Enhancing electrospray ionization efficiency for particle transmission through an aerodynamic lens stack

This work investigates the performance of the electrospray aerosol generator at the European X-ray Free Electron Laser (EuXFEL). This generator is, together with an aerodynamic lens stack that transports the particles into the X-ray interaction vacuum chamber, the method of choice to deliver particles for single-particle coherent diffractive imaging (SPI) experiments at the EuXFEL. For these experiments to be successful, it is necessary to achieve high transmission of particles from solution into the vacuum interaction region. Particle transmission is highly dependent on efficient neutralization of the charged aerosol generated by the electrospray mechanism as well as the geometry in the vicinity of the Taylor cone. We report absolute particle transmission values for different neutralizers and geometries while keeping the conditions suitable for SPI experiments. Our findings reveal that a vacuum ultraviolet ionizer demonstrates a transmission efficiency approximately seven times greater than the soft X-ray ionizer used previously. Combined with an optimized orifice size on the counter electrode, we achieve >40% particle transmission from solution into the X-ray interaction region. These findings offer valuable insights for optimizing electrospray aerosol generator configurations and data rates for SPI experiments.

VerSoX B07-B: a high-throughput XPS and ambient pressure NEXAFS beamline at Diamond Light Source

The beamline optics and endstations at branch B of the Versatile Soft X-ray (VerSoX) beamline B07 at Diamond Light Source are described. B07-B provides medium-flux X-rays in the range 45–2200 eV from a bending magnet source, giving access to local electronic structure for atoms of all elements from Li to Y. It has an endstation for high-throughput X-ray photoelectron spectroscopy (XPS) and near-edge X-ray absorption fine-structure (NEXAFS) measurements under ultrahigh-vacuum (UHV) conditions. B07-B has a second endstation dedicated to NEXAFS at pressures from UHV to ambient pressure (1 atm). The combination of these endstations permits studies of a wide range of interfaces and materials. The beamline and endstation designs are discussed in detail, as well as their performance and the commissioning process.

Evaluation of the X-ray/EUV Nanolithography Facility at AS through wavefront propagation simulations

Synchrotron light sources can provide the required spatial coherence, stability and control to support the development of advanced lithography at the extreme ultraviolet and soft X-ray wavelengths that are relevant to current and future fabricating technologies. Here an evaluation of the optical performance of the soft X-ray (SXR) beamline of the Australian Synchrotron (AS) and its suitability for developing interference lithography using radiation in the 91.8 eV (13.5 nm) to 300 eV (4.13 nm) range are presented. A comprehensive physical optics model of the APPLE-II undulator source and SXR beamline was constructed to simulate the properties of the illumination at the proposed location of a photomask, as a function of photon energy, collimation and monochromator parameters. The model is validated using a combination of experimental measurements of the photon intensity distribution of the undulator harmonics. It is shown that the undulator harmonics intensity ratio can be accurately measured using an imaging detector and controlled using beamline optics. Finally, the photomask geometric constraints and achievable performance for the limiting case of fully spatially coherent illumination are evaluated.

Mapping of lithium ion concentrations in 3D structures through development of in situ correlative imaging of X-ray Compton scattering-computed tomography

Understanding the correlation between chemical and microstructural properties is critical for unraveling the fundamental relationship between materials chemistry and physical structures that can benefit materials science and engineering. Here, we demonstrate novel in situ correlative imaging of the X-ray Compton scattering computed tomography (XCS-CT) technique for studying this fundamental relationship. XCS-CT can image light elements that do not usually exhibit strong signals using other X-ray characterization techniques. This paper describes the XCS-CT setup and data analysis method for calculating the valence electron momentum density and lithium-ion concentration, and provides two examples of spatially and temporally resolved chemical properties inside batteries in 3D. XCS-CT was applied to study two types of rechargeable lithium batteries in standard coin cell casings: (1) a lithium-ion battery containing a cathode of bespoke microstructure and liquid electrolyte, and (2) a solid-state battery containing a solid-polymer electrolyte. The XCS-CT technique is beneficial to a wide variety of materials and systems to map chemical composition changes in 3D structures.

