Extracorporeal cardiopulmonary resuscitation dissemination and integration with organ preservation in the USA: ethical and logistical considerations.

Use of extracorporeal membrane oxygenation (ECMO) in cardiopulmonary resuscitation, termed eCPR, offers the prospect of improving survival with good neurological function after cardiac arrest. After death, ECMO can also be used for enhanced preservation of abdominal and thoracic organs, designated normothermic regional perfusion (NRP), before organ recovery for transplantation. To optimize resuscitation and transplantation outcomes, healthcare networks in Portugal and Italy have developed cardiac arrest protocols that integrate use of eCPR with NRP. Similar dissemination of eCPR and its integration with NRP in the USA raise novel ethical issues due to a non-nationalized health system and an opt-in framework for organ donation, as well as other legal and cultural factors. Nonetheless, eCPR investigations are ongoing, and both eCPR and NRP are selectively employed in clinical practice. This paper delineates the most pressing relevant ethical considerations and proposes recommendations for implementation of protocols that aim to promote public trust and reduce conflicts of interest. Transparent policies should rely on protocols that separate lifesaving from organ preservation considerations; robust, centralized eCPR data to inform equitable and evidence-based allocations; uniform practices concerning clinical decision-making and resource utilization; and partnership with community stakeholders, allowing patients to make decisions about emergency care that align with their values. Proactively addressing these ethical and logistical challenges could enable eCPR dissemination and integration with NRP protocols in the USA, with the potential to maximize lives saved through both improved resuscitation with good neurological outcomes and increased organ donation opportunities when resuscitation is unsuccessful or not in accordance with individuals' wishes.

T1 and T2 quantification using magnetic resonance fingerprinting in mild traumatic brain injury.

OBJECTIVES: To assess whether MR fingerprinting (MRF)-based relaxation properties exhibit cross-sectional and prospective correlations with patient outcome and compare the results with those from DTI. METHODS: Clinical imaging, MRF, and DTI were acquired in patients (24 ± 10 days after injury (timepoint 1) and 90 ± 17 days after injury (timepoint 2)) and once in controls. Patient outcome was assessed with global functioning, symptom profile, and neuropsychological testing. ADC and fractional anisotropy (FA) from DTI and T1 and T2 from MRF were compared in 12 gray and white matter regions with Mann-Whitney tests. Bivariate associations between MR measures and outcome were assessed using the Spearman correlation and logistic regression. RESULTS: Data from 22 patients (38 ± 12 years; 17 women) and 18 controls (32 ± 8 years; 12 women) were analyzed. Fourteen patients (37 ± 12 years; 11 women) returned for timepoint 2, while two patients provided only timepoint 2 clinical outcome data. At timepoint 1, there were no differences between patients and controls in T1, T2, and ADC, while FA was lower in mTBI frontal white matter. T1 at timepoint 1 and the change in T1 exhibited more (n = 18) moderate to strong correlations (|r|= 0.6-0.85) with clinical outcome at timepoint 2 than T2 (n = 3), FA (n = 7), and ADC (n = 2). High T1 at timepoint 1, and serially increasing T1, accounted for five of the six MR measures with the highest utility for identification of non-recovered patients at timepoint 2 (AUC > 0.80). CONCLUSION: T1 derived from MRF was found to have higher utility than T2, FA, and ADC for predicting 3-month outcome after mTBI. KEY POINTS: • In a region-of-interest approach, FA, ADC, and T1 and T2 all showed limited utility in differentiating patients from controls at an average of 24 and 90 days post-mild traumatic brain injury. • T1 at 24 days, and the serial change in T1, revealed more and stronger predictive correlations with clinical outcome at 90 days than did T2, ADC, or FA. • T1 showed better prospective identification of non-recovered patients at 90 days than ADC, T2, and FA.

Evaluating factors that influenced the successful implementation of an evidence-based neonatal care intervention in Chinese hospitals using the PARIHS framework.

