La traiettoria evolutiva del mercato del lavoro italiano

Nel recente passato, il mercato del lavoro italiano ha sperimentato significativi mutamenti per ciò che concerne il grado e il modo di utilizzazione della forza lavoro, la produttività di quest’ultima, la qualità delle condizioni lavorative, le tipologie contrattuali utilizzate e la temperie delle relazioni industriali

Botulinum Toxin—A High-Dosage Effect on Functional Outcome and Spasticity-Related Pain in Subjects with Stroke

Stroke patients can develop spasticity and spasticity-related pain (SRP). These disorders are frequent and can contribute to functional limitations and disabling conditions. Many reports have suggested that higher doses than initially recommended of BTX-A can be used effectively and safely, especially in the case of severe spasticity; however, whether the treatment produces any benefit on the functional outcome and SRP is unclear. Studies published between January 1989 and December 2022 were retrieved from MEDLINE/PubMed, Embase, and Cochrane Central Register. Only obabotulinumtoxinA (obaBTX-A), onabotulinumtoxinA, (onaBTX-A), and incobotulinumtoxinA (incoBTX-A) were considered. The term “high dosage” indicates ≥600 U. Nine studies met the inclusion criteria. Globally, 460 subjects were treated with BTX-A high dose, and 301 suffered from stroke. Studies had variable method designs, sample sizes, and aims. Only five (55.5%) reported data about the functional outcome after BTX-A injection. Functional measures were also variable, and the improvement was observed predominantly in the disability assessment scale (DAS). SRP pain was quantified by visual analog scale (VAS) and only three studies reported the BTX-A effect. There is no scientific evidence that this therapeutic strategy unequivocally improves the functionality of the limbs. Although no clear-cut evidence emerges, certain patients with spasticity might obtain goal-oriented improvement from high-dose BTX-A. Likewise, data are insufficient to recommend high BTX dosage in SRP

ABO-mismatch adult living donor liver transplantation using antigen-specific immunoadsorption and quadruple immunosuppression without splenectomy

ABO-incompatible (ABO-I) liver transplantation is a controversial issue because of the generally less favorable outcome as compared to compatible transplants. Encouraging results have been shown by the introduction of new strategies to reduce posttransplant-specific hemagglutinin (HA) titers with plasmapheresis, reinforced immunosuppression (IS), and the use of splenectomy. We describe a new protocol consisting of daclizumab (DAC) induction, mycophenolate mofetil (MMF)/tacrolimus (TAC)/steroids without splenectomy. Five recipients (mean age of 47 +/- 14 yr) undergoing ABO-I living donor liver transplantation (LDLT) were included in this protocol. Immunoadsorbent columns (Glycosorb ABO) were used for antigen-specific immunoadsorption (ASI). The median follow-up was 18.5 +/- 10.5 months. ASI was very efficient in lowering HA titers (mean log, immunoglobulin [Ig] M [IgM] and IgG values before and after ASI were 5.9 +/- 2.8 and 1.2 +/- 1.4 [P = 0.0038] and 6.5 +/- 2.3 and 1.1 +/- 1.9, respectively [P = 0.0001]). Persisting low HA titers were observed over time. No sepsis nor cytomegalovirus infection episodes were recorded. Acute cellular rejection (ACR) occurred in 1 recipient responding to steroid pulse therapy. Two grafts were lost in 2 patients due to technical failure during the first postoperative month. We conclude that ASI using Glycosorb ABO, quadruple immunosuppression including DAC and MMF provide high efficiency to lower HA titers over time, avoiding the need for splenectomy. ABO-I LDLT can be performed with this adapted IS protocol

Effects of KEAP1 Silencing on the Regulation of NRF2 Activity in Neuroendocrine Lung Tumors

Background. The KEAP1/NRF2 pathway has been widely investigated in tumors since it was implicated in cancer cells survival and therapies resistance. In lung tumors the deregulation of this pathway is mainly related to point mutations of KEAP1 and NFE2L2 genes and KEAP1 promoter hypermethylation, but these two genes have been rarely investigated in low/intermediate grade neuroendocrine tumors of the lung. Methods. The effects of KEAP1 silencing on NRF2 activity was investigated in H720 and H727 carcinoid cell lines and results were compared with those obtained by molecular profiling of KEAP1 and NFE2L2 in a collection of 47 lung carcinoids. The correlation between methylation and transcript levels was assessed by 5-aza-dC treatment. Results. We demonstrated that in carcinoid cell lines, the KEAP1 silencing induces an upregulation of NRF2 and some of its targets and that there is a direct correlation between KEAP1 methylation and its mRNA levels. A KEAP1 hypermethylation and Loss of Heterozygosity at KEAP1 gene locus was also observed in nearly half of lung carcinoids. Conclusions. This is the first study that has described the effects of KEAP1 silencing on the regulation of NRF2 activity in lung carcinoids cells. The epigenetic deregulation of the KEAP1/NRF2 by a KEAP1 promoter hypermethylation system appears to be a frequent event in lung carcinoids