High-throughput and high-resolution powder X-ray diffractometer consisting of six sets of 2D CdTe detectors with variable sample-to-detector distance and innovative automation system

The demand for powder X-ray diffraction analysis continues to increase in a variety of scientific fields, as the excellent beam quality of high-brightness synchrotron light sources enables the acquisition of high-quality measurement data with high intensity and angular resolution. Synchrotron powder diffraction has enabled the rapid measurement of many samples and various in situ/operando experiments in nonambient sample environments. To meet the demands for even higher throughput measurements using high-energy X-rays at SPring-8, a high-throughput and high-resolution powder diffraction system has been developed. This system is combined with six sets of two-dimensional (2D) CdTe detectors for high-energy X-rays, and various automation systems, including a system for automatic switching among large sample environmental equipment, have been developed in the third experimental hutch of the insertion device beamline BL13XU at SPring-8. In this diffractometer system, high-brilliance and high-energy X-rays ranging from 16 to 72 keV are available. The powder diffraction data measured under ambient and various nonambient conditions can be analysed using Rietveld refinement and the pair distribution function. Using the 2D CdTe detectors with variable sample-to-detector distance, three types of scan modes have been established: standard, single-step and high-resolution. A major feature is the ability to measure a whole powder pattern with millisecond resolution. Equally important, this system can measure powder diffraction data with high Q exceeding 30 Å−1 within several tens of seconds. This capability is expected to contribute significantly to new research avenues using machine learning and artificial intelligence by utilizing the large amount of data obtained from high-throughput measurements.

High-angular-sensitivity X-ray phase-contrast microtomography of soft tissue through a two-directional beam-tracking synchrotron set-up

Two-directional beam-tracking (2DBT) is a method for phase-contrast imaging and tomography that uses an intensity modulator to structure the X-ray beam into an array of independent circular beamlets that are resolved by a high-resolution detector. It features isotropic spatial resolution, provides two-dimensional phase sensitivity, and enables the three-dimensional reconstructions of the refractive index decrement, δ, and the attenuation coefficient, μ. In this work, the angular sensitivity and the spatial resolution of 2DBT images in a synchrotron-based implementation is reported. In its best configuration, angular sensitivities of ∼20 nrad and spatial resolution of at least 6.25 µm in phase-contrast images were obtained. Exemplar application to the three-dimensional imaging of soft tissue samples, including a mouse liver and a decellularized porcine dermis, is also demonstrated.

Accelerating imaging research at large-scale scientific facilities through scientific computing

To date, computed tomography experiments, carried-out at synchrotron radiation facilities worldwide, pose a tremendous challenge in terms of the breadth and complexity of the experimental datasets produced. Furthermore, near real-time three-dimensional reconstruction capabilities are becoming a crucial requirement in order to perform high-quality and result-informed synchrotron imaging experiments, where a large amount of data is collected and processed within a short time window. To address these challenges, we have developed and deployed a synchrotron computed tomography framework designed to automatically process online the experimental data from the synchrotron imaging beamlines, while leveraging the high-performance computing cluster capabilities to accelerate the real-time feedback to the users on their experimental results. We have, further, integrated it within a modern unified national authentication and data management framework, which we have developed and deployed, spanning the entire data lifecycle of a large-scale scientific facility. In this study, the overall architecture, functional modules and workflow design of our synchrotron computed tomography framework are presented in detail. Moreover, the successful integration of the imaging beamlines at the Shanghai Synchrotron Radiation Facility into our scientific computing framework is also detailed, which, ultimately, resulted in accelerating and fully automating their entire data processing pipelines. In fact, when compared with the original three-dimensional tomography reconstruction approaches, the implementation of our synchrotron computed tomography framework led to an acceleration in the experimental data processing capabilities, while maintaining a high level of integration with all the beamline processing software and systems.

HEIDI: an experiment-management platform enabling high-throughput fragment and compound screening

The Swiss Light Source facilitates fragment-based drug-discovery campaigns for academic and industrial users through the Fast Fragment and Compound Screening (FFCS) software suite. This framework is further enriched by the option to utilize the Smart Digital User (SDU) software for automated data collection across the PXI, PXII and PXIII beamlines. In this work, the newly developed HEIDI webpage (https://heidi.psi.ch) is introduced: a platform crafted using state-of-the-art software architecture and web technologies for sample management of rotational data experiments. The HEIDI webpage features a data-review tab for enhanced result visualization and provides programmatic access through a representational state transfer application programming interface (REST API). The migration of the local FFCS MongoDB instance to the cloud is highlighted and detailed. This transition ensures secure, encrypted and consistently accessible data through a robust and reliable REST API tailored for the FFCS software suite. Collectively, these advancements not only significantly elevate the user experience, but also pave the way for future expansions and improvements in the capabilities of the system.

