Aggression between laboratory mice is a common problem and can result in welfare issues such as mice hurting or killing each other and also stress. Swedish laws and regulations clearly states that mice must be housed with a companion due to their natural social structure. Many studies have investigated the effect off enrichment, group size, cage size and other potential changes in in their environment on the occurrence of aggression. Even with these changes aggression can exist and therefore a new solution was tested in this paper. The proposed solution was to house an intact mouse with a castrated one and thus fulfill laws and regulations while still maintaining the physiology of one of the mice for the purpose of medical experiments.

AimThe aim of the present investigation was to study the side distribution (right, left) and possible gender differences in terms of anterior cruciate ligament (ACL) Injuries in different sports.MethodThis Register study comprises a total of 27856 subjects from the Swedish National Anterior Cruciate Ligament Register. Side- distribution and possible gender differences were analyzed. The different sports consisted of aerobics, alpine skiing, basket, cross-country skiing, dancing, enduro, floorball, gymnastics, handball, ice hockey/bandy, martial arts, outdoor activities, racket sports, snowboard, soccer, and volleyball. Due to Injuries that had occurred in the traffic and at work 5076 subjects were excluded. Statistical data have been analyzed with one way ANOVA and x2 test and the Tukey post hoc test has also been used.

To be able to move around without having to think about each movement is for most people amatter of course. Todays society contributes to a life at high speed where the sparetime is oftenspend doing somekind of sport, even extreme sports which earlier only a few people wheredoing. This leads to not only good health effects but also to more Injuries. One of the mostcommon Injuries is the knee injury.Capio Artro Clinic is a clinic specialized in sports medicine and particulary patients with Injuriesin knee, shoulder, foot, hip or elbow. They perform a great part of all the crucial ligamentsurgeries in Sweden and has therefor also a lot of patients in need for rehabilitation of the knee.During the rehabilitation the load of the injuried knee is increased in steps.

Introduction: In January 2005, a nationwide mandatory bicycle helmet law for children under the age of 15 was introduced in Sweden. In the current study, the effect of this law was evaluated by analyzing national trends in hospital admissions due to bicycle-related head Injuries during the period 1998-2011.Methods: An interrupted time-series design with segmented regression analysis was used to evaluate the intervention effect on head Injuries as a percentage of all Injuries (%HI) among cyclists in age- and sex-specific groups. Effect was measured as a change in level and/or slope of the trend at the time of legislation.Results: A total of 35261 cyclists (0-54 years) were hospitalized due to a bicycle injury during the study period. Linear regression analyses of the entire study period (not segmented) showed significant year-to-year decreases in the %HI of 1.3-1.7% in all age and sex-specific groups (p < .0001). Results from the segmented regression analysis showed that, at the time of legislation, a significant drop in level occurred among males under 15 years (-4.5% [95% CI: -7.7% to -1.3%], p = .01) and a significant change in slope occurred among females aged 30-54 years (-1.6% [95% CI: -2.9% to -0.2%], p = .025).Conclusions: The law seems to have had an effect on males in the target population (<15 years).

Background: Patients with cervical spinal cord Injuries are often dependent on a mechanical ventilator due to the damage on the innervation to breathing musculature. During rehabilitation they have to be trained to regain own breathing. This unweaning process may give respiratory complications, which are main causes to morbidity and death. These respiratory complications are traditionally treated in an intensive care unit (ICU), which means that the patients have to return back to these emergency units.Aim: To investigate number, length and causes of returns to intensive care units and the length of the weaning process. Further, to compare if a multidisciplinary approach to the weaning process may reduce ICU returns and to shorten the weaning process.

Purpose.The purpose of this essay was formulated as to examine the relationship between the development of deaths caused by unintentional injury and fast economic development in a country. The purpose is to create a picture of the development in the chosen countries.Background.Injuries and the deaths that sometimes follow are a problem for all communities, if nothing else just because of costs and the absence of incomes for the state. Countries ability to restrain these deaths should be of interest. Studies show that the number of deaths causedby unintentional Injuries correlates inversely with the GDP/c, we can therefore expect that better economic conditions leads to fewer deaths and vice versa. It has been shown that an economic crisis often leads to considerably higher death rates.

Background: The prevalence of sphincter rupture during childbirth has increased in Sweden from half percent to three percent from 1973 to 1993. Women who undergo planned home birth have sphincter Injuries to a smaller extent than women who undergo planned hospital births. Objective: The purpose of this study was to describe women?s experience of the last stages of delivery during planned home birth. Design: Inductive content analysis of 150 randomly selected delivery reports.

