RESUMO
ISSUE ADDRESSED: Health information can be easily and cheaply provided through the Internet. However, we do not know whether older adults, those people most likely to be living with a chronic disease, are online or whether they use the Internet to find health information. METHODS: In order to establish the proportion of older Australians online, the impact of their current health status and chronic disease diagnosis on Internet usage and whether they use the Internet to search for health information, a paper-based survey was developed and mailed to 9000 older adults, resident in New South Wales, Australia (response rate = 46.8% ). RESULTS: Results showed that many older Australians are online (52.3%) and that the majority who are use the Internet to find health information (68.5%). Respondents were more likely to use the Internet if they reported good health. The presence of most chronic diseases reduced use of the Internet; however, this was not the case for those reporting asthma, anxiety or sleep apnoea. Internet use decreased as the number of reported co-morbidities increased. However, once online, self-perceived overall health and number of chronic diseases did not affect use of the Internet to find health information. CONCLUSIONS: This study is important as there is currently little information available about Internet use for health information by older Australians. Findings show that the provision of health information online has the potential to reinforce existing barriers created by the social determinants of health. SO WHAT?: There is a role for the Internet in providing preventative, health promotion information, to older adults, who are already online and younger, computer literate audiences. However, practitioners need to consider the fact that this mode of delivery reinforces existing social divides; requires people to have Internet access and be both literate and e-literate.

The combination of economic and social costs associated with non-communicable diseases provide a compelling argument for developing strategies that can influence modifiable risk factors, such as discrete food choices. Models of behaviour, such as the Theory of Planned Behaviour (TPB) provide conceptual order that allows program designers and policy makers to identify the substantive elements that drive behaviour and design effective interventions. The primary aim of the current review was to examine the association between TPB variables and discrete food choice behaviours. A systematic literature search was conducted to identify relevant studies. Calculation of the pooled mean effect size (r(+)) was conducted using inverse-variance weighted, random effects meta-analysis. Heterogeneity across studies was assessed using the Q- and I(2)-statistics. Meta-regression was used to test the impact of moderator variables: type of food choice behaviour; participants' age and gender. A total of 42 journal articles and four unpublished dissertations met the inclusion criteria. TPB variables were found to have medium to large associations with both intention and behaviour. Attitudes had the strongest association with intention (r(+) = 0.54) followed by perceived behavioural control (PBC, r(+) = 0.42) and subjective norm (SN, r(+) = 0.37). The association between intention and behaviour was r(+) = 0.45 and between PBC and behaviour was r(+) = 0.27. Moderator analyses revealed the complex nature of dietary behaviour and the factors that underpin individual food choices. Significantly higher PBC-behaviour associations were found for choosing health compromising compared to health promoting foods. Significantly higher intention-behaviour and PBC-behaviour associations were found for choosing health promoting foods compared to avoiding health compromising foods. Participant characteristics were also found to moderate associations within the model. Higher intention-behaviour associations were found for older, compared to younger age groups. The variability in the association of the TPB with different food choice behaviours uncovered by the moderator analyses strongly suggest that researchers should carefully consider the nature of the behaviour being exhibited prior to selecting a theory.

AIM: To synthesise primary research exploring decision making practices used to determine the time to retire from driving for individuals living with a dementia. BACKGROUND: Driving requires complex cognitive and physical skills potentially compromised due to the progressive nature of dementia. Whilst on-road assessments are considered reliable indicators of driving capacity by clinicians, drivers with dementia disagree. DESIGN: Integrative literature review informed by Whittemore & Knafl (2005). DATA SOURCES: Electronic database search of Medline, CINAHL, Web of Science, Google Scholar 1997-2012; and incremental hand search. REVIEW METHODS: Primary studies published in peer reviewed journals were appraised against quality assessment criteria using CASP methodological assessment tools. RESULTS: A total of 43 studies were retained for synthesis. Key findings were abstracted and a themes matrix was generated to identify patterns of meaning. Six themes emerged: (i) dementia may compromise the complex task of driving; (ii) defining onset and severity of dementia is problematic; (iii) symptom progression impacts on driving skills; (iv) assessment of fitness to drive remains subjective; (v) some drivers are reluctant to accept negative assessment outcomes; and (vi) the search for effective strategies to enhance acceptance of driver retirement continues. CONCLUSION: This integrative literature review identified a large body of knowledge exploring the issues of driving cessation for drivers with dementia. However a challenge remains for practitioners, drivers and their family carers regarding how best to address this highly emotive issue. Findings could inform a structured approach to address this sensitive topic in a timely manner.

