The Dangers Of Snow Shoveling
From the 28 November 2011 Medical News Today article
Urban legend warns shoveling snow causesheart attacks, and the legend seems all too accurate, especially for male wintery excavators with a family history of premature cardiovascular disease. However, until recently this warning was based on anecdotal reports. …
…
Dr. Baranchuk and his team retrospectively reviewed KGH patient records from the two previous winter seasons and discovered that of the 500 patients who came to the hospital with heart problems during this period, 7 per cent (35 patients) had started experiencing symptoms while shoveling snow.
“That is a huge number,” says Dr. Baranchuk. “7 per cent of anything in medicine is a significant proportion. Also, if we take into account that we may have missed some patients who did not mention that they were shoveling snow around the time that the episode occurred, that number could easily double.”
The team also identified three main factors that put individuals at a high risk when shoveling snow. The number one factor was gender (31 of the 35 patients were male), the second was a family history of premature coronary artery disease (20 of the 35 patients), and the third was smoking (16 out of 35 patients). The second two factors may carry much more weight than the first, however, since the team could not correct for high rate of snow shoveling among men in their sample.
A history of regularly taking four or more cardiac medications was found to be preventative.

Using Social Media to Enhance Your Research
Excerpts from Using Social Media to Enhance Your Research, at the Krafty Librarian blog
Daniel Hooker posted some nice slides on Using Social Media to Advance Your Research that he presented to a group of PhDs and post-docs at the UBC Faculty of Medicine. I gave a similar presentation to World Health Interest Group at Case Western Reserve University. I spoke about using blogs, Twitter, wikis, etc. in scientific research.
During my presentation some of the attendees got hung up on the tools and technologies as toys and the idea of communicating was lost. Social media is just one method people can use to communicate, share ideas, protocols, methods, lab notes, etc. In the very broadest of terms, email is sort of social media. You can email many people who can then pass that discussion along to others. Listservs are a perfect example of this. But email has been around with us for such a long time that there is no real discussion about its communication potential. Yet, email was once a new fangled communication toy.
Read this abstract from Science 1982. 12;215(4534):843-52.
Computer networks are an integral part of the rapid expansion of computing. Their emergence depends both on evolving communication technologies, such as packet-switching and satellites, and on diverse experiments and innovations in the software tools that exploit communications. The tools provide computer users with facilities such as electronic mail, access to remote computers, and electronic bulletin boards. Scientists can both adapt and extend tools to meet the communication needs of their work, and several networks are developing to serve particular scientific communities.

The easiest way to have a rich and informative Twitter feed is to follow the people the leaders in your field are following and branch off from there. By the way, Twitter’s site is ok for learning, but it really stinks for following any sort of conversation AND you always have to refresh the page (annoying). I highly recommend using Hootsuite or TweetDeck to monitor your Twitter feeds. The thing I like about TweetDeck is that a little message pops up in the corner of my computer screen with the tweet. I can read it quickly and decide whether I want to ignore it, comment, or click on their link. Using Twitter on TweetDeck this way is very similar to how I use email because my email pops messages to my main screen too.
Really you need to sit down and figure out what your information needs are and the leaders in your field to follow. This might be hard, but I bet there might be somebody in your field who is already doing it, so ask them, build off of what they are doing and tweek it to fit your needs.
PubMed Health – A Growing Resource for Clinical Effectiveness Information

