Introduzione l’alopecia da chemioterapia (CIA) ha un impatto emotivo negativo sugli assistiti in quanto vissuta come compromissione della propria immagine corporea e segno evidente della malattia in atto. Obiettivo comprendere il vissuto e le emozioni provate da persone in follow-up oncologico che hanno sofferto di alopecia indotta da chemioterapia. Materiali e metodi studio qualitativo fenomenologico condotto attraverso interviste semi-strutturate su un campione di convenienza di pazienti adulti oncologici tra giugno e dicembre 2022. Analisi effettuata attraverso il metodo Colaizzi da due esperti. Risultati sono state effettuate 12 interviste da cui sono emerse 4 tematiche principali: (I) emozioni vissute dagli assistiti dopo la perdita dei capelli, cioè come gli assistiti hanno vissuto l’esperienza relativa alla perdita dei capelli. (II) Alterazione della percezione del proprio aspetto fisico; la percezione di sé e le annesse reazioni emotive. (III) Relazione con gli altri ossia i cambiamenti del rapporto con gli altri. (IV) Infine, le persone più vicine durante i cambiamenti dell’identità personale e dell’immagine corporea dove si evidenzia il supporto educativo ed emotivo multidisciplinare. Discussione e Conclusioni i risultati sono in linea con la letteratura scientifica ed evidenziano un disagio dovuto alla CIA associato negativamente all’immagine corporea ed al benessere psico-sociale. Gli operatori sanitari devono acquisire consapevolezza dell’entità del disagio per interventi educativi mirati a sviluppare strategie di coping efficaci.

The post-COVID-19 condition is defined by the World Health Organization as the persistence of symptoms or development of new symptoms three months after the initial SARS-CoV-2 infection, lasting for at least two months without a clear explanation. Neuropsychiatric disorders associated with this condition include asthenia, memory and concentration problems, and sleep disturbances. Our study aims to investigate sleep patterns following SARS-CoV-2 infection using EEG findings and a sleep quality questionnaire completed by parents (Sleep Disturbance Scale for Children—SDSC). Notably, our investigation is based on a convenience sample. The patients in our sample, aged 1 to 14 years, are not currently taking any medications; rather, they are undergoing follow-up assessments at the Child Neuropsychiatry department of the University Hospital of Messina for neurodevelopmental evaluations. Specifically, we are analyzing amplitude and power spectrum data in the first five minutes of NREM2 sleep, calculated from EEG recordings obtained via bipolar leads within three months after the onset of the disease. These results will be compared with controls performed on the same subjects in the six months preceding the infection. The focus of the study was sleep spindles, which are generated by the thalamocortical systems and play a role in sleep modulation, memory, and learning. Preliminary analysis suggests a predominant increase in the slow component of the spindles in the right-frontal lead.

Increased oxidative stress and defective mitochondrial functioning are shared features among many brain disorders. The aim of this study was to verify retrospectively the clinical efficacy and safety of a metabolic support therapy with Q10 ubiquinol, vitamin E and complex-B vitamins in various neurodevelopmental disorders. This retrospective chart review study included 59 patients (mean age 10.1 ± 1.2 y.o., range 2.5–39 years; M:F = 2.47:1), diagnosed with Autism Spectrum Disorder (n = 17), Autism Spectrum Disorder with co-morbid Intellectual Disability (n = 19), Intellectual Disability or Global Developmental Delay (n = 15), Attention-Deficit/Hyperactivity Disorder (n = 3) and Intellectual Disability in Phelan-McDermid syndrome due to chr. 22q13.33 deletion (n = 5). After a minimum of 3 months of therapy, a positive outcome was recorded in 45/59 (76.27%) patients, with Clinical Global Impression—Improvement scores ranging between 1 (“very much improved”) and 3 (“minimally improved”). The most widespread improvements were recorded in cognition (n = 26, 44.1%), adaptative functioning (n = 26, 44.1%) and social motivation (n = 19, 32.2%). Improvement rates differed by diagnosis, being observed most consistently in Phelan-McDermid Syndrome (5/5, 100%), followed by Intellectual Disability/Global Developmental Delay (13/15, 86.7%), Autism Spectrum Disorder with co-morbid Intellectual Disability (15/19, 78.9%), Autism Spectrum Disorder (11/17, 64.7%) and ADHD (1/3, 33.3%). No significant adverse event or side effect leading to treatment discontinuation were recorded. Mild side effects were reported in 18 (30.5%) patients, with the most frequent being increased hyperactivity (9/59, 15.3%). This retrospective chart review suggests that metabolic support therapy with Q10 ubiquinol, vitamin E and complex-B vitamins is well tolerated and produces some improvement in the majority of patients with neurodevelopmental disorders, especially in the presence of intellectual disability. Randomized controlled trials for each single neurodevelopmental disorder are now warranted to conclusively demonstrate the efficacy of these mitochondrial bioenergetic and antioxidant agents and to estimate their therapeutic effect size.

