An Integration Gateway for Sensing Devices in Smart Environments
Smart Environments, and in particular Smart Homes, have recently attracted the attention of many
researchers and industrial vendors. The proliferation of low-power sensing devices requires
integration gateways hiding the complexity of heterogeneous technologies. We propose a ZigBee
integration gateway to access and integrate low-power ZigBee devices
EvAAL: Evaluating AAL Systems through Competitive Benchmarking
Owing to the complexity of Ambient Assisted Living (AAL) systems and platforms, the evaluation of AAL solutions is a complex task that will challenge researchers for years to come. However, the analysis and comparison of proposed solutions is paramount to enable us to assess research results in this area. We have thus organized an international contest called EvAAL: Evaluating AAL Systems through Competitive Benchmarking. Its aims are to raise interest within the research and developer communities in the multidisciplinary research fields enabling AAL, and to create benchmarks for the evaluation and comparison of AAL systems
Development of an Augmented Reality system applied to a 3D model of the prostate, in order to facilitate the dissection of the tumor and the preservation of the neuro-vascular bundles during robotic-assisted radical prostatectomy.
La realtà aumentata (AR) è una nuova tecnologia adottata in chirurgia prostatica con l'obiettivo di migliorare la conservazione dei fasci neurovascolari (NVB) ed evitare i margini chirurgici positivi (PSM). Abbiamo arruolato prospetticamente pazienti con diagnosi di cancro alla prostata (PCa) sul base di biopsia di fusione mirata con mpMRI positiva. Prima dell'intervento, i pazienti arruolati sono stati indirizzati a sottoporsi a ricostruzione del modello virtuale 3D basato su mpMRI preoperatoria
immagini. Infine, il chirurgo ha eseguito la RARP con l'ausilio del modello 3D proiettato in AR all'interno della console robotica (RARP guidata AR-3D).
I pazienti sottoposti a AR RARP sono stati confrontati con quelli sottoposti a "RARP standard" nello stesso periodo.
Nel complesso, i tassi di PSM erano comparabili
tra i due gruppi; I PSM a livello della lesione indice erano significativamente più bassi nei pazienti riferiti al gruppo AR-3D (5%) rispetto a quelli nel gruppo di controllo (20%; p = 0,01). La nuova tecnica di guida AR-3D per l'analisi IFS può consentono di ridurre i PSM a livello della lesione dell'indiceAugmented reality (AR) is a novel technology adopted in prostatic surgery with the aim to improve the preservation of neurovascular bundles (NVBs) and avoid Positive surgical margins (PSM).We prospectively enrolled patients with a diagnosis of prostate cancer (PCa) on the basis of positive mpMRI-targeted fusion biopsy.Prior to the intervention, patients enrolled were addressed to undergo 3D virtual model reconstruction based on preoperative mpMRI
images. Finally, the surgeon performed RARP with the help of the 3D model projected in AR inside the robotic console (AR-3D guided RARP).
Patients who underwent AR RARP were compared to those who underwent "standard RARP" in the same period.
Overall, PSM rates were comparable
between the two groups; PSMs at the level of the index lesion were significantly lower in patients referred to AR-3D group (5%) than those in the control group (20%; p = 0.01).The novel technique of AR-3D guidance for IFS analysis may allow for reducing PSMs at the level of the index lesion
Ataxia with oculomotor apraxia type 2: a clinical, pathologic, and genetic study
BACKGROUND: Ataxia with oculomotor apraxia type 2 (AOA2) is characterized by
onset between age 10 and 22 years, cerebellar atrophy, peripheral neuropathy,
oculomotor apraxia (OMA), and elevated serum alpha-fetoprotein (AFP) levels.
Recessive mutations in SETX have been described in AOA2 patients.
OBJECTIVE: To describe the clinical features of AOA2 and to identify the SETX
mutations in 10 patients from four Italian families.
METHODS: The patients underwent clinical examination, routine laboratory tests,
nerve conduction studies, sural nerve biopsy, and brain MRI. All were screened
for SETX mutations.
RESULTS: All the patients had cerebellar features, including limb and truncal
ataxia, and slurred speech. OMA was observed in two patients, extrapyramidal
symptoms in two, and mental impairment in three. High serum AFP levels, motor and
sensory axonal neuropathy, and marked cerebellar atrophy on MRI were detected in
all the patients who underwent these examinations. Sural nerve biopsy revealed a
severe depletion of large myelinated fibers in one patient, and both large and
small myelinated fibers in another. Postmortem findings are also reported in one
of the patients. Four different homozygous SETX mutations were found (a
large-scale deletion, a missense change, a single-base deletion, and a
splice-site mutation).
CONCLUSIONS: The clinical phenotype of oculomotor apraxia type 2 is fairly
homogeneous, showing only subtle intrafamilial variability. OMA is an inconstant
finding. The identification of new mutations expands the array of SETX variants,
and the finding of a missense change outside the helicase domain suggests the
existence of at least one more functional region in the N-terminus of senataxin
