    Abstract Crowding is the inability to recognize an object in clutter, usually considered a fundamental low-level bottleneck to object recognition. Here we advance and test an alternative idea, that crowding, like predictive phenomena such as serial dependence, results from optimizing strategies that exploit redundancies in natural scenes. This notion leads to several testable predictions: crowding should be greatest for unreliable targets and reliable flankers; crowding-induced biases should be maximal when target and flankers have similar orientations, falling off for differences around 20°; flanker interference should be associated with higher precision in orientation judgements, leading to lower overall error rate; effects should be maximal when the orientation of the target is near that of the average of the flankers, rather than to that of individual flankers. Each of these predictions were supported, and could be simulated with ideal-observer models that maximize performance. The results suggest that while crowding can affect object recognition, it may be better understood not as a processing bottleneck, but as a consequence of efficient exploitation of the spatial redundancies of the natural world.

    Abstract Psycho-biological resilience is considered one of the most important factors in the epigenetics of aging. Cell senescence exhibits a series of possible biochemical derangements concerning mitochondria, proteasome, genome and membranes. Research has shown that resilience can be acquired through hormesis, a set of conservative and adaptive processes based on biphasic doseresponse to specific mild stressors, such as fasting, intake of polyphenols, exercising, physical and chemical stress and mental engagement. These stimuli were shown to elicit beneficial cellular metabolic pathways, such as sirtuin activation, mechanistic target of rapamycin and insulin growth factor- 1 downregulation, nuclear related factor 2 upregulation and autophagy. The complex of these resilience-building processes plays a documented role in longevity. Mitochondria are regarded as one of the core actors of aging processes and represent the main target of hormetic approaches [mitohormesis]; furthermore, the influence of the mind on mitochondria, and thus on the balance of health and disease has been recently established, leading to the so-called mitochondria psychobiology. Hence, psychologic and physical stress that reflects on these organelles may be regarded as a relevant factor in cell senescence, and thus the proposed "mitoresilience" denomination may be pertinent within the biomedical science of aging. Finally, the quantification of individual resilience is becoming increasingly important in aging science, and the investigation of the autonomic nervous system through heart rate variability (HRV) proved to be a valid method to quantify this parameter. In conclusion, an integrated approach targeting hormetic pathways to improve psychophysical resilience (namely mitoresilience), supported by the monitoring of HRV, may represent a valuable option in longevity medicine.

    Abstract An extended-reality (XR) platform for real-time monitoring of patients' health during surgical procedures is proposed. The proposed system provides real-time access to a comprehensive set of patients' information, which are made promptly available to the surgical team in the operating room (OR). In particular, the XR platform supports the medical staff by automatically acquiring the patient's vitals from the operating room instrumentation and displaying them in real-time directly on an XR headset. Furthermore, information regarding the patient clinical record is also shown upon request. Finally, the XR-based monitoring platform also allows displaying in XR the video stream coming directly from the endoscope. The innovative aspect of the proposed XR-based monitoring platform lies in the comprehensiveness of the available information, in its modularity and flexibility (in terms of adaption to different sources of data), ease of use, and most importantly, in a reliable communication, which are critical requirements for the healthcare field. To validate the proposed system, experimental tests were conducted using instrumentation typically available in the operating room (i.e., a respiratory ventilator, a patient monitor for intensive care, and an endoscope). The overall results showed (i) an accuracy of the data communication greater than 99 %, along with (ii) an average time response below ms, and (iii) satisfying feedback from the SUS questionnaires filled out by the physicians after intensive use.

    Abstract A systematic review on machine-learning strategies for improving generalizability (cross-subjects and cross-sessions) electroencephalography (EEG) based in emotion classification was realized. In this context, the non-stationarity of EEG signals is a critical issue and can lead to the Dataset Shift problem. Several architectures and methods have been proposed to address this issue, mainly based on transfer learning methods. 418 papers were retrieved from the Scopus, IEEE Xplore and PubMed databases through a search query focusing on modern machine learning techniques for generalization in EEG-based emotion assessment. Among these papers, 75 were found eligible based on their relevance to the problem. Studies lacking a specific cross-subject and cross-session validation strategy and making use of other biosignals as support were excluded. On the basis of the selected papers' analysis, a taxonomy of the studies employing Machine Learning (ML) methods was proposed, together with a brief discussion on the different ML approaches involved. The studies with the best results in terms of average classification accuracy were identified, supporting that transfer learning methods seem to perform better than other approaches. A discussion is proposed on the impact of (i) the emotion theoretical models and (ii) psychological screening of the experimental sample on the classifier performances.

