L’ESPERIENZA DELLA SICILIA QUALE REGIONE CAPOFILA NELLA INTRODUZIONE DELLA VACCINAZIONE UNIVERSALE CONTRO I ROTAVIRUS

La gastroenterite da rotavirus (GARV) rappresenta uno dei principali bisogni assistenziali durante l’età pediatrica. Purtroppo, in Italia, in assenza di notifica obbligatoria e di specifici sistemi di sorveglianza, le uniche valutazioni epidemiologiche disponibili sulle GARV sono rese possibili dall’analisi delle ospedalizzazioni. Il presente lavoro ha avuto l’obiettivo di valutare le ospedalizzazioni per GARV e per intussuscezione, avvenute in Sicilia in soggetti di età compresa tra 0 e 60 mesi, negli anni 2003-2012 (periodo prevaccinale) e 2013 (anno di introduzione della vaccinazione antirotavirus). Nel periodo in esame si sono osservate 9.886 ospedalizzazioni per GARV con una media annua di 899 casi. La maggior parte dei ricoveri (62,3%) è stata registrata nella fascia di età compresa tra 0 e 2 anni con una progressiva riduzione negli anni di vita successivi. Durante il 2013 si è osservata una copertura vaccinale regionale attestatasi tra il 30 ed il 40% per la prima dose ed il 25-35% per la seconda dose. Nello stesso anno si è assistito ad una riduzione dei casi di GARV di circa il 38,9% nei soggetti di età 0-5 anni (931 casi/anno nel 2003-2012 vs. 569 nel 2013) e superiore al 50% nella fascia di età 0-11 mesi (277 casi/anno nel 2003-2012 vs. 137 nel 2013). Diversamente, nel 2013 il numero di ospedalizzazioni per intussuscezione in soggetti di età compresa tra 0 ed 11 mesi si è mantenuta in linea con quanto osservato in epoca prevaccinale (15 casi nel 2013 vs. 15,4 casi/anno osservati in media tra 2003 e 2012). I dati presentati evidenziano l’importante peso assistenziale che le GARV hanno annualmente in Sicilia e supportano l’efficacia della vaccinazione nella riduzione significativa dei casi di ospedalizzazione per GARV in assenza di incrementi di rischio di intussuscezione

Individual and contextual determinants of inter-regional mobility in cancer patients

This paper will present an investigation of inter-regional mobility in patients with a diagnosis of cancer. By virtue of the availability of geocoded information relating to a patient's place of residence, the effect of socio-economic status and other individual characteristics regarding inter-regional mobility will be analysed by means of multilevel logit models. The results demonstrate the influence of age and comorbidity on mobility propensity, in addition to the treatment type, which plays a role in patient mobility. As contextual determinants, patients residing in less deprived areas show greater mobility than those who reside in materially deprived areas. The extent of patient mobility, and its dependence on their socio-economic status raises issues of equity, as well as regional policy considerations

Moringa oleifera Protects SH-SY5YCells from DEHP-Induced Endoplasmic Reticulum Stress and Apoptosis

Moringa oleifera (MO) is a medicinal plant that has been shown to possess antioxidant, anticarcinogenic and antibiotic activities. In a rat model, MO extract (MOe) has been shown to have a protective effect against brain damage and memory decline. As an extending study, here, we have examined the protective effect of MOe against oxidative stress and apoptosis caused in human neuroblastome (SH-SY5Y) cells by di-(2-ethylhexyl) phthalate (DEHP), a plasticizer known to induce neurotoxicity. Our data show that MOe prevents oxidative damage by lowering reactive oxygen species (ROS) formation, restoring mitochondrial respiratory chain complex activities, and, in addition, by modulating the expression of vitagenes, i.e., antioxidant proteins Nrf2 and HO-1. Moreover, MOe prevented neuronal damage by partly inhibiting endoplasmic reticulum (ER) stress response, as indicated by decreased expression of CCAAT-enhancer-binding protein homologous protein (CHOP) and Glucose-regulated protein 78 (GRP78) proteins. MOe also protected SH-SY5Y cells from DEHP-induced apoptosis, preserving mitochondrial membrane permeability and caspase-3 activation. Our findings provide insight into understanding of molecular mechanisms involved in neuroprotective effects by MOe against DEHP damag

