US Medical Specialty Global Health Training and the Global Burden of Disease
Background: Rapid growth in global health activity among US medical specialty education programs has lead to heterogeneity in types of activities and global health training models. The breadth and scope of this activity is not well chronicled.
Methods: Using a standardized search protocol, we examined the characteristics of US medical residency global health programs by number of programs, clinical specialty, nature of activity (elective, research, extended curriculum based field training), and geographic location across seven different clinical medical residency education specialties. We tabulated programmatic activity by clinical discipline, region and country. We calculated the Spearman\u27s rank correlation coefficient to estimate the association between programmatic activity and countryâlevel disease burden.
Results: Of the 1856 programs assessed between January and June 2011, there were 380 global health residency training programs (20%) working in 141 countries. 529 individual programmatic activities (electiveâbased rotations, research programs, extended curriculumâ based field training, or other) occurred at 1337 specific sites. The majority of the activities consisted of electiveâbased rotations. At the country level, disease burden had a statistically significant association with programmatic activity (Spearman\u27s Ï = 0.17) but only explained 3% of the total variation between countries.
Conclusions: There were a substantial number of US medical specialty global health programs, but a relative paucity of surgical and mental health programs. Electiveâbased programs were more common than programs that offer longitudinal experiences. Despite heterogeneity, there was a small but statistically significant association between program location and the global burden of disease. Areas for further study include the degree to which USâbased programs develop partnerships with their program sites, the significance of this activity for training, and number and breadth of programs in medical specialty global health education in other countries around the world

Disparities in health in the United States: An overview of the social determinants of health for otolaryngologists
Objectives: Social determinants of health include social and demographic factors such as poverty, education status, race and ethnicity, gender, insurance status, and other factors that influence (1) development of illness, (2) ability to obtain and utilize healthcare, and (3) health and healthcare outcomes. In otolaryngology, as in other subspecialty surgical fields, we are constantly confronted by patientsâ social and demographic circumstances including poverty, language barriers, and lack of health insurance and yet there is limited research on how these factors impact health equity in our field, or how attention to these patient characteristics may improve health equity. This review provides the reader with a framework to understand the social determinants of health including how socioeconomic status, insurance status, race, gender, and other factors impact health. Data Sources and Review Methods Foundational papers on the social determinants of health are reviewed, as well as otolaryngology publications focused on health and healthcare disparities. Results: The social determinants of health have a major impact on patient health as well as healthcare utilization, but there is a relative lack of data on these factors and how they can be addressed within otolaryngology. Incorporating tools to measure social and demographic characteristics and actually report on these measures is a first simple step to increase the data on the social determinants of health as they pertain to otolaryngology. Conclusion: More research is needed on the social determinants of health, and how they impact otolaryngic disease. Medicare's Accountable Care Organization models will increasingly change the way in which physicians are reimbursed, making the social determinants of health central not only to our moral conscience but also the bottom line.

Inter-rater reliability of three standardized functional tests in patients with low back pain
<p>Abstract</p> <p>Background</p> <p>Of all patients with low back pain, 85% are diagnosed as "non-specific lumbar pain". Lumbar instability has been described as one specific diagnosis which several authors have described as delayed muscular responses, impaired postural control as well as impaired muscular coordination among these patients. This has mostly been measured and evaluated in a laboratory setting. There are few standardized and evaluated functional tests, examining functional muscular coordination which are also applicable in the non-laboratory setting. In ordinary clinical work, tests of functional muscular coordination should be easy to apply. The aim of this present study was to therefore standardize and examine the inter-rater reliability of three functional tests of muscular functional coordination of the lumbar spine in patients with low back pain.</p> <p>Methods</p> <p>Nineteen consecutive individuals, ten men and nine women were included. (Mean age 42 years, SD ± 12 yrs). Two independent examiners assessed three tests: "single limb stance", "sitting on a Bobath ball with one leg lifted" and "unilateral pelvic lift" on the same occasion. The standardization procedure took altered positions of the spine or pelvis and compensatory movements of the free extremities into account. The inter-rater reliability was analyzed by Cohen's kappa coefficient (Îș) and by percentage agreement.</p> <p>Results</p> <p>The inter-rater reliability for the right and the left leg respectively was: for the single limb stance very good (Îș: 0.88â1.0), for sitting on a Bobath ball good (Îș: 0.79) and very good (Îș: 0.88) and for the unilateral pelvic lift: good (Îș: 0.61) and moderate (Îș: 0.47).</p> <p>Conclusion</p> <p>The present study showed good to very good inter-rater reliability for two standardized tests, that is, the single-limb stance and sitting on a Bobath-ball with one leg lifted. Inter-rater reliability for the unilateral pelvic lift test was moderate to good. Validation of the tests in their ability to evaluate lumbar stability is required.</p

