DALLAS - Feb. 18, 2021 - Inhalation of depleted uranium from exploding munitions did not lead to Gulf War illness (GWI) in veterans deployed in the 1991 Persian Gulf War, a new study co-authored by a leading researcher of the disease at UT Southwestern suggests. The findings, published today in Scientific Reports, help eliminate a long-suspected cause of GWI that has attracted international concern for three decades. Using high-precision multicollector mass spectrometry for the first time in such a study, END ...

[Vienna, Feb 18, 2021] Communities worldwide are trying to address inequality. One promising approach could be to look at the design of a city, according to research with real-world data in the journal Nature Communications. An international team of scientists, including members of the Complexity Science Hub Vienna (CSH), show that urban planning directly influences the formation of social networks in a city and subsequently the socio-economic equality or inequality of its citizens. "We know how important social networks are for our social and economic outcomes," explains CSH researcher Johannes Wachs, one of the authors of the paper. Social relations provide individuals with essential access to resources, information, economic opportunities and other forms ...

An irregular sleep schedule can increase a person's risk of depression over the long term as much as getting fewer hours of sleep overall, or staying up late most nights, a new study suggests. Even when it comes to just their mood the next day, people whose waking time varies from day to day may find themselves in as much of a foul mood as those who stayed up extra late the night before, or got up extra early that morning, the study shows. The study, conducted by a team from Michigan Medicine, the University of Michigan's academic medical center, uses data from direct measurements of the sleep and mood of more than 2,100 early-career ...

Researchers have published new insights into the causes of mortality in sepsis Loss of endothelial function is induced through two different pathophysiological processes and is a major driver of septic shock, a life-threatening drop in blood pressure The first pathway originates in the loss of the endothelial barrier triggering an increased production of the repair hormone bioactive Adrenomedullin (bio-ADM), which also has the undesired side effect of vasodilation The second threat acting on the endothelial function is the release of the protease DPP3 into the bloodstream which degrades angiotensin II, a process resulting in decreased vascular tone and cardiac output The different ...

The UK's first national lockdown from March 2020 and its immediate aftermath saw a massive shift in consumer habits that was initially mandated but then lingered as shops and restaurants opened but risks from the virus remained. A new study from the universities of Cambridge and Newcastle used data from the ONS to compare retail, hospitality and online sales in the UK between March and August 2020 with average figures for the same months for the years 2010-2019. Researchers took an approach normally used to estimate cumulative excess deaths to try and measure the impact of the COVID-19 shock on sales of UK retailers and restaurants. They say their economic models suggest that shops predominantly selling food, such as supermarkets, saw ...

Researchers from Dana-Farber Cancer Institute, the U.S. Food and Drug Administration (FDA) and the American Association for Cancer Research (AACR) are releasing recommendations designed to address the under-representation of African Americans in clinical trials for multiple myeloma (MM), a blood cancer that is twice as deadly in this demographic as in whites. The initiative, publishing today in the AACR journal Blood Cancer Discovery, is a "road map" for designing myeloma clinical trials to eliminate racial bias by including more African American patients, as well as gathering "real-world" data from health records about the effects of drugs in African American patients. Through this joint workshop initiated by ...

Among strategies to curb hospital prices among the commercially insured population in the U.S., direct price regulations such as setting rates are likely to achieve greater savings than other approaches like increasing competition or improving price transparency, according to a new RAND Corporation study. But price regulations face the greatest political obstacles and historically have been strongly opposed by medical providers, according to the report. Setting prices for all commercial health care payers could reduce hospital spending by $61.9 billion to $236.6 billion annually if the rates were set as high as 150% to as low as 100% of the amounts paid by the federal Medicare program, ...

An analysis published in the Journal of the American Geriatrics Society indicates that while adults aged 75 years and older do not benefit from taking aspirin to prevent cardiovascular disease, many do so on a regular basis. Also, although statins are known to help prevent heart problems in older adults who have experienced a cardiovascular event, many of these individuals do not take a statin. The analysis included data on 11,392 U.S. adults aged 50 years and older who were surveyed from 2011 to 2018. Investigators found that more than half of participants took aspirin or a statin. "Healthcare providers should inform their older patients about appropriate aspirin use so that they can avoid misuse of aspirin, which can be easily purchased over the counter. Ultimately, ...

