Local experts react to FDA approval of blood test biomarker for early Alzheimer's detection
Earlier this month, the FDA approved another biomarker to help millions of patients and families affected by Alzheimer's disease: a blood test that detects amyloid plaques, a hallmark of the disease.
Channel 11 spoke with those fighting for a cure here in the Pittsburgh area. Sara Murphy, vice president for programs and services for the Greater Pennsylvania chapter of the Alzheimer's Association, said while there's still work to be done, this FDA clearance is a huge step for early detection.
'Hearing the news, it really marked another milestone,' Murphy said. 'Early detection is really, really important for peace of mind, but also, so they can access and be eligible for some of these newly approved treatments.'
More than 7 million Americans are living with Alzheimer's disease, according to the Alzheimer's Association, and experts believe those numbers could skyrocket to around 12.7 million by the year 2050. They believe this test, which comes in the form of a blood draw, could be a game changer for millions, as the test is less invasive than other methods, including PET scan imaging or a spinal tap.
'This will detect the earliest signs of amyloid plaques in the blood for adult patients age 55-plus that are exhibiting signs and symptoms of the disease,' Murphy said.
The Alzheimer's Association said while there is still no stand-alone test for diagnosing the disease, blood tests are more common than other methods and easily accessible in a specialized setting, so it's important to talk to your doctor about what treatment options are available.
'Once that person has had a conversation with their provider about some of the warning signs and symptoms, that is now another choice in the toolbox to be able to be aware that they can have this,' Murphy said.
More discussion about blood biomarker tests will likely take place this summer at the Alzheimer's Association International Conference in July.

Meet Your Trusted Dental Implant Specialist in Lake Mary
Are you missing one or more teeth and looking for a permanent, natural-looking solution? Dental implants may be the answer you've been searching for. But choosing the right professional makes all the difference. In this article, we'll walk you through everything you need to know about dental implants, what to expect, and—most importantly—how to meet your trusted dental implant specialist in Lake Mary who can restore your smile with confidence and precision. Dental implants are titanium posts that act as artificial tooth roots. Surgically placed into the jawbone, they fuse with the bone through a process called osseointegration, creating a stable foundation for replacement teeth such as crowns, bridges, or dentures. Compared to traditional tooth replacement methods like removable dentures or bridges, dental implants are more durable, comfortable, and functional. They prevent bone loss, maintain facial structure, and help you eat, speak, and smile naturally. According to the American Academy of Implant Dentistry , over 3 million Americans have dental implants, and that number is growing by 500,000 each year. As more patients discover the life-changing benefits of implants, the demand for skilled implant specialists continues to rise. You might benefit from dental implants if you have: One or more missing teeth Difficulty chewing or speaking due to tooth loss Jawbone deterioration from prolonged tooth absence An ill-fitting denture or bridge A desire for a permanent and aesthetically pleasing solution A comprehensive evaluation with a qualified specialist will determine if you're a candidate. This includes digital imaging, a review of your oral and medical history, and possibly bone grafting if you have low bone density. Understanding the procedure helps reduce anxiety and sets realistic expectations. Here's how it works: Your journey starts with a detailed consultation. The implant specialist will assess your oral health, bone density, and suitability for implants. A customized treatment plan is then developed. Under local anesthesia or sedation, the specialist surgically places the implant post into the jawbone. Healing typically takes 3–6 months, allowing the implant to fuse with the bone. Once healed, an abutment (connector) is attached to the implant. This part will hold your final crown, bridge, or denture. A custom-made crown or prosthesis is then attached to the abutment. Your new tooth will match your natural teeth in color, shape, and function. While many general dentists offer implants, a trusted dental implant specialist brings advanced training, experience, and technology to ensure better outcomes. Here's what sets them apart: Specialized Training: Periodontists and oral surgeons undergo additional years of education focused on implantology and oral surgery. Periodontists and oral surgeons undergo additional years of education focused on implantology and oral surgery. Precision Technology: Advanced tools like 3D imaging and guided surgery systems improve accuracy and reduce risk. Advanced tools like 3D imaging and guided surgery systems improve accuracy and reduce risk. High Success Rates: Specialists have higher implant success rates and are more adept at managing complex cases. When you choose to meet your trusted dental implant specialist, you're investing in the long-term success of your oral health and smile. Lake Mary is home to several dental professionals, but not all have the same level of expertise. Here's how to find the right fit: Look for board certifications, years of practice in implant dentistry, and memberships in professional organizations like the American Academy of Implant Dentistry (AAID) or the International Congress of Oral Implantologists (ICOI). A reputable specialist uses state-of-the-art technology such as CBCT scans, intraoral scanners, and digital treatment planning. Satisfied patients are a strong indicator of quality care. Check reviews and ask to see real results. Choose a clinic that offers everything from consultations to restoration under one roof for a seamless experience. If you're located in Central Florida, seeking dental implants Lake Mary ensures accessibility and continuity of care. Local specialists understand the needs of the community and are available for follow-ups, adjustments, or urgent issues without the hassle of long-distance travel. Choosing a Lake Mary-based specialist also supports your local economy and builds a lasting relationship with a provider who understands your dental history. One of the most common concerns is cost. Dental implants can range from $3,000 to $5,000 per tooth, depending on the complexity and materials used. However, many practices in Lake Mary offer: Flexible payment plans In-house membership discounts Financing through companies like CareCredit Insurance coordination, where applicable Always ask for a transparent cost breakdown and what's included (e.g., consultation, surgery, crown, imaging). Post-surgery care is crucial for healing and long-term success. Follow these tips: Stick to soft foods for a few days post-op Practice excellent oral hygiene, including gentle brushing and flossing Attend regular dental checkups and cleanings Avoid smoking or chewing hard objects Use any prescribed medications as directed Dental implants can last a lifetime with proper care, making them a worthwhile investment. Missing teeth can affect your appearance, confidence, and overall health. But you don't have to live with discomfort or insecurity. With the right guidance and expertise, you can reclaim your smile and quality of life. When you're ready to take the next step, meet your trusted dental implant specialist in Lake Mary. Their expertise, compassionate care, and cutting-edge approach will ensure that your journey toward a restored smile is smooth and successful. Ready to transform your smile with dental implants?

