Designing privacy (differential privacy) at the Institute for Advanced Study


Differential privacy disentangles learning about a dataset as a whole from learning about an individual data contributor. Just now entering practice on a global scale, the demand for advanced differential privacy techniques and knowledge of basic skills is pressing. This symposium will provide an in-depth look at the current context for privacy-preserving statistical data analysis and an agenda for future research. This event is organized by Cynthia Dwork, of Microsoft Research, with support from the Alfred P. Sloan Foundation.
Speakers include:
Helen Nissenbaum, Cornell Tech and NYU
Aaron Roth, University of Pennsylvania
Guy Rothblum, Weizmann Institute
Kunal Talwar, Google Brain
Jonathan Ullman, Northeastern University

And in other election news...marijuana

What can I say? It looks like we may need it...
Californians Legalize Marijuana in Vote That Could Echo Nationally

"California, Massachusetts and Nevada legalized marijuana on Tuesday in what advocates said was a reflection of the country’s changing attitude toward the drug.

Leading up to the election, recreational marijuana use was legal in four states: Alaska, Colorado, Oregon and Washington, along with Washington, D.C.

With the addition of California, Massachusetts and Nevada, the percentage of Americans living in states where marijuana use is legal for adults rose above 20 percent, from 5 percent."

A seller's guide to the U.S. market for sperm

The NY Times has some advice for potential sellers...

10 Things to Know About Being a Sperm Donor

"Your odds of getting into Harvard or Stanford are higher than your chances of being accepted as a donor at the major sperm banks.

California Cryobank and Fairfax Cryobank, the nation’s two largest sperm banks, take only about one in 100 applicants. Some deal-breakers: a low sperm count, an iffy health history or sperm that don’t do well after freezing.

If you’re short, forget about it.

...

You’ll never know how many children you have fathered.

There’s no legal limit, but the biggest sperm banks have policies that one donor’s sperm will not be allowed to sire children for more than 25 to 30 different “family units.” But some families may have two or three children with the donor’s sperm, and others may not report a birth, so they would not be counted in that limit. Some men who have joined the Donor Sibling Registry, a site where donors and their children can connect, have been surprised and disturbed to discover that they have dozens of offspring.

You may or may not get to meet them.

Sperm donors usually have the option to remain anonymous, or to agree that the children can get in touch when they turn 18. There has been a growing recognition of children’s rights to know their genetic parents — and recently a trend toward donor willingness to be identified. Even anonymous donors are increasingly being identified by curious children as genetic testing becomes cheaper and more common."

In Britain, National Sperm Bank stops recruiting donors

The Telegraph has the story: National Sperm Bank stops recruiting donors after just two years

"The National Sperm Bank (NSB) was a joint project run by the National Gamete Donation Trust (NGDT) and the Birmingham Women’s Fertility Centre and launched in October 2014 with a £77,000 grant from the Department of Health.
It was hoped the service would plug the gap in the shortage of donors and prevent couples being forced to look for sperm from overseas.
The bank hoped to be self-sufficient within a year but because the full donor process takes up to 18 months they were unable to generate enough income to keep going.
Although they only managed to recruit seven viable donors, experts said it was the business model that proved their ultimate downfall.
...
"For every 100 men who enquire about being a donor, only 4 or 5 are ultimately accepted.
The Human Fertilisation and Embryology Authority estimate that 2,000 children are born every year in the UK using donated eggs, sperm or embryos and there are around licensed UK clinics performing sperm donor insemination.
But the majority of clinics are based in London and the south-east of England and treatment can be expensive. The cost of donor sperm from the UK's largest sperm bank, the London Sperm Bank, is currently £950. In contrast the National Sperm bank was proposing to charge £300 per insemination.
...
"The bank has also suffered because since 2005 the children of donors have a right to learn the identity of their fathers when they turn 18. The numbers of men willing to donate sperm has fallen dramatically since their anonymity was removed."

La maga de riñones: The kidney conjurer (a poem about kidney exchange by Marisol Robles)

In kidney exchange, surgeons (and even economists) are important, but transplant coordinators are the hidden heroes and heroines. Here's a poem by the Mexican poet Marisol Robles (who last week received a kidney in a global kidney exchange chain organized by the Alliance for Paired Donation) in honor of Susan Rees, the APD's transplant coordinator.  The Spanish poem is translated by her husband Cuauhtémoc.


La maga de riñones, by Marisol Robles


 You can follow Marisol Robles on her blog Diario de la sed (Diary of thirst), which recounts her progress. (Google translate does a pretty good job on most of her posts...Kidney patients on dialysis are thirsty, since they have to time their drinking to their dialysis sessions...)

