    Abstract Background: Sparing the Great Saphenous Vein capital for possible arterial substitution and recurrence decrease may be an alternative to current ablation options for Varicose Veins treatment. Conservative surgery of varicose veins (CHIVA) was suggested in 1988 by Franceschi, by limited veins interruptions in strategic points. However, the method did not diffuse due to the need for high Duplex expertise to determine the procedure in every single patient.
    Method: Evaluation of the literature regarding saphenous sparing, with special reference to CHIVA.
    Result: It has been realized that basic Ultrasound expertise is sufficient for performing GSV conservation. Most of the time, only a few parameters are needed: a junction competence assessment and a re-entry perforator position.
    Conclusion: For achieving the goal of saphenous conservative treatment, a limited phlebectomy and possible Junction interruption (crossotomy) may be a simplified solution.

    Abstract Embedded systems are nowadays employed in a wide range of application, and their capability to implement calculation-intensive algorithms is growing quickly and constantly. This result is obtained by the exploitation of powerful embedded processors that are often connected to coprocessors optimized for a particular application. This work presents an open-source coprocessor dedicated to the real-time generation of a synthetic signal that mimics the echoes produced by a moving fluid when investigated by ultrasounds. The coprocessor is implemented in a Field Programmable Gate Array (FPGA) device and integrated in an embedded system. The system can replace the complex and inaccurate flow-rigs employed in laboratorial tests of Doppler ultrasound systems and methods. This paper details the coprocessor and its standard interfaces, and shows how it can be integrated in the wider architecture of an embedded system. Experiments showed its capability to emulate a fluid flowing in a pipe when investigated by an echographic Doppler system.

    Title translation Atrial fibrillation and dementia: not everything is clear….
    Abstract The prevalence of dementia is ever increasing, as well as the prevalence of atrial fibrillation (AF). Several studies and systematic reviews evaluated the association between AF and dementia, highlighting an increased risk for dementia (with odds ratios from 1.4 to 1.6), with robust results in patients with previous stroke. In fact, not only vascular dementia, but also Alzheimer's disease seems more frequent in patients with AF, even though the very high heterogeneity of the results does not allow for solid conclusions. One of the mechanisms by which AF can cause dementia is the presence of silent embolic cerebral infarctions, and therefore treatment with oral anticoagulants could reduce the incidence of dementia. The results of several studies and systematic reviews show that this therapy, particularly with the new oral anticoagulants, is associated with a reduction of approximately one third of dementia. Rhythm control, obtained either with pharmacological therapy or catheter ablation, is associated with a reduction of dementia impact as well. The association between AF and cognitive deficit is therefore well documented, being more evident in patients with previous stroke but also present in cohorts of patients without prior vascular events. The development of dementia in AF patients can be due to cerebral infarctions, both clinically evident or silent, as well as by microembolism, microbleeds and hypoperfusion. Oral anticoagulation, particularly with the use of new oral anticoagulants, as well as a rhythm control strategy can reduce the incidence of dementia. More recently, it has been shown that atrial cardiomyopathy is significantly associated with the incidence of dementia, also in patients with no history of AF or stroke.

    Abstract Oral tactile sensitivity underpins food texture perception, but few studies have investigated mechanoreception in oral tissues. During food consumption, oral tissues are exposed to a wide range of temperatures and chemical entities. The objective of the present study was to assess the influence of thermal sensations on lingual roughness sensitivity. Just-noticeable difference thresholds (JNDs) were determined using the staircase method for surface roughness from stainless steel coupons (Ra; 0.177-0.465 µm). Thresholds were assessed when cooling or heating the metal stimuli (n = 32 subjects). Compared to the JND threshold obtained at an ambient stimulus temperature (21 °C: 0.055 ± 0.010 μm), a cold (8 °C) temperature significantly (P = 0.019) reduced tongue sensitivity (i.e. increased JND) to surface roughness (0.109 ± 0.016 μm, respectively) whereas warm and hot temperatures had no significant effect (35 °C: 0.084 ± 0.012 μm; 45 °C: 0.081 ± 0.011 μm). To assess whether the effect of cooling on roughness thresholds is TRPM8-dependent, we collected roughness thresholds in a second cohort of subjects (n = 27) following the lingual application of the cooling compound Evercool 190 (24.3 µM). Interestingly, when Evercool 190 was used to elicit the cold sensation, lingual roughness JNDs were unaffected compared to the control application of water (EC: 0.112 ± 0.016 μm; water: 0.102 ± 0.017 μm; P = 0.604). That lingual roughness sensitivity is decreased by cold temperature, but not chemicals evoking cold sensations, suggests the mechanism underpinning thermal modulation is not TRPM8 dependent.

