Quality and readability of online patient information for abdominal aortic aneurysms
ObjectiveWe assessed the quality and readability of patient information for abdominal aortic aneurysms (AAAs) on the World Wide Web, as accessed from the United Kingdom.MethodsWeb sites returned by a simple Web search using the three largest search engines by market share were objectively and subjectively assessed for quality and readability. The Internet search engines Google, Yahoo!, and Bing were interrogated for the term “abdominal aortic aneurysm” and the first 50 hits screened. Organization type and Health on the Net status were recorded. Each unique site containing AAA information was scored for quality using the University of Michigan Consumer Health Web site Evaluation Checklist by two authors, and readability was calculated using the Flesch Reading Ease (FRE) score. Subjective content assessment was also undertaken.ResultsOf 150 hits, 112 were relevant, with 55 unique sites for assessment. Overall, the FRE score was 39 (range, 29-47) and the Michigan score was 36 (range, 25-56), with good interobserver agreement (rs = 0.83; P = .01). Michigan and FRE scores were poorly correlated (rs = 0.064; P = .6). Sites containing discussion on the merits of endovascular/open repair and the concept of an intervention threshold had the highest Michigan scores (58.5 [50-59.75] vs 28 [13-36.5]; P < .001). Search engine ranking, Health on the Net status, country of origin, and organization type did not affect quality or readability.ConclusionsThe current quality and readability of online patient information for AAAs is poor and requires significant improvement. Clinicians treating patients with AAAs should be aware of the limitations of the online “lay literature.
Elevated circulating amyloid concentrations in obesity and diabetes promote vascular dysfunction
Diabetes, obesity and Alzheimer’s disease (AD) are associated with vascular complications and impaired nitric oxide (NO) production. Furthermore, increased β-site amyloid precursor protein (APP)-cleaving enzyme 1 (BACE1), APP and β-amyloid (Aβ) are linked with vascular disease development and raised BACE1 and Aβ accompany hyperglycemia and hyperlipidemia. However, the causal relationship between obesity and diabetes, raised Aβ and vascular dysfunction is unclear. We report that diet-induced obesity (DIO) in mice raised plasma and vascular Aβ42 that correlated with decreased NO bioavailability, endothelial dysfunction and raised blood pressure. Genetic or pharmacological reduction of BACE1 activity and Aβ42 prevented and reversed, respectively, these outcomes. In contrast, expression of human mutant APP in mice or Aβ42 infusion into control diet-fed mice to mimic obese levels impaired NO production, vascular relaxation and raised blood pressure. In humans, raised plasma Aβ42 correlated with diabetes and endothelial dysfunction. Mechanistically, higher Aβ42 reduced endothelial NO synthase (eNOS), cyclic GMP and protein kinase G (PKG) activity independently of diet whereas endothelin-1 was increased by diet and Aβ42. Lowering Aβ42 reversed the DIO deficit in the eNOS-cGMP-PKG pathway and decreased endothelin-1. Our findings suggest that BACE1 inhibitors may have therapeutic value in the treatment of vascular disease associated with diabetes
NHS Health Check Programme rapid evidence synthesis
Background:
The NHS Health Check programme is the largest current prevention initiative in England. Since its introduction in 2009 a growing literature has been published evaluating the first eight years of the programme. These have been summarised in reports published by Public Health England but, to date, no synthesis has been performed. There is, therefore, a need for an independent, comprehensive, rapid evidence synthesis to identify what has been learnt about the NHS Health Check programme so far.
Aims and Objectives:
To provide a rapid synthesis of the published research evidence on NHS Health Checks, specifically addressing the six research questions posed by Public Health England:
1. Who is and who is not having an NHS Health Check?
2. What are the factors that increase take-up among the population and sub-groups?
3. Why do people not take up an offer of an NHS Health Check?
4. How is primary care managing people identified as being at risk of cardiovascular disease or with abnormal risk factor results?
