La colangiografía con fluorescencia fue más rápida de realizar, en unos pocos minutos (mediana 2 min (rango 0,5-5,0) versus 5 min (rango 5,2-17,6), P less then  0,001). CONCLUSIÓN Se confirmó que la colangiografía con fluorescencia no fue inferior a la colangiografía con rayos X para visualizar la unión crítica durante la colecistectomía laparoscópica.In addition to the best possible overall survival, discontinuation of the tyrosine kinase-inhibitor (TKI) treatment [treatment free remission (TFR)] without observing a recurrence of the disease has become a major goal of the therapy of chronic myelogenous leukemia (CML). Many clinical studies have demonstrated that TFR is possible, although for the moment limited to a fraction of the CML patients able to achieve a stable deep molecular response (DMR). The factors associated to the possibility of remaining in TFR or of losing it, have been investigated by a number of controlled and observation clinical trials and although total TKI treatment duration, DMR duration and stability and, more recently, also the depth of the molecular response obtained at the time of discontinuation have been shown to be significant elements, most of the factors associated with a higher possibility of a successful discontinuation still remain elusive and are here reviewed. © 2020 The Authors.

This systematic review aims to define the breadth and depth of PS/QI research dedicated to OHNS and to identify knowledge gaps as well as potential areas of future study. METHODS The study protocol was developed a priori using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) process. A computerized Ovid/Medline database search was conducted (January 1, 1965-September 30, 2019). Similar computerized searches were conducted using Cochrane Database, PubMed, and Google Scholar. Articles were classified by year, subspecialty, PS/QI category, Institute of Medicine (IOM) Crossing the Chasm categories, and World Health Organization (WHO) subclass. RESULTS Computerized searches yielded 11,570 eligible articles, 738 (6.4%) of which met otolaryngology PS/QI inclusion criteria; 178 (24.1%) were not specific to any one subspecialty. The most prevalent subspecialty foci were head and neck (29.9%), pediatric otolaryngology (16.9%), and otology/neurotology (11.0%). Studies examining complications or risk factors (32.0%) and outcomes/quality measures (16.3%) were the most common foci. Classification by the IOM included effective care (31.4%), safety (29.9%), and safety/effective care (25.3%). Most research fell into the WHO categories of understanding causes (28.5%) or measuring harm (28.3%). CONCLUSION Most OHNS PS/QI projects (32.0%) focus on reporting complications or risk factors, followed by outcomes/quality measures (16.3%). Deferoxamine Knowledges gaps for future research include healthcare disparities, multidisciplinary care, and the WHO category of studies translating evidence into safer care. LEVEL OF EVIDENCE NA Laryngoscope, 2020. © 2020 The American Laryngological, Rhinological and Otological Society, Inc.Asparaginase (ASNase) is an important anti-leukaemic drug in the treatment of childhood acute lymphoblastic leukaemia (ALL) and non-Hodgkin lymphoma (NHL). A substantial proportion of patients develop hypersensitivity reactions with anti-ASNase neutralising antibodies, resulting in allergic reactions or silent inactivation (SI), and characterised by inactivation and rapid clearance of ASNase. We report results of a prospective, real-time therapeutic drug monitoring of pegylated Escherichia coli (PEG-)ASNase and Erwinia ASNase in children treated for ALL and NHL in Belgium. Erwinia ASNase was given as second-line after hypersensitivity to PEG-ASNase. In total, 286 children were enrolled in the PEG-ASNase cohort. Allergy was seen in 11·2% and SI in 5·2% of patients. Of the 42 patients treated with Erwinia ASNase, 7·1% experienced allergy and 2·4% SI. The median trough PEG-ASNase activity was high in all patients without hypersensitivity. After Erwinia administration significantly more day 3 samples had activities less then 100 IU/l (62·5% vs. 10% at day 2 (D2)). The median D2 activity was significantly higher for intramuscular (IM; 347 IU/l) than for intravenous Erwinia administrations (159 IU/l). This prospective, multicentre study shows that monitoring of ASNase activity during treatment of children with ALL and NHL is feasible and informative. Treatment with Erwinia ASNase warrants close monitoring and optimally adherence to a 2-day interval of IM administrations. © 2020 British Society for Haematology and John Wiley & Sons Ltd.BACKGROUND Exhausted sugar beet pulp pellets (ESBPP), a sugar industry by-product generated after sugar extraction in the sugar production process, have been used as a raw material for lactic acid (LA) production via hydrolysis and fermentation by Lactobacillus casei. To design a more cost-effective process, simultaneous saccharification and fermentation (SSF) of ESBPP is proposed in the present study. The effects of pH control, nutrient supplementation and solid addition in fed-batch SSF on lactic acid production were investigated. RESULTS The highest LA concentration (26.88 g L-1 ) was reached in fed-batch SSF at a solid/liquid loading of 0.2 g mL-1 , with pH control (by adding 30 g L-1 CaCO3 to the medium) and nutrient supplementation (by adding 20 mL of MRS medium per 100 mL of buffer). Under these conditions, a maximum productivity of 0.63 g L-1 h-1 was achieved, which is 2.7 times higher than that attained in the control experiment (SSF inoculated at time 0 h). However, a slightly lower LA yield was obtained, revealing the need of an increasing dose of enzymes at high solid loading SSF. CONCLUSION An efficient fed-batch SSF strategy with pH control and MRS supplementation is described in the present study, attaining higher LA productivity compared to separate hydrolysis and fermentation and SSF. © 2020 Society of Chemical Industry. © 2020 Society of Chemical Industry.
