Psychological treatments and psychotherapies in the neurorehabilitation of pain. Evidences and recommendations from the italian consensus conference on pain in neurorehabilitation

BACKGROUND: It is increasingly recognized that treating pain is crucial for effective care within neurological rehabilitation in the setting of the neurological rehabilitation. The Italian Consensus Conference on Pain in Neurorehabilitation was constituted with the purpose identifying best practices for us in this context. Along with drug therapies and physical interventions, psychological treatments have been proven to be some of the most valuable tools that can be used within a multidisciplinary approach for fostering a reduction in pain intensity. However, there is a need to elucidate what forms of psychotherapy could be effectively matched with the specific pathologies that are typically addressed by neurorehabilitation teams. OBJECTIVES: To extensively assess the available evidence which supports the use of psychological therapies for pain reduction in neurological diseases. METHODS: A systematic review of the studies evaluating the effect of psychotherapies on pain intensity in neurological disorders was performed through an electronic search using PUBMED, EMBASE, and the Cochrane Database of Systematic Reviews. Based on the level of evidence of the included studies, recommendations were outlined separately for the different conditions. RESULTS: The literature search yielded 2352 results and the final database included 400 articles. The overall strength of the recommendations was medium/low. The different forms of psychological interventions, including Cognitive-Behavioral Therapy, cognitive or behavioral techniques, Mindfulness, hypnosis, Acceptance and Commitment Therapy (ACT), Brief Interpersonal Therapy, virtual reality interventions, various forms of biofeedback and mirror therapy were found to be effective for pain reduction in pathologies such as musculoskeletal pain, fibromyalgia, Complex Regional Pain Syndrome, Central Post-Stroke pain, Phantom Limb Pain, pain secondary to Spinal Cord Injury, multiple sclerosis and other debilitating syndromes, diabetic neuropathy, Medically Unexplained Symptoms, migraine and headache. CONCLUSIONS: Psychological interventions and psychotherapies are safe and effective treatments that can be used within an integrated approach for patients undergoing neurological rehabilitation for pain. The different interventions can be specifically selected depending on the disease being treated. A table of evidence and recommendations from the Italian Consensus Conference on Pain in Neurorehabilitation is also provided in the final part of the pape

Trichostatin A alters cytoskeleton and energy metabolism of pancreatic adenocarcinoma cells: an in depth proteomic study

Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal of all human cancers with a high mortality rate. Resistance to conventional treatments and chemotherapeutics is a typical feature of PDAC. To investigate the causes of drug resistance it is essential to deeply investigate the mechanism of action of chemotherapeutics. In this study, we performed an in depth shotgun proteomic approach using the label-free proteomic SWATH-MS analysis to investigate novel insights of the mechanism of action of the histone deacetylase (HDAC) inhibitor trichostatin A (TSA) in PDAC cells. This proteomic analysis in PaCa44 cells and data elaboration of TSA-regulated proteins by bioinformatics showed an overall up-regulation of cytokeratins and other proteins related to the cytoskeleton organization, keratinization, and apoptotic cell death. On the contrary, a large amount of the down-regulated proteins by TSA treatment belongs to the cellular energetic metabolism and to the machinery of protein synthesis, such as ribosomal proteins, determining synergistic cell growth inhibition by the combined treatment of TSA and the glycolytic inhibitor 2-deoxy-D-glucose in a panel of PDAC cell lines.

Integrated serum proteins and fatty acids analysis for putative biomarker discovery in inflammatory bowel disease

The diagnosis and management of Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), is still challenging. There is no definitive gold standard diagnostic test, which is made on patient history and with endoscopic and histological findings. This study analyzed serum proteins and fatty acids using mass spectrometry-based techniques. Quantitation of serum proteins was performed by depleting 14 high-abundance proteins, followed by tryptic digestion and LC-MS analysis, while fatty acids were analyzed using GC-MS. Bioinformatic tools were used to identify several new potential biomarkers for an early and non-invasive diagnosis of IBD, and to differentiate CD from UC. Moreover, the diagnostic power of the MS-identified biomarkers was also corroborated by Western Blot and ELISA assays. Hence, we identified the biological functions and pathways involved in the various subsets of IBD. Coagulation, fibrinolysis and acute phase response processes were found to be strongly involved in the condition. The involvement of several fatty acids, such as anti-inflammatory mediators, was also identified. Finally, proteomic and lipidomic data were integrated by using combinatorial and multivariate analyses to discover new combined biomarkers and to study the molecular pathways involved in IBD