BACKGROUND: Evidence based interventions (EBIs) can improve patient care and outcomes. Understanding the process for successfully introducing and implementing EBIs can inform effective roll-out and scale up. The Promoting Action on Research Implementation in Health Services (PARIHS) framework can be used to evaluate and guide the introduction and implementation of EBIs. In this study, we used kangaroo mother care (KMC) as an example of an evidence-based neonatal intervention recently introduced in selected Chinese hospitals, to identify the factors that influenced its successful implementation. We also explored the utility of the PARIHS framework in China and investigated how important each of its constructs (evidence, context and facilitation) and sub-elements were perceived to be to successful implementation of EBIs in a Chinese setting. METHOD: We conducted clinical observations and semi-structured interviews with 10 physicians and 18 nurses in five tertiary hospitals implementing KMC. Interview questions were organized around issues including knowledge and beliefs, resources, culture, implementation readiness and climate. We used directed content analysis to analyze the interview transcript, amending the PARIHS framework to incorporate emerging sub-themes. We also rated the constructs and sub-elements on a continuum from "low (weak)", "moderate" or "high (strong)" highlighting the ones considered most influential for hospital level implementation by study participants. RESULTS: Using KMC as an example, our finding suggest that clinical experience, culture, leadership, evaluation, and facilitation are highly influential elements for EBI implementation in China. External evidence had a moderate impact, especially in the initial awareness raising stages of implementation and resources were also considered to be of moderate importance, although this may change as implementation progresses. Patient experience was not seen as a driver for implementation at hospital level. CONCLUSION: Based on our findings examining KMC implementation as a case example, the PARIHS framework can be a useful tool for planning and evaluating EBI implementation in China. However, it's sub-elements should be assessed and adapted to the implementation setting.

Targeting versus Tailoring Educational Videos for Encouraging Deceased Organ Donor Registration in Black-Owned Barbershops.

In the U.S., black men are at highest risk for requiring kidney transplants but are among those least likely to register for organ donation. Prior outreach used videos culturally targeted for Black communities, yet registration rates remain insufficient to meet demand. Therefore, we assessed whether generic versus videos culturally targeted or personally tailored based on prior organ donation beliefs differentially increase organ donor registration. In a randomized controlled trial, 1,353 participants in Black-owned barbershops viewed generic, targeted, or tailored videos about organ donation. Logistic regression models assessed the relative impact of videos on: 1) immediate organ donor registration, 2) taking brochures, and 3) change in organ donation willingness stage of change from baseline. Randomization yielded approximately equal groups related to demographics and baseline willingness and beliefs. Neither targeted nor tailored videos differentially affected registration compared with the generic video, but participants in targeted and tailored groups were more likely to take brochures. Targeted (OR = 1.74) and tailored (OR = 1.57) videos were associated with incremental increases in organ donation willingness stage of change compared to the generic video. Distributing culturally targeted and individually tailored videos increased organ donor willingness stage of change among Black men in Black-owned barbershops but was insufficient for encouraging registration.Abbreviations: CI - confidence interval; DMV - Department of Motor Vehicles; BOBs - Black-owned barbershops; ODBI - organ donation belief index; ODWS - organ donation willingness stage of change; OR - odds ratio.

Intracardiac echocardiographic-guided right-sided cardiac biopsy: Case series and literature review.

Endomyocardial biopsy (EMB) is a common procedure used to aid in the diagnosis of diffuse myocardial diseases and, less commonly, in the diagnosis of cardiac tumors. As cardiac tumors are often found in high-risk locations (ventricular free wall or atria), precision biopsy is paramount, and additional imaging, like transesophageal echocardiography is often required for guidance. The use of intracardiac echocardiography (ICE) to guide biopsy has been described, but there is no consensus on a standardized approach. We report our institutional approach with three cases of ICE-directed EMB performed with the 2.4 mm Jawz bioptome directed with an 8.5-Fr Agilis NxT steerable introducer. All cases were performed under guidance with the AcuNav ICE probe. There were no procedural complications and a definitive diagnosis was obtained in all three cases. We also review the available published cases of ICE-guided EMB in the literature-noting the different procedural approaches, complication rate, and diagnostic yield. There were only two negative biopsies reported among the published cases and no reported complications. Our review of all these cases suggests that ICE-guidance for EMB is superior to other forms of imaging in its ease of use and high definition of right-sided cardiac structures. We also feel that the use of the Agilis steerable sheath allows for more precise directing of the bioptome and is a critical component in performing a successful targeted biopsy.