RCSB Protein Data Bank: supporting research and education worldwide through explorations of experimentally determined and computationally predicted atomic level 3D biostructures

The Protein Data Bank (PDB) was established as the first open-access digital data resource in biology and medicine in 1971 with seven X-ray crystal structures of proteins. Today, the PDB houses >210 000 experimentally determined, atomic level, 3D structures of proteins and nucleic acids as well as their complexes with one another and small molecules (e.g. approved drugs, enzyme cofactors). These data provide insights into fundamental biology, biomedicine, bioenergy and biotechnology. They proved particularly important for understanding the SARS-CoV-2 global pandemic. The US-funded Research Collaboratory for Structural Bioinformatics Protein Data Bank (RCSB PDB) and other members of the Worldwide Protein Data Bank (wwPDB) partnership jointly manage the PDB archive and support >60 000 `data depositors' (structural biologists) around the world. wwPDB ensures the quality and integrity of the data in the ever-expanding PDB archive and supports global open access without limitations on data usage. The RCSB PDB research-focused web portal at https://www.rcsb.org/ (RCSB.org) supports millions of users worldwide, representing a broad range of expertise and interests. In addition to retrieving 3D structure data, PDB `data consumers' access comparative data and external annotations, such as information about disease-causing point mutations and genetic variations. RCSB.org also provides access to >1 000 000 computed structure models (CSMs) generated using artificial intelligence/machine-learning methods. To avoid doubt, the provenance and reliability of experimentally determined PDB structures and CSMs are identified. Related training materials are available to support users in their RCSB.org explorations.

Comprehensive encoding of conformational and compositional protein structural ensembles through the mmCIF data structure

In the folded state, biomolecules exchange between multiple conformational states crucial for their function. However, most structural models derived from experiments and computational predictions only encode a single state. To represent biomolecules accurately, we must move towards modeling and predicting structural ensembles. Information about structural ensembles exists within experimental data from X-ray crystallography and cryo-electron microscopy. Although new tools are available to detect conformational and compositional heterogeneity within these ensembles, the legacy PDB data structure does not robustly encapsulate this complexity. We propose modifications to the macromolecular crystallographic information file (mmCIF) to improve the representation and interrelation of conformational and compositional heterogeneity. These modifications will enable the capture of macromolecular ensembles in a human and machine-interpretable way, potentially catalyzing breakthroughs for ensemble–function predictions, analogous to the achievements of AlphaFold with single-structure prediction.

Structural characterization of TIR-domain signalosomes through a combination of structural biology approaches

The TIR (Toll/interleukin-1 receptor) domain represents a vital structural element shared by proteins with roles in immunity signalling pathways across phyla (from humans and plants to bacteria). Decades of research have finally led to identifying the key features of the molecular basis of signalling by these domains, including the formation of open-ended (filamentous) assemblies (responsible for the signalling by cooperative assembly formation mechanism, SCAF) and enzymatic activities involving the cleavage of nucleotides. We present a historical perspective of the research that led to this understanding, highlighting the roles that different structural methods played in this process: X-ray crystallography (including serial crystallography), microED (micro-crystal electron diffraction), NMR (nuclear magnetic resonance) spectroscopy and cryo-EM (cryogenic electron microscopy) involving helical reconstruction and single-particle analysis. This perspective emphasizes the complementarity of different structural approaches.

High-throughput nanoscale crystallization of di­hydro­pyridine active pharmaceutical ingredients

Single-crystal X-ray diffraction analysis of small molecule active pharmaceutical ingredients is a key technique in the confirmation of molecular connectivity, including absolute stereochemistry, as well as the solid-state form. However, accessing single crystals suitable for X-ray diffraction analysis of an active pharmaceutical ingredient can be experimentally laborious, especially considering the potential for multiple solid-state forms (solvates, hydrates and polymorphs). In recent years, methods for the exploration of experimental crystallization space of small molecules have undergone a `step-change', resulting in new high-throughput techniques becoming available. Here, the application of high-throughput encapsulated nanodroplet crystallization to a series of six di­hydro­pyridines, calcium channel blockers used in the treatment of hypertension related diseases, is described. This approach allowed 288 individual crystallization experiments to be performed in parallel on each molecule, resulting in rapid access to crystals and subsequent crystal structures for all six di­hydro­pyridines, as well as revealing a new solvate polymorph of nifedipine (1,4-dioxane solvate) and the first known solvate of nimodipine (DMSO solvate). This work further demonstrates the power of modern high-throughput crystallization methods in the exploration of the solid-state landscape of active pharmaceutical ingredients to facilitate crystal form discovery and structural analysis by single-crystal X-ray diffraction.

