstnanců. Empirická data byla získána v rámci řešení grantového projektu GAJU 011/2013/Z. Obsah jódu ve vzorcích byl stanoven laboratorně spektrofotometricky po alkalickém spalování vzorku podle Sandell-Kolthoffa. Cílem práce bylo posoudit zásobení studentů a zaměstnanců Zemědělské fakulty Jihočeské univerzity v Českých Budějovicích (JU v ČB) jódem na základě vyšetření jodurie. Průměrný obsah jódu v moči u všech osob (n=63) byl 230,40±169,90 µg.l-1. U mužů byl průměrný obsah jódu v moči 244,59±190,46 µg.l-1, u žen (n=42) 223,18±157,82 µg.l-1. Hodnota mediánu se pohybovala u mužů i žen okolo hodnoty 150 µg.l-1. U 89,4 % vyšetřených odpovídala jodurie dostačujícímu, popřípadě nadbytečnému příjmu jódu, u 10,60 % pak různému stupni jodopenie. V zájmu prevence nežádoucího dopadu nutričního nedostatku nebo nadbytku jódu je doporučena pravidelná kontrola jodurie i u studentů vysokých škol.
The aim includes data of the iodine content in urine, mainly students of the University of South Bohemia in the České Budějovice. The experiment included a total of 42 students and 21 employees. Empirical data were obtained within the grant project GAJU 011/2013/Z. The content of iodine in the samples was determined on the basis of alkaline combustion by a spectrophotometric method according to Sandell-Kolthoff. The aim of the study was to assess the supply of students and staff Faculty of Agriculture, University of South Bohemia in the České Budějovice (JU v ČB ) iodine on urinary iodine examination. The average content in the urine of all (n=63) was 230.40±169.90 µg.l-1. Average iodine content in urine was 244.59±190.46 µg.l-1 for men (n=21), 223.18±157.82 µg.l-1 for women (n=42). The median value for women and men was approximately 150 µg.l-1. For 89.4% of the examined urinary iodine corresponded to sufficient, or excessive iodine intake, 10.6% corresponded to varying degrees jodopenie. In order to prevent the undesired impact of nutrient scarcity or excess iodine is recommended regular monitoring of urinary iodine even university students.

OBJECTIVES: The objective of the study was to assess the metabolic risk of excessive dietary iodine intake in ewes and neonatal lambs. DESIGN: Pregnant Šumava ewes received an experimental diet containing 3.1 mg iodine per kg of dietary dry matter in Group A (control, n=13, 6 ewes and 7 lambs) and 5.1 mg iodine per kg of dietary dry matter in Group B (experimental, n=12, 6 ewes, 6 lambs) for eight months. Iodine was administered to ewes as calcium iodate. TSH in blood serum; TT3, TT4, fT3, and fT4 in blood plasma were examined in both groups of ewes and lambs to assess the risks of iodine intake above the permitted limit, as it applies to thyroid gland activity. RESULTS: Group B ewes showed a significant increase in TSH and TT4 only on day 1 after parturition. The highest values of TT4, TT3, and fT3 in lambs were recorded on day 1 after birth. The lowest values of fT3 and fT4 in lambs were measured on day 60 after birth with no differences observed between the groups. In lambs of Group B the lower concentration of TSH until day 3 after birth was followed by a significant increase from day 10 after birth. CONCLUSION: Our results indicate a risk of postnatal hypothyroidism among lambs from pregnant and lactating ewes having a high iodine intake.

OBJECTIVES: The aim of the study was to compare iodine utilization from different sources by sows and their progeny and the levels of T3 and T4 in their serum. DESIGN: Pregnant Czech Large White × Landrace sows were fed with an experimental KPK diet (a diet for lactating sows) 14 days before parturition until weaning (at a piglet age of 28 days). In group A (n=50, 10 sows, 40 piglets) the feed was supplemented with KI (0.6 mg of iodine per kg of feed). Iodine enriched alga Chlorella spp. (0.6 mg of iodine per kg of feed) was used as a supplement in group B (n=50, 10 sows, 40 piglets). In group C (n=50, 10 sows, 40 piglets) the sows were injected i.m. with IFAE at a dose of 100 mg of iodine per sow. Iodine, T3 and T4 were measured in each group for comparison of iodine utilization. RESULTS: The use of IFAE resulted in higher serum concentrations in sows compared to KI and alga. In contrast, iodine concentrations in milk and piglets were lower when IFAE were used. We found a wide variation in the concentrations of T3 and T4 in the serum of piglets in all groups. CONCLUSION: Our results indicate a good utilization of iodized oil by sows. However, its transfer into milk is lower compared to the other iodine sources.
