'Very unusual': 68-year-old woman with new blood type found; compatible only with herself
.
Scientists have discovered a
new blood type
in a 68-year-old woman from the French overseas region of Guadeloupe. The blood group has been named 'Gwada Negative' and is only found in one woman across the globe.
Thierry Peyrard, a medical biologist at the EFS, said, "She is the only person in the world who is compatible with herself', as reported by AFP. Peyrard explained that the woman got her blood type from both her parents, as each of them carried the mutated gene. He said that such an instance was 'very unusual'.
The research team that made this discovery announced their findings in a presentation at the International Society of Blood Transfusion's Congress in Milan, which concluded on June 4. The research team had initially met the woman in Paris in 2011 when she was undergoing routine checkups before a surgery, when doctors could not ascertain her blood group, reported the French blood establishment (EFS).
At the time, research methods were not advanced enough to solve the case, which remained unsolved for eight years.

In 2019, researchers used
high-throughput gene sequencing
, a method that allows faster and deeper DNA analysis, to re-examine the woman's blood. Over the next two years, they carefully studied her full genetic makeup.
The woman's strange lab test results ultimately led to the discovery of a mutation in a gene called PIGZ, which changes the way proteins anchor to the surface of blood cells, as reported by LiveScience. Till now, EFS has recognised 47 blood group systems.
The ABO blood group systems which was initially identified by Austrian-American biologist Dr Karl Landsteiner, is the first and the most familiar blood group system. DNA sequencing in the latest years has accelerated the discovery of new blood groups in the recent years.
Blood group systems play a crucial role in safe blood transfusions, as the body rejects antigens that it perceives as foreign. The most common ABO blood typing system describes whether people have both the antigens of 'A', 'B', one of them or neither of them.
In the ABO system, individuals with both A and B antigens (AB blood type) can recieve blood from any blood group as their body recognises both the antigens. On the other hand, people with O blood type can only receive blood from other O-type donors as they do not have A or B antigens.
Peryard and his colleagues are now aiming to find other people with the same blood group as "Discovering new blood types means offering patients with rare blood a better level of care," said the EFS statement.

"I need to live every darn day to the fullest": New freedom for former tennis star Chris Evert after ovarian cancer ordeal
Chris Evert (via Getty Images) Tennis great Chris Evert , a retired world No. 1 and 18-time Grand Slam singles titlist, recently shared that her battle with ovarian cancer has radically transformed her perspective on life and self-expression. Diagnosed twice with stage 1 ovarian cancer, Chris Evert is now cancer-free and is leveraging her platform to promote awareness, genetic screening, and living life on her terms. Chris Evert speaks out about her fight with cancer and how it redefined her voice and purpose Chris Evert's experience with ovarian cancer was defined by tragedy, caution, and strength. Having already lost her sister Jeanne to the disease, Chris Evert was tested genetically and determined to be a carrier of the BRCA-1 mutation. After a preventative hysterectomy in 2022, physicians found stage 1 ovarian cancer through routine pathology. Although the cancer came back, it was once more detected early on and effectively treated. Now 69, Chris Evert is in remission for the second time. "Before this period of my life, I used to be wary of image and speaking out. Now I just say what I want to say, and that is an attitude that sets you free. If I am well informed and educated on a subject and I have an opinion, then I like to use my voice to speak out," Evert recently explained. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like India: Jewelry On Sale For Half Price (See Price List) Luxury Jewelry | search ads Undo That's the attitude that's given her not only confidence but also a mission: empowering women to know their risk factors, to get genetic testing, and to take their health into their own hands. How an unexpected cancer diagnosis finally set Chris Evert free: "I used to be wary... Now I just Although Evert promotes early awareness, experts warn against a misconception: that there is an "early test" for ovarian cancer. As reported by the Ovarian Cancer Research Alliance (OCRA), no screen is yet effective in detecting the disease in its earliest stages among the general population. Rather, professionals highlight genetic testing and preventive surgeries, particularly for high-risk patients with BRCA mutations. Dr. Gillian Hanley, associate professor at the University of British Columbia, points to the singularity of Evert's case: 'She would never have been symptomatic,' says Hanley. 'There's no screening method that would have picked that up. The only reason that cancer was diagnosed is because her fallopian tubes were removed and then they were very, very carefully analyzed by a pathologist… and that doesn't occur outside of the case of a BRCA mutation. ' No early detection for ovarian cancer—but knowledge is power Ovarian cancer is uncommon, occurring in approximately 1 in 87 women during their lifetime, but tends to be diagnosed late because it has insidious symptoms. As opposed to popular belief, the CA-125 blood test and transvaginal scans are not effective for early detection. A UK clinical trial in 2021 on a large population showed that existing screening practices do not lower mortality. This is why medical experts now focus on prevention through genetic testing and risk-reducing surgeries like salpingectomy (removal of the fallopian tubes), especially during unrelated pelvic surgeries. 'So again, we're not saying that your regular woman on the street needs to go in and have this elective surgery,' said Sarah DeFeo of OCRA. 'But we know that hundreds of thousands of women are having surgery every year anyway, for a different reason, where they could take the opportunity to take out their tubes at the same time, potentially. It's something that they should talk to their doctor about, and it's something that doctors should be thinking about. ' DeFeo also encourages women to realize that family background counts on both sides. BRCA mutations are also inherited from fathers, so it is important to know your full genetic history. "It does change you when you have a battle like this and I do think about whether my cancer will come back from time to time, but what I think about more is that I need to live every darn day to the fullest. You know, I'd better start doing only things that I want to do and only things that make me happy. That's the way I think now," Evert said. "When you have lived through an experience like this, you appreciate that every day is precious. You just don't know what's around the corner and the reality is you have no control over it. So live every moment. This feels like a second chance for me, no doubt about it. Sometimes you have to sink to the lowest depths and get to a point where you wonder whether you will get through something like cancer to change your mindset," she said.