Injuries and sick-leave is a common feature for reinforcement workers today. This is mainlydue to the fact that reinforcement work is done in an exposed environment with many stressfactors and highly repetitive work. These operations are often carried out in unsuitableworking positions, these positions creates a major burden on the bones and joints and causesmicro- damages on muscles. With repetitive work these Injuries are not given time to healproperly and will gradually become worse.The body will not be able to handle the stress of working in a work environment such as thisand musculoskeletal disorders can be a result of this. The injury will make itself known aspain in the musculoskeletal system and causes reduced movability; the injured worker willtherefore not be able to perform the same work tasks as before.

Det har länge varit känt att patientens perioperativa position kan orsaka symtom som förmodas uppstå genom tryck och sträckningar. Positionen vid laparosko-piska operationer anses öka risken för symtom och därför är perioperativ om-vårdnad av betydelse. Syftet var därför att undersöka hur frekvent positions- relaterade symtom förekommer vid laparoskopiska ingrepp och vilken betydelse de har för patienten. Studien genomfördes som en deskriptiv tvärsnittstudie och datainsamlingen gjordes med hjälp av symtomskattning och semistrukturerade intervjuer. Totalt 60 respondenter i åldern 19 till 75 år deltog i studien som pågick under åtta månader.

No accidents or Injuries should occur because of our public health care. It should be a place with high security and good quality in order to avoid this type of accidents. This is a tough situation when the public health care organization should have as good quality as possible despite savings. It is difficult for middle managers to improve patient safety in the absence of money.The purpose of this study is to explain the work with patient safety that middle manager perform during saving times. The perspective we will look into is how they work with patient safety as an ongoing change.

Syftet med denna studie var att analysera anmälda arbetsolyckor inom sjöfarten utefter frekvens och konsekvens och således kunna dra slutsatser om vilka arbetsolyckor som är allvarligast. Studiens syfte var också att finna eventuella samband mellan dessa olyckor. Efter kontakt med Sjöfartens arbetsmiljönämnd beställdes statistik från Arbetsmiljöverket. Denna statistik bearbetades på olika vis, bland annat genom att stora avgränsningar gjordes gällande typ av befattning ombord. Efter att ha studerat hur förutsättningarna för anmälan av arbetsskada förändrats valdes relevanta år.

Introduction: Balance is a complicated term which includes a static, dynamic and functional part. These parts have, during a long period of time, been included into the existing training programs through several different balance exercises, which aim to prevent sports Injuries mostly focused on the knee and ankle. In floorball these Injuries are common and a sports injury prevention program is required.Purpose: The purpose is to explain the balance term and relate it to injury prevention training and the existing theories. A second purpose is to see whether five weeks of balance training increases the balance ability in female floorball players and thereby increase the test values in the two tests.Method: Twenty female floorball players participated in the study and were divided into a training group and a control group. They performed a Star excursion balance test (SEBT) and a Multiple single leg hop stabilization test (MSLHST) before and after a five week training period, containing exercises of balance.Results: The training group showed improvement after the training period, however only one significant result was found.

Bakgrund: Antalet barn och ungdomar som deltar i organiserade idrotts- och fritidsaktiviteter ökar. Det ses också en ökning av intensiv träning i yngre åldrar. Detta kan leda till att barn och ungdomar utsätter sig själva för ökad risk för akuta skador och överbelastningsskador. Syfte: Att applicera och anpassa Oslo Sports Trauma Research Center (OSTRC) svenska enkät till ett pojklag inom juniorishockey under en fyraveckorsperiod samt att genomföra en skaderegistrering mot de fysiska hälsoproblemen (akut skada, överbelastningsskada och sjukdom) och belysa dessa inom juniorishockey. Material och metod: Samtliga spelarna i ett pojklag (ålder 15-18) i ishockey fick under fyra veckors tid fylla i OSTRC enkät en gång i veckan.

This is a degree project performed at Halmstad University in Sweden on the subject carpet ofreinforcement. This project is developed in association with Celsa Steel Service in Halmstad.The purpose of this report is to investigate how much time that can be saved if carpet ofreinforcement is used instead of the traditional way to work with reinforcement and seewhat kind of parameters that is important between the choices. We are also going to seehow this product affects the situation for reinforcement workers from an ergonomic point ofview.Carpet of reinforcement is made by straight reinforcement?s bars that are welded togetherwith steel bands. These rolls are made at a factory with a machine that welds together thebars in determined centre distance, with desired dimensions after the constructionengineers? blueprints.

This project is a step towards automatic firefighting. The goal is to decrease the number of personal Injuries by replacing the human firefighter with robots or similar technical tools. Especially in very hostile environments due to risk of explosions or building collapse. A robot is easy to replace and can be maneuvered from a safe distance. The idea of the project comes from the company Drones Networking which aims for developing a totally autonomous firefighting system.
