Research has found that training stroke survivors to walk at a faster speed during recovery can help improve the brain function that enables people to walk and perform another task simultaneously, known as dual-task walking. The research, led by academics at Oxford Brookes University, was funded by the Stroke Association. People who've had a stroke often struggle to walk and do tasks that involve thinking at the same time, for example, activities such as walking and holding a conversation, or planning what to do next. To effectively walk in the community, cognitive effort is needed to navigate safely and deal with distractions. Many people fail to regain this ability after a stroke. Dual-task ...

Vitamin B12 is essential for proper functioning of the nervous system and blood cells and also plays an important role in DNA synthesis in all our cells. Vitamin B12 deficiency causes fatigue, muscle weakness, headaches, and sometimes even serious neurological symptoms. Usually, the necessary amounts of B12 are absorbed from food in our digestive tract; however, in 0.1-2% of individuals, the epithelial lining of the stomach fails to produce a glycoprotein intrinsic factor that is needed for proper absorption of B12. This leads to vitamin B12 deficiency and a certain type of anemia called pernicious anemia. Pernicious ...

The research team used data from world renowned health study Children of the 90s, to answer three research questions: Is school enjoyment patterned by biological sex at birth, socioeconomic background of cognition? How does school enjoyment relate to GCSE achievement? Does school enjoyment relate to social or sex differences in GCSE achievement? The team found that pupil's school enjoyment measured at six years old is patterned by their sex and cognitive ability but not their family's socioeconomic background. For example, girls were twice as likely to report enjoying school than boys. School enjoyment strongly related to GCSE achievement at age 16 even after consideration of their socioeconomic background ...

UNIVERSITY PARK, Pa. -- Workers in the service industry are often pressured by their employers to give friendly "service with a smile." New research suggests that when those employees also rely on tips to earn a living, it creates a power dynamic between the employee and customer that may increase the likelihood of sexual harassment on the job. Alicia Grandey, liberal arts professor of psychology at Penn State, said the findings could give insight into how companies can help reduce sexual harassment from customers, including raising employees' hourly wages. "It may not be necessary to completely eliminate customer tips, but rather reduce the dependence on tips by offering a livable wage," Grandey said. "Based on our results, if employees were ...

WASHINGTON (June 21, 2021)--Previous research has suggested that the stress of discrimination may play a role in the development of health problems that disproportionately affect lesbian, gay and bisexual individuals. A study published today finds that when lesbian, gay and bisexual adults are exposed to even mild anti-gay prejudice, it triggers bodily changes such as increases in blood pressure that can contribute to heart disease. "This study provides strong evidence that when LGB people experience anti-gay prejudice, their bodies respond with increases in heart rate and blood pressure, and in the stress hormone cortisol," David M. Huebner, a professor of prevention and community health at the George Washington University and lead author of the study, said. "When the body responds ...

Lesbian, gay and bisexual people who encounter homophobic attitudes experience increases in heart rate, blood pressure and stress hormones, potentially putting them at risk for multiple health problems, according to research published by the American Psychological Association. "This study shows the potentially toxic impact discriminatory attitudes can have on lesbian, gay and bisexual people's health," said lead author David M. Huebner, PhD, associate professor of prevention and community health at The George Washington University. "This is just one more, among many, corrosive effects of homophobia." In the study, published in the journal Health Psychology, researchers looked at 134 lesbian, gay and bisexual ...

Relationships are often undermined by everyday frustrations like work stress or financial anxiety, but how do couples handle a challenge as unprecedented as the COVID-19 pandemic? People who blamed their stress on the pandemic more than on their partner were happier in their relationship, a new study in Social Psychological and Personality Science reports. Previous research has shown that romantic partners tend to be more critical toward each other when experiencing common stress, but major events like natural disasters are not always associated with poor relationship functioning. Because these significant stressors ...

Durham, NC - A team led by researchers at Newcastle University, UK has successfully created a model of the cells found in the lungs that can be used to replicate how COVID-19 infects the airways. This information, reported today in the STEM CELLS journal, paves the way for broader studies of viral lung infections using a cost-effective system that can easily be manufactured on a large scale. COVID-19, which to date has resulted in more than 3.5 million deaths worldwide, has brought on an urgent need for airway models that can be used to develop effective therapies. While the use of in vitro (outside the body) models generated from primary pulmonary epithelial cells that mimic the human ...