New insights into the mechanism of action of the thienopyrimidine antitubercular prodrug TP053

The thienopyrimidine TP053 is an antitubercular prodrug active against both replicating and nonreplicating Mycobacterium tuberculosis (M. tuberculosis) cells, which requires activation by the mycothiol-dependent nitroreductase Mrx2. The investigation of the mechanism of action of TP053 revealed that Mrx2 releases nitric oxide from this drug both in the enzyme assays with purified Mrx2 and in mycobacterial cultures, which can explain its activity against nonreplicating bacilli, similar to pretomanid activated by the nitroreductase Ddn. In addition, we identified a highly reactive metabolite, 2-(4-mercapto-6-(methylamino)-2-phenylpyrimidin-5-yl)ethan-1-ol, which can contribute to the antimycobacterial effects on replicating cells as well as on nonreplicating cells. In summary, we explain the mechanism of action of TP053 on both replicating and nonreplicating M. tuberculosis and report a novel activity for Mrx2, which in addition to Ddn, represents another example of nitroreductase releasing nitric oxide from its substrate. These findings are particularly relevant in the context of drugs targeting nonreplicating M. tuberculosis, which is shown to be killed by increased levels of nitric oxide

DNA sequence and taxonomic gap analyses to quantify the coverage of aquatic cyanobacteria and eukaryotic microalgae in reference databases: Results of a survey in the Alpine region

30restrictedInternationalInternational coauthor/editorThe taxonomic identification of organisms based on the amplification of specific genetic markers (metabarcoding) implicitly requires adequate discriminatory information and taxonomic coverage of environmental DNA sequences in taxonomic databases. These requirements were quantitatively examined by comparing the determination of cyanobacteria and microalgae obtained by metabarcoding and lightmicroscopy. Weused planktic and biofilm samples collected in 37 lakes and 22 rivers across the Alpine region.We focused on two of the most used and best represented genetic markers in the reference databases, namely the 16S rRNA and 18S rRNA genes. A sequence gap analysis using blastn showed that, in the identity range of 99–100%, approximately 30% (plankton) and 60% (biofilm) of the sequences did not find any close counterpart in the reference databases (NCBI GenBank). Similarly, a taxonomic gap analysis showed that approximately 50% of the cyanobacterial and eukaryotic microalgal species identified by light microscopy were not represented in the reference databases. In both cases, themagnitude of the gaps differed between the major taxonomic groups. Even considering the species determined under the microscope and represented in the reference databases, 22% and 26% were still not included in the results obtained by the blastn at percentage levels of identity≥95% and≥97%, respectively. The main causes were the absence of matching sequences due to amplification and/or sequencing failure and potential misidentification in the microscopy step. Our results quantitatively demonstrated that in metabarcoding the main obstacles in the classification of 16S rRNA and 18S rRNA sequences and interpretation of high-throughput sequencing biomonitoring data were due to the existence of important gaps in the taxonomic completeness of the reference databases and the short length of reads. The study focused on the Alpine region, but the extent of the gaps could be much greater in other less investigated geographic areas.restrictedSalmaso, Nico; Vasselon, Valentin; Rimet, Frédéric; Vautier, Marine; Elersek, Tina; Boscaini, Adriano; Donati, Claudio; Moretto, Marco; Pindo, Massimo; Riccioni, Giulia; Stefani, Erika; Capelli, Camilla; Lepori, Fabio; Kurmayer, Rainer; Mischke, Ute; Klemenčič, Aleksandra Krivograd; Novak, Katarina; Greco, Claudia; Franzini, Giorgio; Fusato, Giampaolo; Giacomazzi, Federica; Lea, Alessia; Menegon, Silvia; Zampieri, Chiara; Macor, Arianna; Virgilio, Damiano; Zanut, Elisa; Zorza, Raffaella; Buzzi, Fabio; Domaizon, IsabelleSalmaso, N.; Vasselon, V.; Rimet, F.; Vautier, M.; Elersek, T.; Boscaini, A.; Donati, C.; Moretto, M.; Pindo, M.; Riccioni, G.; Stefani, E.; Capelli, C.; Lepori, F.; Kurmayer, R.; Mischke, U.; Klemenčič, A.K.; Novak, K.; Greco, C.; Franzini, G.; Fusato, G.; Giacomazzi, F.; Lea, A.; Menegon, S.; Zampieri, C.; Macor, A.; Virgilio, D.; Zanut, E.; Zorza, R.; Buzzi, F.; Domaizon, I
