Sensitivity Limits for ELISA Measurements of Molecular Biomarker Concentrations.

The extremely high sensitivity that has been suggested for magnetic particle imaging has its roots in the unique signal produced by the nanoparticles at the frequencies of the harmonics of the drive field. That sensitivity should be translatable to other methods that utilize magnetic nanoparticle probes, specifically towards magnetic nanoparticle spectroscopy that is used to measure molecular biomarker concentrations for an " ELISA" assay approach. In this paper, we translate the predicted sensitivity of magnetic particle imaging into a projected sensitivity limit for ELISA.

An RCT of Effects of Telephone Care Management on Treatment Adherence and Clinical Outcomes Among Veterans With PTSD.

Objective: This study assessed whether adding telephone care management to usual outpatient mental health care improved treatment attendance, medication compliance, and clinical outcomes of veterans with posttraumatic stress disorder (PTSD).

Methods: In a multisite randomized controlled trial, 358 veterans were assigned to either usual outpatient mental health treatment (N=165) or usual care plus twice-a-month telephone care management (TCM) and support in the first three months of treatment (N=193). Treatment utilization and medication refills were determined from U.

SQUIRE 2.0 (Standards for QUality Improvement Reporting Excellence): Revised Publication Guidelines from a Detailed Consensus Process.

Since the publication of Standards for Quality Improvement Reporting Excellence (SQUIRE 1.0) guidelines in 2008, the science of the field has advanced considerably. In this manuscript we describe the development of SQUIRE 2.

Using the WHODAS 2.0 to Assess Functioning Among Veterans Seeking Compensation for Posttraumatic Stress Disorder.

Objective: One of the major changes in DSM-5 was removal of the Global Assessment of Functioning (GAF). To determine whether the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.

Electron spin resonance microscopic imaging of oxygen concentration in cancer spheroids.

Oxygen (O2) plays a central role in most living organisms. The concentration of O2 is important in physiology and pathology. Despite the importance of accurate knowledge of the O2 levels, there is very limited capability to measure with high spatial resolution its distribution in millimeter-scale live biological samples.

Colonoscopy: quality indicators.

Effective endoscopic screening for colorectal cancer (CRC), one of the few preventable cancers, is dependent on the adequate detection and removal of potentially precancerous lesions. However, observed variation in colonoscopy performance in practice and outcomes has highlighted the need for consistent quality measures. Quality indicators or measures are tools that help to quantify health-care processes and can aid in providing high-quality health care.

Pathogenesis and management of serrated polyps: current status and future directions.

Hyperplastic or serrated polyps were once believed to have little to no clinical significance. A subset of these polyps are now considered to be precursors to colorectal cancers (CRC) in the serrated pathway that may account for at least 15% of all tumors. The serrated pathway is distinct from the two other CRC pathways and involves an epigenetic hypermethylation mechanism of CpG islands within promoter regions of tumor suppressor genes.

Asleep versus awake: does it matter?: Pediatric regional block complications by patient state: a report from the Pediatric Regional Anesthesia Network.

Background And Objectives: The impact of the patient state at time of placement of regional blocks on the risk of complications is unknown. Current opinion is based almost entirely on case reports, despite considerable interest in the question. Analyzing more than 50,000 pediatric regional anesthesia blocks from an observational prospective database, we determined the rate of adverse events in relation to the patient's state at the time of block placement.

Navigating conflicts of interest for the medical device entrepreneur.

The past fifty years has witnessed dramatic progress in the understanding and treatment of patients suffering from cardiovascular disease leading to symptomatic relief and impressive increases in longevity. These advances have been due in large part to the development, study and implementation of new technology. Within interventional cardiology in particular, these advances have been driven by the availability of new technology in the form of medical devices.
