Evaluation of a rapid antigen detection test (Panbio™ COVID‐19 Ag Rapid Test Device) as a point‐of‐care diagnostic tool for COVID‐19 in a pediatric e…
2021
Abstract We evaluated the Panbio™ COVID‐19 Ag Rapid Test Device as a point‐of‐care diagnostic tool for COVID‐19 in 357 patients at a pediatric emergency department. Thirty‐four patients tested positive by reverse transcription polymerase chain reaction, of which 24 were positive by the antigen assay. The sensitivity and specificity of the assay were 70.5% and 100%, respectively.
Total plasma protein in very preterm babies: prognostic value and comparison with illness severity scores
2013
International audience; OBJECTIVE: We aimed to investigate the predictive value for severe adverse outcome of plasma protein measurements on day one of life in very preterm infants and to compare total plasma protein levels with the validated illness severity scores CRIB, CRIB-II, SNAP-II and SNAPPE-II, regarding their predictive ability for severe adverse outcome. METHODS: We analyzed a cohort of infants born at 24-31 weeks gestation, admitted to the tertiary intensive care unit of a university hospital over 10.5 years. The outcome measure was "severe adverse outcome" defined as death before discharge or severe neurological injury on cranial ultrasound. The adjusted odd ratio (aOR) and 95%…
How Epidemiology of Polycythemia Vera Has Changed in the Last 10 Years: Results From the Whole Prospective Cohort of Patients in Cyto-PV Trial As Com…
2012
Abstract Abstract 1748 Introduction: Polycythemia vera (PV) is a chronic myeloproliferative neoplasms characterized by erythrocytosis, vasomotor disturbances, pruritus, risk of disease progression into acute myeloid leukemia or myelofibrosis and cardiovascular events, the last representing the main cause of morbidity and mortality. Since 2005 the V617F point mutation in Janus Kinase 2 (JAK2) gene gained a dominant role in determining the molecular basis and the diagnosis of PV. We compared the clinical epidemiology of the 1638 patients included in the ECLAP trial in the years 1997 to 2001, with that of a “modern” cohort of 365 PV, JAK2-positive patients included in the Italian CYTO-PV rando…
Usefulness of complementary test in the study of patients with chronic abdominal pain.
2021
Introduction: Chronic abdominal pain (CAP) in children is a symptom that frequently leads to a visit to the paediatrician, which affects family life and occasionally requires the need to perform diagnostic studies (DS). The objective was to carry out a qualitative, quantitative, and economic analysis on the tests requested. Material and methods: An observational, prospective and multicentre study was conducted that included children between 4–15 years old affected by CAP. The difference between organic and functional disorders was taken into account. The following variables were collected: history, warning signs and symptoms, DS, and the cost of these. Results: The study included 235 childr…
LMA Supreme™ and Ambu® AuraGain™ in anesthetized adult patients: a prospective observational study
2017
BACKGROUND Second-generation laryngeal masks with gastric access are increasingly used in daily practice and expand the indications for laryngeal masks in the OR. Only limited data exist comparing different types of laryngeal masks. We investigated the second-generation laryngeal masks LMA Supreme™ and Ambu® AuraGain™ in a clinical setting. We hypothesized that the two devices would be comparable in terms of success rate and airway complications. METHODS After approval from the local ethics committee, data were collected in a prospective trial. Endpoints were success rate, time to insertion and airway morbidity. Anesthesiologists used either the Supreme (Teleflex Medical GmbH) or Gain (Ambu…
Epidemiology of hepatic encephalopathy in german hospitals – the EpHE study
2017
Abstract Background Hepatic encephalopathy (HE) is a serious complication of liver cirrhosis. The proportion of patients with liver cirrhosis attending German hospitals suffering from HE is unknown. Methods In the first part of the study, data of 14 community hospitals and 5 university hospitals covering the years 2010 and 2011 were analyzed retrospectively for the DRG codes of liver cirrhosis and hepatic encephalopathy. In the second prospective part of the multicenter observational study, all patients with liver cirrhosis attending the departments of gastroenterology of 16 participating community hospitals within a study period of 3 months were included and screened for HE clinically acco…
Acetaminophen Use During Pregnancy: Effects on Risk for Congenital Abnormalities
2008
Udgivelsesdato: 2008-Feb OBJECTIVE: We evaluated if acetaminophen, one of the most frequently used drugs among pregnant women is associated with an increased prevalence of congenital abnormalities. STUDY DESIGN: We selected 88,142 pregnant women and their liveborn singletons from the Danish National Birth Cohort who had information on acetaminophen use during the first trimester of pregnancy. We used the National Hospital Registry to identify 3784 (4.3%) children from the cohort diagnosed with 5847 congenital abnormalities. RESULTS: Children exposed to acetaminophen during the first trimester of pregnancy (n = 26,424) did not have an increased prevalence of congenital abnormalities (hazard …
Levetiracetam in Neonatal Seizures as First-line Treatment: A Prospective Study
2017
Aim of the Study: The aim of this study is to evaluate the efficacy and safety of levetiracetam (LEV) as first-line treatment of neonatal seizures. Materials and Methods: This study was conducted in patients of Neonatal Intensive Care Unit of Santo Bambino Hospital, University of Catania, Italy, from January to August 2016. A total of 16 neonates with convulsions not associated with major syndromes, which required anticonvulsant therapy, were included and underwent IV LEV at standard doses. Results: All patients responded to treatment, with a variety range of seizure resolution period (from 24 h to 15 days; mean hours: 96 ± 110.95). No patient required a second anticonvulsant therapy. Regar…
Anaemia during pregnancy as a risk factor for infant iron deficiency: report from the Valencia Infant Anaemia Cohort (VIAC) study.
1990
A prospective cohort study with a 1-year follow-up of 156 neonates was carried out specifically designed to test the hypothesis that there is a positive relationship between iron deficiency during pregnancy and the development of the same disease in newborn infants. Exposure was defined as being born of a mother with ferropenic anaemia at delivery, and cases as the infants who developed iron deficiency during their first year of life. A statistically significant positive association was detected with an odds ratio of 6.57 (95% confidence limits 1.81-25.97). A stratified analysis was also performed to control the effect of potential confounders such as socio-economic variables, feeding pract…
Air Pollution Exposure During Pregnancy and Symptoms of Attention Deficit and Hyperactivity Disorder in Children in Europe
2018
Background: Exposure to air pollution during pregnancy may increase attention-deficit/hyperactivity disorder (ADHD) symptoms in children, but findings have been inconsistent. We aimed to study this association in a collaborative study of eight European population-based birth/child cohorts, including 29,127 mother-child pairs. Methods: Air pollution concentrations (nitrogen dioxide [NO2] and particulate matter [PM]) were estimated at the birth address by land-use regression models based on monitoring campaigns performed between 2008 and 2011. We extrapolated concentrations back in time to exact pregnancy periods. Teachers or parents assessed ADHD symptoms at 3-10 years of age. We classified …
