A new study, presented today at the AATS 101st Annual Meeting, found that patients treated surgically for segmental Chronic Thromboembolic Pulmonary Hypertension (CTEPH) had excellent outcomes with the vast majority doing very well in the long term without any additional treatment other than surgery.

A new study, presented today at the AATS 101st Annual Meeting, shows an association between decreased survival at five years and leaving an atrial communication at biventricular repair of unbalanced AVSD after adjusting for other known risk factors. The study sought to determine factors associated with mortality after biventricular repair of AVSD.

An international team led by SPECS Lab at the Institute for Bioengineering of Catalonia (IBEC) reveals how the brain improves through self-supervised learning. Researchers also propose a novel brain-based solution to solve a fundamental challenge in artificial intelligence: how machines could learn without direct supervision. In their opinion article, scientists provide evidence for their hypothesis and new insights into the anatomy and physiology of the core memory system in the human brain: the hippocampus.

Preliminary results of a clinical trial, presented today at the AATS 101st Annual Meeting, showed that a new, low-profile thoracic aortic endograft is safe and effective in the treatment of descending thoracic aortic aneurysm or penetrating atherosclerotic ulcer (PAU) diseases.

A new study, presented today at the AATS 101st Annual Meeting, and simultaneously published in the Journal of the American College of Cardiology, finds that patients suffering from severe mitral regurgitation should be carefully screened and counselled before undergoing transcatheter edge-to-edge mitral repair (TEER).

A new study presented today at the AATS 101st Annual Meeting, found that the percentage of patients undergoing esophagectomy for cancer who suffer Venous Thromboembolism (VTE) post-operatively is much higher than previously reported, with as many as 24 percent suffering from Deep Vein Thrombosis (DVT) or Pulmonary Embolism (PE). Six-month mortality for patients with VTE was 17.6 percent compared to 2.1 percent for those without.

A new study by The Ohio State University College of Nursing found that critical care nurses nationwide reported alarmingly high levels of stress, depressive symptoms and anxiety even before the COVID-19 pandemic began. These factors correlated with an increase in self-reported medical errors.

To make a greater impact, scholars need to overcome the curse of knowledge so they can package their ideas with concrete, technical, and active writing.

The information presented in this study is primarily positioned to benefit scientists and experts in regenerative medicine where new tools strategies to treat liver diseases are required. The evidence presented in this manuscript illustrates exploiting small extracellular vesicles (sEVs) derived from interferon-γ (IFN-γ) pre-conditioned MSCs (γ-sEVs) can be a foundational formulation for a therapeutic solution that will be accessible, cost effective, and efficacious in treating liver diseases.

31% of pet dogs and 40% of pet cats tested positive to COVID-19 after their owners' own diagnoses, though under half displayed symptoms, in small Brazilian study.

In a recent article published in the Journal of the Association for Information Science and Technology, researchers discuss how bad user design is especially detrimental to the underprivileged and how a wider usability movement can help 'everyone, everywhere.'

Largest study so far of more than 17 million adults in England confirms that minority ethnic groups had a higher risk of testing positive, hospitalisation, admission to intensive care units (ICU), and death from COVID-19 compared with white groups, even after accounting for other factors known to increase risk like deprivation, occupation, household size and underlying health conditions.

Supporting female survivors of childhood maltreatment is critical to disrupting intergenerational abuse as new research from the University of South Australia shows a clear link between parents who have suffered abuse and the likelihood of their children suffering the same fate.

The marine worm Ramisyllis multicaudata is one of only two such species possessing a branching body, with one head and multiple posterior ends. An international research team led by the Universities of Göttingen and Madrid is the first to describe the internal anatomy of this intriguing animal. The researchers discovered that the complex body of this worm spreads extensively in the canals of their host sponges. Results were published in the Journal of Morphology.

A Phase II trial at MD Anderson tound that BK virus (BKV)-specific T cells from healthy donors were safe and effective as an off-the-shelf therapy for BKV-associated hemorrhagic cystitis (BKV-HC), a painful complication common after allogeneic stem cell transplants for patients with leukemia or lymphoma.

A team of University of Virginia School of Engineering computer science researchers has uncovered a line of attack that breaks all Spectre defenses, meaning that billions of computers and other devices across the globe are just as vulnerable today as they were when Spectre was first announced.

Rice University and Lawrence Livermore National Laboratory engineers are using neural networks to accelerate predictions of how the microstructures of materials evolve. The machine-learning technique should speed the development of novel materials.

Scientists from several hospitals and research centers have shown what happens in the tissues of patients who died of COVID-19. In a study published in Nature, the researchers describe how infected cells from multiple organs exhibited a range of molecular and genomic changes. They also saw signs of multiple, unsuccessful attempts by the lungs to repair themselves in response to respiratory failure -- the leading cause of death in COVID-19 patients.

A new study assessed how the tool was developed and is used, finding that a greater proportion of inmates could reduce their risk and become eligible for early release over time if they participated in a re-entry program and did not incur infractions. This finding has implications for efforts to reduce prison populations during the COVID-19 pandemic.

In a study of people's reactions to radio host Rush Limbaugh's announcement of a lung cancer diagnosis and Kentucky Sen. Rand Paul's announcement of a diagnosis of COVID-19, researchers at Penn State found that those who took pleasure in their misfortune were themselves less likely to take steps to prevent lung cancer or COVID-19.
