Background: Little has been published on the practice of echocardiography (echo) in the United States. We used the Intersocietal Accreditation Commission-Echocardiography (IAC-Echo) applications database to describe the personnel in echo laboratories seeking accreditation. Methods: We used de-identified data provided on IAC-Echo applications to characterize facilities by hospital association, census region, annual volume, number of sites, previous accreditation, and numbers of physicians and sonographers as well as National Board of Echocardiography (NBE) testamur status of physicians and registered credential status of sonographers. We categorized Medical Directors by board certification in cardiovascular diseases, internal medicine, other specialty, or none. Medical Director echo training could be formal Level 2 or 3 or experiential by ≥3 years of practice. Frequencies, means, and medians were compared between groups using the chi-square test, t-test, or Mann Whitney test, respectively. Results: From 2011 to 2013, 1926 echo labs representing 10618 physicians and 6870 sonographers applied for IAC-Echo accreditation or re-accreditation. The majority of medical directors were board certified in cardiovascular diseases and 34.1% of medical directors and 27.2% of staff physicians held NBE testamur status; 79.5% of sonographers held registered credentials. Most echo labs were in the Northeast or South census regions, have an average of 1.75 sites, and are based outside of hospitals (Table). Compared to nonhospital echo labs, medical directors of hospital-based echo labs were more likely to be Level 3 trained (19.8% versus 30.8%, p<0.01) and be NBE testamurs (28.9% versus 45.6%, p<0.01). Markers of echo lab size, region, previous accreditation, and credentialed sonographers were associated with accreditation versus delay decisions; there was a trend toward accreditation among facilities with NBE medical directors. Conclusion: Among facilities seeking IAC-Echo accreditation, the minority of echo physicians hold NBE testamur status. Hospital and nonhospital facilities are different in the credentials of their personnel.

AbstractThirty-five species of lichens were collected from nine locations on or adjacent to the Navajo Indian Reservation in the southwestern United States. Wool was dyed using the traditional boiling water and ammonia fermentation methods. An additional method was developed using a solvent to extract lichen substances and dye wool, cold; this dimethylsulphoxide extraction method is described and the resulting dye colours were sometimes different. Over 155 individual dye tests were made on sheep's wool; a correlation of dye colour with lichen substances reported for the species was attempted. Predominant dye colours were tan, but yellow, orange, pink, purple, and blue-grey were also produced. These colours were further altered by modifying: (1) fermentation time; (2) dyeing time, temperature, or pH level; (3) exposure to light; and (4) subsequent additional extractions using the same method or different methods. Dyed wool samples, tested for stability in sunlight, generally faded to some degree and some changed colour. Most dyes obtained through the dimethylsulphoxide extraction method were light stable.

Biosafety Level

AbstractRegulations in the United States require animal biosafety level 3 (ABSL-3) or biosafety level 3 agriculture (BSL-3-Ag) containment for many endemic zoonotic pathogens and etiologic agents of foreign animal diseases. In an effort to protect public health, billions of dollars were invested in regulatory programs over many years to reduce the prevalence of zoonotic pathogens such as Brucella and Mycobacterium bovis in domestic livestock. In addition to research needs in domestic livestock hosts, the establishment of brucellosis and tuberculosis in wildlife in the United States has created a need for research studies addressing these zoonotic diseases. As guidelines in the Biosafety in Microbiological and Biomedical Laboratories (BMBL, 2009) for BSL-3 and BSL-3-Ag facilities are primarily directed toward laboratory or vivarium facilities, additional issues should be considered in designing large animal containment facilities for domestic livestock and/or wildlife. Flight distance, herd orientation, social needs, aggressiveness, and predictability are all factors we considered on a species by species basis for designing our containment facilities and for work practices with large ruminants. Although safety risk cannot be completely eliminated when working with large animals, studies in natural hosts are critical for advancing vaccine and diagnostic development, and providing basic knowledge of disease pathogenesis in natural hosts. Data gathered in these types of studies are vital for state and national regulatory personnel in their efforts to design strategies to control or eradicate diseases such as brucellosis and tuberculosis in their natural hosts, whether it is domestic livestock or wildlife. It is likely that failure to address the prevalence of disease in wildlife reservoirs will lead to re-emergence in domestic livestock. The overall benefit of these studies is to protect public health, provide economic benefits to producers, and protect the economic investment made in regulatory programs.

