The relevance of the religious dimension in the education to universal citizenship (Giorgia Pinelli, Michele Caputo, Maria Teresa Moscato – Università di Bologna) This essay highlights the potential role of the religious dimension in the positively utopian hypothesis of an education to universal citizenship as a fundamental pedagogical target. Starting from some specific philosophical and theoretical studies (Fowler, 2000, 2017; Moscato, Gatti, Caputo, 2012), we carried out several exploratory surveys (Caputo, 2012; Caputo, Pinelli, 2014), and we also acquired some empirical data during some interreligious formative seminars (Draghetti, Pinelli, 2019). We also carried out a national research by survey in Italy, involving a significative sample of 2.675 religious people, which provided many data about the representations and experiences connected to the religious dimension (Moscato, Caputo, Gabbiadini, Pinelli, Porcarelli, 2017). When we speak about the “religious dimension”, it is necessary to distinguish some elements in it. First of all, religiosity: an interactive and dynamic connection between an institutional, historical religion and the psychological and spiritual dynamisms linked to it. Religiosity has a subjective, concrete dimension, composed by psychological, anthropological and philosophical elements. Secondly, the religious sense, which we hypothesize to be the transculturally characterized generative element of the religious experience. Both of the above mentioned elements have to be differentiated from religion, which is an institutional symbolic system characterized by a proper theological and philosophical apparatus, a specific rituality and an organized structure. The interreligious dialogue does not happen among religions, but first of all among people’s religious experiences (Draghetti, Pinelli, 2019). The scientific and social disqualification of religion itself (Caputo, 2019) has delegitimized religiosity as well, reducing it to a mere emotive-affective dimension. On the contrary, as we will try to demonstrate, religiosity presents a positive potential also with respect to civil cohabitation, on condition that it is understood and promoted through conscious educative processes. The evolution of the religious conscience toward tolerance can be born only from a religiosity able to understand the human limits in receiving any possible “revelation”, and consequently able to presume that the one God may have been known by different names or perceived tentatively. Under these conditions, we will be able to reduce conflict among human interpretations, even in religious matters.

Background Elevation of right atrial pressure is a typical feature of acute heart failure (AHF), it is transmitted to renal veins leading to persistent kidney congestion. We aimed to evaluate the role of Doppler ultrasound in monitoring kidney congestion during diuretic therapy. Methods 71 patients (26 F - mean age 80.8±8.2 - mean EF 0.40±13.2) admitted for AHF underwent cardiac and renal Echo Doppler examination at day 1–3–5 of Hospital stay. Parameters of arterial and venous flow within cortical right kidney were recorded. Venous Doppler Profile (VDP) was classified as: continuous (C), pulsatile (P), biphasic (B) or monophasic (M) according to the growing degree of derangement. Arterial resistive index (RI) >0.8 was considered elevated. Correlation between renal hemodynamic changes and clinical outcome (Death and cardiovascular (CV) hospitalization) at 60 days was sought. Outcome VDP derangement (M or B) was detected in 57 patients (80.3%) at day 1 and in 36 at day 5 (52.2%, p After 60 days, 13 (18.3%) patients died and 8 (11.3%) had a CV hospitalization. Kaplan Meier analysis found a significant better outcome in those patients whose VDP did improve after diuretic therapy (Log Rank test p Conclusions Most patients admitted with AHF present deranged VDP. Diuretic treatment lead to VDP improvement and to renal RI decrease. In this perspective study, for the first time VDP improvement after endovenous diuretic treatment resulted associated to reduced risk of death and CV Hospitalization. Evaluation of VDP could become a useful tool in monitoring the efficacy of diuretic treatment in AHF. Funding Acknowledgement Type of funding sources: None. Table 1.

BACKGROUND Acute heart failure (AHF) seems to provoke profound derangement of abdominal hemodynamic, which causes symptoms and impacts on renal function. METHODS 27 patients (10 F - age 78 - EF 0.39) admitted for AHF underwent cardiac and abdominal ultrasound at day 1 and 5. Arterial and venous flow within liver, spleen and kidney were recorded. Portal and Splenic Vein flow was described as continuous, pulsatile or reversed, whereas hepatic vein systolic and diastolic ratio was measured. Renal Venous Doppler Profile (VDP) was classified as: continuous, pulsatile, biphasic or monophasic. Arterial Resistive Index (RI) ≥0.7 was considered elevated. OUTCOME At day 1 most patients presented with some degree of deranged VDP and high RI in all examined organs. At day 5, a significant proportion of patients improved their VDP in Liver, Kidney and Spleen, while the percentage of patients with collapsing IVC did not significantly change. On the arterial side, the proportion of patients with high Hepatic RI dropped significantly. CONCLUSIONS Our preliminary data show that most deranged VDP in abdominal organs and Hepatic RI improve after decongestion despite a nonsignificant trend in improvement in IVC profile. RESULTS Classification day 1 day 5 p IVC Collapsing 24% 34% ns Portal Vein Continous 22% 50% Pulsatile 72% 50% Reversed 6% 0%

Background Acute heart failure (AHF) is often accompanied by impairment in renal function. A profound derangement of normal abdominal haemodynamic is always present during this clinical phase. Methods 14 patients (6 F – mean age 80 – mean EF 0.39) admitted for acute heart failure underwent cardiac and renal Echo Doppler examination at day 1-3-5 of Hospital stay. Parameters of arterial and venous flow within cortical right kidney were recorded. Venous Doppler Profile (VDP) was classified as: continuous (C), pulsatile (P), biphasic (B) or monophasic (M) according to the growing degree of derangement. Arterial resistive index (RI) >0.8 was considered elevated. Correlation between renal hemodynamic (and its changes) with biohumoral and echo parameters was sought. Outcome At day 1 VDP was M or B in 8 patients (57%) and in four (50%) of them dropped to C or P at day 5. RI was elevated in 8 patients at day 1 while only in 4 at day 5. VDP and RI were not related to EF or BNP values. One patient died before day 5, no other worsening heart failure episodes occurred. Two patients (14%) developed acute kidney injury but their VDP and RI were normal and did not change. Three patients (21%) did not improve their BNP (decrease >30%) but this was not associated with VDP or RI changes. Elevated derived pulmonary artery systolic pressure (>40 mmHg) was present in 6 out of 8 patients (75%) with M or B VDP and in all 4 patients with both elevated RI and M or B VDP. Venous Pattern Day 1 Day 3 Day 5 Continous 2 8 5 Pulsatile 4 2 4 Biphasic 2 1 2 Monophasic 6 3 2 Arterial RI >0.8 8 6 4 BNP, pg/ml 1060±1180* 372±281* 424±213* Creatinine, mg/dl 1.4±0.6 1.5±0.6 1.3±0.6 Hb, g/dl 12.1±2.3 12.3±3.6 13.2±2.3 *p>0.05. Conclusions This is the first study exploring changes in renal hemodynamic by echo Doppler during AHF. With respect to previous studies among stable patients, our preliminary data shows a higher proportion of deranged renal venous and/or arterial pattern. After diuretic therapy a trend towards improvement in VDP was recorded. No clear association with other clinical and hemodynamic parameters seems evident.