Hydrogen Sulfide and Carnosine: Modulation of Oxidative Stress and Inflammation in Kidney and Brain Axis

Emerging evidence indicates that the dysregulation of cellular redox homeostasis and chronic inflammatory processes are implicated in the pathogenesis of kidney and brain disorders. In this light, endogenous dipeptide carnosine (β-alanyl-L-histidine) and hydrogen sulfide (H2S) exert cytoprotective actions through the modulation of redox-dependent resilience pathways during oxidative stress and inflammation. Several recent studies have elucidated a functional crosstalk occurring between kidney and the brain. The pathophysiological link of this crosstalk is represented by oxidative stress and inflammatory processes which contribute to the high prevalence of neuropsychiatric disorders, cognitive impairment, and dementia during the natural history of chronic kidney disease. Herein, we provide an overview of the main pathophysiological mechanisms related to high levels of pro-inflammatory cytokines, including interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and neurotoxins, which play a critical role in the kidney–brain crosstalk. The present paper also explores the respective role of H2S and carnosine in the modulation of oxidative stress and inflammation in the kidney–brain axis. It suggests that these activities are likely mediated, at least in part, via hormetic processes, involving Nrf2 (Nuclear factor-like 2), Hsp 70 (heat shock protein 70), SIRT-1 (Sirtuin-1), Trx (Thioredoxin), and the glutathione system. Metabolic interactions at the kidney and brain axis level operate in controlling and reducing oxidant-induced inflammatory damage and therefore, can be a promising potential therapeutic target to reduce the severity of renal and brain injuries in humans

Growth, electronic and electrical characterization of Ge-Rich Ge-Sb-Te alloy

In this study, we deposit a Ge-rich Ge-Sb-Te alloy by physical vapor deposition (PVD) in the amorphous phase on silicon substrates. We study in-situ, by X-ray and ultraviolet photoemission spectroscopies (XPS and UPS), the electronic properties and carefully ascertain the alloy composition to be GST 29 20 28. Subsequently, Raman spectroscopy is employed to corroborate the results from the photoemission study. X-ray diffraction is used upon annealing to study the crystallization of such an alloy and identify the effects of phase separation and segregation of crystalline Ge with the formation of grains along the [111] direction, as expected for such Ge-rich Ge-Sb-Te alloys. In addition, we report on the electrical characterization of single memory cells containing the Ge-rich Ge-Sb-Te alloy, including I-V characteristic curves, programming curves, and SET and RESET operation performance, as well as upon annealing temperature. A fair alignment of the electrical parameters with the current state-of-the-art of conventional (GeTe)n-(Sb2Te3)m alloys, deposited by PVD, is found, but with enhanced thermal stability, which allows for data retention up to 230 °C

Bone density and genomic analysis unfold cold adaptation mechanisms of ancient inhabitants of Tierra del Fuego

The Fuegians, ancient inhabitants of Tierra del Fuego, are an exemplary case of a cold-adapted population, since they were capable of living in extreme climatic conditions without any adequate clothing. However, the mechanisms of their extraordinary resistance to cold remain enigmatic. Brown adipose tissue (BAT) plays a crucial role in this kind of adaptation, besides having a protective role on the detrimental effect of low temperatures on bone structure. Skeletal remains of 12 adult Fuegians, collected in the second half of XIX century, were analyzed for bone mineral density and structure. We show that, despite the unfavorable climate, bone mineral density of Fuegians was close to that seen in modern humans living in temperate zones. Furthermore, we report significant differences between Fuegians and other cold-adapted populations in the frequency of the Homeobox protein Hox-C4 (HOXC4) rs190771160 variant, a gene involved in BAT differentiation, whose identified variant is predicted to upregulate HOXC4 expression. Greater BAT accumulation might therefore explain the Fuegians extreme cold-resistance and the protection against major cold-related damage. These results increase our understanding of how ecological challenges have been important drivers of human–environment interactions during Humankind history

Unpublished Mediterranean and Black Sea records of marine alien, cryptogenic, and neonative species

