Hide Abstract
Civilian literature has reported excellent outcomes after elective fasciotomy for chronic exertional compartment syndrome (CECS). Our study's purpose was to objectively investigate the functional outcome of fasciotomies performed for CECS in a high demand military population.

Review of the current literature as a preparatory tool for the trauma content of the Orthopaedic in-Training Examination.

Hide Abstract
Currently, the only standardized evaluation of trauma knowledge throughout orthopedic training is found in the Orthopaedic In-Training Examination, which is administered annually to all residents by the American Academy of Orthopaedic Surgeons. Our goals were to assess the Orthopaedic In-Training Examination to (1) determine the content of the trauma questions, (2) identify the content of the 3 most frequently referenced journals on the answer keys, and (3) evaluate the correlation between those contents.We reviewed the trauma-related Orthopaedic In-Training Examination questions and answer keys for 2002 through 2007. Content for test questions and cited literature was assessed with the same criteria: (1) category type, (2) anatomic location, (3) orthopedic focus, and (4) treatment type. For each of the 3 most frequently referenced journals, we weighted content by dividing the number of times it was referenced by the number of its trauma-related articles. We then compared the journal data individually and collectively to the data from the Orthopaedic In-Training Examination trauma questions. A chi-square analysis with Yates correction was used to determine differences. Questions and literature were similar in the most frequently addressed items in each of the 4 areas: category type (taxonomy 3, treatment), 52.4% and 60.7%, respectively; anatomic location (femur), 23.3% and 27.7%, respectively; orthopedic focus (fracture), 51.0% and 56.5%, respectively; and treatment type (multiple/nonspecific), 39.0% and 35.4%, respectively.The content correlation found between the questions and literature supports the idea that reviewing current literature may help prepare for the trauma content on the Orthopaedic In-Training Examination.

Relationships between physiological characteristics and trace metal body burdens of banded garden spiders Argiope trifasciata (Araneae, Araneidae).

Hide Abstract
Banded garden spiders (Argiope trifasciata) were collected at the Ballona Wetlands, a metal contaminated salt marsh. The relationship between spider body size and individual metal loads was investigated. Biochemical markers were identified in spider fecal material and found to correlate to body metal levels. Body metal dry weight concentrations of Cd, Cr, Cu, Zn and total metals in female A. trifasciata exhibited distinct patterns of spatial and annual variation during 2006 and 2007. Spider body size was homogeneous across sites in both years, while increased Cd and Cr concentrations were sometimes associated with a reduction in spider size, though the influence of Cr was quite minor. Spiders with higher body Cu levels showed a reduction in peak area for hypoxanthine and an un-identified component in fecal material chromatograms. Spatial and annual differences in metal bioaccumulation are likely mediated by variation in site-specific environmental parameters and rainfall, while the negative relationships between body size and metal levels are presumably a consequence of a spiders expenditure of energy for metal tolerance mechanisms vs. foraging and growth. Finally, correlating body metal levels with excreta products constitutes a novel method to non-invasively predict metal levels in spiders.

G-octamer formation from N? modified guanine derivatives.
Nucleosides Nucleotides Nucleic Acids

Show Abstract
Hide Abstract
The properties of the self-assembly of two lipophilic guanine derivatives, 2,3,5-O-tris(tert-butyldimethylsilyl)-guanosine and N?-(3,5-bis(tert-butyldimethylsilyloxy)-benzyl)-guanine, are described. In the presence of K+, both guanine derivatives self-associate into D?-symmetric octamers consisting of two G-quartets stacked around a central ion.

Studies during early development have shown that the precursor availability of amino acids directly affects protein synthesis both at the whole-body level and for select organ tissues, although this has not been studied for the brain.

Effective tuberculosis (TB) control in HIV-prevalent settings is hindered by absence of accurate, rapid TB diagnostic tests. We evaluated the accuracy of a urine lipoarabinomannan (LAM) test for TB diagnosis in South Africa.

Pain reporting, opiate dosing, and the adverse effects of opiates after hip or knee replacement in patients 60 years old or older.

Show Abstract
Hide Abstract
Our goal was to determine whether there were age-related differences in pain, opiate use, and opiate side effects after total hip or knee arthroplasty in patients 60 years old or older. We hypothesized that there would be no significant differences between age groups in (1) mean pain score, (2) opiate use after adjusting for pain, or (3) opiate side effects after adjusting for opiate use and pain score. We retrospectively reviewed the electronic and paper charts of all patients undergoing total joint replacements at our institution over 3 years who met the following criteria: (1) 60 years old or older, (2) primary single total knee or total hip replacement, and (3) no preoperative dementia. Preoperative, intraoperative, and postoperative course data were collected using a customized data entry process and database. We divided the patients into 2 age groups, those 60 to 79 years old and those 80 years old or older. Using a marginal model with the panel variable of postoperative day, we investigated the associations between age group and pain, age group and pain adjusting for opiate use, and age group and complications (respiratory depression, naloxone usage as a measure of respiratory arrest, delirium, constipation, and urinary retention) adjusting for opiate use (Xtgee, Stata10, Stata Corp. LP, College Station, Texas). Significance was set at P < .05. We found no significant difference in pain scores between groups, but the older group had significantly fewer opiates prescribed yet significantly more side effects, including delirium (odds ratio 4.2), than did the younger group, even after adjusting for opiate dose and pain score.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
