[Tardive akathisia after long-term metoclopramide treatment].

This case report describes a 57-year-old male with symptoms of tardive akathisia after long-term metoclopramide treatment. As metoclopramide is a dopamine receptor antagonist, it has the potential to cause drug-induced movement disorders, including akathisia, which is characterised by an inner restlessness resulting in a need for constant movement. Tardive akathisia, in contrast to acute akathisia, evolves after prolonged exposure to the triggering medication and can be a permanent condition.

Hypercortisolism in Newly Diagnosed Type 2 Diabetes: A Prospective Study of 384 Newly Diagnosed Patients.

Cross-sectional studies in small and selected populations report a high prevalence of hypercortisolism in patients with type 2 diabetes (T2D), which could have therapeutic implications, if confirmed. We therefore estimated the prevalence of hypercortisolism in a large and unselected cohort of recently diagnosed T2D patients. Consecutive patients with recently diagnosed T2D first underwent an overnight dexamethasone (1 mg) suppression test (OD).

Cushing's syndrome and pregnancy outcomes: a systematic review of published cases.

Pregnancy in Cushing's syndrome (CS) is extremely rare due to the influence of hypercortisolism on the reproductive axis. Purpose of this study is to investigate whether the etiology of CS in pregnancy determines a different impact on the fetal/newborn and maternal outcomes. We performed a systematic review of cases published in the literature from January 1952 to April 2015 including the words "Cushing AND pregnancy".

DIAGNOSIS OF ENDOCRINE DISEASE: Prevalence of hypercortisolism in type 2 diabetes patients: a systematic review and meta-analysis.

Objective: Type 2 diabetes (T2D) and Cushing's syndrome (CS) share clinical characteristics, and several small studies have recorded a high prevalence of hypercortisolism in T2D, which could have therapeutic implications. We aimed to assess the prevalence of endogenous hypercortisolism in T2D patients.

Design: Systematic review and meta-analysis of the literature.

Low positive predictive value of midnight salivary cortisol measurement to detect hypercortisolism in type 2 diabetes.

Background: Hypercortisolism is prevalent in type 2 diabetes (T2D), but analytical and functional uncertainties prevail. Measurement of salivary cortisol is considered an expedient screening method for hypercortisolism, but its usefulness in the context of T2D is uncertain.

Aim: To compare late-night salivary cortisol (LNSC) with the 1 mg overnight dexamethasone suppression test (DST), which was considered 'reference standard', in T2D.

[Acromegaly masked by symptomatic hyperprolactinaemia].

A 48-year-old woman presented with galactorrhoea, moderate hyperprolactinaemia (0.97 IU/l) and a pituitary macroadenoma (10 × 7 × 6 mm). Over a period of six years the patient had developed overt acromegalic features and was subsequently diagnosed with acromegaly while treated with dopamine receptor agonist.

[Dopamin agonist treatment and fibrotic heart valve disease in hyperprolactinaemia patients].

Treatment with dopamin agonists, particularly cabergoline, is the primary and preferred therapy for prolactinomas and symptomatic hyperprolactinaemia due to its effectiveness and tolerability. However, an association has been demonstrated between fibrotic heart valve disease and high-dose dopamin agonist use in patients with Parkinson's disease in several echocardiographic studies. Such observations have prompted a number of studies of valvular function in cabergoline-treated hyperprolactinaemia patients.

The Danish Centre for Strategic Research in Type 2 Diabetes (DD2) study: implementation of a nationwide patient enrollment system.

This paper aims to describe the patient enrollment system and implementation strategy for the new nationwide Danish Centre for Strategic Research in Type 2 Diabetes (DD2) project. The paper will also describe the design, current content, and pilot testing of the DD2 registration form. The challenge of the DD2 project was to construct a registration system functioning in the entire Danish health care system, where new type 2 diabetes patients are initially met, and with the capacity to enroll 200 newly diagnosed diabetes patients per week nationwide.

The Danish Centre for Strategic Research in Type 2 Diabetes (DD2) Project: rationale and planned nationwide studies of genetic predictors, physical exercise, and individualized pharmacological treatment.

Here we provide an overview of the rationale and methods of a series of planned population based studies within the Danish Centre for Strategic Research in Type 2 Diabetes (DD2) Project. The project aims to support and evaluate ongoing political and administrative efforts to implement nationwide guidelines for maintaining metabolic control in newly diagnosed type 2 diabetes (T2D) patients to prevent diabetic complications and improve quality of life. The DD2 is designed as a prospective cohort study (collection of epidemiological data) supplemented by randomized clinical intervention trials (on physical exercise and individualized pharmacological treatment) and the establishment of a biobank comprised of material from a large number of newly diagnosed T2D patients.

Heart valve disease among patients with hyperprolactinemia: a nationwide population-based cohort study.

Background: Increased risk of heart valve disease during treatment with certain dopamine agonists, such as cabergoline, has been observed in patients with Parkinson's disease. The same compound is used to treat hyperprolactinemia, but it is unknown whether this also associates with heart valve disease.

Objectives: The objective of the study was to assess the incidence of diagnosed heart valve disease and cardiac valve surgery among patients with hyperprolactinemia, compared with a general population cohort in Denmark.

Targeting amyloid-beta by glucagon-like peptide -1 (GLP-1) in Alzheimer's disease and diabetes.

Introduction: Epidemiological evidence suggests an association between type 2 diabetes (T2DM) and Alzheimer's disease (AD), in that one disease increases the risk of the other. T2DM and AD share several molecular processes which underlie the tissue degeneration in either disease. Disturbances in insulin signaling may be the link between the two conditions.

