A mother's loss launches a global effort to fight antibiotic resistance
In November 2017, days after her daughter Mallory Smith died from a drug-resistant infection at the age of 25, Diane Shader Smith typed a password into Mallory’s laptop.
At this point, keeping myself alive is a full-fledged mission, enlisting all of my energy and hours every day. I need to fight the chronic deadly resistant bacteria eating away at my fragile, scarred lungs. Fight the billions of bacteria overtaking my lungs and clear out the mucus so I don’t feel like I’m breathing through a straw with a boulder weighing on my chest.
— Mallory Smith, Oct. 16, 2014
Her daughter gave it to her before undergoing double-lung transplant surgery, with instructions to share any writing that could help others if she didn’t survive.
Had this idea today that I wanted to write down before it leaves my mind or I stop feeling inspired or I forget it or something inside me tells me it’s not possible. I want to start an online media source (podcast? website?) that tells the stories of people who have struggled with something in their life and found hope somewhere.
— Mallory Smith, July 20, 2015
The transplant was successful, but Burkholderia cepacia — an antibiotic-resistant bacterial strain that first colonized her system when she was 12 — took hold. After a lifetime with cystic fibrosis, and 13 years battling an unconquerable infection, Mallory’s body could take no more.
Cepacia has taken over, and it’s time to figure out a transplant option. I realize I want to write my story.
— Mallory Smith, July 29, 2016
In the haze of grief and pain, Shader Smith found herself looking through 2,500 pages of a journal her daughter had kept since high school. It chronicled Mallory’s hopes and triumphs as an ebullient, athletic student at Beverly Hills High School and Stanford University, and her private despair as bacteria ravaged her systems and sapped her considerable strength.
In the years since, the journal has become a source of solace for Shader Smith as she has traveled the globe speaking about the growing threat of antimicrobial resistance. It is also now the inspiration for two new projects she hopes will spark greater understanding of the public health crisis that ended her daughter’s life prematurely and could claim millions more.

On Tuesday, Random House published “Diary of a Dying Girl,” a selection of Mallory’s journal entries. The same day saw the launch of the Global AMR Diary, a website collecting the worldwide stories of people battling pathogens that can’t be defeated by our current pharmaceutical arsenal.
An estimated 35,000 people die in the U.S. each year from drug-resistant infections, according to the U.S. Centers for Disease Control and Prevention. Worldwide, antimicrobial resistance kills an estimated 1.27 million people directly every year and contributes to the deaths of millions more.
Despite the mounting toll — and the prospect of an eventual surge in superbug fatalities — the development of new antibiotics has stagnated.
Shader Smith is acutely aware of what we stand to lose when medicine can no longer save us.
“I don’t want to live in a post-antibiotic world,” Shader Smith said. “Until people understand what’s at stake, they’re not going to care. My daughter died from this. So I care deeply.”
Over the last 50 years, opportunistic pathogens have evolved defenses faster than humans can develop drugs to combat them.
Misuse of antibiotics has played a large part in this imbalance. Bugs that survive antibiotic exposure pass on their resistant traits, leading to hardier strains.
Crucial as they are, antibiotics don’t have the same financial incentives for developers that other drugs do. They aren’t meant to be taken over the long term, as are medications for chronic conditions such as diabetes or high blood pressure. The most powerful ones have to be used as rarely as possible, to give bacteria fewer opportunities to develop resistances.
“The public does not understand [the] scope of the problem. Antimicrobial resistance truly is one of the leading public health threats of our time,” said Emily Wheeler, director of infectious disease policy at the Biotechnology Innovation Organization. “The pipeline for antibiotics today is already inadequate to address the threats that we know about, without even considering the continuous evolution of these bugs as the years go on.”
Despite the global nature of the threat, Shader Smith said, the response from public health officials is curiously disjointed.