BACKGROUND: A competitive Carrick Institute Competitive Grant (CG7-523) was obtained to explore what skills were taught and what assessment of practice approaches were used in nursing programmes in Australia. The intention was twofold; firstly to identify what skills were being taught which would contribute to the development of an assessment of practice toolkit for eligibility to practice programmes in Australia. This paper specifically reports on the skills taught in nursing programmes in Australia. METHODS: A qualitative research methodology was used through a documentary analysis of university curriculum documents. This was undertaken independently by two researchers; the data was then reviewed by an expert group. The skills taught were explored, listed and categorised using a conceptual framework, then refined and reported. RESULTS: Over 1300 skills were initially identified within nursing programmes across Australia; these were 'clustered' using a framework into 30 skills areas. These included psychomotor skills to skills areas that relate to human factors such as communication, team work, leadership and supervision. CONCLUSIONS: A wide range of skills were referred to in university nursing programme curriculae in Australia. There were some significant variations; some universities taught their student nurses how to manage a client/patient requiring external invasive ventilator support. There were however a number of similar skills areas identified; such as acute care assessment skills (monitoring vital signs) and mental health assessment skills. The range of skills taught within nursing curriculum is challenging as there is only limited time to expose students to those skills and afford the student the opportunity to practice those skills in order to achieve competence prior to registration.
RESUMO
With the advancement in technology and availability of the Internet, online health education could become one of the media for health education. As health education is to persuade patients on health behavioural change, understanding perceived benefits of online health education is an important aspect to explore. The aim of this study is to explore consumers and health professionals opinion on online health education. Literature review was conducted and identified the benefits of online health education (OHE). Survey was conducted to health consumers and health professionals. Descriptive analyses were performed using SPSS Version 19.0. The analysis of the literature has identified a set of 12 potential benefits of OHE which had been used to understand the perceptions of the effectiveness of OPE sites and these have been validated in the study. This study has the practical implication as the study identified OHE effectiveness, which definitely can assist health practitioners on health education, which can lead to better health outcome.

PURPOSE: Physical symptoms associated with breast cancer and its treatment can substantially interfere with functional outcomes and quality of life. The present study seeks to delineate the relationship between physical symptom burden and cancer-related goal interference in early-stage breast cancer patients. METHODS: Self-report questionnaires were administered to 43 eligible female patients at four time-points in the 6 months following surgery for early-stage breast cancer. Physical symptoms, cancer-related goal interference, and psychological distress were assessed at each time-point. K-means cluster analysis and independent sample t tests evaluated the relationships of interest. RESULTS: Women with a higher physical symptom burden experienced significantly higher goal interference and psychological distress than those with a lower burden at multiple time-points following surgery. CONCLUSIONS: This study provides preliminary evidence that physical symptom burden can interfere with important goal pursuit in early-stage breast cancer patients. Breast cancer survivors with ongoing challenging symptoms may require targeted psychosocial support to cope with possible goal interference and associated distress.

AIM: To examine the bidirectional relationship between short sleep duration and body mass index (BMI). A secondary aim was to investigate whether reduced physical activity and increased screen time (television and computer use) mediated these associations. METHODS: This study utilised data from the Longitudinal Study of Australian Children, which is an observational cohort study of Australian children. The sample included 2984 (52.4% boys) children followed from 4 to 5 years of age until 8 to 9 years of age. Sleep duration, screen time and covariates were reported by parents, with BMI measured objectively. Cross-lagged modelling investigated the bidirectional association between sleep duration and BMI; lagged panel mediation modelling examined physical activity and screen time as potential mediators. RESULTS: Short sleep duration at 4 to 5 years of age was significantly associated with higher BMI at 8 to 9 years of age (ß= -.07, p = .044). The relationship between short sleep duration at 4 to 5 years of age and higher BMI at 8 to 9 years of age was partially mediated by increased television viewing at 6 to 7 years of age (ß = -.01, 95% confidence interval [-.02, -.002]). CONCLUSION: Short sleep duration could be a risk factor for obesity in children. Increased television viewing may be one mechanism underlying this longitudinal relationship.

