Epigenetic Inheritance and Transgenerational Environmental Justice.

Many chemicals and toxicants are released into our ecosystem and environment every day, which can cause harmful effects on human populations. Agricultural compounds are used in most crop production and have been shown to cause negative health impacts, including effects on reproduction and other pathologies. Although these chemicals can be helpful for pest and weed control, the compounds indirectly impact humans. Several compounds have been banned in the European Union but continue to be used in the United States. Recent work has shown most toxicants affect transgenerational generations more than the directly exposed generations through epigenetic inheritance. While some toxicants do not impact the directly exposed generation, the later generations that are transgenerational or ancestrally exposed suffer health impacts. Due to impacts to future generations, exposure becomes an environmental justice concern. The term "environmental justice" denotes the application of fair strategies when resolving unjust environmental contamination. Fair treatment means that no group should bear a disproportionate share of negative environmental consequences resulting from industrial, municipal, and commercial operations. This article illustrates how research on directly exposed generations is often prioritized over studies on transgenerational generations. However, research on the latter generations suggests the need to take environmental justice concerns seriously moving forward, as future generations could be unduly shouldering harms, while not enjoying benefits of production.

A Survey of Dermatologists' Preparedness for Natural and Manmade Disasters

Natural and manmade disasters cause a range of dermatologic manifestations, including secondary infections after a flood,1 irritation from blistering agents used in chemical warfare,2 or acute and chronic effects of cutaneous radiation syndrome.3 Recognizing and managing these disaster sequelae require diagnostic acumen, knowledge on reporting, and short- and long-term management strategies. However, a 2003 survey revealed that 88% of dermatologists felt unprepared to respond to a biological attack.4

The utility of the triage electrocardiogram for the detection of ST-segment elevation myocardial infarction.

INTRODUCTION: Current AHA/ACC guidelines on the management of ST-elevation myocardial infarction (STEMI) suggest that an ECG is indicated within 10minutes of arrival for patients arriving to the Emergency Department (ED) with symptoms concerning for STEMI. In response, there has been a creep towards performing ECGs more frequently in triage. The objectives of this study were to quantify the number of triage ECGs performed at our institution, assess the proportion of ECGs performed within current hospital guidelines, and evaluate the rate of STEMI detection in triage ECGs. METHODS: A retrospective chart review of all emergency department patients presenting over a period of 8days who had a triage ECG performed. Cases of bradycardia or tachycardia were excluded. Data collection included patient demographics, presenting complaint, cardiac risk factors, troponin values, and final diagnosis. Summary statistics are reported in a descriptive manner. RESULTS: During the study period, 538 patients had a triage ECG for possible STEMI with no STEMI identified and 16 NSTEMI diagnoses (confirmed as positive troponins following ED assessment). Sixty-three (11.7%) patients did not meet internal criteria for a triage ECG. A NSTEMI ED diagnosis was identified in 3% of patients who met internal triage ECG criteria and 1.6% who did not meet criteria (p=0.29). A cost analysis was performed using an average of 50 STEMI cases diagnosed in our ED per given year. Current institutional ECG billing rates for ECGs performed and interpreted is $125 per ECG, providing an estimated triage ECG charge to detect one STEMI at $54,295. DISCUSSION: This retrospective study of 538 triage ECG's performed over an 8day period identified no STEMIs and 16 NSTEMIs. A very large number of ECGs were done at triage overall and included patients who do not meet our own hospital criteria. Given the extremely low yield and high associated charges, current guidelines for triage ECG for identifying a possible STEMI should be reviewed.

Disaster healthcare disparities solutions: Part 3-Recovery and mitigation.

The purpose of this study was to explore the potential solutions for disaster healthcare disparities. This paper is the third of a three-part series that was written by the Disaster Healthcare Disparities Workgroup of the American College of Emergency Physicians Disaster Preparedness and Response Committee. The committee conducted a literature review and chose articles most representative and demonstrative of solutions to disaster healthcare disparities found in a past workgroup product. Many solutions for disaster healthcare disparities seen during recovery and mitigation were found. Some of these solutions have been successfully implemented and some remain theoretical. Solutions for disaster healthcare disparities seen during recovery and mitigation are achievable but there is still much work to do. Many of these solutions can be advocated for by nondisaster specialists.