5. What are patients’ experiences of having an NHS Health Check?
6. What is the effect of the NHS Health Check on disease detection, changing behaviours, referrals to local risk management services, reductions in individual risk factor prevalence, reducing cardiovascular disease risk and on statin and antihypertensive prescribing?
Design:
A systematic review with descriptive synthesis of quantitative data and thematic synthesis of qualitative data.
Data sources:
Medline, PubMed, Embase, Health Management Information Consortium (HMIC), Cumulative Index of Nursing and Allied Health Literature (CINAHL), Global Health, PsycInfo, Web of Science, the Cochrane Library, NHS Evidence, Google Scholar, Google, OpenGrey, Clinical Trials.gov, the ISRCTN registry, and article reference lists.
Study selection:
Studies identified by the searches were selected for inclusion in the review by two reviewers in a two-step process. First, studies relevant to the NHS Health Check were identified. These were then screened against predefined inclusion and exclusion criteria for each of the six research questions.
Data extraction:
At least two researchers assessed eligibility, extracted data, and assessed the quality of the included studies.
Key findings:
Coverage varies substantially across regions and in different settings. Multiple definitions used interchangeably make comparisons difficult. It is consistently higher in older people, females and more deprived populations but this may reflect targeting. Outreach services in the community can reach particular socio-demographic groups but better descriptions and robust evaluations are needed.
There is a lack of national level studies reporting the characteristics of those who take-up the invitation to an NHS Health Check.
Regional studies report uptake between 27% and 53%, similar to national reported uptake (48.3%). Older people, women in younger age groups and men in older age groups, and those from least deprived areas are more likely to take up invitations. Promising methods to increase uptake are modifications to the invitation (3-4% increase), and text message invites or reminders (up to 9% increase). There is a lack of quantitative evidence for the effect of community settings on uptake but qualitative evidence highlights their convenience and the value of community ambassadors.
People do not take up the offer of an NHS Health Check due to lack of awareness or knowledge, competing priorities, misunderstanding the purpose, an aversion to preventive medicine, difficulty getting an appointment with a GP, and concerns about privacy and confidentiality of pharmacies. Amongst attendees there are high levels of satisfaction (over 80%). Some reported attendance had acted as a wake-up call and precipitant for lifestyle changes. Others were left with feelings of unmet expectations, were confused about or unable to remember their risk scores, and found lifestyle advice too simplistic and un-personalised.
There are wide variations in the process, delivery and content of NHS Health Checks across the country, in part due to different local implementation. Regardless of region or setting those delivering NHS Health Checks reported challenges with workload, IT, funding, and training. Amongst general practice professionals there were concerns about inequality of uptake and doubts about the evidence underpinning the programme and the cost-effectiveness.
NHS Health Checks are associated with small increases in disease detection. There is very little data on behaviour change or referrals to lifestyle services. NHS Health Checks are associated with a 3-4% increase in prescribing of statins
Forgiveness-Reconciliation and Communication-Conflict-Resolution Interventions Versus Retested Controls in Early Married Couples
The first 6 months of marriage are optimal for marriage enrichment interventions. The Hope-Focused Approach to couple enrichment was presented as two 9-hr interventions--(a) Handling Our Problems Effectively (HOPE), which emphasized communication and conflict resolution, and (b) Forgiveness and Reconciliation through Experiencing Empathy (FREE). HOPE and FREE were compared with repeated assessment controls. Couples were randomly assigned and were assessed at pretreatment (t1); 1 month posttreatment (t2) and at 3- (t3), 6- (t4), and 12-month (t5) follow-ups using self-reports. In addition to self-report measures, couples were assessed at t1, t2, and t5 using salivary cortisol, and behavioral coding of decision making. Of 179 couples who began the study, 145 cases were analyzed. Both FREE and HOPE produced lasting positive changes on self-reports. For cortisol reactivity, HOPE and FREE reduced reactivity at t2, but only HOPE at t5. For coded behaviors, control couples deteriorated; FREE and HOPE did not change. Enrichment training was effective regardless of the focus of the training
Information and Risk Modification Trial (INFORM): design of a randomised controlled trial of communicating different types of information about coronary heart disease risk, alongside lifestyle advice, to achieve change in health-related behaviour
Abstract
Background
Cardiovascular disease (CVD) remains the leading cause of death globally. Primary prevention of CVD requires cost-effective strategies to identify individuals at high risk in order to help target preventive interventions. An integral part of this approach is the use of CVD risk scores. Limitations in previous studies have prevented reliable inference about the potential advantages and the potential harms of using CVD risk scores as part of preventive strategies. We aim to evaluate short-term effects of providing different types of information about coronary heart disease (CHD) risk, alongside lifestyle advice, on health-related behaviours.