    Abstract Purpose: Consensus exits about the clinical benefits of an early referral to multidisciplinary Heart Failure Unit-HFU for old frail patients with HF. Nevertheless, few data are present regarding the prognosis and the predictors of outcome in oldest-old patients managed in this clinical setting. The aim of present study is to identify predictors of 1-year all-cause mortality in very old patients enrolled in our multidisciplinary HFU after an episode of acute decompensated HF.
    Methods: This study is a retro-prospective, single-center cohort analysis of patients managed in our multidisciplinary HFU. Inclusion criterion was diagnosis of HF according to ESC guidelines and age ≥ 85 years, while no exclusion criteria were pre-defined. Baseline clinical and comprehensive geriatric evaluations were recorded during the first visit and follow-up visits were repeated according to our standardized timetable protocol. Primary end-point was 1-year all-cause mortality.
    Results: We enrolled 75 patients aged 89.2 ± 2.8 years; 39 (52.0%) were females. During 1-year follow-up, seventeen patients (22.7%) died. Residual congestion with higher level (> 4) of EVEREST score (HR 1.24: 95% CI 1.04-1.47) and living alone (HR 3.34: 95% CI 1.16-9.64) resulted the two independent predictors of 1-year all-cause mortality at the multivariate Cox regression model. Finally, patients living alone and with an EVEREST score > 4 experienced a worse prognosis as clearly described by a steeper descendent Kaplan-Meier curve.
    Conclusion: In a very old population of patients after an acute decompensated HF, residual congestion and social isolation as living alone identify those with high risk of 1-year death.

    Abstract Early identification of different categories of the risk of scarring in children with first (or follow up) urinary tract infection and/or early detection and treatment of vesicoureteral reflux are important to prevent kidney impairment. The demonstration and grading of reflux is crucial in examination and follow up of any child with urinary tract infection. Nephro-urologic radionuclide studies are able to detect vesicoureteral reflux and reflux nephropathy, such as radionuclide cystography--RNC--(both direct radionuclide voiding cystography--DRVC--and indirect radionuclide cystography-IRC), renal DMSA scintigraphy, MAG3 renal diuresis scintigraphy and DTPA renal diuresis scintigraphy. They allow to assess renal parenchyma integrity, to detect pyelonephritic scars, to evaluate the different aspects of urinary tract function and to measure absolute and relative function after intravenous injection of radiopharmaceuticals. The procedure, image acquisition and processing and the diagnostic relevance of all aforesaid nephro-urologic radionuclide studies are illustrated.

    Abstract The Chapman psychosis-proneness scales-also known as Wisconsin schizotypy scales (WSS)-are among the most used tools to measure schizotypy. The factor structure of the short-form WSS was investigated in a mixed sample of patients with chronic mental disorders and of healthy subjects from the general population. One hundred patients with a chronic mental disorder were enrolled over a 6-month period. For each patient, two controls of same sex and similar age (±5 years) were enrolled; 131 accepted to take part in the study. The unidimensional, the correlated four-factor, the second-order two-factor models, and the bifactor model with two or four orthogonally independent factors of the short-form WSS were tested with confirmatory factor analysis. Good reliability of the short-form WSS was confirmed, as its capacity of differentiating people with and without schizotypy. The bifactor models were superior to other models. However, in both bifactor models the explained common variance (ECV) attributable to the general factor and the percentage of uncontaminated correlations (PUC) were too low to use a general summary score as a measure of a single latent schizotypy variable. Symptoms scores derived from the short-form WSS can be better appreciated within a multidimensional model of schizotypy.

    Abstract This atlas fills a gap in the literature by documenting in detail the role of nuclear medicine imaging of infection and inflammation. The pathophysiologic and molecular mechanisms on which radionuclide imaging of infection/inflammation is based are clearly explained, but the prime focus of the book is on the clinical relevance of such procedures. Their impact is demonstrated by a collection of richly illustrated teaching cases that describe the most commonly observed scintigraphic patterns, as well as anatomic variants and technical pitfalls. Due attention is paid to the application of recently developed techniques, including multimodality fusion imaging such as SPECT/CT and PET/CT. Emphasis is placed in particular on the ability of multimodality imaging to increase both the sensitivity and the specificity of radionuclide imaging. This atlas will be an excellent learning tool for residents in nuclear medicine and illuminating for other specialists with an interest in the field. Learning tool especially useful for residents in nuclear medicine and for specialists in nuclear medicine approaching the field. Useful integration for residents and for specialists also in infectious and autoimmune diseases, as well as in orthopedics