Wheat blast, caused by the Triticum pathotype of Magnaporthe oryzae, poses a significant threat to wheat production worldwide. Because this pathotype does not occur in the United States, it is important to prepare for its possible introduction. As part of this preparation, over 500 U.S. wheat cultivars were tested for susceptibility or resistance to head blast. Inoculations were conducted under biosafety level 3 conditions. However, the protocols to phenotype wheat cultivars vary among researchers, and head blast inoculation protocols need to be standardized so that results can be easily interpreted and shared internationally. The protocol presented, based on several years' experience, is recommended for common use to facilitate direct comparison of disease phenotyping results among researchers.

War Protest

The reaction to the Vietnam War protest years, the presidency of Richard Nixon, and ultimately that of Ronald Reagan, ushered in a conservative revolution in the United States that still endures. Republican Presidents during this period have appointed eleven Justices to the United States Supreme Court,1 seven of whom serve on the Court today.2 Coinciding with this historical phenomenon was the proliferation of drug usage in the country: first marijuana, hallucinogenic drugs, and amphetamines during the counterculture years of the late ’60s and ’70s, and later powder and then crack cocaine. When prosecutorial emphasis shifted, especially at the federal level,3 to meet the increased fascination with narcotics, courts in the country became deluged with drug cases, many if not most of which presented Fourth Amendment search and seizure issues. This, of course, was because the Fourth Amendment’s exclusionary rule could make the corpus of the crime unavailable to the prosecution.

Adverse Medical Events

Context: With the increasing use of unregulated dietary supplements, athletes are at continued risk from adverse medical events and inadvertent doping. Evidence Acquisition: A review of Clinical Key, MEDLINE, and PubMed databases from 2012 to 2017 was performed using search terms, including dietary supplement, contamination, doping in athletes, inadvertent doping, and prohibited substances. The references of pertinent articles were reviewed for other relevant sources. Study Design: Clinical review. Level of Evidence: Level 3. Results: Poor manufacturing processes and intentional contamination with many banned substances continue to occur in dietary supplements sold in the United States. Certain sectors, such as weight loss and muscle-building supplements, pose a greater threat because they are more likely to be contaminated. Conclusion: Athletes will continue to be at risk for adverse events and failed doping tests due to contaminated dietary supplements until legislation changes how they are regulated. In the interim, there are several steps that can be taken to mitigate this risk, including improved education of medical staff and athletes and use of third party–certified products.

Drug Resistant Epilepsy

Background and Objectives:Patients with drug resistant epilepsy (DRE) may benefit from specialized testing and treatments to better control seizures and improve quality of life. Most evaluations and procedures for DRE in the United States are performed at epilepsy centers accredited by the National Association of Epilepsy Centers (NAEC). On an annual basis, the NAEC collects data from accredited epilepsy centers on hospital-based epilepsy monitoring unit (EMU) size and admissions, diagnostic testing, surgeries, and other services. This article highlights trends in epilepsy center services from 2012 through 2019.Methods:We analyzed data reported in 2012, 2016, and 2019 from all level 3 and level 4 NAEC accredited epilepsy centers. Data were described using frequency for categorical variables and median for continuous variables and were analyzed by center level and center population category. EMU beds, EMU admissions, epileptologists, and aggregate procedure volumes were also described using rates per population per year.Results:During the period studied, the number of NAEC accredited centers increased from 161 to 256, with the largest increases in adult- and pediatric-only centers. Growth in EMU admissions (41%), EMU beds (26%), and epileptologists (109%) per population occurred. Access to specialized testing and services broadly expanded. The largest growth in procedure volumes occurred in laser interstitial thermal therapy (LiTT) (61%), responsive neurostimulation (RNS) implantations (114%) and intracranial monitoring without resection (152%) over the study period. Corpus callosotomies and vagus nerve stimulator (VNS) implantations decreased (-12.8% and -2.4% respectively), while growth in temporal lobectomies (5.9%), extratemporal resections (11.9%), and hemispherectomies/otomies (13.1%) lagged center growth (59%), leading to a decrease in median volumes of these procedures per center.Discussion:During the study period, the availability of specialty epilepsy care in the U.S. improved as the NAEC implemented its accreditation program. Surgical case complexity increased while aggregate surgical volume remained stable or declined across most procedure types, with a corresponding decline in cases per center. This article describes recent data trends and current state of resources and practice across NAEC member centers and identifies several future directions for driving systematic improvements in epilepsy care.
