The process of biopsy is important for confirming the presence of cancer. In the conventional histopathology technique, tissue is excised, sliced, stained, mounted on slides, and examined under a microscope to identify cancerous markers. This lengthy procedure often results in patients waiting weeks or months for their results, causing treatment delays and heightened anxiety. Now, a breakthrough digital medical imaging system promises to transform cancer detection by offering instantaneous results, facilitating timely and effective treatment across all cancer types. The Photon Absorption Remote Sensing (PARS) system, an innovative, built-from-scratch technology developed by researchers at the University of Waterloo (Ontario, Canada), marks a radical departure from traditional cancer detection methods, promising diagnoses within minutes and enabling rapid surgical intervention. The system utilizes lasers to irradiate tissue samples, producing a comprehensive, high-resolution data set. This data is then processed by an artificial intelligence (AI) system that converts it into a conventional histopathology ...
Alzheimer’s disease (AD) is a neurodegenerative condition that causes the brain to deteriorate over time, marked by the buildup of certain harmful proteins that eventually lead to a decline in brain function and cell death. These changes can happen long before any symptoms show up. Scientists have found certain proteins in the cerebrospinal fluid that are good indicators of AD. One of the most promising markers for early and more precise detection of AD in the blood is phosphorylated tau at position 217 (pTau217). It’s seen as a game-changer for diagnosing AD sooner, categorizing patients for research studies, and improving how patients are cared for and treated. Now, an innovative and novel blood test can be used in the screening, diagnosis, and monitoring of AD based on the circulating level of this promising biomarker pTau217. ALZpath Dx (Carlsbad, CA, USA) has developed a robust and scalable plasma-based ultra-sensitive assay, branded ...
Our teenaged son never misses an opportunity to tease me when I do something he deems old-fashioned. “Hey Mom and Dad,” he’ll ask, “what was it like back in the 1900’s?” While our son’s question is rhetorical, it did get us thinking about how much has changed in our field of study: medicine. At the start of the 1900s, the practice of medicine was based on a “symptom model” where care was sought when patients felt poorly and would see a doctor who would try to make them feel better. Addressing symptoms is important, but in the 21st century, many major medical problems do not present symptoms before they cause trouble. No one has ever said, “I feel I may have a stroke soon,” or “I think I may break a hip.” So, what about age itself? Is aging symptomatic? Is aging a disease? Can aging be fixed? In cardiology, ...

Dr. Heather Sandison, a leading expert in Alzheimer’s Disease and Related Dementia (ADRD) care, has recently published a groundbreaking study in the Journal of Alzheimer’s Disease, highlighting significant improvements in cognitive function among individuals with cognitive decline. The study is the second to employ a multimodal, individualized care plan and offers further hope for managing and potentially reversing cognitive impairment. The study, “Improved Cognition in People with Cognitive Decline: A Multimodal Intervention Approach,” is published in the Journal of Alzheimer’s Disease Volume (94) Issue (3) and focused on individuals with objective cognitive impairment (OCI), a precursor to Alzheimer’s disease. Dr. Sandison and her team recruited 34 participants from the San Diego, CA area to receive a comprehensive intervention based on potential contributors to cognitive decline, such as lifestyle changes, nutraceutical support, and medications. Over the course of six months, the participants underwent regular clinical visits and received ongoing nutrition support ...
Pfizer on Wednesday said its experimental vaccine targeting the potentially deadly bacterial disease Group B Streptococcus returned strong mid-stage clinical trial results, a promising step as the drug inches toward potential approval. Pfizer is among several drugmakers racing to develop the world’s first shot targeting Group B strep disease, which is linked to nearly 150,000 infant deaths worldwide each year, especially in lower-income countries. The Food and Drug Administration in September granted breakthrough therapy designation to Pfizer’s vaccine, which is intended to expedite the development and review of the shot. Pfizer’s single-dose shot generated antibodies that may provide infants with meaningful protection against the disease, according to the data released Wednesday from a phase two clinical trial. The jab is administered to expectant mothers, who pass vaccine-induced antibodies to their fetuses. One of the company’s vaccines targeting respiratory syncytial virus also uses that maternal vaccination method. ...
Cambridge scientists have identified a signature in the blood that could help predict how well an individual will respond to vaccines. The discovery, published today in Nature Communications, may explain why, even among vulnerable patient groups, some individuals have better responses to vaccines than others. During the COVID-19 pandemic, it has become clear that some patients are better protected by vaccination than others. Many studies have shown that SARS-CoV-2 vaccines are less effective in people with weakened immune systems, but also that this effect is not uniform. Vaccination involves priming the immune system to look for—and get rid of—invading pathogens, such as viruses and bacteria. In part, this involves stimulating the production of antibodies uniquely programmed to identify a particular invader. These antibodies are themselves produced by a type of immune cell known as a B cell. One specific subset of B cells is known as age-associated B cells (ABCs). ...
Researchers led by Christi Gendron at the University of Michigan, US, have found the link between death perception and reduced aging in flies. Their new study, published June 13th in the open access journal PLOS Biology shows that a specific group of brain cells in the fly, called R2 and R4 neurons, are activated when flies encounter other dead flies, and that this increased activity leads to more rapid aging. Aging is a complex process that can be affected by both genetics and the environment. While we know that perceptual experiences can affect aging, how this happens is still mostly a mystery. One example is the effect of “death perception” in fruit flies. Previously, the group at the University of Michigan reported that when fruit flies see other dead fruit flies, they experience advanced aging, and that this depends on a type of serotonin receptor. In their new follow-up study, ...
Just two months after Emergent BioSolutions made history by winning the FDA’s blessing to sell its opioid reversal medicine over the counter, a new treatment option has arrived in Indivior’s Opvee. The nod, which covers Opvee’s use in people 12 years of age and older, marks the first approval for the medicine’s active ingredient in nasal spray form. The molecule, nalmefene hydrochloride, was first approved in the 1990s in an injectable format but was later pulled from the market in 2008. This time around, the FDA endorsed the drug based on new evidence that it can help combat rising overdose rates in the U.S. Indivior, which closed its purchase of Opiant in March and picked up the medicine in that buyout, plans to launch Opvee in the fourth quarter of 2023. The FDA’s approval comes as overdoses attributable to synthetic opioids such as fentanyl are on the rise, with more ...
