  • Clinical characteristics and primary treatment of prostate cancer in Sweden between 1996 and 2005 : Data from the national prostate cancer register in Sweden
  • 2007

    • Objective. The incidence of prostate cancer is rising rapidly in Sweden and there is a need to better understand the pattern of diagnosis, tumor characteristics and treatment. Material and methods. Between 1996 and 2005, all new cases of adenocarcinoma of the prostate gland were intended to be registered in the National Prostate Cancer Register (NPCR). This register contains information on diagnosing unit, date of diagnosis, cause of diagnosis, tumor grade, tumor stage according to the TNM classification in force, serum prostate-specific antigen (PSA) levels at diagnosis and primary treatment given within the first 6 months after diagnosis. Results. In total, 72 028 patients were registered, comprising >97% of all pertinent incident cases of prostate cancer in the Swedish Cancer Register (SCR). During the study period there was a considerable decrease in median age at the time of diagnosis, a stage migration towards smaller tumors, a decrease in median serum PSA values at diagnosis, a decrease in the age-standardized incidence rate of men diagnosed with distant metastases or with a PSA level of >100 ng/ml at diagnosis and an increase in the proportion of tumors with Gleason score ≤6. Relatively large geographical differences in the median age at diagnosis and the age-standardized incidence of cases with category T1c tumors were observed. Treatment with curative intent increased dramatically and treatment patterns varied according to geographical region. In men with localized tumors and a PSA level of <20 ng/ml at diagnosis, expectant treatment was more commonly used in those aged ≥75 years than in those aged <75 years. Also, the pattern of endocrine treatment varied in different parts of Sweden. Conclusions. All changes in the register seen over time are consistent with increased diagnostic activity, especially PSA testing, resulting in an increased number of cases with early disease, predominantly tumors in category T1c. The patterns of diagnosis and treatment of prostate cancer vary considerably in different parts of Sweden. The NPCR continues to be an important source for research, epidemiological surveillance of the incidence, diagnosis and treatment of prostate cancer

  • The Antibacterial Chemokine MIG/CXCL9 Is Constitutively Expressed in Epithelial Cells of the Male Urogenital Tract and Is Present in Seminal Plasma.
  • 2008
  • Ingår i: Journal of Interferon and Cytokine Research. - : Mary Ann Liebert Inc. - 1079-9907 .- 1557-7465. ; 28:3, s. 190-196

    • ABSTRACT The integrity of the urogenital tract against potentially invasive pathogens is important for the health of the individual, fertilization, and continuance of species. Antibiotic peptides with broad antimicrobial activity, among them chemokines, are part of the innate immune system. We investigated the presence of the antibacterial interferon (IFN)-dependent CXC chemokines, MIG/CXCL9, IP-10/CXCL10, and I-TAC/CXCL11, in the human male reproductive system. MIG/CXCL9 was detected at 25.0 nM (range 8.1-40.6 nM; n = 14), whereas IP-10/CXCL10 and I-TAC/CXCL11 were detected at lower levels (mean 1.8 nM, range 0.3-5.8 nM and mean 0.6, 0.2-1.6 nM, respectively) in seminal plasma of fertile donors. The levels of MIG/CXCL9 are more than 300-fold higher than those previously reported in blood plasma. In vasectomized donors, significantly lower levels of MIG/CXCL9 (mean 14.7 nM, range 6.6-21.8) were found, suggesting that the testis and epididymis, in addition to the prostate, significantly contribute to the MIG/CXCL9 content of seminal plasma. Strong expression of MIG/CXCL9 was found in the epithelium of testis, epididymis, and prostate, as detected by immunohistochemistry. MIG/CXCL9 at concentrations in the order of those found in seminal plasma possessed antibacterial activity against the urogenital pathogen Neisseria gonorrhoeae. The relatively high levels of MIG/CXCL9 in seminal plasma point to roles for this chemokine in both host defense of the male urogenital tract and during fertilization.

  • Effectiveness of doxazosin in treatment of distal ureteral stones in children.
  • 2009
  • Ingår i: The Journal of urology. - : Ovid Technologies (Wolters Kluwer Health). - 1527-3792 .- 0022-5347. ; 182:6, s. 2880-4
  • Tidskriftsartikel (refereegranskat)abstract
    • We evaluated the effectiveness of doxazosin in children with distal ureteral stones in terms of stone expulsion rates and time to expulsion.A total of 39 patients 2 to 14 years old with lower ureteral stones smaller than 10 mm were enrolled and randomly divided into 2 groups. Group 1 consisted of 20 controls receiving ibuprofen for pain and group 2 consisted of 19 patients receiving doxazosin. Doxazosin dose was approximately 0.03 mg/kg daily. All patients were evaluated with x-ray, ultrasound or spiral computerized tomography. Stone expulsion rates and time to expulsion between the groups were compared. Mean followup was 19 days. Effects of doxazosin were also evaluated by comparing subgroups with stones smaller than 5 mm and 5 to 10 mm. Results were also evaluated with special emphasis on gender and age.Expulsion was observed in 14 patients (70%) in group 1 and 16 (84%) in group 2 (p >0.05). Mean expulsion times for groups 1 and 2 were 6.1 and 5.9 days, respectively (p >0.05). Although fewer pain episodes were observed in the treatment group, this finding could not be evaluated objectively. None of the patients experienced any adverse effects.Administration of 0.03 mg/kg doxazosin daily in children to treat distal ureteral stones up to 10 mm is not superior to analgesic alone. This result is not affected by gender, stone size or patient age. However, additional randomized controlled studies, especially including larger stone volumes, and different doses of doxazosin and other alpha-blockers, might highlight the usefulness of alpha-blockers for ureteral stones in children.