For one, no one can agree on a single name for the problem, she said. Different agencies address the issue with an “alphabet soup” of acronyms: the World Health Organization uses AMR as shorthand for antimicrobial resistance, while the CDC prefers AR. Medical journals, doctors and the media refer alternately to multidrug resistance (MDR), drug-resistant infections (DRI) and superbugs.
“It doesn’t matter what you call it. We just have to all call it the same thing,” said Shader Smith, who works as a publicist and marketing consultant.
Since Mallory’s death, Shader Smith has made it her mission to get the people and organizations working on antimicrobial resistance to talk to one another. For the Global AMR Diary, she enlisted the help of a dozen agencies working on the issue, including the CDC, WHO, the European Center for Disease Prevention and Control (the European Union’s equivalent of the CDC), the Biotechnology Innovation Organization and others.
Antimicrobial resistance can “feel abstract given the scale of the problem,” said John Alter, head of external affairs of the AMR Action Fund, one of the organizations involved with the project. “To know there are millions of families at this very moment going through struggles similar to what Mallory experienced is simply unacceptable,” he said.
“Not only does this firsthand experience help others who might be going through something similar, but it also reminds those tasked with creating solutions and care who they are working for. They aren’t just test tubes or charts,” said Thomas Heymann, chief executive of Sepsis Alliance, another contributor.
The stories in the online diary are often harrowing. A 25-year-old pharmacist in Athens had to put her cancer treatment on hold when an extremely resistant strain of Klebsiella attacked. A veterinarian in Kenya suffered permanent disability after contracting resistant bacteria after hip surgery. Around the world, routine outpatient procedures and illnesses have rapidly become life-threatening when opportunistic bugs take hold.
Mallory was 12 when her doctor called to confirm that her cultures were positive for an extremely resistant strain of cepacia, a form of bacteria found widely in soil and water. The pathogen can be deadly to people with underlying conditions such as cystic fibrosis, a genetic disorder that impairs the cells’ ability to effectively flush mucus from the lungs and other body systems.
Life expectancies for people with cystic fibrosis have grown since Mallory’s diagnosis in 1995, with many people of them living into their 40s and beyond. The cepacia curtailed that possibility for her.
“This is all we’re ever going to have,” Mallory wrote in June 2011, at the end of her freshman year at Stanford, “so if you’re not actively pursuing happiness then you’re insane. And I don’t think I would have this perspective if I didn’t have resistant bacteria that will likely kill me.”

Mallory’s intuition that her journal could be valuable to others was prescient. “People can easily understand and relate to actual experiences,” said Michael Craig, director of the CDC’s Antimicrobial Resistance Coordination and Strategy Unit. “The Global AMR Diary takes this approach and expands on it with a global lens — increasing the potential to get these critical messages to more people around the world.”
An earlier version of Mallory’s diaries was published in 2019 as “Salt in My Soul: An Unfinished Life.” The new book includes entries that Shader Smith said she wasn’t ready to grapple with in the immediate aftermath of Mallory’s passing: ones addressing depression and private despair, concerns about relationships and body image issues complicated by chronic illness.
It also includes a coda about phage therapy, a promising advance against AMR.
As cepacia overwhelmed Mallory’s system in the weeks after her transplant, her family secured an experimental dose of phage therapy. Widely used to treat infection before the advent of antibiotics, phages are viruses that destroy specific bacteria. The treatment arrived too late to save Mallory’s life, Shader Smith writes in a last chapter of the book, but her autopsy revealed that the phages had started to work as intended.
The systems that bring new drugs to patients move slowly, Shader Smith said, and “Mallory might have been saved if they had moved faster.” Her mission now is to make sure that they do.
“Mallory died six years ago. Six years is a long time, day in and day out,” she said. “And I’ve never taken my foot off the pedal.”

There were 13 full-service public health clinics in L.A. County. Now there are 6
Because of budget cuts, the Los Angeles County Department of Public Health has ended clinical services at seven of its public health clinic sites.
