JAMA Cardiology

2024-11-16

(Press-News.org) About The Study: In this case series study, pulmonary artery systolic, diastolic, and mean pressures of 2 participants with obesity and heart failure with preserved ejection fraction were measured at zero gravity during parabolic flight to assess the effect of external constraint on left ventricular filling pressures.

Amid record year for dengue infections, new study finds climate change responsible for 19% of today’s rising dengue burden

2024-11-16

NEW ORLEANS (November 16, 2024) — Climate change is having a massive global impact on dengue transmission, accounting for 19% of the current dengue burden, with a potential to spark an additional 40%-60% spike by 2050 — and by as much as 150%-200% in some areas — according to a new study presented today at the Annual Meeting of the American Society of Tropical Medicine and Hygiene (ASTMH). The findings from researchers at Stanford and Harvard Universities offer the most definitive evidence to date that climate change is ...

New study finds air pollution increases inflammation primarily in patients with heart disease

2024-11-16

A new study by heart researchers at Intermountain Health in Salt Lake City finds that patients with heart disease, specifically those with heart failure, are especially vulnerable to the impacts of air pollution and poor air quality and can take steps to protect themselves. Results from the Intermountain Health study, presented on Saturday at the American Heart Association’s 2024 Scientific Sessions international conference in Chicago, found that two inflammatory markers — CCL27 (C-C motif chemokine ligand 27) ...

AI finds undiagnosed liver disease in early stages

2024-11-16

SAN DIEGO, California (Nov. 16, 2024) — Liver disease, which is treatable when discovered early, often goes undetected until late stages, but a new study revealed that an algorithm fueled by artificial intelligence can accurately detect early-stage metabolic-associated steatotic liver disease (MASLD) by using electronic health records. The study was scheduled for presentation today at The Liver Meeting, hosted by the American Association for the Study of Liver Diseases. “A significant proportion of patients who meet criteria for MASLD go undiagnosed,” said Ariana Stuart MD, a resident at University of Washington Internal Medicine ...

The American Society of Tropical Medicine and Hygiene and the Bill & Melinda Gates Foundation announce new research fellowship in malaria genomics in honor of professor Dominic Kwiatkowski

2024-11-16

The American Society of Tropical Medicine and Hygiene and the Bill & Melinda Gates Foundation Announce New Research Fellowship in Malaria Genomics in Honor of Professor Dominic Kwiatkowski New Orleans, Louisiana, November 15, 2024 — The American Society of Tropical Medicine and Hygiene (ASTMH) is proud to announce the establishment of the annual Kwiatkowski Fellowship, a new research initiative in partnership with the Bill & Melinda Gates Foundation (BMGF). This fellowship honors the life and scientific contributions of the late Professor Dominic Kwiatkowski, a pioneer in the field of malaria genomics. The ...

Excessive screen time linked to early puberty and accelerated bone growth

2024-11-16

Exposure to blue light, like that from smartphones or tablets, may accelerate bone growth and bone age, leading to early puberty in rats. This research, presented at the 62nd Annual European Society for Paediatric Endocrinology Meeting in Liverpool, sheds light on how the use of blue light-emitting devices could impact growth and development and raises important questions about the long-term health effects in children, who are increasingly exposed to screens from a young age. As children grow and develop, long bones such ...

First nationwide study discovers link between delayed puberty in boys and increased hospital visits

2024-11-16

Swedish young men who went through late puberty during adolescence are more likely to use healthcare services later in life, according to research presented at the 62nd Annual European Society for Paediatric Endocrinology Meeting in Liverpool. The findings of this long-term study suggest that delayed puberty in boys may have harmful effects on their health in adulthood and could potentially lead to new follow-up healthcare routines in the future. Puberty in boys typically starts between the ages of 9 and 14. However, about 2% of boys have delayed puberty, in which puberty does not begin by age 14. In most cases, delayed puberty is constitutional – a pattern of growth and development ...

Traditional Mayan practices have long promoted unique levels of family harmony. But what effect is globalization having?

2024-11-16

A new paper in the journal Child Development shows how some aspects of family interaction among Indigenous people in Guatemala have fundamentally shifted with rapid globalization, yet families have still maintained a unique level of harmony in their interactions. UC Santa Cruz psychologist Barbara Rogoff has been working with Mayan communities in San Pedro la Laguna, Guatemala for five decades and noticed a sophisticated type of fluid, inclusive collaboration among children from these communities. During a research study 30 years ago, mothers and their two small children interacted in a very distinct way, ...

New microfluidic device reveals how the shape of a tumour can predict a cancer’s aggressiveness

2024-11-15

Researchers at the University of Toronto’s Faculty of Applied Science & Engineering have designed a new microfluidic platform that allows forunprecedented control and manipulation of tumor shapes — a largely unexplored area with great potential to advance cancer research. The work, led by Professor Edmond Young, offers new insights into how the shape of tumours can predict cancer cell behaviour and aggressiveness, which opens new pathways for more personalized and targeted cancer care. “While there are several platforms for in vitro modelling of spheroids — ...

Speech Accessibility Project partners with The Matthew Foundation, Massachusetts Down Syndrome Congress

2024-11-15

The Speech Accessibility Project has two new partners — The Matthew Foundation and the Massachusetts Down Syndrome Congress — as it continues to recruit adults with Down syndrome who live in the United States and Canada. The project also allows residents of Puerto Rico to participate. The project is also recruiting those with ALS, cerebral palsy and Parkinson’s disease, as well as individuals who have had a stroke. “The research team has learned that connecting with trusted partners is key to showing the credibility of our work and how much it could improve the lives of people with disabilities,” said Mark ...

Mass General Brigham researchers find too much sitting hurts the heart

2024-11-15

Fitting in a workout after a long day of sitting at a desk might not be enough to compensate for the impacts of sedentary behavior on the heart. Investigators from Mass General Brigham, found that excessive sedentary behavior (waking activity with low energy expenditure while sitting, reclining, or lying down and not including hours spent sleeping at night) was linked to increased risk of heart disease, especially heart failure and cardiovascular death, and that these risks could be significantly reduced by substituting sedentary time for other activities. They also found that meeting guideline levels of moderate-to-vigorous physical activity may be insufficient on its own to reduce cardiovascular ...