The unique moral permissibility of uncontrolled lung donation after circulatory death.

Implementing uncontrolled donation after circulatory determination of death (uDCDD) in the United States could markedly improve supply of donor lungs for patients in need of transplants. Evidence from US pilot programs suggests families support uDCDD, but only if they are asked permission for using invasive organ preservation procedures prior to initiation. However, non-invasive strategies that confine oxygenation to lungs may be applicable to the overwhelming majority of potential uDCDD donors that have airway devices in place as part of standard resuscitation. We propose an ethical framework for lung uDCDD by: (a) initiating post mortem preservation without requiring prior permission to protect the opportunity for donation until an authorized party can be found; (b) using non-invasive strategies that confine oxygenation to lungs; and (c) maintaining strict separation between the healthcare team and the organ preservation team. Attempting uDCDD in this way has great potential to obtain more transplantable lungs while respecting donor autonomy and family wishes, securing public support, and enabling authorized persons to affirm or cease preservation decisions without requiring evidence of prior organ donation intent. It ensures prioritization of life-saving, the opportunity to allow willing donors to donate, and respect for bodily integrity while adhering to current ethical norms.

Ethical and logistical concerns for establishing NRP-cDCD heart transplantation in the United States.

Controlled heart donation after circulatory determination of death (cDCD) is well established internationally with good outcomes and could be adopted in the United States to increase heart supply if ethical and logistical challenges are comprehensively addressed. The most effective and resource-efficient method for mitigating warm ischemia after circulatory arrest is normothermic regional perfusion (NRP) in situ. This strategy requires restarting circulation after declaration of death according to circulatory criteria, which appears to challenge the legal circulatory death definition requiring irreversible cessation. Permanent cessation for life-saving efforts must be achieved to assuage this concern and ligating principal vessels maintains no blood flow to the brain, which ensures natural progression to cessation of brain function. This practice-standard in some countries-raises unique concerns about prioritizing life-saving efforts, informed authorization from decision-makers, and the clinician's role in the patient's death. To preserve public trust, medical integrity, and respect for the donor, the donation conversation must not take place until after an un-coerced decision to withdraw life-sustaining treatment made in accordance with the patient's treatment goals. The decision-maker(s) must understand cDCD procedure well enough to provide genuine authorization and the preservation/procurement teams must be kept separate from the clinical care team.

Clinical Policy: Critical Issues Related to Opioids in Adult Patients Presenting to the Emergency Department.

This clinical policy from the American College of Emergency Physicians addresses key issues in opioid management in adult patients presenting to the emergency department. A writing subcommittee conducted a systematic review of the literature to derive evidence-based recommendations to answer the following clinical questions: (1) In adult patients experiencing opioid withdrawal, is emergency department-administered buprenorphine as effective for the management of opioid withdrawal compared with alternative management strategies? (2) In adult patients experiencing an acute painful condition, do the benefits of prescribing a short course of opioids on discharge from the emergency department outweigh the potential harms? (3) In adult patients with an acute exacerbation of noncancer chronic pain, do the benefits of prescribing a short course of opioids on discharge from the emergency department outweigh the potential harms? (4) In adult patients with an acute episode of pain being discharged from the emergency department, do the harms of a short concomitant course of opioids and muscle relaxants/sedative-hypnotics outweigh the benefits? Evidence was graded and recommendations were made based on the strength of the available data.

Injuries associated with electric-powered bikes and scooters: analysis of US consumer product data.

