RESUMO
Schrenkiella parvula, a leading extremophyte model in Brassicaceae, can grow and complete its lifecycle under multiple environmental stresses, including high salinity. Yet, the key physiological and structural traits underlying its stress-adapted lifestyle are unknown along with trade-offs when surviving salt stress at the expense of growth and reproduction. We aimed to identify the influential adaptive trait responses that lead to stress-resilient and uncompromised growth across developmental stages when treated with salt at levels known to inhibit growth in Arabidopsis and most crops. Its resilient growth was promoted by traits that synergistically allowed primary root growth in seedlings, the expansion of xylem vessels across the root-shoot continuum, and a high capacity to maintain tissue water levels by developing thicker succulent leaves while enabling photosynthesis during salt stress. A successful transition from vegetative to reproductive phase was initiated by salt-induced early flowering, resulting in viable seeds. Self-fertilization in salt-induced early flowering was dependent upon filament elongation in flowers otherwise aborted in the absence of salt during comparable plant ages. The maintenance of leaf water status promoting growth, and early flowering to ensure reproductive success in a changing environment, were among the most influential traits that contributed to the extremophytic lifestyle of S. parvula.

BACKGROUND: Counseling to reduce access to lethal means such as firearms and medications is recommended for suicidal adults but does not routinely occur. We developed the Web-based Lock to Live (L2L) decision aid to help suicidal adults and their families choose options for safer home storage. OBJECTIVE: This study aimed to test the feasibility and acceptability of L2L among suicidal adults in emergency departments (EDs). METHODS: At 4 EDs, we enrolled participants (English-speaking, community-dwelling, suicidal adults) in a pilot randomized controlled trial. Participants were randomized in a 13:7 ratio to L2L or control (website with general suicide prevention information) groups and received a 1-week follow-up telephone call. RESULTS: Baseline characteristics were similar between the intervention (n=33) and control (n=16) groups. At baseline, many participants reported having access to firearms (33/49, 67%), medications (46/49, 94%), or both (29/49, 59%). Participants viewed L2L for a median of 6 min (IQR 4-10 min). L2L also had very high acceptability; almost all participants reported that they would recommend it to someone in the same situation, that the options felt realistic, and that L2L was respectful of values about firearms. In an exploratory analysis of this pilot trial, more participants in the L2L group reported reduced firearm access at follow-up, although the differences were not statistically significant. CONCLUSIONS: The L2L decision aid appears feasible and acceptable for use among adults with suicide risk and may be a useful adjunct to lethal means counseling and other suicide prevention interventions. Future large-scale studies are needed to determine the effect on home access to lethal means. TRIAL REGISTRATION: ClinicalTrials.gov NCT03478501; https://clinicaltrials.gov/ct2/show/NCT03478501.

OBJECTIVES: We sought to (1) clarify decision needs among suicidal adults with home firearm access; (2) identify accurate, unbiased and acceptable approaches for content and messaging; and (3) develop a tablet-delivered decision aid for firearm storage options. METHODS: Following international standards, we used stakeholder interviews to develop a decision aid for the decision, 'what option(s) to choose to reduce home access to firearms for an adult at risk of suicide'. Participants were adults with personal or family history of suicidal ideation or behaviours, firearm ownership or employment in a firearm range or store, involvement in suicide prevention field, or work as emergency department or other healthcare provider. RESULTS: Through 64 interviews, we created the 'Lock to Live' decision aid, which includes (1) introduction specifying the decision, (2) clarification of preferences and logistics, (3) table of storage options and (4) summary with specific next steps. The final tool had high user acceptability. CONCLUSIONS: Should the 'Lock to Live' decision aid prove useful in a pilot feasibility trial and subsequent testing, it could enhance lethal means counselling and help prevent firearm suicide.

A recommended component of suicide prevention is encouraging at-risk individuals to voluntarily and temporarily reduce access to firearms and other lethal methods. Yet delivering counseling on the topic can be difficult, given the political sensitivity of firearm discussions. To support such counseling, we sought to identify recommended framing and content of messages about reducing firearm access for suicide prevention. Through qualitative interviews with firearm owners and enthusiasts, we identified key points for use in framing (identity as a gun owner, trust, voluntary and temporary storage, and context and motivation) and specific content (preference for "firearm" over "gun," and legal issues such as background checks for transfers). These findings build on prior work and should enhance efforts to develop and deliver effective, acceptable counseling and-ultimately-prevent firearm suicide.