In a retrospective study believed to be one of the largest of its kind, researchers say they have successfully charted the health risks, growth patterns, and medical and surgical outcomes of 1,374 people with the most common form of dwarfism, called achondroplasia, seen over a 60-year period at four academic medical centers, including Johns Hopkins Medicine. The findings, according to the researchers, not only affirm some long-standing views and trends in the care of those with the condition, but also offer a standardized baseline, a blueprint investigators hope will serve to speed diagnosis and improve patients' quality of life and health. Achondroplasia is caused by a rare genetic mutation that alters the activity of the fibroblast growth factor receptor 3 (FGFR3) gene involved in bone ...

The most severe mass extinction event in the past 540 million years eliminated more than 90 percent of Earth's marine species and 75 percent of terrestrial species. Although scientists had previously hypothesized that the end-Permian mass extinction, which took place 251 million years ago, was triggered by voluminous volcanic eruptions in a region of what is now Siberia, they were not able to explain the mechanism by which the eruptions resulted in the extinction of so many different species, both in the oceans and on land. Associate professor Laura Wasylenki of Northern Arizona ...

A method for making ultrathin sensors for monitoring the health of crops could help farmers grow more food without putting extra demands on the land. Intensive agriculture is already contributing to widespread biodiversity loss and climate change, yet growing populations continue to put pressure on farmers to produce more food. The challenge now lies in increasing agricultural output without clearing more land or applying excessive fertilizers. Precision farming is a promising solution that involves real-time monitoring of plant needs and responding to them with just the right amount of water, light or nutrients. "Precision farming typically relies on soil-based sensors or drones fitted with special cameras," says Ph.D. student Abdullah ...

A SARS-CoV-2 lateral flow test that combines two bacterial enzymes with genetic sequences and a couple of probes is cheaper and easier to use than PCR tests while producing comparably reliable results. Called Vigilant and designed at KAUST, the test can detect very small amounts of viral RNA in a sample. "Several types of lateral flow tests are currently available or under research for detecting SARS-CoV-2," says KAUST Ph.D. student Tin Marsic. "Depending on how they work, they all have disadvantages, including detecting the virus only several days after infection or producing false positive and false negative results." PCR tests, which are conducted in laboratories, produce more reliable results but are expensive and require sophisticated ...

In recent years, the use of medical cannabis to treat sick kids is on the rise, although questions remain about the benefits and safety of such treatments. Now, a team of researchers from the Hebrew University of Jerusalem (HU) has completed a first-ever meta-analysis of pediatric patients treated with medical cannabis to better understand the risks and benefits of cannabis use among young patients. The meta-review was led by Professor Ilan Matok at HU's School of Pharmacy and the David R. Bloom Center for Pharmacy, along with and PhD candidate Nir Treves. They will present their findings at the 31st Annual International Cannabinoid Research Society Symposium (ICRS) being held in ...

COLUMBUS, Ohio - Instagram users who detect self-promotion or corporate marketing in a post embracing the body positivity movement may be turned off by that dual messaging, new research suggests. In the study, women viewed experimental Instagram posts that borrowed body positive messages from actual users and contained body positive hashtags, such as #bopo. The posts all featured the same initial body positive sentiment, but some posts also asked viewers to either like and follow their profiles and others advertised products or services. Researchers found that participants who spotted self-promotion or advertising considered the posts less morally appropriate and not altogether sincere in their support of the body positivity movement ...

DALLAS, June 21, 2021 — Health care experts urge increased awareness of obstructive sleep apnea among people with cardiovascular disease or risk factors such as high blood pressure, according to a new scientific statement from the American Heart Association, published today in Circulation, the Association’s flagship journal. Obstructive sleep apnea (OSA) occurs in 40% to 80% of people with cardiovascular disease, yet it is under-recognized and undertreated, according to the statement. OSA occurs when an upper airway obstruction causes repeated episodes of disrupted breathing during sleep. Symptoms include snoring, lapses in breathing, fragmented sleep and daytime sleepiness. In general, about 34% of middle-aged men and 17% of middle-aged women meet ...