Israeli strikes kill at least 34 in Gaza amid ceasefire talks, say health staff
At least 34 people were killed across Gaza by Israeli strikes, health staff say, as Palestinians face a growing humanitarian crisis in Gaza and ceasefire prospects inch closer. The war has killed over 56,000 Palestinians so far, according to Gaza's Health Ministry.(AFP) The strikes began late Friday and continued into Saturday morning, among others killing 12 people at the Palestine Stadium in Gaza City, which was sheltering displaced people, and eight more living in apartments, according to staff at Shifa hospital where the bodies were brought. Six others were killed in southern Gaza when a strike hit their tent in Muwasi, according to the hospital. The strikes come as U.S. President Donald Trump says there could be a ceasefire agreement within the next week. Taking questions from reporters in the Oval Office Friday, the president said, 'we're working on Gaza and trying to get it taken care of.' An official with knowledge of the situation told The Associated Press that Israel's Minister for Strategic Affairs, Ron Dermer, will arrive in Washington next week for talks on Gaza's ceasefire, Iran and other subjects. The official spoke on condition of anonymity because they were not authorized to speak to the media. Talks have been on again off again since Israel broke the latest ceasefire in March, continuing its military campaign in Gaza and furthering the Strip's dire humanitarian crisis. Some 50 hostages remain in Gaza, fewer than half of them believed to still be alive. They were part of some 250 hostages taken when Hamas attacked Israel on Oct. 7, 2023, sparking the 21-month-long war. The war has killed over 56,000 Palestinians, according to Gaza's Health Ministry, which does not distinguish between civilians and combatants. It says more than half of the dead were women and children. There is hope among hostage families that Trump's involvement in securing the recent ceasefire between Israel and Iran might exert more pressure for a deal in Gaza. Israeli Prime Minister Benjamin Netanyahu is riding a wave of public support for the Iran war and its achievements, and he could feel he has more space to move toward ending the war in Gaza, something his far-right governing partners oppose. Hamas has repeatedly said it is prepared to free all the hostages in exchange for an end to the war in Gaza. Netanyahu says he will only end the war once Hamas is disarmed and exiled, something the group has rejected. Meanwhile hungry Palestinians are enduring a catastrophic situation in Gaza. After blocking all food for 2 1/2 months, Israel has allowed only a trickle of supplies into the territory since mid-May. Efforts by the United Nations to distribute the food have been plagued by armed gangs looting trucks and by crowds of desperate people offloading supplies from convoys. Palestinians have also been shot and wounded while on their way to get food at newly formed aid sites, run by the American and Israeli backed Gaza Humanitarian Foundation, according to Gaza's health officials and witnesses. Palestinian witnesses say Israeli troops have opened fire at crowds on the roads heading toward the sites. Israel's military said it was investigating incidents in which civilians had been harmed while approaching the sites.