This paper deals with the automatic classification of Drones using a surveillance radar signal. We show that, using state-of-the-art feature-based machine learning techniques, UAV tracks can be automatically distinguished from other object (e.g. bird, airplane, car) tracks. In fact, on a collection of real data, we measure an accuracy higher than 98%. We have also exploited the possibility of using the same features to distinguish the type of the wing of drone, between Fixed Wing and Rotary Wing, reaching an accuracy higher than 93%.

Hintergrund: Evaluierung der klinischen Ergebnisse 3 Monate nach Implantation einer neuen diffraktiven multifokalen Intraokularlinse (MIOL) mit einer reduzierten Nahaddition von + 2,75 dpt. Methoden: Im Rahmen einer prospektiven Studie wurden Patienten nach erfolgreicher Kataraktoperation oder refraktivem Linsenaustausch mit Implantation einer MIOL (Tecnis ZKB00, Abbott Medical Optics, Santa Ana, California, USA) eingeschlossen. Drei Monate postoperativ wurde die Sehscharfe in unterschiedlichen Testentfernungen bewertet. Bei den postoperativen Untersuchungen nach einer bilateralen IOL-Implantation wurde zusatzlich ein Fragebogen zur Evaluierung der subjektiven Zufriedenheit, der Sehqualitat und der Tragegewohnheiten einer Brille vorgelegt und in die Auswertung mit einbezogen. Ergebnisse: Es wurde zwischen Oktober 2013 und August 2014 bei 115 Augen von 62 Patienten die ZKB00-IOL implantiert. Die postoperative Refraktion lag im spharischen Aquivalent bei − 0,27 ± 0,44 dpt. Der korrigierte binokulare Fernvisus lag bei − 0,01 ± 0,3 logMAR. Der unkorrigierte binokulare Fernvisus wurde mit 0,06 ± 0,08 logMAR nach 3 Monaten ermittelt. Im Nahbereich konnte die unkorrigierte binokulare Sehscharfe mit 0,07 ± 0,10 logMAR nach 3 Monaten postoperativ bestimmt werden. Schlussfolgerung: Die ZKB00-IOL gehort einer neuen Generation von MIOL an, die einen deutlich verbesserten Intermediarvisus anbieten. Unsere Studie belegte fur die Implantation dieser IOL eine ausgezeichnete Sehfunktion in allen Bereichen in Korrelation mit einer sehr hohen allgemeinen Patientenzufriedenheit und einer subjektiv hohen Abbildungsqualitat.

Coastline detection in synthetic aperture radar (SAR) images is crucial in many application fields, from coastal erosion monitoring to navigation, from damage assessment to security planning for port facilities. The backscattering difference between land and sea is not always documented in SAR imagery, due to the severe speckle noise, especially in 1-look data with high spatial resolution, high sea state, or complex coastal environments. This paper presents an unsupervised, computationally efficient solution to extract the coastline acquired by only one single-polarization 1-look SAR image. Extensive tests on Spotlight COSMO-SkyMed images of complex coastal environments and objective assessment demonstrate the validity of the proposed procedure which is compared to state-of-the-art methods through visual results and with an objective evaluation of the distance between the detected and the true coastline provided by regional authorities.

Evaluation of the clinical data 3 months after implantation of a new diffractive multifocal intraocular lens (MIOL) with a reduced near add power of + 2.75 D.In a prospective study, patients who underwent cataract surgery or refractive lens exchange with implantation of an MIOL (Tecnis ZKB00, Abbott Medical Optics, Santa Ana, California, USA) were included. Three months postoperative corrected and uncorrected visual acuities at different distances were measured and evaluated. Those patients that underwent bilateral MIOL implantation additionally filled out a questionnaire 3 months postoperatively.Between October 2013 and August 2014, 115 eyes of 62 patients were implanted with the ZKB00 IOL. Mean postoperative refractions were - 0.27 ± 0.44 D for the spherical equivalent, respectively. Mean binocular CDVA was - 0.01 ± 0.3 logMAR with a mean binocular UDVA of 0.06 ± 0.08 logMAR. For near distance in 40 cm, an UNVA of 0.07 ± 0.10 logMAR three months postoperatively was measured.The ZKB00 IOL belongs to a group of novel MIOL with an increased intermediate visual performance. Our study shows good visual acuity at all distances, as well as a high rate of satisfaction and subjectively good image quality.

This study explores the potential of Synthetic Aperture Radar (SAR) to aid Unmanned Aerial Vehicle (UAV) navigation when Inertial Navigation System (INS) measurements are not accurate enough to eliminate drifts from a planned trajectory. This problem can affect medium-altitude long-endurance (MALE) UAV class, which permits heavy and wide payloads (as required by SAR) and flights for thousands of kilometres accumulating large drifts. The basic idea is to infer position and attitude of an aerial platform by inspecting both amplitude and phase of SAR images acquired onboard. For the amplitude-based approach, the system navigation corrections are obtained by matching the actual coordinates of ground landmarks with those automatically extracted from the SAR image. When the use of SAR amplitude is unfeasible, the phase content can be exploited through SAR interferometry by using a reference Digital Terrain Model (DTM). A feasibility analysis was carried out to derive system requirements by exploring both radiometric and geometric parameters of the acquisition setting. We showed that MALE UAV, specific commercial navigation sensors and SAR systems, typical landmark position accuracy and classes, and available DTMs lead to estimated UAV coordinates with errors bounded within ±12 m, thus making feasible the proposed SAR-based backup system.

Correct identification of obstacles at the periphery of airports is an important issue to ensure safe takeoff, flight, and landing to aircrafts. This work is carried on as part of the obstacle risk assessment and risk mitigation operations in the aviation security framework. This paper presents a novel fully automatic remote sensing methodology for the detection, shape and signature extraction and classification of obstacles to air navigation from very high resolution (VHR) multispectral (MS) satellite stereo couples images, here defined feature extraction (FE). In order to reduce the costs, the proposed technique is applied only on detailed areas where orographic/topographic changes potentially associated with variations in the obstacles to air navigation in wide areas have been previously detected through a low-cost pre-screening change detection (CD) methodology applied to cheaper high resolution (HR) satellite imagery. The combination of CD and FE strategies offers a low-cost and fast solution to the problem of updating airport obstacle chart.

Postural control, osteoporosis, proprioception, exercise training - Abstract
Osteoporosis (OP) is a skeleton systemic disease characterized by a reduced bone mass and deterioration of micro-architecture. OP is often accompanied by an increased risk of fall and consequently a high risk of fracture. Since postural control and proprioception are two of the most significant factors in falls and injury prevention, exercise training, including specific balance and proprioceptive exercises, could be the keys to reducing the risk of fall and fractures. This study was aimed at assessing proprioception and postural control, using Delos Postural Proprioceptive System (DPPS; Delos, Turin, Italy), in persons with osteoporosis, before and after an exercise training.

