RESUMO
INTRODUCTION: People living with mental health conditions (MH+) are more likely to smoke cigarettes than people without mental health conditions (MH-) and to experience tobacco-related disparities. The Tips From Former Smokers® (Tips®) campaign is a proven population-level strategy for motivating smokers to quit. In 2016, Tips included ads featuring Rebecca, a former smoker with depression. We evaluated self-reported frequency of exposure to the Rebecca and other Tips ads in association with quit intentions and quit attempts among MH+ and MH- smokers. METHODS: Intentions to quit and past 6-month quit attempts lasting at least 24 hours were reported from a two-wave longitudinal online survey conducted before and after the 2016 Tips campaign with a nationally representative sample of US adult cigarette smokers with (MH+, N = 777) and without (MH-, N = 1806) lifetime mental health conditions. RESULTS: In 2016, among MH+ respondents, greater exposure to the Rebecca ads was significantly associated with increased odds of intending to quit in the next 30 days (adjusted odds ratio [AOR] = 1.40, p < .05) and with reporting a quit attempt in the past 6 months (AOR = 1.25, p < .05). Among MH- respondents, greater exposure to the other Tips ads was associated with increased odds of making a quit attempt (AOR = 1.19, p < .05). CONCLUSIONS: Exposure to the Rebecca ads was associated with a greater likelihood of intentions to quit and quit attempts among MH+ smokers; whereas, exposure to the other (non-mental-health-related) Tips ads was associated with a greater likelihood of quit attempts among MH- smokers. IMPLICATIONS: National media campaigns are an important population-level strategy for reaching specific population groups who are experiencing tobacco-related disparities. The findings support the inclusion of ads featuring people living with mental health conditions in national tobacco education media campaigns, such as Tips.

Theory of change (ToC) is an approach widely used to guide planning, implementing, and evaluating change initiatives. While there is substantial guidance, there has been little attention on equity within ToC research and practice. We propose and illustrate the metaphor of 'knots' to frame practical and ethical challenges that arise when centering equity within ToC processes. Drawing on our experiences using a ToC approach in two case examples, we identify and illustrate five equity-related knots: (a) clarify root causes, pathways, and success; (b) facilitate participation across power and perspective differences; (c) integrate research evidence and practitioner knowledge; (d) represent complex change visually; and (e) creatively navigate constraints. We show why framing these as knots can help practitioners make wise judgments within the circumstances and close with recommendations for including knots in ToC processes, reporting, and guidance.

Evaluation must transform to center equity. Yet, while recent scholarship critiques evaluation at the macro level for reproducing societal inequities and calls the profession and individual evaluators to change, this research overlooks evaluation ecosystems - though dynamic interactions among evaluation teams, workplaces, community stakeholders, funders, and informal professional networks form crucial connections between the macro and micro levels and can be spaces for promoting equity within and through evaluations. Addressing this gap, this exploratory study proposes and uses an adapted socioecological framework to organize thematic analysis of data from interviews with evaluators in New England (n = 21) about factors that help and hinder equity-oriented evaluation practices. We identify nine domains and twenty-three factors across macro, meso, and micro levels that influence these evaluators' capacity to practice equity-oriented evaluation in regional, national, and international contexts. The study contributes a framework that future research can adapt to explore the relevance of identified domains and factors to other geographical settings. We also provide questions to guide evaluators, program leaders, and others in reflecting on leverage points for change within their own contexts and outline future directions for research on equity and evaluation.

Trastuzumab targets the human epidermal growth factor receptor 2 (HER2). Its overexpression occurs in 25% of breast cancers and is associated with aggressive tumor characteristics and poor prognosis in absence of targeted therapy. Trastuzumab dramatically improves HER2-positive breast cancer outcomes; however, its clinical use is associated with left ventricular dysfunction and heart failure. Patients receiving trastuzumab or other HER2-targeted therapies undergo routine cardiac function assessment. Holding and/or stopping trastuzumab treatment in the setting of left ventricular dysfunction is recommended. This article summarizes the role of trastuzumab in cancer treatment, the mechanisms of trastuzumab-induced cardiotoxicity, recent clinical investigations, and current controversies.

