Coping Skills for Daily Life: Cost-Effective Strategies to Prevent and Address Mental Health Disorders
Mental health disorders, along with their associated cost and negative outcomes, have continued to persist in Vermont and have become one of the largest, growing challenges to public health in the United States. Unfortunately, Vermont does not appear to have enough resources or providers to optimally address it. Concurrently, coping strategies of minimal cost that have the potential to prevent or address mental health disorders may often be underutilized or misconstrued by the population. A pamphlet providing information on evidenced, cost-effective coping strategies was designed and distributed to providers and patients to enable patients with the skills to help themselves and adapt to their mental health needs, independently.https://scholarworks.uvm.edu/fmclerk/1622/thumbnail.jp
A Test between Plant and Fish Oil Sources: The Potential Benefits of Diet Enhanced with Omega-3 Fatty Acids
Skeletal muscle mediates 70-80% of glucose uptake. When the skeletal muscle’s capability to absorb glucose is reduced, the individual becomes insulin resistant and develops, if unabated, diabetes. Here we performed a high fat feeding study on inbred diet-induced obesity in C57BL/6 (B6) mice over the course of 12 weeks, in which we compared the well-established effects of omega-3 fatty acid (n-3) rich fish oil (FO) versus the poorly understood effects of balanced n-3 and omega-6 fatty acid (n-6) rich plant derived Echium oil (EO). Although there were little differences in HFEO or HFFO supplemented groups compared to the high fat control group with respect to blood glucose or plasma insulin concentrations, the Echium oil-enriched diet improved glucose tolerance by 12 weeks. Skeletal muscle was examined for diet-specific changes in insulin sensitivity, growth and survival signaling, and anti-inflammatory activity. We found that the n-3 supplemented high fat diet-fed mice, and especially the HFEO group, showed enhanced Akt1 activity, as well as increased GSK-3β phosphorylation and inactivation in the HFEO group, suggesting increased insulin signaling and glycogen synthesis. Although skeletal muscle PPARγ levels were not different among the high fat diet groups, BiP, a marker of ER stress, had a trend of being reduced in the HFEO group. Thus, the improved glucose tolerance of Echium oil-supplemented high fat diet-fed mice were due to changes in skeletal muscle physiology resulting in enhanced insulin sensitivity and reduced ER stress
Comparison of automated interval measurements by widely used algorithms in digital electrocardiographs
Background:
Automated measurements of electrocardiographic (ECG) intervals by current-generation digital electrocardiographs are critical to computer-based ECG diagnostic statements, to serial comparison of ECGs, and to epidemiological studies of ECG findings in populations. A previous study demonstrated generally small but often significant systematic differences among 4 algorithms widely used for automated ECG in the United States and that measurement differences could be related to the degree of abnormality of the underlying tracing. Since that publication, some algorithms have been adjusted, whereas other large manufacturers of automated ECGs have asked to participate in an extension of this comparison.
Methods:
Seven widely used automated algorithms for computer-based interpretation participated in this blinded study of 800 digitized ECGs provided by the Cardiac Safety Research Consortium. All tracings were different from the study of 4 algorithms reported in 2014, and the selected population was heavily weighted toward groups with known effects on the QT interval: included were 200 normal subjects, 200 normal subjects receiving moxifloxacin as part of an active control arm of thorough QT studies, 200 subjects with genetically proved long QT syndrome type 1 (LQT1), and 200 subjects with genetically proved long QT syndrome Type 2 (LQT2).
Results:
For the entire population of 800 subjects, pairwise differences between algorithms for each mean interval value were clinically small, even where statistically significant, ranging from 0.2 to 3.6 milliseconds for the PR interval, 0.1 to 8.1 milliseconds for QRS duration, and 0.1 to 9.3 milliseconds for QT interval. The mean value of all paired differences among algorithms was higher in the long QT groups than in normals for both QRS duration and QT intervals. Differences in mean QRS duration ranged from 0.2 to 13.3 milliseconds in the LQT1 subjects and from 0.2 to 11.0 milliseconds in the LQT2 subjects. Differences in measured QT duration (not corrected for heart rate) ranged from 0.2 to 10.5 milliseconds in the LQT1 subjects and from 0.9 to 12.8 milliseconds in the LQT2 subjects.