musculoskeletal diseases ,Osteoporosis, Physical activity - Abstract
INTRODUCTION: Osteoporosis (OP) is characterized by a reduced bone mass, that is accompanied by an increased risk of fracture with consequent pain, decreased physical, social, and functional capacity. Therefore, the impaired postural alignment and the reduced mobility and flexibility of the spine limit the use of the normal motor strategies, important features to reduce the risk of falling. The aim of the study is to evaluate the range of motion (ROM) and joint mobility before and after 22-weeks exercise protocol (ACTLIFE) for women with post-menopausal OP. METHODS: 21 sedentary women (63 ± 5 years) with primary post-menopausal OP were recruited by Center and Metabolic Skeleton Diseases at the Rizzoli Institute Orthopaedic in Bologna. Subjects with vertebral fracture were included. ACTLIFE protocol, aimed at improving joint mobility, muscle force, balance, motor coordination and endurance, was performed by the subjects twice a week for 22 weeks. The subjects were directly followed by the trainers, every 6 weeks the program was changed. The ROM of knee, hip and shoulder and the mobility of low back by sit and reach test were evaluated before and after the program. RESULTS: After 6 months of intervention, shoulders ROM significantly improved from 40.4±36 cm to 29.7±33 cm (p

Fotografia, Immagine, Comportamento, Relazione, Pedagogia - Abstract
Il saggio affronta il problema di come affrontare, metodologicamente, l'insegnamento della fotografia all'interno di un più articolato progetto di educazione all'arte. La proposta si sviluppa da una ridefinizione del mezzo come pratica di relazione, a partire da una sua specificità fenomenologica che lo differenzia dall'immagine manuale. Mentre infatti quest'ultima può essere concepita e prodotta in assenza del soggetto, la fotografia, sia in versione analogica sia in versione digitale, a ragione dalla sua particolare natura tecnica, necessita di una presenza, di un effettivo rapporto soggetto/oggetto per manifestarsi. Recuperando sinteticamente il contributo portato da alcuni fondamentali artisti del Novecento, si definisce così una proposta didattica basata sulla valorizzazione della relazione soggetto/oggetto nella pratica fotografica, anche in contrapposizione a quelle metodologie, genericamente applicate all'analisi dell'immagine pittorica e da essa esposrtate a quella fotografica, che invece si fondano su anlisi di tipo linguistico-strutturale. Il saggio affronta il tema di un approccio pedagogico alla fotografia, a partire dalla valorizzazione di un suo particolare statuto identitario: quello dell'essere necessariamente (per condizione tecnica di produzione) una pratica di relazione che obbliga il soggetto-autore ad essere di fronte al proprio oggetto. Una condizione profondamente differente da quella dell'immagine manuale-pittorica che invece può essere sviluppata "in assenza", cioè senza relazione diretta tra soggetto e oggetto. Questa particolare condizione ha evidentemente un riflesso sulle pratiche pedagogiche che si possono sviluppare attorno all'immagine fotografica che, a partire da tale identità teorica, potrà essere considerata, non solo nel suo statuto di oggetto materiale indagabile e analizzabile per via linguistica (il cosiddetto linguaggio delle immagini appunto, solitamente considerato sostanzialmente analogo tra immagine manuale-pittorica e immagine fotografica), ma nei riflessi di comportamento, di azione e di performance che possono scaturire da tale particolare condizione produttiva.

Espressione di sé ,Pedagogia dell'espressione artistica ,Educazione alle arti ,Creatività ,Innovazione ,Espressione artistica - Abstract
Il saggio, a partire da una autoriflessione sull’esperienza di insegnamento condotta come docente nelle scuole secondarie, fa emergere un “obbiettivo nascosto” del lavoro educativo nella scuola, quella attenzione all’espressione di sé che può rendere il curriculo scolastico meno asettico ed estraneo all’interesse delle nuove generazioni. Le “pratiche artistiche” sono presenti (perlomeno nella secondaria di primo grado) solo all’interno delle discipline di arti visive e musicali. Talvolta vi entrano come frutto dell’estro di alcuni docenti più o meno personalmente orientati e/o competenti in specifiche aree artistico-espressive. Spesso si tratta di attività “occasionali” e/o attività legate a progetti specifici, per lo più informali, valutate solo parzialmente, e non riconducibili all’area di una professionalità riflessiva e soprattutto condivisa. Ciò produce una mancata consapevolezza del valore degli aspetti espressivi nelle diverse discipline, valore “nascosto” alla percezione degli insegnanti dalla dominante dimensione storica e culturale delle conoscenze disciplinari. La tesi di fondo del saggio sottolinea come, da un lato, le concezioni estetiche dominanti nella cultura occidentale non permettano di percepire la rilevanza pedagogica e formativa dell’espressione artistica come espressione di sé, campo di una creatività soggettiva, trasversale a molte esperienze di crescita nell’arco dell’età evolutiva. Dall’altro lato esistono altri fattori, di ordine pedagogico e didattico, che ostacolano la percezione della necessità di una educazione all’espressività artistica, presenti nei modelli didattici, accreditati e diffusi dalle amministrazioni scolastiche (anche a livello internazionale), fortemente omologanti. I modelli della programmazione sono in genere di tipo procedurale, concentrano l’attenzione sulla dimensione cognitiva (basti pensare che tutto il resto, cioè socialità, affettività, dimensioni etico-politiche e religiose, viene definito, da questi modelli, semplicemente come “non cognitivo”). Il tema dell’espressione artistica è oggi strettamente connesso al tema della creatività, intesa per lo più come una soluzione strategica interna al conflitto/competizione dei processi di innovazione tecnologica ed economica legati alla globalizzazione. Tale visione rappresenta un deciso impoverimento delle caratteristiche e delle potenzialità anche educative della creatività. Perciò è necessario superare un tale riduzionismo per cogliere la “creatività” come dimensione della persona in rapporto alla realtà e al “senso/significato” di sé e del mondo. Il prodotto artistico, l’opera d’arte, si presenta così come frutto di un lavoro e di una “visione” della realtà dell’artista, “visione” che si rende manifesta nell’opera, vero e proprio “simbolo” che consente l’accesso al “reale” proprio attraverso la sua fruizione. Il fine ultimo dell’espressione artistica appare come “qualcosa” che eccede il “prodotto” stesso, al punto che quest’ultimo, l’opera d’arte, si rivela un “mezzo” per giungere ad un “oltre”, qualcosa che l’opera richiama ma che non può “concludere” entro di sé. L’importanza educativa e didattica dell’espressione artistica e della creatività e il suo misconoscimento si può riscontrare drammaticamente proprio nella fase adolescenziale, una fase in cui molto spesso il soggetto sperimenta i propri bisogni espressivi in ambienti distanti dai contesti familiari e scolastici, tanto più quando in essi non ci si sente accolti e compresi. Ma in tali contesti informali entrano prepotentemente in gioco anche le nuove possibilità espressive, per lo più sconosciute al mondo adulto, offerte dai nuovi media e dalle nuove tecnologie, oltre che dai nuovi linguaggi giovanili. Ciò significa anche l’abbandono delle nuove generazioni all’arte “selvaggia”, alla ricerca di ciò che può offrire modalità espressive non codificate dal mondo adulto e/o da un passato incapace di farsi ascoltare, o che, agli occhi dei ragazzi “non ha più nulla da dire”.

