Segmental transverse colectomy. Minimally invasive versus open approach: results from a multicenter collaborative study
The role of minimally invasive surgery in the treatment of transverse colon cancer is still controversial. The aim of this study is to investigate the advantages of a totally laparoscopic technique comparing open versus laparoscopic/robotic approach. Three hundred and eighty-eight patients with transverse colon cancer, treated with a segmental colon resection, were retrospectively analyzed. Demographic data, tumor stage, operative time, intraoperative complications, number of harvested lymph nodes and recovery outcomes were recorded. Recurrences and death were also evaluated during the follow-up. No differences were found between conventional and minimally invasive surgery, both for oncological long-term outcomes (recurrence rate p = 0.28; mortality p = 0.62) and postoperative complications (overall rate p = 0.43; anemia p = 0.78; nausea p = 0.68; infections p = 0.91; bleeding p = 0.62; anastomotic leak p = 0.55; ileus p = 0.75). Nevertheless, recovery outcomes showed statistically significant differences in favor of minimally invasive surgery in terms of time to first flatus (p = 0.001), tolerance to solid diet (p = 0.017), time to first mobilization (p = 0.001) and hospital stay (p = 0.004). Compared with laparoscopic approach, robotic surgery showed significantly better results for time to first flatus (p = 0.001), to first mobilization (p = 0.005) and tolerance to solid diet (p = 0.001). Finally, anastomosis evaluation confirmed the superiority of intracorporeal approach which showed significantly better results for time to first flatus (p = 0.001), to first mobilization (p = 0.003) and tolerance to solid diet (p = 0.001); moreover, we recorded a statistical difference in favor of intracorporeal approach for infection rate (p = 0.04), bleeding (p = 0.001) and anastomotic leak (p = 0.03). Minimally invasive approach is safe and effective as the conventional open surgery, with comparable oncological results but not negligible advantages in terms of recovery outcomes. Moreover, we demonstrated that robotic approach may be considered a valid option and an intracorporeal anastomosis should always be preferred

Emergence of assortative mixing between clusters of cultured neurons
The analysis of the activity of neuronal cultures is considered to be a good proxy of the functional connectivity of in vivo neuronal tissues. Thus, the functional complex network inferred from activity patterns is a promising way to unravel the interplay between structure and functionality of neuronal systems. Here, we monitor the spontaneous self-sustained dynamics in neuronal cultures formed by interconnected aggregates of neurons (clusters). Dynamics is characterized by the fast activation of groups of clusters in sequences termed bursts. The analysis of the time delays between clusters' activations within the bursts allows the reconstruction of the directed functional connectivity of the network. We propose a method to statistically infer this connectivity and analyze the resulting properties of the associated complex networks. Surprisingly enough, in contrast to what has been reported for many biological networks, the clustered neuronal cultures present assortative mixing connectivity values, meaning that there is a preference for clusters to link to other clusters that share similar functional connectivity, as well as a rich-club core, which shapes a"connectivity backbone" in the network. These results point out that the grouping of neurons and the assortative connectivity between clusters are intrinsic survival mechanisms of the culture
Neither hereditary periodic fever nor periodic fever, aphthae, pharingitis, adenitis: Undifferentiated periodic fever in a tertiary pediatric center
AIM: To describe the frequency and clinical characteristics of patients with undifferentiated periodic fever (UPF) and to investigate whether a clinical classification of UPF based on the PRINTO-Eurofever score can help predicting the response to treatment and the outcome at follow-up. METHODS: Clinical and therapeutic information of patients with recurrent fever who presented at a single pediatric rheumatology center from January 2006 through April 2016 were retrospectively collected. Patients with a clinical suspicion of hereditary periodic fever (HPF) syndrome and patients with clinical picture of periodic fever, aphthae, pharingitis, adenitis (PFAPA) who were refractory to tonsillectomy underwent molecular analysis of five HPF-related genes: MEFV (NM_000243.2), MVK (NM_000431.3), TNFRSF1A (NM_001065.3), NLRP3 (NM_001079821.2), NLRP12 (NM_001277126.1). All patients who had a negative genetic result were defined as UPF and further investigated. PRINTO-Eurofever score for clinical diagnosis of HPF was calculated in all cases. RESULTS: Of the 221 patients evaluated for periodic fever, twelve subjects with a clinical picture of PFAPA who were refractory to tonsillectomy and 22 subjects with a clinical suspicion of HPF underwent genetic analysis. Twenty-three patients (10.4%) resulted negative and were classified as UPF. The median age at presentation of patients with UPF was 9.5 mo (IQR 4-24). Patients with UPF had a higher frequency of aphthae (52.2% vs 0%, P = 0.0026) and musculoskeletal pain (65.2% vs 18.2%, P = 0.0255) than patients with genetic confirmed HPF. Also, patients with UPF had a higher frequency of aphthous stomatitis (52.2% vs 10.7%, P < 0.0001), musculoskeletal pain (65.2% vs 8,0%, P < 0.0001), and abdominal pain (52.2% vs 4.8%, P < 0.0001) and a lower frequency of pharyngitis (56.6% vs 81.3%, P = 0.0127) compared with typical PFAPA in the same cohort. Twenty-one of 23 patients with UPF (91.3%) received steroids, being effective in 16; 13 (56.2%) were given colchicine, which was effective in 6. Symptoms resolution occurred in 2 patients with UPF at last follow-up. Classification according to the PRINTO-Eurofever score did not correlate with treatment response and prognosis. CONCLUSION: UPF is not a rare diagnosis among patients with periodic fever. Clinical presentation place UPF half way on a clinical spectrum between PFAPA and HPF. The PRINTO-Eurofever score is not useful to predict clinical outcome and treatment response in these patients
Productive Performance and Meat Characteristics of Kids Fed a Red Orange and Lemon Extract
This study evaluates the animal performance and meat characteristics of 60 Saanen suckling kids daily fed a red orange and lemon extract (RLE), rich in anthocyanins. In our methodology, after colostrum administration, animals are randomly assigned to two treatments: Treatment group (Group RLE; n = 30) that received RLE (90 mg/kg live body weight) as oral food additive, and a control group (Group CON; n = 30) that received a standard diet. Animals are slaughtered after 40 days. The RLE administration did not influence daily weight gain, carcass measurements, or incidences (expressed as a percentage) of different anatomical regions on the whole carcass weight. On the contrary, RLE supplementation significantly improved the oxidative profile of the meat seven days after slaughtering, as demonstrated by the reduced levels of thiobarbituric acid reactive substances (TBARS; p < 0.01) and hydroperoxides (p < 0.01) in Group RLE compared to Group CON. A significant influence of RLE administration is observed on day 7 for yellowness (p < 0.01). There are also lower saturated and higher monounsaturated and polyunsaturated fatty acids concentration in Group RLE meat (p < 0.01), which also shows lower atherogenic and thrombogenic indexes (p < 0.01) compared to Group CON. The study demonstrates that the supplementation of a diet with RLE rich in anthocyanins is effective to improve the meat quality
Linking accounts for ecosystem services and benefits to the economy through bridging (LISBETH)
The acronym LISBETH stands for LInking accounts for ecosystem Services and Benefits to the Economy THrough bridging. LISBETH is based on INCA (Integrated system for Natural Capital Accounting) and is meant to facilitate the use of INCA accounts in traditional economic analytical tools. Three practical examples are described and commented on. The first application shows how to combine crop provision accounts with the conventional accounts related to agricultural products and their trade. Combined account presentations are useful for policymakers, not only for technical analytical purposes but also for communicating with a wider non-technical audience. The second application shows how to build consumption-based accounts using multiregional input–output tables; in our example we assess the water purification service embedded in traded crops. Consumption remains in fact the ultimate driver behind production processes. The third application shows how to link ecosystem services accounts to general equilibrium models to assess the economic impacts generated by changes in ecosystem services; in our example we address the impact of invasive alien species on pollination and in turn on pollination-dependent crops and their trade. The three applications provide several insights in terms of their usefulness at different steps of the policy cycle, their feasibility, their technical complexity (and thus the level of skill required) and also in terms of the primary users (from specialised analysts to a non-specialised audience).JRC.D.3-Land Resource
Chemosensory Event-Related Potentials and Power Spectrum could be A Possible Biomarker in 3M Syndrome Infants?
