Abstract
Abstract Radiomics represents the convergence of artificial intelligence and radiological data analysis, primarily applied in the diagnosis and treatment of cancer. In the head and neck region, squamous cell carcinoma is the most prevalent type of tumor. Recent radiomics research has revealed that specific bio-imaging characteristics correlate with various molecular features of Head and Neck Squamous Cell Carcinoma (HNSCC), particularly Human Papillomavirus (HPV). These tumors typically present a unique phenotype, often affecting younger patients, and show a favorable response to radiation therapy. This study provides a systematic review of the literature, summarizing the application of radiomics in the head and neck region. It offers a comprehensive analysis of radiomics-based studies on HNSCC, evaluating its potential for tumor evaluation, risk stratification, and outcome prediction in head and neck cancer treatment.

Economic evaluation of tele-resuscitation intervention on emergency department pediatric visits in the Niagara Region, Canada a pilot study. FRONTIERS IN HEALTH SERVICES 2023; 3:1105635. [PMID: 37342797 PMCID: PMC10277730 DOI: 10.3389/frhs.2023.1105635] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Accepted: 05/17/2023] [Indexed: 06/23/2023]
Abstract
Introduction The use of telemedicine in critical care is emerging, however, there is a paucity of information surrounding the costs relative to health gains in the pediatric population. This study aimed to estimate the cost-effectiveness of a pediatric tele-resuscitation (Peds-TECH) intervention compared to the usual care in five community hospital emergency departments (EDs). Using a decision tree analysis approach with secondary retrospective data from a 3-year time period, this cost-effectiveness analysis was completed. Methods A mixed methods quasi-experimental design was embedded in the economic evaluation of Peds-TECH intervention. Patients aged <18 years triaged as Canadian Triage and Acuity Scale 1 or 2 at EDs were eligible to receive the intervention. Qualitative interviews were conducted with parents/caregivers to explore the out-of-pocket (OOP) expenses. Patient-level health resource utilization was extracted from Niagara Health databases. The Peds-TECH budget calculated one-time technology and operational costs per patient. Base-case analyses determined the incremental cost per year of life lost (YLL) averted, and additional sensitivity analysis confirmed the robustness of the results. Results Odds ratio for mortality among cases was 0.498 (95% CI: 0.173, 1.43). The average cost of a patient receiving the Peds-TECH intervention was $2,032.73 compared to $317.45 in usual care. In total, 54 patients received the Peds-TECH intervention. Fewer children died in the intervention group resulting in 4.71 YLL. The probabilistic analysis revealed an incremental cost-effectiveness ratio of $64.61 per YLL averted. Conclusion Peds-TECH appears to be a cost-effective intervention for resuscitating infants/children in hospital emergency departments.

Abstract
The first 5 years of life are characterized by incredible growth across domains of child development. Drawing from over 50 years of seminal research, this chapter contextualizes recent advances in language sciences through the lens of developmental cascades to explore complexities and connections in acquisition. Converging evidence-both classic and contemporary-points to the many ways in which advances in one learning system can pose significant and lasting impacts on the advances in other learning systems. This chapter reviews evidence in developmental literature from multiple domains and disciplines (i.e., cognitive, social, motor, bilingual language learning, and communication sciences and disorders) to examine the phenomenon of developmental cascades in language acquisition.

Classification accuracy of the Quick Interactive Language Screener for preschool children with and without developmental language disorder. JOURNAL OF COMMUNICATION DISORDERS 2022; 100:106276. [PMID: 36335826 DOI: 10.1016/j.jcomdis.2022.106276] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Revised: 10/07/2022] [Accepted: 10/25/2022] [Indexed: 06/16/2023]
Abstract
INTRODUCTION This research examined the classification accuracy of the Quick Interactive Language Screener (QUILS) for identifying preschool-aged children (3;0 to 6;9) with developmental language disorder (DLD). We present data from two independent samples that varied in prevalence and diagnostic reference standard. METHODS Study 1 included a clinical sample of children (54 with DLD; 13 without) who completed the QUILS and a standardized assessment of expressive grammar (Syntax subtest from the Diagnostic Evaluation of Language Variation-Norm Referenced; Structured Photographic Expressive Language Test-Preschool 2nd Edition; or Structured Photographic Expressive Language Test-3 rd Edition). Study 2 included a community sample of children (25 with DLD; 101 without) who completed the QUILS and the Auditory Comprehension subtest of the Preschool Language Scales-5th Edition (PLS-5; Zimmerman et al., 2011). Discriminant analyses were conducted to compare classification accuracy (i.e., sensitivity and specificity) using the normreferenced cut score (< 25th percentile) with empirically derived cut scores. RESULTS In Study 1, the QUILS led to low fail rates (i.e., high specificity) in children without impairment and statistically significant group differences as a function of children's clinical status; however, only 65% of children with DLD were accurately identified using the norm-referenced cutoff. In Study 2, 76% of children with DLD were accurately identified at the 25th percentile cutoff and accuracy improved to 84% when an empirically derived cutoff (<32nd percentile) was applied. CONCLUSIONS Findings support the clinical application of the QUILS as a component of the screening process for identifying the presence or absence of DLD in community samples of preschool-aged children.