Il tema della valenza formativa della religiosità è riemerso nel dibattito internazionale in forza del mutamento socioculturale delle società europee e si lega strettamente con le tematiche interculturali e con il fenomeno della globalizzazione. Riemerso perché, per tutto il Novecento, il tema della religiosità è stato ampiamente inabissato da prospettive ideologiche e scientiste dentro un paradigma evoluzionista e/o riduzionista sostanzialmente negazionista di un qualsiasi riconoscimento positivo alla dimensione religiosa, vista come residuo arcaico nel processo della modernità. Per un altro verso, buona parte del pensiero religioso si è attardato in un arroccamento nostalgico di una forma mitizzata di cristianità e/o in una riduzione ideologica di una ortodossia definita in termini sistematico-deduttivi astratti, spesso disancorati dalla concretezza esistenziale del nostro tempo, un pensiero religioso posto sulla difensiva rispetto ai cambiamenti moderni. Le due polarità maggiori non esauriscono un più ampio ventaglio di posizioni sulle questioni richiamate ma di certo rappresentano gli esiti e i propositi più diffusi. In questo quadro i processi educativi (e in essi la scuola e le altre agenzie educative) hanno rappresentato un luogo simbolico dove si è svolto (e tuttora si svolge) il conflitto delle differenti tensioni che hanno animato (e animano) le diverse visioni antropologiche maturate in Occidente. Paradigmatico in questa direzione è il tema della “laicità” nelle sue diverse accezioni maturate sul piano culturale e politico nei sistemi giuridici contemporanei, in quanto il tema della laicità mette a fuoco il rapporto tra cittadinanza e appartenenza religiosa, definisce lo spazio pubblico dell’esperienza religiosa e la sua qualità, e assieme alle forme di convivenza sociale possibili tra le diverse appartenenze religiose. Nel quadro della società multiculturale la religiosità rappresenta una risorsa nel percorso formativo delle giovani generazioni, come emerge da alcune ricerche recenti in cui abbiamo analizzato narrazioni relative alla formazione dell’identità religiosa (Caputo, Pinelli 2014). Chi cresce si trova in un orizzonte dove sono disponibili risorse simboliche e religiose con le quali fare i conti e dalle quali attingere ciò che corrisponde al bisogno religioso, al bisogno di senso delle nuove generazioni. Il riconoscimento della dimensione intima e personale del rapporto con Dio può aiutare a costruire luoghi di “custodia” della libertà del rapporto uomo - Dio. Ed è questo il contenuto più alto e positivo che possiamo attribuire al termine “laicità” e che può essere la base per incontrarci nelle differenze.

L'influsso del buddhismo, in particolare dello zen, sulle arti giapponesi è stato determinante, a partire dal XII-XII secolo, nel trasformare alcuni percorsi artistici in vere e proprie discipline nel cui alveo l'arte diventa strumento di perfezionamento umano. In tal senso l'articolo discute, sulla scorta dei trattati tardi di Zeami Motokiyo, il percorso di ascesa professionale dell'attore nō in chiave di ascesi spirituale. L'approccio antropologico sotteso allo studio riconnette le questioni di ordine filosofico e religioso alle prassi della scena.

Educazione estetica ,Processo educativo ,Religiosità ,Educazione religiosa ,Senso estetico - Abstract
Il nostro saggio, così come il volume, intende esplorare i nessi tra educazione, esperienza religiosa e dimensione estetico-artistica. L’ipotesi di lavoro che guida la nostra esplorazione ha carattere pienamente pedagogico perché riteniamo che la comprensione del processo educativo in tutta la sua complessità passi necessariamente per la “scoperta” della sua natura contemporaneamente religiosa ed estetica. Il modo in cui pensiamo questi ambiti dell’esperienza umana e le categorie che vi applichiamo risentono della particolare storia culturale dell’Occidente, che ci ha consegnato rappresentazioni così consolidate e diffuse da essere ormai divenute “implicite” e irriflesse. Difatti l’articolato e complesso percorso della modernità, giunto al culmine tra il XVIII e il XIX secolo, appare attraversato dal prevalere di approcci razionalistici, di tipo metafisico o empirico-storico. Da un lato la ragione pensata come intima struttura del mondo; dall’altro la sottolineatura della sua affidabilità limitata, circoscritta ad un orizzonte “chiuso”, applicabile solo a comparti definiti della realtà e dell’esperienza. In entrambe le curvature, comunque, è la ragione a definire il terreno di gioco e le regole del sapere scientifico. Il nuovo metodo viene costruito sull’Io: il punto di partenza non è più l’evidenza di un dato di realtà/di natura che si offre all’interpretazione del soggetto, ma l’evidenza del pensiero rispetto a se stesso. Lo studio mostra il permanere della necessità di mantenere aperta la domanda di significato del reale, come Oggetto che trascende l’Io: come già il senso religioso/religiosità, anche il supposto “senso estetico” si configura come struttura educabile; e che un’educazione estetica non possa prescindere dalla consapevolezza del “potere germinativo” di concetti e parole, preoccupandosi non tanto di stabilire cosa sia bello e cosa non lo sia, ma di lasciare aperta per l’educando la possibilità dell’incontro con l’eccedenza di significato che si lascia scoprire nell’impatto con la bellezza stessa, attraverso l’incontro con gli enti finiti. Dimensione estetica e religiosa si situano allora al cuore del processo educativo in quanto domanda consapevole ed esperienza di un significato presente e contemporaneamente trascendente, senza il quale il viaggio dell’educando non potrebbe compiersi.

- Abstract
Objective: The main endpoint of the study was to evaluate if a daily intake of whey protein-based dietary supplement causes a worse response to levodopa in people with Parkinson's Disease (PWPD)., Background: In PWPD, the competition between large neutral aminoacids and levodopa at intestinal absorption level may interfere with dopaminergic therapy's (DRT) effect; therefore, protein redistribution dietary regimen has been suggested. Many dietary supplementations are available to help people in balancing the protein intake and overcoming muscle mass loss. However, most of the products contain protein and could potentially affect levodopa action in PWPD., Methods: We performed a randomised single blind monocentric study on PWPD admitted in the rehabilitative unit for a 4-week multidisciplined intensive aerobic rehabilitation treatment. All patients received a standard protein redistribution dietary regimen plus a whey protein-based oral formula ( N = 26) or Magnesium ( N = 25) twice daily for 28 days. Neurological assessment and physical evaluation were conducted before (T0) and after (T1) rehabilitative treatment; DRT was recorded T0 and T1 as well. The delta of changes within groups in neurological (UPDRS III) and physical (TUG, 6 MW) evaluation scales was compared between groups., Results: Groups were comparable at baseline in clinical and demographic data; at T1, both groups showed a decrease in UPDRS III, TUG and 6 MWT and no differences between deltas were found. DRT remained stable in both groups., Conclusions: Our results show that whey protein supplementation does not interfere with DRT's efficacy and can be used in PWPD who need a protein supplementation without restrictions in intake hours.

- Abstract
Emery-Dreifuss muscular dystrophy (EDMD) is a rare, inherited human disease. Similar to other neuromuscular dystrophies, EDMD is clinically characterized by muscle atrophy and weakness, multi-joint contractures with spine rigidity, and cardiomyopathy. Over time, muscular weakness can lead to dysphagia and a severe lowering of body mass index (BMI), worsening the prognosis. We present the case of a young male patient affected by EDMD, admitted to the hospital for pneumothorax in a severe state of undernourishment. The patient was treated with total parenteral nutrition (TPN) with Smofkabiven®, supplemented with micronutrients (vitamins and trace elements), and with minimal enteral nutrition through food. Within a year, the patient gained 8.5 kg and kept his body weight stable for the 6 years of the follow-up. In this study, we show that TPN ensures the nutritional requirements of EDMD patients in a safe and well-tolerated manner, allowing a considerable and stable improvement in nutritional status, which has a positive impact on the disease itself and the patients' quality of life., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Valoriani, Pinelli, Gabriele and Menozzi.)