O1s binding energy measured by X-ray photoelectron spectroscopy (XPS) is candidate as a new tool to determine a new scale of Lewis basicity of oxide ions in glass. Some mathematical expressions for the basicity or XPS chemical shift, such as charge parameter and optical basicity, were compared with the experimental O1s binding energy in binary alkali oxide glasses. The expressions so far in use needed some modification in parameters. A new empirical expression introduced in this paper gives a new concept and universal scale of basicity
The unrecognised cost of cancer patients' unrelieved symptoms:a nationwide follow-up of their surviving partners
We investigated if a cancer patient's unrelieved symptoms during the last 3 months of life increase the risk of long-term psychological morbidity of the surviving partner. All women (n=506) living in Sweden under 80 years of age, who lost their husband/partner owing to cancer of the prostate in 1996 or of the urinary bladder in 1995 or 1996 were asked to answer an anonymous postal questionnaire, 2â4 years after their loss. The widows' psychological morbidity was associated with the patient's unrelieved mental symptoms. When the patient was perceived to have been very anxious during last three months of life (compared to no observed symptoms) the relative risks for the widows' psychological morbidity were: 2.5 (1.4â4.3) for depression and 3.4 (1.4â8.2) for anxiety. When comparing reports of the patient's pain (much vs no), the relative risks were 0.8 (0.5â1.2) for widowhood depression, and 0.8 (0.4â1.7) for widowhood anxiety. The patients were found to have had adequate access to physical pain control but poor access to psychological symptom control. Efficiency in diagnosing and treating psychological complications of terminally ill cancer patients may not only improve their quality of life but possibly also prevent long-term psychological morbidity of their surviving partners
Lipidomics: A Tool for Studies of Atherosclerosis
Lipids, abundant constituents of both the vascular plaque and lipoproteins, play a pivotal role in atherosclerosis. Mass spectrometry-based analysis of lipids, called lipidomics, presents a number of opportunities not only for understanding the cellular processes in health and disease but also in enabling personalized medicine. Lipidomics in its most advanced form is able to quantify hundreds of different molecular lipid species with various structural and functional roles. Unraveling this complexity will improve our understanding of diseases such as atherosclerosis at a level of detail not attainable with classical analytical methods. Improved patient selection, biomarkers for gauging treatment efficacy and safety, and translational models will be facilitated by the lipidomic deliverables. Importantly, lipid-based biomarkers and targets should lead the way as we progress toward more specialized therapeutics
How is precision regulated in maintaining trunk posture?
Precision of limb control is associated with increased joint stiffness caused by antagonistic co-activation. The aim of this study was to examine whether this strategy also applies to precision of trunk postural control. To this end, thirteen subjects performed static postural tasks, aiming at a target object with a cursor that responded to 2D trunk angles. By manipulating target dimensions, different levels of precision were imposed in the frontal and sagittal planes. Trunk angle and electromyography (EMG) of abdominal and back muscles were recorded. Repeated measures ANOVAs revealed significant effects of target dimensions on kinematic variability in both movement planes. Specifically, standard deviation (SD) of trunk angle decreased significantly when target size in the same direction decreased, regardless of the precision demands in the other direction. Thus, precision control of trunk posture was directionally specific. However, no consistent effect of precision demands was found on trunk muscle activity, when averaged over time series. Therefore, it was concluded that stiffness regulation by antagonistic co-activation was not used to meet increased precision demands in trunk postural control. Instead, results from additional analyses suggest that precision of trunk angle was controlled in a feedback mode