Abstract
Abstract
Background
Brain tumour patients often have neurocognitive deficits which can result in problems with activities in daily living that are cognitively complex. Currently, no valid and reliable brain tumour-specific instrument to measure these instrumental activities of daily living (IADL) is available, but such an instrument is being developed. This study aimed to validate the EORTC IADL-BN32 questionnaire, comprising five multi-item and two single item scales, in a large set of international brain tumour patients.
Material and Methods
This international study was conducted in 10 countries worldwide. Primary and metastatic brain tumour patients and their proxies were requested to complete the EORTC IADL-BN32 and a subjective cognitive questionnaire (MOS COG-R) at multiple time points. Several psychometric properties were evaluated with baseline data, including the structural validity (bi-factor confirmatory factor analysis [CFA]), reliability (internal consistency), construct validity (known groups comparisons) and patient-proxy congruency (intra-class correlation coefficients [ICC], Spearman's correlation).
Results
At baseline, 326 patients ( 30% low-grade glioma, 37% high-grade glioma (HGG) and 33% brain metastases) and 311 proxies completed the EORTC IADL-BN32. The bi-factor CFA was found to have a satisfactory model fit (CFI=0.92 and TLI=0.90), and other parameters indicated a good fit (RMSEA=0.08 and SRMR=0.05), thereby validating the preliminary scale structure, but also an IADL sum score. The multi-item scales showed good (0.9>α≥0.8) to excellent (α≥0.9) internal consistency (range α=0.86-0.97). Known groups comparisons analyses regarding patient’s cognitive status (indications vs. no cognitive impairment), subjective cognitive complaints (MOS COG-R ≤30 vs. >30), basic ADL (Barthel Index <100 vs. 100) and performance status (KPS <70 vs. ≥70) showed significant differences on all IADL outcome measures in line with a priori defined hypotheses. On a group level, patient and proxy ratings had moderate to strong correlations, however, proxies tended to report more problems on all scales. The ICCs showed moderate to good congruency between patients and proxies (range ICC: 0.63-0.81).
Conclusion
The evaluated psychometric properties support the current scale structure of the EORTC IADL-BN32. Additional psychometric properties with longitudinal data are needed, such as test-retest reliability and responsiveness, to further validate the EORTC-IADL BN32 questionnaire.

Abstract
Introduction Tobacco smoking is one of the leading causes of preventable morbidity and mortality worldwide (WHO, 2020). Smoking cessation campaigns have been effective at reducing smoking in the general population, but not in individuals with mental illness (Lê Cook et al., 2014). A downward trend in smoking has been noted in EU countries but smoking rates have remained stable in Malta (Country Health Profile, 2019). Objectives This audit aims to assess smoking status, provision of smoking cessation advice and psychotropic dose adjustment depending on smoking status by the Bormla Mental Health Team. Methods Patient health records were reviewed for patient demographics, psychiatric diagnosis, medical co-morbidities, smoking status and cessation advice and changes in psychiatric medication according to smoking status. Results Of the 171 patients studied, 35% (n=61) were smokers, 33% (n=58) were non-smokers while in 30% (n=52) the smoking status was undocumented. Smokers had a mean age of 50 years with an almost equal gender distribution (49% (n=30) male and 51% (n=31) female). The most common documented psychiatric diagnoses were depression (52.5% (n=32)) and anxiety (34.5% (n=21)), while 59% (n=36) had documented medical co-morbidities. Only 14% (n=9) where given smoking cessation advice and one patient was referred to the smoking cessation clinic. One third of smokers (n=20) were prescribed psychotropic medications which are affected by smoking status but only two patients had their doses adjusted. Conclusions Improved smoking cessation advice, referral to services, consideration of smoking cessation while prescribing and documentation are need to better patient care. Disclosure No significant relationships.

A Longitudinal Study of Language Use During Early Mother-Child Interactions in Spanish-Speaking Families Experiencing Low Income. JOURNAL OF SPEECH, LANGUAGE, AND HEARING RESEARCH : JSLHR 2022; 65:303-319. [PMID: 34890248 PMCID: PMC9150737 DOI: 10.1044/2021_jslhr-21-00329] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Revised: 08/18/2021] [Accepted: 09/09/2021] [Indexed: 06/13/2023]
Abstract
PURPOSE This longitudinal study assessed continuity and stability of productive language (vocabulary and grammar) and discourse features (turn-taking; asking and responding to questions) during mother-child play. METHOD Parent-child language use in 119 Spanish-speaking, Mexican immigrant mothers and their children at two ages (M = 2.5 and 3.6 years) was evaluated from transcriptions of interactions. RESULTS Child productive language significantly increased over the year, whereas mothers showed commensurate increases in vocabulary diversity but very little change in grammatical complexity. Mother-child discourse was characterized by discontinuity: Mothers decreased their turn length and asked fewer questions while children increased on both measures. Rates of responding to questions remained high for both mothers and children even as children increased and mothers decreased over time. Mothers and children showed significant rank-order stability in productive language and measures of discourse. Mothers' rate of asking questions and children's responses to questions during the first interaction predicted children's receptive vocabulary a year later. CONCLUSIONS As children become more sophisticated communicators, language input remains important, with discourse features growing in relevance. Children's early opportunities to respond to parents' questions in the context of play benefit their language skills. This work extends the evidence base from monolingual English-speaking families and is interpreted in the context of prior research on parenting practices in U.S. families of Mexican origin.

