Ribaut J, Leppla L, Teynor A, Valenta S, Dobbels F, Zullig LL, De Geest S. Theory-driven development of a medication adherence intervention delivered by eHealth and transplant team in allogeneic stem cell transplantation: the SMILe implementation science project. BMC Health Serv Res 2020; 20:827. [PMID: 32878623 PMCID: PMC7465386 DOI: 10.1186/s12913-020-05636-1] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2020] [Accepted: 08/09/2020] [Indexed: 01/21/2023] Open
Abstract
BACKGROUND Medication adherence to immunosuppressants in allogeneic stem cell transplantation (alloSCT) is essential to achieve favorable clinical outcomes (e.g. control of Graft-versus-Host Disease). Over 600 apps supporting medication adherence exist, yet they lack successful implementation and sustainable use likely because of lack of end-user involvement and theoretical underpinnings in their development and insufficient attention to implementation methods to support their use in real-life settings. Medication adherence has three phases: initiation, implementation and persistence. We report the theory-driven development of an intervention module to support medication adherence (implementation and persistence phase) in alloSCT outpatients as a first step for future digitization and implementation in clinical setting within the SMILe project (Development, implementation and testing of an integrated care model in allogeneic SteM cell transplantatIon faciLitated by eHealth). METHODS We applied Michie's Behavior Change Wheel (BCW) and the Capability-Opportunity-Motivation and Behavior (COM-B) model using three suggested stages followed by one stage added by our team regarding preparation for digitization of the intervention: (I) Defining the problem in behavioral terms; (II) Identifying intervention options; (III) Identifying content and implementation options; (IV) SMILe Care Model Prototype Development. Scientific evidence, data from a contextual analysis and patients'/caregivers' and clinical experts' inputs were compiled to work through these steps. RESULTS (I) Correct immunosuppressant taking and timing were defined as target behaviors. The intervention's focus was determined within the COM-B dimensions Capability (lack of knowledge, lack of routine), Opportunity (lack of cues, interruptions in daily routine) and Motivation (lack of problem solving, trivialization). (II) Five intervention functions were chosen, i.e. education, training, modelling, persuasion and enablement. (III) Twenty-four behavior change techniques were selected, e.g., goal setting, action planning and problem solving. (IV) Finally, seventeen user stories were developed to guide the SMILeApp's software development process. CONCLUSION Our example on the theory-driven development of an intervention module in alloSCT delivered by eHealth and transplant team using a rigorous 3 + 1-stage approach based on BCW, COM-B and agile software development techniques, can be used as methodological guidance for other eHealth intervention developers. Our approach has the potential to enhance successful implementation and sustained use of eHealth solutions in real-life settings.

Abstract
Purpose
– The purpose of this paper is to improve users’ search results relevancy by manipulating their explicit feedback.
Design/methodology/approach
– CoRRe – an explicit feedback model integrating three popular feedback, namely, Comment-Rating-Referral is proposed in this study. The model is further enhanced using case-based reasoning in retrieving the top-5 results. A search engine prototype was developed using Text REtrieval Conference as the document collection, and results were evaluated at three levels (i.e. top-5, 10 and 15). A user evaluation involving 28 students was administered, focussing on 20 queries.
Findings
– Both Mean Average Precision and Normalized Discounted Cumulative Gain results indicate CoRRe to have the highest retrieval precisions at all the three levels compared to the other feedback models. Furthermore, independent t-tests showed the precision differences to be significant. Rating was found to be the most popular technique among the participants, producing the best precision compared to referral and comments.
Research limitations/implications
– The findings suggest that search retrieval relevance can be significantly improved when users’ explicit feedback are integrated, therefore web-based systems should find ways to manipulate users’ feedback to provide better recommendations or search results to the users.
Originality/value
– The study is novel in the sense that users’ comment, rating and referral were taken into consideration to improve their overall search experience.

Bortezomib induces apoptosis by interacting with JAK/STAT pathway in K562 leukemic cells. Tumour Biol 2014; 35:7861-70. [PMID: 24824872 DOI: 10.1007/s13277-014-2048-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2014] [Accepted: 05/01/2014] [Indexed: 10/25/2022] Open
Abstract
In the current study, we aimed to identify the cytotoxic and apoptotic effects of bortezomib (BOR) on human K562 chronic myelogenous leukemia cells and to evaluate the potential roles of Janus kinase/signal transducers and activators of transcription (JAK/STAT) pathway members STAT3, STAT5, and JAK2 on BOR-induced cell death of leukemic cells. Cell viability was assessed via trypan blue dye exclusion test, and cytotoxicity of the BOR-treated cells was conducted by 2,3-bis(2-methoxy-4-nitro-5-sulphophenyl)-2H-tetrazolium-5-carboxanilide inner salt (XTT) assay. The relative messenger RNA (mRNA) expression levels of STAT3, STAT5A, STAT5B, and JAK2 were analyzed by quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR). On the other hand, their protein expression levels were detected by western blot method. The obtained results indicated that BOR treatment reduced cell viability and induced leukemic cell apoptosis in a dose- and time-dependent manner as compared to untreated control cells. While mRNA expression levels of STAT5A, STAT5B, and STAT3 were significantly reduced following BOR treatment when compared to untreated controls, it had no effect upon JAK2 mRNA expression. As for protein levels, STAT expressions were downregulated after BOR treatment especially at 72nd and 96th hours. Our results pointed out that BOR treatment had a significant potential of being an anticancer agent for chronic myelogenous leukemia therapy, and this effect could be due to the expressional downregulations of JAK/STAT pathway members.

Abstract
We report a rare case of haemorrhagic colitis attributed to dasatinib therapy in a 47-year-old African-American woman who was diagnosed with extramedullary T-lymphoblastic transformation of chronic myeloid leukaemia. The patient received intensive chemotherapy and dasatinib 100 mg/day. After achieving complete cytogenetic and major molecular response after 9 months of therapy, she developed bloody diarrhoea and pancytopenia. Colonoscopy showed inflammation of the descending colon and histopathology revealed patchy increase in intraepithelial lymphocytes. Dasatinib was stopped with prompt resolution of diarrhoea. The current literature suggests that there is an association in a subset of patients on dasatinib between clonal T-cell lymphocytosis in the peripheral blood and developing colitis and pleural effusions. These patients had a good response to dasatinib as did our patient. Our patient illustrates a unique disease presentation along with a rare drug adverse event.
