BACKGROUND: Thrombin activation measured by the levels of the complex between activated protein C (APC) and the protein C inhibitor (PCI) is elevated in several atherosclerotic disorders. The aim of this study was to evaluate whether levels of the APC-PCI complex are related to the prognosis in peripheral arterial disease (PAD). Longitudinal study performed at the Vascular Centre, Malmö University
Rationale, aims and objectives The aim of this study was to compare acute hospital utilization and costs for patients with refractory angina pectoris undergoing spinal cord stimulation (SCS) versus enhanced external counterpulsation (EECP). Method Seventy-three persons were included in this register study. The acute hospital utilization and costs for SCS and EECP were followed over a period from 1
Because of the inexact nature of visual classification schemes and the resulting uncertainties of specifying raw material origins, geochemical methods applicable for sourcing Scandinavian flint have been sought. The authors have shown that EDXRF analysis yields geochemical data sufficiently precise and accurate to discriminate among many different varieties of archaeologically significant flint. H
Study Type - Diagnostic (exploratory cohort) Level of Evidence 2b OBJECTIVES: To assess variation of total prostate-specific antigen (tPSA), free PSA (fPSA), percent fPSA, human glandular kallikrein 2 (hK2) and intact PSA measured three times within 2 weeks. Knowledge of the variation in an individual's PSA level is important for clinical decision-making. PATIENTS AND METHODS: Study participants w
Background: Tumour hypoxia is a common characteristic of many solid human tumours, and is associated with a poor prognosis in various types of cancer. Metabolic changes occur when cells are exposed to low oxygen pressure; however, little is known about the mechanisms underlying malignant transformation and/or progression caused by hypoxia. Materials and Methods: We monitored global gene expression
Individuals diagnosed with schizophrenia show deficiencies of basic neurophysiological sorting mechanisms. This study further investigated this issue, focusing on the two phenomena laterality of coding and auditory forward masking. A specific audiometric method for use in psychiatry was the measuring set up to register brain stem audiograms (ABRs). A sample of 49 schizophrenic patients was compare
This paper introduces a new replenishment policy for inventory control in a two-level distribution system consisting of one central warehouse and an arbitrary number of nonidentical retailers. The new policy is designed to control the replenishment process at the central warehouse, using centralized information regarding the inventory positions and demand processes of all installations in the syst
OBJECTIVES: Testicular germ-cell cancer (TGCC) patients are at risk of developing hypogonadism but no risk factors have yet been defined. METHODS: Blood was collected from 143 TGCC patients (after orchidectomy, prior to further therapy (T0) and 6, 12, 24, 36 and 60 months (T6, T12, T24, T36 and T60) after therapy). Biological hypogonadism (BH) was defined as: serum testosterone below 10 nmol/l and
A common requirement of statistical methods, critical to the interpretation of the data, is that the analyzed observations are independent. This is not always the case in experiments and clinical studies, a mistake which can be expected to lead to erroneous study results. The phenomenon is explained, its consequences described, and suggestions to avoid the problems presented.
Using an in-house developed ultrasonic method, we have shown that there is distinct longitudinal multiphasic displacement of the human common carotid artery (CCA) wall during the cardiac cycle. Different subjects showed markedly different patterns of displacement. At present, it is not known if the pattern of displacement in an individual is stable over time. Therefore, in this study, we measured
Objective: To follow up bone mineral density (BMD) 4 years after decreased BMD was diagnosed in adult individuals with teenage-onset anorexia nervosa (AN). Method: In a previous study BMD was assessed in 39 individuals (36 women, 3 men) 11 years after AN onset. Decreased BMD occurred in a minority. In the present study, a 4-year follow-up of individuals with decreased BMD, 11 AN women were reass
Background/Aims: Experimental studies have suggested that trypsinogen may enhance tumor progression and that the ratio between anionic trypsinogen and cationic trypsinogen (HAT/HCT) and between the sum of trypsinogens and pancreatic secretory trypsin inhibitor (PSTI) ((HAT + HCT)/PSTI) are disturbed in patients with pancreatic cancer. The aim of this study was to investigate if pre-diagnostic leve
We have previously reported that COMP (cartilage oligomeric matrix protein) is prominent in cartilage but is also present in tendon and binds to collagens I and II with high affinity. Here we show that COMP influences the fibril formation of these collagens. Fibril formation in the presence of pentameric COMP was much faster, and the amount of collagen in fibrillar form was markedly increased. Mon
The pathogenesis of prostate cancer is unclear, although experimental evidence implicates androgens as playing an important role. Infertile men frequently suffer from some degree of hypogonadism and may hence be hypothesized to be at lower risk of developing prostate cancer than fertile men. To test this hypothesis, we conducted a case-control study nested within "the Malmö Diet and Cancer Study"
Background: Levosimendan has been proposed as an attractive alternative to adrenergic agents for the treatment of sepsis-induced heart failure and haemodynamic derangements. Its use in this setting is, however, still not well investigated. The aim of this study was to test the hypothesis that levosimendan is able to attenuate endotoxin-induced pulmonary hypertension and improve myocardial function
BACKGROUND: The CHADS(2) score (C, congestive heart failure [CHF]; H, hypertension [HT]; A, age ≥75 y; D, diabetes mellitus; S(2) , prior stroke or transient ischemic attack) is used to assess the risk of ischemic stroke in patients with atrial fibrillation (AF). However, its role in patients without documented AF is not well explored. HYPOTHESIS: The goal of the current study was to explore if th
