Photosynthetic water oxidation: binding and activation of substrate waters for O–O bond formation
Authors: Vinyard David J. , Khan Sahr , Brudvig Gary W.
Published: June 2015

Photosynthetic water oxidation occurs at the oxygen-evolving complex (OEC) of Photosystem II (PSII). The OEC, which contains a Mn4CaO5inorganic cluster ligated by oxides, waters and amino-acid residues, cycles through five redox intermediates known as Sistates (i= 0–4). The electronic and structural properties of the transient S4intermediate that forms the O–O bond are not well understood. In order to gain insight into how water is activated for O–O bond formation in the S4intermediate, we have performed a detailed analysis of S-state dependent substrate water binding kinetics taking into consideration data from Mn coordination complexes. This analysis supports a model in which the substrate waters are both bound as terminal ligands and reactviaa water-nucleophile attack mechanism.
Nanoparticles and self-organisation: the emergence of hierarchical properties from the nanoparticle soup (i.e., the small is getting bigger). Concluding remarks for Faraday Discussion: Nanoparticle Synthesis and Assembly.
Authors: Schiffrin David J.
Published: June 2015

Some four years ago, one of the participants in this Discussion (Prof. Nicholas Kotov) predicted that: “within five years we shall see multiple examples of electronic, sensor, optical and other devices utilizing self-assembled superstructures” (N. A. Kotov, J. Mater. Chem., 2011, 21, 16673–16674). Although this prediction came partially to fruition, we have witnessed an unprecedented interest in the properties of materials at the nanoscale. The point highlighted by Kotov, however, was the importance of self-assembly of structures from well characterised building blocks to yield hierarchical structures, hopefully with predictable properties, a concept that is an everyday pursuit of synthetic chemists. This Discussion has brought together researchers from a wide range of disciplines, i.e., colloid science, modelling, nanoparticle synthesis and organisation, magnetic and optical materials, and new imaging methods, within the excellent traditional Faraday Discussion format, to discuss advances in areas relevant to the main theme of the meeting.

Objective This paper reports on the experiences and perspectives of community members in relation to advance healthcare directives and enduring power of attorney, including the factors that encourage or discourage engagement in advance care planning (ACP). Methods A qualitative methodology was used involving 26 in-depth telephone interviews with community members (mean age 66 years). The aims of the interview question were to gain an understanding of: (1) motivations for engaging in ACP; (2) barriers that prevent people from engaging in ACP; and (3) suggestions for promoting ACP. Results The findings suggest that: (1) community members lack knowledge about ACP; (2) forms appear inaccessible and complex; (3) community members avoid ACP due to fear, mistrust and concerns over control; and (4) there are misperceptions regarding the relevance of ACP based on age and health. Conclusions There is unnecessary fear, avoidance and mistrust around ACP activities, largely resulting from misinformation. There is an undoubted need for greater education and support to be offered to individuals and their families regarding ACP, its benefits and its limitations. What is known about the topic? There is a lack of awareness about ACP in Australia, which is compounded by issues in the accessibility of ACP information, forms and support in completing the often complex documentation. Further, studies have indicated health practitioners tend to avoid assisting patients with ACP decision making and formalisation of their wishes for health care should they lose testamentary capacity. What does this paper add? This paper contributes further understanding of the experiences and perceptions of people, particularly older Australians, in relation to ACP, including the motivating and discouraging factors for people in the uptake of advance healthcare directives and enduring power of attorney. People felt discomfort and mistrust about ACP, and lacked understanding of its relevance regardless of age or health status. Those who had engaged in ACP, prompted by family members or experiences in, or witnessing, ill health, felt a sense of security in having formalised their wishes. What are the implications for practitioners? It is now clear that people require improved provision of information and support around ACP-related activities. This support may best be offered by practitioners such as nurses and social workers who are knowledgeable regarding ACP and skilled in counselling. Without discussion of death and dying, and the role of ACP, people will continue to feel a mistrust and avoidance towards formalising their healthcare wishes in advance.
Associations between Australian clinical medical practitioner exposure to workplace aggression and workforce participation intentions
Authors: Hills Danny J.
Published: June 2015