- Abstract
Aims: An increase in right atrial pressure is a common feature of acute decompensated heart failure (ADHF). Such increased pressure leads to persistent kidney congestion. A marker to guide optimal diuretic therapy is missing. We aim to correlate intrarenal Doppler (IRD) ultrasound in ADHF patients with clinical outcomes to assess whether renal haemodynamic parameter changes are useful for monitoring kidney congestion., Methods and Results: Between December 2018 and January 2020, ADHF patients requiring intravenous diuretic therapy for at least 48 h were considered for study selection. An IRD blinded examination was performed on Days 1, 3, and 5, and clinical and laboratory parameters were recorded. Venous Doppler profiles (VDP) were classified as continuous (C), pulsatile (P), biphasic (B), or monophasic (M) according to the congestion degree; B and M profiles were considered deranged. A VDP improvement (VDPimp) was defined as a change of ≥1 pattern degree or maintenance of C or P patterns. An arterial resistive index (RI) > 0.8 was considered elevated. Outcomes of death and rehospitalization were gathered at 60 days. Data were assessed by regression and Kaplan-Meier analyses. All 177 ADHF patients admitted were screened, and 72 were enrolled [27 females-median age 81 (76-87) years-median ejection fraction 40% (30-52)]. The VDP derangement decreased from 79.2% on Day 1 to 51.4% on Day 5 (P < 0.05). The RI elevation decreased from 60.6% on Day 1 to 43.1% on Day 5 (P < 0.05). At Day 5, VDPimp was registered in over half of the patients (59.7%). At Day 5, signs of congestion (dyspnoea/oedema/rales), fluid accumulation (pleural/peritoneal fluid), haematocrit, and brain natriuretic peptide improved (P > 0.05). After 60 days, 12 (16.7%) patients were readmitted and 9 (12.5%) died. The VDPimp was identified as the unique independent factor associated with readmission [Hazard Ratio (HR) 0.22, 95% (confidence interval) CI 0.05-0.94, P = 0.04] and death (HR 0.07, 95% CI 0.01-0.68, P = 0.02), with significantly better outcomes identified in VDPimp patients (log-rank test, P < 0.05)., Conclusion: Decongestion may be associated with improvements in many clinical and instrumental parameters, but only VDPimp was associated with better clinical outcomes. The VDPimp should be incorporated in ad hoc ADHF clinical trials to better define its role in everyday practice., Competing Interests: Conflict of interest: None declared., (© The Author(s) 2023.

- Abstract
Background: Parkinson's disease (PD) patients have lower levels of serum 25-hydroxyvitamin D (25(OH)D) than the general population. Previous studies have suggested a negative association between 25(OH)D and clinical features of PD, but the data are inconsistent., Materials and Methods: We conducted a cross-sectional, observational study. Serum 25(OH)D, disease (Hoehn-Yahr stage [HY]) and clinical symptom (Unified Parkinson Disease Rating Scale [UPDRS]) severity and global cognitive functions (Mini-Mental State Examination [MMSE]) were studied in 500 consecutive PD patients not using vitamin D supplements. Information on sunlight exposure and dietary intakes (using a 66-item food frequency questionnaire) were also collected. A convenient sample of age and sex-matched community healthy controls ( N = 100) was included as a control group., Results: PD patients had lower 25(OH)D serum levels than controls. Deficiency status (<20 ng/mL) was found in 65.6% of patients. 25(OH)D levels were independently correlated to sunlight exposure ( P = .002) and vitamin D intake ( P = .009). In multivariate models, using a Mendelian randomization approach, lower serum 25(OH)D was associated with more severe disease (HY, P = .035), worse clinical symptoms (UPDRS Part-III total score [ P = .006] and dopaminergic [ P = .033] and non-dopaminergic subscores [ P = .001]) and greater global cognitive function impairment ( P = .041). Neither cognitive functions nor clinical features were associated with reduced intake of vitamin D and sunlight exposure., Conclusion: : Serum 25(OH)D was negatively correlated with disease and symptoms severity, as well as with global cognitive functions. Our study adds to the evidence that low 25(OH)D may affect the progression of PD negatively. Intervention studies in this area are required.

- Abstract
With the scaling of lateral dimensions in advanced transistors, an increased gate capacitance is desirable both to retain the control of the gate electrode over the channel and to reduce the operating voltage
1 . This led to a fundamental change in the gate stack in 2008, the incorporation of high-dielectric-constant HfO2 (ref.2 ), which remains the material of choice to date. Here we report HfO2 -ZrO2 superlattice heterostructures as a gate stack, stabilized with mixed ferroelectric-antiferroelectric order, directly integrated onto Si transistors, and scaled down to approximately 20 ångströms, the same gate oxide thickness required for high-performance transistors. The overall equivalent oxide thickness in metal-oxide-semiconductor capacitors is equivalent to an effective SiO2 thickness of approximately 6.5 ångströms. Such a low effective oxide thickness and the resulting large capacitance cannot be achieved in conventional HfO2 -based high-dielectric-constant gate stacks without scavenging the interfacial SiO2 , which has adverse effects on the electron transport and gate leakage current3 . Accordingly, our gate stacks, which do not require such scavenging, provide substantially lower leakage current and no mobility degradation. This work demonstrates that ultrathin ferroic HfO2 -ZrO2 multilayers, stabilized with competing ferroelectric-antiferroelectric order in the two-nanometre-thickness regime, provide a path towards advanced gate oxide stacks in electronic devices beyond conventional HfO2 -based high-dielectric-constant materials., (© 2022.

- Abstract
Background: Weight homeostasis is complex in Parkinson's disease (PD) and body weight changes substantially throughout the course of the disease. We designed a case-control study to (i) investigate whether PD is associated with changes in resting energy expenditure (REE), (ii) to assess how accurately REE could be predicted for individuals with PD utilizing the equations constructed for healthy individuals, and (iii) to eventually construct a new equation. Materials & Methods: Measured REE (mREE) was compared between 122 PD patients and 122 gender and body mass index (BMI)-matched controls. The accuracy of estimated REE by 5 common equations (Harris/Benedict-1919, Roza/Shizgal-1984, Mifflin St. Jeor, WHO/FAO and aggregate formula) was investigated in PD using Bland-Altman analysis and reported as the frequency of accurate predictions (±10%). Concordance correlation coefficients (CCC) were also calculated. Then, we regressed a new REE equation - using gender, age, weight, height and Hoehn-Yahr stage - and validated it in an independent sample ( N = 100). Results: No significant difference in mREE was recorded between the whole PD sample and healthy controls. However, mREE was increased in patients with BMI ≥ 30 kg/m
2 and Hoehn-Yahr stage ≥ 3. Limited accuracy was present in the available REE equations (accurate prediction [±10%] frequency, <60% for all). For the new equation, the proportion of accurate prediction was 67.0% (overestimation, 24.0%) and CCC was 0.77. Conclusion: PD patients are not commonly characterized by an increase in REE. This is limited to patients suffering from obesity and more severe disease. Common REE equations appear to be inaccurate. The new predictive equation proposed in this study provided better REE estimates.- Published