As of Feb. 27, the county is no longer providing services such as vaccinations, sexually transmitted infection testing and treatment, or tuberculosis diagnosis and specialty TB care at the affected locations, according to county officials and a department fact sheet.
The sites losing clinical services are Antelope Valley in Lancaster; the Center for Community Health (Leavy) in San Pedro, Curtis R. Tucker in Inglewood, Hollywood-Wilshire, Pomona, Dr. Ruth Temple in South Los Angeles, and Torrance. Services will continue to be provided by the six remaining public health clinics, and through nearby community clinics.
The changes are the result of about $50 million in funding losses, according to official county statements.
“That pushed us to make the very difficult decision to end clinical services at seven of our sites,” said Dr. Anish Mahajan, chief deputy director of the L.A. County Department of Public Health.
Mahajan said the department selected clinics with relatively lower patient volumes. Over the last month, he said, the department has sent letters to patients about the changes, and referred them to unaffected county clinics, nearby federally qualified health centers or other community providers. According to Mahajan, for tuberculosis patients, particularly those requiring directly observed therapy, public health nurses will continue visiting patients.
Public health clinics form part of the county’s healthcare safety net, serving low-income residents and those with limited access to care. Officials said that about half of the patients the county currently sees across its clinics are uninsured.
Mahajan noted that the clinics were established decades ago, before the Affordable Care Act expanded Medi-Cal coverage and increased the number of federally qualified health centers. He said that as more residents gained access to primary care, utilization at some county-run clinics declined.
“Now that we have a more sophisticated safety net, people often have another place to go for their full range of care,” he said.
Still, the closures have unsettled providers who work closely with local vulnerable populations.
“I hate to see any services that serve our at-risk and homeless community shut down,” said Mark Hood, chief executive of Union Rescue Mission in downtown Los Angeles. “There’s so much need out there, so it always is going to create hardship for the people that actually need the help the most.”
Union Rescue Mission does not receive government funding for its healthcare services, Hood said. The mission’s clinics are open not only to shelter guests, up to 1,000 people nightly, but also to people living on the streets who walk in seeking care.
Its dental clinic alone sees nearly 9,000 patients a year, Hood said.
“We haven’t seen it yet, but I expect in the coming days and weeks we’ll see more people coming through our doors looking for help,” he said. “They’re going to have to find help somewhere.” Hood said women experiencing homelessness are especially vulnerable when preventive care, including sexual and reproductive health services, becomes harder to access.
County officials said staffing impacts so far have been managed through reassignment rather than layoffs. Roughly 200 to 300 positions across the department have been eliminated amid funding cuts, officials said, though many were vacant. About 120 employees whose positions were affected have been reassigned; according to Mahajan, no one has been laid off.
The clinic closures come amid broader fiscal uncertainty. Mahajan said that due to the Trump administration’s “Big Beautiful Bill,” Los Angeles County could lose $2.4 billion over the next several years. That funding, he said, supports clinics, hospitals and community clinic partners now absorbing patients who previously went to the clinics that closed on Feb. 27.
In response, the L.A. County Board of Supervisors has backed a proposed half-cent sales tax measure that would generate hundreds of millions of dollars annually for healthcare and public health services. Voters are expected to consider the measure in June.

Mobile clinic brings mammograms to women on Skid Row
Sharon Horton stepped through the door of a sky-blue mobile clinic and onto a Skid Row sidewalk. She wore a yellow knit beanie, gold hoop earrings and the relieved grin of a woman who has finally checked a mammogram off her to-do list.
It had been years since her last breast cancer screening procedure. This one, which took place in City of Hope’s Cancer Prevention and Screening mobile clinic, was faster and easier. The staff was kind. The machine that X-rayed her breast was more comfortable than the cold hard contraption she remembered.
Relatively speaking, of course — it was still a mammogram.
“It’s like, OK, let me go already!” Horton, 68, said with a laugh.
