Search for an excess of events with an identical flavour lepton pair and significant missing transverse momentum in root s=7 TeV proton-proton collis…
2011
Results are presented of a search for supersymmetric particles decaying into final states with significant missing transverse momentum and exactly two identical flavour leptons (e or mu) of opposite charge in sqrt{s}=7 TeV collisions at the Large Hadron Collider. This channel is particularly sensitive to supersymmetric particle cascade decays producing flavour correlated lepton pairs. Flavour uncorrelated backgrounds are subtracted using a sample of opposite flavour lepton pair events. Observation of an excess beyond Standard Model expectations following this subtraction procedure would offer one of the best routes to measuring the masses of supersymmetric particles. In a data sample corres…
Search for diphoton events with large missing transverse momentum in 7 TeV proton-proton collision data with the ATLAS detector
2012
A search for diphoton events with large missing transverse momentum has been performed using proton–proton collision data at √s = 7 TeV recorded with the ATLAS detector, corresponding to an integrated luminosity of 4.8 fb[superscript −1]. No excess of events was observed above the Standard Model prediction and model-dependent 95% confidence level exclusion limits are set. In the context of a generalised model of gauge-mediated supersymmetry breaking with a bino-like lightest neutralino of mass above 50 GeV, gluinos (squarks) below 1.07 TeV (0.87 TeV) are excluded, while a breaking scale Λ below 196 TeV is excluded for a minimal model of gauge-mediated supersymmetry breaking. For a specific …
Use of asthma medication during pregnancy and risk of specific congenital anomalies: A European case-malformed control study.
2015
Background: Pregnant women with asthma need to take medication during pregnancy.Objective: We sought to identify whether there is an increased risk of specific congenital anomalies after exposure to antiasthma medication in the first trimester of pregnancy.Methods: We performed a population-based case-malformed control study testing signals identified in a literature review. Odds ratios (ORs) of exposure to the main groups of asthma medication were calculated for each of the 10 signal anomalies compared with registrations with nonchromosomal, nonsignal anomalies as control registrations. In addition, exploratory analyses were done for each nonsignal anomaly. The data set included 76,249 reg…
Congenital Pediatric Diseases
2008
Major congenital malformations are diagnosed in 4%–6% of all infants and fetuses (Lynberg and Edmonds 1992). About one third of them are the leading cause for infant mortality or morbidity (Grandjean et al. 1999). Malformations of the internal urogenital system are diagnosed in about 1% of all infants and account for approximately 20% of all congenital malformations, thus being one of the three most frequent birth defects (Table 11.1.1). Therefore a pre- and/or postnatally performed ultrasound screening for malformations of the internal urogenital system should be part of the routine to reduce perinatal mortality and morbidity. The reliability and value of ultrasonographic screening for con…
Antenatal Ultrasound Diagnosis of Congenital Malformations of the Urinary Tract: Results and Criticism
1986
From October 1979 to June 1983 220 malformations were diagnosed antenatally at our hospital; 55 (25%) were malformations of the urinary tract, 21 of them hydronephroses and 34 of them dysplasias.
Management of multiple pregnancy with an affected twin
2015
Newborns from multiple pregnancies demonstrate a higher perinatal morbidity and mortality compared to singletons. Prematurity is more frequent in twins and therefore birth weight is significantly lower compared to singletons [1]. Thus, twins are more exposed to prema- turity related diseases (respiratory, cardiovascular, infec- tious, etc.) and to long-term complications [2]. It is very difficult to estimate the increased risk of neonatal mor- bidity related to twinning independently to the increased risk of prematurity. Prematurity is the main reason for most neonatal diseases in twins, but other variables may play a role. Fetal growth restriction [3] and congenital malformationsare major …
Prevalence of hypospadias in Italy according to severity, gestational age and birthweight: an epidemiological study
2009
Abstract Background Hypospadias is a congenital displacement of the urethral meatus in male newborns, being either an isolated defect at birth or a sign of sexual development disorders. The aim of this study was to assess the prevalence rate of hypospadias in different Districts of Italy, in order to make a comparison with other countries all over the world. Methods We reviewed all the newborns file records (years 2001–2004) in 15 Italian Hospitals. Results We found an overall hypospadias prevalence rate of 3.066 ± 0.99 per 1000 live births (82.48% mild hypospadias, 17.52% moderate-severe). In newborns Small for Gestational Age (birthweight th percentile) of any gestational age the prevalen…
Congenital Malformations and Syndromes: Early Diagnosis and Prognosis
2012
Congenital malformations are defects of the morphogenesis of organs or body regions identified during intrauterine development or at birth. They may be isolated and single, or multiple. Their global birth prevalence is about 2–3%. Congenital defects may be caused by genetic and/or environmental factors, acting singly or in combination. Diagnostic and therapeutic tools have allowed better identification of congenital malformations and have reduced long-term morbidity and mortality in affected patients. Because of increased life expectancy, congenital malformations today represent a major issue in health care because of the resources needed for multidisciplinary care.
Historia natural de 30 casos de cavernomas: un seguimiento de dos décadas en el Estado de Paraíba, Brasil
2019
Introducción: Los cavernomas son malformaciones vasculares de bajo flujo que ocurren principalmente en el cerebro y, menos frecuentemente, en la médula espinal. Son lesiones raras y representan alrededor del 5-13% de las malformaciones vasculares del sistema nervioso central. Objetivos: Evaluar el seguimiento de 30 casos de pacientes diagnosticados con cavernomas y describir los hallazgos clínicos, epidemiológicos, topográficos, evolutivos y la conducta terapéutica en un período de 22 años. Metodología: Se trata de un estudio observacional, transversal, de carácter cuantitativo, que incluye pacientes diagnosticados con cavernomas, a través de la recolección de datos en los Servicios de Neur…
Influence of Ad Congruence and Social Cues on the Probability of Choosing a Restaurant
2020
Abstract. Information processing of digital content includes conscious and un-conscious processes, memory, attitudes, and emotions and moods. Build up into the Heuristic‐Systematic Model, that states that persuasion can occur through a systematic or heuristic way, this research explores the effect of social media (SM) ratings and the ad content embedded in the SM website. Online ratings (part of the user-generated content (UGC) in SM platforms) are often heuristics cues. Subtle forms of congruence, such as the matching category between a restaurant advertiser and the third-party ad, as well as UGC, could have an impact on con-sumers’ attitudes towards the former. However, research on …
