The effect of an 8-week treatment program using a novel foot neuromuscular electrical stimulator on physical function, leg pain, leg symptoms, and leg blood flow in community-dwelling older adults: a randomized sham-controlled trial

However, studies using NMES devices in an elderly, ambulant, and otherwise apparently healthy population are lacking; this is despite the use of such devices being indicated for lower leg symptoms (such as aches, pain, and cramps) that are frequently seen in older individuals. The main purpose of this study is to evaluate the effect of non-invasive foot NMES (administered using Revitive Medic©) on such symptoms compared to a sham in a 12-week period. Methods: This is a single-center, single (participant)-blind, parallel-group, randomized, placebo-controlled (sham group), interventional study. Participants will be randomized to 1 of 3 groups (1:1:1) with each study group receiving a different type of foot NMES: Revitive sham; Revitive Medic© Program 1; or Revitive® Program 2. Each participant will be instructed to self-administer the foot NMES device for 30 min twice daily for 8 weeks. During the study, all participants will continue with their normal life, activities, medications, and diet with no restrictions. Following the 8-week NMES treatment program participants will be assessed for Canadian Occupational Performance Measure performance (COPM-P) and satisfaction (COPM-S) scores, lower leg pain, lower leg symptoms (heaviness, tiredness, aching and cramps), and blood flow volume and intensity. Discussion: Revitive® foot NMES has been proven to increase blood circulation in the legs during use, which may help to relieve symptoms such as pain, heaviness, cramps, and tiredness. When NMES is applied to the plantar surface of the feet it indirectly induces contraction of the calf muscle, activating the musculo-venous pump and thus improving circulation. This study aims to provide data informing on the applicability of foot NMES for the management of leg symptoms that are likely to be indicative of poor circulation in an elderly (> 65 years) community population.

Acetabular fractures following rugby tackles: a case series

<p>Abstract</p> <p>Introduction</p> <p>Rugby is the third most popular team contact sport in the world and is increasing in popularity. In 1995, rugby in Europe turned professional, and with this has come an increased rate of injury.</p> <p>Case presentation</p> <p>In a six-month period from July to December, two open reduction and internal fixations of acetabular fractures were performed in young Caucasian men (16 and 24 years old) who sustained their injuries after rugby tackles. Both of these cases are described as well as the biomechanical factors contributing to the fracture and the recovery. Acetabular fractures of the hip during sport are rare occurrences.</p> <p>Conclusion</p> <p>Our recent experience of two cases over a six-month period creates concern that these high-energy injuries may become more frequent as rugby continues to adopt advanced training regimens. Protective equipment is unlikely to reduce the forces imparted across the hip joint; however, limiting 'the tackle' to only two players may well reduce the likelihood of this life-altering injury.</p

Large expert-curated database for benchmarking document similarity detection in biomedical literature search

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe
