- Tularemia is a febrile disease caused by the highly contagious bacterium Francisella tularensis. We undertook an analysis of the transcriptional response in peripheral blood during the course of ulceroglandular tularemia by use of Affymetrix microarrays comprising 14,500 genes. Samples were obtained from seven individuals at five occasions during 2 weeks after the first hospital visit and convalescent samples 3 months later. In total, 265 genes were differentially expressed, 95 of which at more than one time point. The differential expression was verified with real-time quantitative polymerase chain reaction for 36 genes (R(2)=0.590). The most prominent changes were noted in samples drawn on days 2-3 and a considerable proportion of the upregulated genes appeared to represent an interferon-gamma-induced response and also a proapoptotic response. Genes involved in the generation of innate and acquired immune responses were found to be downregulated, presumably a pathogen-induced event. A logistic regression analysis revealed that seven genes were good predictors of the early phase of tularemia. This is the first description of the transcriptional host response to ulceroglandular tularemia and the study has identified gene subsets relevant to the pathogenesis of the disease and subsets that may serve as early diagnostic biomarkers.

- A qualitative study was conducted with the aim to describe family members' experiences, information needs and information seeking in relation to living with a patient suffering from oesophageal cancer. Data were collected by means of semi-structured interviews with nine family members. A content analysis was used in order to organize data. It was found that family members were not aware of the severe diagnosis and the illness caused intrusions on the family. The time following diagnosis family members' information seeking was low. They used interpersonal as well as mass media sources to obtain knowledge about and handle the uncertainty related to the illness. Some family members did not actively seek information. In conclusion, healthcare professionals are expected to improve quality of cancer care. These improvements are unlikely to occur without an understanding of family members' needs. This study shows that the family members were unprepared of receiving a diagnosis of oesophageal cancer. They emphasized the importance of including the children in the care given. Moreover, the whole family was faced with uncertainty, which led to intrusion on everyday life. Therefore, family members used different strategies for managing the uncertainty, whereof one was searching for information. The primary source of information was the physician.

- This pilot study was undertaken to describe patients' and family members' information needs following a diagnosis of oesophageal cancer and healthcare professionals' (HCP) perceptions concerning patients' and family members' information needs. Another aim was to describe patients' and family members' satisfaction with information provided. Data were collected by means of a self-report questionnaire. A total of 15 patients, 16 family members and 34 HCP participated. Patients and family members consider most information to be important. The high rating for information about tests/treatment and self-care means that both patients and family members consider this to be the most important areas of information. Healthcare professionals tend to underestimate both patients' and family members' needs for information. Patients and family members were only partly satisfied with the information received, with patients in general more satisfied with information given compared with family members. Patients' and family members' needs for information following a diagnosis of oesophageal cancer are substantial and have not been adequately met by HCP. A qualitative study might be helpful to complete the description of patients' and family members' needs. If a questionnaire is employed, it ought to be less extensive.

Life Situation, Information Needs, and Information Seeking in Patients with Oesophageal Cancer and their Family Members
- 2006

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis explores the experiences of living with oesophageal cancer from the perspective of patients and family members. Also, their needs for information and how they seek information in relation to the illness were investigated. The thesis comprises one qualitative meta-analysis and three empirical studies including data from patients, family members, and health-care professionals. Paper I was a qualitative meta-analysis the aim of which was to extend knowledge about patients' and family members' experiences of living with oesophageal cancer and clinically similar cancer forms, mainly head and neck cancer. As a result of the thematic analysis we have shown that both patients and family members 'run into an unpredictable enemy'. Patients had to 'endure a fading body' Running into an unpredictable enemy and enduring a fading body led to -entering social silence' for patients and family members.The aim of paper II was to describe patients' experiences of living with oesophageal cancer and how they seek information in relation to the illness. Data was collected by qualitative interviews with thirteen patients and analysed by qualitative content analysis. The findings describe patients' experiences of receiving the diagnosis, their experiences of vague symptoms, and of existential concerns evoked by the illness. Undergoing investigations and treatment caused extreme tiredness. Patients experienced that the illness intruded upon their daily life. In order to manage the life-threatening illness- they sought information about the illness.The aim of paper III was to describe family members' experiences of living with a patient suffering from oesophageal cancer, their information needs and information seeking Data was collected by means of qualitative interviews with nine family members and analysed by qualitative content analysis. The findings describe that family members lacked awareness of the disease. When faced with the diagnosis, shock, stress, and disbelief were evoked . The cancer illness became intrusive into their everyday lives, routines, and life plans. Uncertainty about the course and prognosis of the disease was the main source of distress among them. In order to learn, obtain understanding for the illness, and manage this uncertainty, family members entrusted themselves to the experts and sought information from them.Paper IV was a pilot study the aim of which was to describe patients' and family members' information needs following a diagnosis of oesophageal cancer, their satisfaction with information obtained, and health-care professionals' perceptions concerning patients' and family members' information needs. Data was collected by means of a study-specific questionnaire and analysed with descriptive statistics. The results indicate that patients' and family members need for information following a diagnosis of oesophageal cancer was substantial and had not been adequately met by health-care professionals.In conclusion, the receipt of the diagnosis of oesophageal cancer was an abrupt change from feeling healthy with vague symptoms to having a life-threatening illness. The illness disrupts patients' and family members' social world and relationships, and the whole family is affected. For understanding and managing the illness, they sought information from health-care professionals, social networks, and various media