Abstract
Aim In response to the COVID-19 pandemic, all non-urgent surgery was suspended, with orthopaedic surgery among the worst affected. We conducted an infodemiological study to explore changes in internet searches for joint pain at a population level since the start of the pandemic. Method Bayesian structural time-series methods were employed to evaluate the impact of cancelled orthopaedic operations on Google search interest in Knee, Hip and Shoulder pain in the UK. Data were extracted from Google Trends from January 2016-2021. The bsts package was used to construct counterfactual time series, incorporating local linear trend and yearly seasonal components. Causal effects were determined using the CausalImpact package, with 95% CIs and posterior probabilities calculated. 17 March 2020 was used for pre-/post-period cut-off as non-urgent surgery was suspended on this date. P value < 0.05 was significant. R version 4.0.3 was used for analyses. Results Knee pain was the most popular search term, followed by Shoulder pain then Hip pain. The onset of the COVID-19 pandemic was associated with a significant increase in searches for Knee pain (Relative effect [95% CI] = 14% [-0.85%, 29%], p = 0.031). However, there was no significant effect on searches for Hip pain (Relative effect [95% CI] = -1.3% [-15%, 12%], p = 0.427) or Shoulder pain (Relative change [95% CI] = 6.5% [-7.9%, 21%], p = 0.195). Conclusions Our findings suggest a greater impact of COVID-19 on the prevalence of knee pain, compared to hip/shoulder pain. This has implications for planning future orthopaedic surgery delivery and deciding on the priority order for rescheduled operations.

Abstract
Abstract
Aim
The COVID-19 pandemic has had wide-ranging effects on healthcare, society and everyday life. As the public’s health priorities shift, we sought to investigate the resulting impact of COVID-19 on global interest in Ear, Nose and Throat (ENT) surgery.
Method
We used Google Trends to examine worldwide search interest in the following core ENT operations following the onset of the COVID-19 pandemic: Tonsillectomy, Adenoidectomy, Thyroidectomy, Rhinoplasty, Septoplasty, Functional Endoscopic Sinus Surgery, Mastoidectomy, and Tympanoplasty. Bayesian structural time-series models were used to generate counterfactual time series, and relative differences between observed and expected search interest were calculated. Causal effects were subsequently determined, along with 95% CIs and posterior probabilities. R version 4.0.3 was used for analyses.
Results
Search interest in all measured ENT procedures was significantly reduced at the onset of the COVID-19 pandemic. Interest in Rhinoplasty recovered after 8 weeks and continued to rise to a peak of 27% greater than expected, with a cumulative Relative effect of + 11% [95% CI: 3.9%, 20%]. In contrast, significantly reduced search interest was observed for all other procedures analysed (Relative effect, range: -16% to -36%, all p values < 0.05).
Conclusions
Our findings suggest divergent changes in public interest in common ENT procedures. While all other ENT operations investigated were less frequently searched following the pandemic onset, interest in Rhinoplasty at times increased to over 25% greater than expected. This could represent a shift in patient attitudes to disorders of the Ear, Nose and Throat and warrants further investigation at the individual-level.

Abstract
Abstract
BACKGROUND
The final days of life of Brain Tumor patients (BT) present special challenges and often palliative care approach is underutilyzed. Several studies reported that BT patients in the last months of life receive frequent hospital readmissions and ER accesses as result of bad quality of End of Life care. Early integration of pallative care has been demonstrated to improve quality of care in advanced stage of disease and quality of death in cancer patients. With the aim to evaluate pattern of treatment and the rate of hospital readmission in the last months of life, we retrospectively analyzed a consecutive serie of BT patients discharged after a diagnosis of BT.
MATERIAL AND METHODS
Data regarding hospital readmission and treatment received in the last two months of life were collected from the Lazio Region Healthcare database. Adult patients discharged with diagnosis ICD-9 191.* between 1/1/2010 until 31/12/2019, were included in this study.
RESULTS
6672 patients were identified and 3045 who have died before 31/12/2019 were included (median age 67 y;M1700). In the last two month of life 42.6% received hospital reamission (4.6% intensive care unit) and 37.9% had ER accesses. 24.5% received chemotherapy and 12.1% radiotherapy. In the last 30 days 33% were readmitted in hospital and 24.2% were admitted in ER. 11.7% were treated with chemotherapy and 6% with radiotherapy.
CONCLUSION
Strategies to improve quality of care at the end of life and to decrease re-hospitalization and futile treatments are becoming increasingly important to improve quality of death and to reduce costs of Healthcare System.