- Abstract
The aim of this study is to validate the Italian version of the Religious Beliefs and Mental Illness Stigma Scale (I-RBMIS): a self-report measure of religious beliefs that may contribute to stigma regarding mental disorders. Scale validation included: linguistic validation; pilot test for understandability; face validity; factor analysis as test of dimensionality; Kaiser-Meyer-Olkin test to evaluate sample sampling adequacy; internal consistency was assessed using Cronbach's alpha; scale validity was assessed through concurrent criterion validity using as gold standard the Italian version of Attribution Questionnaire 27 and mental health knowledge schedule; A total of 311 people agreed to participate in the study. Face validity showed that 13 items out of 16 were completely understandable while only three items (4, 9 and 13) highlighted small lexical concerns. The average compilation time was under 4 min. Bartlett's test for sphericity was statistically significant (Χ
2 = 1497.54; df = 120; p < 0.001). Cronbach's alpha values were acceptable both for the entire questionnaire (0.80) and for the morality/sin subscale (0.73), whereas it was slightly below the standard cutoff for the spiritually oriented causes/treatments (0.68). Scale validity showed a positive correlation between I-RBMIS and AQ-27-I, and a negative correlation between I-RBMIS and MAKS-I. I-RBMIS demonstrated good psychometric properties to assess stigmatizing religious beliefs toward mental illness in general population., (© 2021.

- Abstract
Background: Achieving a reliable venous access in a particular subset of patients and/or in emergency settings can be challenging and time-consuming. Furthermore, many hospitalized patients do not meet the criteria for central venous catheter positioning, unless an upgrade of the treatment is further needed. The mini-midline catheter has already showed to be reliable and safe as a stand-alone device, since it is easily and rapidly inserted and can indwell up to 1 month., Methods: In this further case series, we retrospectively evaluated data from 63 patients where a previously inserted mini-midline catheter was upgraded to a central venous catheter (the devices inserted in the arm replaced by peripherally inserted central catheter and others inserted "off-label" in the internal jugular replaced by single lumen centrally inserted central catheter), being used as introducer for the Seldinger guidewire., Results: The guidewire replacement was been made even early (after 1 day) or late (more than 10 days), usually following a need for an upgrade in treatment. No early or late complications were reported., Conclusion: According to the preliminary data we collected, this converting procedure seems to be feasible and risk-free, since neither infectious nor thrombotic complications were reported.

- Abstract
This study examined the association between dynamic angiopoietin-2 assessment and COVID-19 short- and long-term clinical course. We included consecutive hospitalized patients from 1 February to 31 May 2020 with laboratory-confirmed COVID-19 from 2 Italian tertiary referral centers (derivation cohort, n = 187 patients; validation cohort, n = 62 patients). Serum biomarker levels were measured by sandwich enzyme-linked immunosorbent assay. Lung tissue from 9 patients was stained for angiopoietin-2, Tie2, CD68, and CD34. Cox model was used to identify risk factors for mortality and nonresolving pulmonary condition. Area under the receiver operating characteristic curve (AUROC) was used to assess the accuracy of 3- and 10-day angiopoietin-2 for in-hospital mortality and nonresolving pulmonary condition, respectively. Three-day angiopoietin-2 increase of at least twofold from baseline was significantly associated with in-hospital mortality by multivariate analysis (hazard ratio [HR], 6.69; 95% confidence interval [CI], 1.85-24.19; P = .004) with AUROC = 0.845 (95% CI, 0.725-0.940). Ten-day angiopoietin-2 of at least twofold from baseline was instead significantly associated with nonresolving pulmonary condition by multivariate analysis (HR, 5.33; 95% CI, 1.34-11.77; P ≤ .0001) with AUROC = 0.969 (95% CI, 0.919-1.000). Patients with persistent elevation of 10-day angiopoietin-2 levels showed severe reticular interstitial thickening and fibrous changes on follow-up computed tomography scans. Angiopoietin-2 and Tie2 were diffusely colocalized in small-vessel endothelia and alveolar new vessels and macrophages. Angiopoietin-2 course is strongly associated with COVID-19 in-hospital mortality and nonresolving pulmonary condition. Angiopoietin-2 may be an early and useful predictor of COVID-19 clinical course, and it could be a relevant part of disease pathogenesis. Angiopoietin-2 blockade may be a COVID-19 treatment option., (© 2021 by The American Society of Hematology.)

- Abstract
Objective: We evaluated the efficacy of muscle-targeted nutritional support on the functional outcomes of multidisciplinary intensive rehabilitation treatment (MIRT) in patients with Parkinson disease (PD) or parkinsonism., Methods: We conducted a pragmatic, bicentric, randomized (1:1), assessor-blind controlled trial (Protein, Leucine and Vitamin D Enhancing Rehabilitation [PRO-LEADER]; April 2017 to January 2018) in cognitively intact patients with PD or parkinsonism and undergoing a 30-day MIRT. Patients (n = 150) received a standard hospital diet with or without a whey protein-based nutritional supplement enriched with leucine and vitamin D twice daily. The primary efficacy endpoint was the increase in the distance walked during a 6-minute walking test (6MWT). Secondary endpoints were changes in 4-meter walking speed, Timed Up and Go test (TUG), Berg balance scale, handgrip strength, Self-assessment Parkinson's Disease Disability Scale, body weight, and skeletal muscle mass (SMM)., Results: Nutritional support resulted in greater increase in the distance walked during 6MWT (mean 69.6 meters [95% confidence interval (CI) 60.7-78.6]) than no support (51.8 meters [95% CI 37.0-66.7]): center-adjusted mean difference, 18.1 meters (95% CI 0.9-35.3) ( p = 0.039). Further adjustment for changes in dopaminergic therapy and SMM yielded consistent results: mean difference, 18.0 meters (95% CI 0.7-35.2) ( p = 0.043). A meaningful effect was also found for the following secondary endpoints: 4-meter walking speed ( p = 0.032), TUG ( p = 0.046), SMM, and SMM index ( p = 0.029). Six patients discontinued the nutritional therapy due to mild side effects., Conclusion: The consumption of a whey protein-based nutritional formula enriched with leucine and vitamin D with MIRT improved lower extremity function and preserved muscle mass in patients with PD or parkinsonism.Clinicaltrials.gov IDENTIFIER: NCT03124277., Classification of Evidence: This study provides Class I evidence that for patients with parkinsonism undergoing intensive rehabilitation, a whey protein-based nutritional formula enriched with leucine and vitamin D increased distance walked on the 6MWT., (© 2019 American Academy of Neurology.)

