The Scatter of Medical Research and What to do About it.

by Laika Spoetnik in Laika's Medliblog

Paul Glasziou, GP and professor in Evidence Based Medicine, co-authored a new article in the BMJ [1]. Similar to another paper [2] I discussed before [3] this paper deals with the difficulty for clinicians of staying up-to-date with the literature. But where the previous paper [2,3] highlighted the mere increase in number of research articles over time, the current paper looks at the scatter of randomized clinical trials (RCTs) and systematic reviews (SR’s) accross different journals cited in one year (2009) in PubMed....

Can Guidelines Harm Patients?

by Laika Spoetnik in Laika's Medliblog

Recently I saw an intriguing “personal view” in the BMJ written by Grant Hutchison entitled: “Can Guidelines Harm Patients Too?” Hutchison is a consultant anesthetist with -as he calls it- chronic guideline fatigue syndrome. Hutchison underwent an acute exacerbation of his “condition” with the arrival of another set of guidelines in his email inbox. Hutchison:

On reviewing the level of evidence provided for the various recommendations being offered, I was struck by the fact that no relevant clinical trials had been carried out in the population of interest. Eleven out of 25 of the recommendations made were supported only by the lowest levels of published evidence ... Read more »

What Did Deep DNA Sequencing of Traditional Chinese Medicines (TCMs) Really Reveal?

by Laika Spoetnik in Laika's Medliblog

A recent study published in PLOS genetics[1] on a genetic audit of Traditional Chinese Medicines (TCMs) was widely covered in the news. The headlines are a bit confusing as they said different things. Some headlines say “Dangers of Chinese Medicine Brought to Light by DNA Studies“, others that Bear and Antelope DNA are Found in Traditional Chinese Medicine, and still others more neutrally: Breaking down traditional Chinese medicine.

What have Bunce and his group really done and what is the newsworthiness of this article?... Read more »

Evidence Based Point of Care Summaries [2] More Uptodate with Dynamed.

by Laika in Laika's Medliblog

This post is part of a short series about Evidence Based Point of Care Summaries or POCs. In this series I will review 3 recent papers that objectively compare a selection of POCs. In the previous post I reviewed a paper from Rita Banzi and colleagues from the Italian Cochrane Centre [1]. They analyzed 18 POCs with respect to their [...]... Read more »

Evidence Based Point of Care Summaries [1] No “Best” Among the Bests?

by Laika in Laika's Medliblog

For many of today’s busy practicing clinicians, keeping up with the enormous and ever growing amount of medical information, poses substantial challenges [6]. Its impractical to do a PubMed search to answer each clinical question and then synthesize and appraise the evidence. Simply, because busy health care providers have limited time and many questions per day. As [...]... Read more »

FUTON Bias. Or Why Limiting to Free Full Text Might not Always be a Good Idea.

by Laika in Laika's Medliblog

A few weeks ago I was discussing possible relevant papers for the Twitter Journal Club  (Hashtag #TwitJC), a succesful initiative on Twitter, that I have discussed previously here and here [7,8]. I proposed an article, that appeared behind a paywall. Annemarie Cunningham (@amcunningham) immediately ran the idea down, stressing that open-access (OA) is a pre-requisite for the TwitJC [...]...

PubMed’s Higher Sensitivity than OVID MEDLINE… & other Published Clichés.

by Laika in Laika's Medliblog

Is it just me, or are biomedical papers about searching for a systematic review often of low quality or just too damn obvious? I’m seldom excited about papers dealing with optimal search strategies or peculiarities of PubMed, even though it is my specialty. It is my impression, that many of the lower quality and/or less relevant papers are [...]... Read more »

HOT TOPIC: Does Soy Relieve Hot Flashes?

by Laika in Laika's Medliblog

The theme of the Upcoming Grand Rounds held at June 21th (1st day of the Summer) at Shrink Rap is “hot”. A bit far-fetched, but aah you know….shrinks“. Of course they hope  assume  that we will express Weiner-like exhibitionism at our blogs. Or go into spicy details of hot sexpectations or other Penis Friday NCBI-ROFL posts. But no, not me, [...]...

A New Safe Blood Test to Diagnose Down Syndrome

by Laika in Laika's Medliblog

The established method to prenatally diagnose chromosomal gross abnormalities is to obtain fetal cells from the womb with a fine needle, either by Amniocentesis (a sample of the fluid surrounding the foetus in the womb)  or by Chorionic villus sampling (CVS, a sample of the placenta taken via the vaginal route). The procedures are not to be sneezed [...]... Read more »

Much Ado About ADHD-Research: Is there a Misrepresentation of ADHD in Scientific Journals?

by Laika in Laika's Medliblog

The reliability of science is increasingly under fire. We all know that media often gives a distorted picture of scientific findings (i.e. Hot news: Curry, Curcumin, Cancer & cure). But there is also an ever growing number of scientific misreports or even fraud (see bmj editorial announcing retraction of the Wakefield paper about causal relation beteen MMR vaccination [...]...

Implementing Twitter in a Health Sciences Library

by Laika in Laika's Medliblog

Twitter describes itself as “a service for friends, family, and co-workers to communicate and stay connected through the exchange of quick, frequent answers to one simple question: What are you doing?” [2]. The “answers” are equally simple, because the tweet (that what is being “said”) must fit in 140 characters. The tweet does not only [...]... Read more »

A Filter for Finding “All Studies on Animal Experimentation in PubMed”

by Laika in Laika's Medliblog

For  an introduction to search filters you can first read this post. Most people searching PubMed try to get rid of publications about animals. But basic scientists and lab animal technicians just want to find those animal studies. PubMed has built-in filters for that: the limits. There is a limit  for “humans” and a limit for “animals”.

Does the NHI/FDA Paper Confirm XMRV in CFS? Well, Ditch the MR and Scratch the X… and… you’ve got MLV.

by Laika in Laika's Medliblog

The long awaited paper that would ‘solve’ the controversies about the presence of Xenotropic Murine Leukemia Virus-related virus (XMRV) in patients with chronic fatigue syndrome (CFS) was finally published in PNAS last week [1]. The study, a joint effort of the NIH and the FDA, was withheld, on request of the authors [2], because it contradicted [...]... Read more »

Collaborating and Delivering Literature Search Results to Clinical Teams Using Web 2.0 Tools

by Laika in Laika's Medliblog

There seem to be two camps in the library, the medical and many other worlds: those who embrace Web 2.0, because they consider it useful for their practice and those who are unaware of Web 2.0 or think it is just a fad. There are only a few ways the Web 2.0-critical people can be convinced: by [...]...

PubMed versus Google Scholar for Retrieving Evidence

by Laika in Laika's Medliblog

A while ago a resident in dermatology told me she got many hits out of PubMed, but zero results out of TRIP. It appeared she had used the same search for both databases: alopecea areata and diphenciprone (a drug with a lot of synonyms). Searching TRIP for alopecea (in the title) only, we found a Cochrane [...]... Read more »

What One Short Night’s Sleep does to your Glucose Metabolism

As a blogger I regularly sleep 3-5 hours just to finish a post. I know that this has its effects on how I feel the next day.
