Gut microbiome may reveal inflammation and future disease risk better than age

Gut microbiota composition explained more variation than chronological age in nearly all inflammatory cytokines and most physiological measures examined, with specific microbial profiles linked to markedly different patterns of inflammation across adulthood. People with the Bacteroides 2 enterotype showed an inflammaging-like profile decades earlier than other groups and had a higher risk of subsequent disease, while a high-diversity microbiota profile was associated with lower inflammation and reduced disease incidence.

Daily steps may match aerobic training for asthma control

For people with moderate to severe asthma, increasing the number of daily steps may be as effective as structured aerobic training sessions for managing the disease.

Scientists develop lab-grown heart tissue model for heart failure

Scientists study the underlying causes of a disease or test new potential drugs in animal models or cells obtained from human biopsy specimens before clinical trials.

Flavorings, colors and sweeteners emerge as UPF markers linked to depression risk

A prospective UK Biobank study of 171,818 adults found that greater estimated exposure to foods containing flavorings, coloring agents, and sweeteners was dose-dependently associated with a higher risk of incident depression over 10.7 years. The findings suggest that specific markers, rather than ultra-processed foods uniformly, may help explain associations between UPF consumption and depression risk.

New BioTAK score accurately identifies Takotsubo syndrome before catheterization

Takotsubo syndrome is an acute heart condition that primarily affects postmenopausal women and is often triggered by severe emotional or physical stress.

New guidelines simplify heart failure phenotypes into two groups

Reflecting improved understanding and treatment advances, new European Society of Cardiology (ESC) Guidelines on heart failure have been published online today in the European Heart Journal and will be presented at ESC Congress 2026 this afternoon.

Review explores complex links between obesity and cardiovascular diseases

Announcing a new article publication for Cardiovascular Innovations and Applications journal. Obesity, given its strong association with cardiovascular diseases (CVDs), is a major global public health issue attracting increasing attention.

Scientists found a distinct gut microbiome pattern in people with symptomatic diverticular disease

A multicenter Japanese study found that symptomatic uncomplicated diverticular disease (SUDD) was associated with reduced gut microbial diversity, increased abundance of the Ruminococcus gnavus group, and depletion of Coprococcus and other butyrate-producing bacteria. Predictive microbiome analysis also identified enrichment of pathways linked to exopolysaccharide biosynthesis and the cell cycle, although the observational design means these associations cannot establish causality.

Disrupted brain-immune signaling may help drive neurodegeneration

A Cell perspective argues that neurodegeneration can emerge from disrupted communication between neural and immune networks, with peripheral immunity, microglia, and gene-regulatory programs all shaping disease processes. The authors propose that restoring immune homeostasis and recalibrating neuroimmune circuits could create new therapeutic and diagnostic opportunities, while emphasizing that many mechanisms remain unresolved in humans.

Multi-organ chip uncovers key mechanisms behind cancer metastasis

Cancer spreading beyond the primary tumor – a process known as metastasis – is responsible for at least two-thirds of cancer deaths.

Why keto appears to lower blood pressure for some people but not others

A narrative review finds that ketogenic diets may modestly lower blood pressure through weight loss, reduced visceral fat, improved insulin sensitivity, fluid and electrolyte shifts, and anti-inflammatory effects. However, effects vary across studies, long-term cardiovascular evidence remains limited, and diet quality, hydration, electrolyte balance, and medication monitoring are important.

Cocoa looks promising for mood, but the brain benefits come with a catch

A review of clinical and preclinical studies suggests cocoa polyphenols may support mood, neuroplasticity, cerebral blood flow, and gut-brain signaling through pathways involving BDNF/CREB, inflammation, and oxidative stress.

New review explores purinergic signaling pathways in osteoarthritis progression

A growing understanding of purinergic signaling is reshaping how scientists view osteoarthritis (OA), revealing an intricate communication network that influences joint inflammation, cartilage degeneration, bone remodeling, and chronic pain.

Disrupted RNA methylation pathway accelerates Alzheimer’s and Parkinson’s risks

A growing understanding of RNA biology is reshaping how scientists view the relationship between environmental toxicants, brain development, and neurodegenerative disease.

Daytime cortisol patterns track cognitive decline but not Alzheimer’s disease risk

In 3,895 older adults, moderate daytime cortisol variability was associated with better cognition and slower decline, while the highest daily cortisol exposure was linked to poorer cognition and faster decline. Cortisol patterns differed between Black and White participants, but their relationships with cognition were similar, and none predicted incident Alzheimer’s disease.

Review outlines effective approaches to reduce recurrent hepatic encephalopathy

Hepatic encephalopathy (HE) is a neurologic complication of advanced liver disease, causing impaired functioning, reduced quality of life (QOL), and increased hospitalisation and mortality.

Researchers train AI to detect diabetes and assign four diagnostic labels

Researchers developed a two-stage machine learning framework that detected diabetes and classified records as prediabetes, type 1, type 2, or type 3c diabetes using two public datasets. XGBoost showed strong internal performance, but inconsistent model rankings, non-standard variables, and the absence of external clinical validation limit immediate use.

YouTube’s health content rewards attention-grabbing videos over reliable medical information

Researchers analyzed 3,958 Korean-language medical YouTube videos and found that clickbait-heavy content attracted more views, likes, and comments. Higher-quality videos from medical professionals and public institutions often received less attention, highlighting a visibility gap in online health information.
