The multimodal Munich Clinical Deep Phenotyping study to bridge the translational gap in severe mental illness treatment research.

Introduction: Treatment of severe mental illness (SMI) symptoms, especially negative symptoms and cognitive dysfunction in schizophrenia, remains a major unmet need. There is good evidence that SMIs have a strong genetic background and are characterized by multiple biological alterations, including disturbed brain circuits and connectivity, dysregulated neuronal excitation-inhibition, disturbed dopaminergic and glutamatergic pathways, and partially dysregulated inflammatory processes. The ways in which the dysregulated signaling pathways are interconnected remains largely unknown, in part because well-characterized clinical studies on comprehensive biomaterial are lacking.

In a randomised study, 28 patients with a mean age of 62.2 years (32 to 81) with osteoarthritis or avascular necrosis of the hip received either a ceramic-on-ceramic or a metal-on-metal total hip replacement. Apart from the liners the acetabular and femoral components were made of Ti-Al-Nb alloy.

Does the placenta inhibit the passage of chromium and cobalt after metal-on-metal total hip arthroplasty?

Umbilical cord serum and corresponding maternal serum of 3 women with uncemented metal-on-metal total hip arthroplasties were analyzed for cobalt and chromium. The women were an average 3.8 (range, 2-5) years after hip surgery.

Cup inclination and serum concentration of cobalt and chromium after metal-on-metal total hip arthroplasty.

We investigated whether cup inclination influences serum levels of cobalt and chromium after metal-on-metal total hip arthroplasty. Out of a consecutive series, 3 groups of 20 patients each were established according to their cup inclination: greatest inclination (55 degrees -63 degrees, mean 58 degrees), intermediate inclination (44 degrees -46 degrees, mean 45 degrees), and smallest inclination (23 degrees -37 degrees, mean 33 degrees). We did not detect any statistically significant difference of serum cobalt (P = .

Serum cobalt levels after metal-on-metal total hip arthroplasty.

Background: Systemic cobalt dissemination from the Metasul Co-28Cr-6Mo-0.2C metal-on-metal total hip prosthesis has been demonstrated in the first year after implantation. The aim of this prospective study was to monitor the serum cobalt concentrations in patients during the first five years after total hip arthroplasty with a metal-on-metal articulation.

Purpose: The influence of chronic renal failure on serum cobalt and serum chromium in two patients with metal-on-metal bearing (Metasul) and cementless total hip arthroplasty (Alloclassic) is investigated.

Methods: Serum cobalt and serum chronium levels were determined in the postoperative course using atomic absorption spectrometry.

Results: Maximum values are found to be more than 100-fold elevated when compared to the reported median serum cobalt concentrations in patients with the same prosthesis type and no known renal disease.

Elevated serum cobalt with metal-on-metal articulating surfaces.

We determined serum cobalt levels in 55 patients by atomic absorption spectrophotometry before and after implantation of uncemented total hip arthroplasties. In a randomised, prospective trial 27 wrought Co-28Cr-6Mo-0.2C metal-on-metal articulations were compared with 28 ceramic-on-polyethylene hips which did not contain cobalt.

Oral zinc and the second eye in age-related macular degeneration.

Purpose: To investigate the short-term effect of oral zinc substitution on the development of age-related macular degeneration in the second eye of patients with an exudative form of the disease in the first eye.

Methods: A 2-year, double-masked, randomized, placebo-controlled study including 112 white patients with age-related macular degeneration and exudative lesions (choroidal neovascularization, pigment epithelial detachment, or both) in one eye and a visual acuity of better than 20/40 and macular degeneration without any exudative lesion in the second eye was performed. Patients received either 200 mg of oral zinc sulfate or placebo once daily for 24 months.

Measurement of extracellular fluid carboplatin kinetics in melanoma metastases with microdialysis.

Clinical anti-tumour efficacy of anti-cancer drugs is a function of dose intensity, i.e. the concentration--time profile in tumour tissue.

Effect of lead on blood pressure in occupationally nonexposed men.

To determine if low-level exposure to lead has an effect on arterial blood pressure, demographic and clinical data of a group of 507 males without any occupational exposure to lead were analyzed in a retrospective study. The following variables were included in the analysis: age, height, weight, nicotine consumption, alcohol intake, blood lead, systolic blood pressure, diastolic blood pressure, and erythrocyte count. The effects of the variables age, weight, height, alcohol intake, nicotine consumption, and blood lead on blood pressure were investigated by stepwise linear regression analysis.

Zinc levels of serum and cervicovaginal secretion in recurrent vulvovaginal candidiasis.

Objective: To determine whether zinc deficiency in serum or vulvovaginal secretion is a risk factor for recurrent vulvovaginal candidiasis.

Design: Prospective and controlled study.

Setting: Department of Dermatology, University of Vienna.

[Lead, mercury and cadmium in newborn infants and their mothers].

The objective of the present study was to determine the toxic trace element status of 51 healthy Austrian women and their newborn babies. Lead, mercury and cadmium content of early breast milk, blood and urine were measured post partum by atomic absorption spectrophotometry. None of the toxic trace elements could be found in elevated concentrations; the content of mercury and cadmium in milk was below limits of detection.

[Neurologic symptoms in inhalation poisoning with metallic mercury].

Nineteen caisson workers had been exposed to metallic mercury vapours while digging tubes underneath the first district of Vienna (exposure between 470 and 2440 min; mean 1621 min). The blood mercury values on admission were between 29 and 166 micrograms/l (mean 75 +/- 34 micrograms/l).

Spontaneous and interferon-induced natural cytotoxicity in Crohn's disease.

Natural killer cell (NK) activity and antibody-dependent cellular cytotoxicity (ADCC) exerted by peripheral blood mononuclear cells (PMNC) were investigated in 53 patients with Crohn's disease (CD). NK activity and ADCC were found to be significantly reduced in patients with CD (p less than 0.0005) as compared to healthy controls.

[Heavy metal and trace element deviations. A comparison of idiopathic dilated cardiomyopathy and coronary heart disease].

Blood, serum and urine (24-hour-samples) concentrations of cadmium, zinc, calcium and magnesium were determined by means of atomic absorption spectrophotometry in 60 patients, therefrom 30 patients with idiopathic dilated cardiomyopathy (IDC) and 30 patients with coronary heart disease (CHD). The data of heavy metal and trace element concentrations of IDC and CHD patients were compared with each other and furthermore, for each group separately, correlated with patients history data, laboratory evaluations and data from heart catherization protocol. IDC patients showed higher blood cadmium concentrations (p less than 0.

Iron removal by desferrioxamine in patients on chronic hemodialysis--kinetic study and long-term results.

Serum ferritin levels, cumulative number of administered blood transfusions, number of monthly transfused blood units and total months on hemodialysis (HD) treatment differed significantly in 7 patients on hemodialysis with clinical, biochemical and histological evidence of hemosiderosis, when compared to 37 controls (p less than 0.001 for all parameters). As a new treatment method desferrioxamine (DFO) therapy was introduced for iron detoxification in these hemosiderotic chronically hemodialyzed patients.

Effect of desferrioxamine on aluminum kinetics during hemodialysis.

The effects of desferrioxamine administration on aluminum kinetics during hemodialysis were studied. Desferrioxamine leads to an increase of plasma aluminum levels in patients on chronic hemodialysis which could be attributed to mobilization of tissue aluminum. The in vivo protein binding of aluminum was found to be 70% after administration of desferrioxamine vs.
