Dr. Sam Yoon and a collaborator duplicated images across their research studies over many years. The collaborator has left Columbia.The chief of a cancer surgery division at Columbia University this week had five research articles retracted and a sixth tagged with an editor’s note, underscoring concerns about research misconduct that have lately bedeviled Columbia as well as cancer labs at several other elite American universities.With the latest retractions, the Columbia lab, led by Dr. Sam Yoon, has had more than a dozen studies pulled over suspicious results since The New York Times reported in February on data discrepancies in the lab’s work.The retracted studies were among 26 articles by Dr. Yoon and a more junior collaborator that a scientific sleuth in Britain, Sholto David, revealed had presented images from one experiment as data from another, a tactic that can be used to massage or falsify the results of studies.Dr. Yoon’s more junior collaborator, Changhwan Yoon, no longer works in the lab, Columbia said in response to questions on Wednesday. But the university has said little else about what, if anything, it has done to address the allegations.Since the Times article in February, Dr. Yoon’s name has been changed from Sam Yoon to S. Sunghyun Yoon on a Columbia website advertising surgical treatment options. Because of the change, the Columbia surgeon who is being promoted to many patients has a name that no longer matches the one Dr. Yoon used to publish his retracted studies. A Columbia hiring announcement from several years ago was also recently edited to change the rendering of Dr. Yoon’s name, according to web page archives.Columbia said that faculty members were responsible for any name changes on departmental web pages. The university declined to comment on the retractions. Memorial Sloan Kettering Cancer Center, where Dr. Yoon worked when much of the questionable research was done, also declined to comment, saying only that it reviews such cases.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

Lewis, the host of the 1990s MTV show “Hot Zone,” tried to fight her illness without undergoing a double mastectomy. She says she is responding well after resuming treatment.The former MTV V.J. Ananda Lewis said in a CNN round-table discussion that was posted online on Tuesday that her breast cancer, which she first learned she had in 2019, metastasized last year and had reached Stage 4.In a phone interview with The New York Times on Wednesday, Lewis, 51, said that she had since resumed treatment and was feeling much better. “I’ve turned it around really beautifully,” she said.Lewis first became recognizable in the 1990s as a host of “Teen Summit,” a long-running weekly live show on BET that aimed to speak to Black teenagers about current issues (Lewis interviewed Hillary Clinton, who was then the first lady, on the program in 1996). She went on to host “Hot Zone,” an MTV show in which she interviewed stars and gave style advice. The Times, in a 1999 profile, described her as one of MTV’s most popular stars and “the hip-hop generation’s reigning It Girl.”Stage 4 breast cancer means that the cancer cells have spread beyond the breast, often traveling to the bones, the lungs and the liver. It can be treated with tools like chemotherapy and hormone therapy, but it is considered incurable. Breast cancer is the second most common cancer among women in the United States and a leading cause of death from cancer among women globally.In the round-table — with the CNN correspondent Stephanie Elam, Lewis’s best friend since they met at Howard University in the 1990s, and the CNN anchor Sara Sidner, who had a double mastectomy this year after learning that she had Stage 3 breast cancer — Lewis said that she had decided not to get a double mastectomy despite her doctors’ recommendation in early 2019, when she first discovered the lump and learned she had Stage 3 breast cancer.She sought conventional care after receiving the initial diagnosis, speaking to “the right and best oncologists, the breast surgeons,” she said on Wednesday. As she told Elam, “I decided to keep my tumor and try to work it out of my body a different way.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

Lucy Letby gave a baby 10 times the prescribed dose of morphine “in error” two years before her killing spree began, a public inquiry has heard.

An urgent review is needed to make sure people in England can get weight loss jabs such as Wegovy and Mounjaro on the NHS, top experts warn. It comes a day after the prime minister said such injections could boost Britain’s economy by getting obese unemployed people “back into work”. More than 200 doctors and specialists have now written to the health secretary to say how stretched NHS obesity treatment services face unprecedented demand from patients wanting these drugs.They warn the injections are only part of what should be a wider package of non-stigmatising care. They say the government must fix some fundamentals issues in NHS obesity services – chronic underfunding, workforce challenges and unequal access to care. The letter to Wes Streeting is being sent by the Obesity Health Alliance (OHA), which represents health charities and medical royal colleges, and has compiled a report.It says some patients can wait up to five years for specialist support, and that some services are so overstretched they have closed their waiting lists entirely.The OHA wants to see equitable access for obesity treatments, including weight loss injections.There have been reports of global stock shortages and, currently in the UK on the NHS, the injections can only be offered through specialist weight-management services. Some patients go private, but many others miss out, warns the OHA. According to the OHA, about four million people in England are eligible for Wegovy, but NHS projections estimate that by 2028, fewer than 50,000 people a year would get the treatment. Katharine Jenner, director of the OHA, said the weight loss jabs were effective, but that was not the whole picture.”Even if you are taking the jabs you still need to have extra care and support around it. You still need to be doing exercise and have dietary advice as well and that’s not currently there.”There is also concern about who is getting access to this drug. We need to make sure that we are prioritising access based on greatest clinical need and not based on any other factors.”She added that the OHA had heard about people that had a right to access treatment services due to their excess weight being turned away.”They’re having to seek private treatment and they’re not getting the care and support package that they’d be expecting to get if you had any other sort of condition,” she said.”We need to have a review of existing NHS services to identify cases of really good best practice and identify those challenges that exist all over the place.” The upcoming approval for the NHS to use another injection, called Mounjaro, dubbed by some as the King Kong of weight loss jabs for how well it appears works in trials, is expected to place even more pressure on the system, the report warns. Alfie Slade, government affairs lead at the OHA, said: “The new weight loss drugs represent a breakthrough in treatment, giving hope to the millions of people struggling to manage their weight, but they also expose the weaknesses in our current obesity services. “Without urgent government intervention, we will fail to meet the needs of millions of patients, leading to greater health inequalities.”Despite the benefits, health experts also caution that Wegovy and Mounjaro, which mimic a hormone that makes people less hungry, are not a quick fix. Patients must still exercise and watch what they eat.Users can put weight back on once they stop the medication. And, as with any drug, there can be side effects.Doctors are concerned about the growing numbers of patients they are seeing with complications from taking weight loss drugs bought online without clinical supervision.In many cases people might not actually be getting what they think they are, which can be very dangerous.Public health measures to help prevent obesity problems in the first place, such as improving the nation’s diet and helping children get enough exercise, are also vital, says the OHA. NHS England said it was working with the government and industry to develop new kinds of services which mean approved treatments can be rolled out safely, effectively and affordably.A spokesperson said weight loss drugs would be “transformative” and, alongside NHS early prevention initiatives, “help more people to lose weight and reduce their risk of killer conditions like diabetes, heart attack and stroke”.A Department of Health and Social Care spokesperson said obesity “costs the NHS more than £11bn a year and it also places a significant burden on our economy”.”With obesity-related illness causing people to take more days off sick, obesity drugs can be part of the solution,” they said.The spokesperson also said junk-food advertising restrictions and a ban on the sale of high-caffeine energy drinks to children would help tackle the “obesity crisis”.
