- What’s known on the subject? and What does the study add?Functional gastrointestinal symptoms and problems are common after radical cystectomy with urinary diversion. This study adds new important epidemiological data on this group of symptoms. OBJECTIVE: To describe and compare long-term defecation disturbances in patients who had undergone a cystectomy due to urinary bladder cancer with non-continent urostomies, continent reservoirs and orthotopic neobladder urinary diversions. PATIENTS AND METHODS: During their follow-up we attempted to contact all men and women aged 30–80 years who had undergone cystectomy and urinary diversion at seven Swedish hospitals. During a qualitative phase we identified defecation disturbances as a distressful symptom and included this item in a study-specific questionnaire together with free-hand comments. The patients completed the questionnaire at home. Outcome variables were dichotomized and the results are presented as relative risks with 95% confidence interval. RESULTS: The questionnaire was returned from 452 (92%) of 491 identified patients. Up to 30% reported problems with the physiological emptying process of stool (bowel movement, sensory rectal function, awareness of need for defecation, motoric rectal and anal function, straining ability). A sense of decreased straining capacity was reported by 20% of the men and women with non-continent urostomy and 14% and 8% of those with continent reservoirs and orthotopic neobladders, respectively. CONCLUSIONS: Of the cystectomized individuals 30% reported problems with the physiological emptying process of stool (bowel movement, sensory rectal function, awareness of need for defecation, motoric rectal and anal function, straining ability). Those wanting to improve the situation for bladder cancer survivors may consider communicating before surgery the possibility of stool-emptying problems, and asking about them after surgery.

- Objective: Describe and perform an initial test of a tailored treatment programme based on a behavioural medicine approach to enhance haemodialysis patients’ self-management of fluid restriction. Methods: Cognitive-behavioural techniques were used in four quasi-experimental case-studies. Central features in the programme were individual analysis of dietetic knowledge and fluid intake, setting goals, self-monitoring and prevention of relapse. Fluid overload was continuously assessed. Results: Acceptability and feasibility of the intervention were demonstrated. A clear reduction of fluid overload was shown. Some problems related to treatment fidelity were identified. Conclusion: The behavioural medicine approach resulted in reduction of fluid overload in each of the four cases included. Practice implications: This approach could be used as a method for tailoring interventions targeted to fluid intake behaviour in a heterogeneous group of HD patients with excessive fluid overload. Such treatment should take account of individual cognitive-behavioural patterns and include self-efficacy to low fluid intake. The efficacy of the tailored approach in regular practice has to be further tested in controlled trials.

- There is a need for high throughput methods for screening patient samples in the quest for potential biomarkers for diagnostics and patient care. Here, we used a combination of undirected target selection, antibody suspension bead arrays, and heat-induced epitope retrieval to allow for protein profiling of human plasma in a novel and systematic manner. Several antibodies were found to reveal altered protein profiles upon epitope retrieval at elevated temperatures with limits of detection improving into lower ng/ml ranges. In a study based on prostate cancer patients, several proteins with differential profiles were discovered and subsequently validated in an independent cohort. For one of the potential biomarkers, the human carnosine dipeptidase 1 protein (CNDP1), the differences were determined to be related to the glycosylation status of the targeted protein. The study shows a path of pursuit for large scale screening of biobank repositories in a flexible and proteome-wide fashion by utilizing heat-induced epitope retrieval and using an antibody suspension bead array format.

The Kidney in Different Stages of the Cardiovascular Continuum
- 2013

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Patients with chronic kidney disease are at higher risk of developing cardiovascular disease. The complex, interaction between the kidney and the cardiovascular system is incompletely understood, particularly at the early stages of the cardiovascular continuum.The overall aim of this thesis was to clarify novel aspects of the interplay between the kidney and the cardiovascular system at different stages of the cardiovascular continuum; from risk factors such as insulin resistance, inflammation and oxidative stress, via sub-clinical cardiovascular damage such as endothelial dysfunction and left ventricular dysfunction, to overt cardiovascular death.This thesis is based on two community-based cohorts of elderly, Uppsala Longitudinal Study of Adult Men (ULSAM) and Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS).The first study, show that higher insulin sensitivity, measured with euglycemic-hyperinsulinemic clamp technique was associated to improve estimated glomerular filtration rate (eGFR) in participants with normal fasting plasma glucose, normal glucose tolerance and normal eGFR. In longitudinal analyses, higher insulin sensitivity at baseline was associated with lower risk of impaired renal function during follow-up. In the second study, eGFR was inversely associated with different inflammatory markers (C-reactive protein, interleukin-6, serum amyloid A) and positively associated with a marker of oxidative stress (urinary F2-isoprostanes). In line with this, the urinary albumin/creatinine ratio was positively associated with these inflammatory markers, and negatively associated with oxidative stress.In study three, higher eGFR was associated with better endothelial function as assessed by the invasive forearm model. Further, in study four, higher eGFR was significantly associated with higher left ventricular systolic function (ejection fraction). The 5th study of the thesis shows that higher urinary albumin excretion rate (UAER) and lower eGFR was independently associated with an increased risk for cardiovascular mortality. Analyses of global model fit, discrimination, calibration, and reclassification suggest that UAER and eGFR add relevant prognostic information beyond established cardiovascular risk factors in participants without prevalent cardiovascular disease.Conclusion: this thesis show that the interaction between the kidney and the cardiovascular system plays an important role in the development of cardiovascular disease and that this interplay begins at an early asymptomatic stage of the disease process.