BACKGROUND: Powered, two-wheeled transportation devices like electric bicycles (E-bikes) and scooters are increasingly popular, but little is known about their relative injury risk compared to pedal operated bicycles. METHODS: Descriptive and comparative analysis of injury patterns and trends associated with E-bikes, powered scooters and pedal bicycles from 2000 to 2017 using the US National Electronic Injury Surveillance System. RESULTS: While persons injured using E-bikes were more likely to suffer internal injuries (17.1%; 95% CI 5.6 to 28.6) and require hospital admission (OR=2.8, 95% CI 1.3 to 6.1), powered scooter injuries were nearly three times more likely to result in a diagnosis of concussion (3% of scooter injuries vs 0.5% of E-bike injuries). E-bike-related injuries were also more than three times more likely to involve a collision with a pedestrian than either pedal bicycles (OR=3.3, 95% CI 0.5 to 23.6) or powered scooters (OR=3.3, 95% CI 0.3 to 32.9), but there was no evidence that powered scooters were more likely than bicycles to be involved in a collision with a pedestrian (OR=1.0, 95% CI 0.3 to 3.1). While population-based rates of pedal bicycle-related injuries have been decreasing, particularly among children, reported E-bike injuries have been increasing dramatically particularly among older persons. CONCLUSIONS: E-bike and powered scooter use and injury patterns differ from more traditional pedal operated bicycles. Efforts to address injury prevention and control are warranted, and further studies examining demographics and hospital resource utilisation are necessary.

Barriers and facilitators of kangaroo mother care adoption in five Chinese hospitals: a qualitative study.

BACKGROUND: Kangaroo mother care (KMC) has been proved to be a safe and cost-effective standard of care for preterm babies. China hasn't adopted the KMC practice widely until recently. We aim to assess barriers and facilitators of KMC adoption in neonatal intensive care units (NICUs) and postnatal wards in China. METHODS: We conducted clinical observations and semi-structured interviews with nurses, physicians, and parents who performed KMC in seven NICUs and postnatal wards housed in five hospitals in different provinces of China between August and September 2018. The interviews provided first-hand stakeholder perspectives on barriers and facilitators of KMC implementation and sustainability. We further explored health system's readiness and families' willingness to sustain KMC practice following its pilot introduction. We coded data for emerging themes related to financial barriers, parent- and hospital-level perceived barriers, and facilitators of KMC adoption, specifically those unique in the Chinese context. RESULTS: Five hospitals with KMC pilot programs were selected for clinical observations and 38 semi-structured interviews were conducted. Common cultural barriers included concerns with the conflict with traditional postpartum confinement (Zuo-yue-zi) practice and grandparents' resistance, while a strong family support is a facilitator for KMC adoption. Some parents reported anxiety and guilt associated with having a preterm baby, which can be a parental-level barrier to KMC. Hospital-level factors such as fear of nosocomial infection and shortage of staff and spaces impeded the KMC implementation, and supportive community and peer group organized by the hospital contributed to KMC uptake. Financial barriers included lodging costs for caregivers and supply costs for hospitals. CONCLUSIONS: We provided a comprehensive in-depth report on the multi-level KMC barriers and facilitators in China. We recommend policy interventions specifically addressing these barriers and facilitators and increase family and peer support to improve KMC adoption in China. We also recommend that well-designed local cultural and economic feasibility and acceptability studies should be conducted before the KMC uptake.

Operationalising health systems thinking: a pathway to high effective coverage.

BACKGROUND: The global health community has recognised the importance of defining and measuring the effective coverage of health interventions and their implementation strength to monitor progress towards global mortality and morbidity targets. Existing health system models and frameworks guide thinking around these measurement areas; however, they fall short of adequately capturing the dynamic and multi-level relationships between different components of the health system. These relationships must be articulated for measurement and managed to effectively deliver health interventions of sufficient quality to achieve health impacts. Save the Children's Saving Newborn Lives programme and EnCompass LLC, its evaluation partner, developed and applied the Pathway to High Effective Coverage as a health systems thinking framework (hereafter referred to as the Pathway) in its strategic planning, monitoring and evaluation. METHODS: We used an iterative approach to develop, test and refine thinking around the Pathway. The initial framework was developed based on existing literature, then shared and vetted during consultations with global health thought leaders in maternal and newborn health. RESULTS: The Pathway is a robust health systems thinking framework that unpacks system, policy and point of intervention delivery factors, thus encouraging specific actions to address gaps in implementation and facilitate the achievement of high effective coverage. The Pathway includes six main components - (1) national readiness; (2) system structures; (3) management capacity; (4) implementation strength; (5) effective coverage; and (6) impact. Each component is comprised of specific elements reflecting the range of facility-, community- and home-based interventions. We describe applications of the Pathway and results for in-country strategic planning, monitoring of progress and implementation strength, and evaluation. CONCLUSIONS: The Pathway provides a cohesive health systems thinking framework that facilitates assessment and coordinated action to achieve high coverage and impact. Experiences of its application show its utility in guiding strategic planning and in more comprehensive and effective monitoring and evaluation as well as its potential adaptability for use in other health areas and sectors.

