Association of Osteoarthritis with Increased Risk of Cardiovascular Diseases in the Elderly: Findings from the Progetto Veneto Anziano Study Cohort
2015
Objective The possible relevance of osteoarthritis (OA) as a cardiovascular disease (CVD) risk factor is still debated. The aim of this study was to investigate the association between OA and the onset of CVD in older individuals. Methods Among a sample of 3,099 elderly subjects, 2,158 were identified as having no CVD at baseline and were followed up for a mean ± SD 4.4 ± 1.2 years. OA was defined using a standardized algorithm that investigated disease history, medical documentation (including radiographic reports), symptoms, and physical examination of the joints. Incident CVD was defined as the onset of coronary artery disease, heart failure, stroke/transient ischemic attack, peripheral …
First-episode psychosis and migration in Italy (PEP-Ita migration): A study in the Italian mental health services
2014
Abstract Background It has been frequently reported a higher incidence of psychotic disorders in immigrants than in native populations. There is, however, a lack of knowledge about risk factors which may explain this phenomenon. A better understanding of the causes of psychosis among first-generation migrants is highly needed, particularly in Italy, a country with a recent massive migration. Methods/Design The “Italian study on first-episode psychosis and migration (PEP-Ita)” is a prospective observational study over a two-year period (1 January 2012–31 December 2013) which will be carried out in 11 Italian mental health centres. All participating centres will collect data about all new cas…
Complement C1q is dramatically up-regulated in brain microglia in response to transient global cerebral ischemia.
2000
Abstract Recent evidence suggests that the pathophysiology of neurodegenerative and inflammatory neurological diseases has a neuroimmunological component involving complement, an innate humoral immune defense system. The present study demonstrates the effects of experimentally induced global ischemia on the biosynthesis of C1q, the recognition subcomponent of the classical complement activation pathway, in the CNS. Using semiquantitative in situ hybridization, immunohistochemistry, and confocal laser scanning microscopy, a dramatic and widespread increase of C1q biosynthesis in rat brain microglia (but not in astrocytes or neurons) within 24 h after the ischemic insult was observed. A marke…
The antibiotic erythromycin induces tolerance against transient global cerebral ischemia in rats (pharmacologic preconditioning).
2006
Background Cerebral ischemic tolerance can be induced by a variety of noxious stimuli, but no clinically applicable regimen for preconditioning has been described. Therefore, the authors tested the ability of a pharmacologic preconditioning strategy using the well-known macrolide antibiotic erythromycin to induce tolerance against transient global cerebral ischemia in vivo. They also investigated whether tolerance induction by erythromycin involves transcriptional and translational changes of cerebral B-cell leukemia/lymphoma-2 (bcl-2) expression. Methods Male Wistar rats were treated with erythromycin (25 mg/kg intramuscularly) or vehicle and subjected to 15 min of transient global cerebr…
High-sensitivity troponin assay improves prediction of cardiovascular risk in patients with cerebral ischaemia
2013
Background and purpose Clinical scores are recommended for predicting cardiovascular risk in patients with cerebral ischaemia to inform secondary prevention. Blood biomarkers may improve prediction beyond clinical scores. Methods Within the observational Find-AF trial (ISRCTN46104198), 197 patients >18 years of age with cerebral ischaemia and without atrial fibrillation had blood sampled at baseline. The predictive value of five biomarkers for a combined vascular endpoint (acute coronary syndrome, stroke, cardiovascular death) and all-cause mortality was determined, alone and in addition to the Essen Stroke Risk Score (ESRS), Stroke Prognostic Instrument 2 (SPI-2) and National Institutes of…
The Riga East University Hospital Stroke Registry—An Analysis of 4915 Consecutive Patients with Acute Stroke
2021
Background and Objectives: A hospital-based stroke registry is a useful tool for systematic analyses of the epidemiology, clinical characteristics, and natural course of stroke. Analyses of stroke registry data can provide information that can be used by health services to improve the quality of care for patients with this disease. Materials and Methods: Data were collected from the Riga East University Hospital (REUH) Stroke Registry in order to evaluate the etiology, risk factors, clinical manifestations, treatment, functional outcomes, and other relevant data for acute stroke during the period 2016–2020. Results: During a five-year period, 4915 patients (3039 females and 1876 males) with…
Neuroprotection and glutamate attenuation by acetylsalicylic acid in temporary but not in permanent cerebral ischemia.
2007
To assess the effects of acetylsalicylic acid (ASA) on glutamate and interleukin-6 (IL-6) release in the striatum of rats suffering from cerebral ischemia, we used the microdialysis technique with probes implanted 2 h prior to stroke onset. A total of 36 rats were randomly assigned to either temporary (90 min, n = 18) or permanent (n = 18) middle cerebral artery occlusion (MCAO). Animals received either a bolus of 40 mg/kg ASA or saline as control 30 min after stroke onset. Permanent MCAO led to large infarct volumes with no differences between treatment with ASA (239.8 ± 4.1 mm3) and saline (230.1 ± 3.9 mm3, p = 0.15). In contrast, ASA therapy in temporary ischemia (87.2 ± 6.2 mm3) reduced…
Reduction of infarct size by the NO donors sodium nitroprusside and spermine/NO after transient focal cerebral ischemia in rats
2000
Nitric oxide (NO) plays a dual role (neuroprotection and neurotoxicity) in cerebral ischemia. NO promoting strategies may be beneficial shortly after ischemia. Therefore, we have studied the hemodynamic and possible neuroprotective effects of two NO donors, the classical nitrovasodilator sodium nitroprusside (SNP) and the NONOate spermine/NO, after transient focal cerebral ischemia in rats. Parietal cortical perfusion was measured by laser-Doppler flowmetry. The effects of increasing intravenous doses (10-300 microgram) of sodium nitroprusside and spermine/NO on cortical perfusion and arterial blood pressure were assessed. Transient (2 h) focal cerebral ischemia was carried out by the intra…
Recommendation for ophthalmic care in German preschool health examination and its adherence: Results of the prospective cohort study ikidS.
2018
BackgroundEach child in Germany undergoes a preschool health examination including vision screening and recommendations for further ophthalmic care. This study investigated the frequency of and adherence to these recommendations.MethodsA population-based prospective cohort study was performed in the area of Mainz-Bingen (Rhineland-Palatinate, Germany). All preschoolers were examined at the statutory preschool health examination, which includes vision testing (Rodenstock vision screener) with available correction in the last preschool year. Based on the results, recommendations for further ophthalmic care were given to the parents. Six weeks prior to school entry, parents were surveyed conce…
Lysosomal storage disorder in non-immunological hydrops fetalis (NIHF) - more common than assumed? Report of four cases with transient NIHF and a rev…
2012
Abstract Background Lysosomal storage disorders (LSD) are a rare cause of non immunological hydrops fetalis (NIHF) and congenital ascites. The reported incidence is about 1%. The incidence of idiopathic NIHF is estimated to be about 18%. Patients and methods We report four cases with transient hydrops fetalis resulting from LSD and performed a literature review on LSD with NIHF and congenital ascites in combination. Results At present, 12 different LSDs are described to be associated with NIHF or congenital ascites. Most patients had a family history of NIHF, where the preceding sibling had not been examined. A diagnostic approach to the fetus with NIHF due to suspected LSD either in utero …
