Transitional hemodynamics in infants of diabetic mothers by targeted neonatal echocardiography, electrocardiography and peripheral flow study
2017
Objective: Metabolic alterations of intrauterine environment in diabetes mellitus (DM) lead to fetal cardiac dysfunctions that can persist after birth. The aim of the study was to assess the cardiovascular adaptation in infants born to diabetic mothers (IDM) with different degrees of glycometabolic control, in relation to revised guidelines for diagnosis of DM and quality improvements in neonatal care. Materials and methods: An observational case-control study was conducted on IDM with gestational, type 1 and type 2âDM. Relevant maternal and neonatal anamnestic, clinical and laboratory data were analyzed. Electrocardiographic and echocardiographic analyses, including structural and systo-…
Training the Motor Cortex by Observing the Actions of Others During Immobilization
2014
International audience; Limb immobilization and nonuse are well-known causes of corticomotor depression. While physical training can drive the recovery from nonuse-dependent corticomotor effects, it remains unclear if it is possible to gain access to motor cortex in alternative ways, such as through motor imagery (MI) or action observation (AO). Transcranial magnetic stimulation was used to study the excitability of the hand left motor cortex in normal subjects immediately before and after 10 h of right arm immobilization. During immobilization, subjects were requested either to imagine to act with their constrained limb or to observe hand actions performed by other individuals. A third gro…
Early improvement as a predictor of remission and response in schizophrenia: Results from a naturalistic study
2009
AbstractObjectiveTo examine the predictive validity of early improvement in a naturalistic sample of inpatients and to identify the criterion that best defines early improvement.MethodsTwo hundred and forty-seven inpatients who fulfilled ICD-10 criteria for schizophrenia were assessed with the Positive And Negative Syndrome Scale (PANSS) at admission and at biweekly intervals until discharge from hospital. Remission was defined according to the recently proposed consensus criteria, response as a reduction of at least 40% in the PANNS total score from admission to discharge.ResultsReceiver operating characteristic (ROC) analyses showed that early improvement (reduction of the PANSS total sco…
Motor recruitment during action observation: Effect of interindividual differences in action strategy
2020
Abstract Visual processing of other’s actions is supported by sensorimotor brain activations. Access to sensorimotor representations may, in principle, provide the top-down signal required to bias search and selection of critical visual features. For this to happen, it is necessary that a stable one-to-one mapping exists between observed kinematics and underlying motor commands. However, due to the inherent redundancy of the human musculoskeletal system, this is hardly the case for multijoint actions where everyone has his own moving style (individual motor signature—IMS). Here, we investigated the influence of subject’s IMS on subjects’ motor excitability during the observation of an actor…
Enabling resources in people with dementia: a qualitative study about nurses’ strategies that may support a sense of coherence in people with dementia
2015
Aims and objectives To explore nurses’ strategies that may support the sense of coherence in people with dementia. Background People with dementia are often described as people with no resources, people who need support from family or from healthcare personnel to function in everyday life. Despite the disease, some people still have the resources needed to cope well with parts of their lives and experience coherence. To date, no research has explored any nurses’ strategies that may support the sense of coherence in people with dementia. Design The design of the study is qualitative and exploratory. Methods Data were collected by participant observation and focus group interviews. Sixteen re…
The Italian Multiple Sclerosis Database Network (MSDN): The risk of worsening according to IFNβ exposure in multiple sclerosis
2006
We evaluated the risk of worsening according to the length of exposure to interferon beta (IFNβ)ina large cohort of 2090 multiple sclerosis patients collected by the Italian MS Database Network. Overall 44-140 patient-visits with a follow-up of 22-143 patient-years were evaluated. Forty-one per cent of patients were exposed to IFNβ for up to 2 years, 39% for 2- 4 years and 20% for more than 4 years. A Cox regression model was used to analyse two clinical outcomes: disability progression and worsening of relapse rate. The technique of propensity score was applied to reduce bias in the comparison of non-randomized groups. The risks of disability progression (HR=0.23; 95% CI: 0.17 - 0.30) and …
Revisiting mu suppression in autism spectrum disorder
2014
Two aspects of the EEG literature lead us to revisit mu suppression in Autism Spectrum Disorder (ASD). First and despite the fact that the mu rhythm can be functionally segregated in two discrete sub-bands, 8-10 Hz and 10-12/13 Hz, mu-suppression in ASD has been analyzed as a homogeneous phenomenon covering the 8-13 Hz frequency. Second and although alpha-like activity is usually found across the entire scalp, ASD studies of action observation have focused on the central electrodes (C3/C4). The present study was aimed at testing on the whole brain the hypothesis of a functional dissociation of mu and alpha responses to the observation of human actions in ASD according to bandwidths. Electro…
Post-marketing of disease modifying drugs in multiple sclerosis: an exploratory analysis of gender effect in interferon beta treatment.
2009
Background: There are a few and conflicting results from randomised controlled trials (RCTs) pertaining to the influence of gender in response to currently used disease modifying drugs in Multiple Sclerosis (MS). Observational studies may be especially valuable for answering effectiveness questions in subgroups not studied in RCTs. Objective: To conduct a post-marketing analysis aimed to evaluate the gender effect on Interferon beta (IFN beta) treatment response in a cohort of relapsing (RR) MS patients. Methods: A cohort of 2570 IFN beta-treated RRMS was prospectively followed for Lip to 7 years in 15 Italian MS Centers. Cox proportional hazards regression models were used to assess gender…
What Predicts Outcome, Response, and Drop-out in CBT of Depressive Adults? A Naturalistic Study
2012
Background: The efficacy of CBT for unipolar depressive disorders is well established, yet not all patients improve or tolerate treatment. Aims: To identify factors associated with symptomatic outcome, response, and drop-out in depressive patients under naturalistic CBT. Method: 193 patients with major depression or dysthymia were tested. Sociodemographic and clinical variables were entered as predictors in hierarchical regression analyses. Results: A higher degree of pretreatment depression, early improvement, and completion of therapy were identified as predictors for symptomatic change and response. Drop-out was predicted by concurrent personality disorder, less positive outcome expectan…