Unlocking the surface chemistry of ionic minerals: a high-throughput pipeline for modeling realistic interfaces

A systematic procedure is introduced for modeling charge-neutral non-polar surfaces of ionic minerals containing polyatomic anions. By integrating distance- and charge-based clustering to identify chemical species within the mineral bulk, our pipeline, PolyCleaver, renders a variety of theoretically viable surface terminations. As a demonstrative example, this approach was applied to forsterite (Mg2SiO4), unveiling a rich interface landscape based on interactions with formaldehyde, a relevant multifaceted molecule, and more particularly in prebiotic chemistry. This high-throughput method, going beyond techniques traditionally applied in the modeling of minerals, offers new insights into the potential catalytic properties of diverse surfaces, enabling a broader exploration of synthetic pathways in complex mineral systems.

Mitigation of DMM-induced stripe patterns in synchrotron X-ray radiography through dynamic tilting

In synchrotron X-ray radiography, achieving high image resolution and an optimal signal-to-noise ratio (SNR) is crucial for the subsequent accurate image analysis. Traditional methods often struggle to balance these two parameters, especially in situ applications where rapid data acquisition is essential to capture specific dynamic processes. For quantitative image data analysis, using monochromatic X-rays is essential. A double multilayer monochromator (DMM) is successfully used for this aim at the BAMline, BESSY II (Helmholtz Zentrum Berlin, Germany). However, such DMMs are prone to producing an unstable horizontal stripe pattern. Such an unstable pattern renders proper signal normalization difficult and thereby causes a reduction of the SNR. We introduce a novel approach to enhance SNR while preserving resolution: dynamic tilting of the DMM. By adjusting the orientation of the DMM during the acquisition of radiographic projections, we optimize the X-ray imaging quality, thereby enhancing the SNR. The corresponding shift of the projection during this movement is corrected in post-processing. The latter correction allows a good resolution to be preserved. This dynamic tilting technique enables the homogenization of the beam profile and thereby effectively reduces noise while maintaining high resolution. We demonstrate that data captured using this proposed technique can be seamlessly integrated into the existing radiographic data workflow, as it does not need hardware modifications to classical X-ray imaging beamline setups. This facilitates further image analysis and processing using established methods.

CDC Extends Eviction Moratorium Through July

Pam Fessler | NPR

The Centers for Disease Control and Prevention has extended a moratorium on evictions until the end of July. The ban had been set to expire next week, raising concerns that there could be a flood of evictions with some seven million tenants currently behind on their rent.

The Biden administration says the extension is for "one final month" and will allow time for it to take other steps to stabilize housing for those facing eviction and foreclosure. The White House says it is encouraging state and local courts to adopt anti-eviction diversion programs to help delinquent tenants stay housed and avoid legal action.

The federal government will also try to speed up distribution of tens of billions of dollars in emergency rental assistance that's available but has yet to be spent. In addition, a moratorium on foreclosures involving federally backed mortgages has been extended for "a final month," until July 31.

In announcing the extension of the eviction moratorium, the CDC said that the COVID-19 "pandemic has presented a historic threat to the nation's public health. Keeping people in their homes and out of crowded or congregate settings — like homeless shelters — by preventing evictions is a key step in helping to stop the spread of COVID-19."

The CDC first issued the moratorium last September. It was extended once already in March, until June 30.

But landlords have been pushing back, arguing that they've taken a huge financial hit over the past year, losing billions of dollars a month in rent. Several business groups have sued the CDC and won, though court decisions to lift the moratorium have been stayed pending appeal.

The Alabama Association of Realtors, which brought one of the cases, argued that the CDC exceeded its authority in issuing the ban. The group is seeking relief from the U.S. Supreme Court, but the justices have yet to respond.

In its petition, the Realtors association called the CDC's "continued insistence that public-health concerns necessitate that landlords continue to provide free housing for tenants who have received vaccines (or passed up the chance to get them)...sheer doublespeak."

Housing advocates have argued that the moratorium is still very much needed. They note that $46 billion in emergency rental assistance approved by Congress has been slow getting into the hands of those it was intended to help. The money is supposed to cover rent that tenants currently owe.

