Initial experience of TAS-102 chemotherapy in Australian patients with Chemo-refractory metastatic colorectal cancer.

For patients with refractory metastatic colorectal cancer (mCRC) treatment with Trifluridine/Tipiracil, also known as TAS-102, improves overall survival. This study aims to investigate the efficacy and safety of TAS-102 in a real-world population from Victoria, Australia. A retrospective analysis of prospectively collected data from the Treatment of Recurrent and Advanced Colorectal Cancer (TRACC) registry was undertaken. The characteristics and outcomes of patients receiving TAS-102 were assessed and compared to those enrolled in the registration study (RECOURSE). Across 13 sites, 107 patients were treated with TAS-102. The median age was 60 years (range: 31-83), compared to 63 for RECOURSE. Comparing registry TAS-102-treated and RECOURSE patients, 75% vs 100% were ECOG performance status 0-1, 74% vs 79% had initiated treatment more than 18 months from diagnosis of metastatic disease and 36% vs 49% were RAS wild-type. Median time on treatment was 10.4 weeks (range: 1.7-32). Median progression-free survival (PFS) was 3.3 months compared to 2 months in RECOURSE, while median overall survival was the same at 7.1 months. Two patients (2.3%) had febrile neutropenia and there were no treatment-related deaths, where TAS-102 dose at treatment initiation was at clinician discretion.TRACC registry patients treated with TAS-102 were younger than those from the RECOURSE trial, with similar overall survival observed. Less strict application of RECIST criteria and less frequent imaging may have contributed to an apparently longer PFS.

Nursing staffs self-perceived outcome from a rehabilitation 24/7 educational programme - a mixed-methods study in stroke care.

BACKGROUND: During the past two decades, attempts have been made to describe nurses' contributions to the rehabilitation of inpatients following stroke. There is currently a lack of interventions that integrate the diversity of nurses' role and functions in stroke rehabilitation and explore their effect on patient outcomes. Using a systematic evidence- and theory-based design, we developed an educational programme, Rehabilitation 24/7, for nursing staff working in stroke rehabilitation aiming at two target behaviours; working systematically with a rehabilitative approach in all aspects of patient care and working deliberately and systematically with patients' goals. The aim of this study was to assess nursing staff members' self-perceived outcome related to their capability, opportunity and motivation to work with a rehabilitative approach after participating in the stroke Rehabilitation 24/7 educational programme. METHODS: A convergent mixed-method design was applied consisting of a survey and semi-structured interviews. Data collection was undertaken between February and June 2016. Data from the questionnaires (N = 33) distributed before and after the intervention were analysed using descriptive statistics and Wilcoxon sign rank test. The interviews (N = 10) were analysed using deductive content analysis. After analysing questionnaires and interviews separately, the results were merged in a side by side comparison presented in the discussion. RESULTS: The results from both the quantitative and qualitative analyses indicate that the educational programme shaped the target behaviours that we aimed to change by addressing the nursing staff's capability, opportunity and motivation and hence could strengthen the nursing staff's contribution to inpatient stroke rehabilitation. A number of behaviours changed significantly, and the qualitative results indicated that the staff experienced increased focus on their role and functions in rehabilitation practice. CONCLUSION: Our study provides an understanding of the outcome of the Rehabilitation 24/7 educational programme on nursing staff's behaviours. A mixed-methods approach provided extended knowledge of the changes in the nursing staff members' self-percived behaviours after the intervention. These changes suggest that educating the nursing staff on rehabilitation using the Rehabilitation 24/7 programme strengthened their knowledge and beliefs about rehabilitation, goal-setting as well as their role and functions.

Platinum-catalysed allylic alkylation: reactivity, enantioselectivity, and regioselectivity.

The use of platinum complexes as catalysts for allylic substitution has been studied. A variety of different complexes catalyse the reaction, and several substrates have been tested. In the alkylation of mono(alkyl)-substituted allylic acetates, regioselectivity is highly dependent on ligand choice. By using tricyclohexylphosphine as the ligand, almost complete formation of branched products is observed. The development of a highly enantioselective (ca. 80-90% ee) reaction that makes use of chiral diphenylphosphinooxazoline ligands (abbreviated as (S)-PN) is also described. The enantioselectivity is highly dependent on the ratio of ligand to platinum (when the ratio ligand/Pt is greater than 1:1, the ee drops off dramatically). This is in contrast to palladium and is interpreted in terms of differing coordination chemistry for the two metals ((S)-PN is hemilabile when complexed to platinum) and should be of significance to future systems that utilise heterobidentate ligands. The crystal structures of two isoelectronic platinum and palladium complexes [[(S)-PN]MCl2] are also described.