Conclusions:
Among current-generation computer-based electrocardiographs, clinically small but statistically significant differences exist between ECG interval measurements by individual algorithms. Measurement differences between algorithms for QRS duration and for QT interval are larger in long QT interval subjects than in normal subjects. Comparisons of population study norms should be aware of small systematic differences in interval measurements due to different algorithm methodologies, within-individual interval measurement comparisons should use comparable methods, and further attempts to harmonize interval measurement methodologies are warranted
Dairying, diseases and the evolution of lactase persistence in Europe
Update notice Author Correction: Dairying, diseases and the evolution of lactase persistence in Europe (Nature, (2022), 608, 7922, (336-345), 10.1038/s41586-022-05010-7) Nature, Volume 609, Issue 7927, Pages E9, 15 September 2022In European and many African, Middle Eastern and southern Asian populations, lactase persistence (LP) is the most strongly selected monogenic trait to have evolved over the past 10,000 years(1). Although the selection of LP and the consumption of prehistoric milk must be linked, considerable uncertainty remains concerning their spatiotemporal configuration and specific interactions(2,3). Here we provide detailed distributions of milk exploitation across Europe over the past 9,000 years using around 7,000 pottery fat residues from more than 550 archaeological sites. European milk use was widespread from the Neolithic period onwards but varied spatially and temporally in intensity. Notably, LP selection varying with levels of prehistoric milk exploitation is no better at explaining LP allele frequency trajectoriesthan uniform selection since the Neolithic period. In the UK Biobank(4,5) cohort of 500,000 contemporary Europeans, LP genotype was only weakly associated with milk consumption and did not show consistent associations with improved fitness or health indicators. This suggests that other reasons for the beneficial effects of LP should be considered for its rapid frequency increase. We propose that lactase non-persistent individuals consumed milk when it became available but, under conditions of famine and/or increased pathogen exposure, this was disadvantageous, driving LP selection in prehistoric Europe. Comparison of model likelihoods indicates that population fluctuations, settlement density and wild animal exploitation-proxies for these drivers-provide better explanations of LP selection than the extent of milk exploitation. These findings offer new perspectives on prehistoric milk exploitation and LP evolution.Peer reviewe
The Comparison of Physician to Computer Interpreted Electrocardiograms on ST-elevation Myocardial Infarction Door-to-balloon Times
OBJECTIVE: The purpose of the project was to study the impact that immediate physician electrocardiogram (ECG) interpretation would have on door-to-balloon times in ST-elevation myocardial infarction (STEMI) as compared with computer-interpreted ECGs.
METHODS: This was a retrospective cohort study of 340 consecutive patients from September 2003 to December 2009 with STEMI who underwent emergent cardiac catheterization and percutaneous coronary intervention. Patients were stratified into 2 groups based on the computer-interpreted ECG interpretation: those with acute myocardial infarction identified by the computer interpretation and those not identified as acute myocardial infarction. Patients (n = 173) from September 2003 to June 2006 had their initial ECG reviewed by the triage nurse, while patients from July 2006 to December 2009 (n = 167) had their ECG reviewed by the emergency department physician within 10 minutes. Times for catheterization laboratory activation and percutaneous coronary intervention were recorded in all patients.
RESULTS: Of the 340 patients with confirmed STEMI, 102 (30%) patients were not identified by computer interpretation. Comparing the prior protocol of computer ECG to physician interpretation, the latter resulted in significant improvements in median catheterization laboratory activation time {19 minutes [interquartile range (IQR): 10-37] vs. 16 minutes [IQR: 8-29]; P \u3c 0.029} and in median door-to-balloon time [113 minutes (IQR: 86-143) vs. 85 minutes (IQR: 62-106); P \u3c 0.001].
CONCLUSION: The computer-interpreted ECG failed to identify a significant number of patients with STEMI. The immediate review of ECGs by an emergency physician led to faster activation of the catheterization laboratory, and door-to-balloon times in patients with STEMI
