School choice in Sweden (and in Swedish), by Andersson and Roth

 Tommy Andersson and I wade into the school choice debate in Sweden in the Dagens Samhalle, arguing in favor of unified enrollment and the deferred acceptance algorithm. Google translate does a reasonable job of translation:

Professorer: Så kan skolvalet leda till minskad skolsegregation

Google Translate: "Professors: This is how school choice can lead to reduced school segregation

"If you seriously want to break school segregation, the choice of school needs to be maintained. But it is important that you choose the "right" method for allocating school places so that tactical school choices are eliminated, write professors Tommy Andersson and Alvin E Roth."

Scandia Transplant Kidney Exchange Program (STEP) takes its first steps

Here's a timely story of gift giving from the Karolinska University Hospital in Sweden:

Karolinska University Hospital part of the first kidney transplant program across Scandinavia – Scandia Transplant Kidney Exchange Program (STEP)
MON, DEC 23, 2019

"For the first time two kidney replacements have been performed involving donors and transplant patients who are part of the Scandinavian kidney exchange program STEP organized by Scandiatransplant.  The organization coordinates organ donations and transplants in Denmark, Estonia, Finland, Iceland, Norway and Sweden. During 2018 and 2019 Karolinska University Hospital performed and coordinated three STEP exchange programs with a total of six couples in cooperation with other hospitals in Sweden.
...
"Both kidney replacements performed during the autumn  involved two couples and  two other university hospitals in Scandinavia, says Lars Wennberg, Chief Physician and Patient Flow Manager Kidney Transplant at Theme Trauma and Reparative Medicine Karolinska University Hospital"

"STEP enables exchange of kidneys between medically accepted but immunologically incompatible donor-recipient pairs. A donor who wants to help a relative that needs a kidney donates anonymously to another unknown person in need of a kidney. In exchange, the next of kin receives a kidney from another recipient's kidney donor. Kidney changes can take place between two or more participating couples.

"Today, a total of 2261 people in the six countries that are included in STEP are waiting for a new kidney compared with 2208 in 2018. The ability to carry out kidney changes between the different countries means that we can shorten waiting times says Bo-Göran Ericzon, Chairman of Scandiatransplant and Professor of Transplantation Surgery Theme Trauma and Reparative Medicine Karolinska University Hospital.

"The necessary database to investigate immunological compatibility has been developed by Scandiatransplant, while the matching algorithm has been developed by Professor Tommy Andersson at the Department of Economics, Lund University in collaboration with Karolinska University Hospital."

Kidney exchange looks imminent in Sweden

Dagens Medicin (Today's Medicine) has the story:

Nytt koncept ska ge fler en ny njure
Snart startar ett nytt utbytesprogram av njurar som sträcker sig över hela Sverige. 
(GT: New concept will give more a new kidney
Soon a new kidney replacement program will start all over Sweden.)

"The exchange program has shown good results in other countries, so expectations are high, says Per Lindnér, Senior Assistant and Operations Manager at Transplant Center at Sahlgrenska University Hospital in Gothenburg.

"He is one of the initiators of the first Swedish renal exchange program. It can easily be described as a database matching system that couples potential donors and recipients within renal donation.
...
"Today, all of the country's centers for kidney transplants participate, that is, Sahlgrenska University Hospital, Karolinska University Hospital, Academic Hospital and Skåne University Hospital.

- Even hospitals in Norway and Denmark want to connect. But the idea is to start nationally and expand over time, "says Per Lindnér.
...
"The idea of ​​a national exchange program was born three years ago when Per Lindnér visited a seminar with Tommy Andersson, professor of discreet mathematics at Lund University.

Tommy Andersson talked about the mathematical background of an American renal exchange program created by Alvin Roth, former winner of Sveriges Riksbank's award in economics, to Alfred Nobel's memory.

When Per Lindnér wanted to introduce the same concept in Sweden, Tommy Andersson contributed with his knowledge, which forms the basis for the program."