African Americans have higher rates of prostate cancer and are more likely to die from the disease than other groups in the United States, likely due to socioeconomic factors, healthcare access problems, and tumor biology. A new review published in Cancer Reports focuses on the biological differences in the development of prostate cancer across ethnicities. The authors note that these differences could be leveraged to improve the diagnosis and treatment of prostate cancer in African American men, ultimately reducing incidence and mortality rates associated with the disease. "We provide a comprehensive review of the significant research in recent years that has examined the molecular and genomic reasons for unequal cancer burden in African American and Caucasian American ...

In an analysis of information on 448 patients with heart failure who were discharged from a hospital in Sweden, 20.3% of patients were readmitted to the hospital within 30 days, and 60.9% were readmitted within 1 year. The END ...

A study published in Environmental Toxicology and Chemistry has found long-term impacts of the 2010 Deepwater Horizon oil spill in the northern Gulf of Mexico on bottlenose dolphins' immune function. Bottlenose dolphins from an area that received prolonged and heavy oiling were temporarily captured, sampled, and released as part of health assessment programs. The animals were compared with dolphins from an area where no oil was observed. Investigators documented immunological alterations in bottlenose dolphins tested up to a decade following the oil spill that were similar in nature to those immediately following the spill. The effects were seen even in dolphins born after the spill. The nature of the immunological ...

A new study published in Economic Inquiry is the first to assess the willingness of consumers to adopt advisory services in the banking sector that are based on artificial intelligence (AI). Investigators examined whether the likelihood that consumers adopt AI in banking services depends on tastes for human interaction across different cultures. The study focused on robo-advisory services, which are automated investment platforms that provide investment advice without the intervention of a human advisor. When investigators analyzed an ING Bank dataset encompassing 11,000 respondents from 11 countries, they found ...

A new study published in the Journal of Bone and Mineral Research has identified various factors that may indicate whether a person faces a higher likelihood of experiencing a bone fracture over the next two decades. The study included 30,446 middle-aged women and men who were followed from the early/mid 1990s to 2016. A total of 8,240 participants (27%) had at least one fracture during a median follow-up of 20.7 years. Older age, female sex, higher body mass index, a previous fracture, a family history of fracture after the age of 50 years, low leisure-time physical activity, heavy work, living alone, smoking, and no or high alcohol consumption were factors independently associated with ...

Among patients with cancer, having additional physical comorbidities was linked with a higher risk of experiencing psychological distress. The finding comes from a Psycho-Oncology analysis of 2017 data from the National Health Survey of Spain. The analysis included 484 patients who reported a cancer diagnosis and 484 matched controls without a history of cancer. Compared with controls, patients with cancer reported more physical comorbidities, including chronic back pain, asthma, chronic bronchitis, urinary incontinence, prostate problems, and kidney problems. ...

Nearly 1.7 million times in the past year, Americans have checked into hospitals to get treated for severe cases of COVID-19. And for the most part, that care hasn't cost them anything, thanks to insurance companies and government programs that absorbed the usual costs patients would owe for any other hospital stay. But as some insurers phase back in those out-of-pocket costs, a new study estimates that many people over 65 hospitalized for COVID-19 in 2021 may owe an average of nearly $1,000 after they get out of the hospital, due to co-pays, deductibles and co-insurance. A few may owe hundreds or thousands more. That estimate is based on a new analysis of out-of-pocket ...

Long black, espresso, or latte, whatever your coffee preference, drink too much and you could be in hot water, especially when it comes to heart health. In a world first genetic study, researchers from the Australian Centre for Precision Health at the University of South Australia found that that long-term, heavy coffee consumption - six or more cups a day - can increase the amount of lipids (fats) in your blood to significantly heighten your risk of cardiovascular disease (CVD). Importantly, this correlation is both positive and dose-dependent, meaning that the more coffee you drink, the greater the risk of CVD. It's ...

PITTSBURGH--"The Queen's Gambit," the recent TV mini-series about a chess master, may have stirred increased interest in chess, but a word to the wise: social media talk about game-piece colors could lead to misunderstandings, at least for hate-speech detection software. That's what a pair of Carnegie Mellon University researchers suspect happened to Antonio Radi?, or "agadmator," a Croatian chess player who hosts a popular YouTube channel. Last June, his account was blocked for "harmful and dangerous" content. YouTube never provided an explanation and reinstated the channel within 24 hours, said Ashiqur R. KhudaBukhsh a project scientist in CMU's Language ...

