Global trends and cross-country inequalities of acute hepatitis E in the elderly, 1990–2021
2025-07-09
(Press-News.org) Background and Aims
Acute hepatitis E (AHE) in the elderly can lead to severe complications including liver failure and mortality, yet the epidemiological landscape remains poorly characterized. This study aimed to assess the burden, trends, and health inequalities of AHE among the elderly over the past three decades, and to further predict its changes by 2030.
Methods
Data on AHE in the elderly were obtained from the Global Burden of Disease 2021. The burden of AHE was analyzed by trends, decomposition, cross-country inequalities, and predictive analysis.
Results
In 2021, the global incidence and Disability-Adjusted Life Years (DALYs) for AHE among the elderly were recorded as 1,130,013.35 and 20,084.77, respectively. Although there were significant differences in the incidence and DALYs across countries, the number of incident cases increased from 1990 to 2021, with a slight rise in age-standardized rates, while the number and age-standardized rate of DALYs showed a declining trend. Decomposition analysis revealed that population growth and aging are the drivers of changes in incidence, while epidemiological changes somewhat offset the increases in DALYs driven by population growth. Low socio-demographic index countries bear a disproportionate burden of elderly AHE, although inequality gaps have narrowed over time. Notably, up to 2030, the number of incident cases and DALYs will continue increasing. The burden in elderly women was more pronounced than in men.
Conclusions
AHE remains a critical public health challenge for the elderly, with rising global incidence and persistent disparities. Population growth and aging are key drivers of this trend, necessitating enhanced prevention strategies to counterbalance their impact. Although SDI-related inequalities have diminished, lower-SDI countries continue to bear a disproportionate burden. Moving forward, tailored interventions that account for regional transmission dynamics, demographic shifts, and gender disparities are essential to reduce the AHE burden and safeguard elderly health worldwide. Policymakers must prioritize adaptable, context-specific measures to strengthen healthcare systems and ensure equitable resource distribution.

A research team led by Dr. Kee Young Koo from the Hydrogen Research Department at the Korea Institute of Energy Research (President: Yi Chang-Keun, hereafter referred to as KIER) has developed a novel and more cost-effective method for synthesizing ammonia decomposition catalysts. This new approach enables more efficient hydrogen production from ammonia and is expected to make a significant contribution to the realization of a hydrogen economy.
Composed of three hydrogen atoms and one nitrogen atom, ammonia has a high hydrogen content, ...

Mesophotic coral ecosystems (MCEs) are important coral ecosystems found between 30 and 150 meters deep in oceans worldwide including the Gulf of America. They support diverse marine life and important fisheries but remain poorly understood. Unlike shallow reefs, MCEs depend on nutrients from the deep ocean from upwelling or river plumes, like those from the Mississippi and Apalachicola rivers. These nutrient flows support growth of marine phytoplankton (i.e. tiny floating algae), which is an important source of organic matter (food) that sustains the corals and other marine species.
However, scientists have ...

PULLMAN, Wash. -- Groundwater is declining across Eastern Washington’s complex, interconnected aquifer system, as people draw on it for irrigation, drinking and other uses at a pace that threatens its sustainability, according to a new study by a Washington State University researcher.
In certain “hot spots” – such as the Odessa region and the Yakima Basin – the rates of decline are particularly significant, with groundwater levels dropping two to three feet a year or more.
The data is built ...

Creatine is popularly known as a muscle-building supplement, but its influence on human muscle function can be a matter of life or death.
“Creatine is very crucial for energy-consuming cells in skeletal muscle throughout the body, but also in the brain and in the heart,” said Chin-Yi Chen, a research scientist at Virginia Tech’s Fralin Biomedical Research Institute at VTC.
Chen is part of a research team working to develop a technique that uses focused ultrasound to deliver creatine directly to the brain. The work, being conducted ...

CO2 concentrations vary widely depending on the source, ranging, for example, from about 0.04% in the atmosphere to about 10% in flue gases. Moreover, these gas streams contain a significant amount of O2 (about 10%), a potent oxidizing agent. To achieve carbon neutrality, it is necessary to develop a robust process that can convert CO2 over a wide concentration range, even in the presence of O2. However, current technology does not offer a single unified approach that can efficiently handle CO2 conversion from trace to high concentrations. To meet this challenge, researchers at Hokkaido University and collaborators ...

WASHINGTON—A new Scientific Statement released today by the Endocrine Society highlights potential research directions related to the pathogenesis of type 1 diabetes (T1D) that should help with the development of new and improved treatment options.
Type 1 diabetes is a chronic disease where the body's immune system attacks and destroys insulin-producing cells in the pancreatic islet. Type 1 diabetes requires lifelong insulin administration and may result in complications such as eye, kidney, nerve, and heart disease. ...

PITTSBURGH, July 9, 2025 — During the menopause transition, only 1 in 5 women have optimal scores using the American Heart Association’s health-assessment tool, known as Life’s Essential 8 (LE8). Among the tool’s eight components, four of them — blood glucose, blood pressure, sleep quality and nicotine use — are key in driving future cardiovascular risks, with sleep being particularly crucial for long-term cardiovascular health.
The findings – published today in Menopause – were made by researchers at the University of Pittsburgh, Albert Einstein College of Medicine and Baylor University.

It’s been recognized for some time that Alzheimer’s disease affects brain regions differently and that tau — a protein known to misbehave — plays an important role in the disease. Normally, tau helps stabilize neurons, but in Alzheimer’s disease, it begins to misfold and tangle inside neurons. It spreads across the brain forming toxic clumps that impair neuronal function and ultimately lead to cell death.
Brain areas like the entorhinal cortex and hippocampus succumb early to tau tangles, while other areas, like the primary sensory cortices, remain resilient to the disease. In the quest to better understand this selective ...

COLUMBUS, Ohio – Have you ever wondered what kind of video content would most grab the attention of monkeys?
A new study of long-tailed macaques suggests the monkeys seem to like some of the same kind of content that humans do: videos featuring aggression and individuals they know.
“Humans and macaques are both social animals who have a fundamental need to belong,” said Brad Bushman, co-author of the study and professor of communication at The Ohio State University.
“It’s not surprising that they both would be most interested in the video content that may help ...