none10no3M syndrome is a rare disorder that involves the gene cullin-7 (CUL7). CUL7 modulates odour detection, conditions the olfactory response (OR) and plays a role in the development of the olfactory system. Despite this involvement, there are no direct studies on olfactory functional effects in 3M syndrome. The purpose of the present work was to analyse the cortical OR through chemosensory event-related potentials (CSERPs) and power spectra calculated by electroencephalogram (EEG) signals recorded in 3M infants: two twins (3M-N) and an additional subject (3M-O). The results suggest that olfactory processing is diversified. Comparison of N1 and Late Positive Component (LPC) indicated substantial differences in 3M syndrome that may be a consequence of a modified olfactory processing pattern. Moreover, the presence of delta rhythms in 3M-O and 3M-N clearly indicates their involvement with OR, since the delta rhythm is closely connected to chemosensory perception, in particular to olfactory perception.openInvitto, Sara; Grasso, Alberto; Lofrumento, Dario Domenico; Ciccarese, Vincenzo; Paladini, Angela; Paladini, Pasquale; Marulli, Raffaella; Pascalis, Vilfredo De; Polsinelli, Matteo; Placidi, GiuseppeInvitto, Sara; Grasso, Alberto; Lofrumento, Dario Domenico; Ciccarese, Vincenzo; Paladini, Angela; Paladini, Pasquale; Marulli, Raffaella; Pascalis, Vilfredo De; Polsinelli, Matteo; Placidi, Giusepp
Low-dose buprenorphine infusion to prevent postoperative hyperalgesia in patients undergoing major lung surgery and remifentanil infusion: a double-blind, randomized, active-controlled trial
Abstract Background Postoperative secondary hyperalgesia arises from central sensitization due to pain pathways facilitation and/or acute opioid exposure. The latter is also known as opioid-induced hyperalgesia (OIH). Remifentanil, a potent μ-opioid agonist, reportedly induces postoperative hyperalgesia and increases postoperative pain scores and opioid consumption. The pathophysiology underlying secondary hyperalgesia involves N-methyl-D-aspartate (NMDA)-mediated pain pathways. In this study, we investigated whether perioperatively infusing low-dose buprenorphine, an opioid with anti-NMDA activity, in patients receiving remifentanil infusion prevents postoperative secondary hyperalgesia. Methods Sixty-four patients, undergoing remifentanil infusion during general anaesthesia and major lung surgery, were randomly assigned to receive either buprenorphine i.v. infusion (25 μg h −1 for 24 h) or morphine (equianalgesic dose) perioperatively. The presence and extent of punctuate hyperalgesia were assessed one day postoperatively. Secondary outcome variables included postoperative pain scores, opioid consumption and postoperative neuropathic pain assessed one and three months postoperatively. Results A distinct area of hyperalgesia or allodynia around the surgical incision was found in more patients in the control group than in the treated group. Mean time from extubation to first morphine rescue dose was twice as long in the buprenorphine-treated group than in the morphine-treated group: 18 vs 9 min ( P =0.002). At 30 min postoperatively, patients receiving morphine had a higher hazard ratio for the first analgesic rescue dose than those treated with buprenorphine ( P =0.009). At three months, no differences between groups were noted. Conclusions Low-dose buprenorphine infusion prevents the development of secondary hyperalgesia around the surgical incision but shows no long-term efficacy at three months follow-up
L’utilizzo di tecnologie head-mounted display a supporto della didattica attraverso ambienti di apprendimento virtuali in contesti non formali
