Sept façons de faciliter le travail de l'équipe de chevet
Although classically considered a cornerstone of inpatient care, rounding at patients’ bedsides is increasingly being replaced by rounding in workrooms. Workroom rounds may provide a sense of efficiency and comfort, however bedside rounds have multiple benefits for patients, trainees and staff physicians. Alongside its benefits, there are human and institutional challenges when incorporating bedside rounding. This article aims to draw on our own experience of implementing bedside rounding at Kingston Health Sciences Centre, to guide staff physicians and institutions on how to implement bedside rounding effectively while overcoming its challenges. The following seven tips provide a framework to avoid pitfalls when implementing bedside team rounding on inpatient services.Bien que classiquement considéré comme la pierre angulaire des soins aux patients hospitalisés, les tournées médicales au chevet des patients sont de plus en plus remplacées par les tournées dans les salles d’enseignement.

31st Annual Meeting and Associated Programs of the Society for Immunotherapy of Cancer (SITC 2016) : part two
Background
The immunological escape of tumors represents one of the main ob- stacles to the treatment of malignancies. The blockade of PD-1 or CTLA-4 receptors represented a milestone in the history of immunotherapy. However, immune checkpoint inhibitors seem to be effective in specific cohorts of patients. It has been proposed that their efficacy relies on the presence of an immunological response. Thus, we hypothesized that disruption of the PD-L1/PD-1 axis would synergize with our oncolytic vaccine platform PeptiCRAd.
Methods
We used murine B16OVA in vivo tumor models and flow cytometry analysis to investigate the immunological background.
Results
First, we found that high-burden B16OVA tumors were refractory to combination immunotherapy. However, with a more aggressive schedule, tumors with a lower burden were more susceptible to the combination of PeptiCRAd and PD-L1 blockade. The therapy signifi- cantly increased the median survival of mice (Fig. 7). Interestingly, the reduced growth of contralaterally injected B16F10 cells sug- gested the presence of a long lasting immunological memory also against non-targeted antigens. Concerning the functional state of tumor infiltrating lymphocytes (TILs), we found that all the immune therapies would enhance the percentage of activated (PD-1pos TIM- 3neg) T lymphocytes and reduce the amount of exhausted (PD-1pos TIM-3pos) cells compared to placebo. As expected, we found that PeptiCRAd monotherapy could increase the number of antigen spe- cific CD8+ T cells compared to other treatments. However, only the combination with PD-L1 blockade could significantly increase the ra- tio between activated and exhausted pentamer positive cells (p= 0.0058), suggesting that by disrupting the PD-1/PD-L1 axis we could decrease the amount of dysfunctional antigen specific T cells. We ob- served that the anatomical location deeply influenced the state of CD4+ and CD8+ T lymphocytes. In fact, TIM-3 expression was in- creased by 2 fold on TILs compared to splenic and lymphoid T cells. In the CD8+ compartment, the expression of PD-1 on the surface seemed to be restricted to the tumor micro-environment, while CD4 + T cells had a high expression of PD-1 also in lymphoid organs. Interestingly, we found that the levels of PD-1 were significantly higher on CD8+ T cells than on CD4+ T cells into the tumor micro- environment (p < 0.0001).
Conclusions
In conclusion, we demonstrated that the efficacy of immune check- point inhibitors might be strongly enhanced by their combination with cancer vaccines. PeptiCRAd was able to increase the number of antigen-specific T cells and PD-L1 blockade prevented their exhaus- tion, resulting in long-lasting immunological memory and increased median survival
Parent and student views of multiage classrooms
This study examined the attitudes of 168 students and their parents in the first year of implementation of a primary level (ages 6–8) multiage program. Parents and students were surveyed in the fall and spring to determine their views on multiage versus same-age classrooms. Relationships between parent and students attitudes were also explored. Overall results indicate strong support for multiage classrooms with no statistically significant changes between fall and spring surveys. However, older students and their parents (both fall and spring) did express more negative opinions regarding academic progress. A relationship between parent and student attitudes was also evident but directionality could not be determined. Based on survey findings, school personnel considering multiage classrooms are encouraged to specifically address the needs and concerns of older students and their parents. The need for actively enlisting teachers in the promotion of the multiage concept (both with parents and students) is also addressed