PURPOSE: Palliative radiation therapy (PRT) has an essential role in cancer symptom control but is underutilized in Ontario. This initiative aimed to implement an educational outreach intervention to improve knowledge of and access to PRT among interprofessional palliative health care teams across an Ontario Local Health Integration Network. METHODS AND MATERIALS: A needs assessment was completed from June to September 2018 with interprofessional palliative health care teams. Participants completed a survey to identify perceived opportunities, barriers, and enablers to recommending or referring patients for PRT. Thematic analysis informed content of the educational outreach intervention and included how to access PRT, common indications, case studies, and side-effect management after completing PRT. The educational outreach intervention was completed from October 2018 to January 2019. Participants completed a survey, and results were analyzed using descriptive statistics. The number of patients who received PRT was determined by cross-referencing the regional database with the radiation oncology information system. RESULTS: Although 22.9% of participants had previously recommended or referred patients, 96.2% of participants agreed or strongly agreed that they are likely to recommend or refer patients for PRT after the educational outreach intervention (n = 131). An increase was observed in the number of patients receiving PRT from the community during the intervention period. CONCLUSIONS: The educational outreach intervention improved knowledge and the likelihood of interprofessional palliative health care teams providing access to PRT for patients in the community. More patients now receive PRT, conveying improved symptom control and quality of life.

Introduction An important but often overlooked component of caring for cancer patients is survivorship care, provided after the completion of active treatment in order to facilitate transition into the next surveillance phase. A survivorship program was developed to deliver a one-on-one education session on healthy lifestyle behaviours and available resources to help patients transition to their post-treatment life. This study reports the outcome of this pilot survivorship care program provided to breast cancer patients completing radiation therapy. Program delivery format and content were evaluated for effectiveness, applicability, and feasibility. Methods and materials Between March 2017 and August 2018, 124 breast cancer patients, nearing completion of their curative intent radiation treatments, participated in this centre-specific survivorship program. The survivorship program entailed a one on one education session delivered to breast cancer patients within the last two weeks of their radiation treatment. Participants were provided a Microsoft PowerPoint presentation, information pamphlet, and evaluation form to provide feedback on materials and presentation. Survivorship education sessions were delivered by study staff or staff scheduled in the Pre-Radiotherapy Patient Assessment role. Follow-up phone calls were conducted post-session delivery to determine the ongoing applicability of survivorship material. Staff was also given an evaluation form upon completion of the trial to measure the session feasibility. Results Of the 124 participants in the study, 69 (56%) provided feedback. Results showed that 98% of participants felt the information provided either confirmed what they were already doing (44%) or encouraged them to consider a lifestyle change (54%). Additionally, 70% reported feeling more confident after completing the session. Staff survey results reported that 87.5% agreed or strongly agreed that these sessions were beneficial and valuable to patients Conclusions Delivering one-on-one education sessions to individual participants focusing on healthy lifestyle measures garnered a positive response from participants, increasing their confidence and knowledge for making lifestyle changes. While staff survey results pointed strongly in favour of continuing with the survivorship sessions, it was shown that the methods of delivery trialed in this study were not feasible to be implemented on a larger scale. With some workflow modification, implementing a survivorship care program in our cancer centre is a possible and important aspect of a patient's treatment journey.
RESUMO
Dramatic changes in the health system due to national health reform are raising important questions regarding the educational preparation of social workers for the new health arena. While dual-degree programs in public health and social work can be an important response to what is needed educationally, little is known about them. The National MSW/MPH Programs Study surveyed MSW/MPH program administrators to better understand the prevalence, models, structure, and challenges of these dual-degree programs. Forty-two programs were identified, and 97.6% of those contacted participated (n=41). Findings indicate that MSW/MPH programs are popular, increasing, geographically dispersed, and drawing talented students interested in trans-disciplinary public health social work practice. Challenges for these programs include the need for greater institutional support, particularly funding, and a general lack of best practices for MSW/MPH education. While findings from this study suggest graduates appear especially well-prepared for leadership and practice in the new health environment, additional research is needed to assess their particular contributions and career trajectories.
RESUMO
Staphylococcus aureus can be carried on the skin and nasal passages of humans and animals as a commensal. A case of human methicillin-resistant S. aureus infection resulting from contact with pork has been reported. Poultry carcasses are sold at retail with the skin intact, but pork and beef typically are not. Thus, the risk of methicillin-resistant S. aureus human infection from whole raw poultry carcasses may be greater than that of exposure from pork or beef. The objective of this study was to isolate and characterize S. aureus from whole retail poultry carcasses and compare the isolates to S. aureus isolates from humans. A total of 25 S. aureus isolates were collected from 222 whole poultry carcasses. The isolates were characterized phenotypically with antibiotic resistance disc diffusion assays and genotypically using multilocus sequence typing. A total of 17 S. aureus isolates obtained from healthy humans were included and characterized in the same way as the poultry isolates. Staphylococcus spp. were recovered from all poultry carcasses. Only 25 poultry carcasses (11.2%) were contaminated with S. aureus. Of these 25 isolates, 36% were resistant to at least one of the antibiotics tested and 20% were resistant to two or more antibiotics tested. However, 100% of the human isolates were resistant to at least one of the antibiotics and 94% were resistant to two or more antibiotics. The results of the multilocus sequence typing indicate that most of the isolates grouped according to source. These results indicate a low prevalence of S. aureus present in poultry, and the isolates were not phenotypically similar to human isolates. The low number of S. aureus isolates from this study indicates that chicken carcasses would appear to not be a significant source of this bacterium.

