What to know about chronic venous insufficiency — President Tump's health diagnosis
What is chronic venous insufficiency?
"CVI is when the veins of the body do not work well," said Dr. Mimmie Kwong, assistant professor of vascular surgery at UC Davis Health, when veins cannot transport blood effectively, causing it to pool, especially in the legs.
CVI is one of the most common vein problems in the U.S. and worldwide, affecting "about one in three adults in the United States," Kwong said.
That translates to more than 30 million people in the U.S., most often older adults, according to Dr. Ali Azizzadeh, a professor and director of Vascular Surgery at Cedars-Sinai and associate director of the Smidt Heart Institute. He noted the condition is more common in women.
As people age, the veins, such as in their legs, may have a harder time returning blood to the heart, he said.
What causes CVI?
The valves in the veins of the legs are supposed to keep blood moving in one direction: back toward the heart. But when those valves are damaged or weakened, they can stop working properly, leading blood to flow backward and collect in the lower legs.
Individuals who stand or sit for extended periods, or those with a family history of vein issues, may be at a higher risk of developing the condition.
'When the calf muscles are active, they pump the veins that return blood from the legs to the heart,' Azizzadeh explained. 'With prolonged inactivity of those muscles, blood can pool in the legs.'
What does CVI feel like?
While CVI isn't always painful, it can cause discomfort that worsens as the day goes on.
The mornings may feel the best: 'The legs naturally drain while you are lying down and sleeping overnight,' said Azizzadeh, 'so they will typically feel lightest in the morning.'
As the day progresses and blood starts to pool, people with CVI may experience swelling, heaviness, aching or a dull pain in their legs. The symptoms tend to worsen after prolonged periods of standing or sitting.
If swelling worsens, thickening, inflammation or dry skin can result, with more severe cases developing wounds that do not heal and can even result in amputation, Kwong said.
How is CVI treated?
Ttreatment is more manageable when problematic veins are closer to the surface of the skin, Kwong said. It's more problematic when deep veins are affected.
The first line of treatment is usually simple lifestyle changes. 'We suggest CEE: compression, elevation, and exercise,' Azizzadeh said. Wearing compression stockings can help push blood out of the legs; elevating the legs allows gravity to help drain blood from the legs toward the heart, and regular walking forces calf muscles to pump blood throughout the body.
For people with more serious cases, doctors may recommend a minimally invasive procedure that uses heat to seal off the leaky veins. Common treatments include ablation techniques, surgical removal of veins (phlebectomy), or chemical (sclerosant) injections. "All of these therapies aim to cause the veins to shut down, so they no longer cause the CVI," Kwong said.
In President Trump's case, the condition appears to be mild and manageable. His doctors emphasized there was no cause for concern and that he remains in good overall health. But for millions of Americans living with CVI, recognizing the symptoms and knowing how to manage them can make a big difference in day-to-day comfort and long-term well-being.