    Abstract To reach the energy efficiency and the computing capability of biological neural networks, novel hardware systems and paradigms are required where the information needs to be processed in both spatial and temporal domains. Resistive switching memory (RRAM) devices appear as key enablers for the implementation of large-scale neuromorphic computing systems with high energy efficiency and extended scalability. Demonstrating a full set of spatiotemporal primitives with RRAM-based circuits remains an open challenge. By taking inspiration from the neurobiological processes in the human auditory systems, we develop neuromorphic circuits for memristive tonotopic mapping via volatile RRAM devices. Based on a generalized stochastic device-level approach, we demonstrate the main features of signal processing of cochlea, namely logarithmic integration and tonotopic mapping of signals. We also show that our tonotopic classification is suitable for speech recognition. These results support memristive devices for physical processing of temporal signals, thus paving the way for energy efficient, high density neuromorphic systems.

    Abstract Recently, human bocavirus (HBoV) has appeared as an emerging pathogen, with an increasing number of cases reported worldwide. HBoV is mainly associated with upper and lower respiratory tract infections in adults and children. However, its role as a respiratory pathogen is still not fully understood. It has been reported both as a co-infectious agent (predominantly with respiratory syncytial virus, rhinovirus, parainfluenza viruses, and adenovirus), and as an isolated viral pathogen during respiratory tract infections. It has also been found in asymptomatic subjects. The authors review the available literature on the epidemiology of HBoV, the underlying risk factors associated with infection, the virus's transmission, and its pathogenicity as a single pathogen and in co-infections, as well as the current hypothesis about the host's immune response. An update on different HBoV detection methods is provided, including the use of quantitative single or multiplex molecular methods (screening panels) on nasopharyngeal swabs or respiratory secretions, tissue biopsies, serum tests, and metagenomic next-generations sequencing in serum and respiratory secretions. The clinical features of infection, mainly regarding the respiratory tract but also, though rarely, the gastrointestinal one, are extensively described. Furthermore, a specific focus is dedicated to severe HBoV infections requiring hospitalization, oxygen therapy, and/or intensive care in the pediatric age; rare fatal cases have also been reported. Data on tissue viral persistence, reactivation, and reinfection are evaluated. A comparison of the clinical characteristics of single infection and viral or bacterial co-infections with high or low HBoV rates is carried out to establish the real burden of HBoV disease in the pediatric population.

    Abstract Background: With a rapidly growing population of older adults in the U.S., nurses are needed to provide quality gerontological nursing care. However, few nursing students plan to specialize in gerontological nursing and many relate their lack of interest in gerontological nursing to negative pre-existing attitudes toward older adults.
    Purpose: An integrative review was conducted to examine factors associated with positive attitudes toward older adults in baccalaureate nursing students.
    Methods: A systematic database search was performed to identify eligible articles published between January 2012 and February 2022. Data were extracted, displayed in matrix format, and synthesized into themes.
    Results: Two overarching themes were identified as having a positive impact on students' attitudes toward older adults: past rewarding experiences with older adults and gerontology-focused teaching strategies, particularly service-learning projects and simulation.
    Conclusion: Nurse educators can improve students' attitudes toward older adults by incorporating service-learning and simulation activities into nursing curriculum.

    Abstract Introduction: Serogroups A, B, C, W, X, and Y of Neisseria meningitidis are responsible for almost all cases of invasive meningococcal disease. In Italy, vaccination against serogroup B is recommended at 3-13 months, C at 13-15 months, and A, C, Y and W in adolescents (12-18 years). Four quadrivalent meningococcal conjugate vaccines are available. This review describes the available data on a quadrivalent meningococcal tetanus toxoid-conjugate vaccine (MenACYW-TT; MenQuadfi®; Sanofi).
    Areas covered: We identified articles on quadrivalent meningococcal conjugate vaccines indexed on PubMed since 2000. Of the 524 studies identified, 10 human studies investigating the immunogenicity and safety of MenACYW-TT in toddlers, children aged 2-9 years, and individuals 10-55 or ≥56 years are described in detail.
    Expert opinion: In Italy, pediatric and public health groups recommend amending the current vaccination schedule to include a booster dose between 6 and 9 years and quadrivalent vaccine in young adults (≥19 years), targeting waning protection after childhood vaccination and the age cohort with the highest carrier prevalence (adolescents and young adults). MenACYW-TT is a suitable meningococcal vaccine for current and pending recommendations based on high seroprotection rates and a low incidence of adverse events in these age groups. Moreover, it does not require reconstitution.
