Willy Brandts nya östpolitik 1969-1973. En teorikonsumerande studie av tysk utrikespolitik

In this thesis I will examine Willy Brandt's new Ostpolitik with the help of Robert Putnam's analytical framework of two-level games perspective and the theory of social constructivism. Firstly, I will briefly set out the development of Germany's history before it was divided into the Federal Republic of Germany and German Democratic Republic in 1949. After that I present West Germany's foreign policy from 1949 to 1969 in order to show how Willy Brandt continued and broke with different foreign policy doctrines. Finally, I want to illustrate his new Ostpolitik and the international and domestic factors, which contributed to its realisation. The main question of this essay is: How significant were the changes of the West German society for the realisation of the new Ostpolitik from 1969 to 1973? One of the most important findings in this essay is that on the one hand that many West Germans had accepted that their country was divided and on the other hand that many groups in the society such as the significant newspaper Die Zeit and intellectuals supported the new Ostpolitik. I come to these conclusions by using the theory consuming method

Weimarrepubliken 1918-1933 En metodologisk individualistisk studie om demokratins kollaps

The purpose of this essay was to analyze the collapse of democracy in the Weimar Republic. This was done by analyzing some of the most turbulent crises in its history like the communists attempt to take power in 1919, the kapp-putsch of 1920, hyperinflation 1923 and the economic depression 1929-1933. The method that I used in this essay is called methodological individualism. It was an analytical framework which helped to understand the citizens view on democracy and legitimacy. The theoretical framework was based on Juan J.Linz and Seymour Martin Lipsets ideas on legitimacy and efficacy. I also used Max Weber's theories on the charismatic leader and legitimacy. My conclusion is that the reason why democracy in the Weimar Republic collapsed was because different sectors of society stopped supporting it. Many conservative did not support democracy after the conference of Versailles 1919. Other groups like the middle class and the working class stopped supporting it during the great depression of 1929-1933. This led to the fact that the majority of citizens was not willing to defend democracy when Adolf Hitler became chancellor in 30th of January 1933 which contributed to the collapse of the Weimar Republic

Risk of primary lung cancer after adjuvant radiotherapy in breast cancer-a large population-based study

Adjuvant radiotherapy (RT) for breast cancer (BC) has been associated with an increased risk of later radiation-induced lung cancer (LC). We examined the risk of primary LC in a population-based cohort of 52300 women treated for BC during 1992 to 2012, and 253796 age-matched women without BC. Cumulative incidence of LC was calculated by the Kaplan-Meier method, and the risk of LC after BC treatment was estimated by Cox proportional hazards regression analyses. Women with BC receiving RT had a higher cumulative incidence of LC compared to women with BC not receiving RT and women without BC. This became apparent 5 years after RT and increased with longer follow-up. Women with BC receiving RT had a Hazard ratio of 1.59 (95% confidence interval 1.37-1.84) for LC compared to women without BC. RT techniques that lower the incidental lung doses, e.g breathing adaption techniques, may lower this risk.Peer reviewe

Risk of ischemic heart disease after radiotherapy for ductal carcinoma in situ

The use of adjuvant radiotherapy (RT) in the management of ductal carcinoma in situ (DCIS) is increasing. Left-sided breast irradiation may involve exposure of the heart to ionising radiation, increasing the risk of ischemic heart disease (IHD). We examined the incidence of IHD in a population-based cohort of women with DCIS. The Breast Cancer DataBase Sweden (BCBase) cohort includes women registered with invasive and in situ breast cancers 1992-2012 and age-matched women without a history of breast cancer. In this analysis, 6270 women with DCIS and a comparison cohort of 31,257 women were included. Through linkage with population-based registers, data on comorbidity, socioeconomic status and incidence of IHD was obtained. Hazard ratios (HR) for IHD with 95% confidence intervals (CI) were analysed. Median follow-up time was 8.8 years. The risk of IHD was not increased for women with DCIS versus women in the comparison cohort (HR 0.93; 95% CI 0.82-1.06), after treatment with radiotherapy versus surgery alone (HR 0.77; 95% CI 0.60-0.98) or when analysing RT by laterality (HR 0.85; 95% CI 0.53-1.37 for left-sided versus right-sided RT). The risk of IHD was lower for women with DCIS allocated to RT compared to non-irradiated women and to the comparison cohort, probably due to patient selection. Comparison of RT by laterality did not show any over-risk for irradiation of the left breast.Peer reviewe

