Pregnant women in Japan who responded to an online survey early in the COVID-19 pandemic demonstrated higher levels of anxiety compared to women undergoing fertility treatments and to pregnant women in Iran. The findings were published in the Journal of Affective Disorders Reports. "The pandemic has changed the social environments of pregnant women and fertility patients," says Tohoku University clinical psychologist Koubon Wakashima. For example, restrictions in Japan meant that pregnant women have been unable to participate in group parenting classes or travel to their parents' homes to receive traditional childbirth assistance. Medical institutions in the country reported fewer women accessing infertility ...

WASHINGTON--Biological differences between females and males affect virtually every aspect of medicine and biomedical research. In a new Scientific Statement released today, the Endocrine Society called for sex differences to be studied thoroughly to improve public health. "When we understand the ways sex differences operate at baseline in health, which can either worsen the course of a disease to amplify differences in health outcomes, or protect against it, we can more effectively prevent and treat medical conditions," said Aditi Bhargava, Ph.D., of the University of California, San Francisco in San Francisco, Calif., and the chair of the writing group that authored the Society's Scientific Statement. For instance, SARS CoV-2 infection, cause of the COVID-19 pandemic, disproportionately ...

WINSTON-SALEM, N.C. - March 11, 2021- For people who are overweight or obese and have type 2 diabetes, the first line of treatment is usually lifestyle intervention, including weight loss and increased physical activity. While this approach has cardiovascular benefit for many, it can be detrimental for people who have poor blood sugar control, according to a study conducted by researchers at Wake Forest School of Medicine. In the study, published in the current issue of the journal Diabetes Care, the researchers re-evaluated the National Institutes of Health Action ...

Several years after scientists discovered what was considered the oldest crater a meteorite made on the planet, another team found it's actually the result of normal geological processes. During fieldwork at the Archean Maniitsoq structure in Greenland, an international team of scientists led by the University of Waterloo's Chris Yakymchuk found the features of this region are inconsistent with an impact crater. In 2012, a different team identified it as the remnant of a three-billion-year-old meteorite crater. "Zircon crystals in the rock are like little ...

WASHINGTON -- As growing vaccine demand signals a potential turning point in the global COVID-19 pandemic, the nation's health crisis is far from over. One year after the World Health Organization declared COVID-19 a global pandemic, many adults report undesired changes to their weight, increased drinking and other negative behavior changes that may be related to an inability to cope with prolonged stress, according to the American Psychological Association's latest Stress in America™ poll. APA's survey of U.S. adults, conducted in late February 2021 by The Harris Poll, shows that a majority of adults (61%) experienced undesired weight changes - weight gain ...

The U.S. Congress and Biden-Harris administration have a clear opportunity to supercharge global health research and development (R&D) in the wake of a pandemic that has revealed both the sector's chronic neglect and amazing potential, according to a detailed agency-by-agency action plan released today by the nonprofit Global Health Technologies Coalition (GHTC). "The same core capabilities instrumental to defeating COVID-19 can also defeat diseases that have plagued humanity for generations--such as AIDS, tuberculosis, malaria and Ebola--while targeting emerging pathogens of pandemic potential," said GHTC Director Jamie Bay Nishi. "Developing vaccines in ...

Reforestation could help to combat climate change, but whether and where to plant trees is a complex choice with many conflicting factors. To combat this problem, researchers reporting in the journal One Earth on December 18 have created the Reforestation Hub, an interactive map of reforestation opportunity in the United States. The tool will help foresters, legislators, and natural resource agency staff weigh the options while developing strategies to restore lost forests. "Often the information we need to make informed decisions about where to deploy reforestation already exists, it's just scattered across a lot of different locations," says author Susan Cook-Patton, a Senior Forest Restoration Scientist at the Nature Conservancy. "Not everybody has the ...

The impact of the COVID-19 pandemic on public health is staggering; more than one hundred million cases and two million deaths worldwide. In response, most countries and local governments have taken substantial measures -- such as travel restrictions and physical distancing -- to keep their citizens safe. Both the pandemic and related protective measures pose challenges for ongoing clinical research studies seeking to treat and prevent the world's greatest public health emergencies including COVID-19, but also Alzheimer's disease and other dementia. In a new paper from the World-Wide FINGERS network in Alzheimer's ...

Nurses also advocate for patients and their caregivers to ensure they receive appropriate information and education to successfully navigate phases of treatment in the hospital and after discharge. A series of three new Scientific Statements, "Care of the Patient With Acute Ischemic Stroke," from the American Heart Association, published today in Stroke, a journal of the American Stroke Association, a division of the American Heart Association, provide the latest evidence-based guidance ...

Results published today show it is possible to identify Parkinson's based on compounds found on the surface of skin. The findings offer hope that a pioneering new test could be developed to diagnose the degenerative condition through a simple and painless skin swab. Scientists at The University of Manchester have developed a technique which works by analysing compounds found in sebum - the oily substance that coats and protects the skin - and identifying changes in people with Parkinson's Disease. Sebum is rich in lipid-like molecules and is one of the lesser studied biological fluids in the diagnosis of the ...

An interdisciplinary research team at Lehigh University has unraveled how functional biomaterials rely upon an interfacial protein layer to transmit signals to living cells concerning their adhesion, proliferation and overall development. According to an article published today in Scientific Reports, the nanoscale features and properties of an underlying substrate do not impact the biological response of cells directly. However, these properties indirectly influence cell behavior through their control over adsorbed proteins. In the article, "Nanostructure ...

Firefly beetles rank among the world's most charismatic creatures, with luminous courtship displays that have now turned them into a popular attraction for wildlife tourists. In the first comprehensive review of firefly tourism, published in the journal Conservation Science and Practice, an international team of biologists led by a Tufts University researcher, reveal that an estimated 1 million people now travel each year to witness bioluminescent performances starring some two dozen firefly species around the world. But the authors also point out that while this unique, insect-based tourism ...

An eight-week programme of mindfulness meditation improves quality of life and reduces fear of activity in heart attack patients, according to research presented today at ESC Acute CardioVascular Care 2021, an online scientific congress of the European Society of Cardiology (ESC).1 "A heart attack is a serious life-threatening event and survivors can suffer from low quality of life," said study author Dr. Canan Karadas of Hacettepe University, Ankara, Turkey. "One reason is a fear of movement, called kinesiophobia, which limits daily activity due to concerns of another heart attack." "Mindfulness refers to the mental state achieved by focusing awareness on the present moment, ...

The research was published on the journal Nature Catalysis on December 14, 2020. A strong bias towards linear and disc-shaped molecules has long been observed in drug molecules. In contrast, spherical molecules have been utilized on far fewer occasions, due to the lack of efficient access to the latter chemical space. Specifically, efficient strategies to synthesize tetraarylmethanes, a unique family of spherical molecules, have remained scarce. Chiral tetraarylmethanes (CTAMs), a unique family of spherical molecules which bear four different aryl groups with defined stereochemistry, remain as a mystery due to the lack of efficient asymmetric synthesis. The challenge in asymmetric synthesis of CTAMs lies in not only the high barrier in making ...

Giving at scale by the super-wealthy has done little to redistribute wealth from rich to poor, helping perpetuate social inequalities rather than remedying them, while paying considerable dividends to donors in the form of privilege and influence in society and politics, new research shows. In the research paper 'Elite philanthropy in the United States and the United Kingdom in the new age of inequalities' researchers at the University of Bath School of Management and Newcastle University Business School also conclude that giving by the super-wealthy has failed significantly to benefit poor countries in the developing ...