FDA: More cucumbers, ready-to-eat products recalled in growing salmonella outbreak
A Maryland food company has recalled specific salsa and cucumber products because they were made with cucumbers that are possibly contaminated with salmonella. TGD Cuts, LLC of Jessup, Maryland, is recalling some tub and tray products because they contained cucumbers from Boynton Beach, Florida-based Bedner Growers Inc., which have been linked to a salmonella outbreak. TGD Cuts distributed the affected products, which included salsas, sliced cucumbers and cucumber spears, to retail and foodservice locations in Maryland, Virginia, Pennsylvania, New Jersey, and North Carolina, according to the Food and Drug Administration (FDA). The products had use-by dates ranging from May 20 to May 28 and are unlikely to be in stores or being used. No illnesses have been reported in connection with the products, the FDA said. Egg recall: Brown eggs sold at some Walmart stores have salmonella risk The initial May 19 recall involved cucumbers sold directly to consumers at Bednar's Farm Fresh Market, according to notices published May 19 by the Centers for Disease Control and Prevention (CDC) and the FDA. Subsequent recalls have been announced by grocers such as Harris Teeter, Kroger and Walmart for repackaged cucumbers for resale under different brand names or those used in ready-to-eat products, including vegetable trays and salads. The cucumbers, distributed by Fresh Start Produce Sales of Delray, Florida, also led to Target recalling individual cucumbers on May 30, specifically cucumber two-packs and various prepared foods products. In addition to the growing cucumber-related recall, other products have been recalled recently for potential salmonella contamination. The FDA on May 28 upgraded a recall of tomatoes distributed in three southern states to a Class I recall, meaning consumption of the food could cause serious health complications or lead to death. Then, on June 6, the CDC and FDA linked brown eggs sold in nine states – including at some Walmart stores – to an ongoing Salmonella Enteritidis outbreak, in which 79 people have been sickened and at least 21 hospitalized. Customers who purchased any products from TGD Cuts should get rid of them or return them for a full refund. Here is the list of products recalled due to a possible salmonella risk. Salmonella poisoning causes about 1.35 million illnesses, 26,500 hospitalizations, and 420 deaths each year in the U.S., according to the CDC and FDA. Symptoms, which include diarrhea, fever and stomach cramps, will usually occur six hours to six days after exposure and may last up to seven days. Symptoms from severe infections may include aches, headaches, elevated fever, lethargy, rashes, and blood in urine or stool. Mike Snider is a reporter on USA TODAY's Trending team.

Letters: He overdosed after being turned away by S.F. drug treatment center. Mother seeks answers
Jonathan Martin, my son, overdosed after he was turned away from HealthRight360's detox facility on Aug. 27, 2024. Jonathan was desperately ill and seeking help. He died alone early the next morning. Jonathan's death was the subject of a Chronicle story ('He overdosed waiting for help. Why did S.F.'s largest drug treatment center provider turn him away?' San Francisco, Feb. 27). When the story was published, I sent a letter to Mayor Daniel Lurie, District Attorney Brooke Jenkins, the chiefs of the Department of Public Health and relevant agencies, HealthRight360 CEO Vitka Eisen and every member of the Board of Supervisors, hoping to find out why my son was turned away. I wanted to understand what prevented him from receiving the services he so urgently needed. I have still not received a single response, explanation or even a note of condolence from any of these officials. If the people who oversee drug treatment in the city will not answer a grieving mother, who will give my family answers? Citizens of San Francisco: You voted these people into office. Is this how you want your loved one to be treated while trying to seek help? The silence from those in power is deafening. Our family demands answers. Carolyn Stueve-Martin, Tulsa, Okla. Don't hide Pride I empathize with her desire for concealment, misdirection or camouflage during a time of danger. My wife is trans, and this is a scary time for us. But I am afraid that Judd is missing the purpose of Pride entirely. Pride is not about shame. It's not about showing off our most socially acceptable community members in the hopes that bigots will leave the rest alone. It is the bigots who should be ashamed. A Pride celebration that is ashamed of its trans and genderqueer members — who are, as Judd wrote, just people trying to live their lives openly and freely — is no Pride at all. Amanda Seyfer, Oakland Big Brother rising Technology has always been a double-edged sword. Fire can provide warmth and light, but it can also be used to burn down an enemy village. IBM's punch cards helped make Social Security possible, but also enabled Hitler's destruction of European Jewry. Today, a shadowy Bay Area company called Palantir is coalescing federal government information on Americans into a database that would allow it to target anyone who dissents from its autocratic policies or has characteristics that it does not favor. We need our representatives (or the courts) to block this monstrous machine before it rolls over us and makes this country a new Reich just like the old Reich.