Si306, a pyrazolo[3,4-d]pyrimidine derivative recently identified as promising anticancer agent, has shown favorable in vitro and in vivo activity profile against neuroblastoma (NB) models by acting as a competitive inhibitor of c-Src tyrosine kinase. Nevertheless, Si306 antitumor activity is associated with sub-optimal aqueous solubility, which might hinder its further development. Drug delivery systems were here developed with the aim to overcome this limitation, obtaining suitable formulations for more efficacious in vivo use. Si306 was encapsulated in pegylated stealth liposomes, undecorated or decorated with a monoclonal antibody able to specifically recognize and bind to the disialoganglioside GD2 expressed by NB cells (LP[Si306] and GD2-LP[Si306], respectively). Both liposomes possessed excellent morphological and physio-chemical properties, maintained over a period of two weeks. Compared to LP[Si306], GD2-LP[Si306] showed in vitro specific cellular targeting and increased cytotoxic activity against NB cell lines. After intravenous injection in healthy mice, pharmacokinetic profiles showed increased plasma exposure of Si306 when delivered by both liposomal formulations, compared to that obtained when Si306 was administered as free form. In vivo tumor homing and cytotoxic effectiveness of both liposomal formulations were finally tested in an orthotopic animal model of NB. Si306 tumor uptake resulted significantly higher when encapsulated in GD2-LP, compared to Si306, either free or encapsulated into untargeted LP. This, in turn, led to a significant increase in survival of mice treated with GD2-LP[Si306]. These results demonstrate a promising antitumor efficacy of Si306 encapsulated into GD2-targeted liposomes, supporting further therapeutic developments in pre-clinical trials and in the clinic for NB.

Incidents of violence by healthcare users against staff have been considered as sentinel events. New forms of aggression, i.e., cyberbullying, have emerged with the advent of social networks. Medical literature includes some reports about workplace cyberbullying on nurses and young doctors by colleagues/supervisors, but not by users. To investigate cyberbullying on healthcare providers via social networks, we carried out an exploratory quali-quantitative study, researching and analyzing posts and comments relating to a local Health Trust (ASL5) in Italy, published from 2013 until May 2020 on healthcare worker aggressions on social networks on every local community’s Facebook page. We developed a thematic matrix through an analysis of the most recurring meaning categories (framework method). We collected 217 texts (25 posts and 192 comments): 26% positive and 74% negative. Positive posts were shared about ten times more than negative ones. Negative comments received about double the “Likes” than the positive ones. Analysis highlighted three main meaning categories: 1. lack of adequate and functional structures; 2. negative point of view (POV) towards some departments; 3. positive POV towards others. No significant differences were observed between the various categories of healthcare workers (HCW). Geriatric, medical wards and emergency department were the most frequent targets of negative comments. All the texts referred to first-line operators except for one. Online violence against HCW is a real, largely unknown, problem that needs immediate and concrete attention for its potentially disastrous consequences. Compared to traditional face-to-face bullying, it can be more dangerous as it is contagious and diffusive, without spatial, temporal or personal boundaries.

Glioblastoma (GBM), as the most aggressive brain tumor, displays a high expression of Src tyrosine kinase, which is involved in the survival, migration, and invasiveness of tumor cells. Thus, Src emerged as a potential target for GBM therapy. The effects of Src inhibitors pyrazolo[3,4-d]pyrimidines, Si306 and its prodrug pro-Si306 were investigated in human GBM cell lines (U87 and U87-TxR) and three primary GBM cell cultures. Primary GBM cells were more resistant to Si306 and pro-Si306 according to the 3-(4,5-Dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. However, the ability of all GBM cells to degrade the extracellular matrix was considerably compromised after Si306 and pro-Si306 applications. Besides reducing the phosphorylation of Src and its downstream signaling pathway components, both compounds decreased the phosphorylated form of focal adhesion kinase (FAK) and epidermal growth factor receptor (EGFR) expression, showing the potential to suppress the aggressiveness of GBM. In vivo, Si306 and pro-Si306 displayed an anti-invasive effect against U87 xenografts in the zebrafish embryo model. Considering that Si306 and pro-Si306 are able to cross the blood–brain barrier and suppress the spread of GBM cells, we anticipate their clinical testing in the near future. Moreover, the prodrug showed similar efficacy to the drug, implying the rationality of its use in clinical settings.

Overexpression of P-glycoprotein (P-gp) and other ATP-binding cassette (ABC) transporters in multidrug resistant (MDR) cancer cells is responsible for the reduction of intracellular drug accumulation, thus decreasing the efficacy of chemotherapeutics. P-gp is also found at endothelial cells’ membrane of the blood-brain barrier, where it limits drug delivery to central nervous system (CNS) tumors. We have previously developed a set of pyrazolo[3,4-d]pyrimidines and their prodrugs as novel Src tyrosine kinase inhibitors (TKIs), showing a significant activity against CNS tumors in in vivo. Here we investigated the interaction of the most promising pair of drug/prodrug with P-gp at the cellular level. The tested compounds were found to increase the intracellular accumulation of Rho 123, and to enhance the efficacy of paclitaxel in P-gp overexpressing cells. Encouraging pharmacokinetics properties and tolerability in vivo were also observed. Our findings revealed a novel role of pyrazolo[3,4-d]pyrimidines which may be useful for developing a new effective therapy in MDR cancer treatment, particularly against glioblastoma.

The release of Quentin Tarantino’s Django Unchained in 2012 has stirred a renewed interest in Western films. The film pays homage to the Italian sub-genre of Spaghetti Westerns and has the ambition to create a completely new genre, the “Southern”. This constitutes an important evolution in the history of the genre, especially after the transformation carried about by the “Eurowesterns” between the 1960s and the 1970s. In this paper I will consider the importance of the Italian and European Westerns in the development of the genre in recent times, both in Europe and the rest of the world. With its blending of American Western and Spaghetti Western, Django Unchained is an innovative contribution to a tradition started in the 1960s and, at the same time, an anticipation of a potential development of the genre.