BACKGROUND: GP training in Australia can be professionally isolating, with trainees spread across large geographic areas, leading to problems with rural workforce retention. Virtual communities of practice (VCoPs) may provide a way of improving knowledge sharing and thus reducing professional isolation. OBJECTIVE: The goal of our study was to review the usefulness of a 7-step framework for implementing a VCoP for general practitioner (GP) training and then evaluated the usefulness of the resulting VCoP in facilitating knowledge sharing and reducing professional isolation. METHODS: The case was set in an Australian general practice training region involving 55 first-term trainees (GPT1s), from January to July 2012. ConnectGPR was a secure, online community site that included standard community options such as discussion forums, blogs, newsletter broadcasts, webchats, and photo sharing. A mixed-methods case study methodology was used. Results are presented and interpreted for each step of the VCoP 7-step framework and then in terms of the outcomes of knowledge sharing and overcoming isolation. RESULTS: Step 1, Facilitation: Regular, personal facilitation by a group of GP trainers with a co-ordinating facilitator was an important factor in the success of ConnectGPR. Step 2, Champion and Support: Leadership and stakeholder engagement were vital. Further benefits are possible if the site is recognized as contributing to training time. Step 3, Clear Goals: Clear goals of facilitating knowledge sharing and improving connectedness helped to keep the site discussions focused. Step 4, A Broad Church: The ConnectGPR community was too narrow, focusing only on first-term trainees (GPT1s). Ideally there should be more involvement of senior trainees, trainers, and specialists. Step 5, A Supportive Environment: Facilitators maintained community standards and encouraged participation. Step 6, Measurement Benchmarking and Feedback: Site activity was primarily driven by centrally generated newsletter feedback. Viewing comments by other participants helped users benchmark their own knowledge, particularly around applying guidelines. Step 7, Technology and Community: All the community tools were useful, but chat was limited and users suggested webinars in future. A larger user base and more training may also be helpful. Time is a common barrier. Trust can be built online, which may have benefit for trainees that cannot attend face-to-face workshops. Knowledge sharing and isolation outcomes: 28/34 (82%) of the eligible GPT1s enrolled on ConnectGPR. Trainees shared knowledge through online chat, forums, and shared photos. In terms of knowledge needs, GPT1s rated their need for cardiovascular knowledge more highly than supervisors. Isolation was a common theme among interview respondents, and ConnectGPR users felt more supported in their general practice (13/14, 92.9%). CONCLUSIONS: The 7-step framework for implementation of an online community was useful. Overcoming isolation and improving connectedness through an online knowledge sharing community shows promise in GP training. Time and technology are barriers that may be overcome by training, technology, and valuable content. In a VCoP, trust can be built online. This has implications for course delivery, particularly in regional areas. VCoPs may also have a specific role assisting overseas trained doctors to interpret their medical knowledge in a new context.

BACKGROUND: An increasing number of older adults drive automobiles. Given that the prevalence of dementia is rising, it is necessary to address the issue of driving retirement. The purpose of this study is to evaluate how a self-administered decision aid contributed to decision making about driving retirement by individuals living with dementia. The primary outcome measure in this study was decisional conflict. Knowledge, decision, satisfaction with decision, booklet use and booklet acceptability were the secondary outcome measures. METHODS: A mixed methods approach was adopted. Drivers with dementia were recruited from an Aged Care clinic and a Primary Care center in NSW, Australia. Telephone surveys were conducted before and after participants read the decision aid. RESULTS: Twelve participants were recruited (mean age 75, SD 6.7). The primary outcome measure, decisional conflict, improved following use of the decision aid. Most participants felt that the decision aid: (i) was balanced; (ii) presented information well; and (iii) helped them decide about driving. In addition, mean knowledge scores improved after booklet use. CONCLUSIONS: This decision aid shows promise as an acceptable, useful and low-cost tool for drivers with dementia. A self-administered decision aid can be used to assist individuals with dementia decide about driving retirement. A randomized controlled trial is underway to evaluate the effectiveness of the tool.

