| Posted: 30 Aug 2021 07:49 AM PDT Half of pregnant women who had a simple blood test to check their iron stores had low iron levels, and one in four had severe iron deficiency, according to a new article. But despite how common iron deficiency is, 40% of pregnant women in this large regional study never had their iron levels checked, and women of lower socioeconomic status were less likely to get tested. Researchers said the findings underscore the need to revisit clinical guidelines to ensure that ferritin testing, the standard measure of iron deficiency, is included as a routine part of maternal care and pregnancy health screenings. |
| Unease beyond the uncanny valley: How people react to the same faces Posted: 30 Aug 2021 07:49 AM PDT If humanoid robots with the same appearance are mass-produced and become commonplace, how will human beings react to them? In a series of six experiments, scientists examined peoples' reactions when presented with images of people with the same face. Their results reveal a new phenomenon they call the clone devaluation effect -- a greater eeriness associated with cloned faces than with different faces. |
| Finerenone improves outcomes in patients with mild-to-moderate kidney disease and diabetes Posted: 30 Aug 2021 07:00 AM PDT Finerenone reduces the risk of cardiovascular morbidity and mortality in patients with mild-to-moderate kidney disease and type 2 diabetes. Diabetic kidney disease develops in approximately 40% of patients with diabetes and is the leading cause of chronic kidney disease worldwide. Some patients progress to end-stage renal disease, but most die from cardiovascular diseases and infections before needing kidney replacement therapy. |
| New study examines ‘Achilles heel’ of cancer tumors, paving the way for new treatment strategies Posted: 30 Aug 2021 07:00 AM PDT Researchers have uncovered a weakness in a key enzyme that solid tumor cancer cells rely on to adapt and survive when oxygen levels are low. |
| Increased survival with eye melanoma in clinical trial Posted: 30 Aug 2021 07:00 AM PDT Once it has spread (metastasized), uveal (intraocular or eye) melanoma -- an unusual form of cancer -- has a very high mortality rate. Researchers and doctors show that, in a small group of patients with metastatic uveal melanoma, a new combination treatment can bring about tumor shrinkage and prolonged survival. |
| How can I avoid heart disease or stroke? Posted: 30 Aug 2021 06:59 AM PDT As much as 90% of the risk of a heart attack, stroke, or peripheral arterial disease (PAD) can be explained by smoking, poor eating habits, lack of physical activity, abdominal obesity, high blood pressure, raised blood lipid levels, diabetes, psychosocial factors, or alcohol. These guidelines focus on atherosclerotic cardiovascular disease (CVD), which affects the arteries. As the inside of the arteries become clogged up by fatty deposits, they can no longer supply enough blood to the body. This process is the main cause of heart attacks, strokes, PAD and sudden death where arteries become completely blocked. The most important way to prevent these conditions is to adopt a healthy lifestyle throughout life, especially not smoking, and to treat risk factors. |
| Turning cameras off during virtual meetings can reduce fatigue Posted: 30 Aug 2021 06:22 AM PDT Feeling drained after a day of virtual meetings is worse for those who keep their cameras on throughout those meetings, according to new research.

| Perceptions of supernatural beings reveal feelings about good and bad in humans Posted: 30 Aug 2021 05:18 AM PDT What transpires in comedies and cartoons when a character has a devil on one shoulder and an angel on the other is not far off from people's perceptions of the real world, finds a new study. |
| Eating walnuts daily lowered 'bad' cholesterol and may reduce cardiovascular disease risk Posted: 30 Aug 2021 05:18 AM PDT Healthy older adults who ate a handful of walnuts (about ½ cup) a day for two years modestly lowered their level of low-density lipoprotein or LDL cholesterol levels. Consuming walnuts daily also reduced the number of LDL particles, a predictor of cardiovascular disease risk. The study explored the effects of a walnut-enriched diet on overall cholesterol in elderly individuals from diverse geographical locations and spanning two years. |
| COVID-19 antibody study shows downside of not receiving second shot Posted: 30 Aug 2021 05:18 AM PDT A new study shows that two months after the second Pfizer/Moderna vaccination, antibody response decreases 20 percent in adults with prior cases of COVID-19, and tests how well current vaccines resist emerging variants. The study also showed that prior exposure to SARS-CoV-2 does not guarantee a high level of antibodies, nor does it guarantee a robust antibody response to the first vaccine dose. This directly contradicts the assumption that contracting COVID will naturally make someone immune to re-infection. The findings further support vaccination (and two doses), even for people who have contracted the virus previously. |
| Staying home, having access to primary care, and limiting contagion hubs may curb COVID-19 deaths Posted: 30 Aug 2021 05:18 AM PDT Staying home and limiting local travel, supporting access to primary care, and limiting contacts in contagion hubs -- including hospitals, schools, and workplaces -- are strategies that might help reduce COVID-19-related deaths, according to new research that analyzed the first wave of the epidemic in Italy. |
| Light-to-moderate coffee drinking associated with health benefits Posted: 30 Aug 2021 04:56 AM PDT Up to three cups of coffee per day is associated with a lower risk of stroke and fatal heart disease, according to new research. |
| Posted: 29 Aug 2021 05:19 AM PDT The first large-scale, long-term trial of a new strategy using combinations of very low-doses in one capsule, has demonstrated significantly improved control of high blood pressure -- the leading cause of heart attack and stroke. |
| Brain tissue inflammation is key to Alzheimer's disease progression Posted: 26 Aug 2021 08:17 AM PDT Neuroinflammation is the key driver of the spread of pathologically misfolded proteins in the brain and causes cognitive impairment in patients with Alzheimer's disease, researchers reveal in a new article. |