Ob Hospitalist Group Expands Access to High-Risk Pregnancy Care with Launch of Obtelecare
Newly branded telehealth solution builds on OBHG's longstanding commitment to high-risk pregnancy care in hospitals and clinics nationwide GREENVILLE, S.C., Aug. 4, 2025 /PRNewswire/ -- Ob Hospitalist Group (OBHG), the nation's largest and only dedicated provider of comprehensive obstetric solutions, is proud to introduce Obtelecare, a newly branded virtual maternal–fetal medicine (MFM) service. As an expansion of OBHG's high-risk pregnancy capabilities, Obtelecare provides hospitals, health systems and clinics with continuous access to MFM care through telephonic support, virtual consultations, and remote monitoring. This enhanced offering strengthens OBHG's commitment to improving access to high-risk pregnancy care, especially in communities facing provider shortages or coverage gaps. Currently, there are fewer than 2,500 MFMs serving the entire country, creating significant gaps in care and limited availability of MFM services. At the same time, risk factors for high–risk pregnancies, such as hypertension, diabetes, obesity, and advanced maternal age, are on the rise. Obtelecare is a telehealth solution that extends the reach of MFM specialists, enabling earlier interventions through virtual consultations. The service allows MFMs to collaborate with the patient, OB–GYNs, hospitalists, nurses, and other onsite providers to develop a care plan in real time, which is then deployed by providers onsite. "Obtelecare represents the next evolution of our mission to ensure every mother has access to the level of care she needs, when she needs it," said Nick Sacco, President and Chief Operating Officer of OBHG. "While the name is new, Obtelecare builds on the high-risk care we've long provided to the communities we serve. This launch represents a meaningful investment in expanding our care model to address a critical gap in maternal-fetal medicine access. Building on almost 20 years of expanding access to high–quality obstetric and midwifery care through our proven OB hospitalist model, we're now extending our services to include virtual maternal–fetal medicine. By breaking down geographic barriers in communities across the U.S., Obtelecare will open doors to MFM expertise in markets that have historically struggled to recruit specialists—ultimately leading to safer pregnancies, healthier babies, and stronger communities." Available nationwide, the program offers a fully customizable and scalable solution for health systems, hospital and clinics. Built on OBHG's proven capabilities, it enhances care by enabling earlier interventions and improving coordination between onsite clinical teams and remote MFM experts, all while integrating smoothly into existing workflows to support better outcomes for high-risk pregnancies. "The rise in high–risk pregnancies has led to a growing demand for MFM specialists, outpacing the current supply of clinicians and creating significant gaps in the availability of MFM services," said Rebecca Flack, Senior Vice President of Telehealth at OBHG. "For complex pregnancies, timely access to an MFM isn't just beneficial — it can be lifesaving. With Obtelecare, Ob Hospitalist Group is closing critical gaps in care and bringing expert–level support to patients and providers in underserved or under-resourced areas." For more information about Obtelecare and how health systems can partner with OBHG, visit About ObtelecareObtelecare, part of Ob Hospitalist Group's comprehensive suite of obstetric solutions, delivers real-time collaboration between onsite clinicians and maternal-fetal medicine (MFM) specialists through advanced telehealth technology.

Scientists say they have solved the mystery of what killed more than 5 billion sea stars
Sea Star Disease WASHINGTON (AP) — Scientists say they have at last solved the mystery of what killed more than 5 billion sea stars off the Pacific coast of North America in a decade-long epidemic. Sea stars – often known as starfish – typically have five arms and some species sport up to 24 arms. They range in color from solid orange to tapestries of orange, purple, brown and green. Starting in 2013, a mysterious sea star wasting disease sparked a mass die-off from Mexico to Alaska. The epidemic has devastated more than 20 species and continues today. Worst hit was a species called the sunflower sea star, which lost around 90% of its population in the outbreak's first five years. 'It's really quite gruesome,' said marine disease ecologist Alyssa Gehman at the Hakai Institute in British Columbia, Canada, who helped pinpoint the cause. Healthy sea stars have 'puffy arms sticking straight out,' she said. But the wasting disease causes them to grow lesions and 'then their arms actually fall off.' The culprit? Bacteria that has also infected shellfish, according to a study published Monday in the journal Nature Ecology and Evolution. The findings 'solve a long-standing question about a very serious disease in the ocean," said Rebecca Vega Thurber, a marine microbiologist at University of California, Santa Barbara, who was not involved in the study. It took more than a decade for researchers to identify the cause of the disease, with many false leads and twists and turns along the way. Early research hinted the cause might be a virus, but it turned out the densovirus that scientists initially focused on was actually a normal resident inside healthy sea stars and not associated with disease, said Melanie Prentice of the Hakai Institute, co-author of the new study. Other efforts missed the real killer because researchers studied tissue samples of dead sea stars that no longer contained the bodily fluid that surrounds the organs. But the latest study includes detailed analysis of this fluid, called coelomic fluid, where the bacteria Vibrio pectenicida were found. 'It's incredibly difficult to trace the source of so many environmental diseases, especially underwater,' said microbiologist Blake Ushijima of the University of North Carolina, Wilmington, who was not involved in the research. He said the detective work by this team was 'really smart and significant.' Now that scientists know the cause, they have a better shot at intervening to help sea stars. Prentice said that scientists could potentially now test which of the remaining sea stars are still healthy — and consider whether to relocate them, or breed them in captivity to later transplant them to areas that have lost almost all their sunflower sea stars. Scientists may also test if some populations have natural immunity, and if treatments like probiotics may help boost immunity to the disease. Such recovery work is not only important for sea stars, but for entire Pacific ecosystems because healthy starfish gobble up excess sea urchins, researchers say. Sunflower sea stars 'look sort of innocent when you see them, but they eat almost everything that lives on the bottom of the ocean,' said Gehman. 'They're voracious eaters.' With many fewer sea stars, the sea urchins that they usually munch on exploded in population – and in turn gobbled up around 95% of the kelp forest s in Northern California within a decade. These kelp forests provide food and habitat for a wide variety of animals including fish, sea otters and seals. Researchers hope the new findings will allow them to restore sea star populations -- and regrow the kelp forests that Thurber compares to 'the rainforests of the ocean.' ___ The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute's Department of Science Education and the Robert Wood Johnson Foundation.