P.S. Susan Rees, the nurse transplant coordinator celebrated in the poem, is also the wife of Mike Rees, the founder of the APD, who organized the very first non-simultaneous kidney exchange chain.

A (first) three way kidney exchange in New Zealand

Minister welcomes NZ's first three way kidney exchange
RACHEL CLAYTON AND LAURA WALTERS, October 24 2016


"A three-way kidney transplant exchange has been carried out in New Zealand for the first time.

The process involved taking three incompatible donor and recipient pairings and matching them with each other to allow a transplant to take place.

The transplants took place in Canterbury and Auckland earlier this month "



"Organ donation in New Zealand has risen over the past 10 years, from 29 dead organ donors in 2005 to 53 in 2015.

A Catholic priest in Kerala India helps organize kidney transplant chains

Business of Kidneys: Kerala priest facilitates domino transplants for over fifty patients

"Nephrologists at New Delhi's All India Institute of Medical Sciences estimate that five lakh people live with failed kidneys in India at a time. A Lancet study revealed that just 10 per cent of patients suffering from kidney failure have access to dialysis, and 70 per cent of those starting dialysis die or discontinue treatment within the first three months due to the high cost of the treatment.
"The Catholic priest in Kerala's Thrissur district mooted a chain of kidney exchanges with a voluntary donor offering a kidney to a needy person, and a relative of this recipient in turn donating his/her kidney to another person, and so on. This system is known as 'Domino Transplant'. In the last five years, 56 people have been part of such kidney exchange chains, linking disparate people from industrialists to truck drivers in a chain. Two hundred others have pledged to join the chains when compatible donor-recipient pairings are established. Fr Davis Chiramel says the numbers could have been higher but for the poor medical infrastructure it could not."

Public appeals for organ donors by patients in Canada

The Ottawa Sun has the story: After Eugene Melnyk, transplant surgeons OK public appeals for living organ donors

"Eighteen months after a donated liver from a stranger saved the life of Ottawa Senators owner Eugene Melnyk, his case has helped prompt Canadian transplant officials to accept that public pleas for living organ donors are ethical, legal and even beneficial, under the right circumstances.

Melnyk was one of two high profile cases in 2015 (the other was the family of twin girls from Eastern Ontario, the Wagners) in which public pleas were made for a liver donor. Hundreds of people answered the call to donate parts of their livers to save Melnyk’s life. His eventual transplant was a success and both Melnyk and his anonymous donor — who was described only as a Senator’s fan — recovered. Little Binh Wagner also recovered from a successful liver transplanted from an anonymous donor (her twin sister received part of their father’s liver).

The cases raised ethical questions about the fairness of public pleas that tend to favour those with more compelling stories over others legitimately waiting for an organ transplant. They also highlighted the fact that there is no national policy on organ solicitation, a gap the Canadian Society of Transplantation, the Canadian National Transplant Research Program and the Canadian Blood Services hope to close with guidelines released this week.

The guidelines acknowledge that ethical questions remain, but note that the gap between supply and demand of organs and the availability of public platforms to easily make such pleas means those questions are going to continue.

Dr. Atul Humar, medical director of transplant at the University Health Networks in Toronto where Melnyk’s and Binh Wagner’s transplants were performed, said public solicitations are increasing, mainly because of easy access to social media and a shortage of organs to transplant. Earlier this year, Gianna-Lynn Favilla, an eight-year-old Russell girl, received a life-saving liver transplant after the family made a desperate public plea on her behalf. The donor was a neighbour and the father of Gianna-Lynn’s best friend.

At the end of 2014, 4,514 patients (3,473 for a kidney and 507 for a liver) were waiting for an organ in Canada. During the same year, 2,356 transplant procedures were performed and 278 patients died while on the waiting list."
...
"The issue has caused some soul searching among transplant officials in Canada and around the world. Some institutions have refused to transplant organs obtained from public solicitation and the practice is banned in Australia. Recently, European transplant officials came to a similar conclusion as the Canadian guidelines: “As long as donor shortage persists, we should not condemn patients, who do not have a live kidney donor, or only have a very slim chance of finding a suitable donor when they decide to publicly solicit for a live donor.”