The clinic was parked on South San Pedro Street in front of Union Rescue Mission, the nonprofit shelter where Horton resides. Within a week, City of Hope, a cancer research hospital, would share the results with Horton and Dr. Mary Marfisee, the mission’s family medical services director. If the mammogram detected anything of concern, they’d map out a treatment plan from there.

“It’s very important to take care of your health, and you need to get involved in everything that you can to make your life a better life,” said Horton, who is looking forward to a forthcoming move into Section 8 housing.
Horton was one of the first patients of a new women’s health initiative from UCLA’s Homeless Healthcare Collaborative at Union Rescue Mission. Staffed by third-year UCLA Medical School students and led by Marfisee, a UCLA assistant clinical professor of family medicine, the clinic treats mission residents as well as unhoused people living in the surrounding neighborhood.
The new cancer screening project arrives at a time of dire financial pressures on county public health services.
Citing rising costs and a $50-million reduction in federal, state and local grant and contract income, the Los Angeles County Department of Public Health on Feb. 27 ended services at seven of 13 public clinics that provide vaccines, tests and treatment for sexually transmitted diseases and other services to housed and unhoused county residents.
Although Union Rescue Mission’s own funding comes mainly from private sources and is less imperiled by public cuts, the 135-year-old shelter expects the need for its services to rise, Chief Executive Mark Hood said.
Even as unsheltered homelessness declined for the last two years across Los Angeles County, the unsheltered population on Skid Row — long seen as the epicenter of the region’s homelessness crisis — grew 9% in 2024, the most recent year for which census data are available.
For many local women navigating daily concerns over housing, food and personal safety, “their own health is not a priority,” Marfisee said.
Those whose problems have become too serious to ignore face daunting obstacles to care. Marfisee recalled one patient who came to her with a lump in her breast and no identification.
In order to get a mammogram, Marfisee explained, the woman first needed to obtain a birth certificate, and then a state-issued identification card. Then she needed to enroll in Medi-Cal. After that, clinic staff helped her find a primary care physician who could order the imaging test.
Given the barriers to preventative care, homeless women die from breast cancer at nearly twice the rate of securely housed women, a 2019 study found. Marfisee’s own survey of the mission’s female residents found that nearly 90% were not up to date on recommended cancer screenings like mammograms and pap smears, which detect early cervical cancer.
To address this gap, Marfisee — a dogged patient advocate — reached out to City of Hope. The Duarte-based research and treatment center unveiled in March 2024 its first mobile cancer screening clinic, a moving van-sized clinic on wheels that it deploys to food banks and health centers, as well as to companies offering free mammograms as an employee benefit.
“In true Dr. Mary fashion, she saw the vision,” said Jessica Thies, the mobile screening program’s regional nursing director. After working through some logistical hurdles, the mission and City of Hope secured a date for the van’s first visit.
The next challenge was getting the word out to patients. Marfisee and her students walked through the surrounding neighborhood, went cot to cot in the women’s dorm and held two informational sessions in December and January to answer patients’ questions.
At the sessions, the team walked through the basics of who should get a mammogram (women age 40 or older, those with a family history of breast cancer) and the procedure itself. (“Like a tortilla maker?” one woman asked skeptically after hearing a description of the mammography unit.)
The medical students were able to dispel rumors some women had heard: The test doesn’t damage breast tissue, nor do the X-rays increase cancer risk. Others questioned a mammogram’s value: What good was it knowing they had cancer if they couldn’t get follow-up care?
On this latter point, Marfisee is determined not to let patients fall through the cracks.
Thirteen patients received mammograms at the van’s first visit on Wednesday. Within a week, City of Hope will contact patients with their results and send them to Marfisee and her team. She is already mentally mapping the next steps should any patient have a situation that requires a biopsy or further imaging: working with their case manager at the mission, calling in favors, wrangling with any insurance the patient might have.
“It’ll be a good fight,” Marfisee said, as residents in the adjacent cafeteria carried trays of sloppy joes and burgers to their lunch tables. “But we’ll just keep asking for help and get it done.”