- Abstract
Background: In patients with difficult peripheral venous access, alternative techniques require expertise and are invasive, expensive, and prone to serious adverse events. This brought us to designing a new venous catheter (JLB® Deltamed, Inc.) for the cannulation of medium and large bore veins; it is echogenic, and available in different lengths (60 / 70 / 80 mm) and Gauges (14 / 16 / 17 / 18)., Methods: We led a multi-center observational convenience sampling study to evaluate safety and effectiveness of JLB. Data was collected from June 2015 to February 2018. Inclusion criteria were age ⩾ 18, difficulty in obtaining superficial venous access in the veins of the arm, need for rapid infusion, or patient's preference., Results: We enrolled 1000 patients, mean age 66.8 years. In total, 951 (95.1%) had the device placed in internal jugular vein, 28 in basilic or cephalic vein, 15 in femoral vein, 5 in axillary vein (infra-clavicular tract), and 1 in the external jugular vein. The procedure was performed by attending physicians or emergency medicine residents under US guidance. Mean procedure time (from disinfection to securing) was approximately 240 s. Mean attempts number was 1.21. Early complications (<24 h) occurred in four patients, consisting in two soft tissue hematoma, one phlebitis, and one atrial tachyarrhythmia. No major complications (such as pneumothorax) were reported. Mean indwelling time was 168 h (7 days); early occlusion/dislocation occurred in four cases., Conclusion: According to preliminary data, the application of JLB appears to be safe, cost-effective, and rapid to place bedside.

- Abstract
Background: Although several studies have suggested that abnormalities in gut microbiota may play a critical role in the pathogenesis of PD, data are still extremely heterogeneous., Methods: 16S gene ribosomal RNA sequencing was performed on fecal samples of 350 individuals, subdivided into idiopathic PD (n = 193, of whom 39 were drug naïve) stratified by disease duration, PSP (n = 22), MSA (n = 22), and healthy controls (HC; n = 113). Several confounders were taken into account, including dietary habits., Results: Despite the fact that unadjusted comparison of PD and HC showed several differences in relative taxa abundances, the significant results were greatly reduced after adjusting for confounders. Although most of these differences were associated with disease duration, lower abundance in Lachnospiraceae was the only difference between de novo PD and HC (remaining lower across almost all PD duration strata). Decreased Lachnospiraceae and increased Lactobacillaceae and Christensenellaceae were associated with a worse clinical profile, including higher frequencies of cognitive impairment, gait disturbances, and postural instability. When compared with HC, MSA and PSP patients shared the changes in PD, with a few exceptions: in MSA, Lachnospiraceae were not lower, and Prevotellaceae were reduced; in PSP, Lactobacillaceae were similar, and Streptococcaceae were reduced., Conclusions: Gut microbiota may be an environmental modulator of the pathogenesis of PD and contribute to the interindividual variability of clinical features. Data are influenced by PD duration and several confounders that need to be taken into account in future studies. Prospective studies in de novo PD patients are needed to elucidate the net effect of dysbiosis on the progression of the disease. © 2018 International Parkinson and Movement Disorder Society., (© 2018 International Parkinson and Movement Disorder Society.)

- Abstract
In Zambia, chronic malnutrition still is one of the most common problem among children. To fight against malnutrition, the easiest short-term solution could be to combine specific types of food with affordable local plants. A large variety of natural food resources grow in Zambia, such as Moringa oleifera (MO), whose leaves are known for their health benefits, but are not consumed much by local populations. We analysed Zambian MO powder obtained from dried leaves and found that it contains large amounts of protein, minerals and vitamins, such as iron, calcium and carotenoids. These characteristics make MO a good and sustainable complementary solution to malnutrition. We also evaluated the acceptability and the safety of dietary supplementation with MO powder in malnourished children for 30 days. A daily dose of 14 g daily was safe and well accepted. Its regular use in the menu of local populations may be viable proposition.

- Abstract
Introduction: Our objective is to describe the dietary habits, food preferences and adherence to Mediterranean diet (MeDi) of a large sample of Italian Parkinson's Disease (PD) patients compared to a group of controls., Methods: Dietary habits of 600 PD patients from throughout Italy and 600 controls matched by gender, age, education, physical activity level and geographical residence, were collected using the ON-GP Food Frequency Questionnaire. Then, we compared patients by disease duration and the presence of swallowing disturbances., Results: Overall, adherence of PD patients (males, 53.8%; mean disease duration, 9.2 ± 7.0 years) to MeDi was similar to controls (score, 4.8 ± 1.7 vs. 4.9 ± 1.6; P = 0.294). Patients consumed less alcohol and fish and drank significantly less water, coffee, and milk which resulted also in lower total fluids intake. On the contrary, they ate more fruit, cooked vegetables, cereals and baked items, more dressings and more sweets in general. Disease duration was associated with increased intake of several food groups but it was not associated with changes in MeDi score (P = 0.721). Patients with swallowing disturbances (n = 72) preferred softer and more viscous food but preferences did not result in differences in dietary pattern. However, patients with dysphagia drank less fluids (P = 0.043)., Discussion: PD patients presented different dietary habits and food preferences compared to the general population and adherence to MeDi was not associated with disease duration. Self-reported dysphagia was associated with reduced intake of fluids. These aspects may be amenable to change in order to improve the management of nutritional issues in this patient population., (Copyright © 2017 Elsevier Ltd. All rights reserved.)

- Abstract
Background & Aims: Parkinson's disease (PD) patients can benefit considerably from appropriate nutritional care, particularly from diet. However, there is limited evidence on the eating habits of PD patients and their relationship with the features of the disease., Methods: We conducted a large case-control study. Consecutive PD patients (N = 600) receiving systematic nutritional care and healthy controls (N = 600) matched (1:1) for age, gender, education, physical activity level and residence were studied using a 66-item food frequency questionnaire. The relationship between dietary habits and the following features of PD were investigated in patients: body weight, energy balance, constipation, and levodopa therapy (dose) and its related motor complications., Results: PD patients had lower BMI and reported higher food intake than controls. BMI was found to be inversely associated with disease duration and severity, and levodopa-related motor complications, whereas energy intake was positively associated with these variables. An increase in protein intake by 10 g over physiological requirements (0.8 g/kg/day) corresponded to a mean increase in levodopa dose of 0.7 mg/kg/day. Constipation was also associated with higher levodopa requirements. Finally, protein intake and its distribution throughout the day influenced levodopa-related motor complications., Conclusion: The management of protein intake and the treatment of constipation should be considered to be an integral part of the care of PD patients. Attention should always be focused on energy intake also. This would result in the maintenance of nutritional status, the optimization of levodopa-therapy and the minimization of its related motor complications., (Copyright © 2016 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

- Abstract
Background: Right ventricular (RV) function is difficult to be measured but plays a role in morbility and mortality of patients with cardiopulmonary diseases, so many echocardiographic parameters have been developed from M-mode, B-mode and Doppler tissue imaging (DTI) evaluation. Right ventricular presystolic peak velocity (RVPrP) measured with DTI of the tricuspidal annulus and its changes in RV dysfunction have never been assessed in a patient's cohort of stable patients with cardiovascular risk factors. RVPrP velocity could have a role in RV function evaluation; this study addresses such issue., Methods: Four hundred thirty-six consecutive patients were submitted to a complete echocardiographic examination with the contemporary evaluation of the following RV function indexes: Tricuspid Annulus Plane Systolic Excurtion (TAPSE), RV Systolic Peak (RVSyP) and RVPrP. Pulmonary artery systolic pressure (PASP), left ventricular and RV diastolic function were also evaluated., Results: According to TAPSE and RVSyP taken alone or in combination, 113 patients had RV dysfunction, while 323 patients had normal RV function. RVPrP was reduced in patient's group with RV dysfunction with respect to patient's group with preserved RV function (16.48±7.3 cm/s vs. 23.98±8.4 cm/s, respectively, P<0.001). RVPrP was related with RVSyP (P<0.001) and with TAPSE (P=0.002). TAPSE and RVSyP revealed a poor concordance to define RV dysfunction. PASP was higher in patient's group with reduced RV function (P=0.033)., Conclusions: The study showed RVPrP able to detect stable patients with RV dysfunction.