BACKGROUND: Populations are ageing and therefore non-communicable diseases are becoming leading causes of global morbidity, which need to be the focus of primary care services and training. Some older patients are uncomfortable with general practitioner (GP) trainees managing their chronic conditions, reducing clinical experience opportunities for trainees. This Australian cross-sectional study explored the factors underlying patients' attitudes to trainees in an agency theory framework. METHODS: Fifty patients aged 60 and over from each of 38 training practices were offered a questionnaire after their consultation. Principal component analysis of the results was undertaken. Factor scores were calculated. Binary logistic modelling was used to identify relationships between participant characteristics, behaviours, attitude items and factor scores. RESULTS: The response rate was 47.9% (n = 911). Three factors were identified: 'Interpersonal Trust' (IPT); 'Institution/system Trust' (ST); and 'Interpersonal Continuity' (IPC). Lower self-rated health (SRH) was associated with higher IPT factor scores (P = 0.023); higher SRH with higher ST scores (P = 0.001); and chronic illness with higher IPC scores (P = 0.005). Higher ST scores were associated with greater comfort with trainees' involvement in chronic care (P < 0.001) and frequency of trainee visits (P < 0.001), while higher IPC scores were negatively associated (P < 0.001 and P = 0.003, respectively). High IPT scores were associated with lower satisfaction with trainee visits (P = 0.001). DISCUSSION: These results indicate that better SRH, via higher institution/ST, is associated with favourable attitudes and attendance with trainees. In addition, chronic illness, via a higher need for IPC, is associated with lower comfort and attendance. These findings are consistent with agency theory, which shows potential as a framework for future interventions and research into older patient-trainee interactions.

Web 2.0 experts working in social marketing participated in qualitative in-depth interviews. The research aimed to document the current state of Web 2.0 practice. Perceived strengths (such as the viral nature of Web 2.0) and weaknesses (such as the time consuming effort it took to learn new Web 2.0 platforms) existed when using Web 2.0 platforms for campaigns. Lessons learned were identified--namely, suggestions for engaging in specific types of content creation strategies (such as plain language and transparent communication practices). Findings present originality and value to practitioners working in social marketing who want to effectively use Web 2.0.

OBJECTIVES: The aim of this study was to establish the feasibility and acceptability of an online asthma self-management program developed for older Australians with asthma. METHODS: AsthmaWise, an internet education self-management program, was piloted for a 3-month period at the beginning of 2012. Participants were recruited using both online and offline strategies and were required to complete surveys, both pre- and post-intervention, in a repeated measures design. RESULTS: Matched data were collected from 51 participants; the results showed AsthmaWise to be a feasible and acceptable method of delivering asthma education to the target population. Self-reported measures showed an increase in participants' asthma knowledge, asthma control and quality of life. Results from the Perceived Health Web Site Usability Questionnaire (PHWSUQ) showed improvements between usability testing and implementation. CONCLUSION: The need for asthma self-management education will continue to increase as the population ages and a greater number of older adults are living with asthma. This small pilot study indicates that an online asthma self-management education program can result in improved outcome measures in a target group not normally considered technologically literate.

BACKGROUND: Asthma in older adults is underdiagnosed and poorly self-managed. This population has little knowledge about the key symptoms, the prevalence among older adults, and the serious consequences of untreated asthma. The purpose of this study was to undertake a multifaceted evaluation of a social marketing campaign to increase asthma awareness among older adults in a regional Australian community. METHODS: A cohort of older adults in an intervention region (n = 316) and a control region (n = 394) were surveyed immediately prior to and following the social marketing campaign. Campaign awareness, message recall, materials recognition, and actions taken as a result of the campaign were assessed in both regions. Asthma knowledge and perceptions, experience of asthma symptoms, and general health were also assessed in both regions at baseline and follow-up. Analyses were conducted to explore the effects of the campaign in the intervention region, and to examine outcomes among different audience segments. RESULTS: The survey data showed that those in the target segments (Wheezers and Strugglers) had better message recall, and were more likely to report having taken action to control their respiratory symptoms. The campaign significantly increased the number of calls to an asthma information line from the target audience in the intervention community. CONCLUSIONS: A theory-based social marketing campaign conducted over 3-months increased the asthma information seeking behaviours of older adults in the intervention community compared to the control community. Recommendations are outlined for future community health promotion campaigns targeting older adults.