UNLABELLED: In order to address the growing demand for more natural poultry products, alkaline phosphates commonly used in chicken breast meat marinades were replaced with plum ingredients and evaluated. For initial sensory evaluation, 200 consumers of chicken were served a small portion of the chicken breast on a plate and were asked to evaluate the product for overall impression, flavor, and texture on a 9-point hedonic scale with 1 = "dislike extremely" and 9 = "like extremely." Also, a 5-point just-about-right (JAR) scale was used on questions about tenderness, juiciness, overall flavor, and saltiness. Both hedonic and JAR demonstrated that the marinades of plum concentrate and the blend of plum fiber and powder were not distinguishable from the control (P > 0.05). Using two different percentages of fiber/powder blend, two different percentages of concentrate, sodium tripolyphosphate (STPP), and no marinade, measurements were made for marinade per cent pickup, thaw loss, and cook loss. Plum concentrate at 1.1% was most similar to STPP in marinade per cent pickup, thaw loss, drip loss, and cook loss. These results show that plum ingredients can potentially be used as a substitute in standard phosphate marinades. PRACTICAL APPLICATION: Consumers are increasingly demanding more natural foods with less artificial additives. This research presents the results of experiments using dried plum ingredients as a substitute for phosphates commonly used in marinades for chicken. Results indicate that dried plum ingredients may be a suitable substitute for phosphates in marinades.

BACKGROUND: Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis has been observed in adults and children with mood and anxiety disorders and is thought to be involved in the pathogenesis of these disorders. We recently studied a diverse community sample of boys and found associations of behavioral problems, including symptoms of depression and anxiety, with basal and stress-induced cortisol concentrations. Here we examine cortisol-emotional/behavioral associations at a two-year follow-up and test whether initial cortisol is predictive of worsening emotional/behavioral problems two years later. METHOD: Seventy-eight 10-14-year-old boys and their mothers completed a battery of psychosocial assessments, provided morning and afternoon saliva samples, and participated in a home visit involving mildly stressful tasks and saliva collection for cortisol assay during a two-year follow-up assessment. RESULTS: Consistent with the findings from our time 1 assessment, greater declines in cortisol across the home-visit challenge task were significantly associated with internalizing and externalizing behaviors as well as attention problems and social problems at the two-year follow-up. In addition, morning and afternoon cortisol concentrations at the initial assessment were significant positive predictors of the later development of child depressive symptoms at follow-up after controlling for initial depressive symptoms. CONCLUSION: These findings demonstrate that children in the community with internalizing and externalizing behavior problems have altered patterns of HPA axis stress reactivity. In addition, our prospective findings suggest that elevated cortisol concentrations may influence the later development of emotional/behavioral problems in boys.