DALLAS, June 21, 2021 — Older adults taking blood pressure-lowering medications known to cross the blood-brain barrier had better memory recall over time compared to those taking other types of medicines to treat high blood pressure, according to new research published today in the American Heart Association journal Hypertension. High blood pressure, or hypertension, is a risk factor for cognitive decline and dementia in older adults. Nearly half of American adults have elevated blood pressure. Treating high blood pressure with blood pressure-lowering medicines reduced the cases ...

The free, open-source software developed by the Stanford Natural Capital Project creates maps to visualize the links between nature and human wellbeing. City planners and developers can use the software to visualize where investments in nature, such as parks and marshlands, can maximize benefits to people, like protection from flooding and improved health. "This software helps design cities that are better for both people and nature," said Anne Guerry, Chief Strategy Officer and Lead Scientist at the Natural Capital Project. "Urban nature is a multitasking benefactor - the trees ...

São Paulo, Brazil - A multidisciplinary analysis by a group of Brazilian scientists, published online in the journal Scientific Reports on June 21, 2021, revealed that three major factors accounted for the geographic spread of SARS-COV-2 across Brazil, as well as the massive flow of people in search of hospital care throughout the country, during the first wave of the pandemic in 2020. SARS-CoV-2 entered Brazil at the end of February 2020 through the country's international airports. Mathematical modeling revealed that during the first weeks of March 2020, the "super-spreader city" of São Paulo, located next to both the largest Brazilian international ...

First and only report to interview large sample of workers in garment supply chain (1200 workers across 302 factories and four countries) found an increase in risk of forced labour during pandemic This risk has been exacerbated by the response of retail companies, and there is little evidence most have acted in line with their social responsibilities to support their supply chain workers, despite many accessing pandemic recovery funds A new comprehensive system was used during the study to look for the indicators that someone is vulnerable to forced labour The recovery from the pandemic should include support for supply chain workers to mitigate the deterioration ...

Indigenous people living in rural Canada are 16 times more likely to have to travel 200 km or more to give birth than non-Indigenous people, underscoring the need for more access to birthing facilities and providers for Indigenous families in rural regions, found new research published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.201903. Using data from the Canadian Maternity Experiences Survey (MES), this study included 3100 mothers living in rural and small towns in Canada and weighted the sample to represent 31,100 mothers, totaling 1800 Indigenous and 29,300 non-Indigenous mothers. First Nations women living on-reserve were excluded from the MES. Indigenous ...

In rare cases, adults who have recovered from COVID-19 may develop multisystem inflammatory syndrome, and clinicians should consider this possibility in adults with specific symptoms, as physicians describe in a case published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.210232. A 60-year-old man, who had tested positive for SARS-CoV-2 four weeks before, visited hospital for a range of symptoms, including prolonged shortness of breath, high fever, swelling and severe fatigue. Testing found an enlarged heart and lung swelling as well as other issues. "Given the patient's recent history of SARS-CoV-2 infection, fevers without localizing ...

New research uncovers substantial differences in rates of childhood cancers when considering single year of age rather than grouping several years together. The study published by Wiley early online in CANCER, a peer-reviewed journal of the American Cancer Society, also found that minority children have different risks than white children for many types of cancer. Cancer rates among children in the United States are typically reported in 5-year age groups, which may obscure important details. Also, racial and ethnic variations in pediatric cancer rates are typically presented in ...

When a University of Michigan-led research team reported last year that North American migratory birds have been getting smaller over the past four decades and that their wings have gotten a bit longer, the scientists wondered if they were seeing the fingerprint of earlier spring migrations. Multiple studies have demonstrated that birds are migrating earlier in the spring as the world warms. Perhaps the evolutionary pressure to migrate faster and arrive at breeding grounds earlier led to the physical changes the U-M-led team observed. "We know that bird morphology has a major effect on the efficiency and speed of flight, so we became curious whether the environmental ...

University of Maryland School of Medicine (UMSOM) researchers identified a new gene that may be linked to certain neurodevelopmental disorders and intellectual disabilities. The researchers believe that finding genes involved in certain types of developmental disorders, provide an important first step in determining the cause of these disorders and ultimately in developing potential therapies for treating them. The paper was recently published in the American Journal of Human Genetics. About 3 percent of the world's population has intellectual disability. Up to half the cases are due to genetics, however, because many thousands of genes contribute to brain development, it has been difficult to identify the specific cause for each patient. Once the researchers ...
