Determinants of increasing pulse pressure during 23 years' follow-up as a marker of arterial stiffness and vascular ageing.

The aim was to investigate clinical characteristics of increased brachial pulse pressure (PP) during long-term follow-up (23 years) as a marker of arterial stiffness in 9704 healthy subjects. The association of baseline variables with an increasing PP burden during the study period was analysed by univariate analysis. In addition, the association between different biological variables at baseline

Modeling the cost-effectiveness of a new treatment for MS (natalizumab) compared with current standard practice in Sweden.

Objective To estimate the cost-effectiveness of a new treatment (natalizumab) for multiple sclerosis (MS) compared with current standard therapy with disease-modifying drugs (DMDs) in Sweden. Methods A Markov model was constructed to illustrate disease progression based on functional disability (the Expanded Disability Status Scale (EDSS)). The effectiveness of natalizumab was based on a 2-year cl

Fluorescence monitoring of a topically applied liposomal temoporfin formulation and photodynamic therapy of nonpigmented skin malignancies.

Meso-tetra(hydroxyphenyl)chlorin (mTHPC) (INN: Temoporfin) is a potent photodynamically active substance in clinical use today. Usually, the substance is given systemically and a known drawback with this administration route is a prolonged skin light sensitization. For the first time to our knowledge, a liposomal Temoporfin gel formulation for topical application was studied in connection with pho

Experimental poststreptococcal glomerulonephritis elicited by IgG Fc-binding M family proteins and blocked by IgG Fc fragment.

Burova L, Pigarevsky P, Seliverstova V, Gupalova T, Schalén C, Totolian A. Experimental poststreptococcal glomerulonephritis elicited by IgG Fc-binding M family proteins and blocked by IgG Fc fragment. APMIS 2012; 120: 221-30. The pathogenesis of acute poststreptococcal glomerulonephritis (APSGN), a major nonsuppurative complication of group A streptococcal (GAS) throat or skin disease, remains un

The clinical use of N-terminal-pro brain natriuretic peptide in elderly patients with mental illness.

BACKGROUND: Serum N-terminal-pro brain natriuretic peptide (NT-proBNP) is regarded as a marker of vascular disease and has previously been shown to exhibit an increased frequency of pathological values in elderly patients with mental illness with vascular disease compared to patients without vascular disease. Vascular disease plays an important role in cognitive impairment in elderly patients with

Ion Mobility Analysis of Lipoprotein Subfractions Identifies Three Independent Axes of Cardiovascular Risk.

OBJECTIVE: Whereas epidemiological studies show that levels of low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) predict incident cardiovascular disease (CVD), there is limited evidence relating lipoprotein subfractions and composite measures of subfractions to risk for CVD in prospective cohort studies. METHODS AND RESULTS: We tested whether combinations

Co-expression of C-terminal truncated alpha-synuclein enhances full-length alpha-synuclein-induced pathology.

Lewy bodies, which are a pathological hallmark of Parkinson's disease, contain insoluble polymers of alpha-synuclein (alphasyn). Among the different modifications that can promote the formation of toxic alphasyn species, C-terminal truncation is among the most abundant alterations in patients with Parkinson's disease. In vitro, C-terminal truncated alphasyn aggregates faster and sub-stoichiometric

The modified Ross operation using a Dacron prosthetic vascular jacket does prevent pulmonary autograft dilatation at 4.5-year follow-up.

Objective: Following the Ross operation, pulmonary autografts tend to dilate over time. This study researches the fate of the pulmonary autograft - at 4.5 years following the modified Ross operation - with special reference to the impact of the modification on (a) pulmonary autograft dilatation, (b) the neo-aortic root geometry, (c) neo-aortic valve function and (d) the coronary artery reserve. Me

Unpleasant and pleasant memories of intensive care in adult mechanically ventilated patients-Findings from 250 interviews.

AIM: In order to improve the patients' comfort and well-being during and after a stay in the intensive care unit (ICU), the patients' perspective on the intensive care experience in terms of memories is essential. The aim of this study was to describe unpleasant and pleasant memories of the ICU stay in adult mechanically ventilated patients. METHOD: Mechanically ventilated adults admitted for more

Kittinger and Baumgartner: on a mission to the edge of space

On 15 March 2012, Felix Baumgartner jumped from 71 500 feet [1], a test jump as part of his attempt to beat the earlier record set by Joe Kittinger, who jumped from 102 800 feet in 1960, as part of the US space programme [2] The ascent to these elevations in a helium balloon, followed by free fall, with varying temperatures and speed of sound, and increasing air resistance and density, can lead te

Improved label-free LC-MS analysis by wavelet-based noise rejection

Label-free LC-MS analysis allows determining the differential expression level of proteins in multiple samples, without the use of stable isotopes. This technique is based on the direct comparison of multiple runs, obtained by continuous detection in MS mode. Only differentially expressed peptides are selected for further fragmentation, thus avoiding the bias toward abundant peptides typical of da

Are Sulfonylureas Less Desirable Than DPP-4 Inhibitors as Add-on to Metformin in the Treatment of Type 2 Diabetes?

Sulfonylureas (SUs) are commonly used as add-on to metformin in treatment of type 2 diabetes in patients who are insufficiently controlled by metformin alone. They have good efficacy and have been shown to prevent microvascular complications. However, treatment with SUs is also associated with a high frequency of hypoglycemia, increased body weight, and a high risk of secondary failure. During rec

Diffusion and perfusion MRI of the brain in comatose patients treated with mild hypothermia after cardiac arrest: A prospective observational study.

BACKGROUND: Outcome for resuscitated cardiac arrest (CA) patients is poor. The 1-year survival rate with favourable neurological outcome (CPC 1-2) after out-of-hospital CA is reported to be 4%. Among resuscitated patients treated within an ICU, approximately 50% regain consciousness, whereas the other 50% remain comatose before they die. Induced hypothermia significantly improves the neurological

Maladaptive plasticity of serotonin axon terminals in levodopa-induced dyskinesia.

OBJECTIVE:: Striatal serotonin projections have been implicated in levodopa-induced dyskinesia by providing an unregulated source of dopamine release. We set out to determine whether these projections are affected by levodopa treatment in a way that would favor the occurrence of dyskinesia. METHODS:: As an index of terminal serotonin innervation density, we measured radioligand binding to the plas

Ventilation/Perfusion SPECT for Diagnosis of Pulmonary Embolism and Other Diseases.

V/P(SPECT) has the potential to become a first hand tool for diagnosis of pulmonary embolism based on standardized technology and new holistic interpretation criteria. Pretest probability helps clinicians choose the most appropriate objective test for diagnosis or exclusion of PE. Interpretation should also take into account all ventilation and perfusion patterns allowing diagnosis of other cardio