PULLMAN, Wash. - People tend to listen to big talkers, whether they are women or men. Still, more women prefer not to use assertive language, according to a new study led by Washington State University economist Shanthi Manian. The study, published in Management Science on Feb. 17, found that participants in an experiment more often followed advice when the people giving the advice used assertive "cheap talk," statements that cannot be verified as true. Examples of such statements are often found in job seeking cover letters, such as "I have extremely strong problem-solving ...

Updated results from the CORONADO study, analysing the outcomes of patients with diabetes admitted to hospital with COVID-19, shows that one in five patients die within 28 days while around half are discharged. The study is published in Diabetologia (the journal of the European Association for the Study of Diabetes [EASD]), and is by Professor Bertrand Cariou and Professor Samy Hadjadj, diabetologists at l'institut du thorax, University Hospital Nantes, INSERM, CNRS, and University of Nantes, France, and colleagues. In May 2020, preliminary results from CORONADO (Coronavirus SARS-CoV-2 and Diabetes Outcomes), ...

The tuberculosis (TB) vaccine Bacillus Calmette-Guerin (BCG) could protect newborns against a variety of common infections, such as upper respiratory tract infections, chest infections and diarrhoea, according to a new study in The Lancet Infectious Diseases. The research is the first of its kind to rigorously investigate the full range of illnesses BCG could protect infants against. It suggests that vaccinating all babies on the day of birth with BCG could reduce neonatal infections and death in areas with high infectious disease rates, potentially saving thousands of lives a year. The results also increase the possibility that the vaccine might be used to protect children and adults against ...

Circadian clocks, which regulate the metabolic functions of all living beings over a period of about 24 hours, are one of the most fundamental biological mechanisms. In humans, their disruption is the cause of many metabolic diseases such as diabetes or serious liver diseases. Although scientists have been studying this mechanism for many years, little is known about how it works. Thanks to an observation tool based on bioluminescence, a research team from the University of Geneva (UNIGE) were able to demonstrate that cells that compose a particular organ can be in-phase, even in the absence of the central brain clock or of ...

LA JOLLA--(February 17, 2021) In structural biology, some molecules are so unusual they can only be captured with a unique set of tools. That's precisely how a multi-institutional research team led by Salk scientists defined how antibodies can recognize a compound called phosphohistidine--a highly unstable molecule that has been found to play a central role in some forms of cancer, such as liver and breast cancer and neuroblastoma. These insights not only set up the researchers for more advanced studies on phosphohistidine and its potential role in cancer, but will also enable scientists ...

Deprive a mountain range of its wolves, and soon the burgeoning deer population will strip its slopes bare. "I now suspect that just as a deer herd lives in mortal fear of its wolves, so does a mountain live in mortal fear of its deer," wrote ecologist Aldo Leopold in his landmark 1949 title "A Sand County Almanac." Leopold proposed that predators keep herbivore populations in check to the benefit of an ecosystem's plant life. Remove one link in the food chain, and the effects cascade down its length. The idea of a trophic cascade has since become a mainstay in conservation ecology, with sea urchins as a prime example just off the California ...

Rapid global urbanization has dramatically changed the face of our planet, polluting our atmosphere with greenhouse gases and causing global warming. It is the need of the hour to control our activities and find more sustainable alternatives to preserve what remains of our planet for the generations to come. Carbon dioxide (CO2) and carbon monoxide (CO) make up a large proportion of industrial flue gases. Recent research has shown that certain microorganisms are capable of metabolizing these gases into useful by-products. Thus, attempts are now being directed to ...

BOSTON - Delirium, a common syndrome among older adults, particularly in those who have recently undergone surgery, critically ill patients in the ICU, and in older patients with multiple health issues, is a form of acute confusion that is characterized by poor attention, disorientation, impaired memory, delusions, and abrupt changes in mood and behavior. Moreover, patients who experience delirium are at increased risk of long term cognitive decline. Recently, clinicians and scientists have recognized that delirium is one of the first signs of COVID-19 infection in older patients and that it occurs frequently in patients with severe COVID-19 disease. In a new study led by an interdisciplinary team of gerontologists, geriatricians, precision medicine ...
