Enhanced knowledge of the biological and genetic basis of cancer is re-defining target population for new treatments. In oncology, potential targets for a new therapeutic agent often include various solid and hematologic malignancies that share common signaling pathways. New agents are often tested in multiple tumor types across which information can be borrowed. We propose a hierarchical Bayesian design (HBD) to simultaneously test a novel agent in multiple groups for randomized phase II clinical trials with binary endpoints...

BACKGROUND: Difficult temperament in infancy is a risk factor for forms of later internalizing and externalizing psychopathology, including depression and anxiety. A better understanding of the roots of difficult temperament requires assessment of its early development with a genetically informative design. The goal of this study was to estimate genetic and environmental contributions to individual differences in infant negative emotionality, their persistence over time and their influences on stability between 5 and 18 months of age...

OBJECTIVE: We sought to characterize patterns of communication extrinsic to a decision aid that may impede goal-concordant care. BACKGROUND: Decision aids are designed to facilitate difficult clinical decisions by providing better treatment information. However, these interventions may not be sufficient to effectively reveal patient values and promote preference-aligned decisions for seriously ill, older adults. METHODS: We conducted a secondary analysis of 31 decision-making conversations between surgeons and frail, older inpatients with acute surgical problems at a single tertiary care hospital...

AIM: National and international healthcare agencies and organizations typically attribute slow or haphazard growth in hospice and palliative care in developing countries to various resource constraints. This study provides evidence of the substantial and widening gap between policy advocacy and individual decision-making concerning end-of-life care. It does so by establishing the incentives and risks that underlie choices of patients and providers against the relative scarcity of hospices in these countries...

BACKGROUND: One of the most distinctive management competencies is related to the ability to structure the strategic vision, develop long-term plans, and communicate them efficiently to the employees in order to empower them to enact. These managerial competencies in complex organizations are strongly related to the capacity to engage professionals as a predictor of high-performing organizations. PURPOSE: The aim of this study was to investigate the relationship between top management competencies, information sharing, and organizational performance in public health care system and to look at the management role in assuring information sharing on organizational strategies to achieve professionals' engagement...

PURPOSE/OBJECTIVE: Chemo-radiotherapy is an established primary curative treatment for anal cancer, but clinically equal rationale for different target doses exists. If joint preferences (physician and patient) are used to determine acceptable tradeoffs in radiotherapy treatment planning, multiple dose plans must be simultaneously explored. We quantified the degree to which different toxicity priorities might be incorporated into treatment plan selection, to elucidate the feasible decision space for shared decision making in anal cancer radiotherapy...

BACKGROUND: Consent remains a crucial, yet challenging, cornerstone of clinical practice. The ethical, legal and professional understandings of this construct have evolved away from a doctor-centred act to a patient-centred process that encompasses the patient's values, beliefs and goals. This alignment of consent with the philosophy of shared decision-making was affirmed in a recent high-profile Supreme Court ruling in England. The communication of information is central to this model of health care delivery but it can be difficult for doctors to gauge the information needs of the individual patient...

Nowadays many studies are being conducted to develop solutions for improving the performance of urban traffic networks. One of the main challenges is the necessary cooperation among different entities such as vehicles or infrastructure systems and how to exploit the information available through networks of sensors deployed as infrastructures for smart cities. In this work an algorithm for cooperative control of urban subsystems is proposed to provide a solution for mobility problems in cities. The interconnected traffic lights controller (TLC) network adapts traffic lights cycles, based on traffic and air pollution sensory information, in order to improve the performance of urban traffic networks...

Jan B Schmutz, Walter J Eppich
Health care teams are groups of highly skilled experts who may often form inexpert teams because of a lack of collective competence. Because teamwork and collaboration form the foundation of effective clinical practice, factors that promote collective competence demand exploration. The authors review team reflexivity (TR), a concept from psychology and management literatures, and how it could contribute to the collective competence of health care teams. TR captures a team's ability to reflect collectively on group objectives, strategies, goals, processes, and outcomes of past, current, and future performance to process key information and adapt accordingly...

Shiga toxin producing Escherichia coli (STEC) are important foodborne pathogens responsible for human illnesses. Cattle are a major reservoir that harbor the organism in the hindgut and shed in the feces. Shiga toxins (Stx) are the primary virulence factors associated with STEC illnesses. The two antigenically distinct Stx types, Stx1 and Stx2, encoded by stx1 and stx2 genes, share approximately 56% amino acid sequence identity. Genetic variants exist within Stx1 and Stx2 based on differences in amino acid composition and in cytotoxicity...

The mitogen-activated protein kinase (MAPK) cascade, which is a major signal transduction pathway widely distributed in eukaryotes, has an important function in plant development and stress responses. However, less information is known regarding the MAPKKK and MAPKK gene families in the important fruit crop banana. In this study, 10 MAPKK and 77 MAPKKK genes were identified in the banana genome, and were classified into 4 and 3 subfamilies respectively based on phylogenetic analysis. Majority of MAPKKK and MAPKK genes in the same subfamily shared similar gene structures and conserved motifs...

Species belonging to the Triatominae subfamily are commonly associated with Chagas disease, as they are potential vectors of the parasite Trypanosoma cruzi. However, their saliva contains a cocktail of diverse anti-hemostatic proteins that prevent blood coagulation, vasodilation and platelet aggregation of blood; components with indisputable therapeutic potential. We performed a transcriptomic and proteomic analyses of salivary glands and protein spots from 2DE gels of milked saliva, respectively, from the Mexican Triatoma pallidipennis...

BACKGROUND: A main element of patient-centred care, Patient Decision Aids (PtDAs) facilitate shared decision-making (SDM). A recent update of the International Patient Decision Aids Standards (IPDAS) emphasised patient involvement during PtDA development, but omitted a methodology for doing so. This article reports on the value of user-centred design (UCD) methods for the development of a PtDA that aims to support inflammatory arthritis patients in their choice between disease modifying anti-rheumatic drugs (DMARDs)...

REVIEW
Rudolf N Cardinal
BACKGROUND: Electronic medical records contain information of value for research, but contain identifiable and often highly sensitive confidential information. Patient-identifiable information cannot in general be shared outside clinical care teams without explicit consent, but anonymisation/de-identification allows research uses of clinical data without explicit consent. RESULTS: This article presents CRATE (Clinical Records Anonymisation and Text Extraction), an open-source software system with separable functions: (1) it anonymises or de-identifies arbitrary relational databases, with sensitivity and precision similar to previous comparable systems; (2) it uses public secure cryptographic methods to map patient identifiers to research identifiers (pseudonyms); (3) it connects relational databases to external tools for natural language processing; (4) it provides a web front end for research and administrative functions; and (5) it supports a specific model through which patients may consent to be contacted about research...
