SU-FF-T-329: Monte Carlo Dosimetric Study of the Flexisource Ir-192 HDR Source
2006
Purpose:Brachytherapy with high dose rate (HDR) sources of 192 Ir is a usual practice in clinical brachytherapy today. The TG43 U1 update report recommends that accurate dose distribution data of the brachytherapysource in use should be obtained experimentally or by Monte Carlo (MC), to be used as input in the HDR Treatment Planning System (TPS). The purpose of this study is to obtain the dose rate distribution in liquid water media for the Flexisource HDR 192 Ir source (Isodose Control GmbH, Germany) using the Monte Carlo method to obtain the TG43 U1 parameters and the 2‐D rectangular dose rate table. Material and methods: The MC code GEANT4 (7.1 version) was used to estimate dose rate in …

Efficacy of amoxicillin and amoxicillin/clavulanic acid in the prevention of infection and dry socket after third molar extraction: a systematic revi…
2016
Background: Prophylactic use of amoxicillin and amoxicillin/clavulanic acid, although controversial, is common in routine clinical practice in third molar surgery. Material and Methods: Our objective was to assess the efficacy of prophylactic amoxicillin with or without clavulanic acid in reducing the incidence of dry socket and/or infection after third molar extraction. We conducted a systematic review and meta-analysis consulting electronic databases and references in retrieved articles. We included double-blind placebo-controlled randomized clinical trials published up to June 2015 investigating the efficacy of amoxicillin with or without clavulanic acid on the incidence of the aforement…
Training Psychiatry Residents in Descriptive Psychopathology: A Systematic Review
2021
<b><i>Purpose:</i></b> Descriptive psychopathology (DP, sometimes called psychopathology or phenomenology) is the language of psychiatry and is dedicated to the description of mental symptoms. Due to its importance, there is an ongoing case to put it back at the heart of psychiatry and its training. This study seeks to examine the literature on how to train psychiatry residents in DP, including reported educational interventions and educational methods. <b><i>Method:</i></b> The authors conducted a systematic review following the PRISMA and BEME guidelines to identify literature on how to train psychiatry residents in DP. In May 2019, they sea…
Air pollution exposure during pregnancy and reduced birth size: a prospective birth cohort study in Valencia, Spain
2010
Abstract Background Maternal exposure to air pollution has been related to fetal growth in a number of recent scientific studies. The objective of this study was to assess the association between exposure to air pollution during pregnancy and anthropometric measures at birth in a cohort in Valencia, Spain. Methods Seven hundred and eighty-five pregnant women and their singleton newborns participated in the study. Exposure to ambient nitrogen dioxide (NO2) was estimated by means of land use regression. NO2 spatial estimations were adjusted to correspond to relevant pregnancy periods (whole pregnancy and trimesters) for each woman. Outcome variables were birth weight, length, and head circumf…
Assessment and management of agitation in psychiatry: Expert consensus
2016
International audience; BACKGROUND:Psychomotor agitation is associated with different psychiatric conditions and represents an important issue in psychiatry. Current recommendations on agitation in psychiatry are not univocal. Actually, an improper assessment and management may result in unnecessary coercive or sedative treatments. A thorough and balanced review plus an expert consensus can guide assessment and treatment decisions.METHODS:An expert task force iteratively developed consensus using the Delphi method. Initial survey items were based on systematic review of the literature. Subsequent surveys included new, re-worded or re-rated items.RESULTS:Out of 2175 papers assessing psychomo…
Tartrate-Resistant Acid Phosphatase 5b: A Novel Serum Marker of Bone Resorption
2000
Human serum contains two forms of tartrate-resistant acid phosphatase (TRAP), 5a and 5b. Of these, 5a contains sialic acid and 5b does not. We show here that antigenic properties and pH optimum of TRAP purified from human osteoclasts are identical to those of serum TRAP 5b and completely different from those of serum TRAP 5a, suggesting that 5b would be derived from osteoclasts and 5a from some other source. We developed a novel immunoassay specific for 5b using a monoclonal antibody O1A as capture antibody. O1A did not bind acid phosphatase derived from platelets and erythrocytes. Western analysis showed that O1A was specific for TRAP in both human bone and serum. We measured bound TRAP ac…
Effect of β-cryptoxanthin plus phytosterols on cardiovascular risk and bone turnover markers in post-menopausal women: a randomized crossover trial.
2014
Abstract Background and aim Post-menopausal women are at higher risk of cardiovascular disease and bone demineralization. Phytosterols (PS) may be used for hypercholesterolemia in some groups and β-cryptoxanthin (β-Cx) displays a unique anabolic effect on bone. Our aim was to assess the changes in cardiovascular and bone turnover markers from the oral intake of β-Cx and PS in post-menopausal women. Methods and results A randomized, double-blind, crossover study with β-Cx (0.75 mg/day) and PS (1.5 g/day), single and combined, was performed in 38 postmenopausal women. Diet was supplemented with 1 × 250 mL milk-based fruit drink/day for 4 weeks with a wash-out period of 4-weeks in between. Ser…
Mesencephalic ependymal cysts: treatment under pure endoscopic or endoscope–assisted keyhole conditions
2008
Object Primary intracranial ependymal cysts are extremely rare. Similar to congenital intraparenchymal cysts in the mesencephalon they usually occur with symptoms of an occlusive hydrocephalus or symptoms like Parinaud syndrome, dizziness, or gait disturbance. The objective of this study was to evaluate the surgical methods for the treatment of these cysts and the clinical outcome of the patients. Methods The authors present the clinical records of 8 patients who were treated in their department for symptomatic mesencephalic ependymal cysts in the past 10 years. The patient age ranged from 22 to 60 years with a mean age of 44 years. In 4 cases the authors performed a suboccipital infratent…
Study on the Influence of Beginner Gymnasts’ Neuromuscular Control Using Computer-assisted Move 1 Du Portable Appliance
2014
Abstract The study aims at evaluating, training and improving upper limb neuromuscular control in preschool gymnasts as well as at highlighting the benefits of using computerized resources (MOVE 1 DU portable appliance) in training this control type. The research method chosen for this project consists in conducting an experiment on a group of 10 subjects aged 6-7 years. The key purpose of this study is to offer a more accurate and realistic view on the potential use of computer resources in training the neuromuscular control of the upper limb.