- Abstract
Objectives: Our objective was to evaluate the efficacy of probiotics and prebiotics in patients with Parkinson disease (PD) and constipation., Methods: We conducted a tertiary setting, randomized, double-blind, placebo-controlled trial in patients with PD with Rome III-confirmed constipation based on 2-week stool diary data at baseline. Patients (n = 120) were randomly assigned (2:1) to either a fermented milk, containing multiple probiotic strains and prebiotic fiber, or placebo, once daily for 4 weeks. The primary efficacy endpoint was the increase in the number of complete bowel movements (CBMs) per week. The key secondary endpoints were 3 or more CBMs and an increase by one or more CBMs per week during weeks 3 and 4., Results: For the primary endpoint, the consumption of a fermented milk containing probiotics and prebiotics resulted in a higher increase in the number of CBMs (mean 1.2, 95% confidence interval [CI] 0.8-1.6) than placebo (0.1, 95% CI -0.4% to 0.6%) (mean difference 1.1, 95% CI 0.4-1.8; p = 0.002). For the key secondary endpoints, a higher number of patients in the probiotics-prebiotics group vs the placebo group reported 3 or more CBMs (p = 0.030; 58.8% vs 37.5%; odds ratio = 2.4, 95% CI 1.1-5.2) and an increase by one or more CBMs (p = 0.004; 53.8% vs 25.0%; odds ratio = 3.5, 95% CI 1.8-8.1) during weeks 3 and 4., Conclusions: The consumption of a fermented milk containing multiple probiotic strains and prebiotic fiber was superior to placebo in improving constipation in patients with PD., Clinicaltrialsgov Identifier: NCT02459717., Classification of Evidence: This study provides Class I evidence that for patients with PD who have constipation, fermented milk containing probiotics and prebiotics increases the frequency of CBMs., (© 2016 American Academy of Neurology.)

- Abstract
Objectives: To estimate prevalence of sarcopenia and dynapenia in outpatients with Parkinson disease (PD) and to investigate their association with the features of the disease., Design: Cross-sectional study., Setting: A specialized tertiary care center., Participants: Consecutive patients (n = 364) aged 65 years or older, affected by parkinsonian syndromes., Measurements: Skeletal muscle mass (SMM), as well as strength and gait speed (GS) were assessed by bioimpedence analysis, handgrip dynamometry, and the 4-meter walking test, respectively. Based on these assessments, sarcopenia was diagnosed using the European Working Group on Sarcopenia in Older People criteria. Dynapenia was defined as handgrip strength less than 30 kg in men and less than 20 kg in women., Results: In total, 235 patients (64.6%) had a diagnosis of idiopathic PD. Low SMM index was recorded in 27 patients. Due to gait disturbances and postural instability, GS could not be measured in 98 patients and was found to be reduced in 61.3% of those assessed. Prevalence of sarcopenia and dynapenia was 6.6% (95% confidence interval [CI] 4.3-9.7) and 75.5% (95% CI 70.8-79.9), respectively. Sarcopenia tended to be higher in patients unable to perform GS assessment and was unrelated to the type of parkinsonian syndrome. It was associated with older age, longer disease duration, more severe disease, and higher disability in activities of daily living, as assessed by disease-specific clinical rating scale. Dynapenia was directly associated with parkinsonism other than PD, older age, and disability, whereas regular physical therapy appeared to be a preventive factor. However, it was unrelated to disease duration and severity. Finally, the disability score of activities of daily living was inversely correlated with handgrip strength and GS, whereas no association was found with SMM index., Conclusion: Being primarily motor disorders, parkinsonian syndromes are characterized by progressive disability in performing activities of daily living. Impaired functional status is a prominent feature of this patient population, independently of disease duration and severity. Sarcopenia is mainly related to advancing disease and, due to a significant sparing of SMM, is an infrequent condition, likely to play a minor role in disability. Several factors could be responsible for this favorable body composition (eg, motor symptoms, levodopa therapy) and deserve further investigation. The prognostic impact of sarcopenia also needs to be addressed., (Copyright © 2016 AMDA – The Society for Post-Acute and Long-Term Care Medicine. Published by Elsevier Inc. All rights reserved.)

- Abstract
Purpose: Evaluation of the clinical data 3 months after implantation of a new diffractive multifocal intraocular lens (MIOL) with a reduced near add power of + 2.75 D., Methods: In a prospective study, patients who underwent cataract surgery or refractive lens exchange with implantation of an MIOL (Tecnis ZKB00, Abbott Medical Optics, Santa Ana, California, USA) were included. Three months postoperative corrected and uncorrected visual acuities at different distances were measured and evaluated. Those patients that underwent bilateral MIOL implantation additionally filled out a questionnaire 3 months postoperatively., Results: Between October 2013 and August 2014, 115 eyes of 62 patients were implanted with the ZKB00 IOL. Mean postoperative refractions were - 0.27 ± 0.44 D for the spherical equivalent, respectively. Mean binocular CDVA was - 0.01 ± 0.3 logMAR with a mean binocular UDVA of 0.06 ± 0.08 logMAR. For near distance in 40 cm, an UNVA of 0.07 ± 0.10 logMAR three months postoperatively was measured., Conclusion: The ZKB00 IOL belongs to a group of novel MIOL with an increased intermediate visual performance. Our study shows good visual acuity at all distances, as well as a high rate of satisfaction and subjectively good image quality., (Georg Thieme Verlag KG Stuttgart · New York.)

- Abstract
Refractory status epilepticus (RSE) is a particular critical condition characterized by seizures that continue despite the use of first- and second-line therapies and by high mortality. To date, only one prospective study investigated clinical features and prognostic factors in RSE. In this study, we performed a one-year prospective survey to identify clinical features, outcomes, and variables associated with the development of RSE in the adolescent and adult population of Modena, northern Italy. We observed 83 episodes of SE in 83 patients. In 31% of the cases, third-line therapy (anesthetic drug) was needed. Among this group, 14% resolved and were classified as RSE, while, in 17%, seizures recurred at withdrawal of anesthetics and were classified as super-RSE. The development of RSE/super-RSE was associated with a stuporous/comatose state at presentation and with the absence of a previous history of epilepsy. Refractory status epilepticus/super-refractory status epilepticus showed a worse outcome compared with responsive SE: 54% versus 21% for 30-day mortality; 19% versus 56% for a return to baseline condition. This prospective study confirms stupor/coma at onset as a relevant clinical factor associated with SE refractoriness. We observed a rate of RSE comparable with previous reports, with high mortality and morbidity. Mortality in the observed RSE was higher than in previous studies; this result is probably related to the low rate of a previous epilepsy history in our population that reflects a high incidence of acute symptomatic etiologies, especially the inclusion of patients with postanoxic SE who have a bad prognosis per se.