- AIMS: The aim of this study is to describe patients' experiences of living with oesophageal cancer and how they seek information. BACKGROUND: Oesophageal cancer is a devastating disease with poor prognosis. Nursing care for individuals with oesophageal cancer requires increased knowledge of how they experience illness and how it affects them. METHOD: Data were collected by semi-structured, qualitative interviews with 13 participants. Content analysis was used to analyse data. RESULTS: Four themes were identified: (i) Experiences of becoming a patient diagnosed with oesophageal cancer is distinguished by the participants' experiences of vague symptoms, of receiving the diagnosis and of existential concerns evoked by the illness. (ii) Experiences of undergoing investigations and treatment consist of the participants' experiences of extreme tiredness in relation to investigations and treatment. (iii) Experiences of intrusions in daily life is conceptualized by the participants' experiences of how the illness influenced their daily life. (iv) Managing a life-threatening illness consists of a variety of strategies, which the participants employed to manage their life-threatening illness. CONCLUSIONS: The participants were unprepared of receiving a diagnosis of oesophageal cancer. Dysphagia, fatigue and uncertainty influenced the participants' everyday life. To manage the illness one of their strategies was seeking for information. The physicians were considered the main source of information, but family as well as friends with medical knowledge were also acknowledged as valuable sources. RELEVANCE TO CLINICAL PRACTICE: Understanding patients' experiences of living with oesophageal cancer is important to improve nursing care. When caring for these patients, focus ought to be on the whole family. In nursing care, it is important to be aware of the effects of dysphagia and fatigue. Health-care professionals ought to organize meetings with fellow patients and recommend literature and websites that provide patients with high quality information.

Early Risk Stratification, Treatment and Outcome in ST-elevation Myocardial Infarction
- 2005

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- We evaluated, in patients with ST-elevation myocardial infarction (STEMI) treated with thrombolytics, admission Troponin T (tnT), ST-segment resolution and admission N-terminal pro-brain natriuretic peptide (NT-proBNP) for early risk stratification as well as time delays and outcome in real life patients according to prehospital or in-hospital thrombolytic treatment. Also, baseline characteristics, treatments and outcome in patients enrolled in the ASSENT-2 trial in Sweden and in patients not enrolled were evaluated.TnT (n=881) and NT-proBNP (n=782) on admission and ST-resolution at 60 minutes (n=516) in patients from the ASSENT-2 and ASSENT-PLUS trials were analysed. Elevated levels of NT-proBNP and tnT on admission were both independently related to one-year mortality. However, when adding information on ST-resolution (We investigated consecutive STEMI patients included in the RIKS-HIA registry between 2001 and 2004, if they were ambulance transported and had received prehospital (n=1690) or in-hospital (n=3685) thrombolytic treatment. Prehospital diagnosis and thrombolysis reduced the time to thrombolysis by almost one hour, were associated with better left ventricular function and fewer complications and reduced the adjusted one-year mortality by 30% compared with in-hospital thrombolysis.Prospective data from the RIKS-HIA registry on STEMI patients treated with thrombolytics were linked to data on trial participants in the ASSENT-2 trial of thrombolytic agents and used for direct comparisons. Patients treated with thrombolytics and not enrolled in a clinical trial at trial hospitals (n=2048) had higher risk characteristics, more early complications and twice as high adjusted one-year mortality compared to those enrolled (n=729). One major reason for the difference in outcome appeared to be the selection of less critically ill patients to the trial.

- The glucocorticoid activating enzyme 11beta-hydroxysteroid dehydrogenase type 1 (11betaHSD1) is of major interest in obesity-related morbidity. Alterations in tissue-specific cortisol levels may influence lipogenetic and gluco/glyceroneogenetic pathways in fat and liver. We analyzed the expression and activity of 11betaHSD1 as well as the expression of phosphoenolpyruvate carboxykinase (PEPCK), sterol regulatory element binding protein (SREBP), and fatty acid synthase (FAS) in adipose and liver and investigated putative associations between 11betaHSD1 and energy metabolism genes. A total of 33 obese women (mean BMI 44.6) undergoing gastric bypass surgery were enrolled. Subcutaneous adipose tissue (SAT), omental fat (omental adipose tissue (OmAT)), and liver biopsies were collected during the surgery. 11betaHSD1 gene expression was higher in SAT vs. OmAT (P = 0.013), whereas the activity was higher in OmAT (P = 0.009). The SAT 11betaHSD1 correlated with waist circumference (P = 0.045) and was an independent predictor for the OmAT area in a linear regression model. Energy metabolism genes had AT depot-specific expression; higher leptin and SREBP in SAT than OmAT, but higher PEPCK in OmAT than SAT. The expression of 11betaHSD1 correlated with PEPCK in both AT depots (P = 0.05 for SAT and P = 0.0001 for OmAT). Hepatic 11betaHSD1 activity correlated negatively with abdominal adipose area (P = 0.002) and expression positively with PEPCK (P = 0.003). In human obesity, glucocorticoid regeneration in the SAT is associated with central fat accumulation indicating that the importance of this specific fat depot is underestimated. Central fat accumulation is negatively associated with hepatic 11betaHSD1 activity. A disturbance in peripheral glucocorticoid metabolism is associated with changes in genes involved in fatty acid (FA) recycling in adipose tissue (AT).