Rethinking school competition in Sweden

There are calls for reforming Sweden's system of competition and school choice among lightly-regulated private schools. The Guardian has the story: Sweden urged to rethink parents' choice over schools after education decline--OECD recommends comprehensive reform including revised school choice arrangements and more effective regulation

"Sweden has been urged to halt the steep decline in the international ranking of its schools by taking action to limit parents’ and pupils’ right to choose.
report from the Organisation for Economic Co-operation and Development(OECD) recommends “a comprehensive education reform” to restore the Swedish system to its previous standards.
"Andreas Schleicher, director of the OECD’s education directorate, was scathing about the country’s “disappointing” performance, saying he had once viewed Sweden as “the model for education”.
“It was in the early 2000s that the Swedish school system somehow seems to have lost its soul,” he said at a press conference in Stockholm. “Schools began to compete no longer on delivering superior quality but on offering shiny school buildings in shopping centres, and I think that’s the issue we are really seeing.”
"The call for “revised school choice arrangements” will have resonance in the UK, where the coalition government’s programme to launch free schools funded by public money was in part inspired by Sweden.
"Since the 1990s, Sweden has allowed privately run schools to compete with public schools for government funds. Critics on the left blame the voucher system for declining results, saying it has opened the door for schools more interested in making a profit than providing solid education. Conservatives say students have been given too much influence in the classroom, undermining the authority of teachers.
"The OECD report says: “Student performance on the Programme for International Student Assessment (Pisa) has declined dramatically, from near the OECD average in 2000 to significantly below average in 2012. No other country participating in Pisa saw a steeper decline than Sweden over that period.”
...
"The report blamed the system of school choice for the failure of almost half of children from immigrant backgrounds (48%) to make the grade in mathematics.
"Rather than recommending rolling back Sweden’s system of free choice and competition in schools, however, it suggests that the country “revise school choice arrangements to ensure quality with equity”.
"That would involve limiting the independence of free schools from local education authorities by bringing in new national guidelines to allow municipalities to “integrate independent schools in their planning, improvement and support strategies”.
"The report also recommends helping disadvantaged families make better school choices, so that their children, as well as those from middle-class families, apply to the country’s more popular, better performing schools.
"Finally, it suggests that municipalities restrict the ability of some parents to choose their children’s schools by introducing “controlled choice schemes that supplement parental choice to ensure a more diverse distribution of students in schools”.

Womb transplants in Sweden (where surrogacy is illegal)

The NY Times has the story: Swedish Doctors Transplant Wombs Into 9 Women

 "STOCKHOLM — Nine women in Sweden have successfully received transplanted wombs donated from relatives in an experimental procedure that has raised some ethical concerns. The women will soon try to become pregnant with their new wombs, the doctor in charge of the pioneering project has revealed.

"The women were born without a uterus or had it removed because of cervical cancer. Most are in their 30s and are part of the first major experiment to test whether it's possible to transplant wombs into women so they can give birth to their own children.

"In many European countries, including Sweden, using a surrogate to carry a pregnancy isn't allowed.
...
"Some experts have raised concerns about whether it's ethical to use live donors for an experimental procedure that doesn't save lives. But John Harris, a bioethics expert at the University of Manchester, didn't see a problem with that as long as donors are fully informed. He said donating kidneys isn't necessarily life-saving, yet is widely promoted.

"Dialysis is available, but we have come to accept and to even encourage people to take risks to donate a kidney," he said.

"Brannstrom said the nine womb recipients are doing well. Many already had their periods six weeks after the transplants, an early sign that the wombs are healthy and functioning.
...
"None of the women who donated or received wombs has been identified. The transplants began in September 2012 and the donors include mothers and other relatives of the recipients.
...
"The transplant operations did not connect the women's uteruses to their fallopian tubes, so they are unable to get pregnant naturally. But all who received a womb have their own ovaries and can make eggs. Before the operation, they had some removed to create embryos through in-vitro fertilization. The embryos were then frozen and doctors plan to transfer them into the new wombs, allowing the women to carry their own biological children.
...
""If this had been possible when I was younger, no doubt I would have been interested," she said. Gimre, who has two foster children, said the only option for women like her to have biological children is via surrogacy, which is illegal in many European countries, including Norway and Sweden.
...
"The technique used in Sweden, using live donors, is somewhat controversial. In Britain, doctors are also planning to perform uterus transplants, but will only use wombs from dying or dead people. That was also the case in Turkey. Last year, Turkish doctors announced their patient got pregnant but the pregnancy failed after two months.

"Mats has done something amazing and we understand completely why he has taken this route, but we are wary of that approach," said Dr. Richard Smith, head of the U.K. charity Womb Transplant UK, which is trying to raise 500,000 pounds ($823,000) to carry out five operations in Britain.

"He said removing a womb for donation is like a radical hysterectomy but it requires taking a bigger chunk of the surrounding blood vessels to ensure adequate blood flow, raising the risk of complications for the donor. Smith said British officials don't consider it ethical to let donors take such chances for an operation that isn't considered life-saving.
...
"Doctors in Saudi Arabia performed the first womb transplant in 2000, using a live donor, but it had to be removed after three months because of a blood clot."
