Blodtrycksfall, pulstryck och lindriga kognitiva symptom - En polytom logistisk regressionsanalys

People live longer. There is a growing need to increase the knowledge of aging and of the need among the elderly for medical care in the near future. As a step towards meeting this need, a survey among the elderly in Skåne is made by the division of Geriatric Medicine in Malmö University Hospital. This survey is called Gott åldrande i Skåne, GÅS. A frequent decease among the elderly is Mild Cognitive Impairment (MCI).

The effect of low light intensities and red light on heart rate, blood pressure, respiratory rate and activity in dairy cows

Today dairy farmers in Sweden are obligated to have lights turned on during night time in addition to the mandatory daylight inlet. This presents a cost for the production but many argue that it can be economically beneficial, especially in loose housing of dairy cows. In loose housing and even more so in herds with automatic milking, well functioning cow traffic during all hours of the day is crucial to optimise production. In order to keep the cow traffic flowing, lights may be an important management tool. It is also perceived among farmers with tied up stall that night light decreases the incidents of cows accidental stepping on their own or neighbours udders.

Magnesiumintagets betydelse för blodtryck och magnesiumkoncentrationen i stickprov av urin, träck och blodplasma hos häst

The purpose of this trial was to evaluate the possibility to use sampling of faeces, urine and plasma, and measurements of blood pressure as methods of discovering hypomagnesemia in horses, as well as the application handiness of these methods. The most commonly used method of checking the magnesium status of a horse is to analyze samples of serum or plasma. The trial was of a switch-back design, in which the horses were used as their own controls. The animal material was five Swedish warm blooded trotters between six to ten years old, and weighing between 485-620 kg. The trial consisted of three periods that were two months each.

Att mäta ankeltryck i primärvården : Distriktssköterskors och distriktsläkares uppfattningar om en undersökningsmetod och dess användning

Background: Peripheral arterial disease (PAD), as a consequence of atherosclerosis in the arteria of the limbs, affects one of ten Swedes older than 65. PAD can develop slowly and silently, and involves an increased risk for cardiac infarction and stroke. Measurement of the patient´s ankle blood pressure and calculation of the ankle-brachial index is an evidence-based method to discover PAD. Objective: To investigate how district nurses and general practitioners perceive this method of examination and experience possible obstacles to why it is not more commonly applied at primary health care centres. Method: Data collected by semi-structured interviews have been processed by qualitative content analysis with a manifest onset.

Barnens kunskaper : En empirisk studie av barnens kunskaper om hjärtat, blodet och blodomloppet

AbstractThis report aims, through interviews, observations and literature review to examine what some of the youngest children know about the heart, blood and bloodstream. The sample size was twenty children, half of them are at the age of three and the other half is at the age of six.The interviews showed that children at the age of six had better knowledge than children at the age of three, but one child knew that we have the blood corpuscle in the body. He was also the only one who mentioned the blood corpuscle of all children who participated in the research. Children at the age of three could not see the functional relationship between the blood and heart. One child who was six years told that the air we breathe goes directly in the heart from where the blood is circulating to the rest of the body, together with the food.Keywords: heart, blood, bloodstream, the body.

Prehospital vätskebehandling vid stort trauma ur en sjuksköterskas perspektiv : En systematisk litteraturstudie

The aim of this study was to determine which type of fluid to use in trauma care to improve patient survival. The method used was a systematic review, where a total of 18 studies were reviewed and 13 included in the results. The inclusion criteria used in this study were Randomized controlled trial, or studies relevant for the purpose, written in English and published during the last ten years. The studies were identified in the PubMed data base. The results showed that in trauma with hypovolaemia, colloid infusion has a better effect than infusion of crystalloid fluid on blood pressure and colloid infusion reduced the body's cascade systems in a beneficial way. Colloid infusion administered to head injury patients lowered their intracranial pressure more than crystalloid infusion.

Aim: To describe nursing measures for prevention of pressure ulcers among elderly people in ordinary and nursing homes. Method: A literature review by structured analyze of scientific articles. Result: The analyze resulted in six subjects for prevention of pressure ulcers. These subjects were; risk assesment, nutrition, repositioning, skin/hygiene, nurse knowledge and documentation.