To enrich spatio-temporal information on the distribution of alien, cryptogenic, and neonative species in the Mediterranean and the Black Sea, a collective effort by 173 marine scientists was made to provide unpublished records and make them open access to the scientific community. Through this effort, we collected and harmonized a dataset of 12,649 records. It includes 247 taxa, of which 217 are Animalia, 25 Plantae and 5 Chromista, from 23 countries surrounding the Mediterranean and the Black Sea. Chordata was the most abundant taxonomic group, followed by Arthropoda, Mollusca, and Annelida. In terms of species records, Siganus luridus, Siganus rivulatus, Saurida lessepsianus, Pterois miles, Upeneus moluccensis, Charybdis (Archias) longicollis, and Caulerpa cylindracea were the most numerous. The temporal distribution of the records ranges from 1973 to 2022, with 44% of the records in 2020–2021. Lethrinus borbonicus is reported for the first time in the Mediterranean Sea, while Pomatoschistus quagga, Caulerpa cylindracea, Grateloupia turuturu, and Misophria pallida are first records for the Black Sea; Kapraunia schneideri is recorded for the second time in the Mediterranean and for the first time in Israel; Prionospio depauperata and Pseudonereis anomala are reported for the first time from the Sea of Marmara. Many first country records are also included, namely: Amathia verticillata (Montenegro), Ampithoe valida (Italy), Antithamnion amphigeneum (Greece), Clavelina oblonga (Tunisia and Slovenia), Dendostrea cf. folium (Syria), Epinephelus fasciatus (Tunisia), Ganonema farinosum (Montenegro), Macrorhynchia philippina (Tunisia), Marenzelleria neglecta (Romania), Paratapes textilis (Tunisia), and Botrylloides diegensis (Tunisia).peer-reviewe

Knowledge, Attitudes, and Practices on Energy Drink Consumption and Side Effects in a Cohort of Medical Students

The purpose of this study was to evaluate knowledge, attitudes, and practices concerning energy drink consumption and the prevalence of side effects among medical students. Twenty-two percent of respondents were regular users, particularly men (p <.0005). Users were younger (p =.027) and drank alcohol more frequently (p =.008) than "non-users." Forty-nine percent consumed alcohol associated with energy drinks. Forty-five percent of medical students declared side effects after energy drink consumption, such as palpitations (35%), insomnia (21%), and irritability (20%). The study confirms a large use of energy drinks among students and the occurrence of side effects. The use of energy drinks may influence the ingestion of large amounts of alcohol

Hospitalisation of children aged 0-59 months with rotavirus gastro-enteritis before the introduction of routine vaccination (Sicily 2003-2012).

Background: Recent evidence demonstrates that rotavirus vaccination is the best strategy for reducing rotavirus gastro-enteritis (RVGE) in young children. Aims: This study describes the epidemiology of RVGE hospitalisation of Sicilian children before universal rotavirus vaccination was introduced into the regional immunisation programme in January 2013. Methods: An observational study was undertaken by analyzing data obtained from the Regional Hospital Discharge database, including hospitalisation from 2003 to 2012 of subjects aged 0-59 months who lived in Sicily. Children discharged with the rotavirus-specific ICD-9-CM code of 008·61 on first or any diagnosis stage were considered to be RVGE cases. Results: From 2003 to 2012, 9317 children (median age 19 months, M/F ratio 1·19) were hospitalised with a diagnosis of RVGE. During the study period, annual rates of hospitalisation were between 2·64 and 4·68 cases/1000 children (mean 3·74 cases). Incidence rates were higher in children aged 6-11 months (8·85/1,000 children/year), decreasing significantly with age (P&lt;0·001). RVGE hospitalisation peaked during winter and spring with a statistically significant downward trend throughout summer and autumn. Conclusion: During the study period, the cumulative risk of hospitalisation with RVGE was determined to be about one in 54 Sicilian children in the 1st 5 years of life. Although the present study cannot be considered a proper pharmaco-economic evaluation, the findings suggest that in Sicily the health and economic burden of RVGE hospitalisation strongly supports the introduction of rotavirus vaccination into the regional immunisation programme as a probably cost-saving intervention