The relationship between radiation doses to coronary arteries and location of coronary stenosis requiring intervention in breast cancer survivors

Abstract Background To assess the relationship between radiation doses to the coronary arteries (CAs) and location of a coronary stenosis that required intervention after three-dimensional conformal radiotherapy (3DCRT) for breast cancer (BC). Methods The study population consisted of 182 women treated for BC in Sweden between 1992 and 2012. All women received 3DCRT and subsequently underwent coronary angiography due to a suspected coronary event. CA segments were delineated in the patient’s original planning-CT and radiation doses were recalculated based on the dose distribution of the original radiotherapy (RT) plan. The location of the CA stenosis that required intervention was identified from the Swedish Coronary Angiography and Angioplasty Registry (SCAAR). Logistic regression analysis was used to assess the relationship between CA radiation doses and risk of a later coronary intervention at this specific location. Results The odds ratio (OR) varied by radiation dose to the mid left anterior descending artery (LAD) (p = 0.005). Women receiving mean doses of 1–5 Gray (Gy) to the mid LAD had an adjusted OR of 0.90 (95% CI 0.47–1.74) for a later coronary intervention compared to women receiving mean doses of 0–1 Gy to the mid LAD. In women receiving mean doses of 5–20 Gy to the mid LAD, an adjusted OR of 1.24 (95% CI 0.52–2.95) was observed, which increased to an OR of 5.23 (95% CI 2.01–13.6) for mean doses over 20 Gy, when compared to women receiving mean doses of 0–1 Gy to the mid LAD. Conclusions In women receiving conventional 3DCRT for BC between 1992 and 2012, radiation doses to the LAD remained high and were associated with an increased requirement of coronary intervention in mid LAD. The results support that the LAD radiation dose should be considered in RT treatment planning and that the dose should be kept as low as possible. Minimising the dose to LAD is expected to diminish the risk of later radiation-induced stenosis

An MR-based brain template and atlas for optical projection tomography and light sheet fluorescence microscopy in neuroscience

IntroductionOptical Projection Tomography (OPT) and light sheet fluorescence microscopy (LSFM) are high resolution optical imaging techniques, ideally suited for ex vivo 3D whole mouse brain imaging. Although they exhibit high specificity for their targets, the anatomical detail provided by tissue autofluorescence remains limited.MethodsT1-weighted images were acquired from 19 BABB or DBE cleared brains to create an MR template using serial longitudinal registration. Afterwards, fluorescent OPT and LSFM images were coregistered/normalized to the MR template to create fusion images.ResultsVolumetric calculations revealed a significant difference between BABB and DBE cleared brains, leading to develop two optimized templates, with associated tissue priors and brain atlas, for BABB (OCUM) and DBE (iOCUM). By creating fusion images, we identified virus infected brain regions, mapped dopamine transporter and translocator protein expression, and traced innervation from the eye along the optic tract to the thalamus and superior colliculus using cholera toxin B. Fusion images allowed for precise anatomical identification of fluorescent signal in the detailed anatomical context provided by MR.DiscussionThe possibility to anatomically map fluorescent signals on magnetic resonance (MR) images, widely used in clinical and preclinical neuroscience, would greatly benefit applications of optical imaging of mouse brain. These specific MR templates for cleared brains enable a broad range of neuroscientific applications integrating 3D optical brain imaging

