(Press-News.org) The ISCHEMIA trial found no significant difference between an invasive vs. a conservative strategy in patients with chronic coronary syndromes and moderate to severe ischemia at a mean of 3.2 years. However, the cumulative difference in the estimates of cardiac death between the invasive and conservative strategies tended to increase numerically over time (e.g., 0.3% in favor of the invasive strategy at 2 years and 1.3% at 5 years). Because the ISCHEMIA trial was not powered for cardiac mortality and did not focus on long-term follow-up, the rationale for a meta-analysis emerged.
At EuroPCR 2021, Navarese and colleagues present the results of a new meta-analysis of revascularization plus medical therapy versus medical therapy alone. A total of 19,806 patients with chronic coronary syndromes undergoing elective revascularization from 25 randomized trials were pooled, and outcomes were extracted at the longest available follow-up. The primary endpoint was cardiac death. Secondary endpoints were all-cause death, spontaneous myocardial infarction, any myocardial infarction and stroke.
The authors found a statistically significant 21% relative risk reduction in cardiac death with revascularization plus medical therapy (risk ratio 0.79, 95% confidence interval 0.67 to 0.93, p END

World first concept for rechargeable cement-based batteries
2021-05-18
Imagine an entire twenty storey concrete building which can store energy like a giant battery. Thanks to unique research from Chalmers University of Technology, Sweden, such a vision could someday be a reality. Researchers from the Department of Architecture and Civil Engineering recently published an article outlining a new concept for rechargeable batteries - made of cement.
The ever-growing need for sustainable building materials poses great challenges for researchers. Doctor Emma Zhang, formerly of Chalmers University of Technology, Sweden, joined Professor Luping Tang's research group several years ago to search for the building materials of the future. Together they have now succeeded in developing a world-first ...
'We're playing Moneyball with building assets'
2021-05-18
Researchers have developed a tool to help governments and other organizations with limited budgets spend money on building repairs more wisely.
The new tool uses artificial intelligence (AI) and text mining techniques to analyze written inspection reports and determine which work is most urgently needed.
"Those assessments are now largely subjective, the opinions of people based on experience and training," said Kareem Mostafa, an engineering PhD student at the University of Waterloo who led the project. "We're using actual data on buildings to make spending decisions more objective."
Researchers looked at inspection reports on the roofs of 400 schools managed by the Toronto District School Board. A computer ...
Uninsured cancer patients 60-64 face worse outcomes than Medicare beneficiaries aged 66-69
2021-05-18
MUSC Hollings Cancer Center lung cancer researcher Gerard Silvestri, M.D., found that a lack of insurance leads to worse cancer survival than for those with Medicare, in a paper published in the May issue of Health Affairs. This work, a joint effort between Silvestri and researchers at the American Cancer Society, highlights the current dire barrier in medical care: Many people cannot take advantage of the newer potentially lifesaving treatments due to the high costs.
Silvestri said the research began last year, inspired by the hotly debated topic of expanding Medicare ...
Fast, affordable solution proposed for transparent displays and semiconductors
2021-05-17
The Korea Institute of Machinery and Materials (KIMM) under the Ministry of Science and ICT developed a roll-based damage-free transfer technique that allows two-dimensional (2D) nanomaterials to be transferred into wafer scale without damage. The proposed technique has a variety of applications from transparent displays and semiconductors to displays for self-driving cars, and is expected to accelerate the commercialization of 2D nanomaterial-based high-performance devices.
Dr. Kwang-Seop Kim, principal researcher of the Department of Nano-Mechanics at KIMM, succeeded in developing a technique of transferring 2D nanomaterials, as thin as 1/50,000 of a strand of hair, to a substrate of at least 4 inches (approx. 10 cm) without damage.
The roll-based transfer is a process in ...
Caltech professor helps solve Hindenburg disaster
2021-05-17
On the evening of May 6, 1937, the largest aircraft ever built by mankind, a towering example of technological prowess, slipped through the stormy skies of New Jersey and prepared to land. The airship Hindenburg was nearing the end of a three-day voyage across the Atlantic Ocean from Frankfurt, Germany. It was a spectacle and a news event. Onlookers and news crews gathered to watch the 800-foot-long behemoth touch down.
And then, in one horrifying half minute, it was all over. Flames erupted from the airship's skin, fed by the flammable hydrogen gas that ...
Research reveals potential treatment to prevent obesity-driven liver damage
2021-05-17
One of the especially dangerous health risks of being extremely overweight occurs when an obese person begins to accumulate fat in their liver.
This condition--non-alcoholic fatty liver disease (NAFLD)--is the world's most common chronic liver disease and is the primary underlying cause for liver transplants in children and adults. Without such transplants, which are available to only a small percentage of patients, NAFLD over time can be fatal. In fact, (excluding alcohol-related liver damage) more than 30,000 people a year die from NAFLD.
For years, the primary way to treat NAFLD has ...
Study shows early preterm births can be decreased with DHA supplementation
2021-05-17
Early preterm births may be dramatically decreased with docosahexaenoic acid (DHA) supplements, with a dose of 1000 mg more effective for pregnant women with low DHA levels than the 200 mg found in some prenatal supplements, according to a study led by researchers from the University of Kansas and the University of Cincinnati and published today in EClinicalMedicine, a clinical journal of The Lancet. Early preterm birth, defined as birth before 34 weeks gestation, is a serious public health issue because these births result in the highest risk of infant mortality and child disability.
"This study tells us that pregnant women should be taking DHA," said Susan E. Carlson, Ph.D., professor of nutrition in the Department ...
COVID-19 monoclonal antibodies reduce risk of hospitalization and death
2021-05-17
PITTSBURGH, May 17, 2021 - Monoclonal antibodies, a COVID-19 treatment given early after coronavirus infection, cut the risk of hospitalization and death by 60% in those most likely to suffer complications of the disease, according to an analysis of UPMC patients who received the medication compared to similar patients who did not.
UPMC and University of Pittsburgh School of Medicine physician-scientists published the findings today in Open Forum Infectious Diseases, a journal of the Infectious Diseases Society of America. The study involved bamlanivimab, a monoclonal antibody that is now offered only in combination ...
Linguistic and biological diversity linked
2021-05-17
Cultural diversity -- indicated by linguistic diversity -- and biodiversity are linked, and their connection may be another way to preserve both natural environments and Indigenous populations in Africa and perhaps worldwide, according to an international team of researchers.
"The punchline is, that if you are interested in conserving biological diversity, excluding the Indigenous people who likely helped create that diversity in the first place may be a really bad idea," said Larry Gorenflo, professor of landscape architecture, geography and African studies, Penn State. "Humans are part of ecosystems and I hope this study will usher in a more committed effort to engage Indigenous people in conserving localities containing key biodiversity."
Gorenflo, ...
Indigenous co-management essential for protecting, restoring Bears Ears region
2021-05-17
Indigenous people have lived in the Bears Ears region of southeastern Utah for millennia. Ancestral Pueblos built elaborate houses, check dams, agricultural terraces and other modifications of the landscape, leaving ecological legacies that persist to this day. Identifying how humans interacted with past environments is critical for informing how best to protect archaeological sites and ecological diversity in the present. This "archaeo-ecosystem" approach would facilitate co-management of public lands in ways that promote Indigenous health, cultural reclamation and sovereignty.
For the first time, a new study evaluated ecological legacies, archaeo-ecosystem restoration and Indigenous ...
