Microwave Devices for Wearable Sensors and IoT.

The Internet of Things (IoT) paradigm is currently highly demanded in multiple scenarios and in particular plays an important role in solving medical-related challenges. RF and microwave technologies, coupled with wireless energy transfer, are interesting candidates because of their inherent contactless spectrometric capabilities and for the wireless transmission of sensing data. This article reviews some recent achievements in the field of wearable sensors, highlighting the benefits that these solutions introduce in operative contexts, such as indoor localization and microwave sensing.

RF-Powered Low-Energy Sensor Nodes for Predictive Maintenance in Electromagnetically Harsh Industrial Environments.

This work describes the design, implementation, and validation of a wireless sensor network for predictive maintenance and remote monitoring in metal-rich, electromagnetically harsh environments. Energy is provided wirelessly at 2.45 GHz employing a system of three co-located active antennas designed with a conformal shape such that it can power, on-demand, sensor nodes located in non-line-of-sight (NLOS) and difficult-to-reach positions.

HABITAT: An IoT Solution for Independent Elderly.

In this work, a flexible and extensive digital platform for Smart Homes is presented, exploiting the most advanced technologies of the Internet of Things, such as Radio Frequency Identification, wearable electronics, Wireless Sensor Networks, and Artificial Intelligence. Thus, the main novelty of the paper is the system-level description of the platform flexibility allowing the interoperability of different smart devices. This research was developed within the framework of the operative project HABITAT (Home Assistance Based on the Internet of Things for the Autonomy of Everybody), aiming at developing smart devices to support elderly people both in their own houses and in retirement homes, and embedding them in everyday life objects, thus reducing the expenses for healthcare due to the lower need for personal assistance, and providing a better life quality to the elderly users.

Influence of Type of Fixation and Other Characteristics on Outcome after Endovascular Repair of Ruptured Abdominal Aortic Aneurysms.

Background: Endovascular treatment nowadays represents a valuable option in the treatment of ruptured abdominal aortic aneurysms (rAAAs). The aim of this study is to evaluate a 15-year, single-center experience with endovascular treatment of rAAAs and the role of the type of fixation in outcome.

Methods: Retrospective analysis of all consecutive hemodynamically stable and unstable patients with a diagnosed rAAA treated at this hospital with an endovascular procedure between December 1999 and January 2015 was conducted.

OPTICAL COHERENCE TOMOGRAPHY AND INFRARED IMAGES OF ASTROCYTIC HAMARTOMAS NOT REVEALED BY FUNDUSCOPY IN TUBEROUS SCLEROSIS COMPLEX.

Purpose: To detect, describe, and classify the morphologic characteristics of astrocytic hamartomas in tuberous sclerosis complex, using both spectral-domain optical coherence tomography (OCT) and infrared images.

Methods: Ten subjects (20 eyes) with tuberous sclerosis complex underwent a complete ophthalmologic examination and multimodality imaging with spectral-domain OCT and infrared images. The imaging protocol included a 30°scan angle of the posterior pole and of the four quadrants.

Can biological components predict short-term evolution in Autism Spectrum Disorders? A proof-of-concept study.

Background: The clinical and pathogenetic heterogeneity of Autism Spectrum Disorders (ASD) limits our ability to predict its short- and long-term evolution. Aim of this naturalistic study was to observe the clinical evolution of very young children with ASD for 12 months after first diagnosis, in order to identify those children who might develop a more positive trajectory and understand how a wide range of biological, clinical and familial factors can influence prognosis.

Methods: Ninety-two children were characterized in terms of family history, prenatal and perinatal variables, and clinical conditions.

Agomelatine Improves Apathy in Frontotemporal Dementia.

Background/aims: Apathy is the most common initial symptom of frontotemporal dementia (FTD) and has been linked to frontal-subcortical dopaminergic system dysfunction. No pharmacological therapy has been approved for the treatment of apathy, but, on the basis of its physiopathological mechanism, we suspected that increasing prefrontal dopaminergic innervation could improve this disabling symptom.

Methods: We evaluated a group of 24 nondepressed patients with a diagnosis of the behavioral variant of FTD, in order to determine the effectiveness on apathy of agomelatine, an antidepressant with MT1 and MT2 receptor agonism and 5-HT2C receptor antagonism; the latter leads to an increase in prefrontal dopaminergic and noradrenergic tone.

Reduction in retinal nerve fiber layer thickness in tuberous sclerosis complex.

Purpose: The aim of our study was to non-invasively investigate central nervous system axonal integrity in patients with tuberous sclerosis complex (TSC). Diffuse microstructural white matter abnormalities reflecting axonal disorganization, reduced/altered myelination, or gliosis have been described in individuals with TSC. Optical coherence tomography (OCT) is a fast, easy-to-perform, non-invasive, and cost-efficient method to assess retinal morphology in vivo and to measure the thickness of the retinal nerve fiber layer (RNFL).

Are caesarean sections, induced labor and oxytocin regulation linked to Autism Spectrum Disorders?

The etiology of Autism Spectrum Disorders (ASDs) continues to be elusive. While ASDs have been shown to be heritable, several environmental co-factors, such as, e.g.

Effectiveness of community-based treatment on clinical outcome in children with autism spectrum disorders: An Italian prospective study.

Objective: Little is known about outcomes of Autism Spectrum Disorders (ASDs) interventions in real-life settings. The main aim of this naturalistic study was to collect real-life data on the actual ASDs treatment practices in Italy.

Methods: A cohort of 48 children undergoing community-based interventions was observed in terms of personal and environmental characteristics, treatment typology and outcomes.

Reduction in retinal nerve fiber layer thickness in young adults with autism spectrum disorders.

Recent years have seen an increase in the use of retinal nerve fiber layer (RNFL) evaluation as an easy-to-use, reproducible, proxy-measure of brain structural abnormalities. Here, we evaluated RNFL thickness in a group of subjects with high functioning autism (HFA) or with Asperger Syndrome (AS) to its potential as a tool to study autism pathophysiology. All subjects underwent high-resolution spectral domain optical coherence tomography to evaluate RNFL thickness.

Isolated theory of mind deficits and risk for frontotemporal dementia: a longitudinal pilot study.

Objective: Recent data suggest that theory of mind (ToM) deficits represent an early symptom of the behavioural variant of frontotemporal dementia (bvFTD). However, longitudinal data on the natural history of subjects presenting with isolated ToM deficits are lacking. The aim of the study was to verify if isolated ToM deficits represent an at-risk state for prefrontal dysfunction and bvFTD.

Long-term cognitive and behavioral therapies, combined with augmentative communication, are related to uncinate fasciculus integrity in autism.

Recent evidence points to white-matter abnormalities as a key factor in autism physiopathology. Using Diffusion Tensor Imaging, we studied white-matter structural properties in a convenience sample of twenty-two subjects with low-functioning autism exposed to long-term augmentative and alternative communication, combined with sessions of cognitive and behavioral therapy. Uncinate fasciculus structural properties correlated significantly with therapy length and early onset, as well as to clinical outcome, independently from IQ, age or symptoms severity at therapy onset.