Hyperbaric oxygen therapy for COVID-19 patients with respiratory distress: treated cases versus propensity-matched controls.

Objective: Given the high mortality and prolonged duration of mechanical ventilation of COVID-19 patients, we evaluated the safety and efficacy of hyperbaric oxygen for COVID-19 patients with respiratory distress. Methods: This is a single-center clinical trial of COVID-19 patients at NYU Winthrop Hospital from March 31 to April 28, 2020. Patients in this trial received hyperbaric oxygen therapy at 2.0 atmospheres of pressure in monoplace hyperbaric chambers for 90 minutes daily for a maximum of five total treatments. Controls were identified using propensity score matching among COVID-19 patients admitted during the same time period. Using competing-risks survival regression, we analyzed our primary outcome of inpatient mortality and secondary outcome of mechanical ventilation. Results: We treated 20 COVID-19 patients with hyperbaric oxygen. Ages ranged from 30 to 79 years with an oxygen requirement ranging from 2 to 15 liters on hospital days 0 to 14. Of these 20 patients, two (10%) were intubated and died, and none remain hospitalized. Among 60 propensity-matched controls based on age, sex, body mass index, coronary artery disease, troponin, D-dimer, hospital day, and oxygen requirement, 18 (30%) were intubated, 13 (22%) have died, and three (5%) remain hospitalized (with one still requiring mechanical ventilation). Assuming no further deaths among controls, we estimate that the adjusted subdistribution hazard ratios were 0.37 for inpatient mortality (p=0.14) and 0.26 for mechanical ventilation (p=0.046). Conclusion: Though limited by its study design, our results demonstrate the safety of hyperbaric oxygen among COVID-19 patients and strongly suggests the need for a well-designed, multicenter randomized control trial.

Nondestructive Extraction and Identification of Microplastics from Freshwater Sport Fish Stomachs.

Microplastics were extracted from freshwater sport fish stomachs containing substantial biomass and identified using optical microscopy, scanning electron microscopy plus energy-dispersive X-ray spectroscopy (SEM/EDS), and Fourier transform infrared (FTIR) micro-spectroscopy with automated spectral mapping. An extraction method is presented that uses a negatively pressurized sieve stack and purified water to preserve plastic surface characteristics and any adsorbed persistent organic pollutants (POPs). This nondestructive extraction method for large predators' stomachs enables multiple trophic-level studies from one fish sampling event and provides other dietary and behavioral data. FTIR-identified microplastics 50-1500 µm, including polyethylene (two with plastic additive POPs), styrene acrylonitrile, polystyrene, and nylon and polyethylene terephthalate fibers 10-50 µm wide. SEM/EDS revealed characteristic surface weathering on the plastic surfaces. The nylon fibers appear to be from human fishing activities, suggesting options for management. Some particles visually identified as potential plastics were revealed by micro-spectroscopy to be mineralized, natural polyamide proteins, or nonplastic shell pieces. A low-cost, reflective sample preparation method with stable particle mounting was developed to enable automated mapping, improved FTIR throughput, and lower detection size limit. This study yielded 37 intact prey items set aside for future analyses.

Real-world cell phone radiofrequency electromagnetic field exposures.