- Objectives The thrombin inhibitor dabigatran is mainly excreted by the kidneys. We investigated whether the recommended method for estimation of renal function used in the clinical trials, the Cockcroft-Gault (CG(old)) equation and the estimated glomerular filtration rate (eGFR) modification of diet in renal disease equation 4 (MDRD4), differ in elderly participants, resulting in erroneously higher dose recommendations of dabigatran, which might explain the serious, even fatal, bleeding reported. The renally excreted drugs gabapentin and valaciclovir were also included for comparison. Design A retrospective data simulation study. Participants Participants 65years and older included in six different studies. Main outcome measure Estimated renal function by CG based on uncompensated (old Jaffe' method) creatinine (CG(old)) or by MDRD4 based on standardised compensated P-creatinine traceable to isotope-dilution mass spectrometry, and the resulting doses. Results 790 participants (432 females), mean age (SD) 77.6 +/- 5.7years. Mean estimated creatinine clearance (eCrCl) by the CG(old) equation was 44.2 +/- 14.8ml/min, versus eGFR 59.6 +/- 20.7ml/min/1.73m(2) with MDRD4 (p<0.001), absolute median difference 13.5, 95% CI 12.9 to 14.2. MDRD4 gave a significantly higher mean dose (valaciclovir +21%, dabigatran +25% and gabapentin +37%) of all drugs (p<0.001). With MDRD4 58% of the women would be recommended a full dose of dabigatran compared with 18% if CG(old) is used. Conclusions MDRD4 would result in higher recommended doses of the three studied drugs to elderly participants compared with CG, particularly in women, and thus increased the risk of dose and concentration-dependent adverse reactions. It is important to know which method of estimation of renal function the Summary of Products Characteristics was based on, and use only that one when prescribing renally excreted drugs with narrow safety window. Doses based on recently developed methods for estimation of renal function may be associated with considerable risk of overtreatment in the elderly.

- Every year medical researchers make contact with a large number of cancer survivors with the aim of evaluating cancer treatment. For this reason we decided to investigate how Swedish cancer survivors perceived their participation in research studies focusing on the long-term consequences of being a survivor of gynaecological or urinary bladder cancer. Data were collected by means of two study-specific postal questionnaires, both consisting of questions covering physical symptoms, well-being and the experience of being a cancer survivor. Both questionnaires also included questions evaluating the participants' experience of being research subjects. The questionnaires were developed in close co-operation with cancer survivors. The study population consisted of 1068 cancer survivors. Of these, 95% (n=1003) reported that they thought the study was valuable and 54% (n=559) that they had been positively affected by participating. Four per cent (n=39) expressed that they had been negatively affected by their participation in the study. The vast majority of the cancer survivors thought that participating in their particular study was valuable.

- To compare ultrasound (US) scan and nuclear renography findings in patients who underwent pyeloplasty with and without pelvic reduction in a randomized prospective study.A total of 42 patients, all prenatally diagnosed with unilateral hydronephrosis, were included. Hydronephrosis was confirmed postnatally. Twenty patients were randomly selected to undergo pyeloplasty with pelvic reduction and 22 underwent pelvis-sparing pyeloplasty. Patients were evaluated with mercaptoacetyltriglycine-3 scans on the sixth month and US scans on the first, third, and sixth months, postoperatively. Mean follow-up was 37 +/- 5.6 weeks. Statistical analyses were performed using chi-square test and significance was set as P <.05. Power analyses were performed by the NCSS-PASS program. Power value of 0.84 was calculated for a sample size of 42.The anteroposterior pelvic diameter decreased significantly in the pelvic reduction group compared with pelvis-sparing group in the first- and third-month US scans. However, the difference was not significant in the sixth month. The improvements in the US findings for the pelvis-sparing group match with those of the pelvic reduction group later in the postoperative period. Pelvic reduction significantly improved the renal washout time (T(1/2)) in mercaptoacetyltriglycine-3 renography when compared with pyeloplasty group without reduction at postoperative sixth month. Differential renal function was found to be unaffected from pelvic reduction.Resolution of anteroposterior diameter in US scan is more prominent in the pelvic reduction group at earlier stages of the postoperative period. Although T(1/2) decreases more prominently in the pelvic reduction group, the utility of this procedure is still indecisive. This feature can reveal possible surgical failures earlier and strengthen the values of US and renography postoperatively.