The National Low Income Housing Coalition reports that in some states, less than five percent of the funds have been distributed so far. The group pushed the administration to extend the ban to give states and localities more time to get the money out.

Despite the moratorium, thousands of renters have still faced the threat of eviction because of loopholes in the law. Many are the lowest income tenants and disproportionately people of color. A new study by the Eviction Lab at Princeton University has found that communities with the lowest vaccination rates tend to have the highest eviction filings, raising additional health concerns.

"Allowing the moratorium to expire before vaccination rates increase in marginalized communities could lead to increased spread of, and deaths from, COVID-19," a group of more than 40 House lawmakers wrote in a letter this week to President Biden and CDC Director Rochelle Walensky, urging them to extend the moratorium.

He Inherited A Devastating Disease. A CRISPR Gene-Editing Breakthrough Stopped It

Patrick Doherty volunteered for a new medical intervention of gene-editor infusions for the treatment of genetically-based diseases.; Credit: /Patrick Doherty

Rob Stein | NPR

Patrick Doherty had always been very active. He trekked the Himalayas and hiked trails in Spain.

But about a year and a half ago, he noticed pins and needles in his fingers and toes. His feet got cold. And then he started getting out of breath any time he walked his dog up the hills of County Donegal in Ireland where he lives.

"I noticed on some of the larger hill climbs I was getting a bit breathless," says Doherty, 65. "So I realized something was wrong."

Doherty found out he had a rare, but devastating inherited disease — known as transthyretin amyloidosis — that had killed his father. A misshapen protein was building up in his body, destroying important tissues, such as nerves in his hands and feet and his heart.

Doherty had watched others get crippled and die difficult deaths from amyloidosis.

"It's terrible prognosis," Doherty says. "This is a condition that deteriorates very rapidly. It's just dreadful."

So Doherty was thrilled when he found out that doctors were testing a new way to try to treat amyloidosis. The approach used a revolutionary gene-editing technique called CRISPR, which allows scientists to make very precise changes in DNA.

"I thought: Fantastic. I jumped at the opportunity," Doherty says.

On Saturday, researchers reported the first data indicating that the experimental treatment worked, causing levels of the destructive protein to plummet in Doherty's body and the bodies of five other patients treated with the approach.

"I feel fantastic," Doherty says. "It's just phenomenal."

The advance is being hailed not just for amyloidosis patients but also as a proof-of-concept that CRISPR could be used to treat many other, much more common diseases. It's a new way of using the innovative technology.

"This is a major milestone for patients," says Jennifer Doudna of the University of California, Berkeley, who shared a Nobel Prize for her work helping develop CRISPR.

"While these are early data, they show us that we can overcome one of the biggest challenges with applying CRISPR clinically so far, which is being able to deliver it systemically and get it to the right place," Doudna says.

CRISPR has already been shown to help patients suffering from the devastating blood disorders sickle cell disease and beta thalassemia. And doctors are trying to use it to treat cancer and to restore vision to people blinded by a rare genetic disorder.

But those experiments involve taking cells out of the body, editing them in the lab, and infusing them back in or injecting CRISPR directly into cells that need fixing.

The study Doherty volunteered for is the first in which doctors are simply infusing the gene-editor directly into patients and letting it find its own way to the right gene in the right cells. In this case, it's cells in the liver making the destructive protein.

"This is the first example in which CRISPR-Cas9 is injected directly into the bloodstream — in other words systemic administration — where we use it as a way to reach a tissue that's far away from the site of injection and very specifically use it to edit disease-causing genes," says John Leonard, the CEO of Intellia Therapeutics, which is sponsoring the study.

Doctors infused billions of microscopic structures known as nanoparticles carrying genetic instructions for the CRISPR gene-editor into four patients in London and two in New Zealand. The nanoparticles were absorbed by their livers, where they unleashed armies of CRISPR gene-editors. The CRISPR editor honed in on the target gene in the liver and sliced it, disabling production of the destructive protein.

Within weeks, the levels of protein causing the disease plummeted. Researchers reported at the Peripheral Nerve Society Annual Meeting and in a paper published in The New England Journal of Medicine.

"It really is exciting," says Dr. Julian Gillmore, who is leading the study at the University College London, Royal Free Hospital.

"This has the potential to completely revolutionize the outcome for these patients who have lived with this disease in their family for many generations. It's decimated some families that I've been looking after. So this is amazing," Gillmore says.