Can fire-resistant homes be sexy? ‘You be the judge,’ says this Palisades architect
At first glance, it looks like nothing more than a charming Spanish-revival, quintessentially Californian home — but this Pacific Palisades rebuild is constructed like a tank.
Every exterior wall of the steel-framed home is a foot-thick, fire-resistant barricade. The home is connected to a satellite fire monitoring service. Should a fire start in town, sturdy metal shutters descend to cover every window. An exterior sprinkler system can pump 40,000 gallons of water from giant tanks hidden behind the shrubs in the property’s yard. If the cameras and heat sensors around the house detect danger, the system can envelop the home in over 1,000 gallons of fire retardant and hundreds of gallons of fire-suppressing foam.
Palisades resident and architect Ardie Tavangarian is so confident in his design that he even asked the fire department if they could start a controlled fire on the property to test it all out. (They said no.)
Tavangarian built a career designing multimillion-dollar luxury homes in Los Angeles, but after the Palisades fire destroyed 13 of his works — including his family’s home — he found another calling: how to design a house that can handle what the Santa Monica Mountains throw at it. And how to do it quickly and affordably.
Water tanks form part of a backup water supply in a newly built fire-resistant home in Pacific Palisades.
“Nature is so powerful,” he said, sitting on a couch in the new house, which he built for his adult twin daughters. “We are guests living in that environment and expecting, ‘Oh, nature is going to be really kind to me.’ No, it’s not. It does what it’s supposed to do.”
Tavangarian watched the Jan. 1 Lachman fire from his property not far from here; a week later that fire rekindled, grew into the Palisades fire, and burned through his house. But the painful details of the fire — the missteps of the fire department, the empty reservoir — didn’t matter when it came to deciding how to rebuild, he said. The reality is, many fires have burned in these mountains. Many more will.
A sprinkler on the roof is part of a house-wide sprinkler system.
For the architect, who has spent much of his 45-year career designing for luxury, hardening a home against wildfire has brought a new kind of luxury to his homes: peace of mind.
It’s a sentiment that resonates with fire survivors: Tavangarian says he’s received considerable interest from other property owners in the Palisades looking to rebuild their houses.
The metal shutters and advanced outdoor sprinkler system are the flashiest parts of Tavangarian’s home hardening project, and the efficacy of these adaptations is still up for debate. Because the measures have not yet been widely adopted, there are few studies exploring how much or little they protect homes in real-world fires.
Architect Ardie Tavangarian inside the house he designed.
Anecdotal evidence has indicated the effectiveness of sprinklers can vary significantly based on the setup and the conditions during the fire. Extreme wind, for example, can make them less effective. Lab studies have generally found shutters can reduce the risk of windows shattering.
These measures aren’t cheap, either. Sprinkler systems can cost north of $100,000, for example. However, Tavangarian said when all was said and done, the home he built for his daughters cost around $700 per square foot — less than what Palisades residents said they expected to pay, but more than what Altadena residents expected for their rebuilds.
Tavangarian also hopes to see insurers increasingly consider the home-hardening measures property owners take when writing policies, which he said could potentially offset the extra cost in a decade or less. As he explored getting insurance for the new home, one insurer quoted him $80,000 a year. After he convinced the company to visit the property, it lowered the quote to just $13,000, he said.
The house includes metal heat shields that can drop down if a fire approaches.
The home also has essentially all of the other less flashy — but much cheaper and well-proven — home hardening measures recommended by fire professionals: The underside of the roof’s overhang is closed off — a common place embers enter a home. The roof, where burning embers can accumulate, is made of fire-resistant material. The windows, vulnerable to shattering in extreme heat, are made of a toughened glass. There is virtually no vegetation within the first five feet of the home.
When asked if he felt he had compromised on design, comfort or aesthetics for the extra protection — one of the many concerns Californians have with the state’s draft “Zone Zero” requirements that may significantly limit vegetation within five feet of a home — Tavangarian simply said, “You be the judge.”