Abstract
Abstract
BACKGROUND
Involving patients and caregivers is an important component of clinical guideline development. The three main Italian scientific associations for neurology, neuro-oncology and palliative care (SIN-AINO-SICP) recently appointed a joint task force (TF) of clinicians and researchers to develop specific guidance on palliative care of people with primary brain tumours, following the GRADE approach. To identify clinical questions meaningful to the patients and caregivers, a qualitative approach was used.
MATERIAL AND METHODS
Based on the existing literature and on consensus, the TF identified nine intervention areas, whose relevance was apprised by patients (via personal semi-structured interviews) and bereaved caregivers (via focus groups, FGs) from five tertiary neuro-oncology centres. Participants were prompted to provide their personal disease-related experience, and were asked to elicit the areas that mostly impacted their own lives. Interviews and FGMs were audio-recorded, transcribed and analysed using thematic analysis.
RESULTS
Twenty interviews and five FGs (28 caregivers) were completed between late 2020 and early 2021. Preliminary findings show that all the pre-specified areas were defined as important by participants. Most discussed topics were communication, organization and service satisfaction, cognitive and psychological issues, and advance care planning (ACP). Caregivers focused their discussions on the need for patient psychological support, difficulties experienced with symptoms control (e.g. epileptic seizures, behavioural changes), communication and organizational issues.
CONCLUSION
Participation of Italian patients with brain tumours and family caregivers was high and information-rich. All of the nine guideline intervention areas were considered important, communication, care organization, symptom control and ACP being the most discussed.

Abstract
The cultural value of respeto (respect) is central to Latine parenting. Yet, how respeto manifests in the interactions of Latine parents and their young children remains unexamined. Low-income Mexican immigrant Spanish-speaking mothers and their 2.5-year-old toddlers (N = 128) were video-recorded during play (M age = 30.2 months, SD = 0.52), and two culturally informed items of respeto were coded: parent calm authority and child affiliative obedience. Respeto related to standard ratings of mother and child interactions (e.g., maternal sensitivity and child engagement) but also captured unique features of parent-child interactions. Respeto related to mothers' and toddlers' language production and discourse during the interaction, and explained unique variance in language variables above standard ratings of mother-child interaction. This is the first effort to document a culturally salient aspect of dyadic interaction in Mexican immigrant mothers and young children and to show that respeto relates to language use during mother- child interactions.

Abstract
This longitudinal study documents the key role of early joint engagement in the language and early literacy development of Mexican-American children from low-income households. This rapidly growing population often faces challenges as sequential Spanish-English language learners. Videos of 121 mothers and their 2.5-year-old children interacting in Spanish for 15 min were recorded in 2009-2011 in the Dallas-Fort Worth metropolitan area. Researchers reliably rated general dyadic features of joint engagement-symbol-infused joint engagement, shared routines and rituals, and fluency and connectedness-that have been found to facilitate language development in young English-speaking children. The construct respeto, a valued aspect of traditional Latino parenting, was also rated using two culturally specific items-the parent's calm authority and the child's affiliative obedience. In addition, three individual contributions-maternal sensitivity, quality of maternal language input, and quality of child language production-were assessed. General features of joint engagement at 2.5 years predicted expressive and receptive language at 3.6 years and receptive language and early literacy at 7.3 years, accounting for unique variance over and above individual contributions at 2.5 years, with some effects being stronger in girls than boys. The level of culturally specific joint engagement did not alter predictions made by general features of joint engagement. These findings highlight the importance of the quality of early communication for language and literacy success of Mexican-American children from low-income households and demonstrate that culturally specific aspects of early interactions can align well with general features of joint engagement.

Abstract
Background The outbreak of Coronavirus disease 2019 (COVID-19) made imperative the use of protective devices as a source control tool. As there is no definite antiviral treatment and effective vaccine, the only efficient means of protecting and mitigating infectious contagion has been the use of personal protective equipment, especially by healthcare workers. However, masks affect the humidification process of inhaled air, possibly leading to a basal inflammatory state of the upper airways. Study design This is a single-center observational study conducted at the University Hospital of Catania from April 1, 2020, to June 31, 2020. Methods We analyzed the role of protective masks on the elimination of upper airways complaints in healthcare workers of the University Hospital of Catania. We evaluated 277 subjects through a self-administered 17 item questionnaire based on respiratory, work performance and health-related quality of life domains. Results A higher prevalence of nasal and ocular symptoms, perceived reduced work performance, difficulty in concentrating, and sleep disorders were found. After two weeks adhering to a list of good practices that we recommended, significant reversibility of the symptoms investigated and work performance enhancement were observed. Conclusions Despite clinical complaints related to personal protective equipment, effective amelioration through usage rules is easily obtained. Given the essential use of protective masks, healthcare workers have to adhere to appropriate work and safety prevention rules.