Major increase in colorectal cancer in younger adults tied to pandemic years, researchers say
New research on colorectal cancer rates in the U.S. has found that rates in younger adults increased 'steeply' before and during the early years of the Covid pandemic. There was a 50 percent relative increase between 2021 and 2022, according to the American Cancer Society. 'This trend contrasts with consistent increases of distant-stage diagnoses in this age group and likely reflects diagnosis of prevalent asymptomatic cancer through first-time screening due to recommendations for adults to begin screening at age 45 instead of age 50,' the authors said in a statement. The recommended age was lowered in 2021, in response to rising cases. Doctors hoped that doing so would encourage more screenings and help people to catch the cancer early. Screening is usually done as a colonoscopy through a primary care physician. Treatment is more successful earlier on than in later stages of the disease. 'Colorectal cancer is a devastating disease and the third leading cause of cancer deaths in the United States, yet about a quarter of adults ages 50 to 75 have never been screened for colorectal cancer. The Task Force reviews its recommendations about every five years to make sure they reflect the latest research,' Martha Kubik, registered nurse and U.S. Preventive Services Task Force member, told Healio then. 'By reducing the screening age, hopefully you capture more people as they're entering 50 than you ever did before,' Dr. Rachel Issaka, a gastroenterologist and assistant professor with UW Medicine, said then. Colorectal cancer deaths have surged since 2021. Last year, there were an estimated 152,810 new cases and 53,010 deaths. Whereas in 2023, there were an estimated 52,550 deaths, according to the Colorectal Cancer Alliance. This year, the American Cancer Society projects there will be more than 154,000 cases. Early onset cases have risen in the U.S. and around the world, and nearly double the number of young adults under the age of 55 years old are being diagnosed with colorectal cancer compared to a decade ago, according to the American Cancer Society. Since the mid-1990s, there has been a consistent annual increase of two percent in cases among American adults between the ages of 20 and 39, the Cancer Research Institute reports. Doctors have multiple theories for what's happening, with recent studies linking increased U.S. cases to poor nutritional health and a toxin in the gut. But, researchers still have not found a concrete answer and upward trends are projected to continue. By 2030, Issaka says colorectal cancer is predicted to be the leading cause of cancer death for people under 50. 'We really need to have people understand that colorectal cancer isn't an old people's disease anymore,' she said. The new research was published on Monday in the journal JAMA Network. The study was released alongside two others that looked at trends in screening and screening strategies. The other research saw screening rates also increasing among the same age group, which was consistent with a previous report. But, a March survey commissioned by the Colorectal Cancer Alliance found more than half of adults prioritize household chores over getting a possibly life-saving colorectal cancer screening. 'These results reveal a life-threatening gap in public awareness of colorectal cancer,' Dr. Christopher Lieu, a medical oncologist and advisor to the Colorectal Cancer Alliance, said in a statement.