From the November NLM Technical Bulletin article
PubMed Health — A Growing Resource for Clinical Effectiveness Information
PubMed® Health developed further as a resource for clinical effectiveness research with its August and September 2011 releases. Growing from around 200 items based on systematic reviews to over 5,000, PubMed Health has also begun a collection focused on helping people understand systematic reviews and their results. PubMed Health goals are: helping users find the evidence that could answer their questions about effects of health care and helping them understand what they find.
Making Systematic Reviews More Accessible
Systematic reviews that identify and interpret studies on the effects of health care form an essential research basis for informed decision-making. Systematic reviewing has been growing, especially with the advent of The Cochrane Collaboration and the increasing incorporation of this methodology in health technology assessment by public agencies and clinical practice guideline development.Systematic reviews (including health technology assessments) are often lengthy and highly technical. Their evolution has been accompanied by a growth in knowledge translation activity. Along with traditional abstracts, various forms have been developed to help people use systematic reviews: executive and policymaker summaries, summaries or other forms for patients/consumers and summaries for clinicians.
However, these materials have been scattered widely on content providers’ Web sites without being collected centrally. Many of the systematic reviews undertaken by public health technology assessment agencies have also remained outside the National Library of Medicine® (NLM®) system. The PubMed Health initiative is gathering them together within a single searchable resource.
PubMed Health Content
PubMed Health contains systematic reviews and summaries of systematic reviews undertaken or updated in roughly the last ten years. The time limit is applied to publication date of around eight years, to allow for the time lag from the date of the evidence search. The cut-off currently is 2003.New content incorporated in these releases include summaries from The Cochrane Collaboration and the National Health Service (NHS) National Institute for Health Research (NIHR) Health Technology Assessment Programme. There are also full text reviews from the U.S. Agency for Healthcare Research and Quality (AHRQ), the Drug Effectiveness Review Project (DERP) at Oregon Health & Science University (OHSU), England’s National Institute for Health and Clinical Excellence (NICE) guidelines program, and the Department of Veterans Affairs’ Evidence-based Synthesis Program. From NHS Choices comes “Behind the Headlines”, its educational service on the science behind the news. These new content providers join PubMed Health original consumer clinical effectiveness content for consumers content provided by AHRQ and the German Institute for Quality and Efficiency in Health Care (IQWiG).
The reviews and review summaries now in PubMed Health account for perhaps one-third of the good quality systematic reviews published by public agencies and journals worldwide. Most of the remainder can be found in PubMed “Clinical Queries” Systematic Reviews search which runs simultaneously with a PubMed Health search; those PubMed results are presented as links on the right-hand portion of the results page (see #3 in Figure 4).
Organization
The re-designed homepage (see Figure 1) includes four key sections:
- Contents: a complete alphabetical listing of all titles, sorted by type of content.
- Behind Headlines: the NHS guide to the science behind health stories in the news.
- New & updated: content added in the last 60 days.
- Featured reviews: high quality reviews on interesting topics are selected and featured here. “Previously featured reviews” are provided in an RSS feed to which people can subscribe.
- Understanding clinical effectiveness: an explanation of clinical effectiveness research along with a section focusing on resources to help people understand systematic reviews and interpret the results.
Figure 1: PubMed Health homepage.A drop-down box under “Contents” (see Figure 2) shows the categories of information currently included in PubMed Health where these are available:
- For consumers: includes consumer summaries of systematic reviews as well as consumer information based on systematic reviews.
- Executive summaries: executive or policymaker summaries of systematic reviews.
- Clinical guides: clinician summaries of systematic reviews as well as clinical practice guidelines that are based on a fully reported systematic review.
- Full text reviews: systematic reviews with full texts, including PDF versions.
- Medical encyclopedia: medical and drug information for consumers for supplementary background information.
PubMed Health includes content that is currently also cited in PubMed, and PubMed Health will systematically be building in links to these citations. However, there will be some time lag for many items between inclusion in PubMed Health and citation in PubMed. Consumer content from PubMed Health is currently not included in PubMed.
Figure 2: Contents drop-down box.At the top right-hand corner (see Figure 3), “About PubMed Health” explains the Web site and the National Center Biotechnology Information, NLM, with a full listing of content providers. “Help” includes explanation of basic functions, along with suggested citations for PubMed Health content.
Figure 3: About PubMed Health and Help features.Searching
The primary search (see #1 in Figure 4) returns clinical effectiveness content by relevance, with the option of viewing all (default) or only specified content types. Relevant medical encyclopedia results are shown at the right (see #2 inFigure 4), with the results of the “Clinical Queries” filter search for systematic reviews in PubMed showing below those (see #3 in Figure 4). “Clinical Queries” returns results chronologically.
Figure 4: Search results.Additional Features
With medical encyclopedia content, PubMed Health has enhanced the display of anatomical images and given this popular feature a more prominent position. There are links from the medical encyclopedia diseases and conditions pages to MedlinePlus® content.PubMed Health now features “Add this” sharing for e-mail and social media. Coming in the fall, PubMed Health will begin a Twitter feed, announcing new content providers and features, as well as featured content.

Biomedical research gets its head into cloud computing
Translational research tool could mean creation of new Ohio-based tech support center
(Ohio State University Medical Center) Cloud computing is a term used to describe a system that allows easy access to a shared pool of resources. The “cloud” acts like a virtual supercomputer that can pull together a cluster of other computers to work together to perform certain tasks. The system works well when the data that are being stored, accessed and shared are in common formats that are universally “recognized” by end user tools. But research data are often not captured or stored in formats that are compatible.“With the current technology, a researcher might dedicate more than 100 hours to connect the dots between a set of tissue samples, the individual medical histories for the patients who provided those tissues, and then analyzing the group as a whole. With the TRIAD platform, researchers can now execute this type of search and analysis in minutes,” says Philip R. O. Payne, chair of the department of biomedical informatics at The Ohio State University Medical Center….

How it Works
Cloud computing is a term used to describe a system that allows easy access to a shared pool of resources (e.g., applications, servers, storage, networks) that can be quickly allocated and released with minimal effort by an administrator. The “cloud” acts like a virtual supercomputer that can pull together a cluster of other computers to work together to perform certain tasks. The system works well when the data that are being stored, accessed and shared are in common formats that are universally “recognized” by end user tools.

Elsevier wants to create an incubation environment
From the 8 August 2011 Science Intelligence and InfoPros blog posting
In this podcast from Copyright Clearance Center, Rafael Sidi, Elsevier talks about a new app ecosystem.
Sidi explains that “as a scientific publishing company, we are moving to a solution space and we don’t want to be just an information provider, but we want to also provide solutions to our customers, to our market… We want to go to the community, collaborate with the community and build the solutions together with the community.”
In order to have their “data easily remixable, reusable,” they are “going to the crowd. We are letting them play with our data and build on top of our data stuff that they need to build, because at the end, scientists and researchers, they know their problem better than us.”
With the main goal to accelerate science, Elsevier reaches out to the community in hopes to collaborate to find new solutions. “We want to create an incubation environment for the scientific and research community. [In some case], we providing some seed funding to startup companies… Our goal for the future, definitely, we want to create an Elsevier incubation environment.”

Journal of Visualized Experiments

The Journal of Visualized Experiments is a peer reviewed, PubMed indexed journal devoted to the publication of biological, medical, chemical and physical research in a video format.
The editors believe that videos of techniques and procedures will greatly aid scientists in learning and keeping abreast of new advancements in scientific methods. They will be able to focus their time and thought more on other experimental aspects and thus speed up the process from hypothesis generating to publication.