Abstract
OBJECTIVE Chronic rhinitis is a common disease with an incidence of 40% in the Western population. Allergic rhinitis (AR) affects half of the adult population, while in children prevalence of AR vs. non-allergic rhinitis (NAR) of 3-4:1 is reported. Nasal cytology is the diagnostic test that has made it possible to clarify the cellular population of the nasal mucosa. The aims of the present study were to define the distribution of chronic rhinopathy in adult and pediatric populations, to classify "cellular" NAR into subgroups based on cytological features, and to identify overlapped rhinitis (OR). PATIENTS AND METHODS A retrospective study was conducted on 907 patients, divided into two groups: 135 children (69 females and 66 males, average age 9.8 years (range 4-17) and 772 adults (392 females and 380 males, average age 45.28 years (range 18-90). All patients with a suspicion of rhinopathy were submitted to nasal endoscopy, Skin Prick test (SPT), dosage of serum specific IgE, CT scan of nasal, and sinusal structures when chronic rhinosinusitis was suspected. RESULTS In the adult population of the study, 61% presented a diagnosis of chronic rhinitis: 213 patients (45.2%) had AR, 31 (6.6%) OR, and 227 (48.2%) NAR (77.5% of these patients presented a pattern of "cellular" NAR). In the pediatric population, 83% patients presented a rhinopathy: 61 (54.5%) with AR, 38 (34%) with NAR, and 13 (11.5%) with OR. Within the NAR group, 71% had a "cellular" pattern. CONCLUSIONS Nasal cytology is a tool that provides a more precise differential diagnosis of chronic rhinitis through the study the of nasal mucosa and the identification of "cellular" NAR and OR, even in the pediatric population.

Abstract
This study investigated the relation between Dual Language Learners' (N = 90) vocabulary and grammar comprehension and word learning processes in preschool (aged 3-through-5 years). Of interest was whether: (a) performance in Spanish correlated with performance in English within each domain; and (b) comprehension predicted novel word learning within and across languages. Dual-language experience was evaluated as a potential moderator. Hierarchical linear modeling revealed stronger predictive associations within each language than across languages. Across languages, results varied by experience and domain. Structural sensitivity theory suggests exposure to two languages heightens awareness of parameters along which languages vary and provides a framework for interpreting complex associations within and across languages. Knowledge from one language may influence learning in both.

Abstract

The
methylation of amide nitrogen atoms can improve the stability,
oral availability, and cell permeability of peptide therapeutics.
Chemical N-methylation of peptides is challenging.
Omphalotin A is a ribosomally synthesized, macrocylic dodecapeptide
with nine backbone N-methylations. The fungal natural
product is derived from the precursor protein, OphMA, harboring both
the core peptide and a SAM-dependent peptide α-N-methyltransferase domain. OphMA forms a homodimer and its α-N-methyltransferase domain installs the methyl groups in trans on the hydrophobic core dodecapeptide and some
additional C-terminal residues of the protomers. These post-translational
backbone N-methylations occur in a processive manner
from the N- to the C-terminus of the peptide substrate. We demonstrate
that OphMA can methylate polar, aromatic, and charged residues when
these are introduced into the core peptide. Some of these amino acids
alter the efficiency and pattern of methylation. Proline, depending
on its sequence context, can act as a tunable stop signal. Crystal
structures of OphMA variants have allowed rationalization of these
observations. Our results hint at the potential to control this fungal α-N-methyltransferase for biotechnological applications.

Vestibular drop attack: A potential origin from perilymphatic fistula? Med Hypotheses 2020; 140:109668.

Abstract
Vestibular drop attacks are defined as a sudden fall to the ground without an obvious loss of consciousness lasting a few minutes or seconds. They are usually associated with Meniere's Disease during Tumarkin's phase. This hypothesis was produced in consideration of the case of a young girl affected by perilymphatic fistula and her Drop attacks. Is possible to consider perilymphatic fistulas a drop attack cause? Drop attack could be related with a vestibular sympathetic reflex alteration because it is involved in blood pressure control. Probably drop attack aetiopathogenesis may be due to a sudden change in the otolith function of the utriculus and/or sacculus. At the same time flow mechanisms of cerebrospinal fluid (CSF) have a recognized impact on the origin of vestibular drop attack. According to this, the common origin of the perilymph and of the CSF may be an important argument in favour of the potential role of the fistula in the development of drop attacks.

Abstract
The sugar glider (Petaurus breviceps) is a small, arboreal, nocturnal, gliding mammalian possum belonging to the marsupial infraclass. Exotic marsupials, including sugar gliders, are becoming popular companion pets and, consequently, the risk of potential infections that can be transmitted to humans should be investigated. Data on the role of the sugar glider as a possible carrier of pathogenic and zoonotic bacteria are scarce and fragmentary. Therefore, this study is aimed at evaluating the prevalence of potentially zoonotic bacteria (Salmonella spp., Escherichia coli, Campylobacter spp., Pseudomonas spp., Klebsiella spp., Listeria monocytogenes and Yersinia enterocolitica) in 64 sugar gliders kept as pets in Italy. The highest prevalence of infection pertained to members of the family Enterobacteriaceae, in particular Citrobacter spp. (50%), Enterobacter spp. (28·1%) and Klebsiella pneumoniae (15·6%); Pseudomonas aeruginosa was isolated from 10 out of 64 samples (15·6%). All strains of Klebsiella pneumoniae exhibited some level of resistance to multiple antimicrobials (ampicillin, amoxicillin-clavulanic acid and doxycycline). SIGNIFICANCE AND IMPACT OF THE STUDY: The results of this study show that sugar gliders may act as carriers of potentially pathogenic agents for humans and other animal species, therefore caution should be exercised in the handling and contact with these animals.

