The toxicity and efficacy of intrathecal liposomal cytarabine (LC) were evaluated in children with central nervous system (CNS) relapsed/refractory acute leukemia/lymphoma. Thirty patients (male:female ratio 21:9; median age 9.4 years) with CNS relapsed/resistant disease were treated with intrathecal LC at dosages adjusted for age. Twenty-seven (90%) patients simultaneously received systemic chemotherapy, including concurrent high-dose cytarabine or methotrexate in 21 (70%) cases. Of 28 patients evaluable for response, 25 patients (89%) achieved CNS complete remission and three (11%) partial remission. The median number of intrathecal LC administrations per patient was 4. The cerebrospinal fluid was cleared after a median of 3 intrathecal LC administrations. Neurological toxicity ≥ grade 3 occurred in four (13%) patients. No permanent sequelae were observed. The median overall survival was 20.9 months and the 5-year probability of survival was 46%. These encouraging data suggest that intrathecal LC is well tolerated and effective in children with relapsed/refractory CNS leukemia/lymphoma.

Background: The Sound Training for Attention and Memory in Dementia (STAM-Dem) is a manualized music-based protocol designed to be used in the rehabilitation of cognitive functions in elderly patients with dementia (PWD). Method: This was a multicenter, single-blind, randomized, and controlled trial that involved 51 PWD. The objective was to test the STAM-Dem efficacy. Patients in the experimental group followed the STAM-Dem for 2 weekly sessions of 45 minutes for 12 weeks (in addition to standard care). Those in the control group continued with the normal “standard care” provided. Results: In the experimental group, the instruments immediate prose memory test (MPI), deferred prose memory test (MPD), attentional matrices, activities of daily living, Music Therapy Activity Scale (SVAM) and Geriatric Music Therapy Profile (GMP) increase significantly from pre to post-test ( P < .05). Conclusion: The protocol is feasible and data suggest that there was an effect on attentino (matrices) and prose memory skills (MPI and MPD). The effect size reveals a general improvement in the results of the experimental group.

An extensive literature has focused on the impact of new public management (NPM) oriented structural changes on academics’ practice and identity. These critical studies have been resolute in concluding that NPM inevitably leads to a degeneration of academics’ ethos and values. Drawing from the moral philosophy of Alasdair MacIntyre, we argue that these previous analyses have overlooked the moral agency of the academics and their role in ‘moralizing’ and consequently shaping the ethical nature of their practices. The paper provides a new theoretical understanding of NPM-oriented reforms in light of the virtue ethics approach, thereby directing the attention to the moral character and moral agency of academics. Our analysis of interviews collected in the business department of a Danish university provides an example of how individuals have divergent ethical understandings of these structural changes and enact/resist pre-defined social roles in different ways. While in some cases the NPM agenda of the institutions has triggered internal moral conflict and a crisis of moral character, in other cases the new logic resonates with academics’ values and evaluative standards. Partially departing from the theoretical ground of MacIntyre (1981), we conclude that academics can play a crucial role in shaping the morality of NPM-oriented institutions and in transforming these settings into suitable contexts for the cultivation of virtues.

ABSTRACTPeering decisions between Internet Service Providers (ISPs) contain substantial non‐measurable aspects requiring trust and informal cooperation among peering partners. We study whether virtual districts are observed between Internet peers. Our empirical analysis of the bilateral peering decisions at the Milan Internet Exchange confirms that these decisions are significantly influenced by: travel time either between ISPs' headquarters or towards the exchange—a proxy for distance, bandwidth—a proxy for size, and European connectivity. Proximity still plays a role in reducing the transaction costs of monitoring and punishing deviant behavior within an industry where trust is essential for Internet universal connectivity.

The study of the fermentation performance of Saccharomyces cerevisiae strains under high sugar stress during the vinification of partially dried grapes.Microvinification of partially dried grape must with sugar concentration of 35 degrees Brix was performed using four commercial strains to carry out alcoholic fermentation. A traditional red vinification without nutrients addition was applied. Yeasts displayed different efficiency to convert sugar in ethanol and varied in glycerol yield. Sugar consumption and ethanol level were attested at 80-87% and 143.5-158.0 g l(-1) respectively. High correlation between sugar and assimilable nitrogen consumption rate was observed. Statistical treatment of data by principal component analysis highlighted the different behaviours that strains exhibited in regard to the production of higher alcohols and other compounds important to wine quality.Saccharomyces cerevisiae strains displayed appreciable capability to overcome osmotic stress and to yield ethanol fermenting high sugar concentration grape must in winemaking condition.The results provided insights on the strain contribution to wine quality subordinate to stress condition. This investigation is of applicative interest for winemaking and processing industry that use high sugar concentration musts.
