Effekter av befintliga och eventuella framtida läkemedelsbehandlingar på morbiditet och mortalitet hos patienter med hjärtsvikt.

Background:  Heart failure is a multidimensional phenomenon with high mortality. Heart failure is treated with angiotensin converting enzyme (ACE) - inhibitors or angiotensin receptor blockers (ARBs) that counteract neurohormonal stimuli that occur in heart failure, as well as providing vessel dilatation, which reduces symptoms and the need for hospitalization and increases survival. Despite this, only about 50% of heart failure patients survive 6 years after diagnosis with drug therapy, and as heart failure is increasing globally, due to improved care and treatment and increasing life expectancy of the population, there is a great need for new drugs such as LCZ696 that acts by dual inhibition of the renin - angiotensin - aldosterone system and neprilysin inhibition.Objective: The aim of this literature study was to evaluate the efficacy of current treatment and possible future treatments on mortality and morbidity in heart failure patients.Results: The examined articles show that treatment with ACE inhibitors in patients with symptomatic heart failure reduces the risk of total mortality by 16% over 3.5 years, reduces all-cause mortality or hospitalization due to heart failure with NNT (number needed to treat) = 10.4 over 3.5 years and increases median survival by 9.2 months over 12.1 years in patients with asymptomatic heart failure. Treatments with high-dose ACE inhibitors reduce mortality and hospitalization because of cardiovascular causes and hospitalizations from any cause by NNT = 30 over 3 years. Beta-blockers reduce sudden death and total mortality and cardiac death or non - fatal myocardial infarction with NNT = 38 and NNT = 23, respectively, over 12 months.

Ger tillägg av ARB till redan pågående behandling med ACE-hämmare hos hjärtsviktspatienter bättre hälso- och kostnadseffekt?

Heart failure is a condition where the heart is incapable of providing adequate blood supply to different organs in the body. The underlying causes of heart failure is some kind of disorder in the heart function, and require careful diagnostics. The basic symptoms that arise from heart failure is difficulty in breathing, that aggravate when lying down, and fatigue. The patients? symptoms and impaired quality of life can be in different stages depending on the severity of the heart failure.

Varför väljer elever att söka maskinprogrammet?

Abstract The main aim for this research is to come to an understanding for why young people choose to apply for the machine program when the time comes for the students to make their choice of upper secondary school program. The second aim for this research is to try and come to an understanding on how to make the machine program more interesting for future students to apply to.  The method of this research is quality method with the usage of interviews. With a total of six students in the first grade going on a school in the middle part of the country I tried to get answers to my questions. There are many things that affect students when they are facing what gymnasium program to choose and a very common answer by students in this study is that friends and work after school are some of the reasons for why students choose, for example, the machine program. The study also shows that parents has less influence of the students choice of gymnasium program and in fact, all students in this study made the choice to pick the machine program as their gymnasium program, but not always the machine program as their first choice. With the comparison of similar studies with my study the results are often in line with what other scientist have come up with.

Specialistssjuksköterskans erfarenheter av att främja hälsa för patienter med hjärtsvikt : En intervjustudie på vårdcentraler

Background:Chronic heart failure (CHF) is a complex clinical condition. The higher survival rate after heart attack and other heart diseases, plus aging population, has led to more CHF patients. Symptoms can have negative impact on exercise capacity, ability to perform activities of daily living and quality of life. Heart failure clinics have been established to help better quality of life. Helping to stabilize and maintain patients´ health can reduce the need of hospital admission.

The data is used together with theclassification results of the listening experiment to train different machine learning algorithms toclassify the songs in different genres.The results indicate that using only drum sounds for genre classifications works well, both forlisteners and for machine learning methods..