Epidemiology of Cushing's syndrome.

Overt Cushing's syndrome is a rare disorder with an annual incidence of 2-3/million of which benign adrenal adenomas account for 0.6/million. The female:male ratio is 3:1.

Modifications of amino acids during ferulic acid-mediated, laccase-catalysed cross-linking of peptides.

Mass spectral analysis demonstrated oligomerization of peptides that had been subjected to oxidation catalysed by Trametes (Coriolus) versicolor laccase. Peptide oligomerization occurred only when cysteines or tyrosines were present in the peptides. MS/MS confirmed the cross-linking in tyrosine-containing peptides to be located between tyrosine residues.

Cross-linking proteins by laccase-catalyzed oxidation: importance relative to other modifications.

Laccase-catalyzed oxidation was able to induce intermolecular cross-links in beta-lactoglobulin, and ferulic acid-mediated laccase-catalyzed oxidation was able to induce intermolecular cross-links in alpha-casein, whereas transglutaminase cross-linked only alpha-casein. In addition, different patterns of laccase-induced oxidative modifications were detected, including dityrosine formation, formation of fluorescent tryptophan oxidation products, and carbonyls derived from histidine, tryptophan, and methionine. Laccase-catalyzed oxidation as well as transglutaminase induced only minor changes in surface tension of the proteins, and the changes could not be correlated to protein cross-linking.

Comparison of the characteristics of fungal and plant tyrosinases.

Enzymatic crosslinking provides valuable means for modifying functionality and structural properties of different polymers. Tyrosinases catalyze the hydroxylation of various monophenols to the corresponding o-diphenols, and the subsequent oxidation of o-diphenols to the corresponding quinones, which are highly reactive and can further undergo non-enzymatic reactions to produce mixed melanins and heterogeneous polymers. Tyrosinases are also capable of oxidizing protein- and peptide-bound tyrosyl residues, resulting in the formation of inter- and intra-molecular crosslinks.

Laccase-catalyzed polymerization of tyrosine-containing peptides.

Laccase-catalyzed polymerization of tyrosine and tyrosine-containing peptides was studied in the presence and absence of ferulic acid (FA). Advanced spectroscopic methods such as MALDI-TOF MS, EPR, FTIR microscopy and HPLC-fluorescence, as well as more conventional analytical tools: oxygen consumption measurements and SDS/PAGE were used in the reaction mechanism studies. Laccase was found to oxidize tyrosine and tyrosine-containing peptides, with consequent polymerization of the compounds.

Significance of preslaughter stress and different tissue PUFA levels on the oxidative status and stability of porcine muscle and meat.

Polyunsaturated fatty acids (PUFAs) and exercise-induced stress are known to increase the oxidative susceptibility of lipids in muscle tissue. In contrast, antioxidative enzymes, e.g.

Aldehyde-induced xanthine oxidase activity in raw milk.

In the present study, the aldehyde-induced pro-oxidative activity of xanthine oxidase was followed in an accelerated raw milk system using spin-trap electron spin resonance (ESR) spectroscopy. The aldehydes acetaldehyde, propanal, hexanal, trans-2-hexenal, trans-2-heptenal, trans-2-nonenal, and 3-methyl-2-butenal were all found to initiate radical reactions when added to milk. Formation of superoxide through aldehyde-induced xanthine oxidase activity is suggested as the initial reaction, as all tested aldehydes were shown to trigger superoxide formation in an ultrahigh temperature (UHT) milk model system with added xanthine oxidase.

Chicken model for studying dietary antioxidants reveals that apple (Cox's Orange)/broccoli (Brassica oleracea L. var. italica) stabilizes erythrocytes and reduces oxidation of insoluble muscle proteins and lipids in cooked liver.

A chicken model for studying the effects of antioxidants in the diet on oxidative status was set up. Chickens fed a semi-synthetic diet low in antioxidants showed a remarkable decrease in erythrocyte stability toward H(2)O(2) or 2,2'-azobis (2-amidinopropane) dihydrochloride (AAPH), but increases in catalase activity in liver, carbonyls in insoluble muscle proteins, and enhanced lipid oxidation in heat-treated liver samples compared to that of conventionally fed chickens. Thus, this chicken model proved to be more susceptible to oxidative changes than conventionally fed chickens, reflecting a low antioxidative defense.

Myocellular triacylglycerol breakdown in females but not in males during exercise.

The resting content and use of myocellular triacylglycerol (MCTG) during 90 min of submaximal exercise [60% of peak oxygen uptake (VO(2 peak))] were studied in 21 eumenorrheic female and 21 male subjects at different training levels [untrained (UT), moderately trained (MT), and endurance trained (END)]. Males and females were matched according to their VO(2 peak) expressed relative to lean body mass, physical activity level, and training history. All subjects ingested the same controlled diet for 8 days, and all females were tested in the midfollicular phase of the menstrual cycle.

Gender differences in substrate utilization during submaximal exercise in endurance-trained subjects.

Substrate utilization across the leg during 90 min of bicycle exercise at 58% of peak oxygen uptake (VO(2 peak)) was studied in seven endurance-trained males and seven endurance-trained, eumenorrheic females by applying arteriovenous catheterization, stable isotopes, and muscle biopsies. The female and male groups were matched according to VO(2 peak) per kilogram of lean body mass, physical activity level, and training history of the subjects. All subjects consumed the same diet, well controlled in terms of nutrient composition as well as energy content, for 8 days preceding the experiment, and all females were tested in the midfollicular phase of the menstrual cycle.