Objective The aim of the present study was to determine the association between clinician exposure to workplace aggression from any source in the previous 12 months and workforce participation intentions. Methods A cross-sectional survey, in the third wave of the Medicine in Australia: Balancing Employment and Life (MABEL) study, was conducted between March 2010 and June 2011. Respondents were a representative sample of 9449 Australian general practitioners (GPs) and GP registrars (n = 3515), specialists (n = 3875), hospital non-specialists (n = 1171) and specialists in training (n = 888). Associations between aggression exposure and workforce participation intentions were determined using logistic regression modelling. Results In adjusted models, aggression exposure was positively associated with a greater likelihood of intending to reduce clinical workload in the next 5 years (odds ratio (OR) = 1.15, 95% confidence interval (CI) 1.02–1.29) and intending to leave patient care within 5 years (OR = 1.20, 95% CI 1.07–1.35). When also accounting for well being factors, aggression exposure remained positively associated with intending to leave patient care within 5 years (OR = 1.13, 95% CI 1.00–1.27). Conclusions Exposure to workplace aggression presents a risk to the retention of medical practitioners in clinical practice and a potential risk to community access to quality medical care. More concerted efforts in preventing and minimising workplace aggression in clinical medical practice are required. What is known about the topic? Very few studies have addressed the impact of workplace aggression on workforce participation intentions of medical practitioners. What does this paper add? This paper provides evidence that exposure to workplace aggression from any source is associated with intentions to reduce clinical workload or leave patient care. What are the implications for practitioners? There is a need to prevent or minimise the risk of exposure to workplace aggression from any source because the impacts may extend beyond the known psychological or physical effects to practitioner decisions about ongoing participation in the provision of clinical services.

Environmental context Volatile halogenated organic compounds (VOX) contribute to ozone depletion and global warming. Here we demonstrate that acidic salt lake sediments in Western Australia contribute to the global natural emission of these compounds and that the emissions are primarily of biotic origin. Elucidating major sources and sinks of VOX is a key task in environmental chemistry because their formation and degradation have major effects on atmospheric chemistry and thus earth climate. Abstract Volatile organohalogen compounds (VOX) are known environmental pollutants and contribute to stratospheric ozone depletion. Natural formation of VOX has been shown for many environments from the deep sea to forest soils and Antarctica. Recently, we showed that VOX are emitted from pH-neutral salt lakes in Western Australia and that they are mainly of biotic origin. To which extent this biotic organohalogen formation in salt lakes is pH-dependent and whether VOX are also formed under acidic conditions are unknown. Therefore, we quantified VOX emissions from an acidic salt lake in Western Australia (Lake Orr) in biotic and abiotic (γ ray-irradiated) microcosm experiments under controlled laboratory conditions. The experiments revealed that biotic halogenation processes also occurred under acidic conditions (pH range 3.8–4.8), though the emissions were approximately one order of magnitude lower (nanogram per kilogram dry sediment range) than from pH-neutral lake sediments. Among the detected substances were brominated, e.g. tribromomethane, as well as chlorinated compounds (e.g. trichloromethane). The addition of lactate and acetate, and ferrihydrite showed no stimulation of VOX formation in our microcosms. Hence, the stimulation of Fe-metabolising microorganisms and their potential effect on the formation of reactive Fe species did not promote VOX emissions, suggesting a direct enzymatic formation of the emitted compounds.
Dissolution of mixed amorphous–crystalline Cd-containing Fe coprecipitates in the presence of common organic ligands

Published: June 2015

Environmental context
Common soil minerals, which often contain trace metals in contaminated environments, are thought to limit metal-related risks in the environment. We studied the stability of these contaminated minerals and found that the presence of plant-derived organic compounds can alter contaminant availability in such environments. Understanding how soluble organics may change trace metal availability helps to predict risk and potentially remediate such environments more efficiently.

