title: Informed consent in the Aotearoa New Zealand context

authors: Cargo, Tania

abstract: Psychologists are in very privileged positions; we use our clinical, community, academic, and research skills to support individuals, families, and communities, often during extremely vulnerable times in their lives. Psychologists have specific duties and responsibilities to not only offer a competent and ethical service, but to ensure that clients have been engaged in an open and honest process of gaining informed consent before a psychological service is offered, and either accepted or declined by the client (Knapp, Gottlieb, & Handelsman, 2015; Nagy, 2011).

title: Management of patients with early stage lung cancer - why do some patients not receive treatment with curative intent?

authors: Lawrenson, Ross

subjects: Lung cancer

abstract: BACKGROUNDS: This study aims to understand the factors that influence whether patients receive potentially curative treatment for early stage lung cancer. A key question was whether indigenous Māori patients were less likely to receive treatment. 
METHODS: Patients included those diagnosed with early stage lung cancer in 2011-2018 and resident in the New Zealand Midland Cancer Network region. Logistic regression model was used to estimate the odds ratios of having curative surgery/ treatment. The Kaplan Meier method was used to examine the all-cause survival and Cox proportional hazard model was used to estimate the hazard ratio of death. 
RESULTS: In total 419/583 (71.9%) of patients with Stage I and II disease were treated with curative intent - 272 (46.7%) patients had curative surgery. Patients not receiving potentially curative treatment were older, were less likely to have non-small cell lung cancer (NSCLC), had poorer lung function and were more likely to have an ECOG performance status of 2+. Current smokers were less likely to be treated with surgery and more likely to receive treatment with radiotherapy and chemotherapy. Those who were treated with surgery had a 2-year survival of 87.8% (95% CI: 83.8-91.8%) and 5-year survival of 69.6% (95% CI: 63.2-76.0%). Stereotactic ablative body radiotherapy (SABR) has equivalent effect on survival compared to curative surgery (hazard ratio: 0.77, 95% CI: 0.37-1.61). After adjustment we could find no difference in treatment and survival between Māori and non-Māori. 
CONCLUSIONS: The majority of patients with stage I and II lung cancer are managed with potentially curative treatment - mainly surgery and increasingly with SABR. The outcomes of those being diagnosed with stage I and II disease and receiving treatment is positive with 70% surviving 5 years.

title: Atomic components

authors: Reeves, Steve

subjects: computer science

abstract: There has been much interest in components that combine the best of state-based and event-based approaches. The interface of a component can be thought of as its specification and substituting components with the same interface cannot be observed by any user of the components. Here we will define the semantics of atomic components where both states and event can be part of the interface. The resulting semantics is very similar to that of (event only) processes. But it has two main novelties: one, it does not need recursion or unique fixed points to model nontermination; and two, the behaviour of divergence is modelled by abstraction, i.e. the construction of the observational semantics.