Methods/Design
In a parallel-group, open randomised trial, we are allocating 932 male and female blood donors with no previous history of CVD aged 40–84 years in England to either no intervention (control group) or to one of three active intervention groups: i) lifestyle advice only; ii) lifestyle advice plus information on estimated 10-year CHD risk based on phenotypic characteristics; and iii) lifestyle advice plus information on estimated 10-year CHD risk based on phenotypic and genetic characteristics. The primary outcome is change in objectively measured physical activity. Secondary outcomes include: objectively measured dietary behaviours; cardiovascular risk factors; current medication and healthcare usage; perceived risk; cognitive evaluation of provision of CHD risk scores; and psychological outcomes. The follow-up assessment takes place 12 weeks after randomisation. The experiences, attitudes and concerns of a subset of participants will be also studied using individual interviews and focus groups.
Discussion
The INFORM study has been designed to provide robust findings about the short-term effects of providing different types of information on estimated 10-year CHD risk and lifestyle advice on health-related behaviours.

Comment Re: Non-Compete Clause Rulemaking, Matter No. P201200
Within signed law professors and law students submitted this letter to the Federal Trade Commission, writing in their individual capacities, not as agents of their affiliated institutions, in support of the Federal Trade Commission’s proposed rule to ban most non-compete clauses (the “Proposal”) as an unfair method of competition.
This letter offers comments in response to areas where the FTC has requested public comment. To make our views clear, this letter contains the following sections:
I. Summary of the Proposal;
II. The Commission Should Consider Expanding Its Definition of Non-Compete Clauses to Prevent Employers from Requiring Workers to Quit Before Seeking Alternative Employment;
III. Non-Compete Clauses Are Unfair Methods of Competition;
IV. Non-Compete Clauses Negatively Impact Workers and Their Families;
V. The Proposed Rule Protects Small Businesses and Entrepreneurs; and
VI. The Commission Should Consider a Factor Test for Its Unfairness Analysis for Senior Executive
Proactive role-orientation toward workplace safety: Psychological dimensions, nomological network and external validity
In the light of the relevance of workers’ participation and initiative in improving safety in the workplace, a new measurement tool is presented to assess multiple psychological drivers (proactive motivations; future orientations) which support a proactive orientation by individuals toward safety management and accident prevention in the workplace. This validation study was developed with a survey methodology in two industrial samples (N = 327; 196) from the chemical and manufacturing sectors. The factor structure of the tool was tested with CFA’s. The analyses evidenced the goodness of a multidimensional structure, with a general superordinate dimension indicator of the overall construct of individuals’ proactive safety-role orientation. Moreover, the analysis of the nomological network of the new model showed positive correlations with both behavioral criteria (safety voice; safety initiative) and supervision antecedents (safety-specific transformational leadership) which were measured at the individual level. Finally, the external validity was positively verified by significant correlations with organizational outcomes assessed at the team level through external measures (supervisor evaluations; data archives) which were collected at team level (N = 32) in the following six months from the main survey. Theoretical and practical implications with indications for future research conclude the article
Effect of communicating phenotypic and genetic risk of coronary heart disease alongside web-based lifestyle advice:the INFORM Randomised Controlled Trial