AIMS: The study aims to examine whether patterns of health behaviours (based on sleep duration, physical activity, screen time and diet) were associated with obesity in Australian children. METHODS: This paper included 1833 children aged 6-7 years (51.6% male) recruited in 2006 as part of the Longitudinal Study of Australian Children. Latent class analysis was performed to identify the presence of distinct behavioural profiles on the basis of sleep duration, physical activity, screen time and eating habits. Logistic regression was performed to examine the association between the behavioural profiles and obesity assessed at baseline and 2-year follow-up. RESULTS: Three behavioural profiles, healthy (27.7%), sedentary (24.8%) and short sleepers/unhealthy eaters (47.5%), were identified. Compared with the healthy profile, the sedentary profile (odds ratio = 1.59, 95% confidence interval (1.06-2.38)) and short sleepers/unhealthy eaters (odds ratio = 1.47 (1.03-2.13)) had elevated odds of obesity at 2-year follow-up. CONCLUSIONS: The present study identified distinct profiles of health behaviours in this sample of Australian children. These findings add to existing findings that many health behaviours co-occur and that obesity interventions should target patterns of behaviours in children.

BACKGROUND: Training for Australian general practice, or family medicine, can be isolating, with registrars (residents or trainees) moving between rural and urban environments, and between hospital and community clinic posts. Virtual communities of practice (VCoPs), groups of people sharing knowledge about their domain of practice online and face-to-face, may have a role in overcoming the isolation associated with general practice training. OBJECTIVE: This study explored whether Australian general practice registrars and their supervisors (trainers) would be able to use, and would be interested in using, a VCoP in the form of a private online network for work and training purposes. It also sought to understand the facilitators and barriers to intention to use such a community, and considers whether any of these factors may be modifiable. METHODS: A survey was developed assessing computer, Internet, and social media access and usage, confidence, perceived usefulness, and barriers, facilitators, and intentions to use a private online network for training purposes. The survey was sent by email link to all 139 registrars and 224 supervisors in one of Australia's 17 general practice training regions. Complete and usable responses were received from 131 participants (response rate=0.4). RESULTS: Most respondents had access to broadband at home (125/131, 95.4%) and at work (130/131, 99.2%). Registrars were more likely to spend more than 2 hours on the Internet (P=.03), and to use social media sites for nonwork purposes (P=.01). On a 5-point Likert scale, confidence was high (mean 3.93, SD 0.63) and was negatively associated with higher age (P=.04), but not associated with training stage. Social media confidence was lower, with registrars more confident than supervisors for almost all social media activities. On a 5-point Likert scale, overall usefulness was scored positively (n=123, mean 3.63, SD 0.74), and was not significantly associated with age or training level. The main concerns of respondents were worries about privacy (registrar: 61/81, 75.3%; supervisor: 30/50, 60.0%) and insufficient time (registrar: 41/81, 50.6%; supervisor: 36/50, 72.0%). Using a multivariate generalized linear regression model, training stage and perceived usefulness were positively predictive, and concerns about privacy and time were negatively predictive of intention to use a private online network. CONCLUSIONS: General practice registrars and supervisors are interested in using a private online network, or VCoP, for work and training purposes. Important considerations are the extent to which concerns such as privacy and usefulness may be overcome by training and support to offset some other concerns, such as time barriers. Participants at an early stage in their training are more receptive to using an online network. More senior registrars and supervisors may benefit from more training and promotion of the online network to improve their receptiveness.

There are many reasons why online self-management education is attractive to both patients and providers. AsthmaWise, an online self-management program, was developed using a Moodle platform, to enable older adults to learn asthma self-management skills. This study aimed to improve AsthmaWise through conducting: usability testing with a sample of end users; a cognitive walk-through undertaken by an independent health researcher; and assessment of content readability. A Perceived Health Web Site Usability Questionnaire score of 67% was achieved, indicating that there were usability issues that needed to be addressed. The cognitive walk-through and readability assessment identified unique issues that were not identified through usability testing with end users. The testing process allowed issues to be identified and rectified before piloting AsthmaWise, creating a more accessible and refined end product. The involvement of the site designer in the testing process was valuable and is highly recommended. This study shows that usability testing involving both end users and experts is an essential part of the design process that is relatively easy and inexpensive to undertake and can be effectively conducted by a nonexpert.