Adjuvant Capecitabine for Early Breast Cancer: 15-Year Overall Survival Results From a Randomized Trial

PURPOSEFew data are available regarding the influence of adjuvant capecitabine on long-term survival of patients with early breast cancer.METHODSThe Finland Capecitabine Trial (FinXX) is a randomized, open-label, multicenter trial that evaluates integration of capecitabine to an adjuvant chemotherapy regimen containing a taxane and an anthracycline for the treatment of early breast cancer. Between January 27, 2004, and May 29, 2007, 1,500 patients with axillary node-positive or high-risk node-negative early breast cancer were accrued. The patients were randomly allocated to either TX-CEX, consisting of three cycles of docetaxel (T) plus capecitabine (X) followed by three cycles of cyclophosphamide, epirubicin, and capecitabine (CEX, 753 patients), or to T-CEF, consisting of three cycles of docetaxel followed by three cycles of cyclophosphamide, epirubicin, and fluorouracil (CEF, 747 patients). We performed a protocol-scheduled analysis of overall survival on the basis of approximately 15-year follow-up of the patients.RESULTSThe data collection was locked on December 31, 2020. By this date, the median follow-up time of the patients alive was 15.3 years (interquartile range, 14.5-16.1 years) in the TX-CEX group and 15.4 years (interquartile range, 14.8-16.0 years) in the T-CEF group. Patients assigned to TX-CEX survived longer than those assigned to T-CEF (hazard ratio 0.81; 95% CI, 0.66 to 0.99; P = .037). The 15-year survival rate was 77.6% in the TX-CEX group and 73.3% in the T-CEF group. In exploratory subgroup analyses, patients with estrogen receptor–negative cancer and those with triple-negative cancer treated with TX-CEX tended to live longer than those treated with T-CEF.CONCLUSIONAddition of capecitabine to a chemotherapy regimen that contained docetaxel, epirubicin, and cyclophosphamide prolonged the survival of patients with early breast cancer.</p

Cardiovascular Side Effects of Radiotherapy in Breast Cancer

The aim of the thesis was to study cardiovascular side effects of radiotherapy (RT) in breast cancer (BC). In a study base of 25,171 women with BC diagnosed 1970-2000, we found a statistically significant 12% increase of stroke, compared to the stroke incidence in the background population. A case-control study of 282 cases with BC followed by a stroke and 1:1 matched controls with BC but not stroke was performed. In women irradiated to internal mammary chain (IMC) and supraclavicular lymph nodes (SCL) vs. a pooled group of women not irradiated or irradiated to targets other than IMC and SCL, a statistically significant increase of stroke with an odds ratio of 1.8 was observed. There were no associations between BC laterality, targets of RT, and hemisphere location of stroke. The radiation targets IMC and SCL, showed a statistically significant trend for an increased risk of stroke with daily fraction dose. A study of 199 patients with BC, examined by coronary angiography, detected a four- to seven-fold increase of high grade coronary artery stenosis in mid and distal left anterior descending artery (LAD), including distal diagonal branch, when comparing women with irradiated left-sided BC to those with right-sided. An increase of clinically significant coronary artery stenosis was found in pre-specified hotspot areas for radiation among women irradiated to the left breast/chest wall or to the IMC. Thus, the coronary arteries should be regarded as organs at risk in RT of BC. In a study of 15 BC patients treated with 3D conformal RT, a marked difference in dose distribution in mid and distal LAD between left- and right-sided BC was demonstrated. Irradiated right-sided BC mainly received low doses of scattered and transmitted radiation to the coronary arteries. On the contrary, tangential RT to the left breast without regional lymph node irradiation yielded coronary artery max doses of approximately 50 Gray to distal LAD, probably not safe concerning late radiation vascular effects. To conclude, we found cardiovascular side effects in women irradiated for BC, resulting in stroke and coronary artery disease, and showed an association between the targets for RT and the anatomical location of these vascular events