Objective To determine whether provision of web-based lifestyle advice and coronary heart disease risk information either based on phenotypic characteristics or phenotypic plus genetic characteristics affects changes in objectively measured health behaviours. Methods A parallel-group, open randomised trial including 956 male and female blood donors with no history of cardiovascular disease (mean SD age=56.7 8.8 years) randomised to four study groups: control group (no information provided); web-based lifestyle advice only (lifestyle group); lifestyle advice plus information on estimated 10-year coronary heart disease risk based on phenotypic characteristics (phenotypic risk estimate) (phenotypic group) and lifestyle advice plus information on estimated 10-year coronary heart disease risk based on phenotypic (phenotypic risk estimate) and genetic characteristics (genetic risk estimate) (genetic group). The primary outcome was change in physical activity from baseline to 12 weeks assessed by wrist-worn accelerometer. Results 928 (97.1%) participants completed the trial. There was no evidence of intervention effects on physical activity (difference in adjusted mean change from baseline): lifestyle group vs control group 0.09 milligravity (mg) (95% CI-1.15 to 1.33); genetic group vs phenotypic group-0.33 mg (95% CI-1.55 to 0.90); phenotypic group and genetic group vs control group-0.52 mg (95% CI-1.59 to 0.55) and vs lifestyle group-0.61 mg (95% CI-1.67 to 0.46). There was no evidence of intervention effects on secondary biological, emotional and health-related behavioural outcomes except self-reported fruit and vegetable intake. Conclusions Provision of risk information, whether based on phenotypic or genotypic characteristics, alongside web-based lifestyle advice did not importantly affect objectively measured levels of physical activity, other health-related behaviours, biological risk factors or emotional well-being.

Airborne Bacteria in Earth's Lower Stratosphere Resemble Taxa Detected in the Troposphere: Results From a New NASA Aircraft Bioaerosol Collector (ABC)
Airborne microorganisms in the upper troposphere and lower stratosphere remain elusive due to a lack of reliable sample collection systems. To address this problem, we designed, installed, and flight-validated a novel Aircraft Bioaerosol Collector (ABC) for NASA's C-20A that can make collections for microbiological research investigations up to altitudes of 13.7 km. Herein we report results from the first set of science flights—four consecutive missions flown over the United States (US) from 30 October to 2 November, 2017. To ascertain how the concentration of airborne bacteria changed across the tropopause, we collected air during aircraft Ascent/Descent (0.3 to 11 km), as well as sustained Cruise altitudes in the lower stratosphere (~12 km). Bioaerosols were captured on DNA-treated gelatinous filters inside a cascade air sampler, then analyzed with molecular and culture-based characterization. Several viable bacterial isolates were recovered from flight altitudes, including Bacillus sp., Micrococcus sp., Arthrobacter sp., and Staphylococcus sp. from Cruise samples and Brachybacterium sp. from Ascent/Descent samples. Using 16S V4 sequencing methods for a culture-independent analysis of bacteria, the average number of total OTUs was 305 for Cruise samples and 276 for Ascent/Descent samples. Some taxa were more abundant in the flight samples than the ground samples, including OTUs from families Lachnospiraceae, Ruminococcaceae and Erysipelotrichaceae as well as the following genera: Clostridium, Mogibacterium, Corynebacterium, Bacteroides, Prevotella, Pseudomonas, and Parabacteroides. Surprisingly, our results revealed a homogeneous distribution of bacteria in the atmosphere up to 12 km. The observation could be due to atmospheric conditions producing similar background aerosols across the western US, as suggested by modeled back trajectories and satellite measurements. However, the influence of aircraft-associated bacterial contaminants could not be fully eliminated and that background signal was reported throughout our dataset. Considering the tremendous engineering challenge of collecting biomass at extreme altitudes where contamination from flight hardware remains an ever-present issue, we note the utility of using the stratosphere as a proving ground for planned life detection missions across the solar system