Vad skapar stress respektive trivsel hos avverkningslag? : en jämförelse mellan bolags- och entreprenörslag

As a student during my studies, I have been told about entrepreneurs who have red numbers in their financial statements, and there is a forest machine operator shortage in Sweden. The basic idea of this thesis was to examine the underlying factors that may have caused the problems described above. The aim of this thesis was to investigate the factors that create stress and job satisfaction as a forest machine operator. The study was performed as a comparison between forest companies own harvesting teams and entrepreneur teams to investigate if there are any differences in stress and job satisfaction between the two different types of team. The study was conducted in collaboration with SCA Skog. The material for this study was collected by doing interviews with SCA's harvesting teams. A total of 27 forest machine operators were interviewed, divided into a total of 10 separate harvesting teams. It was very similar between the different type of teams, which situations the operators experienced stress.

Ett sviktande hjärta : patientupplevelser av att leva med en kronisk hjärtsvikt

As the occurrence of obesity increases amongst young people, so increases the risk of more people suffering from heart failure as early as during middle age. The aim is to describe the life experiences of middle aged persons living with chronic heart failure. The literature study is based on twelve published, qualitative, and scientifically proved articles derived from MedLine and Cinahl using queries representing the subject, as well as from manual searching in ScienceDirect and LIBRIS. These articles have been analyzed from a life world perspective. Four main themes and four sub themes were identified from the articles' results.

Molekylärgenetisk analys av dilaterad cardiomyopati hos hund :

Canine dilated cardiomyopathy (DCM) is a disease with high morbidity and mortality and with a high prevalence in certain breeds. Predominatly large breeds are affected, such as Great danes, Newfoundlands, Deerhounds and Dobermanns. One exception is Cocker spaniels, where both American and English Cocker spaniels are affected in a quite high frequency. Cardiomyopathy is characterised as a disease that affects the myocardium and gives an impaired heart function. To diagnose DCM following criteria have to be observed: 1. Dilation of the left ventricle. 2. Reduced systolic heart function. 3. Increased sphericity of the left ventricle. To be certain of the diagnosis, alternative reasons for the symptoms such as lung- and heart diseases with other etiologies have to be excluded Two different types of DCM have been found upon histological examination.

Are changes in heart rate and/or arborisation of vaginal mucus useful parameters for detecting heat in heifers? :

The milk production per cow has increased considerably during the last 50 years and due to the breeding for higher milk production also brings decreased reproduction efficiency. In a Swedish study 1996 it was shown that on average only half of all estruses were detected. Every time a farmer fails to detect oestrus it costs the farmer about 1200 Swedish crones and the need of means of detecting oestrus is therofore large. With this study we wanted to investigate if heart rate respectively crystallisation of vaginal mucus (arborisation) could be useful means of detecting oestrus. We monitored two oestrus cycles in four heifers.

Radon i flerbostadshus : Kartläggning av fastighetsförvaltarnas egenkontroll avseende radon

Radon is a hazardous substance that cannot be perceived by our senses. It has long been known that exposure to high radon levels for a long period of time will ultimately cause lung cancer. The Swedish Radiation Safety Authority estimates that 500 people die annually due to this. Although most of them are smokers, even non-smokers suffer from lung cancer caused by radon. The statutory value for radon in homes today is 200 Bq/m³.

En analys av Joseph Conrads roman Heart of Darkness samt novell An outpost of progress

Denna studie är en analys av romanen Heart of Darkness (1902) och novellen An outpost ofprogress (1898) av Joseph Conrad (1857-1924) i syfte att undersöka berättelsernashuvudsakliga tematik ur en postkolonial infallsvinkel samt vad Conrads avsikt tycks ha varitmed porträtteringen av elfenbensagenten Kurtz. För att genomföra denna analys har jag gjorten närläsning av Heart of Darkness samt An outpost of progress och samtidigt tolkathändelseförloppen.Tolkningarna är delvis mina egna samt delvis baserat på tidigare forskning. Efter att hagenomfört dessa närläsningar är min slutsats att Conrads huvudsakliga avsikt var att skildaden mänskliga moralens förfall genom den ondskefulla girigheten. Det är denna girighet somhan definierar som det mörka i en människas hjärta. Genom framställningen av Kurtz visarhan exempel på detta samt hur farlig en skicklig retoriker kan vara..