  • Low incidence of brain death and organ donation in Sweden. Analyses of a six-year prospective registration of all deceased patients in intensive units in Southern Sweden
  • 2006
  • Ingår i: Organs, Tissues and Cells. - 1828-0595. ; 9:1, s. 23-27
  • Tidskriftsartikel (refereegranskat)abstract
    • Sweden is among those countries in Europe that have the lowest number of organ donors per million population (PMP). Because of the low numbers of actual donors, it is important to identify the total number of potential donors. Thus, a prospective registration of all deceased patients at all intensive care units was introduced in the Southern Healthcare Region of Sweden, which has a population of 1.6 million. During the six years from 1999 to 2004, 3,760 deaths were recorded. Only 251 patients (7%) of all ages were diagnosed with brain death, corresponding to 26 patients PMP and year. Of these, 194 cases (20 PMP) were classified as potential organ donors, defined as brain death without medical contraindications against organ donation. Consent for organ donation was given in slightly more than half of these cases (54%) thus, there were only around 11 organ donors PMP and year. The continuous registration in Southern Sweden has been a very important tool for evaluation of what forms of action should be taken to promote organ donation. As part of a computerised system for quality assurance in intensive care now being introduced in many parts of Sweden, registration may become an instrument of quality assurance for organ donation nationwide.

  • Prostate-specific antigen at or before age 50 as a predictor of advanced prostate cancer diagnosed up to 25 years later: A case-control study
  • 2008
  • Ingår i: BMC Medicine. - : Springer Science and Business Media LLC. - 1741-7015. ; 6
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Based on a large, representative unscreened cohort from Malmo, Sweden, we have recently reported that a single prostate-specific antigen (PSA) measurement at or before age 50 is a strong predictor of prostate cancer occurring up to 25 years subsequently. We aimed to determine whether this association holds for advanced cancers, defined as clinical stage T3 or higher, or skeletal metastasis at the time of the cancer diagnosis. Methods: In 1974-1986 blood samples were obtained from a cohort of 21,277 men aged up to 50. Through 1999, 498 men were diagnosed with prostate cancer, and of these 161 had locally advanced or metastatic prostate cancers. Three controls, matched for age and date of venipuncture, were selected for each case. Conditional logistic regression was used to test associations between molecular markers and advanced cancer. Results: Median time from venipuncture to diagnosis was 17 years. Levels of all PSA forms and hK2 were associated with case status. Total PSA was a strong and statistically significant predictor of subsequent advanced cancer ( area under the curve 0.791; p < 0.0005). Two-thirds of the advanced cancer cases occurred in men with the top 20% of PSA levels (0.9 ng/ml or higher). Conclusion: A single PSA test taken at or before age 50 is a very strong predictor of advanced prostate cancer diagnosed up to 25 years later. This suggests the possibility of using an early PSA test to risk-stratify patients so that men at highest risk are the focus of the most intensive screening efforts.

  • Arterial remodeling and plasma volume expansion in caveolin-1 deficient mice.
  • 2007
  • Ingår i: American Journal of Physiology: Regulatory, Integrative and Comparative Physiology. - : American Physiological Society. - 0363-6119 .- 1522-1490. ; 293, s. 1222-1231

    • Caveolin- 1 ( Cav- 1) is essential for the morphology of membrane caveolae and exerts a negative influence on a number of signaling systems, including nitric oxide ( NO) production and activity of the MAP kinase cascade. In the vascular system, ablation of caveolin- 1 may thus be expected to cause arterial dilatation and increased vessel wall mass ( remodeling). This was tested in Cav- 1 knockout ( KO) mice by a detailed morphometric and functional analysis of mesenteric resistance arteries, shown to lack caveolae. Quantitative morphometry revealed increased media thickness and media- to- lumen ratio in KO. Pressure- induced myogenic tone and flow- induced dilatation were decreased in KO arteries, but both were increased toward wild- type ( WT) levels following NO synthase ( NOS) inhibition. Isometric force recordings following NOS inhibition showed rightward shifts of passive and active length- force relationships in KO, and the force response to alpha 1- adrenergic stimulation was increased. In contrast, media thickness and force response of the aorta were unaltered in KO vs. WT, whereas lumen diameter was increased. Mean arterial blood pressure during isoflurane anesthesia was not different in KO vs. WT, but greater fluctuation in blood pressure over time was noted. Following NOS inhibition, fluctuations disappeared and pressure increased twice as much in KO ( 38 +/- 6%) compared with WT ( 17 +/- 3%). Tracer- dilution experiments showed increased plasma volume in KO. We conclude that NO affects blood pressure more in Cav- 1 KO than in WT mice and that restructuring of resistance vessels and an increased responsiveness to adrenergic stimulation compensate for a decreased tone in Cav- 1 KO mice.