Abstract
BACKGROUND
Background Glioblastoma multiforme (GBM) is characterized by short survival rates, thus generating a compelling need for more effective therapeutic schemes. Therapeutic approaches involving novel drugs must travel a long and expensive way in order to reach the bedside; drug repurposing and repositioning are viable strategies to develop therapies, involving shorter timelines and lower costs. Here we analyzed the activity of the antipsychotic drug chlorpromazine (CPZ) in hindering GBM growth in vitro and in vivo. The safety of this drug springs from six decades of clinical use as an antipsychotic. CPZ has been very recently identified as an inhibitor of the mitotic kinesin KSP/Eg5 and the AKT/mTOR pathway in human glioma cells.
MATERIAL AND METHODS
To explore CPZ pharmacodynamic properties, we assayed the effects of CPZ on several GBM cell lines growing in an anchorage-dependent manner or as neurospheres (cancer stem cells). Further experimentation using high-throughput proteomic and metabolomic platforms is underway.
RESULTS
In our hands CPZ, in the low micromolar range, strongly reduced GBM cell viability after 48 h in both anchorage-dependent cells (IC50=10 microM) and neurospheres (IC50=16 microM), cloning efficiency after 15 d (IC 50=4 and 9 microM, respectively), inducing also, at the respective IC50 concentrations for viability, spindle aberrations up to mitotic catastrophe in almost all cells, as highlighted by means of alpha-tubulin immunofluorescent staining. A Phase II clinical trial involving CPZ, in addition to the adjuvant phase of the Stupp protocol, in GBM patients carrying a hypo-methylated MGMT gene is now ongoing.
CONCLUSION
We proved the effectiveness of CPZ in potently hindering GBM cell growth, without sparing cancer stem cells. This last characteristic is important in order to overcome disease relapse and drug resistance. Recently, many drugs have been repositioned as potentially useful in GBM and for many of these, such as metformin, disulfiram, chloroquine, sirolimus and others, there are clinical trials that challenge them individually combined with the Stupp protocol. On the basis on our results, we consider the choice to undertake a Phase II clinical trial adding CPZ to TMZ in the adjuvant phase of the Stupp protocol as a rational and ethical option to be pursued

Abstract
Abstract
BACKGROUND
Patients with relapse of recurrent glioma have a poor outcome and limited treatment options. The aim of this study is to investigate the clinical benefit and tolerability of weekly intravenous administration of carboplatin-based monotherapy in adult glioma patients who had progressed from previous chemotherapy lines based on temozolomide and nitrosoureas
MATERIAL AND METHODS
This was a single arm, Phase II study. Eligibility criteria included progressive or recurrent malignant glioma after radiotherapy and chemotherapy-based treatments and Karnofsky Performance Status (KPS) > 60.
RESULTS
Thirty-two patients (median age: 43.5 y) were enrolled to receive weekly carboplatin monotherapy in intravenous mode of administration. The median duration of response was 7.3 months with an overall disease control rate of 31.3%. Median progression-free survival (PFS) was 2.3 months while overall survival (OS) was 5.5 months. Patients achieving clinical benefit exhibited a longer PFS (4.6 vs 1.5 months; p>0.001) and OS (7.9 vs 3.2 months; p=0.041) compared to those not achieving clinical benefit.
CONCLUSION
Our findings show that single agent, weekly, intravenous carboplatin may have a role in the treatment patients with recurrent malignant glioma

Abstract
Abstract
BACKGROUND
REGOMA trial showed that regorafenib (REG) significantly improved OS and PFS in patients (pts) with relapsed GBM with respect to lomustine (LOM). REG showed a different toxicity profile compared to LOM. Here, we report final results of the HRQoL assessment, a secondary end point.
MATERIAL AND METHODS
HRQoL was measured using the European Organization for Research and Treatment of Cancer (EORTC) core questionnaire (QLQ-C30) and brain module (QLQ-BN20) administered before any MRI assessments, every 8 weeks (+/- 2 weeks) until disease progression. To evaluate treatment impact on HRQoL, questionnaires at progression were excluded. Mixed-effect linear models were fitted for each of the HRQOL domain to examine the change over progression-free time within and between arms. The models included the time of questionnaire assessment, the treatment group and their interaction, as fixed effects, and a compound symmetry covariance structure for the random effects. Differences of at least 10 points were classified as a clinically meaningful change. To correct for multiple comparisons and to avoid type I error, the level of significance was set at P=0.01 (2-sided).
RESULTS
Of 119 randomized pts, 117 partecipated in the HRQoL evaluation, and 114 had a baseline assessment (n=56 REG; n=58 LOM). No statistically significant differences were observed in any generic or cancer specific domain during treatment in the REG and LOM arms, or between the two arms, except for the appetite loss scale which was significantly worse in PTS treated with REG (Global mean 14.7 (SD=28.6) vs 7.6 (SD=16.0); p=0.0081). The rate of pts with a clinically meaningful worsening for appetite loss was not statistically different between the two arms (9 out of 24 and 0 out of 13 in the REG and LOM arm, respectively;p=0.02).
CONCLUSION
In the REGOMA trial, HRQoL did not change during regorafenib treatment. Pts treated with regorafenib and lomustine reported no significant difference in HRQoL.