The authors developed a patient decision aid (PDA) to educate patients regarding CAD. Patients were randomized to standard of care or a PDA. PDA group had increased medical knowledge of CAD and decreased decisional conflict. Patients presenting in an outpatient setting with symptoms may benefit from the use of a PDA.

RESUMO
Diet composed of smaller particles can improve feed intake, digestibility, and animal growth or health, but in ruminant species can reduce rumination and buffering-the loss of which may inhibit fermentation and digestibility. However, the explicit effect of particle size on the rumen microbiota remains untested, despite their crucial role in digestion. We evaluated the effects of reduced particle size on rumen microbiota by feeding long-stem (loose) alfalfa hay compared to a ground and pelleted version of the same alfalfa in yearling sheep wethers during a two-week experimental period. In situ digestibility of the pelleted diet was greater at 48 h compared with loose hay; however, distribution of residual fecal particle sizes in sheep did not differ between the dietary treatments at any time point (day 7 or 14). Both average daily gain and feed efficiency were greater for the wethers consuming the pelleted diet. Observed bacterial richness was very low at the end of the adaptation period and increased over the course of the study, suggesting the rumen bacterial community was still in flux after two weeks of adaptation. The pelleted-hay diet group had a greater increase in bacterial richness, including common fibrolytic rumen inhabitants. The pelleted diet was positively associated with several Succiniclasticum, a Prevotella, and uncultured taxa in the Ruminococcaceae and Rickenellaceae families and Bacteroidales order. Pelleting an alfalfa hay diet for sheep does shift the rumen microbiome, though the interplay of diet particle size, retention and gastrointestinal transit time, microbial fermentative and hydrolytic activity, and host growth or health is still largely unexplored.

In the last twenty years, a conversation has emerged in the evaluation field about the potential of systems thinking and complexity science (STCS) to transform the practice of evaluating social interventions. Documenting and interpreting this conversation are necessary to advance our understanding of the significance of using STCS in planning, implementing, and evaluating social interventions. Guided by a generic framework for evaluation practice, this paper reports on an inter-disciplinary literature review and argues that STCS raises some new ways of thinking about and carrying out the following six activities: 1) supporting social problem solving; 2) framing interventions and contexts; 3) selecting and using methods; 4) engaging in valuing; 5) producing and justifying knowledge; and 6) facilitating use. Following a discussion of these issues, future directions for research and practice are suggested.

Coral spawning on the oceanic reef systems of north-western Australia was recently discovered during autumn and spring, but the degree to which species and particularly colonies participated in one or both of these spawnings was unknown. At the largest of the oceanic reef systems, the participation by colonies in the two discrete spawning events was investigated over three years in 13 species of Acropora corals (n = 1,855 colonies). Seven species spawned during both seasons; five only in autumn and one only in spring. The majority of tagged colonies (n = 218) spawned once a year in the same season, but five colonies from three species spawned during spring and autumn during a single year. Reproductive seasonality was not influenced by spatial variation in habitat conditions, or by Symbiodinium partners in the biannual spawner Acropora tenuis. Colonies of A. tenuis spawning during different seasons separated into two distinct yet cryptic groups, in a bayesian clustering analysis based on multiple microsatellite markers. These groups were associated with a major genetic divergence (G"ST = 0.469), despite evidence of mixed ancestry in a small proportion of individuals. Our results confirm that temporal reproductive isolation is a common feature of Acropora populations at Scott Reef and indicate that spawning season is a genetically determined trait in at least A. tenuis. This reproductive isolation may be punctuated occasionally by interbreeding between genetic groups following favourable environmental conditions, when autumn spawners undergo a second annual gametogenic cycle and spawn during spring.