Blood compatibility of biomaterials made of recombinant spider silk

Native spider silk is an attractive lightweight natural polymeric material with a unique combination of strength, extendibility and flexibility. Synthetic, recombinant spider silk is an attractive biomaterial with several possible fields of application. When a foreign material is introduced to blood, this can for example cause unwanted coagulation and complement activation. The aim of this study was to investigate if coatings of heparin or albumin could improve the blood compatibility of films of recombinant spider silk and to develop an initial method to do so. Hypothetically, objects like pacemakers, stents and dental implants could be covered with spider silk films of high blood compatibility to reduce potentially harmful foreign body reactions caused by the immune defense. Increased blood compatibility would likely lead to improvements for both the individual patients and the society thanks to reduced load on healthcare institutions. Our objective was to assess the blood compatibility of both functionalized and non-functionalized recombinant spider silk by evaluating coagulation and activation of the complement system of the immune defense. Coagulation was evaluated visually on glass slides and complement activation was analyzed by measuring the concentration of the complement system mediator C3a in blood samples that had been exposed to the different materials. This study introduces a non-toxic and easy performed method of improving the blood compatibility of recombinant spider silk films by adding a heparin coating. Heparin coated surfaces had statistically significantly higher blood compatibility than uncoated surfaces. The effects of albumin coating of films were less clear compared to the results of heparin coated films. Complement activation could not be evaluated because of high activation in all samples prior contact with the materials that were included in the study..

Förebyggande djuromvårdnad mot post-anestetisk myopati hos häst

Post-anaesthetic myopathy (PAM) is a serious occasional complication of general anaesthesia in horses. It causes not only pain and suffering to the horse, but also suffering (trauma) to the owner with increased veterinary costs. In the worst case PAM can be fatal. The anaesthetic nurse must know which parameters have to be taken into consideration in the prevention of PAM, to be able to prevent it, and use that knowledge for the animals safety. The aim of this literature review was to investigate and make a presentation of the factors and measurements associated with PAM, with focus on how to monitor these measurements to prevent it from happening, and the advice a Veterinary nurse can give to the horse owner regarding this condition. According to literature there a few factors that greatly increase the risk of PAM, these include- hypotension, periods less than 60 mmHg significantly increases the risk.

Medborgare, sträck ut din arm : Bloddonation och blodhandel i Folkets Dagblad 1985-1998

The purpose of this BA-study is to analyse articles about blood selling and blood donations in the Chinese daily newspaper People?s Daily between 1985 and 1998.With publications of popular scientific material, reports from rallies and portraits of blood donating ?heroes? etc., the People?s Daily, i.e. the Chinese Com­mu­nist Party, actively addresses the underlying cultural reluctance to give blood by different means. People?s Daily and the CCP resolutely aims to transform negative Confucian and other traditional notions of losing blood into represen­tations of courage, honour, duty, etc.

Blodets biopolitik : Heterosexuell hygien och män som har sex med män

Following the wake of the AIDS-catastrophe in the beginning of the eighties, homosexual men or 'men who have sex with men' (MSM) have been barred from donating blood throughout the planet. In this thesis I look into the different discourses at play in the context of creating the legal framework for blood donation in Sweden. Genealogically tracing the emergence of the category of MSM and mapping how the category is brought to use in contemporary negotiations on blood safety, I scrutinize how scientific truth is established within blood transfusion practice. I argue that the rationality of risk group exclusion is contingent on economical grounds, and that the foucauldian concept of biopolitics could productively be used to understand this rationality. In particular, the concept of the 'biopolitics of blood' can be employed in order to understand the reluctance from the involved actors to acknowledge the heteronormative consequences of the legal framework of contemporary blood donation..

Förekomsten av trycksår hos patienter som genomgår brachybehandling vid prostatacancer

Prostate cancer is the most common cancer in men. One type of treatment is internal radiation therapy, brachytherapy. This treatment requires the patient to lie completely motionless and in lithotomy position. The purpose of this study was to investigate the prevalence of pressure ulcers associated with brachytherapy in prostate cancer at the UniversityHospitalin Uppsala. Furthermore, the purpose was to identify the most common location of pressure ulcer and to examine whether there were any connection between risk factors and possible pressure ulcers.

Hyperglykemi hos kor med löpmagsdislokation :

The main interest of this study was to investigate whether there is hyperglycemia or hypoglycemia in cows suffering from abomasal displacement and to evaluate the effect of transport on blood glucose. Thirty-six cows with left- or right-sided abomasal displacement were included in the study together with 17 cows with other diseases for comparison. Fifteen cows with abomasal displacement and 7 cows with other diseases were sampled before transport. One third of the cows with abomasal displacement had hyperglycemia when the transport effects were corrected for. Separating this group in left- and right-sided abomasal displacement we found significantly higher blood glucose and insulin levels among cows with right-sided abomasal displacement. An explanation for this difference may be a strong stress response secondary to the right-sided dislocation.

Energianalys av tryckluftsystem : så kan Billerud Skärblacka AB spara energi på tryckluft

Compressed air is a low efficiency media, and is thus very expensive to produce. This thesis work began by mind mapping how to create savings on the compressed air system at Billerud Skärblacka AB. Certain issues have been chosen for further studies.In order to identify the consumption of compressed air at PM 8 and 9, several measurements were made. At PM 8 there were not found any pressure drop, only large pressure variations for short periods of time. The causes of these pressure variations were not established.