Abstract
Abstract
BACKGROUND
Malignant gliomas are aggressive primitive brain tumor in adults. Today, the standard of care is Temozolomide (TMZ) administered daily with radiation therapy, followed by adjuvant TMZ. TMZ treatment has been considered to have a low toxicity profile. However, during concomitant treatment some patient may develop a severe myelosuppression. This toxicity may be in some cases prolonged and lead to treatment discontinuation.
MATERIAL AND METHODS
We have retrospectively collected data from 5 italian neuro-oncological centers, about glioma patients who developed severe and prolonged hematological toxicity during concomitant chemoradiotherapy with TMZ. The purpouse of this study is to evaluate: percentage of patients receiving adjuvant chemotherapy after severe myelotoxicity; rate of toxicity observed during adjuvant chemotherapy.
RESULTS
54 glioma patients who developed myelosuppression of grade 3 or 4 were considered. Hystology was Glioblastoma in 45 patients (83%); 63% of patients were female. Myelotoxicity during concomitant phase occurred at a median of 4 weeks (range 1–8) from the start of treatment.After recovery of myelotoxicity 19 patients did not received any treatment while 35 (65%) were treated with chemotherapy (28 received standard TMZ, one TMZ with metronomic schedule, 2 lomustine and 4 other agents). Among patients treated with TMZ, 13 patients presented hematological toxicity grade 3–4 which required treatment discontinuation in 7 cases (20%).
CONCLUSION
we observed that 80 % of glioma patients presenting severe myelotoxicity during concomitant radiochemotherapy may be treated with maintenance TMZ after blood value recovery.

Abstract
BACKGROUND Neuromyelitis optica spectrum disorder (NMOSD) is a relapsing, autoimmune, inflammatory disorder that typically affects the optic nerves and spinal cord. At least two thirds of cases are associated with aquaporin-4 antibodies (AQP4-IgG) and complement-mediated damage to the central nervous system. In a previous small, open-label study involving patients with AQP4-IgG-positive disease, eculizumab, a terminal complement inhibitor, was shown to reduce the frequency of relapse. METHODS In this randomized, double-blind, time-to-event trial, 143 adults were randomly assigned in a 2:1 ratio to receive either intravenous eculizumab (at a dose of 900 mg weekly for the first four doses starting on day 1, followed by 1200 mg every 2 weeks starting at week 4) or matched placebo. The continued use of stable-dose immunosuppressive therapy was permitted. The primary end point was the first adjudicated relapse. Secondary outcomes included the adjudicated annualized relapse rate, quality-of-life measures, and the score on the Expanded Disability Status Scale (EDSS), which ranges from 0 (no disability) to 10 (death). RESULTS The trial was stopped after 23 of the 24 prespecified adjudicated relapses, given the uncertainty in estimating when the final event would occur. The mean (±SD) annualized relapse rate in the 24 months before enrollment was 1.99±0.94; 76% of the patients continued to receive their previous immunosuppressive therapy during the trial. Adjudicated relapses occurred in 3 of 96 patients (3%) in the eculizumab group and 20 of 47 (43%) in the placebo group (hazard ratio, 0.06; 95% confidence interval [CI], 0.02 to 0.20; P<0.001). The adjudicated annualized relapse rate was 0.02 in the eculizumab group and 0.35 in the placebo group (rate ratio, 0.04; 95% CI, 0.01 to 0.15; P<0.001). The mean change in the EDSS score was -0.18 in the eculizumab group and 0.12 in the placebo group (least-squares mean difference, -0.29; 95% CI, -0.59 to 0.01). Upper respiratory tract infections and headaches were more common in the eculizumab group. There was one death from pulmonary empyema in the eculizumab group. CONCLUSIONS Among patients with AQP4-IgG-positive NMOSD, those who received eculizumab had a significantly lower risk of relapse than those who received placebo. There was no significant between-group difference in measures of disability progression.

