Biosecurity level and health management practices in 60 Swedish farrow-to-finish herds

Background: Biosecurity measures are important tools to maintain animal health in pig herds. Within the MINAPIG project, whose overall aim is to evaluate strategies to raise pigs with less antimicrobial use, biosecurity was evaluated in medium to large farrow-to-finish pig herds in Sweden. In 60 farrow-to-finish herds with more than 100 sows, the biosecurity level was evaluated using a previously developed protocol (BioCheck). In a detailed questionnaire, internal and external biosecurity was scored in six subcategories each. An overall score for biosecurity was also provided. Information regarding production parameters as well as gender and educational level of personnel working with the pigs was also collected. Descriptive statistics were used to examine the recorded data.Results: The median scores for external and internal biosecurity were 68 and 59, respectively, where 0 indicates total absence of biosecurity and 100 means maximal possible biosecurity. The subcategories for external and internal biosecurity that had the highest scores were "Purchase of animals" (external) and "Nursery unit"/"Fattening unit" (internal), while "Feed, water and equipment supplies" (external) and "Measures between compartments and equipment"/"Cleaning and disinfection" (internal) received the lowest scores. A female caretaker in the farrowing unit, a farmer with fewer years of experience and more educated personnel were positively associated with higher scores for some of the external and internal subcategories. In herds with < 190 sows, fattening pigs were mixed between batches significantly more often than in larger herds.Conclusions: The herds in this study had a high level of external biosecurity, as well as good internal biosecurity. Strong biosecurity related to the purchase of animals, protocols for visitors, the use of all-in, all-out systems, and sanitary period between batches. Still, there is room for improvement in preventing both the introduction of disease to herds (external) and the spread of infections within herds (internal). Systems for animal transport can be improved and with respect to internal biosecurity, there is especially room for improvement regarding hygiene measures in and between compartments, as well as the staff's working procedures between different groups of pigs

Assigning defined daily doses animal: a European multi-country experience for antimicrobial products authorized for usage in pigs

Objectives To establish a consensus defined daily dose animal (DDDA) for each active substance (AS) and administration route for porcine veterinary antimicrobial products authorized in four European countries, thus allowing cross-country quantification and comparison of antimicrobial usage data. Methods All veterinary antimicrobial products authorized for porcine use in Belgium, France, Germany and Sweden were listed for each administration route. First, separate DDDAs for each product were defined based on the recommended dosing for the main indication. Second, a consensus DDDA was established by taking the mean of the DDDAs for each product within a certain category of AS plus administration route. Results One-hundred-and-fifty-nine, 240, 281 and 50 antimicrobial products were licensed in Belgium, France, Germany and Sweden, respectively, in February 2013. Large variations were observed for dosage and treatment duration recommendations between products and between countries for the same ASs. Only 6.8% of feed/water and 29.4% of parenteral AS groups had the same recommended dosage in the four countries. Conclusions This study presents a consensus DDDA list for use in the quantification and comparison of antimicrobial consumption. Four major recommendations have been formulated: (i) urgent need for harmonization of authorization and recommended summary of product characteristics (SPC) dosages; (ii) expand the developed preliminary DDDA list to include all authorized veterinary medicinal products in all EU member states and for all (food-producing) animal species; (iii) improved accessibility of country-specific SPC data would be preferable; and (iv) statement of the ‘long-acting' duration of a product in the SP

Tillämpning av LFF i ljuset av LUFV : Har LUFV genom tillkomsten av LFF i någon mån blivit obsolet?

Uppsatsen tar upp de regler som styr den verksamhet, som försäkringsbolag från länder utanför EU bedriver i Sverige. Det handlar vidare om hur dessa regler påverkas av den lagstiftning som trädde i kraft 1 juli 2005, vilken styr försäkringsförmedlares verksamhet

Intra- and inter-rater reliability of the Sollerman hand function test in patients with chronic stroke

Purpose. To examine whether the Sollerman hand function test is reliable in a test-retest situation in patients with chronic stroke. Method. Three independent examiners observed each patient at three experimental sessions; two days in week I (short-term test-retest) and one day in week 4 (long-term test-retest). A total of 24 patients with chronic stroke (mean age; 59.7 years, mean time since stroke onset 29.6 months) participated. The examiners simultaneously assessed the patients' ability to perform 20 subtests. Both ordinal data (generalized kappa) and total sum scores (Spearman's rank correlation coefficient (Spearman's rho), intra class correlation coefficient (ICC2,1) and mean differences) were used in the statistical analysis. Results. There was agreement (kappa >= 0.4) between the examiners for 15 out of the 20 subtests. Using total sum scores, the agreement within the examiners, both short- and long-term, was higher than 0.96 (for Spearman's rho and ICC, respectively). The mean differences were 0.29-1.0/80 points within each examiner. Agreement between the examiners at each session was higher than 0.96 (Spearman's rho) and 0.92 (ICC), respectively. Systematic differences (p < 0.05) were, however, found between examiners A and B/C for all sessions. Conclusions. The Sollerman hand function test seems to be a reliable test in patients with chronic stroke, but we recommend that the same examiner evaluates a patient's hand function pre- and post-treatment

Pain when walking: individual sensory profiles in the foot soles of torture victims - a controlled study using quantitative sensory testing

Abstract Background With quantitative sensory testing (QST) we recently found no differences in sensory function of the foot soles between groups of torture victims with or without exposure to falanga (beatings under the feet). Compared to matched controls the torture victims had hyperalgesia to deep mechano-nociceptive stimuli and hypoesthesia to non-noxious cutaneous stimuli. The purpose of the present paper was to extend the group analysis into individual sensory profiles of victims’ feet to explore possible relations between external violence (torture), reported pain, sensory symptoms and QST data to help clarify the underlying mechanisms. Methods We employed interviews and assessments of the pain and sensory symptoms and QST by investigators blinded to whether the patients, 32 male torture victims from the Middle East, had (n=15), or had not (n=17) been exposed to falanga. Pain intensity, area and stimulus dependence were used to characterize the pain. QST included thresholds for touch, cold, warmth, cold-pain, heat-pain, deep pressure pain and wind-up to cutaneous noxious stimuli. An ethnically matched control group was available.The normality criterion, from our control group data, was set as the mean +/− 1.28SD, thus including 80% of all values.QST data were transformed into three categories in relation to our normality range; hypoesthesia, normoesthesia or hyperesthesia/hyperalgesia. Results Most patients, irrespective of having been exposed to falanga or not, reported severe pain when walking. This was often associated with hyperalgesia to deep mechanical pressure. Hypoesthesia to mechanical stimuli co-occurred with numbness, burning and with deep mechanical hyperalgesia more often than not, but otherwise, a hypoesthesia to cutaneous sensory modalities did not co-occur systematically to falanga, pain or sensory symptoms. Conclusion In torture victims, there seem to be overriding mechanisms, manifested by hyperalgesia to pressure pain, which is usually considered a sign of centralization. In addition there was cutaneous hypoesthesia, but since there was no obvious correlation to the localization of trauma, these findings may indicate centrally evoked disturbances in sensory transmission, that is, central inhibition. We interpret these findings as a sign of changes in central sensory processing as the unifying pathological mechanism of chronic pain in these persons.</p
