Prophylaxis of venous thromboembolism in elderly patients with multimorbidity
2013
none 327 si Pharmacological thromboprophylaxis (TP) is known to reduce venous thromboembolism (VTE) in medical inpatients, but the criteria for risk-driven prescription, safety and impact on mortality are still debated. We analyze data on elderly patients with multimorbidities admitted in the year 2010 to the Italian internal medicine wards participating in the REPOSI registry to investigate the rate of TP during the hospital stay, and analyze the factors that are related to its prescription. Multivariate logistic regression, area under the ROC curve and CART analysis were performed to look for independent predictors of TP prescription. Association between TP and VTE, bleeding and death in …
Contralateral increase in thigmotactic scanning following unilateral barrel-cortex lesion in mice.
2005
Adult C57BL/6 mice received uni- or bilateral cryogenic or sham-lesions over the barrel field and their exploratory behaviour was assessed in an open field between 1 and 7 days post-lesion. Bilateral cortical lesions produced a short-lasting increase in thigmotactic scanning with both sides of the face on the first day of testing. Mice with a unilateral barrel-cortex lesion showed more contralateral wall scanning with a recovery to behavioural symmetry after 5-7 days. Furthermore, the increase in contralateral thigmotaxis was most pronounced in animals with damage to the left barrel field, indicative of a lateralization of the lesion-induced behavioural changes. The cortical lesions did not…
Further Delineation of Duplications of ARX Locus Detected in Male Patients with Varying Degrees of Intellectual Disability
2022
The X-linked gene encoding aristaless-related homeobox (ARX) is a bi-functional transcription factor capable of activating or repressing gene transcription, whose mutations have been found in a wide spectrum of neurodevelopmental disorders (NDDs); these include cortical malformations, paediatric epilepsy, intellectual disability (ID) and autism. In addition to point mutations, duplications of the ARX locus have been detected in male patients with ID. These rearrangements include telencephalon ultraconserved enhancers, whose structural alterations can interfere with the control of ARX expression in the developing brain. Here, we review the structural features of 15 gain copy-number variants …
Vitamin D Receptor Activation Reduces Angiotensin-II–Induced Dissecting Abdominal Aortic Aneurysm in Apolipoprotein E–Knockout Mice
2015
Objective— Abdominal aortic aneurysm (AAA) is a vascular disorder characterized by chronic inflammation of the aortic wall. Low concentrations of vitamin D 3 are associated with AAA development; however, the potential direct effect of vitamin D 3 on AAA remains unknown. This study evaluates the effect of oral treatment with the vitamin D 3 receptor (VDR) ligand, calcitriol, on dissecting AAA induced by angiotensin-II (Ang-II) infusion in apoE −/− mice. Approach and Results— Oral treatment with calcitriol reduced Ang-II–induced dissecting AAA formation in apoE −/− mice, which was unrelated to systolic blood pressure or plasma cholesterol concentrations. Immunohistochemistry and reverse-tran…
Postoperative endophthalmitis incidence after intravitreal therapy: a comparison of two different preoperative antibiotic prophylaxis.
2016
Prevention of postoperative endophthalmitis (POE) is a goal of every ophthalmic procedure and also in intravitreal therapy (IVT). This comparative retrospective study targets whether systemic and topical preoperative antibiotic prophylaxis (PAP) regimen does prevent POE after IVT in a higher rate compared with topical PAP alone. Out of 6111 IVT performed over a period of 103.5 months, in the study group A patients were treated with systemic and topical PAP (2881 IVT), and in the study group B patients were treated only with topical PAP (3230 IVT). Intravitreal drugs were anti-VEGF, triamcinolone and dexamethasone implants. The incidence of POE in group A (1/2881 or 0.035 % per injection) wa…
Prevalence of intestinal parasites among inmates in Midwest Brazil.
2017
Made available in DSpace on 2018-11-26T17:40:54Z (GMT). No. of bitstreams: 0 Previous issue date: 2017-09-21 Fundacao de Desenvolvimento, Ensino, Ciencia e Tecnologia do Estado de Mato Grosso do Sul (FUNDECT) Background Intestinal parasitic infections constitute a public health issue in developing countries, with prevalence rates as high as 90%, a figure set to escalate as the socioeconomic status of affected populations deteriorates. Investigating the occurrence of these infections among inmates is critical, since this group is more vulnerable to the spread of a number of infectious illnesses. Methods This cross-sectional, analytical, quantitative study was conducted in July 2015 at prison…
Endophthalmitis after intravitreal injections: incidence, presentation, management, and visual outcome
2015
Purpose To report the incidence and characteristics of endophthalmitis after intravitreal injections of anti–vascular endothelial growth factor agents or corticosteroids and to describe the clinical and bacteriologic characteristics, management, and outcome of these eyes with acute endophthalmitis in France. Design Retrospective, nationwide multicenter case series. Methods From January 2, 2008 to June 30, 2013, a total of 316 576 intravitreal injections from 25 French ophthalmic centers were included. For each center, the number of intravitreal injections was determined using billing codes and the injection protocol was recorded. A registry and hospital records were reviewed to identify pat…
Behavioural and physiological effects of the trophically transmitted cestode parasite, Cyathocephalus truncatus, on its intermediate host, Gammarus p…
2007
SUMMARYSome parasites with complex life-cycles are able to manipulate the behaviour of their intermediate hosts in a way that increases their transmission to the next host. Gammarids infected by the tapeworm Cyathocephalus truncatus (Cestoda: Spathebothriidea) are known to be more predated by fish than uninfected ones, but potential behavioural manipulation by the parasite has never been investigated. In this study, we tested the hypothesis that C. truncatus is able to manipulate the behaviour of one of its intermediate hosts, Gammarus pulex (Crustacea: Amphipoda). To assess if any behavioural change was linked to other phenotypic alterations, we also measured the immunity of infected and u…
The role of antibiotic prophylaxis in reducing bacterial contamination of autologous bone graft collected from implant site
2017
The aim of this study was to evaluate if antibiotic prophylaxis reduces the bacterial contamination of bone particles collected directly from the burs used for implant site preparation. Thirty-four patients underwent the surgical procedures for a total of 34 implant sites. One 1 gr. tablet of amoxicillin + clavulanic acid was given to the test group 12 hours and 1 hour before the surgery. The control group did not take antibiotic prophylaxis. Bone particles were collected and centrifuged. The suspensions were subjected to serial dilutions and each dilution was examined twice using a spatulation technique in Trypticase Soy Agar (TSA), in Sabouraud Dextrose Agar, and in Mitis Salivarius Agar …
Low dose of aPCC after the initial treatment in acquired haemophilia A is useful to reduce bleeding relapses: Data from the FAIR registry
2019
Background: Bypassing agents are the first line therapy in patients with acquired haemophilia A (AHA). Activated prothrombin complex concentrate (aPCC) proved to be effective as initial treatment, but 20% of patients (pts) had relapses. aPCC as short-term prophylaxis to reduce subsequent bleeds is still not clear. Aim: To evaluate whether a short-term prophylaxis with low dose of aPCC can reduce bleeding relapses after initial AHA treatment, maintaining safety. Methods: The FAIR Registry is a retrospective-prospective study started on December 2012, that collected data on all pts with AHA treated with aPCC in 12 Italian Haemophilia Centers. All statistical analyses were carried out in the 5…
