- AIM: This retrospective study evaluated long-term effects of percutaneous transluminal renal angioplasty (PTRA) in atherosclerotic renal artery stenosis (ARAS), and predictors of benefit on blood pressure (BP). METHODS: During 1997-2003, 234 patients (age 69+/-11 years, 138 [59%] males) underwent PTRA for ARAS at Malmö Vascular Centre. Cure was defined as diastolic (D)BP<90 mmHg and systolic (S)BP <140 mmHg off antihypertensive medication. Improvement was defined as DBP <90 mmHg and/or SBP <140 mmHg on the same or reduced number of medications, or reduction in DBP of 15 mmHg with the same or reduced number of medications. Benefit was defined as cure or improvement. RESULTS: After PTRA, SBP and DBP decreased (P<0.001), and remained lower (P<0.001) until last follow-up after 4.1+/-3.3 years. Antihypertensive medication decreased (P<0.001), and remained lower at one month (P<0.001), one year (P<0.01), and last follow-up (P<0.05). Renal function was unchanged until last follow-up, when it deteriorated (P<0.001). Patients showing benefit of PTRA on BP at last follow-up (N.=150 [64%]) used more antihypertensive drugs before PTRA (P=0.012), especially angiotensin converting enzyme inhibitors (ACEi) or angiotensin II receptor blockers (ARBs) (P=0.010), and diuretics (P=0.015). In logistic regression, use of ACEi or ARBs failed to reach significancy (P=0.054). Patients dying during follow up (N.=100 [43%]) showed higher age (P<0.0001) and s-creatinine (P<0.0001), lower glomerular filtration rate (P<0.0001), and higher frequency of diabetes mellitus (P<0.005). In logistic regression only age (P=0.009) and diabetes mellitus (P=0.014) predicted mortality. CONCLUSIONS: We confirmed beneficial effects on BP with PTRA in ARAS. ACEi, ARB and diuretic treatment before PTRA predict favourable long-term BP-response in univariate analysis.

- OBJECTIVE: To examine prospectively whether inflammatory biomarkers and endothelin (ET)-1 are increased in patients with renal artery stenosis (RAS), and to investigate how treatment with percutaneous transluminal renal angioplasty (PTRA) affects these variables during the first month after intervention. METHODS: One hundred patients with suspected RAS undergoing renal angiography were included. PTRA was performed if the trans-stenotic mean arterial pressure gradient was>or=10 mmHg. High-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNFalpha), neopterin, CD40 ligand (CD40L) and endothelin-1 (ET-1) were measured before, and 1 day and 1 month after PTRA (n=61) or diagnostic angiography only (n=39). RESULTS: At baseline there were no significant differences in inflammatory biomarkers or ET-1 levels between patients subsequently undergoing PTRA or angiography only. After angiography, IL-6 and hs-CRP had increased in both groups compared to baseline (P<0.001). At this time point hs-CRP (10.90+/-1.48 versus 6.37+/-1.61 mg/l; P<0.05) and IL-6 (13.70+/-0.94 versus 13.00+/-0.17 pg/ml; P<0.01) were higher in the PTRA group than in patients subjected to angiography only. One month after PTRA, systolic blood pressure and levels of IL-6 and ET-1 were lower than before intervention (P<0.05), whereas CD40L had increased compared to baseline (P<0.01). CONCLUSION: In patients with RAS, PTRA triggers rapid transient increases in hs-CRP and IL-6; however, 1 month after PTRA, both IL-6 and ET-1 had decreased compared to before intervention, indicating beneficial effects of PTRA on inflammation and the endothelin system.

- Fibromuscular dysplasia (FMD) mainly affects renal arteries. Percutaneous transluminal renal angioplasty (PTRA) and surgery are effective treatments, but longtime follow-up is lacking. Retrospective follow-up for 7.0 +/- 4.7 years of 69 consecutive patients ( age 44 +/- 13 years) treated for hypertension due to FMD, 59 patients underwent PTRA and eight patients surgery. In two patients no PTRA was performed. Technical success was achieved in 56 (95%) patients undergoing PTRA and all eight undergoing surgery. After successful PTRA, both systolic and diastolic blood pressures (SBP and DBP) had decreased at discharge ( from 174 +/- 33/ 100 +/- 13 to 138 +/- 19/80 +/- 15 mmHg; P<0.0001), and remained lower at 1 month, 1 year, and last follow-up after 7.0 +/- 4.7 years (140 +/- 25/83 +/- 12 mmHg; P<0.0001). Serum-creatinine had decreased both at 1 year ( from 84 +/- 28 to 75 +/- 13 mu mol/ l; P = 0.0030) and last follow-up (75 +/- 16 mu mol/ l; P = 0.0017). The number of antihypertensive drugs decreased ( from 2.3 +/- 1.2 before PTRA to 1.4 +/- 1.3 at discharge and at 1 month; P<0.0001, and 1.6 +/- 1.5 at last follow-up; P = 0.0011). SBP decreased more after PTRA among patients with FMD only in the main renal artery than in those with branch artery involvement (43 +/- 29 vs 20 +/- 41 mmHg; P = 0.0198). Beneficial effects on BP, creatinine and antihypertensive drugs also occurred after surgery. Patients on antihypertensive drugs at last follow-up had longer hypertension duration before PTRA than those without (5.9 +/- 7.7 vs 1.8 +/- 4.1 years; P = 0.0349). Cure was achieved in 16 (24%), improvement in another 26(39%), and benefit in 42(63%). In conclusion, renal artery FMD, PTRA and surgery have beneficial long-term effects, negatively affected by hypertension duration and branch artery involvement.

- All 74 patients treated with vena cava filter insertion during 1991-2000 at Malmo University Hospital were reviewed. Thirty-nine patients (53%) died during follow-up. Indications for permanent filter insertion (n = 63, age 25-89 years, 35 men) were contraindication for or side effects of anticoagulant treatment, or pulmonary embolism during anticoagulant treatment. Temporary vena cava filters (n = 11, age 19-85 years, three men) were inserted during surgery or thrombolysis. No complications occurred during temporary filter insertion. During 33 (1-120) months of follow-up of patients with permanent vena cava filters 37 patients (59%) died, thrombosis of the inferior vena cava occurred in 14 patients (22%), and recurrent pulmonary embolism in five patients (8%). Vena cava filter insertion should be considered as an alternative treatment in a selected group of patients with contraindications to or insufficient effect of anticoagulant treatment.

- This study is part of a research programme of which the aim is to generate knowledge about patients' and family members' experiences of living with oesophageal cancer from their perspective. The aim of the present study was to extend this knowledge by adding other forms of cancer: other upper gastrointestinal cancer, and head and neck cancer. These cancer forms have clinical similarities with oesophageal cancer and the survival rates are similar. This study is a qualitative meta-analysis that examines the results reported in 13 qualitative original research reports, published in peer-reviewed nursing journals between April 1998 and June 2006. We used thematic analysis. Three themes were formulated: “running into an unpredictable enemy”, “enduring a fading body” and “entering social silence”. Patients and family members gave voice to a suffering that involved the whole person. Our findings show that the whole person must be given care, and this care must include the whole family

- 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.

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.
