Dépistage échographique anténatal des anomalies mineures de bon pronostic : impact émotionnel, représentations parentales et relation mère-enfant

Abstract: L’echographie fœtale est un outil a present banalise du depistage antenatal. Des anomalies mineures considerees comme de bon pronostic sont reperees chez 5 a 10 % des femmes enceintes, et leur annonce a un impact psychologique substantiel. L’approche psychanalytique met en lumiere la maturation progressive des representations maternelles de l’enfant au cours de la grossesse, ses relations avec les interactions postnatales, et la suspension des investissements lors d’un traumatisme psychique comme l’annonce d’une anomalie fœtale. Les etudes par autoquestionnaires montrent que la revelation de signes mineurs augmente l’anxiete des couples. Le niveau d’angoisse est d’autant plus important que l’information fournie aux futurs parents est floue et qu’il existe une incertitude sur le pronostic de l’anomalie. Les etudes cliniques a partir d’entretiens semistructures et d’observations des interactions montrent une suspension de l’investissement du futur enfant au cours de la grossesse, une modification des representations maternelles et des modifications des interactions precoces mere-enfant. L’anxiete, associee a des symptomes depressifs, et les troubles des interactions peuvent persister jusqu’a deux mois post-partum. Des mesures de prevention sont discutees : formation des professionnels a l’annonce au cours de l’echographie, information des patientes sur les enjeux de l’echographie avant meme la realisation de l’examen, elaboration de consensus sur la valeur diagnostique des signes mineurs pour clarifier l’information, reperage des familles necessitant un accompagnement et des propositions de prise en charge precoce en fin de grossesse et en post-partum precoce.

Clinical outcomes of interactive, intensive and individual (3i) play therapy for children with ASD: a two-year follow-up study

Abstract: The outcomes of psycho-educational interventions for Autism Spectrum Disorders (ASDs) comorbid with severe to moderate intellectual disability (ID) are insufficiently documented. In this prospective study, we examined a developmental individual, interactive and intensive approach, called the ‘3i method’, which is based on play therapy. Twenty DSM-IV-TR ASD subjects (mean chronological age 63.8 ± 37.8 months; mean developmental age 19.5 ± 6.6 months) were included and followed the 3i method for 24 months. Developmental and behavioural skills were assessed at baseline and after 24 months using the VABS, PEP-R and Nadel Imitation scale. Autism severity was evaluated using the Child Autism Rating Scale (CARS) and the Autism Diagnostic Interview (ADI-R). After 2 years of the 3i method, our 3 primary outcome variables significantly increased (VABS developmental age of socialization increased by 83%, age of communication by 34%, and Nadel Imitation score by 53%). Almost all VABS and PEP-R domains significantly improved. Additionally, increases in the VABS socialization score were positively correlated with the total number of treatment hours and CARS score; all ADI-R areas significantly decreased; and diagnoses had changed in 47.5% of the subjects (37% for PDD-NOS and even 10.5% for ID without PDD). Children who followed the 3i method for 2 years had significantly improved behavioural and developmental skills and showed a clear decrease in autism severity. These results suggest that the 3i method may be useful for autistic children by improving their daily interactions with their social environment. was retrospectively registered on May 20th, 2014 by the French Agency for drug and health (ANSM) under number ID-RCB 2014-A00542–45, reference: B148558–31.

Bremsstrahlung from proton bombardment of nuclei

Abstract: Various targets were bombarded with 38 to 185-Mev protons. Photons from these targets were viewed at experimentally available angles from the proton beam with a 180-deg pair spectrometer capable of detection in the photon energy range of 8 to 150 Mev. The accumulated spectra above 20 Mev, after subtraction of some e (as Fe/sup 59 /sup 0/ photon contamination, are assumed to be due to proton bremsstrahlung. The general spectral features are explained in terms of electric- dipole radiation from p-n coilisions, where the target neutrons are in motion. The detailed features are discussed in terms of the available theoretical predictions; there is good agreement with the phenomenological calculation using n-p scattering data. (auth)

Renal Function and Body Mass Index Contribute to Serum Neurofilament Light Chain Levels in Elderly Patients With Atrial Fibrillation

Abstract: Objective Serum neurofilament light chain (sNfL) is increasingly used as a neuroaxonal injury biomarker in the elderly. Besides age, little is known about how other physiological factors like renal function and body mass index (BMI) alter its levels. Here, we investigated the association of estimated glomerular filtration rate (eGFR) and BMI with sNfL in a large sample of elderly patients with atrial fibrillation (AF). Methods This is a cross-sectional analysis from the Swiss-AF Cohort (NCT02105844). We measured sNfL using an ultrasensitive single-molecule array assay. We calculated eGFR using the chronic kidney disease epidemiology collaboration (CKD-EPI) creatinine (eGFRcrea) and creatinine–cystatin C (eGFRcrea–cys) formulas, and BMI from weight and height measurements. We evaluated the role of eGFR and BMI as determinants of sNfL levels using multivariable linear regression and the adjusted R2 (R2adj). Results Among 2,277 Swiss-AF participants (mean age 73.3 years), eGFRcrea showed an inverse curvilinear association with sNfL after adjustment for age and cardiovascular comorbidities. BMI also showed an independent, inverse linear association with sNfL. The R2adj of models with age, eGFRcrea, and BMI alone was 0.26, 0.35, and 0.02, respectively. A model with age and eGFRcrea combined explained 45% of the sNfL variance. Sensitivity analyses (i) further adjusting for vascular brain lesions (N = 1,402 participants with MRI) and (ii) using eGFRcrea–cys yielded consistent results. Interpretation In an elderly AF cohort, both renal function and BMI were associated with sNfL, but only renal function explained a substantial proportion of the sNfL variance. This should be taken into account when using sNfL in elderly patients or patients with cardiovascular disease.

Using Multivariate Statistics

Abstract: Thank you for downloading using multivariate statistics. As you may know, people have look hundreds times for their favorite novels like this using multivariate statistics, but end up in infectious downloads. Rather than reading a good book with a cup of tea in the afternoon, instead they juggled with some harmful bugs inside their laptop. using multivariate statistics is available in our digital library an online access to it is set as public so you can download it instantly. Our books collection saves in multiple locations, allowing you to get the most less latency time to download any of our books like this one. Merely said, the using multivariate statistics is universally compatible with any devices to read.