In 2011 the International Agency for Research on Cancer classified radiofrequency electromagnetic fields (RF EMF) from cell phones as possibly carcinogenic to humans. The National Toxicology Program and the Ramazzini Institute have both reported that RF EMF exposures significantly increase gliomas and Schwannomas of the heart in rodent studies. Recent studies indicate that RF EMF exposures from cell phones have negative impacts on animal cells and cognitive and/or behavioral development in children. Case-control epidemiological studies have found evidence for cell phone use and increased risk for glioma and localization of the glioma associated with the consistent exposure site of regular cell phone use. Understanding the exposure level, or power density, from RF EMF emitted by cell phones under real-world usage and signal reception conditions, as distinct from the published measurements of maximum Specific Absorption Rate values, may help cell phone users decide whether to take behavioral steps to reduce RF EMF exposure. Exposure measurements were conducted on phone models from four major mobile network operators (MNOs) in the USA for calls received under strong and weak reception signal conditions, near the phone face and at several distances up to 48 cm. RF EMF exposure from all phones was found to be greater under weak (1-2 display bars) than under strong (4-5 display bars) reception signal conditions by up to four orders of magnitude. Notably, RF EMF exposure levels under weak reception signal conditions at a distance of 48 cm from the phone were similar to or greater than those detected under strong reception signal conditions at a distance of 4 cm. Under weak reception signal conditions, power density reductions of up to 90% occurred at 16 cm typical for speaker phone or texting over the 4 cm near-ear exposure. The results of this investigation of second-generation (2G) technology suggest that reduced and precautionary use of cell phones under weak signal conditions could lower a user's RF EMF exposure by up to several orders of magnitude. Bluetooth headset power density exposures were 10-400 times lower than those of the cell phones to which they were connected and dependent on the headset rather than the connected phone. The results of this study informed the development of public health guidance regarding cell phone use.

Age Disparities Among Patients With Type 2 Diabetes and Associated Rates of Hospital Use and Diabetic Complications.

INTRODUCTION: Although screening for diabetes is recommended at age 45, some populations may be at greater risk at earlier ages. Our objective was to quantify age disparities among patients with type 2 diabetes in New York City. METHODS: Using all-payer hospital claims data for New York City, we performed a cross-sectional analysis of patients with type 2 diabetes identified from emergency department visits during the 5-year period 2011-2015. We estimated type 2 diabetes prevalence at each year of life, the age distribution of patients stratified by decade, and the average age of patients by sex, race/ethnicity, and geographic location. RESULTS: We identified 576,306 unique patients with type 2 diabetes. These patients represented more than half of all people with type 2 diabetes in New York City. Patients in racial/ethnic minority groups were on average 5.5 to 8.4 years younger than non-Hispanic white patients. At age 45, type 2 diabetes prevalence was 10.9% among non-Hispanic black patients and 5.2% among non-Hispanic white patients. In our geospatial analyses, patients with type 2 diabetes were on average 6 years younger in hotspots of diabetes-related emergency department use and inpatient hospitalizations. The average age of patients with type 2 diabetes was also 1 to 2 years younger in hotspots of microvascular diabetic complications. CONCLUSION: We identified profound age disparities among patients with type 2 diabetes in racial/ethnic minority groups and in neighborhoods with poor health outcomes. The younger age of these patients may be due to earlier onset of diabetes and/or earlier death from diabetic complications. Our findings demonstrate the need for geographically targeted interventions that promote earlier diagnosis and better glycemic control.

Functional outcomes after inpatient rehabilitation for trauma-improved but unable to return home.

BACKGROUND: Twenty-five percent of trauma patients are discharged to postacute care, indicating a loss of physical function and need for rehabilitation. The purpose of this study was to quantify the functional improvements in trauma patients discharged from inpatient rehabilitation facility (IRF) and identify predictors of improvement. MATERIALS AND METHODS: A retrospective cohort study of trauma patients aged ≥ 18 years were admitted to an IRF after discharge from a level-1 trauma center. Data included demographics, injury characteristics, hospital, and IRF course. The functional independence measure (FIM) was used to measure change in physical and cognitive function. RESULTS: There were 245 patients with a mean age of 55.8 years and mean injury severity score (ISS) of 14.7. Fall was the leading mechanism of injury (45.7%). On IRF admission, 50.7% of patients required moderate or greater assistance. On discharge, the mean intraindividual change in FIM score was 29.9; 85.4% of the patients improved by ≥1 level of functioning. Before injury, 99.6% of patients were living at home, but only 56.0% were discharged home from the IRF, despite 81.8% requiring minimal assistance at most (23.5% to skilled nursing; 19.7% readmitted). Increasing age and lower ISS were associated with less FIM improvement, and increasing ISS was associated with increased FIM improvement. CONCLUSIONS: More than 80% of the trauma patients experienced meaningful functional improvements during IRF admission. However, only half were discharged home, and a quarter required further institutional care. Further research is needed to identify the additional impediments to return to preinjury functioning.