Abstract
An infected non-union is a major and potentially devastating complication following bone fractures. It is often debilitating for the patients, physically and psychologically, because of its long healing period and emotional toll on patient and caregivers. Different surgical procedures (in one or two stages) are described in literature for its treatment. These range from external fixation (axial or circular) to internal fixation (nails or plates) associated or not with different types of biological support/augmentation (iliac crest bone graft, platelet rich plasma, bone morphogenic protein, etc.). This case report is about a 19 y.o. man affected by an infected non-union of the femoral shaft, who had to undergo a revision surgery a year after his accident. The treatment chosen by the senior author was the following one stage procedure: external fixator removal, surgical debridement, reduction and fixation of the fracture with a locked plate (internal fixator), bone graft and antibiotic cement usage. The use of new iliac crest bone graft after three months was necessary to obtain radiographic and clinical healing with great patient's satisfaction. The autologous iliac bone graft was chosen because it was necessary to give the patient the highest chance of healing. Despite the great experimental and clinical efforts to stimulate the biological healing process through the use of growth factors, stem cells, tissue scaffolds and other methods, today the gold standard of bone graft is still the autologous cancellous bone from the iliac crest.

Formation of stromatolite lamina at the interface of oxygenic-anoxygenic photosynthesis. GEOBIOLOGY 2018; 16:378-398.

Abstract
In modern stromatolites, mineralization results from a complex interplay between microbial metabolisms, the organic matrix, and environmental parameters. Here, we combined biogeochemical, mineralogical, and microscopic analyses with measurements of metabolic activity to characterize the mineralization processes and products in an emergent (<18 months) hypersaline microbial mat. While the nucleation of Mg silicates is ubiquitous in the mat, the initial formation of a Ca-Mg carbonate lamina depends on (i) the creation of a high-pH interface combined with a major change in properties of the exopolymeric substances at the interface of the oxygenic and anoxygenic photoautotrophic layers and (ii) the synergy between two major players of sulfur cycle, purple sulfur bacteria, and sulfate-reducing bacteria. The repetition of this process over time combined with upward growth of the mat is a possible pathway leading to the formation of a stromatolite.

Fast mapping word meanings across trials: Young children forget all but their first guess. Cognition 2018; 177:177-188.

Abstract
Do children learn a new word by tracking co-occurrences between words and referents across multiple instances ("cross-situational learning" models), or is word-learning a "one-track" process, where learners maintain a single hypothesis about the possible referent, which may be verified or falsified in future occurrences ("propose-but-verify" models)? Using a novel word-learning task, we ask which learning procedure is utilized by preschool-aged children. We report on findings from three studies comparing the word-learning strategies across different populations of child learners: monolingual English learners, Spanish - English dual language learners, and learners at risk for language-delay. In all three studies, we ask what, if anything, is retained from prior exposures and whether the amount of information retained changes as children get older. The ability to make a good initial hypothesis was a function of various factors, including language ability and experience, but across-the-board, children were no better than chance after a wrong initial hypothesis. This suggests that children do not retain multiple meaning hypotheses across learning instances, lending support to the propose-but-verify models.

Abstract
OBJECTIVES Reptiles are considered an important reservoir of Salmonella species. This study evaluated the prevalence of Salmonella species in different species of gecko kept as pets in Italy. MATERIALS AND METHODS Faecal swab samples were collected from 70 clinically healthy geckos and examined for Salmonella species by culture that were then serotyped. RESULTS Salmonella species were isolated from 24 of 70 (34·3%) samples. Eighteen isolates expressed resistance to ceftazidime and four isolates to ampicillin. CLINICAL SIGNIFICANCE Salmonella spp. can be isolated from apparently healthy captive gecko which should be considered as a potential source of infection for humans and other companion animals.

Post-operative nebulized sodium hyaluronate versus spray after functional endoscopic sinus surgery for chronic rhinosinusitis. J BIOL REG HOMEOS AG 2017; 31:81-89.

Abstract
We prospectively evaluated the efficacy of nebulized Hyaluronic Acid (HA) as an adjuvant treatment to hasten the improvement of nasal respiration and to minimize patients discomfort in the postoperative functional endoscopic sinus surgery (FESS) for chronic rhino-sinusitis (CRS). We enrolled 33 CRS adult patients who underwent endoscopic functional sinus surgery. They were randomly assigned into two groups: Spray-Sol group (18 patients) with HA nebulized with a new nasal device named Spray-Sol and Spray group (15 patients) with a HA nebulized with a common spray. Both groups were treated twice daily for 4 weeks. CRS questionnaire, Visual analogic scale (VAS) and nasal endoscopy were used to assess the outcomes of the treatments during the 1st month of follow up. The mean VAS score of the Spray-Sol group at 2 weeks was significantly lower than the Spray group (5.2±2.1 vs 10.5±3.7; p less than 0.05). The VAS score remained significantly lower in the Spray-Sol group also at the 4 weeks (2.9±0.8 vs 6.1±3.4; p less than 0.05). The CRS score was significantly better at week 2 and 4 in both groups in comparison with baseline values, with better results in the Spray-Sol group. Since the first visit the Spray-Sol group also showed significantly lower crusts, edema and secretions than the Spray group (p less than 0.05). The compliance to treatment was similar in both groups. The results of this prospective study suggest a role nebulized of HA through new device (Spray-sol) as a supportive treatment for faster improvement of nasal respiration, also minimizing patient discomfort, promoting nasal mucosa healing in postoperative FESS for CRS.