The patients will have to be followed longer, and more patients will have to be treated, to make sure the treatment's safe, and determine how much it's helping, Gillmore stresses. But the approach could help those struck by amyloidosis that isn't inherited, which is a far more common version of the disease, he says.

Moreover, the promising results potentially open the door for using the same approach to treatment of many other, more common diseases for which taking cells out of the body or directly injecting CRISPR isn't realistic, including heart disease, muscular dystrophy and brain diseases such as Alzheimer's.

"This is really opening a new era as we think about gene-editing where we can begin to think about accessing all kinds of different tissue in the body via systemic administration," Leonard says.

Other scientists who are not involved in the research agree.

"This is a wonderful day for the future of gene-editing as a medicine,"
agree Fyodor Urnov, a professor of genetics at the University of California, Berkeley. "We as a species are watching this remarkable new show called: our gene-edited future."

Doherty says he started feeling better within weeks of the treatment and has continued to improve in the weeks since then.

"I definitely feel better," he told NPR. "I'm speaking to you from upstairs in our house. I climbed stairs to get up here. I would have been feeling breathless. I'm thrilled."

A Hospital Charged More Than $700 For Each Push Of Medicine Through Her IV

; Credit: /Rose Wong for NPR/KHN

Rae Ellen Bichell | NPR

Claire Lang-Ree was in a lab coat taking a college chemistry class remotely in the kitchen of her Colorado Springs, Colo., home, when a profound pain twisted into her lower abdomen. She called her mom, Jen Lang-Ree, a nurse practitioner who worried it was appendicitis and found a nearby hospital in the family's health insurance network.

After a long wait in the emergency room of Penrose Hospital, Claire received morphine and an anti-nausea medication delivered through an IV. She also underwent a CT scan of her abdomen and a series of tests.

Hospital staffers ruled out appendicitis and surmised Claire was suffering from a ruptured ovarian cyst, which can be a harmless part of the menstrual cycle but can also be problematic and painful. After a few days — and a chemistry exam taken through gritted teeth — the pain went away.

Then the bill came.

Patient: Claire Lang-Ree, a 21-year-old Stanford University student who was living in Colorado for a few months while taking classes remotely. She's insured by Anthem Blue Cross through her mom's work as a pediatric nurse practitioner in Northern California.

Total Bill: $18,735.93, including two $722.50 fees for a nurse to "push" drugs into her IV, a process that takes seconds. Anthem's negotiated charges were $6,999 for the total treatment. Anthem paid $5,578.30, and the Lang-Rees owed $1,270.45 to the hospital, plus additional bills for radiologists and other care. (Claire also anted up a $150 copay at the ER.)

Service Provider: Penrose Hospital in Colorado Springs, part of the regional health care network Centura Health.

What Gives: As hospitals disaggregate charges for services once included in an ER visit, a hospitalization or a surgical procedure, there has been a proliferation of newfangled fees to increase billing. In the health field, this is called "unbundling." It's analogous to the airlines now charging extra for each checked bag or for an exit row seat. Over time, in the medical industry, this has led to separate fees for ever-smaller components of care. A charge to put medicine into a patient's IV line — a "push fee" — is one of them.

Though the biggest charge on Claire's bill, $9,885.73, was for a CT scan, in many ways Claire and her mom found the push fees most galling. (Note to readers: Scans are frequently many times more expensive when ordered in an ER than in other settings.)

"That was so ridiculous," says Claire, who adds she had previously taken the anti-nausea drug they gave her; it's available in tablet form for the price of a cup of coffee, no IV necessary. "It works really well. Why wasn't that an option?"

In Colorado, the average charge for the code corresponding to Claire's first IV push has nearly tripled since 2014, and the dollars hospitals actually get for the procedure has doubled. In Colorado Springs specifically, the cost for IV pushes rose even more sharply than it did statewide.

A typical nurse in Colorado Springs makes about $35 an hour. At that rate, it would take nearly 21 hours to earn the amount of money Penrose charged for a push of plunger that likely took seconds or at most minutes.

The hospital's charge for just one "IV push" was more than Claire's portion of the monthly rent in the home she shared with roommates. In the end, Anthem did not pay the push fees in its negotiated payment. But claims data shows that in 2020 Penrose typically received upward of $1,000 for the first IV push. And patients who didn't have an insurer to dismiss such charges would be stuck with them. Colorado hospitals on average received $723 for the same code, according to the claims database.