COM (International Council of Museum) defines a museum as a permanent institution in the service of society and its development, open to the public, which acquires, conserves, researches, communicates and exhibits the tangible and intangible heritage of humanity and its environment for the purposes of education, study and enjoyment. This statement seems to emphasize how a museum can be an education institution that embedded an educational project. Considering this (and reminding a progressive introduction of protocols and agreements between the Italian Ministry of Education, University and Research (MIUR) and national, regional as well as provincial museums), in 2015 the Department of Humanities, Philosophy and Education of the University of Salerno (DISUFF) and the Virtual Archaeological Museum of Herculaneum (MAV) signed a scientific cooperation agreement oriented to develop and implement methods, tools and inclusive educational technologies. The first project, of this cooperation, consists in the realization of an Edugame, usable through the virtual reality Oculus Rift technology (one of the types of headmounted display present on the market) set inside the MAV 3D model of Villa of the Papyri in Herculaneum. The game is realized to be explorative and interactive, that link the Italian archeological museums systems and didactic necessity to improve the teaching-learning process for the users of the Edugame. In this regard, the use of head-mounted display technologies, can offer a good support to teaching-learning process due to virtual learning environments in non-formal contexts.L’ICOM (International Council of Museum) definisce un museo un’istituzione permanente al servizio della società e del suo sviluppo, aperto al pubblico che acquisisce, conserva, ricerca, comunica ed espone ai fini dello studio. Questa affermazione sembra mettere in risalto come la didattica museale può essere considerata uno strumento di ricerca e di istruzione, incorporando al suo interno un progetto educativo. Sulla base di quanto esposto e in considerazione di una progressiva introduzione di protocolli d’intesa tra il Ministero dell’Istruzione, dell’Università e della Ricerca (MIUR) e musei nazionali, regionali e provinciali, nel 2015 il Dipartimento di Scienze Umane, Filosofiche e della Formazione dell’Università degli Studi di Salerno e il Museo Archeologico Virtuale (M.A.V.) hanno stipulato una convenzione di cooperazione scientifica orientata a sviluppare e implementare metodi, strumenti e tecnologie didattiche inclusive volte alla fruizione di alcune delle opere presenti nel M.A.V. Il progetto consistenella realizzazione di un Edugame, fruibile attraverso lo strumento di realtà virtuale Oculus Rift (una delle tipologie di head-mounted display presenti sul mercato), ambientato nella riproduzione 3D della “Villa dei Papiri” di Ercolano. Il gioco presenta un’architettura esplorativa, interattiva e didattica volta a fornireall’utenza un prodotto che garantisca una comunicazione tra il sistema museale e archeologico italiano e il processo di insegnamento-apprendimento garantendo un’esperienza didattica. In tal senso, l’utilizzo di tecnologie head-mounted display, possono offrire un valido supporto alla didattica grazie ad ambienti diapprendimento virtuali, in contesti non formali
Evidence for mitochondrial Lonp1 expression in the nucleus
The coordinated communication between the mitochondria and nucleus is essential for cellular activities. Nonetheless, the pathways involved in this crosstalk are scarcely understood. The protease Lonp1 was previously believed to be exclusively located in the mitochondria, with an important role in mitochondrial morphology, mtDNA maintenance, and cellular metabolism, in both normal and neoplastic cells. However, we recently detected Lonp1 in the nuclear, where as much as 22% of all cellular Lonp1 can be found. Nuclear localization is detectable under all conditions, but the amount is dependent on a response to heat shock (HS). Lonp1 in the nucleus interacts with heat shock factor 1 (HSF1) and modulates the HS response. These findings reveal a novel extramitochondrial function for Lonp1 in response to stress
