THURSDAY, Nov. 10, 2022 (HealthDay News) -- When it comes to pollen allergies, there are not only bad days and bad seasons, experts with the right technology can now break down pollen counts by the hour.Specifically, pollen counts are lower between 4 a.m. and noon, a new study done in Georgia found. They’re higher between 2 p.m. and 9 p.m.While experts have been monitoring pollen levels for many years to better understand them and advise patients, they typically measure counts for a 24-hour period, said lead author Dr. Stanley Fineman, an allergist with Atlanta Allergy and Asthma.For the new study, his team and researchers at Emory University in Atlanta used imaging technology to measure pollen in real time.The investigators found that higher counts seemed to align with rising...

THURSDAY, Nov. 10, 2022 (HealthDay News) -- Gene editing has for the first time produced modified immune cells finely honed to target and attack cancer cells, researchers say.A team used the gene editing tool CRISPR to alter immune cells drawn from 16 patients who had a variety of solid cancers, including colon, breast and lung.According to a report in the journal Nature, the genes of these immune cells were edited to add 175 newly isolated cancer-specific immune receptors. That would allow the cells to recognize and target mutations in the patients’ own cancer cells, researchers said."This is a leap forward in developing a personalized treatment for cancer, where the isolation of immune receptors that specifically recognize mutations in the patient's own cancer are used to treat the...

THURSDAY, Nov. 10, 2022 (American Heart Association News) -- A popular type of fertility treatment is associated with increased risk for serious cardiovascular complications in women at the time of delivery, longer hospital stays and higher hospitalization costs, new research finds."It's not necessarily that reproductive technologies are causing the cardiac complications," said Dr. Erin Michos, senior author of the study, which was presented Monday at the American Heart Association's Scientific Sessions conference and published in the American Journal of Cardiology."It may be that women with infertility are at greater risk for cardiovascular complications due to age and other health problems, and they just need a little bit closer attention during pregnancy, delivery and postpartum,"...

THURSDAY, Nov. 10, 2022 (HealthDay News) -- A new study harnesses the power of mindfulness to help overanxious people calm themselves -- and the benefit may equal the use of an antidepressant, according to researchers at Georgetown University Medical Center in Washington, D.C.Olga Cannistraro said practicing mindfulness certainly helped her. "There was something excessive about the way I responded to my environment," she explained.Cannistraro, now 52, decided to join a study on mindfulness-based stress reduction (MBSR) for anxiety disorders 10 years ago. The study was led by Dr. Elizabeth Hoge, who directs the Anxiety Disorders Research Program at Georgetown. MBSR "gave me the tools to spy on myself," Cannistraro explained in a center news release. "Once you have awareness of an...