Abstract
Trace metals are common impurities in Fe oxides in soils and can be liberated by organic compounds in the soil. Impurities can also alter and potentially destabilise mineral structures by increasing amorphous or nanocrystalline components. Two Fe oxides found in smelter-contaminated soils, goethite (α-FeOOH) and franklinite (ZnFe2O4), were synthesised as coprecipitates with Cd and subjected to dissolution using oxalic acid, citric acid, cysteine and histidine. Substantial quantities of amorphous- (10–60% of total) and surface-associated Cd (5–70% of total) were present in all coprecipitates. Histidine and oxalic acid consistently enhanced, while cysteine inhibited, Cd release from all coprecipitated minerals. Mixed amorphous–crystalline mineral aggregations are common in natural soils, and must be further studied to understand their role in contaminant availability. In addition, Fe oxides, often considered sinks for toxic metals, may be less effective at reducing contaminant mobility and bioavailability in biologically active soils.
Relationship between otolith chemistry and age in a widespread pelagic teleost Arripis trutta: influence of adult movements on stock structure and implications for management

This study investigated how the stock structure of Arripis trutta is influenced by the movement of adult fish. Five-year-old fish were sampled from four regions in south-east Australia encompassing ~1500km of coastline. Transverse otolith sections were analysed using laser-ablation inductively coupled plasma-mass spectrometry, providing age-related elemental profiles. Multivariate analyses showed that for most age groups, the elemental fingerprint of northern New South Wales (NSW) fish was significantly different from those of the other locations. Northern NSW fish also had a different fingerprint from those of all other locations for the first part of the fish’s life. These results indicate that most A. trutta originate in southern NSW, Victoria and Tasmania and move progressively northward with increasing age. Some recruitment occurs in northern NSW but these fish may not mix with immigrants from further south until they are more than 5 years old. When assessed with the strong latitudinal age gradient of the population, these data are consistent with a single, panmictic stock. The data also highlight the utility of otolith transect analysis in understanding the influence of age-related movements on stock structure and appropriate spatial management of exploited fish species.
Risk of cardiovascular disease in HIV-positive Queensland men receiving combined antiretroviral therapy

Published: June 2015

Background
Cardiovascular disease (CVD) is a major cause of death among HIV-positive individuals receiving combination antiretroviral therapy (cART). The risk of CVD is estimated using a variety of risk calculations, however, currently there is no specific CVD risk calculator endorsed for Australians receiving cART. Methods: A retrospective study of 210 Queensland men older than 35 years with cART-treated HIV was conducted to estimate the prevalence of CVD and the risk of a cardiovascular event occurring within 5 years. The weighted Cohen’s kappa coefficient was used to estimate the agreement between the Australian Absolute CVD Risk Calculator and the Data Collection on Adverse Effects of Anti-HIV Drugs Study (D:A:D) 5-year Estimated CVD Risk Equation. Results: The prevalence of CVD was 31.9%. Hypertensive disease was the most prevalent CVD (25.2%). Queensland men with cART-treated HIV were at moderate risk (5%) of a cardiovascular event in the next 5 years. There was a substantial agreement (κ = 0.63) between the Australian Absolute CVD Risk Calculator and the D:A:D 5-year Estimated CVD Risk Equation. Conclusions: Queensland men with cART-treated HIV are experiencing high prevalence of CVD and are at moderate risk of a CVD event in the next 5 years. Primary care guidelines should emphasise CVD prevention as a keystone for the treatment of people living with HIV.

Background
The study evaluated acceptability, invitation letters and the test kit for a trial of human papillomavirus (HPV) self-sampling among never- and under-screened women in Australia. Methods: Victorian women, 30–69 years, who had never had a Pap test or were overdue for one, participated. Four focus groups including eight to nine participants segmented by age (30–49 and 50–69 years) and screening history (never- and under-screened) were conducted in August 2013. Discussions were recorded and transcribed verbatim and data analysed using thematic content analysis. Results: The response to the concept of HPV self-sampling was positive. Decision-making was largely influenced by the content of a pre-invitation letter. Appealing features of self-sampling were cost (free), convenience (home-based) and anticipated less discomfort (with a swab) than a Pap test. Small kits that fit in mailboxes were preferred over post office parcel collection. The perceived barriers include concerns about test accuracy and lack of confidence that a home-based test would give the same results as a physician administered test. Women wanted information on the timing of receipt of the results and information about the organisation providing the test. Conclusion: HPV self-sampling is a possible alternative for Australian women who are reluctant to have a Pap test and may increase the likelihood of participation in cervical cancer screening if women’s concerns about it can be addressed. The findings of this study are relevant for researchers, policymakers and practitioners implementing self-sampling for under-screened women as part of cervical screening programs.