A review of the literature was conducted to identify the "active ingredients" needed to produce successful Internet interventions that support older adults in self-management of chronic disease. The term "Internet intervention" was used as an umbrella term to include all online self-management programs. Thirteen articles were found to meet the inclusion criteria from the initial 204 articles identified. Ritterband's Model of Internet Interventions was used as a framework to classify the intervention components reported. It was found that online self-management interventions can improve outcomes for some older adults. However, the wide diversity of interventions and the measures reported, coupled with the complex nature of the studies, made it difficult to identify the "active ingredients." To overcome this problem, the authors propose a minimum reporting set, the Internet Self-Management Uniform Reporting Framework, which can be used in the reporting of all interventions. Internet Self-Management Uniform Reporting Framework proposes the collection of specific data from six domains: Web site design, support, study design, Web site use, user characteristics and reporting outcomes. The adoption of Internet Self-Management Uniform Reporting Framework would enable easy comparison of online interventions targeting chronic diseases.

General practice training is a community of practice in which novices and experts share knowledge. However, there are barriers to knowledge sharing for general practioner (GP) registrars, including geographic and workplace isolation. Virtual communities of practice (VCoP) can be effective in overcoming these barriers using social media tools. The present study examined the perceived usefulness, features and barriers to implementing a VCoP for GP training. Following a survey study of GP registrars and supervisors on VCoP feasibility, a qualitative telephone interview study was undertaken within a regional training provider. Participants with the highest Internet usage in the survey study were selected. Two researchers worked independently conducting thematic analysis using manual coding of transcriptions, later discussing themes until agreement was reached. Seven GP registrars and three GP supervisors participated in the study (average age 38.2 years). Themes emerged regarding professional isolation, potential of social media tools to provide peer support and improve knowledge sharing, and barriers to usage, including time, access and skills. Frequent Internet-using GP registrars and supervisors perceive a VCoP for GP training as a useful tool to overcome professional isolation through improved knowledge sharing. Given that professional isolation can lead to decreased rural work and reduced hours, a successful VCoP may have a positive outcome on the rural medical workforce.

Obesity is associated with the increased incidence of colon cancer. Many cancer risk factors have been identified including increased blood levels of insulin, leptin, interleukin-6, interleukin-17, tumor necrosis factor-alpha, and decreased blood levels of adiponectin. However, the role of blood levels of estrogen in obesity-associated colon cancer is controversial. Evidence showed that obesity affected men more strongly than women in the carcinogenesis of colon cancer, indicating protective effect of estrogen which is increased in obesity. However, an epidemiological study has also shown that endogenous estradiol level is an independent risk factor for colon cancer, positively associated with colon cancer after normalizing insulin, IGF-1. The controversial opinions may be caused by different effects of ER-alpha and ER-beta. ER-alpha can increase colon cancer cell proliferation and increase cancer incidence. ER-beta has the opposite effect to ER-alpha, and it causes apoptosis of colon cancer cells. The normal colonocytes mainly express ER-beta. Therefore, increased estrogen in obesity may have protective effect via ER-beta in obesity-associated colon cancer. However, with the development of colon cancer, ER-alpha is increased and ER-beta is decreased. In the late stage of colon cancer, estrogen may promote cancer development via ER-alpha. The different effects and expression of ER-alpha and ER-beta may explain the different results observed in several epidemiological studies as well as several animal experiments. Therefore, manipulation of estrogen-caused signal pathways to inhibit ER-alpha and stimulate ER-beta may have preventive and therapeutic effect for obesity-associated colon cancer.

School break times provide a daily opportunity for children to be active; however, research indicates this time is underutilized. Reasons for low children's playground activity levels have primarily focused on physical barriers. This research aimed to contribute to physical environmental findings affecting children's playground physical activity levels by identifying additional variables through the interview process. Thirteen public schools were included in the sample (total 2946 children). Physical activity and environmental data were collected over 3 days. Environmental variables were manually assessed at each of the 13 schools. Observational data were used to determine which three schools were the most and least active. The principal, three teachers and 20 students in Grades 4-6 from these six schools (four lower and two average socioeconomic status) were invited to participate in the interview process. Student interviews involved the paired interview technique. The main themes generated from the school interviews included the effect of non-fixed equipment (including balls), playground markings, playground aesthetics, activity preference, clothing, the amount of break time available for play, teacher playground involvement, gender, bullying, school policies, student confidence in break-time activity and fundamental movement skills. The effect of bullying on playground physical activity levels was concerning.