Tissue transplants and tissue banks

Solid organ donation gets more press, but tissue transplants and medical devices made from human tissue are big business. Here's a profile of a Virginia organ and tissue bank:
Hearts, lungs and kidneys recovered by LifeNet Health get the most attention, but tissue is the larger player, By Elizabeth Simpson, The Virginian-Pilot

"[Tissues] are used in a wide variety of ways: to reconstruct breasts after cancer treatment. To repair joints in knees and ankles. To treat wounds of diabetics suffering from foot ulcers. To bridge bones in spinal fusion surgeries.

Douglas Wilson, LifeNet Health’s executive vice president, puts it into perspective this way: In one month, LifeNet provides solid organs for 40 to 60 patients, most of whom live in Virginia. But in terms of tissue transplants, some 40,000 patients a month across the globe receive LifeNet bioimplants.

That branch powers the growth of LifeNet, a nonprofit in the burgeoning Princess Anne bioscience corridor with operating revenue that topped $200 million last year. Solid organ recoveries went from 385 in 2011 to 467 last year, and tissue transplants from 389,000 to 462,000.

LifeNet is one of 58 organ procurement organizations in the country, and one of more than 100 accredited tissue banks. By law, companies can’t sell human tissue, but they can charge fees for recovery, processing, storing and distributing tissue.

And LifeNet fiercely guards its techniques. In 2014, the organization took a rival tissue transplant company to court, saying it used LifeNet’s patented technology to preserve tissue grafts and bone.

A federal jury awarded nearly $35 million to LifeNet, a finding that was appealed by the New Jersey-based LifeCell Corp., but upheld by a federal appeals court last month.

Wilson expects the growth in the tissue transplant field – which includes both for-profits and nonprofits – to continue, considering a few trends:

More older people will experience worn-out knees, hips, tendons and spinal discs. Obesity rates will fuel more diabetes cases with ulcers that require tissue transplants. And there’s the explosive field of regenerative medicine, which focuses on replacing and regenerating human cells.

“We’re sending tissue to every state and 30 countries,” Wilson said. “Allografts are used in almost every hospital in the U.S.”

When technical specialist Craig Wolf came to work at LifeNet 28 years ago, he was one of 44 employees. The number now? Nearly 900. The company has 600 products, 60 patents and branch offices in Washington and Florida."

Organ donation in Wales (where registration is now opt out)

Here's an early, optimistic report:
Organ donation rates have risen since the 'opt-out' system was introduced in Wales

"There has been a rise in the number of organs being donated by people in Wales since the new “opt out” law was put in place last year.

New figures from the Organ Donation Annual Report 2016 have revealed a 7% increase in the number of deceased donors donating in Welsh hospitals, up from 60 in 2014-15 to 64 in 2015-16.

Similarly, the number of donors after brain death increased by 13% to 36, while the number of donors after circulatory death remained the same at 28."

Matching patients to clinical trials

There are lots of clinical trials that a patient might be eligible for, but with many constraints on eligibility it isn't trivial to match patients to trials.
Modernhealthcare.com has a story:
 Providers turn to technology to match patients to clinical trials

"Clinical trial recruitment has long been one of the most challenging areas of drug development, with the potential to add significant costs and delays. And as the medical field gains a greater understanding of cancer pathways and genomics, finding patients for these trials has become only more complex.

Now a number of technology companies are aiming to solve that problem by helping providers identify clinical trials for patients who might qualify.
...
"At any given time, there are as many as 180,000 ongoing clinical trials, each with its own specific inclusion and exclusion criteria. Meanwhile, physicians have only 15 minutes, in many cases, to explore these options with a patient"

New York City high school admissions, signaling 'demonstrated interest,' in The Atlantic

High school admissions in NYC may end with a (well designed) deferred acceptance algorithm, but the process starts long before students and some schools submit their preference lists. The Atlantic writes about how it is hard to form preferences over high schools, and to signal them to the schools through 'demonstrated interest'...

Broken Promise of New York City's High-School Admissions System
Its high-school fair is designed to give attendees a leg up in the application process—but that’s not always the case

Time: 18:30 - 20:00
Venue: LSE Old Theatre
Speaker: Professor Raj Chetty
In this series of lectures, Raj Chetty will discuss findings from the Equality of Opportunity Project, which uses big data to develop new answers to this important and timely policy question. The presentation will show how children's opportunities to climb the income ladder vary substantially depending upon where they grow up.It will then identify factors that contribute to this geographic variation in opportunities for upward mobility. The talks will conclude by offering policy lessons for how social mobility and economic opportunity can be increased in the next generation.
Lecture 1: The Geography of Intergenerational Mobility
(Chair: Prof. Steve Machin, CEP Director)
Lecture 2: Policies to Improve Upward Mobility
