Spectral Data Fusion From Handheld Laser-Induced Breakdown Spectroscopy (LIBS) and X-ray Fluorescence (XRF) Analyzers for Improved Detection of Cerium in a Simulated Dispersal Accident.

This work implements a mid-level data fusion methodology on spectral data from handheld X-ray fluorescence and laser-induced breakdown spectroscopy analyzers to quantify plutonium surrogate (CeO) contamination in soil samples for the first time. Spectral data from each analyzer were used independently to train supervised machine learning regressions to predict Ce concentration. Fused features from both data sets were then used to train the same models, comparing prediction performance by evaluating model precision and sensitivity.

Home Birth in the United States: An Evidence-Based Ethical Analysis.

AbstractThe assumption in current U.S. mainstream medicine is that birthing requires hospitalization.

Opioid-Related Genetic Polymorphisms of Cytochrome P450 Enzymes after Total Joint Arthroplasty: A Focus on Drug-Drug-Gene Interaction with Commonly Coprescribed Medications.

Pharmacogenomic testing, together with the early detection of drug-drug-gene interactions (DDGI) before initiating opioids, can improve the selection of dosage and reduce the risk of adverse drug interactions and therapeutic failures following Total Joint Arthroplasty. The variants of CYP genes can mediate DDGI. Orthopedic surgeons should become familiar with the genetic aspect of opioid use and abuse, as well as the influence of the patient genetic makeup in opioid selection and response, and polymorphic variants in pain modulation.

Opioid receptor system contributes to the acute and sustained antidepressant-like effects, but not the hyperactivity motor effects of ketamine in mice.

In 2000, a subanesthetic dose (0.5 mg/kg i.v.

The Relationship Between Patient Satisfaction With Hospitalization and Outcomes Up to 6 Months Post-Discharge in Cardiac Patients.

Little is known about the relationship between patient satisfaction with inpatient care and post-discharge outcomes. This study examined inpatient hospital satisfaction after a cardiac event and outcomes through 6 months post-discharge. We examined 327 cardiac patients from the Bridging the Discharge Gap Effectively database who completed a patient satisfaction survey about their hospital admission and had post-discharge outcomes data.

Fighting Fire with Fire: Phage Potential for the Treatment of O157 Infection.

Hemolytic⁻uremic syndrome is a life-threating disease most often associated with Shiga toxin-producing microorganisms like (STEC), including O157:H7. Shiga toxin is encoded by resident prophages present within this bacterium, and both its production and release depend on the induction of Shiga toxin-encoding prophages. Consequently, treatment of STEC infections tend to be largely supportive rather than antibacterial, in part due to concerns about exacerbating such prophage induction.

Mindfulness for Healthcare Providers: The Role of Non-Reactivity in Reducing Stress.

Context: There is strong evidence in the literature that the cultivation of mindfulness through programs such as Mindfulness-Based Stress Reduction (MBSR) has a profound impact on perceived stress for healthcare providers. The mechanism of the latter association is still being studied. However, it has been hypothesized that in particular, the cultivation of non-reactivity as a mindfulness skill may be particularly associated with the salutary effect of MBSR to reduce stress in health care providers even if adjusted for the benefit on quality of life gained after MBSR.

Bridging the gap between physician and medical student education: using the Train the Trainer model to improve cultural competence training in the clerkship years of medical school.

Cultural competence (CC) training has become a required part of medical education to create future physicians dedicated to decreasing health disparities. However, current training seems to be inadequate as research has demonstrated gaps between CC training and clinical behaviors of students. One aspect that is potentially contributing to this gap is the lack of physician education of CC.

Cross-sectional association of physical activity and periodontal antibodies.

Background: The objective of this study was to evaluate the cross-sectional association between physical activity and serum IgG antibodies against selected periodontal microorganisms.

Methods: The study population consisted of 5,611 randomly selected US adults who participated in the National Health and Nutrition Examination Survey (NHANES) III (1988 to 1994), who were 40 years and older with complete IgG antibody data against 19 oral microorganisms. We used cluster analysis to classify the 19 antibody titers into 4 mutually exclusive groups called "Orange-Red," "Red-Green," "Yellow- Orange," and "Orange-Blue," and calculated cluster scores by summing antibody titer z-scores for each of the four groups.

Development and Feasibility of a Home Pulmonary Rehabilitation Program With Health Coaching.

Background: Pulmonary rehabilitation (PR) is an effective intervention for COPD. However, traditional center-based PR programs suffer from low uptake. Home-based PR is a viable solution, but few studies have shown the effectiveness of remote PR, as there is a scarcity of systems that can be easily adopted in clinical practice.

A method for multiplex gene synthesis employing error correction based on expression.

Our ability to engineer organisms with new biosynthetic pathways and genetic circuits is limited by the availability of protein characterization data and the cost of synthetic DNA. With new tools for reading and writing DNA, there are opportunities for scalable assays that more efficiently and cost effectively mine for biochemical protein characteristics. To that end, we have developed the Multiplex Library Synthesis and Expression Correction (MuLSEC) method for rapid assembly, error correction, and expression characterization of many genes as a pooled library.

Characterization of missing human genome sequences and copy-number polymorphic insertions.

The extent of human genomic structural variation suggests that there must be portions of the genome yet to be discovered, annotated and characterized at the sequence level. We present a resource and analysis of 2,363 new insertion sequences corresponding to 720 genomic loci. We found that a substantial fraction of these sequences are either missing, fragmented or misassigned when compared to recent de novo sequence assemblies from short-read next-generation sequence data.