Disparities in disaster healthcare: A review of past disasters.

OBJECTIVE: To review the literature on the effects seen after disaster on those with poor social determinants of health (SDOH) and individual social needs. DESIGN: The Disaster Preparedness and Response Committee of the American College of Emergency Physicians (ACEP) formed a work group to study healthcare disparities seen in disaster. This group was composed of six physicians on the committee, all of whom have extensive background in disaster medicine and the chair of the committee. A systematic literature review regarding past disasters and all the healthcare disparities seen was undertaken with the goal of organizing this information in one broad concise document looking at multiple disasters over history. The group reviewed multiple documents regarding SDOH and individual social needs for a complete understanding of these factors. Then, a topic list of healthcare disparities resulting from these factors was composed. This list was then filled out with subtopics falling under the header topics. Each member of the workgroup took one of these topics of healthcare disparity seen in disasters and completed a literature search. The databases reviewed include PubMed Central, Google Scholar, and Medline. The terms queried were disaster, healthcare disparities, disaster healthcare disparities, healthcare disparities associated with disasters, SDOH and disaster, special populations and disaster effects, and vulnerable populations and disaster effects. Each author chose articles they felt were most representative and demonstrative of the healthcare disparities seen in past disasters. These social determinant factors and individual social needs were then cross referenced in relation to past disasters for both their causes and the effect they had on various populations after disaster. This was presented to the ACEP board as a committee report. RESULTS: All the SDOH and individual social needs showed significant negative effects for the populations when combined with a disaster event. These SDOH cut across age, race, and gender affecting a wide swath of people. Previous disaster planning either did not plan or under planned for these marginalized populations during disaster events. CONCLUSIONS: Disparities in healthcare are a pervasive problem that effects many different groups. Disasters magnify and more fully expose these healthcare disparities. We have explored the healthcare disparities with past disasters. These disparities, although common, can be mitigated. The recognition of these poor determinants of health can lead to better and more comprehensive disaster planning for future disasters. Subsequent research is needed to explore these healthcare disparities exacerbated by disasters and to find methods for their mitigation.

Operation Navajeevan: A Public-Private Partnership Model for Disaster Relief in Kozhikode, India.

INTRODUCTION: In August 2018, India's southern state of Kerala experienced its worst flooding in over a century. This report describes the relief efforts in Kozhikode, a coastal region of Kerala, where Operation Navajeevan was initiated. SOURCES: Data were collected from a centralized database at the command center in the District Medical Office as well as first-hand accounts from providers who participated in the relief effort. OBSERVATIONS: From August 15 through September 8, 2018, 36,846 flood victims were seen at 280 relief camps. The most common cause for presentation was exacerbation of an on-going chronic medical condition (18,490; 50.2%). Other common presentations included acute respiratory infection (7,451; 20.2%), traumatic injuries (3,736; 10.4%), and psychiatric illness (5,327; 14.5%). ANALYSIS: The prevalence of chronic disease exacerbation as the primary presentation during Operation Navajeevan represents an epidemiologic shift in disaster relief in India. It is foreseeable that as access to health care improves in low- and middle-income countries (LMICs), and climate change increases the prevalence of extreme weather events around the world, that this trend will continue.

Henry Ford HEART Score Randomized Trial: Rapid Discharge of Patients Evaluated for Possible Myocardial Infarction.