"It's insane the variation that we see in prices, and there's no rhyme or reason," says Cari Frank with the Center for Improving Value in Health Care, a Colorado nonprofit that runs a statewide health care claims database. "It's just that they've been able to negotiate those prices with the insurance company and the insurance company has decided to pay it."

To put the total cost in context, Penrose initially charged more money for Claire's visit than the typical Colorado hospital would have charged for helping someone give birth, according to data published by the Colorado Division of Insurance.

Even with the negotiated rate, "it was only $1,000 less than an average payment for having a baby," Frank says.

In an email statement, Centura said it "conducted a thorough review and determined all charges were accurate" and went on to explain that "an Emergency Room (ER) must be prepared for anything and everything that comes through the doors," requiring highly trained staff, plus equipment and supplies. "All of this adds up to large operating costs and can translate into patient responsibility."

As researchers have found, little stands in the way of hospitals charging through the roof, especially in a place like an emergency room, where a patient has few choices. A report from National Nurses United found that hospital markups have more than doubled since 1999, according to data from the United States Bureau of Labor Statistics. In an email, Anthem called the trend of increasing hospital prices "alarming" and "unsustainable."

But Ge Bai, an associate professor of accounting and health policy at Johns Hopkins University, says when patients see big bills it isn't only the hospital's doing — a lot depends on the insurer, too. For one, the negotiated price depends on the negotiating power of the payer, in this case, Anthem.

"Most insurance companies don't have comparable negotiating or bargaining power with the hospital," said Bai. Prices in a state like Michigan, where Bai said the UAW union covers a big proportion of Michigan patients, will look very different from those in Colorado.

Also, insurers are not the wallet defenders patients might assume them to be.

"In many cases, insurance companies don't negotiate as aggressively as they can, because they earn profit from the percentage of the claims," she says. The more expensive the actual payment is, the more money they get to extract.

Though Anthem negotiated away the push fees, it paid the hospital 30% more than the average Level IV emergency department visit in Colorado that year, and it paid quadruple what Medicare would allow for her CT scan.

Resolution: Claire and her mom decided to fight the bill, writing letters to the hospital and searching for information on what the procedures should have cost. The cost of the IV pushes and CT scan infuriated them — the hospital wanted more than double for a CT than what top-rated hospitals typically charged in 2019.

But the threat of collections wore them out and ultimately they paid their assigned share of the bill — $1,420.45, which was mostly coinsurance.

"Eventually it got to the point where I was like, 'I don't really want to go to collections, because this might ruin my credit score,'" says Claire, who didn't want to graduate from college with dinged credit.

Bai and Frank say the state of Maryland can provide a useful benchmark for medical bills, since it sets the prices that hospitals can charge for each procedure. Data provided by the Maryland Health Care Commission shows that Anthem and Claire paid seven times what she likely would have paid for the CT scan there, and nearly 10 times what they likely would have paid for the emergency department Level IV visit. In Maryland, intravenous pushes typically cost about $200 apiece in 2019. A typical Maryland hospital would have received only about $1,350 from a visit like Claire's, and the Lang-Rees would have been on the hook for about $270.

Claire's pain has come back a few times, but never as bad as that night in Colorado. She has avoided reentering an emergency room since then. After visiting multiple specialists back home in California, she learned she might have had a condition called ovarian torsion.

The Takeaway: Even at an in-network facility and with good insurance, patients can get hurt financially by visiting the ER. A few helpful documents can help guide the way to fighting such charges. The first is an itemized bill.

"I just think it's wrong in the U.S. to charge so much," says Jen Lang-Ree. "It's just a little side passion of mine to look at those and make sure I'm not being scammed."

Bai, of Johns Hopkins, suggests asking for an itemized explanation of benefits from the insurance company, too. That will show what the hospital actually received for each procedure.

Find out if the hospital massively overcharged. The Medicare price lookup tool can be useful for getting a benchmark. And publicly available data on health claims in Colorado and at least 17 other states can help, too.

Vincent Plymell with the Colorado Division of Insurance encourages patients to reach out if something on a bill looks sketchy. "Even if it's not a plan we regulate," he wrote in an email, departments such as his "can always arm the consumer with info."

Finally, make scrutinizing such charges fun. Claire and Jen made bill-fighting their mother-daughter hobby for the winter. They recommend pretzel chips and cocktails to boost the mood.
