Cost/benefit aspects on thromboprophylaxis

Several studies have shown thromboprophylaxis of any kind to be more cost-effective than no prophylaxis or general diagnostic surveillance and selective treatment. Little has been written on low molecular weight heparins from the cost-effectiveness point of view. This preliminary study shows low molecular weight heparin to be more cost-effective than standard low-dose heparin in most situations of

A detailed analysis of sodium removal by peritoneal dialysis: comparison with predictions from the three-pore model of membrane function

Background. The development of fluid and salt retention is a potential problem for all peritoneal dialysis (PD) patients. Sodium removal by the peritoneum is predominantly determined by convective fluid loss but influenced by diffusion and sieving due to free water transport as predicted by the three-pore model (TPM). The aim of the study was to establish the effect of transport status, dwell leng

Human papilloma virus in skin, mouth and uterine cervix in female renal transplant recipients with or without a history of cutaneous squamous cell carcinoma

Some human papilloma viruses are thought to be associated with skin cancer. In this pilot study, 21 female renal transplant carriers, 10 with a history of skin squamous cell carcinoma and 11 without, together with 9 age-matched healthy women were investigated for human papilloma virus DNA in sun-exposed (forehead) and less sun-exposed (buttock) skin, mouth and uterine cervix. Paraffin-embedded tum

Thyrostimulin (a TSH-like Hormone) Expression in Orbital and Thyroid Tissue.

Objective: To investigate gene expression of thyrostimulin in orbital and thyroid tissue from patients with and without Graves' disease. Design: Real-time reverse transcriptase polymerase chain reaction (RT-PCR) was used for detection of thyrostimulin gene expression in intraorbital adipose tissue from patients with severe ophthalmopathy and thyroid healthy controls in addition to thyrostimulin ex

Search for an LSP gluino at LEP with the DELPHI detector

In some supersymmetric models, the gluino ((g) over tilde) is predicted to be light and stable. In that case, it would hadronize to form R-hadrons. In these models, the missing energy signature of the lightest supersymmetric particle is no longer valid, even if R-parity is conserved. Therefore, such a gluino is not constrained by hadron collider results, which looked for the decay (g) over tilde -

A simple and effective procedure for the refinement of surface structure in LEED

A simple and effective procedure is described for the determination of the best-fit parameters of a given model of a surface structure by analysis of low energy electron diffraction (LEED) intensities. The procedure involves a nonlinear minimisation of chi(2) for the comparison of experimental and calculated intensities as a function of the parameters of the model structure. The minimisation is ca

The Effect of Transfer Port Geometry on Scavenge Flow Velocities At High Engine Speed

2-D LDV measurements were performed on two different cylinder designs in a fired two-stroke engine running with wide-open throttle at 9000 rpm. The cylinders examined were one with open transfer channels and one with cup handle transfer channels. Optical access to the cylinder was achieved by removing the silencer and thereby gain optical access through the exhaust port. No addition of seeding wa

System failure, innovation policy and patents: Fuel cells and related hydrogen technology in Norway 1990-2002

The empirical focus of this article is technological innovation activities in the emerging field of fuel cells and related hydrogen technology in Norway from 1990 to 2002. In this period, four comparatively large-scale research and development projects and a number of smaller projects aimed at development of fuel cells technology were undertaken, resulting in many inventions that were subsequently

Influence of antioxidants in virgine olive oil on the formation of heterocyclic amines in fried beefburgers.

An association between the intake of heterocyclic amines (HAs) and the development of cancer has been observed in some epidemiological studies, while in other studies no such correlation has been found. HAs are mutagenic/carcinogenic compounds formed at low levels via the Maillard reaction and a free radical mechanism during cooking of animal tissue. The addition of pure antioxidants or foods cont

A longitudinal study integrating population, care and social services data. The Swedish National study on Aging and Care (SNAC)

Background and aims: A large, national, long-term, longitudinal, multi-purpose study has been launched in Sweden - the Swedish National study on Aging and Care (SNAC). The study involves four research centers collecting data in four different areas of Sweden. Methods: The study consists of two parts: the population part and the care and services part. In the population part, a large, representativ

Similar group mean scores, but large individual variations, in patient-relevant outcomes over 2 years in meniscectomized subjects with and without radiographic knee osteoarthritis.

Background Epidemiological studies have, so far, identified factors associated with increased risk for incident or progressive OA, such as age, sex, heredity, obesity, and joint injury. There is, however, a paucity of long-term data that provide information on the nature of disease progression on either group or individual levels. Such information is needed for identification of study cohorts and

Long-term improvement of quality of life during growth hormone (GH) replacement therapy in adults with GH deficiency, as measured by questions on life satisfaction-hypopituitarism (QLS-H)

Questions on Life Satisfaction-Hypopituitarism (QLS-H) is a new quality-of-life (QoL) questionnaire developed for adults with hypopituitarism. To determine the effects of long-term GH treatment on QoL, we evaluated QLS-H Z-scores in 576 adult patients with GH deficiency (GHD) enrolled in HypoCCS, an international observational study, using data from five countries in which comparative QLS-H data f