BACKGROUND: Hospital evaluation of patients with chest pain is common and costly. The HEART score risk stratification tool that merges troponin testing into a clinical risk model for evaluation emergency department patients with possible acute myocardial infarction (AMI) has been shown to effectively identify a substantial low-risk subset of patients possibly safe for early discharge without stress testing, a strategy that could have tremendous healthcare savings implications. METHOD AND RESULTS: A total of 105 patients evaluated for AMI in the emergency departments of 2 teaching hospitals in the Henry Ford Health System (Detroit and West Bloomfield, MI), between February 2014 and May 2015, with a modified HEART score ≤3 (which includes cardiac troponin I <0.04 ng/mL at 0 and 3 hours) were randomized to immediate discharge (n=53) versus management in an observation unit with stress testing (n=52). The primary end points were 30-day total charges and length of stay. Secondary end points were all-cause death, nonfatal AMI, rehospitalization for evaluation of possible AMI, and coronary revascularization at 30 days. Patients randomized to early discharge, compared with those who were admitted for observation and cardiac testing, spent less time in the hospital (median 6.3 hours versus 25.9 hours; P<0.001) with an associated reduction in median total charges of care ($2953 versus $9616; P<0.001). There were no deaths, AMIs, or coronary revascularizations in either group. One patient in each group was lost to follow-up. CONCLUSIONS: Among patients evaluated for possible AMI in the emergency department with a modified HEART score ≤3, early discharge without stress testing as compared with transfer to an observation unit for stress testing was associated with significant reductions in length of stay and total charges, a finding that has tremendous potential national healthcare expenditure implications.

Impact of a Simulation-Based Communication Workshop on Resident Preparedness for End-of-Life Communication in the Intensive Care Unit.

Introduction. Although residents frequently lead end-of-life (EOL) discussions in the intensive care unit (ICU), training in EOL care during residency has been required only recently, and few educational interventions target EOL communication in the ICU. This study evaluated a simulation-based intervention designed to improve resident EOL communication skills with families in the ICU. Methods. Thirty-four second-year internal medicine residents at a large urban teaching hospital participated in small group sessions with faculty trained in the "VitalTalk" method. A Likert-type scale questionnaire measured self-assessed preparedness before, immediately following, and approximately 9 months after intervention. Data were analyzed using Wilcoxon rank-sum analysis. Results. Self-assessed preparedness significantly improved for all categories surveyed (preintervention mean; postintervention mean; p value), including discussing bad news (3.3; 4.2; p < 0.01), conducting a family conference (3.1; 4.1; p < 0.01), discussing treatment options (3.2; 3.9; p < 0.01), discussing discontinuing ICU treatments (2.9; 3.5; p < 0.01), and expressing empathy (3.9; 4.5; p < 0.01). Improvement persisted at follow-up for all items except "expressing empathy." Residents rated the educational quality highly. Conclusion. This study provides evidence that brief simulation-based interventions can produce lasting improvements in residents' confidence to discuss EOL care with family members of patients in the ICU.

Labeling, stability and biodistribution studies of 99mTc-cyclized Tyr3-octreotate derivatives.

INTRODUCTION: To probe the interplay between radiotracer stability and somatostatin receptor affinity, Tyr(3)-octreotate and six variations of its peptide sequence, for which the Re-cyclized products were previously reported, were radiolabeled with (99m)Tc and investigated for their in vitro stability. METHODS: Radiolabeling of the peptides was effected by ligand exchange from (99m)Tc-glucoheptonate, and the desired products were purified by radio-RP-HPLC. The in vitro stability in phosphate buffered saline, mouse serum and cysteine solutions at physiological temperature and pH for all seven (99m)Tc-cyclized peptides was determined by radio-RP-HPLC and radio-TLC. Normal CF-1 mouse biodistribution studies were performed for three of the (99m)Tc-cyclized peptides. RESULTS: Based on the fully characterized Re-cyclized peptide analogues, four (99m)Tc-coordination motifs were proposed for the (99m)Tc-cyclized peptides. Technetium-99m-cyclized Tyr(3)-octreotate derivatives with N(2)S(2) metal coordination modes and large metal ring sizes were susceptible to oxidation and loss of (99m)Tc in the form of (99m)TcO(4)(-), as evidenced by their instability in the various solutions under physiological conditions (15-58% intact at 24 h). As anticipated, the addition of a third cysteine to the sequence stabilized the (99m)Tc metal coordination, and peptides with NS(3) coordination modes remained >85% intact out to 24 h. No significant differences were observed in the biodistribution studies performed with three peptides of varying stabilities. CONCLUSIONS: Improvements in stability were not sufficient to outweigh the low somatostatin receptor affinity for the peptides in this study. Further improvements in the peptide sequence and/or metal coordination are needed to result in a radiodiagnostic/radiotherapeutic pair for targeting the somatostatin receptor.
